Prospects for Examining Perceived Choice and Control Among Older Adults Living With Family

This review aims to advance the field of aging research by examining coresidence with family, race, and other characteristics as potential determinants of choice and control in older adults. Living with family likely impacts perceived choice and control, as household members often work together to make decisions about care. Race may also influence choice and control, as an accumulation of challenges and opportunities create unique life experiences. This review considers human agency in its examination of choice and control. Suggestions for future research will be discussed.     

USING CONJOINT ANALYSIS TO PREDICT TRIAL AND REPEAT-PURCHASE PATTERNS OF NEW FREQUENTLY PURCHASED PRODUCTS*

A new approach is proposed to evaluate new-product opportunities. This approach uses the distribution of brand-purchase probability of the new product over a population of potential customers and the outputs from conjoint analysis. The heterogeneous distribution of brand-purchase probability is expressed by a beta binomial brand-choice model compounded with a negative binomial product-class purchase-incidence model. The resulting model provides a way to predict trial and repeat-purchase patterns of new-product concepts. The paper discusses the development of the model. It also discusses issues of measurement, estimation, testing, and implementation of the proposed approach based on actual empirical data.     

Competence and consent to research: A critique of the recommendations of the national bioethics advisory commission*

Concern about the participation of incompetent subjects in psychiatric research has grown in the last several years. In response, the National Bioethics Advisory Commission (NBAC) recommended in its recent report that all investigations involving persons with mental disorders that may be associated with cognitive impairment that may pose greater than minimal risk to subjects utilize independent assessors to verify the capacities of subjects prior to entry into the study. This recommendation poses several problems for the conduct of research and the protection of research subjects. First, it fails to target that group of subjects most likely to be at risk for incapacity. Second, it focuses on too broad a range of research projects, many of which pose little risk to participants. The substantial costs of this approach are therefore not likely to be outweighed by concomitant benefits. In place of the NBAC recommendation, the author proposes a more flexible system of capacity assessment, designed to balance the costs with a greater likelihood of achieving meaningful protection for research subjects with mental disorders.     

Visions in monochrome: families, marriage and the individualization thesis

This paper takes issue with the way in which the individualization thesis--in which it is assumed that close relationships have become tenuous and fragile--has become so dominant in 'new' sociological theorizing about family life. Although others have criticized this thesis, in this paper the main criticism derives from empirical research findings carried out with members of transnational families living in Britain whose values and practices do not fit easily with ideas of individualization. It is argued that we need a much more complex and less linear notion of how families change across generations and in time.

Smallholder Preferences for Agri‐environmental Change at the Bhoj Wetland,India

Incentive‐based approaches have gained policy interest in linking change in agricultural land management with environmental conservation. This article investigates how scheme design influences smallholder farmers' decisions to switch to organic farming to reduce water pollution, drawing on a study at a Ramsar wetland site providing water for the city of Bhopal. Results from a choice experiment suggest that transitional payments are necessary to overcome farmer constraints to adopt organic farming, and that effective land certification has the potential to act as a self‐enforcing mechanism linking farmer incomes with wetland conservation benefits.

A Faith‐Based Advantage?

This study explored whether religiously affiliated nonprofit schools participating in Milwaukee's long‐standing school voucher program engage in more fundraising and perform better on academic indicators than nonsectarian nonprofit schools. The analysis of three years of organizational‐level voucher school data reveals that a higher percentage of religious affiliated schools engage in fundraising, and that religious schools affiliated with umbrella organizations have higher test score indicators than nonsectarian schools. The author concludes that the religious advantage is likely in part a result of the broader access to networks and resources available to religious schools associated with umbrella organizations like a Catholic archdiocese or Lutheran synod. The results are relevant to policymakers who are considering implementing a reinvented government approach to the provision of public goods, as well as leaders of nonprofit corporations who seek to maximize performance.
