WORKINGS OF THE MELTING POT: SOCIAL NETWORKS AND THE EVOLUTION OF POPULATION ATTRIBUTES*

ABSTRACT This paper links the two nascent economic literatures on social networks and cultural assimilation by investigating the evolution of population attributes in a simple model where agents are influenced by their acquaintances. The main conclusion of the analysis is that attributes converge to a melting‐pot equilibrium, where everyone is identical, provided the social network exhibits a sufficient degree of interconnectedness. When the model is extended to allow an expanding acquaintance set, convergence is guaranteed provided a weaker interconnectedness condition is satisfied, and convergence is rapid. If the intensity of interactions with acquaintances becomes endogenous, convergence (when it occurs) is slowed when agents prefer to interact with people like themselves and hastened when interaction with dissimilar agents is preferred.     

SOCIAL NETWORKS AND CROSS-CULTURAL INTERACTION: A NEW INTERPRETATION OF THE FEMALE TERRACOTTA FIGURINES OF HELLENISTIC BABYLON

Summary.   In the study of the Hellenistic period in Babylon, cross-cultural interactions between Greeks and native Babylonians have been primarily interpreted using colonialist theories of Hellenisation, domination, and cultural isolation. This paper finds, however, that such theories cannot adequately explain the types of cross-cultural combinations seen in the archaeological record of female Hellenistic Babylonian terracotta figurines. The forms and functions of these terracotta figurines were substantially altered and combined throughout the Hellenistic period, resulting in Greek-Babylonian multicultural figurines as well as figurines that exhibited new features used exclusively in Hellenistic Babylonia. In order to facilitate a greater understanding of the full complexity of these Greek–Babylonian interactions, a new interpretation of cross–cultural interaction in Hellenistic Babylon is developed in this paper. This Social Networks model provides an alternative framework for approaching both how a hybrid material culture of terracotta figurines was developed and how Hellenistic Babylon became a multicultural society.

城市更新中社会网络的保存和发展

本文介绍了城市居住社区中社会网络的内涵和意义,并阐述了以往几种城市改造形式对社会网络产生的影响。进而探讨实现社会网络保存和发展的城市更新有效形式,对城市更新中社区自建和渐进式小规模更新改造等形式的经验进行了回顾。提出应运用渐进式小规模有机更新改造,并借鉴规划师与居民双向交流、共同合作的经验,实现居住社区中社会网络的发展完善。最后本文以盱眙旧城改造为例,分析了城市更新改造中社会网络保存和发展的可行性。     

A SIMPLIFICATION AND GENERALIZATION OF THE EXCLUSION THEOREM: A TECHNICAL NOTE

Several researchers have proven that for the integrated production-location problem on the Weberian triangle, intermediate points on the edge of the triangle can never be optimal locations. Authors of previous proofs of this result have used cumbersome trigonometric arguments. We present a much simpler algebraic proof of the result, and present it in terms of the more general n -input model, where the feasible location space is a convex polygon rather than a triangle. In addition, the result generalizes immediately to other cases, such as (1) multifacility production-location problems, (2) stochastic versions of one-facility and multifacility production-location problems, and (3) comparable pure location problems (e.g., the Weber problem).     

解析信息社会流动空间的概念、属性与特征

伴随着20世纪90年代以来的数字技术革命,围绕信息而产生的概念被广泛纳入到了城市与区域空间研究框架中。流动空间是全球化进程中在信息技术的推动下产生的一种新的空间形式。信息技术、经济和空间的共同作用改变了传统的时间、空间和距离的概念,产生了全新的流动空间场。为了在城市与区域规划中更好地理解与应用流动空间这一概念,在把握国内外相关研究的基础上,我们总结出流动空间的概念,认为其具有实体空间与虚拟空间的二元属性,提出流动空间具有流动性、共享性、高时效性、空间弹性和高级网络性五大特征。在信息时代,对于流动空间的概念、属性与特征的研究强调了流动空间作为区别地方空间的一种新空间形式的内涵,突显出信息技术改变我们居住、生活空间的同时,将使我们主动地迎接空间转变的挑战。     

PERCEIVING COMMUNITIES: EXCHANGE, LANDSCAPES AND SOCIAL NETWORKS IN THE LATER IRON AGE OF WESTERN BRITAIN

Summary.   In recent years British Iron Age studies have focused on regionality whilst critiquing the hierarchical model of Iron Age society. Despite the success of these approaches there has been little detailed replacement of previous social models with an understanding of how Iron Age societies worked. Looking at the later Iron Age of western Britain this paper combines examination of the exchange of material culture alongside study of the landscape to explore the nature of Iron Age communities. It is argued that Iron Age societies in the region used material culture to construct and maintain social relationships, while using visual landscape references allowed groups to engage in larger perceived communities.     

SOCIAL SCIENCE AND SOCIAL POLICY: ROLES OF THE APPLIED RESEARCHER*

Research on policy impact has increasingly focused on the practical application of social science research. This paper outlines four roles—substantive expert, information processor, change agent, and scholar—which have helped to increase the potential usefulness of our research while maintaining linkages to the academic community. This paper suggests the general nature of these roles and suggests specific implementation strategies, which need to be pursued as an early and continuing aspect of the research enterprise. Balancing these multiple roles presents several analytical and ethical difficulties, but helps to establish credibility in both the scientific and policymaking communities.     

人口自身再生产与生态环境的拓扑探析

本文运用耗散结构和自组织理论,从物质循环和能量转化方面,剖析了生态环境与生态系统的拓扑关系,进而从理论深层探讨了人口自身再生产与生态环境之间的相互机制与演绎规律。文章认为再建生态平衡和人与自然和谐的基础在于有效地控制人口增长和寻求合宜的经济发展模式,并通过技术进步改善和保护生态环境。     

基于企业网络视角的城市网络研究进展与展望

随着生产分割程度的不断加深,企业网络空间增长已经成为城市网络生长发育的重要驱动力量。近30年来,基于企业网络视角的城市网络研究日益增多,在链接关系及时空过程、价值生产空间格局、外部经济及其空间差异、规划实践及治理模式四个方面取得了重要进展。本文在梳理城市网络发展脉络的基础上,从多维视角提出了基于企业网络视角的城市网络理论体系研究框架。总体来看,基于企业网络视角的城市网络研究还处于起步发展阶段。围绕完善理论体系建设,未来研究应着力在5个方面取得进展：城市网络分析技术方法的发展完善、城市网络多维度时空过程的综合比较研究、城市网络发育过程的微观机理解析、城市网络演化模式理论模型研制、城市网络的治理模式和政策框架研究。

社会阶层化与城市社会空间的发展及其与城市娱乐业的(空间)关系

基于学术界共识的后工业化大城市社会空间中产阶层化的理念,本文首次提出社会阶层化的概念并指出社会阶层化主要研究在社会阶层的生活行为扩散和变化规律下,所构建的城市日常居住社区体系和日常生活行为场所体系的时空模式,以此探讨城市社会空间结构的变化。研究认为不同城市发展阶段其对应有不同主导阶层的社会阶层化空间结构。进一步从解构城市社会空间结构的演化动态角度,研究不同社会发展阶段下,社会阶层化与城市娱乐产业的对偶空间结构关系。     

社区人文社会环境对汶川地震移民社会适应的影响——以北川县为例

对汶川地震移民来说,社区人文社会环境直接影响他们的社会适应状况。本文基于调研数据,构建模型来探究社区人文社会环境对移民社会适应的影响。研究表明：社区人文社会环境下的16个单一指标,仅"社区治安"和"干群关系评价"对移民的社会适应状况有显著影响;但16个单一指标集成的4个综合指标-"配套设施"、"邻里关系"、"干群关系"和"观念习俗",却均对地震移民的社会适应状况影响显著,并且除"观念习俗"与移民的社会适应程度呈弱显著的负相关关系外,其他3个综合指标与移民的社会适应程度都呈强显著的正相关关系。     

SOCIAL NETWORKS AND TERRITORY IN A COMMUTER VILLAGE, BOND HEAD, ONTARIO

SOCIAL NETWORKS AND PLACE
Below the level of formal organizations, but above that of individual behaviour, there exists a weblike mesh of relationships between households. We are all aware, intuitively, of social networks. They are the old-boys networks, cliques, alliances, friendships, acquaintanceship chains, and kinship groups in which we all participate. Many, perhaps most, decisions taken by individuals are mediated through social networks. Networks are, as well, located in geographic space. In this paper I shall look at the concept of social networks and then use the concept to examine a small settlement in the Toronto hinterland.
