The widespread introduction of genetically modified (GM) crops may change the effect of agriculture on the environment. The magnitude and direction of expected effects are still being hotly debated, and the interests served in this discussion arena are often far from those of science and social welfare maximization. This chapter proposes that GM crops have net positive environmental effects, while regulatory responses focus mainly on environmental concerns, giving an unbalanced picture of the regulatory context. This unbalance supports the hypothesis that environmental concerns about GM crops have been politically instrumentalized and that more attention should be paid to regulatory responses considering the environmental benefits of this technology. It is also argued that a number of environmental effects have not yet been quantified and more research is needed in this direction.

Heritability studies attempt to estimate the contribution of genes (vs. environments) to variation in phenotypes (or outcomes of interest) in a given population at a given time. This chapter scrutinizes heritability studies of adverse health phenotypes, emphasizing flaws that have become more glaring in light of recent advances in the life sciences and manifest most visibly in epigenetics.

Drawing on a diverse body of research and critical scholarship, this chapter examines the veracity of methodological and conceptual assumptions of heritability studies.

The chapter argues that heritability studies are futile for two reasons: (1) heritability studies suffer from serious methodological flaws with the overall effect of making estimates inaccurate and likely biased toward inflated heritability, and, more importantly (2) the conceptual (biological) model on which heritability studies depend – that of identifiably separate effects of genes versus the environment on phenotype variance – is unsound. As discussed, contemporary bioscientific work indicates that genes and environments are enmeshed in a complex (bidirectional, interactional), dynamic relationship that defies any attempt to demarcate separate contributions to phenotype variance. Thus, heritability studies attempt the biologically impossible. The emerging research on the importance of microbiota is also discussed, including how the commensal relationship between microbial and human cells further stymies heritability studies.

Understandably, few sociologists have the time or interest to be informed about the methodological and theoretical underpinnings of heritability studies or to keep pace with the incredible advances in genetics and epigenetics over the last several years. The present chapter aims to provide interested scholars with information about heritability and heritability estimates of adverse health outcomes in light of recent advances in the biosciences.

While environmental sustainability may have been intensified by different occurrences such as global warming, increased carbon emission, loss of biodiversity and natural resource depletion, there are concerns that rising population combined with the quality of institutions have serious implications on the attainment of environmental sustainability. While this may seem factual, tackling environmental problems by adopting population reduction policies might not necessarily guarantee a sustainable environment without addressing the quality of institutions. This chapter examines the effect of population growth on environmental sustainability as well as the interactive effect of population growth and institutional quality on environmental sustainability in West Africa region, using data from 2006 to 2019. Adopting the System Generalized Method of Moment method, findings indicate that population growth has a positive but insignificant effect on environmental sustainability. Population growth when interacted with institutional quality had negative and significant effect on environmental sustainability. The result demonstrates that environmental problems cannot be effectively addressed through population policy alone, hence the additional need for strong and institutional quality to ensure environmental sustainability in the region.

This study draws on the natural resource-based view to analyze the effects of technologies, managerial commitment, and firm strategy on sustainability performance, in terms of both environmental and social profits. It also examines how the effect of green technologies on sustainability performance can be triggered by a managerial commitment to sustainability issues, and by the adoption of a prospector strategy. Multiple linear regression was used to test research hypotheses on a sample of 426 Spanish tourism firms. The results provide important insights into the importance of the adoption of explorer strategies fostering the strategic exploitation of green technologies to obtain new efficient processes, organizational procedures, and products. This research also shows the contingent moderating effect that managerial commitment exerts on the strategic implementation of green technologies for sustainability performance.

This chapter analyzes the indirect effects of environmental management system (EMS) implementation and its certification and relates these to international governance in the context of new public environmental management. Building on a comprehensive quantitative dataset, it assesses the effects of ISO 14001 and EMAS (Eco-Management and Auditing Scheme) certification as well as temporal experience with EMS implementation on organizational activities outside the scope of EMS, while taking into account embeddedness and interaction effects. The analysis reveals heterogeneous effects, with limited evidence of embeddedness and interaction effects. As well, no influences of national business systems can be identified. Implications for the role of national governments in implementing sustainability strategies, even beyond environmental management, and aspects of standard flexibility in the process of governing firms to implementing such strategies in an international context are discussed.
