AbstractThis article provides an overview of the development of parties and party systems in the MENA region from early oligarchic pluralism to the mass single-party systems of the populist era and the limited multi-party experiments of the 1990s era of political liberalization. The survey shows how parties develop in parallel with the deepening of politicization and become nearly indispensable adjuncts in the construction of political order. The article then examines parties in the post-2010 period, with case studies of Turkey, Egypt, and Tunisia demonstrating how very different configurations of party development dramatically impact on regime trajectories, ranging from democratization to hybrid regimes. 相似文献

The leading school reform policy in the United States revolves around strong accountability of schools with consequences for performance. The federal government's involvement through the No Child Left Behind Act of 2001 reinforces the prior movement of many states toward policies based on measured student achievement. Analysis of state achievement growth as measured by the National Assessment of Educational progress shows that accountability systems introduced during the 1990s had a clear positive impact on student achievement. This single policy instrument did not, however, also lead to any narrowing in the Black‐White achievement gap (though it did narrow the Hispanic‐White achievement gap). Moreover, the Black‐White gap appears to have been adversely impacted over the decade by increasing minority concentrations in the schools. An additional issue surrounding stronger accountability has been a concern about unintended outcomes related to such things as higher exclusion rates from testing, increased dropout rates, and the like. Our analysis of special education placement rates, a frequently identified area of concern, does not show any responsiveness to the introduction of accountability systems.© 2005 by the Association for Public Policy Analysis and Management 相似文献

The objective of governments is to efficiently provide essential services and infrastructure to their jurisdictions at a competitive tax rate within the constraint of a balanced budget. In recent years, several states have found it difficult to maintain this standard. This article examines the nature of the problem in the overlapping jurisdictions of New York City and New York State. Specifically, it explains the nature of projected budget gaps that have emerged in New York, and describes how the two New Yorks' political leaders have managed their budgets in recent years. Furthermore, this article demonstrates that expenditures significantly exceed revenues, thus leading to inevitable budget gaps, and that policies designed to close the gap have harmful consequences. 相似文献

In 1973, Roe v. Wade constitutionalized a woman's right to an abortion. But, while Roe removed most legal obstacles to abortion, it did not address the limited availability of abortion services in the nation. The case examined here, Ragsdale v. Turnock, revolved around an Illinois statute that imposed far-reaching restrictions on abortion clinics, the site of most U.S. abortions since Roe. The crucial role of clinics in providing abortion services explains why the dispute represented by Ragsdale had the potential for an enormous impact on legalized abortion in the United States. Because of the number of women affected, the Ragsdale litigation could have led to the most significant judicial ruling since Roe. The suit resulted in a settlement in which plaintiffs secured the right to a legal clinic abortion during the first 18 weeks of pregnancy. Although the case was settled to the satisfaction of pro-choice advocates, a similar law today might well survive constitutional scrutiny. 相似文献

The body of a 19‐year‐old male was found apparently concealed underneath bushes with recent head and facial trauma, and multiple superficial abrasions. Subsequently, it was discovered that the decedent had been running into objects and buildings following the ingestion the evening before of what was thought to be lysergic acid diethylamide (LSD). Blood staining of a nearby wall close to where the body was lying was in keeping with the described behavior. Toxicology revealed 3,4‐methylenedioxymethamphetamine (Ecstasy), in addition to two only recently available drugs 2‐(4‐bromo‐2,5‐dimethoxyphenyl)‐N‐[(2‐methoxyphenyl)methyl]ethanamine, (25B‐NBOMe), and 1‐(3,4‐methylenedioxyphenyl)‐2‐(1‐pyrrolidinyl)‐1‐butanone, (MDPBP). At autopsy, the skull was fractured with cerebral swelling, contusions, and subarachnoid hemorrhage. Death was due to blunt cranial trauma against a background of mixed drug toxicity. The case demonstrates a rare cause of death in a drug‐induced acute delirium, as well as highlighting two new designer street drugs that may result in significant aberrant behavior. 相似文献

The ACHIEVEability model of affordable housing aims to promote self-sufficiency by requiring enrollment in postsecondary education in exchange for subsidized housing. In this study, we exploit the quasi random assignment of ACHIEVEability participants (N = 84) to subsidized housing units to evaluate whether microneighborhood environments moderated participants’ progress in postsecondary education. Participants progressed in their educational pursuits in line with program requirements, earning about 12 college credits per year. Neighborhood block group characteristics moderated this progress. Participants who were assigned to housing located in poorer, more violent, and less educated block groups earned credits at a significantly slower rate than participants assigned housing in more advantaged block groups. Our results suggest that the micro environments immediately surrounding residents of subsidized housing matter, even if they are situated within broader contexts of spatial and personal disadvantage. 相似文献

Drawing forensic conclusions from an image or a video is known as “photographic content analysis.” It involves the analysis of an image, as well as objects, actions, and events depicted in images or video. In recent years, photographic depictions of objects suspected as illegal firearms have substantially increased, appearing on CCTV surveillance footage, captured by mobile phones and shared on social media. However, the law in Israel states that a person can be charged with illegally possessing a firearm only if it can be proven that the object is capable of shooting with lethal bullet energy. This becomes more challenging in cases where the firearm was not physically seized, and the evidence exclusively consists of images and video. In this study, photographic content analysis was applied to images and video where objects suspected as commercial or improvised firearms had been depicted. An image and event sequence reconstruction video databases of both firearms and replicas were created in order to better define firearm-specific functional morphological features. We demonstrate that it is possible to classify an object as a firearm by analyzing the functional, and not only the esthetic, morphology in images and video. It is also shown that event sequence reconstruction in video may be used to infer that an object suspected as a firearm has the capacity to shoot by confirming the occurrence of a shooting act or shooting process. Thus, photographic content analysis may be used to forensically establish that an object depicted in an image or a video is a firearm by ruling out other known scenarios, and without physically seizing it. 相似文献

TASER® weapons are conducted energy weapons (CEWs) that are frequently used by police departments around the world. CEWs can be deployed in two methods: drive stun application and probe deployment. This study aims to examine damages caused by TASER devices on fabrics and whether types of fabric material and TASER models could contribute to different damage features. Three types of white fabric were used, including 100% cotton, 100% polyester, and 65:35 polyester-cotton blend. Three models: TASER X26P, TASER X2, and TASER 7 were shot onto each type of fabric, with five repetitions each. Each damaged area on the fabric caused by a probe is a sample (n = 90) and was examined with a Keyence digital microscope. Images were captured by the Keyence microscope and measurements were recorded, including damage dimensions, fabric condition, evidence of burning, and extra findings. The presence of fused yarn ends was found to be statistically significant across the fabric types, and no damage features were found that may assist in the identification of TASER models. Other damage features including damage dimensions, discoloration, and fiber deformation were not found to be showing apparent differences according to statistical analysis. The conclusions made by this research should be used with caution due to the small sample size. 相似文献

The benzylation of three low molecular weight N,N-disubstituted ethanolamines related to chemical warfare agents (CWAs) to furnish derivatives with improved gas chromatography-mass spectrometry (GC-MS) profiles is described. Due to their low molecular weight and polar nature, N,N-disubstituted ethanolamines are notoriously difficult to detect by routine GC-MS analyses during Organisation for the Prohibition of Chemical Weapons (OPCW) proficiency tests (PTs), particularly in scenarios when they are present at low levels (~1–10 ppm) amidst more abundant interferences. Our studies revealed that the optimal derivatization conditions involved the treatment of the ethanolamine with benzyl bromide in the presence of an inorganic base (e.g., Na2CO3) in dichloromethane at 55°C for 2 h. This optimized set of conditions was then successfully applied to the derivatization of N,N-dimethylethanolamine, N,N-diethylethanolamine and N,N-diisopropylethanolamine present separately at 1 and 10 μg/mL concentrations in a glycerol-rich matrix sample featured in the 48th OPCW PT. The benzylated derivatives of the three ethanolamines possessed retention times long enough to clear the massive glycerol-containing matrix interferences. The protocol herein is introduced as an alternative method for derivatization of these CWA and pharmaceutically important species and should find broad applicability in laboratories where routine forensic analysis is carried out. 相似文献
