Effects of a Financial Transaction Tax - Do Transaction Costs Lower Volatility?: A Literature Review

In this literature review the theorethical framework of Financial transaction taxes and their assumed effect on market volatility is assessed. The empirical evidence from various studies is compared against the theory and a simple empirical review of the Finnish stock market is conducted. The findings implicate that financial transaction taxes can not reduce volatility and their actual effect on markets is dependend by many other factors as well. Some evidence even suggests that transactions taxes may actually raise volatility.

A systematic literature review on agile project

In the 21st century, agile project management (APM) has emerged as a major evolutionary step in the area of software project management. APM is defined as a conceptual framework, consisting of various methods such as Scrum, quick respond to change, better customer collaboration, minimum coverage of documentation and extreme programming (XP) that facilitates to produce working software in multiple iterations with team work. Because agile project management has become more popular in the software industry in recent years, it constitutes an interesting and comprehensive research topic. This thesis presents a systematic literature review (SLR) of published research articles concerning agile project management. Based on a predefined search strategy, 273 such articles were identified, of which 44 were included in the review. The selected 44 articles were published between years 2005 and 2012. The thesis defines a review process by developing a review protocol and presenting the results of the review. The results are expected to provide researchers, software man

GIS assessing traditional and modern agricultural land use/land cover change. A case study 1959-2005: Rekijoki, Somero, SW-Finland

Finland’s rural landscape has gone through remarkable changes from the 1950’s, due to agricultural developments. Changed farming practices have influenced especially traditional landscape management, and modifications in the arable land structure and grasslands transitions are notable. The review of the previous studies reveal the importance of the rural landscape composition and structure to species and landscape diversity, whereas including the relevance in presence of the open ditches, size of the field and meadow patches, topology of the natural and agricultural landscape. This land-change study includes applying remote sensed data from two time series and empirical geospatial analysis in Geographic Information Systems (GIS). The aims of this retrospective research is to detect agricultural landscape use and land cover change (LULCC) dynamics and discuss the consequences of agricultural intensification to landscape structure covering from the aspects of landscape ecology. Measurements of LULC are derived directly from pre-processed aerial images by a variety of analytical procedures, including statistical methods and image interpretation. The methodological challenges are confronted in the process of landscape classification and combining change detection approaches with landscape indices. Particular importance is paid on detecting agricultural landscape features at a small scale, demanding comprehensive understanding of such agroecosystems. Topological properties of the classified arable land and valley are determined in order to provide insight and emphasize the aspect the field edges in the agricultural landscape as important habitat. Change detection dynamics are presented with change matrix and additional calculations of gain, loss, swap, net change, change rate and tendencies are made. Transition’s possibility is computed following Markov’s probability model and presented with matrix, as well. Thesis’s spatial aspect is revealed with illustrative maps providing knowledge of location of the classified landscape categories and location of the dynamics of the changes occurred. It was assured that in Rekijoki valley’s landscape, remarkable changes in landscape has occurred. Landscape diversity has been strongly influenced by modern agricultural landscape change, as NP of open ditches has decreased and the MPS of the arable plot has decreased. Overall change in the diversity of the landscape is determined with the decrease of SHDI. Valley landscape considered as traditional land use area has experienced major transitional changes, as meadows class has lost almost one third of the area due to afforestation. Also, remarkable transitions have occurred from forest to meadow and arable land to built area. Boundaries measurement between modern and traditional landscape has indicated noticeable proportional increase in arable land-forest edge type and decrease in arable land-meadow edge type. Probability calculations predict higher future changes for traditional landscape, but also for arable land turning into built area.

Arseeni ja elohopea maaperässä ja vesistöissä

Maapallon väestön kasvaessa ja tarpeen makealle vedelle, ruualle ja viljelymaalle noustessa on tärkeää alkaa kiinnittää entistä tarkemmin huomiota vesistöjen ja maaperän saastumiseen myrkyllisillä raskasmetalleilla. Erityisesti elohopea ja arseeni, jotka jo nyt vaikuttavat heikentävästi miljoonien ihmisten elämään eri puolilla maapalloa, on syytä ottaa huolelliseen tarkkailuun. Raskasmetallien päästölähteet voidaan jakaa kahteen luokkaan, luonnollisiin ja ihmisperäisiin. Ihmisperäisiin päästölähteisiin voidaan vaikuttaa muun muassa teollisuutta ja liikennettä koskevalla lainsäädännöllä. Luonnollisiin päästölähteisiin vaikuttaminen on huomattavasti haastavampaa, mutta niiden haittaa ihmisille on mahdollista pienentää muun muassa parempien vedenpuhdistustekniikoiden avulla. Tämän työn kirjallisuusosassa tullaan esittelemään erityyppisiä luonnossa esiintyviä arseenin ja elohopean yhdisteitä, suurimpia arseenin ja elohopean päästölähteitä, sekä näiden raskasmetallien haitallisia terveysvaikutuksia. Kokeellisessa osassa tullaan keskittymään arseenin analysointiin nestemäisistä näytteistä. Näytteinä käytettiin tuntemattomilta kaatopaikoilta otettuja suotovesinäytteitä, sekä Pien-Saimaan pintavesinäytteitä. Analyyseihin on käytetty ICP-AES laitteistoa sekä kapillaarielektroforeesia.
