From Structure to Agency to Process: The Evolution of Charles Tilly’s Theories of Social Action as Reflected in His Analyses of Contentious Politics

Charles Tilly’s social theories shifted over the course of his career from an early focus on quantitative and macro-sociological approaches to a later focus on relations and agency. His studies of state-making also shifted, from a focus on conflict and capitalism to explorations of democracy. This paper details these shifts and places them in the context of broader trends in comparative-historical and political sociology.     

Calibration of FI‐ISK,an Invasiveness Screening Tool for Nonnative Freshwater Invertebrates

The Freshwater Invertebrate Invasiveness Scoring Kit (FI‐ISK) is proposed as a screening tool for identifying potentially invasive freshwater invertebrates. FI‐ISK was adapted from the Fish Invasiveness Scoring Kit (FISK) of Copp, Garthwaite, and Gozlan, which is an adapted form of the Weed Risk Assessment (WRA) of Pheloung, Williams, and Halloy. Initial assessments using FI‐ISK, which include confidence (certainty/uncertainty) rankings by the assessor to each response, were calibrated to determine the most appropriate score thresholds for classifying nonnative species into low‐, medium‐, and high‐risk categories, using both the original medium‐to‐high risk threshold scores for the WRA (i.e., ≥6) and for FISK (i.e., ≥19). Patterns of the assessor's confidence, when making the responses during the FI‐ISK assessments, were also examined. Using receiver operating characteristic (ROC) curves, FI‐ISK was shown to distinguish accurately (and with statistical confidence) between potentially invasive and noninvasive species of nonnative crayfish (Decapoda: Astacidae, Cambaridae, Parastacidae), with the statistically appropriate threshold score for high‐risk species scores being ≥16. FI‐ISK represents a useful and viable tool to aid decision‐ and policymakers in assessing and classifying freshwater invertebrates according to their potential invasiveness.     

Putting consumer behaviour in its place: the Behavioural Perspective Model research programme

Consumer research remains overwhelmingly cognitive in orientation, partly because its apparent underlying philosophical stance usually goes unremarked and unchallenged. In so far as scientific progress relies on the interaction of competing theories, consumer research is impoverished by too great a reliance on a single approach to theory. This paper proposes an alternative to the prevailing 'intentional stance' on which consumer research predominantly rests; the 'contextual stance' eschews the intentionality of the cognitive explanations of consumer choice, substituting for it an account of behaviour determined by its environmental consequences. As a prelude to the interactive debate that these competing stances will hopefully engender, the paper demonstrates that the contextual stance is a viable strategy for consumer research. The contextual strategy leads to an alternative model of consumer choice to those based on social cognitive psychology. It is argued that this model of consumer choice in behavioural perspective provides a thoroughgoing conceptual reinterpretation of consumer behaviour and marketing management as currently envisaged.     

Social Support Networks and School Outcomes: The Centrality of the Teacher

This investigation compares school outcomes for students who differ in the extent to which they perceive their parents, friends, and teachers—each alone and in combination—as important sources of social support. Findings indicate that middle and high school students who perceive high supportiveness from all three sources of support, as opposed to none, one, or two, have better attendance; spend more hours studying; avoid problem behavior more; have higher school satisfaction, engagement, and self-efficacy; and obtain better grades. Positive school outcomes are promoted when teacher support is perceived in combination with perceived support from parents and friends. Implications of the results for human service providers are presented.     

Evolutionary politics? Union differences and political activities in the 1990s

Conclusion The political environment faced by U.S. unions has changed substantially over the past decade. The cost of election campaigns has increased dramatically and many interest groups have become actively involved in election financing. More importantly, the election of a Republican majority to Congress in 1994 caused a major change in the nature of unions' interactions with Washington legislators. Organized labor has faced a barrage of bills aimed at reducing the power of unions and minimizing their political involvement. Such efforts have also occurred across the country as conservative groups have attempted to qualify referenda that limit unions in some way. At a time when unions must organize new workers to survive as a viable force in society, these political challenges are especially serious matters.     

The Place and Relevancy of Practice with Couples in Graduate Social Work Education

Social workers often provide services and therapy for couples; however, little literature has been published that suggests models for teaching—from a social work perspective—marriage counseling or social work with couples. This article reports the results of a survey that examined how faculty in graduate schools of social work are teaching practice content in marriage counseling and their perceptions of its relevancy to social work practice. Findings indicated that some content on social work practice with couples is evident in most master of social work programs. Moreover, faculty perceived social work practice with couples as moderately relevant to all practice settings listed in the survey.     

Sleep hygiene practices and sleep duration in rotating-shift shiftworkers

Abstract

Alcohol, caffeine and tobacco intake, exercise, activities on going to bed, and sleep-enhancing measures were assessed in 72 rotating-shift shiftworkers to determine whether these variables differ following day shifts and night-shifts, and which are related to sleep duration. Only alcohol intake and exercise prior to sleep, and feeling drowsy when retiring, differed following the night-shift. Workers generally followed recommendations concerning alcohol intake, sleeping immediately on retiring, and exercising, but acted contrary to recommendations concerning caffeine and nicotine intake. The only behaviour clearly associated with poor sleep was smoking, which reduced sleep duration.
