The Other Side of Ownership in Nonprofit Organizations: an Economic Rationale for Democracy

Going beyond the deeply examined non-distribution constraint, which refers to the right to residual income, the paper investigates the other side of ownership, i.e. the right to residual control, to discover a general economic rationale for what we call “democracy”: a collective decision-making method based on the principles of equality and inclusiveness. The main result of the analysis is to point to the concept of perfect democracy as an efficient solution for the provision of public goods where other allocative mechanisms, such as the marketplace, fail.     

Censored Exponential Data: Large Deviations for MLEs and Posterior Distributions

In this article, we consider several statistical models for censored exponential data. We prove a large deviation result for the maximum likelihood estimators (MLEs) of each model, and a unique result for the posterior distributions which works well for all the cases. Finally, comparing the large deviation rate functions for MLEs and posterior distributions, we show that a typical feature fails for one model; moreover, we illustrate the relation between this fact and a well-known result for curved exponential models.

The unusual genetics of human longevity

In no species other than humans do cultural, social, and biological factors interact with each other in modulating complex phenotypes. Thus, the identification of genetic factors that affect human longevity is a true challenge. The model of centenarians provides us a unique opportunity to tackle this challenge. In this Perspective, we discuss some recent findings (the impact of geography and demography on the longevity phenotype, the relationship between longevity and homozygosity, the role of the nuclear-mitochondrial genome cross-talk) by which new ideas are suggested, such as the concept of a complex allele timing as a pivotal process in modulating the probability of achieving longevity.     

Well-Being and Affective Commitment among Ambulance Volunteers: A Mediational Model of Job Burnout

ABSTRACT

Burnout represents a relevant risk for ambulance volunteers. According to the Job Demands-Resources model, role conflict and social support can be considered as antecedents of burnout which, in turn, may lower affective commitment. This study aims to investigate the relationship between social support, role conflict, and affective commitment, as mediated by job burnout. Survey data were collected from 352 Italian volunteers and analyzed using structural equation modeling methods. Social support was confirmed as a protective factor, and role conflict as an antecedent of burnout which, in turn, decreases affective commitment. The relationship between role conflict and affective commitment is mediated by burnout which, on the contrary, does not mediate the effect of social support on affective commitment. Social support may protect against burnout. Because of its positive effects on a personal and an organizational level, affective commitment may be increased raising levels of supervisor support and reshaping role expectations. It could be useful to carry out future longitudinal studies, in order to confirm the antecedents and effects of job burnout; furthermore, this research should be extended to other ambulance organizations, in order to generalize the results; finally, multi-group analyses would allow to bring out possible differences between paid-staff and volunteers.     

Priority Topics in the Study of Environmental Risk in Developing Countries: Report on a Workshop Held at the East–West Center, August, 1988

The rapid industrialization occurring in developing regions of the world brings not only economic benefits, but changes in the types and severity of health and environmental problems that each region experiences. As the industrialized world moves toward the use of risk assessment methodologies to aid in problem evaluation and regulatory and policy decision analysis, it seems inevitable that these methodologies will be applied globally. The changes brought about by rapid industrialization, however, must be viewed within the context of societies that are still struggling with the more traditional and basic environmental problems associated with urban and rural poverty. The urgency of development and the lack of adequate resources for characterizing health and environmental changes, often present under these circumstances, offer special challenges to the application of risk assessment methodologies.     

Local depth

Local depth is a generalization of ordinary depth able to reveal local features of the probability distribution. Liu's simplicial depth is primarily used, but results for Tukey's halfspace depth are also derived. It is shown that the maximizers of local depth can help to detect the mode(s) of a probability distribution. This work is devoted to the univariate case, but the main definitions are stated in the general multivariate case. Theoretical results and applications are illustrated with several examples.     

Maculate Conceptions: Power,Process, and Creativity in Participatory Research

Justifiably concerned about power dynamics between researchers and participants in participatory research, much of the literature proposes guidelines for including participant voices at every step of the research process. We find these guidelines insufficient for dealing with constraints set up by the social organizational structures in which researchers and participants find themselves. We argue that the process of building relationships between scientists and farmers is unavoidably imperfect, but nonetheless necessary and rewarding. We contend that the potential problems of participatory research originate more from the social organizational structures in which it takes place than in failure to follow particular rules. By acknowledging these structures and the resultant interests of participant and researcher we can make room for the messy reality of negotiating participatory relationships. We suggest that transformative engagement can be born of what we term the “maculate conceptions” of dialogic process and the building of mutual trust.     

关掉电灯——合理使用照明

2003年8月的一个下午,包括百老汇在内的美国东北部、中西部城市以及加拿大安大略省经历了一次大停电,约5千万人受到这次停电事故的影响。除了抱怨不方便、公交乘客一筹莫展、以及饭店和市场里的食品腐败变质之外,许多城市居民感到震撼的是,当夜幕降临时,透过黑暗的摩天大楼,人们凝望天空,看到了令人惊讶的景象——璀璨星空。这些居住在东北部电力发达城市的居民自发聚集,凝望星空这一幕被《纽约时报》报道。     

Adolescent Self‐cutting: An Embodiment of the Unsaid

This paper describes adolescent self‐cutting from a systemic–relational standpoint utilising two key concepts: embodied mind and the unsaid. Varella's notion of embodiment is introduced to understand the body as a field of meaning and the unsaid is conceptualised as what holds ‘said meaning’ and gives a sense of identity. These ideas are illustrated by reflections on a clinical vignette.
