Media has one of the most important and under-recognized influence on health, development and behavior of children and adolescents. Television is still the most popular form of media among children and adolescents. In the last 50 years, more than a thousand researches have been carried out in the world showing the great impact of television on children and adolescents. Television shapes the attitudes, beliefs and behaviors of children and adolescents and strongly influences their perception of reality. The high impact of television is neither recognized by children nor adults; they estimate that the media affect all others except themselves. Television can positively influence a child?s prosocial behavior and acquisition of certain types of knowledge. However, the positive effects have been much less common and usually obtained at a younger age (3-5 years). Most of the studies provide a persistent and robust findings indicating the correlation between exposure to television and a variety of health problems (such as obesity, low physical activity, elevated cholesterol, diabetes, high blood pressure, etc.) and an increased risk of certain types of behavior (like poor dietary habits, less sleep, smoking, violent behavior, alcoholism, drug addiction, etc.). The research results show that the potentials of television with beneficial effects on children have not been realized; the list of negative effects is much longer and much more diverse; and strategies to reduce the negative effects of television do not apply. The documented findings on the impact of television should elicit serious concern, not just from parents and educators but from many others such as physicians, public health advocates, entertainment industry, politicians, and government.

The cardiac effects of exogenously administered insulin for the treatment of diabetes (DM) have recently attracted much attention. In particular, it has been questioned whether insulin is the appropriate treatment for patients with type 2 diabetes mellitus and heart failure. While several old and some new studies suggested that insulin treatment has beneficial effects on the heart, recent observational studies indicate associations of insulin treatment with an increased risk of developing or worsening of pre-existing heart failure and higher mortality rates. However, there is actually little evidence that the associations of insulin administration with any adverse outcomes are causal. On the other hand, insulin clearly causes weight gain and may also cause serious episodes of hypoglycemia. Moreover, excess of insulin (hyperinsulinemia), as often seen with the use of injected insulin, seems to predispose to inflammation, hypertension, dyslipidemia, atherosclerosis, heart failure, and arrhythmias. Nevertheless, it should be stressed that most of the data concerning the effects of insulin on cardiac function derive from in vitro studies with isolated animal hearts. Therefore, the relevance of the findings of such studies for humans should be considered with caution. In the present review, we summarize the existing data about the potential positive and negative effects of insulin on the heart and attempt to answer the question whether any adverse effects of insulin or the consequences of hyperglycemia are more important and may provide a better explanation of the close association of DM with heart failure.

This systematic review of reviews was conducted to examine housing precarity and homelessness in relation to climate change and weather extremes internationally. In a thematic analysis of 15 reviews (5 systematic and 10 non-systematic), the following themes emerged: risk factors for homelessness/housing precarity, temperature extremes, health concerns, structural factors, natural disasters, and housing. First, an increased risk of homelessness has been found for people who are vulnerably housed and populations in lower socio-economic positions due to energy insecurity and climate change-induced natural hazards. Second, homeless/vulnerably-housed populations are disproportionately exposed to climatic events (temperature extremes and natural disasters). Third, the physical and mental health of homeless/vulnerably-housed populations is projected to be impacted by weather extremes and climate change. Fourth, while green infrastructure may have positive effects for homeless/vulnerably-housed populations, housing remains a major concern in urban environments. Finally, structural changes must be implemented. Recommendations for addressing the impact of climate change on homelessness and housing precarity were generated, including interventions focusing on homelessness/housing precarity and reducing the effects of weather extremes, improved housing and urban planning, and further research on homelessness/housing precarity and climate change. To further enhance the impact of these initiatives, we suggest employing the Human Rights-Based Approach (HRBA).

Abstract The situation of crisis produced by the Coronavirus (COVID-19) pandemic poses major challenges to societies all over the world. While efforts to contain the virus are vital to protect global health, these same efforts are exposing children and adolescents to an increased risk of family violence. Various criminological theories explain the causes of this new danger. The social isolation required by the measures taken in the different countries, the impact on jobs, the economic instability, high levels of tension and fear of the virus, and new forms of relationships have all increased levels of stress in the most vulnerable families and, therefore, the risk of violence. In addition, mandatory lockdowns imposed to curb the spread of the disease have trapped children in their homes, isolating them from the people and the resources that could help them. In general, the restrictive measures imposed in many countries have not been accompanied by an analysis of the access to the resources needed to reduce this risk. It is necessary to take urgent measures to intervene in these high-risk contexts so that children and adolescents can develop and prosper in a society which is likely to undergo profound changes, but in which the defense of their rights and protection must remain a major priority.

Digital transformation provokes a great deal of uncertainty among employees. To gain insights into how employees manage the uncertainty driven by digital transformation and also how leaders can support them, this study has drawn on the theory of communication and uncertainty management (TCUM), which posits that the impact of uncertainty varies by how individuals appraise it and social support enhances positive appraisal. Based on those tenets, the current study advanced the following hypotheses: (a) uncertainty has direct and indirect negative effects on employees’ appraisal of digital transformation, self-efficacy, and job performance; (b) in contrast, direct supervisors’ transformational leadership has direct and indirect positive effects on appraisal, self-efficacy, and job performance; and also (c) transformational leadership moderates the impact of uncertainty. SEM with 4-wave time-separated data ( N = 873 employee-supervisor dyads in Japan) found support for these hypotheses. The obtained findings are discussed with reference to TCUM, transformational leadership, and other relevant literature.

PurposeReligious doctrines generally encourage people to behave ethically. However, in daily life, individuals notice inconsistencies between religious beliefs and behavior, leading them to ask, in the context of commerce, why religious consumers would behave unethically. The purpose of this study was to investigate the impact of consumers' intrinsic and extrinsic religiosity on their ethical behavior. Specifically, the moderating effect of ethical ideology on the relationship between Indonesian consumers' religiosity and their ethics was examined by means of a survey.Design/methodology/approachThe data derived from the questionnaire were complemented by convenience samples of Indonesians living in Daerah Istimewa Yogyakarta (DIY) in central Java. The researchers distributed 600 questionnaires in two major shopping malls and several housing areas in the region, of which 467 were completed and returned, for an overall response rate of 77.8%.FindingsThe results indicated that the participants' intrinsic religiosity negatively impacted their ethical beliefs and was mediated by their idealistic ethical ideology. The present study also found that idealism had negative effects on three of the four dimensions of the consumer ethics scale (CES) (actively benefiting, passively benefiting and questionable behavior), while relativism had positive effects on two of the dimensions (passively benefiting and questionable behavior.Research limitations/implicationsOne limitation of the present study was that the analysis did not distinguish among the religions practiced by the respondents to the questionnaire.Originality/valueThis is one of the first few studies investigating the mediating role of ethical ideology in a religious society. This study contributes to the literature on these issues in theoretical and managerial terms by extending the Hunt-Vitell theory (1986) to the context of consumer ethics.

This paper provides the first estimates of the net impact of CETA participation on the components of CETA participants' post-program earnings. Employing a sample of 1975 CETA enrollees and comparison groups drawn from the March 1978 CPS using a nearest-neighbor matching technique, the authors estimate statistically significant negative effects on men's earnings and statistically significant positive effects on women's earnings. These results stem partly from the impact of CETA participation on the likelihood of being employed after leaving the program (negative for men, positive for women), but also from a negative impact on hours worked during the year and hourly wage rate for men and a large positive impact on hours worked per week and weeks worked per year for women.

Abstract This paper explores the international transmission of U.S. tax shocks. Using structural vector autoregressions, we study the impact on the German economy and on German tax legislation. Our results suggest that, after a U.S. tax cut, German GDP increases only moderately. Positive effects via the income channel outweigh negative effects stemming from price developments. Significant changes in the transmission channels arise by distinguishing between the types of the U.S. tax shock. German tax policy either reacts with diametric measures, or remains passive when considering the whole sample period. For a sample starting in 1980, we find that, in particular, after U.S. corporate income tax cuts, tax reductions are also implemented in Germany.

Purpose The purpose of this paper is to review several influential empirical studies that examine the performance of state-owned enterprises (SOEs). The paper undertakes a citation analysis of journals, authors and titles in the area of privatization and firm performance in general, and assesses the impact of privatization on the performance of SOEs in particular. Design/methodology/approach The methodology is based on a systematic and structured review of over 100 papers published in economics, public management, business strategy and related social sciences. The systematic review is based on citation analysis of journals, authors and titles. The journal and author citation counts were tabulated by leveraging the databases of SCImago Journal Rankings and Google Scholar and filtered it to find out the most highly cited journals and authors. The structured review is based on the framing opinion with respect to major findings, variables selected, measurement techniques and statistical tools applied by different researchers. The impact is measured through coding a value “P” in case of positive effects, “N” in case of negative effects and “NT” in case the study found both positive and negative effects. Findings The citation analysis reveals that American Economic Review, Journal of Financial Economics, Review of Financial Studies and Journal of Finance as the top-cited journals, and Megginson and Netter (3,468), Megginson et al. (1,737), Djankov and Murrell (1,356), Boardman and Vining (1,320), Balsam et al. (1,094) and DeWenter and Malatesta (1,018) as the top-cited authors in this particular research field. While majority research studies have revealed a significant improvement in the performance of SOEs in the post-privatization period, few studies have reserved their impact as neutral or even negative in some respects. Originality/value Given that economic transitions, corporate governance, and performance of SOEs have attracted a great attention from public management and business strategy scholars in recent years, this paper aims to summarize a large number of empirical studies that examine the performance of SOEs. The paper would be useful to future researchers especially the beginners and early career researchers in terms of its current trends, selection of variables, measurement techniques and statistical tools applied.
