Development of a screen for ongoing intimate partner violence

A five-question Ongoing Abuse Screen (OAS) was developed to evaluate ongoing intimate partner violence. Our hypothesis was that the OAS was more accurate and more likely to reflect ongoing intimate partner violence than the AAS when compared to the Index of Spouse Abuse (ISA). The survey included the ISA, the OAS, and the AAS. During the busiest emergency department hours, a sampling of 856 patients completed all aspects of the survey tool. Comparisons were made between the two scales and the ISA. The accuracy, positive predictive value, and positive likelihood ratio were 84%, 58%, and 6.0 for the OAS and 59%, 33%, and 2.0 for the AAS. The OAS was more accurate, had a better positive predictive value, and was three times more likely to detect victims of ongoing intimate partner violence than the AAS. Because the OAS was still not accurate enough, we developed a new screen, based on the ISA, titled the Ongoing Violence Assessment Tool (OVAT).     

Success Factors of New Product Development: A Review of the Empirical Literature

The continuous development and market introduction of new products can be an important determinant of sustained company performance. For approximately 30 years, conceptual and empirical research has been undertaken to identify the critical success factors of new products. This paper reviews the findings of empirical work into the success factors of new product development (NPD). It is the prime objective of this work to summarize the most important findings in a compact and structured way. In addition, shortcomings of previous empirical work on NPD success factors will be discussed and suggestions for improvement in future empirical NPD studies will be made.     

Community distress predicting welfare exits: The under-examined factor for families in the united states

Using a quasi-experimental design, a sample of female welfare clients (N = 91) was followed over 32 months to compare two competing models used to describe welfare dependency. The individual deficit model suggested that clients would not engage in work activities on their own initiative and that legislative sanctions were required to force clients into employment. The ecological/community model suggested that community economic distress, rather than lack of skills or motivation, prevented clients from becoming gainfully employed. Results showed that while both models explained the rate at which clients left the welfare system, the community that one lived in was a stronger predictor of welfare exits than government programs mandating individual effort. Results revealed that many clients were employed regardless of whether or not it was mandated. Furthermore, clients who resided in lower income communities and were required to work to keep receiving welfare benefits under the new legislation, spent an average of nearly twice as much time in the welfare system (22.75 months) as individuals who faced neither stress (11.5 months). The findings highlight the need to incorporate community economic development strategies in the overall program to decrease welfare dependency, rather than focusing solely on individual remediation.     

Driving Forces Behind Informal Sanctions

This paper investigates the driving forces behind informal sanctions in cooperation games and the extent to which theories of fairness and reciprocity capture these forces. We find that cooperators' punishment is almost exclusively targeted toward the defectors, but the latter also impose a considerable amount of spiteful punishment on the cooperators. However, spiteful punishment vanishes if the punishers can no longer affect the payoff differences between themselves and the punished individual, whereas the cooperators even increase the resources devoted to punishment in this case. Our data also discriminate between different fairness principles. Fairness theories that are based on the assumption that players compare their own payoff to the group's average or the group's total payoff cannot explain the fact that cooperators target their punishment at the defectors. Fairness theories that assume that players aim to minimize payoff inequalities cannot explain the fact that cooperators punish defectors even if payoff inequalities cannot be reduced. Therefore, retaliation, i.e., the desire to harm those who committed unfair acts, seems to be the most important motive behind fairness‐driven informal sanctions.     

Infant vocalizations elicit simplified speech in childcare

Infant babbling has an important social function in promoting early language development by attracting caregiver attention and prompting parents' contingent, simplified speech, which is more learnable for infants. Here, we demonstrate that prelinguistic infant vocalizations also create learning opportunities for infants in childcare settings by eliciting simplified and more learnable linguistic information during teacher-infant interactions. We compared the rates and complexity of contingent and non-contingent verbal interactions of 34 childcare teachers during a one-on-one free play interaction with a familiar infant under their care (M = 12.6 months old). As compared to non-contingent utterances, teachers' contingent utterances included fewer unique words, a higher proportion of single-word responses, and a shorter mean length of utterances. Teachers did not change their response length based on infants' syllable type and were equally likely to respond to vowels and consonant-vowel vocalizations. Sources of individual differences in the simplification effect related to infant behaviors and teacher characteristics are discussed. The results parallel previous findings demonstrating the simplification effect in parent-infant interactions. That teachers also show this simplification effect when responding to infant vocalizations suggests the power of infant prelinguistic vocalizations for organizing caregiver attention in various settings to elicit simplified, learnable language.     

Relational Contracts and the Nature of Market Interactions

We provide evidence that long‐term relationships between trading parties emerge endogenously in the absence of third party enforcement of contracts and are associated with a fundamental change in the nature of market interactions. Without third party enforcement, the vast majority of trades are initiated with private offers and the parties share the gains from trade equally. Low effort or bad quality is penalized by the termination of the relationship, wielding a powerful effect on contract enforcement. Successful long‐term relations exhibit generous rent sharing and high effort (quality) from the very beginning of the relationship. In the absence of third‐party enforcement, markets resemble a collection of bilateral trading islands rather than a competitive market. If contracts are third party enforceable, rent sharing and long‐term relations are absent and the vast majority of trades are initiated with public offers. Most trades take place in one‐shot transactions and the contracting parties are indifferent with regard to the identity of their trading partner.     

Resilience: A Review Using a Grounded Integrated Occupational Approach

Resilience, the ability to adapt to adversity and endure job demands, is growing in prominence in the management literature with limited regard to occupational influences. Often examined at the individual level with fragmented conceptualizations, it can be a trait, capacity, or a process. We conduct a review of (1) management studies and (2) content from O*NET for 11 occupations and disciplinary studies taking a grounded approach to synthesize themes to develop an integrated occupational resilience framework. Our review suggests that resilience is individually and occupationally determined as part of a multi-level system. Our review shows that specific occupational tasks and contextual demands imply different connotations of what exactly “resilience” means and how contexts may constrain or foster resiliency. Occupational resilience involves (1) multiple conceptual strands related to accessing resources (trait, capacity, and processes); (2) positive and negative triggers that are occupationally distinguished; (3) different resilience types (cognitive, emotional, and physical) that vary in need, breadth, and importance across occupations; (4) a dynamic phenomenon that occurs within and across career stages; (5) both content-general, and job-specific occupational tensions; and (6) work and nonwork domains. Multi-level occupational-specific and comparative studies, adaptive performance and risk taking across the work–nonwork interface are highlighted areas for future research.     

An alternative parameterization of Bayesian logistic hierarchical models for mixed treatment comparisons

Mixed treatment comparison (MTC) models rely on estimates of relative effectiveness from randomized clinical trials so as to respect randomization across treatment arms. This approach could potentially be simplified by an alternative parameterization of the way effectiveness is modeled. We introduce a treatment‐based parameterization of the MTC model that estimates outcomes on both the study and treatment levels. We compare the proposed model to the commonly used MTC models using a simulation study as well as three randomized clinical trial datasets from published systematic reviews comparing (i) treatments on bleeding after cirrhosis, (ii) the impact of antihypertensive drugs in diabetes mellitus, and (iii) smoking cessation strategies. The simulation results suggest similar or sometimes better performance of the treatment‐based MTC model. Moreover, from the real data analyses, little differences were observed on the inference extracted from both models. Overall, our proposed MTC approach performed as good, or better, than the commonly applied indirect and MTC models and is simpler, fast, and easier to implement in standard statistical software.
