Underneath impressive growth levels, the Chilean economy displays signs of being caught in a middle‐income trap. It has been unable to improve its productivity, increase the added value of its exports or upgrade its value chain. Its economy cannot compete either with low‐wage countries or highly productive, innovative countries. Its export strategy based on export promotion seems to have outlived its usefulness. It achieved remarkable quantitative success, but must now attend qualitative attributes. Instead of regarding market‐driven export promotion and state‐led export development as substitutes, this article proposes to view them as alternatives in different stages of development. To choose the appropriate time, more attention should be given to non‐traditional, structural indicators, like export sophistication and political‐institutional capabilities. 相似文献

Several colorectal cancer (CRC) screening models have been developed describing the progression of adenomas to CRC. Currently, there is increasing evidence that serrated lesions can also develop into CRC. It is not clear whether screening tests have the same test characteristics for serrated lesions as for adenomas, but lower sensitivities have been suggested. Models that ignore this type of colorectal lesions may provide overly optimistic predictions of the screen‐induced reduction in CRC incidence. To address this issue, we have developed the Adenoma and Serrated pathway to Colorectal CAncer (ASCCA) model that includes the adenoma‐carcinoma pathway and the serrated pathway to CRC as well as characteristics of colorectal lesions. The model structure and the calibration procedure are described in detail. Calibration resulted in 19 parameter sets for the adenoma‐carcinoma pathway and 13 for the serrated pathway that match the age‐ and sex‐specific adenoma and serrated lesion prevalence in the COlonoscopy versus COlonography Screening (COCOS) trial, Dutch CRC incidence and mortality rates, and a number of other intermediate outcomes concerning characteristics of colorectal lesions. As an example, we simulated outcomes for a biennial fecal immunochemical test screening program and a hypothetical one‐time colonoscopy screening program. Inclusion of the serrated pathway influenced the predicted effectiveness of screening when serrated lesions are associated with lower screening test sensitivity or when they are not removed. To our knowledge, this is the first model that explicitly includes the serrated pathway and characteristics of colorectal lesions. It is suitable for the evaluation of the (cost)effectiveness of potential screening strategies for CRC. 相似文献

旅游交通是旅游经济发展中重要的内容之一,通过对中国十大城市群城市旅游交通可达性、铁路交通流分布情况与旅游经济联系、总量和隶属度进行计算,借助Arcgis10.2对中国十大城市群交通空间流分布情况和旅游经济联系进行空间可视化处理,并对计算结果进行综合比较分析。研究发现:高铁使得中国十大城市群城市旅游交通可达性水平得到大幅提升,且交通流分布均衡。中国十大城市群城市可达性的提升给城市旅游经济带来了一定的积极影响。高铁网络下中国十大城市群旅游经济联系分布不均衡。 相似文献

This paper evaluates economic impacts arising from the introduction of high-speed rail (HSR) between Madrid and Barcelona. Using difference-in-differences estimation we estimate an average treatment effect for provinces with stops on the HSR line of 2.4% for economic output, 3.3% for numbers of firms, and 1.1% for labour productivity. We complement our DID results with a synthetic control analysis for Lleida and Tarragona, two provinces that we argue were assigned HSR stations largely due to their incidental location. We find that both the number of firms and labour productivity are substantially higher in these provinces than in their synthetic counterparts. 相似文献

The opportunity to live authentically is critical for the well-being of transgender individuals. For many this requires accessing transition-related services. Current knowledge of transition-related care is limited. This study aims to elucidate experiences and needs of transgender individuals (N = 65) related to (a) therapeutic support, (b) medical care, and (c) aspects of living authentically in order to inform the development and delivery of trans-affirmative services. Findings reveal challenges accessing health care providers with trans-specific competency; gaps between critical aspects of transition-related care and receipt of services; and heterogeneity of experiences and needs. Recommendations for improving transgender-affirmative services are provided. 相似文献

工业化、城市化形塑了人口流动的方向,这使得我国东部乡村与中西部乡村的社会性质产生了巨大分化。在工业化与人口大量流入的背景下,东部地区村庄逐步成为土客杂居的工业型村庄,“类熟人社会”成为工业型村庄社会结构的新形态。学界既有概念“无主体熟人社会”揭示了作为人口流出地的中西部农业型村庄社会结构的新形态,而“类熟人社会”与其相对应,形成对转型期中国乡村社会性质的互补性解释。在东部地区工业型村庄中,通过原生型社会关系与建构型社会关系,人们的“熟悉”感开始建立,但最终却形成了“熟而不亲”的类团体格局。类熟人社会的形成,有赖于人们在流动社会里,通过“区隔化”和“聚类化”的策略,在保障生存安全的前提下,实现生计的维持。过日子的区域差异,也使得各群体之间很难在短时间内实现融合。 相似文献

Midlife transition is an inevitable process that every adult faces during his or her life. As Generation Xers move into middle age, the field of human resource development (HRD) should keep pace with the impact of this midlife transition on this cohort’s psychological and physical welfare and continuous development. An effective way to cope with midlife transition is to face it as an opportunity for change and self-actualization. Gender as well as physical and psychological changes are important factors in midlife transition. Organizations should understand the challenges of midlife transition and create a supportive environment for Generation Xers to cope with the changes. Specific suggestions for middle-aged Generation Xers and HRD professionals are provided in this article, as well as implications and recommendations. 相似文献

This article examines how young Filipino men looking to work in international seafaring deploy servitude as a means of attaining education-to-work transition. It focuses on those applying to work for free as ‘utility men’ (gofer or flunkey) in Manila’s manning and crewing agencies that supply seafarers to ship operators around the world in exchange for the promise of boarding a ship. Based on participant observation and life history interviews, the article accounts for how they transform their servitude into diskarte – strategy by which they navigate the limited employment opportunities in the Philippines – by constructing their ‘utility manning’ as an informal and negotiated pathway to employment. The young Filipino men’s seeking and enduring servitude, geared towards gleaning better social possibilities, becomes a profoundly rational act of investing in and securing their future. 相似文献

In recent decades, accelerating processes of globalization and an increase in economic inequality in most of the world's countries have raised the question of the emergence of a new bourgeoisie integrated at the global level, sometimes described as a global super-bourgeoisie. This group would be distinguished by its unequaled level of wealth and global interconnectedness, its transnational ubiquity and concentration in the planet's major global cities, its specific culture, consumption habits, sites of sociability and shared references, and even by class consciousness and capacity to act collectively. This article successively discusses how the social sciences have examined these various dimensions of the question and begun to provide systematic empirical answers. 相似文献
