    Objetivo: Evaluación de la efectividad y seguridad de la fampridina en la mejoría de la marcha de pacientes adultos con esclerosis múltiple.Método: Estudio descriptivo retrospectivo de todos los pacientes que iniciaron tratamiento con fampridina entre marzo de 2014 y febrero de 2015. Se evaluó la efectividad utilizando el test de marcha de los 25 pies y la escala de movilidad de 12 ítems de la esclerosis múltiple. Se revisó si los pacientes habían sufrido alguno de los efectos adversos más frecuentes descritos en el ensayo pivotal.Resultados: Se incluyeron 6 pacientes, con una tasa de respuesta del 66,7%. A los 3-6 meses, el cambio medio en la velocidad de la marcha (comparado con el basal) fue del 39,32% y hubo una mejora media de 15 puntos en la escala de movilidad. Solo uno de los pacientes presentó efectos adversos. Conclusiones: Los resultados obtenidos son esperanzadores, sobre todo cuando la fampridina es el único fármaco autorizado actualmente para controlar un síntoma tan discapacitante como es la inestabilidad de la marcha.

    Persons with MS (PwMS) commonly present ambulatory and manual dysfunctions. While ambulation is recognized as important to PwMS, manual dysfunction is only lately gaining attention. Fampridine-PR was approved for MS ambulatory impairments. Anecdotal evidences indicate possible therapeutic effects on manual function. To comprehensively assess the effect of Fampridine-PR on manual functions of PwMS. Twenty six PwMS with ambulatory and manual dysfunction assessed before, 1 and 3months after treatment with Fampridine-PR, applying Timed 25-Foot Walk (T25FW) for ambulation while manual functions were evaluated by several tools addressing the International Classification of Functioning (ICF) concepts. This includes hand grip and pinch strength, 9 Hole Peg Test (9HPT), Arthritis Hand Function Test (AHFT), activities of daily life (ADL) tests, ABILHAND questionnaire and Computerized Penmanship Evaluation Tool (ComPET). Fampridine-PR increased dominant hand grip and pinch strength 1month following treatment initiation by 12% and 10% (pPR improves manual function of PwMS. Methods herein indicate that an integrative approach may be useful for evaluation of manual function in MS and in additional neurological diseases. Copyright © 2015 Elsevier B.V.

    Gait impairment, a frequent sign in multiple sclerosis (MS), places a major burden on patients since it results in progressive loss of personal and social autonomy, along with work productivity. This guide aims to provide recommendations on how to evaluate gait impairment and use prolonged-release fampridine (PR-fampridine) as treatment for MS patients with gait impairment in Spain. PR-fampridine dosed at 10mg every 12hours is currently the only drug approved to treat gait impairment in adults with MS. Additionally, PR-fampridine has been shown in clinical practice to significantly improve quality of life (QoL) in patients who respond to treatment. Treatment response can be assessed with the Timed 25-Foot Walk (T25FW) or the 12-item MS Walking Scale (MSWS-12); tests should be completed before and after starting treatment. The minimum time recommended for evaluating treatment response is 2 weeks after treatment onset. Patients are considered responders and permitted to continue the treatment when they demonstrate a decrease in their T25FW time or an increase in MSWS-12 scores. A re-evaluation is recommended at least every 6 months. The SF-36 (Short Form-36) and the MSIS-29 (MS Impact Scale-29) tests are recommended for clinicians interested in performing a detailed QoL assessment. This drug is generally well-tolerated and has a good safety profile. It should be taken on an empty stomach and renal function must be monitored regularly. These recommendations will help ensure safer and more efficient prescription practices and easier management of PR-fampridine as treatment for gait impairment in Spanish adults with MS.

    2017-01-01

    Cognitive fatigue (CF) is a common complaint in persons with MS (PwMS). Fampridine-SR improves ambulation, fatigue and endurance, due to enhancing action potential formation by blocking potassium channels in demyelinated axons. Thus, through this same mechanism, it is hypothesized that Fampridine-SR could improve CF. To determine if Fampridine-SR objectively improves CF in PwMS. Sixty PwMS of any type with CF, defined as 3 or less correct responses when comparing the last third to the first third on the Paced Auditory Serial Addition Test (PASAT), were recruited from a tertiary care MS clinic in London (ON) Canada. Subjects also had to be between 18 and 64 years of age, inclusive, not had a relapse in the last 60 days or corticosteroids in the last 30 days, EDSS 0.0-7.0, and no other diagnosis that could cause cognitive impairment. A randomized double blind crossover design was used: subjects were randomized to either placebo or Fampridine-SR for 4 weeks, then after at least a one week washout, received the opposite treatment. Subjects were assessed before and after each treatment block. The primary outcome was the PASAT CF score after treatment with Fampridine-SR compared to placebo. T-tests and chi-square were used to compare demographics between the two groups (placebo-Fampridine-SR vs. Fampridine SR-placebo). Treatment effects were assessed using factorial ANOVA, with treatment (Fampridine-SR vs. placebo) and time (before and after treatment) as within-subject variables. Of the 60 subjects randomized, 48 completed the study; three were removed due to an adverse event while in the treatment arm (one due to relapse while on placebo, one due to urinary retention and one due to dizziness and headache while on Fampridine-SR). The subjects had a mean age of 46.5±10.0 years, education of 13.6±1.9 years, and were diagnosed with MS 10.6±9.6 years ago. The majority were female (46, 76.7%), had relapsing remitting MS (41, 68.3%) with median EDSS of 3.5 (range 1

Patients and methods: MS patients with walking impairment deemed candidates for treatment with PR-fampridine tablets were included in this case series. Clinical assessments included the Expanded Disability Status Scale (EDSS, Timed 25-Foot Walk (T25FW, 12-item Multiple Sclerosis Walking Scale (MSWS-12, EuroQoL-5D, and the Fatigue Severity Scale (FSS. The T25FW was videotaped at each visit. Assessments were performed at baseline and after 4 weeks of treatment with PR-fampridine tablets 10 mg twice daily. Clinical benefit of treatment was defined as any improvement in T25FW or MSWS-12 score at 4 weeks. Patients who demonstrated clinical benefit continued treatment and were assessed at 3 and 6 months. Results: Among all patients (N = 67; mean MS duration, 16.5 years; mean EDSS score, 4.8; mean T25FW, 13.9 seconds, 65, 52, and 48 completed the 4-week, 3-month, and 6-month visits, respectively. After 4 weeks, 50.7% and 32.8% of patients walked ≥10% and ≥20% faster, respectively; and in 65.7% of patients, MSWS-12 scores improved. Three patients experienced adverse events (nausea, n = 2, insomnia, n = 1 that resulted in discontinuation of treatment. After 6 months, 38.8% and 16.4% of patients walked ≥10% and ≥20% faster versus baseline, respectively; and in 59.7% of patients, MSWS-12 scores improved. Among patients who demonstrated clinical benefit of treatment at 6 months, FSS scores improved on average by 1 point and MSWS-12 scores by 10 points.

    The aim of the present study was to understand the nature of teaching efficacy beliefs related to a socioscientific issue (SSI). We investigated Turkish preservice science teachers' teaching efficacy beliefs about genetically modified (GM) foods using a belief system approach. We assumed that preservice teachers' beliefs about GM foods (content knowledge, risk perceptions, moral beliefs, and religious beliefs) and their teaching efficacy beliefs about this topic constitute a belief system, and these beliefs are interrelated due to core educational beliefs. We used an exploratory mixed design to test this model. We developed and administered specific questionnaires to probe the belief system model. The sample for the quantitative part of this study included 441 preservice science teachers from eight universities. We randomly selected eight participants in this group for follow-up interviews. The results showed that preservice science teachers held moderately high teaching efficacy beliefs. Learning and teaching experiences, communication skills, vicarious experiences, emotional states, and interest in the topic were sources of this efficacy. In addition, content knowledge and risk perceptions were predictors of teaching efficacy. We believe that epistemologies based on traditional teaching and the values attached to science teaching are the core beliefs that affect the relationship between predictor variables and teaching efficacy.

  12. The safety and efficacy issues of progestin-only oral contraceptives--an epidemiologic perspective.

    Progestogen-only oral contraceptives (POCs) are generally considered a good contraceptive choice for brestfeeding women and for women who want to use an oral form of contraception, but are not suited for, or cannot tolerate the side effects of, estrogen-containing preparations. However, a number of POCs' safety, efficacy and other related issues remain to be addressed. This paper reviews recent literature and evaluates these issues from an epidemiologic perspective. The small number of users imposes severe limitations in designing epidemiologic studies to address POCs' long-term safety issues, but available information suggests POCs are at least as safe as, if not safer than, COCs. Compared to COCs, POCs are more likely to cause menstrual disturbances which, in turn, could affect their acceptability and lead to poor compliance and hence higher pregnancy rates. POCs' efficacy has been estimated to be between 1.4 and 4.3 pregnancies per 100 woman-years of use. Lower pregnancy rates approaching those of COCs have been reported in centers with good counseling. POCs' benefits outweigh their risks. However, more studies are needed to further address POCs' safety and efficacy issues.

    Full Text Available A selective and high-throughput liquid chromatography–mass spectrometry method has been developed and validated for the simultaneous quantification of paroxetine, fampridine, and quinidine in rat plasma using imipramine as an internal standard. Following protein precipitation extraction, the analytes and internal standard were run on XBridge C18 column (150 mm × 4.6 mm, 5 μm using a gradient mobile phase consisting of 5mM ammonium formate in water (pH 9.0 and acetonitrile in a flow gradience program. The precursor and product ions of the drugs were monitored on a triple quadrupole instrument operated in the positive ionization mode. The method was validated over a concentration range of 0.1–100 ng/mL for all the three analytes, with relative recoveries ranging from 69% to 82%. The intra- and interbatch precision (percent coefficient of variation across four validation runs were less than 13.4%. The accuracy determined at four quality control (QC levels (lower limit of quantitation, low QC, medium QC, and high QC was within ±6.5% of coefficient of variation values. The method proved highly reproducible and sensitive, and was successfully applied in a pharmacokinetic study after single-dose oral administration to rats and also in perfusion study sample analysis.

    Full Text Available Hodgkin’s lymphoma (HL is highly sensitive to chemo- and radiotherapy. Long-term tumor-free survival in patients with early stages is close to 95–98 %. Therapy results in patients with advanced stages is worse that requires an intensification of treatment and creates the issuesof late toxicity prevention. These problems are especially relevant in young adults with a life expectancy of 40 years or more. Escalated BEACOPP protocol developed by the German study group allows to achieve cure the majority of patients with advanced-stage Hodgkin’s lymphoma, but this regime has significant toxicity. It causes infertility in almost all patients. BEACOPP-14 with comparable activity contains less cumulative doses of potentially gonadotoxic alkylating agents. Efficacy and toxicity of this regime has been analyzed in 29 patients with prognostically unfavorable stages of HL (m – 13, f – 16 received 8 courses BEACOPP-14 without a dose reduction of cytostatics. The median age of patients was 24 (20–35 years. With a median follow-up of 32.8 (4–66 months, event-free survival was 92.8 %, disease-free – 96.2 %, and overall survival – 95.2 %. Of the 16 women included in the study, the menstrual cycle was restored in 14 patients during 3–6 months. 2 patients were not evaluated because of switch to more intensive chemotherapy in the early stages of treatment. Of the remaining 14 patients pregnancy occurred in 3 (18.7 %, delivery – in 2, abortion – in 1. Delivery was term, children born healthy. Most of the patients according to the doctors’ recommendations protects and continues to avoid pregnancy for 2 years after treatment. The data indicate a potentially less reproductive damaging of BEACOPP-14 in females retaining high anti-tumor efficacy.

    Allogeneic BMT represents the only chance of cure for beta-thalassemia. Occasionally, two affected individuals from the same family share a matched healthy sibling. Moreover, a high incidence of transplant rejection is still observed in Pesaro class III patients, requiring a second BMT procedure. In these settings, one option is to perform a second BM harvest from the same donor. Although BM harvest is a safe procedure in children, ethical issues concerning this invasive practice still arise. Here, we describe our series of seven pediatric, healthy donors, who donated BM more than once in favor of their beta-thalassemic HLA-identical siblings between June 2005 and January 2008. Three donors donated BM twice to two affected siblings and four donors donated twice for the same sibling following graft rejection of the first BMT. All donors tolerated the procedures well and no relevant side effects occurred. There was no significant difference between the two harvests concerning cell yield and time to engraftment. Our experience shows that for pediatric donors, a second BM donation is safe and feasible and good cellularity can be obtained. We suggest that a second harvest of a pediatric donor can be performed when a strong indication for BMT exists.

The application of evidence-based medicine has enhanced the basis of hemophilia therapy, while resulting in some challenges to patient care. Increasingly, the criteria used for the approval and payment of treatment products by regulatory and reimbursement agencies, respectively, are becoming inflexible and unrealistic. This is occurring particularly in the requirements for demonstrating product efficacy. Concurrently, emerging evidence of the interpatient variability in the clinical response to therapy has led to the proposed personalization of therapeutic regimens. Possible impediments to optimal care include competitive tensions among suppliers who seek to gain label claims for reimbursement purposes, which result in clinical trial designs of, arguably, unethical design, carried out in poor countries. We synthesize these converging developments to suggest some changes to the current hemophilia treatment paradigm, which should make it more patient-centric and enable speedier access to new therapies. Keywords: hemophilia, treatment products, clinical trials, standards, reimbursement

    This study evaluated the safety/tolerability and effectiveness of aripiprazole titrated-dose versus fixed-dose switching strategies from risperidone in patients with schizophrenia experiencing insufficient efficacy and/or safety/tolerability issues. Patients were randomized to an aripiprazole titrated-dose (starting dose 5 mg/day) or fixed-dose (dose 15 mg/day) switching strategy with risperidone down-tapering. Primary endpoint was rate of discontinuation due to adverse events (AEs) during the 12-week study. Secondary endpoints included positive and negative syndrome scale (PANSS), clinical global impressions - improvement of illness scale (CGI-I), preference of medication (POM), subjective well-being under neuroleptics (SWN-K) and GEOPTE (Grupo Español para la Optimización del Tratamiento de la Esquizofrenia) scales. Rates of discontinuations due to AEs were similar between titrated-dose and fixed-dose strategies (3.5% vs. 5.0%; p=0.448). Improvements in mean PANSS total scores were similar between aripiprazole titrated-dose and fixed-dose strategies (-14.8 vs. -17.2; LOCF), as were mean CGI-I scores (2.9 vs. 2.8; p=0.425; LOCF) and SWN-K scores (+8.6 vs.+10.3; OC,+7.8 vs.+9.8; LOCF). Switching can be effectively and safely achieved through a titrated-dose or fixed-dose switching strategy for aripiprazole, with down-titration of risperidone.

    Concordance studies indicate the degree to which instruments measure the same or similar constructs or something different. The aims of this study were to identify the factor structure of the Deamonte Driver Survey and determine the relationship between the Deamonte Driver (a measure of social class stereotyping), the Defining Issues Test 2 (DIT2; a measure of ethical sensitivity), the Color-Blind Racial Attitudes Scale (CoBRAS; a measure of racial stereotyping), and the Knowledge, Efficacy, and Practices Instrument (KEPI; a measure of cultural competence). The results showed a three-factor solution for the Deamonte Driver Survey and significant relationships between CoBRAS and DIT2 subscales and between CoBRAS and Deamonte Driver subscales. Significant relationships between the measures and exploratory variables, underrepresented minority status, age, citizenship, marital status, political stance, English as a first language, and gender were found. The lack of a significant relationship between the KEPI and Deamonte Driver, DIT2, or CoBRAS subscales suggests that the KEPI is measuring a unique construct. These findings showed how these scales contributed to the assessment of cultural competence among dental students and faculty.

    Legal studies usually lag behind economic development.Although company contracting occurs in great number in economic practice,there is no final conclusion on the efficacy of the contracts of company contracting.Views on this issue can be classified into the valid school,the invalid one and circumstantial one.The former two have their benefits and flaws.Only by making distinction between different contracting forms can their respective validity be discussed scientifically.As to the contract issued by the company,it validity should be recognized if only the corporate governance structure is not damaged after the contracting,or vice versa;as to the contract of stock rights issued by share-holders,it should be regarded as invalid as it breaches the principle of limited liability in share-holders established in Company Law.%法学研究往往滞后于经济的发展。尽管经济实践中公司承包早已大量发生,但对于公司承包合同的效力至今尚无定论。目前对此问题的观点可分为有效说、无效说和区别说。有效说和无效说都各有利弊。只有区别公司承包的不同形式,才能科学地分别探讨其合同效力。对于以公司作为发包人的承包合同,只要承包后没有破坏公司的法人治理结构就应承认其合同有效,反之则无效;对于以股东作为发包人的股权承包合同,因其违反了公司法所确立的股东有限责任原则,应当认定合同无效。

Non-invasive brain stimulation, among which transcranial direct current stimulation (tDCS, has opened up new perspectives in addiction treatment. The purpose of this work is to conduct a critical and systematic review of tDCS efficacy, and of technical and methodological considerations in the field of BA.Methods.A bibliographic search has been conducted on the Medline and ScienceDirect databases until December 2014, based on the following selection criteria: clinical studies on tDCS and BA (namely eating disorders, compulsive buying, Internet addiction, pathological gambling, sexual addiction, sports addiction, video games addiction. Study selection, data analysis and reporting were conducted according to the PRISMA guidelines.Results.Out of 402 potential articles, seven studies were selected. So far focusing essentially on abnormal eating, these studies suggest that tDCS (right prefrontal anode / left prefrontal cathode reduces food craving induced by visual stimuli.ConclusionsDespite methodological and technical differences between studies, the results are promising. So far, only few studies of tDCS in BA have been conducted. New research is recommended on the use of tDCS in BA, other than eating disorders.

    Pravafenix(®) is a fixed-dose combination of 40mg of pravastatin and 160 mg of fenofibrate. The rationale behind the use of Pravafenix(®) is based on the increased residual cardiovascular risk observed in high risk patients with hypertriglyceridemia and/or low HDL cholesterol levels despite treatment with statins in monotherapy. In this article, we review the available evidence on the clinical efficacy of Pravafenix(®), which shows complementary benefits in the overall lipid profile of high risk patients with mixed dyslipidemia not controlled with 40-mg pravastatin or 20-mg simvastatin.

    Full Text Available Shein-Chung Chow,1 Fuyu Song2 1Duke University School of Medicine, Durham, NC, USA; 2Peking University Clinical Research Institute, Peking University Health Science Center, Beijing, People's Republic of China Abstract: In clinical development of a test treatment under investigation, clinical trials are often conducted for evaluation of safety and efficacy of the test treatment. To provide an accurate and reliable assessment, adequate and well-controlled clinical trials using valid study designs are necessarily conducted for obtaining substantial evidence of safety and efficacy of the test treatment under investigation. In practice, however, some debatable issues are commonly encountered regardless compliance with good statistics practice and good clinical practice. These issues include, but are not limited to: 1 appropriateness of statistical hypotheses for clinical investigation; 2 correctness of power analysis assumptions; 3 integrity of randomization and blinding; 4 post hoc endpoint selection; 5 impact of protocol amendments on the characteristics of the trial population; 6 multiplicity in clinical trials; 7 missing data imputation; 8 adaptive design methods; and 9 independence of a data monitoring committee. In this article, these issues are briefly described. The impact of these issues on the evaluation of the safety and efficacy of the test treatment under investigation are discussed with examples whenever applicable. Some recommendations regarding possible resolutions of these issues are also provided. Keywords: data safety monitoring committee, endpoint selection, integrity of blinding, missing data imputation, multiplicity, protocol amendment, two-stage adaptive designs

    2016-06-01

    Controlling complex networks has become a forefront research area in network science and engineering. Recent efforts have led to theoretical frameworks of controllability to fully control a network through steering a minimum set of driver nodes. However, in realistic situations not every node is accessible or can be externally driven, raising the fundamental issue of control efficacy: if driving signals are applied to an arbitrary subset of nodes, how many other nodes can be controlled? We develop a framework to determine the control efficacy for undirected networks of arbitrary topology. Mathematically, based on non-singular transformation, we prove a theorem to determine rigorously the control efficacy of the network and to identify the nodes that can be controlled for any given driver nodes. Physically, we develop the picture of diffusion that views the control process as a signal diffused from input signals to the set of controllable nodes. The combination of mathematical theory and physical reasoning allows us not only to determine the control efficacy for model complex networks and a large number of empirical networks, but also to uncover phenomena in network control, e.g., hub nodes in general possess lower control centrality than an average node in undirected networks.

    In their article Mindfulness and discussing ` thorny' issues in the classroom Konstantinos Alexakos et al. (Cult Stud Sci Educ, 2016. doi: 10.1007/s11422-015-9718-0) describe "thorny" issues as "difficult topics to discuss because they are more personal to some perhaps even cause pain and violence." As women from different backgrounds, we engage in a metalogue, which expands on our thoughts and emotions the thorny issues evoked. Our discussion is grounded in theoretical frameworks of mindfulness, wellness, and safe space for learning. We also reflect on our experiences of facing some of the thorny issues in our academic and personal lives. Having trust and respect for one another and being aware of thorny issues allows for a meaningful conversation about the complexity and nuances involved in discussing difficult topics in a classroom setting.

    Full Text Available Reading comprehension has affective and social dimensions as well as its cognitive dimension. Thus, to understand and improve reading instruction, affective and social dimensions should be well understood. Perceived self-efficacy is one of affective issues influencing learning and it should be taken into consideration in reading instruction. With this in mind, this study aims at developing the Reader Self-Efficacy Scale with a group of 518 students as participants. Exploratory and confirmatory factor analyses revealed a 6-item scale with one factor. The Cronbach Alpha coefficient was determined to be 0.948. This new Reader Self-Efficacy Scale could easily be used for training and research purposes depending on its high validity and reliability.

  17. Ethical issues in immunisation.

    Science.gov (United States)

    Isaacs, David; Kilham, Henry; Leask, Julie; Tobin, Bernadette

    2009-01-29

    Discussions about current and future immunisation programmes raise novel questions about familiar ethical issues. Two sets of ethical issues dominate these discussions. The first is the issue of compulsory immunisation: what should be done about parents who fail to immunise their children? The second is: given competing demands on health care budgets, how should principles of justice in access and distribution inform vaccination programmes? This paper considers these two issues in the light of traditional ethical principles. With respect to the first, we argue that compulsion is justified only in cases in which we know with practical certainty that parental failure to immunise puts their own child or other children at high risk of severe illness. We also argue that the state should compensate those who suffer vaccine-related injury. With respect to the second, we claim that allocating resources according to health care need requires establishing priorities between public health programmes such as immunisation and other treatment programmes.

  20. Bioethical issues in the development of biopharmaceuticals

    Directory of Open Access Journals (Sweden)

    Todorović Zoran

    2012-01-01

    Full Text Available Development of biopharmaceuticals is a challenging issue in bioethics. Unlike conventional, small molecular weight drugs, biopharmaceuticals are proteins derived from DNA technology and hybrid techniques with complex three dimensional structures. Immunogenicity of biopharmaceuticals should always be tested in clinical settings due to low predictive value of preclinical animal models. However, non-human primates (NHP and transgenic mice could be used to address certain aspects of immunogenicity. Substantial efforts have been made to reduce NHP use in biopharmaceutical drug development, e.g. study design improvements and changes in regulatory policy. In addition, several expert groups are active in this field (e.g. NC3Rs, BioSafe, and Biopharmaceutical Technical Group. Despite that, there is an increasing trend of use of NHP in preclinical safety testing of biopharmaceuticals, especially regarding monoclonal antibodies. Other potential bioethical issues related biopharmaceutical drug development are their cost/effectiveness ratio, clinical safety assessment, production of biosimilars, and comparison of their efficacy with placebo in countries without intention to market. Identification of the human genome has opened many new bioethical issues. Development of biopharmaceuticals is an important bioethical issue for several reasons. It connects all aspects of contemporary bioethics: bio­medicine (e.g. clinical trials in vulnerable subjects, animal welfare and the most recent ad­vances in biotechnology. In particular, biopharmaceutical drug development is a challenging issue regarding treatment of rare diseases.

The aim of this study is to explore and add additional insight into the nature and scope of ethical issues......: The ideal of being beneficent toward the patient. Here, the ethical issues uncovered in the interviews were embedded in three code-groups: 1) ethical issues related to equality; 2) feeling obligated to do one's best; and 3) transgression of boundaries. Conclusions: In an ethical perspective, physiotherapy...... in private practice is on a trajectory toward increased professionalism. Physiotherapists in private practice have many reflections on ethics and these reflections are primarily based on individual common sense arguments and on deontological understandings.

    New ethical questions have arisen from our ability to intervene in the structure of the genome. Responsible use of this technique requires ethical evaluation in which experts, potential beneficiaries and the general public should all participate. The examples of genetically modified food and of human genetics help to illustrate the issues involved.

    Full Text Available Introduction. The authors analyze contemporary methods of contraception. Regarding oral contraception, they point to agents which decrease the efficacy of oral contraception. They also deal with agents which increase the level of estrogen, thus increasing side effects (paracetamol, vitamin C. Oral contraceptives Oral contraceptives may also have an impact on the efficacy of some medications (anticonvulsants, antidepressants. Health risks of oral contraceptives are also mentioned, as well as WHO's, guidelines for women using contraceptives based on risks and benefits. Other methods of contraception The authors also offer criteria for use of bioactive intrauterine devices (IUD, with recommendations of WHO. Besides men's, there are women's condoms, which are very reliable protection against infections, but their negative side is that they are rather expensive. Bad sides of vaginal wash are also emphasized, although this method is rather widespread in the world. Conclusion. At the end, the authors quote the International Family Planning Fund (IFPF which considers IUD to be the most reliable method of contraception nowadays. .

  7. Efficacy methods to evaluate health communication and marketing campaigns.

    Science.gov (United States)

    Evans, W Douglas; Uhrig, Jennifer; Davis, Kevin; McCormack, Lauren

    2009-06-01

    Communication and marketing are growing areas of health research, but relatively few rigorous efficacy studies have been conducted in these fields. In this article, we review recent health communication and marketing efficacy research, present two case studies that illustrate some of the considerations in making efficacy design choices, and advocate for greater emphasis on rigorous health communication and marketing efficacy research and the development of a research agenda. Much of the outcomes research in health communication and marketing, especially mass media, utilizes effectiveness designs conducted in real time, in the media markets or communities in which messages are delivered. Such evaluations may be impractical or impossible, however, imiting opportunities to advance the state of health communication and marketing research and the knowledge base on effective campaign strategies, messages, and channels. Efficacy and effectiveness studies use similar measures of behavior change. Efficacy studies, however, offer greater opportunities for experimental control, message exposure, and testing of health communication and marketing theory. By examining the literature and two in-depth case studies, we identify advantages and limitations to efficacy studies. We also identify considerations for when to adopt efficacy and effectiveness methods, alone or in combination. Finally, we outline a research agenda to investigate issues of internal and external validity, mode of message presentation, differences between marketing and message strategies, and behavioral outcomes.

    2009-09-01

    This topical issue of Physica Scripta collects selected peer-reviewed contributions based on invited and contributed talks and posters presented at the 15th Central European Workshop on Quantum Optics (CEWQO) which took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu). On behalf of the whole community took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu, cewqo08.phy.bg.ac.yu). On behalf of the whole community of the workshop, we thank the referees for their careful reading and useful suggestions which helped to improve all of the submitted papers. A brief description of CEWQO The Central European Workshop on Quantum Optics is a series of conferences started informally in Budapest in 1992. Sometimes small events transform into important conferences, as in the case of CEWQO. Professor Jozsef Janszky, from the Research Institute of Solid State Physics and Optics, is the founder of this series. Margarita Man'ko obtained the following information from Jozsef Janszky during her visit to Budapest, within the framework of cooperation between the Russian and Hungarian Academies of Sciences in 2005. He organized a small workshop on quantum optics in Budapest in 1992 with John Klauder as a main speaker. Then, bearing in mind that a year before Janszky himself was invited by Vladimir Buzek to give a seminar on the same topic in Bratislava, he decided to assign the name 'Central European Workshop on Quantum Optics', considering the seminar in Bratislava to be the first workshop and the one in Budapest the second. The third formal workshop took place in Bratislava in 1993 organized by Vladimir Buzek, then in 1994 (Budapest, by Jozsef Janszky), 1995 and 1996 (Budmerice, Slovakia, by Vladimir Buzek), 1997 (Prague, by Igor Jex), 1999 (Olomouc, Czech Republic, by Zdenek Hradil), 2000 (Balatonfüred, Hungary, by Jozsef Janszky ), 2001 (Prague, by Igor Jex), 2002 (Szeged, Hungary, by Mihaly Benedict), 2003 (Rostock,Germany, by Werner Vogel and

    The legal status of euthanasia is frequently deliberated. It remains unlawful in Britain and advocates for a change in the law are vigorously opposed by those who argue that it should remain unchanged. An objective account, in which current law and arguments for and against change are exposed, is essential to inform the euthanasia debate. In this article the legal issues concerning euthanasia are examined and arguments raised by proposed changes in the law are considered.

  6. Efficacy paradox and proportional contextual effect (PCE).

    Science.gov (United States)

    Zhang, Weiya; Doherty, Michael

    2017-07-20

    The "efficacy paradox" is when the effect of a treatment tested in an RCT, or evidence-based guideline advice, differs markedly from treatment benefits observed in clinical practice. This arises because in RCT reporting and guideline development treatment efficacy is judged by the separation of the treatment group from the placebo group (the specific treatment effect) whereas in clinical practice it is the overall treatment effect, which includes both specific and contextual responses, that patients experience. This paradox causes a disconnect between guidelines and clinical practice and ignores the importance of contextual response in clinical care. This article fully explains and discusses these issues and presents a possible way to reduce the paradox through an alteration in RCT reporting that shifts the focus to overall treatment benefit and the proportion ("proportional contextual effect") that is explained by placebo and contextual effects.

    The administrative and regulatory issues associated with offshore oil and gas exploration and development in British Columbia were discussed with reference to the creation of a management framework that would ensure that resource development occurs in a socially responsible manner. Provincial governments have jurisdiction over resource management, including intra-provincial trade, commerce and environmental issues within their borders. The federal government has control over resources, subsoil and the seabed out to 200 miles beyond the baseline. The federal government also regulates Frontier Lands, which are divided into Non-Accord and Accord areas. In Accord areas such as Newfoundland and Nova Scotia, oil and gas development is managed by the respective Offshore Petroleum Board. Currently, the British Columbia offshore is a Non-Accord area subject to the administration of Federal legislation. Environmental and regulatory issues were also discussed, along with regional equity, benefits planning, equity versus efficiency, proactivity, and public consultation. It was concluded that there is no scientific, technical or environmental barriers that would prevent the socially responsible development of British Columbia's offshore. There is also much evidence from other jurisdictions that indicates that British Columbia and Canada would benefit from prudent development of offshore oil and gas resources. refs., tabs., figs.

    The main purpose of this review is to provide an overview of the state-of-the-art on research and development issues related to waste combustion with relevance for Swedish conditions. The review focuses on co-combustion in grate and fluidised bed furnaces. It is primarily literature searches in relevant databases of scientific publications with to material published after 1995. As a complement, findings published in different report series, have also been included. Since the area covered by this report is very wide, we do not claim to cover the issues included completely and it has not been possitile to evaluate the referred studies in depth. Basic knowledge about combustion issues is not included since such information can be found elsewhere in the literature. Rather, this review should be viewed as an overview of research and development in the waste-to-energy area and as such we hope that it will inspire scientists and others to further work in relevant areas.

    Full Text Available There has been more interest than I'd ever anticipated in issue 6 "Digital Publication", the first themed issue of Internet Archaeology - so much so that several more related articles have been submitted and will appear in issue 7! The discussion on linearity and hypertext, arising from the contributions by Cornelius Holtorf and Andre Costopoulos, also generated some serious and lengthy debate on our email discussion list intarch-interest for the first time too, and my thanks go out to all who participated - active authorship and readership in practice. Archaeologists are using the web and other electronic media more than ever now, but I believe that this is not just "because it's there". Theoretically and practically, the internet is a valuable tool for us. On the web, rather than on the printed page, we can come closer to fulfilling our concerns about dissemination, we can more easily incorporate many "voices" and facilitate the opening up of our work and our interpretations to critical inquiry, immediately and on a global scale. At the same time, the web also offers new and experimental ways of expressing and communicating our work, and the flexibility of the medium means that our information can even be layered in complexity - depth and the building up of layers and meaning are concepts that every archaeologist is familiar with after all! But there's one more reason why I think archaeology and the web should be embraced. The printed word lies at the very core of a discipline like history; archaeology, on the other hand, is made up of what we see (images, what we feel (experience, what we find (material, what we read (text - it is multimedia. So what better way to communicate all these things than in a like-minded medium?

  15. Ethical issues in nanotechnology.

    Science.gov (United States)

    Florczyk, Stephen J; Saha, Subrata

    2007-01-01

    Nanotechnology is a rapidly developing area in science involved with manipulating matter at the atomic or molecular level. Nanotechnology is typically defined at a scale on the order of less than approximately 100 nm. Matter possesses unique properties at these size levels that are neither Newtonian nor quantum, but between the two regimes.These unique properties have created significant interest and excitement, sparking numerous research investigations. Nanotechnology is a very broad field with many current and potential applications. Some important examples of applications include battlefield activated dynamic armor clothing for soldiers, additives to sunscreens, and diagnostic laboratories on a chip to monitor general personal health. Groundbreaking capabilities often raise new questions. Any new scientific or technological development has the usual concomitant associated ethical issues, specifically regarding containment and regulation. These ethical issues are more pronounced with nanotechnology due to the sharp divide between those who see its great potential and opponents who express fears. Nanotechnology supporters believe that it has the potential to transform our lives dramatically, while opponents of nanotechnology fear that self-replicating "nanobots" could escape from laboratories and reduce all life on earth to "gray goo. "These fears have swayed generally uninformed public opinions via the media and sensational entertainment. A critical discussion of ethical issues surrounding nanotechnology, including the interaction of nanotechnology with the body and the environment--nanobiotechnology--and regulation of nanotechnology, is presented. We advocate strong, uniform regulations for nanotechnology, but only the use of regulations as needed. The limited use of regulations prevents the regulations from becoming burdensome and inhibiting research in the field.

    Science.gov (United States)

    Lorenzi, Nancy M; Riley, Robert T

    2003-03-01

    Information systems fail for a number of reasons. Several failure reasons include communication, complexity, organization, technology, and leadership. Failure can be outlined in four major categories: technical shortcomings, project management shortcomings, organizational issues, and the continuing information explosion. Change management is the process of assisting individuals and organizations in passing from an old way of doing things to a new way of doing things. Change management starts early in a technical process, as the need for making major changes starts at the conceptual level. This paper briefly covers the people side of implementing new information systems, and describes resistance to change and various strategies to manage technological change.

    The arguments of critics and concerns of the public on generating transgenic cloned animals are analyzed for the absence or presence of logical structure. Critics' arguments are symbolically compared with "genetic trespassing," "genetic speeding," or "going the wrong way," and responses are provided to these arguments. Scientists will be empowered to participate in the public discussion and to engage the critics on these issues as they consider thoughtful, plausible responses to their concerns. Temporary moratoriums are recognized as a plausible approach to dealing with possible concerns of new scientific advancements.

  20. Orbital debris issues

    Science.gov (United States)

    Kessler, D. J.

    Orbital debris issues fall into three major topics: Environment Definition, Spacecraft Hazard, and Space Object Management. The major issue under Environment Definition is defining the debris flux for sizes smaller (10 cm in diameter) than those tracked by the North American Aerospace Defense Command (NORAD). Sources for this size debris are fragmentation of larger objects, either by explosion or collision, and solid rocket motor products. Modeling of these sources can predict fluxes in low Earth orbit which are greater than the meteoroid environment. Techniques to measure the environment in the size interval between 1 mm and 10 cm are being developed, including the use of telescopes and radar both on the ground and in space. Some impact sensors designed to detect meteoroids may have detected solid rocket motor products. Once the environment is defined, it can be combined with hypervelocity impact data and damage criteria to evaluate the Spacecraft Hazard. Shielding may be required to obtain an acceptable damage level. Space Object Management includes techniques to control the environment and the desired policy to effectively minimize the hazard to spacecraft. One control technique - reducing the likelihood of future explosions in space - has already been implemented by NASA. The effectiveness of other techniques has yet to be evaluated.

    2012-01-01

    Full Text Available The term “cloud computing” has been in the spotlights of IT specialists the last years because of its potential to transform this industry. The promised benefits have determined companies to invest great sums of money in researching and developing this domain and great steps have been made towards implementing this technology. Managers have traditionally viewed IT as difficult and expensive and the promise of cloud computing leads many to think that IT will now be easy and cheap. The reality is that cloud computing has simplified some technical aspects of building computer systems, but the myriad challenges facing IT environment still remain. Organizations which consider adopting cloud based services must also understand the many major problems of information policy, including issues of privacy, security, reliability, access, and regulation.

    The e8 is a Non-Government Organization of nine power companies from the G8 countries. It was established in 1992 to play an active role in global electricity issues and to promote sustainable energy development. The e8 is governed by the Chairmen of the member companies, who exchange their views on common themes of the year at their annual Summit meetings. At the Evian Summit in May 2006, the Chairmen discussed 'Global Energy Issues' and established a common statement of e8 commitments and recommendations as follows: (1) Optimum mix of energy supply, (2) Investment for infrastructure and demand growth, (3) Promoting sustainable energy development by sharing expertise, (4) Cooperation among electricity companies, (5) Integration and modernisation of transmission networks, (6) Inclusion of large scale-technologies under the Flexible Mechanisms, (7) International financial institutions, (8) Developments of long-term contracts in the electricity sector, (9) International Institutions - Producer and Consumer Countries, (10) Public acceptance. Guided by this statement, e8 will stride ahead toward achieving 3A's (Accessibility, Availability, Acceptability) globally. (auth)

  3. Bituminous sands : tax issues

    Patel, B. [PricewaterhouseCoopers LLP, Calgary, AB (Canada)

    2004-07-01

    This paper examined some of the tax issues associated with the production of bitumen or synthetic crude oil from oil sands. The oil sands deposits in Alberta are gaining more attention as the supplies of conventional oil in Canada decline. The oil sands reserves located in the Athabasca, Cold Lake and Peace River areas contain about 2.5 trillion barrels of highly viscous hydrocarbons called bitumen, of which nearly 315 billion barrels are recoverable with current technology. The extraction method varies for each geographic area, and even within zones and reservoirs. The two most common extraction methods are surface mining and in-situ extraction such as cyclic steam stimulation (CSS); low pressure steam flood; pressure cycle steam drive; steam assisted gravity drainage (SAGD); hot water flooding; and, fire flood. This paper also discussed the following general tax issues: bituminous sands definition; bituminous sands leases and Canadian development expense versus Canadian oil and gas property expense (COGPE); Canadian exploration expense (CEE) for surface mining versus in-situ methods; additional capital cost allowance; and, scientific research and experimental development (SR and ED). 15 refs.

  4. Clinical research: regulatory issues.

    Wermeling, D P

    1999-02-01

    The regulatory issues faced by institutions performing clinical research are described. Many institutions do not have on staff an expert who understands the regulatory issues involved in managing investigational new drug research and who knows the institution's obligations under the federal rules. Because pharmacists understand the FDA regulations that apply to the management of drugs in clinical research, institutions are asking pharmacists to expand their role and manage clinical research offices. Many authorities govern various aspects of investigational drug research. FDA has published regulations for good clinical practice (GCP), and the International Conference on Harmonisation is developing an international standard for the proper management of clinical trials. The guidelines published by the Joint Commission on Accreditation of Healthcare Organizations aim to protect patients who are in the institution to receive health care and also participate in clinical trials. The Social Security Administration Acts specifically state that only items and services that are reasonable and necessary for the diagnosis and treatment of injury or disease can be billed to the government; research-related billings are excluded from coverage. Proper management of drug research is crucial to the success of a research program that is integrated with patient care.

  5. Environmental issues in China

    1991-10-01

    Global concern about the environment is increasing, and the People's Republic of China (PRC) is not immune from such concerns. The Chinese face issues similar to those of many other developing nations. The US Department of Energy is particularly interested in national and world pollution issues, especially those that may infringe on other countries' economic growth and development. The DOE is also interested in any opportunities that might exist for US technical assistance and equipment in combating environmental problems. Our studies of articles in the China Daily, and English-language daily newspaper published by the Chinese government, show that population, pollution, and energy are major concerns of the Chinese Communist Party. Thus this report emphasizes the official Chinese government view. Supporting data were also obtained from other sources. Regardless of the severity of their various environmental problems, the Chinese will only try to remedy those problems with the greatest negative effects on its developing economy. They will be looking for foreign assistance, financial and informational, to help implement solutions. With the Chinese government seeking assistance, the United States has an opportunity to export basic technical information, especially in the areas of pollution control and monitoring, oil exploration methods, oil drilling technology, water and sewage treatment procedures, hazardous waste and nuclear waste handling techniques, and nuclear power plant safety procedures. In those areas the US has expertise and extensive technical experience, and by exporting the technologies the US would benefit both economically and politically. 59 refs., 3 figs.

    Full Text Available Problem statement: Ergonomics so far has had little impact in Malaysia. For most Malaysian managers, ergonomics is not considered to be associated with performance, but rather with occupational health and safety and legislation. Approach: This study reviews the development of ergonomics in Malaysia and the underlying issues related to national development. Results: Many changes need to be made within the ergonomics research, education and practice community by integrating concepts from the social sciences with technological advances into Malaysian culture to enhance productivity and sustainable improvements in the quality of life, while achieving essential health and safety goals. Conclusion/Recommendation: Ergonomics helps to improve performance besides enhancing workplace OSH. It is essential to promote ergonomics concepts and practice to various industries in Malaysia. More effort and skills are required to compensate for the lack of infrastructure in providing a framework within which ergonomics recommendations can be disseminated and realized.

  9. Space radiation protection issues.

    2012-11-01

    The complex charged particle environments in space pose considerable challenges with regard to potential health consequences that can impact mission design and crew selection. The lack of knowledge of the biological effects of different ions in isolation and in combination is a particular concern because the risk uncertainties are very high for both cancer and non-cancer late effects. Reducing the uncertainties is of high priority. Two principal components of space radiation each raise different concerns. Solar particle events (SPE) occur sporadically and are comprised primarily of low- to moderate-energy protons. Galactic cosmic radiation (GCR) is isotropic and relatively invariant in dose rate. GCR is also dominated by protons, but the energy range is wider than in SPE. In addition, the contribution of other light and heavy ions to the health risks from GCR must be addressed. This paper will introduce the principal issues under consideration for space radiation protection.

  10. Methylmercury risk assessment issues

    Lipfert, F.W. [Brookhaven National Lab., Upton, NY (United States); Saroff, L. [USDOE, Washington, DC (United States)

    1996-07-01

    This paper reviews the general background of health risks associated with mercury (Hg), primarily methylmercury (MeHg), with a view towards application to advanced technologies that could reduce any contributions from coal combustion. The need for accurate assessment of such risks is discussed, since Hg is now widely dispersed in the environment and cannot easily be eliminated. The primary pathway of MeHg intake is through eating contaminated fish. The issues of concern include identification of critical health outcomes (various neurological indices) and their confounding factors, accurate assessment of MeHg intake rates, and appropriate use of dose-response functions. Ultimately, such information will be used to evaluate alternative coal combustion systems.

  11. Software Tool Issues

    Hennell, Michael

    This chapter relies on experience with tool development gained over the last thirty years. It shows that there are a large number of techniques that contribute to any successful project, and that formality is always the key: a modern software test tool is based on a firm mathematical foundation. After a brief introduction, Section 2 recalls and extends the terminology of Chapter 1. Section 3 discusses the the design of different sorts of static and dynamic analysis tools. Nine important issues to be taken into consideration when evaluating such tools are presented in Section 4. Section 5 investigates the interplay between testing and proof. In Section 6, we call for developers to take their own medicine and verify their tools. Finally, we conclude in Section 7 with a summary of our main messages, emphasising the important role of testing.

  12. Issues in energy finance

    Science.gov (United States)

    Khokher, Zeigham Islam

    As opposed to the well developed and understood equity markets, the energy markets are still in their infancy. The explosion of contracts, of both the primary and derivative types, are testament both to the existing size and the untapped growth potential of this exciting industry. However, because of its relative youth many basic issues in the energy markets remain unresolved. This thesis introduces some interesting questions and provides insights into these issues. Thematically, the chapters of this thesis are linked by an emphasis on valuation and risk management decisions. A contribution of this thesis is to show that subtle differences between the endogenous price process in our general equilibrium setting and the exogenous processes considered in earlier papers can generate significant differences in both financial and real option values. In addition to these valuation concerns there has been much debate about the corporate risk management function. Finance theory suggests that a value maximizing corporation should either be indifferent to hedging or, in the presence of certain imperfections, it should completely hedge all exposures. Both these extremes contradict empirical evidence. We show that existing corporate hedging behaviour is best explained in light of both physical market imperfections and directional predictions on future prices. While these speculative motives may arise from corporate hubris or genuine informational advantages, we argue that it would be difficult to implement private information in the absence of noise traders. Related to the risk management decision is the existence of futures risk premia. These premia have been thought to be cause by covariance with priced factors or due to the hedging demands of consumers and producers. This thesis argues that inventories serve as a signal of available quantity, which coupled with consumers fears regarding stockouts can induce a positive relationship between premia and inventories.

    2007-01-01

    Full Text Available The present review examines four current issues related to the efficacy, patient tolerance and safety of the following bowel cleansing agents: oral sodium phosphate (NaP, polyethylene glycol (PEG and magnesium citrate (Pico-Salax, Ferring Pharmaceuticals Inc, Canada, an agent recently made available in Canada. MedLine and PubMed databases were systematically searched to identify studies related to the efficacy of altered PEG solutions combined with adjunct treatments; the efficacy, tolerability and safety of Pico-Salax; the association between nephrocalcinosis, and chronic renal failure and oral NaP use; and the role of diet. Although lower volume PEG solutions combined with adjuvant agents were generally associated with better patient tolerance, their efficacy was varied and interpretation of this end point is complicated by study design issues. There are very few reported studies of Pico-Salax, and as a result, there are insufficient data to draw conclusions about the efficacy of this agent. The available data suggest that Pico-Salax may be better tolerated by patients, than oral NaP and PEG solutions. There is a paucity of hemodynamic monitoring data pre- and postadministration, but the available data suggests that this small-volume osmotic agent could cause subclinical contraction of the intravascular space. Recent case reports suggest an association between nephrocalcinosis and oral NaP ingestion, but to date, these reports have been confined to a single centre. Preliminary studies suggest that this is not a widespread problem, but more studies are needed. There are only a few studies examining diet and patient tolerability, but they do suggest that diet may be liberalized with some cleansing regimens to enhance tolerability without decreasing efficacy. The present review highlights current controversies and advances in colon cleansing before colonoscopy, and also identifies areas for further study.

    1998-01-01

    Occupational therapists are expanding their use of custom and commercial soft splints fabricated from neoprene (polychloroprene), but little has been written regarding dermatological issues associated with this material. Skin contact with neoprene poses two dermatological risks: allergic contact dermatitis (ACD) and miliaria rubra (i.e., prickly heat). Allergic reaction to neoprene is generally ascribed to the accelerants used to manufacture the man-made rubber, specifically thiourea compounds and mercaptobenzothiazole (MBT). Symptoms of neoprene-related ACD include itching, skin eruptions, swelling, and hemorrhages into the skin. Miliaria rubra creates small, red, elevated, inflammatory papules and a tingling, burning sensation. Although neoprene hypersensitivity is rare, its incidence may grow as neoprene becomes a more commonly used material. It is recommended that therapists screen patients for a history of dermatological reactions to neoprene or other materials containing thiourea compounds or MBT and educate patients to discontinue splint use if dermatological symptoms develop. Therapists are also encouraged to notify splint manufacturers regarding all ACD reactions.

    Systemic sclerosis is a systemic, inflammatory, autoimmune disease affecting the skin and viscera, manifesting pathologically with microvascular lesions, perivascular infiltration by mononuclear cells and increased deposition of extracellular collagen. The rarity of the disease as well as its propensity to appear in the early 1940s, explain the low frequency of concurrent scleroderma and pregnancy. However, the marked female excess, as well as the trend for increasing maternal age due to social change and assisted reproductive technologies, renders heightened significance to issues of fertility, pregnancy course and pregnancy outcomes. In the past, scleroderma patients were thought to be at high risk for poor fetal and maternal outcome, but more current retrospective studies show that despite an increased frequency of prematurity and small for gestational age infants, overall maternal and neonatal survival is good. Hence, at present, with close monitoring and appropriate therapy most scleroderma patients can sustain a successful pregnancy. Therapy with hydroxychloroquine and low dose steroids as well as judicious use of intravenous immunoglobulins is permitted. Renal crisis remains the most dreaded complication of a scleroderma pregnancy and necessitates prompt institution of ACE inhibitor therapy despite its potential teratogenicity. In order minimize the risk for renal crisis, pregnancies should be avoided in rapidly progressive diffuse disease as such patients are at a greater risk for developing serious cardiopulmonary and renal problems early in the disease. This review shall focus on the bi-directional effects of scleroderma on fertility and pregnancy as well as on the management of pregnancy and delivery in the scleroderma patient.

  4. Special Issue: Tsallis Entropy

    Directory of Open Access Journals (Sweden)

    2012-02-01

    Full Text Available One of the crucial properties of the Boltzmann-Gibbs entropy in the context of classical thermodynamics is extensivity, namely proportionality with the number of elements of the system. The Boltzmann-Gibbs entropy satisfies this prescription if the subsystems are statistically (quasi- independent, or typically if the correlations within the system are essentially local. In such cases the energy of the system is typically extensive and the entropy is additive. In general, however, the situation is not of this type and correlations may be far from negligible at all scales. Tsallis in 1988 introduced an entropic expression characterized by an index q which leads to a non-extensive statistics. Tsallis entropy, Sq, is the basis of the so called non-extensive statistical mechanics, which generalizes the Boltzmann-Gibbs theory. Tsallis statistics have found applications in a wide range of phenomena in diverse disciplines such as physics, chemistry, biology, medicine, economics, geophysics, etc. The focus of this special issue of Entropy was to solicit contributions that apply Tsallis entropy in various scientific fields.

    Full Text Available In this paper the author reflects the questions of humans’ relationship to the environment and of their ecological behaviour that becomes together with the development of modern technologies increasingly relevant just as the question whether humans are able to affect fundamentally the environment on the Earth by their activities. According to some authors (e.g. Ehrlich, 1968; Gore, 2006; Wilson, 1995; Winter, Koger, 2009; Šmajs, 2005 human survival is directly connected with people’s relationship to the nature; but other influential authors have contradictory opinions or they are at least afraid of overestimation of ecological activities that can lead to neglecting of other important problems (e.g. Simon, 1981; Goklany, 2007; Lomborg, 2007; Klaus, 2007, 2009.These issues are dealt in this article mainly from the perspective of psychological theories and concepts – the Freud’s concept of unconsciousness is discussed as well as groupthink, theory of dissonance, contingency trap, Milgram’s theory of autonomous and agentic state of consciousness, group and intergroup behaviour, social dilemma – tragedy of the commons. Achieving a sustainable way of life depends on the equilibrium between consumption of individuals and regenerative abilities of the natural environment. However, people still behave as if they were separated from the nature.

    Wang, Liqiu; Fan, Jing

    2010-05-22

    Nanofluids are a new class of fluids engineered by dispersing nanometer-size structures (particles, fibers, tubes, droplets) in base fluids. The very essence of nanofluids research and development is to enhance fluid macroscopic and megascale properties such as thermal conductivity through manipulating microscopic physics (structures, properties and activities). Therefore, the success of nanofluid technology depends very much on how well we can address issues like effective means of microscale manipulation, interplays among physics at different scales and optimization of microscale physics for the optimal megascale properties. In this work, we take heat-conduction nanofluids as examples to review methodologies available to effectively tackle these key but difficult problems and identify the future research needs as well. The reviewed techniques include nanofluids synthesis through liquid-phase chemical reactions in continuous-flow microfluidic microreactors, scaling-up by the volume averaging and constructal design with the constructal theory. The identified areas of future research contain microfluidic nanofluids, thermal waves and constructal nanofluids.

    Composing the Curriculum For your summer reading pleasure this month's issue provides a wide range of subjects and activities. Our lead article is a tribute to a chemist-composer, Lejaren A. Hiller, Jr., as well as an examination of the interesting relationship between chemistry (and science) and music. Like Hiller, Wamser and Wamser (page 601) love both chemistry and music, and this comes through loud and clear in their historical perspective on Hiller's work. Much of the rest of the issue impinges on the chemistry curriculum in one form or another. Rettich, Bailey, Frank, and Frick (page 638) describe an integrated first- and second-year curriculum being developed at Illinois Wesleyan University that includes all subdisciplines of chemistry. They describe ways to teach topics such as acids and bases so that the perspectives of (for example) organic and inorganic chemistry are integrated and contemporaneous. Those contemplating a popular reform, group work or cooperative learning, will be interested in Birk and Kurtz's program (page 615) for training teaching assistants using cooperative learning. Surely TAs who have participated in cooperative groups to develop their own techniques for handling discussion and lab sessions will be able to use group learning to better advantage. Several years ago the ACS Division of Chemical Education set up a Task Force on the General Chemistry Curriculum. With support from the National Science Foundation and others, the task force has been quite active. In addition to the summative reports published here (pages 617-636) on four areas in which general chemistry teaching can be improved, they have contributed many Forum columns in earlier issues of the Journal and have published much of their work in New Directions for General Chemistry: A Resource for Curricular Change; Baird W.

  11. Radioactive waste storage issues

    Energy Technology Data Exchange (ETDEWEB)

    1994-08-15

    In the United States we generate greater than 500 million tons of toxic waste per year which pose a threat to human health and the environment. Some of the most toxic of these wastes are those that are radioactively contaminated. This thesis explores the need for permanent disposal facilities to isolate radioactive waste materials that are being stored temporarily, and therefore potentially unsafely, at generating facilities. Because of current controversies involving the interstate transfer of toxic waste, more states are restricting the flow of wastes into - their borders with the resultant outcome of requiring the management (storage and disposal) of wastes generated solely within a state`s boundary to remain there. The purpose of this project is to study nuclear waste storage issues and public perceptions of this important matter. Temporary storage at generating facilities is a cause for safety concerns and underscores, the need for the opening of permanent disposal sites. Political controversies and public concern are forcing states to look within their own borders to find solutions to this difficult problem. Permanent disposal or retrievable storage for radioactive waste may become a necessity in the near future in Colorado. Suitable areas that could support - a nuclear storage/disposal site need to be explored to make certain the health, safety and environment of our citizens now, and that of future generations, will be protected.

The authors developed a methodology, based on hazards assessment, to identify and risk rank over 5000 safety issues collected at INEEL. This approach required that it was easily applied and understandable for site adaptation and commensurate with the Integrated Safety Plan. High-risk issues were investigated and mitigative/preventive measures were suggested and ranked based on a cost-benefit scheme to provide risk-informed safety measures. This methodology was consistent with other integrated safety management goals and tasks providing a site-wide risk informed decision tool to reduce hazardous conditions and focus resources on high-risk safety issues. As part of the issue management plan, this methodology was incorporated at the issue collection level and training was provided to management to better familiarize decision-makers with concepts of safety and risk. This prioritization methodology and issue dissemination procedure will be discussed. Results of issue prioritization and training efforts will be summarized. Difficulties and advantages of the process will be reported. Development and incorporation of this process into INEELs lessons learned reporting and the site-wide integrated safety management program will be shown with an emphasis on establishing self reliance and ownership of safety issues.

    2002-01-01

    Planetary exploration by astronauts will require extended periods of habitation on a planet's surface, under the influence of environmental factors that are different from those of Earth and the spacecraft that delivered the crew to the planet. Human exploration of Mars, a possible near-term planetary objective, can be considered a challenging scenario. Mission scenarios currently under consideration call for surface habitation periods of from 1 to 18 months on even the earliest expeditions. Methods: Environmental issues associated with Mars exploration have been investigated by NASA and the National Space Biomedical Research Institute (NSBRI) as part of the Bioastronautics Critical Path Roadmap Project (see http ://criticalpath.jsc.nasa.gov). Results: Arrival on Mars will immediately expose the crew to gravity only 38% of that at Earth's surface in possibly the first prolonged exposure to gravity other than the 1G of Earth's surface and the zero G of weightless space flight, with yet unknown effects on crew physiology. The radiation at Mars' surface is not well documented, although the planet's bulk and even its thin atmosphere may moderate the influx of galactic cosmic radiation and energetic protons from solar flares. Secondary radiation from activated components of the soil must also be considered. Ultrafine and larger respirable and nonrespirable particles in Martian dust introduced into the habitat after surface excursions may induce pulmonary inflammation exacerbated by the additive reactive and oxidizing nature of the dust. Stringent decontamination cannot eliminate mechanical and corrosive effects of the dust on pressure suits and exposed machinery. The biohazard potential of putative indigenous Martian microorganisms may be assessed by comparison with analog environments on Earth. Even in their absence, human microorganisms, if not properly controlled, can be a threat to the crew's health. Conclusions: Mars' surface offers a substantial challenge to the

    Communication about remote sensing data quality between data providers and users as well as between the users is often difficult. The users have a hard time figuring out if a product has known problems over their region of interest and data providers have to spend a lot of effort to make this information available, if it exists. Scientific publications are one tool for communicating with the users base but they are static and mostly one way. As a data provider it is also often difficult to make feedback, received from users, available to the complete user base. The Geo Issue Tracking System (GeoITS) is an Open Source Web Application which has been developed to mitigate these problems. GeoITS combines a mapping interface (Google Maps) with a simple wiki platform. It allows users to give region specific feedback on a remote sensing product by drawing a polygon on the map and describing the problems they had using the remote sensing product in this area. These geolocated wiki entries are then viewable by other users as well as the data providers which can modify and extend the entries. In this way the conversations between the users and the data provider are no longer hidden in e.g. emails but open for all users of the dataset. This new kind of communication platform can enable better cooperation between users and data providers. It will also provide data providers with the ability to track problems their dataset might have in certain areas and resolve them with new product releases. The source code is available via http://github.com/TUW-GEO/geoits_dev A running instance can be tried at https://geoits.herokuapp.com/

    Advanced Instrumentation in the Educational Laboratory The instruments that chemists use in their research have changed dramatically in the past decades. The explosion in new techniques and their instrumental counterparts has been made possible by two significant advances. The rapid propagation of computer chips and circuitry provides opportunities to collect more specialized and refined data than ever before. Computer-controlled instruments can detect events that a human researcher would never perceive and can record hundreds of data points in the time that a person could only observe one or two. Coupled with these advances in technology are advances in theory that allow more sophisticated interpretation of data. A hundred years ago a sophisticated instrument was a balance that could weigh minute quantities. Today a sophisticated instrument is one that can identify the composition of that minute sample, determine its molecular weight, or reveal a great deal about its energy states and bonding. This bonanza of new instruments is wonderful for the research chemist but a curricular headache for the chemistry teacher. It takes more time to learn how to run an NMR than to use a balance, and more sophistication on the part of the student is needed to interpret the data. And yet many courses that only a generation ago sported an expensive analytical balance as its prize instrument now require students to understand and operate a whole panoply of complex tools. Teachers faced with accommodating these curricular changes will find several articles in this issue helpful--either providing information on new techniques or descriptions of how to incorporate them into the classroom. Electrospray ionization mass spectrometry is one of the newest tools that has been added to the analytical arsenal. It is an extension of mass spectrometry that overcomes the old barrier that allowed only analysis of low molecular weight, volatile compounds. It is now possible to use MS for

    There is an active discussion in the public health community on how to assess and incorporate, in addition to safety and measures of protective efficacy, the full public health value of preventive vaccines into the evidence-based decision-making process of vaccine licensure and recommendations for public health use. The conference "Beyond efficacy: the full public health impact of vaccines in addition to efficacy measures in trials" held in Annecy, France (June 22-24, 2015) has addressed this issue and provided recommendations on how to better capture the whole public health impact of vaccines. Using key examples, the expert group stressed that we are in the midst of a new paradigm in vaccine evaluation, where all aspects of public health value of vaccines beyond efficacy should be evaluated. To yield a wider scope of vaccine benefits, additional measures such as vaccine preventable disease incidence, overall efficacy and other outcomes such as under-five mortality or non-etiologically confirmed clinical syndromes should be assessed in addition to traditional efficacy or effectiveness measurements. Dynamic modelling and the use of probe studies should also be considered to provide additional insight to the full public health value of a vaccine. The use of burden reduction and conditional licensure of vaccines based on collection of outcome results should be considered by regulatory agencies.

  18. Ethical issues in neuroprosthetics

    Science.gov (United States)

    Glannon, Walter

    2016-04-01

    Objective. Neuroprosthetics are artificial devices or systems designed to generate, restore or modulate a range of neurally mediated functions. These include sensorimotor, visual, auditory, cognitive affective and volitional functions that have been impaired or lost from congenital anomalies, traumatic brain injury, infection, amputation or neurodevelopmental and neurodegenerative disorders. Cochlear implants, visual prosthetics, deep brain stimulation, brain-computer interfaces, brain-to-brain interfaces and hippocampal prosthetics can bypass, replace or compensate for dysfunctional neural circuits, brain injury and limb loss. They can enable people with these conditions to gain or regain varying degrees of control of thought and behavior. These direct and indirect interventions in the brain raise general ethical questions about weighing the potential benefit of altering neural circuits against the potential harm from neurophysiological and psychological sequelae. Other ethical questions are more specific to the therapeutic goals of particular neuroprosthetics and the conditions for which they are indicated. These include informed consent, agency, autonomy (free will) and identity. Approach. This review is an analysis and discussion of these questions. It also includes consideration of social justice issues such as how to establish and implement fair selection criteria in providing access to neuroprosthetic research and balancing technological innovation with patients’ best interests. Main results. Neuroprosthetics can restore or improve motor and mental functions in bypassing areas of injury or modulating dysregulation in neural circuits. As enabling devices that integrate with these circuits, neuroprosthetics can restore varying degrees of autonomous agency for people affected by neurological and psychiatric disorders. They can also re-establish the connectedness and continuity of the psychological properties they had before injury or disease onset and thereby

    Hydrogen is often proposed as the fuel of the future, but the transformation from the present fossil fuel economy to a hydrogen economy will need the solution of numerous complex scientific and technological issues, which will require several decades to be accomplished. Hydrogen is not an alternative fuel, but an energy carrier that has to be produced by using energy, starting from hydrogen-rich compounds. Production from gasoline or natural gas does not offer any advantage over the direct use of such fuels. Production from coal by gasification techniques with capture and sequestration of CO₂ could be an interim solution. Water splitting by artificial photosynthesis, photobiological methods based on algae, and high temperatures obtained by nuclear or concentrated solar power plants are promising approaches, but still far from practical applications. In the next decades, the development of the hydrogen economy will most likely rely on water electrolysis by using enormous amounts of electric power, which in its turn has to be generated. Producing electricity by burning fossil fuels, of course, cannot be a rational solution. Hydroelectric power can give but a very modest contribution. Therefore, it will be necessary to generate large amounts of electric power by nuclear energy of by renewable energies. A hydrogen economy based on nuclear electricity would imply the construction of thousands of fission reactors, thereby magnifying all the problems related to the use of nuclear energy (e.g., safe disposal of radioactive waste, nuclear proliferation, plant decommissioning, uranium shortage). In principle, wind, photovoltaic, and concentrated solar power have the potential to produce enormous amounts of electric power, but, except for wind, such technologies are too underdeveloped and expensive to tackle such a big task in a short period of time. A full development of a hydrogen economy needs also improvement in hydrogen storage, transportation and distribution

    Organic Chemistry--New Challenges Perhaps more than any other of the chemical subdisciplines, the scope and focus of organic chemistry has been changed by modern technology and theoretical advances, and these changes have had an equally striking effect on the undergraduate curriculum. The main challenge in organic chemistry classes has shifted, in less than a generation, from memorizing all the groups, naming conventions, and classes of reactions to understanding complex interactions at the structural and electronic orbital level. As biochemistry and polymer chemistry have grown from being the purview of a few specialists to full-blown disciplines of their own, they have also migrated from interesting, but optional, chapters at the back of the book to separate courses in the curriculum. The availability of inexpensive instrumentation means undergraduates routinely use NMR and mass spec instead of melting points to identify their products. And the changes are continuing: segments of biochemistry are metamorphizing into molecular biology and polymer chemistry is finding interconnections with materials science. In fact, as our understanding of chemical reactions at molecular and electronic levels expands, it becomes more and more difficult to decide on demarcations between the subdisciplines. Organic chemistry is an organizational construct that once was useful for segregating certain topics into a coherent two-semester introductory course. Today, it covers so much territory that no one who is an "organic chemist" can know even a small fraction of the territory and faces unique challenges when designing and teaching undergraduate courses. In a wide spectrum of articles in this issue that fall under the "organic" umbrella--from environmental chemistry to new polymer products--teachers share their specific experiences and creative solutions to these challenges, providing their colleagues with new ideas, processes, and pedagogic approaches. To start off, we can examine

  2. Efficacy of antihypertensive drugs.

    Dixon, G T; Johnson, E S

    The magnitude of the fall in blood-pressure in response to an antihypertensive drug depends on the level of the pretreatment pressure, and there is a direct relationship between the two in that the higher the pretreatment pressure the greater the fall in pressure in response to treatment. This simple relationship is inherent in the practical situation of titrating the diastolic blood-pressures of a group of hypertensive patients to a predetermined level. It is assumed that notionally the dose of an antihypertensive drug can be increased in all patients until the diastolic pressure is reduced to the predetermined level. When the fall in diastolic pressure (deltaD.P.) is plotted against pretreatment diastolic pressure (P.T.D.P.), the points for all patients lie on a straight line of slope unity and negative deltaD.P.-intercept numerically equal to the predetermined diastolic-pressure level. This straight-line relationship is termed the predetermined ideal response line. Analysis of data from clinical trials shows that, despite the variability inherent in the practical situation, the data appear to conform to this straight-line relationship. The method of assessing the efficacy of antihypertensive agents is essentially a comparison of each experimental point with the theoretical predetermined response line. In its simplest form the method consists in constructing a scatter diagram of deltaD.P. against P.T.D.P. for all patients. Patients can then be classified as responders or non-responders according to their position on the diagram relative to the predetermined response line. This method of assessing the efficacy of antihypertensive agents has several advantages, the most important of which is that it provides a simple method for displaying all the relevant information in a readily comparable form.

    Full Text Available The concept of occupational self-efficacy means the efficacy perceptions of employees in their occupational fields, and the concept of organizational silence means the employees avoid to voice their ideas and suggestions about organizational issues. The main aim of this study is to examine the relationship between the concepts of occupational self-efficacy and organizational silence by revealing employees’ perceptions of occupational self-efficacy and organizational silence level. With this aim, the survey study was conducted on total 114 academicians who work in University of Bayburt. As a result of research, while the significant relationship was found between employees’ perceptions of occupational self-efficacy and organizational silence level, there was reached a result that this relationship incurred the negatively relationship between perceptions of occupational self-efficacy and negative silence.

    Computational Chemistry for the Masses Not long ago, chemical computation was considered a specialty area requiring extensive computer knowledge, power, and time. Over the past decade, however, it has changed from the arcane pursuit of a few advanced university researchers in the area of physical chemistry to a familiar tool used by a wide range of chemists. Nevertheless, it has required its practitioners to have extensive knowledge of computer programming and a thorough understanding of theoretical chemical concepts and as a result usually was reserved for the graduate curriculum. Now a further metamorphosis is in progress, as computational chemistry moves into the undergraduate curriculum, often using off-the-shelf software--commercial packages or adaptations of them that are readily shared by their creators. As we put this issue together, we realized that many of the articles involved sophisticated computations that would not have been possible a few years ago in the courses described. Further, the hard and software used was widely available at a reasonable cost. Some of the articles focus on the teaching of computational methods and others simply incorporate it as a facet in their overall strategy; however, taken together, they reflect a strong trend to utilize a diverse set of readily available methods and products in the undergraduate curriculum. The most familiar recent use of computational chemistry is the computer design of molecules in organic, medicinal, and biochemistry. However, computational chemistry is useful for inorganic chemists as well and is now migrating to undergraduate courses. Lipkowitz, Pearl, Robertson, and Schultz (page 105) make a strong case for its inclusion and present a two-week component they have developed for their senior-level laboratory course. Comba and Zimmer (page 108) offer a review of inorganic molecular mechanics calculations, which is designed for the novice and includes the basic equations, their application to

    These colloquium proceedings will be valuable, the blurb says, for graduate students and researchers in cosmology and theoretical astrophysics. Specifically, the book 'looks at both the strengths and weaknesses of the current big bang model in explaining certain puzzling data' and gives a 'comprehensive coverage of the expanding field of cosmology'. The reality is rather different. Conference proceedings rarely compare in value with a solid monograph or good review articles, and Current Issues in Cosmology is no exception. The colloquium was convened by the two editors, who have both long harboured doubts about the big bang, and was held in Paris in June 2004. The proceedings contain 19 presented papers and relatively brief summary comments by four panel speakers. The questions and answers at the end of each talk and a general discussion at the end were recorded and transcribed but contain little of interest. The nature of the colloquium is indicated by panellist Francesco Bertola's comment: 'While in the 1950s it was possible to speak of rival theories in cosmology, now the big-bang picture has no strong rivals. This is confirmed by the fact that out of 1500 members of the IAU Division VIII (Galaxies and the Universe) only a dozen, although bright people, devote their time to the heterodox views.' This was largely a platform for them to give their views. At least half of the dozen, all the 'usual suspects', were present: Geoffery and Margaret Burbidge, Jayant Narlikar, Halton Arp, Chandra Wickramasinghe and, in spirit only but playing a role somewhat like the ghost of Hamlet's father, the late Fred Hoyle. Doubters presented 12 of the 19 papers. Orthodoxy should certainly be challenged and the sociology of science questioned, but I found two main problems with this book. The papers putting the orthodox view are too short, even perfunctory. The most that a serious graduate student would get out of them is a reference

  17. Place-based education: An impetus for teacher efficacy

    Science.gov (United States)

    Coleman, Tamara Chase

    This research investigated professional development in place-based (PB) methodology on the efficacy of science teachers. While teachers are expected to use best practices they do not always implement them due to a lack of efficacy in implementation. A professional development program (PD) was designed to increase confidence among teachers planning to incorporate PB methods. Place-based education (PBE) is recognized as a best-practice among professional educators. PBE includes the selection, design and engagement with science using the geographic place as the content. The literature reports that student learning and teacher efficacy will improve when teachers are prepared effectively in PB practices. This dissertation research examined the effects of PD in PB methodology and its influence on the efficacy of seven science teachers who participated in this research. An exploratory, qualitative research approach was used to study the characteristics of change among teachers. Qualitative information was collected about the teachers' confidence with PBE methodology and practices through interviews, in reflective journals and through observations of them working with students in PB settings. Changes in teacher efficacy were accompanied by their becoming more intentional with PBE, networking with experts and expressing a commitment to connect content with the community. The consistency of changes in efficacy among the seven teachers in the study was mixed. Three of the teachers became more confident in their approach to teaching using PB methods and reported the gain in confidence was influenced by the PBE professional development. Three teachers reported that the PD had little effect on their efficacy as teachers to implement PBE. These teachers cited complications from more critical issues in their careers such as time to prepare PBE lessons and meaningful participation in the PD. Those difficulties proved to be hindrances in developing efficacy in implementing PBE

  18. Reticence, Accuracy and Efficacy

    Science.gov (United States)

    Oreskes, N.; Lewandowsky, S.

    2015-12-01

    James Hansen has cautioned the scientific community against "reticence," by which he means a reluctance to speak in public about the threat of climate change. This may contribute to social inaction, with the result that society fails to respond appropriately to threats that are well understood scientifically. Against this, others have warned against the dangers of "crying wolf," suggesting that reticence protects scientific credibility. We argue that both these positions are missing an important point: that reticence is not only a matter of style but also of substance. In previous work, Bysse et al. (2013) showed that scientific projections of key indicators of climate change have been skewed towards the low end of actual events, suggesting a bias in scientific work. More recently, we have shown that scientific efforts to be responsive to contrarian challenges have led scientists to adopt the terminology of a "pause" or "hiatus" in climate warming, despite the lack of evidence to support such a conclusion (Lewandowsky et al., 2015a. 2015b). In the former case, scientific conservatism has led to under-estimation of climate related changes. In the latter case, the use of misleading terminology has perpetuated scientific misunderstanding and hindered effective communication. Scientific communication should embody two equally important goals: 1) accuracy in communicating scientific information and 2) efficacy in expressing what that information means. Scientists should strive to be neither conservative nor adventurous but to be accurate, and to communicate that accurate information effectively.

  19. IMAP statement on contraceptive efficacy.

    Science.gov (United States)

    1994-08-01

    Unwanted pregnancy may have serious negative effects upon the health and well-being of individuals and families. The use of effective contraception is therefore important. Efficacy, however, is not the only factor considered by clients when choosing a contraceptive method, so counsellors and service providers should not promote methods on the sole basis of their efficacy, irrespective of client preference. With regard to method efficacy, important considerations which may affect the choice of a method are the availability of emergency contraception and access to safe abortion services in the event of method failure. Biological factors such as age, parity, and whether a woman is breast feeding may affect contraceptive efficacy and should be a consideration when choosing a method. Contraceptive efficacy is usually measured in terms of failure rates calculated from the number of pregnancies which occur during a specified period of contraceptive use. Method failure is that attributable to the method, while user failure is that attributable to incorrect use of the method in addition to method failure. The failure rates for specific methods of contraception reported in the literature vary, sometimes substantially. The article briefly considers the measurement of efficacy and human factors affecting contraceptive efficacy with regard to clients, providers, and managers.

    Assessment of the efficacy of anthelminthic treatment in public health is a broad concept, which goes beyond parasitological methods and should be clearly defined according to several indicators of morbidity. Several factors may influence the efficacy of anthelminthic drugs. The quality of drug is an issue of great importance, especially when produced locally as a generic product and used in large-scale chemotherapy-based control programmes. Other factors include the drug-patient interaction, the host-parasite relationship, the diagnostic method used, genetic variations between parasite strains and induced drug resistance. Veterinary scientists have warned that drug resistance can be selected through frequent mass treatment of sheep and goats and have developed a body of knowledge on evaluation of efficacy and detection of resistance in nematodes of veterinary importance. In soil-transmitted nematodes infections of humans, the egg reduction rate (ERR), the egg hatch assay (EHA) and novel molecular biological techniques may be used to monitor drug efficacy in helminth control programmes and to detect early occurrence of resistance. Evidence of reduced drug efficacy of some anthelminthics has been suggested by recent studies and strategies to prevent or delay the emergence of drug resistance in human soil-transmitted nematodes.

    Relations to discuss how professionals and organizations battle over issue control through the designation of tasks and the creation of overlapping networks. We outline the emergence of ‘issue professionals’ and how they attempt network management. We do so via a case on transnational sustainability......Professionals and organizations both seek to exploit and cooperate with each other. Professionals seek alliances in their own peer networks while organizations do the same. These networks carry not only information that inform incentives but norms about appropriate forms of governance and practices...... that guide how they actually work. In this paper we outline how professionals and organizations operate in two-level networks through a focus on issue control over issues of transnational governance. As such, this interdisciplinary paper brings together insights from Organization Studies and International...

    @@ Yang : Hello, everybody ! Recently, the discussion on constructing the security cooperative mechanism of Northeast Asia has been increasing both at home and abroad, which has almost t become another hot topic next to the Korean nuclear issue. Why is there such a phenomenon? Judging from the perspective of the regional situation, there have appeared two respects of "changing" and "unchanging" factors in the past few years. Should we consider that the "unchanging factors"have led to the breakout of the Korean Peninsula nuclear crisis again,and the "changing factors" have caused new changes in the regional circumstance following the crisis and the ways of resolving the issue; and with the Korean nuclear issue as a turning point, have these "changing" and "unchanging" factors led to warming-up of the issue of the regional security mechanism in both positive and negative ways?

  16. Obesity and hormonal contraceptive efficacy.

    Robinson, Jennifer A; Burke, Anne E

    2013-09-01

    Obesity is a major public health concern affecting an increasing proportion of reproductive-aged women. Avoiding unintended pregnancy is of major importance, given the increased risks associated with pregnancy, but obesity may affect the efficacy of hormonal contraceptives by altering how these drugs are absorbed, distributed, metabolized or eliminated. Limited data suggest that long-acting, reversible contraceptives maintain excellent efficacy in obese women. Some studies demonstrating altered pharmacokinetic parameters and increased failure rates with combined oral contraceptives, the contraceptive patch and emergency contraceptive pills suggest decreased efficacy of these methods. It is unclear whether bariatric surgery affects hormonal contraceptive efficacy. Obese women should be offered the full range of contraceptive options, with counseling that balances the risks and benefits of each method, including the risk of unintended pregnancy.

  17. Ethical issues in Alzheimer's disease: an overview.

    Science.gov (United States)

    Leuzy, Antoine; Gauthier, Serge

    2012-05-01

    Alzheimer's disease (AD) accounts for the majority of dementia cases and leaves clinicians, patients, family members, caregivers, and researchers faced with numerous ethical issues that vary and evolve as a function of disease stage and severity. While the disclosure of a diagnosis of AD dementia is difficult enough, advances in the neurobiology of AD--embodied in the recent revisions to the AD diagnostic guidelines--have translated into an increasing shift toward the diagnosis being made in its pre-dementia stages, when patients have full insight into their prognosis. Genetic issues in AD are significant in the case of rare families with an early onset (before age 65) form of the disease, owing to the presence of deterministic mutations. While genetic testing for the apolipoprotein E (APOE) gene--a risk factor for sporadic AD--is widely debated, it may become necessary in the context of novel disease-modifying drugs. The current symptomatic drugs--cholinesterase inhibitors (CIs) and the NMDA receptor antagonist memantine--are relatively simple to use but their access is limited in many countries by economic considerations and therapeutic nihilism. Although their efficacy is modest, they influence the design of protocols for new drugs since placebo treatment in clinical trials involving patients with established dementia is rarely allowed beyond 3 months. Driving privileges are lost in the moderate stages of dementia, with this decision ideally reached using a standardized assessment algorithm. Physical restraints are still overused in moderate-to-severe stages, but the alternative non-pharmacological therapies and caregiver training programs are not yet fully validated using randomized studies. End-of-life care is slowly moving towards a palliative care approach similar to that for end-stage cancer. There will be new drugs in the near future, some of which will delay progression from prodromal stages to dementia, but their use will require careful stopping rules.

    Teacher self-efficacy refers to the beliefs teachers hold regarding their capability to bring about desired instructional outcomes and may be helpful for understanding and addressing critical issues such as teacher attrition and teacher use of research-supported practices. Educating students with autism likely presents teachers with some of the most significant instructional challenges. The self-efficacy of 35 special education teachers of students with autism between the ages of 3 to 9 years was evaluated. Teachers completed rating scales that represented self-efficacy and aspects of the following 3 of Bandura's 4 sources of self-efficacy: (1) sense of mastery, (2) social persuasions, and (3) physiological/affective states. Significant associations were observed between physiological/affective states and self-efficacy, but no associations were observed for the other sources.

    Full Text Available In this issue of IRJO Akbari and coworkers have introduced and indicated the advantages of “4-horizontal rectus muscle tenotomy on visual function and eye movement records with familial nystagmus syndrome without abnormal head posture and strabismus”. In this prospective study they have shown that tenotomy improves both visual function and eye movements in patients without strabismus and eccentric null point. In the ophthalmic literature various extraocular muscle surgeries on infantile nystagmus syndrome associated with abnormal head posture and eccentric fixation are published and they have been more or less successful.1-3 however, recently some interventional case-series have been published on 4-muscle tenotomy efficacy improving both the vision and the nystagmus which is easier to perform and having less complications highlighting this simple and successful intervention. Beheshtnejad et al reported their experience on “Mid-Term Outcome of Phacoemulsification in Congenital Iris Coloboma”. In this prospective study 19 patients with cataract and congenital iris coloboma have been operated on and followed. The best corrected visual acuity has been improved significantly after the investigation (p<0.0001. Meanwhile, the endothelial cell density has been decreased from 2313/cell/mm2 before surgery to 1361 cells which was also significant.

    Lapadula, Giovanni; Ferraccioli, Gian Franco

    2012-01-01

    Rheumatoid arthritis (RA) societal costs are high because the disease may cause not only restricted joint mobility, chronic pain, fatigue, and functional disability, but also psychological distress. Direct health care costs represent about one-fourth of all costs and are prevalently represented by in-patient care expenditures. The introduction of biologics disease-modifying anti-rheumatic drugs (B-DMARDs), has really changed the perspectives of the patients not fully responding to conventional DMARDs, but the direct costs for drugs has really modified the expenditure for this disease and many other diseases, i.e. psoriatic arthritis, spondyloarthropathies. Increasing pressure for lower cost versions of biological medicines, the scientific technology (particularly analytical technology) that continues to improve will lead to the introduction through reverse ingeneering of biosimilar drugs in rheumatology. The hope is to provide cost savings, which may broaden access to biopharmaceuticals and stimulate further research. The need for patients to have a biosimilar product, with comparable efficacy and safety, will be discussed in this paper along with all the possible issues that will govern the assessment of the bioequivalence and of the interchangeability.

  1. Responding to safety issues in frontotemporal dementias.

    Talerico, K A; Evans, L K

    2001-06-01

    As frontotemporal dementia progresses in individuals, safety issues related to behaviors and injury become a paramount concern. In addition to self-care deficits, frontotemporal dementias are often characterized by behavioral manifestations that include aggression and disinhibition. These behaviors may place the patient and caregivers at risk of injury, stress, and social embarrassment, and frequently lead to institutionalization. Additionally, motor disturbances associated with frontotemporal dementias may contribute to risk of injury from falls. The authors present an integrated biopsychosocial model to guide assessment of needs that may be expressed through behavior. Environmental, behavioral, and psychosocial strategies to assist caregivers in preventing and responding to behaviors and risks are discussed, with the goal of promoting maximum function and quality of life and minimizing caregiver strain. The authors discuss the dangers of physical restraints, which are commonly suggested as a response to fall risk and behavioral symptoms without an awareness of research-based data regarding their lack of efficacy. Benefits and risks of a variety of need-based interventions are presented in a practical, clinically relevant manner. The discussion of diverse safety-enhancing interventions is intended to enable clinicians and caregivers to identify individualized care strategies for patients with frontotemporal dementia.

  2. Micronutrient Fortification of Food: Issues for Asia.

    More than 2 billion individuals globally suffer some degree of deficiency of one or more micronutrients, with the largest numbers in Africa and Asia. Fortification of foods with vitamins and minerals is a proven public health intervention. In Asia, salt iodization, fortified flour and condiments such as fish sauce and soy sauce are reaching hundreds of millions. However, many individuals still do not have adequate intakes of numerous micronutrients, and better fortification strategies and practices will help to alleviate these deficiencies. The International Life Sciences Institute (ILSI) has supported research and scientific dialog about technical and health issues related to micronutrients. Recent studies have indicated widespread vitamin D deficiency among children in SE Asia, and in India. A new trial shows the efficacy of vitamin D-fortified milk in addressing deficiencies, which may have applicability in school feeding programs in India and other parts of Asia. Infant nutrition is also critical, and complementary foods can play an important role after exclusive breastfeeding in providing critical nutrients. A formulation developed in China, Ying Yang Bao, has shown significant reduction of anemia and improved growth in infants. Fortification in Asia has the potential to greatly reduce micronutrient deficiencies and improve health, but more structured efforts are needed to achieve these goals.

    "Research Issues: The Food Environment and Obesity" is an article series commissioned by the American Society for Nutrition and The Obesity Society in an attempt to consider the state of understanding on this topic and identify key knowledge gaps. Roberts and Karl focus on the role of energy density in the regulation of energy intake and body weight and offer recommendations for prioritizing research. Finkelstein et al examine food and beverage purchases as a function of price changes and conclude that targeted food taxes and subsidies alone are unlikely to substantially affect obesity. Pereira points out the difficulty in establishing the strength of the association between intake of sugar-sweetened beverages and weight gain and obesity. Johnson and Wardle review the effects of palatability and variety on eating behavior and weight. Livingstone and Pourshahidi examine the impact of portion size manipulations on energy intake and weight management and find that consumers generally tend to eat proportionally more as portion size increases. Kant focuses on the efficacy and effectiveness of eating frequency manipulation for body weight management and finds that such manipulation has consistently yielded null results. Finally, Gordon-Larsen identifies several limitations of the existing literature regarding neighborhood access to healthy foods.

These associations have led to interest in the potential benefits of mucus clearance techniques in COPD. As Ramos et al1 point out, although the physiological rationale for airway clearance techniques (ACTs in COPD is strong, clinical efficacy has historically been difficult to establish, perhaps due to the variety of techniques and outcomes that have been employed in small studies. We have recently synthesized this body of evidence in a Cochrane systematic review of ACTs for individuals with COPD. The review demonstrated ACTs are safe and meta-analysis showed they confer small beneficial effects on a limited range of important clinical outcomes, such as the need for and duration of ventilatory assistance during an acute exacerbation of COPD (AECOPD.2View original paper by Ramos and colleagues.

  14. Ethical issues in livestock cloning.

    Science.gov (United States)

    Thompson, P B

    1999-01-01

    Although cloning may eventually become an important technology for livestock production, four ethical issues must be addressed before the practice becomes widespread. First, researchers must establish that the procedure is not detrimental to the health or well-being of affected animals. Second, animal research institutions should evaluate the net social benefits to livestock producers by weighing the benefits to producers against the opportunity cost of research capacity lost to biomedical projects. Third, scientists should consider the indirect effects of cloning research on the larger ethical issues surrounding human cloning. Finally, the market structure for products of cloned animals should protect individual choice, and should recognize that many individuals find the prospect of cloning (or consuming cloned animals) repugnant. Analysis of these four issues is complicated by spurious arguments alleging that cloning will have a negative impact on environment and genetic diversity.

  15. Census 2001: issues and perspectives.

    1998-01-01

    This article discusses the Census of India for 2001 and gender issues such as the sex ratio, undercounts of girls, tribe and scheduled caste data, and the data users' conference. The April 1998 conference was attended by representatives of government planning and development departments, research institutions, and statisticians and researchers. Under consideration was a government Ministry of Welfare proposal to reintroduce, after a 60-year hiatus, data by scheduled caste and tribe. This issue is complicated by criteria that vary by state and includability. Quotas for backward classes in educational institutions, government jobs, and in decision-making bodies are the reason for designations by caste. Some groups are distressed because of lack of inclusion as backward classes. M.N. Srinivas strongly advises that counting by caste will create problems for enumerators and will result in lawsuits and violent disturbances. G. Shah argues that caste counts will not weaken the caste system nor expand their political power, but will intensify internal conflicts between the Dalit and Bahujan movements. One other issue is the reintroduction of the 1961 Household schedule which provides family composition by landholding size and household enterprise. Krishnaji advises that this data would help analyze sex ratio imbalances. In 1997, the Core Group examined gender equity issues and operational issues about increasing the scope without increasing costs. The Core Group recommended caste data at the district and sub-district level. Undercounting of the female work force is a continuing issue from the 1991 Census. Suggestions by the Core Group are indicated in brief.

    Full Text Available Applying lean manufacturing philosophy is one of the most important concepts that help enterprises to gain competitive advantage in the world market. Suppliers are an important factor contributing to thesuccess of going lean. Major businesses in India as well as in other world, have been trying to integrate its suppliers to give better performance. In Indian small & medium scale enterprises (SME,application of lean manufacturing strategies especially in terms of supplier integration, have been far fewer. Indian SMEs are still resisting accepting the role of their suppliers to make them leaner. The aim of this study was to identify the supplier issues and their weightage in implementing the lean philosophy in Indian SMEs. The research hypothesizes that there are big opportunities for improvement in the Indian SMEs if it is made leaner by integrating its suppliers in its manufacturing system. Author identified total 21 supplier issues and divided these 21 supplier issues in four categories on conceptual basis named as Supplier Management strategy, Information Sharing with supplier, Supplier Integration, Capability to deal with uncertainty. Mean scores of all four categorized groups of supplier issues are ranked.

  16. Ethical issues in animal cloning.

    Science.gov (United States)

    Fiester, Autumn

    2005-01-01

    The issue of human reproductive cloning has recently received a great deal attention in public discourse. Bioethicists, policy makers, and the media have been quick to identify the key ethical issues involved in human reproductive cloning and to argue, almost unanimously, for an international ban on such attempts. Meanwhile, scientists have proceeded with extensive research agendas in the cloning of animals. Despite this research, there has been little public discussion of the ethical issues raised by animal cloning projects. Polling data show that the public is decidedly against the cloning of animals. To understand the public's reaction and fill the void of reasoned debate about the issue, we need to review the possible objections to animal cloning and assess the merits of the anti-animal cloning stance. Some objections to animal cloning (e.g., the impact of cloning on the population of unwanted animals) can be easily addressed, while others (e.g., the health of cloned animals) require more serious attention by the public and policy makers.

    2017-02-01

    Food insecurity is a significant public health issue that affects the physical and mental health of people of all ages. Higher levels of self-efficacy may reduce levels of food insecurity. In addition, acculturation is potentially an important factor for food insecurity among immigrant populations. The purpose of this study is to examine food insecurity associated with self-efficacy and acculturation among low-income primary care patients in the United States. A self-administered survey was administered in May and June 2015 to uninsured primary care patients (N = 551) utilizing a free clinic that provides free primary care services to low-income uninsured individuals and families in the United States. On average, participants reported low food security. Higher levels of self-efficacy were associated with lower levels of food insecurity. Higher levels of heritage language proficiency were related to lower levels of food insecurity. US-born English speakers, women, and unmarried individuals potentially have higher risks of food insecurity and may need interventions to meet their specific needs. Self-efficacy should be included in nutrition education programs to reduce the levels of food insecurity. Future studies should further examine why these groups have a high risk to better understand needs for interventions.

  18. Debt Issues and Earnings Management

    Directory of Open Access Journals (Sweden)

    Bianca Piloto Sincerre

    2016-01-01

    Full Text Available ABSTRACT The aim of this paper is to analyze earnings management (EM surrounding debenture issues of companies listed on the BM&FBOVESPA. EM is an intentional intervention in external financial reports in order to obtain some private gain. This practice is especially important at the time of issuing debentures because if earnings are inflated, investors may pay an artificially high price. To measure earnings management, current discretionary accruals were used as a proxy, based on the Modified Jones and Modified Jones with ROA econometric models. All of the regressions considered the fixed effects of the companies and the time series effects of the analyses. Evidence was found that companies inflate their financial results in the issuing period in order to positively influence their investors. The results suggest that there is EM in the quarter preceding the issue (t = - 1, indicating the influence that investors may have been under when making the decision to invest in debentures from these companies. In addition, it was verified that companies with higher debt, profitability, and sales growth ratios have higher levels of earnings management. The reputation of the auditor was not statistically significant regarding reductions in the level of management. The results also show that companies listed on Level II and New Market had higher levels of management when considering the Modified Jones with ROA model. Therefore, it can be concluded that there is a greater level of earnings management in companies that issue debentures in the period preceding the event. Finally, the variable that is directly related to the level of earnings management is sales growth.

  19. Evidence on public policy: methodological issues, political issues and examples.

    Science.gov (United States)

    Attanasio, Orazio P

    2014-03-01

    In this paper I discuss how evidence on public policy is generated and in particular the issue of evaluation of public policies. In economics, the issue of attribution and the identification of causal links has recently received considerable attention. Important methodological issues have been tackled and new techniques have been proposed and used. Randomized Control Trials have become some sort of gold standard. However, they are not exempt from problems and have important limitations: in some case they cannot be constructed and, more generally, problems of external validity and transferability of results can be important. The paper then moves on to discuss the political economy of policy evaluations for policy evaluations to have an impact for the conduct of actual policy, it is important that the demand for evaluation comes directly from the policy making process and is generated endogenously within it. In this sense it is important that the institutional design of policy making is such that policy making institutions are incentivized to use rigorous evaluation in the process of designing policies and allocating resources to alternative options. Economists are currently involved in the design and evaluation of many policies, including policies about health, nutrition and education. The role they can play in these fields is not completely obvious. The paper argues that their main contribution is in the modelling of how individual reacts to incentives (including those provided by public policies).

  1. Broken Windows and Collective Efficacy

    Directory of Open Access Journals (Sweden)

    Aldrin Abdullah

    2015-01-01

    Full Text Available The broken windows thesis posits that signs of disorder increase crime and fear, both directly and indirectly. Although considerable theoretical evidence exists to support the idea that disorder is positively related to fear of crime, the empirical literature on examining the indirect effect of the individual’s perception of incivilities on fear of crime is limited, especially in developing countries. This research was conducted to assess the indirect relationship between perceived disorder and fear of crime through collective efficacy. A total of 235 households from Penang, Malaysia, participated in this study. Results reveal that high perception of disorder is negatively associated with collective efficacy. High collective efficacy is associated with low fear of crime. Moreover, a significant and indirect effect of disorder on fear of crime exists through collective efficacy. The results provide empirical support for the broken windows theory in the Malaysian context and suggest that both environmental conditions and interactions of residents play a role in the perceived fear of crime.

Referee efficacy is defined as the extent to which referees believe they have the capacity to perform successfully in their job. Referee efficacy beliefs are hypothesized to be influenced by mastery experiences, referee knowledge/education, support from significant others, physical/mental preparedness, environmental comfort, and perceived anxiety. In turn, referee efficacy beliefs are hypothesized to influence referee performance, referee stress, athlete rule violations, athlete satisfaction, and co-referee satisfaction.

    2015-06-01

    Healthcare professionals can be confronted with a wide range of ethical and regulatory issues in today's ever-changing practice environments. While achieving best practice standards, physical therapists may need to compromise what is best for patients due to fiscally driven rules, regulations, and limited benefits. Scenarios may surface where ethical issues and associated dilemmas become paramount between what is versus what should be. A challenge that should be in the forefront of professional endeavors is staying current with published rules, regulations, and conditions of participation, as applied to various practice models and environments while still adhering to ethical codes. Knowing and utilizing available resources especially American Physical Therapy Association (APTA), websites, documents, and references can strengthen practice patterns and treatment options.

    The field of sport psychology is dynamic and growing. To continue building credibility with the public and allied professionals, effective and ethical practice is crucial. Advances in technology have allowed sport psychology professionals to consult with athletes from a distance, but practitioners must be mindful of their competency to use technology, confidentiality concerns, and the suitability of technology for their clients. Movement toward defining competency and clarifying issues of title usage are additional areas in which the field is gaining momentum. Recent attention has also been drawn to the topics of professional development and cultural competency. With the unique settings in which applied sport psychology practice takes place, attention to multiple relationships is another key ethical issue. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Silva, Fernando; Duarte, Miguel; Correia, Luís; Oliveira, Sancho Moura; Christensen, Anders Lyhne

    2016-01-01

    One of the long-term goals in evolutionary robotics is to be able to automatically synthesize controllers for real autonomous robots based only on a task specification. While a number of studies have shown the applicability of evolutionary robotics techniques for the synthesis of behavioral control, researchers have consistently been faced with a number of issues preventing the widespread adoption of evolutionary robotics for engineering purposes. In this article, we review and discuss the open issues in evolutionary robotics. First, we analyze the benefits and challenges of simulation-based evolution and subsequent deployment of controllers versus evolution on real robotic hardware. Second, we discuss specific evolutionary computation issues that have plagued evolutionary robotics: (1) the bootstrap problem, (2) deception, and (3) the role of genomic encoding and genotype-phenotype mapping in the evolution of controllers for complex tasks. Finally, we address the absence of standard research practices in the field. We also discuss promising avenues of research. Our underlying motivation is the reduction of the current gap between evolutionary robotics and mainstream robotics, and the establishment of evolutionary robotics as a canonical approach for the engineering of autonomous robots.

  9. Methodological issues in grounded theory.

    Science.gov (United States)

    Cutcliffe, J R

    2000-06-01

    Examination of the qualitative methodological literature shows that there appear to be conflicting opinions and unresolved issues regarding the nature and process of grounded theory. Researchers proposing to utilize this method would therefore be wise to consider these conflicting opinions. This paper therefore identifies and attempts to address four key issues, namely, sampling, creativity and reflexivity, the use of literature, and precision within grounded theory. The following recommendations are made. When utilizing a grounded method researchers need to consider their research question, clarify what level of theory is likely to be induced from their study, and then decide when they intend to access and introduce the second body of literature. They should acknowledge that in the early stages of data collection, some purposeful sampling appears to occur. In their search for conceptually dense theory, grounded theory researchers may wish to free themselves from the constraints that limit their use of creativity and tacit knowledge. Furthermore, the interests of researchers might be served by attention to issues of precision including, avoiding method slurring, ensuring theoretical coding occurs, and using predominantly one method of grounded theory while explaining and describing any deviation away from this chosen method. Such mindfulness and the resulting methodological rigour is likely to increase the overall quality of the inquiry and enhance the credibility of the findings.

    This special issue of Journal of Physics B: Atomic, Molecular and Optical Physics is dedicated to the "spectroscopy of transient plasmas" covering plasma conditions produced by a range of pulsed laboratory sources including short and long pulse lasers, pulsed power devices, and free electron lasers (FELs). The full range of plasma spectroscopy up to high energy bremsstrahlung radiation, including line broadening analysis for application to data recorded with the ChemCam instrument on the Mars Science Laboratory rover Curiosity, is covered. This issue is timely as advances in optical lasers and x-ray FELs (XFEL) are enabling transient plasma to be probed at higher energies and shorter durations than ever before. New XFEL facilities being commissioned in Europe and Asia are adding to those operating in the US and Japan and the ELI high power laser project in Europe, due to open this year, will provide short pulse lasers of unprecedented power. This special issue represents a snapshot of the theoretical and experimental research in dense plasmas, electron kinetics, laser-induced breakdown spectroscopy of low temperature plasmas, inertial confinement fusion and non-equilibrium atomic physics using spectroscopy to diagnose plasmas produced by optical lasers, XFELs and pulsed-power machines.

  11. The evolution of controversial issues.

    1994-04-01

    The controversial issues concerning the differences of opinion about the validity of Melanie Klein's theory and technique did not arise suddenly when members of the Viennese Society joined the British Psycho-Analytical Society, before the outbreak of the Second World War. In this paper, I describe briefly the socio-historical, administrative and institutional background out of which these scientific divergences evolved alongside other issues concerned with how long members should hold office in the British Psycho-Analytical Society and therefore be in a position to influence the scientific disagreements and training policy in the Society. These causes for concern among members, which were discussed at five business meetings, are then summarised: they relate to differences of opinion with regard to Melanie Klein's contributions to psychoanalysis, the need for revision of the rules of the Society and the type of training in psychoanalysis that should be offered to candidates. Finally, proposals for different ways of exploring and perhaps dealing with these issues are discussed, including the decision to hold formal scientific discussions of Klein's point of view, once a month. These meetings are now referred to as the 'Controversial Discussions'.

  19. Reading instruction in science: Teachers' practices, beliefs, & self-efficacy

    Science.gov (United States)

    Morales, Christina M.

    The Common Core State Standards (CCSS, 2010) and the Next Generation Science Standards (NGSS, 2013) call on science teachers to play a stronger role in helping students learn from informational science texts. Curriculum implementation efforts aimed at addressing these new standards should build on what teachers are already doing to help students with reading in their classrooms and the pedagogical issues that they feel are important to science learning. However, few current studies have gathered these important insights from science teachers. Aiming to fill this gap in the literature, this study attempted to describe middle school science teachers' current practices, beliefs, and self-efficacy regarding reading and reading instruction in their classrooms. A conceptual model hypothesizing that self-efficacy mediates the relationship between teachers' beliefs about how important reading instruction is to science learning and how often they provide reading instruction in their science classes was also tested. Participants (N = 247) reported that students regularly engaged in reading-related tasks in science class. Somer's D correlation analyses highlighted positive associations between the frequency with which teachers reported that students engaged in various reading-related tasks and the frequency with which they reported providing reading instruction for those tasks, suggesting that students tended to receive explicit instruction or coaching for the reading-related tasks they engaged in most often. Middle school science teachers also expressed positive beliefs about the importance of reading-related tasks and explicit instruction or coaching for reading in science and tended to take on responsibility for helping students become better readers of science texts. Last, a path analysis confirmed that the association between teachers' beliefs and practices was mediated through teachers' self-efficacy (beta = .07, p self-efficacy can influence teacher practice: even if

  20. Gender relations and economic issues.

    Science.gov (United States)

    Elson, D

    1993-10-01

    While most discussions of economic issues pay no explicit attention to gender relations, most economic policy is marked by male bias which provides women with an unequal access to resources. This situation exists because most economists, officials, and business managers lack the imagination to see the gender impact of economic issues and most women's groups and researchers lack the language to portray this connection. This article explores some aspects of this gap and aims to provide women with the ability to effectively discuss economic issues. After an introduction, the article considers the basic problem caused by the fact that the economy is defined primarily in terms of money-making activities. This leads to a male bias since much of women's work occurs outside of the monetary sphere. The next section looks at how a failure to understand the significance of gender relations will interfere with the fulfillment of policy objectives. This discussion is followed by a description of how cutbacks in government expenditures increase the burden on women who must replace the services. Problems with the option of the private-sector replacing government services, such as the fact that increasing disposable income in households does not guarantee that unpaid labor will be reduced and the fact that the private sector may fail to expand in a productive way, are covered. The article then touches on the new emphasis placed by some economists and policy makers on cooperative and interactive solutions to these problems and ends by mentioning three new initiatives which seek to build capacity for gender-aware economic analysis: the development of a training program at Manchester University in the UK, coordination of an international research workshop by the University of Utah in the US, and development of an international association for feminist economics based in the US.

    Full Text Available Facade Design and Engineering is a multidisciplinary field that touches many other scientific disciplines. Glass is one of the key materials for building envelopes, and a strong scientific community has developed over the last decade. Designers love glass for its transparency. It is strong but brittle and very demanding in terms of engineering. We continuously see new innovative developments in terms of its climatic performance, structural possibilities, construction design and new applications. Reason enough to dedicate this special issue to the topic. The issue would not have been possible without the contribution of our special editors Jan Belis and Christian Louter, who contributed through their outstanding editorial work and network. Most of the papers in this issue were carefully selected from of a number of invited submissions and conference papers of the COST Action TU0905 Mid-Term Conference, April 17+18 2013, Porec, (CRC Press/Balkema, Leiden and subsequently subjected to the regular blind review process of the journal. Glass as a building material demonstrates the nature of the architectural discipline, where science and building practice are closely linked. Buildings are the live testing bed for scientific research and, at the same time, building practice formulates new research questions. We found that many articles sent to us deal with this relation. Therefore we decided to introduce the new category ’Applied Practice’ for certain journal paper contributions, which from now on can be found at the end of each issue. Although they do not need to be purely scientific, ’Applied Practice’ papers will always discuss new developments, will have a clear structure and are subjected to the strict JFDE review process. Façade Design and Engineering is a peer reviewed, open access journal, funded by The Netherlands Organisation for Scientific Research NWO (www.nwo.nl.

The thesis of this paper is that the development of a universal and global measure of psychological empowerment may not be a feasible or appropriate goal. I begin by distinguishing between empowerment processes and outcomes. Underlying assumptions are discussed including the notion that empowerment differs across people, contexts, and times. A nomological network that includes intrapersonal, interactional, and behavioral components is also presented. Two examples of psychological empowerment for voluntary service organization members and members of a mutual help organization are described to help illustrate differences in the specific variables that may be used to measure psychological empowerment in different populations and settings.

    In the neighborhood effects literature, collective efficacy is viewed as the key explanatory process associated with the spatial distribution of a range of social problems. While many studies usefully focus on the consequences of collective efficacy, in this paper we examine the task specificity of collective efficacy and consider the individual and neighborhood factors that influence residents' perceptions of neighborhood collective efficacy for specific tasks. Utilizing survey and administrative data from 4,093 residents nested in 148 communities in Australia, we distinguish collective efficacy for particular threats to social order and assess the relative importance of social cohesion and neighborhood social ties to the development of collective efficacy for violence, delinquency and civic/political issues. Our results indicate that a model separating collective efficacy for specific problems from social ties and the more generalized notions of social cohesion is necessary when understanding the regulation potential of neighborhoods.

    Objectives To evaluate student self-efficacy, knowledge and communication with teen issues and learning activities. Methods Data were collected during the 8-week pediatric rotation for third–year medical students at a local children’s hospital. Students completed a self-efficacy instrument at the beginning and end of the rotation; knowledge and communication skills were evaluated during standardized patient cases as part of the objective structured clinical examination. Self-efficacy, knowledge and communication frequencies were described with descriptive statistics; differences between groups were also evaluated utilizing two-sample t-tests. Results Self-efficacy levels of both groups increased by the end of the pediatric rotation, but students in the two-lecture group displayed significantly higher self-efficacy in confidentiality with adolescents (t(35)=-2.543, p=0.02); interviewing adolescents, assessing risk, sexually transmitted infection risk and prevention counseling, contraception counseling were higher with marginal significance. No significant differences were found between groups for communication; assessing sexually transmitted infection risk was marginally significant for knowledge application during the clinical exam. Conclusions Medical student self-efficacy appears to change over time with effects from different learning methods; this higher self-efficacy may increase future comfort and willingness to work with this high-risk, high-needs group throughout a medical career.

    The U.S. National Oceanic and Atmospheric Administration (NOAA) announced the agency's first-ever scientific integrity policy at a 7 December news briefing at the AGU Fall Meeting in San Francisco, Calif. The policy follows a December 2010 White House memorandum that issued guidance to federal agencies implementing scientific integrity policies (see "White House issues scientific integrity policies," Eos Trans. AGU, 91(51), 503, doi:10.1029/2010EO510003, 2010). The purpose of the NOAA policy is "to promote a continuing culture of scientific excellence and integrity, and to establish a policy on the integrity of scientific activities that the agency conducts and uses to inform management and policy decisions," the agency's administrative order states. "In addition, the intent of the policy is to strengthen widespread confidence—from scientists, to decisionmakers, to the general public—in the quality, validity, and reliability of NOAA science and to denote the agency's commitment to a culture of support for excellence of NOAA's principal science asset, its employees."

  20. Regulatory Issues Surrounding Merchant Interconnection

    We discussed various issues concerning the regulatory perspective on private investment in interconnectors. One might claim that leaving investment in transmission infrastructure to competing market parties is more efficient than relying on regulated investment only (especially in the case of long (DC) lines connecting previously unconnected parts of the grids, so that externalities from e.g. loop flows do not play a significant role). We considered that some aspects of interconnection might reduce these market benefits. In particular, the large fixed costs of interconnection construction may lead to significant under investment (due to both first mover monopoly power and the fact that part of generation cost efficiencies realised by interconnection are not captured by the investor itself, and remain external to the investment decision). Second, merchant ownership restricts future opportunities for adaptation of regulation, as would be required e.g. for introduction of potentially more sophisticated methods of congestion management or market splitting. Some of the disadvantages of merchant investment may be mitigated however by a suitable regulatory framework, and we discussed some views in this direction. The issues we discussed are not intended to give a complete framework, and detailed regulation will certainly involve many more specific requirements. Areas we did not touch upon include e.g. the treatment of deep connection costs, rules for operation and maintenance of the line, and impact on availability of capacity on other interconnections.

    A potential challenge for a human Mars mission is that while humans are by most measures the obvious best way to search for life on Mars, we may also be the most problematic in that we could unduly compromise the search for life by contaminating relevant environments and/or possibly adversely and irreversibly affecting indigenous life. Perhaps more problematic is the fundamental epistemic challenge of the "one data point" limitation which could decrease confidence in applying terrestrially based research to extraterrestrial life issues in general. An informal decision tree is presented as one way to begin thinking about contamination issues. There are many sub-questions and distinctions not shown such as biological vs. nonbiological (but biologically relevant) contamination, viable vs. dead organisms, masking indigenous organisms vs. merely making the search more difficult, and independent origin vs. panspermia distinctions. While it may be unlikely that terrestrial microbes could survive on Mars, let alone reproduce and unduly compromise the search for life, the unpredictable potential for microbial life to survive, grow exponentially, evolve and modify (and sometimes destroy) environments, warrants focusing carefully on biologically relevant contamination as we prepare to send humans to the first planet that may have indigenous life-forms.

    Full Text Available (from the introduction Intuition and affect have been neglected topics in the literature on human judgment and decision making for a long time. Judgmental processes involved in risk perception and decision making have traditionally been conceptualized as cognitive in nature, being based upon a rational and deliberate evaluation of the alternatives at hand. This picture started to change in the early 1980s when decision researchers looked beyond rational, deliberate, and cognitive processes and began to investigate intuitive --- as opposed to deliberate --- and emotional --- as opposed to cognitive --- aspects of decision making. In sum, decision research has seen a proliferation of approaches that look beyond rational, deliberate, and purely cognitive processes in decision making and investigate intuitive and emotional judgments in this area. This seemed like a good point in time to reflect the state of this emerging field in a special issue that addresses the question of how intuition and affect are related to each other and how they shape risk perception and decision making. This special issue is the result of a workshop that was held at the University of Bergen in November, 2006.

    Discussion of key electrostatic issues that have arisen during the past few years at KSC that the Electrostatics Laboratory has studied. The lab has studied in depth the Space Shuttle's Thermal Control System Blankets, the International Space Station Thermal Blanket, the Pan/Tilt Camera Blankets, the Kapton Purge Barrier Curtain, the Aclar Purge Barrier Curtain, the Thrust Vector Controller Blankets, the Tyvek Reaction Control System covers, the AID-PAK and FLU-9 pyro inflatable devices, the Velostat Solid Rocket Booster mats, and the SCAPE suits. In many cases these materials are insulating meaning that they might be a source of unsafe levels of electrostatic discharge (ESD). For each, the lab provided in-depth testing of each material within its current configuration to ensure that it does not cause an ESD concern that may violate the safety of the astronauts, the workers and equipment for NASA. For example the lab provides unique solutions and testing such as Spark Incendivity Testing that checks whether a material is capable of generating a spark strong enough to ignite a flammable gas. The lab makes recommendations to changes in specifications, procedures, and material if necessary. The lab also consults with a variety of non-safety related ESD issues for the agency.

    Polypharmacy is a major concern in the care of older adults. People over 65 years of age frequently have multiple medical conditions and may have cancer, which requires multiple medications for treatment. The use of multiple medications increases the risk of drug-drug interactions, non-adherence, and adverse drug reactions. Polypharmacy is a term that refers to a high number of prescribed medications, usually five and above, or the use of more medications than is clinically justified. Although medications are an important factor in improving and maintaining the quality of life of older adults, polypharmacy increases the risks of morbidity and mortality, loss of functional independence, and a multiplicity of cognitive and physical problems in this population. This article examines issues related to polypharmacy in older adults and identifies nursing strategies and interventions to detect and prevent polypharmacy. Nursing strategies discussed include: (1) increasing patient knowledge of pharmacological issues, (2) increasing patient medication management competency, (3) promoting safe patient medication practices, and (4) enhancing patient education. Nurses must be familiar with medicine regimens, understand the primary factors that affect adherence, and participate in continuing education to enhance their ability to safeguard older adult patients.

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

    Improvements in protocol-driven clinical trials and supportive care for children and adolescents with cancer have reduced mortality rates by more than 50% over the past three decades. Overall, the 5-year survival rate for pediatric cancer patients has increased to approximately 80%. Recognition of the biological heterogeneity within specific subtypes of cancer, the discovery of genetic lesions that drive malignant transformation and cancer progression, and improved understanding of the basis of drug resistance will undoubtedly catalyze further advances in risk-directed treatments and the development of targeted therapies, boosting the cure rates further. Emerging new treatments include novel formulations of existing chemotherapeutic agents, monoclonal antibodies against cancer-associated antigens, and molecular therapies that target genetic lesions and their associated signaling pathways. Recent findings that link pharmacogenomic variations with drug exposure, adverse effects, and efficacy should accelerate efforts to develop personalized therapy for individual patients. Finally, palliative care should be included as an essential part of cancer management to prevent and relieve the suffering and to improve the quality of life of patients and their families.

    Full Text Available Generally, quality of life of urban population is heavily dependent on social facilities provided within the environment. One of the most important facilities is transportations. Study on transportation mode in an urban area is especially very important because for almost every individual living in a large and densely populated area, mobility is one of the most crucial issues in everyday life. Enhance mobility, faster journey to work and less pollution from petrol-propelled vehicles can increase the quality of life, which in turn lead to a sustainable urban living. The study present transportation mode usage issues faced by community related to quality of life in an urban area. This study identifies several issues of transportation mode in urban areas and its impact on the quality of life. The study areas are Putrajaya, Kuala Lumpur and Bandar Kajang, Selangor. The methodology used in this research is secondary and primary data. The questionnaires for the survey were distributed from May 2008 to Jun 2008. These researches were conducted on 144 respondents for to evaluate their perception of transportation mode correlated to the quality of life. The collected data were then analyzed using “Statistical Packages for the Social Science” (SPSS. The respondents comprise of 61 males and 84 females from the age group of 18 to 57 years.

    Donahue, Elizabeth

    What factors influence ninth grade students' expectations for success in science? Using social cognitive theory and bioecological systems theory as theoretical frameworks, this dissertation employs data from the High School Longitudinal Study of 2009 (HSLS:09) to examine the relative impact of teacher practices and their perceived attitudes on students' science self-efficacy. Further, as they relate to this broader issue, the relative impact of student subjective task value and teacher characteristics is also investigated. It has been well documented that U.S. students are not achieving at satisfactory levels in science. Education policy has focused on improving science teacher quality as one way to address this problem. Teacher effectiveness has been primarily measured by student achievement on standardized tests. However, not enough attention has been given to the social cognitive factors that can lead to increased achievement and persistence in science as well as how teachers may influence these factors. This study interrogates the relationship between student and teacher variables and the social cognitive construct of self-efficacy, which has proven to have a significant impact on student achievement and persistence in science. Findings add to the current literature surrounding ways that educators may increase student performance in science by employing policies and practices that benefit the development of student science self-efficacy.

  13. Philosophical Issues of Black Holes

    2014-01-01

    Black holes are extremely relativistic objects. Physical processes around them occur in a regime where the gravitational field is extremely intense. Under such conditions, our representations of space, time, gravity, and thermodynamics are pushed to their limits. In such a situation philosophical issues naturally arise. In this chapter I review some philosophical questions related to black holes. In particular, the relevance of black holes for the metaphysical dispute between presentists and eternalists, the origin of the second law of thermodynamics and its relation to black holes, the problem of information, black holes and hypercomputing, the nature of determinisim, and the breakdown of predictability in black hole space-times. I maintain that black hole physics can be used to illuminate some important problems in the border between science and philosophy, either epistemology and ontology.

    Pollination of flowering plants is an important ecosystem service provided by wild insect pollinators and managed honey bees. Hence, losses and declines of pollinating insect species threaten human food security and are of major concern not only for apiculture or agriculture but for human society in general. Honey bee colony losses and bumblebee declines have attracted intensive research interest over the last decade and although the problem is far from being solved we now know that viruses are among the key players of many of these bee losses and bumblebee declines. With this special issue on bee viruses we, therefore, aimed to collect high quality original papers reflecting the current state of bee virus research. To this end, we focused on newly discovered viruses (Lake Sinai viruses, bee macula-like virus), or a so far neglected virus species (Apis mellifera filamentous virus), and cutting edge technologies (mass spectrometry, RNAi approach) applied in the field.

    Social transition causes shifts and changes in the relationship between health professionals and their patients. In their professional capacity, it is important today for nurses to handle ethical dilemmas properly, in a manner that fosters an ethical environment. This article investigates the ethical concerns and decision processes of nurses from a knowledge construction perspective, and examines such issues as patient needs, staff perceptions, organizational benefits, and professional image. The decision making methods commonly used when facing ethical dilemma explored in this study include the traditional problem solving, nursing process, MORAL model, and Murphy's methods. Although decision making for ethical dilemmas is governed by no universal rule, nurses are responsible to try to foster a trusting relationship between employee and employer, health care providers and patients, and the organization and colleagues. When decision making on ethical dilemmas is properly executed quality care will be delivered and malpractice can be reduced.

It was prepared as part of the preparation for the Sustained Spheromak Physics Experiment (SSPX), which addresses these goals: energy confinement and the physics which determines it; the physics of transition from a short-pulsed experiment, in which the equilibrium and stability are determined by a conducting wall (``flux conserver``) to one in which the equilibrium is supported by external coils. Physics is examined in this report in four important areas. The status of present theoretical understanding is reviewed, physics which needs to be addressed more fully is identified, and tools which are available or require more development are described. Specifically, the topics include: MHD equilibrium and design, review of MHD stability, spheromak dynamo, and edge plasma in spheromaks.

    The practice of genetic counselling gives rise to many ethical dilemmas, and counsellors need to be familiar with the principles of biomedical ethics. The primary principles include respect for autonomy, beneficence, non-maleficence and justice. A case of identical twins at 50% risk for Huntington's disease, in which only one twin sought predictive testing for this dominantly inherited disease, created several ethical dilemmas. Another case where predictive testing was carried out on two young children, at high risk, by a laboratory at the request of an adoption agency and a doctor, with a view to giving information to the foster parents, also posed many ethical conundrums for the counsellor. The ethical issues that arose in these cases are discussed in this paper.

  3. ISSUES ON CHINA'S ENERGY SECURITY

    Institute of Scientific and Technical Information of China (English)

    ZHANG Lei; JIANG Wei

    2005-01-01

    For many years, China has made great strides in constructing a sizeable and stable energy supply system rooted mainly in domestic coal supply. That system, however, is subject to immense strain as a result of rapid economic growth, rising living standard, widespread environmental degradation, limited oil reserves and uneven resources distribution. Industrialization and urbanization since the early 1980s have imposed structural constraints on its traditional coal-based energy supply model. Eventually, China became a net oil-importer in 1993 when ten million tons of crude oil and petroleum products from abroad fed into the local economies of the coastal areas. Such a change meant that energy security has become an increasingly sensitive issue to the central government of China. This paper argues that China could benefit from a more open energy supply by striking to a balance of both domestic and international sources, rather than the traditional mode emphasized on a highly self-sufficiency rate.

    Light pollution is generally considered mostly an urban problem. Common sources of light pollution are poorly designed lighting of streets, parking lots, businesses and advertizing signs and for security. These sources, and the amount of light pollution generated, increase with population density. Nevertheless, light pollution can also be significant in rural areas. Rural light pollution differs from that in urban settings, both in the types of pollution and in the means that must be employed to control it. In the country the offending sources are often isolated lights such as from farm barns, vacation cottages, radio and cell phone towers, and road intersections. A culture of strong property rights and privacy rights affects attempts to control rural light pollution. We describe how some of these issues may be addressed based on the results from an Eagle Scout project carried out in central Michigan.

    Full Text Available Nanotechnology is a very vast field which includes a range of technologies at the nano scale, such as pharmaceuticals, biotechnology, genomics, neuroscience, robotics and information technologies. Nanotechnology is the latest technological innovation in global debates on risk regulation and international cooperation. Regulatory bodies have started dealing with the potential risks posed by nanoparticles. Since 2004 the UE has been developing a regulatory policy to tighten control and to improve regulatory adequacy and knowledge of nanotechnology risks. Currently, specific provisions on nanomaterials have been introduced for biocides, cosmetics, food additives, food labelling and materials in contact with foodstuff. The statement that nanotechnologies do inevitably imply ethical questions. The main problems are public trust, potential risks, issues of environmental impact, transparency of information, responsible nanosciences and nanotechnologies research. The aim of this article is to analysis the main problems regulating nanotechnology and some aspects of ethics.

    Numerous factors need to be taken into account when managing a patient with Parkinson's disease (PD) after deep brain stimulation (DBS). Questions such as when to begin programming, how to conduct a programming screen, how to assess the effects of programming, and how to titrate stimulation and medication for each of the targeted sites need to be addressed. Follow-up care should be determined, including patient adjustments of stimulation, timing of follow-up visits and telephone contact with the patient, and stimulation and medication conditions during the follow-up assessments. A management plan for problems that can arise after DBS such as weight gain, dyskinesia, axial symptoms, speech dysfunction, muscle contractions, paresthesia, eyelid, ocular and visual disturbances, and behavioral and cognitive problems should be developed. Long-term complications such as infection or erosion, loss of effect, intermittent stimulation, tolerance, and pain or discomfort can develop and need to be managed. Other factors that need consideration are social and job-related factors, development of dementia, general medical issues, and lifestyle changes. This report from the Consensus on Deep Brain Stimulation for Parkinson's Disease, a project commissioned by the Congress of Neurological Surgeons and the Movement Disorder Society, outlines answers to a series of questions developed to address all aspects of DBS postoperative management and decision-making with a systematic overview of the literature (until mid-2004) and by the expert opinion of the authors. The report has been endorsed by the Scientific Issues Committee of the Movement Disorder Society and the American Society of Stereotactic and Functional Neurosurgery.

  11. The effects of tailoring knowledge acquisition on colorectal cancer screening self-efficacy.

    Jerant, Anthony; To, Patricia; Franks, Peter

    2015-01-01

    Interventions tailored to psychological factors such as personal and vicarious behavioral experiences can enhance behavioral self-efficacy but are complex to develop and implement. Information seeking theory suggests tailoring acquisition of health knowledge (without concurrent psychological factor tailoring) could enhance self-efficacy, simplifying the design of tailored behavior change interventions. To begin to examine this issue, the authors conducted exploratory analyses of data from a randomized controlled trial, comparing the effects of an experimental colorectal cancer screening intervention tailoring knowledge acquisition with the effects of a nontailored control on colorectal cancer screening knowledge and self-efficacy in 1159 patients comprising three ethnicity/language strata (Hispanic/Spanish, 23.4%, Hispanic/English, 27.2%, non-Hispanic/English, 49.3%) and 5 recruitment center strata. Adjusted for study strata, the mean postintervention knowledge score was significantly higher in the experimental group than in the control group. Adjusted experimental intervention exposure (B = 0.22, 95% CI [0.14, 0.30]), preintervention knowledge (B = 0.11, 95% CI [0.05, 0.16]), and postintervention knowledge (B = 0.03, 95% CI [0.01, 0.05]) were independently associated with subsequent colorectal cancer screening self-efficacy (p self-efficacy, with potential implications for tailored intervention design, but this implication requires confirmation in studies specifically designed to examine this issue.

  12. The role of feedback, casual attributions, and self-efficacy in goal revision.

    Science.gov (United States)

    Tolli, Adam P; Schmidt, Aaron M

    2008-05-01

    An important issue in work motivation is how, when, and why individuals revise their goals up or down over time. In the current study, the authors examine feedback, causal attributions, and self-efficacy in this process. Although self-efficacy has frequently been suggested as a key explanatory variable for goal revision, its role has yet to be directly evaluated. Additionally, although attributions have been shown to influence goal revision following failure, the extent to which attributions influence goal revision following success remains unclear. In the current study, the authors address these issues by experimentally manipulating goal progress via performance feedback and tracking the resulting changes in self-efficacy and goal revision over time. In so doing, the authors also address several interpretive ambiguities present in the existing research. Results support the hypothesized model, finding that performance feedback and attributions interactively influenced self-efficacy, which in turn influenced goal revision. These results suggest that interventions targeting attributions, and self-efficacy more directly, may have meaningful influences on goal setting and pursuit, particularly following feedback.

    Posner, J; Kayastha, P; Davis, D; Limoges, J; O'Donnell, C; Yue, K

    2009-01-01

    Adolescent girls in Nepal face enormous social barriers to accessing education and health services due to exclusionary socio-religious traditions and years of conflict. The programme and study reported here address two issues that a national assembly of in-school and out-of-school adolescent girls, who had completed a basic life skills class, and, in the case of unschooled girls, an intensive literacy course, identified as important to their well-being - menstrual restrictions and HIV awareness and prevention. Local non-governmental organizations developed a peer education programme in three districts of Nepal that paired girls from different castes and different educational levels. The programme sought to increase peer educators' (PE) leadership and collective efficacy for informing peers and adults in their communities about the effects that these issues have on women and girls. In total, 504 girls were selected and trained as PEs. They conducted targeted discussion sessions with other girls and organised mass awareness events, reaching 20,000 people. Examination of the effects of participating in the programme on key outcome measures showed that leadership self-efficacy, which was a central theoretical construct for the programme, provided a strong predictor of both increased HIV knowledge and of practicing fewer menstrual restrictions at endline. The project demonstrated that girls from different caste and educational backgrounds are able to work together to change individual behaviour and to address socio-cultural norms that affect their lives and well-being within their communities.

    Behavioral and psychological symptoms of dementia(BPSD) are one of the most disturbing issues in the management of patients, both for caregivers and health care personnel. Aim of this paper is to critically appraise the available guidelines on the non pharmacological management of BPSD. Some effective interventions such as person centred care, communication skills e dementia care mapping are not mentioned while interventions of dubious efficacy (aromatherapy, per therapy, light therapy or music therapy) are proposed. The variability in the expression of behavioral disorders and the different causes suggest an accurate tailoring of the interventions, based on the assessment of the patient, the organization and the environment. Further studies are necessary to improve the implementation of the non drug strategies for the management of BPSDs.

  12. The Efficacy of Soccer Headgear

    2003-01-01

    Objective: The potential for risks associated with chronic soccer heading has led some soccer leagues to mandate the use of soccer headgear. Although manufacturers have designed and promoted these headbands to decrease the forces associated with heading a soccer ball, their efficacy has not been tested. Therefore, we investigated the efficacy of 3 brands of soccer headgear: Headers, Headblast, and Protector, as compared with a non-headband condition. Design and Setting: A force platform was mounted vertically with each headband attached with a length of hook-and-loop tape. A JUGS Soccer Machine projected balls at the platform and headband at 56.45 kph (35 mph). Measurements: We measured vertical ground reaction force for 50 trials of each condition and calculated peak force, time to peak force, and impulse. Results: We found a significant reduction in peak force of impact with all 3 headbands. The Protector headband also showed the greatest decrease in time to peak force and impulse, whereas the Headers headband showed a significant increase in impulse. Conclusions: All 3 headbands were effective at reducing the peak impact force. The Protector headband appeared the most effective at reducing time to peak force and impulse within the design of this study. The clinical effectiveness of these products remains to be seen.

  13. Ethical issues in surgical innovation.

    Science.gov (United States)

    Miller, Megan E; Siegler, Mark; Angelos, Peter

    2014-07-01

    Innovation is responsible for most advances in the field of surgery. Innovative approaches to solving clinical problems have significantly decreased morbidity and mortality for many surgical procedures, and have led to improved patient outcomes. While innovation is motivated by the surgeon's expectation that the new approach will be beneficial to patients, not all innovations are successful or result in improved patient care. The ethical dilemma of surgical innovation lies in the uncertainty of whether a particular innovation will prove to be a "good thing." This uncertainty creates challenges for surgeons, patients, and the healthcare system. By its very nature, innovation introduces a potential risk to patient safety, a risk that may not be fully known, and it simultaneously fosters an optimism bias. These factors increase the complexity of informed consent and shared decision making for the surgeon and the patient. Innovative procedures and their associated technology raise issues of cost and resource distribution in the contemporary, financially conscious, healthcare environment. Surgeons and institutions must identify and address conflicts of interest created by the development and application of an innovation, always preserving the best interest of the patient above the academic or financial rewards of success. Potential strategies to address the challenges inherent in surgical innovation include collecting and reporting objective outcomes data, enhancing the informed consent process, and adhering to the principles of disclosure and professionalism. As surgeons, we must encourage creativity and innovation while maintaining our ethical awareness and responsibility to patients.

  14. Critical issues in burn care.

    Science.gov (United States)

    Holmes, James H

    2008-01-01

    Burn care, especially for serious burn injuries, represents a considerable challenge for the healthcare system. The American Burn Association has established a number of strategies for the management of burn patients and dedicates its efforts and resources to promoting and supporting burn-related research, education, care, rehabilitation, and prevention, often in collaboration with other organizations. The American Burn Association has recommended that patients with serious burns be referred to a designated burn center, ie, a hospital outfitted with specialized personnel and equipment dedicated to burn care. Burn centers have been operational for over 50 years, but the complexity and costs of providing specialized burn care have given rise to a number of critical administrative and political issues. These include logistical limitations imposed by the uneven national distribution of burn centers and a potential shortage of burn beds, both during everyday conditions and in the event of a mass disaster. Burn surgeon shortages have also been identified, stemming, in part, from a lack of specialized burn care training opportunities. There is currently a lack of quality outcome data to support evidence-based recommendations for burn care, and burn care centers are compromised by problems obtaining reimbursement for the care of uninsured and publicly insured out-of-state burn patients. Initiatives are underway to maintain efficient burn care facilities that are fully funded, easily accessible, and most importantly, provide optimal, evidence-based care on a daily basis, and are well-equipped to handle a surge of patients during a disaster situation.

    Full Text Available BACKGROUND: The text deals with terminology issues from an interdisciplinary point of view. It is based on two different disciplines, law and kinanthropology, in an area of their overlap. AIM: The aim of the author is to point out some possible legislative problems, which could arise due to the current reading of the sport supporting act (Act no. 115/2001. The second aim of the author is to contribute to the discussion of kinantropologists (possibly also the educational researchers and lawyers and to stress the importance of the systematic approach to terminology formulation. METHODS: The author uses the method of language interpretation. We also use the basic analytical methods, induction and deduction, while we stress the systematic approach to the term formulation. RESULTS: The analysis of the sport supporting act terminology shows some specific legislative problems, which could arise due to the definition of sport in the sport supporting act. The author discusses a possible alternative solution. CONCLUSION: According to the opinion of the author, clear, obvious and unified terminology of kinantropologists as specialists in their discipline should represent a source, from which other sciences could derive their terminology. Defined and inexpert terminology used in other disciplines should not be used as an argument for its adopting in kinanthropology.

  16. Mitochondrial diseases: advances and issues

    Scarpelli, Mauro; Todeschini, Alice; Volonghi, Irene; Padovani, Alessandro; Filosto, Massimiliano

    2017-01-01

    Mitochondrial diseases (MDs) are a clinically heterogeneous group of disorders caused by a dysfunction of the mitochondrial respiratory chain. They can be related to mutation of genes encoded using either nuclear DNA or mitochondrial DNA. The advent of next generation sequencing and whole exome sequencing in studying the molecular bases of MDs will bring about a revolution in the field of mitochondrial medicine, also opening the possibility of better defining pathogenic mechanisms and developing novel therapeutic approaches for these devastating disorders. The canonical rules of mitochondrial medicine remain milestones, but novel issues have been raised following the use of advanced diagnostic technologies. Rigorous validation of the novel mutations detected using deep sequencing in patients with suspected MD, and a clear definition of the natural history, outcome measures, and biomarkers that could be usefully adopted in clinical trials, are mandatory goals for the scientific community. Today, therapy is often inadequate and mostly palliative. However, important advances have been made in treating some clinical entities, eg, mitochondrial neuro-gastrointestinal encephalomyopathy, for which approaches using allogeneic hematopoietic stem cell transplantation, orthotopic liver transplantation, and carrier erythrocyte entrapped thymidine phosphorylase enzyme therapy have recently been developed. Promising new treatment methods are being identified so that researchers, clinicians, and patients can join forces to change the history of these untreatable disorders. PMID:28243136

  17. Maintenance as a safety issue.

    Science.gov (United States)

    White, Jim

    2008-11-01

    Because safety is related to electrical power systems maintenance, it seems reasonable to assume there could be legal issues if maintenance is not performed. OSHA has not yet taken the stand that not performing maintenance as required by the manufacturer, NFPA 70B, or ANSI/NETA MTS-07 constitutes a willful violation. OSHA defines a willful citation as one where: "the employer knowingly commits with plain indifference to the law. The employer either knows that what he or she is doing constitutes a violation, or is aware that a hazardous condition existed and made no reasonable effort to eliminate it". However, NFPA 70E 2009 requires this maintenance, and OSHA has stated on its Web site that NFPA 70E is "a guide for meeting the requirements of the OSHA electrical regulations". In addition, federal courts have found that NFPA 70E is "standard industry practice." Once a company receives and accepts a willful citation, especially if received as the result of an accident investigation, its worker's compensation protection no longer shields it. One definition given by a trial attorney for a willful citation was that it is equal to negligent behavior. Be smart: Maintain that equipment and save yourself major problems, including unscheduled shutdowns and possible litigation.

    Federal Equal Employment Opportunity laws and regulations do not provide protection from discrimination on the basis of sexual orientation or gender identity or gender expression. Sexual minority astronomers (including lesbian, gay, bisexual and transgender people; LGBT) can face additional challenges at school and work. Studies show that LGBT students on many campuses report experiences of harassment. Cities, counties, and states may or may not have statutes to protect against such discrimination. There is wide variation in how states and insurance plans handle legal and medical issues for transgender people. Federal law does not acknowledge same-sex partners, including those legally married in the U.S. or in other countries. Immigration rules in the U.S. (and many other, but not all) countries do not recognize same-sex partners for visas, employment, etc. State `defense of marriage act' laws have been used to remove existing domestic partner benefits at some institutions, or benefits can disappear with a change in governor. LGBT astronomers who change schools, institutions, or countries during their career may experience significant differences in their legal, medical, and marital status.

    Electrolytes are vital components of an electrochemical energy storage device. They are usually composed of a solvent or mixture of solvents and a salt or a mixture of salts which provide the appropriate environment for ionic conduction. One of the main issues associated with the selection of a proper electrolyte is that its electronic properties have to be such that allow a wide electrochemical window - defined as the voltage range in which the electrolyte is not oxidized or reduced - suitable to the battery operating voltage. In addition, electrolytes must have high ionic conductivity and negligible electronic conductivity, be chemically stable with respect to the other battery components, have low flammability, and low cost. Weak stability of the electrolyte against oxidation or reduction leads to the formation of a solid-electrolyte interphase (SEI) layer at the surface of the cathode and anode respectively. Depending on the materials of the electrolyte and those of the electrode, the SEI layer may be composed by combinations of organic and inorganic species, and it may exert a passivating role. In this paper we discuss the current status of knowledge about electrolyte materials, including non-aqueous liquids, ionic liquids, solid ceramic and polymer electrolytes. We also review the basic knowledge about the SEI layer formation, and challenges for a rational design of stable electrolytes.

    Full Text Available PORTAL opens 2006 with a special selection of papers focusing on the transformative power of social movements. In an age of globalisation and of ideologies of globalism, we debate sources and potential for alternative scenarios, for ‘other worlds.’ Many commentators have proclaimed this the global age, where humanity lives under one world power, one world market, and one world order. Yet many other worlds find new and fertile ground in this age, flourishing against the norm. Social movements set new agendas, inspire participation and crystalise solidarity. At the centre of contestation, they can create emancipatory knowledges—knowledges for change. In this issue of PORTAL we ask how social movements generate new ways of being, new subjectivities, or new modes of existence. We debate the role of affective meaning, of symbolic action and collective conscience, and discuss the place of reflective action. Contributors debate the dialectics between power and counter-power, and the role of strategic conflict and dialogue. They analyse sources of revolutionary and transformative change, discussing the praxis of counter-globalism.

  1. Ethical issues in palliative care.

    Science.gov (United States)

    Randall, F M

    1999-10-01

    The relief of suffering is one of the aims of health care. Pain relief is a moral obligation in health care, not an optional extra. Doctors have moral obligations to strive to relieve pain, to be competent in basic pain control, and to endeavour to give patients an adequate understanding of their illness and painkillers. The most common moral problem in pain control in terminally ill patients is the conflict between the obligation to relieve suffering and the obligation to prolong life. The law prohibits intentionally causing the death of another person. Debates follow as to what constitutes an intention to cause death, and what actually constitutes a cause of death. At present, doctors are legally permitted to give sedatives and analgesics to terminally ill patients with the intention of relieving suffering, even if life is shortened. The moral principle of the 'double effect' relates to this and is explained. It relies on a distinction between intended and foreseen effects of treatment. Some people dispute the distinction between intended and foreseen effects and claim that the principle of double effect allows doctors who intend euthanasia to carry it out under cover of the law. This debate is explored in the article. Finally, is it ever morally justifiable to end the patient's life on the grounds that this is the only way to end pain? Even if it is, should euthanasia be legalised? A brief comment on these issues, and the roles of law and morality, are made.

  2. Current bioethical issues in parasitology.

    2008-09-01

    Parasitic diseases constitute the most common infections among the poorest billion people, entailing high mortality rates and leading to long-term infirmities and poverty. Although the setting-up of public health programs implies many ethical consequences, the range of specific questions in parasitology that can be attributed to bioethics remains, to a large extent, unexplored. From the present analysis, it emerged three main issues which characterize ethical stakes in parasitology: accounting the complexity of the field of intervention, putting the principle of justice into practice and managing the changing context of research. From the research angle, medical parasitology-mycology, as other biological disciplines, is undergoing tensions derived from biological reductionism. Thanks to its links with the history and philosophy of the sciences, bioethics can help to clarify them and to explain the growing hold that technologies have over scientific thinking. On the whole, researchers as well as clinicians are called on to assume a specific responsibility, proportional to their competence and their place in the making of scientific, health, economic and social decisions.

  3. Energy issues in desalination processes.

    2008-11-15

    Water, energy, and environmental issues are closely related. New water techniques consume energy, and innovative renewable energy techniques using biofuels and biodiesel consume an incredible amount of water. Different desalination techniques that consume different energy levels from different sources are in use today. Some people, environmentalists, decision makers, and even scientists, mainly in nonscientific publications, consider energy consumption in desalination to be too high and are seeking new ways of reducing it, which often involves increasing capital investment. Efforts should be directed at reducing not only energy consumption but also total water cost. A competent grasp of thermodynamics and heat and mass transfer theory, as well as a proper understanding of current desalination processes, is essential for ensuring beneficial improvements in desalination processes. Thermodynamics sets the absolute minimum limit of the work energy required to separate water from a salt solution. Unavoidable irreversibilities augment the actual energy consumption, yet modern desalination techniques have succeeded in considerably narrowing the gap between actual and limiting energy levels. The implication of this smaller gap is that only marginal energy reductions are possible. The current energy consumption of different desalination processes is reviewed in this paper. A comparison with other common energy-consuming ventures leads to some interesting conclusions.

    Biomonitoring requires the application of batteries of different biomarkers, as environmental contaminants induce multiple responses in organisms that are not necessarily correlated. Omic technologies were proposed as an alternative to conventional biomarkers since these techniques quantitatively monitor many biological molecules in a high-throughput manner and thus provide a general appraisal of biological responses altered by exposure to contaminants. As the studies using omic technologies increase, it is becoming clear that any single omic approach may not be sufficient to characterize the complexity of ecosystems. This work aims to provide a preliminary working scheme for the use of combined transcriptomic and proteomic methodologies in environmental biomonitoring. There are difficulties in working with nonmodel organisms as bioindicators when combining several omic approaches. As a whole, our results with heterologous microarrays in M. spretus and suppressive subtractive hybridization (SSH) in P. clarkii indicated that animals sustaining a heavy pollution burden exhibited an enhanced immune response and/or cell apoptosis. The proteomic studies, although preliminary, provide a holistic insight regarding the manner by which pollution shifts protein intensity in two-dimensional gel electrophoresis (2-DE), completing the transcriptomic approach. In our study, the sediment element concentration was in agreement with the intensity of protein expression changes in C. maenas crabs. In conclusion, omics are useful technologies in addressing environmental issues and the determination of contamination threats.

  5. Sampling Issues in Bibliometric Analysis

    Williams, Richard

    2014-01-01

    Bibliometricians face several issues when drawing and analyzing samples of citation records for their research. Drawing samples that are too small may make it difficult or impossible for studies to achieve their goals, while drawing samples that are too large may drain resources that could be better used for other purposes. This paper considers three common situations and offers advice for dealing with each. First, an entire population of records is available for an institution. We argue that, even though all records have been collected, the use of inferential statistics and significance testing is both common and desirable. Second, because of limited resources or other factors, a sample of records needs to be drawn. We demonstrate how power analyses can be used to determine in advance how large the sample needs to be to achieve the study's goals. Third, the sample size may already be determined, either because the data have already been collected or because resources are limited. We show how power analyses c...

  6. Acetaminophen: old drug, new issues.

    Aminoshariae, Anita; Khan, Asma

    2015-05-01

    The purpose of this review was to discuss new issues related to safety, labeling, dosing, and a better understanding of the analgesic effect of acetaminophen. The MEDLINE, Embase, Cochrane, and PubMed databases were searched. Additionally, the bibliography of all relevant articles and textbooks were manually searched. Two reviewers independently selected the relevant articles. Concerns about acetaminophen overdose and related liver failure have led the US Food and Drug Administration to mandate new labeling on acetaminophen packaging. In addition, large-scale epidemiologic studies increasingly report evidence for second-generation adverse effects of acetaminophen. Prenatal exposure to acetaminophen is associated with neurodevelopmental and behavioral disorders. Recent studies also suggest that acetaminophen is a hormone disrupter (ie, it interferes with sex and thyroid hormone function essential for normal brain development) and thus may not be considered a safe drug during pregnancy. Finally, emerging evidence suggests that although the predominant mechanism by which acetaminophen exerts its therapeutic effect is by inhibition of cyclooxygenase, multiple other mechanisms also contribute to its analgesic effect. Available evidence suggests that indiscriminate usage of this drug is not warranted. and its administration to a pregnant patient should be considered with great caution.

    It is now 23 years since the first Topical Meeting "Nonlinear Guided Wave Phenomena" (Houston, TX, February 2-4, 1989) has been organised by George Stegeman and Allan Boardman with support of the Optical Society of America. These series of the OSA conferences known as NLGW, continued under the name "Nonlinear Photonics" starting from 2007. The latest one, in Colorado Springs in June 17-21, 2012 has been a great success despite the fierce fires advancing around the city at the time of the conference. This Focus issue is a collection of several papers presented at the conference with extended content submitted to Optics Express. Although this collection is small in comparison to the total number of papers presented at the conference, it gives a flavor of the topics considered at the meeting. It is also worthy to mention here that the next meeting "Nonlinear Photonics" is planned to be held in Barcelona - one of the main European centers on this subject.

    This thesis is an attempt to raise some ethical issues that are specific to phase IV drug trials and to provide preliminary responses to such issues. We limited ourselves to issues of informed consent, risk-benefit assessment, and the therapeutic orientation of phase IV. On the issue of informed consent (IC) and phase IV, we deliberated on issues related to form and procedure. First, we demonstrated that in phase IV non-interventional studies, though IC remains the standard, the manner of col...

    2008-04-01

    The study was designed to test the relationship of principals' transformational, transactional, and laissez-faire leadership with teachers' collective efficacy. Bandura's theory of efficacy applied to the group and Bass's transformational leadership theory were used as the theoretical framework. Participants included 487 French Canadian teachers from 40 public high schools. As expected, there were positive and significant correlations between principals' transformational and transactional leadership and teachers' collective efficacy. Also, there was a negative and significant correlation between laissez-faire leadership and teachers' collective efficacy. Moreover, regression analysis showed transformational leadership significantly enhanced the predictive capabilities of transactional leadership on teachers' collective efficacy. These results confirm the importance of leadership to predict collective efficacy and, by doing so, strengthen Bass's theory of leadership.

    international scientific community to support ICC and join its activities (Chernobyl Center 2006). In December 1995, a memorandum of understanding (MOU) on the ChNPP closure was signed by the government of Ukraine, all of the G7 governments, and the European Commission. The ICC foundation was considered critical to ensure the safe decommissioning of the ChNPP reactor units and improvement of the safety of the Chernobyl Containment Shelter. On the 10th anniversary of the Chernobyl accident (26 April 1996), Mr. Viktor Yushchenko, the President of Ukraine, issued a decree to establish the Chernobyl Center for Nuclear Safety, Radioactive Waste and Radioecology (Chernobyl Center). On the same day, a MOU involving the US participation in Chernobyl Center activities was signed by the US and Ukraine (Chernobyl Center 2006). In July 1998, the US and Ukraine signed an agreement to establish the International Radioecology Laboratory (IRL) as part of the Chernobyl Center. The creation of IRL was a logical continuation of previous programs to conduct scientific research in radioecology and provide Ukraine and the rest of the world with the necessary infrastructure and scientific basis to conduct research in radioecology, radiobiology, dosimetry, and environmental protection in the ChEZ (Chernobyl Center 2006). A recent collaborative effort with IRL has been implemented through a project titled 'Long-term impacts from radiation/contamination within the Chernobyl Exclusion Zone' (Farfan et al. 2008; Gerdes et al. 2009; Marra et al. 2010). This collaboration had the following objectives: (1) Assess the long-term impacts to the environment from radiation exposure within the ChEZ; (2) Provide information on remediation guidelines and ecological risk assessment within radioactively contaminated territories based on the results of long-term field monitoring, analytical measurements, and numerical modeling of soils and groundwater radioactive contamination; and (3) Recommend the

  12. Materials issues in fusion reactors

    2010-02-01

    The world scientific community is presently engaged in one of the toughest technological tasks of the current century, namely, exploitation of nuclear fusion in a controlled manner for the benefit of mankind. Scientific feasibility of controlled fusion of the light elements in plasma under magnetic confinement has already been proven. International efforts in a coordinated and co-operative manner are presently being made to build ITER - the International Thermonuclear Experimental Reactor - to test, in this first step, the concept of 'Tokamak' for net fusion energy production. To exploit this new developing option of making energy available through the route of fusion, India too embarked on a robust fusion programme under which we now have a working tokamak - the Aditya and a steady state tokamak (SST-1), which is on the verge of functioning. The programme envisages further development in terms of making SST-2 followed by a DEMO and finally the fusion power reactor. Further, with the participation of India in the ITER program in 2005, and recent allocation of half - a - port in ITER for placing our Lead - Lithium Ceramic Breeder (LLCB) based Test Blanket Module (TBM), meant basically for breeding tritium and extracting high grade heat, the need to understand and address issues related to materials for these complex systems has become all the more necessary. Also, it is obvious that with increasing power from the SST stages to DEMO and further to PROTOTYPE, the increasing demands on performance of materials would necessitate discovery and development of new materials. Because of the 14.1 MeV neutrons that are generated in the D+T reaction exploited in a tokamak, the materials, especially those employed for the construction of the first wall, the diverter and the blanket segments, suffer crippling damage due to the high He/dpa ratios that result due to the high energy of the neutrons. To meet this challenge, the materials that need to be developed for the tokamaks

They can be related to mutation of genes encoded using either nuclear DNA or mitochondrial DNA. The advent of next generation sequencing and whole exome sequencing in studying the molecular bases of MDs will bring about a revolution in the field of mitochondrial medicine, also opening the possibility of better defining pathogenic mechanisms and developing novel therapeutic approaches for these devastating disorders. The canonical rules of mitochondrial medicine remain milestones, but novel issues have been raised following the use of advanced diagnostic technologies. Rigorous validation of the novel mutations detected using deep sequencing in patients with suspected MD, and a clear definition of the natural history, outcome measures, and biomarkers that could be usefully adopted in clinical trials, are mandatory goals for the scientific community. Today, therapy is often inadequate and mostly palliative. However, important advances have been made in treating some clinical entities, eg, mitochondrial neuro-gastrointestinal encephalomyopathy, for which approaches using allogeneic hematopoietic stem cell transplantation, orthotopic liver transplantation, and carrier erythrocyte entrapped thymidine phosphorylase enzyme therapy have recently been developed. Promising new treatment methods are being identified so that researchers, clinicians, and patients can join forces to change the history of these untreatable disorders.

There are also some issues that I would like to communicate to you in this first issue of the new year. Farewell to Editorial Board members In 2005 the terms of office of half the Editorial Board came to an end. We would like to thank them for their wise advice on difficult questions, the innumerable cases where they have acted as adjudicators and for the many other forms of support they have given to the journal. While we say farewell to them as Board members, we trust that they will continue to support Nuclear Fusion. H. Bolt M.J. Fujiwara G.T. Hoang G.S. Lee S. Nakai R.R. Parker O.S. Pavlichenko S.C. Prager V.P. Smirnov M.Q. Tran Y. Wan Our special thanks go to F. (Rip) Perkins who chaired the Board for many years and was instrumental in many important Board decisions. We welcome the new members of the Editorial Board which met in its new composition (see the prelim pages) during the EPS conference in Tarragona under the chairmanship of M. Kikuchi. Refereeing As we did last year we would like to thank our top ten most loyal referees who have helped the journal with its double-referee peer-review procedure in the last year. At the Nuclear Fusion Editorial Office we are fully aware of the load we put on the shoulders of our referees. At the end of 2004 the Editorial Board decided that a gesture of gratitude should be made to our top ten most loyal referees. We offer them a personal subscription to Nuclear Fusion with electronic access for one year, free of charge. To select the top ten referees we have adopted the criterion that a researcher should have acted as a referee or adjudicator for at least three different manuscripts during the period autumn 2004 to autumn 2005. According to our records the following people, excluding our Board members, met this criterion. Congratulations and many, many thanks! D. van Eester (ERM/KMS, Belgium) L.R. Grisham (PPPL, USA) C.

    BACKGROUND: The concept of the "efficacy-effectiveness gap" (EEG) has started to challenge confidence in decisions made for drugs when based on randomized controlled trials alone. Launched by the Innovative Medicines Initiative, the GetReal project aims to improve understanding of how to reconcile...... paradigms, in which EEG is related to 1) real-life characteristics of the health care system; 2) the method used to measure the drug's effect; and 3) a complex interaction between the drug's biological effect and contextual factors. CONCLUSIONS: The third paradigm provides an opportunity to look beyond any...... dichotomy between "standardized" versus "real-life" characteristics of the health care system and study designs. Namely, future research will determine whether the identification of these contextual factors can help to best design randomized controlled trials that provide better estimates of drugs...

    Self-efficacy is defined as a person's beliefs in his or her abilities to successfully complete a task, and has been shown to influence student motivation and academic achievement. The purpose of this study was to evaluate the impact of a new European teaching module in occupational medicine on undergraduate students' self-efficacy and knowledge in the subject matter. Pre-, in-between, and posttraining tests were used to assess self-efficacy and knowledge building of 261 third-year medical students on occupational health issues. Determinants of self-efficacy and knowledge were also identified. Repeated measurement data were analyzed with multilevel statistical procedures. The level of self-efficacy and knowledge in occupational medicine increased after the training. Students who frequently attended the lectures scored significantly higher than sporadic attendees. There was no relation between the level of self-efficacy and the final knowledge score. Teaching with the new occupational medicine module was effective. Lecture attendance is an important determinant of self-efficacy and performance. Self-efficacy was not associated with knowledge score. Encouraging classroom participation may enhance student achievement.

  19. Issues of therapeutic communication relevant for improving quality of care.

    Popa-Velea, O; Purcărea, V L

    2014-01-01

    Communication issues are extensively considered a topic of high interest for improving the efficacy of the therapeutic act. This article aimed to overview several issues of therapeutic communication relevant for improving quality of care. A number of 15 bibliographic resources on these topics published in peer-reviewed journals between 1975 and 2010, and indexed in PubMed, ProQuest and EBSCO databases were examined, to seek for evidence regarding these data. Results highlight a number of communication problems commonly reported in the literature, such as the lack of physician communicational skills or their deterioration, the persistence of an asymmetric therapeutic communicational model, communication obstacles brought by the disease itself or by several variables pertaining to the patient, including specific demographic and psychological contexts. Equally, literature reports ways of improving therapeutic communication, such as optimizing the clinical interview, better time management techniques or assertiveness. Integration of communication training in the bio-psycho-social model of care and monitoring parameters like adherence and quality of life as tools reflecting also a good therapeutic communication can be valuable future approaches of obtaining better results in this area.

  20. Assessment of biotechnology drugs: what are the issues?

    1999-06-01

    Biotechnology is increasingly regarded as an important reservoir for the development of new and innovative, but generally expensive, pharmaceuticals. At the same time, concerns about cost containment have triggered a keen interest in evaluating and comparing the values of diverse health care interventions. In this paper we studied the process of assessment and diffusion of biotechnology drugs by studying three cases, i.e. nebacumab, colony stimulating factors and recombinant human growth hormone. These cases are evaluated in a standardised format, concerning safety, efficacy, cost-effectiveness and ethical, legal and social issues. Many factors that determine the fate of a biotechnology drug seemed to be similar to those of 'classical' drugs. The definition and measurement of clinically relevant outcomes has been identified as a key factor in the assessment process. Another important issue is the relatively small population for the primary indications of biotechnology drugs and the subsequent process of broadening of indications. Paradoxically, the current trend towards evidence-based medicine means that we will increasingly have to make decisions based on 'incomplete' knowledge'.

  1. Teen theaters grapple with issues.

    Science.gov (United States)

    Pugni, J L

    1984-01-01

    At this time there are about 20 Planned Parenthood teen theater groups throughout the US. The idea originated in New York in 1973, when the staff of the Family Planning Division of the New York Medical College needed an effective way to reach adolescents about important issues. FOCUS, a teen family life theater sponsored by Planned Parenthood of Greater Charlotte, performs skits about life as seen from the teenager's perspective. The teenagers do not use a script but create their performances from their own experiences, expressed through carefully learned improvisational techniques. This approach gives the presentations an authentic flavor that enables the troupe to connect with the audience. The topics dealt with vary. For example, 1982-83 shows included peer pressure, divorce, teenage pregnancy, drinking, teenage suicide, parent-teen relationships, and loneliness. The performances do not offer absolute answers but rather pose important questions to the audience. Following the performance the actors and actresses return to the stage, still portraying their characters, and invite the audience to ask questions and discuss possible alternatives for the characters. THE SOURCE is the Teen Council of Planned Parenthood of Southwest Florida. It works to inform the community of problems teenagers face by presenting short plays, written, directed, and cast by teens themselves. Through education, honest answers, healthy building of self esteem, and parent support, SOURCE members reach a higher level of self awareness. They then share what they learn with their families, peers, and the community through performance and special events. THE SOURCE, formed in October 1980, grew out of Planned Parenthood's belief that if teens feel self worth, their decision-making process will be affected less by peer pressure and negative social influences. The Youth Expression Theater (YET) of Cambridge is an education outreach project of the Planned Parenthood League of Massachusetts (PPLM

    competitive pressures found in the private sector, social organizations lack the personal accountability needed to foster the development of an effective marketing function. The challenges or problems confronting social marketing are not insurmountable. The application of the discipline for the promotion of social issues, ideas, and causes is likely to continue to grow. A need exists for a more common process of social agencies to apply marketing tools and techniques. Another need is for improved training of social marketing managers.

  3. Oilsand tailings : solving the issues

    Energy Technology Data Exchange (ETDEWEB)

    Granson, E.

    2008-11-15

    Oilsands tailings management is an integral part of oil sands research and development. Studies to decrease land disturbance and to resolve environmental and safety issues are underway at several government agencies and industry groups, including the Alberta Energy Research Institute, the Oil Sands Tailings Research Facility and Natural Resources Canada's CANMET Advanced Separation Technologies division. Fresh tailings that come from the bitumen extraction process are composed of 85 to 90 per cent water and 10 to 15 per cent solids having the consistency of muddy water. The 3 zones that develop following discharge into the tailings ponds are 3 metres of clear water; residual hydrocarbons that float on the surface; and, a 1 metre zone of water and settling clay particles known as mature fine tailings (MFT) which comprise about 90 per cent of the volume of the tailings pond. The tailings ponds must be built in areas where there is no bitumen suitable for surface mining. The impounded area is surrounded by tailings dykes built from local overburden materials. As such, tailings ponds are managed as dams according to Alberta Dam Safety regulation requirements. Dam stability is increased by the installation of internal seepage control measures. This article described the key guidelines and objectives for the construction of tailings ponds. It also described the 3 primary types of reclamation settings, namely aquatic reclamation, wetland reclamation and terrestrial reclamation. Water removed from the MFT can be recycled back to the plant to reduce the amount of water used from the river. Although this contributes to lower energy costs, there are challenges regarding salt levels that builds up in piping and equipment. The presence of water in the tailings also prevents tailings reclamation. In addition to mechanical systems to remove water, researchers are also considering the use of chemicals and natural processes. In the consolidated tailings (CT) process, the

  4. Issues in fuel cell commercialization

    Science.gov (United States)

    Appleby, A. J.

    After 25 years of effort, the phosphoric acid fuel cell (PAFC) is approaching commercialization as cell stack assemblies (CAS) show convincingly low degradation and its balance-of-plant (BOP) achieves mature reliability. A high present capital cost resulting from limited cumulative production remains an issue. The primary PAFC developer in the USA (International Fuel Cells, IFC) has only manufactured 40 MW of PAFC components to date, the equivalent of a single large gas turbine aero-engine or 500 compact car engines. The system is therefore still far up the production learning curve. Even so, the next generation of on-site 40% electrical efficiency (LHV) combined heat-and-power (CHP) PAFC system was available for order from IFC in 1995 at US 3000/kW (1995). To effectively compete in the marketplace with diesel generators, the dispersed cogeneration PAFC must cost approximately US 1550/kW (1995) in the USA and Europe. At somewhat lower costs than this, dispersed cogeneration PAFCs will compete with large combined-cycle generators. However, in Japan, costs greater than US 2000/kW will be competitive, based on the late-1995 trade exchange rate of 100-105 Yen/US ). The perceived advantages of fuel cell technologies over developments of more conventional generators (e.g., ultra-low emissions, siting) are not strong selling points in the marketplace. The ultimate criterion is cost. Cost reduction is now the key to market penetration. This must include reduced installation costs, for which the present goal is US$ 385/kW (1995). How further capital cost reductions can be achieved by the year 2000 is discussed. Progress to date is reviewed, and the potential for pressurized electric utility PAFC units is determined. Markets for high-temperature fuel cell system (molten carbonate, MCFC, and solid oxide, SOFC), which many consider to be 20 and 30 years, respectively, behind the PAFC, are discussed. Their high efficiency and high-quality waste heat should make them attractive

Two characteristics related to teachers were examined: teachers' years of teaching experience and teachers' highest degree. Participants included 62 mathematics and science teachers from three school districts in Northwest Arkansas. When comparing fifth grade mathematics and science teachers' efficacy beliefs based on their highest degree, a significant difference in teachers' efficacy beliefs was found based on their degrees. Teachers with a Bachelor degree have higher total efficacy than teachers who hold Master's degrees. Moreover, an investigation to determine if there is a difference in mathematics and science teachers' efficacy beliefs in the three subscale of teachers' efficacy (for classroom management, for student engagement, and for instructional strategies) revealed a significant difference in teachers' efficacy for two of the three constructs. However, when examining teachers' sense of efficacy based on their teaching experience, no differences in teachers' efficacy were found. A correlation was conducted and the results indicated that there was no significant relationship between fifth grade teachers' sense of efficacy and students' achievement in the benchmark test in mathematics and science. The recommendations from this study should be used to inform other scholars and administrators of the importance of teachers' sense of efficacy in order to improve students' achievement gains.

    2011-08-01

    This research examined the relative effects of other-efficacy and self-efficacy beliefs in relation to individual performance within a cooperative dyadic setting. Pairs of female participants (M(age) = 20.08, SD = 1.93) performed three practice trials on a dyadic dance-based videogame. Other-efficacy and self-efficacy beliefs were then manipulated through the provision of bogus feedback regarding each pair member's coordination abilities. Following the administration of this feedback, pairs performed a final trial on this dance-based task. The results revealed a main effect for other-efficacy, such that participants in the enhanced other-efficacy conditions outperformed those in the inhibited other-efficacy conditions on this task. A main effect for self-efficacy was not observed. Furthermore, there was no evidence of an interaction between other-efficacy and self-efficacy. The results of this study suggest that other-efficacy may supersede the effects of self-efficacy in supporting personal performance within cooperative relational contexts.

  12. FOREWORD: Special issue on mass

    Science.gov (United States)

    Gläser, Michael

    2003-12-01

    This special issue is intended to present a review of mass standards, mass determination and the efforts to replace the international prototype of the kilogram by a new definition of the kilogram based on a fundamental constant of physics. Mass is a quantity that is familiar to everybody primarily for its importance in commerce. It is not only one of the traditional quantities of metrology but also of science in general. The unit of mass has always been based on a material object and, since 1889, on the international prototype of the kilogram. The mass of any standard weight is derived from this prototype by a cascade of comparison measurements using balances. The sources of uncertainty of the mass of a standard depend upon the circumstances of the weighing process and the long-term instabilities of the intermediate standards. The international prototype—its mass is one kilogram by definition—may also suffer from instabilities or drifts in time, but until now it has not been possible to check this by comparison with a fundamental constant in physics. Repeated verifications of some 40 or so national prototypes of the members of the Metre Convention have shown significant drifts with an average of about 50 µg within 100 years, a fact that casts doubt on the stability of the international prototype itself. Experiments have been underway for about 30 years on linking fundamental constants such as the Avogadro constant or, correspondingly, the atomic mass unit and Planck's constant to the kilogram. Relative uncertainties of the order of 10-7 have been reached today, still one order of magnitude too large for monitoring the stability of the international prototype or for a new definition. The first article of this special issue gives information on the international and the national prototypes of the kilogram, its material, manufacture, cleaning procedures, stability investigations and the periodic verifications of national prototypes. The next article describes

    The focus of this investigation was to identify issues central to increasing the involvement of small minority businesses (MBs) in federal or prime contracts with the Department of Energy (DOE), as a foundation for designing a program to assist buyers of contracted goods and services. The approach to determining issues involved interviewing the owners of 15 MBs, representing a range of businesses, and buyers and purchasing officers from three large DOE prime contractors. The interviewees identified issues related to positive working relationships and rated a predetermined set of 27 potential MB-DOE problems regarding their existence and criticalness. The issues identified by MBs were of two broad types. The predominant issues and barriers were associated with their being small businesses. Secondary issues reflected the disadvantaged status of the business (woman and/or minority-owned).

  14. Ethical issues occurring within nursing education.

    Fowler, Marsha D; Davis, Anne J

    2013-03-01

    The large body of literature labeled "ethics in nursing education" is entirely devoted to curricular matters of ethics education in nursing schools, that is, to what ought to be the ethics content that is taught and what theory or issues ought to be included in all nursing curricula. Where the nursing literature actually focuses on particular ethical issues, it addresses only single topics. Absent from the literature, however, is any systematic analysis and explication of ethical issues or dilemmas that occur within the context of nursing education. The objective of this article is to identify the spectrum of ethical issues in nursing education to the end of prompting a systematic and thorough study of such issues, and to lay the groundwork for research by identifying and provisionally typologizing the ethical issues that occur within the context of academic nursing.

    2007-04-01

    In this article, we describe development of a Physics Self-Efficacy Scale (PSES) that is a self-administered measure to assess physics self-efficacy beliefs regarding one's ability to successfully perform physics tasks in physics classroom. The scale is initially composed of 56 items prepared following a brief scrutiny of relating literature on self-efficacy. It was initially administered 30 physics teacher candidates and was also examined by 6 experts of physics education, then ambiguous or incomprehensible 6 items were dismissed. This PSES was tested on 558 undergraduate students all completed fundamental physics courses. Cronbach's Alpha reliability coefficient of the PSES was calculated as 0.94. The final version of the PSES contained 30 items with 5 dimensions namely, 1. Self-efficacy towards solving physics problems, 2. Self-efficacy towards physics laboratory, 3. Self-efficacy towards learning physics, 4. Self-efficacy towards application of physics knowledge and 5. Self-efficacy towards memorizing physics knowledge.

    Excler, Jean-Louis; Michael, Nelson L

    2016-11-01

    Only four HIV-1 vaccine concepts have been tested in six efficacy trials with no product licensed to date. Several scientific and programmatic lessons can be learned from these studies generating new hypotheses and guiding future steps. RV144 [ALVAC-HIV (canarypox vector) and AIDSVAX B/E (bivalent gp120 HIV-1 subtype B and CRF01_AE)] remains the only efficacy trial that demonstrated a modest vaccine efficacy, which led to the identification of immune correlates of risk. Progress on subtype-specific, ALVAC (canarypox vector) and gp120 vaccine prime-boost approaches has been slow, but we are finally close to the launch of an efficacy study in Africa in 2016. The quest of a globally effective HIV-1 vaccine has led to the development of new approaches. Efficacy studies of combinations of Adenovirus type 26 (Ad26)/Modified Vaccinia Ankara (MVA)/gp140 vaccines with mosaic designs will enter efficacy studies mid-2017 and cytomegalovirus (CMV)-vectored vaccines begin Phase I studies at the same time. Future HIV-1 vaccine efficacy trials face practical challenges as effective nonvaccine prevention programs are projected to decrease HIV-1 incidence. An HIV-1 vaccine is urgently needed. Increased industry involvement, mobilization of resources, expansion of a robust pipeline of new concepts, and robust preclinical challenge studies will be essential to accelerate efficacy testing of next generation HIV-1 vaccine candidates.

In December 1995, a memorandum of understanding (MOU) on the ChNPP closure was signed by the government of Ukraine, all of the G7 governments, and the European Commission. The ICC foundation was considered critical to ensure the safe decommissioning of the ChNPP reactor units and improvement of the safety of the Chernobyl Containment Shelter. On the 10th anniversary of the Chernobyl accident (26 April 1996), Mr. Viktor Yushchenko, the President of Ukraine, issued a decree to establish the Chernobyl Center for Nuclear Safety, Radioactive Waste and Radioecology (Chernobyl Center). On the same day, a MOU involving the US participation in Chernobyl Center activities was signed by the US and Ukraine (Chernobyl Center 2006). In July 1998, the US and Ukraine signed an agreement to establish the International Radioecology Laboratory (IRL) as part of the Chernobyl Center. The creation of IRL was a logical continuation of previous programs to conduct scientific research in radioecology and provide Ukraine and the rest of the world with the necessary infrastructure and scientific basis to conduct research in radioecology, radiobiology, dosimetry, and environmental protection in the ChEZ (Chernobyl Center 2006). A recent collaborative effort with IRL has been implemented through a project titled 'Long-term impacts from radiation/contamination within the Chernobyl Exclusion Zone' (Farfan et al. 2008; Gerdes et al. 2009; Marra et al. 2010). This collaboration had the following objectives: (1) Assess the long-term impacts to the environment from radiation exposure within the ChEZ; (2) Provide information on remediation guidelines and ecological risk assessment within radioactively contaminated territories based on the results of long-term field monitoring, analytical measurements, and numerical modeling of soils and groundwater radioactive contamination; and (3) Recommend the

  9. Maximum Spectral Luminous Efficacy of White Light

    CERN Document Server

    Murphy, T W

    2013-01-01

    As lighting efficiency improves, it is useful to understand the theoretical limits to luminous efficacy for light that we perceive as white. Independent of the efficiency with which photons are generated, there exists a spectrally-imposed limit to the luminous efficacy of any source of photons. We find that, depending on the acceptable bandpass and---to a lesser extent---the color temperature of the light, the ideal white light source achieves a spectral luminous efficacy of 250--370 lm/W. This is consistent with previous calculations, but here we explore the maximum luminous efficacy as a function of photopic sensitivity threshold, color temperature, and color rendering index; deriving peak performance as a function of all three parameters. We also present example experimental spectra from a variety of light sources, quantifying the intrinsic efficacy of their spectral distributions.

    In 1999, the US Environmental Protection Agency (EPA) published guidelines for product performance testing of skin-applied insect repellents, which provide guidance for topical insect repellent efficacy studies. EPA subsequently uses these sponsor-financed studies in their evaluation of proposed label claims. This paper reviews some of the statistical flaws in the proposed revisions to these guidelines and suggests possible improvements. This review is important because EPA's revisions to the 1999 guidelines do not address these issues.

    Multiple sclerosis is a chronic progressive demyelinating disease affecting over 2.1 million patients worldwide. Patients affected by MS are exposed to an increased risk of infection from communicable diseases, which may lead to severe disease relapses. Studies have analysed the issue of vaccination of MS-affected patients. These studies, however, deal mostly with safety-related issues documenting that most vaccines have been proven to be safe in MS patients and that vaccination is not associated with an increased risk of relapses. By contrast, evidence on the efficacy is comparatively scant and not yet systematised in a comprehensive picture. This aspect is however important, as both MS and its treatment alter the immune responses, a situation that may be associated with a reduced vaccine efficacy. We have now reviewed the literature and assessed the effects of the therapy for MS on vaccine efficacy; we focused on the vaccine against influenza as for the other vaccines the information is still too scant. The majority of drugs appear not associated with a reduced response to vaccination against influenza, with the notable exception of mitoxantrone and glatiramer acetate. For a few drugs, among which natalizumab, information is not sufficiently clear and additional studies are needed to draw a definite conclusion. These results highlight the importance to evaluate the efficacy of vaccination in patients treated with immunosuppressant drugs.

    2016-05-01

    Music therapy is increasingly becoming an intervention used in palliative care settings around the globe. While the specialty of palliative care music therapy is relatively young having emerged in the late 1980s, there is a strong and growing body of evidence demonstrating its efficacy in assisting a variety of issues common at end-of-life. There are multiple music therapy techniques that are implemented with clients in palliative care and they can be categorized in four broad areas: receptive, creative, recreative and combined. These techniques will be presented with respect to their development by clinicians as supported by the descriptive and research literature. Information is also provided on the use of music therapy in facilitating the grieving and bereavement process. Copyright © 2015 Elsevier Ltd. All rights reserved.

  18. Perceived performance of daylighting systems: lighting efficacy and agreeableness

    2002-08-01

    Can daylighting systems be assessed through objective procedures? On one hand, they can be considered as lighting techniques and deserve to be characterised through the same type of parameters: illuminances, uniformity, luminances, colour temperature, colour rendering indices, etc. On the other hand, two major aspects differentiate them from artificial lighting installations. Firstly, the daylight source is variable, requiring a long term approach and an assessment of the duration of the phenomena per day, month or year. Secondly, the brightness of the window cannot be totally disconnected from the content of the view and its agreeableness. This suggests that psychological well-being may be in some cases as important as visual comfort issues. For the window component industry, it appears that a serious concern about the two aspects of windows - i.e. lighting efficacy and agreeableness - should be carefully approached for each design.

    2008-01-01

    Full Text Available Acupuncture has been used to treat a variety of childhood problems; however, the efficacy and safety of pediatric acupuncture remains unclear. This article reviews the existing empirical literature relating to the use of acupuncture for medical conditions in children. A systematic search of the literature revealed that acupuncture has been used to treat five main conditions in children, including pain, nocturnal enuresis, postoperative nausea/vomiting, laryngospasm/stridor, and neurological disorders. Despite a number of methodological issues, including limited sample sizes, lack of randomization, and inappropriate control groups, it is concluded that acupuncture represents a promising intervention for a variety of pediatric health conditions. To further address the safety, effectiveness, and acceptability of acupuncture in children, large-scale randomized controlled trials are needed.

    Two leading nursing organizations, the Greater Kansas City Area Collegiate Nurse Educators and the Kansas City Area Nurse Executives, represent the Kansas City metropolitan area nursing programs and area employers. These two organizations have been engaged in collaborative workforce planning and strategy development around key nursing issues for over 25 years. This model of collaboration is unique in that the partnership is between organizations representing 17 nursing programs and 28 hospitals. The collaborative partnership has enhanced organizational efficiency and efficacy between the groups, which has directly benefited the organizational members. Most importantly, it has had a transformative impact on both nursing education and professional practice in the Kansas City metropolitan area. This article describes the evolution of the partnership and the collaborative work that has led to the accomplishment of mutual goals.

  1. Efficacy of intraoperative neurophysiological monitoring.

    1995-01-01

    Intraoperative neurophysiological monitoring is of benefit in protecting tissue at risk for trauma or ischemia during surgical procedures. Monitoring modalities include EEG, computer processed EEG, somatosensory (SEP), auditory (BAEP), and visual evoked potentials (VEP), and cranial nerve monitoring. The efficacy of monitoring is controversial, because no properly controlled prospective study of outcome with and without monitoring has been done. The weight of evidence suggests that loss of spontaneous EEG and SEP correlate well with critical reductions of cerebral blood flow. Meta-analysis of series comprising 3,028 patients undergoing carotid endarterectomies shows that SEP deteriorated in 5.6% of cases, with 20% of these having postoperative deficits, but more might have had deficits if they had not been shunted. SEP monitoring can be useful in surgery affecting brain and cord vasculature. Monitoring is not indicated for routine lumbosacral spine surgery. BAEPs have predictive value for preservation of hearing after acoustic neuroma surgery, and other surgery near the brainstem. VEPs have been too variable to be of major use in the operating room. For neurophysiologic monitoring to be useful, it must be performed by an experienced team, and the surgeon must be willing to act on the findings. Under these circumstances, monitoring can reduce surgical complications in selected cases.

  10. Issue Mechanism for Embedded Simultaneous Multithreading Processor

    Science.gov (United States)

    Zang, Chengjie; Imai, Shigeki; Frank, Steven; Kimura, Shinji

    Simultaneous Multithreading (SMT) technology enhances instruction throughput by issuing multiple instructions from multiple threads within one clock cycle. For in-order pipeline to each thread, SMT processors can provide large number of issued instructions close to or surpass than using out-of-order pipeline. In this work, we show an efficient issue logic for predicated instruction sequence with the parallel flag in each instruction, where the predicate register based issue control is adopted and the continuous instructions with the parallel flag of ‘0’ are executed in parallel. The flag is pre-defined by a compiler. Instructions from different threads are issued based on the round-robin order. We also introduce an Instruction Queue skip mechanism for thread if the queue is empty. Using this kind of issue logic, we designed a 6 threads, 7-stage, in-order pipeline processor. Based on this processor, we compare round-robin issue policy (RR(T1-Tn)) with other policies: thread one always has the highest priority (PR(T1)) and thread one or thread n has the highest priority in turn (PR(T1-Tn)). The results show that RR(T1-Tn) policy outperforms others and PR(T1-Tn) is almost the same to RR(T1-Tn) from the point of view of the issued instructions per cycle.

    Full Text Available This study aims determining academic self-efficacy perception of teacher candidates. It is survey model. Population of the study consists of teacher candidates in 2010-2011 academic years at Ahmet Keleşoğlu Education Faculty of Education Formation of Selçuk University. A simple random sample was selected as sampling method and the study was conducted on 312 teacher candidates. The data of this study was obtained by “academic selfefficacy scale” which was developed by Jerusalem and Schwazer (1981 and translated into Turkish by Yılmaz, Gürçay, and Ekici (2007 and its reliability value was determined as .79. However, Cronbach Alfa reliability value of this scale became .76 with the result of the data analysis of the study. SPSS package program was used to analyze the data; and the data analysis, frequency, percentage, arithmetic mean, standard deviation, independent samples t-test, one-way analysis of variance (ANOVA and post hoc tests (LSD test were used. When the findings of the research were considered in general, the result showed that the academic self-efficacy perception level of the candidates was at desired level. However, teachers' views about the level of academic self-efficacy perception showed that most of them preferred a lower level option "suits me", instead of "totally suits me" option that was the highest degree of participation of four likert-type scale. This illustrated that their perception about this issue was not at a very high level. When independent variables were taken into account, among the academic perception levels of teacher candidates, a significant difference was detected in terms of working as a teacher or not and academic achievement variables but it revealed no significant difference in terms of gender and type of education program variables.

  20. Target IOP as a measure of glaucoma surgery efficacy

    2015-01-01

    Full Text Available There are numerous criteria of glaucoma surgery efficacy. Among them, IOP level is of special importance. The development of tolerant and target IOP concepts as well as IOP tolerability issue are reviewed below. Individual normal IOP values and their role in glaucoma surgery evaluation are described. The gradation of glaucoma surgery effect and target IOP level depending on optic nerve damage degree as well as statistical principles of scientific data presentation are discussed. Current controversies forced World Glaucoma Association (WGA to develop Guidelines on Design & Reporting Glaucoma Trials (2009 which are now recommended for modern studies. The assessment of appropriate IOP reduction is the keystone of this paper. In addition, the results of the above-mentioned studies were analyzed and own recommendations were developed. Two approaches to evaluate glaucoma surgery efficacy are proposed, i.e., by true IOP (P0 and by IOP decrease from baseline (in %. In the last three decades, novel micro-invasive techniques that prolong glaucoma surgery effect were developed. Among them are suture removal (which can be cut or pulled out, laser suture lysis, Nd:YAG laser goniopuncture following non-penetrating surgery, filtering bleb and sub-scleral space needling revision in the early and late postoperative period. These procedures significantly increased hypotensive effect in the late post-op period (up to 96.7 %. Repeated surgery rate and medical therapy need were the primary surgical outcome while complete and partial success rates were the secondary outcome. Baseline IOP was defined as an IOP level on maximum medical therapy pre-operatively. Medical therapy is an important efficacy criterion as well. The number of drugs used (prostaglandin analogues, beta blockers etc. should be specified. When interpreting surgical outcomes, statistical methods must be considered. The required minimum is Kaplan-Meier survival analysis, scatter diagram, and box

    Stereoscopic medical videos are recorded, e.g., in stereo endoscopy or during video recording medical/dental operations. This paper examines quality issues in the recorded stereoscopic medical videos, as insufficient quality may induce visual fatigue to doctors. No attention has been paid to stereo quality and ensuing fatigue issues in the scientific literature so far. Two of the most commonly encountered quality issues in stereoscopic data, namely stereoscopic window violations and bent windows, were searched for in stereo endoscopic medical videos. Furthermore, an additional stereo quality issue encountered in dental operation videos, namely excessive disparity, was detected and fixed. The conducted experiments prove the existence of such quality issues in stereoscopic medical data and highlight the need for their detection and correction.

    Jackson, K.A.; Hochberg, J.G.; Wilhelmy, S.K.; McClary, J.F.; Christoph, G.G.

    1994-03-01

    This paper discusses management issues associated with the design and implementation of an automated audit analysis system that we use to detect security events. It gives the viewpoint of a team directly responsible for developing and managing such a system. We use Los Alamos National Laboratory`s Network Anomaly Detection and Intrusion Reporter (NADIR) as a case in point. We examine issues encountered at Los Alamos, detail our solutions to them, and where appropriate suggest general solutions. After providing an introduction to NADIR, we explore four general management issues: cost-benefit questions, privacy considerations, legal issues, and system integrity. Our experiences are of general interest both to security professionals and to anyone who may wish to implement a similar system. While NADIR investigates security events, the methods used and the management issues are potentially applicable to a broad range of complex systems. These include those used to audit credit card transactions, medical care payments, and procurement systems.

  6. Leadership, self-efficacy, and student achievement

    Science.gov (United States)

    Grayson, Kristin

    This study examined the relationships between teacher leadership, science teacher self-efficacy, and fifth-grade science student achievement in diverse schools in a San Antonio, Texas, metropolitan school district. Teachers completed a modified version of the Leadership Behavior Description Question (LBDQ) Form XII by Stogdill (1969), the Science Efficacy and Belief Expectations for Science Teaching (SEBEST) by Ritter, Boone, and Rubba (2001, January). Students' scores on the Texas Assessment of Knowledge and Skills (TAKS) measured fifth-grade science achievement. At the teacher level of analysis multiple regressions showed the following relationships between teachers' science self-efficacy and teacher classroom leadership behaviors and the various teacher and school demographic variables. Predictors of teacher self efficacy beliefs included teacher's level of education, gender, and leadership initiating structure. The only significant predictor of teacher self-efficacy outcome expectancy was gender. Higher teacher self-efficacy beliefs predicted higher leadership initiating structure. At the school level of analysis, higher school levels of percentage of students from low socio-economic backgrounds and higher percentage of limited English proficient students predicted lower school student mean science achievement. These findings suggest a need for continued research to clarify relationships between teacher classroom leadership, science teacher self-efficacy, and student achievement especially at the teacher level of analysis. Findings also indicate the importance of developing instructional methods to address student demographics and their needs so that all students, despite their backgrounds, will achieve in science.

    2011-01-01

    We introduce a simple method to explore the efficacy of thermal styling, By using a temperature gradient curling iron we rapidly explore a range of thermal treatment conditions. The thermodynamic literature on the glass transition in keratin fibers explains the surprisingly limited role of elevated temperature in improvements in the efficacy of holding the styled curvature of the fibers. The onset of damage, however, is strongly temperature dependent. This combination of measurements of damage and efficacy shows the range of conditions over which thermal protection products must be functional.

  11. Microbiota Influences Vaccine and Mucosal Adjuvant Efficacy

    Science.gov (United States)

    2017-01-01

    A symbiotic relationship between humans and the microbiota is critical for the maintenance of our health, including development of the immune system, enhancement of the epithelial barrier, and acquisition of nutrients. Recent research has shown that the microbiota impacts immune cell development and differentiation. These findings suggest that the microbiota may also influence adjuvant and vaccine efficacy. Indeed, several factors such as malnutrition and poor sanitation, which affect gut microbiota composition, impair the efficacy of vaccines. Although there is little evidence that microbiota alters vaccine efficacy, further understanding of human immune system-microbiota interactions may lead to the effective development of adjuvants and vaccines for the treatment of diseases.

    In this study, polyaminopropyl biguanide (PAPB) was compared to the molecularly closely related polyhexamethylene biguanide (PHMB) with respect to chemical relationship, antiseptic efficacy and cytotoxicity in vitro. Cytotoxicity for human keratinocytes (HaCaTs) and murine fibroblasts (L929) was determined according to ISO EN 10993-5 for both substances. Antimicrobial efficacy tests were performed via determination of the MBC, quantitative suspension method for substances and investigation of two PAPB- or PHMB-containing dressings against Staphyloccoccus aureus, Escherichia coli and Pseudomonas aeruginosa, according to international standards. Prior mass spectrometry was performed for chemical differentiation of the investigated substances. PHMB showed high toxicity even in low concentrations for both tested cell lines and a high antimicrobial efficacy against S. aureus and E. coli. In the case of PAPB, no or only low cytotoxicity was detected after 72 h, whilst comparable antibacterial features are lacking, as PAPB showed no relevant antimicrobial effects. Even though chemically closely related, PAPB proved to be ineffective in bacterial eradication, whilst PHMB showed a high efficacy. The discovery and establishment of safe and effective alternative antiseptics are important issues for the treatment of infected wounds. In particular, rising bacterial resistances to established agents, as well as ongoing discussions of potential toxic or carcinogenic effects emphasize this necessity. Nevertheless, the presented results highlight that even small changes in the chemical structure of related agents such as PHMB and PAPB can dramatically affect their efficacy and, therefore, need to be carefully distinguished and assessed side by side.

    Full Text Available The concept of self-efficacy is presented in the paper, which has not been applied yet in empirical psychological research in Slovenia, and selected metric characteristics of the translated and adapted Schwarzer's generalised self-efficacy scale (LSU are analysed. The introduction focuses on self-efficacy within organisational context, the self-efficacy versus self-esteem issue and the Bandura's socio-cognitive paradigm. The psychometric analyses are based on a sample of 120 undergraduates, supplemented by comparisons with a sample of 15 employees. In addition to the LSU, a self-regulation scale was applied (another adaptation to Slovenian, a standard trait-anxiety scale and a self-confidence scale. The self-efficacy scale is analysed in detail – including the item level, while the other three instruments are only addressed on the scale level. LSU's reliability in terms of internal consistency proved to be sufficient (Cronbach α 0,77 for the students and 0,87 for the employees. Concurrent validity was verified through indicator convergence (a high positive correlation with the two related scales and a high negative correlation with the anxiety scale. Another piece of evidence in favour of construct validity of the LSU is provided by lack of significant differences between distinct groups of students on any of the scales, as well as by significant differences between the students and the employees on all the four scales.

    Objective The management of cervical intraepithelial neoplasia (CIN) and early invasive cancer of the uterine cervix is very difficult to approach, especially in case of young woman who wants to preserve her fertility. Conization of the cervix may have various kinds of disadvantage. The objective of this clinical retrospective study is to investigate the therapeutic effects and clinical efficacy of photodynamic therapy (PDT) including combined chemo-photodynamic therapy in patients with pre-malignant CIN and malignant invasive cervical cancer. Methods Total number of PDT trial case was 50 cases and total number of patient was 22 patients who registered to PDT clinic. We used photogem sensitizer and 632 nm diode laser in early two cases. After then we performed PDT using photofrin sensitizer and 630 nm diode laser in other cases. We used flat-cut, microlens, cylindrical diffuser, and interstitial type optic fibers in order to irradiate the lesions. 240 J/cm2 energy was irradiated to the lesions. Results CIN 2 were 4 cases (18.2%) and CIN 3 were 15 (68.2%) and invasive cervical cancer were 3 (13.6%). Complete remission (CR) was found in 20 patients (91%). One case of 19 patients with CIN lesion recurred at 18 months after PDT treatment. CR was found in 18 cases in the patients with CIN lesions (95%). CR was found in 2 cases in the patients with invasive cervical cancer (67%). Conclusion Our data showed that CR rate was fantastic in CIN group (95%). This study suggests that PDT can be recommended as new optimistic management modality on the patients with pre-malignant CIN lesions including carcinoma in situ and relatively early invasive cancer of the uterine cervix. Combined chemo-photodynamic therapy is essential in case of invasive cervical cancer. For the young age group who desperately want to preserve their fertility and have a healthy baby, PDT can be a beacon of hope. PMID:27896250

    Personal and professional experiences influence teachers' perceptions of their ability to implement environmental science curricula and to positively impact students' learning. The purpose of this study was twofold: to determine what influence, if any, an intensive field-based life science course and service learning had on preservice teachers' self-efficacy for teaching about the environment and to determine which aspects of the combined field-based course/service learning preservice teachers perceived as effective for enhancing their self-efficacy. Data were collected from class documents and written teaching reflections of 38 middle-level preservice teachers. Some participants ( n = 18) also completed the Environmental Education Efficacy Belief Instrument at the beginning and end of the semester. Both qualitative and quantitative data analyses indicated a significant increase in PSTs' personal efficacies for environmental teaching, t(17) = 4.50, p = .000, d = 1.30, 95 % CI (.33, .90), but not outcome expectancy, t(17) = 1.15, p = .268, d = .220, 95 % CI (-.06, .20). Preservice teachers reported three aspects of the course as important for enhancing their self-efficacies: learning about ecological concepts through place-based issues, service learning with K-5 students and EE curriculum development. Data from this study extend prior work by indicating that practical experiences with students were not the sole factor in shaping PSTs' self-efficacy; learning ecological concepts and theories in field-based activities grounded in the local landscape also influenced PSTs' self-efficacy.

  17. Status of safety issues at licensed power plants: TMI Action Plan requirements; unresolved safety issues; generic safety issues; other multiplant action issues. Supplement 3

    As part of ongoing US Nuclear Regulatory Commission (NRC) efforts to ensure the quality and accountability of safety issue information, the NRC established a program for publishing an annual report on the status of licensee implementation and NRC verification of safety issues in major NRC requirements areas. This information was initially compiled and reported in three NUREG-series volumes. Volume 1, published in March 1991, addressed the status of Three Mile Island (TMI) Action Plan Requirements. Volume 2, published in May 1991, addressed the status of unresolved safety issues (USIs). Volume 3, published in June 1991, addressed the implementation and verification status of generic safety issues (GSIs). The first annual supplement, which combined these volumes into a single report and presented updated information as of September 30, 1991, was published in December 1991. The second annual supplement, which provided updated information as of September 30, 1992, was published in December 1992. Supplement 2 also provided the status of licensee implementation and NRC verification of other multiplant action (MPA) issues not related to TMI Action Plan requirements, USIs, or GSIs. This third annual NUREG report, Supplement 3, presents updated information as of September 30, 1993. This report gives a comprehensive description of the implementation and verification status of TMI Action Plan requirements, safety issues designated as USIs, GSIs, and other MPAs that have been resolved and involve implementation of an action or actions by licensees. This report makes the information available to other interested parties, including the public. Additionally, this report serves as a follow-on to NUREG-0933, ``A Prioritization of Generic Safety Issues,`` which tracks safety issues until requirements are approved for imposition at licensed plants or until the NRC issues a request for action by licensees.

    The aim of this study was to develop a formal substantive theory (FST) on the multidimensional behavioral process of coping with health issues. Intacting integrity while coping with health issues emerged as the core category of this FST. People facing health issues strive to safeguard and keep...... intact their integrity not only on an individual level but also as members of a group or a system. This intacting process is executed by attunement, continuously minimizing the discrepancy between personal values, personal health, self-expectations and external conditions as health- and cultural...
