Understanding the economic and environmental benefits of nature, in particular trees and forests, can lead to better vegetation management and designs to optimize environmental quality and human health for current and future generations. Computer models have been developed to assess forest composition and its associated effects on environmental quality and human health. While research is still needed regarding many of the environmental services that trees and other ecosystem elements provide, resource managers can utilize existing models to better understand the role of vegetation in improving human health and environmental quality, lower costs of maintenance, and increase resource stewardship as an effective means to provide economic savings to society.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Payment for Environmental Services (PES) are market-based policy instruments. Which compensate private resource managers financially for the environmental services their forests provide. As forest PES policies are increasingly implemented; further research is needed to quantify their environmental benefits and to strategize their improved efficiency. This dissertation evaluates PES policy outcomes from a quantitative analysis within the specific case study of Ecuador's Socio Bosque Program (Span.: Programa Socio Bosque-PSB). The PSB is a national forest PES program instituted in 2008. The dissertation aims to bridge the gap in knowledge regarding the role of PES policies in preventing deforestation and forest degradation. It approaches this aim by presenting methods which integrate and analyze data in a way which progresses the science of conservation policy evaluation. Ultimately, the insights provided advance the science of conservation policy thereby preventing the needless degradation and loss of forest ecosystems. The specific objectives of the overall dissertation are to: (1) better understand the relationship between variations in the structure PES contracts and forest owner enrollment, and (2) go beyond measuring the effect of conservation payments in preventing deforestation to estimate their effect in preventing forest degradation.

Across five samples (i.e., apartment, car, garment, bike and food sharing), this paper shows that there are several reasons why customers want to maintain a relationship with a sharing service provider. Our paper contributes to research on the sharing economy and loyalty research by showing the diverse effects of economic, social and environmental benefits on customer loyalty. In contrast to the sharing industry’s communication to “serve a better world”, community or environmental motives do not generally drive consumers’ intentions to use a sharing provider again. Economic reasons dominate in all five sharing sectors. Thus, the economic perspective on the sharing economy trumps the motive of “doing good for others”. In the case of all five samples, it is self-centered benefits that drive customers to remain loyal. In consequence, sharing providers that would focus primarily on the social and environmental reasons of their customers would implement less effective means. Thus, their customers might be less loyal. One reason for the lower impact of social and environment benefits might be due to the industry itself. Consumers might for example lack comprehensive and reliable information about the environmental effects of sharing services. Thus, evaluating and communicating potential effects for the environment might help to increase consumers’ loyalty in the future. Furthermore, it is in the field of mobility services where all three benefits increase customer loyalty. Whereas carsharing consumers are mostly motivated by economic benefits, bike sharing consumers mostly maintain their relationship because of their desire to belong to a group. These different findings illustrate that specific transport services are used because of the different motives of consumers. The economic benefits of carsharing stem very probably from the high(er) costs of car purchases and their maintenance costs. Buying a bike requires less effort and, thus, economic reasons are less relevant. The importance of social benefits for bike sharing might result from several bike sharing firms investing vast sums of money in recent years and, thus, the visibility of the bikes in public. Moreover, on social media, these firms particularly emphasize the use of bikes in touristy and big cities, thus signaling belonging to a group of mindful and knowledgeable citizens. In consequence, consumers might feel that they are part of a voguish group as it was shown that trend affinity increase repurchase intentions for Airbnb accommodation. The findings also show that loyalty towards providers of apartment sharing is mostly driven by economic benefits. This can be explained by two reasons. First, the apartment sharers mainly advertise that people can save money. Second, consumers of apartment sharing might prefer apartment sharing because they travel more frequently than others. Thus, they need to focus on reasonable prices to continue to travel frequently. The benefit of belonging also increases loyalty, but to a lesser extent. Thus, pursuing the idea of belonging to a group of similar-minded people increases customer loyalty. However, we explain the rather small effect on loyalty with the lack of intense contact with the apartment provider and/or neighbors of the apartment or house. It appears that apartment users seem to cognitively prefer the idea of being a part of a group but not necessarily engage with others in the tourist spot. Furthermore, there is no proven effect of environmental motives on the loyalty of apartment sharers. This can be explained with either the lack of knowledge about the environmental effect, or the knowledge that apartment sharing might be less beneficial to the environment than communicated. To conclude, our paper provides not only detailed findings about five industries of the sharing economy but also delineates management implications for each single sector. In summary, we suggest that sharing providers should not transfer marketing means from other sharing sectors without reflecting upon this beforehand. The drivers of consumers’ loyalty are diverse and marketing means in one industry will be less effective in another.

Research on social and environmental accounting (SEA) has mainly concentrated on disclosure of SEA by corporate bodies, where investigations on ones attitude towards SEA are rarely discussed. SEA is a medium that develops relationships between business and society, community and nature. In addition, SEA involves a concept of sustain ability; where natural resources need to be sustained for the needs of future generations (Alhabshi et al., 2003). SEA also tries to recognise the role of accounting in sustainable development and the use of environmental resources. There are arguments that the young generations today are not fully aware of preserving these natural resources as well as handling social and environmental issues wisely. This perhaps link closely to their belief and cultural background. Hence, this paper examines the influence of gender and belief factors on the undergraduate students’ attitude towards SEA. Four dimensions of belief (fixed ability, quick learning, simple knowledge and certain knowledge) proposed by Schommer (2005) were adapted to analyse how belief factors have influence on their attitude towards SEA. An independent sample t-test was used to examine the relationship between gender and students’ attitude towards SEA. Spearmen’s correlation was employed to show the relationship between belief and attitude towards SEA. The results revealed that gender differences did not show influences on their attitude towards SEA. It was found that there is a significant relationship between belief and students’ attitude towards SEA. Students who believe on the importance of SEA tend to report positive attitude towards SEA. Perhaps findings of this study may provide some information on the SEA education and further be incorporated in the syllabus.

Nutraceuticals have been around for quite some time. As the nomenclature suggests, they are placed somewhere between food (nutra-) and medicine (-ceuticals) in terms of their impact on human health. Researches have focused on the impact of various types of nutraceuticals on health, their efficacy in health promotion and disease prevention, and often on suitable uses of certain categories of nutraceuticals for specific health issues. However, we are still far from utilizing the immense potential of nutraceuticals for benefiting human health in a substantial manner. We review the available scholarly literature regarding the role of nutraceuticals in health promotion, their efficacy in disease prevention and the perception of nutraceuticals' health benefits by consumers. Thereafter we analyze the need for regulation of nutraceuticals and various provisions regarding the same.

This book provides the first detailed account of the role of revolutionary justice in the early Soviet state. Law has often been dismissed by historians as either unimportant after the October Revolution amid the violence and chaos of civil war or even, in the absence of written codes and independent judges, little more than another means of violence. This is particularly true of the most revolutionary aspect of the new justice system, revolutionary tribunals—courts inspired by the French Revolution and established to target counter-revolutionary enemies. This book paints a more complex picture. The Bolsheviks invested a great deal of effort and scarce resources into building an extensive system of tribunals that spread across the country, including into the military and the transport network. At their peak, hundreds of tribunals heard hundreds of thousands of cases every year. Not all ended in harsh sentences: some were dismissed through lack of evidence; others given a wide range of sentences; others still suspended sentences; and instances of early release and amnesty were common. This book, therefore, argues that law played a distinct and multifaceted role for the Bolsheviks. Tribunals stood at the intersection between law and violence, offering various advantages to the Bolsheviks, not least strengthening state control, providing a more effective means of educating the population on counter-revolution, and enabling a more flexible approach to the state’s enemies. All of this adds to our understanding of the early Soviet state and, ultimately, of how the Bolsheviks held on to power.

The first purpose of this chapter is to highlight the impact of the food system on environmental and human health. The delivery of secure affordable food is a political imperative. Unfortunately, the food system that delivers it is environmentally blind. Food prices do not effectively reflect the value of food and often seriously mislead on the costs and impacts of food production. For example, actual food production takes place in a failed market—the value of environmental services such as water and the supporting ecosystems are not taken into account. The second purpose is to summarize and expose the political economy of the different ‘market’ modes of the food system. It is shown that there are weak players such as underrewarded and undervalued farmers who support society by producing food and stewarding our unvalued environment. The inadequacies of accounting systems are also critiqued.

Background: Vaccinating dogs against rabies is an effective means of reducing human rabies. Methods: We analyzed 1,327 clinically diagnosed human rabies deaths and mass dog vaccination (MDV) data during 2006–2018 to quantify the impacts of MDV on human rabies incidence in Bangladesh and a subset of rabies death data (n = 422) for clinico-epidemiological analysis. Results: We found a positive and increasing trend of dog population vaccination (P = .01 and τ = 0.71) and a negative and declining trend (P < .001 and τ = −0.88) of human rabies cases (correlation coefficient, −0.82). Among 422 human rabies death cases, most victims (78%) sought treatment from traditional healers, and 12% received postexposure prophylaxis (PEP). The mean incubation period of rabies cases with exposure sites on the head and neck (35 days) was shorter than the upper limb (mean, 64 days; P = .02) and lower limb (mean, 89 days; P < .01). MDV is effective for reducing human rabies cases in Bangladesh. Conclusions: Creating awareness among the animal bite victims to stop relying on traditional healers rather seeking PEP, addressing the role of traditional healers through an awareness education program in respect to the treatment of dog bites, ensuring availability of PEP, and continuing to scale up MDV can help prevent human rabies deaths.Funding: NoneDisclosures: None

AbstractTo demonstrate the causative role of gut microbiome in human health and diseases, we first need to identify, via next-generation sequencing, potentially important functional members associated with specific health outcomes and disease phenotypes. However, due to the strain-level genetic complexity of the gut microbiota, microbiome datasets are highly dimensional and highly sparse in nature, making it challenging to identify putative causative agents of a particular disease phenotype. Members of an ecosystem seldomly live independently from each other. Instead, they develop local interactions and form inter-member organizations to influence the ecosystem’s higher-level patterns and functions. In the ecological study of macro-organisms, members are defined as belonging to the same “guild” if they exploit the same class of resources in a similar way or work together as a coherent functional group. Translating the concept of “guild” to the study of gut microbiota, we redefine guild as a group of bacteria that show consistent co-abundant behavior and likely to work together to contribute to the same ecological function. In this opinion article, we discuss how to use guilds as the aggregation unit to reduce dimensionality and sparsity in microbiome-wide association studies for identifying candidate gut bacteria that may causatively contribute to human health and diseases.

The role of women in economic development and the global environment is vital for progressing them towards the United Nations sustainable development goal (SDG-5) that emphasized the need to empower women in every walk of life. The study examines women’s autonomy in the sustainable development agenda under China’s open innovation system from 1975 to 2019. The study employed an autoregressive distributed lag (ARDL) model, vector autoregressive (VAR) Granger causality, and innovation accounting matrix to estimate parameters. The existing data are summarized and collated in the context of China to explain as a correlational study. The results show that women’s autonomy moderated with technology spills over to decrease greenhouse gas (GHG) emissions and substantiate the hump-shaped relationship between them. The increased spending on research and development (R&D) activities, patent publications, and renewable energy consumption empowers women to be equipped with the latest sustainable technologies to improve environmental quality. The pollution haven hypothesis verifies a given country, where trade liberalization policies tend to increase polluting industries to set up their plants that engaged in dirty production that exacerbate GHG emissions. The causality estimates confirmed that technological innovations and renewable energy consumption leads to women’s autonomy. In contrast, females’ share in the labor force participation rate leads to an increase in renewable energy consumption. Thus, it is evident that there is a positive role of women in the country’s sustainable development.

AbstractEmerging evidence suggests that liquid–liquid phase separation (LLPS) represents a vital and ubiquitous phenomenon underlying the formation of membraneless organelles in eukaryotic cells (also known as biomolecular condensates or droplets). Recent studies have revealed evidences that indicate that LLPS plays a vital role in human health and diseases. In this review, we describe our current understanding of LLPS and summarize its physiological functions. We further describe the role of LLPS in the development of human diseases. Additionally, we review the recently developed methods for studying LLPS. Although LLPS research is in its infancy—but is fast-growing—it is clear that LLPS plays an essential role in the development of pathophysiological conditions. This highlights the need for an overview of the recent advances in the field to translate our current knowledge regarding LLPS into therapeutic discoveries.
