Since Vietnam introduced its Doi Moi reform policy in 1986, the development of the private sector has been a main policy concern for the government and the ruling Communist Party. The main development challenge for Vietnam is how to sustain economic growth and reduce poverty as the labour force continues to expand. It is envisaged that the private sector will play a major role in that respect. This article looks into the issue of whether the private sector can live up to widespread expectations. High and stable economic growth indicates that reforms have been consistent but also that private-sector initiatives have moved ahead of formal institutional changes. Private-sector development is new in Vietnam and starts from a low level. The public and foreign investment sectors are major players compared to the domestic private sector, which comprises many small firms. Poverty reduction has been impressive but it is only now that private-sector development is becoming an important contributor. Stemming the growth in inequality remains a challenge where the private sector's contribution to increasing public revenue has yet to materialise.  相似文献

International measures to address environmental problems increasingly rely on scientific information, and a growing number of international agreements require periodic scientific re-assessments. However, the arena of scientific assessment, governed by a combination of scientific criteria and political interests, is not well-understood, and few case studies have mapped the influence of scientific assessment on the birth and development of environmental policy issues. This article examines the role of scientific assessments and the science-politics interplay in international attempts to regulate persistent organic pollutants (POPs), focusing on the processes within the Convention on Long-Range Transboundary Air Pollution (CLRTAP) and the United Nations Environment Programme (UNEP). The study shows that scientific and political activities are intrinsically linked in international POPs work. Scientific and political agendas are co-constructed with no clear boundary between the science and politics spheres. Scientific assessments played a prominent role in constructing POPs as an issue of international concern, setting agendas and shaping policies.  相似文献

This article provides a background for the Developing post-2012 scenarios project, an international study which looks at a range of scenarios that countries may wish to consider for a post-2012 framework to tackle climate change. The purpose of the article is threefold. Firstly, it provides a review of the literature for the future climate regime. Secondly, it provides a set of criteria that are used in order to evaluate whether the scenarios provided in the other articles in this Special Edition are likely to be effective. Thirdly, the article spells out some of the more general policy implications rising from these scenarios.  相似文献

Extended blood loss results in several compensatory physiological mechanisms, including transfer of extravascular fluid into the blood circulation. If drugs are present in the body, this fluid exchange may imply that blood drug concentrations found in a trauma victim may differ from the concentrations present at the time of the trauma. To address this issue, an animal model was used to investigate the influence of blood loss on pre-existing levels of the antidepressant drug citalopram and its demethylated metabolites. Rats were administered citalopram either acutely (40 mg/kg, orally) or chronically (20 mg/kg daily, subcutaneously) for 6 days using osmotic pumps. In the experimental rats, blood loss was accomplished by withdrawing 0.8 mL blood at 10 min intervals during 70 min. In the control rats, blood was withdrawn at 0 and 70 min only. Blood, brain and lung drug concentrations were analyzed with an enantioselective HPLC method. In the chronically treated rats, the ratios between final and initial citalopram concentrations were 1.08 +/- 0.15 and 1.01 +/- 0.09 in the experimental rats and controls, respectively, indicating no major effect of blood loss. In contrast, acute oral administration resulted in increased ratios in the exsanguinated rats as compared to controls (1.84 +/- 0.50 versus 0.73 +/- 0.07; p = 0.0495). In conclusion, the observation of increased blood drug levels in the acute oral rats indicates that absorption of fluid from the gastrointestinal tract may be important in the intravascular refill. Further, in the interpretation of post-mortem blood levels of drugs, these physiological mechanisms should be taken into account.  相似文献

When states in northern Nigeria started processes for implementing Sharia laws in 1999, it triggered sentiments all over the country. In Kaduna State, the proposal led to demonstrations and violent clashes. The article examines the ways in which different scales of politics are mutually constituted in the Sharia case and how the Sharia proposal subsequently resulted in clashes in Kaduna. It is argued that the Sharia initiative, even though it started as a sub-national question, was connected to a national power contestation. However, the federal government remained passive and diverted the issue to local political space. In Kaduna, the issue took dimensions that incurred with apprehensive local political contention that made it escalate into violence and polarising people according to religion. An analysis of the crisis in Kaduna is offered that does not regard the conflict as locally confined, but as inherently related to wider political and historical processes.  相似文献

In this article, results from self-report studies in two Finnish cities, Helsinki and Turku, are presented. The aims are to compare the prevalence of youth crime between these cities and changes in delinquency during the observation period. In Helsinki, the surveys took place in 1992, 2006 and 2013, and in Turku, the surveys took place in 1992, 2001, and 2013. With the exception of the Turku 2001 survey, all datasets have been collected under the auspices of the International Self-Report Delinquency Study (ISRD). The most recent survey, ISRD3, targeted comprehensive school pupils from grades 7–9 (ages 13–16), while some of the former studies excluded 7th and/or 8th grades. The results show that (1) the delinquency rates are generally higher in Helsinki than in Turku and (2) the prevalence of both property- and violence-related crimes has decreased, while drug use manifested fluctuating or increasing trends. Overall, the findings are consistent with the observation that there has been a relatively general crime drop in the Western world since the 1990s.  相似文献

This paper analyses whether direct government assistance during start-up and other forms of interaction with the state sector have influenced the long-run performance of small and medium-sized manufacturing enterprises (SMEs) in Vietnam. Using three partly overlapping surveys during the period 1990–2000, we find strong effects on firm dynamics from interaction with state institutions. Enterprises which have the state sector as their main customer perform better. This is so for both survival and growth. Moreover, temporary tax exemptions during firm start-up had a separate and positive influence on long-run growth for non-household enterprises and initial credit support seems to benefit rural firms.  相似文献

Abstract

The competition for energy resources, as well as the closely related climate change problems, imply a number of global security consequences. A methodology to include energy aspects in long-term defence planning, based on broad civilian scenario approaches, is proposed. The study has been carried out by the Swedish Defence Research Agency, as commissioned by the Swedish Armed Forces, resulting in a number of future mission scenarios highlighting e.g. new challanges and tasks, as well as the need for new capabilities and equipment.  相似文献

This paper on theft in Sweden analyses crime and reactions to crime in non-individual, structural terms. The data used stems from Swedish convictions statistics which are available for the period since 1831. Swedish trends in theft convictions follow an international pattern with reductions during the second half of the 19th century and settling at a comparatively low level during the decades around the turn of the 20th century. A sharp occurred after the mid-1920s until the mid-1980s. Upon closer examination, this increase took the form of an S-curve whose course resembles that of goods production. One interpretation is that once a basic level of material security had been guaranteed, theft convictions followed the availability of goods; with more to consume, there is more to steal, and levels of control tend to diminish. Howthat ever, this interpretation may not apply to a smaller proportion of convictions ? those which concern persistent offenders. Their development differed in one decisive manner from that of casual offenders ? the steep rise is very sudden and occurred first after the Second World War. An explanation based on the relationship between livelihood, excessive alcohol consumption and theft is put forward.  相似文献
