Backtracks: a devised performance

Backtracks aimed to investigate critical relationships between audio-visual technologies and live performance, emphasising technologies producing sound, contrasted with non-amplified bodily sound. Drawing on methodologies for studying avant garde theatre, live performance and the performing body, it was informed by work in critical and cultural theory by, for example, Steven Connor and Jonathan Rée, on the body's experience and interpretation of sound. The performance explored how shifting national boundaries, mobile workforces, complex family relationships, cultural pluralities and possibilities for bodily transformation have compelled a re-evaluation of what it means to feel 'at home' in modernity. Using montages of live and mediated images, disrupted narratives and sound, it evoked destablised identities which characterise contemporary lived experience, and enacted the displacement of certainties provided by family and nation, community and locality, body and selfhood. Homer's Odyssey framed the performance: elements could be traced in the mise-en-scène; in the physical presence of Athene, the narrator and Penelope weaving mementoes from the past into her loom; and in voice-overs from Homer's work. The performance drew on personal experiences and improvisations, structured around notions of journey. It presented incomplete narratives, memories, repressed anxieties and dreams through different combinations of sounds, music, mediated images, movement, voice and bodily sound. The theme of travel was intensified by performers carrying suitcases and umbrellas, by soundtracks incorporating travel effects, and by the distorted video images of forms of transport playing across 'screens' which proliferated across the space (sails, umbrellas, the loom, actors' bodies). The performance experimented with giving sound and silence performative dimensions, including presenting sound in visual and imagistic ways, for example by using signs from deaf sign language. Through-composed soundtracks of live and recorded song, music, voice-over, and noise exploited the viscerality of sound and disrupted cognitive interpretation by phenomenological, somatic experience, thereby displacing the impulse for closure/destination/home.

Attacking human implants: a new generation of cybercrime

Human ICT implants, such as RFID implants, cochlear implants, cardiac pacemakers, Deep Brain Stimulation, bionic limbs connected to the nervous system, and networked cognitive prostheses, are becoming increasingly complex. With ever-growing data processing functionalities in these implants, privacy and security become vital concerns. Electronic attacks on human ICT implants can cause significant harm, both to implant subjects and to their environment. This paper explores the vulnerabilities which human implants pose to crime victimisation in light of recent technological developments, and analyses how the law can deal with emerging challenges of what may well become the next generation of cybercrime: attacks targeted at technology implanted in the human body. After a state-of-the-art description of relevant types of human implants and a discussion how these implants challenge existing perceptions of the human body, we describe how various modes of attacks, such as sniffing, hacking, data interference, and denial of service, can be committed against implants. Subsequently, we analyse how these attacks can be assessed under current substantive and procedural criminal law, drawing on examples from UK and Dutch law. The possibilities and limitations of cybercrime provisions (eg, unlawful access, system interference) and bodily integrity provisions (eg, battery, assault, causing bodily harm) to deal with human-implant attacks are analysed. Based on this assessment, the paper concludes that attacks on human implants are not only a new generation in the evolution of cybercrime, but also raise fundamental questions on how criminal law conceives of attacks. Traditional distinctions between physical and non-physical modes of attack, between human bodies and things, between exterior and interior of the body need to be re-interpreted in light of developments in human implants. As the human body and technology become increasingly intertwined, cybercrime legislation and body-integrity crime legislation will also become intertwined, posing a new puzzle that legislators and practitioners will sooner or later have to solve.

An enhanced fall detection system for elderly person monitoring using consumer home networks

Various fall-detection solutions have been previously proposed to create a reliable surveillance system for elderly people with high requirements on accuracy, sensitivity and specificity. In this paper, an enhanced fall detection system is proposed for elderly person monitoring that is based on smart sensors worn on the body and operating through consumer home networks. With treble thresholds, accidental falls can be detected in the home healthcare environment. By utilizing information gathered from an accelerometer, cardiotachometer and smart sensors, the impacts of falls can be logged and distinguished from normal daily activities. The proposed system has been deployed in a prototype system as detailed in this paper. From a test group of 30 healthy participants, it was found that the proposed fall detection system can achieve a high detection accuracy of 97.5%, while the sensitivity and specificity are 96.8% and 98.1% respectively. Therefore, this system can reliably be developed and deployed into a consumer product for use as an elderly person monitoring device with high accuracy and a low false positive rate.

Comparison of low-power wireless communication technologies for wearable health-monitoring applications

Health monitoring technologies such as Body Area Network (BAN) systems has gathered a lot of attention during the past few years. Largely encouraged by the rapid increase in the cost of healthcare services and driven by the latest technological advances in Micro-Electro-Mechanical Systems (MEMS) and wireless communications. BAN technology comprises of a network of body worn or implanted sensors that continuously capture and measure the vital parameters such as heart rate, blood pressure, glucose levels and movement. The collected data must be transferred to a local base station in order to be further processed. Thus, wireless connectivity plays a vital role in such systems. However, wireless connectivity comes at a cost of increased power usage, mainly due to the high energy consumption during data transmission. Unfortunately, battery-operated devices are unable to operate for ultra-long duration of time and are expected to be recharged or replaced once they run out of energy. This is not a simple task especially in the case of implanted devices such as pacemakers. Therefore, prolonging the network lifetime in BAN systems is one of the greatest challenges. In order to achieve this goal, BAN systems take advantage of low-power in-body and on-body/off-body wireless communication technologies. This paper compares some of the existing and emerging low-power communication protocols that can potentially be employed to support the rapid development and deployment of BAN systems.

Using ninhydrin to detect gravesoil

Some death scene investigations commence without knowledge of the location of the body and/or decomposition site. In these cases, it is necessary to locate the remains or the site where the body decomposed prior to movement. We hypothesized that the burial of a mammalian cadaver will result in the release of ninhydrin reactive nitrogen (NRN) into associated soil and that this reaction might have potential as a tool for the identification of clandestine graves. Juvenile rat (Rattus rattus) cadavers were buried in three contrasting soil types in Australian tropical savanna ecosystems and allowed to decompose over a period of 28 days. Soils were sequentially harvested and analyzed for NRN. Cadaver burial resulted in an approximate doubling (mean = 1.7 ± 0.1) in the concentration of soil NRN. This reaction has great potential to be used as a presumptive test for gravesoil and this use might be greatly enhanced following more detailed research.

Amor intellectualis diaboli

An essay on love and liberty in the writings of Gillian Rose, Marquis de Sade, Max Horkheimer and Theodor W. Adorno, written in response to the following provocation: "Encore un effort. A banderole publicitaire carries the breathless descriptions of the new fashions for 1968, when anything goes and details place the accent on this or that part of the body and its adornment: a pair of shoes that come off in a struggle, for example, the heel of one snapped off; a striking checked shirt, with two buttons undone; a light-coloured trench coat (perfect for a May day); a blouson-style jacket that allows easy freedom of movement; place casual slacks worn with an ankle boot. Beauty is in the streets as fashion becomes democratic (or so say the houses of haute couture), while the philosopher of the boudoir extorts us once again to make an effort if we wish to be republicans. Here, to an assembled crowd of sensitive men and women, which petit-maitre or dangerous man of principles would suggest that the only moral system to reinforce political revolution is that of libertinage, the revenge of nature's course against the aberrations of society?"

The Immune-Pineal Axis Stress as a Modulator of Pineal Gland Function

The temporal organization of mammals presents a daily adjustment to the environmental light/dark cycle. The environmental light detected by the retina adjusts the central clock in the suprachiasmatic nuclei, which innervate the pineal gland through a polysynaptic pathway. During the night, this gland produces and releases the nocturnal hormone melatonin, which circulates throughout the whole body and adjusts several bodily functions according to the existence and duration of darkness. We have previously shown that during the time frame of an inflammatory response, pro-inflammatory cytokines, such as tumor necrosis factor-a, inhibit while anti-inflammatory mediators, such as glucocorticoids, enhance the synthesis of melatonin, interfering in the daily adjustment of the light/dark cycle. Therefore, injury disconnects the organism from environmental cycling, while recovery restores the light/dark information to the whole organism. Here, we extend these observations by evaluating the effect of a mild restraint stress, which did not induce macroscopic gastric lesions. After 2 h of restraint, there was an increase in circulating corticosterone, indicating activation of the hypothalamus-pituitary-adrenal (HPA) axis. In parallel, an increase in melatonin production was observed. Taking into account the data obtained with models of inflammation and stress, we reinforce the hypothesis that the activity of the pineal gland is modulated by the state of the immune system and the HPA axis, implicating the darkness hormone melatonin as a modulator of defense responses.

New Species of Earless Lizard Genus Heterodactylus (Squamata: Gymnophthalmidae) from the Highlands of Chapada Diamantina, State of Bahia, Brazil

A new species of Heterodactylus is described based on two specimens obtained in the highlands of Chapada Diamantina, state of Bahia, Brazil. The new lizard is characterized by very elongate body and tail, absence of external ear opening, presence of moveable eyelids, absence of prefrontals and frontoparietals, a vestigial interparietal, 37-39 dorsal and 27-29 ventral transverse scale rows, 23-25 scales around midbody, six gular scale rows, and 10-11 and 14-15 fourth finger and fourth toe infradigital lamellae, respectively. The new species is most similar to Heterodactylus lundii from which it differs by the absence of contact between frontal and interparietal, by having wider than long parietals, smooth posterior dorsal scales, posterior ventral scales almost twice longer than wide, a lower number of scales around midbody, last supralabial in contact with the granules of the ear depression, and a more elongate body. The new species occurs about 1,100 km north of the northernmost known record of H. lundii. Species of Heterodactylus seem to be restricted to areas of cold climates associated with high latitudes and mountainous areas of eastern Brasil.

Acute toxicity of a single gavage dose of fumonisin B(1) in rabbits

The aim of this study was to determine the clinical, pathological and mycotoxicological effects of oral administration of fumonisin B, (FBI) in rabbits. Eighteen rabbits were randomly assigned to two experimental groups: control group, 0 mg FB(1): fumonisin group. 31.5 mg FB(1)/kg body weight, corresponding to about 630 mg FB(1)/kg diet. Fumonisin administered as a single oral dose to rabbits resulted in acute toxicity, significantly interfering with body and liver weight. Serum biochemical analysis revealed a significant increase of total protein, alkaline phosphatase (AP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyltransferase (GGT), urea and creatinine in the group receiving FBI compared to control animals, a finding characterizing hepatic and renal injury in this group. Urinary protein concentrations were markedly elevated at 12,24,48 and 72 h after dosing, although visible pathological abnormalities were not observed, probably because of rapid repair of the damage. FBI was detected in feces, with a maximum concentration at 24h after administration, indicating that the enterohepatic circulation is important in rabbits. FBI concentrations found in urine were low, with peak elimination at 12 h after intoxication. The highest FBI concentrations were observed in feces compared to urine and liver, demonstrating that feces are the main routes of excretion. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

Abnormal Corpus Callosum Integrity in Bipolar Disorder: A Diffusion Tensor Imaging Study

Objective: Abnormalities in the anterior interhemispheric connections provided by the corpus callosum (CC) have long been implicated in bipolar disorder (BID). In this study, we used complementary diffusion tensor imaging methods to study the structural integrity of the CC and localization of potential abnormalities in BD. Methods: Subjects included 33 participants with BID and 40 healthy comparison participants. Fractional anisotropy (FA) measures were compared between groups with region of interest (ROD methods to investigate the anterior, middle, and posterior CC and voxel-based methods to further localize abnormalities. Results: In ROI-based analyses, FA was significantly decreased in the anterior and middle CC in the BID group (p <.05). Voxel-based analyses similarly localized group differences to the genu, rostral body, and anterior midbody of CC (p <.05, corrected). Conclusion: The findings demonstrate abnormalities in the structural integrity of the anterior CC in BID that might contribute to altered interhemispheric connectivity in this disorder.

"Porque quiero casarme con un varón hermoso de la orilla del mar" Un análisis de lo grotesco femenino de María Josefa en La casa de Bernarda Alba

This essay is an analysis of the character María Josefa in the play 'The House of Bernarda Alba' (1936) by Federico García Lorca. It is hypothesized that the character of María Josefa can be considered a distorting mirror of the femininity presented in the play, and that through María Josefa this femininity is both revealed and problematized. The analysis adopts theories from the field of the (female) grotesque, using terminology both from Mikhail Bakhtin and Mary Russo. Throughout the analysis it is demonstrated how the character of María Josefa challenges the boundaries and norms which are dictated by Bernarda to control the women of the house. These conventions are challenged by María Josefa with the use of her loud speech, her dressed up appearance, and in her physical resistance. In this manner María Josefa is creating and embodying an alternate feminine view that is uncovered through her consistent provocation and by making herself into "a spectacle", a transboundary behaviour that is well interpreted within the theories of carnival, the grotesque body, and the spectacle of the female grotesque.

Konsekvenser av rollövertagandet : ”I”, ”me” och individualiteten

Consequences of role taking: the ”I”, the ”me” and individuality This paper analyzes the tendency of taking the ”I” and the ”me” in G. H. Meads theory of role taking as two separate, qualitatively different parts of human personality, the ”I” being of individual origin, the ”me” of social. In the original Meadian sense role taking gives rise to both the ”I” and the ”me”. They are dialectically united rather than dualistically separated aspects. They refer to the joint functional power of the subject, finding itself as an object, mediated by the Other. As a consequence, the link between body and the social world becomes theoretically more stringent, as the body is given its place as a cognitive social object among others, this by contrast to interpretations where the body is left as an object mainly outside the human social experience and as a source of agency sui generis, a conception which is in opposition to Meads. The stress on the ”I”-phase, as related to body and concrete action in combination with its direct relation to the ”me”-phase, actualizes Mead as a forerunner in modern biologic/neurologic research on human perceptual, motivational and intentional capacity.Swedish Mead interpreters are critically analyzed. Interpretations of Charon, Giddens, Joas and Habermas are partly scrutinized. The author defines the conceptual pair in terms of activity, subjectivity, temporal relativity and distance.

Överviktens betydelser

Meanings of overweight In societal discourses overweight is defined as a growing individual and a social problem leading to sickness and disability, mental distress, increased use of health care and reduced economic productivity. A strong normative pressure is directed at the overweight but relatively few succeed in reducing their weight. Therefore, the overweight need to manage a double stigma; the overweight body per se and their inability to conform to norms about bodyweight. This article investigates how individuals present their overweight to their social environment. Empirical data was collected as part of an evaluation study of a keep-fit project directed at home-care staff. Qualitative interviews were conducted with 49 participants and 30 of them had either tried or were trying to reduce their weight. The analysis shows that the informants presented a divided self consisting of a biological body, with its own drives, and a mind that is aware of the body and its social meanings. They portrayed their lives as a battle between these two sides. Their presentations of the divided self can be analysed as a defence of their social selves. The overweight can account for the kilos by blaming the biological drives, which leaves the core of themselves – their minds – unblemished. They can express an intention to loose weight and thereby conform to norms about bodyweight. When they fail to loose weight, the responsibility can be attributed to the unruly body.

Physiological demands of competitive elite cross-country skiing

Introduction Researchers have, for decades, contributed to an increased collective understanding of the physiological demands in cross-country skiing; however, almost all of these studies have used either non-elite subjects and/or performances that emulate cross-country skiing. To establish the physiological demands of cross-country skiing, it is important to relate the investigated physiological variables to the competitive performance of elite skiers. The overall aim of this doctoral thesis was, therefore, to investigate the external validity of physiological test variables to determine the physiological demands in competitive elite cross-country skiing. Methods The subjects in Study I – IV were elite male (I – III) and female (III – IV) cross-country skiers. In all studies, the relationship between test variables (general and ski-specific) and competitive performances (i.e. the results from competitions or the overall ski-ranking points of the International Ski Federation (FIS) for sprint (FISsprint) and distance (FISdist) races) were analysed. Test variables reflecting the subject’s general strength, upper-body and whole-body oxygen uptake, oxygen uptake and work intensity at the lactate threshold, mean upper-body power, lean mass, and maximal double-poling speed were investigated. Results The ability to maintain a high work rate without accumulating lactate is an indicator of distance performance, independent of sex (I, IV). Independent of sex, high oxygen uptake in whole-body and upper-body exercise was important for both sprint (II, IV) and distance (I, IV) performance. The maximal double-poling speed and 60-s double-poling mean power output were indicators of sprint (IV) and distance performance (I), respectively. Lean mass was correlated with distance performance for women (III), whereas correlations were found between lean mass and sprint performance among both male and female skiers (III). Moreover, no correlations between distance performance and test variables were derived from tests of knee-extension peak torque, vertical jumps, or double poling on a ski-ergometer with 20-s and 360-s durations (I), whereas gross efficiency while treadmill roller skiing showed no correlation with either distance or sprint performance in cross-country skiing (IV). Conclusion The results in this thesis show that, depending on discipline and sex, maximal and peak oxygen uptake, work intensity at the lactate threshold, lean mass, double-poling mean power output, and double-poling maximal speed are all externally valid physiological test variables for evaluation of performance capability among elite cross-country skiers; however, to optimally indicate performance capability different test-variable expressions should be used; in general, the absolute expression appears to be a better indicator of competitive sprint performance whereas the influence of body mass should be considered when evaluating competitive distance performance capability of elite cross-country skiers.

Embodying a mine site : enacting cyborg curriculum

This paper focuses on the construction of my post-operatively scarred body as a mine site, my experiences with reconstructively normalizing its appearance as a cyborg, and the implications for my work as an environmental educator  interested in how the body of a theorist is presented within theoretical spaces. The paper is not a victim's story as such, but rather a response to the  hypothesis that illness is a call for stories, that the body needs a voice that disease and illness take away. It relates Donna Haraway's notions of the cyborg and other feminist poststructuralist work to both my living body and the body of my curriculum work in environmental education.
