Molecular phylogeny of the animal kingdom

Abstract: A rapid sequencing method for ribosomal RNA was applied to the resolution of evolutionary relationships among Metazoa. Representatives of 22 classes in 10 animal phyla were used to infer phylogenetic relationships, based on evolutionary distances determined from pairwise comparisons of the 18S ribosomal RNA sequences. The classical Eumetazoa are divided into two groups. Cnidarians arose from a protist ancestry different from the second group, the Bilateria. Within the Bilateria, an early split gave rise to Platyhelminthes (flatworms) and the coelomate lineage. Coelomates are thus monophyletic, and they radiated rapidly into four groups: chordates, echinoderms, arthropods, and eucoelomate protostomes.

A meta-analysis of the past 25 years of weight loss research using diet, exercise or diet plus exercise intervention

Abstract: OBJECTIVE: The therapeutic effectiveness of diet, exercise, and diet plus exercise for weight loss in obesity was determined. DATA SOURCES: All human research reported in English, published in peer-reviewed scientific journals within the past 25 y was reviewed. STUDY SELECTION: Acceptance criteria (na 493 from> 700 studies) were that a therapeutic intervention of diet, exercise or diet plus exercise was employed, specifically for weight reduction in obese adult humans and that weight change was reported numerically. Only aerobic exercise studies were included, while drug, hormone and surgical treatments were excluded. DATA EXTRACTION: All data were extracted by the same investigator from the original research report. Except for gender and program type, all extracted data were numerical. DATA SYNTHESIS: ANOVA, with a Newman‐Keuls post hoc test, was used to determine differences among programs (P< 0.05). One analysis was performed on the group mean data and one based on effect sizes. Analyses were repeated using initial body weight, initial percent body fat and program length, as covariates. RESULTS: Primarily, subjects aged 40 y have been studied (39.5 0.4 y, mean s.e.m.) who are only moderately obese (92.7 0.9 kg, 33.2 0.5 body mass index (BMI), 33.4 0.7% body fat); for short durations (15.6 0.6 weeks). Exercise studies were of a shorter duration, used younger subjects who weighed less, had lower BMI and percentage body fat values, than diet or diet plus exercise studies. Despite these differences, weight lost through diet, exercise and diet plus exercise was 10.7 0.5, 2.9 0.4* and 11.0 0.6 kg, respectively. However, at one-year follow-up, diet plus exercise tended to be the superior program. Effect size and covariate analyses revealed similar program differences. CONCLUSION: Weight loss research over the past 25 y has been very narrowly focused on a middle age population that is only moderately obese, while the interventions lasted for only short periods of time. The data shows, however, that a 15-week diet or diet plus exercise program, produces a weight loss of about 11 kg, with a 6.6 0.5 and 8.6 0.8 kg maintained loss after one year, respectively.

Cultural Imperialism: A Critical Introduction

Abstract: In Cultural Imperialism, John Tomlinson deals with issues ranging from the ideological effects of imported cultural products, to the process of cultural homogenization, to the nature of cultural autonomy. He examines a number of related discourses: thedebate about "media imperialism" the discourse of national cultural identity; the critique of multinational capitalism and the critique of cultural modernity. His analysis reveals major problems in the way in which the idea of cultural, as distinct from economic or political, imperialism is formulated.

Building an integrative model of small business growth

Abstract: The purpose of this article is to develop an integrative model of small business growth that is both broad in scope and parsimonious in nature. Such a “big picture” model provides an opportunity (1) to gauge how much we really know about small business growth, when we simultaneously consider the constructs from the dominant perspectives, (2) to assess the contribution of each of these perspectives, (3) to examine the indirect effects that some constructs from one perspective might have on small business growth through constructs from another perspective, and (4) to consider different levels of analysis. Based on an analysis of data from 413 small businesses, we derive a set of propositions that suggest how entrepreneurial orientation, environmental characteristics, firm resources, and managers’ personal attitudes directly and/or indirectly influence the growth of small businesses.
