    Effect of Cog Threads under Rat Skin

    DERMATOLOGIC SURGERY, Issue 12 2005
    Hyo Jook Jang MD
    Background. The aging face loses the tensile strength of structural integrity. Cog threads have been used recently to tighten lax skin and soft tissue. Objective. A comparative study of the effects of cog, monofilament, and multifilament threads under rat skin. Methods. Each cog, monofilament, and multifilament thread was inserted under the facial skin of a cadaver and the panniculus carnosus of rat dorsal skin. The maximum holding strength (MHS) of the thread and the tearing strength of the skin around the thread were measured with a tensiometer. The thickness of the capsule around the thread and the myofibroblasts was observed histologically. Results. In the cadaver, the MHS of the cog thread was 190.7 ± 65.6 g. It was greater than that of the monofilament (22.4 ± 7.7 g) or multifilament (40.4 ± 19.7 g) thread. In the rat, the MHS of the cog thread was 95.1 ± 18.8 g. It was greater than that of the monofilament (4.3 ± 1.3 g) or multifilament (10.9 ± 2.1 g) thread in the second week. The thickness of the capsule around the cog thread was 93.0 ± 3.2 ,m. It was thicker than the monofilament thread's capsule, 39.2 ± 12.1 ,m, in the fourth week. The number of myofibroblasts presented significantly more in the cog (96.0 ± 72.4) than in the monofilament thread (4.3 ± 4.4). The rumpled in-between skin suspended by each of the three different threads returned to its original state in 2 weeks. Conclusion. The cog thread placed under the rat skin immediately pulled the skin and subcutaneous tissue. The myofibroblasts around the thread played a role in fibrous tissue contracture 4 weeks postinsertion of the thread. These findings could be the basis for clinical application.

    European Schoolnet: enabling school networking

    EUROPEAN JOURNAL OF EDUCATION, Issue 4 2009
    SANTI SCIMECA
    School networking is increasingly important in a globalised world, where schools themselves can be actors on an international stage. This article builds on the activities and experience of the longest established European initiative in this area, European Schoolnet (EUN), a network of 31 Ministries of Education. First, we offer an introduction covering school networks. We then describe the case of European Schoolnet, its history, role, and relationship with other school networks in the world. We then describe the underlying structure of EUN school networks and their basic characteristics. Using these basic characteristics as a framework, we consider a number of eTwinning, European Schoolnet networks: Network of Innovative Schools (ENIS) and myEUROPE. Last, we identify key features of network literacy, potential future trends in school networks, and areas where further research is needed in this field, and offer some recommendations. [source]


    Access to essential drugs in Guyana: a public health challenge,,

    INTERNATIONAL JOURNAL OF HEALTH PLANNING AND MANAGEMENT, Issue 1 2010
    Enrique Seoane-Vazquez
    Abstract Guyana's pharmaceutical sector faces major challenges that limit access to essential drugs. This study analyzes Guyana's drug policy and regulation, public financing, and drug procurement and delivery. The study also identifies main barriers to drug access and proposes alternatives to strengthen the country's public health functions. Data were collected from the country's regulatory agencies, public procurement agency, pharmacies, wholesalers, and pharmaceutical companies. The information was supplemented with interviews with a convenient sample of Guyanese health authorities and stakeholders. Data were also compiled from scientific databases, and web pages of the country's Ministries of Health, Commerce and Finance, the Bureau of Statistics, and international organizations. Major barriers to drug access include: (1) lack of national drug policy and regulation, and limited role of the regulatory authority; (2) inefficient drug selection and irrational drug use; (3) insufficient financial resources and lack of drug pricing policy; (4) inefficient planning and managing public supply system; (5) deficient epidemiological and information systems; and (6) inadequate infrastructures and human resources shortage. Improving drug access in Guyana requires the strengthening of the country's public health functions and the implementation of a national drug policy and pricing policy, streamlining the drug financing, procurement, and planning and managing drug supply; and adequate infrastructures and human resources.

    Old Testament and Church Ministries in Two Ecumenical Dialogues

    INTERNATIONAL JOURNAL OF SYSTEMATIC THEOLOGY, Issue 3 2004
    Joseph G. Mueller
    A sample of the work of recent ecumenical dialogues (BEM and the international Lutheran, Roman Catholic document on church and justification) shows that their discussions of church institutions have failed to do this adequately. This failure has complicated the efforts at unity to which these dialogues intend to contribute. Attention to the Old Testament roots of church institutions can help ecumenical ecclesiology to focus better on some important issues. [source]


    Radio Ministries: Religion on Australian Commercial Radio from the 1920s to the 1960s,

    JOURNAL OF RELIGIOUS HISTORY, Issue 1 2008
    BRIDGET GRIFFEN-FOLEY
    This article examines the first forty years of religious broadcasting on commercial radio in Australia, a subject largely neglected by historians of Australian religion and the media. It reveals the diversity of religious broadcasting on Australian commercial radio, the ambiguities of the regulatory framework within which it operated, the influence of American religious broadcasting in Australia, and the challenges confronting religious broadcasters, particularly in the decade between the introduction of television and the emergence of talkback radio. The article concludes in the second half of the 1960s, when religious programming faced mounting commercial pressures, as well as a new opportunity in the shape of "talkback" radio. [source]


    Endocrine disruptor issues in Japan

    CONGENITAL ANOMALIES, Issue 2 2002
    Taisen Iguchi
    ABSTRACT, Monitoring of environmental chemicals in Japan has revealed that several endocrine active chemicals are in river water, sediments, and wildlife as well as in the human umbilical cord. In 2001, risk assessments of tributyltin and nonylphenol have been conducted by the Ministry of the Environment, Japan. Risk assessments of di(2-ethylhexyl)phthalate and di-isononyl phthalate have also been performed by the Ministry of Health, Labour and Welfare using a toxicological point of view in 2001. In this review, an overview of recent progress in endocrine disruptor research in Japan will be provided. [source]

    When business associations and a federal ministry jointly consult civil society: a CSR policy case study on the development of the CSR Austria Guiding Vision

    CORPORATE SOCIAL RESPONSIBILITY AND ENVIRONMENTAL MANAGEMENT, Issue 5 2008
    Astrid Konrad
    Abstract In 2002, Austrian business organizations and the Austrian Federal Ministry of Economics and Labour decided to raise the awareness of CSR in Austria by formulating a CSR guiding vision for Austrian businesses after consulting a broad variety of stakeholders. This paper describes the development of the ,CSR Austria Guiding Vision' from 2003, and it gives a brief overview of other public CSR initiatives launched in Austria since then. Since the authors were involved drafting the CSR Austria Guiding Vision as consultants, the paper describes success factors, lessons learned and recommendations relevant for other large-scale stakeholder dialogues on CSR from an insider perspective. Overall, we conclude that a clear idea about the structure, the type and the rules of the stakeholder involvement (conceptual issues), in combination with a timely, honest and empathic approach towards stakeholders (procedural issues), are important success factors for any stakeholder dialogue.

    Are psychiatrists affecting the legal process by answering legal questions?

    CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 2 2008
    Timothy Hardie
    Background,Psychiatrists are often asked to answer legal questions. The extent to which they answer strictly legal rather than medical matters is not known. Aim,To investigate how strongly psychiatrists in England and Wales express opinions on one legal question , that of diminished responsibility in respect of a murder charge, and how this is related to outcome in court. Method,Our data were extracted from psychiatric reports and case files supplied by the then Department of Constitutional Affairs (now the Ministry of Justice) on cases heard in the Crown Courts between 1 January 1997 and 31 December 2001 in which the defence of diminished responsibility had been raised. The cases had been selected by the Law Commission in their earlier review of partial defences to murder. We devised a reliable system of rating the presence/absence and strength of expression of a legal opinion in the medical reports. We tested the data for relationship between nature and strength of opinion and progression to trial and verdict. Results,Psychiatric reports were available on 143 of 156 cases in which diminished responsibility was considered. They yielded 338 opinions on at least one aspect of diminished responsibility. In 110 (93%) of the 118 cases in which there was a diminished verdict, this was made without trial and, therefore, without reference to a jury. In only eight (27%) out of the 30 cases that went to trial, was a diminished responsibility verdict made. Half of the reports (169) gave a clear opinion on diminished responsibility, a third (121) invited the court to draw a particular conclusion and only 11% (36) provided relevant evidence without answering the legal questions. When there was an opinion or an invitation to make a finding on the legal question, a trial was less likely. A trial was also less likely if reports agreed on what the verdict should be. Conclusions,Psychiatrists frequently answer the legal question of diminished responsibility. The judiciary and medical experts should join in research to examine the consequences of different styles or approaches in presentation of essentially similar evidence in court.

    Education and Social Change: The Case of Israel's State Curriculum

    CURRICULUM INQUIRY, Issue 4 2007
    AMOS HOFMAN
    ABSTRACT The aim of this article is to explore, through the case of the official Israeli state curriculum, how the educational system is affected by social changes and how it responds to them, and to suggest curricular directions that go along with the new social reality that has emerged in Israel during the past decade. We offer a conceptual-theoretical analysis based on the examination of 10 subject areas taught at Israeli schools by leading experts who investigated the curriculum documents of the Ministry of Education in their disciplines. We identify three stages of curriculum development in Israel since its establishment: promotion of hegemonic national goals, emphasis on academic structure of knowledge, and in recent decades, multiple conflicting goals. Changes in the Israeli state curricula indeed reflect a response to broader social changes, yet these changes are partial, irresolute, and scattered. There is a need for a transcultural approach, promoting a core curriculum common to all groups in Israel, beyond which each group may express its uniqueness. [source]


    A Development Delivery Institution for the Tribal Communities: Experience of the National Rural Employment Guarantee Scheme in India

    DEVELOPMENT POLICY REVIEW, Issue 4 2010
    Pulak Mishra
    This article examines the varied impacts of the National Rural Employment Guarantee Scheme (NREGS) as a development delivery institution for the tribal communities vis-à-vis other social groups across the Indian States, using the framework of new institutional economics. A number of State-specific, socio-economic institutional factors seem to be responsible for these variations. The article therefore suggests institutional reforms and convergence of the development initiatives of the Ministry of Tribal Affairs with the NREGS in order to realise the optimal potential of the scheme, and, in particular, to ensure greater livelihood opportunities for these marginalised groups and their entitlement to productive resources with greater socio-economic and political empowerment.

    Simultaneous Chlamydia trachomatis and HPV infection in pregnant women

    DIAGNOSTIC CYTOPATHOLOGY, Issue 6 2010
    Sônia Maria Miranda Pereira B.Sc.
    Pregnancy is associated with HPV infection and with Chlamydia trachomatis (CT) infection mostly due to the natural immunosuppression. In addition, pregnancy associated to CT infection can lead to adverse conditions to the woman and fetus, and CT is also believed to be a co-factor in human immunodeficiency virus infection and HPV-induced cervical cancer. The aim of this study was to establish the odds ratios (OR) of CT infection in to HPV-infected pregnant women and vice versa of women stratified by age (<25 years) and marital status. This work is part of a national multicentric transversal study carried out in six Brazilian cities supported by the Ministry of Health of Federal Government of Brazil in 2003. Cervical scrapes of 371 pregnant women were sampled. We performed a hybrid capture-2 technique to diagnose these samples on HPV and CT infection, and the women responded a questionnaire. Significant association was observed between nonstable marital status and hr-HPV infection [OR = 2.61 (1.38,4.97) P = 0.003)], and age <25 years old [OR = 2.26 (1.09,4.71) P = 0.029]. Nonstable marital status was also associated with lr-HPV infection [OR = 2.67 (1.59,4.50) P < 0.001), and age <25 years old [OR = 2.55 (1.51,4.32) P < 0.001). Fifty of the 371 pregnant women were infected with hr-HPV (13.5%) and 111 (30.0%) were infected with lr-HPV. The coinfections of HPV and CT were found in 31 women, that is, 8.36% of the pregnant women (P < 0.001). The high rate of simultaneous CT and HPV infection in pregnant women favors the recommendation to screen pregnant women for both CT and HPV. Diagn. Cytopathol. 2010. © 2009 Wiley-Liss, Inc.

    A Stark Examination of Prison Culture and Prison Ministry

    DIALOG, Issue 3 2008
    R.N. Ristad
    Abstract:, This article offers an insightful examination of prison ministry from the inside, from someone who has been involved with this ministry for over forty-five years. The author discusses four major issues that are particularly costly, both in terms of personal human costs and also financial costs. First, society's misconceptions about prison violence, and the complex, varied ways prisoners experience violence. Second, the false sense of security the current practices of institutionalization create, and the consequences they have on the inmates. Third, the risk factors that can predispose children to ending up in prison, and the lack of care and attention those children often receive. And fourth, the way in which the criminalization of drug abuse has exacerbated many problems with the current prison system. The author concludes his article with some suggestions for reforming the prison system. [source]

    Confirmation Ministry in the Batak Church

    DIALOG, Issue 3 2002
    Binsar Nainggolan
    Historically, confirmation ministry among Batak's took the form of missionaries presenting the Christian religion in an apologetic and persuasive tone, in an effort to ready Batak converts for Baptism. Today, confirmation ministry among Batak Christians is understood as a fleshing out of what it means to be baptized into the church community. This article explores the method and aims of the confirmation rite and ministry among Batak Christians. [source]


    Addiction Research Centres and the Nurturing of Creativity The Chinese National Institute on Drug Dependence, Peking University: past, present and future

    ADDICTION, Issue 9 2010
    Xi Wang
    ABSTRACT In the 25 years since drug abuse re-emerged in China in the 1980s, the National Institute of Drug Dependence (NIDD) has made many contributions to China's antidrug campaign. This present paper offers an account of the history, current status and future of drug dependence research at NIDD. NIDD was originally a research centre at Beijing Medical University, founded by the Chinese Ministry of Health to address the rapid spread of drug abuse in China. Originally, the main task of NIDD was to complete the commissions assigned by the government and university. Further developments transformed NIDD into a national research institute in the field of drug addiction that began to conduct its own research. NIDD has now created a professional team spread across several independent departments involved in neurobiological mechanisms, epidemiological surveys and monitoring, pre-clinical and clinical evaluation of new drugs (mainly analgesic drugs and detoxification drugs) and informatics and data analysis. As a university-based research institute, NIDD's funding derives mainly from grants provided by the government and financial support from international organizations. Its past and present research has a gained NIDD a reputation with both practitioners and policy makers in the field of drug addiction. In the future, NIDD will continue to engage in various aspects of drug addiction research and will enter the field of brain function. [source]


    Landscape composition and vole outbreaks: evidence from an eight year study of Arvicola terrestris

    ECOGRAPHY, Issue 6 2000
    E. Fichet-Calvet
    This study investigates the relationships between landscape composition and the population dynamics of the fossorial water vole Arvicola terrestris. Land use patterns were studied based on agricultural and forestry data from the French Ministry of Agriculture collected in 1955 and 1988. In the Massif Central, France, water vole populations were monitored from 1985 to 1993 by using index methods. Outbreaks of water vole populations occurred in many dispersed epicentres and spread suddenly and widely over > 7500 km2. At a regional scale, the fluctuation lasts six years on average with an outbreak period lasting from two to three years. Density variation patterns are positively correlated with the proportion of permanent grassland to agricultural land. A high risk of outbreak is linked to a high proportion of permanent grassland (over 90%), whereas a low risk of outbreak is linked to a proportion of < 80%, Conversely, density variation patterns are negatively correlated with the proportion of temporary grassland to agricultural land and with the proportion of forest to total land in the western (major) part of the study area. Temporary grassland thus appears to be a marginal habitat for water voles and extensive forests could act as a brake on outbreaks. The increase in the area of permanent grassland from 1955 to 1988 was apparently the major cause of chronic high densities of water voles. Therefore, land use and landscape management could be one way to control water vole outbreaks. [source]


    Three-year mortality and predictors after release: a longitudinal study of the first-time drug offenders in Taiwan

    ADDICTION, Issue 5 2010
    Chuan-Yu Chen
    ABSTRACT Aims To assess the possible increase in mortality rate and associated socio-demographic and judiciary determinants among first-time drug offenders during the first 3 years after release from correctional facilities. Setting and participants A total of 22 224 male and 4444 female adults who had served a sentence of at least 1 day in correctional facilities for illegal drug-related offences were identified from the judiciary records of the Ministry of Justice, Taiwan. Design and measurements The underlying causes of death were defined by the International Classification of Diseases, ninth revision. Findings All-cause standardized mortality ratios (SMR) were 7 for schedule I (e.g. heroin) and 3 for schedule II (e.g. methamphetamine) drug offenders, respectively; accidents, suicide and circulatory diseases were three leading causes of death. After release, the risk of death among those drug offenders without subsequent incarceration increased gradually until the 9th month. Those who were aged 30 years or older, had an engagement with a higher-ranked schedule substance or who received severe sentences were two to three times more likely to die. Substantial reduction in the risk of death was linked with re-imprisonment. Conclusions The SMR estimates for external causes were greater than those for disease-related causes in drug offenders, and schedule I drugs-related mortality rate was twice as high as that with schedule II drugs. In transitioning from the correctional setting to the community, the health needs of drug offenders should be addressed by the provision of continuous, adequate medical care tailored to individual background, medical history and drug experience.

    Addiction research centres and the nurturing of creativity: Centre for Social Research on Alcohol and Drugs (SoRAD), Stockholm University, Sweden

    ADDICTION, Issue 3 2010
    Kerstin Stenius
    ABSTRACT The Centre for Social Research on Alcohol and Drugs (SoRAD) was established as a national research centre and department within the Faculty of Social Science at Stockholm University in 1997, following a Government Report and with the aim to strengthen social alcohol and drug research. Initially, core funding came from the Swedish Council for Working Life and Social Research and from the Ministry of Health and Social Affairs for several long-term projects. Today, SoRAD, with 25 senior and junior researchers, has core funding from the university but most of its funding comes from external national and international grants. Research is organized under three themes: consumption, problems and norms, alcohol and drug policy and societal reactions, treatment and recovery processes. SoRADs scientific approach, multi-disciplinarity, a mix of qualitative and quantitative methods and international comparisons was established by the centre's first leader, Robin Room. Regular internal seminars are held and young researchers are encouraged to attend scientific meetings and take part in collaborative projects. SoRAD researchers produce government-funded monthly statistics on alcohol consumption and purchase, and take part in various national government committees, but SoRADs research has no clear political or bureaucratic constraints. One of the future challenges for SoRAD will be the proposed system for university grants allocation, where applied social science will have difficulties competing with basic biomedical research if decisions are based on publication and citation measures.

    International comparison test in Asia-Pacific region for impulse voltage measurements

    ELECTRICAL ENGINEERING IN JAPAN, Issue 3 2009
    Takayuki Wakimoto
    Abstract The national standard class divider for the lightning impulse voltage measurements in Japan was developed in 1998. After three years, the standard impulse voltage calibrator has also been manufactured. These standard equipment are used as an industrial standard, and the performance had been evaluated annually supported by the Ministry of Economy, Trade and Industry (METI). The standard impulse measuring system including the standard divider participated in the worldwide comparison test and its good performance was confirmed in 1999. Another international comparison test was carried out among three countries in the Asia-Pacific region in 2004 again and the standard measuring system participated in the test. In this paper, the details and the results of the international comparison tests in 2004 are described. © 2008 Wiley Periodicals, Inc.

    Were volatile organic compounds the inducing factors for subjective symptoms of employees working in newly constructed hospitals?

    ENVIRONMENTAL TOXICOLOGY, Issue 4 2004
    Tomoko Takigawa
    Abstract This study demonstrated possible relationships between environmental, personal, and occupational factors and changes in the subjective health symptoms of 214 employees after the relocation of a hospital in a region of Japan. Eight indoor volatile organic compounds (VOCs) were detected in at least one of the 19 rooms investigated, and total VOC (TVOC) concentrations in 8 rooms exceeded the advisable value (400 ,g/m3) established by the Ministry of Health, Labour and Welfare of Japan. Formaldehyde was detected in all the investigated rooms, but none of the results exceeded the guideline value (100 ,g/m3). Multiple logistic regression analysis was applied to select variables significantly associated with the subjective symptoms that can be induced by sick building syndrome. The results showed that subjective symptoms of deterioration in the skin, eye, ear, throat, chest, central nervous system, autonomic system, musculoskeletal system, and digestive system among employees were associated mainly with gender difference and high TVOC concentrations (>1200 ,g/m3). Long work hours (>50 h per week) in females and smoking in males were to be blamed for the deterioration of their symptoms. The present findings suggest that to protect employees from indoor environment-related adverse health effects, it is necessary to reduce the concentration of indoor chemicals in new buildings, to decrease work hours, and to forbid smoking. © 2004 Wiley Periodicals, Inc.

    A new biodegradation prediction model specific to petroleum hydrocarbons

    ENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 8 2005
    Philip Howard
    Abstract A new predictive model for determining quantitative primary biodegradation half-lives of individual petroleum hydrocarbons has been developed. This model uses a fragment-based approach similar to that of several other biodegradation models, such as those within the Biodegradation Probability Program (BIOWIN) estimation program. In the present study, a half-life in days is estimated using multiple linear regression against counts of 31 distinct molecular fragments. The model was developed using a data set consisting of 175 compounds with environmentally relevant experimental data that was divided into training and validation sets. The original fragments from the Ministry of International Trade and Industry BIOWIN model were used initially as structural descriptors and additional fragments were then added to better describe the ring systems found in petroleum hydrocarbons and to adjust for nonlinearity within the experimental data. The training and validation sets had r2 values of 0.91 and 0.81, respectively. [source]


    Using BiowinÔ, Bayes, and batteries to predict ready biodegradability

    ENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 4 2004
    Robert S. Boethling
    Abstract Wether or not a given chemical substance is readily biodegradable is an important piece of information in risk screening for both new and existing chemicals. Despite the relatively low cost of Organization for Economic Cooperation and Development tests, data are often unavailable and biodegradability must be estimated. In this paper, we focus on the predictive value of selected BiowinÔ models and model batteries using Bayesian analysis. Posterior probabilities, calculated based on performance with the model training sets using Bayes' theorem, were closely matched by actual performance with an expanded set of 374 premanufacture notice (PMN) substances. Further analysis suggested that a simple battery consisting of Biowin3 (survey ultimate biodegradation model) and Biowin5 (Ministry of International Trade and Industry [MITI] linear model) would have enhanced predictive power in comparison to individual models. Application of the battery to PMN substances showed that performance matched expectation. This approach significantly reduced both false positives for ready biodegradability and the overall misclassification rate. Similar results were obtained for a set of 63 pharmaceuticals using a battery consisting of Biowin3 and Biowin6 (MITI nonlinear model). Biodegradation data for PMNs tested in multiple ready tests or both inherent and ready biodegradation tests yielded additional insights that may be useful in risk screening. [source]


    A cautionary note on the use of species presence and absence data in deriving sediment criteria

    ENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 2 2002
    Katherine Von Stackelberg
    Abstract In recent years, a variety of approaches to deriving sediment quality guidelines have been developed. One approach relies on establishing an empirical relationship between the concentration of a contaminant in sediment and the condition of some biological indicator, for example, combining measured sediment concentrations of contaminants combined with data on colocated benthic species to measure in situ community effects of contamination. Biological threshold concentrations derived in this manner are being considered or have already been adopted by some regulatory agencies as a means for deriving sediment guidelines (e.g., Canada's Provincial Sediment Quality Guidelines). In order to test the validity of this method, we constructed several Monte Carlo simulations to illustrate that the methodology used to develop these guidelines is flawed by the effects of sampling and statistical artifacts that emerge from undersampling a lognormal density function. As a case study, this paper will present the screening level concentration method used by the Ontario Ministry of the Environment (Toronto, ON, Canada) and provide the results of several probabilistic exercises highlighting these issues. We present a word of caution on the applicability of methods that rely exclusively on statistical and mathematical relationships between invertebrate data and sediment concentrations to derive sediment quality guidelines.

    Predicting ready biodegradability in the Japanese ministry of international trade and industry test

    ENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 10 2000
    Jay Tunkel
    Abstract Two new predictive models for assessing a chemical's biodegradability in the Japanese Ministry of International Trade and Industry (MITI) ready biodegradation test have been developed. The new methods use an approach similar to that in the existing BIOWIN© program, in which the probability of rapid biodegradation is estimated by means of multiple linear or nonlinear regression against counts of 36 chemical substructures (molecular fragments) plus molecular weight (mol wt). The data set used to develop the new models consisted of results (pass/no pass) from the MITI test for 884 discrete organic chemicals. This data set was first divided into randomly selected training and validation sets, and new coefficients were derived for the training set using the BIOWIN fragment library and mol wt as independent variables. Based on these results, the fragment library was then modified by deleting some fragments and adding or refining others, and the new set of independent variables (42 substructures and mol wt) was fit to the MITI data. The resulting linear and nonlinear regression models accurately classified 81% of the chemicals in an independent validation set. Like the established BIOWIN models, the MITI models are intended for use in chemical screening and in setting priorities for further review. [source]


    A compound Poisson model for the annual area burned by forest fires in the province of Ontario

    ENVIRONMETRICS, Issue 5 2010
    Justin J. Podur
    Abstract We use the compound Poisson probability distribution to model the annual area burned by forest fires in the Canadian province of Ontario. Models for sums-of-random variables, relevant for modeling aggregate insurance claims and assessing insurance risk are also relevant in modeling aggregate area burned based on sums of sizes of individual fires. Researchers have fit the distribution of fire sizes to the truncated power-law (or Pareto) distribution (Ward et al., 2001) and a four-parameter Weibull distribution (Reed and McKelvey, 2002). Armstrong (1999) fitted a lognormal distribution to annual proportion of area burned by forest fires in a region of Alberta. We derive expressions and moments for aggregate area burned in Ontario using fire data from the Ontario Ministry of Natural Resources (OMNR). We derive expressions for the distribution of area burned for "severe" and "mild" fire weather scenarios and for "intensive suppression" and "no suppression" scenarios (represented by the intensive and extensive fire protection zones of the province). These distributions can be used to perform risk analysis of annual area burned. Copyright © 2009 John Wiley & Sons, Ltd. [source]


    PCA- and PMF-based methodology for air pollution sources identification and apportionment

    ENVIRONMETRICS, Issue 8 2009
    Marie Chavent
    Abstract Air pollution is a wide concern for human health and requires the development of air quality control strategies. In order to achieve this goal pollution sources have to be accurately identified and quantified. The case study presented in this paper is part of a scientific project initiated by the French Ministry of Ecology and Sustainable Development. For the following study measurements of chemical composition data for particles have been conducted on a French urban site. The first step of the study consists in the identification of the sources profiles which is achieved through principal component analysis (PCA) completed by a rotation technique. Then the apportionment of the sources is evaluated with a receptor modeling using positive matrix factorization (PMF) as estimation method. Finally the joint use of these two statistical methods enables to characterize and apportion five different sources of fine particulate emission. Copyright © 2008 John Wiley & Sons, Ltd. [source]

Methods: This study, supported by a rcse;lrch grant from the Ministry of Health and Wellare of Japan, is part of a research project on the clinical presentation and pathogcnesis of brain dysgenesis. Questionnaires regarding the type of CD, family and pact historics, clinical signs and symptoms and their severity were distributed to I200 institutions comprising child neurologists or pediatricians. CDs werc classified into following 6 types; lissencephaly (agyria-pachygyria spcctrum), cobblestone lissencephaly, polymicrogyria including schizencephaly and hilateral perisylvian syndrome, diffuse heterotopia, focal heterotopia, and hemiinegalencephaly. All patients who had been diagnoscd as CD either by MRI, CT, autopsy or histological cxamination at or after surgical treatment wcre included. Diagnosis of CD by CT or MRI was mainly made by a radiologist, child neurologist, or pediatrician. Double classification was corrected. Epilepsy was classified according to criteria of the ILEA. Seizure frcquencies wcre recorded. Results: A total or 676 cases from 328 institutions was availablc, and distributed as follows: 277 of lissencephaly, I48 of cobblestone lissencephaly (10 cases of Walkcr-Warburg syndrome and 138 Fukuyaina type congcnital muscular dystrophy), I30 of polymicrogyria, 40 of diffuse heterotopia (24 subcortical band hetcrotopia and I6 perivcntricular nodular hcterotopia), 37 of focal heterotopia, and 44 of hemimegalencephaly. In 130 cases of polymicrogyria, 13 cases of bilatcral perisylvian syndrome, and 38 cases of schizencephaly were includcd. Of 667 cases available for study, 500 (75.0%) had epilepsy in which generalized epilepsy including West and Lcnnox syndromes comprised 54.1 % and localization-related epilepsies comprised 46.7%. Thc frequency of seizures could be ascertained in 455 cases, of which 36.0% had daily seizures, and I I .4%) had more than onc seizure per week. The incidencc of epilepsy in cach type of CD was as follows: 86% inlissencephaly, 50% in cobblestone lissencephaly (patients with WalkcrWarburg syndrome had epilepsy in 90%, whercas those with Fukuyama type congenital muscular dystrophy had epilepsy in 46.7%), 71.3% in polymicrogyria, 77.5% in diffusc hetcrotopia (9 1.7% in subcortical band heterotopia and 56.2% in periventricular nodular heterotopia), 74.3% in focal heterotopia, and 93.2% in hemimegalcncephaly. Conclusion: As recent investigations have reported, this study confirmed the high incidence of intractable cpilepsy in CDs. Epilepsy was more prevalcnt in cases with subcortical heterotopia than i n cascs with periventricular nodular helcrotopia. Thc incidcnce or epilepsy was also higher in the focal hcterotopias located subcortically than those dccper in white matter or in the periventricular region. Thcse differences in incidence of epilepsy depending on the location of hcterotopia may give somc clues to the nature of epileptogenesis in CD. [source]


    Sitting in Silence: Self, Emotion, and Tradition in the Genesis of a Charismatic Ministry

    ETHOS, Issue 4 2001
    Assistant Professor Albert Schrauwers
    David Willson was the charismatic leader of a small Utopian Quaker sect, the Children of Peace (1812,89), who prophesied a millenarian transformation of the British empire. This article examines the confluence of social forces and historical conditions that made this charismatic ministry possible. Following Csordas, the emphasis is placed on the means by which followership is created, rather than on the personality of the leader. I argue that Willson's charismatic leadership was predicated upon inculcating a distinctive habitus, on shaping and molding cultural conceptions of self and of emotion, which create the distinctive disposition to obey infollowers. A "theology of mind" was critical to Willson's ministry, and the culturally and historically distinctive emotions and dispositions it described were inculcated in the communal ritual practice of "sitting in silence."

    Primary prevention of eating disorders: characteristics of effective programmes and how to bring them to broader dissemination

    EUROPEAN EATING DISORDERS REVIEW, Issue 3 2008

    Abstract Objective Based upon the observation of advances in the primary prevention of eating disorders (ED), it is summarized that school-based programmes, focusing on risk factors for females with interactive elements, dissonance induction and booster sessions yield significant effects even under strong methodological conditions. However, beyond the presented research findings it remains often unclear, if and how programmes can be brought to a broader dissemination within a community, region or country. Method Introducing the programme PriMa (German school-based programme for the primary prevention of anorexia nervosa (AN) for girls up to the age of 12), we describe the process of programme evaluation (including 1.006 girls from 42 schools in Thuringia, Germany, who participated in a controlled study using a pre-post-design and a 3 months follow-up), programme implementation and development of follow-up programmes, including an intervention for boys and flanking secondary preventive actions (such as a telephone hotline). Results Using standardized measures, the girls in the intervention group of PriMa reported significant improvements in body self esteem, figure dissatisfaction, knowledge and eating attitudes. The teachers, who conducted the programme, felt well qualified and were evaluated significantly positive by their students. Based upon the PriMa evaluation, we established a comprehensive health promotion programme at 60 Thuringian schools within the last 3 years, which could function as a model of a fruitful cooperation between a governmental institution (Thuringian Ministry of Culture) and a research institution (University Hospital Jena). Conclusions Existing programmes have the potential for effective prevention of ED. To confirm these effects under ,real world conditions' within a given community will still be a great challenge that often requires methodological and organizational concessions and compromises.
