Testing Standard Modern Paragraph Theories (Becker, Christensen, Rodgers).

This study tests the relative effectiveness of the standard modern paragraph theories of A. L. Becker, Francis Christensen, and Paul C. Rodgers, Jr., three major theorists contributing more sophisiticated explanations of the form of paragraphs than that of Alexander Bain, whose theory as summarized in the familiar principles of unity, coherence, and emphasis has dominated textbook explanations of paragraphing since the late nineteenth century. In this test the three theories have been applied to fourteen selected professional essays appearing in six of the best-selling composition readers. Of these essays, seven, designated as classical, are written by the most frequently anthologized essayists, and seven, designated as ephemeral, are randomly selected essays with topical appeal. The components of the three theories tested are Becker\u27s tagmemic patterns and four operations for variation, his lexical equivalence classes, lexical transitions, and verb sequences; Christensen\u27s coordinate, subordinate, and mixed sequences and his dictum concerning the topic sentence in the initial position; and Rodgers\u27 concepts of the stadia of discourse and secondary influences on paragraphing. The study presents a summary of the theoretical assumptions of Becker, Christensen, and Rodgers; a summary of the statistical findings of the applications of the three theories; a comparative summary of the conformity and non-conformity of paragraphs reflecting the application of Becker\u27s and Christensen\u27s theories; a justification of the 100% conformity of the paragraphs to Rodgers\u27 theory; and finally some reflections on the applications of the findings to the teaching of college composition. In terms of the overall effectiveness of the three theories in this sample, Becker\u27s theory works 32.8% of the time, Christensen\u27s 30.8%, and Rodgers\u27 100%. The conclusion that can be drawn from the much greater effectiveness of Rodgers\u27 theory is that, with his discourse-centered theory as opposed to Becker\u27s and Christensen\u27s sentence-based theories, Rodgers allows for sequences of discourse not necessarily conterminous with paragraph boundaries and for more flexible concepts of fluctuations in the abstraction levels within sequences. Another conclusion is that Becker\u27s and Christensen\u27s theories, with modifications, could more formally describe the reality of paragraph structure

Helping education undergraduates to use appropriate criteria for evaluating accounts of motivation

The aim of the study was to compare students in a control group with those in a treatment group with respect to evaluative comments on psychological accounts of motivation. The treatment group systematically scrutinized the nature and interpretation of evidence that supported different accounts, and the assumptions, logic, coherence and clarity of accounts. Content analysis of 74 scripts (using three categories) showed that the control group students made more assertions than either evidential or evaluative points, whereas the treatment group used evaluative statements as often as they used assertion. The findings provide support for privileging activities that develop understanding of how knowledge might be contested, and suggest a need for further research on pedagogies to serve this end. The idea is considered that such understanding has a pivotal role in the development of critical thinking

Regulation and the cost of childcare

Female labour market choices depend on the availability, affordability and quality of childcare. In this article, we evaluate different regulatory measures and their effect on both the quality and the cost of childcare. First, we analyse data on regulations and costs to estimate the effect of regulatory measures on the cost of childcare. Next, we summarize the existing literature on the effect of regulation on childcare quality. We find that regulation intended to improve quality often focuses on easily observable measures of the care environment that do not necessarily affect the quality of care but that do increase the cost. Thus, we find that the regulatory environment could be improved by eliminating costly measures that do not affect quality of care

Mas'Queer'Raid

As a creolized Trinidadian subject, I navigate the tensions of my heritage and selfhood as a transgressive queer body. Through a critical engagement with ceramic sculpture I fuse the costumes and characters of Trinidadian Carnival in order to manifest tensions of power, gender, and violence through a conversationalist practice. Utilizing texts on the historical development of Carnival and Trinidad, I form a historical foundation upon which I build critical reflection into my embodied past. The resulting characters are solidified navigations of my selfhood through Carnival. I propose that each character then adds to an expanding critical reflection of Mas/Carnival in Trinidad both at home and abroad

Association of Accelerometry-Measured Physical Activity and Cardiovascular Events in Mobility-Limited Older Adults: The LIFE (Lifestyle Interventions and Independence for Elders) Study.

BACKGROUND:Data are sparse regarding the value of physical activity (PA) surveillance among older adults-particularly among those with mobility limitations. The objective of this study was to examine longitudinal associations between objectively measured daily PA and the incidence of cardiovascular events among older adults in the LIFE (Lifestyle Interventions and Independence for Elders) study. METHODS AND RESULTS:Cardiovascular events were adjudicated based on medical records review, and cardiovascular risk factors were controlled for in the analysis. Home-based activity data were collected by hip-worn accelerometers at baseline and at 6, 12, and 24 months postrandomization to either a physical activity or health education intervention. LIFE study participants (n=1590; age 78.9±5.2 [SD] years; 67.2% women) at baseline had an 11% lower incidence of experiencing a subsequent cardiovascular event per 500 steps taken per day based on activity data (hazard ratio, 0.89; 95% confidence interval, 0.84-0.96; P=0.001). At baseline, every 30 minutes spent performing activities ≥500 counts per minute (hazard ratio, 0.75; confidence interval, 0.65-0.89 [P=0.001]) were also associated with a lower incidence of cardiovascular events. Throughout follow-up (6, 12, and 24 months), both the number of steps per day (per 500 steps; hazard ratio, 0.90, confidence interval, 0.85-0.96 [P=0.001]) and duration of activity ≥500 counts per minute (per 30 minutes; hazard ratio, 0.76; confidence interval, 0.63-0.90 [P=0.002]) were significantly associated with lower cardiovascular event rates. CONCLUSIONS:Objective measurements of physical activity via accelerometry were associated with cardiovascular events among older adults with limited mobility (summary score >10 on the Short Physical Performance Battery) both using baseline and longitudinal data.

Integrated Model of Chemical Perturbations of a Biological Pathway Using 18 In Vitro High Throughput Screening Assays for the Estrogen Receptor

We demonstrate a computational network model that integrates 18 in vitro, high-throughput screening assays measuring estrogen receptor (ER) binding, dimerization, chromatin binding, transcriptional activation and ER-dependent cell proliferation. The network model uses activity patterns across the in vitro assays to predict whether a chemical is an ER agonist or antagonist, or is otherwise influencing the assays through a manner dependent on the physics and chemistry of the technology platform (“assay interference”). The method is applied to a library of 1812 commercial and environmental chemicals, including 45 ER positive and negative reference chemicals. Among the reference chemicals, the network model correctly identified the agonists and antagonists with the exception of very weak compounds whose activity was outside the concentration range tested. The model agonist score also correlated with the expected potency class of the active reference chemicals. Of the 1812 chemicals evaluated, 111 (6.1%) were predicted to be strongly ER active in agonist or antagonist mode. This dataset and model were also used to begin a systematic investigation of assay interference. The most prominent cause of false-positive activity (activity in an assay that is likely not due to interaction of the chemical with ER) is cytotoxicity. The model provides the ability to prioritize a large set of important environmental chemicals with human exposure potential for additional in vivo endocrine testing. Finally, this model is generalizable to any molecular pathway for which there are multiple upstream and downstream assays available

Metabolism within the tumor microenvironment and its implication on cancer progression: an ongoing therapeutic target

Since reprogramming energy metabolism is considered a new hallmark of cancer, tumor metabolism is again in the spotlight of cancer research. Many studies have been carried out and many possible therapies have been developed in the last years. However, tumor cells are not alone. A series of extracellular components and stromal cells, such as endothelial cells, cancer-associated fibroblasts, tumor-associated macrophages and tumor-infiltrating T cells, surround tumor cells in the so-called tumor microenvironment. Metabolic features of these cells are being studied in deep in order to find relationships between metabolism within the tumor microenvironment and tumor progression. Moreover, it cannot be forgotten that tumor growth is able to modulate host metabolism and homeostasis, so that tumor microenvironment is not the whole story. Importantly, the metabolic switch in cancer is just a consequence of the flexibility and adaptability of metabolism and should not be surprising. Treatments of cancer patients with combined therapies including anti-tumor agents with those targeting stromal cell metabolism, anti-angiogenic drugs and/or immunotherapy are being developed as promising therapeutics.Mª Carmen Ocaña is recipient of a predoctoral FPU grant from the Spanish Ministry of Education, Culture and Sport.
