In a decentralized welfare state, central and local governments need each other to settle refugees. Using the case of Norway, the article studies how these interdependencies have been governed over time, including through the 2015–2016 refugee crisis. Norway's refugee settlement programme is a conscious hybrid of market and network governance and it has remained essentially stable for more than 20 years, despite several changes in government, large fluctuations in the number of refugees, and long periods of poor performance vis-à-vis settlement targets. This surprising programme stability is explained by a combination of extraordinary political adherence to the democratic value of local government autonomy, the cupidity of local governments, and abundant state economic resources during the period under study.  相似文献

A crucial challenge for the coordination of horizontal policy programs—those designed to tackle crosscutting issues—is how to motivate government organizations to contribute to such programs. Hence, it is crucial to study how practitioners in implementing organizations view and appreciate the coordination of such programs. Assisted by Q-methodology, this inductive study reveals three significantly different “images”: central frame setting, networking via boundary spanners, and coordination beyond window dressing. Most surprisingly, different images show up among respondents within the same organizations and horizontal programs. The authors find that the images reflect elements of the literature: the resistance to hierarchical central control, the need for local differentiation and increased incentives, and a collaboration-oriented culture. Most importantly, practitioners of implementing organizations perceive top-down mechanisms as ineffective to achieve coordination and ask for adaptive arrangements, involvement, and deliberative processes when designing coordination arrangements and during the collaboration.  相似文献

The present investigation is an extension of an earlier work on the effect of various temperatures on Y-chromosome detection. The deteriorating effect of storage at 53 °C was again demonstrated. Liquid blood samples stored at 5 °C were better preserved with regard to Y-chromosomes than those stored at room temperature. This was in conflict with the earlier results on blood stains. New experiments were therefore performed. The results varied. It is suggested that this variation was due to low temperatures having two contrary effects on the results: the well-known preserving effect on biological material and a previously described constricting effect on the heterochromatic areas of the chromosomes making Y-body detection more difficult.  相似文献

This work is part of a larger investigation aiming at tracing differences between injuries caused by heat and electricity. Electrodes and heaters similar to the electrodes of an electric cattle baton are used to dissipate approximately 40 joules in 40 seconds in pig skin.Voltages in the range 40–60 volts (AC or DC) are applied via stainless steel electrodes and temperatures in the range 50–100 °C are applied via heaters made of copper wire. Heat transfer is controlled by electronically regulated heaters utilizing the temperature dependence of the heater wire itself as a thermometer.Transfer of electricity takes place from either commerical DC supply, from transformed voltage from the mains or from a sine voltage generator connected to a power amplifier. The energy transfer is in all cases measured by electronic integration of the dissipated power in time. The power supplied to the electrodes or the heaters is found by electronic multiplication of the applied voltage and current.Typical power vs. time curves are presented.  相似文献

Previously, electrical injuries have been suggested caused only by the concomitant heat developed during the passage of an electrical current. Recent experimental studies on fully anesthetized pigs and the study of one human case have, however, shown typical electrical alterations. The purpose of the present study was further to evaluate the histology of electrically induced changes in the skin in humans. In addition, supplementary in vivo methods for evaluation of skin changes as high-frequency ultrasound and Raman spectroscopy were used. The skin of 11 patients treated with a defibrillation of the heart was examined for macroscopic changes, the skin of eight of them also for histologic changes and for changes observable via supplementary methods. Immediately and 7 days after the defibrillation, fractions of a narrow red ring were observed along the periphery of the tin-foil electrode. Epidermis showed signs previously observed following electrical influence: segmental alterations often related to the openings of sweat ducts, darkstaining or "empty" nuclei and homogeneous cytoplasm, eosinophilic or pale. Dermis did not show the specific sign of electrical influence: deposits of calcium salts on dermal fibres, neither via histologic examination nor via high-frequency ultrasonography and Raman spectroscopy. Fractions of a narrow red ring along the periphery of the electrode showing histological signs of electric influence in epidermis thus appear to be characteristic of high voltage electrical injury.  相似文献

The impact of national politics on local county and municipal elections since about 1970 is studied at the aggregate national level in Denmark, Norway and Sweden. At this level, the local politics swing, i.e., the change in party support from one local election to the next, can to a high degree be predicted by the swing in national politics support. In Sweden, the national politics support is simply the party support at the national election held on the same day as the local elections, while opinion polls are used for Denmark and Norway. With the swing model for proportional impact from national to local politics, it appears that the national impact is stronger in Norway and Sweden than in Denmark. The swing model can be improved by including feedback from the difference between local politics and national politics support at the previous election. The feedback force from national to local politics estimated by the feedback model is also stronger in Norway and Sweden than in Denmark. Further, a preliminary analysis of Danish data indicates that the feedback model is especially relevant for analysis of data from the individual municipalities.  相似文献

Ecological inference has a long-standing tradition in political science. It addresses itself to the same substantive questions that provide the rationale for one election survey after another: estimating the floating vote and the party preferences of the social classes without the benefit of individual level data. The transition propensities and the party preferences are estimated or inferred from the aggregate-level ecological data provided by the official statistical production.  相似文献

Cannabinoids in blood and urine after passive inhalation of Cannabis smoke   总被引:1,自引:0,他引:1  
To test the possibility that cannabinoids are detectable following passive inhalation of Cannabis smoke the following study was performed. Five healthy volunteers who had previously never used Cannabis, passively inhaled Cannabis smoke for 30 min. Cannabis smoke was provided by other subjects smoking either marijuana or hashish cigarettes in a small closed car, containing approximately 1650 L of air. delta 9-Tetrahydrocannabinol (THC) could be detected in the blood of all passive smokers immediately after exposure in concentrations ranging from 1.3 to 6.3 ng/mL. At the same time total blood cannabinoid levels (assayed by radioimmunoassay [RIA] ) were higher than 13 ng/mL in four of the volunteers. Both THC and cannabinoid blood concentrations fell close to the cutoff limits of the respective assays during the following 2 h. Passive inhalation also resulted in the detection of cannabinoids in the urine by RIA and enzyme multiple immunoassay technique (EMIT) assays (above 13 and 20 ng/mL, respectively). It is concluded that the demonstration of cannabinoids in blood or urine is no unequivocal proof of active Cannabis smoking.  相似文献

With conventional staining techniques it was nearly impossible to differentiate with certainty between early ischemic myocardial lesions, autolytic changes and intact myocardium without a nuclear section. In 1986 it was introduced an immunohistochemical method, which presented C5b-9 Complement Complex as a necrosis marker in cryostat sections. Our further development of this process has resulted in a technique for application on routine paraffin sections: C5b-9 Complement Complex is particularly well-suited for the exact and autolytically insensitive presentation of disseminated necroses of fiber bundels and single fibers of myocardium. The application of the technique on paraffin sections will lead to the use of the same in forensic medicine routine diagnostics of early ischemic myocardial lesions, even in cases of "sudden" cardiac death.  相似文献
