Abstract

In this chapter, we review empirical research evidence on the relationship between stressors and catecholamines (i.e., adrenaline and noradrenaline) and cortisol. With respect to acute stressors, both laboratory and field research have shown that the exposure to stressors leads to an increase in catecholamine and cortisol levels. With respect to more chronic stressors, research evidence is less consistent. Chronic mental workload was found to be related to elevated adrenaline levels. With respect to cortisol responses the interaction between workload and other variables seems to play a role. Empirical studies suggest that chronic stressors affect the responsivity to acute stressors. Research showed that after the exposure to stressors catecholamine and cortisol recovery is delayed.

Abstract

In recent decades, oxytocin (OT) has been extensively studied across disciplines. Yet, the role of OT has been discussed little in the context of politics. This chapter proposes that studying the role of this hormone can enrich and advance the study of politics. The chapter reviews the previous findings on OT categorized into two sections: one that focuses on the biological mechanisms and therapeutic potentials and another that focuses on the effects on social behaviors. This review is not exhaustive but is intended to bring political scientists up to date with the progress in OT studies. Next, this chapter highlights that studying the role of OT in political context will benefit both the OT and political science literature, since there is currently a great interest in the context-dependent nature of OT. I highlight several research questions that can be answered at this intersection. Rather than waiting for other disciplines to complete unfolding the precise role of OT, students of biopolitics can make important contributions. Political science can further understand the biological underpinnings of concern for others and partisan behaviors, while OT applied to real-world settings would demonstrate how different contexts shape its effects.

Abstract

Human performance, particularly that of the warfighter, has been the subject of a large amount of research during the past few decades. For example, in the Medline database of medical and psychological research, 1,061 papers had been published on the topic of “military performance” as of October 2003. Because warfighters are often pushed to physiological and mental extremes, a study of their performance provides a unique glimpse of the interplay of a wide variety of intrinsic and extrinsic factors on the functioning of the human brain and body. Unfortunately, it has proven very difficult to build performance models that can adequately incorporate the myriad of physiological, medical, social, and cognitive factors that influence behavior in extreme conditions. The chief purpose of this chapter is to provide a neurobiological (neurochemical) framework for building and integrating warfighter performance models in the physiological, medical, social, and cognitive areas. This framework should be relevant to all other professionals who routinely operate in extreme environments. The secondary purpose of this chapter is to recommend various performance metrics that can be linked to specific neurochemical states and can accordingly strengthen and extend the scope of the neurochemical model.

Abstract

This chapter reviews the underlying technologies of cryptoassets, including fundamental cryptographic primitives used in distributed ledger technologies and permissionless blockchain technologies and their consensus protocols such as proof-of-work and proof-of-stake. It discusses the pros and cons of existing approaches to improve blockchain scalability and considers the requirements for security and decentralization. The chapter also examines the following techniques: layer 1 tuning, layer 1 sharding, and layer 2 solutions. It concludes with an overview of technologies to swap cryptoassets off-chain, technical requirements for cross-chain transactions, and reviews cross-chain atomic swap implementation using hashed time lock contracts.

Abstract

The importance of anabolism and regeneration is related to lack or loss of control. This chapter discusses the psychophysiological basis for such relationships. In the threat of lost control, energy mobilisation is activated and regeneration is inhibited – since regeneration (repairing) has low priority in emergency situations. This pattern can be traced on several psychophysiological levels, from the brain to most of the cells in the body. Such a mechanism explains why the body becomes vulnerable and increasingly sensitive to load when threat of lost control is excessive and long lasting. In several empirical examples, various indicators of anabolism and regeneration have paralleled improvement versus deterioration in psychosocial conditions, in particular lack or loss of control. In these studies, indicators of anabolism and regeneration (such as concentration of sex hormones with anabolic and regenerative functions in blood and saliva) have been followed in subjects going through deteriorating versus improving life conditions. The demand-support model is used as a theoretical basis for the discussion.

Abstract

Purpose – This chapter addresses the transformation of patient into consumer, focusing on the specific population of human egg recipients. This work also analyzes medicine, and reproductive medicine and egg donation specifically, as marketplaces, particularly as they function in the Internet environment.

Methodology – This chapter utilizes a content analysis of egg donation related websites using both inductive and deductive coding schemes.

Findings – Egg donation related websites and their practices do indeed fit the model of a reproductive medicine marketplace, particularly those practices related to marketing strategies and cost.

Originality/value – This work focuses on the Internet as a primary location for a reproductive medicine marketplace, and develops a new understanding of the ways in which consumers are transformed by and operate in this market. It also demonstrates the emerging need for policy to govern this marketplace.

Abstract

This longitudinal study reports on the development of an integrative curriculum for Medical English courses, which arose as a need on March 11, 2020, when the World Health Organization (WHO) made the assessment that COVID-19 was characterized as a pandemic and its effects became apparent on nursing students in the Department of Nursing at a State University in Turkey. The curriculum was designed using content and language-integrated learning (CLIL) by the ESP practitioner after observing the nursing students’ unexpected reactions to the onset of COVID-19 because of the unfiltered information about COVID-19, as Chiolero (2020) concisely described, “unprecedented in human history” (p. 1). Curriculum development included four stages in this study: preparation, curriculum design, implementation and evaluation. Data were collected using observation of the nursing students and self-reflective reports through triangulation of time and methods and analyzed using thematic analysis. The salient themes in the data analysis included increased awareness, increased confidence, contribution to professional development, the positive effect on mood and feelings, critical thinking, note-taking (because of new scientific information and new term), and ESP practitioner’s positive effects on students (n = 59).
