Abstract
This paper explains that the concepts of heterochrony and Von Baer's law have provided compelling evidence as to the validity of evolution as a theory and even more importantly explains the mechanism by which evolution occurs. Next, the author relates that Von Baer's law is concerned with the morphological and therefore genetic similarities in certain species, especially in regards to embryonic development with the timing of the divergence in the developmental process amongst species; whereas, heterochrony is the differentiation of morphological aspects between two or more species based on different timing and rates for the same developmental process. The paper examines the hagfish, zebra fish, frog and pig to provide examples of various stages of embryonic development from the egg size and early cleavage, gastrulation and the development of the pharyngeal arches, urogenital systems, limb and the central and peripheral nervous systems.

From the Paper
"This statement reflects what is now typically known as Von Baer's law. It is important enough even on its surface--the fact the different embryos can be observed to develop similarly means that the observation of one species could lead to useful knowledge pertaining to a wider class of species. Furthermore, the mere existence of these morphological--and therefore genetic--commonalities in vertebrate species is easily observable evidence as to the interrelatedness of life, and more so of the closer relationships shared by more specific classes of animals (i.e vertebrates). But as exciting and compelling as these surface similarities may be, the deeper implications of Von Baer's law are far more essential.
"Von Baer did not stop with his observation that similar structures and even developmental patterns existed in all vertebrate species, but he also noted the timing of these developments and their digressions from each other. Charles Darwin, the father of evolutionary science, "recognized an evolutionary interpretation [of Von Baer's observations] of great potential...look for similarity in embryos since evidence of common ancestry is so often obscured by highly particular adult modifications.""

From the Paper
"Hans A. Baer and Merrill Singer, in African-American Religion in the Twentieth Century: Varieties of Protest and Accommodation, approach their subject employing a unique combination of conceptual and contextual elements. In addition, they seek to shed light on connections not dealt with adequately by previous researchers.

For example, they aim to clarify the connection between the origins and development of African-American religion and capitalism. Their conceptual framework is "social scientific" (xii) and their approach is "methodological agnosticism" (xiii). They honor the variety of expression and practice in their field by providing "the first comprehensive overview that covers this period and attempts to recognize the diversity of forms that African-American religion takes" (xii). They refer to themselves ..."

"This paper will analyze the book, Don't Say Yes When You Want to Say No by authors Herbert Fensterheim, Ph.D, and Jean Baer. The discussion will focus on some of the important techniques used in assertiveness training.

Author Jean Baer begins the book by sharing how she spent 18 years in an unpleasant job because she did not think that any other employer would hire her. After meeting her husband and co-author, Herbert Fensterheim, a clinical psychologist who specializes in behavior therapy, Baer explains that, by using her husband's behavioral therapy techniques, she learned how to be successfully self-employed and is no longer defensive when her friends say things like "Anybody could write the books you write, you just sit down and do them, that's all" (13-16). Thus, the..."

Abstract
The paper discusses how video games and the video game industry have become as ubiquitous as any everyday gadget. The paper examines how many of the higher powered personal computers are purchased by "gamers" who want the fastest equipment, to power the latest cutting-edge games. The paper further examines how modern games are some of the most demanding on PC resources, so the latest hardware is often targeted at the sector that is most likely to purchase and make use of the latest features.

From the Paper
"Although the video game actually started with the "boob-tube" or television, it has evolved into a completely rewarding and challenging tool. As a point of reference, video games and its historical innovations have been subdivided into seven generation: "First Generation, 1972 - 1977; Second Generation, 1977 - 1981 (Golden Age); Third Generation, 1981 - 1984 (Dark Ages); Fourth Generation, 1985 - 1989 (Post-Crash - 8-bit era); Fifth Generation, 1989 - 1995 (16-bit era); Sixth Generation, 1995 - Present (32/64-bit era); and Seventh Generation, The Future.

Abstract
This paper looks at several approaches by different authorities regarding assertive behavior and the role it has in improving self-esteem. The paper then draws conclusions about the improvement of self esteem based on the information that is presented.

From the Paper
"One way that a person can improve his or her self esteem is to practice assertive behavior. Assertive behavior can be defined as the ability to maintain control over a person's behavior and emotions in order to achieve the goals, results, or communications that he or she seeks. behavior is not aggressive and manipulative. Assertive actions are based on reason and self-awareness rather than as an emotional response to a situation. The authors of the book Don't Say Yes When You Want to Say No state, "People with Excitatory Personalities do not fear their feelings. Frightened neither of closeness not combat, they act out of strength. The excitatory man knows who he is, what he wants. He is assertive" (17). The individual's strength is used to communicate needs and ideas rather than coercing other people. Traditional theories such as those of authors H. Fensterheim and J. Baer have several valid concepts, but they have limitations."

Abstract
This paper takes a look at the method of descriptive analysis and assessment. According to the paper, descriptive analysis can provide useful solutions in terms of individual behavior analysis and observation. There are various descriptive analysis techniques, which this paper reviews and discusses.

From the Paper
"As such, related to observance and the difficulties that occur in such situations, Kazdin brings into question and discusses the nature of the observation, in terms of realism, accuracy and convention ((Kazdin, 1977)). Indeed, descriptive analysis relies on one of the essential tools: observation. If we look at the descriptive assessment as an evaluation of the "how", observing and recording how this "how" will determine the eventual outcome of the analysis. The problem that Kazdin is debating is the existence of a multiple number of observers and, more importantly, the complexity deriving from having different observations and from checking their reliability. The accuracy of the observation is one of the main issues to be discussed when referring to the challenges and implementation of descriptive analysis. "
