How does transnationalism affect the perceptions of discrimination among Dominicans,Puerto Ricans and Cubans?

Transnationalism provides first- and second-generation immigrants with a dual frame of reference that shapes perceptions of their experiences in the United States (USA). For Caribbean Latino/as, who are likely targets of racial and ethnic discrimination, transnational ties can impact their interpretations of discriminatory incidents. This study explores the relationship between transnationalism and perceptions of discriminatory experiences of 1,577 Caribbean Latino/as Dominicans (n = 335), Cubans (n = 420), and Puerto Ricans (n = 822). These Latino/as were selected from the 2006 Latino National Survey. Suggested by our study findings, after having controlled for demographic and immigration variables, transnational Caribbean Latino/as are more likely to perceive discrimination than those not maintaining transnational ties. We conclude with a discussion of the research and practice implications.     

Automated statistical methods for measuring the strength of block ciphers

A block cipher is one of the most common forms of algorithms used for data encryption. This paper describes an efficient set of statistical methods for analysing the security of these algorithms under the black-box approach. The procedures can be fully automated, which provides the designer or user of a block cipher with a useful set of tools for security analysis.     

Growing Pains: How Risk Perception and Risk Communication Research Can Help to Manage the Challenges of Global Population Growth

In 2011, the global human population reached 7 billion and medium variant projections indicate that it will exceed 9 billion before 2045. Theoretical and empirical perspectives suggest that this growth could lead to an increase in the likelihood of adverse events (e.g., food shortages, climate change, etc.) and/or the severity of adverse events (e.g., famines, natural disasters, etc.). Several scholars have posited that the size to which the global population grows and the extent to which this growth increases the likelihood of adverse outcomes will largely be shaped by individuals’ decisions (in households, organizations, governments, etc.). In light of the strong relationship between perceived risk and decision behaviors, it is surprising that there remains a dearth of empirical research that specifically examines the perceived risks of population growth and how these perceptions might influence related decisions. In an attempt to motivate this important strand of research, this article examines the major risks that may be exacerbated by global population growth and draws upon empirical work concerning the perception and communication of risk to identify potential directions for future research. The article also considers how individuals might perceive both the risks and benefits of population growth and be helped to better understand and address the related issues. The answers to these questions could help humanity better manage the emerging consequences of its continuing success in increasing infant survival and adult longevity.     

A Test of Basic Assumptions of Affective Events Theory (AET) in Call Centre Work1

Based on data from 2091 call centre representatives working in 85 call centres in the UK, central assumptions of affective events theory (AET) are tested. AET predicts that specific features of work (e.g. autonomy) have an impact on the arousal of emotions and moods at work that, in turn, co‐determine job satisfaction of employees. AET further proposes that job satisfaction is an evaluative judgement that mainly explains cognitive‐based behaviour, whereas emotions and moods better predict affective‐based behaviour. The results support these assumptions. A clear separation of key constructs (job satisfaction, positive and negative emotions) was possible. Moreover, correlations between several work features (e.g. supervisory support) and job satisfaction were, in part, mediated by work emotions, even when controlling for gender, age, call centre type (in‐house versus outsourced centres) and call centre size. Predictions regarding consequences of satisfaction and affect were partly corroborated as continuance commitment was more strongly related to job satisfaction than to positive emotions. In addition, affective commitment and health complaints were related to both emotions and job satisfaction to the same extent. Thus, AET is a fruitful framework for explaining why and how specific management strategies used for designing work features influence important organizational attitudes and well‐being of employees.     

Management,Competition and Professional Practice: Medicine and the Marketplace

Within the context of the creation of the internal market for health care, the paper examines the role of clinical directors, that is doctors who have retained their professional clinical positions whilst at the same time assumed roles as managers within increasingly well-defined corporate organizations providing health care. This represents considerable change from previous contexts in which doctors could always contract out of difficult managerial decisions. The role of clinical director is examined in terms of its own directorate and its involvement in contracting, co-operation and competition both within its own corporate organization and within the wider market place for health. Key issues are raised for the individuals and organization by these changes, they are discussed in terms of time, succession, managing colleagues, financial and human resources, market behaviour, support and terms of reference. These changes occasion wider discussion in terms of the challenge of coping with future demands for innovation, changes in the distribution of power within an emerging market for health care and the relationship among health care organizations, professionals and lay clients.     

The Color Paradigm: The Impact of Colorism on the Racial Identity and Identification of Latinas

Existing research has provided scant analysis on the impact of colorism or skin color privilege and stigma on racial identity and identification among Latinos/as. This article explores the dynamics of colorism and the impact on racial identity and identification among Latinos/as of varying phenotypes. The experiences of a subset of eight Caribbean Latinas and one Chicana are used to illustrate how Latinas negotiate their racial identification and survive experiences of both stigma and privilege within the U.S. context. The article concludes with implications for social work research, practice, and pedagogy.     

Beyond polyphony: Open Dialogue in a Women’s Shelter in Australia as a possibility for supporting violence‐informed practice

Open Dialogue is a family/social network‐centered psychotherapeutic approach to responding to people in crisis and distress. In 2017, Open Dialogue network meetings were implemented in an Australian inner‐city shelter for disadvantaged women. The aim of this study was to explore the experience of participating in these meetings from the perspective of service users and Open Dialogue practitioners. Qualitative interviews were completed with thirteen participants (six service users and seven practitioners) and analyzed thematically. The findings suggested that dialogical processes created safety by attending to multiple voices in nonviolent ways that reduced perceived hierarchies. Notions of expertise were renegotiated, which allowed the women to feel heard in significant ways that were different from their previous experiences with other social and healthcare services. Open Dialogue is an approach that can meaningfully attend to some of the power relations within which women live and within which social and health care services are provided.
