Tässä kandidaatintyössä selvitetään aurinkosähköjärjestelmän rakentamisen kannattavuutta, teknisiä ratkaisuja sekä vaatimuksia pientaloon. Tutkimus suoritetaan tarkasteltavaan kiinteistöön aurinkosähköjärjestelmän teknisten ratkaisumahdollisuuksien sekä taloudellisesti kannattavimman mallin löytämiseksi. Työssä käydään läpi järjestelmän teknisten komponenttien rakennetta ja ominaisuuksia, niille määriteltyjä vaatimuksia sekä hintaa. Työssä myös simuloidaan eri voimalakokonaisuuksien tuotantoa voimalan koon optimoimiseksi kohteelle. Saatujen tulosten perusteella voimalan hankkiminen on vielä kallista ja takaisinmaksuajat pitkiä johtuen järjestelmän kalliista hinnasta. Tulevaisuudessa aurinkosähkö tulee olemaan kannattava investointi samalla, kun yhä enenevissä määrin energistyvässä maailmassa luovutaan fossiilisista polttoaineista niiden ympäristövaikutusten ja resurssien puutteen vuoksi. Aurinkosähkö on yksi potentiaalisista korvaajista tulevaisuudessa ja voimme odottaa järjestelmien hintojen laskevan kilpailun lisääntyessä. Myös valtion tuki tulevaisuudessa on mahdollinen pientuottajillekin.

Tutkielman aiheena on suomalainen urheilujournalismi ja sen suhde itänaapuriin. Tarkoituksena on vertailla sen mahdollista muutosta Neuvostoliiton ajalta ja verrata sitä aikaan sen hajoamisen jälkeen. Vertailukohteiksi olen valinnut Calgaryn ja Soulin olympialaiset vuodelta 1988 ja Albertvillen ja Barcelonan olympialaiset vuodelta 1992 sekä Lillehammerin talvikisat vuodelta 1994. Miten urheilujournalismin painotukset ovat muuttuneet olympiauutisoinnissa? Primäärilähteenä käytän Helsingin Sanomien urheilutoimituksen olympiauutisointia ja Yleisradion Urheiluruutua sekä sen olympiauutisointia. Taustana käytän suomalaisten urheilutietokirjojen olympia-analyysejä ja yhteenvetoja kyseisistä kisoista. Käsittelen myös Ville Pernaan jakoa, jolla hän jakaa Suomen ja Neuvostoliiton suhteet ja ystävyyspolitiikan kolmeen tasoon. Tarkastelen myös yleisesti Suomen ja Neuvostoliiton suhteita, suomettumisen käsitettä sekä journalismia laajemmin. Keskeisin tutkimustulos tutkielmassani on, että Neuvostoliiton erityisasema suomalaisessa urheilujournalismissa oli merkittävä. Neuvostoliiton hajottua pienempien entisten neuvostotasavaltojen edustajiin, kuten Baltian maiden urheilijoihin, suhtauduttiin positiivisemmin kuin venäläisiin. Tämän lisäksi varsinkin jääkiekon asetelma muuttui urheilujournalistien käsittelyssä suhteessa Suomen itänaapuriin.

The traditional business models and the traditionally successful development methods that have been distinctive to the industrial era, do not satisfy the needs of modern IT companies. Due to the rapid nature of IT markets, the uncertainty of new innovations‟ success and the overwhelming competition with established companies, startups need to make quick decisions and eliminate wasted resources more effectively than ever before. There is a need for an empirical basis on which to build business models, as well as evaluate the presumptions regarding value and profit. Less than ten years ago, the Lean software development principles and practices became widely well-known in the academic circles. Those practices help startup entrepreneurs to validate their learning, test their assumptions and be more and more dynamical and flexible. What is special about today‟s software startups is that they are increasingly individual. There are quantitative research studies available regarding the details of Lean startups. Broad research with hundreds of companies presented in a few charts is informative, but a detailed study of fewer examples gives an insight to the way software entrepreneurs see Lean startup philosophy and how they describe it in their own words. This thesis focuses on Lean software startups‟ early phases, namely Customer Discovery (discovering a valuable solution to a real problem) and Customer Validation (being in a good market with a product which satisfies that market). The thesis first offers a sufficiently compact insight into the Lean software startup concept to a reader who is not previously familiar with the term. The Lean startup philosophy is then put into a real-life test, based on interviews with four Finnish Lean software startup entrepreneurs. The interviews reveal 1) whether the Lean startup philosophy is actually valuable for them, 2) how can the theory be practically implemented in real life and 3) does theoretical Lean startup knowledge compensate a lack of entrepreneurship experience. A reader gets familiar with the key elements and tools of Lean startups, as well as their mutual connections. The thesis explains why Lean startups waste less time and money than many other startups. The thesis, especially its research sections, aims at providing data and analysis simultaneously.

Raportin tarkoituksena on antaa yleiskuva paikkatiedon tilanteesta Kansalliskirjastossa sekä kartuttaa mahdolliset paikkatiedon tuottamisen ja hyödyntämisen uudistusskenaariot liittyen laajempaan kuvailun muutokseen. Mahdollisten uudistusten arviointia varten dokumentissa esitellään keskeiset hyödynnettävissä olevat suomalaiset ja kansainväliset paikkatietoresurssit sekä haasteet ja hyödyt liittyen niiden laajempaan hyödyntämiseen. Selvitys on laadittu Kansalliskirjaston Finto-projektin ja Fennica-yksikön asiantuntijoiden yhteistyönä.

E-Commerce is not a new phenomenon, but strictly speaking, it has breakthrough during the past 15 years. E-commerce is adopted differently across European countries, even though almost all of them are considered to be advanced industrialized nations. These notions are made at the same time as E-Commerce markets grow year by year. Countries seem to evolve at a different pace. At the same time, customers get more and more experienced with the Internet and perceive online marketplace more critically. Also, companies have their important role in the development of E-Commerce. E-Commerce research has been conducted on three levels of analysis: individual, company, and country. In this thesis, the primary focus is on the differences between B2C retail E-Commerce in Finland, Germany, and the United Kingdom. The research is conducted with an exploratory method by collecting data from secondary sources. The research suggests that there are no significant differences between delivery methods in Finland, Germany, and the United Kingdom. When it comes to payment methods, the results suggests that there is a statistically significant difference between Germany and United Kingdom.
