旅游与人类学:研究与实践

旅游快速发展的50年内,旅游和人类学学科的关系错综复杂,它们之间更多的是矛盾而不是和谐共处的关系.人类学的理论体系一直被用来批评旅游以及阐述旅游给当地社会文化所造成的不利影响.大众旅游对少数民族文化的影响尤其受到指责.但是近年来,情况有所变化,人类学的理论开始用于指导旅游的发展、减少旅游对社区的不利影响.     

Reciprocal Relationships between Trajectories of Depressive Symptoms and Screen Media Use during Adolescence

Adolescents are constantly connected with each other and the digital landscape through a myriad of screen media devices. Unprecedented access to the wider world and hence a variety of activities, particularly since the introduction of mobile technology, has given rise to questions regarding the impact of this changing media environment on the mental health of young people. Depressive symptoms are one of the most common disabling health issues in adolescence and although research has examined associations between screen use and symptoms of depression, longitudinal investigations are rare and fewer still consider trajectories of change in symptoms. Given the plethora of devices and normalisation of their use, understanding potential longitudinal associations with mental health is crucial. A sample of 1,749 (47% female) adolescents (10–17 years) participated in six waves of data collection over two years. Symptoms of depression, time spent on screens, and on separate screen activities (social networking, gaming, web browsing, TV/passive) were self-reported. Latent growth curve modelling revealed three trajectories of depressive symptoms (low-stable, high-decreasing, and low-increasing) and there were important differences across these groups on screen use. Some small, positive associations were evident between depressive symptoms and later screen use, and between screen use and later depressive symptoms. However, a Random Intercept Cross Lagged Panel Model revealed no consistent support for a longitudinal association. The study highlights the importance of considering differential trajectories of depressive symptoms and specific forms of screen activity to understand these relationships.     

Beyond the state? Civil sociality and other notions of citizenship

Social scientists generally begin with a definition of citizenship, usually the rights-bearing membership of nation-states, and have given less attention to the notions of citizenship held by the people whom they study. Not only is how people see themselves as citizens crucial to how they relate to states as well as to each other, but informants' own notions of citizenship can be the source of fresh theoretical insights about citizenship. In this article I set out the four notions of citizenship that I encountered during interviews and participant observation across two contrasting regions of Mexico in 2007–2010. The first three notions of citizenship were akin to the political, social and civil rights of which social scientists have written. I will show that they took particular forms in the Mexican context, but they did still entail a relationship with nation-states – that of claiming rights as citizens on states. But the most common notion of citizenship, which has been little treated by social scientists, was of civil sociality – to be a citizen was to live in society, ideally in a civil way. I argue that civil sociality constitutes a kind of citizenship beyond the state, one that is not reducible to the terms in which people relate to states.     

3D documentation of footwear impressions and tyre tracks in snow with high resolution optical surface scanning

The three-dimensional documentation of footwear and tyre impressions in snow offers an opportunity to capture additional fine detail for the identification as present photographs. For this approach, up to now, different casting methods have been used. Casting of footwear impressions in snow has always been a difficult assignment. This work demonstrates that for the three-dimensional documentation of impressions in snow the non-destructive method of 3D optical surface scanning is suitable. The new method delivers more detailed results of higher accuracy than the conventional casting techniques. The results of this easy to use and mobile 3D optical surface scanner were very satisfactory in different meteorological and snow conditions. The method is also suitable for impressions in soil, sand or other materials. In addition to the side by side comparison, the automatic comparison of the 3D models and the computation of deviations and accuracy of the data simplify the examination and delivers objective and secure results. The results can be visualized efficiently. Data exchange between investigating authorities at a national or an international level can be achieved easily with electronic data carriers.     

Application of 3D documentation and geometric reconstruction methods in traffic accident analysis: with high resolution surface scanning, radiological MSCT/MRI scanning and real data based animation

The examination of traffic accidents is daily routine in forensic medicine. An important question in the analysis of the victims of traffic accidents, for example in collisions between motor vehicles and pedestrians or cyclists, is the situation of the impact. Apart from forensic medical examinations (external examination and autopsy), three-dimensional technologies and methods are gaining importance in forensic investigations. Besides the post-mortem multi-slice computed tomography (MSCT) and magnetic resonance imaging (MRI) for the documentation and analysis of internal findings, highly precise 3D surface scanning is employed for the documentation of the external body findings and of injury-inflicting instruments. The correlation of injuries of the body to the injury-inflicting object and the accident mechanism are of great importance. The applied methods include documentation of the external and internal body and the involved vehicles and inflicting tools as well as the analysis of the acquired data. The body surface and the accident vehicles with their damages were digitized by 3D surface scanning. For the internal findings of the body, post-mortem MSCT and MRI were used. The analysis included the processing of the obtained data to 3D models, determination of the driving direction of the vehicle, correlation of injuries to the vehicle damages, geometric determination of the impact situation and evaluation of further findings of the accident. In the following article, the benefits of the 3D documentation and computer-assisted, drawn-to-scale 3D comparisons of the relevant injuries with the damages to the vehicle in the analysis of the course of accidents, especially with regard to the impact situation, are shown on two examined cases.     

Managing organizations in the third world: A case study of management control in a Bangladeshi jute mill

This article reports on a study of the operation of management control systems in a large nationalized jute mill of Bangladesh. The study seeks to describe how ‘control’ operated in practice and to explain why the systems of control worked in these ways. Investigations revealed a number of significant factors. First, the organization operated in both competitive and regulated environments; it had little authority over its operational activities and, head office and the sponsoring ministry were prominent in organizational planning and control. Second, the accounting system in the mill was mainly a response to external legitimacy (e.g. stewardship and tax matters). Third, although budgeting was perceived as part of the formal structure of control, it was not a dominant mode of control in the organization; the budgeting system was created to comply with head office and state requirements. Fourthly, the mill managers used a variety of social/informal control and mechanisms to cope with the complexity and uncertainty around the mill's operations. This study reinforces the conclusions of other research claiming that the wider social, economic, political and institutional contexts govern the ways management control operates in an organization.     

Corporate citizenship: Creating social capacity in developing countries

A corporation has only limited ability to create social capital through philanthropic activity, and, in the context of a decline in official aid, the corporate sector is increasingly assuming a de facto developmental role. The presence of social capital assists communities in moving towards sustainable development and may contribute to the business case for corporate–community partnerships. While it is not the role of corporations to deliver social services, their ability to enhance social capital by partnering with community organisations can contribute both to development and work to their own commercial advantage. Such partnerships, whether philanthropic or commercial, will be more effective if delivered through balanced and transparent relationships with community organisations that help to create social capacity at the local level.     

Elite networks and worldviews during the Yel'tsin years

Conflict characterised Russian elite politics during the Yel'tsin years. This article adopts a network approach to understand the sources of elite contention in one Russian locality between 1994 and 2000. The findings suggest that elite conflict during the Yel'tsin years had its roots in structural and cultural forces deeper than control over official positions and differences in socio-demographic characteristics. The article reveals that elites fragmented over time into factions. Rather than having a unifying culture, elites from different factions held distinct worldviews that were patterned by their networks. The characteristics of their worldviews matched the structural properties of elite factions and reinforced differences between them.
