Inequality is an essential factor for the alleviation of poverty. In Cameroon, most of the households derive their livelihoods from non-wage income and a better understanding of how different variables affect income inequality is a way to reduce those inequalities and improve social welfare. Studies carried out so far barely make out the determinants among non-wage earners. This study sets out to identify these determinants, using the regression-based decomposition technique and data obtained from the 2005 Employment and Informal Sector Survey (EISS) undertaken by the National Statistic Institute (INS) in Cameroon. Results show that the total inequality of an hourly active income ensues from the ratio of age/experience and unobserved individual heterogeneity among non-wage earners.

This paper devises a new method for using the information contained in income-generating equations to “account for” or “decompose” the level of income inequality in a country and its change over time. In the levels decomposition, the shares attributed to each explanatory factor are independent of the particular inequality measure used. In the change decomposition, methods are presented to break down the contribution of each explanatory factor into a coefficients effect, a correlation effect, and a standard deviation effect. In an application to rising earnings inequality in the United States, it is found that schooling is the single most explanatory variable, only one other variable (occupation) has any appreciable role to play, and all of schooling’s effect was a coefficients effect.

Given the rapid growth of the Chinese cruise market, several Chinese cities are attempting to become a hub for cruise ships. The aim of this study is to evaluate the competitiveness of those cities with regard to hosting cruises. It employs a cloud model that transforms the qualitative description of competitive indicators into quantitative measurement and assesses the competitive advantage and specialization of the top homeports in China. Questionnaires are delivered to experts from eight cruise ports in China and the cloud model based on 14 evaluation factors is used to analyze the competitiveness of the ports under investigation. The result shows that the city’s scale, population, and development have been the main factors for assessing the competitiveness of port cities. The research provides insight about the Chinese cruise port cities’ competitiveness, which is particularly useful for future development decision and marketing strategies of ports and prospective destinations.

The gender gap in the employment in industries differs based on the industries. Even if construction industry (CI) is a labor-intensive industry, women employment rate is significantly low in the CI. CI is one of the significant labor-intensive industries having environmental footprint. As reduction in its environmental footprint can contribute to environmental sustainability, investments in CI and in reduction in its environmental footprint can have multiplier effect on the countries’ development as well as on the sustainable development (SD). Increase in the women employment in the CI can support achievement of sustainable development goals as it can support reduction in the gender gap in this industry. Furthermore, it can support sustainability performance of the CI as women have potential to prioritize sustainability criterion in their decision-making processes. Especially, women at the top management levels can foster their companies’ sustainability performance. Based on an in-depth literature review, this chapter investigates roles of empowerment of women and increasing women employment in supporting environmental sustainability and SD. This chapter identifies causes of the low employment rate of women in the CI. Furthermore, this chapter examines ways for empowering women and increasing their employment rate in the CI to support environmental sustainability and SD. Additionally, recommendations on future policies and strategies at the CI level to support reduction in the gender gap to enhance CI’s role in the environmental sustainability are provided. This chapter can be useful to policy-makers, researchers and professionals.

Instrumental approaches to norms treat their enforcement as problematic and suggest that self-interested actors are unlikely to sanction. We suggest an alternative conceptualization of the norm enforcement problem. Research shows that social rewards can offset sanctioning costs, thereby encouraging enforcement. The issue then becomes how individuals determine what to sanction. We suggest that the typicality of behavior may provide a clue. We identify conditions under which atypical behavior may be punished. Consistent with existing instrumental approaches, we find that atypical behavior is sanctioned if it detracts from group welfare. We also find evidence pointing to the importance of a non-instrumental factor – perceptions of a behavior's social desirability.

Despite efforts to reduce environmental pollution and wasteful fossil fuel use, electric vehicles (EVs) are still rare on the road. Why is it so challenging to get widespread EV adoption? One significant factor on which it heavily depends is one's awareness and understanding of EVs. However, due to an absolute lack of knowledge on the part of the populace, this factor becomes a huge impediment to the uptake of EVs. A systematic review of the electronic database Scopus for the years 2003–2022 was carried out on ‘EV awareness and adoption of EV’ while considering the ‘Preferred Reporting Items for Systematic Reviews and Meta-analysis’ (PRISMA) standards. A three-step identification process resulted in the ultimate detection of 41 papers, which were then thoroughly examined. A conceptual framework that encompasses the three key awareness aspects that influence EV adoption is developed. To encourage greater uniformity among EV researchers, this study's conclusions serve as a foundation for operationalising upcoming research efforts within a predetermined framework. The authors must therefore be optimistic that lingering technological, legislative, cultural, behavioural and business-model barriers may be overcome over time through widespread dissemination of knowledge and awareness related to EVs, making it possible for everyone to switch to greener, more economical and more efficient transportation solutions.

Advances in Group Processes publishes theoretical analyses, reviews, and theory-based empirical chapters on group phenomena. The series adopts a broad conception of “group processes.” This includes work on groups ranging from the very small to the very large, and on classic and contemporary topics such as status, power, exchange, justice, influence, decision-making, intergroup relations, and social networks. Previous contributors have included scholars from diverse fields including sociology, psychology, political science, philosophy, computer science, mathematics, and organizational behavior.
