The objective of the present study was to investigate the effects of combined training without caloric restriction on inflammatory markers in overweight girls. Thirty-three girls (13–17 years) were assigned into overweight training (n = 17) or overweight control (n = 16) groups. Additionally, a normal-weight group (n = 15) was used as control for the baseline values. The combined training programme consisted of six resistance exercises (three sets of 6–10 repetitions at 60–70% 1 RM) followed by 30 min of aerobic exercise (walking/running) at 50–80% VO_2peak, performed in the same 60 min session, 3 days/weeks, for 12 weeks. Body composition, dietary intake, aerobic fitness (VO_2peak), muscular strength (1 RM), glycaemia, insulinemia, lipid profile and inflammatory markers (C-reactive protein, interleukin-6, tumour necrosis factor-alpha, interleukin-10, leptin, resistin and adiponectin) were measured before and after intervention. There was a significant decrease in body fat (P < 0.01) and increase in fat-free mass (P < 0.01), VO_2peak (P < 0.01), 1 RM for leg press (P < 0.01) and bench press (P < 0.01) in the overweight training group. Concomitantly, this group presented significant decreases in serum concentrations of C-reactive protein (P < 0.05) and leptin (P < 0.05), as well as in insulin resistance (P < 0.05) after the experimental period. In conclusion, 12 weeks of combined training without caloric restriction reduced inflammatory markers associated with obesity in overweight girls.  相似文献   

Enhancing Teaching and Learning: Libraries and Open Educational Resources in the Classroom     

Erin Davis  Dory Cochran  Britt Fagerheim  Becky Thoms 《Public Services Quarterly》2016,12(1):22-35

Academic libraries continually adjust services to adapt to the ever-changing landscape in higher education. In response to the broken textbook market, libraries are becoming actively involved in the open educational resources (OER) movement. Although there is not a formal program in place, librarians at Utah State University explored a collaborative approach to integrate OER in faculty members' courses. One goal of the effort was to work closely with faculty to consider course objectives and learning outcomes when evaluating and incorporating OER. This article identifies a streamlined process for targeting courses most suited for OER adoption and outlines a process of collaborating with teaching faculty to integrate relevant OER. The paper includes a detailed workflow that other libraries can easily adapt to make OER part of their faculty outreach toolkit.  相似文献   

Teaching human genetics with mustard: rapid cycling Brassica rapa (fast plants type) as a model for human genetics in the classroom laboratory     

Wendell DL  Pickard D 《CBE life sciences education》2007,6(2):179-185

We have developed experiments and materials to model human genetics using rapid cycling Brassica rapa, also known as Fast Plants. Because of their self-incompatibility for pollination and the genetic diversity within strains, B. rapa can serve as a relevant model for human genetics in teaching laboratory experiments. The experiment presented here is a paternity exclusion project in which a child is born with a known mother but two possible alleged fathers. Students use DNA markers (microsatellites) to perform paternity exclusion on these subjects. Realistic DNA marker analysis can be challenging to implement within the limitations of an instructional lab, but we have optimized the experimental methods to work in a teaching lab environment and to maximize the “hands-on” experience for the students. The genetic individuality of each B. rapa plant, revealed by analysis of polymorphic microsatellite markers, means that each time students perform this project, they obtain unique results that foster independent thinking in the process of data interpretation.  相似文献   

Organization and visualization for initial analysis of forced-choice ipsative data     

Jill A. Cochran 《International Journal of Research & Method in Education》2015,38(4):413-429

Forced-choice ipsative data are common in personality, philosophy and other preference-based studies. However, this type of data inherently contains dependencies that are challenging for usual statistical analysis. In order to utilize the structure of the data as a guide for analysis rather than as a challenge to manage, a visualisation tool was developed to emphasize the established framework and enhance analysis tools. This visualisation has many strength, including the display of significant amounts of data at once in three dimensions with little loss of detail, incorporating the theoretical framework for the data into the structure of the visualisation and organizing the data for use with common statistical tests and analysis tools.  相似文献

Prevalence of childhood sexual abuse among incarcerated males in county jail     

Johnson RJ  Ross MW  Taylor WC  Williams ML  Carvajal RI  Peters RJ 《Child abuse & neglect》2006,30(1):75-86

OBJECTIVE: The current study examined the prevalence and characteristics of childhood sexual abuse in a jailed-based population. METHODOLOGY: A retrospective, self-reported survey was administered over an 8-week period to a random sample of 100 men who were incarcerated in a county jail in Southeastern Texas. The survey included questions about childhood sexual experiences before and after puberty, drug history and use, and sexual risk-taking behaviors. RESULTS: Of the 100 male inmates who participated in this study, 59% reported experiencing some form of sexual abuse before puberty, and all such instances occurred before or at the age of 13 years. The first episode of childhood sexual abuse began at an average age of 9.6 years (SD = 2.4), and ended at an average age of 13.0 years (SD = 2.3). Kissing and touching without intercourse (64%) was the common pattern of sexual abuse experience reported. The total number of perpetrators was 165, with 10% male and 90% female. Friends (n = 72) and family (n = 56) were the most frequent perpetrators. CONCLUSION: Childhood sexual abuse may be more prevalent among inmates than among males in the general population. These results show a high percentage of inmates who report a history of childhood sexual abuse; this rate is higher than those reported by other studies for incarcerated males. The findings support the belief held by professionals in the criminal justice field that a significant number of incarcerated males may have been victims of sexual abuse.  相似文献   

Profiles in Change: An Alternative Look at the Marshall Hypotheses∗     

John K. Cochran  Beth Sanders  Mitchell B. Chamlin 《Journal of Criminal Justice Education》2013,24(2):205-226

U.S. Supreme Court Justice Thurgood Marshall once argued that informed opinion would oppose the death penalty for all but those who support it for retributive reasons. We examine the validity of these claims with data from a series of one‐group pre‐test–post‐test designs which stem from a formalized learning outcomes assessment for several courses on the death penalty. Results show solid, but imperfect, support for these claims. The analysis then proceeds by profiling those who changed their opinions consistent with these claims, those who did not change their opinions, and those whose opinions changed in a manner opposite to these claims.  相似文献   

Implementing New York's Universal Pre-Kindergarten Program: An Exploratory Study of Systemic Impacts     

Taryn W. Morrissey  Kristi S. Lekies  Moncrieff M. Cochran 《Early education and development》2013,24(4):573-596

This exploratory study examined the impacts of New York's Universal Pre-kindergarten (UPK) program as perceived by directors at child care centers and preschools not receiving state funds. Although only partially implemented, UPK's mixed-delivery system grants monies to a substantial number of qualifying community-based early care and education centers, resulting in a funding imbalance between participating and nonparticipating centers. Phone interviews were conducted with the directors of non-UPK programs across New York State (N = 46). Quantitative and qualitative analyses suggest perceived decreases in 4-year-old and total enrollment and increased teacher recruitment difficulty and competition for teachers since UPK was introduced. Larger centers and those offering full-day programming more often reported changes in teacher recruitment and retention than smaller centers and those offering part-day programming only. Implications for state pre-K policy are discussed.  相似文献

Defining the outcomes of teacher education: what's social justice got to do with it?     

Marilyn Cochran‐Smith 《Asia-Pacific Journal of Teacher Education》2004,32(3):193-212

In the context of escalating criticism of university‐based teacher education across the world, a clear need exists for informed defence of the field and the profession as well as critical evaluation of both teacher education and schooling. This paper takes up the issue of the ‘outcomes question’ in this regard, arguing the case for a strong focus on social justice as the necessary complement to an ongoing concern with academic excellence and rigor. It argues the need for teacher educators and others to look closely at the different ways that educational outcomes are currently being defined and for these differences to be made more openly and widely available for criticism and discussion. The paper seeks to contribute to debate regarding the role and renewal of teacher education, in specific relation to widespread standards movements and the public good, and the conduct and governance of education more generally.  相似文献
