The flow of foreign direct investment into developing countries varies greatly across countries and over time. The political factors that affect these flows are not well understood. Focusing on the relationship between trade and investment, we argue that international trade agreements—GATT/WTO and preferential trade agreements (PTAs)—provide mechanisms for making commitments to foreign investors about the treatment of their assets, thus reassuring investors and increasing investment. These international commitments are more credible than domestic policy choices, because reneging on them is more costly. Statistical analyses for 122 developing countries from 1970 to 2000 support this argument. Developing countries that belong to the WTO and participate in more PTAs experience greater FDI inflows than otherwise, controlling for many factors including domestic policy preferences and taking into account possible endogeneity. Joining international trade agreements allows developing countries to attract more FDI and thus increase economic growth.  相似文献

EU update     
This is the latest edition of Baker &; McKenzie's column on developments in EU law relating to IP, IT and telecommunications. This article summarises recent developments that are considered important for practitioners, students and academics in a wide range of information technology, e-commerce, telecommunications and intellectual property areas. It cannot be exhaustive but intends to address the important points. This is a hard copy reference guide, but links to outside web sites are included where possible. No responsibility is assumed for the accuracy of information contained in these links.  相似文献

This paper explores the link between increasing incidents of hate crime and the asylum policy of successive British governments with its central emphasis on deterrence. The constant problematisation of asylum seekers in the media and political discourse ensures that ‘anti-immigrant’ prejudice becomes mainstreamed as a common-sense response. The victims are not only the asylum seekers hoping for a better life but democratic society itself with its inherent values of pluralism and tolerance debased and destabilised.  相似文献

Mitochondrial DNA (mtDNA) analysis of forensic samples typically is performed when the quantity and quality of DNA are insufficient for nuclear DNA analysis or when maternal relatives may be the only reference source. Many of the steps required in the analytical process are both lengthy and labor intensive. Therefore, improvements in the process that reduce labor without compromising the quality of the data are desirable. The current procedure requires purification of the amplicons by centrifugal filtration after PCR and prior to cycle sequencing. Because this method requires several manipulations to perform, alternate cleanup procedures were investigated. These include the use of 1) Qiagen QlAquick PCR Purification columns, 2) Concert Rapid PCR Purification columns, and 3) ExoSAP-IT reagent. When the yield of purified amplicons, quality of the sequence profile, and ease of assay were evaluated, the use of ExoSAP-IT reagent for post-amplification purification was chosen to replace the filtration method.  相似文献

Physical restraint of people experiencing mental health problems is a coercive and traumatic procedure which is only legally permitted if it is proportionate to the risk presented. This study sought to examine the decision-making processes used by mental health staff involved in a series of restraint episodes in an acute care setting. Thirty nurses were interviewed either individually or in focus groups to elicit their views on restraint and experience in specific incidents. Four factors which influenced the decision to restrain were identified: contextual demands; lack of alternatives; the escalatory effects of restraint itself; and perceptions of risk. While some of these factors are amenable to change through improvements in practice, training and organisational culture, nurses viewed restraint as a necessary evil, justified on the basis of the unpredictable nature of mental illness and the environment in which they worked.  相似文献

A range of protein stains were utilised for the enhancement of footwear impressions on a variety of fabric types of different colours with blood as a contaminant. A semi-automated stamping device was used to deliver test impressions at a set force to minimise the variability between impressions; multiple impressions were produced and enhanced by each reagent to determine the repeatability of the enhancement. Results indicated that while most protein stains used in this study successfully enhanced impressions in blood on light coloured fabrics, background staining caused interference on natural fabrics. Enhancement on dark coloured fabrics was only achieved using fluorescent protein stains, as non-fluorescent protein stains provided poor contrast.A further comparison was performed with commercially available protein staining solutions and solutions prepared within the laboratory from the appropriate chemicals. Both solutions performed equally well, though it is recommended to use freshly prepared solutions whenever possible.  相似文献

Actuarial risk assessment instruments for sexual offenders are often used in high-stakes decision making and therefore should be subject to stringent reliability and validity testing. Furthermore, those involved in the risk assessment of sexual offenders should be aware of the factors that may affect the reliability of these instruments. The present study examined the interrater reliability of the Risk Matrix 2000/s between one field rater and one independent rater with a sample of more than 100 sexual offenders. The results indicated good interrater reliability of the tool, although reliability varies from item to item. A number of factors were identified that seem to reduce the reliability of scoring. The present findings are strengthened by examining interrater reliability of the tool in the usual practitioner context and by calculating a range of reliability statistics. Strategies are suggested to increase reliability in the use of actuarial tools in routine practice.  相似文献

Under the Human Rights Act so far there has been until very recently little judicial or even academic recognition of the difference between resolving clashes of Convention rights and addressing conflicts between utilitarian concerns and such rights. This article has chosen to illustrate that failure of recognition and to consider methods of resolving the conflict between rights, by concentrating on one particular clash of rights – that between media free speech under Article 10 and the privacy of children under Article 8. It argues for presumptive equality for the two rights and for conducting a 'parallel analysis' of their application to the circumstances of a particular case. It contends that therefore the principle that the child's welfare is paramount must be abandoned in its present form, as must the presumptive priority accorded to Article 10 where that principle is not found to apply.  相似文献

The relationships between childhood sexual abuse, social anxiety, and symptoms of posttraumatic stress disorder were examined in a sample of 313 undergraduate women. Thirty-one percent of the women reported some form of sexual abuse in childhood. Women with a history of sexual abuse reported more symptoms of anxiety, distress in social situations, and posttraumatic stress disorder than other women. Women who experienced attempted or actual intercourse reported more avoidance than women with no history of abuse and women with exposure only, and more PTSD symptoms than all other groups of women. Women who experienced fondling reported more PTSD symptoms than women with no history of abuse. Pressure, age of onset of abuse, abuse by a family friend, and abuse by other perpetrators were all significant abuse characteristics in predicting adult social anxiety. Implications of these results for research and interventions are discussed.  相似文献
