Previous research indicates the importance of interpersonal communication in the political socialization process. Investigations of political talk have mostly been restricted to frequency, and the theorizing of its effects centered on cognitive outcomes such as knowledge and ideological identification. This study examined the part played by private political talk in promoting expressive forms of political participation among adolescents. Recent survey panel data from Swedish 13–18-year-olds were analyzed. Results showed that frequency of private political talk predicted the extent of public political expression even when self-selection and previous levels of political expression were accounted for. Data offered some support for an expected interaction of private political talk and political interest in predicting public expression. The overall findings are consistent with the theoretical idea that political talk offers adolescents opportunities to enact participation in safe settings, and that this is a mechanism that can explain why talking about politics is favorable for political development during adolescence.  相似文献

A retrospective study was undertaken of all cases of death due to suicidal electrocution in Sydney, Australia between 1996 and 2005. A total of 25 cases were identified with 20 cases (80%) as a result of direct attachment to an electrical outlet and five cases (20%) as a result of immersion in a body of water with an electrical appliance. Twenty of the 25 individuals were men (mean age = 57 years, range 22-90) and five were women (mean age 67, range 53-88). At least 35% of decedents were either currently working or had worked as electricians. Electrical timers had been used in eight (32%) cases, the fuse blown in one case, but the remaining 16 (64%) bodies were "live" on arrival of witnesses or electricity personnel. This study demonstrates the phenomenon of electrical suicide as a regular occurrence in Sydney. We highlight the need for investigators and emergency workers to remain vigilant upon discovery of electrical suicides, due to the fact that most bodies remain electrically active after death.  相似文献

Although saliva or oral fluid “lacks the drama of blood, the sincerity of sweat and the emotional appeal of tears”, quoting Mandel in 1990 [I.D. Mandel, The diagnostic uses of saliva, J. Oral Pathol. Med. 19 (1990) 119–125], it is now meeting the demand for inexpensive, non-invasive and easy-to-use diagnostic aids for oral and systemic diseases, drug monitoring and detection of illicit use of drugs of abuse, including alcohol. As the salivary secretion is a reflex response controlled by both parasympathetic and sympathetic secretomotor nerves, it can be influenced by several stimuli. Moreover, patients taking medication which influences either the central nervous system or the peripheral nervous system, or medication which mimic the latter as a side effect, will have an altered salivary composition and salivary volume. Patients suffering from certain systemic diseases may present the same salivary alterations. The circadian rhythm determines both the volume of saliva that will and can be secreted and the salivary electrolyte concentrations. Dietary influences and the patient's age also have an impact on composition and volume of saliva. The latter implies a wide variation in composition both inter- and intra-individually. Sampling must therefore be performed under standardized conditions. The greatest advantage, when compared to blood sample collection, is that saliva is readily accessible and collectible. Consequently, it can be used in clinically difficult situations, such as in children, handicapped and anxious patients, where blood sampling could be a difficult act to perform.  相似文献

During the First World War, the Commission for Relief in Belgium (CRB) supplied occupied Belgium with food, provoking discord between military and political leaders on both sides. The CRB's work undermined the Allies' economic blockade of the enemy, attracting military criticism. In Germany, politicians favoured sustaining the food supply to prevent unrest, whilst the Army wanted to exploit Belgium's resources. From 1916 onwards, the CRB became a bone of contention in Germany in the dispute between military and political leaders about unrestricted submarine warfare. It also loomed large in the political and military debate about the attitude to neutral countries: the Allies wanted them to brave the German threat and cooperate with the blockade policy—otherwise, food imports from Allied countries would be forbidden. Tonnage and food for the CRB were incorporated into the negotiations with neutral countries about their imports and the use of home-grown produce. The debates about the CRB thus exemplify the relationship between military events and the war's economic and social significance. This study of the CRB shows that political/diplomatic historiography can bridge the gap between the military and socioeconomic history of the First World War.  相似文献

All cases of fatal oxycodone toxicity presenting to the New South Wales Department of Forensic Medicine over the period January 1, 1999, to December 31, 2008, were retrieved. A total of 70 cases were identified. The mean age was 48.9 years, 58.6% were men, 21.4% were suicides, and in 30% oxycodone had not been prescribed to the decedent. Injecting drug users constituted 27.1% of cases, and oxycodone tablets were injected immediately prior to death by 21.4%. The mean blood oxycodone concentration was 0.40 mg/L (range 0.06-53.00 mg/L). In all cases, psychoactive substances other than oxycodone were also detected, most frequently hypnosedatives (68.6%), other opioids (54.3%), antidepressants (41.4%), and alcohol (32.9%). Preexisting systemic disease was common: cardiovascular (64.2%), pulmonary (49.3%), hepatic (66.7%), and renal (43.9%).  相似文献

Abstract:  To determine the prevalence and circumstances of psychoactive substances amongst homicide victims, 485 consecutive cases autopsied at the NSW Department of Forensic Medicine (1/1/1996–12/31/2005) were analyzed. Substances were detected in 62.6% of cases, and illicit drugs in 32.8%. Alcohol, cannabis, opioids, and psychostimulants were most commonly detected. Alcohol and cannabis were both more prevalent amongst males. Mean ages were significantly younger for decedents who tested positive for a substance and for an illicit drug. Cases where death resulted from a physical altercation were more likely to have had alcohol and cannabis present. Illicit drugs were prominent amongst firearms deaths. The proportion of alcohol positive cases increased from 25.0% on Monday to 49.4% for Saturdays/Sundays. Alcohol was more common in incidents in the 0001–0600 h and 1800–2400 h periods. Psychoactive substances appear to substantially increase the risk of homicide, although there are important differences between drug classes in the circumstances of such incidents.  相似文献

Hair samples of patients of psychiatry and hair samples of suicide cases were analysed by liquid-chromatography/ionspray-mass spectrometry (LC/MS) for antidepressants and neuroleptics. Electrospray ionisation (ESI) with in-source collision induced dissociation (ESI/CID) and tandem-mass spectrometry (MS/MS) were used for drug and metabolite identification. Mass spectra library searching was performed using an ESI/CID mass spectra library and a MS/MS spectra library. Furthermore, extracted ion chromatograms were used for the detection of N-desmethyl-metabolites, which were also identified by their fragment-ion spectra. Three examples using these methods are shown: The tricyclic antidepressant maprotiline, the selective serotonin receptor inhibitor (SSRI) citalopram and their desmethylmetabolites as well as the neuroleptic pipamperone were detected and identified in hair extracts. For extraction powdered hair was treated by ultrasonication in methanol and solid-phase extraction was used for sample clean-up prior to LC/MS or MS/MS analysis. These examples demonstrate the power of LC/MS and LC/MS/MS for the detection and identification of drugs in hair extracts using full-scan mode and ESI/CID with library searching or using highly selective LC/MS/MS-analysis with library searching or in multiple reaction monitoring mode.  相似文献

In a series of experiments we show that people learn to playthe efficient outcome in an open-ended rent-seeking game. Thisresult persists despite quite different experimentenvironments and designs, like different propensities ofcompetition, group sizes etc., and is interpretable as aresolution of the so-called Tullock paradox which states thatreal-world rent-seeking expenditures are much lower than whatthe standard rent-seeking model predicts.  相似文献

The article focuses on new forms of governance involving partnerships between public and private actors. As several scholars have noticed, organisational hybrids at the intersection of the public and private sectors play an important part in the implementation of collective action. Local economic development in particular has provided a fertile ground for building coalitions across traditional divisions, and encouraging partnerships. This applies to Norway as well as to other liberal Western democracies.
Obviously, the formation of partnerships reflects efforts to design more efficient and flexible instruments for founding new firms and for supporting local entrepreneurs. The article, however, raises the question of whether these arrangements may entail a far more expanded role and domain, opening up new channels for participation and mobilisation. By expanding their agenda and integrating new segments of the local community, public–private partnerships appear to be an innovation in local democracy.
Analytically, the article utilises elements of regime theory. Although the partnerships studied hardly constitute stable coalitions dominating local politics, they nevertheless illustrate how the building of coalitions including both private and public actors is crucial to coping with the problems and challenges of local restructuring and revitalisation. Case studies carried out in Norwegian municipalities provide the main empirical source. The article does, however, build on experience from other European countries.  相似文献
