东亚-北美经济失衡与再平衡分析 总被引:1,自引:0,他引:1
本文从国别结构和产品结构分析了20世纪90年代以来东亚—北美经济失衡的变化,认为美国贸易逆差不断扩大是其对外产业转移的结果,东亚地区贸易顺差与日俱增是其承接产业转移的结果。其中,东亚内部再次产业转移导致中国顺差迅速膨胀。为了实现东亚—北美经济再平衡,美国需要采取一些措施扩大出口,控制过度的信贷消费,并对美元采取更加负责的政策;东亚地区需要努力实现由外需驱动型向内需驱动型增长方式的转变,加快产业调整与升级,并把产业链向其他地区延伸。 相似文献

This study of the impact of fair trade relies on new field data from coffee and banana co-operatives in Peru and Costa Rica, including a detailed assessment of its welfare effects by comparing FT farmers with non-FT farmers as a benchmark. Attention is focused on three major effects: (a) direct tangible impact of FT arrangements on the income, welfare, and livelihoods of rural households; (b) indirect effects of fair trade for improving credit access, capital stocks, investments, and attitudes to risk; and (c) institutional implications of fair trade for farmers' organisations and externalities for local and regional employment, bargaining, and trading conditions. Although direct effects in terms of net income remain fairly modest, important benefits are found to include capitalising farmers and strengthening their organisations. 相似文献

Preservation variance of soil DNA is neglected in the literature, and exceptional cases exaggerate amplification capabilities. This study sought to amplify a short mitochondrial fragment (212 bp) specific to Sus scrofa domesticus from the soil surrounding decomposing pig remains from an open‐air locale. Samples collected above the body at incremental distances after 145 days of initial placement yielded pig DNA. A secondary sampling was collected in 2017, approximately 768 days after burial. Inhibition tests corroborated that pig DNA was no longer present in the soil resulting in a loss of original DNA between 145 and 768 days. The results provide evidence that genetic material leaches out radially from the source and DNA fragments longer than 200 bp do not persist in soil for a relatively short timeframe in western Montana. The conclusions support the collection of soil in crime scene investigation procedures within the first few months of decomposition. 相似文献

The case of a 69‐year‐old man, equipped with an ICD and suffering from several chronic cardiac diseases, who died in a car accident, was presented. We analyzed electrogram records from the ICD explanted from the body during the autopsy, which showed that the driver had suffered from malignant ventricular arrhythmia—ventricular fibrillation (VF). A thorough analysis of the details of the accident, as well as the timing of VF and the rhythm observed after the discharge of the ICD showed that the direct cause of the accident was the episode of arrhythmia resulting in a loss of consciousness. Therefore, the presented case illustrates the usefulness of postmortem analysis of electrogram records from ICDs in the reconstruction of road traffic accidents. In such cases, if the victims are implanted with ICDs, it should be a routine procedure performed by forensic pathologists. 相似文献

This research analyses the conditions imposed on national, EU and non-EU citizens who wish to access minimum income (MI) benefits within four EU Member States, specifically within Finland, France, Ireland and Spain. The primary aim is to identify and compare the required MI access conditions. Furthermore, focus is given to the residence requisites, which are discussed in relation to relevant supranational regulations in order to detect possible multilevel implications. The paper concludes with the identification of different MI conditions, such as stricter age requisites in France and Spain. Moreover, the study of national cases allows for consideration of how the EU social protection floor works at the national level. In this regard, the restrictions that affect EU/EEA migrant jobseekers and economically inactive population groups who wish to access MI in Finland, France and Ireland show the limits of the EU minimum social assistance floor, only recognised for EU/EEA migrant workers. Finally, implications arise according to human rights instruments such as the European Social Charter, which demands that social assistance shall not be confined to nationals or to certain categories of foreigners, allowing for comparison between the different personal scopes of the equal treatment principle required by the distinct supranational levels. 相似文献

This study examines neuropsychological impairment in women who have experienced intimate partner violence using DSM 5 criteria for mild and severe cognitive impairment. A total of 108 females in Spain were included in one of three groups: psychological abuse (n = 24), physical and psychological abuse (n = 45), and no-abuse (n = 39). There were differences between the control and IPV groups in attention and executive functioning. Furthermore, approximately 25% of women experiencing IPV suffer mild neuropsychological alterations and 5% severe, mostly in memory and executive function domains. This evidence supports the growth in research that suggests psychological violence on its own to be as strongly related to poor health outcomes as physical violence in intimate partner relationships. 相似文献

Over 500 victims of the Spanish Civil War (1936–1939) were buried in the cemetery of La Carcavilla (Palencia, Spain). White material, observed in several burials, was analyzed with Raman spectroscopy and powder XRD, and confirmed to be lime. Archaeological findings at La Carcavilla's cemetery show that the application of lime was used in an organized way, mostly associated with coffinless interments of victims of Francoist repression. In burials with a lime cast, observations made it possible to draw conclusions regarding the presence of soft tissue at the moment of deposition, the sequence of events, and the presence of clothing and other evidence. This study illustrates the importance of analyzing a burial within the depositional environment and taphonomic context. 相似文献

In the last years, Science and Technology Parks (STPs) have been considered facilitators of inter-organizational relationships, as well as instruments of public policy, by creating networks and allowing access for the learning of local innovation. In this study, we propose a quantitative tool as support for measuring the efficiency of STPs through the analysis of the complex networks they form. We present a generic framework called the Inter-Relationship Science-Park Analysis (ISA) framework to study STPs at three different levels of management: (1) individual entities (research centres, universities, innovation companies, etc.); (2) STP global management; and (3) productive sector development. Moreover, we have applied the ISA framework to a real-world case study: the Walqa Science and Technology Park. Through it we have been able to know what relationships are established within this Science and Technology Park and which are the most important nodes in this network of interactions. 相似文献
