Economic growth and environmental "friendliness" are the dual missions of China's grand western development. In the past eight years,China has seen the gap between eastern and western regions still widening while also taking on the arduous task of protecting nature,ecology and environment in the western region. How has western development fared in the past eight years? What difficulties and challenges are being encountered? The development of the western region poses the single greatest difficulty facing China's regional economic development,but how can we advance along a "sound and fast" development path? The establishment of economic zones in Chengdu and Chongqing,Guanzhong and North Bay has opened up new possibilities and expectations for western China's economic development. 展开更多

In general, it can be argued that institutional framework a country or region designs plays a significant role in crafting, applying or even success of public policy. Drawing lessons from how Asia exploited the developmental state's concept by designing institutions which targeted key public policy areas such as education, health, domestic savings, and rural development, or aligned infrastructures such as roads, transport and ports, to drive economic development. The paper explores how this approach can be applied in sub-Saharan Africa (or individual countries). The objective is to extricate constant factors impacting development both in ahistorical and atemporal terms. The investigation is guided by the key question: whether quality of institutions and institutional analysis can help explain development failures in Africa? Hence, on one part, it probes institutions, institution-making, public policy making and what uniquely the Asian developmental state did that can help illuminate institutional role in policymaking and application. In pursuing this objective, the paper is cognisant of the question by Brousseau et al. asked, regarding generalizability of institutional capabilities, "If growth-enhancing institutions are identified in a specific country, can other countries learn from and transplant these". The investigation concludes that in public policy and development strategy-making institutions do matter as they delimit or even help create possibilities necessary for development and its sustenance, and to a certain extent, they are the vital constant (factors) that explains development differentiations in different geographic spaces or time periods. 展开更多

A review of the literature indicates that,currently,Ethiopia is now beyond the bounds of fragility.The purpose of the study was to investigate whether Ethiopia was experiencing fragility.After a review of the literature on fragility,a theoretical framework lens on fragility was developed to empirically test Ethiopia’s current condition.A longitudinal analysis indicates that before 2018,Ethiopia was regarded as the central economic engine of sub-Saharan Africa.However,as the current regime reversed Ethiopia’s developmental state model and moved to follow a neo-liberal model,Ethiopia’s economy has gradually diminished.More specifically,during the current regime,Ethiopia has experienced a decline in its Gross Domestic Product,faced rampant unemployment,and encountered an increase in inflation.Its foreign exchange currency reserves have declined below the three-month threshold of hard currency required for a country to import goods and services,and its external debt has extended beyond the country’s GDP.By encouraging armed conflict and widespread insurgencies,the current regime has caused social tension and deep humanitarian crises in Ethiopia-resulting in devastation of health and school facilities and causing more than five million Ethiopians to be displaced.Finally,failing to provide leadership to his people,the current regime in Ethiopia has willingly allowed the incursion of Ethiopia’s sovereignty by foreign forces.The conclusion of the study is that,when observed through the lens of fragility using a longitudinal framework,currently,Ethiopia has traversed beyond fragility and seems to be heading toward balkanization. 展开更多

Language acquisition is a system with four components: language development, academic development, cognitive development and sociocultural development. Based on this theory, Chinese students in the United States are studied from three perspectives: linguistically, culturally, and social psychologically. It indicated that, to help Chinese students develop their English performance and cultural appreciation in this diverse world, the profession of English teaching in China should cover a variety of domains, including linguistic, cultural and psychological input. Both American and Chinese education can benefit from this special group of Chinese students if they can be better understood, and used as a bridge between China and U. S. cultural and academic exchange. In the meantime, the mirror held up to the Chinese students in these perspectives reflects not only who they are but also who they can become. 展开更多
