Skewed zero-bound distributions and process capability indices for upper specifications

A common practical situation in process capability analysis, which is not well developed theoretically, is when the quality characteristic of interest has a skewed distribution with a long tail towards relatively large values and an upper specification limit only exists. In such situations, it is not uncommon that the smallest possible value of the characteristic is 0 and this is also the best value to obtain. Hence a target value 0 is assumed to exist. We investigate a new class of process capability indices for this situation. Two estimators of the proposed index are studied and the asymptotic distributions of these estimators are derived. Furthermore, we suggest a decision procedure useful when drawing conclusions about the capability at a given significance level, based on the estimated indices and their asymptotic distributions. A simulation study is also performed, assuming that the quality characteristic is Weibull-distributed, to investigate the true significance level when the sample size is finite.     

A general class of capability indices in the case of asymmetric tolerances

Vannman has earlier studied a class of capability indices, containing the indices C _p , C _pk , C _pm and C _pmk , when the tolerances are symmetric. We study the properties of this class when the tolerances are asymmetric and suggest a new enlargened class of indices. Under the assumption of normality an explicit form of the distribution of the new class of the estimated indices is provided. Numerical investigations are made to explore the behavior of the estimators of the indices for different values of the parameters. Based on the estimator a decision rule that can be used to determine whether the process can be considered capable or not is provided and suitable criteria for choosing an index from the family are suggested.     

Being Relaxed and Powerful: Children’s Lived Experiences of Coping with Stress

Our aim was to describe and develop an understanding of children’s lived experiences of coping with stress. Twenty‐three Swedish children, ages 10–12, wrote open letters and were interviewed. The phenomenological analysis resulted in three main themes: (i) depending on oneself, others and the world around, (ii) choosing to be a doer and (iii) being in the here and now. We understood the children’s lived experiences of coping with stress as them being relaxed and powerful. The children chose to be active doers or inactive beings and their relationships, as well as their surroundings, helped or hindered their coping. Possible health promotion work is discussed.     

Young,successful, precarious? Precariousness at the entry stage of employment careers in Germany

ABSTRACT

The article investigates entry-stage employment trajectories of young people in Germany, asking whether transitions into continuous employment indicate successful labour market integration. Applying a novel multidimensional approach to precariousness to individuals’ employment and household trajectories, we understand entry-stage employment trajectories holistically. The balanced-panel sample is drawn from the German Socio-Economic Panel, with a focus on young men and women between 15 and 25 years of age in the first year of the sample period who had been employed at least once (n?=?1360).

Dual-channel sequence-cluster analysis reveals considerable variation in the precariousness of young people’s entry-stage employment. While almost all young men and women experience periods of precariousness, the durations vary substantially. Precarious employment or precarious living conditions frequently occur during education. Our results confirm that individuals with disrupted employment trajectories are seldom successfully integrated into the labour market and frequently experience precarious employment. In previous research, transitions into continuous employment have been understood as the hallmark of successful labour market integration. This holds true for young women but not for young men, who experienced continuous and precarious entry-stage employment. To correctly identify young men’s successful labour market integration, additional information about their employment precariousness is required.     

Moral Reflexivity and Dramaturgical Action in Social Movement Activism: The Case of the Plowshares and Animal Rights Sweden

Drawing on Durkheim's sociology of morality, which identifies ideals and norms as the key components of morality, this article outlines a theoretical model for understanding how social movements can bring about legitimate social change. Social movement activists, we propose, can be conceptualized as followers and pursuers of sacred ideals. As such, they frequently come into conflict with existing norms in society. To manage this dilemma, activists must downplay their role as norm breakers while emphasizing their identity as followers of ideals. This in turn requires moral reflexivity in the staging of collective action. The article shows how dramaturgical control (Goffman) is exercised towards this end among activists engaged in two social movements in Sweden: the Plowshares peace movement and Animal Rights Sweden. The article further examines the internal stratification, or ‘moral hierarchies’, within the two activist groups in the light of the proposed model. The closer the activists were able to adhere to the sacred ideal, the higher the social status they enjoyed within the group.     

Human Security Perspectives on Refugee Children in Germany

This research identifies challenges and solutions for the situation of accompanied children in German refugee accommodations along the seven human security dimensions (economy, environment, food, health, personal, community and political rights). It analyses existing binding and non‐binding standards for the protection of refugee children at federal, state and municipal level, and their development since 2014. In particular, the United Nations Children's Fund's role for the development of voluntary protection standards is discussed as a role model to enhance the awareness for the protection of refugee children in Germany.     

A Field of Contention: Evidence from Housing Struggles in Bucharest and Budapest

The article offers a study of housing movements in Budapest and Bucharest, with the main focus on the developments since the financial crisis of 2008, stressing the role that both structural and contingent factors play in shaping the dynamics of this “field of contention.” It is argued that a structural view is enlightening for understanding the factors that form the interactive field between activists, such as differences in social positionality as well as ideological conflicts. Moreover, conceiving of a structurally produced field of contention can help explain the differences in housing contention in the two cities. The analysis situates housing movements and their allied, parallel, or opposing actors within the long-term processes of urbanization and global dynamics of commodification, including housing financialization. It demonstrates that to understand how structural and political factors interact in a complex field of contention, attention to processes beyond short-term local movements is necessary.     

Self-deception in public relations. A psychological and sociological approach to the challenge of conflicting expectations

The paper enquires into the role of self-deception in public relations struggling with discrepancies between heterogeneous stakeholder expectations and organizational interests and particularly between normative expectations of truthfulness and practical temptations of deception. Drawing on theoretical foundations of evolutionary psychology and sociology, we propose a framework for the origins, drivers, and functions of self-deception in public relations. The analysis reveals that under specific conditions self-deception can be an essential mechanism in public relations because it relieves practitioners from tensions driven by conflicting perceptions of truth and legitimacy. Self-deception is most likely to occur in situations of cognitive dissonance for practitioners to balance internal information processing and in situations of normative pressure when practitioners seek to comply with external expectations.     

The new privatized market: A question of ideology or pragmatism within the Swedish addiction treatment system?

Given its traditions of universal welfarism and social democracy, Sweden had already scored unexpectedly high on New Public Management by the 1980s. Health and welfare services remain primarily tax‐funded, but the production of care is increasingly transferred to a competitive quasi‐market. To what extent can this development be understood in terms of right‐wing governments, and to what extent in terms of other, socioeconomic and pragmatic factors? We examined this question through official statistics on providers of institutional addiction care since 1976, and through the total expenditure and purchases by local‐level municipal social services of interventions for substance users in Sweden in 1999, 2004, 2009, and 2014. We have analyzed the distribution across public and private providers within the addiction treatment system, and whether national developments and local differences across the 290 municipalities—which bear the major treatment responsibility—can be understood in terms of local‐level political majority, population size, and local wealth. The share of purchased services has remained stable, but the treatment system shows increasing financial turnover and an increasing share of for‐profit providers among producers of purchased care, especially in outpatient treatment. While venture capital enterprises emerged as a new actor, non‐governmental organizations lost out in importance. Bourgeois government correlated with larger shares of purchasing and purchases from for‐profit providers. However, purchasing on a market dominated by for‐profit providers has also become the “new normal”, regardless of ideology, and recent years have shown a reversed effect of left‐wing municipalities purchasing more services than right‐wing governments. Pragmatic reasons also influence local‐level purchasing.     

Mental preparation during pregnancy in women with substance addiction: a qualitative interview‐study

The interplay between pregnancy and addiction is usually studied quantitatively, and the focus is often on the adverse effects of intrauterine substance exposure. This study explores the perspective of the mothers‐to‐be by examining the subjective experience of pregnancy in substance‐addicted women. Fourteen women in family treatment for substance use disorder participated in eight focus groups. The data were analysed according to interpretative phenomenological analysis. The findings show that recognition of pregnancy was distorted and delayed, and strong feelings of ambivalence and guilt persisted throughout pregnancy, along with hope for change. Addiction and an intense preoccupation with external expectations are seen as a threat to intrauterine attachment and mental preparation for the caregiving role. Interventions must take into account the specific ways in which addiction influences the psychological processes of pregnancy; specifically, providing adequate social support and security should be considered.
