Comparison of till and no-till agricultural practices on carbon dioxide flux from the soil on an organic farm

The utilization of no-till or conservational tillage practices is widely considered to lower carbon dioxide (CO2) emissions. In this study, the effect of till and no-till practices were assessed based on the CO2 flux from the soil on an organic farm located in upstate South Carolina. The measurements were taken over a month long period in late fall. The no-till plot had been recently converted and the till plot had been harvested in the months prior. In addition to studying the CO2 flux, temperature data was recorded for comparison. At temperatures below 45°F, the CO2 flux from the till plot was lower than from the no-till plot. While these findings were helpful, they raised questions. The study was repeated with different comparisons. The plots were compared to ambient outputs, and the results favored the no-till plot. Overall, no-till output of CO2 was lower than the till plot. These findings support the implementation of no-till practices as a method of reducing atmospheric CO2

The Jack Sprat Low-Fat Diet: A 28-Day Heart-Healthy Plan You Can Follow the Rest of Your Life

This exciting work by a nationally known fitness and health expert is a realistic and practical guide to a healthier and happier lifestyle. Dr. Bryant Stamford, author of the highly acclaimed Fitness Without Exercise and a syndicated health columnist, and co-author Becca Coffin, a registered nurse, show how making the right choices in diet can improve health and reduce fat while allowing people to enjoy a fuller and more varied diet than other weight-loss plans permit. Americans are obsessed with diets and dieting, and yet we grow fatter every year. Traditional diets offer only temporary weight loss through loss of water and muscle and do not address the real problems of dietary fat and poor eating habits. Fat is sinister, wreaking havoc on every system of the body. Eating fat results in fat people, but it also clogs the arteries, raises blood pressure, overloads the bowels, and causes diabetes. To avoid the dangers of dietary fat, we need to change our eating habits. Happily, we don\u27t have to eat less; we just need to make smarter choices about what we eat. The Jack Sprat diet plan uses a guided day-by-day approach geared to gender, size, and physical activity level. Each of the four weeks in the plan starts with a complete grocery list, including daily menus that have been analyzed to show how many calories and grams of fat will be consumed. All menus have been analyzed also to assure fulfillment of RDA guidelines. Recipes are provided for all home-prepared items in the plan, and specially designed On-Your-Own tables help with substitutions in the daily menus. There are even sections for including fast foods and a system of controlled cheating. To help ensure success, Stamford and Coffin provide not only day-by-day and meal-by-meal details of what to eat but also insightful scientific background that explains why. These chapters include information on how much fat one should eat, how to make smart choices when choosing a menu, and the benefits of light exercise. The authors also present a wealth of more specific information on physiology and metabolism, hormones, antioxidants, and phytochemicals, as well as on frauds such as cellulite-reducing creams and diet pills. Stamford and Coffin do not offer miracles or magic, but they do provide sound advice and practical guides that will be invaluable to anyone interested in losing weight and making positive lifestyle changes. Bryant A. Stamford is a nationally recognized expert in the field of health and fitness. He is director of the Health Promotion Center at the University of Louisville and the author of Fitness Without Exercise as well as a nationally syndicated column called Body Shop. His column titled Exercise Adviser runs in the journal The Physician and Sports Medicine, and he is an editorial advisor to a number of popular publications, including Prevention and Men\u27s Health. Becca Coffin is a registered nurse at the Health Promotion Center who has worked with Dr. Stamford for many years to develop the Jack Sprat low-fat diet plan. She writes a monthly health and fitness column for Today\u27s Woman.https://uknowledge.uky.edu/upk_medicine_and_health_sciences/1009/thumbnail.jp

E-conferencing: Corpus and Discourse Insights

A selection of recent work by experts in academic written discourse illustrates how corpus linguistics and discourse analysis can work as complementary approaches

Learning the language of school history: the role of linguistics in mapping the writing demands of the secondary school curriculum

This paper reports on a research study which used the tools of functional linguistics to illuminate the writing requirements of the history curriculum in the context of Australian secondary schools. It shows how the resulting linguistic description was integrated into a sequence of teaching and learning activities through collaboration between linguist specialists and content/pedagogic specialists. These activities were designed to facilitate students’ writing skills whilst simultaneously developing their historical knowledge. An independent evaluation of the approach pointed to positive changes in teachers’ attitudes and behaviours regarding the role of language in learning history. Equally, students’ writing improved, particularly in terms of its organisation and structure

Using exchange structure analysis to explore argument in text-based computer conferences

Computer conferencing provides a new site for students to develop and rehearse argumentation skills, but much remains to be learnt about how to encourage and support students in this environment. Asynchronous text-based discussion differs in significant ways from face-to-face discussion, creating a need for specially designed schemes for analysis. This paper discusses some of the problems of analysing asynchronous argumentation, and puts forward an analytical framework based on exchange structure analysis, which brings a linguistic perspective to bear on the interaction. Key features of the framework are attention to both interactive and ideational aspects of the discussion, and the ability to track the dynamic construction of argument content. The paper outlines the framework itself, and discusses some of the findings afforded by this type of analysis, and its limitations

The Process of Ending Domestic Violence among Latinas: Aguantando No Mas

The purpose of this study was to explore the sociocultural factors which play a role in the process of ending an abusive relationship among Latinas. Dimensional analysis was the method employed for the development of a grounded theory. Aguantando or enduring emerged from this study as pivotal in gaining an understanding of the process of ending an abusive relationship for Latinas. Participants indicated that personal and religious beliefs, the importance of family, and the needs of their children were reasons for aguantando or enduring the abuse. The decision to no longer aguantar, or endure, occurred through a series of encounters with allies , the loss of hope their partner was going to change his abusive behavior, and the final realization that the well-being of the children was being affected by the abuse. These conditions led Latinas to take action by hasta aqui or drawing the line. Through their relationships with allies, Latinas recognized their potential to salir adelante or forge ahead. Findings in this study indicate that familialism played a major role in the decision to stay or leave an abusive relationship. Family members supported Latinas leaving their abusive partners. Latinas often did not initiate plans to end an abusive relationship until effects of the abuse became evident in the children\u27s behavior. Interventions and outreach programs integrating these findings are proposed for the Latino community. Future research investigating the applicability of current theoretical models of domestic violence to the Latino population are proposed
