A systematic review of country-specific drivers and barriers to household food waste reduction and prevention.

Food waste is a global challenge that threatens the sustainable development of human societies. Although food waste is produced in all stages of the food supply chain, household food waste is the biggest contributor to the food waste fraction. In this research, we systematically reviewed 54 empirical studies to explore drivers and barriers to household food waste reduction and prevention. Key aspects, such as comprehension and perception of food waste issues, practices and lifestyles, were examined. Our findings suggest that a great understanding of the impact of one's food waste on health, environment and economy directly promotes food waste management. Additionally, the food waste issue is not attributed to a single factor, it may differ varies across countries. The majority of the reviewed literature on household food waste comes from European countries, where similar geographical, economic and cultural characteristics may lead to comparable drivers and barriers. This could be the reason for showing optimistic experience to the respective food waste management interventions. However, the applicability of these findings and interventions to regions beyond Europe are uncertain. Future studies should also be expanded to include regions such as Asia, North America, Africa, Oceania, Latin America and the Caribbean. To support the sustainable management of household food waste, mapping country-specific food waste determinants is crucial in developing easy-to-implement food waste interventions that can specifically address the food waste issue in each country.

A bibliometric analysis of emerging adulthood in the context of higher education institutions: A psychological perspectives.

In recent years, there has been a rise in studies aimed at better understanding the needs and traits of emerging adults and the role that higher education institutions play in their development and success. Despite the relevance of higher education institutions to the emerging adulthood development, there has been scant work done to synthesise the literature on this topic. A bibliometric method was utilised to retrieve 2484 journal articles from Web of Science (WoS). Utilizing co-citation analysis and co-word analysis, we determined the most influential publications, mapped the knowledge structure, and predicted future trends. The results of the co-citation analysis indicate five clusters, while the co-word analysis indicates four. The results could be used as a roadmap for the future of research on emerging adults by a variety of interested parties, including policymakers, university administrators, funders, and academics.

Parenting Practices and Adolescents' Mental Health: The Mediating Role of Perceived Maternal and Paternal Acceptance-Rejection and Adolescents' Self-Efficacy.

Parenting practices are essential in promoting children's mental health, especially in effective and ineffective parenting. The use of ineffective parenting practices is no longer encouraged in the west; however, it remains a common practice among Asian households. Ineffective parenting consists of inconsistent discipline, corporal punishment, and poor monitoring which may result in mental health consequences. Thus, this study assessed the mediating effects of adolescents' self-efficacy and parental acceptance-rejection on the relationship between ineffective parenting practices and adolescents' mental health. The current study involved a total of 761 school-going Malaysian adolescents aged 13-18 (38.5% males; Mage = 15.65; SDage = 1.43). This study utilized a cross-sectional design where it measured adolescents' mental health, ineffective parenting practices, parental acceptance-rejection, and adolescents' self-efficacy. Both paternal and maternal parenting practices and acceptance-rejection were measured independently. Adolescents' self-efficacy and perceived paternal and maternal acceptance-rejection were found to be significant mediators for ineffective parenting practices and adolescents' mental health. Our findings suggest that ineffective parenting practices will result in perceived parental rejection and lower self-efficacy which in turn resulted in poorer mental health among adolescents. It means parents should be mindful of their parenting approaches as they have a direct and indirect impact on the mental health of their offspring.

The pornography use and its addiction among emerging adults in Malaysia: Perceived realism as a mediator.

Past studies have demonstrated a link between pornography use and addiction to pornography, the underlying mechanism of the association is still unclear. This study intended to examine the mediating role of perceived realism of pornography in the association between pornography use and addiction among emerging adults in Malaysia. This study recruited 222 self-identified pornography users (M age = 21.05; SD Age = 1.68; 75.1% male respondents) via the purposive sampling method. The correlation results indicated positive associations among pornography use, addiction to pornography, and perceived realism of pornography. Further, the perceived realism of pornography significantly mediated the association between pornography use and addiction to pornography after controlling for gender. Thus, this study has provided a fundamental understanding on the perceived realism role of pornography in explaining the association between its use and addiction. Although it is unlikely to stop illegal pornography use, the results pointed out a need to guide emerging adults in pornography use via media literacy programmes.

Cybervictimization and Depression among Adolescents: Coping Strategies as Mediators.

Studies have shown the relationships among cybervictimization, coping strategies, and depression, but no study has examined the mechanism that links the three variables. Accordingly, this study used the transactional model of stress and coping theory as a conceptual framework and proposed that coping strategies are mediators for the effects of cybervictimization on depression. A total of 387 adolescents were recruited by using the purposive sampling method. The results showed that cybervictimization is not directly associated with depression. All the coping strategies are found to be associated with cybervictimization, but only the avoidant coping strategy is the statistical mediator for the effects of cybervictimization on depression. This study's findings suggest that the transactional model of stress and coping theory may provide a framework in the area of cyberbullying and recommend more actions to be taken in order to reduce the use of avoidance coping strategies among victims of cyberbullying.

Problematic Internet Pornography Use and Psychological Distress among Emerging Adults in Malaysia: Gender as a Moderator.

Internet pornography use (IPU) refers to Internet-based sexually explicit materials that are ultimately used to elicit sexual feelings or thoughts. The accessibility of Internet pornography could lead to excessive exposure to pornographic messages, posing a risk to heavy users' psychological health. This paper offers a preliminary understanding of the relationship between Internet pornography use and psychological distress among emerging adults and the moderating role of gender in the association. This cross-sectional study has taken a purposive sampling approach to recruit 144 emerging adult pornography users via the online survey method. The results indicated that males reported having more problematic Internet pornography use, and there were no gender differences in psychological distress. Meanwhile, gender is a significant moderator between Internet pornography use and psychological distress. The females were found to be more psychologically affected by their problematic Internet pornography use than the males. Overall, this study has provided a novel finding of the moderating role of gender in problematic Internet pornography use and psychological distress in the Malaysian context. This study also calls for a gender-focused sexual health programme for Malaysian emerging adults. Furthermore, the scores of problematic IPU in this study raise a concern over the effectiveness of current sex education in Malaysia. The scores may highlight the need to provide education targeting Internet pornography use.

Association Between Self-Esteem and Happiness Among Adolescents in Malaysia: The Mediating Role of Motivation.

Adolescence is the developmental process of becoming an adult. This journey of physical and psychological maturation is filled with challenges and hormonal chaos, and teenagers experience unhappiness at times. From a psychological perspective, this study aimed to examine the association between motivation, self-esteem and happiness; and to explore the mediating role of motivation in the association between self-esteem and happiness among adolescents in Malaysia. 480 secondary school students were recruited using a multistage cluster sampling method and answered the Malay versions of the Subjective Happiness, Brief Motivation and Rosenberg Self-esteem scales. Both self-esteem and motivation were found positively correlated to happiness. The hypothetical mediating role of motivation on the association between self-esteem and happiness was also supported, indicating that individuals with higher self-esteem have higher motivation which may result in greater happiness. Since the direct association between self-esteem and happiness remained significant, a partial mediation of adolescents' motivation between self-esteem and happiness is indicated. The results showed that perceived self-esteem plays a role in predicting happiness and the presence of motivation enhances happiness, providing an insight to nurture happier adolescents for parents and educators in Malaysia.
