Abstract

Numerous studies have shown that there is a structural gap between restrictive migration policies and expansive inflows in democratic countries; yet scholars have not sufficiently reflected on how this gap is shaped in times of crisis. Focusing on the case of Italy in the decade between 2007 and 2017, this article assesses the extent to which the different challenges triggered by the economic and humanitarian crises have affected the structural gap, and which actors have mostly contributed to shape it. Our analysis of the Italian case shows how in the decade of the economic crisis the migration policy gap has not been the result of pressure by actors in the economic and liberal norm spheres, but rather reflects conflictual relationships within the political-institutional sphere between Italian governments and EU institutions.  相似文献

This article presents the case against immigration controls. Nation states, which are giving up controls on the movement of goods and capital, nevertheless still try to control the movement of people. Like controls under apartheid, immigration controls will eventually become untenable. They are also a relatively recent phenomenon. The actions of the governments of the rich countries, their international agencies and corporations increase both the opportunities and the need for migration. Together with arms sales and support for right-wing repressive regimes, they bear much responsibility for the wars and persecution from which people are forced to flee. The strongest reason for abolishing immigration controls is the increasingly harsh suffering they impose on refugees and migrants, largely to deter others. In the process, they undermine many human rights, including potentially those of existing residents.  相似文献

The rule of law and security sector reform have become central to peacebuilding initiatives in the past decade and a half, accompanying a surge in international interventions in the periphery. Considered of critical importance to the re-establishment of order and the promotion of peace and development, these two areas of reform have gained importance and, today, feature as priorities in the European Union’s external action beyond its immediate neighbourhood. Such policies, however, have often failed to achieve their stated goals. After reviewing the theoretical relationship between peacebuilding, rule of law reform and security sector reform, this article draws on the Union’s practice to argue that a narrow, formalistic approach to rule of law and security sector reform, one that prioritises the transplantation of a western liberal legal framework, has undermined the aims of curbing instability and fostering development.  相似文献

Acetone presence in human biological specimens can result from exogenous administration or endogenous production, resulting from diabetes, dietary composition, alcoholism, and stress response. Victims of drug-facilitated sexual assaults (DFSA) are understood to experience enhanced stress. At the Harris County Institute of Forensic Sciences (HCIFS), DFSA drug testing includes analysis of volatile compounds, ethanol, methanol, isopropanol, and acetone, by headspace gas chromatography/flame ionization detection. The prevalence of acetone-positive specimens in DFSA casework has been observed to exceed that of other human performance case types. In this report, DFSA cases received between 2019 and 2021 (n = 393) were reviewed and 41 acetone-positive cases were detailed. Overall, nearly 11% of the DFSA cases had acetone-positive blood or urine specimens, where 3% identified acetone only, 6% identified acetone and other drug(s), and 2% identified acetone, ethanol, and other drug(s). Acetone concentrations ranged from 0.010 to 0.147 g/100 mL in urine. Other drugs such as nor-carboxy-Δ9-tetrahydrocannabinol, amphetamine, methamphetamine, ethanol, and benzoylecgonine were commonly detected. Elevated stress response encountered during DFSAs may facilitate the mechanism behind enhanced acetone production leading to increased identification. Limited availability of victim medical history precludes understanding the contribution of other disease states or physiological conditions. Nonetheless, the identification of acetone in DFSA specimens supports its potential as a biomarker of trauma in forensic toxicology casework and warrants future research within the community.  相似文献

This investigation intends to study materials and techniques used for biological evidence collection in sexual assault cases and is divided into two stages: in stage one, methods for biological evidence collection (the single swab (including three variants) and the “double swab technique”) were compared; in stage two, swabs’ component material was compared. The sampling was composed of 42 heterosexual couples who provided mock samples. The collection methods in which the whole swab is covered by evidence presented significantly better outcomes (< 0.001), such as the “double swab technique.” Additionally, nylon swabs proved to present significantly better features regarding the capacity of sample elution, providing significantly higher amounts of DNA ( 0.034). This study provides guidelines for better collection of biological evidence regarding the collection method using a swab and the proper swab material to utilize.  相似文献

A Midwestern state’s child welfare agency contracted with a university to evaluate a 5-year Title IV-E Waiver Demonstration Project. As part of the process study, evaluators employed case study analysis to investigate Waiver knowledge and effects as reported by Regional and Executive Managers across 4 years of the demonstration period. Data from 78 interviews reveal enhanced levels of manager–evaluator rapport and integrated Waiver knowledge across years of data collection. This study highlights the value of middle managers as rich data sources, studying process through qualitative methods in child welfare evaluation, and how consistent relationships can support partnerships over time.  相似文献
