Content validation on the Work Performance Rating Scale for sheltered workshop workers

The purpose of this study was to revise the content of the Work Performance Rating Scale (WPRS) as a valid assessment tool for sheltered workshop workers. A focus group of 11 sheltered workshop workers was recruited to collect their opinions about the relevance of the WPRS from the service users' perspectives. A panel of 23 frontline practitioners who had experience in using various work assessment instruments provided at their work setting was recruited to review the content of the WPRS. A 14-item amended version of the WPRS with five new items added was proposed based on the opinions of service users, frontline practitioners, and the concept of the Minnesota Theory of Work Adjustment (MTWA). An expert panel of 12 professionals at the senior level from various vocational rehabilitation settings was recruited to comment on the content validity of the 14-item amended version of the WPRS. The expert panel agreed that the amended version of the WPRS was related to the concept of job satisfactoriness which could be used to assess the work performance of sheltered workshop workers. Thus, the use of the MTWA for improving the content validity of the WPRS to assess the employability of sheltered workshop workers was supported by the findings of the study.     

Carnal Connections: On Embodiment,Apprenticeship, and Membership

This article responds to the special issue of Qualitative Sociology devoted to the author's book, Body and Soul: Notebooks of an Apprentice Boxer (vol. 28, no. 3, summer 2005). Four themes are tackled: the positioning of the inquirer and the question of social acceptance and membership; the dynamics of embodiment(s) and the variable role of race as a structural, interactional, and dispositional property; the functioning of the boxing gym as miniature civilizing and masculinizing machine; apprenticeship as a mode of knowledge transmissioin and technique for social inquiry, the scope of carnal sociology, and the textual work needed to convey the full-color texture and allure of the social world. This leads to clarifying the conceptual, empirical, and rhetorical makeup of Body and Soul in relation to its triple intent: to elucidate the workings of a sociocultural competency residing in prediscursive capacities; to deploy and develop the concept of habitus as operant philosophy of action and methodological guide; and to offer a brief for a sociology not of the body (as social product) but from the body (as social spring and vector of knowledge), exemplifying a way of doing and writing ethnography that takes full epistemic advantage of the visceral nature of social life. Response to the special issue of Qualitative Sociology on Body and Soul, vol. 28, no. 2, Summer 2005.     

Epidemiologic network inference

Statistics and Computing - In many epidemiologic models, a disease is assumed to spread along a contact network. We aim to infer this network, in addition to the epidemiologic model parameters,...     

Testing for residual correlation of any order in the autoregressive process

We are interested in the implications of a linearly autocorrelated driven noise on the asymptotic behavior of the usual least-squares estimator in a stable autoregressive process. We show that the least-squares estimator is not consistent and we suggest a sharp analysis of its almost sure limiting value as well as its asymptotic normality. We also establish the almost sure convergence and the asymptotic normality of the estimated serial correlation parameter of the driven noise. Then, we derive a statistical procedure enabling to test for correlation of any order in the residuals of an autoregressive modelling, giving clearly better results than the commonly used portmanteau tests of Ljung–Box and Box–Pierce, and appearing to outperform the Breusch–Godfrey procedure on small-sized samples.     

Asymptotic normality of a robust estimator of the regression function for functional time series data

We propose a family of robust nonparametric estimators for a regression function based on the kernel method. We establish the asymptotic normality of the estimator under the concentration property on small balls probability measure of the functional explanatory variable when the observations exhibit some kind of dependence. This approach can be applied in time series analysis to make prediction and build confidence bands. We illustrate our methodology on the US electricity consumption data.     

De Genève à San José: les normes de l'OIT et le système interaméricain de protection des droits humains

Les auteurs démontrent comment les instances interaméricaines de protection des droits humains ont utilisé les normes de l'OIT. Après avoir posé les limites de cet usage, ils l'illustrent par des exemples relatifs au droit à la liberté d'association et aux droits des peuples autochtones. Ils analysent aussi comment ces normes ont influencé la jurisprudence interaméricaine récente relativement à certains droits économiques, sociaux et culturels. Ils affirment que cette méthode de référencement croisé est souhaitable et utile: elle permet aux instances interaméricaines de fonder leur argumentaire sur l'interprétation d'autorités spécialisées, tout en renforçant la crédibilité et la légitimité normative de leurs décisions, qui gagnent en universalité.     

Triarchic Model of Grit Dimensions as Predictors of Career Outcomes

Recent studies have emphasized the importance of applying positive psychological theories in the context of career development (Hull et al., 2020; Vela et al., 2015, 2019). However, limited research has been carried out on how specific positive personality traits might contribute to optimal career functioning. We addressed this gap by exploring the link of a triarchic model of grit dimensions (i.e., perseverance of effort, consistency of interests, and adaptability to situations) to career maturity, career decision-making self-efficacy, and career goal setting among Hong Kong Chinese secondary school students. Perseverance of effort positively predicted career goal setting and career decision-making self-efficacy. Consistency positively predicted career goal setting and career maturity. Adaptability to situations positively predicted career maturity, career decision-making self-efficacy, and career goal setting. Results point to the importance of designing school-based grit interventions to facilitate optimal career-related functioning.     

A likelihood ratio test of a homoscedastic normal mixture against a heteroscedastic normal mixture

It is generally assumed that the likelihood ratio statistic for testing the null hypothesis that data arise from a homoscedastic normal mixture distribution versus the alternative hypothesis that data arise from a heteroscedastic normal mixture distribution has an asymptotic χ ² reference distribution with degrees of freedom equal to the difference in the number of parameters being estimated under the alternative and null models under some regularity conditions. Simulations show that the χ ² reference distribution will give a reasonable approximation for the likelihood ratio test only when the sample size is 2000 or more and the mixture components are well separated when the restrictions suggested by Hathaway (Ann. Stat. 13:795–800, 1985) are imposed on the component variances to ensure that the likelihood is bounded under the alternative distribution. For small and medium sample sizes, parametric bootstrap tests appear to work well for determining whether data arise from a normal mixture with equal variances or a normal mixture with unequal variances.     

Efficiency evaluations with context-dependent and measure-specific data envelopment approaches: An application in a World Bank supported project

We evaluate the efficiency of decision making units (DMUs) in a World Bank supported Social Risk Mitigation Project (SRMP) in Turkey through context-dependent and measure-specific data envelopment analysis (DEA) approaches. The results suggest that the efficiency evaluations with context-dependent and measure-specific DEA play various roles in an organization such as setting attainable targets to DMUs, setting long and short term targets to DMUs separately, grouping of DMUs, and improving internal competition between DMUs. Four main contributions of this study can be summarized as follows. Firstly, the study shows the applicability of context-dependent and measure-specific DEA methodologies in a World Bank supported large scale project to increase the effectiveness of the project. Secondly, it outlines some important managerial conclusions of context-dependent DEA clustering approach. Moreover, we propose an alternative approach for attractiveness scores computations in case of exogenous group formations. Finally, the study proposes and applies measure-specific version of context-dependent DEA approach.
