Aid, in the form of financial aid and investment, has become increasingly prevalent in both bilateral and multilateral partnerships in the BRICS. In Africa, the Forum on China–Africa Cooperation provides the official framings for forms of development assistance to the continent, with financial forms of aid available through the New Development Bank and the China–Africa Development Bank (CADFund). This article explores how Chinese international development assistance has influenced South Africa's economic growth and development strategies and is reshaping South Africa as “gateway” to Africa and continental leader. Special economic zones (SEZs) have become a prioritised form of BRICS development collaboration particularly in terms of Chinese trade and investment expansionism into Africa through South Africa. Chinese international development assistance and foreign direct investment in South Africa in particular are very notable and have been strengthened during the Chinese official state visit prior to the Johannesburg BRICS Summit in 2018. The article critically analyses the development policy discourse on BRICS spearheading an alternative model of South–South international cooperation by examining the Coega SEZ in South Africa, hailed as the most SEZ in Africa. The article critically examines the development alternative potential of the Coega SEZ.  相似文献

Recent contributions in the domains of governance and regulation elucidate the importance of rule‐intermediation (RI), the role that organizations adopt to bridge actors with regulatory or “rulemaking” roles and those with target or “rule‐taking” roles. Intermediation not only enables the diffusion and translation of regulatory norms, but also allows for the representation of different actors in policymaking arenas. While prior studies have explored the roles that such RIs adopt to facilitate their intermediation functions, we have yet to consider how field‐level structuring processes influence (and are influenced by) the various and changing roles adopted by RI. In this study we focus on the mutually constitutive relations between field‐level change processes and the evolving roles of RIs by studying the rise of the International Council for Local Environmental Initiatives (ICLEI)/Local Governments for Sustainability, an RI serving as a bridge for sustainable urban development policies between the United Nations and local authorities. Using ICLEI as an illustrative case, we theorize four different processes of regulatory field structuration: problematization, role specialization, marketization, and orchestrated decentralization. We discuss their implications for RI roles in the field and further theorize the changing dynamics of trickle‐up intermediation processes as an RI gains power and influence.  相似文献

The residential aged care industry in Australia will expand rapidly over the next 10 years leading to substantial increases in government expenditure. Recent and future reforms are likely leading to changes in the structure of the industry with a potential impact on quality of care. The purpose of this paper is to stimulate broader public debate, based on the available evidence, about the preferred structure of this important industry. It examines the literature on the impact structure has on the quality of services and compares this with a fresh analysis of current trends. The paper argues that future policy should be evidence based and explicit about the structure of the industry that will emerge from current policy reforms.  相似文献

The usage of herbal incenses containing synthetic cannabinoids has caused an increase in medical incidents and triggered legislations to ban these products throughout the world. Law enforcement agencies are experiencing sample backlogs due to the variety of the products and the addition of new and still‐legal compounds. In our study, proton nuclear magnetic resonance (NMR) spectroscopy was employed to promptly screen the synthetic cannabinoids after their rapid, direct detection on the herbs and in the powders by direct analysis in real time mass spectrometry (DART‐MS). A simple sample preparation protocol was employed on 50 mg of herbal sample matrices for quick NMR detection. Ten synthetic cannabinoids were discovered in fifteen herbal incenses. The combined DART‐MS and NMR methods can be used to quickly screen synthetic cannabinoids in powder and herbal samples, serving as a complementary approach to conventional GC‐MS or LC‐MS methods.  相似文献

Various studies have shown that women with psychopathy tend to commit crimes that are less violent than those of psychopathic men. The present study was designed to address the influence of psychopathy on the crimes committed by female offenders. A national sample of female offenders found NGRI or of diminished responsibility and at risk for criminal recidivism (OPG patients) was compared with a sample of female offenders who were convicted and imprisoned. Results of this comparison between the two groups of female offenders indicate that psychopathy is a transversal psychopathological dimension which may or may not be associated with other mental disorders. In both samples, the most commonly reported offenses among women with high PCL‐R scores were minor offenses, not particularly violent, but they appear to be related to typical psychopathic features such as superficial charm, pathological lying, and manipulation.  相似文献

Sexual assault samples are among the most frequently analyzed in a forensic laboratory. These account for almost half of all samples processed routinely, and a large portion of these cases remain unsolved. These samples often pose problems to traditional analytic methods of identification because they consist most frequently of cell mixtures from at least two contributors: the victim (usually female) and the perpetrator (usually male). In this study, we propose the use of current preliminary testing for sperm detection in order to determine the chances of success when faced with samples which can be good candidates to undergo analysis with the laser microdissection technology. Also, we used laser microdissection technology to capture fluorescently stained cells of interest differentiated by gender. Collected materials were then used for DNA genotyping with commercially available amplification kits such as Minifiler, Identifiler Plus, NGM, and Y‐Filer. Both the methodology and the quality of the results were evaluated to assess the pros and cons of laser microdissection compared with standard methods. Overall, the combination of fluorescent staining combined with the Minifiler amplification kit provided the best results for autosomal markers, whereas the Y‐Filer kit returned the expected results regardless of the used method.  相似文献

Research Summary: The growth of prison populations over the last three decades is a great source of concern for policy makers and observers. One mechanism by which this growth occurs is via sentencing reforms that extend length of stay for certain categories of offenders. This has the effect of aging prison populations, which is problematic for many reasons. Apart from the increased financial burdens entailed in caring for older prisoners, it is also important to consider the intent of reforms in evaluating them. Of late, sentencing reform has become increasingly focused on the selective incapacitation of dangerous offenders. Policies that have the effect of aging the prison population are problematic from this perspective due to the diminishing returns realized with respect to incapacitation as offenders age. Dynamic systems simulation analysis is employed to investigate the likely consequences of recent sentencing reforms that increase length of stay for some offenders. These analyses indicate that the effects of recent reforms may not be as dramatic as some observers have predicted, but they suggest that the consideration of alternatives to incarceration for elderly offenders is warranted from the standpoint of cost considerations as well as that of selective incapacitation. Policy Implications: The results indicate that California's Three Strikes law will not accelerate the rate of growth of the elderly prison population. However, even without increasing the proportional representation of elderly prisoners, the number of elderly prisoners is expected to grow substantially over the next three decades. These prisoners will strain criminal justice system resources while presenting little public safety threat. State criminal justice policy makers and their constituents should closely examine laws that impose very long stays without discretionary release, as these statutes may contribute to the production of elderly prisoners. This problem is particularly pronounced in Three Strikes and other habitual offender laws that use retrospective methods to identify habitual offenders. Additionally, the effects of reforms lengthening stay for some offenders must be considered in light of cumulative effects of sentencing reform resulting in changes to the demographic structure of the prison population overall. Dynamic systems simulation modeling is presented as a valuable policy‐making tool, as it allows the policy analyst to examine the potential impacts of laws in the absence of data suitable for conventional statistical analyses.  相似文献

This study evaluates the assumption that deprivation among African Americans and racial inequality lead to black interracial homicide due to racial conflict and antagonism. Using refined race‐adjusted Supplemental Homicide Report data, Uniform Crime Report data and census data, we test an alternative hypothesis that draws on the macrostructural opportunity theory to assess and more accurately specify the relationship between structural characteristics and black interracial homicide. We find that first, the relationship between economic factors and black interracial homicide can be explained in large part by high rates of financially motivated crime such as robbery, and second, that economic factors are associated with financially motivated but not expressive black interracial killings. Analyses of black intraracial killings are performed for comparison purposes. Collectively, the findings suggest that conflict‐based explanations rooted in racial antagonism and frustration aggression may be premature.  相似文献

In recent years, a widespread consensus has emerged about the necessity of establishing bridges between quantitative and qualitative approaches to empirical research in political science. In this article, we discuss the use of the synthetic control method as a way to bridge the quantitative/qualitative divide in comparative politics. The synthetic control method provides a systematic way to choose comparison units in comparative case studies. This systematization opens the door to precise quantitative inference in small‐sample comparative studies, without precluding the application of qualitative approaches. Borrowing the expression from Sidney Tarrow, the synthetic control method allows researchers to put “qualitative flesh on quantitative bones.” We illustrate the main ideas behind the synthetic control method by estimating the economic impact of the 1990 German reunification on West Germany.  相似文献
