Mobile content contribution and retrieval: An exploratory study using the uses and gratifications paradigm     

Alton Y.K. Chua^{Author Vitae} 《Information processing & management》2012,48(1):13-22

Using the uses and gratifications (UnG) theory, this paper explores the gratification factors for which people contribute and retrieve mobile content. Through the deployment of MobiTOP, a mobile content sharing application, it was found that perceived gratification factors for mobile content contribution were different from those for mobile content retrieval. In particular, factors which had significant positive effects on content contribution stemmed from leisure/entertainment and easy access. Factors fuelling content retrieval included the efficient provision of information resources/services and the need for high quality information, both of which tend to be information-centric. Interestingly, gratification factors for mobile content contribution were also found to have significant effects on mobile content retrieval intention and vice versa. Specifically, the access gratification factor had a significant positive effect on content retrieval intention while the self-gratification factor for content contribution had a significant negative effect on content retrieval intention.  相似文献   

Locking the virtual filing cabinet: A researcher's guide to Internet data security     

Jonathan E. Westfall  Cindy M. KimAuthor VitaeAnnie Y. MaAuthor Vitae 《International Journal of Information Management》2012

As the Internet has grown in popularity, the opportunity it provides for conducting research has also become too large for researchers to ignore. Thus many have flocked to put surveys, experiments, and other data collection measures online in an attempt to gather empirical evidence in a variety of fields. While some choose a commercial provider to host surveys or experiments, others require the additional flexibility that comes with creating and maintaining a custom server. Herein lies a crucial problem: Most researchers lack the skills necessary to design, implement, and manage a server end-to-end. To overcome this limitation, they often hire programmers and administrators, who while usually competent, are not ultimately accountable to granting agencies funding research or Institutional Review Boards overseeing the research. This puts the researcher in a position of accountability in data security, confidentiality, and privacy concerns. The goal of the present paper is to outline a typical server setup, and highlight issues pertaining to data security in language accessible to researcher. This paper also presents data collected and analyzed from an anonymous distributed survey asking researchers questions assessing their management of research data. Our findings from the responses confirmed the legitimacy of our concerns by demonstrating the evident need for stricter security measures in research settings. By reading this paper, we hope that researchers will be cognizant of the optimal security practices which can be equipped to avoid the extreme consequences of data security breaches and gain a deeper understanding of the software they use to collect research data.  相似文献   

DNA-like linguistic secret sharing for strategic information systems     

Marek R. Ogiela  Urszula OgielaAuthor Vitae 《International Journal of Information Management》2012

The development of DNA cryptography has contributed to the ability of solving many computationally difficult problems by offering the capability of executing calculations in parallel. This capability is used particularly in solving NP-complete problems or implementing cryptography and steganography solutions. Biological computation models based on bonds between nitrogen bases in nucleic acid chains that make up DNA structures can also be used to develop new solutions for smart information management. This study discusses new secret splitting techniques based on mathematical linguistic methods and designed for intelligently managing secret data within hierarchical structures. These techniques make use of information coding models found in the coding of DNA sequences.  相似文献   

Critical issues pertaining to the planning and implementation of E-Government initiatives     

Wade R. RoseAuthor Vitae  Gerald G. Grant 《Government Information Quarterly》2010

E-Government initiatives of varying scope and complexity have been implemented at the municipal and other levels of government throughout the world. These projects have been chronicled in both academic and practitioner journals and the proceedings of various E-Government conferences. As a consequence of this growing body of data, it is now possible to look across the experiences of numerous governments to understand if there are common issues that may impact the probability of success of E-Government programs. This paper examines the literature to search for critical planning and implementation issues that have had significant effects upon the success of E-Government initiatives. A conceptual framework is proposed which contributes to the theoretical understanding of E-Government initiative planning and implementation, and may inform practitioner success with new E-Government initiatives.  相似文献   

Information governance,records management,and freedom of information: A study of local government authorities in England     

Elizabeth Shepherd  Alice StevensonAuthor VitaeAndrew FlinnAuthor Vitae 《Government Information Quarterly》2010

In many democratic states political rhetoric gives weight to increasing public participation in and understanding of the political process; (re)-establishing public trust in government decision making; increasing transparency, openness, and accountability of public authorities; and, ultimately, improving government decision-making on behalf of citizens. Access to the public record and freedom of information (FOI) are mechanisms which help to facilitate the accountability of public authorities. Many jurisdictions have introduced legislation related to these mechanisms, and the UK government is no exception with its enactment of the Freedom of Information Act (FOIA) in 2000. University College London (UCL) ran a research project over 12 months in 2008–2009, funded by the UK Arts and Humanities Research Council. The research project examined what the impact of the UK FOIA had been on records management services in public authorities, especially local government. This article reports on some of the findings of the study. It considers how FOI compliance and records management functions are organized in local government and the role of information governance which is emerging as an umbrella for such functions. It draws some conclusions about the contributions that records management services make to the ability of local authorities to comply with the FOIA and identifies some ways in which user experience may be affected by the management of records.  相似文献   

Resistance and support to electronic government,building a model of innovation     

W.E. Ebbers  J.A.G.M. van DijkAuthor Vitae 《Government Information Quarterly》2007

In several countries forces that resist e-government innovations apparently override those that support them. A first step is taken in order to identify organizational processes of resistance and support to e-government innovations. A multi-disciplinary and non-linear innovation model is proposed that is inspired by the Minnesota Innovation Research Program's Innovation Pathway-model. The proposed model grasps the whole process of adoption and implementation of e-government services. Observable indicators of resistance and support on the complete innovation pathway of electronic government are derived from the proposed model. Future research will have to conceptually refine and empirically test both model and indicators.  相似文献   

Finding the skills for tomorrow: Information literacy and museum information professionals     

Paul F. Marty Author vitae 《Museum Management and Curatorship》2006,21(4):317-335

This paper presents results from 21 semi-structured interviews with museum information professionals who were asked about their experiences working with information resources, tools, and technologies in museums. The interviews were analyzed to develop an understanding of the information literacy skills of museum information professionals. This paper presents the results of this analysis, and discusses the state of information literacy in museums, and the increasing need for museum information professionals to possess information literacy skills. The results illustrate how information literacy is defined by information professionals in museums, and how perceptions of information literacy and its importance to museums have changed over time.  相似文献   

Public memories and private tastes: The shifting definitions of museums and their visitors in the UK     

Gayle McPherson ^{Author Vitae} 《Museum Management and Curatorship》2006,21(1):44-57

There is no doubt that museums now operate in a distinctly different market to those of the past. Rottenberg [Rottenberg, B. (2002). Museums, information and the public sphere. Museum International, 54(4), 21-28] identifies the two major trends in museums in the latter years of the 20th century as being ‘the prevalence of a new market-orientated ideology that stressed the importance of revenue generation’ and ‘the introduction of new technologies that transfixed not only the museum profession, but also the world’. The main impact, which these and other changes have had is the revision of the museum into a setting for recreational experiences [Foley, M. and McPherson, G. (2000). Museums as leisure. International Journal of Heritage Studies 16(2), 161-174; Stephen, A. (2001). The contemporary museum and leisure: Recreation as a museum function. MuseumManagement and Curatorship 19(3), 297-308], rather than an educative one. This paper attempts to address some of these shifts in ideology and purpose.The main concern that museums face as they become more ‘recreation-focused’ is that they will lose what has long been believed to be their ‘integrity’, and thus stray from their original missions to preserve and educate, with critics suggesting that they may simply become arenas for pleasure rather than education.This paper concludes that in future, it seems inevitable that museums will become ‘hybrid places, combining recreation and learning, allowing visitors diversions from the intense stimuli of strolling through galleries and viewing multitudinous objects’ [Kotler, N. (2004). New ways of experiencing culture: the role of museums and marketing implications. Museum Management and Curatorship, 19(4), 417-425], with entertainment and education working together to fulfil the museum's mission. Museums need not be afraid of using entertainment, but should embrace it as a tool for learning, potentially attracting a wider and more diversified public.  相似文献   

The role of cognitive competence in the art museum experience   总被引：1，自引：0，他引：1  

Ladislav Kesner ^{Author Vitae} 《Museum Management and Curatorship》2006,21(1):4-19

The gap between the potential for works of art in museums to offer unique experiences, and the actual outcomes of visitor encounters, highlights the importance of the cultural competence of museum visitors. However, when applied to museum visiting, cultural competence should be primarily treated as perceptual and cognitive—one needs to exercise the perceptual activities that works of art require in order for a museum visit to register as some form of satisfying experience. The main part of the paper is devoted to discussion of some aspects of the perceptual basis of cultural competence required for perception of works of art—the problem of attention, the misplaced dichotomy of ‘museum viewing’ versus ‘everyday perception’, and the problem of defining the current cognitive style. It is argued that one of the greatest challenges to the museological profession is the problem of how to engage the complex issues of perception, vision and subjective experience more properly in the museological discourse, so that they can be reflected in theories of presentation and interpretation.  相似文献   

课程目标:理解的视角——以有理数乘法运算为例     

巩子坤 《教育研究》2011,(7)

学生的理解水平、认知发展水平是制定课程目标的重要依据。只有厘清、界定了学生的实际理解水平,才能寻求、探查到一个多数人都能达到的目标层次,制定出适切的课程目标。以有理数乘法运算为例,学生对有理数乘法运算的理解具有层次性与有限性。由低到高,理解的三个水平为程序理解、直观理解、抽象理解。学生对有理数乘法运算的理解是非常有限的,原因在于知识的超验性与学生认知发展的层次性。对照义务教育课程标准发现,课程目标要求偏高,课程目标表述模糊。因而,课程目标需要基于学生的理解水平,具有层次性、明确性、适切性。  相似文献
