Multimedia Biographies: A Reminiscence and Social Stimulus Tool for Persons with Cognitive Impairment

The multimedia biography tells the story of the life of an elderly person with a cognitive impairment in motion picture format. The multimedia biography combines family photographs, film clips, audio narration, and music. It is intended to be screened on an ongoing basis to provide spaces for reminiscence and communication between cognitively impaired persons and their families. Using a production process in which we collaborated with family caregivers, we created 12 multimedia biographies for persons having Alzheimer's disease or mild cognitive impairment. This article describes our production and screening processes. We also share lessons learned from the multimedia biography research to assist practitioners, families, or researchers who wish to use similar technologies and processes for eliciting and sharing life stories.     

The Role of Appraisal and Expressive Support in Mediating Strain and Gain in Hispanic Alzheimer's Disease Caregivers

Abstract

The purpose of this study was to examine how appraisal of burden and satisfaction, and perception of expressive support mediate the effects of caregiving on depression, somatic complaints, life satisfaction and personal gain with a sample of Hispanic Alzheimer's disease (AD) primary caregivers. A purposive-snowball sampling technique was used to identify 103 Hispanic caregivers, who completed a self-report questionnaire. A translation-back-translation process was used to translate the instruments into Spanish. Translated instruments were then pilot tested prior to being administered to the participants. Appraisal of burden was found to mediate the effects of caregiving on depression and somatic complaints and had significant direct effects on life satisfaction. Appraisal of satisfaction did not have a mediating effect on any of the measures, but did have a direct effect on depression and personal gain. Expressive support did have a mediating effect on depression, as well as direct effects on somatic complaints and life satisfaction. These findings suggest a need for improving outreach to older minorities and developing culturally sensitive interventions that can improve caregivers' understanding of problematic behavior, thereby altering appraisal of the situation, as well as developing extended systems of support.     

新型城镇化与经济转型:反思与借鉴

目前,我国已开始步入工业化中期阶段,城镇化也迈入了从传统城镇化向新型城镇化转变的关键时期。城镇化发展具有一般规律性,即阶段性、要素集聚与扩散以及经济发展水平决定规律。我国城镇化发展过程中伴随的是掠夺式扩张和线性发展模式,土地和政府助推了城镇化的粗放发展模式。因此,对我国现阶段新型城镇化过程进行反思,并借鉴国外城镇化的成功经验,创新城镇化发展战略与路径模式,对于推进我国现代化、实现富民强国具有重大现实意义。     

Tracking Transformations in Health Movement Organisations: Alzheimer's Disease Organisations and their Changing ‘Cause Regimes’

In this paper, we aim to contribute to the elaboration of a framework for the systematic periodisation of health social movement organisations (HSMOs). Drawing on historical and contemporaneous data on two organisations that identify as Alzheimer's disease movement organisations (the Alzheimer's Society in Britain and the Alzheimer Society of Ireland), we consider transformations in these organisations' ‘cause regimes’. By cause regime, we refer to who and what an HSMO is fighting for, as articulated in its public self-identifications; to the broader framing of the cause and to how organisations' public self-identifications of their cause can govern or regulate their operation, including their interactions with and representations of those on whose behalf they advocate. We show that the transformation of HSMOs' cause regime can give rise to a series of organisational tensions and challenges, including the alignment of the public identification of its cause with the patient identities it promotes, or its day-to-day ‘patient identity work’.     

Eight Years of Data on Residents in Small Dementia-Care Settings Suggest Functional Performance Is Maintained

Eight years of data analysis on residents’ status from three small Alzheimer care centers suggest notable stability in function. Individuals’ functional ability was best in their first year, but their year-to-year decline was mostly not significant. Cognitive abilities also were best in the resident's first year, but first-, second-, and third-year cognitive scores were not significantly different. We compared the residents’ dementia progression rate to the true rate of natural disease progression. This study, like others on small homelike settings, suggests that appropriate homelike environments maintain persons with dementia at an optimum level longer.     

Entry into Consensual Unions and Marriages Among Finnish Women Born Between 1938 and 1967

This study, based on a survey undertaken in 1989, clearly illustrates the dramatic changes in family formation behaviour that have occurred in Finland. Whereas only about one-tenth of the first unions of women born between 1938 and 1942 began as consensual unions, after the cohort of 1962 only one-tenth were formal marriages. These changes lagged some ten years behind the corresponding ones in Sweden, but were about five years ahead of Norway. In Finland, up to the present, most consensual unions have constituted a temporary state which precedes proper family life. Most couples married in connection with the birth of the first child. Consensual union as a permanent lifestyle is generally connected with a low level of education of women.     

The Do-It-Yourself (DIY) Movement and Young People with Serious Physical Illnesses Who Support Building Communities of Care

In 2011–2012, a qualitative exploratory pilot study was conducted to examine the experiences of immigrant Mexican women using a culturally specific domestic violence intervention model curriculum in a Midwestern state. Using a psychoeducational group format, 20 immigrant Mexican women participated in two 11-week groups over a 9-month period at a community-based health clinic. Findings indicated immigrant Mexican women examined current relationships, dating, and domestic violence dynamics in group settings and reported changes in self-esteem within their own culture. Implications for social workers include learning how they can use culturally competent curriculums and programs in group formats.     

The Probable Impact of Proposed Legislative and Budgetary Changes on the Lives of the Elderly and Their Families

The decade of the 1980s is characterized by economic uncertainty and political ambiguity regarding the direction of American public policy for the elderly. The purpose of this paper is to: (1) review demographic trends that particularly affect older adults; (2) summarize theReagan Administration's proposed cutbacks in programs and policies for the elderly; and (3) address the effects of these cuts on older individuals as well as on family systems across generations. It is our contention that the proposed budget cuts will seriously reduce a number of federal programs which have been developed to meet the needs of older adults. The impact of these cuts will be felt by all of the elderly and to a considerable extent, their families. However, the effects will be most severe for people who have poverty or near-poverty incomes, single women, and the "frail" elderly. The discussion suggests that these proposed budget cuts seem to reflect a lack of appreciation and recognition of both needs of the older individuals and those of their families. In addition, suggestions for program and policy directions, as well as further research are addressed.     

When Everyone Is an Orphan: Against Adopting a U.S.-Styled Orphan Drug Policy in Canada

Putting aside whether diseases that affect only small numbers of people (“rare diseases”) should be prioritized over diseases that are otherwise orphaned, in this article I argue that a new approach to rare, orphan diseases is needed. The current model, first signaled by the United States' Orphan Drug Act and subsequently emulated by several other jurisdictions, relies on a set of open-ended criteria and market-based incentives in order to define and encourage drug therapies for rare, orphan diseases. Given a) the biopharmaceutical industries' growing interest in orphan diseases, b) progress in the sphere of personalized medicines enabling more and more common diseases to be reclassified as rare, and c) empirical evidence suggesting that the most orphan drugs target only a limited, lucrative subset of rare diseases, I argue that Canada, which recently announced plans to develop its own “orphan drug framework” should not follow the United States' orphan drug model.
