Children's body image concerns and eating disturbance: a review of the literature

In recent years a large number of studies have examined body image concerns, and early symptoms of eating disturbance among children. However, to date there has been no synthesis or evaluation of these studies. The purpose of the present article is to review and evaluate the research that has examined body image concerns, and eating attitudes and behaviors among children 6 to 11 years of age. The instruments used to assess body image concerns and eating disturbance in children closely resemble those used with adolescents and adults. Overall, the psychometric data for these instruments are very good and there is sufficient evidence indicating that they can be used reliably and validly. In addition, similar variables to those studied in adolescent and adult samples have been found to be associated with children's body image concerns and early eating disturbance. These include gender, age, body mass index, race, sociocultural pressures, and self-concept. Our understanding of the development of body image concerns and eating disturbance in children is limited, however, by the fact that most of the research in this field has been based on cross-sectional data, and the studies have focused almost exclusively on weight-loss cognitions and behaviors.

Quality of life instruments for caregivers of patients with cancer : A review of their psychometric properties

The quality of life of caregivers of patients with cancer is an important construct given the substantial impact of caring on the physical, psychological, social, and financial well-being of caregivers. Moreover, caring for patients with cancer also affects family functioning and places burdens on caregivers. The reliability and validity of instruments used to assess the quality of life of caregivers of patients with cancer were reviewed to aid in the selection of the most appropriate measures For research and practice. MEDLINE (1980-2000) and c/NAHL (1982-2000) searches located relevant quality of life instruments using the keywords "cancer and quality of Iife" and "caregiver or spouse or partner." The search identified the following instruments: the Caregiver Quality of life Index-Cancer Scale, the 'Caregiver Quality of Life Index, the Quality of Life Tool, and the Quality of life Index-Cancer Version. Quality of life instruments developed specifically to measure the quality of life of caregivers of patients with cancer had the best psychometric properties. The Caregiver Quality of Life Index-Cancer Scale, in particular, met or exceeded minimum psychometric criteria for reliability and validity. The development of reliable and valid caregiver quality of life measures is an important factor in developing interventions to enhance quality of life of caregivers of patients with cancer.

Global review of permian Tyloplecta muir-wood and cooper, 1960 (Brachiopoda): morphology, palaeobiogeographical and palaeogeographical implications

A global review of the stratigraphical and geographical distribution of Tyloplecta reveals that the genus ranges in age from Kungurian to Changhsingian (Middle to Late Permian). Tyloplecta first evolved in South China in the Kungurian (late Early Permian). The genus went through its first diversification in the Guadalupian, suffered a major extinction at the end of the Guadalupian, and re-diversified in the Wuchiapingian. T. yangtzeensis persisted into the Changhsingian as the only survivor of the genus involved in the end-Permian mass extinction. Palaeogeographically, South China is not only the centre of origin for the genus but also an area of diversification and evolution. In addition to South China, Tyloplecta has also been recorded from the Far East Russia, Japan, central Thailand, Laos, Cambodia, Qiangtang Terrane of Tibet, Salt Range, Iran, Armenia, Hungary, Yugoslavia, and Slovenia. This geographic spread suggests that Tyloplecta was primarily restricted to the Palaeotethys and is indicative of warm-water palaeoequatorial conditions. Its presence in some of the northeast Asian terranes (e.g., parts of Japan and Far East Russia) and in the Salt Range (Pakistan) and central and north Iran (part of the Cimmerian microcontinents) demonstrate that the genus invaded the middle palaeolatitudinal regions in both hemispheres during the late Middle Permian in response to increased shallow marine biotic communications between Cathaysia in the eastern Palaeotethys and southern Angaraland, and between Cathaysia and Peri-Gondwanaland. The invasion of Tyloplecta (and some other taxa) into the southern shore waters of Angaraland may be explained by assuming ocean surface current connections and close palaeogeographical proximities between the South China, Sino-Korea and Bureya blocks. In comparison, the invasion of Tyloplecta into the Peri-Gondwanaland region is more likely a result of reduced palaeogeographical distance between South China and Peri-Gondwanaland and the appearance of the Cimmerian microcontinents as migratory stepping stones.

Body image dissatisfaction among males across the lifespan- a review of past literature

Objective: Most past research has focused on body dissatisfaction among females. This paper provides a review and evaluation of studies that have examined body dissatisfaction among males. Body dissatisfaction in males has been associated with poor psychological adjustment, eating disorders, steroid use, exercise dependence, as well as other health behaviors. It is therefore important to understand the level of body dissatisfaction, as well as the factors that are related to this construct. Method: The review is divided into three sections: body dissatisfaction among children, adolescents and adults. Within each section, levels of body dissatisfaction are examined, as well as the research that relates to sociocultural influences on body dissatisfaction. Difficulties in drawing valid conclusions from the data due to methodological problems are highlighted. Results: From the current data, it would appear that there are strong similarities in the levels of body dissatisfaction of male and female children, with most children demonstrating high levels of body satisfaction. During adolescence, boys are about equally divided between wanting to lose weight and increasing weight, but there are few studies that have examined a desire for increased muscle size. In adulthood, men evidence a stronger desire to lose weight as they get older. Conclusion: Overall, past studies have primarily focused on questions that are relevant to females, and there is a need to conduct studies that evaluate areas of body dissatisfaction that have greater relevance for males. This will then allow a better understanding of the relationship between body dissatisfaction and psychological and behavioral problems experienced by males at all stages of the lifespan.

Does successful treatment of constipation or faecal impaction resolve lower urinary tract symptoms? A structured review of the literature

Consensus guidelines advocate the treatment of constipation and faecal impaction in order to improve symptoms of urinary frequency, urgency and urinary incontinence and to promote bladder emptying in the absence of urinary tract obstruction. This structured review of the literature was undertaken to search for and appraise evidence to support or negate the hypothesis of this relationship. The search strategy was comprehensive and identified six relevant studies. Two of these had been conducted on an adult population and four studies involved children with constipation. These studies were appraised for methodological quality. It was found that sample sizes were small and evidence was inconsistent. Variable methods of reporting meant that data were not able to be pooled for meta-analysis.
Based on the limited and conflicting evidence, it is recommended that further research be undertaken to identify any correlation between bowel and bladder function.

Gait termination : a review of experimental methods and the effects of aging and gait pathologies

The study of human gait has expanded and diversified to the extent that it is now possible to identify a substantive literature concerning a variety of gait tasks, such as gait initiation [Halliday SE, Winter DA, Frank JS, Patla AE, Prince F. The initiation of gait in young, elderly, and Parkinson's disease subjects. Gait Posture 1998;8:8–14; Mickelborough J, van der Linden ML, Tallis RC, Ennos AR. Muscle activity during gait initiation in normal elderly people. Gait Posture 2004;19:50–57], stepping over and across obstacles [Patla AE, Prentice SD, Robinson C, Newfold J. Visual control of locomotion: strategies for changing direction and for going over obstacles. J Exp Psych 1991;17:603–34; Chen, HC, Ashton-Miller JA, Alexander NB, Schultz AB. Effect of age and available response time on ability to step over an obstacle. J Gerontol 1994;49:227–33; Sparrow WA, Shinkfield AJ, Chow S, Begg RK. Gait characteristics in stepping over obstacles. Hum Mov Sci 1996;15:605–22; Begg RK, Sparrow WA, Lythgo ND. Time-domain analysis of foot–ground reaction forces in negotiating obstacles. Gait Posture 1998;7:99–109; Patla AE, Rietdyk S. Visual control of limb trajectory over obstacles during locomotion: effect of obstacle height and width. Gait Posture 1993;1:45–60] negotiating raised surfaces such as curbs and stairs [Begg RK, Sparrow WA. Gait characteristics of young and older individuals negotiating a raised surface: implications for the prevention of falls. J Gerontol Med Sci 2000;55A:147–54; Mcfayden BJ, Winter DA. An integrated biomechanical analysis of normal stair ascent and descent. J Biomech 1988;21:733–44]. In addition, increasing research interest in age-related declines in gait that might predispose individuals to falls has engendered a very extensive literature concerning ageing effects on gait. While rapid locomotor adjustments are common in the course of daily activities there has been no previous review of the findings concerning gait adaptations when walking is terminated both rapidly and unexpectedly. The aims of this review were first, to summarise the key research findings and methodological considerations from studies of termination. The second aim was to demonstrate the effects of ageing and gait pathologies on termination with respect to the regulation of step characteristics, lower-limb muscle activation patterns and foot–ground reaction forces.

Conceptualising the requirements of CRM from an organisational perspective : a review of the literature

For an organisation to undertake a Customer Relationship Management (CRM) implementation program it needs to consider a multitude of requirements. Some authors have hinted at viewing CRM within a wider perspective than just  customer centric perspectives. The aim of this paper is to discuss the domain and conceptualise some of the requirements of CRM from an organisation’s point of view. However, CRM needs to be identified as the whole organisation, including its internal and external environments. Undertaking CRM in any organisation needs to be preceded by a sequence of stages. An organization needs to develop a roadmap outlining the path to become CRM centric. Therefore an organisation should address, or at least consider, a list of those factors at every stage of a CRM implementation program, for an implementation program to be effective. The main focus of literature in CRM has been customer centric. This paper, being the first stage of much wider research, will focus on the organisation and the internal environment. This paper will identify three information systems (IS) and information technology (IT) requirements in organisations that are integral parts of CRM. These need to achieve a level of synergy for successful CRM. To understand these three requirements (front-end systems, back-end systems, and datahandling technologies) in a CRM project is too great in magnitude at this early stage of the research. This paper begins to draw together the tenuous links between the three requirements of information systems (IS) and information technology (IT) systems. Writing this paper and shifting its focus towards requirements engineering, the author has realised that a whole area of literature has to be explored, because CRM is another IS implementation.

A brief review of PhDs in creative and performing arts in Australia

This paper reports on an aspect of a pilot project conducted in 2003 by the authors comprising a bibliographic analysis of all (approximately 51,000) Australian PhDs. The pilot work is both a data and methodological basis for a larger project that investigates the nature and development of PhDs in Australia as they evolved in the context of national economic, social and educational changes. This paper reviews the evidence from the bibliographic data held in library catalogues of PhDs in each Australian university. After considering the definitional properties and their operationalisation, the paper provides an overview of the first instances, locations and frequencies of PhDs in the creative and performing arts in Australia, fields which are relatively new to doctoral study and which pose challenges in terms of doctoral pedagogy and scholarship. This is contextualised in terms of the development of the contemporary university sector during the 1990s, including the growth in the creative and performing arts therein.

Teacher and peer assessment of creativity in technology education

This study, part of a PhD thesis, investigates a number of aspects relating to technology education, creativity and the assessment of creativity and aesthetics. Following tuitional sessions, panels of upper primary school children were involved in assessing the creative and aesthetic characteristics of technological products made by other children. Teachers assessed a selection of student drawings for creativity and these results were compared against the corresponding products assessed by the panels of Year 5 children. Subjects were administered a test on their knowledge of technology and these scores were compared to product creativity scores. The results showed high correlations between the assessor ranks for both creativity and aesthetics although there was generally more consistency with creativity. While some subjects produced both creative drawings and products, others showed creativity in only one outcome. A further finding of the investigation identified the relationship between students' knowledge of technology and the creative product constructed by the older children in the study.

Real time, perceived time and time online : a review of student experiences of time over thirty years of distance and online education

This paper examines how students use and perceive time when studying in distance education modes and what affects this perception of time and the reality of time. We examine 30 years of student involvement on distance and online education, their comments on both their learning experiences, and the technology requirements of distance education/online learning. Our University has been involved in distance education since its formation in 1974. The online technologies offer increasingly sophisticated and immersive experiences for our students, both on campus and off campus, but many of our students continue to complain of time squeeze, and fail to predict the time it will take them to complete our subjects. We research how the technologies we use for online learning are contributing to this time squeeze perception and the student's "real" time to learn.
Research is drawn from both the Australian Bureau of Statistics and surveys of our students' experiences (we have 32,000 students online, with single online classes of over 1300 students), to examine student use and perceptions of their available time to study and how the technologies used in online learning affect this.

Managing in the middle: a review of the mddle management experience in the 21st century

Downsizing and organisational restructuring have impacted both the role and the number of middle managers in organisations. .This paper provides a review of recent research on middle management to seek an understanding of the current situation for middle managers as they face the start of the 2rt century. The literature review is presented in two parts - focusing on the position of middle managers as they emerge from downsizing, and drawing attention to the special circumstances for managers "in the middle". The research points to some of the challenges middle managers' experience as they work, live, and survive organisational life, as well as highlighting the need for ongoing investigation of their individual experiences.

Who are "innovators" and do they matter?: A critical review of the evidence supporting the targeting of “innovative” consumers

Purpose – This paper aims to bring together and evaluate the reasons that have historically been advanced to justify the heavy emphasis on innovative consumers within the general context of the adoption of products and services, and to assess the strategic benefits to be gained from targeting such market segments.

Design/methodology/approach – The approach is critical review and analysis of the published
literature.

Findings – This paper finds that, although the benefits of identifying innovative early adopters are not as strong and clear-cut as is often claimed, they are still sufficient to warrant further research into methods that will accurately identify them and predict their purchasing behaviour.

Practical implications – Targeting strategies should distinguish carefully between truly innovative consumers and other early adopters. The costs of identifying them in a particular market need to be weighed against the potential benefits.

Originality/value – Although many studies have attempted to address the question of what drives individual adoption behaviour, the rationale for that focus has not been well established and is rarely critiqued. In clarifying the situation, this paper should provide guidance for academic researchers and marketing planners.

A review of international human resource management : integration, interrogation, imitation

International human resource management (IHRM) represents an important dimension of international management. Over the past three decades, there has been considerable growth in research and practice in IHRM. While there have been extensive developments in this field, numerous scholars have identified aspects requiring review and revision. Hence, this paper reviews and interrogates the progress in IHRM's theoretical development. The review leads to the conclusion that research in IHRM has tended to emphasize integration over other forms of progress. In response, and in provocation, imitation rather than integration is suggested as an approach for the development of future theoretical and conceptual directions in IHRM.

Strategies which aim to positively impact on weight, physical activity, diet and sedentary behaviours in children from zero to five years. A systematic review of the literature

Preventing the development of obesity in children is an international health priority. To assess the effectiveness of interventions designed to prevent obesity, promote healthy eating and/or physical activity and/or to reduce sedentary behaviours in 0–5-year-old children, a systematic review of the literature was performed. Literature searches were limited to articles published between January 1995 and June 2006, printed in English and sampling children aged 0–5-years. Searches excluded literature concerned with breastfeeding, eating disorders, and interventions which were school-based or concerned with obesity treatment. Two reviewers independently extracted data and assessed study strengths and weaknesses. Nine included studies were grouped based on the settings in which they were delivered. Most studies involved multi-approach interventions, were conducted in the USA and varied in study designs and quality. All showed some level of effectiveness on at least one obesity-behaviour in young children. These studies support, at a range of levels, the premise that parents are receptive to and capable of some behavioural changes that may promote healthy weight in their young children. The small quantity of research heralds the need, particularly given the potential for early intervention to have long-lasting impacts on individual and population health, to build in a substantial way upon this evidence base.
