Gas chromatography was used to study the cannabinoid content ("potency") of illicit cannabis seized by police in England in 2004/5. Of the four hundred and fifty two samples, indoor-grown unpollinated female cannabis ("sinsemilla") was the most frequent form, followed by resin (hashish) and imported outdoor-grown herbal cannabis (marijuana). The content of the psychoactive cannabinoid delta 9-tetrahydrocannabinol (THC) varied widely. The median THC content of herbal cannabis and resin was 2.1% and 3.5%, respectively. The median 13.9% THC content of sinsemilla was significantly higher than that recorded in the UK in 1996/8. In sinsemilla and imported herbal cannabis, the content of the antipsychotic cannabinoid cannabidiol (CBD) was extremely low. In resin, however, the average CBD content exceeded that of THC, and the relative proportions of the two cannabinoids varied widely between samples. The increases in average THC content and relative popularity of sinsemilla cannabis, combined with the absence of the anti-psychotic cannabinoid CBD, suggest that the current trends in cannabis use pose an increasing risk to those users susceptible to the harmful psychological effects associated with high doses of THC.  相似文献

ABSTRACT

Since 2011, Myanmar has undertaken a series of domestic and foreign policy reforms, including democratisation and peacebuilding, before and after the watershed November 2015 elections in the country. These reform processes have called into question whether China, which has been Myanmar's dominant great power neighbour throughout the previous era of military government in the country formerly known as Burma, would find its strategic position eroding as Myanmar further opens to the international community. However, the concept of China ‘losing’ diplomatic ground to other actors, including the West, in Myanmar implies a zero-sum game that does not adequately address Beijing's still-formidable geostrategic presence vis-à-vis its southern neighbour. China has now started to implement a more multi-faceted, ‘resilience network’-building approach to maintaining its special status in Myanmar's foreign policy, a situation which will persist as Myanmar continues its uncertain path towards further reform.  相似文献

How does America's high rate of incarceration shape political participation? Few studies have examined the direct effects of incarceration on patterns of political engagement. Answering this question is particularly relevant for the 93% of formerly incarcerated individuals who are eligible to vote. Drawing on new administrative data from Connecticut, we present evidence from a field experiment showing that a simple informational outreach campaign to released felons can recover a large proportion of the reduction in participation observed following incarceration. The treatment effect estimates imply that efforts to reintegrate released felons into the political process can substantially reduce the participatory consequences of incarceration.  相似文献

Considerable ambiguity exists regarding the effect of government/opposition status on party platform change. Existing theories predict that (1) it has no effect, (2) opposition parties change more, (3) opposition parties change more after several spells in opposition, and (4) parties’ responses vary because of different goal orientations. We propose that a party's aspiration to office, measured by its historical success or failure in entering office, determines a party's reaction to being in opposition or government. We hypothesize that, because of loss aversion, parties with low office aspiration change more when they are in government than when they are in opposition. Conversely, parties with high office aspiration change more as opposition party than as government party. We find evidence for these hypotheses through a pooled time‐series cross‐sectional analysis of 1,686 platform changes in 21 democracies, using the Comparative Manifesto Data and an innovative measure of party platform change.  相似文献

This article considers barriers and strategies for implementing performance budgeting in real-time application by a state-level government. The lessons learned from the State of New Jersey’s implementation of the Governor’s Performance Budgeting Initiative offer guidelines for public and nonprofit sector organizations attempting similar efforts. Data was gathered through a series of focus groups with key executive-level administrators. Observations and recommendations for enhancing and reenergizing current performance budgeting strategies for a state or agency are suggested.  相似文献

International student enrollment in public service degrees such as Public Administration in the United States has grown rapidly. Harnessing this growth to improve the knowledge and expertise of employees in public service is a vital opportunity. However, our survey of public service schools shows that international students perceive an extensive lack of support with financial and linguistic challenges. Furthermore, schools practice little performance evaluation concerning international student experience. We conclude that schools collect more data on international students and communicate better information about programs to improve services and ensure that students know accurately what to expect from their overseas education.  相似文献

Abstract

This article challenges the claim, along with the statistics that support it, that self-employment is by far the dominant employment status in the informal economy. The article begins by reviewing key insights from relevant literature on the informal economy to argue that conventional notions of ‘wage employment’ and ‘self-employment’, while unfit for capturing the nature and variety of employment relations in developing countries, remain central to the design of surveys on the workforce therein. After putting statistics on Tanzania’s informal economy and labour force into context, the analysis reviews the type of wage employment relationships that can be found in one instance of the informal economy in urban Tanzania. The categories and terms used by workers to describe their employment situation are then contrasted with those used by the latest labour force survey in Tanzania. The article scrutinises how key employment categories have been translated from English into Swahili, how the translation biases respondents’ answers towards the term ‘self-employment’, and how this, in turn, leads to the statistical invisibility of wage labour in the informal economy. The article also looks at the consequences of this ‘statistical tragedy’ and at the dangers of conflating varied forms of employment, including wage labour, that differ markedly in their modes of operation and growth potential. Attention is also paid to the trade-offs faced by policy-makers in designing better labour force surveys.  相似文献

This article examines how political scientists in West Germany (1949–1989) dealt with public finance issues. Facing the enormous challenges of establishing a democracy and coming to terms with the legacy of National Socialism, it shows that neither tax nor budget policy played much of a role in this fledgling discipline during the first two decades of this country’s history. This was changing during the 1970s with the emergence of the largely neo-Marxist influenced debates about the nature of the state, when attention turned toward its finances. The resulting scholarly works argued primarily at the meta-level, however. It was not until the 1980s that researchers produced their first empirically sound, international comparative studies, focusing above all on budget policy.  相似文献

This article analyses divergent patterns of responses using survey data from rural households in three region of Russia. The purpose of this article is to explore how household responses to reform differ in geographically distinct regions. Second, the goal is to compare regional response patterns using a standardized set of reform dimensions: perceptions about winners and losers, responses to land reform opportunities, the structure of household income, and the use of economic assistance networks. The article concludes that factors other than geography and climate influence responses to reform.  相似文献
