Abstract

Facial expression recognition by human observers is affected by subjective components. Indeed there is no ground truth. We have developed Discrete Choice Models (DCM) to capture the human perception of facial expressions. In a first step, the static case is treated, that is modelling perception of facial images. Image information is extracted using a computer vision tool called Active Appearance Model (AAM). DCMs attributes are based on the Facial Action Coding System (FACS), Expression Descriptive Units (EDUs) and outputs of AAM. Some behavioural data have been collected using an Internet survey, where respondents are asked to label facial images from the Cohn–Kanade database with expressions. Different models were estimated by likelihood maximization using the obtained data. In a second step, the proposed static discrete choice framework is extended to the dynamic case, which considers facial video instead of images. The model theory is described and another Internet survey is currently conducted in order to obtain expressions labels on videos. In this second Internet survey, videos come from the Cohn–Kanade database and the Facial Expressions and Emotions Database (FEED).

Abstract

Purpose

To examine some of the complex relationships that exist between sports work and mental health and illness.

Design/Method/Approach

This chapter draws upon prevalence data, athlete testimonies, and theoretical works to examine: (1) the prevalence of depression and suicide in professional sport and the wider society; (2) athlete experiences of depression and suicidal ideation, particularly among men; and (3) some of the key sociological ideas which might help to explain experiences of mental health and illness in professional sports work.

Findings

Although there are plentiful data on the societal prevalence of depression and suicide, increasing interest in the mental health of professional athletes (and other types of sports workers) has occurred largely in response to individual or clusters of often publicly known, sometimes high profile, cases rather than in response to systematic empirical grounded data. Athlete experiences of mental illness are shown to be related in complex ways to various constraints associated with their public and private lives, to the constraints of their interdependency networks, and to experiences of shame which can have a series of deleterious acute and chronic health costs.

Research Limitations/Implications

Since much of what is currently known about the links between sports work and mental health and illness is derived from largely psychological studies and media-led or autobiographical accounts, more sociological research is needed to better understand the costs of mental health of working in often very public and highly pressurized, medicalized, scientized, and performance-focused performance sport settings.

Abstract

New forms of ‘smart’ mobility have emerged with the advance of information technology. From a public sector perspective, these ambitions have been framed both in terms of innovation and sustainability. The development work of these technologies is in part being subsidised by public actors investing in and funding different types of pilots or experiments in order to ‘test’ these technologies in what is called a real-life environment. This is part of a larger trend of experimental governance in which smart mobility is an important and a possibly growing part. This chapter offers a conceptual analysis of experimental governance by analysing three underlying assumptions in literature and practice (1) the need for extraordinary solutions, (2) the importance of learning by doing and (3) the necessity of collaboration. These three assumptions are analysed in relation to smart mobility experiments in Sweden, and discussed in relation to public values. The concluding discussion elevates a number of normative implications of using experimental governance as a policy instrument for the development of smart mobility.

Abstract

To fulfill their economic and social missions, it is imperative yet challenging for hybrid ventures to demonstrate legitimacy (fitting in) while simultaneously projecting distinctiveness (standing out). One important means for doing so is by adopting and promoting the recent B Corporation certification. Drawing on a comprehensive analysis of the emergence of this certification, we argue that when it comes to promoting their businesses, hybrid ventures should not adopt a one size fits all approach. Rather, their promotion strategies need to be adapted to their specific contexts. We theorize and develop a typology of certification promotion strategies for hybrid ventures based on the relative prevalence of other hybrid ventures in the same regions and industries. We conclude by articulating why the B Corporation movement is a rich and underexplored context for scholarship on hybrid ventures, and highlight several promising future research directions.

Abstract

Cities have long been of interest to international development as well as to criminology. Historically, criminology as a social science emerged as a response to urbanisation and the new opportunities created by cities for criminal activity and victimisation. Thus, Sustainable Development Goal 11 (SDG 11), which ‘aims to make cities and human settlements inclusive, safe, resilient and sustainable’, is ripe for criminological input and analysis. SDG 11 tackles housing and basic services, transport systems, urban planning, cultural and natural heritage, disaster prevention, environmental impact, and safe, inclusive, and accessible green and public spaces. There has been ample criminological research on crime and victimisation in various types of human settlements, on transport systems, on the looting and trafficking of cultural heritage, on crimes associated with natural disasters and on the importance of public leisure areas for crime prevention. Yet many of the above goals, as well as the recommendations emerging from these bodies of research, conflict with each other, and must be problematised in their aim to be inclusive of all. Women and children, the elderly and persons with disabilities are usually the reference groups for inclusion, but globally, there are many other groups, including racial and ethnic minorities, indigenous communities, and LGBTQI individuals that are commonly excluded. The chapter will analyse SDG 11 against the evidence base of urban criminology as well as the challenges for inclusion, given diversity both within-country as well as globally.

Abstract

Stock markets during the day are relatively centralized, while night markets, due to the dominance of electronic trading venues, are fragmented. Though electronic markets at night allow more competition for order flow, they may result in decreased order interaction and decreased transparency. Using transaction data for three exchange traded funds (ETFs), we find that bid–ask spreads are wider at night due to higher order processing costs, market maker rents, and inventory holding costs. Results show that night markets are informationally fragmented and are not able to impound information available in net order flow to the same degree as day markets.

Abstract

This study investigates the impact of socioemotional wealth (SEW) on family firm entrepreneurial orientation (EO) in Saudi Arabia, and the moderating effect of generational involvement on this relationship. Our data set comprises 241 privately, wholly owned family firms. We examine EO as a strategic orientation expressed in terms of both firm behavior and how managers approach risk-taking attitudinally. Our study finds that SEW is positively related to firms’ entrepreneurial behavior, but not managerial attitudes toward risk-taking. However, the positive effects of SEW on firms’ entrepreneurial behavior diminish as the number of generations involved in the family business increases. The broader implications for enabling entrepreneurship within Arab transforming economies adhering to strong cultural tribalistic norms are discussed.

Abstract

The reduction in public services since 2008 has undoubtedly affected some groups, such as disabled people, more than others. Many of these cuts, ostensibly imposed in response to recession, bear similarities to measures previously tried and tested on disabled asylum seekers. I argue that the perception of national crisis was used by government as a smokescreen to expand the population affected by such policies, thereby asserting a predetermined neoliberal agenda of public expenditure cuts.

The inequality of this situation is compounded by the entitlements granted to people deemed exceptionally worthy. The Vulnerable Persons Relocation Scheme for Syrian nationals includes disability among the eligibility criteria, offering considerably greater entitlements than available to asylum seekers. If the response to certain people is markedly different to that offered to others, then negative consequences can be anticipated, as from any other example of inequality. Furthermore, this scheme promotes a significant shift in migrant entitlement. The UK government has no legal obligation towards this group; therefore, those people who are selected are recipients of gifts rather than people claiming their rights. I explore the nature and implications of such differences in entitlement, arguing that inequality in all its manifestations must be challenged to reduce deprivation and to avoid negative consequences for the wider population.
