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.     

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.     

Orientalism and Russian speaking minority regions in Europe: representing Narva

ABSTRACT

This paper uses the concept of orientalism to propose a framework for understanding the relationship between international news media and individual representations of minority groups in Europe. Even though the case study focuses on Narva, Estonia, the model here provides a basis for comparing the identity formation practices, particularly of geographically separated Russian speaking minority groups in Europe. Narva’s large Russian speaking population and geographical proximity to Russia have been pinpointed as security concerns due to the convenient source of information and mass media sponsored by the Russian Federation causing a misrepresentation of Russian speaking minority groups in international media.     

How discrimination in adoptive,foster, and medical systems harms LGBTQ+ families: Research on the experiences of prospective parents

Abstract

LGBTQ+?people face multiple challenges to parenthood because of barriers such as discriminatory legislation and policies influencing foster parenting, adoption, and reproductive health services. This study documents these obstacles and examines their impact through a grounded theory analysis of interviews of LGBTQ+?prospective parents. Stressors included social isolation, unnecessary medicalization, prohibitive financial costs related to accessing social and medical services (sometimes across state lines), and being denied services, parental leave, and insurance coverage. Findings indicate that heteronormative attitudes and discrimination can lead to debilitating and enduring harm upon the economic, emotional, and relational well-being of growing LGBTQ+?families.     

Power play: the use of space to control and signify power in the workplace

ABSTRACT

The findings of this article emerge from an eight-month study examining career identity practices amongst a select group of fitness professionals in the U.K. We examine how the inter-relationship between physical and social space can denote how power is acquired, displayed, and used by individuals interacting in a shared space. The findings show that power is signified through spatial practices as individuals negotiate through triadic space, creating an identity of space and place for both trainer and client that identifies power, and signifies who has power. Fitness professionals with high levels of symbolic power are able to subvert organizational spatial norms to better serve themselves and their clients, while those with lower levels of symbolic power are forced to, or choose to, negotiate or abdicate space to others. These findings are relevant to a wide range of occupations where self-employment and contract workers interact in shared space.     

Protesting the police: anti-police brutality claims as a predictor of police repression of protest

Police face a unique dilemma when policing protests that explicitly target them, such as the anti-police brutality protests that have swept the United States recently. Because extant research finds that police response to protests is largely a function of the threat – and especially the threat to police – posed by a protest, police may repress these protests more than other protests, as they may constitute a challenge to their legitimacy as a profession. Other research suggests police agencies are strongly motivated by reputational concerns, suggesting they may treat these protests with special caution to avoid further public scrutiny. Using data on over 7,000 protests events in New York over a 35-year period from 1960 to 1995, I test these competing hypotheses and find that police respond to protests making anti-police brutality claims much more aggressively than other protests, after controlling for indicators of threat and weakness used in previous studies. Police are about twice as likely to show up to anti-police brutality protests compared with otherwise similar protests making other claims and, once there, they intervene (either make arrests, use force or violence against protesters, or both) at nearly half of these protests, compared to about one in three protests making other claims.     

Beratungsforschung mit,für oder ohne die Praxis?

This article deals with the extent to which consulting research and consulting practice are pulling in the same direction or whether the gap between them still seems insurmountable. Therefore we examine the literature on consulting research, report what kind of research coaching practitioners would consider beneficial and introduce first findings from an empirical survey in which coaching practitioners were asked about their motivation for—or against—taking part in coaching research.     

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.     

Deconstructing maternal sensitivity: Predictive relations to mother‐child attachment in home and laboratory settings

Despite the well‐documented importance of parental sensitivity for child development, there is a lack of consensus regarding how best to assess it. We investigated the factor structure of maternal caregiving behavior as assessed at 12 months by the Maternal Behavior Q‐Sort (Pederson & Moran) with 274 mother‐infant dyads. Subsequently, we examined associations between these empirically‐derived dimensions and child attachment, assessed in the home and laboratory (final N = 157). Three dimensions of maternal behavior were identified, corresponding fairly closely to Ainsworth's original scales. They were labeled Cooperation/Attunement, Positivity, and Accessibility/Availability. Only Cooperation/Attunement consistently predicted home‐based attachment at 15 months and 2 years, and at comparable strength to the overall sensitivity score, suggesting that this construct may be central to sensitivity. At 18 months, compared to their primarily secure counterparts, different types of laboratory‐assessed insecure attachment were associated with different patterns of maternal behavior. Mothers in avoidant relationships (n = 18) were low on Cooperation/Attunement and Accessibility/Availability, but fairly high on Positivity. Mothers of disorganized infants (n = 11) were Cooperative/Attuned but somewhat less Positive toward, and less Accessible/Available to, their infants. A multidimensional approach to parental behavior may facilitate the identification of parenting precursors of insecure parent‐child relationships.
