The recent energy demands affected by the dilution of conventional energy resources and the growing awareness of environmental considerations, had positioned the research of renewable energy conversion methods in general and of thermoelectric direct conversion of thermal into electrical energies in particular, in the forefront of the currently active applicative sciences. IV-VI thermoelectric compounds (e.g. GeTe, PbTe and SnTe) and their alloys comprise some of the most efficient thermoelectric compositions ever reported. Yet a proper utilization of such materials in practical thermoelectric devices, still requires an overcoming the so-called technological “valley of death”, including among others, transport properties' degradation, duemore » to sublimation of volatile Te rich species, while being subjected to elevated temperatures for long periods of time. In an attempt to establish practical operation criteria for extending the operation periods of such thermoelectric converters, it is currently shown based on thermal gravimetric and metallurgical considerations that such harmful sublimation can be practically bridged over by limiting the maximal operating temperatures to the 410–430 °C range for GeTe rich alloys and to 510–530 °C for PbTe and SnTe rich alloys, depending of the thermoelectric leg's diameter. - Graphical abstract: Evaporation rate in the GeTe and PbTe system showing the measured evaporation rates and the maximal operating temperatures for different compositions.

Implementing the patient-centered medical home model for chronic disease care in small medical practices: practice group characteristics and physician understanding.

PubMed

Baxter, Louisa; Nash, David B

2013-01-01

Strengthening primary care may improve health outcomes and restrain spending. The patient-centered medical home (PCMH) model is endorsed as a tool to achieve this. Early evaluations in large group practices demonstrate improvements in some health outcomes. Evidence is lacking from small medical practices that deliver the majority of primary health care. This was a national survey of 200 physicians that explored perceptions of PCMH. There was considerable interest in adoption of the model; however, providing PCMH care was seen as an extension of traditional roles that requires additional reimbursement. No differentiation was made among a variety of payment models to do this. All joint principle components of the model were identified as important: extending access and information technology were the most contentious. There was consensus that PCMH might improve the quality of primary care; however, tension between wider societal benefits and rising costs for individual practices was a challenge to implementation.

Generalized causal mediation and path analysis: Extensions and practical considerations.

Causal mediation analysis seeks to decompose the effect of a treatment or exposure among multiple possible paths and provide casually interpretable path-specific effect estimates. Recent advances have extended causal mediation analysis to situations with a sequence of mediators or multiple contemporaneous mediators. However, available methods still have limitations, and computational and other challenges remain. The present paper provides an extended causal mediation and path analysis methodology. The new method, implemented in the new R package, gmediation (described in a companion paper), accommodates both a sequence (two stages) of mediators and multiple mediators at each stage, and allows for multiple types of outcomes following generalized linear models. The methodology can also handle unsaturated models and clustered data. Addressing other practical issues, we provide new guidelines for the choice of a decomposition, and for the choice of a reference group multiplier for the reduction of Monte Carlo error in mediation formula computations. The new method is applied to data from a cohort study to illuminate the contribution of alternative biological and behavioral paths in the effect of socioeconomic status on dental caries in adolescence.

Cross-border mergers and acquisitions (M&A) require considerable intercultural openness on the part of the managers involved. A recent wave of takeovers by private equity investors and foreign investors from emerging economies has challenged German executives. In cases of friendly takeovers, as described in this study, managers at first appear to extend a cosmopolitan welcome to the new owners. However, further analysis of structural hermeneutics reveals latent normative professional ethics of managers which lead to practices of distancing, in particular from young investors from China, India, and Russia.

Large amounts of water applied as urban irrigation can often be reduced substantially without compromising esthetics. Thus, encouraging the adoption of water-saving technologies and practices is critical to preserving water resources, yet difficult to achieve. The research problem addressed in this study is the lack of characterization of residents who use urban irrigation, which hinders the design of effective behavior change programs. This study examined audience segmentation as an approach to encouraging change using current residential landscape practices. K-means cluster analysis identified three meaningful subgroups among residential landscape irrigation users ( N = 1,063): the water considerate majority ( n = 479, 45 %), water savvy conservationists ( n = 378, 36 %), and unconcerned water users ( n = 201, 19 %). An important finding was that normative beliefs, attitudes, and perceived behavioral control characteristics of the subgroups were significantly different with large and medium practical effect sizes. Future water conservation behaviors and perceived importance of water resources were also significantly different among subgroups. The water considerate majority demonstrated capacity to conserve, placed high value on water, and were likely to engage in behavior changes. This article contributes to the literature on individuals who use residential landscape irrigation, an important target audience with potential to conserve water through sustainable irrigation practices and technologies. Findings confirm applicability of the capacity to conserve water to audience segmentation and extend this concept by incorporating perceived value of water resources and likelihood of conservation. The results suggest practical application to promoting residential landscape water conservation behaviors based on important audience characteristics.

If We Build It, They Will Come: Exploring Policy and Practice Implications of Public Support for Couple and Relationship Education for Lower Income and Relationally Distressed Couples.

Bradford, Angela B; Hawkins, Alan J; Acker, Jennifer

2015-12-01

Over the past decade, public funding for Couple and Relationship Education programs has expanded. As program administrators have been able to extend their reach to low-income individuals and couples using this support, it has become apparent that greater numbers of relationally distressed couples are attending classes than previously anticipated. Because psychoeducational programs for couples have traditionally served less distressed couples, this dynamic highlights the need to examine the policy and practice implications of more distressed couples accessing these services. This paper reviews some of the most immediate issues, including screening for domestic violence and couple needs, pedagogical considerations, and the potential integration of therapy and education services. We also make suggestions for future research that can inform policy and practice efforts. © 2015 Family Process Institute.

In his commentary on our previously published article "Readability of Self-Report Measures of Depression and Anxiety," J. Schinka (2012) argued for the importance of considering readability of patient materials and highlighted limitations of existing methodologies for this assessment. Schinka's commentary articulately described the weaknesses of readability assessment and emphasized the importance of the development of improved strategies for assessing readability to maximize the validity of self-report measures in applied settings. In our reply, we support and extend Schinka's argument, highlighting the importance of consideration of the range of factors (e.g., use of reverse-scored items) that may increase respondent difficulty with comprehension. Consideration of the readability of self-report symptom measures is critical to the validity of these measures in both clinical practice and research settings.

An extended fatty liver index to predict non-alcoholic fatty liver disease.

In clinical practice, there is a strong interest in non-invasive markers of non-alcoholic fatty liver disease (NAFLD). Our hypothesis was that the fold-change in plasma triglycerides (TG) during a 2-h oral glucose tolerance test (fold-change TG OGTT ) in concert with blood glucose and lipid parameters, and the rs738409 C>G single nucleotide polymorphism (SNP) in PNPLA3 might improve the power of the widely used fatty liver index (FLI) to predict NAFLD. The liver fat content of 330 subjects was quantified by 1 H-magnetic resonance spectroscopy. Blood parameters were measured during fasting and after a 2-h OGTT. A subgroup of 213 subjects underwent these measurements before and after 9 months of a lifestyle intervention. The fold-change TG OGTT was closely associated with liver fat content (r=0.51, P<0.0001), but had less power to predict NAFLD (AUROC=0.75) than the FLI (AUROC=0.79). Not only was the fold-change TG OGTT independently associated with liver fat content and NAFLD, but so also were the 2-h blood glucose level and rs738409 C>G SNP in PNPLA3. In fact, a novel index (extended FLI) generated from these and the usual FLI parameters considerably increased its power to predict NAFLD (AUROC=0.79-0.86). The extended FLI also increased the power to predict changes in liver fat content with a lifestyle intervention (n=213; standardized beta coefficient: 0.23-0.29). This study has provided novel data confirming that the OGTT-derived fold-change TG OGTT and 2-h glucose level, together with the rs738409 C>G SNP in PNPLA3, allow calculation of an extended FLI that considerably improves its power to predict NAFLD.

The identification of feasible and practical applications of space teleoperator technology for the problems of the handicapped were studied. A teleoperator system is defined by NASA as a remotely controlled, cybernetic, man-machine system designed to extend and augment man's sensory, manipulative, and locomotive capabilities. Based on a consideration of teleoperator systems, the scope of the study was limited to an investigation of these handicapped persons limited in sensory, manipulative, and locomotive capabilities. If the technology being developed for teleoperators has any direct application, it must be in these functional areas. Feasible and practical applications of teleoperator technology for the problems of the handicapped are described, and design criteria are presented with each application. A development plan is established to bring the application to the point of use.

Promotion of nutrition care by Australian fitness businesses: a website analysis.

2016-11-01

To investigate the intention of fitness businesses to promote the provision of nutrition care from personal trainers. Cross-sectional evaluation of webpage content. Fitness businesses within two Australian federal electorates were identified using the Fitness Australia list of registered fitness businesses. Inductive content analysis of these fitness business websites and associated social media sites was undertaken to compare website content to the Fitness Australia Position Statement outlining the Roles and Responsibilities of Registered Fitness Professionals. Fitness businesses were classified as 'within scope of practice' if they referred to national nutrition guidelines or dietetic services. 'At risk of being beyond scope' included websites which did not include enough information to definitively state within or beyond scope. Fitness businesses were classified as 'definitely beyond scope of practice' if they advertised nutrition care which clearly extended beyond translation of the national dietary guidelines. Of the businesses reviewed, 15% were within scope despite none referring to a dietitian; 34% were at risk of being beyond scope; and 51% were beyond scope as they advertised nutrition care such as personalized diets without indicating dietetic input. A considerable portion of fitness businesses reviewed advertised their personal trainers as able to provide nutrition care outside the recommended scope of practice. Strategies that help fitness businesses and personal trainers to support clients to have healthy dietary behaviours without extending outside the scope of practice are warranted.

This article builds on assertions in Richardson’s (2012, this issue) Major Contribution on counseling for work and relationship. In this reaction, I expand on the relevance and potential of the counseling for work and relationship perspective to enrich the field of counseling psychology. My comments focus on three considerations to further extend the cultural relevance of Richardson’s work and relationship perspective: (1) broadening sources of dignity, (2) centering knowledge of marginalized communities, and (3) promoting psychologists’ critical consciousness. Richardson’s perspective holds great promise for being a guiding heuristic to inform counseling psychology research, theory, and practice. PMID:22563131

Optimizing Quality of Life in Patients with Hormone Receptor-Positive Metastatic Breast Cancer: Treatment Options and Considerations.

PubMed

Chalasani, Pavani

2017-01-01

The treatment landscape for hormone receptor-positive metastatic breast cancer continues to evolve as the molecular mechanisms of this heterogeneous disease are better understood and targeted treatment strategies are developed. Patients are now living for extended periods of time with this disease as they progress through sequential lines of treatment. With a rapidly expanding therapeutic armamentarium, the prevalence of metastatic breast cancer patients with prolonged survival is expected to increase, as is the duration of survival. Practice guidelines recommend endocrine therapy alone as first-line therapy for the majority of patients with metastatic hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer. The approval of new agents and expanded combination options has extended their use beyond first line, but endocrine therapy is not used as widely in clinical practice as recommended. As all treatments are palliative, even as survival is prolonged, optimizing and maintaining patient quality of life is crucial. This article surveys data relevant to the use of endocrine therapy in the setting of hormone receptor-positive metastatic breast cancer, including key clinical evidence regarding approved therapies and the impact of these therapies on patient quality of life. © 2017 S.

For the purpose of investigating lining concrete durability, this study derives a modified chloride diffusion model for concrete based on the odd continuation of boundary conditions and Fourier transform. In order to achieve this, the linear stress distribution on a sectional structure is considered, detailed procedures and methods are presented for model verification and parametric analysis. Simulation results show that the chloride diffusion model can reflect the effects of linear stress distribution of the sectional structure on the chloride diffusivity with reliable accuracy. Along with the natural environmental characteristics of practical engineering structures, reference value ranges of model parameters are provided. Furthermore, a chloride diffusion model is extended for the consideration of multi-factor coupling of linear stress distribution, chloride concentration and diffusion time. Comparison between model simulation and typical current research results shows that the presented model can produce better considerations with a greater universality.

Auto-driven Photo Elicitation Interviews in Research with Children: Ethical and Practical Considerations.

Children can sometimes find it difficult to articulate their experiences if they have to rely solely on words. Giving children the opportunity to use arts-based research approaches can support their participation in research and create a bridge that enables them to express their perspectives and feelings. This paper focuses on the ethical and practical considerations when using photo elicitation interviews (PEI) in research with children. The discussion and examples provided are drawn from an international study that used auto-driven PEI, where photographs are taken by children themselves, to explore children's experiences of living with a chronic condition and the impact condition management may have on their everyday lives. In this paper we critically explore the issues arising from our use of PEI including children's participation and engagement, balancing power and control, and keeping children safe. The main areas of focus for the paper are how PEI provided a means of shifting control; how setting photographic boundaries influenced our PEI study with children; and how we addressed risks associated with the method. Our experience shows that PEI is an engaging and valuable research method, providing a powerful medium for obtaining rich data with children. However, PEI is challenging and it requires researchers to conscientiously address ethical and practical aspects that extend beyond those inherent to standard (words-alone) interviews.

Tailoring treatment of haemophilia B: accounting for the distribution and clearance of standard and extended half-life FIX concentrates.

The prophylactic administration of factor IX (FIX) is considered the most effective treatment for haemophilia B. The inter-individual variability and complexity of the pharmacokinetics (PK) of FIX, and the rarity of the disease have hampered identification of an optimal treatment regimens. The recent introduction of extended half-life recombinant FIX molecules (EHL-rFIX), has prompted a thorough reassessment of the clinical efficacy, PK and pharmacodynamics of plasma-derived and recombinant FIX. First, using longer sampling times and multi-compartmental PK models has led to more precise (and favourable) PK for FIX than was appreciated in the past. Second, investigating the distribution of FIX in the body beyond the vascular space (which is implied by its complex kinetics) has opened a new research field on the role for extravascular FIX. Third, measuring plasma levels of EHL-rFIX has shown that different aPTT reagents have different accuracy in measuring different FIX molecules. How will this new knowledge reflect on clinical practice? Clinical decision making in haemophilia B requires some caution and expertise. First, comparisons between different FIX molecules must be assessed taking into consideration the comparability of the populations studied and the PK models used. Second, individual PK estimates must rely on multi-compartmental models, and would benefit from adopting a population PK approach. Optimal sampling times need to be adapted to the prolonged half-life of the new EHL FIX products. Finally, costs considerations may apply, which is beyond the scope of this manuscript but might be deeply connected with the PK considerations discussed in this communication.

Attitudes of dentists and dental hygienists towards extended scope and independent dental hygiene practice are described in several studies, but the results are heterogenous. The purpose of this systematic review was to compare the attitudes of dentists and dental hygienists towards extended scope and independent dental hygiene practice. PubMed, AMED and CINAHL were screened by two independent assessors to identify relevant studies. Only quantitative studies that reported the percentages of dentists' and dental hygienists' attitude towards extended scope and independent dental hygiene practice were included. The random-effects model was used to synthesise possible heterogenous influences. Meta proportions with regard to a positive attitude towards extended scope of practice are 0.54 for dentists and 0.81 for dental hygienists. Meta proportions of a positive attitude towards independent practice are 0.14 for dentists and 0.59 for dental hygienists. A meta analysis with regard to negative attitudes could only be performed on extended scope of practice and did not reveal a difference between the two professions. We obtained homogeneous outcomes of the studies included regarding negative attitudes of dentists . A minority of dentists hold negative attitudes towards extended scope of dental hygiene practice. Study outcomes regarding negative attitudes of dental hygienists were heterogeneous. Positive attitudes are present among a majority of dentists and dental hygienists with regard to extended scope of dental hygiene practice, while for independent dental hygiene practice this holds for a minority of dentists and a majority of dental hygienists. © 2016 FDI World Dental Federation.

We investigate the regularization-scheme dependent treatment of γ5 in the framework of dimensional regularization, mainly focusing on the four-dimensional helicity scheme (fdh). Evaluating distinctive examples, we find that for one-loop calculations, the recently proposed four-dimensional formulation (fdf) of the fdh scheme constitutes a viable and efficient alternative compared to more traditional approaches. In addition, we extend the considerations to the two-loop level and compute the pseudoscalar form factors of quarks and gluons in fdh. We provide the necessary operator renormalization and discuss at a practical level how the complexity of intermediate calculational steps can be reduced in an efficient way.

Each expandable space frame comprises a plurality of hinge joint assemblies having arms that extend outwardly in predetermined symmetrically related directions from a central or vertex point. The outer ends of the arms form one part of a hinge point. The outer expandable space frame also comprises a plurality of struts. The outer ends of the struts from the other part of the hinged joint. The struts interconnect the plurality of hinge point in sychronism, the spaceframes can be expanded or collapsed. Three-dimensional as well as two-dimensional spaceframes of this general nature are described.

Estimating Coherence Measures from Limited Experimental Data Available

2018-04-01

Quantifying coherence has received increasing attention, and considerable work has been directed towards finding coherence measures. While various coherence measures have been proposed in theory, an important issue following is how to estimate these coherence measures in experiments. This is a challenging task, since the state of a system is often unknown in practical applications and the accessible measurements in a real experiment are typically limited. In this Letter, we put forward an approach to estimate coherence measures of an unknown state from any limited experimental data available. Our approach is not only applicable to coherence measures but can be extended to other resource measures.

Time utilization, productivity and costs of solo and extended duty auxiliary dental practice.

Tan, H H; van Gemert, H G

1977-07-01

A study was conducted to compare the time utilization of the dentist, and productivity and costs for solo (one dentist, one chairside assistant and one treatment room) and extended duty settings (one dentist, two extended duty dental hygienists, one chairside assistant and two treatment rooms). Only amalgam and composite restorations done in a general group practice were included. In the extended duty setting the dentist spent more time in managerial activities and less time in treatment than in the solo setting. Nevertheless, the dentist in the extended duty setting produced 53% more restorations as compared with solo practice. The cost ratio of solo to extended duty practice was computed to 1:1.52. From the point of view of microeconomics, the extended duty setting was found no worse than the solo setting.

Deriving consensus on the characteristics of advanced practice nursing: meta-summary of more than 2 decades of research.

PubMed

Hutchinson, Marie; East, Leah; Stasa, Helen; Jackson, Debra

2014-01-01

Over recent decades, there has been considerable research and debate about essential features of advanced nursing practice and differences among various categories of advanced practice nurses. This study aimed to derive an integrative description of the defining characteristics of advanced practice nursing through a meta-summary of the existing literature. A three-phase approach involved (a) systematic review of the literature to identify the specific activities characterized as advanced practice nursing, (b) qualitative meta-summary of practice characteristics extracted from manuscripts meeting inclusion criteria; and (c) statistical analysis of domains across advanced practice categories and country in which the study was completed. A descriptive framework was distilled using qualitative and quantitative results. Fifty manuscripts met inclusion criteria and were retained for analysis. Seven domains of advanced nursing practice were identified: (a) autonomous or nurse-led extended clinical practice; (b) improving systems of care; (c) developing the practice of others; (d) developing/delivering educational programs/activities; (e) nursing research/scholarship; (f) leadership external to the organization; and (g) administering programs, budgets, and personnel. Domains were similar across categories of advanced nursing practice; the domain of developing/delivering educational programs/activities was more common in Australia than in the United States or United Kingdom. Similarity at the domain level was sufficient to suggest that advanced practice role categories are less distinct than often argued. There is merit in adopting a more integrated and consistent interpretation of advanced practice nursing.

Pharmacological approaches to the management of type 2 diabetes in fasting adults during Ramadan

PubMed Central

AlMaatouq, Mohamed A

2012-01-01

More than 50 million Muslims throughout the world with type 2 diabetes mellitus (T2DM) fast for one lunar month (Ramadan) each year. Health care providers within and outside the Muslim world need to be aware of the nature of these partial days of fasting and their risks (and potential benefits) to people with T2DM, and need to provide Ramadan-adjusted diabetes care. Hypoglycemia during the fasting days represents the greatest health risk for these patients; hence, diabetes-related pharmacotherapy needs to be tailored and adjusted with this risk in mind. With limited trial data available, this review proposes practical modifications to the usual pre-Ramadan antidiabetic regimens that are based on pathophysiological principles, clinical trial evidence (where available), expert opinion, and extended practical experience. Individualization of care is paramount in this regard to take into consideration the patient and societal, cultural, and economic variables. PMID:22654520

Extending Data Worth Analyses to Select Multiple Observations Targeting Multiple Forecasts.

PubMed

Vilhelmsen, Troels N; Ferré, Ty P A

2018-05-01

Hydrological models are often set up to provide specific forecasts of interest. Owing to the inherent uncertainty in data used to derive model structure and used to constrain parameter variations, the model forecasts will be uncertain. Additional data collection is often performed to minimize this forecast uncertainty. Given our common financial restrictions, it is critical that we identify data with maximal information content with respect to forecast of interest. In practice, this often devolves to qualitative decisions based on expert opinion. However, there is no assurance that this will lead to optimal design, especially for complex hydrogeological problems. Specifically, these complexities include considerations of multiple forecasts, shared information among potential observations, information content of existing data, and the assumptions and simplifications underlying model construction. In the present study, we extend previous data worth analyses to include: simultaneous selection of multiple new measurements and consideration of multiple forecasts of interest. We show how the suggested approach can be used to optimize data collection. This can be used in a manner that suggests specific measurement sets or that produces probability maps indicating areas likely to be informative for specific forecasts. Moreover, we provide examples documenting that sequential measurement election approaches often lead to suboptimal designs and that estimates of data covariance should be included when selecting future measurement sets. © 2017, National Ground Water Association.

Safety climate and mindful safety practices in the oil and gas industry.

Dahl, Øyvind; Kongsvik, Trond

2018-02-01

The existence of a positive association between safety climate and the safety behavior of sharp-end workers in high-risk organizations is supported by a considerable body of research. Previous research has primarily analyzed two components of safety behavior, namely safety compliance and safety participation. The present study extends previous research by looking into the relationship between safety climate and another component of safety behavior, namely mindful safety practices. Mindful safety practices are defined as the ability to be aware of critical factors in the environment and to act appropriately when dangers arise. Regression analysis was used to examine whether mindful safety practices are, like compliance and participation, promoted by a positive safety climate, in a questionnaire-based study of 5712 sharp-end workers in the oil and gas industry. The analysis revealed that a positive safety climate promotes mindful safety practices. The regression model accounted for roughly 31% of the variance in mindful safety practices. The most important safety climate factor was safety leadership. The findings clearly demonstrate that mindful safety practices are highly context-dependent, hence, manageable and susceptible to change. In order to improve safety climate in a direction which is favorable for mindful safety practices, the results demonstrate that it is important to give the fundamental features of safety climate high priority and in particular that of safety leadership.

New roles and challenges within the healthcare workforce: a Heideggerian perspective.

PubMed

Wilson, Anthea

2015-01-01

The purpose of this paper is to explore insights based on the phenomenology of Martin Heidegger, on the dynamic relationships between human experience and work roles. Drawing on the findings of a hermeneutic phenomenological study of nurse mentors, the topics of new roles and role challenges are explored, along with a consideration of their relevance to wider issues of workforce redesign. Heidegger's philosophy of Dasein, in particular his concepts of inauthentic and authentic self, provided an interpretational lens. This paper applies these philosophical concepts to challenges associated with a changing workforce. Concepts elaborating human existence as proposed by Heidegger may offer analytic structures for understanding shifts in the lived experience of a changing workplace. In particular, the concepts could help managers to explore the implications of introducing novel work roles or extending roles. The understanding gained can also extend to situations where work practices may need to be challenged. As work roles and skill mix undergo rapid shifts, this paper offers an original way of understanding the experience of work roles.

Components and Quality Measures of DIME (Devitalized Tissue, Infection/Inflammation, Moisture Balance, and Edge Preparation) in Wound Care

Snyder, Robert J.; Fife, Caroline; Moore, Zena

2016-01-01

ABSTRACT OBJECTIVES: To discuss how patient considerations and the initial wound environment can affect wound treatment and summarize the way in which the initial US Wound Registry measures capture aspects of the DIME (Debridement/devitalized tissue, Infection or inflammation, Moisture balance, and wound Edge preparation/wound depth) principles. DISCUSSION: The treatment of chronic wounds often involves extended hospital stays and long-term outpatient follow-up visits with costly advanced therapeutic interventions. As complex care is required for chronic wounds, treatment guidelines such as DIME have evolved to include consideration of patient-centered concerns and etiology, as well as features of wound bed preparation. The US healthcare system is in the midst of transitioning to a quality-based system. However, as wound care is not yet a recognized specialty, it is poorly represented in the current approved quality-based measures. CONCLUSION: This article helps to identify the practice guidelines that are not currently represented by quality metrics. PMID:27089149

In medical education and practice, smartphone apps are increasingly becoming popular. In general practice, apps could play an important future role in supporting medical education and practice. To explore medical students' perceptions regarding the potential of a general practice app for training and subsequent work as a physician. Cross-sectional survey among Leipzig fourth-year medical students who were provided with an app prototype for a mandatory general practice course. Response rate was 99.3% (n = 305/307); 59.0% were female and mean age was 24.5 years. Students certified that the app had a higher potential than textbooks in both education (57.4% vs. 18.0%) and practice (47.1% vs. 22.8%). Students' most desired possible app extensions when anticipating its use for subsequent work as a physician were looking up information for diagnostics, therapy and prediction (85.1%), access to electronic patient files (48.1%), communication and networking (44.3%), organization of medical training (42.9%) and online monitoring of patients (38.1%). Students experienced with medical smartphone apps were more interested in app extensions. Consideration to use the app to support the opening of their own practice was significantly associated with higher interest in accessing electronic patient files, networking with colleagues and telemedicine. Fourth year medical students from Leipzig see a high potential in smartphone apps for education and practice and are interested in further using the technology after undergraduate education.

Dispersion properties of plasma cladded annular optical fiber

One of the considerable problems in a conventional image transferring fiber optic system is the two-fold coupling of propagating hybrid modes. In this paper, using a simple and practical analytical approach based on exact modal vectorial analysis together with Maxwell's equations, we show that applying plasma as a cladding medium of an annular optical fiber can remove this defect of conventional fiber optic automatically without any external instrument as the polarization beam splitter. Moreover, the analysis indicates that the presence of plasma in the proposed optical fiber could extend the possibilities for controlling the propagation property. The proposed structure presents itself as a promising route to advanced optical processing and opens new avenues in applied optics and photonics.

Spacelab experiment definition study on phase transition and critical phenomena in fluids: Interim report on experimental justification

Pure fluids and fluid mixtures near critical points are identified and are related to the progress of several disciplines. Consideration is given to thermodynamic properties, transport properties, and the complex nonlinear phenomena which occur when fluids undergo phase transitions in the critical region. The distinction is made between practical limits which may be extended by advances in technology and intrinsic ones which arise from the modification of fluid properties by the earth's gravitational field. The kinds of experiments near critical points which could best exploit the low gravity environment of an orbiting laboratory are identified. These include studies of the index of refraction, constant volume specific heat, and phase separation.

An increase in the number of veterinarians, while at the same time the number of animals has remained constant, has resulted in growing competition. By extending the range of products and by enlarging the veterinarians' scope of activities this competition can be decreased. A marketing-orientation will be helpful in this respect. This article indicates in which way marketing concepts can be used in a veterinary practice. The services of the veterinarian will be looked at by means of the Abell approach. This focuses on the functions performed by the services and examines, per function performed, for whom this might be interesting and which alternatives there might be. Next the concept of market segmentation is filled in for a veterinary practice by means of a hypothetical example. The marketing mix (product, place, price, promotion and personnel) is given considerable attention. The last element of marketing in a veterinary practice that is discussed here is the marketing information system. In a next article the question will be answered how marketing-directed the Dutch veterinarian works nowadays. To find this out research has been done; 166 vets were interviewed by telephone for approximately 40 minutes each.

Assisted or Hastened Death: The Healthcare Practitioner’s Dilemma

PubMed Central

MacLeod, Rod D; Wilson, Donna M; Malpas, Phillipa

2012-01-01

Assisting or hastening death is a dilemma with many ethical as well as practical issues facing healthcare practitioners in most countries worldwide now. Various arguments for and against assisted dying have been made over time but the call from the public for the legalisation of euthanasia and assisted suicide has never been stronger. While some studies have documented the reluctance of medical and other healthcare professionals to be involved in the practice of assisted dying or euthanasia, there is still much open debate in the public domain. Those who have the most experience of palliative care are strongest in their opposition to hastening death. This paper explores salient practical and ethical considerations for healthcare practitioners associated with assisting death, including a focus on examining the concepts of autonomy for patients and healthcare practitioners. The role of the healthcare practitioner has clearly and undoubtedly changed over time with advances in healthcare practices but the duty of care has not changed. The dilemmas for healthcare practitioners thus who have competent patients requesting hastened death extends far beyond acting within a country’s laws as they go to the very heart of the relationship between the practitioner and patient.

Health services across the world increasingly face pressures on the use of expensive hospital services. Better organisation and delivery of primary care has the potential to manage demand and reduce costs for hospital services, but routine primary care services are not open during evenings and weekends. Extended access (evening and weekend opening) is hypothesized to reduce pressure on hospital services from emergency department visits. However, the existing evidence-base is weak, largely focused on emergency out-of-hours services, and analysed using a before-and after-methodology without effective comparators. Throughout 2014, 56 primary care practices (346,024 patients) in Greater Manchester, England, offered 7-day extended access, compared with 469 primary care practices (2,596,330 patients) providing routine access. Extended access included evening and weekend opening and served both urgent and routine appointments. To assess the effects of extended primary care access on hospital services, we apply a difference-in-differences analysis using hospital administrative data from 2011 to 2014. Propensity score matching techniques were used to match practices without extended access to practices with extended access. Differences in the change in "minor" patient-initiated emergency department visits per 1,000 population were compared between practices with and without extended access. Populations registered to primary care practices with extended access demonstrated a 26.4% relative reduction (compared to practices without extended access) in patient-initiated emergency department visits for "minor" problems (95% CI -38.6% to -14.2%, absolute difference: -10,933 per year, 95% CI -15,995 to -5,866), and a 26.6% (95% CI -39.2% to -14.1%) relative reduction in costs of patient-initiated visits to emergency departments for minor problems (absolute difference: -£767,976, -£1,130,767 to -£405,184). There was an insignificant relative reduction of 3.1% in total emergency department visits (95% CI -6.4% to 0.2%). Our results were robust to several sensitivity checks. A lack of detailed cost reporting of the running costs of extended access and an inability to capture health outcomes and other health service impacts constrain the study from assessing the full cost-effectiveness of extended access to primary care. The study found that extending access was associated with a reduction in emergency department visits in the first 12 months. The results of the research have already informed the decision by National Health Service England to extend primary care access across Greater Manchester from 2016. However, further evidence is needed to understand whether extending primary care access is cost-effective and sustainable.

Extended dynamic mode decomposition with dictionary learning: A data-driven adaptive spectral decomposition of the Koopman operator

2017-10-01

Numerical approximation methods for the Koopman operator have advanced considerably in the last few years. In particular, data-driven approaches such as dynamic mode decomposition (DMD)51 and its generalization, the extended-DMD (EDMD), are becoming increasingly popular in practical applications. The EDMD improves upon the classical DMD by the inclusion of a flexible choice of dictionary of observables which spans a finite dimensional subspace on which the Koopman operator can be approximated. This enhances the accuracy of the solution reconstruction and broadens the applicability of the Koopman formalism. Although the convergence of the EDMD has been established, applying the method in practice requires a careful choice of the observables to improve convergence with just a finite number of terms. This is especially difficult for high dimensional and highly nonlinear systems. In this paper, we employ ideas from machine learning to improve upon the EDMD method. We develop an iterative approximation algorithm which couples the EDMD with a trainable dictionary represented by an artificial neural network. Using the Duffing oscillator and the Kuramoto Sivashinsky partical differential equation as examples, we show that our algorithm can effectively and efficiently adapt the trainable dictionary to the problem at hand to achieve good reconstruction accuracy without the need to choose a fixed dictionary a priori. Furthermore, to obtain a given accuracy, we require fewer dictionary terms than EDMD with fixed dictionaries. This alleviates an important shortcoming of the EDMD algorithm and enhances the applicability of the Koopman framework to practical problems.

Perpetuating "scientific motherhood": infant feeding discourse in Parents magazine, 1930-2007.

PubMed

Foss, Katherine A

2010-05-01

Although breastfeeding initiation rates have recently been at an all-time high, duration continues to be considerably low. Given the health benefits associated with extended breastfeeding, this discrepancy is cause for concern. This research examined the messages conveyed about infant feeding in a popular parenting magazine, Parents magazine, from 1930 through 2007. Findings indicated that the messages about infant feeding shifted in accordance with changing ideologies about the means of infant feeding-from bottle-feeding to breastfeeding. However, even with changing attitudes toward infant feeding, writers used scientific evidence and the advice of "experts" to justify the dominant form of feeding. The absence of practical advice regarding breastfeeding challenges, especially from "real" women set up false expectations about the breastfeeding experience, painting it as "natural" and best for the baby. The dependency on experts and lack of practical advice in popular media, like Parents magazine, may help explain a societal trend that downplays breastfeeding obstacles, giving insight into the vast discrepancy between breastfeeding initiation and duration.

Unscientific beliefs about scientific topics in nutrition.

Humans interact with food daily. Such repeated exposure creates a widespread, superficial familiarity with nutrition. Personal familiarity with nutrition from individual and cultural perspectives may give rise to beliefs about food not grounded in scientific evidence. In this summary of the session entitled “Unscientific Beliefs about Scientific Topics in Nutrition,” we discuss accumulated work illustrating and quantifying potentially misleading practices in the conduct and, more so, reporting of nutrition science along with proposed approaches to amelioration. We begin by defining “unscientific beliefs” and from where such beliefs may come, followed by discussing how large bodies of nutritional epidemiologic observations not only create highly improbable patterns of association but implausible magnitudes of implied effect. Poor reporting practices, biases, and methodologic issues that have distorted scientific understandings of nutrition are presented, followed by potential influences of conflicts of interest that extend beyond financial considerations. We conclude with recommendations for improving the conduct, reporting, and communication of nutrition-related research to ground discussions in evidence rather than solely on beliefs.

Occupational UVR skin protection by make-up.

2012-03-01

New legislation has been introduced in the Member States of the European Union, covering worker exposure to artificial optical radiation. Use of make-up could reduce the ultraviolet hazard level and provide additional protection for skin against UV radiation (UVR). This is particularly important in entertainment and filming where intentional exposure of the actors and presenters to the very intense light sources may be required for extended periods of time. This document presents the assessment of UVR protection of make-up used in entertainment and demonstrates that the protection level varies considerably for different luminaires and application techniques. An important practical implication of this finding is that make-up alone cannot be considered as a reliable protection measure against skin exposure to actinic UV.

Inkjet printing is emerging at the forefront of biosensor fabrication technologies. Parallel advances in both ink chemistry and printers have led to a biosensor manufacturing approach that is simple, rapid, flexible, high resolution, low cost, efficient for mass production, and extends the capabilities of devices beyond other manufacturing technologies. Here we review for the first time the factors behind successful inkjet biosensor fabrication, including printers, inks, patterning methods, and matrix types. We discuss technical considerations that are important when moving beyond theoretical knowledge to practical implementation. We also highlight significant advances in biosensor functionality that have been realised through inkjet printing. Finally, we consider future possibilities for biosensors enabled by this novel combination of chemistry and technology.

2011-01-01

Summary The generalized linear mixed-effects model (GLMM) is a popular paradigm to extend models for cross-sectional data to a longitudinal setting. When applied to modeling binary responses, different software packages and even different procedures within a package may give quite different results. In this report, we describe the statistical approaches that underlie these different procedures and discuss their strengths and weaknesses when applied to fit correlated binary responses. We then illustrate these considerations by applying these procedures implemented in some popular software packages to simulated and real study data. Our simulation results indicate a lack of reliability for most of the procedures considered, which carries significant implications for applying such popular software packages in practice.

2017-11-01

Natural convection heat transfer around a horizontal cylinder has received considerable attention through decades since it has been used in several viable applications. However, investigations into passively enhancement of the free convective cooling using external walls and chimney effect are lacking. In this work, a numerical simulation to study natural convection from a horizontal cylinder configured with semicircular shrouds with an expended chimney is employed. The fluid flow and convective heat transfer around the cylinder are modeled. The bare cylinder is also simulated for comparison. The present study are aimed at improving our understanding of the parameters advancing the free convective cooling of the cylinder implemented with the shrouds configuration. For validation, the present results for the bare tube are compared with data reported in the literature. The numerical simulations indicate that applying the shrouds configuration with extended chimney to a tube promotes the convection heat transfer from the cylinder. Such a method is less expensive and simpler in design than other configurations (e.g. utilizing extended surfaces, fins), making the technology more practical for industrial productions, especially for cooling systems.

Learning may need only a few bits of synaptic precision

2016-05-01

Learning in neural networks poses peculiar challenges when using discretized rather then continuous synaptic states. The choice of discrete synapses is motivated by biological reasoning and experiments, and possibly by hardware implementation considerations as well. In this paper we extend a previous large deviations analysis which unveiled the existence of peculiar dense regions in the space of synaptic states which accounts for the possibility of learning efficiently in networks with binary synapses. We extend the analysis to synapses with multiple states and generally more plausible biological features. The results clearly indicate that the overall qualitative picture is unchanged with respect to the binary case, and very robust to variation of the details of the model. We also provide quantitative results which suggest that the advantages of increasing the synaptic precision (i.e., the number of internal synaptic states) rapidly vanish after the first few bits, and therefore that, for practical applications, only few bits may be needed for near-optimal performance, consistent with recent biological findings. Finally, we demonstrate how the theoretical analysis can be exploited to design efficient algorithmic search strategies.

Toward Dynamic Adaptation of Psychological Interventions for Child and Adolescent Development and Mental Health.

Children's and adolescents' mental health needs emphasize the necessity of a new era of translational research to enhance development and yield better lives for children, families, and communities. Developmental, clinical, and translational research serves as a powerful tool for managing the inevitable complexities in pursuit of these goals. This article proposes key ideas that will strengthen current evidence-based intervention practices by creating stronger links between research, practice, and complex systems contexts, with the potential of extending applicability, replicability, and impact. As exemplified in some of the articles throughout this special issue, new research and innovative implementation models will likely contribute to better ways of assessing and dynamically adapting structure and intervention practice within mental health systems. We contend that future models for effective interventions with children and adolescents will involve increased attention to (a) the connection of research on the developmental needs of children and adolescents to practice models; (b) consideration of informed contextual and cultural adaptation in implementation; and (c) a rational model of evidence-based planning, using a dynamic, inclusive approach with high support for adaptation, flexibility, and implementation fidelity. We discuss future directions for translational research for researchers, practitioners, and administrators in the field to continue and transform these ideas and their illustrations.

This study uses a task delegation questionnaire to compare 1973 physician extender practices in seven primary care-oriented sites with a physician attitude survey made in 1969. One additional site using no physician extenders was included as a control. The study involves both major types of physician extenders (physician assistants and nurse practitioners) in ambulatory practices with at least one year of experience in using such personnel. With minor exceptions, actual task delegation patterns conform with the 1969 attitudes of physicians as to which tasks "could and should" be delegated to physician extenders. PMID:2022

Pitfalls of implementing acute care surgery.

Incorporating emergency general surgery into the current practice of the trauma and critical care surgeon carries sweeping implications for future practice and training. Herein, we examine the known benefits of the practice of emergency general surgery, contrast it with the emerging paradigm of acute care surgery, and examine pitfalls already encountered in integration of emergency general surgery into a traditional trauma/critical care surgery service. A MEDLINE literature search was supplemented with local experience and national presentations at major meetings to provide data for this review. Considerations including faculty complement, service structure, resident staffing, physician extenders, the decreased role of community hospitals in providing trauma and emergency general surgery care, and the effects on an elective operative schedule are inadequately explored at present. There are no firm recommendations as to how to incorporate emergency general surgery into a trauma/critical care practice that will satisfy both academic and community practice paradigms. The near future seems likely to embrace the expanded training and clinical care program termed acute care surgery. A host of essential elements have yet to be examined to undertake a critical analysis of the applicability, advisability, and appropriate structure of both emergency general surgery and acute care surgery in the United States. Proceeding along this pathway may be fraught with training, education, and implementation pitfalls that are ideally addressed before deploying acute care surgery as a national standard.

However there are numerous potential risks and complications possible with transfusions, which may outweigh their benefits. Storage of blood products has improved considerably over time but whilst extended storage times may improve their availability, a phenomenon known as the storage lesion has been identified which affects erythrocyte viability and survival. Leukoreduction involves removing leukocytes and platelets thereby preventing their release of cytokines and bioactive compounds which also contribute to storage lesions and certain transfusion reactions. Newer transfusion techniques are being explored such as cell salvage in surgical patients and subsequent autologous transfusion.

During 2009-2012, Avahan, a large donor funded HIV/AIDS prevention program in India was transferred from donor support and operation to government. This transition of approximately 200 targeted interventions (TIs), occurred in three tranches in 2009, 2011 and 2012. This paper reports on the management practices pursued in support of a smooth transition of the program, and addresses the extent to which standard change management practices were employed, and were useful in supporting transition. We conducted structured surveys of a sample of 80 TIs from the 2011 and 2012 rounds of transition. One survey was administered directly before transition and the second survey 12 month after transition. These surveys assessed readiness for transition and practices post-transition. We also conducted 15 case studies of transitioning TIs from all three rounds, and re-visited 4 of these 1-3 years later. Considerable evolution in the nature of relationships between key actors was observed between transition rounds, moving from considerable mistrust and lack of collaboration in 2009 toward a shared vision of transition and mutually respectful relationships between Avahan and government in later transition rounds. Management practices also evolved with the gradual development of clear implementation plans, establishment of the post of "transition manager" at state and national levels, identified budgets to support transition, and a common minimum programme for transition. Staff engagement was important, and was carried out relatively effectively in later rounds. While the change management literature suggests short-term wins are important, this did not appear to be the case for Avahan, instead a difficult first round of transition seemed to signal the seriousness of intentions regarding transition. In the Avahan case a number of management practices supported a smooth transition these included: an extended and sequenced time frame for transition; co-ownership and planning of transition by both donor and government; detailed transition planning and close attention to program alignment, capacity development and communication; engagement of staff in the transition process; engagement of multiple stakeholders post transition to promote program accountability and provide financial support; signaling by actors in charge of transition that they were committed to specified time frames.

Reconsidering nutrition science: critical reflection with a cultural lens

PubMed Central

2014-01-01

Background European culture gave birth to modern science as a means to investigate and explain the natural world. The biomedical disciplines that have since emerged, including nutrition, presuppose a web of basic presuppositions, background assumptions and implicit cultural values that are often overlooked and escape peer review. These "hidden subjectivities" are widely taken-for-granted while exerting a powerful hold on the scope, direction and patterns of disciplinary thought. Nutrition science currently has no accepted means of collectively attending to hidden subjectivities embedded within its methods and practice. Here I propose that directing inquiry into these dimensions holds potential to advance our discipline. Methods This critically reflective approach emerged from critical theory and the practice of cross-cultural engagement (CCE). CCE deliberately seeks out and critically engages food and health understandings of non-European cultures. Its protocol includes cognitive frameshifting, a practice of temporarily stepping outside of habitual thought patterns and into a non-biomedical framework of background assumptions. A cultural lens metaphor derives from CCE practice and is forwarded here as a viable means for restoring critically reflective attention to hidden subjectivities while also inviting further CCE practice within the discipline. Results Critical reflection with a cultural lens allows cognitive attachments to materialism, reductionism, mechanistic thought, naïve realism, control over nature and pervasive subject-object dichotomies between mind and matter, scientist and nature, experience and reality, among many others to become more available for critical consideration. Culturally diverse food and health understandings otherwise dismissed as "unscientific" or held in abeyance gain value as alternative assumptive frameworks and cognitive models that can be temporarily inhabited for further intercultural reflection and insight. Conclusion Critical reflection with a cultural lens allows reconsideration of nutrition science in light of its culturally specific origin and foundation. This perspective can advance the discipline in two ways. First, it extends skeptical inquiry into hidden subjectivities that are otherwise implicit and seldom given over to critical consideration. Second, it can broaden scholarly inquiry through deliberate attempts to cross cognitive boundaries and empathically inhabit different cognitive worlds. This developmental practice holds potential to both deepen and broaden disciplinary inquiry. PMID:24886077

The biomedical disciplines that have since emerged, including nutrition, presuppose a web of basic presuppositions, background assumptions and implicit cultural values that are often overlooked and escape peer review. These "hidden subjectivities" are widely taken-for-granted while exerting a powerful hold on the scope, direction and patterns of disciplinary thought. Nutrition science currently has no accepted means of collectively attending to hidden subjectivities embedded within its methods and practice. Here I propose that directing inquiry into these dimensions holds potential to advance our discipline. This critically reflective approach emerged from critical theory and the practice of cross-cultural engagement (CCE). CCE deliberately seeks out and critically engages food and health understandings of non-European cultures. Its protocol includes cognitive frameshifting, a practice of temporarily stepping outside of habitual thought patterns and into a non-biomedical framework of background assumptions. A cultural lens metaphor derives from CCE practice and is forwarded here as a viable means for restoring critically reflective attention to hidden subjectivities while also inviting further CCE practice within the discipline. Critical reflection with a cultural lens allows cognitive attachments to materialism, reductionism, mechanistic thought, naïve realism, control over nature and pervasive subject-object dichotomies between mind and matter, scientist and nature, experience and reality, among many others to become more available for critical consideration. Culturally diverse food and health understandings otherwise dismissed as "unscientific" or held in abeyance gain value as alternative assumptive frameworks and cognitive models that can be temporarily inhabited for further intercultural reflection and insight. Critical reflection with a cultural lens allows reconsideration of nutrition science in light of its culturally specific origin and foundation. This perspective can advance the discipline in two ways. First, it extends skeptical inquiry into hidden subjectivities that are otherwise implicit and seldom given over to critical consideration. Second, it can broaden scholarly inquiry through deliberate attempts to cross cognitive boundaries and empathically inhabit different cognitive worlds. This developmental practice holds potential to both deepen and broaden disciplinary inquiry.

The ubiquitous use of communication technologies has led to an expectation that a similar approach should extend to health care. Despite considerable rhetoric about the need for general practices to offer alternatives to face-to-face consultations, such as telephone, email, and internet video consultations, the extent to which such technologies are actually used at present is unclear. The aim of the survey was to identify the frequency and range of ways in which general practices are providing (or planning) alternatives to face-to-face consultations. A postal survey of practices around Bristol, Oxford, Lothian, the Highlands, and the Western Isles of Scotland. A postal questionnaire survey was sent to each of the GPs and practice managers of 421 practices between January and May 2015. A response was received from 319/421 practices (76%). Although the majority of the practices reported that they were conducting telephone consultations frequently (n = 211/318, 66%), fewer were implementing email consultations (n = 18/318, 6%), and most (n = 169/318, 53%) had no plans to introduce this. None were currently using internet video, and 86% (n = 273/318) had no plans to introduce internet video consultations. These findings were repeated in the reported use of alternatives to face-to-face consultations at an individual GP level. Optional free text responses were completed by 28% of responders, and offered an explanation for the (often perceived) barriers and incentives for implementation. Despite policy pressure to introduce consultations by email and internet video, there is a general reluctance among GPs to implement alternatives to face-to-face consultations. This identifies a substantial gap between rhetoric and reality in terms of the likelihood of certain alternatives (email, video) changing practice in the near future. © British Journal of General Practice 2016.

Risk Evaluation and Mitigation Strategies (REMS) for extended-release and long-acting opioid analgesics: considerations for palliative care practice.

PubMed

Gudin, Jeffrey

2012-06-01

Prescription opioid analgesics are an essential treatment option for patients with moderate to severe pain. Over the last decade the increased medical use of these agents has contributed to a public health epidemic of abuse, addiction, and overdose-related deaths. These medications remain mainstays in both primary care and pain management practices. As palliative services are incorporated at earlier stages of the disease process and the number of individuals with chronic illness increases, palliative care specialists may encounter an increasing number of patients with opioid abuse and addiction problems. Extended-release (ER) and long-acting (LA) opioid formulations are administered to patients with moderate to severe chronic pain requiring around-the-clock analgesia. Given the large quantity of active ingredient contained within some dosage strengths, this medication class is associated with serious risks when taken improperly. In response to growing reports of abuse and overdose deaths, the US Food and Drug Administration (FDA) announced the need for a risk mitigation strategy for the entire class of medication. The class-wide Risk Evaluation and Mitigation Strategy (REMS) for ER/LA opioids will emphasize prescriber training and patient education to ensure that the therapeutic benefits outweigh the risks of addiction, unintentional overdose, and death. As primary care, pain management, and palliative care clinicians often encounter patients who require ER/LA opioids, an understanding of the suggested requirements and potential impact of this regulation is essential.

Extended opening hours and patient experience of general practice in England: multilevel regression analysis of a national patient survey

PubMed Central

Cowling, Thomas E; Harris, Matthew; Majeed, Azeem

2017-01-01

Background The UK government plans to extend the opening hours of general practices in England. The ‘extended hours access scheme’ pays practices for providing appointments outside core times (08:00 to 18.30, Monday to Friday) for at least 30 min per 1000 registered patients each week. Objective To determine the association between extended hours access scheme participation and patient experience. Methods Retrospective analysis of a national cross-sectional survey completed by questionnaire (General Practice Patient Survey 2013–2014); 903 357 survey respondents aged ≥18 years old and registered to 8005 general practices formed the study population. Outcome measures were satisfaction with opening hours, experience of making an appointment and overall experience (on five-level interval scales from 0 to 100). Mean differences between scheme participation groups were estimated using multilevel random-effects regression, propensity score matching and instrumental variable analysis. Results Most patients were very (37.2%) or fairly satisfied (42.7%) with the opening hours of their general practices; results were similar for experience of making an appointment and overall experience. Most general practices participated in the extended hours access scheme (73.9%). Mean differences in outcome measures between scheme participants and non-participants were positive but small across estimation methods (mean differences ≤1.79). For example, scheme participation was associated with a 1.25 (95% CI 0.96 to 1.55) increase in satisfaction with opening hours using multilevel regression; this association was slightly greater when patients could not take time off work to see a general practitioner (2.08, 95% CI 1.53 to 2.63). Conclusions Participation in the extended hours access scheme has a limited association with three patient experience measures. This questions expected impacts of current plans to extend opening hours on patient experience. PMID:27343274

Approaches to the vaccination of pregnant women: experience from Stockport, UK, with prenatal influenza.

PubMed

Baxter, David

2013-06-01

For the 2010/11 influenza season the prenatal vaccination program was extended to all women in England and Wales irrespective of gestational age--this was a considerable shift in practice for both pregnant women and healthcare providers where the emphasis previously had been only on targeted vaccination for pregnant women with adverse risk factors for influenza infection. This paper will describe the program's operation in Stockport, UK during this season when uptake was among the highest in the England and Wales. Stockport is situated in the south east of Greater Manchester. It is a generally affluent area with a population of 295,000. Health indicators are generally higher than the regional average. The target population for influenza is just under 50,000 residents (excluding pregnant women).

Input and output constraints-based stabilisation of switched nonlinear systems with unstable subsystems and its application

NASA Astrophysics Data System (ADS)

Chen, Chao; Liu, Qian; Zhao, Jun

2018-01-01

This paper studies the problem of stabilisation of switched nonlinear systems with output and input constraints. We propose a recursive approach to solve this issue. None of the subsystems are assumed to be stablisable while the switched system is stabilised by dual design of controllers for subsystems and a switching law. When only dealing with bounded input, we provide nested switching controllers using an extended backstepping procedure. If both input and output constraints are taken into consideration, a Barrier Lyapunov Function is employed during operation to construct multiple Lyapunov functions for switched nonlinear system in the backstepping procedure. As a practical example, the control design of an equilibrium manifold expansion model of aero-engine is given to demonstrate the effectiveness of the proposed design method.

Healthy ageing.

PubMed

Sims, Jane

The increasing number of people reaching their 80s and 90s has triggered multidisciplinary consideration of how to address and capitalise on the longevity phenomenon. The aim of this article is to provide an overview of ways in which clinicians can work with older patients to optimise their health and wellbeing during the later years of life. Old age need not be burdensome to individuals or society. There is strong evidence to support the management of many chronic diseases presenting in - or extending into - old age. General practice will need to adapt to the demographic challenges of an ageing population by targeting conditions that impede people from contributing to family and societal life. General practitioners (GPs) will also need to adapt to the changing expectations of, and from, older patients across the upcoming generations.

On fitting generalized linear mixed-effects models for binary responses using different statistical packages.

2011-09-10

The generalized linear mixed-effects model (GLMM) is a popular paradigm to extend models for cross-sectional data to a longitudinal setting. When applied to modeling binary responses, different software packages and even different procedures within a package may give quite different results. In this report, we describe the statistical approaches that underlie these different procedures and discuss their strengths and weaknesses when applied to fit correlated binary responses. We then illustrate these considerations by applying these procedures implemented in some popular software packages to simulated and real study data. Our simulation results indicate a lack of reliability for most of the procedures considered, which carries significant implications for applying such popular software packages in practice.

New transmission scheme to enhance throughput of DF relay network using rate and power adaptation

NASA Astrophysics Data System (ADS)

Taki, Mehrdad; Heshmati, Milad

2017-09-01

This paper presents a new transmission scheme for a decode and forward (DF) relay network using continuous power adaptation while independent average power constraints are provisioned for each node. To have analytical insight, the achievable throughputs are analysed using continuous adaptation of the rates and the powers. As shown by numerical evaluations, a considerable outperformance is seen by continuous power adaptation compared to the case where constant powers are utilised. Also for practical systems, a new throughput maximised transmission scheme is developed using discrete rate adaptation (adaptive modulation and coding) and continuous transmission power adaptation. First a 2-hop relay network is considered and then the scheme is extended for an N-hop network. Numerical evaluations show the efficiency of the designed schemes.

A Consideration on the Future Direction of Japanese Educational System About Fostering Human Resources for the Global Society

The lectures are taken, making use of the textbook of the same contents, for high school students in Japan, students at Yamagata University and at Korea Maritime University in Korea. I’ ll find the similarity and difference, by comparing vertical and horizontal relations among three groups. As a result, I can find the directionality of cultivating human resources of doing well in the global society. I think there is “Matrix Thinking Frame” as one of the effective countermeasures for fostering men of ability. It is possible to part from conventional passiveness type education, according to planning and practicing one’ s “Life Management Plan” by using this system. The case where one’ s capability has been extended appears in students, as above mentioned.

When policy meets physiology: the challenge of reducing resident work hours.

PubMed

Lockley, Steven W; Landrigan, Christopher P; Barger, Laura K; Czeisler, Charles A

2006-08-01

Considerable controversy exists regarding optimal work hours for physicians and surgeons in training. In a series of studies, we assessed the effect of extended work hours on resident sleep and health as well as patient safety. In a validated nationwide survey, we found that residents who had worked 24 hours or longer were 2.3 times more likely to have a motor vehicle crash following that shift than when they worked < 24 hours, and that the monthly risk of a crash increased by 16.2% after each extended duration shift. We also found in a randomized trial that interns working a traditional on-call schedule slept 5.8 hours less per week, had twice as many attentional failures on duty overnight, and made 36% more serious medical errors and nearly six times more serious diagnostic errors than when working on a schedule that limited continuous duty to 16 hours. While numerous opinions have been published opposing reductions in extended work hours due to concerns regarding continuity of patient care, reduced educational opportunities, and traditionally-defined professionalism, there are remarkably few objective data in support of continuing to schedule medical trainees to work shifts > 24 hours. An evidence-based approach is needed to minimize the well-documented risk that current work hour practices confer on resident health and patient safety while optimizing education and continuity of care.

Follow-up of early stage melanoma: specialist clinician perspectives on the functions of follow-up and implications for extending follow-up intervals.

There is limited evidence on the relative effectiveness of different follow-up schedules for patients with AJCC stage I or II melanoma, but less frequent follow-up than is currently recommended has been proposed. To describe melanoma clinicians' perspectives on the functions of follow-up, factors that influence follow-up intervals, and important considerations for extending intervals. Qualitative interviews with 16 clinicians (surgical oncologists, dermatologists, melanoma unit physicians) who conduct follow-up at two of Australia's largest specialist centers. Follow-up is conducted for early detection of recurrences or new primary melanomas, to manage patient anxiety, support patient self-care, and as part of shared care. Recommended intervals are based on guidelines but account for each patient's clinical risk profile, level of anxiety, patient education requirements, capacity to engage in skin self-examination, and how the clinician prefers to manage any suspicious lesions. To revise guidelines and implement change it is important to understand the rationale underpinning existing practice. Extended follow-up intervals for early stage melanoma are more likely to be adopted after the first year when patients are less anxious and sufficiently prepared to conduct self-examination. Clinicians may retain existing schedules for highly anxious patients or those unable to examine themselves. Copyright © 2012 Wiley Periodicals, Inc.

Record keeping in Norwegian general practice.

PubMed

Lönberg, N C; Bentsen, B G

1984-11-01

Routines of medical record keeping were studied in a random sample of 50 out of 228 general practitioners in two counties, Möre & Romsdal and Sör-Tröndelag. One doctor refused to participate and one had retired. The 48 physicians were interviewed and a questionnaire was completed with details about their record keeping. The standard of the records was assessed according to legibility, quality of notes, past history and tidiness using a score system. All general practitioners had records for every patient, but the quality of the records varied considerably. More than 50 per cent used handwriting in progress notes, which varied from diagnostic labels to extended reports. Few records contained accessible background information about the patient concerned, and many records contained large amounts of old and irrelevant papers. The record-scores varied from 3 to maximum 10 with an average of 6.7. Higher Standards of recording in general practice are called for, since the quality of records does not only affect the individual patient, but, in the end, the quality of medical care in general.

A discontinuous Galerkin approach for conservative modeling of fully nonlinear and weakly dispersive wave transformations

NASA Astrophysics Data System (ADS)

Sharifian, Mohammad Kazem; Kesserwani, Georges; Hassanzadeh, Yousef

2018-05-01

This work extends a robust second-order Runge-Kutta Discontinuous Galerkin (RKDG2) method to solve the fully nonlinear and weakly dispersive flows, within a scope to simultaneously address accuracy, conservativeness, cost-efficiency and practical needs. The mathematical model governing such flows is based on a variant form of the Green-Naghdi (GN) equations decomposed as a hyperbolic shallow water system with an elliptic source term. Practical features of relevance (i.e. conservative modeling over irregular terrain with wetting and drying and local slope limiting) have been restored from an RKDG2 solver to the Nonlinear Shallow Water (NSW) equations, alongside new considerations to integrate elliptic source terms (i.e. via a fourth-order local discretization of the topography) and to enable local capturing of breaking waves (i.e. via adding a detector for switching off the dispersive terms). Numerical results are presented, demonstrating the overall capability of the proposed approach in achieving realistic prediction of nearshore wave processes involving both nonlinearity and dispersion effects within a single model.

The management of new primary care organizations: an international perspective.

PubMed

Meads, Geoffrey; Wild, Andrea; Griffiths, Frances; Iwami, Michiyo; Moore, Phillipa

2006-08-01

Management practice arising from parallel policies for modernizing health systems is examined across a purposive sample of 16 countries. In each, novel organizational developments in primary care are a defining feature of the proposed future direction. Semistructured interviews with national leaders in primary care policy development and local service implementation indicate that management strategies, which effectively address the organized resistance of medical professions to modernizing policies, have these four consistent characteristics: extended community and patient participation models; national frameworks for interprofessional education and representation; mechanisms for multiple funding and accountabilities; and the diversification of non-governmental organizations and their roles. The research, based on a two-year fieldwork programme, indicates that at the meso-level of management planning and practice, there is a considerable potential for exchange and transferable learning between previously unconnected countries. The effectiveness of management strategies abroad, for example, in contexts where for the first time alternative but comparable new primary care organizations are exercising responsibilities for local resource utilization, may be understood through the application of stakeholder analyses, such as those employed to promote parity of relationships in NHS primary care trusts.

Teaching scientific thinking skills: Students and computers coaching each other

NASA Astrophysics Data System (ADS)

Reif, Frederick; Scott, Lisa A.

1999-09-01

Our attempts to improve physics instruction have led us to analyze thought processes needed to apply scientific principles to problems—and to recognize that reliable performance requires the basic cognitive functions of deciding, implementing, and assessing. Using a reciprocal-teaching strategy to teach such thought processes explicitly, we have developed computer programs called PALs (P_ersonal A_ssistants for L_earning) in which computers and students alternately coach each other. These computer-implemented tutorials make it practically feasible to provide students with individual guidance and feedback ordinarily unavailable in most courses. We constructed PALs specifically designed to teach the application of Newton's laws. In a comparative experimental study these computer tutorials were found to be nearly as effective as individual tutoring by expert teachers—and considerably more effective than the instruction provided in a well-taught physics class. Furthermore, almost all of the students using the PALs perceived them as very helpful to their learning. These results suggest that the proposed instructional approach could fruitfully be extended to improve instruction in various practically realistic contexts.

The integration of behavioral health interventions in children's health care: services, science, and suggestions.

PubMed

Kolko, David J; Perrin, Ellen

2014-01-01

Because the integration of mental or behavioral health services in pediatric primary care is a national priority, a description and evaluation of the interventions applied in the healthcare setting is warranted. This article examines several intervention research studies based on alternative models for delivering behavioral health care in conjunction with comprehensive pediatric care. This review describes the diverse methods applied to different clinical problems, such as brief mental health skills, clinical guidelines, and evidence-based practices, and the empirical outcomes of this research literature. Next, several key treatment considerations are discussed to maximize the efficiency and effectiveness of these interventions. Some practical suggestions for overcoming key service barriers are provided to enhance the capacity of the practice to deliver behavioral health care. There is moderate empirical support for the feasibility, acceptability, and clinical utility of these interventions for treating internalizing and externalizing behavior problems. Practical strategies to extend this work and address methodological limitations are provided that draw upon recent frameworks designed to simplify the treatment enterprise (e.g., common elements). Pediatric primary care has become an important venue for providing mental health services to children and adolescents due, in part, to its many desirable features (e.g., no stigma, local setting, familiar providers). Further adaptation of existing delivery models may promote the delivery of effective integrated interventions with primary care providers as partners designed to address mental health problems in pediatric healthcare.

Exploring extended scope of practice in dietetics: A systems approach.

Ryan, Dominique; Pelly, Fiona; Purcell, Elizabeth

2017-09-01

The aim of this study was to explore health professionals' perceptions of an extended scope of a practice clinic, and develop a framework using a systems approach to facilitate extended scope models across various health settings. A qualitative investigation using semi-structured interviews with four health professionals involved in an extended scope dietitian-led gastroenterology clinic in a hospital in regional Queensland was conducted. A case study design was utilised to investigate interviewees' perceptions of the clinic. Participants were conveniently, purposively sampled. Transcript analysis involved a descriptive analytical approach. Interviewee responses were coded and categorised into themes, and investigator triangulation was used to ensure consistency between individual analyses. A secondary interpretative analysis was conducted where relationships between key themes were mapped to the Systems Engineering Initiative for Patient Safety work system model. Interviewees identified various factors as vital inputs to the work system. These were categorised into the four key elements: stakeholder support, resources, planning and the dietitian. Clinic outcomes were categorised into the impact on four key groups: patients, the dietitian, the multidisciplinary team and the health system. Mapping of the relationships between inputs and outcomes resulted in an implementation framework for extended scope of practice. Extended scope of practice in dietetics may provide positive outcomes for various stakeholders. However, further development of extended scope roles for dietitians requires increased advocacy and support from governments, professional bodies, training institutions and dietitians. We have developed an implementation framework which can be utilised by health professionals interested in embracing an extended scope model of care. © 2016 Dietitians Association of Australia.

Recent Science Highlights of the Van Allen Probes Mission

Ukhorskiy, Aleksandr

2016-10-01

The morning of 30 August 2012 saw an Atlas 5 rocket launch NASA's second Living With a Star spacecraft mission, the twin Radiation Belt Storm Probes, into an elliptic orbit cutting through Earth's radiation belts. Renamed the Van Allen Probes soon after launch, the Probes are designed to determine how the highly variable populations of high-energy charged particles within the radiation belts, dangerous to astronauts and satellites, are created, respond to solar variations, and evolve in space environments. The Van Allen Probes mission extends beyond the practical considerations of the hazard's of Earth's space environment. Twentieth century observations of space and astrophysical systems throughout the solar system and out into the observable universe have shown that the processes that generate intense particle radiation within magnetized environments such as Earth's are universal. During its mission the Van Allen Probes verified and quantified previously suggested energization processes, discovered new energization mechanisms, revealed the critical importance of dynamic plasma injections into the innermost magnetosphere, and used uniquely capable instruments to reveal inner radiation belt features that were all but invisible to previous sensors. This paper gives a brief overview of the mission, presents some recent science highlights, and discusses plans for the extended mission.

US Food and Drug Administration's Risk Evaluation and Mitigation Strategy for extended-release and long-acting opioids: pros and cons, and a European perspective.

PubMed

Mercadante, Sebastiano; Craig, David; Giarratano, Antonello

2012-12-24

Prescriptions for opioid analgesics to manage moderate-to-severe chronic non-cancer pain have increased markedly over the last decade. An unintentional consequence of greater prescription opioid utilization has been the parallel increase in misuse, abuse and overdose, which are serious risks associated with all opioid analgesics. In response to disturbing rises in prescription opioid abuse, the US Food and Drug Administration (FDA) has proposed the implementation of aggressive Risk Evaluation and Mitigation Strategies (REMS). While REMS could dramatically change the development, release, marketing and prescription of extended-release opioids, questions remain on how these programmes may influence prescribing practices, patient safety and ultimately patient access to these agents. The extent of the availability and misuse of prescription opioids in Europe is difficult to assess from the data currently available, due in large part to the considerable differences in prescribing patterns and regulations between countries. Balancing the availability of prescription opioids for those patients who have pain, while discouraging illicit use, is a complex challenge and requires effective efforts on many levels, particularly in Europe where policies are quite different between countries.

Introduction to polymer-based solid-contact ion-selective electrodes-basic concepts, practical considerations, and current research topics.

PubMed

Bieg, Christoph; Fuchsberger, Kai; Stelzle, Martin

2017-01-01

This review aims at providing an introductory overview for researchers new to the field of ion-selective electrodes. Both state of the art technology and novel developments towards solid-contact reference (sc-RE) and solid-contact ion selective electrodes (sc-ISE) are discussed. This technology has potentially widespread and important applications provided certain performance criteria can be met. We present basic concepts, operation principles, and theoretical considerations with regard to their function. Analytical performance and suitability of sc-RE and sc-ISE for a given application depend on critical parameters, which are discussed in this review. Comprehensive evaluation of sensor performance along this set of parameters is considered indispensable to allow for a well-founded comparison of different technologies. Methods and materials employed in the construction of sc-RE and sc-ISE, in particular the solid contact and the polymer membrane composite, are presented and discussed in detail. Operation principles beyond potentiometry are mentioned, which would further extend the field of ISE application. Finally, we conclude by directing the reader to important areas for further scientific research and development work considered particularly critical and promising for advancing this field in sensor R&D.

Pallock, Linda L; Lamborn, Susie D

2006-10-01

This study examined adolescents' perceptions of parenting practices and extended kinship support in relation to academic adjustment for 104 African American and 60 European American 9th and 10th graders (14 and 15 year olds). For African-American teens, parental acceptance was associated with school values, teacher bonding, and work orientation. Higher levels of behavioral control and lower levels of psychological control were associated with a stronger work orientation. After accounting for the demographic variables and the three parenting practices, higher levels of extended kinship support related to stronger school values, higher teacher bonding, and a stronger work orientation. For European-American teens, parental acceptance related to academic adjustment, including stronger school values, higher teacher bonding, and a stronger work orientation. European-American adolescents with stronger extended kinship networks reported higher teacher bonding and a stronger work orientation. Results indicate the importance of extended kinship support for both African-American and European-American adolescents.

Physiotherapy Practice: Opportunities for International Collaboration on Workforce Reforms, Policy and Research.

Grimmer, K; Morris, J; Kim, S; Milanese, S; Fletcher, W

2017-07-01

Physiotherapy or Physical Therapy (PT) is the most commonly practised allied health discipline globally. International PT workforce reforms are underway to deal with increasing patient numbers, shrinking medical and nursing workforces and lengthy waiting lists. It is timely to consider international differences in PT, with the aims of identifying opportunities for shared learning and forming stronger international alliances to support consistent and evidence-based workforce reforms. This paper synthesizes freely available information on PT training and service delivery across the UK, Australia and United States (California). The paper considers differences in roles, workplaces, training, legislation and registration, continuing professional development, and accountability. There are similarities between UK, Australia and United States (California) in many areas of PT roles, training, registration, legislation and professional practice. However, none has a standard national mechanism by which to demonstrate PT accountability, patient safety or quality care. Moreover, there are different approaches to workforce reforms. There is considerable duplication in physiotherapy governance. There are opportunities for targeted international collaborations regarding workforce reforms such as extending scope of practice, and determining and implementing internationally agreed ways of demonstrating PT accountability. The findings of this review have significant policy implications, and identify areas for collaborative research. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Aligning policing and public health promotion: Insights from the world of foot patrol

Wood, Jennifer D.; Taylor, Caitlin J.; Groff, Elizabeth R.; Ratcliffe, Jerry H.

Foot patrol work is rarely described in relation to public health, even though police routinely encounter health risk behaviors and environments. Through a qualitative study of foot patrol policing in violent ‘hotspots’ of Philadelphia, we explore some prospects and challenges associated with bridging security and public health considerations in law enforcement. Noting existing efforts to help advance police officer knowledge of, and attitudes toward health vulnerabilities, we incorporate perspectives from environmental criminology to help advance this bridging agenda. Extending the notion of capable guardianship to understand foot patrol work, we suggest that the way forward for theory, policy and practice is not solely to rely on changing officer culture and behavior, but rather to advance a wider agenda for enhancing collective guardianship, and especially ‘place management’ for harm reduction in the city.

2002-08-01

How did the 1995 Oklahoma City bombing differ from prior disasters and what implications did it have for disaster mental health services and service delivery? The federal disaster mental health approach in this country developed largely out of experiences with natural disasters. The 1995 Oklahoma City bombing differed in several important ways, including the large number of human casualties, higher rates of psychopathology, and an extended period of concern due to the criminal investigation and trials, which suggested the need to consider modifications in the program. Outreach was extensive, but psychiatric morbidity of direct victims was greater than that of victims of natural disasters, emphasizing the need for attention to the triage and referral process. Other concerns that warrant consideration include practices related to record keeping and program evaluation.

Nudging the obese: a UK-US consideration.

PubMed

Oliver, Adam; Ubel, Peter

2014-07-01

Over recent years, nudge policies have become increasingly popular (if somewhat confused) internationally. This article attempts to clarify what a nudge entails, and critically summarises some of the nudge policies that have been proposed to motivate weight loss in the United Kingdom and the United States. Despite the fact that most of the evidence on nudge-related policy has so far been produced in the United States, and that the leading nudge champions are American, the United Kingdom, at least with respect to considering policy interventions of this kind at the national level, appears to be relatively advanced. That said, nudge interventions remain of marginal practical import everywhere, and are never going to solve completely the obesity problem. Nonetheless, even a marginal effect may extend and improve many lives, a result that would satisfy most behavioural economists.

New developments in social interdependence theory.

PubMed

Johnson, David W; Johnson, Roger T

2005-11-01

Social interdependence theory is a classic example of the interaction of theory, research, and practice. The premise of the theory is the way that goals are structured determines how individuals interact, which in turn creates outcomes. Since its formulation nearly 60 years ago, social interdependence theory has been modified, extended, and refined on the basis of the increasing knowledge about, and application of, the theory. Researchers have conducted over 750 research studies on the relative merits of cooperative, competitive, and individualistic efforts and the conditions under which each is appropriate. Social interdependence theory has been widely applied, especially in education and business. These applications have resulted in revisions of the theory and the generation of considerable new research. The authors critically analyze the new developments resulting from extensive research on, and wide-scale applications of, social interdependence theory.

Sci-Fri PM: Radiation Therapy, Planning, Imaging, and Special Techniques - 10: Results from Canada Wide Survey on Total Body Irradiation Practice

DOE Office of Scientific and Technical Information (OSTI.GOV)

Studinski, Ryan; Fraser, Danielle; Samant, Rajiv

Purpose: Total Body Irradiation (TBI) is delivered to a relatively small number of patients with a variety of techniques; it has been a challenge to develop consensus studies for best practice. This survey was created to assess the current state of TBI in Canada. Methods: The survey was created with questions focusing on the radiation prescription, delivery technique and resources involved. The survey was circulated electronically to the heads of every clinical medical physics department in Canada. Responses were gathered and collated, and centres that were known to deliver TBI were urged to respond. Results: Responses from 20 centres weremore » received, including 12 from centres that perform TBI. Although a variety of TBI dose prescriptions were reported, 12 Gy in 6 fractions was used in 11 centres while 5 centres use unique prescriptions. For dose rate, a range of 9 to 51 cGy/min was reported. Most centres use an extended SSD technique, with the patient standing or lying down against a wall. The rest use either a “sweeping” technique or a more complicated multi-field technique. All centres but one indicated that they shield the lungs, and only a minority shield other organs. The survey also showed that considerable resources are used for TBI including extra staffing, extended planning and treatment times and the use of locally developed hardware or software. Conclusions: This survey highlights that both similarities and important discrepancies exist between TBI techniques across the country, and is an opportunity to prompt more collaboration between centres.« less

The care of pediatric patients requires special considerations that are often not addressed in the literature. Relatively straightforward tasks such as clinical evaluation, antibiotic use, splinting, wound closure, and care of simple burns become complicated in the pediatric population for several reasons. The authors seek to demystify some of these topics using the senior author's years of clinical experience treating pediatric patients by giving practical advice and general considerations when treating children.

Operating health analysis of electric power systems

NASA Astrophysics Data System (ADS)

Fotuhi-Firuzabad, Mahmud

The required level of operating reserve to be maintained by an electric power system can be determined using both deterministic and probabilistic techniques. Despite the obvious disadvantages of deterministic approaches there is still considerable reluctance to apply probabilistic techniques due to the difficulty of interpreting a single numerical risk index and the lack of sufficient information provided by a single index. A practical way to overcome difficulties is to embed deterministic considerations in the probabilistic indices in order to monitor the system well-being. The system well-being can be designated as healthy, marginal and at risk. The concept of system well-being is examined and extended in this thesis to cover the overall area of operating reserve assessment. Operating reserve evaluation involves the two distinctly different aspects of unit commitment and the dispatch of the committed units. Unit commitment health analysis involves the determination of which unit should be committed to satisfy the operating criteria. The concepts developed for unit commitment health, margin and risk are extended in this thesis to evaluate the response well-being of a generating system. A procedure is presented to determine the optimum dispatch of the committed units to satisfy the response criteria. The impact on the response wellbeing being of variations in the margin time, required regulating margin and load forecast uncertainty are illustrated. The effects on the response well-being of rapid start units, interruptible loads and postponable outages are also illustrated. System well-being is, in general, greatly improved by interconnection with other power systems. The well-being concepts are extended to evaluate the spinning reserve requirements in interconnected systems. The interconnected system unit commitment problem is decomposed into two subproblems in which unit scheduling is performed in each isolated system followed by interconnected system evaluation. A procedure is illustrated to determine the well-being indices of the overall interconnected system. Under normal operating conditions, the system may also be able to carry a limited amount of interruptible load on top of its firm load without violating the operating criterion. An energy based approach is presented to determine the optimum interruptible load carrying capability in both the isolated and interconnected systems. Composite system spinning reserve assessment and composite system well-being are also examined in this research work. The impacts on the composite well-being of operating reserve considerations such as stand-by units, interruptible loads and the physical locations of these resources are illustrated. It is expected that the well-being framework and the concepts developed in this research work will prove extremely useful in the new competitive utility environment.

Ethical and clinical practice considerations for genetic counselors related to direct-to-consumer marketing of genetic tests.

PubMed

Wade, Christopher H; Wilfond, Benjamin S

2006-11-15

Several companies utilize direct-to-consumer (DTC) advertising for genetic tests and some, but not all, bypass clinician involvement by offering DTC purchase of the tests. This article examines how DTC marketing strategies may affect genetic counselors, using available cardiovascular disease susceptibility tests as an illustration. The interpretation of these tests is complex and includes consideration of clinical validity and utility, and the further complications of gene-environment interactions and pleiotropy. Although it is unclear to what extent genetic counselors will encounter clients who have been exposed to DTC marketing strategies, these strategies may influence genetic counseling interactions if they produce directed interest in specific tests and unrealistic expectations for the tests' capacity to predict disease. Often, a client's concern about risk for cardiovascular diseases is best addressed by established clinical tests and a family history assessment. Ethical dilemmas may arise for genetic counselors who consider whether to accept clients who request test interpretation or to order DTC-advertised tests that require a clinician's authorization. Genetic counselors' obligations to care for clients extend to interpreting DTC tests, although this obligation may be fulfilled by referral or consultation with specialists. Genetic counselors do not have an obligation to order DTC-advertised tests that have minimal clinical validity and utility at a client's request. This can be a justified restriction on autonomy based on consideration of risks to the client, the costs, and the implications for society. Published 2006 Wiley-Liss, Inc.

Making working memory work: The effects of extended practice on focus capacity and the processes of updating, forward access, and random access

Price, John M.; Colflesh, Gregory J. H.; Cerella, John; Verhaeghen, Paul

2014-01-01

We investigated the effects of 10 hours of practice on variations of the N-Back task to investigate the processes underlying possible expansion of the focus of attention within working memory. Using subtractive logic, we showed that random access (i.e., Sternberg-like search) yielded a modest effect (a 50% increase in speed) whereas the processes of forward access (i.e., retrieval in order, as in a standard N-Back task) and updating (i.e., changing the contents of working memory) were executed about 5 times faster after extended practice. We additionally found that extended practice increased working memory capacity as measured by the size of the focus of attention for the forward-access task, but not for variations where probing was in random order. This suggests that working memory capacity may depend on the type of search process engaged, and that certain working-memory-related cognitive processes are more amenable to practice than others.

There is a core body of knowledge, experience, and skills integral to facilitating auditory, speech, and spoken language development when working with the general population of students who are deaf and hard of hearing. There are additional issues, strategies, and challenges inherent in speech habilitation/rehabilitation practices essential to the population of deaf and hard of hearing students who also use sign language. This article will highlight philosophical and practical considerations related to practices used to facilitate spoken language development and associated literacy skills for children and adolescents who sign. It will discuss considerations for planning and implementing practices that acknowledge and utilize a student's abilities in sign language, and address how to link these skills to developing and using spoken language. Included will be considerations for children from early childhood through high school with a broad range of auditory access, language, and communication characteristics.

A high gain energy amplifier operated with fast neutrons

DOE Office of Scientific and Technical Information (OSTI.GOV)

Rubbia, C.

1995-10-01

The basic concept and the main practical considerations of an Energy Amplifier (EA) have been exhaustively described elsewhere. Here the concept of the EA is further explored and additional schemes are described which offer a higher gain, a larger maximum power density and an extended burn-up. All these benefits stem from the use of fast neutrons, instead of thermal or epithermal ones, which was the case in the original study. The higher gain is due both to a more efficient high energy target configuration and to a larger, practical value of the multiplication factor. The higher power density results frommore » the higher permissible neutron flux, which in turn is related to the reduced rate of {sup 233}Pa neutron captures (which, as is well known, suppress the formation of the fissile {sup 233}U fuel) and the much smaller k variations after switch-off due to {sup 233}Pa decays for a given burn-up rate. Finally a longer integrated burn-up is made possible by reduced capture rate by fission fragments of fast neutrons. In practice a 20 MW proton beam (20 mA @ 1 GeV) accelerated by a cyclotron will suffice to operate a compact EA at the level of {approx} 1 GW{sub e}. The integrated fuel burn-up can be extended in excess of 100 GW d/ton, limited by the mechanical survival of the fuel elements. Radio-Toxicity accumulated at the end of the cycle is found to be largely inferior to the one of an ordinary Reactor for the same energy produced. Schemes are proposed which make a {open_quotes}melt-down{close_quotes} virtually impossible. The conversion ratio, namely the rate of production of {sup 233}U relative to consumption is generally larger than unity, which permits production of fuel for other uses. Alternatively the neutron excess can be used to transform unwanted {open_quotes}ashes{close_quotes} into more acceptable elements.« less

Alginate-Encapsulation for the Improved Hypothermic Preservation of Human Adipose-Derived Stem Cells

PubMed Central

Swioklo, Stephen; Constantinescu, Andrei

2016-01-01

Despite considerable progress within the cell therapy industry, unmet bioprocessing and logistical challenges associated with the storage and distribution of cells between sites of manufacture and the clinic exist. We examined whether hypothermic (4°C–23°C) preservation of human adipose-derived stem cells could be improved through their encapsulation in 1.2% calcium alginate. Alginate encapsulation improved the recovery of viable cells after 72 hours of storage. Viable cell recovery was highly temperature-dependent, with an optimum temperature of 15°C. At this temperature, alginate encapsulation preserved the ability for recovered cells to attach to tissue culture plastic on rewarming, further increasing its effect on total cell recovery. On attachment, the cells were phenotypically normal, displayed normal growth kinetics, and maintained their capacity for trilineage differentiation. The number of cells encapsulated (up to 2 × 106 cells per milliliter) did not affect viable cell recovery nor did storage of encapsulated cells in a xeno-free, serum-free,current Good Manufacturing Practice-grade medium. We present a simple, low-cost system capable of enhancing the preservation of human adipose-derived stem cells stored at hypothermic temperatures, while maintaining their normal function. The storage of cells in this manner has great potential for extending the time windows for quality assurance and efficacy testing, distribution between the sites of manufacture and the clinic, and reducing the wastage associated with the limited shelf life of cells stored in their liquid state. Significance Despite considerable advancement in the clinical application of cell-based therapies, major logistical challenges exist throughout the cell therapy supply chain associated with the storage and distribution of cells between the sites of manufacture and the clinic. A simple, low-cost system capable of preserving the viability and functionality of human adipose-derived stem cells (a cell with substantial clinical interest) at hypothermic temperatures (0°C–32°C) is presented. Such a system has considerable potential for extending the shelf life of cell therapy products at multiple stages throughout the cell therapy supply chain. PMID:26826163

Legal, ethical and practical considerations in research involving nurses with dyslexia.

Gillin, Nicola

2015-09-01

To discuss the legal, ethical and practical considerations in UK studies involving nurses with dyslexia and medication administration errors (MAEs). Nurses with dyslexia are a vulnerable population as they are susceptible to misrepresentation in research, especially that which involves a sensitive topic such as MAEs. Nurses with dyslexia may be particularly vulnerable to research that could exploit, implicate or attribute unsafe practice to them and their disability. Special consideration should be exercised when researching this population. Despite the potential for legal, ethical and practical issues, MAEs and nurses with dyslexia are under-researched areas and warrant further research. Benefits can be gained, not only by participants but also those with a vested interest in how best to support dyslexic nurses in clinical practice. Through effective design, risks can be identified and minimised, and the research made viable, ethically sound and ultimately beneficial to all those involved.

Background Medical professionalism has received increased worldwide attention, yet there is limited information on the applicability and utility of established Western professionalism frameworks in non-Western nations. Objective We developed a locally derived consensus definition of medical professionalism for the United Arab Emirates (UAE), which reflects the cultural and social constructs of the UAE and the Middle East. Methods We used a purposive sample of 14 physicians working in the UAE as clinical and education leaders. This expert panel used qualitative methods, including the world café, nominal group technique, the Delphi method, and an interpretive thematic analysis to develop the consensus statement. Results The expert panel defined 9 attributes of medical professionalism. There was considerable overlap with accepted Western definitions, along with important differences in 3 aspects: (1) the primacy of social justice and societal rights; (2) the role of the physician's personal faith and spirituality in guiding professional practices; and (3) societal expectations for professional attributes of physicians that extend beyond the practice of medicine. Conclusions Professionalism is a social construct influenced by cultural and religious contexts. It is imperative that definitions of professionalism used in the education of physicians in training and in the assessment of practicing physicians be formulated locally and encompass specific competencies relevant to the local, social, and cultural context for medical practice. Our goal was to develop a secular consensus statement that encompasses culture and values relevant to professionalism for the UAE and the Arab region.

The Microscale Synthesis and Electrochemistry of Low-Valent Mononuclear Complexes (h3-C3H5)Fe(CO)3 X (X = I, Br, Cl)

Mocellin, Enrico; Russell, Richard; Ravera, Mauro

1998-06-01

The experimental content of this paper will appeal to pedagogues and students who might be looking for new ideas that have an element of challenge. By combining experimental procedures which place microscale, chemical synthesis, and an inclusive, unified, product characterization in perspective, we have afforded the student the scope to obtain progressive, disciplined results and the opportunity to discuss these in the subsequent reporting. By this process, it is our experience that the students often identify with the practical work that is being undertaken, and they develop considerable empathy during their contribution to the "discovery" process that this laboratory program offers. The experimental work can be abbreviated to a single compound, subdivided into synthesis or electrochemistry, or extended to macroscale and other instrumental techniques of characterization, thus offering opportunities to accommodate time constraints, class results combination and discussion, and individual student enthusiasm. We believe that having to accept and/or constructively criticize sequential experimental results, collected by fellow students, mimics more realistically the practice of chemistry at the workplace and can build enthusiasm and elicit contagious fellowship from the class. All of these aspects can simply be achieved by utilizing the listed journals and references therein. Most importantly, it affords the students the opportunity to extricate themselves as innocent bystanders from the conventional "single experiment" practical laboratory to a path of practice and achievement in the scientific method.

The aim was to describe transfusion practice in critically ill patients at an international level and evaluate the effects of red blood cell (RBC) transfusion on outcomes in these patients. This was a pre-planned sub-study of the Intensive Care Over Nations audit, which involved 730 ICUs in 84 countries and included all adult patients admitted between 8 May and 18 May 2012, except admissions for routine postoperative surveillance. ICU and hospital outcomes were recorded. Among the 10,069 patients included in the audit, data related to transfusion had been completed for 9553 (mean age 60 ± 18 years, 60% male); 2511 (26.3%) of these had received a transfusion, with considerable variation among geographic regions. The mean lowest hemoglobin on the day of transfusion was 8.3 ± 1.7 g/dL, but varied from 7.8 ± 1.4 g/dL in the Middle East to 8.9 ± 1.9 g/dL in Eastern Europe. Hospital mortality rates were higher in transfused than in non-transfused patients (30.0% vs. 19.6%, p < 0.001) and increased with increasing numbers of transfused units. In an extended Cox proportional hazard analysis, the relative risk of in-hospital death was slightly lower after transfusion in the whole cohort (hazard ratio 0.98, confidence interval 0.96-1.00, p = 0.048). There was a stepwise decrease in the hazard ratio for mortality after transfusion with increasing admission severity scores. More than one fourth of critically ill patients are transfused during their ICU stay, with considerable variations in transfusion practice among geographic regions. After adjustment for confounders, RBC transfusions were associated with a slightly lower relative risk of in-hospital death, especially in the most severely ill patients, highlighting the importance of taking the severity of illness into account when making transfusion decisions.

Rehabilitation as "destination triage": a critical examination of discharge planning.

PubMed

Durocher, Evelyne; Gibson, Barbara E; Rappolt, Susan

2017-06-01

In this paper we examine how the intersection of various social and political influences shapes discharge planning and rehabilitation practices in ways that may not meet the espoused aims of rehabilitation programs or the preferences of older adults and their families. Taking a critical bioethics perspective, we used microethnographic case study methods to examine discharge-planning processes in a well-established older adult inpatient rehabilitation setting in Canada. The data included observations of discharge-planning family conferences and semi-structured interviews conducted with older adults facing discharge, their family members and rehabilitation professionals involved in discharge planning. From the time of admission, a contextual push to focus on discharge superseded program aims of providing interventions to increase older adults' functional capabilities. Professionals' primary commitment to safety limited consideration of discharge options and resulted in costly and potentially unnecessary recommendations for 24-hour care. The resulting "rehabilitation" stay was more akin to an extended process of "destination triage" biased towards the promotion of physical safety than optimizing functioning. The resulting reduction of rehabilitation into "destination triage" has significant social, financial and occupational implications for older adults and their families, and broader implications for healthcare services and overarching healthcare systems. Implications for Rehabilitation Current trends promoting consideration of discharge planning from the point of admission and prioritizing physical safety are shifting the focus of rehabilitation away from interventions to maximize recovery of function, which are the stated aims of rehabilitation. Such practices furthermore promote assessments to determine prognosis early in the rehabilitation stay when accurate prognosis is difficult, which can lead to overly conservative recommendations for discharge from rehabilitation services, thus further negating the impact of rehabilitation. Further work is required to examine the social, occupational and functional implications of superseding rehabilitation interventions to maximize capabilities with practices that prioritize safety over quality of life for older adults and their family members.

Feasibility and Effectiveness of Parent-Child Interaction Therapy with Victims of Domestic Violence: A Pilot Study

2016-01-01

Parent-Child Interaction Therapy (PCIT) is an evidence-based treatment for young children (aged 2.5 to 7 years) with externalizing behavior problems. Since its development, PCIT has been applied to a wide array of childhood problems and has a significant evidence base for families with histories of child physical abuse. The current study extended the existing literature by testing the effectiveness and feasibility of PCIT in an urban domestic violence shelter with community-based clinicians delivering the treatment. Seven clinicians implemented PCIT with parent-child dyads which included 21 preschool (M = 4.57 years; SD = 1.50) children. Families completed assessments at baseline, mid-treatment, and post-treatment. Nine families completed PCIT (43%). Completion of PCIT was associated with improved child behavior, parenting practices, and mental health symptoms. Considerations for treatment delivery and future directions are discussed.

2010-01-01

Abstract Vector-mediated cardiac gene therapy holds tremendous promise as a translatable platform technology for treating many cardiovascular diseases. The ideal technique is one that is efficient and practical, allowing for global cardiac gene expression, while minimizing collateral expression in other organs. Here we survey the available in vivo vector-mediated cardiac gene delivery methods—including transcutaneous, intravascular, intramuscular, and cardiopulmonary bypass techniques—with consideration of the relative merits and deficiencies of each. Review of available techniques suggests that an optimal method for vector-mediated gene delivery to the large animal myocardium would ideally employ retrograde and/or anterograde transcoronary gene delivery,extended vector residence time in the coronary circulation, an increased myocardial transcapillary gradient using physical methods, increased endothelial permeability with pharmacological agents, minimal collateral gene expression by isolation of the cardiac circulation from the systemic, and have low immunogenicity.

Rasmussen's legacy: A paradigm change in engineering for safety.

PubMed

Leveson, Nancy G

2017-03-01

This paper describes three applications of Rasmussen's idea to systems engineering practice. The first is the application of the abstraction hierarchy to engineering specifications, particularly requirements specification. The second is the use of Rasmussen's ideas in safety modeling and analysis to create a new, more powerful type of accident causation model that extends traditional models to better handle human-operated, software-intensive, sociotechnical systems. Because this new model has a formal, mathematical foundation built on systems theory (as was Rasmussen's original model), new modeling and analysis tools become possible. The third application is to engineering hazard analysis. Engineers have traditionally either omitted human from consideration in system hazard analysis or have treated them rather superficially, for example, that they behave randomly. Applying Rasmussen's model of human error to a powerful new hazard analysis technique allows human behavior to be included in engineering hazard analysis. Copyright © 2016 Elsevier Ltd.

Radar altimeter waveform modeled parameter recovery. [SEASAT-1 data

NASA Technical Reports Server (NTRS)

1981-01-01

Satellite-borne radar altimeters include waveform sampling gates providing point samples of the transmitted radar pulse after its scattering from the ocean's surface. Averages of the waveform sampler data can be fitted by varying parameters in a model mean return waveform. The theoretical waveform model used is described as well as a general iterative nonlinear least squares procedures used to obtain estimates of parameters characterizing the modeled waveform for SEASAT-1 data. The six waveform parameters recovered by the fitting procedure are: (1) amplitude; (2) time origin, or track point; (3) ocean surface rms roughness; (4) noise baseline; (5) ocean surface skewness; and (6) altitude or off-nadir angle. Additional practical processing considerations are addressed and FORTRAN source listing for subroutines used in the waveform fitting are included. While the description is for the Seasat-1 altimeter waveform data analysis, the work can easily be generalized and extended to other radar altimeter systems.

The German school system is socially highly unequal, as educational research criticized for a long time. While in some schools socially privileged pupils are the majority, other schools are composed by mostly poor pupils. The combination of socio-geographic and educational geographic considerations leads to a social school index, which clearly shows how strong schools are socially privileged or disadvantaged. The paper presents a practical example of building a social school index for cities and compares the results. The residence-based density index on grid data from German Social Code (book 2) is preferred because it is unproblematic in terms of data protection law and can be extended at the level of 100 × 100 m grids. Calculating detailed and differentiated social school indices with school enrollment data leads to very good results, but is much more work.

Oman contains diverse and abundant reef coral communities that extend along a coast that borders three environmentally distinct water bodies, with corals existing under unique and often stressful environmental conditions. In recent years Oman's reefs have undergone considerable change due to recurrent predatory starfish outbreaks, cyclone damage, harmful algal blooms, and other stressors. In this review we summarize current knowledge of the biology and status of corals in Oman, particularly in light of recent stressors and projected future threats, and examine current reef management practices. Oman's coral communities occur in marginal environmental conditions for reefs, and hence are quite vulnerable to anthropogenic effects. We recommend a focus on developing conservation-oriented coral research to guide proactive management and expansion of the number and size of designated protected areas in Oman, particularly those associated with critical coral habitat.

Ethnography of epidemiologic transition: Avian flu, global health politics and agro-industrial capitalism in Thailand.

PubMed

Chuengsatiansup, Komatra

2008-04-01

This paper situates the ethnography of avian flu within the geo-political context of a new epidemiologic transition. Drawing on anthropological experience and insight, this paper examines areas of enquiry in which an ethnographic approach could contribute to a better implementation of prevention and control measures. Within the context of newly emerging diseases and accelerated globalization, the task of ethnography needs to extend far beyond the local. This paper reveals two major global issues that the ethnography of epidemiologic transition must take into consideration: (1) Global agro-industrial capitalism, and (2) global politics in the context of international health organizations and multi-national drug companies. The case of Thailand poses a question of how the strength of ethnographic practice could be deployed to account for the reality of the global-local interface of the new epidemiologic transition.

Recent developments in analysis of crack propagation and fracture of practical materials

Present U.S. Air Force and proposed U.S. civil airworthiness regulations are based on considerations of 'damage tolerance' in aircraft structures. Airworthiness is assured by demonstrating that damage that escapes one in a sequence of periodic inspections will not grow to critical size before the next inspection. The evaluations conducted employ fracture mechanics analyses. Problems arise because the features of fracture mechanics applications related to aircraft structures are more complex than the cases of fracture mechanics which have been mainly investigated. NASA has, therefore, conducted a variety of research tasks to extend the capabilities of fracture mechanics to deal with some of these complexities. The current stage of development of these capabilities is described. Attention is given to the limitations of linear elastic fracture mechanics, a two-parameter fracture criterion, aspects of fatigue crack propagation, and crack propagation and fracture in built-up structures.

Music therapy research in the NICU: an updated meta-analysis.

Standley, Jayne

2012-01-01

To provide an overview of developmental and medical benefits of music therapy for preterm infants. Meta-analysis. Empirical music studies with preterm infants in the neonatal intensive care unit (NICU). Evidence-based NICU music therapy (NICU -MT ) was highly beneficial with an overall large significant effect size (Cohen's d = 0.82). Effects because of music were consistently in a positive direction. Results of the current analysis replicated findings of a prior meta-analysis and included extended use of music.(1) Benefits were greatest for live music therapy (MT ) and for use early in the infant's NICU stay (birth weight <1,000 g, birth postmenstrual age <28 weeks). Results justify strong consideration for the inclusion of the following evidence-based NICU -MT protocols in best practice standards for NICU treatment of preterm infants: music listening for pacification, music reinforcement of sucking, and music pacification as the basis for multilayered, multimodal stimulation.

Semi-active suspension for automotive application

NASA Astrophysics Data System (ADS)

Venhovens, Paul J. T.; Devlugt, Alex R.

The theoretical considerations for semi-active damping system evaluation, with respect to semi-active suspension and Kalman filtering, are discussed in terms of the software. Some prototype hardware developments are proposed. A significant improvement in ride comfort performance can be obtained, indicated by root mean square body acceleration values and frequency responses, using a switchable damper system with two settings. Nevertheless the improvement is accompanied by an increase in dynamic tire load variations. The main benefit of semi-active suspensions is the potential of changing the low frequency section of the transfer function. In practice this will support the impression of extra driving stability. It is advisable to apply an adaptive control strategy like the (extended) skyhook version switching more to the 'comfort' setting for straight (and smooth/moderate roughness) road running and switching to 'road holding' for handling maneuvers and possibly rough roads and discrete, severe events like potholes.

Using alternatives to face-to-face consultations: a survey of prevalence and attitudes in general practice

PubMed Central

Brant, Heather; Atherton, Helen; Ziebland, Sue; McKinstry, Brian; Campbell, John L; Salisbury, Chris

2016-01-01

Background The ubiquitous use of communication technologies has led to an expectation that a similar approach should extend to health care. Despite considerable rhetoric about the need for general practices to offer alternatives to face-to-face consultations, such as telephone, email, and internet video consultations, the extent to which such technologies are actually used at present is unclear. Aim The aim of the survey was to identify the frequency and range of ways in which general practices are providing (or planning) alternatives to face-to-face consultations. Design and setting A postal survey of practices around Bristol, Oxford, Lothian, the Highlands, and the Western Isles of Scotland. Method A postal questionnaire survey was sent to each of the GPs and practice managers of 421 practices between January and May 2015. Results A response was received from 319/421 practices (76%). Although the majority of the practices reported that they were conducting telephone consultations frequently (n = 211/318, 66%), fewer were implementing email consultations (n = 18/318, 6%), and most (n = 169/318, 53%) had no plans to introduce this. None were currently using internet video, and 86% (n = 273/318) had no plans to introduce internet video consultations. These findings were repeated in the reported use of alternatives to face-to-face consultations at an individual GP level. Optional free text responses were completed by 28% of responders, and offered an explanation for the (often perceived) barriers and incentives for implementation. Conclusion Despite policy pressure to introduce consultations by email and internet video, there is a general reluctance among GPs to implement alternatives to face-to-face consultations. This identifies a substantial gap between rhetoric and reality in terms of the likelihood of certain alternatives (email, video) changing practice in the near future. PMID:27215571

Calls for embracing the potential and responsibility of occupational therapy to address socio-political conditions that perpetuate occupational injustices have materialized in the literature. However, to reach beyond traditional frameworks informing practices, this social agenda requires the incorporation of diverse epistemological and methodological approaches to support action commensurate with social transformative goals. Our intent is to present a methodological approach that can help extend the ways of thinking or frameworks used in occupational therapy and science to support the ongoing development of practices with and for individuals and collectives affected by marginalizing conditions. We describe the epistemological and theoretical underpinnings of a methodological approach drawing on Freire and Bakhtin's work. Integrating our shared experience taking part in an example study, we discuss the unique advantages of co-generating data using two methods aligned with this approach; dialogical interviews and critical reflexivity. Key considerations when employing this approach are presented, based on its proposed epistemological and theoretical stance and our shared experiences engaging in it. A critical dialogical approach offers one way forward in expanding occupational therapy and science scholarship by promoting collaborative knowledge generation and examination of taken-for-granted understandings that shape individuals assumptions and actions.

Electron microscopy and forensic practice

Kotrlý, Marek; Turková, Ivana

2013-05-01

Electron microanalysis in forensic practice ranks among basic applications used in investigation of traces (latents, stains, etc.) from crime scenes. Applying electron microscope allows for rapid screening and receiving initial information for a wide range of traces. SEM with EDS/WDS makes it possible to observe topography surface and morphology samples and examination of chemical components. Physical laboratory of the Institute of Criminalistics Prague use SEM especially for examination of inorganic samples, rarely for biology and other material. Recently, possibilities of electron microscopy have been extended considerably using dual systems with focused ion beam. These systems are applied mainly in study of inner micro and nanoparticles , thin layers (intersecting lines in graphical forensic examinations, analysis of layers of functional glass, etc.), study of alloys microdefects, creating 3D particles and aggregates models, etc. Automated mineralogical analyses are a great asset to analysis of mineral phases, particularly soils, similarly it holds for cathode luminescence, predominantly colour one and precise quantitative measurement of their spectral characteristics. Among latest innovations that are becoming to appear also at ordinary laboratories are TOF - SIMS systems and micro Raman spectroscopy with a resolution comparable to EDS/WDS analysis (capable of achieving similar level as through EDS/WDS analysis).

Dressing disrupted: negotiating care through the materiality of dress in the context of dementia.

PubMed

Buse, Christina; Twigg, Julia

2018-02-01

This paper explores how the materiality of dress mediates and shapes practices of care in the context of dementia. Earlier research called for an approach to conceptualising care that recognised the role played by everyday artefacts. We extend this to a consideration of dress and dressing the body in relation to people with dementia that involves the direct manipulation of material objects, as well as the materiality of bodies. The paper draws on an ESRC funded study Dementia and Dress, which examined experiences of dress for people with dementia, families and care-workers using ethnographic and qualitative methods. Our analysis explores the process of dressing the body, the physicality of guiding and manipulating bodies into clothing, dealing with fabrics and bodies which 'act back' and are resistant to the process of dressing. We consider how the materiality of clothing can constrain or enable practices of care, exploring tensions between garments that support ease of dressing and those that sustain identity. Examining negotiations around dress also reveals tensions between competing 'logics' of care (Mol ). © 2018 The Authors.

2016-01-01

During last 20 years, neuroimaging with functional magnetic resonance imaging (fMRI) in people with drug addictions has introduced a wide range of quantitative biomarkers from brain's regional or network level activities during different cognitive functions. These quantitative biomarkers could be potentially used for assessment, planning, prediction, and monitoring for "addiction medicine" during screening, acute intoxication, admission to a program, completion of an acute program, admission to a long-term program, and postgraduation follow-up. In this chapter, we have briefly reviewed main neurocognitive targets for fMRI studies associated with addictive behaviors, main study types using fMRI among drug dependents, and potential applications for fMRI in addiction medicine. Main challenges and limitations for extending fMRI studies and evidences aiming at clinical applications in addiction medicine are also discussed. There is still a significant gap between available evidences from group-based fMRI studies and personalized decisions during daily practices in addiction medicine. It will be important to fill this gap with large-scale clinical trials and longitudinal studies using fMRI measures with a well-defined strategic plan for the future. © 2016 Elsevier B.V.

[Clinical autopsies. Practical approach, legal foundations and ethical considerations].

Friemann, J

2010-07-01

Only an autopsy can demonstrate topographical and morphological circumstances in detail and correlate the clinical and autopsy findings based on the examination of all organs. The practical approach in a fatality is described based on the example of the Lüdenscheid Hospital. A uniform legal regulation for dealing with corpses does not exist in Germany. There are two approaches to the question under which circumstances a clinical autopsy is allowed: the extended permission solution and the objection solution. Whether a clinical autopsy can be carried out is decided by the medical specialist selected on application. Autopsies can be necessary from insurance or administrative legal grounds or in the case of an anatomical autopsy is decided by the persons themselves. In order to guarantee the quality of an autopsy it is necessary to use a standardized approach with evaluation and assessment of the results, for example using a quality assurance protocol and the production of an autopsy report. Using this approach important information can be gained not only on the accuracy of the main diagnosis and cause of death but also on additional diseases, response to therapy and the course of the disease and under circumstances can lead to modifications in the approach.

The role of traditional healers in the provision of health care and family planning services: Malay traditional and indigenous medicine.

Raden Sanusi, H R; Werner, R

1985-01-01

The practitioners of traditional and indigenous medicine rely mainly upon medicinal plants and herbs for the preparation of therapeutic substances. The therapeutic properties of several medicinal plants and popular traditional medicine remedies are being investigated and validated. Present health care systems place people from developing countries in a dilemma. Countries can either continue providing a type of health care which cannot be extended to all in need or rethink and offer more inclusive types of medical care and delivery systems. Traditional medicine has a clear role to play in society, and even the World Health Organization supports the practice of traditional medicine to complement modern medicine. Traditional Malay medicine is the distillation of vast historical experience dating back more than 1000 years. It is often based upon observation, clinical trials, and experiments. The promotion and development of Malay traditional medicine can both foster dignity and self-confidence in communities through self-reliance, while considerably reducing the country's drug costs. The integrity and dignity of a people stems from self-respect and self-reliance. The practice of traditional medicine practitioners can help promote such conditions in many ways. It serves as an important focus for international technical cooperation and offers the potential for major breakthroughs in therapeutics and health care delivery. Effort should be taken to keep the practice of traditional medicine alive in Malaysia.

Using technology within the treatment of eating disorders: a clinical practice review.

Shingleton, Rebecca M; Richards, Lauren K; Thompson-Brenner, Heather

2013-12-01

The focus of this clinical practice review is to provide clinicians a framework for incorporating technology into the treatment of eating disorders (EDs). We detailed studies that were published within the past 11 years (2002-2012) and that included at least 10 participants. Our primary aims were to describe how technology has been used to enhance the delivery of ED treatment as well as report the effectiveness of these technology-based interventions. We also provided clinical applications and considerations for clinicians who wish to use technology within their own practice. We found that a range of technologies (e.g., televideo, e-mail, CD-ROM, Internet, text message) have been used as a means to either deliver or enhance treatment at various levels of care (e.g., therapy, guided self-help, treatment adjunct). The majority of the studies were based on cognitive-behavioral principles and included samples diagnosed with bulimia nervosa (BN), binge eating disorder (BED), or subclinical levels of BN or BED. Most researchers reported positive results, with a few caveats such as technology-based interventions may not be optimal for individuals with more severe pathology, and some individuals described wanting more personal interaction. The overarching finding was that technology may be successfully integrated within ED treatment and may offer new ways to extend ED interventions to individuals who may not otherwise have access to specialty ED care.

Human papillomaviruses (HPVs) are the necessary cause of most cervical cancers, a large proportion of other anogenital cancers, and a subset of oropharyngeal cancers. The knowledge about HPV has led to development of novel HPV-based prevention strategies with important impact on clinical and public health practice. Two complementary reviews have been prepared following the 2015 Eurogin Conference to evaluate how knowledge about HPV is changing practice in HPV infection and disease control through vaccination and screening. This review focuses on screening for cervical and anal cancers in increasingly vaccinated populations. The introduction of HPV vaccines a decade ago has led to reductions in HPV infections and early cancer precursors in countries with wide vaccination coverage. Despite the high efficacy of HPV vaccines, cervical cancer screening will remain important for many decades. Many healthcare systems are considering switching to primary HPV screening, which has higher sensitivity for cervical precancers and allows extending screening intervals. We describe different approaches to implementing HPV-based screening efforts in different healthcare systems with a focus in high-income countries. While the population prevalence for other anogenital cancers is too low for population-based screening, anal cancer incidence is very high in HIV-infected men who have sex with men, warranting consideration of early detection approaches. We summarize the current evidence on HPV-based prevention of anal cancers and highlight important evidence gaps. © 2016 UICC.

Adverse outcome pathway (AOP) development and evaluation ...

EPA Pesticide Factsheets

The Adverse Outcome Pathway provides a construct for assembling mechanistic information at different levels of biological organization in a form designed to support regulatory decision making. In particular, it frames the link between molecular and cellular events that can be measured in high throughput toxicity testing and the organism or population-level events that are commonly relevant in defining risk. Recognizing the importance of this emerging framework, the Organisation for Economic Co-operation and Development (OECD) launched a program to support the development, documentation and consideration of AOPs by the international community in 2012 (http://www.oecd.org/chemicalsafety/testing/adverse-outcome-pathways-molecular-screening-and-toxicogenomics.htm). In 2014, a handbook (https://aopkb.org/common/AOP_Handbook.pdf) was developed to guide users in the documentation and evaluation of AOPs and their entry into an official knowledgebase. The handbook draws on longstanding experience in consideration of mechanistic data (e.g., mode of action analysis) to inform risk assessment. To further assist users, a training program was developed by members of the OECD Extended Advisory Group to teach users the basic principles of AOP development and the best practices as outlined in the OECD AOP handbook. Training sessions began in early 2015, and this course will provide training for interested SOT scientists. Following this course, all participants will be familiar w

The state of animal welfare in the context of refinement.

PubMed

Zurlo, Joanne; Hutchinson, Eric

2014-01-01

The ultimate goal of the Three Rs is the full replacement of animals used in biomedical research and testing. However, replacement is unlikely to occur in the near future; therefore the scientific community as a whole must continue to devote considerable effort to ensure optimal animal welfare for the benefit of the science and the animals, i.e., the R of refinement. Laws governing the care and use of laboratory animals have recently been revised in Europe and the US and these place greater emphasis on promoting the well-being of the animals in addition to minimizing pain and distress. Social housing for social species is now the default condition, which can present a challenge in certain experimental settings and for certain species. The practice of positive reinforcement training of laboratory animals, particularly non-human primates, is gathering momentum but is not yet universally employed. Enhanced consideration of refinement extends to rodents, particularly mice, whose use is still increasing as more genetically modified models are generated. The wastage of extraneous mice and the method of their euthanasia are refinement issues that still need to be addressed. An international, concerted effort into defining the needs of laboratory animals is still necessary to improve the quality of the animal models used as well as their welfare.

Ergonomics action research I: shifting from hypothesis testing to experiential learning.

PubMed

Neumann, W P; Dixon, S M; Ekman, M

2012-01-01

This paper presents the case for the need for 'Action Research' (AR) approaches to gain understanding of how ergonomics considerations can best be integrated into the design of new work systems. The AR researchers work collaboratively with other stakeholders to solve a real-world problem: gaining insight into the problem and factors influencing solution building from an embedded position in the development process. This experience is interpreted in terms of available theory and can support further theory development. This non-experimental approach can help provide practical new approaches for integrating ergonomics considerations into real work system design processes. The AR approach suffers from a lack of acceptance by conventionally trained scientists. This paper aims to help overcome this weakness by developing the underlying theory and rationale for using AR approaches in ergonomics research. We propose further development of hybrid approaches which incorporate other evaluation techniques to extend the knowledge gains from AR projects. Researchers should engage directly with organisations in ergonomics projects so that they can better understand the challenges and needs of practitioners who are trying to apply available scientific knowledge in their own unique context. Such 'Action Research' could help develop theory and approaches useful to improve mobilisation and application of ergonomics knowledge in organisations.

Making working memory work: the effects of extended practice on focus capacity and the processes of updating, forward access, and random access.

Price, John M; Colflesh, Gregory J H; Cerella, John; Verhaeghen, Paul

2014-05-01

We investigated the effects of 10h of practice on variations of the N-Back task to investigate the processes underlying possible expansion of the focus of attention within working memory. Using subtractive logic, we showed that random access (i.e., Sternberg-like search) yielded a modest effect (a 50% increase in speed) whereas the processes of forward access (i.e., retrieval in order, as in a standard N-Back task) and updating (i.e., changing the contents of working memory) were executed about 5 times faster after extended practice. We additionally found that extended practice increased working memory capacity as measured by the size of the focus of attention for the forward-access task, but not for variations where probing was in random order. This suggests that working memory capacity may depend on the type of search process engaged, and that certain working-memory-related cognitive processes are more amenable to practice than others.

The best donors for hematopoietic SCT (HSCT) are fully-matched siblings. In patients without fully-matched siblings, HLA registries or cord blood banks are alternative strategies with some restrictions. Owing to the high rate of consanguineous marriage in our country, between 2006 and 2013, extended family searches were undertaken in Hematology-Oncology Research Center and Stem Cell Transplantation (HORCSCT), Tehran, Iran, in 523 HSCT candidates with parental consanguinity and no available HLA identical sibling. Fully-matched other-relative donors were found for 109 cases. We retrospectively studied the HSCT outcome in these patients. Median time to neutrophil engraftment was 13 days (range: 9-31days). In 83 patients, full chimerism and in 17 patients, mixed chimerism was achieved. Acute GvHD (aGvHD) grade II-IV appeared in 36 patients (33%). The frequency of aGvHD development in various familial subgroups was NS. Five patients expired before day+100. In the surviving 104 cases, chronic GvHD developed in 20 patients (19.2%). The distantly related subgroup had significantly a higher rate of cGvHD (P=0.04). The 2-year OS and disease-free survival (DFS) were 76.7±4.5% and 71.7±4.7%, respectively. No significant difference in OS (P=0.30) and DFS (P=0.80) was unraveled between various familial relationships. Our considerable rate of fully-matched non-sibling family members and the favorable outcome support the rationale for extended family search in regions where consanguineous marriage is widely practiced.

To determine a) if a checklist covering a diverse group of intensive care unit protocols and objectives would improve clinician consideration of these domains and b) if improved consideration would change practice patterns. Pre- and post observational study. A 24-bed surgical/burn/trauma intensive care unit in a teaching hospital. A total of 1399 patients admitted between June 2006 and May 2007. The first component of the study evaluated whether mandating verbal review of a checklist covering 14 intensive care unit best practices altered verbal consideration of these domains. Evaluation was performed using real-time bedside audits on morning rounds. The second component evaluated whether the checklist altered implementation of these domains by changing practice patterns. Evaluation was performed by analyzing data from the Project IMPACT database after patients left the intensive care unit. Verbal consideration of evaluable domains improved from 90.9% (530/583) to 99.7% (669/671, p < .0001) after verbal review of the checklist was mandated. Bedside consideration improved on the use of deep venous thrombosis prophylaxis (p < .05), stress ulcer prophylaxis (p < .01), oral care for ventilated patients (p < 0.01), electrolyte repletion (p < .01), initiation of physical therapy (p < .05), and documentation of restraint orders (p < .0001). Mandatory verbal review of the checklist resulted in a greater than two-fold increase in transferring patients out of the intensive care unit on telemetry (16% vs. 35%, p < .0001) and initiation of physical therapy (28% vs. 42%, p < .0001) compared with baseline practice. A mandatory verbal review of a checklist covering a wide range of objectives and goals at each patient's bedside is an effective method to improve both consideration and implementation of intensive care unit best practices. A bedside checklist is a simple, cost-effective method to prevent errors of omission in basic domains of intensive care unit management that might otherwise be forgotten in the setting of more urgent care requirements.

Clinical practice guidelines. To develop the first Canadian clinical practice guidelines for screening and diagnosis of neuropathic pain in people with spinal cord injury (SCI). The guidelines are relevant for inpatient and outpatient SCI rehabilitation settings in Canada. The CanPainSCI Working Group reviewed evidence to address clinical questions regarding screening and diagnosis of neuropathic pain after SCI. A consensus process was followed to achieve agreement on recommendations and clinical considerations. Twelve recommendations, based on expert consensus, were developed for the screening and diagnosis of neuropathic pain after SCI. The recommendations address methods for assessment, documentation tools, team member accountability, frequency of screening and considerations for diagnostic investigation. Important clinical considerations accompany each recommendation. The expert Working Group developed recommendations for the screening and diagnosis of neuropathic pain after SCI that should be used to inform practice.

Extending the scope of practice of allied health professionals has been a strategy adopted in the United Kingdom to address issues within the health system. Australia's health system is currently undermined by similar issues, heightening government interest in adopting the extended scope health care model. The aim of the current study was to describe the activities and outcomes of a dietitian-led gastroenterology clinic which operated under an extended scope of practice model in an outpatient gastroenterology department at a tertiary hospital in regional Queensland, Australia, and to assess patient satisfaction with the initiative. A descriptive, cross-sectional case series undertaken over 50 clinics involving 82 category 2 and 3 patients with suspected/confirmed coeliac disease or inflammatory bowel disease; low haemoglobin; gastroesophageal reflux disease, or; malnutrition. Data was analysed using Microsoft Excel 2010, and presented as descriptive statistics. Sixty out of 82 selected patients (median age 51 years) attended an initial appointment with the dietitian. Twenty-four review appointments were attended. Average waiting period for an initial appointment was 148 days (range 31-308 days). A total of 149 management strategies were provided, and 94 (63 %) of these involved the dietitian utilising extended scope of practice. The dietitian managed 47 (78 %) patients without need for gastroenterologist referral, and 25 (42 %) were discharged after dietetic management. Patients reported high levels of satisfaction with the clinic. Seventy-eight percent of category 2 and 3 patients referred to the gastroenterologist could be managed exclusively in the dietitian-led clinic. This extended scope model of care could potentially benefit the efficiency and acceptability of Australia's public health system.

Demographic change and recruitment problems in family practice are increasingly threatening an adequate primary care workforce in many countries. Thus, it is important to attract young physicians to the field. The purpose of the present study was to examine the effect of an early community-based 28-h family practice elective with one-to-one mentoring on medical students' consideration of family practice as a career option, their interest in working office-based, and several perceptions with regard to specific aspects of a family physician's work. First- and second-year medical students completed questionnaires before and after a short community-based family practice elective, consisting of a preparatory course and a community-based practical experience with one-to-one mentoring by trained family physicians. We found a significantly higher rate of students favoring family practice as a career option after the elective (32.7% vs. 26.0%, p = 0.039). Furthermore, the ranking of family practice among other considered career options improved (p = 0.002). Considerations to work office-based in the future did not change significantly. Perceptions regarding a family physician's job changed positively with regard to the possibility of long-term doctor-patient relationships and treatment of complex disease patterns. The majority of the students described identification with the respective family physician tutor as a professional role model and an increased interest in the specialty. Our results indicate that a short community-based family practice elective early in medical education may positively influence medical students' considerations of a career in family practice. Furthermore, perceptions regarding the specialty with significant impact on its attractiveness may be positively adjusted. Further research is needed to evaluate the influence of different components of a family practice curriculum on the de facto career decisions of young physicians after graduation.

Ethical considerations for planetary protection in space exploration: a workshop.

2012-11-01

With the recognition of an increasing potential for discovery of extraterrestrial life, a diverse set of researchers have noted a need to examine the foundational ethical principles that should frame our collective space activities as we explore outer space. A COSPAR Workshop on Ethical Considerations for Planetary Protection in Space Exploration was convened at Princeton University on June 8-10, 2010, to examine whether planetary protection measures and practices should be extended to protect planetary environments within an ethical framework that goes beyond "science protection" per se. The workshop had been in development prior to a 2006 NRC report on preventing the forward contamination of Mars, although it responded directly to one of the recommendations of that report and to several peer-reviewed papers as well. The workshop focused on the implications and responsibilities engendered when exploring outer space while avoiding harmful impacts on planetary bodies. Over 3 days, workshop participants developed a set of recommendations addressing the need for a revised policy framework to address "harmful contamination" beyond biological contamination, noting that it is important to maintain the current COSPAR planetary protection policy for scientific exploration and activities. The attendees agreed that there is need for further study of the ethical considerations used on Earth and the examination of management options and governmental mechanisms useful for establishing an environmental stewardship framework that incorporates both scientific input and enforcement. Scientists need to undertake public dialogue to communicate widely about these future policy deliberations and to ensure public involvement in decision making. A number of incremental steps have been taken since the workshop to implement some of these recommendations.

to explore midwives' attitudes and perceptions about extending their role to the examination of the newborn baby, as well as their general perceptions and attitudes to new role developments. qualitative, data collected using semi-structured interviews, which were exploratory and interactive in form. six maternity hospitals in South-east England. ten midwives were purposefully selected, including five trained in the examination of the newborn baby and currently conducting examinations and five who had not. Most of the midwives had been qualified for over ten years and had a wide range of clinical experience in hospital and community settings. midwives identified many benefits to themselves, to their profession and to the mothers as a result of developing their role into the examination of the newborn baby. The major benefit cited was improved job satisfaction, which was directly related to their ability to give continuity and total care to mothers and babies. Midwives also perceived that undertaking the examination strengthened their position as autonomous practitioners, by enabling them to provide total care to mothers and babies who fitted their criteria of normality. Moreover, midwives thought that improvements in the overall quality of care to mothers would result from them performing the examination, including improved communication, greater continuity of care and a more holistic examination. Although midwives were concerned about possible increase in workloads and pressure to take on new roles, the examination was generally perceived as being easily incorporated into their current practice without compromising overall standards in midwifery care. Midwives expressed concern about 'extending' practice into areas that did not fit their perceptions of normality and about being 'pressurised' into taking on new roles. it would appear from this study that an important consideration for midwives in their acceptance of new roles, is the relationship of that role to their position as experts in normality. Midwives in this study viewed the examination of the newborn baby as 'fitting in' with their perceptions of the core values of midwifery.

Despite several clinical practice guidelines, there remains a considerable gap in prevention and management of obesity in primary care. To address the need for changing provider behaviour, a randomized controlled trial with convergent mixed method evaluation, the 5As Team (5AsT) study, was conducted. As part of the 5AsT intervention, the 5AsT tool kit was developed. This paper describes the development process and evaluation of these tools. Tools were co-developed by the multidisciplinary research team and the 5AsT, which included registered nurses/nurse practitioners (n = 15), mental health workers (n = 7) and registered dieticians (n = 7), who were previously randomized to the 5AsT intervention group at a primary care network in Edmonton, Alberta, Canada. The 5AsT tool development occurred through a practice/implementation-oriented, need-based, iterative process during learning collaborative sessions of the 5AsT intervention. Feedback during tool development was received through field notes and final provider evaluation was carried out through anonymous questionnaires. Twelve tools were co-developed with 5AsT. All tools were evaluated as either 'most useful' or 'moderately useful' in primary care practice by the 5AsT. Four key findings during 5AsT tool development were the need for: tools that were adaptive, tools to facilitate interdisciplinary practice, tools to help patients understand realistic expectations for weight loss and shared decision-making tools for goal setting and relapse prevention. The 5AsT tools are primary care tools which extend the utility of the 5As of obesity management framework in clinical practice. © 2015 The Authors.

Nurses are able to prescribe independently from a list of nearly 250 prescription only medicines for a range of over 100 medical conditions or, from the whole British National Formulary as a supplementary prescriber. There is some evidence available on the prescribing practices of district nurses and health visitors and early independent extended prescribers. Little or no attention has focussed on supplementary nurse prescribing. To provide an overview of the prescribing practices of independent extended/supplementary nurse prescribers and the factors that facilitate or inhibit prescribing. National questionnaire survey. United Kingdom. A convenience sample of 868 qualified independent extended/supplementary nurse prescribers self-completed a written questionnaire. A total of 756 (87%) used independent extended prescribing; 304 (35%) used supplementary prescribing to treat a range of chronic conditions (including asthma, diabetes and hypertension); 710 (82%) nurses worked in primary care. Nurses in general practice reported the largest number of reasons preventing prescribing. Reasons included the inability to computer generate prescriptions and to implement the Clinical Management Plan. Nurses in primary care reported more continuing professional development needs. These needs included update on prescribing policy and the treatment management of conditions. A total of 277 (32%) nurses were unable to access continuing professional development. Independent extended/supplementary nurse prescribers work predominantly in primary care and do prescribe medicines. These nurses are highly qualified and have many years clinical experience. Supplementary prescribing is used by a minority of nurses. Implementing the Clinical Management Plan is a barrier preventing the use of this mode of prescribing. The continuing professional development needs of independent extended/supplementary nurse prescribers are frequently unmet. It will become increasingly important that these needs are met once nurses are able to prescribe the full range of medicines included in the British National Formulary, limited only by their area of competence.

In discourse: Bourdieu's theory of practice and habitus in the context of a communication-oriented nursing interaction model.

PubMed

Sieger, Margot; Fritz, Elfriede; Them, Christa

2012-02-01

This paper presents a discussion on the potential of the theories of practice and habitus as espoused by the sociologist Bourdieu. The interaction between nurses and patients is a constitutive element in the nursing process and a central aspect in the theories developed by Paterson and Zderad, and Orlando. Bourdieu's theory of habitus and practices assists in understanding and explaining differentiated results concerning nurse-patient interaction. In a study on interactions with paraplegic patients, distinguished levels of interactions, which show considerable diversity among one another, could be identified. The data were collected over a period of 20 months in 2004-2006. The results present the central topics of interaction and show that understanding-oriented interaction is rare. Communicative acting in nursing always takes place in a social context. In the interaction with patients, nurses assign a higher distinctive value to the standardized concepts of care facilities than to the actually perceived need of care. An understanding-oriented interaction assumes that the nurses with their own contributions, themes and authorities, prove themselves in the eyes of the patient. It is expected from nurses that they habitualize their own concepts so that they can be represented in a convincing manner. If an understanding-oriented interaction is to extend into the practice of nursing, it is of crucial importance that both interaction partners assure each other how and with what capital their interaction is to be realized. Nurses need professional habitus to become agents in the social field of health. © 2011 Blackwell Publishing Ltd.

Custom, contract, and kidney exchange.

PubMed

Healy, Kieran; Krawiec, Kimberly D

2012-01-01

In this Essay, we examine a case in which the organizational and logistical demands of a novel form of organ exchange (the nonsimultaneous, extended, altruistic donor (NEAD) chain) do not map cleanly onto standard cultural schemas for either market or gift exchange, resulting in sociological ambiguity and legal uncertainty. In some ways, a NEAD chain resembles a form of generalized exchange, an ancient and widespread instance of the norm of reciprocity that can be thought of simply as the obligation to “pay it forward” rather than the obligation to reciprocate directly with the original giver. At the same time, a NEAD chain resembles a string of promises and commitments to deliver something in exchange for some valuable consideration--that is, a series of contracts. Neither of these salient "social imaginaries" of exchange--gift giving or formal contract--perfectly meets the practical demands of the NEAD system. As a result, neither contract nor generalized exchange drives the practice of NEAD chains. Rather, the majority of actual exchanges still resemble a simpler form of exchange: direct, simultaneous exchange between parties with no time delay or opportunity to back out. If NEAD chains are to reach their full promise for large-scale, nonsimultaneous organ transfer, legal uncertainties and sociological ambiguities must be finessed, both in the practices of the coordinating agencies and in the minds of NEAD-chain participants. This might happen either through the further elaboration of gift-like language and practices, or through a creative use of the cultural form and motivational vocabulary, but not necessarily the legal and institutional machinery, of contract.

Removal of bacteria from boar ejaculates by Single Layer Centrifugation can reduce the use of antibiotics in semen extenders.

PubMed

Morrell, J M; Wallgren, M

2011-01-01

There is considerable interest world-wide in reducing the use of antibiotics to stem the development of antibiotic-resistant strains of bacteria. An alternative to the routine addition of antibiotics to semen extenders in livestock breeding would be to separate the spermatozoa from bacterial contaminants in the semen immediately after collection. The present study was designed to determine whether such separation was possible by Single Layer Centrifugation (SLC) using the colloid Androcoll™-P. The results showed that complete removal (6 out of 10 samples), or considerable reduction of bacterial contaminants (4 out of 10 samples) was possible with this method. The type of bacteria and/or the length of time between collection and SLC-processing affected the removal of bacteria, with motile flagellated bacteria being more likely to be present after SLC than non-flagellated bacteria. Although further studies are necessary, these preliminary results suggest that the use of SLC when processing boar semen for AI doses might enable antibiotic usage in semen extenders to be reduced.

[Sustainable Implementation of Evidence-Based Programmes in Health Promotion: A Theoretical Framework and Concept of Interactive Knowledge to Action].

PubMed

Rütten, A; Wolff, A; Streber, A

2016-03-01

This article discusses 2 current issues in the field of public health research: (i) transfer of scientific knowledge into practice and (ii) sustainable implementation of good practice projects. It also supports integration of scientific and practice-based evidence production. Furthermore, it supports utilisation of interactive models that transcend deductive approaches to the process of knowledge transfer. Existing theoretical approaches, pilot studies and thoughtful conceptual considerations are incorporated into a framework showing the interplay of science, politics and prevention practice, which fosters a more sustainable implementation of health promotion programmes. The framework depicts 4 key processes of interaction between science and prevention practice: interactive knowledge to action, capacity building, programme adaptation and adaptation of the implementation context. Ensuring sustainability of health promotion programmes requires a concentrated process of integrating scientific and practice-based evidence production in the context of implementation. Central to the integration process is the approach of interactive knowledge to action, which especially benefits from capacity building processes that facilitate participation and systematic interaction between relevant stakeholders. Intense cooperation also induces a dynamic interaction between multiple actors and components such as health promotion programmes, target groups, relevant organisations and social, cultural and political contexts. The reciprocal adaptation of programmes and key components of the implementation context can foster effectiveness and sustainability of programmes. Sustainable implementation of evidence-based health promotion programmes requires alternatives to recent deductive models of knowledge transfer. Interactive approaches prove to be promising alternatives. Simultaneously, they change the responsibilities of science, policy and public health practice. Existing boundaries within disciplines and sectors are overcome by arranging transdisciplinary teams as well as by developing common agendas and procedures. Such approaches also require adaptations of the structure of research projects such as extending the length of funding. © Georg Thieme Verlag KG Stuttgart · New York.

Eleven essential steps to purchasing or selling a medical practice.

PubMed

Barrett, William

2014-01-01

Based on our experience in representing more than 100 doctors and medical specialists in practice sales and acquisitions, we have identified 11 key considerations important to a deal. There are several issues to consider while going through the process of buying or selling a practice including the implementation of a "letter of intent" as a first step rather than drafting a contract, securing a lease, and verifying the property is not in violation of the local zoning requirements. There are also considerations with regard to the patients, which range from how will the accounts receivable at the time of the closing be handled to who is responsible for the handling of continued treatment in an ongoing case after a deal is finalized. This article details these considerations and more.

In addition, basic recommendations for the assessment of DMLs are made, including increased availability of assessments in various languages, use of multiple sources of individual and family data, assessment of all languages, and incorporation of a strong assessment component (that includes nondiscrimination practices) into teacher preparation programs.

Accuracy & Computational Considerations for Wide--Angle One--way Seismic Propagators and Multiple Scattering by Invariant Embedding

NASA Astrophysics Data System (ADS)

Thomson, C. J.

2004-12-01

Pseudodifferential operators (PSDOs) yield in principle exact one--way seismic wave equations, which are attractive both conceptually and for their promise of computational efficiency. The one--way operators can be extended to include multiple--scattering effects, again in principle exactly. In practice approximations must be made and, as an example, the variable--wavespeed Helmholtz equation for scalar waves in two space dimensions is here factorized to give the one--way wave equation. This simple case permits clear identification of a sequence of physically reasonable approximations to be used when the mathematically exact PSDO one--way equation is implemented on a computer. As intuition suggests, these approximations hinge on the medium gradients in the direction transverse to the main propagation direction. A key point is that narrow--angle approximations are to be avoided in the interests of accuracy. Another key consideration stems from the fact that the so--called ``standard--ordering'' PSDO indicates how lateral interpolation of the velocity structure can significantly reduce computational costs associated with the Fourier or plane--wave synthesis lying at the heart of the calculations. The decision on whether a slow or a fast Fourier transform code should be used rests upon how many lateral model parameters are truly distinct. A third important point is that the PSDO theory shows what approximations are necessary in order to generate an exponential one--way propagator for the laterally varying case, representing the intuitive extension of classical integral--transform solutions for a laterally homogeneous medium. This exponential propagator suggests the use of larger discrete step sizes, and it can also be used to approach phase--screen like approximations (though the latter are not the main interest here). Numerical comparisons with finite--difference solutions will be presented in order to assess the approximations being made and to gain an understanding of computation time differences. The ideas described extend to the three--dimensional, generally anisotropic case and to multiple scattering by invariant embedding.

Extended-Range High-Resolution Dynamical Downscaling over a Continental-Scale Domain

NASA Astrophysics Data System (ADS)

Husain, S. Z.; Separovic, L.; Yu, W.; Fernig, D.

2014-12-01

High-resolution mesoscale simulations, when applied for downscaling meteorological fields over large spatial domains and for extended time periods, can provide valuable information for many practical application scenarios including the weather-dependent renewable energy industry. In the present study, a strategy has been proposed to dynamically downscale coarse-resolution meteorological fields from Environment Canada's regional analyses for a period of multiple years over the entire Canadian territory. The study demonstrates that a continuous mesoscale simulation over the entire domain is the most suitable approach in this regard. Large-scale deviations in the different meteorological fields pose the biggest challenge for extended-range simulations over continental scale domains, and the enforcement of the lateral boundary conditions is not sufficient to restrict such deviations. A scheme has therefore been developed to spectrally nudge the simulated high-resolution meteorological fields at the different model vertical levels towards those embedded in the coarse-resolution driving fields derived from the regional analyses. A series of experiments were carried out to determine the optimal nudging strategy including the appropriate nudging length scales, nudging vertical profile and temporal relaxation. A forcing strategy based on grid nudging of the different surface fields, including surface temperature, soil-moisture, and snow conditions, towards their expected values obtained from a high-resolution offline surface scheme was also devised to limit any considerable deviation in the evolving surface fields due to extended-range temporal integrations. The study shows that ensuring large-scale atmospheric similarities helps to deliver near-surface statistical scores for temperature, dew point temperature and horizontal wind speed that are better or comparable to the operational regional forecasts issued by Environment Canada. Furthermore, the meteorological fields resulting from the proposed downscaling strategy have significantly improved spatiotemporal variance compared to those from the operational forecasts, and any time series generated from the downscaled fields do not suffer from discontinuities due to switching between the consecutive forecasts.

This study compares the scope of practice of Dutch dental hygienists (DHs) educated through a 2- or 3-year curriculum ('old-style DHs') with that of hygienists educated through a new extended 4-year curriculum leading to a bachelor's degree ('new-style DHs'), with the aim to investigate whether an extended scope of practice positively affects perceived skill variety, autonomy and job satisfaction. The questionnaires were obtained from old- and new-style DHs (n = 413, response 38%; n = 219, response 59%, respectively), in which respondents had recorded their dental tasks, perceived skill variety, autonomy and job satisfaction. T -tests were used to analyse differences between old- and new-style DHs, and regression analyses were performed to assess the relation between scope of practice and skill variety, autonomy and job satisfaction. New-style DHs have a more extended scope of practice compared with old-style DHs. Despite their more complex jobs, which are theoretically related to higher job satisfaction, new-style DHs perceive lower autonomy and job satisfaction (P < 0.05). Skill variety is the strongest predictor for DHs' job satisfaction (β = 0.462), followed by autonomy (β = 0.202) and caries decisive tasks, the last affecting job satisfaction negatively (β = -0.149). Self-employment is the strongest significant predictor for autonomy (β = 0.272). The core business of DHs remains the prevention and periodontology services. New-style DHs combine these tasks with extended tasks in the caries field, which can lead to comparatively less job satisfaction, because of a lower experienced autonomy in performing these extended tasks. © 2012 John Wiley & Sons A/S.

The study aimed to explore the views of general practitioners (GPs), nurses and physiotherapists towards extending the role of sickness certification beyond the medical profession in primary care. Fifteen GPs, seven nurses and six physiotherapists were selected to achieve varied respondent characteristics including sex, geographical location, service duration and post-graduate specialist training. Constant-comparative qualitative analysis of data from 28 semi-structured telephone interviews was undertaken. The majority of respondents supported the extended role concept; however members of each professional group also rejected the notion. Respondents employed four different legitimacy claims to justify their views and define their occupational boundaries in relation to sickness certification practice. Condition-specific legitimacy, the ability to adopt a holistic approach to sickness certification, system efficiency and control-related arguments were used to different degrees by each occupation. Practical suggestions for the extension of the sickness certification role beyond the medical profession are underpinned by the sociological theory of professional identity. Extending the authority to certify sickness absence beyond the medical profession is not simply a matter of addressing practical and organisational obstacles. There is also a need to consider the impact on, and preferences of, the specific occupations and their respective boundary claims. This paper explores the implications of extending the sick certification role beyond general practice. We conclude that the main policy challenge of such a move is to a) persuade GPs to relinquish this role (or to share it with other professions), and b) to understand the 'boundary work' involved.

Physician to investigator: clinical practice to clinical research--ethical, operational, and financial considerations.

PubMed

Pierre, Christine

2008-01-01

Physicians who participate in clinical research studies gain benefits for themselves, their practice, and their patients. Historically, private practice physicians have chosen to defer to their counterparts in academic medicine when it comes to contributing to scientific advancement through clinical studies. A growing number of private practice physicians are now taking a serious second look and deciding that there are unique benefits for both the practice and the patient. Physicians who decide to participate in clinical research should give serious consideration to the time and resources that are required to meet both federal regulations and industry standards. In addition, ethical and scientific principles for assuring the protection of human research subjects must be a paramount commitment.

Medicaid Consent to Sterilization forms: historical, practical, ethical, and advocacy considerations.

Block-Abraham, Dana; Arora, Kavita S; Tate, Danielle; Gee, Rebekah E

2015-06-01

The US government developed a Medicaid Consent to Sterilization form in the mid-1970s to protect vulnerable populations from coerced sterilization. US health care practices have evolved significantly since that time. The form, however, has not changed, and may be preventing access to desired services for the same vulnerable populations it was originally created to protect. This paper discusses the relevant historical, practical use, ethical, and advocacy considerations of the Medicaid sterilization consent form and proposes changes to make the form more pertinent to today's medical environment.

An overview of Medicare reimbursement regulations for advanced practice nurses.

PubMed

Frakes, Michael A; Evans, Tracylain

2006-01-01

The federal government spends nearly 15% of the budget on Medicare services annually, and advanced practice nurses are eligible for reimbursement from that pool. The regulations governing reimbursement are complex because of the social, political, and financial pressures involved in their development. Although economic viability and due diligence considerations make it incumbent on advanced practice nurses to understand the rules, the profession, as a whole, has knowledge deficits in this area. The essentials of regulatory development and structure are reviewed and considerations for optimizing reimbursement are described.

Induction of labor in resource-limited settings has the potential to significantly improve health outcomes for both mothers and infants. However, there are relatively little context-specific data to guide practice, and few specific guidelines. Also, there may be considerable issues regarding the facilities and organizational capacities necessary to support safe practices in many aspects of obstetrical practice, and for induction of labor in particular. Herein we describe the various opportunities as well as challenges presented by induction of labor in these settings. Copyright © 2015 Elsevier Inc. All rights reserved.

In recent decades, community pharmacies reported a change of business model, whereby a shift from traditional services to the provision of extended roles was observed. However, such delivery of extended pharmacy services (EPS) is reported from the developed world, and there is scarcity of information from the developing nations. Within this context, the present study was aimed to explore knowledge, perception and attitude of community pharmacists (CPs) about EPS and their readiness and acceptance for practice change in the city of Lahore, Pakistan. A qualitative approach was used to gain an in-depth knowledge of the issues. By using a semi-structured interview guide, 12 CPs practicing in the city of Lahore, Pakistan were conveniently selected. All interviews were audio-taped, transcribed verbatim, and were then analyzed for thematic contents by the standard content analysis framework. Thematic content analysis yielded five major themes. (1) Familiarity with EPS, (2) current practice of EPS, (3) training needed to provide EPS, (4) acceptance of EPS and (5) barriers toward EPS. Majority of the CPs were unaware of EPS and only a handful had the concept of extended services. Although majority of our study respondents were unaware of pharmaceutical care, they were ready to accept practice change if provided with the required skills and training. Lack of personal knowledge, poor public awareness, inadequate physician-pharmacist collaboration and deprived salary structures were reported as barriers towards the provision of EPS at the practice settings. Although the study reported poor awareness towards EPS, the findings indicated a number of key themes that can be used in establishing the concept of EPS in Pakistan. Over all, CPs reported a positive attitude toward practice change provided to the support and facilitation of health and community based agencies in Pakistan.

It is shown that the consideration of the density of states variation in nanoscale electrochemical systems yields modulations in the rate constant and concomitant electrical currents. The proposed models extend the utility of Marcus-Hush-Chidsey (MHC) kinetics to a larger class of materials and could be used as a test of dimensional character. The implications of the study are of much significance to an understanding and modulation of charge transfer nanostructured electrodes.

The Science and Prospects of Astrophysical Observations with New Horizons

NASA Astrophysics Data System (ADS)

Nguyen, Chi; Zemcov, Michael; Cooray, Asantha; Lisse, Carey; Poppe, Andrew

2018-01-01

Astrophysical observation from the outer solar system provides a unique and quiet vantage point from which to understand our cosmos. If properly designed, such observations enable several niche science cases that are difficult or impossible to perform near Earth. NASA's New Horizons mission includes several instruments with ~10cm telescopes that provide imaging capability from UV to near-IR wavelengths with moderate spectral resolution. A carefully designed survey can optimize the expendable propellant and limited data telemetry bandwidth to allow several unique measurements, including a detailed understanding of the cosmic extragalactic background light in the optical and near-IR, studies of the local and extragalactic UV background, measurements of the properties of dust and ice in the outer solar system, searches for moons and other faint structures around exoplanets, and determinations of the mass of planets far from their parent stars using gravitational microlensing. New Horizons is currently in an extended mission, that will conclude in 2021, designed to survey distant objects in the Kuiper Belt at high phase angles and perform a close flyby of KBO 2014 MU69. Afterwards, the astrophysics community will have a unique, generational opportunity to use this mission for astronomical observations at heliocentric distances beyond 50 AU. In this poster, we present the science case for an extended 2021 - 2026 astrophysics mission, and discuss some of the practical considerations that must be addressed to maximize the potential science return.

Cancer Risk Assessment for Space Radiation

NASA Technical Reports Server (NTRS)

Richmond, Robert C.; Cruz, Angela; Bors, Karen; Curreri, Peter A. (Technical Monitor)

2001-01-01

Predicting the occurrence of human cancer following exposure to any agent causing genetic damage is a difficult task. This is because the uncertainty of uniform exposure to the damaging agent, and the uncertainty of uniform processing of that damage within a complex set of biological variables, degrade the confidence of predicting the delayed expression of cancer as a relatively rare event within any given clinically normal individual. The radiation health research priorities for enabling long-duration human exploration of space were established in the 1996 NRC Report entitled 'Radiation Hazards to Crews of Interplanetary Missions: Biological Issues and Research Strategies'. This report emphasized that a 15-fold uncertainty in predicting radiation-induced cancer incidence must be reduced before NASA can commit humans to extended interplanetary missions. That report concluded that the great majority of this uncertainty is biologically based, while a minority is physically based due to uncertainties in radiation dosimetry and radiation transport codes. Since that report, the biologically based uncertainty has remained large, and the relatively small uncertainty associated with radiation dosimetry has increased due to the considerations raised by concepts of microdosimetry. In a practical sense, however, the additional uncertainties introduced by microdosimetry are encouraging since they are in a direction of lowered effective dose absorbed through infrequent interactions of any given cell with the high energy particle component of space radiation. Additional information is contained in the original extended abstract.

Feasibility study: refinement of the TTC concept by additional rules based on in silico and experimental data.

PubMed

Hauge-Nilsen, Kristin; Keller, Detlef

2015-01-01

Starting from a single generic limit value, the threshold of toxicological concern (TTC) concept has been further developed over the years, e.g., by including differentiated structural classes according to the rules of Cramer et al. (Food Chem Toxicol 16: 255-276, 1978). In practice, the refined TTC concept of Munro et al. (Food Chem Toxicol 34: 829-867, 1996) is often applied. The purpose of this work was to explore the possibility of refining the concept by introducing additional structure-activity relationships and available toxicity data. Computer modeling was performed using the OECD Toolbox. No observed (adverse) effect level (NO(A)EL) data of 176 substances were collected in a basic data set. New subgroups were created applying the following criteria: extended Cramer rules, low bioavailability, low acute toxicity, no protein binding affinity, and consideration of predicted liver metabolism. The highest TTC limit value of 236 µg/kg/day was determined for a subgroup that combined the criteria "no protein binding affinity" and "predicted liver metabolism." This value was approximately eight times higher than the original Cramer class 1 limit value of 30 µg/kg/day. The results of this feasibility study indicate that inclusion of the proposed criteria may lead to improved TTC values. Thereby, the applicability of the TTC concept in risk assessment could be extended which could reduce the need to perform animal tests.

Four years of training in family medicine: implications for residency redesign.

PubMed

Sigmon, J Lewis; McPherson, Vanessa; Little, John M

2012-09-01

In light of the ongoing consideration for extending the length of residency education in family medicine in the United States, this paper reports the findings from a retrospective, qualitative study of six family physicians that elected to extend their residency training from 3 to 4 years. Each participant completed a written questionnaire and a structured personal interview focusing on various aspects of career development resulting from the additional year of training. The authors independently evaluated these interviews to identify major themes. All the participants were found to have been involved in teaching medicine, valued a more flexible and expanded curriculum, and appreciated their individualized curricula-based on their respective career interests. Given the opportunity, each would opt again for a fourth year of training. There were mixed opinions as to whether the fourth year should be required of all family medicine residents. Other perceived benefits reported were: a better opportunity to find a personally satisfactory practice, additional time for gaining clarity about career plans, and a higher beginning salary as a result of the additional skills and experiences gained. This study of mid-career physicians supports that a fourth-year (PGY4) curriculum in family medicine may enhance subsequent career satisfaction. Further studies of residents in other PGY4 training programs are necessary to assess outcomes comparing our findings as well as guide the discipline's leaders in residency redesign.

Surface phenomena related to mirror degradation in extreme ultraviolet (EUV) lithography

NASA Astrophysics Data System (ADS)

Madey, Theodore E.; Faradzhev, Nadir S.; Yakshinskiy, Boris V.; Edwards, N. V.

2006-12-01

One of the most promising methods for next generation device manufacturing is extreme ultraviolet (EUV) lithography, which uses 13.5 nm wavelength radiation generated from freestanding plasma-based sources. The short wavelength of the incident illumination allows for a considerable decrease in printed feature size, but also creates a range of technological challenges not present for traditional optical lithography. Contamination and oxidation form on multilayer reflecting optics surfaces that not only reduce system throughput because of the associated reduction in EUV reflectivity, but also introduce wavefront aberrations that compromise the ability to print uniform features. Capping layers of ruthenium, films ∼2 nm thick, are found to extend the lifetime of Mo/Si multilayer mirrors used in EUV lithography applications. However, reflectivities of even the Ru-coated mirrors degrade in time during exposure to EUV radiation. Ruthenium surfaces are chemically reactive and are very effective as heterogeneous catalysts. In the present paper we summarize the thermal and radiation-induced surface chemistry of bare Ru exposed to gases; the emphasis is on H2O vapor, a dominant background gas in vacuum processing chambers. Our goal is to provide insights into the fundamental physical processes that affect the reflectivity of Ru-coated Mo/Si multilayer mirrors exposed to EUV radiation. Our ultimate goal is to identify and recommend practices or antidotes that may extend mirror lifetimes.

Eight overarching thematic recommendations, with proposed corresponding actions for consideration by funding agencies, professional societies, and the research community emerged from the collective intellectual discourse. The themes are (i) extending the reach of epidemiology beyond discovery and etiologic research to include multilevel analysis, intervention evaluation, implementation, and outcomes research; (ii) transforming the practice of epidemiology by moving toward more access and sharing of protocols, data, metadata, and specimens to foster collaboration, to ensure reproducibility and replication, and acceleratemore » translation; (iii) expanding cohort studies to collect exposure, clinical, and other information across the life course and examining multiple health-related endpoints; (iv) developing and validating reliable methods and technologies to quantify exposures and outcomes on a massive scale, and to assess concomitantly the role of multiple factors in complex diseases; (v) integrating big data science into the practice of epidemiology; (vi) expanding knowledge integration to drive research, policy, and practice; (vii) transforming training of 21st century epidemiologists to address interdisciplinary and translational research; and (viii) optimizing the use of resources and infrastructure for epidemiologic studies. These recommendations can transform cancer epidemiology and the field of epidemiology, in general, by enhancing transparency, interdisciplinary collaboration, and strategic applications of new technologies. They should lay a strong scientific foundation for accelerated translation of scientific discoveries into individual and population health benefits.« less

What factors influence physiotherapy service provision in rural communities? A pilot study.

2014-06-01

To obtain stakeholder perspectives on factors influencing rural physiotherapy service provision and insights into decision making about service provision. Purposive sampling, open-ended survey questions and semi-structured interviews were used in this exploratory, qualitative study. A rural centre and its regional referral centre formed the pilot sites. Nine participant perspectives were obtained on rural physiotherapy services. Stakeholder perspectives on factors influencing rural physiotherapy service provision and service level decision making. Workforce capacity and capability, decision maker's knowledge of the role and scope of physiotherapy, consideration of physiotherapy within resource allocation decisions and proof of practice emerged as key issues. The latter three were particularly reflected in public sector participant comments. Business models and market size were identified factors in influencing private practice. Influencing factors described by participants both align and extend our understanding of issues described in the rural physiotherapy literature. Participant insights add depth and meaning to quantitative data by revealing impacts on local service provision. Available funding and facility priorities were key determinants of public sector physiotherapy service provision, with market size and business model appearing more influential in private practice. The level of self direction or choice about which services to provide, emerged as a point of difference between public and private providers. Decisions by public sector physiotherapists about service provision appear constrained by existing capacity and workload. Further research into service level decision making might provide valuable insights into rural health service delivery. © 2014 National Rural Health Alliance Inc.

A sup-score test for the cure fraction in mixture models for long-term survivors.

PubMed

Hsu, Wei-Wen; Todem, David; Kim, KyungMann

2016-12-01

The evaluation of cure fractions in oncology research under the well known cure rate model has attracted considerable attention in the literature, but most of the existing testing procedures have relied on restrictive assumptions. A common assumption has been to restrict the cure fraction to a constant under alternatives to homogeneity, thereby neglecting any information from covariates. This article extends the literature by developing a score-based statistic that incorporates covariate information to detect cure fractions, with the existing testing procedure serving as a special case. A complication of this extension, however, is that the implied hypotheses are not typical and standard regularity conditions to conduct the test may not even hold. Using empirical processes arguments, we construct a sup-score test statistic for cure fractions and establish its limiting null distribution as a functional of mixtures of chi-square processes. In practice, we suggest a simple resampling procedure to approximate this limiting distribution. Our simulation results show that the proposed test can greatly improve efficiency over tests that neglect the heterogeneity of the cure fraction under the alternative. The practical utility of the methodology is illustrated using ovarian cancer survival data with long-term follow-up from the surveillance, epidemiology, and end results registry. © 2016, The International Biometric Society.

Managing seafood processing wastewater on the Oregon coast: A time of transition

Anderson, M.D.; Miner, J.R.

1997-12-01

Seafood processors along the Oregon coast practice a wastewater management plan that is unique within the state. Most of these operations discharge wastewater under a General Permit issued by the Oregon Department of Environmental Quality (DEQ) that requires only that they screen the wastewater to remove particles that will not pass through a 40 mesh screen. The General Permit was issued in February of 1992 and was scheduled to expire at the end of December, 1996. It has been extended until a replacement is adopted. Alternatives are currently under consideration by the DEQ. A second issue is the increasing competitionmore » for water within the coastal communities that are experiencing a growing tourist industry and a static water supply. Tourism and seafood processing both have their peak water demands during the summer months when fresh water supplies are most limited. Disposal of solid wastes has been simplified for many of the processors along the Lower Columbia River by a Fisheries Enhancement Program which allows processors to grind the solid waste then to discharge it into the stream under appropriate tidal conditions. There is no data which indicates water quality damage from this practice nor is there clear evidence of enhanced fishery productivity.« less

Extending the Measurement Range of AN Optical Surface Profiler.

NASA Astrophysics Data System (ADS)

Cochran, Eugene Rowland, III

This dissertation investigates a method for extending the measurement range of an optical surface profiling instrument. The instrument examined in these experiments is a computer -controlled phase-modulated interference microscope. Because of its ability to measure surfaces with a high degree of vertical resolution as well as excellent lateral resolution, this instrument is one of the most favorable candidates for determining the microtopography of optical surfaces. However, the data acquired by the instrument are restricted to a finite lateral and vertical range. To overcome this restriction, the feasibility of a new testing technique is explored. By overlapping a series of collinear profiles the limited field of view of this instrument can be increased and profiles that contain longer surface wavelengths can be examined. This dissertation also presents a method to augment both the vertical and horizontal dynamic range of the surface profiler by combining multiple subapertures and two-wavelength techniques. The theory, algorithms, error sources, and limitations encountered when concatenating a number of profiles are presented. In particular, the effects of accumulated piston and tilt errors on a measurement are explored. Some practical considerations for implementation and integration into an existing system are presented. Experimental findings and results of Monte Carlo simulations are also studied to explain the effects of random noise, lateral position errors, and defocus across the CCD array on measurement results. These results indicate the extent to which the field of view of the profiler may be augmented. A review of current methods of measuring surface topography is included, to provide for a more coherent text, along with a summary of pertinent measurement parameters for surface characterization. This work concludes with recommendations for future work that would make subaperture -testing techniques more reliable for measuring the microsurface structure of a material over an extended region.

The Psychological Benefits from Reconceptualizing Music-Making as Mindfulness Practice.

Steinfeld, Matthew; Brewer, Judson

2015-06-01

While the music psychology and education literatures have devoted considerable attention to how musical instrumentalists practice their instruments, less formal scholarly attention has been given in consideration of what it means to maintain a musical "practice" over time and across context. In this paper, the practice of mindfulness meditation is used as heuristic, arguing for a view of mindfulness meditation as a formalized de-specialization of the infinite number of other activities with which people can achieve mindfulness. Sitting meditation, requiring of one to observe the contents of their mind unmediated, can serve as a useful model for the musician in understanding the phenomenology of the music-making process and the "flow" states that can result from an embodied musical practice. Finally, reconceptualizing music-making as a mindfulness practice is considered with psychological and pedagogical implications relevant for developing musicians.

The elliptical polarization dependence of the two-photon absorption coefficient β in InP has been measured by the extended Z-scan technique for thick materials in the wavelength range from 1640 to 1800 nm. The analytical formula of the Z-scan technique has been extended with consideration of multiple reflections. The Z-scan results have been fitted very well by the formula and β has been evaluated accurately. The three independent elements of the third-order nonlinear susceptibility tensor in InP have also been determined accurately from the elliptical polarization dependence of β.

Practical considerations in Bayesian fusion of point sensors

NASA Astrophysics Data System (ADS)

Johnson, Kevin; Minor, Christian

2012-06-01

Sensor data fusion is and has been a topic of considerable research, but rigorous and quantitative understanding of the benefits of fusing specific types of sensor data remains elusive. Often, sensor fusion is performed on an ad hoc basis with the assumption that overall detection capabilities will improve, only to discover later, after expensive and time consuming laboratory and/or field testing that little advantage was gained. The work presented here will discuss these issues with theoretical and practical considerations in the context of fusing chemical sensors with binary outputs. Results are given for the potential performance gains one could expect with such systems, as well as the practical difficulties involved in implementing an optimal Bayesian fusion strategy with realistic scenarios. Finally, a discussion of the biases that inaccurate statistical estimates introduce into the results and their consequences is presented.

Conscientious refusal and health professionals: does religion make a difference?

PubMed

Weinstock, Daniel

2014-01-01

Freedom of Conscience and Freedom of Religion should be taken to protect two distinct sets of moral considerations. The former protects the ability of the agent to reflect critically upon the moral and political issues that arise in her society generally, and in her professional life more specifically. The latter protects the individual's ability to achieve secure membership in a set of practices and rituals that have as a moral function to inscribe her life in a temporally extended narrative. Once these grounds are distinguished, it becomes more difficult to grant healthcare professionals' claims to religious exemptions on the basis of the latter than it is on the basis of the former. While both sets of considerations generate 'internal reasons' for rights to accommodation, the relevant 'external' reasons present in the case of claims of moral conscience do not possess analogues in the case of claims of religious conscience. However, the argument applies only to 'irreducibly religious' claims, that is to claims that cannot be translated into moral vocabulary. What's more, there may be reasons to grant the claims of religious persons to exemptions that have to do not with the nature of the claims, but with the beneficial effects that the presence of religious persons may have in the context of the healthcare institutions of multi-faith societies. © 2013 John Wiley & Sons Ltd.

Kinetic Monte Carlo Simulations of Diffusion in Environmental Barrier Coating Materials

NASA Technical Reports Server (NTRS)

Good, Brian

2017-01-01

Ceramic Matrix Components (CMC) components for use in turbine engines offer a number of advantages compared with current practice. However, such components are subject to degradation through a variety of mechanisms. In particular, in the hot environment inside a turbine in operation a considerable amount of water vapor is present, and this can lead to corrosion and recession. Environmental Barrier Coating (EBC) systems that limit the amount of oxygen and water reaching the component are required to reduce this degradation and extend component life. A number of silicate-based materials are under consideration for use in such coating systems, including Yttterbium and Yttrium di- and monosilicates. In this work, we present results of kinetic Monte Carlo computer simulations of oxygen diffusion in Yttrium disilicate, and compare with previous work on Yttterbium disilicate. Coatings may also exhibit cracking, and the cracks can provide a direct path for oxygen to reach the component. There is typically a bond coat between the coating and component surface, but the bond coat material is generally chosen for properties other than low oxygen diffusivity. Nevertheless, the degree to which the bond coat can inhibit oxygen diffusion is of interest, as it may form the final defense against oxygen impingement on the component. We have therefore performed similar simulations of oxygen diffusion through HfSiO4, a proposed bond coat material.

Emergent Theorisations in Modelling the Teaching of Two Science Teachers

NASA Astrophysics Data System (ADS)

Monteiro, Rute; Carrillo, José; Aguaded, Santiago

2008-05-01

The main goal of this study is to understand the teacher’s thoughts and action when he/she is immersed in the activity of teaching. To do so, it describes the procedures used to model two teachers’ practice with respect to the topic of Plant Diversity. Starting from a consideration of the theoretical constructs of script, routine and improvisation, this modelling basically corresponds to a microanalysis of the teacher’s beliefs, goals and knowledge, as highlighted in the classroom activity. From the process of modelling certain theorisations emerge, corresponding to abstractions gained from concrete cases. They allow us to foreground strong relationships between the beliefs and actions, and the knowledge and objectives of the teacher in action. Envisaged as conjectures rather than generalisations, these abstractions could possibly be extended to other cases, and tested out with new case studies, questioning their formulation or perhaps demonstrating that the limits of their applicability do not go beyond the original cases.

Faulty judgment, expert opinion, and decision-making capacity.

PubMed

Silberfeld, M; Checkland, D

1999-08-01

An assessment of decision-making capacity is the accepted procedure for determining when a person is not competent. An inferential gap exists between the criteria for capacity specific abilities and the legal requirements to understand relevant information and appreciate the consequences of a decision. This gap extends to causal influences on a person's capacity to decide. Using a published case of depression, we illustrate that assessors' uses of diagnostic information is frequently not up to the task of bridging this inferential gap in a justifiable way. We then describe cases of faulty judgement which challenge the understanding of diagnostic causal influences. These cases help to clarify the nature of the expertise required for capacity assessments. In practice, the requirements of decision-making capacity are often abandoned to other considerations due to a lack of requisite expertise. The legal policy supporting decision-making capacity as a means to protective intervention is justified only if the requisite expertise is developed. We propose the requisite expertise to be developed in the long term as a distinct multidisciplinary endeavour.

Asynchronous adaptive time step in quantitative cellular automata modeling

PubMed Central

Zhu, Hao; Pang, Peter YH; Sun, Yan; Dhar, Pawan

2004-01-01

Background The behaviors of cells in metazoans are context dependent, thus large-scale multi-cellular modeling is often necessary, for which cellular automata are natural candidates. Two related issues are involved in cellular automata based multi-cellular modeling: how to introduce differential equation based quantitative computing to precisely describe cellular activity, and upon it, how to solve the heavy time consumption issue in simulation. Results Based on a modified, language based cellular automata system we extended that allows ordinary differential equations in models, we introduce a method implementing asynchronous adaptive time step in simulation that can considerably improve efficiency yet without a significant sacrifice of accuracy. An average speedup rate of 4–5 is achieved in the given example. Conclusions Strategies for reducing time consumption in simulation are indispensable for large-scale, quantitative multi-cellular models, because even a small 100 × 100 × 100 tissue slab contains one million cells. Distributed and adaptive time step is a practical solution in cellular automata environment. PMID:15222901

Discontinuous Galerkin Methods for NonLinear Differential Systems

Barth, Timothy; Mansour, Nagi (Technical Monitor)

2001-01-01

This talk considers simplified finite element discretization techniques for first-order systems of conservation laws equipped with a convex (entropy) extension. Using newly developed techniques in entropy symmetrization theory, simplified forms of the discontinuous Galerkin (DG) finite element method have been developed and analyzed. The use of symmetrization variables yields numerical schemes which inherit global entropy stability properties of the PDE (partial differential equation) system. Central to the development of the simplified DG methods is the Eigenvalue Scaling Theorem which characterizes right symmetrizers of an arbitrary first-order hyperbolic system in terms of scaled eigenvectors of the corresponding flux Jacobian matrices. A constructive proof is provided for the Eigenvalue Scaling Theorem with detailed consideration given to the Euler equations of gas dynamics and extended conservation law systems derivable as moments of the Boltzmann equation. Using results from kinetic Boltzmann moment closure theory, we then derive and prove energy stability for several approximate DG fluxes which have practical and theoretical merit.

Regeneration of injured skeletal muscle after the injury

2013-01-01

Summary Muscle injuries are one of the most common traumas occurring in sports. Despite their clinical importance, few clinical studies exist on the treatment of these traumas. Thus, the current treatment recommendations for muscle injuries have either been derived from experimental studies or been tested only empirically. Although non operative treatment should almost always be the 1st choice as it results in good functional outcomes in the majority of athletes with muscle injuries, the consequences of failed treatment can be very dramatic, possibly postponing an athlete’s return to sports for weeks or even months. Moreover, the recognition of some basic principles of skeletal muscle regeneration and healing processes can considerably help in both avoiding the imminent dangers and accelerating the return to competition. Accordingly, in this review, the authors have summarized the prevailing understanding on the biology of muscle regeneration in hopes of extending these findings to clinical practice in an attempt to propose an evidence-based approach for the diagnosis and optimal treatment of skeletal muscle injuries.

Rational Chebyshev spectral transform for the dynamics of broad-area laser diodes

DOE Office of Scientific and Technical Information (OSTI.GOV)

Javaloyes, J., E-mail: julien.javaloyes@uib.es; Balle, S.

2015-10-01

This manuscript details the use of the rational Chebyshev transform for describing the transverse dynamics of broad-area laser diodes and amplifiers. This spectral method can be used in combination with the delay algebraic equations approach developed in [1], which substantially reduces the computation time. The theory is presented in such a way that it encompasses the case of the Fourier spectral transform presented in [2] as a particular case. It is also extended to the consideration of index guiding with an arbitrary transverse profile. Because their domain of definition is infinite, the convergence properties of the Chebyshev rational functions allowmore » handling the boundary conditions with higher accuracy than with the previously studied Fourier transform method. As practical examples, we solve the beam propagation problem with and without index guiding: we obtain excellent results and an improvement of the integration time between one and two orders of magnitude as compared with a fully distributed two dimensional model.« less

Examining the design features of a communication-rich, problem-centred mathematics professional development

NASA Astrophysics Data System (ADS)

de Araujo, Zandra; Orrill, Chandra Hawley; Jacobson, Erik

2018-04-01

While there is considerable scholarship describing principles for effective professional development, there have been few attempts to examine these principles in practice. In this paper, we identify and examine the particular design features of a mathematics professional development experience provided for middle grades teachers over 14 weeks. The professional development was grounded in a set of mathematical tasks that each had one right answer, but multiple solution paths. The facilitator engaged participants in problem solving and encouraged participants to work collaboratively to explore different solution paths. Through analysis of this collaborative learning environment, we identified five design features for supporting teacher learning of important mathematics and pedagogy in a problem-solving setting. We discuss these design features in depth and illustrate them by presenting an elaborated example from the professional development. This study extends the existing guidance for the design of professional development by examining and operationalizing the relationships among research-based features of effective professional development and the enacted features of a particular design.

Early lessons from schistosomiasis mass drug administration programs

PubMed Central

Secor, W. Evan

2015-01-01

Mass drug administration using praziquantel is the backbone of the current strategy for the control of schistosomiasis. As the theoretical plans have moved into practical application, certain challenges with this approach have surfaced, and it is likely that annual mass drug administration alone may not be sufficient to achieve program goals. However, mass drug administration is still the only available intervention that can be readily used in the wide variety of settings where schistosomiasis is endemic. The task then becomes how to improve this approach and identify what adjuncts to mass drug administration are effective, as programs move from morbidity control to elimination goals. Other aspects worthy of consideration include how best to employ new diagnostic tools to more easily identify where treatment is needed, and new formulations of praziquantel to extend the availability of treatment to all age groups. The aim of this review is to highlight both areas of challenge and of opportunity to improve the public health impact of schistosomiasis control programs. PMID:26937275

The feasibility of using optical communication systems for data telemetry from deep space vehicles to Earth based receivers is evaluated. Performance analysis shows that practical, photon counting optical systems can transmit data reliably at 30 to 40 dB high rates than existing RF systems, or can be used to extend the communication range by 15 to 20 dB. The advantages of pulse-position modulation (PPM) formats are discussed, and photon counting receiver structures designed for PPM decoding are described. The effects of background interference and weather on receiver performance are evaluated. Some consideration is given to tracking and beam pointing operations, since system performance ultimately depends on the accuracy to which these operations can be carried out. An example of a tracking and pointing system utilizing an optical uplink beacon is presented, and it is shown that microradian beam pointing is within the capabilities of state-of-the-art technology. Recommendations for future theoretical studies and component development programs are presented.

Real-Time Gait Cycle Parameter Recognition Using a Wearable Accelerometry System

Yang, Che-Chang; Hsu, Yeh-Liang; Shih, Kao-Shang; Lu, Jun-Ming

2011-01-01

This paper presents the development of a wearable accelerometry system for real-time gait cycle parameter recognition. Using a tri-axial accelerometer, the wearable motion detector is a single waist-mounted device to measure trunk accelerations during walking. Several gait cycle parameters, including cadence, step regularity, stride regularity and step symmetry can be estimated in real-time by using autocorrelation procedure. For validation purposes, five Parkinson’s disease (PD) patients and five young healthy adults were recruited in an experiment. The gait cycle parameters among the two subject groups of different mobility can be quantified and distinguished by the system. Practical considerations and limitations for implementing the autocorrelation procedure in such a real-time system are also discussed. This study can be extended to the future attempts in real-time detection of disabling gaits, such as festinating or freezing of gait in PD patients. Ambulatory rehabilitation, gait assessment and personal telecare for people with gait disorders are also possible applications. PMID:22164019

The perceived benefits of a two-year period of extended specialty training in general practice: the trainees' perspective.

PubMed

Agius, Steven; Lewis, Barry; Kirk, Bob; Hayden, Jacky

2014-01-01

Evidence suggests that, in the UK, the current three-year specialty training period in general practice is inadequate for equipping newly qualified GPs with mastery in all the necessary clinical and generic skills that would allow them to respond with optimum effect to the complexities and uncertainties of the generalist workplace. The North Western Deanery initiated an innovative pilot programme of extended (by 24 months) specialty training in general practice (GPST4-5). Nine ST3 trainees who had just 'graduated' from GPST, holding nMRCGP, were recruited, thereby formally deferring their application for a Certificate of Completion of Training (CCT). The programme was evaluated using established qualitative research techniques. Semi-structured interviews were conducted at fixed points and data were analysed for recurring discourses and themes using a framework thematic analysis. We obtained evidence of the benefits of extended specialty training in encouraging the development of clinical mastery alongside additional specialist skills, generalist and leadership competencies. We also identified the enabling factors for beneficial extended training, including workplace-based training under educational mentorship, combined with a blended learning programme and sustained expert- and peer-support.

Genetic methods for detection of antibiotic resistance: focus on extended-spectrum β-lactamases.

PubMed

Chroma, Magdalena; Kolar, Milan

2010-12-01

In 1928, the first antibiotic, penicillin, was discovered. That was the beginning of a great era in the development and prescription of antibiotics. However, the introduction of these antimicrobial agents into clinical practice was accompanied by the problem of antibiotic resistance. Currently, bacterial resistance to antibiotics poses a major problem in both hospital and community settings throughout the world. This review provides examples of modern genetic methods and their practical application in the field of extended-spectrum β-lactamase detection. Since extended-spectrum β-lactamases are the main mechanism of Gram-negative bacterial resistance to oxyimino-cephalosporins, rapid and accurate detection is requested in common clinical practice. Currently, the detection of extended-spectrum β-lactamases is primarily based on the determination of bacterial phenotypes rather than genotypes. This is because therapeutic decisions are based on assessing the susceptibility rather than presence of resistance genes. One of the main disadvantages of genetic methods is high costs, including those of laboratory equipment. On the other hand, if these modern methods are introduced into diagnostics, they often help in rapid and accurate detection of certain microorganisms or their resistance and pathogenic determinants.

Education, practical training and professional development for public health practitioners: a scoping review of the literature and insights for sustainable food system capacity-building.

PubMed

Wegener, Jessica; Fong, Debbie; Rocha, Cecilia

2018-06-01

Noting the upstream positioning of sustainable food systems (SFS) to multiple global crises, the present review described examples of emerging and promising practices to support SFS-oriented education, practical training (PT) and continuing professional development (CPD) among trainees and public health practitioners (PHP). A secondary objective was to compile the evidence into practical considerations for educators, supervising practitioners and professional associations. A scoping review of the literature published between 2007 and 2017 was conducted in May 2017 using four databases: CINAHL, MEDLINE, Scopus and HSSA, along with bibliography hand-searching and expert consultation. Articles were screened for relevance and specificity by independent raters. Nineteen articles were included for analysis. Two-thirds of the articles related to dietitians and public health nutritionists. Emerging practices included curriculum-based considerations, incorporation of 'sustainability' within professional competencies and self-reflection related to SFS. Descriptions of SFS-related education, PT and CPD practices appeared largely in the literature from developed countries. Articles converged on the need for ecosystems, food systems and sustainability considerations within and across practice to support current and future practitioners. There is growing interest in SFS but guidance to support educators and preceptors is lacking. Updates to dietary guidelines to reflect issues of sustainability are a timely prompt to examine the education, training and development needs of trainees and PHP. Practical examples of emerging practices can empower PHP to promote SFS in all areas of practice. More research is needed to address identified gaps in the literature and to improve SFS-specific education, PT and CPD.

Algorithm for Video Summarization of Bronchoscopy Procedures

PubMed Central

2011-01-01

Background The duration of bronchoscopy examinations varies considerably depending on the diagnostic and therapeutic procedures used. It can last more than 20 minutes if a complex diagnostic work-up is included. With wide access to videobronchoscopy, the whole procedure can be recorded as a video sequence. Common practice relies on an active attitude of the bronchoscopist who initiates the recording process and usually chooses to archive only selected views and sequences. However, it may be important to record the full bronchoscopy procedure as documentation when liability issues are at stake. Furthermore, an automatic recording of the whole procedure enables the bronchoscopist to focus solely on the performed procedures. Video recordings registered during bronchoscopies include a considerable number of frames of poor quality due to blurry or unfocused images. It seems that such frames are unavoidable due to the relatively tight endobronchial space, rapid movements of the respiratory tract due to breathing or coughing, and secretions which occur commonly in the bronchi, especially in patients suffering from pulmonary disorders. Methods The use of recorded bronchoscopy video sequences for diagnostic, reference and educational purposes could be considerably extended with efficient, flexible summarization algorithms. Thus, the authors developed a prototype system to create shortcuts (called summaries or abstracts) of bronchoscopy video recordings. Such a system, based on models described in previously published papers, employs image analysis methods to exclude frames or sequences of limited diagnostic or education value. Results The algorithm for the selection or exclusion of specific frames or shots from video sequences recorded during bronchoscopy procedures is based on several criteria, including automatic detection of "non-informative", frames showing the branching of the airways and frames including pathological lesions. Conclusions The paper focuses on the challenge of generating summaries of bronchoscopy video recordings. PMID:22185344

Ethical Considerations for Planetary Protection in Space Exploration: A Workshop

PubMed Central

Rummel, J.D.; Horneck, G.

2012-01-01

Abstract With the recognition of an increasing potential for discovery of extraterrestrial life, a diverse set of researchers have noted a need to examine the foundational ethical principles that should frame our collective space activities as we explore outer space. A COSPAR Workshop on Ethical Considerations for Planetary Protection in Space Exploration was convened at Princeton University on June 8–10, 2010, to examine whether planetary protection measures and practices should be extended to protect planetary environments within an ethical framework that goes beyond “science protection” per se. The workshop had been in development prior to a 2006 NRC report on preventing the forward contamination of Mars, although it responded directly to one of the recommendations of that report and to several peer-reviewed papers as well. The workshop focused on the implications and responsibilities engendered when exploring outer space while avoiding harmful impacts on planetary bodies. Over 3 days, workshop participants developed a set of recommendations addressing the need for a revised policy framework to address “harmful contamination” beyond biological contamination, noting that it is important to maintain the current COSPAR planetary protection policy for scientific exploration and activities. The attendees agreed that there is need for further study of the ethical considerations used on Earth and the examination of management options and governmental mechanisms useful for establishing an environmental stewardship framework that incorporates both scientific input and enforcement. Scientists need to undertake public dialogue to communicate widely about these future policy deliberations and to ensure public involvement in decision making. A number of incremental steps have been taken since the workshop to implement some of these recommendations. Key Words: Planetary protection—Extraterrestrial life—Life in extreme environments—Environment—Habitability. Astrobiology 12, 1017–1023. PMID:23095097

The objective of this article is to describe the key areas of consideration for global/international advanced pharmacy practice experience (G/I APPE) preceptors, students and learning objectives. At the 2013 Annual Meeting of the American Association of Colleges of Pharmacy (AACP), the GPE SIG prepared and presented an initial report on the G/IAPPE initiatives. Round table discussions were conducted at the 2014 AACP Annual Meeting to document GPE SIG member input on key areas in the report. Literature search of PubMed, Google Scholar and EMBASE with keywords was conducted to expand this report. In this paper, considerations related to preceptors and students and learning outcomes are described. Preceptors for G/I APPEs may vary based on the learning outcomes of the experience. Student learning outcomes for G/I APPEs may vary based on the type of experiential site. Recommendations and future directions for development of G/IAPPEs are presented. Development of a successful G/I APPE requires significant planning and consideration of appropriate qualifications for preceptors and students.

2018-05-01

Extended half-life factor products have reduced annualized bleeding rates in hemophilia patients. The impact of extended half-life versus conventional factor products on hemophilia caregiver burden has not been investigated. This study aimed to evaluate caregiver burden in extended half-life versus conventional factor products for hemophilia A and B. This cross-sectional web-based study of caregivers of people with hemophilia A or B was recruited from a panel research company and by word of mouth. Participants completed the Hemophilia Caregiver Impact measure, the PedsQL Family Impact Module (PedsQL), and the Work Productivity and Activity Impairment Questionnaire (WPAI). We also collected demographic, insurance coverage, and medical information related to the hemophilia patient(s). Burden differences were assessed using linear regression and matched cohort analyses. The sample (n = 448) included 49 people who were caring for people on extended half-life factor products. Worse caregiver burden was associated with more infusions per week and more bleeds in the past 6 months. Regression analyses suggested that caring for someone who is on a extended half-life factor product is associated with lower emotional impact (β = - 0.11, p < 0.05, Adjusted R 2  = 0.06), and shows a trend association with lower practical impact (β = - 0.09, p < 0.10, Adjusted R 2  = 0.05). The matched cohort analysis also revealed that people on extended half-life factor product had lower Emotional Impact and Practical Impact scores (t = - 2.95 and - 2.94, respectively, p < 0.05 in both cases). No differences were detected on the PedsQL or the WPAI. The reduced required frequency of factor product infusions of extended half-life factor products appears to reduce the emotional distress and practical burden of caregiving. Future work should evaluate the longitudinal impact.

The diagenetic silica enrichment is colocated with detrital silica enrichment observed in the lacustrine bedrock yet extends into a considerably younger, unconformably draping aeolian sandstone, implying that diagenetic silica enrichment postdates the detrital silica enrichment. A causal connection between the detrital and diagenetic silica enrichment implies that water was present in the subsurface of Gale crater long after deposition of the lacustrine sediments and that it mobilized detrital amorphous silica and precipitated it along fractures in the overlying bedrock. Although absolute timing is uncertain, the observed diagenesis likely represents some of the most recent groundwater activity in Gale crater and suggests that the timescale of potential habitability extended considerably beyond the time that the lacustrine sediments of Aeolis Mons were deposited.

OBJECTIVE To investigate differences in HIV infection- related risk practices by Female Sex Workers according to workplace and the effects of homophily on estimating HIV prevalence. METHODS Data from 2,523 women, recruited using Respondent-Driven Sampling, were used for the study carried out in 10 Brazilian cities in 2008-2009. The study included female sex workers aged 18 and over. The questionnaire was completed by the subjects and included questions on characteristics of professional activity, sexual practices, use of drugs, HIV testing, and access to health services. HIV quick tests were conducted. The participants were classified in two groups according to place of work: on the street or indoor venues, like nightclubs and saunas. To compare variable distributions by place of work, we used Chi-square homogeneity tests, taking into consideration unequal selection probabilities as well as the structure of dependence between observations. We tested the effect of homophily by workplace on estimated HIV prevalence. RESULTS The highest HIV risk practices were associated with: working on the streets, lower socioeconomic status, low regular smear test coverage, higher levels of crack use and higher levels of syphilis serological scars as well as higher prevalence of HIV infection. The effect of homophily was higher among sex workers in indoor venues. However, it did not affect the estimated prevalence of HIV, even after using a post-stratification by workplace procedure. CONCLUSIONS The findings suggest that strategies should focus on extending access to, and utilization of, health services. Prevention policies should be specifically aimed at street workers. Regarding the application of Respondent-Driven Sampling, the sample should be sufficient to estimate transition probabilities, as the network develops more quickly among sex workers in indoor venues.

Spirituality and Aging in Place: The Impact of Extreme Climatic Conditions on Domestic Gardening Practice.

PubMed

Adams, Joanne; Pascal, Jan; Dickson-Swift, Virginia

2014-12-01

There is limited research exploring how domestic water restrictions imposed as a result of drought conditions impact upon the lives of independently living older people. Within this age group (60 years plus), the domestic garden frequently forms an intrinsic component of ongoing health and well-being. Gardening practice offers components of both mental and physical activity and, for many older people, leads to emotional and spiritual connection on a number of levels. The capacity of older people to maintain a garden during a period of water restrictions is greatly reduced, and the resulting impact on health and well-being is considerable. A recent study, conducted in south-eastern Australia, aimed to determine the benefits to health and well-being of maintaining a domestic garden for older people and the impact of water restrictions on garden practice. This occurred at a time following a prolonged period of drought and, in central Victoria, a complete ban on outside watering. In-depth qualitative interviews were conducted with 10 gardeners aged between 60 and 83 who had tended their garden over an extended period. The lived experience of gardening was explored through hermeneutic phenomenological analysis. Clear benefits to health and well-being were established, and yet, the essence of this experience lay in the capacity of gardeners to remain connected to their garden despite change. The crisis imposed by ongoing drought and restricted use of water generated a strong impetus for adaptation, resilience and acceptance of change. The spiritual nature of gardening practice clearly emerged and appeared to intensify the experience of gardening and consolidate adaption to change on a number of levels. © The Author(s) 2015.

Advance directives in the UK: legal, ethical, and practical considerations for doctors.

PubMed

Kessel, A S; Meran, J

1998-05-01

In the United Kingdom (UK), advance directives have recently received considerable attention from professional and voluntary organizations as well as medical journals and the media. However, despite such exposure, many doctors remain uncertain of the importance or relevance of advance directives with regard to their own clinical practice. This paper addresses these uncertainties by first explaining what advance directives are and then describing the current legal status of such directives in the UK. Examination of the cases underpinning this status reveals several key elements: competence, information, anticipation, applicability, and freedom from duress. Each is discussed. Although this paper focuses on legal issues, it is important that medical law does not dominate medical ethics. Accordingly, the paper also discusses some important philosophical and sociological considerations that have remained largely unexplored in the medical press. Finally, the paper deals with practical matters, including how the general practitioner might be involved.

Integrated Modelling - the next steps (Invited)

NASA Astrophysics Data System (ADS)

Moore, R. V.

2010-12-01

Integrated modelling (IM) has made considerable advances over the past decade but it has not yet been taken up as an operational tool in the way that its proponents had hoped. The reasons why will be discussed in Session U17. This talk will propose topics for a research and development programme and suggest an institutional structure which, together, could overcome the present obstacles. Their combined aim would be first to make IM into an operational tool useable by competent public authorities and commercial companies and, in time, to see it evolve into the modelling equivalent of Google Maps, something accessible and useable by anyone with a PC or an iphone and an internet connection. In a recent study, a number of government agencies, water authorities and utilities applied integrated modelling to operational problems. While the project demonstrated that IM could be used in an operational setting and had benefit, it also highlighted the advances that would be required for its widespread uptake. These were: greatly improving the ease with which models could be a) made linkable, b) linked and c) run; developing a methodology for applying integrated modelling; developing practical options for calibrating and validating linked models; addressing the science issues that arise when models are linked; extending the range of modelling concepts that can be linked; enabling interface standards to pass uncertainty information; making the interface standards platform independent; extending the range of platforms to include those for high performance computing; developing the concept of modelling components as web services; separating simulation code from the model’s GUI, so that all the results from the linked models can be viewed through a single GUI; developing scenario management systems so that that there is an audit trail of the version of each model and dataset used in each linked model run. In addition to the above, there is a need to build a set of integrated modelling demonstrations and to achieve a critical mass of accessible linkable models. These models will be spread across the world and there will need to be a search mechanism to find them. If the benefits of integrated modelling are to become widely available, ways will have to be found to automate and hide the linking process. All the above will require considerable resources. It is proposed to build these resources by creating an international community of practice based upon the open source model. The talk will expand upon the research and development required.

Objectives. We examined whether specific antismoking advertising–based beliefs regarding the addictiveness of smoking, the dangers of environmental tobacco smoke, and the tobacco industry’s use of deceptive advertising practices are associated with adult smokers’ consideration of quitting. We also assessed whether interactions between such beliefs and having children living in the home were associated with consideration of quitting. Methods. We used analyses of smokers’ responses to a telephone survey conducted after completion of the Wisconsin Anti-Tobacco Media Campaign to test hypotheses associated with our study objectives. Results. Results indicated that advertising-based beliefs regarding smoking addictiveness and the dangers of environmental tobacco smoke were associated with consideration of quitting. The findings also showed that consideration of quitting was positively affected by the interaction between number of children living at home and advertising-based beliefs about deceptive tobacco industry advertising practices designed to induce people to smoke. Conclusions. Creating advertisements that target specific antismoking beliefs may be the most effective approach to enhancing consideration of quitting among adult smokers, particularly those with children living at home.

The user's mental model is the core guiding theory of product design, especially practical products. The essence of practical product is a tool which is used by users to meet their needs. Then, the most important feature of a tool is usability. The design method based on the user's mental model provides a series of practical and feasible theoretical guidance for improving the usability of the product according to the user's awareness of things. In this paper, we propose a method of designing smartphone interface based on the extended user's mental model according to further research on user groups. This approach achieves personalized customization of smartphone application interface and enhance application using efficiency.

Circumcision: what should be done?

PubMed

Ben-Yami, Hanoch

2013-07-01

I explain why I think that considerations regarding the opposing rights involved in the practice of circumcision-rights of the individual to bodily integrity and rights of the community to practice its religion-would not help us decide on the desirable policy towards this controversial practice. I then suggest a few measures that are not in conflict with either religious or community rights but that can both reduce the harm that circumcision as currently practiced involves and bring about a change in attitude towards the practice, thus further reducing its frequency. These measures are the compulsory administration of anaesthetics; the banning of the metzitzah b'peh; and having an upper age limit of a few months on non-therapeutic circumcision of minors. I conclude with general considerations on why the steps taken towards the reform of circumcision should be moderate.

Hydrotherapy is widely used in burns management however there are risks associated with its use, in particular cross-infection. Data regarding indications and techniques in common use is deficient. This study aimed to investigate hydrotherapy practices in the UK and Ireland. A survey of the hydrotherapy practice of major burn care providers was performed by e mail and where necessary, follow up telephone contact. The survey included 28 burn care providers. 27 reported using hydrotherapy. Only 11 (41%) had defined indication criteria with 4 (15%) implementing a specific protocol. Variations in hydrotherapy practice were seen. Hydrotherapy is used nationwide, however considerable variation in practice exists. One area worthy of further consideration is the need for appropriate standards of infection control. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

Considerations for safe glucocorticoid therapy

PubMed

2018-06-01

Synthetic glucocorticoids have innumerable therapeutic applications and are frequently used in medical practice. Changes in the wide variety of synthetic molecules and the different routes of administration cause differences in anti-inflammatory action, therapeutic action and mineralocorticoid effects. Endocrinologists are generally consulted to evaluate the gradual decline in treatment, rather than to indicate it. We present general information and practical advice to the pediatrician to minimize the adverse effects and considerations to be taken into account for the suspension of treatment.

Consumers' purchase of organic food products. A matter of convenience and reflexive practices.

PubMed

Hjelmar, Ulf

2011-04-01

The aim of this study was to gain insight into the purchase of organic food products by consumers and to explore the main factors driving this process. This paper uses evidence from 16 in-depth interviews with consumers in Denmark carried out in 2008-2009. On the basis of the analysis two broad concepts are suggested: convenience behaviours and reflexive practices. Convenience behaviours are characteristic of pragmatic organic consumers. This type of shopping behaviour requires organic foods to be available in the local supermarket, they have to be clearly visible (preferably with an eco-label), and the price differential vis-à-vis conventional products have to be minimal. The analysis also showed that politically/ethically minded consumers have reflexive practices when purchasing organic food products: health considerations, ethical considerations (animal welfare), political considerations (environmentalism) and quality considerations (taste) play an important part for these consumers. Reflexive shopping practices can be sparked by life events (e.g. having children), "shocking" news about conventional food products and similar events, and news capable of creating a "cognitive dissonance" among consumers. The Danish case illustrates that the government needs to actively implement reforms and promote activities which make organic products a convenient choice for the pragmatic oriented consumer if their market share is to increase substantially.

Using lies, in dementia care, reveals a common practice far beyond the diagnosis and prognosis, extending to the entire care process. In this article, we report results about the attitude and the behaviour of nurses towards the use of lies to patients with dementia. An epidemiological cross-sectional study was conducted between September 2016 and February 2017 in 12 elderly residential facilities and in the geriatric, psychiatric and neurological wards of six specialised hospitals of Italy's Campania Region. In all, 106 nurses compiled an attitude questionnaire (A) where the main question was 'Do you think it is ethically acceptable to use lies to patients with dementia?', instead 106 nurses compiled a behaviour questionnaire (B), where the main question was 'Have you ever used lies to patients with dementia?' Ethical considerations: Using lies in dementia care, although topic ethically still controversial, reveals a common practice far beyond the diagnosis and prognosis, extending to the entire care process. Only a small percentage of the interviewed nurses stated that they never used lies/that it is never acceptable to use lies (behaviour 10.4% and attitude 12.3%; p = 0.66). The situation in which nurses were more oriented to use lies was 'to prevent or reduce aggressive behaviors'. Indeed, only the 6.7% in the attitude group and 3.8% in the behaviour group were against using lies. On the contrary, the case in which the nurses were less oriented to use lies was 'to avoid wasting time giving explanations', in this situation were against using lies the 51.0% of the behaviour group and the 44.6% of the attitude group. Our results, according to other studies, support the hypothesis of a low propensity of nurses to ethical reflection about use of lies. In our country, the implementation of guidelines about a correct use of lie in the relationship between health operators and patients would be desirable.

Adequate caloric intake plays a vital role in the course of illness and the recovery of critically ill patients. Nutritional status and nutrient delivery during critical illness have been linked to clinical outcomes such as mortality, incidence of infection, and length of stay. However, feeding practices with critically ill pediatric patients after cardiac surgery are variable. The Pediatric Cardiac Intensive Care Society sought to provide an expert review on provision of nutrition to pediatric cardiac intensive care patients, including caloric requirements, practical considerations for providing nutrition, safety of enteral nutrition in controversial populations, feeding considerations with chylothorax, and the benefits of feeding beyond nutrition. This article addresses these areas of concern and controversy.

2015-01-01

There is increasing pressure for Australian rural general practices to engage in educational delivery as a means of addressing workforce issues and accommodating substantial increases in learners. For practices that have now developed a strong focus on education, there is the challenge to complement this by engaging in research activity. This study develops a rural academic general practice framework to assist rural practices in developing both comprehensive educational activity and a strong research focus thus moving towards functioning as mature academic units. A case study research design was used with the unit of analysis at the level of the rural general practice. Purposively sampled practices were recruited and individual interviews conducted with staff (supervisors, practice managers, nurses), learners (medical students, interns and registrars) and patients. Three practices hosted 'multi-level learners', two practices hosted one learner group and one had no learners. Forty-four individual interviews were conducted with staff, learners and patients. Audio recordings were transcribed for thematic analysis. After initial inductive coding, deductive analysis was undertaken with reference to recent literature and the expertise of the research team resulting in the rural academic general practice framework. Three key themes emerged with embedded subthemes. For the first theme, organisational considerations, subthemes were values/vision/culture, patient population and clinical services, staffing, physical infrastructure/equipment, funding streams and governance. For the second theme, educational considerations, subthemes were processes, clinical supervision, educational networks and learner presence. Third, for research considerations, there were the subthemes of attitude to research and research activity. The framework maps the development of a rural academic practice across these themes in four progressive stages: beginning, emerging, consolidating and established. The data enabled a framework to be constructed to map rural general practice activity with respect to activity characteristic of an academic general practice. The framework offers guidance to practices seeking to transition towards becoming a mature academic practice. The framework also offers guidance to educational institutions and funding bodies to support the development of academic activity in rural general practices. The strengths and limitations of the study design are outlined.

2018-01-01

ABSTRACT Purpose: Recognising that one way to address the logistical and safety considerations of research conducted in humanitarian emergencies is to use internet communication technologies to facilitate interviews online, this article explores some practical and methodological considerations inherent to qualitative online interviewing. Method: Reflections from a case study of a multi-site research project conducted in post-conflict countries are presented.  Synchronous online cross-language qualitative interviews were conducted in one country.  Although only a small proportion of interviews were conducted online (six out of 35), it remains important to critically consider the impact upon data produced in this way. Results: A range of practical and methodological considerations are discussed, illustrated with examples.  Results suggest that whilst online interviewing has methodological and ethical potential and versatility, there are inherent practical challenges in settings with poor internet and electricity infrastructure.  Notable methodological limitations include barriers to building rapport due to partial visual and non-visual cues, and difficulties interpreting pauses or silences. Conclusions: Drawing upon experiences in this case study, strategies for managing the practical and methodological limitations of online interviewing are suggested, alongside recommendations for supporting future research practice.  These are intended to act as a springboard for further reflection, and operate alongside other conceptual frameworks for online interviewing.

Shim, Woochan S; Nelson-Becker, Holly

2009-01-01

While literature on elder abuse has expanded, elder abuse by intimate partners has been less investigated. Even less is known about intimate partner violence among older Koreans living in North America. This article identifies important cultural considerations for individuals helping the Korean older adult community, beginning with the definition of intimate partner violence in this community and barriers to leaving that include traditional views of the East Asian self. Current practice interventions are discussed and recommendations for future practice such as healing han, the accumulated suffering from years of abuse, are suggested. The ultimate goal of this paper is to expand awareness in order to develop the best culturally competent prevention and intervention practice for Korean older intimate partner violence survivors in North America.

Extending the Host Range of Bacteriophage Particles for DNA Transduction.

PubMed

Yosef, Ido; Goren, Moran G; Globus, Rea; Molshanski-Mor, Shahar; Qimron, Udi

2017-06-01

A major limitation in using bacteriophage-based applications is their narrow host range. Approaches for extending the host range have focused primarily on lytic phages in hosts supporting their propagation rather than approaches for extending the ability of DNA transduction into phage-restrictive hosts. To extend the host range of T7 phage for DNA transduction, we have designed hybrid particles displaying various phage tail/tail fiber proteins. These modular particles were programmed to package and transduce DNA into hosts that restrict T7 phage propagation. We have also developed an innovative generalizable platform that considerably enhances DNA transfer into new hosts by artificially selecting tails that efficiently transduce DNA. In addition, we have demonstrated that the hybrid particles transduce desired DNA into desired hosts. This study thus critically extends and improves the ability of the particles to transduce DNA into novel phage-restrictive hosts, providing a platform for myriad applications that require this ability.

Rather than a rigorous mathematical treatment, the goal of this paper is to build intuition about what assumptions are implicit in the use of the Lomb–Scargle periodogram and related estimators of periodicity, so as to motivate important practical considerations required in its proper application and interpretation.

Childsmile is Scotland's national child oral health improvement programme. To support the delivery of prevention in general dental practice in keeping with clinical guidelines, Childsmile sought accreditation for extended duty training for dental nurses to deliver clinical preventive care. This approach has allowed extended duty dental nurses (EDDNs) to take on roles traditionally undertaken by general dental practitioners (GDPs). While skill-mix approaches have been found to work well in general medicine, they have not been formally evaluated in dentistry. Understanding the factors which influence nurses' ability to fully deliver their extended roles is necessary to ensure nurses' potential is reached and that children receive preventive care in line with clinical guidance in a cost-effective way. This paper investigates the supplementation of GDPs' roles by EDDNs, in general dental practice across Scotland. A cross-sectional postal survey aiming to reach all EDDNs practising in general dental practice in Scotland was undertaken. The survey measured nurses': role satisfaction, perceived utility of training, frequency, and potential behavioural mediators of, preventive delivery. Frequencies, correlations and multi-variable linear regression were used to analyse the data. Seventy-three percent of practices responded with 174 eligible nurses returning questionnaires. Respondents reported a very high level of role satisfaction and the majority found their training helpful in preparing them for their extended role. While a high level of preventive delivery was reported, fluoride vanish (FV) was delivered less frequently than dietary advice (DA), or oral hygiene advice (OHA). Delivering FV more frequently was associated with higher role satisfaction (p < 0.001). Those nurses who had been practising longer reported delivering FV less frequently than those more recently qualified (p < 0.001). Perceived difficulty of delivering preventive care (skills) and motivation to do so were most strongly associated with frequency of delivery (p < 0.001 for delivery of FV, DA and OHA). This study has provided insight into EDDNs' experiences and demonstrates that with appropriate training and support, EDDNs can supplement GDPs' roles in general dental practice in Scotland. However, some barriers to delivery were identified with delivery of FV showing scope for improvement.

Vital Involvement Practice: strengths as more than tools for solving problems.

PubMed

Kivnick, Helen Q; Stoffel, Sharon A

2005-01-01

This article describes Vital Involvement Practice, a strength-based approach to clinical practice with elders, including those who are extremely frail. Using this approach, practitioners have been able to help elders increase later-life vitality and associated positive quality of life through: (1) systematic identification of individual strengths and assets (found both in the person and in the surrounding environment), and (2) consideration of these strengths alongside the individual and environmental deficits that are the subject of most geriatric practice. The approach utilizes original data-gathering tools (Occupational Profile; Life Strengths Interview Guide) and a stepwise, worksheet- structured consideration of these data in order to formulate action strategies for achieving client goals (Domain Scan; Domain Goals; Life Plan/Strategy). All elements of VIP emerged in pilot work with gerontological practitioners and their elder clients in such settings as: primary health care; government social service; subsidized senior housing; private clinical practice; community recreation. Limitations, implications, and promise are noted, with respect to practice and research.

Guidance, Navigation and Control (GN&C): Best Practices for Human-Rated Spacecraft Systems

NASA Technical Reports Server (NTRS)

Lebsock, Ken; West, John

2008-01-01

In 2007 the NESC completed an in-depth assessment to identify, define and document engineering considerations for the Design Development Test and Evaluation (DDT&E) of human-rated spacecraft systems. This study had been requested by the Astronaut Office at JSC to help them to better understand what is required to ensure safe, robust, and reliable human-rated spacecraft systems. The 22 GN&C engineering Best Practices described in this paper are a condensed version of what appears in the NESC Technical Report. These Best Practices cover a broad range from fundamental system architectural considerations to more specific aspects (e.g., stability margin recommendations) of GN&C system design and development. 15 of the Best Practices address the early phases of a GN&C System development project and the remaining 7 deal with the later phases. Some of these Best Practices will cross-over between both phases. We recognize that this set of GN&C Best Practices will not be universally applicable to all projects and mission applications.

Attributes of innovations and approaches to scalability - lessons from a national program to extend the scope of practice of health professionals.

PubMed

Masso, Malcolm; Thompson, Cristina

2016-01-01

The context for the paper was the evaluation of a national program in Australia to investigate extended scopes of practice for health professionals (paramedics, physiotherapists, and nurses). The design of the evaluation involved a mixed-methods approach with multiple data sources. Four multidisciplinary models of extended scope of practice were tested over an 18-month period, involving 26 organizations, 224 health professionals, and 36 implementation sites. The evaluation focused on what could be learned to inform scaling up the extended scopes of practice on a national scale. The evaluation findings were used to develop a conceptual framework for use by clinicians, managers, and policy makers to determine appropriate strategies for scaling up effective innovations. Development of the framework was informed by the literature on the diffusion of innovations, particularly an understanding that certain attributes of innovations influence adoption. The framework recognizes the role played by three groups of stakeholders: evidence producers, evidence influencers, and evidence adopters. The use of the framework is illustrated with four case studies from the evaluation. The findings demonstrate how the scaling up of innovations can be influenced by three quite distinct approaches - letting adoption take place in an uncontrolled, unplanned, way; actively helping the process of adoption; or taking deliberate steps to ensure that adoption takes place. Development of the conceptual framework resulted in two sets of questions to guide decisions about scalability, one for those considering whether to adopt the innovation (evidence adopters), and the other for those trying to decide on the optimal strategy for dissemination (evidence influencers).

From mandatory to voluntary testing: balancing human rights, religious and cultural values, and HIV/AIDS prevention in Ghana.

PubMed

Luginaah, Isaac N; Yiridoe, Emmanuel K; Taabazuing, Mary-Margaret

2005-10-01

This paper examines efforts by some churches in Ghana to reduce the spread of HIV/AIDS. The analysis is based on focus group discussions with two groups of men and two groups of women, along with in-depth interviews with 13 pastors and marriage counsellors in the churches studied. In response to government and public criticisms about human rights violations, churches that previously imposed mandatory HIV testing on members planning to marry now have voluntary testing programmes. However, the results suggest that what the churches refer to as voluntary testing may not be truly voluntary. Cultural values and traditional practices, including traditional courtship and marriage rites (which are performed before church weddings), not only clash with considerations about pre-marital HIV testing but also complicate the contentious issue of confidentiality of information on HIV testing. Associated with these complexities and issues of confidentiality is a reluctance among participants, particularly those from northern Ghana, to test for HIV. The results reveal how broader social impacts of HIV testing for those planning to marry may extend beyond individuals or couples in different cultural contexts. The findings also support the general view that there are no perfect or easy solutions to combating the HIV/AIDS pandemic. Practical solutions and programs for Ghana cannot be neutral to cultural values and need to be tailored for particular (ethnic) populations.

Real-space finite-difference approach for multi-body systems: path-integral renormalization group method and direct energy minimization method.

PubMed

Sasaki, Akira; Kojo, Masashi; Hirose, Kikuji; Goto, Hidekazu

2011-11-02

The path-integral renormalization group and direct energy minimization method of practical first-principles electronic structure calculations for multi-body systems within the framework of the real-space finite-difference scheme are introduced. These two methods can handle higher dimensional systems with consideration of the correlation effect. Furthermore, they can be easily extended to the multicomponent quantum systems which contain more than two kinds of quantum particles. The key to the present methods is employing linear combinations of nonorthogonal Slater determinants (SDs) as multi-body wavefunctions. As one of the noticeable results, the same accuracy as the variational Monte Carlo method is achieved with a few SDs. This enables us to study the entire ground state consisting of electrons and nuclei without the need to use the Born-Oppenheimer approximation. Recent activities on methodological developments aiming towards practical calculations such as the implementation of auxiliary field for Coulombic interaction, the treatment of the kinetic operator in imaginary-time evolutions, the time-saving double-grid technique for bare-Coulomb atomic potentials and the optimization scheme for minimizing the total-energy functional are also introduced. As test examples, the total energy of the hydrogen molecule, the atomic configuration of the methylene and the electronic structures of two-dimensional quantum dots are calculated, and the accuracy, availability and possibility of the present methods are demonstrated.

A note on probabilistic models over strings: the linear algebra approach.

PubMed

Bouchard-Côté, Alexandre

2013-12-01

Probabilistic models over strings have played a key role in developing methods that take into consideration indels as phylogenetically informative events. There is an extensive literature on using automata and transducers on phylogenies to do inference on these probabilistic models, in which an important theoretical question is the complexity of computing the normalization of a class of string-valued graphical models. This question has been investigated using tools from combinatorics, dynamic programming, and graph theory, and has practical applications in Bayesian phylogenetics. In this work, we revisit this theoretical question from a different point of view, based on linear algebra. The main contribution is a set of results based on this linear algebra view that facilitate the analysis and design of inference algorithms on string-valued graphical models. As an illustration, we use this method to give a new elementary proof of a known result on the complexity of inference on the "TKF91" model, a well-known probabilistic model over strings. Compared to previous work, our proving method is easier to extend to other models, since it relies on a novel weak condition, triangular transducers, which is easy to establish in practice. The linear algebra view provides a concise way of describing transducer algorithms and their compositions, opens the possibility of transferring fast linear algebra libraries (for example, based on GPUs), as well as low rank matrix approximation methods, to string-valued inference problems.

Among the fundamental evolutionary forces, recombination arguably has the largest impact on the practical work of plant breeders. Varying over 1,000-fold across the maize genome, the local meiotic recombination rate limits the resolving power of quantitative trait mapping and the precision of favorable allele introgression. The consequences of low recombination also theoretically extend to the species-wide scale by decreasing the power of selection relative to genetic drift, and thereby hindering the purging of deleterious mutations. In this study, we used genotyping-by-sequencing (GBS) to identify 136,000 recombination breakpoints at high resolution within US and Chinese maize nested association mapping populations. We find that the pattern of cross-overs is highly predictable on the broad scale, following the distribution of gene density and CpG methylation. Several large inversions also suppress recombination in distinct regions of several families. We also identify recombination hotspots ranging in size from 1 kb to 30 kb. We find these hotspots to be historically stable and, compared with similar regions with low recombination, to have strongly differentiated patterns of DNA methylation and GC content. We also provide evidence for the historical action of GC-biased gene conversion in recombination hotspots. Finally, using genomic evolutionary rate profiling (GERP) to identify putative deleterious polymorphisms, we find evidence for reduced genetic load in hotspot regions, a phenomenon that may have considerable practical importance for breeding programs worldwide.

Fisher, Elliott S.; Staiger, Douglas O.; Bynum, Julie P.W.; Gottlieb, Daniel J.

2007-01-01

Many current policies and approaches to performance measurement and payment reform focus on individual providers; they risk reinforcing the fragmented care and lack of coordination experienced by patients with serious illness. In this paper we show that Medicare beneficiaries receive most of their care from relatively coherent local delivery systems comprising physicians and the hospitals where they work or admit their patients. Efforts to create accountable care organizations at this level—the extended hospital medical staff—deserve consideration as a potential means of improving the quality and lowering the cost of care.

Localized-to-extended-states transition below the Fermi level

NASA Astrophysics Data System (ADS)

Tito, M. A.; Pusep, Yu. A.

2018-05-01

Time-resolved photoluminescence is employed to examine a transition from localized to extended electron states below the Fermi level in multiple narrow quantum well GaAs/AlGaAs heterostructures, where disorder was generated by interface roughness. Such a transition resembles the metal-insulator transition profoundly investigated by electric transport measurements. An important distinction distinguishes the localized-to-extended-states transition studied here: it takes place below the Fermi level in an electron system with a constant concentration, which implies unchanging Coulomb correlations. Moreover, for such a localized-to-extended-states transition the temperature is shown to be irrelevant. In the insulating regime the magnetic field was found to cause an additional momentum relaxation which considerably enhanced the recombination rate. Thus, we propose a method to explore the evolution of the localized electron states in a system with a fixed disorder and Coulomb interaction.

Flight evaluation of an extended engine life mode on an F-15 airplane

Myers, Lawrence P.; Conners, Timothy R.

1992-01-01

An integrated flight and propulsion control system designed to reduce the rate of engine deterioration was developed and evaluated in flight on the NASA Dryden F-15 research aircraft. The extended engine life mode increases engine pressure ratio while reducing engine airflow to lower the turbine temperature at constant thrust. The engine pressure ratio uptrim is modulated in real time based on airplane maneuver requirements, flight conditions, and engine information. The extended engine life mode logic performed well, significantly reducing turbine operating temperature. Reductions in fan turbine inlet temperature of up to 80 F were obtained at intermediate power and up to 170 F at maximum augmented power with no appreciable loss in thrust. A secondary benefit was the considerable reduction in thrust-specific fuel consumption. The success of the extended engine life mode is one example of the advantages gained from integrating aircraft flight and propulsion control systems.

2017-03-01

While studies of home-based care delivered by teams led by primary care providers have shown cost savings, little is known about outcomes when practice-extender teams-that is, teams led by registered nurses or lay health workers-provide home visits with similar components (for example, care coordination and education). We evaluated findings from five models funded by Health Care Innovation Awards of the Centers for Medicare and Medicaid Services. Each model used a mix of different components to strengthen connections to primary care among fee-for-service Medicare beneficiaries with multiple chronic conditions; these connections included practice-extender home visits. Two models achieved significant reductions in Medicare expenditures, and three models reduced utilization in the form of emergency department visits, hospitalizations, or both for beneficiaries relative to comparators. These findings present a strong case for the potential value of home visits by practice-extender teams to reduce Medicare expenditures and service use in a particularly vulnerable and costly segment of the Medicare population.

Ownership of mobile phones is on the rise, a trend in uptake that transcends age, region, race, and ethnicity, as well as income. It is precisely the emerging ubiquity of mobile phones that has sparked enthusiasm regarding their capacity to increase the reach and impact of health care, including mental health care. Community-based clinicians charged with transporting evidence-based interventions beyond research and training clinics are in turn, ideally and uniquely situated to capitalize on mobile phone uptake and functionality to bridge the efficacy to effectiveness gap. As such, this article delineates key considerations to guide these frontline clinicians in mobile phone-enhanced clinical practice, including an overview of industry data on the uptake of and evolution in the functionality of mobile phone platforms, conceptual considerations relevant to the integration of mobile phones into practice, representative empirical illustrations of mobile-phone enhanced assessment and treatment, and practical considerations relevant to ensuring the feasibility and sustainability of such an approach.

Actinic keratosis (AK) affects millions of people worldwide, and its prevalence continues to increase. AK lesions are caused by chronic ultraviolet radiation exposure, and the presence of two or more AK lesions along with photodamage should raise the consideration of a diagnosis of field cancerization. Effective treatment of individual lesions as well as field cancerization is essential for good long-term outcomes. The Swiss Registry of Actinic Keratosis Treatment (REAKT) Working Group has developed clinical practice guidelines for the treatment of field cancerization in patients who present with AK. These guidelines are intended to serve as a resource for physicians as to the most appropriate treatment and management of AK and field cancerization based on current evidence and the combined practical experience of the authors. Treatment of AK and field cancerization should be driven by consideration of relevant patient, disease, and treatment factors, and appropriate treatment decisions will differ from patient to patient. Prevention measures and screening recommendations are discussed, and special considerations related to management of immunocompromised patients are provided.

Schmit, David T

2010-01-01

Contemporary interest in Asian meditation raises questions about when Westerners began investigating these practices. A synopsis of Western-originating scientific meditation research is followed by a brief introduction to mesmerism. Next, the unappreciated ways the mesmerists explored Oriental mind powers is recounted. How the mesmerists' cultural positioning, philosophy, and interest in mind-body practices facilitated their inquiries of Oriental medicine and Hindu contemplative practices is explored, followed by a consideration of why these investigations were unique for the era. The way this work subverted Western cultural imperialism is examined. A consideration of the historical continuities and discontinuities between the mesmerists' inquiries and twentieth-century meditation research concludes the article.

2015-04-01

General practice is becoming increasingly complex due to an ageing population with multiple morbidities and the shift of services from secondary to primary care, yet GP training remains largely the same. Extended training is now recommended, initially proposed as a fourth GP specialty trainee year, but more recently as a broad-based 4-year specialty training programme. To explore the views of newly-qualified GPs about their training and preparedness for specific aspects of the GP's role. Qualitative study with newly-qualified GPs who qualified with Severn Deanery between 2007 and 2010. Semi-structured interviews with 18 GPs between November 2011 and April 2012. Gaining experience in a variety of primary care environments widens insight into patient populations as well as helping GPs develop adaptability and confidence, although this is not routinely part of GP training. However, alongside variety, having continuity with patients in practice remains important. Opportunities to be involved in the management of a practice or to take on substantial leadership roles also vary widely and this may limit preparedness and development of generalist skills. Extended training could help prepare GPs for the current challenges of general practice. It could ensure all trainees are exposed to a greater variety of primary care settings including those outside GP practice, as well as experience of business, finance, and leadership roles. Collectively, these changes have the potential to produce GPs with both generalist and enhanced skills, who are better prepared to work collaboratively across the organisational boundaries between primary, secondary, and community care. © British Journal of General Practice 2015.

Health care systems are increasing efforts to minimize postoperative hospital stays to improve resource use. Common explanations for extended postoperative stay are baseline patient sickness, postoperative complications, or physician practice differences. However, the degree to which extended length of stay (LOS) represents patient illness or postoperative complications remains unknown. The aim is to investigate the influence of postoperative complications and elderly patient comorbidities on extended LOS after anterior cervical discectomy and fusion. This retrospective study was performed from January 1, 2008, to December 31, 2014, on data from the American College of Surgeons National Surgical Quality Improvement Program. Patient demographics, comorbidities, LOS, and inpatient complications were recorded. Multivariable logistic regression analysis was used to determine the odds ratio for risk-adjusted extended LOS. The primary outcome was the degree extended LOS represented patient illness or postoperative complications. Of 4730 participants, 1351 (28.56%) had extended LOS. A minority of patients with extended LOS had a history of relevant comorbidities-diabetes (29.53%), chronic obstructive pulmonary disease (9.4%), congestive heart failure (1.04%), myocardial infarction (0.33%), acute renal failure (0.3%), and stroke (5.92%). Among patients with normal LOS, 96.8% had no complications, 2.7% had 1 complication, and 0.5% had greater than 1 complication. In patients with extended LOS, 79.4% had no complications, 14.5% had 1 complication, and 6.1% had greater than 1 complication (P < 0.0001). Our study suggests much of LOS variation after an anterior cervical discectomy and fusion is not attributable to baseline patient illness or complications and most likely represents differences in practice style or surgeon preference.

Radiology Physician Extenders: A Literature Review of the History and Current Roles of Physician Extenders in Medical Imaging.

Sanders, Vicki L; Flanagan, Jennifer

2015-01-01

The purpose of the literature review was to assess the origins of radiology physician extenders and examine the current roles found in the literature of advanced practice physician extenders within medical imaging. Twenty-six articles relating to physician assistants (PAs), nurse practitioners (NPs), radiologist assistants (RAs), and nuclear medicine advanced associates (NMAAs) were reviewed to discern similarities and differences in history, scope of practice, and roles in the medical imaging field. The literature showed PAs and NPs are working mostly in interventional radiology. PAs, NPs, and RAs perform similar tasks in radiology, including history and physicals, evaluation and management, preprocedure work-up, obtaining informed consent, initial observations/reports, and post-procedure follow-up. NPs and PAs perform a variety of procedures but most commonly vascular access, paracentesis, and thoracentesis. RAs perform gastrointestinal, genitourinary, nonvascular invasive fluoroscopy procedures, and vascular access procedures. The review revealed NMAAs are working in an advanced role, but no specific performances of procedures was found in the literature, only suggested tasks and clinical competencies. PAs, NPs, and RAs are currently the three main midlevel providers used in medical imaging. These midlevel providers are being used in a variety of ways to increase the efficiency of the radiologist and provide diagnostic and therapeutic radiologic procedures to patients. NMAAs are being used in medical imaging but little literature is available on current roles in clinical practice. More research is needed to assess the exact procedures and duties being performed by these medical imaging physician extenders.

A Framework for Understanding Physics Students' Computational Modeling Practices

NASA Astrophysics Data System (ADS)

Lunk, Brandon Robert

With the growing push to include computational modeling in the physics classroom, we are faced with the need to better understand students' computational modeling practices. While existing research on programming comprehension explores how novices and experts generate programming algorithms, little of this discusses how domain content knowledge, and physics knowledge in particular, can influence students' programming practices. In an effort to better understand this issue, I have developed a framework for modeling these practices based on a resource stance towards student knowledge. A resource framework models knowledge as the activation of vast networks of elements called "resources." Much like neurons in the brain, resources that become active can trigger cascading events of activation throughout the broader network. This model emphasizes the connectivity between knowledge elements and provides a description of students' knowledge base. Together with resources resources, the concepts of "epistemic games" and "frames" provide a means for addressing the interaction between content knowledge and practices. Although this framework has generally been limited to describing conceptual and mathematical understanding, it also provides a means for addressing students' programming practices. In this dissertation, I will demonstrate this facet of a resource framework as well as fill in an important missing piece: a set of epistemic games that can describe students' computational modeling strategies. The development of this theoretical framework emerged from the analysis of video data of students generating computational models during the laboratory component of a Matter & Interactions: Modern Mechanics course. Student participants across two semesters were recorded as they worked in groups to fix pre-written computational models that were initially missing key lines of code. Analysis of this video data showed that the students' programming practices were highly influenced by their existing physics content knowledge, particularly their knowledge of analytic procedures. While this existing knowledge was often applied in inappropriate circumstances, the students were still able to display a considerable amount of understanding of the physics content and of analytic solution procedures. These observations could not be adequately accommodated by the existing literature of programming comprehension. In extending the resource framework to the task of computational modeling, I model students' practices in terms of three important elements. First, a knowledge base includes re- sources for understanding physics, math, and programming structures. Second, a mechanism for monitoring and control describes students' expectations as being directed towards numerical, analytic, qualitative or rote solution approaches and which can be influenced by the problem representation. Third, a set of solution approaches---many of which were identified in this study---describe what aspects of the knowledge base students use and how they use that knowledge to enact their expectations. This framework allows us as researchers to track student discussions and pinpoint the source of difficulties. This work opens up many avenues of potential research. First, this framework gives researchers a vocabulary for extending Resource Theory to other domains of instruction, such as modeling how physics students use graphs. Second, this framework can be used as the basis for modeling expert physicists' programming practices. Important instructional implications also follow from this research. Namely, as we broaden the use of computational modeling in the physics classroom, our instructional practices should focus on helping students understand the step-by-step nature of programming in contrast to the already salient analytic procedures.

Noise Considerations for V/STOL Transports

NASA Technical Reports Server (NTRS)

Kenyon, George C.

1968-01-01

Noise consideration may well be as important a factor in future aircraft concept selection as such economic factors as operating cost and profitability. The impact of noise on some of the design and operational aspects of future V/STOL transports is examined in detail, including consideration of configuration, attitude-control system, lift system, and terminal flight pattern. Extended vertical rise of VTOL aircraft as a method of limiting the intense noise exposure to the terminal area is shown to be only partially effective as well as costly. Comparisons are made of noise contours for conceptual V/STOL transports for several PNdB criteria. The variation in extent of affected area with configuration and criterion emphasizes the importance of establishing an "acceptable" noise level for "city-center" operation.

Assessing the risk of recurrent venous thromboembolism--a practical approach.

PubMed

Fahrni, Jennifer; Husmann, Marc; Gretener, Silvia B; Keo, Hong H

2015-01-01

Recurrent venous thromboembolism (VTE) is associated with increased morbidity and mortality. This risk is lowered by anticoagulation, with a large effect in the initial phase following the venous thromboembolic event, and with a smaller effect in terms of secondary prevention of recurrence when extended anticoagulation is performed. On the other hand, extended anticoagulation is associated with an increased risk of major bleeding and thus leads to morbidity and mortality. Therefore, it is necessary to assess the risk of recurrence for VTE on an individual basis, and a recommendation for secondary prophylaxis should be specifically based on risk calculation of recurrence of VTE and bleeding. In this review, we provide a comprehensive summary of relevant risk factors for recurrent VTE and a practical approach for assessing the risk of recurrence in daily practice.

Collegiality and commerce: The culture of consideration amongst engineers

NASA Astrophysics Data System (ADS)

Nugent, Paul David

This study is a participant observation ethnography of engineering relationships at a defense contracting plant that specializes in the design and manufacture of launch control systems for nuclear submarines. "Consideration" is presented as a unique mode of interaction enabling resource exchange and pivotal in developing and strengthening work relationships. Consideration differs from other modes of exchange such as markets, gift-giving, and charity primarily in that the bestowal of the resource involves little sacrifice. The manner in which consideration is enacted by the engineers, the structural and cultural conditions supporting consideration, and the social and economic consequences of consideration are presented. From these findings it is concluded that consideration is a unique form of economic exchange embedded in concrete relationships that forces us to rethink and extend current conceptualizations of trust, networks, social capital, and friendship in the workplace. The data for the analysis were drawn from twenty interviews and fieldnotes collected and transcribed over a twelve month period. Quotations from the interviews and exerpts from the fieldnotes are included to illustrate claims being made in the analysis as well as to familiarize the reader with the culture developed by engineers and managers in a defense contracting plant.

Web-based recruitment: effects of information, organizational brand, and attitudes toward a Web site on applicant attraction.

PubMed

Allen, David G; Mahto, Raj V; Otondo, Robert F

2007-11-01

Recruitment theory and research show that objective characteristics, subjective considerations, and critical contact send signals to prospective applicants about the organization and available opportunities. In the generating applicants phase of recruitment, critical contact may consist largely of interactions with recruitment sources (e.g., newspaper ads, job fairs, organization Web sites); however, research has yet to fully address how all 3 types of signaling mechanisms influence early job pursuit decisions in the context of organizational recruitment Web sites. Results based on data from 814 student participants searching actual organization Web sites support and extend signaling and brand equity theories by showing that job information (directly) and organization information (indirectly) are related to intentions to pursue employment when a priori perceptions of image are controlled. A priori organization image is related to pursuit intentions when subsequent information search is controlled, but organization familiarity is not, and attitudes about a recruitment source also influence attraction and partially mediate the effects of organization information. Theoretical and practical implications for recruitment are discussed. (c) 2007 APA

Life-cycle assessment of municipal solid waste management alternatives with consideration of uncertainty: SIWMS development and application.

PubMed

Hanandeh, Ali El; El-Zein, Abbas

2010-05-01

This paper describes the development and application of the Stochastic Integrated Waste Management Simulator (SIWMS) model. SIWMS provides a detailed view of the environmental impacts and associated costs of municipal solid waste (MSW) management alternatives under conditions of uncertainty. The model follows a life-cycle inventory approach extended with compensatory systems to provide more equitable bases for comparing different alternatives. Economic performance is measured by the net present value. The model is verified against four publicly available models under deterministic conditions and then used to study the impact of uncertainty on Sydney's MSW management 'best practices'. Uncertainty has a significant effect on all impact categories. The greatest effect is observed in the global warming category where a reversal of impact direction is predicted. The reliability of the system is most sensitive to uncertainties in the waste processing and disposal. The results highlight the importance of incorporating uncertainty at all stages to better understand the behaviour of the MSW system. Copyright (c) 2010 Elsevier Ltd. All rights reserved.

Extending the Reach of Evidence-Based Medicine: A Proposed Categorization of Lower-Level Evidence.

PubMed

Detterbeck, Frank C; Gould, Michael K; Lewis, Sandra Zelman; Patel, Sheena

2018-02-01

Clinical practice involves making many treatment decisions for which only limited formal evidence exists. While the methodology of evidence-based medicine (EBM) has evolved tremendously, there is a need to better characterize lower-level evidence. This should enhance the ability to appropriately weigh the evidence against other considerations, and counter the temptation to think it is more robust than it actually is. A framework to categorize lower-level evidence is proposed, consisting of nonrandomized comparisons, extrapolation using indirect evidence, rationale, and clinical experience (ie, an accumulated general impression). Subtypes are recognized within these categories, based on the degree of confounding in nonrandomized comparisons, the uncertainty involved in extrapolation from indirect evidence, and the plausibility of a rationale. Categorizing the available evidence in this way can promote a better understanding of the strengths and limitations of using such evidence as the basis for treatment decisions in clinically relevant areas that are devoid of higher-level evidence.

Digital simulation of scalar optical diffraction: revisiting chirp function sampling criteria and consequences.

PubMed

Voelz, David G; Roggemann, Michael C

2009-11-10

Accurate simulation of scalar optical diffraction requires consideration of the sampling requirement for the phase chirp function that appears in the Fresnel diffraction expression. We describe three sampling regimes for FFT-based propagation approaches: ideally sampled, oversampled, and undersampled. Ideal sampling, where the chirp and its FFT both have values that match analytic chirp expressions, usually provides the most accurate results but can be difficult to realize in practical simulations. Under- or oversampling leads to a reduction in the available source plane support size, the available source bandwidth, or the available observation support size, depending on the approach and simulation scenario. We discuss three Fresnel propagation approaches: the impulse response/transfer function (angular spectrum) method, the single FFT (direct) method, and the two-step method. With illustrations and simulation examples we show the form of the sampled chirp functions and their discrete transforms, common relationships between the three methods under ideal sampling conditions, and define conditions and consequences to be considered when using nonideal sampling. The analysis is extended to describe the sampling limitations for the more exact Rayleigh-Sommerfeld diffraction solution.

PBIS Is (Not) Behavior Analysis: a Response to Horner and Sugai (2015).

Loukus, Amy K

2015-05-01

I comment on Horner's and Sugai's article regarding the lessons learned from implementing Positive Behavioral Interventions and Support (PBIS)-that is, the things to consider when attempting to extend other works in behavior analysis to the likes of mainstream society. In adopting a critical eye toward the PBIS model, I comment first on the need for dissemination of behavioral principles to a public audience, and then outline the suggestions made by the authors for enhancing acceptance across disciplines. I clarify the definition of PBIS presented by the authors, and summarize the benefits and drawbacks associated with the conceptual argument surrounding the contention that PBIS is a behavior analytic approach to system-wide change, and argue instead for the distinction of elements in the PBIS model and their respective empirical effectiveness. I refer to other works in behavior analysis that are relevant to the current discussion and offer additional considerations for behavior analysts interested in forging ahead with endeavors that aim increase dissemination, particularly those that incorporate a culmination of alternative professional practices.

Drosophila Melanogaster Mitochondrial DNA: Gene Organization and Evolutionary Considerations

PubMed Central

Garesse, R.

1988-01-01

The sequence of a 8351-nucleotide mitochondrial DNA (mtDNA) fragment has been obtained extending the knowledge of the Drosophila melanogaster mitochondrial genome to 90% of its coding region. The sequence encodes seven polypeptides, 12 tRNAs and the 3' end of the 16S rRNA and CO III genes. The gene organization is strictly conserved with respect to the Drosophila yakuba mitochondrial genome, and different from that found in mammals and Xenopus. The high A + T content of D. melanogaster mitochondrial DNA is reflected in a reiterative codon usage, with more than 90% of the codons ending in T or A, G + C rich codons being practically absent. The average level of homology between the D. melanogaster and D. yakuba sequences is very high (roughly 94%), although insertion and deletions have been detected in protein, tRNA and large ribosomal genes. The analysis of nucleotide changes reveals a similar frequency for transitions and transversions, and reflects a strong bias against G+C on both strands. The predominant type of transition is strand specific. PMID:3130291

Microarray Data Processing Techniques for Genome-Scale Network Inference from Large Public Repositories.

Chockalingam, Sriram; Aluru, Maneesha; Aluru, Srinivas

2016-09-19

Pre-processing of microarray data is a well-studied problem. Furthermore, all popular platforms come with their own recommended best practices for differential analysis of genes. However, for genome-scale network inference using microarray data collected from large public repositories, these methods filter out a considerable number of genes. This is primarily due to the effects of aggregating a diverse array of experiments with different technical and biological scenarios. Here we introduce a pre-processing pipeline suitable for inferring genome-scale gene networks from large microarray datasets. We show that partitioning of the available microarray datasets according to biological relevance into tissue- and process-specific categories significantly extends the limits of downstream network construction. We demonstrate the effectiveness of our pre-processing pipeline by inferring genome-scale networks for the model plant Arabidopsis thaliana using two different construction methods and a collection of 11,760 Affymetrix ATH1 microarray chips. Our pre-processing pipeline and the datasets used in this paper are made available at http://alurulab.cc.gatech.edu/microarray-pp.

A review of the literature: the economic impact of preventive dental hygiene services.

PubMed

Sharon, Stull C; Connolly, Irene M; Murphree, Kellie R

2005-01-01

The contributions of dental hygiene as a discipline of prevention, the inception of systemic fluoride in community water systems, the continual research conducted by the National Institute of Dental and Craniofacial Research (NIDCR), and the success of dental sealants have all contributed to the decrease in incidences of dental diseases. The prevalence of employer-based dental insurance must also be recognized as contributing to a substantial paradigm shift on the utilization of oral health preventive services. This review of the economic impact of oral health preventive services on the consumer and the private dental practice suggests that these services have had a significant impact. Dentistry's challenge remains to extend these considerable gains in oral health status to the 150 million U.S. citizens who do not have access to oral health care services identified in the 2000 Oral Health in America: A Report of the Surgeon General. Utilizing preventive, therapeutic, and educational aspects of dental hygiene services, reaching communities without fluoridation of the public water supply, and incorporating mass pediatric dental sealant programs analogous to immunization programs would improve the oral health status of underserved populations.

Automatic query formulations in information retrieval.

PubMed

Salton, G; Buckley, C; Fox, E A

1983-07-01

Modern information retrieval systems are designed to supply relevant information in response to requests received from the user population. In most retrieval environments the search requests consist of keywords, or index terms, interrelated by appropriate Boolean operators. Since it is difficult for untrained users to generate effective Boolean search requests, trained search intermediaries are normally used to translate original statements of user need into useful Boolean search formulations. Methods are introduced in this study which reduce the role of the search intermediaries by making it possible to generate Boolean search formulations completely automatically from natural language statements provided by the system patrons. Frequency considerations are used automatically to generate appropriate term combinations as well as Boolean connectives relating the terms. Methods are covered to produce automatic query formulations both in a standard Boolean logic system, as well as in an extended Boolean system in which the strict interpretation of the connectives is relaxed. Experimental results are supplied to evaluate the effectiveness of the automatic query formulation process, and methods are described for applying the automatic query formulation process in practice.

Cybernetic systems based on inductive logic

NASA Astrophysics Data System (ADS)

Fry, Robert L.

2001-05-01

Recent work in the area of inductive logic suggests that cybernetics might be quantified and reduced to engineering practice. If so, then there are considerable implications for engineering, science, and other fields. This paper attempts to capture the essential ideas of cybernetics cast in the light of inductive logic. The described inductive logic extends conventional logic by adding a conjugate logical domain of questions to the logical domain of assertions intrinsic to Boolean Algebra with which most are familiar. This was first posited and developed by Richard Cox. Interestingly enough, these two logical domains, one of questions and the other of assertions, only exist relative to one another with each possessing natural measures of entropy and probability, respectively. Examples are given that highlight the utility of cybernetic approaches to neuroscience, algorithm design, system engineering, and the design and understanding of defensive and offensive systems. For example, the application of cybernetic approaches to defense systems suggests that these systems possess a wavefunction which like quantum mechanics, collapses when we ``look'' through the eyes of the system sensors such as radars and optical sensors. .

A Strategy for Minimizing Background Signal in Autoinductive Signal Amplification Reactions for Point-of-Need Assays.

PubMed

Brooks, Adam D; Yeung, Kimy; Lewis, Gregory G; Phillips, Scott T

2015-09-07

Rapid point-of-need assays are used to detect abundant biomarkers. The development of in situ signal amplification reactions could extend these assays to screening and triaging of patients for trace levels of biomarkers, even in resource-limited settings. We, and others, have developed small molecule-based in situ signal amplification reactions that eventually may be useful in this context. Herein we describe a design strategy for minimizing background signal that may occur in the absence of the target analyte, thus moving this in situ signal amplification approach one step closer to practical applications. Specifically, we describe allylic ethers as privileged connectors for linking detection and propagating functionality in a small molecule signal amplification reagent. Allylic ethers minimize background reactions while still enabling controlled release of a propagating signal in order to continue the signal amplification reaction. This paper characterizes the ability of allylic ethers to provide an amplified response, and offers insight into additional design considerations that are needed before in situ small molecule-based signal amplification becomes a viable strategy for point-of-need diagnostics.

This paper characterizes the ability of allylic ethers to provide an amplified response, and offers insight into additional design considerations that are needed before in situ small molecule-based signal amplification becomes a viable strategy for point-of-need diagnostics.

Projecting adverse event incidence rates using empirical Bayes methodology.

PubMed

Ma, Guoguang Julie; Ganju, Jitendra; Huang, Jing

2016-08-01

Although there is considerable interest in adverse events observed in clinical trials, projecting adverse event incidence rates in an extended period can be of interest when the trial duration is limited compared to clinical practice. A naïve method for making projections might involve modeling the observed rates into the future for each adverse event. However, such an approach overlooks the information that can be borrowed across all the adverse event data. We propose a method that weights each projection using a shrinkage factor; the adverse event-specific shrinkage is a probability, based on empirical Bayes methodology, estimated from all the adverse event data, reflecting evidence in support of the null or non-null hypotheses. Also proposed is a technique to estimate the proportion of true nulls, called the common area under the density curves, which is a critical step in arriving at the shrinkage factor. The performance of the method is evaluated by projecting from interim data and then comparing the projected results with observed results. The method is illustrated on two data sets. © The Author(s) 2013.

Resilient guaranteed cost control of a power system.

Soliman, Hisham M; Soliman, Mostafa H; Hassan, Mohammad F

2014-05-01

With the development of power system interconnection, the low-frequency oscillation is becoming more and more prominent which may cause system separation and loss of energy to consumers. This paper presents an innovative robust control for power systems in which the operating conditions are changing continuously due to load changes. However, practical implementation of robust control can be fragile due to controller inaccuracies (tolerance of resistors used with operational amplifiers). A new design of resilient (non-fragile) robust control is given that takes into consideration both model and controller uncertainties by an iterative solution of a set of linear matrix inequalities (LMI). Both uncertainties are cast into a norm-bounded structure. A sufficient condition is derived to achieve the desired settling time for damping power system oscillations in face of plant and controller uncertainties. Furthermore, an improved controller design, resilient guaranteed cost controller, is derived to achieve oscillations damping in a guaranteed cost manner. The effectiveness of the algorithm is shown for a single machine infinite bus system, and then, it is extended to multi-area power system.

Essentials Warfarin typically requires International Normalized Ratio (INR) testing at least every 4 weeks. We implemented extended INR testing for stable warfarin patients in six anticoagulation clinics. Use of extended INR testing increased from 41.8% to 69.3% over the 3 year study. Use of extended INR testing appeared safe and effective. Background A previous single-center randomized trial suggested that patients with stable International Normalized Ratio (INR) values could safely receive INR testing as infrequently as every 12 weeks. Objective To test the success of implementation of an extended INR testing interval for stable warfarin patients in a practice-based, multicenter collaborative of anticoagulation clinics. Methods At six anticoagulation clinics, patients were identified as being eligible for extended INR testing on the basis of prior INR value stability and minimal warfarin dose changes between 2014 and 2016. We assessed the frequency with which anticoagulation clinic providers recommended an extended INR testing interval (> 5 weeks) to eligible patients. We also explored safety outcomes for eligible patients, including next INR values, bleeding events, and emergency department visits. Results At least one eligible period for extended INR testing was identified in 890 of 3362 (26.5%) warfarin-treated patients. Overall, the use of extended INR testing in eligible patients increased from 41.8% in the first quarter of 2014 to 69.3% in the fourth quarter of 2016. The number of subsequent out-of-range next INR values were similar between eligible patients who did and did not have an extended INR testing interval (27.3% versus 28.4%, respectively). The numbers of major bleeding events were not different between the two groups, but rates of clinically relevant non-major bleeding (0.02 per 100 patient-years versus 0.09 per 100 patient-years) and emergency department visits (0.07 per 100 patient-years versus 0.19 per 100 patient-years) were lower for eligible patients with extended INR testing intervals than for those with non-extended INR testing intervals. Conclusions Extended INR testing for stable warfarin patients can be successfully and safely implemented in diverse, practice-based anticoagulation clinic settings. © 2018 International Society on Thrombosis and Haemostasis.

Attributes of innovations and approaches to scalability – lessons from a national program to extend the scope of practice of health professionals

PubMed Central

Masso, Malcolm; Thompson, Cristina

2016-01-01

The context for the paper was the evaluation of a national program in Australia to investigate extended scopes of practice for health professionals (paramedics, physiotherapists, and nurses). The design of the evaluation involved a mixed-methods approach with multiple data sources. Four multidisciplinary models of extended scope of practice were tested over an 18-month period, involving 26 organizations, 224 health professionals, and 36 implementation sites. The evaluation focused on what could be learned to inform scaling up the extended scopes of practice on a national scale. The evaluation findings were used to develop a conceptual framework for use by clinicians, managers, and policy makers to determine appropriate strategies for scaling up effective innovations. Development of the framework was informed by the literature on the diffusion of innovations, particularly an understanding that certain attributes of innovations influence adoption. The framework recognizes the role played by three groups of stakeholders: evidence producers, evidence influencers, and evidence adopters. The use of the framework is illustrated with four case studies from the evaluation. The findings demonstrate how the scaling up of innovations can be influenced by three quite distinct approaches – letting adoption take place in an uncontrolled, unplanned, way; actively helping the process of adoption; or taking deliberate steps to ensure that adoption takes place. Development of the conceptual framework resulted in two sets of questions to guide decisions about scalability, one for those considering whether to adopt the innovation (evidence adopters), and the other for those trying to decide on the optimal strategy for dissemination (evidence influencers).

PubMed

Lampkin, Stacie J; Gildon, Brooke; Benavides, Sandra; Walls, Kelly; Briars, Leslie

2018-01-01

Pediatric clinical pharmacists are an integral part of the health care team. By practicing in an ambulatory care clinic, they can reduce the risk of medication errors, improve health outcomes, and enhance patient care. Unfortunately, because of limited data, misconceptions surrounding the role of pharmacists, and reimbursement challenges, there may be difficulty in establishing or expanding pediatric clinical pharmacy services to an ambulatory care setting. The purpose of this paper is to provide an overview of considerations for establishing or expanding pharmacy services in a pediatric ambulatory care clinic. The primer will discuss general and pediatric-specific pharmacy practice information, as well as potential barriers, and recommendations for identifying a practice site, creating a business plan, and integrating these services into a clinic setting.

Therapeutic boundaries in telepsychology: Unique issues and best practice recommendations

PubMed Central

Drum, Katherine B.; Littleton, Heather L.

2014-01-01

Technology-assisted mental health services are becoming much more routinely utilized by clients and practitioners alike. Clinicians practicing telepsychology must prepare themselves in order to provide competent care in this ever-evolving context of service delivery. Although much has been written with regards to considerations of ethical and legal practice, practical and logistical guidelines, and the advantages and disadvantages of the delivery of services via the use of technology, little to no attention has been paid to issues related to therapeutic boundaries in the telepsychology relationship. Clinicians must consider how to maintain appropriate boundaries in telepsychology settings in order to prevent harm and optimize treatment gains. Such considerations are also necessary given that it is probable that the telepsychology clinician will encounter novel boundary issues that are unlikely to occur in the traditional face-to-face therapy setting. We discuss the clinical utility of boundaries, potential boundary issues in telepsychology settings, and suggested best practice recommendations to ensure competent, ethical, and efficacious treatment in this novel context of service delivery.

Internationally, childhood obesity is a major public health concern. Given the established difficulties in treating obesity, designing and evaluating effective obesity prevention interventions are research priorities. As parents play a crucial role in establishing positive health behaviours in children, they are a key target for child obesity prevention programs. However, recruiting and engaging parents in such interventions can be a considerable challenge for researchers and practitioners. Members of the ‘Parenting, Child Behaviour and Well-being’ stream of the Australasian Child and Adolescent Obesity Research Network (ACAORN) have considerable and varied expertise in conducting such interventions and can provide insights into addressing these challenges. This paper aims to highlight considerations regarding the design, implementation, and evaluation of obesity prevention interventions with families and provide practical insights and recommendations for researchers and practitioners conducting family-based research in this area. Case studies of three family-based interventions conducted by ACAORN members are highlighted to provide examples and contextualise the recommendations proposed. PMID:27834820

The National Institute for Occupational Safety and Health (NIOSH) WorkLife Initiative (WLI) [http://www.cdc.gov/niosh/worklife] seeks to promote workplace programs, policies, and practices that result in healthier, more productive employees through a focus simultaneously on disease prevention, health promotion, and accommodations to age, family, and life stage. The Initiative incorporates the Institute’s foundational commitment to workplaces free of recognized hazards into broader consideration of the factors that affect worker health and wellbeing. Workplace hazards, such as physical demands, chemical exposures, and work organization, often interact with non-work factors such as family demands and health behaviors to increase health and safety risks. New workplace interventions being tested by the first three NIOSH WLI Centers of WorkLife Excellence are exploring innovative models for employee health programs to reduce the human, social, and economic costs of compromised health and quality of life. Many parties in industry, labor, and government share the goals of improving employee health while controlling health care costs. NIOSH convened a workshop in 2008 with representatives of the three Centers of Excellence to develop a comprehensive, long-range strategy for advancing the WorkLife Initiative. The recommendations below fall into three areas: practice, research, and policy. Responding to these recommendations would permit the WorkLife Center system to establish a new infrastructure for workplace prevention programs by compiling and disseminating the innovative practices being developed and tested at the Centers, and elsewhere. The WLI would also extend the customary scope of NIOSH by engaging with multiple NIH Institutes that are already generating research-to-practice programs involving the working-age population, in areas such as chronic disease prevention and management. Research to Practice (r2p) is a concept focused on the translation of research findings, technologies, and information into evidence-based prevention practices and products that are adopted in the workplace or other “real-world” settings. NIOSH’s goal is to overcome the translational issues that now prevent state-of-the-art occupational health, health promotion, and chronic disease research findings from benefiting working age populations immediately, regardless of workplace size, work sector, or region of the country.

2017-01-01

Little is known about how the extended care referral process-its structure and participants-influences Veterans' use of home and community-based services (HCBS) over nursing home care within the Veterans Health Administration (VHA). This study thus characterizes the extended care referral process within the VHA and its impact on HCBS versus nursing home use at hospital discharge. Data derive from 35 semistructured interviews at 12 Veterans Affairs Medical Centers (VAMCs). Findings indicate that the referral process is characterized by a commitment by care teams to consider HCBS if possible, varied practice depending on the clinician that most heavily influences care team recommendations, and care team emphasis on respecting Veteran/family preferences even when they are contrary to care team recommendations. Potential modifications include adopting systematic assessment practices; improving Veteran, family, and provider education; and promoting informed selection through shared decision making.

A generalized approach to complex networks

NASA Astrophysics Data System (ADS)

Costa, L. Da F.; da Rocha, L. E. C.

2006-03-01

This work describes how the formalization of complex network concepts in terms of discrete mathematics, especially mathematical morphology, allows a series of generalizations and important results ranging from new measurements of the network topology to new network growth models. First, the concepts of node degree and clustering coefficient are extended in order to characterize not only specific nodes, but any generic subnetwork. Second, the consideration of distance transform and rings are used to further extend those concepts in order to obtain a signature, instead of a single scalar measurement, ranging from the single node to whole graph scales. The enhanced discriminative potential of such extended measurements is illustrated with respect to the identification of correspondence between nodes in two complex networks, namely a protein-protein interaction network and a perturbed version of it.

Hospital leaders are seeking ways to improve resource utilization and minimize long postoperative hospital stays. Common explanations for extended stay are baseline patient illness, postoperative complications, or physician practice differences. However, the degree extended length of stay (LOS) represents illness severity or postoperative complications remains unknown. The aim is to investigate the influence of postoperative complications and patient comorbidities on extended length of stay after lumbar spine surgery in elderly patients. In this retrospective cohort study from 2008-2014, we analyzed data from the American College of Surgeons National Surgical Quality Improvement Program for elderly patients undergoing lumbar spine surgery. Patient demographics, comorbidities, LOS, and complications were recorded. Multivariable logistic regression analysis was used to determine the odds-ratio for risk-adjusted LOS. The primary outcome was the degree extended LOS represented patient illness or postoperative complications. Of 9,482 cases, 1,909 (20.13%) had extended LOS. A minority of extended LOS patients had a history of relevant comorbidities-diabetes (21.76%), COPD (8.17%), CHF (0.94%), MI (0%), acute renal failure (0.47%), and stroke (2.23%). 93% of patients with normal LOS had no complication, 5.19% had one complication, and 1.69% had greater than one complication. Among extended LOS patients, 73.65% had no complications, 18.96% had one complication, and 7.39% had greater than one complication (p<0.000). Our study suggests much of the variation in LOS for elderly lumbar spine surgery patients is not attributable to baseline patient illness or postoperative complications and therefore, most likely represents differences in practice style or surgeon preference.

Early in their careers, many new surgeons lack the background and experience to understand essential components needed to build a surgical practice. Surgical resident education is often devoid of specific instruction on the business of medicine and practice management. In particular, hepatobiliary and pancreatic (HPB) surgeons require many key components to build a successful practice secondary to significant interdisciplinary coordination and a scope of complex surgery, which spans challenging benign and malignant disease processes. In the following, we describe the required clinical and financial components for developing a successful HPB surgery practice in the nonuniversity tertiary care center. We discuss significant financial considerations for understanding community need and hospital investment, contract establishment, billing, and coding. We summarize the structural elements and key personnel necessary for establishing an effectual HPB surgical team. This article provides useful, essential information for a new HPB surgeon looking to establish a surgical practice. It also provides insight for health-care administrators as to the value an HPB surgeon can bring to a hospital or health-care system.

Novice to expert practice via postprofessional athletic training education: a grounded theory.

PubMed

Neibert, Peter J

2009-01-01

To discover the theoretic constructs that confirm, disconfirm, or extend the principles and their applications appropriate for National Athletic Trainers' Association (NATA)-accredited postprofessional athletic training education programs. Interviews at the 2003 NATA Annual Meeting & Clinical Symposia. Qualitative study using grounded theory procedures. Thirteen interviews were conducted with postprofessional graduates. Participants were purposefully selected based on theoretic sampling and availability. The transcribed interviews were analyzed using open coding, axial coding, and selective coding procedures. Member checks, reflective journaling, and triangulation were used to ensure trustworthiness. The participants' comments confirmed and extended the current principles of postprofessional athletic training education programs and offered additional suggestions for more effective practical applications. The emergence of this central category of novice to expert practice is a paramount finding. The tightly woven fabric of the 10 processes, when interlaced with one another, provides a strong tapestry supporting novice to expert practice via postprofessional athletic training education. The emergence of this theoretic position pushes postprofessional graduate athletic training education forward to the future for further investigation into the theoretic constructs of novice to expert practice.

Exploring synchronisation in nonlinear data assimilation

NASA Astrophysics Data System (ADS)

Rodrigues-Pinheiro, Flavia; van Leeuwen, Peter Jan

2016-04-01

Present-day data assimilation methods are based on linearizations and face serious problems in strongly nonlinear cases such as convection. A promising solution to this problem is a particle filter, which provides a representation of the model probability density function (pdf) by a discrete set of model states, or particles. The basic particle filter uses Bayes's theorem directly, but does not work in high-dimensional cases. The performance can be improved by considering the proposal density freedom. This allows one to change the model equations to bring the particles closer to the observations, resulting in very efficient update schemes at observation times, but extending these schemes between observation times is computationally expensive. Simple solutions like nudging have been shown to be not powerful enough. A potential solution might be synchronization, in which one tries to synchronise the model of a system with the true evolution of the system via the observations. In practice this means that an extra term is added to the model equations that hampers growth of instabilities on the synchronization manifold. Especially the delayed versions, where observations are allowed to influence the state in the past have shown some remarkable successes. Unfortunately, all efforts ignore errors in the observations, and as soon as these are introduced the performance degrades considerably. There is a close connection between time-delayed synchronization and a Kalman Smoother, which does allow for observational (and other) errors. In this presentation we will explore this connection to the full, with a view to extend synchronization to more realistic settings. Specifically performance of the spread of information from observed to unobserved variables is studied in detail. The results indicate that this extended synchronisation is a promising tool to steer the model states towards the observations efficiently. If time permits, we will show initial results of embedding the new synchronization method into a particle filter.

1951-01-01

The investigations carried out in a previous report (NACA TM 1325) concerning the flow about ring-shaped cowlings were extended by taking a circulation about the cowling into consideration. The present second report treats bodies of infinite length with approximately smooth entrance. The circulation was caused by distributing vortex rings of constant density over a stream surface extending to infinity. Furthermore, the influence of a hub body on such cowlings was dealt with. The examples treated are meant to give the designer a basis for his design.

Ion acceleration from thin foil and extended plasma targets by slow electromagnetic wave and related ion-ion beam instability

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bulanov, S. V.; A. M. Prokhorov Institute of General Physics RAS, Moscow, 119991; Esirkepov, T. Zh.

When ions are accelerated by the radiation pressure of a laser pulse, their velocity cannot exceed the pulse group velocity which can be considerably smaller than the speed of light in vacuum. This is demonstrated in two cases corresponding to a thin foil target irradiated by high intensity laser light and to the hole boring produced in an extended plasma by the laser pulse. It is found that the beams of accelerated ions are unstable against Buneman-like and Weibel-like instabilities which results in the broadening of the ion energy spectrum.

The use of supersonic molecular beams in photoionization mass spectroscopy and photoelectron spectroscopy to assist in the understanding of photoexcitation in the vacuum ultraviolet is described. Rotational relaxation and condensation due to supersonic expansion were shown to offer new possibilities for molecular photoionization studies. Molecular beam photoionization mass spectroscopy has been extended above 21 eV photon energy by the use of Stanford Synchrotron Radiation Laboratory (SSRL) facilities. Design considerations are discussed that have advanced the state-of-the-art in high resolution vuv photoelectron spectroscopy. To extend gas-phase studies to 160 eV photon energy, a windowless vuv-xuv beam line design is proposed.

Online Attention Training for Older Adults.

Wennberg, Alexandra; Kueider, Alexandra; Spira, Adam; Adams, Gregory; Rager, Robert; Rebok, George

Evidence suggests that cognitive training interventions can improve older adults' cognitive performance. Successful training programs are adaptable and train multiple cognitive domains to target individual strengths and weaknesses. Computerized training programs are useful because they allow older adults to easily access training. This pilot study used an online attention training program, ATTENTION WORKOUT™, to enhance three aspects of attention- coordination , allocation , and selective focus -in community-dwelling older adults randomized to either an abbreviated (n=13) or an extended (n=17) practice training program over a 6-week period. Participants in the extended practice group significantly improved on selective focus reading distraction tasks with unrelated words (U=39.5; Z=-2.34; p =.02) and blanks (U=26.5; Z=-3.05; p =.002) as well as a matching attributes task (U=49.5; Z=-2.33; p =.02). The extended practice group significantly improved on three tasks of coordinating attention - radio-tuning (U=30; Z=-2.73; p =.01), circuit-breaker resetting (U=46; Z=-2.24; p =.03), and the combination of the two tasks (U=15; Z=-3.51; p <.0001) - as well as a memory generalization task (U=20; Z=-3.27; p =.001). A post-test satisfaction survey found both groups enjoyed the program, but the abbreviated practice group felt the tasks were more difficult. These findings suggest online attention training programs, like ATTENTION WORKOUT, can improve attention-related skills in community-dwelling older adults.

Survey of Information Sharing Related to the Occupational Considerations of Working Cancer Patients Between Occupational Physicians and Treating Physicians.

Although a vital element in providing career support to workers with medical ailments is coordination between the worker, the treating physician, and the company (the occupational health staff), little is known about factors that promote or impede coordination between these parties. This study aims to demonstrate what kinds of actions by treating physicians promote or impede the occupational considerations made by occupational physicians. A total of 43 occupational physicians who had completed the postgraduate training course (4 years) at the University of Occupational and Environmental Health Japan and were current or former instructors at the Occupational Health Training Center were surveyed using a self-reported questionnaire form. The questionnaire asked about individual attributes (age, years of experience as an occupational physician, etc.) and actions taken by treating physicians that were useful in making occupational considerations in the workplace (good practice cases) or that impeded such considerations (trouble cases). Responses about cases were obtained as freely written descriptions. Case content was analyzed qualitatively according to the KJ method. During the survey period from December 17, 2013 to January 18, 2014, responses were received from 33 occupational physicians (valid response rate, 76.7%; mean age, 37.4±6.1 years). Of these, 60.6% exclusively specialized in occupational medicine. Respondents provided 32 good practice cases and 16 trouble cases. The timing of coordination was the period of rehabilitation in 35 of the 48 cases (72.9%). Actions by the treating physicians that influenced occupational considerations were divided into seven major categories: "providing treatment information," "providing physical information," "appropriateness of rehabilitation or occupational considerations," "consistency of information provided," "issuing documentation," "communication that was cognizant of the occupational physician's presence," and "providing information unknown to the worker." This study clarified the kind of actions by the treating physicians that were relevant to occupational support provided by occupational physicians. Additionally, this study clarified the need for information sharing with occupational physician and treating physician. The good practice cases and trouble cases presented by the respondents were inextricably linked, and actions by the treating physicians that are based on good practices are highly likely to lead to smooth information sharing and occupational considerations.

Children, health and gender: recognition in nursing research?

PubMed

Taylor, Julie; Green, Lorraine

2008-12-01

This paper examines the hitherto mostly unrecognised relationship between gender, health and children; its significance for nursing practice and how it has been considered in nursing research. Holistic nursing practice with children requires adequate assessment and consideration of all potential influences on children's lives. Socioeconomic disparities have received widespread attention and gender inequalities in adult health have been studied in some depth. The links between gender, health and children, however, have received little consideration. The paper first considers this context in depth; it then applies the context to research in practice. Systematic review. A systematic literature search was undertaken on four mainstream nursing research journals over 38 months up to February 2007. A total of 567 articles met the key word searches. Duplicates, opinion pieces and articles not focusing on children were removed. The remaining 23 nursing studies relevant to child health were examined for their gender sensitivity. Full consideration of gender issues was found largely to be absent in nursing research on children. Eight studies gave specific consideration to gender relevance, where boys and girls may have responded differently to care. Only six studies specifically addressed gender sensitivity. Allowing children a voice, however, was a strength in these studies, with 18 reflecting children's views directly. Major gaps still exist in research and theorisation relating to children, health and gender. These need to be acknowledged and investigated, particularly in relation to how they might impact on nursing care. Nursing practice and research needs to account for all potential health issues, of which gender may often be important.

Enabling narrative pedagogy: inviting, waiting, and letting be.

PubMed

Ironside, Pamela M

2014-01-01

This article describes how teachers enable Narrative Pedagogy in their courses by explicating the Concernful Practice Inviting: Waiting and Letting Be. Narrative Pedagogy, a research-based, phenomenological approach to teaching and learning, extends conventional pedagogies and offers nursing faculty an alternative way of transforming their schools and courses. Using hermeneutic phenomenology, interview data collected over a 10-year period were analyzed by coding practical examples of teachers' efforts to enact Narrative Pedagogy. When Narrative Pedagogy is enacted, teachers and students focus on thinking and learning together about nursing phenomena and seek new understandings about how they may provide care in the myriad situations they encounter. Although the Concernful Practices co-occur, explicating inviting experiences can assist new teachers, and those seeking to extend their pedagogical literacy, by providing new understandings of how Narrative Pedagogy can be enacted.

Assessing the risk of recurrent venous thromboembolism – a practical approach

PubMed Central

Fahrni, Jennifer; Husmann, Marc; Gretener, Silvia B; Keo, Hong H

2015-01-01

Recurrent venous thromboembolism (VTE) is associated with increased morbidity and mortality. This risk is lowered by anticoagulation, with a large effect in the initial phase following the venous thromboembolic event, and with a smaller effect in terms of secondary prevention of recurrence when extended anticoagulation is performed. On the other hand, extended anticoagulation is associated with an increased risk of major bleeding and thus leads to morbidity and mortality. Therefore, it is necessary to assess the risk of recurrence for VTE on an individual basis, and a recommendation for secondary prophylaxis should be specifically based on risk calculation of recurrence of VTE and bleeding. In this review, we provide a comprehensive summary of relevant risk factors for recurrent VTE and a practical approach for assessing the risk of recurrence in daily practice. PMID:26316770

Exploring our outer solar system - The Giant Planet System Observers

NASA Astrophysics Data System (ADS)

Cooper, J. F.; Sittler, E. C., Jr.; Sturner, S. J.; Pitman, J. T.

As space-faring peoples now work together to plan and implement future missions that robotically prepare for landing humans to explore the Moon, and later Mars, the time is right to develop evolutionary approaches for extending this next generation of exploration beyond Earth's terrestrial planet neighbors to the realm of the giant planets. And while initial fly-by missions have been hugely successful in providing exploratory surveys of what lies beyond Mars, we need to consider now what robotic precursor mission capabilities we need to emplace that prepare us properly, and comprehensively, for long-term robotic exploration, and eventual human habitation, beyond Mars to the outer reaches of our solar system. To develop practical strategies that can establish prioritized capabilities, and then develop a means for achieving those capabilities within realistic budget and technology considerations, and in reasonable timeframes, is our challenge. We suggest one component of such an approach to future outer planets exploration is a series of Giant Planets System Observer (GPSO) missions that provide for long- duration observations, monitoring, and relay functions to help advance our understanding of the outer planets and thereby enable a sound basis for planning their eventual exploration by humans. We envision these missions as being comparable to taking Hubble-class remote-sensing facilities, along with the space physics capabilities of long-lived geospace and heliospheric missions, to the giant planet systems and dedicating long observing lifetimes (HST, 16 yr.; Voyagers, 29 yr.) to the exhaustive study and characterization of those systems. GPSO missions could feature 20-yr+ extended mission lifetimes, direct inject trajectories to maximize useful lifetime on target, placement strategies that take advantage of natural environment shielding (e.g., Ganymede magnetic field) where possible, orbit designs having favorable planetary system viewing geometries, comprehensive broadband remote sensing capabilities, a complementary and redundant science instrument suite, fully autonomous operations, high bandwidth science data downlink, advanced solar power technologies (supplemented where necessary), functional interfaces that are compatible with future small fly-by missions, and fail-safe features for mission operations and planetary protection, 1 among other considerations. We describe in this paper one example of a GPSO-type mission our team has been formulating as a practical approach that addresses many of the most highly-rated future science exploration needs in the Jovian system, including the exploration of Europa, observation of Io and Ganymede, and characterization of the Jovian atmosphere. We call this mission concept the Ganymede Exploration Observer with Probes (GEOP), and describe its architecture, mission design, system features, science capabilities, key trades, and notional development plan for implementation within the next decade. 2

Saving the spandrels? Adaptive genomic variation in conservation and fisheries management.

PubMed

Pearse, D E

2016-12-01

As highlighted by many of the papers in this issue, research on the genomic basis of adaptive phenotypic variation in natural populations has made spectacular progress in the past few years, largely due to the advances in sequencing technology and analysis. Without question, the resulting genomic data will improve the understanding of regions of the genome under selection and extend knowledge of the genetic basis of adaptive evolution. What is far less clear, but has been the focus of active discussion, is how such information can or should transfer into conservation practice to complement more typical conservation applications of genetic data. Before such applications can be realized, the evolutionary importance of specific targets of selection relative to the genome-wide diversity of the species as a whole must be evaluated. The key issues for the incorporation of adaptive genomic variation in conservation and management are discussed here, using published examples of adaptive genomic variation associated with specific phenotypes in salmonids and other taxa to highlight practical considerations for incorporating such information into conservation programmes. Scenarios are described in which adaptive genomic data could be used in conservation or restoration, constraints on its utility and the importance of validating inferences drawn from new genomic data before applying them in conservation practice. Finally, it is argued that an excessive focus on preserving the adaptive variation that can be measured, while ignoring the vast unknown majority that cannot, is a modern twist on the adaptationist programme that Gould and Lewontin critiqued almost 40 years ago.

Team deliberate practice in medicine and related domains: a consideration of the issues.

PubMed

Harris, Kevin R; Eccles, David W; Shatzer, John H

2017-03-01

A better understanding of the factors influencing medical team performance and accounting for expert medical team performance should benefit medical practice. Therefore, the aim here is to highlight key issues with using deliberate practice to improve medical team performance, especially given the success of deliberate practice for developing individual expert performance in medicine and other domains. Highlighting these issues will inform the development of training for medical teams. The authors first describe team coordination and its critical role in medical teams. Presented next are the cognitive mechanisms that allow expert performers to accurately interpret the current situation via the creation of an accurate mental "model" of the current situation, known as a situation model. Following this, the authors propose that effective team performance depends at least in part on team members having similar models of the situation, known as a shared situation model. The authors then propose guiding principles for implementing team deliberate practice in medicine and describe how team deliberate practice can be used in an attempt to reduce barriers inherent in medical teams to the development of shared situation models. The paper concludes with considerations of limitations, and future research directions, concerning the implementation of team deliberate practice within medicine.

Specialty Practice and Cost Considerations in the Management of Uveitis Associated With Juvenile Idiopathic Arthritis.

2016-07-01

To evaluate whether cost, prior insurance authorization concerns, and subspecialty practice influence therapeutic decisions in the treatment of uveitis associated with juvenile idiopathic arthritis. A total of 2,965 pediatric ophthalmologists, uveitis specialists, retina specialists, and rheumatologists across the United States were surveyed via e-mail regarding their choice in long-term therapy for a hypothetical patient with uveitis associated with juvenile idiopathic arthritis. Outcomes of interest were differences in therapy choice based on cost/prior authorization and specialty practice. There were significant differences in the use of methotrexate and biologics among specialists, both with and without consideration for cost and prior authorization. Physicians in four different specialties who treat uveitis associated with juvenile idiopathic arthritis agree on methotrexate as a first-line treatment choice and a biologic immunosuppressive medication as a second choice, but there are significant differences between the specialties in their use of these medications. Cost and insurance considerations did not affect therapy selection. [J Pediatr Ophthalmol Strabismus. 2016;53(4):246-251.]. Copyright 2016, SLACK Incorporated.

Yao, Yu; Wu, Lenan; Zhao, Junhui

2017-12-01

Extended binary phase shift keying/M-ary position phase shift keying (EBPSK/MPPSK)-MODEM provides radar and communication functions on a single hardware platform with a single waveform. However, its range estimation accuracy is worse than continuous-wave (CW) radar because of the imbalance of power in two carrier frequencies. In this article, the power allocation method for dual-frequency EBPSK/MPPSK modulated systems is presented. The power of two signal transmitters is adequately allocated to ensure that the power in two carrier frequencies is equal. The power allocation ratios for two types of modulation systems are obtained. Moreover, considerations regarding the range of operation of the dual-frequency system are analysed. In addition to theoretical considerations, computer simulations are provided to illustrate the performance.

Direct design of aspherical lenses for extended non-Lambertian sources in two-dimensional geometry

PubMed Central

Wu, Rengmao; Hua, Hong; Benítez, Pablo; Miñano, Juan C.

2016-01-01

Illumination design for extended sources is very important for practical applications. The existing direct methods that are all developed for extended Lambertian sources are not applicable to extended non-Lambertian sources whose luminance is a function of position and direction. What we present in this Letter is to our knowledge the first direct method for extended non-Lambertian sources. In this method, the edge rays and the interior rays are both used, and the output intensity at a given direction is calculated to be the integral of the luminance function of all the outgoing rays at this direction. No cumbersome iterative illuminance compensation is needed. Two examples are presented to demonstrate the elegance of this method in prescribed intensity design for extended non-Lambertian sources in two-dimensional geometry. PMID:26125361

Cost efficiency and reimbursement of remote monitoring: a US perspective.

PubMed

Slotwiner, David; Wilkoff, Bruce

2013-06-01

Demographic and technological changes are driving increased utilization of cardiac implantable electronic devices (CIEDs) remote monitoring. In the USA, fee-for-service model of healthcare delivery, services rendered are valued based upon time, intensity, and technical or practice expense costs. As a consequence of this perspective, and to contain spending, Medicare has grouped physician services into families. Spending within each family of services must, by law, remain budget neutral. Cardiac implantable electronic devices monitoring services, remote and in-person, are grouped into one family. As the volume of services within this family increases, the individual encounters are destined to be discounted into ever decreasing portions. However, if the value of remote monitoring is demonstrated to extend beyond the previous boundaries of in-person interrogations, a rational request can be made to reconsider the relative value of remote monitoring. Outcome data supporting the value-added benefits of remote monitoring are rapidly accumulating, including (i) patient convenience, with reduced use of office services, (ii) equal safety compared with in-person evaluation, (iii) shorter detection time to actionable events (arrhythmias, cardiovascular disease progression, and device malfunction), (iv) reduced length of stay for hospitalizations, (v) reduced inappropriate shocks, (vi) increased battery longevity, and (vii) a relative reduction in the risk of death. Fully automatic wireless technology, only recently widely implemented, will add considerable clinical efficiencies and further increase the value of remote monitoring. The U.S. challenge will be to appropriately define the relative value of CIEDs remote monitoring now that outcome data have demonstrated its value extends beyond in-person interrogation.

Healy, M L

2000-06-01

1. Information technology has moved "work" out of a centralized location. Employees who telecommute pose significant challenges and considerations for the practice of occupational health nursing. 2. Employer and employee benefits associated with telecommuting are reportedly associated with high levels of job satisfaction. However, the occupational health and safety risks of this new work environment need to be fully assessed and understood. 3. The ergonomic controls to minimize the risk of repetitive motion injuries are the same for both office and home locations. Additional attention need to be paid to implementing risk controls for other physical hazards and psychosocial considerations, as well as personal safety and security issues. 4. The scope of occupational health nursing practice needs to remain dynamic, recognizing the impact new technologies have on the workplace, to continue to meet the needs of the changing workplace.

The first edition of the Journal of Space Economics will focus on issues likely to arise during the course of the International Lunar Decade 2020-2030.

Practical considerations for disaster preparedness and continuity management in research facilities.

PubMed

Mortell, Norman; Nicholls, Sam

2013-10-01

Many research facility managers, veterinarians and directors are familiar with the principles of Good Laboratory Practice, requirements of the Association for Assessment and Accreditation of Laboratory Animal Care International, tenets of biosecurity and standards of animal welfare and housing but may be less familiar with the ideas of business continuity. But business continuity considerations are as applicable to research facilities as they are to other institutions. The authors discuss how business continuity principles can be applied in the research context and propose that such application, or 'research continuity management,' enables a focused but wide-reaching approach to disaster preparedness.

Marketing the gastrointestinal practice: strategic considerations.

Berkowitz, Eric N

2006-10-01

The health care marketplace is changing rapidly with increasing competition, changing reimbursement, and greater shifting of cost to patients making them more price sensitive. To be financially viable, the successful gastrointestinal practice must be more market responsive in its approach to planning, develop a unique advantage that will be of value to referral sources, and understand how customers evaluate alternative competing practices. This article focuses on these elements of practice success.

Using audiology assistants allows a practice to meet the expected increase in patient demand in a cost-effective manner, without compromise to quality of patient care. Assistants are particularly valuable in private practice settings that have an emphasis in amplification, as many of the tasks involved do not require the unique skills of the doctor of audiology. Regulatory considerations, methods of training, and scope of practice of the assistant are discussed. PMID:28028327

Haller, Maria C; Vanholder, Raymond; Oberbauer, Rainer; Zoccali, Carmine; Van Biesen, Wim

2014-11-01

Medical management of patients with kidney disease is complex and resource intensive. In times of limited health care budgets, economic evaluations have become more important over the past few years in identifying interventions with a beneficial cost-effectiveness to maximize the benefits served from the available resources. However, integrating evidence from health-economic evaluations into clinical practice guidelines remains a challenge. European Renal Best Practice (ERBP), the official guideline body of the European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) herewith presents some lines of thought that need consideration in the discussion on incorporating health-economic considerations into clinical guideline development. © The Author 2013.

Defining information need in health - assimilating complex theories derived from information science.

PubMed

Ormandy, Paula

2011-03-01

Key policy drivers worldwide include optimizing patients' roles in managing their care; focusing services around patients' needs and preferences; and providing information to support patients' contributions and choices. The term information need penetrates many policy documents. Information need is espoused as the foundation from which to develop patient-centred or patient-led services. Yet there is no clear definition as to what the term means or how patients' information needs inform and shape information provision and patient care. The assimilation of complex theories originating from information science has much to offer considerations of patient information need within the context of health care. Health-related research often focuses on the content of information patients prefer, not why they need information. This paper extends and applies knowledge of information behaviour to considerations of information need in health, exposing a working definition for patient information need that reiterates the importance of considering the patient's goals and understanding the patient's context/situation. A patient information need is defined as 'recognition that their knowledge is inadequate to satisfy a goal, within the context/situation that they find themselves at a specific point in the time'. This typifies the key concepts of national/international health policy, the centrality and importance of the patient. The proposed definition of patient information need provides a conceptual framework to guide health-care practitioners on what to consider and why when meeting the information needs of patients in practice. This creates a solid foundation from which to inform future research. © 2010 The Author. Health Expectations © 2010 Blackwell Publishing Ltd.

FDA perspective on specifications for biotechnology products--from IND to PLA.

PubMed

Murano, G

1997-01-01

Quality standards are obligatory throughout development, approval and post-marketing phases of biotechnology-derived products, thus assuring product identity, purity, and potency/strength. The process of developing and setting specifications should be based on sound science and should represent a logical progression of actions based on the use of experiential data spanning manufacturing process validation, consistency in production, and characterization of relevant product properties/attributes, by multiple analytical means. This interactive process occurs in phases, varying in rigour. It is best described as encompassing a framework which starts with the implementation of realistic/practical operational quality limits, progressing to the establishment/adoption of more stringent specifications. The historical database is generated from preclinical, toxicology and early clinical lots. This supports the clinical development programme which, as it progresses, allows for further assay method validation/refinement, adoption/addition due to relevant or newly recognized product attributes or rejection due to irrelevance. In the next phase, (licensing/approval) specifications are set through extended experience and validation of both the preparative and analytical processes, to include availability of suitable reference standards and extensive product characterization throughout its proposed dating period. Subsequent to product approval, the incremental database of test results serves as a natural continuum for further evolving/refining specifications. While there is considerable latitude in the kinds of testing modalities finally adopted to establish product quality on a routine basis, for both drugs and drug products, it is important that the selection takes into consideration relevant (significant) product characteristics that appropriately reflect on identity, purity and potency.

The phenomenology of the psychotic break and Huxley's trip: substance use and the onset of psychosis.

PubMed

Nelson, Barnaby; Sass, Louis A

2008-01-01

While considerable research attention has been devoted to the causal relationship between substance use and psychosis, the phenomenology of the association between the two has largely been ignored. This is a significant shortcoming, because it blinds researchers to the possibility that there may be elements of the subjective experience of substance use and psychosis that contribute to their apparent relationship in empirical studies. The current paper examines the phenomenology of the onset of psychosis and the phenomenology of substance intoxication through consideration of two texts: Sass's account of the phenomenology of psychosis onset and Huxley's account of the experience of hallucinogenic intoxication. Sass's account of psychosis onset includes four components: Unreality, Fragmentation, Mere Being, and Apophany. The analysis reveals significant parallels - and also some differences - between this account and the phenomenology of substance intoxication. We discuss the implications of this for the causal relationship between psychosis and substance use and suggest several ways of understanding the overlapping phenomenologies. This includes the suggestion of a shared factor, perhaps best described as psychotic-like experience, which seems to involve a breakdown of the sign-referent relationship and relationship with the common-sense, practical world. However, in the onset of psychosis, this breakdown is primarily experienced as a sense of alienation from self and world, whereas in the hallucinogenic state a sense of mystical union and revelation seems predominant. Further research may extend this analysis by looking at experiences with other drugs, particularly cannabis, and by examining the phenomenology of psychotic disorder beyond the first episode.
