大数据背景下国内人文地理研究进展与方法审视

通过梳理人文地理领域杂志近年大数据文章解释其与大数据应用的关系，强调其应用给人文地理学研究带来机遇和挑战：①大数据作为研究方法，不能代替传统人文地理研究范式，而是对现研究方法的补充。大数据和小数据需对话交流；②大数据本身是一种话语权，嵌入人文地理研究系统。保证人文地理学多样性，避免过度依赖大数据，需在批判角度审视和运用；③需关注大数据对于人文地理学研究方法和思想的影响；④运用大数据解读地理和空间过程复杂性的同时，应看到大数据应用对公共服务的潜力，思考其结果如何更好的服务社会。     

In situ Measurements of Oxygen Dynamics in Unsaturated Archaeological Deposits

Oxygen is a key parameter in the degradation of archaeological material, but little is known of its dynamics in situ. In this study, 10 optical oxygen sensors placed in a 2 m deep test pit in the cultural deposits at Bryggen in Bergen have monitored oxygen concentrations every half hour for more than a year. It is shown that there is a significant spatial and temporal variation in the oxygen concentration, which is correlated to measured soil characteristics, precipitation, soil water content and degradation of organic material. In these deposits oxygen typically occurs when the air content of the soil exceeds 10–15% vol, while oxygen dissolved in infiltrating rainwater is of less importance for the supply of oxygen in the unsaturated zone.     

7. TOWARD A GENEALOGY OF THE RESEARCHER AS SUBJECT IN POST/DECOLONIAL PACIFIC HISTORIES

Recent discussion has drawn out some important differences between postcolonial and decolonial theories. The former are associated primarily with the work of South Asian scholars working in cultural, literary, or historical studies; decolonial scholarship, by contrast, is located in Latin America and has emerged from sociological critiques of dependency theory. Shifting the locus of debate to the Pacific centers another subject in globalizing critiques of colonialism: the historian in indigenous communities. In this article, I examine how the role of the researcher is conceptualized in Linda Tuhiwai Smith's landmark work Decolonizing Methodologies: Research and Indigenous Peoples (1999). Revealing tensions between objectivity and intersubjectivity, on the one hand, and between essentialist identity and hybridity, on the other, I ask why Smith's book hinges on dichotomizing nonindigenous and indigenous researchers, who are by turn enabled or constrained in a colonial present. I situate this late twentieth-century subject in a genealogy of indigenous engagement with history and anthropology in New Zealand and contemporary problems of historical justice.     

Experiencing Dracula's homeland

ABSTRACT

Transylvania has not only a geographical location as a province of Romania but also a mental meaning as Dracula's land. Dracula has become an important brand name for Romania, attracting many tourists in recent years – especially after the fall of communism. The main dimensions of Dracula's castle (i.e. Bran Castle) experiences shared online by tourists were identified to ascertain the primary reasons for satisfaction and dissatisfaction with visits and to test whether narratives and satisfaction vary according to the occasion (i.e. Halloween). Quantitative (i.e. computer-based) and qualitative (i.e. narrative) content analyses were conducted on the Web reviews written by visitors. The results reveal that the experiences are multidimensional, and they include the following themes: ‘castle’, ‘visit’, ‘Dracula’, ‘inside’, ‘tourist’, ‘outside’, ‘trip’, ‘souvenirs’, ‘stairs’ and ‘Dracula's castle’. The main reasons for dissatisfaction are overcrowding, which is connected with the outside theme, and the disappointment of tourists regarding the old furniture, which is associated with the inside theme. The results also reveal that visitors are the most satisfied with their experience around the time of Halloween. The narratives shared online emphasise tourists’ need to associate their imaginings with this region and castle, giving their experiences greater meaning through this destination's image as Transylvania.     

What is Geography? Perceptions of first year undergraduates in South Africa

Disciplines such as Geography are well placed to respond to the changing needs of society and the effective application of geographical knowledge to real-world problems. This project surveyed first year Geography undergraduates’ understanding of “What is Geography?”, both before and after an exercise in which geographic topics were identified within recent newspapers. The survey instrument employed was an anonymous, self-administered questionnaire, and was undertaken with first-year undergraduate Geography students at a university in South Africa. Results show that the exercise enabled students (n = 158) to more readily see the application of geographical knowledge to both environmental and social problems that they identified in the newspaper stories. Students also identified that studying Geography may be able to help them increase their skills, employment prospects and earning potential. These findings can help locate the disciplinary concerns and applicability of Geography in post-apartheid South Africa within the wider context of the twenty-first Century world.     

Dewey’s concept of experience for inquiry-based landscape drawing during field studies

The epistemological and educational philosophy of John Dewey is used as a theoretical basis to analyze processes of knowledge construction during geographical field studies. The experience of landscape drawing as a method of inquiry and a starting point for research-based learning is empirically evaluated. The basic drawing skills are acquired through an online drawing course. The main aim is to foster the self-organized acquisition of relevant skills to explore, describe and reflect on subjective mental and linguistic concepts in relation to scientific landscape models. The results, based on an evaluation of the students’ drawings, their responses to questionnaires and a review of students’ “reflective notes”, indicate that the approach motivated students to learn about the processes which formed the landscape and that the students perceived the method of inquiry after Dewey as a way to overcome cognitive dissonance.     

Related variety and the dynamics of European photonic clusters

This article aims at assessing the role of related variety, that is, the relatedness of knowledge bases used by different sectors within a region, as a major driver of clusters’ development. Some recent theoretical papers underline the role of clusters as ‘knowledge platforms’ organizing the recombination of technologies in overlapping industries, following the seminal definition of clusters by Porter as ‘geographic concentrations of linked industries’. In order to investigate the role of related variety in cluster dynamics, we analyse the patterns of development of clusters specializing in photonics in Europe. Photonics constitutes a new and rapidly evolving set of technologies with a high expected degree of technological recombination. However, due to inadequate traditional sectoral classifications, we propose an original method to delineate the perimeter of photonics in patent databases. A two-step algorithm is then used to identify systematically photonic clusters in Western Europe at the local level. In the last part of the paper, a typology of technological trajectories of clusters over the last decades is developed and then correlated with a set of quantitative measures of technological relatedness. The results highly confirm the role of related variety as a major driver of success, particularly for the biggest European clusters.     

Geographies of temporary markets: an anatomy of the Canton Fair

While recent research on temporary clusters and temporary markets has emphasized the knowledge generation processes associated with trade fairs, little is known about the knowledge exchanges that are embedded in market relations at these events. This paper uses the case of the Canton Fair in Guangzhou, the largest trade fair in China, to illustrate that such events do not operate as a single market, but that they generate multiple dynamic market configurations, which entail different flows of knowledge, goods and people. In a typical case study, four types of market configurations are identified that simultaneously develop at this event. The findings contribute to a more comprehensive understanding of the dynamics of market relations, knowledge and transactions in temporary spatial settings.     

Commercializing science: nineteenth- and twentieth-century academic scientists as consultants,patentees, and entrepreneurs

Abstract

The collection of essays introduced in this article contributes to the debate on the commercialization of academic science by shifting the focus from institutional developments meant to foster university technology transfer to the actions of individual scientists. Instead of searching for the origins of the ‘entrepreneurial university,’ this special issue examines the personal involvement of academic physicists, engineers, photographic scientists, and molecular biologists in three types of commercial activity: consulting, patenting, and full-blown business entrepreneurship. The authors investigate how this diverse group of teachers and researchers perceived their institutional and professional environments, their career prospects, the commercial value of their knowledge and reputation, and their ability to exploit these assets. By documenting academic scientists’ response to market opportunities, the articles suggest that, already in the decades around 1900, commercial work was widespread and, in some cases, integral to academics’ teaching and research activity.     

Globalization of the animation industry: multi-scalar linkages of six animation production centers

This paper examines the change in animation production over time and analyzes the different scales of internal and external linkages among six animation production centers. Four types of producers were identified based on their roles in the animation industry and their multi-scalar linkages were investigated for similarities and differences. Several factors including production costs, local skills, government policy and domestic markets were found to affect the growth of new production centers. High value-capture occurs mostly in production centers where tacit knowledge is created. The governance of each animation production center was found to have evolved based on its unique development path within the industry’s global value chain.
