In January and March 2008, Taiwan's citizens voted primarily for domestic political reasons to oust the Democratic Progressive Party administration and promulgate the second peaceful transfer of power in Taiwan's relatively young democracy. Surveys suggest that the new administration of President Ma Ying-jeou in its first few months in office has failed to meet voter expectations. Taiwan's new international relations with the United States, Japan and China have also raised concerns both within Taiwan and overseas.
Optically stimulated luminescence (OSL) measurements are reported for single grains of quartz from deposits within Sibudu rock shelter. Such measurements enable rejection of unrepresentative grains and application of the finite mixture and central age models to obtain the most reliable age estimates. Three types of single-grain equivalent dose (De) distributions were observed: one sample represented a single dose population, three samples indicated mixing between Iron Age (IA) and Middle Stone Age (MSA) deposits, and 10 samples (in addition to the three mixed samples) showed scattered distributions. The latter type resulted from differences in the beta dose received by individual grains. For these samples, the beta doses were modelled and adjusted accordingly. Ages for the 14 samples collected from MSA deposits post-dating the Howiesons Poort (HP) resulted in three age clusters, which are stratigraphically consistent with the three informally named cultural phases at Sibudu: namely, the post-HP, late MSA and final MSA. Weighted mean ages of 58.5 ± 1.4 ka, 47.7 ± 1.4 ka and 38.6 ± 1.9 ka were calculated for these phases, respectively. The three phases were separated by two occupational hiatuses with durations of 10.8 ± 1.3 ka and 9.1 ± 3.6 ka. We hypothesise that the punctuated presence of humans at Sibudu was determined by large-scale fluctuations in climate during oxygen isotope stage (OIS) 3, which resulted in alternating wet and dry periods. Phases of occupation correspond to wet periods when fresh water was available in the Tongati River, whereas intervals of site abandonment correspond to dry periods when people were forced to migrate in search of a reliable source of fresh water. Where people migrated to, remains unresolved. 相似文献
This paper examines the wider effects of inward foreign directinvestment (FDI) to the UK on improving the practices and competitivenessof domestic industry. Surveyed domestic suppliers, competitors,and customers to foreign investors reported extensive positiveimpacts on their practices, focused particularly on reductionsin X-inefficiencies, and on their competitiveness, althoughin the case of competitors benefits had to be balanced againstadverse effects. Knowledge transfers through personal contactsand the demonstration effect, were important to the transmissionof impacts, but a number of other channels were also important,including additional supplier sales, improved customer inputs,and the competitive spur. Regional policymakers should takethese wider benefits into account in the design of policiesfor attracting and embedding foreign investment. However, whilstthere was no evidence that foreign firms in assisted regionshad fewer benefits than those in core regions, there was a lotof leakage outside of the areas attracting foreign firms, suggestingthat policies to promote spillovers should not be developedentirely in a local or regional framework. 相似文献

One purpose of the Advocacy Coalition Framework (ACF) is to explain policy change. Previous holistic reviews of the ACF by Weible, Sabatier, and McQueen (2009) and Pierce, Peterson, Jones, Garrard, and Vu (2017) of the framework have not explicitly analyzed all the concepts and their interactions in a systematic manner. To address this gap and inform scholars and practitioners about past findings, strengths, weaknesses, and opportunities for future research, this article analyzes how the ACF's theory of policy change is applied to 148 policy processes among 67 journal articles from 2007 to 2014. Similar to Weible et al. (2009), this research finds the frequent use of multiple primary pathways to policy change, infrequent use of many of the ACF's concepts, a plurality of applications in the environment and energy domain, comparison of subsystems, and a need for greater clarity and transparency among applications. Unlike Weible et al. (2009), this article explores associations between primary pathways and policy domains, the frequency of associations between primary pathways and secondary components, policy change and stasis, and identifies threats to internal validity of key ACF concepts. 相似文献
