Accountability and corruption : a study into political institutions as referees between principals and agents

Representativ demokrati innebär att medborgare istället för att själv göra beslut i frågor som angår dem, ofta delegerar dylikt beslutsfattande till representanter. Det här betyder att viktiga beslut görs av personer som medborgarna i allmänhet inte känner speciellt väl, och i vars ageranden medborgarna endast har lite insyn. Vanliga medborgare och deras representanter har därtill ofta mycket olika intressen, d.v.s. har olika syn på vad som är viktigt. Representanterna har följaktligen både möjligheter och incitament att missbruka den makt som anförtrotts dem, bl.a. genom korrupt verksamhet. Denna avhandling analyserar mekanismer genom vilka korruption bland representanter kan förebyggas, och (då korrupta handlingar redan ägt rum) upptäckas. Avhandlingen granskar mekanismer som a) ger medborgare och andra ansvarsutkrävare mer information om representanternas målsättningar och ageranden, b) som tvingar representanterna att rättfärdiga sina ageranden gentemot medborgare och andra ansvarsutkrävare, och c) som gör det möjligt för medborgare och andra ansvarsutkrävare att straffa representanter som agerat korrupt. Avhandlingen hävdar att tillämpandet av dylika mekanismer minskar lockelsen för och möjligheterna att engagera sig i korrupta handlingar. Avhandlingen studerar de mekanismer för ansvarsutkrävande som skapas genom politiskt institutionsbyggande. Bl.a. analyseras i vilken grad olika valsystem och typer av maktfördelning gör det möjligt att hålla representanter till svars, och därmed förhindra och upptäcka korruption. Sambandet mellan institutionsbyggande, möjligheter till ansvarsutkrävande och förekomst av korruption studeras på såväl makro- som mikronivå. Studien på makronivå inkluderar ett flertal länder och analyserar sambandet med hjälp av statistisk analys. Studien på mikronivå däremot består av två fallstudier (Österrike och Botswana) och utgör en djupdykning i dessa länders politiska institutioner, möjligheter till ansvarsutkrävande inom ramen för institutionerna, och följder i form av korruption.

Political ideologies and attitudes towards income inequality in the US: a critical discourse analysis of CNN and Fox News opinion articles

The topic of the thesis is media discourse about current state if income inequality in the US, and political ideologies as influences behind the discourse. The data consists of four opinion articles, two from CNN and two from Fox News. The purpose of the study was to examine how media represents income inequality as an issue, and if the attitudes conveyed are concerned or indifferent. Previous studies have indicated that the level of income is often seen as a personal responsibility, and such perspective can be linked with Republican ideology. In contrast, the Democrats typically express more concern about the consequences of inequality. CNN has been previously considered to have a Democratic bias, and Fox News has been considered to have Republican bias, which is one reason why these two news channels were chosen as the sources of the data. The study is a critical discourse analysis, and the methods applied were sociocognitive approach, which analyzes the social and cognitive factors affecting the discourse, and appraisal framework, which was applied to scrutinize the expressed attitudes more closely by identifyind specific linguistic features. The appraisal framework includes studying such features as affect, judgment and appreciation, which offer a more detailed analysis on the attitudes present in the articles. The sociocognitive approach, additionally, offers a way of analyzing a more broad context affecting the articles. The findings were then compared, to see if there are differences between the articles, or between the news sites with alleged bias. The findings showed that CNN, with alleged Democratic bias, had a more symphatetic attitude towards income inequality, whereas Fox News, with more Republican views, showed clearly less concern towards the issue. Moreover, the Fox News articles had such dubious claims that the underlying ideology behind the articles could be even supporting of income inequality, as it allows the rich to pursue all the wealth they can without having to give anything away. The results, thus, suggest that the political ideologies may a significant effect on media discourse, which, in turn, may have a significant effect on the attitudes of the public towards great issues that could require prompt measures.

POLITICAL ENVIRONMENT AND BUSINESS DEVELOPMENT IN THE ARCTIC Strategic opportunities and threats for Finnish companies

The Arctic environment is changing constantly. There are several factors that constitute to the rate and immensity of the development. The region differs from the surrounding markets that most of the countries in the region have been used to. Therefore the purpose of the study was to understand how the political environment affects Finnish companies’ strategies and business operations. The issues analyzed were the political environment in the region, the business environment and economic development, and the opportunities and threats that the Finnish companies have in Arctic. The main theories were found from strategic management and market analysis tools. The different theories and definitions were gone through in order to understand the context of the study. This is a qualitative study that uses content analysis as its main method of analyzing the data. Therefore the data analyzed was gathered from already existing material and it was analyzed until the saturation point was found. This was done in order to minimize the risks related to using secondary data. The data collected was then categorized into themes accordingly. First the general political environment in the Arctic was studied, especially the Arctic Council and its work as the main political entity. From there the focus shifted to the business environment and the general opportunities and threats that are found from Arctic economic development. China offered another point of view to this as it represented a non-Arctic state with a keen interest on the region. Lastly the two previous objectives were combined and looked through from a Finnish perspective. Finnish companies have a great starting point to Arctic business and the operational business environment gives them the framework with which they have to operate in. As a conclusion it can be said that there are three main factors leading the Arctic economic development; the climate change, the development of technology, and the political environment. These set the framework with which the companies operating in the region must comply with. The industry that is likely to lead the development is the marine industry. Furthermore it became evident that the Finnish companies operating in the Arctic face many opportunities as well as threats which can be utilized, taken advantage of or controlled through effective strategic management. The key characteristics needed in the region are openness and understanding of the challenging environment and the ability to face and manage the arising challenges.

Logging residues from regeneration fellings for biofuel production - a GIS-based availability and supply cost analysis

Finland has large forest fuel resources. However, the use of forest fuels for energy production has been low, except for small-scale use in heating. According to national action plans and programs related to wood energy promotion, the utilization of such resources will be multiplied over the next few years. The most significant part of this growth will be based on the utilization of forest fuels, produced from logging residues of regeneration fellings, in industrial and municipal power and heating plants. Availability of logging residues was analyzed by means of resource and demand approaches in order to identify the most suitable regions with focus on increasing the forest fuel usage. The analysis included availability and supply cost comparisons between power plant sites and resource allocation in a least cost manner, and between a predefined power plant structure under demand and supply constraints. Spatial analysis of worksite factors and regional geographies were carried out using the GIS-model environment via geoprocessing and cartographic modeling tools. According to the results of analyses, the cost competitiveness of forest fuel supply should be improved in order to achieve the designed objectives in the near future. Availability and supply costs of forest fuels varied spatially and were very sensitive to worksite factors and transport distances. According to the site-specific analysis the supply potential between differentlocations can be multifold. However, due to technical and economical reasons ofthe fuel supply and dense power plant infrastructure, the supply potential is limited at plant level. Therefore, the potential and supply cost calculations aredepending on site-specific matters, where regional characteristics of resourcesand infrastructure should be taken into consideration, for example by using a GIS-modeling approach constructed in this study.

Investigation and data adaptive analysis of CARS spectra

In this diploma work advantages of coherent anti-Stokes Raman scattering spectrometry (CARS) and various methods of the quantitative analysis of substance structure with its help are considered. The basic methods and concepts of the adaptive analysis are adduced. On the basis of these methods the algorithm of automatic measurement of a scattering strip size of a target component in CARS spectrum is developed. The algorithm uses known full spectrum of target substance and compares it with a CARS spectrum. The form of a differential spectrum is used as a feedback to control the accuracy of matching. To exclude the influence of a background in CARS spectra the differential spectrum is analysed by means of its second derivative. The algorithm is checked up on the simulated simple spectra and on the spectra of organic compounds received experimentally.

Project profitability is approached starting from managing projects, continuing to project pricing process and concluding to project success. The empirical part of this study describes the Case Company’s project portfolio, and by means of quantitative analysis, the study describes how the characteristics of a project impact the project’s profitability. The findings indicate that it really makes a difference in project portfolio’s estimated and actual profitability when methods of installation and technical specifications are scrutinized. Implications on profitability are gathered into a risk assessment tool proposal.

Intrapartum hypoxia and power spectral analysis of fetal heart rate variability

Reliable detection of intrapartum fetal acidosis is crucial for preventing morbidity. Hypoxia-related changes of fetal heart rate variability (FHRV) are controlled by the autonomic nervous system. Subtle changes in FHRV that cannot be identified by inspection can be detected and quantified by power spectral analysis. Sympathetic activity relates to low-frequency FHRV and parasympathetic activity to both low- and high-frequency FHRV. The aim was to study whether intra partum fetal acidosis can be detected by analyzing spectral powers of FHRV, and whether spectral powers associate with hypoxia-induced changes in the fetal electrocardiogram and with the pH of fetal blood samples taken intrapartum. The FHRV of 817 R-R interval recordings, collected as a part of European multicenter studies, were analyzed. Acidosis was defined as cord pH ≤ 7.05 or scalp pH ≤ 7.20, and metabolic acidosis as cord pH ≤ 7.05 and base deficit ≥ 12 mmol/l. Intrapartum hypoxia increased the spectral powers of FHRV. As fetal acidosis deepened, FHRV decreased: fetuses with significant birth acidosis had, after an initial increase, a drop in spectral powers near delivery, suggesting a breakdown of fetal compensation. Furthermore, a change in excess of 30% of the low-to-high frequency ratio of FHRV was associated with fetal metabolic acidosis. The results suggest that a decrease in the spectral powers of FHRV signals concern for fetal wellbeing. A single measure alone cannot be used to reveal fetal hypoxia since the spectral powers vary widely intra-individually. With technical developments, continuous assessment of intra-individual changes in spectral powers of FHRV might aid in the detection of fetal compromise due to hypoxia.

Abraham Bar Hiyya on time, history, exile and redemption : an analysis of Megillat ha-Megalleh

Megillat ha-Megalleh av Abraham bar Hijja (Spanien, 12. årh.) är bäst känd som en samling av messianska beräkningar. Men boken som helhet innehåller, vid sidan om beräkningarna, varierande innehåll såsom filosofi, bibeltolkning och astrologi. Bar Hijja framför en argumentering, inför det växande inflytandet på judarna från de kristna, för att den judiska religionen, och särskilt judarnas väntan på den messianska tiden, fortfarande är giltiga. Bar Hijja utvecklar, med hjälp av den judiska traditionen, arabiska vetenskapliga och andra källor samt omdefinierade kristna ideér, en syn på historien som en determinisk händelselopp som består av goda och dåliga tider men eventuellt skall kulminera i en messiansk tid för judarna. Boken innehåller även en omfattande astrologisk kommentar på historien, som bland annat beskriver uppkomsten och historien av de kristna och muslimska världsmakterna, samt deras förhållanden med judar. Boken är tydligt avsett att övertyga judarna att förbli judar, genom att argumentera med hjälp av både judiskt och ickejudiskt material, att oavsett läget i exil har de den framtid som de väntat för. I det medeltida sammanhanget syns detta inte enbart som en religiös fråga utan också som en politisk strävan till att säkerställa det judiska samfundets framtid.

Search and Paper SKU Analysis of Recipes Meeting EUPS Standard

The theoretical research of the study concentrated on finding theoretical frameworks to optimize the amount of needed stock keeping units (SKUs) in manufacturing industry. The goal was to find ways for a company to acquire an optimal collection of stock keeping units needed for manufacturing needed amount of end products. The research follows constructive research approach leaning towards practical problem solving. In the empirical part of this study, a recipe search tool was developed to an existing database used in the target company. The purpose of the tools was to find all the recipes meeting the EUPS performance standard and put the recipes in a ranking order using the data available in the database. The ranking of the recipes was formed from the combination of the performance measures and price of the recipes. In addition, the tool researched what kind of paper SKUs were needed to manufacture the best performing recipes. The tool developed during this process meets the requirements. It eases and makes it much faster to search for all the recipes meeting the EUPS standard. Furthermore, many future development possibilities for the tool were discovered while writing the thesis.

Liquidity levels of Finnish SME’s from 2007 to 2013 and a closer analysis of the IC sector

TAVOITTEET: Tämän tutkielman tarkoitus on tarkastella eri toimialojen likviditeettitasoja vuosien 2007 ja 2013 välillä. Se tarkastelee myös kassanhallinnan ja likviditeetin kirjallisuutta, erilaisia likviditeettiä kuvaavia tunnuslukuja sekä asioita, joilla on vaikutusta likviditeettiin. Tämän lisäksi se tutkii informaatio ja kommunikaatio sektoria tarkemmin. DATA: Data on kerätty Orbis tietokannasta. Toimialakohtaiset keskiarvot on laskettu joko kappaleen 2 esittämillä kaavoilla tai noudettu suoraan tietokannasta. Hajonta kuvaajat on tehty Excelillä ja korrelaatio matriisi ja regressioanalyysit SAS EG:llä. TULOKSET: Tämä tutkimus esittää toimialakohtaiset keskiarvot liquidity ratiosta, solvency ratiosta sekä gearingista, kuten monista muista likviditeettiä kuvaavista tai siihen vaikuttavista tunnusluvuista. Tutkimus osoittaa, että keskimäärin likviditeetti ja maksuvalmius ovat säilyneet melko samana, mutta toimialakohtaiset muutokset ovat voimakkaita. IC sektorilla likviditeettiin vaikuttaa katetuotto, työntekijöiden määrä, liikevaihto, taseen määrä sekä maksuaika.
