    This study clarified the suitability of fishes caught from illegal fish farms to human consumption and their hazards to public health. For this purpose, the concentrations of some metals (Al, Cd, Pb, Hg and Ni) in water and Nile tilapia (Oreochromis niloticus) fish samples collected from an illegal fish farm, in addition to pathological conditions of the fish tissues, were examined. The illegal farm water was found to be heavily polluted with metals which far exceeded the permissible limits. It was found that metals accumulated in tissues of O. niloticus in concentrations higher than those of farm water. Kidney of O. niloticus contained the highest concentrations of the detected metals, while muscle and skin contained the lowest concentrations. The examination of fish tissues revealed various histopathological lesions which related directly to the pollution of the illegal farm water. Moreover, metals levels in O. niloticus muscle were higher than the maximum permissible levels for human consumption. Consequently, the flesh of fishes from the illegal farms could be considered hazardous to human health. Therefore, warning against eating fish caught from the illegal fish farms should be announced. Moreover, removal of such illegal fish farms is necessary for the public health protection. Copyright © 2012 Elsevier Inc. All rights reserved.

  2. 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.

  3. Coping with illegal immigrants.

    The annual net flow of illegal immigrants into the US is around 500,000/year which has increased tenfold over the last 15 years; these people, unprotected by US law, are targets of exploitation. Unless a restrictive policy is put into practice for illegal and legal immigrants the flow will accelerate, creating domestic pressures. A package proposed by a Presidential Task Force in 1982 proposed: 1) there be better border patrols and stricter laws regarding hiring of illegals, 2) issuing a counterfeit-resistant social security card, 3) conditional amnesty for some illegal immigrants already in the US, 4) a small increase in the number of legal immigrants allowed into the US from Mexico, and 5) a limited guest worker program. These ideas differed in some respects from those of an earlier Select Committee on Immigration. Guest worker programs in other countries are described. In July 1982 President Reagan faced 3 policy options: 1) he could ignore his Task Force's ideas and use a large guest worker program, legalizing and continuing the inflow of cheap labor; 2) he could adopt the recommendations and get a new, tougher policy initiated; or 3) he could allow the issue to abort itself. He adopted the 3rd option, a policy package with little internal force which he will not pursue vigorously. Any serious effort to achieve a more serious immigration policy must include 4 elements: 1) a tough set of employer sanctions, 2) a foolproof worker identification card system, 3) better border control, and 4) an amnesty program. These 4 measures are interrelated; if 1 fails, the policy ceases to achieve its goals. This 4-point program would have the advantage of maintaining a short-term "safety-valve" for those countries which are the sources of illegal migration.

    Border enforcement of immigration laws attempts to raise the costs of illegal immigration, while interior enforcement also lowers the benefits. Border and interior enforcement therefore reduce the net benefits of illegal immigration and should lower the probability that an individual will decide to migrate. While some empirical studies find that border and interior enforcement serve as significant deterrents to illegal immigration, immigration enforcement is costly and carries significant uni...

    The stellar sup 7 Be(p, gamma) sup 8 B reaction rate has the largest uncertainty among all nuclear reaction rates in the standard solar model. However, the solar neutrino flux predicted for the majority of proposed and existing solar neutrino detectors is directly dependent on the rate of sup 7 Be(p, gamma) sup 8 B reaction. The existing solar neutrino detectors measure rate of sup 8 B decay neutrinos that is too low. This constitutes largely the solar neutrino problem. Existing measurements of the sup 7 Be(p, gamma) sup 8 B reaction rate disagree with one another, indicating the need for more precise experiments. To provide the required targets a new procedure for sup 7 Be production, separation and target manufacturing has been developed. First, a lithium target has been designed for sup 7 Be production at TRIUMF's 13 MeV cyclotron. The lithium target has been extensively tested at 50 mu A proton beam current yielding 8.1 MBq/mu A h of sup 7 Be. An adsorption filtration technique has been developed for sup ...

    Some fusion targets designed to be driven by 0.35 to 1 μm laser light are glass spheres coated with layers of various materials such as hydrocarbons, fluorocarbons, beryllium, copper, gold, platinum, etc. The glass shell, which is filled with gas, liquid or solid deuterium-tritium fuel, must have remarkably good surface and wall thickness uniformity. Methods for depositing the various materials will be discussed. They include plasma polymerization, electro-deposition, sputtering and evaporation. Many of the difficulties encountered in the coating processes are the result of coating on free spheres with very small radii - 35 to 500 micrometers. Several means of overcoming the problems will be described and experimental results presented

    An interrelation between consumption of illegal drugs and committing an indictable offence has been repeatedly discussed in literature. In a retrospective study serum concentrations of illegal and legal drugs as well as data originating from police reports and examinations by physicians taking blood from individuals being suspected to be under the influence of drugs were evaluated. Results from 4816 cases were available. Property offences were the most frequent type (36%) as well as consumption of cannabinoids (55%). Psychophysiological conditions of consumers were compared with according serum concentrations. Close correlations between stimulating drugs and violence associated crime could not be found. Stimulated as well as sedated behaviour occurring following the consumption of various drugs might be the reason for no clear correlation between types of offence and consumed illegal or legal drugs in this study.

    1999-01-01

    In order to validate the computations of stress generated in the target container by the sudden input of a large amount of power in the liquid metal of a high-power spallation target, first experimental investigations were carried out in an international collaboration. Temperature and beam profile measurements showed that up to 61% of the incoming beam power was deposited in the target. The spatial power distribution was reconstructed from the experimental data. A computational model with consideration of fluid-structure interface was employed to simulate the pressure waves in the liquid and the resulting dynamic stress on the container. The maximum stress on the container was found to be 13.6 MP. Although experimental data are still very preliminary, a comparison of the measured stress and deformation data with the computational results showed reasonable agreement in the amplitudes, which are the most important data for engineering design. Although the methods developed to measure the strain on the target su...

    To improve general understanding of biochemical mechanisms in the field of uranium toxicology, the identification of protein targets needs to be intensified. Immobilized metal affinity chromatography (IMAC) has been widely developed as a powerful tool for capturing metal binding proteins from biological extracts. However uranyl cations (UO{sub 2}{sup 2+}) have particular physico-chemical characteristics which prevent them from being immobilized on classical metal chelating supports. We report here on the first development of an immobilized uranyl affinity chromatography method, based on the cation-exchange properties of amino-phosphonate groups for uranyl binding. The cation distribution coefficient and loading capacity on the support were determined. Then the stability of the uranyl-bonded phase under our chromatographic conditions was optimized to promote affinity mechanisms. The successful enrichment of uranyl binding proteins from human serum was then proven using proteomic and mass spectral analysis. (authors)

The profiles include such topics as industry structure, process technology, materials and recycling flow, and future trends. Chapter 4 specifically covers the evaluation of recycling targets for the ferrous, aluminum, copper, zinc, and lead industries. (MCW)

  2. [Illegal abortion in Senegal].

    Gomis, E

    1986-09-01

    Because abortion is illegal in Senegal, it is not easy to determine its frequency. Women suffering complications of illegal abortions are often unwilling to aid in their own treatment by divulging the means used to induce the abortion. Clandestine abortions are associated with poor hygienic conditions exposing the woman to risk of infection. Abortion operators are often ignorant of elementary notions of genital anatomy and unskilled in gynecological surgery. Death may result in a few minutes from shock or embolism. The operator is unable to take any action because of the illegal status of the abortion. Secondary complications may appear because of local trauma, infection, or from caustic or toxic agents. Hemorrhage may be external and abundant, originating in the cervix, vagina, or uterine cavity. It may occur within the abdominal cavity if an organ is perforated. In both cases surgical treatment may be required to save the woman's life. An infection or a state of toxicity may result from the abortion, or both may occur simultaneously. Infections of varying degrees of seriousness may be localized in the genital organs (pelviperitonitis), spread throughout the abdomen (general peritonitis), or spread throughout the organism. Pelviperitonitis results from performing abortions under septic conditions and from uterine retention of part of the embryo. Symptoms include abdominal pain, fever, vomiting, and arrest of intestinal transit. Symptoms are often masked by uninformed use of antibiotics, which allows the infection to spread to the other abdominal organs. Generalized peritonitis results from grave lesions of the genital or intestinal tracts produced by traumatizing instruments. In the absence of medical and surgical treatment, the patient's condition rapidly deteriorates and death ensues. Generalized infection may be due to septicemia, tetanus, or hepatonephritis. Hospitalization in a specialized service is required. Thromboembolic complications may also follow

    2009-01-01

    The correlation between bullet hole shapes in metal and projectile impact velocity was examined. A series of shots were fired from an M-16A1 assault rifle of 5.56 mm caliber toward a 1-mm thick metal target. All shots were fired at a perpendicular angle to the metal sheets, and the velocity was measured just before the projectile hit the target. Velocities ranged between 400 and 900 m/sec. From the replica of the shooting hole, a perpendicular plane was created, showing the symmetrical properties of the hole. The best mathematical equation describing the shape of the entrance hole was the exponential function in the form: Y x = A + Be kx. The empirical equation of the hole defined using the regression method is: Y x,V = 8.268/V 0.578018 e(0.584x/V0.005). This equation describes the general shape of shooting holes created by velocities ranging from 440 to 750 m/sec. From this equation, one can estimate the bullet velocity when it hits the target.

  7. Cross sections of deuteron induced nuclear reactions on metal targets

    2005-01-01

    Integral excitation functions for the production of residual nuclides with light charged particles are basic data for different applications. The proton induced nuclear reactions are the most widely used and their cross section data are extensively studied. For practical applications these reactions are followed in importance by deuteron induced reactions. Due to the stripping process the production yield of the deuteron induced reactions is significant. High intensity deuteron beams can be produced relatively simply by accelerators. Deuteron induced reactions play an important role in secondary fast neutron sources, in thin layer activation technology, etc. The search of the literature shows that the cross section database for deuteron induced reactions is very poor (very few data above 15-20 MeV). No systematical study has been performed earlier. In addition the published data (except for a few well measured monitor and medically important reactions) show large discrepancies. To meet the requirements of these applications we performed a systematical experimental study of deuteron induced activation cross sections for different targets up to 50 MeV deuteron energy during the last years. Here we summarize the results for the most widely used technological materials: i.e. for metals. The targets were irradiated with external beams of the cyclotrons of Debrecen, Brussels and Sendai, Residual nuclei were measured by X- and gamma-spectrometry without chemical separation. The investigation includes a few hundred reactions induced on the following 20 target elements: Al, Ti, Fe, Ni, Cu, Zn, Y, Zr, Nb, Mo, Rh, Pd, Ag, Cd, Sn, Te, W, Ir, Pt, Pb. A significant part of the measured data is new. The measured excitation functions were compared with the theory by using the ALICE-IPPE and TALYS codes. For a few elements, isotopic cross sections were measured on highly enriched targets ( 100 Mo, 122,123 Te, 114 Cd) for medical radioisotope production Applications in the field of

    The preparation of microcellular foam in cylindrical gold targets is described. The goal cylinders were fabricated by electroplating gold onto a silicon bronze mandrel and leaching the mandrel with concentrated nitric acid. After several rinsing and cleaning steps, the cylinders were filled with a solution containing trimethylolpropanetriacrylate (TMPTA). Low density, microcellular polymeric foam was prepared by in situ photopolymerization of the TMPTA solution. Foam preparation was extremely sensitive to metal ion contaminants. In particular, copper ions left behind from the leaching process inhibit polymerization and must be removed in order to obtain uniform, non-shrinking foams. A study on the effects of potential contaminants and polymerization inhibitors on TMPTA photopolymerization is presented. In addition, a procedure for the effective leaching and cleaning of gold cylinders is described

    The National Energy Conservation Policy Act of 1978 directs DOE to set targets for increased utilization of energy-saving recovered materials for certain industries. These targets are to be established at levels representing the maximum feasible increase in utilization of recovered materials that can be achieved progressively by January 1, 1987 and is consistent with technical and economic factors. A benefit to be derived from the increased use of recoverable materials is in energy savings, as state in the Act. Therefore, emhasis on different industries in the metals sector has been related to their energy consumption. The ferrous industry (iron and steel, ferrour foundries and ferralloys), as defined here, accounts for approximately 3%, and all others for the remaining 3%. Energy consumed in the lead and zinc segments is less than 1% each. Emphasis is placed on the ferrous scrap users, followed by the aluminum and copper industries. A bibliography with 209 citations is included.

    The influences of lateral target size on hot electron production and electromagnetic pulse emission from laser interaction with metallic targets have been investigated. Particle-in-cell simulations at high laser intensities show that the yield of hot electrons tends to increase with lateral target size, because the larger surface area reduces the electrostatic field on the target, owing to its expansion along the target surface. At lower laser intensities and longer time scales, experimental data characterizing electromagnetic pulse emission as a function of lateral target size also show target-size effects. Charge separation and a larger target tending to have a lower target potential have both been observed. The increase in radiation strength and downshift in radiation frequency with increasing lateral target size can be interpreted using a simple model of the electrical capacity of the target.

La introducción de moneda extranjera, la extracción de metales preciosos y la fabricación de moneda falsa fueron graves problemas que las autoridades trataron de solventar. La moneda provincial de los diferentes reinos se vio gravemente afectada por la falsificación, esto unido a la extracción de moneda legítima provocó momentos de escasez de moneda. AbstractDuring the War of Spanish Succession, there were numerous monetary problems in the peninsular territories. Interruptions in communications with the American Kingdoms gave rise to a shortage of silver, which directly affected currency production. The introduction of foreign currency, the illegal removal of precious metal and counterfeit currency production were serious problems for the authorities. The provincial currency of the different kingdoms was significantly affected by forgery. This, together with the illegal removal of legitimate currency from America, caused periods of shortage of currency.

    Models of a liquid-metal target of an accelerator-controlled system have been experimentally studied at the Nizhny Novgorod State Technical University to develop an optimal design of the flow part of the target. The main explored variants of liquid-metal targets are: Design with a diaphragm (firm-and-impervious plug) mounted on the pipe tap of particle transport from the accelerator cavity to the working cavity of the liquid-metal target. Design without a diaphragm on the pipe tab of particle transport from the accelerator. The study was carried out in a high-temperature liquid-metal test bench under the conditions close to full-scale ones: the temperature of the eutectic lead-bismuth alloy was 260degC - 400degC, the coolant mass flow was 5-80 t/h, and the rarefaction in the gas cavity was 10 5 Pa, the coefficient of geometric similarity equal to 1. The experimental studies of hydrodynamic characteristics of flow parts in the designs of targets under full-scale conditions indicated high efficiency of a target in triggering, operating, and deactivating modes. Research and technology instructions for designs of the flow part of the liquid-metal target, the target design as a whole, and the target circuit of accelerator-controlled systems were formulated as a result of the studies.

    Severe asymmetry of the metal deposits on the trench sidewalls occurs near the wafer edge during low pressure ionized metal physical vapor deposition of Cu seed layer for microprocessor interconnects. To investigate this process and mitigate the asymmetry, an analytical view factor model based on the analogy between metal sputtering and diffuse thermal radiation was constructed to investigate deposition uniformity and symmetry for cylindrical target sputtering in low pressure (below 0.1 Pa) ionized Cu physical vapor deposition. The model predictions indicate that as the distance from the cylindrical target to wafer increases, the metal film thickness becomes more uniform across the wafer and the asymmetry of the metal deposits at the wafer edge increases significantly. These trends are similar to those for planar targets. To minimize the asymmetry, the height of the cylindrical target should be kept at a minimum. For cylindrical targets, the outward-facing sidewall of the trench could receive more direct Cu fluxes than the inward-facing one when the target to wafer distance is short. The predictions also indicate that increasing the diameter of the cylindrical target could significantly reduce the asymmetry in metal deposits at the wafer edge and make the film thickness more uniform across the wafer

    A subcritical transmutation reactor research is in progress for treatment of spent fuel. The subcritical transmutation reactor needs target system to produce high-energy neutrons. In target system, beam window is subject to high thermal field, because it interacts with high energy proton beam. In this study, target was designed based on thermal-hydraulic analysis, and thermal-structural analysis of window was performed. Preliminary design and mechanical analysis of liquid Pb-Bi target and 9Cr-2WVTa window were performed. Target was designed in a way to decrease window temperature. Installation of diffuse plate which has higher porosity in central zone was considered. Temperature and stress of window were analyzed varying minimum window thickness, beam power, and coolant flow rate. Thermal-bending stress was generated in window because of temperature gradient along the thickness of window. Coolant flow rate had insignificant effect on window stresses. It can be concluded that the target and window can be used in transmutation reactor operating condition (1 GeV, 6.78 mA). In this study, only static analysis has been made. But, accelerator beam trip can frequently occur in accelerator operation, so window and target container dynamic stress analysis will be needed. Furthermore, study about corrosion or irradiation characteristics of window will be needed in designing target and window. (authors)

    Most of the world's supply of 99 mTc for medical purposes is currently produced from the decay of 99 Mo derived from the fissioning of high-enriched uranium (HEU). Substitution of low-enriched uranium (LEU) metal foils for the HEU UO 2 used in current target designs will allow equivalent 99 Mo yields with little change in target geometries. Substitution of uranium metal for uranium alloy and aluminide in other target designs will also allow the conversion of HEU to LEU. Several uranium-metal-foil targets have been fabricated at ANL and irradiated to prototypic burnup in the Indonesian RSG-GAS reactor. Postirradiation examination of the initial test indicated that design modifications were required to allow the irradiated foil to be removed for chemical processing. The latest test has shown good irradiation behavior, satisfactory dismantling and foil removal when the U-foil is separated from its containment by metallic, fission-recoil absorbing barriers.

    Full Text Available How to detect the ground motion metal target effectively is an important guarantee for precision strike in the process of Rocket Projectile flight. Accordingly and in view of the millimeter- wave radiation characteristic of the ground motion metal target, a mathematical model was established based on Rocket Projectile about millimeter-wave detection to the ground motion metal target. Through changing various parameters in the process of Rocket Projectile flight, the detection model was studied by simulation. The parameters variation and effective range of millimeter wave radiometer were obtained in the process of rotation and horizontal flight. So a certain theoretical basis was formed for the precision strike to the ground motion metal target.

    Illegal addictive drugs can lead to functional or structural impairment of the central nervous system. This review provides an overview of the structural imaging findings on CT, MR imaging, and conventional angiography related to chronic and acute abuse of the most commonly abused illegal drugs, including cannabis, organic solvents, and amphetamines and opioids and their respective derivatives. Pathomechanisms include excitotoxicity, which may lead to an acute or subacute leukoencephalopathy, and vascular complications, including vasoconstriction, vasculitis, or hypertension, which may lead to intracranial hemorrhage or ischemia. Because clinical findings alone are often nonspecific, and afflicted patients are unlikely to admit to the substance abuse, the neuroradiologist may play an important role in establishing the diagnosis and, thereby, initiating treatment.

    "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." excerpt

    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.

    1982-01-01

    Several 241 Am metal alloys have been investigated for possible use in the Lawrence Livermore National Laboratory Radiochemical Diagnostic Tracer Program. Several properties were desired for an alloy to be useful for tracer program applications. A suitable alloy would have a fairly high density, be ductile, homogeneous and easy to prepare. Alloys investigated have included uranium-americium, aluminium-americium, and cerium-americium. Uranium-americium alloys with the desired properties proved to be difficult to prepare, and work with this alloy was discontinued. Aluminium-americium alloys were much easier to prepare, but the alloy consisted of an aluminium-americium intermetallic compound (AmAl 4 ) in an aluminum matrix. This alloy could be cast and formed into shapes, but the low density of aluminum, and other problems, made the alloy unsuitable for the intended application. Americium metal was found to have a high solid solubility in cerium and alloys prepared from these two elements exhibited all of the properties desired for the tracer program application. Cerium-americium alloys containing up to 34 wt% americium have been prepared using both co-melting and co-reduction techniques. The latter technique involves co-reduction of cerium tetrafluoride and americium tetrafluoride with calcium metal in a sealed reduction vessel. Casting techniques have been developed for preparing up to eight 2.2 cm (0.87 in) diameter disks in a single casting, and cerium-americium metal alloy disks containing from 10 to 25 wt% 241 Am have been prepared using these techniques.

    High power spallation targets are going to be used extensively in future research and technical facilities such as spallation neutron sources, neutrino factories, radioactive beam facilities or accelerator driven systems for the transmutation of long-lived nuclear waste. Within EURISOL-DS, a 4 MW liquid metal spallation target is designed to provide neutrons for a fission target, where neutron rich radionuclides will be produced. For the spallation target, mercury is planned to be used as target material. A large amount of radionuclides ranging from atomic number Z=1 to 81 will be produced in the liquid metal during long term irradiation. It is planned to remove those radionuclides by chemical or physicochemical methods to reduce its radioactivity. For the development of a purification procedure, knowledge about the chemical state of the different elements present in the mixture is required. We present a general concept of applicable separation techniques in a target system and show some results of experiment...

  12. Targeted Structural Optimization with Additive Manufacturing of Metals

    Burt, Adam; Hull, Patrick

    2015-01-01

    The recent advances in additive manufacturing (AM) of metals have now improved the state-of-the-art such that traditionally non-producible parts can be readily produced in a cost-effective way. Because of these advances in manufacturing technology, structural optimization techniques are well positioned to supplement and advance this new technology. The goal of this project is to develop a structural design, analysis, and optimization framework combined with AM to significantly light-weight the interior of metallic structures while maintaining the selected structural properties of the original solid. This is a new state-of-the-art capability to significantly reduce mass, while maintaining the structural integrity of the original design, something that can only be done with AM. In addition, this framework will couple the design, analysis, and fabrication process, meaning that what has been designed directly represents the produced part, thus closing the loop on the design cycle and removing human iteration between design and fabrication. This fundamental concept has applications from light-weighting launch vehicle components to in situ resource fabrication.

  13. Forestry, illegibility and illegality in Omkoi, Northwest Thailand

    Full Text Available Opium poppy cultivation in Thailand fell from 12,112 hectares in 1961 to 281 ha in 2015. One outlier exists: Chiang Mai province’s remote southwestern district, Omkoi. 90% of the district is a national forest reserve where human habitation is illegal. However, an ethnic Karen population has lived there since long before the law that outlawed them was created, unconnected to the state by road, with limited or no access to health, education and other services: they cultivate the majority of Thailand’s known opium poppy, because they have little other choice. They increasingly rely on cash-based markets, their lack of citizenship precludes them from land tenure which might incentivize them to grow alternate crops, and their statelessness precludes them from services and protections. Nor is the Thai state the singular Leviathan that states are often assumed to be; it is a collection of networks with divergent interests, of whom one of the most powerful, the Royal Forestry Department, has purposely made Omkoi’s population illegible to the state, and has consistently blocked the attempts of other state actors to complexify this state space beyond the simplicity of its forest. These factors make short-term, high-yield, high value, imperishable opium the most logical economic choice for poor Karen farmers residing in this “non-state” space.

    "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. excerpt

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.

    2006-01-01

    Severe asymmetry of the metal deposits on the trench sidewalls occurs near the wafer edge during low pressure ionized metal physical vapor deposition of Cu seed layer for microprocessor interconnects. To investigate this process and mitigate the asymmetry, an analytical view factor model based on the analogy between metal sputtering and diffuse thermal radiation was constructed. The model was validated based on the agreement between the model predictions and the reported experimental values for the asymmetric metal deposition at trench sidewalls near the wafer edge for a 200 mm wafer. This model could predict the thickness of the metal deposits across the wafer, the symmetry of the deposits on the trench sidewalls at any wafer location, and the angular distributions of the metal fluxes arriving at any wafer location. The model predictions for the 300 mm wafer indicate that as the target-to-wafer distance is shortened, the deposit thickness increases and the asymmetry decreases, however the overall uniformity decreases. Up to reasonable limits, increasing the target size and the sputtering intensity for the outer target portion significantly improves the uniformity across the wafer and the symmetry on the trench sidewalls near the wafer edge

    The manufacturing and precision monitoring methods of the layers as promising direct and indirect targets for Inertial confinement fusion (ICF) are under study, as well as their application in the experiments. The metal-containing foams with a density that is several times or several orders of magnitude smaller than the full-density material of the same composition are of interest for higher laser light conversion into X-rays and for better energy delivery into the target in direct and indirect interaction schemes. Such targets are developed and provided. We report the interaction of Nd: glass laser with a low-density bismuth and gold targets. The plasma dynamics and X-ray emissions were observed using multiframe optical shadowgraphy and an X-ray streak camera. Enhanced X-ray intensities and festoon plasma flame are observed from the metal low-density layers.

    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

    Optical beam deflection and high-speed photographic methods are employed to investigate the interaction mechanism between a laser-induced bubble and a metal target for underwater laser propulsion. A preliminary theory is proposed to reveal the step increases of the kinetic energy transferred to the target during the process of increasing the incident laser energy. This theory also helps to explain the increasing coupling efficiency with incident laser energy for underwater laser propulsion.

    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.

    The ISOLDE pulsed proton beam peak power amounts to 500 MW during the 2.4 ms proton pulse. The fraction of the proton pulse energy deposited in the target material is at the origin of severe thermal shocks. Quantitative measurement of their effect on the release of radioelements from ISOLDE targets was obtained by comparison of release profiles measured under different proton beam settings. The thermal shock induced in liquids (Pb, Sn, La) lead to mechanical failure of ISOLDE molten metal target vessels. Failure analysis is presented and discussed in the light of the response of mercury samples submitted to the ISOLDE beam and monitored by high-speed optical systems.

Results The levels (mean ± SEM and diversity of metals determined by ICP-MS were highest for red wine samples (30 metals totalling 5620.54 ± 123.86 ppb followed by apple juice (15 metals totalling 1339.87 ± 10.84 ppb and stout (14 metals totalling 464.85 ± 46.74 ppb. The combined THQ values were determined based upon levels of V, Cr, Mn, Ni, Cu, Zn and Pb which gave red wine samples the highest value (5100.96 ± 118.93 ppb followed by apple juice (666.44 ± 7.67 ppb and stout (328.41 ± 42.36 ppb. The THQ values were as follows: apple juice (male 3.11, female 3.87, stout (male 1.84, female 2.19, red wine (male 126.52, female 157.22 and ultra-filtered red wine (male 110.48, female 137.29. Conclusion This study reports relatively high levels of metal ions in red wine, which give a very high THQ value suggesting potential hazardous exposure over a lifetime for those who consume at least 250 mL daily. In addition to the known hazardous metals (e.g. Pb, many metals (e.g. Rb have not had their biological effects systematically investigated and hence the impact of sustained ingestion is not known.

    The polymer-assisted deposition (PAD) method was used to create crack-free homogenous metal oxide films for use as targets in nuclear science applications. Metal oxide films of europium, thulium, and hafnium were prepared as models for actinide oxides. Films produced by a single application of PAD were homogenous and uniform and ranged in thickness from 30 to 320 nm. Reapplication of the PAD method (six times) with a 10% by weight hafnium(IV) solution resulted in an equally homogeneous and uniform film with a total thickness of 600 nm.

    The calculations and analysis of the accumulation of radioactive nuclei and long-lived activity in heavy metal liquid targets were performed. The dominating contributions to the total radioactivity of radionuclides resulting from fission, spallation reactions and radiative capture by target nuclei for various irradiation and cooling times were calculated and analyzed. The most important parts of neutron and proton spectra were determined that give the dominant contributions to the total and partial activity of the targets. The contributions of fission products to the target activity and partial activities of main long-lived fission products were evaluated. The results of the calculations are compared with the data on Energy Amplifier Project. (Author) 12 refs

    1983-01-01

    Fluorocarbon films have been prepared by plasma polymerization of CF 4 using an RF planar magnetron with an aluminium target. More than one order of magnitude higher deposition rate has been achieved in comparison with an r.f. diode system operated under similar conditions of monomer pressure and flow rate and power input. A glow discharge in a CF 4 [25%]-argon[75%] mixture was used to incorporate aluminium from a target electrode into the polymer films. The foregoing mixture and another based on CF 4 [87%]-argon[13%] were used in the RF discharge with a copper target. Some experiments with a gold target and pure CF 4 as the inlet gas were also made. The film structure was examined by SEM and TEM and characteristic micrographs are presented here. The composition of the films was estimated from an EAS study. The sheet resistivity of the metal/polymer film complexes was determined. (orig.)

    About six times more low enriched uranium (LEU) metal is needed to produce the same quantity of 99 Mo as from a high enriched uranium (HEU) oxide target, under similar conditions of neutron irradiation. In view of this, the post-irradiation processing procedures of the LEU target are likely to be different from the Cintichem process procedures now in use for the HEU target. The authors have begun a systematic study to develop modified procedures for LEU target dissolution and 99 Mo separation. The dissolution studies include determination of the dissolution rate, chemical state of uranium in the solution, and the heat evolved in the dissolution reaction. From these results the authors conclude that a mixture of nitric and sulfuric acid is a suitable dissolver solution, albeit at higher concentration of nitric acid than in use for the HEU targets. Also, the dissolver vessel now in use for HEU targets is inadequate for the LEU target, since higher temperature and higher pressure will be encountered in the dissolution of LEU targets. The desire is to keep the modifications to the Cintichem process to a minimum, so that the switch from HEU to LEU can be achieved easily

    Biopharmaceuticals have established themselves as highly efficient medicines, and are still one of the fastest growing parts of the health-product industry. Unfortunately, the introduction of these promising new drugs went hand in hand with the creation of a black market for illegal and counterfeit biotechnology drugs. Particularly popular are the lyophilised peptides with a molecular weight of less than 5kDa. Most of them are meant for subcutaneous injection and are easily accessible via the internet. In recent years, different methods based on reversed phase liquid chromatography have been developed to detect and quantify these peptides. The emerging of more polar peptides however requires the introduction of other separation techniques. Therefore, we set out to develop and validate an analytical method based on hydrophilic interaction liquid chromatography (HILIC) to identify and quantify the most frequently encountered illegal peptides on the European market. For this objective, five different HILIC columns were selected and screened for their chromatographic performance. Among those columns, the ZIC HILIC column showed the best performance under the tested screening conditions in terms of resolution and symmetry factor for the targeted peptide set. Hence, the operational conditions were further optimised for the identification of illegal preparations via mass spectrometry (MS) and quantification via UV. Validation was performed via accuracy profiles based on the ISO 17025 guideline. The obtained validated HILIC-method allows for the detection and quantification of the most frequently encountered illegal peptides on the internet in a total run time of 35min including post gradient equilibration and online cleaning step. Combined with a previously developed RPLC-method, the ZIC HILIC system allows for the detection and quantification of a wide spectrum of illicit peptide drugs available on the internet. Furthermore, the developed method could also be envisaged

    Full Text Available Abstract Background Metal ions such as iron and copper are among the key nutrients that must be provided by dietary sources. Numerous foodstuffs have been evaluated for their contributions to the recommended daily allowance both to guide for satisfactory intake and also to prevent over exposure. In the case of heavy metal ions, the focus is often on exposure to potentially toxic levels of ions such as lead and mercury. The aim of this study is to determine target hazard quotients (THQ from literature reports giving empirical levels of metal ions in table wines using the reference upper safe limit value. Contributions to the THQ value were calculated for seven metal ions along with total values for each wine. Results The THQ values were determined as ranges from previously reported ranges of metal ion concentrations and were frequently concerningly high. Apart from the wines selected from Italy, Brazil and Argentina, all other wines exhibited THQ values significantly greater than one indicating levels of risk. The levels of vanadium, copper and manganese had the highest impact on THQ measures. Typical potential maximum THQ values ranged from 50 to 200 with Hungarian and Slovakian wines reaching 300. THQ values for a sample of red and white wines were high for both having values ranging from 30 to 80 for females based on a 250 mL glass per day. Conclusion The THQ values calculated are concerning in that they are mainly above the safe level of THQ

  17. Asymmetric partitioning of metals among cluster anions and cations generated via laser ablation of mixed aluminum/Group 6 transition metal targets.

    While high-power laser ablation of metal alloys indiscriminately produces gas-phase atomic ions in proportion to the abundance of the various metals in the alloy, gas-phase ions produced by moderate-power laser ablation sources coupled with molecular beams are formed by more complicated mechanisms. A mass spectrometric study that directly compares the mass distributions of cluster anions and cations generated from laser ablation of pure aluminum, an aluminum/molybdenum mixed target, and an aluminum/tungsten mixed target is detailed. Mass spectra of anionic species generated from the mixed targets showed that both tungsten and molybdenum were in higher abundance in the negatively charged species than in the target material. Mass spectra of the cationic species showed primarily Al(+) and aluminum oxide and hydroxide cluster cations. No molybdenum- or tungsten-containing cluster cations were definitively assigned. The asymmetric distribution of aluminum and Group 6 transition metals in cation and anion cluster composition is attributed to the low ionization energy of atomic aluminum and aluminum suboxide clusters. In addition, the propensity of both molybdenum and tungsten to form metal oxide cluster anions under the same conditions that favor metallic aluminum cluster anions is attributed to differences in the optical properties of the surface oxide that is present in the metal powders used to prepare the ablation targets. Mechanisms of mixed metal oxide clusters are considered.

    The first advanced design of accelerator-driven systems (ADS) is currently being built in SCK-CEN (Mol, Belgium): MYRRHA (Multi-purpose hybrid research reactor for high-tech applications). The experiment investigates the free surface design of the MYRRHA target. The free surface lead-bismuth eutectic (LBE) liquid metal experiment is a full-scale model of the concentric MYRRHA target. The design of the target is combined with CFD simulations using a volume of fluid method accounting for mass transfer across the free surface. The model used has been validated with water experimental results. The design of the target enables a high fluid velocity and a stable surface at the beam entry. In the current work, we present numerical results of Star- CD simulations employing a high-resolution interface-capturing scheme in conjunction with the cavitation model for the nominal operation conditions. Thermal hydraulic of the target is considered for the nominal flow rate and nominal heat load. Results show that the target has a very stable free surface configuration for the considered flow rate and heat load

    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.

    Internationally, illegal drug use remains a major public health problem. In response, many countries have begun to shift their illegal drug policies away from enforcement and towards public health objectives. Recently, both the Global Commission on Drug Policy and the Supreme Court of Canada have endorsed this change in direction, supporting empirically sound illegal drug policies that reduce criminalization and stigmatization of drug users and bolster treatment and harm reduction efforts. Until recently, Canada was a participant in this growing movement towards rational drug policy. Unfortunately, in recent years, policy changes have made Canada one of the few remaining advocates of a "war-on-drugs" approach. Indeed, the current government has implemented a number of new illegal drug policies that contradict well-established scientific evidence from public health, criminology and other fields. As such, their approach is expected to do little to reduce the harms associated with substance use in Canada. The authors call on the current government to heed the recommendations of the Global Commission's report and learn from the many countries that are innovating in illegal drug policy by prioritizing evidence, human rights and public health.

    In this paper melt layer erosion of metal targets under pulsed high-heat loads is studied. Experiments with steel, copper, aluminum and titanium samples were carried out in two plasma accelerator devices with different time durations of the heat load. The surfaces of the resolidified melt layers show a considerable roughness with microcraters and ridge like relief on the surface. For each material the mass loss was determined. Melt layer erosion by melt motion was clearly identified. However it is masked by boiling, bubble expansion and bubble collapse and by formation of a Kelvin-Helmholtz instability. The experimental results can be used for validation of numerical codes which model melt layer erosion of metallic armour materials in off-normal events, in tokamaks.

    "This paper extends the work of Ethier on illegal immigration by examining the optimal level of enforcement for the labor-importing country in a two-country model and by considering the effects of allowing capital mobility. We derive a formula for the optimal level of enforcement against firms that hire illegal workers, and show that the presence of enforcement costs makes the policy less efficient than a wage tax. With capital mobility, foreign workers gain from an increase in enforcement in the home country because capital is driven out of the home country." excerpt

    Body packers are persons who smuggle illegal drugs by swallowing condoms or plastic cylinders containing such substances. Body stuffers are drug dealers or drug abusers who swallow illegal drugs in an effort to conceal evidence during an arrest or in fear of being arrested. We report four cases and discuss management. Asymptomatic body packers may be managed conservatively with laxatives and water-soluble contrast medium. This method allows an accurate follow-up with abdominal radiography. If patients develop abdominal pain or signs and symptoms of intoxication, surgical intervention should be considered. Both types of patients should be monitored carefully.

    2008-01-01

    Full Text Available Abstract Prohibition of illegal drugs is a failed social policy and new models of regulation of these substances are needed. This paper explores a proposal for a post-prohibition, public health based model for the regulation of the most problematic drugs, the smokable and injectable stimulants. The literature on stimulant maintenance is explored. Seven foundational principles are suggested that could support this regulatory model of drug control that would reduce both health and social problems related to illegal stimulants. Some details of this model are examined and the paper concludes that drug policies need to be subject to research and based on evidence.

    We have investigated the s-wave elastic scattering of antihydrogen atoms off atomic alkali-metal targets (Li, Na, K, and Rb) at thermal energies (10 -16 -10 -4 a.u.) using an atomic orbital expansion technique. The elastic cross sections of these systems at thermal energies are found to be very high compared to H-H and H-He systems. The theoretical models employed in this study are so chosen to consider long-range forces dynamically in the calculation. The mechanism of cooling suggests that Li may be considered to be a good candidate as a buffer gas for enhanced cooling of antihydrogen atoms to ultracold temperature

    Highlights: • Experimental study of free surface for lead bismuth eutectic target. • Numerical investigation of free surface of a liquid metal target. • Advanced free surface modelling. - Abstract: Accelerator Driven Systems (ADS) are extensively investigated for the transmutation of high-level nuclear waste within many worldwide research programs. The first advanced design of an ADS system is currently developed in SCK• CEN, Mol, Belgium: the Multi-purpose hYbrid Research Reactor for High-tech Applications (MYRRHA). Many European research programs support the design of MYRRHA. In the framework of the Euratom project ‘Thermal Hydraulics of Innovative nuclear Systems (THINS)’ a liquid-metal free-surface experiment is performed at the Karlsruhe Liquid Metal Laboratory (KALLA) of Karlsruhe Institute of Technology (KIT). The experiment investigates a full-scale model of the concentric free-surface spallation target of MYRRHA using Lead Bismuth Eutectic (LBE) as coolant. In parallel, numerical free surface models are developed and tested which are reviewed in the article. A volume-of-fluid method, a moving mesh model, a free surface model combining the Level-Set method with Large-Eddy Simulation model and a smoothed-particle hydrodynamics approach are investigated. Verification of the tested models is based on the experimental results obtained within the THINS project and on previous water experiments performed at the University Catholic de Louvain (UCL) within the Euratom project ‘EUROpean Research Programme for the TRANSmutation of High Level Nuclear Waste in Accelerator Driven System (EUROTRANS)’. The design of the target enables a high fluid velocity and a stable surface at the beam entry. The purpose of this paper is to present an overview of both experimental and numerical results obtained for free surface target characterization.

    Implantation of 85 Kr in a growing sputtered metal deposit has been studied for the containment of 85 Kr recovered from the reprocessing of spent nuclear fuel. PNL, as part of DOE's research program for 85 Kr storage, has developed krypton trapping storage devices (KTSDs) in a range of sizes for ''cold'' and radioactive testing. The KTSD is a stainless steel canister that contains a sputtering target for depositing an amorphous rare-earth transition metal on the inner wall and simultaneously implanting low-energy krypton ions in the growing deposit. This report covers the design requirements for the target power supply and the description, testing and evaluation of three basic designs. The designs chosen for evaluation were: (1) a standard commercial power supply with an external PNL-designed current interrupter, (2) a commercially manufactured power supply with an integral series-type interrupter, and (3) a commercially manufactured power supply with an integral shunt-type interrupter. The units were compared on the basis of performance, reliability, and life-cycle cost. 8 refs., 9 figs., 2 tabs

  16. 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.

    Full Text Available Retracted articleThe present article examines the theoretical and methodological issues in the study of illegal migration and international cooperation aimed at preventing illegal migration. When analyzing the issues of illegal immigration, the theoretical and methodological justification becomes of a special importance. At present, the task of systematization and standardization of terminology with respect to illegal migration analysis seems to be especially relevant, without which it is impossible to start formalizing data on the global scale. The present study provides us with the analysis of the phenomenon of illegal immigration, outlines methodological obstacles in assessing the scale of illegal immigration as well as its negative consequences. Author suggests a model for measuring illegal immigration and ways to improve state regulations of illegal migration. 

  19. Illegal births and legal abortions – the case of China

    2005-08-01

    Full Text Available Abstract Background China has a national policy regulating the number of children that a woman is allowed to have. The central concept at the individual level application is "illegal pregnancy". The purpose of this article is to describe and problematicize the concept of illegal pregnancy and its use in practice. Methods Original texts and previous published and unpublished reports and statistics were used. Results By 1979 the Chinese population policy was clearly a policy of controlling population growth. For a pregnancy to be legal, it has to be defined as such according to the family-level eligibility rules, and in some places it has to be within the local quota. Enforcement of the policy has been pursued via the State Family Planning (FP Commission and the Communist Party (CP, both of which have a functioning vertical structure down to the lowest administrative units. There are various incentives and disincentives for families to follow the policy. An extensive system has been created to keep the contraceptive use and pregnancy status of all married women at reproductive age under constant surveillance. In the early 1990s FP and CP officials were made personally responsible for meeting population targets. Since 1979, abortion has been available on request, and the ratio of legal abortions to birth increased in the 1980s and declined in the 1990s. Similar to what happens in other Asian countries with low fertility rates and higher esteem for boys, both national- and local-level data show that an unnaturally greater number of boys than girls are registered as having been born. Conclusion Defining a pregnancy as "illegal" and carrying out the surveillance of individual women are phenomena unique in China, but this does not apply to other features of the policy. The moral judgment concerning the policy depends on the basic question of whether reproduction should be considered as an individual or social decision.

  3. EURISOL Multi-MW Target: Investigation of the hydrodynamics of liquid metal (Hg) jet

    CERN Document Server

    Freibergs, J

    In order to develop a windowless target it is necessary to investigate the hydrodynamics of liquid metal (Hg) jet. On the basis of the schematic layout of a high-power target module presented in Ref. [2], and the parameters of the windowless target (speed of the mercury jet up to 30 m/s, diameter of jet 10-20 mm and length of jet about 1 m), a first estimation of the parameters of the main components of a Hg-loop has been obtained by the Institute of Physics, University of Latvia. A preliminary engineering design of a functional Hg-loop to be constructed soon is also proposed. A simplified water stand has been developed with the ability of testing different Hg-nozzle configurations. The tests carried out showed that the kinetic energy of the jet is so high that the coaxial water flow at contact point is transformed into small bubbles (spray). The characteristics of the jet were shown to depend on the pressure of the stand.

    This reports an experimental study on flow characteristics of a lithium target flow of International Fusion Materials Irradiation Facility (IFMIF). Surface shapes of the target were tried to measure by pattern projection method that is a three dimensional image measurement method. Irregularity of the surface shape caused by surface wakes was successfully measured by the method. IFMIF liquid lithium target is formed a flat plane jet of 25 mm in depth and 260 mm in width, and flows in a flow velocity range of 10 to 20 m/s. Aim of this study is to develop measurement techniques for monitoring of the target when IFMIF is in operation. The lithium target flow is high speed jet and the temperature high is more than 500 K. Also, light is not transmitted into liquid metal lithium. Therefore, almost of all flow measurement techniques developed for water are not used for lithium flow. In this study, pattern projection method was employed to measure the surface irregularity of the target. In the method, stripe patterns are projected onto the flow surface. The projected patterns are deformed according the surface shape. Three-dimensional surface shape is measured by analyzing the deformed patterns recorded using a CCD camera. The method uses the property that lithium dose not transmit visible lights. The experiments were carried out using a lithium loop at Osaka University. In this facility, lithium plane jet of 10 mm in depth and 70 mm width is obtained in the velocity range of less than 15 m/s using a two contractions nozzle. The pattern projection method was used to measure the amplitude of surface irregularity caused by surface wakes. The surface wakes were generated from small damaged at the nozzle edge caused by erosion, and those were successfully measured by the method. The measurement results showed the amplitude of the surface wakes were approximately equal to a size of damage of a nozzle. The amplitude was decreasing with distance to down stream and with decreasing

    A cluster of 22 imported malaria cases, 21 caused by Plasmodium falciparum, was observed among illegal Chinese immigrants in northern Italy in the summer of 2000. The rate of severe disease was high because the patients were not immune and they sought health-care services late in their illness because of their clandestine status. Recognition of the outbreak was delayed because no regional alert system among infectious diseases hospitals was in place.

    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.

    Immigration policies and their management in a country like Canada have long been an interesting and instructive study for other countries. 1) With borders naturally protected by great distance from almost all migrant routes; 2) with a long, undefended border with the US and a further 3000 kilometers to its border on the south; 3) with a parliamentary system capable of comparatively rapid legislative and administrative responses to problems; and 4) with a relatively small legal, and even smaller illegal, population Canada had historically "experimented" with novel, often quite creative, immigration policies and programs to both encourage and control the increases in its population. This paper summarizes what Canada did and is doing in response to am important item of public policy--the entry and presence of illegal migrants. Canada has experimented with 1) discretionary amnesty for long-term illegals with a capacity to be successfully integrated into Canadian life, 2) tighter border controls with the extended use of the visitor's visa, and 3) employer sanctions. To address the problem more substantively, however, requires detailed study and significant change, including legislative change.

  18. Reconstruction of Colloidal Spheres by Targeted Etching: A Generalized Self-Template Route to Porous Amphoteric Metal Oxide Hollow Spheres.

    Pan, Jia Hong; Bai, Yuqing; Wang, Qing

    2015-04-21

    Despite the significant progress in developing various synthetic strategies for metal oxide hollow spheres (h-MO), the so-far explored materials are mostly chemically inert metal oxides. Very few attempts have been made for amphoteric metal oxides such as Al2O3 and ZnO due to the difficulties in the control of the dissolution and recrystallization process. Herein, a facile self-template route to the synthesis of amphoteric h-MO with tunable size and shell thickness is developed by targeted etching via an acid-base reaction. With the protection of polyvinylpyrrolidone (PVP) on the surface, the interior of metal oxide solid colloidal spheres (c-MOs) that possess radially divergent structures could be selectively etched with acid/alkali as an etchant, forming h-MO of Al2O3 and ZnO. Our results also show that a wide variety of metal oxide colloidal spheres can be potential self-templates for targeted etching, which paves the way for developing a generalized strategy for the synthesis of various metal oxide hollow spheres.

    Two liquid metals (LM), Li and LiSn (20:80 at), presently considered as alternative materials for the divertor target of a fusion reactor, have been exposed to the plasma in a capillary porous system (CPS) arrangement in TJ-II. A negligible perturbation of the plasma has been recorded in both cases, even when stellarator plasmas are particularly sensitive to high Z elements due to the tendency to central impurity accumulation. The surface temperature of the LM CPS samples (made of a tungsten mesh impregnated in SnLi or Li) has been measured during the plasma pulse with ms resolution by pyrometry and the thermal balance during heating and cooling has been used to obtain the thermal parameters of the SnLi and Li CPS arrangements. Temperatures as high as 1150 K during TJ-II plasma exposure were observed for the LiSn solid case. Strong changes in the thermal conductivity of the alloy were recorded in the cooling phase at temperatures close to the nominal melting point. The deduced values for the thermal conductivity of the LiSn alloy/CPS sample were significantly lower than those predicted from their individual components.

    Full Text Available Abstract This study investigates the nature and behaviour of illegal gamblers in Hong Kong. A face-to-face street survey of 512 gamblers was conducted in Hong Kong between September and December 2015 with supplementary convenience sampling allowing for analysis of a total sample of 103 illegal gamblers. 56% of illegal gamblers recorded results consistent with this study’s definition of ‘excessive gambling’ [i.e. moderate risk and problem gamblers under the Problem Gambling Severity Index (PGSI]. 81% of surveyed illegal gamblers were male, 77% were aged between 30 and 49 and 67% were in blue collar occupations. Illegal gamblers bet more frequently on both legal and illegal games than their legal counterparts and spent more when they did bet. While this research did not indicate the direction of causality between illegal and excessive gambling, international work (de Bruin et al. in verslingerd aan meer dan een spel: Een onderzoek naar de aard en omvang van kansspelproblematiek in Nederland, WODC/CVO, Utrecht, http://www.lexandgaming.eu/nl/wp-content/uploads/2015/01/Verslingerd-aan-meer-dan-een-spel.pdf , 2005; Binde in What are the most harmful forms of gambling? Analysing problem gambling prevalence surveys, http://www.utbildning.gu.se/digitalAssets/1327/1327132_cefos-wp12.pdf , 2011 suggests that excessive gamblers are drawn to illegal gambling. Reform could allow excessive gambling by illegal gamblers to be better addressed and initial work suggests some financial benefits to Hong Kong.

    Novel N3-substituted 9,10-Phenanthrenequinone thiosemicarbazones and their copper, nickel and palladium complexes are structurally characterized and reported along with the single crystal X-ray structures of three ligands and one nickel complex. All compounds were evaluated for their antiproliferative potential against Triple Negative Breast Cancer (TNBC) cells which have poor prognosis and no effective drugs to treat with. All compounds exhibited antiproliferative activity against these cells. Among the metal complexes evaluated, redox active copper complexes were found to be more potent. The possible mechanism for such enhanced activity can be attributed to the generation of oxidative stress, which was amenable for targeting through metal complexation.

    Highlights: • Water model of liquid metal target for validation of CFD models was built. • PIV measurements showed flow features in the region near beam entrance window. • The zones with high turbulence kinetic energy were distinguished. • Reasonable agreement between modeling and PIV data was obtained. - Abstract: After the first world liquid metal target has been successfully operated at the SINQ facility at the Paul Scherrer Institut (PSI) for 6 months. The idea of having a reliable target with a bypass flow for cooling the beam entrance window, but with the bypass flow not driven by a separate pump, was examined within the project called LIMETS (Liquid Metal Target for SINQ). In designing of liquid metal targets, turbulence modelling is of high importance due to lack in methods for measuring the spatial distribution of flow and turbulence characteristics. In this study, validation of different turbulence models were performed in water model with hemispherical geometry using particle image velocimetry (PIV) technique. Two components of water flow velocity in plexiglas container with inner radius of 88 mm were measured in different cross sections, with the velocities varying from 1 to 10 m/s. Numerical calculations using large eddy simulation (LES) approach and Reynolds averaged Navier–Stokes (RANS) models were carried out to validate their applicability and study performance issues. Mean velocity and turbulence kinetic energy data were used for comparison of PIV and calculation results. Reasonable agreement was obtained for mean velocity data, with some discrepancies due to the limited length of the inlet tube. However, several discrepancies in turbulence characteristics were found in numerical results, especially in RANS model calculations

    In the present paper, the penetration experiments of tungsten-fiber/metallic-glass matrix composite material bullets into 45# steel targets are conducted by employing H25 artillery. In which, an experimental technique of sub-caliber penetration is constructed. The quasi static and dynamic behaviours of tungsten-fiber/metallic-glass matrix composite material are also experimental investigated. The self-sharpening phenomenon of composite material is observed. Integrated with metallographic analysis, the failure modes of tungsten-fiber/metallic-glass matrix composite material are identified systemically and compared with the quasi-static and dynamic material tests. It includes four failure modes, i.e., shear fracture of tungsten fiber, brittle fracture of tungsten fiber and shear fracture of metallic glass matrix as well as melting of tungsten fiber and metallic glass matrix. Comparatively, three failure mechanisms of tungsten fiber in the bullet nose are also identified, i.e., shear fracture, splitting fracture and bending or/and buckling. Finally, the mechanism of self-sharpening behaviour of tungsten-fiber/metallic-glass matrix composite material is discussed.

    Full Text Available In the present paper, the penetration experiments of tungsten-fiber/metallic-glass matrix composite material bullets into 45# steel targets are conducted by employing H25 artillery. In which, an experimental technique of sub-caliber penetration is constructed. The quasi static and dynamic behaviours of tungsten-fiber/metallic-glass matrix composite material are also experimental investigated. The self-sharpening phenomenon of composite material is observed. Integrated with metallographic analysis, the failure modes of tungsten-fiber/metallic-glass matrix composite material are identified systemically and compared with the quasi-static and dynamic material tests. It includes four failure modes, i.e., shear fracture of tungsten fiber, brittle fracture of tungsten fiber and shear fracture of metallic glass matrix as well as melting of tungsten fiber and metallic glass matrix. Comparatively, three failure mechanisms of tungsten fiber in the bullet nose are also identified, i.e., shear fracture, splitting fracture and bending or/and buckling. Finally, the mechanism of self-sharpening behaviour of tungsten-fiber/metallic-glass matrix composite material is discussed.

    This technical note summarises the design calculations performed within Task #2 of the European Isotope Separation On-Line Radioactive Ion Beam Facility Design Study (EURISOL-DS) [1]. A preliminary study was carried out in order to determine the optimum value of relevant parameters in the target design. Different scenarios were simulated using the Monte Carlo code FLUKA [2]. Namely, sensitivity studies were performed to assess the impact of the projectile particle energy on the neutronics and energy deposition in the spallation target. The optimal target dimensions were also studied for every case as well as the proper target material for the liquid metal proton-to-neutron converter, since mercury and lead-bismuth eutectic are reasonable options. The effect of the beam width on the power densities was also evaluated, taking into account the geometrical limitations of the facility. Finally, a comparison between protons and deuterons as primary particles was performed, acknowledging the limitations of using FLU...

    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. PMID:25136107

    Illegal trade threatens the survival of many wild species, and molecular forensics can shed light on various questions raised during the investigation of cases of illegal trade. Among these questions is the identity of the species involved. Here we report a case of a man who was caught in a Brazilian airport trying to travel with 58 avian eggs. He claimed they were quail eggs, but authorities suspected they were from parrots. The embryos never hatched and it was not possible to identify them based on morphology. As 29% of parrot species are endangered, the identity of the species involved was important to establish a stronger criminal case. Thus, we identified the embryos' species based on the analyses of mitochondrial DNA sequences (cytochrome c oxidase subunit I gene [COI] and 16S ribosomal DNA). Embryonic COI sequences were compared with those deposited in BOLD (The Barcode of Life Data System) while their 16S sequences were compared with GenBank sequences. Clustering analysis based on neighbor-joining was also performed using parrot COI and 16S sequences deposited in BOLD and GenBank. The results, based on both genes, indicated that 57 embryos were parrots (Alipiopsitta xanthops, Ara ararauna, and the [Amazona aestiva/A. ochrocephala] complex), and 1 was an owl. This kind of data can help criminal investigations and to design species-specific anti-poaching strategies, and demonstrate how DNA sequence analysis in the identification of bird species is a powerful conservation tool. © The American Genetic Association 2015.

    2013-01-01

    The use of illegal drugs generates a wide range of social harms depending on various ways, according to the policy definition of the problem. The challenge is the way to model the impact of illegal drugs use during a long time period considering the factors that affects the process. Based on these models, estimation could be measured and prediction could be achieved. The illegal drugs use might affect the economic and social structure of the public system leading to direct and effective decisions to overcome the problematic. For that reason, calculation of social cost related to the use of illegal could be introduced over time (t) as a proposed social measure to define the variability of social indicator on society. In this work, a theoretical approach for the calculation of social cost of illegal drugs is proposed and models over time are defined.

    Nowadays development of construction in Malaysia has been effect to the increasing of construction waste. Additionally, the production of construction waste from construction projects has given negative impact to the environment especially in illegal dumping activities. The increasing number of illegal dumping activities from construction projects in Malaysia gives a sign that Malaysian construction waste management needs to be concerned. To date, a comprehensive criterion for construction waste management, particularly for a construction project in developing countries is still not clearly defined. Therefore, construction waste management in Malaysia needs further research. The objectives of this paper are to explore illegal dumping activities, and discuss the contributory factors of illegal dumping activities. Hence, this research conducted an interview with expertise in the area of construction waste management in order to scrutinise illegal dumping activities in Malaysia. The data from semistructured interviews were analysed by content analysis. Findings from this research will help to find out the strategies to reduce the illegal dumping activities. The final result also expected to increase the awareness and better solution for reducing illegal dumping activities in construction projects among construction players.

    Developments of the neutron scattering facility is carried out under the high-intensity proton accelerator project promoted by JAERI and KEK. To estimate the structural integrity of the heavy liquid-metal (mercury) target used as a spallation neutron source in a MW-class neutron scattering facility, static and dynamic stress (including pressure wave in mercury) behaviors due to the incident of 1MW-pulsed proton beam (Maximum heat density is 461W/cc) were analyzed. In the analyses, two type target containers with semi-cylindrical type and flat-type beam windows were used as analytical models. As a result, it is confirmed that the stress generated by the pressure wave becomes the largest at the center of the beam window, and the flat-type beam window is more advantageous from the structural viewpoint than the semi-cylindrical type beam window. It has been understood that the stress generated in the beam window by the pressure wave can be treated as the secondary stress. Then, it has been understood that the stress and the stress range generated in the target window were bellow the allowable stress level defined by the standard of JIS on the maximum stress and fatigue strength. It has been experimentally confirmed that a cavitation was generated by generating the negative pressure in mercury near the target beam window and a collapse of cavitation damaged to the target container material, as pits. Then, the fracture mechanical analyses were carried out on the pit and a crack on pit tip. Consequently, it was clarified that the crack would not propagate because the inner surface of the beam window was become the compressive stress field due to the steady state thermal stress. Moreover, the evaluation technique of the cavitation which would be needed in the future was summarized. (author)

  7. ANALYSIS OF REMEDIATION PROCESS OF THE GROUDWATER COTAMINATION IN AN ILLEGAL DUMPING SITE

    Nishida, Norikazu; Furuichi, Toru; Ishii, Kazuei

    Among on-site remediation technologies applied to illegal dumping sites, a technology to remedy contaminated groundwater without removal of the dumped waste is expected to provide a great opportunity to fulfill a societal need due to its economic advantage compared to removal of all waste. However heterogeneously-distributed waste makes the remedial process difficult. In this study, an in situflushing technology was applied to an illegal dumping site in Kuwana city, Mie, in order to remedy groundwater contaminated with several volatile organic compounds (VOCs) within five years. The key to successfully achieve the target was to conduct a series of advanced remediation processes; introducing a new indicator by which multiple VOCs can be estimated integratelly, monitoring the progress of remediation with a contour map of VOC concentration as well as the weighted averages of the concentration derived from the indicator, pinpointing residual contaminants area, reexamining the plan, and taking additional steps that promote further remediation.

    2013-01-01

    Because of the continuing use of nuclear fuel sources and heightened threats of nuclear weapon use, the amount of produced and released radionuclides is increasing daily, as is the risk of larger human exposure to fission product actinides. A rodent model was used to follow the in vivo distribution of representative actinides, administered as free metal ions or complexed with chelating agents including diethylenetriamine pentaacetic acid (DTPA) and the hydroxypyridinonate ligands 3,4,3-LI(1,2-HOPO) and 5-LIO(Me-3,2-HOPO). Different metabolic pathways for the different metal ions were evidenced, resulting in intricate ligand- and metal-dependent decorporation mechanisms. While the three studied chelators are known for their unrivaled actinide decorporation efficiency, the corresponding metal complexes may undergo in vivo decomposition and release metal ions in various biological pools. This study sets the basis to further explore the metabolism and in vivo coordination properties of internalized actinides for the future development of viable therapeutic chelating agents.

    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." excerpt

    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. excerpt

    We developed a new inhalation exposure method to evaluate effects of synthetic cannabimimetics that are being distributed as new, unregulated drugs in the Tokyo area. We selected the commercial product "SOUTOU" containing AB-CHMINACA and 5F-AMB as the test drug and dried marshmallow (Althaea officinalis) leaves as the negative control. A half cigarette packed with dried marshmallow leaves or SOUTOU was ignited, then mainstream smoke from each was delivered to five mice in an exposure box. After the cigarettes were fully consumed, neurobehavioral observations and a catalepsy test were performed at 15, 30 and 60 min after exposure. The effluent air from the exposure box was poured into impingers containing acetonitrile (first impinger) and dimethyl sulfoxide (second impinger). The resulting solutions were analyzed to assess decomposition of the synthetic cannabimimetics. Mice exposed to SOUTOU smoke showed many excitement behaviors and some suppressive behaviors at 15, 30 and 60 min. These clearly included cannabimimetic specific pharmacological actions. Negative control mice also showed some suppressive behaviors at 15 min but these were attenuated at later times, nearly disappearing at 60 min. In addition, the behavioral effects observed in controls were less pronounced than those in SOUTOU exposed mice. The inhalation exposure method developed in our study would be effective for determining cannabinoid specific pharmacological effects of illegal drugs, as well as for assessing the presence of active compound(s) by comparing the test substance with a negative control.

    Novel N(3)-substituted 9,10-Phenanthrenequinone thiosemicarbazones and their copper, nickel and palladium complexes are structurally characterized and reported along with the single crystal X-ray structures of three ligands and one nickel complex. All compounds were evaluated for their antiproliferative potential against Triple Negative Breast Cancer (TNBC) cells which have poor prognosis and no effective drugs to treat with. All compounds exhibited antiproliferative activity against these cells. Among the metal complexes evaluated, redox active copper complexes were found to be more potent. The possible mechanism for such enhanced activity can be attributed to the generation of oxidative stress, which was amenable for targeting through metal complexation. Copyright © 2013 Elsevier B.V.

  14. Identifying Demand Responses to Illegal Drug Supply Interdictions.

    Cunningham, Scott; Finlay, Keith

    2016-10-01

    Successful supply-side interdictions into illegal drug markets are predicated on the responsiveness of drug prices to enforcement and the price elasticity of demand for addictive drugs. We present causal estimates that targeted interventions aimed at methamphetamine input markets ('precursor control') can temporarily increase retail street prices, but methamphetamine consumption is weakly responsive to higher drug prices. After the supply interventions, purity-adjusted prices increased then quickly returned to pre-treatment levels within 6-12 months, demonstrating the short-term effects of precursor control. The price elasticity of methamphetamine demand is -0.13 to -0.21 for self-admitted drug treatment admissions and between -0.24 and -0.28 for hospital inpatient admissions. We find some evidence of a positive cross-price effect for cocaine, but we do not find robust evidence that increases in methamphetamine prices increased heroin, alcohol, or marijuana drug use. This study can inform policy discussions regarding other synthesized drugs, including illicit use of pharmaceuticals. Copyright © 2015 John Wiley & Sons, Ltd.

    2004-01-01

    This case series presents our experience with burns sustained while manufacturing illegal drugs. All adult burn admissions in an 18-month period were retrospectively reviewed. All patients suspected of sustaining burns from illegal drug manufacture were contacted. Information regarding the burn mechanism was sought. Nine of the 64 adult burn admissions were caused by explosions during the manufacture of cannabis oil. Young males with hand and face burns were heavily represented. First-aid treatment was often ignored in favor of hiding incriminating evidence. Only two patients gave honest admission histories. Illegal drug manufacture is becoming more common as synthetic drugs become more consumer desirable. Burns sustained may be thermal and/or chemical. Dishonest patient histories negatively influence burn management. A high level of suspicion is required for diagnosing and treating burns from illegal drug manufacture. Public education is unlikely to be effective as the financial rewards outweigh the perceived risks.

  17. Illegal markets, human trade and transnational organised crime

    Directory of Open Access Journals (Sweden)

    Nikolić-Ristanović Vesna Ž.

    2003-01-01

    Full Text Available In this paper the author explores, focusing largely on the example of the Balkans, the connection between the expansion of neoliberal market economy and war, and related to it the growth of illegal markets and the shadow economy, on one hand, and the victimisation by human trafficking, on the other. By locating human trade within expanding local and global illegal markets, the author is arguing that, without taking into consideration wider social contexts, which create structural incentives for illegal markets and transnational organised crime, we can hardly understand the causes, let alone build effective strategies to combat and prevent it. Consequently, on the basis of the analyses of human trade as a form of both transnational organised crime and illegal markets, some strategies (short-term and long-term for the prevention and control of human trafficking on both the micro and macro level are suggested.

    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.

    Abuse of illegal drugs is widespread among young people, especially in the so-called "dance club scene" or "rave scene". Severe and even fatal poisonings have been attributed to the consumption of such drugs of abuse. The actions against these drugs by the Tokyo Metropolitan Government and subsequently by the Government of Japan have gone some way to reducing the potential harm caused by these substances. However, alternative products have been advertised on a number of websites. During our careful surveillance of illegal drugs in 2011, we found seven unregulated drugs advertised. This means that we have an obligation to continue strict surveillance of illegal drugs and to structure a system of temporary bans on illegal drugs.

    2001-01-01

    Megawatt pilot target experiment (MEGAPIE) is an initiative launched by Commisariat a l'Energie Atomique, Cadarache (France) and Forschungszentrum Karlsruhe (Germany) together with Paul Scherrer Institut (Switzerland), to demonstrate, in an international collaboration, the feasibility of a liquid lead bismuth target for spallation facilities at a beam power level of 1 MW. Such a target is under consideration for various concepts of accelerator driven systems (ADS) to be used in transmutation of nuclear waste and other applications world wide. It also has the potential of increasing significantly the thermal neutron flux available at the spallation neutron source SINQ for neutron scattering. SINQ's beam power being close to 1 MW already, this facility offers a unique opportunity to realize such an experiment with a reasonably small number of new ancillary systems.

    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 ad...

    This paper examines an economy with following properties. Attempts to restrain illegal immigration incur costs. Illegal workers can work only in the competitive sector. Workers and employers bargain over wages in the unionized sector and lobby the government for immigration policy and workers’ bargaining power. The main findings are as follows. If the government can determine legal immigration, then it expropriates rents from labor unions. In that case, neither workers nor employers are worse...

    Alcohol-related hepatotoxicity is not only caused by excessive alcohol consumption but also caused and even accelerated by hepatotoxic ingredients other than ethanol. Concentrations of hepatotoxic substances might be significantly high, particularly in illegally produced home-made alcohols. In this study we aim to analyze the hepatotoxic effects of a home-made alcohol traditionally called "bogma raki" in Turkey. Fifty Wistar albino male rats were used. Five groups were randomly formed with ten animals in each. Besides laboratory diets, groups were fed as follows: Group 1 (control group) distilled water; Group 2 bogma raki with distilled water (%44 (v/v), 9.2 ml/kg/day); Group 3 bogma raki with distilled water (%44 (v/v), 9.2 ml/kg/day)+walnut (10 g/kg/day); Group 4 whisky with distilled water (%40 (v/v), 9.2 ml/kg/day); Group 5 distilled water + walnut (10 g/kg/day), for 28 days. The toxicological analysis of The spirits were analyzed using Hewlett-Packard (Palo Alto, CA) GC/MS system with HP 6890 gas chromatograph, an HP 5972 mass selective detector (MSD) and an HP 6890 automatic liquid sampler GC/MS; the pressure of the carrier gas helium was 6.0 bar and the split value with a ratio of 1:100. The injection unit temperature set to 250 °C and MS quadrupole temperature set to 280 °C. The MS quadrupole detector ionization energy set to 70 eV. The initial column temperature was 60 °C (for 4 min) programmed by 6 °C/min to final temperature 160 °C and kept for 8 min at 160 °C. Utilized whisky and bogma raki samples were analyzed for the amounts of trans-anethole, ethanol, methanol, 1-propanolol, butanol, 2-butanol, 2-methyl-1-propanolol (isobutanol) and 3-methylbutanol (isoamyl alcohol). Histopathological changes in liver tissues were graded as follows; normal = 0 (illegally produced raki sample (%v/v) was as follows: trans-anethole %1.93, ethanol %95.70, 2-methyl-1-propanolol (isobutanol) %0.19, asetic acid %0.25, 3-methylbutanol (isoamyl

    In the first part of this work, a numerical simulation of the formation and of the damping of the shock wave induced in a solid target by a laser impulse is developed. It allows to interpret the experimental obtained in the second part of the study. Two series of experiments have been realized. An iron target metallographic study is intended to verify if laser shocks produce effects comparable with conventional shocks, particularly a deformation by albite twinning the existence of which is related to the shock amplitude and its evolution during the propagation in the target. Macles observation become a possible mean to estimate the value of the induced pressures. Another experiment series has been realized to determine more directly the shock parameters. Piezoelectric cermets have been used to detect a shock-wave passage and to measure the time taken to go through targets of variable thickness. The numerical solution allows, afterwards, to deduce the maximum pressure of the induced shock. The most part of the tests have been done on copper targets, the behaviour of which is well known in a large pressure domain. Some tests have been realized on aluminium and iron targets [fr

    Results of numerical model operation of the x-ray radiation spectra and values of the magnetic field induction of the laser plasma received on aluminium and copper targets under action of USP are presented in this work. In calculations the mathematcial model including combined equations of ideal magnetohydrodynamics in vie of tranpsor ot laser radiation and a self-radiation of laser plasm, supplemented by equations of state and tabulared absorption constant was used. Calculations have shown the oscillation of the x-rays in a pectral rang 1-10 keV with intensity up to 10 11 W/cm2. It is revealed that the accoutn of a heating of plasma by the laser USP changes sharply the morphology of a powerful shock plams wave. Calucation has shown that near to a surface of a target there is an oscillation of spontaneous magnetic fields with an induction about 5•10 7 Gs. And medial value of a magnetic field induction on a copper target in 1. times is more than on an aluminium target. The electron concnetration in laser plams on a copper target, on the average, in 1.3 times is more than on an aluminium target. The velocity of a motion of front of laser plama is ovservationally estimaed at an optical breakdown in atmosphere which ahs made quantity about 7.5•10 6cm/s.

    Different metal targets were investigated as possible source material for tailored laser-produced plasma-sources. In the wavelength range from 1 to 20 nm, x-ray spectra were collected with a calibrated spectrometer with a resolution of λ/Δλ = 150 at 1 nm up to λ/Δλ = 1100 at 15 nm. Intense line emission features of highly ionized species as well as continuum-like spectra from unresolved transitions are presented. With this knowledge, the optimal target material can be identified for the envisioned application of the source in x-ray spectrometry on the high energy side of the spectra at about 1 keV. This energy is aimed for because 1 keV-radiation is ideally suited for L-shell x-ray spectroscopy with nm-depth resolution. © 2011 American Institute of Physics

    This study is focused on the issue of illegal drug use among female university students preparing to become teachers. The main aim was to determine the frequency of drug abuse in a group of young women (n=215, mean age 20.44 years). Using survey methods, we determined that 33.48% of female university students in Slovakia use illegal drugs and 66.51% of students have never used illegal drugs. Differences between these groups were determined using statistical analysis, mostly in 4 areas of survey questions. We determined that education of parents has a statistically significant influence on use of illegal drugs by their children (χ2=10.14; Pillegal drug use, χ2=8.698, Pillegal drugs were interested in how their children spend their free time (68.53%). We confirmed the relationship between consumption of alcohol and illegal drug use (χ2=16.645; Pdrugs occurs most frequently at high school age. The most consumed "soft" drug in our group of female university students is marijuana. Our findings are relevant for comparison and generalization regarding causes of the steady increase in number of young people using illegal drugs.

    Some quantitative aspects of laser-irradiated pure metals, while approaching phase explosion, are still not completely understood. Here, we develop a model that describes the main quantities regulating the liquid-vapor explosive phase transition and the expulsion of liquid nanodroplets that, by solidifying, give rise to nanoparticle formation. The model combines both a thermodynamics description of the explosive phase change and a Monte Carlo simulation of the randomly generated critical vapor bubbles. The calculation is performed on a set of seven metals (Al, Fe, Co, Ni, Cu, Ag, and Au) which are frequently used in pulsed laser ablation experiments. Our final predictions about the size distribution of the liquid nanodroplets and the number ratio of liquid/vapor ejected atoms are compared, whenever possible, with available molecular dynamics simulations and experimental data.

    Melt layer erosion by melt motion is the dominating erosion mechanism for metallic armours under high heat loads. A 1-D fluid dynamics simulation model for calculation of melt motion was developed and validated against experimental results for tungsten from the e-beam facility JEBIS and beryllium from the e-beam facility JUDITH. The driving force in each case is the gradient of the surface tension. Due to the high velocity which develops in the Be melt considerable droplet splashing occurs.

    Two surveys were carried out among high school students from the Doubs region in 1982 and 1985. Their objective was to determine how legal and illegal drugs were used and their importance among the target population. Alcohol was found to be more common among the male population and its consumption remained stable during the 1982-1985 period. The use of tobacco, however, increased dramatically, especially among females attending vocational schools. The surveys also revealed that the age at which smoking was attempted for the first time has lowered, family and school environment playing an important role. Of those students who smoked, 69% had parents and a close friend who smoked, whereas 16% had none in their immediate environment who smoked. It was noted that young girls used more often psycho-active medicines than boys. A noticeable increase in their use became evident especially in vocational schools. Of those students questioned, 43% of junior high school students, 10.3% of vocational school students and 14.8% of senior high school students, stated that they used illegal drugs and that their accessibility permitted a wide use of these products. Whatever the age or sex the following associations were the most significant: drugs-tobacco, drugs-alcohol, tobacco-alcohol. Health education must therefore make the promotion of preventive strategies, concerning legal and illegal drugs, a priority in the education of adolescents.

  20. The Value Added Tax Implications of Illegal Transactions

    2011-01-01

    Full Text Available In the case of MP Finance Group CC (In Liquidation v CSARS the High Court of Appeal ruled that income "received by" a taxpayer from illegal gains will be taxable in the hands of the taxpayer. This article explores whether or not the decision in the MP Finance-case (and preceding cases on the taxation of illegal receipts can be applied to determine if illegal transactions are subject to VAT and moreover if a trader in illegal goods and services should register as a VAT vendor. 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

  1. Cytoplasmic membrane is the target organelle for transition metal mediated damage induced by paraquat in Escherichia coli

    Bacterial survival indicates that copper or iron is an essential mediator in paraquat toxicity in Escherichia coli. In this study the authors have identified the cytoplasmic membrane as a target organelle in metal-mediated paraquat toxicity and have demonstrated the complete correlation of the membrane damage with the levels of adventitious copper (or iron). The extent of membrane damage was related by use of four parameters: (a) the level of cellular ATP, (b) the level of cellular potassium, (c) the cellular capacity to accumulate and retain radiolabeled leucine, and (d) the cellular integrity as reflected by transmission electron microscopy (TEM). Exposure of bacterial cells to a combination of paraquat and copper caused a marked decline in parameters a, b, and c. This decline was found to occur in parallel with, or even to precede, the sharp loss of survival of E. coli under the same conditions. Likewise, TEM micrographs clearly indicated alternations in cellular structure that possibly reflect sites of detachment of the cytoplasmic membrane from the bacterial capsule. In contradistinction, copper alone or paraquat alone could not bring about similar changes in cellular structure. These findings are in accord with the suggested site-specific metal-mediated Haber-Weiss mechanism for paraquat toxicity and support our notion that specific chelators of transition metals could reduce or prevent the biological deleterious effects of this herbicide

    California has strict firearm-related laws and is exceptional in its regulation of firearms retailers. Though evidence suggests that these laws can reduce illegal access to guns, high levels of gun violence persist in Los Angeles (LA), California. This research seeks to describe the sources of guns accessed by active offenders in LA, California and reports offenders' motivations for obtaining guns. Los Angeles County Jail (LACJ) system (four facilities). Random sampling from a screened pool of eligible participants was used to conduct qualitative semistructured interviews with 140 incarcerated gun offenders in one of four (LACJ) facilities. Researchers collected data on firearm acquisition, experiences related to gun violence, and other topics, using a validated survey instrument. Grounded theory guided the collection and analysis of data. Respondents reported possession of 77 specific guns (79.2% handguns) collectively. Social networks facilitate access to illegal guns; the majority of interviewees acquired their illegal guns through a social connection (85.7%) versus an outside broker/unregulated retailer (8.5%). Most guns were obtained through illegal purchase (n=51) or gift (n=15). A quarter of gun purchasers report engaging in a passive transaction, or one initiated by another party. Passive gun buyers were motivated by concerns for personal safety and/or economic opportunity. In LA's illegal gun market, where existing social relationships facilitate access to guns across a diffuse network, individuals, influenced by both fear and economic opportunity, have frequent opportunities to illegally possess firearms through passive transactions. Gun policies should better target and minimise these transactions. Published by the BMJ Publishing Group Limited.

  3. Damage induced by swift heavy ions in a pure metallic target: iron. Experimental results and numerical simulation

    1993-01-01

    The damage induced when a high energy deposition occurs in the electronic system of a pure metal (Ag, Co, Fe, Ni, Pd, Pt, Ti, W, Zr) has been investigated using two methods: low temperature swift heavy ion (O, Ar, Kr, Xe, Pb, u) irradiations and computer simulations by molecular dynamics. Irradiations reveal that up to now, it is only in iron, titanium, cobalt and zirconium targets that high levels of energy deposition in electronic excitations lead to a new mechanism of defect creation in addition to the effects of elastic collisions. This mechanism might be the Coulomb explosion: the incident ion creates in its wake a cylinder of highly ionized matter; Coulomb repulsions of short duration in metallic targets could then set a great number of neighbouring atoms into motion and lead to permanent atomic displacements. Using molecular dynamics, we confirm that atomic displacements can indeed occur when neighbouring perturbated atoms receive even a very small amount of kinetic energy (≤ 1 eV). This happens only if the repulsive movements are collective and coherent. Defect creation and annealing of preexisting defects which occur in iron at different energy deposition levels are successfully simulated. An original empirical N-body potential, allowing a realistic description of the bulk properties of the body centered cubic iron, is used. (author). refs., figs., tabs

    MEGAPIE (Megawatt Pilot Target Experiment) is an initiative launched by Commissariat a l'Energie Atomique, Cadarache (France) and Forschungszentrum Karlsruhe (Germany) in collaboration with Paul Scherrer Institut (Switzerland), to demonstrate, in an international collaboration, the feasibility of a liquid lead bismuth target for spallation facilities at a beam power level of 1 MW. Such a target is under consideration for various concepts of accelerator driven systems (ADS) to be used in transmutation of nuclear waste and other applications world-wide. It also has the potential of increasing significantly the thermal neutron flux available at the spallation neutron source (SINQ) for neutron scattering. SINQ's beam power being close to 1 MW already, this facility offers a unique opportunity to realize such an experiment with a reasonably small number of new ancillary systems. The paper describes the basic features of the experiment and its boundary conditions, the technical concept of the target and underlying research carried out at participating laboratories. (author)

    The effects of fission gas pressure, uranium swelling and thermal contact conductance on the thermal-mechanical behavior of an annular target containing a low-enriched uranium foil (LEU) encapsulated in a nickel foil have been presented in this paper. The draw-plug assembly method is simulated to obtain the residual stresses, which are applied to the irradiation model as initial inputs, and the integrated assembly-irradiation process is simulated as an axisymmetric problem using the commercial finite element code Abaqus FEA. Parametric studies were performed on the LEU heat generation rate and the results indicate satisfactory irradiation performance of the annular target. The temperature and stress margins have been provided along with a discussion of the results. Copyright © 2015 Elsevier Ltd. All rights reserved.

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

    2005-06-01

    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.

  10. Illegal oral care: more than a legal issue.

    2010-12-01

    Affordable, safe and appropriate oral care, including preventive services, is not available for large parts of the world's population. In many low- and middle-income countries patients have to rely on a range of illegal oral care providers who are often socially accepted and part of the cultural context. Although filling a gap in service provision for poor populations, illegal provision of oral care is a serious public health problem, resulting in situations of low-quality care and risks for patients. It is a complex phenomenon going far beyond the legal context. It should be seen as a symptom of underlying health system and society deficits, ranging from lack of access to care and health inequities to problems of governance and law-enforcement. This paper analyses the problem based on the country case of Guyana, explores the public health, legal, professional, social, economical and ethical dimensions of the problem and proposes a differential view on illegal practice by grouping illegal oral care situations in four broad categories; each of them requiring different solutions to tackle underlying issues leading to the problem of illegal oral care.

    2017-11-07

    Illegal fishing poses a major threat to conservation of marine resources worldwide. However, there is still limited empirical research that quantifies illegal catch levels. We used the randomized response technique to estimate the proportion of divers and the quantities of loco (Concholepas concholepas) they extracted illegally. Loco have been managed for the past 17 years through a territorial user rights for fisheries system (TURFs) in Chile. Illegal fishing of loco was widespread within the TURFs system. Official reported landings (i.e., legal landings) accounted for 14-30% of the total loco extraction. Our estimates suggest that ignoring the magnitude of illegal fishing and considering only official landing statistics may lead to false conclusions about the status and trends of a TURFs managed fishery. We found evidence of fisher associations authorizing their members to poach inside TURFs, highlighting the need to design TURFs systems so that government agencies and fishers' incentives and objectives align through continuous adaptation. Government support for enforcement is a key element for the TURFs system to secure the rights that are in place. © 2017 Society for Conservation Biology.

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.

    Electroplating experiments on uranium foil have been conducted in order to develop low-enriched uranium composite targets suitable for the production of 99 Mo. Preparation of the foil surface prior to plating was found to play a key role in the quality of the resultant coating. A surface preparation procedure was developed that produces both zinc and nickel coatings with the desired level of coating adherence and coverage. Modifications of the existing plating processes now need investigation to improve to uniformity of the plating thickness, especially at the foil perimeter. (author)

    Experimental demonstration of multi-charged heavy ion acceleration from the interaction between the ultra-intense short pulse laser system and the metal target is presented. Al ions are accelerated up to 12 MeV/u (324 MeV total energy). To our knowledge, this is far the highest energy ever reported for the case of acceleration of the heavy ions produced by the laser energy of 200 TW class Ti:sapphire laser system. Adding to that, thanks to the extraordinary high intensity laser field of ∼10(21) W cm(-2), the accelerated ions are almost fully stripped, having high charge to mass ratio (Q/M).

    The Peruvian Amazon is an important arena in global efforts to promote sustainable logging in the tropics. Despite recent efforts to achieve sustainability, such as provisions in the US-Peru Trade Promotion Agreement, illegal logging continues to plague the region. We present evidence that Peru's legal logging concession system is enabling the widespread illegal logging via the regulatory documents designed to ensure sustainable logging. Analyzing official government data, we found that 68.3% of all concessions supervised by authorities were suspected of major violations. Of the 609 total concessions, nearly 30% have been cancelled for violations and we expect this percentage to increase as investigations continue. Moreover, the nature of the violations indicate that the permits associated with legal concessions are used to harvest trees in unauthorized areas, thus threatening all forested areas. Many of the violations pertain to the illegal extraction of CITES-listed timber species outside authorized areas. These findings highlight the need for additional reforms.

    Metal-organic frameworks (MOFs) have emerged as promising light-harvesting platforms for energy-transfer materials. However, the targeted construction of MOFs with desirable photophysical properties and pore structures is still a challenge. Herein, 1,1,2,2-tetrakis(4-(pyridin-4-yl)phenyl)ethene (tppe) is selected as the ligand for the construction of light-harvesting MOFs due to its highly emissive and rigid backbone, which could benefit the light-harvesting performance of the MOFs. Three MOFs (MOFs 1-3) were obtained on the basis of different metal centers (Zn 2+ and Cd 2+ ) and carboxylate building blocks. The complete structure characterization of the MOFs helps the illustration of the principles for structure tuning of this system. All three MOFs exhibit strong tppe-originated photoluminescence emission, with quantum yields as high as 47.6%. The fluorescence quantum yield and time-resolved fluorescence studies reveal that a remarkable energy-transfer efficiency (up to 96%) was achieved in this system. These results clearly indicate tppe-MOFs could be promising light-harvesting materials.

    Globally, invasive fungal infections pose a significant challenge to modern human medicine due to the limited number of antifungal drugs and the rise in resistance to current antifungal agents. A vast majority of invasive fungal infections are caused by species of Candida, Cryptococcus, and Aspergillus. Novel antifungal molecules consisting of unexploited chemical scaffolds with a unique mechanism are a pressing need. The present study identifies a dibromoquinoline compound (4b) with broad-spectrum antifungal activity that inhibits the growth of pertinent species of Candida (chiefly C. albicans), Cryptococcus, and Aspergillus at a concentration of as low as 0.5 μg/mL. Furthermore, 4b, at a subinhibitory concentration, interfered with the expression of two key virulence factors (hyphae and biofilm formation) involved in C. albicans pathogenesis. Three yeast deletion strains ( cox17Δ, ssa1Δ, and aft2Δ) related to metal ion homeostasis were found to be highly sensitive to 4b in growth assays, indicating that the compound exerts its antifungal effect through a unique, previously unexploited mechanism. Supplementing the media with either copper or iron ions reversed the strain sensitivity to 4b, further corroborating that the compound targets metal ion homeostasis. 4b's potent antifungal activity was validated in vivo, as the compound enhanced the survival of Caenorhabditis elegans infected with fluconazole-resistant C. albicans. The present study indicates that 4b warrants further investigation as a novel antifungal agent.

    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." excerpt

  2. Consistent constitutive modeling of metallic target penetration using empirical, analytical, and numerical penetration models

    Directory of Open Access Journals (Sweden)

    2016-04-01

    Full Text Available Historically, there has been little correlation between the material properties used in (1 empirical formulae, (2 analytical formulations, and (3 numerical models. The various regressions and models may each provide excellent agreement for the depth of penetration into semi-infinite targets. But the input parameters for the empirically based procedures may have little in common with either the analytical model or the numerical model. This paper builds on previous work by Riegel and Anderson (2014 to show how the Effective Flow Stress (EFS strength model, based on empirical data, can be used as the average flow stress in the analytical Walker–Anderson Penetration model (WAPEN (Anderson and Walker, 1991 and how the same value may be utilized as an effective von Mises yield strength in numerical hydrocode simulations to predict the depth of penetration for eroding projectiles at impact velocities in the mechanical response regime of the materials. The method has the benefit of allowing the three techniques (empirical, analytical, and numerical to work in tandem. The empirical method can be used for many shot line calculations, but more advanced analytical or numerical models can be employed when necessary to address specific geometries such as edge effects or layering that are not treated by the simpler methods. Developing complete constitutive relationships for a material can be costly. If the only concern is depth of penetration, such a level of detail may not be required. The effective flow stress can be determined from a small set of depth of penetration experiments in many cases, especially for long penetrators such as the L/D = 10 ones considered here, making it a very practical approach. In the process of performing this effort, the authors considered numerical simulations by other researchers based on the same set of experimental data that the authors used for their empirical and analytical assessment. The goals were to establish a

    To identify the composition of illegal and surrogate alcohol products consumed in Estonia. The initial source of information was a series of visits made in August 2005 to a soup kitchen in central Tartu, Estonia. Individuals were asked for brief details of their personal circumstances, what they normally drank, and in addition they were asked to bring samples of the substances they usually consumed. In other cases, the substances identified were purchased by the investigators or from informal contacts in north-eastern part of Estonia, an area that is well known for illegal alcohol consumption. Samples were tested for chemical contents. We identified a range of alcohol-containing substances that are consumed, although, not intended for consumption. These comprised medicinal products, aftershaves, illegally produced spirits, and fire-lighting fuel. The medicinal compounds contained, on average, 67% ethanol by volume; the aftershaves contained slightly less. Both were typically pure, with a few containing detectable quantities of isoamyl alcohol. The illegally produced alcohol contained, on average, 43% ethanol by volume, ranging from 32 to 53%. However, many also contained detectable quantities of long chain alcohols. These substances are half the price or less of commercial vodka, with fire lighting fuels especially inexpensive. There is in Estonia a range of alcohol-containing substances easily available at low cost. Some contain substantially higher concentrations of ethanol than commercial spirits and others also contain toxic long chain alcohols.

    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.

    Astatine-211 (211At) is a promising cyclotron-produced radionuclide being investigated for use in targeted alpha therapy of blood borne and metastatic cancers, as well as treatment of tumor remnants after surgical resections. The isolation of trace quantities of 211At, produced within several grams of a Bi metal cyclotron target, involves a complex, multi-step procedure: (1) Bi metal dissolution in strong HNO3, (2) distillation of the HNO3 to yield Bi salts containing 211At, (3) dissolution of the salts in strong HCl, (4) solvent extraction of 211At from bismuth salts with diisopropyl ether (DIPE), and (5) back-extraction of 211At from DIPE into NaOH, leading to a purified 211At product. Step (1) has been addressed first to begin the process of automating the onerous 211At isolation process. A computer-controlled Bi target dissolution system has been designed. The system performs in-line dissolution of Bi metal from the target assembly using an enclosed target dissolution block, routing the resulting solubilized 211At/Bi mixture to the subsequent process step. The primary parameters involved in Bi metal solubilization (HNO3 concentration and influent flow rate) were optimized prior to evaluation of the system performance on replicate cyclotron irradiated targets. The results indicate that the system performs reproducibly, having nearly quantitative release of 211At from irradiated targets, with cumulative 211At recoveries that follow a sigmoidal function. The predictable nature of the 211At release profile allows the user to tune the system to meet target processing requirements.

    Ciliwung River is the main river in the area of Jakarta that is divided into six segments across West Java and Jakarta. The study focuses on the fifth segment which is 30 km long, covering from Kelapa Dua Depok to Manggarai, South Jakarta. The survey of the river consists of 3 sub-segments: Lenteng Agung, Pejaten Timur and Manggarai. Objectives of the study are to describe the characteristics and typology of the residential surrounding the Ciliwung Segment 5 Riverbank, to identification the illegal dumping spot of solid waste, to measure the volume and composition of solid waste in the riverbank, to decide solid waste management for residential area surrounding river banks to control the river pollution. The study shows that there are 11 illegal dumping spot of solid waste consisting of 4.37 m3 solid waste volume. The average composition of solid waste consists of 44% organic, 14% woods, 12% papers, 11% plastics, 3% rubbers, 1% metals and 2% others. To control the river pollution efforts are restoring the function of riverbanks to become green open space area, installing the trash rack into the river, to manage domestic solid waste based on 3R (Reduce, Reuse, Recycle) concept.

  2. Iron-Targeting Antitumor Activity of Gallium Compounds and Novel Insights Into Triapine®-Metal Complexes

    Science.gov (United States)

    Antholine, William E.

    2013-01-01

    Abstract Significance: Despite advances made in the treatment of cancer, a significant number of patients succumb to this disease every year. Hence, there is a great need to develop new anticancer agents. Recent Advances: Emerging data show that malignant cells have a greater requirement for iron than normal cells do and that proteins involved in iron import, export, and storage may be altered in cancer cells. Therefore, strategies to perturb these iron-dependent steps in malignant cells hold promise for the treatment of cancer. Recent studies show that gallium compounds and metal-thiosemicarbazone complexes inhibit tumor cell growth by targeting iron homeostasis, including iron-dependent ribonucleotide reductase. Chemical similarities of gallium(III) with iron(III) enable the former to mimic the latter and interpose itself in critical iron-dependent steps in cellular proliferation. Newer gallium compounds have emerged with additional mechanisms of action. In clinical trials, the first-generation-compound gallium nitrate has exhibited activity against bladder cancer and non-Hodgkin's lymphoma, while the thiosemicarbazone Triapine® has demonstrated activity against other tumors. Critical Issues: Novel gallium compounds with greater cytotoxicity and a broader spectrum of antineoplastic activity than gallium nitrate should continue to be developed. Future Directions: The antineoplastic activity and toxicity of the existing novel gallium compounds and thiosemicarbazone-metal complexes should be tested in animal tumor models and advanced to Phase I and II clinical trials. Future research should identify biologic markers that predict tumor sensitivity to gallium compounds. This will help direct gallium-based therapy to cancer patients who are most likely to benefit from it. Antioxid. Redox Signal. 00, 000–000. PMID:22900955

    Analytical models were developed that describe the basic elements for metal targets irradiation in cyclotrons. Important parameters such as maximum beam current value and thermal power deposited on target were obtained and compared with practical situations. In an unprecedented way, were determined analytically the features found in intense thermal transient situations, when high protons concentrations in a small region of the beam cause intense temperature gradients in small regions of the target. Comparing with results found in the literature showed that the developed models are satisfactory, in view of all limitations of the proposed model. (author)

    Svetlichnyi, V. A.; Lapin, I. N.

    2013-10-01

    Size characteristics, structure, and spectral and luminescent properties of nanoparticles fabricated by laser ablation of zinc metal targets in water and ethanol are experimentally investigated upon excitation by Nd:YAG-laser radiation (1064 nm, 7 ns, and 15 Hz). It is demonstrated that zinc oxide nanoparticles with average sizes of 10 nm (in water) and 16 nm (in ethanol) are formed in the initial stage as a result of ablation. The kinetics of the absorption and luminescence spectra, transmission electron microscopy, and x-ray structural analysis demonstrate that during long storage of water dispersions and their drying, nanoparticles efficiently interact with carbon dioxide gas of air that leads to the formation of water-soluble Zn(CO3)2(OH)6. In ethanol, Zn oxidation leads to the formation of stable dispersions of ZnO nanoparticles with 99% of the wurtzite phase; in this case, the fluorescence spectra of ZnO nanoparticles change with time, shifting toward longer wavelength region from 550 to 620 nm, which is caused by the changed nature of defects.

    In the healthcare sector risk factors for illegal behavior and corruption are peculiar and greater than in other social areas, as it plays a crucial role in the community's economical, political and cultural life. The healthcare services is a complex network that require interaction between may people, constant contacts with the industry, safety and adequate facilities that require regular maintenance, upgrade and replacement of medical technology, connection with local and regional policy makers. This provides the opportunity of being exposed to improper influence. However, illegal behaviors can be prevented: first of all supporting all professionals that everyday work to protect our health with ethics and expertise; then with all instruments that anti-corruption action plans, such as the one introduced in Italy in 2012, aim to identify and target those areas most at risk of corruption phenomena.

    Objective To determine the prevalence of self-reported use of illegal psychoactive substances in a homeless population of the city of Cali. Method Descriptive study of prevalence of period. The target population was 763 homeless people registered during 2010 in the database provided by a temporary shelter facility in the city of Cali. Statistical analysis was performed using R version 3.2.0. Research safe according to the resolution 8430 of 1993. Results 76.9 % of the homeless population recognizes that they consume some type of illegal psychoactive substance (IPAS). The substances with a higher prevalence of use in this population were: marijuana (51.2 %), the crack cocaine (44.6 %) and cocaine (11.3 %). 28.6 % of homeless people were found to consume IPAS more than three times a day and that the main route of administration is smoke (54.7 %). 50% of respondents reported having been hospitalized at some time in a rehabilitation center. Discussion The results in this study show that the problem of PASI consumption significantly affects the population of homeless people, with marijuana and crack cocaine being the most commonly used, which is a complex situation if the easy access of these substances and the severe physical and mental degenerative effects the cause in those who consume them are taken into account. Therefore it is necessary to support initiatives aimed at intervening in this social phenomenon.

    Effective alcohol, tobacco and illegal drug policies reduce the harm to users and third parties. Knowledge about determinants and interrelations between attitudes held by the general public to different types of policy measures can benefit policy-makers who aim to increase acceptance for effective policy. The present study describes the level of support for various policy measures held by the general public, and investigates the association between attitudes to policy measures on alcohol, tobacco and illegal drug. A sample of the Norwegian general population aged 16-64 (N=1803) was interviewed by telephone. Respondents reported demographic information, personal substance use and attitudes to various policy measures. Associations between attitudes were assessed with correlation and regression analysis. Associations between attitudes were strongest for similar policy measures across substance groups (e.g. tax increases on alcohol and tobacco). There was a weaker association between attitudes to different policy measures aimed at the same substance (e.g. tax increase on alcohol and campaigns on alcohol). The degree to which people approve or disapprove of the use of particular types of policy measures is irrespective of the targeted substance. Copyright © 2015 Elsevier B.V. All rights reserved.

    Illegal drug use and abuse has increased in the Caribbean since the 1990s. In Grenada, statistical indicators such as admission rates to treatment facilities and drug arrests have provided evidence for the increased rates of illegal drug use and abuse. This study reviewed these statistical indicators and explored drug treatment options in Grenada from 2001 to 2009. A search of statistical records from the Drug Control Secretariat and the Grenada Drug Information Network/National Observatory on Drugs (GRENDIN/NOD) was performed. Literature review of relevant articles from search engines was used to support findings. Additionally, semi-structured interviews of key stakeholders from government and health agencies involved in drug prevention in Grenada were conducted to obtain information on recent developments surrounding drug arrests and treatments in Grenada. From 2001 to 2009, there were a 118% and a 23% increase in the arrest rate for males and females,respectively. There was also an increase in demand for drug treatment at the sole drug treatment facility. Preventive measures in schools and several forms of media programmes have raised awareness. However,drug use/abuse/activities still persist at a significant rate. Programmes that target improvement of treatment facilities and increased inter-agency collaboration may be successful in enhancing drug arrests and treatments.

    Countries with strict immigration policies often resort to deportation measures to reduce their stocks of illegal immigrants. Many of their undocumented foreign workers, however, are not deported but rather choose to return home voluntarily. This paper studies the optimizing behavior of undocumented immigrants who continuously face the risk of deportation, modeled by a stochastic process, and must decide how long to remain in the host country.

    2016-01-01

    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 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.

    One out of four ischemic strokes in France occurs in adults under 65 years old. About a third of them remain unexplained even after an extensive etiological assessment. A large part of these unexplained strokes could be linked to illegal drug abuse, and 10 % are estimated to be directly linked to illegal drugs in some international studies. The most frequently incriminated recreational drug remains cocaine, via several mechanisms. However, several other illegal drugs, some very commonly used such as cannabis, are suspected to have an important role in neurovascular diseases. In this article, we reviewed the epidemiological, pathophysiological and clinical studies, published in the international literature over the past 30 years. The drug-caused stroke epidemiology needs to be more precisely studied, as well as the underlying mechanisms depending on each drug. This is a public health issue that affects an economically active population, as stroke is the first cause of acquired handicap in adults.

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

    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

    The ability of short pulse laser ablation in liquids to produce clean colloidal nanoparticles and unusual surface morphology has been employed in a broad range of practical applications. In this paper, we report the results of large-scale molecular dynamics simulations aimed at revealing the key processes that control the surface morphology and nanoparticle size distributions by pulsed laser ablation in liquids. The simulations of bulk Ag targets irradiated in water are performed with an advanced computational model combining a coarse-grained representation of liquid environment and an atomistic description of laser interaction with metal targets. For the irradiation conditions that correspond to the spallation regime in vacuum, the simulations predict that the water environment can prevent the complete separation of the spalled layer from the target, leading to the formation of large subsurface voids stabilized by rapid cooling and solidification. The subsequent irradiation of the laser-modified surface is found to result in a more efficient ablation and nanoparticle generation, thus suggesting the possibility of the incubation effect in multipulse laser ablation in liquids. The simulations performed at higher laser fluences that correspond to the phase explosion regime in vacuum reveal the accumulation of the ablation plume at the interface with the water environment and the formation of a hot metal layer. The water in contact with the metal layer is brought to the supercritical state and provides an environment suitable for nucleation and growth of small metal nanoparticles from metal atoms emitted from the hot metal layer. The metal layer itself has limited stability and can readily disintegrate into large (tens of nanometers) nanoparticles. The layer disintegration is facilitated by the Rayleigh-Taylor instability of the interface between the higher density metal layer decelerated by the pressure from the lighter supercritical water. The nanoparticles emerging

    The intensities of spectral lines corresponding to 4s-4p and 3d-4p transitions in Ni atoms sputtered from metallic targets by Ar + ions were measured. The energy of primary ions was varied from 4 keV to 10 keV. Both single crystal and polycrystalline targets were used at various temperatures including ferromagnetic and paramagnetic phases. The excitation functions calculated from experimental data can be explained only by the assumption that the promotion of the electrons occurs during energetic binary collisions of atomic particles in the solid.

    The opioid epidemic in the US is affecting pregnant women and their offspring, with rising numbers of maternal and neonatal treatment episodes. The aim of this study was to characterize pregnant drug users in order to inform intervention strategies based on sociodemographic, mental health, and substance use characteristics. Data on pregnant women aged 18-44 reporting past-year, nonmedical opioid use or use of non-opioid illegal drugs (other than marijuana) were analyzed from the National Survey on Drug Use and Health (2005-2014). Women (N = 818) were categorized into 3 groups: 1) use of opioids only (n = 281), 2) opioid-polydrug users (n = 241), and 3) other (non-opioid) illegal drug users (n = 296). Characteristics between the 3 groups of women were compared using bivariable analyses. Most women were non-Hispanic White (67.6%), had a high school diploma or less education (61.0%), a household income illegal drug users (27.6%) (P drug/alcohol treatment was less prevalent among opioid-only users (6.3%) compared to opioid-polydrug users (20.3%) and other illegal drug users (8.3%) (P = 0.002). Opioid-only users also reported lower prevalence of past-year depression (P drug-using women were often of low socioeconomic status, with mental health and substance use patterns suggesting the need for targeted mental health/substance use screening and interventions before and during pregnancy, particularly for opioid-polydrug users.

    2010-01-01

    In-depth interviews were conducted in 2007 with 175 undergraduate students (94 males, 81 females, 13 non-Caucasian) at a large, public southeastern research university located in an urban area in the United States. Our primary goal was to identify how these students conceive of Attention Deficit Hyperactivity Disorder (ADHD) stimulants and their illegal use. We discovered that these students frame stimulant use as both physically harmless and morally acceptable. Specifically, these students justify their drug use through the use of four recurring prostimulant arguments: 1) comparison-and-contrast, 2) all-things-in-moderation, 3) self-medicating, and 4) minimization arguments. We discuss limitations to the study and conclude by suggesting five strategies for prevention researchers that would directly target these four arguments.

    Full Text Available Arising from the supposed negative impact of illegal immigration, including security threats as well as recent xenophobic violence, the South African Government would like to counter illegal immigration. To do this, it needs to understand the root causes of illegal immigration into the country. This article, therefore, seeks to explain and interpret why illegal immigrants make South Africa their ideal choice of destination. To provide a context, the article begins with a discussion on the research setting, that is, the South African international boundaries. Thereafter, the article discusses the concept of illegal immigration from the South African context before reviewing literature on the number of illegal immigrants in South Africa and the supposed impact. The article then explores literature on international movements and discusses established migration frameworks that explain and interpret these movements. Lastly, to confirm some facts arising from the review, we interviewed officials that manage illegal immigration as well as detained immigrants. We establish that four migration streams that have created a blended society in Southern Africa sparked illegal immigration into South Africa. The article conclude that the problem of illegal immigration into South Africa is perpetuated by deep-rooted migration networks. Therefore, if the South African Government wants to avert illegal immigration, its policy-makers should examine these roots and take them into account to arrive at a solution that is in sync with the root causes of the problem.

    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.

    2017-09-01

    The effect of spatial confinement by a solid or liquid overlayer on short pulse laser-induced surface microstructure modification is investigated in a series of large-scale atomistic simulations performed for Ag targets irradiated in the regime of melting and resolidification, below the thresholds for laser spallation and ablation. For Ag targets with free surfaces, the formation of a nanocrystalline region with random crystallographic grain orientation is observed under irradiation conditions leading to the generation of numerous sub-surface voids that slow down the solidification process. When no voids are generated, the resolidification produces grains misoriented with respect to the bulk of the target by just several degrees and separated from each other by low angle grain boundaries or dislocation walls. The presence of a liquid or solid overlayer suppresses nucleation of sub-surface voids, provides an additional pathway for cooling through the heat conduction to the overlayer, and facilitates the formation of nanocrystalline structure in a region of the metal target adjacent to the overlayer. Moreover, the stabilizing effect of the solid overlayer may result in an incomplete melting of metal in the vicinity of the interface, making it possible for grains growing from the interface to retain ;memory; of the target orientation and to produce nanocrystalline interfacial region with small misorientation of grains with respect to the bulk of the target. In all simulations, the nanocrystalline layers generated by laser processing of single crystal Ag targets are characterized by a high density of stacking faults, twin boundaries, and point defects produced in the course of the rapid resolidification.

    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

    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.

    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.

    Efforts to test slow neutron based techniques aimed at detecting and identifying illegal substances, including explosives and war gasses, are carried out at the electron linear accelerator facility in Bariloche, Argentina, as part of graduate student research work. The existing facility is used as a versatile tool to test and eventually develop detection methods apt to be used with smaller accelerators, suitable for field applications. Initial efforts to observe gamma prompt and early decay photons from irradiated samples, at one of the time-of-flight beam extraction tubes, have encouragingly paid off with a discernible signature of most of the substances tested.

    2013-07-01

    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.

    Ta-doped SnO 2 films were deposited on glass substrate (either unheated or heated at 200 °C) by reactive magnetron sputtering with a Sn–Ta metal-sintered target using a plasma control unit (PCU) and mid-frequency (mf, 50 kHz) unipolar pulsing. The PCU feedback system precisely controlled the flow of the reactive and sputtering gases (O 2 and Ar, respectively) by monitoring either discharge impedance or the plasma emission of the atomic O* line at 777 nm. The planar target was connected to the switching unit, which was operated in unipolar pulse mode. Power density on the target was maintained at 4.4 W cm −2 during deposition. The lowest obtained resistivity for the films deposited on heated substrate was 6.4 × 10 −3 Ωcm, where the deposition rate was 250 nm min −1 .

    The purpose of this study is to determine whether the current South African regulatory framework related to the illegal trade in wildlife, provides the means to regulate the illegal trade in rhino horn effectively. In an effort to combat and eradicate the illegal trade in wild species and parts therein, South Africa has enacted numerous laws and it has ratified various international conservation Conventions. However, with more than 800 rhinos having been killed in 2013 alone, it is doubtful w...

    Approved for public release, distribution unlimited The illegal drug trade has been present in Mexico since the beginning of the twentieth century when prohibition of the opium trade started. Since then, the social harm of the illegal drug trade in all its forms has been constantly increasing. Today, the most obvious example of the social harm of the illegal drug trade in Mexico is drug-related crime. As a result, Mexican authorities have launched a frontal attack against the drug cartels ...

    We investigated the prevalence of and risk factors associated with initiating nonmedical prescription opioid use (NMPOU) before and after illegal drugs using data from two linked cohort studies of street youth and adults who use illegal drugs in Vancouver, Canada. All participants who attended a study visit between 2013 and 2016 were eligible for the primary analyses. Among 512 youth and 833 adult participants, the prevalence of NMPOU was extremely high (88% among street youth; 90% among adults), and over one-third of those who reported engaging in NMPOU had initiated NMPOU before illegal drug use (vs. transitioning from illegal drugs to NMPOU). Participants who reported either transitioning to or from NMPOU had higher risk profiles, particularly related to substance use, when compared with those who reported never engaging in NMPOU. Sub-analyses restricted to only those who engaged in NMPOU found few statistically significant differences between those who initiated NMPOU prior to illegal drugs versus those who initiated illegal drugs prior to NMPOU. Findings suggest that among people who use illegal drugs, early NMPOU trajectories do not appear to critically shape future patterns and practices.

    1999-01-01

    Since the 1980s, China has experienced major changes in its traditional drug use patterns which included mostly tobacco and alcohol use. The introduction of opium, marijuana, heroin, and cocaine is the most noticeable change. In 1995, there were about 520,000 reported drug users in China and the rate of increase was about 200 percent. During the 1990 Strictly Against Illegal Drug Campaign (Yan Da), the Chinese government implemented a compulsory detoxification plan and a Community Drug Rehabilitation Camp strategy to deal with the diverse aspects of the illegal drug control. This article provides an initial evaluation of the community camp approach to drug detoxification and rehabilitation. Open-ended interviewing schedules were given to two samples from two government sponsored rehabilitation community camps in 1994. These interviews reveal that: 1) the social and cultural reorientation of drug addicts is facilitated by an intensive mass media propaganda; 2) there is a mobilization of the health care and social security systems to provide detoxification, rehabilitation, and employment to drug addicts in a relatively short period of time; 3) "recidivist" addicts and drug traffickers are condemned to a long-term incarceration in work camps; and 4) the camp strategy experiences some problems. Results show that in the two community camps, an average of twelve month's training yielded a rehabilitation rate of 80 percent.

  3. [Current situation with abortion in Colombia: between illegality and reality].

    Science.gov (United States)

    González Vélez, Ana Cristina

    2005-01-01

    This article discusses the illegality of abortion in Colombia, situating this country within the 0.4% of the world population where abortion is completely banned. Absolute criminalization of abortion turns it into a public health matter and produces social inequality. The Colombian legislation has always disregarded women as individuals and as persons in full possession of their legal rights. In contrast to a comprehensive conceptualization of sexual and reproductive rights, the various abortion bills merely refer either to "morally unacceptable" situations such as pregnancy resulting from rape or to therapeutic motives. Contradictions between illegality and reality give rise to a public discourse that features rejection of abortion practices, in keeping with the prevailing stance of the ecclesiastic hierarchy, while in practice, and at the private level, people resort to voluntary interruption of pregnancy under conditions of safety and confidentiality, at least for women from the higher socioeconomic strata. This situation not only causes social inequality but also reflects how laws lose meaning and create the collective impression of being useless or unnecessary, thus undermining the state's governing role.

    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.

    This analysis is focused on use of addictive substances among women hospitalised during delivery or puerperium. Analysed data come from National Registry of Mothers at Childbirth and from National Registry of Newborns, which are managed by the Institute of Health Information and Statistics. To describe the prevalence of addictive substances use among women during gestation and to study its relation to health complications during pregnancy, delivery or puerperium and to health status of foetus and newborns. The reporting to registries is provided in the Report on mother at childbirth and in the Report on newborn. Both registers provide basic socio-demographic information about mother, information about previous pregnancies and abortions, about current pregnancy, course of delivery, birth and neonatal treatment and health of newborn during hospitalization of mother during delivery or puerperium. Use of addictive substances is monitored in the National Registry of Mothers at Childbirth since 2000. Addictive substances are divided to tobacco, alcohol and drugs. Descriptive analysis of data was performed and binary logistic regression was used to test association of substance use with education and marital status (adjusted for age), analysis of variance was used to test association of substance use with selected health complications of pregnancy, delivery or puerperium and with health status of foetus/newborns (adjusted for age, education, marital status and interaction between addictive substances). In 2000-2009, 1,008,821 mothers were reported of whom 60,502 women were registered as cigarette smokers, 1,528 used alcohol and 1,836 used other (illegal) drugs. Total of 1,027,200 newborns were reported. The average age of mothers using addictive substances were about 0.5-3 years lower in comparison with nonusers, in average mothers using illegal drugs were the youngest. Mothers using addictive substances were more often unmarried and had lower education than nonusers

    The thesis deals with a reactive sputter process for the deposition of ITO- films. In contrast to the usual technique, the sputter targets consists of indium-tin-alloy instead of ceramic ITO. All experiments were conducted on an inline coater with 600 mm target-width. The process is stabilized by a control loop based on optical emission detection. The experiments prove, that this control loop guarantees a long term stability of the outcomes of the coating process.Process parameters, that are crucial for the optical and electrical properties of the deposited thin films are identified and studied. Among them are the flow of oxygen and the substrate temperature but also less obvious parameters such as the distance between target and substrate.Througout the work the focus is on the film deposition with pulsed plasmas. Novel bipolar DC pulse- and pulse package generators are employed for the deposition.In order to shed some light onto the influence of certain pulse parameters on the outcome of a particular coating process, a Monte-Carlo-Simulation of the particle flow in pulsed plasmas is developed. This simulation yields the distribution of particles and their respective energies on deliberately placed planes in the process chamber. Particles under investigation are both sputtered species and neutral sputter gas atoms reflected at the target. The results of this simulation provide an explanation for the influence of certain pulse parameters on the outcome of the coating process. The further investigations deal with the influence of the construction of the process chamber on the coating process. For this purpose, locally resolved optical spectra are recorded. In order to analyse these spectra, a novel connected fit algorithm is developed.This algorithm yields the distribution of certain fitparameters on the substrate. Provided the most complex of the discussed parametrizations of the dielectric function are used, these can be crucial properties such as the carrier

    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.

    A scanning electron microscope was used with a pulse-periodic CO2 laser to discover the laws governing the correlation of the modified microrelief of metal surfaces, subjected to the action of multiple laser pulses, with the emission of charged particles and the luminescence of the irradiated zone. It was established that the influence of sorption and laser-induced desorption on the emission signals may be manifested differently depending on the regime of current generation in the "target-vacuum chamber" circuit.

    Proton beams of diameters of 3 mm and 3 μm, were used to observe the differences in PIXE yield from pure metal targets encapsulated with PTFE, glass (macor) and nylon. The beam energy was kept constant at 700 keV. Beam currents varied from about 200 pA with the microbeam and between 1-10 nA with the macrobeam. Considerable enhancement was observed mainly with the use of PTFE, up to about a factor of 18 with the macrobeam and 306 with the microbeam. (author)

    Drugs consumption is as ancient as humanity. 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.

    For the first time since the year 2000 the number of death due to substance abuse of illegal drugs has increased in Germany in 2007 (+8 % compared to 2006). Emergency situations due to drug abuse are frequent, particular in big cities. They may be, however, difficult to diagnose and/or treat for an emergency physician on scene because of a lack of diagnostic tools, the local and personal surroundings, and the unknown number and nature of drugs. Many drug intoxications must be considered suicidal. On the other hand, drug intoxications may mask (other) life-threatening conditions. Emergency situations due to withdrawal offer the possibility to motivate patients to take advantage of specialist-guided abstinence programs.

    2000-02-01

    The interpretation of methamphetamine and amphetamine positive test results in biological samples is a challenge to clinical and forensic toxicology for several reasons. The effects of pH and dilution of urine samples and the knowledge about legitimate and illicit sources have to be taken into account. Besides a potentially legal prescription of amphetamines, many substances metabolize to methamphetamine or amphetamine in the body: amphetaminil, benzphetamine, clobenzorex, deprenyl, dimethylamphetamine, ethylamphetamine, famprofazone, fencamine, fenethylline, fenproporex, furfenorex, mefenorex, mesocarb, and prenylamine. Especially the knowledge of potential origins of methamphetamine and amphetamine turns out to be very important to prevent a misinterpretation of the surrounding circumstances and to prove illegal drug abuse. In this review, potential precursor compounds are described, including their medical use and major clinical effects and their metabolic profiles, as well as some clues which help to identify the sources.

  15. Illegal and Unsustainable Wildlife Hunting and Trade in Mongolia

    Directory of Open Access Journals (Sweden)

    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.

    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.

    2016-01-02

    Reality television watching and social media use are popular activities. Reality television can include mention of illegal drug use and prescription drug misuse. To determine if reality television and social media use of Twitter are associated with either illegal drug use or prescription drug misuse. Survey of 576 college students in 2011. Independent variables included watching reality television (social cognitive theory), parasocial interaction (parasocial interaction theory), television hours watched (cultivation theory), following a reality television character on Twitter, and demographics. Outcome variables were illegal drug use and prescription drug misuse. Watching reality television and also identifying with reality TV program characters were each associated with greater odds for illegal drug use. Also, following a reality TV character on Twitter had greater odds for illegal drug use and also in one analytical model for prescription drug misuse. No support was seen for cultivation theory. Those born in the United States had greater odds for illegal drug use and prescription drug misuse. Women and Asians had lower odds for illegal drug use. African Americans and Asians had lower odds for prescription drug misuse. Physicians, psychologists, and other healthcare practitioners may find it useful to include questions in their clinical interview about reality television watching and Twitter use. Physician and psychology groups, public health practitioners, and government health agencies should consider discussing with television broadcasting companies the potential negative impact of including content with illegal drugs and prescription drug misuse on reality television programs.

    Full Text Available As far as evidence in a criminal trial is concerned, Criminal Act no. 281/2003 has brought about a new procedural sanction in Romanian criminal procedure, completing article 64 in the Code of Criminal Procedure by a second para-graph, namely the exclusionary rule. The case-law of the European Court in Strasbourg is not very clear when it comes to the admissibility of illegally seized evidence against the defendant. As opposed to that, American and British common law and, following these standards, most of the traditional legal systems on the continent, acknowledge the practical use of this procedural sanction, although it is set out differently and gene-rates somewhat different effects. The said sanction is applied according to the particulars of each case, in order to achieve a just balance between the right to punish, which belongs to the state and the right to fair trial, which belongs to the suspect or the accused. In Romanian law, the unsubstantial legal provisions and the sparse case-law give no obvious answer to a series of fundamental questions related to the functioning and effects of this legal instrument: its relation to nullity, the “fruits of the poisonous tree” effect, its practical use depending on the “causes “ of illegality, the trial stage when it may be used, the procedure that governs its application and the persons entitled to benefit from this right etc. Moreover, the New Code of Criminal Procedure, in spiţe of its more complex content, tends to complicate many of the problematic issues in the current criminal procedure

    "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. The problem becomes more pressing as abortion becomes more common in a country anxious to advance in the demographic transition. Only a commitment to the reproductive health of women and the full development of their rights as citizens will

    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.

    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.

    The tackle event in rugby union ('rugby') contributes to the majority of players' injuries. Referees can reduce this risk by sanctioning dangerous tackles. A study in elite adult rugby suggests that referees only sanction a minority of illegal tackles. The aim of this study was to assess if this finding was similar in youth community rugby. Observational study. Using EncodePro, 99 South African Rugby Union U18 Youth Week tournament matches were coded between 2011 and 2015. All tackles were coded by a researcher and an international referee to ensure that laws were interpreted correctly. The inter- and intra-rater reliabilities were 0.97-1.00. A regression analysis compared the non-sanctioned rates over time. In total, 12 216 tackles were coded, of which less than 1% (n=113) were 'illegal'. The majority of the 113 illegal tackles were front-on (75%), high tackles (72%) and occurred in the 2nd/4th quarters (29% each). Of the illegal tackles, only 59% were sanctioned. The proportions of illegal tackles and sanctioning of these illegal tackles to all tackles improved by 0.2% per year from 2011-2015 (prugby players, 59% of illegal tackles were not sanctioned appropriately. This was better than a previous study in elite adult rugby, where only 7% of illegal tackles were penalised. Moreover, the rates of illegal tackles and non-sanctioned illegal tackles both improved over time. However, it is critical that referees consistently enforce all laws to enhance injury prevention efforts. Further studies should investigate the reasons for non-sanctioning.

    Full Text Available Background The Brazilian Amazon is the world’s largest rainforest regions and plays a key role in biodiversity conservation as well as climate adaptation and mitigation. The government has created a network of protected areas (PAs to ensure long-term conservation of the region. However, despite the importance of and positive advances in the establishment of PAs, natural resource depletion in the Brazilian Amazon is pervasive. Methods We evaluated a total of 4,243 official law enforcement records generated between 2010 and 2015 to understand the geographical distribution of the illegal use of resources in federal PAs in the Brazilian Amazon. We classified illegal activities into ten categories and used generalized additive models (GAMs to evaluate the relationship between illegal use of natural resources inside PAs with management type, age of PAs, population density, and accessibility. Results We found 27 types of illegal use of natural resources that were grouped into 10 categories of illegal activities. Most infractions were related to suppression and degradation of vegetation (37.40%, followed by illegal fishing (27.30% and hunting activities (18.20%. The explanatory power of the GAMs was low for all categories of illegal activity, with a maximum explained variation of 41.2% for illegal activities as a whole, and a minimum of 14.6% for hunting activities. Discussion These findings demonstrate that even though PAs are fundamental for nature conservation in the Brazilian Amazon, the pressures and threats posed by human activities include a broad range of illegal uses of natural resources. Population density up to 50 km from a PA is a key variable, influencing illegal activities. These threats endanger long-term conservation and many efforts are still needed to maintain PAs that are large enough and sufficiently intact to maintain ecosystem functions and protect biodiversity.

    Highlights: • mCusF is specifically targeted to different subcellular compartments in Arabidopsis. • Plants expressing vacuole-targeted mCusF exhibit strongest Zn resistance. • All transgenic lines accumulate more Zn under Zn exposure. • All transgenic lines enhance root-to-shoot translocation of Cd. • Metal homeostasis is improved in mCusF plants under Cd exposure. - Abstract: The periplasmic protein CusF acts as a metallochaperone to mediate Cu resistance in Escherichia coli. CusF does not contain cysteine residues and barely binds to divalent cations. Here, we addressed effects of cysteine-substitution mutant (named as mCusF) of CusF on zinc/cadmium (Zn/Cd) accumulation and resistance. We targeted mCusF to different subcellular compartments in Arabidopsis. We found that plants expressing vacuole-targeted mCusF were more resistant to excess Zn than WT and plants with cell wall-targeted or cytoplasmic mCusF. Under long-term exposure to excess Zn, all transgenic lines accumulated more Zn (up to 2.3-fold) in shoots than the untransformed plants. Importantly, plants with cytoplasmic mCusF showed higher efficiency of Zn translocation from root to shoot than plants with secretory pathway-targeted-mCusF. Furthermore, the transgenic lines exhibited enhanced resistance to Cd and significant increase in root-to-shoot Cd translocation. We also found all transgenic plants greatly improved manganese (Mn) and iron (Fe) homeostasis under Cd exposure. Our results demonstrate heterologous expression of mCusF could be used to engineer a new phytoremediation strategy for Zn/Cd and our finding also deepen our insights into mechanistic basis for relieving Cd toxicity in plants through proper root/shoot partitioning mechanism and homeostatic accumulation of Mn and Fe.

    The trend towards higher beam intensities in accelerator applications enforces the development of free surface targets in order to ensure a safe heat removal of the deposited beam energy. In the heavy-ion synchrotron facility FAIR of GSI a wide range of particle energies will be used for the production of fragments by projectile fragmentation at the fragment separator Super-FRS. For the highest power densities envisaged, a windowless vertical liquid-Li-jet-target with a rectangular shape is considered. In order to capture the whole beam dimensions within the lithium jet the variation of the jet depth over a height of 50 mm in vertical direction should not exceed more than {+-} 1%. This demands nozzle design of the target ensuring a uniform velocity profile at the nozzle exit at a simultaneously low turbulence intensity. The nozzle shape influences significantly the stability of the jet leaving the bounded duct flow. Here, mainly the turbulence distribution within the boundary layer is of importance. This extremely crucial boundary condition at the nozzle exit is a prerequisite for a reliable target operation and thus the subject of this combined experimental and numerical study. In a previous study the main parameters influencing the jet flow were elaborated, while this investigation focuses on optical velocity measurements within the boundary layer at prototypical velocities. The experimental data are compared to numerical simulations in order to validate limits of commonly used turbulence models for this type of application. (orig.)

    Sildenafil is a phosphodiesterase-5 inhibitor (PDE-5) for the treatment of erectile dysfunction. Undeclared sildenafil and related analogues adulterated in functional foods are a threat to public health. To screen these illegal drugs rapidly in herbal samples, an immunochromatographic (IC) assay was developed based on polyclonal antibodies specific to both sildenafil and its analogues. A group that is pharmacological necessary for sildenafil and its analogues was employed as a representative hapten for the generation antibodies against the target compounds. The desired antisera showed satisfactory specificities to sildenafil and major analogues with IC50 values ranging from 19.3 to 34.6 ng ml(-1) in a referring enzyme-linked immunosorbent assay (ELISA). The optimised IC assay showed detection thresholds in the range 5.0-20 μg g(-1) for sildenafil and major analogues in herbal samples. Sixty herbal food supplements were screened and six were found to be positive using the IC strip. It was confirmed by ELISA and UPLC-PDA-MS/MS that positive samples contain target illegal additives in levels of 10-40 mg g(-1) (1-4%). In this range, sensitivity of the IC strip is adequate to screen sildenafil-type compounds in herbal commodities under a dilution ratio of 1:10(3). Thus, the current IC assay is a suitable tool for screening sildenafil and its analogues as illegal additives in herbal food supplements.

    The aim of this paper is to evaluate the effect of the on-street illegal parking on the commercial travel time of the vehicles in the area. The effect of the illegal parking in the travel time of the vehicles in the zone is analyzed in an urban scenario in order to quantify the negative impact that illegal parking implies to this, by itself, congested areas. To achieve the objective of the paper, a 3x3 street model has been designed and evaluated for different situations. In this sense, based on a traffic microsimulation model a bunch of scenarios have been considered in function of parameters referred to intensity of vehicles, illegal on street parking level and location of the illegals. Based on the scenarios mentioned, it has been analyzed the effect that the different parameters have on the commercial speed of the vehicles in order to have a first set of information that permits how to act to reduce the effect of illegal on street parking. The results obtained in this article will be able to be used in next steps in order to define direct and indirect reduction strategies referred to illegal on street parking effect. (Author)

    "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." excerpt

    Illegal drug abuse, particularly prescription drug abuse is a growing problem in the United States. Research on adolescent drug abuse is based on national self-reported data. Using local coroner data, quantitative prevalence of illegal substance toxicology and trends can be assessed to aid directed outreach and community-based prevention initiatives. Retrospective analysis was conducted on all cases aged 12-17 years referred to the Office of the Medical Examiner, Clark County from 2005 to 2015 (n = 526). The prevalence of illegal opioid use in this population was 13.3%. The most commonly used drug was tetrahydrocannabinol (THC) in 29.7%. Illegal-prescription opioids and benzodiazepines were used approximately 1.7 times as much as all other illegal-drugs, excluding THC combined. The largest proportion of illicit prescription drug users were accidental death victims (p = 0.02, OR = 2.02). Drug trends by youth are ever evolving and current specific data is necessary to target prevention initiatives in local communities.

    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. Copyright © 2011 WILEY-VCH Verlag GmbH & Co.

To answer this question we set up a two-country model with search in labor markets and featuring legal and illegal immigrants among the low skilled. We calibrate it to the US and Mexican economies during the period 2000-2010. As immigrants, especially illegal ones, have a worse outside option than natives their wages are lower. Hence their presence r...

    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.

    Full Text Available As with painting a picture, perspective is one element in the composition of an image. There are first, second and third plane, the focal point and vanishing point, the latter element providing perspective and depth. That is the point where all the lines that make up an image meet. In this picture of base crime, the foreground consists of the state and market that are also the focal point, the most visible elements of the formal world responsible for public safety. The background is composed of the informal sector and the third level, in the background but drawing attention to itself, is the illegal-criminal sector, which also lies at the vanishing point: socioeconomic reproduction. This element adds depth to the entire image. All lines of the planes mentioned above are directed to and from it. It would seem that it is a major hub that explains the composition of the whole, and that is where the crux of the matter liesDOI: http://dx.doi.org/10.5377/rpsp.v1i2.1363

  18. Wild Carpathia Future Development: From Illegal Deforestation to ORV Sustainable Recreation

    Full Text Available Romanian Wild Carpathia constitutes the ultimate pristine wilderness of the old European continent. Carpathian Mountains landscape experiences and outdoor recreation represents quite unique cultural ecosystem services. The new annotations to the Forest Law are restricting any public access in the woods without authorities’ pre-approval for organised sport, leisure and tourism activities. However, off road vehicle (ORV recreation is a popular activity and a growing transparency concern of National Forest Administration Authorities that is not managed accordingly. Here we show that our ORV recreation frame model can securely allow public access and protect all Romanian mountains. Our results demonstrate how growing ORV recreation popularity can be used in an honest and open way if it is well organized and controlled. We anticipate our assay to be a starting point for a regional and national forest administration sustainable development plan. Furthermore, stopping illegal forest activities is a major target of the anti-logging movement. A well-defined assay for the ORV recreation frame model will be relevant for such developments.

    2018-03-01

    Recently, various illegal constructions occur significantly in our surroundings, which seriously restrict the orderly development of urban modernization. The 3D point cloud data technology is used to identify the illegal buildings, which could address the problem above effectively. This paper proposes an outdoor illegal construction identification algorithm based on 3D point cloud segmentation. Initially, in order to save memory space and reduce processing time, a lossless point cloud compression method based on minimum spanning tree is proposed. Then, a ground point removing method based on the multi-scale filtering is introduced to increase accuracy. Finally, building clusters on the ground can be obtained using a region growing method, as a result, the illegal construction can be marked. The effectiveness of the proposed algorithm is verified using a publicly data set collected from the International Society for Photogrammetry and Remote Sensing (ISPRS).

  20. Cultural pluralism and the future of American unity: the impact of illegal aliens.

    Science.gov (United States)

    Fuchs, L H

    1984-01-01

    This paper explores the question of the impact of illegal migration on American unity and cultural pluralism in the US. Assuming that over time the descendants of undocumented workers now in the US will behave substantially like descendants of those who immigrate legally, the long-term impact of illegal migration barely will be noticeable provided it is reduced substantially in the future. The process of acculturation will work in the same way for both groups as it has for other ethnic groups in the past, given comparable levels of education and length of family residence in the US. The author takes special notice of the illegal migration of Spanish-speaking workers and hypothesizes that the behavior of their descendants will not differ from that of the descendants of other immigrants, legal or illegal, in ways that disrupt fundamental patterns of American political unity and cultural pluralism.

  1. The Illegal Employment in Ukraine: What More Is to Be Done to Overcome It?

    Directory of Open Access Journals (Sweden)

    2017-03-01

    Full Text Available The article considers consequences of proliferation of the illegal employment in Ukraine, which are classified by the levels of administration – international, macro, meso, micro, and personal level, further by the public institutions – the State employment service, system of compulsory social insurance, pension system, judiciary, trade unions etc. The article analyzes the legislative documents as to their contribution to unshadowing the employment and legalization of wages. It has been determined that employers that provide illegal employment can be subject to administrative responsibility, criminal liability, and penalties. But, despite the available demotivators towards the illegal employment in the national legislation, its volume remains significant. Therefore we suggest the following activities to be necessary: informing citizens about the legal liability for illegal employment, activation of bodies of the State supervision and monitoring of violations of labor laws as well as working groups on legalization of the payment of wages and employment.

    Invasive species are one among many threats to biodiversity. Brazil has been spared, generically, of several destructive invasive species. Reports of invasive snakes' populations are nonexistent, but the illegal pet trade might change this scenario. Despite the Brazilian laws forbid to import most animals, illegal trade is frequently observed and propagules are found in the wild. The high species richness within Brazilian biomes and accelerated fragmentation of natural reserves are a critical...

    Food supplements are at risk from contamination with illegal ingredients on a global scale. To date, the official food control laboratory system in the UK does not appear to have been particularly active in the analytical control of illegal ingredients in food supplements. From a survey of notifications (2009 to 2016) to the European Union rapid alert system for food and feed (RASFF) food supplements are shown to be adulterated with a complex range of compounds and substances. These include p...

    Liang, Bryan A; Mackey, Tim K; Lovett, Kimberly M

    2013-05-01

    Narrow therapeutic index (NTI) drugs, because of proximity of therapeutic amounts to toxic amounts, require close professional oversight, particularly when switching formulations. However, safe use may be compromised by unsupervised switching through access to online "no prescription" Web sites. We assessed no prescription online availability of NTI drugs, using an academically published list (core NTI drugs). Using the Google search term "buy DRUG no prescription," we reviewed the first 5 search result pages for marketing of no prescription NTI drugs. We further assessed if National Association of Boards of Pharmacy (NABP) Not Recommended vendors were marketing NTI drugs. Searches were conducted from November 3, 2012 to January 3, 2013. For core NTI drugs, we found 13 of 14 NTI drugs (92%) marketed as available without prescription, all from NABP Not Recommended vendors. On the basis of these initial findings, we expanded our core list to 12 additional NTI drugs; 11 of 12 of these drugs (92%) were available from no prescription Web sites. Overall, 24 of 26 NTI drugs (92%) were illegally marketed as available online without the need for a prescription. Suspect online NTI drug access from no prescription vendors represents a significant patient safety risk because of potential patient drug switching and risk of counterfeit versions. Further, state health care exchanges with coverage limitations may drive patients to seek formulations online. Food and Drug Administration harmonization with tighter international NTI drug standards should be considered, and aggressive action against suspect online marketers should be a regulatory and public health priority.

    Whiskey produced in illegal stills (ie, "moonshine") remains an important and underappreciated source of lead toxicity in some rural counties of the Southeast. From March 5 through October 26, 1991, eight adult patients with elevated blood lead levels were identified at a rural county hospital in Alabama and were reported to the Alabama Department of Public Health notifiable disease surveillance system. A case-patient was defined as any person 17 years of age or more who presented to the hospital from January 1, 1990, through December 31, 1991, and had a blood lead level of 0.72 mumol/L or more (15 micrograms/dL or more). To identify cases and potential sources of lead exposure, we reviewed medical and laboratory records from the hospital, interviewed patients with elevated blood lead levels, and determined the lead content of moonshine samples. Nine patients met the case definition, including one patient who was not reported to the state. Patients ranged in age from 28 to 62 years; blood lead values ranged from 0.77 to 12.50 mumol/L (16 to 259 micrograms/dL). The most frequent signs of possible lead toxicity included seizures (six), microcytic anemia (five), and encephalopathy (two); one patient died. The only identified source of lead exposure for the nine patients was moonshine ingestion. Moonshine samples available from local stills contained sufficient amounts of lead (340 to 4600 mumol/L) to result in the observed blood lead levels. This investigation emphasizes the adverse health effects and ongoing public health impact of moonshine ingestion.

    Illegal trade has greatly affected marine fish stocks, decreasing fish populations worldwide. Despite having a number of aquatic species being regulated, illegal trade still persists through the transport of dried or processed products and juvenile species trafficking. In this regard, accurate species identification of illegally traded marine fish stocks by DNA barcoding is deemed to be a more efficient method in regulating and monitoring trade than by morphological means which is very difficult due to the absence of key morphological characters in juveniles and processed products. Here, live juvenile eels (elvers) and dried products of sharks and rays confiscated for illegal trade were identified. Twenty out of 23 (87%) randomly selected "elvers" were identified as Anguilla bicolor pacifica and 3 (13%) samples as Anguilla marmorata. On the other hand, 4 out of 11 (36%) of the randomly selected dried samples of sharks and rays were Manta birostris. The rest of the samples were identified as Alopias pelagicus, Taeniura meyeni, Carcharhinus falciformis, Himantura fai and Mobula japonica. These results confirm that wild juvenile eels and species of manta rays are still being caught in the country regardless of its protected status under Philippine and international laws. It is evident that the illegal trade of protected aquatic species is happening in the guise of dried or processed products thus the need to put emphasis on strengthening conservation measures. This study aims to underscore the importance of accurate species identification in such cases of illegal trade and the effectivity of DNA barcoding as a tool to do this.

    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.

    Illegal alcohol production remains as a common issue worldwide. Methanol poisoning mostly occurs because of the methanol used in production of counterfeit alcohol instead of ethyl alcohol due to its low price or by drinking the liquids containing methyl alcohol. Pectolytic enzymes results in an increase of methanol levels in many fermentation products such as ciders or wines. Methanol poisonings are infrequently encountered in forensic medicine practice. However, sporadic cases due to methanol intoxication as well as epidemic cases have been reported. In this study, we aimed to identify existence of methanol and its metabolites in illegally produced alcoholic beverages used in Antakya region. Twelve legally produced alcohol samples and Fifty-six different illegally produced alcohol samples were collected from the markets and local producers. Existence of methanol, formic acid, methyl amine, methyl formate and trioxan were determined using GC-MS method in these samples. Fifty-six different illegal alcohol samples were analyzed in this study and methanol was detected in 39 (75%) of samples. Formic acid was detected in 3, formamide in 1, methyl amine in 6, methyl formate in 10 and trioxan in 2 samples. Overwhelming majority of illegal alcoholic beverages was detected to contain methanol. Interestingly this study also revealed the presence of trioxane, which has not previously reported among toxic agents in illegal alcohol samples.

    The data from the project Conviver, launched in 2006 in Belo Horizonte (Brazil), provides a unique opportunity to study illegal electricity connections. Based on an original dataset of 15,279 low-income households, this paper studies the incidence and determinants of illegality in the context of low-income urban favelas. The probability of engaging in illegal behavior is explained not just by low income, but by a combination of concurring factors: sub-standard energy provision and equipment; inefficient/incorrect use of domestic electric appliances and running an informal in-house business. These recurrent issues in the urban favelas aggravate a sense of exclusion from growth, which is generally recognized as a trigger of illegality. The impact of energy demand on energy-related illegality is carefully analyzed, and different empirical strategies adopted to circumvent some simultaneity problem between both decision processes. The effectiveness of consumption-based energy subsidies is also explored. In spite of some contrary arguments in the literature, in the context of peri-urban slums, such measures may exert a positive impact in mitigating illegal access and use of energy. Effectiveness will be enhanced by accompanying measures such as: perceivable improvements of equipment, metering and maintenance, promotion of beneficiaries' awareness of energy usage, and energy-saving behaviors.

    2001-01-01

    Neutrinos are one of the basic subatomic particles among electrons, protons and many more, which build all matter. Neutrinos appear in three different types. Sources of neutrinos are the sun and nuclear power plants. But the type of neutrinos created there is not exactly known and the type changes between their creation to their detection, so only assumptions can be made. This change of type is called “neutrino oscillation”. In order to enable the nuclear physisists to find out more about the neutrinos and the neutrino oscillation, a neutrino factory will be built which will produce a high intensity neutrino beam with exactly known parameters like number of particles and type of neutrinos. This neutrino beam can then be used to investigate the properties of the neutrinos at near and far detectors. In cooperation with other laboratories CERN has started a study of some of the many technological challenges of a neutrino factory. A major issue of the facility is the pion production target where p...

    This technical note summarises the design calculations and experiments performed within Task #2 of the European Isotope Separation On-Line Radioactive Ion Beam Facility Design Study (EURISOL-DS) for the WTF (Windowless Transverse Film) mercury converter.A preliminary study was carried out in order to determine the heat deposition within the mercury and estimate the flow velocity needed in the film. The geometry used is based on previous analysis simulated using the Monte Carlo code FLUKA.Many experiments have been performed at IPUL to optimise an inlet nozzle capable to create a stable film. The experimental program followed to design the film former will be detailed in this report.The results of these calculations are addressing the baseline parameters. Particularly, a 1 GeV proton beam with a sigma ~2 mm Gaussian distribution impacting on a 4x30x40cm long target. The very high power density requires about 5m/s velocity in the region where the heat deposition is maximum.

  18. X-rays diagnostics of the hot electron energy distribution in the intense laser interaction with metal targets

    A two-temperature hot electron energy distribution has been revealed by modeling of bremsstrahlung emission, measured by the radiation attenuation and half-shade methods, and Kα emission from a massive silver cylinder irradiated by a subpicosecond s-polarized laser pulse with a peak intensity of about 2 × 1019 W/cm2. To deduce parameters of the hot electron spectrum, we have developed semi-analytical models of generation and measurements of the x-rays. The models are based on analytical expressions and tabulated data on electron stopping power as well as cross-sections of generation and absorption of the x-rays. The Kα emission from thin silver foils deposited on low-Z substrates, both conducting and nonconducting, has been used to verify the developed models and obtained hot electron spectrum. The obtained temperatures of the colder and hotter electron components are in agreement with the values predicted by kinetic simulations of the cone-guided approach to fast ignition [Chrisman et al., Phys. Plasmas 15, 056309 (2008)]. The temperature of the low-energy component of the accelerated electron spectrum is well below the ponderomotive scaling and Beg's law. We have obtained relatively low conversion efficiency of laser energy into the energy of hot electrons propagating through the solid target of about 2%. It is demonstrated that the assumption about a single-temperature hot electron energy distribution with the slope temperature described by the ponderomotive scaling relationship, without detailed analysis of the hot electron spectrum, can lead to strong overestimation of the laser-to-electron energy-conversion efficiency, in particular, the conversion efficiency of laser energy into the high-temperature component of the hot electron distribution.

    The aim of this study is to define a multi-criteria, web-based approach that can be used to manage the illegal dumping of solid waste, which is a serious environmental concern both in developing and developed countries. A simplified web-based geographic information system (SI-WEB-GIS) was designed to identify illegal dumpsites, and to allow sharing resources among authorities, technicians and citizens. A self-made multi-criteria technique was designed to establish the intervention priorities, in seven steps: (1) constructing the alternatives matrix; (2) giving a qualitative value or a combination of qualitative values to each individual dumpsite and to all criteria; (3) giving a numeric value to each qualitative value or combination of qualitative values in the alternatives matrix (three methods were adopted); (4) calculating the Average Hazard Index (AHI); (5) ranking the dumpsites of each alternatives matrix, in the order of decreasing AHI; (6) comparing the first 50% of the dumpsites in the three rankings, in order to evaluate which had the most intervention priorities and (7) performing a sensitivity analysis, giving different priorities to the four criteria adopted (relative quantity of waste, soil permeability level, pollution targets and types of solid waste). The application of the multi-criteria, web-based approach to managing the illegal dumping of solid waste allows minimizing the total social cost of pollution, rehabilitating dumpsites and monitoring illegal dumping. Although the system was applied to a village in Southern Italy, with around 14,000 inhabitants, it can easily be customized for use in similar villages in Italy and in other countries.

    Illegal drug use has long been a global concern. Taiwan and Korea are geographically adjacent and both countries have experienced the illegal use problems of methamphetamine, a predominant prototype of New Psychoactive Substances (NPS). NPS, a term coined by the United Nations Office on Drugs and Crime (UNODC) in recent years, have not been scrutinized for their safety and may become a new threat to public health and security worldwide. To conduct evidence-based drug policy, it is imperative to estimate the trend and pattern of illegal drug use. Therefore, this study aims to analyze and compare the current status of drug-related seizures, arrests and illegal drug use, with a focus on methamphetamine and NPS, between Taiwan and Korea. Data of illegal drug (including NPS)-related seizures and arrests were collected via anti-drug related agencies of both countries from 2006 through 2014.Since listing of NPS as controlled substances was a result of NPS abuse liability through official evaluation, the items of controlled NPS were used as an indicator of emerging use. These data obtained from Taiwan and Korea was then compared. The results showed that while methamphetamine remained as a predominant drug in both Taiwan and Korea for decades, different illegal drug use patterns have been observed in these two countries. In Taiwan, the major illegal drugs were methamphetamine, heroin, and ketamine, whereas in Korea those were methamphetamine and cannabis. By comparison of per capita illicit drug seizures, the illegal drug use situation in Taiwan was at a higher stake than that in Korea. In terms of NPS use, ketamine has been a major drug in Taiwan, but it was seldom found in Korea. Besides ketamine, the major type of NPS was synthetic cathinones in Taiwan whereas it was synthetic cannabinoids and phenethylamines in Korea. The difference in the numbers of controlled NPS items between Taiwan (23) and Korea (93) may be due to the implementation of temporary control on NPS in

    To study the characteristics and trend of illegal driving behavior in China to provide evidence for related policy enforcement. Using indices as death rate of ten thousand vehicle, death rate per 100 000 population, thousands of road mileage, degree of motorization and death ratio etc. to analyze the current situation, characteristics of illegal vehicle driving behavior related to road traffic injuries, in China. From 2006 to 2010, death ratio on vehicle road traffic injuries related to the top five illegal driving behaviors were as follows: speeding (from 0.33 down to 0.17), on refuse to give way to others (from 0.26 to 0.14), on driving without license (from 0.21 to 0.08), on illegal driving encroachment (from 0.17 to 0.04) and on reverse driving (from 0.11 to 0.07). Death rates related to vehicle road traffic injuries on drunk driving or fatigue driving were 0.04 in 2010 and 0.02 in 2010, respectively. Despite the fact that the number of vehicle road traffic injuries appeared a declining trend, the severity was increasing. Illegal driving behavior was still prevalent in China.

    To evaluate the impact of continuing illegal drug use on teenage pregnancy outcomes. Prospective cohort study. Three Australian obstetric hospitals. Four hundred and fifty-six teenage antenatal patients. Teenage antenatal patients were interviewed and completed questionnaires to establish their pattern of non-prescription drug use before and during pregnancy. Illegal drug use data provided by the participants were validated in a subgroup of 180 who were interviewed six months postpartum. Antenatal, intrapartum and postnatal outcomes were collated independently. Data were analysed using SAS. Antenatal co-morbidity, delivery and newborn outcomes. In the cohort, 20.3% used marijuana throughout their pregnancy. However, 33.5% of these were multidrug users. The remaining 79.6% did not use illegal drugs throughout pregnancy (non-users). However, half the 'non-users' were 'ex-users' who ceased drug use immediately before or during early pregnancy. Illegal drug use was associated with an increased incidence of concurrent cigarette and alcohol use (both OR > 4.1 and P 1.95 and P effects on birthweight, birthweight ratio or preterm birth. Good antenatal care may be able to ameliorate many adverse pregnancy outcomes in teenagers who use illegal drugs throughout pregnancy.

    Full Text Available A dearth of information obscures the true scale of the global illegal trade in wildlife. 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. Countries with the highest number of reports included India (n = 146, 15.6%, the United States (n = 143, 15.3%, South Africa (n = 75, 8.0%, China (n = 41, 4.4%, and Vietnam (n = 37, 4.0%. Species reported as traded or poached included elephants (n = 107, 12.5%, rhinoceros (n = 103, 12.0%, tigers (n = 68, 7.9%, leopards (n = 54, 6.3%, and pangolins (n = 45, 5.2%. The use of unofficial data sources, such as online news sites and social networks, to collect information on international wildlife trade augments traditional approaches drawing on official reporting and presents a novel source of intelligence with which to monitor and collect news in support of enforcement against this threat to wildlife conservation worldwide.

    To determine the reproductive health problems of illegal female immigrants and what obstacles they experience when seeking help for these problems. One hundred illegal female immigrants in The Netherlands aged more than 18 years were provided with a structured list of common reproductive and sexual health problems. Further semi-structured interviews were conducted regarding their experiences with reproductive health facilities. Obstacles accessing reproductive health facilities were frequently reported. Illegal female immigrants were not able to exercise control over their own reproductive and sexual health. The reasons for obstacles accessing reproductive health facilities include lack of information about reproductive health services and contraception, problems with paying for services, sexual and physical violence and fear of deportation. Obstacles accessing reproductive health facilities resulted in lacking or delayed pregnancy care (19% never received antenatal care), infrequent use of contraception and high abortion rates (64.9/1000). Of all interviewed women, 70% reported gynaecologic or sexual problems, and 28% reported past exposure to sexual violence. The reproductive health status of illegal female immigrants in The Netherlands is worrisome. There is an urgent need to empower illegal women through education. The Dutch government should make efforts to improve access to reproductive health and family planning services.

    To deploy a methodology accurately identifying tweets marketing the illegal online sale of controlled substances. We first collected tweets from the Twitter public application program interface stream filtered for prescription opioid keywords. We then used unsupervised machine learning (specifically, topic modeling) to identify topics associated with illegal online marketing and sales. Finally, we conducted Web forensic analyses to characterize different types of online vendors. We analyzed 619 937 tweets containing the keywords codeine, Percocet, fentanyl, Vicodin, Oxycontin, oxycodone, and hydrocodone over a 5-month period from June to November 2015. A total of 1778 tweets (marketing the sale of controlled substances online; 90% had imbedded hyperlinks, but only 46 were "live" at the time of the evaluation. Seven distinct URLs linked to Web sites marketing or illegally selling controlled substances online. Our methodology can identify illegal online sale of prescription opioids from large volumes of tweets. Our results indicate that controlled substances are trafficked online via different strategies and vendors. Public Health Implications. Our methodology can be used to identify illegal online sellers in criminal violation of the Ryan Haight Online Pharmacy Consumer Protection Act.

    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.

    Full Text Available In this article the authors analyze the extent and nature of illegal migration in modern Ingushetia. It noted the relationship of illegal migration and terrorism, proposed a strategy to combat this phenomenon. The authors analyzed the socio-political problems arising from uncontrolled migration flows into the country. In recent years, illegal migration in the Republic of Ingushetia has become a frequent phenomenon. Illegal migration is a real threat to regional and national security of the Russian Federation. The authors propose the concept that migration policy should be guided first and foremost the interests of national security, preservation of socio-political stability and the integrity of the territory of the Russian Federation. In this regard, it is crucial interaction of state and law enforcement agencies of all the countries involved: the outcome of, and transit of illegal migrants settling. The current socio-political conditions of life of the Ingush society, increased uncontrolled migration, national security require a tightening of migration policy.

    The use of wildlife is important for supporting the economic and demographic growth in emerging countries. Nevertheless, the products of wildlife usually come from illegal trade to supply fur, wild meat and pet markets. Illegal trade puts great pressure over wild populations and threats some endangered species. In Colombia, the trade of wildlife is important because of the volumes traded and the cultural and economic connotation of some products. We describe the spatial structure of illegal trade of wildlife at departmental level for the five most traded genera of Colombian tortoises (Trachemys, Chelonoidis, Kinosternon, Podocnemis and Rhinoclemmys). This study is based on the reports of seizures between 2005 and 2009 compiled by the Ministerio de Medio Ambiente y Desarrollo of Colombia. We apply network analysis to study and evidence that the illegal trade network of tortoises includes international markets and supplies the Andean region. The Caribbean, Pacific and Orinoquia regions are the principal suppliers. Quindio, Santander, Antioquia and Putumayo are the biggest jobbers and consumers of wild tortoises. We propose sociocultural and cohercitive actions to fragment the trade network and their illegal market as well as promoting the conservation and sustainable use of tortoises.

    Full Text Available The impacts of unregulated sport hunting can severely affect populations of target game species. Because hunting in Brazil is limited by law, obtaining data on illegal sport hunting in this country is challenging. We used an unusual online resource, YouTube™, to detect the occurrence of sport hunting in Brazil, measure the impacts of the activity on the main Brazilian game species and biomes, evaluate the opinions of hunters and internet users on sport hunting, and discuss the need for policy interventions in wildlife conservation in this country. We found 383 videos related to Brazilian sport hunting on YouTube™, accounting for more than 15 million views. Most videos were produced in the Cerrado (Brazilian savannah and approximately 70% of them depicted events of pursuit and killing of wild animals, especially lowland pacas (Cuniculus paca and armadillos (Family Dasypodidae. Videos were posted primarily in July and December, coinciding with the two main Brazilian vacation periods. Furthermore, the shotguns identified on videos show that sport hunters expend large sums of money to undertake their hunts. These results indicate that Brazilian sport hunters are possibly wealthier urban residents who travel to rural areas to hunt, contrasting with previous hunting studies in the country. Most viewers declared themselves in favor of sport hunting in comments (n = 2893 and ratings (n = 36,570 of the videos. Discussions generated by comments suggest that Brazilian sport hunters employ several informal management strategies to maintain game species stocks for future hunting and intensely question the restrictions of Brazilian environmental policies. Our results demonstrate that solutions are needed for the regulation of sport hunting in Brazil. Government actions, whether to increase surveillance or legalize hunting programs, should take into account the opinions of sport hunters and their perceptions on hunting dynamics to support effective policy

    Drug overdose is the most frequent cause of death among people who misuse illegal drugs. People who inject these drugs are 14-17 times more likely to die than their non-drug using peers. Various strategies to reduce drug-related deaths have failed to meet target reductions. Research into community-based interventions for preventing drug overdose deaths is promising. This review seeks to identify published studies describing community-based interventions and to evaluate their effectiveness at reducing drug overdose deaths. We will systematically search key electronic databases using a search strategy which groups terms into four facets: (1) Overdose event, (2) Drug classification, (3) Intervention and (4) Setting. Searches will be limited where possible to international literature published in English between 1998 and 2014. Data will be extracted by two independent reviewers using a predefined table adapted from the Cochrane Collaboration handbook. The quality of included studies will be evaluated using the Cochrane Collaboration's tool for assessing risk of bias. We will conduct a meta-analysis for variables which can be compared across studies, using statistical methods to control for heterogeneity where appropriate. Where clinical or statistical heterogeneity prevents a valid numerical synthesis, we will employ a narrative synthesis to describe community-based interventions, their delivery and use and how effectively they prevent fatal overdoses. We will publish findings from this systematic review in a peer-reviewed scientific journal and present results at national and international conferences. It will be disseminated electronically and in print. PROSPERO CRD42015017833. Published by the BMJ Publishing Group Limited.

    With a view to developing a theranostic nanomedicine for targeted drug delivery systems visible by magnetic resonance (MR) imaging, robust metal-free magnetic nanoemulsions (mean particle size less than 20 nm) consisting of a biocompatible surfactant and hydrophobic, low molecular weight 2,2,5-trimethyl-5-(4-alkoxy)phenylpyrrolidine-N-oxyl radicals were prepared in pH 7.4 phosphate-buffered saline (PBS). The structure of the nanoemulsions was characterized by electron paramagnetic resonance spectroscopy, and dynamic light scattering and small-angle neutron-scattering measurements. The nanoemulsions showed high colloidal stability, low cytotoxicity, enough reduction resistance to excess ascorbic acid, and sufficient contrast enhancement in the proton longitudinal relaxation time (T 1 ) weighted MR images in PBS in vitro (and preliminarily in vivo). Furthermore, the hydrophobic anticancer drug paclitaxel could be encapsulated inside the nanoparticles, and the resulting paclitaxel-loaded nanoemulsions were efficiently incorporated into HeLa cells to suppress cell growth. © 2017 Wiley-VCH Verlag GmbH & Co.

    The object of this theoretical study is the laminar and turbulent swirl free flow of a viscous incompressible medium in a rotation symmetric hollow jet nozzle whose geometrical configuration incorporates the technical conception of a molten metal target. Of interest is the construction of the nozzle in such a form that the wall boundaries reflect the natural frictional movement of the flow, i.e. the contours of the nozzle are trimmed by the interaction of the viscosity, momentum, gravity and surface tension forces. The mathematical treatment is based on an integral method. For laminar flow higher order polynomials were chosen and for turbulent flow the power of law of 1/7. As well as this the wall shear stresses in the turbulent flow region have to conform to the laws of pipe flow and in particular, to a modified form of Blasius' resistance law. The essential factors which are obtained from this study are the geometrical relationship between the average nozzle radius and the initial width of the fluid film, the exit angle and the Reynolds, Weber and Froude numbers as the characteristic geometric and physical flow parameters.

    Scandium-44g (half-life 3.97h) shows promise for application in positron emission tomography (PET), due to favorable decay parameters. One of the sources of 44g Sc is the 44 Ti/ 44g Sc generator, which can conveniently provide this radioisotope on a daily basis at a diagnostic facility. Titanium-44 (half-life 60.0 a), in turn, can be obtained via proton irradiation of scandium metal targets. A substantial 44 Ti product batch, however, requires high beam currents, long irradiation times and an elaborate chemical procedure for 44 Ti isolation and purification. This study describes the production of a combined 175MBq (4.7mCi) batch yield of 44 Ti in week long proton irradiations at the Los Alamos Isotope Production Facility (LANL-IPF) and the Brookhaven Linac Isotope Producer (BNL-BLIP). A two-step ion exchange chromatography based chemical separation method is introduced: first, a coarse separation of 44 Ti via anion exchange sorption in concentrated HCl results in a 44 Tc/Sc separation factor of 10 2 -10 3 . A second, cation exchange based step in HCl media is then applied for 44 Ti fine purification from residual Sc mass. In summary, this method yields a 90-97% 44 Ti recovery with an overall Ti/Sc separation factor of ≥10 6 . Copyright © 2017 Elsevier Inc. All rights reserved.

    Mesoporous silica core-shell nanospheres encapsulating a rare-earth metal complex (RC) were first synthesised through a facile W/O (water in oil) inverse microemulsion method. In order to achieve targeted complex delivery, folic acid (FA) was used as the targeting component due to its high affinity for over-expressed folate receptors (FRs) in cancer cells. The RC 2 @SiO 2 -FA nanospheres were characterised via ultraviolet-visible light absorption spectroscopy (UV-vis spectroscopy), dynamic light scattering (DLS), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). A microwave method was used to synthesise five RC cores based on 4-chlorophenoxyacetic acid, and their crystal structures were further confirmed using X-ray diffraction. The five RC cores have the following chemical formulae: [Er 2 (p-CPA) 6 (H 2 O) 6 ] RC 1 , [Ho 2 (p-CPA) 6 (H 2 O) 6 ] RC 2 , [Sm(p-CPA) 3 (H 2 O)] RC 3 , [Pr(p-CPA) 3 (H 2 O)]·3H 2 O RC 4 and [Ce(p-CPA) 3 (H 2 O) 2 ]·2H 2 O RC 5 . The carboxyl groups showed two kinds of coordination modes, namely μ 2 -η 1 :η 1 and μ 2 -η 1 :η 2 , among RC 1 -RC 5 . The flexible -OCH 2 COO- spacer group, which can undergo rotation of its C-O and C-C bonds, offered great potential for structural diversity. In vivo experiments revealed that the nanospheres exhibited no obvious cytotoxicity on HepG2 cells and 293 T cells, even at concentrations of up to 80 μg mL -1 . Nevertheless, all of the RC cores showed a certain degree of anti-tumour efficacy; in particular, RC 2 showed the strongest cytotoxicity against HepG2 cells. Interestingly, the cytotoxicity of all of the RC 2 @SiO 2 -FA nanospheres was higher than that of lone RC 2 . These types of FA-targeted mesoporous silica nanocarriers can be used for the delivery of anti-tumour RC, and provide a basis for the further study of affordable non-platinum-based complexes.

    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.

    "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. excerpt

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

    Directory of Open Access Journals (Sweden)

    Jan van der Ploeg

    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.

    Terahertz waves (THz, T-ray) lie between far-infrared and microwave in electromagnetic spectrum with frequency from 0.1 to 10 THz. Many explosives and illicit drugs show characteristic spectral features in the terahertz. Compared with conventional methods of detecting a variety of threats, such as weapons, explosives and illegal drugs, THz radiation is low frequency and non-ionizing, and does not give rise to safety concerns. Moreover, THz can penetrate many barrier materials, such as clothing and common packaging materials. THz technique has a great potential and advantage in antiterrorism and security inspection of explosives and illegal drugs due to the ability of high-sensitivity, nondestructive and stand-off inspection of many substances. The present paper summarizes the latest progress in the application of terahertz time domain spectroscopy (THz-TDS) to explosives and illegal drugs. Studies on RDX are discussed in details and many factors affecting experiments are also introduced.

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

    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.

  4. Antiproton Target

    Antiproton target used for the AA (antiproton accumulator). The first type of antiproton production target used from 1980 to 1982 comprised a rod of copper 3mm diameter and 120mm long embedded in a graphite cylinder that was itself pressed into a finned aluminium container. This assembly was air-cooled and it was used in conjunction with the Van der Meer magnetic horn. In 1983 Fermilab provided us with lithium lenses to replace the horn with a view to increasing the antiproton yield by about 30%. These lenses needed a much shorter target made of heavy metal - iridium was chosen for this purpose. The 50 mm iridium rod was housed in an extension to the original finned target container so that it could be brought very close to the entrance to the lithium lens. Picture 1 shows this target assembly and Picture 2 shows it mounted together with the lithium lens. These target containers had a short lifetime due to a combination of beam heating and radiation damage. This led to the design of the water-cooled target in...

    Directory of Open Access Journals (Sweden)

    Robert Courtney Smith

    2017-07-01

    Full Text Available This paper analyzes how the belief and fear by mostly older, white voters, politicians, and poll workers that “illegal” Latino immigrants were seeking to vote in local elections led to stigmatization of and discrimination against some Latino citizen voters in Port Chester, New York. Stoked by and closely echoing national voter ID law rhetoric, this fear fueled an “illegal Latino voter threat” narrative. This article documents how Port Chester’s leaders and citizens repeated this narrative in public life, sometimes enacting it in politics, including in voting. The resultant stigma denies Latino voters the presumed legitimacy other citizens enjoy, discrediting them in one word: illegal. Such processes harm democracy in Port Chester and America, and were on display in the 2016 presidential election.

All deliveries in Aberdeen in women using illegal drugs and women who smoked cigarettes during 1997-2007. The women who used illegal drugs were identified from a database of affected pregnant women in Aberdeen. The Aberdeen Maternity and Neonatal Databank was used to identify women who smoke cigarettes and to obtain pregnancy outcome information. Sociodemographic characteristics, maternal and perinatal outcomes were compared using chi-squared test, independent sample t-test and logistic regression analysis. Preterm delivery, low birthweight (standardized birthweight score illegal drug users, 96% were also cigarette smokers. Compared with women who smoke cigarettes with no reported illegal drug use, they were significantly more likely to have a preterm delivery [adjusted odds ratio (aOR) 1.6 (95% confidence interval (CI) 1.3-2.1)], low birthweight baby [aOR 1.9 (95%CI 1.4-2.6)], baby admitted to the neonatal unit [aOR 13.3 (95%CI 10.9-16.3)], deep vein thrombosis [aOR (95%CI 8.8-50.8)] and antepartum hemorrhage [aOR (95%CI 1.2-2.1)]. They were less likely to be at the extremes of age, or to develop pregnancy-induced hypertension [aOR 0.3 (95%CI 0.2-0.4)]. Illegal drug use in pregnancy appears to increase the risk of adverse outcomes, over and above that related to cigarette smoking, but appears to be associated with lower prevalence of gestational hypertension. © 2013 The Authors © 2013 Nordic Federation of Societies of Obstetrics and Gynecology.

    In view of the current economic crisis and the resulting austerity measures being implemented by governments across Europe, public expenditure for substance abuse treatment has increasingly become a subject of discussion. An EU cross-country comparison would allow an estimation of the total amount of public resources spent on substance abuse treatment, compare various substance abuse treatment funding options, and evaluate the division of expenditures between alcohol and illegal drugs. The purpose of this study is to estimate the public spending of EU countries for alcohol and illegal drug abuse treatment in hospitals. Our study uses a uniform methodology in order to enable valid cross-national comparisons. Our data are drawn from the Eurostat database, which provides anno 2010 data on government spending for the treatment of illegal drug and alcohol abuse in 21 EU member states. The cross-country comparison is restricted to hospitals, since data were unavailable for other types of treatment providers. The systematic registration of in- and outpatient data is essential to monitoring public expenditures on substance abuse treatment using international databases. Total public spending for hospital-based treatment of illegal drug and alcohol abuse in the 21 EU member states studied is estimated to be 7.6 billion euros. Per capita expenditures for treatment of illegal drug abuse vary, ranging from 0.1 euros in Romania to 13 euros in Sweden. For alcohol abuse, that figure varied from 0.9 euros in Bulgaria to 24 euros in Austria. These results confirm other studies indicating that public expenditures for alcohol treatment exceed that for illegal drug treatment. Multiple factors may influence the number of hospital days for alcohol or illegal substance abuse treatment, and expenditures fluctuate accordingly. In this respect, we found a strong correlation between gross domestic product (GDP) per capita and public expenditures per hospital day. The prevalence of problematic

    Full Text Available Social media is commonly used to promote social campaigns, one of which is Stop Illegal Fishing campaign. To achieve success in this campaign, some conditions have to be fulfilled i.e. positive attitudes of the social media users toward the campaigns and high intentions to provide recommendations (word of mouth to others. This study was conducted to analyze types of motivations affecting attitudes of users towards social campaigns (stop illegal fishing in social media. In addition, it also analyzed the influence of attitudes on users’ intentions in performing WOM. The method utilized to meet the objectives was Partial Least Square. The results showed that users’ motivation in using social media and towards the campaign messages are perceived to have significantly a positive effect on the attitude towards social campaigns in social media. Besides, the increase in the intention to perform WOM is positively influenced by the attitudes of social media users. There are differences identified in the motivation that affect the attitudes of social media users towards campaign of the two groups i.e. the social media users who have never seen the Stop Illegal Fishing campaign (151 samples and those who have seen the campaign in social media.    Keywords:  motivation, attitude, word of mouth, user experience, uses and gratification theory, digital campaigns, social campaigns, stop illegal fishingABSTRAKMedia sosial sering digunakan untuk mempromosikan kampanye sosial, contohnya adalah  kampanye Stop Illegal Fishing.

    Martel, Marcel

    2003-01-01

    This paper deals with the social construction of illegal drug use in the context of the counterculture movement. It looks at the actions and reactions of three groups in particular: the Ontario government, the Addiction Research Foundation of Ontario and citizens. It demonstrates that the debate about drug use took place in particular circumstances characterized by ignorance about the health consequences of illegal drug use but also within a moral panic context. Medical expertise was solicited to provide guidance to the Ontario government but it was gradually challenged by other medical groups and citizens who, by sending letters to their Provincial Premier and the Minister of Health, tried to shape public policy.

  14. Processes for the production of ultra-pure metals from oxide and their cold rolling to ultra-thin foils for use as targets and as reference materials

    2002-01-01

    A wide variety of metals have been reduced from their oxides with high (>90%) yields using metallothermic reduction, hydrogen reduction or electrowinning. The high yields during metallothermic reduction were achieved by careful design of the collector and crucible orifice. Whilst each of the three techniques gave rise to reasonably (>99%) pure metals, subsequent carefully controlled vacuum distillation, using a system with especially designed crucible, baffle and collector systems, resulted in ultra-high-purity metals being produced. Using a stainless steel pack rolling technique, metals derived either directly from the reduction routes or following subsequent distillation could be rolled to foils thinner than previously reported in the literature in the majority of cases

  15. Remote Sensing Analysis Techniques and Sensor Requirements to Support the Mapping of Illegal Domestic Waste Disposal Sites in Queensland, Australia

    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.

    This essay legally restrains the illegal content based on the e-commerce directive and introduces that the European countries detect and notify illegal content through the instructions of competent authorities, notification of credible flaggers, user reports and technical tools. The illegal content should be deleted through the service terms and transparency report basing on prevent excessive deletions system. At the same time, use filters to detect and filter to against the recurrence of illegal content. By analyzing the advantages of China under the environment of cracking down on illegal content, this essay concludes that the success of China in cracking down on illegal content lies in all-round collaborative management model of countries, governments, enterprises and individuals. At the end of the essay, one is to build a training corpus that can automatically update the ability to identify the illegal content. And it proposes an optimization scheme that establish a complete set of address resolution procedures and classify IP address data according to big data analysis and DNS protection module to prevent hackers from spreading illegal content by tampering with DNS segments.

    Seror, Nissim; Portnov, Boris A

    2018-05-01

    Construction and demolition (C&D) waste, dumped illegally in ravines and open areas, contaminates soil and can cause underground water pollution and forests fires. Yet, effective monitoring of illegal C&D waste dumping and enforcing legislation against the offenders are often a difficult task due to the large size of geographic areas that need to be monitored, and limited human and financial resources available to environmental law enforcement agencies. In this study, we use Geographic Information System (GIS) tools and geo-statistical modelling to identify the areas under potentially elevated risk of illegal C&D waste dumping in the Haifa district of Israel. As our analysis shows, locational factors, significantly associated with the accumulated amount of waste in the existing illegal C&D waste sites, include: distance to the nearest main road, depth of the ravine present at the site (pwaste dumping for future monitoring. As we suggest, the proposed approach may be useful for environmental law enforcement authorities, by helping them to focus on specific sites for inspection, save resources, and act against the offenders more efficiently.

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

    Science.gov (United States)

    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.

  7. Feathered Detectives: Real-Time GPS Tracking of Scavenging Gulls Pinpoints Illegal Waste Dumping.

    Directory of Open Access Journals (Sweden)

    Joan Navarro

    Full Text Available 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.

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

    Science.gov (United States)

    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.

    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.

    This study's objective was to analyze the use of illegal drugs by dockworkers and provide risk communication regarding the use of illegal drugs and test for infectious contagious diseases among dockworkers. This cross-sectional study including an intervention addressed to 232 dockworkers, who were individually interviewed, as well as communication of risk with testing for infectious contagious diseases for 93 dockworkers from a city in the interior of Rio Grande do Sul, Brazil. Poisson regression analysis was used. Twenty-nine workers reported the use of illegal drugs. Poisson regression indicated that being a wharfage worker, smoker, having a high income, and heavier workload increases the prevalence of the use of illegal drugs. During risk communication, two workers were diagnosed with hepatitis B (2.2%), three (3.2%) with hepatitis C, two (2.2%) with syphilis. None of the workers, though, had HIV. This study provides evidence that can motivate further research on the topic and also lead to treatment of individuals to improve work safety, productivity, and the health of workers.

The purpose of this article is to: 1 Begin a dialogue among human dimensions of wildlife scholars about the economic and cultural values of feline derivatives throughout Mexico, Central and South America; 2 Present the range of economic values that emerged in my interview and participant observation data from Costa Rica; 3 Offer an explanation of how sociological concepts influence the buying and selling of dead jaguars (Panthera onca, pumas (Puma concolor, and ocelots (Leopardus pardalis in Costa Rica. The principal results are: 1 The sociological concepts of social status and masculine identity interlace with and motivate the illegal trade; 2 The value of feline parts in Costa Rica ranges from $25 to $5000; 3 This value differs by culture and geographic residency of the seller (urban versus rural and diverged from values discovered in other countries; 4 The men who adorn their homes with illegal trophies are not necessarily the poachers. The value of jaguar skin has been recorded for as little as $100 in a 1983 study conducted in Belize and for as high as $600 in a study done in Venezuela in approximately 2011. Because of cultural differences, Cabécar sell a feline skin for as little as $25 and up to $400 if it includes teeth and nails, but Ticos, who are non-indigenous Costa Ricans, sell the skins from $500-$5000. Non-indigenous, wealthy urban men indicate prestige by the display of feline parts. My findings align with existing research that jaguar skins are sold to people in larger cities and that adornment of feline derivatives is a masculine tradition that can be linked with Amerindian cultures and ancient times. Historically jaguars have been associated with elitist symbolism and evidence in this study suggests this continues in today's culture as a sign of social status. Results suggest that money alone does not

    This work presents a fast, sensitive and reliable multi-residue methodology based on fat and protein precipitation and liquid chromatography-tandem mass spectrometry for the determination of common legal and illegal psychoactive drugs, and major metabolites, in breast milk. One-fourth of the 40 target analytes is investigated for the first time in this biological matrix. The method was validated in breast milk and also in various types of bovine milk, as tranquilizers are occasionally administered to food-producing animals. Absolute recoveries were satisfactory for 75% of the target analytes. The use of isotopically labeled compounds assisted in correcting analyte losses due to ionization suppression matrix effects (higher in whole milk than in the other investigated milk matrices) and ensured the reliability of the results. Average method limits of quantification ranged between 0.4 and 6.8 ng/mL. Application of the developed method showed the presence of caffeine in breast milk samples (12-179 ng/mL).

    Full Text Available Mining in tropical countries contributes significantly to the global minerals supplies but unregulated mining activities in reserved forests is associated with destruction, loss of habitats and loss of biodiversity. 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. Within 5 years, illegal mining had degraded 2.5 km2 (4.4% of the total area of the reserve and the destruction of cocoa farms and water sources (31. Farming among respondents reduced from 90% to 76% after illegal mining. The relatively high cost (US$ 6424.1 involved in flushing out and the subsequent return of such miners poses a threat to sustainable forest management and requires a more holistic approach in tackling such a problem.

    Drug use accounts for one of the main disease groups in Europe, with relevant consequences to society. There is an increasing need to evaluate the economic consequences of drug use in order to develop appropriate policies. Here, we review the social costs of illegal drugs, alcohol and tobacco in the European Union. A systematic search of relevant databases was conducted. Grey literature and previous systematic reviews were also searched. Studies reporting on social costs of illegal drugs, alcohol and tobacco were included. Methodology, cost components as well as costs were assessed from individual studies. To compare across studies, final costs were transformed to 2014 Euros. Forty-five studies reported in 43 papers met the inclusion criteria (11 for illegal drugs, 26 for alcohol and 8 for tobacco). While there was a constant inclusion of direct costs related to treatment of substance use and comorbidities, there was a high variability for the rest of cost components. Total costs showed also a great variability. Price per capita for the year 2014 ranged from €0.38 to €78 for illegal drugs, from €26 to €1500 for alcohol and from €10.55 to €391 for tobacco. Drug use imposes a heavy economic burden to Europe. However, given the high existing heterogeneity in methodologies, and in order to better assess the burden and thus to develop adequate policies, standardised methodological guidance is needed.

    While it is well documented that many experience harm from others' substance use, little is known about the psychological strain associated with others' use. The aims were: (1) to describe the prevalence of worries about others' alcohol, cigarette and illegal drug use, (2) whose substance use people worry about, (3) the overlap in worries, and (4) to examine how worries about others' use of each substance vary according to demographics, own substance use and experience of harm from others' use. A population survey was conducted among 16-64year old Norwegians (N=1667). Respondents' reported on worries about others' alcohol, cigarette and illegal drug use, measures of experiences of harm from others' use of the three substances, and own substance use. Worries about others' drinking were most prevalent. Among those who worried, others' cigarette and illegal drug use caused more frequent worry. While worry about cigarette use was mostly associated with family members' use, worry about others' alcohol and illegal drug use more often concerned friends'/acquaintances' use. About half worried about others' use of at least one substance. Across all three substances, experience of harm from others' substance use was most strongly related to worries. Worries about others' substance use are common and reflect the prevalence of use of the substances in the population. In sum, the findings suggest that worry about others' alcohol and illegal drug use is primarily related to acute harm while worry about others' cigarette smoking is more related to chronic harm.

    Full Text Available Background: Adolescent sexual activity, early pregnancy, induced abortion and the increase in HIV infection have become major concerns in sub-Saharan Africa and understanding adolescent sexual behaviour remains a challenge. In the Democratic Republic of Congo (DRC, the practice of illegal abortions is prevalent among school-going adolescent girls with unplanned pregnancies. Assessing their attitude and knowledge on the subject could be a starting point from which to address the problem.Objectives: To determine the knowledge of schoolgirls in Goma, DRC about the health consequences of illegal abortions and to assess their attitude towards these abortions.Method: A descriptive cross-sectional study was conducted among a randomly selected sample of 328 high school girls aged 16 to 20 years. A pre-tested, self-administered questionnaire was used for data collection. Nine out of 55 (11 public and 44 private secondary schools were randomly selected for inclusion in the study. The Epi-Info 2000 computer program was used for data capturing and analysis.Results: The different sources of information were the radio (66.2%, 217, friends (31.7%, 104, parents (1.5%, 5, and the church (0.5%, 2. The health consequences of illegal abortion mentioned were death, infertility, infection and bleeding. Of the participants, 9.8% (32 had committed an abortion before and 46% (151 knew where to obtain it; 76.2% (250 of participants were against illegal abortion, while 23.8% (78 supported it.Conclusion: Girls in secondary school in Goma had good knowledge of the illegal abortion practice and its consequences. A fifth of them were in support of the procedure. The DRC government may need to consider legalising abortion to secure a healthy future for affected girls.

  13. The Spillover of US Immigration Policy on Citizens and Permanent Residents of Mexican Descent: How Internalizing "Illegality" Impacts Public Health in the Borderlands.

    The militarization of the US-Mexico border region exacerbates the process of "Othering" Latino immigrants - as "illegal aliens." The internalization of "illegality" can manifest as a sense of "undeservingness" of legal protection in the population and be detrimental on a biopsychological level. We explore the impacts of "illegality" among a population of US citizen and permanent resident farmworkers of Mexican descent. We do so through the lens of immigration enforcement-related stress and the ability to file formal complaints of discrimination and mistreatment perpetrated by local immigration enforcement agents, including local police authorized to enforce immigration law. Drawing from cross-sectional data gathered through the National Institute of Occupation Safety and Health, "Challenges to Farmworker Health at the US-Mexico Border" study, a community-based participatory research project conducted at the Arizona-Sonora border, we compared Arizona resident farmworkers (N = 349) to Mexico-based farmworkers (N = 140) or Transnational farmworkers who cross the US-Mexico border daily or weekly to work in US agriculture. Both samples of farmworkers experience significant levels of stress in anticipation of encounters with immigration officials. Fear was cited as the greatest factor preventing individuals from reporting immigration abuses. The groups varied slightly in the relative weight attributed to different types of fear. The militarization of the border has consequences for individuals who are not the target of immigration enforcement. These spillover effects cause harm to farmworkers in multiple ways. Multi-institutional and community-centered systems for reporting immigration-related victimization is required. Applied participatory research with affected communities can mitigate the public health effects of state-sponsored immigration discrimination and violence among US citizen and permanent residents.

    2007-01-01

    A substantial proportion of pathological gamblers engage in gambling-related illegal behavior. We examined differences in baseline characteristics and treatment outcomes in two groups: pathological gamblers who did and did not commit gambling-related illegal acts in the year before treatment. Participants were 231 pathological gamblers enrolled in a randomized study of treatment that included cognitive behavior therapy and referral to Gamblers Anonymous (GA). Participants reporting recent illegal behavior (n = 63) endorsed more severe lifetime and recent (past-year) gambling disorder symptoms and higher gambling-related debt than did gamblers who denied illegal behavior (n = 168). Those who reported illegal behavior also maintained a significantly higher severity of gambling disorder throughout treatment, although both groups experienced similar improvements in gambling symptoms over time. While pathological gamblers with or without gambling-related illegal behavior appeared to improve at a similar rate regardless of the treatment provided, more intensive treatment may be warranted for individuals with gambling-related illegal behavior, as they demonstrated greater gambling severity throughout treatment and follow-up.

    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.

    Full Text Available Building up the borders of Europe, their militarization and turning refugees into illegal human beings are the key approaches of the EU towards people fleeing to survive. Thus, Europe is turning its border areas into crisis conditions and exports its policies, under economic duress, into third countries. Simultaneously, it is enhancing its control apparatus that infringes into lives of EU citizens. However, the creation of a class of unwanted people benefits EU economies in parallel with the militarization of the EU borders, which empowers the military–security industry, the smuggler networks grow. The ways to reach Europe are becoming ever more deadly. Anthropologist Ruben Andersson, author of the book Illegality, Inc. and Martin Lemberg-Pedersen, adjunct professor at the Centre for Advanced Migration Studies at the University of Copenhagen, emphasize and warn about these developments – the article is based on interviews with each of them.

    2015-01-01

    This study draws on in-depth interviews and focus group discussions with young adults in a metropolitan area of the Philippines to examine perceptions and practices of illegal abortion. Study participants indicated that unintended pregnancies are common and may be resolved through eventual acceptance or through self-induced injury or ingestion of substances to terminate the pregnancy. Despite the illegality of abortion and the restricted status of misoprostol, substantial knowledge and use of the drug exists. Discussions mirrored broader controversies associated with abortion in this setting. Abortion was generally thought to invoke gaba (bad karma), yet some noted its acceptability under certain circumstances. This study elucidates the complexities of pregnancy decisionmaking in this restrictive environment and the need for comprehensive and confidential reproductive health services for Filipino young adults.

    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.

  3. Risk classification for nuclear facilities in connection with the illegal use of nuclear materials

    1976-01-01

    It is shown, and illustrated by an example, that specific conditions at a nuclear facility to a large extent determine the probability of a successful illegal attack against that facility. Therefore, a categorization of nuclear materials according to the associated hazards alone, as practised currently, does not appear to be sufficient for the establishment of a balanced national physical protection system. In this paper a possible way of categorizing nuclear facilities according to the associated risks, determined as objectively as possible, is discussed. It is felt that initially the analysis should be restricted to the determination of the conditional risks, associated with illegal acquisition and use of radioactive materials by a postulated hostile or similar group.

  5. Automatic detection of potentially illegal online sales of elephant ivory via data mining

    Julio Hernandez-Castro

    2015-07-01

    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 deals with optimal income and commodity taxation in an economy, where alcohol is an externality-generating consumption good. In our model, alcohol can be bought domestically, imported (via border trade) or produced illegally. Border trade implies an incentive to set the domestic alcohol tax below the marginal social damage of alcohol, and to tax (subsidize) commodities which are complementary with (substitutable for) alcohol. In addition, since leisure and alcohol consumption are g...

    2017-11-01

    Peru has one of the richest primate faunas of any country. The illegal trade in wild primates is one of the largest threats to this fauna in Peru. We characterize the illegal trade in primates through empirical and ethnographic data. We collected data from traffic routes and centers throughout Peru and evaluate current efforts to combat this traffic. Based on our findings from 2,070 instances of wildlife crime involving 6,872 primates, we estimate the domestic trade in primates for pets and bushmeat in Peru in the hundreds of thousands per year, with the larger bodied Atelidae facing the highest direct consequences. We found that government authorities lack sufficient staff, capacity, resources, infrastructure, and protocols to efficiently combat illegal trade in primates. Also, the complicated legal framework and lack of cooperation and antagonism with the public further limit these efforts. Wildlife authorities in Peru are able to confiscate only a fraction of primates traded and mostly intervene in cases of private pet owners rather than traffickers. We estimate that the current rate of illegal trade in primates is comparable to levels of trade prior to the 1973 ban on primates' exportation. The combination of direct observations on primate trade and ethnographic data allows a comprehensive look at primate trade in Peru. We call upon decision makers and international funders to channel their efforts toward "on the ground" actions such as increasing the ability of the authorities to act, giving them "in action" training in law enforcement and establishing strict control measures against corruption.

    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.

  13. Illegal bowling actions contribute to performance in cricket finger-spin bowlers.

    2018-02-07

    With advances in technology, scientists are now able to more accurately measure elbow displacement changes during the cricket bowling action. This has led to the realization that the majority of bowlers undergo some degree of elbow extension during the forward swing phase of bowling. Consequently, the International Cricket Council were obliged to revise the once zero tolerance for elbow extension threshold to a 15° range. However, it is still not understood if bowling with >15° of elbow extension aids performance or alters other kinematic movements. The purpose of this study was to compare performance and technique measures between legal and illegal finger-spin bowlers. Data were collected from 48 pathway and elite bowlers using a 22-camera motion analysis system. Results indicated that the ball velocity and revolutions at ball release of pathway bowlers with illegal actions showed no significant difference and were similar to elite legal bowlers. Technique differences were also identified, with illegal bowlers being more front-on, forcing a reliance on increased elbow flexion and supination to impart effective ball kinematics at ball release. The performance benefit of greater ball velocity and revolutions is obtained when finger-spin bowlers deliver the ball with more than the allowable 15° of elbow extension, thus reinforcing the validity of the current bowling laws. To counteract bowling with an illegal action, it is recommended that a more side-on technique at back foot impact and rotating the trunk through to the point of ball release will assist bowlers in reducing undesirable elbow extension levels. © 2018 John Wiley & Sons A/S.

    This chapter concerns poaching and other illegal fishing activities in the Amur, the border river separating Russia and China. Both Russian and Chinese citizens take part in these activities, which have greatly reduced the number of fish in the river Other factors have also significantly contributed to a reduction of fish stocks, such as industrial development on areas adjacent to the river, outdated technology, deforestation and generally poor environmental conditions. However, reports issue...

    Highlights: • NPs formed in a plasma-plume during laser irradiation of metals (Al, Ti, Ag) were studied. • In situ SAXS and ex situ TEM, XRD and Raman spectra were measured. • NPs size decreased when increasing the O{sub 2} fraction in a controlled O{sub 2}+N{sub 2} atmosphere. • The oxidation of metal NPs in the plasma restricts the increase of the size of the NPs. - Abstract: The influence of a reactive atmosphere on the formation of nanoparticles (NPs) in the plasma plume generated by nanosecond pulsed laser irradiation of metal targets (Ti, Al, Ag) was probed in situ using Small Angle X-ray Scattering (SAXS). Air and different O{sub 2}–N{sub 2} gas mixtures were used as reactive gas within atmospheric pressure. SAXS results showed the formation of NPs in the plasma-plume with a mean radius varying in the 2–5 nm range. A decrease of the NPs size with increasing the O{sub 2} percentage in the O{sub 2}–N{sub 2} gas mixture was also showed. Ex situ observations by transmission electron microscopy and structural characterizations by X-ray diffraction and Raman spectroscopy were also performed for powders collected in experiments done using air as ambient gas. The stability of the different metal oxides is discussed as being a key parameter influencing the formation of NPs in the plasma-plume.

    Cyprus is recognised as a hotspot for illegal bird trapping in the Mediterranean basin. A consumer demand for the Eurasian blackcap (Sylvia atricapilla) is driving the use of non-selective trapping methods, resulting in the indiscriminate killing of millions of migratory birds. Efforts to tackle the issue have so far been characterised mostly by a top-down approach, focusing on legislation and enforcement. However, trapping levels are not decreasing and conflict between stakeholder groups is intensifying. To understand why efforts to stop illegal bird trapping have not been effective, we used semi-structured interviews to interview 18 local bird trappers and nine representatives from the pertinent environmental non-governmental organisations (NGOs) and the governmental agencies responsible for enforcing the legislation. We found distinct differences between the views of the local trapping community and the environmental NGOs, particularly on why trapping is occurring and its impact on the avifauna. This disparity has contributed to misrepresentations of both sides and a high degree of conflict, which is potentially proving counterproductive to conservation interventions. In addition, it appears that trappers are a heterogeneous group, likely driven by various motivations besides profit. We argue that stakeholders interested in reducing illegal bird trapping need to develop anti-poaching strategies that aim at minimising the disparity in the views, and subsequently the conflict, acknowledging also that trappers are not a homogenous group, as often treated.

    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.

    To understand the phenomenon of consumption of surrogate and illegal alcohols in Tallinn, capital of Estonia. This study, conducted in Tallinn in May 2006, used rapid situation assessment. Interviews with key informants in relevant settings such as emergency departments of hospitals, accommodation for the homeless, police etc. (n = 22), with alcohol abusers (n = 33), natural observations of surrogate sale and consumption venues (n = 46), and tracking of trade data were carried out. Key informants confirmed that consumption of illegal and surrogate alcohols are widely used by alcohol abusers, a finding confirmed by the alcohol abusers. Availability of surrogates varied by area of the city, mainly sold from street kiosks. Illegally produced spirits were also easily available. Sales of surrogates appear to have increased in recent years. A range of alcohol-containing substances that appear to be easily available at low cost, and that have high concentration of ethanol or contaminants known to be toxic, were identified in Tallinn. Alcohol policies in Estonia should address the consumption and availability of these substances.

    We decided to determine if there were differences in the nutritional and health status among illegal immigrant adolescents from Morocco and Algeria. We performed a retrospective cross-sectional study (1997-2003); 120 male adolescents (86 Moroccans and 34 Algerians) admitted to protection centers of Zaragoza City were assessed. The nutritional status was assessed using the anthropometric method. The health status was assessed according to a standardized medical and laboratory protocol. The mean age (SDU) of the Moroccans was 15.9 (1.2) years and the mean age of the Algerians was 15.6 (1.5) years. Significantly lower values of weight (p = 0.027), upper arm circumference (p = 0.0005) and subscapular skinfold thickness (p = 0.023) along with a significantly higher incidence of ferritin isolated deficiency (p = 0.027; odds ratio = 7.54; 95% CI, 0.96-59.32) were observed in the Moroccan adolescents. Illegal immigrant adolescents from Morocco had a significantly lower nutritional and iron reserves status than that observed in illegal immigrant adolesents from Algeria.

  1. Limits of Brazil's Forest Code as a means to end illegal deforestation.

    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.

    Opium poppy products are often illegally used for both recreational and medicinal purposes. In order to demonstrate the ingestion of opium poppy substances, morphine, codeine and their metabolites have been identified. However, morphine and codeine also originate from the ingestion of therapeutic drugs. Therefore, thebaine, one of the main opium alkaloids, in hair was suggested as a marker for chronic use of illegal opium poppy substances in the present study. First, thebaine was included in the analyte list of our routine analytical method for the simultaneous quantification of codeine, morphine, norcodeine, normorphine and 6-acetylmorphine (6-AM) in hair, which was fully validated previously. Then, the incorporation of thebaine and other opiates into hair and the effect of hair pigmentation were examined using lean Zucker rats with both dark grey and white hair on the same body. Thebaine was also measured in hair samples from actual cases of opium poppy substance use. Consequently, thebaine in hair was demonstrated as a marker of chronic use of illegal opium poppy substances using an animal study and actual cases. Thebaine and other opiates were successfully measured in pigmented hair from rats that ingested raw opium suspension. Moreover, thebaine identified in hair excluded possibility of ingestion of pharmaceutical opiates in actual cases. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    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.

    This study aimed to describe, compare, and predict mental health outcomes of different migrant groups and native residents in Switzerland. Asylum seekers (n=65); refugees holding permanent protection visas (n=34); illegal migrants (n=21); labor migrants (n=26); and residents (n=56) completed an assessment by questionnaire. Main outcome variables were symptoms of posttraumatic stress, anxiety and depression. It was tested whether resident status predicted psychopathology over and above the influence of control variables including social desirability, traumatic event types and post-migration resources. Asylum seekers (54.0%) and refugees (41.4%) fulfilled criteria of PTSD most frequently. Clinically relevant symptoms of anxiety and depression were most frequently reported by asylum seekers (84.6% and 63.1%, resp.) and illegal migrants (both 47.6%). Resident status contributed to psychopathology over and above the influence of control variables. Overall, asylum seekers, refugees, and illegal migrants showed high psychiatric morbidity. Differences in resident status appear to be specifically associated with mental health outcomes. This association persists even when controlling for social desirability, post-migration resources and traumatic events. This emphasizes the importance of current socio-political living conditions for mental health, even with respect to the psychopathological sequelae of past traumatic experiences.

    2018-02-01

    Costal monitoring is focused on fast response to illegal immigration and illegal ship traffic. Especially, the illegal ship traffic has been present in media since April 2015, as the number of reported deaths of immigrants crossing the Mediterranean significantly increased. Satellite images provide a possibility to at least partially control both types of events. This paper defines the principal criteria to select the best satellite constellation architecture for maritime and coastal monitoring, filling the gaps of imagery techniques in term of real-time control. The primary purpose of a constellation is to obtain global measurement improving the temporal resolution. The small size and low-cost are the main factors, which make CubeSats ideal for use in constellations. We propose a constellation of 9 Cubesats distributed evenly in 3 different planes. This reduces the revisit time enhancing the coverage duration. In addition, it also allows observing fire, damage on building and similar disasters. In this analysis, the performance criteria were reported such as the revisit time, the vision duration and the area coverage.

    Customs investigation and drug enforcement services are interest in a rapid and reliable identification of smugglers and dealers. In contrast workplace testing and traffic controls are aiming at the detection of intoxicated persons via the determination of illegal narcotics in body fluids like urine or blood. DRUGWIPE is a pen size, test strip based immunochemical detector for narcotic contaminations on surfaces. It is extremely simple to apply and takes about two minutes to read test results without depending upon any further technical means. This paper describes the applicability of DRUGWIPE to identify drug smugglers or dealers as well as consumers. With respect to the situation and the initial suspicion the test indicates handling as well as consumption. In cooperation with the Institute for Legal Medicine in Munich suspicious drivers were examined with DRUGWIPE for the abuse of illegal narcotics. Test results from this test series are presented and compared with the results from the blood or urine analysis. The question whether the detected traces of illegal narcotics on the body surface of suspicious drivers are combing transpiration or external contamination are discussed.

  7. Selective metal binding to Cys-78 within endonuclease V causes an inhibition of catalytic activities without altering nontarget and target DNA binding

    T4 endonuclease V is a pyrimidine dimer-specific DNA repair enzyme which has been previously shown not to require metal ions for either of its two catalytic activities or its DNA binding function. However, we have investigated whether the single cysteine within the enzyme was able to bind metal salts and influence the various activities of this repair enzyme. A series of metals (Hg2+, Ag+, Cu+) were shown to inactivate both endonuclease Vs pyrimidine dimer-specific DNA glycosylase activity and the subsequent apurinic nicking activity. The binding of metal to endonuclease V did not interfere with nontarget DNA scanning or pyrimidine dimer-specific binding. The Cys-78 codon within the endonuclease V gene was changed by oligonucleotide site-directed mutagenesis to Thr-78 and Ser-78 in order to determine whether the native cysteine was directly involved in the enzyme's DNA catalytic activities and whether the cysteine was primarily responsible for the metal binding. The mutant enzymes were able to confer enhanced ultraviolet light (UV) resistance to DNA repair-deficient Escherichia coli at levels equal to that conferred by the wild type enzyme. The C78T mutant enzyme was purified to homogeneity and shown to be catalytically active on pyrimidine dimer-containing DNA. The catalytic activities of the C78T mutant enzyme were demonstrated to be unaffected by the addition of Hg2+ or Ag+ at concentrations 1000-fold greater than that required to inhibit the wild type enzyme. These data suggest that the cysteine is not required for enzyme activity but that the binding of certain metals to that amino acid block DNA incision by either preventing a conformational change in the enzyme after it has bound to a pyrimidine dimer or sterically interfering with the active site residue's accessibility to the pyrimidine dimer

  8. MUNICIPAL SOLID WASTE ILLEGAL DUMPING AND IT’S SPATIAL AUTOREGRESSION: THE CASE OF THE REPUBLIC OF KOREA

    2016-11-01

    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.”

    2013-02-01

    Several chemical elements are required by living organisms in addition to the four elements carbon, hydrogen, nitrogen and oxygen usually present in common organic molecules. Many metals (e.g. sodium, potassium, magnesium, calcium, iron, zinc, copper, manganese, chromium, molybdenum and selenium) are known to be required for normal biological functions in humans. Disorders of metal homeostasis and of metal bioavailability, or toxicity caused by metal excess, are responsible for a large number of human diseases. Metals are also extensively used in medicine as therapeutic and/or diagnostic agents. In the past 5000 years, metals such as arsenic, gold and iron have been used to treat a variety of human diseases. Nowadays, an ever-increasing number of metal-based drugs is available. These contain a broad spectrum of metals, many of which are not among those essential for humans, able to target proteins and/or DNA. This mini-review describes metal-containing compounds targeting DNA or proteins currently in use, or designed to be used, as therapeutics against cancer, arthritis, parasitic and other diseases, with a special focus on the available information, often provided by X-ray studies, about their mechanism of action at a molecular level. In addition, an overview of metal complexes used for diagnosing diseases is presented.

    Bioturbation alters the properties of sediments and modifies contaminant bioavailability to benthic organisms. These naturally occurring disturbances are seldom considered during the assessment of sediment quality. We investigated how the presence (High bioturbation) and absence (Low bioturbation) of a strongly bioturbating amphipod within three different sediments influenced metal bioavailability, survival and bioaccumulation of metals to the bivalve Tellina deltoidalis. The concentrations of dissolved copper decreased and manganese increased with increased bioturbation. For copper a strong correlation was observed between increased bivalve survival (53–100%) and dissolved concentrations in the overlying water. Increased bioturbation intensity resulted in greater tissue concentrations for chromium and zinc in some test sediments. Overall, the results highlight the strong influence that the natural bioturbation activities from one organism may have on the risk contaminants pose to other organisms within the local environment. The characterisation of field-based exposure conditions concerning the biotic or abiotic resuspension of sediments and the rate of attenuation of released contaminants through dilution or readsorption may enable laboratory-based bioassay designs to be adapted to better match those of the assessed environment. - Highlights: • Bioturbation intensity modifies metal exposure and outcomes of sediment bioassays. • Sediment fluxes of Cu decrease and Mn and Zn increase with increased bioturbation. • Strong correlations between bioaccumulated and dissolved Cd, Cr, Pb, Zn, Cu and Ni. • Weak correlations between bioaccumulated and particulate metals. - This study investigated the impact of sediment bioturbation intensity on metal bioavailability and toxicity to aquatic organisms, and the implications of this to toxicity test design.

    Individuals with gambling disorder are at an elevated risk for engaging in gambling-related illegal behaviors. The present study examined client (N = 88) and clinician ratings (N = 30) of client characteristics associated with a history of gambling-related illegal behaviors. We also examined client characteristics associated with history of arrest for a gambling-related crime. Gambling-related illegal behaviors and arrest were common (57.3% and 23.9%, respectively) in the present sample. Clients of younger age, and those with greater gambling-related financial consequences, lifetime alcohol problems, impulsivity, mood symptoms, and daily living role difficulties were more likely to report gambling-related illegal behaviors. Clients who had been arrested for a gambling-related crime were more likely to report daily living and role functioning difficulties and lifetime alcohol problems. Clinicians rated clients with a history of gambling-related illegal behaviors and/or gambling-related arrests as more impulsive, and clinicians also endorsed higher rates of treatment failure among these clients. Both client and clinician report suggested that clients with a history of illegal behaviors may have a variety of comorbid problems that may be a focus of clinical intervention.

    Small angle x-ray scattering was used to probe in-situ the formation of nanoparticles in the plasma plume generated by pulsed laser irradiation of a titanium metal surface under atmospheric conditions. The size and morphology of the nanoparticles were characterized as function of laser irradiance. Two families of nanoparticles were identified with sizes on the order of 10 and 70 nm, respectively. These results were confirmed by ex-situ transmission electron microscopy experiments.

  17. Drivers of illegal livelihoods in remote transboundary regions: the case of the Trans-Fly region of Papua New Guinea

    Directory of Open Access Journals (Sweden)

    2018-03-01

    Full Text Available Remote transboundary regions in developing countries often contain abundant natural resources. Many of these resources are being overexploited to supply an ever-increasing demand from Asia, often via illegal cross-border trade. Understanding the systemic issues that drive households to engage in illegal activities in transboundary regions is a prerequisite for designing effective interventions and diverting livelihoods toward sustainable trajectories, but is rarely applied. This study analyzed the drivers of illegal trade in marine products, e.g. sea cucumber, shark fin, and fish bladders, among coastal villages in Papua New Guinea that border Indonesia and Australia in the Trans-Fly region. Mixed-methods (household questionnaire surveys, focus group discussions, and key informant interviews were applied to triangulate results and minimize denial bias, which is a challenge when studying illegality. Results indicated that distance from markets and economic centers was the main driver for engagement in illegal activity, and distance from a center was also the main driver of poverty. Contrary to studies elsewhere, we found that poverty did not generally drive households' engagement in illegal trade. Only in Daru, the primary economic hub, where immigrants from the areas impacted by the Ok Tedi mine operations have resettled, were the poorest households likely to be involved in illegal trade, because they had no alternative sources of livelihood. Weak governance exacerbates the situation, which includes corruption, a lack of enforcement, and poor coordination among government levels, and a breakdown of traditional resource management systems. Respondents highlighted that current bilateral border agreements are outdated and cannot account for modernization, a globalizing economy, and communities' rapid transition to a cash economy. Our findings emphasize the need to find innovative governance solutions to manage this stressed social

    Low socioeconomic position predicts risk of substance abuse, yet few studies tested the role of preexisting familial and individual characteristics. Data come from the TEMPO (Trajectoires Epidémiologiques en Population) study (community sample in France, 1991-2009, n=1103, 22-35 years in 2009) set up among offspring of participants of an epidemiological study (GAZEL). Past 12-month substance use was assessed in 2009 by self-completed mail survey: regular tobacco smoking, alcohol abuse (AUDIT), cannabis use, problematic cannabis use (CAST), other illegal drug use. Socioeconomic position was defined by educational attainment, occupational grade, employment stability and unemployment. Covariates included demographics (age, sex, relationship status, parenthood), family background (parental income, parental tobacco smoking, parental alcohol use), and juvenile characteristics (psychological problems, academic difficulties) measured longitudinally. 35.8% of study participants were regular smokers, 14.3% abused alcohol, 22.6% used cannabis (6.3% had problematic cannabis use) and 4.1% used other illegal drugs. Except for alcohol abuse, substance use rates were systematically higher in individuals with low, rather than intermediate/high, socioeconomic position (age and sex-adjusted ORs from 1.75 for cannabis use to 2.11 for tobacco smoking and 2.44 for problematic cannabis use). In multivariate analyses these socioeconomic disparities were decreased, but remained statistically significant (except for illegal drugs other than cannabis). Tobacco smoking, alcohol, cannabis and polysubstance use are common behaviors among young adults, particularly those experiencing socioeconomic disadvantage. Interventions aiming to decrease substance abuse and reduce socioeconomic inequalities in this area should be implemented early in life. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    Reports from the World Health Organization have suggested that counterfeit medicines pose a serious problem in developing countries. An investigation of anti-erythropoietin antibody-mediated pure red cell aplasia in Thailand found evidence of drug smuggling, which may have serious safety implications. This study assessed the authenticity and quality of epoetin alfa samples in Thailand. Samples of epoetin alfa-prefilled syringes were collected from the pharmacies at 2 major hospitals (62 samples), 8 retail pharmacies (41 samples), and Thai authorities (30 samples confiscated from smugglers at 2 airports, and 6 samples from a condominium used by smugglers). These samples were tested against the European Union Pharmacopeia specifications for aggregate content in epoetins of packaging components (eg, batch number, expiration date, appearance, letter size), and company's confidential features (eg, nature of the ink, type and quality of the paper, other covered features) were also investigated. The main outcome measures were protein aggregate content, determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis and Western blotting; and isoform distribution, assessed by isoelectric focusing and Western blotting. Epoetin alfa samples obtained from the company's cold-chain and authorized distribution channels met all quality standards, as did all epoetin alfa samples obtained from the hospital pharmacies. However, evidence showed that some samples were being smuggled or sold illegally through certain unauthorized retail pharmacies. The epoetin alfa samples obtained from both airports and the condominium were stored improperly at room temperature. Aggregate levels exceeded the specification of packaging were found to be authentic. This investigation found evidence that some epoetin alfa samples were smuggled into Thailand without proper cold chain, contained high levels of protein aggregates, and were sold illegally through certain retail pharmacies.

    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.

    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.

    Full Text Available The region of Campania (particularly Naples and Caserta has experienced an emergency in the waste management cycle during past years. Although the most critical phase has been overcome after the construction of the incineration plant in Acerra (an old-fashioned technology built up over a few months, whose impact on environment and health has not yet been assessed, most of the underlying problems have not been resolved. The illegal burning of wheels, plastics, textiles, and other industrial residuals, along with the detection of two thousand toxic substance dumping sites, still represents major concerns of environmental pollution and population health. This review summarizes the most relevant studies, which analyzed chemical contamination (primarily dioxins and polychlorinated biphenyls (PCBs of the air, soil, water, animals, and humans in Campania. In addition, we reviewed information on population health (i.e., mortality data, congenital malformations, and cancer incidence. Moving from a detailed mapping of (mostly illegal waste dumping sites in Campania, we have focused on recent studies which have found: (a high concentrations of dioxins (≥5.0 pg TEQ/g fat in milk samples from sheep, cows, and river buffaloes; (b remarkable contamination of dioxin and PCBs in human milk samples from those living in the Naples and Caserta areas (PCDDs+PCDFs and dioxin-like-PCBs (dl-PCBs assessed at 16.6 pg TEQ/g of fat; range: 7.5–43 pg/g of fat; (c potential age-adjusted standardized mortality rates associated with some specific cancer types; (d a statistically significant association between exposure to illegal toxic waste dumping sites and cancer mortality, even after adjustment by socio-economic factors and other environmental indicators.

    Full Text Available Objective. This article sought to describe knowledge, attitudes, and practices regarding the use of legal and illegal substances by nursing students from Cartagena (Colombia. Methodology. This was a descriptive study conducted on a probabilistic sample of 689 students matriculated in three nursing programs. The study used the Predisposing Factors instrument associated to the use of psychoactive substances by Cepeda, Aldana, and Ossío. Results. The mean age of the participants was 20.5 years, 91.9% were women, 92.4% belonged to socio-economic levels 1 to 3, 87.5% were single. Of the 12 psychoactive substances (PAS consulted, eight were considered by over 90% of the students as harmful to health. A total of 94% considered that the brain is the organ most affected by drug consumption. The students considered production (80.4%, trafficking (79.4%, and use of substances (80.0% as problems of great importance; and they agreed with investing financial resources for prevention, rehabilitation, and follow-up programs for the population affected (89.1%. They expressed that use of PAS is mainly influenced by friends (26.9% and by family problems (26.7%. The highest life prevalence of legal PAS use were: alcohol (77.6% and cigarettes (17.6%; along with marihuana for illegal PAS use (1.8%. Conclusion. Knowledge of nursing students on legal and illegal PAS is not satisfactory, although they have favorable attitudes for their prevention and control. Use of PAS by the students, although not of great magnitude, is a problem deserving attention from organisms in charge of university welfare programs. Curricular contents should be enhanced on the phenomenon of PAS use of future nursing professionals.

    Economic recessions may influence illegal drug use via different mechanisms, for example increased use due to more psychological distress or decreased use due to lower incomes and purchasing power. This paper reviews the literature on how economic recessions and unemployment affect the use of illegal drugs among adults. We conducted a systematic realist literature review, which is an explanatory method that aims to understand underlying mechanisms that connect an event to an outcome in a specific context. A systematic search was performed in EconLit, Embase, Medline, PsycINFO, SocIndex, and Web of Science for studies examining mechanisms explaining how recessions or unemployment affect illegal drug use. We synthesized 28 studies published between 1990 and 2015. Most evidence (17 studies) was found for the counter-cyclical mechanism that recessions and unemployment increase psychological distress, which increases drug use. Mainly supportive evidence for this mechanism was found in several high quality studies, in different contexts, and in a diverse number of countries and samples. In contrast, decreased income did not seem to decrease drug use (10 studies). Little evidence was available on the non-working time mechanism (4 studies) and the social exclusion mechanism (5 studies). Most of the studies that did examine these latter mechanisms confirmed the hypothesized counter-cyclical associations. The current evidence is in line with the hypothesis that drug use increases in times of recession because unemployment increases psychological distress which increases drug use. During times of recession, psychological support for those who lost their job and are vulnerable to drug use (relapse) is likely to be important. Copyright © 2017 The Author(s).

    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.

  8. The importance of distinguishing illegality from guilt in trials for alleged medical malpractice

    2012-10-01

    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.

    The aims of this study are to: (1) describe the prevalence and sociodemographic characteristics of inhalant use among middle and high school students in Brazil, and (2) test the hypothesis of inhalants being intermediate drugs between legal and illegal drug use. A representative sample of 5226 students from private schools in São Paulo, Brazil, was selected to answer a self-report questionnaire. Weighted data was analyzed through Cox proportional hazards models. In the overall sample, inhalants seems to be an intermediate drug, since prior inhalant initiation was associated with first marijuana use, adjusted for previous alcohol and tobacco initiation.

    Full Text Available The paper examines the question of the burden of proof for the facts that imply illegal immission as prerequisite of in rem removal claim. The approach is different to the standard doctrine and it is in according to the general rule of the burden of proof in litigation - so called modified norm theory. In the centre of the attention is distinction of so called constitutive and impeditive facts, and criteria for distinction. The implementation of modified norm theory regarding issue of this paper shows that primal distinguishing point is not suitable, so the other modification methods should be applied, in order to get the answer.

    A new minoxidil analogue was detected in an illegal dietary supplement advertised as a hair-growth treatment. The analogue was identified using ultra-performance liquid chromatography (UPLC), high-resolution mass spectrometry (LC-HR-MS) and nuclear magnetic resonance (NMR) spectroscopy. The compound was structurally elucidated as a minoxidil analogue in which the piperidinyl group of minoxidil was replaced with a pyrrolidinyl group corresponding to a molecular formula of C 8 H 13 N 5 O. The new analogue has been named triaminodil. As this is the first report of the compound, there are no chemical, toxicology or pharmacological data available.

    Bioturbation alters the properties of sediments and modifies contaminant bioavailability to benthic organisms. These naturally occurring disturbances are seldom considered during the assessment of sediment quality. We investigated how the presence (High bioturbation) and absence (Low bioturbation) of a strongly bioturbating amphipod within three different sediments influenced metal bioavailability, survival and bioaccumulation of metals to the bivalve Tellina deltoidalis. The concentrations of dissolved copper decreased and manganese increased with increased bioturbation. For copper a strong correlation was observed between increased bivalve survival (53-100%) and dissolved concentrations in the overlying water. Increased bioturbation intensity resulted in greater tissue concentrations for chromium and zinc in some test sediments. Overall, the results highlight the strong influence that the natural bioturbation activities from one organism may have on the risk contaminants pose to other organisms within the local environment. The characterisation of field-based exposure conditions concerning the biotic or abiotic resuspension of sediments and the rate of attenuation of released contaminants through dilution or readsorption may enable laboratory-based bioassay designs to be adapted to better match those of the assessed environment.

  14. Influence of plasma-induced energy deposition effects, the equation of state, thermal ionization, pulse shaping, and radiation on ion-beam-driven expansions of plane metal targets

    International Nuclear Information System (INIS)

    Long, K.A.; Tahir, N.A.

    1986-01-01

    In a previous paper by Long and Tahir [Phys. Fluids 29, 275 (1986)], the motion of plane targets irradiated by ion beams whose energy deposition was assumed to be independent of the ion energy, and the temperature and density of the plasma, was analyzed. In this paper, the analytic solution is extended in order to include the effects of a temperature-and density-dependent energy deposition as a result of electron excitation, an improved equation of state, thermal ionization, a pulse shape, and radiation losses. The change in the energy deposition with temperature and density leads to range shortening and an increased power deposition in the target. It is shown how the analytic theory can be used to analyze experiments to measure the enhanced energy deposition. In order to further analyze experiments, numerical simulations are presented which include the plasma-induced effects on the energy deposition. It is shown that since the change in the range is due to both decrease in density and the increase in temperature, it is not possible to separate these two effects in present experiments. Therefore, the experiments which measure the time-dependent energy of the ions emerging from the back side of a plane target do not as yet measure the energy loss as a function of the density and temperature of the plasma or of the energy of the ion, but only an averaged loss over certain ranges of these physical quantities

    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.

    The escalating illegal wildlife trade (IWT) is one of the most high-profile conservation challenges today. The crisis has attracted over US$350 million in donor and government funding in recent years, primarily directed at increased enforcement. There is growing recognition among practitioners and policy makers of the need to engage rural communities that neighbor or live with wildlife as key partners in tackling IWT. However, a framework to guide such community engagement is lacking. We developed a theory of change (ToC) to guide policy makers, donors, and practitioners in partnering with communities to combat IWT. We identified 4 pathways for community-level actions: strengthen disincentives for illegal behavior, increase incentives for wildlife stewardship, decrease costs of living with wildlife, and support livelihoods that are not related to wildlife. To succeed the pathways, all require strengthening of enabling conditions, including capacity building, and of governance. Our ToC serves to guide actions to tackle IWT and to inform the evaluation of policies. Moreover, it can be used to foster dialogue among IWT stakeholders, from local communities to governments and international donors, to develop a more effective, holistic, and sustainable community-based response to the IWT crisis. © 2016 The Authors.

    A better understanding of the experiences of young people before, during and after belonging to an illegal armed group (IAG) can provide information to promote their reintegration into urban settings in Colombia and to help prevent violence. A qualitative study with a hermeneutic historical approach was performed to examine these experiences from the perspective of direct or indirect participants in the armed conflict. Fifty individuals aged 14-24 years (7 women and 43 men) with low socioeconomic status from Medellín were interviewed; 26 of them had a history of direct experience with IAGs. What stands out in their stories are descriptions of obstacles to progress in their lives; lives marked by stigma, poverty, violence and inequality; the differences of opinion among these young people regarding whether to belong to these illegal groups; how becoming an active member of an IAG creates both an opportunity for the present and an additional obstacle for the future, which adds complexity to the risk behaviors they assume; and how the reintegration process offers new expectations regarding access to educational and employment opportunities and social recognition. All of these factors point to the need for not only a comprehensive reintegration process but for more inclusive and equitable social policies, in this case for children and young people.

  18. Trait psychopathy, emotional intelligence, and criminal thinking: Predicting illegal behavior among college students.

    2015-01-01

    Research focusing on individuals high on trait psychopathy remains limited. Higher trait psychopathy is associated with lower levels of emotional intelligence and increased participation in illegal behavior. Additionally, research has confirmed significantly higher levels of criminal thinking and lower levels of empathy in the incarcerated psychopathic population. However, the relationships between trait psychopathy and criminal thinking have not been researched in the community or college population. To test for such differences, questionnaires containing relevant measures were administered to 111 college students. Results indicated that higher levels of trait psychopathy were significantly related to less caring for others, intrapersonal understanding, and general mood, and greater interpersonal functioning and stress management. Furthermore, trait psychopathy was a strong predictor of violent, property, drug, and status offenses. Power-oriented criminal thinking was also predictive of violent behaviors, and entitlement predicted property offending. Results suggest emotional intelligence is important for predicting psychopathy, and trait psychopathy is a strong predictor of all types of illegal behaviors among the non-incarcerated population.

    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.

    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.

    Overcrowded motor vehicle crashes caused by the very active criminal enterprise of smuggling illegal immigrants in the desert of the Southwest is a recent and under-recognized trauma etiology. A computerized database search from 1990 through 2003 of local newspaper reports of overcrowded motor vehicle crashes along the 281 miles of Arizona's border with Mexico was conducted. This area was covered by two level I trauma centers, but since July 2003 is now served only by the University Medical Center. Each of these crashes involved a single motor vehicle in poor mechanical shape packed with illegal immigrants. Speeding out of control on bad tires, high-speed rollovers result in ejection of most passengers. Since 1999, there have been 38 crashes involving 663 passengers (an average of 17 per vehicle) with an injury rate of 49 per cent and a mortality rate of 9 per cent. This relatively recent phenomenon (no reports from before 1998) of trauma resulting from human smuggling is lethal and demonstrates the smugglers' wanton disregard for human life, particularly when facing apprehension. Even a few innocent bystanders have been killed. These crashes overwhelm a region's trauma resources and must be recognized when planning the distribution of trauma resources to border states.

    Full Text Available The fastest growing form of gambling in the world is online gambling. This studyis the first step to understanding thereasons behind the mushrooming of illegalonline gambling shops around the three provincesas well as the response by thelocal law enforcement agenciesregarding the scourge. The qualitative componentconsisted of interviews with focus groups from the three selected provinces ofLimpopo, Gauteng and North West. From thefindings it emergedthat illegal onlinegambling operators have the same mode of operationacross the three provinces.The interior and exterior of their shops looks exactly the same. Access controls tothe inside of these shops are all controlled by security gates, security personnel andcameras. Slots machines that are played by punters are also the same within thethree provinces that are comparable. The most common slots game machine foundare sizzling hot, cool diamonds, heart of gold, lucky reels, fire queen, crazy cows,kiss, rainbow riches, and little pigs. Through intensive enquiriesby the first author,it has surfaced that software of these slots machines are sourced from foreigncountries like Greece, Russia, Malta, Finland and Bulgaria. According to reliableinformation obtain from one syndicate member by the researcher, this software isnot sold to illegal online gambling owners in South Africa, but they pay a retainerfee every month to access the software.Based on the above findings,recommendations are provided to assist relevant stakeholders to address thesituation.

    Do shame and guilt help people avoid doing wrong? Although some research suggests that guilt-proneness is a protective factor while shame-proneness puts individuals at risk, most research is either cross-sectional or short-term. In this longitudinal study, 380 5th graders (ages 10–12) completed measures of proneness to shame and guilt. We re-interviewed 68% of participants after they turned 18 years old (range 18–21). Guilt-proneness assessed in childhood predicted fewer sexual partners, less use of illegal drugs and alcohol, and less involvement with the criminal justice system. Shame-proneness, in contrast, was a risk factor for later deviant behavior. Shame-prone children were more likely to have unprotected sex and use illegal drugs in young adulthood. These results held when controlling for childhood SES and teachers’ ratings of aggression. Children’s moral emotional styles appear to be well established by at least middle childhood, with distinct downstream implications for risky behavior in early adulthood. PMID:24842762

    We aimed to assess the effects of exposure to tobacco smoke, alcohol and illegal drugs during early pregnancy on the head circumference (HC) at birth of otherwise healthy neonates. A follow-up study from the first trimester of pregnancy to birth was carried out in 419 neonates. An environmental reproductive health form was used to record data of substance exposure obtained during the first obstetric visit at the end of the first trimester. A multiple linear regression model was created for this purpose. Alcohol intake during pregnancy and medical ionizing radiation exposure were the most significant predictors of HC. The mothers' alcohol consumption increased with the mothers' and fathers' education level, net family income and fathers' alcohol consumption. In contrast, maternal smoking decreased with increasing mothers' and fathers' education level and net family income. About 13% of the surveyed embryos were exposed to illegal drugs. Mild to moderate alcohol consumption diminishes the at-birth HC of theoretically healthy newborns in a linear form. There was no threshold dose. We perceived a need for increasing the awareness, and for training, of health care professionals and parents, in regard to risks of alcohol consumption and for recommending abstinence of these substances in both parents during pregnancy. It should also be remembered that medical ionizing radiation should be performed only during the first half of the cycle in fertile women. We think that our study has an important social impact as it affords data for implementing policies for promoting "healthy pregnancies".

    Full Text Available The impact of Hispanic immigration phenomenon, especially of the illegal one on the economy at local, state andfederal level is a major concern in the U.S.. Challenges to effective control at the borders of the United States haveincreased dramatically in recent decades.The problem of the present research is the extent to which budgetary policy restricted the illegal immigrationphenomenon and what were the negative consequences of the policy to strengthen the borders?The purpose of this analysis is to check if there is a significant relationship between the Border Patrol budget and thenumber of apprehensions at the border. The results of the research indicate that the two variables are closely linked,and the trend is that with the increase of the budget, the number of border apprehensions drops. The results wereanalyzed in two phases during 1990-2000 and 2001-2011. For both periods, it shows that the connection between thetwo chosen variables is statistically strong. However, factors such as political, social and economic resulted in adifferent correlation between the Border Patrol budget and the number of apprehensions

    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%.

    International food transit is a risk to public and animal health when not subject to legal importation sanitation procedures. Due to the extensive border area, illegal food import in Brazil is a common practice, especially in Rio Grande do Sul (RS), a state that borders with Argentina and Uruguay. The objective of this study was to evaluate the profile of Brazilians living in cities in RS that border with Argentina (BR-AR) or Uruguay (BR-UR) regarding the practice of illegal import of products of animal origin and to determine associations between the population characteristics and illegal import. A questionnaire with information related to the personal profile, habits of acquisition of imported food, and knowledge of health risks deriving from the consumption of the imported products was elaborated. The questionnaire was administered in six cities in RS (three cities bordering Argentina and three cities bordering Uruguay) and responses were obtained from 744 individuals. The variables city, sex, level of education, and knowledge were subjected to the chi-square test to verify the association between these variables and food import. Part of the interviewees admitted to illegally importing products of animal origin at both BR-AR (65.17%) and BR-UR (76.28%) borders. Dairy products were the main imported goods, followed by raw and processed meat. The study revealed that illegal import is common at the frontier region of RS, especially that of products of animal origin, dairy, and raw and processed meat. Although illegal importation occurs at all the cities under study, it was higher at the BR-UR border. Also, knowledge of the health risks influences the decision to import food or not.

    In the case of digital piracy should rights be publicly or privately enforced? The emergence of large-scale anti-piracy laws and the existence of non-monitored illegal channels raise important issues for the design of digital anti-piracy policies. In this paper, we study the impact of these two enforcement settings (public vs. private) in the presence of an illegal non-monitored outside option for users. Taking account of market outcomes, we show that in both cases, the optimal strategies of ...

    The biologically and clinically important membrane transporters are challenging proteins to study because of their low level of expression, multidomain structure, and complex molecular dynamics that underlies their activity. ATP7B is a copper transporter that traffics between the intracellular compartments in response to copper elevation. The N-terminal domain of ATP7B (N-ATP7B) is involved in binding copper, but the role of this domain in trafficking is controversial. To clarify the role of N-ATP7B, we generated nanobodies that interact with ATP7B in vitro and in cells. In solution NMR studies, nanobodies revealed the spatial organization of N-ATP7B by detecting transient functionally relevant interactions between metal-binding domains 1–3. Modulation of these interactions by nanobodies in cells enhanced relocalization of the endogenous ATP7B toward the plasma membrane linking molecular and cellular dynamics of the transporter. Stimulation of ATP7B trafficking by nanobodies in the absence of elevated copper provides direct evidence for the important role of N-ATP7B structural dynamics in regulation of ATP7B localization in a cell.

    The aim of the present investigations was to find markers for differentiating between the consumption of illegal cannabis products and legal medication containing fully synthetic Δ9-tetrahydrocannabinol (Δ9-THC), e.g., Marinol capsules. Δ9-Tetrahydrocannabinolic acid A (Δ9-THCA-A) and Δ9-tetrahydrocannabivarinic acid A (Δ9-THCVA-A) were taken into consideration for analysis, because these substances are the precursors of Δ9-THC and Δ9-tetrahydrocannabivarin (Δ9-THCV) in plant material of Cannabis sativa and are not contained in medical THC formulations. Whereas Δ9-THCA-A is an already well investigated substance, there is little analytical data on Δ9-THCVA-A. The reason for the presented investigations was a case in which a man was tested positive for Δ9-THC during a routine traffic control claiming that the positive serum sample resulted from the intake of a THC medication (Marinol) and not from consuming illegal cannabis products. Sample preparation consisted of a protein precipitation with acetonitrile. Analysis was carried out on a Thermo Fisher LCQ Deca ion trap LC-MS-MS-system using electron spray ionization (ESI) in negative mode. MS(2)- and MS(3)-full scan spectra were recorded for Δ9-THCA-A and Δ9-THCVA-A starting from [M-H](-). Reference spectra were obtained by measuring a Δ9-THCA-A reference solution and an ethanolic cannabis extract for Δ9-THCVA-A as there is no reference material for this cannabinoid available on the market yet. Main transitions for Δ9-THCA-A were m/z 357→313 and 339 in the MS(2)-spectrum and m/z 313→245 and 191 in the MS(3)-spectrum. Fragmentation pattern of Δ9-THCVA-A was identical with a difference of 28 amu less for the precursor ion as well as the fragments due to a shorter alkyl side chain in the molecule (MS(2): m/z 329→285 and 311; MS(3): m/z 285→217 and 163). The two plant cannabinoids Δ9-THCA-A and Δ9-THCVA-A could be detected in the serum sample by LC-MS-MS which proved the intake of illegal

    This technical note summarises the design calculations performed within Task #2 of the European Isotope Separation On-Line Radioactive Ion Beam Facility Design Study (EURISOL-DS) [1] for the WTF (Windowless Transverse Film) mercury converter. A preliminary study was carried out in order to determine the heat deposition within the mercury and estimate the mercury velocity needed in the film. The geometry used is based on previous analysis simulated using the Monte Carlo code FLUKA [2]. The results of these calculations show the baseline parameters, which will be used for the detailed design. Particularly, with a 1 GeV proton beam with a ~2 mm Gaussian distribution on a 4x30x40cm long target and with a 5m/s velocity at the peak power density region seems a suitable solution.

  16. X-ray emission reduction and photon dose lowering by energy loss of fast electrons induced by return current during the interaction of a short-pulse high-intensity laser on a metal solid target

    2018-04-01

    During the interaction of a short-pulse high-intensity laser with the preplasma produced by the pulse's pedestal in front of a high-Z metal solid target, high-energy electrons are produced, which in turn create an X-ray source by interacting with the atoms of the converter target. The current brought by the hot electrons is almost completely neutralized by a return current j → driven by the background electrons of the conductive target, and the force exerted on the hot electrons by the electric field E → which induces Ohmic heating j → .E → , produced by the background electrons, reduces the energy of the hot electrons and thus lowers the X-ray emission and photon dose. This effect is analyzed here by means of a simple 1-D temperature model which contains the most significant terms of the relativistic Fokker-Planck equation with electron multiple scattering, and the energy equations of ions, hot, and cold electrons are then solved numerically. This Ohmic heating energy loss fraction τOh is introduced as a corrective term in an improved photon dose model. For instance, for a ps laser pulse with 10 μm spot size, the dose obtained with a tantalum target is reduced by less than about 10% to 40% by the Ohmic heating, depending upon the plasma scale length, target thickness, laser parameters, and in particular its spot size. The laser and plasma parameters may be optimized to limit the effect of Ohmic heating, for instance at a small plasma scale length or small laser spot size. Conversely, others regimes not suitable for dose production are identified. For instance, the resistive heating is enhanced in a foam target or at a long plasma scale length and high laser spot size and intensity, as the mean emission angle θ0 of the incident hot electron bunch given by the ponderomotive force is small; thus, the dose produced by a laser interacting in a gas jet may be inhibited under these circumstances. The resistive heating may also be maximized in order to reduce

    Assessing lifetime prevalence of illegal substance use and accessibility to such substances. Determining risk factors and the protective factors linked to them. This was a cross-sectional study using descriptive and bivariate analysis. A survey was applied to 1,515 students from 8th to 11th grades in the city's schools, ages ranging from 12 to 18. An increase in lifetime prevalence and lower age for consumption onset were found. The main risk factors were determined to be academic environment and attitudes towards school authorities, linked to recreational and sports groups without control by elders, gang membership and engaging in risky and dangerous activities. The results showed the need for a critical review of current promotion and prevention strategies aimed at controlling the use of psychoactive substances amongst children and adolescents, according to the current reality of trafficking and domestic consumption in Colombia.

  19. Deforestation in the Amazon: What is illegal and what is not?

    Full Text Available Abstract Brazil has succeeded in reducing deforestation rates in the Amazon, but has not succeeded in explaining to the general public how much of this deforestation was illegal and how much was legally authorized. Transparency of deforestation data is limited, and pertinent legislation is little understood and poorly applied in practice. Lack of dissemination of information on authorized clearing of vegetation and lack of implementation of regulatory frameworks are contentious issues when defining strategies to reach zero deforestation in the Amazon region and for building policies related to climate change mitigation. The need to establish the new Forest Code provides an opportunity to establish goals and regulations for zero deforestation. This paper provides recommendations on how to communicate this information to the general public, how to make regulatory instruments effective and how to implement a zero deforestation agenda.

    A 14-year-old boy presented with low-grade fever, widespread myalgia and difficulty in walking and standing 2 days after the undocumented trip which brought him from western Africa to Italy. His serum creatine phosphokinase was markedly elevated. He was diagnosed with rhabdomyolysis and was volume-restored with normal saline and bicarbonate-containing fluid. Anamnesis revealed illegal, not well-specified, forced consumption in his fatherland, and very bad conditions of the trip (prolonged immobility, dehydration, hypothermia). Workup included a respiratory microbiological panel which was positive for Chlamydia pneumoniae Other microbiological agents were excluded. After 3 weeks, he recovered complete motility. Undocumented immigrants may present several risk factors for rhabdomyolysis that give to this group of individuals a higher risk of developing this disorder. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.
