    Full Text Available Globalization has led to an increase in commercial activities running on the illegal markets, its dynamics being largely determined by the balance between profitability and the major risks involved. Revenuesare significant, one example being those obtained from drug industry. In recent years, illicit drug trafficking has seen in Romania an unprecedented escalation, as a result of market liberalization and the movement of per sons and because of the extending the phenomenon both among producers and consumers. This article examines the size of the Romanian illegal drug markets, the countries of origin and drugtransit routes, as well as the profits made by the drug trafficking networks.

    2012-06-01

    Full Text Available Globalizing processes have profoundly shaped the European drugs situation. The illegal drug markets have reached to evolve and to transform all the advantages of this phenomenon, in their favor. Based on globalization aspects, the paper purpose is to present the main characteristics of illicit drugs market within European countries, from the last years. Furthermore the article is focused on the analysis of theoretical and empirical drugs literature, especially on the current reports and studies of EMCDDA and UNODC, which indicated certain drug sectors. Due to its richness, position and high demand of illegal drugs, Europe is viewed by criminal organizations as a transit area for heroin, cocaine, cannabis and synthetic drugs, and a big customer which continued to sustain this profitable enterprise, over the last decades. Regarding the drug problem, the governance needs to be reframed and to take account of economical, social and moral character. The simple connection of illegal drug markets with globalization, gives the originality note of the paper, which leads to some important new insights for future research and policy.

    Full Text Available The main characteristics of the Romanian illegal drug marketsAbstract: Narcotics trade has known a real transformation over time, which is also due to the great influence of globalization. Placed among the most profitable businesses in the world, the illegal drugs market has evolved very much on the Romanian territory in the last years. The purpose of this paper is to highlight the current situation of Romanian illicit drugs market, the symbiosis between supply and demand, the general prices of the main drugs, as well as the consumption problem and transit routes. Based on theoretical aspects, on recent surveys and investigation launched by UNODC, EMCDDA and ANA, the article provides some relevant answers regarding the Romanian illicit drugs market. Compared to the European countries, Romania remains a small costumer, cannabis and SNPP being the most consumed drugs among young people. Despite the political and economic situation, Romanian authorities are better prepared, a position that may help in dealing with further drug changes.

    Full Text Available The aim of this study was to test an explanatory model about illegal drug use among schooled adolescents. Different types of variables were used, including personal variables (academic self-esteem, social selfesteem and depressive symptoms, family variables (family functioning, father-mother communication, school variables (academic expectations, and social variables (community integration and participation. A sample of 1,285 adolescents, both males and females, aged between 12 and 20 years old, from four different schools in Monterrey, Mexico, was used. A structural equation model was used, explaining 20% of variance. The moderating effect of gender was explored. Results show a significant positive relationship betweencommunity context and illegal drugs use, mediated by social self-esteem only for boys. Likewise, a positive indirect relationship was found between the family context and drug use, mediated by social self-esteem, school self-esteem and academic expectations. Moreover, the family context showed a negative relationship with depressive symptoms, which in turn were related to drug use.

  11. Illegal drugs, anti-drug policy failure, and the need for institutional reforms in Colombia.

    Thoumi, Francisco E

    2012-01-01

    This paper is inspired by two anomalies encountered in the study of the illegal drugs industry. First, despite the very high profits of coca/cocaine and poppy/opium/heroin production, most countries that can produce do not. Why, for example, does Colombia face much greater competition in the international coffee, banana, and other legal product markets than in cocaine? And second, though illegal drugs are clearly associated with violence, why is it that illegal drug trafficking organizations have been so much more violent in Colombia and Mexico than in the rest of the world? The answers to these questions cannot be found in factors external to Colombia (and Mexico). They require identifying the societal weaknesses of each country. To do so, the history of the illegal drugs industry is surveyed, a simple model of human behavior that stresses the conflict between formal (legal) and informal (socially accepted) norms as a source of the weaknesses that make societies vulnerable is formulated. The reasons why there is a wide gap between formal and informal norms in Colombia are explored and the effectiveness of anti-drug policies is considered to explain why they fail to achieve their posited goals. The essay ends with reflections and conclusion on the need for institutional change.

    The aims of this study were to describe illegal drug abuse patterns in relation to the migration process and use of drug treatment centers among immigrant injected drug users (IDUs) involved in harm reduction programs, and to compare the characteristics of immigrant and native IDUs. Cross-sectional study of 748 IDUs aged ≥18 years attending harm reduction centers between 2008 and 2009. We explored differences in socio-economic status, illegal drug consumption, health status and use of treatment centers in native versus immigrant IDUs. We also described whether immigrant IDUs started using injected drugs before or after entering the host country. Immigrant IDUs tend to live alone more frequently, start injection at later ages, use heroin and inject it more frequently and use drug treatment centers less frequently than native IDUs. Seventy-six percent of immigrants began using illegal drugs before arriving at the host country. Those who started in other countries were residing in the host country for 5 years or less (63.9%). Overall, immigrant IDUs attended drug treatment centers (36.9%) less frequently than native IDUs (71.8%). In conclusion, migration could be a risk factor for illegal drug abuse initiation or increase in consumption, often with the adoption of local consumption patterns and aggravated due to a lower access to drug treatment centers.

    Legal and illegal drugs impose a considerable burden to the individual and to society. The misuse of addictive substances results in healthcare and law enforcement costs, loss of productivity and reduced quality of life. A social cost study was conducted to estimate the substance-attributable costs of alcohol, tobacco, illegal drugs and psychoactive medication to Belgian society in 2012. The cost-of-illness framework with prevalence-based and human capital approach was applied. Three cost components were considered: direct, indirect and intangible costs related to substance misuse. The direct and indirect cost of addictive substances was estimated at 4.6 billion euros in Belgium (419 euros per capita or 1.19% of the GDP) and more than 515,000 healthy years are lost due to substance misuse. The Belgian social cost study reaffirms that alcohol and tobacco impose the highest cost to society compared to illegal drugs. Health problems are the main driver of the social cost of legal drugs. Law enforcement expenditure exceed the healthcare costs but only in the case of illegal drugs. Estimating social costs of addictive substances is complex because it is difficult to determine to what extent the societal harm is caused by substances. It can be argued that social cost studies take only a 'snapshot' of the monetary consequences of substance misuse. Nevertheless, the current study offers the most comprehensive analysis thus far of the social costs of substance misuse in Belgium. Copyright © 2017 Elsevier B.V. All rights reserved.

    As several sedative-hypnotics are distributed illegally and are available domestically through media like the internet, their abuse is becoming a serious social problem. In the present study, four legal cases involving abuse of diazepam, midazolam, and/or zolpidem were proved by hair analysis using a simultaneous quantification method for the determination of diazepam (and its metabolites), lorazepam, midazolam, and zolpidem, which are often illegally abused in Korea, in hair that was developed and validated. Drugs and metabolites in hair were extracted using methanol followed by solid-phase extraction. The extracts were derivatized with N-methyl-N-(trimethylsilyl)trifluoroacetamide (MSTFA) and analyzed using gas chromatography-mass spectrometry in selected ion monitoring mode. The validation parameters of the method, including selectivity, linearity, limits of detection and quantification (LOQ), recovery, intra- and interassay precision and accuracy, and processed sample stability, were satisfactory. Moreover, the developed method was successfully applied to actual cases. In case 1, which involved a pop singer who was detained for suspected drug abuse, the concentrations of diazepam and nordiazepam were 5.7 and 2.0 ng/mg in nonpigmented hair and 6.6 and 1.8 ng/mg in pigmented hair, respectively. In case 2, 0.4 ng/mg zolpidem was detected in hair from a drug abuser who purchased illegally through the internet, and 0.2 ng/mg midazolam was detected in hair from an illegal drug seller in case 3. In case 4, diazepam (lower than the LOQ), nordiazepam (0.7 ng/mg), and zolpidem (0.7 ng/mg) were detected in hair from a medical doctor who abused drugs using forged prescriptions.

    Adolescence is the period of stress and strain. Researchers have shown that adolescents without strong social supports would have tendency towards smoking and drug abuse. This study aimed to evaluate the relationship between low self-esteem and illegal drug abuse. Participants were 943 grades nine to 12 high school students, from Sarakhs during 2010 - 2011. Adolescents participated in the study, completed two self-report questionnaires. The first questionnaire included questions about individual and family information, smoking and illegal drug abuse history, and the second was the Rosenberg's self-esteem scale. 53.8% of participants were male (507 individuals). The mean Rosenberg self-esteem score was 19.8 + 5.2, and the most frequent obtained scores were from 22 to 30. The difference of Rosenberg self-esteem score test between students who did not use any substance and those who had a history of smoking or drug abuse like heroin, pills, alcohols, betel nut (Nas) and other drugs (such as Pan and Hookah) was significant (P self-esteem scores between adolescents who lived with both or one of the parents, and those who did not live with any of parents, was significant (P = 0.04). There was also a significant association between the number of children in the family and self-esteem score. The current study showed significant association between the Rosenberg self-esteem test results and smoking, and illegal drug abuse like heroin, pills, alcohol, Nas, and other substances. Therefore, increasing self-esteem is essential for preventing the adolescents' emotional and behavioral disorders. This fact could guide us to the new approaches for smoking and drug-abuse prevention in adolescents.

  5. Risks, prices, and positions: A social network analysis of illegal drug trafficking in the world-economy.

    Science.gov (United States)

    Boivin, Rémi

    2014-03-01

    Illegal drug prices are extremely high, compared to similar goods. There is, however, considerable variation in value depending on place, market level and type of drugs. A prominent framework for the study of illegal drugs is the "risks and prices" model (Reuter & Kleiman, 1986). Enforcement is seen as a "tax" added to the regular price. In this paper, it is argued that such economic models are not sufficient to explain price variations at country-level. Drug markets are analysed as global trade networks in which a country's position has an impact on various features, including illegal drug prices. This paper uses social network analysis (SNA) to explain price markups between pairs of countries involved in the trafficking of illegal drugs between 1998 and 2007. It aims to explore a simple question: why do prices increase between two countries? Using relational data from various international organizations, separate trade networks were built for cocaine, heroin and cannabis. Wholesale price markups are predicted with measures of supply, demand, risks of seizures, geographic distance and global positioning within the networks. Reported prices (in $US) and purchasing power parity-adjusted values are analysed. Drug prices increase more sharply when drugs are headed to countries where law enforcement imposes higher costs on traffickers. The position and role of a country in global drug markets are also closely associated with the value of drugs. Price markups are lower if the destination country is a transit to large potential markets. Furthermore, price markups for cocaine and heroin are more pronounced when drugs are exported to countries that are better positioned in the legitimate world-economy, suggesting that relations in legal and illegal markets are directed in opposite directions. Consistent with the world-system perspective, evidence is found of coherent world drug markets driven by both local realities and international relations. Copyright © 2013 Elsevier B

  6. Can tobacco control endgame analysis learn anything from the US experience with illegal drugs?

    Science.gov (United States)

    Reuter, Peter

    2013-05-01

    The goals of tobacco control endgame strategies are specified in terms of the desired levels of tobacco use and/or tobacco related health consequences. Yet the strategies being considered may have other consequences beyond tobacco use prevalence, forms and related harms. Most of the proposed strategies threaten to create large black markets with potential attendant harms: corruption, high illegal earnings, violence and/or organised crime. Western societies of course have considerable experience with these problems in the context of prohibition of drugs such as cannabis, cocaine, heroin and methamphetamine. These experiences suggest that low prevalence has been achieved only by tough enforcement with damaging unintended consequences. Tobacco prohibition (total or partial) may not present the same trade-off but there is little basis for making a projection of the scale, form and harms of the attendant black markets. Nonetheless, these harms should not be ignored in analyses of the endgame proposals.

    2015-01-01

    Youth substance abuse is widely recognized as a major public health issue in Thailand. This study explores family and community risk and protective factors relevant to alcohol and illegal drug misuse in 1,778 Thai teenagers. Strong family attachment and a family history of antisocial behaviors were strongly associated with nearly all forms of substance abuse, with adjusted odds ratios ranging from 5.05 to 8.45. Community disorganization was strongly associated with self-reported substance use, although involvement in prosocial activities acted as a protective factor. The findings suggest that interventions that promote family cohesion and encourage community involvement may have considerable benefits in reducing substance abuse in Thai adolescents.

    In 2013, illegal drug use was responsible for 1.8% of years of life lost in the European Union, alcohol was responsible for 8.2% and tobacco for 18.2%, imposing economic burdens in excess of 2.5% of GDP. No single European country has optimal governance structures for reducing the harm done by nicotine, illegal drugs and alcohol, and existing ones are poorly designed, fragmented, and sometimes cause harm. Reporting the main science and policy conclusions of a transdisciplinary five-year analysis of the place of addictions in Europe, researchers from 67 scientific institutions addressed these problems by reframing an understanding of addictions.  A new paradigm needs to account for evolutionary evidence which suggests that humans are biologically predisposed to seek out drugs, and that, today, individuals face availability of high drug doses, consequently increasing the risk of harm.  New definitions need to acknowledge that the defining element of addictive drugs is ‘heavy use over time’, a concept that could replace the diagnostic artefact captured by the clinical term ‘substance use disorder’, thus opening the door for new substances to be considered such as sugar. Tools of quantitative risk assessment that recognize drugs as toxins could be further deployed to assess regulatory approaches to reducing harm. Re-designed governance of drugs requires embedding policy within a comprehensive societal well-being frame that encompasses a range of domains of well-being, including quality of life, material living conditions and sustainability over time; such a frame adds arguments to the inappropriateness of policies that criminalize individuals for using drugs and that continue to categorize certain drugs as illegal. A health footprint, modelled on the carbon footprint, and using quantitative measures such as years of life lost due to death or disability, could serve as the accountability tool that apportions responsibility for who and what causes drug

  10. Porous Borders : illegal Mining and Drug Trafficking as Latent Threats to Security

    Directory of Open Access Journals (Sweden)

    Diana Isabel Ocampo Rodríguez

    2015-10-01

    Full Text Available Transnational crime has become a latent threat to the security of the Colombian State and other countries of the region, calling for strategic actions by the security forces that go beyond the joint coordinated operations, requiring for its capacity and dynamism, the action within a framework of interoperability. In this sense, it provides a descriptive analysis of two major transnational threats affecting some Latin American countries and an approach given by the author on the strategy on how to deal with such challenges. This reflection paper is divided into three phases with a focus on qualitative research and documentary, descriptive and purposeful review. The first phase is an analysis of the evolution of the concept of security and transnational crime, the second, studies the specific case of drug trafficking and illegal mining, and the third one shows the recommendations made in order to demonstrate why should we deal with it in a coordinated manner and within a framework of cooperation and integration between states

  11. Antimicrobial drug use in Austrian pig farms: plausibility check of electronic on-farm records and estimation of consumption.

    2014-10-25

    Electronic drug application records from farmers from 75 conventional pig farms were revised and checked for their plausibility. The registered drug amounts were verified by comparing the farmers' records with veterinarians' dispensary records. The antimicrobial consumption was evaluated from 2008 to 2011 and expressed in weight of active substance(s), number of used daily doses (nUDD), number of animal daily doses (nADD) and number of product-related daily doses (nPrDD). All results were referred to one year and animal bodyweight (kg biomass). The data plausibility proof revealed about 14 per cent of unrealistic drug amount entries in the farmers' records. The annual antimicrobial consumption was 33.9 mg/kg/year, 4.9 UDDkg/kg/year, 1.9 ADDkg/kg/year and 2.5 PrDDkg/kg/year (average). Most of the antimicrobials were applied orally (86 per cent) and at group-level. Main therapy indications were metaphylactic/prophylactic measures (farrow-to-finish and fattening farms) or digestive tract diseases (breeding farms). The proportion of the 'highest priority critically important antimicrobials' was low (12 per cent). After determination of a threshold value, farms with a high antimicrobial use could be detected. Statistical tests showed that the veterinarian had an influence on the dosage, the therapy indication and the active substance. Orally administered antimicrobials were mostly underdosed, parenterally administered antimicrobials rather correctly or overdosed.

  12. New indicators of illegal drug use to compare drug user populations for policy evaluation

    Directory of Open Access Journals (Sweden)

    Francesco Fabi

    2013-11-01

    Full Text Available Background: New trends in drug consumption show a trend towards higher poly-use. Epidemiological indicators presently used are mostly based on the prevalence of users of the “main” substances and the ranking of harm caused by drug use is based on a single substance analysis.Methods: In this paper new indicators are proposed; the approach consider the segmentation of the population with respect to the frequency of use in the last 30 days and the harm score of the various substances used by a poly-user. Scoring is based on single substance score table reported in recent papers and principal component analysis is applied to reduce dimensionality. Any user ischaracterized by the two new scores: frequency of use score and poly-use score.Results: The method is applied to the drug user populations interviewed in Communities and Low Threshold Services within the Problem Drug Use 2012 survey in four different European countries. The comparison of the poly-use score cumulative distributions gives insight about behavioural trends of drug use and also evaluate the efficacy of the intervention services. Furthermore, the application of this method to School Population Survey 2011 data allows a definition of the expected behaviour of the poly-drug score for the General Population Survey to be representative.Conclusions: In general, the method is simply and intuitive, and could be applied to surveys containing questions about drug use. A possible limitations could be that the median is chosen for calculating the frequency of use score in questionnaires containing the frequency of drug use in classes.

    Full Text Available OBJECTIVE: Alcohol and other drug use appears to reduce decision-making ability and increase the risk of unsafe sex, leading to possible unplanned pregnancies, sexually transmitted diseases/human immunodeficiency virus/HIV transmission, and multiple sexual partners. This study aimed to test the hypothesis that risky sexual behaviors among adolescents are associated with legal and illegal drug use. METHODS: A national cross-sectional survey of 17,371 high-school students was conducted in 2010. Students were selected from 789 public and private schools in each of the 27 Brazilian state capitals by a multistage probabilistic sampling method and answered a self-report questionnaire. Weighted data were analyzed through basic contingency tables and logistic regressions testing for differences in condom use among adolescents who were sexually active during the past month. RESULTS: Approximately one third of the high school students had engaged in sexual intercourse in the month prior to the survey, and nearly half of these respondents had not used a condom. While overall sexual intercourse was more prevalent among boys, unsafe sexual intercourse was more prevalent among girls. Furthermore, a lower socioeconomic status was directly associated with non-condom use, while binge drinking and illegal drug use were independently associated with unsafe sexual intercourse. CONCLUSION: Adolescent alcohol and drug use were associated with unsafe sexual practices. School prevention programs must include drug use and sexuality topics simultaneously because both risk-taking behaviors occur simultaneously.

    Using magnetite/silica/poly(methacrylic acid-co-ethylene glycol dimethacrylate) (Fe(3)O(4)/SiO(2)/poly(MAA-co-EDMA)) magnetic microspheres, a rapid and high-throughput magnetic solid-phase extraction coupled with capillary zone electrophoresis (MSPE-CZE) method was developed for the determination of illegal drugs (ketamine, amphetamines, opiates, and metabolites). The MSPE of target analytes could be completed within 2 min, and the eight target analytes could be baseline separated within 15 min by CZE with 30 mM phosphate buffer solution (PBS, pH 2.0) containing 15% v/v ACN as background electrolyte. Furthermore, hydrodynamic injection with field-amplified sample stacking (FASS) was employed to enhance the sensitivity of this MSPE-CZE method. Under such optimal conditions, the limits of detection for the eight target analytes ranged from 0.015 to 0.105 μg/mL. The application feasibility of MSPE-CZE in illegal drugs monitoring was demonstrated by analyzing urine samples, and the recoveries of target drugs for the spiked sample ranging from 85.4 to 110.1%. The method reproducibility was tested by evaluating the intra- and interday precisions, and relative standard deviations of <10.3 and 12.4%, respectively, were obtained. To increase throughput of the analysis, a home-made MSPE array that has potential application to the treatment of 96 samples simultaneously was used.

    Streptococcus mutans, a Gram positive facultative anaerobe, is one among the approximately seven hundred bacterial species to exist in human buccal cavity and cause dental caries. Quorum sensing (QS) is a cell-density dependent communication process that respond to the inter/intra-species signals and elicit responses to show behavioral changes in the bacteria to an aggressive forms. In accordance to this phenomenon, the S. mutans also harbors a Competing Stimulating Peptide (CSP)-mediated quorum sensing, ComCDE (Two-component regulatory system) to regulate several virulence-associated traits that includes the formation of the oral biofilm (dental plaque), genetic competence and acidogenicity. The QS-mediated response of S. mutans adherence on tooth surface (dental plaque) imparts antibiotic resistance to the bacterium and further progresses to lead a chronic state, known as periodontitis. In recent years, the oral streptococci, S. mutans are not only recognized for its cariogenic potential but also well known to worsen the infective endocarditis due to its inherent ability to colonize and form biofilm on heart valves. The review significantly appreciate the increasing complexity of the CSP-mediated quorum-sensing pathway with a special emphasis to identify the plausible drug targets within the system for the development of anti-quorum drugs to control biofilm formation and associated risks.

    Full Text Available Background & Objective: Women’s role as a consumer or as a person who is facing with risks is so important in studies of substance abuse. However, major studies on this field aimed at studying on male population. Therefore, the aim of this study described the pattern of using illegal drugs among women belong to substance abuse control clinic of  Fasa city (south of Iran.Materials & Methods: This cross sectional study as a census was done on all authorized substance abuse treatment centers in Fasa in summer 2011. Information about demographic data, types of drugs, method of using, duration of addiction and onset age was extracted from the files of self-referred women. Results: There were 88 women in Fasa substance abuse treatment centers who were 2.8% of all registered patients. The Mean age of drug onset was 30.8±11.8 years. 62 persons (70.5% used opium and 55 persons (62.5% used Opium sap which were indicated thatthese two drugs were the two common ones among addicted women. With the average of 9.4±7.1 years, Opium had the longest duration of use. There is only one woman who had used injection during the last month. Two of the women had sexual relationship out of the family in the last month in which one of them had the unsafe contact as well.Conclusion: Presently, the pattern of drug abuse among women in Fasa is traditional and is based on the opium derivatives. However, according to the increasing rate and changes in drugs type, monitoring the behavior of drug abuser can have an effective role on the improvement of health in a community.

    The increasing illegal and on-line market of medicines and food supplements is helping the widespread diffusion of harmful counterfeit and forbidden products among consumers of developed countries. The objectives of this survey were the description of the main frauds recognized by public officers and the detection of illegal or counterfeit drugs and food supplements. Medicines and food supplements found by Police forces on the illegal market or resulting from seizures made by Italian Customs authorities were visually inspected and analysed to evaluate their quality and the presence of other undeclared substances. The visual inspection and the chemical analysis revealed unsuitable packaging (mostly lacking of adequate information for consumers), absence of the declared active substances and presence of undeclared active substances. Products containing doping agents, illegal substances and active ingredients requiring medical supervision were found. The present work confirmed the health risk associated with assumption of medicines purchased on the Internet and from the illegal supply chain and evidenced a new threat to consumer safety related to the presence of pharmaceutical active ingredients in food supplements claiming to contain only "natural ingredients".

    Full Text Available Background World health organization (WHO recommends the use of line probe assays (LiPAs for rapid drug susceptibility testing (DST. However, only a limited number of studies from Pakistan have documented the performance characteristics of line probe assays in testing multi-drug resistant (MDR strains of Mycobacterium tuberculosis (MTB. Objectives The objective of this work is to evaluate the diagnostic plausibility of the LiPA tests MTBDRplus and MTBDRsl on MDR MTB isolates from Pakistan. Patients and Methods This was a cross-sectional study conducted at the Indus hospital, Karachi. LiPA testing was performed on 196 smear-positive samples using BACTEC MGIT 960 as a gold standard. Results The sensitivity of MTBDRplus for isoniazid and rifampicin was found to be 88.8% and 90.2%, respectively, while sensitivity of MTBDRsl for fluoroquinolones, amikacin/capreomycin, and ethambutol was found to be 72.9%, 81.8%, and 56.6%, respectively. Conclusions The MTBDRplus and MTBDRsl genotypic testing can serve as useful additional tools for DST in a high-burden country like Pakistan provided it is used in combination with phenotypic testing.

  3. Illegal employment

    Full Text Available Since 2007 Labour Code contains the definition of dependent work, which can be carried out only in labour-law relations. The Amendment to Labour Code from 2012 makes the definition more precise, when it stipulates essential elements of dependent work and designates the others as conditions, under which dependent work should be carried out. The Amendment to Employment Act changes the definition of illegal work. Illegal work is a performance of dependent work by natural person except for labour-law relation, or if natural person – foreigner carries out work in conflict with issued permission to employment or without this permission. Since 2012 sanctions for illegal work were increased. Labour inspection is entitled to impose sanctions, in case of foreigners it is Customs Office. For control purposes employer is obliged to have copies of documents at the workplace proving the existence of labour-law relation. Goal of controls and high fines is to limit illegal employment of citizens of Czech Republic and foreigners as well. Illegal work has unfavourable economic impact on state budget. It comes to extensive tax evasions and also to evasions within health insurance and social security. If a concluded commercial-law relation meets the attributes of dependent work, then it stands for a concealed legal relationship. Tax Office can subsequently assess an income tax to businessman. Labour-law relationship enjoys a higher legal protection than commercial-law relationship; nonetheless it is not suitable to limit liberty of contract in cases when it is not unambiguously a dependent activity.

    Full Text Available BACKGROUND: The aim of the present study was to assess the risk of having a traffic accident after using alcohol, single drugs, or a combination, and to determine the concentrations at which this risk is significantly increased. METHODS: A population-based case-control study was carried out, collecting whole blood samples of both cases and controls, in which a number of drugs were detected. The risk of having an accident when under the influence of drugs was estimated using logistic regression adjusting for gender, age and time period of accident (cases/sampling (controls. The main outcome measures were odds ratio (OR for accident risk associated with single and multiple drug use. In total, 337 cases (negative: 176; positive: 161 and 2726 controls (negative: 2425; positive: 301 were included in the study. RESULTS: Main findings were that 1 alcohol in general (all the concentrations together caused an elevated crash risk; 2 cannabis in general also caused an increase in accident risk; at a cut-off of 2 ng/mL THC the risk of having an accident was four times the risk associated with the lowest THC concentrations; 3 when ranking the adjusted OR from lowest to highest risk, alcohol alone or in combination with other drugs was related to a very elevated crash risk, with the highest risk for stimulants combined with sedatives. CONCLUSION: The study demonstrated a concentration-dependent crash risk for THC positive drivers. Alcohol and alcohol-drug combinations are by far the most prevalent substances in drivers and subsequently pose the largest risk in traffic, both in terms of risk and scope.

    Full Text Available The United Nations drug control conventions of 1960 and 1971 and later additions have inadvertently resulted in perhaps the greatest restrictions of medical and life sciences research. These conventions now need to be revised to allow neuroscience to progress unimpeded and to assist in the innovation of treatments for brain disorders. In the meantime, local changes, such as the United Kingdom moving cannabis from Schedule 1 to Schedule 2, should be implemented to allow medical research to develop appropriately.

    Peter Anderson

    2017-03-01

    Full Text Available In 2013, illegal drug use was responsible for 1.8% of years of life lost in the European Union, alcohol was responsible for 8.2% and tobacco for 18.2%, imposing economic burdens in excess of 2.5% of GDP. No single European country has optimal governance structures for reducing the harm done by nicotine, illegal drugs and alcohol, and existing ones are poorly designed, fragmented, and sometimes cause harm. Reporting the main science and policy conclusions of a transdisciplinary five-year analysis of the place of addictions in Europe, researchers from 67 scientific institutions addressed these problems by reframing an understanding of addictions.  A new paradigm needs to account for evolutionary evidence which suggests that humans are biologically predisposed to seek out drugs, and that, today, individuals face availability of high drug doses, consequently increasing the risk of harm.  New definitions need to acknowledge that the defining element of addictive drugs is ‘heavy use over time’, a concept that could replace the diagnostic artefact captured by the clinical term ‘substance use disorder’, thus opening the door for new substances to be considered such as sugar. Tools of quantitative risk assessment that recognize drugs as toxins could be further deployed to assess regulatory approaches to reducing harm. Re-designed governance of drugs requires embedding policy within a comprehensive societal well-being frame that encompasses a range of domains of well-being, including quality of life, material living conditions and sustainability over time; such a frame adds arguments to the inappropriateness of policies that criminalize individuals for using drugs and that continue to categorize certain drugs as illegal. A health footprint, modelled on the carbon footprint, and using quantitative measures such as years of life lost due to death or disability, could serve as the accountability tool that apportions responsibility for who and what

    Full Text Available The study focuses on the assessment of the implications that criminal behavior has, not only at the start of treatment for drug taking but also during its development and results. With this aim in mind a sample of 209 patients who had applied for treatment were selected and assessed inthe principal object areas of analysis over a period of ayear anda half at six monthly intervals.The results indicate that time spent in a therapeutic centre significantly reduces criminal behaviour. However, those patients with a greater past history present more difficulties and give a poorer initial response, although during the period of follow-up these differences tend to disappear.

    In recent years, the repeated emergence of illegal drug ads driven by the temptation of huge economic benefits has been a seri- ous threat to the health and life safety of domestic citizens. The lack of supervision from relevant government departments and imperfect regulatory mechanism also provide the loop-hole for illegal drug ads. In addition, although medicine is a special commodity, consumers usually fall short of the essential knowledge and make blind decisions caused by urgent diseases, causing a large number of audiences be- ing deceived by illegal drug ads. To solve these problems, the authorities should enhance the supervision and punishment on illegal drug advertisers; further complete the drug ads censorship, implementing a prior control; improve drug ads release mechanism, strengthening the responsibility of the media; intensify rational drug use publicity and education for the consumers to resist the temptation of all kinds of false drug ads.%近年来,违法药品广告屡禁不止,已严重威胁了我国公民的身体健康和生命安全。巨大的经济利益诱惑是违法药品广告屡禁不止的重要原因。政府相关管理部门监管不力,监管机制尚不健全也为违法药品广告的刊播提供了可乘之机。同时,药品是一种特殊的商品,消费者药品知识普遍匮乏,加之病急乱投医的心理作用,使违法药品广告刊播之后总会有大批广告受众上当受骗。解决违法药品广告问题必须从多方面入手,加强对违法药品广告主体的监管与惩罚力度;进一步完善药品广告审查制度,实行事先控制;健全药品广告发布机制,强化媒体的责任;加强对广大消费者合理用药的宣传与教育,让消费者自觉抵制各类虚假药品广告的诱惑。

    2012-10-01

    This literature review outlines the current issues and debates relating to the dental health of adults with drug dependence. The dental health of adults with illegal drug dependence (IDD) continues to be under debate throughout dental practice, and the most appropriate model of care suitable to meet the high complex needs of this client group remains uncertain. The study aims to review and critically analyze available research relating to the oral health effects of illegal drug misuse and the dental health needs and status of adults with drug dependence. Second, it aims to identify and critically evaluate current models of dental service/care delivery, including relevant best practice guidance and potential barriers to dental access for adults with IDD. The available literature pertaining to dental health and adults with drug dependence are systematically reviewed and critically analyzed and evaluated in order to execute a rigorous investigation. The oral effects along with general medical complications associated with IDD are increasingly being recognized. There are substantive negative effects of IDD on oral health, particularly for those with opioid dependence; therefore, these clients have high complex dental needs and low use of dental services. Adults with drug dependence comprise a group with special dental needs and therefore need greater access to dental care than most people due to their high level of need. A high awareness of the implications for oral health care for adults with drug dependence is essential. Dental professionals have a key role in supporting the rehabilitation of these patients from potentially severe or fatal addictions. There is a distinct lack of national policy and guidance relating specifically to adults with drug dependence, and therefore, problems persist. Key findings and recommendations are presented to enhance the development of dental services for adults with IDD.

    Neither anti-illegal drug proponents nor their detractors have wholly plausible arguments for their positions, because neither takes responsibility for drug use sufficiently seriously. Instead, only a policy that places users' responsibility at the forefront of the problem is acceptable, one that is sufficiently respectful of actual or potential nonusers' rights not to be wrongfully harmed, directly or indirectly, by drug use, or coerced to support it in any way.

    Diniz, Debora; Castro, Rosana

    2011-01-01

    This article analyzes how the Brazilian news media covers the illegal market for misoprostol, the main drug used to induce abortion. A total of 1,429 news stories were retrieved from 220 print and electronic media channels from 2004 to 2009. The analysis included 524 stories from 62 regional and national newspapers. Misoprostol appeared repeatedly in the news, but was usually approached from a criminal perspective, unlike abortion as a whole, which the Brazilian media routinely covers as a religious, political, and public health issue. Misoprostol is part of the illegal gender-related drug market, along with drugs for weight loss and erectile dysfunction and anabolic steroids. Sixty-four (12%) of the news stories told life histories of women who had aborted with misoprostol. The women's ages ranged from 13 to 46 years, and socioeconomic status was associated with different experiences with abortion. Three characters appeared in the women's abortion itineraries: girlfriends (confidantes), go-betweens, and physicians. Stories of late-stage abortion are confused with the criminal characterization of infanticide and provide the extreme cases in the media's narrative on abortion.

  12. Looking for plausibility

    Abdullah, Wan Ahmad Tajuddin Wan

    2010-01-01

    In the interpretation of experimental data, one is actually looking for plausible explanations. We look for a measure of plausibility, with which we can compare different possible explanations, and which can be combined when there are different sets of data. This is contrasted to the conventional measure for probabilities as well as to the proposed measure of possibilities. We define what characteristics this measure of plausibility should have. In getting to the conception of this measure, we explore the relation of plausibility to abductive reasoning, and to Bayesian probabilities. We also compare with the Dempster-Schaefer theory of evidence, which also has its own definition for plausibility. Abduction can be associated with biconditionality in inference rules, and this provides a platform to relate to the Collins-Michalski theory of plausibility. Finally, using a formalism for wiring logic onto Hopfield neural networks, we ask if this is relevant in obtaining this measure.

    Full Text Available Para la década del noventa, la institucionalidad en Colombia se encontraba vulnerada frente a grandes carteles que traficaban y comercializaban con narcóticos. Fue en este contexto en el cual surgió el Plan Colombia, estrategia para recuperar la institucionalidad, reducir los cultivos ilícitos de coca y amapola, debilitar la economía de los grupos ilegales insurgentes, y finalmente recuperar la confianza inversionista. Hoy 13 años después de implementado el Plan, los cultivos ilícitos han tenido una disminución pero persisten, el tráfico y el comercio de psicoactivos han mutado y el consumo se ha incrementado, por lo tanto se cuenta con una necesidad social manifiesta por abordajes que realmente procuren un desarrollo sostenible y que den respuesta a una demanda comunitaria por acciones que procuren la prevención, la atención, el tratamiento y la rehabilitación de las personas, con servicios de salud adecuados. During the 1990's, institutionality in Colombia was negatively affected by large drug-dealing cartels. It was in this context where the Plan Colombia was born. This plan was a strategy to recover institutionality, reduce illegal coca and poppy plantations, weaken the economy of illegal insurgent groups, and restore investor confidence. Today, 13 years after the implementation of the Plan, the amount of illegal plantations has decreased. However they are still present, the traffic and trade of psychoactive substances have evolved, and consumption has increased. Therefore, there is now an evident societal need for strategies which address these issues that truly lead to sustainable development. Likewise, the community requires actions aimed at preventing this issue and promoting the care, treatment, and rehabilitation of those affected by this reality while providing adequate healthcare service

    The purpose of this study was to identify the major risk factors among adolescents who have either contemplated or attempted suicide. Along with successful suicides, suicide attempts and contemplation are coexisting factors that are prominent in the adolescent population and therefore warrant major concern. A secondary data analysis of the Youth Risk Behavior Survey (YRBS) was completed to explore the factors that may influence adolescents' thoughts or actions about suicidal behavior. The YRBS represents high-school students throughout 50 states. Nine questions from the YRBS were used to elicit information about the relationships among the risk factors: (1) Suicidal thoughts and attempts; (2) illegal drug use; (3) alcohol use; (4) tobacco use; and (5) depressive symptoms. Statistically significant relationships among the risk factors were found for adolescents. Adolescents considered suicide (15.8%); attempted suicide at least once (7.8%); were injured while attempting suicide (n = 2.7%). Our findings support the idea that illegal substance use can lead to suicidal thoughts and actions. Depression had a positive relationship with suicidal ideations, supporting similar studies suggesting that depression leads to suicidal action.

    The informal (and/or illegal) e-commerce of pharmaceutical formulations causes problems that governmental health agencies find hard to control, one of which concerns formulas sold as natural products. The purpose of this work was to explore the advantages and limitations of DOSY and HPLC-UV-SPE-NMR. These techniques were used to identify the components of a formula illegally marketed in Brazil as an herbal medicine possessing anti-inflammatory and analgesic properties. DOSY was able to detect the major components present at higher concentrations. Complete characterization was achieved using HPLC-UV-SPE-NMR, and 1D and 2D NMR analyses enabled the identification of known synthetic drugs. These were ranitidine and a mixture of orphenadrine citrate, piroxicam, and dexamethasone, which are co-formulated in a remedy called Rheumazim that is used to relieve severe pain, but it is prohibited in Brazil because of a lack of sufficient pharmacokinetic and pharmacodynamic information.

    Wheeler, David C.; Waller, Lance A.

    2009-03-01

    In this paper, we compare and contrast a Bayesian spatially varying coefficient process (SVCP) model with a geographically weighted regression (GWR) model for the estimation of the potentially spatially varying regression effects of alcohol outlets and illegal drug activity on violent crime in Houston, Texas. In addition, we focus on the inherent coefficient shrinkage properties of the Bayesian SVCP model as a way to address increased coefficient variance that follows from collinearity in GWR models. We outline the advantages of the Bayesian model in terms of reducing inflated coefficient variance, enhanced model flexibility, and more formal measuring of model uncertainty for prediction. We find spatially varying effects for alcohol outlets and drug violations, but the amount of variation depends on the type of model used. For the Bayesian model, this variation is controllable through the amount of prior influence placed on the variance of the coefficients. For example, the spatial pattern of coefficients is similar for the GWR and Bayesian models when a relatively large prior variance is used in the Bayesian model.

    Amphetamines, cannabinoids, cocaine, opiates, methadone, and benzodiazepines in authentic hair samples with drug concentrations around the medical and psychological assessment (MPA) guidelines cut-offs were screened by LUCIO-direct ELISA kits. Following confirmation of all positive and a significant number of negatively screened samples with gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods accredited for forensic purposes. Receiver operating characteristics (ROC) were plotted and the area under the curve (AUC) and overall misclassification rate (OMR) were calculated and compared to those obtained for the same drug classes in urine. While fulfilling the validation criteria of the German forensic guidelines, for almost all screening tests in hair and urine the AUC were greater than 0.8, indicating good to excellent performance. Moreover the AUC calculated for the detection of drugs in hair did not differ significantly to the AUC calculated for the detection of the same drug classes in urine, thus showing a comparable screening performance to the well accepted, previously published application of the same ELISAs for the detection of drugs at unconventionally low cut-offs in urine. For the first time, the validation of the immunoassay tests for the complete 6-drug panel MPA profile in hair and urine using a large population of authentic hair and urine samples with drug concentrations around MPA cut-offs, lower than conventional clinical or workplace drug testing guidelines cut-offs as well as those suggested by the Society of hair testing (SoHT) is presented.

    Full Text Available BACKGROUND: The aims of the study were to: a Examine the distribution of gender-stratified body mass index (BMI, eating attitudes and use of addictive substances, under the hypothesis of a confluent prevalence of weight abnormalities, eating disorders and substance abuse. b Demonstrate the extent to which family, peer-related and psychosocial factors are common elements in categories of compulsive behaviour. METHODOLOGY/PRINCIPAL FINDINGS: In the present cross-sectional study, data were collected through self reported questionnaires administered to a large sample of 33,185 15-19 years old adolescents (ESPAD®Italia, divided into weight categories based on the BMI percentile distribution. Multinomial analyses were adopted to address the influence of social, family, leisure time factors, Eating Attitude Test (EAT26 on the association between weight categories and drug use. Recent drugs use was more frequent in overweight and underweight adolescents (p<0.05, especially in females. An EAT26 score ≥20 was more common in overweight adolescents. Multinomial analysis abolished the relationship between overweight and the use of most drugs, implicating self-esteem, parents' educational level, and friendships as mediators of the association. Within the overweight category, adolescents reporting recent drug use, showed greater frequency of having drug-abusing friends (∼80%, and severe problems with parents and school (∼30% compared to overweight adolescents without recent drug use. CONCLUSION: The frequent association of overweight and substance use and the presence of common underlying social factors, highlights the need for an interdisciplinary approach involving individual-focused treatment models as well as public health, social and environmental changes to reduce food- and substances-related problems.

  1. Illegal performance enhancing drugs and doping in sport: a picture-based brief implicit association test for measuring athletes’ attitudes

    2014-01-01

    Background Doping attitude is a key variable in predicting athletes’ intention to use forbidden performance enhancing drugs. Indirect reaction-time based attitude tests, such as the implicit association test, conceal the ultimate goal of measurement from the participant better than questionnaires. Indirect tests are especially useful when socially sensitive constructs such as attitudes towards doping need to be described. The present study serves the development and validation of a novel picture-based brief implicit association test (BIAT) for testing athletes’ attitudes towards doping in sport. It shall provide the basis for a transnationally compatible research instrument able to harmonize anti-doping research efforts. Method Following a known-group differences validation strategy, the doping attitudes of 43 athletes from bodybuilding (representative for a highly doping prone sport) and handball (as a contrast group) were compared using the picture-based doping-BIAT. The Performance Enhancement Attitude Scale (PEAS) was employed as a corresponding direct measure in order to additionally validate the results. Results As expected, in the group of bodybuilders, indirectly measured doping attitudes as tested with the picture-based doping-BIAT were significantly less negative (η2 = .11). The doping-BIAT and PEAS scores correlated significantly at r = .50 for bodybuilders, and not significantly at r = .36 for handball players. There was a low error rate (7%) and a satisfactory internal consistency (r tt  = .66) for the picture-based doping-BIAT. Conclusions The picture-based doping-BIAT constitutes a psychometrically tested method, ready to be adopted by the international research community. The test can be administered via the internet. All test material is available “open source”. The test might be implemented, for example, as a new effect-measure in the evaluation of prevention programs. PMID:24479865

    This study was designed to reveal the current status of the rehabilitation support system for patients with Illegal Substance Use Disorder (ISUD). From among 465 patients who had been admitted to a psychiatric hospital in Tokyo within the past 10 years by order of the prefectural governor, 65 patients with ISUD were selected for inclusion in this study. Based on whether or not the person was arrested at the time of discharge, whether or not urine drug monitoring was ordered, and the results of the monitoring, each subject was classified into one of the following four types: 1) Arrested; 2) Not arrested and no urine drug monitoring; 3) Not arrested and positive urine drug monitoring results; and 4) Not arrested and negative urine drug monitoring results. In Group 1, every subject underwent urine drug monitoring prior to an involuntary examination; however, even though 10 percent of the subjects in this study were found to have positive results on urine drug monitoring, none of them were arrested. Moreover, 40 percent of the study subjects were not subjected to urine drug monitoring, and about 30 percent of non-arrested subjects were shown not to have used any illegal substances. Based on these results, it appears to be ideal for patients in Group 1 to apply to a diversion program, followed by medical treatment for addiction. To avoid the elimination of patients from medical services due to the vagueness of the classifications, whether or not judicial administration is required at the time of police intervention should be clearly and appropriately clarified for patients in Groups 2 and 3. Patients in Group 4 may experience a relapse of psychiatric symptoms, even if they do not use illegal substances; therefore, it is necessary for designated hospitals to perform medical treatment interventions responsibly for both endogenous psychosis and substance abuse, and to collaborate with appropriate social support facilities within the community regarding the medical

    2012-01-01

    Faced with the rapidly growing increase of designer drug abuse, particularly amongst the younger generation, various legislative strategies are currently employed world-wide for tackling this problem - however with mixed results. The key issue is that the producers of DDs are able to either exploit existing legal substances intended for other uses, but which have been found to possess psychoactive properties, or to synthesise new psychoactive substances by introducing chemical modifications, often very minor ones, thereby avoiding the prohibited use of chemicals included on any banned lists. Some countries opt to ban new drugs as and when shown or considered to be harmful, while others introduce sweeping bans based on chemical structure. Nevertheless, an ever increasing diversity of new DDs are constantly appearing on domestic and Internet markets. Poland, together with the UK and Eire, has placed temporary bans on all DDs whenever they have been identified, thus enabling sufficient time for assessing their potential hazards to health. Part of this 'holding' strategy entails a thorough review of the scientific literature, including expert opinion when direct evidence is lacking, as well as information received from EU support organisations Europol and the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA). This paper, in two parts, therefore aims to provide an up-to-date summary review of available scientific evidence on the harm caused by the six main chemical groupings of DDs found in drug seizures of illegal products recently made in Poland. The first part is devoted to Cannabinoids and Cathinones derivatives. Ensuing legislation can therefore be rapidly formulated to make the bans permanent as appropriate.

    2007-05-01

    The purpose of this monograph is to provide information on drug retention times in the human body. The information provided is based on plausible illegal drug use activities that might be engaged in by a recreational drug user. Based on anecdotal evidence, most people “party” during extended time away from the work environment. Therefore, the following scenarios were envisioned: (1) a person uses an illicit drug at a party on Saturday night (infrequent user); (2) a person uses a drug one time on Friday night and once again on Saturday night (infrequent user); and (3) a person uses a drug on Friday night, uses a drug twice on Saturday night, and once again on Sunday (frequent user).

    familiares, amigos y los medios de comunicación aproximan a las drogas o no, reforzando la pertinencia de la promoción de la salud y prevención entre los ciegos.OBJECTIVES: To explore and describe similarities and differences between blind men and women's perceptions of the use of illegal drugs. METHODS: A qualitative descriptive study was conducted from october 2006 to march 2007 with blind men and women from an association of blind in fortaleza, ce, brazil. data were collected through interviews. the sample consisted of 7 men and 5 women. the sample size was determined through theme saturation. RESULTS: Content analysis suggested three themes: (1 what i know - participants define what illegal drug is and the scope of the problem; (2 what i experienced - they report on their personal and family experiences with the use of illegal drugs; and (3 what i think about prevention - they describe their opinions about strategies that can be used for the prevention of the use of illegal drugs. CONCLUSIONS: Illegal drugs were understood as a public health problem, affecting the user's lives and the society as a whole. relatives, friends, and the media may or may not influence the use of illegal drugs, which strengthen the relevance to address illegal drug prevention among the blind as well as health promotion activities.

    Epstein, G S; Hillman, A L; Weiss, A

    1999-01-01

    This paper studies the prospects of implementation of guest-worker programs by governments that are based on an intended temporary presence of foreign workers. The purpose of guest- worker programs is to alleviate sector-specified labor shortages. The intention of a temporary stay is reflected in families left behind, and in the employers that often take responsibility for their workers' housing, health care, and other services during the temporary stay. Yet, some foreign workers prefer not to return home. In this case, the government and the employer ensure that the worker returns home after his legal employment. The government's intention is revealed through a policy granting the worker a temporary admission to the country. The legal employer pays a bond to bring in the foreign worker, and should the worker switch to illegal employment, the employer loses the value of the bond. Despite the intentions of the government, the legal employer can find his position to be quite precarious. If his legal workers are still with him at the end of the legal period of employment, it is only because they have rejected an illegal offer or they have never received an offer; and, if the worker leaves the legal employer just before he is to be deported, the employer has paid twice, once through the higher second-period wage and the second time by way of the forfeited bond. The anticipations for success of the intentions of temporary guest-worker programs can only be overly optimistic if the instruments used to enforce the policy are a bond and duration of permissible stay. The accumulation of an illegal population appears to be an inevitable consequence of a guest-worker program.

    Full Text Available Illegal, unreported and unregulated (IUU fishing is a worldwide phenomenon. Its extent and its environmental,economic and social consequences are such that it has become a priority issue at international level. IUU fishingcontributes to the depletion of fish stocks and jeopardises protection and recovery measures put in place to ensure theviability of resources. It represents unfair competition for those who exploit fish resources legally. The Commissionhave been involved in the fight against IUU fishing for over a decade and in 2002 the Commission adopted an ActionPlan against IUU fishing inspired by the FAOs International Plan of Action to prevent, deter and eliminate IUUfishing of 2001. However, despite regional and international efforts to stop IUU fishing the phenomenon is still agrowing problem and as a result, the European Community intensified its action towards IUU fishing by launching aconsultation process in 2007. A Proposal to prevent, deter and eliminate IUU fishing was adopted in October 2007and a Regulation to prevent, deter and eliminate illegal, unreported and unregulated (IUU fishing was adopted on 29September 2008, after a unanimous political agreement.

    Thirty-three shopping bags, commonly encountered in the packaging of drug doses, were characterized by wide angle X-ray diffraction (WAXD). Using this single technique, without sample preparation, nearly all the considered samples could be differentiated, achieving a discriminating power of 0.992. The rather large degree of variability existing in grocery bags, even though they are mass produced, was shown, confirming that these items can be useful in tracing the source of illicit drug doses.

    The authors examined benzodiazepine and sedative-hypnotic positive cases of drivers under the influence (DUI) in Finland from 1997 to 2008. Factors studied were the number of cases positive for the most commonly encountered of these pharmaceuticals, simultaneous use of amphetamine and/or cannabis, and the relationship between the number of DUI cases and overall sales in Finland for the individual pharmaceuticals. Data for 20037 cases positive for the relevant drugs were retrieved from the laboratory database of the Alcohol and Drug Analytics Unit, National Institute for Health and Welfare. Toxicological results were from blood analysis. Drug sales figures for each pharmaceutical were obtained from the Finnish Medicines Agency. An increase in DUI cases that were positive for the drugs studied was evident, which reflected the overall increase in positive DUI cases detected annually. The proportion of relevant cases was typically 75% or higher of all positive DUI cases up to 2003, the year that the Finnish zero tolerance law was introduced, and then decreased to 66.2% in 2008. Diazepam was consistently the most commonly detected nonmetabolite drug. The prevalence of clonazepam and alprazolam increased sharply from 2004 onward. Metabolites of diazepam, nordiazepam, temazepam, and oxazepam, were other common findings. Associated use of amphetamine and/or cannabis was also common in these DUI cases, typically between 56% and 66% of cases. An increase in the number of DUI cases showing combined use of benzodiazepines and sedative-hypnotics with amphetamines in particular was apparent after zero tolerance legislation and the introduction in 2005 of an effective on-site screening device for the stimulant. Ratios of DUI cases to sales figures showed an increase in detection of clonazepam-positive DUI cases from 2003. Diazepam, midazolam, and alprazolam also exhibited relatively high ratios, which increased from 1997 to 2008.

    The abuse and misuse of benzodiazepines and zolpidem are widespread internationally. Their illegal distribution has raised their abuse to a serious level, and they are often misused in crimes. In the present study, 18 cases involving the illegal use of benzodiazepines and/or zolpidem were proved by hair analysis. The drugs were extracted from the hair samples using methanol and analyzed using LC-MS/MS. The cases were classified according to case history: five of illegal use in medical staff, eight through inappropriate or illegal distribution, and five related to drug-facilitated crimes. Among the 18 cases, zolpidem was identified in eight, alprazolam in seven, diazepam in six, and clonazepam in four. The drug concentrations ranged from drugs, programs for prescription drug monitoring and supervision of those handling these drugs are both recommended.

    Three data sets were used to estimate joint and conditional probability distributions between various variables of interest in bank fraud and embezzlement (BF and E) cases of $10,000 dollars or more, computer-related crime cases of various types, and cases of insider theft from drug manufacturers and distributors. This report describes in tabular form the information contained in the three rather extensive data sets from industries facing insider threats which, in one or more dimensions, are analogous to insider threats potentially confronting managers in the nuclear industry. The data in Tables 1 through 29 were computed from the 313 cases of bank fraud and embezzlement (BF and E) representing losses of $10,000 or more reported to the Federal Deposit Insurance Corporation (FDIC) for the period 1977 to 1978. The data in Tables 30 through 64 were computed from the 461 cases of computer-related crime obtained from SRI International for the period 1958 to 1978. These incidents include inventory manipulations designed to hide errors, phony entries used to cover embezzlements, schemes used to penetrate a system and surreptitiously bring about a system crash, and sabotage. The data in Tables 65 through 67 were computed from data reported by the Drug Enforcement Agency (DEA) for the period 1973 to 1978. These data, though limited, provided several interesting insights into the insider-threat problem.

    In this study, we sought to determine what impact the banning of 3, 4- methylenedioxypyrovalerone (MDPV) had on the incidence of MDPV-positive findings and on user profiles in driving under the influence of drugs (DUID) and postmortem (PM) investigations in Finland. All MDPV-positive cases and a selection of corresponding court cases between 2009 and 2012 were examined. The median serum concentration of MDPV in DUID cases was 0.030 mg/L and in PM blood 0.12 mg/L. The number of MDPV-positive cases decreased both in DUID and PM investigations after the drug was banned. The decrease in the mean monthly numbers of MDPV-positive DUID cases was 51.1%. In court cases, MDPV was rarely mentioned until banned and frequently mentioned thereafter. Of the convicted, 37% were without a fixed abode, 98% had other charges besides that of DUID, and 13% appeared in the study material more than once. In MDPV-positive PM cases, the proportion of suicides was very high (24%). Research on new psychoactive substances is required not only to support banning decisions but more importantly to be able to provide a scientific assessment of the risks of these new substances to the public and potential users.

Although strictly speaking no analogy can be drawn between the charging provisions for income tax and VAT, it is clear that in the determination of the taxability of illegal income, the courts applied the principle of tax neutrality. In terms of the principle of tax neutrality, taxes are not concerned with the legality or illegality of a transaction, but rather with whether the transaction complies with the requirements for it to be taxed or not. That said, the European Court of Justice has a different approach in applying this principle. According to the European Court of Justice where the intrinsic nature of the goods excludes it from the commercial arena (like narcotic drugs it should not be subject to VAT, but where the goods compete with a legal market it must be subject to VAT. Charging VAT on illegal transactions might give the impression that government benefits from criminal activities. However, if illegal transactions are not subject to VAT the trader in illegal goods will benefit as his products will be 14% cheaper than his rival’s. Is this necessarily a moral dilemma? In conclusion three arguments can be deduced on the question if illegal transactions should be subject to VAT:1. Illegal transactions should not be taxed at all. Illegal goods or services fall outside the sphere of the application of the charging provision in section 7(1 of the VAT Act. Moreover, taxing illegal transactions lends a quasi-validity to the contract and gives the impression that

    A simple and inexpensive method for the identification of four substituted amphetamines, namely, 3,4-methylenedioxy methamphetamine (MDMA), methamphetamine (MA), 3,4-methylenedioxy amphetamine (MDA) and 3,4-methylenedioxy-N-ethylamphetamine (MDEA) was developed using an in-house constructed semi-automated portable capillary electrophoresis instrument (CE) with capacitively coupled contactless conductivity detection (C(4)D). Arginine 10mM adjusted to pH4.5 with acetic acid was found to be the optimal background electrolyte for the CE-C(4)D determination of these compounds. The best detection limits achieved with and without a sample preconcentration process were 10ppb and 500ppb, respectively. Substituted amphetamines were found in different seized illicit club drug tablets and urine samples collected from different suspected users. Good agreement between results from CE-C(4)D and those with the confirmation method (GC-MS) was achieved, with correlation coefficients for the two pairs of data of more than 0.99.

    "This paper analyzes the supply-side determinants of illegal immigration using a three-sector general equilibrium model of the source country. Agricultural liberalization raises illegal immigration while liberalization of the high tech sector reduces it. In contrast, capital mobility in the source country renders trade policy ineffective for controlling illegal immigration. Paradoxically, increased enforcement (by the host country) may raise source country unskilled wages, although illegal immigration falls. Finally, under capital mobility, a rise in the source country restrictions on capital inflow raises the level of illegal immigration and reduces the effectiveness of border enforcement efforts by the host country."

    Full Text Available Illegal migration is a mobile phenomenon, which ignores national borders, a threat that originates outside the community and extends to Western societies. This phenomenon is becoming larger and irregular migrants are often in a precarious situation and exposed to the criminals involved in various manifestations of organized crime. The future risk factors of the illegal migration are the demographic bomb, because the population is decreasing in European countries and increasing rapidly in poorer countries, droughts, floods, deforestation, that cause conflicts between climate refugees , extreme poverty, totalitarian regimes, epidemics, can trigger millions of people, the elderly and the working population imbalance which leads to the permanent import of immigrants To combat this phenomenon, states must engage and cooperate with each other. Measures taken by states must balance their integration policy for immigrants, legally residents and asylum policy to comply with international conventions. Also, states must adopt anti-immigrant policies, consisting of subordination visa policy to the interests of international security and exchange of information and, not least, to continue the Schengen process, as a value of humanitarian law applied in the field. The aim of the research is to characterize this dangerous phenomenon for the society and the goal is to identify strategies to combat illegal migration.

    In this paper, we show that the marginal distribution of plausible values is a consistent estimator of the true latent variable distribution, and, furthermore, that convergence is monotone in an embedding in which the number of items tends to infinity. We use this result to clarify some of the misconceptions that exist about plausible values, and also show how they can be used in the analyses of educational surveys.

    "Economic theory suggests that transnational migration results from the push-pull effect of wage differentials between host and source countries. In this paper, we argue that political instability exacerbates the migration flow, with greater instability leading to relatively larger flows. We conclude then that an optimal solution to the illegal immigration problem requires proper coordination of immigration and foreign policies by the host country. A narrow preoccupation with tougher immigration laws is wasteful and may be marginally effective." Emphasis is on the United States as a host country.

For this reason, a theoretical model is developed based on the interconnection between the illegal and legal labour market. The big landowner analysed exercises a monopolistic power in the contracting of illegal manual labour. The application of a tariff in two parts permits this big landowner to obtain a greater surplus from the worker.

    Full Text Available Tropical deforestation such as in the Amazon can be studied well from a green criminological perspective. Ethnographic research methods form a useful way to get insight into the dynamics and complexity of tropical deforestation, which often is illegal. This article gives an account of various ethnographic visits to the rainforests of the Amazon in the period 2003-2014. Ethnographic methods provide insight into the overlap between the legal and illegal, the functioning (or not of state institutions, the power of (corporate lobbies, and why tropical deforestation correlates with crimes such as corruption and violence. The use of ethnographic methods in forest areas where trustworthy state actors and institutions are not very present can also present danger and raise ethical issues (such as when the researcher, for reasons of safety, does not present as a criminological researcher. However, a large advantage of ethnographic visits to tropical rainforests is that they allow the gathering of local views and voices, which rarely reach the international level. These local views lead to interesting contradictions at the international level where corporate views and lobbies dominate.

    Results. Ninety-five percent of a total group of 172 OP of Champagne county filled the postal questionnaire. More than 80% of OP's replies identified illegal PSW. The average prevalence of PSW exposure was 0.7% of the total working population. Environmental tobacco smoke (ETS levels were considered between low and medium for most passive smokers (71%. Main features exposure to ETS at work for non-smokers was associated with female gender (69.5%, age between 40 and 49 years (41.2% and belonging to tertiary sector (75.6%. Environmental tobacco smoke exposures at work was firstly in the office for 49.7% of the subjects and secondly in the restroom for 18% of them. Main medical symptoms encountered by non-smokers were respiratory tractus irritation (81.7%. Eighty-three percent of OPs indicated solution to eradicate PSW. Illegal PSW is really weaker than fifteen years ago. However, the findings support a real ban on smoking in the workplace in order to protect all workers.

    CERN Document Server

    Martin, Ryan

    2012-01-01

    In the frequentist program, inferential methods with exact control on error rates are a primary focus. Methods based on asymptotic distribution theory may not be suitable in a particular problem, in which case, a numerical method is needed. This paper presents a general, Monte Carlo-driven framework for the construction of frequentist procedures based on plausibility functions. It is proved that the suitably defined plausibility function-based tests and confidence regions have desired frequentist properties. Moreover, in an important special case involving likelihood ratios, conditions are given such that the plausibility function behaves asymptotically like a consistent Bayesian posterior distribution. An extension of the proposed method is also given for the case where nuisance parameters are present. A number of examples are given which illustrate the method and demonstrate its strong performance compared to other popular existing methods.

Restricting ourselves to the single-agent case, we determine when such models are indistinguishable in the logical language containing conditional belief, i.e., we...... define a proper notion of bisimulation, and prove that bisimulation corresponds to logical equivalence on image-finite models. We relate our results to other epistemic notions, such as safe belief and degrees of belief.

    Full Text Available Illegal and unreported fishing contributes to overexploitation of fish stocks and is a hindrance to the recovery of fish populations and ecosystems. This study is the first to undertake a world-wide analysis of illegal and unreported fishing. Reviewing the situation in 54 countries and on the high seas, we estimate that lower and upper estimates of the total value of current illegal and unreported fishing losses worldwide are between $10 bn and $23.5 bn annually, representing between 11 and 26 million tonnes. Our data are of sufficient resolution to detect regional differences in the level and trend of illegal fishing over the last 20 years, and we can report a significant correlation between governance and the level of illegal fishing. Developing countries are most at risk from illegal fishing, with total estimated catches in West Africa being 40% higher than reported catches. Such levels of exploitation severely hamper the sustainable management of marine ecosystems. Although there have been some successes in reducing the level of illegal fishing in some areas, these developments are relatively recent and follow growing international focus on the problem. This paper provides the baseline against which successful action to curb illegal fishing can be judged.

  1. Illegal markets: Estimates of global proceeds

    2015-01-01

    Full Text Available Illegal markets represent a phenomenon of considerable economic, political and social significance whose annual income exceeds the value of a thousand billion USD. Illegal market participants are beyond the reach of government institutions and rule of law while social connections and personal acquaintances play an important role of functional substitute. In the last decade there was a significant increase of illegal trafficking of narcotics, people, fire arms, counterfeit products and natural resources. Both selling and purchase of these as well as other kinds of products and services at illegal markets are generally characterized by high level of organization and presence of strong criminal groups and networks. Although these activities existed in the past their present scope and geographic distribution are without precedent. Measuring unlawful financial flows at illegal markets represents quite a complex task. Various estimates are the result of inexistence of uniform and generally accepted methodology. In addition to this, the special problem is also the consensus of market actors, because of which the phenomenon of illegal markets and distribution of products and services at these markets is rather hidden. The paper defines and analyzes the key features of illegal markets, the role of organized crime at illegal markets, as well as the estimates of the values of financial flows at the markets of counterfeit products, narcotics, and people as goods, or human organs and sexual services, weapons, tobacco products and dirty money.

    Full Text Available Emerging adulthood marks a critical developmental juncture during which some individuals disengage from the illegal behavior of their adolescence while others continue to use substances and commit crimes. While risk factors for delinquency during adolescence are well studied, factors that influence persisting or desisting from illegal activities during emerging adulthood have not been fully explored. This mixed methods study utilizes a sample of college students aged 18-25 (N=74 and examines factors differentiating those who abstained from illegal behaviors, desisted from illegal behaviors, and persisted in illegal behaviors. Multinomial logistic regression models indicated peers offending and hours spent studying predicted desisting and peers offending predicted persisting (compared to the abstaining group. Three qualitative themes: family and peer bonds, morals and values, and fear of consequences further explained factors influencing emerging adults’ persisting and desisting choices. Implications for social work practice are explored.

    Full Text Available In the economic and social plan, tax evasion is a reality seen in various forms, such as the keeping of not realistic accounting books; willful destruction of documents that might lead to the discovery of real product deliveries, adopted prices, fees received or paid, establishing false customs declarations for the goods import or export, preparing false tax declarations, while knowingly not mentioning but a portion of the incomes. The largest tax evasion - 60% - is generated from VAT, while social contributions generate approximately 24% of the total fiscal evasion, mainly through the phenomenon of “illegal work” (employees in the underground economy. For this purpose it is necessary a deep reform of the taxes administration, mainly in the direction of increasing the degree of tax collection. The phenomenon as a whole is very difficult to control and to quantify and to this contribute also the tax laws’ peculiarities, tax policies, corruption and the standard of living

  5. Eliminating Illegal Timber Consumption or Production: Which Is the More Economical Means to Reduce Illegal Logging?

    2016-08-01

    Full Text Available Illegal logging, with its related trade of illegally harvested timber, is one of the main environmental and economic problems worldwide. Eliminating illegal timber consumption and production are two practical means to reduce illegal logging. However, the problem of determining which of the two means is more economical remains to be analyzed. In this study, an input–output analysis was conducted to evaluate the consumption and production of illegal timber in different countries. The Global Forest Products Model (GFPM was employed to analyze the effects of eliminating illegal timber consumption and production on the added value of the forest sector at global and national levels. Results indicated that eliminating illegal timber production is more economical than eliminating consumption at the global level. The former is estimated to decrease the added value of the global forest sector only by 3.37% compared to 7.31% by the latter in 2030. Eliminating the production of illegal timber will result in uneven distribution of social wealth in the forest sector, and will pass the cost of reducing illegal logging onto developing countries. Developed countries would gain more added value and market scale than the global average, whereas developing countries would suffer a loss if illegal timber production is eliminated. Hence, developed countries are encouraged to provide financial support to help developing countries reduce illegal logging.

    The aim of this study was to describe the typical profile, and to assess the motivations of women who underwent illegal abortion with misoprostol in Guadeloupe (French West Indies). We conducted a 1-year prospective study on women who consulted after failure or complication of an illegal abortion with misoprostol. Fifty-two cases of illegal abortion with misoprostol were recorded. The most common profile was an unemployed woman, who was unmarried, foreign-born, had no medical insurance, and a low level of education; the median age was 28 (range 17 to 40). The justifications given were that the legal procedure was considered to be too slow, the young age of the woman, the ease of the self-medication procedure, a history of illegal abortion by misoprostol in the woman's country of origin, ignorance of the legal process, and financial and/or administrative problems. The problem of illegal abortion is probably underestimated in Guadeloupe and possibly France. This description of the profile of the population concerned and the justifications for choosing illegal abortion by misoprostol provides elements allowing better focus of education concerning abortion, contraception and family planning. Access to legal abortion centers should also be improved. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

    Recent advances in genomics, recombinant expression technologies and peptide synthesis have led to an increased development of protein and peptide therapeutics. Unfortunately this goes hand in hand with a growing market of counterfeit and illegal biopharmaceuticals, including substances that are still under pre-clinical and clinical development. These counterfeit and illegal protein and peptide substances could imply severe health threats as has been demonstrated by numerous case reports. The Belgian Federal Agency for Medicines and Health Products (FAMHP) and customs are striving, together with their global counterparts, to curtail the trafficking and distributions of these substances. At their request, suspected protein and peptide preparations are analysed in our Official Medicines Control Laboratory (OMCL). It stands to reason that a general screening method would be beneficiary in the battle against counterfeit and illegal peptide drugs. In this paper we present such general screening method employing liquid chromatography-tandem mass spectrometry (LC-MS/MS) for the identification of counterfeit and illegal injectable peptide preparations, extended with a subsequent quantification method using ultra-high performance liquid chromatography with diode array detection (UHPLC-DAD). The screening method, taking only 30 min, is able to selectively detect 25 different peptides and incorporates the proposed minimum of five identification points (IP) as has been recommended for sports drug testing applications. The group of peptides represent substances which have already been detected in illegal and counterfeit products seized by different European countries as well as some biopharmaceutical peptides which have not been confiscated yet by the controlling agencies, but are already being used according to the many internet users forums. Additionally, we also show that when applying the same LC gradient, it is also possible to quantify these peptides without the need for

    Self-medication is well known risk in Latin America. This situation can partly be explain by the difficult access to doctors and poorly regulated drug sales. Illegal Latino-American immigrants import their practice of self-medication and their drugs with them. The economic advantage of this practice makes it popular and confronts medical practitioners to question the benefice/risk of such behavior. Taking the particular situation of illegal Latino-American immigrants, this review discusses the necessity of abording systematically the question of self-medication during a medical consultation.

    Full Text Available Aim. The article considers a notion of subject of such crime as illegal hunting. Only a man can be a subject of this crime. The content of such crime is revealed with the help of such properties as guilt, motive and aim. The article considers different properties of a subject of crime: 1 Physical nature Illegal actions can be committed by a man directly or indirectly. If during hunting a dog without its master’s command got a wild animal, the hunter is not liable as here intentional crime is absent. Juridical entities also are not admitted a subject of crime, only their representative if he committed this crime. 2 Criminal capacity. A person is not liable for this crime if he committed it in the state of criminal incapacity (CC Art.21. If illegal hunting is committed by a person in the state of drunkenness he is admitted capable and is liable for the crime(Criminal Code art.23. 3 A definite age. According to Art.23 of RF CC criminal responsibility for illegal hunting comes from the age of 16 . Performance of art.11, 12, 13 of CC concerns citizens of Russia, foreign citizens and persons without citizenship who committed poaching on the territory of Russia. Thus, the subject of poaching is a capable physical person reached the age of 16 by the moment of committing the crime.

    Sundström, Aksel

    2016-10-01

    This review synthesizes the literature studying illegality and government corruption in forest management. After discussing the theoretical connections between different types of corruption and illegal forest-related activities it describes the major trends in previous studies, examining cross-national patterns as well as local in-depth studies. Both theory and available empirical findings provide a straightforward suggestion: Bribery is indeed a "door opener" for illegal activities to take place in forest management. It then discusses the implications for conservation, focusing first on international protection schemes such as the REDD+ and second on efforts to reduce illegality and bribery in forest management. Key aspects to consider in the discussion on how to design monitoring institutions of forest regulations is how to involve actors without the incentive to engage in bribery and how to make use of new technologies that may publicize illegal behavior in distant localities. The review concludes by discussing avenues for future research. Copyright © 2016 Elsevier Ltd. All rights reserved.

    An important group of suspected illegal cosmetics consists of skin bleaching products, which are usually applied to the skin of the face, hands and décolleté for local depigmentation of hyper pigmented regions or more importantly, for a generalized reduction of the skin tone. These cosmetic products are suspected to contain illegal active substances that may provoke as well local as systemic toxic effects, being the reason for their banning from the EU market. In that respect, illegal and restricted substances in cosmetics, known to have bleaching properties, are in particular hydroquinone, tretinoin and corticosteroids. From a legislative point of view, all cosmetic products containing a prohibited whitening agent are illegal and must be taken off the EU market. A newly developed screening method using ultra high performance liquid chromatography-time off flight-mass spectrometry allows routine analysis of suspected products. 163 suspected skin whitening cosmetics, collected by Belgian inspectors at high risk sites such as airports and so-called ethnic cosmetic shops, were analyzed and 59% were classified as illegal. The whitening agents mostly detected were clobetasol propionate and hydroquinone, which represent a serious health risk when repeatedly and abundantly applied to the skin.

  18. Anatomically Plausible Surface Alignment and Reconstruction

    Paulsen, Rasmus R.; Larsen, Rasmus

    2010-01-01

    With the increasing clinical use of 3D surface scanners, there is a need for accurate and reliable algorithms that can produce anatomically plausible surfaces. In this paper, a combined method for surface alignment and reconstruction is proposed. It is based on an implicit surface representation...... combined with a Markov Random Field regularisation method. Conceptually, the method maintains an implicit ideal description of the sought surface. This implicit surface is iteratively updated by realigning the input point sets and Markov Random Field regularisation. The regularisation is based on a prior...... energy that has earlier proved to be particularly well suited for human surface scans. The method has been tested on full cranial scans of ten test subjects and on several scans of the outer human ear....

  1. Invariant visual object recognition: biologically plausible approaches.

    Science.gov (United States)

    Robinson, Leigh; Rolls, Edmund T

    2015-10-01

    Key properties of inferior temporal cortex neurons are described, and then, the biological plausibility of two leading approaches to invariant visual object recognition in the ventral visual system is assessed to investigate whether they account for these properties. Experiment 1 shows that VisNet performs object classification with random exemplars comparably to HMAX, except that the final layer C neurons of HMAX have a very non-sparse representation (unlike that in the brain) that provides little information in the single-neuron responses about the object class. Experiment 2 shows that VisNet forms invariant representations when trained with different views of each object, whereas HMAX performs poorly when assessed with a biologically plausible pattern association network, as HMAX has no mechanism to learn view invariance. Experiment 3 shows that VisNet neurons do not respond to scrambled images of faces, and thus encode shape information. HMAX neurons responded with similarly high rates to the unscrambled and scrambled faces, indicating that low-level features including texture may be relevant to HMAX performance. Experiment 4 shows that VisNet can learn to recognize objects even when the view provided by the object changes catastrophically as it transforms, whereas HMAX has no learning mechanism in its S-C hierarchy that provides for view-invariant learning. This highlights some requirements for the neurobiological mechanisms of high-level vision, and how some different approaches perform, in order to help understand the fundamental underlying principles of invariant visual object recognition in the ventral visual stream.

  2. Illegal use patterns, side effects, and analytical methods of ketamine.

    2016-11-01

    In Asian countries, such as China, Taiwan, and Hong Kong, ketamine (KT) is one of the most prevalent illicit use drugs. KT is regulated by various drug-related laws in many countries, such as Korea, Taiwan, China, U.S.A, Netherlands, UK, Australia, Mexico, and Canada. This review research explored pharmacology and side effects of KT, the illicit use patterns of KT, the analytical methods of KT in biological samples, and the concentrations of KT from abusers and non-abusers. Many side effects of KT have been reported mental and physical problems. Although many studies conducted various analytical methods for KT, this research focused on the urine and hair analysis and compared some parameters of samples, instruments, columns, extraction methods, internal standards, LOD/LOQ levels, metabolites, NK/K ratio, cut off values, and m/z values. Our research also compared the concentrations of KT in biological samples from abusers and non-abusers. Many rapid and precise analytical methods for illegal KT use are needed to be developed and applied to real samples. To minimize and prevent harm from KT, the authorities and appropriate agencies require a careful assessment, evaluation, early identification, and surveillance of KT users in both clinical and social settings. In addition, there is a need to construct a stricter legislative management and provide preventive education to younger individuals because illegal KT use is relatively common among the young populations.

  4. Plausibility and evidence: the case of homeopathy.

    Rutten, Lex; Mathie, Robert T; Fisher, Peter; Goossens, Maria; van Wassenhoven, Michel

    2013-08-01

    Homeopathy is controversial and hotly debated. The conclusions of systematic reviews of randomised controlled trials of homeopathy vary from 'comparable to conventional medicine' to 'no evidence of effects beyond placebo'. It is claimed that homeopathy conflicts with scientific laws and that homoeopaths reject the naturalistic outlook, but no evidence has been cited. We are homeopathic physicians and researchers who do not reject the scientific outlook; we believe that examination of the prior beliefs underlying this enduring stand-off can advance the debate. We show that interpretations of the same set of evidence--for homeopathy and for conventional medicine--can diverge. Prior disbelief in homeopathy is rooted in the perceived implausibility of any conceivable mechanism of action. Using the 'crossword analogy', we demonstrate that plausibility bias impedes assessment of the clinical evidence. Sweeping statements about the scientific impossibility of homeopathy are themselves unscientific: scientific statements must be precise and testable. There is growing evidence that homeopathic preparations can exert biological effects; due consideration of such research would reduce the influence of prior beliefs on the assessment of systematic review evidence.

  6. Health care and the illegal immigrant.

    Science.gov (United States)

    Glen, Patrick

    2013-01-01

    The question of whether illegal immigrants should be entitled to some form of health coverage in the United States sits at the intersection of two contentious debates: health reform and immigration reform. Proponents of extending coverage argue that the United States has a moral obligation to provide health care to all those within its borders. Conversely, those against doing so argue that immigrants illegally present in the country should not be entitled to public benefits. This Article seeks to chart a middle course between these extremes while answering two questions. First, does constitutional law mandate extending health coverage to illegal immigrants? Second, even if not legally mandated, are there compelling policy reasons for extending such coverage? This Article concludes that while health coverage for illegal immigrants is not required under prevailing constitutional norms, extending coverage as a matter of policy would serve the broader interests of the United States. Extending coverage would be beneficial as a matter of economics and public health, generating spillover benefits for all US citizens and those in the US healthcare and health insurance systems.

  11. The biomedicalisation of illegal abortion: the double life of misoprostol in Brazil

    Directory of Open Access Journals (Sweden)

    Silvia De Zordo

    Full Text Available Abstract This paper examines the double life of misoprostol in Brazil, where it is illegally used by women as an abortifacient and legally used in obstetric hospital wards. Based on my doctoral and post-doctoral anthropological research on contraception and abortion in Salvador, Bahia, this paper initially traces the “conversion” of misoprostol from a drug to treat ulcers to a self-administered abortifacient in Latin America, and its later conversion to aneclectic global obstetric tool. It then shows how, while reducing maternal mortality, its use as an illegal abortifacient has reinforced the double reproductive citizenship regime existing in countries with restrictive abortion laws and poor post-abortion care services, where poor women using it illegally are stigmatised, discriminated against and exposed to potentially severe health risks.

  14. Analytic Models of Plausible Gravitational Lens Potentials

    Energy Technology Data Exchange (ETDEWEB)

    Baltz, Edward A.; Marshall, Phil; Oguri, Masamune

    2007-05-04

    Gravitational lenses on galaxy scales are plausibly modeled as having ellipsoidal symmetry and a universal dark matter density profile, with a Sersic profile to describe the distribution of baryonic matter. Predicting all lensing effects requires knowledge of the total lens potential: in this work we give analytic forms for that of the above hybrid model. Emphasizing that complex lens potentials can be constructed from simpler components in linear combination, we provide a recipe for attaining elliptical symmetry in either projected mass or lens potential.We also provide analytic formulae for the lens potentials of Sersic profiles for integer and half-integer index. We then present formulae describing the gravitational lensing effects due to smoothly-truncated universal density profiles in cold dark matter model. For our isolated haloes the density profile falls off as radius to the minus fifth or seventh power beyond the tidal radius, functional forms that allow all orders of lens potential derivatives to be calculated analytically, while ensuring a non-divergent total mass. We show how the observables predicted by this profile differ from that of the original infinite-mass NFW profile. Expressions for the gravitational flexion are highlighted. We show how decreasing the tidal radius allows stripped haloes to be modeled, providing a framework for a fuller investigation of dark matter substructure in galaxies and clusters. Finally we remark on the need for finite mass halo profiles when doing cosmological ray-tracing simulations, and the need for readily-calculable higher order derivatives of the lens potential when studying catastrophes in strong lenses.

  15. Encoding the target or the plausible preview word? The nature of the plausibility preview benefit in reading Chinese.

    Science.gov (United States)

    Yang, Jinmian; Li, Nan; Wang, Suiping; Slattery, Timothy J; Rayner, Keith

    2014-01-01

    Previous studies have shown that a plausible preview word can facilitate the processing of a target word as compared to an implausible preview word (a plausibility preview benefit effect) when reading Chinese (Yang, Wang, Tong, & Rayner, 2012; Yang, 2013). Regarding the nature of this effect, it is possible that readers processed the meaning of the plausible preview word and did not actually encode the target word (given that the parafoveal preview word lies close to the fovea). The current experiment examined this possibility with three conditions wherein readers received a preview of a target word that was either (1) identical to the target word (identical preview), (2) a plausible continuation of the pre-target text, but the post-target text in the sentence was incompatible with it (initially plausible preview), or (3) not a plausible continuation of the pre-target text, nor compatible with the post-target text (implausible preview). Gaze durations on target words were longer in the initially plausible condition than the identical condition. Overall, the results showed a typical preview benefit, but also implied that readers did not encode the initially plausible preview. Also, a plausibility preview benefit was replicated: gaze durations were longer with implausible previews than the initially plausible ones. Furthermore, late eye movement measures did not reveal differences between the initially plausible and the implausible preview conditions, which argues against the possibility of misreading the plausible preview word as the target word. In sum, these results suggest that a plausible preview word provides benefit in processing the target word as compared to an implausible preview word, and this benefit is only present in early but not late eye movement measures.

    2016-01-01

    The occurrence of illegal medicines is a well-established global problem and concerns mostly small molecules. However, due to the advances in genomics and recombinant expression technologies there is an increased development of polypeptide therapeutics. Insulin is one of the best known polypeptide drug, and illegal versions of this medicine led to lethal incidents in the past. Therefore, it is crucial for the public health sector to develop reliable, efficient, cheap, unbiased and easily applicable active pharma-ceutical ingredient (API) identification and quantification strategies for routine analysis of suspected il-legal insulins. Here we demonstrate that our combined label-free full scan approach is not only able to distinguish between all those different versions of insulin and the insulins originating from different species, but also able to chromatographically separate human insulin and insulin lispro in conditions that are compatible with mass spectrometry (MS). Additionally, we were also able to selectively quantify the different insulins, including human insulin and insulin lispro according to the validation criteria, put forward by the United Nations (UN), for the analysis of seized illicit drugs. The proposed identification and quantification method is currently being used in our official medicines control laboratory to analyze insulins retrieved from the illegal market.

    2014-10-01

    Infant abandonment and infanticide are poorly understood in Malaysia. The information available in the public arena comes predominantly from anecdotal sources. The aim of this study was to describe the prevalence and characteristics of infanticide and illegal infant abandonment in Malaysia and to estimate annual rates for the most recent decade. Summaries of data about infanticide and illegal infant abandonment were gathered from police records; the annual number of live births was ascertained from the national registry. The estimated inferred infanticide rates for Malaysia were compared with the infanticide rates among countries of very high, high, medium, and low rankings on the Human Development, Gender Inequality, and Gini indices. From 1999 to 2011, 1,069 cases of illegal infant abandonment were recorded and 1,147 people were arrested as suspected perpetrators. The estimated inferred infanticide rate fluctuated between 4.82 and 9.11 per 100,000 live births, a moderate rate relative to the infanticide rates of other countries. There are substantial missing data, with details undocumented for about 78-87% of cases and suspected perpetrators. Of the documented cases, it appeared that more boys than girls were victims and that suspected perpetrators were predominantly Malays who were women, usually mothers of the victim; the possibility of arrest bias must be acknowledged. Economic and social inequality, particularly gender inequality, might contribute to the phenomena of infanticide and abandonment. Strategies to reduce rates of infanticide and illegal infant abandonment in Malaysia will require strengthening of the surveillance system and attention to the gender-based inequalities that underpin human development.

    Okolski, M

    2000-01-01

    Until the beginning of the 1990s Poland did not receive foreign migrants. Thereafter, the situation changed dramatically. A large part of the inflow proved to be illegal migrants, many of whom were in transit to Western Europe. Although these movements gradually declined in the second half of the decade, some became increasingly identified with relatively sophisticated smuggling of people. Foreigners smuggled from the South to the West, together with the international criminal networks assisting them, became typical of the migratory movements of people in Central and Eastern Europe during the 1990s. This article seeks to describe illegal migration from the perspective of Poland, a country often perceived as a major transit area in the smuggling of persons to Western Europe. The conclusions draw on the findings of several surveys recently carried out in Poland. Basic concepts related to illegal migration are defined and juxtaposed, and various myths and stereotypes concerning it that most often stem from the paucity of empirical evidence are examined. Finally, the trends observed in Poland are interpreted within the larger context of contemporary European migration.

    Full Text Available RESUMEN: La novela policíaca española reciente utiliza el contexto socio-político alrededor de la investigación que narra preocupándose más por la problemática humana que por la resolución del caso per se. Desde el fin de la dictadura hasta el comienzo del siglo XXI numerosos escritores han retratado el impacto del consumo de drogas ilegales y el narcotráfico en España. Este tipo de narrativa se dispone como un espacio para que implicados, víctimas e instituciones se pronuncien ante esta realidad y permite que se orqueste un discurso socialmente comprometido sobre la situación de estas sustancias. ABSTRACT: Recent Spanish detective novels have used the sociopolitical context surrounding the actual investigation narrated in the text in order to express a stronger concern about the issues in society than about the criminal case per se. Since the end of dictatorship until the beginning of twenty-first century, several authors have portrayed the impact of the consumption of and trafficking in illegal drugs in Spain. This kind of narrative lays a suitable ground for individuals, collectives and institutions involved with these substances to comment on this situation and to convey a socially committed discourse regarding this problem.

    opinions of a group of people about legal issues regarding addiction. Data collection was performed using a structured questionnaire with four themes. In order to participate, the individual could not use any drugs but should have a close relationship with a drug user. The data was processed using SPSS V. 14. There were 100 participants, 75% of whom were women, and 38% had a drug user as a friend, mainly cocaine and marijuana users. The participants had one opinion in common: laws should be more severe for people who use, sell, or transport drugs. The current laws do not improve consumers' criminal behavior. There is a need for further studies addressing people's opinion about this phenomenon in order to obtain a more realistic view of this drug issue.

    ências típicas da família nuclear.The problems related to use and abuse of legal and illegal drugs are considered worldwide epidemic. Although the drug use is considered an individual decision it is important to stress the role of the family in the conservation and changes of habits, custom and behaviours among family members and among generations. This study aimed to identify parents' discourses about legal and illegal drugs and to explore the divergences and agreements in their discourses. Method: The research was conducted through individual interviews with 13 university students at Bogotá. The interviews were analysed with the focus on systemic theory, constructivism and narrative analysis. In the results emerged the a the patriarchal culture context and expectance on the genre role, b three kinds of parents discourses that present divergences and agreements typical of the nuclear family.

Sessenta e quatro (12% notícias impressas apresentam histórias de vida de mulheres que abortaram com o misoprostol. As mulheres têm de 13 a 46 anos e sua inserção de classe demarca diferentes experiências de aborto. Três personagens foram identificados nos itinerários de aborto: amigas, intermediários e médicos. As histórias de aborto tardio são confundidas com a tipificação penal do infanticídio e são casos-limite para a narrativa midiática.This article analyzes how the Brazilian news media covers the illegal market for misoprostol, the main drug used to induce abortion. A total of 1,429 news stories were retrieved from 220 print and electronic media channels from 2004 to 2009. The analysis included 524 stories from 62 regional and national newspapers. Misoprostol appeared repeatedly in the news, but was usually approached from a criminal perspective, unlike abortion as a whole, which the Brazilian media routinely covers as a religious, political, and public health issue. Misoprostol is part of the illegal gender-related drug market, along with drugs for weight loss and erectile dysfunction and anabolic steroids. Sixty-four (12% of the news stories told life histories of women who had aborted with misoprostol. The women's ages ranged from 13 to 46 years, and

    Earthquakes in Turkey are frequently occurring disasters, causing much loss of life and property. It is tragic indeed that earthquakes should share the agenda with amnesty laws for illegal buildings. Illegal buildings are those constructed without authorization, legal bureaucratic sanction and, in most cases, without normal engineering control and checks. Buildings may become illegal for a variety of reasons. The very prospect of a waiver bill for illegal buildings spurs further illegal construction. The status of illegal buildings may legally change in time. What is an illegal building today may well be legal tomorrow under these circumstances. The present study deals with two different kinds of building: one is the framed building and the other has shear-wall frame. The capacity ratios, storey drifts and natural periods for the legally approved buildings and the effects of illegal or legal additional floors on these values are compared. It is determined that these buildings with illegal storeys should be strengthened and retrofitted by providing cast in-situ reinforced concrete shear walls.

    Rasch modeling and plausible values methodology were used to scale and report the results of the Organization for Economic Cooperation and Development's Programme for International Student Achievement (PISA). This article will describe the scaling approach adopted in PISA. In particular it will focus on the use of plausible values, a multiple imputation approach that is now commonly used in large-scale assessment. As with all imputation models the plausible values must be generated using models that are consistent with those used in subsequent data analysis. In the case of PISA the plausible value generation assumes a flat linear regression with all students' background variables collected through the international student questionnaire included as regressors. Further, like most linear models, homoscedasticity and normality of the conditional variance are assumed. This article will explore some of the implications of this approach. First, we will discuss the conditions under which the secondary analyses on variables not included in the model for generating the plausible values might be biased. Secondly, as plausible values were not drawn from a multi-level model, the article will explore the adequacy of the PISA procedures for estimating variance components when the data have a hierarchical structure.

    Full Text Available As a negative phenomenon, drug addiction appears already a big problem in modern world. Narcotic substances have affected the Republic of Macedonia and just like in other countries, every day users have increased. Today in the world of narcotics abuse has taken a big trend that has initiated a whole chain of criminality, which on one side has increased the number of drug addicts in the search for new amounts of narcotics, and in turn the desire of suppliers to realize the greater profits. Drugs are not the invention of modern man, it is certain that prehistoric people knew them too. The Republic of Macedonia is not a country distinct in the production of drugs, but it is a regional focal point for illegal trade of drugs known as the Balkan route. In this sense, main purpose of this paper is the analysis of statistical data of illegal trade with narcotic substances in Macedonia during 2005-2012.

    Illegal wildlife trade has reached alarming levels globally, extirpating populations of commercially valuable species. As a driver of biodiversity loss, quantifying illegal harvest is essential for conservation and sociopolitical affairs but notoriously difficult. Here we combine field-based carcass monitoring with fine-scale demographic data from an intensively studied wild African elephant population in Samburu, Kenya, to partition mortality into natural and illegal causes. We then expand our analytical framework to model illegal killing rates and population trends of elephants at regional and continental scales using carcass data collected by a Convention on International Trade in Endangered Species program. At the intensively monitored site, illegal killing increased markedly after 2008 and was correlated strongly with the local black market ivory price and increased seizures of ivory destined for China. More broadly, results from application to continental data indicated illegal killing levels were unsustainable for the species between 2010 and 2012, peaking to ∼ 8% in 2011 which extrapolates to ∼ 40,000 elephants illegally killed and a probable species reduction of ∼ 3% that year. Preliminary data from 2013 indicate overharvesting continued. In contrast to the rest of Africa, our analysis corroborates that Central African forest elephants experienced decline throughout the last decade. These results provide the most comprehensive assessment of illegal ivory harvest to date and confirm that current ivory consumption is not sustainable. Further, our approach provides a powerful basis to determine cryptic mortality and gain understanding of the demography of at-risk species.

  10. Some Remarks on the Model Theory of Epistemic Plausibility Models

    CERN Document Server

    Demey, Lorenz

    2010-01-01

    Classical logics of knowledge and belief are usually interpreted on Kripke models, for which a mathematically well-developed model theory is available. However, such models are inadequate to capture dynamic phenomena. Therefore, epistemic plausibility models have been introduced. Because these are much richer structures than Kripke models, they do not straightforwardly inherit the model-theoretical results of modal logic. Therefore, while epistemic plausibility structures are well-suited for modeling purposes, an extensive investigation of their model theory has been lacking so far. The aim of the present paper is to fill exactly this gap, by initiating a systematic exploration of the model theory of epistemic plausibility models. Like in 'ordinary' modal logic, the focus will be on the notion of bisimulation. We define various notions of bisimulations (parametrized by a language L) and show that L-bisimilarity implies L-equivalence. We prove a Hennesy-Milner type result, and also two undefinability results. ...

    2017-04-01

    We describe an experiment that explores the contribution of auditory and other features to the illusion of plausibility in a virtual environment that depicts the performance of a string quartet. 'Plausibility' refers to the component of presence that is the illusion that the perceived events in the virtual environment are really happening. The features studied were: Gaze (the musicians ignored the participant, the musicians sometimes looked towards and followed the participant's movements), Sound Spatialization (Mono, Stereo, Spatial), Auralization (no sound reflections, reflections corresponding to a room larger than the one perceived, reflections that exactly matched the virtual room), and Environment (no sound from outside of the room, birdsong and wind corresponding to the outside scene). We adopted the methodology based on color matching theory, where 20 participants were first able to assess their feeling of plausibility in the environment with each of the four features at their highest setting. Then five times participants started from a low setting on all features and were able to make transitions from one system configuration to another until they matched their original feeling of plausibility. From these transitions a Markov transition matrix was constructed, and also probabilities of a match conditional on feature configuration. The results show that Environment and Gaze were individually the most important factors influencing the level of plausibility. The highest probability transitions were to improve Environment and Gaze, and then Auralization and Spatialization. We present this work as both a contribution to the methodology of assessing presence without questionnaires, and showing how various aspects of a musical performance can influence plausibility.

    Sheridan, Robert; Mirabile, Jennifer; Hafler, Kristen

    2014-04-30

    In 2007 chicken jerky dog treats were implicated in causing illnesses and death in dogs in several countries. Affected dogs were diagnosed with acquired Fanconi syndrome, which is characterized by kidney malfunction. Known causes of this condition include a chemical assault by various contaminants including certain drugs. For this reason investigations into possible causes of the illnesses included antibiotics that may be used in animal husbandry. Targeted analyte screens of individual imported chicken jerky dog treats using LC-MS/MS detected six illegal antibiotics in imported products of several brands. Trimethoprim, tilmicosin, enrofloxacin, sulfaclozine, and sulfamethoxazole are not allowed in chicken at any level and were found as high as 2800 ng/g (ppb). Sulfaquinoxaline was found in chicken jerky treats as high as 800 ng/g, which is well above the U.S. FDA tolerance of 100 ng/g. Although there is no evidence these contaminants were responsible for the dog illnesses, their misuse could contribute to antibiotic-resistant strains of bacteria.

    1994-01-01

    "This paper develops a general equilibrium framework of a two-sector economy which incorporates illegal immigration in the presence of labor unions. It demonstrates that stricter enforcement of immigration laws, by reducing the demand for or supply of illegal aliens, benefits all legal workers in the economy. The model is used to evaluate the impact of these policy changes on national income. Results indicate that national income does not necessarily fall when immigration controls are tightened. The existence of a union mitigates the negative welfare impact of a reduction in the number of illegal immigrants."

    The author makes the case that the adoption of Proposition 187, the anti-illegal immigrant initiative, in California in 1994 was "an expression of public frustration with a government and civil society that seem out of touch and out of control, and with external convulsions that our borders can no longer contain." He suggests that the general public is increasingly concerned about the services provided to illegal aliens and their costs, and that responsible leadership should admit that illegal immigration, even at current levels, is not an unmitigated evil, and be prepared to set and enforce immigration limits.

  16. Classification using sparse representations: a biologically plausible approach.

    Spratling, M W

    2014-02-01

    Representing signals as linear combinations of basis vectors sparsely selected from an overcomplete dictionary has proven to be advantageous for many applications in pattern recognition, machine learning, signal processing, and computer vision. While this approach was originally inspired by insights into cortical information processing, biologically plausible approaches have been limited to exploring the functionality of early sensory processing in the brain, while more practical applications have employed non-biologically plausible sparse coding algorithms. Here, a biologically plausible algorithm is proposed that can be applied to practical problems. This algorithm is evaluated using standard benchmark tasks in the domain of pattern classification, and its performance is compared to a wide range of alternative algorithms that are widely used in signal and image processing. The results show that for the classification tasks performed here, the proposed method is competitive with the best of the alternative algorithms that have been evaluated. This demonstrates that classification using sparse representations can be performed in a neurally plausible manner, and hence, that this mechanism of classification might be exploited by the brain.

    2012-10-01

    Thousands of Americans are killed by gunfire each year, and hundreds of thousands more are injured or threatened with guns in robberies and assaults. The burden of gun violence in urban areas is particularly high. Critics suggest that the results of firearm trace data and gun trafficking investigation studies cannot be used to understand the illegal supply of guns to criminals and, therefore, that regulatory and enforcement efforts designed to disrupt illegal firearms markets are futile in addressing criminal access to firearms. In this paper, we present new data to address three key arguments used by skeptics to undermine research on illegal gun market dynamics. We find that criminals rely upon a diverse set of illegal diversion pathways to acquire guns, gun traffickers usually divert small numbers of guns, newer guns are diverted through close-to-retail diversions from legal firearms commerce, and that a diverse set of gun trafficking indicators are needed to identify and shut down gun trafficking pathways.

The objective of this paper is to describe the epidemiological characteristics of injuries among illegal migrants in Israel. The study was carried out retrospectively using data from 19 trauma centers that participated in the Israel National Trauma Registry between 1 January 2006 and 31 December 2011. Illegal migrants from Africa were compared to the local population. Migrants were injured more often than the local population from intentional injuries (57.11 %). Migrants were also less likely than the local population (58.38 %) to sustain a minor injury (i.e., injury severity ≤8). The study also shows the hospitalization cost as a result of injuries among migrants from Africa. Preventive measures among illegal migrants from Africa should prioritize intentional injuries and industrial site injuries.

    As the healthcare industry becomes more involved in joint venture activity, it must become more concerned with the possibility of illegal remuneration. Illegal remuneration, or the soliciting, receiving, offering, or paying of remuneration in return for the referral of patients or generation of business, is treated very seriously by HHS and the courts. Therefore, joint ventures must be constructed to avoid the danger areas as much as possible, or at least, minimize the risk.

    An ultra high performance liquid chromatography-tandem mass spectrometry method with modified QuEChERS procedure for sample preparation was developed for the simultaneous determination of 12 chemical drugs(chlorpheniramine,piroxicam,α-asarone etc)illegally added in herbal tea. The samples were extracted with acetonitrile,purified with QuEChERS procedure and filtrated by 0. 22 μm microporous filters. The separation was carried on an XBridge BEH C18 column(100 mm×2. 1 mm,3. 5 μm)by a gradient elution using acetonitrile/0. 1%( v/v)formic acid aqueous solution as mobile phases. The analytes were detected by tan-dem mass spectrometry with positive electrospray ionization( ESI+)in multiple reaction moni-toring( MRM)mode,and quantified by external standard calibration method. The correlation coefficients of the standard calibration curves for the 12 analytes were all above 0. 997. The lim-its of detection ranged from 0. 1 μg/L to 2. 1 μg/L,and the limits of quantification ranged from 0. 4 μg/L to 8. 0 μg/L. The average recoveries of the 12 analytes spiked at three levels in blank samples ranged from 62. 7% to 95. 2% with the RSDs from 1. 3% to 10. 8%. The samples bought from markets were screened,and some of the samples showed positive for these analytes. The method developed is easy to operate,sensitive,and with good purification effect. It can be applied to the rapid determination of the 12 chemical drugs illegally added in herbal tea.%建立了凉茶中马来酸氯苯那敏、吡罗昔康、α-细辛脑等12种非法添加的化学药物的 QuEChERS 结合超高效液相色谱-串联质谱( UPLC-MS/MS)的检测方法。样品经乙腈提取,应用 QuEChERS 技术净化,经0.22μm 微孔滤膜过滤后进行 UPLC-MS/MS 测定,以乙腈-0.1%( v/v)乙酸水溶液为流动相梯度洗脱,在 XBridge BEH C18柱(100 mm×2.1 mm,3.5μm)上实现12种化学药物的基线分离。该方法采用多反应监测(MRM)正离子模式扫描

    2016-01-01

    Good explanations for the unusual light curve of Boyajian's Star have been hard to find. Recent results by Montet & Simon lend strength and plausibility to the conclusion of Schaefer that in addition to short-term dimmings, the star also experiences large, secular decreases in brightness on decadal timescales. This, combined with a lack of long-wavelength excess in the star's spectral energy distribution, strongly constrains scenarios involving circumstellar material, including hypotheses invoking a spherical cloud of artifacts. We show that the timings of the deepest dimmings appear consistent with being randomly distributed, and that the star's reddening and narrow sodium absorption is consistent with the total, long-term dimming observed. Following Montet & Simon's encouragement to generate alternative hypotheses, we attempt to circumscribe the space of possible explanations with a range of plausibilities, including: a cloud in the outer solar system, structure in the ISM, natural and artificial ma...

    Maintaining an accurate mental representation of the current environment is crucial to detecting change in that environment and ensuring behavioral coherence. Past experience with interactions between objects, such as collisions, has been shown to influence the perception of object interactions. To assess whether mental representations of object interactions derived from experience influence the maintenance of a mental model of the current stimulus environment, we presented physically plausible and implausible collision events while recording brain electrical activity. The parietal P300 response to 'oddball' events was found to be modulated by the physical plausibility of the stimuli, suggesting that past experience of object interactions can influence working memory processes involved in monitoring ongoing changes to the environment.

    2013-12-01

    Full Text Available Abortion in Brazil provides public health impacts, mainly due to the high rate of maternal morbidity and mortality, because it most often occurs in an illegal practice and / or unsafe, because of the illegality of abortion in certain situations in the country. Therefore, it is an issue that refers to the various reflections, such as legal, moral, cultural, socio-economic and bioethical. Given the above, the study aims to address about abortion in Brazil and the impacts of illegality in public health. Study of literature review, descriptive and discursive, held in the database SciELO sites and governmental and non-governmental organizations. It was evident that the illegality of abortion in Brazil is harmful to the health of women who resort to unsafe practices and / or illegal, a violation of human rights, the women’s autonomy, as well as providing public health impacts, and sometimes this actually happens because the deficit in quality of care, specifically to sexual and reproductive health, as the actions of Family Planning. It is considered that the way of abortion in Brazil requires modifications, especially with regard to legislative and bioethics conflicts.

  11. Illegal Migration and Human Smuggling in Central and Eastern Europe

    Full Text Available The analytical and statistical services of border management organizations in Central and Eastern European countries have registered and accumulated a vast body of knowledge on the demographics and mechanisms of illegal migration over the last one-and-a-half decade. This paper attempts to tap this resource by summarising the results of a yearly survey among border guards of 17 countries. A set of quantitative indicators of illegal migration is developed, presented and interpreted, based on the answers of the border services to a series of quantitative and qualitative questions. This empirical material is used to evaluate the dynamics and pattern of illegal migration in Central and Eastern Europe on the one hand, and to examine the development of border management strategies on the other. The impacts of legal and institutional reforms are investigated in light of the temporal and spatial variations of border apprehension statistics. The interdependence of the two processes is reviewed from the point of view of national border management authorities, perhaps the most authoritative source of information on the issue. The results of the authors’ annual survey indicate that the progressive development of migration control mechanisms at national and international levels seems to have a significant impact on irregular migration flows as most indicators of illegal migration have significantly decreased after the turn of the century. At the same time, the geographical distribution of illegal migration flows in Central and Eastern European countries has become more complex over the years.

    With the prefectural governments' aid of the purchase, the Division of Pharmacognosy, Phytochemistry and Narcotics, National Institute of Health Sciences (NIHS) successively has surveyed illegal constituents in health food products implicitly advertizing tonic or slimming effect since the fiscal year of 2002 (slimming type) or 2003 (tonic type). The average numbers of the analyzed products per year are about 100 (slimming type) and 150 (tonic type), respectively. We also continuously distribute standards of authentic samples of several illegal components such as N-nitrosofenfluramine (NFF) and sildenafil (SIL) to prefectural institutes and the average gross number per year is about 140. In the case of slimming type, the fact that the products containing NFF were widely sold in Japanese markets in 2002 is well known. In addition, phenolphthalein, fenfluramine, sibtramine, desdimethylsibtramine, orlistat, mazindol, Rhubarb, Senna Leaf, etc. have been found as illegal constituents. In the tonic type products, we have identified more than 20 synthetic compounds relating to the erectile dysfunction (ED) treatment drugs, SIL, vardenafil and tadalafil (TDF). Since 2005, their synthetic intermediates and the patented but non-approved PDE5 inhibitors also have been found. It should be noted that TDF was found in the shells of capsule in 2009 and that mutaprodenafil was found as pro-drug type illegal component in 2010. In this report identification method of these illegal constituents is briefly described and then analytical trend in this decade is reviewed.

    In order to find out reasons for local government illegally occupying cultivated land and reduce such acts to ensure China’s grain security,this paper made an analysis through building the single person game model for local government’s legal or illegal occupation of cultivation land.It reached the conclusion that the benefit obtained by local government from illegal occupation of cultivated land is far greater than cost and punishment of such illegal acts.Illegal act is an optimal choice of local government to maximize its benefits,which is also the major reason for its illegal occupation of cultivated land.Thus,to reduce these illegal acts of local government,it should reduce benefits of local government obtained from illegal occupation of cultivated land,and increase costs for illegal occupation of cultivated land.

    Full Text Available Pilot assessment of illegal tobacco sales was conducted in Kazan city. The revealed law violations include placement of tobacco sales points within 100 meters around educational institutions, single cigarette sales and cigarette sales to minors. Single cigarettes were more likely to be sold in two of five types of sales outlets – pavilions and kiosks, those placed closer to educational institutions, and where larger part of the storefront was dedicated to cigarette packs. Points of sales with similar characteristics were more likely to sell to minors as well. Placement of notes regarding ban of cigarette sales to minors does not influence the levels of illegal sales. Measures to curb the levels of illegal cigarette sales were recommended. (Full text is in Russian

    The aims of this study are: to explore empirical clusters in a sample of individuals with a gambling disorder (GD) according to the presence of illegal behaviors, to describe the subgroups at a clinical level and to examine whether a temporal change has taken place across the last 9 years. The sample consisted of 378 patients with a GD who consecutively received outpatient treatment, and who reported the presence of the DSM-IV criteria "presence of illegal behavior". Two-step clustering procedure revealed the existence of four empirical groups, which differed in both sociodemographic and clinical profiles. The patients, who have committed illegal acts due to their gambling behavior, are a heterogeneous group in which it is possible to identify different subtypes, based on sociodemographic, psychopathological, clinical and personality characteristics.

    Radiography is a healthcare speciality with many technical challenges. Advances in engineering and information technology applications may continue to drive and be driven by radiographers. The world of diagnostic imaging is changing rapidly and radiographers must be proactive in order to survive. To ensure sustainable development, organisations have to identify future opportunities and threats in a timely manner and incorporate them into their strategic planning. Hence, the aim of this study was to analyse and describe plausible scenarios for the radiography profession in 2025. The study has a qualitative design with an inductive approach based on focus group interviews. The interviews were inspired by the Scenario-Planning method. Of the seven trends identified in a previous study, the radiographers considered two as the most uncertain scenarios that would have the greatest impact on the profession should they occur. These trends, labelled "Access to career advancement" and "A sufficient number of radiographers", were inserted into the scenario cross. The resulting four plausible future scenarios were: The happy radiographer, the specialist radiographer, the dying profession and the assembly line. It is suggested that "The dying profession" scenario could probably be turned in the opposite direction by facilitating career development opportunities for radiographers within the profession. Changing the direction would probably lead to a profession composed of "happy radiographers" who are specialists, proud of their profession and competent to carry out advanced tasks, in contrast to being solely occupied by "the assembly line".

    During the origin of life, the biological information of nucleic acid polymers must have increased to encode functional molecules (the RNA world). Ribozymes tend to be compositionally unbiased, as is the vast majority of possible sequence space. However, ribonucleotides vary greatly in synthetic yield, reactivity and degradation rate, and their non-enzymatic polymerization results in compositionally biased sequences. While natural selection could lead to complex sequences, molecules with some activity are required to begin this process. Was the emergence of compositionally diverse sequences a matter of chance, or could prebiotically plausible reactions counter chemical biases to increase the probability of finding a ribozyme? Our in silico simulations using a two-letter alphabet show that template-directed ligation and high concatenation rates counter compositional bias and shift the pool toward longer sequences, permitting greater exploration of sequence space and stable folding. We verified experimentally that unbiased DNA sequences are more efficient templates for ligation, thus increasing the compositional diversity of the pool. Our work suggests that prebiotically plausible chemical mechanisms of nucleic acid polymerization and ligation could predispose toward a diverse pool of longer, potentially structured molecules. Such mechanisms could have set the stage for the appearance of functional activity very early in the emergence of life.

    This is a report on the utility of a scale measuring attitudes toward illegal immigrants in two samples from nations that have more people moving out of the country than moving into the country. The Attitude toward Illegal Immigrants Scale was administered to 219 undergraduates from Sofia University in Bulgaria, and 179 undergraduates from Hanoi State University in Vietnam. Results yielded a scale with no sex differences, and acceptable alpha coefficients. Item analysis identified the most contributory and least contributory items, with considerable overlap in the two samples. A principal component analysis with varimax rotation was carried out to examine the structure.

    "We introduce a government budget constraint into an illegal immigration model, and show that the effect of increasing internal enforcement of immigration laws on the host country's disposable national income depends on the mix of employer fines and income taxation used to finance the added enforcement. These issues are addressed under alternative assumptions about (a) the ability of host country employers to discern between legal and illegal workers, and (b) host country labor market conditions. Empirical evidence for the United States indicates that the employer sanctions program may have had a negative impact on disposable national income."

  1. Neural networks, nativism, and the plausibility of constructivism.

    Science.gov (United States)

    Quartz, S R

    1993-09-01

    Recent interest in PDP (parallel distributed processing) models is due in part to the widely held belief that they challenge many of the assumptions of classical cognitive science. In the domain of language acquisition, for example, there has been much interest in the claim that PDP models might undermine nativism. Related arguments based on PDP learning have also been given against Fodor's anti-constructivist position--a position that has contributed to the widespread dismissal of constructivism. A limitation of many of the claims regarding PDP learning, however, is that the principles underlying this learning have not been rigorously characterized. In this paper, I examine PDP models from within the framework of Valiant's PAC (probably approximately correct) model of learning, now the dominant model in machine learning, and which applies naturally to neural network learning. From this perspective, I evaluate the implications of PDP models for nativism and Fodor's influential anti-constructivist position. In particular, I demonstrate that, contrary to a number of claims, PDP models are nativist in a robust sense. I also demonstrate that PDP models actually serve as a good illustration of Fodor's anti-constructivist position. While these results may at first suggest that neural network models in general are incapable of the sort of concept acquisition that is required to refute Fodor's anti-constructivist position, I suggest that there is an alternative form of neural network learning that demonstrates the plausibility of constructivism. This alternative form of learning is a natural interpretation of the constructivist position in terms of neural network learning, as it employs learning algorithms that incorporate the addition of structure in addition to weight modification schemes. By demonstrating that there is a natural and plausible interpretation of constructivism in terms of neural network learning, the position that nativism is the only plausible model of

    Rosen, Gail Emilia; Smith, Katherine F

    2010-08-01

    The global trade in illegal wildlife is a multi-billion dollar industry that threatens biodiversity and acts as a potential avenue for invasive species and disease spread. Despite the broad-sweeping implications of illegal wildlife sales, scientists have yet to describe the scope and scale of the trade. Here, we provide the most thorough and current description of the illegal wildlife trade using 12 years of seizure records compiled by TRAFFIC, the wildlife trade monitoring network. These records comprise 967 seizures including massive quantities of ivory, tiger skins, live reptiles, and other endangered wildlife and wildlife products. Most seizures originate in Southeast Asia, a recently identified hotspot for future emerging infectious diseases. To date, regulation and enforcement have been insufficient to effectively control the global trade in illegal wildlife at national and international scales. Effective control will require a multi-pronged approach including community-scale education and empowering local people to value wildlife, coordinated international regulation, and a greater allocation of national resources to on-the-ground enforcement.

    Full Text Available Abstract Background Illegal hunting is one of the major threats to vertebrate populations in tropical regions. This unsustainable practice has serious consequences not only for the target populations, but also for the dynamics and structure of tropical ecosystems. Generally, in cases of suspected illegal hunting, the only evidence available is pieces of meat, skin or bone. In these cases, species identification can only be reliably determined using molecular technologies. Here, we reported an investigative study of three cases of suspected wildlife poaching in which molecular biology techniques were employed to identify the hunted species from remains of meat. Findings By applying cytochrome b (cyt-b and cytochrome oxidase subunit I (COI molecular markers, the suspected illegal poaching was confirmed by the identification of three wild species, capybara (Hydrochoerus hydrochaeris, Chaco Chachalaca (Ortalis canicollis and Pampas deer (Ozotoceros bezoarticus. In Brazil, hunting is a criminal offense, and based on this evidence, the defendants were found guilty and punished with fines; they may still be sentenced to prison for a period of 6 to 12 months. Conclusions The genetic analysis used in this investigative study was suitable to diagnose the species killed and solve these criminal investigations. Molecular forensic techniques can therefore provide an important tool that enables local law enforcement agencies to apprehend illegal poachers.

  11. On the biological plausibility of Wind Turbine Syndrome.

    Science.gov (United States)

    Harrison, Robert V

    2015-01-01

    An emerging environmental health issue relates to potential ill-effects of wind turbine noise. There have been numerous suggestions that the low-frequency acoustic components in wind turbine signals can cause symptoms associated with vestibular system disorders, namely vertigo, nausea, and nystagmus. This constellation of symptoms has been labeled as Wind Turbine Syndrome, and has been identified in case studies of individuals living close to wind farms. This review discusses whether it is biologically plausible for the turbine noise to stimulate the vestibular parts of the inner ear and, by extension, cause Wind Turbine Syndrome. We consider the sound levels that can activate the semicircular canals or otolith end organs in normal subjects, as well as in those with preexisting conditions known to lower vestibular threshold to sound stimulation.

  12. Hamiltonian formulation of time-dependent plausible inference

    CERN Document Server

    Davis, Sergio

    2014-01-01

    Maximization of the path information entropy is a clear prescription for performing time-dependent plausible inference. Here it is shown that, following this prescription under the assumption of arbitrary instantaneous constraints on position and velocity, a Lagrangian emerges which determines the most probable trajectory. Deviations from the probability maximum can be consistently described as slices in time by a Hamiltonian, according to a nonlinear Langevin equation and its associated Fokker-Planck equation. The connections unveiled between the maximization of path entropy and the Langevin/Fokker-Planck equations imply that missing information about the phase space coordinate never decreases in time, a purely information-theoretical version of the Second Law of Thermodynamics. All of these results are independent of any physical assumptions, and thus valid for any generalized coordinate as a function of time, or any other parameter. This reinforces the view that the Second Law is a fundamental property of ...

In the current investigation, the purification of the ethanolic extract yielded nine new compounds, including N-acetylnorpandamarilactonines A (1) and B (2); pandalizines A (3) and B (4); pandanmenyamine (5); pandamarilactones 2 (6) and 3 (7), and 5(E)-pandamarilactonine-32 (8); and pandalactonine (9). The isolated alkaloids, with either a γ-alkylidene-α,β-unsaturated-γ-lactone or γ-alkylidene-α,β-unsaturated-γ-lactam system, can be classified into five skeletons including norpandamarilactonine, indolizinone, pandanamine, pandamarilactone, and pandamarilactonine. A plausible biosynthetic route toward 1-5, 7, and 9 is proposed.

    The emerging memristor-based neuromorphic engineering promises an efficient computing paradigm. However, the lack of both internal dynamics in the previous feedforward memristive networks and efficient learning algorithms in recurrent networks, fundamentally limits the learning ability of existing systems. In this work, we propose a framework to support complex learning functions by introducing dedicated learning algorithms to a bio-plausible recurrent memristive network with internal dynamics. We fabricate iron oxide memristor-based synapses, with well controllable plasticity and a wide dynamic range of excitatory/inhibitory connection weights, to build the network. To adaptively modify the synaptic weights, the comprehensive recursive least-squares (RLS) learning algorithm is introduced. Based on the proposed framework, the learning of various timing patterns and a complex spatiotemporal pattern of human motor is demonstrated. This work paves a new way to explore the brain-inspired complex learning in neuromorphic systems.

    Full Text Available Abstract Background Statistics on occupational accidents are based on data from registered employees. With the increasing number of immigrants employed illegally and/or without regular working visas in many developed countries, it is of interest to estimate the injury rate among such unregistered workers. Findings The current study was conducted in an area of North-Eastern Italy. The sources of information employed in the present study were the Accidents and Emergencies records of a hospital; the population data on foreign-born residents in the hospital catchment area (Health Care District 4, Primary Care Trust 20, Province of Verona, Veneto Region, North-Eastern Italy; and the estimated proportion of illegally employed workers in representative samples from the Province of Verona and the Veneto Region. Of the 419 A&E records collected between January and December 2004 among non European Union (non-EU immigrants, 146 aroused suspicion by reporting the home, rather than the workplace, as the site of the accident. These cases were the numerator of the rate. The number of illegally employed non-EU workers, denominator of the rate, was estimated according to different assumptions and ranged from between 537 to 1,338 individuals. The corresponding rates varied from 109.1 to 271.8 per 1,000 non-EU illegal employees, against 65 per 1,000 reported in Italy in 2004. Conclusions The results of this study suggest that there is an unrecorded burden of illegally employed immigrants suffering from work related injuries. Additional efforts for prevention of injuries in the workplace are required to decrease this number. It can be concluded that the Italian National Institute for the Insurance of Work Related Injuries (INAIL probably underestimates the incidence of these accidents in Italy.

Los resultados teórico-práctico propuestos y examinados se muestran como herramienta útil para evaluar, enriquecer y renovar la teoría sobre el líder y el desarrollo de liderazgo en las universidades frente a una sociedad globalizada.

  1. A perspective on SIDS pathogenesis. The hypotheses: plausibility and evidence

    Directory of Open Access Journals (Sweden)

    Goldwater Paul N

    2011-05-01

    Full Text Available Abstract Several theories of the underlying mechanisms of Sudden Infant Death Syndrome (SIDS have been proposed. These theories have born relatively narrow beach-head research programs attracting generous research funding sustained for many years at expense to the public purse. This perspective endeavors to critically examine the evidence and bases of these theories and determine their plausibility; and questions whether or not a safe and reasoned hypothesis lies at their foundation. The Opinion sets specific criteria by asking the following questions: 1. Does the hypothesis take into account the key pathological findings in SIDS? 2. Is the hypothesis congruent with the key epidemiological risk factors? 3. Does it link 1 and 2? Falling short of any one of these answers, by inference, would imply insufficient grounds for a sustainable hypothesis. Some of the hypotheses overlap, for instance, notional respiratory failure may encompass apnea, prone sleep position, and asphyxia which may be seen to be linked to co-sleeping. For the purposes of this paper, each element will be assessed on the above criteria.

  6. Transaction Costs: Prosecuting child trafficking for illegal adoption in Russia

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available As primary implementers of laws on human trafficking, law enforcement helps construct how these laws are understood and applied. This article examines how this process has unfolded in Russia by looking at the phenomenon of and debates surrounding child trafficking for illegal adoption. It argues that pre-existing experience with trafficking laws and cultural narratives surrounding adoption have led law enforcement to focus on uncovering evidence of monetary transactions rather than exploitation when prosecuting trafficking cases. This construction of the meaning of trafficking comes with important trade-offs. While the emphasis on transactions helps law enforcement to be successful at prosecuting cases involving selling children for illegal adoption, a focus on transactions rather than exploitation results in a de facto prosecution policy that ignores the many forms of exploitation that occur in other trafficking cases.

  8. Madagascar rosewood, illegal logging and the tropical timber trade

    Directory of Open Access Journals (Sweden)

    John L. Innes

    2010-06-01

    Full Text Available Although deforestation rates in the tropics are reportedly slowing, the loss of both forest area and forest quality remains a significant issue for many countries. This is particularly true of Madagascar, where recent government instability has enabled a significant increase in the incidence of illegal logging of Dalbergia species from National Parks such as Marojejy and Masoala. The logs are exported with relative ease as export permits are being made available. While attempts have been made to improve the management of tropical forests, in 2005, the International Tropical Timber Organization considered that only 7 % of tropical production forests were being managed sustainably. Given the challenges associated with halting illegal logging at source, emphasis has shifted to the control of the trade in forest products. The Convention on the International Trade in Endangered Species provides a mechanism to restrict such trade, but the Madagascan Dalbergia species are not listed. In the USA, the recent amendments to the ‘Lacey Act’ could provide a significant disincentive to the import of illegally logged wood products, but it remains to be seen whether this Act can be enforced effectively.

    Illegal immigration is a contentious issue on the American policy agenda. To understand the sources of public attitudes toward immigration, social scientists have focused attention on political factors such as party identification; they have also drawn on theories of intergroup contact to argue that contact with immigrants shapes immigration attitudes. Absent direct measures, contextual measures such as respondents' ethnic milieu or proximity to salient geographic features (such as borders) have been used as proxies of contact. Such a research strategy still leaves the question unanswered - is it contact or context that really matters? Further, which context, and for whom? This article evaluates the effects of party identification, personal contact with undocumented immigrants, and contextual measures (county Hispanic population and proximity to the US-Mexico border) on American attitudes toward illegal immigration. It finds that contextual factors moderate the effects of political party identification on attitudes toward illegal immigration; personal contact has no effect. These findings challenge the assumption that contextual measures act as proxies for interpersonal contact.

    Full Text Available Just as they do everywhere, illegal acts disturbing the peace and order of the social life also took place frequently in the Ottoman society. They occured in all residential areas ranging from the villages to the cities, and were committed either by individuals or people banded together. The state administration, taking the public complaints seriously and seeking solutions for the sake of communal peace, always stood against those involved personally or collectively in cases of cruelty, especially in those of seizure of goods and usurping of money, encroachment of estate or mansion, and aggressions against one’s life. In this study, we investigated the illegal acts that took place at Yabanabad district of Ankara in the 18th century, with regard to the information and related regulations contained in the archival records and the law registers, so as to see into which events of this period were considered unlawful, how the victimized people reacted to illegal assaults, how the state treated those involved in such crimes, and what sort of judicial proceedings were implemented in preventing these problems.

  11. The big crossing: illegal boat migrants in the Mediterranean.

    Kassar, Hassène; Dourgnon, Paul

    2014-08-01

    This article explores illegal migration routes and groups across North Africa to Europe. We describe sub-Saharan and cross-Mediterranean routes, and how they changed during the years. We propose an analytical framework for the main factors for these migrations, from local to international and regulatory context. We then describe sea-migrants' nationalities and socio-economic and demographic characteristics, from studies undertook in Tunisia and Morocco. While boat migration represents only a fraction of illegal migration to Europe, it raises humanitarian as well as ethical issues for European and North African (NA) countries, as a non-negligible amount of them end up in death tolls of shipwrecks in the Mediterranean Sea. Moreover, existing statistics show that illegal trans-Mediterranean migration is growing exponentially. Ongoing crises in Africa and the Middle East are likely to prompt even larger outflows of refugees in the near future. This should induce NA countries to share closer public policy concerns with European countries.

    Rice is the staple food for more than 50% of the world's population(1-3). Reliable prediction of changes in rice yield is thus central for maintaining global food security. This is an extraordinary challenge. Here, we compare the sensitivity of rice yield to temperature increase derived from field warming experiments and three modelling approaches: statistical models, local crop models and global gridded crop models. Field warming experiments produce a substantial rice yield loss under warming, with an average temperature sensitivity of -5.2 ± 1.4% K(-1). Local crop models give a similar sensitivity (-6.3 ± 0.4% K(-1)), but statistical and global gridded crop models both suggest less negative impacts of warming on yields (-0.8 ± 0.3% and -2.4 ± 3.7% K(-1), respectively). Using data from field warming experiments, we further propose a conditional probability approach to constrain the large range of global gridded crop model results for the future yield changes in response to warming by the end of the century (from -1.3% to -9.3% K(-1)). The constraint implies a more negative response to warming (-8.3 ± 1.4% K(-1)) and reduces the spread of the model ensemble by 33%. This yield reduction exceeds that estimated by the International Food Policy Research Institute assessment (-4.2 to -6.4% K(-1)) (ref. 4). Our study suggests that without CO2 fertilization, effective adaptation and genetic improvement, severe rice yield losses are plausible under intensive climate warming scenarios.

  13. A biologically plausible embodied model of action discovery

    Full Text Available During development, animals can spontaneously discover action-outcomepairings enabling subsequent achievement of their goals. We present abiologically plausible embodied model addressing key aspects of thisprocess. The biomimetic model core comprises the basal ganglia and itsloops through cortex and thalamus. We incorporate reinforcementlearning with phasic dopamine supplying a sensory prediction error,signalling 'surprising' outcomes. Phasic dopamine is used in acorticostriatal learning rule which is consistent with recent data. Wealso hypothesised that objects associated with surprising outcomesacquire 'novelty salience' contingent on the predicability of theoutcome. To test this idea we used a simple model of predictiongoverning the dynamics of novelty salience and phasic dopamine. Thetask of the virtual robotic agent mimicked an in vivo counterpart(Gancarz et al., 2011 and involved interaction with a target objectwhich caused a light flash, or a control object which did not.Learning took place according to two schedules. In one, the phasicoutcome was delivered after interaction with the target in anunpredictable way which emulated the in vivo protocol. Without noveltysalience, the model was unable to account for the experimental data.In the other schedule, the phasic outcome was reliably delivered andthe agent showed a rapid increase in the number of interactions withthe target which then decreased over subsequent sessions. We arguethis is precisely the kind of change in behaviour required torepeatedly present representations of context, action and outcome, toneural networks responsible for learning action-outcome contingency.The model also showed corticostriatal plasticity consistent withlearning a new action in basal ganglia. We conclude that actionlearning is underpinned by a complex interplay of plasticity andstimulus salience, and that our model contains many of the elementsfor biological action discovery to take place.

  14. Discursive Representations of Asylum Seekers and Illegal Immigrants in Ireland

    Directory of Open Access Journals (Sweden)

    Elaine Burroughs

    2013-12-01

    Full Text Available Migrants are often referred to as an all encompassing group of people and the “many faces of migration”, the variety of people, legalities and complexities involved, can be overlooked. The same can be said for non-EU migrants in the Irish context. Non-EU migrants (or those that are not Caucasian are generally viewed to be a distinct cohort of comparable migrants. Indeed, these migrants are often portrayed in a broadly negative way by key Irish institutions (such as the parliament or the media, and these representations impact upon how Irish society views non-EU migration and indeed migration in general. While Ireland is by no means the only European country in which this type of practice occurs, this paper aims to draw attention to generalized, inaccurate and misleading representations of non-EU migrants in Ireland, by specifically examining representations of asylum seekers and illegal immigrants. There can be an overlap in how these “types” of migrants are conceptualized and this paper therefore aims to develop an understanding of the implications involved for migrants categorized as an “asylum seeker” or an “illegal immigrant.” Furthermore, these topics are under-researched within the Irish context, yet they receive much political and public attention. At the same time however, this paper aims to challenge the labels assigned to non-EU migrants and the terminology that is used to define their identity so concretely. In the Irish context there is much confusion in relation to the multiple “faces” of non-EU migration, as a range of terminology is used to refer to them. This terminology is often used in an interchangeable manner, in an array of societal contexts. There is a consistent (whether this happens intentionally or unintentionally is debatable misuse of categories and migration terminology in Irish institutional discourses. Quite often those seeking asylum are referred to as illegal immigrants and vice versa

  15. Changing beliefs about implausible autobiographical events: a little plausibility goes a long way.

    Mazzoni, G A; Loftus, E F; Kirsch, I

    2001-03-01

    Three experiments investigated the malleability of perceived plausibility and the subjective likelihood of occurrence of plausible and implausible events among participants who had no recollection of experiencing them. In Experiment 1, a plausibility-enhancing manipulation (reading accounts of the occurrence of events) combined with a personalized suggestion increased the perceived plausibility of the implausible event, as well as participants' ratings of the likelihood that they had experienced it. Plausibility and likelihood ratings were uncorrelated. Subsequent studies showed that the plausibility manipulation alone was sufficient to increase likelihood ratings but only if the accounts that participants read were set in a contemporary context. These data suggest that false autobiographical beliefs can be induced in clinical and forensic contexts even for initially implausible events.

    2013-01-01

    Full Text Available The process of legalization and legitimization of discrimination of foreigners who are trying to reach some of the EU countries without appropriate permissions is the major topic of this text. It is shown how a legal and administrative qualification of a type of movement transforms into a social qualification of people who are undertaking that type of movement. To put it differently, the process of metaphoric transformations of the illegal movement to the illegal people is represented here. Once being done, these transformations allow further proliferation of ‘the illegal people’ to ‘criminals’ or ‘victims’, but they also can lead to the denial of all or some human characteristics to the people in question - dehumanization. When dehumanization is accepted at the level of representations, it begins to serve as the excuse for and justification of the aggressive practices towards the dehumanized people. This circular phenomenon of dehumanization is manifested systematically: it can be identified in the laws, the work of some state or international institutions, in everyday’s communication between the migrants and the people they meet. In the beginning of this text the migrations through the territory of Serbia and its asylum system have been presented. This is followed by the discussion of the dehumanization and the legislature and the legislative practices that support it. In the concluding part of the text dehumanization is presented as a linguistic, metaphoric, pragmatic and discursive phenomenon.

    This study aims to find an effective removal method of illegal parking bicycles based on the analysis on the numerical change of illegal bicycles. And then, we built the time and space quantitative distribution model of illegal parking bicycles after removal, considering the logistic increase of illegal parking bicycles, several behaviors concerning of direct return or indirect return to the original parking place and avoidance of the original parking place, based on the investigation of real condition of illegal bicycle parking at TENJIN area in FUKUOKA city. Moreover, we built the simulation model including above-mentioned model, and calculated the number of illegal parking bicycles when we change the removal frequency and the number of removal at one time. The next interesting four results were obtained. (1) Recovery speed from removal the illegal parking bicycles differs by each zone. (2) Thorough removal is effective to keep the number of illegal parking bicycles lower level. (3) Removal at one zone causes the increase of bicycles at other zones where the level of illegal parking is lower. (4) The relationship between effects and costs of removing the illegal parking bicycles was clarified.

    To assist in the efficient surveillance against illegal dumping, this study examined and evaluated two methods to illustrate the illegal dumping potential of sites using GIS (Geographic Information System) data. One approach focused on the occurrence of illegal dumping sites; the other on the size of the illegal dumping. Both approaches to zoning were implemented for the Kanto region of Japan, utilizing seven or eight major geographical attributes most closely related to illegal dumping. The zoning results revealed the areas requiring patrols against illegal dumping. Evaluation of the zoning results using the ROC (Receiver Operating Characteristic) curve showed the number of illegal dumping sites detectable under certain surveillance conditions and that the size-based zoning was superior, but this superiority was insignificant for revealing sites with higher potential for large illegal dumping, for which it would be sufficient to use the occurrence-based zoning. The evaluation also showed the contribution of each geographical attribute. Finally, application of the ROC curve to the surveillance planning process was examined, which enables the total social cost of pollution by illegal dumping, rehabilitation of dumping sites, and illegal dumping surveillance to be minimized.

    This study applied aspects of the Theory of Reasoned Action and the Prototype/Willingness model to understand cognitions associated with the use of illegal performance-enhancing substances. There were two study objectives. One was to investigate whether the illegal-is-effective heuristic (i.e. belief that illegal performance-enhancing substances are more effective than legal performance-enhancing substances) affects willingness to use illegal performance-enhancing substances. The second was to examine whether attitudes, norms, and prototypes influence the willingness and intentions to use illegal performance-enhancing substances. The illegal-is-effective heuristic was a significant predictor of willingness but was not a significant predictor of intentions. Implications for future research and prevention efforts are discussed.

  1. Games of corruption: how to suppress illegal logging.

    Corruption is one of the most serious obstacles for ecosystem management and biodiversity conservation. In particular, more than half of the loss of forested area in many tropical countries is due to illegal logging, with corruption implicated in a lack of enforcement. Here we study an evolutionary game model to analyze the illegal harvesting of forest trees, coupled with the corruption of rule enforcers. We consider several types of harvesters, who may or may not be committed towards supporting an enforcer service, and who may cooperate (log legally) or defect (log illegally). We also consider two types of rule enforcers, honest and corrupt: while honest enforcers fulfill their function, corrupt enforcers accept bribes from defecting harvesters and refrain from fining them. We report three key findings. First, in the absence of strategy exploration, the harvester-enforcer dynamics are bistable: one continuum of equilibria consists of defecting harvesters and a low fraction of honest enforcers, while another consists of cooperating harvesters and a high fraction of honest enforcers. Both continua attract nearby strategy mixtures. Second, even a small rate of strategy exploration removes this bistability, rendering one of the outcomes globally stable. It is the relative rate of exploration among enforcers that then determines whether most harvesters cooperate or defect and most enforcers are honest or corrupt, respectively. This suggests that the education of enforcers, causing their more frequent trialing of honest conduct, can be a potent means of curbing corruption. Third, if information on corrupt enforcers is available, and players react opportunistically to it, the domain of attraction of cooperative outcomes widens considerably. We conclude by discussing policy implications of our results. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The border and social policies that the United States shares with Mexico have had only a modest impact on the level of illegal immigration. Alternative methods could reduce the social backlash against Mexican immigrants in US states of destination. Federal Relief Aid to states affected by new arrivals would ameliorate hostility. Although economic stagnation may depress the flow of immigrants or job opportunities, legal or illegal, economic recovery is dependent on the hard work of immigrants. The political solution has been to tighten border controls. Other options are possible. There should be pressure placed on multilateral institutions such as the World Bank and the International Monetary Fund to incorporate immigration issues in economic policy decisions. Many market reforms have contributed to greater emigration. The US has the option to use both supply and demand side options. Enforcement of workplace rules on minimum wages and health and safety standards would make it more difficult to exploit immigrant workers and would decrease the incentive to hire illegal workers. In a deregulated market stricter work standards were considered difficult to attain. A 1993 opinion poll revealed that 65% thought immigration was not beneficial. Border apprehension rates have increased dramatically over the past 30 years. The most recent policies aim to encourage the mobility of capital and trade through the NAFTA free trade agreement while trying to discourage human resource mobility. The push factors in Mexico are identified as high levels of poverty and unemployment, overpopulation, and economic stagnation. NAFTA and prior economic development efforts have not addressed the push factors. Disruption of traditional ways and changes toward greater industrialization spur emigration. The US program to develop border export industry encouraged migration from the interior of Mexico to border areas. Recent Mexican policies have changed the incentives for small farmers to stay on

    The passage of electric current through the human body causes variable harm, ranging from loss of consciousness to death caused by paralysis of the bulbar nerve centers. This report describes a fatal case caused by an illegal fishing practice involving stunning fish with electric shocks produced by an electric generator carried through the water inside the carcass of an old refrigerator to keep it afloat. This occurrence is unusual because of the circumstances giving rise to the use of electric current and the cause of death, which resulted from the combination of the electric current produced by the generator and the saltwater, bringing about death by drowning.

  4. Militarization of the border and illegal immigration: Tamaulipas laborers

    Full Text Available Tamaulipas presents a long tradition of rural migration to the United States in search of farm employment. Until the eighties Tamaulipas’ undocumented workers crossed the border easily. However, from the nineties, as a result of a restrictive migration policy centered exclusively on the “supply–side” to cross the border has become intricate. As a result, most part of immigrants is using the services of “smuggles”. This paper analyses the impact of the militarization of the frontier on the emigration of Tamaulipas’ illegal rural workers seeking for farm jobs in the United States.

    Full Text Available PURPOSE: To monitor changes in habits in drug use among Italian high school students. METHODS: Cross-sectional European School Survey Project on Alcohol and Other Drugs (ESPAD carried out in Italy annually for 11 years (1999-2009 with representative samples of youth attending high school. The sample size considered ranges from 15,752 to 41,365 students and response rate ranged from 85.5% to 98.6%. Data were analyzed to obtain measures of life-time prevalence (LT, use in the last year (LY, use in the last 30 days (LM, frequent use. Comparisons utilized difference in proportion tests. Tests for linear trends in proportion were performed using the Royston p trend test. RESULTS: When the time-averaged value was considered, cannabis (30% LT was the most, and heroin the least (2% frequently used, with cocaine (5%, hallucinogens (2% and stimulants (2% in between. A clear gender gap is evident for all drugs, more obvious for hallucinogens (average M/F LY prevalence ratio 2, range 1.7-2.4, p<0.05, less for cannabis (average M/F LY prevalence ratio 1.3, range 1.2-1.5, p<0.05. Data shows a change in trend between 2005 and 2008; in 2006 the trend for cannabis use and availability dropped and the price rose, while from 2005 cocaine and stimulant use prevalence showed a substantial increase and the price went down. After 2008 use of all substances seems to have decreased. CONCLUSIONS: Drug use is widespread among students in Italy, with cannabis being the most and heroin the least prevalent. Girls are less vulnerable than boys to illegal drug use. In recent years, a decrease in heroin use is overbalanced by a marked rise in hallucinogen and stimulant use.

It has always existed and is associated with culture, in its historical and social context. The aim of this research is to know and analyze the perception of students from the Nursing School at the University of Guayaquil about legal and illegal drugs consumption. The methodological approach was qualitative, descriptive and exploratory. The sample consisted of eleven first-year students from the Nursing School. Individual and semi structured interviews were used for data collection. Thematic content analysis was adopted, in which five themes were identified: The economic situation, domestic violence, migration of close relatives, influence of the media that surround us, and ignorance about the topic. With a view to enhancing awareness on this hard reality that hurts and prejudices humanity, knowing students' perceptions contributes to identify their needs and create possibilities for health care interventions, particularly health promotion.

    2015-12-01

    Full Text Available This article analyses whether prostitution (illegal work and illegal immigrants have access to the protective ambits of statutory framework regulating employment relations. Its objective is to examine the scope of labour law, considerate of ever changing trends in the modern world of work. It utilizes the two notable precedents founded in Kylie v CCMA and Discovery Health v CCMA. This is considerate of inherent dynamics in contemporary labour relations where the majority of workers have been displaced into grey areas that offer little or no protection, thus rendering workers vulnerable to exploitation. The article highlights a rising tension arising out of exploitative labour practices and socio-economic factors, and the need for labour law to respond. It has been found that courts have creatively invented strategic methods that have successfully aided efforts of protecting vulnerable workers engaged in economic activities under precarious circumstances. This is to the extent that the Constitution, 1996 and the Labour Relations Act 66 of 1995 have been interpreted in a manner that enhances worker protection, which fulfils the purpose for which labour law was enacted.

    To control the rice production and farm usage in Taiwan, Agriculture and Food Agency (AFA) has published a series of policies to subsidize farmers to plant different crops or to practice fallow science 1983. Because of no efficient and examinable mechanism to verify the fallow fields surveyed by township office, illegal fallow fields were still repeated each year. In this research, we used remote sensing images, GIS data of Fields, and application records of fallow fields to establish an illegal fallow fields detecting method in Yulin County in central Taiwan. This method included: 1. collected multi-temporal images from FS-2 or SPOT series with 4 time periods; 2. combined the application records and GIS data of fields to verify the location of fallow fields; 3. conducted ground truth survey and classified images with ISODATA and Maximum Likelihood Classification (MLC); 4. defined the land cover type of fallow fields by zonal statistic; 5. verified accuracy with ground truth; 6. developed potential illegal fallow fields survey method and benefit estimation. We use 190 fallow fields with 127 legal and 63 illegal as ground truth and accuracies of illegal fallow field interpretation in producer and user are 71.43% and 38.46%. If township office surveyed 117 classified illegal fallow fields, 45 of 63 illegal fallow fields will be detected. By using our method, township office can save 38.42% of the manpower to detect illegal fallow fields and receive an examinable 71.43% producer accuracy.

  4. A computable general equilibrium assessment of the impact of illegal immigration on the Greek economy.

    Sarris, A H; Zografakis, S

    1999-01-01

    This paper presents a theoretical and empirical analysis of the impact of illegal immigrants on the small type economy of Greece by using the multisectoral computable general equilibrium model. The theoretical analysis utilizes a model showing that there is no equivocal case for illegal immigration leading to the decline in the real wages of unskilled labor and increases in the real wages of skilled labor. The empirical analysis uses an applied general equilibrium model for Greece, showing that the inflow of illegal immigrants has resulted in declines of the real disposable incomes of two classes of households, namely, those headed by an unskilled person, and those belonging to the poor and middle class income bracket. The results, on the other hand, showed that the large increase in the influx of illegal immigrants is macroeconomically beneficial, having significant adverse distribution implications when flexible wage adjustment is assumed in various labor markets. It appears that unskilled and hired agricultural workers are among those that are severely affected by the inflow of illegal workers. The results also appear to be fairly sensitive with respect to the elasticities of labor supply and demand, while they appear to be quite insensitive to the elasticity of substitution in import demand and export supply. Furthermore, it is also insensitive to the various parameters concerning the structure of the illegal labor market such as the amount of wage differential between illegal and domestic unskilled labor as well as the monetary amounts that illegal laborers remit abroad.

    Full Text Available Illegal dumping is dumping of any waste such as oil, furniture, appliances, trash, litter or landscaping cuttings, upon any land of state, city, village or private ownership without consent of the owner. Illegal dumping has a great negative and fatal impact on our environment and all living organisms both fauna and flora. It also exposes people to various risks of chemicals (fluids or dust and is a big threat to all under-ground and surface water resources. Illegal dumps also attract all kinds of bugs such as rodents and insects. For example, illegal dumps with waste tires provide a practically perfect place for mosquitoes to breed. Mosquitoes can multiply 100 times faster than normal in the warm, stagnant water in waste tires. Exemplary for the illegal dump in Sverdlovo of Leningrad Oblast’ the main purpose of this article is to offer a possible option for the remediation of contaminated area.

    Harrelson, Megan E; Alexander, Apryl A; Morais, Hugo B; Burkhart, Barry R

    2017-07-01

    The current study examined the relationship among self-disclosure of illegal sexual behaviors and two conceptually relevant constructs in psychotherapy: childhood polyvictimization (i.e., cumulative types of victimization experienced during childhood) and caregiver attachment. Participants consisted of 63 adolescent males participating in mandated treatment for illegal sexual behavior. Childhood polyvictimization and caregiver attachment were expected to predict self-disclosure of illegal sexual behaviors. Quality of caregiver attachment was also expected to mediate the relationship between polyvictimization and disclosure. Consistent with our main hypothesis, results indicate that quality of caregiver attachment mediated the relationship between childhood polyvictimization and self-disclosure of illegal sexual behaviors in psychotherapy. The current findings highlight the impact of polyvictimization on important therapeutic processes as well as the importance of assessing for multiple types of victimization in adolescents who engage in illegal sexual behavior. Further clinical implications regarding the use of trauma-informed approaches during sex offender treatment are discussed.

  11. Illegal and Unsustainable Wildlife Hunting and Trade in Mongolia

    Peter Zahler

    2004-12-01

    Full Text Available Recent reports and studies document dramatic declines in a wide variety of wildlife species in Mongolia. The prime driver in these declines appears to be illegal and unsustainable hunting, both for local trade and consumption and for the international market. While data on these declines are sparse, comparisons of survey reports since the 1980s present evidence that some species may have declined by up to 90% in recent years. We outline the situation for eight major species of wildlife in Mongolia (saiga antelope, Mongolian gazelle, red deer , musk deer , ar gali, brown bear , Siberian marmot, and saker falcon. We then review the existing legal conditions and government efforts to control this situation, and suggest specific changes and actions that Mongolia should take to halt these dramatic declines in wildlife populations and avoid what may soon become an extinction crisis.

    Full Text Available The main focus of this paper lies in explaining the hypothesis that the exclusion of the (illegal Bangladeshi immigrants in Assam has been the outcome of a continuous historical process undertaken by the political leaders of the state, rather than as a result of any particular mass uprising from ‘below’. This push from a top-down perspective changed the issue from one of economic consequences to a more religious nature, also culminating in a failed project to assert a unique indigenous ‘Assamese’ identity in relation to the ‘other’, all the while relegating the more usual aspects of open versus closed borders that figure in immigration discourses to the background.

  17. [Abortion in unsafe conditions. Concealment, illegality, corruption and negligence].

    Science.gov (United States)

    Ortiz Ortega, A

    1993-01-01

    "Abortion practiced under conditions of risk" is a phrase used to refer to illegal abortion. The phrase does not highlight the disappearance of risk when legislation changes. Rather, it calls attention to the fact that legal restrictions significantly increase dangers while failing to discourage women determined to terminate pregnancies. The International Planned Parenthood Federation defines abortion under conditions of risk as the use of nonoptimal technology, lack of counseling and services to orient the woman's decision and provide postabortion counseling, and the limitation of freedom to make the decision. The phrase encompasses concealment, illegality, corruption, and negligence. It is designed to impose a reproductive health perspective in response to an unresolved social conflict. Steps have been developed to improve the situation of women undergoing abortion even without a change in its legal status. Such steps include training and purchase of equipment for treatment of incomplete abortions and development of counseling and family planning services. The central difficulty of abortion induced in conditions of risk derives from the laws imposing the need for secrecy. In Mexico, the abortion decision belongs to the government and the society, while individual absorb the consequences of the practice of abortion. Public decision making about abortion is dominated by the concept that the female has an obligation to carry any pregnancy to term. Women who interfere with male descendency and practice a sexuality distinct from reproduction are made to pay a price in health and emotional balance. Resolution of the problem of abortion will require new concepts in terms of legal status, public health issues, and the rights of women.

  1. Exploring apposite therapeutic target for apoptosis in filarial parasite: a plausible hypothesis.

    Human lymphatic filariasis is a parasitic disease with profound socioeconomic encumbrance owing to its associated disability, affecting predominantly but not limited to the developing nations of tropics and subtropics. There are several technical issues like poor therapeutic and preventive repertoire as well as administrative and infrastructural limitations which jeopardize the salvage measures and further complicate the plight. Therefore, considering the gravity of the problem, WHO has mandated (under tropical disease research scheme) for placing emphasis on validation of novel therapeutic targets against this disease with the unfortunate tag of 'neglected tropical disease'. However, dearth of knowledge of parasite biology viciously coupled with difficulty of access to parasitic material from suitable animal model along with growing cost burden of high end research poses formidable challenge. Based on the recent research evidences, here we propose a premise with targeted apoptotic impact as a novel rationale to be exploited towards anti-parasitic drug development. The new era of bioinformatics ushers in new optimism with a wide range of genomic and proteomic database in public domain. Such platform might offer wonders for drug research, but needs highly selective criterion specificity. In order to test our hypothesis presumptively, we deployed a scheme for identification of target proteins from filarial parasitic origin through wide database search with precise criteria of non-homology against the host along with functional essentiality for the parasite. Further screening for proteins with growth potential from such list of essential non-homologous proteins was undertaken to mine out suitable representative target for ensuing apoptotic impact though effective inhibitors. A unique protein enzyme, RNA dependent RNA polymerase, which besides its vital role in RNA virus is believed to have regulatory role in gene expression, emerged as a plausible target. This protein

    The informativity of a computational model of language acquisition is directly related to how closely it approximates the actual acquisition task, sometimes referred to as the model's cognitive plausibility. We suggest that though every computational model necessarily idealizes the modeled task, an informative language acquisition model can aim to be cognitively plausible in multiple ways. We discuss these cognitive plausibility checkpoints generally and then apply them to a case study in word segmentation, investigating a promising Bayesian segmentation strategy. We incorporate cognitive plausibility by using an age-appropriate unit of perceptual representation, evaluating the model output in terms of its utility, and incorporating cognitive constraints into the inference process. Our more cognitively plausible model shows a beneficial effect of cognitive constraints on segmentation performance. One interpretation of this effect is as a synergy between the naive theories of language structure that infants may have and the cognitive constraints that limit the fidelity of their inference processes, where less accurate inference approximations are better when the underlying assumptions about how words are generated are less accurate. More generally, these results highlight the utility of incorporating cognitive plausibility more fully into computational models of language acquisition.

  6. Using critical evaluation to reappraise plausibility judgments: A critical cognitive component of conceptual change

    Science.gov (United States)

    Lombardi, D.

    2011-12-01

    Plausibility judgments-although well represented in conceptual change theories (see, for example, Chi, 2005; diSessa, 1993; Dole & Sinatra, 1998; Posner et al., 1982)-have received little empirical attention until our recent work investigating teachers' and students' understanding of and perceptions about human-induced climate change (Lombardi & Sinatra, 2010, 2011). In our first study with undergraduate students, we found that greater plausibility perceptions of human-induced climate accounted for significantly greater understanding of weather and climate distinctions after instruction, even after accounting for students' prior knowledge (Lombardi & Sinatra, 2010). In a follow-up study with inservice science and preservice elementary teachers, we showed that anger about the topic of climate change and teaching about climate change was significantly related to implausible perceptions about human-induced climate change (Lombardi & Sinatra, 2011). Results from our recent studies helped to inform our development of a model of the role of plausibility judgments in conceptual change situations. The model applies to situations involving cognitive dissonance, where background knowledge conflicts with an incoming message. In such situations, we define plausibility as a judgment on the relative potential truthfulness of incoming information compared to one's existing mental representations (Rescher, 1976). Students may not consciously think when making plausibility judgments, expending only minimal mental effort in what is referred to as an automatic cognitive process (Stanovich, 2009). However, well-designed instruction could facilitate students' reappraisal of plausibility judgments in more effortful and conscious cognitive processing. Critical evaluation specifically may be one effective method to promote plausibility reappraisal in a classroom setting (Lombardi & Sinatra, in progress). In science education, critical evaluation involves the analysis of how evidentiary

  7. Toward a new understanding of the links between poverty and illegal wildlife hunting.

    Conservation organizations have increasingly raised concerns about escalating rates of illegal hunting and trade in wildlife. Previous studies have concluded that people hunt illegally because they are financially poor or lack alternative livelihood strategies. However, there has been little attempt to develop a richer understanding of the motivations behind contemporary illegal wildlife hunting. As a first step, we reviewed the academic and policy literatures on poaching and illegal wildlife use and considered the meanings of poverty and the relative importance of structure and individual agency. We placed motivations for illegal wildlife hunting within the context of the complex history of how wildlife laws were initially designed and enforced to indicate how hunting practices by specific communities were criminalized. We also considered the nature of poverty and the reasons for economic deprivation in particular communities to indicate how particular understandings of poverty as material deprivation ultimately shape approaches to illegal wildlife hunting. We found there is a need for a much better understanding of what poverty is and what motivates people to hunt illegally.

  8. The net national costs of illegal immigration into the United States.

    1995-04-01

    "This article examines the major economic pros and cons of illegal immigration and answers the question: what, if any, are the public and private costs of illegal immigration in the United States? In brief, the article finds that between four and 5.4 million illegal immigrants reside here.... The article also finds that illegal immigrants and their own citizen children cost taxpayers an additional $12 to $16.2 billion annually for education, public services, and incarceration after deducting all local, state, and federal taxes paid in by them. In the private sector, illegal aliens are found to save their employers and owners of capital about $1.5 billion more than U.S. workers lose due to wage depression. The article also considers what legal and enforcement reforms would be necessary to dramatically slow the current flow of 300,000 illegals yearly and concludes that, although improvements in the system are now being proposed, the actual reforms will be insufficient to more than stem the currently rising tide of illegals due to economic instability in Mexico and the Third World."

    Several studies have shown activation of the mirror neuron system (MNS), comprising the temporal, posterior parietal, and sensorimotor areas when observing plausible actions, but far less is known on how these cortical areas interact during the recognition of a plausible action. Here, we recorded neural activity with magnetoencephalography while subjects viewed point-light displays of biologically plausible and scrambled versions of actions. We were interested in modulations of oscillatory activity and, specifically, in coupling of oscillatory activity between visual and motor areas. Both plausible and scrambled actions elicited modulations of θ (5-7 Hz), α (7-13 Hz), β (13-35 Hz), and γ (55-100 Hz) power within visual and motor areas. When comparing between the two actions, we observed sequential and spatially distinct increases of γ (∼65 Hz), β (∼25 Hz), and α (∼11 Hz) power between 0.5 and 1.3 s in parieto-occipital, sensorimotor, and left temporal areas. In addition, significant clusters of γ (∼65 Hz) and α/β (∼15 Hz) power decrease were observed in right temporal and parieto-occipital areas between 1.3 and 2.0 s. We found β-power in sensorimotor areas to be positively correlated on a trial-by-trial basis with parieto-occipital γ and left temporal α-power for the plausible but not for the scrambled condition. These results provide new insights in the neuronal oscillatory activity of the areas involved in the recognition of plausible action movements and their interaction. The power correlations between specific areas underscore the importance of interactions between visual and motor areas of the MNS during the recognition of a plausible action.

The study activities carried out at Jejangkit Pasar Village, Jejangkit District, Barito Kuala Regency, South Kalimantan, with the object of research of Pokmaswas Berkat Bersama. The data collected were data sourced directly from the observation in the study location and other supporting data related to the study object. Data analyzed with descriptive and paired t – test to compare the capture production before and after illegal fishing.  The results showed that Barito Kuala regency had facilities that were intended for fish resource monitoring through patrols, conducting enforcement by regulatory authorities for fisheries, socialization of surveillance system of society based (SISWASMAS but violations still occurred so that they gave the impression of ineffectiveness or not optimal surveillance activities undertaken in the prevention and treatment of illegal fishing, due to the lack of public understanding factors as well as economy factors. The level of participation of fishermen of Pokmaswas Berkat Bersama in the supervision of fishery resources was quite high, judging from the attitude of fishermen of Pokmaswas Berkat Bersama who mostly reported to the supervising apparatus when they saw illegal fishing activities, rebuked and advised, and ever discussed the issue of illegal fishing with their friends and were willing if they are involved in a meeting that discussed the illegal fishing. Results of the statistical analysis showed highly significant differences in capture production between before and after the occurrence of illegal fishing, where the fishermen average capture production of Pokmaswas

    This study sought to understand the factors associated with street racing among the illegal motorcycle racers in Malaysia or known as the "Mat Rempit". Street outreach interviewer-administered surveys were conducted from June 2008 to January 2009 in this multi-state study. A total of 2022 participants were surveyed, the mean ± SD age of the participants was 20.5 ± 3.4 years (age range: 12 to 35 years). Mean duration of street racing was 2.65(SD ± 1.77) years (range: 2 months to 12 years), with 50.1% and 35.8% reporting stunt riding and alcohol drinking while racing, respectively. With regard to risk behaviours, cigarette smoking was highly prevalent among the study participants (78.3%), followed by alcohol drinking (27.8%) and recreational drug use (18.8%). Participants scored high on the masculinity scale (15.7 ± 4.0 out of 21.0). The results of the logistic regression analysis showed that socio-demographic variables, risk behaviour and masculinity scores were associated with racing frequency. Given these associations, tailoring family-centered interventions to the needs of the lower socio-economic groups and interventions recognizing the negative consequences of health risk behaviours related to street racing as an expression of traditional masculinity should be emphasized.

    2012-08-01

    Full Text Available Illegal logging is perceived to pose significant obstacles to the achievement of sustainable management of forests in the tropics. Equally importantly, it gives rise to or supports other undesirable outcomes – networks of corruption, generating significant volumes of “black” money and fuelling speculation, crime, or trafficking. However, illegal logging of tropical timber is not homogeneous and its characteristics depend, among others, on the supplying markets, at the national or the international scales. Available approaches to reduce illegal logging, at different levels of governance, in the producing and consuming countries are reviewed and their potential contribution is assessed.

After an intense lobbying effort by the business community, most provisions relating to legal immigration were omitted from the final bill. Instead, the 1996 Act focuses on illegal immigration reform and includes some of the toughest measures ever taken against illegal immigration." Aspects considered include border enforcement, penalities against alien smuggling and document fraud, deportation and exclusion proceedings, employer sanctions, welfare provisions, and changes to existing refugee and asylum procedures.

    This research examined the possibility of developing Mokken cumulative scales measuring attitudes toward illegal immigrants in a 9-nation sample. A total of 1,407 respondents primarily from national and regional universities participated in the surveys including the 20-item Illegal Immigration Scale. The scales displayed acceptable reliability with coefficients alpha ranging from .79 to .93. A Procrustes analysis yielded coefficients of congruence with the previously established three-factor solution. The amount of variance accounted for varied between 33.1 and 54.7%, supporting the presence of other factors in attitudes toward illegal immigrants. Mokken scale analysis yielded robust and economical scales in two clusters of national samples.

    Cox, William T L; Devine, Patricia G

    2014-02-01

    In the present study, participants administered painful electric shocks to an unseen male opponent who was either explicitly labeled as gay or stereotypically implied to be gay. Identifying the opponent with a gay-stereotypic attribute produced a situation in which the target's group status was privately inferred but plausibly deniable to others. To test the plausible deniability hypothesis, we examined aggression levels as a function of internal (personal) and external (social) motivation to respond without prejudice. Whether plausible deniability was present or absent, participants high in internal motivation aggressed at low levels, and participants low in both internal and external motivation aggressed at high levels. The behavior of participants low in internal and high in external motivation, however, depended on experimental condition. They aggressed at low levels when observers could plausibly attribute their behavior to prejudice and aggressed at high levels when the situation granted plausible deniability. This work has implications for both obstacles to and potential avenues for prejudice-reduction efforts.

    The growing complexity and global nature of wildlife poaching threaten the survival of many species worldwide and are outpacing conservation efforts. Here, we reviewed proximal and distal factors, both social and ecological, driving illegal killing or poaching of large carnivores at sites where it can potentially occur. Through this review, we developed a conceptual social-ecological system framework that ties together many of the factors influencing large carnivore poaching. Unlike most conservation action models, an important attribute of our framework is the integration of multiple factors related to both human motivations and animal vulnerability into feedbacks. We apply our framework to two case studies, tigers in Laos and wolverines in northern Sweden, to demonstrate its utility in disentangling some of the complex features of carnivore poaching that may have hindered effective responses to the current poaching crisis. Our framework offers a common platform to help guide future research on wildlife poaching feedbacks, which has hitherto been lacking, in order to effectively inform policy making and enforcement.

As a result, the FAO adopted anInternational Plan of Action in 2001 which called upon all its members to take actions against these illegal practices.The EC adopted a Regulation to prevent, deter and eliminate IUU fishing on 29 September 2008. It will enter intoforce on 1 January 2010 and is inspired by the FAOs International Plan of Action to prevent, deter and eliminate IUUfishing (2001. The Proposal for a Regulation to fight IUU fishing was a result from a public consultation held inJanuary 2007. It constitutes one of the most serious threats to the sustainable exploitation of living aquatic resourcesand marine biodiversity, causes depletion of fish stocks and future stock growth, damages the marine environment byover fishing and irresponsible fishing practices and techniques. The depletion of fish stocks reduces the size ofcatches which in turn contributes to lower turnover and eventually job losses. It contributes to unfair competitionamong those operators who abide by the rules and those who do not and it causes serious overall consequences forcoastal communities and in particular those in developing countries who rely to a large extent on fisheries

    We present a framework for automated planning based on plausibility models, as well as algorithms for computing plans in this framework. Our plausibility models include postconditions, as ontic effects are essential for most planning purposes. The framework presented extends a previously developed...... framework based on dynamic epistemic logic (DEL), without plausibilities/beliefs. In the pure epistemic framework, one can distinguish between strong and weak epistemic plans for achieving some, possibly epistemic, goal. By taking all possible outcomes of actions into account, a strong plan guarantees...... that the agent achieves this goal. Conversely, a weak plan promises only the possibility of leading to the goal. In real-life planning scenarios where the planning agent is faced with a high degree of uncertainty and an almost endless number of possible exogenous events, strong epistemic planning...

  9. Inference and Plausible Reasoning in a Natural Language Understanding System Based on Object-Oriented Semantics

    CERN Document Server

    Ostapov, Yuriy

    2012-01-01

    Algorithms of inference in a computer system oriented to input and semantic processing of text information are presented. Such inference is necessary for logical questions when the direct comparison of objects from a question and database can not give a result. The following classes of problems are considered: a check of hypotheses for persons and non-typical actions, the determination of persons and circumstances for non-typical actions, planning actions, the determination of event cause and state of persons. To form an answer both deduction and plausible reasoning are used. As a knowledge domain under consideration is social behavior of persons, plausible reasoning is based on laws of social psychology. Proposed algorithms of inference and plausible reasoning can be realized in computer systems closely connected with text processing (criminology, operation of business, medicine, document systems).

These intervals should ideally be determined based on biologic plausibility considering features of the AEFI, presumed or known pathologic mechanism, and the vaccine. Misspecification of the length and timing of these intervals may result in introducing bias in epidemiologic and clinical studies of immunization safety. To date, little work has been done to formally assess and determine biologically plausible and evidence-based risk intervals in immunization safety research. In this report, we present a systematic process to define biologically plausible and evidence-based risk interval estimates for two specific AEFIs, febrile seizures and acute disseminated encephalomyelitis. In addition, we review methodologic issues related to the determination of risk intervals for consideration in future studies of immunization safety.

  11. The semiosis of prayer and the creation of plausible fictional worlds

    Full Text Available Prayer and incantation can perhaps be said to be 'mechanisms' that promise that lack will be liquidated and that there is an unlimited signator, a father, or some other metaphysical creature, standing behind and legitimizing the discourse. A way of communicating with the Unlimited that is privileged by an interpretive community that read the prayers aloud and enacted the magical stage-scripts. These highly overlapping categories function as one of the most common subforms of religious discourse for the creation, actualization and maintenance of plausible fictional worlds. They are liminal and transitional mechanisms that manipulate an empirical reader to phase-shift from an actual world to a plausible, by being inscribed in a possible and fictional world, thus creating a model reader, that perceives and acts according to the plausible world outlined by a given interpretive community, and that hears god talking in voces magicae and in god-speaking silence.

    Full Text Available This study aimed to describe the shape of local government actions in tackling illegal fishing in Aceh, the handling of illegal fishing destructive fishery resources. The fundamental point is Law No. 45 Year 2009 concerning fisheries. This spesification of this research descriptive analysis, used both normative juridical approach and empirical. The results showed that the local government has made an effort preventive and repressive in the case of illegal fishing. To coordinate with relevant agencies and empower the role of traditional institutions of the sea to assist the role of government and law enforcement.Local governments should improve the coordination and supervision of the marine area, to monitor and evaluate the performance of local authorities in applying the law against this illegal fishing case.

  14. Illegal private clinics: ideal health services choices among rural-urban migrants in China?

    The main purpose of this article is to explore the important issues and the role of illegal private clinics in health services access among rural-urban migrants in China. The function that illegal private clinics substantially play on the health among rural-urban migrants in China is rarely discussed in studies. A study on a migrant community in Beijing shows the disadvantaged status of health services choices and the constraints for access to health services among migrants. It argues that the existence of illegal private clinics provides a channel to migrants for medical services in the city and reflects the difficulties and high cost of providing medical services to migrants in urban public hospitals. Occasionally the illegal private clinics can cause danger to the health of migrants.

    Cosmetic products containing illegal whitening agents are still found on the European market. They represent a considerable risk to public health, since they are often characterised by severe side effects when used chronically. The detection of such products at customs is not always simple, due to misleading packaging and the existence of products containing only legal components. Therefore there is a need for easy to use equipment and techniques to perform an initial screening of samples. The use of attenuated total reflectance-infrared (ATR-IR) spectroscopy, combined with chemometrics, was evaluated for that purpose. It was found that the combination of ATR-IR with the simple chemometric technique k-nearest neighbours gave good results. A model was obtained in which a minimum of illegal samples was categorised as legal. The correctly classified illegal samples could be attributed to the illegal components present.

    As illegal e-waste trade has been significantly growing over the course of the last few years, the consequences on human health and the environment demand immediate action on the part of the global community. Though it is argued that e-waste flows from developed to developing countries, this subject seems to be more complex than that, with a variety of studies suggesting that income per capita is not the only factor affecting the choice of regions that e-waste is illegally shipped to. How is a country's economic and social development associated with illegal e-waste trade? Is legislation an important factor? This paper aims at quantifying macroeconomic (per capita income and openness of economy) and social (human development and social progress) aspects, based on qualitative data on illegal e-waste trade routes, by examining the percentage differences in scorings in selected indicators for all known and suspected routes. The results show that illegal e-waste trade occurs from economically and socially developed regions to countries with significantly lower levels of overall development, with few exceptions, which could be attributed to the fact that several countries have loose regulations on e-waste trade, thus deeming them attractive for potential illegal activities.

    Full Text Available Illegal fishing net use is one of the most serious threats to the health of the world’s fisheries and for the secure employment of fishers. Illegal modes of fishing adversely affect the fishing industry according to the Fisheries and Aquatic Resource Ministry of Sri Lanka which is the regulatory body of the fisheries industry. In Sri Lanka, usage of illegal fishing methods has increased in recent years. There is an urgent need to identify prohibited or illegal fishing activities and the use of dangerous or harmful substances in fishing. The present study was carried out in the Mannar coastal area from June 2013 until the latter part of June 2014, to identify illegal, prohibited and dangerous fishing activities, and to understand the major threats and impacts on the fishing community and the socio, economic, biological and ecological impacts through field surveys and library methods. The study aims to outline appropriate planning and solutions to minimize illegal fishing and to save the coastal biodiversity and fishing community.

    "Counterfeit Drugs Kill" is the slogan the World Health Organization (WHO) uses in its anti-counterfeiting campaign. International organizations, governments of developed and developing countries, and the pharmaceutical industry created the IMPACT initiative (International Medical Products Anti-Counterfeiting Taskforce) to take on the thriving illegal industry that makes profits by selling fake drugs. However, before committing resources, policy makers want to assess the burden caused by counterfeit drugs in comparison with other health problems that compete for the limited resources available.

    The "Darknet" ("dark web") has emerged as a means by which illegal drug buys and deliveries can be arranged with apparent anonymity and impunity. Healthcare providers should be aware of this growing source of illicit drugs. The "Darknet" refers to networks isolated from the Internet that cannot be accessed via conventional search engines. They require special software that is protected by special encryption. The initial legitimate use of a "Darknet" to conceal personal information against misuse or political reprisal is being exploited to conceal the identity of buyers and sellers in illegal drug transactions. Instructions on how to obtain access to the "Darknet" are readily available on conventional Internet web pages. The "Darknet" has changed the paradigm of illegal drug importation and distribution by providing a difficult-to-trace transaction, and delivery via legitimate couriers directly to the home. © 2017 John Wiley & Sons Ltd.

    Illegal drug use continues to be a major threat to community health and safety. We used international drug surveillance databases to assess the relationship between multiple long-term estimates of illegal drug price and purity. We systematically searched for longitudinal measures of illegal drug supply indicators to assess the long-term impact of enforcement-based supply reduction interventions. Data from identified illegal drug surveillance systems were analysed using an a priori defined protocol in which we sought to present annual estimates beginning in 1990. Data were then subjected to trend analyses. Data were obtained from government surveillance systems assessing price, purity and/or seizure quantities of illegal drugs; systems with at least 10 years of longitudinal data assessing price, purity/potency or seizures were included. We identified seven regional/international metasurveillance systems with longitudinal measures of price or purity/potency that met eligibility criteria. In the USA, the average inflation-adjusted and purity-adjusted prices of heroin, cocaine and cannabis decreased by 81%, 80% and 86%, respectively, between 1990 and 2007, whereas average purity increased by 60%, 11% and 161%, respectively. Similar trends were observed in Europe, where during the same period the average inflation-adjusted price of opiates and cocaine decreased by 74% and 51%, respectively. In Australia, the average inflation-adjusted price of cocaine decreased 14%, while the inflation-adjusted price of heroin and cannabis both decreased 49% between 2000 and 2010. During this time, seizures of these drugs in major production regions and major domestic markets generally increased. With few exceptions and despite increasing investments in enforcement-based supply reduction efforts aimed at disrupting global drug supply, illegal drug prices have generally decreased while drug purity has generally increased since 1990. These findings suggest that expanding efforts at

    This paper addresses the problem of synthesizing plausible bipedal locomotion according to 3D anatomical reconstruction and general hypotheses on human motion control strategies. In a previous paper [Nicolas, G., Multon, F., Berillon, G., Marchal, F., 2007. From bone to plausible bipedal locomotion using inverse kinematics. Journal of Biomechanics 40 (5) 1048-1057], we have validated a method based on using inverse kinematics to obtain plausible lower-limb motions knowing the trajectory of the ankle. In this paper, we propose a more general approach that also involves computing a plausible trajectory of the ankles for a given skeleton. The inputs are the anatomical descriptions of the bipedal species, imposed footprints and a rest posture. This process is based on optimizing a reference ankle trajectory until a set of criteria is minimized. This optimization loop is based on the assumption that a plausible motion is supposed to have little internal mechanical work and should be as less jerky as possible. For each tested ankle trajectory, inverse kinematics is used to compute a lower-body motion that enables us to compute the resulting mechanical work and jerk. This method was tested on a set of modern humans (male and female, with various anthropometric properties). We show that the results obtained with this method are close to experimental data for most of the subjects. We also demonstrate that the method is not sensitive to the choice of the reference ankle trajectory; any ankle trajectory leads to very similar result. We finally apply the method to a skeleton of Pan paniscus (Bonobo), and compare the resulting motion to those described by zoologists.

    "For export only" anti-inflammatory and lightening creams are medicinal products sold in African countries for their skin whitening action. In the last years, Rapid Alerts from European Medicinal Regulatory Agencies evidenced the presence of a large number of illegal and counterfeit anti-inflammatory products advertised for their whitening action on black skin in the European market. These drugs, containing glucocorticoids, are illegally sold in Europe in unauthorized ethno-cosmetics-shops and mainly bought by immigrants. This paper reports a new RP-LC method for the rapid simultaneous screening of six different active ingredients in anti-inflammatory and whitening products (creams, ointment and suspension): betamethasone dipropionate, dexamethasone, fluocinonide, fluocinolone acetonide, clobetasol propionate, methyl-prednisolone acetate. The method was developed and validated in view of its possible application in quality control laboratories, mainly those appointed to the control of illegal/counterfeit medicinal products. The associated measurement uncertainty was calculated from validation data. The method was then applied to the analysis of whitening products obtained from the Italian illegal market.

Herein, we introduce an automated web crawling surveillance system developed to monitor reports on illegally traded wildlife. A resource for enforcement officials as well as the general public, the freely available website, http://www.healthmap.org/wildlifetrade, provides a customizable visualization of worldwide reports on interceptions of illegally traded wildlife and wildlife products. From August 1, 2010 to July 31, 2011, publicly available English language illegal wildlife trade reports from official and unofficial sources were collected and categorized by location and species involved. During this interval, 858 illegal wildlife trade reports were collected from 89 countries.

    Illegal imports of meat can present substantial risks to public and animal health. Several European countries have reported considerable quantities of meat imported on commercial passenger flights. The objective of this study was to estimate the quantity of meat illegally imported into Switzerland, with a separate estimation for bushmeat. Data were obtained by participation in intervention exercises at Swiss international airports and by analysing data on seizures during the four-year period 2008 to 2011. The study revealed that a wide array of animal species was imported into Switzerland. From the database, the average annual weight of meat seized during the period analysed was 5.5 tonnes, of which 1.4% was bushmeat. However, in a stochastic model the total annual inflow of illegal meat imports was estimated at 1,013 tonnes (95% CI 226 to 4,192) for meat and 8.6 tonnes (95% CI 0.8 to 68.8) for bushmeat. Thus, even for a small European country such as Switzerland the quantities of illegally imported meat and meat products are substantial and the consequences for public and animal health could be high. To reduce the risk, it is essential that surveillance at European airports is harmonised and that passenger information campaigns clarify the consequences of the illegal import of meat, particularly bushmeat.

    2013-11-01

    Full Text Available Current judging of race walking in international competitions relies on subjective human observation to detect illegal gait, which naturally has inherent problems. Incorrect judging decisions may devastate an athlete and possibly discredit the international governing body. The aim of this study was to determine whether an inertial sensor could improve accuracy, monitor every step the athlete makes in training and/or competition. Seven nationally competitive race walkers performed a series of legal, illegal and self-selected pace races. During testing, athletes wore a single inertial sensor (100 Hz placed at S1 of the vertebra and were simultaneously filmed using a high-speed camera (125 Hz. Of the 80 steps analyzed the high-speed camera identified 57 as illegal, the inertial sensor misidentified four of these measures (all four missed illegal steps had 0.008 s of loss of ground contact which is considerably less than the best possible human observation of 0.06 s. Inertial sensor comparison to the camera found the typical error of estimate was 0.02 s (95% confidence limits 0.01–0.02, with a bias of 0.02 (±0.01. An inertial sensor can thus objectively improve the accuracy in detecting illegal steps (loss of ground contact and, along with the ability to monitor every step of the athlete, could be a valuable tool to assist judges during race walk events.

    The purposes of this study were to examine the specific contribution of illegal acts to the diagnostic criteria of pathological gambling, to assess the possibility of differential item functioning across patients' sex and age, and to explore the existence of different clinical phenotypes based on the presence of illegal acts. The sample consisted of 2,155 patients seeking treatment for pathological gambling at the University Hospital of Bellvitge in Barcelona, Spain. The illegal acts item did not show different item functioning, and younger patients presented higher latent means than middle-aged and older patients, whereas no differences were found across sex. This item also showed the lowest discrimination coefficient; its exclusion would maintain satisfactory internal consistency for the remaining 9 symptoms and was poorly related to psychopathology and the severity of the gambling behavior. The relevance of the illegal acts as a diagnostic criterion appears to be limited, and its elimination from the Diagnostic and Statistical Manual for Mental Disorders, 5th edition, seems justified. However, illegal acts have implications for both the clinical and legal domains and contribute to increase the patients' impairment.

    Illegal dumping of solid waste not only affecting the environment but also social life of communities, hence authorities should have an effective system to cater this problem. Malaysia is experiencing extensive physical developments and this has led to an increase of construction waste illegal dumping. However, due to the lack of proper data collection, the actual figure for construction waste illegal dumping in Malaysia are not available. This paper presents a mapping of construction waste illegal dumping in Kluang district, Johor using Geographic Information System (GIS) software. Information of the dumped waste such as coordinate, photos, types of material and quantity of waste were gathered manually through site observation for three months period. For quantifying the dumped waste, two methods were used which are the first method is based on shape of the waste (pyramids or squares) while the second method is based weighing approach. All information regarding the waste was assigned to the GIS for the mapping process. Results indicated a total of 12 types of construction waste which are concrete, tiles, wood, gypsum board, mixed construction waste, brick and concrete, bricks, sand, iron, glass, pavement and tiles, and concrete at 64 points locations of illegal dumping on construction waste in Kluang. These wastes were accounted to an estimated volume of 427.2636 m3. Hopefully, this established map will assist Kluang authority to improve their solid waste management system in Kluang.

  16. Tracking illegal small arms traffic across U.S. borders through the implementation of firearm microstamping to small arms and small arms exports

    At a border security conference in August 2008, Michael Sullivan, acting director of Bureau of Alcohol, Tobacco, Firearms and Explosives stated that, "Nearly all illegal firearms (90% to 95%) seized in Mexico come from the United States"[1]. When firearms are recovered at a crime scene, the firearms can be traced providing specific details on illegal firearm dealers or straw purchasers within the United States. Criminals or narco terrorist groups target US dealers to source firearms for drug cartels in Mexico and South America. Joint law enforcement programs between the US and Mexico law enforcement have been effective, however, in most cases the firearms that are seized are only a small fraction of the firearms trafficked across the United States border. A technology called Microstamping, when applied to newly manufactured firearms will provide further opportunities for tracing illegal firearms for law enforcement in the United States and across the globe. Microstamping is a patented technology and trace solution where intentional tooling marks are formed or micromachined onto firearms interior surfaces that come into contact or impact the surfaces of cartridge casings. The intentional tooling marks can take the form of alphanumeric codes or encoded geometric codes, such as a barcode. As the firearm is discharged the intentional tooling marks transfer a code to the cartridge casing before it is ejected out of the firearm. When recovered at the scene of an incident, the Microstamped cartridge can indentify a specific firearm, without the need to recover that firearm. Microstamping provides critical intelligence for use in border security operations and cross border violent drug related crime investigations. This paper will explain the key attributes of microstamping technology; including its potential benefits in border security operations and how data gathered from the technique can be used in geospatial information systems to identify illicit firearm sources

  17. Biologically plausible learning in recurrent neural networks reproduces neural dynamics observed during cognitive tasks.

    2017-02-23

    Neural activity during cognitive tasks exhibits complex dynamics that flexibly encode task-relevant variables. Chaotic recurrent networks, which spontaneously generate rich dynamics, have been proposed as a model of cortical computation during cognitive tasks. However, existing methods for training these networks are either biologically implausible, and/or require a continuous, real-time error signal to guide learning. Here we show that a biologically plausible learning rule can train such recurrent networks, guided solely by delayed, phasic rewards at the end of each trial. Networks endowed with this learning rule can successfully learn nontrivial tasks requiring flexible (context-dependent) associations, memory maintenance, nonlinear mixed selectivities, and coordination among multiple outputs. The resulting networks replicate complex dynamics previously observed in animal cortex, such as dynamic encoding of task features and selective integration of sensory inputs. We conclude that recurrent neural networks offer a plausible model of cortical dynamics during both learning and performance of flexible behavior.

    When planning resequencing studies for complex diseases, previous association and linkage studies can constrain the range of plausible genetic models for a given locus. Here, we explore the combinations of causal risk allele frequency (RAFC ) and genotype relative risk (GRRC ) consistent with no or limited evidence for affected sibling pair (ASP) linkage and strong evidence for case-control association. We find that significant evidence for case-control association combined with no or moderate evidence for ASP linkage can define a lower bound for the plausible RAFC . Using data from large type 2 diabetes (T2D) linkage and genome-wide association study meta-analyses, we find that under reasonable model assumptions, 23 of 36 autosomal T2D risk loci are unlikely to be due to causal variants with combined RAFC < 0.005, and four of the 23 are unlikely to be due to causal variants with combined RAFC < 0.05.

    The massive accumulation of biomedical knowledge is reflected by the growth of the literature database MEDLINE with over 23 million bibliographic records. All records are manually indexed by MeSH descriptors, many of them refined by MeSH subheadings. We use subheading information to cluster types of MeSH descriptor co-occurrences in MEDLINE by processing co-occurrence information provided by the UMLS. The goal is to infer plausible predicates to each resulting cluster. In an initial experiment this was done by grouping disease-pharmacologic substance co-occurrences into six clusters. Then, a domain expert manually performed the assignment of meaningful predicates to the clusters. The mean accuracy of the best ten generated biomedical facts of each cluster was 85%. This result supports the evidence of the potential of MeSH subheadings for extracting plausible medical predications from MEDLINE.

    A written single word spelling to dictation test and a single word reading test were given to 68 severe-profoundly oral deaf 10-11-year-old children and 20 hearing children with a diagnosis of dyslexia. The literacy scores of the deaf children and the hearing children with dyslexia were lower than expected for children of their age and did not differ from each other. Three quarters of the spelling errors of hearing children with dyslexia compared with just over half the errors of the oral deaf group were phonologically plausible. Expressive vocabulary and speech intelligibility predicted the percentage of phonologically plausible errors in the deaf group only. Implications of findings for the phonological decoding self-teaching model and for supporting literacy development are discussed.

  1. Of paradox and plausibility: the dynamic of change in medical law.

    Science.gov (United States)

    Harrington, John

    2014-01-01

    This article develops a model of change in medical law. Drawing on systems theory, it argues that medical law participates in a dynamic of 'deparadoxification' and 'reparadoxification' whereby the underlying contingency of the law is variously concealed through plausible argumentation, or revealed by critical challenge. Medical law is, thus, thoroughly rhetorical. An examination of the development of the law on abortion and on the sterilization of incompetent adults shows that plausibility is achieved through the deployment of substantive common sense and formal stylistic devices. It is undermined where these elements are shown to be arbitrary and constructed. In conclusion, it is argued that the politics of medical law are constituted by this antagonistic process of establishing and challenging provisionally stable normative regimes.

    The increase in solar ultraviolet radiation can have various direct and indirect effects on human health, like the incidence of ocular damage. Data of eye damage in residents of three suburban regions in Greece and in two groups of monks/nuns and fishermen are examined here. The statistics performed on these data provides new information about the plausible association between increased levels of solar ultraviolet radiation, air-pollution at ground level, and the development of ocular defects.

  3. Families of Plausible Solutions to the Puzzle of Boyajian’s Star

    2016-09-01

    Good explanations for the unusual light curve of Boyajian's Star have been hard to find. Recent results by Montet & Simon lend strength and plausibility to the conclusion of Schaefer that in addition to short-term dimmings, the star also experiences large, secular decreases in brightness on decadal timescales. This, combined with a lack of long-wavelength excess in the star's spectral energy distribution, strongly constrains scenarios involving circumstellar material, including hypotheses invoking a spherical cloud of artifacts. We show that the timings of the deepest dimmings appear consistent with being randomly distributed, and that the star's reddening and narrow sodium absorption is consistent with the total, long-term dimming observed. Following Montet & Simon's encouragement to generate alternative hypotheses, we attempt to circumscribe the space of possible explanations with a range of plausibilities, including: a cloud in the outer solar system, structure in the interstellar medium (ISM), natural and artificial material orbiting Boyajian's Star, an intervening object with a large disk, and variations in Boyajian's Star itself. We find the ISM and intervening disk models more plausible than the other natural models.

    2013-10-01

    Three experiments investigated how font emphasis influences reading and remembering discourse. Although past work suggests that contrastive pitch contours benefit memory by promoting encoding of salient alternatives, it is unclear both whether this effect generalizes to other forms of linguistic prominence and how the set of alternatives is constrained. Participants read discourses in which some true propositions had salient alternatives (e.g., British scientists found the endangered monkey when the discourse also mentioned French scientists) and completed a recognition memory test. In Experiments 1 and 2, font emphasis in the initial presentation increased participants' ability to later reject false statements about salient alternatives but not about unmentioned items (e.g., Portuguese scientists). In Experiment 3, font emphasis helped reject false statements about plausible alternatives, but not about less plausible alternatives that were nevertheless established in the discourse. These results suggest readers encode a narrow set of only those alternatives plausible in the particular discourse. They also indicate that multiple manipulations of linguistic prominence, not just prosody, can lead to consideration of alternatives.

  5. A biologically plausible model of time-scale invariant interval timing.

    The temporal durations between events often exert a strong influence over behavior. The details of this influence have been extensively characterized in behavioral experiments in different animal species. A remarkable feature of the data collected in these experiments is that they are often time-scale invariant. This means that response measurements obtained under intervals of different durations coincide when plotted as functions of relative time. Here we describe a biologically plausible model of an interval timing device and show that it is consistent with time-scale invariant behavior over a substantial range of interval durations. The model consists of a set of bistable units that switch from one state to the other at random times. We first use an abstract formulation of the model to derive exact expressions for some key quantities and to demonstrate time-scale invariance for any range of interval durations. We then show how the model could be implemented in the nervous system through a generic and biologically plausible mechanism. In particular, we show that any system that can display noise-driven transitions from one stable state to another can be used to implement the timing device. Our work demonstrates that a biologically plausible model can qualitatively account for a large body of data and thus provides a link between the biology and behavior of interval timing.

  6. Illegal logging in the Northern Sierra Madre Natural Park, the Philippines

    2011-01-01

    Full Text Available Illegal logging is a threat to biodiversity and rural livelihoods in the Northern Sierra Madre Natural Park, the largest protected area in the Philippines. Every year between 20,000 and 35,000 cu. m wood is extracted from the park. The forestry service and municipal governments tolerate illegal logging in the protected area; government officials argue that banning an important livelihood activity of households along the forest frontier will aggravate rural poverty. However this reasoning underestimates the scale of timber extraction, and masks resource capture and collusive corruption. Illegal logging in fact forms an obstacle for sustainable rural development in and around the protected area by destroying ecosystems, distorting markets, and subverting the rule of law. Strengthening law enforcement and controlling corruption are prerequisites for sustainable forest management in and around protected areas in insular southeast Asia.

    "Based on micro data from the Immigration and Naturalization Service (INS) on legal immigrants as well as on legalization applications that followed the passage of IRCA [the Immigration Reform and Control Act of 1986], this study exploits the variation in legal and illegal immigration flows across seventy source countries to examine the sensitivity of immigration flows to underlying source country characteristics. The study finds that earnings in the source country and the distance from the United States form significant deterrents of both legal and illegal immigration flows. We also find that illegal immigration is more sensitive to such factors than is legal immigration." The impact of the North American Free Trade Agreement on U.S. immigration from Mexico is also assessed.

This article examines the Immigration Services Branch of the South African Department of Home Affairs, a state bureaucracy widely deemed “illegible......Recent anthropological accounts of the state have demonstrated the potential for danger or illegibility in the public's encounter with the state. Much of this work has taken the perspective of the public, however, and less has been said about how functionaries of the state perceive...... to stabilize these two unstable entities, but they also enable officials to act in ways that might run counter to official discourse while simultaneously upholding its legitimacy. Their stabilization efforts therefore incite a destabilization of the state, leading it to appear as “magical” or “illegible...

    In a multicenter, prospective, randomized, open-label study of isoniazid-preventive therapy (IPT) for latent tuberculosis infection, illegal immigrants from countries where tuberculosis is highly endemic were enrolled at two clinical sites in Northern Italy. Of 208 eligible subjects, 82 received supervised IPT at a dose of 900 mg twice weekly for 6 mo (Regimen A), 73 received unsupervised IPT 900 mg twice weekly for 6 mo (Regimen B), and 53 received unsupervised IPT 300 mg daily for 6 mo (Regimen C). Supervised IPT was delivered at either one tuberculosis clinic or one migrant clinic. The probability of completing a 26-wk regimen was 7, 26, and 41% in Regimens A, B, and C, respectively (p illegal immigrants was low. Supervised, clinic-based administration of IPT significantly reduced adherence. Alternative strategies to implement preventive therapy in illegal immigrants are clearly required.

    2013-01-01

    Reliable evidence of trends in the illegal ivory trade is important for informing decision making for elephants but it is difficult to obtain due to the covert nature of the trade. The Elephant Trade Information System, a global database of reported seizures of illegal ivory, holds the only extensive information on illicit trade available. However inherent biases in seizure data make it difficult to infer trends; countries differ in their ability to make and report seizures and these differences cannot be directly measured. We developed a new modelling framework to provide quantitative evidence on trends in the illegal ivory trade from seizures data. The framework used Bayesian hierarchical latent variable models to reduce bias in seizures data by identifying proxy variables that describe the variability in seizure and reporting rates between countries and over time. Models produced bias-adjusted smoothed estimates of relative trends in illegal ivory activity for raw and worked ivory in three weight classes. Activity is represented by two indicators describing the number of illegal ivory transactions--Transactions Index--and the total weight of illegal ivory transactions--Weights Index--at global, regional or national levels. Globally, activity was found to be rapidly increasing and at its highest level for 16 years, more than doubling from 2007 to 2011 and tripling from 1998 to 2011. Over 70% of the Transactions Index is from shipments of worked ivory weighing less than 10 kg and the rapid increase since 2007 is mainly due to increased consumption in China. Over 70% of the Weights Index is from shipments of raw ivory weighing at least 100 kg mainly moving from Central and East Africa to Southeast and East Asia. The results tie together recent findings on trends in poaching rates, declining populations and consumption and provide detailed evidence to inform international decision making on elephants.

    To determine the patterns of substance abuse of students attending the Lugo School of Nursing. Observational, descriptive and cross-sectional study in the classroom carried out by survey research in April 2015. 61.5% of students participated (185), 83.2% of whom were females. The first addictive substance consumed by participants was tobacco (at 15 years old). In the last month cigarettes were consumed by 36.2% of students, while alcohol was consumed by 89.9% (58.4% of the total got drunk). 2.2% were consuming tranquilizers/hypnotics in the same time period. The most widely used illegal drug was cannabis (17.8%) and then cocaine (2.2%). There is a significant correlation between illegal drug consumption and being male, smoking cigarettes or drinking alcohol, living alone or with friends (not family), have poor academic performance and public drinking (botellón). There were no association between illegal drugs and sports or reading. Polydrug use was also studied: a 16.2% declared to have consumed alcohol and cannabis simultaneously, and a 4.9% alcohol and cocaine. Consumption patterns are similar compared to the general population in that age group, with some of them being higher. Therefore, it is necessary to take measures in order to prevent substance abuse at the university level. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

    2015-10-01

    Full Text Available Illegal disposal of waste is a significant management issue for contemporary governments with waste posing an economic, social, and environmental risk. An improved understanding of the distribution of illegal waste disposal sites is critical to enhance the cost-effectiveness and efficiency of waste management efforts. Remotely sensed data has the potential to address this knowledge gap. However, the literature regarding the use of remote sensing to map illegal waste disposal sites is incomplete. This paper aims to analyze existing remote sensing methods and sensors used to monitor and map illegal waste disposal sites. The purpose of this paper is to support the evaluation of existing remote sensing methods for mapping illegal domestic waste sites in Queensland, Australia. Recent advances in technology and the acquisition of very high-resolution remote sensing imagery provide an important opportunity to (1 revisit established analysis techniques for identifying illegal waste disposal sites, (2 examine the applicability of different remote sensors for illegal waste disposal detection, and (3 identify opportunities for future research to increase the accuracy of any illegal waste disposal mapping products.

  1. Understanding Karma Police: The Perceived Plausibility of Noun Compounds as Predicted by Distributional Models of Semantic Representation

    Science.gov (United States)

    Günther, Fritz; Marelli, Marco

    2016-01-01

    Noun compounds, consisting of two nouns (the head and the modifier) that are combined into a single concept, differ in terms of their plausibility: school bus is a more plausible compound than saddle olive. The present study investigates which factors influence the plausibility of attested and novel noun compounds. Distributional Semantic Models (DSMs) are used to obtain formal (vector) representations of word meanings, and compositional methods in DSMs are employed to obtain such representations for noun compounds. From these representations, different plausibility measures are computed. Three of those measures contribute in predicting the plausibility of noun compounds: The relatedness between the meaning of the head noun and the compound (Head Proximity), the relatedness between the meaning of modifier noun and the compound (Modifier Proximity), and the similarity between the head noun and the modifier noun (Constituent Similarity). We find non-linear interactions between Head Proximity and Modifier Proximity, as well as between Modifier Proximity and Constituent Similarity. Furthermore, Constituent Similarity interacts non-linearly with the familiarity with the compound. These results suggest that a compound is perceived as more plausible if it can be categorized as an instance of the category denoted by the head noun, if the contribution of the modifier to the compound meaning is clear but not redundant, and if the constituents are sufficiently similar in cases where this contribution is not clear. Furthermore, compounds are perceived to be more plausible if they are more familiar, but mostly for cases where the relation between the constituents is less clear. PMID:27732599

  5. China's Rare Earth Supply Chain: Illegal Production, and Response to new Cerium Demand

    Nguyen, Ruby Thuy; Imholte, D. Devin

    2016-07-01

    As the demand for personal electronic devices, wind turbines, and electric vehicles increases, the world becomes more dependent on rare earth elements. Given the volatile, Chinese-concentrated supply chain, global attempts have been made to diversify supply of these materials. However, the overall effect of supply diversification on the entire supply chain, including increasing low-value rare earth demand, is not fully understood. This paper is the first attempt to shed some light on China's supply chain from both demand and supply perspectives, taking into account different Chinese policies such as mining quotas, separation quotas, export quotas, and resource taxes. We constructed a simulation model using Powersim Studio that analyzes production (both legal and illegal), production costs, Chinese and rest-of-world demand, and market dynamics. We also simulated new demand of an automotive aluminum-cerium alloy in the US market starting from 2018. Results showed that market share of the illegal sector has grown since 2007-2015, ranging between 22% and 25% of China's rare earth supply, translating into 59-65% illegal heavy rare earths and 14-16% illegal light rare earths. There will be a shortage in certain light and heavy rare earths given three production quota scenarios and constant demand growth rate from 2015 to 2030. The new simulated Ce demand would require supply beyond that produced in China. Finally, we illustrate revenue streams for different ore compositions in China in 2015.

    Urban waste impacts human and environmental health, and waste management has become one of the major challenges of humanity. Concurrently with new directives due to manage this human by-product, illegal dumping has become one of the most lucrative activities of organized crime. Beyond economic fraud, illegal waste disposal strongly enhances uncontrolled dissemination of human pathogens, pollutants and invasive species. Here, we demonstrate the potential of novel real-time GPS tracking of scavenging species to detect environmental crime. Specifically, we were able to detect illegal activities at an officially closed dump, which was visited recurrently by 5 of 19 GPS-tracked yellow-legged gulls (Larus michahellis). In comparison with conventional land-based surveys, GPS tracking allows a much wider and cost-efficient spatiotemporal coverage, even of the most hazardous sites, while GPS data accessibility through the internet enables rapid intervention. Our results suggest that multi-species guilds of feathered detectives equipped with GPS and cameras could help fight illegal dumping at continental scales. We encourage further experimental studies, to infer waste detection thresholds in gulls and other scavenging species exploiting human waste dumps.

Our results suggest that multi-species guilds of feathered detectives equipped with GPS and cameras could help fight illegal dumping at continental scales. We encourage further experimental studies, to infer waste detection thresholds in gulls and other scavenging species exploiting human waste dumps.

    Urban waste impacts human and environmental health, and waste management has become one of the major challenges of humanity. Concurrently with new directives due to manage this human by-product, illegal dumping has become one of the most lucrative activities of organized crime. Beyond economic fraud, illegal waste disposal strongly enhances uncontrolled dissemination of human pathogens, pollutants and invasive species. Here, we demonstrate the potential of novel real-time GPS tracking of scavenging species to detect environmental crime. Specifically, we were able to detect illegal activities at an officially closed dump, which was visited recurrently by 5 of 19 GPS-tracked yellow-legged gulls (Larus michahellis). In comparison with conventional land-based surveys, GPS tracking allows a much wider and cost-efficient spatiotemporal coverage, even of the most hazardous sites, while GPS data accessibility through the internet enables rapid intervention. Our results suggest that multi-species guilds of feathered detectives equipped with GPS and cameras could help fight illegal dumping at continental scales.

    Full Text Available A novel growth process of silver nanowires was revealed by tracing the morphology evolution of Ag nanostructures fabricated by an improved polyol process. A mixture of Ag nanowires and nanoparticles was obtained with the usage of PVP-K25 (MW = 38,000. The products sampled at different reaction time were studied in detail using UV-visible absorption spectra and transmission electron microscopy (TEM. An interesting phenomenon unknown in the past was observed where Ag nanoparticles undergo an important dissolution-recrystallization process and Ag nanowires are formed at the expense of the preformed Ag nanoparticles. A plausible novel growth mechanism for the silver nanowires was proposed.

Truth-finding capacity therefore does belong in legitimacy debates as a challenge that can plausibly be raised against them.

    This study introduces a new Generalized Leaky Integrate-and-Fire (GLIF) neuron model. Unlike Normal Leaky Integrate-and-Fire (NLIF) models, the leaking resistor in the GLIF model equation is assumed to be variable, and an additional term would have the bias current added to the model equation in order to improve the accuracy. Adjusting the parameters defined for the leaking resistor and bias current, a GLIF model could be accurately matched to any Hodgkin-Huxley (HH) model and be able to reproduce plausible biological neuron behaviors.

    Long-term phenological observations are now recognized as important indicators for climate change impact studies. With the increased need for phenological data, there is also an increased need for higher data quality. Since 1951 MeteoSwiss has been operating a national phenological observation network. Currently the network consists of about 150 active stations observing up to 69 different phenophases. An important aim of a running three years project at MeteoSwiss is a further increase of the quality of the collected data. The higher data quality will be achieved by an automated procedure performing plausibility checks on the data and by online data-entry. Further measures such as intensified observer instructions and collection of more detailed metadata also contribute to a high data quality standard. The plausibility checks include the natural order of the phenophases within a species and also between different species (with regard to possible natural deviation). Additionally it will be checked if the observed date differs by less than two standard deviations from the average for this phenophase at the altitude of the station. A value outside of these limits is not necessarily a false value, since occurrences of extreme values will be beyond these limits. Therefore, within this check of the limits, the timing of the season of the respective year will also be taken into account. In case of an implausible value a comparison with other stations of the same region and sea level is proposed. A further possibility of data quality control could be to model the different phenophases statistically and to use this model for estimating the likelihood of observed values. An overall exploratory data analysis is currently performed providing a solid basis to implement the best possible methods for the plausibility checks. Important advantages of online data-entry are the near real-time availability of the data as well as the avoidance of various kinds of typical mistakes

    Empirical models are frequently applied to produce landslide susceptibility maps for large areas. Subsequent quantitative validation results are routinely used as the primary criteria to infer the validity and applicability of the final maps or to select one of several models. This study hypothesizes that such direct deductions can be misleading. The main objective was to explore discrepancies between the predictive performance of a landslide susceptibility model and the geomorphic plausibility of subsequent landslide susceptibility maps while a particular emphasis was placed on the influence of incomplete landslide inventories on modelling and validation results. The study was conducted within the Flysch Zone of Lower Austria (1,354 km2) which is known to be highly susceptible to landslides of the slide-type movement. Sixteen susceptibility models were generated by applying two statistical classifiers (logistic regression and generalized additive model) and two machine learning techniques (random forest and support vector machine) separately for two landslide inventories of differing completeness and two predictor sets. The results were validated quantitatively by estimating the area under the receiver operating characteristic curve (AUROC) with single holdout and spatial cross-validation technique. The heuristic evaluation of the geomorphic plausibility of the final results was supported by findings of an exploratory data analysis, an estimation of odds ratios and an evaluation of the spatial structure of the final maps. The results showed that maps generated by different inventories, classifiers and predictors appeared differently while holdout validation revealed similar high predictive performances. Spatial cross-validation proved useful to expose spatially varying inconsistencies of the modelling results while additionally providing evidence for slightly overfitted machine learning-based models. However, the highest predictive performances were obtained for

    Full Text Available Visual object recognition occurs easily despite differences in position, size, and rotation of the object, but the neural mechanisms responsible for this invariance are not known. We have found a set of transforms that achieve invariance in a neurally plausible way. We find that a transform based on local spatial frequency analysis of oriented segments and on logarithmic mapping, when applied twice in an iterative fashion, produces an output image that is unique to the object and that remains constant as the input image is shifted, scaled or rotated.

This study determined the area of the Offin shelterbelt forest reserve, Ghana, degraded through illegal mining (galamsey and the impacts on the livelihoods of fringe communities. Thirty-two (32 coordinates were recorded around the peripheries of disturbed site in the reserve using hand-held Global Positioning System and were then imported into a geodatabase in ArcGIS which was used to estimate the area degraded. Data was obtained from 60 purposively sampled respondents from two communities fringing the reserve and 10 key informant interviews. Increased income (13%, employment opportunities (6.7% and increased market activities (2% were some benefits of the illegal mining activities identified by the respondents. Eight respondents associated their employment with of the advent of illegal mining activities out which 6 (70% were engaged directly in mining activities, while 2 (30% were into trading. The miners earned cash income range of US $ 2.9–22.9 daily.

    The appearance of dangerous and insufficiently studied designer drugs has increased substantially within the last few years. Mixtures containing centrally active compounds are often declared as "bath salt", "incense", "plant food", "bong cleaners" and are marketed in head shops and on the Internet. As the majority of the ingredients of such products are not subject to regulations of the German Narcotics Law (Betäubungsmittelgesetz, BtMG), the vendors and consumers mistake the sale of such products for legal. An alternative possibility to prosecute the distribution of so-called "legal highs" arises from the regulations of the German Medicinal Products Act (Arzneimittelgesetz, AMG). Indicating a private address, several products were purchased via the Internet. The products were analyzed by gas chromatography- mass spectrometry using computer-assisted database search and potential hits were checked for plausibility. The analysis of 100 samples revealed centrally acting compounds (including caffeine) in 98 % (75 % of all samples positive for caffeine). In 16 % of the samples, drugs subject to the BtMG at the time of purchase (end of 2011) were found including 2,5-dimethoxy-4-methylamphetamine, amphetamine, etilamphetamine, N-benzylpiperazine, mephedrone, methcathinone, and phenobarbital. In 55 % of the samples, drugs subject to the current BtMG were found (after its amendment on 20 July 2012). In 37 % of the samples, substances subject to the AMG were found (e.g. ephedrine). In 35 % of the samples, drugs with a potential psychotropic effect were found. In 57.3 % of the positive samples, more than one active ingredient was determined and in some cases up to five active components were found. Other interesting pharmacologically active ingredients found were 4-methylcathinone (n=13), flephedrone (n=8), trifluoromethylphenyl-piperazine (n=7), methylone (n=5), butylone (n=2), hordenine (n=2), and harmane (n=2).

    2016-07-21

    This article addresses illegal drug use within the current debate in traditional public health and in proposals from Latin America, while emphasizing the need to approach the issue from an alternative public health perspective centered on individual users, groups, and social movements as protagonists. This counterhegemonic approach thus aims to orient the discussion on the need for inclusive and democratic public policies. Illegal drug use has been addressed from various perspectives: clinical medicine, viewing it as a problem that generates mental disorders and infectious diseases, both through risky sexual practices and/or use of injecting paraphernalia; from a legal perspective, as a problem related to delinquency; and according to traditional public health, as a problem that generates school dropout and work absenteeism and increases the demand on health services, in addition to increasing violence and death. However, not all forms of drug consumption involve problematic use, nor do they all trigger disorders related to substance use.

  10. A Biomass-based Model to Estimate the Plausibility of Exoplanet Biosignature Gases

    Seager, S; Hu, R

    2013-01-01

    Biosignature gas detection is one of the ultimate future goals for exoplanet atmosphere studies. We have created a framework for linking biosignature gas detectability to biomass estimates, including atmospheric photochemistry and biological thermodynamics. The new framework is intended to liberate predictive atmosphere models from requiring fixed, Earth-like biosignature gas source fluxes. New biosignature gases can be considered with a check that the biomass estimate is physically plausible. We have validated the models on terrestrial production of NO, H2S, CH4, CH3Cl, and DMS. We have applied the models to propose NH3 as a biosignature gas on a "cold Haber World," a planet with a N2-H2 atmosphere, and to demonstrate why gases such as CH3Cl must have too large of a biomass to be a plausible biosignature gas on planets with Earth or early-Earth-like atmospheres orbiting a Sun-like star. To construct the biomass models, we developed a functional classification of biosignature gases, and found that gases (such...

    The spontaneous formation of closed bilayer structures from prebiotically plausible amphiphiles is an essential requirement for the emergence of early cells on prebiotic Earth. The sources of amphiphiles could have been both endo- and exogenous (accretion of meteorite carbonaceous material or interstellar dust particles). Among all prebiotic possible amphiphile candidates, those containing phosphate are the least investigated species because their self-assembly occurs in a seemingly too narrow range of conditions. The self-assembly of simple phosphate amphiphiles should, however, be of great interest, as contemporary membranes predominantly contain phospholipids. In contrast to common expectations, we show that these amphiphiles can be easily synthesized under prebiotically plausible environmental conditions and can efficiently form bilayer structures in the presence of various co-surfactants across a large range of pH values. Vesiculation was even observed in crude reaction mixtures that contained 1-decanol as the amphiphile precursor. The two best co-surfactants promoted vesicle formation over the entire pH range in aqueous solutions. Expanding the pH range where bilayer membranes self-assemble and remain intact is a prerequisite for the emergence of early cell-like compartments and their preservation under fluctuating environmental conditions. These mixed bilayers also retained small charged solutes, such as dyes. These results demonstrate that alkyl phosphate amphiphiles might have played a significant role as early compartment building blocks.

  12. A swarm intelligence framework for reconstructing gene networks: searching for biologically plausible architectures.

    Kentzoglanakis, Kyriakos; Poole, Matthew

    2012-01-01

    In this paper, we investigate the problem of reverse engineering the topology of gene regulatory networks from temporal gene expression data. We adopt a computational intelligence approach comprising swarm intelligence techniques, namely particle swarm optimization (PSO) and ant colony optimization (ACO). In addition, the recurrent neural network (RNN) formalism is employed for modeling the dynamical behavior of gene regulatory systems. More specifically, ACO is used for searching the discrete space of network architectures and PSO for searching the corresponding continuous space of RNN model parameters. We propose a novel solution construction process in the context of ACO for generating biologically plausible candidate architectures. The objective is to concentrate the search effort into areas of the structure space that contain architectures which are feasible in terms of their topological resemblance to real-world networks. The proposed framework is initially applied to the reconstruction of a small artificial network that has previously been studied in the context of gene network reverse engineering. Subsequently, we consider an artificial data set with added noise for reconstructing a subnetwork of the genetic interaction network of S. cerevisiae (yeast). Finally, the framework is applied to a real-world data set for reverse engineering the SOS response system of the bacterium Escherichia coli. Results demonstrate the relative advantage of utilizing problem-specific knowledge regarding biologically plausible structural properties of gene networks over conducting a problem-agnostic search in the vast space of network architectures.

    Reptile prime ministers and flying Nazi saucers-extreme and sometimes off-wall conclusion are typical ingredients of conspiracy theories. While individual differences are a common research topic concerning conspiracy theories, the role of extreme statements in the process of acquiring and passing on conspiratorial stories has not been regarded in an experimental design so far. We identified six morphological components of conspiracy theories empirically. On the basis of these content categories a set of narrative elements for a 9/11 story was compiled. These elements varied systematically in terms of conspiratorial allegation, i.e., they contained official statements concerning the events of 9/11, statements alleging to a conspiracy limited in time and space as well as extreme statements indicating an all-encompassing cover-up. Using the method of narrative construction, 30 people were given a set of cards with these statements and asked to construct the course of events of 9/11 they deem most plausible. When extreme statements were present in the set, the resulting stories were more conspiratorial; the number of official statements included in the narrative dropped significantly, whereas the self-assessment of the story's plausibility did not differ between conditions. This indicates that blatant statements in a pool of information foster the synthesis of conspiracy theories on an individual level. By relating these findings to one of Germany's most successful (and controversial) non-fiction books, we refer to the real-world dangers of this effect.

    2013-08-01

    In 2011 the Taiwan Food and Drug Administration reported that plasticizers di(2-ethylhexyl) phthalate (DEHP) and di-iso-nonyl phthalate (DiNP), endocrine disruptors, were illegally added to clouding agents used in foods and beverages. 965 products were found contaminated, of which 206 were exported to 22 countries. This study's purpose was to obtain English names for 28 contaminated products for which DEHP levels were reported, calculate estimated average daily intake (mg/kg/day) for a 50 kg woman consuming one portion, and compare to U.S. and E.U. guidelines for daily intake. We found that drinking just one bottle (500 ml) of sports drinks would result in an average DEHP intake of 0.14 mg/kg bw/day (range 0.091-0.341), which exceeds by several fold government guidelines (0.02-0.06 mg/kg bw/day). One (2 g) serving from 4/14 samples of contaminated dietary supplements exceeds the guideline of 0.02 mg/kg bw/day. In conclusion, consuming even one portion of tainted drinks and some powders would lead to daily intake of DEHP that greatly exceeds established safety guidelines, raising concerns about potential adverse effects, particularly reproductive tract development in the male fetus. Global distribution of DEHP-contaminated and other adulterated products should prompt governments to become proactive in food safety regulations and chemical testing.

    The prevalence of Salmonella spp. was investigated in 109 wild birds poached in the illegal wildlife trade in Rio de Janeiro; most of them are passerines from Thraupidae family and three from Psittacidae. One strain of Salmonella ser. Typhimurium and two strains of Salmonella ser. Panama were isolated from passerine species and all of them showed resistance to multiple antimicrobial drugs, like ampicillin, ceftriaxone, ceftiofur, tetracycline, gentamicin, nalidixic acid, ciprofloxacin, and enrofloxacin. PFGE showed 100% similarity among the Salmonella ser. Typhimurium strain isolated from a Temminck's seedeater (Sporophila falcirostris) and the strains isolated from a human outbreak, in southern Brazil. The two Salmonella ser. Panama strains isolated from two chestnut-capped blackbirds (Chrysomus ruficapillus) present in the same catch showed the same clonal origin and have never been associated with epizooties and human outbreaks. Potential for dissemination of resistant Salmonella through situations offered by captive management and the isolation of the same strain from wild birds and human sources may become a problem for the conservation of natural populations and to public health.

  17. A neurophysiologically plausible population code model for feature integration explains visual crowding.

    2010-01-01

    Full Text Available An object in the peripheral visual field is more difficult to recognize when surrounded by other objects. This phenomenon is called "crowding". Crowding places a fundamental constraint on human vision that limits performance on numerous tasks. It has been suggested that crowding results from spatial feature integration necessary for object recognition. However, in the absence of convincing models, this theory has remained controversial. Here, we present a quantitative and physiologically plausible model for spatial integration of orientation signals, based on the principles of population coding. Using simulations, we demonstrate that this model coherently accounts for fundamental properties of crowding, including critical spacing, "compulsory averaging", and a foveal-peripheral anisotropy. Moreover, we show that the model predicts increased responses to correlated visual stimuli. Altogether, these results suggest that crowding has little immediate bearing on object recognition but is a by-product of a general, elementary integration mechanism in early vision aimed at improving signal quality.

It has been suggested that crowding results from spatial feature integration necessary for object recognition. However, in the absence of convincing models, this theory has remained controversial. Here, we present a quantitative and physiologically plausible model for spatial integration of orientation signals, based on the principles of population coding. Using simulations, we demonstrate that this model coherently accounts for fundamental properties of crowding, including critical spacing, "compulsory averaging", and a foveal-peripheral anisotropy. Moreover, we show that the model predicts increased responses to correlated visual stimuli. Altogether, these results suggest that crowding has little immediate bearing on object recognition but is a by-product of a general, elementary integration mechanism in early vision aimed at improving signal quality.

  19. Quantum theory as plausible reasoning applied to data obtained by robust experiments.

    2016-05-28

    We review recent work that employs the framework of logical inference to establish a bridge between data gathered through experiments and their objective description in terms of human-made concepts. It is shown that logical inference applied to experiments for which the observed events are independent and for which the frequency distribution of these events is robust with respect to small changes of the conditions under which the experiments are carried out yields, without introducing any concept of quantum theory, the quantum theoretical description in terms of the Schrödinger or the Pauli equation, the Stern-Gerlach or Einstein-Podolsky-Rosen-Bohm experiments. The extraordinary descriptive power of quantum theory then follows from the fact that it is plausible reasoning, that is common sense, applied to reproducible and robust experimental data.

  20. Plausible families of compact objects with a Non Local Equation of State

    We investigate the plausibility of some models emerging from an algorithm devised to generate a one-parameter family of interior solutions for the Einstein equations. It is explored how their physical variables change as the family-parameter varies. The models studied correspond to anisotropic spherical matter configurations having a non local equation of state. This particular type of equation of state with no causality problems provides, at a given point, the radial pressure not only as a function of the density but as a functional of the enclosed matter distribution. We have found that there are several model-independent tendencies as the parameter increases: the equation of state tends to be stiffer and the total mass becomes half of its external radius. Profiting from the concept of cracking of materials in General Relativity, we obtain that those models become more stable as the family parameter increases.

    Full Text Available We address the neutrino radiation of plausible accreting supermassive black holes closely linking to the 5 nuclear components of galaxy samples of Mrk 261/262 and Mrk 266. We predict a time delay before neutrino emission of the same scale as the age of the Universe. The ultrahigh energy neutrinos are produced in superdense protomatter medium via simple (quark or pionic reactions or modified URCA processes (G. Gamow was inspired to name the process URCA after the name of a casino in Rio de Janeiro. The resulting neutrino fluxes for quark reactions are ranging from to , where is the opening parameter. For pionic and modified URCA reactions, the fluxes are and , respectively. These fluxes are highly beamed along the plane of accretion disk, peaked at ultrahigh energies, and collimated in smaller opening angle .

  2. Plausible role of nanoparticle contamination in the synthesis and properties of organic electronic materials

    2016-12-01

    Traceless transition metal catalysis (Pd, Ni, Cu, etc.) is very difficult to achieve. Metal contamination in the synthesized products is unavoidable and the most important questions are: How to control metal impurities? What amount of metal impurities can be tolerated? What is the influence of metal impurities? In this brief review, the plausible origins of nanoparticle contamination are discussed in the framework of catalytic synthesis of organic electronic materials. Key factors responsible for increasing the probability of contamination are considered from the point of view of catalytic reaction mechanisms. The purity of the catalyst may greatly affect the molecular weight of a polymer, reaction yield, selectivity and several other parameters. Metal contamination in the final polymeric products may induce some changes in the electric conductivity, charge transport properties, photovoltaic performance and other important parameters.

    The RNA World hypothesis presupposes that abiotic reactions originally produced nucleotides, the monomers of RNA and universal constituents of metabolism. However, compatible prebiotic reactions for the synthesis of complementary (that is, base pairing) nucleotides and mechanisms for their mutual selection within a complex chemical environment have not been reported. Here we show that two plausible prebiotic heterocycles, melamine and barbituric acid, form glycosidic linkages with ribose and ribose-5-phosphate in water to produce nucleosides and nucleotides in good yields. Even without purification, these nucleotides base pair in aqueous solution to create linear supramolecular assemblies containing thousands of ordered nucleotides. Nucleotide anomerization and supramolecular assemblies favour the biologically relevant β-anomer form of these ribonucleotides, revealing abiotic mechanisms by which nucleotide structure and configuration could have been originally favoured. These findings indicate that nucleotide formation and selection may have been robust processes on the prebiotic Earth, if other nucleobases preceded those of extant life.

  4. Complex adaptive HIV/AIDS risk reduction: Plausible implications from findings in Limpopo Province, South Africa.

    Science.gov (United States)

    Burman, Chris J; Aphane, Marota A

    2016-05-16

    This article emphasises that when working with complex adaptive systems it is possible to stimulate new social practices and/or cognitive perspectives that contribute to risk reduction, associated with reducing aggregate community viral loads. The process of achieving this is highly participatory and is methodologically possible because evidence of 'attractors' that influence the social practices can be identified using qualitative research techniques. Using findings from Limpopo Province, South Africa, we argue that working with 'wellness attractors' and increasing their presence within the HIV/AIDS landscape could influence aggregate community viral loads. While the analysis that is presented is unconventional, it is plausible that this perspective may hold potential to develop a biosocial response - which the Joint United Nations Programme on HIV and AIDS (UNAIDS) has called for - that reinforces the biomedical opportunities that are now available to achieve the ambition of ending AIDS by 2030.

  5. Reciprocity-based reasons for benefiting research participants: most fail, the most plausible is problematic.

    A common reason for giving research participants post-trial access (PTA) to the trial intervention appeals to reciprocity, the principle, stated most generally, that if one person benefits a second, the second should reciprocate: benefit the first in return. Many authors consider it obvious that reciprocity supports PTA. Yet their reciprocity principles differ, with many authors apparently unaware of alternative versions. This article is the first to gather the range of reciprocity principles. It finds that: (1) most are false. (2) The most plausible principle, which is also problematic, applies only when participants experience significant net risks or burdens. (3) Seldom does reciprocity support PTA for participants or give researchers stronger reason to benefit participants than equally needy non-participants. (4) Reciprocity fails to explain the common view that it is bad when participants in a successful trial have benefited from the trial intervention but lack PTA to it.

    2016-04-01

    Cefazolin was demonstrated to exert high reactivity toward permanganate (Mn(VII)), a common oxidant in water pre-oxidation treatment. In this study, five transformation products were found to be classified into three categories according to the contained characteristic functional groups: three (di-)sulfoxide products, one sulfone product and one di-ketone product. Products analyses showed that two kinds of reactions including oxidation of thioether and the cleavage of unsaturated CC double bond occurred during transformation of cefazolin by Mn(VII). Subsequently, the plausible transformation pathways under different pH conditions were proposed based on the identified products and chemical reaction principles. More importantly, the simulation with real surface water matrix indicated that the proposed transformation pathways of cefazolin could be replayed in real water treatment practices.

    Manuka honey, obtained from Leptospermum scoparium flowers in New Zealand, has strong antibacterial properties. In this study, plausible authentication of the manuka honey was inspected by measuring leptosperin, methyl syringate 4-O-β-D-gentiobiose, along with methyl syringate. Despite a gradual decrease in methyl syringate content over 30 days at 50 °C, even at moderate 37 °C, leptosperin remained stable. A considerable correlation between nonperoxide antibacterial activity and leptosperin content was observed in 20 certified manuka honey samples. Leptosperin and methyl syringate in manuka honey and related products were analyzed using HPLC connected with mass spectrometry. One noncertified brand displayed significant variations in the leptosperin and methyl syringate contents between two samples obtained from different regions. Therefore, certification is clearly required to protect consumers from disguised and/or low-quality honey. Because leptosperin is stable during storage and specific to manuka honey, its measurement may be applicable for manuka honey authentication.

    Following his seminal work in 1953, Stanley Miller conducted an experiment in 1958 to study the polymerization of amino acids under simulated early Earth conditions. In the experiment, Miller sparked a gas mixture of CH4, NH3, and H2O, while intermittently adding the plausible prebiotic condensing reagent cyanamide. For unknown reasons, an analysis of the samples was not reported. We analyzed the archived samples for amino acids, dipeptides, and diketopiperazines by liquid chromatography, ion mobility spectrometry, and mass spectrometry. A dozen amino acids, 10 glycine-containing dipeptides, and 3 glycine-containing diketopiperazines were detected. Miller's experiment was repeated and similar polymerization products were observed. Aqueous heating experiments indicate that Strecker synthesis intermediates play a key role in facilitating polymerization. These results highlight the potential importance of condensing reagents in generating diversity within the prebiotic chemical inventory.

    The number of mutated genes in cancer cells is far larger than the number of mutations that drive cancer. The difficulty this creates for identifying relevant alterations has stimulated the development of various computational approaches to distinguishing drivers from bystanders. We develop and apply an ensemble classifier (EC) machine learning method, which integrates 10 classifiers that are publically available, and apply it to breast and ovarian cancer. In particular we find the following: (1) Using both standard and non-standard metrics, EC almost always outperforms single method classifiers, often by wide margins. (2) Of the 50 highest ranked genes for breast (ovarian) cancer, 34 (30) are associated with other cancers in either the OMIM, CGC or NCG database (P plausible.

    Habicht, Jean-Pierre; Martorell, Reynaldo

    2010-02-01

    This article presents evidence that the high-nutrient supplement in the Oriente study (Atole) improved child growth. The evidence is presented at 4 levels. There was a causal effect of the intervention on child length, as assessed by probability analyses of the randomized, controlled trial (P < 0.05). The plausibility analyses, which included an examination of wasting, showed that the nutritional impact was due to the Atole, especially in those who were <3 y old and who suffered from diarrhea. The adequacy analyses revealed excellent biological efficacy of the Atole at the individual level. At the level of the whole population, the efficacy of impact was much less, because many children did not participate fully in the supplementation program. The external validity of the biological impact is likely to be good for populations with similar diets and medical care.

    This article analyses the process of going from recreational use to regular and problematic use of illegal drugs. We present a model containing six career contingencies relevant for young people’s progress from recreational to regular drug use: the closing of social networks, changes in forms...... of parties, intoxication becoming a goal in itself, easier access to drugs, learning to recognise alternative effects of drugs and experiences of loss of control. The analysis shows that these dimensions are at play not only when young people develop a regular drug use pattern but also when they attempt...... to extricate themselves from this pattern. Hence, when regular drug users talk about their future, it is not a future characterised by total abstinence from illegal drugs but a future where they have rolled back their drug use career to the recreational drug use pattern they started out with. Empirically...

  12. The Sarrazin effect: the presence of absurd statements in conspiracy theories makes canonical information less plausible

    2013-07-01

    Full Text Available Reptile prime ministers and flying Nazi saucers—extreme and sometimes off-wall conclusion are common ingredients of conspiracy theories. While individual differences are a common research topic concerning conspiracy theories, the role of extreme statements in the process of acquiring and passing on conspiratorial stories has not been regarded in an experimental design so far. We identified six morphological components of conspiracy theories empirically. On the basis of these content categories a set of narrative elements for a 9/11 story was compiled. These elements varied systematically in terms of conspiratorial allegation, i.e., they contained official statements concerning the events of 9/11, statements alleging to a conspiracy limited in time and space as well as extreme statements indicating an all-encompassing cover-up. Using the method of narrative construction, 30 people were given a set of cards with these statements and asked to construct the course of events of 9/11 they deem most plausible. When extreme statements were present in the set, the resulting stories were more conspiratorial; the number of official statements included in the narrative dropped significantly, whereas the self-assessment of the story’s plausibility did not differ between conditions. This indicates that blatant statements in a pool of information foster the synthesis of conspiracy theories on an individual level. By relating these findings to one of Germany’s most successful (and controversial non-fiction books, we refer to the real-world dangers of this effect.

    To establish a TLC-FTIR method for detection of western medicine phenolphthalein added illegally into anti-obesity and healthcare food. The sample was extracted with anhydrous alcohol. The stationary phase was the GF254 aluminium alloy silica gel plates (10 cm x 20 cm) while the developing solvent was acetic ether: petroleum ether (60-90): methanol = 10: 6: 1. The sample volume was 2 microl. After primary screening by the UV lamp 254nm and self-made 2% NaOH test paper, the preparative technique of TLC was used to separate the component. Then the component was detected by FTIR and compared with the FTIR spectrogram of standard substance. Five of the ten samples contained phenolphthalein with the same testing results by using the TLC scanning and HPLC. The established method is accurate and reliable and can be used for detection of phenolphthalein illegally added into the products.

    2016-01-01

    Environmental insecurity is a source and outcome of biodiversity declines and social conflict. One challenge to scaling insecurity reduction policies is that empirical evidence about local attitudes is overwhelmingly missing. We set three objectives: determine how local people rank risk associated with different sources of environmental insecurity; assess perceptions of environmental insecurity, biodiversity exploitation, myths of nature and risk management preferences; and explore relationships between perceptions and biodiversity exploitation. We conducted interviews (N = 88) with residents of Madagascar's Torotorofotsy Protected Area, 2014. Risk perceptions had a moderate effect on perceptions of environmental insecurity. We found no effects of environmental insecurity on biodiversity exploitation. Results offer one if not the first exploration of local perceptions of illegal biodiversity exploitation and environmental security. Local people's perception of risk seriousness associated with illegal biodiversity exploitation such as lemur hunting (low overall) may not reflect perceptions of policy-makers (considered to be high). Discord is a key entry point for attention.

    2010-10-01

    To report on a unique medical situation after self-obtained use of misoprostol in a country where abortion is illegal. A 29-year-old woman was seen at 12 weeks' gestation with a history of use of 10,800 microg of misoprostol orally and vaginally over the preceding six weeks. She had experienced mild-to-moderate pelvic pain but no vaginal bleeding. Because the pregnancy was intrauterine and viable, surgical termination could not be carried out. The risks of fetal congenital anomalies due to in utero exposure to misoprostol were discussed with the patient. A detailed ultrasonography at 16 weeks' gestation revealed no anomaly. Vaginal delivery at 38 weeks' gestation resulted in the birth of a baby without discernible congenital anomalies. In countries where abortion is illegal, women should be informed about the risks associated with unsupervised self-induced abortion with misoprostol.

    Lightening skin tone is an ancient and well-documented practice, and remains common practice among many cultures. Whitening agents such as corticosteroids, tretinoin and hydroquinone are medically applied to effectively lighten the skin tone of hyperpigmented lesions. However, when these agents are used cosmetically, they are associated with a variety of side-effect. Alternative agents, such as arbutin and its derivatives kojic acid and nicotinamide have been subsequently developed for cosmetic purposes. Unfortunately, some cosmetics contain whitening agents that are banned for use in cosmetic products. This article provides an overview of the mode of action and potential side-effects of cosmetic legal and illegal whitening agents, and the pattern of use of these types of products. Finally, an EU analysis of the health problems due to the presence of illegal products on the market is summarized.

    Full Text Available In this work, we developed an automated system to detect potentially illegal elephant ivory items for sale on eBay. Two law enforcement experts, with specific knowledge of elephant ivory identification, manually classified items on sale in the Antiques section of eBay UK over an 8 week period. This set the “Gold Standard” that we aim to emulate using data-mining. We achieved close to 93% accuracy with less data than the experts, as we relied entirely on metadata, but did not employ item descriptions or associated images, thus proving the potential and generality of our approach. The reported accuracy may be improved with the addition of text mining techniques for the analysis of the item description, and by applying image classification for the detection of Schreger lines, indicative of elephant ivory. However, any solution relying on images or text description could not be employed on other wildlife illegal markets where pictures can be missing or misleading and text absent (e.g., Instagram. In our setting, we gave human experts all available information while only using minimal information for our analysis. Despite this, we succeeded at achieving a very high accuracy. This work is an important first step in speeding up the laborious, tedious and expensive task of expert discovery of illegal trade over the internet. It will also allow for faster reporting to law enforcement and better accountability. We hope this will also contribute to reducing poaching, by making this illegal trade harder and riskier for those involved.

    This paper presents a case study about the detection of illegal dumps from optical satellite images in a large territory falling in the provinces of Naples and Caserta, Southern Italy. This location is also known with the term "Terra dei Fuochi" because in this area is particularly widespread the phenomenon of waste burning and, over the past decades, there have been many landfills of hazardous waste of industrial origin. In addition to the potential damage caused to the environmental matrices, this situation has led to considerable concerns over the health of citizens and a serious economic impact on the agricultural sector. In order to contrast this phenomenon, the government of the Campania Region organized some prevention, monitoring and repression activities. In particular, the monitoring activities are employed by periodic inspection of sites, which are often object of illegal deposits (former quarries, illegal dumps, as well as city and country roads). The periodic inspection is usually performed by patrols of the company SMA Campania (the in-house regional company, specialized in environmental protection), and law enforcement. As part of a project, the remote sensing company MAPSAT srl and CIRA (the Italian Aerospace Research Center), have proposed to SMA Campania to support the periodic monitoring inspection of the patrols, with optical satellite acquisitions. This paper describes the proposed approach, the type of data used, the technical problems encountered and solutions introduced. The periodic monitoring with biannual satellite acquisitions, was effective for both finding new illegal spills and to follow the evolution (in terms of extension) of landfills already found in the past.

On the basis of studying illegal editions of socialists-revolutionaries author has found out their position in relation to elections in Duma of third convocation. In article illegal editions of Siberian socialists-revolutionaries, describing social and party structure of the deputy case, prominent representatives of different fractions, and their behavior within precincts of parliament are quoted. The maintenance of editions of Siberian socialists-revolutionaries, various parties of legislative activity of III Duma, devoted to estimations is in detail stated: statement of state budget, agrarian and working legislation, etc. Estimations of socialists-revolutionaries to P.A. Stolypin’s agrarian transformations are resulted. The reasons of accrued indifferent attitude of population to activity of III Duma are opened. In article it is drawn a conclusion, that Siberian socialists-revolutionaries in illegal press III Dumas dominated over it conservative ideas have adequately enough estimated social and party structure, progovernmental orientation of majority of deputies, slipping to right positions of cadets. In opinion of members of PSR, Russian parliament practically did not represent broad masses of population. Esser’s authors considered not productive legislative activity of Duma, fairly marking, that III Duma has not managed to execute main task – to express political will of population in form of legislation. Therefore in all editions socialists-revolutionaries called citizens to struggle for Constituent assembly which, in their opinion, could resolve all national needs.

    Online sales of pharmaceuticals are a rapidly growing phenomenon. Yet despite the dangers of purchasing drugs over the Internet, sales continue to escalate. These dangers include patient harm from fake or tainted drugs, lack of clinical oversight, and financial loss. Patients, and in particular vulnerable groups such as seniors and minorities, purchase drugs online either naïvely or because they lack the ability to access medications from other sources due to price considerations. Unfortunately, high risk online drug sources dominate the Internet, and virtually no accountability exists to ensure safety of purchased products. Importantly, search engines such as Google, Yahoo, and MSN, although purportedly requiring "verification" of Internet drug sellers using PharmacyChecker.com requirements, actually allow and profit from illicit drug sales from unverified websites. These search engines are not held accountable for facilitating clearly illegal activities. Both website drug seller anonymity and unethical physicians approving or writing prescriptions without seeing the patient contribute to rampant illegal online drug sales. Efforts in this country and around the world to stem the tide of these sales have had extremely limited effectiveness. Unfortunately, current congressional proposals are fractionated and do not address the key issues of demand by vulnerable patient populations, search engine accountability, and the ease with which financial transactions can be consummated to promote illegal online sales. To deal with the social scourge of illicit online drug sales, this article proposes a comprehensive statutory solution that creates a no-cost/low-cost national Drug Access Program to break the chain of demand from vulnerable patient populations and illicit online sellers, makes all Internet drug sales illegal unless the Internet pharmacy is licensed through a national Internet pharmacy licensing program, prohibits financial transactions for illegal online drug

    The 2012 Brazilian Forest Code governs the fate of forests and savannas on Brazil's 394 Mha of privately owned lands. The government claims that a new national land registry (SICAR), introduced under the revised law, could end illegal deforestation by greatly reducing the cost of monitoring, enforcement, and compliance. This study evaluates that potential, using data from state-level land registries (CAR) in Pará and Mato Grosso that were precursors of SICAR. Using geospatial analyses and stakeholder interviews, we quantify the impact of CAR on deforestation and forest restoration, investigating how landowners adjust their behaviors over time. Our results indicate rapid adoption of CAR, with registered properties covering a total of 57 Mha by 2013. This suggests that the financial incentives to join CAR currently exceed the costs. Registered properties initially showed lower deforestation rates than unregistered ones, but these differences varied by property size and diminished over time. Moreover, only 6% of registered producers reported taking steps to restore illegally cleared areas on their properties. Our results suggest that, from the landowner's perspective, full compliance with the Forest Code offers few economic benefits. Achieving zero illegal deforestation in this context would require the private sector to include full compliance as a market criterion, while state and federal governments develop SICAR as a de facto enforcement mechanism. These results are relevant to other tropical countries and underscore the importance of developing a policy mix that creates lasting incentives for sustainable land-use practices.

  12. Deforestation, land conversion and illegal logging in Bangladesh: the case of the Sal (Shorea robusta forests

    Full Text Available Bangladesh, with a forest cover estimated at 17.08% of all land surface area, has experienced massive degradation of its natural resources and a conside­rable change in its land cover. While deforestation in Bangladesh is obviously a complex issue, one important aspect emerges from previous research findings in explaining deforestation: industrialization. This study focuses on the causes of deforestation in Bangladesh, particularly in tropical moist deciduous Sal forests, using multi levels factor analysis framework. Data were collected through questionnaire surveys, formal and informal discussions with local people, expert interviews and literature reviews. The main findings of defore­station framework show that illegal logging and forest land conversion were the ultimate causes of Sal forests deforestation in Bangladesh. Illegal logging is a complex phenomenon and is being patronized by a local syndicate, functio­ning from behind the scenes. On the other hand, land conversion into different commercial activities has direct influence on national policy and the predispo­sing conditions of this country. Therefore, the immediate task of the nation would be to stop illegal logging and land conversion of Sal forests. This can be done by involving all relevant stakeholders in the form of effective forest policy formulation and execution of strict environmental protection law.

    Full Text Available Objective. Determine the infection status with pathogenic Leptospira of one Saguinus oedipus and nine Saguinus leucopus at the Cali Zoo that had been confiscated in Colombia from illegal trade. Materials and methods. A full physical examination, blood work, urinalysis were conducted in all individuals during the reception health check-up, in addition to running the microagglutination test with a pool of 19 serovars, with a starting dilution of 1:50. Results. A high positive titer (≥1:3200 to Leptospira alexanderi serovar manhao in an asymptomatic S. oedipus was detected. All S. leucopus tested negative or less than 1:50. Conclusions. Captive locations have been documented to artificially enhance opportunities to come into contact with contaminated bodily fluids from peridomestic rodents. However, infectious diseases acquired during the illegal transport of wildlife to major metropolitan centers are rarely considered a wildlife conservation or public health threat. Infection with zoonotic pathogens should also be considered an additional threat to endangered wild primates involved in illegal trade, which could hamper reintroduction efforts or other population management procedures for primate species with restricted and fragmented distributions.

    The term "triangle of death" was used for the first time by Senior and Mazza in the journal The Lancet Oncology referring to the eastern area of the Campania Region (Southern Italy) which has one of the worst records of illegal waste dumping practices. In the past decades, many studies have focused on the potential of illegal waste disposal to cause adverse effects on human health in this area. The great heterogeneity in the findings, and the bias in media communication has generated great healthcare doubts, anxieties and alarm. This paper addresses a review of the up-to-date literature on the "triangle of death", bringing together the available information on the occurrence and severity of health effects related to illegal waste disposal. The Scopus database was searched using the search terms "waste", "Campania", "Naples", "triangle of death" and "human biomonitoring". Despite the methodological and sampling heterogeneity between the studies, this review examines the evidence from published data concerning cancer incidence, childhood mortality and birth defects, so that the current situation, knowledge gaps and research priorities can be established. The review aims to provide a contribution to the scientific community, and to respond to the concerns of the general population.

  15. Innovative techniques for estimating illegal activities in a human-wildlife-management conflict.

    Directory of Open Access Journals (Sweden)

    Paul Cross

    Full Text Available Effective management of biological resources is contingent upon stakeholder compliance with rules. With respect to disease management, partial compliance can undermine attempts to control diseases within human and wildlife populations. Estimating non-compliance is notoriously problematic as rule-breakers may be disinclined to admit to transgressions. However, reliable estimates of rule-breaking are critical to policy design. The European badger (Meles meles is considered an important vector in the transmission and maintenance of bovine tuberculosis (bTB in cattle herds. Land managers in high bTB prevalence areas of the UK can cull badgers under license. However, badgers are also known to be killed illegally. The extent of illegal badger killing is currently unknown. Herein we report on the application of three innovative techniques (Randomized Response Technique (RRT; projective questioning (PQ; brief implicit association test (BIAT for investigating illegal badger killing by livestock farmers across Wales. RRT estimated that 10.4% of farmers killed badgers in the 12 months preceding the study. Projective questioning responses and implicit associations relate to farmers' badger killing behavior reported via RRT. Studies evaluating the efficacy of mammal vector culling and vaccination programs should incorporate estimates of non-compliance. Mitigating the conflict concerning badgers as a vector of bTB requires cross-disciplinary scientific research, departure from deep-rooted positions, and the political will to implement evidence-based management.

    Full Text Available We reviewed the data pertaining to the illegal dumping of municipal solid waste in the Republic of Korea for the year 2011 to check for the presence of spatial autoregression of illegal dumping among 224 basic autonomous units with reference to the “Broken Windows Theory.” We found that a pure neighborhood effect exists even after controlling for conventional variables that explain illegal dumping behavior. Interestingly, however, the neighborhood effect is largely offset by so-called relative price effect such that the number of illegal dumping reported in one region is in fact decreased as the price of vinyl bag for MSW in neighboring regions increases, which is seemingly against the implication of the “Broken Windows Theory.”

    To evaluate the diagnostic performance of abdominal radiography in the detection of illegal intracorporeal containers (hereafter, packets), with low-dose computed tomography (CT) as the reference standard. This study was approved by the institutional ethical review board, with written informed consent. From July 2007 to July 2010, 330 people (296 men, 34 women; mean age, 32 years [range, 18-55 years]) suspected of having ingested drug packets underwent supine abdominal radiography and low-dose CT. The presence or absence of packets at abdominal radiography was reported, with low-dose CT as the reference standard. The density and number of packets (≤ 12 or >12) at low-dose CT were recorded and analyzed to determine whether those variables influence interpretation of results at abdominal radiography. Packets were detected at low-dose CT in 53 (16%) suspects. Sensitivity of abdominal radiography for depiction of packets was 0.77 (41 of 53), and specificity was 0.96 (267 of 277). The packets appeared isoattenuated to the bowel contents at low-dose CT in 16 (30%) of the 53 suspects with positive results. Nineteen (36%) of the 53 suspects with positive low-dose CT results had fewer than 12 packets. Packets that were isoattenuated at low-dose CT and a low number of packets (≤12) were both significantly associated with false-negative results at abdominal radiography (P = .004 and P = .016, respectively). Abdominal radiography is mainly limited by low sensitivity when compared with low-dose CT in the screening of people suspected of carrying drug packets. Low-dose CT is an effective imaging alternative to abdominal radiography. © RSNA, 2012.

    Natural and synthetic opioids have efficient analgesic activity but can also be addictive. Thus, the determination of opioids and their metabolites in biological specimens is of interest in clinical and forensic toxicology laboratories. The analysis of drugs in hair provides valuable information on previous chronic drug use and has been successfully applied to the diagnosis of drug abuse, tolerance, compliance and gestational drug exposure. Despite the abuse of prescription opioids along with heroin and other illegal opiates, few studies have been conducted on the simultaneous determination of the broad range of opioids covering those drugs in hair. In the present study, an analytical method for the simultaneous detection in hair of 18 opioids and metabolites considered to have a high abuse risk based on the results of urine drug screening was established and validated using liquid chromatography-tandem mass spectrometry (LC-MS/MS) for the purpose of clinical and forensic applications. The drugs and metabolites were extracted from hair using methanol and analyzed using LC-MS/MS. The validation results proved that the method was selective, accurate and precise with acceptable linearity within calibration ranges. No significant variation was observed by different sources of matrices. The limits of detection and the limits of quantification ranged from 0.05 to 0.25ng/10mg hair and from 0.05 to 0.5ng/10mg hair, respectively. The developed method was successfully applied to 15 hair samples from opioids users. This method will be very useful for monitoring the inappropriate use of opioid drugs.

    Drug abuse is a common problem and growing concern in the United States, and over the past decade, novel or atypical drugs have emerged and have become increasingly popular. Recognition and treatment of new drugs of abuse pose many challenges for health care providers due to lack of quantitative reporting and routine surveillance, and the difficulty of detection in routine blood and urine analyses. Furthermore, street manufacturers are able to rapidly adapt and develop new synthetic isolates of older drugs as soon as law enforcement agencies render them illegal. In this article, we describe the clinical and adverse effects and purported pharmacology of several new classes of drugs of abuse including synthetic cannabinoids, synthetic cathinones, salvia, desomorphine, and kratom. Because many of these substances can have severe or life-threatening adverse effects, knowledge of general toxicology is key in recognizing acute intoxication and overdose; however, typical toxidromes (e.g., cholinergic, sympathomimetic, opioid, etc.) are not precipitated by many of these agents. Medical management of patients who abuse or overdose on these drugs largely consists of supportive care, although naloxone may be used as an antidote for desomorphine overdose. Symptoms of aggression and psychosis may be treated with sedation (benzodiazepines, propofol) and antipsychotics (haloperidol or atypical agents such as quetiapine or ziprasidone). Other facets of management to consider include treatment for withdrawal or addiction, nutrition support, and potential for transmission of infectious diseases.

  7. Drug use and nightlife: more than just dance music

    Full Text Available Abstract Background Research over the last decade has focused almost exclusively on the association between electronic music and MDMA (3,4-Methylenedioxymethamphetamine or "ecstasy" or other stimulant drug use in clubs. Less attention has been given to other nightlife venues and music preferences, such as rock music or southern/funky music. This study aims to examine a broader spectrum of nightlife, beyond dance music. It looks at whether certain factors influence the frequency of illegal drug and alcohol use: the frequency of going to certain nightlife venues in the previous month (such as, pubs, clubs or goa parties; listening to rock music, dance music or southern and funky music; or sampling venues (such as, clubs, dance events or rock festivals. The question of how these nightlife variables influence the use of popular drugs like alcohol, MDMA, cannabis, cocaine and amphetamines is addressed. Methods The study sample consisted of 775 visitors of dance events, clubs and rock festivals in Belgium. Study participants answered a survey on patterns of going out, music preferences and drug use. Odds ratios were used to determine whether the odds of being an illegal substance user are higher for certain nightlife-related variables. Furthermore, five separate ordinal regression analyses were used to investigate drug use in relation to music preference, venues visited during the last month and sampling venue. Results Respondents who used illegal drugs were 2.5 times more likely to report that they prefer dance music. Goa party visitors were nearly 5 times more likely to use illegal drugs. For those who reported visiting clubs, the odds of using illegal drugs were nearly 2 times higher. Having gone to a pub in the last month was associated with both more frequent alcohol use and more frequent illegal substance use. People who reported liking rock music and attendees of rock festivals used drugs less frequently. Conclusions It was concluded that a

    Capturing complete medical knowledge is challenging-often due to incomplete patient Electronic Health Records (EHR), but also because of valuable, tacit medical knowledge hidden away in physicians' experiences. To extend the coverage of incomplete medical knowledge-based systems beyond their deductive closure, and thus enhance their decision-support capabilities, we argue that innovative, multi-strategy reasoning approaches should be applied. In particular, plausible reasoning mechanisms apply patterns from human thought processes, such as generalization, similarity and interpolation, based on attributional, hierarchical, and relational knowledge. Plausible reasoning mechanisms include inductive reasoning, which generalizes the commonalities among the data to induce new rules, and analogical reasoning, which is guided by data similarities to infer new facts. By further leveraging rich, biomedical Semantic Web ontologies to represent medical knowledge, both known and tentative, we increase the accuracy and expressivity of plausible reasoning, and cope with issues such as data heterogeneity, inconsistency and interoperability. In this paper, we present a Semantic Web-based, multi-strategy reasoning approach, which integrates deductive and plausible reasoning and exploits Semantic Web technology to solve complex clinical decision support queries. We evaluated our system using a real-world medical dataset of patients with hepatitis, from which we randomly removed different percentages of data (5%, 10%, 15%, and 20%) to reflect scenarios with increasing amounts of incomplete medical knowledge. To increase the reliability of the results, we generated 5 independent datasets for each percentage of missing values, which resulted in 20 experimental datasets (in addition to the original dataset). The results show that plausibly inferred knowledge extends the coverage of the knowledge base by, on average, 2%, 7%, 12%, and 16% for datasets with, respectively, 5%, 10%, 15%, and

    Residual cardiovascular (CV) risk remains in dyslipidemic patients despite intensive statin therapy, underscoring the need for additional intervention. Eicosapentaenoic acid (EPA), an omega-3 polyunsaturated fatty acid, is incorporated into membrane phospholipids and atherosclerotic plaques and exerts beneficial effects on the pathophysiologic cascade from onset of plaque formation through rupture. Specific salutary actions have been reported relating to endothelial function, oxidative stress, foam cell formation, inflammation, plaque formation/progression, platelet aggregation, thrombus formation, and plaque rupture. EPA also improves atherogenic dyslipidemia characterized by reduction of triglycerides without raising low-density lipoprotein cholesterol. Other beneficial effects of EPA include vasodilation, resulting in blood pressure reductions, as well as improved membrane fluidity. EPA's effects are at least additive to those of statins when given as adjunctive therapy. In this review, we present data supporting the biologic plausibility of EPA as an anti-atherosclerotic agent with potential clinical benefit for prevention of CV events, as well as its cellular effects and molecular mechanisms of action. REDUCE-IT is an ongoing, randomized, controlled study evaluating whether the high-purity ethyl ester of EPA (icosapent ethyl) at 4 g/day combined with statin therapy is superior to statin therapy alone for reducing CV events in high-risk patients with mixed dyslipidemia. The results from this study are expected to clarify the role of EPA as adjunctive therapy to a statin for reduction of residual CV risk.

    2015-12-01

    The purpose of this review is to provide (1) a synopsis on relations of mindfulness with cardiovascular disease (CVD) and major CVD risk factors, and (2) an initial consensus-based overview of mechanisms and theoretical framework by which mindfulness might influence CVD. Initial evidence, often of limited methodological quality, suggests possible impacts of mindfulness on CVD risk factors including physical activity, smoking, diet, obesity, blood pressure, and diabetes regulation. Plausible mechanisms include (1) improved attention control (e.g., ability to hold attention on experiences related to CVD risk, such as smoking, diet, physical activity, and medication adherence), (2) emotion regulation (e.g., improved stress response, self-efficacy, and skills to manage craving for cigarettes, palatable foods, and sedentary activities), and (3) self-awareness (e.g., self-referential processing and awareness of physical sensations due to CVD risk factors). Understanding mechanisms and theoretical framework should improve etiologic knowledge, providing customized mindfulness intervention targets that could enable greater mindfulness intervention efficacy.

    We present the discovery of a plausible super-luminous supernova (SLSN), found in the archival data of Sloan Digital Sky Survey (SDSS) Stripe 82, called PSN 000123+000504. The supernova peaked at M_g<-21.3 mag in the second half of September 2005, but was missed by the real-time supernova hunt. The observed part of the light curve (17 epochs) showed that the rise to the maximum took over 30 days, while the decline time lasted at least 70 days (observed frame), closely resembling other SLSNe of SN2007bi type. Spectrum of the host galaxy reveals a redshift of z=0.281 and the distance modulus of \\mu=40.77 mag. Combining this information with the SDSS photometry, we found the host galaxy to be an LMC-like irregular dwarf galaxy with the absolute magnitude of M_B=-18.2+/-0.2 mag and the oxygen abundance of 12+log[O/H]=8.3+/-0.2. Our SLSN follows the relation for the most energetic/super-luminous SNe exploding in low-metallicity environments, but we found no clear evidence for SLSNe to explode in low-luminosity ...

    In some theories of sentence comprehension, linguistically relevant lexical knowledge, such as selectional restrictions, is privileged in terms of the time-course of its access and influence. We examined whether event knowledge computed by combining multiple concepts can rapidly influence language understanding even in the absence of selectional restriction violations. Specifically, we investigated whether instruments can combine with actions to influence comprehension of ensuing patients of (as in Rayner, Warren, Juhuasz, & Liversedge, 2004; Warren & McConnell, 2007). Instrument-verb-patient triplets were created in a norming study designed to tap directly into event knowledge. In self-paced reading (Experiment 1), participants were faster to read patient nouns, such as hair, when they were typical of the instrument-action pair (Donna used the shampoo to wash vs. the hose to wash). Experiment 2 showed that these results were not due to direct instrument-patient relations. Experiment 3 replicated Experiment 1 using eyetracking, with effects of event typicality observed in first fixation and gaze durations on the patient noun. This research demonstrates that conceptual event-based expectations are computed and used rapidly and dynamically during on-line language comprehension. We discuss relationships among plausibility and predictability, as well as their implications. We conclude that selectional restrictions may be best considered as event-based conceptual knowledge rather than lexical-grammatical knowledge.

  13. From ether to acid: A plausible degradation pathway of glycerol dialkyl glycerol tetraethers

    Glycerol dialkyl glycerol tetraethers (GDGTs) are ubiquitous microbial lipids with extensive demonstrated and potential roles as paleoenvironmental proxies. Despite the great attention they receive, comparatively little is known regarding their diagenetic fate. Putative degradation products of GDGTs, identified as hydroxyl and carboxyl derivatives, were detected in lipid extracts of marine sediment, seep carbonate, hot spring sediment and cells of the marine thaumarchaeon Nitrosopumilus maritimus. The distribution of GDGT degradation products in environmental samples suggests that both biotic and abiotic processes act as sinks for GDGTs. More than a hundred newly recognized degradation products afford a view of the stepwise degradation of GDGT via (1) ether bond hydrolysis yielding hydroxyl isoprenoids, namely, GDGTol (glycerol dialkyl glycerol triether alcohol), GMGD (glycerol monobiphytanyl glycerol diether), GDD (glycerol dibiphytanol diether), GMM (glycerol monobiphytanol monoether) and bpdiol (biphytanic diol); (2) oxidation of isoprenoidal alcohols into corresponding carboxyl derivatives and (3) chain shortening to yield C39 and smaller isoprenoids. This plausible GDGT degradation pathway from glycerol ethers to isoprenoidal fatty acids provides the link to commonly detected head-to-head linked long chain isoprenoidal hydrocarbons in petroleum and sediment samples. The problematic C80 to C82 tetraacids that cause naphthenate deposits in some oil production facilities can be generated from H-shaped glycerol monoalkyl glycerol tetraethers (GMGTs) following the same process, as indicated by the distribution of related derivatives in hydrothermally influenced sediments.

    Chitosan/HI type II salt prepared from crab tendon was investigated by X-ray fiber diffraction. Two polymer chains and 16 iodide ions (I(-)) crystallized in a tetragonal unit cell with lattice parameters of a = b = 10.68(3), c (fiber axis) = 40.77(13) A, and a space group P4(1). Chitosan forms a fourfold helix with a 40.77 A fiber period having a disaccharide as the helical asymmetric unit. One of the O-3... O-5 intramolecular hydrogen bonds at the glycosidic linkage is weakened by interacting with iodide ions, which seems to cause the polymer to take the 4/1-helical symmetry rather than the extended 2/1-helix. The plausible orientations of two O-6 atoms in the helical asymmetric unit were found to be gt and gg. Two chains are running through at the corner and the center of the unit cell along the c-axis. They are linked by hydrogen bonds between N-21 and O-61 atoms. Two out of four independent iodide ions are packed between the corner chains while the other two are packed between the corner and center chains when viewing through the ab-plane. The crystal structure of the salt is stabilized by hydrogen bonds between these iodide ions and N-21, N-22, O-32, O-61, O-62 of the polymer chains.

    4-Aminoimidazole-5-carbonitrile (AICN) was suggested as a prebiotically plausible precursor of purine nucleobases and nucleotides. Although it can be formed in a sequence of photoreactions, AICN is immune to further irradiation with UV-light. We present state-of-the-art multi-reference quantum-chemical calculations of potential energy surface cuts and conical intersection optimizations to explain the molecular mechanisms underlying the photostability of this compound. We have identified the N-H bond stretching and ring-puckering mechanisms that should be responsible for the photochemistry of AICN in the gas phase. We have further considered the photochemistry of AICN-water clusters, while including up to six explicit water molecules. The calculations reveal charge transfer to solvent followed by formation of an H3O(+) cation, both of which occur on the (1)πσ* hypersurface. Interestingly, a second proton transfer to an adjacent water molecule leads to a (1)πσ*/S0 conical intersection. We suggest that this electron-driven proton relay might be characteristic of low-lying (1)πσ* states in chromophore-water clusters. Owing to its nature, this mechanism might also be responsible for the photostability of analogous organic molecules in bulk water.

    A fundamental issue in neuroscience is to understand how neuronal circuits in the cerebral cortex play their functional roles through their characteristic firing activity. Several characteristics of spontaneous and sensory-evoked cortical activity have been reproduced by Infomax learning of neural networks in computational studies. There are, however, still few models of the underlying learning mechanisms that allow cortical circuits to maximize information and produce the characteristics of spontaneous and sensory-evoked cortical activity. In the present article, we derive a biologically plausible learning rule for the maximization of information retained through time in dynamics of simple recurrent neural networks. Applying the derived learning rule in a numerical simulation, we reproduce the characteristics of spontaneous and sensory-evoked cortical activity: cell-assembly-like repeats of precise firing sequences, neuronal avalanches, spontaneous replays of learned firing sequences and orientation selectivity observed in the primary visual cortex. We further discuss the similarity between the derived learning rule and the spike timing-dependent plasticity of cortical neurons.

    The purpose of this review is to examine vitamin D in the context of sport nutrition and its potential role in optimizing athletic performance. Vitamin D receptors (VDR) and vitamin D response elements (VDREs) are located in almost every tissue within the human body including skeletal muscle. The hormonally-active form of vitamin D, 1,25-dihydroxyvitamin D, has been shown to play critical roles in the human body and regulates over 900 gene variants. Based on the literature presented, it is plausible that vitamin D levels above the normal reference range (up to 100 nmol/L) might increase skeletal muscle function, decrease recovery time from training, increase both force and power production, and increase testosterone production, each of which could potentiate athletic performance. Therefore, maintaining higher levels of vitamin D could prove beneficial for athletic performance. Despite this situation, large portions of athletic populations are vitamin D deficient. Currently, the research is inconclusive with regards to the optimal intake of vitamin D, the specific forms of vitamin D one should ingest, and the distinct nutrient-nutrient interactions of vitamin D with vitamin K that affect arterial calcification and hypervitaminosis. Furthermore, it is possible that dosages exceeding the recommendations for vitamin D (i.e. dosages up to 4000-5000 IU/day), in combination with 50 to 1000 mcg/day of vitamin K1 and K2 could aid athletic performance. This review will investigate these topics, and specifically their relevance to athletic performance.

    Recent work in computational neuroscience and cognitive psychology suggests that a set of cells that decay exponentially could be used to support memory for the time at which events took place. Analytically and through simulations on a biophysical model of an individual neuron, we demonstrate that exponentially decaying firing with a range of time constants up to minutes could be implemented using a simple combination of well-known neural mechanisms. In particular, we consider firing supported by calcium-controlled cation current. When the amount of calcium leaving the cell during an interspike interval is larger than the calcium influx during a spike, the overall decay in calcium concentration can be exponential, resulting in exponential decay of the firing rate. The time constant of the decay can be several orders of magnitude larger than the time constant of calcium clearance, and it could be controlled externally via a variety of biologically plausible ways. The ability to flexibly and rapidly control time constants could enable working memory of temporal history to be generalized to other variables in computing spatial and ordinal representations.

    Dual symbioses of vesicular-arbuscular mycorrhizal (VAM) fungi with growth of Momordica charantia were elucidated in terms of plausible mechanism of biosorption in this article. The experiment was conducted in green house and mixed inoculum of the VAM fungi was used in the three replicates. Results demonstrated that the starch contents were the main source of C for the VAM to builds their hyphae. The increased plant height and leaves surface area were explained in relation with an increase in the photosynthetic rates to produce rapid sugar contents for the survival of plants. A decreased in protein, and amino acid contents and increased proline and protease activity in VAM plants suggested that these contents were the main bio-indicators of the plants under biotic stress. The decline in protein may be due to the degradation of these contents, which later on converted into dextrose where it can easily be absorbed by for the period of symbioses. A mechanism of C chemisorption in relation with physiology and morphology of plant was discussed.

    Vitamin D immune-modulating effects were extensively studied, and low levels have been linked with autoimmune diseases. The associations of vitamin D with autoimmune diseases of the liver, and particularly primary biliary cirrhosis (PBC), are yet to be defined. Hence, in this study, serum levels of vitamin D were determined in 79 patients with PBC and 70 age- and sex-matched controls by the LIAISON chemiluminescent immunoassays (DiaSorin-Italy). Clinical and serological parameters of patients were analyzed with respect to vitamin D status. Mean levels of vitamin D were significantly lower among patients with PBC compared with controls (16.8 ± 9 vs. 22.1 ± 9 ng/ml; p = 0.029), and vitamin D deficiency (≤10 ng/ml) was documented in 33% of patients with PBC versus 7% of controls (p plausible roles of vitamin D as a prognostic marker of PBC severity, and as a potential player in this disease pathogenesis. While further studies are awaited, monitoring vitamin D in patients with PBC and use of supplements may be advisable.

  1. Is the de Broglie-Bohm interpretation of quantum mechanics really plausible?

    Science.gov (United States)

    Jung, Kurt

    2013-06-01

    Bohmian mechanics also known as de Broglie-Bohm theory is the most popular alternative approach to quantum mechanics. Whereas the standard interpretation of quantum mechanics is based on the complementarity principle Bohmian mechanics assumes that both particle and wave are concrete physical objects. In 1993 Peter Holland has written an ardent account on the plausibility of the de Broglie-Bohm theory. He proved that it fully reproduces quantum mechanics if the initial particle distribution is consistent with a solution of the Schrödinger equation. Which may be the reasons that Bohmian mechanics has not yet found global acceptance? In this article it will be shown that predicted properties of atoms and molecules are in conflict with experimental findings. Moreover it will be demonstrated that repeatedly published ensembles of trajectories illustrating double slit diffraction processes do not agree with quantum mechanics. The credibility of a theory is undermined when recognizably wrong data presented frequently over years are finally not declared obsolete.

    Full Text Available Agricultural watersheds are affected by changes in climate, land use, agricultural practices, and human demand for energy, food, and water resources. In this context, we analyzed the agricultural, urbanizing Yahara watershed (size: 1345 km², population: 372,000 to assess its responses to multiple changing drivers. We measured recent trends in land use/cover and water quality of the watershed, spatial patterns of 10 ecosystem services, and spatial patterns and nestedness of governance. We developed scenarios for the future of the Yahara watershed by integrating trends and events from the global scenarios literature, perspectives of stakeholders, and models of biophysical drivers and ecosystem services. Four qualitative scenarios were created to explore plausible trajectories to the year 2070 in the watershed's social-ecological system under different regimes: no action on environmental trends, accelerated technological development, strong intervention by government, and shifting values toward sustainability. Quantitative time-series for 2010-2070 were developed for weather and land use/cover during each scenario as inputs to model changes in ecosystem services. Ultimately, our goal is to understand how changes in the social-ecological system of the Yahara watershed, including management of land and water resources, can build or impair resilience to shifting drivers, including climate.

    Combining the temperature and precipitation data from 77 climatological stations and the climatic and hydrological change data from three headstreams of the Tarim River: Hotan, Yarkant, and Aksu in the study area, the plausible association between climate change and the variability of water resources in the Tarim River Basin in recent years was investigated, the long-term trend of the hydrological time series including temperature, precipitation, and streamflow was detected, and the possible association between the El Ni(n)o/Southern Oscillation (ENSO) and these three kinds of time series was tested. The results obtained in this study show that during the past years, the temperature experienced a significant monotonic increase at the speed of 5%, nearly 1℃ rise; the precipitation showed a significant decrease in the 1970s, and a significant increase in the1980s and 1990s, the average annual precipitation was increased with the magnitude of 6.8 mm per decade. A step change occurred in both temperature and precipitation time series around 1986, which may be influenced by the global climate change. Climate change resulted in the increase of the streamflow at the headwater of the Tarim River, but the anthropogenic activities such as over-depletion of the surface water resulted in the decrease of the streamflow at the lower reaches of the Tarim River. The study result also showed that there is no significant association between the ENSO and the temperature, precipitation and streamflow.

    Counterfeit and unapproved medicines are inherently dangerous and can cause patient injury due to ineffectiveness, chemical or biological contamination, or wrong dosage. Growth of the counterfeit medical market in developed countries is mainly attributable to life-style drugs, which are used in the treatment of non-life-threatening and non-painful conditions, such as slimming pills, cosmetic-related pharmaceuticals, and drugs for sexual enhancement. One of the main tasks of health authorities is to identify the exact active pharmaceutical ingredients (APIs) in confiscated drugs, because wrong API compounds, wrong concentrations, and/or the presence of chemical contaminants are the main risks associated with counterfeit medicines. Serious danger may also arise from microbiological contamination. We therefore performed a market surveillance study focused on the microbial burden in counterfeit and unapproved medicines. Counterfeit and unapproved medicines confiscated in Canada and Austria and controls from the legal market were examined for microbial contaminations according to the US and European pharmacopoeia guidelines. The microbiological load of illegal and legitimate samples was statistically compared with the Wilcoxon rank-sum test. Microbial cultivable contaminations in counterfeit and unapproved phosphodiesterase type 5 inhibitors were significantly higher than in products from the legal medicines market (p product in Austria (6% of illegal products tested). Our results show that counterfeit and unapproved pharmaceuticals are not manufactured under the same hygienic conditions as legitimate products. The microbiological contamination of illegal medicinal products often exceeds USP and EP limits, representing a potential threat to consumer health.

    All medical workers have a duty to protect a patient's privacy by law. Civil servants have a duty to prosecute anyone if a crime has been committed and others have the right to prosecute. When medical workers find their patient using illegal drugs, they are in a situation where any possible action they take is either a breach of one of the duties or an abandonment of the right to prosecute. Any worker in this situation should choose to do what will greater benefit society. Medical workers should avoid prosecuting a patient for illegal drug use, so that drug users can seek help. At the same time medical workers should try to put the patient in a situation where the patient's drug use in the future can be treated by the criminal justice system.

    In the aftermath of Hurricane Katrina, the majority of routine activities in New Orleans were disrupted, including the illegal drug market. The large-scale relocation of New Orleans evacuees (NOEs), including many illegal drug users and sellers, to host cities led to a need for new sources of illegal drugs. This need was quickly satisfied by two initially distinct drug markets (1) drug dealers from New Orleans who were themselves evacuees and (2) established drug dealers in the host cities. To be expected, the two markets did not operate indefinitely in parallel fashion. This paper describes the evolving, operational relationship between these two drug markets over time, with a focus on Houston. We analyze the reciprocal evolution of these two markets at two significant points in time: at the beginning of the relocation (2005) and two years later (2007). The overall trend is towards a melding of the two drug markets, as evidenced primarily by decreases in drug-related violence and the cross-fertilization of drug tastes. We describe the process by which the two drug markets are melded over time, in order to seek a better understanding of the social processes by which drug markets in general evolve.

    Cannabis sativa is both an illegal drug and a legitimate crop. The differentiation of illegal drug Cannabis from non-drug forms of Cannabis is relevant in the context of the growth of fibre and seed oil varieties of Cannabis for commercial purposes. This differentiation is currently determined based on the levels of tetrahydrocannabinol (THC) in adult plants. DNA based methods have the potential to assay Cannabis material unsuitable for analysis using conventional means including seeds, pollen and severely degraded material. The purpose of this research was to develop a single nucleotide polymorphism (SNP) assay for the differentiation of "drug" and "non-drug"Cannabis plants. An assay was developed based on four polymorphisms within a 399 bp fragment of the tetrahydrocannabinolic acid (THCA) synthase gene, utilising the snapshot multiplex kit. This SNP assay was tested on 94 Cannabis plants, which included 10 blind samples, and was able to differentiate between "drug" and "non-drug"Cannabis in all cases, while also differentiating between Cannabis and other species. Non-drug plants were found to be homozygous at the four sites assayed while drug Cannabis plants were either homozygous or heterozygous.

    Lead poisoning is preventing the recovery of the critically endangered California condor (Gymnogyps californianus) and lead isotope analyses have demonstrated that ingestion of spent lead ammunition is the principal source of lead poisoning in condors. Over an 8 month period in 2009, three lead-poisoned condors were independently presented with birdshot embedded in their tissues, evidencing they had been shot. No information connecting these illegal shooting events existed and the timing of the shooting(s) was unknown. Using lead concentration and stable lead isotope analyses of feathers, blood, and recovered birdshot, we observed that: i) lead isotope ratios of embedded shot from all three birds were measurably indistinguishable from each other, suggesting a common source; ii) lead exposure histories re-constructed from feather analysis suggested that the shooting(s) occurred within the same timeframe; and iii) two of the three condors were lead poisoned from a lead source isotopically indistinguishable from the embedded birdshot, implicating ingestion of this type of birdshot as the source of poisoning. One of the condors was subsequently lead poisoned the following year from ingestion of a lead buckshot (blood lead 556 µg/dL), illustrating that ingested shot possess a substantially greater lead poisoning risk compared to embedded shot retained in tissue (blood lead ∼20 µg/dL). To our knowledge, this is the first study to use lead isotopes as a tool to retrospectively link wildlife shooting events. - Highlights: • We conducted a case-based analysis of illegal shootings of California condors. • Blood and feather Pb isotopes were used to reconstruct the illegal shooting events. • Embedded birdshot from the three condors had the same Pb isotope ratios. • Feather and blood Pb isotopes indicated that the condors were shot in a common event. • Ingested shot causes substantially greater lead exposure compared to embedded shot.

    Although most often considered independently, subsistence hunting, domestic trade, and international trade as components of illegal wildlife use (IWU) may be spatially correlated. Understanding how and where subsistence and commercial uses may co-occur has important implications for the design and implementation of effective conservation actions. We analyzed patterns in the joint geographical distribution of illegal commercial and subsistence use of multiple wildlife species in Venezuela and evaluated whether available data were sufficient to provide accurate estimates of the magnitude, scope, and detectability of IWU. We compiled records of illegal subsistence hunting and trade from several sources and fitted a random-forest classification model to predict the spatial distribution of IWUs. From 1969 to 2014, 404 species and 8,340,921 specimens were involved in IWU, for a mean extraction rate of 185,354 individuals/year. Birds were the most speciose group involved (248 spp.), but reptiles had the highest extraction rates (126,414 individuals/year vs. 3,133 individuals/year for birds). Eighty-eight percent of international trade records spatially overlapped with domestic trade, especially in the north and along the coast but also in western inland areas. The distribution of domestic trade was broadly distributed along roads, suggesting that domestic trade does not depend on large markets in cities. Seventeen percent of domestic trade records overlapped with subsistence hunting, but the spatial distribution of this overlap covered a much larger area than between commercial uses. Domestic trade seems to respond to demand from rural more than urban communities. Our approach will be useful for understanding how IWU works at national scales in other parts of the world. © 2016 Society for Conservation Biology.

    The aim of this study was to compare three groups of Brazilian psychoactive substance (PAS) abuse patients (crack cocaine users, cocaine snorters, and non-cocaine PAS users) in terms of psychiatric comorbidities and severity of psychosocial problems. A cross-sectional, multi-center study was conducted at five Brazilian research centers. A total of 738 current PAS abusers seeking specialized treatment (outpatient and inpatient clinics) were assessed using the sixth version of the Addiction Severity Index (ASI-6): 293 patients using crack cocaine were compared with 126 using powder cocaine and 319 using non-cocaine PAS (mostly alcohol and marijuana). Psychiatric comorbidities were assessed in a smaller sample (290 cases), originating from three of the centers, using the Mini International Neuropsychiatric Interview Plus (MINI-Plus). Crack and powder cocaine users were significantly younger than non-cocaine PAS users (31.1 ± 8.1 and 32.9 ± 8.8 vs. 42.4 ± 12, respectively; p disorder (25%) than powder cocaine (9%) and non-cocaine PAS users (9%), even when adjusted for confounding factors (Pr = 2.6; 95% CI 1.10-6.40). According to ASI-6 summary scores, crack users presented a significantly higher rate of occupational, family, and legal problems and reported more illegal and violent activities such as burglary and theft (23%) and threatening or assaulting (32%) than non-cocaine PAS users. Our findings, combined with the recent increase observed in the prevalence of crack use in Brazil, highlight the severity of psychiatric symptoms and psychosocial problems related to this powerful drug and corroborate the already suggested association between crack/cocaine, violence, and legal problems. Treatment programs for crack users should routinely consider the possibility of associated psychiatric comorbidities, such as antisocial personality disorder, which may affect treatment outcomes.

    Full Text Available This article analyzes the illegal migration of Romanians in 1989. Depression and human rights violation favor working class dissatisfaction about communist regime. The Romanians tries to leave the country against any danger, with the goal to establish in Western Europe or North America. Based on the data collected from The National Council for the Securitate Archives (N=1.962, our research establish the socio-demographic profile of Romanian migrant in 1989. Statistical analyses suggested that the workers represent majority of migrants and they leave Romania from economic reasons, not for political ones.

    Full Text Available In this article, illegal Jewish Migration to Palestine and the Manner of the Ottoman Empire towards this migration throughout the second half of the 19th century will be shed into light. The migration movement to the Palestinian lands for Zionist purposes covers a period for the Jewish people full of patience, seriousness and sacrifices. Especially the rich Jews living in Europe and America supplied the money flow through the companies they set up and the Jews who were the idea-father of the Zionism made great efforts to get the Jewish people all over the world to migrate to the holy lands.

    There are a quarter of a million or more foreign laborers that work in Israel. Most of these foreign laborers lack a work permit and medical insurance. Hence, this population has low access to ambulatory medical care, with obvious consequences. When being treated in the public hospital, these illegal immigrants and the doctors caring for them face many problems, both practical and ethical. We review a number of cases illustrating some of these problems, and the danger they present to the work ethics and integrity of the public medical facility.

    Full Text Available A proper analysis of the essential elements that comprise a criminal offense that falls under the purview of medical negligence is fundamental in order to rule, in justice, cases of alleged malpractice. It is necessary to properly distinguish between accusations of illegality and those of guilt. Open legal essays and precedents about such illicit acts provide judges with great latitude in determining when acts are consistent or not with standard care. This power mandates that judges should ground their convictions on objective infringements of the law rather than subjective criteria.

  3. Flux-based transport enhancement as a plausible unifying mechanism for auxin transport in meristem development.

    Directory of Open Access Journals (Sweden)

    2008-10-01

    Full Text Available Plants continuously generate new organs through the activity of populations of stem cells called meristems. The shoot apical meristem initiates leaves, flowers, and lateral meristems in highly ordered, spiralled, or whorled patterns via a process called phyllotaxis. It is commonly accepted that the active transport of the plant hormone auxin plays a major role in this process. Current hypotheses propose that cellular hormone transporters of the PIN family would create local auxin maxima at precise positions, which in turn would lead to organ initiation. To explain how auxin transporters could create hormone fluxes to distinct regions within the plant, different concepts have been proposed. A major hypothesis, canalization, proposes that the auxin transporters act by amplifying and stabilizing existing fluxes, which could be initiated, for example, by local diffusion. This convincingly explains the organised auxin fluxes during vein formation, but for the shoot apical meristem a second hypothesis was proposed, where the hormone would be systematically transported towards the areas with the highest concentrations. This implies the coexistence of two radically different mechanisms for PIN allocation in the membrane, one based on flux sensing and the other on local concentration sensing. Because these patterning processes require the interaction of hundreds of cells, it is impossible to estimate on a purely intuitive basis if a particular scenario is plausible or not. Therefore, computational modelling provides a powerful means to test this type of complex hypothesis. Here, using a dedicated computer simulation tool, we show that a flux-based polarization hypothesis is able to explain auxin transport at the shoot meristem as well, thus providing a unifying concept for the control of auxin distribution in the plant. Further experiments are now required to distinguish between flux-based polarization and other hypotheses.

  4. Identifying and reducing potentially wrong immunoassay results even when plausible and "not-unreasonable".

    The primary role of the clinical laboratory is to report accurate results for diagnosis of disease and management of illnesses. This goal has, to a large extent been achieved for routine biochemical tests, but not for immunoassays which remained susceptible to interference from endogenous immunoglobulin antibodies, causing false, and clinically misleading results. Clinicians regard all abnormal results including false ones as "pathological" necessitating further investigations, or concluding iniquitous diagnosis. Even more seriously, "false-negative" results may wrongly exclude pathology, thus denying patients' necessary treatment. Analytical error rate in immunoassays is relatively high, ranging from 0.4% to 4.0%. Because analytical interference from endogenous antibodies is confined to individuals' sera, it can be inconspicuous, pernicious, sporadic, and insidious because it cannot be detected by internal or external quality assessment procedures. An approach based on Bayesian reasoning can enhance the robustness of clinical validation in highlighting potentially erroneous immunoassay results. When this rational clinical/statistical approach is followed by analytical affirmative follow-up tests, it can help identifying inaccurate and clinically misleading immunoassay data even when they appear plausible and "not-unreasonable." This chapter is largely based on peer reviewed articles associated with and related to this approach. The first section underlines (without mathematical equations) the dominance and misuse of conventional statistics and the underuse of Bayesian paradigm and shows that laboratorians are intuitively (albeit unwittingly) practicing Bayesians. Secondly, because interference from endogenous antibodies is method's dependent (with numerous formats and different reagents), it is almost impossible to accurately assess its incidence in all differently formulated immunoassays and for each analytes/biomarkers. However, reiterating the basic concepts

    We present the discovery of a plausible super-luminous supernova (SLSN), found in the archival data of Sloan Digital Sky Survey (SDSS) Stripe 82, called PSN 000123+000504. The supernova (SN) peaked at m {sub g} < 19.4 mag in the second half of 2005 September, but was missed by the real-time SN hunt. The observed part of the light curve (17 epochs) showed that the rise to the maximum took over 30 days, while the decline time lasted at least 70 days (observed frame), closely resembling other SLSNe of SN 2007bi type. The spectrum of the host galaxy reveals a redshift of z = 0.281 and the distance modulus of μ = 40.77 mag. Combining this information with the SDSS photometry, we found the host galaxy to be an LMC-like irregular dwarf galaxy with an absolute magnitude of M{sub B} = –18.2 ± 0.2 mag and an oxygen abundance of 12+log [O/H]=8.3±0.2; hence, the SN peaked at M {sub g} < –21.3 mag. Our SLSN follows the relation for the most energetic/super-luminous SNe exploding in low-metallicity environments, but we found no clear evidence for SLSNe to explode in low-luminosity (dwarf) galaxies only. The available information on the PSN 000123+000504 light curve suggests the magnetar-powered model as a likely scenario of this event. This SLSN is a new addition to a quickly growing family of super-luminous SNe.

  6. Bio-physically plausible visualization of highly scattering fluorescent neocortical models for in silico experimentation

    2017-02-15

    Background We present a visualization pipeline capable of accurate rendering of highly scattering fluorescent neocortical neuronal models. The pipeline is mainly developed to serve the computational neurobiology community. It allows the scientists to visualize the results of their virtual experiments that are performed in computer simulations, or in silico. The impact of the presented pipeline opens novel avenues for assisting the neuroscientists to build biologically accurate models of the brain. These models result from computer simulations of physical experiments that use fluorescence imaging to understand the structural and functional aspects of the brain. Due to the limited capabilities of the current visualization workflows to handle fluorescent volumetric datasets, we propose a physically-based optical model that can accurately simulate light interaction with fluorescent-tagged scattering media based on the basic principles of geometric optics and Monte Carlo path tracing. We also develop an automated and efficient framework for generating dense fluorescent tissue blocks from a neocortical column model that is composed of approximately 31000 neurons. Results Our pipeline is used to visualize a virtual fluorescent tissue block of 50 μm3 that is reconstructed from the somatosensory cortex of juvenile rat. The fluorescence optical model is qualitatively analyzed and validated against experimental emission spectra of different fluorescent dyes from the Alexa Fluor family. Conclusion We discussed a scientific visualization pipeline for creating images of synthetic neocortical neuronal models that are tagged virtually with fluorescent labels on a physically-plausible basis. The pipeline is applied to analyze and validate simulation data generated from neuroscientific in silico experiments.

    The development and application of the “digital mine” concept in China depends heavily upon the use of remote sensing data as well as domestic expertise and awareness.Illegal mining of mineral resources has been a serious long term problem frustrating the Xishimen Iron Ore Mine management.This mine is located in Wu'an county in Hebei province,China.Illegal activities have led to enormous economic losses by interfering with the normal operation of the Xishimen mine and have ruined the surrounding environment and the stability of the Mahe riverbed the crosses the mined area.This paper is based on field reconnaissance taken over many years around the mine area.The ground survey data are integrated with Differential Synthetic Aperture Radar Interferometry (D-InSAR) results from ALOS/PALSAR data to pinpoint mining locations.By investigating the relationship between the resulting interferometric deformation pattern and the mining schedule,which is known a priori,areas affected by illegal mining activities are identified.To some extent these areas indicate the location of the illegal site.The results clearly demonstrate D-InSAR's ability to cost-effectively monitor illegal mining activities.

    This was a retrospective review and descriptive analysis of the findings from the medical screening examinations conducted on the illegal migrants from Fujian Province of China (n = 589) who arrived on four boats on the West Coast of Canada between June 14 and September 9, 1999. The Canadian Navy conducted a screening medical exam of the illegal migrants, with Health Canada and Citizenship and Immigration Canada providing suggestions on the format of the exam. The illegal Chinese migrants were predominantly young, male adults. The most prevalent medical conditions detected were dermatological (55.2%), dental problems (25%), trauma (9.2%), urogenital (7.6%), and head/neck (6.6%). Recently induced trauma was more prevalent among females (20.5%) than males (6.5%). One case of community-acquired pneumonia was identified and later diagnosed as active pulmonary tuberculosis. Physicians dealing with illegal migrants should look for unusual physical findings and have a higher clinical suspicion regarding infectious diseases (tuberculosis, scabies) and abuse. Future encounters with illegal migrants should include standardized immigration screening exams, with adequate history taking and follow-up.

    Psychedelic drugs such as LSD and psilocybin are often claimed to be capable of inducing life-changing experiences described as mystical or transcendental, especially if high doses are taken. The present study examined possible enduring effects of such experiences by comparing users of psychedelic drugs (n = 88), users of nonpsychedelic illegal drugs (e.g., marijuana, amphetamines) (n = 29) and non illicit drug-using social drinkers (n = 66) on questionnaire measures of values, beliefs and emotional empathy. Samples were obtained from Israel (n = 110) and Australia (n = 73) in a cross-cultural comparison to see if values associated with psychedelic drug use transcended culture of origin. Psychedelic users scored significantly higher on mystical beliefs (e.g., oneness with God and the universe) and life values of spirituality and concern for others than the other groups, and lower on the value of financial prosperity, irrespective of culture of origin. Users of nonpsychedelic illegal drugs scored significantly lower on a measure of coping ability than both psychedelic users and non illicit drug users. Both groups of illegal drug users scored significantly higher on empathy than non illicit drug users. Results are discussed in the context of earlier findings from Pahnke (1966) and Doblin (1991) of the transformative effect of psychedelic experiences, although the possibility remains that present findings reflect predrug characteristics of those who chose to take psychedelic drugs rather than effects of the drugs themselves.

    The recent implementation of the dual energy technology on CT-scanners has opened new perspectives in tissue and material characterization. This study aims to evaluate whether dual energy CT can be used to assess the concentration of cocaine of intra-intestinal illegal packets. The study was approved by the institutional review board of our institution (CER 13_027_R). From November 2010 to May 2013, all consecutive conveyors in whom a low-dose abdominal CT (LDCT) revealed the presence of illegal intra-corporeal drug packets underwent a dual energy CT series (gemstone spectral imaging) targeted on one container. The mean radiological density (HU) of these packets was measured on the LDCT series, and on the monochromatic dual energy series, at 40 and 140 keV. The difference between the HU at 40 and 140 keV was reported as ∆HU. The effective atomic number Z(eff) was also measured on the monochromatic series. A chemical analysis was performed after expulsion to select cocaine containing packets, and to determine their cocaine concentrations. A correlation analysis was performed between HU, ∆HU and Z(eff), with regard to the percentage of cocaine. Fifty-four cocaine conveyors were included. The mean cocaine content of the packets was 36.8% (range 11.2-80, SD 15.4), the mean radiologic density 105 HU, the mean Z(eff) 8.7 and the mean ∆HU 163. The cocaine content was correlated with the ∆HU (0.57, p 200 was 0.9 (9 of 10) sensitive and 0.82 (36 of 44) specific to predict a cocaine concentration higher than 50%. Measuring ∆HU or Z(eff) on dual energy monochromatic CT series can be used to detect ingested packets with cocaine concentration >50%.

    A fast screening method was established for the simultaneous determination of 24 sedative hypnotics illegally added in improving sleep health foods by high performance liquid chromatography-ion trap mass spectrometry (HPLC-IT MS). The method was based on the sonication assisted extraction of the improving sleep health food samples using methanol. The extract was then filtrated with 0.45 µm filter membrane and the filtrate was separated on a Phenomenex Luna C18 column with isocratic elution at a flow rate of 0.3 mL/min. A binary mobile phase was 0.05% (v/v) formic acid (solvent A)-methanol/acetonitrile (15:25, v/v, solvent B). The electrospray ionization (ESI) source in positive ion mode or negative ion mode was used to scan MS1-MS3 spectra for the 24 sedative hypnotics. The MS2 and MS3 spectra were used for qualitative analysis of samples. The calibration graphs were linear in their concentration ranges with the correlation coefficients (r2) more than 0.999. The limits of detection (LODs) were 4.0-446.6 µg/L. The recoveries for all the drugs in the improving sleep health foods were 88.6%-110.3% with the relative standard deviations no more than 9.8% at three spiked levels. Twenty-seven batches of the improving sleep health foods were tested. Melatonin was found in eighteen batches. The method is fast, specific, sensitive, easy and suitable for fast screening of 24 sedative hypnotics illegally added in improving sleep health foods.

    Full Text Available As the use of illegal drugs has reached epidemic proportions in schools, educational leaders in the United States have turned to drug testing in attempting to maintain learner discipline. To this end, the United States Supreme Court has addressed the issue twice in the past eight years. In 1995, the Court permitted drug testing in Acton v. Vernonia School District 47J. More recently, in Board of Education of Independent School District No. 92 of Pottawatomie v. Earls (2002, the Court upheld suspicionless drug testing of learners who wished to participate in extracurricular activities. Even though drug testing has yet to emerge as an issue in South Africa, Earls is significant for educational leaders and policy makers in South Africa since it involves concerns under the National Policy on Privacy. More specifically, under Items 20 and 21 of the South African National Policy on the Management of Drug Abuse (SA, 1996b searches and drug testing should only be used where there is reasonable suspicion, the same standard applied by American courts. However, unlike the United States, the South African policy prohibits random searches and/or drug testing. Thus, due to constitutional and educational issues that drug testing raises, a timely discussion of this matter should be of interest to educational leaders and policy makers in South Africa.

    Illegal, Unreported and Unregulated fishing has had a major role in the overexploitation of global fish populations. In response, international regulations have been imposed and many fisheries have been 'eco-certified' by consumer organizations, but methods for independent control of catch certificates and eco-labels are urgently needed. Here we show that, by using gene-associated single nucleotide polymorphisms, individual marine fish can be assigned back to population of origin with unprecedented high levels of precision. By applying high differentiation single nucleotide polymorphism assays, in four commercial marine fish, on a pan-European scale, we find 93-100% of individuals could be correctly assigned to origin in policy-driven case studies. We show how case-targeted single nucleotide polymorphism assays can be created and forensically validated, using a centrally maintained and publicly available database. Our results demonstrate how application of gene-associated markers will likely revolutionize origin assignment and become highly valuable tools for fighting illegal fishing and mislabelling worldwide.

    Full Text Available Unregulated selling practices, bad storage habits and the use of illegal pesticides in Bolivia are widespread, with increasing negative consequences on public health and the environment. The present study describes the selling, storage and use of legal, illegal and obsolete pesticides among pesticide retailers and farmers in Bolivia. A cross-sectional study was conducted on 191 pesticide-using farmers and 40 pesticide retailers. Data were gathered in 2009 in La Paz County, Bolivia. A questionnaire was used to evaluate pesticide handling practices and observational data on pesticide stocks and storage was assessed through direct visits on site. Banned, outdated and highly toxic pesticides were found stored on most smallholder farms. A mean of 299 g of pesticides was found on each farm, of which 60% were obsolete. Knowledge on pesticide toxicity and safe handling practices were lacking among both retailers and farmers, and poisonings were frequently reported. Significant figures of obsolete pesticides were found outside of the officially recognized dumping sites. This underlines the necessity of including the small but numerous amounts of pesticides stored at farms, when calculating a country’s total amount of obsolete pesticides. Better regulations of imports, sale and storage and an improved use of safety measures when handling pesticides needs to be urgently addressed.

  17. Coyotes, Concessions and Construction Companies: Illegal Water Markets and Legally Constructed Water Scarcity in Central Mexico

    Directory of Open Access Journals (Sweden)

    Nadine Reis

    2014-10-01

    Full Text Available Many regions of (semiarid Mexico, such as the Valley of Toluca, face challenges due to rapid growth and the simultaneous overexploitation of groundwater. The water reform of the 1990s introduced individual water rights concessions granted through the National Water Commission (Comisión Nacional del Agua, or CONAGUA. Since then, acquiring new water rights in officially 'water-scarce' aquifers is only possible through official rights transmissions from users ceding their rights. With the law prohibiting the sale of water rights, a profitable illegal market for these rights has emerged. The key actor in the water rights allocation network is the coyote, functioning as a broker between a people wanting to cede water rights and those needing them, and b the formal and informal spheres of water rights allocation. Actors benefitting from water rights trading include the coyote and his 'working brigades', water users selling surplus rights, and (senior and lower-level staff in the water bureaucracy. The paper concludes that legally constructed water scarcity is key to the reproduction of illegal water rights trading. This has important implications regarding the current push for expanding regularisation of groundwater extraction in Mexico. Currently, regularisation does not counter overexploitation, while possibly leading to a de facto privatisation of groundwater.

    Full Text Available The United States has always been a great migratory magnet. This article analyzes various aspects of the phenomenon of illegal immigration by centering on the U.S. experience, with the objective of extracting lessons that might be applicable to the Spanishpolicy regarding immigration. Shown first are both the historical evolution of U.S. migratory legislation in this century and the consequences which illegal immigration has had upon the citizen population in the recent years. Next, the paper looks at the INS (Immigration and Naturalization Service –the agency charged to implement immigration laws– to analyze how its function has developed into what it is. Basically, the INS has employed two types of dissuasive strategies: one called border policies and the other, interior policies. While the U.S. assigns a greater volume of resources to its border policies, the success of these has been limited. It is then examined why, despite the ineffectiveness of these policies, they continue to be implemented. The result of this analysis indicates that, even though their effectiveness is low, the policies may quite be profitable for the agency entrusted to carry them out. To finish, the paper looks at the characteristics of the Spanish case and makes recommendations based on the experience in the United States.

    Despite being protected by both international and national regulations, pangolins are threatened by illegal trade. Here we report mitochondrial DNA identification and haplotype richness estimation, using 239 pangolin scale samples from two confiscations in Hong Kong. We found a total of 13 genetically distinct cytochrome c oxidase I (COI) haplotypes in two confiscations (13 and ten haplotypes respectively, with ten shared haplotypes between confiscations). These haplotypes clustered in two distinct clades with one clade representing the Sunda pangolin (Manisjavanica). The other clade did not match with any known Asian pangolin sequences, and likely represented a cryptic pangolin lineage in Asia. By fitting sample coverage and rarefaction/regression models to our sample data, we predicted that the total number of COI haplotypes in two confiscations were 14.86 and 11.06 respectively, suggesting that our sampling caught the majority of haplotypes and that we had adequately characterized each confiscation. We detected substantial sequence divergence among the seized scales, likely evidencing that the Sunda pangolins were harvested over wide geographical areas across Southeast Asia. Our study illustrates the value of applying DNA forensics for illegal wildlife trade monitoring.

  20. The Role of Social Media in Community Building for Illegal Vietnamese Migrant Workers in Thailand

    2016-05-01

    Full Text Available Vietnamese migrant workers in Thailand along with those from other neighboring countries increasingly play an important role in the local economy. They are also an important source of income for the sending country. However, the illegal status of Vietnamese workers in Thailand presents a number of challenges both individually and communally. This paper explores the difficulties faced by Vietnamese who come to this country to make a living. These difficulties arise not only from having to work illegally, but also from social, cultural, and linguistic barriers that they must confront in the Thai environment. It proposes that these difficulties are partially made easier by the availability of social media, in particular Facebook. The prevalent use of Facebook among Vietnamese migrant workers in Thailand helps to build community by connecting family, friends, and faith groups together, by serving as a resource for important news and information pertaining to legal and social issues that directly affect them, and by serving as a means for community support in time of crisis. This paper argues that social media, as seen in the case of Vietnamese migrant workers, can effectively be used by community and religious leaders to provide various types of support for migrant workers living in diaspora.
