Institutional Ethnography and Experience as Data

Experience, as concept, is contested among feminists as to its epistemological status, thus its usefulness in knowledge claims. Institutional ethnography (Smith 1987) is a feminist methodology that nonetheless relies fundamentally on people's experience. Not as Truth, nor the object of inquiry, but as thepoint d'appui for sociological inquiry. This article offers a demonstration of institutional enthnography using observational and interview data that show experience as methodologically central to a trustworthy analysis. A moment in the work lives of nursing assistants in a long-term care setting is captured by a participant observer. The analysis produces two lines of argument. One is methodological; it is argued that nursing assistants' experiences are an entry into the social relations of the setting that, when mapped and disclosed, make those experiences understandable in terms of the ruling arrangements permeating both the organization and their own experiences. The other argument is substantive; the inquiry uncovers how a quality improvement' strategy in a long term care hospital in Canada is reorganizing caregivers' values and practices toward a market orientation in which care appears to be compromised. Use of experience as data in this approach holds the analysis accountable to everyday/everynight actualities in a lived world.     

Attenuating Initial Beliefs: Increasing the Acceptance of Anthropogenic Climate Change Information by Reflecting on Values

Anthropogenic climate change information tends to be interpreted against the backdrop of initial environmental beliefs, which can lead to some people being resistant toward the information. In this article (N = 88), we examined whether self‐affirmation via reflection on personally important values could attenuate the impact of initial beliefs on the acceptance of anthropogenic climate change evidence. Our findings showed that initial beliefs about the human impact on ecological stability influenced the acceptance of information only among nonaffirmed participants. Self‐affirmed participants who were initially resistant toward the information showed stronger beliefs in the existence of climate change risks and greater acknowledgment that individual efficacy has a role to play in reducing climate change risks than did their nonaffirmed counterparts.     

Multilevel maximum likelihood estimation with application to covariance matrices

The asymptotic variance of the maximum likelihood estimate is proved to decrease when the maximization is restricted to a subspace that contains the true parameter value. Maximum likelihood estimation allows a systematic fitting of covariance models to the sample, which is important in data assimilation. The hierarchical maximum likelihood approach is applied to the spectral diagonal covariance model with different parameterizations of eigenvalue decay, and to the sparse inverse covariance model with specified parameter values on different sets of nonzero entries. It is shown computationally that using smaller sets of parameters can decrease the sampling noise in high dimension substantially.     

Social Cognitive Factors,Support, and Engagement: Early Adolescents’ Math Interests as Precursors to Choice of Career

The authors examined the central hypothesis that students’ early perceptions of support and sense of engagement in math classes and math activities strongly influence the broadening or narrowing of their math interest. The focus was on the first wave of qualitative data collected from 5th‐, 7th‐, and 9th‐grade students during the 2007–2008 academic year as part of a longitudinal study. Findings indicate the importance of using group work and extrinsic motivation in middle school math classes to broaden interest; peer classroom behavior was often a detractor of math interest.     

Adult Sexual Outcomes of Child Sexual Abuse Vary According to Relationship Status

This study tested a moderation model in which the association between child sexual abuse severity and negative sexual outcomes (i.e., sexual avoidance and compulsivity) differed as a function of relationships status (i.e., single, cohabiting, and married individuals). A sample of 1,033 adults completed self‐report questionnaires online, and 21.5% reported childhood sexual abuse. Path analyses indicated that child sexual abuse severity was associated with higher sexual compulsivity in single individuals, both higher sexual avoidance and compulsivity in cohabiting individuals, and higher sexual avoidance in married individuals. The moderation model was invariant across men and women. These results suggest that the time course of negative sexual outcomes associated with child sexual abuse may follow distinct patterns of expression according to relationship status.     

A grounded theory of living a life with a physical disability in Taiwan

This study explores the experiences of disability for a number of Taiwanese adults with a physical disability. Using a grounded theory approach, their experiences of living a life with a physical disability were gained through in-depth interviews. The resulting grounded theory ‘it is more than just the impaired body’ presents the dynamic interactions between the participants and the context in which they were living their lives and how they managed their lives within that context. With its inclusion of the cultural dimension, a holistic way of understanding the daily lives of those who experience physical disability in Taiwan is provided.     

Social (Dis)Approval and Collective Action Participation: Re‐evaluating the Positive Linearity Thesis

Survey‐based studies on collective action generally assume that social approval of participation in collective action has a positive and linear effect on actual participation. However, this assumption has not yet been subjected to a genuine empirical evaluation. This article investigates the positive linearity thesis, using survey data on participation and non‐participation in a street demonstration in The Hague in 2011. Statistical analyses provide evidence in support of a curvilinear relation between social approval and participation—an increased rate of participation in case of both approval and disapproval by peers. We discuss two processes underlying the observed relation: one pertaining to rebelliousness and the other regarding political awareness. The article generally illustrates the need for further empirical research on social influence and participation in collective action.     

Bridge Leadership: Gendered Consumerism and Black Women’s Political Power within Early 20th Century “Don’t Buy” Campaigns

This research surveys the literature around black consumerism and social movements, exploring the “Don’t Buy Where You Can’t Work” (DBWYCW) campaigns of the 1920s-1940s. The author examines the integral roles women played (as organizers, agitators, and beneficiaries) in various economic boycotts within the context of Belinda Robnett’s theory of bridge leadership, with a particular focus on consumerism as a major vehicle through which African-American women engaged in movement work during the DBWYCW campaigns. This article challenges the erasure of women’s leadership by reframing “Don’t Buy” as a women’s movement. Applying Robnett’s bridge leadership theory to different eras, regions, and movements, we see how the Great Depression combined with activism in the gendered sphere of consumerism and facilitated the activism of black women. This paper also expands Robnett’s conceptualization of professional and indigenous bridge leaders by identifying urban working class women within the “Don’t Buy” movement who fit these leadership categories.     

Impact of physical activity and sedentary behaviour on fall risks in older people: a systematic review and meta-analysis of observational studies

The objective of this work was to summarise and evaluate the evidence showing that physical activity is a protector factor as regards falls in older people. Relevant studies were identified through a systematic search in the MEDLINE and Cochrane Library, under the keywords of accidental fall/numerical data and risk factors, and with the bibliographies of retrieved papers. The combined odds ratio (OR) [95% confidence interval] for physical activity was 0.75 [0.64, 0.88] with moderate heterogeneity (I ²?=?33%). For fall injury, it was 0.59 [0.47, 0.74] and, for falls in general, it rose to 0.94 [0.76, 1.17] with nil heterogeneity. The combined OR for sedentary factors was 1.14 [1.10, 1.82] with moderate heterogeneity (I ²?=?36%). Regular physical activity in daily life yields significant reduction in falls in older people, especially falls with injuries.
