    Postactivation potentiation (PAP) is known to enhance force production. Maximal isometric strength assessment protocols usually consist of two or more maximal voluntary isometric contractions (MVCs). The objective of this study was to determine if PAP would influence isometric strength assessment. Healthy male volunteers (n = 23) performed two five-second MVCs separated by a 180-seconds interval. Changes in isometric peak torque (IPT), time to achieve it (tPTI), contractile impulse (CI), root mean square of the electromyographic signal during PTI (RMS), and rate of torque development (RTD), in different intervals, were measured. Significant increases in IPT (240.6 ± 55.7 N·m versus 248.9 ± 55.1 N·m), RTD (746 ± 152 N·m·s(-1) versus 727 ± 158 N·m·s(-1)), and RMS (59.1 ± 12.2% RMSMAX  versus 54.8 ± 9.4% RMSMAX) were found on the second MVC. tPTI decreased significantly on the second MVC (2373 ± 1200 ms versus 2784 ± 1226 ms). We conclude that a first MVC leads to PAP that elicits significant enhancements in strength-related variables of a second MVC performed 180 seconds later. If disconsidered, this phenomenon might bias maximal isometric strength assessment, overestimating some of these variables.

    1991-04-01

    The US Decade of the Brain offers scientists throughout the Federal Government a unique opportunity to advance and apply scientific knowledge about the brain and nervous system. During the next 10 years, scientists hope to maximize human potential through studies of human behavior, senses and communication, learning and memory, genetic/chemical alterations, and environmental interactions. Progress in these areas should lead to reductions in mortality from brain and nervous system disorders and to improvements in the quality of life. This report identifies nine research areas that could form the basis of an integrated program in the brain and behavioral sciences. A chart summarizing the Federal activities in these nine areas may be found at the back of the report. In addition, three areas that span the nine research areas -- basic research, technology and international activities -- are considered.

    The effective implementation and use of JIT manufacturing practices depends largely on the education, training, and commitment of all levels of management to a fundamental quality-first policy. Management must transfer and demonstrate that commitment to every level and extension of the manufacturing endeavor. As a company establishes and reaches toward that goal, the move to JIT manufacturing practices becomes rational and justifiable. Failing to establish and commit to a quality directive greatly diminishes the potential benefits of JIT. If all levels of manufacturing participate in the JIT planning, implementing, and maintenance procedure, the realization of positive change and improvement drives the process. Total participation makes the task of JIT implementation not only possible, but practical. Enhanced mutual respect for all concerned is a likely consequence, advancing the productive environment.

  7. High level waste at Hanford: Potential for waste loading maximization

    Hrma, P.R.; Bailey, A.W.

    1995-09-01

    The loading of Hanford nuclear waste in borosilicate glass is limited by phase-related phenomena, such as crystallization or formation of immiscible liquids, and by breakdown of the glass structure because of an excessive concentration of modifiers. The phase-related phenomena cause both processing and product quality problems. The deterioration of product durability determines the ultimate waste loading limit if all processing problems are resolved. Concrete examples and mass-balance based calculations show that a substantial potential exists for increasing waste loading of high-level wastes that contain a large fraction of refractory components

    Khansa, Ibrahim; Janis, Jeffrey E

    2015-11-01

    Modern plastic surgery resident education demands the acquisition of an ever-increasing fund of knowledge and familiarity with more surgical techniques than ever before. This all must take place within the context and boundaries of Accreditation Council for Graduate Medical Education-mandated restrictions on work hours as well as balance of education and service. Technological resources have been developed and can be used to complement the skills that residents acquire while performing their day-to-day activities such as taking care of patients, reading textbooks and journal articles, and assisting or performing surgical procedures. Those complementary resources provide the benefits of portability and accessibility, and can thus be conveniently incorporated into the hectic daily life of a resident. This article presents a summary of the most commonly used currently available advanced technologies in plastic surgery resident education, and suggestions for integration of those technologies into a curriculum.

    2016-01-01

    Educational videos have become an important part of higher education, providing an important content-delivery tool in many flipped, blended, and online classes. Effective use of video as an educational tool is enhanced when instructors consider three elements: how to manage cognitive load of the video; how to maximize student engagement with the video; and how to promote active learning from the video. This essay reviews literature relevant to each of these principles and suggests practical ways instructors can use these principles when using video as an educational tool. PMID:27789532

    2017-04-01

    Full Text Available Teaching English for non English Department students will be quite a challenge as the students have various background and interest. Handling those students in a big number in a class that requires them to speak is another impending challenge. This is an action research on role-play in English classroom for Information Technology students. This study tries to see whether recorded-role play could maximize students‘ potential in speaking. This study involved 30 students taking English course in Information Technology Faculty. The students were given a situation in which they had to act the role play. They drafted the role -play before they recorded it. The result shows that students felt less tense in acting the role. They also got more time to practice their pronunciation before recording. It even gave students who felt reluctant and shy in the class to actively participate. In addition, students could play around with the supporting background sound to show their creativity. Surprisingly, most students do their best to show their effort in their speaking as the end-product would be played in the classroom, even the most quiet students performed really well. Finally, this recorded-role play proved to be an effective way to maximize students‘ potential in speaking.

    Barriers to seamless service delivery between workforce development and mental health systems of care have kept both entities from maximizing their potential in regards to employment for job seekers with mental illness who are capable of work and seeking employment. Using a multiple case study design, this study examined the nature of collaboration between workforce development and mental health systems to understand the policies and practices in place to assist individuals with mental illness to find and keep work. The paper presents innovative strategies that involved staff from both workforce development and mental health agencies. Findings from this research identified the following collaborative strategies: (a) the creation of liaison positions and collaborative teams; (b) staff training on mental health and workforce issues; and (c) multi-level involvement of individuals with mental illness. Implications for workforce professionals are offered as a way to stimulate implementation of such strategies.

  17. Action potentials in retinal ganglion cells are initiated at the site of maximal curvature of the extracellular potential.

    2014-06-01

    The initiation of an action potential by extracellular stimulation occurs after local depolarization of the neuronal membrane above threshold. Although the technique shows remarkable clinical success, the site of action and the relevant stimulation parameters are not completely understood. Here we identify the site of action potential initiation in rabbit retinal ganglion cells (RGCs) interfaced to an array of extracellular capacitive stimulation electrodes. We determine which feature of the extracellular potential governs action potential initiation by simultaneous stimulation and recording RGCs interfaced in epiretinal configuration. Stimulation electrodes were combined to areas of different size and were presented at different positions with respect to the RGC. Based on stimulation by electrodes beneath the RGC soma and simultaneous sub-millisecond latency measurement we infer axonal initiation at the site of maximal curvature of the extracellular potential. Stimulation by electrodes at different positions along the axon reveals a nearly constant threshold current density except for a narrow region close to the cell soma. These findings are explained by the concept of the activating function modified to consider a region of lower excitability close to the cell soma. We present a framework how to estimate the site of action potential initiation and the stimulus required to cross threshold in neurons tightly interfaced to capacitive stimulation electrodes. Our results underscore the necessity of rigorous electrical characterization of the stimulation electrodes and of the interfaced neural tissue.

    We investigate the dual superconductor hypothesis in finite-temperature SU(2) lattice gluodynamics in the Spatial Maximal Abelian gauge. This gauge is more physical than the ordinary Maximal Abelian gauge due to absence of non-localities in temporal direction. We shown numerically that in the Spatial Maximal Abelian gauge the probability distribution of the abelian monopole field is consistent with the dual superconductor mechanism of confinement [ru

    1987-01-01

    The purpose of this study was to determine whether performance of a single maximal bout of exercise during weightlessness within hours of return to earth would enhance recovery of aerobic fitness and physical work capacities under a 1G environment. Ten healthy men were subjected to a 10-d bedrest period in the 6-deg headdown position. A graded maximal supine cycle ergometer test was performed before and at the end of bedrest to simulate exercise during weightlessness. Following 3 h of resumption of the upright posture, a second maximal exercise test was performed on a treadmill to measure work capacity under conditions of 1G. Compared to before bedrest, peak oxygen consumption, V(O2), decreased by 8.7 percent and peak heart rate (HR) increased by 5.6 percent in the supine cycle test at the end of bedrest. However, there were no significant changes in peak V(O2) and peak HR in the upright treadmill test following bedrest. These data suggest that one bout of maximal leg exercise prior to return from 10 d of weightlessness may be adequate to restore preflight aerobic fitness and physical work capacity.

    Rigorous usability testing of e-learn-ing resources is an important prerequisite to their wide-spread use among clinicians. This study demonstrates the application of an evidence-based approach to usability testing of two stroke-related e-learning resources (StrokEngine). 14 stroke rehabilitation clinicians (occupational therapists and physiotherapists) from Ontario, Canada participated in a 1.5 h in-person testing session. Clinicians navigated StrokEngine in search of information to answer questions on stroke assessment/intervention. Their search patterns were observed and clinicians provided verbal/written feedback about StrokEngine. Content analysis was used to generate themes and categorize them under two broad categories: facilitators and barriers to use. Five key facilitators and three key barriers to Strok-Engine use were identified and related to screen format, layout/organization, ease of navigation, quality of content, likelihood of using StrokEngine in the future, and system dysfunctions. All 14 clinicians were very or extremely satisfied with the layout/organization, quality and clinical relevance of the content, stating that they were likely to use StrokEngine in the future. All identified barriers from this study were addressed with website modifications in order to maximize the usability and navigability of StrokEngine. This rigorous methodology for usability testing can be applied during the design process of any e-learning resource.

    This study surveyed the technical potential for efficiency improvements in 150 categories of appliances and equipment representing 33 quads of primary energy use across the US economy in 2010 and (1) documented efficient product designs, (2) identified the most promising cross-cutting strategies, and (3) ranked national energy savings potential by end use. Savings were estimated using a method modeled after US Department of Energy priority-setting reports - simplified versions of the full technical and economic analyses performed for rulemakings. This study demonstrates that large savings are possible by replacing products at the end-of-life with ultra-efficient models that use existing technology. Replacing the 50 top energy-saving end-uses (constituting 30 quads of primary energy consumption in 2010) with today's best-on-market equivalents would save {approx}200 quads of US primary energy over 30 years (25% of consumption anticipated there from). For the 29 products for maximum feasible savings potential could be estimated, the savings were twice as high. These results demonstrate that pushing ultra-efficient products to market could significantly escalate carbon emission reductions and is a viable strategy for sustaining large emissions reductions through standards. The results of this analysis were used by DOE for new coverage prioritization, to identify key opportunities for product prototyping and market development, and will leverage future standards rulemakings by identifying the full scope of maximum feasible technology options. High leverage products include advances lighting systems, HVAC, and televisions. High leverage technologies include electronic lighting, heat pumps, variable speed motors, and a host of controls-related technologies.

  7. Toward Collective Impact for Climate Resilience: Maximizing Climate Change Education for Preparedness, Adaptation, and Mitigation

    2014-12-01

    Increasing the capacity of society to make informed climate decisions based on scientific evidence is imperative. While a wide range of education programs and communication efforts to improve understanding and facilitate responsible effective decision-making have been developed in recent years, these efforts have been largely disconnected. The interdisciplinary and trans-disciplinary nature of the problems and potential responses to climate change requires a broad range of expertise and a strategy that overcomes the inherent limitations of isolated programs and efforts. To extend the reach and impact of climate change education and engagement efforts, it is necessary to have a coordination that results in greater collective impact. The Collective Impact model, as described by Kania & Kramer (2011), requires five elements: 1) a common agenda; 2) shared measurement systems; 3) mutually reinforcing activities; 4) continuous communication; and 5) a well-funded backbone support organization. The CLEAN Network has facilitated a series of discussions at six professional meetings from late 2012 through spring 2014 to begin to develop and define the elements of collective impact on climate change education and engagement. These discussions have focused on getting input from the community on a common agenda and what a backbone support organization could do to help extend their reach and impact and enable a longer-term sustainability. These discussions will continue at future meetings, with the focus shifting to developing a common agenda and shared metrics. In this presentation we will summarize the outcomes of these discussions thus far, especially with respect to what activities a backbone support organization might provide to help increase the collective impact of climate change education effort and invite others to join the development of public-private partnership to improve the nations climate literacy. The cumulative input into this evolving discussion on collective

    Our goal for this supplemental issue of Pediatrics was to consider what practitioners, parents, patients, institutions, and policy-makers need to take into account to make good decisions about using complementary and alternative medicine (CAM) to treat children and to develop guidelines for appropriate use. We began by explaining underlying concepts and principles in ethical, legal, and clinical reasoning and then used case scenarios to explore how they apply and identify gaps that remain in practice and policy. In this concluding article, we review our major findings, summarize our recommendations, and suggest further research. We focus on several key areas: practitioner and patient/parent relationships; decision-making; dispute resolution; standards of practice; hospital/health facility policies; patient safety; education; and research. Ethical principles, standards, and rules applicable when making decisions about conventional care for children apply to decision-making about CAM as well. The same is true of legal reasoning. Although CAM use has seldom led to litigation, general legal principles relied on in cases involving conventional medical care provide the starting point for analysis. Similarly, with respect to clinical decision-making, clinicians are guided by clinical judgment and the best interests of their patient. Whether a therapy is CAM or conventional, clinicians must weigh the relative risks and benefits of therapeutic options and take into account their patient's values, beliefs, and preferences. Consequently, many of our observations apply to conventional and CAM care and to both adult and pediatric patients.

    2017-08-01

    Full Text Available Despite a wealth of activity across the globe in the area of longitudinal population cohorts, surprisingly little information is available on the natural biomedical history of a number of age-related neurodegenerative diseases (ND, and the scope for intervention studies based on these cohorts is only just beginning to be explored. The Joint Programming Initiative on Neurodegenerative Disease Research (JPND recently developed a novel funding mechanism to rapidly mobilize scientists to address these issues from a broad, international community perspective. Ten expert Working Groups, bringing together a diverse range of community members and covering a wide ND landscape [Alzheimer's, Parkinson's, frontotemporal degeneration, amyotrophic lateral sclerosis (ALS, Lewy-body and vascular dementia] were formed to discuss and propose potential approaches to better exploiting and coordinating cohort studies. The purpose of this work is to highlight the novel funding process along with a broad overview of the guidelines and recommendations generated by the ten groups, which include investigations into multiple methodologies such as cognition/functional assessment, biomarkers and biobanking, imaging, health and social outcomes, and pre-symptomatic ND. All of these were published in reports that are now publicly available online.

    The self-assembly of functional molecules into ordered molecular assemblies and the fulfillment of potentials unique to their nanotomesoscopic structures have been one of the central challenges in chemistry. This Feature Article provides an overview of recent progress in the field of molecular self-assembly with the focus on the triplet-triplet annihilation-based photon upconversion (TTA-UC) and supramolecular storage of photon energy. On the basis of the integration of molecular self-assembly and photon energy harvesting, triplet energy migration-based TTA-UC has been achieved in varied molecular systems. Interestingly, some molecular self-assemblies dispersed in solution or organogels revealed oxygen barrier properties, which allowed TTA-UC even under aerated conditions. The elements of molecular self-assembly were also introduced to the field of molecular solar thermal fuel, where reversible photoliquefaction of ionic crystals to ionic liquids was found to double the molecular storage capacity with the simultaneous pursuit of switching ionic conductivity. A future prospect in terms of innovating molecular self-assembly toward molecular systems chemistry is also discussed.

    Gołaś, A, Wilk, M, Stastny, P, Maszczyk, A, Pajerska, K, and Zając, A. Optimizing half squat postactivation potential load in squat jump training for eliciting relative maximal power in ski jumpers. J Strength Cond Res 31(11): 3010-3017, 2017-Training load manipulation in a single workout session can increase or decrease training effectiveness in terms of athletes' strength or power gains. In ski jumping, the complex training that elicits maximal power gains may take advantage of the postactivation potentiation (PAP) mechanism. The aim of this research was to evaluate the changes in rate of force development (RFD), rate of power development (RPD), and jump height during a complex training session consisted of the barbell half squat (Sq) as a conditioning exercise with loads ranged between 60 and 100% of 1 repetition maximum (1RM), followed by a body weight squat jump (SqJ) as a performance task. The study was conducted with 16 elite athletes from the Polish National Ski Jumping Team, age 23 ± 8 years, body mass 56 ± 9 kg, and height 172 ± 12 cm. Complex training session started with the Sq at 60% of 1RM as the conditioning exercise, followed by 3 minutes of rest and the SqJ. The conditioning barbell half Sq was performed with 70, 80, 90, and 100% of 1RM with 5 minutes of rest. The differences in RFD occurred between an SqJ following the application of 80% of 1RM and all other SqJs (p = 0.01), and in RPD between SqJ without conditioning, SqJ after 60% of 1RM and 80% of 1RM (p = 0.02). On average, the most effective load in inducing PAP during ski jumpers' SqJ training is 80% of 1RM.

    Health care professionals in pulmonary, critical care, and sleep medicine play key roles as teachers for learners of all levels in both clinical care and scientific investigation. Teaching excellence requires training in principles of adult learning and the acquisition and practice of key professional skills including assessment and feedback techniques, curriculum development, and strategies for effective teaching across venues ranging from the bedside to the lecture hall. Those interested in pursuing teaching as the focus of their academic career and basis for promotion should invest in professional development as a teacher and educator. Professional development activities include obtaining additional training as a teacher in dedicated medical education fellowships or serving as a peer observer or being observed by a fellow teacher. Numerous additional options for training as a teacher and educator are now available including resource repositories, continuing medical education courses, and online training modules. Those with an interest in medical education research may benefit from enrollment in masters or other advanced degree programs focused on the qualitative and quantitative methods and other key research skills. Aspiring clinician-educators should also seek out opportunities to participate in a community of medical educators locally, regionally, nationally, and internationally. At each of these levels, there exist opportunities to contribute to course or program design, development, and evaluation. Finally, for those interested in promotion as an academic clinician-educator, there are increasing requirements to produce academic scholarship ranging from curricular materials to journal articles focused on education and education research.

    2009-01-01

    We analyzed our data on patients undergoing transcatheter patent foramen ovale (PFO) closure to determine if the maximal potential PFO diameter (MPPD) by balloon sizing correlates with important clinical characteristics in this population. We defined stroke as a focal neurologic deficit lasting >24 h, or focal deficit of shorter duration associated with permanent MRI/CT changes consistent with a focal infarction. Parameters analyzed included age, gender, anticoagulation, hypertension, smoking, MRI/CT findings and MPPD at catheterization. We specifically analyzed the type of neurologic event (stroke/transient ischemic attack, TIA), and number of recorded preceding clinical neurologic events. In 216 consecutive patients, 167 suffered a stroke. MRI/CT changes consistent with one or more embolic events were seen in 156 patients; 49 had a clinical TIA. There was no significant difference in MPPD between stroke (11.0 +/- 3.6 mm) and TIA groups (10.9 +/- 3.9 mm; 95% confidence interval for difference: -1.33 to 1.00). MPPD did not differ between MRI/CT-positive vs. -negative strokes, and had no correlation with the number of identified pre-closure clinical neurologic events. Continued investigation is needed to determine whether other PFO characteristics, or other anatomic/physiologic parameters, may be useful to identify patients at high risk for cryptogenic stroke/TIA, even before they have their first neurologic event.

    2014-04-01

    The aim of this article is to describe the repurposing of classroom video surveillance and on-screen archives (RCVSOSA) model, which is an innovative, technology-enabled approach to continuing education in nursing. The RCVSOSA model leverages network Internet-protocol, high-definition surveillance cameras to record videos of classroom lectures that can be automatically uploaded to the Internet or converted to DVD, either in their entirety or as content-specific modules, with the production work embedded in the technology. The proposed model supports health care continuing education through the use of online assessments for focused education modules, access to archived online recordings and DVD training courses, voice-to-text transcripts, and possibly continuing education modules that may be translated into multiple languages. Potential benefits of this model include increased access to educational modules for students, instant authorship, and financial compensation for instructors and their respective organizations.

    The objective of this paper was to examine the educational potential and effectiveness of a 3 min video clip of a simulation of schizophrenia published online at YouTube. Researchers examined the 267 public comments published on the video-sharing website YouTube over 8 years by viewers of a schizophrenia simulation video titled "virtual hallucinations" made in the Second Life game platform. Comments were independently categorized into six groupings, then cooperatively finalized, and qualitatively analyzed. The six categories of style of comments were "Emotional" (n = 76), "Identification" (n = 62), "Educational Interest" (n = 45), "Mocking/Displeased" (n = 36), "Game Interest" (n = 32), and "Other" (n = 25). Without any advertising or marketing by the creators, over 194,400 views of the video were recorded in 8 years, an average of about 1500 views per month. The use of YouTube with its viral marketing potential has created a vastly amplified reach for this educational offering that would otherwise have been impossible. Qualitative analysis of publically posted comments in response to the video, which were generally positive, has led to a greater understanding of public reactions to such educational offerings. YouTube videos are already a rich source of data for psychiatric researchers, and psychiatric educators should consider posting high quality video clips on publically available social media platforms such as YouTube in order to reduce public stigma about psychiatric disorders and patients.

  5. Maximizing Amazonia's Ecosystem Services: Juggling the potential for carbon storage, agricultural yield and biodiversity in the Amazon

    The Amazon is not only an exceptionally biodiverse and carbon-rich tract of tropical forest, it is also a case study in land use change. Over the next forty years it will continue to experience pressure from an urbanizing and increasingly affluent populace: under a business-as-usual scenario, global cropland, pasture and biofuels systems will carry on expanding, while the Amazon's carbon storage potential will likely become another viable revenue source under REDD+. Balancing those competing land use pressures ought also take into account Amazonia's high - but heterogeneous - biodiversity. Knowing where Amazonia has opportunities to make efficient or optimal trade offs between carbon storage, agricultural production and biodiversity can allow policymakers to direct or influence LUC drivers. This analysis uses a spatially-explicit model that takes climate and management into account to quantify the potential agricultural yield of both the Amazon's most important agricultural commodities - sugar, soy and maize - as well as several that are going to come into increasing prominence, including palm oil. In addition, it maps the potential for carbon to be stored in forest biomass and relative species richness across Amazonia. We then compare carbon storage, agricultural yield and species richness and identify areas where efficient trade offs occur between food, carbon, and biodiversity - three critical ecosystem goods and services provided by the world's largest tropical forest.

    There is an abundance of research into cognitive processing biases in clinical psychology including the potential for applying cognitive bias modification techniques to assess the causal role of biases in maintaining anxiety and depression. Within the health psychology field, there is burgeoning interest in applying these experimental methods to assess potential cognitive biases in relation to physical health conditions and health-related behaviours. Experimental research in these areas could inform theoretical development by enabling measurement of implicit cognitive processes that may underlie unhelpful illness beliefs and help drive health-related behaviours. However, to date, there has been no systematic approach to adapting existing experimental paradigms for use within physical health research. Many studies fail to report how materials were developed for the population of interest or have used untested materials developed ad hoc. The lack of protocol for developing stimuli specificity has contributed to large heterogeneity in methodologies and findings. In this article, we emphasize the need for standardized methods for stimuli development and replication in experimental work, particularly as it extends beyond its original anxiety and depression scope to other physical conditions. We briefly describe the paradigms commonly used to assess cognitive biases in attention and interpretation and then describe the steps involved in comprehensive/robust stimuli development for attention and interpretation paradigms using illustrative examples from two conditions: chronic fatigue syndrome and breast cancer. This article highlights the value of preforming rigorous stimuli development and provides tools to aid researchers engage in this process. We believe this work is worthwhile to establish a body of high-quality and replicable experimental research within the health psychology literature.

    Full Text Available Abstract In this paper I examine the potential of blogosphere for civic education. My main argument is that in in-crisis societies such as Pakistan the blogosphere is a space where conversations and multilogues on issues that are crucial to societal regeneration are taking place. These conversations and multilogues in/through the blogosphere are democratic and inclusive in that they are not confined by the traditional articulations of ‘expertise’, privilege and subject positioning. Neither the writer nor those who participate in the ensuing conversation are or have to be experts in a disciplinary sense. They are not privileged by credentials or by their positioning in the ‘knowledge’ hierarchy. Any and all agents of the civil society can either start or engage in these multilogues, many of which directly or indirectly, focus on issues of national and societal self-regeneration.

    2017-09-29

    Maximal symmetry is a novel tool for composite pseudo Goldstone boson Higgs models: it is a remnant of an enhanced global symmetry of the composite fermion sector involving a twisting with the Higgs field. Maximal symmetry has far-reaching consequences: it ensures that the Higgs potential is finite and fully calculable, and also minimizes the tuning. We present a detailed analysis of the maximally symmetric SO(5)/SO(4) model and comment on its observational consequences.

    A hypoxic-preconditioned secretome from stem cells reportedly promotes the functional and regenerative capacity of the liver more effectively than a control secretome. However, the optimum oxygen partial pressure (pO 2 ) in the cell culture system that maximizes the therapeutic potential of the secretome has not yet been determined. We first determined the cellular alterations in adipose tissue-derived stem cells (ASCs) cultured under different pO 2 (21%, 10%, 5%, and 1%). Subsequently, partially hepatectomized mice were injected with the secretome of ASCs cultured under different pO 2 , and then sera and liver specimens were obtained for analyses. Of all AML12 cells cultured under different pO 2 , the AML12 cells cultured under 1% pO 2 showed the highest mRNA expression of proliferation-associated markers (IL-6, HGF, and VEGF). In the cell proliferation assay, the AML12 cells cultured with the secretome of 1% pO 2 showed the highest cell proliferation, followed by the cells cultured with the secretome of 21%, 10%, and 5% pO 2 , in that order. When injected into the partially hepatectomized mice, the 1% pO 2 secretome most significantly increased the number of Ki67-positive cells, reduced serum levels of proinflammatory mediators (IL-6 and TNF-α), and reduced serum levels of liver transaminases. In addition, analysis of the liver specimens indicated that injection with the 1% pO 2 secretome maximized the expression of the intermediate molecules of the PIP3/Akt and IL-6/STAT3 signaling pathways, all of which are known to promote liver regeneration. The data of this study suggest that the secretome of ASCs cultured under 1% pO 2 has the highest liver reparative and regenerative potential of all the secretomes tested here.

  18. Expectation-maximization of the potential of mean force and diffusion coefficient in Langevin dynamics from single molecule FRET data photon by photon.

    Science.gov (United States)

    Haas, Kevin R; Yang, Haw; Chu, Jhih-Wei

    2013-12-12

    The dynamics of a protein along a well-defined coordinate can be formally projected onto the form of an overdamped Lagevin equation. Here, we present a comprehensive statistical-learning framework for simultaneously quantifying the deterministic force (the potential of mean force, PMF) and the stochastic force (characterized by the diffusion coefficient, D) from single-molecule Förster-type resonance energy transfer (smFRET) experiments. The likelihood functional of the Langevin parameters, PMF and D, is expressed by a path integral of the latent smFRET distance that follows Langevin dynamics and realized by the donor and the acceptor photon emissions. The solution is made possible by an eigen decomposition of the time-symmetrized form of the corresponding Fokker-Planck equation coupled with photon statistics. To extract the Langevin parameters from photon arrival time data, we advance the expectation-maximization algorithm in statistical learning, originally developed for and mostly used in discrete-state systems, to a general form in the continuous space that allows for a variational calculus on the continuous PMF function. We also introduce the regularization of the solution space in this Bayesian inference based on a maximum trajectory-entropy principle. We use a highly nontrivial example with realistically simulated smFRET data to illustrate the application of this new method.

Our main result states that profit maximization leads to less price...... competition than utility maximization. Since profit maximization tends to raise prices, it may be regarded as beneficial for the owners as a whole. Moreover, if profit maximization is a good proxy for utility maximization, then there is no need for a general equilibrium analysis that takes the distribution...... of profits among consumers fully into account and partial equilibrium analysis suffices...

    The existence of maximally incompatible quantum observables in the sense of a minimal joint measurability region is investigated. Employing the universal quantum cloning device it is argued that only infinite dimensional quantum systems can accommodate maximal incompatibility. It is then shown that two of the most common pairs of complementary observables (position and momentum; number and phase) are maximally incompatible.

    2017-09-01

    Does every child have a fundamental right to receive a high-quality education? We propose that people's beliefs about whether "nearly everyone" or "only some people" have high intellectual potential drive their positions on education. Three studies found that the more people believed that nearly everyone has high potential, the more they viewed education as a fundamental human right. Furthermore, people who viewed education as a fundamental right, in turn (a) were more likely to support the institution of free public education, (b) were more concerned upon learning that students in the country were not performing well academically compared with students in peer nations, and (c) were more likely to support redistributing educational funds more equitably across wealthier and poorer school districts. The studies show that people's beliefs about intellectual potential can influence their positions on education, which can affect the future quality of life for countless students.

    2007-01-01

    Our previous research suggests that people reporting a stronger desire to maximize obtain worse life outcomes (Bruine de Bruin et al., 2007). Here, we examine whether this finding may be explained by the decision-making styles of self-reported maximizers. Expanding on Schwartz et al. (2002), we find that self-reported maximizers are more likely to show problematic decision-making styles, as evidenced by self-reports of less behavioral coping, greater dependence on others when making decisions...

    2006-01-01

    This work is concerned with the phenomenon of delayed loss of stability and the estimation of the maximal temperature of safe combustion. Using the qualitative theory of singular perturbations and canard techniques we determine the maximal temperature on the trajectories located in the transition region between the slow combustion regime and the explosive one. This approach is used to estimate the maximal temperature of safe combustion in multi-phase combustion models

    Using a retrospective analysis of 161 patients with amyotrophic lateral sclerosis (ALS) from the Western ALS study group (WALS) database, the sensitivity of maximal inspiratory pressure (MIP)NIV) were compared. Sixty-five per cent of patients at enrollment met the MIP criterion, compared with only 8% of patients who met the FVC criterion. There were no cases in which FVCNIV, a MIP< -60 cm H(2)O allows US clinicians to obtain non-invasive ventilatory support for patients earlier than if using the FVC criterion alone.

    2009-04-01

    Full Text Available The purpose of the study was to investigate the potential impact of distance education on a small, rural, Canadian island community. Presently, the population of small, rural island communities on the west coast of Canada are facing numerous challenges to retain and to attract permanent residents and families and to provide support and direction for those residents who wish to pursue K-12 accreditation, post-secondary education, vocational/trades training and up-grading or life-long learning. A unique set of considerations confront many of these isolated communities if they wish to engage in distance education and training. This set ranges from internet access to excessive travel by secondary students to the lack of centralized facility. For this study, a group of 48 participants were interviewed to determine their perceptions of the potential for distance education to impact on the community's educational, both academic and vocational, life-long learning and economic needs. The results indicated that there were four general areas of purported benefit: academic advancement, an improved quality of life, support for young families and a stabilizing affect on the local economy. Suggestions for the implementation of a suitable distance education resource are noted.

    We introduce the notion of maximally multipartite entangled states of n qubits as a generalization of the bipartite case. These pure states have a bipartite entanglement that does not depend on the bipartition and is maximal for all possible bipartitions. They are solutions of a minimization problem. Examples for small n are investigated, both analytically and numerically.

However, the relationship between self-reported maximizing and worse life outcomes is largely unaffected by controls for measures of other decision-making styles, decision-making competence, and demographic variables.

    1984-01-01

    Two ambiguities are noted in the definition of the concept of maximal CP violation. The phase convention ambiguity is overcome by introducing a CP violating phase in the quark mixing matrix U which is invariant under rephasing transformations. The second ambiguity, related to the parametrization of U, is resolved by finding a single empirically viable definition of maximal CP violation when assuming that U does not single out one generation. Considerable improvement in the calculation of nonleptonic weak amplitudes is required to test the conjecture of maximal CP violation. 21 references

  6. Alliances With the Potential to Transform Geoscience Education

    2005-12-01

    Geoscience problems and disciplines are inherently global, and today's opportunities for students to join the workforce also increasingly involve every country and every place on the planet. We have reached the point where the need to create global educational experiences and to make global connections are more important than ever. First, there is enormous benefit to all students if they can contribute within the context of an increasingly globalized world. Second, our primary objective as educators is to build human capacity. The reach and impact of any university is severely limited if our efforts to build this capacity is limited to students within our own classroom. The Alliances that have the potential to transform Geoscience education then have two pathways. The first is to internationalize the curriculum and to provide international educational and research opportunities. This includes: (1) establishing formal undergraduate exchange opportunities specially for the Geosciences, (2) providing opportunities within our course frameworks to enable students to gain international competences, (3) promoting international field experiences and research projects, (4) developing collaborative educational projects with international partners, and (5) creating institutional structures that are charged with promoting, proposing, reviewing, monitoring and assessing international opportunities. The second is to recognize that developing strong educational programs across the world will have a greater impact on education and research, and hence the global workforce, then for select countries to educate small populations of international students. The Alliance for Earth Science, Engineering and Development in Africa (AESEDA), created at Penn State in 2003, is establishing the partnerships with universities in Africa and with HCBUs within the U.S. that both internationalize the education of Penn State students and enable capacity building within the participating universities

    Full Text Available The objective of this study was to evaluate the potential of a Role Playing Game as an educational strategy in Undergraduate Nursing course, emphasizing its subjective implications in understanding aspects of the profession. This is a qualitative study, conducted through an evaluative research, of deployment analysis type. Nursing students of the 3rd period participated. The instrument to collection was Memories of Game, reports prepared by students after game sessions. The game is a non-traditional educational strategy that enabled approach to students through professional practice, active participation, self-reflection and reflection on professional practice. This strategy favored individualization processes, allowing students to experience situations similar to the nursing practice and exercise skills such as teamwork and creativity. The expansion of studies that address the subjective processes in higher education, through simulation games, can contribute to better design of health development processes.

    Full Text Available The growing ubiquity of smartphones and tablet devices integrated into personal, social and professional life, facilitated by expansive communication networks globally, has the potential to disrupt higher education. Academics and students are considering the future possibilities of exploiting these tools and utilising networks to consolidate and expand knowledge, enhancing learning gain. Bluetooth beacon technology has been developed by both Apple and Google as a way to situate digital information within physical spaces, and this paper reflects on a beacon intervention in a contemporary art school in higher education conducted by the authors intended to develop a situated community of practice in Art & Design. The paper describes the project, including relevant theoretical foundations and background to the beacon technology, with regards to the potential of using these devices to create a connected learning community by enhancing learning and facilitating knowledge creation in a borderless learning space.

  9. Educational innovation, learning technologies and Virtual culture potential'

    Directory of Open Access Journals (Sweden)

    2002-12-01

    Full Text Available Learning technologies are regularly associated with innovative teaching but will they contribute to profound innovations in education itself? This paper addresses the question by building upon Merlin.Donald's co-evolutionary theory of mind, cognition and culture. He claimed that the invention of technologies for storing and sharing external symbol systems, such as writing, gave rise to a 'theoretic culture' with rich symbolic representations and a resultant need for formal education. More recently, Shaffer and Kaput have claimed that the development of external and shared symbol-processing technologies is giving rise to an emerging 'virtual culture'. They argue that mathematics curricula are grounded in theoretic culture and should change to meet the novel demands of 'virtual culture' for symbol-processing and representational fluency. The generic character of their cultural claim is noted in this paper and it is suggested that equivalent pedagogic arguments are applicable across the educational spectrum. Hence, four general characteristics of virtual culture are proposed, against which applications of learning technologies can be evaluated for their innovative potential. Two illustrative uses of learning technologies are evaluated in terms of their 'virtual culture potential' and some anticipated questions about this approach are discussed towards the end of the paper.

    To investigate ways in which educational comics might provide support in dealing with feelings and attitudes towards health conditions, as well as improving understanding of factual information and to identify potential weakness of comics as a medium for health information. Semi-structured interviewees with eleven university students who either had a mental or physical health condition themselves or had a family member with a health condition. The result highlighted the potential value of comics as a format for health information. In addition to conveying factual information, comics offer opportunities for self-awareness, reassurance, empathy, companionship and a means to explore the impact of illness on family relationships. However, there are notable barriers to the greater use of comics to provide health information, namely, a lack of awareness of, and easy access to, educational comics, along with the perception that comics are exclusively light-hearted and for children. Currently, the full potential of comics in health settings is not being realised. Health information professionals may be in a position to address this issue through identifying, cataloguing, indexing and promoting comics as a legitimate format for health information. © 2016 The Author.

    Elaine Mowat

    2002-08-01

    Full Text Available The many digitisation initiatives over the last ten years have made available thousands of new resources for learning and teaching. Students of archaeology now have unprecedented access to detailed views of delicate artefacts, remote landscapes and rare maps, as well as virtual reality reconstructions, interactive panoramas, and all kinds of online archives, databases and tutorials. But does this increased access to information automatically lead to improved learning? Some of the emerging problems of this new learning landscape include information overload, poorly understood and badly implemented technologies and a lack of time and skills among educators to explore properly what's newly available. On the other hand, one of the most interesting outcomes of the introduction of the new educational technologies has been a renewed and lively debate as to what learning involves and how exactly it takes place. This article will discuss the potential of digital resources to add value to learning. It will consider current ideas about learning in order to identify some of the key ingredients of a good learning experience. It will then identify the different ways in which a digital resource base can contribute to such an experience. Specifically, it will discuss how the resources contained within SCRAN, an online multimedia resource base for education, can be used in the context of learning and teaching in archaeology. There is evidence that electronic resources are not yet being fully exploited by the current generation of educators and students. By grounding this discussion of their potential within a sound pedagogic rationale, this paper aims to promote informed use and properly placed enthusiasm for these resources.

    Unraveling the atomistic details of solid/liquid interfaces, e.g., by means of vibrational spectroscopy, is of vital importance in numerous applications, from electrochemistry to heterogeneous catalysis. Water-oxide interfaces represent a formidable challenge because a large variety of molecular and dissociated water species are present at the surface. Here, we present a comprehensive theoretical analysis of the anharmonic OH stretching vibrations at the water/ZnO(101 ¯ 0) interface as a prototypical case. Molecular dynamics simulations employing a reactive high-dimensional neural network potential based on density functional theory calculations have been used to sample the interfacial structures. In the second step, one-dimensional potential energy curves have been generated for a large number of configurations to solve the nuclear Schrödinger equation. We find that (i) the ZnO surface gives rise to OH frequency shifts up to a distance of about 4 Å from the surface; (ii) the spectrum contains a number of overlapping signals arising from different chemical species, with the frequencies decreasing in the order ν(adsorbed hydroxide) > ν(non-adsorbed water) > ν(surface hydroxide) > ν(adsorbed water); (iii) stretching frequencies are strongly influenced by the hydrogen bond pattern of these interfacial species. Finally, we have been able to identify substantial correlations between the stretching frequencies and hydrogen bond lengths for all species.

    It is argued that data from atmospheric and solar neutrino experiments point strongly to tri-maximal or bi-maximal lepton mixing. While ('optimised') bi-maximal mixing gives an excellent a posteriori fit to the data, tri-maximal mixing is an a priori hypothesis, which is not excluded, taking account of terrestrial matter effects

    Multi-model ensembles (MMEs) are powerful tools in dynamical climate prediction as they account for the overconfidence and the uncertainties related to single-model ensembles. Previous works suggested that the potential benefit that can be expected by using a MME amplifies with the increase of the independence of the contributing Seasonal Prediction Systems. In this work we combine the two MME Seasonal Prediction Systems (SPSs) independently developed by the European (ENSEMBLES) and by the Asian-Pacific (APCC/CliPAS) communities. To this aim, all the possible multi-model combinations obtained by putting together the 5 models from ENSEMBLES and the 11 models from APCC/CliPAS have been evaluated. The grand ENSEMBLES-APCC/CliPAS MME enhances significantly the skill in predicting 2m temperature and precipitation compared to previous estimates from the contributing MMEs. Our results show that, in general, the better combinations of SPSs are obtained by mixing ENSEMBLES and APCC/CliPAS models and that only a limited number of SPSs is required to obtain the maximum performance. The number and selection of models that perform better is usually different depending on the region/phenomenon under consideration so that all models are useful in some cases. It is shown that the incremental performance contribution tends to be higher when adding one model from ENSEMBLES to APCC/CliPAS MMEs and vice versa, confirming that the benefit of using MMEs amplifies with the increase of the independence the contributing models. To verify the above results for a real world application, the Grand ENSEMBLES-APCC/CliPAS MME is used to predict retrospective energy demand over Italy as provided by TERNA (Italian Transmission System Operator) for the period 1990-2007. The results demonstrate the useful application of MME seasonal predictions for energy demand forecasting over Italy. It is shown a significant enhancement of the potential economic value of forecasting energy demand when using the

    The skin sensitization potential of eight unsaturated and one saturated lipid (bio)chemicals was tested in both the LLNA and the GPMT to address the hypothesis that chemicals with unsaturated carbon-carbon double bonds may result in a higher number of unspecific (false positive) results in the LLNA compared to the GPMT. Seven substances (oleic acid, linoleic acid, linolenic acid, undecylenic acid, maleic acid, squalene and octinol) gave clear positive results in the LLNA (stimulation index (SI)> or = 3) and thus would require labelling as skin sensitizer. Fumaric acid and succinic acid gave clearly negative results. In the GPMT, besides some sporadic skin reactions, reproducible skin reactions indicating an allergic response were found in a few animals for four test substances. Based on the GPMT results, only undecylenic acid would have to be classified and labelled as a skin sensitizer according to the European Dangerous Substance Directive (67/548/EEC) (results for linoleic acid were inconclusive), while the other seven test substances would not require labelling. Possible mechanisms for unspecific skin cell stimulation and lymph node responses are discussed. In conclusion, the suitability of the LLNA for unsaturated compounds bearing structural similarity to the tested substances should be carefully considered and the GPMT should remain available as an accepted test method for skin sensitization hazard identification.

    Full Text Available Introduction and objectives: Apps can be designed to provide usage data, and most of them do. These data are usually used to map users interests and to deliver more effective ads that are more likely to result in clicks, and sales. We have applied some of these metrics to understand how can it be used to map students’ behavior and to promote a formative assessment using educational software. The purpose of a formative assessment is to monitor student learning to provide ongoing feedback that can be used by instructors and students to improve the teaching and learning process. Thus, this modality aims to help both students and instructors to identify strengths and weaknesses that need to be developed. This study aimed to describe the potential of educational apps in the formative assessment process. Material and Methods: We have implemented assessment tools embedded in three apps (ARMET, The Cell and 3D Class used to teach: 1 Metabolic Pathways; 2 Scale of the cellular structures, and 3 Concepts from techniques used in a Biochemistry Lab course. The implemented tools allow to verify on what issues there were recurring mistakes, the total number of mistakes presented, which questions they most achieved, how long they took to perform the activity and other relevant information. Results and conclusion: Educational apps can provide transparent and coherent evaluation metrics to enable instructors to systematize more consistent criteria and indicators, reducing the subjectivity of the formative assessment process and the time spent for preparation, tabulation and analysis of assessment data. This approach allows instructors to understand better where students struggle, giving to them a more effective feedback. It also helps instructor to plan interventions to help students to perform better and to achieve the learning objectives.

    Full Text Available A learning situation can be structured in different ways, as an individual, competitive, or cooperative activity. Each of these structures can be used for different purposes and can lead to different learning outcomes. This paper focuses on cooperative activity and its potential for learning in tertiary education. After defining cooperative activity (or, in a broader sense, learning in interaction and introducing the CAMS theoretical framework to analyse cooperative activity, the main discussion focuses on the theoretical reasons for the usefulness of group learning and on the research of effects of cooperative learning on cognitive (metacognitive, affective-motivational and social processes in university students. The key elements that should be established for successful cooperation are also discussed. At the end, a new direction in using cooperative activity in learning—computer supported collaborative learning (CSCL, which emerged with rapid technology development in the last two decades—is presented and discussed.

    Introduction There is a growing interest in the use of e-learning in medical education. However until recently there has been little interest in the potential environmental benefits of e-learning. This paper models various environmental outcomes that might emerge from the use of an e-learning resource (BMJ Learning) in CPD. Methods We modeled the use of e-learning as a component of CPD and evaluated the potential impact of this use on the learner's carbon footprint. We looked at a number of models - all from the perspective of a General Practitioner (GP). We assumed that all GPs completed 50 h or credits of CPD per year. Results High users of e-learning can reduce their carbon footprint - mainly by reducing their travel to face-to-face events (reducing printing also has a small beneficial effect). A high user of e-learning can reduce the carbon footprint that relates to their CPD by 18.5 kg. Discussion As global warming continues to pose a risk to human and environmental health, we feel that doctors have a duty to consider learning activities (such as e-learning) that are associated with a lower carbon footprint.

    Full Text Available The Higher Education Act is a long-awaited legal act. A number of uncompleted attempts to prepare it have been undertaken in the course of the last three years. So far without success. Having been and still being a matter of highest social priority, the renewed effort to create and subsequently to enact this act is welcome as a worthwhile and a highly productive endeavor. Welcome also are the main innovations offered by this act, particularly its conspicuous consistency with the Bologna Declaration and other internationally launched and accepted documents. The draft act follows the international documents tracing down the paths of the future development of the educational systems of the European countries and providing for their mutual compatibility. A number of other positive contributions of the draft act are singled out, such as introducing clear and rigorous criteria and procedures for accreditation and quality control, introducing a wide coverage of arts and sciences as a precondition for an institution of higher education to qualify as a university, flexibility in the regime of studying including the domestic and international mobility of the students and requirement for the schools of higher education to have large cores of permanently employed teaching staff. A much larger part of the paper is, however, devoted to critical commentaries. To begin with, the draft is produced without any participation of the private universities, which is seen as a form of discrimination. The organizational pattern of a university is laid out with insufficient clarity and the status of departments (faculties is particularly short of precision and even contradictory. The draft seems to be laden with the old bias towards excessive and potentially disastrous centralization, drastically reducing the decision making capacity of the system. The treatment of the property of the departments (faculties is found inconsistent and legally unfounded. Inconsistency is

  3. Developing maximal neuromuscular power: Part 1--biological basis of maximal power production.

    Cormie, Prue; McGuigan, Michael R; Newton, Robert U

    2011-01-01

    This series of reviews focuses on the most important neuromuscular function in many sport performances, the ability to generate maximal muscular power. Part 1 focuses on the factors that affect maximal power production, while part 2, which will follow in a forthcoming edition of Sports Medicine, explores the practical application of these findings by reviewing the scientific literature relevant to the development of training programmes that most effectively enhance maximal power production. The ability of the neuromuscular system to generate maximal power is affected by a range of interrelated factors. Maximal muscular power is defined and limited by the force-velocity relationship and affected by the length-tension relationship. The ability to generate maximal power is influenced by the type of muscle action involved and, in particular, the time available to develop force, storage and utilization of elastic energy, interactions of contractile and elastic elements, potentiation of contractile and elastic filaments as well as stretch reflexes. Furthermore, maximal power production is influenced by morphological factors including fibre type contribution to whole muscle area, muscle architectural features and tendon properties as well as neural factors including motor unit recruitment, firing frequency, synchronization and inter-muscular coordination. In addition, acute changes in the muscle environment (i.e. alterations resulting from fatigue, changes in hormone milieu and muscle temperature) impact the ability to generate maximal power. Resistance training has been shown to impact each of these neuromuscular factors in quite specific ways. Therefore, an understanding of the biological basis of maximal power production is essential for developing training programmes that effectively enhance maximal power production in the human.

    Full Text Available Introduction: the article deals with the main strategies used by foreign authorities and leading universities in order to foster the material base of the research and educational process. The article also addresses the role of international organisations and programmes in promoting education development. It is important to allocate funds of the diaspora transfers in a targeted manner to education, engaging highly skilled migrants to the joint research projects and otherwise helping to ensure that “brain drain” can be turned into a sharing of knowledge, skills and technology. Materials and Methods: the study is based on the statistic materials, allowing us to make a preliminary assessment of the scope of migrant transfers in the field of higher education, as well as to supply empirical evidence about the so-called “knowledge networks” that demonstrates their quantitative and geographical distribution. The methodological basis of the research is composed of the following methods: a comparative analysis of structural and system analysis and SWOT-analysis. Results: the study confirms the importance of such organisational forms of scientific cooperation as a major inter-university research groups and consortia. Current trends in international migration lead to the strengthening of foreign diasporas both in quantitative and qualitative terms (with regards to education or welfare. At the same time, universities are facing a set of problems related to funding, the complexity of the production of knowledge and innovation, resource-taking upgrades of educational programmes. In this situation, it is reasonable to assume that the migrants of the first and succeeding generations will be able to offset some of the costs, given that there will be a certain stim ulus. Discussion and Conclusions: the article recommends to improve the coherence of national activities under conditions of multilevel interactions with diasporas, underlines the necessity of

  11. Vacua of maximal gauged D=3 supergravities

    Fischbacher, T; Nicolai, H; Samtleben, H

    2002-01-01

    We analyse the scalar potentials of maximal gauged three-dimensional supergravities which reveal a surprisingly rich structure. In contrast to maximal supergravities in dimensions D≥4, all these theories possess a maximally supersymmetric (N=16) ground state with negative cosmological constant Λ 2 gauged theory, whose maximally supersymmetric groundstate has Λ = 0. We compute the mass spectra of bosonic and fermionic fluctuations around these vacua and identify the unitary irreducible representations of the relevant background (super)isometry groups to which they belong. In addition, we find several stationary points which are not maximally supersymmetric, and determine their complete mass spectra as well. In particular, we show that there are analogues of all stationary points found in higher dimensions, among them are de Sitter (dS) vacua in the theories with noncompact gauge groups SO(5, 3) 2 and SO(4, 4) 2 , as well as anti-de Sitter (AdS) vacua in the compact gauged theory preserving 1/4 and 1/8 of the supersymmetries. All the dS vacua have tachyonic instabilities, whereas there do exist nonsupersymmetric AdS vacua which are stable, again in contrast to the D≥4 theories

It has been substantiated that the educational potential of an individual is much more broad term compared to the education fund, because it combines both quantitative and qualitative characteristics. It has been determined that the individual educational potential represents a totality of knowledge, skills, habits of an individual, which were acquired in the process of the cognitive and educational activities, practical experience, which define its humanitarian characteristics, the value-motivational and creative capacities, social intelligence, and cause a direct impact on the labor productivity, finding its expression in the level of income. Prospects for further research in this direction will be development of the scientific-methodical foundations for evaluation of the educational potential, identifying the current trends and laws of its development

    2012-12-01

    Full Text Available This article is a review of some aspects of research on electronic portfolios with a critical analysis of the pros and cons of the invasive use of new technologies for education. Besides the creation and conceptual composition of educative portfolios that help teachers grow professionnally, this instrument implies a formatting around artifacts posited as proofs of competence, which support an uncritical realist ontology that has its limitations. Thus networked learning and personal learning environments stimulate reflective teacher learning, but possibly lead portfolio users to confuse the indicator of performance with the actual competence. Portfolio creation takes much time on other activities that could be most beneficial (and could be complementary, such as shared reflection on personal belief systems. Universalist stands and standardisation seem to take the fore while educative humane value go back stage. The new wave of distance learning creates new risks in terms of depth and quality as well as health, related to the daily use of pulsed microwaves and radio frequencies. It is suggested that a mode of control independent from the financial milieux that capitalize on these innovations should be created.

    Directory of Open Access Journals (Sweden)

    Linda Lai

    2011-06-01

    Full Text Available Despite their efforts to choose the best of all available solutions, maximizers seem to be more inclined than satisficers to regret their choices and to experience post-decisional dissonance. Maximizers may therefore be expected to change their decisions more frequently and hence exhibit lower customer loyalty to providers of products and services compared to satisficers. Findings from the study reported here (N = 1978 support this prediction. Maximizers reported significantly higher intentions to switch to another service provider (television provider than satisficers. Maximizers' intentions to switch appear to be intensified and mediated by higher proneness to regret, increased desire to discuss relevant choices with others, higher levels of perceived knowledge of alternatives, and higher ego involvement in the end product, compared to satisficers. Opportunities for future research are suggested.

  20. Implications of maximal Jarlskog invariant and maximal CP violation

    Rodriguez-Jauregui, E.; Universidad Nacional Autonoma de Mexico

    2001-04-01

    We argue here why CP violating phase Φ in the quark mixing matrix is maximal, that is, Φ=90 . In the Standard Model CP violation is related to the Jarlskog invariant J, which can be obtained from non commuting Hermitian mass matrices. In this article we derive the conditions to have Hermitian mass matrices which give maximal Jarlskog invariant J and maximal CP violating phase Φ. We find that all squared moduli of the quark mixing elements have a singular point when the CP violation phase Φ takes the value Φ=90 . This special feature of the Jarlskog invariant J and the quark mixing matrix is a clear and precise indication that CP violating Phase Φ is maximal in order to let nature treat democratically all of the quark mixing matrix moduli.

    Li, Xiaofeng; Strezov, Vladimir

    2014-01-01

    Highlights: • Energy harvesting potential of commercialized piezoelectric tiles is analyzed. • The parameters which will affect the energy harvesting efficiency are determined. • The potential could cover 0.5% of the total energy usage of the library building. • A simplified evaluation indicator is proposed to test the considered paving area. - Abstract: In this paper, potential application of a commercial piezoelectric energy harvester in a central hub building at Macquarie University in Sydney, Australia is examined and discussed. Optimization of the piezoelectric tile deployment is presented according to the frequency of pedestrian mobility and a model is developed where 3.1% of the total floor area with the highest pedestrian mobility is paved with piezoelectric tiles. The modelling results indicate that the total annual energy harvesting potential for the proposed optimized tile pavement model is estimated at 1.1 MW h/year. This potential energy generation may be further increased to 9.9 MW h/year with a possible improvement in piezoelectric energy conversion efficiency integrated into the system. This energy harvesting potential would be sufficient to meet close to 0.5% of the annual energy needs of the building. The study confirms that locating high traffic areas is critical for optimization of the energy harvesting efficiency, as well as the orientation of the tile pavement significantly affects the total amount of the harvested energy.

    The possible existence of maximal or near-maximal lepton mixing constitutes an intriguing challenge for fundamental theories of flavor. We study the phenomenological consequences of maximal and near-maximal mixing of the electron neutrino with other (x=tau and/or muon) neutrinos. We describe the deviations from maximal mixing in terms of a parameter ε(equivalent to)1-2sin 2 θ ex and quantify the present experimental status for |ε| e mixing comes from solar neutrino experiments. We find that the global analysis of solar neutrino data allows maximal mixing with confidence level better than 99% for 10 -8 eV 2 ∼ 2 ∼ -7 eV 2 . In the mass ranges Δm 2 ∼>1.5x10 -5 eV 2 and 4x10 -10 eV 2 ∼ 2 ∼ -7 eV 2 the full interval |ε| e mixing in atmospheric neutrinos, supernova neutrinos, and neutrinoless double beta decay

    We study the existence of the maximal quantum Fisher information matrix in the multi-parameter quantum estimation, which bounds the ultimate precision limit. We show that when the maximal quantum Fisher information matrix exists, it can be directly obtained from the underlying dynamics. Examples are then provided to demonstrate the usefulness of the maximal quantum Fisher information matrix by deriving various trade-off relations in multi-parameter quantum estimation and obtaining the bounds for the scalings of the precision limit.

    Full Text Available This paper presents some results of an educational innovation based on the use of ICT as a learning environment. The main aim of this study is to describe an experience based collaborative learning in virtual communities of learning and reciprocal teaching and assessing students’ knowledge. For that, we design an educational proposal with three didactic units, which includes a kit of tasks and resources for learning. This study adopts a quantitative and qualitative methodology, applying attitudes scales, interviews and analysis of messages from online discussion forums. The study involved 56 students in first year of Pedagogy. We apply a Likert scale and a semantic differential about the learning experience and the methodology used. Also we conducted semi-structured group interviews to understand the perceptions and students’ evaluations about the methodology. The results show a very positive assessment about the learning experience and the methodology used. Peer interaction is focused on resolving technical queries, although there are also other forms of collaboration focused on joint interpretation and understanding of learning activities and assessment of the learning process. The results show that the intervention centers on teacher feedback and monitoring of learning tasks, reinforcing positive actions of the students and guiding the learning process. Finally, as to the benefits received by students, the results show that not only is development of social and communication skills, but also conceptual and emotional changes related to the subject.

    Full Text Available Negli ultimi dieci anni lo sviluppo dei social media ha trasformato i modi in cui la maggior parte delle persone usa Internet. Di conseguenza molte istituzioni educative (ed educatori si ritrovano a doversi mettere al passo con questo mondo e con i suoi utenti. Dato il pressante ed esagerato interesse che circonda quest’area della tecnologia, è importante che gli educatori siano in grado di avvicinarsi ai social media in modo consapevole e competente. Le domande che questo articolo di apertura solleva sono necessariamente dirette: quali sono le caratteristiche chiave dei social media e che importanza questi rivestono oggi per l’educazione e l’apprendimento? Quali limiti impongono e quali opportunità offrono? Quali cambiamenti devono subire i processi educativi per mantenere la propria rilevanza in un’era digitale in apparente rapida evoluzione?

    2016-01-01

    Motivated by the 750 GeV diphoton excess found at LHC, we compute the maximal width into $\\gamma\\gamma$ that a neutral scalar can acquire through a loop of charged fermions or scalars as function of the maximal scale at which the theory holds, taking into account vacuum (meta)stability bounds. We show how an extra gauge symmetry can qualitatively weaken such bounds, and explore collider probes and connections with Dark Matter.

    2006-01-01

    We show the maximal violation of Bell inequalities for two d-dimensional systems by using the method of the Bell operator. The maximal violation corresponds to the maximal eigenvalue of the Bell operator matrix. The eigenvectors corresponding to these eigenvalues are described by asymmetric entangled states. We estimate the maximum value of the eigenvalue for large dimension. A family of elegant entangled states |Ψ> app that violate Bell inequality more strongly than the maximally entangled state but are somewhat close to these eigenvectors is presented. These approximate states can potentially be useful for quantum cryptography as well as many other important fields of quantum information

    2015-07-01

    Full Text Available Educational games link the motivational nature of games with learning of knowledge and skills. Here, we go beyond effects on these learning outcomes. We review two lines of evidence which indicate the currently unexplored potential of educational games to promote brain health: First, gaming with specific neurocognitive demands (e.g., executive control, and second, educational learning experiences (e.g., studying foreign languages improve brain health markers. These markers include cognitive ability, brain function, and brain structure. As educational games allow the combination of specific neurocognitive demands with educational learning experiences, they seem to be optimally suited for promoting brain health. We propose a neurocognitive approach to reveal this unexplored potential of educational games in future research.

    2017-06-01

    Nurses have historically occupied the infection preventionist (IP) role. As the knowledge and skills needed to advance the field expand, professionals from public health and the laboratory sciences have become IPs. Our study describes the characteristics of current IPs and assesses for relationships between background, certification, experience, and type of work performed. The data were drawn from an existing dataset collected in the conduct of the Association for Professionals in Infection Control and Epidemiology (APIC) MegaSurvey. Descriptive statistics were computed. Associations were calculated using χ 2 or Cochran-Mantel-Haenszel tests. Characteristics of IPs were stratified by work-related activities to allow for comparisons between groups. Of the 13,050 active APIC members, 4,079 participated in the survey (31% response rate). The primary job activity for nurses (97.9%; n = 2,434) was preventing and controlling the transmission of infectious agents or health care-associated infections, for laboratory scientists (97.5%; n = 307) it was the interpretation of surveillance data, and for public health professionals (96.1%; n = 136) it was management and communication: feedback. Infection control departments would benefit from hiring IPs with diverse education and training to address the expanding roles and responsibilities of IPs. This may facilitate the implementation of novel and innovative processes that will impact patient care. Copyright © 2017 Association for Professionals in Infection Control and Epidemiology, Inc.

    Petit dit Dariel, Odessa J; Raby, Thibaud; Ravaut, Frédéric; Rothan-Tondeur, Monique

    2013-12-01

    Shortened hospital stays, high patient acuity and technological advances demand that nurses increasingly make decisions under conditions of uncertainty and risk (Ebright et al., 2003). With rising trends towards out-patient care, nurses will need to perform complex problem-solving within a dynamic and changing environment for which there is not one clear solution (Schofield et al., 2010; Wolff et al., 2009). The development of sharp clinical reasoning skills, as well as skills in detection, monitoring, investigation and evaluation are therefore essential (Aitken et al., 2002). Yet few nursing students have long-term exposure to home-care and community situations. This is primarily due to scarce human resources and the time-consuming requirements of student supervision (Duque et al., 2008). When students are given the opportunity to experience home-care or community visits these tend to be unstructured leading to wide variations in their competencies. New pedagogical tools are needed to adequately and consistently prepare nurses for the skills they will need to care for patients outside acute care settings. Advances in Information and Communications Technologies (ICT) offer an opportunity to explore innovative pedagogical solutions that could help students develop these skills in a safe environment. A three-phased project is underway that aims to create and test a Serious Game to improve nurses' clinical reasoning and detection skills in home-care and community settings. The first phase of this project involves the development of a scenario, the game engine and the graphic design and will be the focus of this paper. The second and third phases will test the Serious Game as an educational intervention and will be reported in subsequent papers. Copyright © 2012 Elsevier Ltd. All rights reserved.

    To further reduce the sulfur dioxide emission of the entire refining process, two scenarios of acid gas or air preheats are investigated when either of them is used simultaneously with the third enrichment scheme. The maximum overall sulfur recovery efficiency and highest combustion chamber temperature is slightly higher for acid gas preheats but air preheat is more favorable because it is more benign. To the best of our knowledge, optimization of the entire GTU + enrichment section and SRU processes has not been addressed previously.

  3. Gradient Dynamics and Entropy Production Maximization

    Science.gov (United States)

    Janečka, Adam; Pavelka, Michal

    2018-01-01

    We compare two methods for modeling dissipative processes, namely gradient dynamics and entropy production maximization. Both methods require similar physical inputs-how energy (or entropy) is stored and how it is dissipated. Gradient dynamics describes irreversible evolution by means of dissipation potential and entropy, it automatically satisfies Onsager reciprocal relations as well as their nonlinear generalization (Maxwell-Onsager relations), and it has statistical interpretation. Entropy production maximization is based on knowledge of free energy (or another thermodynamic potential) and entropy production. It also leads to the linear Onsager reciprocal relations and it has proven successful in thermodynamics of complex materials. Both methods are thermodynamically sound as they ensure approach to equilibrium, and we compare them and discuss their advantages and shortcomings. In particular, conditions under which the two approaches coincide and are capable of providing the same constitutive relations are identified. Besides, a commonly used but not often mentioned step in the entropy production maximization is pinpointed and the condition of incompressibility is incorporated into gradient dynamics.

    1975-01-01

    To assure maximized oil recovery from older pools, reservoir description has been advanced by fully integrating original open-hole logs and the recently introduced interpretive techniques made available through cased-hole wireline saturation logs. A refined reservoir description utilizing normalized original wireline porosity logs has been completed in the Judy Creek Beaverhill Lake ''A'' Pool, a reefal carbonate pool with current potential productivity of 100,000 BOPD and 188 active wells. Continuous porosity was documented within a reef rim and cap while discontinuous porous lenses characterized an interior lagoon. With the use of pulsed neutron logs and production data a separate water front and pressure response was recognized within discrete environmental units. The refined reservoir description aided in reservoir simulation model studies and quantifying pool performance. A pattern water flood has now replaced the original peripheral bottom water drive to maximize oil recovery

    Cost of medical education and student indebtedness has increased dramatically. This study surveyed medical students on educational debt, educational costs, and whether indebtedness influenced career choice. Responses should impact (1) Department of Defense (DoD) recruitment of physicians and (2) future of primary care. The authors surveyed 188 incoming medical students (University of Medicine and Dentistry of New Jersey-New Jersey Medical School, Class of 2012) concerning educational indebtedness, perceptions about educational costs, and plans regarding loan repayment. Data were analyzed and expressed as mean +/- standard error. Students with loans anticipated their medical educational costs to be $155,993. 62% felt costs were "exorbitant," and 28% "appropriate." 64% planned to specialize, whereas only 9% chose primary care. 28% of students planning specialization said income potential influenced their decision. 70% of students said cost was a factor in choosing New Jersey Medical School over a more expensive school. Students anticipated taking about 10 years to repay loans. As medical educational costs and student indebtedness rise, students are choosing less costly education and career paths with higher potential future earnings. These trends will negatively impact health care availability, accessibility, and cost. DoD programs to provide financial assistance in exchange for military service are not well publicized. These findings should increase DoD recruitment opportunities.

    2011-02-01

    /or weightlifting exercises performed with loads ranging from 50% to 90% of 1RM appears to be the most potent loading stimulus for improving maximal power in complex movements. Furthermore, plyometric exercises should involve stretch rates as well as stretch loads that are similar to those encountered in each specific sport and involve little to no external resistance. These loading conditions allow for superior transfer to performance because they require similar movement velocities to those typically encountered in sport. Third, it is vital to consider the individual athlete's window of adaptation (i.e. the magnitude of potential for improvement) for each neuromuscular factor contributing to maximal power production when developing an effective and efficient power training programme. A training programme that focuses on the least developed factor contributing to maximal power will prompt the greatest neuromuscular adaptations and therefore result in superior performance improvements for that individual. Finally, a key consideration for the long-term development of an athlete's maximal power production capacity is the need for an integration of numerous power training techniques. This integration allows for variation within power meso-/micro-cycles while still maintaining specificity, which is theorized to lead to the greatest long-term improvement in maximal power.

    Bornyakov, V.G.; Polikarpov, M.I.; Syritsyn, S.N.; Schierholz, G.; Suzuki, T.

    2005-12-01

    After fixing the Maximal Abelian gauge in SU(2) lattice gauge theory we decompose the nonabelian gauge field into the so called monopole field and the modified nonabelian field with monopoles removed. We then calculate respective static potentials and find that the potential due to the modified nonabelian field is nonconfining while, as is well known, the monopole field potential is linear. Furthermore, we show that the sum of these potentials approximates the nonabelian static potential with 5% or higher precision at all distances considered. We conclude that at large distances the monopole field potential describes the classical energy of the hadronic string while the modified nonabelian field potential describes the string fluctuations. Similar decomposition was observed to work for the adjoint static potential. A check was also made of the center projection in the direct center gauge. Two static potentials, determined by projected Z 2 and by modified nonabelian field without Z 2 component were calculated. It was found that their sum is a substantially worse approximation of the SU(2) static potential than that found in the monopole case. It is further demonstrated that similar decomposition can be made for the flux tube action/energy density. (orig.)

  16. IMNN: Information Maximizing Neural Networks

    Science.gov (United States)

    Charnock, Tom; Lavaux, Guilhem; Wandelt, Benjamin D.

    2018-04-01

    This software trains artificial neural networks to find non-linear functionals of data that maximize Fisher information: information maximizing neural networks (IMNNs). As compressing large data sets vastly simplifies both frequentist and Bayesian inference, important information may be inadvertently missed. Likelihood-free inference based on automatically derived IMNN summaries produces summaries that are good approximations to sufficient statistics. IMNNs are robustly capable of automatically finding optimal, non-linear summaries of the data even in cases where linear compression fails: inferring the variance of Gaussian signal in the presence of noise, inferring cosmological parameters from mock simulations of the Lyman-α forest in quasar spectra, and inferring frequency-domain parameters from LISA-like detections of gravitational waveforms. In this final case, the IMNN summary outperforms linear data compression by avoiding the introduction of spurious likelihood maxima.

  17. Is the β phase maximal?

    International Nuclear Information System (INIS)

    Ferrandis, Javier

    2005-01-01

    The current experimental determination of the absolute values of the CKM elements indicates that 2 vertical bar V ub /V cb V us vertical bar =(1-z), with z given by z=0.19+/-0.14. This fact implies that irrespective of the form of the quark Yukawa matrices, the measured value of the SM CP phase β is approximately the maximum allowed by the measured absolute values of the CKM elements. This is β=(π/6-z/3) for γ=(π/3+z/3), which implies α=π/2. Alternatively, assuming that β is exactly maximal and using the experimental measurement sin(2β)=0.726+/-0.037, the phase γ is predicted to be γ=(π/2-β)=66.3 o +/-1.7 o . The maximality of β, if confirmed by near-future experiments, may give us some clues as to the origin of CP violation

    Full Text Available Introduction: in recent years didactic properties of electronic educational resources undergo considerable changes, nevertheless, the question of studying of such complete phenomenon as “an electronic educational resource with autodidactics elements” remains open, despite sufficient scientific base of researches of the terms making this concept. Article purpose – determination of essence of electronic educational resources with autodidactics elements. Materials and Methods: the main method of research was the theoretical analysis of the pedagogical and psychological literature on the problem under study. We used the theoretical (analysis, synthesis, comparison and generalization methods, the method of interpretation, pedagogical modeling, and empirical methods (observation, testing, conversation, interview, analysis of students’ performance, pedagogical experiment, peer review. Results: we detected the advantages of electronic educational resources in comparison with traditional ones. The concept of autodidactics as applied to the subject of research is considered. Properties of electronic educational resources with a linear and nonlinear principle of construction are studied.The influence of the principle of construction on the development of the learners’ qualities is shown. We formulated an integral definition of electronic educational resources with elements of autodidactics, namely, the variability, adaptivity and cyclicity of training. A model of the teaching-learning process with electronic educational resources is developed. Discussion and Conclusions: further development of a problem will allow to define whether electronic educational resources with autodidactics elements pedagogical potential for realization of educational and self-educational activity of teachers have, to modify technological procedures taking into account age features of students, their specialties and features of the organization of process of training of

    Full Text Available This study aims to identify the types of maxims flouted in the conversation in famous comedy show, Indonesia Lawak Club. Likewise, it also tries to reveal the speakers‘ intention of flouting the maxim in the conversation during the show. The writers use descriptive qualitative method in conducting this research. The data is taken from the dialogue of Indonesia Lawak club and then analyzed based on Grice‘s cooperative principles. The researchers read the dialogue‘s transcripts, identify the maxims, and interpret the data to find the speakers‘ intention for flouting the maxims in the communication. The results show that there are four types of maxims flouted in the dialogue. Those are maxim of quality (23%, maxim of quantity (11%, maxim of manner (31%, and maxim of relevance (35. Flouting the maxims in the conversations is intended to make the speakers feel uncomfortable with the conversation, show arrogances, show disagreement or agreement, and ridicule other speakers.

  2. People, Means, and Activities: A Conceptual Framework for Realizing the Educational Potential of Makerspaces

    Full Text Available Makerspaces are environments where individuals use technologies to make physical artifacts within a community of fellow Makers. There has been growing interest in the educational potential of Making activities which has resulted in many schools procuring tools and technologies to set up their Makerspaces. However, there is scant research investigating the efficacy of Making these newly emerging Makerspaces intended for learning. In our work, we narrow this gap in knowledge between the claimed educational potential of Making and its attainment. By synthesizing prior work and publically available data on Makerspaces, we introduce a framework to situate the educational considerations for Makerspaces and recommend directions for future research on educational Makerspaces. Being cognizant of the Maker culture having emerged outside of the academic literature, we synthesize publically available data from 53 untraditional but relevant sources. These sources include definitions of Making forwarded by 3 well-established Maker initiatives (Makerspace, Hackerspace, and Fab Lab, 18 relevant sites of Making activities across the United States, 17 sites from other countries (namely, China, India, Morocco, and Spain, and 15 Maker initiatives at schools in the United States. After proposing and detailing the framework, we recommend directions for future research to attain the potential of educational Making.

  13. A framework to evaluate the educational potential of a digital artefact for math learning

    Directory of Open Access Journals (Sweden)

    Chiappini Giampaolo

    2015-12-01

    Full Text Available This article provides a methodology with two potential applications: to prove useful to maths teachers for analysing and evaluating the educational potential of different digital artefacts and to help designers of maths learning artefacts to evaluate their design during the implementation phase. The educational potential of an artefact is considered as an entity determined by actions and representations structure available within the artefact, the interpretation and behaviour of who uses it and the features of the activity in which it is used. The proposed methodology is based on the notions of affordance, narrative and cycle of expansive learning. The methodology has been applied on AlNuSet, a system designed for supporting the teaching and learning of algebra by means of modalities of interaction that are of visual, spatial and motor nature.

  14. Maximal Abelian sets of roots

    CERN Document Server

    Lawther, R

    2018-01-01

    In this work the author lets \\Phi be an irreducible root system, with Coxeter group W. He considers subsets of \\Phi which are abelian, meaning that no two roots in the set have sum in \\Phi \\cup \\{ 0 \\}. He classifies all maximal abelian sets (i.e., abelian sets properly contained in no other) up to the action of W: for each W-orbit of maximal abelian sets we provide an explicit representative X, identify the (setwise) stabilizer W_X of X in W, and decompose X into W_X-orbits. Abelian sets of roots are closely related to abelian unipotent subgroups of simple algebraic groups, and thus to abelian p-subgroups of finite groups of Lie type over fields of characteristic p. Parts of the work presented here have been used to confirm the p-rank of E_8(p^n), and (somewhat unexpectedly) to obtain for the first time the 2-ranks of the Monster and Baby Monster sporadic groups, together with the double cover of the latter. Root systems of classical type are dealt with quickly here; the vast majority of the present work con...

  15. Learning in the working place: the educational potential of a multihead microscope in pathology postgraduate training.

    Sandmeier, Dominique; Bosman, Fred; Fiche, Maryse

    2009-03-01

    Training future pathologists is an important mission of many hospital anatomic pathology departments. Apprenticeship--a process in which learning and teaching tightly intertwine with daily work, is one of the main educational methods in use in postgraduate medical training. However, patient care, including pathological diagnosis, often comes first, diagnostic priorities prevailing over educational ones. Recognition of the unique educational opportunities is a prerequisite for enhancing the postgraduate learning experience. The aim of this paper is to draw attention of senior pathologists with a role as supervisor in postgraduate training on the potential educational value of a multihead microscope, a common setting in pathology departments. After reporting on an informal observation of senior and junior pathologists' meetings around the multihead microscope in our department, we review the literature on current theories of learning to provide support to the high potential educational value of these meetings for postgraduate training in pathology. We also draw from the literature on learner-centered teaching some recommendations to better support learning in this particular context. Finally, we propose clues for further studies and effective instruction during meetings around a multihead microscope.

  16. DOES THE HIGHER EDUCATION PROMOTE STUDENTS’ ENTREPRENEURIAL POTENTIAL IN THE SOUTH-EASTERN EUROPEAN COUNTRIES?

    Full Text Available Nowadays, there is a widespread recognition that business start-ups are a driving force of economic growth and significant job creation. Given the segmented characteristics of the labour markets, youth population is among those segments that are disproportionally affected by high and sustained unemployment. The situation with youth unemployment is particularly unfavourable in developing countries such as South-Eastern European countries where almost half of the active young population is jobless. Even though the governments in these countries have repeatedly undertaken measures for improving the position of youth on the labour markets, it seems that these endeavours have not reached the planned goals. From this perspective, it is important to analyse the potential contribution of education, and particularly the higher education to the development of entrepreneurship. The aim of this paper is to assess the role of the higher education in South-Eastern European countries in fostering the students’ entrepreneurial potential. For this purpose we have carried out a survey on representative samples of students in two universities: “St. Kliment Ohridski” (Macedonia and “Aleksander Xhuvani” (Albania. We found that considerable number of surveyed students have ideas for starting own businesses, but only a small portion of them attempted to develop their business ideas in practice. As a consequence, we can conclude that there exists a wide room for further policy recommendations that will shape directions for future reforms in the SEECs higher education systems and will improve the students’ entrepreneurial potential

    To estimate potential savings associated with the Consumer Reports Best Buy Drugs program, a national educational program that provides consumers with price and effectiveness information on prescription drugs. National data on 2006 prescription sales and retail prices paid for angiotensin-converting enzyme inhibitors (ACEIs), β-blockers, calcium channel blockers, and 3-hydroxy-3-methylglutaryl coenzyme A (HMG-coA) reductase inhibitors (statins). We converted national data on aggregate unit sales of drugs in the four classes to defined daily doses (DDD) and estimated a range of potential savings from generic and therapeutic substitution. We estimated that $2.76 billion, or 7.83 percent of sales, could be saved if use of the drugs recommended by the educational program was increased. The recommended drugs' prices were 15-65 percent lower per DDD than their therapeutic alternatives. The majority (57.4 percent) of potential savings would be achieved through therapeutic substitution. Substantial savings can be achieved through greater use of comparatively effective and lower cost drugs recommended by a national consumer education program. However, barriers to dissemination of consumer-oriented drug information must be addressed before savings can be realized. © Health Research and Educational Trust.

    The aim of this study was to evaluate the effect of an educational game that is used for teaching the mechanisms of the action potentials in cell membranes. The game was composed of pieces representing the intracellular and extracellular environments, ions, ion channels, and the Na + -K + -ATPase pump. During the game activity, the students arranged the pieces to demonstrate how the ions move through the membrane in a resting state and during an action potential, linking the ion movement with a graph of the action potential. To test the effect of the game activity on student understanding, first-year dental students were given the game to play at different times in a series of classes teaching resting membrane potential and action potentials. In all experiments, students who played the game performed better in assessments. According to 98% of the students, the game supported the learning process. The data confirm the students' perception, indicating that the educational game improved their understanding about action potentials. Copyright © 2017 the American Physiological Society.

  20. World Experience in Using Education and Science in the Process of Building the State Intellectual Potential

    2015-11-01

    Full Text Available The aim of the article is to analyze the world experience in using education and science in the processes of increasing the intellectual potential of the state and prospects of its application in Ukraine. The article describes features of the continental, Atlantic and the East Asian models of higher education management with emphasis on the key points, which can be useful for reforming the Ukrainian system of education. It has been noted that the problem of higher education quality in Ukraine lies in fundamental principles of its functioning, because development of the national education system for a long time took place under conditions of administrative system, while the European system of education is built on principles of competition and free market. On the basis of comparative characteristics of sources of finance in the United States there has been determined a dominant role of the federal government and it has been found that among the branches of science the leading positions are occupied by the life sciences. The experience of reforming science in countries of the Central and Eastern Europe, which took place on the model of functioning of the research institutes and research process in the EU countries, has been analyzed. Particular attention is paid to the successful experience of reforming the education and science in China. Taking into account the international experience the author has substantiated the directions of increasing the intellectual potential in Ukraine by deepening the integration of education and science, in particular: the creation of a wide network of research universities and conducting of a fair share of fundamental research on their base; accelerated development of public-private partnership in education and science; quick updating of the curricula adequate to the requirements of time and introduction of interdisciplinary courses; competitive financing of scientific programs with participation of the state and

    The main objectives of Norwegian petroleum policy are to maximize the value creation for the country, develop a national oil and gas industry, and to be at the environmental forefront of long term resource management and coexistence with other industries. The paper presents a graph depicting production and net export of crude oil for countries around the world for 2002. Norway produced 3.41 mill b/d and exported 3.22 mill b/d. Norwegian petroleum policy measures include effective regulation and government ownership, research and technology development, and internationalisation. Research and development has been in five priority areas, including enhanced recovery, environmental protection, deep water recovery, small fields, and the gas value chain. The benefits of internationalisation includes capitalizing on Norwegian competency, exploiting emerging markets and the assurance of long-term value creation and employment. 5 figs

    We study the synchronizability of duplex networks formed by two randomly generated network layers with different patterns of interlayer node connections. According to the master stability function, we use the smallest nonzero eigenvalue and the eigenratio between the largest and the second smallest eigenvalues of supra-Laplacian matrices to characterize synchronizability on various duplexes. We find that the interlayer linking weight and linking fraction have a profound impact on synchronizability of duplex networks. The increasingly large inter-layer coupling weight is found to cause either decreasing or constant synchronizability for different classes of network dynamics. In addition, negative node degree correlation across interlayer links outperforms positive degree correlation when most interlayer links are present. The reverse is true when a few interlayer links are present. The numerical results and understanding based on these representative duplex networks are illustrative and instructive for building insights into maximizing synchronizability of more realistic multiplex networks.

  3. VIOLATION OF CONVERSATION MAXIM ON TV ADVERTISEMENTS

    2015-07-01

    Full Text Available Maxim is a principle that must be obeyed by all participants textually and interpersonally in order to have a smooth communication process. Conversation maxim is divided into four namely maxim of quality, maxim of quantity, maxim of relevance, and maxim of manner of speaking. Violation of the maxim may occur in a conversation in which the information the speaker has is not delivered well to his speaking partner. Violation of the maxim in a conversation will result in an awkward impression. The example of violation is the given information that is redundant, untrue, irrelevant, or convoluted. Advertisers often deliberately violate the maxim to create unique and controversial advertisements. This study aims to examine the violation of maxims in conversations of TV ads. The source of data in this research is food advertisements aired on TV media. Documentation and observation methods are applied to obtain qualitative data. The theory used in this study is a maxim theory proposed by Grice (1975. The results of the data analysis are presented with informal method. The results of this study show an interesting fact that the violation of maxim in a conversation found in the advertisement exactly makes the advertisements very attractive and have a high value.

    The MOOC phenomenon contains the potential to draw a large and diverse audience with varying demands of learning possibilities. The characteristics of MOOCs are of interest from a lifelong learning perspective because they offer a possible solution to a rapid and increasing need for education...... worldwide. The very first MOOCs were not originally referred to as such; they were only labelled ‘‘massive open online courses’’ (MOOCs) in retrospect, in an attempt to describe what was distinctive and new about the ones which had already been held (Cormier 2008). These new types of courses explored new...... and interaction among participants of a course.

    Full Text Available The popularity of Facebook among university students inevitably raises questions on the educational potential of this Social Networking Site for Higher Education. From the limited literature on the instructional uses of Facebook, one can draw conflicting conclusions. Benefits were identified through the communicative potential, student participation in study groups and through informal learning, i.e. learning that takes place outside the formal structures of the learning environment. In contrast, it is also argued that the instructional benefits of Facebook are not straightforward. This phenomenographic investigation examines the perceptions of undergraduate Graphic Design students in a higher education institution in Cyprus, on the use of Facebook for teaching and learning. Characteristic of Art and Design education is the centrality of the studio and student self-reflection. Despite some literature that considers Facebook provides a viable alternative to the physical studio, the participants in this investigation expressed a preference for face-to-face instruction and consider Facebook as complimenting rather than replacing studio practices. Some participants benefited from the use of Facebook by joining support groups and exploring information relevant to their studies. Further research can investigate how Facebook can be embedded in studio-based teaching and learning.

  6. Method-Based Higher Education in Sustainability: The Potential of the Scenario Method

    Directory of Open Access Journals (Sweden)

    Richard Beecroft

    2014-05-01

    Full Text Available Both sustainability and education are challenging process-oriented objectives. When the aim is to combine both notions, as in Higher Education in Sustainability (HES, it is indispensable to first establish a common ground between them. In this paper, we characterise this common ground in terms of four aspects: future orientation, normativity, global perspective, and theory engaged in practice. Based on an analysis of the common ground, one method that is well-established in a wide range of sustainability sciences shows high potential for use in HES because it covers all four aspects in detail: the scenario method. We argue that a didactical reconstruction of the scenario method is necessary to utilise its potential and develop adequate forms of teaching in higher education. The scenario method is used to construct and analyse a set of alternative future developments to support decisions that have to be made in the present. Didactical reconstruction reveals a spectrum of objectives for which the scenario method can be employed: (1 projection; (2 teleological planning and (3 an explorative search for possibilities not yet considered. By studying and experimenting with this spectrum of objectives, students in HES can develop fundamental reflexive competencies in addressing the future in different ways that are relevant for both sustainability and education.

    Full Text Available Introduction. Nowadays, under the conditions of a general crisis of family relations, fatherhood as a social phenomenon and institution increasingly attracts the interest of researchers in various fields of humanitarian knowledge. However, Russian researchers have not treated educational potential of fatherhood in much detail due to historically developed objective reasons. Most studies are conducted not systemically; many of them describe typical problems. Moreover, previous studies of the educational potential of fatherhood have not dealt with practical recommendations for support and development of fatherhood as an educational institution.The aims of this research are: the analysis of fatherhood as an educational institution; scientific and theoretical justification for opportunities to strengthen family relations and children welfare through pedagogical support for fatherhood period.Methodology and research methods. The methodological framework of the research undertaken by authors is based on institutional approach. The relevant directions of the research on the stated problematics are highlighted on the basis of the review of the Russian and foreign scientific literature; the analysis of normative documents and generalization of social and pedagogical practices. The theoretical analysis and synthesis of the data obtained during the surveys among men from different regions ofRussia and foreign countries allowed the authors to structure typical ideas about fatherhood and to model a concept for its educational resources.Results and scientific novelty. The problems complicating mass reproduction of effective “fatherly pedagogy” are designated: system crisis of a family and masculinity; socio-economic factors resulting in the low educational motivation of fathers; lack of clear and positive ideological and valuable bases of human existence, etc. The concepts “fatherhood” and “educational potential of fatherhood” are consistently

    Potential non-physician anesthesia students gauge many different aspects of a graduate program prior to applying, but cost of education and earning potential are typically high priorities for students. Our analysis evaluated the cost of tuition for all certified registered nurse anesthetist (CRNA) and anesthesiologist assistant (AA) programs in the United States, as well as earning potential for both professions. We collected educational cost data from school websites and salary data from the Medical Group Management Association's Physician Compensation and Production Survey: 2012 Report in order to compare the two groups. We found that the median cost of public CRNA programs is $40,195 and the median cost of private programs is $60,941, with an overall median of $51,720. Mean compensation for CRNAs in 2011 was $156,642. The median cost of public AA programs is $68,210 compared with $77,155 for private AA education, and an overall median cost of $76,037. Average compensation for AAs in 2011 was $123,328. Considering these factors, nurse anesthesia school is a better choice for candidates who already possess a nursing license; however, for those prospective students who are not nurses, AA school may be a more economical choice, depending on the type and location of practice desired.

  13. The potential of neuroscience for health sciences education: towards convergence of evidence and resisting seductive allure.

    Science.gov (United States)

    de Bruin, Anique B H

    2016-12-01

    Since emergence of the field 'Educational Neuroscience' (EN) in the late nineties of the previous century, a debate has emerged about the potential this field holds to influence teaching and learning in the classroom. By now, most agree that the original claims promising direct translations to teaching and learning were too strong. I argue here that research questions in (health professions) education require multi-methodological approaches, including neuroscience, while carefully weighing what (combination of) approaches are most suitable given a research question. Only through a multi-methodological approach will convergence of evidence emerge, which is so desperately needed for improving teaching and learning in the classroom. However, both researchers and teachers should become aware of the so-called 'seductive allure' of EN; that is, the demonstrable physical location and apparent objectivity of the measurements can be interpreted as yielding more powerful evidence and warranting stronger conclusions than, e.g., behavioral experiments, where in fact oftentimes the reverse is the case. I conclude that our tendency as researchers to commit ourselves to one methodological approach and to addressing educational research questions from a single methodological perspective is limiting progress in educational science and in translation to education.

    Full Text Available Through a process-oriented analysis of the participatory art project The Hill this article explores the relevance of participatory art projects for the development of AESD – Art Education for Sustainable Development. Inspired by Felix Guattari’s Three Ecologies (2008 the analysis moves through three sub-studies delving into three different aspects of the project. Each sub-study adopts two overlapping analytical ‘lenses’: The lens of a contemporary art form (performance art, community art, and site-specific art and the lens of a related theoretical concept (subjectivation, togetherness, environment. The aim is to propose art educational ideas and strategies that stimulate students to challenge the current political, economic and environmental situation. Central questions addressed by the article are: How can educators use contemporary artistic strategies to challenge essentialist and opportunistic self-understandings? What is the potential for participatory art forms to explore alternative and more sustainable conceptions of human subjectivity? How can art education work in favour of a sense of interconnectedness between the individual, the social and the environmental dimensions of being? In conclusion, the article proposes art education as a symbolic place for carrying out art-inspired experiments with how to live our lives in more sustainable ways.

    In the field of advanced care of the complex trauma patient, there is an emerging need for focused education and training. However, several hospitals do not support further education and training in this field, and the challenge of releasing time for physicians and nurses is well-known. Educational strategies using blended learning, which combines traditional classroom methods with modern computer-assisted methods and media, have not yet been widely used. This study analysed the educational challenges and areas for improvement, according to senior physicians and nurses, and investigated the potential use of blended learning. The setting was an international course, Definitive Surgical Trauma Care (DSTC) - Military Version, part of a programme which prepares health professionals for work during extreme conditions. The sample consisted of senior physicians and nurses, participating in the course in September 2015. A survey was completed, interviews were performed and a post-course survey was conducted 18 months later in March 2017. The most difficult aspect of learning how to manage the complex trauma patient, was the lack of real practice. Even though the respondents were knowledgeable in advanced trauma, they lacked personal experience in managing complex trauma cases. Cases presented during the course represented significantly greater complexity of injury compared to those usually seen in hospitals and during military deployment. The following educational challenges were identified from the study: (1) Lack of experience and knowledge of advanced trauma care. (2) Lack of the use of blended learning as support for education and training. (3) Limited time available for preparation and reflection in the education and training process. (4) Lack of support for such education and training from home hospitals. (5) The unfulfilled requirement for multidisciplinary team-training in the military medical environment. Educational strategies and methods, such as blended

    We propose a two-component inflation model, based on maximally symmetric supergravity, where the scales of reheating and the inflation potential at the origin are decoupled. This is possible because of the second-order phase transition from SU(5) to SU(3)×SU(2)×U(1) that takes place when φ≅φcinflation at the global minimum, and leads to a reheating temperature TR≅(1015-1016) GeV. This makes it possible to generate baryon asymmetry in the conventional way without any conflict with experimental data on proton lifetime. The mass of the gravitinos is m3/2≅1012 GeV, thus avoiding the gravitino problem. Monopoles are diluted by residual inflation in the broken phase below the cosmological bounds if φcUSA.

  17. Maximizing ROI (return on information)

    2000-05-01

    The role and importance of managing information are discussed, underscoring the importance by quoting from the report of the International Data Corporation, according to which Fortune 500 companies lost $ 12 billion in 1999 due to inefficiencies resulting from intellectual re-work, substandard performance , and inability to find knowledge resources. The report predicts that this figure will rise to $ 31.5 billion by 2003. Key impediments to implementing knowledge management systems are identified as : the cost and human resources requirement of deployment; inflexibility of historical systems to adapt to change; and the difficulty of achieving corporate acceptance of inflexible software products that require changes in 'normal' ways of doing business. The author recommends the use of model, document and rule-independent systems with a document centered interface (DCI), employing rapid application development (RAD) and object technologies and visual model development, which eliminate these problems, making it possible for companies to maximize their return on information (ROI), and achieve substantial savings in implementation costs.

    Most of the digital data transmitted are carried by optical fibres, forming the great part of the national and international communication infrastructure. The information-carrying capacity of these networks has increased vastly over the past decades through the introduction of wavelength division multiplexing, advanced modulation formats, digital signal processing and improved optical fibre and amplifier technology. These developments sparked the communication revolution and the growth of the Internet, and have created an illusion of infinite capacity being available. But as the volume of data continues to increase, is there a limit to the capacity of an optical fibre communication channel? The optical fibre channel is nonlinear, and the intensity-dependent Kerr nonlinearity limit has been suggested as a fundamental limit to optical fibre capacity. Current research is focused on whether this is the case, and on linear and nonlinear techniques, both optical and electronic, to understand, unlock and maximize the capacity of optical communications in the nonlinear regime. This paper describes some of them and discusses future prospects for success in the quest for capacity. © 2016 The Authors.

  19. An educational path for the magnetic vector potential and its physical implications

    Barbieri, S; Cavinato, M; Giliberti, M

    2013-01-01

    We present an educational path for the magnetic vector potential A aimed at undergraduate students and pre-service physics teachers. Starting from the generalized Ampère–Laplace law, in the framework of a slowly varying time-dependent field approximation, the magnetic vector potential is written in terms of its empirical references, i.e. the conduction currents. Therefore, once the currents are known, our approach allows for a clear and univocal physical determination of A, overcoming the mathematical indeterminacy due to the gauge transformations. We have no need to fix a gauge, since for slowly varying time-dependent electric and magnetic fields, the ‘natural’ gauge for A is the Coulomb one. We stress the difference between our approach and those usually presented in the literature. Finally, a physical interpretation of the magnetic vector potential is discussed and some examples of the calculation of A are analysed. (paper)

    2016-11-01

    Full Text Available Towards sustainable Higher Education Institutions (HEIs, energy consumption behaviour is one of several issues that require an attention by facilities manager. Information from the behavioural aspect would be useful for facilities manager on managing the energy and determining potential energy saving. A lack of information negatively affects this aim. Hence, this paper proposes a methodology for assessing the energy consumption behaviour with the objective determining potential energy saving. The method used energy culture framework as basis and joined with centrographic approach and multiple-regression analysis. A self-administrated survey carried out involving 1400 respondents in selected HEIs. There are four types of energy use among students in HEIs namely, 'high', 'low', ‘medium’ and 'conserve' determined from the centrographic analysis. The energy consumption behaviour model was developed and tested against the holdout sample. Through the model's application, there is a vast potential for energy savings with over 55 kWh daily among the students.

    An integral part of hazard and safety assessments is the estimation of a chemical's potential to cause skin sensitization. Currently, only animal tests (OECD 406 and 429) are accepted in a regulatory context. Nonanimal test methods are being developed and formally validated. In order to gain more insight into the responses induced by eight exemplary surfactants, a battery of in vivo and in vitro tests were conducted using the same batch of chemicals. In general, the surfactants were negative in the GPMT, KeratinoSens and hCLAT assays and none formed covalent adducts with test peptides. In contrast, all but one was positive in the LLNA. Most were rated as being irritants by the EpiSkin assay with the additional endpoint, IL1-alpha. The weight of evidence based on this comprehensive testing indicates that, with one exception, they are non-sensitizing skin irritants, confirming that the LLNA tends to overestimate the sensitization potential of surfactants. As results obtained from LLNAs are considered as the gold standard for the development of new nonanimal alternative test methods, results such as these highlight the necessity to carefully evaluate the applicability domains of test methods in order to develop reliable nonanimal alternative testing strategies for sensitization testing.

    Increasing pressure is being placed on external accountability and cost efficiency in medical education and training internationally. We present an illustrative data analysis of the value-added of postgraduate medical education. We analysed historical selection (entry) and licensure (exit) examination results for trainees sitting the UK Membership of the Royal College of General Practitioners (MRCGP) licensing examination (N = 2291). Selection data comprised: a clinical problem solving test (CPST); a situational judgement test (SJT); and a selection centre (SC). Exit data was an applied knowledge test (AKT) from MRCGP. Ordinary least squares (OLS) regression analyses were used to model differences in attainment in the AKT based on performance at selection (the value-added score). Results were aggregated to the regional level for comparisons. We discovered significant differences in the value-added score between regional training providers. Whilst three training providers confer significant value-added, one training provider was significantly lower than would be predicted based on the attainment of trainees at selection. Value-added analysis in postgraduate medical education potentially offers useful information, although the methodology is complex, controversial, and has significant limitations. Developing models further could offer important insights to support continuous improvement in medical education in future.

    This study set out to explore the ways in which social media can facilitate learning in medical education. In particular we were interested in determining whether the use of Twitter during an academic conference can promote learning for participants. The Twitter transcript from the annual International Conference on Residency Education (ICRE) 2013 was qualitatively analysed for evidence of the three overarching cognitive themes: (1) preconceptions, (2) frameworks, and (3) metacognition/refl ection in regard to the National Research Council ’ s (NRC) How People Learn framework . Content analysis of the Twitter transcript revealed evidence of the three cognitive themes as related to how people learn. Twitter appears to be most effective at stimulating individuals ’ preconceptions, thereby engaging them with the new material acquired during a medical education conference. The study of social media data, such as the Twitter data used in this study, is in its infancy. Having established that Twitter does hold signifi cant potential as a learning tool during an academic conference, we are now in a better position to more closely examine the spread, depth, and sustainability of such learning during medical education meetings.

  4. Does mental exertion alter maximal muscle activation?

    Full Text Available Mental exertion is known to impair endurance performance, but its effects on neuromuscular function remain unclear. The purpose of this study was to test the hypothesis that mental exertion reduces torque and muscle activation during intermittent maximal voluntary contractions of the knee extensors. Ten subjects performed in a randomized order three separate mental exertion conditions lasting 27 minutes each: i high mental exertion (incongruent Stroop task, ii moderate mental exertion (congruent Stroop task, iii low mental exertion (watching a movie. In each condition, mental exertion was combined with ten intermittent maximal voluntary contractions of the knee extensor muscles (one maximal voluntary contraction every 3 minutes. Neuromuscular function was assessed using electrical nerve stimulation. Maximal voluntary torque, maximal muscle activation and other neuromuscular parameters were similar across mental exertion conditions and did not change over time. These findings suggest that mental exertion does not affect neuromuscular function during intermittent maximal voluntary contractions of the knee extensors.

    Area Under the ROC Curve (AUC) is often used to measure the performance of an estimator in binary classification problems. An AUC-maximizing classifier can have significant advantages in cases where ranking correctness is valued or if the outcome is rare. In a Super Learner ensemble, maximization of the AUC can be achieved by the use of an AUC-maximining metalearning algorithm. We discuss an implementation of an AUC-maximization technique that is formulated as a nonlinear optimization problem. We also evaluate the effectiveness of a large number of different nonlinear optimization algorithms to maximize the cross-validated AUC of the ensemble fit. The results provide evidence that AUC-maximizing metalearners can, and often do, out-perform non-AUC-maximizing metalearning methods, with respect to ensemble AUC. The results also demonstrate that as the level of imbalance in the training data increases, the Super Learner ensemble outperforms the top base algorithm by a larger degree.

    Feeling time-pressed has become ubiquitous. Time management strategies have emerged to help individuals fit in more of their desired and necessary activities. We provide a review of these strategies. In doing so, we distinguish between two, often competing, motives people have in managing their time: activity maximization and outcome maximization. The emerging literature points to an important dilemma: a given strategy that maximizes the number of activities might be detrimental to outcome maximization. We discuss such factors that might hinder performance in work tasks and enjoyment in leisure tasks. Finally, we provide theoretically grounded recommendations that can help balance these two important goals in time management. Published by Elsevier Ltd.

  11. On the maximal superalgebras of supersymmetric backgrounds

    International Nuclear Information System (INIS)

    Figueroa-O'Farrill, Jose; Hackett-Jones, Emily; Moutsopoulos, George; Simon, Joan

    2009-01-01

    In this paper we give a precise definition of the notion of a maximal superalgebra of certain types of supersymmetric supergravity backgrounds, including the Freund-Rubin backgrounds, and propose a geometric construction extending the well-known construction of its Killing superalgebra. We determine the structure of maximal Lie superalgebras and show that there is a finite number of isomorphism classes, all related via contractions from an orthosymplectic Lie superalgebra. We use the structure theory to show that maximally supersymmetric waves do not possess such a maximal superalgebra, but that the maximally supersymmetric Freund-Rubin backgrounds do. We perform the explicit geometric construction of the maximal superalgebra of AdS 4 X S 7 and find that it is isomorphic to osp(1|32). We propose an algebraic construction of the maximal superalgebra of any background asymptotic to AdS 4 X S 7 and we test this proposal by computing the maximal superalgebra of the M2-brane in its two maximally supersymmetric limits, finding agreement.

    2010-01-01

    We introduce the notion of a task-oriented maximally entangled state (TMES). This notion depends on the task for which a quantum state is used as the resource. TMESs are the states that can be used to carry out the task maximally. This concept may be more useful than that of a general maximally entangled state in the case of a multipartite system. We illustrate this idea by giving an operational definition of maximally entangled states on the basis of communication tasks of teleportation and superdense coding. We also give examples and a procedure to obtain such TMESs for n-qubit systems.

    A Standard Model-like Higgs near 125 GeV in the MSSM requires multi-TeV stop masses, or a near-maximal contribution to its mass from stop mixing. We investigate the maximal mixing scenario, and in particular its prospects for being realized it in potentially realistic GUT models. We work out constraints on the possible GUT-scale soft terms, which we compare with what can be obtained from some well-known mechanisms of SUSY breaking mediation. Finally, we analyze two promising scenarios in detail, namely gaugino mediation and gravity mediation with non-universal Higgs masses.

    2006-01-01

    In this paper, I have attempted to explore the role of non-nurse lecturers in adding value to nurse education programmes. In measuring "added-value" in higher education, I have embraced a more comprehensive approach including investigating the views of "Experts"; including the nurse and non-nurse lecturers themselves, and various United Kingdom stakeholders such as the Government, the Nursing and Midwifery Council and the Quality Assurance Agency. The students' views are also taken into account, when considering both the content of the programmes and how they are delivered. The complexity of "objective measurement" is considered, and the requirements of a "good" teaching experience. The potential areas for adding value include: health and social care policy priorities which encourage partnership working, the blurring of professional boundaries, and inter-professional working. Professional-specific changes embracing extended and enhanced roles and the concepts of specialist and assistant practitioners. Other areas include the Higher Education agendas including transferable skills and adult and student-centred learning. I conclude by discussing the latest policy changes and suggest that the role of the non-nurse lecturer needs more exploration to provide the best value for all.

    The maximal-clique problem, to find the maximally sized clique in a given graph, is classically an NP-complete computational problem, which has potential applications ranging from electrical engineering, computational chemistry, and bioinformatics to social networks. Here we develop a quantum algorithm to solve the maximal-clique problem for any graph G with n vertices with quadratic speedup over its classical counterparts, where the time and spatial complexities are reduced to, respectively, O (√{2n}) and O (n2) . With respect to oracle-related quantum algorithms for the NP-complete problems, we identify our algorithm as optimal. To justify the feasibility of the proposed quantum algorithm, we successfully solve a typical clique problem for a graph G with two vertices and one edge by carrying out a nuclear magnetic resonance experiment involving four qubits.

  19. Selecting for creativity and innovation potential: implications for practice in healthcare education.

    Science.gov (United States)

    Patterson, Fiona; Zibarras, Lara Dawn

    2017-05-01

    The ability to innovate is an important requirement in many organisations. Despite this pressing need, few selection systems in healthcare focus on identifying the potential for creativity and innovation and so this area has been vastly under-researched. As a first step towards understanding how we might select for creativity and innovation, this paper explores the use of a trait-based measure of creativity and innovation potential, and evaluates its efficacy for use in selection for healthcare education. This study uses a sample of 188 postgraduate physicians applying for education and training in UK General Practice. Participants completed two questionnaires (a trait-based measure of creativity and innovation, and a measure of the Big Five personality dimensions) and were also rated by assessors on creative problem solving measured during a selection centre. In exploring the construct validity of the trait-based measure of creativity and innovation, our research clarifies the associations between personality, and creativity and innovation. In particular, our study highlights the importance of motivation in the creativity and innovation process. Results also suggest that Openness to Experience is positively related to creativity and innovation whereas some aspects of Conscientiousness are negatively associated with creativity and innovation. Results broadly support the utility of using a trait-based measure of creativity and innovation in healthcare selection processes, although practically this may be best delivered as part of an interview process, rather than as a screening tool. Findings are discussed in relation to broader implications for placing more priority on creativity and innovation as selection criteria within healthcare education and training in future.

The inclusive fitness concept allows biologists to treat organisms as akin to rational agents seeking to maximize a utility function. Here we develop this idea and place it on a firm footing by employing a standard decision-theoretic methodology. We show how the principle of inclusive fitness maximization and a related principle of quasi-inclusive fitness maximization can be derived from axioms on an individual׳s 'as if preferences' (binary choices) for the case in which phenotypic effects are additive. Our results help integrate evolutionary theory and rational choice theory, help draw out the behavioural implications of inclusive fitness maximization, and point to a possible way in which evolution could lead organisms to implement it.

    Directory of Open Access Journals (Sweden)

    Alba Cervera-Lierta, José I. Latorre, Juan Rojo, Luca Rottoli

    2017-11-01

    Full Text Available We analyze how maximal entanglement is generated at the fundamental level in QED by studying correlations between helicity states in tree-level scattering processes at high energy. We demonstrate that two mechanisms for the generation of maximal entanglement are at work: i $s$-channel processes where the virtual photon carries equal overlaps of the helicities of the final state particles, and ii the indistinguishable superposition between $t$- and $u$-channels. We then study whether requiring maximal entanglement constrains the coupling structure of QED and the weak interactions. In the case of photon-electron interactions unconstrained by gauge symmetry, we show how this requirement allows reproducing QED. For $Z$-mediated weak scattering, the maximal entanglement principle leads to non-trivial predictions for the value of the weak mixing angle $\\theta_W$. Our results are a first step towards understanding the connections between maximal entanglement and the fundamental symmetries of high-energy physics.

Management of mining tourism's offer is a part of destination management organizations' processes, which within their planning are dependent on huge amounts of data as key components of their knowledge infrastructure. In Slovakia, the issue of knowledge infrastructures in tourism is approached by the Tourism Satellite Account (TSA with redeemable value to the national economy and published only as an informative report. On the other hand, regarding tourism destination management on the principles of knowledge-based economy, publicly available statistics at levels of NUTS 4-5 do not have an exact information value regards to the performance of mining tourism's offer. These facts cause lack of effective support of mining tourism in Slovakia and create significant barriers in information cooperation of tourism stakeholders. Data management and analysis may be challenging to tourism stakeholders. Information technologies offer advanced features as detection of qualitative patterns and hidden dependencies as well as the possibility of continuous study of destination's KPI evolution. Different examples around the world show that information collected in ICT knowledge infrastructures can be used as intelligent decision support tools. The tools can connect tourism and mining tourism stakeholders into a system based on knowledge and provide them with solutions to complex problems without having deep technical expertise. The results show that the issued problematic of data shortage in destination management could be solved through implementation of destination business information systems based on continuous information cooperation of relevant state authorities and stakeholders. The group of authors are members of a research team currently working on a project with the aim of developing an interactive business intelligence system for the support of complex decision making and planning in tourism market conditions of the Kosice county.

  8. E pluribus unum: the potential of collaborative learning to enhance Microbiology teaching in higher education.

    2015-12-01

    Collaborative learning, where students work together towards a shared understanding of a concept, is a well-established pedagogy, and one which has great potential for higher education (HE). Through discussion and challenging each other's ideas, learners gain a richer appreciation for a subject than with solitary study or didactic teaching methods. However, collaborative learning does require some scaffolding by the teacher in order to be successful. Collaborative learning can be augmented by the use of Web 2.0 collaborative technologies, such as wikis, blogs and social media. This article reviews some of the uses of collaborative learning strategies in Microbiology teaching in HE. Despite the great potential of collaborative learning, evidence of its use in Microbiology teaching is, to date, limited. But the potential for collaborative learning approaches to develop self-regulated, deep learners is considerable, and so collaborative learning should be considered strongly as a viable pedagogy for HE. © FEMS 2015.

    YouTube has emerged as a potential teaching tool. Studies of the teaching potential of YouTube videos have not addressed health care provider (HCP) satisfaction; a necessary prerequisite for any teaching tool. We conducted a 4-month investigation to determine HCP satisfaction with a nephrology-specific YouTube channel. The Nephrology On-Demand YouTube channel was analyzed from January 1 through April 30, 2011. Sixty-minute nephrology lectures at East Carolina University were compressed into 10-minute videos and uploaded to the channel. HCPs were asked to answer a 5-point Likert questionnaire regarding the accuracy, currency, objectivity and usefulness of the digital format of the teaching videos. Means, standard deviations and 2-sided chi-square testing were performed to analyze responses. Over 80% of HCPs considered the YouTube channel to be accurate, current and objective. A similar percentage considered the digital format useful despite the compression of videos and lack of audio. The nephrology-specific YouTube channel has the potential to educate HCPs of various training backgrounds. Additional studies are required to determine if such specialty-specific channels can improve knowledge acquisition and retention.

  10. Potential for Assessing Dynamic Problem-Solving at the Beginning of Higher Education Studies

    There is a growing demand for assessment instruments which can be used in higher education, which cover a broader area of competencies than the traditional tests for disciplinary knowledge and domain-specific skills, and which measure students' most important general cognitive capabilities. Around the age of the transition from secondary to tertiary education, such assessments may serve several functions, including selecting the best-prepared candidates for certain fields of study. Dynamic problem-solving (DPS) is a good candidate for such a role, as tasks that assess it involve knowledge acquisition and knowledge utilization as well. The purpose of this study is to validate an online DPS test and to explore its potential for assessing students' DPS skills at the beginning of their higher education studies. Participants in the study were first-year students at a major Hungarian university (n = 1468). They took five tests that measured knowledge from their previous studies: Hungarian language and literature, mathematics, history, science and English as a Foreign Language (EFL). A further, sixth test based on the MicroDYN approach, assessed students' DPS skills. A brief questionnaire explored learning strategies and collected data on students' background. The testing took place at the beginning of the first semester in three 2-h sessions. Problem-solving showed relatively strong correlations with mathematics (r = 0.492) and science (r = 0.401), and moderate correlations with EFL (r = 0.227), history (r = 0.192), and Hungarian (r = 0.125). Weak but still significant correlations were found with certain learning strategies, positive correlations with elaboration strategies, and a negative correlation with memorization strategies. Significant differences were observed between male and female students; men performed significantly better in DPS than women. Results indicated the dominant role of the first phase of solving dynamic problems, as knowledge acquisition

  13. Participation in higher education: A geodemographic perspective on the potential for further expansion in student numbers

    Science.gov (United States)

    Batey, Peter; Brown, Peter; Corver, Mark

    Higher education in England has expanded rapidly in the last ten years with the result that currently more than 30% of young people go on to university. Expansion is likely to continue following the recommendations of a national committee of inquiry (the Dearing Committee). The participation rate is known to vary substantially among social groups and between geographical areas. In this paper the participation rate is calculated using a new measure, the Young Entrants Index (YEI), and the extent of variation by region, gender and residential neighbourhood type established. The Super Profiles geodemographic system is used to facilitate the latter. This is shown to be a powerful discriminator and to offer great potential as an alternative analytical approach to the conventional social class categories, based on parental occupation, that have formed the basis of most participation studies to date.

    2013-12-01

    Medication dose calculation is one of several medication-related activities that are conducted by nurses daily. However, medication calculation skills appear to be an area of global concern, possibly because of low numeracy skills, test anxiety, low self-confidence, and low self-efficacy among student nurses. Various didactic strategies have been developed for student nurses who still lack basic mathematical competence. However, we suggest that the critical nature of these skills demands the investigation of alternative and/or supplementary didactic approaches to improve medication calculation skills and to reduce failure rates. Digital game-based learning is a possible solution because of the following reasons. First, mathematical drills may improve medication calculation skills. Second, games are known to be useful during nursing education. Finally, mathematical drill games appear to improve the attitudes of students toward mathematics. The aim of this article was to discuss common challenges of medication calculation skills in nurse education, and we highlight the potential role of digital game-based learning in this area.

    In much of the literature on business ethics and corporate social responsibility, it is more or less taken for granted that attempts to maximize profits are inherently unethical. The purpose of this paper is to investigate whether an ethical argument can be given in support of profit maximizing...... behaviour. It is argued that some form of consequential ethics must be applied, and that both profit seeking and profit maximization can be defended from a rule-consequential point of view. It is noted, however, that the result does not apply unconditionally, but requires that certain form of profit (and...... utility) maximizing actions are ruled out, e.g., by behavioural norms or formal institutions....

    BACKGROUND: Type 2 diabetes, coronary atherosclerosis, and physical fitness all correlate with insulin resistance, but the relative importance of each component is unknown. HYPOTHESIS: This study was undertaken to determine the relationship between insulin resistance, maximal oxygen uptake......, and the presence of either diabetes or ischemic heart disease. METHODS: The study population comprised 33 patients with and without diabetes and ischemic heart disease. Insulin resistance was measured by a hyperinsulinemic euglycemic clamp; maximal oxygen uptake was measured during a bicycle exercise test. RESULTS......: There was a strong correlation between maximal oxygen uptake and insulin-stimulated glucose uptake (r = 0.7, p = 0.001), and maximal oxygen uptake was the only factor of importance for determining insulin sensitivity in a model, which also included the presence of diabetes and ischemic heart disease.

    Full Text Available E-health, and in particular smartphone based technology, is increasingly becoming commonplace in healthcare. Whilst psychiatry has tapped onto these innovations for conditions such as affective disorders as well as schizophrenia and psychosis, the usage of these technologies in addiction is limited. Addiction psychiatry could harness the potential of smartphone technologies. Given the increasing incidences of substance related problems globally, and along with the normalization of the general public’s perspectives towards substances, and also in consideration of unwillingness for at-risk individuals in seeking help, the authors hope to illustrate how these issues could potentially be solved using E-Health and technological innovations. The objectives of the current perspective article are to illustrate how recent advances in smartphone-based technologies could help in terms of psycho-education, as well as in helping individuals who are at-risk users in seeking help earlier. The authors aim to illustrate how the above are possible, building on existing theory driven framework that has been extensively reviewed in previous literature. Limitations with regards to the implementation of such technologies will also be discussed.

    We study maximally multipartite-entangled states in the context of Gaussian continuous variable quantum systems. By considering multimode Gaussian states with constrained energy, we show that perfect maximally multipartite-entangled states, which exhibit the maximum amount of bipartite entanglement for all bipartitions, only exist for systems containing n=2 or 3 modes. We further numerically investigate the structure of these states and their frustration for n≤7 .

    This hybrid review-case study introduces three-dimensional (3-D) virtual worlds and their educational potential to medical/health librarians and educators. Second life (http://secondlife.com/) is perhaps the most popular virtual world platform in use today, with an emphasis on social interaction. We describe some medical and health education examples from Second Life, including Second Life Medical and Consumer Health Libraries (Healthinfo Island-funded by a grant from the US National Library of Medicine), and VNEC (Virtual Neurological Education Centre-developed at the University of Plymouth, UK), which we present as two detailed 'case studies'. The pedagogical potentials of Second Life are then discussed, as well as some issues and challenges related to the use of virtual worlds. We have also compiled an up-to-date resource page (http://healthcybermap.org/sl.htm), with additional online material and pointers to support and extend this study.

    2009-11-01

    The research aimed to explore associations between participation in 2 education programs for school-based learner drivers and subsequent road traffic offenses and crashes among a large cohort of newly licensed drivers. DRIVE is a prospective cohort study of 20822 first-year drivers aged 17 to 24 in New South Wales (NSW), Australia. Participants completed a detailed questionnaire and consented to data linkage in 2003-2004. Questionnaire items included year of participation in 2 specific education programs: a 1-day workshop-only program focusing on driving risks ("driver-focused") and a whole-of-community program also including a 1-day workshop but also longer term follow-up activities and a broader focus on reducing risk-taking and building resilience ("resilience-focused"). Survey data were subsequently linked to police-reported crash and offense data for 1996-2005. Poisson regression models that adjusted for multiple confounders were created to explore offenses and crashes as a driver (dichotomized as 0 vs >or=1) after program participation. Offenses did not differ between groups; however, whereas the driver-focused program was not associated with reduced crash risk, the resilience-focused program was associated with a 44% reduced relative risk for crash (0.56 [95% confidence interval: 0.34-0.93]). The large effect size observed and complementary findings from a comparable randomized, controlled trial in the United States suggest programs that focus more generally on reducing risks and building resilience have the potential to reduce crashes. A large, representative, randomized, controlled trial is urgently needed to confirm road safety benefits and ensure evidence-based spending and practitioner recommendations in this field.

    With reference to the discussion about shareholder versus stakeholder maximization it is argued that the normal type of maximization is in fact stakeholder-owner maxi-mization. This means maximization of the sum of the value of the shares and stake-holder benefits belonging to the dominating stakeholder-owner. Maximization of shareholder value is a special case of owner-maximization, and only under quite re-strictive assumptions shareholder maximization is larger or equal to stakeholder-owner...

    2013-07-01

    Full Text Available Across the globe, life skills education has been usually developed as part of a school initiative designed to support the healthy psychosocial development of children and adolescents. In other side, formal education system not always provides young people with good opportunities to become confident and realize their potentials. In this back drop, the biggest challenge is to identify the best strategies for providing effective life skills education to those many children who never attend secondary school or reach an age of high vulnerability and risk taking behaviour in the years immediately before reaching secondary school. Considering the situation that in different parts of the world, majority of the youths is having a mobile or will have a mobile soon, the researcher is of the view that mobile phones can be a viable option to offer life skills education to open schooling students coming from different cultural and social settings and backgrounds. Following this approach, present paper mainly discusses about: promises offered by mobile phones for life skills education; possibilities for using mobile phones as an effective, efficient and economical option for offering life skills education; and potential strategies to offer mobile phones supported life skills education to open schooling students.

    Although hundreds of articles have been published about the use of classroom response systems (CRS, clickers) in higher education, few address the use in foods, nutrition, and dietetics courses, especially upper-division, major courses. This technology has the potential to increase student engagement, motivation, assessment, and, possibly, learning. Thoughtfully designed questions may stimulate discussions, especially about challenging nutrition topics. This article presents the viability and potential benefits for the use of CRS in foods, nutrition, and dietetics classes through a brief literature summary, overview of the author's experiences, and guidance for implementing this technology.

    Hofer, M; Jansen, M; Soboll, S

    2006-02-24

    As part of the new regulations for licensing doctors there have been numerous attempts at reform by many medical faculties to consider interdisciplinary linkage of the curriculum with emphasis on teaching of small groups of students. This study was undertaken to help answer the question of how much weight should be given to the various subjects and what resources are needed for any reformed curriculum and what key areas of competence need to be given greater importance. 1029 candidates of specialist examinations of the Medical Council of North-Rhine in 2002 and 2003 filled in questionnaires to evaluate retrospectively the actual relevance of individual preclinical and clinical subjects, courses and areas of practical competence to their further medical education and related potentials for improvement in their studies. The participants were from 5 medical faculties in the North-Rhine area of Germany. They were also asked about methods of examination that were effective in aiding their learning behaviour. Those answering the questionnaire considered especially chemistry and physics as well as environmental, occupational and forensic medicine, bio-mathematics, radiotherapy and nuclear medicine among the less relevant subjects. On the other hand, anatomy, physiology, internal medicine, pharmacology and surgery were considered especially relevant. The greatest deficiencies in most of the medical curricula as taught in the North-Rhine medical courses are in the areas of competence in communication and practical clinical skills. Members of this group also pleaded for an increased use of standardized objective structured clinical examinations (OSCE).

  7. An information maximization model of eye movements

    Science.gov (United States)

    Renninger, Laura Walker; Coughlan, James; Verghese, Preeti; Malik, Jitendra

    2005-01-01

    We propose a sequential information maximization model as a general strategy for programming eye movements. The model reconstructs high-resolution visual information from a sequence of fixations, taking into account the fall-off in resolution from the fovea to the periphery. From this framework we get a simple rule for predicting fixation sequences: after each fixation, fixate next at the location that minimizes uncertainty (maximizes information) about the stimulus. By comparing our model performance to human eye movement data and to predictions from a saliency and random model, we demonstrate that our model is best at predicting fixation locations. Modeling additional biological constraints will improve the prediction of fixation sequences. Our results suggest that information maximization is a useful principle for programming eye movements.

  8. Utility Maximization in Nonconvex Wireless Systems

    CERN Document Server

    Brehmer, Johannes

    2012-01-01

    This monograph formulates a framework for modeling and solving utility maximization problems in nonconvex wireless systems. First, a model for utility optimization in wireless systems is defined. The model is general enough to encompass a wide array of system configurations and performance objectives. Based on the general model, a set of methods for solving utility maximization problems is developed. The development is based on a careful examination of the properties that are required for the application of each method. The focus is on problems whose initial formulation does not allow for a solution by standard convex methods. Solution approaches that take into account the nonconvexities inherent to wireless systems are discussed in detail. The monograph concludes with two case studies that demonstrate the application of the proposed framework to utility maximization in multi-antenna broadcast channels.

    We present evidence that loop amplitudes in maximally supersymmetric (N=4) Yang-Mills theory (SYM) beyond the planar limit share some of the remarkable structures of the planar theory. In particular, we show that through two loops, the four-particle amplitude in full N=4 SYM has only logarithmic ...... singularities and is free of any poles at infinity—properties closely related to uniform transcendentality and the UV finiteness of the theory. We also briefly comment on implications for maximal (N=8) supergravity theory (SUGRA)....

    International Nuclear Information System (INIS)

    Urbanczik, R.

    2003-01-01

    An unsupervised learning procedure based on maximizing the mutual information between the outputs of two networks receiving different but statistically dependent inputs is analyzed [S. Becker and G. Hinton, Nature (London) 355, 161 (1992)]. For a generic data model, I show that in the large sample limit the structure in the data is recognized by mutual information maximization. For a more restricted model, where the networks are similar to perceptrons, I calculate the learning curves for zero-temperature Gibbs learning. These show that convergence can be rather slow, and a way of regularizing the procedure is considered

    1999-01-01

    . In this paper we present methods for finding all maximal pairs under various constraints on the gap. In a string of length n we can find all maximal pairs with gap in an upper and lower bounded interval in time O(n log n+z) where z is the number of reported pairs. If the upper bound is removed the time reduces...... to O(n+z). Since a tandem repeat is a pair where the gap is zero, our methods can be seen as a generalization of finding tandem repeats. The running time of our methods equals the running time of well known methods for finding tandem repeats....

  17. Enhancing youth potential through Civic Service: ethical reflections arising from a geo-educational project

    Science.gov (United States)

    Rubbia, Giuliana

    2015-04-01

    Different forms of Civic Service are present in Europe. The National Civic Service (SCN) of Italy started, with a law, as an alternative to military service in 2001. It was conceived as an opportunity to people from 18 to 28 years, the volunteers, who intend to grow in social, civic, cultural and professional dimensions while performing experiences of social solidarity, national and international cooperation, protection and preservation of national heritage. Each accredited organization, which hosts SCN projects, signs up an ethical charter, regulating relationships between volunteers and the hosting organization. Summarizing, the organization must be aware 1)of putting into effect a law aimed to involve young generations in homeland defense with non violent means through services of social utility; 2) that the Civic Service wants young people to spend one year of their life in a critical phase in which they reach the responsibilities of adults; 3) that adopted working method is learning by doing, working with tutors having to increase skills and exploit the full potential of volunteers; 4) of recognizing the volunteers' right to work to reach the project's objectives, and not only for the benefits of the hosting organization; 5) that volunteers should work with well defined procedures, clear since the beginning; 6) of requiring from volunteers their full commitment to learn and responsibly participate to project's activities as well as to fully express and increase their expertise, skills and personal resources. Ethical implications emerged during an ongoing Earth Sciences education project funded by SCN and involving young volunteers at Istituto Nazionale di Geofisica e Vulcanologia (INGV). According to SCN's ethical charter, in this case the challenge is to welcome a group of young people in a public research organization, and to integrate them in the limited time lapse of one year. The European Charter for Researchers came as a valuable help. Its principles

    Sharma, Kavya; George, Sunil; Zodpey, Sanjay

    2011-01-01

    Continuing education of health care providers plays an important role in producing a health work force that is efficient and effective. In India public health education has primarily relied on conventional methods of training. However, such methods have limitations in equipping the health workforce of a vast and varied country like India. This paper analyzes the current status of distance education in public health and lists the various courses that are presently available in India through the distance education mode. Presently 25 institutions in India are offering 69 courses in various domains of public health through distance education. The providers of these programs comprised both government and private educational institutions. This paper also points out the role and importance of various stakeholders in the design and delivery of distance education programs in public health and raises key areas that need attention in the governance of such programs. It urges the use of digital technology in the delivery of distance education programs and points out how distance education that is designed and delivered using the latest technology could address the current gap in training human resources for health in India.

    Although higher education has been associated with lower mortality rates in many studies, the effect of potential improvements in educational distribution on future mortality levels is unknown. We therefore estimated the impact of projected increases in higher education on mortality in European populations. We used mortality and population data according to educational level from 21 European populations and developed counterfactual scenarios. The first scenario represented the improvement in the future distribution of educational attainment as expected on the basis of an assumption of cohort replacement. We estimated the effect of this counterfactual scenario on mortality with a 10-15-year time horizon among men and women aged 30-79 years using a specially developed tool based on population attributable fractions (PAF). We compared this with a second, upward levelling scenario in which everyone has obtained tertiary education. The reduction of mortality in the cohort replacement scenario ranged from 1.9 to 10.1% for men and from 1.7 to 9.0% for women. The reduction of mortality in the upward levelling scenario ranged from 22.0 to 57.0% for men and from 9.6 to 50.0% for women. The cohort replacement scenario was estimated to achieve only part (4-25% (men) and 10-31% (women)) of the potential mortality decrease seen in the upward levelling scenario. We concluded that the effect of on-going improvements in educational attainment on average mortality in the population differs across Europe, and can be substantial. Further investments in education may have important positive side-effects on population health. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available This study used a revised Conversational Violations Test to examine Gricean maxim violations in 4- to 6-year-old Japanese children and adults. Participants’ understanding of the following maxims was assessed: be informative (first maxim of quantity, avoid redundancy (second maxim of quantity, be truthful (maxim of quality, be relevant (maxim of relation, avoid ambiguity (second maxim of manner, and be polite (maxim of politeness. Sensitivity to violations of Gricean maxims increased with age: 4-year-olds’ understanding of maxims was near chance, 5-year-olds understood some maxims (first maxim of quantity and maxims of quality, relation, and manner, and 6-year-olds and adults understood all maxims. Preschoolers acquired the maxim of relation first and had the greatest difficulty understanding the second maxim of quantity. Children and adults differed in their comprehension of the maxim of politeness. The development of the pragmatic understanding of Gricean maxims and implications for the construction of developmental tasks from early childhood to adulthood are discussed.

    2017-07-01

    Full Text Available Didactic potential of upbringing pupils in educational institutions of the Diaspora by means of artistic word has been analyzed. The attention is paid to the function of art – Ukrainian literature, which promotes the formation of fully developed personality, their preparation for the conscious and active labour activity, and therefore upbringing is closely connected with life. It is cleared out that when plunging into the system of the artistic world, the pupil learns from the life of the main positive characters how to live in the society and to be useful, because textbooks and manuals on the native literature, readers in the Diaspora provide the basis for children to learn the behaviour of consciousness, and the latter, as it is known, depends on the construction of the world in themselves, that is called the worldview. It is proved that the powerful moral-educational and artistic-aesthetic potential of Ukrainian literature is being implemented in the books of Western Ukrainian Diaspora with the aim of ethnic and cultural enrichment of pupils and above all the formation of national consciousness of Ukrainian children, active choice of their values of national spirituality. It is established that the didactic potential of the upbringing of pupils by means of artistic word allows instilling love to the native language, to Ukraine, and thus it slows down the process of assimilation. On the basis of the study of the scientific-pedagogical heritage of emigration teachers-philologists, the theoretical approaches and practice of schoolchildren education by means of the word have been analyzed, the significance of their experience for the modern educational practice has been substantiated. The system of education of schoolchildren by means of the word, which has been developed over the years, is actual for the development of pedagogical science and practice. The analysis of pedagogical practice, accumulated didactic potential of upbringing pupils in

  11. Potentials of Web 2.0 for Diabetes Education of Adolescent Patients

    Science.gov (United States)

    Shabestari, Omid; Roudsari, Abdul

    Diabetes is a very common chronic disease which produces compli-cations in almost all body organs and consumes a huge amount of the health budget. Although education has proved to be useful in diabetes management, there is a great need to improve the availability of these courses for the increasing number of diabetic patients. E-learning can facilitate this service, but the current education system should be tailored towards e-learning standards. Amongst diabetic patients, adolescents as computer natives are suggested as the best target to e-learning diabetes education. With regards to its features, Web 2.0 can be a very good technology to build a framework for diabetes education and consequent evaluation of this education.

  12. SUSTAINABLE DEVELOPMENT IN THE CONTEXT OF EDUCATION: SWEDISH REALITIES AND RUSSIAN POTENTIAL

    Full Text Available The goal of this paper is to discuss current problems of education for sustainable development, i.e. a global educational innovation that is actively growing in the new century. In Sweden, which has extensive experience in ecological education, education for sustainable development is considered a national model for the creation of the foundation for SD. In Russia, difficulties exist in defining and achieving SD objectives. It has been demonstrated that cooperation between Russia and Sweden in the field of ESD may prove to be very successful. Such cooperation is based on historical, cultural, and geographical factors. Examples of successful cooperation are joint educational projects aimed at improving the ESD framework and its practical implementation. The results of joint projects between the two countries have been analyzed in the context of mutual interests of Russia and Sweden and new goals for cooperation have been outlines.

  13. Teaching for more effective learning: Seven maxims for practice

    International Nuclear Information System (INIS)

    McMahon, Tim

    2006-01-01

    Starting from the assumption that deep learning, which seeks lasting mastery over a subject, is more desirable in professional education than shallow learning, which is merely designed to pass academic assessments, this paper suggests ways in which teachers in higher education can encourage the former. Noting that students tend to adopt either a shallow or deep approach in response to their experiences in the classroom and their understanding of what the assessment regime requires, it argues that, as a consequence, it ought to be possible to prompt more students to adopt deep learning approaches by manipulating teaching and assessment strategies. The literature on teaching and learning is explored in order to derive maxims of good practice which, if followed, can reasonably be expected to promote deep learning and discourage surface learning. It is argued that this will lead to more effective preparation for the real world of professional practice

    In Germany, educational deficits or potential benefits involved in global health education have not been analysed till now. We assess the importance medical students place on learning about social determinants of health (SDH) and assess their knowledge of global health topics in relation to (i) mobility patterns, their education in (ii) tropical medicine or (iii) global health. Cross-sectional study among medical students from all 36 medical schools in Germany using a web-based, semi-structured questionnaire. Participants were recruited via mailing-lists of students' unions, all medical students registered in 2007 were eligible to participate in the study. We captured international mobility patterns, exposure to global health learning opportunities and attitudes to learning about SDH. Both an objective and subjective knowledge assessment were performed. 1126 online-replies were received and analysed. International health electives in developing countries correlated significantly with a higher importance placed on all provided SDH (p ≤ 0.006). Participation in tropical medicine (p educational system' (p = 0.007) and the 'health system structure' (p = 0.007), while the item 'politics' was marginally significant (p = 0.053).In the knowledge assessment students achieved an average score of 3.6 (SD 1.5; Mdn 4.0), 75% achieved a score of 4.0 or less (Q25 = 3.0; Q75 = 4.0) from a maximum achievable score of 8.0. A better performance was associated with international health electives (p = 0.032), participation in tropical medicine (p = 0.038) and global health (p = 0.258) courses. The importance medical students in our sample placed on learning about SDH strongly interacts with students' mobility, and participation in tropical medicine and global health courses. The knowledge assessment revealed deficits and outlined needs to further analyse education gaps in global health. Developing concerted educational interventions aimed at fostering students' engagement with SDH

    Arboix-Calas, France; Lemonnier, Geneviève

    2016-01-01

    Nutrition education in schools must be based on a collaborative approach between teachers and school nurses. The objective of this study was to compare the nutrition education representations and practices of primary school teachers and school nurses in the Languedoc-Roussillon region in the South of France. We used the theoretical framework of complexity, which is particularly suited to multifactorial phenomena such as nutrition education. We interviewed 112 primary school teachers and 33 school nurses about three aspects of their nutrition education representations and practices: actors, content and place of nutrition education at school. Nurses had a more comprehensive and complex approach to nutrition education, including a collaborative approach. However, teachers had a fairly simplistic view of nutrition education and their practice took little account of the psychosocial dimensions of nutrition and a collaborative approach. Nurses could be resources for teachers to help them change their approach to health by transforming a purely biomedical approach to health and nutrition into a more comprehensive approach, particularly taking into account in its psychological and social dimensions, which would be more appropriate to address the growing prevalence of diet-related chronic diseases in France today.

    Power, Julianne M; Braun, Kathryn L; Bersamin, Andrea

    Estimate media technology use in Alaska Native communities to inform the feasibility of technology-based nutrition education. A self-administered questionnaire was mailed to a random selection of about 50% of Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) authorized representatives in remote Alaska Native communities (n = 975). Media technology use, interest in media technology-based nutrition education, and potential barriers were assessed. Chi-square tests were used to investigate associations among technology use, age, and education. Technology use was common among respondents (n = 368); use was significantly more common among younger age groups and participants with a higher level of education. Smartphone (78.8%) and Facebook (95.8%) use was comparable to national averages, but having a computer at home (38.4%) was much less likely. Less than 50% of participants have Internet access at home. Findings shed light on new opportunities for WIC and other programs to deliver nutrition education to Alaska Native people in remote communities.

    The objective was to determine to what extent daily physical education can be implemented in primary schools, what barriers exist and how to overcome the mentioned barriers. Moreover, it was analysed to what extent daily physical education is accepted by teachers, external trainers, parents and students. Semi-structured interviews with parents (n=7), teachers (n=5) and external trainers (n=6) of the intervention schools. The intervention students (n=44) were surveyed within focus groups. All surveyed groups appraised the implementation of daily school sports as successful. The cooperation between the schools and the sports club should be maintained during a comprehensive implementation of daily physical education. Besides an improved lessons quality teachers and external trainers reported an improved social behaviour of the children. Parents perceived positive effects on the child development. All groups believe that daily physical education increases the enjoyment of children in sports. As a certain barrier a lack of resources (e. g., facilities, equipment, financial resources) in the schools were mentioned. The cooperation between the schools and the sports club proved to be an applicable model to implement daily physical education. The combination of teachers and external trainers can contribute to a higher lesson quality. Considering the perceived potentials of daily physical education by all surveyed groups, a comprehensive implementation of systematic daily physical activity promotion in the primary school setting should be tapped more strongly in future. © Georg Thieme Verlag KG Stuttgart · New York.

  18. LOAD THAT MAXIMIZES POWER OUTPUT IN COUNTERMOVEMENT JUMP

    2016-02-01

    Full Text Available ABSTRACT Introduction: One of the main problems faced by strength and conditioning coaches is the issue of how to objectively quantify and monitor the actual training load undertaken by athletes in order to maximize performance. It is well known that performance of explosive sports activities is largely determined by mechanical power. Objective: This study analysed the height at which maximal power output is generated and the corresponding load with which is achieved in a group of male-trained track and field athletes in the test of countermovement jump (CMJ with extra loads (CMJEL. Methods: Fifty national level male athletes in sprinting and jumping performed a CMJ test with increasing loads up to a height of 16 cm. The relative load that maximized the mechanical power output (Pmax was determined using a force platform and lineal encoder synchronization and estimating the power by peak power, average power and flight time in CMJ. Results: The load at which the power output no longer existed was at a height of 19.9 ± 2.35, referring to a 99.1 ± 1% of the maximum power output. The load that maximizes power output in all cases has been the load with which an athlete jump a height of approximately 20 cm. Conclusion: These results highlight the importance of considering the height achieved in CMJ with extra load instead of power because maximum power is always attained with the same height. We advise for the preferential use of the height achieved in CMJEL test, since it seems to be a valid indicative of an individual's actual neuromuscular potential providing a valid information for coaches and trainers when assessing the performance status of our athletes and to quantify and monitor training loads, measuring only the height of the jump in the exercise of CMJEL.

    Branch, B. D.

    2008-12-01

    The effort to promote more geosciences numbers and greater diversity should reference considerations of federal policy. In congruence, institutions need to include geosciences education in the K-12 curriculum in order to increase the numbers of geoscientists and to increase diversity among geoscientists. For example, No Child Left Behind stated public entities should, ""(1) to carry out programs that prepare prospective teachers to use advanced technology to prepare all students to meet challenging", section 1051 sub section 221. Moreover, Executive Order 12906, the Spatial Data Infrastructure Act, requires all federal agencies to manage their spatial data. Such compliance may influence the job market, education and policy makers to see that spatial thinking transcends the standard course of study. Namely, educational leadership and policy have to be a vital aid to augment the geosciences experience through the K-12 experience and as an inclusion activity in the standard course of study agenda. A simple endorsement by the National Academy of Sciences (2006), in their work titled Learning to think spatially: GIS as a support system in the K-12 curriculum, who stated, "Spatial thinking can be learned, and it can and should be taught at all levels in the education system" (p.3). Such may not be enough to gain the attention and time consideration of educational leadership. Therefore, the challenge for progressive advocates of geosciences is that some may have to consider educational leadership as new frontier to push such policy and research issues.

  3. Learning to Escape: Prison Education, Rehabilitation and the Potential for Transformation

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available This article examines motivations behind participation in education based on interviews with Irish prisoners. It begins by considering the relationship between education and rehabilitation, especially the latter’s re-emergence in a more authoritarian form. Drawing on results from the research, this article argues that the educational approach, culture and atmosphere are particularly important in creating a learning environment in prison. It makes the case that educational spaces which allow students to voluntarily engage in different types of learning, at their own pace, at a time of their choosing, can be effective in encouraging prisoners to engage in critical reflection and subsequently, to move away from criminal activity. It locates education in prison within a wider context and concludes that while prison education can work with, it needs to distinguish itself from, state-sponsored rehabilitation programmes and stand on the integrity of its profession, based on principles of pedagogy rather than be lured into the evaluative and correctional milieu of modern penality.

  4. Maximal frustration as an immunological principle.

    de Abreu, F Vistulo; Mostardinha, P

    2009-03-06

    A fundamental problem in immunology is that of understanding how the immune system selects promptly which cells to kill without harming the body. This problem poses an apparent paradox. Strong reactivity against pathogens seems incompatible with perfect tolerance towards self. We propose a different view on cellular reactivity to overcome this paradox: effector functions should be seen as the outcome of cellular decisions which can be in conflict with other cells' decisions. We argue that if cellular systems are frustrated, then extensive cross-reactivity among the elements in the system can decrease the reactivity of the system as a whole and induce perfect tolerance. Using numerical and mathematical analyses, we discuss two simple models that perform optimal pathogenic detection with no autoimmunity if cells are maximally frustrated. This study strongly suggests that a principle of maximal frustration could be used to build artificial immune systems. It would be interesting to test this principle in the real adaptive immune system.

    2011-03-01

    The aim of this study was to determine the influence of punch type (Jab, Cross, Lead Hook and Reverse Hook) and punch modality (Single maximal, 'In-synch' and 'Out of synch' combination) on punch speed and delivery time. Ten competition-standard volunteers performed punches with markers placed on their anatomical landmarks for 3D motion capture with an eight-camera optoelectronic system. Speed and duration between key moments were computed. There were significant differences in contact speed between punch types (F(2,18,84.87) = 105.76, p = 0.001) with Lead and Reverse Hooks developing greater speed than Jab and Cross. There were significant differences in contact speed between punch modalities (F(2,64,102.87) = 23.52, p = 0.001) with the Single maximal (M+/- SD: 9.26 +/- 2.09 m/s) higher than 'Out of synch' (7.49 +/- 2.32 m/s), 'In-synch' left (8.01 +/- 2.35 m/s) or right lead (7.97 +/- 2.53 m/s). Delivery times were significantly lower for Jab and Cross than Hook. Times were significantly lower 'In-synch' than a Single maximal or 'Out of synch' combination mode. It is concluded that a defender may have more evasion-time than previously reported. This research could be of use to performers and coaches when considering training preparations.

    2004-01-01

    Over the next twenty years, a wave of change is occurring in the space-based scientific remote sensing community. While the fundamental limits in the spatial and angular resolution achievable in spacecraft have been reached, based on today s technology, an expansive new technology base has appeared over the past decade in the area of Distributed Space Systems (DSS). A key subset of the DSS technology area is that which covers precision formation flying of space vehicles. Through precision formation flying, the baselines, previously defined by the largest monolithic structure which could fit in the largest launch vehicle fairing, are now virtually unlimited. Several missions including the Micro-Arcsecond X-ray Imaging Mission (MAXIM), and the Stellar Imager will drive the formation flying challenges to achieve unprecedented baselines for high resolution, extended-scene, interferometry in the ultraviolet and X-ray regimes. This paper focuses on establishing the feasibility for the formation control of the MAXIM mission. MAXIM formation flying requirements are on the order of microns, while Stellar Imager mission requirements are on the order of nanometers. This paper specifically addresses: (1) high-level science requirements for these missions and how they evolve into engineering requirements; and (2) the development of linearized equations of relative motion for a formation operating in an n-body gravitational field. Linearized equations of motion provide the ground work for linear formation control designs.

  11. Cardiorespiratory Coordination in Repeated Maximal Exercise

    2017-06-01

    Full Text Available Increases in cardiorespiratory coordination (CRC after training with no differences in performance and physiological variables have recently been reported using a principal component analysis approach. However, no research has yet evaluated the short-term effects of exercise on CRC. The aim of this study was to delineate the behavior of CRC under different physiological initial conditions produced by repeated maximal exercises. Fifteen participants performed 2 consecutive graded and maximal cycling tests. Test 1 was performed without any previous exercise, and Test 2 6 min after Test 1. Both tests started at 0 W and the workload was increased by 25 W/min in males and 20 W/min in females, until they were not able to maintain the prescribed cycling frequency of 70 rpm for more than 5 consecutive seconds. A principal component (PC analysis of selected cardiovascular and cardiorespiratory variables (expired fraction of O2, expired fraction of CO2, ventilation, systolic blood pressure, diastolic blood pressure, and heart rate was performed to evaluate the CRC defined by the number of PCs in both tests. In order to quantify the degree of coordination, the information entropy was calculated and the eigenvalues of the first PC (PC1 were compared between tests. Although no significant differences were found between the tests with respect to the performed maximal workload (Wmax, maximal oxygen consumption (VO2 max, or ventilatory threshold (VT, an increase in the number of PCs and/or a decrease of eigenvalues of PC1 (t = 2.95; p = 0.01; d = 1.08 was found in Test 2 compared to Test 1. Moreover, entropy was significantly higher (Z = 2.33; p = 0.02; d = 1.43 in the last test. In conclusion, despite the fact that no significant differences were observed in the conventionally explored maximal performance and physiological variables (Wmax, VO2 max, and VT between tests, a reduction of CRC was observed in Test 2. These results emphasize the interest of CRC

  12. Redefining the measure of medical education: harnessing the transformative potential of MEPI.

    Kim, Jim Yong; Evans, Timothy G

    2014-08-01

    The massive shortage of skilled health professionals in many parts of the world is a critical constraint to achieving the goal of universal health coverage. This shortfall reflects a generalized failure of leadership: a chronic misalignment between the direction of health professional education and the health goals of society. The Medical Education Partnership Initiative (MEPI) and Nurse Education Partnership Initiative (NEPI) are outliers in this regard through their deliberate efforts to revitalize education to address the pressing health needs of Sub-Saharan Africa. Inspired by this example, the World Bank Group sees health professional education institutions (HPEIs) as an insufficiently tapped source of knowledge and know-how for accelerating health achievement. The challenge ahead is to articulate clearer expectations for HPEI performance, marshal more and smarter investments across the public and private sectors, prioritize accountability, incentivize innovation, and strengthen global learning and evaluation. It is time to build on the positive legacy of MEPI/NEPI and ensure that the conditions are made available for a new generation of health workers with the competencies to meet the health and development challenges of today and tomorrow.

    McClimens, Alex; Scott, Rachel

    2007-04-01

    Learning disability nurse education, with a current emphasis on inclusive practice and a history of listening to the person with the disability, is well placed to take advantage of more 'experimental' forms of classroom teaching. In this article we argue for the use of forum theatre as a method of addressing topics from practice within an educational setting. Based on our emergent and exploratory work with students we detail at length the theoretical background that supports such an approach and contextualise the issues with reference to a short piece of drama we have used successfully with different student groups. We feel that the success of this method is due to the involvement of students in directing their own education as well as the inclusion of individuals labelled with learning disability as an integral part of the process.

    Full Text Available Differences on chronological age within a peer/age group are known as Relative Age, and its consecuences as Relative Age Effec (RAE. This article is a review of the most relevant publications in both the educative and sportive contexts. The decision of reviewing both contexts in the same article is based on the existence of many points in common between them. Furthermore when research is made on youth sport, all the participants are at the same time in the educational system. The hypothesis of the origin of RAE and possible solutions are discussed and analysed at the end of the paper. Besides the objective of compiling and analyse what literature says about RAE, this article has the aim of raisig awareness about this problem and wish of intervention in educators and sportive managers.

    2017-11-01

    Full Text Available The urgency of the topic is stipulated by the importance of the problem of moral education of children in the family with the direct involvement of parents as the first educators of a child. The purpose of the study is to identify and describe the educational potential of a family in the moral development of a child (on the example of the USA. The results of the study showed that education of moral qualities of the child in the family by the parents will be effective if the following recommendations of teachers and psychologists are observed: – in the interpretation of meaning and social significance of moral concepts a parent should take into account the age level of intellectual development of the child; – a parent should use the educational power of personal positive example, observing moral standards that the child should learn; – a parent should involve all family members in a child’s life to maintain the homely atmosphere that will strengthen the concept of “home” in the child’s consciousness; – a parent should constantly engage a child in joint activities to provide the child in the future with happy family childhood memories; – a parent should give a competent assessment of the child’s behavior and direct educational impact of moral assessment in the formation of correct behavior of the child. The scope of the results of the study. The results of the study can be used in the process of developing new technologies, methods and techniques of psycho-pedagogical assistance to families in the matters of moral education of children.

    2012-08-01

    Maximal oxygen uptake is generally accepted as the most valid and reliable index of cardiorespiratory fitness and functional aerobic capacity. The exercise test for measuring maximal oxygen uptake is unsuitable for screening tests in public heath examinations, because of the potential risks of exercise exertion and time demands. We designed this study to determine whether work-related physical activity is a potential predictor of maximal oxygen uptake, and to develop a maximal oxygen uptake equation using a non-exercise regression model for the cardiorespiratory fitness test in Korean adult workers. Study subjects were adult workers of small-sized companies in Korea. Subjects with history of disease such as hypertension, diabetes, asthma and angina were excluded. In total, 217 adult subjects (113 men of 21-55 years old and 104 women of 20-64 years old) were included. Self-report questionnaire survey was conducted on study subjects, and maximal oxygen uptake of each subject was measured with the exercise test. The statistical analysis was carried out to develop an equation for estimating maximal oxygen uptake. The predictors for estimating maximal oxygen uptake included age, gender, body mass index, smoking, leisure-time physical activity and the factors representing work-related physical activity. The work-related physical activity was identified to be a predictor of maximal oxygen uptake. Moreover, the equation showed high validity according to the statistical analysis. The equation for estimating maximal oxygen uptake developed in the present study could be used as a screening test for assessing cardiorespiratory fitness in Korean adult workers.

  19. Gain maximization in a probabilistic entanglement protocol

    Science.gov (United States)

    di Lorenzo, Antonio; Esteves de Queiroz, Johnny Hebert

    Entanglement is a resource. We can therefore define gain as a monotonic function of entanglement G (E) . If a pair with entanglement E is produced with probability P, the net gain is N = PG (E) - (1 - P) C , where C is the cost of a failed attempt. We study a protocol where a pair of quantum systems is produced in a maximally entangled state ρm with probability Pm, while it is produced in a partially entangled state ρp with the complementary probability 1 -Pm . We mix a fraction w of the partially entangled pairs with the maximally entangled ones, i.e. we take the state to be ρ = (ρm + wUlocρpUloc+) / (1 + w) , where Uloc is an appropriate unitary local operation designed to maximize the entanglement of ρ. This procedure on one hand reduces the entanglement E, and hence the gain, but on the other hand it increases the probability of success to P =Pm + w (1 -Pm) , therefore the net gain N may increase. There may be hence, a priori, an optimal value for w, the fraction of failed attempts that we mix in. We show that, in the hypothesis of a linear gain G (E) = E , even assuming a vanishing cost C -> 0 , the net gain N is increasing with w, therefore the best strategy is to always mix the partially entangled states.

    1982-01-01

    This article develops a strategy for maximizing percentage depletion deductions when extracting uranium or other solid minerals. The goal is to avoid losing percentage depletion deductions by staying below the 50% limitation on taxable income from the property. The article is divided into two major sections. The first section is comprised of depletion calculations that illustrate the problem and corresponding solutions. The last section deals with the feasibility of applying the strategy and complying with the Internal Revenue Code and appropriate regulations. Three separate strategies or appropriate situations are developed and illustrated. 13 references, 3 figures, 7 tables

  1. What currency do bumble bees maximize?

    Directory of Open Access Journals (Sweden)

    Nicholas L Charlton

    2010-08-01

    Full Text Available In modelling bumble bee foraging, net rate of energetic intake has been suggested as the appropriate currency. The foraging behaviour of honey bees is better predicted by using efficiency, the ratio of energetic gain to expenditure, as the currency. We re-analyse several studies of bumble bee foraging and show that efficiency is as good a currency as net rate in terms of predicting behaviour. We suggest that future studies of the foraging of bumble bees should be designed to distinguish between net rate and efficiency maximizing behaviour in an attempt to discover which is the more appropriate currency.

    We study four-dimensional N=1Spin(10) gauge theory with a single spinor and N Q vectors at the superconformal fixed point via the electric-magnetic duality and a-maximization. When gauge invariant chiral primary operators hit the unitarity bounds, we find that the theory with no superpotential is identical to the one with some superpotential at the infrared fixed point. The auxiliary field method in the electric theory offers a satisfying description of the infrared fixed point, which is consistent with the better picture in the magnetic theory. In particular, it gives a clear description of the emergence of new massless degrees of freedom in the electric theory

  5. Quantum effects in non-maximally symmetric spaces

    Shen, T.C.

    1985-01-01

    Non-Maximally symmetric spaces provide a more general background to explore the relation between the geometry of the manifold and the quantum fields defined in the manifold than those with maximally symmetric spaces. A static Taub universe is used to study the effect of curvature anisotropy on the spontaneous symmetry breaking of a self-interacting scalar field. The one-loop effective potential on a λphi 4 field with arbitrary coupling xi is computed by zeta function regularization. For massless minimal coupled scalar fields, first order phase transitions can occur. Keeping the shape invariant but decreasing the curvature radius of the universe induces symmetry breaking. If the curvature radius is held constant, increasing deformation can restore the symmetry. Studies on the higher-dimensional Kaluza-Klein theories are also focused on the deformation effect. Using the dimensional regularization, the effective potential of the free scalar fields in M 4 x T/sup N/ and M 4 x (Taub) 3 spaces are obtained. The stability criterions for the static solutions of the self-consistent Einstein equations are derived. Stable solutions of the M 4 x S/sup N/ topology do not exist. With the Taub space as the internal space, the gauge coupling constants of SU(2), and U(1) can be determined geometrically. The weak angle is therefore predicted by geometry in this model

    2013-01-01

    Full Text Available The iPad is a very popular touchscreen tablet computer, which was introduced approximately two, two and a half years ago. It runs the MAC operating system making it suitable for different general and special uses. The paper focuses on the fact how the use of iPads can help education, make teaching and learning more efficient. In addition to the technical, infrastructural parameters, which are essential as much as the user’s experience and it usability are concerned, the paper provides a few concrete applications as well. Today, the use of iPads is general either in everyday life, or in public education or tertiary education. The author analysis his experiences from the viewpoint of students, but also mentions applications useful for teachers. Students can use iPads with the appropriate applications in any stage of the learning process, e.g. using notes, course materials, schedules and assignments, cooperation, group assignments by collaboration. The paper also describes such solutions or respectively suggestions by means of which the monitoring of shared content and data can be realized by the teacher. A few professional applications (e.g. used by students of medicine, engineering and natural sciences are also listed.

    1998-01-01

    To examine the effects of a structured, time-limited parent training group on abusive or potentially abusive parents. A pretest-posttest control group design was used with consenting parents (N = 18) to examine the effects of Systematic Training for Effective Parenting (STEP) on abusive parents' perceptions of their children's behaviors and on the parents' potential to physically abuse. The Adlerian Parental Assessment of Child Behavior Scale and the Child Abuse Potential Inventory were used to measure treatment effects. After participating in STEP, abusive parents had significantly more positive perceptions of their children and were significantly less potentially abusive. Using volunteers, the project cost an average of $100 for each parent. The research lends empirical support to individual psychology and family systems theory. Future research is indicated using larger samples to examine lay vs. professional leadership of the groups, as well as comparisons of different parenting programs with abusive parents.

  9. Maximization techniques for oilfield development profits

    International Nuclear Information System (INIS)

    Lerche, I.

    1999-01-01

    In 1981 Nind provided a quantitative procedure for estimating the optimum number of development wells to emplace on an oilfield to maximize profit. Nind's treatment assumed that there was a steady selling price, that all wells were placed in production simultaneously, and that each well's production profile was identical and a simple exponential decline with time. This paper lifts these restrictions to allow for price fluctuations, variable with time emplacement of wells, and production rates that are more in line with actual production records than is a simple exponential decline curve. As a consequence, it is possible to design production rate strategies, correlated with price fluctuations, so as to maximize the present-day worth of a field. For price fluctuations that occur on a time-scale rapid compared to inflation rates it is appropriate to have production rates correlate directly with such price fluctuations. The same strategy does not apply for price fluctuations occurring on a time-scale long compared to inflation rates where, for small amplitudes in the price fluctuations, it is best to sell as much product as early as possible to overcome inflation factors, while for large amplitude fluctuations the best strategy is to sell product as early as possible but to do so mainly on price upswings. Examples are provided to show how these generalizations of Nind's (1981) formula change the complexion of oilfield development optimization. (author)

    2015-01-01

    Game-based learning (GBL) in medical education is emerging as a valid alternative to traditional teaching methods. Well-designed GBL sessions use non-threatening competition to capitalize on heightened learner arousal, allowing for high-level engagement and dynamic group discussion. While many templates for specific educational games have been published, little has been written on strategies for educators to create their own or how to use them with maximal effectiveness. These 12 tips provide specific recommendations for the successful design and implementation of GBL sessions in medical education based on a review of the literature and insight from experienced designers.

    Virtual Patients (VPs) have been used in undergraduate healthcare education for many years. This project is focused on using VPs for training professionals to care for highly vulnerable patient populations. The aim of the study was to evaluate if Refugee Trauma VPs was perceived as an effective and engaging learning tool by primary care professionals (PCPs) in a Primary Health Care Centre (PHC). A VP system was designed to create realistic and engaging VP cases for Refugee Trauma for training refugee patient interview, use of established trauma and mental health instruments as well as to give feedback to the learners. The patient interview section was based on video clips with a Bosnian actor with a trauma story and mental health problems. The video clips were recorded in Bosnian language to further increase the realism, but also subtitled in English. The system was evaluated by 11 volunteering primary health clinicians at the Lynn Community Health Centre, Lynn, Massachusetts, USA. The participants were invited to provide insights/feedback about the system's usefulness and educational value. A mixed methodological approach was used, generating both quantitative and qualitative data. Self-reported dimensions of clinical care, pre and post questionnaire questions on the PCPs clinical worldview, motivation to use the VP, and IT Proficiency. Construct items used in these questionnaires had previously demonstrated high face and construct validity. The participants ranked the mental status examination more positively after the simulation exercise compared to before the simulation. Follow up interviews supported the results. Even though virtual clinical encounters are quite a new paradigm in PHC, the participants in the present study considered our VP case to be a relevant and promising educational tool.

    Full Text Available Bangladesh Open University (BOU is the only public educational institution in Bangladesh, where, a dual-mode method of learning system has been introduced. Established in 21st October, 1992, the University now accommodates 1,74,459 learners in 2012. The wide range networking of this university provides it a great prospect to execute a broad spectrum of activities to accomplish its social responsibilities. Despite the aims of BOU at continuous quantitative improvement and greater equity in the society, like most of the ODL method universities in the world, BOU framed a limited objective to create awareness and preparedness about the contemporary global disaster proneness among its learners. Bangladesh for its geographical location, experiences several natural disasters like annual flood, heavy rainfall, cyclone and tidal surge, earth quake, river bank erosion, drought, etc. Lack of awareness of the sustainable use of the natural resources, and the consequences of the heedless consumption of them by the inhabitants enhanced the degree and frequency of these natural disasters during the last decades. The present study emphasizes on the role of Bangladesh Open University in creating awareness among its learners about the causes and pattern of disasters, pre and post disaster management strategies, etc. The study proves that BOU is a unique educational institution which, through the ODL method of teaching, using various educational medium like, tutorial support, printed study materials, electronic media, internet, and cellular phone, etc. can provided a wide range of knowledge about the disaster vulnerability, risk reduction and management strategies to its learners.

    With reference to the discussion about shareholder versus stakeholder maximization it is argued that the normal type of maximization is in fact stakeholder-owner maxi-mization. This means maximization of the sum of the value of the shares and stake-holder benefits belonging to the dominating...... including the shareholders of a company. Although it may be the ultimate goal for Corporate Social Responsibility to achieve this kind of maximization, broad stakeholder maximization is quite difficult to give a precise definition. There is no one-dimensional measure to add different stakeholder benefits...... not traded on the mar-ket, and therefore there is no possibility for practical application. Broad stakeholder maximization instead in practical applications becomes satisfying certain stakeholder demands, so that the practical application will be stakeholder-owner maximization un-der constraints defined...

    2016-08-01

    To describe the use of a low-pressure balloon inflation (LPBI) technique to delineate intraluminal plaque and guide directional atherectomy in order to maximize lumen gain and achieve procedure success. The technique is illustrated in a 77-year-old man with claudication who underwent superficial femoral artery revascularization using a HawkOne directional atherectomy catheter. A standard angioplasty balloon was inflated to 1 to 2 atm during live fluoroscopy to create a 3-dimensional "lumenogram" of the target lesion. Directional atherectomy was performed only where plaque impinged on the balloon at a specific fluoroscopic orientation. The results of the LPBI technique were corroborated with multimodality diagnostic imaging, including digital subtraction angiography, intravascular ultrasound, and intra-arterial pressure measurements. With the LPBI technique, directional atherectomy can routinely achieve <10% residual stenosis, as illustrated in this case, thereby broadly supporting a no-stent approach to lower extremity endovascular revascularization. © The Author(s) 2016.

    The Maximal Independent Set (MIS) graph problem arises in many applications such as computer vision, information theory, molecular biology, and process scheduling. The growing scale of MIS problems suggests the use of distributed-memory hardware as a cost-effective approach to providing necessary compute and memory resources. Luby proposed four randomized algorithms to solve the MIS problem. All those algorithms are designed focusing on shared-memory machines and are analyzed using the PRAM model. These algorithms do not have direct efficient distributed-memory implementations. In this paper, we extend two of Luby’s seminal MIS algorithms, “Luby(A)” and “Luby(B),” to distributed-memory execution, and we evaluate their performance. We compare our results with the “Filtered MIS” implementation in the Combinatorial BLAS library for two types of synthetic graph inputs.

    We investigate the quench dynamics of the one-particle entanglement spectra (OPES) for systems with topologically nontrivial phases. By using dimerized chains as an example, it is demonstrated that the evolution of OPES for the quenched bipartite systems is governed by an effective Hamiltonian which is characterized by a pseudospin in a time-dependent pseudomagnetic field S(k,t). The existence and evolution of the topological maximally entangled states (tMESs) are determined by the winding number of S(k,t) in the k-space. In particular, the tMESs survive only if nontrivial Berry phases are induced by the winding of S(k,t). In the infinite-time limit the equilibrium OPES can be determined by an effective time-independent pseudomagnetic field Seff(k). Furthermore, when tMESs are unstable, they are destroyed by quasiparticles within a characteristic timescale in proportion to the system size.

    , this article demonstrates that valuable lessons can be learned about policy learning, in practice and theoretically, by analysing the cooperation in the OMC committees. Using the Advocacy Coalition Framework as the starting point of analysis, 15 hypotheses on policy learning are tested. Among other things......In the voluminous literature on the European Union's open method of coordination (OMC), no one has hitherto analysed on the basis of scholarly examination the question of what contributes to the learning processes in the OMC committees. On the basis of a questionnaire sent to all participants......, it is concluded that in order to maximize policy learning in international committees, empirical data should be made available to committees and provided by sources close to the participants (i.e. the Commission). In addition, the work in the committees should be made prestigious in order to attract well...

    We investigate some properties of n( {>=} 4)-dimensional spacetimes having symmetries corresponding to the isometries of an (n - 2)-dimensional maximally symmetric space in Lovelock gravity under the null or dominant energy condition. The well-posedness of the generalized Misner-Sharp quasi-local mass proposed in the past study is shown. Using this quasi-local mass, we clarify the basic properties of the dynamical black holes defined by a future outer trapping horizon under certain assumptions on the Lovelock coupling constants. The C{sup 2} vacuum solutions are classified into four types: (i) Schwarzschild-Tangherlini-type solution; (ii) Nariai-type solution; (iii) special degenerate vacuum solution; and (iv) exceptional vacuum solution. The conditions for the realization of the last two solutions are clarified. The Schwarzschild-Tangherlini-type solution is studied in detail. We prove the first law of black-hole thermodynamics and present the expressions for the heat capacity and the free energy.

    Waves propagating through a bounded plasma can rearrange the densities of states in the six-dimensional velocity-configuration phase space. Depending on the rearrangement, the wave energy can either increase or decrease, with the difference taken up by the total plasma energy. In the case where the rearrangement is diffusive, only certain plasma states can be reached. It turns out that the set of reachable states through such diffusive rearrangements has been described in very different contexts. Building upon those descriptions, and making use of the fact that the plasma energy is a linear functional of the state densities, the maximal extractable energy under diffusive rearrangement can then be addressed through linear programming.

    This paper describes the strategies employed to increase the profitability of an existing ambulatory pharmacy operated by the hospital. Methods to generate new revenue including implementation of a home parenteral therapy program, a home enteral therapy program, a durable medical equipment service, and home care disposable sales are described. Programs to maximize existing revenue sources such as increasing the capture rate on discharge prescriptions, increasing "walk-in" prescription traffic and increasing HMO prescription volumes are discussed. A method utilized to reduce drug expenditures is also presented. By minimizing expenses and increasing the revenues for the ambulatory pharmacy operation, net profit increased from +26,000 to over +140,000 in one year.

    The use of dewatering systems in the mining, industrial sludge and sewage waste treatment industries is discussed, also describing some of the problems that have been encountered while using drilling fluid dewatering technology. The technology is an acceptable drilling waste handling alternative but it has had problems associated with recycled fluid incompatibility, high chemical costs and system inefficiencies. This paper discussed the following five action areas that can maximize the benefits and help reduce costs of a dewatering project: (1) co-ordinate all services, (2) choose equipment that fits the drilling program, (3) match the chemical treatment with the drilling fluid types, (4) determine recycled fluid compatibility requirements, and (5) determine the disposal requirements before project start-up. 2 refs., 5 figs

    We study the conditions when mixtures of maximally entangled pure states remain entangled. We found that the resulting mixed state remains entangled when the number of entangled pure states to be mixed is less than or equal to the dimension of the pure states. For the latter case of mixing a number of pure states equal to their dimension, we found that the mixed state is entangled provided that the entangled pure states to be mixed are not equally weighted. We also found that one can restrict the set of pure states that one can mix from in order to ensure that the resulting mixed state is genuinely entangled. Also, we demonstrate how these results could be applied as a way to detect entanglement in mixtures of the entangled pure states with noise.

  12. Maximally reliable Markov chains under energy constraints.

    Signal-to-noise ratios in physical systems can be significantly degraded if the outputs of the systems are highly variable. Biological processes for which highly stereotyped signal generations are necessary features appear to have reduced their signal variabilities by employing multiple processing steps. To better understand why this multistep cascade structure might be desirable, we prove that the reliability of a signal generated by a multistate system with no memory (i.e., a Markov chain) is maximal if and only if the system topology is such that the process steps irreversibly through each state, with transition rates chosen such that an equal fraction of the total signal is generated in each state. Furthermore, our result indicates that by increasing the number of states, it is possible to arbitrarily increase the reliability of the system. In a physical system, however, an energy cost is associated with maintaining irreversible transitions, and this cost increases with the number of such transitions (i.e., the number of states). Thus, an infinite-length chain, which would be perfectly reliable, is infeasible. To model the effects of energy demands on the maximally reliable solution, we numerically optimize the topology under two distinct energy functions that penalize either irreversible transitions or incommunicability between states, respectively. In both cases, the solutions are essentially irreversible linear chains, but with upper bounds on the number of states set by the amount of available energy. We therefore conclude that a physical system for which signal reliability is important should employ a linear architecture, with the number of states (and thus the reliability) determined by the intrinsic energy constraints of the system.

    With introduction of the new Federal Medical Licensing Regulations (Approbationsordnung) in Germany, integrated teaching in "Rehabilitation, Physical Medicine, Naturopathic Treatment" (Querschnittsbereich Q12) has become obligatory for the first time. Furthermore, the new Regulations require the medical faculties in Germany to realize an innovative didactic orientation in teaching. This paper provides an overview of recent applications of teaching techniques and examination methods in medical education with special consideration of the new integrated course Q12 and further teaching methods related to rehabilitative issues. Problem-oriented learning (POL), problem-based learning (PBL), bedside teaching, eLearning, and the examination methods Objective Structured Clinical Examination (OSCE) and Triple Jump are in the focus. This overview is intended as the basis for subsequent publications of the Commission for Undergraduate and Postgraduate Training of the German Society of Rehabilitation Science (DGRW), which will present examples of innovative teaching material.

    2015-07-01

    Supplemental Instruction (SI) is a programme that is attached to difficult courses with the objective of increasing student performance and retention. However, an SI programme also has the potential to increase overall student performance and retention during the first critical year if applied to introductory courses. In this study the latter objective is investigated in an engineering educational environment. The study shows that an SI programme attached to difficult first semester courses for new engineering students has substantial positive effects on both first-year student performance and retention. Both male and female students appear to benefit from attending SI to the same extent. Some potential reasons for these improved first-year student performances are that attendance at SI sessions appears to lead to improved self-confidence, a broader network of study partners, improved study strategies and problem-solving skills and an increased ability to critically review material and work with others.

  18. The Disproportionate and Potentially Negative Influence of Research Universities on the Quality of Geoscience Education

    2010-12-01

    There is a large and growing body of research indicating that post-secondary education in science, technology, engineering, and mathematics (STEM) fields is failing to prepare citizens for the 21st century economy. Introductory STEM courses are vital for preparing science majors for their fields of study and are the only exposure to science many college students will receive, but the quality of teaching in these courses is often not informed by research on teaching and learning. Research universities play an especially prominent role in the design of introductory courses. While research and doctoral universities account for only about 6% of all higher education institutions, they confer 32 per cent of the baccalaureate degrees, and 56 per cent of the baccalaureates earned by recent recipients of science and engineering doctorates. By assuming that larger introductory classes occur at research institutions one can estimate that a dominant number of students receiving introductory instruction in the geosciences are probably occurring at research institutions. Moreover, research universities produce the majority of tenure-track faculty who will later teach at four-year colleges, so the role of research institutions in the influence of introductory course design is expected to be disproportionately large. While introductory courses at research universities play a influential role in how such courses are designed, the teaching of introductory courses is too often viewed as an undesirable assignment for instructors at those institutions. The effort seems unrewarding with incentives for improving teaching at research institutions perceived as modest at best, if not negative. It is commonly perceived that teaching introductory courses will decrease opportunities for teaching higher-level courses to graduate students and/or to conduct research. Furthermore, even for those interested in improving their pedagogical methods, current approaches to professional development are

    Existence of maximal and 'almost maximal' hypersurfaces in asymptotically flat space-times is established under boundary conditions weaker than those considered previously. We show in particular that every vacuum evolution of asymptotically flat data for Einstein equations can be foliated by slices maximal outside a spatially compact set and that every (strictly) stationary asymptotically flat space-time can be foliated by maximal hypersurfaces. Amongst other uniqueness results, we show that maximal hypersurface can be used to 'partially fix' an asymptotic Poincare group. (orig.)

    Can stories succeed where traditional forms of diplomacy have faltered? This study examined whether a primetime drama could impact American viewers’ knowledge, attitudes, and behavior with respect to U.S. foreign policy and funding by surveying 173 viewers of an episode of Law & Order: SVU (“Witness”). Additionally, this study sought to uncover which theoretical construct — involvement with a specific character or involvement with the narrative more generally (transportation) — best predicted impact. The fictional character in question was Nardelie, a woman forced to flee the Democratic Republic of the Congo after repeated rape by militias vying for “conflict minerals,” so named because control of these valuable minerals has triggered numerous conflicts. Separate regression analyses suggested a positive relationship between impact of the storyline and both theoretical constructs. However, when both constructs were entered into a single regression, involvement with Nardelie was the stronger predictor of knowledge (e.g., conflict minerals, sexual violence, and asylum issues) and current or future behavior (i.e., discussing global health) while transportation was the stronger predictor of attitudes (i.e., support for aid). This suggests that, while correlated, these constructs do not completely overlap. Implications of these results and the use of entertainment education in public diplomacy are discussed.

    2011-03-01

    The major focus of this ethnographic study is devoted to exploring the confluence of global and local referents of science education in the context of an urban chemistry laboratory classroom taught by a first-generation Filipino-American male teacher. This study investigates encounters between the teacher and four second-generation immigrant female students of color, as well as encounters among the four students. The pervasive spread of neoliberal ideology of accountability and sanctions both globally and locally, particularly in public high schools in the Bronx, New York City fuel situations for teaching and learning science that are encoded with the referents of top-down control. In the face of theses challenges, classroom participants must become aware of productive ways to build solidarity and interstitial culture across salient social boundaries, such as age, gender, ethnicity and role, to create and sustain successful teaching and learning of chemistry. Empirical evidence for solidarity was guided by physical and verbal displays of synchrony, mutual focus, entrainment, and emotional energy, body gestures, and prosody markers. This study shows that classroom participants used a combination of prosody markers to appropriate resources to decrease breaches in face-to-face encounters and, at the same time, create and sustain participation and solidarity to successfully complete an acid-base experiment.

    Abstract Background: Previous research has paid little to no attention towards exploring methods of identifying existing medical student leaders. Aim: Focusing on the role of influence and employing the tenets of the engaging leadership model, this study examines demographic and academic performance-related differences of positive influencers and if students who have been peer-identified as positive influencers also demonstrate high levels of genuine concern for others. Methods: Three separate fourth-year classes were asked to designate classmates that had significant positive influences on their professional and personal development. The top 10% of those students receiving positive influence nominations were compared with the other students on demographics, academic performance, and genuine concern for others. Results: Besides age, no demographic differences were found between positive influencers and other students. High positive influencers were not found to have higher standardized exam scores but did receive significantly higher clinical clerkship ratings. High positive influencers were found to possess a higher degree of genuine concern for others. Conclusion: The findings lend support to (a) utilizing the engaging model to explore leaders and leadership within medical education, (b) this particular method of identifying existing medical student leaders, and (c) return the focus of leadership research to the power of influence.

    African-American (AA) men have higher arterial stiffness and augmentation index (AIx) than Caucasian-American (CA) men. Women have greater age-associated increases in arterial stiffness and AIx than men. This study examined racial and sex differences in arterial stiffness and central hemodynamics at rest and after an acute bout of maximal exercise in young healthy individuals. One hundred young, healthy individuals (28 AA men, 24 AA women, 25 CA men, and 23 CA women) underwent measurements of aortic blood pressure (BP) and arterial stiffness at rest and 15 and 30 min after an acute bout of graded maximal aerobic exercise. Aortic BP and AIx were derived from radial artery applanation tonometry. Aortic stiffness (carotid-femoral) was measured via pulse wave velocity. Aortic stiffness was increased in AA subjects but not in CA subjects (P < 0.05) after an acute bout of maximal cycling exercise, after controlling for body mass index. Aortic BP decreased after exercise in CA subjects but not in AA subjects (P < 0.05). Women exhibited greater reductions in AIx after maximal aerobic exercise compared with men (P < 0.05). In conclusion, race and sex impact vascular and central hemodynamic responses to exercise. Young AA and CA subjects exhibited differential responses in central stiffness and central BP after acute maximal exercise. Premenopausal women had greater augmented pressure at rest and after maximal aerobic exercise than men. Future research is needed to examine the potential mechanisms.

    2014-03-01

    In recent years, opportunities for postgraduate university education in implant dentistry have increased significantly, with an increase in both the number but also the complexity of available postgraduate programmes. However, there appears to be a lack of standards directing the learning outcomes of such programmes. A scientific literature search was conducted for publications reporting on university programmes within implant dentistry, including description of programmes and evaluation of learning outcomes. A separate Internet search was conducted to collect information on existing university programmes as presented on university websites. Implant dentistry has reached a critical mass of an independent, multidisciplinary and vibrant domain of science, which combines knowledge and discovery from many clinical and basic sciences. Many university programmes conclude with a master's or equivalent degree, but there appears to be a great diversity with regard to duration and learning objectives, as well as targeted skills and competences. The importance of implant dentistry has also increased within established specialist training programmes. There was little indication, however, that the comprehensive aspects of implant dentistry are present in all specialist training programmes where implants are being covered. Although universities should maintain the options of designing academic programmes as they best see fit, it is imperative for them to introduce some form of transparent and comparable criteria, which will allow the profession and the public to relate the degree and academic credentials to the actual skills and competences of the degree holder. With regard to established specialist training programmes, the interdisciplinary and comprehensive nature of implant dentistry needs to be emphasised, covering both surgical and restorative aspects. Finally, implant dentistry is not, at present, a dental specialty. The profession has not reached a consensus as to whether

  8. A Note of Caution on Maximizing Entropy

    Directory of Open Access Journals (Sweden)

    Richard E. Neapolitan

    2014-07-01

    Full Text Available The Principle of Maximum Entropy is often used to update probabilities due to evidence instead of performing Bayesian updating using Bayes’ Theorem, and its use often has efficacious results. However, in some circumstances the results seem unacceptable and unintuitive. This paper discusses some of these cases, and discusses how to identify some of the situations in which this principle should not be used. The paper starts by reviewing three approaches to probability, namely the classical approach, the limiting frequency approach, and the Bayesian approach. It then introduces maximum entropy and shows its relationship to the three approaches. Next, through examples, it shows that maximizing entropy sometimes can stand in direct opposition to Bayesian updating based on reasonable prior beliefs. The paper concludes that if we take the Bayesian approach that probability is about reasonable belief based on all available information, then we can resolve the conflict between the maximum entropy approach and the Bayesian approach that is demonstrated in the examples.

    It has been widely demonstrated that the structure of a network is a major factor that affects its traffic dynamics. In this work, we try to identify the optimal topologies for maximizing the network transmission capacity, as well as to build a clear relationship between structural features of a network and the transmission performance in terms of traffic delivery. We propose an approach for designing optimal network topologies against traffic congestion by link rewiring and apply them on the Barabási-Albert scale-free, static scale-free and Internet Autonomous System-level networks. Furthermore, we analyze the optimized networks using complex network parameters that characterize the structure of networks, and our simulation results suggest that an optimal network for traffic transmission is more likely to have a core-periphery structure. However, assortative mixing and the rich-club phenomenon may have negative impacts on network performance. Based on the observations of the optimized networks, we propose an efficient method to improve the transmission capacity of large-scale networks.

  10. When Wanting the Best Goes Right or Wrong: Distinguishing Between Adaptive and Maladaptive Maximization.

    Researchers have often disagreed on how to define maximization, leading to conflicting conclusions about its potential benefits or drawbacks. Drawing from motivation research, we distinguish between the goals (i.e., wanting the best) and strategies (e.g., alternative search) associated with maximizing. Three studies illustrate how this differentiation offers insight into when maximizers do or do not experience affective costs when making decisions. In Study 1, we show that two motivational orientations, promotion focus and assessment mode, are both associated with the goal of wanting the best, yet assessment (not promotion) is related to the use of alternative search strategies. In Study 2, we demonstrate that alternative search strategies are associated with frustration on a discrete decision task. In Study 3, we provide evidence that one reason for this link may be due to reconsideration of previously dismissed options. We discuss the potential of this approach to integrate research in this area.

    2010-01-01

    Full Text Available A review of historical data for Hawaii reveals that significant tsunamis have been reported for only four of twenty-six potentially tsunamigenic earthquakes from 1868 through 2009 with magnitudes of 6.0 or greater. During the same time period, three significant tsunamis have been reported for substantially smaller earthquakes. This historical perspective, the fact that the last significant local tsunami occurred in 1975, and an understandable preoccupation with tsunamis generated around the margins of the Pacific, all combine to suggest apparent deficiencies in: (1 personal awareness of what to do in the event of a possible local tsunami; (2 the distribution of instrumentation capable of providing rapid confirmation that a local tsunami has been generated; and (3 the subsequent issuance of timely warnings for local tsunamis. With these deficiencies, far more lives may be lost in Hawaii due to local tsunamis than will result from tsunamis that have originated along the margins of the Pacific. Similar deficiencies may exist in other areas of the world threatened by local tsunamis.

    2014-07-01

    Full Text Available A module for fast determination of reduction potentials, E°, of redox-active proteins has been implemented in the CHARMM INterface and Graphics (CHARMMing web portal (www.charmming.org. The free energy of reduction, which is proportional to E°, is composed of an intrinsic contribution due to the redox site and an environmental contribution due to the protein and solvent. Here, the intrinsic contribution is selected from a library of pre-calculated density functional theory values for each type of redox site and redox couple, while the environmental contribution is calculated from a crystal structure of the protein using Poisson-Boltzmann continuum electrostatics. An accompanying lesson demonstrates a calculation of E°. In this lesson, an ionizable residue in a [4Fe-4S]-protein that causes a pH-dependent E° is identified, and the E° of a mutant that would test the identification is predicted. This demonstration is valuable to both computational chemistry students and researchers interested in predicting sequence determinants of E° for mutagenesis.

    Suicide rates are higher among U.S. physicians than the general population. Untreated depression is a major risk factor, yet depression stigma presents a barrier to treatment. This study aims to identify early career indications of stigma among physicians-in-training and to inform the design of stigma-reduction programs. A cross-sectional student survey administered at a large, Midwestern medical school in fall 2009 included measures of depression symptoms, attitudes toward mental health, and potential sources of depression stigma. Principal components factor analysis and linear regression were used to examine stigma factors associated with depression in medical students. The response rate was 65.7%, with 14.7% students reporting a previous depression diagnosis. Most students indicated that, if depressed, they would feel embarrassed if classmates knew. Many believed that revealing depression could negatively affect professional advancement. Factor analyses revealed three underlying stigma constructs: personal weakness, public devaluation, and social/professional discrimination. Students associating personal weakness with depression perceived medication as less efficacious and the academic environment as more competitive. Those endorsing public stigma viewed medication and counseling as less efficacious and associated depression with an inability to cope. Race, gender, and diagnosis of past/current depression also related to beliefs about stigma. Depression measures most strongly predicted stigma associated with personal weakness and social/professional discrimination. Recommendations for decreasing stigma among physicians-in-training include consideration of workplace perceptions, depression etiology, treatment efficacy, and personal attributes in the design of stigma reduction programs that could facilitate help-seeking behavior among physicians throughout their career.

    Poster presentations are an important part of presenting scientific techniques and represent an integral part of conferences and meetings. Traditionally, paper format is used; however, in recent years electronic posters and other methods, such as incorporating a DVD player as part of a poster, have been successfully used. We describe and demonstrate the use of an augmented reality application for smartphones and tablets as a potential future addition to the presentation of scientific work and surgical techniques in poster format. This method allows the audience to view surgical techniques and research as 3D animation or video by using a trigger image in a poster/journal/text book via their smart device. The author used the free Aurasma© application available on both iOS and Android 2.2 and higher platforms from iTunes App Store and Google Play. Once installed, any user with a 3G or WiFi connection via a smart phone or tablet can subscribe to the Medical Illustration channel for free. The user can then scan the trigger image placed on a poster with a mobile device to view videos, animations or 3D data. Further interaction can direct the user to a website for more content. The author has trialled this method at a regional burns and plastic surgery centre and found it to be highly effective. The use of this novel method adds a new dimension to the presentation of scientific work at surgical and medical conferences and as part of journals and textbooks by permitting users to view scientific data and techniques on mobile devices as videos or as three dimensional environments at their own leisure.

  17. Value maximizing maintenance policies under general repair

    International Nuclear Information System (INIS)

    Marais, Karen B.

    2013-01-01

    One class of maintenance optimization problems considers the notion of general repair maintenance policies where systems are repaired or replaced on failure. In each case the optimality is based on minimizing the total maintenance cost of the system. These cost-centric optimizations ignore the value dimension of maintenance and can lead to maintenance strategies that do not maximize system value. This paper applies these ideas to the general repair optimization problem using a semi-Markov decision process, discounted cash flow techniques, and dynamic programming to identify the value-optimal actions for any given time and system condition. The impact of several parameters on maintenance strategy, such as operating cost and revenue, system failure characteristics, repair and replacement costs, and the planning time horizon, is explored. This approach provides a quantitative basis on which to base maintenance strategy decisions that contribute to system value. These decisions are different from those suggested by traditional cost-based approaches. The results show (1) how the optimal action for a given time and condition changes as replacement and repair costs change, and identifies the point at which these costs become too high for profitable system operation; (2) that for shorter planning horizons it is better to repair, since there is no time to reap the benefits of increased operating profit and reliability; (3) how the value-optimal maintenance policy is affected by the system's failure characteristics, and hence whether it is worthwhile to invest in higher reliability; and (4) the impact of the repair level on the optimal maintenance policy. -- Highlights: •Provides a quantitative basis for maintenance strategy decisions that contribute to system value. •Shows how the optimal action for a given condition changes as replacement and repair costs change. •Shows how the optimal policy is affected by the system's failure characteristics. •Shows when it is

    This study sought to gain insight into blended learning-naive sports science students' understanding and perceptions of the potential benefits and limitations of blended (hybrid) learning, which has been defined as the thoughtful integration of face-to-face and online instructional approaches. Five focus groups, each comprising 3-4 students from either the undergraduate or postgraduate sports science programmes were conducted. The focus groups were facilitated by a researcher who was not involved in sports science. Audio recordings of the focus groups were transcribed verbatim. NVivo software was used to code the transcripts to identify the themes and subthemes. Students generally had little initial understanding of blended learning. When provided with a definition, they believed that blended learning could improve educational outcomes and assist those who were legitimately unable to attend a session. Their reservations about blended learning mainly related to some students not being sufficiently autonomous to undertake independent study, timetabling considerations and access to reliable Internet services. For blended learning to be effective, students felt the online material had to be interactive, engaging and complement the face-to-face sessions. Better understanding the perceptions of the students in the current study may assist educators who are considering implementing blended learning in their teaching.

    The purpose of this study was to explore the use of cognitive task analysis to inform the teaching of psychomotor skills and cognitive strategies in clinical tasks in dental education. Methods used were observing and videotaping an expert at one dental school thinking aloud while performing a specific preclinical task (in a simulated environment), interviewing the expert to probe deeper into his thinking processes, and applying the same procedures to analyze the performance of three second-year dental students who had recently learned the analyzed task and who represented a spectrum of their cohort's ability to undertake the procedure. The investigators sought to understand how experts (clinical educators) and intermediates (trained students) overlapped and differed at points in the procedure that represented the highest cognitive load, known as "critical incidents." Findings from this study and previous research identified possible limitations of current clinical teaching as a result of expert blind spots. These findings coupled with the growing evidence of the effectiveness of peer teaching suggest the potential role of intermediates in helping novices learn preclinical dentistry tasks.

    Despite strong support for inclusive education in principle, many teachers and administrators still demonstrate mixed responses to the inclusion of certain students in their classrooms. Students with specific learning difficulties (SpLD) form a large group of students in inclusive classrooms yet some provincial, state and national jurisdictions fail to acknowledge the existence of these students. Not acknowledging and understanding these students can deny them the recognition and resources necessary for their genuine participation in education and, in turn, society. The aim of this study was to examine British in-service secondary teachers' attributional responses to students with and without specific learning difficulties. The participants included 122 British secondary school teachers who were surveyed in response to vignettes of hypothetical male students who had failed a class test. The study found that while teachers attributed more positive causes towards students without SpLD, they exhibited more negative causes towards students with SpLD. Teachers' causal attributional outcomes of students' level of achievement can impact upon the students' own attributions, with teachers' responses for students with SpLD having the potential to, unintentionally, influence students' own sense of self-efficacy and motivation. The paper concludes with a consideration of the implications of the research and recommendations for practice.

  1. Applying the Trigger Review Method after a brief educational intervention: potential for teaching and improving safety in GP specialty training?

    The Trigger Review Method (TRM) is a structured approach to screening clinical records for undetected patient safety incidents (PSIs) and identifying learning and improvement opportunities. In Scotland, TRM participation can inform GP appraisal and has been included as a core component of the national primary care patient safety programme that was launched in March 2013. However, the clinical workforce needs up-skilled and the potential of TRM in GP training has yet to be tested. Current TRM training utilizes a workplace face-to-face session by a GP expert, which is not feasible. A less costly, more sustainable educational intervention is necessary to build capability at scale. We aimed to determine the feasibility and impact of TRM and a related training intervention in GP training. We recruited 25 west of Scotland GP trainees to attend a 2-hour TRM workshop. Trainees then applied TRM to 25 clinical records and returned findings within 4-weeks. A follow-up feedback workshop was held. 21/25 trainees (84%) completed the task. 520 records yielded 80 undetected PSIs (15.4%). 36/80 were judged potentially preventable (45%) with 35/80 classified as causing moderate to severe harm (44%). Trainees described a range of potential learning and improvement plans. Training was positively received and appeared to be successful given these findings. TRM was valued as a safety improvement tool by most participants. This small study provides further evidence of TRM utility and how to teach it pragmatically. TRM is of potential value in GP patient safety curriculum delivery and preparing trainees for future safety improvement expectations.

  4. Maximizing Statistical Power When Verifying Probabilistic Forecasts of Hydrometeorological Events

    DeChant, C. M.; Moradkhani, H.

    2014-12-01

    Hydrometeorological events (i.e. floods, droughts, precipitation) are increasingly being forecasted probabilistically, owing to the uncertainties in the underlying causes of the phenomenon. In these forecasts, the probability of the event, over some lead time, is estimated based on some model simulations or predictive indicators. By issuing probabilistic forecasts, agencies may communicate the uncertainty in the event occurring. Assuming that the assigned probability of the event is correct, which is referred to as a reliable forecast, the end user may perform some risk management based on the potential damages resulting from the event. Alternatively, an unreliable forecast may give false impressions of the actual risk, leading to improper decision making when protecting resources from extreme events. Due to this requisite for reliable forecasts to perform effective risk management, this study takes a renewed look at reliability assessment in event forecasts. Illustrative experiments will be presented, showing deficiencies in the commonly available approaches (Brier Score, Reliability Diagram). Overall, it is shown that the conventional reliability assessment techniques do not maximize the ability to distinguish between a reliable and unreliable forecast. In this regard, a theoretical formulation of the probabilistic event forecast verification framework will be presented. From this analysis, hypothesis testing with the Poisson-Binomial distribution is the most exact model available for the verification framework, and therefore maximizes one's ability to distinguish between a reliable and unreliable forecast. Application of this verification system was also examined within a real forecasting case study, highlighting the additional statistical power provided with the use of the Poisson-Binomial distribution.

    The aim of the present study was to evaluate the antiproliferative effect of phenylpropanoids isolated from the n-BuOH-soluble fraction of an ethanolic extract of Lagotis brevituba Maxim. The phenylpropanoids were identified as echinacoside, lagotioside, glucopyranosyl(1-6)martynoside, plantamoside, and verbascoside. Three of the compounds, lagotioside, glucopyranosyl(1-6)martynoside, and plantamoside, were isolated from L. brevituba for the first time. The antiproliferative activity of the isolates was evaluated in human gastric carcinoma (MGC-803), human colorectal carcinoma (HCT116), human hepatocellar carcinoma (HepG2), and human lung cancer (HCT116) cells using an 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Plantamoside showed promising activity against MGC-803 cells, with a half maximal inhibitory concentration value of 37.09 μM. The mechanism of the pro-apoptosis effect of plantamoside was then evaluated in MGC-803 cells. Changes in cell morphology, including disorganization of the architecture of actin microfilaments and formation of apoptotic bodies, together with cell cycle arrest in G2/M phases, were observed after treatment of plantamoside. The antiproliferative and pro-apoptotic effects were associated with a decrease in the ratio of Bcl-2/Bax and reduced mitochondrial membrane potential, which was accompanied by the release of reactive oxygen species and Ca 2+ into the cytoplasm. Taken together, the results indicated that plantamoside promotes apoptosis via a mitochondria-dependent mechanism. Copyright © 2017 John Wiley & Sons, Ltd. Copyright © 2017 John Wiley & Sons, Ltd.

    Our previous research suggests that people reporting a stronger desire to maximize obtain worse life outcomes (Bruine de Bruin et al., 2007). Here, we examine whether this finding may be explained by the decision-making styles of self-reported maximizers. Expanding on Schwartz et al.\\ (2002), we find that self-reported maximizers are more likely to show problematic decision-making styles, as evidenced by self-reports of less behavioral coping, greater dependence on others when making decision...

    1999-01-01

    The naturalness of maximal mixing between myon- and tau-neutrinos is investigated. A spontaneously broken nonabelian generation symmetry can explain a small parameter which governs the deviation from maximal mixing. In many cases all three neutrino masses are almost degenerate. Maximal ν μ -ν τ -mixing suggests that the leading contribution to the light neutrino masses arises from the expectation value of a heavy weak triplet rather than from the seesaw mechanism. In this scenario the deviation from maximal mixing is predicted to be less than about 1%. (Copyright (c) 1999 Elsevier Science B.V., Amsterdam. All rights reserved.)

    We propose a generalized entropy maximization procedure, which takes into account the generalized averaging procedures and information gain definitions underlying the generalized entropies. This novel generalized procedure is then applied to Renyi and Tsallis entropies. The generalized entropy maximization procedure for Renyi entropies results in the exponential stationary distribution asymptotically for q element of (0,1] in contrast to the stationary distribution of the inverse power law obtained through the ordinary entropy maximization procedure. Another result of the generalized entropy maximization procedure is that one can naturally obtain all the possible stationary distributions associated with the Tsallis entropies by employing either ordinary or q-generalized Fourier transforms in the averaging procedure.

    This study aimed to evaluate the anti-hyperglycemic effect of ethanol extract from Actinidia kolomikta (Maxim. etRur.) Maxim. root (AKE).An in vitro evaluation was performed by using rat intestinal α-glucosidase (maltase and sucrase), the key enzymes linked with type 2 diabetes. And an in vivo evaluation was also performed by loading maltose, sucrose, glucose to normal rats. As a result, AKE showed concentration-dependent inhibition effects on rat intestinal maltase and rat intestinal sucrase with IC(50) values of 1.83 and 1.03mg/mL, respectively. In normal rats, after loaded with maltose, sucrose and glucose, administration of AKE significantly reduced postprandial hyperglycemia, which is similar to acarbose used as an anti-diabetic drug. High contents of total phenolics (80.49 ± 0.05mg GAE/g extract) and total flavonoids (430.69 ± 0.91mg RE/g extract) were detected in AKE. In conclusion, AKE possessed anti-hyperglycemic effects and the possible mechanisms were associated with its inhibition on α-glucosidase and the improvement on insulin release and/or insulin sensitivity as well. The anti-hyperglycemic activity possessed by AKE maybe attributable to its high contents of phenolic and flavonoid compounds.

  15. Alternative approaches to maximally supersymmetric field theories

    International Nuclear Information System (INIS)

    Broedel, Johannes

    2010-01-01

    The central objective of this work is the exploration and application of alternative possibilities to describe maximally supersymmetric field theories in four dimensions: N=4 super Yang-Mills theory and N=8 supergravity. While twistor string theory has been proven very useful in the context of N=4 SYM, no analogous formulation for N=8 supergravity is available. In addition to the part describing N=4 SYM theory, twistor string theory contains vertex operators corresponding to the states of N=4 conformal supergravity. Those vertex operators have to be altered in order to describe (non-conformal) Einstein supergravity. A modified version of the known open twistor string theory, including a term which breaks the conformal symmetry for the gravitational vertex operators, has been proposed recently. In a first part of the thesis structural aspects and consistency of the modified theory are discussed. Unfortunately, the majority of amplitudes can not be constructed, which can be traced back to the fact that the dimension of the moduli space of algebraic curves in twistor space is reduced in an inconsistent manner. The issue of a possible finiteness of N=8 supergravity is closely related to the question of the existence of valid counterterms in the perturbation expansion of the theory. In particular, the coefficient in front of the so-called R 4 counterterm candidate has been shown to vanish by explicit calculation. This behavior points into the direction of a symmetry not taken into account, for which the hidden on-shell E 7(7) symmetry is the prime candidate. The validity of the so-called double-soft scalar limit relation is a necessary condition for a theory exhibiting E 7(7) symmetry. By calculating the double-soft scalar limit for amplitudes derived from an N=8 supergravity action modified by an additional R 4 counterterm, one can test for possible constraints originating in the E 7(7) symmetry. In a second part of the thesis, the appropriate amplitudes are calculated

These values are optimized along a nominal trajectory in order to maximize probability of mission success, and reducing the probability of false positives (defined as when the INS would report a second fault condition resulting in loss of mission, but the vehicle would still meet insertion requirements within system-level margins). This paper will describe an optimization approach using Genetic Algorithms to tune the threshold parameters to maximize vehicle resilience to second fault events as a function of potential fault magnitude and time of fault over an ascent mission profile. The analysis approach, and performance assessment of the results will be presented to demonstrate the applicability of this process to second fault detection to maximize mission probability of success.

Lastly, professional associations that represent TV weathercasters (AMS and NWA), and government agencies that produce climate and weather data for meteorologists (NOAA and NASA), are committed to help scale up this model so that all interested TV weathercasters have easy access to localized information through which to educate their viewers about local weather and related implications of climate change. In sum, by engaging and empowering TV weathercasters as climate educators, we seek to increase public understanding of the relationships among climate, climate variability, climate change, weather extremes and community vulnerability, and we believe this model has considerable potential.

  18. Kinetic theory in maximal-acceleration invariant phase space

    1989-01-01

    A vanishing directional derivative of a scalar field along particle trajectories in maximal acceleration invariant phase space is identical in form to the ordinary covariant Vlasov equation in curved spacetime in the presence of both gravitational and nongravitational forces. A natural foundation is thereby provided for a covariant kinetic theory of particles in maximal-acceleration invariant phase space. (orig.)

    We show that all IIB supergravity backgrounds which admit more than 28 Killing spinors are maximally supersymmetric. In particular, we find that for all N>28 backgrounds the supercovariant curvature vanishes, and that the quotients of maximally supersymmetric backgrounds either preserve all 32 or N<29 supersymmetries

    Full Text Available Learning a new language is ultimately to be able to communicate with it. Encouraging a sense of responsibility on the part of the learners is crucial for training them to be proficient communicators. As such, understanding the strategies that they employ in acquiring the language skill is important to come to ideas of how to promote learner autonomy. Research recently conducted with three different groups of learners of English at the tertiary education level in Malang indicated that they used metacognitive and social startegies at a high frequency, while memory, cognitive, conpensation, and affective strategies were exercised at a medium frewuency. This finding implies that the learners have acquired some degrees of autonomy because metacognive strategies requires them to independently make plans for their learning activities as well as evaluate the progress, and social strategies requires them to independently enhance communicative interactions with other people. Further actions are then to be taken increase their learning autonomy, that is by intensifying the practice of use of the other four strategy categories, which are not yet applied intensively.

  10. Renewable Substitutability Index: Maximizing Renewable Resource Use in Buildings

    Directory of Open Access Journals (Sweden)

    Ravi S. Srinivasan

    2015-05-01

    Full Text Available In order to achieve a material and energy balance in buildings that is sustainable in the long run, there is an urgent need to assess the renewable and non-renewable resources used in the manufacturing process and to progressively replace non-renewable resources with renewables. Such progressive disinvestment in the non-renewable resources that may be substituted with renewable resources is referred to as “Renewable Substitutability” and if implemented, this process will lead to a paradigm shift in the way building materials are manufactured. This paper discusses the development of a Renewable Substitutability Index (RSI that is designed to maximize the use of renewable resources in a building and quantifies the substitution process using solar emergy (i.e., the solar equivalent joules required for any item. The RSI of a building or a building component, i.e., floor or wall systems, etc., is the ratio of the renewable resources used during construction, including replacement and maintenance, to the building’s maximum renewable emergy potential. RSI values range between 0 and 1.0. A higher RSI achieves a low-energy building strategy promoting a higher order of sustainability by optimizing the use of renewables over a building’s lifetime from formation-extraction-manufacturing to maintenance, operation, demolition, and recycle.

  11. Managing the innovation supply chain to maximize personalized medicine.

    Science.gov (United States)

    Waldman, S A; Terzic, A

    2014-02-01

    Personalized medicine epitomizes an evolving model of care tailored to the individual patient. This emerging paradigm harnesses radical technological advances to define each patient's molecular characteristics and decipher his or her unique pathophysiological processes. Translated into individualized algorithms, personalized medicine aims to predict, prevent, and cure disease without producing therapeutic adverse events. Although the transformative power of personalized medicine is generally recognized by physicians, patients, and payers, the complexity of translating discoveries into new modalities that transform health care is less appreciated. We often consider the flow of innovation and technology along a continuum of discovery, development, regulation, and application bridging the bench with the bedside. However, this process also can be viewed through a complementary prism, as a necessary supply chain of services and providers, each making essential contributions to the development of the final product to maximize value to consumers. Considering personalized medicine in this context of supply chain management highlights essential points of vulnerability and/or scalability that can ultimately constrain translation of the biological revolution or potentiate it into individualized diagnostics and therapeutics for optimized value creation and delivery.

    Full Text Available Animals can maximize benefits but it is not known if they adjust their investment according to expected pay-offs. We investigated whether monkeys can use different investment strategies in an exchange task. We tested eight capuchin monkeys (Cebus apella and thirteen macaques (Macaca fascicularis, Macaca tonkeana in an experiment where they could adapt their investment to the food amounts proposed by two different experimenters. One, the doubling partner, returned a reward that was twice the amount given by the subject, whereas the other, the fixed partner, always returned a constant amount regardless of the amount given. To maximize pay-offs, subjects should invest a maximal amount with the first partner and a minimal amount with the second. When tested with the fixed partner only, one third of monkeys learned to remove a maximal amount of food for immediate consumption before investing a minimal one. With both partners, most subjects failed to maximize pay-offs by using different decision rules with each partner' quality. A single Tonkean macaque succeeded in investing a maximal amount to one experimenter and a minimal amount to the other. The fact that only one of over 21 subjects learned to maximize benefits in adapting investment according to experimenters' quality indicates that such a task is difficult for monkeys, albeit not impossible.

    2016-04-01

    Computer simulation tools for education and research are making increasingly effective use of the Internet and personal devices. To facilitate these activities in endocrinology and metabolism, a mechanistically based simulator of human thyroid hormone and thyrotropin (TSH) regulation dynamics was developed and further validated, and it was implemented as a facile and freely accessible web-based and personal device application: the THYROSIM app. This study elucidates and demonstrates its utility in a research context by exploring key physiological effects of over-the-counter thyroid supplements. THYROSIM has a simple and intuitive user interface for teaching and conducting simulated "what-if" experiments. User-selectable "experimental" test-input dosages (oral, intravenous pulses, intravenous infusions) are represented by animated graphical icons integrated with a cartoon of the hypothalamic-pituitary-thyroid axis. Simulations of familiar triiodothyronine (T3), thyroxine (T4), and TSH temporal dynamic responses to these exogenous stimuli are reported graphically, along with normal ranges on the same single interface page; and multiple sets of simulated experimental results are superimposable to facilitate comparative analyses. This study shows that THYROSIM accurately reproduces a wide range of published clinical study data reporting hormonal kinetic responses to large and small oral hormone challenges. Simulation examples of partial thyroidectomies and malabsorption illustrate typical usage by optionally changing thyroid gland secretion and/or gut absorption rates--expressed as percentages of normal--as well as additions of oral hormone dosing, all directly on the interface, and visualizing the kinetic responses to these challenges. Classroom and patient education usage--with public health implications--is illustrated by predictive simulated responses to nonprescription thyroid health supplements analyzed previously for T3 and T4 content. Notably, it was found that

  16. The role of the principle of double effect in ethics education at US medical schools and its potential impact on pain management at the end of life.

    Macauley, Robert

    2012-03-01

    Because opioids can suppress respiratory drive, the principle of double effect (PDE) has been used to justify their use for terminally ill patients. Recent studies, however, suggest that the risk of respiratory depression in typical end-of-life (EOL) situations may be overstated and that heightened concern for this rare occurrence can lead to inadequate treatment of pain. The purpose of this study is to examine the role of the PDE in medical school ethics education, with specific reference to its potential impact on pain management at EOL. After obtaining institutional review board approval, an electronic survey was sent to ethics educators at every allopathic medical school in the USA. One-third of ethics educators felt that opioids were 'likely' to cause significant respiratory depression that could hasten death. Educators' opinions of opioid effects did not influence their view of the relevance of the PDE, with approximately 70% deeming it relevant to EOL care. Only 15% of ethics educators believed that associating the PDE with opioid use might discourage clinicians from optimally treating pain, out of concern for respiratory depression. This study demonstrates that a significant minority of ethics educators believe, contrary to current evidence, that opioids are 'likely' to cause significant respiratory depression that could hasten death in terminally ill patients. Yet, many of those who do not feel this is likely still rely on the PDE to justify this possibility, potentially (and unknowingly) contributing to clinical misperceptions and underutilisation of opioids at EOL.

    The maximal slicing condition is a good time coordinate condition qualitatively when pursuing the gravitational collapse by the numerical calculation. The analytic solution of the gravitational collapse under the maximal slicing condition is given in the case of a spherical charged dust shell and the behavior of time slices with this coordinate condition is investigated. It is concluded that under the maximal slicing condition we can pursue the gravitational collapse until the radius of the shell decreases to about 0.7 x (the radius of the event horizon). (author)

    Absolutely maximally entangled (AME) states are pure multi-partite generalizations of the bipartite maximally entangled states with the property that all reduced states of at most half the system size are in the maximally mixed state. AME states are of interest for multipartite teleportation and quantum secret sharing and have recently found new applications in the context of high-energy physics in toy models realizing the AdS/CFT-correspondence. We work out in detail the connection between AME states of minimal support and classical maximum distance separable (MDS) error correcting codes and, in particular, provide explicit closed form expressions for AME states of n parties with local dimension \

    A Landau-Ginzburg-Wilson model associated with a single irreducible representation which exhibits an ordered phase whose symmetry group is not a maximal isotropy subgroup of the symmetry group of the disordered phase is constructed. This example disproves the maximality conjecture suggested in numerous previous studies. Below the (continuous) transition, the order parameter points along a direction which varies with the temperature and with the other parameters which define the model. An extension of the maximality conjecture to reducible representations was postulated in the context of Higgs symmetry breaking mechanism. Our model can also be extended to provide a counter example in these cases. (author)

    2011-12-01

    Full Text Available Abstract Background The use of gene signatures can potentially be of considerable value in the field of clinical diagnosis. However, gene signatures defined with different methods can be quite various even when applied the same disease and the same endpoint. Previous studies have shown that the correct selection of subsets of genes from microarray data is key for the accurate classification of disease phenotypes, and a number of methods have been proposed for the purpose. However, these methods refine the subsets by only considering each single feature, and they do not confirm the association between the genes identified in each gene signature and the phenotype of the disease. We proposed an innovative new method termed Minimize Feature's Size (MFS based on multiple level similarity analyses and association between the genes and disease for breast cancer endpoints by comparing classifier models generated from the second phase of MicroArray Quality Control (MAQC-II, trying to develop effective meta-analysis strategies to transform the MAQC-II signatures into a robust and reliable set of biomarker for clinical applications. Results We analyzed the similarity of the multiple gene signatures in an endpoint and between the two endpoints of breast cancer at probe and gene levels, the results indicate that disease-related genes can be preferably selected as the components of gene signature, and that the gene signatures for the two endpoints could be interchangeable. The minimized signatures were built at probe level by using MFS for each endpoint. By applying the approach, we generated a much smaller set of gene signature with the similar predictive power compared with those gene signatures from MAQC-II. Conclusions Our results indicate that gene signatures of both large and small sizes could perform equally well in clinical applications. Besides, consistency and biological significances can be detected among different gene signatures, reflecting the

  9. Maximal slicing of D-dimensional spherically symmetric vacuum spacetime

    International Nuclear Information System (INIS)

    Nakao, Ken-ichi; Abe, Hiroyuki; Yoshino, Hirotaka; Shibata, Masaru

    2009-01-01

    We study the foliation of a D-dimensional spherically symmetric black-hole spacetime with D≥5 by two kinds of one-parameter families of maximal hypersurfaces: a reflection-symmetric foliation with respect to the wormhole slot and a stationary foliation that has an infinitely long trumpetlike shape. As in the four-dimensional case, the foliations by the maximal hypersurfaces avoid the singularity irrespective of the dimensionality. This indicates that the maximal slicing condition will be useful for simulating higher-dimensional black-hole spacetimes in numerical relativity. For the case of D=5, we present analytic solutions of the intrinsic metric, the extrinsic curvature, the lapse function, and the shift vector for the foliation by the stationary maximal hypersurfaces. These data will be useful for checking five-dimensional numerical-relativity codes based on the moving puncture approach.

    Chen, Wei; Lin, Tian; Yang, Cheng

    2016-01-01

    Influence maximization is the task of finding a set of seed nodes in a social network such that the influence spread of these seed nodes based on certain influence diffusion model is maximized. Topic-aware influence diffusion models have been recently proposed to address the issue that influence between a pair of users are often topic-dependent and information, ideas, innovations etc. being propagated in networks are typically mixtures of topics. In this paper, we focus on the topic-aware influence maximization task. In particular, we study preprocessing methods to avoid redoing influence maximization for each mixture from scratch. We explore two preprocessing algorithms with theoretical justifications. Our empirical results on data obtained in a couple of existing studies demonstrate that one of our algorithms stands out as a strong candidate providing microsecond online response time and competitive influence spread, with reasonable preprocessing effort.

    Science.gov (United States)

    Pressé, Steve

    2014-11-01

    The maximum entropy method—used to infer probabilistic models from data—is a special case of Bayes's model inference prescription which, in turn, is grounded in basic propositional logic. By contrast to the maximum entropy method, the compatibility of nonadditive entropy maximization with Bayes's model inference prescription has never been established. Here we demonstrate that nonadditive entropy maximization is incompatible with Bayesian updating and discuss the immediate implications of this finding. We focus our attention on special cases as illustrations.

    Heart rate variability (HRV), blood pressure variability, (BPV) and heart rate recovery (HRR) are measures that provide insight regarding autonomic function. Maximal exercise can affect autonomic function, and it is unknown if there are sex differences in autonomic recovery following exercise. Therefore, the purpose of this study was to determine sex differences in several measures of autonomic function and the response following maximal exercise. Seventy-one (31 males and 40 females) healthy, nonsmoking, sedentary normotensive subjects between the ages of 18 and 35 underwent measurements of HRV and BPV at rest and following a maximal exercise bout. HRR was measured at minute one and two following maximal exercise. Males have significantly greater HRR following maximal exercise at both minute one and two; however, the significance between sexes was eliminated when controlling for VO2 peak. Males had significantly higher resting BPV-low-frequency (LF) values compared to females and did not significantly change following exercise, whereas females had significantly increased BPV-LF values following acute maximal exercise. Although males and females exhibited a significant decrease in both HRV-LF and HRV-high frequency (HF) with exercise, females had significantly higher HRV-HF values following exercise. Males had a significantly higher HRV-LF/HF ratio at rest; however, both males and females significantly increased their HRV-LF/HF ratio following exercise. Pre-menopausal females exhibit a cardioprotective autonomic profile compared to age-matched males due to lower resting sympathetic activity and faster vagal reactivation following maximal exercise. Acute maximal exercise is a sufficient autonomic stressor to demonstrate sex differences in the critical post-exercise recovery period.

    Microprocessor-controlled dc-to-dc power converters devised to maximize power transferred from solar photovoltaic strings to storage batteries and other electrical loads. Converters help in utilizing large solar photovoltaic arrays most effectively with respect to cost, size, and weight. Main points of invention are: single controller used to control and optimize any number of "dumb" tracker units and strings independently; power maximized out of converters; and controller in system is microprocessor.

    The paper presents an explicit solution to the problems of maximizing the area utilization coefficient and of obtaining the best approximation (on the average) of a sectorial Pi-shaped radiation pattern of an antenna with a circular aperture when Butterworth conditions are imposed on the approximating pattern with the aim of flattening it. Constraints on the choice of admissible minimum and maximum antenna dimensions are determined which make possible the synthesis of maximally flat patterns with small sidelobes.

    The paper presents an explicit solution to the problem of maximizing the aperture area utilization coefficient and obtaining the best approximation in the mean of the sectorial U-shaped radiation pattern of a linear antenna, when Butterworth flattening constraints are imposed on the approximating pattern. Constraints are established on the choice of the smallest and large antenna dimensions that make it possible to obtain maximally flat patterns, having a low sidelobe level and free from pulsations within the main lobe.

  17. No Mikheyev-Smirnov-Wolfenstein Effect in Maximal Mixing

    We investigate the possible influence of the MSW effect on the expectations for the solar neutrino experiments in the maximal mixing scenario suggested by the atmospheric neutrino data. A direct numerical calculation of matter induced effects in the Sun shows that the naive vacuum predictions are left completely undisturbed in the particular case of maximal mixing, so that the MSW effect turns out to be unobservable. We give a qualitative explanation of this result.

    We propose an optimal control problem to model the dynamics of the communication activity of a firm with the aim of maximizing its efficiency. We assume that the advertising effort undertaken by the firm contributes to increase the firm's goodwill and that the goodwill affects the firm's sales. The aim is to find the advertising policies in order to maximize the firm's efficiency index which is computed as the ratio between "outputs" and "inputs" properly weighted; the outputs are represented...

    A graph is chordal if every cycle of length greater than three contains an edge between non-adjacent vertices. Chordal graphs are of interest both theoretically, since they admit polynomial time solutions to a range of NP-hard graph problems, and practically, since they arise in many applications including sparse linear algebra, computer vision, and computational biology. A maximal chordal subgraph is a chordal subgraph that is not a proper subgraph of any other chordal subgraph. Existing algorithms for computing maximal chordal subgraphs depend on dynamically ordering the vertices, which is an inherently sequential process and therefore limits the algorithms' parallelizability. In this paper we explore techniques to develop a scalable parallel algorithm for extracting a maximal chordal subgraph. We demonstrate that an earlier attempt at developing a parallel algorithm may induce a non-optimal vertex ordering and is therefore not guaranteed to terminate with a maximal chordal subgraph. We then give a new algorithm that first computes and then repeatedly augments a spanning chordal subgraph. After proving that the algorithm terminates with a maximal chordal subgraph, we then demonstrate that this algorithm is more amenable to parallelization and that the parallel version also terminates with a maximal chordal subgraph. That said, the complexity of the new algorithm is higher than that of the previous parallel algorithm, although the earlier algorithm computes a chordal subgraph which is not guaranteed to be maximal. We experimented with our augmentation-based algorithm on both synthetic and real-world graphs. We provide scalability results and also explore the effect of different choices for the initial spanning chordal subgraph on both the running time and on the number of edges in the maximal chordal subgraph.

  20. On Maximally Dissipative Shock Waves in Nonlinear Elasticity

    Shock waves in nonlinearly elastic solids are, in general, dissipative. We study the following question: among all plane shock waves that can propagate with a given speed in a given one-dimensional nonlinearly elastic bar, which one—if any—maximizes the rate of dissipation? We find that the answer to this question depends strongly on the qualitative nature of the stress-strain relation characteristic of the given material. When maximally dissipative shocks do occur, they propagate according t...
