Even Cycles and Perfect Matching Problems with Side Constraints

We study two different types of graphs that contain even cycles and, possibly, some chords. The objective is to analyze some properties of these types of graphs that can be used to solve perfect matching optimization problems with side constraints. In particular, we obtain the maximum number of edges of certain classes that can occur in the solutions to the considered problems. Finally, we apply the obtained results to derive a class of valid inequalities and a possible enumerative scheme.     

Health Status,Living Arrangements,and Service Use at 100: Findings From the Oporto Centenarian Study

ABSTRACT

This paper describes the sociodemographic characteristics, health status, and service use of centenarians living in the community and centenarians residing in an elder care facility/nursing home and examines their main differences. Participants were 140 centenarians from the population-based Oporto Centenarian Study (M_age = 101.2; SD = 1.6). Main findings revealed that the majority of the centenarians lived at home with their family members (57.9%). Increased health care needs, living alone, and family caregiving constraints were the most common reasons for entering a nursing home. Community-dwelling centenarians were cared for mostly by their children and were less dependent and in better cognitive health than those who resided in a nursing home. Differences were found in the pattern of health service use according to the centenarians’ residence, ability to pay medical expenses, and dependency level. Findings highlight the need for an accurate assessment of caregiving support systems, particularly family intergenerational duties, and of the factors constraining the access and use of health and social services. Policy makers may be guided by the insights gained from this research and work toward improvement of support options and removal of barriers to service access.     

A Data-Driven Approach to Construct Survey-Based Indicators by Means of Evolutionary Algorithms

Despite growing understanding of resilience as a process associated with both individual capacities and physical and relational resources located in social ecologies, most instruments designed to measure resilience overemphasize individual characteristics without adequately addressing the contextual resources that support resilience processes. Additionally, most resilience studies have focused on children and youth, without significant attention to social ecological factors that promote post-risk adaptation for adults and how this is measured. Consequently, a key issue in the continued study of adult resilience is measurement instrument development. This article details adaptation of the Child and Youth Resilience Measure for use with an adult population. The article draws on data from a mixed methods study exploring the resilience processes of Irish survivors of clerical institutional abuse. The sample included 105 adult survivors (aged 50–99) who completed the RRC-ARM and the Warwick–Edinburgh Mental Well-being Scale (WEMWBS) during the first phase of the study. Exploratory factor analysis, Cronbach Alpha and MANOVA were conducted on the data. EFA identified five factors; social/community inclusion, family attachment and supports, spirituality, national and cultural identity, and personal competencies. The RRC-ARM shows good internal reliability and convergent validity with the WEMWBS, with significant differences on scale scores for men and women, as well as place of residence. This exploratory adaptation supports the potential of the RRC-ARM as a measure of social ecological resilience resources for adult populations and may have particular applications with vulnerable communities. Further validation is required in other contexts and specifically with larger samples.     

Framing home-care policy: A case study of reforms in a Canadian jurisdiction

Much of the literature on home-care services reform—an issue in the spotlight of policy debate across many ‘aging’ industrialized countries—has focused on the organizational, financial and clinical aspects of service provision. Less attention, however, has been paid to how particular issues and reform alternatives gain momentum in a given context; in particular to how a selective range of policy initiatives reach government's agenda and get incorporated into mainstream policy-making. This article seeks to advance our understanding of home-care policy by considering the influence of ideational factors on reform undertakings. More specifically, while concentrating on home-care policies in the province of Quebec, Canada, it examines how the organized perspectives and differing concerns of various stakeholders—i.e. their policy frames—appear to have shaped the form and content of policy. It is argued that framing provides a cogent and insightful means of understanding policy change and stasis in this area, most notably why managed competition or an all-out privatization of service delivery, as seen in other jurisdictions, has not been advocated by government in Québec.     

Ethical tensions of migrants in the informal economy in the Global South

Considering the ongoing, record-setting migration in the Global South, this paper explores the values, principles and ethical tensions of Venezuelan migrants in the informal economy of Colombia. We found that migrants frequently prefer to stay within the informal economy as a way of preserving their identities, values and principles, rather than adopting those of their new country. This choice sets up ethical tensions for the migrants and their host countries. Our analysis challenges the current policy goals of transitioning migrants from informal to formal economies as a mark of success and inclusion. Instead, we attempt to recognize the migrant voice and their agency capacity through our research using focus groups and applied thematic analysis (ATA) of popular music and narratives. Our findings broaden the understanding of why migrants choose to stay in the informal economy and challenge policy goals that focus on inclusion and integration of migrants into formal economy.
