Estimating the Relative Density of Snapper in and around a Marine Reserve Using a Log-Linear Mixed-Effects Model

Angling from small recreational fishing boats was used as a sampling method to quantify the relative density of snapper ( Pagrus auratus ) in six areas within the Cape Rodney-Okakari Point Marine Reserve (New Zealand) and four areas adjacent to the reserve. Penalized quasi-likelihood was used to fit a log-linear mixed-effects model having area and date as fixed effects and boat as a random effect. Simulation and first-order bias correction formulae were employed to assess the validity of the estimates of the area effects. The bias correction is known to be unsuitable for general use because it typically over-estimatesbias, and this was observed here. However, it was qualitatively useful for indicating the direction of bias and for indicating when estimators were approximately unbiased. The parameter of primary interest was the ratio of snapper density in the marine reserve versus snapper density outside the reserve, and the estimator of this parameter was first-order asymptotically unbiased. This ratio of snapper densities was estimated to be 11 (±3).     

Interviewing vulnerable old people: ethical and methodological implications of imagining our subjects

It is sometimes argued that interview research with vulnerable social groups, such as frail, lonely, older people, has distinctive ethical and methodological requirements. The conventional one-off, professional interview is seen to be both inadequate as a method of data collection and inimical to the interest of research subjects. While ideologically persuasive, such a view is not derived from systematic analysis of actual interviews. In this article, I describe a research project on social isolation in which the conceptualization of elderly interviewees as "vulnerable subjects" had a number of critical but intended impacts on the course and outcomes of the research. I offer an empirically grounded analysis of the interview situation that suggests an alternative reading of the relationship between social representation of aging persons and the methods we use to study them.     

Gambling Responsibly: Who Does It and To What End?

Numerous responsible gambling (RG) strategies are promoted to assist consumers to “gamble responsibly”. However, consumer adoption of RG strategies, how this varies by gambler risk group, and whether usage is associated with non-problematic gambling are largely unknown. This study aimed to (1) determine how use of RG-related strategies differs amongst regular gamblers by gambler risk group; and (2) identify RG-related strategies whose usage predicts non-problem/low risk gambling. Regular Australian gamblers on high-risk products (N = 860), recruited through gambling venues and an online wagering operator, were surveyed about their use of RG strategies promoted on the website of their jurisdiction’s main RG agency. Knowledge of RG strategies was reasonably high amongst all gambler risk groups, but lower-risk groups were more likely to use RG strategies. A logistic regression correctly predicted 82.1 % of lower-risk gamblers and 77.2 % of higher-risk gamblers. Predictors of lower-risk gambling included: greater confidence in their understanding of RG; endorsement of lower gambling expenditure and frequency limits; fewer erroneous gambling beliefs; being less likely to gamble to win money, challenge their skills/beat the odds, or forget about worries and stresses; and being more likely to gamble for pleasure/entertainment. Lower-risk gamblers were more likely to set a money limit in advance of gambling and to balance their gambling with other activities. These findings contribute to understanding which strategies are favoured by different risk groups, and which are associated with safer levels of gambling. They can guide consumer information aimed at enhancing RG consumption and future research on RG consumption.     

Diagnostics for the bootstrap and fast double bootstrap

ABSTRACT

The bootstrap is typically less reliable in the context of time-series models with serial correlation of unknown form than when regularity conditions for the conventional IID bootstrap apply. It is, therefore, useful to have diagnostic techniques capable of evaluating bootstrap performance in specific cases. Those suggested in this paper are closely related to the fast double bootstrap (FDB) and are not computationally intensive. They can also be used to gauge the performance of the FDB itself. Examples of bootstrapping time series are presented, which illustrate the diagnostic procedures, and show how the results can cast light on bootstrap performance.     

‘Environment’ Submissions in the UK's Research Excellence Framework 2014

There has been much debate about university research assessment exercises. In the UK, a major element of the 2014 Research Excellence Framework (REF2014) has been the research environment. Here we analyse 98 REF2014 ‘environment’ submissions in Business and Management Studies. We explore whether there are distinctive language‐related differences between submissions of high and low ranked universities and conclude that submission writers have a strong incentive to exaggerate strengths and conceal problems. In addition, innate biases such as the ‘halo’ and ‘velcro’ effects may distract the attention of assessors from a submission's strengths and weaknesses, since they are likely to influence their pre‐existing impressions. We propose several changes to improve how environment is evaluated. We also argue that the research environment would be more likely to be enhanced if the number of outputs submitted in future was an average of two and a maximum of four per academic, rather than the maximum of five currently being considered.     

Geographies in the American DeafWorld as institutional constructions of the deaf body in space: the sensescape model

Space is a site where culture and body meet. It is a physical text of cultural constructions of the body that articulate personal, social and material functions and arrangements. The American DeafWorld consists of spaces where deaf and hard of hearing people are found. The geographies in the DeafWorld are the sites where different institutions create and imprint their ideologies, practices and properties pertaining to their sensory notions of the deaf body onto brick-and-mortar spaces in the DeafWorld. Sensescape is proffered as a theoretical model to describe DeafWorld institutional geographies.     

Ambivalent Homoprejudice towards Gay Men: Theory Development and Validation

ABSTRACT

Myriad social groups are targets of hostile and benevolent (i.e., ambivalent) prejudice. However, prejudice toward gay men is typically conceptualized as hostile, despite the prevalence of benevolence toward gay men in popular media. This article aims to compare gay men with other targets of ambivalent prejudice (i.e., women and elderly people) and draw on the stereotype content and microaggressions literatures in order to develop a theory of ambivalent homoprejudice. The resultant framework, comprising repellent, adversarial, romanticized, and paternalistic homoprejudice was investigated using seven focus groups of heterosexuals and gay men (N = 22), and the findings were consistent with stereotype content theory. Directions for future research into the deleterious effects of ambivalent homoprejudice and possible empowering interventions are discussed.

Socializing the Silent Treatment: Parent and Adult Child Communicated Displeasure,Identification, and Satisfaction

Responding to evidence that the silent treatment is a relational-harming means of communicating disappointment in interpersonal relationships, this study focused on the silent treatment’s role and transmission within the family. Adult children’s (N = 182) self-reported silent-treatment behaviors were negatively related to their own self-esteem, and the satisfaction they reported for their primary parent was negatively related to that parent’s silent treatment. The parent’s admitting displeasure, however, was positively related to this satisfaction and positively associated with the child’s feelings of control. Revealed sex differences were minor and outside of gendered expectations for communicating disappointment. In testing parent socialization of the silent treatment, parent silent-treatment use was positively associated with the adult child’s silent-treatment use, with no demonstrated mediation by parent identification.     

The Practicalities and Perils of Ambulatory Assessment's Promise: Introduction to a Special Section

Ambulatory assessment (AA) offers one of the most exciting approaches for opening the dynamic “black box” of adolescents’ daily lives. In this introduction, we spotlight AA's surprisingly restricted market share within adolescent scholarship. We describe thorny challenges these intense methods can pose when conducting adolescent research “in situ” and underscore that capturing quality AA data means placing adolescents’ developmental stage at the forefront. The novel research reported in this special section speaks to these challenges and underscores the promise of AA for conducting developmentally salient science. The nine articles included in the section span multiple disciplines (Sociology, Psychology, Public Health) and reflect diverse viewpoints, approaches, and theories. All provide multiple novel best‐practice strategies for conducting AA scholarship with adolescents.
