清代化平川厅厅治溯源研究

与现代论著主要论述宁夏泾源县的建置沿革不同,本文主要从地理学的角度分析泾源县治所从宋到清迁徙、废弃和复置的原因。北宋陇山东西两侧道路的变迁、金代陇山川原开发和陕西地缘格局转变、元明陕西政治交通格局变化以及清代安置回民,都对泾源县治所的变化产生了影响。

Climbing the Ladder? High-Technology Export Performance in Emerging Europe

A British economist examines the development of high-technology industrial exports across the emerging Europe region over the past two decades. After arguing that the development of high-technology capabilities is a key component of economic development, he presents an original index of high-technology industrial export performance that is used to describe patterns of high-technology exports across emerging Europe. When these developments are placed in comparative perspective, it becomes evident that although the countries of emerging Europe have made considerable progress in increasing across-product sophistication of exports and in increasing across-product diversification, most have been less successful in improving levels of within-product sophistication. For emerging Europe and other low- to middle-income countries elsewhere, this will remain a key challenge for the future.     

Sustaining China's Economic Growth: New Leaders,New Directions?

An American specialist on the economy of China assesses the options and obstacles the country's new leadership will face as it attempts to sustain the current economic growth trajectory in the future. Putting the current situation in historical context, the author first reviews the reforms leading up to the agenda advanced by the previous leadership team (led by Hu Jintao) and then examines the health of China's economy in late 2012 (a situation she argues is characterized by the exhaustion of three key drivers of growth). The paper advances the thesis that further reforms and improvements in technology will be essential to sustained growth, and that additional reforms will be necessary before sustained innovation can take root. As signs of successful further reform going forward, readers are advised to look to increased private-sector legitimacy, a decline in state-sector monopoly power, and strengthening of legal foundations for reform policies.     

Universities in inclusive regional innovation systems: Academic engagement and uneven knowledge use in Brazil

The purpose of this paper is to spatially and regionally examine academic engagement within Brazil, identifying patterns. Moreover, our investigation can contribute to a better understanding of how knowledge can be turned into a tool to fight regional inequality. We depart from two hypotheses: first, universities situated in peripheral regions interact more with companies from relatively more dynamic regions, and second, in the absence of industrial knowledge demand, universities tend to collaborate more closely with a diverse range of stakeholders in the region. To evaluate these hypotheses and find empirical evidence, we consider 4497 research groups and 4603 nonacademic organizations as “nodes” connected by 8830 collaborations throughout all Brazilian regions. Social network tools are used to illustrate the spatial and regional dimensions of academic engagement more accurately. The results show that academic engagement is not regionally homogeneous, demonstrating essential differences regarding local nonacademic partnerships. Innovation policies, which encourage only university–firm interactions, perpetuate regional inequality.     

Playing outside the box – on LEGO toys and the changing world of construction play

This article deals with three major instances in the history of the LEGO Company. First, it investigates the transference from wood to plastics as the main material used in creating LEGO toys, and also the innovations in plastic molding machines that influenced the interlocking mechanism of the LEGO bricks. Second, this article deals with a rather unfortunate episode from the LEGO history, namely, the period between the late 1990s and the early twenty‐first century when the LEGO Company felt the need to extend its brand image through diversifying its product range. Unfortunately, this led to a confusing, rather than a strong brand image and resulted in heavy financial losses in 2003 and 2004. Third, this article looks into recent attempts by the LEGO Company to bring the fans into the company in order to revive the LEGO brand and its products. This part focuses on Mindstorms 2.0 and Mindstorms NXT, especially, in order to illustrate the increase in user involvement in LEGO product development.
