The Leeuwin Current

The Leeuwin Current is a warm ocean current that flows towards the south around the Western Australian coast and turns towards the east passing through Cape Leeuwin. It continues towards the Great Australian Bight influencing as far as Tasmania. It was discovered a hundred years ago when an investigation of the marine life of the Abrolhos Islands was conducted by William Saville-Kent. It was alleged that there was a warm current flowing towards the south off Western Australia instead of the anticipated cool current that was going towards the north in the bounds of southern Africa and South America. This supposition was based on his observations of warm waters and tropical marine flora and fauna around the Abrolhos Islands. It was only during the dawn of the satellite technology in 1970s that the existence of the southwards-flowing current was finally confirmed. It was then named the Leeuwin Current by George Cresswell and Terry Golding, with its name coming from a merchant ship called Leeuwin, which meant Lioness. The Leeuwin current’s strength varied all through out the year. Its current was strongest during autumn and winter, on the months of April to October, because the opposing winds are weakest. The weakest Leeuwin current’s strength, on the other hand, is weakest during November to March. It is during this season when there are strong winds blowing towards the north opposing the southwards flow of the current. The most productive fisheries are due to the Leeuwin current’s rush of cool waters rich with nutrients. Here are the contributions that the Leeuwin current brought to the marine life and the aquatic environment that it flows through. The existence of true corals at the Abrolhos Islands and the transport of tropical marine species at the west coast and onto the Great Australian Bight are due to this current. This is because the Leeuwin Current causes the continental shelf waters of Western Australia to be warmer in winter than the regions equivalent of that in southern Africa and Chile during summer. The Houtman Abrolhos Islands which is near the edge of the continental shift off of Geraldton, is the southernmost true building corals in the Indian Ocean partly due to the effect of the nutrient-rich tropical waters of the Leeuwin current. The Leeuwin current is seldom to flow around the east of Rottnest but it oftentimes pass by its western and southwestern areas thereby also influencing the flora and fauna there. The coastal waters are relatively nutrient-poor and the fisheries are correspondingly different due to the tropical Leeuwin Current, thus we can infer that the current has a very important impact on both the climate and the marine ecosystem of Western Australia. It is also accountable for the availability of tropical marine organisms at the west and south coasts, as much far south than it could be expected. As a sample, the Leeuwin current was a major contributor to the southern bluefin tuna, the western rock lobster and a number of Australia’s coastal commercial fisheries. As it was seen by collective investigative reports done by CSIRO and the Fisheries Western Australia that spanned for the past 30 years, it was confirmed that there was a link between ocean circulation and lobster recruitment. During late winter and early spring, the puerulus, or the small rock lobsters, are carried by ocean currents back to the continental shelf and inshore coastal regions. Studies had shown that the settlement of these small rock lobsters were closely related with the changes in the flow strength of the Leeuwin Current, which is also linked with the occurrences of El Nino – Southern Oscillation (ENSO) events and westerly winds. It was discovered that puerulus settlement was poor during the El Nino years, when the Leeuwin Current tends to be weak. Also, during the La Nina years, the Current tends to flow more strongly and the rock lobsters settlement was much greater as was measured by satellite sensors. The results simply showed that larger counter-clockwise eddies help larvae settle off the south western Australia, instead of being swept away towards the south. Other species that the WA Fisheries marine biologists were able to link to the strength of the Leeuwin current was that of the pilchards (sardines) on the south coast region near Albany. Also, according to data on fishery, it was seen that there is a negative relationship between the great quantities of the two-year fish with the strength of the Leeuwin Current, measured two years before the fishes’ spawning period. Another was also the whitebait. According to studies, it was concluded that the stronger the Leeuwin Current was, the greater the relative catch of whitebait will be in the next year. The presence of Australian salmon in South Australia was also related to the Leeuwin Current.It was expected that when the Leeuwin Current was flowing strongly and that warmer waters penetrate onto the continental shelf, it was also expected that the fish may simply migrate offshore into deeper cooler waters.

Definition of X- Internet Essay

Many people think the Internet and the Web are the same thing. They’re not. The Internet is a piece of wire that goes from me to you and from me to 300 million other people in the world. The Web is software that I put on my end of the wire, and you put on your end — allowing us to exchange information. While the Internet (the wire) evolves gradually, the software on the wire can change quickly. Before the Web, other software was clamped onto the Internet. WAIS, Gopher, and Usenet were the dominant systems, and there were companies that were doing commerce using those software models. I call this the â€Å"executable Internet,† or X Internet, for short. X Internet offers several important advantages over the Web: 1) It rides Moore’s Law — the wide availability of cheap, powerful, low real-estate processing; 2) it leverages ever dear bandwidth — once the connection is made, a small number of bits will be exchanged, unlike the Web where lots of pages are shuttled out to the client; and 3) X Internet will be far more peer-to-peer — unlike the server-centric Web. This scenario could be marred by two threats: viruses and lack of standards. Once executables start to move fluidly through the Net, viruses will have perfect conditions to propagate. Standards, or rather the lack thereof, will block the quick arrival of X Internet. I can’t see Microsoft, Sun, IBM, or other traditionalists setting the standards. The Web-killer’s design will emerge from pure research, academe, or open source — as did the Web. What It Means — No. 1: Web-centric companies get stuck holding the bag. They will wake up one day with hundreds of millions of dollars of legacy code on their hands. Yes, their brands will remain intact, but their technology will suddenly be very outmoded. Yahoo!, eBay, and AOL will find themselves competing with a new wave of commerce players that market, deliver, and service using the superior technology of X Internet. One of the upstarts will Amazon Amazon. What It Means — No. 2: Investors get happy. The new wave of startups will race to market with X Internet, blasting old Web infrastructure and commerce companies out of their path. Internet creative destruction, round two. What It Means — No. 3: Peer-to-peer (P2P) networking rockets. The X Internet’s â€Å"smarts everywhere† design will enable an epidemic of Napstering. Courts, legislators, governments, companies, and other rule makers will have to contend with an empowered and ever more  liberated, unruly populace — armed with technology that allows them to bypass economic toll roads and bridges. What It Means — No. 4: If you are a Global 2,500 company, get ready for another round of change. This means: 1) overhauling the skills of your technologists; 2) destroying perfectly good Web sites in favor of the X Internet; 3) dumping Web-centric suppliers; and 4) retooling organizations. Change management will get a new test. As the Internet expands, two new waves of innovation — comprising what Forrester calls the X Internet — are already eclipsing the Web: an executable Net that greatly improves the online experience and an extended Net that connects the real world. An executable Net that supplants today’s Web will move code to user PCs and cause devices to captivate consumers in ways static pages never could. Today’s news, sports, and weather offered on static Web pages is essentially the same content presented on paper, making the online experience more like reading in a dusty library than participating in a new medium. The extended Internet is reshaping technology’s role in business through Internet devices and applications which sense, analyze, and control data, therefore providing more real-time information than ever before about what is going on in the real world. The X Internet will not be a new invention, but rather the evolution of today’s Internet of static Web pages and cumbersome e-commerce mechanisms into a Net that relies on executable software code to deliver more interactive experiences. Executable Internet applications use downloaded code like Java and XML to enhance the user experience with pop-up menus, pick lists, graphics and simple calculations, according to a recent Forrester report entitled â€Å"The X Internet.† An easy way to understand how the X Internet will work is to imagine that a band wants to distribute asong over the Net. Rather than worrying about which audio player people want to use, an executable file will deliver the song and the audio player at the same time. â€Å"With an executable, you can distribute movies the same way you distribute songs,† Forrester research director and report author Carl Howe told NewsFactor Network. â€Å"It just makes the models work better.† Building the X-Net The report also employs an example of a person building a house. With today’s  Internet, a builder would have to find, then try to follow, an article detailing how to frame a window. When it was time to installthe bathroom, the would-be plumber would then have to find an article dealing with that topic. Executable Internet applications would demonstrate to a builder, step-by-step, how to frame a window. When it came time to install the bathroom, the carpenter would simply be replaced by a plumber. â€Å"Instead of reading a book, you have a conversation about the work you’re trying to do,† Howe wrote. Forrester is also predicting the widespread adoption of another X Internet — but this X stands for â€Å"extended.† The extended Internet will include the widespread adoption of real-world appliances, like air conditioners or car tires, that communicate with owners or manufacturers via the Internet. The extended Internet will come with the inclusion of cheap sensors in thousands of everyday products, an era that will begin around 2005, Forrester predicts.

Wireless Networked Digital Devices The proliferation of mobile computing devices including laptops, personal digital assistants (PDAs),and wearable computers has created a demand for wireless personal area networks (PANs).PANs allow proximal devices to share information and resources.The mobile nature of these devices places unique requirements on PANs,such as low power consumption, frequent make-and-break connections, resource discovery and utilization, and international regulations. This paper examines wireless technologies appropriate for PANs and reviews promising research in resource discovery and service utilization. We recognize the need for PDAs to be as manageable as mobile phones and also the restrictive screen area and input area in mobile phone. Thus the need for a new breed of computing devices to fit the bill for a PAN. The above devices become especially relevant for mobile users such as surgeons and jet plane mechanics who need both hands free and thus would need to have â€Å"wearable† computers.This paper first examines the technology used for wireless communication. Putting a radio in a digital device provides physical connectivity;however,to make the device useful in a larger context a networking infrastructure is required. The infrastructure allows devices o share data,applications,and resources such as printers, mass storage, and computation power. Defining a radio standard is a tractable problem as demonstrated by the solutions presented in this paper. Designing a network infrastructure is much more complex. The second half of the paper describes several research projects that try to address components of the networking infrastructure. Finally there are the questions that go beyond the scope of this paper, yet will have he greatest effect on the direction,capabilities,and future of this paradigm. Will these networking strategies be incompatible, like he various cellular phone systems in the United States, or will there be a standard upon which manufacturers and developers agree, like the GSM (global system for mobile  communication)cellular phones in Europe? Communication demands compatibility, which is challenging in a heterogeneous marketplace. Yet by establishing and implementing compatible systems, manufacturers can offer more powerful and useful devices to their customers. Since these are, after all, digital devices living in a programmed digital world, compatibility and interoperation are possible. Introduction to X internet : X internet seminar topic explains about concept of new generation internet applications and its updations in software and hardware technologies. Concept of x internet will help in different aspects of businesses, education and power full ways then present standards that we see in internet. Using this technology users can connect to physical objects by adding intelligent technologies which will increase connectivity between humans and physical objects. In this paper we provide detailed explanation on the extended internet, advanced cooperative wireless technology, context awareness, built in intelligence and more.

What Do Artists Do Essay Example | Topics and Well Written Essays - 250 words

What Do Artists Do - Essay Example This essay discusses that the nation was bitterly divided that the returning veterans got almost no recognition for their efforts. In this environment of an ongoing debate, the role of Lin was to build a memorial, honoring the human sacrifice of the war while at the same time neither praising nor criticizing the war itself.Ass the report stresses at the center of the memorial is a long, tightening, V-shaped wall of black granite, engraved with the names of the missing, the captured as well as the dead-totaling to 58,000 names. This memorial suggests a modern entrance to an old burial mound even though it lacks entrance. Thus, the extremely polished surface serves as a mirror providing a reflection of the nearby trees, Washington Memorial as well as the visitors passing by.  As they enter along the walkway from either side, visitors are not aware at first of the low wall at their feet. The monument starts, unnoticed just as the war itself did; a few support troops sent to a distant and small country, a few deaths in the nightly news. As visitors descend along the downward-sloping path, the wall becomes taller and taller, towering overhead, and so do the names increase. People oftenly reach out and touch the letters, touching their own reflections. A corner turns at the lowest point of the walkway, with the wall at its highest. The path climbs upwards, and the wall falls away. Drawn from both the Washington Memorial and Lincoln Memorial, visitors leave the war behind.

Confrontation Essay Example | Topics and Well Written Essays - 1000 words

Confrontation - Essay Example Be it the pure arts or humanities, criticism has always been there to point put any deviations from and contradictions to the ideologies and moralities, and the sets of rules, established by the actions of the people. This effort can be traced back to Aristotle, when he, in his Poetics, put forward the theory of literature that offered positive criticism to the literary works. Or the ideology of Karl Marx, called Marxism, for instance, objected to the sociopolitical conditions and offered an alternative method of approach that not only affected the social sciences, but even artists and literates grabbed on to the philosophies proposed by him. Flash forward to the recent exhibition, Art of Confrontation, and it is apparent that the struggle is far from over. In the humanities, the critical social theory, or the critical theory for short, has had an evolution, from two distinct origins and fields_ namely the literary theory, that proposes criticism purely in the arts and literature, and the social theory of criticism, that examines and analyses sociopolitical practices_ to the recent more overlapping critical social theory that combines the two fields and tries to provide a better and deeper understanding of society by incorporating all branches of humanities. Ultimately, the goal is to mold society according to the principles of Enlightenment, and to pursue it. Similarly, artists have for long seen it as their role as social scientists, and have produced work that has criticism and progression as its basis. Culture is by the people, for the people, and this medium, when tapped, can have amazing affects on the lives of the people. Sculptures, paintings and other form of art, even literature, can forever capture the thinking, feelings, and issues of the people of their time for future generations to study and learn from. As is said, it bears testimony. It stands as a reminder of the struggles of the people and their aspirations, and can send strong waves of renaissance and reform. Sometimes it has political shades to it and sometimes it provides a parallel medium to view issues, with a new light, leading, however, to the same goal_ Enlightenment. This form of art has come about to be known as critical art, and together, critical social theory and critical art, both high culture and mass culture, aim to propagate the acquisition of critical k nowledge to instill in individuals a sense of psychoanalysis and self-reflection so that society as a whole can emancipate itself from all forms of oppression, vice and domination. The underlying agenda of all activist movement has always been human rights, and the dignity and freedom that is associated with every individual. War,

A Reaction and Opinion on the TIVO Service Essay

A Reaction and Opinion on the TIVO Service - Essay Example This has happened in films for several decades: for example, the Aston-Martin cars that James Bond always drives or the prominently placed soft drinks such as Coke in many teenage films. This is starting to occur in TV programs as well. TIVO has an edge over other companies because it was the first one to offer such service, but many cable companies are now competing with them. For example, most cable companies, such as Comcast, now offer Digital Video Recorders that can be rented on a monthly basis and perform the same function as TIVO. These services are also cheaper than TIVO. Professional athletes are in the public spotlight for one simple reason. They are incredibly good at playing certain sports that many people want to watch and so they are paid a lot of money. These athletes are paid huge sums of money because of the amount advertisers will pay TV stations for the sports and the amount that fans will pay to attend the events. But unfortunately, professional athletes are also expected, for reasons that are not entirely clear, to be "role-models" for fans in general and the young in particular. For better or worse, people look up to athletes, and so parents/society expect them to act in a certain way.

ICT AND LITERACY - Essay Example rofound impact on our education, society and economy .But, teachers are not being well informed on ICT field as in contrast happens with the young pupils, considered as â€Å"digital natives†. Both teachers and pupils have to be taught to use the above devices and retrieve the appropriate information from the suitable web sites. The impact of technology on human lives will surely increase in times to come. The dependence of human race on technology is increasing at a terrific pace. Technology is no more meant for the ones who hold a degree of it like the software engineers and technicians, etc. The arena of technology use has penetrated to the common people segment also. Whether it is about withdrawal of money from an ATM, net banking, or reading voice messages on the telephone, technology has its presence everywhere. Thus, it becomes rather necessary to make the world population technologically literate. This will provide ease to the people to work and understanding the working in this rather technological world of today. Thus, the importance of ICT in literacy not is denied (Alan Rodgers, 2002). ICT has proved to be a huge success in value addition to students in every phase of learning and for every age group, be it children or adults, ICT offers learning advantages to all of them and can be used to provide learning in any discipline. Though, it is important to note that the ICT technologies have to be customized in order to suit the requirements of learners. Accepting the fact that being educated and adapting to today’s school and social needs, in my perspective, constitutes the major challenge of any time and the characteristic feature of the literate citizen in order to be considered productive and useful and not marginalized. And the current challenge regards information and communication technologies (ICT) that play an essential role in supporting daily life in todays digital society. They are used at school, at work, in day-to-day relationships, in

GRENDEL BY JOHN GARDNER Essay Example | Topics and Well Written Essays - 750 words

GRENDEL BY JOHN GARDNER - Essay Example In  Grendel,  however, he is an intelligent and temperamental monster, capable of rational thought as well as irrational outbursts of emotion. The novel follows Grendel through three stages of his life. The first stage is his childhood, which he spends innocently exploring his confined world, untroubled by the outside universe or philosophical questions.  The second step, which decisively makes Grendel an adult, occurs when the bull attacks him, prompting him to realize that the world is essentially chaotic, following no pattern and governed by no discernible reason. The third and final stage of Grendel’s life encompasses his fatal battle with Beowulf and the weeks leading up to that battle. In this reading, Gardner establishes Grendel as a dark, but poetic spectator to man’s pretensions to civilization (Merrill 164). For instance, Grendel has observed Hrothgar’s rise to power, so he offers a sardonic account of how roving bands evolved into savage tribes. Grendel is also contemptuous of the Shaper’s influence on Hrothgar’s men, and he asks â€Å"Did they murder each other more gently because in the woods sweet songbirds sang?† (Gardner 62). This is where he emphasizes the dangerous allure of art, that is, he exposes the irrepressible human tendency to substitute unpleasant realities with consolatory myths (Merrill 165). The Shaper, for example, tells the Danes stories of their heritage so that the Danes learn to see themselves within a certain moral context, as inheritors of a proud tradition and consequently feel a need to adhere to the strict moral and ethical code that the Shaper has established.  This crystal clear vision of wha t they need to believe in to make their world a meaningful one comforts them. They feel safe in a world which offers a clear distinction and role assignment: kings are kings, warriors are warriors and monsters are monsters. Unlike them, Grendel is not oblivious to the fact that what they

Avon Products Case Study Example | Topics and Well Written Essays - 1250 words

Avon Products - Case Study Example The company faced a challenge of flattening revenues and even declining operating income. There were many factors that led to this decline, one of the issues was that the company had grown at a faster proportion than the infrastructure and talent could hold. This called for an immediate intervention to save the company from collapsing. The current CEO who was known as Jung and the executive team launched a basic restructuring of the organization in starting of 2006 (Effron, 2009). Question two Leaning and transparency model was one that was targeted to bring change in the organization. For an organization to bring in change, one of the ways to ensure that change does not impact negatively to the organization is through training of employees. By doing so, employees are able to learn new tactics to use in order to integrate with the new change. In addition, employees are able to acquire skills to enable them to cope with the new requirements of the change. The company investment in exe cutive talent is one way of implementing learning model. The company planned to refurnish new talents as a way of ensuring that the company keeps up with the latest growth of the company. The employee’s new knowledge was also to be used as a model of ensuring that they are able to sustain the current growth of the company. ... The company aim to transform the organization through establishing bodies that would oversee transparency process is another example that assisted me to identify the model. The company aim of changing the top management behavior through teaching them on how to maintain a good image of the company is an aspect that is in learning and transformation model. The company also went ahead to recognize every personnel behavior as critical to the overall success of the business. These transformations were supported by performance reviews that were aimed at keeping an eye on the individual performance (Harris, & Hartman 2001). Question three One of the evaluation information that was obtained is that there is a need to create an efficient communication channel which will ensure that organizations processes are carried out in an efficient manner (Zofi, (2011). Communication plays a great role in tackling problems that might affect the organization. Efficient communication also ensures that ther e is a good relationship between leaders and their subordinates. In addition, communication plays a great role in enabling the organization to solve any issue that might affect the organization performance. This evaluation problem was to ensure that poor communication was eradicated and leaders implement policies that would enable the top management and low ranked employees to communicate frequently an aspect that would positively impact on the performance of the employees. Lastly communication would enable leaders to assess the talent of their employees. This is an important move in ensuring that categorization of talents in the organization is done appropriately (Harris, & Hartman 2001).
