A study of consciousness as an ethically significant property and its value and significance in human-animal conflict

In this thesis I argue that current approaches to animal ethics, while valuable for solving cases of indirect conflict between humans and animals, are not equipped to deal with cases where humans and animals are in direct, unavoidable conflict with each other. Those approaches that focus on consciousness as ethically relevant factor however, are superior since they can make distinctions between individuals even with many other factors (level of interest in the conflict, sentience etc.) being equal. I also argue that it is reasonable to attribute consciousness to animals, and that consciousness is ethically relevant and identifiable in the behaviour of animals, even if not directly reportable though language for example. Building on this, I further argue that we can more accurately ascribe consciousness to animals through their intentional behaviour, rather than more traditional indicators such as tool use or language, both to those animals closely related to us and those that are very different to us. This consciousness has ethical relevance, and if we can determine the level of, or type of consciousness that each species in a direct conflict possesses, we can more effectively solve direct, unavoidable conflicts between humans and other animals.Thesis (PhD (Philosophy))--University of Pretoria, 2022.PhilosophyPhD (Philosophy)Unrestricte

A theory of challenge and threat states in athletes: A revised conceptualisation

The Theory of Challenge and Threat States in Athletes (TCTSA) provides a psychophysiological framework for how athletes anticipate motivated performance situations. The purpose of this review is to discuss how research has addressed the 15 predictions made by the TCTSA, to evaluate the mechanisms underpinning the TCTSA in light of the research that has emerged in the last ten years, and to inform a revised TCTSA (TCTSA-R). There was support for many of the 15 predictions in the TCTSA, with two main areas for reflection identified; to understand the physiology of challenge and to re-evaluate the concept of resource appraisals. This re-evaluation informs the TCTSA-R which elucidates the physiological changes, predispositions, and cognitive appraisals that mark challenge and threat states. First, the relative strength of the sympathetic nervous system response is outlined as a determinant of challenge and threat patterns of reactivity and we suggest that oxytocin and neuropeptide Y are also key indicators of an adaptive approach to motivated performance situations and can facilitate a challenge state. Second, although predispositions were acknowledged within the TCTSA, how these may influence challenge and threat states was not specified. In the TCTSA-R it is proposed that one’s propensity to appraise stressors as a challenge that most strongly dictates acute cognitive appraisals. Third, in the TCTSA-R a more parsimonious integration of Lazarusian ideas of cognitive appraisal and challenge and threat is proposed. Given that an athlete can make both challenge and threat primary appraisals and can have both high or low resources compared to perceived demands, a 2x2 bifurcation theory of challenge and threat is proposed. This reflects polychotomy of four parts; high challenge, low challenge, low threat, and high threat. For example, in low threat, an athlete can evince a threat state but still perform well so long as they perceive high resources. Consequently, we propose suggestions for research concerning measurement tools and a reconsideration of resources to include social support. Finally, applied recommendations are made based on adjusting demands and enhancing resources

Editorial: Adaptation to psychological stress in sport

First paragraph: Psychological stress is ubiquitous in sport. Unsurprisingly then, research that examines the antecedents, correlates, consequences, and interventions pertaining to psychological stress in sport is sizable and broad. With this Research Topic we aimed to capture the breadth and depth of work taking place around the theme of adaptation to psychological stress in sport. Pleasingly, 111 authors responded to our call for papers, contributing 25 papers between them. In this Editorial we undertake the difficult task of synthesizing these contributions, and highlight important implications that could influence future research and practice

Mapping palliative care provision in European prisons: an EAPC Task Force Survey

Objectives: Prison populations around the world are ageing and numbers are rising, leading to greater demand for palliative care for prisoners approaching the end of life. This paper reports a survey that was undertaken by the European Association for Palliative Care Task Force on mapping palliative care provision for prisoners in Europe. The Task Force was established to begin to address the gap in research knowledge by exploring prison systems and care provision across different countries. Methods: The survey, developed by the Task Force Steering Committee, consisted of 40 questions in six sections. It was completed through online searches; only data that were publicly available on the internet were included. Numerical data were analysed using descriptive statistics, and thematic comparisons were made of free-text data. Findings: The survey was completed for eight countries: Australia, Belgium, Czech Republic, England and Wales, France, Portugal, Scotland and Slovakia. Three main findings are reported here: healthcare and palliative care provision in prisons, deaths in custody and compassionate release. Despite increasing numbers of older prisoners, relatively few prisons provide inpatient care, and only one country has any prisons that provide dedicated palliative care services. Early release on compassionate grounds is extremely rare in most countries. Conclusion: For the principle of equivalence to be adhered to, facilities for sick and dying prisoners need to be improved, or many more people need to be released on compassionate grounds at the end of life. This mapping study has identified key issues in relation to palliative care in prison and provides the basis for further international research.info:eu-repo/semantics/acceptedVersio

'The show must go on': Event dramaturgy as consolidation of community

Event dramaturgy and cultural performance have not been examined in the literature from a strategic standpoint of fostering the social value of events. Thus, the purpose of this study was to explore the case of the Water Carnival, a celebratory event in a rural community of Southwest Texas, demonstrating the essence of this event as a symbolic social space, wherein event participants instantiate a shared and valued sense of community. A hermeneutical approach was employed, interpreting the event and its symbolisms as a text, combined with findings from ethnographic fieldwork, including participant observation, in-depth interviews and analysis of archival documents. The study examines the ways that dramaturgy in the Water Carnival helps frame the ongoing public discourse for community improvement and enhances social capital. The implications of the study for social leverage of events are discussed. It is suggested that a foundation for strategic social planning is the understanding of events as symbolic social spaces and their embeddedness in community development, which can be accomplished when events are pertinent to public discourse, address community issues, represent an inclusive range of stakeholders, and promote cooperation

The psychology of online activism and social movements:Relations between online and offline collective action

We review online activism and its relations with offline collective action. Social media facilitate online activism, particularly by documenting and collating individual experiences, community building, norm formation, and development of shared realities. In theory, online activism could hinder offline protests, but empirical evidence for slacktivism is mixed. In some contexts, online and offline action could be unrelated because people act differently online versus offline, or because people restrict their actions to one domain. However, most empirical evidence suggests that online and offline activism are positively related and intertwined (no digital dualism), because social media posts can mobilise others for offline protest. Notwithstanding this positive relationship, the internet also enhances the visibility of activism and therefore facilitates repression in repressive contexts

A new pathway for Mannitol metabolism in yeasts suggests a link to the evolution of alcoholic fermentation

No use, distribution or reproduction is permitted which does not comply with these terms.The yeasts belonging to the Wickerhamiella and Starmerella genera (W/S clade) share a distinctive evolutionary history marked by loss and subsequent reinstatement of alcoholic fermentation mediated by horizontal gene transfer events. Species in this clade also share unusual features of metabolism, namely the preference for fructose over glucose as carbon source, a rare trait known as fructophily. Here we show that fructose may be the preferred sugar in W/S-clade species because, unlike glucose, it can be converted directly to mannitol in a reaction with impact on redox balance. According to our results, mannitol is excreted to the growth medium in appreciable amounts along with other fermentation products such as glycerol and ethanol but unlike the latter metabolites mannitol production increases with temperature. We used comparative genomics to find genes involved in mannitol metabolism and established the mannitol biosynthesis pathway in W/S-clade species Starmerella bombicola using molecular genetics tools. Surprisingly, mannitol production seems to be so important that St. bombicola (and other W/S-clade species) deploys a novel pathway to mediate the conversion of glucose to fructose, thereby allowing cells to produce mannitol even when glucose is the sole carbon source. Using targeted mutations and 13C-labeled glucose followed by NMR analysis of end-products, we showed that the novel mannitol biosynthesis pathway involves fructose-6-phosphate as an intermediate, implying a key role for a yet unknown fructose-6-P phosphatase. We hypothesize that mannitol production contributed to mitigate the negative effects on redox balance of the ancient loss of alcoholic fermentation in the W/S clade. Presently, mannitol also seems to play a role in stress protection.info:eu-repo/semantics/publishedVersio
