Organizations are increasingly turning to enterprise portals to support knowledge work. Portal deployment can be intradepartmental across several business units in one organization or even inter-organizational. Currently in the industry, most of these portals are purchased solutions (e.g., collaboration and smart enterprise suites) and many of these purchasing and selection decisions are primarily driven by the interest of a small group of stakeholders with strong influence from IT vendors. The true requirements for the portal as well as the strategy for its medium- to long-term phased deployment are, in general, poorly addressed. This, together with other reasons, has lead to many failures or to a low adoption rate of the enterprise portal by staff at various levels of an organization. Common problems that hinder portal adoption include lack of an overall governance model, mis-alignment with business processes, poor or non-existent content management (process, tools, and governance), and technical problems associated with the development and configuration of portlets. This article focuses on one critical issue that directly influences the success of an enterprise portal deployment, namely the correct elicitation of user requirements (which in turn lead to the chosen portal’s features and to the style of the portal interface). Taking into consideration the advancement and landscape of commercial portal vendors in the market, this article discusses a bottom-up approach to the identification of high-level drivers for portal usages for its users.

This paper identifies some of the main challenges of data governance modeling in the context of learning analytics for higher education institutions, and discusses the critical factors for designing data governance models for learning analytics. It identifies three fundamental common challenges that cut across any learning analytics data governance model, viz., the ownership of the learning analytics data sets, its interpretation and the enacting of decision-making on the basis of this learning analytics data. It also proposes a set of high-level requirements that are necessary for modeling data governance for learning analytics.

The Impact

The information age has opened powerful new business and social development opportunities throughout the world. The core requirement to realize these opportunities is to provide an environment that allows for the free access of information. Information Technology is changing the way the society functions. Internet is the biggest revolution in human society. The impact of IT can be felt in all economic and social activities in every conceivable manner. The convergence of all forms of communications on the digital play field is opening immense new possibilities of achieving speed, versatility and space-time independence. This paper discusses the paradigm shift in the governance of the citizen. This shift has been possible with the IT revolution and Internet. The e-governance has become citizen-centric. Various issues are being explored to provide the best possible services to citizens. As per the need of the citizens, there is a requirement to identify the issues related to deal with the problems of high level of illiteracy, social diversity and unequal distribution of wealth and low level of woman empowerment so as to conceptualize, design and implement a e-governance model. A brief review of the existing models of e-governance has also been made to crystallize the issues involved.

Governmental Cooperation

The use of Information Communication Technology (ICT) by the public sector is often highlighted as a key tool for the transformation of public sector service delivery. Recent literature reviews have highlighted the limited understanding of the role played by governance, inter-governmental decision making and cooperation when introducing ICT solutions and online services to citizens. As part of a larger qualitative, multi-country comparison, this article compares the Danish and Japanese approaches to electronic governance (eGovernance) and inter-governmental cooperation to answer the question: Does a strong governance model and high level of intergovernmental action lead to the successful supply and use of online citizen services? The analysis finds that the two cases support academic arguments in favour of a strong eGovernance model and a high level of inter-governmental cooperation and decision making.  The article finds that a political- or public sector-driven and motivated public sector modernisation, a consensus seeking and an inter-governmental approach to eGovernment, trust between actors, and the role of formal and informal are important determinants for success, as illustrated by the continued strength of the Danish governance and joint-governmental cooperation model over the more fragmented Japanese approach. Still, both countries would benefit from a more holistic approach to service delivery, process, and organisational reengineering in order to progress further.The analysis finds that the two cases support academic arguments in favour of a strong eGovernance model and a high level of inter-governmental cooperation and decision making.  The article finds that a political- or public sector-driven and motivated public sector modernisation, a consensus seeking and an inter-governmental approach to eGovernment, trust between actors, and the role of formal and informal are important determinants for success, as illustrated by the continued strength of the Danish governance and joint-governmental cooperation model over the more fragmented Japanese approach.

A multisubunit RNA polymerase enzyme is ultimately responsible for transcription initiation and elongation of RNA, but recognition of the proper start site by the enzyme is regulated by general, temporal and gene-specific trans-factors interacting at promoter and enhancer DNA sequences. To understand the molecular mechanisms which precisely regulate the transcription initiation event, it is crucial to elucidate the structure of the transcription factor/DNA complexes involved. Electron spectroscopic imaging (ESI) provides the opportunity to visualize individual DNA molecules. Enhancement of DNA contrast with ESI is accomplished by imaging with electrons that have interacted with inner shell electrons of phosphorus in the DNA backbone. Phosphorus detection at this intermediately high level of resolution (≈lnm) permits selective imaging of the DNA, to determine whether the protein factors compact, bend or wrap the DNA. Simultaneously, mass analysis and phosphorus content can be measured quantitatively, using adjacent DNA or tobacco mosaic virus (TMV) as mass and phosphorus standards. These two parameters provide stoichiometric information relating the ratios of protein:DNA content.

The forte of the Scanning transmission Electron Microscope (STEM) is high resolution imaging with high contrast on thin specimens, as demonstrated by visualization of single heavy atoms. of equal importance for biology is the efficient utilization of all available signals, permitting low dose imaging of unstained single molecules such as DNA.Our work at Brookhaven has concentrated on: 1) design and construction of instruments optimized for a narrow range of biological applications and 2) use of such instruments in a very active user/collaborator program. Therefore our program is highly interactive with a strong emphasis on producing results which are interpretable with a high level of confidence.The major challenge we face at the moment is specimen preparation. The resolution of the STEM is better than 2.5 A, but measurements of resolution vs. dose level off at a resolution of 20 A at a dose of 10 el/A2 on a well-behaved biological specimen such as TMV (tobacco mosaic virus). To track down this problem we are examining all aspects of specimen preparation: purification of biological material, deposition on the thin film substrate, washing, fast freezing and freeze drying. As we attempt to improve our equipment/technique, we use image analysis of TMV internal controls included in all STEM samples as a monitor sensitive enough to detect even a few percent improvement. For delicate specimens, carbon films can be very harsh-leading to disruption of the sample. Therefore we are developing conducting polymer films as alternative substrates, as described elsewhere in these Proceedings. For specimen preparation studies, we have identified (from our user/collaborator program ) a variety of “canary” specimens, each uniquely sensitive to one particular aspect of sample preparation, so we can attempt to separate the variables involved.

Purpose A questionnaire survey was conducted to collect information from clinical audiologists about rehabilitation options for adult patients who report significant auditory difficulties despite having normal or near-normal hearing sensitivity. This work aimed to provide more information about what audiologists are currently doing in the clinic to manage auditory difficulties in this patient population and their views on the efficacy of recommended rehabilitation methods. Method A questionnaire survey containing multiple-choice and open-ended questions was developed and disseminated online. Invitations to participate were delivered via e-mail listservs and through business cards provided at annual audiology conferences. All responses were anonymous at the time of data collection. Results Responses were collected from 209 participants. The majority of participants reported seeing at least one normal-hearing patient per month who reported significant communication difficulties. However, few respondents indicated that their location had specific protocols for the treatment of these patients. Counseling was reported as the most frequent rehabilitation method, but results revealed that audiologists across various work settings are also successfully starting to fit patients with mild-gain hearing aids. Responses indicated that patient compliance with computer-based auditory training methods was regarded as low, with patients generally preferring device-based rehabilitation options. Conclusions Results from this questionnaire survey strongly suggest that audiologists frequently see normal-hearing patients who report auditory difficulties, but that few clinicians are equipped with established protocols for diagnosis and management. While many feel that mild-gain hearing aids provide considerable benefit for these patients, very little research has been conducted to date to support the use of hearing aids or other rehabilitation options for this unique patient population. This study reveals the critical need for additional research to establish evidence-based practice guidelines that will empower clinicians to provide a high level of clinical care and effective rehabilitation strategies to these patients.
