SUMMARY

The visual representation of meaning is an extremely complex activity in computer system design. Apart from a few simple guidelines for screen design, little attention is being paid to the visual construction of meaning by means of illustrations, diagrams, symbols, etc. Also no widely agreed set of icons or symbols exist for use by system designers. Nor are there any proven procedures to improve the effectiveness of screen designs. Current design practices fail to address the underlying problem of the structural analysis of images and the communication of meaning.

This dissertation therefore investigates the nature of visual literacy in computer applications and offers a paradigmatic approach to the analysis and design of computer images as a method to increase the probability that the user will receive and interpret the intended message accurately. The proposed model includes taxonomies of the structure and organisation of visual images and a set of evaluation criteria.     

Early Voting and Campaign News Coverage

The proportion of votes cast before election day has risen steadily over the last two decades. Previous research asked how early voting has impacted voter participation. In this article, we ask how early voting has affected the flow of information to voters through the mass media. By increasing the number of days voters are able to vote, are we also increasing the number of days that candidates and campaigns continuously disseminate campaign-related information to the news media? Is news coverage of campaigns quantitatively and qualitatively different when opportunities to vote early are available and utilized? Our expectation is that early voting significantly influences the volume and nature of campaign news coverage. We study the effects of early voting on campaign news coverage of gubernatorial and Senate races in 2006 and 2008. Our findings reveal that the volume and content of campaign news coverage is significantly influenced by early voting.

Public Sector Risk Financing: Exploring the Potential Use of Weather Derivatives by Fire and Rescue Services

The floods of 2007, experienced across much of England, resulted in local authority organisations, including Fire and Rescue Services, mounting large-scale responses and incurring additional and unexpected expenditure. Although central government activated funding schemes, some local authorities fell below the thresholds set and had to absorb the additional costs. This raised a question of what alternative methods were available to allow these local authority organisations to finance such unexpected costs. Weather derivatives are widely used in certain sectors to manage the financial risk that arises from undesirable weather conditions and the objective of this research is to explore the reactions of an FRS towards the use of these financial instruments in managing additional costs, such as those arising from the 2007 floods. Our findings suggest that a combination of risk-aversion, lack of specific financial knowledge and comfort with the status quo seem set to stifle development of weather derivatives as an innovation in public sector risk financing. However, this exploratory study suggests that the method has some merit and is at least worthy of further examination.     

Majority Rule in Consensual Democracies: Explaining Political Influence in Norwegian Local Councils

Norwegian local government has traditionally been strongly rooted in the consensus ideal. When the new Local Government Act of 1992 allowed the municipalities to introduce parliamentary models and abolished the statutory requirement of qualified majority decisions in the councils, this therefore implied a significant change in the local government ideal. Even though the municipalities have been reluctant to formally adopt a parliamentary model, this paper argues that in practice a majority system is replacing the traditional consensual model, with functional roles for a governing majority and an opposition. The empirical analysis employs data on local politicians from 1994 and 1998 to test the proposition that representatives of the governing parties exert more influence on local policies than members of the opposition. Two different indicators of political influence are used: (1) the councillors' budgetary influence measured as the distance between the councillors' ideal point and the actual decision outcome, and (2) the councillors' ability to have initiatives accepted in the various local political bodies. In addition to the variable representing membership of the governing majority or the opposition, the model also controls for factors such as the representatives' formal institutional affiliation, individual characteristics and community context. Even when controlling for these determinants, the empirical results strongly support the hypothesis.     

Poderes fácticos,problemas drásticos

The article reconstructs systematically a definition analytically dense of the factual powers. By focusing on the implications factual powers in Latin America, the article inquiries into the resistance of these powers to the State of law, evidencing their propensity to promote their own private interests and impose them on society at large. On its turn, the author elaborates a diagnosis of the cultural expansion of factual powers in Mexican society, demonstrating that their influence expresses and reinforces political deficiencies, legal voids and cultural paucity, identifying the ideological preponderance of private television.     

Review of “Youth Peacebuilding: Music,Gender, and Change,” by Lesley J. Pruitt

Ten countries of Central and Eastern Europe and the Mediterranean region joined the European Union in 2004. Two more new members from southeast Europe (Bulgaria and Romania) joined in January 2007. Given the diverse range of political, economic, social, and cultural contexts of these nations, EU enlargement and integration processes have entered a new phase of complexity. In this article, I analyze the cultural policy developments in eight of the new EU member states (the Czech Republic, Estonia, Poland, Latvia, Lithuania, Hungary, Slovakia, and Slovenia), examine in detail state and nonstate cultural funding patterns, and assess the influence of EU policy—especially with regard to the Culture Program, Structural Funds, and European cultural cooperation initiatives—for its impact on cultural policy development in the new member states. Next, I discuss the new forms of pan-European cultural cooperation, focusing on the development of networks, foundation initiatives, and observatories. Finally, I explore issues in development of cultural policy in the new member states and conclude with recommendations for the future of the enlarged EU.     

Fear's Anger: Virginia Woolf's Psychology and Deliberative Democracy

In A Room of One's Own, Virginia Woolf implicitly addresses the necessary conditions for equal participation in deliberative democracy. Woolf's analysis indicates that proponents of deliberative democracy must be attentive to the angry, unconscious resistance that is part of reasoning in a deliberative system—especially when political deliberation results in a challenge to a person's identity. Woolf's solution for women writers, the material security represented by a room of one's own, can be applied to the larger problem of political deliberation as well. This leads to an expansion of the conception of substantive equality required for a deliberative democracy. Further, Woolf's insight challenges deliberative democrats to de-center capitalist economic relations. As a way of protecting the individual from the psychological dynamic Woolf describes in A Room of One's Own, deliberative democrats should advocate a non-competitive economic space for those threatened by the powerful psychological reactions to deliberation.     

A neolignan-type impurity arising from the peracid oxidation reaction of anethole in the surreptitious synthesis of 4-methoxyamphetamine (PMA)

The neolignan-type substance 2,4-dimethyl-3,5-bis(4'-methoxyphenyl) tetrahydrofuran is presented as a new forensic marker compound for the peracid oxidation of anethole. It is hypothesized that the formation of a stable intermediary carbocation in the hydrolysis reaction of anethole epoxide is not only responsible for the presence of 1,2-diols (and its esters) and 4-methoxyphenyl-2-propanone (PMP2P) but can also be the cause for the creation of this neolignan impurity due to interaction with anethole itself. Moreover, the applicability of this new forensic marker is demonstrated by its retrieval in clandestinely manufactured 4-methoxyamphetamine (PMA) preparations.
