The Psychometric Properties of the Early Development Instrument: A Rasch Analysis Based on Swedish Pilot Data

The Early Development Instrument (EDI) is a population measure and an indicator of children’s developmental health before entering the school system. EDI-Sweden was translated and adapted from EDI-Canada. In 2011 a pilot study was conducted, as a first step of the preparations for nationwide implementation of EDI in Sweden. The purpose of the study is to analyse the psychometric properties of EDI-Sweden. Data about 116 5-year-old children were collected at ten preschools in two municipalities. EDI consists of 104 core items in five domains: physical health and well-being, social competence, emotional maturity, language and cognitive development, communication skills and general knowledge. Preschool teachers completed a web based questionnaire for each child. The data were analysed using the unidimensional Rasch model. With exception for the domain of physical health and well-being the Rasch analysis showed satisfying psychometric properties of EDI after removal of some misfitting items. In these four domains no items showed disordered thresholds and the reliability was good, indicated by person separation index values of 0.73 or higher. Tentative analyses of Differential Item Functioning (DIF) showed that some items didn’t work invariantly across genders, suggesting that the DIF-items should be split into gender specific items. Due to the relatively small sample size the results can’t provide definite answers but tentative indications of the psychometric properties of the EDI-Sweden. As a whole the Rasch analysis provides ground for cautious optimism for large scale assessment of EDI-Sweden enabling more thorough and finer level analysis of the instrument.     

Reassessing Tradeoffs Inherent to Simultaneous Maintenance and Production Planning

Previous work has considered the simultaneous (as opposed to sequential) optimization of a maintenance policy and a production policy in a multi‐product setting with random yield and product mix constraints. One of the sequential approaches to which the simultaneous approach is compared is a so‐called first‐come‐first‐served (FCFS) approach, i.e., an approach that generates randomized production policies that do not depend on the deterioration state of the machine. However, the model formulation for this approach does not generate policies consistent with this FCFS notion. Therefore, we present a revised FCFS model and analyze its performance using an existing experimental design. The results suggest that previous work overestimates the degree to which a FCFS approach is suboptimal, and underestimates the value of simultaneously optimizing the maintenance and production decisions. Lastly, we conduct additional experiments which suggest that the joint impact of using both simultaneous optimization and a deterioration dependent production policy is quite significant.     

Communities respond to elder abuse

This article traces the development of services to prevent and treat elder abuse over a twenty-year time span. It begins by describing the various forms of elder abuse and the challenges they pose to service providers and program developers. Also described are abuse reporting statutes, the roles of various agencies involved in abuse investigations and responses, services commonly needed by victims, funding sources, and common impediments to service delivery.     

Deception in psychology: moral costs and benefits of unsought self-knowledge

Is it ethically permissible to use deception in psychological experiments? We argue that, provided some requirements are satisfied, it is possible to use deceptive methods without producing significant harm to research participants and without any significant violation of their autonomy. We also argue that methodological deception is at least at the moment the only effective means by which one can acquire morally significant information about certain behavioral tendencies. Individuals in general, and research participants in particular, gain self-knowledge which can help them improve their autonomous decision-making. The community gains collective self-knowledge that, once shared, can play a role in shaping education, informing policies and in general creating a more efficient and just society.     

A Two-Latent-Class Model for Smoking Cessation Data with Informative Dropouts

Non ignorable missing data is a common problem in longitudinal studies. Latent class models are attractive for simplifying the modeling of missing data when the data are subject to either a monotone or intermittent missing data pattern. In our study, we propose a new two-latent-class model for categorical data with informative dropouts, dividing the observed data into two latent classes; one class in which the outcomes are deterministic and a second one in which the outcomes can be modeled using logistic regression. In the model, the latent classes connect the longitudinal responses and the missingness process under the assumption of conditional independence. Parameters are estimated by the method of maximum likelihood estimation based on the above assumptions and the tetrachoric correlation between responses within the same subject. We compare the proposed method with the shared parameter model and the weighted GEE model using the areas under the ROC curves in the simulations and the application to the smoking cessation data set. The simulation results indicate that the proposed two-latent-class model performs well under different missing procedures. The application results show that our proposed method is better than the shared parameter model and the weighted GEE model.     

The Demand for Lotto: The Role of Conscious Selection

This article presents estimates of the elasticity of demand for lottery tickets using time series data in which there is variation in the expected value of a lottery ticket induced by rollovers. An important feature of our data is that there are far more rollovers than expected given the lottery design. We find strong evidence that individuals do not choose their lottery numbers uniformly from a uniform distribution—that is, conscious selection. We use our estimates to derive the inverse supply function for the industry, and this enables us to identify the demand elasticity. We find the price elasticity to be close to unity, which implies that the operator is revenue maximizing—which is the regulator's objective.     

Evaluating leadership coaching: A review and integrated framework

Leadership coaching reflects an evolving dynamic between the client and coach that is qualitatively different from most approaches to leadership development and therefore holds particular challenges for evaluation. Based on reviews of academic and practitioner literatures, this paper presents an integrated framework of coaching evaluation that includes formative evaluations of the client, coach, client–coach relationship, and coaching process, as well as summative evaluations based on coaching outcomes. The paper also includes a quantitative synthesis examining evaluation methodologies in 49 leadership coaching studies. The results revealed that self-reported changes in clients' leadership behaviors are the most frequently assessed coaching outcome, followed by clients' perceptions of the effectiveness of coaching. Recommendations to advance coaching evaluation research include the creation of collaborative partnerships between the evaluation stakeholders (client, coach, client's organization, and coaching organization) to facilitate systematic formative evaluations, the collection of multi-source and multi-level data, and the inclusion of distal outcomes in evaluation plans.     

Propensity for self-development of leadership attributes: Understanding,predicting, and supporting performance of leader self-development

Little systematic research has been reported to advance understanding of the characteristics associated with individuals who initiate self-development activities to grow leadership skills. The purpose of the present research was to examine cognitive, dispositional, and motivational precursors to the propensity to engage in leadership self-development. A second purpose was to examine the role of organizational support on the relationships between self-development propensity and reported self-development activities. Over 400 junior-military leaders participated in a three-stage survey administration designed to test a structural model of leader self-development. Results indicate that a person having individual characteristics related to mastery, work, and career-growth orientations displayed more motivation to perform leader self-development and more skilled at performing instructional and self-regulatory processes. Higher self-development motivation and skill resulted in greater reported self-development activities. Surprisingly, organizational support reduced the magnitude of this relationship. This study concludes with implications for future research on and practice of leader self-development activities.     

The role of nonverbal sensitivity in childhood psychopathology

Two samples of boys were compared on their sensitivity to nonverbal communication: boys not in treatment (sampled from elementary school populations) and boys in treatment (sampled from community mental health clinics). Three main decoding tasks assessed the boys' ability to identify, classify, and predict nonverbal displays. Parent and self appraisals on nonverbal sensitivity were also collected. Results indicated that clinic-recruited boys performed less well than school-recruited boys on the three decoding tasks, but there were no significant differences in the self or parent appraisals. Older boys performed better than younger boys on the decoding tasks, but were not differentiated by self or parent appraisals. Further analyses revealed a significant positive correlation between the level of the boys' social incompetence and poor self-control and the number of decoding errors the boys made on the dominant/submissive but not the negative/positive dimension of nonverbal displays. In addition, the interrelationship of the nonverbal skills appeared to differ across clinic- and school-recruited boys. Results are discussed in terms of their relevance for understanding child psychopathology and their implications for child assessment and treatment.     

Riding the Resource Roller Coaster: Understanding Socioeconomic Differences between Mining Communities*

Abstract Social science studies of mining communities suggest that the well‐being of these company towns varies a great deal. Yet the literature has not thoroughly explained the sources of that variation, especially its potential relationship to the resource itself. In order to clarify our understanding of socioeconomic well‐being, this paper likens the experience of being mining dependent to riding a roller coaster. While many mining areas experience volatile economic conditions, key characteristics and responses of the communities, companies, and resource alter the ride. To illustrate this concept, the paper examines employment trends in two metal‐mining regions of the Midwest and finds that employment was more volatile in one area than the other. The reasons for the differences between the communities are explored. The paper concludes that paying greater attention to the context in which mining occurs and to the resource itself may help clarify the impacts of mining on local communities.
