Crop biodiversity is one of the major inventions of humanity through the process of domestication. It is also an essential resource for crop improvement to adapt agriculture to ever-changing conditions like global climate change and consumer preferences. Domestication and the subsequent evolution under cultivation have profoundly shaped the genetic architecture of this biodiversity. In this review, we highlight recent advances in our understanding of crop biodiversity. Topics include the reduction of genetic diversity during domestication and counteracting factors, a discussion of the relationship between parallel phenotypic and genotypic evolution, the role of plasticity in genotype × environment interactions, and the important role subsistence farmers play in actively maintaining crop biodiversity and in participatory breeding. Linking genotype and phenotype remains the holy grail of crop biodiversity studies.

The Relationship

This paper considers the challenge to global social policy posed by global climate change. It sets side by side global social policies and global climate change policies, and surveys the governance of each. The first part summarises global social policy in recent years, distinguishing (1) the policies and practices pursued in the global arena, and (2) the structures of global governance and the role of significant global actors. The second part repeats this at a greater length for global climate change. The third part then considers the relationship between these two sets of policies/practices and governance structures, in particular the potential conflicts between the pursuit of social justice and environmental sustainability. It identifies two possible responses – compensation and co-benefits – and maps these onto current global actors, before concluding with a radical vision of eco-social policy.

Purpose The purpose of this paper is to investigate whether consumers in pre-owned durable goods markets (such as pre-owned automobiles) purchase products with higher premium/luxury positioning in a vertical line-up compared to consumers in new durable goods markets. The moderating role of brand loyalty on choice is also investigated. Design/methodology/approach The hypotheses are tested using a data set that includes the sales of new and pre-owned vehicles from an independently owned automotive dealer in the Northwestern USA during the first nine months of 2017 (N = 200). An ordered logit regression is used to estimate the relationship between consumers’ purchase of pre-owned vs new vehicles and the premium-level of the model that they choose, while controlling for the vehicle price. Two experimental robustness tests are conducted to provide empirical evidence of the proposed theoretical process. Findings Consumers who purchased pre-owned vehicles chose models with higher premium/luxury positioning compared to consumers who purchased new vehicles, even when controlling for price. This effect was moderated by brand loyalty, such that consumers’ premium-level of purchase was magnified if they previously owned a vehicle of the same brand. The results of an experimental robustness test indicated that consumers’ preference for pre-owned vehicles with higher premium/luxury positioning was because of greater perceptions of the quality along the dimensions of versatility, performance and prestige. Practical implications Sellers of complex durable goods (e.g. automobiles) should consider segmenting their upselling strategies for pre-owned vs new products. They should specifically focus more effort on the upselling of pre-owned durables as buyers appear more likely to pursue premium/luxury alternatives compared to new durables. Further, they should focus upselling efforts for pre-owned durables on brand loyal consumers. Originality/value To the best of the authors’ knowledge, this work is the first to examine consumers’ desire for pre-owned durable goods with premium/luxury positioning in a vertical product line-up. Further, it is also the first to explore the role of brand loyalty in shaping consumer preferences for premium/luxury pre-owned durable goods. As such, it makes an important contribution to an emerging literature exploring the appeal of premium and luxury pre-owned goods. Much work in this area has focused on the motivations that consumers have for buying pre-owned premium and luxury nondurable goods, such as vintage clothing or accessories. By contrast, the present research investigates the appeal of premium/luxury positioning for complex, pre-owned durable goods (vehicles), which are more difficult for consumers to evaluate at the point-of-purchase.

Waste-to-energy (WtE) could prevent the production of up to 50 million tons of CO2 emissions that would otherwise be generated by burning fossil fuels. Yet, support for a large deployment of WtE plants is not universal because there is a widespread concern that energy from waste discourages recycling practices. Moreover, incineration plants generate air pollution and chemical waste residuals and are expensive to build compared to modern landfills that have appropriate procedures for the prevention of leakage of harmful gasses. In the context of the EU, this paper aims to provide a picture of the actual role of WtE as a disposal option for municipal solid waste (MSW), enabling it to be utilized as a source of clean energy, and to address two important aspects of the debate surrounding the use of WtE; namely, (i) the relationship between WtE and recycling, and (ii) the effects of decentralization, waste mobility, and plant ownership. Finally, it reviews the role of the EU as a supranational regulator, which may allow the lower government levels (where consumer preferences are better represented) to take decisions, while taking spillovers into account.

As a result of the increase in global climate change and the development of social networks, the study of ecotourism and the impact of social networks has been getting greater attention. Nonetheless,research examining the impact ofsocial networks on ecotourismhas been limited. This study investigates the relationship between ease of use, perceived usefulness, wordof-mouth (WOM), perceived trust, and tourist attitude towards ecotourism, and examines the moderating role of perceived risk on these relationships in the context of Vietnam. The regression analysis was conducted with data from answers of 231 respondents. The results show that perceived trust has the largest impact on tourist attitude towards ecotourism, which is followed by perceived usefulness. WOM communication has the least impact. The study also highlights the role of perceived risk in moderating the relationship between social networks and tourist attitudes.

In recent years, in line with consumer preferences and due to the effects of global climate change, new trends have emerged in wine fermentation and wine technology. Consumers are looking for wines with less ethanol and fruitier aromas, but also with a good balance in terms of acidity and mouthfeel. Nonconventional yeasts contain a wide range of different genera of non-Saccharomyces. If in the past they were considered spoilage yeasts, now they are used to enhance the aroma profile of wine or to modulate wine composition. Recent publications highlight the role of non-Saccharomyces as selected strains for controlling fermentations mostly in cofermentation with Saccharomyces. In this article, I have reviewed the ability of some bacteria and non-Saccharomyces strains to modulate wine acidity.

Abstract. Background: Lowered eye blink rate may be a clinically useful indicator of acute, imminent, and severe suicide risk. Diminished eye blink rates are often seen among individuals engaged in heightened concentration on a specific task that requires careful planning and attention. Indeed, overcoming one’s biological instinct for survival through suicide necessitates premeditation and concentration; thus, a diminished eye blink rate may signal imminent suicidality. Aims: This article aims to spur research and clinical inquiry into the role of eye blinks as an indicator of acute suicide risk. Method: Literature relevant to the potential connection between eye blink rate and suicidality was reviewed and synthesized. Results: Anecdotal, cognitive, neurological, and conceptual support for the relationship between decreased blink rate and suicide risk is outlined. Conclusion: Given that eye blinks are a highly observable behavior, the potential clinical utility of using eye blink rate as a marker of suicide risk is immense. Research is warranted to explore the association between eye blink rate and acute suicide risk.

The Relationship

Parenting behaviors – specifically behaviors characterized by high control, intrusiveness, rejection, and overprotection – and effortful control have each been implicated in the development of anxiety pathology. However, little research has examined the protective role of effortful control in the relation between parenting and anxiety symptoms, specifically among adults. Thus, we sought to explore the unique and interactive effects of parenting and effortful control on anxiety among adults (N = 162). Results suggest that effortful control uniquely contributes to anxiety symptoms above and beyond that of any parenting behavior. Furthermore, effortful control acted as a moderator of the relationship between parental overprotection and anxiety, such that overprotection is associated with anxiety only in individuals with lower levels of effortful control. Implications for potential prevention and intervention efforts which specifically target effortful control are discussed. These findings underscore the importance of considering individual differences in self-regulatory abilities when examining associations between putative early-life risk factors, such as parenting, and anxiety symptoms.

Abstract. Exposure to traumatic events and the associated risk of developing Posttraumatic stress disorder (PTSD) symptoms is a significant and overlooked concern in the college population. It is important for current research to identify potential protective factors associated with the development and maintenance of PTSD symptoms unique to this population. Emotional intelligence and perceived social support are two identified protective factors that influence the association between exposure to traumatic events and PTSD symptomology. The current study examined the mediating role of social support in the relationship between emotional intelligence and PTSD symptoms. Participants included 443 trauma-exposed university students who completed online questionnaires. The results of this study indicated that social support mediates the relationship between emotional intelligence and reported PTSD symptoms. Thus, emotional intelligence is significantly associated with PTSD symptoms and social support may play an integral role in the relationship between emotional intelligence and PTSD. The current study is the first to investigate the role of social support in the relationship between emotional intelligence and PTSD symptoms. These findings have important treatment and prevention implications with regard to PTSD.

Abstract. This study investigated the mediating role of coping humor in the relationship between emotional intelligence (EI) and job satisfaction. Participants were 398 primary school teachers in China, who completed the Wong Law Emotional Intelligence Scale, Coping Humor Scale, and Overall Job Satisfaction Scale. Results showed that coping humor was a significant mediator between EI and job satisfaction. A further examination revealed, however, that coping humor only mediated two sub-dimensions of EI (use of emotion and regulation of emotion) and job satisfaction. Implications for future research and limitations of the study are discussed.
