Facing new agenda economic development issues, China like other developing states is forced to coordinate policies regionally. As need for decentralization “downward” stretches to include delegation “outward,” Beijing must find its best response to the new trend. Four tests reveal no reason for China to stay aloof from simple Membership in Pacific-Asian regional organizations. Three tests reveal no problem with China taking an Activist role in such regional organizations. Three final tests reveal potential costs China would pay for seeking a regional Leadership role, especially before Beijing's post-succession direction is determined.  相似文献

This study estimates for 1989 the cost in Canada of the products and services consumed by a representative urban Chinese family in the second highest income quintile. The ratio of this figure, called the purchasing power parity cost, to the figure obtained by converting the yuan cost of the consumption to dollars at the exchange rate was 10.5. This ratio is very much higher than the ratio for other underdeveloped countries, and reasons for the difference are examined.  相似文献

The article evaluates the body of literature on Leonardo da Vinci using for the first time bibliometric and altmetric methods for data processing. The question of whether the literature on Leonardo da Vinci reflects his interdisciplinarity as scientist and artist is addressed. We argue that the medical and material sciences show a high number of citations to the respective publications, and much higher number of citations to publications ratio than the humanities and social sciences fields. We also found that there is no relationship between the number of publications for each research area and the citations (between productivity and quality). The largest category of papers, in terms of citations and in terms of the number of subfields, discussing da Vinci’s contribution to the various sciences, belongs to exact sciences. This finding is surprising as Leonardo da Vinci has become a synonym for the mysterious artist whose paintings consist of many messages that are difficult to explain. Therefore it seems natural that Leonardo the artist would get a lot of research attention. Nevertheless, the bibliometric findings show that the academic community has interest in his contributions to science, no less than in his work of art.  相似文献

This paper compares over a 12‐year period (1) patterns of contracting between a state transportation agency and its prime contractors providing engineering design services with (2) patterns between these prime contractors and their subcontractors. We find evidence of different contracting patterns at each level that emerge over time and coexist in the same contracting context. While patterns at the agency–prime level are characterized by repeated contracts, patterns at the prime–sub level indicate fewer repeats and more contractor turnover. Implications for outsourcing practice and theory are discussed. © 2011 by the Association for Public Policy Analysis and Management.  相似文献

One of the aims of forensic science is to determine the identities of victims of crime. In some cases the investigators may have ideas as to the identities of the victims and in these situations, ante mortem photographs of the victims could be used in order to try and establish identity through skull-photo superimposition. The aim of this study was to evaluate the accuracy of a newly developed digital photographic superimposition technique on a South African sample of cadaver photographs and skulls. Forty facial photographs were selected and for each photo, 10 skulls (including the skull corresponding to the photo) were used for superimposition. The investigator did not know which of the 10 skulls corresponded to the photograph in question. The skulls were scanned 3-dimensionally, using a Cyberware? Model 3030 Colour-3D Scanhead scanner. The photos were also scanned. Superimposition was done in 3D Studio Max and involved a morphological superimposition, whereby a skull is superimposed over the photo and assessed for a morphological match. Superimposition using selected anatomical landmarks was also performed to assess the match. A total of 400 skull-photo superimpositions were carried out using the morphological assessment and another 400 using the anatomical landmarks. In 85% of cases the correct skull was included in the possible matches for a particular photo using morphological assessment. However, in all of these cases, between zero and three other skulls out of 10 possibilities could also match a specific photo. In the landmark based assessment, the correct skull was included in 80% of cases. Once again, however, between one and seven other skulls out of 10 possibilities also matched the photo. This indicates that skull-photo superimposition has limited use in the identification of human skeletal remains, but may be useful as an initial screening tool. Corroborative techniques should also be used in the identification process.  相似文献

Background: Parents with intellectual disability and Aboriginal and Torres Strait Islander parents are overrepresented in child removal but research has not explored the intersection of Aboriginality and intellectual disability in child protection.

Methods: A case file review of 45 parents with intellectual disability (n = 14 Aboriginal and n = 31 non-Aboriginal) engaged in care proceedings in New South Wales was undertaken. Parent and child demographics and investigation triggers and outcomes were compared.

Results: Aboriginal parents were significantly younger than non-Aboriginal parents at initiation of an investigation, twice as likely to be investigated due to concerns about parenting capacity, and more likely to have children removed than non-Aboriginal parents.

Conclusion: The intersection of Aboriginality and intellectual disability appears to increase the risk of negative encounters with child protection systems. Targeted support for young Aboriginal parents and greater disability awareness and cultural sensitivity by child welfare workers are needed.  相似文献
