The Diffusion of Human Trafficking Policies in the Post-Soviet Region: A Comparative Analysis of Policy Adoption in Ukraine,Latvia, and Russia

This paper analyzes how human trafficking policies diffused in the post-Soviet region. By adapting the diffusion of innovation framework to fit the international context, I examine whether human trafficking adoptions in the post-Soviet region were due to internal determinants and/or diffusion effects. A comparison of Russia, Latvia, and Ukraine found that internal determinants such as state commitment to human trafficking policy and interest group strength were more important to policy adoption than external pressures from the international community while state capacity and bureaucratic restructuring impeded policy adoption. I argue that policymaking, even in authoritarian regimes, is more nuanced than blind compliance with international treaties and shows that interest groups and policy entrepreneurs work within the constraints of national policymaking to adopt human trafficking policies.     

State Transitions from Rigidity to Fragility and Failure: The Case of Middle East and North Africa

ABSTRACT

The taxonomy of the state’s effective governance capacity present in the literature is evolving around state fragility. However, this article argues that a state moves along the state transition curve, resulting in governance capacity variations over time. It begins as a fragile state, consolidating to becoming a vibrant state, only to embark, eventually, on a downward trajectory through phases of rigidity, decaying, and fragility, before becoming a failed state. About one-third of MENA (Middle East and North Africa) countries are either fragile or failed states. Only technological change and knowledge accumulation and diffusion can shift this curve upward, thereby increasing a state’s effective governance capacity.     

Spatial Distributions of Oxygen Stable Isotope Ratios in Tap Water From Mexico for Region of Origin Predictions of Unidentified Border Crossers

One of the many difficulties associated with identifying undocumented border crossers stems from an inability to narrow down the search area for the region of origin and family members to obtain family reference samples for DNA comparison. While the geography of regions of origins is wide, the biological profiles of the undocumented border crossers often show strong similarities, young and male. The isotopic composition of human bones, teeth, and hair has been demonstrated to be useful biomarkers for tracing locations and movements of individuals and for aiding in the identification of human remains. Data obtained from human remains can be compared to and aligned with various reference sources, such as soils and bedrock, archaeological remains, or cultural data. Here, the spatial deficiency in isotopic reference data for Mexico, specifically for oxygen (δ¹⁸O) isotopes in tap water, is being addressed through the collection and analysis of over 150 water samples and explored with tooth enamel isotopic values from recently identified Mexican nationals. The isoscape was developed using a Spine with Barriers interpolation method and shows sufficient detail to narrow down the regions where specific isotopic values are represented. The individuals were plotted on the developed isoscape using conditional correlations. The methodology was successful in assigning the correct regions of origin for the two individuals, which shows the tremendous potential of the developed isoscape. Nonetheless, there is more research needed to further improve upon this geolocation method, including analysis of multiple isotopes in different tissues, and the development of new isotopic methods.     

海峡经济区竞争性区域体系构建研究

竞争性区域是拥有独特“地方品质”的区域,以创新和知识作为其发展的催化剂,成为国家乃至全球最具发展活力的区域。竞争性区域的构建过程集中体现为提升区域竞争力的战略政策要点和与此相配套实施的多级治理措施的高效统一。从竞争性区域构建理论视角考察,海峡经济区作为两岸经济整合的独特区域,其基础设施网络连接性、产学研互动合作、产业集群培育、城市经济协同发展方面亟待推进,竞争性区域特质尚不发育。今后应从基础设施的协调与衔接、区域产业分工协作体系建立、厦金特区和福马特区创建、经济运行机制衔接、台湾海峡城市联盟缔结、开展以政府政策协调为中介的公私合营等方面着力推进,以构建海峡经济区竞争性区域配套体系,推动海峡经济区迅速崛起成为中国乃至世界新兴的竞争性区域。

先秦巴蜀地区百濮和氐羌的来源

先秦巴蜀地区各族,除巴、蜀两族外,主要为百濮和氐羌两大民族系统。巴蜀地区的百濮,多为商周时代即已在当地定居的族群,也有春秋时代从江汉地区迁徙而来的濮人支系,主要分布在四川盆地、四川西南和四川东部。巴蜀地区的氐羌民族系统至少在夏商时代就已出现,主要分布在川西高原。     

西部民族地区城镇化建设中税收优惠的法律经济学研究

本文在分析现阶段西部民族地区的税收优惠政策及其局限性的基础上,从法律经济学效益最大化的思想出发,指出在西部民族地区城镇化建设的税收优惠中必须依法治税,应当赋予部分西部民族地区政府地方税收立法权,还要落实西部民族地区自治机关的税收管理自治权。
