This thesis deals with the following questions: What do children find negative on the Internet? What counter strategies do they use? How have they developed these strategies? The method used is one-to-one online interviews and the analyses are qualitative in nature. The sample is children in grade 6 of the Swedish compulsory school, aged between 11 and 13. 104 children, 52 girls and 52 boys, from different parts of Sweden were interviewed. The media debate seems to display consensus regarding what threats the Internet poses to young people. The conclusion of this thesis is, however, that children’s views of the Internet in many ways differ from the media related adult view. The children of this study do not express a great deal of anxiety about the negative sides of the Internet. They are aware of, and can describe many downsides but these are not present in their everyday use of the Internet. Digging deeper it turns out that many children have in fact well-developed counter strategies. However, these strategies are not conscious in the sense that the children discuss them. Instead, they seem integrated in their online environment. The counter strategies have been developed by the children alone or together with peers. In some, but remarkably few, cases adults have been giving tips or teaching the children strategies. Nevertheless, the study does not paint a picture of naïve children, unable to see actual threats, but of responsible young citizens who are aware of the threats that exist in their online setting – sometimes from personal experience – and have developed methods to avoid such threats.

Arbetets art: Examensarbete i lärarutbildningen, Avancerad nivå, 15 hp Högskolan i Skövde Titel: Nolltolerans i skolan om hot och våld - En studie om rektorers tolkning av begreppet nolltolerans Sidantal: 41 Författare: David Löfving och Joakim Petersson Handledare: Kennert Orlenius Datum: januari, 2009 Nyckelord: nolltolerans, hot och våld, åtgärder, gränsdragning, agerande I USA på 1990-talet infördes en lag gällande nolltolerans mot vapen i skolan. Denna lag har fått en vidare tolkning vilket har gjort att många elever har blivit exkluderade från undervisningen av märkliga skäl. Uppsatsen handlar om rektorers syn på begreppet nolltolerans i frågor om hot och våld mot skolpersonal. Vidare redogör studien för hur rektorer arbetar förebyggande och hur deras efterarbete ser ut. Dessutom berör studien rektorers erfarenheter kring hot och våld mot skolpersonal. För att nå fram till studiens syfte så intervjuades rektorer på högstadieskolor. De intervjuade rektorerna hade inga större erfarenheter kring hot och våld mot skolpersonal. Rektorerna är positivt inställda till nolltoleransbegreppet dock så ser de en viss svårighet till att införa ett sådant begrepp. Allting handlar om gränsdragningar, var går gränsen för hot och våld? Rektorerna ger också uttryck för det förebyggande arbetet i undervisningen. Det finns handlingsplaner på samtliga av de intervjuade rektorernas arbetsplatser som både tar upp förebyggande och efterföljande arbete kring hot och våld.

A Transaction Reproduction System (ARTSY) is a distributed system that enables secure transactions and reproductions of digital content over an insecure network. A field of application is reproductions of visual arts: A print workshop could for example use ARTSY to print a digital image that is located at a remote museum. The purpose of this master thesis project was to propose a specification for ARTSY and to show that it is technically feasible to implement it. An analysis of the security threats in the ARTSY context was performed and a security model was developed. The security model was approved by a leading computer security expert. The security mechanisms that were chosen for the model were: Asymmetric cryptology, digital signatures, symmetric cryptology and a public key registry. A Software Requirements Specification was developed. It contains extra directives for image reproduction systems but it is possible to use it for an arbitrary type of reproduction system. A prototype of ARTSY was implemented using the Java programming language. The prototype uses XML to manage information and Java RMI to enable remote communication between its components. It was built as a platform independent system and it has been tested and proven to be operational on the Sun Solaris platform as well as the Win32 platform.

Syftet med föreliggande projekt är att kartlägga vilka förutsättningar unga erhålls i Södertälje kommun i förhållande till mänskliga rättigheter. Med detta söka nå en förklaring till de motsättningar som föreligger kommunen för att på sikt minska dem, genom att arbeta konkret med implementering av mänskliga rättigheter och eventuella resurser. Metoden för detta antagande har varit av kvalitativ karaktär, med djupintervjuer av 15 informanter. Urvalsgruppen är rektorer, lärare och elever av blandad ålder, etnicitet, kön och funktionsnedsättning. Resultatet har visat att mänskliga rättigheter inte förekommer konkret i undervisningen bland skolorna i Södertälje, dock är de ofta integrerad i undervisningen över lag. Lärare upplever att resurserna är av bristfällig natur, vilket påverkar arbetet med att tillgodose gedigen utbildning. Elever råder bristande kunskaper gällande mänskliga rättigheter och efterfrågar ökad kunskap och acceptans från lärare och andra institutioner så som kommunala verksamheter. Förutsättning för lärare att arbeta efter mänskliga rättigheter kritiseras, dels på grund av resursbrist, men även på grund av kunskapsluckor i ämnet. Kommunen bör ålägga större insatser och resurser för att se till att rättigheterna följs och implementeras i skolverksamheterna. Det råder olika kunskapsnivåer bland eleverna i kommunen, liksom hot och diskriminering, vilka ej tillgodoses i den mån som krävs, därav efterlevs inte mänskliga rättigheter i kommunen. / The purpose of this project is to identify what conditions young people receive in Södertälje municipality in relation to human rights. With that seek an explanation for the differences, the municipality in order to eventually reduce them, by working specifically with the implementation of human rights and possible resources. The method of this assumption has been qualitative in nature, in-depth interviews of 15 informants. Selection group are principals, teachers and pupils of mixed ages, ethnicity, gender and disability. The results have shown that human rights do not exist concretely in education among schools in Södertälje, however, they are often integrated in the teaching of law. Teachers feel that the resources of poor nature, affecting efforts to meet the decent education. Students lack of awareness regarding human rights and demand greater knowledge and acceptance from teachers and other institutions. Prerequisite for teachers to work for human rights criticism, partly because of lack of resources, but also because of gaps in knowledge on the subject. The municipality should require more effort and resources to ensure that rights are respected and implemented in school activities. There are varying levels of knowledge among students in the municipality, as well as threats and discrimination, which is not satisfied to the extent required, hence not observed human rights in the municipality.

This thesis aims to discuss the Collective Security Treaty Organization (CSTO) and the sources of Russia&rsquo / s influence over its other member-states. It focuses on the origins of the CSTO and the development of security cooperation within the CSTO framework. The thesis argues that although the CSTO continues to be a Russia-centric regional security organization, Russia&rsquo / s influence over the other CSTO member states has been gradually limited throughout the 2000s due to the increasing diversity in the threat perception of the other CSTO member states and the increasing penetration of the other regional security organizations into the post- Soviet space. Following the Introduction chapter, the second chapter discusses the origins of security cooperation within the framework of the CIS. The third chapter analyzes the CSTO in terms of its structure and activities since its establishment in 2002. The next chapter outlines the transnational challenges to the security of the post-Soviet states and their threat perception, as well as the efforts to promote regional security by the regional actors. The fifth chapter analyzes the increasing involvement of other regional security organizations, such as SCO, OSCE, and NATO into the post-Soviet space. The concluding chapter discusses the main finding of the thesis.

In a more complex and interdependent world, nations face new challenges that threaten their national security. National security should not be understood exclusively in the way of military threats by adversarial states but in a broader way: how old and new sectoral threats affect not only a state and its institutions but a nation as a whole, physically and economically. This dissertation looks into how the nature of security threats and risks has evolved in recent years. This dissertation then explores how different nations have decided to publish national security strategy documents and analyzes the way in which they include this broadened understanding of security: it finds that there is evidence of international policy diffusion related to the publication of such security strategies and that nations are evolving towards a broader understanding of security that includes models like whole-of-government, and whole-of-society. In the second half, this dissertation analyzes the route through which Mexico has reformed its national security framework since the year 2000 through a policy streams approach. After looking at the path that led to the creation of Mexico’s modern national security institutions, it analyzes the way in which Mexico national interests can be determined and how these interests inform the way in which Mexico understands national security threats and risks in the 21st Century. / text

At first glance, the very idea of analysing the freedom of the media and of researching censorship in Switzerland seems absurd. After all, the Federal Constitution explicitly guarantees freedom of the media, and censorship is forbidden. Furthermore, this small, federal, multilingual and multicultural landlocked country in the middle of Europe is universally praised as a model of democracy. Indeed, in a country whose people have a far greater say in government than anywhere else, one could easily assume that the freedom of the media is a foregone conclusion. Yet, in reality, this shining image is more than a little tarnished. The "Prototype for Europe" – as the former Federal President of Germany Richard von Weizsäcker once described Switzerland – experiences the same forms and mechanisms of censorship as any other democratic country. Of course, in Switzerland "undesirable" journalists are not threatened with murder, but critically discerning authors do risk becoming social outcasts. Switzerland prohibits governmental pre-censorship, but the advertising industry has on occasion attempted to shape the content of the media by means of post-publication censorship in the form of boycotts. Switzerland is a constitutional state, yet the paragraphs of its penal and civil codes hang over media workers like the sword of Damocles. Then there are structural problems such as the lack of proper journalistic education. However one looks at it, the freedom of the media in Switzerland is officially, materially and structurally restricted. However, most people remain unconcerned by and indeed unaware of this state of affairs. Thomas Jefferson's reminder that, "to preserve the freedom of the human mind then and freedom of the press, every spirit should be ready to devote itself to martyrdom; for as long as we may think as we will, and speak as we think, the condition of man will proceed in improvement”*, has long been forgotten in Switzerland. The Swiss appear to be basking in their country’s reputation as a place without media problems. It therefore came as no surprise to us when, both in our quantitative and qualitative research, many of those interviewed were surprised and even irritated at our 2 questions about possible threats to freedom of the media in Switzerland. Some people even felt that they were being personally attacked and responded along the lines that "Instead of fouling our own nest we ought to describe the advantages of our country and our democratic system". Or: "In comparison with Russia or China we are living in a paradise": It seems that only the most critical among the media personnel, media experts and media scientists are willing to pinpoint the problems faced by the contemporary Swiss media. All the others are convinced that we have the best media on earth. This attitude of part indifference, part ignorance and part wishful thinking, was the catalyst for our research on the freedom of the Swiss media and the potential dangers and mechanisms which threaten it. Our findings reveal that all that glitters is not gold and that the Swiss media scene is, in some ways, reminiscent of a Potemkin village. *Jefferson, Thomas, Letter to William Green Mumford, 18 June 1799 (http://www.positiveatheism.org/hist/quotes/jefferson.htm, consulted 15 June 2006)

Using a comparative approach, the presented study explores the ecology of ten species of native New Zealand broom, Carmichaelia, and their vulnerability to competition and herbivory, with the aim of gaining a better understanding of the significance of introduced species as a threat to rare indigenous plants in New Zealand. In particular, the study focuses on the relationship between characteristics of the Carmichaelia species and their vulnerability, as well as on other factors influencing the significance of introduced species as a threat. To gain a better understanding of the ecology of the Carmichaelia species, their current habitats and associated plant communities were investigated using quantitative-descriptive methods in the field. The effect of competition with introduced plants was studied in two glasshouse experiments, differentiating above ground competition for light from below ground competition for nutrients and water. The experiments focussed on the early life-stage of seedling establishment of the Carmichaelia species. The impact of herbivory by introduced mammals was studied in four field-based exclosure trials, focussing on the effects on survival and reproductive activity of adult Carmichaelia plants. The results showed that the effects of competition and herbivory vary between the different species. Furthermore, they provided a set of species characteristics that can be used as indicators to predict the vulnerability of Carmichaelia to the impact of introduced species. These indicators provide a useful tool for threatened species management, as they allow the identification of the most vulnerable species as well as the most significant threat to each species. Furthermore, the indicators can be used to group species, combining those with similar vulnerability profiles, and therefore, likely similar management needs. However, the example of the Carmichaelia species also illustrated that the use of indicators for the vulnerability of threatened species is limited and needs to be combined with case-by-case studies to verify the actual significance of threats for each population of concern. The vulnerability profiles derived from species’ characteristics can be used to guide such site specific studies, ensuring they focus on the most relevant threat factors. This combination of the understanding of general patterns in the vulnerability of species with targeted species and site-specific studies will lead to increased efficiency in the conservation management of threatened plant species.

Att arbeta med utsatta människor i en statlig verksamhet som tjänsteman kan för de flesta människor verka ofarligt – men hur är det egentligen? Tidigare forskning har visat att det finns ett stort mörkertal när det kommer till klientrelaterat hot och våld och att incidenterna inte tas tillräckligt seriöst. Syftet med denna uppsats är att få en större förståelse för vad de ökade hoten får för konsekvenser för personalen på Migrationsverket. Vi vill belysa och synliggöra spänningsfältet i klientrelationen som leder till att hot och våld mot handläggare ökar. Det teoretiska ramverk som används i uppsatsen är gräsrotsbyråkrati, makt och klientrelationer. Genom sex semistrukturerade intervjuer med handläggare på Migrationsverket har vi fått fram underlag som visar att hot och våldssituationer förekommer i större omfattning än vad det anmäls och rapporteras om. Resultatet visade att mörkertalet är stort vid incidentrapporteringen och att det råder en ”det kommer med jobbet”-mentalitet bland personalen. Maktfördelningen har en stor roll i klientrelationen och är en bidragande orsak till att incidenter uppstår. Vidare visar det sig att negativa beslut är de som tenderar att utlösa hot eller våld från klienten och att det väldigt sällan rapporteras kring eller anmäls om inte klienten tar till fysiskt våld. Slutligen visar uppsatsen att förebyggande arbete måste ske i en större omfattning. / Working with vulnerable people in a government controlled authority may for most people seem harmless - but is it really? Previous research has shown that there is large hidden statistics when it comes to client-related threats and violence and that the incidents are not taken seriously enough. The purpose of this paper is to gain a greater understanding of what the increased threats and violence towards officials in a government controlled authority can lead to. We want to shed visibility over the attributes in the client relationship that leads to threats and violence against the government officials. The theoretical framework used in the paper is street-level bureaucracy, power, and client relationships. We have performed six semi-structured interviews with officials from the Swedish Migration board, which have shown that threats and violence towards government officials occur to a greater extent than it is shown and reported on. The results showed that the hidden statistics is large in incident reporting and that there is a "it comes with the territory" mentality among officials. The distribution of power has a major role in client relationships and is a contributing factor to incidents occurring. Furthermore, it turns out that negative decisions are the ones that tend to trigger threats or violence from the client and that it is rarely reported unless the client resorts to physical violence. Finally, the paper shows that prevention work must be done on a larger scale.
