Charles Darwin’s publication of the theory of evolution through natural selection is one of the pivotal moments in the history of science. But the theory was unveiled only in the middle of 19th century, by when great strides have already been made in other fields of science. Yet, when compared to the complexity and cumbersomeness of theories in the fields of astronomy, quantum physics or discrete mathematics, Darwin’s theory is remarkable for its simplicity. Despite this fact the theory has generated a lot of controversy – both among the general public and among intellectuals. Leading the aggression are the religiously orthodox, who see a threat to the tenets of their faith. To overcome their insecurities they adopt one of two approaches. First, they try to reject evolution as valid scientific theory for want of adequate evidence supporting it. When this fails, they co-opt the theory into a religious understanding and project the process of evolution as God’s . . . Read MoreContinue Reading
Steve Jobs is one of the prominent inventors and pioneers in the field of information technology. Some of his creations such as the iPhone speak highly of his vision in recognizing technologies of the future. By introducing products such as the iPhone, he took Apple Computers to new heights through its exceptional performance and features.
In order to grow any business innovation is a key element. Without innovation the business would stagnate and will soon be consumed by more competitive firms. At the beginning of Apple Computers’ corporate life, the Mac computers were a great product innovation. In more recent years, it is the iPhone. The quality and popularity of iPhone is such that it has even overtaken companies like Blackberry. At the beginning of the IT revolution in the 1990s companies like Microsoft were taking huge strides in Graphic User Interface . . . Read MoreContinue Reading
Prior to September 11, 2001 many police agencies nationwide practiced Community Oriented Policing. The aftermath of 9/11 saw many police agencies revert back to traditional policing. Describe why you believe this is or is not beneficial for a police organization.
The September 11, 2001 terror attack on American soil, carried out by Al-Qaeda, is a significant politico-historical event in many respects. In its aftermath the nation saw a slew of counter-terrorism measures, some of which (like the PATRIOT Act) have been very controversial. The effects of stringent security measures that were taken in the wake of 911 have percolated even to the police department. Since 911 there have been structural and functional changes witnessed in police departments across the country. A major change is with respect to Community Oriented Policing, which has been nearly done away with. Although efficiency and rapid co-ordination to act upon intelligence has been . . .

Memory is an important component of any computer. A part of the Central Processing Unit (CPU) of a computer, memory performs either of short-term or long-term storage functions. At a conceptual level, memory can either refer to the storage devices themselves (hard-drives, DVDs, etc) or to the data/information stored therein. The Random Access Memory (RAM) is the most important for the functioning of a computer, for it is essential for immediate and high-speed computing operations. But RAM has a limitation in terms of its capacity but the access time is very impressive. In contrast, secondary memory devices offer vast storage capacities for information with the trade-off being slow access time.
Computer memory devices are mostly made of semiconductor circuits such as Integrated Circuits (ICs). The basic storage unit for semiconductor memory is called a cell which can store a unit of binary information (0 or 1). Cells are in turn part of memory words of lengths such as . . .

The media item chosen for this essay is Just a Minute – a flagship radio comedy show broadcast on BBC Radio 4. It is based on a 4-member panel format, where contestants have to speak on any given topic for a full minute without ‘hesitation’, ‘repetition’ or ‘deviation’. Having premiered at 1967 as a weekly show the program is still running today. It is one of the longest running in the history of radio and comedy. (Crisell, 2002, p.26) The main reason for its success is due to how it allows endless creativity and humour within a simple framework of rules. Though the three-point rules are simple to understand, the panellists seldom find them easy to follow during the impromptu situations they find themselves in. Though it is a competitive game-show format, winning is less important than amusing and entertaining the audience. The audience for the show falls into two categories: radio listeners and in-studio attendance. . . . Read MoreContinue Reading
This article takes a critical look at one of the most recognizable cultural icons in American history – the Barbie doll. While admitting to the popularity and appeal of the Barbie doll across generations, Emily Prager finds certain faults with what it symbolizes. The fact that the doll was first conceived and designed by a man is the first of Prager’s objections. She contends that Barbie’s fulsome breasts and thin waistline accentuate her sex-appeal, thereby reducing femininity to the contours of body shape and skin color. Prager asserts that this physical perfection on part of the most popular doll undermines the feminist movement and other feminine ideals. Prager acknowledges that Barbie does serve as a role model in terms of her liberated sense of style and living. The showcasing of Barbie’s bohemian lifestyle, spanning condos, fashion plazas, swimming pools and beauty salons is appealing for young girls. Yet, her combination of verve and freedom does not . . .

By properly channelling scientific knowledge about oil-consuming bacteria, vast untapped sources of energy could be availed. Two main ideas for accomplishing this goal are being mooted. The first involves introducing bacteria that will attack antagonist bacteria, thereby reducing the emission of methane. The second method involves applying bacteria that will serve as a catalyst for the oil, thereby aiding transportation.
It is a little known fact that germs co-habit energy reserves underground and that the actively feed on select oil compounds and leave by-products. These tiny bacteria are called archaea. Scientists are now exploring ways of tapping into these natural processes toward efficient production and transportation of energy. The cherished goal at the moment is to make extraction possible from oil sands – a resource that is abundant in Canada.

Cell phones are ubiquitous symbols of the technological age. With a cell phone our aural and cognitive faculties are extended in an unprecedented manner, making our living experience very unique. For example, wherever we may be located geographically, we can get in touch with family members anywhere in the world and at any moment we choose. There are practical utilities such as parents checking on their children, making emergency calls when the elevator or the car breaks down, etc. Such are the range of benefits of cell phones that presently, across the globe, there are more than 3 billion units in use. That is nearly one in two people in the globe have a cell phone attached to their identity. This statistic makes it clear that cell phones have become inevitable to our lives. A link has been identified between some kinds of electromagnetic radiation and some cancers. These forms of electromagnetic radiation include “ultraviolet radiation, X-rays, and gamma rays.

Pablo Picasso is one of the greatest visual artists of the twentieth century. Born in Spain in 1881, he later moved to France where he spent most of his productive years. Though the public remember him as a painter, he also excelled as a sculptor, graphic artist and ceramist. He gained reputation on the basis of his “technical virtuosity, enormous versatility, incredible originality and prolificity”. (The Columbia Encyclopedia)
Though a naturally gifted artist, Picasso honed his skills at the Royal Academy of Art in Barcelona at the turn of the twentieth century. He then moved to Paris as the city was famous for its art patronage. He lived here for the next four decades of his life which was also the most creative and productive phase in his artistry. He produced such works as The Old Guitarist (1903). This early phase is noted by biographers as Picasso’s ‘blue period’, typifying the liberal use of the color as well as the melancholy mood carried by the paintings. . . . Read MoreContinue Reading
Social media has been successfully adapted by a few MNC’s as channels for research and innovation. They have also shown their potential in promoting knowledge sharing and team building. The value of social media technology to improving overall organizational effectiveness is borne by statistical and empirical evidence. The use of Twitter for professional enhancement is well established now. The educational philosophy of constructivism offers a strong rationale for greater social media integration within the organization. These days, just as the sweep and reach of social media has increased, so have the niche media spaces that facilitate the interaction. Hence, beyond the prominent household names of Facebook, Twitter and LinkedIn, we now have other specialized avenues for interaction like wiki portals and Youtube repositories of learning videos. In today’s competitive business environment, it is imperative for mutli-national companies . . . Read MoreContinue Reading
