A new regression model for bimodal data and applications in agriculture

We define the odd log-logistic exponential Gaussian regression with two systematic components, which extends the heteroscedastic Gaussian regression and it is suitable for bimodal data quite common in the agriculture area. We estimate the parameters by the method of maximum likelihood. Some simulations indicate that the maximum-likelihood estimators are accurate. The model assumptions are checked through case deletion and quantile residuals. The usefulness of the new regression model is illustrated by means of three real data sets in different areas of agriculture, where the data present bimodality.     

Dealing with Migrants in the Central Mediterranean Route: A Legal Analysis of Recent Bilateral Agreements Between Italy and Libya

Dealing with the current flow of migrants flocking to the shores of southern European countries remains high on the international agenda. At the end of 2016, 276,957 migrants were waiting in Libya to cross the sea. Many of them were subject to human rights violations and abuses such as arbitrary detention, torture, unlawful killings, sexual exploitation and even slavery (IOM, 2017). The international response has been, so far, insufficient and new ideas and practices are urgently needed. After providing an overview of the legal framework and of the efforts carried out by the relevant international and regional organizations, this article focuses on recent treaties concluded between Italy and Libya, and argues that the new bilateral agreements represent an example of how States are responding to this challenge in an attempt to strike a balance between the need to strengthen the protection of migrants’ rights and the necessity to guarantee the security of national borders.     

‘What Was I Thinking?!’ Rhetorical Questions as a Technique to Identify and Explore Impasses in Therapy

Rhetorical questions emerging spontaneously in consultations can be used as a tool for developing self‐reflexivity and exploring the therapeutic alliance in the process of therapy with couples and families. This paper presents a technique based on the enunciation of rhetorical questions, which can point to an impasse in the process of therapy and contain a key to its resolution. The technique focuses on the distinctive feature of rhetorical questions as convening a paradoxical injunction: a question not intended as a question, while uttered as such. The technique in four steps is illustrated by examples from therapy, supervision, consultation, and self‐supervision. Its focus is the interlink between the therapeutic relationship and the process of therapy and it is informed by a second‐order cybernetics approach, dialogical practice, and the systemic literature on emotion. The technique can help develop curiosity in working with families, lead to unforeseen developments, and touch on prejudices not made explicit in previous therapeutic encounters. Whether we are acting as supervisors, therapists, or clients, the creation of a ‘secure enough’ context for rhetorical questions becomes critical to allow freeform exploration.     

Changing effects of family background on transitions to secondary education in the Netherlands: Consequences of educational expansion and reform

Recent developments in educational transitions research suggest a decomposition of qualitative dimensions within educational levels that are (nearly) universal. However, research on long-term trends of social stratification in the structurally tracked educational system of the Netherlands has not been published previously. In the Netherlands, the secondary educational level is divided into four hierarchical tracks which each lead to different options for subsequent educational decisions. A rapid increase of participation in the higher tracks over time however, may have changed the background-specific distribution of early track placement. This paper improves upon previous research on educational inequality by incorporating a long-term perspective into tracking research. The secondary level of the Dutch educational system is decomposed into its four tracks, using a time frame that covers cohorts that entered secondary education between 1946 and 1998. The application of multinomial logit regressions reveals that the choice of a secondary track is strongly depending on social background features, measured as education of the parents and occupational status of the father. We found linear downward trends of effects for fathers’ occupation in the intermediate tracks for the cohorts that entered secondary education between WWII and the 90s. The effects of parental education also decrease after WWII, but the trend is curvilinear and not enduring. Unexpectedly, the effects almost reach their previous level in the youngest cohort. Our results furthermore suggest that a controversial reform of the educational system in 1968 neither triggered nor accelerated equalization of secondary education, although it resulted in a growth of participation in senior general education (HAVO).     

Psychosocial Factors of Migration: Adaptation and Application of the Health Belief Model

Psychosocial factors influencing behaviour play a central role in health research but seem under‐explored in migration research. This is unfortunate because these factors, which include knowledge, attitudes, beliefs, intentions and personality traits, provide essential and potentially effective handles for linking migration and migrant‐integration policies. We demonstrate that the health belief model (HBM) conceptualization of behavioural intentions contributes constructs that can further our understanding of migration intentions, thereby broadening the foundations for migration policies. We adapt the HBM to migration behaviour and then test it empirically by using survey data on international migration from West Africa and the Mediterranean region to the European Union. The results confirm that indicators of “perceived threat to living conditions”, “perceived benefits” and “perceived barriers to migration”, “cues to action” and “self‐efficacy” contribute considerably to the explanation of migration intentions. We conclude that psychosocial factors deserve greater prominence in migration theories and empirical research, and we recommend that migration surveys consider this framework to identify relevant indicators of psychosocial factors of international migration and develop appropriate survey questions to measure them.     

Intersectional Identities and Conceptions of the Self: The Experience of Transgender People

Transgender people in the United States change genders in relation to androcentric, heterocentric, and middle‐class whitenormative cultural narratives. Drawing on ethnographic data primarily with transgender people of color, I analyze the ways in which gender, race, social class, and sexuality all combine to create specific background identities – intersected identity frames – which others attribute in interaction. We can better understand these intersected identity frames through the experiences of transgender people, who actively engage in identity management. The meanings others attach to specific combinations are foregrounded in the context of transitioning; some audiences employ dominant, white cultural narratives, while others draw upon ethnic cultural narratives. In all cases, transitioning throws the multi‐dimensionality of intersected identity frames into sharp relief against the background of intersecting social and cultural structural arrangements.     

Middle‐Class Parents and Urban Public Schools: Current Research and Future Directions

Middle‐class flight from urban public schools to suburban districts or private schools is a key source of educational inequality. Recently, however, a number of studies have focused on middle‐class and upper‐middle‐class families who have made a different choice, opting to remain in the city and send their children to neighborhood public schools. While the movement of advantaged families into urban public schools has received positive attention in the media, this growing body of research tells a more complicated story. Middle‐class families – with their economic, cultural, and social capital – can bring important resources to schools, resulting in widespread benefits. However, their engagement in urban public schools can also lead to marginalization and exclusion. We review the emergent literature on this topic, highlighting four themes: (i) parent preferences, identities, and values; (ii) the role of marketing campaigns and informal networks in attracting the middle class; (iii) the nature and consequences of middle‐class parent engagement in urban schooling; and (iv) the relationship between neighborhood change and school change. We conclude by outlining a research agenda aimed at deepening our understanding of the mechanisms by which middle‐class parent engagement in urban schooling may serve to mitigate, reproduce, or exacerbate educational inequalities.     

Musculoskeletal symptoms and workers' perception about job factors in a pulp and paper industry

The study aimed to conduct a literature review as a step of the development of a new questionnaire about the nursing workers' perception of job factors that may lead to musculoskeletal symptoms. An information synthesis was achieved by collecting data from studies that fitted the search criteria. The results showed that despite the existence of several job factors related to musculoskeletal symptoms, no specific questionnaire that evaluates this relationship was found. Therefore, this literature review presents important topics for developing the first questionnaire to analyze work activities that may contribute to pain and discomfort among nursing personnel.     

Perceptual aspects of the use of faucets (taps)

This paper presents an assessment with simulated activities with the aim of analyzing the perception of ease / difficulty of the use of faucets (taps) handles by 180 Brazilian adults. Five different handles faucets were activated for subsequent collection of perceptual data. The procedures were based on main recommendations for biomedical ethics and human research. The results indicate that handles with levers are significantly (p ≤ 0.05) easier to use. The most difficult are characterized by not having support points for the rotation (levers) or more points of pressure concentration in the hand.     

Distractions N' Driving: video game simulation educates young drivers on the dangers of texting while driving

The proliferation of portable communication and entertainment devices has introduced new dangers to the driving environment, particularly for young and inexperienced drivers. Graduate students from George Mason University illustrate a powerful, practical, and cost-effective program that has been successful in educating these drivers on the dangers of texting while driving, which can easily be adapted and implemented in other communities.
