Full Text Available The Accreditation Council for Pharmacy Education (ACPE provides standards for colleges of pharmacy to assist in the provision of pharmacy education to student pharmacists. An integral part of all college educational programs includes the provision of experiential learning. Experiential learning allows students to gain real-world experience in direct patient care during completion of the curriculum. All college of pharmacy programs provide several Advanced Pharmacy Practice Experiences (APPEs, which include a balance between the four required experiences and a number of other required or elective APPEs. Required APPEs include advanced community, advanced institutional, ambulatory care, and general medicine. The elective APPEs include a myriad of opportunities to help provide a balanced education in experiential learning for student pharmacists. These unique opportunities help to expose student pharmacists to different career tracks that they may not have been able to experience otherwise. Not all colleges offer enough elective APPEs to enable the student pharmacist to obtain experiences in a defined area. Such an approach is required to produce skilled pharmacy graduates that are capable to enter practice in various settings. Elective APPEs are scheduled logically and are based upon student career interest and site availability. This article describes the offering, scheduling and maintenance of different elective APPEs offered by The University of Tennessee College of Pharmacy.

Undoubtedly, our society is facing new economic, political, demographic, social and cultural challenges that require healthcare services able to meet the growing health needs of the population, especially in dealing with chronic conditions. In this new context, some countries such as the United Kingdom have made a firm commitment to develop new models for chronic patients care based on the introduction of new figures of Advanced Practice Nurses, which includes 4 cornerstones of professional practice: advanced clinical skills, clinical management, teaching and research. The implementation of this new figures implies a redefinition of professional competencies and has its own accreditation system and a specific catalogue of services adapted to the population requirements, in order to provide chronic care support from Primary Care settings. This trajectory allows us analysing the process of design and implementation of these new models and the organizational structure where it is integrated. In Spain, there are already experiences in some regions such as Andalucia and the Basque Country, focused on the creation of new advanced nursing roles. At present, it is necessary to consider suitable strategic proposals for the complete development of these models and to achieve the best results in terms of overall health and quality of life of patients with chronic conditions, improving the quality of services and cost-effectiveness through a greater cohesion and performance of healthcare teams towards the sustainability of healthcare services and patient satisfaction.

Objective. To investigate whether instruction and feedback on reflective responses are beneficial in developing pharmacy students to become more reflective practitioners. Methods. Students on an advanced pharmacy practice experience answered weekly reflection questions and were randomly assigned to either an intervention (received instruction and feedback on reflection) or control group. The final week's responses were de-identified and two blinded faculty members independently categorized them as reflective or nonreflective. The primary outcome measure was comparing the number of "reflective" responses in each group. Results. The responses were classified as reflective in 83.3% of students in the intervention group (n=18) compared to 37.5% of the control group (n=16). The odds that the response was categorized as reflective were 8.3 times higher in the intervention group. Conclusion. Providing instruction and feedback to students improved the likelihood that their work was reflective. PMID:27402984

International outreach by schools and colleges of pharmacy is increasing. In this paper, we provide current practice guidelines to establish and maintain successful global/international advanced pharmacy practice experiences (G/I APPEs) with specific recommendations for home/host country and host site/institution. The paper is based on a literature review (2000-2014) in databases and Internet searches with specific keywords or terms. Educational documents such as syllabi and memoranda of understanding (MoUs) from pharmacy programs were also examined. In addition, a preliminary draft was developed and the findings and recommendations were reviewed in a 90-minute roundtable discussion at the 2014 American Association of Colleges of Pharmacy Annual Meeting. Recommendations for the host country include travel considerations (eg, passport, visa, air travel), safety, housing, transportation, travel alerts and warnings, health issues, and financial considerations. For the home country, considerations for establishment of G/I APPE site (eg, vetting process, MoU, site expectations) are described. The paper is a resource for development of new G/I APPEs and provides guidance for continuous quality improvement of partnerships focusing on G/I pharmacy education. PMID:27170809

Objective To implement and evaluate the impact of an elective evidence-based medicine (EBM) course on student performance during advanced pharmacy practice experiences (APPEs). Design A 2-hour elective course was implemented using active-learning techniques including case studies and problem-based learning, journal club simulations, and student-driven wiki pages. The small class size (15 students) encouraged independent student learning, allowing students to serve as the instructors and guest faculty members from a variety of disciplines to facilitate discussions. Assessment Pre- and posttests found that students improved on 83% of the core evidence-based medicine concepts evaluated. Fifty-four APPE preceptors were surveyed to compare the performance of students who had completed the EBM course prior to starting their APPEs with students who had not. Of the 38 (70%) who responded, the majority (86.9%) agreed that students who had completed the course had stronger skills in applying evidence-based medicine to patient care than other students. The 14 students who completed the elective also were surveyed after completing their APPEs and the 11 who responded agreed the class had improved their skills and provided confidence in using the medical literature. Conclusions The skill set acquired from this EBM course improved students' performance in APPEs. Evidence-based medicine and literature search skills should receive more emphasis in the pharmacy curriculum. PMID:21451761

Although spasticity of varying severity affects up to 80% of patients with multiple sclerosis (MS) during the course of their disease, the symptom is often overlooked and undertreated. Despite the availability of oral antispasticity treatments (baclofen, tizanidine and others), approximately one-third of MS patients in Europe and the USA experience moderate or severe nonfocalized spasticity. At present, a thorough clinical evaluation of MS-related spasticity that takes into account the patient's own perception of spasms, spasticity-related pain and other associated symptoms is not common in daily neurological practice. Some of the usual spasticity scales, such as the Ashworth and modified Ashworth scales, reflect the observer's measurement of spasticity at a particular point in time. Herbal (smoked) cannabis has long been recognized as a possible option for relief of spasticity and neuropathic pain, but pertinent concerns about psychoactive effects and addiction risk have prevented its common use. An innovative method of benefiting from the mode of action of cannabinoids while limiting their drawbacks is to reduce peak plasma levels of 9-delta-tetrahydrocannabinol and counteract psychoactivity with higher than naturally occurring proportions of a second cannabinoid, cannabidiol. Sativex® oromucosal spray (1:1 ratio of 9-delta-tetrahydrocannabinol/cannabidiol) has recently been approved in a number of EU countries and elsewhere for use in patients with MS-related spasticity who are resistant to treatment with other antispasticity medications. In clinical trials, Sativex provided initial relief of spasticity symptoms within the first 4 weeks of treatment (trial period) in up to about half of patients resistant to other available oral antispasticity medications and demonstrated clinically significant improvement in spasticity (30% or higher reduction from baseline) in three-quarters of the initial responders. Adverse events were limited mainly to mild or moderate

The purpose of this qualitative study was to examine the impact of standardized patient experiences (SPE) in the education of the Advanced Practice Nurse (APN). The education of the APN requires educators to make every attempt to promote competency in the areas of communication and clinical-decision making. SPE programs have been found to improve the interpersonal, problem solving, and critical thinking skills of nursing students. For this research twenty-nine APN students participated in SPEs over the course of two semesters. Fifteen student volunteers of those 29 participants were then interviewed three months after the experience. Results revealed that having an expert in the field of communication studies increased awareness of communication skills and how to improve nurse-patient encounters in the clinical setting. The interprofessional collaboration during the SPEs assisted in facilitating the application of learned communication skills into patient-centered care of the APN student. PMID:26122938

Advanced practice nurses (APNs) at The Hospital for Sick Children (SickKids) are pediatric healthcare providers who integrate principles and theories of advanced nursing with specialty knowledge to provide autonomous, independent, accountable, ethical and developmentally appropriate care in complex, often ambiguous and rapidly changing healthcare environments. Caring for children and adolescents requires culturally sensitive and family-centred approaches to care that incorporate a unique body of knowledge. Family-centred care is an approach to planning, delivery and evaluation of healthcare that is governed by the establishment of mutually beneficial partnerships among APNs, health professionals and children/families. The cornerstone of APN practice at SickKids is the recognition of "family" as the recipients of care. By valuing and developing relationships with families, APNs promote excellence in healthcare across the care continuum to optimize the child's and family's physical, emotional, social, psychological and spiritual well-being. This paper outlines the evolution of advanced practice nursing at SickKids, beginning with the introduction of APN roles in the 1970s and culminating in the current critical mass of APNs who have been integrated throughout the hospital's infrastructure. We describe the process used to create a common vision and a framework to guide pediatric advanced nursing practice. PMID:20530994

The Advanced Liquid Feed Experiment (ALFE) is a Hitchhiker experiment flown on board the Shuttle of STS-39 as part of the Space Test Payload-1 (STP-1). The purpose of ALFE is to evaluate new propellant management components and operations under the low gravity flight environment of the Space Shuttle for eventual use in an advanced spacecraft feed system. These components and operations include an electronic pressure regulator, an ultrasonic flowmeter, an ultrasonic point sensor gage, and on-orbit refill of an auxiliary propellant tank. The tests are performed with two transparent tanks with dyed Freon 113, observed by a camera and controlled by ground commands and an on-board computer. Results show that the electronic pressure regulator provides smooth pressure ramp-up, sustained pressure control, and the flexibility to change pressure settings in flight. The ultrasonic flowmeter accurately measures flow and detects gas ingestion. The ultrasonic point sensors function well in space, but not as a gage during sustained low-gravity conditions, as they, like other point gages, are subject to the uncertainties of propellant geometry in a given tank. Propellant transfer operations can be performed with liquid-free ullage equalization at a 20 percent fill level, gas-free liquid transfer from 20-65 percent fill level, minimal slosh, and can be automated.

With an increasing number of new pharmacy schools/colleges and expansion of existing ones, pharmacy schools/colleges are often in need of elective rotation experiences as part of the final year advanced pharmacy practice experience (APPE) program. Offering a medical missions elective APPE in either a domestic or international setting is a unique opportunity to expose pharmacy students to direct patient care. APPE students can be involved in triaging patients, compounding and dispensing medications, and providing patient education. As part of this APPE, pharmacy students are expected to complete projects such as formulary development, case presentations, book club discussions, journal reflections, manuscript preparations, and trip logistics planning. An elective APPE focused on medical missions facilitates the learning process and promotes the emergence of team leaders and leadership skills in general. PMID:22739719

Identifying, developing, and incorporating nursing's unique ontological and epistemological perspective into advanced practice nursing practice places priority on delivering care based on research-derived knowledge. Without a clear distinction of our metatheoretical space, we risk blindly adopting the practice values of other disciplines, which may not necessarily reflect those of nursing. A lack of focus may lead current advanced practice nursing curricula and emerging doctorate of nursing practice programs to mirror the logical positivist paradigm and perspective of medicine. This article presents an ontological perspective for advanced practice nursing education, practice, and research. PMID:16350595
This article describes the experiences of a dentist using a contracted dental services organization to manage the business aspects of a multisite group oral and maxillofacial practice. The need for help with management functions first became apparent in medicine, and several models emerged there. The model used in this practice sought to take advantage of specialized expertise without reducing practitioners' control over dental decisions, including those going beyond narrow clinical decisions. Personal experiences and suggestions for best fit between practices on contracted services are presented. PMID:26562977
Purpose: The purpose of this discussion paper is to explore issues related to advanced practice for therapy radiographers. Key themes: The paper will focus on key themes that have impacted on advanced practice for therapy radiographers such as government initiatives and policy, confounding terminology associated with advanced practice such as role extension, role expansion, role development, and expert practice. The theory and development of expert practice is explored and paralleled to existing roles in therapy using the Benner model to define stages of professional development and competence. Evidence for advanced practice, and education and training will also be explored. All of these issues will be considered within the perspective of the current clinical and political environment that therapy radiographers operate in. Conclusions: The application of advanced practice can and should incorporate elements of role extension and role development, with some tangible skills ladder to guide and shape the development of potential consultant practitioners. There is a need to identify the current position of advanced practice nationally, and to monitor existing and emerging roles, possibly though a longitudinal study. The skill mix as a whole within departments need to be part of an ongoing evaluation with close collaboration between the professional body, departmental managers and higher education institutes to develop curricula to support existing and emerging roles. There are also key lessons to be learned from other professions with more experience with advanced practitioners if recruitment and retention is not going to continue to be a problem
Imprecise probability theories are considered useful in reliability and risk assessments, but some of them were found to be unsatisfactory. This paper summarizes the authors' experience in dealing with the Dempster-Shafer theory of evidence and demonstrates the authors' advances in the application of the theory of coherent imprecise probabilities for reliability assessments. The obtained lower and upper reliabilities of series, parallel and general systems have very specific useful properties that cannot be obtained in the framework of standard probability theory

For more than 25 years, advanced practice nurses have been incrementally included as a part of the health care financing structure. Following physician payment revisions at the federal level, advanced practice nurses were overtly recognized as Medicare providers and have participated in the establishment of current procedural terminology codes and the subsequent relative work values associated with payment. Success in this regard has been the result of business, political, and policy savvy that has important lessons for moving forward in any health care restructuring for both nurses and advanced practice nurses. Principles of valuing nurse work, time, and intensity in the Resource-Based Relative Value Scale are discussed with implications for future opportunities of measuring nursing work and any potential relationship to quality outcomes of care.

Allied health and nursing professionals are continuing to expand their responsibilities into clinical areas outside their traditional spheres of interest; typically, many of these new responsibilities are found within the medical (doctor) domain. Such responsibilities are often at an advanced clinical level and consequently higher demands are placed upon the professionals, not least in terms of clinical updating, competence to practice and also legal liability. This article explores the legal implications of practising at an advanced clinical level with particular reference to legal claims. The first part of the article commences with an outline of pertinent law in England and Wales. The latter part of the article explores actual cases from which allied health professionals (eg radiographers) can gain valuable information. Throughout the article suggestions for good practice are indicated. Examples of good practice include: the need to base your practice on evidence and peer practice; the need to keep detailed records (protocols) of such practice; the need to know when you are at the limit of your ability; and as such when to ask for advice from a medical practitioner/radiologist
Developing and assessing alternatives is a key and central stage to Strategic Environmental Assessment (SEA). However, research has repeatedly reported this stage as one of the most poorly undertaken aspects of the SEA process. Current practice limitations include belated consideration of reasonable alternatives, narrow scope of alternatives that often include unrealistic or retrofitted options, limited stakeholder and public involvement in their identification, assessment and selection, lack of systematic approaches to their assessment and comparison, and inadequate reporting of the ‘storyline’ on how they were identified, what the potential impacts are and why the preferred alternative was selected. These issues have resulted in objections and judicial reviews. On the positive side, a number of good practice case studies enable extraction of key lessons and formulation of a set of general recommendations to advance practice in SEA alternatives. In this paper, practical guidance on the identification and development of alternatives, their assessment and comparison, selection of the preferred option, and documentation of the process and the reasons for selection is provided and discussed to frame good practice approaches. - Highlights: • Alternatives are one of the most poorly completed aspects of Strategic Environmental Assessment. • Current practice limitations need to be addressed to enhance SEA effectiveness. • A set of recommendations are extracted from good practice case studies. • These recommendations can be applied across jurisdictions and sectors and tailored as necessary

Advanced practice nurses positively impact the delivery of healthcare and client outcomes. However, in the past these positions have been seen to have variable value and were often vulnerable during budget cuts. Lack of a clear advanced nursing practice (ANP) framework probably contributed to the compromised effectiveness of these roles and evolution of roles with different titles, scopes of practice and reporting structures. To build the foundation for developing an ANP framework, a task force at The Ottawa Hospital (TOH) conducted a literature review related to ANP roles and completed a review of all clinical nursing roles at TOH. In addition, focus groups with nurses and other health professionals elicited ANP perceptions. The ANP framework includes a standardized job description that details competencies under five role components: clinical practice; consultation; research; education; and, leadership. Recommendations for assessment, implementation and evaluation of ANP roles are identified. The process undertaken by our ANP task force proved to be thorough and sound in developing a framework within which to move forward with ANP role implementation throughout TOH. This article, describing the process, may assist other organizations in defining ANP roles to better meet patient needs in changing health care environments. PMID:11803945

A new reduced size ITER-RC superconducting tokamak concept is proposed with the goals of studying burn physics either in an inductively driven standard tokamak (ST) mode of operation, or in a quasi-steady state advanced tokamak (AT) mode sustained by non-inductive means. This is achieved by reducing the radiation shield thickness protecting the superconducting magnet by 0.34 m relative to ITER and limiting the burn mode of operation to pulse lengths as allowed by the TF coil warming up to the current sharing temperature. High gain (Q≅10) burn physics studies in a reversed shear equilibrium, sustained by RF and NB current drive techniques, may be obtained. (author)

The Advanced Divertor and RF Tokamak Experiment (ADX) is a design concept for a compact high-field tokamak that would address boundary plasma and plasma-material interaction physics challenges whose solution is critical for the viability of magnetic fusion energy. This device would have two crucial missions. First, it would serve as a Divertor Test Tokamak, developing divertor geometries, materials and operational scenarios that could meet the stringent requirements imposed in a fusion power plant. By operating at high field, ADX would address this problem at a level of power loading and other plasma conditions that are essentially identical to those expected in a future reactor. Secondly, ADX would investigate the physics and engineering of high-field-side launch of RF waves for current drive and heating. Efficient current drive is an essential element for achieving steady-state in a practical, power producing fusion device and high-field launch offers the prospect of higher efficiency, better control of the current profile and survivability of the launching structures. ADX would carry out this research in integrated scenarios that simultaneously demonstrate the required boundary regimes consistent with efficient current drive and core performance.

This article conveys concerns raised by delegates at the International SAM Conference (Manchester, 2015) regarding how to advance nursing practice in acute medicine. It endeavors to capture the essence of 'how to advance practice' and 'how to integrate advanced practice' within the workforce structures of an acute medicine unit (AMU). It addresses the production of tacit knowledge and the recognition and integration of this to developing the nursing workforce. The current context of NHS efficiencies and recruitment issues emphasize the value of retaining tacit knowledge. Uniquely, this article offers an early conceptual framework through which levels of advancement and potential transition points to advance nursing practice in acute medicine are articulated. Determining how to advance requires identification of prior accomplishments such as, tacit knowledge, experiential learning, CPD, specialist courses and management experience. This requires nurses to make judicious decisions to advance their practice and the distinction between 'amassing experience' and 'career progression'. It aims to stimulate thinking around the practicalities of advancement, the value of tacit knowledge and potential realization through the framework trajectory. PMID:27441313

In the first four years of LHD experiment, several encouraging results have emerged, the most significant of which is that MHD stability and good transport are compatible in the inward shifted axis configuration. The observed energy confinement at this optimal configuration is consistent with ISS95 scaling with an enhancement factor of 1.5. The confinement enhancement over the smaller heliotron devices is attributed to the high edge temperature. We find that plasma with an average beta of 3% is stable in this configuration even though the theoretical stability conditions of Mercier modes and pressure driven low n modes are violated. In the low density discharges heated by NBI and ECR heatings, ITB (internal transport barrier) and an associated high central temperature (> 10 keV) are seen. The radial electric field measured in these discharges is positive (electron root) and expected to play a key role in the formation of the ITB. The positive electric field is also found to suppress the ion thermal diffusivity as predicted by neoclassical transport theory. The width of the externally imposed island (n/m=1/1) is found to decrease when the plasma is collisionless with finite beta and it increases when the plasma is collisional. The ICRF heating in LHD is successful and a high energy tail (up to 500 keV) has been detected for minority ion heating, demonstrating good confinement of the high energy particles. The magnetic field line structure unique to the heliotron edge configuration is confirmed by measuring the plasma density and temperature profiles on the divertor plate. A long pulse (2 minute) discharge with an ICRF power of 0.4 MW has been demonstrated and energy confinement characteristics are almost the same as those in short pulse discharges. (author)

The number of data-based research articles focusing on patient sociodemographic profiling and experience with healthcare practices is still relatively small. One of the reasons for this relative lack of research is that categorizing patients into different demographic groups can lead to significant reductions in sample numbers for homogeneous subgroups. The aim of this article is to identify problems and issues when dealing with big data that contains information at two levels: patient experience of their general practice, and scores received by practices. The Practice Accreditation and Improvement Survey (PAIS) consisting of 27 five-point Likert items and 11 sociodemographic questions is a Royal Australian College of General Practitioners (RACGP)-endorsed instrument for seeking patient views as part of the accreditation of Australian general practices. The data were collected during the 3-year period May 2011-July 2014, during which time PAIS was completed for 3734 individual general practices throughout Australia involving 312,334 anonymous patients. This represents over 60% of practices in Australia, and ∼75% of practices that undergo voluntary accreditation. The sampling method for each general practice was convenience sampling. The results of our analysis show how sociodemographic profiles of Australian patients can affect their ratings of practices and also how the location of the practice (State/Territory, remote access area) can affect patient experience. These preliminary findings can act as an initial set of results against which future studies in patient experience trends can be developed and measured in Australia. Also, the methods used in this article provide a methodological framework for future patient experience researchers to use when dealing with data that contain information at two levels, such as the patient and practice. Finally, the outcomes demonstrate that different subgroups can experience healthcare provision differently, especially

Using analytical mathematical modeling techniques for the system components, an attempt is made to gauge the destabilizing effects in a number of compressor designs. In particular the overhung (or cantilevered) compressor designs and the straddle-mounted (or simply supported) compressor designs are examined. Recommendations are made, based on experiences with stable and unstable compressors, which can be used as guides in future designs. High and low pressure compressors which operate well above their fundamental rotor-bearing lateral natural frequencies can suffer from destructive subsynchronous vibration. Usually the elements in the system design which contribute to this vibration, other than the shafting and the bearings, are the seals (both gas labyrinth and oil breakdown bushings) and the aerodynamic components.
Full Text Available The issue of teaching staff advanced training is paid much attention in many countries. In the Republic of Moldova progressive professional credits system is used. Credits are scored not only in assigning teaching degrees or issuing a certificate of continuing professional education, but also for teachers’ evaluation at the educational institution. Advanced training of teaching staff in France is provided by various institutions of postgraduate education, university institutes and regional centers of education in order to help teachers to renew their professional knowledge and at the same time to refocus it on the level of consciousness according to the real problems of school and the community. The feature of teaching staff advanced training in France is that it is teachers’ personal matter and duration of all periods of training should come to one year during all professional career. In Finland, teaching staff advanced training is organized directly in schools under aegis of the National Board of Education, the National Centre for Advanced Training in Education, departments of teacher education and other faculties of higher educational institutions on credit system basis. Among the topical forms there are targeted, cascade, common (cooperative teaching and learning by own example. In the UK, advanced training takes place in two models: the course model based on higher educational establishments and school based in-service education. The main purpose of advanced training system is to familiarize teachers with theoretical and practical innovations in educational activities, progressive teaching technologies, and consolidate their skills of independent acquisition of knowledge necessary for their professional development.

Experience was recognised to be a vital source of learning as long ago as 1762 [Emile, Everyman, London, 1993] and reflection on practice experience may be one way forward in addressing nursing's anxieties concerning the practice theory gap. However, despite the acceptance that subjectivity in the process seems inevitable and potentially important, little is understood of the practitioner's experience of practice assessment. Two questionnaires sought the views of specialist community nursing practitioner (SCNP) programme (United Kingdom Central Council for Nursing, Midwifery and Health Visiting (UKCC) 2001) practice teachers (PTs) on the introduction of the portfolio approach to practice assessment. These were distributed to 62 and 76 PTs and the response rates were 32% and 50%, respectively. Responses of those PTs from the three specialisms participating in the piloting of the portfolio approach were compared with those using an existing approach. An action research method was adopted which attempted to use established theory to explain the challenges presented by the introduction of this approach and ultimately to raise the PT group's awareness of assessment issues. Both qualitative and quantitative data were collected and the findings support the use of the portfolio approach to practice assessment. The PT experience of portfolio use was found to be a largely positive one. PTs reported the utility of the portfolio in prompting student self-evaluation of learning. Concerns were expressed by PTs around the quality of portfolio evidence although many felt that it had promoted students' reflection on practice. Inter-PT reliability in practice assessment was identified as a topic for PT continuing professional development. Many sources of evidence, including patient feedback, were used by PTs in their assessment of students although PTs using the portfolio approach used less first-hand experience of students' practice in their assessments of competence, relying more

Abstract Objective: to identify the current state of advanced practice nursing regulation, education and practice in Latin America and the Caribbean and the perception of nursing leaders in the region toward an advanced practice nursing role in primary health care to support Universal Access to Health and Universal Health Coverage initiatives. Method: a descriptive cross-sectional design utilizing a web-based survey of 173 nursing leaders about their perceptions of the state of nursing practice and potential development of advanced practice nursing in their countries, including definition, work environment, regulation, education, nursing practice, nursing culture, and perceived receptiveness to an expanded role in primary health care. Result: the participants were largely familiar with the advanced practice nursing role, but most were unaware of or reported no current existing legislation for the advanced practice nursing role in their countries. Participants reported the need for increased faculty preparation and promotion of curricula reforms to emphasize primary health care programs to train advanced practice nurses. The vast majority of participants believed their countries' populations could benefit from an advanced practice nursing role in primary health care. Conclusion: strong legislative support and a solid educational framework are critical to the successful development of advanced practice nursing programs and practitioners to support Universal Access to Health and Universal Health Coverage initiatives.

Advanced practice nurses (APNs) are integral to cost-effective delivery of health care in large health care organizations. Development of the leadership position of director of advanced practice nurses in a large teaching institution provides leadership to APNs in various settings, contributes to staff satisfaction, facilitates increased professional growth, and provides improved quality and fiscal outcomes. Job satisfaction, productivity, accountability, and communication may be enhanced through implementation of the role of director of advanced practice nursing and a committee structure of APNs, as was found in this academic health system.

A method to create instructive, nonuniform aperture functions using spatial frequency filtering is described. The diffraction from a single slit in the Fresnel limit and the interference from a double slit in the Fraunhofer limit are spatially filtered to create electric field distributions across an aperture to produce apodization, inverse apodization or super-resolution, and apertures with phase shifts across their widths. The diffraction effects from these aperture functions are measured and calculated. The excellent agreement between the experimental results and the calculated results makes the experiment ideal for use in an advanced undergraduate or graduate optics laboratory to illustrate experimentally several effects in Fourier optics.

Experiments with pump limiter modules on several operating tokamaks establish such limiters as efficient collectors of particles and has demonstrated the importance of ballistic scattering as predicted theoretically. Plasma interaction with recycling neutral gas appears to become important as the plasma density increases and the effective ionization mean free path within the module decreases. In limiters with particle collection but without active internal pumping, the neutral gas pressure is found to vary nonlinearly with the edge plasma density at the highest densities studies. Both experiments and theory indicate that the energy spectrum of gas atoms in the pump ducting is non-thermal, consistent with the results of Monte Carlo neutral atom transport calculations. The distribution of plasma power over the front surface of such modules has been measured and appears to be consistent with the predictions of simple theory. Initial results from the latest experiment on the ISX-B tokamak with an actively pumped limiter module demonstrates that the core plasma density can be controlled with a pump limiter and that the scrape-off layer plasma can partially screen the core plasma from gas injection. The results from module pump limiter experiments and from the theory and design analysis of advanced pump limiters for reactors are used to suggest the major features of a definitive, axisymmetric, toroidal belt pump limiter experiment

The dietetics profession lacks a comprehensive definition of advanced-level practice. Using a three-round Delphi study with mailed surveys, expert consensus on four dimensions of advanced-level practice that define advanced practice registered dietitians (RDs) in clinical nutrition was explored. Purposive sampling identified 117 RDs who met advanced-level practice criteria. In round 1, experts rated the essentiality of statements on a 7-point ordinal scale and generated open-ended practice activity statements regarding the following four dimensions of advanced-level practice: professional knowledge, abilities and skills, approaches to practice, roles and relationships, and practice behaviors. Median ratings of 1.0 to 3.0 were defined as essential, 4.0 was neutral, and 5.0 to 7.0 were nonessential. In rounds 2 and 3, experts re-rated statements not reaching consensus by evaluating their previous responses, group median rating, and comments. Consensus was reached when the interquartile range of responses to a statement was ≤2.0. Eighty-five experts enrolled (72.6%); 76 (89.4%) completed all rounds. In total, 233 statements were rated, with 100% achieving consensus; 211 (90.6%) were essential to advanced practice RD clinical practice. Having a master's degree; completing an advanced practice residency; research coursework; and advanced continuing education were essential, as were having 8 years of experience; clinical nutrition knowledge/expertise; specialization; participation in research activities; and skills in technology and communication. Highly essential approaches to practice were systematic yet adaptable and used critical thinking and intuition and highly essential values encompassed professional growth and service to patients. Roles emphasized patient care and leadership. Essential practice activities within the nutrition care process included provision of complex patient-centered nutrition care using application of advanced knowledge/expertise and

The book examines how RESTful systems can be designed and deployed, and what the results are in terms of benefits and challenges encountered in the process. This book is intended for information and service architects and designers who are interested in learning about REST, how it is applied, and how it is being advanced.
Within the Community, protection against the dangers of ionizing radiation is regulated in conformity with the provisions of two Council Directives. One is of general application for all activities involving a hazard arising from ionizing radiation and lays down the basic safety standards for the health protection of the general public and workers against the dangers of ionizing radiation. The other is derived from the abovementioned one and lays down the basic measures for the radiation protection of persons undergoing medical examination or treatment. The Commission, in collaboration with the Spanish Ministerio de Sanidad y Consumo, the Consejo de Seguridad Nuclear and the Centro de Investigaciones Energeticas, Medioambientales y Tecnologicas, organized on 12, 13 and 14 September 1988 in Madrid, the third scientific seminar on the optimization principle (Alara) which is a key element of the two abovementioned Council Directives. The seminar allowed an analysis of the progress made since the previous seminars of 1979 and 1983, in the practical implementation of the optimization principle, in relation to the design and operation of nuclear and industrial installations, natural radioactivity, medical practices and countermeasures. The report contains the 20 original contributions presented and some general considerations on the results of the seminar
This book promotes the experimental mathematics approach in the context of secondary mathematics curriculum by exploring mathematical models depending on parameters that were typically considered advanced in the pre-digital education era. This approach, by drawing on the power of computers to perform numerical computations and graphical constructions, stimulates formal learning of mathematics through making sense of a computational experiment. It allows one (in the spirit of Freudenthal) to bridge serious mathematical content and contemporary teaching practice. In other words, the notion of teaching experiment can be extended to include a true mathematical experiment. When used appropriately, the approach creates conditions for collateral learning (in the spirit of Dewey) to occur including the development of skills important for engineering applications of mathematics. In the context of a mathematics teacher education program, this book addresses a call for the preparation of teachers capable of utilizing mo...

Full Text Available The present research aimed to know the significance of academic training experienced by postgraduate students who are pursuing their studies abroad under the context of a Training Program for Advanced Human Capital promoted by the Government of Chile. A feminist epistemology of situated knowledge was used as methodological framework, and narrative productions were used as technique of data collection. With this approach, the experiences of seven graduate students in Spanish universities, mostly of them beneficiaries of scholarships from Chile, were analyzed. The main findings were: the positive assessment of the experience of studying abroad, the divergent testimonies about these experiences, which based on previous educational trajectories and the socioeconomic level of the professional. These aspects influenced the identifications with the concept of Advanced Human Capital for Chile. Also, for some participants, the Advanced Human Capital is seen as an imposed concept which does not coincide with the real opportunities for the professional practice in the country. Therefore, the participants are sceptical about the possibilities of adequate job insertion in the return to Chile.

We seek funding from NASA for the third year (2005) of the four-year period January 1, 2003 - December 31, 2006 for continued support of the MIT contributions to the multi-national global atmospheric trace species measurement program entitled Advanced Global Atmospheric Gases Experiment (AGAGE). The case for real-time high-frequency measurement networks like AGAGE is very strong and the observations and their interpretation are widely recognized for their importance to ozone depletion and climate change studies and to verification issues arising from the Montreal Protocol (ozone) and Kyoto Protocol (climate). The proposed AGAGE program is distinguished by its capability to measure over the globe at high frequency almost all of the important species in the Montreal Protocol and almost all of the significant non-CO2 gases in the Kyoto Protocol.

Advanced nurse practitioners in the author's emergency department (ED) work autonomously and as part of a team to assess, diagnose and treat patients with unexplained and undiagnosed illnesses and injuries over a 24-hour cycle of care. The complexity of the role in EDs is often not fully understood, and expectations can vary between trusts and between different clinical areas within trusts. This article describes one night shift in the author's ED to explain the complexity of advanced nurse practitioners' roles in this environment. The article focuses on autonomous decision-making skills and the use of advanced clinical skills in the context of evidence-based practice. PMID:27165394

They are working at mental health services and educational setting around Indonesia and yet seem not ready to perform some specific advanced competencies in clinical area. The mastery on mental health assessment, neurochemical perspectives, medical management and psychotherapy have not yet performed by the psychiatric nurse specialist in the clinical area or community.To have those competencies and its performances, therefore the curriculum in a psychiatric nursing graduate program must include advanced courses in physiopsychology, psychopathology, advanced psychopharmacology, neurobehavioral science, advanced mental health assessment, and advanced treatment interventions such as psychotherapy and prescription and management of psychotropic medications as their core and major courses in the curriculum. Those courses should be performed in their clinical practice courses or other related learning experiences. When those qualifications are met, then they are competent to be called advanced psychiatric nurse.As advanced practice registered nurses, the advanced psychiatric nurses should be able to demonstrate their direct expertise and roles in advanced mental health assessment, diagnostic evaluation, psychopharmacology management, psychotherapy with individuals, group and families, case management, millieu management, liason and counselling from prevention, promotion until psychiatric rehabilitation. Meanwhile the skill such as psycho-education, teaching, unit management, research and staff development can be added as their indirect roles.

Project-Based Learning (PBL) has been implemented in the first year of the Industrial Engineering and Management programme at the University of Minho, Portugal, since 2004/2005. The purpose of this paper is to analyse and discuss teachers' experiences in PBL in this programme and to explore its implications for student learning and for teaching practices in higher education. For data collection, the research method used was written narratives to these teachers, at the end of the PBL semester. Findings suggest that teachers express a positive view of PBL as a learning approach. They identify student motivation and engagement, along with a better understanding of the application of concepts in real-life situations, as important outcomes of the project for students. Besides this, teachers also highlight the importance of the development of transversal skills by students throughout the project. Recommendations for future work and implications for practice will also be discussed.

This communication describes an optical hands-on fiber laser experiment aimed at advanced college courses. Optical amplifiers and laser sources represent very important optical devices in numerous applications ranging from telecommunications to medicine. The study of advanced photonics experiments is particularly relevant at undergraduate and master level. This paper discusses the implementation of an optical fiber laser made with a cavity built with two tunable Bragg gratings. This scheme allows the students to understand the laser working principles as a function of the laser cavity set-up. One or both of the gratings can be finely tuned in wavelength through applied stress; therefore, the degree of spectral mismatch of the two gratings can be adjusted, effectively changing the cavity feedback. The impact of the cavity conditions on the laser threshold, spectrum and efficiency is analyzed. This experiment assumes that in a previous practice, the students should had already characterized the erbium doped fiber in terms of absorption and fluorescent spectra, and the spectral gain as a function of pump power.
The first proposal for plasma based accelerators was suggested by 1979 by Tajima and Dawson. Since then there has been a tremendous progress both theoretically and experimentally. The theoretical progress is particularly due to the growing interest in the subject and to the development of more accurate numerical codes for the plasma simulations (especially particle-in-cell codes). The experimental progress follows from the development of multi-terawatt laser systems based on the chirped-pulse amplification technique. These efforts have produced results in several experiments world-wide, with the detection of accelerated electrons of tens of MeV. The peculiarity of these advanced accelerators is their ability to sustain extremely large acceleration gradients. In the conventional radio frequency linear accelerators (RF linacs) the acceleration gradients are limited roughly to 100 MV/m; this is partially due to breakdown which occurs on the walls of the structure. The electrical breakdown is originated by the emission of the electrons from the walls of the cavity. The electrons cause an avalanche breakdown when they reach other metal parts of the RF linacs structure

Introduction: Advanced practice (AP) is of increasing interest to many radiation therapists (RTs) both nationally and internationally. In New Zealand, initial research (2005–2008) showed strong support for the development of an AP role for medical radiation technologists (MRTs). Here, we report on a nationwide survey in which RTs validated and prioritised nine AP profiles for future development. Methods: All registered RTs in New Zealand (n = 260) were invited to take part in a survey in December 2011; 73 of whom returned a complete response. Results: RTs supported the implementation of AP roles in New Zealand and the requirement of a Master's degree qualification to underpin clinical knowledge. Most RTs endorsed the criteria attributed to each of the nine proposed AP profiles. The study identified that activities may qualify as either advanced practice or standard practice depending on the department. All participants agreed that an advanced practitioner should be a leader in the field, able to initiate and facilitate future developments within as well as outside this specific role. Acceptance of the AP roles by RTs and other health professionals as well as the availability of resources for successful implementation, were concerns expressed by some RTs. Conclusion: The authors recommend (1) the development of one scope of practice titled ‘advanced practitioner’ with generic and specialist criteria for each profile as the future career pathway, (2) promotion and support for the AP pathway by the New Zealand Institute of Medical Radiation Technology and the New Zealand Medical Radiation Technologists Board

The Advanced Colloids Experiment is being conducted on the International Space Station (ISS) using the Light Microscopy Module (LMM) in the Fluids Integrated Rack (FIR). Work to date will be discussed and future plans and opportunities will be highlighted. The LMM is a microscope facility designed to allow scientists to process, manipulate, and characterize colloidal samples in micro-gravity where the absence of gravitational settling and particle jamming enables scientists to study such things as:a.The role that disordered and ordered-packing of spheres play in the phase diagram and equation of state of hard sphere systems,b.crystal nucleation and growth, growth instabilities, and the glass transition, c.gelation and phase separation of colloid polymer mixtures,d.crystallization of colloidal binary alloys,e.competition between crystallization and phase separation,f.effects of anisotropy and specific interactions on packing, aggregation, frustration and crystallization,g.effects of specific reversible and irreversible interactions mediated in the first case by hybridization of complementary DNA strands attached to separate colloidal particles,h.Lock and key interactions between colloids with dimples and spheres which match the size and shape of the dimples,i.finding the phase diagrams of isotropic and interacting particles,j.new techniques for complex self-assembly including scenarios for self-replication, k.critical Casimir forces,l.biology (real and model systems) in microgravity,m.etc. By adding additional microscopy capabilities to the existing LMM, NASA will increase the tools available for scientists that fly experiments on the ISS enabling scientists to observe directly what is happening at the particle level. Presently, theories are needed to bridge the gap between what is being observed (at a macroscopic level when photographing samples) with what is happening at a particle (or microscopic) level. What is happening at a microscopic level will be directly
Full Text Available Background. Whilst placement supervision and clinical education programmes are of significant value in shaping the behaviours of undergraduate healthcare students, appropriate provisions which are efficacious to the learner are somewhat lacking, particularly for students studying on UK MPharm programmes. Objectives. To explore and explain the value of placement supervision to the personal development and employability of undergraduate pharmacy students. Methods. Students participated in a week long community pharmacy pilot programme, a result of a collaborative effort between the School of Pharmacy and Life Sciences and a small consortium of community pharmacies. Students and stakeholders were asked to evaluate their experiences via separate questionnaires which had been developed to elicit views and attitudes. Key Findings. Feedback from students and stakeholders towards the experience was overwhelmingly positive with multiple benefits being reported. Of particular prominence was the emphasis in student feedback on the value of placement supervision to their professional and personal development. Findings were indicative of a development in clinical practice proficiencies, core skills, and improvement in decision-making practice. Conclusions. The benefits of clinical supervision to the professional and personal development of MPharm students are well documented, although attracting professional pharmacy supervisors is proving a problematic task for educational providers in the UK.

The addition of advanced practice providers (APPs; nurse practitioners and physician assistants) to a pediatric cardiac intensive care unit (PCICU) team is a health care innovation that addresses medical provider shortages while allowing PCICUs to deliver high-quality, cost-effective patient care. APPs, through their consistent clinical presence, effective communication, and facilitation of interdisciplinary collaboration, provide a sustainable solution for the highly specialized needs of PCICU patients. In addition, APPs provide leadership, patient and staff education, facilitate implementation of evidence-based practice and quality improvement initiatives, and the performance of clinical research in the PCICU. This article reviews mechanisms for developing, implementing, and sustaining advance practice services in PCICUs. PMID:26714997

Over the past 20 years health care reform has influenced the development of advanced level practitioner roles and expectations. How advanced level practitioners work to survive the highly stimulating, yet sometimes overwhelming aspects of balancing high quality provision with political reform agendas, amidst economic constraint is considered. Transformational approaches (encompassing education and practice led service development) can provide, promote and 'provoke' a harnessing of complex issues workplace environment to produce creative solutions. Transformational Practice Development provides a structured, rigorous, systematic approach that practitioners, teams and health care consumers alike can utilise to achieve skills and attributes needed for successful innovation. The authors present case study materials from action orientated locally delivered Practice Development, as a complex strategic intervention approach to influence and promote advanced level practice expertise. Initiated through facilitation of transformational leadership, and resultant team based improvements, we present how strategic collaborative processes can harness work chaos and complexity to provide sustainable and productive workplace cultures of effectiveness.

Introduction: This article presents the outcome and recommendations following the second stage of a role development project conducted on behalf of the New Zealand Institute of Medical Radiation Technology (NZIMRT). The study sought to support the development of profiles and criteria that may be used to formulate Advanced Scopes of Practice for the profession. It commenced in 2011, following on from initial research that occurred between 2005 and 2008 investigating role development and a possible career structure for medical radiation technologists (MRTs) in New Zealand (NZ). Methods: The study sought to support the development of profiles and criteria that could be used to develop Advanced Scopes of Practice for the profession through inviting 12 specialist medical imaging groups in NZ to participate in a survey. Results: Findings showed strong agreement on potential profiles and on generic criteria within them; however, there was less agreement on specific skills criteria within specialist areas. Conclusions: The authors recommend that one Advanced Scope of Practice be developed for Medical Imaging, with the establishment of generic and specialist criteria. Systems for approval of the overall criteria package for any individual Advanced Practitioner (AP) profile, audit and continuing professional development requirements need to be established by the Medical Radiation Technologists Board (MRTB) to meet the local needs of clinical departments. It is further recommended that the NZIMRT and MRTB promote and support the need for an AP pathway for medical imaging in NZ

Full Text Available Public input is often sought as part of the biosafety decision making. Information and communication about the advances in biotechnology are part of the first step to engagement. This step often relies on the developers and introducers of the particular innovation, for example an industry funded website has hosted various authorities to respond to questions from the public. Alternative approaches to providing information have evolved, as demonstrated in Sub Saharan Africa where NGOs and associations play this role in some countries and subregions. Often times those in the public who choose to participate in engagement opportunities have opinions about the overall biosafety decision process. Case by case decisions are made within defined regulatory frameworks, however, and in general regulatory consultation does not provide the opportunity for input to the overall decision making process. The various objectives on both sides of engagement can make the experience challenging; there are no clear metrics for success. The situation is challenging because public input occurs within the context of the local legislative framework, regulatory requirements, and the peculiarities of the fairly recent biosafety frameworks, as well as of public opinion and individual values. Public engagement may be conducted voluntarily, or may be driven by legislation. What can be taken into account by the decision makers, and therefore what will be gathered and the timing of consultation, also may be legally defined. Several practical experiences suggest practices for effective engagement within the confines of regulatory mandates: (1 utilizing a range of resources to facilitate public education and opportunities for understanding complex technologies; (2 defining in advance the goal of seeking input; (3 identifying and communicating with the critical public groups from which input is needed; (4 using a clearly defined approach to gathering and assessing what will be used

This step often relies on the developers and introducers of the particular innovation, for example, an industry-funded website has hosted various authorities to respond to questions from the public. Alternative approaches to providing information have evolved, as demonstrated in sub-Saharan Africa where non-governmental organizations and associations play this role in some countries and subregions. Often times, those in the public who choose to participate in engagement opportunities have opinions about the overall biosafety decision process. Case-by-case decisions are made within defined regulatory frameworks, however, and in general, regulatory consultation does not provide the opportunity for input to the overall decision-making process. The various objectives on both sides of engagement can make the experience challenging; there are no clear metrics for success. The situation is challenging because public input occurs within the context of the local legislative framework, regulatory requirements, and the peculiarities of the fairly recent biosafety frameworks, as well as of public opinion and individual values. Public engagement may be conducted voluntarily, or may be driven by legislation. What can be taken into account by the decision makers, and therefore what will be gathered and the timing of consultation, also may be legally defined. Several practical experiences suggest practices for effective engagement within the confines of regulatory mandates: (1) utilizing a range of resources to facilitate public education and opportunities for understanding complex technologies; (2) defining in advance the goal of seeking input; (3) identifying and communicating with the critical public groups from which input is needed; (4) using a clearly defined approach to gathering and

Many countries are seeking to improve health care delivery by reviewing the roles of health professionals, including nurses. Developing new and more advanced roles for nurses could improve access to care in the face of a limited or diminishing supply of doctors and growing health care demand. The development of new nursing roles varies greatly from country to country. The United States and Canada established "nurse practitioners" (NPs) in the mid-1960s. The United Kingdom and Finland also have a long experience in using different forms of collaboration between doctors and nurses. In other countries, such as Australia, NPs were endorsed more recently in 2000. In France, Belgium, or Singapore, the formal recognition of advanced practice nurses is still in its infancy, whereas in other countries, such as Japan or China, advanced practice nurses are not licensed titles. The aims of this article were to define precisely what is meant by the term "advanced practice nurse (APN)," describe the state of development of APN roles, and review the main factors motivating the implementation of APN in different countries. Then, we examine the main factors that have hindered the development of APN roles. Finally, we explain the need for advanced practice roles in geriatrics. PMID:27321868

This descriptive study replicates and extends previous research on advanced practice RNs and the (1) reference resources available to them at the point of care, (2) resources they use to inform their clinical practice, and (3) resources they are accessing from handheld electronic devices such as PDAs, smartphones, and tablet computers during practice. These elements formed the purpose of the current study. A sample of advanced practice RNs from Texas Public Health Region 11 was surveyed. Available resources were current journals appropriate to setting and current clinical guidelines. These advanced practice RNs "always or frequently" based their professional practice on personal experience of caring for patients/clients over time, information learned in college/university, and information learned about each patient/client as an individual. Responses for Hispanic respondents as well as electronic device users were similar. Content and features accessed daily by handheld computer devices were reference materials, e-mail, address/phonebook, Internet access other than e-mail, calendar/date book, alarm/reminder, calculator, and memo pad. Software installed on handheld devices and used daily included drug references, medical text/reference book, medical math/formula calculator, practice guidelines, and language translator/dictionary. Respondents who did not report using handheld devices at work were older, had more years in advanced practice nursing, and were more likely to work in a hospital, birthing center, or institution such as a prison, school, or military facility. There was no difference in resource or electronic device use by Hispanic advanced practice RNs. Electronic resources for practice are growing and being used by advanced practice RNs. Consideration should be given to incorporating evaluation and implementation of electronic clinical resources into advanced practice RN educational programs. Future research should include greater detail about the origin of

Advanced practice for radiation therapists has been a part of the international landscape for several years; however formal implementation into the Australian health care system is yet to happen. Despite this, three short course radiation therapy advanced practitioner programs have been established by an Australian tertiary institution in response to clinical service needs at several organisations. This paper describes the rationale for curriculum design and development of the program materials, the small-scale implementation of the programs at pilot sites, and the evolution of the curriculum to be available to registered radiation therapists nationally. Each program has been designed around a specific clinical role, where flexibility of delivery to busy practitioners was central to the decision to offer them via distance education. The curriculum comprises theoretical units of study which run in parallel to and underpin clinical practice units, where advanced competence in the specific area of practice is overseen by an experienced radiation oncologist mentor. Given the nature of the disparate clinical services requiring an advanced radiation therapy practitioner, the workplace learning component of the course is individually negotiated at a local level. Outcomes suggest that the flexible clinically based training underpinned by a distance education academic curriculum is able to support the development of advanced radiation therapy practitioners responsive to local service need, and ultimately may improve the patient experience

Experiments are underway to tune the shock timing of capsule implosions on the National Ignition Facility (NIF). These experiments use a modified cryogenic hohlraum geometry designed to precisely match the performance of ignition hohlraums. The targets employ a re-entrant Au cone to provide optical access to multiple shocks as they propagate in the liquid deuterium-filled capsule interior. The strength and timing of all four shocks is diagnosed with VISAR (Velocity Interferometer System for Any Reflector). Experiments are now routinely conducted in a mirrored keyhole geometry, which allows for simultaneous diagnosis of the shock timing at both the hohlraum pole and equator. Further modifications are being made to improve the surrogacy to ignition hohlraums by replacing the standard liquid deuterium (D2) capsule fill with a deuterium-tritium (DT) ice layer. These experiments will remove any possible surrogacy difference between D2 and DT as well as incorporate the physics of shock release from the ice layer, which is absent in current experiments. Experimental results and comparisons with numerical simulation are presented.

Most advanced process control systems are based on Model Predictive Control (MPC). In this paper we discuss three critical issues for the practical implementation of linear MPC for process control applications. The rst issue is related to oset free control and disturbance models; the second issue......-regulator structure. It enables oset free control; it can be computed eciently on-line using several optimization algorithms; and accommodates soft constraint for the outputs and for shaping the set-point tracking penalty function. We report selected observations using this implementation and discuss their practical...... models and integration of the innovation errors. If the disturbances increases, oset-free control cannot be achieved without violation of process constraints. A target calculation function is used to calculate the optimal achievable target for the process. The use of soft constraints for process output...

We report on a study of the phase camera, which is a frequency selective wave-front sensor of a laser beam. This sensor is utilized for monitoring sidebands produced by phase modulations in a gravitational wave (GW) detector. Regarding the operation of the GW detectors, the laser modulation/demodulation method is used to measure mirror displacements and used for the position controls. This plays a significant role because the quality of controls affect the noise level of the GW detector. The phase camera is able to monitor each sideband separately, which has a great benefit for the manipulation of the delicate controls. Also, overcoming mirror aberrations will be an essential part of Advanced Virgo (AdV), which is a GW detector close to Pisa. Especially low-frequency sidebands can be affected greatly by aberrations in one of the interferometer cavities. The phase cameras allow tracking such changes because the state of the sidebands gives information on mirror aberrations. A prototype of the phase camera has been developed and is currently tested. The performance checks are almost completed and the installation of the optics at the AdV site has started. After the installation and commissioning, the phase camera will be combined to a thermal compensation system that consists of CO2 lasers and compensation plates. In this paper, we focus on the prototype and show some limitations from the scanner performance.
The Advanced Light Source (ALS) has been operational for users since October 1993 when white light from a bend magnet was delivered to the Center for X-Ray Optic close-quote s (CXRO) x-ray microprobe end station. Since then, the ALS has installed and commissioned three undulators and their beamlines (including monochromators and post-monochromator focusing optics), and eight bend-magnet beamlines, including one dedicated to machine diagnostics. Apart from one serious outage, when scheduled beam was not available to users for 17 days, the ALS has enjoyed remarkable operating statistics, with typically 95% of scheduled beam time delivered to the users. Beam quality has also been very good. With a vertical emittance measured at 0.06 nm-rad, the electron beam is kept stable to about one-tenth of its transverse dimensions, in the face of changing error fields in the insertion devices (as their main fields are varied), temperature variations, and floor vibration. The longitudinal motion of the beam, which leads to an increase in the electron beam energy spread and thence to a degradation of the undulator spectra, has recently been brought under control by the addition of an innovative feedback system. This paper focuses on those aspects of electron beam stability that we find most affect the ALS users: beam size and position, and energy spread. copyright 1996 American Institute of Physics

The Remote Glow Discharge Experiment (RGDX) is a DC discharge plasma with variable pressure, end-plate voltage and externally applied axial magnetic field. While the experiment is located at PPPL, a webcam displays the live video online. The parameters (voltage, magnetic field and pressure) can be controlled remotely in real-time by opening a URL which shows the streaming video, as well as a set of Labview controls. The RGDX is designed as an outreach tool that uses the attractive nature of a plasma in order to reach a wide audience and extend the presence of plasma physics and fusion around the world. In March 2014, the RGDX was made publically available and, as of early July, it has had approximately 3500 unique visits from 107 countries and almost all 50 US states. We present recent upgrades, including the ability to remotely control the distance between the electrodes. These changes give users the capability of measuring Paschen's Law remotely and provides a comprehensive introduction to plasma physics to those that do not have access to the necessary equipment.
The diagnostics functions of neutron measurements are reviewed as well as the roles played by neutron yield monitors, cameras and spectrometers. The importance of recent developments in neutron emission spectroscopy (NES) diagnostics is emphasized.

This article considers the reasons for the development of advanced practice roles among nurses and other healthcare professions. It explores the implications of financial constraints, consumer preferences and the development of new healthcare services on the reorganization of professional boundaries. It makes use of Sir Isaac Newton's three laws of motion to demonstrate how professional development in nursing has taken place in response to a number of external influences and demands. It also considers the significance of skill mix for the nursing profession, in particular the development and likely expansion of the physician assistant role. The application of different professionals and grades within a healthcare team or organization is central to the Government's Agenda for Change proposals and nurses have successfully adopted a number of roles traditionally performed by doctors. Nurses have demonstrated that they are capable of providing high quality care and contributing directly to positive patient outcome. Advanced nursing roles should not only reflect the changing nature of healthcare work, they should also be actively engaged in reconstructing healthcare boundaries. PMID:18773586
Consultant and advanced practice are relatively new concepts in radiography. There is evidence to show that as the career progression framework is being adopted the numbers of consultant and advanced practitioners in radiography are growing with the latter growing at a faster rate. The article considers the concept of advanced and consultant practice and the education requirements to support development. Preparation for an advanced practice role begins at the practitioner stage. Masters' level programmes are available to support the development of advanced practice. Education needs to be flexible as new advanced practice roles emerge. It is necessary to take practitioners beyond a defined modality to include leadership and people skills. These are essential for those aspiring to become consultants. Consultants require a high level of clinical knowledge for expert practice but also strategic vision and interpersonal intelligence to facilitate leadership and practice innovation. A model for developing leadership skills for consultants focussing on competence, confidence and capacity is proposed

Experience in other industries has shown that digital technology can provide substantial benefits in terms of performance and reliability. However, the U.S. nuclear power industry has been slow to adopt the technology extensively in its instrumentation and control (I&C) applications because of inhibiting factors such as regulatory uncertainty, insufficient technological experience base, implementation complexity, limited availability of nuclear-qualified products and vendors, and inadequate definition of modernization cost recapture. Although there have been examples of digital technology usage in the nuclear power industry, challenges to the qualification of digital technology for high-integrity nuclear power plant (NPP) applications have severely constrained more widespread progress in achieving the benefits that are possible through the transition to digital. The U.S. Department of Energy (DOE) Office of Nuclear Energy (NE) established the Advanced Sensors and Instrumentation (ASI) technology area under the Nuclear Energy Enabling Technologies (NEET) Program to coordinate the instrumentation and controls (I&C) research across DOE NE and to identify and lead efforts to address common needs. As part of the NEET ASI research program, the Digital Technology Qualification project was established. Under this project, the Oak Ridge National Laboratory (ORNL) is leading the investigation into mitigation of digital common-cause failure (CCF) vulnerabilities for nuclear-qualified applications. This technical report documents updated and expanded findings from research activities by ORNL. Specifically, the report describes CCF experience in the nuclear and nonnuclear industries, identifies the state of the practice for CCF mitigation through key examples, and presents conclusions from the determination of knowledge gaps.
In this paper we describe several detection techniques that can be employed to study cosmic ray properties and carry out training activities at high school and undergraduate level. Some of the proposed devices and instrumentation are inherited from professional research experiments, while others were especially developed and marketed for educational cosmic ray experiments. The educational impact of experiments in cosmic ray physics in high-school or undergraduate curricula will be exploited through various examples, going from simple experiments carried out with small Geiger counters or scintillation devices to more advanced detection instrumentation which can offer starting points for not trivial research work.

The quality movement, that has had in recent years a dramatic impact on all industrial sectors, has recently reached the system and software industry. Although some concepts of quality management, originally developed for other product types, can be applied to software, its specificity as a product which is developed and not produced requires a special approach. This paper introduces a quality paradigm specifically tailored on the problem of the systems and software industry. Reuse of products, processes and experiences originating from the system life cycle is seen today as a feasible solution to the problem of developing higher quality systems at a lower cost. In fact, quality improvement is very often achieved by defining and developing an appropriate set of strategic capabilities and core competencies to support them. A strategic capability is, in this context, a corporate goal defined by the business position of the organization and implemented by key business processes. Strategic capabilities are supported by core competencies, which are aggregate technologies tailored to the specific needs of the organization in performing the needed business processes. Core competencies are non-transitional, have a consistent evolution, and are typically fueled by multiple technologies. Their selection and development requires commitment, investment and leadership. The paradigm introduced in this paper for developing core competencies is the Quality Improvement Paradigm which consists of six steps: (1) Characterize the environment, (2) Set the goals, (3) Choose the process, (4) Execute the process, (5) Analyze the process data, and (6) Package experience. The process must be supported by a goal oriented approach to measurement and control, and an organizational infrastructure, called Experience Factory. The Experience Factory is a logical and physical organization distinct from the project organizations it supports. Its goal is development and support of core competencies

Albert Einstein may be best known as the wire-haired whacky physicist who gave us the theory of relativity, but that's just one facet of this genius' contribution to human knowledge and modern science. As Jozsef Illy expertly shows in this book, Einstein had an eminently practical side as well. As a youth, Einstein was an inveterate tinkerer in the electrical supply factory his father and uncle owned and operated. His first paid job was as a patent examiner. Later in life, Einstein contributed to many inventions, including refrigerators, microphones, and instruments for aviation. In published papers, Einstein often provided ways to test his theories and fundamental problems of the scientific community of his times. He delved deeply into a variety of technological innovations, most notably the gyrocompass, and consulted for industry in patent cases and on other legal matters. Einstein also provided explanations for common and mundane phenomena, such as the meandering of rivers. In these and other hands-on exam...

Advances in computer technology provide a wide range of applications which are revolutionizing the practice of medicine. The development of new software for the office creates a web of communication among physicians, staff members, health care facilities and associated agencies. This provides the physician with the prospect of a paperless office. At the other end of the spectrum, the development of 3D work stations and software based on computational chemistry permits visualization of protein molecules involved in disease. Computer assisted molecular modeling has been used to construct working 3D models of lens alpha-crystallin. The 3D structure of alpha-crystallin is basic to our understanding of the molecular mechanisms involved in lens fiber cell maturation, stabilization of the inner nuclear region, the maintenance of lens transparency and cataractogenesis. The major component of the high molecular weight aggregates that occur during cataractogenesis is alpha-crystallin subunits. Subunits of alpha-crystallin occur in other tissues of the body. In the central nervous system accumulation of these subunits in the form of dense inclusion bodies occurs in pathological conditions such as Alzheimer's disease, Huntington's disease, multiple sclerosis and toxoplasmosis (Iwaki, Wisniewski et al., 1992), as well as neoplasms of astrocyte origin (Iwaki, Iwaki, et al., 1991). Also cardiac ischemia is associated with an increased alpha B synthesis (Chiesi, Longoni et al., 1990). On a more global level, the molecular structure of alpha-crystallin may provide information pertaining to the function of small heat shock proteins, hsp, in maintaining cell stability under the stress of disease.

Internationally, the delivery of health services has shifted from secondary to primary care, necessitating an exponential growth of the nursing workforce and expansion of the nursing role in general practice. This growth, and the subsequent need to develop this workforce, has created a need to expose undergraduate nurses to general practice nursing as a viable career option. Concurrently, universities are struggling to find sufficient clinical places for their undergraduate students to gain clinical experience. It is logical, therefore, to increase the number of undergraduate nursing student placements in general practice. Through qualitative research methods, this paper seeks to explore the experiences of practice nurses mentoring undergraduate students on clinical placements within the general practice setting. Findings are presented in the following three themes: (1) Promoting Practice Nursing: We really need to get students in, (2) Mentoring future co-workers: Patience and reassurance, and (3) Reciprocity in learning: It's a bit of a two way street, which show the benefits of such placements. Clinical placements in general practice settings can be mutually beneficial in terms of providing quality teaching and learning experiences for students. Conversely, the experience provides an impetus for practice nurses to maintain currency of their clinical skills and knowledge through mentoring student nurses. PMID:21908081

Several models of scheduling have been documented in the literature, including the traditional model, the carve-out model, and the advanced access model. We describe the implementation of the advanced access model in our clinic, which has been very successful. Advanced access has decreased third next available appointments to less than seven days for many of our providers and has increased individual primary care physician continuity for 40% of our providers. Interestingly, we had no gains in patient satisfaction, which is consistent with other previously published studies on advanced access. PMID:26665471

This article reviews the research and interventions that have grown up around a model of psychological well-being (Ryff, 1989) generated more than two decades ago to address neglected aspects of positive functioning, such as purposeful engagement in life, realization of personal talents and capacities, and enlightened self-knowledge. The conceptual origins of this formulation are revisited and scientific products emerging from six thematic areas are examined: (1) how well-being changes across adult development and later life, (2) what are the personality correlates of well-being, (3) how well-being is linked with experiences in family life, (4) how well-being relates to work and other community activities, (5) what are the connections between well-being and health, including biological risk factors, (6) and via clinical and intervention studies, how psychological well-being can be promoted for ever greater segments of society. Together, these topics illustrate flourishing interest across diverse scientific disciplines in understanding adults as striving, meaning-making, proactive organisms who are actively negotiating the challenges of life. A take-home message is that increasing evidence supports the health protective features of psychological well-being in reducing risk for disease and promoting length of life. A recurrent and increasingly important theme is resilience – the capacity to maintain or regain well-being in the face of adversity. Implications for future research and practice are considered.

At 2 wastewater treatment plants in Tyrolia, Austria, large-scale experiences with the acidification of primary sludge were made. The operational results are presented and analysed critically with special focus on nutrient removal. The economical calculations derived thereof show that in case of a newly constructed wastewater treatment plant total costs including investment and operation can be reduced by approximately 5%. In case of an existing plant which is adapted to new demands the financial benefits can be even higher, because of the frequent possibility to use existing units for acidification. (orig.) [German] Auf 2 Klaeranlagen in Tirol, Oesterreich, wurden grosstechnische Erfahrungen mit dem gezielten Einsatz von versaeuertem Primaerschlamm gesammelt. Die Betriebsergebnisse werden vorgestellt und kritisch analysiert, wobei insbesondere auf die Auswirkungen bezueglich Naehrstoffelimination naeher eingegangen wird. Die daraus abgeleiteten Wirtschaftlichkeitsberechnungen zeigen, dass sich bei einem Klaeranlagen-Neubau die Gesamtkosten aus Investitionen und Betrieb auf einfache Weise um ca. 5% vermindern lassen. Bei Umbauten von Klaeranlagen ist die Wirtschaftlichkeit oft noch wesentlich hoeher, da haeufig bestehende Anlagenteile zur Versaeuerung genutzt werden koennen.

Full Text Available While facilitating the first practice development school for our local healthcare authorities in Nova Scotia, Canada, recently, I was simultaneously preparing for my second hip replacement. Focusing workshop participants on the principles of practice development, collaboration, inclusion and participation, I wondered if, in my upcoming journey through the healthcare system, I would experience the processes and outcomes we were promoting in the school. I would like to share this commentary as a reflection of my practice development experience as a patient. Overall, I received care that was inclusive and collaborative – as well as care that was provider focused and system driven. It goes without saying that as a patient, I felt valued when I was included and felt part of the team when my wishes and expectations were taken into consideration. For me, inclusion in care correlates with valuing that patient as a participant in their care journey, as set out by practice development principle 6 (Manley, McCormack and Wilson, 2008 (Table 1. My recent healthcare experience has led me to reflect further on the principles of practice development and its implications and challenges for local healthcare authorities. For example, my anaesthetist comes to mind as embodying practice development principles 2, 4, 6 and 8. The anaesthetist supported my wishes surrounding narcotics, and provided research- and practice-based evidence for each of his actions. Although the offering of additional narcotics is routine practice in hip surgery, I did not want this, so we discussed my expectations and developed a plan together that reflected my wishes. He actually chatted throughout the entire two-hour procedure. I was pleasantly surprised when he told me he provides care that focuses on the patient (practice development principle 1. Nevertheless, inconsistencies in the attention to person-centred practices across the microsystem reminded me that the system is not yet set

Since 1996, Interlink Community Cancer Nurses have been using reflective practice as a team to share knowledge and experience amongst peers. The use of reflective practice enables the nurse to examine decision-making in patient situations and uncover the knowledge and artistry that is embedded in nursing practice. This article describes how reflection is practised by specialist cancer nurses to advance the quality of caregiving. The use of a structured framework for reflection which incorporates ways of knowing in nursing is an essential feature of the Interlink model for reflection. The development of a process for reflection within the Interlink program has at times been challenging. However, the Interlink nurses' experience with reflection is believed to be critical to the ongoing development of the program and the individual nurse. Interlink nurses have found that guided reflection, the creation of an environmental milieu for reflection and personal knowing, and self-evaluation are critical to the process of becoming a self-reflective practitioner.

Full Text Available Herb-herb combinations have been used in Chinese medicine practice for thousands of years, yet scientific evidence of their therapeutic benefits is lacking. With increasing interest in shifting from the one-drug-one-target paradigm to combination therapy or polypharmacy to achieve therapeutic benefits for a number of diseases, there is momentum to explore new knowledge by tapping the past empirical experiences of herb-herb combinations. This review presents an overview of the traditional concept and practice of herb-herb combination in Chinese medicine, and highlights the available scientific and clinical evidence to support the combined use of herbs. It is hoped that such information would provide a lead for developing new approaches for future therapeutic advancement and pharmaceutical product development. Very likely modern technologies combined with innovative research for the quality control of herbal products, identification of active components and understanding of the molecular mechanism, followed by well-designed animal and clinical studies would pave the way in advancing the wealth of empirical knowledge from herb-herb combination to new therapeutic modalities.

The United States Department of Energy’s Advanced Gas Reactor (AGR) Fuel Development and Qualification Program will be irradiating eight particle fuel tests in the Advanced Test Reactor (ATR) located at the newly formed Idaho National Laboratory (INL) to support development of the next generation Very High Temperature Reactor (VHTR) in the United States. The ATR has a long history of irradiation testing in support of reactor development and the INL has been designated as the new United States Department of Energy’s lead laboratory for nuclear energy development. These AGR fuel experiments will be irradiated over the next ten years to demonstrate and qualify new particle fuel for use in high temperature gas reactors. The experiments will be irradiated in an inert sweep gas atmosphere with on-line temperature monitoring and control combined with on-line fission product monitoring of the sweep gas. The final design phase has just been completed on the first experiment (AGR-1) in this series and the support systems and fission product monitoring system that will monitor and control the experiment during irradiation. This paper discusses the development of the experimental hardware and support system designs and the status of the experiment.

The Detector for Advanced Neutron Capture Experiments (DANCE) has been used for extensive studies of neutron capture, gamma decay, photon strength functions, and prompt and delayed fission-gamma emission. Despite these successes, the potential measurements have been limited by the data acquisition hardware. We report on a major upgrade of the DANCE data acquisition that simultaneously enables strait-forward coupling to auxiliary detectors, including high-resolution high-purity germanium detectors and neutron tagging array. The upgrade will enhance the time domain accessible for time-of-flight neutron measurements as well as improve the resolution in the DANCE barium fluoride crystals for photons
Improved water chemistry control is essential to: Minimize materials degradation (e.g., stress corrosion cracking (SCC) of steam generator (SG) tubes, primary water stress corrosion cracking (PWSCC), corrosion of fuel); Minimize corrosion product transport (e.g., transport into the SGs where it can foul tube surfaces and create crevice environments for the concentration of corrosive impurities, transport and deposition on the fuel); and, Minimize dose rates. Water chemistry control must be optimized to provide overall improvement considering the sometimes variant constraints of the goals listed above. New approaches to mitigate materials degradation, reduce corrosion product transport, and minimize plant dose rates are continually sought. The industry needs to address system integrity issues through application of promising, innovative chemistry initiatives; focusing on long-term integrity and viability while maintaining fuel integrity and minimizing dose rates. This presentation will summarize some of the major initiatives with respect to PWR primary and secondary system chemistry to effectively address these goals, as they pertain to SGs. (author)

The number of credentialed dietetics specialists--approximately 15% of the profession--is proportionately higher than those in other allied health and nursing professions. Credentialed specialists seem to receive greater compensation earlier in their career, but this advantage neutralizes as length of time in the profession increases. A larger proportion of younger registered dietitians (RDs) are specialists, which may mean an increase in supply of specialists in the future. There is considerable interest in creation of health promotion and foodservice management credentials. Consideration should be given to collaborating with other organizations to explore new models of recognition or credentialing for narrow areas of focus. Creating a methodology that can differentiate the tasks and approaches to practice that are unique to advanced practitioners compared with specialists has been a challenge. Prior research has not succeeded in identifying the differences in what advanced practitioners do. Future research to isolate advanced practice must take practice approach into account. A new, research-based, credential for advanced practitioners is possible, or a recognition program for advanced practice RDs could be considered. Precise supply and demand for specialty and advanced practice RDs cannot be measured. Thus, in this technical article, the authors share the available information regarding supply and demand with regard to dietetics specialists and advanced practitioners. It seems there are distinctions among the various levels of practice and recognition of their value to the profession and to the health of the public. PMID:22709861

Recent advances in shock timing experiments and analysis techniques now enable shock measurements to be performed in cryogenic deuterium-tritium (DT) ice layered capsule implosions on the National Ignition Facility (NIF). Previous measurements of shock timing in inertial confinement fusion (ICF) implosions were performed in surrogate targets, where the solid DT ice shell and central DT gas were replaced with a continuous liquid deuterium (D2) fill. These previous experiments pose two surrogacy issues: a material surrogacy due to the difference of species (D2 vs. DT) and densities of the materials used and a geometric surrogacy due to presence of an additional interface (ice/gas) previously absent in the liquid-filled targets. This report presents experimental data and a new analysis method for validating the assumptions underlying this surrogate technique.

Full Text Available Objective: To discuss the experience of sharing an experiential model of education and practice development between two colleges of pharmacy and to provide a framework to guide faculty in this type of collaboration.Case Study: The Ohio State University College of Pharmacy (OSU COP Partner for Promotion (PFP program was developed in response to the need for advancing practice in the community pharmacy setting. After successful implementation of this program, the PFP program design and materials were shared, adapted, and implemented at the University of Utah College of Pharmacy (Utah COP. Collaborating faculty developed a framework based on lessons learned through this experience which proposes key guiding strategies as considerations to address prior to embarking on sharing any aspect of an educational program or model between institutions. Each step of the framework is described and applied to the process followed by The OSU COP and Utah COP in sharing the PFP program. Additional considerations related to transfer of educational models are discussed.Results/Conclusion: Sharing the education model and materials associated with the PFP program between institutions has enhanced experiential opportunities for students and helped develop residency training sites in the community setting. In addition, the relationship between the two colleges has contributed to faculty development, as well as an increase in community pharmacy service development with community pharmacy partners at each institution. It is hoped this experience will help guide collaborations between other colleges of pharmacy to enhance education of future pharmacists while positively impacting pharmacy practice, teaching, and research by faculty.

Chronic low back pain is a common, disabling, and costly condition, and advanced practice registered nurses (APRNs) must carefully evaluate patients before considering long-term opioid therapy as a management strategy. APRNs should refer patients suspected of having a serious condition, or identifiable etiology, for specialist evaluation, as many patients improve with physical therapy, interventional pain management procedures, or surgical intervention. For patients unresponsive to nonopioid treatment, APRNs with an understanding of opioids, and the experience to assess and manage the risks of opioid misuse, abuse, and diversion, may consider long-term opioid therapy as part of a multimodal management plan. Such prescribing necessitates careful patient selection; informed consent; prudent opioid dosing and titration; and monitoring for response to treatment, adverse effects, and aberrant drug-taking behavior. Treatment and regulatory guidelines can assist APRNs in providing safe and effective care to patients with chronic low back pain. PMID:25365050
By 2003, the year the US Department of Energy (DOE) currently predicts a repository will be available, 58 domestic commercial nuclear-power plant units are expected to run out of wet storage space for LWR spent fuel. To alleviate this problem, utilities implemented advances in storage methods that increased storage capacity as well as reduced the rate of generating spent fuel. Those advances include (1) transhipping spent-fuel assemblies between pools within the same utility system, (2) reracking pools to accommodate additional spent-fuel assemblies, (3) taking credit for fuel burnup in pool storage rack designs, (4) extending fuel burnup, (5) rod consolidation, and (6) dry storage. The focus of this paper is on advances in rod consolidation and dry storage. Wet storage continues to be the predominant US spent-fuel management technology, but as a measure to enhance at-reactor storage capacity, the Nuclear Waste Policy Act of 1982 authorized DOE to assist utilities with licensing at-reactor dry storage. Information exchanges with other nations, laboratory testing and modeling, and cask tests cooperatively funded by US utilities and DOE produced a strong technical basis to develop confidence that LWR spent fuel can be stored safely for several decades in both wet and dry modes. Licensed dry storage of spent fuel in an inert atmosphere was first achieved in the US in 1986. Studies are underway in several countries to determine acceptable conditions for storing LWR spent fuel in air. Rod-consolidation technology is being developed and demonstrated to enhance the capacity for both wet and dry storage. Large-scale commercial implementation is awaiting optimization of practical and economical mechanical systems. 22 refs., 1 fig

The Gravity for the Redefinition of the American Vertical Datum (GRAV-D) project, an official policy of the U.S. National Geodetic Survey as of 2007, is working to survey the entire U.S. and its holdings with high-altitude airborne gravimetry. The goal of the project is to provide a consistent, high-quality gravity dataset that will become the cornerstone of a new gravimetric geoid and national vertical datum in 2022. Over the last five years, the GRAV-D project has surveyed more than 25% of the country, accomplishing almost 500 flights on six different aircraft platforms and producing more than 3.7 Million square km of data thus far. This wealth of experience has led to advances in the collection, processing, and evaluation of high-altitude (20,000 - 35,000 ft) airborne gravity data. This presentation will highlight the most important practical and theoretical advances of the GRAV-D project, giving an introduction to each. Examples of innovation include: 1. Use of navigation grade inertial measurement unit data and precise lever arm measurements for positioning; 2. New quality control tests and software for near real-time analysis of data in the field; 3. Increased accuracy of gravity post-processing by reexamining assumptions and simplifications that were inconsistent with a goal of 1 mGal precision; and 4. Better final data evaluation through crossovers, additional statistics, and inclusion of airborne data into harmonic models that use EGM08 as a base model. The increases in data quality that resulted from implementation of the above advances (and others) will be shown with a case study of the GRAV-D 2008 southern Alaska survey near Anchorage, over Cook Inlet. The case study's statistics and comparisons to global models illustrate the impact that these advances have had on the final airborne gravity data quality. Finally, the presentation will summarize the best practices identified by the project from its last five years of experience.

The authors report on the activities of a female consultant with psychosocial orientation acting within the framework of a practising lady paediatrician's medical activities. The paediatrician refers patients or families to the social sciences consultant who studied paedagogics, sociology and psychology and who is so to say part of the paediatric consultation work. This amounts to an approach to an integrated type of treatment. It is an attempt to extend the old therapeutic concept of "disease", which has been mainly directed at cure and at treating the human organism, via practical interaction between various fields of human activity. Paediatric medicine lends itself quite easily to such an approach on the basis of experience collected in the course of time. The authors give a systematised description of the consultant practice, showing the boundary-lines of competencies. A few practical cases are outlined. The authors consider this set-up as an attempt to effect structural improvements of general medical care. PMID:4059448

The nurse practitioner focus has been evolving from a medical to a nursing orientation since the inception of the role in 1965. The purpose of this study was to examine relationships between role attitudes and values, confidence about practice knowledge and skills, and orientation to a medical or nursing model to guide practice. A national random sample of 482 nurse practitioners completed the Attitudes and Values Scale, the Confidence in Skills Scale, and a demographic survey. Findings indicate that nurse practitioners are very confident about their practice skills and knowledge and have a very strong nursing orientation. There is a direct positive correlation between level of confidence and degree of nursing orientation. Nurses in the sample also rated themselves as more confident about hands-on skills than indirect role components such as utilization of research, change theory, and evaluation of practice outcomes. The discussion interweaves this study's findings with role theory and offers a comparison and contrast to the existing body of knowledge. PMID:8203140

Commercially available adhesives have been evaluated for crystal mounting when undertaking complex macromolecular crystallography experiments. Here, their use as tools for advanced sample mounting and cryoprotection is assessed and their suitability for room-temperature data-collection and humidity-controlled studies is investigated. The hydration state of macromolecular crystals often affects their overall order and, ultimately, the quality of the X-ray diffraction pattern that they produce. Post-crystallization techniques that alter the solvent content of a crystal may induce rearrangement within the three-dimensional array making up the crystal, possibly resulting in more ordered packing. The hydration state of a crystal can be manipulated by exposing it to a stream of air at controlled relative humidity in which the crystal can equilibrate. This approach provides a way of exploring crystal hydration space to assess the diffraction capabilities of existing crystals. A key requirement of these experiments is to expose the crystal directly to the dehydrating environment by having the minimum amount of residual mother liquor around it. This is usually achieved by placing the crystal on a flat porous support (Kapton mesh) and removing excess liquid by wicking. Here, an alternative approach is considered whereby crystals are harvested using adhesives that capture naked crystals directly from their crystallization drop, reducing the process to a one-step procedure. The impact of using adhesives to ease the harvesting of different types of crystals is presented together with their contribution to background scattering and their usefulness in dehydration experiments. It is concluded that adhesive supports represent a valuable tool for mounting macromolecular crystals to be used in humidity-controlled experiments and to improve signal-to-noise ratios in diffraction experiments, and how they can protect crystals from modifications in the sample environment is discussed.

Experimental research has become complex and thus a challenge to science education. Only very few students can typically be trained on advanced scientific equipment. It is therefore important to find new tools that allow all students to acquire laboratory skills individually and independent of where they are located. In a design-based research process we have investigated the feasibility of using a virtual laboratory as a photo-realistic and scientifically valid representation of advanced scientific infrastructure to teach modern experimental science, here, molecular quantum optics. We found a concept based on three educational principles that allows undergraduate students to become acquainted with procedures and concepts of a modern research field. We find a significant increase in student understanding using our Simulated Interactive Research Experiment (SiReX), by evaluating the learning outcomes with semi-structured interviews in a pre/post design. This suggests that this concept of an educational tool can be generalized to disseminate findings in other fields.

Decision models are essential tools for coastal groundwater management (CGM). A combined simulation-optimization framework is employed to develop these models. One of the main barriers in the widespread application of these models for real-world cases is their large computational burden. Recent advances in efficient computational approaches and robust optimization methods can crack this barrier. This study surveys the scientific basis of CGM to provide an overview on this subject and reviews the-state-of-the-art to clarify recent developments and to outline ideas for improving the computational performance. Key details are presented on the performance and choice of possible robust tools such as efficient evolutionary algorithms (EAs), surrogate models, and parallel processing techniques. Then, the potential challenges remaining in this context are scrutinized, demonstrating open fields for further research, which include issues related to advances in simulating and optimizing phases such as introducing new robust algorithms and considering multi-objective purposes, implementing novel and high-performance tools, considering global concerns (e.g. climate change impacts), enhancing the existing models to fit the real world, and taking into account the complexities of real-world applications (e.g. uncertainties in the modeling parameters, and data acquisition). Finally, the outcomes of the systematic review are applied to solve a real-world CGM problem in Iran, to quantitatively examine the performance of combined implementation of some of the suggested tools. It is revealed that the required computational time is considerably reduced by as much as three orders of magnitude when correct combinations of robust EAs, surrogate model, and parallelization technique are utilized.

In 1994 the first high-energy particle physics experiment for the Space Station, the Alpha Magnetic Spectrometer (AMS), was selected by NASA's Administrator as a joint collaboration with the U.S. Department of Energy (DOE). The AMS program was chartered to place a magnetic spectrometer in Earth orbit and search for cosmic antimatter. A natural consequence of this decision was that NASA would begin to explore cost-effective ways through which the design and implementation of AMS might benefit other promising payload experiments which were evolving from the Office of Space Science. The first such experiment to come forward was ACCESS in 1996. It was proposed as a new mission concept in space physics to place a cosmic-ray experiment of weight, volume, and geometry similar to the AMS on the ISS, and replace the latter as its successor when the AMS is returned to Earth. This was to be an extension of NASA's sub-orbital balloon program, with balloon payloads serving as the precursor flights and heritage for ACCESS. The balloon programs have always been a cost-effective NASA resource since the particle physics instrumentation for balloon and space applications are directly related. The next step was to expand the process, pooling together expertise from various NASA centers and universities while opening up definition of the ACCESS science goals to the international community through the standard practice of peer-review. This process is still on-going and the Accommodation Study presented here will discuss the baseline definition of ACCESS as we understand it today. Further detail on the history, scope, and background of the study is provided in Appendix A.

This paper reports on a funded project that explored the perceptions and experiences of mentors regarding student nurse support in practice. The study employed a mixed-method approach, using questionnaires and focus groups with mentors from one acute Trust and one community Trust. The findings highlighted the multifaceted nature of student learning in practice, with mentors reporting that clinical skills, adjustment to the placement and integrating into the team were the aspects students needed most support with. Mentors were aware of their roles and responsibilities in supporting students and recognized the importance of their own personal attributes. The participants reported a number of challenges, particularly time, competing demands and paperwork, and suggested that a team approach and support groups could help to overcome these. The support for students provided by peers and health-care assistants was recognized, as was the need to ensure that students are prepared to take responsibility for their learning. PMID:25157940

In 2009, the International Soil Moisture Network (ISMN; http:www.ipf.tuwien.ac.at) was initiated as a platform to support calibration and validation of soil moisture products from remote sensing and land surface models, and to advance studies on the behavior of soil moisture over space and time. This international initiative is fruit of continuing coordinative efforts of the Global Energy and Water Cycle Experiment (GEWEX) in cooperation with the Group of Earth Observation (GEO) and the Committee on Earth Observation Satellites (CEOS). The decisive financial incentive was given by the European Space Agency (ESA) who considered the establishment of the network critical for optimizing the soil moisture products from the Soil Moisture and Ocean Salinity (SMOS) mission. The ISMN collects and harmonizes ground-based soil moisture data sets from a large variety of individually operating networks and makes them available through a centralized data portal. Meanwhile, almost 6000 soil moisture data sets from over 1300 sites, distributed among 34 networks worldwide, are contained in the database. The steadily increasing number of organizations voluntarily contributing to the ISMN, and the rapidly increasing number of studies based on the network show that the portal has been successful in reaching its primary goal to promote easy data accessibility to a wide variety of users. Recently, several updates of the system were performed to keep up with the increasing data amount and traffic, and to meet the requirements of many advanced users. Many datasets from operational networks (e.g., SCAN, the US Climate Reference Network, COSMOS, and ARM) are now assimilated and processed in the ISMN on a fully automated basis in near-real time. In addition, a new enhanced quality control system is currently being implemented. This presentation gives an overview of these recent developments, presents some examples of important scientific results based on the ISMN, and sketches an outlook for
Full Text Available Abstract Background Image analysis of microarrays and, in particular, spot quantification and spot quality control, is one of the most important steps in statistical analysis of microarray data. Recent methods of spot quality control are still in early age of development, often leading to underestimation of true positive microarray features and, consequently, to loss of important biological information. Therefore, improving and standardizing the statistical approaches of spot quality control are essential to facilitate the overall analysis of microarray data and subsequent extraction of biological information. Findings We evaluated the performance of two image analysis packages MAIA and GenePix (GP using two complementary experimental approaches with a focus on the statistical analysis of spot quality factors. First, we developed control microarrays with a priori known fluorescence ratios to verify the accuracy and precision of the ratio estimation of signal intensities. Next, we developed advanced semi-automatic protocols of spot quality evaluation in MAIA and GP and compared their performance with available facilities of spot quantitative filtering in GP. We evaluated these algorithms for standardised spot quality analysis in a whole-genome microarray experiment assessing well-characterised transcriptional modifications induced by the transcription regulator SNAI1. Using a set of RT-PCR or qRT-PCR validated microarray data, we found that the semi-automatic protocol of spot quality control we developed with MAIA allowed recovering approximately 13% more spots and 38% more differentially expressed genes (at FDR = 5% than GP with default spot filtering conditions. Conclusion Careful control of spot quality characteristics with advanced spot quality evaluation can significantly increase the amount of confident and accurate data resulting in more meaningful biological conclusions.
Full Text Available Locally advanced breast cancer (LABC accounts for a sizeable number (30-60% of breast cancer cases and is a common clinical scenario in developing countries. The treatment of LABC has evolved from single modality treatment, consisting of radical mutilating surgery or higher doses of radiotherapy in inoperable disease to multimodality management, which along with the above two included systemic therapy. Neoadjuvant chemotherapy (NACT has made a tremendous impact on the management of LABC. NACT was initiated to institute systemic therapy upfront at the earliest in this group of patients with a high risk of micrometastasis burden. While NACT did not yield a survival advantage, it has however made breast conservation possible in selected group of cases. Large number of studies and many randomised trials have been done in women with LABC in order to improve the therapeutic decisions and also the local control and survival. With this background we have reviewed various treatment options in patients with LABC which should possibly help in guiding the clinicians for optimal management of LABC.

Full Text Available The authors review five major findings in reading comprehension and their implications for educational practice. First, research suggests that comprehension skills are separable from decodingprocesses and important at early ages, suggesting that comprehension skills should be targeted early, even before the child learns to read. Second, there is an important distinction between readingprocesses and products, as well as their causal relationship: processes lead to certain products. Hence, instructional approaches and strategies focusing on processes are needed to improve students’reading performance (i.e., product. Third, inferences are a crucial component of skilled comprehension. Hence, children need scaffolding and remediation to learn to generate inferences, even when they know little about the text topic. Fourth, comprehension depends on a complex interaction between the reader, the characteristics of the text, and the instructional task, highlighting the need for careful selection of instructional materials for individual students and specific groups of students. Finally, educators may benefit from heightened awareness of the limitations and inadequacies of standardized reading comprehension assessments, as well as the multidimensionality of comprehension to better understand their students’ particular strengths and weaknesses.

Following pioneering work 40 years ago, synchrotron beamlines dedicated to macromolecular crystallography (MX) have improved in almost every aspect as instrumentation has evolved. Beam sizes and crystal dimensions are now on the single micron scale while data can be collected from proteins with molecular weights over 10 MDa and from crystals with unit cell dimensions over 1000 Å. Furthermore it is possible to collect a complete data set in seconds, and obtain the resulting structure in minutes. The impact of MX synchrotron beamlines and their evolution is reflected in their scientific output, and MX is now the method of choice for a variety of aims from ligand binding to structure determination of membrane proteins, viruses and ribosomes, resulting in a much deeper understanding of the machinery of life. A main driving force of beamline evolution have been advances in almost every aspect of the instrumentation comprising a synchrotron beamline. In this review we aim to provide an overview of the current status of instrumentation at modern MX experiments. The most critical optical components are discussed, as are aspects of endstation design, sample delivery, visualisation and positioning, the sample environment, beam shaping, detectors and data acquisition and processing.

Pre-participation screening of athletes for underlying cardiovascular disease is recommended by the AHA/ACC. However, vigorous debate continues as to whether the ECG should be used as part of a broad-based screening program. The AHA/ACC "do not support national mandatory screening ECGs of athletes, because the logistics, manpower, financial and resource considerations make such a program inapplicable to US". In an effort to address these impediments and to increase access for communities, we explore the use of advanced practice providers (Nurse Practitioners and Physician Assistants) in providing pre-participation screening to athletes with ECG interpretation. In the current healthcare environment with limited primary care resources, advanced practice providers are an important new element in improving access to care. Pre-participation screening with ECG interpretation is currently within an advanced practice provider's scope of practice. Emerging data shows that advanced practice providers perform care that is within acceptable patient care standards, safely, and cost effectively, compared to physician counterparts. To further improve pre-participation screening, a national education and certification program on 12-lead ECG interpretation is needed. Standardized screening tools and mass screening protocols that include screening ECGs for targeted athlete populations who are at high risk for SCD are needed. These recommendations are aimed at addressing some of the barriers raised by the AHA/ACC group to pre-participation screening with ECG. PMID:25791248

In this paper we explore the theory of communities of practice in the context of a physics college course and in particular the classroom environment of an advanced laboratory. We introduce the idea of elements of a classroom community being able to provide students with the opportunity to have an accelerated trajectory towards being a more central participant of the community of practice of physicists. This opportunity is a result of structural features of the course and a primary instructional choice which result in the development of a learning community with several elements that encourage students to engage in more authentic practices of a physicist. A jump in accountable disciplinary knowledge is also explored as a motivation for enculturation into the community of practice of physicists. In the advanced laboratory what students are being assessed on as counting as physics is significantly different and so they need to assimilate in order to succeed.

Sixty percent of American high schools offer one or more Advanced Placement courses, and several thousand Advanced Placement teachers serve as Readers or graders of Advanced Placement exams each year. This study was conducted to determine the characteristics of teachers who choose to participate in Advanced Placement Environmental Science Readings and determine how these teachers view the Reading experience as a form of professional development. This study was conducted with teacher participants at the June 2004 Advanced Placement Environmental Science Reading. Sixty of the 114 teacher participants completed a survey regarding their education background, age, experience level, educational philosophy, involvement in professional development opportunities, perceptions of the professional benefits of the Reading, and the influence of the Reading experience on their pedagogical practices. Semi-structured interviews were then conducted with a subset of 18 teacher participants to determine their perceptions regarding the professional benefits of the Reading experience, its potential to serve as a professional development activity, and perceived changes in their pedagogical practices resulting from participation in the Reading process. Results indicate that APES Reading teacher participants are experienced, effective teachers from many parts of the country. These teachers participate in ongoing professional development activities, can delineate components of effective professional development, strongly believe that effective professional development occurs at the APES Reading, and report that their pedagogical practice has improved as a result of participation in the APES Reading. Considering the crucial role teachers play in the educational process, it is important to pursue this additional avenue of professional development in order to further improve APES teacher effectiveness.
Results of the Advanced Containment Experiments (ACE) Radioiodine Test Facility (RTF) program are reported. This study consisted of four intermediate-scale experiments that investigated the effects of radiation, pH, surfaces and initial iodine speciation on iodine behaviour. The tests revealed that, in high radiation fields, the long-term volatility of iodine is independent of the initial iodine speciation (CsI, I2, CH3I). This is presumably because radiolytic reactions inter-convert aqueous iodine species; I- was the predominant aqueous iodine species after an absorbed dose of about 30-40 kGy. Tests at pH 9 and 5.5 demonstrated that iodine volatility increased significantly with decreasing pH. In addition, this study demonstrated that containment surfaces can play an important role in determining iodine volatility, gas and aqueous phase iodine speciation, and surface adsorption. In summary: The ACE/RTF experiments have demonstrated the importance of several factors on iodine behaviour within containment under reactor accident conditions. One of the most important factors was radiation. Without radiation, the volatility of iodine was dependent on the initial speciation of iodine, presumably because inter-conversion of iodine species by non-radiolytic reactions is relatively slow. In contrast, in the presence of radiation, the long-term volatility of iodine was independent of initial speciation. This is attributed to aqueous phase radiolytic reactions that result in rapid inter-conversion of iodine species. Iodine volatility was shown to increase significantly with decreasing pH. However, changing the pH from acidic to alkaline conditions did not result in rapid decreases in iodine volatility. This may have been due to desorption of volatile iodine species from surfaces, in the case of stainless steel, and the influence of organics in the epoxy tests. Surfaces were shown to influence iodine volatility and speciation. Higher gas phase iodine concentrations were

Quality improvement measures are uniformly applied to all oncology providers, regardless of their roles. Little is known about differences in adherence to these measures between oncology fellows, advance practice providers (APP), and attending physicians. We investigated conformance across Quality Oncology Practice Initiative (QOPI) measures for oncology fellows, advance practice providers, and attending physicians at the Durham Veterans Affairs Medical Center (DVAMC). Using data collected from the Spring 2012 and 2013 QOPI cycles, we abstracted charts of patients and separated them based on their primary provider. Descriptive statistics and the chi-square test were calculated for each QOPI measure between fellows, advanced practice providers (APPs), and attending physicians. A total of 169 patients were reviewed. Of these, 31 patients had a fellow, 39 had an APP, and 99 had an attending as their primary oncology provider. Fellows and attending physicians performed similarly on 90 of 94 QOPI metrics. High-performing metrics included several core QOPI measures including documenting consent for chemotherapy, recommending adjuvant chemotherapy when appropriate, and prescribing serotonin antagonists when prescribing emetogenic chemotherapies. Low-performing metrics included documentation of treatment summary and taking action to address problems with emotional well-being by the second office visit. Attendings documented the plan for oral chemotherapy more often (92 vs. 63%, P=0.049). However, after the chart audit, we found that fellows actually documented the plan for oral chemotherapy 88% of the time (p=0.73). APPs and attendings performed similarly on 88 of 90 QOPI measures. The quality of oncology care tends to be similar between attendings and fellows overall; some of the significant differences do not remain significant after a second manual chart review, highlighting that the use of manual data collection for QOPI analysis is an imperfect system, and there may

The knowledge and models obtained have a common element of mortality risk indicators but these are varied in different parts of the world. The common elements of these studies and models are generally based on a series of indicators which mainly point out their probability of survival and they are named the mortality indicators. These indicators represent the basis for the calculation of the premiums quotes and for the elaboration by the insurers of premium tables. The benefit for the policyholder is to obtain insurance at a fair and competitive price and for the insurer, to maintain the experience of its portfolio in line with mortality assumptions.
Full Text Available Physicians' emotions affect both patient care and personal well-being. Surgeons appear at particularly high risk, as evidenced by the high rate of burnout and the alarming consequences in both their personal lives and professional behavior. The aim of this qualitative study is to explore the emotional experiences of surgeons and their impact on their surgical practice.27 purposively selected liver and pancreatic surgeons from 10 teaching hospitals (23 men, 4 women participated. Inclusion took place until data saturation was reached. Data were collected through individual interviews and thematically analyzed independently by 3 researchers (a psychologist, a psychiatrist, and a surgeon. 7 themes emerged from the analysis, categorized in 3 main or superordinate themes, which described surgeons' emotional experience before, during, and after surgery. Burdensome emotions are present throughout all 3 periods (and invade life outside the hospital-surgeons' own emotions, their perception of patients' emotions, and their entwinement.

A change in British health care has resulted in a broadening of roles and responsibilities beyond 'traditional boundaries' for a range of health care professionals. This has occurred because of staff shortages (particularly within the medical profession) and the recognition that many 'non-doctor' health care staff can make safe, competent and effective contributions outside their 'normal' sphere of responsibilities. In the context of advanced clinical practice, this paper will explain the current arrangements for radiographers' roles and responsibilities, their accountability and the educational provision that underpins the development of competencies at these higher clinical levels. Some advanced roles that British radiographers perform, within their current normal responsibilities, will be identified and some British legislation and professional body guidance that make role advancement possible will be outlined. The article will conclude with an indication of the educational level at which the advanced competencies are learned and assessed. (author)

Public Health Nursing 7(1), 33-39; United Kingdom Central Council for Nursing, Midwifery and Health Visiting, 1986. Project 2000: A New Preparation for Practice. UKCC, London). Such changes have major implications for pre-registration nursing education, including its practice placement element. From an educational perspective, the need for increased community nursing capacity must be balanced with adequate support for student nurses' learning needs during community-based placements. This qualitative study explored six second year student nurses' experiences of 12 week community-based practice placements and the extent to which these placements were seen to meet their perceived learning needs. The data came from contemporaneous reflective diaries, completed by participants to reflect their 'lived experience' during their practice placements (Landeen, J., Byrne, Brown, B., 1995. Exploring the lived experiences of psychiatric nursing students through self-reflective journals. Journal of Advanced Nursing 21(5), 878-885; Kok, J., Chabeli, M.M., 2002.

A concrete way of recognizing and rewarding clinical leadership, excellence in practice, and personal and professional development of the advanced practice registered nurse (APRN) is lacking in the literature and healthcare institutions in the United States. This article presents the process of developing and evaluating a professional development program designed to address this gap. The program uses APRN Professional Performance Standards, Relationship-Based Care, and the Magnet Forces as a guide and theoretical base. A key tenet of the program is the creation of a professional portfolio. Narrative reflections are included that illustrate the convergence of theories. A crosswalk supports this structure, guides portfolio development, and operationalizes the convergence of theories as they specifically relate to professional development in advanced practice. Implementation of the program has proven to be challenging and rewarding. Feedback from APRNs involved in the program supports program participation as a meaningful method to recognize excellence in advanced practice and a clear means to foster ongoing professional growth and development.

This paper describes the evolution and current status of advanced practice in medical imaging and radiation therapy in the Oceania region. To date development has been slow, largely ad hoc and based on local needs. Most advanced practice is informal or is regarded as part of the core skills of some individual practitioners. However, recently, there have been signs of change taking place, with a more coordinated and collaborative approach to role development becoming evident. In Australia, although a number of reports and papers have discussed extended clinical roles, especially for diagnostic Radiographers, no concrete action has yet taken place in either discipline. Stakeholders apparently agree that existing extended roles should be formalised, however, and that continuing education must underpin future role extension initiatives. A three-level professional structure, including an advanced practitioner level, has been accepted by the New Zealand Institute of Medical Radiation Technology (NZIMRT), with the support of the District Health Boards of New Zealand (DHBNZ). Implementation is expected to begin before the end of 2008. Meanwhile, recognition of the serious lack of Radiologists in Western Pacific Island Nations led to the training of some Radiographers in radiological interpretation of images between 2004 and 2006. The aim was to up-skill the Radiographers so that they could more reliably flag abnormalities to doctors, a model that may be applicable elsewhere. It is argued that future practice models must include advanced practice roles in order to safely meet the growing demand for medical radiation services. Local factors, such as the structure of the health care system and the depth of engagement of the key stakeholders in planning and implementation, however, are expected to influence the evolution of new clinical practice models in the region

Repetition is the most commonly used practice strategy by musicians. Although blocks of repetition continue to be suggested in the pedagogical literature, work in the field of cognitive psychology suggests that repeated events receive less processing, thereby reducing the potential for long-term learning. Motor skill learning and sport psychology research offer an alternative. Instead of using a blocked practice schedule, with practice completed on one task before moving on to the next task, an interleaved schedule can be used, in which practice is frequently alternated between tasks. This frequent alternation involves more effortful processing, resulting in increased long-term learning. The finding that practicing in an interleaved schedule leads to better retention than practicing in a blocked schedule has been labeled the “contextual interference effect.” While the effect has been observed across a wide variety of fields, few studies have researched this phenomenon in a music-learning context, despite the broad potential for application to music practice. This study compared the effects of blocked and interleaved practice schedules on advanced clarinet performance in an ecologically valid context. Ten clarinetists were given one concerto exposition and one technical excerpt to practice in a blocked schedule (12 min per piece) and a second concerto exposition and technical excerpt to practice in an interleaved schedule (3 min per piece, alternating until a total of 12 min of practice were completed on each piece). Participants sight-read the four pieces prior to practice and performed them at the end of practice and again one day later. The sight-reading and two performance run-throughs of each piece were recorded and given to three professional clarinetists to rate using a percentage scale. Overall, whenever there was a ratings difference between the conditions, pieces practiced in the interleaved schedule were rated better than those in the blocked schedule

The application of modern molecular tests such as next-generation sequencing (NGS) to human malignancies has led to better understanding of tumor biology and the design of targeted molecular therapies. In the research setting, important genomic alterations in tumors have been discovered with potential therapeutic implications but data regarding the impact of this technology in a real world oncology practice is limited. As a result, we decided to review the results of NGS in 144 advanced-stage cancer patients referred to the oncology practices of Lifespan-affiliated centers in Rhode Island. Most cancers revealed genomic alterations in genes commonly mutated in cancer. However, several unexpected genomic alterations were discovered in certain cancers with potential therapeutic intervention. Most cancers contained "actionable" genomic alterations despite being of advanced stage. Our experience demonstrates that application of NGS in the clinical setting contributes both to increasing the therapeutic armamentarium as well as our understanding of tumor biology. PMID:26422540

Health Impact Assessment (HIA) is recognized as a useful tool that can identify potential health impacts resulting from projects or policy initiatives. Although HIA has become an established practice in some countries, it is not yet an established practice in Canada. In order to enable broader support for HIA, this study provides a comprehensive review and analysis of the peer-reviewed and gray literature on the state of HIA practice. The results of this review revealed that, although there is an abundance of publications relating to HIA, there remains a lack of transparent, consistent and reproducible approaches and methods throughout the process. Findings indicate a need for further research and development on a number of fronts, including: 1) the nature of HIA triggers; 2) consistent scoping and stakeholder engagement approaches; 3) use of evidence and transparency of decision-making; 4) reproducibility of assessment methods; 5) monitoring and evaluation protocols; and, 6) integration within existing regulatory frameworks. Addressing these issues will aid in advancing the more widespread use of HIA in Canada. - Highlights: • Reviewed current state of practice in the field of HIA • Identified key obstacles and opportunities for HIA advancement • Major issues include lack of consistent approach and methodology. • No national regulatory driver hinders opportunity for widespread use of HIA. • Identified research opportunities vital to developing HIA practice in Canada.

Full Text Available Well-organised medical records are the prerequisite for achieving a high level of performance in primary healthcare settings. Recording balanced structured and coded data as well as free text can improve both quality and organisation of work in the office. It provides a more substantiated support of financial transactions and accountancy, allows better communication with other facilities and institutions, and is a source of valuable scientific research material. This article is the result of an individual experience gained in general practice use of various programs/ systems employed within the family medicine frame, and the frame of evaluation of available and commonly- exploited program solutions. The use of various programs allows for systematic adjustments as to the increasingly complex requirements imposed on electronic medical records (EMRs. The experience of a general practitioner, presented in this paper, confirms the assumption that an adequate program to be employed with EMRs should be developed, provided that family medicine practitioners, that is, the final users, have been involved in each and every stage of its development, adjustment, implementation and evaluation.

As nurses and patient populations increasingly reflect the changing demographics of the United States, it will be necessary for nurses to address the critical issues surrounding a multicultural society. Nurses have been relatively quiet on the topic of ethnocentric and racist behavior. If advanced practice nurses are to be successful in assisting nurses and organizations to embrace cultural diversity, understanding ethnocentric and racist behaviors is key to developing strategies to facilitate the provision of culturally competent care.

Gaps in complex oncology care coordination between inpatient and outpatient settings can result in treatment and monitoring delays and omissions, which can negatively affect patient outcomes. Gaps also exist for patients facing complex treatment modalities and collaborations between multiple care teams working at geographically distant sites. A pilot advanced practice nurse care coordinator (APNCC) role to coordinate these complex care transitions and implement processes for safer and more efficient care has shown promise. . PMID:27206289

Advanced practice nursing expertise has been acknowledged worldwide as one response to the challenges arising from changes in society and health care. The roots of advanced practice nursing education are at the University of Colorado where the first known programme started in 1965. In many countries advanced practice nurses (APNs) have taken responsibility for routine patient care formerly carried out by physicians in order to reduce their workload. However, more and more, APNs have taken responsibility for new service areas and quality programmes not previously provided. Chronic disease management is one of these new service areas because long-term diseases are increasingly challenging service systems globally. This article is based on an international APN partnership. The aim of the article is to describe how the partnership will design a 15 ECTS credit course on Enduring Health Need Management as a cross-cultural collaborative endeavour. The adaptation of an inquiry based learning framework will be described drawing on four main principles of the theory: authentic learning communities; student encouragement in analysing gradually more complicated problems; networking in knowledge creation and; student engagement and activity. The cross-cultural online course aims to increase APNs' intercultural competence as well as their global and international work orientation. PMID:21839552

During the last five years, a new approach to the design and fabrication of extruded aluminum vacuum chambers for insertion devices was developed at the Advanced Photon Source (APS). With this approach, three different versions of the vacuum chamber, with vertical apertures of 12 mm, 8 mm, and 5 mm, were manufactured and tested. Twenty chambers were installed into the APS vacuum system. All have operated with beam, and 16 have been coupled with insertion devices. Two different vacuum chambers with vertical apertures of 16 mm and 11 mm were developed for the BESSY-II storage ring and 3 of 16 mm chambers were manufactured

The improvement of prediction models is needed to enhance the safety analysis capability through experimental database of local phenomena. To improve the two-phase interfacial area transport model, the various experiments were carried out with local two-phase interfacial structure test facilities. 2 Χ 2 and 6 Χ 6 rod bundle test facilities were used for the experiment on the droplet behavior. The experiments on the droplet behavior inside a heated rod bundle geometry. The experiments used GIRLS and JICO and CFD analysis were carried out to comprehend the local condensation of steam jet, turbulent jet induced by condensation and the thermal mixing in a pool. In order to develop a model for key phenomena of newly adapted safety system, experiments for boiling inside a pool and condensation in horizontal channel have been performed. An experimental database of the CHF (Critical Heat Flux) and PDO (Post-dryout) was constructed. The mechanism of the heat transfer enhancement by surface modifications in nano-fluid was investigated in boiling mode and rapid quenching mode. The special measurement techniques were developed. They are Double-sensor optical void probe, Optic Rod, PIV technique and UBIM system

In 1992, an Engineering Test Satellite 6 is scheduled to be launched by an H-2 rocket. The missions of ETS-6 are to establish basic technologies of inter-satellite communications using S-band, millimeter waves and optical beams and of fixed and mobile satellite communications using multibeam antenna on board the satellite. A plan of the experiments is introduced.
We present the initial results of an experimental study of a beam timing monitor based on an optoelectronic technique. This technique uses the electrical signal from a beam position monitor to modulate the amplitude of a train of laser pulses, converting timing jitter into an amplitude jitter. This modulation is then measured with a photodetector and sampled by a fast ADC. This approach has already demonstrated sub-100fs resolution and promises even better results. Additionally, we are planning to use the technique as a way to extract the maximum possible bandwidth from a BPM, avoiding the dispersion typical of long RF cables. We show our initial results using signals from the Advanced Light Source storage ring

For over 30 years, the NASA Airborne Science Program has provided airborne platforms for space bound instrument development, for calibrating new and existing satellite systems, and for making in situ and remote sensing measurements that can only be made from aircraft. New technologies have expanded the capabilities of aircraft that are operated for these missions. Over the last several years a new technology investment portfolio has yielded improvements that produce better measurements for the airborne science communities. These new technologies include unmanned vehicles, precision trajectory control and advanced telecommunications capabilities. We will discuss some of the benefits of these new technologies and systems which aim to provide users with more precision, lower operational costs, quicker access to data, and better management of multi aircraft and multi sensor campaigns.
The characteristics and requirements of the seismic instrument for mapping the internal structure of the planet Mars are briefly described. The types of signals expected to exist are microseismic background generated by wind and pressure variations and thermal effects, disturbances of or in the landed vehicle, signals caused by faulting and volcanic activity, and signals due to meteoritic impacts. The advanced instrument package should include a short-period vertical component system, a long-period or wide-band 3-component system, a high frequency vertical component system, and a system for detection and rejection of lander noises. The Viking '75, Surveyor, and Apollo systems are briefly described as potential instruments to be considered for modification. Data processing and control systems are also summarized.
The development of an accelerated version of the advanced CATHARe-1 thermal hydraulics code designed for EDF training simulators (CATHARE-SIMU) was successfully completed as early as 1991. Its successful integration as the principal model of the SIPA Post-Accident Simulator meant that its use could be extended to full-scale simulators as part of the renovation of the stock of existing simulators. In order to further extend the field of application to accidents occurring in shutdown states requiring action and to catch up with developments in respect of the CATHARE code, EDF initiated the SCAR Project designed to adapt CATHARE-2 to simulator requirements (acceleration, parallelization of the computation and extension of the simulation range). In other respects, the installation of SIPA on workstations means that the authors can envisage the application of this remarkable training facility to the understanding of thermal hydraulics accident phenomena

Tube degradation in certain recirculating nuclear steam generators has provided a market for steam generator replacement. Prior to this need, B and W supplied over 200 steam generators for CANDU nuclear plants. With this experience, and implementing extensive research and development improvements in material selection, design enhancements, and new manufacturing and analytical methods, B and W has supplied or secured orders for the replacement of 26 steam generators. Along with plans for new replacement orders, B and W will continue to supply steam generators for future CANDU plants. This paper will review the progression of B and W's CANDU experience to meet the replacement steam generator market, and examine the continuous improvements required for today's increasingly demanding nuclear specifications.

As the field of nuclear resonant scattering using synchrotron radiation matures, we see a shift from experiments designed to verify theoretical predictions towards those designed to use the phenomenon to elucidate the behavior of a sample. In parallel with this trend towards applications, we have seen further instrumental developments that extend the range of possible applications. This paper will review the recent work in this field with an emphasis on new sources, new isotopes, and new instrumentation. copyright 1996 American Institute of Physics

Motorcyclists are over-represented in collision statistics. While many collisions may be the direct fault of another road user, a considerable number of fatalities and injuries are due to the actions of the rider. While increased riding experience may improve skills, advanced training courses may be required to evoke the safest riding behaviours. The current research assessed the impact of experience and advanced training on rider behaviour using a motorcycle simulator. Novice riders, experienced riders and riders with advanced training traversed a virtual world through varying speed limits and roadways of different curvature. Speed and lane position were monitored. In a comparison of 60 mph and 40 mph zones, advanced riders rode more slowly in the 40 mph zones, and had greater variation in lane position than the other two groups. In the 60 mph zones, both advanced and experienced riders had greater lane variation than novices. Across the whole ride, novices tended to position themselves closer to the kerb. In a second analysis across four classifications of curvature (straight, slight, medium, tight) advanced and experienced riders varied their lateral position more so than novices, though advanced riders had greater variation in lane position than even experienced riders in some conditions. The results suggest that experience and advanced training lead to changes in behaviour compared to novice riders which can be interpreted as having a potentially positive impact on road safety.

The United States Department of Energy’s Advanced Gas Reactor (AGR) Fuel Development and Qualification Program will be irradiating eight separate tri-isotopic (TRISO) particle fuel (in compact form) experiments in the Advanced Test Reactor (ATR) located at the Idaho National Laboratory (INL). These irradiations and fuel development are being accomplished to support development of the next generation reactors in the United States. The ATR has a long history of irradiation testing in support of reactor development and the INL has been designated as the United States Department of Energy’s lead laboratory for nuclear energy development. These AGR fuel experiments will be irradiated over the next ten years to demonstrate and qualify new particle fuel for use in high temperature gas reactors. The experiments, which will each consist of six separate capsules, will be irradiated in an inert sweep gas atmosphere with individual on-line temperature monitoring and control for each capsule. The swept gas will also have on-line fission product monitoring to track performance of the fuel in each individual capsule during irradiation. The design of the first experiment (designated AGR-1) was completed in 2005, and the fabrication and assembly of the test train as well as the support systems and fission product monitoring system that monitor and control the experiment during irradiation were completed in September 2006. The experiment was inserted in the ATR in December 2006, and is serving as a shakedown test of the multi-capsule experiment design that will be used in the subsequent irradiations as well as a test of the early variants of the fuel produced under this program. The experiment test train as well as the monitoring, control, and data collection systems are discussed and the status of the experiment is provided.

The 'Atoms for Peace' mission initiated in the mid-1950s paved the way for the development and deployment of nuclear fission reactors as a source of heat energy for electricity generation in nuclear power reactors and as a source of neutrons in non-power reactors for research, materials irradiation, and testing and production of radioisotopes. The fuels for nuclear reactors are manufactured from natural uranium (∼99.3% 238U + ∼0.7% 235U) and natural thorium (∼100% 232Th) resources. Currently, most power and research reactors use 235U, the only fissile isotope found in nature, as fuel. The fertile isotopes 238U and 232Th are transmuted in the reactor to human-made 239Pu and 233U fissile isotopes, respectively. Likewise, minor actinides (MA) (Np, Am and Cm) and other plutonium isotopes are also formed by a series of neutron capture reactions with 238U and 235U. Long term sustainability of nuclear power will depend to a great extent on the efficient, safe and secure utilization of fissile and fertile materials. Light water reactors (LWRs) account for more than 82% of the operating reactors, followed by pressurized heavy water reactors (PHWRs), which constitute ∼10% of reactors. LWRs will continue to dominate the nuclear power market for several decades, as long as economically viable natural uranium resources are available. Currently, the plutonium obtained from spent nuclear fuel is subjected to mono recycling in LWRs as uranium-plutonium mixed oxide (MOX), containing up to 12% PuO2, in a very limited way. The reprocessed uranium (RepU) is also re-enriched and recycled in LWRs in a few countries. Unfortunately, the utilization of natural uranium resources in thermal neutron reactors is 2 and MOX fuel technology has matured during the past five decades. These fuels are now being manufactured, used and reprocessed on an industrial scale. Mixed uranium- plutonium monocarbide (MC), mononitride (MN) and U-Pu-Zr alloys are recognized as advanced fuels for sodium

This study tackles the puzzle of why increasing entrepreneurial experience does not always lead to improved financial performance of new ventures. We propose an alternate framework demonstrating how experience translates into expertise by arguing that the positive experience-performance relationship only appears to expert entrepreneurs, while novice entrepreneurs may actually perform increasingly worse because of their inability to generalize their experiential knowledge accurately into new v...
Full Text Available The article presents the results of three burial experiments, carriedout in 2005, the aim of which was to attempt to understand what exactly happens to a physical body after death in different environments. The experiments were simulations of an open air burial, a stone cist burial and a cremation, for which the dead bodies of a calf and pigs were used. Next to technical documentation, the emotions and impressions of the experiment participants during theobservations of body decomposition and the cremation process were recorded. The authors suggest that a cognitive approach to burial experiments could offer us an alternative view to understanding rituals and interpreting prehistoric burials.

The origin of this accident was the repair of a valve when about 14 t of sodium was spilled in the plant room over a period of 1/2 hour. The event has been reported (IAEA/IWGFR meeting in 1988) and this presentation gives a short review of important feedback. The Almeria accident was one of the reasons that from that time spray fires had to be taken into account in the safety analyses of nuclear power plants. Due to the fact that spray fire codes were not available in a sufficiently validated state, safety analyses were provisionally based on the feedback from sodium fire tests and also from the Almeria accident itself. The behaviour of spray fires showed that severe destruction, up to melting of metallic structures may occur, but even with a large spray fire is limited roughly within the spray fire zone itself. This could be subsequently be predicted by codes like NABRAND in Germany and FEUMIX in France. Almeria accident has accelerated R and D and code development with respect to spray fires. As example for a code validation some figures are given for the NABRAND code. Another large sodium fire accident happened in 1992 in the test facility at Bensberg in Germany (ILONA). This accident occurred during preheating of a sodium filled vessel which was provisionally installed in the basement of the ILONA test facility at Bensberg. Due to failure of a pressure relief valve the pressure in the vessel increased. As a consequence the plug in a dip tube for draining the vessel failed and about 4,5 t of sodium leaked slowly from the vessel. The plant room was not cladded with steel liners or collecting pans (it was not designed for permanent sodium plant operation). So leaking sodium came directly in

Does authentic assessment or the perception of it affect how students study and learn? Does practical experience affect how assessment authenticity is perceived? And does practical experience influence how an authentic assessment affects student learning? Mixed methods design yielded insight into th

We use the theory of communities of practice and the concept of accountable disciplinary knowledge to describe how a learning community develops in the context of an upper-division physics laboratory course. The change in accountable disciplinary knowledge motivates students' enculturation into a community of practice. The enculturation process is facilitated by four specific structural features of the course and supported by a primary instructional choice. The four structural features are "paucity of instructor time," "all in a room together," "long and difficult experiments," and "same experiments at different times." The instructional choice is the encouragement of the sharing and development of knowledge and understanding by the instructor. The combination of the instructional choice and structural features promotes the development of the learning community in which students engage in authentic practices of a physicist. This results in a classroom community that can provide students with the opportunity to have an accelerated trajectory towards being a more central participant of the community of a practice of physicists. We support our claims with video-based observations of laboratory classroom interactions and individual, semistructured interviews with students about their laboratory experiences and physics identity.
