Aim: To identify the demographics and risk factors in a selected patient population prescribed non-selective and cyclo-oxygenase-2 (COX- 2) selective non-steroidal anti-inflammatory drugs (NSAIDs). Method: A structured clinical self-audit form was distributed in January to March 2001 to 155 interested general practitioners (GPs) in rural Queensland. Results: Seventy one GPs participated in the audit and contributed 1417 patient records - 790 patients had received nonselective NSAIDs and 627 had received COX-2 inhibitors (celecoxib or rofecoxib). Patients who received COX-2 inhibitors were significantly older, more likely to have clinically important concomitant illness, and more likely to be taking medication known to interact with NSAIDs. They were also twice as likely to have two or more risk factors for adverse effects. The most common reasons for switching from an NSAID to a COX-2 inhibitor were reported to be a previous side effect from an NSAID (primarily related to gastrointestinal effects) or the doctor's perception of the superior efficacy of COX-2 inhibitor therapy. Conclusions: This study has shown that COX-2 inhibitors were used in a distinctly different patient population compared to non-selective NSAIDs. There were significant variations in the demographics and number of risk factors - for example, cardiovascular and renal - between the two identified populations. These differences may be due to doctors selecting COX-2 inhibitors for patients at high risk of gastrointestinal complications. However, the prescribing pattern may also be partly due to misconceptions about the relative safety and efficacy of COX-2 inhibitor drugs.

Lobular carcinoma in situ was first described over 60 years ago. Despite the long history, it continues to pose significant difficulties in screening, diagnosis, management and treatment. This is partly due its multi-focal and bilateral presentation, an incomplete understanding of its biology and natural history and perpetuation of misconceptions gathered over the last decades. In this review, the working group on behalf of EUSOMA has attempted to summarise the current thinking and management of this interesting lesion. (c) 2006 Elsevier Ltd. All rights reserved.

Este trabalho de pesquisa faz uma abordagem não exaustiva acerca da temática da liberdade na perspectiva da teóloga cristã protestante norte-americana Ellen G. White, partindo do estudo de sua pessoa e dos contextos geopolítico e sociocultural nos quais viveu, avançando ainda para uma noção de sua produção literária e a importância da sistematização de seu pensamento para uma compreensão de sua tratativa quanto ao tema proposto. Toma-se como critério de análise a organização de seu pensamento em três linhas de raciocínios teológicos chamadas, respectivamente, Teologia Integral, Teologia do Compromisso e Teologia do Discipulado, as quais, combinadas, constituem sua perspectiva teológica de liberdade. Mostra-se que a primeira linha justifica as razões da liberdade, a segunda explica como ela ocorre no ser humano, e a terceira propõe o roteiro de sua exteriorização positiva para a humanidade. Segue-se, então, examinando os conceitos, fundamentos, características e desdobramentos temáticos de cada um dos elementos constituintes dos roteiros teológicos mencionados, evidenciando os teólogos que mais influenciaram a autora e apontando as aproximações de sua perspectiva à de teólogos que lhe são posteriores. Em conclusão, propõe-se, na perspectiva da autora, liberdade como expressão significante de uma vida comprometida com o servir em amor de forma piedosa. Liberdade é, assim, uma condição experimentada por aqueles que creem e se submetem a Deus, experimentando uma vida de permanente amor e serviço abnegado ao próximo, realidade testemunhada na prática da genuína piedade cristã. E, por último, desafia-se o leitor à urgente percepção, crítica e reação proativa equilibrada em relação às ideologias humanistas de matriz antropocêntrica exclusiva, mostrando-as como principais fundamentos dos equívocos (pós)modernos de liberdade. Diante dessa realidade, propõe-se a reumanização da ideia de liberdade numa perspectiva teocêntrica por meio do retorno a Deus e à Sua Palavra, empreendimento para o qual a proposta de Ellen G. White se mostra um potencial Teo-humanizador de considerável valor, capaz de possibilitar inclusive o desenvolvimento harmônico da integralidade humana.

Purpose - This paper provides a deeper examination of the fundamentals of commonly-used techniques - such as coefficient alpha and factor analysis - in order to more strongly link the techniques used by marketing and social researchers to their underlying psychometric and statistical rationale. Design/methodology approach - A wide-ranging review and synthesis of psychometric and other measurement literature both within and outside the marketing field is used to illuminate and reconsider a number of misconceptions which seem to have evolved in marketing research. Findings - The research finds that marketing scholars have generally concentrated on reporting what are essentially arbitrary figures such as coefficient alpha, without fully understanding what these figures imply. It is argued that, if the link between theory and technique is not clearly understood, use of psychometric measure development tools actually runs the risk of detracting from the validity of the measures rather than enhancing it. Research limitations/implications - The focus on one stage of a particular form of measure development could be seen as rather specialised. The paper also runs the risk of increasing the amount of dogma surrounding measurement, which runs contrary to the spirit of this paper. Practical implications - This paper shows that researchers may need to spend more time interpreting measurement results. Rather than simply referring to precedence, one needs to understand the link between measurement theory and actual technique. Originality/value - This paper presents psychometric measurement and item analysis theory in easily understandable format, and offers an important set of conceptual tools for researchers in many fields. © Emerald Group Publishing Limited.

This thesis is organised into four parts. In Part 1 relevant literature is reviewed and presented in three chapters. Chapter 1 examines legal and cultural factors in identifying the. boundaries of rape. Chapter 2 discusses idiographic features· and causal characteristics of rape suspects and victims. Chapter 3 reviews the evidence relating to attitudes toward rape,. attribution of responsibility to victims and the routine management of rape cases by the police. Part II comprises an experimental investigation of observer perception of the victims of violent crime. The experiment, examined the processes by which impressions were attributed to victims of personal crime. The results suggested that discrepancies from observers' stereotypes were an important factor in their polarisation of victim ratings. The relevance of. examining . both the structure and process of' impression, formation was highlighted. Part III describes an extensive field study in which the West. Midlands police files on rape for an eight year period (1071-1978) were analysed. The study revealed a large number of interesting findings related to a wide range of relevant features of the crime. Further, the impact .of common misconceptions and "myths" of rape were investigated across the legal and judicial processing of rape cases. The evidence suggests that these "myths" lead·to differential biasing effects at different stages in the process. In the final part of this thesis,. salient issues raised by the experiment and field study .are discussed·within the framework outlined in Part 1. Potential implications for future developments and research: are presented.

Aims The aims of this study were to examine Type 2 diabetic patients' expectations, perceptions and experiences of oral glucose-lowering agents (OGLAs), including their reasons for taking/not taking these drugs as prescribed and to provide recommendations for developing interventions to improve OGLA adherence. Methods Longitudinal, qualitative study using repeat in-depth interviews with patients (n = 20) over 4 years following clinical diagnosis. Respondents were recruited from primary and secondary care settings across Lothian, Scotland, UK. Results Despite experiences of side-effects, dislikes and concerns about taking multiple drugs and a belief that OGLAs could themselves cause one's diabetes to progress, most respondents appeared motivated to take these drugs as prescribed. This motivation seemed to arise from respondents' experiences of taking OGLAs and observing them to 'work'. Some respondents described feeling better after taking OGLAs, others, typically those who were asymptomatic, used blood glucose self-monitoring and/or glycated haemoglobin results to observe and evidence the effects of their OGLAs. Most respondents demonstrated a 'passive' expectation that health professionals should be responsible for decisions about medications. Hence, non-adherence typically resulted from forgetfulness rather than ambivalence about either medication or consultation style. Respondent concern about OGLA's largely centred upon lack of knowledge about the medication and what to do when doses were missed. Conclusion The findings call for multifaceted strategies to promote adherence. These could include education to address misconceptions and advise patients how to respond to missed doses; reminders to help patients remember to take their drugs; and structured feedback on the impact of OGLAs on glycaemic control.

The increasing need for maintenance, repair, and overhaul (MRO) organizations to meet customers' demands in quality and reduced lead times is key to its survival within the aviation industry. Furthermore, with the unpredictability in the global market and difficulties with forecasting characteristic of the MRO industry there is an increased need for the reevaluation of the operation models of organizations within this sector. However, severe economic turmoil and ever-increasing global competition introduce the opportunity for the adoption of a resilient, tried, and tested business operation model such as 'Lean'. In order to understand this concept, its long-term viability, and its application within the aerospace MRO sector fully, this paper presents the state-of-the-art in terms of the adoption of Lean within the MRO industry by carrying out a systematic review of the literature. This paper establishes the common perception of Lean by the MRO industry and the measurable progress that has been made on the subject. Some issues and challenges are also highlighted including the misconceptions that arise from the direct transference of the perception of Lean from other industrial sectors into the aerospace MRO industry. The 'enablers and inhibitors' of Lean within the aviation industry are also discussed. This paper exposes the scarcity of the literature and the general lagging behind of the industry to the adoption of the Lean paradigm and thus highlights areas where further research is required. © 2011 Authors.

Background: Stereotypically perceived to be an ‘all male’ occupation, engineering has for many years failed to attract high numbers of young women [1,2]. The reasons for this are varied, but tend to focus on misconceptions of the profession as being more suitable for men. In seeking to investigate this issue a participatory research approach was adopted [3] in which two 17 year-old female high school students interviewed twenty high school girls. Questions focused on the girls’ perceptions of engineering as a study and career choice. The findings were recorded and analysed using qualitative techniques. The study identified three distinctive ‘influences’ as being pivotal to girls’ perceptions of engineering; pedagogical; social; and, familial. Pedagogical Influences: Pedagogical influences tended to focus on science and maths. In discussing science, the majority of the girls identified biology and chemistry as more ‘realistic’ whilst physics was perceived to more suitable for boys. The personality of the teacher, and how a particular subject is taught, proved to be important influences shaping opinions. Social Influences: Societal influences were reflected in the girls’ career choice with the majority considering medical or social science related careers. Although all of the girls believed engineering to be ‘male dominated’, none believed that a woman should not be engineer. Familial Influences: Parental influence was identified as key to career and study choice; only two of the girls had discussed engineering with their parents of which only one was being actively encouraged to pursue a career in engineering. Discussion: The study found that one of the most significant barriers to engineering is a lack of awareness. Engineering did not register in the girls’ lives, it was not taught in school, and only one had met a female engineer. Building on the study findings, the discussion considers how engineering could be made more attractive to young women. Whilst misconceptions about what an engineer is need to be addressed, other more fundamental pedagogical barriers, such as the need to make physics more attractive to girls and the need to develop the curriculum so as to meet the learning needs of 21st Century students are discussed. By drawing attention to the issues around gender and the barriers to engineering, this paper contributes to current debates in this area – in doing so it provides food for thought about policy and practice in engineering and engineering education.

This study examines the state of academic research in selling and sales management (S&SM) from the years 2003-7, ten years after the data collected by Moncrief, Marshall, and Watkins (2000). Sales articles are reviewed that appeared in 19 marketing journals and evidence is provided on the state of the S&SM discipline by comparing the number of authors, authorships, and publications versus a comparable five-year period a decade ago. Of interest are the universities that produce and employ faculty in S&SM and to identify those schools and geographic regions that are publishing the majority of articles. Publication distribution trends across journals are also examined. A dramatic increase in non-U.S. authors and authorships is noted versus the prior study. Overall, the findings indicate that, perhaps contrary to some popular misconceptions, the state of S&SM research is healthy, vibrant, and evolving.

Differential clinical diagnosis of the parkinsonian syndromes,viz., Parkinson's disease (PD), progressive supranuclear palsy (PSP), dementia with Lewy bodies (DLB), multiple system atrophy (MSA), and corticobasal degeneration (CBD) can be difficult. Visual hallucinations, however, are a chronic complication of some parkinsonian disorders and their presence may be a useful aid to diagnosis. The visual hallucinations in parkinsonism are often recurrent, well-formed, and detailed and occur in a significant proportion of cases of DLB and PD but are less common in PSP, MSA, and CBD. Hallucinations in PD often occur later in the disease and are complex, with flickering lights, and illusionary misconceptions often preceding the most common manifestation, viz., stereotypical colourful images. Hallucinations in DLB, however, are often present earlier in the disease and are similar to those in the 'misidentification syndromes', 'visual agnosias', and in 'delerium' but differ from those produced by hallucinogenic drugs such as LSD. Most typically in DLB, the hallucinations involve people or animals invading the patient's home but may also include inanimate objects and the appearance of writing on walls or ceilings. Visual hallucinations may involve a number of brain mechanisms including a change in the balance of neurotransmitter activity between the cholinergic and monoaminergic systems and may be a specific consequence of Lewy body (LB) pathology in brain stem nuclei. Ocular and retinal pathology may also contribute to hallucinations by reducing occipital stimulation. Hence, in patients with unclassifiable or with indeterminate parkinsonian symptoms, the presence of visual hallucinations should be regarded as a 'red flag' symptom indicating underlying Lewy body pathology and therefore, supporting a diagnosis of PD or DLB rather than PSP, MSA, or CBD. The presence of early visual hallucinations would support a diagnosis of DLB rather than PD. © 2013 Nova Science Publishers, Inc. All rights reserved.
