信息化背景下发展型农村地区手机使用人群分化研究——基于晋南村庄的实证调查

随着农村信息化的迅猛发展和手机迅速的普及,手机使用逐渐进入人们的学习、工作和生活之中,改变着人们的思维和行为方式,打破传统人群基于人缘、血缘、地缘、为纽带的人群共同成员感和归属感,进而导致农村地区人群也在走向分化。以晋南村庄的手机使用情况的实地调查数据为依托,采用定性和定量的分析方法,从体制依存和自我依存的两个角度进行分析把握,结果表明,在信息化背景下的手机使用过程使得村庄人群存在明显的分化。结合以上分析,对这种现象进行了初步的了解和掌握,进而探讨这种现象对社会带来的价值与意义。     

Factors Influencing Uptake and Use of a New Health Information App for Young People

Abstract

When young people need health information they are increasingly likely to use online sources and health apps (applications). Yet, these are not necessarily well-designed, reliable or appropriate, and research has primarily focused on adult use. Our study is the first to use qualitative mixed methods (focus groups and interviews) to apply the Technology Acceptance Model (TAM) to understand 26 young people’s uptake and use of a new, clinically-approved health app (application) for 16–25?year olds. We found that perceived usefulness, perceived ease-of-use, social influences and trust, all differently impacted children and young people health-app acceptance and effectiveness. Implications for future research and young-person health-app development are discussed.     

Preparing for ICT enhanced practice learning opportunities in 2010—a speculative view

This paper presents a speculative view of the roles that a practice teacher, student and university may undertake during a practice learning opportunity in the year 2010, based upon predicted advances in information and communication technology (ICT). The article explores the likelihood of such a scenario becoming a reality by examining very briefly current developments in the area of wireless mobile devices and infrastructure. The paper presents an argument drawing on the author’s own experiences that passive acceptance or ignorance through apprehension of ICT developments should not prevent the examination and planning of how this medium may be utilised in the arena of social work in the future. This paper acts as a scenario‐planning device, presenting for discussion some of the issues that may need to be explored if ICT is to become positively integrated into the field of social work education.     

Negotiating the ground: ‘mobilizing’ a divided field site in the ‘post-conflict’ city

ABSTRACT

While an exploration of mobility patterns in ‘post-conflict’ societies has much to tell us about how division is produced through ordinary activities, less work has considered the practical application of a mobilities ‘lens’ during fieldwork in such contexts. Negotiating the ground in highly polarized contexts presents a unique array of challenges, but also offers opportunities to make use of mobile methodologies. This paper discusses the advantages of GPS-based technologies and walking interviews to a recent activity-space segregation study in Belfast, Northern Ireland, and reflects on methodological issues posed by the ‘post-conflict’ field site.     

Mobile phones in Africa: how much do we really know?

Mobile phones are a crucial mode of communication and welfare enhancement in poor countries, especially those lacking an infrastructure of fixed lines. In recent years much has been written about how mobile telephony in Africa is rapidly reducing the digital divide with developed countries. Yet, when one examines the evidence it is not at all clear what is really happening. In one country, Tanzania, for example, some observers point to the fact that 97% of the population lives under the mobile footprint, while others show that ownership is very limited. These extreme values prompted us to review the situation in Africa as a whole, in an effort to discover what is really going on.     

Illuminating urban street (u)topias

ABSTRACT

A utopian vision of the city is often bright, well-lit, and conversely darkness and night are more often associated with dystopia. This paper uses an ethnographic study of night-time in a busy street space in the middle of a south coast UK city in order to demonstrate the application of ‘utopia as method’, or rather utopia as a mobile method in understanding justice and injustice in urban space. In doing so, we suggest the possibilities of urban mobile space, arguing that ‘utopia as method’ originates in Lefebvre’s (1991) work on the possibilities that arise from the seemingly impossible imaginings of urban transformation. We use what are considered to be distinct approaches to photography: ‘ethnographic’ and ‘expressive’ in demonstrating this. Photography tells a story of the lighting of the space in illuminating the street in particular ways and making visible aspects that otherwise may go unnoticed. We draw from the boundaries, of photography (and therefore light), of method, and of urban space, looking to the ‘territorial edges’ for Lefebvre’s possibilities.     

Making ideas “app”-en: the creation and evolution of a digital mobile resource to teach social work interviewing skills

ABSTRACT

This paper describes the processes involved in the design, delivery, and evolution of a mobile app.’ The initial app’ was funded by an institutional Teaching Award to update the delivery of Egan interviewing skills to social work students. The article charts the progress of development, beginning with the initial rationale for the app’ and its subsequent evolution into a Motivational Interviewing resource for social workers within a designated local authority. Arguing for the increasing importance of digital resources, within social work training and practice, the article draws from theories of digital pedagogy, as well as highlighting the work of some prominent figures within this emerging field. The article is written as a collaboration between the lead author and the app’ developers, who have contributed technical detail and emphasized the need for collaboration. Whilst the article touches briefly on the mechanics involved with app creation, its chief aim is to act as a guide to the practical, financial and relational aspects of development – in order that other social work practitioners and educators are inspired to progress their own ideas into innovative digital resources. To facilitate this, the article concludes with a practical list of suggestions for successful digital development.     

Fitting disposition codes to mobile phone surveys: experiences from studies in Finland, Slovenia and the USA

Summary.  Using mobile phones to conduct survey interviews has gathered momentum recently. However, using mobile telephones in surveys poses many new challenges. One important challenge involves properly classifying final case dispositions to understand response rates and non-response error and to implement responsive survey designs. Both purposes demand accurate assessments of the outcomes of individual call attempts. By looking at actual practices across three countries, we suggest how the disposition codes of the American Association for Public Opinion Research, which have been developed for telephone surveys, can be modified to fit mobile phones. Adding an international dimension to these standard definitions will improve survey methods by making systematic comparisons across different contexts possible.
