Retroactive phantasies: discourse,discipline, and the production of race

The present inquiry considers how the practice and notion of race can be figured as a type of discipline that functions to achieve the subjection of the individual – to form the individual as a racial subject. Focusing on the constructions of blackness and whiteness within US racial rhetoric, and engaging the work of Michel Foucault and Judith Butler, I propose that racial identity is a retroactive phantasy that is always conditional on the subject enacting the very power that marks them: the formation and maintenance of subjectivity is premised on the individual being formed and forming themselves in relation to a normalized identity site and is, thus, always an action. Precisely due to this necessity to act, and to the incoherence of power, innovative acts of anti-discipline re-negotiate the ways in which racial subjectivity is lived and realized.     

Estimating and Validating Nonlinear Regression Metamodels in Simulation

Frequently, the main objective of statistically designed simulation experiments is to estimate and validate regression metamodels, where the regressors are functions of the design variables and the dependent variable is the system response. In this article, a weighted least squares procedure for estimating the unknown parameters of a nonlinear regression metamodel is formulated and evaluated. Since the validity of a fitted regression model must be tested, a method for validating nonlinear regression simulation metamodels is presented. This method is a generalization of the cross-validation test proposed by Kleijnen (1983 Kleijnen , J. P. C. ( 1983 ). Cross-validation using the t statistic . European Journal of Operational Research 13 : 133 – 141 .[Crossref] , [Google Scholar]) in the context of linear regression metamodels. One drawback of the cross-validation strategy is the need to perform a large number of nonlinear regressions, if the number of experimental points is large. In this article, cross-validation is implemented using only one nonlinear regression. The proposed statistical analysis allows us to obtain Scheffé-type simultaneous confidence intervals for linear combinations of the metamodel's unknown parameters. Using the well-known M/M/1 example, a metamodel is built and validated with the aid of the proposed procedure.     

Reliability and Validity of the European Portuguese Version of the Social Touch Questionnaire

Social touch is essential for physical and emotional well-being. However, different meanings can be attributed to physical contact during social interactions and may generate bonding or avoidant behaviors. This personal and unique experience is not usually taken into account in health and social care services. The aim of this study is to produce a valid and reliable European Portuguese version of the Social Touch Questionnaire (STQ, Wilhelm et al. in Biol Psychol 58:181–202, 2001. doi: 10.1016/S0301-0511(01)00113-2). The STQ is a self-report questionnaire for adolescents and adults measuring behaviors and attitudes towards social touch. The original version was translated into European Portuguese using a forward-back translation process and its feasibility was examined. To evaluate the psychometric properties, a total of 242 Portuguese university students participated in the study (21.3 ± 3.8 years). The STQ was considered feasible, showed adequate internal consistency (Cronbach’s α = .734), and the test–retest correlation with the STQ items demonstrated a high concordance between the tests over a two-week interval (ICC = .990; n = 50). Validity tests were performed, comparing the total score of the STQ with that of the anxiety and avoidance subscales of the Social Interaction and Performance Anxiety and Avoidance Scale (SIPAAS). A very significant conceptual convergence was confirmed between the STQ and with the SIPAAS-Anxiety (r = .64; p < .0001) and with the SIPAAS-Avoidance (r = .59; p < .0001). The exploratory factor analysis, with Promax rotation, revealed 3 factors: dislike of physical touch, liking of familiar physical touch and liking of public physical touch (Cronbach’s alphas ranged from .68 to .75). Psychometric properties confirmed the adaptation of the STQ to the Portuguese culture. It is a reliable and valid self-report questionnaire and it appears to be a useful tool to assess behaviors and attitudes towards social touch.

Impact of Uncertainty Parameter Distribution on Robust Decision Making Outcomes for Climate Change Adaptation under Deep Uncertainty

Deep uncertainty in future climatic and economic conditions complicates developing infrastructure designed to last several generations, such as water reservoirs. In response, analysts have developed multiple robust decision frameworks to help identify investments and policies that can withstand a wide range of future states. Although these frameworks are adept at supporting decisions where uncertainty cannot be represented probabilistically, analysts necessarily choose probabilistic bounds and distributions for uncertain variables to support exploratory modeling. The implications of these assumptions on the analytical outcomes of robust decision frameworks are rarely evaluated, and little guidance exists in terms of how to select uncertain variable distributions. Here, we evaluate the impact of these choices by following the robust decision-making procedure, using four different assumptions about the probabilistic distribution of exogenous uncertainties in future climatic and economic states. We take a water reservoir system in Ethiopia as our case study, and sample climatic parameters from uniform, normal, extended uniform, and extended normal distributions; we similarly sample two economic parameters. We compute regret and satisficing robustness decision criteria for two performance measures, agricultural water demand coverage and net present value, and perform scenario discovery on the most robust reservoir alternative. We find lower robustness scores resulting from extended parameter distributions and demonstrate that parameter distributions can impact vulnerabilities identified through scenario discovery. Our results suggest that exploratory modeling within robust decision frameworks should sample from extended, uniform parameters distributions.     

Multivariate models for correlated count data

In this study, we deal with the problem of overdispersion beyond extra zeros for a collection of counts that can be correlated. Poisson, negative binomial, zero-inflated Poisson and zero-inflated negative binomial distributions have been considered. First, we propose a multivariate count model in which all counts follow the same distribution and are correlated. Then we extend this model in a sense that correlated counts may follow different distributions. To accommodate correlation among counts, we have considered correlated random effects for each individual in the mean structure, thus inducing dependency among common observations to an individual. The method is applied to real data to investigate variation in food resources use in a species of marsupial in a locality of the Brazilian Cerrado biome.     

Problem Gambling and its Impact on Families: A Literature Review

This paper offers an overview of the existing literature concerning problem gambling and families and identifies gaps in current research knowledge on this topic. Relevant theoretical perspectives are outlined and the role of familial factors in the development of problem gambling is discussed. This is followed by a focused review of the effects of problem gambling on family members, specifically the spouse, children and parents. Available treatments and therapies for family members are also reviewed. The paper concludes by identifying the limitations of existing knowledge and some directions for future research on this topic.     

Participation in Income-Generating Activities and Help-Seeking for IPV in Bangladesh – Results from a National Survey of Women

Abstract

The present study examined whether there was an association between microfinance participation (i.e. microentrepreneurship) and help-seeking social networks and employment and help-seeking social networks of women who experienced intimate partner violence (IPV) in Bangladesh. The study is a secondary analysis of a subsample of 805 women (24.1% of the representative sample) who experienced IPV from the 2007 Bangladesh Demographic and Health Survey (BDHS) between the ages of 16 and 49?years. Results indicate that among the subsample of 805 respondents, 29.3% sought help for IPV. Multivariate logistic regression revealed that women who were employed all year round were significantly more likely and microfinance participants were marginally more to seek help for IPV than women who were not engaged in income-generating activities. Implications are discussed.     

The Day-to-Day Reality of Delivering Shelter Services to Women Exposed to Intimate Partner Violence in the Context of System and Policy Demands

ABSTRACT

Intimate partner violence (IPV) is the most common form of gender-based violence affecting Canadian women. Women often seek help from shelters to deal with IPV and its consequences. These shelters function within a broader context that shapes how services are delivered. This study was undertaken to better understand how structural factors including policies shape shelter service delivery and reveal systemic and structural complexities that influence those services and women's ability to rebuild their lives. This feminist qualitative study combined in-depth interviews and focus groups with 37 staff and 4 executive directors from 4 shelters in Ontario, Canada, and included critical discourse analysis of salient policy texts. The findings illuminate the complexity of the structural challenges faced by abused women and the shelters that support them. Systemic impediments were shown to determine how shelters support abused women, the obstacles women face moving forward, and the extent and availability of their options. Future research should include policy evaluation of policy written and enacted, cost analysis examining the actual costs of delivering shelter services and supporting women after leaving, examination of potential alternatives to the identified structural challenges, and investigation of system coordination of services and support for abused women.     

‘A drop in the bucket‘: Collective efficacy perceptions and environmental behaviour

Environmental degradation is a complex problem, many aspects of which may not be solved unless collective effort is undertaken. Collective Efficacy theory provides a useful framework to investigate how people view their ability and the effectiveness of their actions to solve environmental problems, which has been largely overlooked until now. Six focus groups were conducted to explore efficacy beliefs expressed by environmental Activists and Non‐Activists in Perth, Western Australia, relating to waste management. All participants (n=38) expressed pessimistic views about the abilities of others to perform pro‐environmental behaviours. However, Activists were positive that a collective effort would be effective (‘many drops will fill up the bucket’) while Non‐Activists felt strongly that the problem would still exist even if everyone performed waste‐minimising behaviours (‘it's just a drop in the bucket’). Behaviour change interventions might be more effective if they focus on convincing people that collective effort will be effective in solving environmental problems.
