Abstract
Classical definitions of motivation typically involve two main components: direction and activation. Motivated behavior is directed toward or away from particular stimuli (i.e., appetitive and aversive motivation). Furthermore, activational aspects of motivation refer to the observation that motivated behavior is characterized by substantial activity, vigor, persistence, and exertion of effort in both the initiation and maintenance of behavior. Although separate neural systems direct organisms toward distinct motivational stimuli (e.g., food, water, sex), there appears to be a common circuitry regulating behavioral activation and the exertion of effort. Mesolimbic dopamine is one of the brain systems mediating activational aspects of motivation and exertion of effort. This system integrates aspects of motivation and motor control functions involved in the instigation of action. Research on the neurobiology of effort has contributed to our understanding of the pathophysiology of neurological and psychiatric disorders that are characterized by motivational dysfunction.

Abstract
In this chapter, the author examines the way in which the purchase and delivery infrastructure of darknet cryptomarkets shapes the experience of opiate drug use and dependence. It uses the concept of social time and posits that the illicit drug distribution system reshapes two temporal dimensions shaping the experience of drug users. There is the experience of time located in the pharmacology of the drug and in the body of the drug user, which evokes experiences of withdrawal and dependence. Then there is the socio-technical embedding of the delivery system and governance structures which support or impinge on the autonomy of the user. This ‘drug time’ is both a benefit and a cost of engaging in cryptomarket use. The market infrastructure can give users the opportunities to more carefully manage their drug time, while also creating new risks of non-delivery that can sharpen experiences of dope sickness. The author concludes that the growing professionalisation, digitisation, and commercialisation of the drug market increasingly embed drug time in material infrastructures mediated through technical systems.

Abstract
Purpose – The objective of this research is to know the correlation of stress level with the degree of depression in the elderly at a nursing home in Lhokseumawe in the year 2017.
Design/Methodology/Approach – This research is analytic using a cross-sectional approach with a total sampling method. The total number of samples was 55 respondents.
Findings – The results showed that the elderly in a Lhokseumawe nursing home at average are at mild stress level to medium degree of depression. Pearson correlation test results show that there is a correlation between stress level and degree of depression in elderly in the Lhokseumawe nursing home in 2017 with medium strong relationship (r = 0.406; p = 0.002).
Research Limitations/Implications – We expect that the elderly living in the orphanage avoid negative thinking about themselves and the future, eliminating feelings of guilt or regret about past mistakes, taking adequate rest and maintaining a diet to avoid stress so as to prevent the onset of depression.
Originality/Value – In addition the study increases the theoretical understanding of the correlation between stress level and degree of depression in elderly at nursing home.

This study contributes to the understanding of the health effects of pesticides exposure and of how pesticides have been and should be regulated.
Abstract
Purpose
This study contributes to the understanding of the health effects of pesticides exposure and of how pesticides have been and should be regulated.
Design/methodology/approach
This study presents literature reviews for the period 2000–2013 on (i) the health effects of pesticides and on (ii) preference valuation of health risks related to pesticides, as well as a discussion of the role of benefit-cost analysis applied to pesticide regulatory measures.
Findings
This study indicates that the health literature has focused on individuals with direct exposure to pesticides, i.e. farmers, while the literature on preference valuation has focused on those with indirect exposure, i.e. consumers. The discussion highlights the need to clarify the rationale for regulating pesticides, the role of risk perceptions in benefit-cost analysis, and the importance of inter-disciplinary research in this area.
Originality/value
This study relates findings of different disciplines (health, economics, public policy) regarding pesticides, and identifies gaps for future research.

Abstract
A pandemic causes abrupt and unanticipated disruptions in many facets of society. A lot of authorities have quickly turned to online teaching methods. The best methods for online teaching have become a hot topic of discussion due to this urgent fast transmission. It was difficult to teach physiology to medical and paramedical students online because of concerns about how to give the students an effective interactive online teaching practice and how to guarantee successful outcomes. Therefore, three approaches have been individually applied to medical and nursing students for the first time in the physiology department of the Faculty of Medicine in Rabigh, King Abdulaziz University. Through online lectures and assignments, the strategies attempted to capture the students’ interest and interaction. The second-year nursing students were given a mind map project to complete after the lecture. The third-year medical students used a crossword puzzle game to test the students’ understanding. The third-year medical students were presented with short stories to better comprehend the physiological processes covered in the lectures. Overall, the three instructional strategies received positive feedback from the students. Incorporating such cutting-edge and imaginative educational approaches, in conclusion, could significantly aid in managing the pressures that arise during pandemics.

Abstract
Global leadership is a vibrant and still emerging field of study. As scholarship grows in this area, the boundaries of the field become more defined. This has a direct impact on curriculum selection for courses and degree programs focused on global leadership. This article begins by exploring how emerging areas of study become recognized as disciplines and applies this knowledge to the global leadership discipline. We also look at doctoral-level degree programs in global leadership, comparing, and contrasting their offerings and approaches, and reflecting on global leadership doctoral education’s role in the ultimate crafting of the discipline. Finally, the curriculum strategies within the doctoral program in global leadership at Indiana Tech are discussed to illustrate the complex and multidisciplinary approach required to prepare global leadership scholars-practitioners.
