An Evaluation of Physical Fitness Parameters for Graduate Students

Abstract

Although graduate physical therapy students are taught the principles of fitness for incorporation into their professional lives, they have difficulty finding the time to implement these principles during graduate school. The authors studied 3 successive classes of graduate physical therapy students at the beginning and ending of their respective programs. They found that the women's percentages of body fat were significantly greater over the period of the study. The men's lower extremity strength decreased at the slower speeds (60 degrees/second), and the women showed increased strength at the higher speeds (180 and 240 degrees/second, respectively). Male grip strength significantly increased over the period of the study. To decrease students' percentages of body fat and increase their strength, the authors asserted that physical therapy students should be allowed more time to participate in fitness activities during their graduate school years.     

Social ecological complex adaptive systems: a framework for research on payments for ecosystem services

The environment is both a setting for and a product of human interactions. Understanding the dynamic nature of human-environment interactions is critical for mitigating the impacts of human induced environmental change and understanding how the environment shapes social systems. Current research has focused on the reduced ability of many natural systems to provide ecosystem services and the subsequent impact on human well-being. Furthermore, there has been a proliferation of cases analyzing the impacts of payment programs designed to enhance ecosystem services. However, analyses that link environmental policies through to their ecological results are not common and methods to do so are not thoroughly developed. To better analyze these interactions, a theory or framework is necessary. This article presents a framework of social ecological complex adaptive systems (SECAS). The framework links structuration theory from social science with the theories of complex adaptive systems from ecology to provide an enhanced understanding of the human drivers and responses to environmental change. The framework is presented as a recursive process where social and ecological systems are both the medium for and product of social action and ecological disturbance. A case study of Costa Rica’s ecosystem service payment program is presented as a demonstration of empirical applicability. This framework is proposed as a method to evaluate payments for ecosystem services, conservation policies, urban ecosystems, and for land use change in general.     

MAKING A NAME IN GAMES

This article explores the development and implementation of a Toronto-based incubator supporting local women in developing their own games. The incubator was created to help change the current (male-dominated) status quo of game production, promising participants skills sharing, support for the development of a new game, and entry into the local community of indie games developers. It was at the same time part of a large network of commercial and non-commercial interests with a shared agenda of promoting the local digital innovation scene. These different motivations and actors are considered to understand the nature of this complex social network market and the circulation of particularly feminized affective labour therein, detailing how value, reward, and benefit are conceptualized throughout this network. The article focuses on how and where these understandings are in alignment and where they fall apart, revealing problematic structures of power and control linked in particular to gender and entrepreneurialism in the area of digital innovation.     

Comparing Ourselves to Others: International Knowledge and Attitudes

The authors focus on the collaboration between a university methods professor and two classroom teachers in teaching social studies methods as a way of bridging the gap between university preparation for teaching social studies and putting that preparation into practice in elementary classrooms. The teachers offer recommendations from their own teaching experiences for how preservice teachers can find time for powerful social studies teaching despite pressures to meet the requirements of No Child Left Behind in literacy and mathematics. They integrate social studies with literacy and math, use "teachable moments" and transitions between subjects, and incorporate social studies research with computer and media skills. In addition, they employ class meetings to practice the democratic processes of collectively setting and revising class rules, accepting responsibility for those rules, and working together to solve classroom problems. Informal feedback from the preservice teachers reflects their appreciation of advice from classroom teachers with current experience in addressing the challenge of making time for powerful social studies teaching.     

Changing compatibility of cohabitation and childbearing between young British women born in 1958 and 1970

We investigate the effect of parenthood on whether non-marital unions led to marriage or parting for two cohorts of British women when they were aged between 16 and 29. We compare the effect of conceptions leading to births and the presence and characteristics of children on the odds that a cohabitation was dissolved, or that it was converted to marriage, for women born in 1958 and 1970. A multilevel, multiprocess, competing-risks model allows for multiple cohabitations per woman and endogeneity of fertility status. We find that cohabiting couples’ response to impending parenthood and the presence of children changed over time. In particular, the proportion of cohabiting couples who married before a birth decreased and, in the 1970 cohort only, the risk of dissolution declined during pregnancy. There is also evidence that the presence of a child cemented a cohabiting union for women from the 1970, but not the earlier, cohort.     

The relationship between childbearing and transitions from marriage and cohabitation in Britain

In this article, we describe a general framework for the analysis of correlated event histories, with an application to a study of partnership transitions and fertility among a cohort of British women. Using a multilevel, multistate competing-risks model, we examine the relationship between prior fertility outcomes (the presence and characteristics of children and current pregnancy) and the dissolution of marital and cohabiting unions and movements from cohabitation to marriage. Using a simultaneous-equations model, we model these partnership transitions jointly with fertility, allowing for correlation between the unobserved woman-level characteristics that affect each process. The analysis is based on the partnership and birth histories that were collected for the 1958 birth cohort (National Child Development Study) aged 16-42. The findings indicate that preschool children have a stabilizing effect on their parents 'partnership, whether married or cohabiting, but the effect is weaker for older children. There is also evidence that although pregnancy precipitates marriage among cohabitors, the odds of marriage decline to prepregnancy levels following a birth.     

When Twenty-Four Hours is not Enough: Time Poverty of Working Parents

Individuals can be money poor, time poor or both. While income is the most used indicator of poverty, broader indexes including non-monetary aspects of deprivation have been proposed and measured. As one such measure, our study focuses on the element of deprivation arising from the time deficit of many working people. The usual poverty threshold is calculated as the amount of income to buy the minimum required goods and services from the market. This minimum required purchase is greater for these people since they have less time than the average person to produce some goods and services for themselves at home. So, they need money to buy these in the market in order to maintain the same consumption. The income standard must be supplemented to adequately measure actual poverty. Time use data make it possible to establish time requirements and time availability and provide a measure of time poverty. Using Canadian GSS 1998 data, and building on the work of Vickery (1977, ‚The time poor: A new look at poverty’, The Journal of Human Resources 12(1), pp. 27-48) and of Douthitt (1993, ‚The inclusion of time availability in Canadian poverty measures’, Time-Use Methodology: Toward Consensus (ISTAT, Roma), pp. 83–91), and our own previous study, we estimate time-adjusted poverty thresholds and rates for single and dual parent Canadian families. As expected, we have found high incidence of time deficit among the employed single parents with children. We make a case for the acceptance of a redefined poverty standard for such time-deprived groups.     

The moderating effect of threat on the relationship between population concern and environmental concern

Two hundred sixty-one research participants completed a questionnaire designed to measure concern for the environment and concern for population growth. The introduction to the questionnaire focused on either threat to society, personal threat, or no threat. Contrary to some previous research findings, a positive correlation between concern for the environment and concern for population growth was found. This finding is explained by the simultaneity of measurement of the two constructs, item phrasing, and the possibility that previous research findings lacked transhistorical reliability. The threat manipulation was found to moderate the relationship between concern for the environment and concern for population growth. Analyses of demographic variables showed that women expressed more environmental concern that men, and that regular church attendees expressed the least concern for population growth.
