Support infrastructures for multimedia services with guaranteed continuity and QoS

Advances in wireless networking and content delivery systems are enabling new challenging provisioning scenarios where a growing number of users access multimedia services, e.g., audio/video streaming, while moving among different points of attachment to the Internet, possibly with different connectivity technologies, e.g., Wi-Fi, Bluetooth, and cellular 3G. That calls for novel middlewares capable of dynamically personalizing service provisioning to the characteristics of client environments, in particular to discontinuities in wireless resource availability due to handoffs. This dissertation proposes a novel middleware solution, called MUM, that performs effective and context-aware handoff management to transparently avoid service interruptions during both horizontal and vertical handoffs. To achieve the goal, MUM exploits the full visibility of wireless connections available in client localities and their handoff implementations (handoff awareness), of service quality requirements and handoff-related quality degradations (QoS awareness), and of network topology and resources available in current/future localities (location awareness). The design and implementation of the all main MUM components along with extensive on the field trials of the realized middleware architecture confirmed the validity of the proposed full context-aware handoff management approach. In particular, the reported experimental results demonstrate that MUM can effectively maintain service continuity for a wide range of different multimedia services by exploiting handoff prediction mechanisms, adaptive buffering and pre-fetching techniques, and proactive re-addressing/re-binding.

A multimedia system to produce and deliver video fragments on demand on parliamentary websites

[EN]Parliamentary websites have become one of the most important windows for citizens and media to follow the activities of their legislatures and to hold parliaments to account. Therefore, most parliamentary institutions aim to provide new multimedia solutions capable of displaying video fragments on demand on plenary activities. This paper presents a multimedia system for parliamentary institutions to produce video fragments on demand through a website with linked information and public feedback that helps to explain the content shown in these fragments. A prototype implementation has been developed for the Canary Islands Parliament (Spain) and shows how traditional parliamentary streaming systems can be enhanced by the use of semantics and computer vision for video analytics...

European and Chinese legislation regulating the portrayal of women in television advertising: A comparison

This dissertation has two main purposes. On the one hand, it aims at comparing the gender stereotypes presented in the television commercials in China and in Europe. Considering the cultural, historical and socio-economical differences between these two contexts, it is interesting to examine the gender role models offered and used by the advertising industry in European Union and China in order to see if the gender stereotypes are similar and to evaluate to which extent they reflect, challenge or reinforce the gender roles of the society where they are broadcasted. On the other hand, the objective of this dissertation is to establish the degree of adequateness and effectiveness of the existing regulatory framework through an analysis of the positive and negative aspects of the regulatory acts issued to safeguard a fair representation of genders in the EU Member States and in China.

Educational Television Broadcasting in Germany: Prevailing Practices, Existing Challenges and Adoptable Policies

Television is widely used for educational purposes but has still not achieved its fullest potential neither in developed nor in developing countries. This worldwide under performance invite experts and academics to join hands to search causes and provide suggestions to make television a better and popular learning tool. Guided by this philosophy, the present paper analyzes the educational television broadcasting in Germany from different perspectives. The focus of analysis includes measures and practices adopted by German institutions/broadcasters to promote educational television. Besides dealing with these issues, the paper discusses existing challenges and suggests best adoptable educational television broadcasting polices from Germany to promote educational television in global perspectives.

“Advertising Psychology – The Blog Seminar”.

The aim of the web-based course “Advertising Psychology – The Blog Seminar” was to offer a contemporary teaching design using typical Web 2.0 characteristics such as comments, discussions and social media integration which covers facebook and Twitter support, as nowadays, this is a common part of students’ everyday life. This weblog (blog)-based seminar for Advertising Psychology was set up in order to make the course accessible to students from different campuses in the Ruhr metropolitan area. The technical aspect of the open-source content management system Drupal 6.0 and the didactical course structure, based on Merrill’s five first principles of instruction, are introduced. To date, this blog seminar has been conducted three times with a total of 84 participants, who were asked to rate the course according to the benefits of different didactical elements and with regard to Kirkpatrick’s levels of evaluation model. This model covers a) reactions such as reported enjoyment, perceived usefulness and perceived difficulty, and b) effects on learning through the subjectively reported increase in knowledge and attitude towards the seminar. Overall, the blog seminar was evaluated very positively and can be considered as providing support for achieving the learning objectives. However, a successful blended learning approach should always be tailored to the learning contents and the environment.

A study of the impact of cigarette advertising on adolescent susceptibility to smoking among 5th-, 8th-, and 12th-grade students in Hempstead and Hitchcock Independent School Districts

This study assessed the impact of cigarette advertising on adolescent susceptibility to smoking in the Hempstead and Hitchcock Independent School Districts. A convenience sample of 217 youths, 10-19 years of age was recruited in the study. Students completed both a paper-and-pencil and a computer-aided questionnaire in April 1996. Adolescents were defined as susceptible to smoking if they could not definitely rule out the possibility of future smoking. For the analysis, an index was devised: a 5-point index of an individual's receptivity to cigarette advertising. The index is determined by the number of positive responses to five survey items (recognizing cigarette brand logos, recognizing cigarette advertisement's pictures, recognizing cigarette brand slogans, evaluating adolescent attitudes toward cigarette advertising, and the degree to which adolescents were exposed to cigarette advertisements). Using logistic regression, we assessed the independent importance of the index in predicting susceptibility to smoking and ever smoking after adjusting for sociodemographic variables, perceived school performance and family composition. Of students surveyed, 54.4% of students appeared to have started the smoking uptake process as measured by susceptibility to smoking. Camel was recognized by the majority of students (88%), followed by Marlboro (41.5%) and Newport (40.1%). The pattern for recognition of the cigarette advertisements was the same as the pattern of market for cigarette. Advertisement featuring the cartoon character Joe Camel was significantly more appealing to adolescents than were advertisements with human models, with animal models, and with text only (p $<$ 0.001). Text only advertisement was significantly less appealing than other types of advertisements. The cigarette advertisement with White models (Marlboro) had significantly higher appeal to White students than to African-American students (p $<$ 0.001). The cigarette advertisement featuring African-American models (Virginia Slims) was significantly more appealing to African-American students than other ethnic groups (p $<$ 0.001). Receptivity to cigarette advertising was to be an important concurrent predictor of past smoking experience and intention to smoke in the future. Adolescents who scored in the fourth quartile of the Index of Receptivity to Cigarette Advertising were 7.54 (95% confidence interval (CI) = 1.92-29.56) times as likely to be susceptible to smoking, and were 4.56 (95% CI = 1.55-13.38) times as likely to have tried smoking, as those who scored in the first quartile of the Index. The findings confirmed the hypothesis that cigarette advertising may be a strong current influence in encouraging adolescents to initiate the smoking uptake process than sociodemographic variables, perceived school performance and family composition. ^

Rezension zu: Irini Katsirea, Public Broadcasting and European Law

Public broadcasting has always been a regulatory field somewhat zealously guarded within the nation states' sphere and kept willingly untouched by regional or international rules. Values inherent to the role of public broadcasting, such as cultural and national identity, social cohesion, pluralism and a sustained public sphere, were thought too critical and too historically connected with the particular society to allow any "outside" influence. Different regulatory models have emerged to reflect these specificities within the national boundaries of European countries. Yet, as media evolved technologically and economically, the constraints of state borders were rendered obsolete and the inner tension between culture and commerce of the television medium became more pronounced. This tension was only intensified with the formulation of a European Community (EC) layer of regulation, which had as its primary objective the creation of a single market for audiovisual services (or as the EC Directive beautifully put it, a "Television without Frontiers"), while also including some provisions catering for cultural concerns, such as the infamous quota system for European and independent productions. Against this backdrop, public broadcasting makes a particularly intriguing subject for a study of regulatory dilemmas of national versus supranational, integration versus intergovernmentalism, culture versus commerce, intervention versus liberalisation, and all this in the dynamic setting of contemporary media. The present paper reviews Irini Katsirea's book PUBLIC BROADCASTING AND EUROPEAN LAW and seeks to identify whether all elements of the complex governance puzzle of European public service broadcasting rules are analytically well fitted together.
