Transparency laws and interactive public relations: An analysis of Latin American government Web sites

A content analysis of 50 Latin American government Web sites was conducted to assess whether new transparency laws in the hemisphere impacted the interactivity, usability, technological expertise, and national symbolism manifest on the sites. Web sites were found to be generally usable but limited in interactivity. There was no difference in Web site interactivity between countries with transparency laws and those without them, but countries with laws used more visual symbols aimed at national branding. The article offers a model of Web site features for public relations practitioners interested in increasing the sophistication, usability, and interactivity of their sites in order to improve relationship building with stakeholders.     

Scholarly Communication 2.0: Exploring Researchers' Opinions on Web 2.0 for Scientific Knowledge Creation, Evaluation and Dissemination

This paper presents the results of a survey aimed at gauging the potential acceptance of a collaborative and Web 2.0 inspired scholarly communication sector. While this sector has seen the birth of a multitude of innovative initiatives, there is still little empirical evidence of the acceptance of such initiatives by researchers. We received 349 completed questionnaires from researchers of many different disciplines. The results of the survey show that there is a strong positive attitude towards Web 2.0 and open publishing approaches. However, the major challenge still resides in combining free dissemination of results with robust and reliable quality control mechanisms.     

The Role of Innovation Characteristics and Perceived Voluntariness in the Acceptance of Information Technologies

The often paradoxical relationship between investment in information technology and gains in productivity has recently been attributed to a lack of user acceptance of information technology innovations. Diverse streams of research have attempted to explain and predict user acceptance of new information technologies. A common theme underlying these various research streams is the inclusion of the perceived characteristics of an innovation as key independent variables. Furthermore, prior research has utilized different outcomes to represent user acceptance behavior. In this paper we focus on individual's perceptions about the characteristics of the target technology as explanatory and predictive variables for acceptance behavior, and present an empirical study examining the effects of these perceptions on two frequently used outcomes in the context of the innovation represented by the World Wide Web. The two outcomes examined are initial use of an innovation and intentions to continue such use in the future, that is, to routinize technology use. Two research questions motivated and guided the study. First, are the perceptions that predict initial use the same as those that predict future use intentions? Our results confirm, as hypothesized by prior research, that innovation characteristics do explain acceptance behavior. The results further reveal that the specific characteristics that are relevant for each acceptance outcome are different. The second research question asks if perceived voluntariness plays a role in technology acceptance. Results show that external pressure has an impact on adopters' acceptance behavior. Theoretical and practical implications that follow are presented.     

Virtual Communities of Practice in Social Group Work Education

Virtual communities of practice are an international phenomenon in social work around the world. However, they are rare in social work in the United States. This article describes an online community, the Social Group Work Commons, designed to complement courses in social group work. Using Web 2.0 Internet tools, such as blogs, discussion boards, and chats, the developers employed group work skills to help students establish a vehicle for mutual support as students struggled to integrate course content in their field placements. Examples from course blogs indicate students became increasingly intimate in their online exchanges over time and readily provided each other support in applying course content in their practice.     

Model‐based Prediction In Ecological Surveys Including Those with Incomplete Detection

This paper explores and develops model‐based predictors for surveys of plants and wildlife including those with incomplete detection. The methodology allows for estimating a detection function to account for objects which were not detected at the time of the survey. The model‐based theory utilises generalized linear models (GLMs) and is either new or adapted from other areas of sampling. A simulation study is used to validate the estimators and comparisons are made with an integrated likelihood approach. An aerial survey of kangaroos in western New South Wales is used to illustrate the theory. The area within 50m of the aircraft is treated as a strip transect and mark‐recapture methods are used to estimate the detection function.     

Difference-based variance estimator for nonparametric regression in complex surveys

A difference-based variance estimator is proposed for nonparametric regression in complex surveys. By using a combined inference framework, the estimator is shown to be asymptotically normal and to converge to the true variance at a parametric rate. Simulation studies show that the proposed variance estimator works well for complex survey data and also reveals some finite sample properties of the estimator.

第二代互联网的民意价值研究

以用户参与为本质的第二代互联网(Web2.0),以其开放性、真实性、自组织性、聚合性等特性为网络民意表达注入了新元素。相对于第一代互联网,第二代互联网赋予民意表达的价值主要体现在真实与聚合两个方面。真实性强化了网络民意的理性程度,聚合性有效提高信噪比,从而缓解了网络民意过于零散的状态。     

Positive and negative impacts of job loss on family life: the perceptions of Australian car workers

This article contributes to research on the impact of job loss on families. It is based on survey responses from 371 workers and in‐depth interviews with 39 of them about the family impacts of their job loss from the Mitsubishi car factory in Adelaide in 2004–2005. A majority of workers said family life had been affected by their job loss. Quantitative analysis identified four variables significantly associated with family impacts: marital status, children living at home, employment status and financial management. Qualitative responses showed the predominantly negative impacts were financial strain, loss of relationship stability and general stress and worry, although few faced catastrophic impacts from their job loss. However, in contrast to most previous research, the in‐depth interviews also revealed positive impacts from job loss, such as having more time at home and to spend with their family. We conclude that the existence of ongoing income support and public health insurance in Australia were important in avoiding catastrophic financial impacts on these workers and their families.     

Support,social networks and the family in Portugal: two decades of research

This article presents two major surveys, carried out in Portugal, on the inclusion of families and individuals in social networks of support and affinity. The first, dating from 1999, sought comprehensively to reconstruct families' social networks by mapping effective support relations. The second survey, fielded in 2009–10, followed a family configuration perspective which sought to reconstruct individuals' networks of close relationships, and the issue of informal support only arose as providing further insight into the characteristics of personal networks. Both surveys will be analysed from a comparative perspective which, while stressing their different but connected conceptual orientations, compares each one's methodological strategies and operationalization procedures. Finally, the main results of each survey are outlined, leading to a brief discussion of the ways in which the two surveys complement each other.
