...Words cannot fully explain our experience of this world, yet we try to do this expressly or inadvertently in our private reverie or shared moments with others. When presented with a work dealing with text, we become in varying degrees aware of our cognitive faculties. A work which is presented to us in a direct form where its meaning and interpretation are intentionally straightforward and meant to be immediately grasped, perhaps demands less cognitive skills from us to experience a satisfactory closure. However, and because words are “free-floating signifiers” (Simon Morley, 2001, p.33), with meanings which are malleable, a piece of work dealing with text that considers this as a fundamental element, evokes a larger inventory of our cognitive powers. From here, we traverse and delve into our reservoir of fictive ingenuity when we try to make even greater sense of this work. Thus, rendering us susceptible to suggestion, and the infinite possibilities of imagining the world and ourselves in different time and space. This concept of “open work” (1980, p.45) as observed by Umberto Eco is central in my proposal of study and it aims to investigate the state of immersion in fictive discourse with others, the world and ourselves. The proposal examines how an installation piece dealing with text, time and space when presented as an “open work”, is able to engage the audience’s fictive discourse, and intensify, in particularly this notion of immersion and presence. One of the key...

...Cockfighting Observable behavior is the pivot upon which symbolic interactionism revolves around. However, it is not the behavior per se but the covert and overt aspects and the interactions that utilize these behaviors that carry the symbolisms and meanings. In the article, cockfighting is the observed behavior and through it, a whole cultural identity is revealed. Cockfighting could very much be the physical manifestation of an otherwise subdued strain of culture which glorifies men and their masculinity in the Balinese society. The interaction of the men with their cocks highlights the cock as the physical object as the center of a dynamic display of symbolic interactionism. For example, as foreshadowed by the obvious double entendre, the cocks in Bali villages are masculine symbols. Moreover, its metaphorical uses run in the lines of “hero” and “tough guy”. The big event that is cockfighting shows the importance that the society places upon these masculine concepts. Therefore, the Balinese men show utmost reverence for their cocks not only because they are pried fighters, but also because of the symbolism it carries for them. This, in turn, reflects a core principle of the theory wherein behavior is based on the meaning given to the object receiving the behavior and action. With the object being the cocks and the symbolism being their masculinity and ego, there have been practices as frequent grooming, bathing and even hand-feeding of the animals that show a reflexivity...

...The impact of today’s technology on family and work life The world has witnessed a whirlwind of change since after the industrial revolution and no sector is it more prevalent than in Technology. Prior to the twenty first century, majority of the convenience we are accustomed to today were non- existent, and where they do people were engaged in providing them; be it banking automatic teller machine, lift operating, telephony, etc. Personal development has taken on a whole new meaning due to advancement in technology and today’s employees are in jobs created mostly due to technology. No one would have visualised decades ago that there would be applications to do everything we need to and communicate and we can have most of them on our cell phones and or accessed them at a single click from our laptops and desktops. The impact is humongous. In sales and marketing for example, the customer has access to information like never before and in most cases would have made initial buying decisions based on that information and before being approached by a salesman. Technological advancement is visible in our classrooms too. Before, lectures were delivered using chalks and blackboards. Today, lectures are delivered via projectors. There is a college in the state of Philadelphia where all students use laptops. In other words, education has become paperless, and it is so in many parts of the world now. A nation and people that has contributed significantly into making technology accessible...

...I want to conduct a little experiment. I'm going to make a true statement and then you're going to analyze your reaction to it. Ready? Here we go... I, J.T. O'Donnell, work much harder than you do - and so do a lot of other people. There. I said it. How are you feeling? What was your initial thought? Did you agree? Did you feel offended? Angered? Sorry for me? Did statements start running through you head, such as: * That's not true. * It's not fair. * I bust my !@#$ more than anyone. And, I bet you eventually concluded with: You have no idea how hard I work. Am I right? I hope so. Here's why... The Truth Is Subjective When It Comes To Hard Work If you go back to the beginning of this post, you'll see what really intensified your reaction was me prefacing it by saying it was "true." I made it clear I believed it 100%. Which means, when I said it, I was implying I'm better than you and deserve more than you. Now, I don't think for a second that I work harder than you. Yet, the above demonstrates how one person's truth may not be yours. Especially, when it comes to how hard you both work. (For example, here's an article that shows how working hard doesn't matter when you are competing against hundreds of other candidates.) The Problem With "Hard Working Americans"... I wrote this post to make a point: many people today are "working hard" and feeling like they're getting shafted. Granted, times are tough and the working class is struggling. Every news...

...1. Record. During the lecture, record in the main column as many meaningful facts and ideas as you can. Write legibly. 2. Reduce. As soon after as possible, summarize these ideas and facts concisely in the Recall Column. Summarizing clarifies meanings and relationships, reinforces continuity, and strengthens memory. Also, it is a way of preparing for examinations gradually and well ahead of time. 3. Recite. Now cover the column, using only your jottings in the Recall Column as cues or "flags" to help you recall, say over facts and ideas of the lecture as fully as you can, not mechanically, but in your own words and with as much appreciation of the meaning as you can. Then, uncovering your notes, verify what you have said. This procedure helps to transfer the facts and ideas of your long term memory. 4. Reflect. Reflective students distill their opinions from their notes. They make such opinions the starting point for their own musings upon the subjects they are studying. Such musings aid them in making sense out of their courses and academic experiences by finding relationships among them. Reflective students continually label and index their experiences and ideas, put them into structures, outlines, summaries, and frames of reference. They rearrange and file them. Best of all, they have an eye for the vital-for the essential. Unless ideas are placed in categories, unless they are taken up from time to time for re-examination, they will become inert and soon forgotten...

...Songs in our generation convey a large variety of meanings, this particular song, “House that Build Me” effectively conveys its theme and tone through a series of literary techniques. This song shares the story of a young girl who ventures out into the real world only to realize that she has lost her way. She feels distant and broken inside and realizes that there is only one way to fix this emptiness. She then goes to visit her very first home where all her fondest memories were made only to find that it is now someone else’s home. She implores the current resident of the home to let her in and assure her that she comes with the purest of intentions. As she walks around the house she realizes where she came from, as well as the values and dreams she was raised with. The very first literary device used is one of personification, used in the verse “From the house that built me.” This line, if interpreted literally, states that the house physically built the speaker. However, if this same line is interpreted figuratively, is reads that the house is such a big part of her memory and childhood that it is the foundation of who she is today. Throughout the song, the artist speaks of a house that she is visiting. This house is a symbol used to represent her roots and all the thing life used to consist of that are now gone. This could be representative of family that passed, morals that were compromised, or perhaps a negative change in one’s own personality. There are very few rhymes...

...A systematic way for designing breakthrough products or services includes two main steps. These two lead to considering of meaning first and technology second. This innovative method of creating a step forward product is clearly different from the common ones. It is so because such companies look for the original approaches not by analyzing the habits of consumers but by interpreting other very meaningful sources. They are called the interpreters. This concept includes people who can help for the companies to perceive the situation from the different perspectives. For example, the interpreters could be designers, psychologists, architects and many other experts who have explored the field. These people are very valuable for the company in order to create the new meaning of the product which attracts the customers more than the old one. In that way, consumers get a product which is above their expectations. Especially this ability to astonish the customers ensures the success for the company in the huge rivalry. However, often it is a complicated task to find the right interpreters. It is so because the companies need to look at the problem from the different angles and perceive it unusually. So it is essential to analyze the whole user’s experience. It means that not only the product is important but also its presentation or environment around it. The companies have to understand that there are a lot of factors which impact the customers’ decision. After this analysis the companies...

...Nichols v. Coolidge Mrs. Julia Coolidge, of Massachusetts, died January 6, 1921. As required by the Revenue Act approved February 24, 1919, c. 18, 40 Stat. 1057, 1096, the executors returned a schedule to the collector. He estimate the gross estate at $180,184.73 and allowed $77,747.74 deductions. They paid the amount assessed upon the balance. Their return did not include certain property transferred by the decedent through duly executed deeds and without valuable consideration, some to trustees and some directly to her children. The Commissioner of Internal Revenue held that, under § 402(c), the value of all this property at her death must be included in the gross state. He raised the assessment accordingly, and demanded the additional tax $34,662.65 -- here challenged. Section 402 directs that the gross estate shall be ascertained by including (among other things) the value at his death of all property "to the extent of any interest therein of which the decedent has at any time made a transfer, or with respect to which he has at any time created a trust, in contemplation of or intended to take effect in possession or enjoyment at or after his death (whether such transfer or trust is made or created before or after the passage of this act), except in case of a bona fide sale for a fair consideration in money or money's worth." Concerning transfer of the residences in 1917, the trial court charged “The effect of this transaction was to vest in the five sons named in the...

...Part 1 The idealized body can be different things depending on whom you ask this question too. For example in the picture Leigh under the Skylight the person is very overweight, bald, and even naked, but this is a full body portrait that the artist says talks about their personality. This meaning that the artist must of that it was the idealized body during that time in society. Now in the Male Torso in the African shows details of the torso area. This must have been showing contrast to the torso to define the way they look to the outside world and how they thought the torso should look. Although I don’t think that there will ever be a perfect body due to the fact that everyone will have their own opinion and the world will always be changing so different figures will look better in different periods of time. Another example of this would be how in midevil times that if you was fat it was good it meant royalty and wealth, but now days if you are fat it is considered bad because of what is shown to the world. They find skinny people more attractive with the “idealized” body. There are many different cultures that have different meanings for their body parts such as Africans found that neck and the head was the most important body parts to them. Then with Leigh under the Skylight show full body pictures so this takes part of their character and the way they act for what is important to them. Then in other cultures in the South Pacific they had tattoos on their body to show...

...Current Practice: Companies Ordinance (Cap.622) Section 122 This section deals with disputes arising from pre-incorporation contract. (1)Secction 122 of Companies Ordinance applies if a contract purports to have been made in the name or on behalf of a company before the company was incorporated; (2) Section 122 is subject to any express agreement to the contrary: (a) The contract has effect as a contract entered into by the person purporting to act for the company or as an agent for the company; and (b) the person is personally liable on the contract and is entitled to enforce the contract. (3) After incorporation, the company may ratify the contract to the same extent as if (a) the company had already been incorporated when the contract was entered into; and (b) the contract had been entered into on the company’s behalf by an agent acting without the company’s authority. (4) Despite subsection (2)(b), if the contract is ratified by the company, then on and after the ratification, the liability of the person mentioned in that subsection is not greater than the liability that the person would have incurred if the person had entered into the contract after the company’s incorporation as an agent acting without the company’s authority. Application of Companies Ordinance Section 122(2) rules out that the promoter is personal liable and can enforce the contract.

...What is politics and why is it important? “Politics” is a word that poses a multitude of meanings because of its international character. It originated from ancient Greece from the greek word for a city state which in terms originates from the word for community. It meant the “matters of the city”. Through the years and into the different languages its meaning drifted apart to some extent. In general this word is associated with the governing process. The way society is being ruled and the way people are being influenced and molded to believe in their representatives and their ideals and goals. This idea explains politics more as a tool for a one-way communication between the governor, whether he is the president of the republic or of the company or any other executive member that has power over a collective, and said collective. Being a one-way channel, this leads to the easy abuse of the method and the present day “bad ring” to the word. Even so this does not diminish the importance of “Politics”. Politicians and politics serve a vital role in society because, love them or hate them, in the current state of the international, or at least, local, community no other alternatives exist for the healthy life of a civilizations. Leaders and their one way communication will always exist at least for now. This is why politics is so important for us. The mentioned abuse of the system only occurs due to its reliance on trust. This explains why it so easily corruptible. It takes...

...AND INFORMATION. Data consist of raw facts, such as customer names and addresses. For data to be meaning full, it must be collected to constitute information. Information is a collection of data or facts organized in such a way that it has more value beyond the individual pieces of data themselves. For example, a set of data of customer names and purchases might provide information on a company's market demographics, sales trends, and customer loyalty or turnover. Every purpose data or collecting data is to transform them to information. Turning data into information is a process or a set of logically related tasks performed to achieve a defined outcome. This process of defining relationships between various data requires knowledge. Knowledge is the body or rules, guidelines, and procedures used to select, organize, and manipulate data to make it suitable for specific tasks for a specific period of time. Consequently, information can be considered data made more useful through the application of knowledge. The collection of data, rules, procedures, and relationships that must be followed are contained in the knowledge base. Companies face increased pressure to provide higher quality information faster and more efficiently. They want more transparent information in less time. There are demands that information must be faster with more transparency and come from every angle meaning they shouldnt be just providing information from one perspective . Many people require access to...
