IN SEARCH OF WORKING-CLASS IDEOLOGY: A TEST OF TWO PERSPECTIVES*

This article begins as a test of two types of explanation of working-class consciousness. The first focuses upon structural factors. The second identifies nonwork variables as the critical determinant of workers' consciousness. Based on information collected from manual workers in two plants in Edmonton, Canada, the present research finds that neither perspective emerges as a significant determinant of worker ideology. The second part of the article addresses this issue and offers an explanation of the failure to account for much of the variation in workers' ideological thinking.     

Uniform stochastic ordering and related inequalities

Stochastic order between univariate random variates may be called uniform when such order persists under conditioning to a broad family of intervals. The ordering is local when it holds for any finite interval (a, b), however small. Local order in multivariate settings has been described by Whitt (1980, 1981), by Karlin and Rinott (1980), and by others. The prevalence of uniform and local order in a variety of simple stochastic-process settings is displayed, and inequalities arising from such orderings developed.     

The influence of sex,temperament, risk-taking and mental health on the emergence of gambling: a longitudinal study of young people

There are a host of complex and interlinked psychological, social and biological factors involved in the development of problem gambling (PG). While existing research, which is predominantly cross-sectional, shows that emerging adulthood is a critical period for PG, the early risk factors for PG are currently unknown. Here, we recruited a sample of 156 early adolescents with no history of PG (mean age 12.6 years) and longitudinally followed them up into late adolescence (mean age 18.9 years) to investigate the role of sex, risk-taking behaviour and changes in temperament and psychiatric symptoms in the evolution of risky gambling behaviour. There were sex-independent effects of temperament and risk-taking behaviour, with greater developmental increases in temperamental frustration (i.e. negative affectivity), greater developmental decreases in temperamental attention (i.e. effortful control) and greater involvement in risky behaviours, such as alcohol use, predicting greater likelihood of being in the risky gambling group. In addition, there were sex-dependent effects whereby higher levels of baseline aggression in females and lower levels of the same in males were more predictive of risky gambling. These findings highlight how sex-dependent and independent factors across the early- to mid-adolescent period influence the occurrence of gambling later in life.     

Elections,Repertoires of Contention and Habitus in Four Civil Society Engagements in Malaysia's 2008 General Elections

The general elections in Malaysia in 2008 saw the ruling coalition, which has ruled Malaysia uninterrupted since independence in 1957, lose control of a number of states and become significantly weakened at the federal level. Amongst the reasons often cited for this was significant and diverse civil society participation in these elections which was often critical of the incumbent government. This article examines four different engagements in the 2008 elections by civil society actors. Through this examination, it is demonstrated that distinctions between types of collective action, from social movements to political parties, are especially likely to be blurred in the context of repressive states such as Malaysia. This examination in turn sees Charles Tilly's concept of repertoires of contention defended against both Nick Crossley's criticisms of it and his preference of Pierre Bourdieu's concept of habitus.     

“a Difficult Life”: The Perceptions and Experience of Poverty in South Africa

The purpose of this article is to provide a fuller and more integrated understanding of poverty based on the results of a nation wide participatory study recently completed in South Africa. A surprisingly consistent view of poverty emerges from the study which includes social isolation, malnourished children, crowded homes, the use of basic energy sources, no employment, and fragmented households. A clear image of what results from extreme poverty also emerges comprising continuous ill health, arduous and often hazardous work for virtually no income, no power to influence change, and high levels of anxiety and stress. The article concludes that conventional definitions of poverty do not fully describe the experience of poverty as analysed by the poor themselves. Instead, the multidimensional nature of poverty suggests that three basic concepts would be useful in any analysis of extent, nature and persistence of poverty. These are sufficiency, access and vulnerability.     

Volunteers, families and children in need: an evaluation of Family Friends

This paper explores the findings from a small‐scale research project that analysed the impact of Family Friends – a voluntary agency that provides support to families under stress who have children aged between 5 and 11 years. The study, funded by Family Friends, evaluated service users’ perceptions of the support they received, specifically in relation to the significance and impact of the volunteer befrienders. The research identified that there are a proportion of families in need who fail to attract services from mainstream statutory agencies. It also identified that the Family Friends voluntary agency makes a particular contribution to service provision by offering a friendly, non‐stigmatizing, caring and responsive service.     

Awareness and use of a university recreational trail

The purpose of this study was to assess awareness and use of a university recreational trail. The authors used an Internet questionnaire developed by the university's Institutional Research Department, with questions derived from the Environmental Supports for Physical Activity Questionnaire and the National College Health Risk Behavior Survey Physical Activity Module. Four hundred and sixty-seven undergraduate college students participated. Ninety-one percent of students reported being aware of the trail, and 73% reported using the trail. Sixty-four percent of students reported seeing signage referring to the recreational trail. Sixty-seven percent of the students reported using the trail once in the past week, 7% reported using the trail twice in the past week, and only 2% of the students reported using the trail more than 3 times in the past week. Sixty-two percent reported using the trail with another individual. Students who were aware of the trail were more likely to use the trail. However, of the individuals who used the trail, the majority only used the trail 1 day a week. University programming is needed to increase trail usage among college students.     

Anticolonial thought,the sociological imagination,and social science: A reply to critics

Sociology was born in the late 19th and early 20th centuries as a project in, of, and for empire. This essay excavates a tradition of social thought that grew alongside metropolitan sociology but has been marginalized by it: anticolonial thought. Emerging from anticolonial movements, writers and thinkers, anticolonial thought in 19th and 20th centuries emerged from a variety of thinkers (from indigenous activists in the Americas to educated elites in the American, Francophone and British colonies). I argue that this body of thought offers distinct visions of society, social relations, and social structure, along with generative analytic approaches to the social self, social solidarity and global relations—among other themes. Anticolonial thought offers the basis for an alternative canon and corpus of sociological thinking to which we might turn as we seek to revitalize and decolonize sociology.     

Social investments in the knowledge economy: The politics of inclusive,stratified, and targeted reforms across the globe

As countries transition from industrial to post-industrial knowledge economies, education and skills are crucial. Consequently, policy-makers around the globe have increasingly focused on social investment, that is, policies aiming to create, mobilize, or preserve skills. Yet, countries around the globe have developed social investments to different degrees and in highly different forms. Our goal is twofold: First, we introduce a new typology of social investment policies, distinguishing nine types along two dimensions: three distributive profiles (inclusive, stratified, targeted) and three functions (skill creation, preservation, mobilization). This differentiation allows fine-grained analyses of the causes and consequences of different kinds of social investments, thus offering a perspective to study the relationship between efficiency and inclusiveness in a way that goes beyond the mere discussion how social investment policies grosso modo affect inequalities (‘equalizing’ versus ‘Matthew Effects’). Second, we theorize on the politics of social investment. We argue that the interaction of policy legacies and socioeconomic factors is the main explanation for which functions of social investment policies are introduced, whereas their distributive profiles are crucially shaped by political coalitions. We illustrate with empirical material from democracies around the globe.
