农村社区农户互动效应的定量评估——来自河南省杞县孟寨村的实证 总被引：1，自引：0，他引：1
信息流动会使农户产生互动学习效应,进而影响农户的农业生产率。基于河南省孟寨村第8小组农户的普查,获得有关农户亲戚、邻居和与之地块邻近农户的社会经济特征和大蒜产量的信息,对这些群组内部的互动学习效应进行检验,并识别不同类型的互动效应。结果表明:内生互动效应仅存在于亲缘群组;情境互动效应存在于地邻群组和邻里群组,但在两个群组中存在一定的差异;关联效应在三个群组均存在,与亲缘群组相比,邻里群组和地邻群组中关联效应更大,但在亲缘群组中,关联效应远小于内生互动效应,在邻里群组和地邻群组中也远小于情境互动效应。研究结论对国外学者的发现进行了修正。这种理论研究具有重要的政策含义。 相似文献

Abstract Computer technology has a rich history in geography education. The Internet represents the latest in technological advancements that continue to have important effects on geography curriculum and instruction. Many geographers are involved with Internet-based instruction, which some educators believe has potential to facilitate changes in how we teach and even what we teach. This article describes how the Internet is being used by some geographers for instructional purposes and discusses opportunities for improving teaching and learning with the Internet. 相似文献

后人文主义视角下的中国地缘政治话语研究 总被引：5，自引：2，他引：3
援引后人文主义地理学作为批判地缘政治学的一个延续,以《人民日报》纸媒和官方微博为例,采用NVivo分析和对比分析的方法探讨了“美国反恐”这个当代热点地缘政治话题在两个不同媒体空间被呈现的形式。基于后人文主义思潮对物质的关注,讨论了“人”及其地缘环境认知是否受“物质”(在文中具化为网络技术)影响而动摇其在理解“人地关系”过程中的支配地位。研究发现：一方面网络技术多线参与和呈指数型信息传播的特征使得网络空间出现了多元化的声音并最终呈现出多元和复杂的网络地缘政治景观;另一方面,网络技术迫使当代媒体追求“快”和“新”从而摒弃了传统媒体所强调的权威、真实和逻辑性,取而代之的是情绪化的话语表述,呼应了后人文主义地理学对人以外的要素的关注,讨论了网络技术作为一种物质要素对“人地关系”认知的影响。研究证实,受网络技术及其带来的信息革命的影响,它在一定程度上确实能够对具有主体性的人的地缘认识产生影响。 相似文献

Nightlife settings both facilitate urban sociality and act as sites of social conflict, however little research has focused on experience and encounter in these places. This paper addresses this gap in the context of night‐time economic planning and recent research on encounter. The use of mobile methods in nightlife spaces is shown to garner a more nuanced understanding of how forays into planned night‐time spaces are experienced and understood by people using those spaces. I argue that emplaced, mobile methods unveil complex narratives of place, revealing prejudices and discourses at play in place. These narratives begin to erode privileged images of the city shaped by increasingly neoliberal governance and other cultural intermediaries, and draw out the potential of these methods to improve the lived inclusivity of place. 相似文献

This article introduces an important, but overlooked, actor—the research associate—into methodological discussions about the production of knowledge. We use the term research associate (rather than assistant) to encompass the individuals on whom researchers rely while conducting fieldwork. We seek to avoid the unidirectional hierarchy and power dynamics between researchers and associates, which place the researcher as expert and knowledge producer while obscuring the diversity of roles conducted by field associates. Therefore, throughout this article we examine and destabilize power dynamics and hierarchies and widen the range of what is considered research assistance in the coproduction of knowledge. We also highlight the ways in which geopolitics are written into encounters with ourselves and research associates, encounters that render and reveal the complexities of vulnerability and bodily risk in fieldwork. The goals of this article are threefold: to (1) introduce the influential role of research associates during the production and dissemination of knowledge, (2) situate the work of research associates in both fieldwork and methodological literature, and (3) problematize the invisibility of research associates in academic publications and discuss possible alternatives to how authorship is credited. 相似文献

Both the technology of Internet communication and the size of the Internet itself has advanced exponentially in the last few years. As the technology becomes easier to use, the amount of available scientific data has grown with the Internet. Increasingly, funding agencies require accessible data as a final product for a grant or contract. An impressive amount of such information is available on the Internet now. The conclusion is straightforward, find out what connections are available to you and try them. Subscribing to one of the LISTSERV groups that follow is an easy way to start. If you are interested in further exploring the Internet, I recommend you start by finding a computer with a graphical connection to the WorldWideWeb. From there, the best, and the rest of the Internet is accessible. 相似文献

ABSTRACTAir travel has become central to Australian academic practice, with flying increasingly seen as crucial to the progression of successful academic careers. This paper seeks to understand why academic air travel has come to be perceived as so necessary, particularly given its significant environmental, social, and economic implications. Drawing on the mobilities paradigm and social practice theory, we seek to understand how air travel practices are a key part of contemporary academic careers. We conducted an online survey of 301 academics and 24 in depth semi-structured interviews to understand academic air travel in Australia, finding that it is seen as a means to connect and collaborate within and between academic communities, and to counteract the effects of ‘remoteness'. This remoteness is experienced domestically and internationally, by Australian academics who feel they must travel to perceived centres of knowledge production to further their careers. Academics often frame their ‘need' for connections as necessarily involving physical co-presence. Air travel offers career benefits for those who can take advantage of it, and corresponding drawbacks for those ‘stuck on the ground’. We conclude by discussing the need for valuing localised forms of collaboration as markers of success, and developing imaginative alternatives to academic flying. 相似文献

Abstract This article identifies teaching strategies to explore cultural universals. Traits that contribute to distinguishing one culture from another can be classified into general categories that all cultures share. Students identify universals in their daily lives and then compare and contrast different cultural perspectives through an exploration of these universals. Computer technology provides access to images and information about other cultures that might be used to increase students' understanding of cultural perspectives. The Internet provides a vehicle for classrooms to exchange cooperative creative writing stories that allow students the opportunity to explore different cultural perspectives through the eyes of other students around the world. Suggestions about how to establish and conduct a classroom exchange project over the Internet are provided. 相似文献

This article follows one object, a rare car, through its life cycle and in so doing engages the literatures in cultural geography on mobilities, materiality, and enthusiasm to show how all three are linked in the restoration of this one automobile, a Czechoslovakian-built Tatra T87 from 1941. Through archival and autoethnographic research, we trace the history of the Tatra company and then follow the production, sale, and subsequent ownerships of this one particular car through two wars and across two continents. We detail its restoration, tracing a geography of automobile enthusiasm that brought this rusted hulk back to life, one facilitated internationally by the Internet but that nevertheless demands extraordinary mobilities of cars, people, and parts. In following this one thing, we join other scholars in complicating the commodity- or global-value chains so often described as linear, to uncover instead complex entanglements of reuse, repurposing, and restoration. Because the car in question is our own, we mobilize our experiences with the car to reveal how the geographies of enthusiasms (automotive and otherwise) involve sustained and profound emotional engagements—emotional engagements often left out of academic accounts where, we suggest, they might be desirable as well. 相似文献

超越地理学二元性: 混合地理学的思考 总被引：4，自引：3，他引：1
20世纪的地理学经历了“空间-分析”地理学和“社会-文化”地理学的分裂,对学科的发展带来了持久的影响。本文从历史角度探究“空间-分析”地理学和“社会-文化”地理学分裂的原因,提出保持地理学观点的多样性、促进不同领域的沟通是地理学学科发展的理性选择。在实现“空间-分析”地理学与“社会-文化”地理学沟通的方式方面,地理学认识论与研究方法之间并不存在一一对应的关系,定量方法与定性方法可以在不同领域中混合使用,从而实现对社会-理论与空间-分析隔阂的超越。本文阐释了“混合性”的理念在超越地理学社会-文化/空间-分析二元性中所具备的潜质,并简要总结了混合地理学已有的研究实践,对以“混合性”为基础、面向“后社会-理论、后空间-分析”的地理学未来进行了展望。 相似文献

This Commentary reflects on the state of the scholarship on learning for environmental and natural resource policy and governance. How have we been learning about learning? We highlight theoretical and empirical advancements related to learning, as well as areas of divergence between learning theories and frameworks, and underdeveloped knowledge around processes and outcomes. To address these limitations and improve progress in both theory and practice, we offer recommendations for learning scholarship by focusing on how to collectively engage in ‘learning about learning’. 相似文献

The American Great Plains is a region dominated by a flat, treeless, semiarid environment that has challenged population settlement for over 140 years. As railroad companies successfully attracted pioneers to settle the land, state governments established hundreds of counties. Following Jeffersonian ideals, many of the counties were small in area so they could better serve the local agricultural‐based population. When states established these counties, they envisioned that the population would continue to grow and the Great Plains would become the breadbasket of North America. Unfortunately that did not materialize. A succession of hardships combined with serious environmental constraints has discouraged large‐scale settlement in the region. Many counties reached their maximum population in the early 1900s and their totals have decreased ever since (in some counties by as much as 60 percent to 80 percent). This has led a number of government officials to consider consolidating counties much like school districts have been combined. Using Logan and Gove counties in western Kansas as a case study, our purpose is to understand how attached people are to the county in which they live. Employing multiple methods, we gathered information about how different segments of the population regard their local county. We learned that changing computer technology and the Internet has the biggest impact on peoples' attachment to the county seat. 相似文献

Although viewed by business and commerce as successful solutions, geodemographic profiling of neighbourhoods has attracted wide-ranging criticism in the academic literature. This paper addresses some specific concerns that arise because the derivation of classifications is rarely transparent and open to scrutiny or challenge. The substantive focus of the research reported in this paper is a nationwide geodemographic classification of how people engage with new information and communication technologies (ICTs). In response to the critique of geodemographics as a ‘black box’ technology, we describe how the classification was opened up to public scrutiny and how we conducted a major consultation exercise into the reliability of its results. We assess the message of the 50,000+ searches and 3952 responses collected during the consultation exercise, in terms of possible systematic errors in the shape and detail of the classification. Unusually for Internet-based surveys, we also investigate the likely reliability of the response information received and identify ways in which the outcome of consultation might be used to improve the classification. We believe that this is the first-ever large-scale consultation survey of the validity and remit of a geodemographic classification and that it may have wider implications for the creation of geodemographic classifications. 相似文献

Farmers struggle to afford farmland because competing land uses raise prices higher than what farmers earn, especially in small-scale and sustainable agriculture. Farmers often depend on an intimate partner’s income or labor to access land, yet few studies investigate sexual relationships in farmland access. I interrogate how sexuality shapes land access for small-scale agriculture through participant observation and interviews with 25 queer farmers in New England. I find that queer farmers’ sexual identities and relationships influence where they farm, who they live and work with, how they afford the land, and how they learn to farm. I argue that finding land, labor, credit, and knowledge are intertwined, heteronormative processes of capital accumulation shaped by racism and sexism. Queer farmers’ experiences navigating heteronormativity suggest the relevance of sexuality to land conservation and food justice, limits of organizing land access through sexual relationships, and alternatives to the “family farm.” 相似文献

The wider uptake of GIS tools by many application areas outside GIScience means that many newer users of GIS will have high-level knowledge of the wider task, and low-level knowledge of specific system commands as given in reference manuals. However, these newer users may not have the intermediate knowledge that experts in GI science have gained from working with GI systems over several years. Such intermediate knowledge includes an understanding of the assumptions implied by the use of certain functions, and an appreciation of how to combine functions appropriately to create a workflow that suits both the data and overall goals of the geographical analysis task. Focusing on the common but non-trivial task of interpolating spatial data, this paper considers how to help users gain the necessary knowledge to complete their task and minimise the possibility of methodological error. We observe that both infometric (or cognitive) knowledge and statistical knowledge are usually required to find a solution that jointly and efficiently meets the requirements of a particular user and data set. Using the class of interpolation methods as an example, we outline an approach that combines knowledge from multiple sources and argue the case for designing a prototype ‘intelligent’ module that can sit between a user and a given GIS. The knowledge needed to assist with the task of interpolation is constructed as a network of rules, structured as a binary decision tree, that assist the user in selecting an appropriate method according to task-related knowledge (or ‘purpose’) and the characteristics of the data sets. The decision tree triggers exploratory diagnostics that are run on the data sets when a rule requires to be evaluated. Following evaluation of the rules, the user is advised which interpolation method might be and should not be considered for the data set. Any parameters required to interpolate the particular data set (e.g. a distance decay parameter for Inverse Distance Weighting) are also supplied through subsequent optimisation and model selection routines. The rationale of the decision process may be examined, so the ‘intelligent interpolator’ also acts as a learning tool. 相似文献

Geographies of knowledge, practices of globalization: learning from the oil exploration and production industry 总被引：2，自引：0，他引：2
In this paper we initiate a dialogue between work on the geographies of globalization and knowledge economies, areas of inquiry that have tended to develop in isolation. We argue for a critical harnessing of these two bodies of work to (1) understand how and where different types of knowledge are acquired, produced and mobilized by firms as they seek to 'go global', (2) map the multi-scalar geographies of knowledge that enable practices of globalization and (3) examine the ways in which networks of knowledge structure emerging geographies of production. We demonstrate the potential of this move using oil exploration and production as an example. 相似文献
