    Fraser, Doug

    In the face of escalating youth unemployment, some new approaches are needed for training out-of-school youth in Australia. The current system of apprenticeship has become outmoded because many of the skilled trades that the system prepares young people for will soon be non-existent. One approach to this problem has been implementation of…

    Full Text Available In this article, we try to analyze two things: (1 the characteristics of the neoliberal attack on school in general, in the age of “human capital”, and (2 what form this attack has acquired in our society. Today, one can see the subjugation of the school to economy in all developed capitalist countries, but if this subjugation is going on in some of the most developed countries, with unabated investment in education, then this attack is much more direct and raw in our society where government expects the subjugation of the school to the market while minimizing input into it. In both cases, it is a fact that this attack, which subordinates school to capital, could not have happened, or at least would have been less likely to occur, if it had not been accompanied by a new school discourse, to which teachers themselves contribute, either by remaining passive or by misunderstanding the contemporary school reality. The article mainly relies on the work of Christian Laval – L'École n'est pas une entreprise: Le néo-libéralisme à l'assaut de l'enseignement public.

    Fournier's gangrene is a rare but highly mortal infectious disease characterised by fulminant necrotising fasciitis involving the genital and perineal regions. The objective of this study is to analyse the demographics, clinical feature and treatment approaches as well as outcomes of Fournier's gangrene. Data were collected retrospectively from medical records and operative notes. Patient data were analysed by demographics, aetiological factors, clinical features, treatment approaches and outcomes. Twelve patients (five female and seven male) were enrolled in this study. The most common aetiology was perianal abscess (41·6%). Wound cultures showed a mixture of microorganisms in six (50%) patients. For faecal diversion, while colostomy was performed in six cases (50%), Flexi-Seal was used in two cases (16·6%). In four patients (33·4%), no faecal diversion was performed. Negative pressure wound therapy (NPWT) system was effective in the last four patients (33·4%). The mean hospitalisation period in patients who used NPWT was 18 days, while it was 20 days in the others. NPWT in Fournier's gangrene is a safe dressing method. It promotes granulation formation. Flexi-Seal faecal management is an alternative method to colostomy and provides protection from its associated complications. The combination of two devices (Flexi-Seal and NPWT) is an effective and comfortable method in the management of Fournier's gangrene in appropriate patients. © 2014 The Authors.

    Crawford, W H

    1986-05-01

    Total expenditures and revenues of 58 US dental school were derived from reports of the ADA Division of Educational Measurements. These financial data were studied by type of dental school (public, state-related private, and private) and by expenditure/revenue categories. Dental schools showed little diversity in expenditures: most were directed toward instruction; few were directed toward research or continuing education. Several distinctive patterns among the three types of dental schools in revenues were observed. Two configurations emerged: public and state-related private dental schools receive more than 75% of their revenues from government and tuition, and private dental schools, more than 50%.

  9. Low current approach to ignition

    Cenacchi, G.; Sugiyama, L.; Airoldi, A.; Coppi, B.

    1996-01-01

    The open-quotes standardclose quotes path to achieve ignition conditions so far has been that of producing plasmas with the maximum current and poloidal field that axe compatible with the applied toroidal field and the geometry of the adopted configuration (the low q a approach.) The other approach is that motivated by recent experiments with reversed shear configurations, with relatively low currents and high fields corresponding to high values of q a (e-g., q a ≅ 6). While the first approach can be pursued with ohmic heating alone, the second one necessarily involves an auxiliary heating system. One of the advantages of this approach is that the onset of large scale internal modes can be avoided as q(ψ) is kept above 1 over the entire plasma column. Since quite peaked density profiles are produced in the regimes where enhanced confinement is observed, the α-particle power levels for which ignition can be reached and therefore the thermal wall loading on the first wall, can be reduced relatively to the standard, low q a , approach. The possibility is considered that ignition is reached in the reversed shear, high q a , regime and that this is followed by a transition to non-reversed profiles, or even the low q a regime, assuming that the excitation of modes involving magnetic reconnection will not undermine the needed degree of confinement. These results have been demonstrated by numerical transport simulation for the Ignitor-Ult machine, but are applicable to all high field ignition experiments

    2017-03-01

    Liver injuries remain major obstacle for successful treatment, due to size and location of the liver. Requirement for surgery should be determined by clinical factors, most notably hemodynamical state. In this present study we tried to declare our approach to liver traumas. We also tried to emphasize the importance of conservative treatment, since surgeries for liver traumas carry high mortality rates. Patients admitted to the Department of Emergency Surgery at Kartal Research and Education Hospital, due to liver trauma were retrospectively analyzed between 2003 and 2013. Patient demographics, hepatic panel, APTT (activated partial thromboplastin time), PT (prothrombin time), INR (international normalized ratio), fibrinogen, biochemistry panel were recorded. Hemodynamic instability was the most prominent factor for surgery decision, in the lead of current Advanced Trauma Life Support (ATLS) protocols. Operation records and imaging modalities revealed liver injuries according to the Organ Injury Scale of the American Association for the Surgery of Trauma. 300 patients admitted to emergency department were included in our study (187 males and 113 females). Mean age was 47 years (range, 12-87). The overall mortality rate was 13% (40 out of 300). Major factor responsible for mortality rates and outcome was stability of cases on admission. 188 (% 63) patients were counted as stable, whereas 112 (% 37) cases were found unstable (blood pressure ≤ 90, after massive resuscitation). 192 patients were observed conservatively, whereas 108 cases received abdominal surgery. High levels of AST, ALT, LDH, INR, creatinine and low levels of fibrinogen and low platelet counts on admission were found to be associated with mortality and these cases also had Grade 4 and 5 injuries. Hemodynamic instability on admission and the type and grade of injury played major role in mortality rates). Packing was performed in 35 patients, with Grade 4 and 5 injuries. Mortality rate was %13 (40

    2015-06-01

    Full Text Available School refusal behavior refers to the avoidance of a child attending school and/or persistent difficulty staying in the classroom throughout the school day. Based on a review of the scientific literature, the aim of this study is to describe the current state of research on school refusal, differentiating between the findings and progress made in Spain from those achieved in the international field. For this purpose, the significance of this phenomenon, in addition to associated risk factors and variables, will be reviewed in the child and youth population. In turn, the commonly used assessment methods and most recommended treatment proposals, mainly based on cognitive behavioral therapy, are discussed. The results reveal several gaps and subjects for debate in some areas of knowledge about school refusal behavior, with differences being found between Spanish and international studies. In conclusion, future studies and challenges in this field are required.

    2015-01-01

    After decades of research, blindsight is still a mysterious and controversial topic in consciousness research. Currently, many researchers tend to think of it as an ideal phenomenon to investigate neural correlates of consciousness, whereas others believe that blindsight is in fact a kind...... of degraded vision rather than "truly blind". This article considers both perspectives and finds that both have difficulties understanding all existing evidence about blindsight. In order to reconcile the perspectives, we suggest two specific criteria for a good model of blindsight, able to encompass all...

Today, the international document related to childrens rights is the United Nations Convention on the Rights of the Child adoptedand approved by 193 countries. Child policy in Turkey where 25 million children live is an issue that should be seriously considered. Thus, childrens rights, children working in coordination with the contract on the basis of a policy should be implemented fully. [Cukurova Med J 2015; 40(1.000: 1-5

  19. [School shootings in Germany: current trends in the prevention of severe, targeted violence in German schools].

    Science.gov (United States)

    Bondü, Rebecca; Scheithauer, Herbert

    2009-01-01

    In March and September 2009 the school shootings in Winnenden and Ansbach once again demonstrated the need for preventive approaches in order to prevent further offences in Germany. Due to the low frequency of such offences and the low specificity of relevant risk factors known so far, prediction and prevention seems difficult though. None the less, several preventive approaches are currently discussed. The present article highlights these approaches and their specific advantages and disadvantages. As school shootings are multicausally determined, approaches focussing only on single aspects (i.e. prohibiting violent computer games or further strengthening gun laws) do not meet requirements. Other measures such as installing technical safety devices or optimizing actions of police and school attendants are supposed to reduce harm in case of emergency. Instead, scientifically founded and promising preventive approaches focus on secondary prevention and for this purpose employ the threat assessment approach, which is widespread within the USA. In this framework, responsible occupational groups such as teachers, school psychologists and police officers are to be trained in identifying students' warning signs, judging danger of these students for self and others in a systematic process and initiating suitable interventions.

  1. Childhood obesity: Current and novel approaches.

    Science.gov (United States)

    Sabin, Matthew A; Kiess, Wieland

    2015-06-01

    The prevalence of childhood obesity has increased over the last fifty years by approximately 5% per decade, and approximately a quarter of all children are now either overweight or obese. These children have a significantly increased risk of many future health problems including adult obesity, type 2 diabetes and heart disease. Despite this relentless increase, common-sense approaches aimed at prevention and treatment have failed to solve the problem. Current approaches at prevention have faced major challenges with some progress in implementing smaller scale programs and social marketing, but little action on broad public policy approaches which often appears unpalatable to society or individual governments. Meanwhile, treatment approaches have mainly focused on lifestyle change, and novel approaches are urgently needed. Prevention needs to shift to improving maternal health prior to conception, with more research focussed on the impact of early years in programming offspring to future overweight/obesity. Likewise, treatment paradigms need to move from simply thinking that obesity can be solved by readdressing diet and activity levels. Novel approaches are needed which take into consideration the complex physiology which regulates early childhood growth and the development of obesity in susceptible individuals.

    Karam, Ricardo; Coimbra, Debora; Pietrocola, Maurício

    2014-08-01

    Due to its fundamental role for the consolidation of Maxwell's equations, the displacement current is one of the most important topics of any introductory course on electromagnetism. Moreover, this episode is widely used by historians and philosophers of science as a case study to investigate several issues (e.g. the theory-experiment relationship). Despite the consensus among physics educators concerning the relevance of the topic, there are many possible ways to interpret and justify the need for the displacement current term. With the goal of understanding the didactical transposition of this topic more deeply, we investigate three of its domains: (1) The historical development of Maxwell's reasoning; (2) Different approaches to justify the term insertion in physics textbooks; and (3) Four lectures devoted to introduce the topic in undergraduate level given by four different professors. By reflecting on the differences between these three domains, significant evidence for the knowledge transformation caused by the didactization of this episode is provided. The main purpose of this comparative analysis is to assist physics educators in developing an epistemological surveillance regarding the teaching and learning of the displacement current.

  6. A multilayer approach for turbidity currents

    Science.gov (United States)

    Fernandez-Nieto, Enrique; Castro Díaz, Manuel J.; Morales de Luna, Tomás

    2017-04-01

    When a river that carries sediment in suspension enters into a lake or the ocean it can form a plume that can be classified as hyperpycnal or hypopycnal. Hypopycnal plumes occurs if the combined density of the sediment and interstitial fluid is lower than that of the ambient. Hyperpycnal plumes are a class of sediment-laden gravity current commonly referred to as turbidity currents [7,9]. Some layer-averaged models have been previously developed (see [3, 4, 8] among others). Although this layer-averaged approach gives a fast and valuable information, it has the disadvantage that the vertical distribution of the sediment in suspension is lost. A recent technique based on a multilayer approach [1, 2, 6] has shown to be specially useful to generalize shallow water type models in order to keep track of the vertical components of the averaged variables in the classical shallow water equations. In [5] multilayer model is obtained using a vertical discontinuous Galerkin approach for which the vertical velocity is supposed to be piecewise linear and the horizontal velocity is supposed to be piecewise constant. In this work the technique introduced in [5] is generalized to derive a model for turbidity currents. This model allows to simulate hyperpycnal as well as hypopycnal plumes. Several numerical tests will be presented. References [1] E. Audusse, M. Bristeau, B. Perthame, and J. Sainte-Marie.

  8. Computational approaches to analogical reasoning current trends

    CERN Document Server

    Richard, Gilles

    2014-01-01

    Analogical reasoning is known as a powerful mode for drawing plausible conclusions and solving problems. It has been the topic of a huge number of works by philosophers, anthropologists, linguists, psychologists, and computer scientists. As such, it has been early studied in artificial intelligence, with a particular renewal of interest in the last decade. The present volume provides a structured view of current research trends on computational approaches to analogical reasoning. It starts with an overview of the field, with an extensive bibliography. The 14 collected contributions cover a large scope of issues. First, the use of analogical proportions and analogies is explained and discussed in various natural language processing problems, as well as in automated deduction. Then, different formal frameworks for handling analogies are presented, dealing with case-based reasoning, heuristic-driven theory projection, commonsense reasoning about incomplete rule bases, logical proportions induced by similarity an...

    Over the past decade, significant advances have been made in the field of subarachnoid haemorrhage (SAH). Prompt diagnosis with high-resolution CT and intensive critical care support remain key aspects of good patient management. Early identification and definitive treatment of underlying ruptured aneurysms is generally advocated to reduce the risk of re-bleeding, a complication with high mortality and morbidity. Although intra-arterial digital subtraction angiography (DSA) is still considered the gold standard for sourcing aneurysms, CT angiography, especially with the evolution of multi-slice technology, is slowly gaining acceptance as a rapid, accessible and minimally invasive method which appears likely to replace DSA as first-line modality in the future. Furthermore, the advent of Guglielmi detachable coils and the ISAT trial have revolutionised the treatment of ruptured aneurysms, with a significant trend towards endovascular coiling away from operative clipping. Improvements in clinical experience, coiling technology and assistive devices now allow interventionalists to potentially treat the majority of aneurysms, including wide-necked or complex lesions. The uncertain long-term results of coiling, however, still fuel strong debate and controversy. This review summarises current diagnostic approaches to SAH from a radiological perspective, with an emphasis on aneurysmal SAH and an evidence-based approach to the role of imaging and interventional radiology in diagnosis, treatment and follow-up.

    Billiard, Michel

    2008-01-01

    The management of narcolepsy is presently at a turning point. Three main avenues are considered in this review: 1) Two tendencies characterize the conventional treatment of narcolepsy. Modafinil has replaced methylphenidate and amphetamine as the first-line treatment of excessive daytime sleepiness (EDS) and sleep attacks, based on randomized, double blind, placebo-controlled clinical trials of modafinil, but on no direct comparison of modafinil versus traditional stimulants. For cataplexy, sleep paralysis, and hypnagogic hallucinations, new antidepressants tend to replace tricyclic antidepressants and selective serotonin reuptake inhibitors (SSRIs) in spite of a lack of randomized, double blind, placebo-controlled clinical trials of these compounds; 2) The conventional treatment of narcolepsy is now challenged by sodium oxybate, the sodium salt of gammahydroxybutyrate, based on a series of randomized, double-blind, placebo-controlled clinical trials and a long-term open label study. This treatment has a fairly good efficacy and is active on all symptoms of narcolepsy. Careful titration up to an adequate level is essential both to obtain positive results and avoid adverse effects; 3) A series of new treatments are currently being tested, either in animal models or in humans, They include novel stimulant and anticataplectic drugs, endocrine therapy, and, more attractively, totally new approaches based on the present state of knowledge of the pathophysiology of narcolepsy with cataplexy, hypocretine-based therapies, and immunotherapy.

For cataplexy, sleep paralysis, and hypnagogic hallucinations, new antidepressants tend to replace tricyclic antidepressants and selective serotonin reuptake inhibitors (SSRIs in spite of a lack of randomized, double blind, placebo-controlled clinical trials of these compounds; 2 The conventional treatment of narcolepsy is now challenged by sodium oxybate, the sodium salt of gammahydroxybutyrate, based on a series of randomized, double-blind, placebo-controlled clinical trials and a long-term open label study. This treatment has a fairly good efficacy and is active on all symptoms of narcolepsy. Careful titration up to an adequate level is essential both to obtain positive results and avoid adverse effects; 3 A series of new treatments are currently being tested, either in animal models or in humans, They include novel stimulant and anticataplectic drugs, endocrine therapy, and, more attractively, totally new approaches based on the present state of knowledge of the pathophysiology of narcolepsy with cataplexy, hypocretine-based therapies, and immunotherapy.Keywords: narcolepsy, treatment, conventional drugs, modafinil, sodium oxybate, future treatments

    2014-06-01

    Full Text Available Cyberbullying is a common phenomenon amongst young people. It exhibits many similarities to traditional school bullying, with a potentially serious impact on the mental health and school functioning of victims. For this reason, action by schools is often recommended. The aim of this article is to provide a better picture of what schools are currently doing to address cyberbullying and of what schools will need to continue doing so in the future. An online survey was conducted among staff members of 309 primary and secondary schools in Flanders, which is the Dutch speaking part of Belgium. The questionnaire measured the schools’ experiences with cyberbullying and their perceived responsibility and efficacy in dealing with this issue as well as their concrete preventive, detective, and reactive actions. The results indicate that, although most schools are aware of relatively few cases of cyberbullying, they do consider cyberbullying to be a problem. Many schools consider it their duty to inform students about cyberbullying and to help find solutions to cyberbullying incidents involving students, even if they take place away from the school grounds or outside school hours. Although most schools organize concrete actions with regard to cyberbullying, they often seem uncertain about the appropriateness and effectiveness of their actions. They would welcome evidence-based intervention programmes that would appeal to their students.

    Full Text Available Abstract Many different approaches have been developed to model and simulate gene regulatory networks. We proposed the following categories for gene regulatory network models: network parts lists, network topology models, network control logic models, and dynamic models. Here we will describe some examples for each of these categories. We will study the topology of gene regulatory networks in yeast in more detail, comparing a direct network derived from transcription factor binding data and an indirect network derived from genome-wide expression data in mutants. Regarding the network dynamics we briefly describe discrete and continuous approaches to network modelling, then describe a hybrid model called Finite State Linear Model and demonstrate that some simple network dynamics can be simulated in this model.

    Guro, Hanisah; Kim, Jin Won; Choi, YoungRok; Cho, Jai Young; Yoon, Yoo-Seok; Han, Ho-Seong

    2017-06-01

    Intrahepatic cholangiocarcinoma (ICC) is a common primary hepatic tumor. However, its outcomes are usually worse than those of hepatocellular carcinoma owing to its non-specific presentation and detection at an advanced stage. The most widely used serum marker, carbohydrate antigen 19-9, is non-specific. Furthermore, imaging studies rarely identify any pathognomonic features. Surgery is the only treatment option that offers a chance of long-term survival. However, the resectability rate is low owing to the high frequencies of intrahepatic metastases, peritoneal carcinomatosis, or extrahepatic metastases. Surgical treatment should be tailored according to the macroscopic classification of ICC (e.g. mass-forming, periductal infiltrating, and intraductal growth types) because it reflects the tumor's dissemination pattern. Although lymph node metastasis is a negative prognostic factor, the importance and extent of lymph node dissection is still controversial. To improve patient survival, liver transplantation is considered in some patients with unresectable ICC, especially in those with an insufficient remnant liver volume. Minimally invasive procedures, including laparoscopic and robotic liver resection, have been tested and achieved comparable outcomes to conventional surgery in preliminary studies. No randomized trials have confirmed the efficacy of adjuvant chemotherapy in ICC, and several trials have evaluated molecular-targeted agents as monotherapy or in combination with cytotoxic chemotherapy. Multidisciplinary approaches are necessary to improve the outcomes of ICC. Copyright © 2017 Elsevier Ltd. All rights reserved.

  8. CURRENT APPROACHES TO CHEMORADIOTHERAPY FOR MALIGNANT GLIOMAS

    Directory of Open Access Journals (Sweden)

    Ye. L. Choinzonov

    2014-01-01

    Full Text Available High-grade malignant gliomas (WHO grade G III–IV account for more than 50% of all primary brain tumors. Despite aggressive treatment, survival rates are still very low with a median reported survival of no more than 1.5 years.Radiation therapy is an integral part of the combined treatment, but often does not influence lethally on resistant tumor cells. Thereby, in recent decades there has been an active search for novel approaches to the treatment of malignant gliomas (chemotherapeutic drugs, biological modifiers, local hyperthermia. Experimental data showed that the effect of high temperatures has both a direct damaging effect on tumor cells and a sensitizing effect. Significant advantages are achieved when the complex treatment of different malignant tumorsincludes local hyperthermia. However data on the treatment of patients with primary and recurrent gliomas G III–IV using local hyperthermia are scarce.The literature review is given in the article provides an overview of the existing treatment methods for brain tumors.

  9. Pulp regeneration: Current approaches and future challenges

    Directory of Open Access Journals (Sweden)

    Jingwen eYANG

    2016-03-01

    Full Text Available Regenerative endodontics aims to replace inflamed/necrotic pulp tissues with regenerated pulp-like tissues to revitalize teeth and improve life quality. Pulp revascularization case reports, which showed successful clinical and radiographic outcomes, indicated the possible clinical application of pulp regeneration via cell homing strategy. From a clinical point of view, functional pulp-like tissues should be regenerated with the characterization of vascularization, re-innervation, and dentin deposition with a regulated rate similar to that of normal pulp. Efficient root canal disinfection and proper size of the apical foramen are the two requisite preconditions for pulp regeneration. Progress has been made on pulp regeneration via cell homing strategies. This review focused on the requisite preconditions and cell homing strategies for pulp regeneration. In addition to the traditionally used mechanical preparation and irrigation, antibiotics, irrigation assisted with EndoVac apical negative-pressure system, and ultrasonic and laser irradiation are now being used in root canal disinfection. In addition, pulp-like tissues could be formed with the apical foramen less than 1 mm, although more studies are needed to determine the appropriate size. Moreover, signaling molecules including stromal cell derived factor (SDF-1α, basic Fibroblast Growth Factor (bFGF, Platelet Derived Growth Factor (PDGF, stem cell factor (SCF, and Granulocyte Colony-Stimulating Factor (G-CSF were used to achieve pulp-like tissue formation via a cell homing strategy. Studies on the cell sources of pulp regeneration might give some indications on the signaling molecular selection. The active recruitment of endogenous cells into root canals to regenerate pulp-like tissues is a novel concept that may offer an unprecedented opportunity for the near-term clinical translation of current biology-based therapies for dental pulp regeneration.

    The tradional "lectures delivering" approach to classroom teachers used by mental health practitioners is investigated in the present study. An attempt is made to demonstrate the validity of preventative work in helping elementary school teachers as important agents in the promotion of more positive mental hygiene in the classroom and by adding to the lectures the variable of group therapy--"ego-sparing" techniques type. The latter approach seems to promote a teacher's own sense of security in dealing the pupils, an easier acceptance of differences in others, and, finally, it tends to stimulate the development of a teacher's own ability to deal sensibly, more conscientiously, and more realistically with daily problems.

    Full Text Available Vocational Schools which have undertaken various missions throughout history were established in order to train intermediate staff s with suff icient knowledge and skills in their fields, in accordance with the requirements of trade, industry and services sectors and they are the most important components of ‘vocational and technical education system' today. Analyzing the education given in the vocational schools in accordance with the national and international requirements, developing technologies and the needs of business world and making the necessary arrangements in line with these will contribute to the employability and preferability of graduates of these schools in an eff icient way. Many industrialists/businessmen in our country stated that they experienced serious problems in the supply of qualified staff with suff icient knowledge and skills needed in sectors. Although much progress has been achieved in this subject, it is a fact that there are still a lot of work to be done. In this study, current situation and main troubles in vocational schools are discussed in the light of the experiences gained at Hitit University Vocational School which was established about 40 years ago in Çorum and which is one of the first high schools in Turkey and some solutions are suggested in accordance with the problems mentioned.

    Sport specialization is a strategy to acquire superior sport performance in 1 sport but is associated with increased injury risk. Currently, the degree of high school specialization among Division I athletes is unknown. College athletes will display increased rates of specialization as they progress through their high school careers. Descriptive epidemiological study. Level 4. Three hundred forty-three athletes (115 female) representing 9 sports from a Midwest Division I University completed a previously utilized sport specialization questionnaire regarding sport participation patterns for each grade of high school. McNemar and chi-square tests were used to investigate associations of grade, sport, and sex with prevalence of sport specialization category (low, moderate, high) (a priori P ≤ 0.05). Specialization increased throughout high school, with 16.9% (n = 58) and 41.1% (n = 141) of athletes highly specialized in 9th and 12th grades, respectively. Football athletes were less likely to be highly specialized than nonfootball athletes for each year of high school ( P 0.23). The majority of Division I athletes were not classified as highly specialized throughout high school, but the prevalence of high specialization increased as athletes progressed through high school. Nonfootball athletes were more likely to be highly specialized than football athletes at each grade level. Most athletes who are recruited to participate in collegiate athletics will eventually specialize in their sport, but it does not appear that early specialization is necessary to become a Division I athlete. Athletes should be counseled regarding safe participation in sport during high school to minimize injury and maximize performance.

    Cigarette smoking in adolescent is a significant public health problem, leading to the risk of addiction, morbidity, and mortality in the long term. This study determined the prevalence and correlates of current smoking among adolescent school children. A nationwide school-based survey among 25 507 students between Forms 1 to 5 (aged 12-17) was conducted using a 2-stage cluster sampling design. The prevalence of current smoking was 11.5%. Multivariable logistic regression analysis revealed that current smoking was significantly associated with males (adjusted odds ratio [aOR] = 3.25; 95% confidence interval [CI] = 1.87, 4.98), current drinking (aOR = 2.34; 95% CI = 1.46, 3.74), drug used (aOR = 2.97; 95% CI = 1.24, 7.11), and being bullied (aOR = 1.41; 95% CI = 1.00, 1.98) at least once in the past 12 months. Smoking is associated with several behaviors that pose risks to adolescents, such as social issues and smoking-related health problems. Thus, early and integrated prevention programs that address multiple risk behaviors simultaneously are required. © 2014 APJPH.

    Science.gov (United States)

    Naz, R.; Mahomed, F. M.; Chaudhry, Azam

    2014-10-01

    We develop a partial Hamiltonian framework to obtain reductions and closed-form solutions via first integrals of current value Hamiltonian systems of ordinary differential equations (ODEs). The approach is algorithmic and applies to many state and costate variables of the current value Hamiltonian. However, we apply the method to models with one control, one state and one costate variable to illustrate its effectiveness. The current value Hamiltonian systems arise in economic growth theory and other economic models. We explain our approach with the help of a simple illustrative example and then apply it to two widely used economic growth models: the Ramsey model with a constant relative risk aversion (CRRA) utility function and Cobb Douglas technology and a one-sector AK model of endogenous growth are considered. We show that our newly developed systematic approach can be used to deduce results given in the literature and also to find new solutions.

  3. Adjoint current-based approaches to prostate brachytherapy optimization

    International Nuclear Information System (INIS)

    Roberts, J. A.; Henderson, D. L.

    2009-01-01

    This paper builds on previous work done at the Univ. of Wisconsin - Madison to employ the adjoint concept of nuclear reactor physics in the so-called greedy heuristic of brachytherapy optimization. Whereas that previous work focused on the adjoint flux, i.e. the importance, this work has included use of the adjoint current to increase the amount of information available in optimizing. Two current-based approaches were developed for 2-D problems, and each was compared to the most recent form of the flux-based methodology. The first method aimed to take a treatment plan from the flux-based greedy heuristic and adjust via application of the current-displacement, or a vector displacement based on a combination of tissue (adjoint) and seed (forward) currents acting as forces on a seed. This method showed promise in improving key urethral and rectal dosimetric quantities. The second method uses the normed current-displacement as the greedy criterion such that seeds are placed in regions of least force. This method, coupled with the dose-update scheme, generated treatment plans with better target irradiation and sparing of the urethra and normal tissues than the flux-based approach. Tables of these parameters are given for both approaches. In summary, these preliminary results indicate adjoint current methods are useful in optimization and further work in 3-D should be performed. (authors)

    2013-01-01

    Osteosarcoma is the most frequent malignant primary bone tumor and a main cause of cancer-related death in children and adolescents. Although long-term survival in localized osteosarcoma has improved to about 60% during the 1960s and 1970s, long-term survival in both localized and metastatic osteosarcoma has stagnated in the past several decades. Thus, current conventional therapy consists of multi-agent chemotherapy, surgery and radiation, which is not fully adequate for osteosarcoma treatment. Innovative drugs and approaches are needed to further improve outcome in osteosarcoma patients. This review describes the current management of osteosarcoma as well as potential new therapies

    Ord, R A; Blanchaert, R H

    2001-11-01

    Recent basic science discoveries have contributed to our understanding of the etiology of oral cancer and allowed us to consider innovative approaches to therapy. The authors evaluated and summarized current approaches to the management of oral cancer, emphasizing the multidisciplinary team approach to coordinate surgery, radiation therapy and chemotherapy. Current concepts in management, including complications of therapy, are described. State-of-the-art surgical techniques can spare patients with oral cancer from much of the morbidity and complications common in the past. The refinement of treatment strategies reduces complications and improves efficacy. Many exciting new clinical trials in the areas of gene therapy and immunomodulation are showing promise. Management of oral cancer has undergone radical change in the past 10 years and continues to evolve rapidly. Discoveries in molecular biology, diagnosis, surgery, radiation therapy and medical oncology have altered many traditional concepts and practices. General dental practitioners need to understand current treatment modalities for oral and pharyngeal cancers to determine to whom they should refer patients for the most appropriate treatment, and to make recommendations regarding complications associated with these cancers.

    2017-01-01

    This study builds on a fieldwork in a Danish school class, where pupils were observed while preparing and eating school meals. It shows that the children encounter conflicting approaches to food education depending on the context. While eating, an authoritarian approach to food education dominates...... and food is ascribed instrumental value. While preparing the school meal, a democratic approach dominates and food is ascribed intrinsic value. The aim is to show how these conflicting approaches reflect not only different social and cultural expectations to eating and preparing meals, respectively......, but also a conflict between food educational ideals and actual school meal practices. To illustrate this an analytic model is introduced, the Integrated Food Pedagogy Model, and the ways in which this model could help promote better food education among schoolchildren are discussed....

  19. Optimizing nitrogen fertilizer use: Current approaches and simulation models

    International Nuclear Information System (INIS)

    Baethgen, W.E.

    2000-01-01

    Nitrogen (N) is the most common limiting nutrient in agricultural systems throughout the world. Crops need sufficient available N to achieve optimum yields and adequate grain-protein content. Consequently, sub-optimal rates of N fertilizers typically cause lower economical benefits for farmers. On the other hand, excessive N fertilizer use may result in environmental problems such as nitrate contamination of groundwater and emission of N 2 O and NO. In spite of the economical and environmental importance of good N fertilizer management, the development of optimum fertilizer recommendations is still a major challenge in most agricultural systems. This article reviews the approaches most commonly used for making N recommendations: expected yield level, soil testing and plant analysis (including quick tests). The paper introduces the application of simulation models that complement traditional approaches, and includes some examples of current applications in Africa and South America. (author)

    The evolution and development of opinions on the diagnosis and treatment of breast cancer since Galen to present time is presented. The concept of breast cancer as a local disease has been replaced by the understanding of its systemic character. On this background described are the methods of surgical treatment beginning from early - supraradical, to present -conservative approaches. The ''milestones'' in diagnosis and treatment of breast cancer of the last 40 years are presented. Current methods of breast cancer management include correct diagnosis (clinical examination, mammography, ultrasound, fine needle aspiration biopsy), TNM staging, adequate loco-regional therapy, systemic therapy, rehabilitation, reconstruction and careful follow-up.

    The new low-energy AP 3 -interaction, which is produced by convergent box-constituent-quark-loop diagrams, is obtained within chiral perturbation theory at the quark level (CHPT) q with linear realization of chiral U(3) x U(3) symmetry. Its contributions to processes of low-energy interactions of low-lying mesons are investigated. The new interaction goes beyond the framework of the low-energy current algebra approach and of the effective chiral Lagrangians with linear realization of chiral symmetry, constructed at the hadronic level.

    Full Text Available The Electrostatic Discharge phenomenon is a great threat to all electronic devices and ICs. An electric charge passing rapidly from a charged body to another can seriously harm the last one. However, there is a lack in a linear mathematical approach which will make it possible to design a circuit capable of producing such a sophisticated current waveform. The commonly accepted Electrostatic Discharge current waveform is the one set by the IEC 61000-4-2. However, the over-simplified circuit included in the same standard is incapable of producing such a waveform. Treating the Electrostatic Discharge current waveform of the IEC 61000-4-2 as reference, an approximation method, based on Prony’s method, is developed and applied in order to obtain a linear system’s response. Considering a known input, a method to design a circuit, able to generate this ESD current waveform in presented. The circuit synthesis assumes ideal active elements. A simulation is carried out using the PSpice software.

    The role of schools in providing community-based support for children's mental health and well-being is widely accepted and encouraged. Research has mainly focused on designing and evaluating specific interventions and there is little data available regarding what provision is available, the focus and priorities of schools and the professionals involved in providing this support. The current study presents these data from schools in 10 European countries. Online survey of 1466 schools in France, Germany, Ireland, Netherlands, Poland, Serbia, Spain, Sweden, UK and Ukraine. The participating countries were chosen based on their geographical spread, diversity of political and economic systems, and convenience in terms of access to the research group and presence of collaborators. Schools reported having more universal provision than targeted provision and there was greater reported focus on children who already have difficulties compared with prevention of problems and promotion of student well-being. The most common interventions implemented related to social and emotional skills development and anti-bullying programmes. Learning and educational support professionals were present in many schools with fewer schools reporting involvement of a clinical specialist. Responses varied by country with 7.4-33.5% between-country variation across study outcomes. Secondary schools reported less support for parents and more for staff compared with primary schools, with private schools also indicating more staff support. Schools in rural locations reported less student support and professionals involved than schools in urban locations. The current study provides up-to-date and cross-country insight into the approaches, priorities and provision available for mental health support in schools; highlighting what schools prioritise in providing mental health support and where coverage of provision is lacking.

    Both the general public and individual patients expect healthcare providers to be knowledgeable and approachable regarding sexual health. Despite this expectation there are no universal standards or expectations regarding the sexuality education of medical students. To review the current state of the art in sexuality education for North American medical students and to articulate future directions for improvement. Evaluation of: (i) peer-reviewed literature on sexuality education (focusing on undergraduate medical students); and (ii) recommendations for sexuality education from national and international public health organizations. Current status and future innovations for sexual health education in North American medical schools. Although the importance of sexuality to patients is recognized, there is wide variation in both the quantity and quality of education on this topic in North American medical schools. Many sexual health education programs in medical schools are focused on prevention of unwanted pregnancy and sexually transmitted infection. Educational material on sexual function and dysfunction, female sexuality, abortion, and sexual minority groups is generally scant or absent. A number of novel interventions, many student initiated, have been implemented at various medical schools to improve the student's training in sexual health matters. There is a tremendous opportunity to mold the next generation of healthcare providers to view healthy sexuality as a relevant patient concern. A comprehensive and uniform curriculum on human sexuality at the medical school level may substantially enhance the capacity of tomorrow's physicians to provide optimal care for their patients irrespective of gender, sexual orientation, and individual sexual mores/beliefs. © 2013 International Society for Sexual Medicine.

    There are currently no accepted regulatory models for assessing the potential of a substance to cause respiratory sensitization and allergy. In contrast, a number of models exist for the assessment of contact sensitization and allergic contact dermatitis (ACD). Research indicates that respiratory sensitizers may be identified through contact sensitization assays such as the local lymph node assay, although only a small subset of the compounds that yield positive results in these assays are actually respiratory sensitizers. Due to the increasing health concerns associated with occupational asthma and the impending directives on the regulation of respiratory sensitizers and allergens, an approach which can identify these compounds and distinguish them from contact sensitizers is required. This report discusses some of the important contrasts between respiratory allergy and ACD, and highlights several prominent in vivo, in vitro and in silico approaches that are being applied or could be further developed to identify compounds capable of causing respiratory allergy. Although a number of animal models have been used for researching respiratory sensitization and allergy, protocols and endpoints for these approaches are often inconsistent, costly and difficult to reproduce, thereby limiting meaningful comparisons of data between laboratories and development of a consensus approach. A number of emerging in vitro and in silico models show promise for use in the characterization of contact sensitization potential and should be further explored for their ability to identify and differentiate contact and respiratory sensitizers. Ultimately, the development of a consistent, accurate and cost-effective model will likely incorporate a number of these approaches and will require effective communication, collaboration and consensus among all stakeholders

  10. Current Approaches to the Establishment of Credit Risk Specific Provisions

    Full Text Available The aim of the new Basel II and IFRS approaches is to make the operations of financial institutions more transparent and thus to create a better basis for the market participants and supervisory authorities to acquire information and make decisions. In the banking sector, a continuous debate is being led, related to the similarities and differences between IFRS approach on loan loss provisions and Basel II approach on calculating the capital requirements, judging against the classical method regarding loan provisions, currently used by the Romanian banks following the Central Bank’s regulations.Banks must take into consideration that IFRS and Basel II objectives are fundamentally different. While IFRS aims to ensure that the financial papers reflect adequately the losses recorded at each balance sheet date, the Basel II objective is to ensure that the bank has enough provisions or capital in order to face expected losses in the next 12 months and eventual unexpected losses.Consequently, there are clear differences between the objectives of the two models. Basel II works on statistical modeling of expected losses while IFRS, although allowing statistical models, requires a trigger event to have occurred before they can be used. IAS 39 specifically states that losses that are expected as a result of future events, no matter how likely, are not recognized. This is a clear and fundamental area of difference between the two frameworks.

  11. Towards an Airframe Noise Prediction Methodology: Survey of Current Approaches

    Farassat, Fereidoun; Casper, Jay H.

    2006-01-01

    In this paper, we present a critical survey of the current airframe noise (AFN) prediction methodologies. Four methodologies are recognized. These are the fully analytic method, CFD combined with the acoustic analogy, the semi-empirical method and fully numerical method. It is argued that for the immediate need of the aircraft industry, the semi-empirical method based on recent high quality acoustic database is the best available method. The method based on CFD and the Ffowcs William- Hawkings (FW-H) equation with penetrable data surface (FW-Hpds ) has advanced considerably and much experience has been gained in its use. However, more research is needed in the near future particularly in the area of turbulence simulation. The fully numerical method will take longer to reach maturity. Based on the current trends, it is predicted that this method will eventually develop into the method of choice. Both the turbulence simulation and propagation methods need to develop more for this method to become useful. Nonetheless, the authors propose that the method based on a combination of numerical and analytical techniques, e.g., CFD combined with FW-H equation, should also be worked on. In this effort, the current symbolic algebra software will allow more analytical approaches to be incorporated into AFN prediction methods.

    Full Text Available In modern economies, current research generally acknowledges that the central issues in macroeconomics are essentially the same as those identified by Keynes in the General Theory of Employment, Interest and Money. One way or the other, economists are trying to address the same macroeconomic issues that they did seven decades ago: How can we account for the different growth rates and various fluctuations observed in national economies? Which are the economic policies most suitable to solve the issues of growth and cyclic behavior? Both the new classicals and the new Keynesians have made considerable progress within their research paradigms: to explain economic fluctuations, the new classicals focus on technological perturbations, the intertemporal substitution of leisure and real business cycles; on the other hand, the new Keynesians speak in terms of monopolistic competition, menu costs or efficiency wages. On the whole, the new classicals believe that the business cycle can best be understood within the market-clearing model, whereas the new keynesians believe that business fluctuations are due to certain market failures of various sorts.The present paper focuses on the main directions of research of the new classical school on the business cycle, given that the theoretical progress in this field has been significant and relevant for economic policy during the past four decades.

  14. Current Approaches for Control Room I and C Modernization

    International Nuclear Information System (INIS)

    Lopez, Alberto; Jimenez, Alfonso

    2002-01-01

    In general, instrumentation and control (I and C) systems for nuclear power plants were made using analogic systems and relays, since this was the only technology available by the time these systems were designed. This fact impacts on the operational and maintenance capabilities required to these systems. For this reason, nuclear power plants are facing nowadays two challenges: on one hand, the obsolescence of these systems contributes to the increase in the operation and maintenance costs - due to the difficulties for getting spare parts and support from the system vendors -. On the other hand, there has been an increase in the utilities competitiveness due to the electric power market liberalization. All this, of course, along with the commitment to maintain the current safety levels and meet the new requirements and standards that may arise in the near future. The application of current technologies, especially digital technology, solves the obsolescence problems and allows for a more functional and updated human-machine interface. Nevertheless, the cost associated to these modifications makes it necessary to develop strategies to determine which systems need to be modified and how to implement modifications effectively, so that these systems can work jointly with others using different technologies. Other issues inherent to digital technology must be considered, such as verification and validation of the software and of the human-machine interface, which are required for its licensing. This presentation describes the current approaches for I and C modernization, the main reasons, technologies and implementation plans, focusing on the control room and on the impact on operations. The main issues to be considered for developing a specific modernization plan are analysed. The goals and status of the 'Feasibility Study of the Control Room I and C Modernization' are described. This study is currently being developed by Endesa, Iberdrola and Tecnatom, and is included

    Flavour observables impose strong constraints on models of new physics. We study whether right-handed currents can provide a realistic extension to the Standard Model. We analyse two complementary models. These setups lead to new flavour violating interactions in the right-handed sector. We first consider a bottom-up approach assuming a left-right symmetric flavour group broken only by the Yukawa couplings. In this model the vertical stroke V ub vertical stroke problem can be solved. Secondly we study the Left-Right Model. We perform a comprehensive numerical analysis, including all known experimental constraints from ΔF=2 observables and the decay B →X s γ simultaneously. We observe that there exist regions in parameter space in accordance with the all data. In this model all flavour anomalies can be resolved except the vertical stroke V ub vertical stroke problem.

    Full Text Available In recent years, there has been a trend toward changing the clinical concept of osteoarthritis (OA. This disease has been considered as an age-related disease and the long-term result of a current pathological process for a very long time. However, many experts are now inclined to consider it necessary to identify the early, pre-X-ray stage of OA, when adequate treatment may not only halt the progression, but also achieve the regression of joint structural changes. This review deals with a number of pathogenetic and clinical aspects of the early stages of OA, which are important for timely diagnosis and pathogenetic therapy choice. It also considers some therapeutic approaches, both a "classic" and recently actively discussed methods for using platelet-rich plasma and autologous chondrocyte transplantation.

  1. Approaches to School Leadership in Inclusive STEM High Schools: A Cross-Case Analysis

    Science.gov (United States)

    Ford, Michael Robert

    Inclusive STEM-focused high schools (ISHSs) are a relatively new phenomenon in the landscape of public education. This study of four exemplar ISHSs (identified by experts in STEM education as highly successfully in preparing students underrepresented in STEM for STEM majors in college and future STEM careers) provides a rich description of the approach to ISHS school leadership by identifying various internal and external leadership factors influencing school leadership. This study examined an existing data set that included site visits to four ISHSs along with pre- and post-visit data, and a cross-case analysis focused on the leadership contributions of ISHS leaders and their larger community. This study found that the ISHSs expanded the concept of school leadership to include leadership both within and outside the school. In addition, school leaders needed autonomy to innovate and respond to their schools' needs. This included autonomy in hiring new teachers, autonomy from school district influence, and autonomy from restrictive teachers' union regulation and policies. Finally, ISHSs needed to continually invest in increasing their schools' capacities. This included investing in teacher professionalization, providing pathways for school leadership, collaborating with business and industry, and identifying the best student supports. A product of this study was a proposition for characterizing school leadership in an ISHS. This proposition may offer valuable insight, implications, and information for states and schools districts that may be planning or improving STEM education programs.

    Recently the need to manage food allergies in schools has been growing. This study aimed to examine the current status of managing food allergies in schools in Seoul, Korea. A questionnaire survey was conducted in cooperation with the School Dietician Association during April 2009. Among the participating 154 schools, a total of 109 (71%) were determining students' food allergy status through parental surveys based on self-reported food allergies. A total of 72 (47%) had experienced student visits to a school health room due to food allergies within one year before the survey. Over 80 percent of the schools relied on self-care only without any school-wide measures for food allergies in place. Among the 890 menu items most frequently served in school lunch programs, a total of 664 (75%) were found to contain more than one food allergen. It is highly suggested that preventive plans and treatment measures should be established to manage food allergies in schools.

  3. Oncology Education in Medical Schools: Towards an Approach that Reflects Australia's Health Care Needs.

    Science.gov (United States)

    McRae, Robert J

    2016-12-01

    Cancer has recently overtaken heart disease to become the number 1 cause of mortality both globally and in Australia. As such, adequate oncology education must be an integral component of medical school if students are to achieve learning outcomes that meet the needs of the population. The aim of this review is to evaluate the current state of undergraduate oncology education and identify how Australian medical schools can improve oncology learning outcomes for students and, by derivative, improve healthcare outcomes for Australians with cancer. The review shows that oncology is generally not well represented in medical school curricula, that few medical schools offer mandatory oncology or palliative care rotations, and that junior doctors are exhibiting declining oncology knowledge and skills. To address these issues, Australian medical schools should implement the Oncology Education Committee's Ideal Oncology Curriculum, enact mandatory oncology and palliative care clinical rotations for students, and in doing so, appreciate the importance of students' differing approaches to learning.

    Full Text Available This study examines the psychometric properties of two assessments of children’s approaches to learning: the Devereux Early Childhood Assessment (DECA and a 13-item approaches to learning rating scale (AtL derived from the Arizona Early Learning Standards (AELS. First, we administered questionnaires to 1,145 randomly selected parents/guardians of first-time kindergarteners. Second, we employed confirmatory factor analysis (CFA with parceling for DECA to reduce errors due to item specificity and prevent convergence difficulties when simultaneously estimating DECA and AtL models. Results indicated an overlap of 55% to 72% variance between the domains of the two instruments and suggested that the new AtL instrument is an easily administered alternative to the DECA for measuring children’s approaches to learning. This is one of the first studies that investigated DECA’s approaches to learning dimension and explored the measurement properties of an instrument purposely derived from a state’s early learning guidelines.

As the protective barrier of the CNS, the blood–brain barrier and the blood–cerebrospinal fluid barrier maintain the brain microenvironment, neuronal activity, and proper functioning of the CNS. Different strategies for efficient CNS delivery have been studied. This article reviews the current approaches to open or facilitate penetration across these barriers for enhanced drug delivery to the CNS. These approaches are summarized into three broad categories: noninvasive, invasive, and miscellaneous techniques. The progresses made using these approaches are reviewed, and the associated mechanisms and problems are discussed.

    Word finding difficulties frequently found in learners with language learning difficulties (Casby, 1992) are an integral part of Speech-Language Therapists' management role when working with learning disabled children. This study investigated current management for word finding difficulties by 70 Speech-Language Therapists in South African remedial schools. A descriptive survey design using a quantitative and qualitative approach was used. A questionnaire and follow-up focus group discussion were used to collect data. Results highlighted the use of the Renfrew Word Finding Scale (Renfrew, 1972, 1995) as the most frequently used formal assessment tool. Language sample analysis and discourse analysis were the most frequently used informal assessment procedures. Formal intervention programmes were generally not used. Phonetic, phonemic or phonological cueing were the most frequently used therapeutic strategies. The authors note strengths and raise concerns about current management for word finding difficulties in South African remedial schools, particularly in terms of bilingualism. Opportunities are highlighted regarding the development of assessment and intervention measures relevant to the diverse learning disabled population in South Africa.

  11. Current Perspectives on Desmoid Tumors: The Mayo Clinic Approach

    Directory of Open Access Journals (Sweden)

    Scott Okuno

    2011-08-01

    Full Text Available Desmoid tumors are a rare group of locally aggressive, non malignant tumors of fibroblastic origin that can lead to significant morbidity due to local invasion. Despite advances in the understanding of these tumors, their natural history is incompletely understood and the optimal treatment is still a matter of debate. Local control is the main goal of treatment and there has been a change in philosophy regarding the management of these tumors from aggressive surgical resection to function preservation. A multidisciplinary approach is essential to plan local control with acceptable morbidity. The current Mayo Clinic algorithm for the treatment of these tumors is based on institutional experience and the available evidence in the literature: asymptomatic/non progressive lesions away from vital structures are managed with observation and regular imaging; primary or recurrent desmoid tumors which are symptomatic or progressive or near vital structures are managed with wide surgical resection when wide surgical margins are possible with minimal functional and cosmetic loss. When positive or close surgical margins are likely, surgical resection with adjuvant radiotherapy or definitive radiotherapy is preferred. If likely functional or cosmetic deficit is unacceptable, radiotherapy is the treatment of choice. Unresectable lesions are considered for radiotherapy, chemotherapy or newer modalities however an unresectable lesion associated with a painful, functionless, infected extremity is managed with an amputation.

    2015-06-01

    Primary disorders of the gonad or those secondary to abnormalities of the hypothalamic pituitary axis result in hypogonadism. The range of health problems of childhood and adolescence that affect this axis has increased, as most children now survive chronic illness, but many have persisting deficits in gonadal function as a result of their underlying condition or its treatment. An integrated approach to hormone replacement is needed to optimize adult hormonal and bone health, and to offer opportunities for fertility induction and preservation that were not considered possible in the past. Timing of presentation ranges from birth, with disorders of sexual development, through adolescent pubertal failure, to adult fertility problems. This review addresses diagnosis and management of hypogonadism and focuses on new management strategies to address current concerns with fertility preservation. These include Turner syndrome, and fertility presevation prior to childhood cancer treatment. New strategies for male hormone replacement therapy that may impinge upon future fertility are emphasized. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2013-09-01

    Full Text Available Here is identified the tendency to reduce the effectiveness of anti-tobacco prevention work among graduating students of secondary school. This decline may be due to psychological and social reasons. It is shown that risk factors of involving in chemical dependency are meaningfully disclosed in longitudinal studies, whereas the dynamics of personal change during the formation of anti-addictive prevention skills are more fully disclosed in the comparative age sections. The typical phenomena, accompanying the downward trend in prevention, are the growth of problem behavior and the crisis of mass dropout. Such phenomena are so great that they are recognized as a crisis at a state level.

    Full Text Available Current data concerning features of multiple sclerosis (MS etiology, pathogenesis, clinical course and treatment of disease indicate the necessity of personalized approach to the management of MS patients. These features are the variety of possible etiological factors and mechanisms that trigger the development of MS, different courses of disease, and significant differences in treatment efficiency. Phenotypic and pathogenetic heterogeneity of MS requires, on the one hand, the stratification of patients into groups with different treatment depending on a number of criteria including genetic characteristics, disease course, stage of the pathological process, and forms of the disease. On the other hand, it requires the use of modern methods for assessment of individual risk of developing MS, its early diagnosis, evaluation and prognosis of the disease course and the treatment efficiency. This approach is based on the identification and determination of biomarkers of MS including the use of systems biology technology platforms such as genomics, proteomics, metabolomics and bioinformatics. Research and practical use of biomarkers of MS in clinical and laboratory practice requires the use of a wide range of modern medical and biological, mathematical and physicochemical methods. The group of "classical" methods used to study MS biomarkers includes physicochemical and immunological methods aimed at the selection and identification of single molecular biomarkers, as well as methods of molecular genetic analysis. This group of methods includes ELISA, western blotting, isoelectric focusing, immunohistochemical methods, flow cytometry, spectrophotometric and nephelometric methods. These techniques make it possible to carry out both qualitative and quantitative assay of molecular biomarkers. The group of "classical methods" can also include methods based on polymerase chain reaction (including multiplex and allele-specific PCR and genome sequencing

A total of 800 students from 4 urban and rural primary and secondary schools were randomly selected and investigated with questionnaires. The total awareness rate of malaria control knowledge was 61.27%, and the awareness rates of symptoms of malaria and malaria prevention were only 38.99% and 57.59% respectively. The main approach of obtaining the malaria control knowledge was media (51.52%). The univariate analysis showed that sex, area and different education levels affected the awareness rates of malaria control knowledge (P knowledge of country students was lower than that of urban students (P knowledge of the secondary school students was higher than that of the primary school students (P knowledge of primary and secondary school students in Yunlong District is lower than that required by the national standard. Therefore, the health education of malaria control should be strengthened, especially in countryside school students and primary school students.

    This study aims to investigate Grade 11 students' views on Science Technology Engineering Mathematics (STEM) with the integration of learning about electrical current based on Science Technology Society (STS) approach [8]. The participants were 60 Grade 11 students in Demonstration Secondary School, Khon Kaen University, Khon Kaen Province, Thailand. The methodology is in the respect of interpretive paradigm. The teaching and learning about Electrical Current through STS approach carried out over 6 weeks. The Electrical Current unit through STS approach was developed based on framework[8] that consists of five stages including (1) identification of social issues, (2) identification of potential solutions, (3) need for knowledge, (4) decision making, and (5) socialization stage. To start with, the question "what if this world is lack of electricity" was challenged in the class in order to move students to find the problem of how to design Electricity Generation from Clean Energy. Students were expected to apply scientific and other knowledge to design of Electricity Generation. Students' views on STEM were collected during their learning by participant' observation and students' tasks. Their views on STEM were categorized when they applied their knowledge for designing the Electricity Generation. The findings indicated that students cooperatively work to solve the problem when applying knowledge about the content of Science and Mathematics and processing skill of Technology and Engineering. It showed that students held the integration of science, technology, engineering and mathematics to design their possible solutions in learning about Electrical Current. The paper also discusses implications for science teaching and learning through STS in Thailand.

    . Available MELiSSA closed environment crop growth data were used to develop a first photosynthetic model representing the basic carbon fixation mechanisms. This model will be further elaborated in the course of this study to predict yield, oxygen production and transpi-ration. As an ultimate goal the model is intended to simulate the composition of the different plant organs (root, shoot, fruit/seed or tuber) for each crop under various conditions. For the validation of this model an extensive amount of data sets are needed. Current plant growth bench test setups will provide part of the required data. To gain more precise and detailed datasets, a highly closed plant growth chamber (Plant Characterization Unit, PCU) is under development. The PCU will provide accurate mass balances for carbon, water, oxygen and other elements with statistical reliability. This reliability is achieved through a high degree of closure and environment homogeneity. The PCU will also provide data for the above described plant characterization studies. The general work approach, the current status and future steps will be illustrated.

    South Africa (SA) implemented the Global Youth Tobacco Survey (GYTS) four times between 1999 and 2011. Data from the four surveys indicated that downward trends in cigarette use among students may have stalled. Understanding the effect of school anti-smoking education on current smoking among students within schools and variability across schools may provide important insights into policies aimed at preventing or reducing tobacco use among students. The objective was to assess the student- and school-level effects of students' exposure to school anti-smoking education on current cigarette use among the study population using the most recent wave of GYTS data in SA (2011). An analytic sample of students 13-15 years of age was selected (n=3,068) from the SA GYTS 2011. A taxonomy of two-level logistic regression models was fit to assess the relationship of various tobacco use, control, and exposure predictor variables on current cigarette smoking among the study population. At the student-level in the full model, secondhand smoke (SHS) exposure, peer smoking, and ownership of a promotional item were significantly associated with higher risk of current smoking. At the school-level in the full model, average exposure to peer smoking was associated with significant increases in the prevalence of current cigarette use, while average family anti-smoking education was significantly associated with decreases in the outcome variable. School anti-smoking education was not a statistically significant predictor at the student- or school-levels. in this study, exposure to school anti-smoking education had no association with current cigarette smoking among the study population. Consistent with previous studies, having peers that smoked was highly associated with a student being a current smoker. Interestingly, at the school-level in the multilevel analysis, schools with higher rates of average family anti-smoking education had lower prevalence of current smoking. This finding has

    2013-06-01

    Feedback is one of the most powerful tools, which teachers can use to enhance student learning. It appears difficult for teachers to give qualitatively good feedback, especially during active learning. In this context, teachers should provide facilitative feedback that is focused on the development of meta-cognition and social learning. The purpose of the present study is to contribute to the existing knowledge about feedback and to give directions to improve teacher feedback in the context of active learning. The participants comprised 32 teachers who practiced active learning in the domain of environmental studies in the sixth, seventh, or eighth grade of 13 Dutch primary schools. A total of 1,465 teacher-student interactions were examined. Video observations were made of active learning lessons in the domain of environmental studies. A category system was developed based on the literature and empirical data. Teacher-student interactions were assessed using this system. Results. About half of the teacher-student interactions contained feedback. This feedback was usually focused on the tasks that were being performed by the students and on the ways in which these tasks were processed. Only 5% of the feedback was explicitly related to a learning goal. In their feedback, the teachers were directing (rather than facilitating) the learning processes. During active learning, feedback on meta-cognition and social learning is important. Feedback should be explicitly related to learning goals. In practice, these kinds of feedback appear to be scarce. Therefore, giving feedback during active learning seems to be an important topic for teachers' professional development. © 2012 The British Psychological Society.

    The Contextual Teaching and Learning (CTL) approach is an approach involving active students in the learning process to discover the concepts learned through to knowledge and experience of the students. Similar to Piaget’s opinion that learning gives students an actives trying to do new things by relating their experiences and building their own minds. When students to connecting mathematics with real life, then students can looking between a conceptual to be learned with a concept that has been studied. So that, students can developing of mathematical connection ability. This research is quasi experiment with a primary school in the city of Kuningan. The result showed that CTL learning can be successful, when learning used a collaborative interaction with students, a high level of activity in the lesson, a connection to real-world contexts, and an integration of science content with other content and skill areas. Therefore, CTL learning can be applied by techer to mathematics learning in primary schools.

  17. New Approaches to Circulating Current Controllers for Modular Multilevel Converters

    Directory of Open Access Journals (Sweden)

    Miguel Moranchel

    2017-01-01

    Full Text Available In the next years, modular multilevel converters (MMCs are going to be a next generation multilevel converters for medium to high voltage conversion applications, such as medium voltage motor drives, medium voltage flexible AC transmission systems (FACTS and high voltage direct current transmission. They provide advantages such as high modularity, availability, low generation of harmonics, etc. However, the circulating current distorts the leg currents and increases the rated current of power devices, which further increases system cost. This paper focuses on analysis and suppression of these currents in a MMC using two algorithms for tracking of harmonics. For this work resonant controllers and repetitive controllers have been selected. Both controllers are analyzed and simulations results are presented. Moreover, the controllers have been tested and validated for a three phase MMC operating as an inverter using a real processing platform based on Zynq by Xilinx and designed to control large multilevel converters and in a real MMC prototype. These results are provided to demonstrate the feasibility of the proposed method.

    1986-01-01

    One of the more controversial issues in reimbursement policy is how to set the capital cost component of facilities rates. In this article we examine in detail the various approaches used by states to reimburse nursing homes for capital costs. We conclude that newer approaches that recognize the increasing value of nursing home assets over time, commonly called fair rental systems, are preferable to the methodologies that have been used historically in both the Medicare and the Medicaid programs to set capital rates. When properly designed, fair rental systems should provide more rational incentives and less encouragement of property manipulation than do more traditional systems, with little or no increase in state costs.

    Full Text Available Ankylosing spondylitis (AS is a chronic, inflammatory, rheumatic disease that mainly affects sacroiliac joints and spine. AS predominantly occurs more often in males and typically begins in the second or third decade. The mainstay of therapy in AS are nonsteroidal anti-inflammatory drugs, which reduce inflammation and pain. Disease modifying antirheumatic drugs (DMARD did not have enough evidence to prove their effect in AS treatment. The use of DMARD may not sufficient to improve the treatment and symptoms. Currently, TNF-blockers such as, Golimumab Etanersept Adalimumab İnfliksimab have promising results in the treatment of AS. TNF-blockers improve the clinical signs and symptoms, and improve the patients’ physical function and quality of life. This manuscript is focused that Current pharmacological treatments in patients with ankylosing spondylitis.

    To ensure safest possible operation and to get best overall economic performance of its Nuclear Power Plants, 10 years ago Electricite de France launched a Reliability Centered Maintenance (RCM) project to optimize the preventive maintenance programs. The principles underlying the RCM approach are based on common sense: failures must be prevented by preventive maintenance operations in all cases when the repercussions for the installation could be serious or critical in term of safety, availability or maintenance costs. The approach is a 3-phases process: 1. Evaluation of the functional consequences of failures 2. Evaluation of performances based on the analysis of experience feedback 3. Optimization of the preventive maintenance tasks The new preventive maintenance programs are presently almost completed and progressively implemented. Here and now, the implementation of the RCM approach allows to emphasize some benefits: 1. Same or increased level of safety 2. Same or increased level of plant availability 3. ALARA principles better taken into account 4. Cost control 5. Positive change in maintenance culture. Some new studies are in progress, such as the development of a 'Risk Based In Service Inspection' for passive components. (author)

  10. Treatment for spasmodic dysphonia: limitations of current approaches

    2009-01-01

    Purpose of review Although botulinum toxin injection is the gold standard for treatment of spasmodic dysphonia, surgical approaches aimed at providing long-term symptom control have been advancing over recent years. Recent findings When surgical approaches provide greater long-term benefits to symptom control, they also increase the initial period of side effects of breathiness and swallowing difficulties. However, recent analyses of quality-of-life questionnaires in patients undergoing regular injections of botulinum toxin demonstrate that a large proportion of patients have limited relief for relatively short periods due to early breathiness and loss-of-benefit before reinjection. Summary Most medical and surgical approaches to the treatment of spasmodic dysphonia have been aimed at denervation of the laryngeal muscles to block symptom expression in the voice, and have both adverse effects as well as treatment benefits. Research is needed to identify the central neuropathophysiology responsible for the laryngeal muscle spasms in order target treatment towards the central neurological abnormality responsible for producing symptoms.

    Frossard, Frédérique; Trifonova, Anna; Barajas Frutos, Mario

    The isolation of rural communities creates special necessities for teachers and students in rural schools. The present article describes "Rural Virtual School", a Virtual Community of Practice (VCoP) in which Spanish teachers of rural schools share learning resources and teaching methodologies through social software applications. The article arrives to an evolutionary model, in which the use of the social software tools evolves together with the needs and the activities of the VCoP through the different stages of its lifetime. Currently, the community has reached a high level of maturity and, in order to keep its momentum, the members intentionally use appropriate technologies specially designed to enhance rich innovative educational approaches, through which they collaboratively generate creative practices.

    2012-01-01

    Primary hypothyroidism is the most common endocrine disease. Although the diagnosis and treatment of hypothyroidism is often considered simple, there are large numbers of people with this condition who are suboptimally treated. Even in those people with hypothyroidism who are biochemically euthyroid on levothyroxine replacement there is a significant proportion who report poorer quality of life. This review explores the historical and current treatment options for hypothyroidism, reasons for and potential solutions to suboptimal treatment, and future possibilities in the treatment of hypothyroidism.

    2013-01-01

    Full Text Available The rate of cardiogenic embolism among all ischemic strokes is as high as 38%. Cardioembolic strokes are characterized by the higher magnitude of neurological deficit, the high risk of recurrent acute stroke, and a lethal outcome. This review deals with the etiopathogenesis of thrombus formation in the heart chambers, with current criteria for the verification of cardioembolic strokes, with the results of trials of new oral anticoagulants, and latest guidelines for antithrombotic therapy to prevent stroke. Special focus is given to secondary stroke prevention in patients with nonvalvular atrial fibrillation since it is atrial fibrillation that is the most common cause of cardioembolic stroke.

  14. Current approach for urinary system stone disease in pregnant women

    2016-01-01

    Full Text Available Urinary system stones can be classified according to size, location, X-ray characteristics, aetiology of formation, composition, and risk of recurrence. Especially urolithiasis during pregnancy is a diagnostic and therapeutic challenge. In most cases, it becomes symptomatic in the second or third trimester. Diagnostic options in pregnant women are limited due to the possible teratogenic, carcinogenic, and mutagenic risk of foetal radiation exposure. Clinical management of a pregnant urolithiasis patient is complex and demands close collaboration between patient, obstetrician and urologist. We would like to review current diagnosis and treatment modalities of stone disease of pregnant woman.

  15. Evaluating for impact: what type of data can assist a health promoting school approach?

    Science.gov (United States)

    Joyce, Andrew; Dabrowski, Anna; Aston, Ruth; Carey, Gemma

    2017-04-01

    There is debate within the health promoting school (HPS) movement on whether schools should monitor health behaviour outcomes as part of an evaluation or rely more on process type measures, such as changes to school policies and the physical and social environment which yield information about (in)effective implementation. The debate is often framed around ideological considerations of the role of schools and there is little empirical work on how these indicators of effective implementation can influence change at a policy and practice level in real world settings. Information has potentially powerful effects in motivating a change process, but this will vary according to the type of information and the type of organizational culture into which it is presented. The current predominant model relies on process data, policy and environmental audit monitoring and benchmarking approaches, and there is little evidence of whether this engages school communities. Theoretical assertions on the importance of monitoring data to motivate change need to be empirically tested and, in doing so, we can learn which types of data influence adoption of HPS in which types of school and policy contexts. © The Author 2016.

    2015-01-01

    Opinion Statement Family-based behavioral intervention has been demonstrated to be an effective and safe treatment for childhood obesity and should be considered a first-line treatment option. However, access to such intensive evidence-based treatment is limited and, currently, obesity care is dominated by high intensity behavioral treatment implemented in specialty clinics or less effective, low intensity treatments implemented in primary care. However, capitalizing on the established and ongoing relationship between primary care providers and families, primary care providers hold an invaluable role in early identification of overweight and obesity, and subsequent referral to an evidence-based treatment. key aspects of effective treatment include: early intervention, moderate- to high-intensity intervention of sufficient duration, multi-component intervention targeting dietary modification, physical activity and behavioral strategies, family involvement and goals targeting family members, and follow-up contact during maintenance. The purpose of this review is to present the current empirically supported treatment options for pediatric obesity including primary care-based interventions and diagnostic tools, multi-component behavioral intervention with a focus on family-based behavioral intervention, immersion treatment, and pharmacologic and surgical management.

  19. Current concepts and future approaches to vestibular rehabilitation.

    Science.gov (United States)

    Tjernström, Fredrik; Zur, Oz; Jahn, Klaus

    2016-04-01

    Over the last decades methods of vestibular rehabilitation to enhance adaptation to vestibular loss, habituation to changing sensory conditions, and sensory reweighting in the compensation process have been developed. However, the use of these techniques still depends to a large part on the educational background of the therapist. Individualized assessment of deficits and specific therapeutic programs for different disorders are sparse. Currently, vestibular rehabilitation is often used in an unspecific way in dizzy patients irrespective of the clinical findings. When predicting the future of vestibular rehabilitation, it is tempting to foretell advances in technology for assessment and treatment only, but the current intense exchange between clinicians and basic scientists also predicts advances in truly understanding the complex interactions between the peripheral senses and central adaptation mechanisms. More research is needed to develop reliable techniques to measure sensory dependence and to learn how this knowledge can be best used--by playing off the patient's sensory strength or working on the weakness. To be able using the emerging concepts, the neuro-otological community must strive to educate physicians, physiotherapists and nurses to perform the correct examinations for assessment of individual deficits and to look for factors that might impede rehabilitation.

    Marzi, Andrea; Feldmann, Heinz

    2016-01-01

    Ebola hemorrhagic fever is one of the most fatal viral diseases worldwide affecting humans and nonhuman primates. Although infections only occur frequently in Central Africa, the virus has the potential to spread globally and is classified as a category A pathogen that could be misused as a bioterrorism agent. As of today there is no vaccine or treatment licensed to counteract Ebola virus infections. DNA, subunit and several viral vector approaches, replicating and non-replicating, have been tested as potential vaccine platforms and their protective efficacy has been evaluated in nonhuman primate models for Ebola virus infections, which closely resemble disease progression in humans. Though these vaccine platforms seem to confer protection through different mechanisms, several of them are efficacious against lethal disease in nonhuman primates attesting that vaccination against Ebola virus infections is feasible.

    2002-04-01

    Our aim was to emphasize the role of endoscopic detorsion in the treatment of sigmoid colon volvulus, which we currently apply in the majority of our cases. The data of 37 patients were analyzed in a retrospective manner, during a 86-month period, between May 1994 and July 2001. The patients were classified into three groups. The first group consisted of 9 patients with resection and anastomosis, the second group consisted of 20 patients with Hartmann's procedure, and the third group consisted of 8 patients with endoscopic detorsion. Complications were encountered in 7 patients (19%), and 3 patients (8%) died following treatment. We favor colonic resection following endoscopic treatment. Resection should be preferred, if endoscopic detorsion is not successful or in the presence of a complication.

    2009-10-01

    We compared the content of the cardiac screening questions on US state high school athletic association preparticipation evaluation forms with current consensus recommendations. We reviewed the high school athletic association's approved, recommended, or required sports preparticipation form from each of the 50 US states and the District of Columbia, and compared the content of the personal and family history components with current recommendations for cardiac screening questions. We found that 85% of the preparticipation forms in current use contain all elements of the formerly recommended guidelines, but only 17% contain all elements of the new consensus guidelines. We conclude that although there appears to be some improvement in the content of the preparticipation forms in current use compared with previous studies, the vast majority of these forms are incomplete compared with current consensus guidelines.

    As current dengue control strategies have been shown to be largely ineffective in reducing dengue in school-aged children, novel approaches towards dengue control need to be studied. Insecticide-impregnated school uniforms represent an innovative approach with the theoretical potential to reduce dengue infections in school children. This study took place in the context of a randomised control trial (RCT) to test the effectiveness of permethrin-impregnated school uniforms (ISUs) for dengue prevention in Chachoengsao Province, Thailand. The objective was to assess the acceptability of ISUs among parents, teachers, and principals of school children involved in the trial. Quantitative and qualitative tools were used in a mixed methods approach. Class-clustered randomised samples of school children enrolled in the RCT were selected and their parents completed 321 self-administered questionnaires. Descriptive statistics and logistic regression were used to analyse the quantitative data. Focus group discussions and individual semi-structured interviews were conducted with parents, teachers, and principals. Qualitative data analysis involved content analysis with coding and thematic development. The knowledge and experience of dengue was substantial. The acceptability of ISUs was high. Parents (87.3%; 95% CI 82.9-90.8) would allow their child to wear an ISU and 59.9% (95% CI 53.7-65.9) of parents would incur additional costs for an ISU over a normal uniform. This was significantly associated with the total monthly income of a household and the educational level of the respondent. Parents (62.5%; 95% CI 56.6-68.1) indicated they would be willing to recommend ISUs to other parents. Acceptability of the novel tool of ISUs was high as defined by the lack of concern along with the willingness to pay and recommend. Considering issues of effectiveness and scalability, assessing acceptability of ISUs over time is recommended.

    2016-04-01

    Full Text Available Currently, teachers in the UK learn about behaviour management strategies from theoretical perspectives when training, through discussions with mentors, and by trial and error at their schools. Existing literature mainly focuses on such issues from the ‘adult’ viewpoint, not the voice of the child. This paper reports on work-in-progress developing a range of Augmented Reality (AR resources for these issues, drawing upon co-design research workshops with children from a Year 6 class (aged 10 in a UK Primary School. Our research informs approaches to classroom management by encouraging reflection and analysis of ‘critical incidents’ identified by the pupils, and explored by teachers in workshops through the medium of AR, giving a reality previously uncaptured in more traditional approaches.

    2018-06-01

    The Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs) including polycythemia vera, essential thrombocythemia and primary myelofibrosis are clonal hematological malignancies that originate at the level of the hematopoietic stem cell, and are characterized by excessive proliferation of cells belonging to one or more of the myeloid lineages. Central to the pathogenesis of the MPNs is constitutive activation of the JAK/STAT signaling pathway due to a family of driver mutations affecting JAK2, CALR or MPL. These disorders share common clinical and laboratory features, a significant burden of systemic symptoms, increased risk of developing arterial and venous thrombotic events, and the potential to progress to myelofibrosis and acute leukemia. Areas covered: We identified four clinical situations which represent challenging management dilemmas for patients with MPNs. Our conclusions and recommendations are based on a literature search using MEDLINE and recent meeting abstracts using the keywords, focusing on publications directly addressing these scenarios and on recent contributions to the field. Expert commentary: Multi-center efforts to study large cohorts of MPN patients have led to more uniform and evidence-based approaches to key aspects in MPN management. However, treatment strategies to deal with specific clinical scenarios are lacking.

    Pasic, Ivan; Lipton, Jeffrey H

    2017-04-01

    Of all the cancers, chronic myeloid leukaemia (CML) has witnessed the most rapid evolution of the therapeutic milieu in recent decades. The introduction of tyrosine kinase inhibitors (TKIs) as a therapeutic option has profoundly changed patient experience and outcome. The availability of multiple new highly effective therapies has increasingly underscored the importance of a good understanding of the underlying pathophysiological basis in CML, as well as patient-specific factors in choosing the right treatment for every individual. The treatment of CML has migrated in many jurisdictions from the office of a highly specialized malignant hematologist to the general hematologist or even a general practitioner. The goal of this review is to offer an overview of the modern approach to the treatment of CML, with an emphasis on chronic phase (CP) CML, including both TKI-based therapies such as imatinib, dasatinib, nilotinib, bosutinib and ponatinib, and non-TKI medications, such as omacetaxine. We discuss evidence behind each drug, most common and material adverse reactions and outline how this information can be used in selecting the right drug for the right patient. We also discuss evidence as it relates to other therapies, including stem cell transplant (SCT), and patients in accelerated (AP) and blastic phase (BP). Copyright © 2017 Elsevier Ltd.

    2017-01-01

    Full Text Available The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5 replaces the term «dementia» with «major neurocognitive disorder» (MNCD, which can reduce the  stigmatization of patients and focus the attention of specialists on  the preserved abilities of patients rather than deficit symptoms. In  the next 35 years, the number of patients with MNCD in the world is  predicted to almost triple. The article considers the concept,  epidemiology, and etiological pattern of this syndrome. It  characterizes in detail Alzheimer's disease (AD that is a cause of  MNCD in 50–70% of cases. The current diagnostic criteria and  clinical presentations of the disease are given. The presence of early and significant episodic memory disorders as both alone or  concurrent with other cognitive and behavioral changes reflects the  main clinical phenotype of AD. Magnetic resonance morphometry,  amyloid positron emission tomography, and estimation of  cerebrospinal fluid β-amyloid and tau protein levels find increasing  applications in research and routine practice. Drug and non-drug  treatments for MNCD are considered. The use of akatinol memantine to treat this disorder and the issues related to the comprehensive management of patients with severe cognitive impairment are analyzed.

    Melanoma is the most aggressive and deadly type of skin cancer. Surgical resection with or without lymph node sampling is the standard of care for primary cutaneous melanoma. Adjuvant therapy decisions may be informed by careful consideration of prognostic factors. High-dose adjuvant interferon alpha-2b increases disease-free survival and may modestly improve overall survival. Less toxic alternatives for adjuvant therapy are currently under study. External beam radiation therapy is an option for nodal beds where the risk of local recurrence is very high. In-transit melanoma metastases may be treated locally with surgery, immunotherapy, radiation, or heated limb perfusion. For metastatic melanoma, the options include chemotherapy or immunotherapy; targeted anti-BRAF and anti-KIT therapy is under active investigation. Standard chemotherapy yields objective tumor responses in approximately 10%–20% of patients, and sustained remissions are uncommon. Immunotherapy with high-dose interleukin-2 yields objective tumor responses in a minority of patients; however, some of these responses may be durable. Identification of activating mutations of BRAF, NRAS, c-KIT, and GNAQ in distinct clinical subtypes of melanoma suggest that these are molecularly distinct. Emerging data from clinical trials suggest that substantial improvements in the standard of care for melanoma may be possible

    To alert physician to timely recognition and current treatment of recurrent hypopyon iridocyclitis or panuveitis in ocular Behçet disease (OBD). Interferon-α, rituximab, intravitreal triamcinolone, and biological response modifiers by tumor necrosis factor inhibitors such as infliximab and adalimumab are being used increasingly for the treatment of severe sight-threatening ocular inflammation including retinal vasculitis and cystoid macular edema (CME). Biological agents offer tremendous potential in the treatment of OBD. Given that OBD predominantly afflicts the younger adults in their most productive years, dermatologist, rheumatologist, internist, or general practitioners supervising patients with oculo-articulo-oromucocutaneous syndromes should be aware of systemic Behçet disease. Early recognition of ocular involvement is important and such patients should strongly be instructed to visit immediately an ophthalmologist, as uveitis management differs from extraocular involvements with high ocular morbidity from sight-threatening complications due to relapsing inflammatory attacks in the posterior segment of the eye. A single infliximab infusion should be considered for the control of acute panuveitis, whereas repeated long-term infliximab infusions were proved to be more effective in reducing the number of episodes in refractory uveoretinitis with faster regression and complete remission of CME.

    2017-08-01

    Idiopathic pulmonary fibrosis (IPF) is a progressive and ultimately fatal lung disease associated with dyspnoea, cough and impaired quality of life. Currently, the aims of patient care are to improve outcomes for patients by slowing the progression of the disease, extending life, and improving quality of life. A prompt, accurate diagnosis is important to enable patients to receive treatment early in the course of the disease and to be considered for lung transplantation. Two anti-fibrotic drugs, nintedanib and pirfenidone, have been shown to reduce decline in lung function in patients with IPF. In addition to pharmacological therapy, optimal management of IPF includes treatment of comorbidities, symptom relief, pulmonary rehabilitation, and palliative care. Patient education is important to enable patients to make decisions about their care and to help them manage their disease and the side-effects of anti-fibrotic drugs. Research continues into new treatments and combinations of treatments that may improve outcomes for patients with this devastating disease. Copyright © 2017. Published by Elsevier Ltd.

    Full Text Available Despite the great popularity of autism among researchers, its main cause still remains unknown. However, there are many theories which describe the mechanisms of this disorder. On the other hand, one who tries to integrate them seems to be helpless according to their contradictory and – in most cases – hypothetical status. In a context of this inac‑ curacy, focusing only on one of the concepts would be probably very disadvantageous. As many researchers suggest, the etiology of autism is complex and it is the interaction of multiple factors which implies the disorder appears. It seems that the nature of autism is equifinal and heterogeneous. Thus, the aim of this article is to present a review of current biological theories of autism etiology and to indicate the environmental as well as innate risk factors which may disturb the natural pathway of child development: prenatal (which increase the probability of autism emergence as early as in the first or second year of life or perinatal ones (low birth weight, hypoxia, age of the mother, her educational sta‑ tus. The foetal testosterone theory of autism and its general consequences for the child development will be described also. Finally, the neurological, neurochemical and neuroanatomical dysfunctions in autism will be presented.

    2010-02-01

    Pancreaticoduodenal injuries are uncommon owing to the protected position of the pancreas and duodenum in the retroperitoneum. Management depends on the extent of injury. This study was undertaken to document outcome of pancreaticoduodenal injuries and to re-evaluate our approach. A prospective study of all patients treated for pancreaticoduodenal trauma in one surgical ward at King Edward VIII hospital over a 7-year period (1998 - 2004). Demographic data, clinical presentation, findings at laparotomy and outcome were documented. Prophylactic antibiotics were given at induction of anaesthesia. A total of 488 patients underwent laparotomy over this period, 43 (9%) of whom (all males) had pancreatic and duodenal injuries. Injury mechanisms were gunshot (30), stabbing (10) and blunt trauma (3). Their mean age was 30.1+9.6 years. Delay before laparotomy was 12.8+29.1 hours. Seven were admitted in shock. Mean Injury Severity Score (ISS) was 14+8.6. Management of 20 duodenal injuries was primary repair (14), repair and pyloric exclusion (3) and conservative (3). Management of 15 pancreatic injuries was drainage alone (13), conservative management of pseudocyst (1) and distal pancreatectomy (1). Management of 8 combined pancreaticoduodenal injuries was primary duodenal repair and pancreatic drainage (5) and repair with pyloric exclusion of duodenal injury and pancreatic drainage (3). Twenty-one patients (49%) developed complications, and 28 required ICU admission with a median ICU stay of 4 days. Ten patients died (23%). Mean hospital stay was 18.3+24.4 days. The overall mortality was comparable with that in the world literature. We still recommend adequate exploration of the pancreas and duodenum and conservative operative management where possible.

    To evaluate the current provision and outcome of community-based education (CBE) in UK medical schools. An online survey of UK medical school websites and course prospectuses and a systematic review of articles from PubMed and Web of Science were conducted. Articles in the systematic review were assessed using Rossi, Lipsey and Freeman's approach to programme evaluation. Publications from November 1998 to 2013 containing information related to community teaching in undergraduate medical courses were included. Out of the 32 undergraduate UK medical schools, one was excluded due to the lack of course specifications available online. Analysis of the remaining 31 medical schools showed that a variety of CBE models are utilised in medical schools across the UK. Twenty-eight medical schools (90.3%) provide CBE in some form by the end of the first year of undergraduate training, and 29 medical schools (93.5%) by the end of the second year. From the 1378 references identified, 29 papers met the inclusion criteria for assessment. It was found that CBE mostly provided advantages to students as well as other participants, including GP tutors and patients. However, there were a few concerns regarding the lack of GP tutors' knowledge in specialty areas, the negative impact that CBE may have on the delivery of health service in education settings and the cost of CBE. Despite the wide variations in implementation, community teaching was found to be mostly beneficial. To ensure the relevance of CBE for 'Tomorrow's Doctors', a national framework should be established, and solutions sought to reduce the impact of the challenges within CBE. This is the first study to review how community-based education is currently provided throughout Medical Schools in the UK. The use of Rossi, Lipsey and Freeman's method of programme evaluation means that the literature was analysed in a consistent and comprehensive way. However, a weakness is that data from the online survey was obtained from

    2016-03-01

    Full Text Available Introduction. Cough is one of the most common symptoms in the practice of doctors of various specialties, including pediatricians. Cough treatment should be started with the identification of its cause and correct diagnosis. Most often, cough in children is due to the increased viscosity of bronchial secretions, i.e. violation of sputum transport in the bronchial tree, and insufficient activity of ciliated epithelium. The main objective of the treatment of productive cough is dilution of sputum, bronchial secretion and excretion, thus necessitating the administration of mucolytics. Currently, one of the most famous mucolytics is acetylcysteine, cysteine amino acid product, such as ACC®. However, today the question of ACC® (acetylcysteine application in infants and young children is still debatable. This article presents a study whose objective was to evaluate the therapeutic efficacy and tolerability of ACC® (20 mg/ml solution in the treatment of bronchopulmonary diseases in children aged 2 to 6 years. Materials and methods. The study involved 60 children with acute tracheitis, simple bronchitis, acute obstructive bronchitis, recurrent bronchitis in the acute phase, community-acquired pneumonia, asthma exacerbation, cystic fibrosis. Patients of the main groups (n = 40 received ACC® (20 mg/ml solution at the age-specific dosage 3 times a day in combined treatment. Therapy of patients in the control group (n = 20 was conducted without ACC®. Results. During follow-up, patients who received ACC® had significant positive changes in the nature of cough, sputum viscosity and its amount as opposed to a comparison group of patients. Complete disappearance of cough was achieved on day 5–8 from the beginning of treatment, while in the control group patients, this time was longer. The evaluation of the effectiveness of the study drug showed that very good efficacy was achieved in 75 % of patients and good — in 20 %, and among patients who

    Bolden, Shenell L. T.

    The purpose of this exploratory study was to examine key stakeholders' perceptions of the current Baltimore City Public Schools' (BCPS) sex education curriculum and to gain insight into how they believe the curriculum could be modified to be more effective. A mixed methods approach using qualitative and quantitative data collection consisting of a survey, focus group interview, and individual interviews was conducted to gather information on stakeholders' perceptions. The stakeholders included: (1) former students who received their sex education courses in the Baltimore City Public School system (BCPS); (2) teachers in BCPS who were affiliated with the sex education curriculum; (3) health care professionals who screened and/or treated East Baltimore City residents for a sexually transmitted disease (STD) and; (4) one policy maker who was responsible for creating sex education curriculum at the national level. Analysis of the quantitative data from former Baltimore City Public School students revealed a general satisfaction with the current sex education curriculum. However, qualitative data from the same group of stakeholders revealed several changes they thought should be implemented into the program in an effort to improve the current curriculum. Findings from the other groups after qualitative analysis of the interviews suggest three major themes in support of curriculum change: (1) a blended curriculum that integrates both the cognitive and affective learning domains; (2) knowledge of prevention of STD's and pregnancy; and (3) authentic teaching and learning. Results from this study strongly suggest that the Baltimore City Public School system is apathetic to the sexual health needs of students and, therefore, is inadvertently contributing to the high rate of sexually transmitted diseases among young people. Keywords: Abstinence, Affective domain, Indoctrination, Behavior Modification, Cognitive domain, Sex education curriculum, Sexually Transmitted Diseases.

  7. An Investigation of Turkish Middle School Science Teachers' Pedagogical Orientations Towards Direct and Inquiry Instructional Approaches

    Science.gov (United States)

    Sahingoz, Selcuk

    One of the most important goals of science education is preparing effective science teachers which includes the development of a science pedagogical orientation. Helping in-service science teachers improve their orientations toward science teaching begins with identifying their current orientations. While there are many aspects of an effective science teaching orientation, this study specifically focuses on effective pedagogy. The interest of this study is to clarify pedagogical orientations of middle school science teachers in Turkey toward the teaching of science conceptual knowledge. It focuses on what instructional preferences Turkish middle school science teachers have in theory and practice. The purpose of this study is twofold: 1) to elucidate teacher pedagogical profiles toward direct and inquiry instructional approaches. For this purpose, quantitative profile data, using a Turkish version of the Pedagogy of Science Teaching Test (POSTT-TR) assessment instrument, was collected from 533 Turkish middle school science teachers; 2) to identify teaching orientations of middle school science teachers and to identify their reasons for preferring specific instructional practices. For this purpose, descriptive qualitative, interview data was collected from 23 teachers attending a middle school science teacher workshop in addition to quantitative data using the POSTT-TR. These teachers sat for interviews structured by items from the POSTT-TR. Thus, the research design is mixed-method. The design provides a background profile on teacher orientations along with insights on reasons for pedagogical choices. The findings indicate that instructional preference distributions for the large group and smaller group are similar; however, the smaller workshop group is more in favor of inquiry instructional approaches. The findings also indicate that Turkish middle school science teachers appear to have variety of teaching orientations and they have varied reasons. Moreover, the

  9. NATURAL SCIENCE AT SCHOOL: MODERN APPROACHES TO THE DIFFERENTIATED STUDY

    Directory of Open Access Journals (Sweden)

    Dechtyarenko S.G.

    2015-08-01

    Full Text Available The article analyzes the possibility of differentiated study natural science at school on the basis of ecological educational process. Natural science is the science about nature as a single unity or totality of the natural sciences, which constituting a single unit. The main aim of the course is to develop student’s natural science competence through integrated mastering system knowledge about nature and man, the basics of environmental knowledge, ways of improving teaching and learning activities, development of value orientations in relation to the nature. There is strong need to review approaches to teaching nature science at schools, taking into account the general trend of greening of the educational process. The aim of the work is to analyze the possibility of practical application of modern approaches to differentiated teaching of the nature science at school greening within the educational process. In our view, the environmental component may be a basis to the formation and differentiated teaching in general. The environmental component of the educational sector has been aimed to the student’s environmental consciousness and compliance with rules of environmentally safe behavior in the environment. The learning of the integrated knowledge about nature and man can be submitted through the prism of action of the environmental factors according classic approach to their classification: abiotic, biotic and anthropogenic factors. In parallel, it is reasonable to raise the issues of practical importance as some natural objects and actions of each of these factors. The new degree of the studying of the environment has been provided by the beginning of the systematization of knowledge about natural objects and structure of the universe, by the formation of primary concepts about the relationship between the world of the living and inanimate nature, between organisms and between human activities and changes that has been occurred in the

    Demharter, Timo; Michel, Ulrich

    2012-10-01

    From a didactic point of view the procurement and the application of modern geographical methods and functions become more and more important. Although the integration of GIS in the classroom is repeatedly demanded, inter alia in Baden-Württemberg, Germany, the number of GIS users is small in comparison to other European countries or the USA. Possible reasons for this could, for instance, lie in the lack of GIS and computer knowledge of the teachers themselves and the subsequent extensive training effort in Desktop-GIS (KERSKI 2000, SCHLEICHER 2004). Today you have the technological possibilities to provide the broad public with geoinformation and geotechnology: Web technologies offer access to web-based, mobile and local applications through simple gateways. The objective of the project "GIS4schools" is to generate a service-based infrastructure, which can be operated via mobile clients as well as via Desktop-GIS or a Browser. Due to the easy availability of the services the focus is in particular on students. This circumstance is a novelty through which a differentiated approach to the implementation of GIS in schools is established. Accordingly, the pilot nature of this project becomes apparent as well as its greater importance beyond its actual content especially for the sector of media development at colleges of education. The continuity from Web-GIS to Desktop-GIS is innovative: The goal is to create an adapted multi-level solution which allows both, an easy introduction if desired or a detailed analysis - either to be achieved with a focus especially on students and their cooperation among one another.

    Graham, Bruce S; Knight, G William; Graham, Linda

    2016-01-01

    Cheating incidents in 2006-07 led U.S. dental schools to heighten their efforts to enhance the environment of academic integrity in their institutions. The aims of this study were to document the measures being used by U.S. dental schools to discourage student cheating, determine the current incidence of reported cheating, and make recommendations for enhancing a culture of integrity in dental education. In late 2014-early 2015, an online survey was distributed to academic deans of all 61 accredited U.S. dental schools that had four classes of dental students enrolled; 50 (82%) responded. Among measures used, 98% of respondents reported having policy statements regarding student academic integrity, 92% had an Honor Code, 96% provided student orientation to integrity policies, and most used proctoring of final exams (91%) and tests (93%). Regarding disciplinary processes, 27% reported their faculty members only rarely reported suspected cheating (though required in 76% of the schools), and 40% disseminated anonymous results of disciplinary hearings. A smaller number of schools (n=36) responded to the question about student cheating than to other questions; those results suggested that reported cheating had increased almost threefold since 1998. The authors recommend that schools add cheating case scenarios to professional ethics curricula; disseminate outcomes of cheating enforcement actions; have students sign a statement attesting to compliance with academic integrity policies at every testing activity; add curricular content on correct writing techniques to avoid plagiarism; require faculty to distribute retired test items; acquire examination-authoring software programs to enable faculty to generate new multiple-choice items and different versions of the same multiple-choice tests; avoid take-home exams when assessing independent student knowledge; and utilize student assessment methods directly relevant to clinical practice.

    Prospects for equipment of present-day school with computing machinery allow fresh approaches to be applied to the improvement of means for diagnosis and health prophylaxis in children and to professional orientation. Automatic systems have been developed for diagnosing diseases and monitoring the sociomental health of children and the adaptation of junior and middle schoolchildren to school activities. The systems provide a real way of successfully following the development of major mental functions for prenosological diagnosis of detected abnormalities and their subsequent correction. An automatic system for professional orientation of middle- and senior-form pupils has been devised on the basis of mental diagnostic testing of the schoolchildren's professional orientation, interests, inclinations, psychophysiological and personality traits.

  3. Historical approach of contemporary understanding of school in globalization

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Intercultural education respects and promotes diversity in all areas of human life. This phenomenon indicates that people naturally and spontaneously develop different lifestyles, different customs and worldviews. These differences need to be considered as a wealth of life. When we talk about education, and school as a narrow concept, in which the differences are usually promoted, we have a vision of a community that provides equal opportunities, opposes injustice and discrimination, and strives for the values which equality is being built on. Especially, this phenomenon is being pointed out in our conditions, when we are still adapting to the reforms of globalization. In the Contemporary World, promoting the democracy becomes a key goal of education, as well as the whole society. Therefore, in the education system it should be taken into account the multicultural character of the society that tends to actively contribute to a peaceful coexistence and positive interaction between different cultural groups. Traditionally, in this sense, there are two approaches in education: multi­cultural education that strives to provide the acceptance and tolerance of other cultures through learning about them. On the other side, we have the intercultural education that aims to overcome the passive coexistence and achieve developed and sustainable way of living together in a multicultural society. This is achieved through the construcive process of understanding, mutual respect and dialogue among groups of different cultures, then, ensuring equal opportunities and combating discrimination.

    Full Text Available Wai Tong Chien, Annie LK Yip School of Nursing, Faculty of Health and Social Sciences, The Hong Kong Polytechnic University, Hung Hom, Kowloon, Hong Kong Abstract: During the last three decades, an increasing understanding of the etiology, psychopathology, and clinical manifestations of schizophrenia spectrum disorders, in addition to the introduction of second-generation antipsychotics, has optimized the potential for recovery from the illness. Continued development of various models of psychosocial intervention promotes the goal of schizophrenia treatment from one of symptom control and social adaptation to an optimal restoration of functioning and/or recovery. However, it is still questionable whether these new treatment approaches can address the patients' needs for treatment and services and contribute to better patient outcomes. This article provides an overview of different treatment approaches currently used in schizophrenia spectrum disorders to address complex health problems and a wide range of abnormalities and impairments resulting from the illness. There are different treatment strategies and targets for patients at different stages of the illness, ranging from prophylactic antipsychotics and cognitive–behavioral therapy in the premorbid stage to various psychosocial interventions in addition to antipsychotics for relapse prevention and rehabilitation in the later stages of the illness. The use of antipsychotics alone as the main treatment modality may be limited not only in being unable to tackle the frequently occurring negative symptoms and cognitive impairments but also in producing a wide variety of adverse effects to the body or organ functioning. Because of varied pharmacokinetics and treatment responsiveness across agents, the medication regimen should be determined on an individual basis to ensure an optimal effect in its long-term use. This review also highlights that the recent practice guidelines and standards have

    Background Many adult cigarette smokers initiated the habit as adolescents. Adolescent tobacco use may be a marker of other unhealthy behaviours. There are limited data on the prevalence and correlates of cigarette smoking among in-school adolescents in Iraq. We aimed to estimate the prevalence of, and assess the socio-demographic correlates of current cigarette smoking among in-school adolescents in Kurdistan region of Iraq. Methods Secondary data analysis of the Global Youth Tobacco Survey, conducted in the region of Kurdistan, Iraq in 2006. Logistic regression analysis was conducted to assess the association between current cigarette smoking and explanatory variables. Results One thousand nine hundred eighty-nine adolescents participated in the Kurdistan-Iraq Global Youth Tobacco Survey. Of these, 58.1% and 41.9% were boys and girls respectively. The overall prevalence of current cigarette smoking was 15.3%; 25.1% and 2.7% in boys and girls respectively. The factors associated with adolescent smoking were: parents' smoking, smoking in closest friends, male gender, having pocket money and perceptions that boys or girls who smoked were attractive. Conclusion We suggest that public health interventions aimed to curb adolescent cigarette smoking should be designed, implemented and evaluated with due recognition to the factors that are associated with the habit.

    To conduct a systematic assessment of library and informatics training at accredited Western U.S. medical schools. To provide a structured description of core practices, detect trends through comparisons across institutions, and to identify innovative training approaches at the medical schools. Action research study pursued through three phases. The first phase used inductive analysis on reported library and informatics skills training via publicly-facing websites at accredited medical schools and the academic health sciences libraries serving those medical schools. Phase Two consisted of a survey of the librarians who provide this training to undergraduate medical education students at the Western U.S. medical schools. The survey revealed gaps in forming a complete picture of current practices, thereby generating additional questions that were answered through the Phase Three in-depth interviews. Publicly-facing websites reviewed in Phase One offered uneven information about library and informatics training at Western U.S. medical schools. The Phase Two survey resulted in a 77% response rate. The survey produced a clearer picture of current practices of library and informatics training. The survey also determined the readiness of medical students to pass certain aspects of the United States Medical Licensure Exam. Most librarians interacted with medical school curricular leaders through either curricula committees or through individual contacts. Librarians averaged three (3) interventions for training within the four-year curricula with greatest emphasis upon the first and third years. Library/informatics training was integrated fully into the respective curricula in almost all cases. Most training involved active learning approaches, specifically within Problem-Based Learning or Evidence-Based Medicine contexts. The Phase Three interviews revealed that librarians are engaged with the medical schools' curricular leaders, they are respected for their knowledge and

  17. The cognitivist approach to the development of functional thinking of junior elementary school students

    2015-01-01

    Full Text Available The paper deals with the cognitivist approach to the development of functional thinking from the period of preschool and early school age. Some recent scientific results on the capacity of child's brain undoubtedly indicate the fact that the experience that children receive on a daily basis, the way they receive and respond to the outside impressions and the stimuli to which they react shape their brain and influence the development of their general personality. A continuous fight for dominance takes place among the brain neurons, the result of which is creation the new connections between active neurons and new brain controls. The principal intention of the author is to stress the importance of a correct approach to an early-age development at the point of which the most intense development of the brain cells takes place and the paths for the total development of personality are traced out. Therefore, what happens to a child in this period is consequential for further development. The goal of this work is to stress that total cognitive development is conditioned by the development thinking at an early age. Therefore, the way we stimulate the child's functional thinking at an early pre-school age is extremely important and requires a more serious approach. Logical tasks and problem-solving situations are of special importance for the development of logical cognitive structures. The child's natural and social environments stimulate several sensory cooperative activities and increase the impact on perception, thus increasing a number of synapses. A methodological approach to activities to result in a functional thinking of children at an early age should be developed in such a way as to satisfy some higher demands than is the case with the current ones, i.e. it should stimulate children's further cognitive development.

  20. Promoting physical activity among children and adolescents: the strengths and limitations of school-based approaches.

    Booth, Michael; Okely, Anthony

    2005-04-01

    Paediatric overweight and obesity is recognised as one of Australia's most significant health problems and effective approaches to increasing physical activity and reducing energy consumption are being sought urgently. Every potential approach and setting should be subjected to critical review in an attempt to maximise the impact of policy and program initiatives. This paper identifies the strengths and limitations of schools as a setting for promoting physical activity. The strengths are: most children and adolescents attend school; most young people are likely to see teachers as credible sources of information; schools provide access to the facilities, infrastructure and support required for physical activity; and schools are the workplace of skilled educators. Potential limitations are: those students who like school the least are the most likely to engage in health-compromising behaviours and the least likely to be influenced by school-based programs; there are about 20 more hours per week available for physical activity outside schools hours than during school hours; enormous demands are already being made on schools; many primary school teachers have low levels of perceived competence in teaching physical education and fundamental movement skills; and opportunities for being active at school may not be consistent with how and when students prefer to be active.

    Full Text Available Over the last decades, an impressive number of conceptual models in the field of educational leadership have emerged; contingency or trait theories, situational, instructional, shared or distributed school leadership approaches, all tried to demonstrate their specific impact on school development and students achievement. The present paper is focused on exploring one of the foremost models, subject of systematic inquiry and controversial debates developed in relation with school or in nonschool organizations: transformational school leadership. The approach is considered a relevant support for school change process. Its contribution is analyzed in comparison with the benefits of other competing models, the aim of the paper being not to establish hierarchies but to gather significant solutions for better schooling. As a reconciliation solution, the integrative leadership model is also advocated.

    2007-01-01

    We report a study of spin-dependent transport in a system composed of a quantum dot coupled to a normal metal lead and a ferromagnetic lead NM-QD-FM. We use the master equation approach to calculate the spin-resolved currents in the presence of an external bias and an intradot Coulomb interaction....... We find that for a range of positive external biases current flow from the normal metal to the ferromagnet the current polarization =I↑−I↓ / I↑+I↓ is suppressed to zero, while for the corresponding negative biases current flow from the ferromagnet to the normal metal attains a relative maximum value....... The system thus operates as a rectifier for spin-current polarization. This effect follows from an interplay between Coulomb interaction and nonequilibrium spin accumulation in the dot. In the parameter range considered, we also show that the above results can be obtained via nonequilibrium Green functions...

    Full Text Available Abstract Background Alcohol drinking is frequently related to behavioral problems, which lead to a number of negative consequences. This study was to evaluate the characteristics of male high school students who drink, the drinking patterns among them, and the associations between current drinking and other health risk behaviors which focused on personal safety, violence-related behaviors, suicide and sexual behaviors. Method A cross-sectional study was conducted to explore current alcohol drinking and health-risk behaviors among male high school students in central Thailand. Five thousand one hundred and eighty four male students were classified into 2 groups according to drinking in the previous 30 days (yes = 631, no = 4,553. Data were collected by self-administered, anonymous questionnaire which consisted of 3 parts: socio-demographic factors, health-risk behaviors and alcohol drinking behavior during the past year from December 2007 to February 2008. Results The results showed that the percent of current drinking was 12.17. Most of them were 15-17 years (50.21%. Socio-demographic factors such as age, educational level, residence, cohabitants, grade point average (GPA, having a part time job and having family members with alcohol/drug problems were significantly associated with alcohol drinking (p Conclusions An increased risk of health-risk behaviors, including driving vehicles after drinking, violence-related behaviors, sad feelings and attempted suicide, and sexual behaviors was higher among drinking students that led to significant health problems. Effective intervention strategies (such as a campaign mentioning the adverse health effects and social consequences to the risk groups, and encouraging parental and community efforts to prevent drinking among adolescents should be implemented to prevent underage drinking and adverse consequences.

    2009-01-01

    The system of radiological protection of the environment that is currently under development is one contribution to the general need to adequately protect the environment against stress. Dominated by operational goals, it emphasizes conceptual and methodological approaches that are readily accessible today: reference organisms supported by individual-based traditional ecotoxicological data. Whilst there are immediate advantages to this approach (pragmatism, consistency with other approaches in use for man and biota), there are also clear limitations, especially in a longer run perspective, that need to be acknowledged and further considered. One can mention a few: uncertainties generated by the need for various extrapolations (from lower to higher levels of biological organisation, ...), various features missed such as potential ecological impact through impairment of ecosystem processes, trans-generational impacts as mediated through genomic instability, indirect effects mediated through trophic interactions or disruption of ecological balances, ... Such limitations have already been faced in other fields of environmental protection against other stressors, pushing a number of environment professionals to assign stronger emphasis on more systemic approaches. This review discusses the advantages and limitations of the current approach designed for the radiological protection of non-human biota in the broader context of environment protection as a whole, with especial reference to upcoming trends and evolutions. This leads in particular to advocating the need to boost scientific and methodological approaches featuring the ecosystem concept as a mean to access a unified goal of protection: preserving life sustainability through protection of ecosystem structure and functioning.

    In the emerging debate around obesity intervention in schools, recent calls have been made for researchers to include local community opinions in the design of interventions. Community-based participatory research (CBPR) is an effective approach for forming community partnerships and integrating local opinions. We used CBPR principles to conduct formative research in identifying acceptable and potentially sustainable obesity intervention strategies in 8 New Mexico school communities. We collected formative data from 8 high schools on areas of community interest for school health improvement through collaboration with local School Health Advisory Councils (SHACs) and interviews with students and parents. A survey based on formative results was created to assess acceptability of specific intervention strategies and was provided to SHACs. Quantitative data were analyzed using descriptive statistics while qualitative data were evaluated using an iterative analytic process for thematic identification. Key themes identified through the formative process included lack of healthy food options, infrequent curricular/extracurricular physical activity opportunities, and inadequate exposure to health/nutritional information. Key strategies identified as most acceptable by SHAC members included healthier food options and preparation, a healthy foods marketing campaign, yearly taste tests, an after-school noncompetitive physical activity program, and community linkages to physical activity opportunities. An adaptive CBPR approach for formative assessment can be used to identify obesity intervention strategies that address community school health concerns. Eight high school SHACs identified 6 school-based strategies to address parental and student concerns related to obesity. © 2012, American School Health Association.

    2015-08-01

    Full Text Available This article discusses the results of a study of actual mental state of high school students who are active subjects of career self-determination in terms of interactive learning. There are four groups of methods of interactive training: psychological training, art therapy, cognitive, and game training. The main task, which is solved by a researcher in a formative experiment with the use of each of these methods, is to establish significant differences in health, activity and mood as the indicators of current mental state of students in the classroom. As a result, we found that the most significant improvements in the current mental state takes place when using art and game therapy, so these techniques should be used in groups of students with low motivation to work, as well as in the adverse psychological climate. Less significant was the improvement of the current mental state after psychological training due to the fact that this method allow to update and seek solutions to the most important intrapersonal issues and require the implementation of a deeper reflection

  1. A Phase Current Reconstruction Approach for Three-Phase Permanent-Magnet Synchronous Motor Drive

    Directory of Open Access Journals (Sweden)

    2016-10-01

    Full Text Available Three-phase permanent-magnet synchronous motors (PMSMs are widely used in renewable energy applications such as wind power generation, tidal energy and electric vehicles owing to their merits such as high efficiency, high precision and high reliability. To reduce the cost and volume of the drive system, techniques of reconstructing three-phase current using a single current sensor have been reported for three-phase alternating current (AC control system using the power converts. In existing studies, the reconstruction precision is largely influenced by reconstructing dead zones on the Space Vector Pulse Width Modulation (SVPWM plane, which requires other algorithms to compensate either by modifying PWM modulation or by phase-shifting of the PWM signal. In this paper, a novel extended phase current reconstruction approach for PMSM drive is proposed. Six novel installation positions are obtained by analyzing the sampling results of the current paths between each two power switches. By arranging the single current sensor at these positions, the single current sensor is sampled during zero voltage vectors (ZVV without modifying the PWM signals. This proposed method can reconstruct the three-phase currents without any complex algorithms and is available in the sector boundary region and low modulation region. Finally, this method is validated by experiments.

    2018-01-01

    Full Text Available School nutrition policies provide promising avenues towards the improvement of children’s eating habits and the prevention of obesity. Childhood obesity rates and related chronic diseases are increasing in Queensland, in part as a result of unhealthy eating habits and lack of physical activity. There is a very high investment by the Queensland government in maintaining healthy weight and promoting nutrition and physical activity among schoolchildren through delivering a range of initiatives across the state. However, there is a lack of evidence concerning the effectiveness of nutrition/physical education and parental involvement programs addressing obesity delivered in Queensland schools. This paper can be used to guide government and policy-makers regarding the most effective policy options that will promote healthy eating and physical activity among Queensland schoolchildren. The aim of this paper is to: (i summarize current evidence on Queensland government responses to obesity; and (ii discuss potential policy options that could support healthy eating and regular physical activity, and examine the evidence base for each option and suggest new areas for future research.

    2015-05-01

    Full Text Available From 2006 to 2014, the Ministry of Public Education of Costa Rica implemented four strategic actions to reduce high school dropout rates. The main purpose of these actions was to promote student participation and student identification with their school. Studies prepared by the Ministry of Education and the Comptroller of the Republic were revised to assess the impact of these actions. The result of these actions does not show an actual decrease in the number of students who leave high school. Therefore, a more holistic view is necessary to ensure the students’ stay. This review suggests using use the concept of student engagement and applying a three tier system-wide dropout preventive actions: universal, targeted and intensive.

    Agricultural biotechnology is being rapidly adopted as evidenced by the acreage of genetically modified (GM) crops planted and tonnes of product (grain and fiber) harvested. Concurrent with this technological progress, is a growing concern that the worlds biological diversity is coming under increasing threat from human activities. As such, ecological risk assessment approaches are being developed for GM crop plants as international agreements regulating the transboundary movements of these products are being implemented. This paper reviews the ecological risk assessment approach that has been used to date to approve GM crops to date. The process has been case-by-case, using a comparative, science-based approach balancing the potential risks and benefits of the new technology versus those present with the currently accepted practices. The approach used to evaluate and approve these products is consistent with the conditions and requirements outlined in the Cartagena Protocol.

    Full Text Available The textbooks are the main teaching tool for students and teachers. The analysis of these books enables point out several shortcomings in relation to the contents approach. Thus, the objective of this work was to analyze the approach to the Atlantic Forest, considered one of the most degraded environments of the world. A total of seven high school biology textbooks were analyzed, following an evaluation script with general information, biotic and abiotic factors, environmental conservation and anthropic action, which were considered as satisfactory or unsatisfactory in the textbooks evaluation. In general, the Atlantic Forest theme has been addressed by all assessed books, including specific topics, however, some aspects such as the use of images was made improperly, leading to misunderstandings about Atlantic forest. In addition, ecosystem dynamics, its components and the environmental impacts have not been addressed satisfactorily in the majority of the works assessed. In general, the theme Atlantic Forest has been addressed by all assessed books, including specific topics, however, many aspects of this theme presented problems in their approach: update, concepts, definitions and importance, and also presented problems in their illustration of the current situation of Atlantic Forest. Periodic revisions of these textbooks are of great importance to assure student formation that allows them to analyze and know the effects of their actions on the environment and to reflect on ways to alleviates them.

    Many challenging plasma control problems still need to be addressed in order for the ITER Plasma Control System (PCS) to be able to successfully achieve the ITER project goals. For instance, setting up a suitable toroidal current density profile is key for one possible advanced scenario characterized by noninductive sustainment of the plasma current and steady-state operation. The nonlinearity and high dimensionality exhibited by the plasma demand a model-based current-profile control synthesis procedure that can accommodate this complexity through embedding the known physics within the design. The development of a model capturing the dynamics of the plasma relevant for control design enables not only the design of feedback controllers for regulation or tracking but also the design of optimal feedforward controllers for a systematic model-based approach to scenario planning, the design of state estimators for a reliable real-time reconstruction of the plasma internal profiles based on limited and noisy diagnostics, and the development of a fast predictive simulation code for closed-loop performance evaluation before implementation. Progress towards control-oriented modeling of the current profile evolution and associated control design has been reported following both data-driven and first-principles-driven approaches. An overview of these two approaches will be provided, as well as a discussion on research needs associated with each one of the model applications described above.

    Murai, Kenji

    2013-01-01

    In 2008, a new guideline about radioactivity was added to the government guidelines for teaching junior high school science. Since then people involved with school education have been trying to spread correct information about radioactivity. On the other hand, people's confusion in the aftermath of the Fukushima Daiichi Nuclear Power Plant accident has clearly shown that people do not know much about radioactivity. Considering the situation, the author conducted an investigation about the current state of radiation education and carried out an opinion survey about radioactivity among adults. The investigation about education showed the following: (1) the nature of radiation, such as its permeability, and its uses were described in the government-approved textbooks; (2) basic knowledge, such as what are radiation effects, were described comprehensively in the supplementary reading recommendations made by the Ministry of Education, Culture, Sports, Science, and Technology; and (3) locale education committees created teaching materials such as guidance to present topics. The opinion survey had questions to judge: (1) current public understanding of radioactivity; (2) the degree of general information that people collected for themselves; (3) the degree of specific knowledge about radioactivity that people had; and (4) people's attitudes toward various problems with radioactivity in the environment. The results suggested that for radiation education the following items are important: (1) to learn that radioactivity exists in people's daily lives and is used safely in various field; (2) to get basic knowledge and better quantitative understanding of such things as radioactivity units, radiation dose and radiation effects; and (3) to acquire practical experience to use the information effectively.

  8. Evaluation of health promotion in schools: a realistic evaluation approach using mixed methods

    Science.gov (United States)

    2010-01-01

    Background Schools are key settings for health promotion (HP) but the development of suitable approaches for evaluating HP in schools is still a major topic of discussion. This article presents a research protocol of a program developed to evaluate HP. After reviewing HP evaluation issues, the various possible approaches are analyzed and the importance of a realistic evaluation framework and a mixed methods (MM) design are demonstrated. Methods/Design The design is based on a systemic approach to evaluation, taking into account the mechanisms, context and outcomes, as defined in realistic evaluation, adjusted to our own French context using an MM approach. The characteristics of the design are illustrated through the evaluation of a nationwide HP program in French primary schools designed to enhance children's social, emotional and physical health by improving teachers' HP practices and promoting a healthy school environment. An embedded MM design is used in which a qualitative data set plays a supportive, secondary role in a study based primarily on a different quantitative data set. The way the qualitative and quantitative approaches are combined through the entire evaluation framework is detailed. Discussion This study is a contribution towards the development of suitable approaches for evaluating HP programs in schools. The systemic approach of the evaluation carried out in this research is appropriate since it takes account of the limitations of traditional evaluation approaches and considers suggestions made by the HP research community.

  9. Incorporating Science News Into Middle School Curricula: Current Events in the 21st Century Classroom

    2010-12-01

    Middle school students are instructed with the aid of textbooks, lectures, and activities to teach topics that satisfy state standards. However, teaching materials created to convey standard-aligned science concepts often leave students asking how the content relates to their lives and why they should be learning it. Conveying relevance, especially in science when abstract concepts can often be incorrectly perceived as irrelevant, is important for student learning and retention. One way to create an educational link between classroom content and everyday life is through the use of scientific current events. Students read, hear, and watch media coverage of natural events (such as the Haiti or Chile earthquakes in 2010), but do not necessarily relate the scientific information from media sources to classroom studies. Taking advantage of these brief ‘teachable moments’-when student interest is high- provides a valuable opportunity to make classroom-to-everyday life associations and to incorporate inquiry based learning. To address this need, we are creating pre-packaged current event materials for middle school teachers in Arizona that align to state standards and which are short, effective, and easy to implement in the classroom. Each lesson takes approximately 15 minutes to implement, allowing teachers time to facilitate brief but meaningful discussions. Materials are assembled within approximately one week of the regional or global science event (e.g., volcanic eruptions, earthquakes) and may include a short slide show, maps, videos, pictures, and real-time data. A listserv is used to send biweekly emails to subscribed instructors. The email contains the current event topic, specific Arizona science standards addressed, and a link to download the materials. All materials are hosted on the Arizona State University Education Outreach website and are archived. Early implementation efforts have been received positively by participating teachers.

    Full Text Available Leaving school has far reaching consequences both for the individual and the society. We tackled this problem by using Bronfenbrenner's ecological systems theory to analyse case studies of 12 children (elementary and secondary schools who quit schooling or are under risk to do so. It is an adequate frame of reference for understanding the causes of school-leaving since it considers different levels of development and their relations. The children and four parents took part in semi-structured interviews. Other data were gathered by interviewing the focus groups of school principals, school pedagogues and psychologists, teachers, Parent Councils, and pupils. The qualitative analysis shows a disturbed structure and functioning even at the level of microsystem (family, school, peers which may be linked with school-leaving. The relations between microsystems are sporadic and inadequate (mesosystem which additionally stimulates school-leaving. Higher levels of environment (exo and macro systems in which children do not participate, yet depend upon their indirect influence, stimulate school leaving, too. Many children were faced with nonnormative life events (chrono-system: divorce or death of parent/s, underage pregnancy, family moving. We view this research as the initial step which will identify the problems and lead to future directions of research which would, based on Bronfenbrenner's approach, systematically examine different levels of environment and form the basis for creating ecologically valid measures for prevention of school-leaving.

  3. Are Current Accounts of Asian Economies Mean-reverting?: Nonlinear Unit Root Test Approach

    Directory of Open Access Journals (Sweden)

    Bonghan Kim

    2005-12-01

    Full Text Available This paper tests the mean reverting property of current account in the financial crisis-affected 5 counties of southeast Asia using nonlinear unit root tests of Park and shintani(2004. Our approach is based on the idea that a conventional unit root test has lower power in detecting the nonlinear mean reverting behavior if the current account follows a nonlinear mean reversion process. We obtained following empirical results. First, for the pre-crisis period (1981Q1-1996Q4, the current accounts of Indonesia, Malaysia and Philippines are mean-reverting but those of Korea and Thailand are not mean-reverting. Second, for the full sample period (1981Q1-2003Q4, the ADF test fails to reject the unit root of the current account in all countries except Philippines. However, unit root is rejected in favor of nonlinear mean reversion except Thailand. This nonlinear unit root test result implies that crisis-affected Asian countries except Thailand have sustainable paths of current accounts. Third, when the current accounts of East Asian countries are nonlinear mean-reverting, the mean reverting process can be well described by the ESTAR model, instead of the DTAR or DLSTAR model. The nonlinear unit root test results imply smooth nonlinear mean-reversion behaviors of East Asian current accounts. Finally, the shape of estimated impulse response functions becomes steeper as the size of shock increases, which is the very characteristic of the nonlinear process.

  4. Light-cone gauge approach to arbitrary spin fields, currents and shadows

    International Nuclear Information System (INIS)

    Metsaev, R R

    2014-01-01

    Totally symmetric arbitrary spin fields in AdS space, conformal fields, conformal currents, and shadow fields in flat space are studied. Light-cone gauge formulations for such fields, currents and shadows are obtained. Use of the Poincaré parametrization of AdS space and ladder operators allows us to treat fields in flat and AdS spaces on an equal footing. Light-cone gauge realization of relativistic symmetries for fields, currents and shadows is also obtained. The light-cone gauge formulation for fields is obtained by using the gauge invariant Lagrangian which is presented in terms of modified de Donder divergence, while the light-cone gauge formulation for currents and shadows is obtained by using the gauge invariant approach to currents and shadows. This allows us to demonstrate explicitly how the ladder operators entering the gauge invariant formulation of fields, currents and shadows manifest themselves in the light-cone gauge formulation for fields, currents and shadows.

  12. Pharmacological modulations of cardiac ultra-rapid and slowly activating delayed rectifier currents: potential antiarrhythmic approaches.

    Science.gov (United States)

    Islam, Mohammed A

    2010-01-01

    Despite the emerging new insights into our understandings of the cellular mechanisms underlying cardiac arrhythmia, medical therapy for this disease remains unsatisfactory. Atrial fibrillation (AF), the most prevalent arrhythmia, is responsible for significant morbidity and mortality. On the other hand, ventricular fibrillation results in sudden cardiac deaths in many instances. Prolongation of cardiac action potential (AP) is a proven principle of antiarrhythmic therapy. Class III antiarrhythmic agents prolong AP and QT interval by blocking rapidly activating delayed rectifier current (I(Kr)). However, I(Kr) blocking drugs carry the risk of life-threatening proarrhythmia. Recently, modulation of atrial-selective ultra-rapid delayed rectifier current (I(Kur)), has emerged as a novel therapeutic approach to treat AF. A number of I(Kur) blockers are being evaluated for the treatment of AF. The inhibition of slowly activating delayed rectifier current (I(Ks)) has also been proposed as an effective and safer antiarrhythmic approach because of its distinguishing characteristics that differ in remarkable ways from other selective class III agents. Selective I(Ks) block may prolong AP duration (APD) at rapid rates without leading to proarrhythmia. This article reviews the pathophysiological roles of I(Kur) and I(Ks) in cardiac repolarization and the implications of newly developed I(Kur) and I(Ks) blocking agents as promising antiarrhythmic approaches. Several recent patents pertinent to antiarrhythmic drug development have been discussed. Further research will be required to evaluate the efficacy and safety of these agents in the clinical setting.

  13. Auroral Substorms: Search for Processes Causing the Expansion Phase in Terms of the Electric Current Approach

    Science.gov (United States)

    Akasofu, Syun-Ichi

    2017-10-01

    Auroral substorms are mostly manifestations of dissipative processes of electromagnetic energy. Thus, we consider a sequence of processes consisting of the power supply (dynamo), transmission (currents/circuits) and dissipations (auroral substorms-the end product), namely the electric current line approach. This work confirms quantitatively that after accumulating magnetic energy during the growth phase, the magnetosphere unloads the stored magnetic energy impulsively in order to stabilize itself. This work is based on our result that substorms are caused by two current systems, the directly driven (DD) current system and the unloading system (UL). The most crucial finding in this work is the identification of the UL (unloading) current system which is responsible for the expansion phase. A very tentative sequence of the processes leading to the expansion phase (the generation of the UL current system) is suggested for future discussions. (1) The solar wind-magnetosphere dynamo enhances significantly the plasma sheet current when its power is increased above 10^{18} erg/s (10^{11} w). (2) The magnetosphere accumulates magnetic energy during the growth phase, because the ionosphere cannot dissipate the increasing power because of a low conductivity. As a result, the magnetosphere is inflated, accumulating magnetic energy. (3) When the power reaches 3-5× 10^{18} erg/s (3-5× 10^{11} w) for about one hour and the stored magnetic energy reaches 3-5×10^{22} ergs (10^{15} J), the magnetosphere begins to develop perturbations caused by current instabilities (the current density {≈}3× 10^{-12} A/cm2 and the total current {≈}106 A at 6 Re). As a result, the plasma sheet current is reduced. (4) The magnetosphere is thus deflated. The current reduction causes partial B/partial t > 0 in the main body of the magnetosphere, producing an earthward electric field. As it is transmitted to the ionosphere, it becomes equatorward-directed electric field which drives both

  14. High School Girls’ Everyday Aesthetics on Instagram: The Affordance Approach

    Directory of Open Access Journals (Sweden)

    Jou-Chun Su

    2018-04-01

    Full Text Available This study explores high school girls’ Instagram aesthetic practices based on the affordance theory. We conduct in-depth interviews and photo analyses of 10 subjects to reveal how these girls interact with the app’s interface, and what strategic practices they have developed to interact with the affordances preset by Instagram. The findings demonstrate that Instagram has become a realm for everyday aesthetics due to its design priority on photos. These high school girls navigate in plural art worlds as they share their reframed photos with a variety of social groups, of which each has its own discrete aesthetic convention. This indicates that Instagram’s interface design has successfully associated itself with taste and beauty, eliciting these girls to collect more reframing apps in order to achieve their own distinction. As a result, aesthetics takes shape in everyday life, but they take their own aestheticized life as the real one.

    Directory of Open Access Journals (Sweden)

    Galyna Shapoval

    2017-09-01

    Full Text Available In modern conditions of management, the value of an enterprise becomes the main indicator, which is learned not only by scientists, but also by owners of enterprise and potential investors. Current assets take a very important place among the factors that affect the value of an enterprise, so management of current assets becomes more acute from the point of their impact on enterprise value. The purpose of the paper is to develop a system of value-based management of corporate construction companies’ current assets. The main tasks are: the study of current assets impact on the value of corporate construction companies, the definition of value-based approach to managing current assets of corporate enterprises and development of value-based management system of corporate construction companies’ current assets by elements. General scientific and special research methods were used while writing the work. Value-based management of current assets involves value-based management of the elements of current assets. The value-based inventory management includes the following stages of management: the assessment of reliability and choice of supplier according to the criterion of cash flow maximization, the classification of stocks in management accounting according to the rhythm of supply and the establishment of periodicity of supplies in accordance with the needs of the construction process. The value-based management of accounts receivable includes the following stages of management: assessment of the efficiency of investment of working capital into accounts receivable, the assessment of customers' loyalty and the definition of credit conditions and monitoring of receivables by construction and debt instruments. Value-based cash management involves determining the required level of cash to ensure the continuity of the construction process, assessing the effectiveness of cash use according to the criterion of maximizing cash flow, as well as budget

    Ramos, Nestor R.; Mo, Clifton C.; Karp, Judith E.; Hourigan, Christopher S.

    2015-01-01

    The limited sensitivity of the historical treatment response criteria for acute myeloid leukemia (AML) has resulted in a different paradigm for treatment compared with most other cancers presenting with widely disseminated disease. Initial cytotoxic induction chemotherapy is often able to reduce tumor burden to a level sufficient to meet the current criteria for “complete” remission. Nevertheless, most AML patients ultimately die from their disease, most commonly as clinically evident relapsed AML. Despite a variety of available salvage therapy options, prognosis in patients with relapsed or refractory AML is generally poor. In this review, we outline the commonly utilized salvage cytotoxic therapy interventions and then highlight novel investigational efforts currently in clinical trials using both pathway-targeted agents and immunotherapy based approaches. We conclude that there is no current standard of care for adult relapsed or refractory AML other than offering referral to an appropriate clinical trial. PMID:25932335

    Highlights: → Passive battery-ultracapacitor hybrids are examined. → Frequency domain analysis is employed. → The ultracapacitor branch operates as a low-pass filter for the battery. → The battery supplies the average load demand. → Design requirements are discussed. - Abstract: A Fourier-based analysis of passive battery-ultracapacitor hybrid sources is introduced in the manuscript. The approach is first introduced for a general load, and then is followed by a study for a case of periodic pulsed current load. It is shown that the ultracapacitor branch is perceived by the battery as a low-pass filter, which absorbs the majority of the high frequency harmonic current and letting the battery to supply the average load demand in addition to the small part of dynamic current. Design requirements influence on the ultracapacitor capacitance and internal resistance choice are quantitatively discussed. The theory is enforced by simulation and experimental results, showing an excellent agreement.

    The State Space modelling approach has been recently proposed as an engineering-driven technique for part quality prediction in Multistage Machining Processes (MMP). Current State Space models incorporate fixture and datum variations in the multi-stage variation propagation, without explicitly considering common operation variations such as machine-tool thermal distortions, cutting-tool wear, cutting-tool deflections, etc. This paper shows the limitations of the current State Space model through an experimental case study where the effect of the spindle thermal expansion, cutting-tool flank wear and locator errors are introduced. The paper also discusses the extension of the current State Space model to include operation variations and its potential benefits.

    2011-03-01

    The Battle River Project (BRP) is a school division-level intervention in rural Alberta, Canada, built upon the health-promoting schools approach to health promotion. Using self-reported school and student-level data from administrators and students, the central aim of the BRP is to examine: 'How can the school environment and health behaviours (healthy eating, physical activity and mental wellness) of children and youth be improved when a health-promoting schools model, the Ever Active Schools program, is implemented with school division support?' Evidence used to inform school level changes included students' demographic, behavioral, and psychosocial variables linked to school environment data, comprised of school demographics and administrator-assessed quality of policies, facilities, and programs related to physical activity. Each participating school and the division were provided with a tailored report of their schools' results to reflect, plan and implement for positive health behavior change. The main lesson learned was that sharing school-specific evidence can operate as a catalyst for embedding health promoting policy and practices within the school and division culture.

    McManic, Janet A.

    The purpose of this study was to investigate students' perceptions of motivation to achieve while participating in general level high school biology classes. In a national poll of teacher's attitudes, student's motivation was a top concern of teachers (Elam, 1989). The student's perceptions of motivation are important to understand if improvements and advancements in motivation are to be implemented in the science classroom. This qualitative study was conducted in an urban high school that is located in a major metropolitan area in the southeast of the United States. The student body of 1100 is composed of Caucasian, African-American, Hispanic, and Asian students. The focus question of the study was: What are students' perceptions of their motivation in biology class? From general level biology classes, purposeful sampling narrowed the participants to fifteen students. Semi-structured interviews were conducted with the participants having varying measurements of motivation on the Scale of Intrinsic versus Extrinsic Orientation in the Classroom (Harter, 1980). The interviews were recorded and transcribed. After transcription, the interviews were coded by the constant comparative method (Glaser & Strauss, 1967). The coded data of students' responses were analyzed and compared to current theories of motivation. The current theories are the social-cognitive model (Bandura, 1977), attribution theory (Weiner, 1979), basic needs theory (Maslow, 1954) and choice theory (Glasser, 1986). The results of this study support the social cognitive model of motivation (Bandura, 1977) through the description of family structure and its relationship to motivation (Gonzalez, 2002). The study upheld previous research in that extrinsic orientation was shown to be prevalent in older students (Harter, 1981; Anderman & Maehr, 1994). In addition, the students' responses disclosed the difficulties encountered in studying biology. Students expressed the opinion that biology terms are

    Past research studies have focused on perceptions of stuttering by various age groups and only a few have examined how children react to a peer who stutters. All of these studies used a quantitative analysis but only one included a qualitative analysis of elementary school age children's responses to stuttering. The aim of this study was to further explore the perceptions of elementary school students toward a peer who stutters using both quantitative and qualitative analyses of three levels of stuttering. Participants included 88 elementary school children between 8 and 12 years of age. Each participant viewed one of four audiovisual samples of a peer producing fluent speech and mild, moderate, and severe simulated stuttering. Each participant then rated five Likert statements and answered three open-ended questions. Quantitative and qualitative results indicated that negative ratings and the percentage of negative comments increased as the frequency of stuttering increased. However, the children in this study indicated that they were comfortable listening to stuttering and would be comfortable making friends with the peer who stutters. The findings of this study together with past research in this area should help clinicians and their clients appreciate the range of social and emotional reactions peers have of a child who stutters. After reading this article, the reader will be able to: (a) discuss past research regarding children's perceptions of stuttering; (b) summarize the need to explore the perceptions of elementary-aged children toward a peer who stutters; (c) describe the major quantitative and qualitative findings of children's perceptions of stuttering; and (d) discuss the need for disseminating more information about stuttering to children and teachers.

    In a world of shrinking habitats and increasing competition for natural resources, potentially dangerous predators bring the challenges of coexisting with wildlife sharply into focus. Through interdisciplinary collaboration among authors trained in the humanities, social sciences, and natural sciences, we reviewed current approaches to mitigating adverse human-predator encounters and devised a vision for future approaches to understanding and mitigating such encounters. Limitations to current approaches to mitigation include too much focus on negative impacts; oversimplified equating of levels of damage with levels of conflict; and unsuccessful technical fixes resulting from failure to engage locals, address hidden costs, or understand cultural (nonscientific) explanations of the causality of attacks. An emerging interdisciplinary literature suggests that to better frame and successfully mitigate negative human-predator relations conservation professionals need to consider dispensing with conflict as the dominant framework for thinking about human-predator encounters; work out what conflicts are really about (they may be human-human conflicts); unravel the historical contexts of particular conflicts; and explore different cultural ways of thinking about animals. The idea of cosmopolitan natures may help conservation professionals think more clearly about human-predator relations in both local and global context. These new perspectives for future research practice include a recommendation for focused interdisciplinary research and the use of new approaches, including human-animal geography, multispecies ethnography, and approaches from the environmental humanities notably environmental history. Managers should think carefully about how they engage with local cultural beliefs about wildlife, work with all parties to agree on what constitutes good evidence, develop processes and methods to mitigate conflicts, and decide how to monitor and evaluate these.

    Full Text Available During the last few years, East-Europeans, predominantly Romanians, have become the second largest cultural minority in Catalonia (Spain. Spanish educational institutions now have students from more than twenty different cultures. This paper focuses on the educational background and the factors which characterize the educational experience of Romanian students prior to attending schools in Spain, and how this affects their experiences into Catalonian primary schools. Twenty seven interviews were undertaken, of Catalonian and Romanian teachers, of experts and parents from the host primary schools where the proportion of Romanian students was highest. Two focus-group sessions were carried out with school teachers from Romania. The analysis shows that there is some consistency between educational practices and values in Romania and the practices and values of the host schools. The ability of children to assimilate into the host school is directly influenced by their previous experience in the schools in their country of origin.

    Taiwan launched its evidence-based health-promoting school (HPS) program via an action-research approach in 2010. The program featured a collaborative partnership between schools, local education authorities and university support networks. This study was focused on examining whether an HPS action-research approach was effective in advancing HPS implementation, perceived HPS impact and perceived HPS efficacy in Taiwan. In 2011, questionnaires were sent to 900 sample schools in Taiwan. A total of 621 schools returned the questionnaire, including 488 primary schools and 133 middle schools. The response rate was 69%. This study compared the difference in HPS implementation status, perceived HPS impact and perceived HPS efficacy between those schools that had implemented action-research HPS (138 schools) and those that had not (483 schools). The univariate analysis results indicated that the HPS implementation levels for components that included school health policies, physical environment, social environment, teaching activities and school-community relations were significantly higher in action-research schools than in non-action-research schools. Teachers in action-research schools reported significantly higher levels of HPS impact and HPS efficacy than non-action-research schools. The multivariate analysis results indicated that after controlling for school level and HPS funding, the HPS action-research approach was significantly positively related to greater levels of HPS implementation, perceived HPS impact and perceived HPS efficacy.

    Full Text Available The term sustainability is important for the comprehension of how Environmental Education and practices of Permaculture can be used as tools of education. Permaculture is characterized as a system for planning and creation, in a harmonic manner, of productive, sustainable and ecologic environments. The goal of this paper is to evaluate permaculture’s practices efficiency as a tool of environmental education and mechanism of integration between the human being and the environment. The project was developed in a school of municipal education system located in the rural part of Ituiutaba, State of Minas Gerais, involving 40 people directly. Students and staff participated taking to school plants that are part of their everyday life, in other words, that have cultural value for their community. The integration between students, staff and the remaining residents was noticed mainly when everyone got involved in developing the vegetable garden, showing the aggregating potential through joint actions that such activities allow. The unity and estimation of one’s own living place bring the feeling of belonging and the improvement of ambiance, important aspects for the improvement of people’s, that live far from urban centers, life quality.

    Full Text Available Using stories in teaching foreign language, it forces the teacher to be crative and innovative to encourage the young learners to enjoy reading stories. The teacher has to be smart to select which one approaches or methods which can enhance learning foreign language and character building in the teaching foreign language process.The storyline approach was specifically designed for the use at primary schools. The storyline method (Storyline for teaching children at primary schools was mainly developed in 1967 by a team of teachers from Jordanhill College of Education (now known as University of Strathclyde in Glasgow, Scotland. The primary schools in Scotland use a curriculum that involves integration of new topics, such as environmental studies and expressive arts, in their teaching foreign language process. This method could be one of alternative method that be applied in teaching foreign language to Elementary School or English Courses for Children in Indonesia.

    Full Text Available A common policy approach to reducing childhood obesity aims to shape the environment in which children spend most of their time: neighborhoods and schools. This paper uses richly detailed data on the body mass index (BMI of all New York City public school students in grades K-8 to assess the potential for place-based approaches to reduce child obesity. We document variation in the prevalence of obesity across NYC public schools and census tracts, and then estimate the extent to which this variation can be explained by differences in individual-level predictors (such as race and household income. Both unadjusted and adjusted variability across neighborhoods and schools suggest place-based policies have the potential to meaningfully reduce child obesity, but under most realistic scenarios the improvement would be modest.

    The health education learning can be promoted through children's games. How basic nutrition knowledge was provided to Indian children aged 7-10 years through nutrition games was described. The project involved teaching educational games to 882 students in 4 different primary schools over 8 months in Bombay: 478 from private fee-paying schools and 404 from non-fee-paying municipal schools. Games covered the 4 basic food groups and a balanced diet. The games were food relay, passing the parcel, throw ball, and food chain. An initial introduction to the importance of nutrition, the major nutrients, and their food sources was provided by a trained nutritionist to 30-35 students at a time. Nutrients of importance were identified as protein, energy, fat, vitamins A and C, and minerals such as calcium and iron. There were 2 games for the basic food groups followed by 2 games for the balanced diet; each game was played for 3 turns. Pretests and posttests were conducted. The Relay Game was played with 4 groups (1 group for each food group) of children standing 15 feet away from foods in plastic bags. At the signal, the first one in line ran to the end, grabbed a food appropriate to his or her food group, and returned to the rear of the line, which released the second runner to repeat the process until all the food was gone. The teacher checked the items collected and corrected mistakes. In Pass the Parcel, children sat in a circle and passed a bag filled with scrape of paper with the names of food items written on them, while music played. When the music was stopped, whoever was holding the bag drew out a food name and had to identify the food item, the basic food group, and the major nutrient in the food and its importance. In Throw Ball, 30-35 children stood in a circle with a person in the center with a ball. At each throw of the ball, the student named a food, and the following 5 students named foods that would complete a balanced diet. Then these 5 children moved out

    The current approach to the management of trichomoniasis and candidosis in sexually transmitted disease (STD) clinics in England and Wales is described. Microscopy alone was used in the diagnosis of trichomoniasis in 44% of clinics and of candidosis in 35% of clinics. Oral metronidazole was used for the treatment of trichomoniasis in women in 92% of clinics. Vaginal pessaries containing nystatin or clotrimazole were routinely used to treat candidosis in 95% of clinics. Male sexual contacts of female patients with candidosis and trichomoniasis were invited to attend for examination in 88% of clinics. Physicians in 81% of clinics prescribed treatment on epidemiological grounds for male contacts of female patients with trichomoniasis. A more uniform approach to the diagnostic categories used for the quarterly returns for cases treated epidemiologically is recommended.

    2018-05-10

    The complexity displayed by nanofluidic-based systems involves electronic and dynamic aspects occurring across different size and time scales. To properly model such kind of system, we introduced a top-down multilevel approach, combining molecular dynamics simulations (MD) with first-principles electronic transport calculations. The potential of this technique was demonstrated by investigating how the water and ionic flow through a (6,6) carbon nanotube (CNT) influences its electronic transport properties. We showed that the confinement on the CNT favors the partially hydrated Na, Cl, and Li ions to exchange charge with the nanotube. This leads to a change in the electronic transmittance, allowing for the distinguishing of cations from anions. Such an ionic trace may handle an indirect measurement of the ionic current that is recorded as a sensing output. With this case study, we are able to show the potential of this top-down multilevel approach, to be applied on the design of novel nanofluidic devices.

    2013-01-01

    The recent developments of experimental techniques have opened new opportunities and challenges for the modelling and simulation of clay materials, on various scales. In this communication, several aspects of the interaction between experimental and modelling approaches will be presented and dis-cussed. What levels of modelling are available depending on the target property and what experimental input is required? How can experimental information be used to validate models? What knowledge can modelling on different scale bring to the knowledge on the physical properties of clays? Finally, what can we do when experimental information is not available? Models implement the current nano/microscopic knowledge using experimental input, taking advantage of multi-scale approaches, and providing data or insights complementary to experiments. Future work will greatly benefit from the recent experimental developments, in particular for 3D-imaging on intermediate scales, and should also address other properties, e.g. mechanical or thermal properties.

    2011-03-01

    Full Text Available This paper reports a research programme aimed at giving a better understanding of the phenomena involved in the chloride penetration in cement-based materials. The general approach used was to solve the Nernst-Planck equation numerically for two physical ideal states that define the possible conditions under which chlorides will move through concrete. These conditions are named in this paper as voltage control and current control. For each condition, experiments and simulations were carried out in order to establish the importance of electrical variables such as voltage and current in modelling chloride transport in concrete. The results of experiments and simulations showed that if those electrical variables are included as key parameters in the modelling of chloride penetration through concrete, a better understanding of this complex phenomenon can be obtained.

    Full Text Available http://dx.doi.org/10.5007/2175-7941.2012v29n3p1121 In this paper we propose and describe the performance of an experimental activity to address the concept of friction in High School Physics practical classes. We use a low-cost and simple construction device that enables the determination of the coefficient of static friction between two materials through three different procedures. The results were coherent, with small percentage deviation, which gives reliability to the activity and can stimulate discussions in class. The activity also allows greater contextualization of concepts that are usually discussed only theoretically, requiring a higher abstraction level of the students. This can stimulate discussions and greater interaction between teacher and students.

    1988-02-01

    The moment approach is utilized to derive the full complement of neoclassical transport processes in auxiliary heated tokamaks. The effects of auxiliary heating [neutral beam injection (NBI) and ion cyclotron resonance heating (ICRH)] considered arise from the collisional interaction between the background plasma species and the fast-ion-tail species. From a known fast ion distribution function we evaluate the parallel (to the magnetic field) momentum and heat flow inputs to the background plasma. Then, through the momentum and heat flow balance equations, we can determine the induced parallel flows (and current) and radial transpot fluxes in ''equilibrium'' (on the time scale much longer than the collisional relaxation time, i.e., t >> 1ν/sub ii/). In addition to the fast-ion-induced current, the total neoclassical current includes the boostap current, which is driven by the pressure and temperature gradients, the Pfirsch-Schlueter current which is required for charge neutrality, and the neoclassical (including trapped particle effects) Spitzer current due to the parallel electric field. The radial transport fluxes also include off-diagonal compnents in the transport matrix which correspond to the Ware (neoclassical) pinch due to the inductive applied electric field an the fast-ion-induced radial fluxes, in addition to the usual pressure- and temperature-gradient-driven fluxes (particle diffusion and heat conduction). Once the tranport coefficient are completely determined, the radial fluxes and the heat fluxes can be substituted into the density and energy evolution equations to provide a complete description of ''equilibrium'' (δδt << ν/sub ii/) neoclassical transport processes in a plasma. 47 refs., 14 figs

    Full Text Available Wai Tong Chien, Sau Fong Leung, Frederick KK Yeung, Wai Kit Wong School of Nursing, Faculty of Health and Social Sciences, The Hong Kong Polytechnic University, Hung Hom, Kowloon, Hong Kong Abstract: Schizophrenia is a disabling psychiatric illness associated with disruptions in cognition, emotion, and psychosocial and occupational functioning. Increasing evidence shows that psychosocial interventions for people with schizophrenia, as an adjunct to medications or usual psychiatric care, can reduce psychotic symptoms and relapse and improve patients' long-term outcomes such as recovery, remission, and illness progression. This critical review of the literature was conducted to identify the common approaches to psychosocial interventions for people with schizophrenia. Treatment planning and outcomes were also explored and discussed to better understand the effects of these interventions in terms of person-focused perspectives such as their perceived quality of life and satisfaction and their acceptability and adherence to treatments or services received. We searched major healthcare databases such as EMBASE, MEDLINE, and PsycLIT and identified relevant literature in English from these databases. Their reference lists were screened, and studies were selected if they met the criteria of using a randomized controlled trial or systematic review design, giving a clear description of the interventions used, and having a study sample of people primarily diagnosed with schizophrenia. Five main approaches to psychosocial intervention had been used for the treatment of schizophrenia: cognitive therapy (cognitive behavioral and cognitive remediation therapy, psychoeducation, family intervention, social skills training, and assertive community treatment. Most of these five approaches applied to people with schizophrenia have demonstrated satisfactory levels of short- to medium-term clinical efficacy in terms of symptom control or reduction, level of

Specifically, in this study, two different frequency mixing algorithms, a time-domain optimization method and a discrete cosine transform(DCT) optimization method, are investigated using the experimental signals captured from the ASME standard tube. The DCT domain optimization method is computationally fast but produces larger amount of residue.

    2014-12-06

    Chronic disease among school-aged children is a public health concern, particularly for asthma and food allergy. In Chicago Public Schools (CPS), rates of asthma and food allergy among students are underreported. The aim of this study was to determine the barriers to chronic disease reporting as experienced by CPS parents and school nurses. A mixed-methods approach included focus groups and key informant interviews with parents and school nurses, and a cross-sectional survey was completed by parents. Qualitative data analysis was performed and survey data were analyzed to determine the significant demographic and knowledge variables associated with successfully completing the reporting process. The three main barriers identified were 1) a lack of parental process knowledge; 2) limited communication from schools; and 3) insufficient availability of school nurses. Parents were significantly more likely to successfully complete the reporting process if they knew about special accommodations for chronic diseases, understood the need for physician verification, and/or knew the school nurse. These findings suggest that increasing parental knowledge of the reporting process will allow schools to better identify and manage their students' chronic conditions. A parent-focused intervention informed by these results has been completed.

    Poursalehi, N.; Zolfaghari, A.; Minuchehr, A.

    2013-01-01

    Highlights: ► A new adaptive h-refinement approach has been developed for a class of nodal method. ► The resulting system of nodal equations is more amenable to efficient numerical solution. ► The benefit of the approach is reducing computational efforts relative to the uniform fine mesh modeling. ► Spatially adaptive approach greatly enhances the accuracy of the solution. - Abstract: The aim of this work is to develop a spatially adaptive coarse mesh strategy that progressively refines the nodes in appropriate regions of domain to solve the neutron balance equation by zeroth order nodal expansion method. A flux gradient based a posteriori estimation scheme has been utilized for checking the approximate solutions for various nodes. The relative surface net leakage of nodes has been considered as an assessment criterion. In this approach, the core module is called in by adaptive mesh generator to determine gradients of node surfaces flux to explore the possibility of node refinements in appropriate regions and directions of the problem. The benefit of the approach is reducing computational efforts relative to the uniform fine mesh modeling. For this purpose, a computer program ANRNE-2D, Adaptive Node Refinement Nodal Expansion, has been developed to solve neutron diffusion equation using average current nodal expansion method for 2D rectangular geometries. Implementing the adaptive algorithm confirms its superiority in enhancing the accuracy of the solution without using fine nodes throughout the domain and increasing the number of unknown solution. Some well-known benchmarks have been investigated and improvements are reported

  3. A Unified Current Loop Tuning Approach for Grid-Connected Photovoltaic Inverters

    2016-09-01

    Full Text Available High level penetration of renewable energy sources has reshaped modern electrical grids. For the future grid, distributed renewable power generation plants can be integrated in a larger scale. Control of grid-connected converters is required to achieve fast power reference tracking and further to present grid-supporting and fault ride-through performance. Among all of the aspects for converter control, the inner current loop for grid-connected converters characterizes the system performance considerably. This paper proposes a unified current loop tuning approach for grid-connected converters that is generally applicable in different cases. A direct discrete-time domain tuning procedure is used, and particularly, the selection of the phase margin and crossover frequency is analyzed, which acts as the main difference compared with the existing studies. As a general method, the approximation in the modeling of the controller and grid filter is avoided. The effectiveness of the tuning approach is validated in both simulation and experimental results with respect to power reference tracking, frequency and voltage supporting.

    With the reported startling statistics of high incidence of tooth decay and tooth loss, the current interest is focused on the development of alternate dental tissue replacement therapies. This has led to the application of dental tissue engineering as a clinically relevant method for the regeneration of dental tissues and generation of bioengineered whole tooth. Although, tissue engineering approach requires the three main key elements of stem cells, scaffold and morphogens, a conductive environment (fourth element) is equally important for successful engineering of any tissue and/or organ. The applications of this science has evolved continuously in dentistry, beginning from the application of Ca(OH)(2) in vital pulp therapy to the development of a fully functional bioengineered tooth (mice). Thus, with advances in basic research, recent reports and studies have shown successful application of tissue engineering in the field of dentistry. However, certain practical obstacles are yet to be overcome before dental tissue regeneration can be applied as evidence-based approach in clinics. The article highlights on the past achievements, current developments and future prospects of tissue engineering and regenerative therapy in the field of endodontics and bioengineered teeth (bioteeth). © 2012 The Authors.

    Ritou, M.; Garnier, S.; Furet, B.; Hascoet, J. Y.

    2014-02-01

    The paper presents a new complete approach for Tool Condition Monitoring (TCM) in milling. The aim is the early detection of small damages so that catastrophic tool failures are prevented. A versatile in-process monitoring system is introduced for reliability concerns. The tool condition is determined by estimates of the radial eccentricity of the teeth. An adequate criterion is proposed combining mechanical model of milling and angular approach.Then, a new solution is proposed for the estimate of cutting force using eddy current sensors implemented close to spindle nose. Signals are analysed in the angular domain, notably by synchronous averaging technique. Phase shifts induced by changes of machining direction are compensated. Results are compared with cutting forces measured with a dynamometer table.The proposed method is implemented in an industrial case of pocket machining operation. One of the cutting edges has been slightly damaged during the machining, as shown by a direct measurement of the tool. A control chart is established with the estimates of cutter eccentricity obtained during the machining from the eddy current sensors signals. Efficiency and reliability of the method is demonstrated by a successful detection of the damage.

    Electromagnetic and hadron showers generated by electrons of dark current (DC) can represent a significant radiation threat to the ILC linac equipment and personnel. In this study, a commissioning scenario is analysed which is considered as the worst-case scenario for the main linac regarding the DC contribution to the radiation environment in the tunnel. A normal operation scenario is analysed as well. An emphasis is made on radiation load to sensitive electronic equipment—cryogenic thermometers inside the cryomodules. Prompt and residual dose rates in the ILC main linac tunnels were also calculated in these new high-statistics runs. A novel approach was developed—as a part of general purpose Monte Carlo code MARS15—to model generation, acceleration and transport of DC electrons in electromagnetic fields inside SRF cavities. Comparisons were made with a standard approach when a set of pre-calculated DC electron trajectories is used, with a proper normalization, as a source for Monte Carlo modelling. Results of MARS15 Monte Carlo calculations, performed for the current main linac tunnel design, reveal that the peak absorbed dose in the cryogenic thermometers in the main tunnel for 20 years of operation is about 0.8 MGy. The calculated contact residual dose on cryomodules and tunnel walls in the main tunnel for typical irradiation and cooling conditions is 0.1 and 0.01 mSv/hr, respectively.

    To identify trends in medical school otolaryngology curriculum requirements. Survey of United States allopathic medical schools. A survey was sent to deans of curriculum at allopathic medical schools. We identified opportunities for medical students to learn basic concepts in otolaryngology during their undergraduate medical training. The opportunities were classified into preclinical and clinical as well as elective and mandatory rotations. Of the schools surveyed, 60% responded. Mean class size was 149 students. Sixty-eight percent of surveyed schools noted that 75% to 100% of their students participated in preclinical otolaryngology experiences, with 59% reporting a mandatory preclinical otolaryngology module for all students. Eighty-nine percent of schools offered otolaryngology as a clinical elective rotation, with a mean of 12 students participating yearly. Only 7% of schools required a mandatory otolaryngology clinical rotation. Our data suggest that medical students do not receive sufficient exposure to otolaryngology during medical school. Increased requirements for otolaryngology curriculum may be beneficial to all medical students, regardless of their specialty choice. NA.

  10. Health approaches in a widely adopted Brazilian high school biology textbook

    Directory of Open Access Journals (Sweden)

    2012-05-01

    Full Text Available Considering the long tradition of discussing health in the Brazilian school curriculum, it is important to investigate how this topic is addressed by the textbooks, the main resource used by most schools in the country. In particular, it is relevant to verify if this content is presented in a manner that contributes to the development of the students as active and critical members of the society. We analyze how health is treated in the textbook Biology, by Laurence (2005, which has been the high school Biology textbook most chosen by public school teachers among those certified by the National Program for High School Textbooks (PNLEM/2007, sponsored by the Brazilian Ministry of Education (MEC. We used categorical content analysis techniques, involving the decomposition of the texts into units of analysis, the categories, which were built in this work through analogical regroupings, by using semantic criteria. In order to investigate the treatment given to health, we applied an analytical table to the units of recording, which consist of sentences, paragraphs, and sections of the textbook that discuss contents related to health and disease. This table systematizes eight health indicators, seeking to identify three health approaches: biomedical, behavioral, and socioecological. We found 267 units of recording in the textbook and, based on their analysis, it was possible to categorize the textbook as one in which the biomedical approach prevails. Our findings are consistent with other works that indicate the prevalence of this approach in Brazilian education, and Brazilian and international textbooks. Another important finding of the work is that the behavioral approach does not hold, at least for the analyzed textbook, as a view of health different from the biomedical and socioecological approaches. After all, when the book mentions behaviors and habits of life associated with health, it generally emphasizes biological dimensions, aligning with a

    2002-01-01

    Flow regime identification for an adiabatic vertical co-current downward air-water two-phase flow in the 25.4 mm ID and the 50.8 mm ID round tubes was performed by employing an impedance void meter coupled with the neural network classification approach. This approach minimizes the subjective judgment in determining the flow regimes. The signals obtained by an impedance void meter were applied to train the self-organizing neural network to categorize these impedance signals into a certain number of groups. The characteristic parameters set into the neural network classification included the mean, standard deviation and skewness of impedance signals in the present experiment. The classification categories adopted in the present investigation were four widely accepted flow regimes, viz. bubbly, slug, churn-turbulent, and annular flows. These four flow regimes were recognized based upon the conventional flow visualization approach by a high-speed motion analyzer. The resulting flow regime maps classified by the neural network were compared with the results obtained through the flow visualization method, and consequently the efficiency of the neural network classification for flow regime identification was demonstrated.

    Geomagnetically induced currents (GICs) in power systems, which can lead to transformer damage over the short and the long term, are a result of space weather events and geomagnetic variations. For a long time, only high-latitude areas were considered to be at risk from these currents, but recent studies show that considerable GICs also appear in midlatitude and equatorial countries. In this paper, we present initial results from a GIC model using a thin-sheet approach with detailed surface and subsurface conductivity models to compute the induced geoelectric field. The results are compared to measurements of direct currents in a transformer neutral and show very good agreement for short-period variations such as geomagnetic storms. Long-period signals such as quiet-day diurnal variations are not represented accurately, and we examine the cause of this misfit. The modelling of GICs from regionally varying geoelectric fields is discussed and shown to be an important factor contributing to overall model accuracy. We demonstrate that the Austrian power grid is susceptible to large GICs in the range of tens of amperes, particularly from strong geomagnetic variations in the east-west direction.

    Gargus, Gerald Vincent

    This investigation represents an in-depth understanding of teacher professional development at the Alexander Science Center School, a dependent charter museum school established through a partnership between the California Science Center and Los Angeles Unified School District. Three methods of data collection were used. A survey was distributed and collected from the school's teachers, resulting in a prioritized list of teacher professional development needs, as well as a summary of teachers' opinions about the school's existing professional development program. In addition, six key stakeholders in the school's professional development program were interviewed for the study. Finally, documents related to the school's professional development program were analyzed. Data collected from the interviews and documents were used to develop an understand various components of the Alexander Science Center School's professional development program. Teachers identified seven areas that had a high-priority for future professional development including developing skills far working with below-grade-level students, improving the analytical skills of student in mathematics, working with English Language Learners, improving students' overall reading ability levels, developing teachers' content-area knowledge for science, integrating science across the curriculum, and incorporating hands-on activity-based learning strategies to teach science. Professional development needs identified by Alexander Science Center School teachers were categorized based on their focus on content knowledge, pedagogical content knowledge, or curricular knowledge. Analysis of data collected through interviews and documents revealed that the Alexander Science Center School's professional development program consisted of six venues for providing professional development for teachers including weekly "banked time" sessions taking place within the standard school day, grade-level meetings, teacher support

    The goal of this research was to study the weight of student variables related to homework (intrinsic homework motivation, perceived homework instrumentality, homework attitude, time spent on homework, and homework time management) and context (teacher feedback on homework and parental homework support) in the prediction of approaches to homework. 535 students of the last three courses of primary education participated in the study. Data were analyzed with hierarchical regression models and path analysis. The results obtained suggest that students’ homework engagement (high or low) is related to students´ level of intrinsic motivation and positive attitude towards homework. Furthermore, it was also observed that students who manage their homework time well (and not necessarily those who spend more time) are more likely to show the deepest approach to homework. Parental support and teacher feedback on homework affect student homework engagement through their effect on the levels of intrinsic homework motivation (directly), and on homework attitude, homework time management, and perceived homework instrumentality (indirectly). Data also indicated a strong and significant relationship between parental and teacher involvement.

  17. Health-promoting schools: evidence for a holistic approach to promoting health and improving health literacy.

    Science.gov (United States)

    Lee, Albert

    2009-01-01

    Chronic diseases are now the major causes of death and disability worldwide, and non-communicable diseases (NCD) account for the majority of the global health burden. About half of premature deaths are related to health-risking behaviours that are often established during youth and extend to adulthood. While these diseases might not be curable, they are preventable. Prevention is possible when sustained actions are directed at individuals and families, as well as at the broader social, economic and cultural determinants of NCD. A 'life-course' approach to promoting healthy behaviour should begin early in life. The aim of this article is to discuss the impact of the 'health-promoting school' (HPS) on improvements in youth health. HPS can be described as a holistic, whole-school approach in which a broad health education curriculum is supported by the environment and ethos of the school. HPS moves beyond individual behavioural change to consider organizational and policy change such as improving the physical and social environment of the school, as well as its curricula and teaching and learning methods. A positive culture for health would facilitate higher levels of health literacy by helping individuals tackle the determinants of health better as they build the personal, cognitive and social skills for maintaining good health. There is reasonable evidence to demonstrate that the whole-school approach using the HPS framework is effective in improving health, ranging from physical activities and healthy eating to emotional health. Schools adopting the HPS framework have demonstrated changes in culture and organizational practice to become more conducive to health improvement. These schools were reported to have better school health policies, higher degrees of community participation, and a more hygienic environment than non-HPS schools, and students in these schools had a more positive health behaviour profile. Health promotion and disease prevention is essential to

    Full Text Available Students with Autism Spectrum Disorder (ASD face unique challenges transitioning from high school to college and receive insufficient support to help them navigate this transition. Through a participatory collaboration with incoming and current autistic college students, we developed, implemented, and evaluated two intensive week-long summer programs to help autistic students transition into and succeed in college. This process included: (1 developing an initial summer transition program curriculum guided by recommendations from autistic college students in our ongoing mentorship program, (2 conducting an initial feasibility assessment of the curriculum [Summer Transition Program 1 (STP1], (3 revising our initial curriculum, guided by feedback from autistic students, to develop a curriculum manual, and (4 pilot-testing the manualized curriculum through a quasi-experimental pre-test/post-test assessment of a second summer program [Summer Transition Program 2 (STP2]. In STP2, two autistic college students assumed a leadership role and acted as “mentors” and ten incoming and current autistic college students participated in the program as “mentees.” Results from the STP2 pilot-test suggested benefits of participatory transition programming for fostering self-advocacy and social skills among mentees. Autistic and non-autistic mentors (but not mentees described practicing advanced forms of self-advocacy, specifically leadership, through their mentorship roles. Autistic and non-autistic mentors also described shared (e.g., empathy and unique (an intuitive understanding of autism vs. an intuitive understanding of social interaction skills that they contributed to the program. This research provides preliminary support for the feasibility and utility of a participatory approach in which autistic college students are integral to the development and implementation of programming to help less experienced autistic students develop the self

  19. Planned approaches to business and school partnerships. Does it make a difference? The business perspective.

    Lee, Kerry; Hope, John; Abdulghani, Fatima

    2016-04-01

    In many countries, schools are encouraged to link with business to add authenticity to learning. The number of these business-school partnerships has shown a marked increase over the last twenty years. Traditionally researchers investigating these partnerships have focussed on the schools' perspectives (Du, Bhattacharya, & Sen, 2010, pp. 32-33), however this New Zealand research has focused solely on the business perspective of established school partnerships. The study used a mixed methods approach utilising both online survey and semi-structured interviews. Ten out of the forty participating businesses surveyed used a brokering organisation as a way of developing and maintaining these partnerships and some developed rationales to support the partnership. This study investigated the value of using brokering organisations, rationales and designated staff to support business-school partnerships. Findings indicate that brokers and designated staff play a very effective role in enhancing business-school links, and more benefits are perceived when a rationale has been established. It is anticipated that these findings will support the development and success of business-school partnerships. Copyright © 2015 Elsevier Ltd. All rights reserved.

  20. Eddy current crack detection capability assessment approach using crack specimens with differing electrical conductivity

    Koshti, Ajay M.

    2018-03-01

    Like other NDE methods, eddy current surface crack detectability is determined using probability of detection (POD) demonstration. The POD demonstration involves eddy current testing of surface crack specimens with known crack sizes. Reliably detectable flaw size, denoted by, a90/95 is determined by statistical analysis of POD test data. The surface crack specimens shall be made from a similar material with electrical conductivity close to the part conductivity. A calibration standard with electro-discharged machined (EDM) notches is typically used in eddy current testing for surface crack detection. The calibration standard conductivity shall be within +/- 15% of the part conductivity. This condition is also applicable to the POD demonstration crack set. Here, a case is considered, where conductivity of the crack specimens available for POD testing differs by more than 15% from that of the part to be inspected. Therefore, a direct POD demonstration of reliably detectable flaw size is not applicable. Additional testing is necessary to use the demonstrated POD test data. An approach to estimate the reliably detectable flaw size in eddy current testing for part made from material A using POD crack specimens made from material B with different conductivity is provided. The approach uses additional test data obtained on EDM notch specimens made from materials A and B. EDM notch test data from the two materials is used to create a transfer function between the demonstrated a90/95 size on crack specimens made of material B and the estimated a90/95 size for part made of material A. Two methods are given. For method A, a90/95 crack size for material B is given and POD data is available. Objective of method A is to determine a90/95 crack size for material A using the same relative decision threshold that was used for material B.

  2. The Necessity to Negotiate the Syllabus in Second Chance Schools: An Innovative Approach

    Directory of Open Access Journals (Sweden)

    2010-02-01

    Full Text Available European unification and the scale of current economic and social change has led to the construction of a multidimensional, constantly evolving environment diversifying in languages and cultures, social communities and political constitutions. The demands for the maintenance and development of such a multifarious population are thus increased. Second Chance Schools (SCSs were established in Greece in 1999 as a special programme which offers education and training to adults “at risk of social exclusion” aiming at their social and economic integration. Diversity in SCSs demands a new approach to education and training, and the existence of multiple identities, values and cultures within SCSs challenges both trainers and trainees to cultivate mutual understanding and to promote democratic standards in order to ensure equality in education and facilitate SCS trainees’ inclusion in social, economic and cultural dimensions. This paper argues that EFL literacy in SCSs can best be developed on the basis of a negotiated syllabus which has been promoted by recent trends in educational theory as the most democratic and flexible syllabus that can offer significant opportunities for developing basic skills and qualifications and trigger processes of self-discovery, shared decision-making and responsibility. The paper draws its materials from a systematic research conducted in different SCSs in northern Greece over a period of 8 months. Adopting a mixed-method approach, I analysed data from a variety of different sources, such as official documentation, detailed questionnaires, semi-structured interviews with trainers of EFL literacy, and real time classroom observation. This paper outlines in detail the main elements of the negotiated syllabus and, on the basis of research findings, discuss why such a syllabus is appropriate to the teaching of EFL literacies. It also presents practical devices for the implementation of a negotiated syllabus, which

    2017-01-01

    Full Text Available A better understanding of the neural substrates that underlie motor recovery after stroke has led to the development of innovative rehabilitation strategies and tools that incorporate key elements of motor skill relearning, that is, intensive motor training involving goal-oriented repeated movements. Robotic devices for the upper limb are increasingly used in rehabilitation. Studies have demonstrated the effectiveness of these devices in reducing motor impairments, but less so for the improvement of upper limb function. Other studies have begun to investigate the benefits of combined approaches that target muscle function (functional electrical stimulation and botulinum toxin injections, modulate neural activity (noninvasive brain stimulation, and enhance motivation (virtual reality in an attempt to potentialize the benefits of robot-mediated training. The aim of this paper is to overview the current status of such combined treatments and to analyze the rationale behind them.

    2017-04-01

    Giant cell arteritis and Takayasu arteritis are the two major forms of idiopathic large vessel vasculitis. High doses of glucocorticoids are effective in inducing remission in both conditions, but relapses and recurrences are common, requiring prolonged glucocorticoid treatment with the risk of the related adverse events. Areas covered: In this article, we will review the standard and biological treatment strategies in large vessel vasculitis, and we will focus on the current approaches to these diseases. Expert commentary: The results of treatment trials with conventional immunosuppressive agents such as methotrexate, azathioprine, mycophenolate mofetil, and cyclophosphamide have overall been disappointing. TNF-α blockers are ineffective in giant cell arteritis, while observational evidence and a phase 2 randomized trial support the use of tocilizumab in relapsing giant cell arteritis. Observational evidence strongly supports the use of anti-TNF-α agents and tocilizumab in Takayasu patients with relapsing disease. However biological agents are not curative, and relapses remain common.

    Fox, JL, Scanlan, AT, and Stanton, R. A review of player monitoring approaches in basketball: current trends and future directions. J Strength Cond Res 31(7): 2021-2029, 2017-Effective monitoring of players in team sports such as basketball requires an understanding of the external demands and internal responses, as they relate to training phases and competition. Monitoring of external demands and internal responses allows coaching staff to determine the dose-response associated with the imposed training load (TL), and subsequently, if players are adequately prepared for competition. This review discusses measures reported in the literature for monitoring the external demands and internal responses of basketball players during training and competition. The external demands of training and competition were primarily monitored using time-motion analysis, with limited use of microtechnology being reported. Internal responses during training were typically measured using hematological markers, heart rate, various TL models, and perceptual responses such as rating of perceived exertion (RPE). Heart rate was the most commonly reported indicator of internal responses during competition with limited reporting of hematological markers or RPE. These findings show a large discrepancy between the reporting of external and internal measures and training and competition demands. Microsensors, however, may be a practical and convenient method of player monitoring in basketball to overcome the limitations associated with current approaches while allowing for external demands and internal responses to be recorded simultaneously. The triaxial accelerometers of microsensors seem well suited for basketball and warrant validation to definitively determine their place in the monitoring of basketball players. Coaching staff should make use of this technology by tracking individual player responses across the annual plan and using real-time monitoring to minimize factors such as fatigue

    2015-11-01

    The design of 3D constructs with adequate properties to instruct and guide cells both in vitro and in vivo is one of the major focuses of tissue engineering. Successful tissue regeneration depends on the favorable crosstalk between the supporting structure, the cells and the host tissue so that a balanced matrix production and degradation are achieved. Herein, the major occurring events and players in normal and regenerative tissue are overviewed. These have been inspiring the selection or synthesis of instructive cues to include into the 3D constructs. We further highlight the importance of a multiscale perception of the range of features that can be included on the biomimetic structures. Lastly, we focus on the current and developing tissue-engineering approaches for the preparation of such 3D constructs: top-down, bottom-up and integrative. Bottom-up and integrative approaches present a higher potential for the design of tissue engineering devices with multiscale features and higher biochemical control than top-down strategies, and are the main focus of this review.

    2011-01-01

    Full Text Available The importance attributed to the territorial dimension of the European Union cohesion policy steadily influences its successive reforms and adaptations, while in recent years there has been an evolution in the way this particular dimension of cohesion policy is perceived. Important evidence for this is the way in which the Community Strategic Guidelines on cohesion 2007-13 take account of the territorial dimension of cohesion policy. This paper discusses the territorial approach to cohesion policy in relation to both policy and practice. Specifically, it examines the territorial dimension of regional development planning in Greece as it has emerged in the relevant official documents, namely the successive three Community Support Frameworks since 1989 and the National Strategic Reference Framework for the current 2007-13 period. The territorial dimension of the organization of the planning system is also considered in an effort to understand limitations and prospects, in light of the importance of the territorial approach to cohesion policy post-2013.

    2016-01-01

    Full Text Available Recent advances in biomaterial science and tissue engineering technology have greatly spurred the development of regenerative endodontics. This has led to a paradigm shift in endodontic treatment from simply filling the root canal systems with biologically inert materials to restoring the infected dental pulp with functional replacement tissues. Currently, cell transplantation has gained increasing attention as a scientifically valid method for dentin-pulp complex regeneration. This multidisciplinary approach which involves the interplay of three key elements of tissue engineering—stem cells, scaffolds, and signaling molecules—has produced an impressive number of favorable outcomes in preclinical animal studies. Nevertheless, many practical hurdles need to be overcome prior to its application in clinical settings. Apart from the potential health risks of immunological rejection and pathogenic transmission, the lack of a well-established banking system for the isolation and storage of dental-derived stem cells is the most pressing issue that awaits resolution and the properties of supportive scaffold materials vary across different studies and remain inconsistent. This review critically examines the classic triad of tissue engineering utilized in current regenerative endodontics and summarizes the possible techniques developed for dentin/pulp regeneration.

    The aim was to examine main reasons for students' medical school choice and their relationship with students' characteristics and motivation during the students' medical study. In this multisite cross-sectional study, all Year-1 and Year-4 students who had participated in a selection procedure in one of the three Dutch medical schools included in the study were invited to complete an online survey comprising personal data, their main reason for medical school choice and standard, validated questionnaires to measure their strength of motivation (Strength of Motivation for Medical School-Revised) and autonomous and controlled type of motivation (Academic Self-regulation Questionnaire). Four hundred seventy-eight students participated. We performed frequency analyses on the reasons for medical school choice and regression analyses and ANCOVAs to study their associations with students' characteristics and motivation during their medical study. Students indicated 'city' (Year-1: 24.7%, n=75 and Year-4: 36.0%, n=52) and 'selection procedure' (Year-1: 56.9%, n=173 and Year-4: 46.9%, n=68) as the main reasons for their medical school choice. The main reasons were associated with gender, age, being a first-generation university student, ethnic background and medical school, and no significant associations were found between the main reasons and the strength and type of motivation during the students' medical study. Most students had based their medical school choice on the selection procedure. If medical schools desire to achieve a good student-curriculum fit and attract a diverse student population aligning the selection procedure with the curriculum and taking into account various students' different approaches is important.

    The design of the repository for final disposal of spent nuclear fuel proposed by SKB is based on a multi-barrier system, in which the geosphere and biosphere are the utmost barrier surrounding the engineer barriers. This report briefly reviews the current approach taken by SKB to account for hydrological and ecological processes at the geosphere-biosphere interface (GBI) and their future plans in this area. A simple analysis was performed to shift the focus of performance assessment involving geosphere-biosphere interface modelling from the very simplistic assumption that the quaternary sediments are bypassed to one in which a more detailed model for sub-surface flows is included. This study indicated that, for many assumed ecosystem descriptions, the presence of the GBI leads to lower maximum doses to individual humans compared to a case when the GBI is neglected. This effect is due to the additional 'barrier' offered by the GBI. The main exposure pathways were assumed to occur through the food web. However, particularly the leakage on land through the stream-network and lakes can lead to higher doses due to ecosystem interaction with arable land. A scenario that gives particularly long duration of doses occurs due to land rise and with the transformation of the former bay and lake bed sediments into agricultural land. This effect is due to the significant retention or accumulation in aquatic sediment, which causes high activities to build up with time. Particularly, in combination with changing conditions in climate, humans life-style or geographic conditions (land rise, deforestation,etc.) doses to individual humans can be large.

    Control programmes generally use a school-based strategy of mass drug administration to reduce morbidity of schistosomiasis and soil-transmitted helminthiasis (STH) in school-aged populations. The success of school-based programmes depends on treatment coverage. The community-directed treatment (ComDT) approach has been implemented in the control of onchocerciasis and lymphatic filariasis in Africa and improves treatment coverage. This study compared the treatment coverage between the ComDT approach and the school-based treatment approach, where non-enrolled school-aged children were invited for treatment, in the control of schistosomiasis and STH among enrolled and non-enrolled school-aged children. Coverage during the first treatment round among enrolled children was similar for the two approaches (ComDT: 80.3% versus school: 82.1%, P=0.072). However, for the non-enrolled children the ComDT approach achieved a significantly higher coverage than the school-based approach (80.0 versus 59.2%, P<0.001). Similar treatment coverage levels were attained at the second treatment round. Again, equal levels of treatment coverage were found between the two approaches for the enrolled school-aged children, while the ComDT approach achieved a significantly higher coverage in the non-enrolled children. The results of this study showed that the ComDT approach can obtain significantly higher treatment coverage among the non-enrolled school-aged children compared to the school-based treatment approach for the control of schistosomiasis and STH.

    2012-04-01

    Despite longstanding concern, provision of undergraduate ENT teaching has not improved in response to the aims of the UK General Medical Council's initiative Tomorrow's Doctors. Previous studies have demonstrated poor representation of ENT within the undergraduate curriculum. We aimed to identify current practice in order to establish undergraduate ENT experience across UK medical schools, a timely endeavour in light of the General Medical Council's new 2011-2013 education strategy. Questionnaires were sent to ENT consultants, medical school deans and students. All schools with a clinical curriculum were anonymously represented. Our outcome measures were the provision of mandatory or optional ENT placements, and their duration and content. A compulsory ENT placement was available to over half (53 per cent) of the students. Ten of the 26 participating schools did not offer an ENT attachment. The mean mandatory placement was 8 days. Overall, 38 per cent of students reported a satisfactory compulsory ENT placement. Most ENT consultants questioned considered that newly qualified doctors were not proficient in managing common ENT problems that did not require specialist referral. Little improvement in the provision of undergraduate ENT teaching was demonstrated. An increase in the proportion of students undertaking ENT training is necessary. Time and curriculum constraints on medical schools mean that optimisation of available resources is required.

  13. High school teachers' perspectives on effective approaches for teaching biology to students with special needs

    Kos, Agnieszka

    The demands of national educational reforms require high school biology teachers to provide high quality instruction to students with and without special needs. The reforms, however, do not provide teachers with adequate teaching strategies to meet the needs of all students in the same context. The purpose of this grounded theory study was to understand high school biology teachers' perspectives, practices, and challenges in relation to teaching students with special needs. This approach was used to develop a substantive model for high school biology teachers who are challenged with teaching students with and without special needs. Data were collected via in-depth interviews with 15 high school teachers in a Midwestern school district. The data were analyzed using open coding, axial coding, and selective coding procedures in accordance with the grounded theory approach. Essential model components included skills and training for teachers, classroom management strategies, teaching strategies, and student skills. The emergent substantive theory indicated that that teacher preparation and acquired skills greatly influence the effectiveness of inclusion implementation. Key findings also indicated the importance of using of a variety of instructional strategies and classroom management strategies that address students' special needs and their learning styles. This study contributes to social change by providing a model for teaching students and effectively implementing inclusion in regular science classrooms. Following further study, this model may be used to support teacher professional development and improve teaching practices that in turn may improve science literacy supported by the national educational reforms.

    Selection of medical students at South African (SA) medical schools must promote equitable and fair access to students from all population groups, while ensuring optimal student throughput and success, and training future healthcare practitioners who will fulfil the needs of the local society. In keeping with international practices, a variety of academic and non-academic measures are used to select applicants for medical training programmes in SA medical schools. To provide an overview of the selection procedures used by all eight medical schools in SA, and the student demographics (race and gender) at these medical schools, and to determine to what extent collective practices are achieving the goals of student diversity and inclusivity. A retrospective, quantitative, descriptive study design was used. All eight medical schools in SA provided information regarding selection criteria, selection procedures, and student demographics (race and gender). Descriptive analysis of data was done by calculating frequencies and percentages of the variables measured. Medical schools in SA make use of academic and non-academic criteria in their selection processes. The latter include indices of socioeconomic disadvantage. Most undergraduate medical students in SA are black (38.7%), followed by white (33.0%), coloured (13.4%) and Indian/Asian (13.6%). The majority of students are female (62.2%). The number of black students is still proportionately lower than in the general population, while other groups are overrepresented. Selection policies for undergraduate medical programmes aimed at redress should be continued and further refined, along with the provision of support to ensure student success.

    Disagreement exists over whether permissive minimum legal drinking age (MLDA) laws affected underage adolescents (e.g., those age 17 years with the MLDA of 18). We used MLDA changes during the 1970s and 1980s as a natural experiment to investigate how underage exposure to permissive MLDA affected high school dropout. MLDA exposure was added to two data sets: (a) the 5% public use microdata samples of the 1990 and 2000 censuses (n = 3,671,075), and (b) a combined data set based on the 1991-1992 National Longitudinal Alcohol Epidemiological Survey (NLAES) and the 2001-2002 National Epidemiological Survey on Alcohol and Related Conditions (NESARC; n = 16,331). We used logistic regression to model different thresholds of MLDA on high school dropout. We also estimated models conditioned on demographic variables and familial risk of developing alcohol problems. Only the MLDA of 18 predicted high school dropout. Exposure was associated with 4% and 13% higher odds of high school dropout for the census and NLAES/NESARC samples, respectively. We noted greater impact on women (5%-18%), Blacks (5%-19%), and Hispanics (6%). Self-report of parental alcohol problems was associated with 40% higher odds, which equals a 4.14-point increase in dropout rate for that population. The MLDA of 18 likely had a large impact on high school dropout rates, suggesting that the presence of legal-aged peers in a high school setting increased access to alcohol for younger students. Our results also suggest that policy can promote less dangerous drinking behavior even when familial risk of alcohol use disorders is high.

    2001-01-01

    This study was conducted to identify factors that influenced milk-drinking behaviors of elementary school children in North Texas. Ten focus groups with a total of 41 children aged 6 to 11 years were conducted using a grounded theory approach. Based on the principles of Social Learning Theory, milk preferences and health beliefs were identified as personal factors that influenced drinking. Cafeteria rules, milk flavor, product packaging, modeling by adults, and shared experiences were environmental factors. The data suggest that school cafeterias can capitalize on their unique position to offer milk-drinking opportunities that children can share to combine nutrition education with sensory experience.

    Fostering cultural competence in higher education institutions is essential, particularly in training future health care workers to care for diverse populations. The opportunity to explore techniques to address diversity and cultural competence at a new medical school was undertaken by a multidisciplinary team of librarians, faculty, staff, and medical students. From 2011 to 2015, the team sponsored a voluntary programming series to promote cultural competence and raise awareness of health care disparities for the medical school. Thirteen events were hosted with 562 participants across all. This approach to diversity proved effective and could be adapted in any higher education setting.

    Full Text Available Background Despite of healthy nutrition recommendations have been offered in recent decades, researches show an increasing rate of unhealthy junk food consumption among primary school children. The aim of this study was to investigate the effects of health promotion intervention on the school food buffets and the changes in nutritional behaviors of the students. Materials and Methods In this Quasi-interventional study, eight schools agreed to participate in Tabriz city, Iran. The schools were randomly selected and divided into an intervention and a control group, and a pretest was given to both groups. A four weeks interventional program was conducted in eight randomly selected schools of the city based on the socio-ecological model. A check list was designed for the assessment of food items available at the schools’ buffets, a 60-item semi-quantitative food frequency questionnaire (FFQ was used to assess the rate of food consumption and energy intake. Results evaluation and practice were analyzed using the Wilcoxon, Mann Whitney-U and Chi-square tests. Results The findings revealed reduction in the intervention group between before and after intervention with regard the range of junk food consumption, except for the sweets consumption. The number of junk foods provided in the schools buffets reduced in the intervention group. After the intervention on the intervention group significant decreases were found in the intake of energy, fat and saturated fatty acids compared to the control group (p = 0.00.   Conclusion In order to design effective school food environment promotion programs, school healthcare providers should consider multifaceted approaches.

  4. A Practical Approach to Water Education in Secondary Schools in Penang, Malaysia

    Soo, P. W.; Cheam, C. S.

    2012-04-01

    In recent years, water problems have become a vital issue in our country, due to increasing population growth and urbanization. According to Prof Ngai Weng Chan, the President of Water Watch Penang (WWP), Malaysia has experienced mounting environmental degradation, and urban environmental woes in main cities like Penang. One of the many water issues affecting Malaysians is the sustainability of water that is closely related to unsustainable water supply management (Chan, 2004). Traditionally in Malaysia, Water Supply Management (WSM) and Water Demand Management (WDM) are based on the top-down-approach hierarchy. However, consumers have not been factored into the decision-making. As a result of increasing water consumption, many states in Malaysia are facing water shortages. We believe that the water consumers like our students can assist in water conservation. Education begins in school. We are certain that students with positive awareness can ultimately result in a water saving society in Malaysia. We have planned for a project that will be carried out at a local secondary school in Penang (Penang Chung Ling High School). The objective of this project is to increase the awareness among secondary students on water issues locally and globally. An initial 100 students from Chung Ling High School will be targeted for our project. We proposed to carry out water auditing of Penang Chung Ling High School to bring about awareness of water usage in the school premises for a period of time. Next, we will identify practical steps to help conserve water in Chung Ling High School. Part of the project includes formulating a water quiz to instill water awareness among the students. Hopefully with the effort to quantify the amount of water loss in unattended leaky taps will help adopting positive behavioral traits to enhance water conservation. Finally, we will look into ways to harvest rainfall for the school with the participation of these students.

    Human-wildlife conflict (HWC) is a conservation concern that increasingly threatens the continued existence of some of the world's most endangered species. With an increase in human population, urban sprawl and subsequent encroachment on wild land, human and wildlife interaction has become inevitable. In the majority of cases, this interaction results in a negative outcome for humans, wildlife or both. In China, these key elements, along with a decrease in wild prey species, have resulted in the expansion of HWC encounters, and the need for alleviating this conflict has become a conservation priority. Loss of human life, livestock and/or crops is most often the catalysts that fuel HWC. Techniques to alleviate conflict around the world have included preventative measures and mitigation techniques, such as financial compensation and other incentive programs. Both types of measures have had variable success. We review the current status of human-carnivore conflict management in China, and, drawing lessons from around the globe, we make recommendations for improving conservation management in China. For example, an increase in law enforcement in nature reserves is vital to reducing human disturbance in prime carnivore habitat, thereby reducing conflict encounters. Also, modifications to current wildlife compensation programs, so that they are linked with preventative measures, will ensure that moral hazards are avoided. Furthermore, investigating the potential for a community self-financed insurance scheme to fund compensation and increasing efforts to restore wild prey populations will improve the outcome for wildlife conservation. Ultimately, HWC management in China will greatly benefit from an integrative approach. © 2012 ISZS, Blackwell Publishing and IOZ/CAS.

Review: Current trends in coral transplantation – an approach to preserve biodiversity. Biodiversitas 14: 43-53. The increasing rates of coral mortality associated with the rise in stress factors and the lack of adequate recovery worldwide have urged recent calls for actions by the scientific, conservation, and reef management communities. This work reviews the current trends in coral transplantation. Transplantation of coral colonies or fragments, whether from aqua-, mariculture or harvesting from a healthy colony, has been the most frequently recommended action for increasing coral abundance on damaged or degraded reefs and for conserving listed or “at-risk” species. Phytoplanktons are important for providing transplanted corals with complex organic compounds through photosynthesis. Artificial surfaces like concrete blocks, wrecks or other purpose-designed structures can be introduced for larval settlement. New surfaces can also be created through electrolysis. Molecular biological tools can be used to select sites for rehabilitation by asexual recruits. Surface chemistry and possible inputs of toxic leachate from artificial substrates are considered as important factors affecting natural recruitment. Transplants should be carefully maintained , revisited and reattached at least weekly in the first month and at least fortnightly in the next three months. Studies on survivorship and the reproductive ability of transplanted coral fragments are important for coral reef restoration. A coral nursery may be considered as a pool for local species that supplies reef-managers with unlimited coral colonies for sustainable management. Transplanting corals for making artificial reefs can be useful for increasing biodiversity, providing tourist diving, fishing and surfing; creating new artisanal and commercial fishing opportunities

  8. An approach for integrating media education into everyday school-life and instruction at secondary school level

    Full Text Available The new media as a challenge for school education require to redefine its aims and methods. It is no longer sufficient to transmit knowledge and help young people to build up special competences. In addition and primarily they must learn to deal with unknown problems in the future, with uncertainty and insecurity, with an increasing lot of information, changing knowledge and truth and with the unknown. Therefore school must help students to build up flexible structures of operational thinking and orientation, abstract conceptual frames, phantasy and creativity and acquire the capability of learning to learn, to reorganize learning structures and knowledge and the ability for lifelong learning. within this context media in schools have two fundamental functions: they are instruments of teaching-learning-processes as well as subject matter helping students to acquire media competence. Our approach to integrated media education for secondary schools can be characterized as follows: It should imply all sorts of media, it should involve all teachers and embrace all subject matters (lessons. There should no longer be made a distinction between media education and computer literacy because of the integration of all media on the basis of ongoing digitalization. The different media with their specific capacities should be used naturally as a means of improving teaching and learning, as tools for problem-solving and coping with tasks, and as instruments of communication and self-reflexion, of documentation and formation, of expression and publicity. The realization of a sustainable media education is confronted with two difficulties: 1. Most teachers mostly are not trained for media education and they fear the great burden of this task. 2. Media education requires open forms and varying methods of instruction and specific media facilities must be at hand at any time and everywhere.

    2009-11-01

    The recent government decision to establish a new medical school, the fifth in Israel, is an opportune moment to reflect on the state of Basic Medical Education (BME) in the country and globally. It provides a rare opportunity for planning an educational agenda tailored to local needs. This article moves from a description of the context of Israeli health care and the medical education system to a short overview of two existing Israeli medical schools where reforms have recently taken place. This is followed by an assessment of Israeli BME and an effort to use the insights from this assessment to inform the fifth medical school blueprint. The fifth medical school presents an opportunity for further curricular reforms and educational innovations. Reforms and innovations include: fostering self-directed professional development methods; emphasis on teaching in the community; use of appropriate educational technology; an emphasis on patient safety and simulation training; promoting the humanities in medicine; and finally the accountability to the community that the graduates will serve.

    2010-08-01

    Full Text Available This study examines the Internet usage of high school students for educational needs in respect to their learning approaches. The “learning approach” categorizes individuals as ‘surface learners’ and ‘deep learners’. Surface learners mainly choose to rehearse and memorize the course material they work on and they acquire the information they need to learn in a disconnected way, by memorization. On the other hand, deep learners want to grasp the meaning of the course material. In the study, adapted Turkish version of Learning Process Questionnaire (LPQ was used to determine high school students’ learning approaches. 921 secondary school students were subjected and the Cronbach alpha values were 0.73 for a deep approach and 0.66 for a surface approach. According to the data obtained, surface learners use the Internet more when compared to deep learners, though they use it for non-instructional purposes. The ratios of the Internet use of deep learners for educational needs are higher when compared to those of surface learners. Ratios of the Internet use for educational needs by the students who are given assignments requiring the use of the Internet are higher.

  18. Approach to integrate current safeguards measures with additional protocol requirements at national level

    2001-01-01

    Peru adhered to the Additional Protocol in March 2000 which was also approved by the Congress in May 2001. After approval by law the obligations derived from this Additional Protocol will be in force after 180 days. After the signing of the Protocol an approach was designed to help better fulfill these requirements in an integrated way with the previous measures. As first stage, a review of the current state of safeguards was undertaken. Under the current agreement (an INFCIRC/153 type agreement) the reporting is less complicated and inexpensive to be carried out because these reports include only the declared nuclear material and the features of declared facilities where the nuclear material is used. No other related facility or material or activity needs to be declared. In Peru there are only two MBAs where low enriched uranium (LEU) is used and the record system includes general ledgers, inventory records and operational books. The results of national inspections and copies of reports and communications sent to the IAEA are also kept in this system. Under the agreement and subsidiary arrangements material balance reports (MBR), physical inventory listings (PIL) and inventory change reports (ICR) are prepared and submitted to the IAEA at scheduled periods. The MBR and PIL reports are sent after yearly regular inspections carried out by the IAEA. The ICR is sent just every time when an import or export of nuclear material is made. The time devoted to carry out all of these activities is not so extensive for both the State System for Accountability and Control (SSAC) and the users because of the limited nuclear activities in the country. Because of the characteristics and limited quantities of nuclear material the efforts for inspection and reporting activities are few. Another subject under review was the procedure for controlling the imports of nuclear material. Under the current agreement this subject was not a problem, as all of the radioactive and nuclear

    Vocational high school (Sekolah Menengah Kejuruan / SMK) aims to prepare mid-level skilled labors to work in the industry and are able to create self-employment opportunities. For those reasons, the curriculum in SMK should be based on meeting the needs of the industries and is able to prepare learners to master the competence in accordance with the skills program of their choice. Production based curriculum is the curriculum which the learning process is designed together with the production process or using production process as a learning medium. This approach with the primary intention to introduce students with the real working environment and not merely simulations. In the production-based curriculum implementation model, students are directly involved in the industry through the implementation of industrial working practices, do work on production units in school, and do practical work in school by doing the job as done in the industry by using industry standards machines.

  20. Examination of the Current Approaches to State-Level Nuclear Security Evaluation

    Kim, Chan; Yim, Mansung; Kim, So Young

    2014-01-01

    An effective global nuclear materials security system will cover all materials, employ international standards and best practices, and reduce risks by reducing weapons-usable nuclear material stocks and the number of locations where they are found. Such a system must also encourage states to accept peer reviews by outside experts in order to demonstrate that effective security is in place. It is thus critically important to create an integrative framework of state-level evaluation of nuclear security as a basis for measuring the level and progress of international effort to secure and control all nuclear materials. There have been studies to represent state-level nuclear security with a quantitative metric. A prime example is the Nuclear Materials Security Index (NMSI) by the Nuclear Threat Initiative (NTI). Another comprehensive study is the State Level Risk Metric by Texas A and M University (TAMU). This paper examines the current methods with respect to their strengths and weaknesses and identifies the directions for future research to improve upon the existing approaches

    2015-01-01

    Both obesity and asthma are highly prevalent, complex diseases modified by multiple factors. Genetic, developmental, lung mechanical, immunological and behavioural factors have all been suggested as playing a causal role between the two entities; however, their complex mechanistic interactions are still poorly understood and evidence of causality in children remains scant. Equally lacking is evidence of effective treatment strategies, despite the fact that imbalances at vulnerable phases in childhood can impact long-term health. This review is targeted at both clinicians frequently faced with the dilemma of how to investigate and treat the obese asthmatic child and researchers interested in the topic. Highlighting the breadth of the spectrum of factors involved, this review collates evidence regarding the investigation and treatment of asthma in obese children, particularly in comparison with current approaches in 'difficult-to-treat' childhood asthma. Finally, the authors propose hypotheses for future research from a systems-based perspective. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2016-02-01

    Pulmonary arterial hypertension (PAH) is a severe condition causing significant morbidity and mortality in patients with systemic sclerosis (SSc). Despite the use of specific treatments, SSc-PAH survival remains poorer than in idiopathic PAH (IPAH). Recent therapeutic advances in PAH show a lower magnitude of response in SSc-PAH and a higher risk of adverse events, as compared to IPAH. The multifaceted underlying mechanisms and the multisystem nature of SSc probably explain part of the worse outcomes in SSc-PAH compared to IPAH. This review describes the current management of SSc-PAH with an emphasis on the impact of the different organ involvements in the prognosis and treatment response. An earlier detection of PAH and a better characterization of the clinical phenotypes of SSc-PAH are warranted in clinical practice and future trials. Determinants of prognosis, surrogate markers of clinical improvement or worsening, and relevance of the common endpoints used in clinical trials should be evaluated in this specific population. A multidisciplinary approach in expert referral centers is mandatory for SSc-PAH management.

  3. The effects of strontium on bone mineral: A review on current knowledge and microanalytical approaches.

    Querido, William; Rossi, Andre L; Farina, Marcos

    2016-01-01

    The interest in effects of strontium (Sr) on bone has greatly increased in the last decade due to the development of the promising drug strontium ranelate. This drug is used for treating osteoporosis, a major bone disease affecting hundreds of millions of people worldwide, especially postmenopausal women. The novelty of strontium ranelate compared to other treatments for osteoporosis is its unique effect on bone: it simultaneously promotes bone formation by osteoblasts and inhibits bone resorption by osteoclasts. Besides affecting bone cells, treatment with strontium ranelate also has a direct effect on the mineralized bone matrix. Due to the chemical similarities between Sr and Ca, a topic that has long been of particular interest is the incorporation of Sr into bones replacing Ca from the mineral phase, which is composed by carbonated hydroxyapatite nanocrystals. Several groups have analyzed the mineral produced during treatment; however, most analysis were done with relatively large samples containing numerous nanocrystals, resulting thus on data that represents an average of many crystalline domains. The nanoscale analysis of the bone apatite crystals containing Sr has only been described in a few studies. In this study, we review the current knowledge on the effects of Sr on bone mineral and discuss the methodological approaches that have been used in the field. In particular, we focus on the great potential that advanced microscopy and microanalytical techniques may have on the detailed analysis of the nanostructure and composition of bone apatite nanocrystals produced during treatment with strontium ranelate.

    Diabetes is a growing global health concern, as is obesity. Diabetes and obesity are intrinsically linked: obesity increases the risk of diabetes and also contributes to disease progression and cardiovascular disease. Although the benefits of weight loss in the prevention of diabetes and as a critical component of managing the condition are well established, weight reduction remains challenging for individuals with type 2 diabetes due to a host of metabolic and psychological factors. For many patients, lifestyle intervention is not enough to achieve weight loss, and alternative options, such as pharmacotherapy, need to be considered. However, many traditional glucose-lowering medications may lead to weight gain. This article focuses on the potential of currently available pharmacological strategies and on emerging approaches in development to support the glycemic and weight-loss goals of individuals with type 2 diabetes. Two pharmacotherapy types are considered: those developed primarily for blood glucose control that have a favorable effect on body weight and those developed primarily to induce weight loss that have a favorable effect on blood glucose control. Finally, the potential of combination therapies for the management of obese patients with type 2 diabetes is discussed. © 2015 by the American Diabetes Association.

    The screening laboratory has a critical role in the post-transfusion safety. The success of its targets and efficiency depends on the management system used. Even though the European Union directive 2002/98/EC requires a quality management system in blood establishments, its requirements for screening laboratories are generic. Complementary approaches are needed to implement a quality management system focused on screening laboratories. This article briefly discusses the current good manufacturing practices and good laboratory practices, as well as the trends in quality management system standards. ISO 9001 is widely accepted in some European Union blood establishments as the quality management standard, however this is not synonymous of its successful application. The ISO "risk-based thinking" is interrelated with the quality risk-management process of the EuBIS "Standards and criteria for the inspection of blood establishments". ISO 15189 should be the next step on the quality assurance of a screening laboratory, since it is focused on medical laboratory. To standardize the quality management systems in blood establishments' screening laboratories, new national and European claims focused on technical requirements following ISO 15189 is needed.

    Non-invasive transcranial brain stimulation (NTBS) techniques such as transcranial magnetic stimulation (TMS) and transcranial current stimulation (TCS) are important tools in human systems and cognitive neuroscience because they are able to reveal the relevance of certain brain structures or neuronal activity patterns for a given brain function. It is nowadays feasible to combine NTBS, either consecutively or concurrently, with a variety of neuroimaging and electrophysiological techniques. Here we discuss what kind of information can be gained from combined approaches, which often are technically demanding. We argue that the benefit from this combination is twofold. Firstly, neuroimaging and electrophysiology can inform subsequent NTBS, providing the required information to optimize where, when, and how to stimulate the brain. Information can be achieved both before and during the NTBS experiment, requiring consecutive and concurrent applications, respectively. Secondly, neuroimaging and electrophysiology can provide the readout for neural changes induced by NTBS. Again, using either concurrent or consecutive applications, both "online" NTBS effects immediately following the stimulation and "offline" NTBS effects outlasting plasticity-inducing NTBS protocols can be assessed. Finally, both strategies can be combined to close the loop between measuring and modulating brain activity by means of closed-loop brain state-dependent NTBS. In this paper, we will provide a conceptual framework, emphasizing principal strategies and highlighting promising future directions to exploit the benefits of combining NTBS with neuroimaging or electrophysiology.

    Vascular thrombosis and pregnancy morbidity represent the clinical manifestations of antiphospholipid syndrome (APS), which is serologically characterized by the persistent positivity of antiphospholipid antibodies (aPL). Antiplatelet and anticoagulant agents currently provide the mainstay of APS treatment. However, the debate is still open: controversies involve the intensity and the duration of anticoagulation and the treatment of stroke and refractory cases. Unfortunately, the literature cannot provide definite answers to these controversial issues as it is flawed by many limitations, mainly due to the recruitment of patients not fulfilling laboratory and clinical criteria for APS. The recommended therapeutic management of different aPL-related clinical manifestations is hereby presented, with a critical appraisal of the evidence supporting such approaches. Cutting edge therapeutic strategies are also discussed, presenting the pioneer reports about the efficacy of novel pharmacological agents in APS. Thanks to a better understanding of aPL pathogenic mechanisms, new therapeutic targets will soon be explored. Much work is still to be done to unravel the most controversial issues about APS management: future studies are warranted to define the optimal management according to aPL risk profile and to assess the impact of a strict control of cardiovascular risk factors on disease control.

    Full Text Available This research aims to model Serbian current account determinants for the period Q1 2002 - Q4 2012. Taking into account the majority of relevant determinants, using the Jackknife Model Averaging approach, 48 different models have been estimated, where 1254 equations needed to be estimated and averaged for each of the models. The results of selected representative models indicate moderate persistence of the CA and positive influence of: fiscal balance, oil trade balance, terms of trade, relative income and real effective exchange rates, where we should emphasise: (i a rather strong influence of relative income, (ii the fact that the worsening of oil trade balance results in worsening of other components (probably non-oil trade balance of CA and (iii that the positive influence of terms of trade reveals functionality of the Harberger-Laursen-Metzler effect in Serbia. On the other hand, negative influence is evident in case of: relative economic growth, gross fixed capital formation, net foreign assets and trade openness. What particularly stands out is the strong effect of relative economic growth that, most likely, reveals high citizens' future income growth expectations, which has negative impact on the CA.

    Tactical match performance depends on the quality of actions of individual players or teams in space and time during match-play in order to be successful. Technological innovations have led to new possibilities to capture accurate spatio-temporal information of all players and unravel the dynamics and complexity of soccer matches. The main aim of this article is to give an overview of the current state of development of the analysis of position data in soccer. Based on the same single set of position data of a high-level 11 versus 11 match (Bayern Munich against FC Barcelona) three different promising approaches from the perspective of dynamic systems and neural networks will be presented: Tactical performance analysis revealed inter-player coordination, inter-team and inter-line coordination before critical events, as well as team-team interaction and compactness coefficients. This could lead to a multi-disciplinary discussion on match analyses in sport science and new avenues for theoretical and practical implications in soccer.

    Full Text Available This review article attempts to review current studies related to Citizenship Education (CE in order to shed light on the provisions of citizenship education in the Kingdom of Saudi Arabia (KSA. The review examines the significance of   CE in the KSA. It also explores the history of CE in the KSA followed by its national identity, as this too, affects the nature of the CE offered in the country. Then the article identifies and explores the implementation of CE in the KSA. In addition, the article discusses the approaches of introducing Citizenship Education in the KSA, its content and implementation. It can be argued that Islam has played a crucial role in shaping Saudi citizens’ private and national identities and their national values. The study also found that CE in Saudi Arabia faces multiple challenges. It emphasizes citizens’ responsibilities, duties, identity formation, and obedience towards the system and how one can achieve them. It also appears that promoting freedom, equality, fairness, freedom of expression and participation in the decision making process is poorly addressed. Moreover, lack of teaching aids and lack of specialist teachers and training are some major challenges to implement CE in the KSA. The article ends by drawing some conclusions.

    Issue addressed Our Watch led a complex 12-month evaluation of a whole school approach to Respectful Relationships Education (RRE) implemented in 19 schools. RRE is an emerging field aimed at preventing gender-based violence. This paper will illustrate how from an implementation science perspective, the evaluation was a critical element in the change process at both a school and policy level. Methods Using several conceptual approaches from systems science, the evaluation sought to examine how the multiple systems layers - student, teacher, school, community and government - interacted and influenced each other. A distinguishing feature of the evaluation included 'feedback loops'; that is, evaluation data was provided to participants as it became available. Evaluation tools included a combination of standardised surveys (with pre- and post-intervention data provided to schools via individualised reports), reflection tools, regular reflection interviews and summative focus groups. Results Data was shared during implementation with project staff, department staff and schools to support continuous improvement at these multiple systems levels. In complex settings, implementation can vary according to context; and the impact of evaluation processes, tools and findings differed across the schools. Interviews and focus groups conducted at the end of the project illustrated which of these methods were instrumental in motivating change and engaging stakeholders at both a school and departmental level and why. Conclusion The evaluation methods were a critical component of the pilot's approach, helping to shape implementation through data feedback loops and reflective practice for ongoing, responsive and continuous improvement. Future health promotion research on complex interventions needs to examine how the evaluation itself is influencing implementation. So what? The pilot has demonstrated that the evaluation, including feedback loops to inform project activity, were an

    Full Text Available Irish educational policy acknowledges the importance of integrating technology meaningfully into teaching and learning at the primary level. Much remains to be done, however, in terms of developing, practically implementing and evaluating the use of technology in the Irish primary classroom. This paper describes a study on the use of a structured approach to digital storytelling as a tool for meaningful technology integration with children at primary level. In this study, the researcher developed a structured approach for implementing digital storytelling with primary school children, and collaborated with a class teacher in an Irish primary school to prepare to implement the approach. Multiple qualitative methods were used to evaluate the implementation, including interviews with the teacher, classroom observation, and focus group interviews with participating children. The results suggested that this structured approach to digital storytelling has the potential to be used successfully as a meaningful technology integration approach with this cohort. The findings also explored implications for the implementation of digital storytelling at primary level, and identified aspects on which further research should be undertaken to enhance and extend the approach that was used.

    In the context of inclusive education, so-called «Schulbegleiter» (school escorts) have been installed to assist children with special needs. However, adequate conceptions of their role are lacking, and no provisions exist describing the exact tasks and duties of these school escorts. This article presents data on a statewide empirical study and provides information on the professional background, qualifications, and assignments of such escorts as well as the nature of the assisted children in the German state of Baden-Württemberg. The data were collected in nearly 50 % of all schools providing general education in Baden-Württemberg, and a total of 526 school escorts completed a questionnaire on their work. Children with special needs who received such assistance were aged 6 to 19 years (M = 10.4) and had a mental disorder in nearly three-fourths of all cases, with autism spectrum disorders being most common (59.4 %). The most frequent assignments of the escorts were providing practical assistance during classes and mobilizing the child as well as providing direct support in emotionally challenging situations. Such escorts can make a significant contribution to the inclusive education of disabled children. They do, however, need an adequate qualification and practical competences to meet the diverse challenges of children with special needs. Child and adolescent psychiatrists are supposed to stay involved in the process, not only by planning interventions, but also during the course of inclusive education itself. Thus, the emotional situation and adjustment of included children with mental disorders over time must be monitored adequately.

    The Korean Physical Society (KPS) Women Committee has organized a series of the physics camps for high school girl students to give them an opportunity to work together and interact with professional physicists. Although the KPS Women Committee has successfully set the KPS's face toward women's issues, it still needs more systematic support for helping and promoting the activities of women physicists. We describe the physics camp initiative and present the current status of women in physics in Korea, comparing female ratios in undergraduate and graduate school and faculty for the last ten years (1998-2007). The employment rate for females is compared with that for males according to education level. The total number of female students in physics in Korea has increased; however, it is still a very small portion of females who stay in physics with professional positions.

    The purpose of this article is to describe hypnobehavioral treatment of five school-age children with maladaptive eating behaviors, including functional dysphagia, food aversion, globus hystericus, and conditioned fear of eating (phagophobia). The unique treatment approach described emphasizes the successful use of self-management techniques, particularly hypnosis, by all five children. Common etiological factors, treatment strategies, and proposed mechanisms of change are discussed. To the authors' knowledge, this is the first such case series in the mainstream pediatric literature describing the use of a hypnobehavioral approach for children with these maladaptive eating problems.

    The Biopharmaceutics Classification System (BCS) classifies pharmaceutical compounds based on their aqueous solubility and intestinal permeability. The BCS Class III compounds are hydrophilic molecules (high aqueous solubility) with low permeability across the biological membranes. While these compounds are pharmacologically effective, poor absorption due to low permeability becomes the rate-limiting step in achieving adequate bioavailability. Several approaches have been explored and utilized for improving the permeability profiles of these compounds. The approaches include traditional methods such as prodrugs, permeation enhancers, ion-pairing, etc., as well as relatively modern approaches such as nanoencapsulation and nanosizing. The most recent approaches include a combination/hybridization of one or more traditional approaches to improve drug permeability. While some of these approaches have been extremely successful, i.e. drug products utilizing the approach have progressed through the USFDA approval for marketing; others require further investigation to be applicable. This article discusses the commonly studied approaches for improving the permeability of BCS Class III compounds.

    The high prevalence of overweight among children and adolescents has led to an increase in school-based prevention programmes. The aim of the present paper is to present the concept of an initiative called "BEO'S" as well as the experience made with the implementation und acceptance of this programme in the participating schools. Different from the majority of school-based projects for healthy eating and physical activity, BEO'S pursues a systemic approach that includes the whole school and is tailored to the school's respective resources. Characteristics are (1) the participation of teachers, students, parents, and caretakers, (2) the motivation and empowerment of schools to plan and implement activities by themselves, (3) the focus on environmental approaches, and (4) addressing and considering the individual school's needs and resources. The university project team supports the schools by individual counselling as well as providing information materials, trainings and workshops for teachers, an internet page, newsletters, and financial support. In the school years 2007/08 and 2008/09, BEO'S was conducted at 14 primary and secondary schools in the district of Oberfranken, Bavaria. It was extended to other schools in 2009/10. The short- and mid-term goals are the improvement of the school's environments as well as the eating behaviour and physical activity of the students. In the long run, it is intended to prevent obesity and improve the students' health and school performance. The implementation processes showed that the teachers for physical education and domestic science as well as the headmasters were especially committed. The participation of the teaching staff, the students and the parents proved to be difficult, however. The schools implemented many activities for healthy eating and physical activity, but the planning process was not very systematic: needs assessment, status quo analysis, identification of successful strategies and definition of aims was

  4. Social interactions of eating behaviour among high school students: a cellular automata approach

    Science.gov (United States)

    2012-01-01

    Background Overweight and obesity in children and adolescents is a global epidemic posing problems for both developed and developing nations. The prevalence is particularly alarming in developed nations, such as the United States, where approximately one in three school-aged adolescents (ages 12-19) are overweight or obese. Evidence suggests that weight gain in school-aged adolescents is related to energy imbalance exacerbated by the negative aspects of the school food environment, such as presence of unhealthy food choices. While a well-established connection exists between the food environment, presently there is a lack of studies investigating the impact of the social environment and associated interactions of school-age adolescents. This paper uses a mathematical modelling approach to explore how social interactions among high school adolescents can affect their eating behaviour and food choice. Methods In this paper we use a Cellular Automata (CA) modelling approach to explore how social interactions among school-age adolescents can affect eating behaviour, and food choice. Our CA model integrates social influences and transition rules to simulate the way individuals would interact in a social community (e.g., school cafeteria). To replicate these social interactions, we chose the Moore neighbourhood which allows all neighbours (eights cells in a two-dimensional square lattice) to influence the central cell. Our assumption is that individuals belong to any of four states; Bring Healthy, Bring Unhealthy, Purchase Healthy, and Purchase Unhealthy, and will influence each other according to parameter settings and transition rules. Simulations were run to explore how the different states interact under varying parameter settings. Results This study, through simulations, illustrates that students will change their eating behaviour from unhealthy to healthy as a result of positive social and environmental influences. In general, there is one common characteristic of

    Oral and maxillofacial surgeons who perform orthognathic surgery face major changes in their practices, and these challenges will increase in the near future, because the extraordinary advances in technology applied to our profession are not only amazing but are becoming the standard of care as they promote improved outcomes for our patients. Orthognathic surgery is one of the favorite areas of practicing within the scope of practice of an oral and maxillofacial surgeon. Our own practice in orthognathic surgery has completed over 1,000 surgeries of this type. Success is directly related to the consistency and capability of the surgical-orthodontic team to achieve predictable, stable results, and our hypothesis is that a successful result is directly related to the way we take our records and perform diagnosis and treatment planning following basic general principles. Now that we have the opportunity to plan and treat 3-dimensional (3D) problems with 3D technology, we should enter into this new era with appropriate standards to ensure better results, instead of simply enjoying these new tools, which will clearly show not only us but everyone what we do when we perform orthognathic surgery. Appropriate principles need to be taken into account when implementing this new technology. In other words, new technology is welcome, but we do not have to reinvent the wheel. The purpose of this article is to review the current protocol that we use for orthognathic surgery and compare it with published protocols that incorporate new 3D and virtual technology. This report also describes our approach to this new technology. Copyright © 2011 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc. All rights reserved.

    As indicated by the World Health Organization as of year 2014, around 10,000 people have been influenced with Ebola infection. The episode of Ebola in African locale is courged with a high death rate. Notwithstanding, in the United States, people influenced by Ebola have been given brilliant wellbeing offices, as the U.S. is one of the highest nations that have taken sterner wellbeing measures and principles against Ebola. Aside from the U.S., individuals in Asia, where billions live in indigence and general wellbeing frameworks are frequently extremely powerless, are under more serious danger of the Ebola infection. Despite the fact that nations like Singapore, Malaysia, South Korea and Japan can take stretched out measures to battle against the infection, nations like Philippines and Indonesia have unfathomable quantities of poor who may be incredibly influenced by a conceivable episode. At this moment, the chances that Asia will take a critical hit from the Ebola infection appear to be genuinely little. Yet, while it is far-fetched that Asia will encounter a real flare-up, genuine concerns stay about the infection coming to urban communities like Hong Kong, Beijing, Shanghai and Singapore through their worldwide airplane terminals. Wellbeing priests from the Association of Southeast Asian Nations (ASEAN) reported key measures not long ago to keep the Ebola plague from coming to the locale and to backing influenced nations. This article accordingly will concentrate on the prevalence and current approaches of Ebola Virus Disease in ASEAN nations which is the need of the hour.

    2014-05-01

    As part of the COOPEUS initiative to build infrastructure that connects European and US research infrastructures, IRIS has advocated for the development of Federated services based upon internationally recognized standards using web services. By deploying International Federation of Digital Seismograph Networks (FDSN) endorsed web services at multiple data centers in the US and Europe, we have shown that integration within seismological domain can be realized. By deploying identical methods to invoke the web services at multiple centers this approach can significantly ease the methods through which a scientist can access seismic data (time series, metadata, and earthquake catalogs) from distributed federated centers. IRIS has developed an IRIS federator that helps a user identify where seismic data from global seismic networks can be accessed. The web services based federator can build the appropriate URLs and return them to client software running on the scientists own computer. These URLs are then used to directly pull data from the distributed center in a very peer-based fashion. IRIS is also involved in deploying web services across horizontal domains. As part of the US National Science Foundation's (NSF) EarthCube effort, an IRIS led EarthCube Building Block's project is underway. When completed this project will aid in the discovery, access, and usability of data across multiple geoscienece domains. This presentation will summarize current IRIS efforts in building vertical integration infrastructure within seismology working closely with 5 centers in Europe and 2 centers in the US, as well as how we are taking first steps toward horizontal integration of data from 14 different domains in the US, in Europe, and around the world.

    Community-based dental education (CBDE) enhances students' clinical expertise, improves their cultural competence, increases access to care, and fosters community engagement. As emphasis on CBDE has increased over the last decades, the aim of this survey study was to determine how CBDE is currently being implemented in U.S. dental schools. The study used a 20-item, author-designed survey emailed in April to August 2015 to 60 of the 65 U.S. dental schools, excluding those that had been recently established. Of the 60 schools, representatives of 33 responded, resulting in a 55% response rate: 70% public and 30% private. These respondents reported that the extramural sites being used the most were community clinics (90.9%), Federally Qualified Health Clinics (66.7%), public health clinics (54.5%), and Indian Health Service clinics (42.4%). The majority of responding schools (63.6%) had ten or more sites available for rotations, and the rotation lengths were 1-2 weeks (29%), 2-4 weeks (25%), 4-6 weeks (29%), 6-8 weeks (3.2%), and 8-10 weeks (12.9%). Most of the respondents (78.8%) reported that their students were unable to be assessed for clinical competencies at external clinical sites, but roughly half allowed students to receive clinical credit. After students completed their rotations, the majority of the respondents (81.8%) reported that students were required to produce a reflection, and 87.9% reported that students completed a post-rotation survey. Considering the benefits of CBDE for students' education and for improving access to oral health care, it is encouraging that over 45% of the responding schools required their students to spend four weeks or longer on external rotations.

  11. Teaching science to English Language Learners: Instructional approaches of high school teachers

    Science.gov (United States)

    Frank, Betty-Vinca N.

    Students who are English Language Learners (ELLs) form the fastest growing segment of the American school population. Prompted by the call for scientific literacy for all citizens, science educators too have investigated the intersection of language and science instruction of ELLs. However these studies have typically been conducted with elementary students. Few studies have explored how high school science teachers, particularly those who have not received any special training, approach science instruction of ELLs and what supports them in this endeavor. This was a qualitative case study conducted with five science teachers in one small urban high school that predominantly served ELLs. The purpose of this study was to examine instructional approaches used by teachers to make science accessible to ELLs and the factors that supported or inhibited them in developing their instructional approaches. This goal encompassed the following questions: (a) how teachers viewed science instruction of ELLs, (b) how teachers designed a responsive program to teach science to ELLs, (c) what approaches teachers used for curriculum development and instruction, (d) how teachers developed classroom learning communities to meet the needs of ELLs. Seven instructional strategies and five perceived sources of support emerged as findings of this research. In summary, teachers believed that they needed to make science more accessible for their ELL students while promoting their literacy skills. Teachers provided individualized attention to students to provide relevant support. Teachers engaged their students in various types of active learning lessons in social contexts, where students worked on both hands-on and meaning-making activities and interacted with their peers and teachers. Teachers also created classroom communities and learning spaces where students felt comfortable to seek and give help. Finally, teachers identified several sources of support that influenced their instructional

    TakaH

    2002-01-01

    This presentation aims to overview the current status and perspective of behavioral approaches used in guideline-oriented toxicological studies for agricultural chemicals.Guidelines revised recently (MAFF,OECD,EPA) require sytematic observation of non-learning behavior using defined scales.The observational endpoints are organized into a battery (e.g.functional observational battery,FOB) and inculde home-cage and open-field observation of behavior reactivity to various stimuli(e.g.auditory,tactile,visual),grip strength,and motor activity under a novel environment.The outline of FOB will be illustrated and discussed in the first half of the presentation.One social concern in neurotoxicology is the impact of chemical exposure on cnognitive functions such as learning and memory as well as non-learning behavior.Guidelines describe the necessity of learning and memory tests when other data suggest potential effects on brain function,even though little information regarding cognitive status other than brain pathology can be obtained with FOB.This discrepancy arises from the lack of a simple method compatible with regular studies.One candidate method is fear-induced freezing of rats conditioned to context and auditory cue(Kim & Fanselow,1992).In order to evaluate this paradigm as a screening method,the effects of trimethyltin chloride (TMT) have been studied.Prior to the study,it has been characterized that oral administration of TMT to rats produces excitatory clinical signs and massive neural cell death in the hippocampal CA1 and CA3 regions at lethal dose(8mg·kg-1),but not any abnormalities at sub-lethal doses (4mg·kg-1 or less).Oral administration of TMT at a sub-lethal dose produced a significant decrease in freezing time to the context (hippocampal-dependent measure),but not to the auditory cue.Administration of TMT at a sublethal dose significantly inhibited long-term potentiation in the CA1,but not in the dentate gyrus.These results suggest that the model can be

    The aim of this study was to investigate the approach and behaviour of middle school students in Catania, towards the risks associated with tobacco smoke. This study is part of a multicentric project evaluating the lifestyles of middle school students (grades 6-8), carried out by the Research and Health Education Group (GRES) and was performed during the 2006/2007 school year. In total 432 students participated in the study by completing a self-administered questionnaire. Data was analysed by using the Statistical Package for the Social Sciences (SPSS). Results show an increasing trend in the number of smokers from grades 6 to 8. In grades 6 and 8 most smokers are female while in grade 7 male smokers outnumber female smokers. Three percent of the student population reports smoking occasionally and 3% are regular smokers. In light of these results families, schools and institutions should take charge of programming and implementing health promotion interventions aimed at reducing risks and improving the quality of life of students in Catania.

    Georgia Hall

    2015-06-01

    Full Text Available Opportunity to participate in an out-of-school time program may be a meaningful support mechanism towards school success and healthy development for immigrant and refugee children. This study extends existing research on best practices by examining the on-the-ground experiences of supporting immigrant and refugee youth in out-of-school time programs. Findings from semi-structured interviews with program directors in 17 Massachusetts and New Hampshire programs suggest a number of program strategies that were responsive to the needs of immigrant and refugee students, including support for the use of native language as well as English, knowing about and celebrating the heritage of the students’ homeland, including on staff or in leadership individuals with shared immigrant background, and giving consideration to the academic priorities of parents. The development of such intentional approaches to working with immigrant and refugee youth during the out-of-school time hours will encourage enrollment of, and enhance effectiveness with, this vulnerable population.

    The transition from pre-school to kindergarten can be complex for children who need special assistance due to mental or physical disabilities (children with 'special needs'). We used a convergent mixed method approach to explore parents' experiences with service provision as their children transitioned to school. Parents (including one grandparent) of 37 children aged 4 to 6 years completed measures assessing their perceptions of and satisfaction with services. Semi-structured interviews were also conducted with 10 parents to understand their experience with services. Post transition, parents reported lower perceptions of services and decreased satisfaction than pre-transition. The following themes emerged from the qualitative data: qualities of services and service providers, communication and information transfer, parent advocacy, uncertainty about services, and contrasts and contradictions in satisfaction. The qualitative findings indicate that parents were both satisfied and concerned with aspects of the post-transition service provision. While the quantitative results suggested that parents' experience with services became less positive after their children entered school, the qualitative findings illustrated the variability in parents' experiences and components of service provision that require improvements to facilitate a successful school entry. © 2017 John Wiley & Sons Ltd.

    The aim of the research was to gain increased knowledge regarding the sexual risk behaviour of school-going young people in South Africa after two decades of HIV-education in schools, to contribute to the development of improved HIV prevention strategies. In collaboration with the Department of Education, a sample of 5305 learners (between 10 and 18 years in Grades 5-12) from high-risk communities were identified. They completed a survey that assessed self-reported sexual risk behaviour and variables that potentially underlie sexual risk, such as attitudes towards preventive behaviour, perceived social norms and self-efficacy (based on the theory of planned behaviour [TPB]) and social factors like caregiver relationships and gender norms (based on the social ecological theory). Lifetime sex was reported by 49.4% of boys and 30.5% of girls in Grades 8-12, while 56% of the sexually active young people reported consistent condom use. Accurate knowledge about HIV transmission was low (37.8%). Regression analysis showed that risk behaviour was more prominent among older male youths, who perceived social norms as encouraging sexual activity, who use alcohol excessively, and who have negative attitudes towards abstinence. Perceived traditional community gender norms and negative relationships with caregivers were also associated with sexual risk behaviour. This research showed that the TPB can be used in planning HIV prevention interventions for young people. It also revealed that HIV-prevention strategies should focus beyond educating the individual, to address community factors such as improving caregiver relationships, the culture of substance abuse, peer group norms and inequality in community gender norms. These community processes influence young people's behaviour and need to be addressed to allow the youth to make healthy behavioural choices.

    2016-09-01

    Full Text Available In this study, the pedagogical content knowledge (PCK of four experienced primary school teachers was investigated within the “Let’s Solve the Riddle of Our Body Unit”. The PCK investigation adopted a learning approach based on inquiry, content representation and pedagogical and professional-experience repertoires (PaP-eRs, and interview forms were used as data collection tools. During the course of the research, the findings obtained from observations made during a total of 18 course hours formed the basic data source of the study. According to the results of the study, in which descriptive and content analysis were used concurrently, primary school teachers lack subject matter knowledge, do not interrogate the pre-knowledge of students and some misconceptions exist regarding about blood moves and exercise with pulse. Additionally, some deficiencies were detected in the curriculum, i.e., it offers non-inquisitional knowledge. Furthermore, teachers employee assessment methods with traditional teaching methods and techniques. In the context of an inquiry-based learning approach, teachers appeared to believe that classroom activities were adversely affected by the physical conditions (class size, lack of laboratory etc., students’ cognitive levels and parent profiles. The result of this study revealed that PCK components affect one another. The PCK findings pertaining to primary school teachers as it concerns the unit are briefly discussed and some suggestions about the development of PCK are submitted.

    This formative evaluation develops a novel conceptual model for a discipline approach fostering intrinsic motivation and positive relationships in schools. We used concept mapping to elicit and integrate perspectives on kind discipline from teachers, administrators, and other school staff. Three core themes describing kind discipline emerged from 11 identified clusters: (1) proactively developing a positive school climate, (2) responding to conflict with empathy, accountability, and skill, and (3) supporting staff skills in understanding and sharing expectations. We mapped the identified components of kind discipline onto a social ecological model and found that kind discipline encompasses all levels of that model including the individual, relational, environmental/structural, and even community levels. This contrasts with the dominant individual-behavioral discipline approaches that focus on fewer levels and may not lead to sustained student and staff motivation. The findings illustrate the importance of setting and communicating clear expectations and the need for them to be collaboratively developed. Products of the analysis and synthesis reported here are operationalized materials for teachers grounded in a "be kind" culture code for classrooms. Copyright © 2017 Elsevier Ltd.

    2016-04-01

    Full Text Available Students’ attitudes and approaches to physics problem solving can impact how well they learn physics and how successful they are in solving physics problems. Prior research in the U.S. using a validated Attitude and Approaches to Problem Solving (AAPS survey suggests that there are major differences between students in introductory physics and astronomy courses and physics experts in terms of their attitudes and approaches to physics problem solving. Here we discuss the validation, administration, and analysis of data for the Turkish version of the AAPS survey for high school and university students in Turkey. After the validation and administration of the Turkish version of the survey, the analysis of the data was conducted by grouping the data by grade level, school type, and gender. While there are no statistically significant differences between the averages of various groups on the survey, overall, the university students in Turkey were more expertlike than vocational high school students. On an item by item basis, there are statistically differences between the averages of the groups on many items. For example, on average, the university students demonstrated less expertlike attitudes about the role of equations and formulas in problem solving, in solving difficult problems, and in knowing when the solution is not correct, whereas they displayed more expertlike attitudes and approaches on items related to metacognition in physics problem solving. A principal component analysis on the data yields item clusters into which the student responses on various survey items can be grouped. A comparison of the responses of the Turkish and American university students enrolled in algebra-based introductory physics courses shows that on more than half of the items, the responses of these two groups were statistically significantly different, with the U.S. students on average responding to the items in a more expertlike manner.

    Full Text Available Conceptual maps are representations of ideas organized in the form of bidimensional diagrams. In the present work the theme of oil fractional distillation was explored, and the conceptual maps were elaborated both before and after the activities by 43 students from the 1st and 3rd High School grades of a public school in Londrina – PR. The study was conducted theoretically and in practice, with a daily life approach. The use of the motivational theme and the opening text as previous organizers, enabled the establishment of a cognitive link between the students’ previous knowledge and the new concepts. Differences between the maps were verified before and after the activities as well as among the work groups. The students, stimulated by the technique, created better structured maps.

    2013-10-01

    This qualitative study used the grounded theory approach to analyze digital textbook-related health experiences of school-age children. In-depth interviews were held with 40 elementary school students who had used digital textbooks for at least a year. Data analysis revealed a total of 56 concepts, 20 subcategories, and 11 categories related to digital textbook health issues, the central phenomena being "health-related experiences." Students' health-related experiences were classified into "physical" and "psychological" symptoms. Adverse health effects related to digital textbook usage were addressed via both "student-led" and "instructor-led" coping strategies. Students' coping strategies were often inefficient, but instructor-led strategies seemed to prevent health problems. When health issues were well managed, students tended to accept digital textbooks as educational tools. Our findings suggest that students can form healthy computer habits if digital textbook usage is directed in a positive manner.

    1995-06-01

    Motivated by cosmological applications like electroweak baryogenesis, we develop a field theoretic approach to the computation of particle currents on a space-time dependent and CP-violating Higgs background. We consider the Standard Model model with two Higgs doublets and CP violation in the scalar sector, and compute both fermionic and Higgs currents by means of an expansion in the background fields. We discuss the gauge dependence of the results and the renormalization of the current operators, showing that in the limit of local equilibrium, no extra renormalization conditions are needed in order to specify the system completely.

    2010-05-01

    In this paper we present the current state of cultural diversity education for undergraduate medical students in three English-speaking countries: the United Kingdom (U.K.), United States (U.S.) and Canada. We review key documents that have shaped cultural diversity education in each country and compare and contrast current issues. It is beyond the scope of this paper to discuss the varied terminology that is immediately evident. Suffice it to say that there are many terms (e.g. cultural awareness, competence, sensitivity, sensibility, diversity and critical cultural diversity) used in different contexts with different meanings. The major issues that all three countries face include a lack of conceptual clarity, and fragmented and variable programs to teach cultural diversity. Faculty and staff support and development, and ambivalence from both staff and students continue to be a challenge. We suggest that greater international collaboration may help provide some solutions.

    Full Text Available The Alberta Project Promoting active Living and healthy Eating in Schools (APPLE Schools has been recognized as a "best practice" in preventing childhood obesity. To inform decision making on the economic implications of APPLE Schools and to justify investment, we evaluated the project's cost-effectiveness following a life-course approach.We developed a state transition model for the lifetime progression of body weight status comparing elementary school students attending APPLE Schools and control schools. This model quantified the lifetime impact of APPLE Schools in terms of prevention of excess body weight, chronic disease and improved quality-adjusted life years (QALY, from a school system's cost perspective. Both costs and health outcomes were discounted to their present value using 3% discount rate.The incremental cost-effectiveness ratio(ICER of APPLE schools was CA$33,421 per QALY gained, and CA$1,555, CA$1,709 and CA$14,218 per prevented person years of excess weight, obesity and chronic disease, respectively. These estimates show that APPLE Schools is cost effective at a threshold of ICER < CA$50,000. In probabilistic sensitivity analysis, APPLE Schools was cost effective more than 64% of the time per QALY gained, when using a threshold of ICERSchool-based health promotion, such as APPLE Schools is a cost-effective intervention for obesity prevention and reduction of chronic disease risk over the lifetime. Expanding the coverage and allocating resources towards school-based programs like the APPLE Schools program, is likely to reduce the public health burden of obesity and chronic diseases.

  20. The current approach to human error and blame in the NHS.

    Science.gov (United States)

    Ottewill, Melanie

    There is a large body of research to suggest that serious errors are widespread throughout medicine. The traditional response to these adverse events has been to adopt a 'person approach' - blaming the individual seen as 'responsible'. The culture of medicine is highly complicit in this response. Such an approach results in enormous personal costs to the individuals concerned and does little to address the root causes of errors and thus prevent their recurrence. Other industries, such as aviation, where safety is a paramount concern and which have similar structures to the medical profession, have, over the past decade or so, adopted a 'systems' approach to error, recognizing that human error is ubiquitous and inevitable and that systems need to be developed with this in mind. This approach has been highly successful, but has necessitated, first and foremost, a cultural shift. It is in the best interests of patients, and medical professionals alike, that such a shift is embraced in the NHS.

  4. Off-equatorial current-driven instabilities ahead of approaching dipolarization fronts

    Science.gov (United States)

    Zhang, Xu; Angelopoulos, V.; Pritchett, P. L.; Liu, Jiang

    2017-05-01

    Recent kinetic simulations have revealed that electromagnetic instabilities near the ion gyrofrequency and slightly away from the equatorial plane can be driven by a current parallel to the magnetic field prior to the arrival of dipolarization fronts. Such instabilities are important because of their potential contribution to global electromagnetic energy conversion near dipolarization fronts. Of the several instabilities that may be consistent with such waves, the most notable are the current-driven electromagnetic ion cyclotron instability and the current-driven kink-like instability. To confirm the existence and characteristics of these instabilities, we used observations by two Time History of Events and Macroscale Interactions during Substorms satellites, one near the neutral sheet observing dipolarization fronts and the other at the boundary layer observing precursor waves and currents. We found that such instabilities with monochromatic signatures are rare, but one of the few cases was selected for further study. Two different instabilities, one at about 0.3 Hz and the other at a much lower frequency, 0.02 Hz, were seen in the data from the off-equatorial spacecraft. A parallel current attributed to an electron beam coexisted with the waves. Our instability analysis attributes the higher-frequency instability to a current-driven ion cyclotron instability and the lower frequency instability to a kink-like instability. The current-driven kink-like instability we observed is consistent with the instabilities observed in the simulation. We suggest that the currents needed to excite these low-frequency instabilities are so intense that the associated electron beams are easily thermalized and hence difficult to observe.

  13. Rotor cage fault diagnosis in three-phase induction motors based on a current and virtual flux approach

    International Nuclear Information System (INIS)

    Pires, Dulce F.; Pires, V. Fernao; Martins, J.F.; Pires, A.J.

    2009-01-01

    This paper focuses on the detection of a rotor cage fault in a three-phase PWM feed induction motor. In inverter-fed machines there are some difficulties for the detection of a rotor cage fault. These difficulties are due to the fault signature that will be contained in the currents or voltages applied to the machine. In this way, a new approach based on the current and a virtual flux is proposed. The use of the virtual flux allows the improving of the signal to noise ratio. This approach also allows the identification of a rotor cage fault independently of the type of control used in the ac drive. The theoretical principle of this method is discussed. Simulation and experimental results are presented in order to show the effectiveness of the proposed approach

    2016-02-01

    To identify the share of open access (OA) papers in the total number of journal publications authored by the members of the University of Zagreb School of Medicine (UZSM) in 2014. Bibliographic data on 543 UZSM papers published in 2014 were collected using PubMed advanced search strategies and manual data collection methods. The items that had "free full text" icons were considered as gold OA papers. Their OA availability was checked using the provided link to full-text. The rest of the UZSM papers were analyzed for potential green OA through self-archiving in institutional repository. Papers published by Croatian journals were particularly analyzed. Full texts of approximately 65% of all UZSM papers were freely available. Most of them were published in gold OA journals (55% of all UZSM papers or 85% of all UZSM OA papers). In the UZSM repository, there were additional 52 freely available authors' manuscripts from subscription-based journals (10% of all UZSM papers or 15% of all UZSM OA papers). The overall proportion of OA in our study is higher than in similar studies, but only half of gold OA papers are accessible via PubMed directly. The results of our study indicate that increased quality of metadata and linking of the bibliographic records to full texts could assure better visibility. Moreover, only a quarter of papers from subscription-based journals that allow self-archiving are deposited in the UZSM repository. We believe that UZSM should consider mandating all faculty members to deposit their publications in UZSM OA repository to increase visibility and improve access to its scientific output.

  16. A new approach to control a deflection of an electroplated microstructure: dual current electroplating methods

    International Nuclear Information System (INIS)

    Yang, Hyun-Ho; Seo, Min-Ho; Han, Chang-Hoon; Yoon, Jun-Bo

    2013-01-01

    We propose and demonstrate a simple and novel method to control the deflection in a suspended microstructure by using a dual current electroplating (DuCE) method. The key concept of this method is to divide the structure into two layers—a bottom layer and a top layer—and then apply respective current densities in electroplating to those two layers while all other conditions are kept the same. In addition to a flat structure, the direction of structure bending is freely controlled by virtue of the DuCE method. Cantilever Ni beams with a length of 400 µm, which were electroplated by the conventional single current electroplating method, bent downward with a deflection of 3.4 µm. On the contrary, by the DuCE method, cantilever beams with a length of 400 µm showed an almost flat structure as desired. (The current densities of the bottom layer, the top layer, and the ratio of the two current densities, are 0.15, 1.24 A dm −2 , and 8.3, respectively.) Consequently, a nickel electroplated spiral structure with a length of 8600 µm was suspended flat with an end deflection of less than 0.7 µm (the ratio between the deflection and length is 0.007%). This work therefore represents the unprecedented ultra-long suspended microstructure with submicrometer deflection. (paper)

  17. Cognitive-behavior therapy for problem gambling: a critique of current treatments and proposed new unified approach.

    2017-06-01

    There is evidence supporting the use of cognitive-behavioral therapy (CBT) in the treatment of problem gambling. Despite this, little is known about how CBT works and which particular approach is most effective. This paper aims to synthesize the evidence for current CBT and propose a more unified approach to treatment. A literature review and narrative synthesis of the current research evidence of CBT for the treatment of problem gambling was conducted, focusing on the underlying mechanisms within the treatment approach. Several CBT approaches were critiqued. These can be divided into forms of exposure therapy (including aversion techniques, systematic desensitization and other behavioral experiments) those focusing on cognitive restructuring techniques (such as reinforcement of nongambling activity, use of diaries, motivational enhancement and audio-playback techniques and third wave techniques including mindfulness. Findings, in relation to the treatment actions, from this synthesis are reported. The debate surrounding the treatment of problem gambling has been conducted as an either/or rather than a both/and discourse. This paper proposes a new, unified approach to the treatment of problem gambling that incorporates the best elements of both exposure and cognitive restructuring techniques, alongside the use of techniques borrowed from mindfulness and other CBT approaches.

    The Alberta Project Promoting active Living and healthy Eating in Schools (APPLE Schools) has been recognized as a "best practice" in preventing childhood obesity. To inform decision making on the economic implications of APPLE Schools and to justify investment, we evaluated the project's cost-effectiveness following a life-course approach. We developed a state transition model for the lifetime progression of body weight status comparing elementary school students attending APPLE Schools and control schools. This model quantified the lifetime impact of APPLE Schools in terms of prevention of excess body weight, chronic disease and improved quality-adjusted life years (QALY), from a school system's cost perspective. Both costs and health outcomes were discounted to their present value using 3% discount rate. The incremental cost-effectiveness ratio(ICER) of APPLE schools was CA$33,421 per QALY gained, and CA$1,555, CA$1,709 and CA$14,218 per prevented person years of excess weight, obesity and chronic disease, respectively. These estimates show that APPLE Schools is cost effective at a threshold of ICER Schools was cost effective more than 64% of the time per QALY gained, when using a threshold of ICERSchool-based health promotion, such as APPLE Schools is a cost-effective intervention for obesity prevention and reduction of chronic disease risk over the lifetime. Expanding the coverage and allocating resources towards school-based programs like the APPLE Schools program, is likely to reduce the public health burden of obesity and chronic diseases.

    Goudet, B

    1999-03-01

    Violence is present in all forms of society that impose limits that must not be surpassed (murder, incest ...) in order for social life to be possible. But these limits are always broken. Youth are, in this respect, in a difficult situation, especially those from marginalized areas. Victims of contempt and exclusion, they react through violent acts; to violence experienced because of excessive constraints in school, they respond with violence. This juvenile violence calls for macro-social responses that return credibility to the institutional system often corrupt and responsible for hidden social violence. It also calls for micro-social actions, especially within the community. These actions may allow for awareness of violence generating phenomena, the discovery of obstacles to exercising rights, and the make-up of conflicts and their resolution in negotiation procedures.

  7. 3-D time-domain induced polarization tomography: a new approach based on a source current density formulation

    Science.gov (United States)

    Soueid Ahmed, A.; Revil, A.

    2018-04-01

    Induced polarization (IP) of porous rocks can be associated with a secondary source current density, which is proportional to both the intrinsic chargeability and the primary (applied) current density. This gives the possibility of reformulating the time domain induced polarization (TDIP) problem as a time-dependent self-potential-type problem. This new approach implies a change of strategy regarding data acquisition and inversion, allowing major time savings for both. For inverting TDIP data, we first retrieve the electrical resistivity distribution. Then, we use this electrical resistivity distribution to reconstruct the primary current density during the injection/retrieval of the (primary) current between the current electrodes A and B. The time-lapse secondary source current density distribution is determined given the primary source current density and a distribution of chargeability (forward modelling step). The inverse problem is linear between the secondary voltages (measured at all the electrodes) and the computed secondary source current density. A kernel matrix relating the secondary observed voltages data to the source current density model is computed once (using the electrical conductivity distribution), and then used throughout the inversion process. This recovered source current density model is in turn used to estimate the time-dependent chargeability (normalized voltages) in each cell of the domain of interest. Assuming a Cole-Cole model for simplicity, we can reconstruct the 3-D distributions of the relaxation time τ and the Cole-Cole exponent c by fitting the intrinsic chargeability decay curve to a Cole-Cole relaxation model for each cell. Two simple cases are studied in details to explain this new approach. In the first case, we estimate the Cole-Cole parameters as well as the source current density field from a synthetic TDIP data set. Our approach is successfully able to reveal the presence of the anomaly and to invert its Cole

    2015-01-01

    Full Text Available During geomagnetic disturbances, the telluric currents which are driven by the induced electric fields will flow in conductive Earth. An approach to model the Earth conductivity structures with lateral conductivity changes for calculating geoelectric fields is presented in this paper. Numerical results, which are obtained by the Finite Element Method (FEM with a planar grid in two-dimensional modelling and a solid grid in three-dimensional modelling, are compared, and the flow of induced telluric currents in different conductivity regions is demonstrated. Then a three-dimensional conductivity structure is modelled and the induced currents in different depths and the geoelectric field at the Earth’s surface are shown. The geovoltages by integrating the geoelectric field along specific paths can be obtained, which are very important regarding calculations of geomagnetically induced currents (GIC in ground-based technical networks, such as power systems.

    Science.gov (United States)

    Dishion, T J; Kavanagh, K

    2000-01-01

    The Adolescent Transitions Program (ATP) is a multilevel approach to family-based interventions within a middle-school setting. The intervention strategy is based on an ecological framework for studying social and emotional development in children and adolescents, emphasizing a network of contextual factors within which parenting is both directly and indirectly influential on the development of problem behavior. The ATP model includes a universal, selected, and indicated strategy for serving families with young adolescents. The model is designed to address the needs of families of young adolescents that present with a range of problem behavior and diverse developmental histories. The three interventions levels are described, and outcome data are presented, that support the effectiveness of the ATP model. This approach and the associated data are consistent with a broad literature supporting the effectiveness of family interventions, especially for high-risk youth. The effective implementation of family interventions within a school context suggests that these interventions can make a significant contribution to reducing problem behavior and substance use from a public health perspective.
