This paper deals with civil society mobilizations and resistance in relation to a world heritage site—the ninth-century Khmer temple Preah Vihear, which is located in the northern province of Cambodia and borders eastern Thailand. In particular, the paper explores resistance in terms of (re)categorizations from a historical and discursive–materialistic perspective. The field of resistance studies has mainly been preoccupied with entities such as texts, signs, symbols, identity, and language. In this article, however, we bring in physical and material entities in order to display the ways in which matter is of importance in the (re)construction of discourses and thereby for resistance.  相似文献

This article is the first to statistically examine the reciprocal relationship between formal political institutions and political corruption. We argue that political corruption is an informal institution that allows nondemocratic leaders to build political support, act as a substitute for liberalizing concessions in the formal institutions of the state, and thereby extends the longevity of non-democratic regimes. Yet, whereas high corruption level will prevail in nondemocratic regimes, we expect the electoral constituency in democratic regimes to have the formal power to curb political corruption. We demonstrate that these expectations hold by estimating a dynamic multinomial regression model on data for 133 countries for the 1985–2008 period. Our model shows that high-corruption autocracies and hybrid regimes are more stable than their low-corruption counterparts, but that low-corruption democracies are more stable than high-corruption ones. For autocratic and hybrid regimes, the stability is due both to corruption making the formal institutions more resistant to democratization and that the formal institutions prevent reductions in corruption. Consistent democracies, on the other hand, are able to reduce corruption and become more stable as a result.  相似文献

Previous research has shown a consistent positive association between non-suicidal self-injury and depressive symptoms. However, the direction of the effects has not been examined. To understand whether non-suicidal self-injury predicts depressive symptoms or vice versa, we examined the relations between non-suicidal self-injury and depressive symptoms across three waves of self-report data collected 1 year apart from 506 Swedish adolescents (47 % girls; M age = 13.21; SD = .57) who were attending 7th grade at the onset of the study. The results suggest that depressive symptoms predict increases in non-suicidal self-injury 1 year later between the first and second waves of the study. Between the second and third waves of the study depressive symptoms and non-suicidal self-injury were significantly correlated indicating co-occurrence with no direction of effect rather than depressive symptoms predicting non-suicidal self-injury or vice versa. Group comparisons revealed no differences for boys and girls. The findings help clarify the relationships between non-suicidal self-injury and depressive symptoms during middle adolescence.  相似文献

Strikes are more common in those OECD countries where the legislature is elected in single member districts (SMD) than in those where it is elected by proportional representation (PR). Furthermore, more working days are lost due to industrial conflict in countries with SMD. I suggest a politico-economic explanation for these rarely noticed empirical regularities. Further empirical testing – including controls drawn from previous strike research – reveals that they hold up in a variety of econometric specifications.  相似文献

A 6-year longitudinal panel study investigated the absolute and relative stability in depressed mood throughout adolescence by reporting data from a sample of 538 adolescents between 13 and 19 years of age. Results revealed the following. (1) Girls had on average higher depressed mood scores than boys at all ages. (2) Among boys there were no substantial changes in depressed mood mean scores, while among girls there was a slight tendency of a curvilinear trend, with a peak level reached in midadolescence. (3) There was a tendency for adolescents to retain their relative level in depressed mood, most pronounced for a period of 4 years, from age 15 to age 19 years. (4) Depressed mood was most stable in a subgroup of adolescents who had high initial depressed mood scores. (5) By applying structural equation modeling, it was shown that the stable (trait) component of depressed mood increased in importance with increasing age, while the temporal (state) component decreased with increased age.  相似文献

This paper describes an effort to develop a clinical tool for the continuous monitoring of risk for violence in forensic mental health clients who have left their institutions and who are dwelling in the community on a conditional release basis. The model is called Structured Outcome Assessment and Community Risk Monitoring (SORM). The SORM consists of 30 dynamic factors and each factor in SORM is assessed in two ways: The current absence, presence or partial och intermittent presence of the factors, which is an actuarial (systematized and 'objective') assessment. Secondly, the risk effect, i.e. whether the presence/absence of factors currently increases, decreases or is perceived as unrelated to violence risk, is a clinical (or impressionistic) assessment. Thus, the factors considered via the SORM can be coded as risk factors or protective factors (or as factors unimportant to risk of violence) depending on circumstances that apply in the individual case. Further, the SORM has a built-in module for gathering idiographical information about risk-affecting contextual factors. The use of the SORM and its potential as a risk monitoring instrument is illustrated via preliminary data and case vignettes from an ongoing multicenter project. In this research project, patients leaving any of the 9 participating forensic hospitals in Sweden is assessed at release on a variety of static background factors, and the SORM is then administered every 30 days for 2 years.  相似文献

A simple procedure based on a common silica gel column chromatography for the isolation of Delta9-tetrahydrocannabinolic acid A (Delta9-THCA-A) from hemp in a multi-milligram scale is presented. Further, the decarboxylation reaction of Delta9-THCA-A to the toxicologically active Delta9-tetrahydrocannabinol (Delta9-THC) at different analytical and under-smoking conditions is investigated. Maximal conversion in an optimised analytical equipment yields about 70% Delta9-THC. In the simulation of the smoking process, only about 30 % of the spiked substance could be recovered as Delta9-THC.  相似文献
