This article analyses the pattern of technology imports and its influences on China's indigenous technology. Indigenous technology consists of two dimensions: technology generation measured by R&;D and spending on technical upgrading; and application measured by output value of heavy industry and its export value respectively. The analysis reveals increased reliance on foreign loans to finance technology imports, diversified sources of supply, and strong emphasis on the purchase of disembodied technology after the late 1970s. Based on time series data from 1960 to 1991, statistical evidence indicates that imported technology has significantly enhanced China's technological build‐up. Imported technology is positively correlated with both dimensions.  相似文献

In the United States at this time, no uniform federal law exists regarding commercial surrogacy, and state statutory schemes vary vastly, ranging from criminalization to legal recognition with contract enforcement. The authors examine how commercial surrogacy agencies utilize the Internet as a means for attracting parents and surrogates by employing emotional cultural rhetoric. By inducing both parents and surrogates to their jurisdiction, agencies circumvent vast discrepancies in state statutory regulative schemes and create a distinct interstate business, absent an efficient regulatory framework or legal recourse in some circumstances. The authors propose a uniform federal regulatory scheme premised upon regulating interstate business transactions to create accountability and legal remedies for both the parents and the surrogate.  相似文献

This paper examines autopoietic theory with reference to functionally differentiated social sub-systems, particularly law, science, and politics. It sets out to 'test' the practical relevance of autopoietic theory in relation to ongoing debates about post-adoption contact and personal identity issues. Law has resisted social scientific pressure to regulate post-adoption contact in the context of a social policy approach, which emphasizes the relationship between identity development and genealogical continuity. I argue that law's response to this pressure relates to the particular nature of adoption as this is expressed through legislation and case law. Law's refusal to intervene in post-adoption contact reflects its self-referential operations and its attempts to avoid epistemic entrapment by a social scientific discourse. Applying autopoietic theory to law's practical operations in adoption clarifies its explanatory value, provides a conceptual framework for understanding the relationship between law, politics, and social science and indicates areas that require theoretical refinement.  相似文献

In a case of a driving ability assessment, hair analysis for ethyl glucuronide (EtG) was requested by the authorities. The person concerned denied alcohol consumption and did not present any clinical sign of alcoholism. However, EtG was found in concentrations of up to 910pg/mg in hair from different sampling dates suggesting an excessive drinking behavior. The person declared to use a hair lotion on a regularly base. To evaluate a possible effect of the hair lotion, prospective blood and urine controls as well as hair sampling of scalp and pubic hair were performed. The traditional clinical biomarkers of ethanol consumption, CDT and GGT, were inconspicuous in three blood samples taken. EtG was not detected in all collected urine samples. The hair lotion was transmitted to our laboratory. The ethanol concentration in this lotion was determined with 35g/L. The EtG immunoassay gave a positive result indicating EtG, which could be confirmed by GC-MS/MS-NCI. In a follow-up experiment the lotion was applied to the hair of a volunteer over a period of six weeks. After this treatment, EtG could be measured in the hair at a concentration of 72pg/mg suggesting chronic and excessive alcohol consumption. Overnight incubation of EtG free hair in the lotion yielded an EtG concentration of 140pg/mg. In the present case, the positive EtG hair findings could be interpreted as the result of an EtG containing hair care product. To our knowledge, the existence of such a product has not yet been reported, and it is exceptionally unusual to find EtG in cosmetics. Therefore, external sources for hair contamination should always be taken into account when unusual cosmetic treatment is mentioned. In those cases, it is recommended to analyze the hair product for a possible contamination with EtG. The analysis of body hair can help to reveal problems occurring from cosmetic treatment of head hair. As a consequence, the assessment of drinking behavior should be based on more than one diagnostic parameter.  相似文献
