An efficient market implies that the use of fundamental analysis should not result in excess return, and that any return exceeding the market average can be explained by compensation for risk, accord-ing to The Capital Asset Pricing Model (CAPM). The focus of this study is to test whether the suc-cessful investment strategy developed by Piotroski (2000) generates excess return on American data, after risk adjustment by using Fama & French?s (1993) 3-factor and Carhart?s (1997) 4-factor CAPM. Initially we form stock portfolios based on companies characterized by high book-to-market values, additionally, we divide them into different performance classes by ranking them with Piotroski?s (2000) measure of financial performance, F_SCORE.

In recent years, awareness of the climate change has increased around the world. Environmental issues have been taking into consideration, both by individuals and companies. Therefore the demands for new environmental friendly technology have increased, also known as cleantech. To further establish and develop cleantech it requires capital. Venture capitalists have as well seen the potential.To increase the number of Venture capital investments in cleantech, it is important the investments generate good returns.

In this thesis we compare how different strategies in choosing attribute values affects junk mail filtering. We used two different variants of a naïve Bayesian junk mail filter. The first variant classified an e-mail by comparing it to a feature vector containing all attribute values that were found in junk mails in the part of the e-mail collection we used for training the filter. The second variant compared an e-mail to a feature vector that consisted of the attributes that was found in ten or more junk mails in the part of the e-mail collection we used for training the filter. We used an e-mail collection that consisted of 300 e-mails, 210 of these were junk mails and 90 were legitimate e-mails.

Hidden away in the pristine landscape on the northeast shore of the Dominican Republic, the remote village of Miches is on the verge of shifting its economic resource base from traditional fishing into what could become an international model for sustainable tourism. The aim of this thesis was to produce a vision of a waterfront park near the center of the village; demonstrating concept-based landscape design that reflects the goals of sustainable development originating from the local incentive structure. A composite landscape analysis and design concept both served to inform and guide the design work, which was executed through model building, hand drawings, and production of a visual presentation in the format of an architectural competition entry. The design concept, All invited, signifies the distinction between the development that is about to take place in Miches and the otherwise common all-inclusive resorts, where tourists are set apart from the local community and spend most of their time within the fenced-off premises of the hotel. All invited also captures the typical Dominican hospitality, and mirrors the aspirations of turning Miches into a safe and welcoming place for visitors. The result is a public park design that is equally inviting local residents as it is to tourists, and where the unique qualities of the site are emphasized without being exploited.

In this Masters thesis we investigate query expansion using an electronic thesaurus. We formed 30 topics from the library and information science field. For each topic three searches were made in the bibliographic database LISA Library and Information Science Abstracts via CSA Cambridge Scientific Abstracts. LISA has an electronic thesaurus attached. We used this thesaurus to form baseline queries, baseline queries expanded with synonyms, and baseline queries expanded with both synonyms and related terms.

The purpose of my study is to find out which way the extended school staff has their knowledge about conflicts, what they think is the cause of a conflict and how they handle conflicts.To answer these questions, I have chosen to do interviews with an available group. I interviewed six persons of different gender, age, nationality and they have been working from three to twenty years at afterschool care.I have analyzed my empirical material using Szklarkis four causes of a conflict and Malténs strategies for conflict management.My conclusion is that the after-school staff's knowledge is mostly based on experience, partly through work with children group in afterschool care and as a youth leader in the voluntary sector. The strategy almost always used for the after-school staff were the collusion strategy.

The purpose of this essay is to analytically review and discuss architecturalcompetitions, mainly through the general views of a few selected workinglandscape architects, architects and scientists. I have studied the moral and workethicalaspects of using graphical presentations as a mean to draw attention,rather than trying to meet the set program points.My results are derived from e-mail interviews, literature studies and studies ofthe competition entry Stockholmssfären from the competition Stockholmsportenwhich was held in Sweden early 2011.The literature studies have shown that the available literature on architecturalcompetitions and research on the subject is biased towards architecture ratherthan landscape architecture. Worth mentioning is also that there is not a lot ofavailable literature, mainly due to lacking research on the subject.The informants for the interviews were selected based upon their academicmerits and/or experience of working with or doing scientific research onarchitectural competitions. The landscape architects? opinions regardingarchitectural competitions turned out to be in many ways alike ? they seemed tohave a pretty relaxed view of competing in architecture.

The Swedish agricultural sector is currently undergoing a substantial structural change. The number of farm enterprises is continuously decreasing and the average farm size is increasing. In combination with increasing number of competitors in the insurance market, the competitive rivalry within this market has increased significantly. With this knowledge in mind, Länsförsäkringar Uppsala initiated this study, which aims to provide an understanding of customer?s view on customer value, related to agricultural insurance and financing.

This B.Sc. Thesis examines how Swedish Large Cap companies communicate CSR in social media. We describe the current state of CSR communication in four different social media channels, Twitter, Youtube, Facebook, and blogs. This research, supported by interviews with stakeholders and a quantitative survey, analyses the potential risks and benefits from communicating CSR via social media and provides concrete advice on the development of a CSR communication strategy for social media. Although some benefits have been realized, many companies have failed to truly reap the potential benefits from an effective social media strategy for CSR.

This thesis examines how the EU and Sweden aim to prevent radicalization through their strategies on preventing violent extremism (PVE). It contributes to PVE knowledge by examining how both actors plan preventive measures to combat radicalization and promote resilient societies. Analyzing Sweden's anti-terrorism strategy (Skr. 2014/15:146) and the EU strategy (COM(2020) 795 final), this study shows similarities in their approaches, particularly in targeting schools and youth with their preventive measures. Emphasis is placed on education to promote democratic and critical thinking, thus promoting resilience against radicalization.

The rise of social media has created an endless source of possibilities for companies to interact and connect with their target audiences. As it is a new channel, companies may experience uncertainty on how to use it to its fullest potential.The purpose of this study is to describe how the Public Service radio channel, P4 Kalmar, use its Facebook page and how its members perceive the communication on this platform. We have also presented recommendations on how P4 Kalmar can improve the relationship with its members. To reach our conclusions we have combined theoretical references with a quantitative content analyze, a survey and qualitative depth interviews.By analyzing our findings we came to the conclusion that P4 Kalmar have to develop a strategy for communicating on social media. But since no general communication strategy for the organization exists they have to develop one before developing one for social media.

This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.

A wish for a higher standard of living has driven the rate of consumption in Sweden. Mainfocus in business is on a higher growth and profitability where some companies use a lowprice strategy to win competitive advantage. The positive consumption pattern spiral is oftendiscussed in media, while criticism is limited and often refers to the environment. In order toreduce our ecological footprint we should consume more sustainably. More and morecompanies implement CSR (Corporate Social Responsibility) in their business strategy tobecome more sustainable.

A great source of risk during peace processes of today comes from spoilers, individuals and groups who deliberately try to undermine every attempt to achieve a negotiated peace agreement. The aim of the thesis is to examine problems related to the management of spoilers during peace negotiations and the effects thereof. A central aspect in this respect is the dilemma of whether to include or exclude controversial actors like spoilers at negotiations.The choice of limits of the subject is to examine the peace negotiations that resulted in ?The Agreement? in 1998, concerning the conflict in Northern Ireland, and in ?DOP? in 1993, concerning the conflict between Israel and Palestine. I find a significant difference between these two conflicts regarding the way of managing spoilers.

The world gets smaller and smaller and goods, services, people and information are nowadays more and more able to freely cross borders. Half of the Swedish GNP consists of export and almost 70 % of that amount is goods. Because of today?s increasing globalization the Swedish companies are now faced with both new opportunities and threats. Companies with goods which are manufactured in Sweden gets challenged by increased competition from cheap goods produced in other countries and companies can no longer afford to entirely focus on the domestic market.
