AbstractBuilding on studies on the political business cycle, the literature on welfare state retrenchment has argued that governments which cut the welfare state try to avoid blame by implementing painful measures in the beginning of the mandate and expanding benefits as elections approach. In contrast to this linear relationship, this article argues that governments often feel pressured to fulfil (mostly expansionary) campaign promises during the first months in office. Consequently, cutting right away is not what should be expected. Instead, a more nuanced, U-shaped timing trajectory is probable with a period in the beginning characterised by both cuts and fulfilment of expansionary pledges, followed by a period of cutbacks, and finally an expansive phase towards the end of a mandate. This argument is tested on our new original dataset of legislative changes in five European countries – Britain, Denmark, Finland, France and Germany – during the last four decades. 相似文献

Understanding the conflict between pro- and anti-Rhodesian government parliamentarians is the only way to understand how and why Australia struggled to formulate a coherent Rhodesia policy. It reveals the extent to which Malcolm Fraser had to struggle against his own party in this matter and adds needed nuance to this period. Fraser's opinion that Rhodesia was a racist and immoral project caused a schism in the Coalition parties. Despite Fraser's open antipathy towards Rhodesia, Rhodesia's interests in Australia were largely safeguarded. This reflects the reality that the Liberal and National Country Parties contained sizeable blocs of parliamentarians who openly and publicly saw Rhodesia as a fraternal country, not a dangerous pariah. They did not hold these beliefs passively and actively sought to resist any moves made by Fraser to damage Rhodesia and its interests. By following the development of Fraser's Rhodesia policy in the late 1970s the power of Rhodesia's allies in the Australian parliament becomes clear. Opposing Rhodesia was touted by Fraser as one of the greatest achievements of his government, yet the issue was divisive and caused bitter infighting. 相似文献

AbstractOne key marker of mass social movements transitioning to participatory democratic governance is popular media access. This essay argues that democratic media access by public constituencies becomes a site for constructing social revolution and simultaneously a manifest empirical measure of the extent of democratic participation in the production, distribution, and use of communication with new cultural possibilities. The participatory production practices (with citizens producing and hosting their own programs) and the democratic content (of oral histories, local issues, critiques of government and business, and everyday vernacular) reflect the hegemony of emerging ‘Bolivarian’ twenty-first century socialism expressed as popular participation in media production. Bolstered by constitutional changes and public funding, popular social movements of civil society, indigenous, women, and working class organizations have gained revolutionary ground by securing in practice the right of media production. Findings indicate that public and community media (that move beyond alternative sites of local expression and concerns) provide a startling revolutionary contrast to the commercial media operations in every nation. Popular media constructions suggest a new radically democratic cultural hegemony based on human solidarity with collective, participatory decision-making and cooperation offering real possibilities and experiences for increased equality and social justice. 相似文献

Network-attached storage (NAS) is a system that uses a redundant array of disks (RAID) to create virtual disks comprising multiple disks and provide network services such as FTP, SSH, and WebDAV. Using these services, the NAS's virtual disks store data about individuals or groups, making them a critical analysis target for digital forensics. Well-known storage manufacturers like Seagate, Synology, and NETGEAR use Linux-based software RAID, and they usually support Berkeley RAID (e.g., RAID 0, 1, 5, 6, and 10) as well as self-developed hybrid RAID. Those manufacturers have published data on the introduction and features of hybrid RAID, but there is not enough information to reassemble RAID from a digital forensic perspective. Besides, digital forensic tools (such as EnCase, FTK, X-ways, and RAID Reconstructor) do not support automatic RAID reassembly for hybrid RAID, so research on hybrid RAID reassembly methods is necessary. This paper analyzes the disk array composed of hybrid RAID and explains the layout of disk array, partition layout in hybrid RAID, and hybrid RAID configuration strategy. Furthermore, it suggests parameters that are required for RAID reassembly and then propose a hybrid RAID reassembly procedure using them. Finally, we propose a proof-of-concept tool (Hybrid RAID Reconstructor) that identifies hybrid RAID from disk array and parse RAID parameters. 相似文献

This study is the first to examine the background level of male DNA on underpants worn by females in the absence of sexual contact. Here, we examined 103 samples from the inside front of underpants from 85 female volunteers. Samples were examined for the presence of male DNA using NGM SElect and PowerPlex Y23 kits. Only five samples gave a “complete” Y-STR profile, even though 83.5% of our volunteers cohabited with a male. In all cases where a partner reference sample was available, the Y-STR profile matched the cohabiting partner. We have demonstrated that a Y-STR profile is not expected on the inside front of underpants worn by females after social contact alone. The results of this study are informative for evaluating the significance of a Y-STR profile on underpants in cases of alleged sexual assault. 相似文献

Lophophora is a member of the Cactaceae family, which contains two species: Lophophora williamsii and L. diffusa. Lophophora williamsii is an illegal plant containing mescaline, a hallucinogenic alkaloid. In this study, a novel method based on a single nucleotide polymorphism (SNP) assay was developed for identifying L. williamsii; this assay reliably detects SNPs within chloroplast DNA (rbcL, matK, and trnL-trnF IGS) and was validated for identifying Lophophora and L. williamsii simultaneously. The chloroplast DNA sequences from four L. williamsii and three L. diffusa plants were obtained and compared using DNA sequence data from approximately 300 other Cactaceae species available in GenBank. From this sequence data, a total of seven SNPs were determined to be suitable for identifying L. williamsii. A multiplex assay was constructed using the ABI PRISM® SNaPshot™ Multiplex Kit (Applied Biosystems, Forster City, CA) to analyze species-specific SNPs. Using this multiplex assay, we clearly distinguished the Lophophora among 19 species in the Cactaceae family. Additionally, L. williamsii was distinguished from L. diffusa. These results suggest that the newly developed assay may help resolve crimes related to illegal distribution and use. This multiplex assay will be useful for the genetic identification of L. williamsii and can complement conventional methods of detecting mescaline. 相似文献
