The purpose of this paper is to assess the reliability of questionnaires as a method of quantifying household food waste (FW), thus providing context regarding the validity of existing Italian estimates.

A total of 30 households were involved in a diary study that was conducted for one week. The participating households were first asked about their FW quantities in a questionnaire. Half of the households who filled their diaries properly were then audited through waste sorting analysis performed on their garbage. Non-parametric tests were used to test for differences in FW estimates between audited and non-audited households, as well as differences among estimates obtained through different quantification methodologies.

Edible FW was estimated to be 489 grams per week based on questionnaires, and 1,035 grams per week based on diaries. In the audited sub-sample of households, FW estimates were 334 grams per week based on questionnaires, 818 grams per week based on diaries and 1,058 grams per week based on waste sorting analysis.

Given the small sample size in the present study, future studies can utilize larger samples to assess whether the differences identified in estimates can be replicated. Future studies can also inquire into the behavioral biases that led consumers to underestimate their FW.

Results of the present study point against the use of questionnaires to quantify household FW, hence raising some doubt on the reliability of existent Italian estimates. Where waste sorting is unfeasible, the use of adjustment methods or diaries is suggested to better inform policies.

This study is one of the first on FW quantification that tests three different methodologies on the same sample, and is the first to do so in Italy, where estimates are still very poor.

Depression is a common and serious medical illness, considered as a public health issue because it interferes with the interpersonal, social and professional functioning of the individual, and its frequency is constantly increasing. According to a recent review, approximately 34 per cent of nursing students had experienced depression worldwide. The university period may represent a moment in which the mental well-being of students is subjected to stress with a relative predisposition to the development of diseases related to mood disorders. The purpose of this study is to estimate the prevalence and examine the socio-demographic correlates of depressive symptomatology.

In April 2019, a questionnaire was administered to all the nursing students of University of Palermo of the three years of course, accompanied by informed consent. Multivariable logistic regression was performed. The statistical significance level chosen for all analyses was 0.05. The results were analyzed using the STATA statistical software version 14. Results are expressed as adjusted odds ratio (aOR) with 95 per cent confidence intervals.

The sample consists of 493 students who completed the questionnaire, and the average age of the sample participants is 21.88 years. The multivariable logistic regression model shows that the risk to have depressive symptomatology is significantly associated with the following independent variables: female gender (aOR 1.91), being single (aOR 1.87), second year of study (aOR 1.94), third year of study (aOR 1.92), not performing regular physical activity (aOR 1.78) and perceived low health status (aOR 3.08).

This study shows that belonging to the female gender, being further along in the years of study, having a chronic illness and perceiving a low state of health are all factors that can increase the risk of developing the symptoms of depression; rather, regular physical activity, friendship and romantic relationships can be considered factors protecting them from the risk of falling into depression that can undermine both the study and work performance. Certainly, it is important to analyze all the involved variables to improve the global health not only of the nursing students but of all the students.

Few studies have analysed how to actively manage strategic networks (SNs) to achieve individual and collective goals and create value. This paper aims to examine the influence of network management on the value created by SNs and the mediation role of resources and relationship quality.

The authors distributed a survey to 126 companies linked to SNs in the Brazilian information and communication technology sector. This study tested the hypothesized relationships using partial least squares structural equation modelling.

This study found that network management directly influences value creation. Furthermore, the exchange and combination of resources mediate the relationship between the two constructs. Surprisingly, the quality of the relationships does not mediate the relationship between management and the value created. However, it positively impacts the exchange and combination of complementary resources.

This study provides a new interpretation of the determinants of value creation in SNs. The results contribute to the theory by demonstrating that the relationship between network management and value creation is strengthened when the exchange and combination of resources between network participants occur. In turn, these are positively influenced by the quality of relationships established in the network, thus providing a new interpretation of the determinants of value creation in SNs.

Motivated by legitimacy theory, this paper aims to examine comprehensively corporate social responsibility (CSR) disclosure in Southeast Asian (Association of Southeast Asian Nations [ASEAN]) countries with the aim of disentangling whether such disclosures are the result of a proactive stance or a reaction to regulations.

After a content analysis of CSR stand-alone reports that relies on the Global Reporting Initiative as the basis for comparison, a multivariate analysis is carried out while controlling for firm-specific incentives and industry, country and year fixed effects.

The paper finds that CSR disclosure increased across the entire ASEAN. Although this increase cannot be directly ascribed to the introduction of regulations in Indonesia and Malaysia, the latter may have impacted choices of disclosure media. In countries where reporting requirements have become mandated, mandatory reporters show low levels, and voluntary reporters high levels, of CSR disclosure. The paper also finds that the attainment of CSR awards is related to disclosure. Additional analyses reveal a substitution effect between voluntary and mandatory incentives in countries with high levels of law enforcement.

The evidence suggests that the introduction of regulations can be effective in improving the level and breadth of CSR reporting only in the presence of institutions that ensure the enforcement of the disclosure regulations.

The evidence suggests that organizations are reluctant to report on issues such as child labor, human rights and corruption. Organizations opportunistically employ related disclosure strategies that deviate from the underlying CSR performance.

The paper analyzes not only the level and breadth of CSR disclosure but also the motivation for its use across the still under-investigated ASEAN area, thus allowing an examination of the influence of institutional incentives above and beyond the firm-specific factors that drive CSR activities.
