Les représentations de la ruralité dans les films de fiction français du début des années 1990 au début des années 2010 : permanences et changements / Representations of rurality in French fiction films from the beginning of the 1990's to the beginning of the 2010's : permanence and change

Asté, Maylis 04 October 2018 (has links)
À partir de l'étude d'un corpus de films de fiction sortis en salles entre 1990 et 2012 et dont l'action est située dans les campagnes françaises contemporaines, cette thèse analyse la construction des représentations de la ruralité française sous l'angle des tensions entre permanence et changements.En nous attachant à éclairer la démarche des cinéastes qui ont fait le choix d'ancrer leur récit dans les campagnes, nous questionnons l'influence de ce choix sur les techniques de narration, la mise en scène ou encore la distribution. Vivants portraits, les films sont autant de définitions de campagnes idéelles et sensibles. Que voit-on et qui voit-on dans ces films ? Que font les personnages et que disent-ils ? Comment vivent-ils ? Peut-on parler d'une école ou d'un courant durant cette période charnière ? À la force toujours opératoire d'anciens stéréotypes urbanocentrés répond le désir de certains cinéastes de décentrer les regards, pour explorer une géographie humaine. / This thesis analyzes the construction of French rurality's representations in terms of tensions between permanency and change, on the basis of a corpus of fiction films released between 1990 et 2012, which narration takes place in contemporary French countryside. By actively shedding light on the approach of the filmmakers who decided to root their films in the countryside, we question the way this decision impacts narrative techniques, directing or even casting. Films being living portraits, each one is a definition of the countryside, ideal or sensitive. What, and who do we see in those films? What do the characters do and what do they say? How do they live? Can we talk of a “school” or a “wave” defining this pivotal period? Despite the enduring power of old urban-centric stereotypes, these directors are set on off-centering the points of view to explore a human geography.

The Restorative Effects of Pulsed Infrared Light Therapy on Significant Loss of Peripheral Protective Sensation in Patients With Long-Term Type 1 and Type 2 Diabetes Mellitus

Arnall, D., Nelson, A. G., López, L., Sanz, N., Iversen, L., Sanz, I., Stambaugh, L., Arnall, S. B. 01 May 2006 (has links)
Pulsed infrared light therapy (PILT) has been shown to increase peripheral sensation in diabetic patients with diabetic peripheral neuropathy (DPN). However, most studies last for very short periods, with the subjects receiving only 6-20 treatments. The purpose of this study was to evaluate the effectiveness of an eight-week course of PILT in reversing long-standing, profound DPN in patients with type 1 and type 2 diabetes. Twenty-two subjects with a diagnosis of type 1 (n=2) or type 2 (n=20) diabetes participated in the study. PILT was administered to one foot chosen at random with the other foot serving as a within-subject control (no treatment). Patients underwent 24 treatments (3 times/week, for eight weeks) for 30 min per treatment. Changes in peripheral protective sensation (PPS) were measured using Semmes-Weinstein monofilaments (SWM) ranging from 3.7 to 6.48. PILT improved PPS even in patients with long-standing chronic neuropathies whose initial pre-study sensation was not measurable with a 200-g SWM. PILT significantly improves PPS. While the exact mechanism of action is not understood, infrared light may improve peripheral neuropathies by improving foot perfusion by stimulating nitric oxide production.

Gender as moderator of the relationship between impulsivity and driving after cannabis use

Wang, Yifan 05 1900 (has links)
Road traffic crashes are a serious public health problem worldwide, and human factors are the most prominent factor of accidents, affecting mostly the young adults. Past studies found that both gender and personality traits such as impulsivity are associated with risky driving, however, the interaction of these predictors is rarely addressed in the literature. To bridge the gap, the present study explores how a specific facet of impulsivity interacts with our hypothesized moderator, gender identification, leads to drug driving using a moderator analysis. We recruited participants from 17 to 35 years old possessing a valid drivers' licence via Facebook advertising. They were invited to complete a questionnaire on their socio-demographic characteristics, cannabis consumption habits and impulsivity scores. A moderator analysis is conducted to disentangle the relationship between sensation seeking, gender and driving after cannabis consumption using SPSS Process. The proposed model contains sensation seeking as an exogenous variable directly associated with driving after cannabis use, and this relationship is moderated by gender identification. The current study provides evidence that sensation seeking and gender identification are not only associated with DACU but also interact to affect driving behaviour. Implications of the study are discussed. / Les accidents routiers constituent de graves problèmes de santé publique dans le monde et les facteurs humains sont connus pour être le principal facteur d'accidents, impliquant principalement les jeunes adultes. Des études antérieures ont démontré que le genre ainsi que des facteurs liés à la personnalité tels que l'impulsivité sont associés à la conduite après consommation récente de cannabis, cependant, l'interaction de ces prédicteurs est rarement abordée dans la littérature. Pour cette raison, cette étude vise à explorer le processus par lequel une facette spécifique de l'impulsivité interagit avec le genre ou le sexe pour modérer la probabilité de prendre le volant après avoir consommé du cannabis. Des participants de 17 à 35 ans possédant un permis de conduire valide ont été recrutés à partir de Facebook par le biais d’annonces payantes. Ils étaient invités à remplir un questionnaire portant sur leur caractéristique socio-démographique, leur habitude de consommation de cannabis, ainsi que sur les composantes de l'impulsivité. Une analyse de modération a été effectuée pour clarifier la relation entre la recherche de sensations, le genre et la conduite d’automobile à l'aide du SPSS PROCESS. Le modèle proposé inclut la recherche de sensations comme variable exogène directement associée à la conduite après la consommation du cannabis, et cette relation est modérée par le genre ressenti. Effectivement, le genre ressenti des participants semble être une variable modératrice de l’association entre la recherche de sensation et la prise de volant après avoir consommé du cannabis. Les implications de ces résultats seront discutées.

Novel sensations : modernist fiction and the problem of qualia

Day, Jonathan January 2014 (has links)
This thesis examines representations of sensation within modernist novels alongside contemporary philosophical debates over the concept of qualia. Concentrating on the work of Virginia Woolf, James Joyce, Percy Wyndham Lewis, and Samuel Beckett, it confronts a longstanding critical tradition that has tended to obscure or misunderstand the implications of arguments made by philosophers of mind in relation to literary descriptions of sensation. That the mind is a thing, and that modernist narrative fiction is particularly successful at representing that thing, has become a critical commonplace. In this thesis I argue that interpretations of modernism’s supposed ‘inward turn’ are founded on a mistaken notion of ‘cognitive realism’, a critical position endorsing the idea that it is both possible and desirable to describe the mind (conceived of as a stable and unchanging object) without loss through the development and judicial deployment of new literary techniques. The myth of the inward turn in its various incarnations – the psychologised modernism described by many literary critics in the 50s and 60s, and the neuromodernism subscribed to by many contemporary critics – is, I argue, largely the result of a set of inter-linked misconceptions which attend the cognitive realist paradigm. The notion of qualia is central to my thesis. Defined as the ineffable, irreducible, and subjective properties of conscious experience, qualia emerge concomitantly with modernism, developing out of G. E. Moore’s definition of ‘sense-data’ and Bertrand Russell’s category of ‘sensibilia’. Though still disputed within contemporary philosophy, qualia create huge problems for materialist theories of consciousness, threatening to undermine critical approaches to literature which contend that formal literary strategies can ever hope to transcend the limitations of symbolic language in conveying sensation. The ‘problem’ of qualia referred to in this thesis, therefore, is the problem the concept poses for symbolic descriptions (either mathematic, psychological, or literary) of mental states, especially when those descriptions make special claims (or are interpreted as making special claims) of mimetic veracity. The problem emerged within philosophy at precisely the point at which the representative claims of literature came under direct attack. This thesis argues, therefore, that it is a profoundly literary problem, and that the absence of ‘sensation’ from the written is simply a manifestation of the inherent limitations of language. A critical tendency to re-insert sensory experience into the process of reading – through phenomenological interpretations of modernism, or in contemporary ‘neuroaesthetic’ approaches to literature – thus point to a general anxiety that manifests itself most forcefully in relation to modernist fiction’s ability to ‘write’ sensation. This thesis employs the concept of qualia as a way of contextualising narratives of the mind – philosophical, literary and scientific – from the period. In doing so it seeks to historicise modernism’s ‘crisis of the senses’; locating this argument in a broader theoretical space and questioning the relevance (and novelty) of contemporary approaches to reading the senses in modernism.

Cardiac cycle related modulation of electrocutaneous pain and tactile stimuli

Wilkinson, Mary January 2014 (has links)
Research suggests hypertension is associated with reduced somatosensory perception. Further, natural fluctuations in blood pressure (BP) across the cardiac cycle have been shown to modulate nociceptive responding, pain and tactile sensitivity, suggesting that arterial baroreceptors may be important moderators of somatosensation. This thesis further examined the influence of natural fluctuations in BP, and thus baroreceptor activity, across the cardiac cycle on electrocutaneous pain and tactile sensory thresholds and pain-related evoked potentials (PREPs) in normotensive individuals. Study 1 found pain thresholds were higher, i.e. pain was reduced, during systole compared to diastole. Further analysis revealed only participants with low-normal systolic BP displayed this cardiac cycle modulation, suggesting tonic BP may moderate cardiac cycle-related pain modulation. In the second study, tactile sensory thresholds did not vary across the cardiac cycle. However, when participants were split into high-normal and low-normal BP groups, interactions between BP and tactile sensory thresholds across the cardiac cycle were revealed. This finding suggests tonic BP may be an important factor determining the cardiac cycle modulation of tactile sensation. Study 3 found no variation in the N2 or P2 peak amplitudes, or N2-P2 peak-to-peak amplitudes across the cardiac cycle at scalp recording sites Cz, C3, or C4. Furthermore, BP median split analyses revealed no BP Group or interaction effect. As previous work reported a systolic dampening of PREPs, these data suggest the cardiac cycle-related modulation of PREPs may not be as robust as other measures of pain such as the nociceptive flexion reflex. Study 4 reported, in line with Study 3, no cardiac cycle related modulation of PREPs following stimulation of the right and left hands. However, a Hand x Scalp Electrode Site x Interval interaction was revealed for N2 peak amplitudes. These data suggest that the combination of side of stimulation and scalp recording site may be important in determining the patterning of PREPs across the cardiac cycle. Taken together, the findings of these studies suggest that pain perception, and to a lesser extent tactile sensation, are influenced by natural variations in BP across the cardiac cycle. However, modulation appears dependent on tonic BP. Conversely, pain-related brain activity across the cardiac cycle was not affected by tonic BP, but may be influenced by the combination of stimulation and recording sites.

Why wet feels wet? : an investigation into the neurophysiology of human skin wetness perception

Filingeri, Davide January 2014 (has links)
The ability to sense humidity and wetness is an important sensory attribute for many species across the animal kingdom, including humans. Although this sensory ability plays an important role in many human physiological and behavioural functions, as humans largest sensory organ i.e. the skin seems not to be provided with specific receptors for the sensation of wetness (i.e. hygroreceptors), the neurophysiological mechanisms underlying this complex sensory experience are still poorly understood. The aim of this Thesis was to investigate the neurophysiological mechanisms underpinning humans remarkable ability to sense skin wetness despite the lack of specific skin hygroreceptors. It was hypothesised that humans could learn to perceive the wetness experienced when the skin is in contact with a wet surface or when sweat is produced through a complex multisensory integration of thermal (i.e. heat transfer) and tactile (i.e. mechanical pressure and friction) inputs generated by the interaction between skin, moisture and (if donned) clothing. Hence, as both thermal and tactile skin afferents could contribute significantly to drive the perception of skin wetness, their role in the peripheral and central sensory integration of skin wetness perception was investigated, both under conditions of skin s contact with an external (dry or wet) stimulus as well as during the active production of sweat. A series of experimental studies were performed, aiming to isolate the contribution of each sensory cue (i.e. thermal and tactile) to the perception of skin wetness during rest and exercise, as well as under different environmental conditions. It was found that it is not the contact of the skin with moisture per se, but rather the integration of particular sensory inputs which drives the perception of skin wetness during both the contact with an external (dry or wet) surface, as well as during the active production of sweat. The role of thermal (cold) afferents appears to be of a primary importance in driving the perception of skin wetness during the contact with an external stimulus. However, when thermal cues (e.g. evaporative cooling) are limited, individuals seem to rely more on tactile cues (i.e. stickiness and skin friction) to characterise their perception of skin wetness. The central integration of conscious coldness and mechanosensation, as sub-served by peripheral cutaneous A-nerve fibers, seems therefore the primary neural process underpinning humans ability to sense wetness. Interestingly, these mechanisms (i.e. integration of thermal and tactile sensory cues) appear to be remarkably consistent regardless of the modality for which skin wetness is experienced, i.e. whether due to passive contact with a wet stimulus or due to active production of sweat. The novelty of the findings included in this Thesis is that, for the first time, mechanistic evidence has been provided for the neurophysiological processes which underpin humans ability to sense wetness on their skin. Based on these findings, the first neurophysiological sensory model for human skin wetness perception has been developed. This model helps explain humans remarkable ability to sense warm, neutral and cold skin wetness.

Body mapping of perceptual responses to sweat and warm stimuli and their relation to physiological parameters

Gerrett, Nicola January 2012 (has links)
Regional differences in sweat gland output, skin temperature and thermoreceptor distribution can account for variations in regional perceptions of temperature, thermal comfort and wetness sensation. Large cohorts of studies have assessed these perceptual responses during sedentary activity but the findings are typically applied to a multitude of conditions, including exercise. Increases in sweat gland output, redistribution of blood flow and changes in skin and core temperature are basic responses to exercise in most conditions and these ultimately influence our perceptual responses. The primary aim of this thesis is to determine factors that influence regional differences in thermal sensation, thermal comfort and wetness sensation during exercise in moderate to hot conditions. The secondary aim is to develop and understand an additional variable, galvanic skin conductance (GSC) that can be used to predict thermal comfort and wetness sensation. The aim of the first study (Chapter 4) was to determine the influence of exercise on thermal sensitivity and magnitude sensation of warmth to a hot-dry stimulus (thermal probe at 40°C) and assess if any gender-linked differences and/or regional differences exist. From the data, body maps indicating sensitivity were produced for both genders during rest and exercise. Females had more regional differences than males. Overall sensitivity was greatest at the head, then the torso and declined towards the extremities. The data showed that exercise did not cause a significant reduction in thermal sensitivity but magnitude estimation was significantly lower after exercise for males and selected locations in females. The cause of a reduced magnitude sensation is thought to be associated with exercise induced analgesia; a reduction in sensitivity due to exercise related increases in circulating hormones. As the literature suggests that thermal comfort in the heat is influenced by the presence of sweat, the next study and all proceeding studies were concerned with this concept. In Chapter 5, building on earlier studies performed in our laboratories, the influence of local skin wettedness (wlocal) on local thermal comfort and wetness sensation was investigated in a neutral dry condition (20.2 ± 0.5°C and 43.5 ± 4.5% RH) whilst walking (4.5 km∙hr-1). Regional differences in wlocal were manipulated using specialised clothing comprising permeable and impermeable material areas. Strong correlations existed between local thermal comfort and local wetness sensation with the various measured wlocal (r2>0.88, p<0.05 and r2>0.83, p<0.05, respectively). The thermal comfort limit was defined as the wlocal value at which the participants no longer felt comfortable. Regional comfort limits for wlocal were identified (in order of high-low sensitivity); lower back (0.40), upper legs (0.44), lower legs (0.45), abdomen (0.45), chest (0.55), upper back (0.56), upper arms (0.57) and lower arms (0.65). The maximum degree of discomfort and wetness sensation experienced during the investigation was kept deliberately low in an attempt to determine the threshold values. Therefore comfort scores and wetness scores rarely reached a state of uncomfortable or wet so the next step was to assess these relationships when sweat production is high and the sensations worsened. However, pilot testing indicated that a ceiling effect would occur for wlocal at high levels of sweat production whilst thermal discomfort increased indicating wlocal was not the determining parameter in that case. Thus an additional parameter was required. The chosen parameter was galvanic skin conductance (GSC) due to its alleged ability to monitor pre-secretory sweat gland activity, skin hydration and surface sweat. In Chapter 6, the reliability, reproducibility and validity of GSC were confirmed in a series of pilot tests. Moderate to strong correlations were found between GSC and regional sweat rate (RSR) (r2>0.60, p<0.05) and wlocal (r2>0.55, p<0.05). The literature suggests standardising GSC relative to a minimum and maximum GSC value; however uncertainties arise when attempting to achieve maximum GSC. Therefore a change from baseline (∆GSC) was chosen as the proposed method of standardisation for further use. Additional results (from Chapter 9) revealed that ∆GSC also reflects pre-secretory sweat gland activity as it increased prior to sweat being present on the skin surface and prior to an increase in RSR. In Chapter 9, also hydration of the stratum corneum was measured using a moisture meter and the results revealed that it has an upper limit; indicating maximal hydration. From this point of full skin saturation ∆GSC and RSR markedly increase though sensations did not. It was also found that ∆GSC is only influenced by surface sweat that is in direct contact with the electrode and is not influenced by sweat elsewhere on the skin surface between electrodes. Higher levels of thermal discomfort have rarely been explored and neither has its relationship with wlocal. The ability of ∆GSC and wlocal to predict local thermal comfort and wetness sensation were compared in two different conditions to elicit low and high sweat production. Unlike Chapter 5, the body sites were not manipulated to control wlocal but allowed to vary naturally over time. The test was carried out on males (Chapter 7) and females (Chapter 8) to compare any gender linked differences and the results suggest that females are more sensitive than males to the initial presence of sweat. For both genders, wlocal and ∆GSC are strong predictors of thermal comfort and wetness sensation. More importantly, wlocal can only be used to predict local thermal comfort in conditions of low sweat production or low levels of thermal discomfort. However, once sweat production increases and thermal discomfort worsens ΔGSC (and not wlocal) can predict thermal comfort. Due to low sweat production observed in females indicates that this is only relevant for females. It appears that epidermal hydration has an important role on influencing thermal comfort. Receptors influencing our perceptual responses are located in the epidermis and when sweat is produced and released onto the skin surface, this epidermis swells and the sensitivity of receptors are said to increase. wlocal indicates the amount of moisture present on the skin surface, yet ∆GSC indicates presecretory sweat gland activity and epidermal hydration where the receptors are located. This may explain why on numerous occasions thermal comfort had a stronger relationship with ∆GSC than wlocal. Where Chapter 5 indicated the true local comfort limits for each respective zone, Chapter 7 and 8 provided a global picture of how local regions interact and influence local thermal comfort across the body. When wlocal varies naturally, the torso areas naturally produce more sweat than the extremities and it seemed that these areas produce so much more sweat than the extremities that they dominate local thermal comfort across the whole body. This is referred to in this thesis as a model of segmental interaction. As with thermal comfort, wetness sensation had strong relationships with wlocal and ∆GSC. The results also revealed a strong relationship between wetness sensation and thermal comfort. In contrast to the widely supported claim, a drop in skin temperature is not required to stimulate a wetness sensation. The point at which we detect sweat and when it becomes uncomfortable occurs at different wlocal values across the body. Thermal comfort is shown to be influenced by sweat during exercise in moderate-to-hot conditions. As w has an upper limit the findings suggest that it cannot predict thermal comfort during high sweat rates. Galvanic skin conductance monitors the process of sweat production more closely and thus is a better predictor of thermal comfort during all conditions and particularly during high sweat production. The strong relationship between thermal comfort and wetness sensation confirm the role of sweat production on thermal comfort. Gender differences to perceptual responses were observed, with females generally being more sensitive to sweat and a warm thermal stimulus than males. Regional differences to sweat and a warm stimulus generally suggest that the torso area is more sensitive than the extremities. This is important not only for sports clothing design but also protective clothing at the work place.

Children's expressions of pain and bodily sensation in family mealtimes

Jenkins, Laura January 2012 (has links)
This study applied conversation analysis for the first time to episodes in which children express pain and bodily sensations in the everyday setting of family mealtimes. It focuses on the components of children s expressions, the character of parents responses, and how the sequence is resolved. Three families who had a child with a long term health condition were recruited through voluntary support groups and agreed to film 15-17 mealtimes. In total 47 mealtimes were recorded totalling 23 hours of data. Each family had two children aged 15 months to nine years and included a heterosexual married couple. This data was supplemented by archives in the Discourse and Rhetoric Group: a further nine hours of mealtime recordings by two families each with two children aged three to seven years. The analysis describes four key components of children s expressions of bodily sensation and pain: lexical formulations; prosodic features; pain cries and embodied actions, revealing the way in which they can be built together to display different aspects of the experience. The results highlight the nature of these expressions as initiating actions designed in and for interaction. An examination of the sequence that follows demonstrates the negotiated character of pain. Descriptions of the nature of the child s pain and its authenticity are produced, amended, resisted or accepted in the turns that follow. During these sequences participant orientations reveal the pervasive relevance of eating related tasks that characterises mealtime interaction. The discussion concludes by describing the unique insights into the negotiated rather than private nature of a child s pain demonstrated by this study, and the way in which pain can be understood as produced and dealt with as part of the colourful tapestry of everyday family life in which everyday tasks are achieved, knowledge and authority is claimed and participants are positioned in terms of their relationship to one another.

Abortion, sentience and moral standing : a neurophilosophical appraisal

Van Bogaert, Louis-Jacques 12 1900 (has links)
Thesis (PhD)--University of Stellenbosch, 2002. / ENGLISH ABSTRACT: Moral theories on abortion are often regarded as mutually exclusive. On the one hand, pro-life advocates maintain that abortion is always morally wrong, for life is sacred from its very beginning. On the other hand, the extreme liberal view advocated by the absolute pro-ehoieers claims that the unborn is not a person and has no moral standing. On this view there is no conflict of rights; women have the right to dispose of their body as they wish. Therefore, killing a non-person is always permissible. In between the two extreme views, some moral philosophers argue that a 'pre-sentient' embryo or fetus cannot be harmed because it lacks the ability to feel pain or pleasure, for it is 'sentience' that endows a living entity (human and non-human) with moral considerability. Therefore, abortion of a pre-sentient embryo or fetus is permissible. Neurophilosophy rests a philosophical conclusion on neurological premises. In other words, to be tenable sentientism - the claim that sentience endows an entity with moral standing - needs robust neurobiological evidence. The question is, then: What is the basic neuroanatomical and neurophysiological apparatus required to be sentient? The answer to that question requires a fair understanding of the evolution, anatomy and function of the brain. The exploration thereof shows quite convincingly that the advocates of sentientism do not provide convincing arguments to root their theory in neurobiological facts. Their claims rest rather on emotions and on behaviours that look like a reaction to pain. The other shortcoming of sentientism is that it fails to distinguish pain from suffering, and that as a utilitarian moral theory it considers only the alleged pain of the aborted sentient fetus and disregards the pregnant woman's pain and suffering. And, finally, sentientism leaves out of our moral consideration living and non-living entities that deserve moral respect. The main thrust of the dissertation is that the argument of sentience as its advocates present it has no neurophilosophical grounds. Therefore, the argument from sentience is not a convincing argument in favour or against abortion. / AFRIKAANSE OPSOMMING: Morele teorieë wat handeloor aborsie word dikwels as wedersyds uitsluitend beskou. "Pro-life" kampvegters hou oor die algemeen vol dat aborsie onder alle omstandighede moreel veroordeelbaar is, omdat die lewe van meet af heilig is. Daarteenoor hou die ekstreem-liberale oogpunt, wat deur "Pro-choice" voorstaanders ingeneem word, vol dat die ongeborene nie 'n persson is nie, en as sulks geen morele status het nie. Volgens hierdie standpunt is daar geen konflik van regte hier ter sprake nie; vroue het uitsluitelike beskikkingsreg oor hulle eie liggame. Dus is dit toelaatbaar om onder hierdie omstandighede 'n "nie-persoon" om die lewe te bring. Tussen hierdie twee ekstreme standpunte argumenteer party morele filosowe dat die voorbewuste embrio of fetus nie skade berokken kan word nie, omdat dit nie oor die vermoë beskik om pyn of plesier te voel nie. Dit is juis bewussyn en die vermoë om waar te neem wat morele status aan 'n entiteit (hetsy menslik of nie-menslik) verleen. Dus is dit toelaatbaar om 'n voorbewustw embrio of fetus te aborteer. Neurofilosofie basseer filosofiese gevolgtrekkinge op neurolgiese beginsels. Met andere woorde, so 'n standpunt sal eis dat 'n argument oor bewustheid op betroubare neurologiese feite gebasseer word, om sodoende met sekerheid morele status, al dan nie, aan de fetus of embrio toe te ken. Die vraag is dan: Wat is die basiese neuroanatomiese en neurofiologiese apparatuur waaroor 'n entiteit moet beskik om as bewus beskou te word? Die antwoord op hierdie vraag vereis dan ook 'n redelik grondige kennis van die evolusie, anatomie en funksie van die brein. Wanneer die vraagstuk van naderby beskou word, word dit duidelik dat voorstaanders van die bewustheids-argument oor die algemeen nie hulle standpunte op oortuigende, neurologiese feite berus nie. Hulle beweringe rus dan eerder op emosie en op waargenome optredes wat voorkom asof dit 'n reaksie op pyn is. Nog 'n tekortkoming van die bewustheids-argument is dat dit nie 'n onderskeid tref tussen die konsep van pyn en die van leiding nie, en dat dit as 'n utilitaristiese morele teorie slegs die beweerde pyn van die ge-aborteerde fetus in ag neem en nie die leiding van die swanger vrouw nie. Ten slotte neem die bewustheids-argument ook nie morele status van lewende en nie-lewende entiete, wat geregtig is op morele respek, in ag nie. Die hoof uitgangspunt van hierdie dissertasie is dan dat die bewustheids-argument, soos wat dit tans deur voorstanders daarvan voorgehou word, nie neurofilosfies begrond kan word nie. Dus is die argument vanuit 'n bewustheids-standpunt nie 'n oortuigende argument hetsy vir of teen aborsie nie.

Interior sensation and exterior forces : cutting away

Salazar, Samantha Parker 09 October 2014 (has links)
In my work, traditional printmaking techniques are pushed to their limits as a foundation for cut-paper installations and sculptures. The work reflects on notions of interiority and exteriority in relation to the body and nature, drawing from my experiences in meditation to create a two and three-dimensional visual play primarily using paper. Because of their illustrative looseness, the biomorphic structures convey a variety of sensations, shapes, and movements that are related to the interior of the body and exterior forces in nature. In this report, I plan to discuss topics of process, materiality, sensation, objecthood and phenomenology within the context of my work and as these topics relate to other artists such as: Lee Bontecou, Francis Bacon, Oskar Fischinger, Richard Serra, and Judy Pfaff. I also plan to indicate a contemporary and art historical context for the work, placing my pieces within a specific canon of visual culture. / text
