Developing a Program in Sociological Practice: Program Structure,Curriculum Design,and Professional Culture

A sociological practice program has much to offer an undergraduate sociology department that wishes to make itself more relevant to its students, university, and larger community. Reasons are explored for why a department might choose to transform its program from a more traditional liberals arts focus to that of sociological practice. A discussion of the programmatic content of a practice program, including structure, curriculum design, and professional culture, is detailed. The experience of Our Lady of the Lake University in developing its accredited undergraduate sociological practice program is offered as an example of program development.

Racial and sex differences of fruit and vegetable self-efficacy and intake among college students in a rural,southern location

Abstract

Objective: To examine fruit and vegetable intake and self-efficacy among U.S. college students in a rural, Southern location. Participants: Undergraduate students (n?=?1503) enrolled in a university-wide health class at one large public institution during the spring 2017 semester. Methods: Cross-sectional survey data were collected online and analyzed using independent samples t test, one-way ANOVA, and regression. Results: On average, participants did not meet fruit or vegetable intake recommendations. Mean self-efficacy scores were 17.2 (SD?=?3.4) and 16.42 (SD?=?3.7) for fruit and vegetables, respectively, with statistically significant differences observed by sex and race (p?<?0.05). Hierarchical multiple regression results indicated self-efficacy explained 20.9% (fruit) and 29.3% (vegetables) of the variance in consumption. Similar patterns were found for meeting daily fruit and vegetable intake recommendations. Conclusions: Health campaigns are needed to address sex and racial disparities in college student fruit and vegetable intake and self-efficacy.     

Playing the Numbers Game

Nonprofit organizations are often evaluated using the program ratio: the proportion of mission‐related program expenses to total expenses. Nonprofit managers have incentives to manipulate the reporting of financial information to enhance the program ratio. This article reviews the scholarly literature on program ratio management in nonprofit organizations. Prior research has identified several motivations for and methods of program ratio management and provided limited evidence that it occurs. Researchers have explored the consequences of program ratio management and provided a list of factors mitigating such behaviors. The emerging consensus is that the program ratio is of limited usefulness in evaluating nonprofit performance.     

Negotiating independence,choice and autonomy: experiences of parents who coordinate personal assistance on behalf of their adult son or daughter

Article 19 of the UN Convention on the Rights of Persons with Disabilities requires states to provide personal assistance services. This article is based on qualitative research in Iceland, Norway and Sweden, carried out between 2012 and 2013. The overall study focused broadly on the implementation of Article 19. This article, however, reports findings based on a particular group of participants within the larger study: non-disabled parents who coordinate personal assistance schemes for their adult son or daughter. The article examines the various ways in which the parents, the majority of whom were mothers, negotiate principles of independence, choice and autonomy for their adult son or daughter who requires intensive support, including assistance with communicating. The aim is to explore, in the context of the Convention and the principles of the independent living movement, how to acknowledge and conceptualise personal assistance schemes that require another person to manage on behalf of the user.     

Understanding the link between poverty and food insecurity among children: Does the definition of poverty matter?

This paper examines the association between poverty and food insecurity among children, using two different definitions of poverty – the official poverty measure (OPM) and the new supplemental poverty measure (SPM) of the Census Bureau, which is based on a more inclusive definition of family resources and needs. Our analysis is based on data from the 2001–2011 Current Population Survey and shows that food insecurity and very low food security among children decline as income-to-needs ratio increases. The point estimates show that the associations are stronger as measured by the new supplemental measure of income-to-needs ratio than when estimated through the official measure. Statistical tests reject the hypothesis that poor households' odds of experiencing low food security are the same whether the SPM or OPM measure is used; but the tests do not reject the hypothesis when very low food security is the outcome.     

Social assistance in Austria: regulating the poor as in-between

Not only the concept of social inclusion is widely recognized as an important basis today for making social policy, but it also provides a platform for the policing of the poor. Thinking uncritically about social inclusion prevents us from seeing how it operates to re-inscribe subordination even as we help the poor overcome their marginalization. With an awareness of the paradox of inclusion, it is possible to examine how welfare policy today operates to discipline the poor as people who must accept their plight at the bottom of the socioeconomic order. While formal policy may not make this paradox apparent, the disciplinary effects of an inclusionary social assistance policy are starkly visible when we examine its implementation, where we can see how the excluded become included in ways that perpetuate their subordination. Social assistance recipients obtain a benefit, but the way they are treated does not correspond with full social rights, which is reminiscent of Georg Simmel's discussion of the poor. As exemplified by research at one local social assistance office in Austria, welfare recipients are ultimately neither included nor excluded. Welfare, as administered today, upholds the system of social stratification by perpetuating an ‘in-between’ status for the claimants of social assistance benefits at the frontline.
