Public pensions in transition

The main purpose of this paper is to analyze problems of financing an old-age insurance when birth rates are low and population declines or fertility fluctuates with time. A government then searches for optimal policies to cope with such problems. A first criterion could be seen in the Pareto principle. But we all know that there is no way out of PAYG unless at least one generation has to pay for the transition. Therefore an optimal policy is concerned with intergenerational redistribution and optimal growth.In the absence of public pensions the economy will in the long run converge to a steady state which is not optimal in the sense of a golden rule. This dynamic in-efficiency results from the decentralized decision making by the consumers and the firms. If the PAYG system influences the savings ratio of the economy, public pensions can be seen as an instrument to implement a modified golden rule.Paper presented at the ISPE-conference on The Fiscal Implications of an Ageing Population, Vaalsbroek, The Netherlands, May 30–June 1, 1990.

The Determinants of Trust and Credibility in Environmental Risk Communication: An Empirical Study

This study examines a key component of environmental risk communication; trust and credibility. The study was conducted in two parts. In the first part, six hypotheses regarding the perceptions and determinants of trust and credibility were tested against survey data. The hypotheses were supported by the data. The most important hypothesis was that perceptions of trust and credibility are dependent on three factors: perceptions of knowledge and expertise; perceptions of openness and honesty; and perceptions of concern and care. In the second part, models were constructed with perceptions of trust and credibility as the dependent variable. The goal was to examine the data for findings with direct policy implications. One such finding was that defying a negative stereotype is key to improving perceptions of trust and credibility.     

Information Technology in Public Services: Towards the Contractual Organization?

The growing trend towards information technology (IT) outsourcing is analysed within the UK public sector. The paper first details the research findings on factors influencing the degree of success experienced in a range of IT outsourcing deals. These factors are then utilized as a framework for analysing and discussing two case histories—of selective and large-scale IT outsourcing—drawn from different parts of the public sector. Both demonstrate how distinctive public-sector contexts influence the direction and degree of outsourcing. At the same time they highlight a range of managerial and organizational issues raised by moves towards contractual, core competence forms of organizing. Selective outsourcing is revealed as effective provided key decisions and actions are taken. The large-scale outsourcing case raises a number of critical issues not just for how it can be conducted in public-sector contexts, but also about the efficacy of such arrangements in terms of cost savings, possible over-dependence on a few suppliers, and ability to respond flexibly to changing political requirements and legislation.

From ‘not a big deal’ to ‘hellish’: Experiences of older people with dementia

Research on subjective experiences of dementia has paid scant attention to social location, due to fairly homogeneous samples and an inattention to socio-cultural diversity in data analysis. This article addresses this gap by presenting findings from a grounded theory study of the relationships between the experiences of older people with dementia and the intersections of ‘race’, ethnicity, class, and gender. Data generation occurred through a series of interviews, participant observation sessions, and focus groups with eight older people with dementia whose social locations varied from multiply marginalized to multiply privileged plus over 50 members of their social worlds. Their experiences of dementia were found to be varied, ranging from ‘not a big deal’ to ‘a nuisance’ to ‘hellish’, and to be related to their social locations. Negative views of life with dementia were not nearly as universal as past literature suggests and social location was found to mediate experiences of dementia.     

An F-type test for detecting departure from monotonicity in a functional linear model

When studying associations between a functional covariate and scalar response using a functional linear model (FLM), scientific knowledge may indicate possible monotonicity of the unknown parameter curve. In this context, we propose an F-type test of monotonicity, based on a full versus reduced nested model structure, where the reduced model with monotonically constrained parameter curve is nested within an unconstrained FLM. For estimation under the unconstrained FLM, we consider two approaches: penalised least-squares and linear mixed model effects estimation. We use a smooth then monotonise approach to estimate the reduced model, within the null space of monotone parameter curves. A bootstrap procedure is used to simulate the null distribution of the test statistic. We present a simulation study of the power of the proposed test, and illustrate the test using data from a head and neck cancer study.     

The changing practice of eating: evidence from UK time diaries, 1975 and 2000

This paper examines some central themes about change in consumption behaviour through an empirical investigation of the practice of eating. It analyses patterns of food consumption in the UK using time diary data from 1975 and 2000. The practice of eating is decomposed into four component activities which are used to explore systematically the inter-relationships between social processes - such as commodification and temporal fragmentation - and ways of providing and consuming food. It charts the expansion of eating out, the degree to which it substitutes for other eating activities, and the implications of its development for social relations and the temporal organization of daily life. Analysis reveals that food consumption continues to be differentiated along established lines of social division, although the content of those divisions has changed and varies across components of the practice. Increasing commodification of the food chain is documented, but without appearing to have a corrosive impact on household organization or social relationships. While tendencies indicative of temporal fragmentation are revealed, counter-tendencies exist which suggest that the practice of eating is resilient to many forms of external pressure. Finally, the application of a practice-based analytical approach permits critical evaluation of theories of social transformation.     

Emotional Regulation and Display in Classroom Victims of Bullying: Characteristic Expressions of Affect, Coping Styles and Relevant Contextual Factors

Research suggests that victims of bullying may lack skills in emotional regulation, a process which facilitates coping with provocative situations to lessen the stress of negative emotions (Cicchetti, Ackerman, & Izard, 1995). The present study examined the emotional regulation and display patterns of victims during classroom bullying episodes. Children in grades one through six were observed during free play in the winter and spring of three consecutive school years. Results of the study indicated that the coping styles observed in victims of bullying can be grouped into two distinct clusters: 1) problem-solving strategies that are associated with the de-escalation and resolution of bullying episodes; and 2) aggressive strategies that tend to perpetuate and escalate the bullying interaction. Parallels were found between victims' and bullies' emotional displays. Results are discussed in the context of how maladaptive emotional regulation processes may act as risk factors for chronic victimization.     

Use of Experiential Learning,Reflective Writing,and Metacognition to Develop Cultural Humility Among Undergraduate Students

This study discusses the use of experiential learning, reflective writing, and metacognition to develop cultural humility among undergraduate students enrolled in a social and economic justice course. Students participated in an activity that challenged them to learn about people who may have different social identities and experiences from their own such as attending a service in a religion different from their own. Then students wrote a reflective essay in which they used the margin of the paper as a safe space to write anything that came to mind during the writing process. A thematic analysis of students’ comments suggests that students used the space to examine their emotions, seek understanding of self and others, and recognize their privilege.
