Affect of Internet on Print Media - Essay Example The paper evaluates the hypothesis about the presumed replacement effect on print media of internet. Discussion The issue of the impact of internet on traditional print media has been investigated by researchers in certain disciplines. Various facets of internet vs. print media are analyzed. Internet vs. Printed News Levmor and Craven (2011) evaluates the area of news publications for effect of internet on print media. Levmor and Craven (2011) states that online channel has caused a declining effect on print media in the context of news publication and consumption. The reason for this impact is ascribed by Levmor and Craven (2011) to benefits of online news over print news. Online news has the functionality of having the facility to place news stories into better context by including photo galleries, videos, and hyperlinks to different sources or relevant articles published online. The superior level of customization for individual reader made possible with the Internet gives it a re markable edge over print media. Several newspapers have gone out of business or shifted to online model during the last ten years (Baigi, 2011). Dijkstra, Buijtels and Raaij (2008) adopted a circulation model to understand the impact of interent on physical news publication business by using circulation measure rather than readership model. Circulation of printed news pertains to the cumulative number of individual copies distributed or printed, while readership relates to the total count of people reading a publication taking into account borrowing and sharing, as well (Dijkstra, Buijtels and Raaij, 2008). The former was utilized due to greater accuracy of the count. A positive correlation was found between growths...Internet is referred to as a worldwide system of computer networks which is based on the use of routing of data and information in electronic form. Internet forms a global information space and is the physical basis for the World Wide Web and many other systems for dat a transfer. At the present time the internet is fastest growing medium and it is used in everyday life. There have been observable impacts on magazines and newspapers and related print media after free digital content became widespread. One can expect that free digital content would eventually cannibalize entire sales of print media. Introduction Print media refers to all means of dissemination of written information, which includes newspapers, periodical publications  and books. Print media has evolved into new forms of newer forms in recent years like free newspapers and targeted magazines for specific population groups. Print media is generally perceived to have receded in the late  twentieth  century and early  twenty-first  century. Internet forms a global  information space  and is the physical basis for  the World Wide Web and many other systems for data transfer. At the present time the internet is fastest growing medium and it is used in everyday life. It is frequently hypnotized that emergence of internet and growth of internet technologies is causing a continuous decline in consumption of print media. Rationale for this supposition is asserted as the ease of access of online medium and low cost. The paper evaluates the hypothesis about the presumed replacement effect on print media of internet. Print media is generally perceived to have receded in consumption. The phenomenon of diffusion of the press is taking place at a rapid pace while distribution of newspapers and magazines is decreasing. Evidence is present to support the fact that internet contains greater diversity of information and is less regulated by governmental authorities and power groups than printed media. For this reason, internet is being favored by the readers and several newspapers have gone out of business or shifted to online model during the last ten years. Also it is concluded that a positive correlation is found between growths of internet penetration among masses with the reduction in newspaper circulation. Nevertheless, a highly interesting observation put forwarded by some thinkers it that the internet is not economically viable mode of publishing and communication.

Masking Poor Communication Essay Example | Topics and Well Written Essays - 500 words

Masking Poor Communication - Essay Example I remember the time when I told my husband that it would be nice to go on a vacation during the Christmas break. On my mind however, we cannot afford the vacation yet because of some bills which we still have to pay. Unfortunately, my husband thought that I was making a hint for him to plan a vacation. I assumed that he understood that it was just a thought and did not require a plan of action. On his end, he assumed that I was asking him to schedule one. What happened is we had to go ahead with the vacation since the booking was made already but of course, I felt it was an unnecessary expense. The good thing though is that we both enjoyed our time together. But miscommunication does not always have a happy ending. Some of our miscommunication experiences are sometimes quite frustrating. To try to resolve this problem of miscommunication and to make sure that it will be minimized in the future, it is important that I do not assume that I understand or my partner understands (Thompson , n.d.). I should confirm what I heard by repeating what the other person said. If for example, my partner told me that we will meet at the corner coffee shop at 9:00 am, I will confirm by repeating and saying, â€Å"We will meet at the corner coffee shop at 9:00 am.† The implicit rule is to double check with each other (Thompson, n.d.).

Gigabit 10 Gigabit Networking Applications

Gigabit 10 Gigabit Networking Applications Ethernet Ethernet technology refers to a packaged based network that is most suitable for LAN (local area network) Environments and includes LAN products of the IEEE 802.3ae. 10 Gigabit Ethernet standards which is an up gradation on all other earlier versions, works on an optical fibre and operates in full duplex mode (Held, 1996). The IEEE 802.3ae is an upgraded version of the IEEE 802.3 base version developed as early as 1980. Ethernet technology originated nearly 30 years ago as a least expensive high-speed LAN based option (Ferrero, 1996). Ethernet defines the CSMA/CD protocol and is currently used in major LAN-based settings. Ethernet has the advantages of low implementation cost, simplicity and ease of installation and maintenance, reliability and compatibility with LAN based networks. Almost all Internet traffic generates and terminates with an Ethernet connection, which has been adapted for higher speeds and the volume of traffic over the Internet. Ethernet technology is rapidly changing and the new 10 Gigabit technologies maintains certain older characteristics like package format and at the same time adapts itself to faster connections, higher speeds and more efficient handling of internet traffic. The newer versions of Ethernet like the Gigabit Ethernet and10 Gigabit technologies have wide-ranging applicability in LAN, WAN,MAN and SWAN (Axel son, 2003). We will discuss these points in greater detail in the dissertation beginning our discussion with a brief description of Ethernet technology, its history, modes of operations, Gigabit architecture and applications and the rise of the 10 Gigabit technology in Ethernet applications. In our final analysis we will analyse the uses of Gigabit technology and the advantages involved. We would also discuss the market demands as far as setting up the new technology in business and enterprises is concerned and conclude with a final short summary giving the prospects of Ethernet and Gigabit Ethernet in this information savvy New Age. Ethernet Technology: Ethernet tends to connect computers using hardware that could be used on different linking machines and workstations. It differs from the Internet because the Internet connects remotely located computers with telephone or cable line or a software system. Ethernet uses software but connects in LAN on the basis of hardware and the Ethernet patent is referred to as the Multipoint data communication system with collision detection. Ethernet was the first technology that could connect through LAN hundreds of computers located in the same region or building(Spurgeon, 2000). Ethernet technology can be used on optical fibre and twisted cables and it operates on a half-duplex and in recent versions, full duplex mode. There are three major varieties of Ethernet and these are Gigabit Ethernet, 10Base T Ethernet and Fast Ethernet that supports data transfer rate of 100mbps. Ethernet uses a star or bus topology and supports a data transfer rate of 10 mbps. The CSMA/CD protocols aroused to handle simultaneous demands and workloads. The newest Gigabit version supports a transfer rate of 1000 megabits per second and thus has a speed of a 1000mbps. Ethernet is the most widely used LA standards. Ethernet specifications are used in IEEE 802.3 standard software and specify physical software layers within the system. Ethernet is used in nearly 90% of LAN workstations and LAN-connected PCs in the world (Lee and Lee 2002). Although Ethernet is the most popular physical layer of LAN technology that is in use, the other common LAN types include the Token ring, Fibre Distributed Data Interface (FDDI), Local Talk, Asynchronous Transfer Mode or ATM, Fast Ethernet, a more advanced variety of Ethernet and Gigabit technology. Ethernet helps in giving a high-speed connection along with the ease and convenience of installation and maintenance. Ethernet applications and installation are comparatively inexpensive and it has wide applicability and compatibility with LAN and other widely used networks but LAN is the most popular compatible networking. Ethernet inacceptable in the computer market and supports all popular network protocols making Ethernet the ideal networking technology for all computers used at present. The Ethernet standard is set at IEEE 802.3,deriving its name from the Institute of Electrical and Electronic Engineers (IEEE), which defines this, standard. An adherence to the standards can ensure the efficient communication and links between the networking equipment’s and the networking protocols. The IEEE standard802.3 defines the rules for configuring an Ethernet network and also specifies how the elements in an Ethernet network can actually interact with each other. Brief History about Ethernet: Ethernet originated nearly 30 years ago when Xerox corporation used an experimental coaxial cable network with an original transfer rate of just 3 mbps using a CSMA/CD (carrier sense multiple access/collision detect protocol that could be used in then existing LAN and that could support some heavy traffic. This experimentation and development of the first Ethernet technology received some attention and around 1976-1980,DEC (Digital Equipment Corporation) and Intel joined Xerox Corporation to develop a LAN architecture that supported a data rate of 10 mbps. This was the Ethernet version 1.0 specification and the original version of IEEE 802.3 was also based on this initial Ethernet version specification. The draft of IEEE 802.3 version received its approval in1983 and was specified as an official standard by the IEEE in 1985.Ethernet and IEEE 802.3 and all versions of these are ultimately compatible, derived from and improved versions of this basic version of original Ethernet technology. A number of supplemental versions and technologically upgraded and advanced versions have been used to support higher data transfer rates. Thus Ethernet technology saw gradual development with a gradual LAN technology development in the1970s to the formation of IEEE subcommittee and approval of Ethernet version IEEE 802.3 later declared as standard in the 1980s. This was upgraded further with the development of Fast Ethernet and an associated speed of 100 mbps in 1995 with the final 1000 mbps Gigabit standards approved in the middle of June 1998. Ethernet Explained: A general description of what is Ethernet and how it works can be given as Ethernet seems to be based on the idea of a group of people within the same location and on the same network sending messages through a radio system and using a common wire or channel and this has been referred to as ether, a supposed medium that 19th century physicists believed helped in the propagation of light. Each member in the system seems to have a 48-bit key MAC address assigned to the network-interface card and this makes sure that all systems within the Ethernet network have their own distinct addresses. As Ethernet is found and available and compatible nearly everywhere with wide ranging applicability, manufacturers tend to build the functionality of an Ethernet card directly into PC motherboards, which are printed circuit boards used in personal computers, also known as main boards. In the initial stages of its development and discovery, Ethernet used shared coaxial cable, which was found in the building attached to every connected machine brought within the system. All computers in a building were connected to an attachment unit interface (AUI)transceiver and this in turn connected to another cable. A simple passive wire was used for small Ethernets and was considered not quite applicable to large extended networks as any damage to the wire could actually make the Ethernet segment dysfunctional. Within the Ethernet technology, the systems are run in such a way that all communications between PCs, happen along the same wire, and information transmitted bygone computer is received by all computers in the network even if the information was meant to go only to one computer or specific destination. The interface card of the network filters out all information that is not originally addressed to the entire network and the CPU is interrupted when applicable packets are received. This information sharing by all computers is considered one of the weaker points of the shared medium of Ethernet since any node within the entire network connected by the Ethernet can dig out information that seems to have been originally meant for a single location. Thus all traffic within the single wire used for the technology, can be intercepted and manipulated. A single cable thus has its ups and downs because not only is there an information security risk with such networking, the bandwidth is also shared so after a power failure or are start, traffic can crawl to a point that it can cause a slowing down of information transmission and data transfer due to too much crowding within a single wire. The computers with an Ethernet connection networking share the channel using the CSMA/CD technology that stands for Carrier Sense Multiple Access with Collision Detection. The CSMA was first developed and used for ALOHA net in Hawaii and is comparable to token Ring and master controlled networks we have discussed here. An algorithm is generally followed when the computers transmits data and there can be several commands from start, transmitting, end transmission, wire busy, to wire idle and transmission stopped or maximum transmission attempts exceeded. In this way, a medium, the Ethernet is chosen through computers try to transmit information. When there is too much traffic, there is an apparent cessation of these attempts, which renews again after a random period of time. This aid in avoiding collision and an exponential increase of back-off times are used when there is more than one failed attempt of transmission. Depending on the type of medium used Ethernet segments can have restricted size. A 10BASE5 coax cable can only have a maximum length of500 metres. An Ethernet repeater can be used to have a bigger length cable and this device uses the signal from one Ethernet cable and repeats it into another cable. This way Ethernet repeaters can be used to connect up to five different segments with a maximum three of these devices used as attached devices. Since many segments are connected, cable breakages can be handled more efficiently. Thus when any one of the Ethernet segments breaks off, most of the devices are unable to communicate as connections are broken, however Ethernet repeaters allow the workings of different segments separately which can continue to work despite the cable breakage in one part of the network (Quinn,1997). Ethernet segments can usually be terminated with a resistor at both its ends within the network and as for the equipment’s used, each end of the coaxial cable must have 50 ohm resistor and head sink and this is called the terminator affixed to an N or BNC connector. When resistors are not used, it is usually perceived as a cable breakage and consequences will be such that the alternating current signal transmitted will be reflected and as a reflected signal is indistinguishable from a collision, similar results as in collision will take place with complete cut-off of all communication between the units. When Ethernet repeaters are used electrically different segments can continue to function even in isolation as separate units and this helps in regenerating and retiming the signals (Field, et al 2002). Most repeaters have an auto-partition function and this means they are capable of removing and isolating a segment from service when there are too many collisions, breakages, and traffic or when the collisions last too long. This is done to prevent the other segments from getting affected by such collisions or breakages and once there is a renewal of activities that are smooth and without collisions, the Ethernet repeaters reconnect the unattached segment to the original network. The advantages of using cables in the star Ethernet system has been used effectively by net workers who create Ethernet repeaters with multiple ports known as Ethernet hubs or fan outs that could be connected to other hubs or coax backbones. The earlier hubs were also known as multiport transceivers and DECs DELNI is one such example of an Ethernet fan out. Multiport transceivers allow the sharing of single transceiver by multiple hosts having AUI connections. This also allows the working of a standalone single Ethernet segment that does not essentially require a coax cable. Companies such as the DEC and Synoptic sold many multiport transceivers that could connect many10BASE-2 thin coaxial segments. However, coaxial Ethernet segments have been made obsolete by the development of unshielded twisted pair cables(UTP), which began with Starling and continued with 10BASE-T. The new developed of the unshielded twisted pair variety allowed Cat-3/ Cat-5cables and RJ45 telephone connectors to connect the fan outs to the ends. This further helped to replace the coaxial and AUI cables. Unshielded twisted pair Ethernet takes the termination problem into consideration and every segment is taken separately so that the termination could be built as a hardware component without requiring special and separate external resistor. However despite the development of the star topology, Ethernet networks use a half-duplex transmission access method and also use the CSMA/With minimal cooperation from the hub that deals with packet collisions. Every packet transmitted is sent to every port and node of the hub so what really remains are bandwidth and security problems due to this open information sharing, so to speak. Since the chance of collisions is proportional to the number of transmitters and the data that have to be transmitted, implying that the larger the amount of data sent, the higher are the chances of packet collisions. Modes of Operation: The Ethernet network elements have interconnecting media and network nodes which basically falls into two major classes known as the Data terminal equipment (DTE) which are the PCs, workstations, servers, and are usually the destination or source of data frames often referred toast end stations; the other category of network node is the Data communication equipment (DCE) that are the standalone intermediate devices such as the repeaters, interface cards, modems, switchers or routers (Hancock, 1988). The DCEs are intermediate network devices that receive and forward data frames across the entire network. The traditional Ethernet and IEEE 802.3 variety works in a half-duplex mode. For the other mode of operation as in Full-duplex CSMA/CD is not used. Auto-negotiation is another mode of operation for the Ethernet. Half-Duplex Mode of Transmission/ CSMA/CD Access Method: The Half-Duplex mode of transmission was developed in the original version of IEEE 802.3 Ethernet application and the CSMA/CD is considered as a means by which two or more stations could share common media in an environment that is switch less and does not require arbitration, or assigned time slots to indicate when workstations are ready to transmit information. This means that individual Ethernet Macias capable of determining when it can send a frame. The CSMA/CD access rules are given in the full form of the CSMA/Protocol as it involves Carrier sense multiple access and Collision Detect. Carrier sense implies that each station continuously keeps alert for traffic on the medium to determine when gaps between frame transmissions are seen. ‘Multiple access’ refers to stations that may begin transmission any time they detect that there is no traffic and the network is relatively quiet. Collision detect acronym implies that when there are two or more stations in the CSMA/CD network and if they begin transmitting data at the same instance the streams of bits from each of the workstations will collide with each other and both the transmissions which collide will then become unreadable (Halaby and McPherson, 2000). Each transmitting station should be able to determine and detect that a collision has taken place before the station has finished sending its frame. Each transmitting station then must stop transmitting any further data as soon as a collision is detected and then this workstation must show a state of abeyance in its activity for random length of time determined by a back-off algorithm before attempting to retransmit the frame all over again. In certain situations when two distant stations on the network need to send a frame and the second station does not even begin transmitting until just before frame of the first station arrives. In that case, the collision is detected immediately by the second station yet the first station does not detect it until the corrupted frame signal goes all the way to the station. The time required to detect a collision can reach a twice the time required for the signal propagation between two distant stations on the network situated at farthest points (Quinn,1997). This suggests that the maximum collision diameter and minimum frame length are directly related to the slot time and longer minimum frame lengths translate to longer slot times and larger collision diameters where the shorter the minimum frame lengths are they correspond to shorter slot times and smaller collision diameters. There was growing understanding and need to reduce the impact of collision recovery and the need for network diameters to be large enough to accommodate networks, which are large, sized. The general consensus was to choose the maximum network diameter of around 2500metres, and to set the minimum frame length to ensure that all potentially damaging collisions are reported quickly. This system worked for 10mbps speed of Ethernet but for higher transfer rate Ethernet connections and developers such as the Fast Ethernet, backward compatibility with earlier Ethernet networks were necessary and this involved the inclusion of the existing IEEE 802.3 frame format and error detection procedures as also all the networking software and applications which could run on the 10mbps networks (Quinn, 1997). For all transmission rates, the time required to transmit a frame is inversely related the transmission rate and at 100 mbps, a minimum length frame could be transmitted at one tenth of the defined and original slot time and so any collision that might occur at this time would go undetected. The maximum network diameters used and specified for 10 mbps could not be used for 1000mbps networks. Fast Ethernet networks and connections help in reducing the maximum network diameter by more than 200 meters. This problem is also seen in the Gigabit Ethernet, as there is a decrease in network diameters by a factor of 10to more than 20 meters for 1000 mbps operations. This is however potential hindrance although as a solution the same maximum collision domain diameters were used to increase the minimum frame size adding an extension field to frames shorter than the minimum lengths. Full-Duplex Mode: The full-duplex mode allows the simultaneous two way transmission of data along the same or one link. The full-Duplex mode is an MA capability that allows the two-way transmission of information over point-to-point links. This Full-duplex transmission is functionally much simpler than half duplex transmissions as no collisions, media contentions, schedule retransmissions and extension bits on short frames ends are involved. Since there is a reduction is the procedural complications, more time is available for transmission and there is also a doubling of link bandwidth and each width is capable of supporting full-rate, simultaneous two way transmission of data frames and each transmission begins as soon as frames are ready to send. The main restriction is inter-frame gap between two successive frames that has to be of a minimum specified length. Usually all frames conform tithe Ethernet standard frame formats. Ethernet Types: Apart from the broad varieties of Ethernet types that transmit data at10mbps (Ethernet), 100mbps (Fast Ethernet) and 1000 mbps (Gigabit Ethernet), 10 Gigabit Ethernet and the earlier varieties such as Starling, there can be variations in the Ethernet frame types as well. We give a brief description of Ethernet types below. The earliest and first varieties of Ethernet was the Xerox Ethernet which was the original 3m bit per second Ethernet implementation and had versions 1 and 2(Hall, 2003).The framing format version 2 is stilling use. The other earlier Ethernet application 10BROAD36 is now no longer used although it was one of the earlier standards supporting Ethernet overlong ranges. The broadband modulation techniques are similar as founding cable modems and systems operated on coaxial cables. Starling or 1BASE5 as the first Ethernet implementation on twisted paired wiring and operated at 1mbps speed. This was gradually replaced by the other versions. Among the more recent versions of the 10 mbps Ethernet is the 10BASE5that uses thick net coaxial cables also called thick wire or yellow cable is the original implementation of the 10mbps Ethernet. Transceivers could be connected using a vampire tap and connecting the core and the screen with N connectors. There is a cable that could be used to connect the transceiver to the AUI or Attachment unit Interface. This type of Ethernet can have 5 network segments with 4repeaters, with three of the segments that could be connected to the network. The bus topology is used here and the maximum segment lengths 500 meters with the overall length at 2500 metres. The minimum length between nodes is stipulated at 2.5 metres with the maximum number of nodes per segment at 100. This system is obsolete as of now. 10BASE2 uses the thin net coaxial cable, also called the Thin wire or Cheaper net, a BNC connector and bus topology with a terminator at the end of each cable. The cable specified for its purposes is RG-58 A/U orRG-58C/U with a 50 ohms resistance. the 5-4-3 rule is applicable here meaning like the 10BASE5 Ethernet there are 5 network segments, 4repeaters and 3 of these could be connected to computers. 185-200metres is the maximum length for each segment and each machine uses at-adaptor to connect with a BNC connector. Although signal quality is considerably reduced with each barrel connector, barrel connectors could be added to link the smaller cable pieces in the network. Length between nodes is given at a minimum of 0.5 meters. This is one of the more widely used Ethernet applications. The Starling which was the first Ethernet twisted wire implementation later evolved into 10BASETwhich comprises of 4 wires and two twisted pairs with a Cat-3 or Cat-5 cable of up to 100 meters in length. At the middle of the connection is a hub or switch, which has a port for each node. The 10BASET uses star topology and as we mentioned 2 pairs of unshielded twisted wires. This category of the Ethernet is not subject to the 5-4-3 rule and can use 3, 4 or 5 cables with the best performance given by category 5 cable. The maximum segment length here is 100 meters. Maximum number of connected segments can be nearly thousand. The minimum length between nodes is 2.5 meters. Whereas only1 node can be present in every segment using the star topology, this system uses RJ-45 connectors. 10BASEF is the generic name for 10 Ambits/s Ethernet standards using fibre optic cable extending up to 2 mms in length. The number of network nodes can be 1024 with a maximum segment length of 200 meters. Specialized connectors for fibre optic cables are used here. This has three main varieties: the 10BASEFL is an updated and more advanced version of the FOIRL standard. FOIRL is the Fibre-optic inter-repeater link and the original standard for Ethernet on fibre optic. This Ethernet type is used to connect computers in a LAN setting a task not done mainly due to the incurring costs. This is the most widely used of the 10BASEF Ethernet type. The 10BASEFB that has never been used serves as a backbone between hubs. The 10BASEFP is a star network that does not require a repeater for its connections connect a number of computers with hubs and switches and gets cable distances up to 500metres. The 100BASET is also known as the Fast Ethernet and is a generic term for any of the three standard varieties if Ethernet that transfers data at 100mbits/s over twisted cables up to 100 meters long. These three varieties include 100-BASETX, 100BASE-T4 and 100-BASET2. Fast Ethernet uses RJ-45 connectors and star topology. The CSMA/CD media access issued here. The minimum length between nodes is specified at 2.5 meters. With 1024 maximum number of connected segments possible, the IEEE802.3specification is used. The 100BASETX is a star shaped configuration similar to 10BASE T and uses two pairs of wires and Cat-5 cable to achieve the 100mbit/s speed. 100BaseTX requires category 5 two pair cables and the maximum distance of these is given at 100 meters. The100BaseT4 requires a category 3 cable with 4 pair and maximum distance of these cables is 100 meters. This system uses a Cat-3 cabling and uses all four pairs in the cable limited to half-duplex access methods. As now the popular Ethernet cabling is the cat-5 cabling, his is now considered obsolete. The final variety 100BASEFX is a 100mbit/Ethernet type that uses a multimode fibre. The maximum length specified here is 400 metres for half-duplex connections and 2 mms for full duplex connections to ensure that all collisions are detected.100BASEFX can thus use fibre optic to transmit up to 2000 meters and for this purpose it requires two strands of fibre optic cable. 100VG LAN is also another Ethernet variety that uses star topology, a series of interlinked hubs and RJ-45 connectors. In addition to Ethernet packets this implementation also supports the Token ring packets and has an IEEE 802.12 specification. It requires 4 pairs of category 3 cable wires and the maximum distance covered is 100 metres(Held, 1996). However with a category 5 cable 150 metres could be reached. Additionally the fibre optic can be used to transmit data up to 2000 metres. We next turn to Gigabit Ethernet Technology, which being a new and improved version of Ethernet altogether requires a separate section. Gigabit Ethernet Technology: Also known in its abbreviated form Gibe, the Gigabit Ethernet technology describes the implementation of Ethernet networking and transmitting ate speed of one or more than one Gigabit per second. Gigabit Ethernet is supported with the use of optical fibre and twisted pair cables and the physical layer standards in this category includes 1000BASET. 1 Gaps issued over a category 5 cable with copper cabling and 1000BASE SX issued to attain for short to medium distances over fibre. The first Gigabit Ethernet standard was set at the IEEE 802.3 standard in 1998.Its relatively recent launch suggests that the Gigabit Ethernet is the latest version of the Ethernet, which is the most popular and widely used computing network worldwide (Katsambis, 1998). The Gigabit speed of1000 mbps of raw bandwidth is 100 times faster than the original Ethernet version of 10mbps and its greatest advantages lies in the fact that it is compatible with existing Ethernets and uses the existingCSMA/CD and MAC protocols. Gigabit Ethernet competes directly with ATMas far as market competition is concerned. It is deployed in high capacity backbone network links and for small installations Gigabitspeed is not yet necessary. Gigabit Ethernet has been used in desktop technology in apple computers, Power MacG5, Apples power notebook and is also being built into Pentium boards. One of its desktop features includes professional video editing. Gigabit Ethernet has been outsmarted by the 10gigabit Ethernet technology, which is the fastest Ethernet standard that became fully operational in 2002. Introduction to Gigabit Ethernet Our discussion on Gigabit Ethernet began by providing a brief description of the Gigabit technologies and the main characteristic of this upgraded Ethernet variety. The transceiver used for Gigabit Ethernet is the GBIC also known as the Gigabit Interface Converter. Thebe measures 8.5 mm by 13.4 mm and has a depth of about 50mm. A hot swap standard electrical interface of a one Gigabit Ethernet port can support any physical media including copper to 100 km of single mode fibre. The standard Gigabit Ethernet system operates at 1000 Mbps speed of transfer of information (Norris, 2002). The 802.3z is the standard that describes the specifications for fibre optics for the 1000BASE-XGigabit Ethernet system. The 802.3ab standard describes specifications for the category 1000BASE-T twisted pair Gigabit Ethernet system. This rate the major two varieties of Gigabit Ethernet technologies used. The10 Gigabit Ethernet is a further up gradation and has speeds reaching10000 Mbps. According to Frazier, the chair of the Gigabit Task Force developing the Gigabit Ethernet technology has been challenging and hard work mainly because this new technology aimed at developing a standard that scales the operation of Ethernet networks to 1000 Mbps while retaining the known characteristics that are compatible with Ethernet and that have made Ethernet the dominant-local area network (LAN) technology. The Draft D3.1 of the P802.3z was approved in a letter ballot of thieve 802.3 working group and this was only possible when an approval rate of 75% was obtained from the working group. The protocol layers in802.3 standards are the areas that have been developed and modified in802.3z version (Riley and Braver, 1998). The 100BASE SX and 1000BASE Fibre optic transceiver specifications have already been highlighted here. The 1000BASE-SX specifications for short wavelength laser transceivers uses 62.5 micron fibre and supports multimode fibre optic links of up to 260 meters. The 50 micron fibre can be used to support multimode fibre optic links of up to 550 metres. The 1000BASE Supports installations at longer distances and uses higher cost components with 62.5 micron fibre used for 440 meters and 50 micron fibre on 550 meters. On a single mode fibre, up to 3 mms of fibre optic links are possible. One of the latest technologies 1000BASE-CX that supports copper cabling links of 25 metres, is included in the 802.3zspecification for transceiver technology. Frasier goes on to describe that the Gigabit Ethernet encompasses the new full-duplex Media Access Control (MAC) and the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC. The full duplex operation takes advantage of the contention free access and flexible topologies and the 802.3z used the CSMA/CD MAC to work at an extended range of 1000Mbps. This was done with the aid of a technique known as ‘carrier extension which was added to the CSMA/CD to overcome certain limitations of the algorithm that was based on the rule that the roundtrip messaging time between two workstations could not be higher than that required to transmit the smallest frame. To improve the throughput of Gigabit CSMA/CD LANs, frame bursting was introduced as an optional feature. In the early stages of deployment of the Gigabit Ethernet it is mainly being used to interconnect high performance switches, routers and servers in LAN backbones. The full duplex operating mode is suited for this type for application environment and is favoured over the CSMA/Chalk duplex mode. This also ensures that high performance desktop computers can take advantage of high peak bandwidths of repeating hubs that are cost effective. Frasiers claim also points to the fact that gigabit technology may be more compatible with full duplex rather than half-duplex modes of Ethernet operation. The 10 Gigabit Ethernet is full-duplex technology and the half-duplex access mode cannot be used for its purposes. T

Physics in Video Games :: physics video game computer

There are a few different physics engines that programmers use now for their games. There are 2 main physics engines that programmers use: Havok, and Math Engine. A Physics Engine is the code that game companies buy or Build to put in their code. The code is already written and they just have to implement the code in their program. The thing about Physics in video games is that none of it has to be realistic. Most of the physics in older games aren't close to being realistic for there were way too many equations the program would have to solve and it would slow it down. There are arguments that go on that unrealistic games are more fun, or realistic games are more fun. Video Games have been around for over thirty years now. A lot have changed in the way programs work. When they first came out Video Games weren't that powerful because the hardware couldn't support it. Now the possibilities are almost endless. Games have changed so much. From Games like Asteroids that was made in 1979. With Asteroids being only a small program with some computations going on. To current games like Half-life 2. With so many physics computations going on. They try to make this game the most realistic game. Out there. The current trend in video games is to make them more and more realistic. The more realistic they make the game. The more equations the program has to do, so the program is a lot bigger and needs a lot more power to do everything the game wants. There is a lot of lines of code in video games. There are teams of people who work on games now. Here is some example of how code is implemented into programs to make it look like you are jumping. I got this example from the web site http://www.gamedev.net/reference/articles/article694.asp this is pseudo-code that can be used for if you were having the character in the game jump straight up. Joe.postion.y = 0; (Or wherever floor is) Joe.velocity.y = 0; Joe.acceleration = 10; Joe.jumping = NO; Loop If (jump key is pressed) { Joe.velocity.y = 100; Joe.jumping = YES; } if (Joe.jumping == YES) /* Move Joe if we are jumping */ { Joe.velocity.y = Joe.velocity.y - Joe.acceleration Joe.

Foreign Direct Investment Essay

There has been a rise tide of Foreign Direct Investment (FDI) in the world’s economy. In the past decade businesses have become global due to the increased liberalization, changing capital markets and changing technology. With easy and effective communication systems investment of companies in foreign countries has been made easy. Foreign direct investment benefits the two countries, the host and the company investing. A high percentage of investment made through FDI involves building and fixtures or machinery and equipment. (www. oecd. org) Growing trade has caused an increase in FDI. Globalization has resulted to broadened markets that call for increased production of goods and services to match the demand. Production levels across the globe have also risen precipitating large corporations to invest in foreign countries. Corporations have the capital and resources to move their production bases to foreign countries. The service sector has also expanded. With technology advancement, skills and expertise have been developed. Corporations have adopted strategies that will increase active global investment and this is evident in the recent cross-border mergers. Strong corporate profitability has enabled corporates invests in the developing countries promoting FDI. Low interest rates and high real estate prices have also led to the underpinning of FDI. With the low US dollar value investors with other currencies gained the comparative advantage in investing in foreign countries. General macroeconomic growth in major economies has been reason behind increased FDI. (www. oecd. org) Countries prefer FDI as a strategy for entering foreign markets to exports and granting foreign entities the right to produce their products under license. Patent disclosure can occur when a local firm is given the product under license. It could give important information about invention and imitation could occur. The MNC’s could lose their workers to imitation product companies. Through FDI, the MNC’s can access larger market and can produce at reduced costs. These will ensure that their profitability levels are higher. FDI provide grounds under which future trade barriers can be countered. Exportation is constrained by transportation costs and trade barriers like tariffs and quotas. Licensing hinders the company from direct control and this creates loopholes that lead to reduced profitability. (Kreinin M. and Plummer M, 2002) Firms based in the same industry can undertake foreign direct investment at the same time when the local demand in the new area can support local supply. They can also locate such firms when there is price competition and cost pressure. Some areas have a comparative advantage over others and this makes them more favorable. They could be endowed with resources that the investors exploit using their technological and managerial capabilities. They reduce their costs as regional manufacturing plants serve regional markets. Political ideology influences government policy towards FDI. Some countries view MNC’s as tools of imperialist domination out to exploit their resources. MNC’s exploits the developing countries and creates dependency in terms of jobs and technology. They contribute to their continued backwardness, as they do not give back valuable output in return to the resources they exploit. Developing countries provide cheap labor and raw materials. Another view is the comparative advantage where countries benefit from FDI. This view is beneficial as host countries allow FDI and gain from it. They acquire products they do not produce and at lower costs. In this view countries produce what they can at least cost. Governments can restrict or promote FDI. If a government protects its domestic industries producing the same output as a foreign corporation, FDI will be discouraged. (Anderson K. and Blackhurst R, 1993) Governments can make policies on the location of multinational corporations (MNCs) that are favorable and that would increase FDI’S. They can also promote or put in place proper infrastructure like good transportation systems, education and transparency all of which works to encourage FDI. Peace and stability are very important factors in influencing FDI. Government must therefore ensure that they maintain law, and order political unrest deters FDI. Grants subsidies and tax concessions encourage inward FDI. There are economic and political agreements that favor regional economic integration like EU, NAFTA and MERCOSUR all of which have implications for business. Economic integration between nations could be though preferential trade area (PTA) where countries are offered tariff reduction and discrimination is reduced to member countries. Free trade area (FTA) could also be offered where countries eliminate tariffs between themselves but maintain their own external tariff on imports. Custom unions eliminate tariffs between themselves but set a common external tariff for instance the EU. Countries could also adopt a common market, economic union or monetary union level. (Kreinin M. and Plummer M, 2002) Economic arguments for economic integration. There is increased trade as countries produce what they have comparative advantage in. Foreign supply is reduced and trade diversity is promoted leading to economic growth. Member countries enjoy the economies of scale Political argument for economic integration is that it promotes peace and stability among member countries. Arguments against economic integration. Dumping of products can occur due to the eradication of barriers. Some countries tend to benefit more than others. Countries may feel as they are losing their sovereignty, which is their sense of pride. (Hoekman B. and Schiff M, 2002. ) The European Union is an economic union where member countries permit free movement of good, services and people and it uses a common currency it was initially known as the European Economic Community or common market. The North America Free Trade Agreement is a free trade agreement of Canada, US and Mexico. It eliminates barriers to trade and promotes fair competition and increased investment opportunities. MERCOSUR- comprises of Argentina, Brazil, Paraguay and Uruguay. It transformed from a custom union to a common market in 2006. The Asia pacific economic cooperation comprises 21 members. It was formed in 1989 through informal dialogue it promotes trade and investment and economic co-operation. The future of this great economic integration is promising. Businesses that are inherent in regional economic integration agreements will thrive if conditions in their regions are favorable. They will respond to the forces of demand and supply. Competition will be high and this will ensure that quality products are produced. References: Peter M. Suranovic. Trends and recent developments in FDI.

Modernism and Ball Turret Gunner Essay

In this poem it says at the start everything is gold or perfect then it goes away in the end which has loss of faith. It is rejecting Eden as a hero and who is flawed. â€Å"The Life You Save May Be Your Own† is modernism because a guy shows up, asks for work, takes the truck, and leaves the blind girl he married at a restaurant. This shows how a human mind can work in an evil way. He took the old ladies blind daughter that has never left home before and she loves her daughter and never wanted her to leave home but the strange man took her and left her all by herself. There is no hero in this story. The old lady didn’t do much to be a hero and neither did the blind girl. The strange man was the opposite of a hero, was greedy, and selfish by taking the car and leaving after he repaired it. â€Å" The Death of the Ball Turret Gunner† is a contemporary work because it comments on itself by saying, â€Å"When I died they washed me out of the turret with a hoses†. This poem has multiple meanings. One meaning is that he is in his mom’s stomach. The second meaning is him in the ball turret of a B-17 airplane. This is very personal. He got killed fighting for his country and they sprayed him out with a hose and didn’t give him the proper burial and respect. Night is also a contemporary work because it is very personal. He was put in a death camp for many years treated like crap because he was jewish. They barely fed the prisoners so they starved and died. They would also kill them with gas and work them to death. He talks about the past with no fear so everyone knows what happened in the past. The whole story is commenting on itself by explaining what happened at those death camps. Some of these stories and poems are modernist and contemporary works. Whether is in our past or present its still important. The works have many meanings and people enjoy reading them for the meaning of it not just to be entertained by the story but the true meaning of it. Poems and short stories have made a big impact in education and the way society is. Many people love poems and short stories but other people can hate them. I don’t like them my self but they still are important in education and for our future world.

How to Write a Diamante Poem

How to Write a Diamante Poem A diamante poem is a poem made of seven lines of words that are arranged in a special diamond-like form. The word diamante is pronounced DEE - UH - MAHN - TAY; it is an Italian word meaning â€Å"diamond.† This type of poem does not contain rhyming words. There are two basic types of diamante poems: an antonym diamante and a synonym diamante.   Antonym Diamante Poem The first step to writing an antonym diamante poem is to think of two nouns that have opposite meanings. Because a diamante poem is diamond-like in form, it must begin and end with single words that form the top and bottom. In the antonym form, those words will have the opposite meaning. Your job as a writer is to transition from the first noun to the opposite noun in your descriptive words. Synonym Diamante Poem The synonym diamante takes the same form as the antonym diamante, but the first and last words should have the same or similar meaning. Diamante Poems Follow a Specific Formula Line one: NounLine two: Two adjectives that describe the noun in line oneLine three: Three verbs that end with â€Å"ing† and describe the noun in line oneLine four: Four nouns- the first two must relate to the noun in line one and the second two will relate to the noun in line sevenLine five: Three verbs that end with â€Å"ing and describe the noun in line sevenLine six: Two adjectives that describe the noun in line sevenLine seven: Noun that is opposite in meaning to line one (antonym diamante) or the same in meaning (synonym diamante) as the noun in line one The first line of this poem will contain a noun (person, place, or thing) that represents the main topic of your poem. As an example, we will use the noun â€Å"smile.† Two words that describe a smile are happy and warm. Those words will form the second line in this example.   Three verbs that end with â€Å"-ing† and describe a smile are: welcoming, inspiring, and soothing. The center line of the diamante poem is the â€Å"transition† line. It will contain two words (the first two) that relate to the noun in line one and two words (the second two) that relate to the noun that you will write in line seven. Again, the noun in line seven will be the opposite of the noun in line one.   Line five will be similar to line three: it will contain three verbs ending in â€Å"-ing† that describe the noun you will put at the end of your poem. In this example, the final noun is â€Å"frown,† because it is the opposite of â€Å"smile.† The words in our example poem are disturbing, deterring, depressing. Line six is similar to line two, and it will contain two adjectives that describe â€Å"frown.† In this example, our words are sad and unwelcome. Line seven contains the word that represents the opposite of our subject. In this example, the opposite word is â€Å"frown.† For Inspiration: Antonym Pairs   Mountain and valleyQuestion and answerCurve and lineCourage and cowardiceHero and cowardHunger and thirstKing and queenPeace and warSun and moonBlack and whiteFire and waterFriend and foe For Inspiration: Synonym Pairs Heat and warmthNoise and soundSnake and serpentFear and frightEmployer and bossHappiness and joyGloom and despairSorrow and sadnessBlanket and coverletStory and taleLaugh and giggleCoat and jacketClock and timepieceTest and exam

Geography of Vancouver, British Columbia, Canada

Geography of Vancouver, British Columbia, Canada Vancouver is the largest city in the Canadian province of British Columbia and is the third largest in Canada. As of 2006, Vancouvers population was 578,000 but its Census Metropolitan Area surpassed two million. Vancouvers residents (like those in many large Canadian cities) are ethnically diverse and over 50% are not native English speakers. Location The City of Vancouver is located on the British Columbias west coast, adjacent to the Strait of Georgia and across that waterway from Vancouver Island. It is also north of the Fraser River and lies mostly on the western part of the Burrard Peninsula. The city of Vancouver is well-known as one of the worlds most livable cities but it is also one of the most expensive in Canada and North America. Vancouver has also hosted many international events and most recently, it has gained worldwide attention because it and nearby Whistler hosted the 2010 Winter Olympic Games. What to Know About Vancouver The following is a list of the most important things to know about Vancouver, British Columbia: The City of Vancouver is named after George Vancouver - a British captain who explored Burrard Inlet in 1792.Vancouver is one of Canadas youngest cities and the first European settlement was not until 1862 when McLeerys Farm was established on the Fraser River. It is believed, however, that aboriginal people lived in the Vancouver region from at least 8,000-10,000 years ago.Vancouver officially incorporated on April 6, 1886, after Canadas first transcontinental railroad reached the region. Shortly thereafter, the nearly the entire city was destroyed when the Great Vancouver Fire broke out on June 13, 1886. The city quickly rebuilt though and by 1911, it had a population of 100,000.Today, Vancouver is one of the most densely populated cities in North America after New York City and San Francisco, California with around 13,817 people per square mile (5,335 people per sq km) as of 2006. This is a direct result of urban planning focused on high-rise residential and mixed-use development as opposed to urban sprawl. Vancouvers urban planning practice originated in the late 1950s and is known in the planning world as Vancouverism. Because of Vancouverism and a lack of large amounts of urban sprawl as seen in other large North American cities, Vancouver has been able to maintain a large population and also a large amount of open space. Within this open land is Stanley Park, one of the largest urban parks in North America at around 1,001 acres (405 hectares).Vancouvers climate is considered oceanic or marine west coast and its summer months are dry. The average July high temperature is 71Â °F (21Â °C). Winters in Vancouver are usually rainy and the average low temperature in January is 33Â °F (0.5Â °C).The City of Vancouver has a total area of 44 square miles (114 sq km) and consists of both flat and hilly terrain. The North Shore Mountains are located near the city and dominate much of its cityscape, but on clear days, Mount Baker in Washington, Vancouver Island, and Bowen Island to the northeast can all be seen. In the early days of its growth, Vancouvers economy was based around logging and sawmills which were established beginning in 1867. Although forestry is still Vancouvers largest industry today, the city is also home to the Port Metro Vancouver, which is the fourth largest port based on tonnage in North America. Vancouvers second largest industry is tourism because it is a well-known urban center worldwide. What Its Known For Vancouver is nicknamed Hollywood North because it is the third largest film production center in North America following Los Angeles and New York City. The Vancouver International Film Festival takes place annually each September. Music and visual arts are also common in the city. Vancouver also has another nickname of city of neighborhoods as much of it is divided into different and ethnically diverse neighborhoods. English, Scottish, and Irish people were Vancouvers largest ethnic groups in the past, but today, there is a large Chinese-speaking community in the city. Little Italy, Greektown, Japantown and the Punjabi Market are other ethnic neighborhoods in Vancouver. To learn more about Vancouver, visit the citys official website. Sources: Wikipedia.

Promoting Rights of Children in Ghana Essay Example | Topics and Well Written Essays - 1000 words

Promoting Rights of Children in Ghana - Essay Example Ecological systems theory The ecology of human development theory as propounded by Bronfenbrenner has defined as the † mutual accommodation between an active, growing human being and the changing properties of the immediate settings in which the developing individual person lives†. In accordance with this theory, the child is envisaged as developing within a complex system of relationships affected by multiple levels of the environment surrounding the child. In Ghana, this has been complicated by HIV/AIDS,children are experiencing death pf parents at an early age and are taken care of by other foster parents. Attachment theory Development and emotional functioning of children occurs in a context of relationships (Bronfenbrenner 1979,Osofsky 2004). Children depend on their caretakers as sources of protection and safety. Aims and research questions: The aims of our research and the questions that we want to answer through the research are as follows: †¢ Are NGOs actually helping children to progress in any way? †¢ In what ways are children being helped? †¢ What are the aspects of life of the children that are affected by the NGOs? †¢ To prove that NGOs are needed not only for orphan kids but also for kids who have parents taking care of them. †¢ To prove NGO workers and volunteers are sometimes more effective in child welfare than the Government or police. Background Child welfare is an important issue in any country. In Ghana, this responsibility is shouldered by the nuclear or extended family of a child. Nuclear family include the parents, while Extended family includes, the grandparents, uncle, aunty, or any other relative. However, poverty, HIV, child abuse and child labour is affecting families, and eventually affecting the children. Our concern is the role that is played by the international and local N.G.Os in these children's life. Methodology While the two common types of research methods are the Qualitative and Quantitative research methods, I would be using the mixed method procedure that is a mix of both qualitative and quantitative research methods. It is a relatively new research approach in the social and human sciences. It is unique because it included the advantages of both the qualitative and quantitative methods. While quantitative methods asks how many, and qualitative asks what and how, mixed methods asks why. The mixed method research has both thematic and numerous One of its strength is also that its validity and reliability standards. It has both closed ended measures and open observations. The study used would be Qualitative methods of data collection and data analysis , which will be followed by quantitative methods of data collection and analysis. The data collection for qualitative methods were INTERACTIVE INTERVIEWING The aim of the interview is to find out the participant's perception, hence their views should be unbiased. Interviews can also be a group interviews. The answers should preferably not be, YES or NO, asthat makes details unachievable. The researcher should choose an environment thatmakes the participants comfortable. PARTICIPANT OBSERVATION The researcher should monitor observation and recordpersonal bias of the participant. The researcher himself should be very neutral and not haveany prejudice while observing participant. FOCUS GROUP The focus group session is, indeed, an interview (Patton, 1990) not a discussion group, problem-solving session, or decision-making group. Comprises of both

Should tablet computer replace the traditional Textbook Essay

Should tablet computer replace the traditional Textbook - Essay Example It is time globalization provided something positive to one of the internationally universal sector, academic (Reiss, 2013). Computer tablets are built to increase the efficiency of individual users. With respect to the amount of positive work they can accomplish, it is clear that their prices and usefulness provide a reasonable cost benefit tradeoff. On the other hand, the cumulative cost of all the textbooks needed for completing a course is high which makes the use of e-books cheaper. Although piracy is a crime in the US, the use of computer tablets enables different members of the academic sector to share the academic resources they have. For online courses, tuition fees paid to institutions allows students to have access to online library. With computer tablet, it is economical to access the virtual libraries rather than buying from online vendors (Rock, 2014). Being a student means being able to take notes, solve math problems, erase some errors from written text, draw in art class, and perform complex statistical analysis as coursework. All these activities require the student to have pens, pencils, calculators, and computers. Using a computer tablet combines all these factors together ensuring that the student spends less. Another reason as to why traditional textbooks should be replaced with computer tablets is because the production of textbooks involves the destruction of vegetation cover which suppresses the economy even further. Carrying heavy back packs has been associated with back issues such as injuries and lifelong complications. Carrying textbooks to and from school is an activity that largely contributes to back issues. However, the use of computer tablets resolves the issues associated with carrying heavy textbooks. Due to the small size and standard weight of 1 to 2 pounds makes tablet computers suitable for cutting back on back health issues (Tablets-Textbooks, 2014). In

Importance of Theory Research Paper Example | Topics and Well Written Essays - 1250 words

Importance of Theory - Research Paper Example This paper will explore Nightingale’s theory which is based on systems, interactions and development, and to relate it to the nursing practice today. On a given day nurses utilize several nursing theories. Nursing theories are basic concepts that define the nursing practice and attempts to describe and explain what and why nurses do what they do (nursing). Nursing theory is important in differentiating nursing from other disciplines as its main purpose is to describe, explain, predict, and control desired nursing practice outcomes. These theories applied daily by nurses are guidance to how a nurse gives treatment to a patient, how nurses perform their tasks, complete their assessments, and establish interventions. By studying nursing theory, students are able to start thinking critically. For example, nursing theory can be termed as the foundation of good nursing and clinical practice. Even when building a house the foundation is the most important; a strong foundation means a long lasting house. Similarly when the foundation is cracked, the structure (nursing practice) is weakened. Therefore, having a good comprehension of the n ursing theories from the nursing education level topped up with intuition and compassion makes a strong nurse. Nursing theory is the foundation of nursing research which in return develops the nursing practice. It is essential in health care advancement, which allows patients to get the best possible nursing care. As medicine is trying to make a more multidisciplinary approach to health care, nursing has to aim at establishing a exceptional body of knowledge. For example, nurses are gradually increasing their practice scope by performing tasks that were previously carried out by doctors. It is therefore important for theory to define the position of nurses and their roles (Colley, 2003). By giving them this sense of identity,

Water Pollution of Duwamish River (Seattle) Essay

Water Pollution of Duwamish River (Seattle) - Essay Example For instance, this pollution has resulted to a decrease in the number of Salmon fish. This is because the River Duwamish is the major breeding and rearing ground of the Salmon fish, and the chemical pollution that occurs in the river, has resulted to the depletion of oxygen, making it impossible for these fish to survive. Human beings are affected because they cannot consume fish from this river. Consumption of food substance that emanate from this river are polluted, hence it is a danger to the life of human beings. Hence, there is a need of initiating measures aimed at conserving and protecting the river from pollutants. Goel (7) begins his study by the definition of water pollution. He defines water pollution as negative changes in the quality of water bodies, making it harmful for use by any living organisms (Goel, 9). There are different types of water pollution. Some of these include nutrients, surface, oxygen depleting, ground water, microbiological and chemical water pollution. All these have a negative effect on marine animals, as well as on human beings who are using the polluted waters under consideration. For instance, one of the major effects of water pollution is that it leads to the death of marine animals. Crabs, seas gulls, dolphins, and other marine animals are always killed by contaminated water. Water pollution also has the capability of disrupting the natural food chain. Chemical pollutants like lead are always consumed by tiny sea animals. Later on, these tiny animals are consumed by fish, which in turn is consumed by human beings. This can lead to an aspect referred to as food p oisoning. Water pollution affects the entire world, and therefore, there is a need of coming up with a water resource policy, that can help in the reduction of water pollution. Furthermore, there is a suggestion and proof that water pollution is one of the leading causes of deaths in the world (Hauser-Davis, Reinaldo and Roberta,

Although Japan has been influenced a lot by western culture, most people still stick to the conservative concept-female should stay at home, not go outside to work. In 2007, Japans GEM(United Nations Development Programs Gender Empowerment Measure, which gauges equality by tracking womans participation in politics and business) was ranked 54th out of 93 countries. Japanese should be open-minded and encourage female to work. If female work, their talent and education can be best made use of. What is more, since males and females are complementary in many aspects, their cooperations with males can propel economic development more effectively. Second is responsibility. According to a survey conducted by Japanese Youth Institute, about 59. 7% American teenagers and 46. 9% Chinese teenagers can be responsible for themselves, but for Japanese teenagers, only 25. %. Because of the lack of responsibility, they do not care about anything, no matter their families or their country; when they meet problems, what they think is not how to solve them, but how to put off their liabilities. We can imagine what awful situation Japan will be if one day this generation takes over it. How can the people without responsibilities be able to develop a country? Therefore responsibility is a very important value if Japan wants to improve. The third one is humor. As we all know, Japan is a country with the highest suicide rate. There are very severe competitions in Japan and Japanese live in a fast-tempo lifestyle. Theyre under much pressure everyday and these pressure lead to suicide. So how to relieve pressure is very crucial. According to scientific research, humor can help people relax themselves, relieve their life pressures and keep their mental healthy. In short, humor can make people have a positive life attitude. Only when people are happy, can they contribute to countrys development. So humor is another value which would help make Japan a better country. When Japanese are more open-minded, they can improve themselves and develop their country; when more Japanese have responsibilities, their society can be more harmonious; when Japanese have more humor, their lives can be more interesting. All in all, if Japan wants to become a better country, open-minded, responsibility and humor would help make it.

The four levels of measurements

The four levels of measurements The four levels of measurements 1. Explain briefly how you would use number properties to describe the four levels of measurements. Answer: Measurements can be classified into four different types of scales. These are: Nominal Ordinal Interval Ratio Nominal scale: Nominal measurement consists of assigning items to groups or categories. No quantitative information is conveyed and no ordering of the items is implied. Religious preference, race, and sex are all examples of nominal scales. Frequency distributions are usually used to analyze data measured on a nominal scale. Categorical data and numbers that are simply used as identifiers or names represent a nominal scale of measurement. Numbers on the back of a baseball jersey and social security number are examples of nominal data. At the nominal scale, i.e., for a nominal category, one uses labels; for example, rocks can be generally categorized as igneous, sedimentary and metamorphic. For this scale some valid operations are equivalence and set membership. Nominal measures offer names or labels for certain characteristics. The central tendency of a nominal attribute is given by its mode; neither the mean nor the median can be defined. Ordinal scale: An ordinal scale is a measurement scale that assigns values to objects based on their ranking with respect to one another. For example, a doctor might use a scale of 0-10 to indicate degree of improvement in some condition, from 0 (no improvement) to 10 (disappearance of the condition). An ordinal scale of measurement represents an ordered series of relationships or rank order. Individuals competing in a contest may be fortunate to achieve first, second, or third place. First, second, and third place represent ordinal data. In this scale type, the numbers assigned to objects or events represent the rank order (1st, 2nd, 3rd etc.) of the entities assessed. An example of ordinal measurement is the results of a horse race, which say only which horses arrived first, second, third, etc. but include no information about times.: The central tendency of an ordinal attribute can be represented by its mode or its median, but the mean cannot be defined. Interval scale: Quantitative attributes are all measurable on interval scales, as any difference between the levels of an attribute can be multiplied by any real number to exceed or equal another difference. A highly familiar example of interval scale measurement is temperature with the Celsius scale. In this particular scale, the unit of measurement is 1/100 of the difference between the melting temperature and the boiling temperature of water at atmospheric pressure. The zero point on an interval scale is arbitrary; and negative values can be used. The formal mathematical term is an affine space (in this case an affine line). Variables measured at the interval level are called interval variables or sometimes scaled variables as they have units of measurement. Ratios between numbers on the scale are not meaningful, so operations such as multiplication and division cannot be carried out directly. But ratios of differences can be expressed; for example, one difference can be twice another. The central tendency of a variable measured at the interval level can be represented by its mode, its median, or its arithmetic mean. Statistical dispersion can be measured in most of the usual ways, which just involved differences or averaging, such as range, inter quartile range, and standard deviation. Since one cannot divide, one cannot define measures that require a ratio, such as studentized range or coefficient of variation. More subtly, while one can define moments about the origin, only central moments are useful, since the choice of origin is arbitrary and not meaningful. One can define standardized moments, since ratios of differences are meaningful, but one cannot define coefficient of variation, since the mean is a moment about the origin, unlike the standard deviation, which is (the square root of) a central moment Ratio scale: The ratio scale of measurement is the most informative scale. It is an interval scale with the additional property that its zero position indicates the absence of the quantity being measured. You can think of a ratio scale as the three earlier scales rolled up in one. The ratio scale of measurement is similar to the interval scale in that it also represents quantity and has equality of units. However, this scale also has an absolute zero (no numbers exist below the zero). A ratio scale is a measurement scale in which a certain distance along the scale means the same thing no matter where on the scale you are, and where 0 on the scale represents the absence of the thing being measured. Most measurement in the physical sciences and engineering is done on ratio scales. Mass, length, time, plane angle, energy and electric charge are examples of physical measures that are ratio scales. The scale type takes its name from the fact that measurement is the estimation of the ratio between a magnitude of a continuous quantity and a unit magnitude of the same kind. Informally, the distinguishing feature of a ratio scale is the possession of a non-arbitrary zero value. For example, the Kelvin temperature scale has a non-arbitrary zero point of absolute zero, which is denoted 0K and is equal to -273.15 degrees Celsius. This zero point is non arbitrary as the particles that compose matter at this temperature have zero kinetic energy. All statistical measures can be used for a variable measured at the ratio level, as all necessary mathematical operations are defined. The central tendency of a variable measured at the ratio level can be represented by, in addition to its mode, its median, or its arithmetic mean, also its geometric mean or harmonic mean. In addition to the measures of statistical dispersion defined for interval variables, such as range and standard deviation, for ratio variables one can also define measures that require a ratio, such as studentized range or coefficient of variation. 2. Define the terms direct measurement and indirect measurement. Describe briefly how you would make profit of indirect measurement in psychological traits. Answer: There are 2 types of measurement techniques are developed in order to measure quality or characteristics of attributes. First one is quantitative and second is qualitative. Quantitative can be measured directly and qualitative can not be measured directly. The height and weight of a person can be measured directly with scales in feet/meter, kilogram. But qualitative variable cannot be measured with scales such as feet, meter, kilogram etc. For example, Kindness, love and intelligence of a person can not be measured directly. Indirect measurement can be used for these cases. To measure this type of cases different indirect measures like answer to questions, IQ tests can be used. Indirect measurements are mostly used in social science. Richness, happiness, good life, poverty etc can be measured with the support of different indirect indicators. In order to measure psychological traits we use behaviors as a basis for measurement. Qualities of an individual can be measured indirectly through psychological testing by developing indicators. In standard psychological test we develop the set of standard as questionnaire or guidance fro scoring the attributes or traits. We largely use objective types of question and interpret according to the guidance of answering. Human behavior can not measure as physical measurement like height, weight. The qualitative aspects like perception, emotion, retention etc can be measured through indirect measurement, which is based on some pre-defined set of standards. 3. What will happen if you use ordinary measurement as though they were interval or ratio measurement? Ordinary data is non parametric data and interval and ratio are parametric data. Therefore we dont use ordinary measurement if the data are in interval or ratio measurement. They differ from each other. To ensure measurement more reliable, selection of appropriate statistical tools according to the nature of data is important. If we use interval/ratio measurement when the data are ordinal scales it may leads false decision. 4. Which method census or sampling do you prefer the most for describing the reality of Nepali classroom teaching learning? Explain in brief. Answer: Sampling method is more applicable than the census method for describing the reality of Nepali classroom teaching learning. To study about promotion, failure and drop out rate, census method can be used. However for the reality presentation, census method can not be convenient. Through the census method each and every unit of the population can be taken into consideration. But it will be highly time and money consuming. Sampling method will make all process faster with less cost. While taking the sample size there is more important of inclusion and representation in the sampling i.e. ethnic group, caste, religion, , geographic zone, and gender, etc. Through educational perspective different grades, private and public school/college suppose to be included. The sample size should more representatives. 5. in a group of 50 children, the 8 children who took longer than 3 hours to complete a performance test in sent-up test were marked as DNC (did not complete). In computing a measure of central tendency for this distribution of scores, what measure we should use and why? Median can be used in computing a measure of central tendency for the distribution of score as mentioned in the question. Median is not affected by extreme values. Arithmetic mean is affected by extreme values. As Median is the positional average, we can get the correct value of central tendency. 6. Give some examples where you need geometric and harmonic mean. Give geometrical interpretation of A.M., G.M. and H.M. Answer: Geometric Mean (G.M): Geometric Mean (G.M) is widely used in averaging ratios and percentages and is computing average rates of increase or decrease. It is also advantageously used in the construction of index numbers. G.M. gives equal weights to equal ratios of change. It is also used to compute the average rate of growth or reduction of population or average increase or decrease of production, profit, sales etc. When we require to give more weight to smaller items and smaller weight to larger (e.g. Social and economic problems) G.M can be used. Harmonic Mean (H.M.): Harmonic Mean (H.M.) is used in computing the averages relating to the rates and ratios such as velocity speed etc., where time factor is the variable. It also can be used for making Human Development Indicator (HDI). Geometrical interpretation of A.M., G.M., and H.M. Let AD = a, DB = b Then represents the radius of the semi circle. Hence radius OP = , which gives the value of A.M. Similarly radius OQ = , Now OD = b = Now DQ2 = OQ2 OD2 = { }2 { }2 = ab Hence, DQ = , which represents G.M. Now, in the right angled triangle ODM, DM2 = OD2 OM2 And in right angled triangle DMQ, DM2 = DQ2 MQ2 Hence, OD2 OM2 = DQ2 MQ2 Here, OQ = . Let OM = x, then MQ = x {}2 x2 = ab { x}2 For solving, x = Hence, MQ = = , which represents H.M. From above it is clear that OP = A.M., DQ = G.M. MQ = H.M. From the figure, it is clear that OP > DQ > MQ. Hence, we can say that A.M. > G.M. > H.M.H 7. Give geometrical meaning of the formula used for Median and Mode for grouped data. Answer.: Geometrical meaning of the formula used for Median: Let consider the following continuous frequency distribution, (x1 < x2 < xn+1). Class interval: x1 x2 , x2 x3, . xk xk+1, . xn xn+1 Frequency: f1 f2 fk fn The cumulative frequency distribution is given by: Class interval: x1 x2 , x2 x3, . xk xk+1, . xn xn+1 frequency : F1 F2 Fk Fn Where, Fi = f1 + f2 + ..+ fi-1. The class xk xk+1 is the median class if and only if Fk-1 < N/2 < Fk. Now, if we assume that the variate values are uniformly distributed over the median class which implies that the ogive is a straight line in the median class, then we get from the fig.1, tan = i.e. or or, = Where is the frequency and h the magnitude of the median class. Hence, BS = Hence, Median = OT = OP + PT = OP + BS = l + This is the required formula. Geometrical meaning of the formula used for Median: Let us consider the continuous frequency distribution: Class interval : x1 x2 , x2 x3, . xk xk+1, . xn xn+1 frequency : f1 f2 fk fn If fk is the maximum of all the frequencies, then the modal class is (xk xk-1). Let us further consider a portion of the histogram, namely, the rectangle erected on the modal class and the two adjacent classes. The modal is the value of x for which the frequency curve has a maxima. Let the modal point be Q (fig. 2) From the figure, we have tanß = and tana = or, or, , where h is the magnitude of the model class. Thus solving for LM, we get LM = Hence, Mode = OQ = OP + PQ = OP + LM = l + 8. Squaring deviations and then taking squares seems to be useless. Why do we use square? Answer: Squaring deviation and then taking squares seems to be useless however actually it has certain meaning like the squaring of the deviations (x-x) removes the drawbacks of ignoring signs of the deviations in computation of mean deviation. Taking the sign into consideration we obtain positive values always when squared. But squaring gives aunit that isthe square of theunit the quantity is measured in. This step provides it suitable for further mathematical treatment. 9. Study the following summary statistics of the scores of two graders VI and VII. Now give your answer to the following questions and give figures to support your answers. a. Which class had the larger number of pupils? Answer: Grade VI had larger number of pupils. b. Which class on the average had the higher scores? Answer: Grade VII on the average had the higher scores. c. In which class were the scores more scattered? (Given four different statistics to show the difference in scatter.) Answer: For Grade VI, the scores are more scattered. The four different measures to show the difference in scatter ness are as follows: Interquartile range Coefficient of S.D. Coefficient of M.D. from mean Coefficient of variation 9. Are the distributions of scores about the mean symmetrical? What is your evidence? If not, which class has high scores not balanced by similar low scores? The distribution of scores about the mean in both classes are not symmetrical as we can find Mean = Median = Mode is not satisfied for both the grades. In grade VI, since Mean < Median Median > Mode, it is positively skewed. That is there is greater variation towards the higher values of the variables. 10. Take one distributed data grouped into different frequencies and calculate different measure of central tendencies (Arithmetic mean, Median, and mode) and measures of dispersion (Q.D., MD, and SD). Give your judgments about your data concerning to symmetry. Answer: Suppose, the weights of 50 students of a class are classified below. For Mean; Mean = A + = 65- = 64.87 Hence, Mean =64.87 For Median; Hence, Median lies in the class 60-70 Median = = 60+=66.2 Hence, Median=66.2 For Mode; Since maximum frequency occurs at two classes, so the given distribution is a bimodal distribution. So, Mode =3 median-2 mean =3*66.87-2*64.87 =198.6-129.74=68.86 Hence, Mode=68.86 For Quartile Deviation; Position of Q1= Hence First Quartile (Q1) lies in the interval 50-60 Now, Q1 = 50+ Hence, First Quartile (Q1)= 57.28 Position of Q3= Hence Third Quartile (Q3) lies in the interval 70-80 Again, Q3 = =70+ =73.62 Now, QD= ==8.17 Hence, Quartile Deviation (QD) = 8.17 For Mean Deviations; Mean deviation from mean Calculation of Standard Deviations Now, N = 75, ÃŽ £fd = -1 ÃŽ £fd2 = 89 = = =1.08*10 =10.81 To identify Symmetry Here, Mean = 64.87 Median = 66.2 Mode = 68.86 Hence, the curve is not symmetrical. Calculation of Skewness Sk = is negative skewed.

Critiquing and Repairing Free Trade under NAFTA :: Global Political Politics Essays

Critiquing and Repairing Free Trade under NAFTA On January 1, 1994, the North American Free Trade Agreement (NAFTA), the free trade policy linking the economies of Canada, the United States, and Mexico was officially implemented. Over the past decade, the policy has evoked a firestorm of debate involving neoliberal advocates, mercantilist critics, and radical critics, all of whom analyze and critique NAFTA in an effort to determine the success of free trade. Since NAFTA policies are evaluated by political economists with differing ideologies, the success of NAFTA’s first decade remains in question. After a decade, which economists herald NAFTA as a success and who disregards it as a failure? Which set of economic and political standards should be used to evaluate free trade? And ultimately, what policies should be implemeted in NAFTA’s second decade? Since there is little agreement on the future of NAFTA, it is wise to look to the past if we are to determine where the future may lead. By understanding the conflicting arguments inherent in debate on free trade, then perhaps we can better establish priorities and suggestions for policy reform in NAFTA’s second decade. Essentially, all disagreements in political economics stem from three theoretical perspectives: neoliberalsim, mercantilism, and radicalism. The three theories emphasize divergent characteristics associated with economic vitality: neoliberals emphasize market efficiency, mercantilists defend state sovereignty, and radicals value social justice. History has taught us that these theories regularly contradict each other and ultimately result in policy conflicts evidenced by countless case studies. Free trade and economic growth is a pressing concern for political economists, suggesting that little common ground can be found among the three theories. The first of the three political economy scholars are neoliberals, who reject government intervention in the economy through protectionist policies such as tariffs, subsidies, and quotas; rather, their focus is on overall economic growth as evidenced by increases in gross domestic product. Neoliberal advocates expected NAFTA to produce an increase in exports of goods and services, create additional jobs, expand foreign investment, and spur overall economic growth. These four expectations of free trade policy serve as a means of evaluation for neoliberals. Neoliberal standards of success are easy to understand: if NAFTA has produced more goods, jobs, investment, and overall profits, then NAFTA should be heralded as a success.

black and chinese americans :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚   In the present day, people view America as a land where everyone can be seen equal to one another, but this was not always the case. In the 1800s black and Chinese Americans went through a ruthless period of discrimination, due to the white man’s ignorance. Even though the Chinese and blacks were singled out they both were treated differently but also had many similarities.   Ã‚  Ã‚  Ã‚  Ã‚  Harsh treatment, long hours, and extremely low wages were only a small part of the brutal-ness both races faced. The Chinese men came to America hoping to provide a better life for theirs families back in China. Most of them received jobs working for the corrupted railroad companies. They faced horrific working conditions, which some died from, low wages, and long hours. The Chinese men wasted years of their lives and sacrificed seeing their families so that they can make enough money to support them.   Ã‚  Ã‚  Ã‚  Ã‚  The blacks have faced similar conditions to the Chinese men. They too worked long hours and earned very low pay. Many of the blacks became sharecroppers once they were emancipated. Sharecroppers were tenant farmers who gave a share of the crops raised to the landlord in lieu of rent. These landlords were cruel and took a good portion of the crops grown by the black farmers. Whatever the landlords did not take was left for farmer and his family, which was not much. They had to survive through the winter with the limited supply. Both the Chinese and blacks could not do anything about the working conditions due to the fact they could not unite and form labor unions.   Ã‚  Ã‚  Ã‚  Ã‚  Though both Chinese and blacks faced many similarities they also had differences. The blacks have lived in American for generations while the Chinese were just starting to immigrate. Blacks were forced to come to America to be slaves as opposed to the Chinese coming here by their own free will. Also the America did not allow Chinese women into the country due to the fear of an even more rapid rate of increase in the Chinese population, while black women were in the country and had a prominent role in their family lives. Another difference between the two races was that the black Americans had families in the country and the Chinese left their families back in China. Another differentiation was that once the blacks were emancipated most stayed in America while a good number of the Chinese left to go back home.

American Culture and Women

The fact that American culture positively recognizes single motherhood and not single fatherhood is wrong and in my opinion untrue. Single mothers do not in any circumstance have an advantage over single fathers. Especially in today’s society, when there are a lot of stay-at-home fathers, due to the economic recession, and the divorce rate being higher than ever this gives fathers an equal opportunity to be the primary caregiver in the child’s upbringing.Most Americans positively recognize single motherhood and not single fatherhood. The question I would ask those people is, â€Å"Have you been raised by a single father? † Most likely the answer will be no. Those individuals probably were raised in a dual parent environment and don’t even know what it’s like to be raised by a single parent. I would then proceed to tell them that single fathers have the same ability as mothers to raise quality sons or daughters. There truly is no so called â€Å"adv antage† when it comes to parenting.There is a wide range of skills required in raising a child, from codling them as small infants to disciplining them as adolescents. Either parent, mother or father, can posses those skills, who’s to say a mother is better at coddling and a father is better at disciplining. Single parents, whether a mother or a father can have the qualities needed to raise a confident, well-mannered, and respectful child. Neither one has an advantage over the other, they are both equal. If either one is willing to put the effort into being a parent then they should be successful.
