Stress–strength models with more than two states under exponential distribution

In the stress–strength models, analysis is based on the reliability of the system where the system is either in operational state or in failure state. Ery?lmaz (2011 Ery?lmaz, S. (2011). A new perspective to stress–strength models. Ann. Inst. Stat. Math. 63(1):101–115.[Crossref], [Web of Science ®] , [Google Scholar]) introduced the stress–strength reliability in a different framework assigning more than two states to the system depending on the difference between strength and stress values. Unlike Ery?lmaz (2011 Ery?lmaz, S. (2011). A new perspective to stress–strength models. Ann. Inst. Stat. Math. 63(1):101–115.[Crossref], [Web of Science ®] , [Google Scholar]), the present article deals with the ratio of the strength and stress values when the stress and strength follow independent exponential distributions. This article presents in detail the estimation aspect of the multistate stress–strength reliability function.

Tuning into performance and satisfaction in nonprofit orchestras: One link between transformational leadership and satisfaction is through reduction in conflict

In this study, we tested hypotheses concerning volunteers' not‐for‐profit work, specifically the relations of transformational leadership with performance and satisfaction as well as the question of how task and relationship conflict fit into these relations. We argue that conflicts are detrimental to satisfaction and performance and that the frequency of conflict can be reduced through transformational leadership. We analyzed data from a large sample of lay orchestra musicians (N = 1,535) and found that musicians' perceptions of their conductors' transformational leadership style were positively related to both the performance and satisfaction of the musicians. Furthermore, we found that conflict mediated the relation between transformational leadership and satisfaction to some extent. The mediation occurred via the frequencies of both task and relationship conflicts even though the frequency of conflict was quite low in this sample in general.     

Forecast Combination and Model Averaging Using Predictive Measures

We extend the standard approach to Bayesian forecast combination by forming the weights for the model averaged forecast from the predictive likelihood rather than the standard marginal likelihood. The use of predictive measures of fit offers greater protection against in-sample overfitting when uninformative priors on the model parameters are used and improves forecast performance. For the predictive likelihood we argue that the forecast weights have good large and small sample properties. This is confirmed in a simulation study and in an application to forecasts of the Swedish inflation rate, where forecast combination using the predictive likelihood outperforms standard Bayesian model averaging using the marginal likelihood.     

Older Women and Cosmetic Tattooing Experiences

Aging for the older women in the 21st century is more than medical issues. In this study, 62 women (ages 51–81+) obtained a total of 97 permanent makeup procedures. Procurement cues included self-improvement and friend's appearance, consistent with internal, external, and appearance perspectives of body image. Poor eyesight was also of concern (14/23%). Actual benefits included saving makeup time and money (external), while achieving personal goals (internal). This study seems to confirm that for these older women, body image remains important, especially qualities of the face. They did not shed their internal, external, nor appearance concerns associated with body image, as they aged.     

Making the case for ongoing and interactive organizational ethics training

This essay discusses the importance of ongoing and interactive ethics training within the scope of human resource development (HRD) practice. Furthermore, the essay adds to the discourse that relates HRD practice and theory involving ethics training.     

The Trajectory of Concurrent Motor and Vocal Behaviors Over the Transition to Crawling in Infancy

To document the trajectory of motor and vocal behaviors in real and developmental time, we observed infants at each of four biweekly naturalistic play sessions over the transition to crawling. An exhaustive and mutually exclusive coding scheme documented all vocalizations and postures. Odds ratios of the likelihood of a given posture‐vocalization dyad revealed that vocalization and crawling were significantly unlikely to co‐occur at the session marking the onset of crawling. We speculate that infants’ allocation of attention over the transition to crawling prompted behavioral trade‐offs. During mastery of a novel skill, infants may have had difficulty allocating attention to multiple tasks, but with experience, a decrease in attentional load for the new skill allowed performance of simultaneous behaviors in other domains to occur.     

Household‐Level Coastal Adaptation and Its Drivers: A Systematic Case Study Review

Evidence‐based information on household‐level adaptation is an important element of integrated management of vulnerable coastal regions. A growing number of empirical studies deal with household‐level adaptation at the coast in different regions. This article provides a systematic review of these studies. We analyze studies according to how households in different parts of the world are currently adapting, or how they are intending to adapt, and identify explanatory factors for adaptation behavior and intention. We find that households implement a broad range of adaptation measures and that adaptation behavior is explained by individual factors such as socioeconomic and cognitive variables, experience, and perceived responsibilities. Nonpersonal characteristics have also been used to explain adaptation behavior and intention but have not been extensively investigated. Few studies employ qualitative research methods and use inductive approaches as well as models stemming from behavioral economics. Our findings suggest that coastal risk management policies should communicate the efficacy of household‐level adaptation, in addition to information about flood risk, in order to encourage coastal households in their adaptation activities. In this context, we discuss the role of resources and responsibility of households for their adaptation behavior. We describe the lessons learnt and formulate a research agenda on household‐level adaptation to coastal flood risk. In practice, coastal risk management policies should further promote individually driven adaptation by integrating it in adaptation strategies and processes.     

Plastic surgery in gynaecology: Factors affecting women’s decision to undergo labiaplasty. Mind the risk of body dysmorphic disorder: A review

ABSTRACT

Aesthetic surgery of the female genitalia is on the rise. Many procedures are performed. Body dysmorphic disorder (BDD) is a psychiatric disorder and often goes unrecognized in plastic surgery. This review examines actual knowledge of plastic surgery in gynecology, knowledge of motivational factors of women, and BDD. We carried out a systematic electronic search. We used a combination of relevant keywords to construct the search strategy. Included studies were systematic reviews or primary studies published 1990–2017 and containing information about BDD. Reviewers independently assessed study eligibility, extracted data, and assessed quality, undertaking narrative synthesis. The research revealed a variety of plastic procedures available and why women consider undergoing labia reduction surgery.
