On the Evolutionary Defense of Scientific Antirealism

Van Fraassen (The scientific image, Oxford University Press, Oxford, 1980) claims that successful theories exist today because successful theories survive and unsuccessful ones die. Wray (Erkenntnis 67:81–89, 2007; Erkenntnis 72:365–377, 2010) appeals to Stanford’s new pessimistic induction (Exceeding our grasp: science, history, and the problem of unconceived alternatives, Oxford University Press, Oxford, 2006), arguing that van Fraassen’s selectionist explanation is better than the realist explanation that successful theories exist because they are approximately true. I argue that if the pessimistic induction is correct, then the evolutionary explanation is neither true nor empirically adequate, and that realism is better than selectionism because realism explains more phenomena in science than selectionism.     

Developmental climate: A cross-level analysis of voluntary turnover and job performance

This research investigates the influence of shared perceptions of developmental climate on individual-level perceptions of organizational commitment, engagement, and perceived competence, and whether these attitudes mediate the relationship between developmental climate and both individual voluntary turnover and supervisor-rated job performance. Survey data were collected from 361 intact employee–supervisory mentoring dyads and matched with employee turnover data collected one year later to test the proposed framework using multilevel modeling techniques. As expected, shared perceptions of developmental climate were significantly and positively related to all three individual work attitudes. In addition, both organizational commitment and perceived competence were significant mediators of the positive relationship between shared perceptions of developmental climate and voluntary turnover, as well as shared perceptions of developmental climate and supervisor-rated job performance. By contrast, no significant mediating effects were found for engagement. Theoretical implications, limitations, and future research are discussed.     

Confirmation measures and collaborative belief updating

There are some candidates that have been thought to measure the degree to which evidence incrementally confirms a hypothesis. This paper provides an argument for one candidate—the log-likelihood ratio measure. For this purpose, I will suggest a plausible requirement that I call the Requirement of Collaboration. And then, it will be shown that, of various candidates, only the log-likelihood ratio measure \(l\) satisfies this requirement. Using this result, Jeffrey conditionalization will be reformulated so as to disclose explicitly what determines new credences after experience.     

Moral Injury,Spiritual Care and the Role of Chaplains: An Exploratory Scoping Review of Literature and Resources

This scoping review considered the role of chaplains with regard to ‘moral injury’. Moral injury is gaining increasing notoriety. This is due to greater recognition that trauma (in its various forms) can cause much deeper inflictions and afflictions than just physiological or psychological harm, for there may also be wounds affecting the ‘soul’ that are far more difficult to heal—if at all. As part of a larger research program exploring moral injury, a scoping review of literature and other resources was implemented utilising Arksey and O’Malley’s scoping method (Int J Soc Res Methodol 8(1):19–32, 2005) to focus upon moral injury, spirituality (including religion) and chaplaincy. Of the total number of articles and/or resources noting the term ‘moral injury’ in relation to spiritual/religious issues (n = 482), the results revealed 60 resources that specifically noted moral injury and chaplains (or other similar bestowed title). The majority of these resources were clearly positive about the role (or the potential role) of chaplains with regard to mental health issues and/or moral injury. The World Health Organization International Classification of Diseases: Australian Modification of Health Interventions to the International Statistical Classification of Diseases and related Health problems (10th revision, vol 3—WHO ICD-10-AM, Geneva, 2002), was utilised as a coding framework to classify and identify distinct chaplaincy roles and interventions with regard to assisting people with moral injury. Several recommendations are made concerning moral injury and chaplaincy, most particularly the need for greater research to be conducted.     

Specifying Ability Growth Models Using a Multidimensional Item Response Model for Repeated Measures Categorical Ordinal Item Response Data

When categorical ordinal item response data are collected over multiple timepoints from a repeated measures design, an item response theory (IRT) modeling approach whose unit of analysis is an item response is suitable. This study proposes a few longitudinal IRT models and illustrates how a popular compensatory multidimensional IRT model can be utilized to formulate such longitudinal IRT models, which permits an investigation of ability growth at both individual and population levels. The equivalence of an existing multidimensional IRT model and those longitudinal IRT models is also elaborated so that one can make use of an existing multidimensional IRT model to implement the longitudinal IRT models.

The Satisfaction with Life Scale in Adolescent Samples: Measurement Invariance across 24 Countries and Regions,Age, and Gender

Measurement of adolescent life satisfaction across cultures has not received much attention in previous empirical research. The present study evaluated measurement invariance of the Satisfaction with Life Scale (SWLS) among adolescents in 24 countries and regions (N = 22,710; age range = 13–19 years; 53% female). A single-factor model with residual covariance between a pair of items tapping past life satisfaction fitted well in 19 countries and regions and showed a partial metric invariance. In a subset of nine countries and regions, partial scalar invariance was supported. Partial metric invariance across all 24 countries and regions was achieved when custom model modifications in five countries and regions were included. Three SWLS items showed evidence of noninvariance across cultures. The measurement model was found to operate similarly across gender and age. Our findings suggest that caution is needed when using the SWLS for measuring life satisfaction among adolescents from different cultures.

     

Abnormal diurnal pattern of cortisol secretion in patients after aneurysmal subarachnoid hemorrhage

Substantial evidence suggests that impairment of the hypothalamus?pituitary system can occur following an aneurysmal subarachnoid hemorrhage (aSAH). Given that the diurnal cortisol rhythm is primarily controlled by the hypothalamus?pituitary system, this study examined whether changes in diurnal cortisol rhythm occurred after aSAH. Cortisol concentrations were measured in the saliva samples collected from patients after aSAH and other types of cerebral hemorrhage (non-aSAH) in the post-awakening period and at night (21:00?h), and the cortisol awakening response (CAR) and diurnal cortisol decline were determined. The area under the cortisol curve from immediately after to 45?min after awakening (CARauc) in the aSAH patient group was comparable to that in the non-aSAH or healthy control groups. However, an obvious cortisol peak was not found after the awakening period, and the morning/nighttime cortisol ratio in the aSAH patient group was significantly lower than that in other examined groups due to higher nighttime cortisol concentrations. In aSAH patients, the CARauc and nighttime cortisol concentrations were negatively correlated with the Fisher CT grade. These results indicate that the diurnal cortisol rhythm is not regulated normally after aSAH, and cortisol secretory activity decreases as the volume of subarachnoid bleeding increases. Our findings will be helpful to understand altered hypothalamus?pituitary?adrenal axis function after aSAH.     

Development of the Motivators of and Barriers to Health-Smart Behaviors Inventory

The Motivators of and Barriers to Health-Smart Behaviors Inventory (MB-HSBI) was developed for use in identifying self-reported motivators of and barriers to the following health-promoting behaviors (called health-smart behaviors) that should occur daily to help promote health and overcome illnesses/diseases: eating a healthy breakfast, eating healthy foods and snacks, drinking healthy drinks, and engaging in physical activity. The MB-HSBI was developed through several phases as part of a multisite study on modifying and preventing obesity. A central aspect of the larger study was to identify motivators of and barriers to the targeted health-smart behaviors among African American, Asian, Hispanic, and White adults. After establishing content validity and preliminary pilot testing, the MB-HSBI was administered to a national sample of 926 culturally diverse adults. Factor analyses and most of the internal consistency results supported multiple scales and subscales measuring motivators of and barriers to each of the targeted health-smart behavior domains. Scores correlated in expected directions with health self-efficacy and with importance of health-related behavioral goals. Pending further psychometric support of the MB-HSBI, this inventory or selected scales from it may serve as flexible and novel tools for (a) assessing motivators of and barriers to health-smart behaviors in community and clinical health promotion research studies and (b) developing assessment-based, culturally sensitive intervention programs that are customized to address the motivators of and barriers to health-smart behaviors identified in target communities, particularly those communities whose members are mostly racial/ethnic minorities and/or have low family incomes.
