Improved Transferability of Data‐Driven Damage Models Through Sample Selection Bias Correction

Damage models for natural hazards are used for decision making on reducing and transferring risk. The damage estimates from these models depend on many variables and their complex sometimes nonlinear relationships with the damage. In recent years, data‐driven modeling techniques have been used to capture those relationships. The available data to build such models are often limited. Therefore, in practice it is usually necessary to transfer models to a different context. In this article, we show that this implies the samples used to build the model are often not fully representative for the situation where they need to be applied on, which leads to a “sample selection bias.” In this article, we enhance data‐driven damage models by applying methods, not previously applied to damage modeling, to correct for this bias before the machine learning (ML) models are trained. We demonstrate this with case studies on flooding in Europe, and typhoon wind damage in the Philippines. Two sample selection bias correction methods from the ML literature are applied and one of these methods is also adjusted to our problem. These three methods are combined with stochastic generation of synthetic damage data. We demonstrate that for both case studies, the sample selection bias correction techniques reduce model errors, especially for the mean bias error this reduction can be larger than 30%. The novel combination with stochastic data generation seems to enhance these techniques. This shows that sample selection bias correction methods are beneficial for damage model transfer.     

Erickson’s identity theory and the importance of ethnic exploration for transnational adoptees

In an effort to promote their child’s ethnic identity development, parents of transnational adoptees regularly engage in cultural exploration activities with their children. This practice is aligned with Erik Erikson’s identity theory and constructs of exploration and commitment. Using qualitative analysis of interviews with adult adoptees, this study identifies four themes common to participants including: (1) travel to one’s birth country is a transformative experience; (2) relationships with other adoptees are important; (3) adoptees feel differently about the importance of cultural activities during childhood; and (4) adoptees feel both unique in their personal ethnic identity and have feelings of marginality.     

Organisationskultur im Spielfilm

By analyzing cinema films, specific organizational cultures can be illustrated. The culture of prison as a “total institution” is explained on the basis of the movie “The Shawshank Redemption” (1994). With regard to the developing friendship between the former banker Andy Dufresne who is innocently convicted and the homicide delinquent Ellis Boyd Redding typical characteristics of a total institution are pointed out. Furthermore, the psychological function those characteristics serve for employees, inmates and even for the society as a whole is analyzed. Central to this interpretation is thinking of the prison as a father substitute. Many interactions become comprehensible viewed in this context. Additionally, the prison represents a huge object of projection which facilitates the collective release of aggression.     

Women’s attitudes towards the medicalization of childbirth and their associations with planned and actual modes of birth

Rates of medical interventions in childbirth have greatly increased in the Western world.

‘It’s better if someone can see me for who I am’: stories of (in)visibility for students with a visual impairment within South African Universities

Issues of visibility, invisibility and the non-disabled gaze are very relevant to the lives of many disabled persons. With this article we tentatively show that, despite the physical ‘over’-visibility of disabled bodies, many intricate parts of their personhood remain obscured and invisible. Interviews with 23 students with a visual impairment revealed that they sometimes experienced stares and averted gazes from their sighted counterparts. In response, they often hid their entire impairment, or parts thereof, in an effort to conform and gain acceptance and to earn membership to a non-disabled peer group. Acceptance was often found in companionship with fellow disabled peers. Since these stories told of continuing exclusion for disabled students on tertiary grounds, further participatory research is recommended.     

Assessing Participation and Effectiveness of the Peer-Led Approach in Youth Sexual Health Education: Systematic Review and Meta-Analysis in More Developed Countries

Sexual health education for young people is crucial not only for development of norms but also for protection against vulnerabilities during this stage in life. Although several systematic reviews have examined the effectiveness of peer-led sex education, none have focused on the extent of peer participation. The purpose of this review was to evaluate peer-led sexual health education interventions in more developed countries (MDCs). Electronic and manual searches across five social science, education, and medical databases were conducted. Fifteen articles were selected in total. Most (10 of 15) studies gave low or no responsibility to peers. The majority of articles found improvements in sexual health knowledge (13 of 14) and attitudes (11 of 15) at postintervention stages. Two studies showed improved self-efficacy, and three showed behavioral changes. A preliminary synthesis of effectiveness and level of participation was done. Meta-analysis revealed a large effect on knowledge change (Hedges’ g = 0.84, 95% confidence interval [CI]: 0.43 to 1.25) and a medium effect on attitude change (Hedges’ g = 0.49, 95% CI: 0.19 to 0.80). Peer-led interventions could be a powerful tool. This review shows that this approach is effective in changing knowledge and attitudes but not behaviors. Further research and action are needed to understand optimal implementation.     

Being Transgender: The Experience of Transgender Identity Development

This article is based on a grounded theory analysis of interviews with transgender-identified people from different regions of the United States. Participants held a variety of gender identities under the transgender rubric (e.g., crossdresser, transman, transwoman, butch lesbian). Interviews explored the participants’ experiences in arriving at their gender identity. This article presents three clusters of findings related to the common processes of transgender identity development. This process was made possible by accessibility of transgender narratives that injected hope into what was a childhood replete with criticism and scrutiny. Ultimately, participants came to their identities through balancing a desire for authenticity with demands of necessity—meaning that they weighed their internal gender experience with considerations about their available resources, coping skills, and the consequences of gender transitions. The implications of these findings are considered in terms of their contribution to gender theory, research, and clinical support for transgender clients.     

Influence of Late Life Stressors on the Decisions of Older Women to Relocate into Congregate Senior Housing

Late-life stressors often require individuals to make substantial alterations in behavior and lifestyle and can affect their overall health and well-being. Relocation is a significant life stress, regardless of age. The primary aim of this study is to elucidate the push-pull factors associated with moving into congregate senior housing. The secondary aim is to investigate the decision-making processes and stresses associated with moving into a congregate living environment. Interviews were conducted with 26 women who were new residents in congregate senior housing. Relocation, as expected, was considered to be stressful, although individual differences were found among perceptions of relocation stresses. Women who had made the decision to relocate on their own showed evidence of better psychosocial well-being at the time of the move. One-quarter of the sample chose to move to provide care to another person. As the options for senior housing continue to evolve and the number of adults reaching advanced age continues to increase, it is important to understand the factors that contribute to successful adaptation. This knowledge will enable facility administrators to implement programs and procedures to assist incoming residents with acclimating to their new homes.
