OBJECTIVES: For violinists, it is common practice to play while standing or sitting. When playing in an orchestra, generally two persons share one music stand, with one sitting to the right and the other to the left of the stand. The present study investigated specific movement patterns while playing in these different positions. METHODS: Using a posturographic device and 3D motion capture, the body weight distributions and specific body movements of 19 violinists were analyzed. RESULTS: Results showed unbalanced weight distributions while sitting in front of or oriented to the right of the music stand compared to the almost even distributions while standing or oriented to the left of the stand. Analyses of movement patterns showed significant differences between standing and sitting, mainly in the upper body parts with less movability while sitting. While sitting in front of or oriented to the right of the music stand, the right bowing arm showed more restricted movements compared to other positions. CONCLUSION: The playing positions are discussed with regard to possible physiological stress and health risks. The study emphasizes the importance of different playing positions and offers starting points for discussion of postural influences and sensible handling of the instrument in performance and practice for violinists.

The Right

No one wants to be treated like an object, regarded as an item of property, or put up for sale. Yet many people frame personal autonomy in terms of self-ownership, representing themselves as property owners with the right to do as they wish with their bodies. Others do not use the language of property, but are similarly insistent on the rights of free individuals to decide for themselves whether to engage in commercial transactions for sex, reproduction, or organ sales. Drawing on analyses of rape, surrogacy, and markets in human organs, this book challenges notions of freedom based on ownership of our bodies and argues against the normalization of markets in bodily services and parts. The book explores the risks associated with metaphors of property and the reasons why the commodification of the body remains problematic. The book asks what is wrong with thinking of oneself as the owner of one's body? What is wrong with making our bodies available for rent or sale? What, if anything, is the difference between markets in sex, reproduction, or human body parts, and the other markets we commonly applaud? The book contends that body markets occupy the outer edges of a continuum that is, in some way, a feature of all labor markets. But it also emphasizes that we all have bodies, and considers the implications of this otherwise banal fact for equality. Bodies remind us of shared vulnerability, alerting us to the common experience of living as embodied beings in the same world. Examining the complex issue of body exceptionalism, the book demonstrates that treating the body as property makes human equality harder to comprehend.

The body of a hermit crab shows asymmetrical morphology, which may be related to utilization of the dextral shell. To examine the effect of the shell, we reared Pagurus filholi (De Man, 1887) from the glaucothoe stage to full-sized adults, in a sinistral shell, in a straight tusk shell, without a shell, and in a normal dextral shell as a control. Body parts that show the most conspicuous asymmetry, uropods, pleopods and chelipeds, were checked at the time of the shedding of exuviae during rearing. No inversion of laterality on these characters was observed. However, in crabs subjected to conditions other than a dextral shell, the otherwise rather short right uropod became somewhat extended, and in those reared in sinistral shells, the right major cheliped was more enlarged.

The study was designed to determine the size of some body parts of the Super Kampong chicken and its relationship with body weight. The study was conducted at the Teaching Farm of Animal Science Faculty, University of Mataram, in Lingsar Village, West Lombok. The study used 60 male and 96 female Super Kampong chickens which were maintained intensively. The variables observed were body weight, head circumference, neck length, wing length, back length, chest circumference, chest width, upper and lower thigh length, metatarsus length, metatarsus circumference, and third finger length. Measurements were made for each individual bird at 13 weeks of age using yarn then measured with a tape measure, while the dimension of chest width was assigned  by measuring the distance between the right and right sides of the chest using calipers. The results found that the body parts that had the biggest contribution to the body weight of the Super Kampong chickens at 13 weeks old were the size of the lower thigh length in the male chicken and the size of the chest circumference in the female chicken.

Noninformative Vision

Vision of the body without task cues enhances tactile discrimination performance. This effect has been investigated only with static visual information, although our body usually moves, and dynamic visual and bodily information provides ownership (SoO) and agency (SoA) sensations to body parts. We investigated whether vision of body movements could enhance tactile discrimination performance. Participants observed white dots without any textural information showing lateral hand movements (dynamic condition) or static hands (static condition). For participants experiencing the dynamic condition first, it induced a lower tactile discrimination threshold, as well as a stronger SoO and SoA, compared to the static condition. For participants observing the static condition first, the magnitudes of the enhancement effect in the dynamic condition were positively correlated between the tactile discrimination and SoO/SoA. The enhancement of the dynamic visual information was not observed when the hand shape was not maintained in the scrambled white dot images. Our results suggest that dynamic visual information without task cues can enhance tactile discrimination performance by feeling SoO and SoA only when it maintains bodily information.

Dance Movements

This study investigated effects of mirror and metronome use on spontaneous upper body movements by 10 preprofessional dancers in a motor task in which maximally diverse upper body movement patterns were targeted. Hand and trunk accelerations were digitally recorded utilizing accelerometers and analyzed using polar frequency distributions of the realized acceleration directions and sample entropy of the acceleration time. Acceleration directions were more variably used by the arms than by the torso, particularly so when participants monitored their performance via a mirror. Metronome use hardly affected the predictability of the acceleration time series. The findings underscore the intrinsic limitations that people experience when being asked to move randomly and reveal moderate effects of visual and acoustic constraints on doing so in dance.

BackgroundDelusions relating to the body, a ready source of information about the immediate experiences of psychotic patients, have not been systematically studied. We attempted an account of the phenomena, looking for differences between diagnostic groupings in the type and lateralisation of such phenomena, and for evidence of localisation.MethodSomatic delusions elicited at interview with 550 Research Diagnostic Criteria-diagnosed psychotic patients were categorised according to content, and the results were compared across diagnostic groupings.ResultsSignificant differences were demonstrated, both at the level of individual delusions and in the nature and overall pattern of such delusions. There were also differences between diagnostic groups in the choice of body parts involved. Among male patients there were significant differences in laterality between the groups, with schizophrenic subjects locating abnormal phenomena principally on the left and depressive subjects on the right. A provisional taxonomy of bodily delusions was developed.ConclusionPhenomenological differences between the psychoses were demonstrated and the results offer some support for current hypotheses of localisation of brain dysfunction in the psychotic illnesses.

Purpose The purpose of this paper is to determine the effects of clothing ease and body postures on the size and distribution of the air gap as well as the body coverage with the clothing. Design/methodology/approach Visual and quantitative analyses were conducted using a 3D body scanner and Geomagic Software. The air gap size and clothing area factor (fcl) in three test coverall and seven selected postures were calculated and compared. Findings The results indicated that both the clothing ease and body postures had a strong effect on the air gap and clothing coverage, especially the more complex the postures, the wider the range of influence. Nevertheless, these effects varied over body regions, being stronger at the lower body than the upper body. The air gap size at the left side of the body was generally larger than the right side. It was also found that the clothing coverage was linearly correlated with the air gap size and could be employed as an indicator to evaluate clothing protective capabilities. Practical implications The findings suggested that greater attention should be paid to the protection and flexibility at the lower body and asymmetrical distribution of the air gap should be considered in the future air gap modeling. Originality/value The outcomes provided useful information to improve the protective clothing and develop more realistic air gap models to simulate the heat and mass transfer.

Motorcyclists are road users that highly exposed to hand-arm vibration that may contribute to body discomfort and fatigue that eventually will lead to road accidents and injuries. The two main objectives of this study are to identify the body parts that experience discomfort among motorcyclist and to understand the vibration exposure effect on different road types. In this study, two research methodologies were used; first, a survey questionnaire of 100 motorcyclists and second, an experimental study on hand-arm vibration (HAV) measurement exposed on motorcyclist using accelerometer mounted on the right side handlebars of the motorcycle. Two male respondents with a different weight range, 45-65 kg and >70 kg are selected for this experiment. The experiment was conducted on two different types of roads: tarmac road and pave road within a speed limit of 20-40 m/s2. Results of the study showed that the motorcyclist usually experienced body discomfort at lower back, upper back, wrist, buttock and neck area. The root-mean-square (r.m.s) frequency-weighted acceleration on the handlebars of the motorcycles was in the range of 0.07 m/s r.m.s for the tarmac road and 0.42 m/s r.m.s for the pave road. This value shows that different road type is affecting the vibration exposed to the motorcyclist. Clearly there’s a vibration felt by the motorcyclist but not on the degree of causing pain but a prolonged exposure to this vibration may induce discomfort and injuries.
