Jornalismo audiovisual: da tela da TV para outras telas

This article is based on research which has been developed in partnership with Unesp TV, a university TV broadcast station of the Universidade Estadual Paulista Julio de Mesquita Filho, Bauru campus/SP. The study aims to identify convergent and divergent aspects in the design of audiovisual journalistic content for TV and other media such as the internet and mobile communication systems. The results presented here are the considerations obtained from the first stage of the research. In this phase, the basic steps which should guide the design of the content to feed broadcasting time are outlined, as well as the online audiovisual news broadcast and business management of a TV station, compared to the model which has been followed by internet TV broadcasters.

TV digital interativa no Brasil: até quando esperar?

The ideal proposed by Decree No. 4901 of 26 November 2003 establishing the Brazilian System of Digital Television (SBTVD) still seems more remote from reality as possible in 2003, where it was believed more in digital inclusion (and social) through access Digital TV via internet than to the development of specifi c products for this media. The reality still shows up differently and it is possible to believe that there was an innocent vision and too optimistic a project that did not meet even the demands of society: SBTVD. The problem to be solved is to get Digital TV adds value to the needs of today’s consumers of content, space has been occupied quickly by computers and devices connected to the internet and even the informal trade of DVDs and video games.

Comunicação pública, transparência e políticas públicas: avaliação de informações em portais brasileiros de governo

An expansion of the professional field of Public Relations can be seen nowadays, influenced by factors such as the increasing use of information and communications technologies for the dissemination of information on public management and the potential creation of dialogue between government and citizens. Despite this trend, there is still a need for specific knowledge about normative aspects of public communication generated by governments on the internet and its role in the fulfillment of the right to information. This article offers a contribution to fulfill the gap of guidelines and standards for professional performance. It describes the results of empirical research which identified the potential contribution of government web portals of the main cities of São Paulo, in the southeastern Brazil, to the strengthening of citizenship, considered in its dimension of exercising the right to information about public policies, particularly those which have an impact on education. The depth and breadth of information were investigated according with twelve categories of evaluation: history; diagnoses; goals; goals; resources and current actions; planned resources and actions; efficiency; effectiveness; impact; cost-effectiveness; user satisfaction; and equity. The data found on the analyzed portals correspond to the average of 11% of which was considered, under the theoretical-methodological context of the research, as information necessary to comprise the full characterization of a public policy in relation to the categories of assessment. Opportunities to improve government web portals were detected, for which we suggest communication management strategies.

A Load-Balancing Shared-Protection-Path Reconfiguration Approach in WDM Wavelength-Routed Networks

Wavelength-routed networks (WRN) are very promising candidates for next-generation Internet and telecommunication backbones. In such a network, optical-layer protection is of paramount importance due to the risk of losing large amounts of data under a failure. To protect the network against this risk, service providers usually provide a pair of risk-independent working and protection paths for each optical connection. However, the investment made for the optical-layer protection increases network cost. To reduce the capital expenditure, service providers need to efficiently utilize their network resources. Among all the existing approaches, shared-path protection has proven to be practical and cost-efficient [1]. In shared-path protection, several protection paths can share a wavelength on a fiber link if their working paths are risk-independent. In real-world networks, provisioning is usually implemented without the knowledge of future network resource utilization status. As the network changes with the addition and deletion of connections, the network utilization will become sub-optimal. Reconfiguration, which is referred to as the method of re-provisioning the existing connections, is an attractive solution to fill in the gap between the current network utilization and its optimal value [2]. In this paper, we propose a new shared-protection-path reconfiguration approach. Unlike some of previous reconfiguration approaches that alter the working paths, our approach only changes protection paths, and hence does not interfere with the ongoing services on the working paths, and is therefore risk-free. Previous studies have verified the benefits arising from the reconfiguration of existing connections [2] [3] [4]. Most of them are aimed at minimizing the total used wavelength-links or ports. However, this objective does not directly relate to cost saving because minimizing the total network resource consumption does not necessarily maximize the capability of accommodating future connections. As a result, service providers may still need to pay for early network upgrades. Alternatively, our proposed shared-protection-path reconfiguration approach is based on a load-balancing objective, which minimizes the network load distribution vector (LDV, see Section 2). This new objective is designed to postpone network upgrades, thus bringing extra cost savings to service providers. In other words, by using the new objective, service providers can establish as many connections as possible before network upgrades, resulting in increased revenue. We develop a heuristic load-balancing (LB) reconfiguration approach based on this new objective and compare its performance with an approach previously introduced in [2] and [4], whose objective is minimizing the total network resource consumption.

MARC 21 e XML como ferramentas para a consolidação da catalogação cooperativa automatizada: Uma revisão de literatura

The cooperation and the sharing of information cataloguing and bibliographical in environment automated, this was only possible with the creation and adoption of interchange format MARC21. But due to the progresses of the technologies of information and communication, of the crescent use of Internet and of the databases and databanks, there were the need of the creation and development of tools that optimize the organization activities, retrieval and interchange of information. XML is one of those developments that have as purpose to facilitate the management, storage and transmission of data through Internet. Before that, it was proposed through a literature revision, to analyze Interchange Format MARC21 and Markup Language XML as tools for the consolidation of the Automated Cooperative Cataloguing, your differences of storage flexibilities, organization, retrieval and interchange of data through Internet. This research made possible the divulgation to the community librarian, through a literature revision, that has been discussed internationally on MARC21 and XML

Customer Evolution in Sales Channel Migration

This research has been triggered by an emergent trend in customer behavior: customers have rapidly expanded their channel experiences and preferences beyond traditional channels (such as stores) and they expect the company with which they do business to have a presence on all these channels. This evidence has produced an increasing interest in multichannel customer behavior and it has motivated several researchers to study the customers’ channel choices dynamics in multichannel environment. We study how the consumer decision process for channel choice and response to marketing communications evolves for a cohort of new customers. We assume a newly acquired customer’s decisions are described by a “trial” model, but the customer’s choice process evolves to a “post-trial” model as the customer learns his or her preferences and becomes familiar with the firm’s marketing efforts. The trial and post-trial decision processes are each described by different multinomial logit choice models, and the evolution from the trial to post-trial model is determined by a customer-level geometric distribution that captures the time it takes for the customer to make the transition. We utilize data for a major retailer who sells in three channels – retail store, the Internet, and via catalog. The model is estimated using Bayesian methods that allow for cross-customer heterogeneity. This allows us to have distinct parameters estimates for a trial and an after trial stages and to estimate the quickness of this transit at the individual level. The results show for example that the customer decision process indeed does evolve over time. Customers differ in the duration of the trial period and marketing has a different impact on channel choice in the trial and post-trial stages. Furthermore, we show that some people switch channel decision processes while others don’t and we found that several factors have an impact on the probability to switch decision process. Insights from this study can help managers tailor their marketing communication strategy as customers gain channel choice experience. Managers may also have insights on the timing of the direct marketing communications. They can predict the duration of the trial phase at individual level detecting the customers with a quick, long or even absent trial phase. They can even predict if the customer will change or not his decision process over time, and they can influence the switching process using specific marketing tools
