Prediction of total body water in infants and children

Background: In paediatric clinical practice treatment is often adjusted in relation to body size, for example the calculation of pharmacological and dialysis dosages. In addition to use of body weight, for some purposes total body water (TBW) and surface area are estimated from anthropometry using equations developed several decades previously. Whether such equations remain valid in contemporary populations is not known. Methods: Total body water was measured using deuterium dilution in 672 subjects (265 infants aged < 1 year; 407 children and adolescents aged 1-19 years) during the period 1990-2003. TBW was predicted (a) using published equations, and (b) directly from data on age, sex, weight, and height. Results: Previously published equations, based on data obtained before 1970, significantly overestimated TBW, with average biases ranging from 4% to 11%. For all equations, the overestimation of TBW was greatest in infancy. New equations were generated. The best equation, incorporating log weight, log height, age, and sex, had a standard error of the estimate of 7.8%. Conclusions: Secular trends in the nutritional status of infants and children are altering the relation between age or weight and TBW. Equations developed in previous decades significantly overestimate TBW in all age groups, especially infancy; however, the relation between TBW and weight may continue to change. This scenario is predicted to apply more generally to many aspects of paediatric clinical practice in which dosages are calculated on the basis of anthropometric data collected in previous decades.

Electronic dance music culture and religion: An Overview

This article provides a comprehensive and critical overview of existing research that investigates (directly and indirectly) the religio-spiritual dimensions of electronic dance music culture (EDMC) (from disco, through house, to post-rave forms). Studies of the culture and religion of EDMC are explored under four broad groupings: the cultural religion of EDMC expressed through 'ritual' and 'festal'; subjectivity, corporeality and the phenomenological dance experience (especially 'ecstasy' and 'trance'); the dance community and a sense of belonging (the 'vibe' and 'tribes'); and EDMC as a new 'spirituality of life'. Moving beyond the cultural Marxist approaches of the 1970s, which held youth (sub)cultural expressions as 'ineffectual' and 'tragic', and the postmodernist approaches of the early 1990s, which held rave to be an 'implosion of meaning', recent anthropological and sociological approaches recognise that the various manifestations of this youth cultural phenomenon possess meaning, purpose and significance for participants. Contemporary scholarship thus conveys the presence of religiosity and spirituality within contemporary popular cultural formations. In conclusion, I suggest that this and continuing scholarship can offer useful counterpoint to at least one recent account (of clubbing) that overlooks the significance of EDMC through a restricted and prejudiced apprehension of 'religion'.

Queer sex work

Sex work is a subject of significant contestation across academic disciplines, as well as within legal, medical, moral, feminist, political and socio-cultural discourses. A large body of research exists, but much of this focuses on the sale of sex by women to men and ignores other performances, practices, meanings and embodiments in the contemporary sex industry. A queer agenda is important in order to challenge hetero-centric gender norms and to develop new insights into how gender, sex, power, crime, work, migration, space/place, health and intimacy are understood in the context of commercial sexual encounters. Queer Sex Work explores what it might mean to 'be', 'do' and 'think' queer(ly) in the study and practice of commercial sex. It brings together a multiplicity of empirical case studies - including erotic dance venues, online sex working, pornography, grey sexual economies, and BSDM - and offers a variety of perspectives from academic scholars, policy practitioners, activists and sex workers themselves. In so doing, the book advances a queer politics of sex work that aims to disrupt heteronormative logics whilst also making space for different voices in academic and political debates about commercial sex. This unique and multidisciplinary volume will be indispensable for scholars and students of the global sex trade and of gender, sexuality, feminism and queer theory more broadly, as well as policymakers, activists and practitioners interested in the politics and practice of sex work in local, national and international contexts.

Effects of nutrition education on the nutrition knowledge of future aerobic dance instructors

The effectiveness of nutrition education on the nutrition knowledge of future aerobic instructors was studied. Forty-seven subjects participated in the study. The experimental group (n=31) chose to and paid for a two-hour per week session of structured nutrition education for four weeks, the control group (n=16) did not. A nutrition knowledge test was completed by all subjects before and after the intervention. Results were analyzed for relationships between subject's nutrition knowledge and age, gender, educational background, income, and body mass index. No significant differences were found between the groups. The results showed that prior to any formal nutrition education, fitness instructors in the experimental and control groups had low nutrition knowledge (8.06%±16.4% and 4.38%±4.12%, respectively). Post-intervention nutrition knowledge significantly improved (p

Musculoskeletal effects and injury risk in collegiate Indian classical and ballet dancers

Dancers of all forms often engage in aesthetic yet challenging movements. Their training, choreography, and performances require strength, stamina, flexibility, grace, passion, and emotion. Ballet and Bharatanatyam (an Indian classical dance form) dancers utilize two movements in each of their dance forms that are similar—a half-sitting pose and a full-sitting pose, both requiring external rotation of the legs and bending at the knee joints. The purpose of this study was to examine and compare the biomechanics of joint reaction forces and knee angles in both styles of dance for these particular poses. The study included nine female ballet dancers and seven female Bharatanatyam dancers. Hamstring and gastrocnemius flexibility were measured for each dancer. Knee angles, vertical peak forces, and moments were determined for dancers at the lowest point of their bending positions. Mann-Whitney U tests found significant differences in hamstring flexibility, right gastrocnemius flexibility, and knee angles for the full-sitting poses between ballet and Bharatanatyam dancers. No significant difference was found in the vertical peak forces as a ratio to total body weight and moments between the two styles of dance. Further research can be done to more directly assess a difference in injury risk between the ballet and Bharatanatyam dancers.

The Narrative Value of Dance Communication: "habitus", musicality and emotion

The richness of dance comes from the need to work with an individual body. Still, the body of the dancer belongs to plural context, crossed by artistic and social traditions, which locate the artists in a given field. We claim that role conflict is an essential component of the structure of collective artistic creativity. We address the production of discourse in a British dance company, with data that spawns from the ethnography ‘Dance and Cognition’, directed by David Kirsh at the University of California, together with WayneMcGregor-Random Dance. Our Critical Discourse Analysis is based on multiple interviews to the dancers and choreographer. Our findings show how creativity in dance seems to be empirically observable, and thus embodied and distributed shaped by the dance habitus of the particular social context.

Overlapping Notions of Self and Other: the Case of the Anabaptist Body

This paper examines the complex interrelations between notions of ͚“elf͛ and ͚Otheƌ͛ with regards to human bodies, taking as a case study the bodily experiences of Anabaptist Christians, both historically and in the present day. It first examines body practices and discourses through the lens of Anabaptist approaches to baptism and conscience and it relates these to the Foucauldian notion of care of the Self. It then looks at biopolitical relations between individuals and the state through an examination of oath-taking and anti-war protests. Finally, it discusses the roles of bodies and bodiliness in contemporary Anabaptist commemorative practices.
