曼春满村寨民族旅游中村民社会角色变化调查研究

民族旅游是云南省的主体旅游之一，在民族旅游中，云南农村广大村民的社会角色在许多方面发生了较大的变化。西双版纳傣族自治州景洪市勐罕镇曼春满村寨旅游景点旅游开发价值高，景点开发较早，旅游业发展较快，经历了从起步到较成熟的4个阶段。村民在参与旅游业的过程中，传统产业被放弃或减少；家庭经济收入逐步转变为以旅游业为主；家庭消费更多地投入精神产品；村民人际关系中融入了经济因素和竞争意识；夫妻家庭劳动分工中，从事旅游业的妻子已基本不干农活和少做家务；以儿媳为代表的女性在家庭中的地位空前提高；村民思想意识等方面受到外来者的影响，拉近了村民与城市居民的距离。     

SOCIAL THEORY AND THE FUTURE OF URBAN GEOGRAPHY*

Three themes that seem likely to be influential in the near future have recently characterized the work of geographers using social theories as the basis of their explanations of urban phenomena. They are (1) the debates about structure and human agency. (2) the claims of feminists about the analytical significance of the social construction of gender roles, and (3) the demand that we now use our social theories more actively to explain experienced reality. In continuing our use of social theory in urban geography, we must prevent its marginalization as one specific substantive topic; the alternative epistemologies of this type of work can guide new interpretations of every substantive issue in urban geography.

Risks of shifting baselines highlighted by anecdotal accounts of New Zealand's snapper (Pagrus auratus) fishery

Anecdotal data sources may constitute an important component of the information available about an exploited species, as record keeping may not have occurred until after exploitation began. Here, we aimed to fill any gaps in the exploitative history of the sparid snapper (Pagrus auratus), using social and historical research methods. Social research consisted of interviews with recreational fishers, focusing on the most and largest snapper they had caught. In addition, the diary‐logs of two recreational fishers were analysed. Historical research consisted of investigation of old books, photos, archives and unpublished sources unconventional to fishery science. Interviews with fishers demonstrated no or weak trends in snapper abundance or size, and were likely impeded by a lack of ability to detect change in a fish stock that may still be considered abundant. The fishers’ perception of change, however, largely reflected recent experiences (last c. 10 years), when biomass is understood to have increased, and mostly did not consider experiences before the 1980s. Alternatively, diary‐logs of fisher catch rates produced a pattern that matched formal stock assessments of snapper biomass, suggesting declines in abundance up until the 1990s and an increase in biomass after that time. Historical research, although more qualitative, had the ability to investigate periods where formal records were not kept and described a fishery vastly different from the current one. Snapper were easily caught, in great abundance and in unusual locations. Localised depletion of snapper was first noticed in the early 20th century, despite spectacular catches of snapper occurring after that time. Snapper behaviour was also likely different, with visual sightings of snapper by onlookers a common occurrence. Although predictions from stock assessment models are consistent with that of the anecdotes listed here (i.e., high biomass in the past), these anecdotes are valuable as they explain lost biomass in a perspective meaningful to all. This perspective may be valuable for managers trying to consider the non‐financial value of a shared fishery but, if unrecognised, represents a shifting baseline.     

面向治理的地理学发展刍议

“四个面向”（面向世界科技前沿、面向经济主战场、面向国家重大需求、面向人民生命健康）已成为新时代中国科学发展的指针。治理是一个反映“四个面向”的国际前沿研究领域,也是地理学和其他学科研究的焦点。围绕地理学如何应对治理这一关键问题,基于人地耦合的理念,系统梳理国内外地理学进行治理研究的轨迹与特点,从价值、思想、方法、技术4个维度发掘面向治理的地理学发展路径,紧密联系地理学发展动态及治理现代化的实践,从基础研究、平台建设、人才培育3个方面提出发展策略。提升中国地理学在国际治理研究中的影响力,促进地理学与其他学科的交叉融合,将自然与人文有机结合的理念应用于社会治理,增进居民福祉,并服务国家战略和区域可持续发展。     

The Econo-techno-social Design of Invasive Animal Management: costs and benefits or beneficiaries and benefactors?

This paper examines invasive animal management institutions, using theories at the interstices of anthropology and geography, to question current approaches to management based on neoclassical and neoliberal economic rationales. I present an analysis of two feral pig management regimes in Far North Queensland, Australia: (i) bounty systems of payment for feral pig control; and (ii) a community-based feral pig trapping program. I show how these management methods reshape important social and cultural processes through their overlapping technological and economic elements. On the basis of this analysis, I propose a conceptual framework for invasive animal management planning that incorporates a beneficiary–benefactor analysis alongside cost–benefit analyses. I argue that ecological-economic theories of pest management may be usefully enhanced by addressing the links between economic and social behaviours.     

基于上市公司网络的长三角城市网络空间结构研究

公司内部网络研究是当前城市经济网络研究的重要内容.本文利用2005、2010年长三角A股上市公司企业网络数据库,运用社会网络分析方法、位序—规模分析法等,分析了2005、2010年长三角城市网络空间结构演变及其主要影响因素.研究发现:①长三角上市公司总部沿沪宁—沪杭—杭甬Z字形轴线集聚,从一主(上海)二副(杭州、南京)三中心向一主(上海)三副(杭州、苏州、南京)四中心空间结构演变;苏州超过南京成为第三大企业总部集聚中心.②长三角城市网络核心—边缘结构整体延续,Z字形轴线城市维持核心地位,具备强大的网络权力与威望.③长三角城市网络除等级扩散、邻近扩散等特征之外.还具有明显的行政地域性.主要体现在省会南京、杭州分别成为江苏、浙江省内外上市公司子公司的重要据点;尤其是南京凭借省会优势,中心度仍然高于总部职能较强的苏州.④在长三角经济一体化背景下,跨行政地域性的联系有所加强,特别是上海、苏南向苏中、苏北的扩散明显;浙西南仍是网络相对封闭、孤立的地带,中心度相对较低.⑤行政等级和区划,市场容量等是长三角城市网络空间结构的主要影响因素,而到上海高速公路时间距离、劳动力成本和土地成本的影响在统计上未通过显著性检验.

复杂网络中多话题信息传播仿真研究

传统复杂网络话题传播研究,重点关注的是单个话题在网络中的传播,较少考虑多话题之间的相互影响因素。论文分析舆论传播过程中多个话题之间的竞争关系对话题传播的影响机制,建立基于复杂网络的多话题信息传播模型。通过对模型仿真实验及其结果分析表明,当引入个体信息环境影响因素后,一个话题的影响力大于舆论话题环境中其他话题的平均影响力,才会有较大概率影响到更多个体,否则只能在小范围内传播;个体对于话题记忆能力的变化在不同网络中会产生不同影响,在随机网络和BA网络中,人们对于话题的记忆越深,其传播的影响范围越大,而在规则网络和小世界网络中,较小的记忆长度能够让话题传播影响力更大;同时,在具有社群结构的网络中,度大的节点并非会一定会更多的参与某一话题的传播,因为度大的节点有更大概率获得更多的话题。
