The role of university Knowledge Transfer Offices: Not just commercialize research outputs!

While there is a prevailing rich body of studies on the role of university knowledge transfer office (KTO) in the commercialization process as part of the Third Mission, research on its role in community engagement activities is relatively neglected, even as funding agencies and policy makers conceive these as instrumental to sustaining social and economic development. This article focuses on the role of university KTO in supporting, facilitating or undertaking Third Mission community engagement activities. Drawing on data from the annual Higher Education Business and Community Interaction survey for the years 2007–2012, this paper empirically explores the relationship between a range of Third Mission activities by university KTO and performance of three key business-community services – provision of consultancy, provision of continuous professional development courses (CPD), and leasing of facilities and equipment (FE). It emerges that the routines of developing strategic plan and creating spin-off are positively associated with all types of community knowledge transfer (CKT) activities. Further, the routines of establishing partnerships with local and regional bodies, and licensing are positively related to CPD and FE, respectively. The article is concluded with implications for theory, practice, policy, and suggestions for future research.     

The State as Both Regulator and Player: The Politics of Transfer of Development Rights in China

The conventional argument that the introduction of transfer of development rights (TDR) shifts the power of land use regulation from the state to the market is increasingly under challenge. In China, the state's grip on land is reinforced through TDR, in which the state is both regulator and player. This state-dominated form of TDR affects China in three ways. First, competing aspirations of different scales of government complicate how TDR is implemented. Although the central state promotes TDR to maintain a national balance of arable land, some local states instrumentalize it to expand their landed basis of accumulation. Secondly, TDR tends to benefit the state but not its people. It may increase the fiscal income of the sending government and lessen the land shortage of the receiving government, but sometimes at the expense of the interests of land users without land ownership. Thirdly, given the state's deep involvement in TDR programs, the key for China's TDR to protect arable land lies not so much in clear property rights or a fully fledged market as in effective checks and balances regarding the state's powers over TDR. These three observations attest to the embeddedness of TDR in the local political economy.     

融合反距离加权和矩阵填充的位置指纹库构建

为解决位置指纹定位在离线阶段构建位置指纹库时耗费的人力和时间成本较大，构建指纹库效率低和利用空间插值法构建的指纹库精度不高的问题，提出了一种融合反距离加权和矩阵填充的位置指纹库构建算法。该算法仅需人工采集定位区域内少量参考点的接收信号强度值用作信标点指纹信息，结合反距离加权算法特性计算出次信标点指纹信息，根据位置指纹库数据矩阵的低秩性，应用奇异值阈值矩阵填充算法构建出位置指纹数据库。仿真实验结果表明，所提算法有效降低了矩阵填充算法构建位置指纹库所需的人工和时间成本，构建出的位置指纹库定位性能优于反距离加权和克里金空间插值法，接近传统人工采集法，显著地提高了位置指纹库的构建效率。     

双平行线阵的快速一维DOA估计

针对传统子空间算法需要进行特征值分解或奇异值分解等复杂计算的问题，提出一种双平行线阵（Double Parallel Linear Array,DPLA）的快速一维波达方向（Direction of Arrival，DOA）估计算法。算法通过处理互协方差矩阵的第一列元素构造出等效的噪声子空间，再通过求根MUSIC（Multiple Signal Classification）算法得到DOA估计，有效避开了特征值分解或奇异值分解，降低了计算复杂度，提高了运算速度。仿真结果表明，该算法在提高了估计精度的同时减少了估计时间。     

The challenge of Chinese state‐affiliated multinationals in benefiting from foreign subsidiary knowledge transfer: A criticism of light‐touch integration

Acknowledging the sharp growth of Chinese state‐affiliated multinationals and their strategic asset‐seeking investments abroad, this study investigates the effects of headquarters' home‐country political ties on the multinational‐wide benefits gained from subsidiary knowledge transfer in Chinese multinationals. It also looks at how these effects are mediated by organizational distance and social integration between headquarters and subsidiary. Based on a survey of 177 subsidiaries of 99 Chinese multinationals, we find that headquarters' political ties trigger organizational distance and hinder social integration between headquarters and foreign subsidiaries and these, in turn, hamper the potential benefits that Chinese multinationals derive from subsidiary knowledge transfer. This study identifies new challenges related to political ties and light‐touch integration in gaining benefits from subsidiary knowledge transfer.     

我国耕地保护政策研究：基于背景、效果与未来趋势

［目的］我国耕地保护政策对保护耕地、保障粮食安全具有重要意义。研究我国耕地保护政策出台的背景及前后关系、相同政策在不同区域内的执行效果差异，能够为更针对性地提出政策建议提供参考。［方法］主要运用了资料分析和定性描述的方法，首先按照耕地保护政策内涵划分为5个阶段，其次从时间、空间两个尺度，判断了耕地保护政策的数量、质量保护效果差异，最后提出了未来政策出台的方向和趋势。［结果］时间尺度上：1986年、1997年、2004年出台的政策对耕地数量保护的成效明显； 2014—2016年耕地质量保护效果略优于2009—2014年； 目前数量保护成效较好，但质量保护远未达到要求。空间尺度上：耕地数量保护效果西部地区最好，东北地区次之，中部地区优于东部地区； 耕地质量保护效果中部地区最佳，东北地区次之，东部地区优于西部地区。［结论］未来政策可向规范补充耕地全国统筹、完善耕地质量保护法律体系、调动农户保护耕地积极性等方向发展。     

Theoretical analysis and model design of search for ecological conservation redlines based on the sensitivity assessment of ecosystem services

Most small-scale social economies are characterised by their deficiency, lack, and/or difficulty in matching natural data. Against this backdrop, this paper builds a relatively uniform theoretical framework and designs a more economical and objective method for demarcating ecological conservation redlines (ECR) based on sensitivity assessment of ecosystem services. The results show that the sensitivity assessment model designed in this study can identify sensitive zones effectively, and that the ECR in Hubei Province are well within the sensitive zones so identified. The delimited areas based on the sensitive assessment of ecosystem services have great similarities (95%) with the actual ECR areas in Hubei Province. The most ecologically important functional zones (EIFZ) can also be identified using the regional ecological sensitivity coefficient. When the threshold of EIFZ is set higher, the probability that it falls within the ecologically sensitive areas is greater and the ECR delimited by the method proposed in this study will be more reliable. Theoretically, the delimitation of ECR can be inserted at any evaluation level with a grid resolution higher than that of the land use data, which can be used as a supplement to the ECR delimitation method in ecology or geography.     

Spatial and temporal analyses of potential land use conflict under the constraints of water resources in the middle reaches of the Heihe River

With the rapid urbanization in China, land resources are becoming increasingly scarce. Identifying and resolving land use conflict is essential for reasonably using land resources and achieving land sustainability. Taking the middle reaches of the Heihe River as an example, we included the constraints of local water resources to construct a multi-criteria evaluation system for assessing land use competitiveness in 2000 and 2015 based on land use, socio-economic, and nighttime light data. By comparing the competitiveness of cultivated land, construction land and ecological land, we then derived the spatiotemporal patterns of potential land use conflicts. Actual land use changes supported the hypothesis that land use tended to convert into the type with higher competitiveness at areas with intense conflict, which better indicated that our assessment model was effective. The results showed that the potential land use conflict was more acute in the central and northwest but weak in the southeast and northeast, and its pattern showed a significantly positive spatial autocorrelation. The conflict between cultivated land and construction land was most prominent and mainly occurred in the transitional zone from urban to rural areas. Rapid urban development and water shortage were the main causes of the potential land use conflict. Assessing land use multi-functions and making a tradeoff among ecological, economic, and social services will be an effective way to guide future land use to solve land use conflict. Our research provides scientific evidence for sustainable land use planning and management in the arid areas.     

土地经营权债权属性之再证成

研究目的:证成现行法语境下土地经营权的债权性质,为土地经营权在新《农村土地承包法》和《民法典》中的体系化阐释与衔接奠定基础。研究方法:比较分析方法、原理论证和法释义学。研究结果:"用益物权说"违背定限物权生成之法理,将造成虚化土地承包经营权之困境。"权利用益物权(次级用益物权)"进路亦存虚化客体权利之弊,德国"次级地上权"经验无法证明其可行性。参酌德国民法中用益物权之行使移交制度,土地经营权之债权定性既与现行规范解释相契合,在学理推导和制度承接方面亦具正当性。研究结论:现行法中的土地经营权统一为债权属性,"用益物权说"和"债权物权二元说"无法成立。
