A factor model approach for the joint segmentation with between‐series correlation

We consider the detection of changes in the mean of a set of time series. The breakpoints are allowed to be series specific, and the series are assumed to be correlated. The correlation between the series is supposed to be constant along time but is allowed to take an arbitrary form. We show that such a dependence structure can be encoded in a factor model. Thanks to this representation, the inference of the breakpoints can be achieved via dynamic programming, which remains one the most efficient algorithms. We propose a model selection procedure to determine both the number of breakpoints and the number of factors. This proposed method is implemented in the FASeg R package, which is available on the CRAN. We demonstrate the performances of our procedure through simulation experiments and present an application to geodesic data.     

Racial segregation and the limits of international undergraduate student diversity

This study challenges the assertion that the influx of Asian international undergraduate students in universities across the United States creates richer educational and social environments. Drawing on qualitative research at a public university with a large number of Asian international students, this article examines how Asian American student leaders and their organization took on the difficult institutional task of actualizing the diversity of these new students in a racially segregated campus. We found that instead of viewing racial segregation practices as possibly tied to racial discrimination and privileges of normative whiteness, students expressed both support and resistance to Asian international students in race-neutral language of comfort and organizational differences that reflects the dominant ideology of colorblindness. We argue that any claims to the benefits of international student diversity must take serious account of colorblind racism and the experiences of racial marginalization and racial segregation among domestic minority and international students.     

Volatilité des revenus salariaux et volatilité de l'emploi chez les jeunes en Europe

Les auteurs fournissent de nouveaux éléments d'appréciation sur la volatilité des revenus salariaux et de l'emploi chez les jeunes Européens après la crise de 2008. L'analyse, qui repose sur des données de la base EU‐SILC (2004–2013), révèle des différences de niveaux et de tendances importantes entre les pays. Sans surprise, l'instabilité augmente après la crise, mettant fin au recul enregistré précédemment. Une analyse de variance montre que les jeunes des pays d'Europe méridionale sont particulièrement exposés à la volatilité de l'emploi. Une régression à effets fixes permet d'associer certaines institutions (prestations de chômage et législation protectrice de l'emploi) à une baisse de l'instabilité.     

Policy Shift: South Africa’s Old Age Pensions’ Influence on Perceived Quality of Life

Noncontributory pensions serve as an important resource for poverty-affected households in low- and middle-income countries. This study explores how a recent policy change to pension receipt influences perceived quality of life among older South Africans. We use survey data from the longitudinal World Health Organization Study on global AGEing and adult health and from the Agincourt Health and Socio-Demographic Surveillance System census. We find pension receipt to have a positive impact on both men’s and women’s perceived quality of life. These findings hold when controlling for prior well-being status. We find a significant moderating factor of physical limitations on the relationship between pension receipt and quality of life. Individuals reporting the highest levels of physical limitation report a larger increase in their quality of life upon pension receipt than those with less severe physical limitations. We conclude that despite the well-documented household income-pooling in this population, pension receipt still leads to a significant positive impact on pensioners’ perceived quality of life.     

Using WhatsApp for a homeless count

The study analyses how the use of instant messaging (WhatsApp) alongside other ICT tools is adequate to complement the count of homeless people in an area. In particular, it describes the methodology used in order to organize the first official count of homeless people in Girona (Catalonia, Spain). Given that this is the first count of individuals experiencing homelessness in the city, it is difficult to say that it is an improvement, but it could be suggested that the app might make the future counts more efficient. Both professional and volunteers and homeless people used WhatsApp to send information. A total of 283 homeless people were detected. Results show that the usage of this application optimized the results of the count. 36.1% of the data were obtained online. Homeless people, who were reluctant to contact directly with the professional team, used WhatsApp to communicate with them, adding up to 19.4% of the data obtained. Results show how communication between homeless people and health and mental health services can be potentially improved with this type of application.     

Analysing the dimensions of social pedagogy from an international perspective

Over recent years, social pedagogy has emerged or undergone transformation processes in many countries, justifying the need to understand how it is being shaped and transformed throughout the world. However, conceptual ambiguity and lack of a homogenous and unified theoretical body accentuate the dilemma of whether social pedagogy is a specific area of knowledge, a professional field, a research field or all of these at once. We have moved into a stage where we do not have an immediate answer as to what social pedagogy is, what kind of knowledge it is or what its specific working methods are. This research aims to provide a comprehensive and rigorous analysis of social pedagogy from an international perspective. The methodology employed herein is the Delphi method, using three questionnaires in three different phases. Based on the individual contributions of a group of renowned experts from different countries, our aim is to build a global, current and integrated view of social pedagogy.     

Measuring and reporting campus sexual assault: Privilege and exclusion in what we know and what we do

As awareness of and national attention to campus sexual assault in the U.S. has grown, efforts to study and respond to the problem have increased. While these efforts are to be applauded, they have yet to fully challenge or correct the privileged and exclusive perspectives and assumptions regarding student experiences of campus sexual assault. Specifically, the experiences of white, heterosexual, cisgender, middle‐class, and American citizens who are students at primarily elite, traditional colleges and universities are taken as the norm, while experiences of students of color, LGBTQ students, and international students are neglected. Here we examine two primary sources of information regarding campus sexual assault: large‐scale self‐report surveys and individual reporting to authorities. We first review the content of select large‐scale surveys used to gather and measure self‐reported data from students on the scope, prevalence, and character of campus sexual assault, and identify areas of omission and neglect regarding marginalized students. We then review literature on barriers to reporting to authorities specific to these groups that further exclude them from our understanding of the problem. We end with recommendations for improved efforts to study and respond to campus sexual assault that are more inclusive and comprehensive.     

Tracking the defining moments of crisis process and practice

Crisis holds the potential for profound change in organizations and industries. The past 50 years of crisis management highlight key shifts in crisis practice, creating opportunities for multiple theories and research tracks. Defining crises such as Tylenol, Exxon Valdez, and September 11 terrorist attacks have influenced or challenged the principles of best practice of crisis communication in public relations. This study traces the development of crisis process and practice by identifying shifts in crisis research and models and mapping these against key management theories and practices. The findings define three crisis domains: crisis planning, building and testing predictive models, and mapping and measuring external environmental influences. These crisis domains mirror but lag the evolution of management theory, suggesting challenges for researchers to reshape the research agenda to close the gap and lead the next stage of development in the field of crisis communication for effective organizational outcomes.     

Collaboration outcomes in a public sector: impact of governance,leadership, interdependence and relational capital

Collaboration between public agencies is critical to address social issues effectively. The main objective of this research was to identify the factors that lead to successful achievement of desired collaboration outcomes that could eventually lead to societal outcomes. The factors identified were: transformational leadership, governance, interdependence, and relational capital. An integrated framework was developed based on collaboration governance framework (CGF) of Ansell and Gash (J Public Adm Res Theory 18:543–571, 2008). The CGF framework has integrated the following four broad variables that are responsible for achieving the desired collaboration outcomes: starting conditions, institutional design, leadership, and collaborative process. The study was conducted in Malaysia by sending questionnaires to 500 officers in various ministries who were involved in planning, formulating, and implementing public policies. The main findings of this study are: (1) transformational leadership influences governance, interdependence, relational capital, and collaboration outcomes; (2) governance has impact on relational capital, interdependence, and collaboration outcomes; (3) relational capital and interdependence result in positive collaboration outcomes; (4) dimensions of governance are inter-related; and (5) interdependence and relational capital are strongly correlated. This research adds significantly to the literature on collaborative governance. The implications and limitations of the study are discussed.
