Abstract:
The purpose of this chapter is to overview the sport mood model and mood research conducted in disability sport. Researchers in disability sport have examined mood in a limited fashion, with an overreliance on the Profile of Mood States (POMS) scale, which measures vigor, confusion, depressed mood, anger, fatigue, and tension. A clear limitation of the POMS scale is the underrepresentation of positive mood states that athletes experience. Many of the researchers in disability sport have asked modest questions, such as do athletes with acquired versus congenital disabilities have more positive mood states? Other researchers have used the positive and negative affective schedule and have been able to offer a more well-rounded commentary on various positive and negative affective states and how they are related to other cognitions and sport performance. The chapter concludes with the recommendation that researchers use models of emotion and mood such as the 12-point affect circumplex (12-PAC) model and address how core affect can be assessed to reflect mood or emotion.

Abstract:
This book focuses on organizations that function across dissimilar nations and cultures. These organizations are everywhere, regulating economic rhythms of nations and people on a worldwide scale and at an unprecedented rate. Naturally, scholars and practitioners interested in the study of organizations in dissimilar national contexts need to know more about these social systems, how they evolve, what forces affect them positively, and what affects them negatively. This chapter focuses on the issue of developing effective global organizations. Several guidelines are presented with special emphasis on those that deal with converting a global presence into a major competitive advantage on a sustained scale. The notion that globalization in the 21st century is largely a complex phenomenon characterized by high levels of ambiguities and volatility is emphasized. The strategies that global organizations can adopt in this environment are presented.

Full text
Abstract:
Because pain is in part an affective experience, investigators over the past several decades have sought to elaborate the nature of pain-affect connections. Our evolving understanding of the intersection of pain and affect is especially relevant to intervention efforts designed to enhance the quality of life and functional health of individuals managing chronic pain. This chapter describes how pain influences arousal of the vigilance/defensive and appetitive/approach motivational systems and thus the affective health of chronic pain patients. The focus then moves to the dynamic relations between changes in pain and other stressors and changes in positive and negative affect as observed in daily life and laboratory-based experiments. A consensus emerges that sustaining positive affect during pain and stress flares may limit their detrimental effects and promote better functional health. The authors consider the implications of increased understanding of the dynamic interplay between pain and affective experience for enhancing existing interventions.

Abstract:
This chapter discusses the relationship between affect and eating behavior from two points of view—how affect shapes eating behavior and how eating behavior generates affect—arguing that appreciating how affect influences eating behavior depends on understanding in what way eating generates affect. It first discusses biological and social-cultural perspectives on the pleasure of eating and posits that the inherently rewarding experience of eating is compromised by concerns about the health consequences of eating too much or by eating the wrong foods. The second part of this chapter explains in what way both negative and positive affect influences consumption and highlights the contrast between theoretical notions on the phenomenon of emotional eating and empirical findings. It elaborates on new avenues for investigating the association between affect and eating, including the role of positive emotions, emotions as justifications for overeating, and eating as a coping strategy for dealing with negative emotions.

Full text
Abstract:
In depolarization to effect neuronal activations,, electrical charges are delivered to the neuron to affect the electrical potential across the neuronal membrane to subsequently affect voltage-gated ionic conductance channels. The orientation of the field of electrical charges to the neuronal membrane is critical. Electrical charges flow from the negative contact to the positive contact. The negative electrostatic charge “pushes” negative charges onto the outer surface of the neuron, which results in depolarization of the neuronal membrane. Neurons near the positive contact will not have negative electrical charges deposited on the outer surface, will not be depolarized, and thus, are not activated. Likewise, neurons whose membranes are oriented parallel to the lines of electrical forces that move electrical charges will not receive the electrical charges and, consequently, will not be activated. The electronics of the DBS systems are designed to control the electrostatic forces so as to control the activations of the nervous system to generate benefit and avoid adverse effects.

Abstract:
In this chapter, we first review the existing literature on cross-cultural studies on compassion. While cultural similarities exist, we demonstrate cultural differences in the conception, experience, and expression of compassion. Then we present our own work on the cultural shaping of compassion by introducing Affect Valuation Theory (e.g., Tsai, Knutson, & Fung, 2006), our theoretical framework. We show how the desire to avoid feeling negative partly explains cultural differences in conceptualizations and expressions of compassion. Specifically, the more people want to avoid feeling negative, the more they focus on the positive (e.g., comforting memories) than the negative (e.g., the pain of someone’s death) when responding to others’ suffering, and the more they regard responses as helpful that focus on the positive (vs. negative). Finally, we discuss implications of our work for counseling, health care, and public service settings, as well as for interventions that aim to promote compassion.

Abstract:
Within psychology, subjective well-being refers to a person’s overall evaluation of the quality of life from his or her own perspective. Traditionally, psychologists have focused on three specific components of subjective well-being: life satisfaction, positive affect, and negative affect, though disagreements exist about precisely how these components should be best measured. Psychological research shows that intuitively appealing predictors of SWB, such as income and health, are typically only weakly correlated with SWB, whereas personality predictors tend to be stronger. This chapter reviews basic psychological research on SWB, addresses questions about the conceptualization and measurement of the construct, and discusses recent attempts to clarify the associations among the various components that are typically studied.

Full text
Abstract:
This chapter brings together the strands of theory and research discussed previously to introduce our theory on inequality and morality. The general argument is that in societies with greater economic inequality, the negative sanctioning-based moral emotions of anger, contempt, disgust, shame, and the like will be more frequent and severe. Societies with lower levels of inequality will conversely normalize and exhibit the more positive moral emotions of self-transcendence (compassion, praise, and empathy). Inequality thus begets negative moral emotions. These various emotional reactions to moral events not only affect everyday interaction, but also overlap with criminal justice systems’ reactions to those who offend societies’ moral codes. The more negative the moral reaction in a society, the more likely events are to prompt feelings associated with condemning others, the more the criminal justice system will be similarly focused on sanctioning as opposed to rehabilitation.

Abstract:
This chapter provides a review of the nascent (but growing) literature on organizational citizenship behavior (OCB) at the within-person level of analysis. We organize our review of the existing literature chronologically, discussing antecedents and consequences of within-person fluctuations in OCB. After providing a narrative review of the literature, we provide a quantitative summary of the literature via meta-analysis, summarizing the within-person relationships between OCB and its most common within-person correlates (i.e., positive affect, negative affect, job satisfaction, stressors, strain, and task performance). Looking to the future of OCB at the within-person level of analysis, we suggest that researchers can contribute to the domain by tailoring the measurement of OCB to the within-person level of analysis, better illuminating the causal direction between OCB and affect, clarifying the relationship between OCB and counterproductive work behavior at the within-person level, expanding the “dark side” of within-person OCB, exploring between-person differences in within-person OCB variability, and incorporating new theories.

Abstract:
The origins of attachment theory and the work of John Bowlby and Mary Ainsworth are described. Four types of child–parent attachment relationships—secure, insecure/anxious, insecure/ambivalent, and insecure/disorganized—are outlined along with the ways each type might manifest itself in the classroom. A longitudinal study, conducted by Alan Sroufe and his colleagues, of the development and effects on learning and interpersonal relationships of different child–parent attachment relationships is described. Teachers too have a history of attachment relationships that can affect how they relate to their students. The chapter describes adult attachment and how one’s attachment history might, positively or negatively, affect one’s ability to build positive, nurturing relationships with students. Specific examples of ways teachers can offset the negative effects of a student’s or their own history of insecure attachment are described.

Martin, Jeffrey J. Athletic Identity. Oxford University Press, 2017. http://dx.doi.org/10.1093/oso/9780190638054.003.0014.

Full text
Abstract:
Some of the first research in disability sport focused on athletic identity using the Athletic Identity Measurement Scale (AIMS). A large body of research has supported a robust finding that athletes with disabilities view themselves as legitimate athletes, whereas they believe that others (e.g., the able-bodied public) do not view them as athletes as strongly. This chapter examines descriptive and correlational research completed with the AIMS. Descriptive work indicates Paralympians relative to recreational athletes have stronger athletic identities. Correlational research indicates that athletes with strong athletic identities are more competitive and confident and have stronger sport intentions. At the same time, athletes with exclusive athletic identities may be at risk for experiencing negative affect when unable to play. Athletes may disinvest in sport and an athletic identity as their skills wane and they anticipate no longer participating in sport. While a disinvestment in athletic identity can be viewed as a self-esteem protective strategy it might also have negative performance ramifications.

Full text
Abstract:
Does wealth accumulation impact subjective well-being? Within a country, household wealth has been shown to improve individual well-being by providing a safety net of protection against negative income shocks, by allowing current and expected consumption flows, and by its potential use as a collateral. At the aggregate level, direct evidence about the relationship between national wealth and happiness is almost non-existent, owing to data limitations and statistical identification problems. However, aggregate wealth impacts well-being indirectly, via positive channels such as institutional quality and improvement in health, life expectancy, and education. Wealth also brings about negative environmental degradations and other damages. The stock of accumulated wealth is also likely to affect happiness indirectly, via its influence on the rate of GDP growth, because both the level of income flows and the rate of income growth have been shown to be factors of higher well-being.

Full text
Abstract:
Self-efficacy theory is one of the most researched topics in sport psychology. This chapter defines self-efficacy and provides an overview of the antecedents and outcomes of strong and weak self-efficacy. An overview of self-efficacy-based research in disability sport is also provided. Correlational work has demonstrated that athletes with strong self-efficacy, relative to athletes with weaker efficacy, have stronger psychological skills, less anxiety, more positive affect, and less negative affect and receive more social support from significant others. Imagery and self-talk are also related to self-efficacy providing theoretical support for these two antecedents. Athletes with strong training self-efficacy also tend to have strong performance self-efficacy. Research examining self-efficacy for pain management and the challenges of training is advocated as well as longitudinal research and intervention work. Similarly, work examining disability and disability sport–specific antecedents and outcomes of efficacy is called for, as is research into coach, team, and referee self-efficacy.

Full text
Abstract:
In addition to theory testing, researchers have also examined if exercise interventions serve to enhance psychological constructs such as self-esteem and behavior such as functional fitness, activities of daily living (ADL), and physical activity. The purpose of this chapter is to review the physical activity (PA) intervention research and offer criticisms and future research directions. Laboratory PA interventions have been effective at increasing physical capacity, muscular strength, walking ability, and reducing body weight, stress, depression, and pain. However, laboratory research has been criticized for lacking ecological validity, thus researchers have also investigated whether lifestyle-type community or field-based interventions are effective. Researchers have shown that increasing social support for PA is effective for adults, and water-based activities help children with cerebral palsy increase their functional fitness. Nontraditional approaches such as yoga, massage, relaxation, and mindfulness training might be considered potential antecedents of reduced negative affect, increased positive affect, and enhanced functional fitness.

Abstract:
The real burden to any sufferer of respiratory disease is shown in the human suffering of the individual. It is increasingly understood that there is a link between the psychological aspects of respiratory disease and morbidity and that patients’ attitudes to illness can affect their ways of coping and, indeed, impact upon their compliance with treatment. Breathlessness is a symptom of many psychological states, both positive and negative; indeed, it is embedded within the English language: ‘It took my breath away! I was breathless with anticipation!’ An understanding of the links between psychological factors and physical symptoms and behaviours is essential to achieve the best possible outcomes for many patients.

This chapter sets out the importance of adolescent mental health—how the first 1,000 weeks of life provide a more robust time frame for health and development—despite being underserved, underresourced, and underdeveloped. Both positive and negative mental health can affect adolescent well-being. There is a growing evidence base on need and emerging interventions that should be incorporated into holistic adolescent services. This chapter provides an overview of pathways of promise, ranging from social protection, individual and group work, parenting and community interventions, and the promise of a pathway in cyberspace. Mental and physical health are intimately intertwined, and no program of provision for adolescents should fail to address mental health and well-being.

Full text
Abstract:
Abstract This book addresses the consequences of legitimacy in global governance, in particular asking: when and how do legitimacy crises affect international organizations (IOs) and their capacity to rule. The book starts with a new conceptualization of legitimacy crisis that looks at public challenges from a variety of actors. Based on this conceptualization, it applies a mixed-methods approach to identify and examine legitimacy crises, starting with a quantitative analysis of mass media data on challenges of a sample of 32 IOs. It shows that some, but not all organizations have experienced legitimacy crises, spread over several decades from 1985 to 2020. Following this, the book presents a qualitative study to further examine legitimacy crises of two selected case studies: the WTO and the UNFCCC. Whereas earlier research assumed that legitimacy crises have negative consequences, the book introduces a theoretical framework that privileges the activation inherent in a legitimacy crisis. It holds that this activation may not only harm an IO, but could also strengthen it, in terms of its material, institutional, and decision-making capacity. The following statistical analysis shows that whether a crisis has predominantly negative or positive effects depends on a variety of factors. These include the specific audience whose challenges define a certain crisis, and several institutional properties of the targeted organization. The ensuing in-depth analysis of the WTO and the UNFCCC further reveals how legitimacy crises and both positive and negative consequences are interlinked, and that effects of crises are sometimes even visible beyond the organizational borders.

Abstract:
Psychosis has probably affected humans since the start of humanity itself, although the construct of schizophrenia is a relatively new phenomenon, dating back to the nineteenth century. Work by Emil Kraepelin and Eugen Bleuler helped consolidate ideas about psychotic disorders, setting the stage for both clinical care and neuroscience research in subsequent centuries. Phenomenologically, psychotic symptoms range from “positive” symptoms (delusions, hallucinations), to “negative” symptoms (avolition, affective blunting), to “disorganization” symptoms (disorganized speech and behavior), which all combine to produce functional deficits. Different psychotic disorders have different combinations of symptoms, which can combine with mood and anxiety symptoms to affect functioning problems in unique ways. These symptoms can be recognized fairly reliably in individuals. Understanding the inner experience of psychosis can help improve patient-centered care.

Abstract:
Course and outcome in schizophrenia and related disorders historically depend on diagnostic conceptualizations, with significant variability even across individuals with the exact same diagnosis. In this chapter, we will review the heterogeneity of course and outcome, providing some context in terms of factors that affect prognosis. Generally speaking, current outcomes are better than previously thought, with three-quarters of individuals having a good prognosis. Although these illnesses cannot be cured, we know that recovery is possible. The best predictors of outcome in schizophrenia are cognitive and negative symptoms (not positive symptoms), along with premorbid functioning, duration of untreated psychosis, and treatment adherence over time. Finally, we will touch on functional outcomes such as risk of violence and suicide, as well as issues around treatment discontinuation.

Abstract:
Advances in technology and an increasingly global marketplace have brought about many positive changes in business, but they have also had some negative effects on workplace relationships. Incrementally and over time, these two drivers of change have significantly reshaped workplace relationships at both the company and employee level. Managers work in this ever-changing context each day, facing the impact of technology and globalization on their emotional lives as well as the ways in which they relate to others in their Credibility Crosses—a concept that is developed in this chapter. Unfortunately, managers often have time only to react to these changes rather than consider how they affect the bigger relationship picture. Consciously understanding the interpersonal impact of technology and globalization provides managers with opportunities to improve workplace relationships.

Abstract:
Social anxiety disorder (SAD) and major depressive disorder (MDD) are prevalent disorders that exhibit a high rate of co-occurrence. Furthermore, these disorders have been shown to be associated with each other, suggesting that the presence of one disorder increases risk for the other disorder. In this chapter, we discuss relevant theories that attempt to explain why SAD and MDD are related. We propose that the available evidence provides support for conceptualizing the comorbidity of SAD and MDD as resulting from a shared underlying vulnerability. There is evidence that this underlying vulnerability is genetic in nature and related to trait-like constructs such as positive and negative affect. We also discuss the possibility that the underlying vulnerability may confer tendencies toward certain patterns of thinking. Finally, we discuss theories that propose additional causal pathways between the disorders such as direct pathways from one disorder to the other. We advocate for a psychoevolutionary conceptualization that links the findings on the underlying cognitions to the shared relation of lower positive affect and the findings on peer victimization. We suggest that, in addition to a shared underlying vulnerability, the symptoms of social anxiety and depression may function as a part of a behavior trap in which attempts to cope with perceived social exclusion lead to even higher levels of social anxiety and depression. Finally, we make recommendations for the best methods for assessing SAD and MDD as well as suggestions for treating individuals with both disorders.

Abstract:
Competition is a normal part of working life. It is expected of both women and men as they enter the workforce, and as they ascend the corporate ladder. Interestingly, women are often vilified for engaging in competition, particularly with members of their own sex. The focus of this essay is intrasexual competition among women in the workplace. It provides a description of workplace competition and its positive and negative consequences for workers and organizations, followed by similarities and differences in women’s and men’s competitive experiences and styles. The ways zero-sum contexts such as tokenism affect social identity and give rise to the intrasexual prejudice and discrimination—most notably, the queen bee—are discussed. The essay ends with a discussion based on the authors’ experimental evidence of intragroup favoritism among women, and a growing body of work underscoring the importance of not expecting women to be allies without accompanying organizational change.

Abstract:
This chapter explores the extent to which political settlements interacting with the rents space affect the nature of the deals space and consequently help explain economic growth in Ghana. The discussions are centred around four break points and therefore five growth episodes for Ghana: pre-1966, 1966–74, 1974–83, 1983–2001, and 2001–14. First, there are signs that the post-2001 period has been more ordered and open than the first twenty-five years after independence. Second, the political settlement has also changed somewhat over the years, from a dominant to a more competitive type. However, it is argued that political patronage remains rife. Third, the chapter finds that the interplay of political settlements and rent space has been important in shaping the nature of the deals space in Ghana. Finally, it highlights two types of positive and negative feedback loop relating to these variables over the years.

Chapter 3 outlines the key questions of the book and the methodology that the book uses to deal with these questions. The questions are as follows: 1. To what extent are functional differentiation and religion compatible? 2. How does vertical differentiation affect the religious landscape? 3. Does the increasing diversity of the religious have a positive or a negative effect on the vitality of religious communities, organizations and markets? Is there a connection here at all? Can we understand the effects of religious pluralization as the relativization of religious claims to validity? Or does the competition between different religious and ideological providers trigger particular efforts to preserve and expand customer bases? In its methodology, the book relies on special case studies and comparative analyses; it integrates studies from the social sciences and history; it uses statistics and representative survey data; and it includes archival research.

Abstract:
Much of the literature has examined how dialectical thinking influences the self, emotions, and well-being. How does dialectical thinking affect valenced evaluations of objects outside of the self? This chapter argues that naive dialecticism shapes the internal consistency, cross-situational consistency, and temporal stability of attitudes and related constructs. It begins with a discussion of how dialecticism leads to greater attitudinal ambivalence or “both-valenced” (positive/negative) evaluations of a wide variety of phenomena. It then examines how dialecticism can explain the cultural variation in ingroup favoring versus ingroup derogating tendencies. The difference between cognitive versus affective components and implicit versus explicit levels emerge as important distinctions in elucidating cultural variation in group-based attitudes. The chapter continues with a discussion of how dialecticism can account for cultural differences in cognitive dissonance, intergroup attitudes and relations, and attitude flexibility and change, and topics for future research are proposed.

Abstract:
Disability status continues to have a significant negative impact on employment outcomes, even in countries with nondiscrimination policies, and outcomes differ by gender and age. These subpar outcomes can be linked to both environmental and psychological factors. The design of jobs and workplaces often limits the ability of workers with disabilities to contribute to their fullest capacity, while stigmatization reduces employer willingness to hire workers with disabilities and make reasonable accommodations to allow them to perform effectively. Exclusion and stigmatization create barriers to the development of a positive self-identity as a person with a disability. Considerably more research is needed to understand how the actions of organizations, leaders, and teams affect the employment outcomes of workers with disabilities and how impacts differ by gender and age. But based upon extant knowledge, there are many actions employers can take to improve outcomes for this group of workers.

Abstract:
This chapter argues that an understanding of social identity processes is critical to understand when and how stigma affects health. This chapter presents a social identity analysis of the relationship between stigma and health and starts from the premise that it is particularly difficult for individuals who belong to stigmatized groups to derive a positive identity from their social group memberships. However, when individuals turn to the stigmatized group, identify with it, and draw social support from others within it, their health will be buffered against some of the negative consequences of discrimination because group memberships—and the social identities that are derived from them—act as psychological resources. Perceptions of the broader sociostructural context that affect appraisals of discrimination and coping with stigma play an important role in determining whether the curing properties of group memberships are unlocked, turning the curse of belonging to a stigmatized group into a cure.

Abstract:
Although palliative and hospice care services are increasingly available, many adults and children still die without this kind of support or receive it only in the last few days of life, as many patients, family members, and clinicians equate the initiation of these services with loss of hope. This chapter presents a model of how hopeful patterns of thinking and a balance of positive and negative affect may facilitate a regoaling process in which individuals transition from cure-seeking goals to other personally meaningful goals that are attainable at the end of life or while living with a serious chronic illness. Understanding different forms of hopeful thinking, goals, and self-concepts among dying patients and their families can help clinicians provide support through this difficult experience and achieve better quality of life and symptom management for patients and better quality of life and long-term adjustment for family members.

Abstract:
This article focuses on methodology in the literature on human resources (HR) management and performance. Whenever a theoretical model of HR and performance is tested and estimated using empirical data, a binary decision regarding whether the model is supported (yes or no) is typically made. If support is found, it is either because the model is correct or the method is wrong (i.e. a false positive, or Type I, error of inference). If support is not found, it is either because the model is wrong or the method is wrong (i.e. a false negative, or Type II, error of inference). The article hopes to help readers to better evaluate the contribution of published research on HR and performance. Second, it hopes to help authors in preparing their work for publication and avoid problems that may otherwise lengthen the review process or adversely affect the publication decision.

Abstract:
Abstract The book studies how U.S. military deployments abroad serve as a tool of public diplomacy that can both support and undermine the international liberal order established by the United States. It develops and systematically tests a theory of public opinion toward the United States, its people, and its global non-invasion military deployments. Positive interactions with servicemembers, including routine daily interactions and the economic flows from a deployment, serve as a form of public diplomacy, improving perceptions of military deployments and the United States as a whole. However, negative events and experiences stemming from deployments, like crime, pollution, and controversial mission types can produce negative reactions among local populations. The book explores these subjects, including chapters devoted to understanding how different forms of contact, reported experiences with crimes involving US service members, and belonging to minority communities, all affect views of the US military presence in a state. We The book also looks at how these factors shape reported involvement in protests against the US, and broader trends in anti-US protest events around the world. The book argues that curtailing servicemember engagement in the community is a policy that can backfire on the US military's long-term objectives, as removing day-to-day positive social interactions with US personnel diminishes one of the main sources of goodwill toward US deployments. It proposes that US policy should focus not on isolating deployed forces from local populations but on regulating interactions in a way that maximizes the potential for beneficial social connections and minimizes harm to host populations.

Abstract:
Positivity Theory suggests that increased exposure to the symbols of judicial authority stimulates positive associations within individuals that help courts build and maintain their legitimacy. Indeed, recent research suggests that exposure to the symbols of judicial authority negates the linkage between decisional disappointment and changes in judgments of institutional legitimacy. However, this research has been conducted on predominantly white samples and fails to account for the possibility that individuals’ group attachments and experiences with legal authorities might affect the extent to which they update their diffuse support for a court in response to a displeasing decision. We therefore examine changes in legitimacy, relying on a nationally-representative survey experiment. The results indicate that respondents are particularly likely to withdraw support from the Court under the condition of seeing the symbols of judicial authority if they have negative personal experiences with the police, and if they are both particularly disappointed in the decision and do not have any strong group attachments.

Abstract:
This chapter examines the relation between personality disorder (PD) and depression, disorders that are commonly comorbid in clinical and community populations. This comorbidity presents both clinical and conceptual challenges. In anticipation of the upcoming introduction of theDiagnostic and Statistical Manual of Mental Disorders(fifth edition;DSM-5), we review research on the associations of depression with both PD and traits in order to help bridge the current and future literatures. Issues distinguishing PD and depression are reviewed, including conceptual concerns, the nature of the associations between depression and PD and traits, and current evidence on associations between depression and PD and chief personality trait dimensions. Data are presented from an ongoing study examining associations between depressive symptoms, maladaptive-range personality, and psychosocial functioning using proposedDSM-5criteria for depression and PD trait domains and facets. Depressive disorders exhibit large associations with negative affect and more moderate links with positive affect and conscientiousness/disinhibition, though there appear to be even more differentiated patterns of associations at the facet level. However, our understanding of the processes responsible for the associations of PD and depression is still limited. Despite this lack of clarity, the links between depression and PD and traits have important clinical implications for assessment and treatment of both disorders. Assessment approaches and challenges are discussed, as well as the implications of co-occurring PD and traits for the treatment of depressive disorders. Finally, future research directions are summarized.

Abstract:
People with disabilities report having a wide range of quality of life. Quality of life is typically determined by life satisfaction, and negative and positive affect. Although people with disabilities face many individual, social, and environmental challenges, they often express a good to excellent quality of life. Having a good quality of life, despite these many challenges, is known as the disability paradox. Similarly, the erroneous assumption by many able-bodied people that individuals with disabilities must have terrible lives is also part of the disability paradox. The purpose of this chapter is to examine research showing how exercise can be an important vehicle to enhance quality of life. An overview of quality of life theories, concepts, measurement, and definitions is presented, followed by a review of the research and the mechanisms behind the association between physical activity and quality of life. For instance, feelings of mastery, increased functional fitness, enhanced social support from group and partner exercise, and biological mechanisms are all plausible mechanisms undergirding the salubrious effects of physical activity.

Abstract:
When it became known in early 2020 that Covid-19 was becoming a global pandemic, it also became clear that governmental responses to the pandemic would have significant effects on democracy and human rights. With two years of data from International IDEA’s Global Monitor of Covid-19’s Impact on Democracy and Human Rights, we can take stock of what has happened and in which areas the events align with or differ from our expectations about how a pandemic might affect these vital areas of public life. This report examines the effects of the pandemic responses in six broad areas: (1) emergency legal responses and civil liberties, (2) freedom of movement, association, and assembly, (3) freedom of expression and media integrity, (4) privacy rights and contact tracing applications, (5) women’s rights and minority rights, and (6) vaccination and fundamental rights. In each of the sections, the report describes the global trends in each of these areas, highlights cases that illustrate both positive and negative examples, and considers what the upcoming challenges will be.

Abstract:
This chapter examines the scaling and diffusion of green entrepreneurship between 1980 and the present. It explores how entrepreneurs and business leaders promoted the idea that business and sustainability were compatible. It then examines the rapid growth of organic foods, natural beauty, ecological architecture, and eco-tourism. Green firms sometimes grew to a large scale, such as the retailer Whole Foods Market in the United States. The chapter explores how greater mainstreaming of these businesses resulted in a new set of challenges arising from scaling. Organic food was now transported across large distances causing a negative impact on carbon emissions. More eco-tourism resulted in more air travel and bigger airports. In other industries scaling had a more positive impact. Towns were major polluters, so more ecological buildings had a positive impact.

Abstract:
Comorbidity between panic disorder and major depression is found in the majority of individuals with panic disorder and a substantial minority of individuals with major depression. Comorbidity between panic disorder and depression is associated with substantially more severe symptoms of each of the disorders, greater persistence of each disorder, more frequent hospitalization and help-seeking behavior, more severe occupational impacts, and a significantly higher rate of suicide attempts. These two disorders share many risk factors, such as neuroticism, exposure to childhood abuse, informational processing biases, and elevated amygdala activation in response to negative facial expressions. Research on the temporal priority of panic disorder and major depression has most frequently found that panic attacks and other symptoms of anxiety predate the onset of the first major depressive episode, but the first depressive episode predates the onset of full panic disorder. Treatment studies indicate that cognitive behavioral therapy (CBT) is the most effective treatment for panic disorder. Other forms of treatment include medication, particularly selective serotonin reuptake inhibitors. Comorbid depression does not appear to affect the outcome of CBT for a principal diagnosis of panic disorder, and CBT for panic disorder has positive, yet limited, effects on symptoms of depression.

Abstract:
This book offers a novel theory and an original use of cross-cultural data to argue that the level of economic inequality in a society is reflected in the emotional experience of its members. People living in societies with greater equality experience more positive, binding emotions on a regular basis, while people living in unequal societies, like the United States, are significantly more likely to regularly experience negative, sanctioning moral emotions. We develop the idea that morality operates at both the societal and individual levels, and develop the thesis that individual moral emotions represent the distal structure of society. We bridge a number of areas in social science, including morality, inequality, social psychology, and the study of emotions. A good deal of work explains how being economically advantaged (or not) contributes to individual tastes, beliefs, values, and choices. Very little work links the extent of the advantages within a society to individual outcomes. We suggest that being advantaged in a relatively equal society leads to different experiences and shared cultures than being advantaged in a highly unequal society. We offer a novel use of established data from a tool drawn from the well-established Affect Control Theory tradition to demonstrate empirical support for our theory. As such, we go beyond previous work by showing data that supports our theory using a method that is designed for cross-cultural comparative research. We aim for this book to stimulate future work via different tools to test our theoretical argument.

Abstract:
Following much other research on musical emotion, this chapter assumes a two-dimensional representation, with one dimension representing valence (positive/negative) and the other representing energy/activity. It is argued that the valence dimension in rock is conveyed primarily by the location of a song’s scale (relative to the tonic) on the “line of fifths”; this captures the well-known major/minor contrast but also allows finer distinctions. The energy dimension is conveyed by a variety of musical parameters including loudness, register, tempo, rhythmic density, and timbral brightness. The chapter also posits a third dimension, complexity, which is taken to be represented experientially by tension; increased tension is caused by unexpected events and by an increase in event density. It has been hypothesized that a moderate level of complexity is optimal for aesthetic enjoyment; this may in part account for the appeal of certain rhythmic patterns, a phenomenon known as “groove.”

Abstract:
RAINBOW: A Child- and Family-Focused Cognitive-Behavioral Treatment for Pediatric Bipolar Disorder is a comprehensive, evidence-based treatment manual designed specifically for children ages 7–13 with bipolar spectrum disorders and their families. Developed by experts in pediatric mood disorders and tested in a randomized clinical trial (RCT), RAINBOW integrates psychoeducation and cognitive-behavioral therapy (CBT) with complementary techniques from mindfulness-based intervention, positive psychology, and interpersonal therapy to address the range of therapeutic needs of families affected by this disorder. Guided by the evidence on the neurobiological and psychosocial difficulties accompanying pediatric bipolar disorder, this treatment targets the child and family across seven core components: Routine, Affect Regulation, I Can Do It, No Negative Thoughts and Live in the Now, Be a Good Friend/Balanced Lifestyle for Parents, Oh How Do We Solve This Problem, and Ways to Get Support. Throughout the treatment, the child and family will learn how to identify mood states and triggers of mood dysregulation, and develop cognitive and behavioral strategies for improving mood stability. Children will build social skills, and caregivers will develop greater balance and self-care in their own lives. The family will learn ways to use routines, problem-solving, and social support to improve overall family functioning. Intended for qualified child-focused mental health professionals, this manual includes the conceptual background of the treatment and user-friendly step-by-step instruction in delivering RAINBOW with families, including handy session outlines and engaging worksheets for the child and caregiver(s).

Smith, Andrew, Guy Osborn, and Bernadette Quinn, eds. Festivals and the City: The Contested Geographies of Urban Events. University of Westminster Press, 2022. http://dx.doi.org/10.16997/book64.

Full text
Abstract:
This book explores how festivals and events affect urban places and public spaces, with a particular focus on their role in fostering inclusion. The ‘festivalisation’ of culture, politics and space in cities is often regarded as problematic, but this book examines the positive and negative ways that festivals affect cities by examining festive spaces as contested spaces. The book focuses on Western European cities, a particularly interesting context given the social and cultural pressures associated with high levels of in-migration and concerns over the commercialisation and privatisation of public spaces. The key themes of this book are the quest for more inclusive urban spaces and the contested geographies of festival spaces and places. Festivals are often used by municipal authorities to break down symbolic barriers that restrict who uses public spaces and what those spaces are used for. However, the rise of commercial festivals and ticketed events means that they are also responsible for imposing physical and financial obstacles that reduce the accessibility of city parks, streets and squares. Alongside addressing the contested effects of urban festivals on the character and inclusivity of public spaces, the book addresses more general themes including the role of festivals in culture-led regeneration. Several chapters analyse festivals and events as economic development tools, and the book also covers contested representations of festival cities and the ways related images and stories are used in place marketing. A range of cases from Western Europe are used to explore these issues, including chapters on some of the world’s most significant and contested festival cities: Venice, Edinburgh, London and Barcelona. The book covers a wide range of festivals, including those dedicated to music and the arts, but also events celebrating particular histories, identities and pastimes. A series of fascinating cases are discussed - from the Venice Biennale and Dublin Festival of History, to Rotterdam’s music festivals and craft beer festivals in Manchester. The diverse and innovative qualities of the book are also evident in the range of urban spaces covered: obvious examples of public spaces – such as parks, streets, squares and piazzas – are addressed, but the book includes chapters on enclosed public spaces (e.g., libraries) and urban blue spaces (waterways) too. This reflects the interpretation of public spaces as socio-material entities: they are produced informally through their use (including for festivals and events), as well as through their formal design and management.

Full text
Abstract:
The primary ANCA-associated vasculitides are granulomatosis with polyangiitis (Wegener's, GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA, Churg-Strauss syndrome, CSS). They predominantly affect small (and medium-sized) vessels and share a variable association with ANCA (anti-neutrophil cytoplasm antibody) directed against neutrophil proteinase 3 (PR3, mainly in GPA) and myeloperoxidase (MPO, mainly in MPA and CSS). Crescentic necrotizing glomerulonephritis and alveolar haemorrhage due to pulmonary capillaritis represent classical (vasculitic) organ manifestations of the ANCA-associated vasculitides (AAV). MPA occurs as a 'pure' small (to medium-size) vessel vasculitis, whereas GPA and CSS are characterized by additional distinct clinical and pathological features. In GPA, granulomatous lesions of the upper and/or lower respiratory tract are a hallmark of the disease. Granulomatous lesions may be large in appearance and occur as space-consuming, infiltrating, and destructive inflammatory masses. GPA is believed to follow a stagewise course with an initial localized form, restricted granulomatous lesions of the upper and/or lower respiratory tract without clinical signs of vasculitis, and a consecutive generalization to systemic vasculitis which may be either non-organ-threatening (early systemic) or organ- and life- threatening (generalized GPA). Rarely, patients arrest in the localized stage and do not progress to systemic disease. In EGPA asthma, hypereosinophilia and eosinophilic organ infiltration (e.g. eosinophilic myocarditis) are typical features of the disease apart from vasculitis. Similarly to GPA, EGPA follows a stagewise course: asthma and eosinophilia may precede full-blown disease for several months or years. Recent cohort studies suggest different phenotypes in EGPA (predominantly vasculitic and MPO-ANCA-positive and predominantly with eosinophilic organ infiltration, usually ANCA-negative). This chapter focuses on the clinical features of the primary AAV and their outcome.

Full text
Abstract:
The atmospheric circulation in the mid-latitudes of both hemispheres is usually dominated by westerly winds and by planetary-scale and shorter-scale synoptic waves, moving mostly from west to east. A remarkable and frequent exception to this “usual” behavior is atmospheric blocking. Blocking occurs when the usual zonal flow is hindered by the establishment of a large-amplitude, quasi-stationary, high-pressure meridional circulation structure which “blocks” the flow of the westerlies and the progression of the atmospheric waves and disturbances embedded in them. Such blocking structures can have lifetimes varying from a few days to several weeks in the most extreme cases. Their presence can strongly affect the weather of large portions of the mid-latitudes, leading to the establishment of anomalous meteorological conditions. These can take the form of strong precipitation episodes or persistent anticyclonic regimes, leading in turn to floods, extreme cold spells, heat waves, or short-lived droughts. Even air quality can be strongly influenced by the establishment of atmospheric blocking, with episodes of high concentrations of low-level ozone in summer and of particulate matter and other air pollutants in winter, particularly in highly populated urban areas.Atmospheric blocking has the tendency to occur more often in winter and in certain longitudinal quadrants, notably the Euro-Atlantic and the Pacific sectors of the Northern Hemisphere. In the Southern Hemisphere, blocking episodes are generally less frequent, and the longitudinal localization is less pronounced than in the Northern Hemisphere.Blocking has aroused the interest of atmospheric scientists since the middle of the last century, with the pioneering observational works of Berggren, Bolin, Rossby, and Rex, and has become the subject of innumerable observational and theoretical studies. The purpose of such studies was originally to find a commonly accepted structural and phenomenological definition of atmospheric blocking. The investigations went on to study blocking climatology in terms of the geographical distribution of its frequency of occurrence and the associated seasonal and inter-annual variability. Well into the second half of the 20th century, a large number of theoretical dynamic works on blocking formation and maintenance started appearing in the literature. Such theoretical studies explored a wide range of possible dynamic mechanisms, including large-amplitude planetary-scale wave dynamics, including Rossby wave breaking, multiple equilibria circulation regimes, large-scale forcing of anticyclones by synoptic-scale eddies, finite-amplitude non-linear instability theory, and influence of sea surface temperature anomalies, to name but a few. However, to date no unique theoretical model of atmospheric blocking has been formulated that can account for all of its observational characteristics.When numerical, global short- and medium-range weather predictions started being produced operationally, and with the establishment, in the late 1970s and early 1980s, of the European Centre for Medium-Range Weather Forecasts, it quickly became of relevance to assess the capability of numerical models to predict blocking with the correct space-time characteristics (e.g., location, time of onset, life span, and decay). Early studies showed that models had difficulties in correctly representing blocking as well as in connection with their large systematic (mean) errors.Despite enormous improvements in the ability of numerical models to represent atmospheric dynamics, blocking remains a challenge for global weather prediction and climate simulation models. Such modeling deficiencies have negative consequences not only for our ability to represent the observed climate but also for the possibility of producing high-quality seasonal-to-decadal predictions. For such predictions, representing the correct space-time statistics of blocking occurrence is, especially for certain geographical areas, extremely important.
