AIM:To examine and compare the effects of subjective and objective social isolation on behavioral health in elderly adults.
METHODS:A systematic search of PubMed was performed for original research articles from peerreviewed journals examining one of the following topics: "Social isolation and sleep disturbance", "social isolation and depression", or "social isolation and fatigue in older adults". Studies were selected following the criteria established based on the aim of this review. Data were extracted from the articles by two independent reviewers. Due to the heterogeneity in study designs and outcome measures of the included studies, qualitative and narrative analyses were conducted.
RESULTS:The set criteria were used to select a total of 16 studies for the review. Of the 16, 13 were crosssectional studies. The characteristics of study populations were identified as follows. A total of 12 studies randomly selected subjects irrespective of pre-existing health conditions. Consequently, an unspecified number of the study subjects had chronic diseases in the studies compared. In addition, cultural and ethnic backgrounds of studies in this review were diverse, and included subjects living in North America, South America, Asia, Europe, and Oceania. Both subjective and objective types of social isolation increased behavioral symptoms, such as sleep disturbance, depressive symptoms, and fatigue in older adults. Furthermore, a few recent studies reported stronger effects of subjective social isolation than objective social isolation on sleep disturbance and depressive symptoms.
CONCLUSION: Social isolation affects behavioral

As a growing number of customers tend to view corporate social responsibility (CSR) as a key purchase decision criterion, demands for CSR including environmental sustainability have accelerated in today's business world. To meet such demands, many firms consider embracing environment-friendly business practices. However, many firms are still hesitant to implement those practices due to sceptical views about their real managerial benefits. Although the previous literature confirms the positive link between a firm's commitment to environmental sustainability and its performance, the varying degree of impact of different kinds of environment-friendly supply chain practices on the firm's operational performance is still unknown. To fill the void left by prior research, this paper aims to classify various types of green supply chain management (GSCM) practices and then assess the impact of each of these distinct types on the firm's operational performances (especially manufacturing and marketing performance). Also, this paper examines how the firm's organisational profiles such as firm size affect the particular firm's choice of GSCM practices. Our experimental results reveal that the chosen type of GSCM practices influences the firm's performance differently.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
