Dinosaurs have fascinated and baffled paleontologists and evolutionary biologists for decades. How such gigantic animals, some of which weighed over ten tons and stood over 50 feet tall, could be so agile and energetic and how exactly did these creatures regulate their body temperature are some of the questions that remain under debate to this day.

Current studies of dinosaur fossils suggest that they were warm-blooded. While their leathery skin, skull shape, and counter-balancing tails are reptilian, their overall anatomy, suggests that they evolved from cold-blooded ancestors into a warm-blooded species. Unlike cold-blooded reptiles, whose legs are generally sprawled outwards, dinosaurs had legs that extended straight below the pelvis. They also had four-chambered hearts, a characteristic feature of warm-blooded animals that is almost never seen in modern reptilians.

The dinosaurs resembled both reptiles and mammals in their physiology. In fact, dinosaurs are often seen as the link between reptilian and mammalian species. Both mammals and dinosaurs have numerous tiny holes called “nutrient foramina” in their femoral bones. These foramina supply blood and nutrients to the living bone cells within. This is a feature of warm-blooded animals with a high metabolic rate and an active lifestyle. In dinosaurs, these foramina were found to be much larger and more numerous than those found in mammals, suggesting that dinosaurs were actually much more agile and active than mammals.

Several paleontologists also argue that dinosaurs must have been warm-blooded because standing erect requires the body to generate enough of its own heat and not rely on the ground for warmth (as lizards, snakes and alligators do). Moreover, a predator as large as some dinosaurs would have to be unusually nimble and quick in its movements. Such activity would require a high metabolic rate, which in turn suggests that dinosaurs were, indeed, warm-blooded.

Many have attempted to explain how dinosaurs became extinct. Some speculate that they were unable to adapt to the withdrawal of the second ice-age, some say they were wiped out by a meteorite, a few even argue that the extremely steep growth curve of dinosaurs might somehow have contributed to the end of this magnificent species. Each theory has its own shortcomings. The first one does not take into account the fact that dinosaurs had withstood the climatic changes brought about by the first ice age. The second theory seems unlikely because several contemporary species survived while the dinosaurs became extinct. The third one assumes that all types of dinosaurs grew at the same rate. Smaller dinosaurs, some of which grew only to a height of six inches, would have had a much slower rate of growth. Their extinction cannot be explained by this theory alone.

While the wait continues for a decision in the long-running Google Book Search (GBS) lawsuit and settlement proposal, a new study throws cold water on the idea that Google Book Search is bad for the publishing industry. The study suggests that Google's scanning and digital previews of books may be helping publishers sell more books. The study, published last month by Hannibal Travis, an Associate Law Professor at the Florida International University College of Law, examines the revenues and operating incomes of U.S. publishers that claim they will be most affected by the settlement and “finds no evidence of a negative impact upon them." The study has found no support for an imminent monopoly by Google over books. Publishers of printed books continue to increase their sales and profits. Their rate of sales growth has increased since the scanning of books into GBS by Google. Book sales are growing faster than retail sales or the economy as a whole. These findings suggest that the benefits of digital libraries to American students and persons of limited disposable income, in terms of accessibility of information about and inside books, need not be sacrificed to save publishers from “Napsterization” and the loss of their customers. Moreover, the potential gains in economic efficiency, freedom of expression, and global democratization represented by digital libraries like GBS are more likely to outweigh any damage done by GBS to publishers.

Yet there are also many ways these studies underestimate the magnitude of the publishing industry`s hardship. Even assuming that digitization inherently is not bad for the industry, reliance on technology can cause several immediate and future complications. Though there are no immediate technical problems, forms of media and file types change frequently. One would be hard-pressed to find a way to play an 8-track cassette or Betamax videotape today, and likewise digitization software designed for earlier operating systems is often rendered inoperable in just a few years. Differences in display hardware will also contribute to altered perceptions of the reader. Digital copying also creates a host of legal implications under the U.S. Copyright Act.

As a result of such contradictory evidence, it is uncertain whether the publishing industry will suffer seriously as a result of mass digitization of books and, hence, whether the GBS should be supported or stemmed. There is only one area of agreement in this debate — that the existing research and studies are inadequate for measuring the impact of digitization on the publishing industry.

Over the past few years there has been a lot of discussion about the animation bubble in Canada, and the booms and busts the industry seems to go through every 7 years or so. This last boom, it could be argued, lasted well over a decade. However , such growth is not without substantial risks. The industry has long argued that one reason why the local animation industry has lagged behind its counterparts across the globe is its inability to compete against low cost animation from Asia. The government, in a bid to address this disparity, has enacted a law requiring broadcasters in Canada to acquire 50 percent of their animation content from local animation studios.

The response appears to have been substantial. According to figures, the total animation content procured from local studios rose from $10 million in 2001 to $180 million in 2011, with no letup anticipated in the next decade. The software tools available today, mostly Flash, allow smaller companies to produce animation at a rate that was not conceivable even 15 years ago. Because of this major shift, entire productions, TV series, and features are being produced almost entirely in house using a crew that is almost entirely Canadian — a smart thing to do because it allows the broadcasters to take advantage of the lucrative Canadian and provincial tax credits available for just this kind of production. As promising as this is for local studios, this increased patronage poses dangers for them, too.

First, local studios risk expanding too fast and overextending themselves financially, since most are small concerns unlike their Asian counterparts. They often need to make substantial capital investment in building technology capability in order to handle the larger volume of work. If, thereafter, the content fails to work with the audience and further episodes get cancelled, such firms can face potentially crippling losses.

A second risk is that these studios will end up creating work that is too specific to local audiences. Given the increased dependency on local broadcasters, the studios run the risk of creating content tailor made for local audiences rather than remaining culture neutral. This substantially reduces the ability of their products to sell beyond local boundaries.

Third, a local studio that secures the contract from one large broadcaster often runs the danger of becoming — and remaining — dependent on that single broadcaster. Even in the best of circumstances, fierce competition from Asian studios makes it difficult for small studios to broaden their customer base internationally: When such firms have nearly guaranteed orders from a single local benefactor, complacency from their current success may arise.

In 1848, Marx, supported by Engels, completed the “Communist Manifesto.” The "Communist Manifesto" attempts to explain the goals of Communism as well as the theory underlying the movement. It argues that class struggles, or the exploitation of one class by another, are the motivating force behind all historical developments. Class relationships are defined by an era`s means of production. However, these relationships eventually cease to be compatible with the developing forces of production. At this point, a revolution occurs and a new class emerges as the ruling one. This process represents the "march of history" as driven by larger economic forces. The “Communist Manifesto” stated that all men were born free but that society put the majority of men in chains. Engels referred to the book as being the “very way of life.” In a higher phase of ideal communist society, the enslaving subordination of the individual to the division of labor and also the antithesis between mental and physical labor vanish. Labor becomes not only a means of life but life`s prime want and the productive forces increase with the all round development of the individual. All the springs of the cooperative wealth flow more abundantly."From each according to his ability, to each according to his needs!" echoes Marxism. The nonstarters were considered the ones who wanted a free enterprise system advocating maximum productivity. Economic progress in Marxist regions has been sterile because it can imagine no change except through the extension of Marx`s ideology — the argument that the elimination of social classes cannot come about through reforms or changes in government, but rather, a revolution is required. Indeed, some forms of neo-Marxism resemble little more than a giant "conspiracy theory," whereby a capitalist ruling class is able to manipulate other classes in society for their own ends and benefits.

Marxist society greatly undervalues non-economic forces and wraps a great deal of belief in an economic shell at the expense of non-economic issues. In fact, modern industrial society in specific is characterized by class conflict between the bourgeoisie and proletariat. However, the theory that productive forces of capitalism are quickly ceasing to be compatible with this exploitative relationship is greatly over emphasized. More importantly, much Marxism — both old and modern — has tended to ignore the role and position of women in society. Women tend to be marginalized in much Marxist theorizing, possibly because of the focus upon work relationships. This criticism is irrelevant and obsolete in current context. In comparison, capitalism, however, as an economic and political system, has proven to be more durable and flexible than Marx imagined.
