Introduction     
The idea of the Third World, which is usually traced to the late 1940s or early 1950s, was increasingly used to try and generate unity and support among an emergent group of nation-states whose governments were reluctant to take sides in the Cold War. These leaders and governments sought to displace the ‘East–West’ conflict with the ‘North–South’ conflict. The rise of Third Worldism in the 1950s and 1960s was closely connected to a range of national liberation projects and specific forms of regionalism in the erstwhile colonies of Asia and Africa, as well as the former mandates and new nation-states of the Middle East, and the ‘older’ nation-states of Latin America. Exponents of Third Worldism in this period linked it to national liberation and various forms of Pan-Asianism, Pan-Arabism, Pan-Africanism and Pan-Americanism. The weakening or demise of the first generation of Third Worldist regimes in the 1960s and 1970s coincided with or was followed by the emergence of a second generation of Third Worldist regimes that articulated a more radical, explicitly socialist, vision. A moderate form of Third Worldism also became significant at the United Nations in the 1970s: it was centred on the call for a New International Economic Order (nieo). By the 1980s, however, Third Worldism had entered into a period of dramatic decline. With the end of the Cold War, some movements, governments and commentators have sought to reorient and revitalise the idea of a Third World, while others have argued that it has lost its relevance. This introductory article provides a critical overview of the history of Third Worldism, while clarifying both its constraints and its appeal. As a world-historical movement, Third Worldism (in both its first and second generation modalities) emerged out of the activities and ideas of anti-colonial nationalists and their efforts to mesh highly romanticised interpretations of pre-colonial traditions and cultures with the utopianism embodied by Marxism and socialism specifically, and ‘Western’ visions of modernisation and development more generally. Apart from the problems associated with combining these different strands, Third Worldism also went into decline because of the contradictions inherent in the process of decolonisation and in the new international politico-economic order, in the context of the changing character, and eventual end, of the global political economy of the Cold War.  相似文献

The impact of rising powers generally and the BRICS - Brazil, Russia, India, China and South Africa - in particular on the existing global order has become controversial and contested. Donald Trump’s nationalist foreign policy agenda has raised questions about the BRICS willingness and capacity to provide leadership in place on an American administration that is increasingly inward looking. As a result, the rise of BRICS poses potential normative and structural challenges to the existing liberal international order. Given its geoeconomic significance, China also poses a potential problem for the other BRICS, as well as the governance of the existing order more generally. Consequently, we argue that it will be difficult for the BRICS to maintain a unified position amongst themselves, let alone play a constructive role in preserving the foundations of ‘global governance’.  相似文献

In his 1997 analysis of the history of Tibetan and Chinese relations (The Snow Lion and the Dragon), Melvyn Goldstein advised in his concluding chapter that Tibetans were unlikely to indefinitely put up with the Chinese occupation of Tibet without resorting to violence. However, despite continuing speculation, more widespread or sustained campaigns of violence have largely failed to materialize. The principle objectives of this study are to establish why the scale of violence that Goldstein warned about has so far failed to emerge; and to assess whether existing evidence supports or undermines claims that violence may in the future emanate from Tibetan exile communities in India. It will be argued that previous analyses have been premised on a relatively narrow assessment of the situation and context, and that a more informed and nuanced evaluation of the potential for future violence requires comprehensive analysis of a much wider range of factors.  相似文献

Two deaths involving 3, 4‐methylenedioxypyrovalerone (MDPV) are reported. MDPV is a synthetic cathinone stimulant found in “bath salts” with neurological and cardiovascular toxicity. Biological specimens were analyzed for MDPV by GC/MS and LC/MS. A White man was found dead with signs of nausea and vomiting after repeatedly abusing bath salts during a weekend binge. Femoral venous blood and urine had MDPV concentrations of 39 ng/mL and 760 ng/mL. The second fatality was a White man with a history of drug and bath salt abuse found dead at a scene in total disarray after exhibiting fits of anger and psychotic behavior. Femoral venous blood and urine had MDPV concentrations of 130 ng/mL and 3800 ng/mL. The blood and urine MDPV concentrations are within the reported recreational concentration ranges (blood 24–241 ng/mL and urine 34–3900 ng/mL). Both decedents’ deaths were attributed to relevant natural causes in a setting of MDPV abuse.  相似文献

Though the co-occurrence rate of intimate partner violence (IPV) and problems with alcohol and other drugs (AOD) is 50 % or higher among men in clinical samples, little attention has been given to examining the characteristics of batterers with AOD problems (AOD batterers). We compared 274 AOD batterers and 524 non-AOD Batterers (batterers who do not have AOD problems). Results indicated AOD batterers were more violent, and were more likely to perpetrate violence that is severe in nature. They also reported higher levels of anger and trauma, had a greater proclivity toward a borderline personality orientation, and were much more likely to use AOD during an incident of violence at least half of the time (41 % versus 9 %). Results underscore the need for screening of batterers for AOD problems and substance abusers for IPV, and suggest that AOD problems might serve as an important indicator to help identify particularly complex cases.  相似文献

A writer's biometric identity can be characterized through the distribution of physical feature measurements (“writer's profile”); a graph‐based system that facilitates the quantification of these features is described. To accomplish this quantification, handwriting is segmented into basic graphical forms (“graphemes”), which are “skeletonized” to yield the graphical topology of the handwritten segment. The graph‐based matching algorithm compares the graphemes first by their graphical topology and then by their geometric features. Graphs derived from known writers can be compared against graphs extracted from unknown writings. The process is computationally intensive and relies heavily upon statistical pattern recognition algorithms. This article focuses on the quantification of these physical features and the construction of the associated pattern recognition methods for using the features to discriminate among writers. The graph‐based system described in this article has been implemented in a highly accurate and approximately language‐independent biometric recognition system of writers of cursive documents.  相似文献

The premise of this study was to take a valid population sampling of handwriting and handprinting and assess how many times each of the predetermined characteristic is found in the samples. Approximately 1500 handwriting specimens were collected from across the United States and pared to obtain a representative sample of the U.S. adult population according to selected demographics based on age, sex, ethnicity, handedness, education level, and location of lower‐grade school education. This study has been able to support a quantitative assessment of extrinsic and intrinsic effects in handwriting and handprinting for the six subgroups. Additional results include analyses of the interdependence of characteristics. This study found that 98.55% of handprinted characteristics and 97.39% of cursive characteristics had an independence correlation of under 0.2. The conclusions support use of the product rule in general, but with noted caveats. Finally, this study provides frequency occurrence proportions for 776 handwriting and handprinting characteristics.  相似文献

A four‐year‐old previously well boy collapsed unexpectedly and was taken immediately to hospital, where he developed seizures and cardiogenic shock with lethal, rapidly progressing multi‐organ failure. At autopsy, the height was >90th percentile and there were indications of early virilization. Internally, a friable tumor of the left adrenal gland was identified that had invaded the left renal vein and inferior vena cava. Histology revealed typical features of an adrenocortical carcinoma with aggregated trabeculae of cells containing abundant eosinophilic cytoplasm and large pleomorphic nuclei. There was strong positive cytoplasmic staining for inhibin; mitochondria were shown on electron microscopy to contain prominent electron‐dense granules. Death was due to massive pulmonary tumor embolism. Although adrenocortical carcinomas are very rare and are more commonly found in adults, the current case demonstrates that they may also occur in childhood and be responsible for unexpected death by the very unusual mechanism of tumor embolism.  相似文献

Recent research has expanded our understanding of sexual homicide offenders (SHOs). However, little exists beyond case reports for older SHOs. We characterized male SHOs ≥ 55 years, comparing them to typical adult male SHOs who are in their 20s. Analysis of 37 years (1976–2012) of US Supplementary Homicide Reports data provided a large SHO sample (N = 3453). Three case reports provide clinical context for the diverse nature and patterns of older SHOs. Only 32 older male SHOs and no older female SHOs were identified. Murders by older SHOs accounted for only 0.5% of US sexual homicides. Unlike typical SHOs that generally target young adult females, over two‐thirds of older SHO victims were ≥40 years, and one‐third were ≥55 years. Sexual homicides by older SHOs, like sexual homicide in general, decreased over the study period. These crimes, while exceedingly rare, do occur, warranting special consideration.  相似文献

Introduction: Liaison and Diversion (L&D) currently serves 50% of the population of England. L&D relies on modified working practices with key delivery partners, especially the police. Service evaluation data is thus presented from both police and health services. Method: A before and after intervention review of 3 months of operational data of L&D in Cornwall focusing on health, criminal and economic outcomes. Results: After L&D intervention individuals’ contact with the police as either victim or perpetrator reduced significantly. Implications: Preliminary findings suggest that L&D enabled reduced use of police and criminal justice resources. National reporting procedures may be unable to demonstrate the multi-agency impact if criminal justice data are not considered within the outcome data-set. Recommendations echo international observations that specifying outcome measures and the consistent definition of L&D services would enable generalisation of findings.  相似文献
