Absolute vs Relative Performance Rating Formats: Implications for fairness and organizational justice

The choice of performance rating format may influence employees' fairness perceptions. Participants in two studies, one consisting of 208 participants and the other of 393 participants, evaluated the fairness of common relative and absolute rating formats. The participants in the second study also evaluated the fairness of two rating formats, one absolute and one relative, presented in organizational contexts of varying procedural and distributive justice. Results indicate that not only are absolute formats perceived as more fair than relative formats, but differences in fairness perceptions also occur among relative and absolute formats. Furthermore, it appears that rating format influences procedural justice, especially when outcomes are perceived as fair. Implications for organizations' appraisal practices are discussed.     

The Heteroscedastic Graded Response Model with a Skewed Latent Trait: Testing Statistical and Substantive Hypotheses Related to Skewed Item Category Functions

The Graded Response Model (GRM; Samejima, Estimation of ability using a response pattern of graded scores, Psychometric Monograph No.?17, Richmond, VA: The Psychometric Society, 1969) can be derived by assuming a linear regression of a continuous variable, Z, on the trait, ??, to underlie the ordinal item scores (Takane & de Leeuw in Psychometrika, 52:393?C408, 1987). Traditionally, a normal distribution is specified for Z implying homoscedastic error variances and a normally distributed ??. In this paper, we present the Heteroscedastic GRM with Skewed Latent Trait, which extends the traditional GRM by incorporation of heteroscedastic error variances and a skew-normal latent trait. An appealing property of the extended GRM is that it includes the traditional GRM as a special case. This enables specific tests on the normality assumption of Z. We show how violations of normality in Z can lead to asymmetrical category response functions. The ability to test this normality assumption is beneficial from both a statistical and substantive perspective. In a simulation study, we show the viability of the model and investigate the specificity of the effects. We apply the model to a dataset on affect and a dataset on alexithymia.     

Neuropsychological Sequelae of PTSD and TBI Following War Deployment among OEF/OIF Veterans

Posttraumatic stress disorder (PTSD) and mild traumatic brain injury (mTBI) are highly prevalent among Veterans of the conflicts in Iraq and Afghanistan. These conditions are associated with common and unique neuropsychological and neuroanatomical changes. This review synthesizes neuropsychological and neuroimaging studies for both of these disorders and studies examining their co-occurrence. Recommendations for future research, including use of combined neuropsychological and advanced neuroimaging techniques to study these disorders alone and in concert, are presented. It is clear from the dearth of literature that addiitonal studies are required to examine and understand the impact of specific factors on neurocognitive outcome. Of particular relevance are temporal relationships between PTSD and mTBI, risk and resilience factors associated with both disorders and their co-occurrence, and mTBI-specific factors such as time since injury and severity of injury, utilizing comprehensive, yet targeted cognitive tasks.     

Preference exploration and learning: the role of intensiveness and extensiveness of experience

In this article, the authors partition the construct of experience into intensiveness (i.e., amount) and extensiveness (i.e., breadth) and examine the impact of the two specific types of experience on preference learning. In the first three studies, the authors' theory that experience can be partitioned into intensiveness (i.e., amount) and extensiveness (i.e., breadth) of experience and that extensiveness has a greater impact on preference learning is supported in environments where prior experience is measured. Further, in study 4 they demonstrate that extensiveness or breadth of experience exerts a larger influence on preference learning in an experiment where each unique type of experience is manipulated as well as measured.     

Shared Decision-Making Among Caregivers and Health Care Providers of Youth with Type 1 Diabetes

The present study aimed to examine perceptions of shared decision-making (SDM) in caregivers of youth with type 1 diabetes (T1D). Interview, survey data, and HbA1c assays were gathered from caregivers of 439 youth with T1D aged 3–18 years. Caregiver-report indicated high perceived SDM during medical visits. Multivariable linear regression indicated that greater SDM is associated with lower HbA1c, older child age, and having a pediatric endocrinologist provider. Multiple logistic regression found that caregivers who did not perceive having made any healthcare decisions in the past year were more likely to identify a non-pediatric endocrinologist provider and to report less optimal diabetes self-care. Findings suggest that youth whose caregivers report greater SDM may show benefits in terms of self-care and glycemic control. Future research should examine the role of youth in SDM and how best to identify youth and families with low SDM in order to improve care.     

Contextual Factors for Research on Psychological Therapies for Aboriginal Australians

This paper is to provide a commentary to Can cognitive behavioural therapy (CBT) be effective for Aboriginal Australians? Perspectives of Aboriginal practitioners trained in CBT. It is inspiring that this study has found that CBT can play a useful role in therapy for Aboriginal and Torres Strait Islander people but the outcomes need to be considered with caution. CBT can provide a useful tool when working with Aboriginal and Torres Strait Islander people, but in itself is not adequate for a number of reasons. Firstly, it is not culturally responsive but can be part of an approach that might be culturally appropriate. The authors are compelled at this point to give a history of mental health and Aboriginal and Torres Strait Islander people to provide a background context to the discussion and to illustrate why some psychological approaches such as CBT can only ever be part of the tools that might be used in a broader framework, that is required to address and strengthen Aboriginal and Torres Strait Islander people's well‐being.     

TURNING STONES INTO BREAD: DEVELOPING SYNERGISTIC SCIENCE/RELIGION APPROACHES TO THE WORLD FOOD CRISIS

The Institute on Religion in an Age of Science (IRAS) has a long history of delivering conferences addressing topics of interest in the field of science and religion. The following papers from the 2013 summer conference on “The Scientific, Spiritual, and Moral Challenges in Solving the World Food Crisis” are, in keeping with the eclectic nature of these conferences, very different in content and approach. Such differences underline the challenges of synergistically combining scientific and religious insights to increase understanding of global problems and their possible solutions. This in turn reflects deeper questions about the purpose and nature of the science/religion dialogue. These papers suggest various ways in which the two perspectives can be combined in the pursuit of building better understandings of food‐related issues, as well as highlighting difficulties and limitations which need to be addressed if the fruits of such dialogue are to make a wider impact. As such they serve as useful pointers for how this type of science/religion interaction might be further developed and deployed.
