This paper provides an empirical investigation of the factors contributing to single-party dominance in Tanzania. Despite the fact that Tanzania has had a multi-party democracy since 1995, the party which governed during single-party rule, the Chama Cha Mapinduzi (CCM), has won the vast majority of seats in the National Assembly in the first four multi-party elections. In order to understand the CCM's grip on power, this article analyses the results of a survey conducted amongst subsistence farmers in Tanzania, which provides information on farmers’ livelihood conditions, access to media and political views, and hence provides insight into the preferences underlying voting behaviour. It discusses the dominant reasons for CCM support, as well as the characteristics of farmers who are more likely to support an opposition party. It concludes by discussing possible policy options for enhancing political competition in Tanzania.  相似文献

This paper examines the debate around the headscarf in France with the view to critically examining two central arguments put forward by the Stasi Commission for the restriction of the headscarf in French public schools—that the headscarf imperiled public order and that it jeopardized neutrality in the public sphere. In the case of the first argument, this paper argues that France did not meet the threshold requirement necessary to curtail religious rights in public schools. In the case of the second argument, this paper insists that neutrality in the pulic sphere has always involved some accommodation of religious groups in society and should include the headscarf in public schools. The paper argues that the decision to ban the headscarf is ultimately a controversy about French identity and the values on which the French community is built.  相似文献

Juveniles who are transferred to adult court are more likely to recidivate than non‐transferred juveniles, but limited research has examined how transfer can impact other life outcomes like attending college and employment. To examine this issue, data from the National Longitudinal Survey of Youth (1997) were analyzed from 1998 to 2011. It was found that court involvement during adolescence does not harm educational attainment. However, prosecution of juveniles in adult court significantly impairs earning potential well into adulthood. The current study provides further evidence of the long‐term harms caused by transfer and demonstrates how transfer further disrupts the desistance process.  相似文献

This study explored the molecular mechanisms potentially underlying blow fly nocturnal oviposition. A behavioral study revealed that Calliphora vicina (Robineau-Desvoidy) (Diptera: Calliphoridae) possesses a diel rhythm of oviposition in light under 12:12 light/dark conditions. Reversal to 12:12 dark/light resulted in oviposition behavior changing to align with the adjusted regime in most females, but four of 59 experimental females lacked a diel rhythm of oviposition (were arrhythmic). Real-time PCR was used to monitor the molecular expression levels of known circadian genes per and tim in C. vicina to determine whether gene expression and behavior correlated. As with behavior, reversing light/dark conditions changed rhythmic gene expression to align with an adjusted light regime. This suggests that although it is unlikely that C. vicina will colonize dead bodies at night, arrhythmic females and oviposition in the dark was demonstrated.  相似文献

The study investigates the impact of psychological well-being, coping style, and maltreatment types on adult partner maltreatment patterns. A large sample of undergraduates completed assessments measuring history of childhood violence exposure, psychological distress, coping, and adult partner maltreatment. The multiply abused group (childhood physical abuse and witnessing family violence) experienced the highest levels of all forms of adult maltreatment, followed by the childhood physical abuse group. As childhood victimization became more severe, the relationship between childhood victimization and adult partner maltreatment became more direct. The current study highlights that individuals exposed to a greater degree of childhood victimization are more vulnerable to adult maltreatment because there are few mediators which may prevent or decrease risk for adult maltreatment. The results suggest that treatment and prevention efforts with victims of interpersonal violence should foster individualized coping skills and address specific psychopathology depending upon the individual??s childhood abuse history.  相似文献

This paper expands on Archer (J Forensic Sci 49, 2004, 553), examining additional factors affecting ambient temperature correction of weather station data in forensic entomology. Sixteen hypothetical body discovery sites (BDSs) in Victoria and New South Wales (Australia), both in autumn and in summer, were compared to test whether the accuracy of correlation was affected by (i) length of correlation period; (ii) distance between BDS and weather station; and (iii) periodicity of ambient temperature measurements. The accuracy of correlations in data sets from real Victorian and NSW forensic entomology cases was also examined. Correlations increased weather data accuracy in all experiments, but significant differences in accuracy were found only between periodicity treatments. We found that a >5°C difference between average values of body in situ and correlation period weather station data was predictive of correlations that decreased the accuracy of ambient temperatures estimated using correlation. Practitioners should inspect their weather data sets for such differences.  相似文献

Cybercrime has become a growing national and international concern because of its potential for widespread and devastating financial impact. Gauging the effect of cybercrimes is extremely difficult because of its multi-faceted nature and evolving definitions, especially in cross-culture analyses. Using data generated from cybercrime reports from two leading national newspapers during the past ten years, this study compares major cybercrimes and law enforcement in China and the United States. Similarities and differences between the two nations are highlighted and policy implications are presented based on these findings.  相似文献

Gunshot Residue (GSR) produced by the discharge of a firearm often provides very useful information in criminal investigations in cases involving the use of firearms. Scanning Electron Microscopy equipped with an Energy Dispersive X-ray Spectrometer (SEM-EDS) is typically used worldwide to visualize micrometric particles constituting GSR and to analyse their elemental composition. The 2017 ASTM Standard guide for gunshot residue analysis by scanning electron microscopy/energy dispersive X-ray spectroscopy specifies that “Particles classified as characteristic of GSR will have one of the following elemental compositions: Lead, antimony, barium; Lead, barium, calcium, silicon, tin”. For the first time, the presence of an additional element, such as Sn, plays a key role in ASTM particle classification. It is known that some ammunitions, used for pistols, revolvers and rifles, contain tin foil discs for sealing the primer mixture into the cup, resulting in GSR particles containing Sn. The authors faced some cases in which Sn was unexpectedly found in GSR particles from a 0.22 Long Rifle derringer and from some 12 gauge shotguns. No tin foil discs are used in rimfire ammunitions and there is no published evidence of tin foil discs in shotshell ammunitions. Following a “case by case” approach, experimental research has been carried out to explain how Sn can be present in GSR particles when the last discharged cartridge also does not contain any Sn either in components and in the explosive charges.Moreover, the use of Particle Induced X-ray Emission (PIXE) showed the capability to overcome overlap ambiguity of Sb and Sn peaks in the X-ray spectra, being a possible key issue in real shooting cases if Sn quantities are below the lower limit of SEM detection, especially when Sb is also present.  相似文献
