External audit in the National Health Service in England and Wales:a study of an oversight body's control of auditor remuneration

In the National Health Service (NHS) in England and Wales an oversight body, the Audit Commission (AC), defines the scope of the external auditors’ work, appoints the auditors and has oversight of their fees and audit quality. This heavily regulated audit regime mitigates some of the deficiencies observed in high profile corporate failures. Independence, it has been argued, is influenced by the total auditor remuneration paid by the client. In this study we examine total auditor remuneration in a regulated market which seeks to ensure audit independence and audit quality. In particular we undertake rigorous analysis of auditor remuneration by the type of auditor: We place emphasis on the differentiation between private sector firms and the AC’s in-house auditors (District Audit). Individual private audit firms charge premiums (up to 16%) for particular audit work in identified locations, but no premiums were found when we examined total auditor remuneration. The regime appears to permit efficient operation of the audit market while safeguarding both audit independence and standards.

Investigating the role of capacitive coupling between the operating table and the return electrode of an electrosurgery unit in the modification of the current density distribution within the patients’ body

Background: Electrosurgery units are widely employed in modern surgery. Advances in technology have enhanced the safety of these devices, nevertheless, accidental burns are still regularly reported. This study focuses on possible causes of sacral burns as complication of the use of electrosurgery. Burns are caused by local densifications of the current, but the actual pathway of current within patient's body is unknown. Numerical electromagnetic analysis can help in understanding the issue. Methods: To this aim, an accurate heterogeneous model of human body (including seventy-seven different tissues), electrosurgery electrodes, operating table and mattress was build to resemble a typical surgery condition. The patient lays supine on the mattress with the active electrode placed onto the thorax and the return electrode on his back. Common operating frequencies of electrosurgery units were considered. Finite Difference Time Domain electromagnetic analysis was carried out to compute the spatial distribution of current density within the patient's body. A differential analysis by changing the electrical properties of the operating table from a conductor to an insulator was also performed. Results: Results revealed that distributed capacitive coupling between patient body and the conductive operating table offers an alternative path to the electrosurgery current. The patient's anatomy, the positioning and the different electromagnetic properties of tissues promote a densification of the current at the head and sacral region. In particular, high values of current density were located behind the sacral bone and beneath the skin. This did not occur in the case of non-conductive operating table. Conclusion: Results of the simulation highlight the role played from capacitive couplings between the return electrode and the conductive operating table. The concentration of current density may result in an undesired rise in temperature, originating burns in body region far from the electrodes. This outcome is concordant with the type of surgery-related sacral burns reported in literature. Such burns cannot be immediately detected after surgery, but appear later and can be confused with bedsores. In addition, the dosimetric analysis suggests that reducing the capacity coupling between the return electrode and the operating table can decrease or avoid this problem. © 2013 Bifulco et al.; licensee BioMed Central Ltd.

The body matters: Understanding social differences in mental health

This doctoral dissertation illuminates the salience of body image to sociological investigations of mental health. It is argued that concerns over body-appearance evident in America embody a dimension of distress over the physical self that may be appropriately considered a mental health outcome, called body dysphoria. Using cross-sectional data on 1,183 young adults comprising Hispanic, African American, and non-Hispanic white males and females from varying social classes, a valid and reliable measure of body dysphoria is developed and demonstrated to be a distinct dimension of psychological distress. ^ From the standpoint of the sociology of mental health, the social distribution of body dysphoria makes known individual consequences of the stratified arrangements of society based on gender, race/ethnicity, and social class. Results reveal significant social differences in body dysphoria that are both consistent with and contrary to clinical studies attributing eating disorders to white, upper-class females. Body dysphoria is substantially greater among females supporting that unrealistic cultural ideals and standards of body-appearance remain disproportionately targeted at females in the development and presentation of self. Compared to non-Hispanic whites, Hispanics exhibit higher average levels of body dysphoria while African Americans exhibit lower levels of comparable proportion. The question is addressed whether identification with the dominant (white) culture influences distress over body-appearance among racial/ethnic minorities. A small inverse association is revealed between social class origin and body dysphoria suggesting that individuals from lower social class backgrounds are as greatly affected by body image concerns generally presumed to preoccupy upper social classes. ^ The stress process is a widely used theoretical paradigm for explaining structurally driven social differences in mental health outcomes. New evidence is introduced that the stress process may contribute to understanding body image problems. Regression analyses reveal that stress exposure has a significant positive association with body dysphoria that is mediated by varying psychosocial resources. Overall, the stress process explains the effects of social class origin and African American race/ethnicity on body dysphoria but does not account for the larger effects of being female or Hispanic. ^

The influence of body size on the ecology of coastal fish predators in the Bahamas

Body size is a fundamental structural characteristic of organisms, determining critical life history and physiological traits, and influencing population dynamics, community structure, and ecosystem function. For my dissertation, I focused on effects of body size on habitat use and diet of important coastal fish predators, as well as their influence on faunal communities in Bahamian wetlands. First, using acoustic telemetry and stable isotope analysis, I identified high variability in movement patterns and habitat use among individuals within a gray snapper (Lutjanus griseus) and schoolmaster snapper (L. apodus) population. This intrapopulation variation was not explained by body size, but by individual behavior in habitat use. Isotope values differed between individuals that moved further distances and individuals that stayed close to their home sites, suggesting movement differences were related to specific patterns of foraging behavior. Subsequently, while investigating diet of schoolmaster snapper over a two-year period using stomach content and stable isotope analyses, I also found intrapopulation diet variation, mostly explained by differences in size class, individual behavior and temporal variability. I then developed a hypothesis-testing framework examining intrapopulation niche variation between size classes using stable isotopes. This framework can serve as baseline to categorize taxonomic or functional groupings into specific niche shift scenarios, as well as to help elucidate underlying mechanisms causing niche shifts in certain size classes. Finally, I examined the effect of different-sized fish predators on epifaunal community structure in shallow seagrass beds using exclusion experiments at two spatial scales. Overall, I found that predator effects were rather weak, with predator size and spatial scale having no impact on the community. Yet, I also found some evidence of strong interactions on particular common snapper prey. As Bahamian wetlands are increasingly threatened by human activities (e.g., overexploitation, habitat degradation), an enhanced knowledge of the ecology of organisms inhabiting these systems is crucial for developing appropriate conservation and management strategies. My dissertation research contributed to this effort by providing critical information about the resource use of important Bahamian fish predators, as well as their effect on faunal seagrass communities.

Re-mapping the body: feminine experience in music performance

In this project report I analyse how the practice of Body Mapping impacts the bodily performances of women classical musicians. The purpose is to study how the characteristics that define normative gender affect the body and its movement; to interrogate the body as the site where a patriarchal society constructs gender roles (more specifically, femininity); and consequently to assess the effects that these may produce in music performance. Drawing on interviews with six women classical musicians, autoethnography, and Body Mapping as a method, I created a workbook for women Body Mapping students. The goal of my research is to look into the possibilities of how the three fields—music performance, Body Mapping and feminist thought—can connect together, thus laying the groundwork for possible future research in this area. Even more, I seek to apply new approaches to music performance and to contribute, at a practical level, to the development of women classical musicians.

‘Do you want to see my hornpipe?’: the traditional Irish dancing body at play in the work of Jean Butler and Colin Dunne’, in Anthony Shay and Barbara Sellers-Young (eds.), The Oxford Handbook of Dance and Ethnicity, Oxford: Oxford University Press, 2016, pp.41-65.

This chapter considers the radical reimaginings of traditional Irish step dance in the recent works of Jean Butler and Colin Dunne, in which the Irish step-dancing body is separated from its historical roots in nationalism, from the exhibitionism required by the competitive form, and from the spectacularization of the commercialized theatrical format. In these works the traditional form undergoes a critical interrogation in which the dancers attempt to depart from the determinacy of the traditional technique, while acknowledging its formation of their corporealities; the Irish step-dance technique becomes a springboard for creative experimentation. To consider the importance of the creative potential revealed by these works, this chapter contextualizes them within the dance background from which they emerged, outlining the history of competitive step dancing in Ireland, the “modernization” of traditional Irish dance with the emergence of Riverdance (1994), and the experiments of Ireland’s national folk theater, Siamsa Tíre.

Influence of environmental variability and age on the body condition of small pelagic fish in the Gulf of Lions

Endogenous and environmental variables are fundamental in explaining variations in fish condition. Based on more than 20 yr of fish weight and length data, relative condition indices were computed for anchovy and sardine caught in the Gulf of Lions. Classification and regression trees (CART) were used to identify endogenous factors affecting fish condition, and to group years of similar condition. Both species showed a similar annual cycle with condition being minimal in February and maximal in July. CART identified 3 groups of years where the fish populations generally showed poor, average and good condition and within which condition differed between age classes but not according to sex. In particular, during the period of poor condition (mostly recent years), sardines older than 1 yr appeared to be more strongly affected than younger individuals. Time-series were analyzed using generalized linear models (GLMs) to examine the effects of oceanographic abiotic (temperature, Western Mediterranean Oscillation [WeMO] and Rhone outflow) and biotic (chlorophyll a and 6 plankton classes) factors on fish condition. The selected models explained 48 and 35% of the variance of anchovy and sardine condition, respectively. Sardine condition was negatively related to temperature but positively related to the WeMO and mesozooplankton and diatom concentrations. A positive effect of mesozooplankton and Rhone runoff on anchovy condition was detected. The importance of increasing temperatures and reduced water mixing in the NW Mediterranean Sea, affecting planktonic productivity and thus fish condition by bottom-up control processes, was highlighted by these results. Changes in plankton quality, quantity and phenology could lead to insufficient or inadequate food supply for both species.

Factors Affecting the Body Mass Index in Adolescents in Portuguese Schools

The prevalence of overweight and obesity among children is increasing; hence, it was aimed to assess the Body Mass Index (BMI) in school children aged from 10 to 18 years for girls and to 17 for boys, as well as to identify the factors influencing BMI. This study included 742 students who answered a questionnaire previously approved for application in schools. The results showed some sociodemographic factors associated with BMI classes: age, school year, practicing high competition sport, being federate in a sport or having a vegetarian diet. The educational factors associated with BMI classes included only seminars given at school by a nutritionist. Behavioural factors significantly associated with BMI included: learning in classes, playing in the open air, reading books or use of internet. As conclusion, the results demonstrated that several factors affect BMI, and hence some actions could be taken in order to change them so as to reduce the prevalence of overweight, namely reinforcing the role of school and a more active participation of nutritionists in the education of the adolescents.

Influence of rest interval duration on muscular power production in the lower-body power profile

There is a paucity of evidence-based support for the allocation of rest interval duration between incremental loads in the assessment of the load-power profile. We examined the effect of rest interval duration on muscular power production in the load-power profile and sought to determine if greater rest is required with increasing load (i.e., variable rest interval). Ten physically trained men completed 4 experimental conditions in a crossover balanced design. Participants performed jump squats across incremental loads (0-60 kg) on 4 occasions, with an allocated recovery interval of 1, 2, 3, or 4 minutes. The mean log-transformed power output at each load was used for comparison between conditions (rest intervals). Unloaded jump squats (0 kg) maximized power output at each condition. The maximal mechanical power output was 66.6 ± 6.5 W·kg (1 minute), 66.2 ± 5.2 W·kg (2 minutes), 67.1 ± 5.9 W·kg (3 minutes), and 66.2 ± 6.5 W·kg (4 minutes). Trivial or unclear differences in power output were observed between rest intervals at each incremental load. As expected, power declined per 10 kg increment in load, the magnitude of decrease was 13.9-14.5% (confidence limits [CL]: ±1.3-2.0%) and 13.4-14.6% (CL: ±2.4-3.9%) for relative peak and mean power, respectively, yet differences in power output between conditions were likely insubstantial. The prescription of rest intervals between loads that are longer than 1 minute have a likely negligible effect on muscular power production in the jump squat incremental load-power profile. Practitioners should select either a 1- to 4-minute rest interval to best accommodate the logistical constraints of their monitoring sessions.

The body in photography: an improvised performance with light

Considering the way light is integral to photography I draw on its paradoxical nature at sub atomic levels that describe how, when observed it changes. Taking a biocentric approach ; ‘A radical new view of reality: Life creates time, space, and the cosmos itself The farther we peer into space, the more we realize that the nature of the universe cannot be understood fully by inspecting spiral galaxies or watching distant supernovas. It lies deeper. It involves our very selves.’ (Lanza, 2009), I aim to clarify how embodied photographic practice can be explored through improvisational and performative discourse.
