Abstract Objectives This study aimed to assess the relationship between social isolation and cognitive functioning. Methods Data were retrieved from the National Survey of the Japanese Elderly, a nationally representative sample of Japanese adults, aged 60 years or older. We estimated a social isolation index to incorporate variables, such as social interactions, social engagement, and social support, with perceived social isolation, for a comprehensive measurement. The association of social isolation with cognitive functioning was assessed using a panel data fixed-effects model, controlling for age, socioeconomic status, health-related variables, and time-invariant heterogeneity. Moreover, we conducted analyses using the System Generalised Method of Moments (GMM) to address the dynamic relationship of cognitive functioning and potential endogeneity. Results For both men and women, the association between social isolation and cognitive functioning was significant, particularly among those aged 75 or older, as a 1% increase in social isolation was associated with decreased cognitive functioning (24% decrease for men, and 20% decrease for women). However, this association was not confirmed by the System GMM, after addressing endogeneity. Discussion Our findings potentially suggest that the association between social relationship and cognitive functioning reported in previous studies was biased, due to endogeneity. Although we did not observe causal impacts, this does not necessarily mean that social isolation does not have a negative impact on health, as both positive and negative consequences of social relationships may exist. Further research is needed to reveal the causal relationship, as well as the detailed mechanisms of health effects of social relationships.

Abstract This research aimed to assess the relationship between social isolation and cognitive functioning among older Japanese adults, thereby expanding the relevant literature in two main ways. First, we estimated a social isolation score to incorporate objective measurements of social isolation into a subjective measurement. Second, a panel data analysis was utilised to consider the change in the social isolation score and time-invariant unobserved heterogeneity. Data were derived from the National Survey of the Japanese Elderly, a survey of a sample of older Japanese adults aged 60 to 99 in waves 3 through 7, which contain unified information of social isolation. The sample included 4,889 observations (1,836 individuals) for men and 6,621 observations (2,433 individuals) for women. The predicted isolation score was obtained by a random-effects ordered logistic regression (i.e., regressing a subjective feeling of isolation on variables regarding social interaction, social support, and social engagement). The association of cognitive functioning with the isolation score was estimated by a fixed-effects ordinary least squares regression, controlling for age, socioeconomic variables, health conditions, and time fixed-effects. We found that increased isolation was associated with a deterioration in cognitive functioning, both for men (coefficient: 0.66, robust standard error [SE]: 0.30) and women (coefficient: 0.90, SE: 0.26). Findings of this research highlight the importance of actions aimed at inhibiting social isolation for the prevention of cognitive decline. This approach is potentially beneficial for developing measurements of both subjective and objective social isolation and estimating the longitudinal relationship between social isolation and cognitive functioning.

Gerontological Nursing

The COVID-19 pandemic compelled states to limit free movement, in order to protect at-risk and more vulnerable groups, particularly older adults. Due to old age or debilitating chronic diseases, this group is also more vulnerable to loneliness (perceived discrepancy between actual and desired social relationships) and social isolation (feeling that one does not belong to society). This forced isolation has negative consequences for the health of older people, particularly their mental health. This is an especially challenging time for gerontological nursing, but it is also an opportunity for professionals to combat age stereotypes reinforced with COVID-19, to urge the measurement of loneliness and social isolation, and to rethink how to further adjust interventions in times of crisis, such as considering technology-mediated interventions in these uncertain times.

Abstract Background Perceived social isolation (SI), the subjective sense of feelings of loneliness or isolation, has a negative impact on health outcomes, particularly in older adults. Although SI may also contribute to poor prognosis in patients with HF, evidence on the relationship between SI and outcomes in patients with HF is limited. Purpose The aim of this study was to investigate the relationship between SI and hospital readmission in patients with HF. Methods This study was a single center prospective cohort study. We consecutively enrolled 203 patients (mean age 72.9±11.7) who admitted for acute HF or exacerbation of chronic HF. At hospital discharge, we assessed perceived SI by using Lubben Social Network Scale - 6 (LSNS-6). Lower scores in LSNS-6 represents greater SI. Study outcome was rehospitalization for worsening HF within 180 days after discharge. We selected the optimal cutoff point of LSNS-6 that predict a worse outcome by the receiver operating characteristic (ROC) curve analysis. We investigate the association between SI and 180-days HF rehospitalization by using Cox proportional-hazard models, controlling for potential confounding factors. Results During follow up, A total of 40events (19.7%) were observed. The optimal cut-off point of LSNS-6 score was 17 points (the area under the ROC curve: 0.62, p<0.05, sensitivity: 82.5%, specificity 42.4%). Kaplan-Meier survival curves showed that those patients with greater SI (LSNS-6≤17) presented significantly higher HF rehospitalization rate (Figure). After adjusting for several pre-existing prognostic factors, LSNS-6≤17 was independently associated with HF rehospitalization (hazard ratio2.15,95% confidence interval 1.00–4.89). Conclusion The present study shows that SI is a independent predictor of HF rehospitalization in patients with HF. Assessing SI in the clinical practice with a brief screening tool may help identify patients with heart failure at greater risk of rehospitalization.

This paper studied the behavior of management toward the implementation of Good Corporate Governance in Indonesia to determine whether it has any influence towards profitability and its implication to the Manufacturing Firms’ value publicly listed in Indonesian Stock Exchange. There were 41 corporations who met the criteria of the survey. The data were analyzed using Panel Regression with fixed effects Model. The empirical findings show that the implementation of Corporate Governance in Indonesia has a positive, significant and direct impact toward firms’ profitability and firms’ value. Corporate Governance principles based on OECD principles that have positive and significant impact to both profitability and Firms’ Valueis Rights of Shareholders, Role of Stakeholders, Responsibilities of the Board Commissioners and Board of Directors. The principles that have significance and negative impact towards corporate profitability and value, are: Equitable treatment of shareholders and Disclosure and Transparencies. The most significant principle influencing profitability and firms’ value is Disclosure and Transparencies. Profitability plays a greater role in influencing Manufacturing Firms’ value in Indonesia.

The Impact

With the increase in labor costs in China and the tremendous changes in the international trade environment, upgrading the total factor productivity of Chinese furniture export enterprises faces a great challenge. Lots of studies have explored the interaction of exports or misallocation on the total factor productivity (TFP) of furniture enterprises, however, there is little knowledge on the impact and interaction of both exports and misallocation on the TFP. Based on panel data of Chinese furniture enterprises, this paper measures the TFP and the distortion of labor and capital resources in Chinese furniture enterprises. A two-way fixed-effects model is used to analyze the impact of exports and misallocation on the TFP of Chinese furniture enterprises. The paper reveals several important findings. First, the TFP of Chinese furniture export enterprises is lower than that of non-export enterprises, this phenomenon is called the “export–productivity paradox”. Chinese furniture export enterprises are processing trade-oriented and labor-intensive enterprises at the low end of the value chain, exports have a negative effect on improving the TFP of furniture enterprises in the short term. Second, the distortion of labor and capital resources in Chinese furniture enterprises promotes improvements to the TFP of furniture enterprises rather than reducing the TFP of furniture enterprises. Last but not the least, we find that misallocation has a positive moderating effect on exports and can weaken the negative impact of exports on TFP by the “forced mechanism”, which is that the higher the distortion of the misallocation, the higher the cost of acquiring capital and labor, and enterprises are forced to enhance their productivity when facing market competition, thus promoting improvements to the TFP of furniture enterprises.

Perceived Social Isolation

AbstractThe SARS-CoV-2 pandemic placed many locations under ‘stay at home” orders and adults simultaneously underwent a form of social isolation that is unprecedented in the modern world. Perceived social isolation can have a significant effect on health and well-being. Further, one can live with others and still experience perceived social isolation. However, there is limited research on psychological well-being during a pandemic. In addition, much of the research is limited to older adult samples. This study examined the effects of perceived social isolation in adults across the age span. Specifically, this study documented the prevalence of social isolation during the COVID-19 pandemic as well as the various factors that contribute to individuals of all ages feeling more or less isolated while they are required to maintain physical distancing for an extended period of time. Survey data was collected from 309 adults who ranged in age from 18 to 84. The measure consisted of a 42 item survey from the Revised UCLA Loneliness Scale, Measures of Social Isolation (Zavaleta et al., 2017), and items specifically about the pandemic and demographics. Items included both Likert scale items and open-ended questions. A “snowball” data collection process was used to build the sample. While the entire sample reported at least some perceived social isolation, young adults reported the highest levels of isolation, χ2(2) = 27.36, p < 0.001. Perceived social isolation was associated with poor life satisfaction across all domains, as well as work-related stress, and lower trust of institutions. Higher levels of substance use as a coping strategy was also related to higher perceived social isolation. Respondents reporting higher levels of subjective personal risk for COVID-19 also reported higher perceived social isolation. The experience of perceived social isolation has significant negative consequences related to psychological well-being.

The Relationship

Grooming interactions benefit groomers, but may have negative consequences for bystanders. Grooming limits bystanders' grooming access and ensuing alliances could threaten the bystander's hierarchy rank or their previous investment in the groomers. To gain a competitive advantage, bystanders could intervene into a grooming bout to increase their own grooming access or to prevent the negative impact of others' grooming. We tested the impact of dominance rank and social relationships on grooming intervention likelihood and outcome in two sympatric primate species, Western chimpanzees ( Pan troglodytes verus ) and sooty mangabeys ( Cercocebus atys atys ). In both species, rather than increasing their own access to preferred partners, bystanders intervened mainly when an alliance between groomers could have a negative impact on them: when the lower-ranking groomer was close to the bystander in rank, when either groomer was an affiliation partner whose services they could lose, or the groomers were not yet strongly affiliated with each other. Thus, bystanders in both species appear to monitor grooming interactions and intervene based on their own dominance rank and social relationships, as well as triadic awareness of the relationship between groomers. While the motivation to intervene did not differ between species, mangabeys appeared to be more constrained by dominance rank than chimpanzees.

This study attempts to assess the impact of corruption on economic growth in the Mediterranean countries, during the period from 1998 to 2007. Econometric analysis using panel regression has been adopted to test this effect. Individual effects models such as random effects model and fixed effects model were applied to the study sample of 160 observations, and to choose the suitable model, we implemented several tests. For our analysis, we used a basic model that includes the dependent variable GDP per capita as a factor of economic growth and the corruption perception index as the independent variable concerned. Then we completed the model with several standardized macroeconomic control variables mentioned above and applied the individual effects models. The outcomes illustrate that corruption has a negative impact on the selected Mediterranean countries&rsquo; economic growth.

Objective: To empirically analyze the link between nonperforming loans and investments along with the role of political governance. The estimation technique used is the fixed effects model including both the country and timMethods: e fixed effects. The dataset consists a panel of 103 countries with annual data over the period from 2000 to 2017. A unique composite political governance index has been prepared combining the six existing governance indicators via Principal Component Analysis (PCA). Findings: It is found that NPL has significant negative impact whereas, governance has significant positive impact on investments as per expectations. However, it is found that the negative impact of NPL on investment gets stronger in presence of good governance. This is a paradoxical result and further attempts has been made to rationalize the outcome. Applications: The study empirically proves the theory of negative impacts of NPL on investment in the economy. Furthermore, the role of political governance has been scrutinized. No prior works have been carried out on this topic. The paradoxical result in this study has opened up new areas for research. An extensive literature review has been provided along with a detailed discussion on the possible measures to tackle with the problems. JEL Classification: C3, E6, G0.

The Impact

Severe economic downturns are typically characterized by a high incidence of job losses. The available evidence suggests that job losers suffer short-run earning losses that persist in the long run, are more likely to remain unemployed, suffer negative health impacts, and experience an increased likelihood of divorce. Job losses have therefore the potential to generate spillover effects for other members of the household, including children. This comes about because most of the negative consequences of job loss have a direct effect on variables that enter both the production function of cognitive achievement and the health production function. Workers who lose their jobs are likely different from those who remain employed in ways that are unobserved to the researcher and that might, in turn, affect child outcomes. Omitted variable bias poses a challenge to obtaining causal estimates of parental job loss. The way the literature has tried to approximate the ideal experiment has mainly depended on whether the child outcome under analysis could be observed both before and after the shock (i.e., both before and after parental job loss), normally relying on job losses coming from plant closures or downsizes and/or individual fixed effects. A survey of the literature shows that father’s job losses seem to have a detrimental impact on outcomes measuring children’s health and school performance. The impact of mother’s job losses on these same outcomes is mixed (including negative, null, and positive impacts). The impact on more long-term outcomes is less clear, with very mixed findings when it comes to the effect of parental job loss on college enrollment, and small impacts on earnings. In many studies, though, average effects mask important differences across subgroups: the negative impact of parental job loss seems to be mostly concentrated on disadvantaged households.
