Geographies of relational coordination in venture capital firms

ABSTRACT

Venture capital (VC) firms are crucial actors in entrepreneurial ecosystems. Through the development towards a digital economy, they have gained further relevance, which caused the VC industry to diversify in terms of business models. This article offers a new heuristic to study the VC industry by developing a classification of VC firms. By drawing on a framework of different dimensions of relational distance in investment relations, different types of relational coordination are identified by comparing VC firms in Germany. The types of VC business models are found to produce relational geographies of investing as they relate with their portfolio startups in different ways. A relational perspective on VC thus provides the opportunity to step beyond pure territorial approaches on VC.     

旅游乡村治理演变机理及模式研究——陕西袁家村1949-2019年纵向案例研究

乡村治理是乡村研究的显题，研究发展新兴产业的乡村治理对振兴乡村意义重大，但较为匮乏。本研究基于对陕西省袁家村1949—2019年的治理历程的梳理，探讨旅游乡村治理的演变机理以及成功模式。研究发现：①中国乡村治理经历“宗族自治”、“寡头他治”两个阶段，良性的治理模式需要内生动力和外生要素的共同作用。②旅游乡村治理的主体更加多元、目标更聚焦于集体发展、机制更追求正义、系统更不稳定。③有效的旅游乡村治理需要构建“集体共治”模式和动态开放的治理系统，注重社区精神的约束力，促进旅游乡村发展健康可持续。     

The Power of Models in Planning: The Case of DaisyGIS and Nitrate Leaching

Spatial deterministic simulation models such as DaisyGIS are increasingly being used for decision‐making in European planning. In Denmark specifically, there is an increasing interest at the regional level to use DaisyGIS as an administrative tool. There are, however, uncertainties associated with the use of these deterministic models, partly due to the spatial variation in input parametres. This study evaluates the use of DaisyGIS for nitrate leaching assessments based on nitrate leaching experiments carried out at the Marbjerg experimental site at Roskilde University. The study includes geostatistical analysis of soil and hydraulic variables and the use of remote sensing for deriving spatial information about the Leaf Area Index. It is found that the model predicts nitrate leaching well when using site‐specific input data but it is quite sensitive to the parameterization of carbon, the C/N ratio and variations in the Leaf Area Index (LAI). With the increasing use of Daisy in the counties, there is a need to find better ways of handling uncertainties in model output which can be used by decision‐makers and to study further the impact of spatial LAI assimilation on catchment scale nitrate leaching processes.     

租购同权”政策对学区房溢价的影响研究——基于空间特征价格模型的广州实证

在公共服务对住房市场的影响研究领域，学校质量的资本化效应一直是重要话题。本文借鉴边界固定效应思路，使用广州市2016和2019年136所重点小学周边学区房与相邻非学区房的配对面板数据，利用空间特征价格模型定量测度了不同质量等级教育资源的资本化效应，使用双重差分模型检验了“租购同权”政策对重点小学学区房房价和租金溢价的影响。研究结果表明：①广州市教育质量已部分资本化于住房价格和租金之中，且教育资源越优质，资本化程度越高。②“租购同权”政策的实施，并未带来学区房房价和租金溢价的显著变化。③“租购同权”政策对不同质量等级的重点小学学区房房价影响存在异质性，政策实施后省级重点小学的学区房溢价上升，区级重点小学的学区房溢价下降。④“租购同权”政策对于不同区域重点小学学区房房价和租金溢价的影响无显著差异。本文的研究结论可以为制定教育资源供给与配置的均衡化和公平性政策提供参考。     

传统法治文化对当前地方法治政府建设之启发

中国传统法治文化是中华几千年国家治理的智慧结晶,在不同历史时期具有不同的文化特点,也存在自诞生之初就无法克服的不足之处,如强调人治、维护宗法、重刑轻民等。但是,传统法治文化有很多值得我们吸收改进的有益之处,尤其在教民、治吏与息诉这三点上,对当前地方法治政府建设有着重要的借鉴意义。本文结合包括福建本地的一些法治实例,阐述传统法治文化的特点和不足,以"从严治吏"为重点,对如何更好的建设地方法治政府提出几点个人思考和建议。     

Cellular Automata for Studying Historical Spatial Process of Traditional Settlements Based on Gaussian Mixture Model: A Case Study of Qiaoxiang Village in Southern China

ABSTRACT

The spatial evolution of traditional rural settlements is a natural process that occurs without professional development planning. With rural spatial organization now being stimulated by China’s economic structure adjustment, making top-down plans match bottom-up spatial principles is important for the continuity of rural communities. In this research, a Cellular automaton based model was introduced to describe the historical spatial rules of rural settlements based on a traditional village in Southern China. In order to reproduce the rural spatial characteristics and laws that were close to the actual situation truthfully and distinctly, in this model, we refined the growth process into three cyclical steps, and used a Multivariate Gaussian Mixture Model for the evaluation of spatial transition potential. Through historical simulation, evaluation of the current status, and future spatial predictions, results showed that: (1) the growth during the whole spatial process maintained logical consistency for optimal selection; (2) certain houses in the southeast region should be carefully protected as a core living culture exhibit, while the best utilization of other homes should be considered; and (3) the most probable region of growth for tourist services or new housing estates is scattered along the river in the central area of the village.     

Ödemiş-Dereuzunyer: Architectural Features of a Rural Settlement to Be Submerged by Dam Waters

ABSTRACT

The village of Dereuzunyer located in the Rahmanlar Valley of the Küçük Menderes Basin is a settlement that is a natural extension of a topography shaped by a joint contribution of culture and nature. It has preserved the authenticity and integrity of its traditional rural fabric and gives detailed information about the architectural approach, building technology, construction techniques, landscape features and traditional craftsmanship of past rural life. While some of the cultural assets in the settlement containing detailed information about the rural lifestyle of the past have survived to date despite the harsh natural conditions, the remainder have been neglected, become dilapidated, and fallen into ruin over time due to lack of maintenance by the local people because of rumors about the possible dam project and expropriations in progress. After completion of the Rahmanlar Dam in 2019, the cultural landscape values of Dereuzunyer will be lost irretrievably. This article aims to make a contribution to creating awareness about avoiding such losses, not only by introducing the non-renewable values of Dereuzunyer, by documentation of its historical development, its traditional architecture, its traditional building types, its construction techniques, and its plan and façade features, but also by promoting and interpreting its lost cultural heritage.

Historic Barrel Vaults Undergoing Differential Settlements

ABSTRACT

A principal reason of damage in historic masonry vaults consists in relative displacements of the vaults’ abutments. Excluding the case of seismic-induced damage, cracks are often produced by differential settlements generated by the lateral wall instability or soil degradation (e.g., due to stress concentrations, non-uniform soil stratigraphy, flooding phenomena etc.). When dealing with historic vaults, the effects of long-term deformation processes cannot often be linked directly to causes, which may also be unknown. In this article, the effects of differential settlements on historic masonry barrel vaults are investigated. An efficient 3D contact-based model was developed to reproduce experiments on a scaled pointed barrel vault (representative of a typology of late-medieval barrel vaults in Scotland) under non-uniform differential settlement. First, the numerical model is used to simulate the experimental campaign, achieving good agreement in terms of crack pattern (longitudinal shear) and transverse-longitudinal deformation profiles. Then, further analyses are carried out to gain insight on the effects of several plausible uniform and non-uniform settlement patterns on representative historic barrel vaults. Various settlement configurations were analysed and complex failure patterns observed. This study could help analysts in understanding the nature of on-going deformation process in historic masonry vaults and engineers in the design of strengthening strategies.     

Integrating Local and Regional in Pre-Contact Hawaiian Agriculture at Kahuku,Hawai‘i Island

ABSTRACT

The agricultural systems of the Hawaiian archipelago were some of the most intensive in the Pacific and this scale of intensity is well illustrated by the large agricultural landscapes of leeward Hawai‘i Island. Previous research in the area has centred on understanding the relationship between agriculture, political process, and large-scale environmental conditions. Much of this research has been oriented at the regional level, privileging discussion of elite management and oversight, with only limited investigation exploring farmer-centric adaptation at local scales. In this paper, we assess the integration of local and regional processes in Hawaiian agriculture using recent paired archaeological and ecological data from the Ka‘ū Field System as a case study. We demonstrate the presence of both general patterns previously identified in the archipelago and particular adaptations to the local environment of Kahuku ahupua‘a. In particular, we highlight targeted infrastructural developments that allowed for cultivation of what would otherwise be a difficult cultivation medium within the confines of a larger, likely regionally organised, field system constrained by general soil biogeochemical thresholds. We argue that such investigations provide an increased understanding on how these large-scale agricultural landscapes were formed by integration at multiple social and spatial scales.
