How volunteerism inhibits mobilization: a case study of shelter animal advocates

This paper presents an analysis of how volunteerism can neutralize impulses for mobilization. An ethnographic case study of shelter animal advocates, or individuals promoting shelter reform to ensure that companion animals impounded at animal shelters receive proper medical and behavioral care and are given opportunity for adoption, illuminates a specific set of mechanisms that explain why they have not engaged in collective action such as protest. The findings speak to the complex debate about the relationship between volunteerism, political engagement, and social change by identifying five processes that undercut shelter animal advocates’ capacity to act collectively in protest of how the shelter is run: (1) periods of grievance interruption; (2) exposure to the target’s institutional narratives; (3) relational ties to the target; (4) conflict avoidance; and (5) maintenance of identity as volunteers.     

A Sample Size Formula for a Non-Central t Test

An elementary method of proof of the mode, median, and mean inequality is given for skewed, unimodal distributions of continuous random variables. A proof of the inequality for the gamma, F, and beta random variables is sketched.     

Power Mapping: Enhancing Sociological Knowledge by Developing Generalizable Analytical Public Tools

In this article, I argue for and illustrate ‘power mapping’ as a concrete research approach that can benefit specific publics while enhancing professional sociological knowledge and theory. I present power mapping as an example of a more broad approach to public sociology which seeks to harness sociological theory and knowledge in order to create generalizable analytical tools that social movements, policy makers, concerned citizens, voluntary associations, and community organizations can use to develop their own strategic assessments of the sociological contexts in which they act. One of the ironies of the current discussion of public sociology is that it has been conducted in an abstract, hyper-theoretical discourse which is precisely one of the factors that has disconnected so much sociology from general publics. In this article, I instead turn towards presenting a specific concrete research strategy which could engender mutually beneficial research collaboration and dialogue between sociologists and specific publics.     

Disability and democracy in Cambodia: an integrative approach to community building and civic engagement

The political framework through which the various communities of disabled persons in Cambodia advocate for and claim their rights is complex and confusing. Both governmental and non‐governmental actors engage this political framework through the mobilization of persons from the various disabled communities, competing in the civic sphere through issue‐oriented advocacy in ways that seek to influence the process of democratic governance. While the status of disabled rights in Cambodia is still comparatively weak, it is argued here that this civic engagement has allowed disabled communities to find common cause with non‐disabled persons and groups in the project of deepening the roots of democracy in Cambodia. This article discusses the demographic composition of disability, the framework of political action that addresses disability issues and the practice of civic engagement and activism by disabled and non‐disabled communities in Cambodia.     

Perceptions and expectations of price changes and inflation: A review and conceptual framework

Drawing on relevant literature from a diverse range of academic disciplines we present a conceptual framework intended to further our understanding of perceptions and expectations of price changes and inflation. Based on this framework, we provide a detailed review of the literature and an analysis of open issues in current research. The review is primarily concerned with individuals’ perceptions and expectations of price changes and inflation, which can influence individuals’ economic behaviour (e.g. spending and saving decisions). The main insight from the review is that while consumers may have a limited ability to store and recall specific prices, and even succumb to a number of biases in the way in which they form perceptions and expectations of global price changes, they do seem to have some feel for, and ability to judge and forecast, inflation. How they achieve this, however, is still an open question, although plausible explanations have been proposed. While much important research has been undertaken and significant progress made in our understanding of the psychology of inflation, there remain many unanswered questions and interesting avenues for future research, which are discussed in the final part of the paper.     

The digital divide in Sydney

In Australia, there has been limited research into the issue of the digital divide. Even less attention has been given to the social and spatial characteristics of this phenomenon, particularly within metropolitan areas. This paper attempts to fill this gap by examining the social and spatial characteristics of computer and Internet use in Sydney. The findings suggest that those individuals who are socially and economically disadvantaged have lower rates of computer and Internet use, and that these individuals also risk exacerbating their disadvantage status if these demand-side barriers are not addressed. If we are to address disparities in computer and Internet use in Australia we need to consider more fully the social and spatial nature of such disparities that prevent individuals from accessing such technologies in an increasingly 'wired' world.     

Lessons from Drosophila models of DJ-1 deficiency

Mutations in the DJ-1 gene are associated with rare forms of autosomal recessive early-onset Parkinson's disease (PD). Although the precise physiological function of DJ-1 remains obscure, accumulating evidence suggests that DJ-1 may normally function as a redox-sensitive molecular chaperone that can protect against the deleterious effects of oxidative stress, particularly in mitochondria. Recent studies in the fruit fly, Drosophila melanogaster, have shed further light on the biological role of DJ-1. DJ-1-deficient Drosophila models exhibit distinct phenotypes but collectively highlight a prominent neuroprotective role for DJ-1 against oxidative insult. However, Drosophila lacking DJ-1 do not consistently produce a useful PD-like phenotype (that is, they generally fail to exhibit degeneration of neurons that contain the neurotransmitter dopamine), which may reflect putative compensatory neuroprotective mechanisms. DJ-1-deficient fly models further highlight the utility of Drosophila as an important tool for elucidating protein function and for modeling neurodegenerative disease.     

Normal theory sample size formulas for some nonnormal distributions

Sample size procedures of T- and F-tests for some nonnormal distributions are discussed. An adaptation to the Kruskal-Wallis and Friedman tests is mentioned.
