News Media, Crime and Fear of Violence

Finland witnessed a surge in crime news reporting during the 1990s. At the same time, there was a significant rise in the levels of fear of crime reported by surveys. This research examines whether and how the two phenomena: news media and fear of violence were associated with each other. The dissertation consists of five sub-studies and a summary article. The first sub-study is a review of crime reporting trends in Finland, in which I have reviewed prior research and used existing Finnish datasets on media contents and crime news media exposure. The second study examines the association between crime media consumption and fear of crime when personal and vicarious victimization experiences have been held constant. Apart from analyzing the impact of crime news consumption on fear, media effects on general social trust are analyzed in the third sub-study. In the fourth sub-study I have analyzed the contents of the Finnish Poliisi-TV programme and compared the consistency of the picture of violent crime between official data sources and the programme. In the fifth and final sub-study, the victim narratives of Poliisi-TV s violence news contents have been analyzed. The research provides a series of results which are unprecedented in Finland. First, it observes that as in many other countries, the quantity of crime news supply has increased quite markedly in Finland. Second, it verifies that exposure to crime news is related to being worried about violent victimization and avoidance behaviour. Third, it documents that exposure to TV crime reality-programming is associated with reduced social trust among Finnish adolescents. Fourth, the analysis of Poliisi-TV shows that it transmits a distorted view of crime when contrasted with primary data sources on crime, but that this distortion is not as big as could be expected from international research findings and epochal theories of sociology. Fifth, the portrayals of violence victims in Poliisi-TV do not fit the traditional ideal types of victims that are usually seen to dominate crime media. The fact that the victims of violence in Poliisi-TV are ordinary people represents a wider development of the changing significance of the crime victim in Finland. The research concludes that although the media most likely did have an effect on the rising public fears in the 1990s, the mechanism was not as straight forward as has often been claimed. It is likely that there are other factors in the fear-media equation that are affecting both fear levels and crime reporting and that these factors are interactive in nature. Finally, the research calls for a re-orientation of media criminology and suggests more emphasis on the positive implications of crime in the media.

Missile battery placement for air defense: A dynamic programming approach

A procedure to evaluate surface-to-air missile battery placement patterns for air defense is presented. A measure of defense effectiveness is defined as a function of kill probability of the defense missiles and the nature of the surrounding terrain features. The concept of cumulative danger index is used to select the best path for a penetrating hostile aircraft for any given pattern of placement. The aircraft is assumed to be intelligent and well-informed. The path is generated using a dynamic programming methodology. The software package so developed can be used off-line to choose the best among a number of possible battery placement patterns.

Promiscuous restriction is a cellular defense strategy that confers fitness advantage to bacteria

Most bacterial genomes harbor restriction-modification systems, encoding a REase and its cognate MTase. On attack by a foreign DNA, the REase recognizes it as nonself and subjects it to restriction. Should REases be highly specific for targeting the invading foreign DNA? It is often considered to be the case. However, when bacteria harboring a promiscuous or high-fidelity variant of the REase were challenged with bacteriophages, fitness was maximal under conditions of catalytic promiscuity. We also delineate possible mechanisms by which the REase recognizes the chromosome as self at the noncanonical sites, thereby preventing lethal dsDNA breaks. This study provides a fundamental understanding of how bacteria exploit an existing defense system to gain fitness advantage during a host-parasite coevolutionary ``arms race.''

Diverse functions of restriction-modification systems in addition to cellular defense

Restriction-modification (R-M) systems are ubiquitous and are often considered primitive immune systems in bacteria. Their diversity and prevalence across the prokaryotic kingdom are an indication of their success as a defense mechanism against invading genomes. However, their cellular defense function does not adequately explain the basis for their immaculate specificity in sequence recognition and nonuniform distribution, ranging from none to too many, in diverse species. The present review deals with new developments which provide insights into the roles of these enzymes in other aspects of cellular function. In this review, emphasis is placed on novel hypotheses and various findings that have not yet been dealt with in a critical review. Emerging studies indicate their role in various cellular processes other than host defense, virulence, and even controlling the rate of evolution of the organism. We also discuss how R-M systems could have successfully evolved and be involved in additional cellular portfolios, thereby increasing the relative fitness of their hosts in the population.

O papel da inteligência no combate ao crime organizado transnacional

Apresenta as linhas gerais da estrutura da comunidade de inteligência brasileira e das possibilidades de emprego dos órgãos de inteligência do Brasil no combate ao crime organizado transnacional. Identifica aspectos desse tipo de crime que podem ser neutralizados através da atividade de inteligência. Aborda os seguintes tópicos: origens e desenvolvimento do crime organizado; crimes que alimentam o crime organizado; as atividades do Sistema Brasileiro de Inteligência (SISBIN) e suas necessidades.

How much efficiency gains and price reductions for an efficiency defense? 'Quanto Basta'

Potential efficiency gains due to a merger can be used by competition authorities to judge upon proposed mergers. In a world where agents’ efforts, observable or unobservable, affect the success of a production cost reducing project that may be conducted as a stand-alone firm or in a merger, we characterize the merger decision and the type of errors a competition authority may make when it relies on an efficiency defense. In addition, we show that the occurrence of either type of errors is always smaller under the unobservable efforts assumption, than under the observable efforts one.

Antioxidant defense system and family environment in adolescents with family history of psychosis

[EN] Our objective was to determine antioxidant defence activity in healthy controls (HC) and healthy unaffected second-degree relatives of patients with early onset psychosis (HC-FHP),and to assess its relationship with familiar environment measured using the Family Environment Scale (FES). Methods: We included 82 HC and 14 HC-FHP aged between 9 and 17 years. Total antioxidant status,lipid peroxidation, antioxidant enzyme activities and glutathione levels were determined in blood samples. Results:There was a significant decrease in the total antioxidant level in the HC-FHP group compared with the HC group (OR = 2.94; p = 0.009), but no between-group differences in the Global Assessment of Functioning (GAF) scale scores. For the FES, the HC-FHP group had significantly higher scores in the cohesion (p = 0.007) and intellectual-cultural dimensions (p=0.025). After adjusting for these two FES dimensions, total antioxidant status remained significantly different between groups (OR = 10.86, p = 0.009).
