A new mathematical approach for the estimation of the AUC and its variability under different experimental designs in preclinical studies

The aim of the present work was to develop a new mathematical method for estimating the area under the curve (AUC) and its variability that could be applied in different preclinical experimental designs and amenable to be implemented in standard calculation worksheets. In order to assess the usefulness of the new approach, different experimental scenarios were studied and the results were compared with those obtained with commonly used software: WinNonlin® and Phoenix WinNonlin®. The results do not show statistical differences among the AUC values obtained by both procedures, but the new method appears to be a better estimator of the AUC standard error, measured as the coverage of 95% confidence interval. In this way, the new proposed method demonstrates to be as useful as WinNonlin® software when it was applicable. Copyright © 2011 John Wiley & Sons, Ltd.     

Building family functioning scales into the study of at-home income generation

This article describes testing of scales designed to measure the ways family members interact in a personal subsystem. The scales are intended to complement data about the managerial subsystem of a family and are to be used in conjunction with a regional research project focused on home-based work. The article includes conceptual underpinnings, construction of measures, and results of factor analysis of the measures administered. Suggestions for use of a family functioning scale in the context of a household that has a member working at home are explored in the final section.This article reports results from the Cooperative Regional Research Project, NE-167, entitled, At-Home Income Generation: Impact on Management, Productivity and Stability in Rural and Urban Families, partially supported by Cooperative States Research Service, U.S. Department of Agriculture, and the Experiment Stations at the University of Hawaii, Iowa State University, Lincoln University (Missouri), Michigan State University, Cornell University (New York), The Ohio State University, The Pennsylvania State University, Utah State University, and the University of Vermont.Her research interests include measuring household production, at-home income generation and rural families. She received her Ph.D. in Family and Consumer Economics from the University of Missouri-Columbia.Her research is primarily in poverty and divorce and the economic well-being of women and children.

The utilization of child care by households engaged in home-based employment

A logit procedure is used to examine the factors associated with the likelihood of using child care services among a sample of households with both a home-based worker and a child designated as needing care. Being a single-parent, having high family income, and the presence of a two-year old child are positively associated with the likelihood of using child care. Being an older worker, having a child who is one year or less or children who are 11 to 12 years, and having a less professional occupation decreases the likelihood of using child care. Self-employment decreases the likelihood of usage; owning a business that hires employees or services increases the likelihood of usage. The major conclusion is that home-based work may be a coping strategy for some child care needs, but home-based working households often need and use child care.This article reports results from the Cooperative Regional Research Project, NE-167, entitled, At-Home Income Generation: Impact on Management, Productivity and Stability in Rural/Urban Families, partially supported by the Cooperative States Research Service, U.

DeFinettian Consensus

It is always possible to construct a real function , given random quantities X and Y with continuous distribution functions F and G, respectively, in such a way that (X) and (Y), also random quantities, have both the same distribution function, say H. This result of De Finetti introduces an alternative way to somehow describe the `opinion' of a group of experts about a continuous random quantity by the construction of Fields of coincidence of opinions (FCO). A Field of coincidence of opinions is a finite union of intervals where the opinions of the experts coincide with respect to that quantity of interest. We speculate on (dis)advantages of Fields of Opinion compared to usual `probability' measures of a group and on their relation with a continuous version of the well-known Allais' paradox.     

Mixture of Maximal Quasi Orders: a new Approach to Preference Modelling

Normative theories suggest that inconsistencies be pointed out to the Decision Maker who is thus given the chance to modify his/her judgments. In this paper, we suggest that the inconsistencies problem be transferred from the Decision Maker to the Analyst. With the Mixture of Maximal Quasi Orders, rather than pointing out incoherences for the Decision Maker to change, these inconsistencies may be used as new source of information to model his/her preferences.     

Practitioners' perceptions and decision‐making regarding child sexual exploitation – a qualitative vignette study

There has been intense controversy about the appropriate response to child sexual exploitation, with debates in the UK particularly hinging on the meaning of consent and coercion. For professionals with a duty to safeguard young people from child sexual exploitation, a key site of tension is how to avoid limiting young people's experience of agency without placing them at risk. Drawing on new qualitative research findings from a vignette study designed to trace professional perception and decision‐making, this paper argues that practitioners' perceptions regarding what counts as consent are refracted through conceptions of age and choice. However, many initial perceptions of agency and its links to age were modified through the interview process. This has implications for how supervision should operate. These topics raise issues of the need for practitioners to have nuanced conceptions of consent in the context of manipulation.     

University environment and entrepreneurial intention: the mediating role of the components of the theory of planned behaviour / El entorno universitario y la intención emprendedora: el papel mediador de los componentes de la teoría de la acción planificada

Entrepreneurship contributes to job creation and economic development. Thus, it is important to promote entrepreneurial initiatives; universities play a key role in this regard. The psychosocial perspective can contribute a great deal to studying the antecedents that lead a person to become an entrepreneur, with the theory of planned behaviour (TPB) being the theoretical framework used the most to predict entrepreneurial intention. Based on the data collected in Spain as part of the international GUESSS project (Global University Entrepreneurial Spirit Students’ Survey) with a sample of 9,753 students, the influence of the university environment, the entrepreneurial environment and the perceived risk of entrepreneurship on entrepreneurial intention are analysed, both directly and as mediated by the three components of the TPB (attitudes towards entrepreneurship, subjective norms and entrepreneurial self-efficacy). The results show that the university environment is the antecedent with the greatest effect on entrepreneurial intention; therefore, it is recommended that entrepreneurship be promoted through initiatives and educational programmes in the university environment.     

Necessary Disruptions: A Discussion of Daniel Butler’s “Racialized Bodies and the Violence of the Setting”

This discussion of Daniel Butler’s article “Racialized Bodies and the Violence of the Setting” takes up the importance of the concept of place, largely through the lens of Frantz Fanon. It argues that being is best understood as being placed, emphasizing the necessity of material and historical setting for any ontological formation. Very tentatively, it advances a fragile hope that Whiteness is currently being placed in a way that can no longer be regarded as something universalized and invisible.

May the force be with you: Looking for resources that build team resilience

The aim of this study is to analyze team resilience as a collective psychosocial construct in the framework of the conservation of resources theory. Specifically, the authors hypothesize that (a) team-level resources and (b) organizational-level healthy practices would be positively related to team resilience. Multilevel regression modeling was conducted, using data from 1,167 employees nested in 194 work teams (team level) from 38 organizations (organizational level). Results confirmed the hypotheses having team-level resources and organizational-level healthy practices significant relationships with team resilience. This study provides evidence that team and organizational resources have a strong relationship with team resilience. Practitioners and managers must take these results into account for planning how to manage their resources within the organization. This article found what resources are required (at the team and the organizational level) to help work-team resilience.
