Questionamentos acerca de valores axiológicos no turismo: uma abordagem fenomenológica hermenêutica

The study presents the possibility of interpretation of axiological values of tourism as a practice conceived on a human being or Dasein as being-in-the-world of tourism. The value, as an object of Axiology, was considered the predictor of the human being conduct in the phenomenon reflecting this same value in tourism. The aim was to comprehend and interpret through the way of being of Dasein in tourism, which axiological values are chosen to the practice of tourism and the intentional feelings directed to these values. A phenomenological hermeneutics research with exploratory characteristics was accomplished in order to survey the values. Ten episodic interviews were conducted from the hermeneutic situation - constituted by fore-having, fore-sight and fore-conception of each Dasein interviewed, by adopting a sympathetic conduct and sympathy of Max Scheler and the use of emotional intuition to capture the intentional feelings, interpreted afterwards by the analysis of a Martin Heidegger's phenomenology in Being and Time. The results showed that, even without categorisation, the totality of the living experiences, the way of being of positive values outnumber the negatives ones in the existence of each Dasein, leading them to the Learning, which are comprising: experiences to provide self-knowledge, historical-cultural values, and memory as part of the learning experiences, hospitality as a way of openness and socio-cultural exchange, solidarity and peace. Intentional feelings directed at the values for the choice for practicing tourism were: love, happiness, pleasure, respect and trust. Four evidences were found concerning the use of sentimental perspective and intentional feeling of Scheler and regarding the logic of the heart of Pascal used by this author. The sociocultural interrelationships and exchanges form the basis for developing tourism as phenomenon. Therefore the character being-with or Mitsein is prevalent in tourism activities. Despite the learning was the purpose of the experiences, the ultimate goal was the improvement and personal enrichment of Dasein´s humanity development. The study also showed the hermeneutic phenomenological seeing opens the access of the living experiences of values, without making arbitrarily judgment and achieve "to the thing themselves", which, by the overlapping of categories, dispositions and intentional feelings, form the evaluative experiences and are possible to access through the fundamental ontology of Heidegger. The study contributes to broaden the vision concerning to the totality of tourism and the practitioners Dasein of it. As possibilities for deepening studies, was pointed out: the total person of Scheler; the care or Sorge as a form of love in Heidegger; happiness and pleasure in the practice of tourism and human flourishing or eudaimonia.

Desire and Divorce in Serglige Con Culainn

This paper examines the expression of ideas about love, marriage and divorce in Serglige Con Culainn. It is argued that the two versions of the tale, both of which are incomplete, exhibit distinctive approaches to love and the portrayal of the female characters. The earlier recension depicts male desire as a violent attack by Otherworld women that renders the man incapacitated. The later version provides a radically different view, offering a strikingly sympathetic portrait of the two female protagonists which may suggest a female audience. This version gives a remarkable insight into sexual mores and marital breakdown in a protracted and detailed negotiation involving the three main characters. It reveals tensions between male and female views of marriage and particularly of the practice of concubinage. It values loyalty between married partners over the fulfilment of desire and demonstrates the enduring and destructive effects of passion which are healed here only through magical interventions.

Crossing the Threshold: Mysticism, Liminality, and Remedios Varo’s Bordando el manto terrestre (1961–2)

In this article we propose to take up the question of the painter’s work in connection with liminality more explicitly. We will argue that the limen Varo’s heroines cross is a psychological one that takes them through a process culminating in a rebirth of the self, and that to the extent they are in-between identities and involved in a process of initiation, they can be considered liminars (Turner). We will also argue that in order to develop this theme, which culminates in her most autobiographical work, the triptych Bordando el manto terrestre (1961–2), the artist needed to find a way conceptually to bridge surrealism and her interest in mysticism. She would have found a sympathetic approach in Jung, one of the founders of psychoanalysis, who turned explicitly to the question of religion in the troubled thirties, though, as we shall see, she revised his androcentric approach. We will suggest that Jung’s writing helped the artist make a transition from surrealism to esoteric spirituality.

Humankindness: Illness, Animality, and the Limits of the Human in the Victorian Novel

This project posits a link between representations of animals or animality and representations of illness in the Victorian novel, and examines the narrative uses and ideological consequences of such representations. Figurations of animality and illness in Victorian fiction have been examined extensively as distinct phenomena, but examining their connection allows for a more complex view of the role of sympathy in the Victorian novel. The commonplace in novel criticism is that Victorian authors, whether effectively or not, constructed their novels with a view to the expansion of sympathy. This dissertation intervenes in the discussion of the Victorian novel as a vehicle for sympathy by positing that texts and scenes in which representations of illness and animality are conjoined reveal where the novel draws the boundaries of the human, and the often surprising limits it sets on sympathetic feeling. In such moments, textual cues train or direct readerly sympathies in ways that suggest a particular definition of the human, but that direction of sympathy is not always towards an enlarged sympathy, or an enlarged definition of the human. There is an equally (and increasingly) powerful antipathetic impulse in many of these texts, which estranges readerly sympathy from putatively deviant, degenerate, or dangerous groups. These two opposing impulses—the sympathetic and the antipathetic—often coexist in the same novel or even the same scene, creating an ideological and affective friction, and both draw on the same tropes of illness and animality. Examining the intersection of these different discourses—sympathy, illness, and animality-- in these novels reveals the way that major Victorian debates about human nature, evolution and degeneration, and moral responsibility shaped the novels of the era as vehicles for both antipathy and sympathy. Focusing on the novels of the Brontës and Thomas Hardy, this dissertation examines in depth the interconnected ways that representations of animals and animality and representations of illness function in the Victorian novel, as they allow authors to explore or redefine the boundary between the human and the non-human, the boundary between sympathy and antipathy, and the limits of sympathy itself.

Haematidrosis: The Rare Phenomenon of Sweating Blood

Objectives: Haematidrosis, also known as haematohidrosis, is a very rare condition where blood is excreted with sweat. As only a few cases have been described in the literature, we present guidelines on management of this rare phenomenon. Case: A 44-year-old man presented with self-limited and spontaneous bleeding episodes from different parts of his body. This had started 2 weeks before admission after an episode of extreme emotional stress. Medical history and laboratory tests were normal. The microscopic examination of a sample of the fluid excreted confirmed all blood elements. Conclusion: The disorder is thought to be related to activation of the sympathetic nervous system. The use of benzodiazepines and beta blockers may be helpful in controlling the bleeding episodes and give some comfort to the patient.

Long distance coupling of a quantum mechanical oscillator to the internal states of an atomic ensemble

We propose and investigate a hybrid optomechanical system consisting of a micro-mechanical oscillator coupled to the internal states of a distant ensemble of atoms. The interaction between the systems is mediated by a light field which allows the coupling of the two systems in a modular way over long distances. Coupling to internal degrees of freedom of atoms opens up the possibility to employ high-frequency mechanical resonators in the MHz to GHz regime, such as optomechanical crystal structures, and to benefit from the rich toolbox of quantum control over internal atomic states. Previous schemes involving atomic motional states are rather limited in both of these aspects. We derive a full quantum model for the effective coupling including the main sources of decoherence. As an application we show that sympathetic ground-state cooling and strong coupling between the two systems is possible.

Beyond orientalism: 'The Stranger' and 'Colonial Cosmopolitanism' in the romantic period novel

Going beyond Orientalism in its examination of novels dealing with British colonisation in the West, as well as the East Indies, the postcolonial frame of my thesis develops recent theorisations of the Romantic ‘stranger’. Analysing a range of novels from the much anthologised Mansfield Park (1814), to less well-known narratives such as John Thelwall’s The Daughter of Adoption (1801) and Sir Walter Scott’s Saint Ronan’s Well (1823), my thesis seeks to account for a model of ‘colonial cosmopolitanism’ within fiction of the period. Considering the cosmopolitan dimensions of the transferential rhetoric of slavery, my thesis explores the ways in which, Jane Austen, Amelia Opie and Maria Edgeworth consider the position of women in domestic society through a West Indian frame. Demonstrating the need for reform both at home and abroad, such novels are representative of a fledgling cosmopolitanism that is often overlooked in current criticism. In seeking to account for ‘colonial cosmopolitanism’ as a new model for reading fiction composed during the Romantic period, my thesis attempts to add further nuance to current understandings of sympathetic exchange during the process of British colonisation. In chapters four and five I will develop my analysis of novels dealing with colonial expansion in the Caribbean to consider novels which deal with the Indian subcontinent. Although stopping short of questioning colonial expansion, discourses of ‘colonial cosmopolitanism’, as my thesis demonstrates, provided a foundation for humanitarian and cultural engagement which was mutually transformative for both the coloniser and the colonised.

European Cosmopolitanism and Civil Society

The discussion of European cosmopolitanism and civil society has failed to take questions of culture seriously enough. While remaining sympathetic to liberal forms of cosmopolitanism, this article considers the view that such proposals fail to make space for the 'Other'. In the context of histories of nationalist violence, masculinism and consumerism this article discusses the charge that ideas of European civilization need to be reconsidered. In the final part of the article, I discuss the view that cultural feminism and certain versions of multiculturalism have much to contribute towards the European project. However, at this point, I seek to distance myself from essentialist arguments in respect of identity. A generative European cosmopolitanism would do well to take questions of cultural domination seriously without reducing the complexity of modern identities.

A randomised controlled trial comparing weight adjusted dose versus fixed dose prophylactic phenylephrine infusion on maintaining systolic blood pressure during caesarean section under spinal anaesthesia.

Background: Spinal anaesthesia is the standard of care for elective caesarean delivery. It has advantages over general anaesthesia. However the sympathetic blockade induced by spinal anaesthesia results in an 80 percent incidence of hypotension without prophylactic management. Current evidence supports co-loading with intravenous fluids in conjunction with the use of vasopressors as the most effective way to prevent and treat the hypotension. Phenylephrine is the accepted vasopressor of choice in the parturient. A prophylactic phenylephrine infusion combined with a fluid co-load is proven to be an effective and safe method of maintaining maternal hemodynamic stability. While most published studies have assessed the effectiveness of a prophylactic phenylephrine fixed dose infusion, few studies have assessed the effect of a prophylactic phenylephrine weight adjusted dose infusion on maintaining maternal hemodynamic stability following spinal anesthesia for a cesarean delivery. Objective: To compare the incidence of hypotension between women undergoing elective caesarean section under spinal anaesthesia, receiving prophylactic phenylephrine infusion at a fixed dose of 37.5 micrograms per minute versus a weight adjusted dose of 0.5 micrograms per kilogram per minute. Methods: One hundred and eight patients scheduled for non-urgent caesarean section under spinal anaesthesia were randomized into 2 groups; control group and intervention group using a computer generated table of numbers. Control group; Received prophylactic phenylephrine fixed dose infusion at 37.5 micrograms per minute. Intervention group; Received prophylactic phenylephrine weight adjusted dose infusion at 0.5 micrograms per kilogram per minute Results: The two groups had similar baseline characteristics in terms of ; Age, sex, weight and height. There was a 35.2% incidence of hypotension in the fixed dose group and an 18.6% incidence of hypotension in the weight adjusted dose group. This difference was found to be of borderline statistical significance p-value 0.05, and the difference in the incidence rates between the two groups was found to be statistically significant p= 0.03. The difference in the incidence of reactive hypertension and bradycardia between the two groups was not statistically significant: p-value of 0.19 for reactive hypertension and p-value of 0.42 for the incidence of bradycardia. There was also no statistically significant difference in the use of phenylephrine boluses, use of atropine, intravenous fluid used and the number of times the infusion was stopped. Conclusion: Among this population, the incidence of hypotension was significantly less in the weight adjusted dose group than in the fixed dose group. There was no difference in the number of physician interventions required to keep the blood pressure within 20% of baseline, and no difference in the proportion of reactive hypertension or bradycardia between the two groups. Administering prophylactic phenylephrine infusion at a weight adjusted dose of 0.5 micrograms per kilogram per minute results in a lower incidence of hypotension compared to its administration at a fixed dose of 37.5 micrograms per minute.

THE INFLUENCE OF MOTIVATION ON EMOTION REGULATION AND MOTOR PERFORMANCE: EXAMINATION OF A NEURO-AFFECTIVE MODEL

Mental stress is known to disrupt the execution of motor performance and can lead to decrements in the quality of performance, however, individuals have shown significant differences regarding how fast and well they can perform a skilled task according to how well they can manage stress and emotion. The purpose of this study was to advance our understanding of how the brain modulates emotional reactivity under different motivational states to achieve differential performance in a target shooting task that requires precision visuomotor coordination. In order to study the interactions in emotion regulatory brain areas (i.e. the ventral striatum, amygdala, prefrontal cortex) and the autonomic nervous system, reward and punishment interventions were employed and the resulting behavioral and physiological responses contrasted to observe the changes in shooting performance (i.e. shooting accuracy and stability of aim) and neuro-cognitive processes (i.e. cognitive load and reserve) during the shooting task. Thirty-five participants, aged 18 to 38 years, from the Reserve Officers’ Training Corp (ROTC) at the University of Maryland were recruited to take 30 shots at a bullseye target in three different experimental conditions. In the reward condition, $1 was added to their total balance for every 10-point shot. In the punishment condition, $1 was deducted from their total balance if they did not hit the 10-point area. In the neutral condition, no money was added or deducted from their total balance. When in the reward condition, which was reportedly most enjoyable and least stressful of the conditions, heart rate variability was found to be positively related to shooting scores, inversely related to variability in shooting performance and positively related to alpha power (i.e. less activation) in the left temporal region. In the punishment (and most stressful) condition, an increase in sympathetic response (i.e. increased LF/HF ratio) was positively related to jerking movements as well as variability of placement (on the target) in the shots taken. This, coupled with error monitoring activity in the anterior cingulate cortex, suggests evaluation of self-efficacy might be driving arousal regulation, thus affecting shooting performance. Better performers showed variable, increasing high-alpha power in the temporal region during the aiming period towards taking the shot which could indicate an adaptive strategy of engagement. They also showed lower coherence during hit shots than missed shots which was coupled with reduced jerking movements and better precision and accuracy. Frontal asymmetry measures revealed possible influence of the prefrontal lobe in driving this effect in reward and neutral conditions. The possible interactions, reasons behind these findings and implications are discussed.

Biological indicators of stress in pacu (Piaractus mesopotamicus) after capture

Os efeitos da captura (perseguição, contenção em puçá e exposição aérea) no perfil sanguíneo do cortisol, glicose, cloreto, sódio, potássio, cálcio e na osmolaridade, hematócrito, hemoglobina, número de células vermelhas (CV) e volume corpuscular médio (VCM) foram investigados no pacu (Piaractus mesopotamicus). Um total de 132 peixes (49,7 ± 11,7 g) foi submetido à captura com 3 ou 5 minutos de exposição aérea. Nove peixes de cada tratamento foram amostrados 5, 15, 30, 60 minutos e 24 horas depois e outros nove peixes foram amostrados antes da captura e considerados controle. A captura resultou em aumento do cortisol e glicose no sangue 30 e 5 minutos depois da captura, respectivamente, independente do tempo de exposição aérea. Ambos os indicadores recuperaram os valores controle em 24 horas. Nos dois grupos de peixes, o cloreto plasmático diminuiu 60 minutos após captura e não recuperou os valores controle, enquanto o sódio sérico aumentou entre 15 e 30 minutos recuperando a condição controle em 24 horas. Não houve alteração significativa nos valores de potássio, cálcio, osmolaridade ou no hematócrito, hemoglobina, CV e VCM como consequência da captura. Os estressores sequenciais aplicados no pacu durante a captura ativaram o eixo cérebro-pituitária-interrenal (respostas do cortisol e glicose), mas a ativação do eixo cérebro-sistema simpático-células cromafins foi aparentemente moderada (respostas iônicas e hematológicas).

Central proopiomelanocortin but not neuropeptide Y mediates sympathoexcitation and hypertension in fat fed conscious rabbits

OBJECTIVE: High-fat diet (HFD)-induced hypertension in rabbits is neurogenic because of the central sympathoexcitatory actions of leptin. Hypothalamic melanocortin and neuropeptide Y (NPY) neurons are recognized as the major signalling pathways through which leptin exerts its central effects. In this study, we assessed the effects of specific antagonists and agonists to melanocortin and NPY receptors on HFD-induced sympathoexcitation and hypertension. METHODS: Rabbits were instrumented with intracerebroventricular cannula, renal sympathetic nerve activity (RSNA) electrode, and blood pressure telemetry transmitter. RESULTS: After 3 weeks HFD (13.5% fat, n = 12) conscious rabbits had higher RSNA (+3.8  nu, P = 0.02), blood pressure (+8.6  mmHg, P < 0.001) and heart rate (+15  b/min, P = 0.01), and brain-derived neurotrophic factor levels in the hypothalamus compared with rabbits fed a control diet (4.2% fat, n = 11). Intracerebroventricular administration of the melanocortin receptor antagonist SHU9119 reduced RSNA (-2.7  nu) and blood pressure (-8.5  mmHg) in HFD but not control rabbits, thus reversing 100% of the hypertension and 70% of the sympathoexcitation induced by a HFD. By contrast, blocking central NPY Y1 receptors with BVD10 increased RSNA only in HFD rabbits. Intracerebroventricular α-melanocortin stimulating hormone increased RSNA and heart rate (P < 0.001) in HFD rabbits but had no effect in control rabbits. CONCLUSION: These findings suggest that obesity-induced hypertension and increased RSNA are dependent on the balance between greater activation of melanocortin signalling through melanocortin receptors and lesser activation of NPY sympathoinhibitory signalling. The amplification of the sympathoexcitatory effects of α-melanocortin stimulating hormone also indicates that the underlying mechanism is related to facilitation of leptin-melanocortin signalling, possibly involving chronic activation of brain-derived neurotrophic factor.

Tone entropy analysis of foetal heart rate variability

Development of the foetal autonomic nervous system can be indirectly understood by looking at the changes in beat to beat variability in foetal heart rates. This study presents Tone-Entropy (T-E) analysis of foetal heart rate variability (HRV) at multiple lags (1–8) to understand the influence of gestational ages (early and late) on the development of the foetal autonomic nervous system (ANS). The analysis was based on foetal electrocardiograms (FECGs) of 46 healthy foetuses of 20–32 weeks (early group) and 22 foetuses of 35–41 weeks (late group). Tone represents sympatho-vagal balance and entropy the total autonomic activities. Results show that tone increases and entropy decreases at all lags for the late foetus group. On the other hand, tone decreases and entropy increases at lags 1–4 in the early foetus group. Increasing tone in late foetuses might represent significant maturation of sympathetic nervous systems because foetuses approaching to delivery period need increased sympathetic activity. T-E could be quantitative clinical index to determine the early foetuses from late ones on the basis of maturation of autonomic nervous system.

Book review: Review of 'W. E. H. Stanner, The dreaming and other essays' with an introduction by Robert Manne. Melbourne: Black Inc. Agenda, 2009. ISBN: 9781863955171, (Pb) 336 pp. $AUD32.95

There is no more imposing figure in the history of Australian anthropology than W.E.H. ('Bill') Stanner (1905-1981). While some of his contemporaries produced more ethnography, none matched his skill and eloquence in describing the life-worlds of Aboriginal people. While others of his age were just as closely involved in arguing for the defensibility of Aboriginal society, none did so with such convincing passion. With these two legacies in mind, anthropologists in the here and now would be hard put to describe Stanner's oeuvre in either/or terms. He is best remembered for his scintillating, sympathetic analyses of Aboriginal myth, ritual and local organisation, together with his trenchant critiques of Durkheim and Freud.

Impedancias basales registradas durante la denervación renal por radiofrecuencia en pacientes con hipertensión arterial resistente

Objetivo: Determinar diferencias en las impedancias basales registradas durante los procedimientos de denervación renal por radiofrecuencia de los pacientes sometidos a este procedimiento en la Fundación Cardioinfantil de Bogotá durante los años 2012 a 2015. Materiales y métodos: Estudio observacional, analítico de corte retrospectivo, donde se analizaron todas las impedancias basales medidas durante los procedimientos de denervación renal, buscando diferencias significativas entre los segmentos de las arterias intervenidas, estratificados en proximal, medio distal y superior, lateral, inferior u ostial. Con seguimiento a los pacientes a tres, seis y doce meses en cuanto a presión arterial de consultorio. Resultados: Se evaluaron 150 puntos de denervación renal exitosos, correspondientes a 23 arterias renales de 11 procedimientos. La mediana de edad fue 56 años. Al realizar un modelo de regresión lineal no se encontró ninguna diferencia estadísticamente significativa entre las impedancias de ninguno de los segmentos de las arterias ni sitios anatómicos. Se documentó disminución de presión arterial sistólica a tres meses, seis meses y doce meses de 14 mmHg (RIQ 10-33mmHg), 21 mmHg (RIQ 12-42mmHg) y 19 mmHg (RIQ 11-42 mmHg) respectivamente
