Tests on asymmetry for ordered categorical variables

Skewness is a well-established statistical concept for continuous and, to a lesser extent, for discrete quantitative statistical variables. However, for ordered categorical variables, limited literature concerning skewness exists, although this type of variables is common for behavioral, educational, and social sciences. Suitable measures of skewness for ordered categorical variables have to be invariant with respect to the group of strictly increasing, continuous transformations. Therefore, they have to depend on the corresponding maximal-invariants. Based on these maximal-invariants, we propose a new class of skewness functionals, show that members of this class preserve a suitable ordering of skewness and derive the asymptotic distribution of the corresponding skewness statistic. Finally, we show the good power behavior of the corresponding skewness tests and illustrate these tests by applying real data examples.     

Chile and beyond: The second-generation pension reforms in Latin America

In the early 1990s, pension reforms leading to substantial changes in the organization and financing of old age security were undertaken in Argentina, Colombia and Peru. Implemented ten years after the pioneer reforms in Chile, they have taken advantage of the experiences and lessons of the Chilean case; at the same time, the second-generation reforms clearly demonstrate the restrictions policy makers are being faced with in a democratic political context. This paper examines the recent pension reform experiences in Latin America and discusses their implications for a modified concept of old age security.     

The Speed of Experience: The Co‐narrative Method in Experience Economy Education

This paper proposes a management learning technique called the co‐narrative method. This approach is seen as a useful means of capturing the subtler nuances of experience economy interactions, as well as learning ethics and corporate social responsibility, by nurturing empathy and compassion. A method is presented based on the example of the idea of slow as fast side of organizational and festival experiences, which is explored through autoethnographic studies of participation in experience economy events. It builds upon insights into improving management education through the use of the humanistic approach. The so‐called co‐narrative method is based on a syzygic mode uniting the two oppositions (while preserving their inherent contradictions). It encourages its users to exercise understanding of the experience of the Other, while teaching about concrete cases and events.     

The eIFL.net Initiative: Access and Management of Electronic Resources by Library Consortia in Developing and Transition Countries

Abstract

eIFL.net is an umbrella organization of library consortia in fifty transition and developing countries. Its main purpose is to negotiate, encourage, and advocate for the wide availability of scholarly electronic information by library users from the education and research sectors, professional communities, governmental organizations, and civil society.

The paper presents the beginnings, goals, and development of eIFL.net in its five years of existence. The authors outline what it has achieved so far and provide an overview of the main challenges that developing countries face in accessing quality e-resources. Some success stories will demonstrate concrete accomplishments of the organization and its participating countries.     

Regulation and supervision of pension funds: Principles and practices

This paper examines the current principles and practices of pension fund regulation and supervision around the world. First an overview of the main approaches in OECD and non-OECD countries and the most important issues and their relevance for different types of pension plans will be given. Then the paper will focus on a selection of issues which are the subject of intense debate at the moment, particularly in the Latin American context: the imposition of quantitative restrictions on pension fund investments, state guarantees for private pensions, and fee and cost controls.     

Speech Perception by 6‐to 8‐Month‐Olds in the Presence of Distracting Sounds

The role of selective attention in infant phonetic perception was examined using a distraction masker paradigm. We compared perception of /bu/ versus /gu/ in 6‐ to 8‐month‐olds using a visual fixation procedure. Infants were habituated to multiple natural productions of 1 syllable type and then presented 4 test trials (old‐new‐old‐new). Perception of the new syllable (indexed as novelty preference) was compared across 3 groups: habituated and tested on syllables in quiet (Group 1), habituated and tested on syllables mixed with a nonspeech signal (Group 2), and habituated with syllables mixed with a non‐speech signal and tested on syllables in quiet (Group 3). In Groups 2 and 3, each syllable was mixed with a segment spliced from a recording of bird and cricket songs. This nonspeech signal has no overlapping frequencies with the syllable; it is not expected to alter the sensory structure or perceptual coherence of the syllable. Perception was negatively affected by the presence of the auditory distracter during habituation; individual performance levels also varied more in these groups. The findings show that perceiving speech in the presence of irrelevant sounds poses a cognitive challenge for young infants. We conclude that selective attention is an important skill that supports speech perception in infants; the significance of this skill for language learning during infancy deserves investigation.     

Struktur und Identität des Nicht-Religiösen: Relationen und soziale Normierungen

With reference to recent research, the article outlines central elements of a sociological analysis of the non-religious. Starting with a definition of the non-religious via its relation towards the religious, we distinguish different forms of this relation and three levels of its analysis. Then we analyze two different societal constellations: a strong religious norm in the US, and a strong non-religious norm in the GDR. We show how an arena of conflicts emerges in the debates over religion, in which religious and non-religious positions struggle for dominance. We analyze different variations of non-religious positions in this context. In both constellations the non-religious position acquires a positive identity by reference to science. In one case this is motivated by the attempt to maintain the borders of the scientific field; in the second case it is motivated by a claim of superiority, which questions the legitimacy of the religious in general.     

The perceived fair duration of unemployment benefits for older workers. The role of lifetime achievements in the labour market

The welfare state regulates social policies and reallocates scarce resources. For the social legitimacy of the welfare state, it is important that the public supports the principles underlying this reallocation. This article examines the impact of different activities during the life course on public deservingness perceptions of older unemployed people. In a factorial survey experiment conducted among a random sample of individuals drawn from German administrative employment records, we examine the maximum duration of benefit receipt which is perceived as fair for older unemployed persons with different biographies. The results indicate strong public support for a nexus between previous contributions and benefit entitlements. Besides financial contributions to unemployment insurance, parenting and further training are considered to be ‘lifetime achievements’ which justify longer unemployment benefit receipt. We interpret these findings as an expression of a generalised form of reciprocity which guides perceptions of deservingness regarding older unemployed persons.     

Battling parenting: The consequences of secure care interventions on parents

Secure care in Sweden is the most intrusive child welfare intervention, and children and their family members have restricted contact. For each child in secure care, there are at least twice as many affected family members and parents who must manage the consequences of this institutionalization. Clearly, it is just as important to understand how secure care affects parents as it is to understand how secure care affects children. To address this issue, we conducted in-depth interviews with 11 parents to eight children who had been placed in secure care during their childhood, focusing on the institutional and societal structures that affected these parents and their parenting. With a narrative approach, stories alluding to a metaphor of war are identified. These stories reveal how all parents (but especially single mothers) are affected by their diverse socio-economic positions and the rigid frames of family life presumed by child welfare interventions. In these narratives, parenting emerges as a social practice rather than a skill. Above all, the stories demonstrate a great deal of vulnerability and sensitivity of parenting. The findings raise critical questions about the meaning and overarching consequences of institutional interventions in a family life.     

Improvisation and Innovation in Teams: The Jazz Effect

While numerous models examine the linkages between improvisation and innovation, the factors that moderate this relationship at the team level are unknown. Consequently, this study builds on principles and insights from the jazz jam session framework used by jazz musicians and regression analysis to examine the nature of the improvisation process and consider how it affects innovation. By using unbalanced panel data on 2,749 teams containing between two and eight employees in the United Kingdom during 2002–2016, this study demonstrates that the success of the improvisation process relies on both internal and external factors conducive to innovation. Subsequently, the conclusions drawn may help entrepreneurs and team managers think differently about the role improvisation plays in the innovation activity. As a result, important practical implications are drawn for team managers and entrepreneurs intending to cultivate a willingness to improvise in teams and nurture collaborative relationships with external partners for innovation.
