Facet-based opinion retrieval from blogs

The paper presents methods of retrieving blog posts containing opinions about an entity expressed in the query. The methods use a lexicon of subjective words and phrases compiled from manually and automatically developed resources. One of the methods uses the Kullback–Leibler divergence to weight subjective words occurring near query terms in documents, another uses proximity between the occurrences of query terms and subjective words in documents, and the third combines both factors. Methods of structuring queries into facets, facet expansion using Wikipedia, and a facet-based retrieval are also investigated in this work. The methods were evaluated using the TREC 2007 and 2008 Blog track topics, and proved to be highly effective.     

Information Privacy in the Marketspace: Implications for the Commercial Uses of Anonymity on the Web

While there is no question that the commercial development of the World Wide Web is still in its infancy and growing rapidly, this development faces a serious barrier to ultimate commercialization. In this article we develop the argument that the primary barrier to the successful commercial development of the Web is the current lack of consumer trust in this new commercial medium. This lack of trust is engendered primarily by the industry's documented failure to respond satisfactorily to mounting consumer concerns over information privacy in electronic, networked environments. We examine how such concerns are affecting the growth and development of consumer-oriented commercial activity on the World Wide Web and investigate the implications of these concerns for potential industry response. In the short run, the commercial development of the Web depends on giving consumers the opportunity to be anonymous when engaging in information exchanges and online transactions. Ultimately, however, commercial Web providers must come to realize that the Internet dramatically shifts the balance of power between a business and its customers, and therefore, radical new business strategies will be required for long-term success. Because the Web offers unprecedented opportunities for interacting with customers, strategies that take advantage of the medium's unique features are likely to reap important rewards in customer satisfaction, loyalty, and retention. Therefore, in the long run, the most effective way for commercial Web providers to develop profitable exchange relationships with online customers is to gain consumer trust by allowing the balance of power to shift toward more cooperative interactions between firms and their customers.     

Curriculum and Society: Rethinking the Link

This article argues that the link between educational curricula and society as a whole has become critically uncertain. This crisis is linked to a number of factors related to the post-modern world view, including: the disappearance of grand utopian social visions of the kind that used to underpin educational policy; the lack of adequate theoretical tools; and the way in which academics are exposed to a multitude of different cultural norms. The author argues that this situation calls for a fundamental re-thinking of the link between curriculum and society, based on a more flexible and pluralistic approach.     

School Enrolment Patterns in Rural Ghana: A comparative study of the impact of location,gender, age and health on children's access to basic schooling

The aim of this article is to discuss the results from three censuses conducted on school age children in rural Ghana which reveal contemporary patterns in enrolment. The data provide a profile of the school age population in basic education and contribute novel quantitative data on children out of school. The article examines the age at first enrolment, the gender disparities between classes, the classes where children drop out, and the proportion of children who never enrol in school. The stark contrast in enrolment between the disadvantaged north and the south of the country is also confirmed. Qualitative data from focus group discussions with parents, teachers and children highlight the major obstacles confronting education-these include a diversity of factors such as child labour, health, location and gender. Suggestions of policy options needed to increase access and attainment to schooling include reducing the over-age entry, increasing female access and participation, adapting culturally sensitive strategies, collecting better statistical data, improving the health of school age children and lessening the gap between the north and south of the country.     

ATHENS,gateways, and portals: components of the Distributed National Electronic Resource

The Distributed National Electronic Resource is a central plank of the UK's Joint Information Systems Committee's strategy. We outline the background and definitions of the DNER and discuss some of the issues to be investigated and the collaboration required between stakeholders and their partners.     

The Act of Looking: Wofgang Iser's Literary Theory and Meaning Making in the Visual Arts

In his account about reading novels, Wolfgang Iser argued that the work of art is not the text itself but the experience that emerges as a reader interacts with the text. Yet, he clarified that the aesthetic object is not based only on the subjective input of the reader but also determined by specific signs that a text presents. This article draws from Iser's theories to examine the process through which five teenagers discover meaning in an abstract sculpture by artist Isamu Noguchi. The author shows how the young viewers arrived at a series of readings that were elicited by the qualities of the work and that built upon each other in a sort of snowballing process. The article also illustrates how the sort of meaning that an artwork can yield stretches throughout the whole experience and can therefore not be translated into a discursive statement.     

Product portfolio performance in new foreign markets: The EU trademark dual system

How do intellectual propriety rights (IPRs) help firms profit from their innovation? Innovation literature frequently turns to patents to measure innovative IPR, but more recent work shifts focus to the other side of IPR, namely, trademarks. This article therefore discusses the effects of trademark strategies when companies decide to introduce their product portfolios in a new foreign market. Entrants might opt for a common trademark across different country markets (integration) or use several country-specific trademarks (responsiveness). This empirical study exploits the quasi-natural experiment created by the tariff shock that affected Spain when it joined the European Union in the 1990s. Data from the automotive industry reveal how non-European companies that already operated in other European countries sought to enter Spain rapidly, using various trademark strategies. The product portfolio characteristics are fixed at entry, so this study can specify how and when trademark responsiveness versus integration affects firm performance. The results reveal that trademark responsiveness increases firm performance if the firms suffer high liabilities of foreignness or newness.     

National identity in the historical narratives of a morally questionable historical process / Identidad nacional en las narrativas sobre un proceso histórico moralmente cuestionable

Different studies have shown that national groups construct a positive social identity through the appropriation of heroic narratives about the national past. Within this framework, this research studied the narratives of Argentine university students (n = 27), without specific training in history about a historical process in which their national state carried out morally questionable actions. Specifically, we analysed their narratives on the ‘Conquest of the Desert’, a military campaign carried out in the late nineteenth century which entailed the genocide of the indigenous peoples who inhabited most of what is today Argentina. Through semi-structured interviews, it was revealed that although the grammar of the participants’ narratives is generally poor, it is possible to identify in them two clashing groups as agents of that historical process. Furthermore, the participants did not use the pronouns we/us to refer to any of these groups, so they did not identify with them. We conclude that the poverty of the participants’ narratives may reveal a collective attempt to forget this morally condemnable historical process, which would also have been expressed in the shift of responsibility from the Argentine state to other social groups in most of the narratives analysed. Likewise, failure to identify with the victims, even in cases in which it was considered to be the national state, shows the implementation of cognitive strategies to preserve a positive identity.     

Academic inbreeding and publication activities of Russian faculty

The literature on the consequences of academic inbreeding shows ambiguous results: some papers show that inbreeding positively influences research productivity measured by the quantity and quality of publications, while others demonstrate the opposite effect. There are contradictory results both in the studies of different countries and within countries. This variety of results makes it impossible to transfer the findings from one academic system to another, and in Russia this problem has been under-explored. This paper focuses on the relationship between inbreeding and publication activity among Russian faculty. The research was conducted using data from the ‘Monitoring of Educational Markets and Organizations’ survey. The results show that there is no significant effect of academic inbreeding on publication productivity: no substantial and robust differences in publication activity between inbreds and non-inbreds have been found. The paper finishes with a discussion of possible explanations inherent in the Russian academic system.
