    Background Chiropractors are frequent providers of care for patients with lower back pain. Biopsychosocial approaches to managing patients are regarded as best practice and are gaining wider acceptance. Recent evidence suggests that practitioners' attitudes and beliefs may also have an important effect on patients' recovery from back pain. Past studies have pooled manual therapists from differing professions. Dissonant findings have been hypothesised as being a result of the chiropractic subpopulation within multi-practitioner participant pools who are hypothesised to focus on biomedical aspects of treatment and minimize biopsychosocial dimensions. The aim of this study is to determine whether a study population of only chiropractors would demonstrate similar attitudes and beliefs to other manual therapists' biopsychosocial or biomedical approach to the management of their patients. Methods A survey of chiropractors in Victoria Australia in September 2010 was undertaken utilising the Pain Attitude and Belief Scale (PABS.PT), a tool which has been developed to determine the orientation (biopsychosocial or biomedical approach) of practitioners to the management of people with low back pain. The survey also obtained demographic data from respondents to determine whether variables such as education, gender or practice related factors influenced their orientation. Results The overall response rate was 29% (n = 218). The majority of the sample was male (68%), with a mean age of 44 years. The 6 point Likert scale scores were 34.5 (6.3) for the biomedical factor scale and 31.4 (4.1) for the biopsychosocial scale. Internal consistency of the psychosocial subscale was poor. None of the demographic variables were found to influence the biomedical or psychosocial scales. Conclusions Chiropractors in the state of Victoria were found to have similar biomedical and psychosocial orientations in their attitudes and beliefs when compared to other manual therapists' levels of previous studies from differing cultural and educational backgrounds. This study was unable to replicate any of the relationships from past studies with any of the demographic variables. The psychosocial scale internal consistency may be a significant factor in this non-finding. Future research should address the identification of more robust items of the biopsychosocial attitudes of Victorian chiropractors toward treating lower back pain

    Objectives: The aim of this report is to describe the demographic characteristics including the age profile, gender differences, income and perceptions of supply and demand of the chiropractic profession in Australia. This workforce study (WFS) was divided into three components, Australian Chiropractors (Stage 1), their patients (Stage 2), and members of the general public (Stage 3). Methods: A web-based, 64-item, cross-sectional survey questionnaire was issued to registered chiropractors (CAA and non-CAA members) throughout Australia in 2010. At the time of the survey there were 3,892 registered chiropractors. Survey invitations were sent to those who were registered chiropractors, and had provided email addresses (n=1,917). Results: Demographic Characteristics: There is evidence to suggest that the profession may be becoming increasingly female over time. Income exclusively from chiropractic care included 27.9% who reported an annual pre-tax net income of 115,000orlessand32.3115,000 or less and 32.3% earned more than 115,000. Of the latter group, 12% indicated that they were earning more than $215,000. Income was not related to the hours worked per week particularly for males. Supply and Demand: When considering their home state and their local region, more chiropractors thought that there was undersupply in their state, but an adequate supply in their local region. A large proportion (40%) of the sample felt that universities in Australia were graduating the correct number of chiropractors per year, and 32% reported that too many were being produced in Australia. Very few reported that the Universities were not graduating enough chiropractors. Conclusion: This paper reflects some of the findings from Stage 1 of the three stage Workforce study, showing a profession heading towards a more even gender balance and characterised by a higher than average annual income. Future research should include the impact on supply and demand of the possibility of an increasingly female profession. In addition to this, although there is a perception that there is under-utilisation of chiropractic services in inland, rural and remote areas, the extent of which should be further explored. Information from this study will assist with strategic decision making and planning. A strategic framework for the profession should not only consider the findings from this study but also explore other factors that may have an impact on supply and demand, for example general trends in health and aging from local and national government reports

    Chiropractic in Australia: A survey of the general public

    Background: An increase in the use of complementary and alternative medicine was identified in several countries including Australia. There is a need to assess the current position of chiropractic within the Australian health system. Objectives: To estimate the lifetime prevalence of the use of chiropractic in Australia; to investigate the perceptions and attitudes of Australian general public about: their health status, the chiropractic profession, chiropractic and health services in general. Methods: A survey was carried out in which a novel 21-item questionnaire was utilised. To obtain a sample whose opinions would be representative of the Australian general population with a 95% level of significance and 4% margin of error, 600 respondents were required. Descriptive statistics, the chi-squared test and logistic regression were used to present and analyse the data. Results: 757 respondents completed the survey. A high prevalence of pain and discomfort relating to the musculoskeletal system were found, particularly in the lower back (71.1 % of the respondents) and neck (55.6%). The first contact with respect to therapy for the greatest proportion of respondents was general medicine (35.5%), followed by chiropractic (16%), physiotherapy (13.8%) and massage (10.2%). Physiotherapy was rated highest in its ability to relieve the symptoms (18%) followed by chiropractic (15.9%), massage (15.5%) and medicine (14%). In our sample 302 (39.9%) participants used chiropractic before and 75.9% of these consumers were satisfied or highly satisfied with the services provided. No significant differences in income, age and gender were found with regards to those individuals who reported a previous use of chiropractic services. The main reasons for not using chiropractic were: that there was no perceived need for a chiropractic intervention, associated cost, lack of information about chiropractic, lack of referral, being attended by another health professional, and concern about the safety and efficacy of the treatment. Most of the respondents considered that attending to general health and well-being was more important than simply alleviating symptoms and their personal philosophy was a major determinant when it came to the choice of health services. Conclusions: This study suggests that chiropractic is a thriving profession in Australia. It would appear that there is a need for chiropractic services in Australia, particularly in attending to the highly prevalent realm of musculoskeletal disorders. A considerable number of Australians already utilise chiropractic services. Encouragingly, the vast majority of these consumers are satisfied with the service provided. Chiropractic could play an even greater role within the Australian health if better integrated with the mainstream and allied medicine. A more active approach should be taken by chiropractic practitioners and institutions to improve the general public's knowledge about chiropractic

    Approximate Deadline-Scheduling with Precedence Constraints

    We consider the classic problem of scheduling a set of n jobs non-preemptively on a single machine. Each job j has non-negative processing time, weight, and deadline, and a feasible schedule needs to be consistent with chain-like precedence constraints. The goal is to compute a feasible schedule that minimizes the sum of penalties of late jobs. Lenstra and Rinnoy Kan [Annals of Disc. Math., 1977] in their seminal work introduced this problem and showed that it is strongly NP-hard, even when all processing times and weights are 1. We study the approximability of the problem and our main result is an O(log k)-approximation algorithm for instances with k distinct job deadlines

    Quantum properties of transverse pattern formation in second-harmonic generation

    We investigate the spatial quantum noise properties of the one dimensional transverse pattern formation instability in intra-cavity second-harmonic generation. The Q representation of a quasi-probability distribution is implemented in terms of nonlinear stochastic Langevin equations. We study these equations through extensive numerical simulations and analytically in the linearized limit. Our study, made below and above the threshold of pattern formation, is guided by a microscopic scheme of photon interaction underlying pattern formation in second-harmonic generation. Close to the threshold for pattern formation, beams with opposite direction of the off-axis critical wave numbers are shown to be highly correlated. This is observed for the fundamental field, for the second harmonic field and also for the cross-correlation between the two fields. Nonlinear correlations involving the homogeneous transverse wave number, which are not identified in a linearized analysis, are also described. The intensity differences between opposite points of the far fields are shown to exhibit sub-Poissonian statistics, revealing the quantum nature of the correlations. We observe twin beam correlations in both the fundamental and second-harmonic fields, and also nonclassical correlations between them.Comment: 18 pages, 17 figures, submitted to Phys. Rev.

    Management recommendations for the northern goshawk in the southwestern United States

    Get PDF
    Present forest conditions--loss of a herbaceous and shrubby understory, reductions in the amount of older forests, and increased areas of dense tree regeneration--reflect the extent of human influence on these forests. These changes may also be affecting goshawk populations. Information on goshawk nesting habitat and foraging behavior, and the food and habitats of selected goshawk prey, was therefore synthesized to develop a set of management objectives, desired forest conditions, and management recommendations. Key objectives of the guidelines are to provide (1) nesting, post-fledging, and foraging areas for goshawks, and (2) habitat to support abundant populations of 14 primary goshawk prey. Thinning trees in the understory, creating small openings in the forest, and prescribed fires should help produce and maintain the desired forest conditions. Other habitat elements critical for maintaining both goshawk and prey populations include abundant snags and large downed logs, woody debris, interspersion of different tree sizes across the landscape, and the majority of a goshawk's home range in older-aged forests. These guidelines should also benefit forest health, soil productivity, and the habitats of other old-growth dependent plants and animals

    The Listening Network and Cochlear Implant Benefits in Hearing-Impaired Adults

    Older adults with mild or no hearing loss make more errors and expend more effort listening to speech. Cochlear implants (CI) restore hearing to deaf patients but with limited fidelity. We hypothesized that patient-reported hearing and health-related quality of life in CI patients may similarly vary according to age. Speech Spatial Qualities (SSQ) of hearing scale and Health Utilities Index Mark III (HUI) questionnaires were administered to 543 unilaterally implanted adults across Europe, South Africa, and South America. Data were acquired before surgery and at 1, 2, and 3 years post-surgery. Data were analyzed using linear mixed models with visit, age group (18–34, 35–44, 45–54, 55–64, and 65+), and side of implant as main factors and adjusted for other covariates. Tinnitus and dizziness prevalence did not vary with age, but older groups had more preoperative hearing. Preoperatively and postoperatively, SSQ scores were significantly higher (¿0.75–0.82) for those aged <45 compared with those 55+. However, gains in SSQ scores were equivalent across age groups, although postoperative SSQ scores were higher in right-ear implanted subjects. All age groups benefited equally in terms of HUI gain (0.18), with no decrease in scores with age. Overall, younger adults appeared to cope better with a degraded hearing before and after CI, leading to better subjective hearing performance.

    Search for the Rare Decay KL --> pi0 ee

    The KTeV/E799 experiment at Fermilab has searched for the rare kaon decay KL--> pi0ee. This mode is expected to have a significant CP violating component. The measurement of its branching ratio could support the Standard Model or could indicate the existence of new physics. This letter reports new results from the 1999-2000 data set. One event is observed with an expected background at 0.99 +/- 0.35 events. We set a limit on the branching ratio of 3.5 x 10^(-10) at the 90% confidence level. Combining the results with the dataset taken in 1997 yields the final KTeV result: BR(KL --> pi0 ee) < 2.8 x 10^(-10) at 90% CL.Comment: 4 pages, three figure

    An ideal journey: Making bus travel desirable

    Get PDF
    © 2016 Informa UK Limited, trading as Taylor & Francis Group. This paper explores the ways in which people use their travel-time on local buses, and explains how this knowledge can assist with efforts in many ‘auto-centric’ societies to make bus travel more attractive and encourage a shift away from excessive private car use. Framing the discussion around the concept of an ‘ideal bus journey’, this paper examines whether travel-time activities on-board the bus give subjective value to the journey experience. Particular attention is given to emergent mobile Information and Communications Technologies, which are rapidly reconfiguring the ways in which we can inhabit and use mobile spaces such as the bus. This paper reports a novel mixed-methodology, creating a synthesised analysis of online discussions, focus groups, and a large-scale questionnaire survey of 840 bus users in Bristol, UK. The findings demonstrate that the bus is a very active space, with high levels of travel-time activity. The most popular activities on the bus are those related to relaxation and personal benefit, such as reading, listening to music, and browsing the internet. It is the passengers themselves that are largely in control of their in-vehicle experience, being able to craft a range of different positive journey experiences through travel-time activity. However, negative experiences are very common, and there is a need to challenge unfavourable public perception and media representations of bus travel to create a more positive cultural construction of the bus which would allow for the concept of an ‘ideal journey’ to be more easily realised. Passengers are the main creators of their travel-time experience, however there is much that can be done by bus operators to facilitate different types of activity and encourage a desirable public space. The overarching message is that there is a distinct opportunity to unlock travel-time activity as a ‘Unique Selling Point’ of the bus. Creating a perception of the bus journey as a desirable piece of time will allow local bus services to compete with the car on their own terms, and assist with international efforts to encourage people out of their cars and onto public transport for some trips

    Primordialists and Constructionists: a typology of theories of religion

    Get PDF
    This article adopts categories from nationalism theory to classify theories of religion. Primordialist explanations are grounded in evolutionary psychology and emphasize the innate human demand for religion. Primordialists predict that religion does not decline in the modern era but will endure in perpetuity. Constructionist theories argue that religious demand is a human construct. Modernity initially energizes religion, but subsequently undermines it. Unpacking these ideal types is necessary in order to describe actual theorists of religion. Three distinctions within primordialism and constructionism are relevant. Namely those distinguishing: a) materialist from symbolist forms of constructionism; b) theories of origins from those pertaining to the reproduction of religion; and c) within reproduction, between theories of religious persistence and secularization. This typology helps to make sense of theories of religion by classifying them on the basis of their causal mechanisms, chronology and effects. In so doing, it opens up new sightlines for theory and research
