    .E-sports games can drive the sports industry forward and sponsorship is the best way to engage consumers of this new sport. The purpose of this study is to examine the effect of sponsorship image and consumer participation in co-creation consumption activities on fans’ sponsorship response (represented by the variables interest, purchase intention and word of mouth) in e-sports. Four antecedent variables build sponsorship image (i.e., ubiquity of sport, sincerity of sponsor, attitude to sponsor and team identification). A quantitative approach is used for the purposes of this study. Some 445 questionnaires were filled in by fans who watch e-sports in Spain; these are analyzed using partial least squares structural equation modeling (PLS-SEM). The outcomes show that sponsor antecedents are crucial factors if a sponsor wants to change their sponsorship image and influence sponsorship response, and that it is also possible to use participation to improve responsesS

    Background: Women experiencing intimate partner violence are at a heightened risk of negative perinatal and breastfeeding outcomes. This study explored the experiences of accessing breastfeeding support for women who endorse a history of intimate partner violence. A study of five in-depth semi-structured interviews were completed at 12-weeks postpartum with breastfeeding mothers with a history of intimate partner violence. Findings: Women expressed difficulties in accessing a healthcare provider who had specialized skill in breastfeeding support. Trust in their healthcare provider, built through displays of compassion and competence, was important to mitigate obstacles experienced during care access for this population. Trauma-and-violence-informed care principles were beneficial to the development of the therapeutic relationship in perinatal care. Women placed value on breastfeeding support received from both healthcare providers and social supports, which impacted mothers’ perceived breastfeeding support and self-efficacy. Further, mothers described increased levels of breastfeeding self-efficacy after engaging in a trauma-and-violence-informed care program aimed at supporting breastfeeding. Conclusions: Trauma-informed care may aid in the development of trust in the therapeutic relationship, which in turn impacts access to breastfeeding support and breastfeeding self-efficacy. The inclusion of trauma-and-violence informed principles in perinatal care may be effective at mitigating barriers to access for women who endorse a history of intimate partner violence. health care on how to employ trauma-informed breastfeeding care to may lead to better support for this population

    Discomfort and pressure-related tissue injury to the buttocks are common complaints among rowers. The soft tissues of the buttocks are non-uniformly loaded during rowing. The current state of literature on seating discomfort is inconclusive as to a desirable body-seat interface pressure pattern. The purpose of this study was to determine whether localising pressure under bony protuberances or diffusing pressure over soft tissues would result in the least amount of discomfort. Force sensing arrays were used to measure body-seat interface pressures in 11 elite female rowers during rowing. Peak pressure measures were identified and pressure gradients were calculated. Discomfort was quantified using a questionnaire, and pressure data were then correlated with discomfort scores.Discomfort was weakly correlated with each of maximal pressure gradient (r=0.45) and peak pressure (r=0.43). The findings indicate pressure should be redistributed in order to avoid concentrating pressure under the bony protuberances o f the buttocks

    Exploring the effects of spinal cord stimulation for freezing of gait in parkinsonian patients

    Dopaminergic replacement therapies (e.g. levodopa) provide limited to no response for axial motor symptoms including gait dysfunction and freezing of gait (FOG) in Parkinson’s disease (PD) and Richardson’s syndrome progressive supranuclear palsy (PSP-RS) patients. Dopaminergic-resistant FOG may be a sensorimotor processing issue that does not involve basal ganglia (nigrostriatal) impairment. Recent studies suggest that spinal cord stimulation (SCS) has positive yet variable effects for dopaminergic-resistant gait and FOG in parkinsonian patients. Further studies investigating the mechanism of SCS, optimal stimulation parameters, and longevity of effects for alleviating FOG are warranted. The hypothesis of the research described in this thesis is that mid-thoracic, dorsal SCS effectively reduces FOG by modulating the sensory processing system in gait and may have a dopaminergic effect in individuals with FOG. The primary objective was to understand the relationship between FOG reduction, improvements in upper limb visual-motor performance, modulation of cortical activity and striatal dopaminergic innervation in 7 PD participants. FOG reduction was associated with changes in upper limb reaction time, speed and accuracy measured using robotic target reaching choice tasks. Modulation of resting-state, sensorimotor cortical activity, recorded using electroencephalography, was significantly associated with FOG reduction while participants were OFF-levodopa. Thus, SCS may alleviate FOG by modulating cortical activity associated with motor planning and sensory perception. Changes to striatal dopaminergic innervation, measured using a dopamine transporter marker, were associated with visual-motor performance improvements. Axial and appendicular motor features may be mediated by non-dopaminergic and dopaminergic pathways, respectively. The secondary objective was to demonstrate the short- and long-term effects of SCS for alleviating dopaminergic-resistant FOG and gait dysfunction in 5 PD and 3 PSP-RS participants without back/leg pain. SCS programming was individualized based on which setting best improved gait and/or FOG responses per participant using objective gait analysis. Significant improvements in stride velocity, step length and reduced FOG frequency were observed in all PD participants with up to 3-years of SCS. Similar gait and FOG improvements were observed in all PSP-RS participants up to 6-months. SCS is a promising therapeutic option for parkinsonian patients with FOG by possibly influencing cortical and subcortical structures involved in locomotion physiology

    Identification of Hindbrain Neural Substrates for Motor Initiation in the hatchling Xenopus laevis Tadpole

    Animal survival profoundly depends on the ability to detect stimuli in the environment, process them and respond accordingly. In this respect, motor responses to a sensory stimulation evolved into a variety of coordinated movements, which involve the control of brain centres over spinal locomotor circuits. The hatchling Xenopus tadpole, even in its embryonic stage, is able to detect external sensory information and to swim away if the stimulus is considered noxious. To do so, the tadpole relies on well-known ascending sensory pathway, which carries the sensory information to the brain. When the stimulus is strong enough, descending interneurons are activated, leading to the excitation of spinal CPG neurons, which causes the undulatory movement of swimming. However, the activation of descending interneurons that marks the initiation of motor response appears after a long delay from the sensory stimulation. Furthermore, the long-latency response is variable in time, as observed in the slow-summating excitation measured in descending interneurons. These two features, i.e. long-latency and variability, cannot be explained by the firing time and pattern of the ascending sensory pathway of the Xenopus tadpole. Therefore, a novel neuronal population has been proposed to lie in the hindbrain of the tadpole, and being able to 'hold' the sensory information, thus accounting for the long and variable delay of swim initiation. In this work, the role of the hindbrain in the maintenance of the long and variable response to trunk skin stimulation is investigated in the Xenopustadpole at developmental stage 37/38. A multifaceted approach has been used to unravel the neuronal mechanisms underlying the delayed motor response, including behavioural experiments, electrophysiology analysis of fictive swimming, hindbrain extracellular recordings and imaging experiments. Two novel neuronal populations have been identified in the tadpole's hindbrain, which exhibit activation patterns compatible with the role of delaying the excitation of the spinal locomotor circuit. Future work on cellular properties and synaptic connections of these newly discovered populations might shed light on the mechanism of descending control active at embryonic stage. Identifying supraspinal neuronal populations in an embryonic organism could aid in understanding mechanisms of descending motor control in more complex vertebrates

    The purpose of this study is to investigate the use of video-game technology in the design and implementation of interactive sonic centric artworks, the purpose of which is to create and contribute to the discourse and understanding of its effectiveness in electro-acoustic composition highlighting the creative process. Key research questions include: How can the language of electro-acoustic music be placed in a new framework derived from videogame aesthetics and technology? What new creative processes need to be considered when using this medium? Moreover, what aspects of 'play' should be considered when designing the systems? The findings of this study assert that composers and sonic art practitioners need little or no coding knowledge to create exciting applications and the myriad of options available to the composer when using video-game technology is limited only by imagination. Through a cyclic process of planning, building, testing and playing these applications the project revealed advantages and unique sonic opportunities in comparison to other sonic art installations. A portfolio of selected original compositions, both fixed and open are presented by the author to complement this study. The commentary serves to place the work in context with other practitioners in the field and to provide compositional approaches that have been taken

    Balancing the urban stomach: public health, food selling and consumption in London, c. 1558-1640

    Until recently, public health histories have been predominantly shaped by medical and scientific perspectives, to the neglect of their wider social, economic and political contexts. These medically-minded studies have tended to present broad, sweeping narratives of health policy's explicit successes or failures, often focusing on extraordinary periods of epidemic disease viewed from a national context. This approach is problematic, particularly in studies of public health practice prior to 1800. Before the rise of modern scientific medicine, public health policies were more often influenced by shared social, cultural, economic and religious values which favoured maintaining hierarchy, stability and concern for 'the common good'. These values have frequently been overlooked by modern researchers. This has yielded pessimistic assessments of contemporary sanitation, implying that local authorities did not care about or prioritise the health of populations. Overly medicalised perspectives have further restricted historians' investigation and use of source material, their interpretation of multifaceted and sometimes contested cultural practices such as fasting, and their examination of habitual - and not just extraordinary - health actions. These perspectives have encouraged a focus on reactive - rather than preventative - measures. This thesis contributes to a growing body of research that expands our restrictive understandings of pre-modern public health. It focuses on how public health practices were regulated, monitored and expanded in later Tudor and early Stuart London, with a particular focus on consumption and food-selling. Acknowledging the fundamental public health value of maintaining urban foodways, it investigates how contemporaries sought to manage consumption, food production waste, and vending practices in the early modern City's wards and parishes. It delineates the practical and political distinctions between food and medicine, broadly investigates the activities, reputations of and correlations between London's guild and itinerant food vendors and licensed and irregular medical practitioners, traces the directions in which different kinds of public health policy filtered up or down, and explores how policies were enacted at a national and local level. Finally, it compares and contrasts habitual and extraordinary public health regulations, with a particular focus on how perceptions of and actual food shortages, paired with the omnipresent threat of disease, impacted broader aspects of civic life

    Structural and Attitudinal Barriers to Bicycle Ownership and Cycle-Based Transport in Gauteng, South Africa

    Policies that aim to facilitate and promote non-motorised transport (NMT), and in particular cycling, have been developed by many high-income countries facing increasingly congested roads and saturated public transport systems. Such policies are also emerging in many low- and middle-income settings where high rates of urbanisation have led to similar problems with motorised transport. The aim of the present study was to better understand the potential structural and attitudinal barriers to cycle-based transport in one such context: South Africa’s Gauteng Province, the industrial powerhouse of sub-Saharan Africa that has recently made a firm commitment to NMT. The study focussed on demographic and socioeconomic variation in bicycle and car ownership, and related this to: (1) the reported use of motorised and non-motorised transport (both private and public); and (2) perceived ‘problems’ with cycling. The analyses drew on interviews with key respondents from n = 27,490 households conducted in 2013 as part of the third Quality of Life survey undertaken by the Gauteng City Regional Observatory. The survey contained items on three outcomes of interest: household vehicle ownership (bicycles and cars); modes of transport used for the “trips” most often made; and respondents’ “single biggest problem with… cycling”. Respondent- and household-level demographic and socioeconomic determinants of these outcomes were examined using descriptive and multivariable statistical analyses, the latter after adjustment for measured potential confounders identified using a theoretical causal path diagram (in the form of a directed acyclic graph). Of the n = 26,469 households providing complete data on all of the variables examined in the present study, only n = 8722 (32.9%) owned a car and fewer still (n = 2244; 8.4%) owned a bicycle. The ownership of these assets was commonest amongst wealthier, economically active households; and those that owned a car had over five times the odds of also owning a bicycle, even after adjustment for potential confounding (OR 5.17; 95% CI 4.58, 5.85). Moreover, of household respondents who reported making ‘trips’ during the preceding month (n = 18,209), over two-thirds of those whose households owned a car (70.1%) reported private car-based transport for such trips, while only 3.2% of those owning a bicycle reported cycling. Amongst the specific responses given to the item requesting the “single biggest problem with… cycling” by far the commonest was “Don’t know how to cycle” (32.2%), less than half as many citing “Vehicle accident risk” (15.9%), and fewer still: “Destination is too far” (13.9%); “Crime” (10.3%); “Too much effort” (9.2%); or “Lack of good paths” (4.6%). While the first of these reasons was commonest amongst poorer households, concerns about risk and effort were both most common amongst better educated, economically active and wealthier/better serviced households. In contrast, concerns over (cycle) paths were only common amongst those owning bicycles. The low prevalence of household bicycle ownership, and the disproportionate number of households owning bicycles that also owned cars, might explain the very small proportion of the ‘the trips most often made’ that involved cycle-based transport (0.3%), and the preferential use of cars amongst households owning both bicycles and cars. Low levels of bicycle ownership might also explain why so many respondents cited “Don’t know how” as the “single biggest problem with… cycling”; although risk and effort were also substantial concerns (presumably for many who did, and some who did not, know how to cycle); the lack of suitable cycle lanes being only primarily a concern for those who actually owned bicycles. Structural and attitudinal barriers to cycle-based transport limit the use of cycle-based transport in Gauteng, not only amongst the vast majority of household respondents who lack the means to cycle (and the means to learn how), but also amongst those dissuaded from learning to cycle, purchasing a bicycle and/or using a bicycle they own by: the risks and effort involved; the lack of suitable cycle paths; and/or because they also own a car and prefer to drive than cycle

    Metodología de intervención para trabajar ODS. Educación a través de las artes

    Get PDF
    La Agenda 2030 presenta 17 Objetivos de Desarrollo Sostenible (ODS), con sus metas e indicadores universales que los países miembros de la ONU emplean para enmarcar sus políticas. Entre las metas del ODS 4 “educación de calidad” encontramos: “asegurar que todos los alumnos adquieran los conocimientos teóricos y prácticos necesarios para promover el desarrollo sostenible, entre otras cosas mediante la educación para el desarrollo sostenible y los estilos de vida sostenibles, los derechos humanos, la igualdad de género, la promoción de una cultura de paz y no violencia, la ciudadanía mundial y la valoración de la diversidad cultural y la contribución de la cultura al desarrollo sostenible”. La educación, se considera el motor de la Agenda 2030 porque, además de representar el centro del ODS 4, desempeña también un papel notable en la implementación de los demás, mejorando su alcance y efectividad. Así pues, entre las disciplinas que sustentan este trabajo se escogió la Educación para el Desarrollo Sostenible y la Ciudadanía Global como marco de acción y punto de partida en la formación de los ciudadanos de un futuro viable, equitativo y habitable. Se continuó investigando las oportunidades del desarrollo de la Competencia Intercultural en las relaciones humanas, aquello que diferencia a unas personas de otras puede aportar al conjunto de la sociedad y cómo la educación permitiría su aprovechamiento. Con todo ello, se planteó el marco didáctico de interacción en el cual se implementó la interculturalidad en el ejercicio educativo. Se estudió así el poder de las artes como medio de motivación e inspiración a la hora de transmitir de la manera más eficaz posible los valores considerados más arriba. El objetivo del presente estudio se centra en demostrar el potencial de las artes para fomentar las competencias comunicativas, sociales, interculturales, emocionales, de ciudadanía y sostenibilidad. Para ello, se ha realizado una investigación aplicada que deriva en una propuesta concreta de intervención con un programa educativo destinado a la enseñanza de lenguas, tanto primera como extranjera, en distintos niveles de la educación formal en Mali y en España, aplicando un método holístico basado en el paradigma interpretativo. A través de la pintura, la literatura y el cine, se plantean una serie de actividades ideadas para crear un entorno educativo integrador, favorecer el empoderamiento del alumnado y promover el pensamiento crítico, la empatía, la resiliencia, la comunicación, la cooperación y la educación intercultural, como competencias esenciales para la consecución de los 17 ODS, la construcción de un mundo transcultural sostenible y el desarrollo de una ciudadanía global preparada para los retos del siglo XXI. En la metodología de este proceso educativo innovador, multidisciplinar, flexible y adaptable, se ha empleado un análisis del proceso de investigación para monitorizarlo adecuadamente (DAFO). Cada una de las propuestas presenta una recogida de datos cualitativos (observación, rúbricas) y cuantitativos (encuestas, entrevistas) y se ofrece un análisis de contraste de los resultados finales. Con todo, se espera facilitar la exigente tarea que supone hacer consciente a la sociedad de base (desde la misma infancia; desde los niveles más bajos de la misma y en todos los niveles de la educación formal) de en qué consisten los ODS y su relevancia para hacer de todas las personas corresponsables directas en su consecución para garantizar un futuro sostenible para toda la ciudadanía global.The 2030 Agenda presents 17 Sustainable Development Goals (SDGs), with their universal targets and indicators that UN member countries use to frame their policies. Among the targets of SDG 4 “quality education,” we find the one that seeks: “to ensure that all students acquire the theoretical and practical knowledge necessary to promote sustainable development, among other things through education for sustainable development and sustainable lifestyles, human rights, gender equality, the promotion of a culture of peace and non-violence, world citizenship and the appreciation of cultural diversity and the contribution of culture to sustainable development”. Education is considered the engine of the 2030 Agenda because, in addition to representing the centre of SDG 4, it also plays a notable role in the implementation of the others, improving their scope and effectiveness. Among the disciplines that support this research, Education for Sustainable Development and Global Citizenship sets the framework for action and represents a starting point in the formation of citizens for a viable, equitable and habitable future. Global citizenship implies human relations and those and intrinsically shaped by culture. Intercultural Education and, more specifically, the development of Intercultural Competence needed to be considered. What differentiates some people from others can contribute to society as a whole and education is the means to explore and understand. For the design of a didactic framework of interaction, the power of the arts was studied as a means of motivation and inspiration when transmitting the values considered above in the most effective way possible. The objective of this study focuses on proving the potential of the arts to promote communicative, social, intercultural, emotional, citizenship and sustainability skills. For this, the theoretical research derived in a concrete intervention proposal with an educational program in language teaching, both first and foreign languages, at different levels of formal education in Mali and Spain, applying a holistic method based on the interpretive paradigm. Through painting, literature and cinema, a series of activities were designed to create an inclusive educational environment, favour the empowerment of students and promote critical thinking, empathy, resilience, communication, cooperation and intercultural education, as essential skills for the achievement of the 17 SDGs, the construction of a sustainable transcultural world and the development of global citizenship prepared for the challenges of the 21st century. In the methodology of this innovative, multidisciplinary, flexible and adaptable educational process, an analysis of the research process has been used to adequately monitor it (SWOT). Each of the proposals presents a collection of qualitative data (observation, rubrics) and quantitative data (surveys, interviews) and contrast analysis of the final results is offered. All in all, it is expected to facilitate the demanding task of making basic society aware (from childhood itself, from its lowest levels and at all levels of formal education) of what the SDGs consist of and their relevance to make all people directly co-responsible in its achievement to guarantee a sustainable future for all global citizens

    Strung pieces: on the aesthetics of television fiction series

    Get PDF
    As layered and long works, television fiction series have aesthetic properties that are built over time, bit by bit. This thesis develops a group of concepts that enable the study of these properties, It argues that a series is made of strung pieces, a system of related elements. The text begins by considering this sequential form within the fields of film and television. This opening chapter defines the object and methodology of research, arguing for a non-essentialist distinction between cinema and television and against the adequacy of textual and contextual analyses as approaches to the aesthetics of these shows. It proposes instead that these programmes should be described as televisual works that can be scrutinised through aesthetic analysis. The next chapters propose a sequence of interrelated concepts. The second chapter contends that series are composed of building blocks that can be either units into which series are divided or motifs that unify series and are dispersed across their pans. These blocks are patterned according to four kinds of relations or principles of composition. Repetition and variation are treated in tandem in the third chapter because of their close connection, given that variation emerges from established repetition. Exception and progression are also discussed together in the fourth chapter since they both require a long view of these serial works. The former, in order to be recognised as a deviation from the patterns of repetition and variation. The latter, In order to be understood in Its many dimensions as the series advances. Each of these concepts is further detailed with additional distinctions between types of units, motifs, repetitions, variations, and exceptions, using illustrative examples from numerous shows. In contrast, the section on progression uses a single series as case study, Carnivàle (2003-05), because this is the overarching principle that encompasses all the others. The conclusion considers the findings of the research and suggests avenues for their application
