Two challenges stand out in the study of deliberation: the development of appropriate methodological tools and the development of more unified analytical frameworks. On the one hand, analysing deliberative processes is demanding and time‐consuming; hence we tend to have only few and non‐randomly selected cases at the group or context level. In addition, the real world of deliberation presents us with a complex matrix of nested, cross‐classified, and repeated speakers. This article shows that Bayesian multi‐level modelling provides an elegant way to tackle these methodological problems. On the other hand, we attempt to enrich comparative institutionalism with individual characteristics and psychologically relevant variables (such as group composition). Focusing on Swiss and German parliamentary debates we show that institutional factors ‐ in particular, consensus systems ‐, the gender composition of committees and plenary sessions, and age matter for the quality of deliberation. Furthermore, we also show that partisan affiliation ‐ government or opposition status of MPs ‐ affects deliberative quality and can refine institutional arguments. We conclude that a multi‐level approach to deliberation focusing on contextual and actor‐related characteristics and using Bayesian hierarchical modelling paves the way toward a more advanced understanding ‐ and methodological handling ‐ of deliberative processes. 相似文献

The rise of the Internet has a profound impact on the way conflicts are carried out and the faithful practice their religions. This article explores new dimensions of religious conflicts by theoretically reflecting on new developments in cyberage and by substantiating this with an empirical case study—the Moluccan conflict (Eastern Indonesia). Due to the exponential growth of Internet access worldwide, religions and their followers are increasingly expanding into the online world as a new “marketplace” for religious symbols and identities that fosters religious transnationalism. At the same time conflict actors worldwide have been making increasing use of the Internet to expand their networks, plan actions and fight their enemies. While scholars have so far primarily focused on more globalized online terrorism, this paper analyses a conflict that has mainly been fought out between Christians and Muslims in a remote part of this world, but then expanded into cyberspace. Local conflict actors have used the Internet as a global stage for their cause, to connect to and seek support from their transnational religious communities, but also to manipulate the outside world's perception of the Moluccan conflict. Researching the online projects and identity politics of these actors and their offline contexts, it becomes clear that the Internet has helped to essentialize (religious) identities and to influence the conflict at the local level through the networking and mobilization of people worldwide. 相似文献

The dimensions of Type A behavior were studied in 990 randomly selected adolescents and their conceptualization was clarified in terms of achievement striving, self-concept, and sense of control. The methods used were the AFMS to evaluate Type A behavior, the Nowicki-Strickland Locus of Control Scale, and Coopersmith's Self-Esteem Inventory. Achievement striving was assessed using the questionnaire designed for this study. It was revealed that Type A consisted of two independent dimensions, both adding an equal contribution to the total score. One was an impatient, aggressive competitiveness related to a low self-esteem, low self-set achievement standards, and external locus of control. The other Type A exhibited competitiveness related to a sense of responsibility, leadership, social activity, high achievement striving, and high self-esteem. These factors may distinguish maladjusted competitiveness from healthy ambition and suggest that it is important to distinguish risk Type A individuals from Type A's who are potential leaders in society.Received Ph.D. in Psychology from the University of Helsinki, Finland.

Abstract In several recent studies George Rabinowitz and his co–authors challenge the 'classical' spatial model of issue voting, the proximity model, by introducing a directional model. In this article we examine whether different measurement of perceived issue positions of candidates or parties leads to diverging judgments about the predictive power of the directional model (which is claimed to be empirically superior), as compared to the proximity model, using data from the USA and Germany. The results demonstrate that the measurement preferred by Rabinowitz et al. tends to bias empirical findings in favour of directional theory. If we use a more plausible operational definition of issue positions of candidates and parties the directional model in both countries fails to turn out superior. 相似文献

Fentanyl is a very strong opioid with analgesic properties that are approximately 80 times stronger than those of morphine and therefore is used in major surgery and treatment of pain in tumor patients. Cases of fentanyl abuse by intravenous injection, inhalation, oral or nasal application have been reported especially in the USA. Therapeutic levels of fentanyl are as low as 1 ng/ml of serum and therefore a screening test must have a detection limit below that concentration. Recently three non-radioactive enzyme immunoassays (EIAs) have become commercially available from COZART, STC and DIAGNOSTIX, all of them supplied by MAHSAN Diagnostika for evaluation with serum samples from forensic and clinical cases. A calibration curve is obtained with samples that contain 0, 0.1, 0.5, 1 and 5 ng fentanyl per ml of negative serum. The calibration curve of COZART is especially in the low range, steeper than those of STC and DIAGNOSTIX. The cut-off for all these EIAs, however, can be set at 0.5 ng/ml. After the administration of therapeutic doses, fentanyl concentrations were between 3 and more than 5 ng/ml as determined with the EIAs. The presence of the typical drugs of abuse, e.g. heroin, methadone, cocaine, cannabinoids and amphetamines including the derivatives of methylenedioxyamphetamine, don't generate false-positive results. No cross-reactivity was also observed at toxic levels of benzodiazepines and paracetamol and therapeutic levels of barbiturates, phenothiazines, antidepressants and analgesics. The EIAs tested so far appear to be suitable for the detection of fentanyl at therapeutic levels. False-positive results or cross-reactivity towards other compounds have not been observed. 相似文献

3,4-methylenedioxyamphetamine (MDA) derivatives are increasingly abused central nervous system stimulants with neurotoxic properties. In recent years a number of controlled substance analogs (designer drugs) with high structural variety reached the illegal market making their identification an arduous task. The underivatized compounds give very similar or even virtually identical electron impact mass spectra containing mainly intense C(n)H(2n+2)N(+) immonium ions. Using tandem mass spectrometry (MS-MS) the additional structural information contained in the collision induced dissoziation (CID) mass spectra of molecular ions using electron impact (EI) and especially chemical ionization (CI) allowed an unequivocal differentiation of 18 studied regioisomeric 1-(methylenedioxyphenyl)-2-propanamines and 1-(methylenedioxyphenyl)-2-butanamines.Further synthetic methods are presented for 1-(3,4-methylenedioxyphenyl)-N-propyl-2-butanamine, N-isopropyl-1-(3,4-methylenedioxyphenyl)-2-butanamine and four 1-(2, 3-methylenedioxyphenyl)-2-butanamines. N-alkylated 1-(3, 4-methylenedioxyphenyl)-2-butanamine compounds (e.g. MBDB) are also known to be abused psychoactive agents (entactogenes) without the sympatomimetic effects of the 3,4-methylenedioxyamphetamines. 相似文献
