Changes in disability, physical/mental health states and quality of life during an 8-Week multimodal physiotherapy programme in patients with chronic non-specific neck pain: A prospective cohort study

Aim The aim of this study was to analyse the effect of an 8-week multimodal physiotherapy programme (MPP), integrating physical land-based therapeutic exercise (TE), adapted swimming and health education, as a treatment for patients with chronic non-specific neck pain (CNSNP), on disability, general health/mental states and quality of life. Methods 175 CNSNP patients from a community-based centre were recruited to participate in this prospective study. Intervention: 60-minute session (30 minutes of land-based exercise dedicated to improving mobility, motor control, resistance and strengthening of the neck muscles, and 30 minutes of adapted swimming with aerobic exercise keeping a neutral neck position using a snorkel). Health education was provided using a decalogue on CNSNP and constant repetition of brief advice by the physiotherapist during the supervision of the exercises in each session. Study outcomes: primary: disability (Neck Disability Index); secondary: physical and mental health states and quality of life of patients (SF-12 and EuroQoL-5D respectively). Differences between baseline data and that at the 8-week follow-up were calculated for all outcome variables. Results Disability showed a significant improvement of 24.6% from a mean (SD) of 28.2 (13.08) at baseline to 16.88 (11.62) at the end of the 8-week intervention. All secondary outcome variables were observed to show significant, clinically relevant improvements with increase ranges between 13.0% and 16.3% from a mean of 0.70 (0.2) at baseline to 0.83 (0.2), for EuroQoL-5D, and from a mean of 40.6 (12.7) at baseline to 56.9 (9.5), for mental health state, at the end of the 8-week intervention. Conclusion After 8 weeks of a MPP that integrated land-based physical TE, health education and adapted swimming, clinically-relevant and statistically-significant improvements were observed for disability, physical and mental health states and quality of life in patients who suffer CNSNP. The clinical efficacy requires verification using a randomised controlled study design.

Women's progression to leadership: A project-based organisational perspective

This is a qualitative study of female underrepresentation in leadership roles in project-based organisations in Australia, specifically the construction and property development industries. Using a gender lens, the underlying structural and cultural barriers to women's advancement to leadership in those organisations was studied and, in particular, what challenges they face in their career advancement and what attempts they make to resolve those challenges. The findings show that the unique characteristics of project-based organisations, with their perpetual masculine work practices, embedded masculine logic, gender-based bias and masculine organisational culture, all maintain the pattern of underrepresentation of women.

Just say no? The influence of personal goals, beliefs, psychosocial adjustment, and parental relationships in drug use by adolescents

The study in its entirety focused on factors related to adolescents decisions concerning drug use. The term drug use is taken here to include the use of tobacco products, alcohol, narcotics, and other addictive substances. First, the reasons given for drug use (attributions) were investigated. Secondly, the influence of personal goals, the beliefs involved in decision making, psychosocial adjustment including body image and involvement with peers, and parental relationships on drug use were studied. Two cohorts participated in the study. In 1984, a questionnaire on reasons for drug use was administered to a sample of adolescents aged 14-16 (N=396). A further questionnaire was administered to another sample of adolescents aged 14-16 (N=488) in 1999. The results for both cohorts were analyzed in Articles I and II. In Articles III and IV further analysis was carried out on the second cohort (N=488). The research report presented here provides a synthesis of all four articles, together with material from a further analysis. In a comparison of the two cohorts it was found that the attributions for drug use had changed considerably over the intervening fifteen-year period. In relation to alcohol and narcotics use an increase was found in reasons involving inner subjective experiences, with mention of the good feeling and fun resulting from alcohol and narcotics use. In addition, the goals of alcohol consumption were increasingly perceived as drinking to get drunk, and for its own sake. The attributions for the adolescents own smoking behavior were quite different from the attributions for smoking by others. The attributions were only weakly influenced by the participants gender or by their smoking habits, either in 1984 or 1999. In relation to participants own smoking, the later questionnaire elicited more mention of inner subjective experiences involving "good feeling. In relation to the perceived reasons for other people s smoking, it elicited more responses connected with the notion of "belonging. In the second sample, the results indicated that the levels of body satisfaction among adolescent girls are lower than those among adolescent boys. Overall, dissatisfaction with one's physical appearance seemed to relate to drug use. Girls were also found to engage in more discussions than boys; this applied to (i) discussion with peers (concerning both intimate and general matters), and (ii) discussion with parents (concerning general matters). However, more than a quarter of the boys (out of the entire population) reported only low intimacy with both parents and peers. If both drinking and smoking were considered, it seemed that girls in particular who reported drinking and smoking also reported high intimacy with parents and peers. Boys who reported drinking and smoking reported only medium intimacy with parents and peers. In addition, having an intimate relationship with one's peers was associated with a greater tendency to drink purely in order to get drunk. Overall, the results seemed to suggest that drug use is connected with a close relationship with peers and (surprisingly) with a close relationship with parents. Nevertheless, there were also indications that to some extent peer relationships can also protect adolescents from smoking and alcohol use. The results, which underline the complexity of adolescent drug use, are taken up in the Discussion section. It may be that body image and/or other identity factors play a more prominent role in all drug use than has previously been acknowledged. It does appear that in the course of planning support campaigns for adolescents at risk of drug use, we should focus more closely on individuals and their inner world. More research on this field is clearly needed, and therefore some ideas for future research are also presented.

Research of Face Location System Based on Human Vision Simulations

In this paper we present a robust face location system based on human vision simulations to automatically locate faces in color static images. Our method is divided into four stages. In the first stage we use a gauss low-pass filter to remove the fine information of images, which is useless in the initial stage of human vision. During the second and the third stages, our technique approximately detects the image regions, which may contain faces. During the fourth stage, the existence of faces in the selected regions is verified. Having combined the advantages of Bottom-Up Feature Based Methods and Appearance-Based Methods, our algorithm performs well in various images, including those with highly complex backgrounds.

Canada/U.S. border crossing: facilitation and constraint

Abstract The aim of this research project is to draw on accounts of experiences ofborder crossing and regulation at the Canada/U.S. border at Niagara in order to illuminate the dynamics of differentiation and inequality at this site. The research is informed by claims that the world is turning into a global village due to transnational flows oftechnology, infonnation, capital and people. Much of the available literature on globalization shows that while the transfer of technology, information, and capital are enhanced, the transnational movement of people is both facilitated and constrained in complex and unequal ways. In this project, the workings of facilitation and constraint were explored through an analysis often interviews with people who had spent a substantial portion oftheir childhood (e.g. 5 years) in a Canadian border community. The interviewees were at the time ofthe research between the ages of 19 and 25. Because most ofthe respondents were 'white' Canadians of working to upper middle class status, my focus was to explore how 'whiteness' as privilege may translate into enhanced movement across borders and how 'white' people may internalize and enjoy this privilege but may often deny its reality. I was also interested in how inequality is perceived, understood, and legitimated by these relatively privileged people. My analysis ofthe ten accounts ofborder crossing and regulation suggests that differentially situated people experience border crossing differently. An important finding is that while relatively privileged border crossers perceived and often problernatized differential treatment based on external factors such as physical appearance, and especially race, most did not challenge such treatment but rather saw it as acceptable. These findings are located within newer literature that addresses the increasing securitization ofborders and migration in western societies.

Les déterminants du comportement alimentaire de jeunes hommes gais

Introduction : Cette étude visait à explorer les déterminants des choix alimentaires de jeunes hommes gais. L’objectif secondaire était d’explorer la perception des hommes gais à l’égard du comportement alimentaire des hommes hétérosexuels. Méthode : Une méthode qualitative s’appuyant sur la prise de photographies et d’entrevues individuelles semi-dirigées a été utilisée. Résultats : Onze hommes gais de 21 à 25 ans et habitant en appartement dans la région de Montréal ont participé à l’étude. L’apparence corporelle, la santé et la nutrition sont des facteurs très influents de leur comportement alimentaire. Les hommes de la cohorte soutiennent la perception que ces facteurs n’influencent pas aussi fortement le comportement alimentaire des hommes hétérosexuels. Ils sont de grands consommateurs de cuisine hors domicile. Plusieurs d’entre eux limitent leur consommation de viande, un aliment qu’ils considèrent masculin et fortement lié aux hommes hétérosexuels. Conclusion : Le comportement alimentaire des jeunes hommes de cette cohorte est influencé par plusieurs facteurs qui ne sont habituellement pas associés aux hommes, dont l’apparence corporelle, la santé et la nutrition. Ils sont au fait de cette dichotomie en se comparant à leurs proches hétérosexuels. Si les professionnels de la santé négligent ces facteurs, ils risquent de passer à côté de leviers d’intervention efficaces.

The use of FT-IR as a screening technique for organic residue analysis of archaeological samples

A range of archaeological samples have been examined using FT-IR spectroscopy. These include suspected coprolite samples from the Neolithic site of Catalhoyuk in Turkey, pottery samples from the Roman site of Silchester, UK and the Bronze Age site of Gatas, Spain and unidentified black residues on pottery sherds from the Roman sites of Springhead and Cambourne, UK. For coprolite samples the aim of FT-IR analysis is identification. Identification of coprolites in the field is based on their distinct orange colour; however, such visual identifications can often be misleading due to their similarity with deposits such as ochre and clay. For pottery the aim is to screen those samples that might contain high levels of organic residues which would be suitable for GC-MS analysis. The experiments have shown coprolites to have distinctive spectra, containing strong peaks from calcite, phosphate and quartz; the presence of phosphorus may be confirmed by SEM-EDX analysis. Pottery containing organic residues of plant and animal origin has also been shown to generally display strong phosphate peaks. FT-IR has distinguished between organic resin and non-organic compositions for the black residues, with differences also being seen between organic samples that have the same physical appearance. Further analysis by CC-MS has confirmed the identification of the coprolites through the presence of coprostanol and bile acids, and shows that the majority of organic pottery residues are either fatty acids or mono- or di-acylglycerols from foodstuffs, or triterpenoid resin compounds exposed to high temperatures. One suspected resin sample was shown to contain no organic residues. and it is seen that resin samples with similar physical appearances have different chemical compositions. FT-IR is proposed as a quick and cheap method of screening archaeological samples before subjecting them to the more expensive and time-consuming method of GC-MS. This will eliminate inorganic samples such as clays and ochre from CC-MS analysis, and will screen those samples which are most likely to have a high concentration of preserved organic residues.

Can physical exercise during gestation attenuate the effects of a maternal perinatal low-protein diet on oxygen consumption in rats?

A protocol of physical exercise, based on maximal oxygen uptake ((V) over dot(O2max)), for female rats before and during pregnancy was developed to evaluate the impact of a low-protein diet on oxygen consumption during gestation and growth rate of the offspring. Virgin female Wistar rats were divided into four groups as follows: untrained (NT, n = 5); trained (T, n = 5); untrained with low-protein diet (NT+LP, n = 5); and trained with low-protein diet (T+LP, n = 5). Trained rats were submitted to a protocol of moderate physical training on a treadmill over a period of 4 weeks (5 days week(-1) and 60 min day(-1), at 65% of (V) over dot(O2max)). At confirmation of pregnancy, the intensity and duration of the exercise was reduced. Low-protein groups received an 8% casein diet, and their peers received a 17% casein diet. The birthweight and growth rate of the pups up to the 90th day were recorded. Oxygen consumption ((V) over dot(O2)), CO(2) production and respiratory exchange ratio (RER) were determined using an indirect open-circuit calorimeter. Exercise training increased. (V) over dot(O2max) by about 20% when compared with the initial values (45.6 +/- 1.0 ml kg(-1) min(-1)). During gestation, all groups showed a progressive reduction in the resting (V) over dot(O2) values. Dams in the NT+LP group showed lower values of resting (V) over dot(O2) than those in the NT group. The growth rate of pups from low-protein-fed mothers was around 50% lower than that of their respective controls. The T group showed an increase in body weight from the 60th day onwards, while the NT+LP group presented a reduced body weight from weaning onwards. In conclusion, physical training attenuated the impact of the low- protein

"An on-going individual adjustment" : a qualitative study of midwives' experiences counselling pregnant women on physical activity in Sweden

Background: In Sweden, midwives play prominent supportive role in antenatal care by counselling and promoting healthy lifestyles. This study aimed to explore how Swedish midwives experience the counselling of pregnant women on physical activity, specifically focusing on facilitators and barriers during pregnancy. Also, addressing whether the midwives perceive that their own lifestyle and body shape may influence the content of the counselling they provide. Methods: Eight focus group discussions (FGD) were conducted with 41 midwives working in antenatal care clinics in different parts of Sweden between September 2013 and January 2014. Purposive sampling was applied to ensure a variation in age, work experience, and geographical location. The FGD were digitally recorded, transcribed verbatim, and analyzed using manifest and latent content analysis. Results: The main theme- "An on-going individual adjustment" was built on three categories: "Counselling as a challenge"; "Counselling as walking the thin ice" and "Counselling as an opportunity" reflecting the midwives on-going need to adjust their counselling depending on each woman's specific situation. Furthermore, counselling pregnant women on physical activity was experienced as complex and ambiguous, presenting challenges as well as opportunities. When midwives challenged barriers to physical activity, they risked being rejected by the pregnant women. Despite risking rejection, the midwives tried to promote increased physical activity based on their assessment of individual needs of the pregnant woman. Some participants felt that their own lifestyle and body shape might negatively influence the counselling; however, the majority of participants did not agree with this perspective. Conclusions: Counselling on physical activity during pregnancy may be a challenging task for midwives, characterized by on-going adjustments based on a pregnant woman's individual needs. Midwives strive to find individual solutions to encourage physical activity. However, to improve their counselling, midwives may benefit from further training, also organizational and financial barriers need to be addressed. Such efforts might result in improved opportunities to further support pregnant women's motivation for performance of physical activity.

Gerentes de projeto : um estudo sobre a relação entre perfis psicodemográficos, desempenho e progressão profissional

Dada a crescente estruturação das organizações permanentes em organizações temporárias, aqui representadas como projetos, há uma demanda proporcional por profissionais qualificados que atuem como os maestros dessas empreitadas – os gerentes de projetos (GP’s). Esta pesquisa de dissertação de mestrado tem por objetivo estudar como diferentes traços psicodemográficos, à saber: gênero, etnia, orientação sexual e aparência física, impactam na vida e na progressão profissional do GP que os detenha, pela perspectiva deste profissional. Na busca por possíveis respostas para essa questão, percorremos a teoria procurando os subsídios necessários ao GP para exercer satisfatoriamente sua atividade e ascender na carreira. Vimos que as hard skills desses profissionais são desenhadas e enriquecidas por meio das metodologias e boas práticas trazidas pelas diversas associações internacionais de gestão de projetos. Todavia, as ações prescritivas dessas metodologias apenas delineiam os contornos mais amplos das soft skills. Este conjunto de habilidades se mostrou fundamental para o GP em seu trabalho, sendo empiricamente apreendido e enriquecido pela experiência prática. Ademais, a progressão na carreira de GP é percebida frente à crescente complexidade dos projetos à ele subordinados, como também é percebida ao enveredar por caminhos mais estratégicos e menos operacionais. Calçamos a pesquisa sobre a cultura brasileira, usada como arcabouço para entender como tais profissionais exercem suas relações de liderança, comunicação, respeito e colaboração para com seus stakeholders, ou seja, suas soft skills, e orquestram as atividades necessárias para a conclusão satisfatória de um projeto. Sobre tal base, buscamos entender possíveis preconceitos e barreiras impostas às diferentes psicodemografias para, em sequência, observar quais impactos são percebidos pelos GP’s no exercício de suas atividades, bem como na progressão de suas carreiras. Trouxemos do campo entrevistas com vários GP’s de diferentes psicodemografias. A análise do discurso nos emprestou o ferramental para estudar os dados de campo, e abarcar conclusões sustentadas pela base teórica. Como resultado, percebemos que a cultura brasileira ainda apresenta mecanismos de dominação encarnados por um grupo androcêntrico, etnicamente branco e heterossexual, com prescrições e normas sobre a aparência física. Vimos também que as soft skills são influenciadas pela cultura local, principalmente quando são exercidas por minorias rejeitadas pelo grupo dominante. Percebemos a existência de portas e tetos de vidro na vida profissional de um GP que encarne determinados traços psicodemográficos, bem como uma introjeção de tal lógica androcêntrica. Tais profissionais exercem suas funções com um custo maior do que aquele realizado por homens, brancos, heterossexuais e de boa aparência, bem como precisam se mostrar resilientes à tal dominação. As barreiras para o gênero feminino também se erguem quando a GP mulher, mesmo em um contexto de liderança de uma organização temporária, exerce a maternidade.

Human face verification based on multidimensional Polynomial Powers of Sigmoid (PPS)

In this paper, we described how a multidimensional wavelet neural networks based on Polynomial Powers of Sigmoid (PPS) can be constructed, trained and applied in image processing tasks. In this sense, a novel and uniform framework for face verification is presented. The framework is based on a family of PPS wavelets,generated from linear combination of the sigmoid functions, and can be considered appearance based in that features are extracted from the face image. The feature vectors are then subjected to subspace projection of PPS-wavelet. The design of PPS-wavelet neural networks is also discussed, which is seldom reported in the literature. The Stirling Universitys face database were used to generate the results. Our method has achieved 92 % of correct detection and 5 % of false detection rate on the database.

Humanização hospitalar, ambiente físico e relações assistenciais :a percepção de arquitetos especialistas

The creation of the Humanization Program of Hospital Care and the increasing number of academic works and journal articles that discuss more humane practices in the health care services express the emphasis given to the theme in Brazil. In these discussions, however, it is not usual to find reference to architecture as a relevant factor in the humanization of hospitals, even though it is known that the physical structure of the building may help the recovering of the patients; elements such as gardens, the use of colors and open spaces may soften the impact caused by the hospital routine on patients. Considering the contribution the architectural project may bring to the humanization of hospitals, the aim of this study was to verify how the architects perceive the hospital humanization process. Besides having searched for subsides in informal interviews with health professionals, in visits to hospitals and in related seminars, the study was based on semi-structured interviews with architects of Natal, Rio Grande do Norte, who are specialists in this kind of projects. The content analysis of the interviews showed that physical space and attendance are essential to the humanization process. Those professionals see two humanization tendencies: while private hospitals have the structural physical appearance considered as humanized, public hospitals emphasize the humanization in attendance, fact that illustrates the contradictions in Brazilian health system. The interviewees consider the post-occupancy evaluation of the building as a learning exercise that contributes to new projects, but surprisingly they do not mention the patients opinion as part of it. Two annoying facts have emerged from the interviews, as also seen in preliminary stages of the study: rare are the works that focus on the person-environment relationship, and the definition of humanized hospital environments is still broad and inaccurate. This suggests the need of new studies in order to better understand how the two factors shown in this study attendance and physical space interact towards a true hospital humanization

Trend- und Natursport als System

Zusammenfassung: Freizeitaktivitäten wie Mountainbiking, Sportklettern, Drachen- und Gleitschirmfliegen oder Windsur-fen sind relativ neue Erscheinungen der letzten fünfzehn bis fünfundzwanzig Jahre. Ihre Entwicklung und Ausdifferenzierung beschränkt sich vor allem auf Gesellschaften westlich-industrieller Prägung, deren Grundlage ein funktional differenziertes Gesellschaftssystem ist. Mit Hilfe des Beobachtungsin-strumentes der neueren soziologischen Systemtheorie wird zunächst das Aufkommen und die immer fortschreitende Ausdifferenzierung von Trend- und Natursportarten analysiert und gedeutet. Es zeigt sich, daß diese neuen Freizeitaktivitäten über den Zugriff auf die eigene Körperlichkeit in hohem Ma-ße zur Identitätsfindung der Individuen solcher Gesellschaftssysteme beitragen.Aus geographischer Sicht stellt sich die Frage nach der Bedeutung dieser Entwicklung für die Land-schaft. Dabei wird Landschaft explizit nicht als etwas verstanden, daß 'an sich' existiert, sondern als etwas, das 'erlebt' oder 'begriffen', also immer wieder aufs Neue im Auge des Betrachters konstru-iert wird. Für die Sporttreibenden von Trend- und Natursportarten ist der Blick auf die Welt durch ihre Sportart strukturiert. Jedenfalls immer dann, wenn es darum geht, eine Sportstätte für ihre jeweilige Sportausübung auszuwählen. Die Naturlandschaft (oder auch Kulturlandschaft) wird damit zur 'Sportlandschaft'. Der Begriff der 'Landschaft' erscheint dann im Sinne Werlens 'alltäglichen Geo-graphie-Machens' als eine permanent neu zu erstellende und damit sich auch ständig verändernde Perspektive auf die Objektwelt. So kann sich im Auge der Sporttreibenden von Trend- und Natur-sportarten jedes Objekt und jede Landschaft, wenn man so will: die Welt, als ein einziger großer Sportplatz darstellen.Wenn also alles potentiell eine Sportstätte sein kann, stellt sich die Frage, wie es zur Herausbildung sogenannter Top Spots kommt, also zu jenen Sportstätten, die innerhalb der jeweiligen Sportart von herausragender Bedeutung sind - sozusagen die oberste Sprosse der Karriereleiter erklommen haben - und an der jeder gewesen sein muß, der innerhalb der sportartspezifischen Szene etwas gelten will. Dieser Frage wird anhand eines Fallbeispiels nachgegangen. Als Grundlage wurde ein Untersu-chungsgebiet gewählt, das sich bereits in einem fortgeschrittenen Stadium der Entwicklung zu einem Top Spot befindet - eine Landschaft also, die bereits eine 'Karriere als Sportlandschaft' aufzuweisen hat. Die peripher gelegene US-amerikanische Kleinstadt Moab in Südost-Utah (ca. 5.000 Einwohner) hat sich seit Anfang der 1990er Jahre zu einem internationalen Szene-Treffpunkt für Mountainbiking entwickelt. Zu dem wichtigsten Mountainbike-Trail (dem Slickrock Bike Trail) kommen pro Jahr al-lein mehr als 200.000 Mountainbike-TouristInnen. Neben dem Mountainbiking spielt River Rafting eine bedeutende Rolle im Tourismus und es hat sich dort in den letzten Jahren außerdem eine kleine Sportkletter-Szene etabliert, die in den nächsten Jahren sicherlich noch an Bedeutung zunehmen wird.

Systematic counselling by general practitioners for promoting physical activity in elderly patients: a feasibility study

RESEARCH QUESTIONS: To investigate how the daily physical activities of elderly patients can be enhanced by systematic counselling conducted by general practitioners (GPs). METHODS: In this feasibility study with pre-post design, 29 people (14 females, mean age 72.2 years, SD = 6.1) were enrolled during routine visits by two general practitioners. A baseline assessment of current physical activity based on the stages according to the Transtheoretical Model was followed by a counselling session. The target behaviour was defined by performance of 30 minutes of daily moderate-intensity activities that increase the breathing rate, on five days per week. At the 2-month follow-up, subjects were assessed for improvement in stage of physical activity since baseline. After the end of the intervention, participating GPs and patients were asked questions focusing on the feasibility, acceptance and usefulness of counselling. RESULTS: Interview results showed that the two GPs considered the counselling protocol easy to handle and useful for promoting physical activity. Counselling sessions were especially encouraging for the not sufficiently active people. Most of them would like to have additional counselling session. At baseline, 9 of 29 people were sufficiently active. After 2 months, this proportion was 21 of 29. The mean of the number of minutes of physical activity during the previous 4 weeks increased from 247 to 436 minutes (weekly). CONCLUSIONS: The programme was judged positively by the general practitioners and the participating elderly patients. Systematic counselling by general practitioners led to an increase in the physical activity behaviour. Therefore, a more rigorous randomised controlled trial with adequate followup is recommended.
