Akateemiset urapolut. Humanistisen, yhteiskuntatieteellisen ja kasvatustieteellisen alan generalistien urapolkujen alkuvaiheet 1980- ja 1990-luvuilla

Academic Career Paths. The early career phases of generalists in the fields of humanities, social science and education in the 1980’s and 1990’s This doctoral thesis analyses how generalist graduates of master’s degree have attached to the labour market in two different time periods, and how their career paths in the first eight years following graduation have shaped up. The thesis also analyses the channels of employment through which the generalists have got employed in their early career path. By generalists I am referring to graduates of studies in academic fields which have not qualified the person in a specific profession but rather offered a more general readiness for working life. I address two groups of generalist master’s degree graduates of The University of Turku; one including graduates of the year 1985 and the other consisting of graduates of 1995. All subjects have graduated in the field of humanities, social studies or education. 71 respondents from the group of 1985 and 80 respondents from the group of 1995 answered a survey, which provided the data for the thesis. I interpret the data through the theoretical approaches of changing working life, model of normal employment, transitional labour markets, linear life path, overlapping life courses, hidden labour market and social capital. The conclusion of the thesis is that societal era is connected with employment and career paths of academic generalists. Between the two groups there were differences especially in attachment to labor market, in forms of employment (permanent full-time job vs. temporary job) and in employment channels. Compared to the situation the 1985 group had been in after their graduation, the 1995 group - after getting their degree - became more often unemployed and/or employed in duties below their level of education. Their mobility was also greater and their contracts were often temporary, whereas the graduates of 1985 had been employed in more permanent positions. I demonstrate that the career paths of generalists can be categorized in five career types: steady state, transitory, linear, unsteady and diverging career. Graduates of 1985 have been treading on more stable paths than the latter group. The channels of employment they used were roughly equally divided between formal (e.g. newspaper advertisement and employment office) and informal (e.g. personal contacts and unprompted search for work) channels, whereas amongst the 1995 group employment happened through more varied channels and mostly through informal channels. Regardless of their year of graduation the generalists’ careers had begun to evolve already while they were still in the university and had started working at the same time. The thesis displays how the model of normal employment has weakened and career paths have become unsteady as a consequence of temporary positions. What is also evident in employment when turning from the 1980’s towards the succeeding decade is the rise of significance of the hidden labour market and social capital.

Injetor multicanal com válvulas de estrangulamento para análise em fluxo

An important component for the automation of flow injection analysis (FIA) systems is the sample injection valve. A simple and inexpensive commutator with 16 pinch valves (8 normally open and 8 closed) was developed and configured as a multichannel injection valve. It is activated by a single solenoid of 3 Kgf, powered by a pulsed driver circuit, controlled by a microcomputer or a switch. FIA with spectrophometric detection of potassium dichromate solution was used for the evaluation of the new injection valve and its comparison with other valves, for sample loops of 50, 100, 200, 300 and 500 muL. The repeatability was favorable (RSD 1.0% for 15 injections at each loop volume) compared to a manual injector, an electropneumatic injector and an injector configured with three mini solenoid valves (RSD 1.1, 1.3 and 1.0%, respectively, for15 injections at each loop volume).

PK-YRITYKSET INNOVAATTOREINA : Satunnaisista parannuksista kohti innovaatioiden virtaa. Yhteenveto tutkimusraportista, 3/2009

Tämän tutkimuksen tarkoituksena oli selvittää, minkälaisia innovaatioita eri toimialojen pienissä yrityksissä on kehitetty ja minkälaisia kyvykkyyksiä se on edellyttänyt. Lisäksi tavoitteena oli selvittää, kuinka suotuisana ympäristönä yritykset kokivat oman alueensa ja miten alueiden kehittämistyö on vaikuttanut yritysten kykyyn kilpailla. Teoreettiset oletukset perustuvat aikaisempiin tutkimuksiin innovaatiojohtamisen, yrittäjyyden ja pk-yritysten liiketoiminnan kehittämisen alueilta. Empiirinen aineisto on kerätty sähköpostikyselyllä tuottaen 733 kriteerit täyttävää vastausta. Kyselytutkimusta edelsi neljän alueen tapaustutkimus, jonka aikana luotiin teoreettinen rakennelma pienten yritysten innovaatiokyvykkyyden arvioimiseksi. Tämän tutkimuksen aineisto ei tue yleistä väitettä, jonka mukaan innovaatiotoiminta olisi harvinaisempaa tai vähäisempää kooltaan pienemmissä yrityksissä. Kokoa enemmän näyttäisi vaikuttavan innovaatiotoiminnan luonne ja siihen kytkeytyvä kyvykkyys. Yritysten innovaatio-toiminnan luonteen ja laajuuden perusteella tuloksista nousee neljä erilaista innovaattoriprofiilia: satunnainen parantaja, jatkuva parantaja, radikaali uudistaja ja monipuolinen kehittäjä. Innovaatiokyvykkyyttä tutkittiin seitsemän eri osatekijän suhteen. Eri profiilit omaavien yritysten kyvykkyyden tasot erosivat toisistaan merkittävästi. Tulokset vahvistavat käsityksiä siitä, että yksittäisen kyvykkyystekijän sijaan kyvykkyyskombinaatio vaikuttaa enemmän innovatiotoiminnan monipuolisuuteen. Innovaatiotoiminnan lisääntyessä ja monipuolistuessa, yritysten kyvykkyys-vaatimukset kasvavat kaikkien osatekijöiden suhteen. Yritykset ovat tiedostaneet innovaatio-kyvykkyyden kehittämisen tarpeet. Kyvykkyys on ajuri, jonka kyydissä pienet ja suuret innovaatiot syntyvät. Tämä tutkimus suosittelee, että innovaatiokyvykkyyden kehittäminen nostetaan näkyväm-mäksi tavoitteeksi. Pienissä yrityksissä luontevin tapa vahvistaa kyvykkyyksiä on integroida se yrityksen kehittämistoimintaan johtaen itse itseään ruokkivaksi prosessiksi. Haasteelliset kehittämis-tavoitteet edellyttävät monipuolista kyvykkyyksien vahvistamista ja vahvistuneet kyvykkyydet mahdollistavat entistä haastavampien kehittämistavoitteiden asettamisen. Parhaimmillaan tämä prosessi johtaa pienelle yritykselle soveltuvaan onnistumisen spiraaliin, joka samanaikaisesti kiihdyttää sekä kyvykkyyksien että innovaatioiden kehittämistä - tuotoksena jatkuva ja monipuolinen innovaatioiden virta. Tulokset vahvistavat ensimmäisessa vaiheessa toteutetun tapaustutkimuksen havaintoja siitä, että alueiden kehittämistyöstä hyötyvät yritykset, joiden kyvykkyystekijät ovat entuudestaan korkeaa tasoa. Pitkälle tuotteistetut julkiset palvelut soveltuvat parhaiten suuremmille yrityksille, joissa kehittämistoiminta on projektoitu ja kehittämistyö tehdään erillisten resurssien turvin. Sitä vastoin, valtaosassa pieniä yrityksiä kehittämistyö tapahtuu tavanomaisen liiketoiminnan ohessa ja samoilla resursseilla. Alueet tarjoavat varsin runsaasti luonteeltaan epäjatkuvia palveluja kohdistuen yksittäisten kyvykkyystekijöiden parantamiseen tai prosessin yksittäiseen vaiheeseen, usein innovaatioprosessin alkupäähän radikaalin innovaation kehittämiseksi. Tämän kyselyn tulokset suosittelevat myös toista reittiä: vahvistetaan ensin yritysten innovaatiokyvykkyyttä jatkuvaan pieniä askelia ottavaan innovaatiotoimintaan, josta matka jatkuu radikaalien uudistusten kautta moni-puoliseksi kehittämiseksi.

When culture does (not) matter: role models and self-efficacy as drivers of entrepreneurial behavior

The correlation between facets of national culture and startup activities has received confirmation in empirical research while many mechanisms behind the correlation remain unclear. We study the interplay between the individualism-collectivism orientation of national culture, the incidence of entrepreneurial role models and selfefficacy understood as the perception of possessing relevant skills and knowledge to become a successful entrepreneur. We find that exposure to entrepreneurial role models offsets self-efficacy as a driver of entrepreneurial intentions. The effect is magnified by the individualistic character of the national culture. Key words: entrepreneurial intentions, role models, self-efficacy, individualism, multilevel regressions

Invasive species and habitat degradation in Iberian streams: an analysis of their role in freshwater fish diversity loss

Mediterranean endemic freshwater fish are among the most threatened biota in the world. Distinguishing the role of different extinction drivers and their potential interactions is crucial for achieving conservation goals. While some authors argue that invasive species are a main driver of native species declines, others see their proliferation as a co-occurring process to biodiversity loss driven by habitat degradation. It is difficult to discern between the two potential causes given that few invaded ecosystems are free from habitat degradation, and that both factors may interact in different ways. Here we analyze the relative importance of habitat degradation and invasive species in the decline of native fish assemblages in the Guadiana River basin (southwestern Iberian Peninsula) using an information theoretic approach to evaluate interaction pathways between invasive species and habitat degradation (structural equation modeling, SEM). We also tested the possible changes in the functional relationships between invasive and native species, measured as the per capita effect of invasive species, using ANCOVA. We found that the abundance of invasive species was the best single predictor of natives’ decline and had the highest Akaike weight among the set of predictor variables examined. Habitat degradation neither played an active role nor influenced the per capita effect of invasive species on natives. Our analyses indicated that downstream reaches and areas close to reservoirs had the most invaded fish assemblages, independently of their habitat degradation status. The proliferation of invasive species poses a strong threat to the persistence of native assemblages in highly fluctuating environments. Therefore, conservation efforts to reduce native freshwater fish diversity loss in Mediterranean rivers should focus on mitigating the effect of invasive species and preventing future invasions

A reação de ciclização de prins: uma estratégia eficiente para síntese estereosseletiva de anéis tetraidropirânicos substituídos

The Prins cyclization reaction has significantly advanced in the last years as demonstrated by a number of applications described in the literature. The objective of this report is to introduce this powerful synthetic methodology to the undergraduate and graduated student, since it is rarely presented in an organic synthesis formal course. This reaction is, in some cases, the methodology of choice for the preparation of natural products or drugs that present the tetrahydropyrane moiety in their structures. In this report we show some aspects of this reaction, including mechanism, scope and limitations.

Menestyksekkäät yliopistopelin pelaajat? Tutkimus nopeasti ja nuorena valmistumisesta

Succestul players of the university game? A study about the short duration of master’s degree studies and graduating at a young age The duration of studies has long been a topic of conversation. It was first mentioned in 1883, but the discussion has been quite active and topical for the last fifty years. During that time, there have been numerous committees, working groups for the Ministry of Education, and revisions to the structure of the master’s degree program. All of these have focused on lowering the duration of studies as well as the age at which students graduate. These two factors have been regarded as indicators of efficiency. Achieving these goals is seen to promote the successful transition from studies to work. In addition, the greater time that people spend working is thought to help with the fiscal burden of an aging population. The reasons for prolonged study seem to be: students working during the course of their studies; the actual workload of the studies, which sometimes does not correlate with the calculated workload; problems with the students’ course selections and with their financial support from the government; issues in teaching; and problems with university funding. This study focuses on students’ study experiences, their progress, and the university itself. Of particular interest was the students’ use of different resources—cultural, social, and economical capital. Participants in the study had graduated from the University of Turku between the years of 1999 and 2001 and were divided into two groups: prompt graduates, those who graduated among the fastest 18th percent in their faculty; and those who graduated at a slower pace. A survey (N=499) and interviews (N=69) were among the methods used, along with a compilation of statistics on the students’ duration of studies, the number of modules studied, and marks obtained. Bourdieu’s theory about fields and the games people play in those fields formed the theoretical background of this study. The university was seen to form a playing field with historically and politically changeable rules. The students playing in this field were considered to possess different economical, social, and cultural resources, which they use more or less successfully. Some of the strategies used by students result in gra¬duating at a young age and/or a short duration of study; some do not. This study divided the age of graduation and the duration of study into separate games. This allowed the study to determine the relationship between these two factors and to examine their similarities and differences. The study also focused on the idea of success. Short duration of studies and a young graduation age can be considered, be some, an indication of success in navigating the university field. This study aimed to see if this concept held true or whether these seeming indicators of success have negative side effects. The main result of this study is that, even though the games of duration and age have similarities, they are sufficiently diverse to be considered separate games, which need different resources. To graduate with a short duration of studies, it is important for a student to successfully view and navigate the university field, tailoring one’s studies and extracurricular activities to suit the individual. In the game of youth, the background of the student seemed to be of greater importance. The youngest graduates had spent more time with their parents, who also had higher educational qualifications. They also had higher achievement in their previous studies. This seems to indicate that their background allowed them to assimilate a better understanding of the school and university fields and that playing the university game was natural for them. As for the aspect of success, it seems that there are many ways to define the term. Youth on graduation and short duration of studies can be seen as two indicators of success. Both revealed negative and positive outcomes, even though short duration of studies seemed more often to be connected with positive outcomes. However, it seems that the best indicator for success is the way in which students organize study into their lives to support and suit their needs and abilities to realize a meaningful life and a successful entry into the field of work.

Cytoplasmic accumulation of NCoR in malignant melanoma: Consequences of altered gene repression and prognostic significance

Invasive malignant melanoma (MM) is an aggressive tumor with no curative therapy available in advanced stages. Nuclear corepressor (NCoR) is an essential regulator of gene transcription, and its function has been found deregulated in different types of cancer. In colorectal cancer cells, loss of nuclear NCoR is induced by Inhibitor of kappa B kinase (IKK) through the phosphorylation of specific serine residues. We here investigate whether NCoR function impacts in MM, which might have important diagnostic and prognostic significance. By IHC, we here determined the subcellular distribution of NCoR in a cohort of 63 primary invasive MM samples, and analyzed its possible correlation with specific clinical parameters. We therefore used a microarray-based strategy to determine global gene expression differences in samples with similar tumor stage, which differ in the presence of cytoplasmic or nuclear NCoR. We found that loss of nuclear NCoR results in upregulation of a specific cancer-related genetic signature, and is significantly associated with MM progression. Inhibition of IKK activity in melanoma cells reverts NCoR nuclear distribution and specific NCoR-regulated gene transcription. Analysis of public database demonstrated that inactivating NCoR mutations are highly prevalent in MM, showing features of driver oncogene.

Expectations and Experiences of International Students in Information Technology Department

Education in Finland plays a significant role. International students are becoming an essential part of Finnish Educational system. The study was meant to examine their expectations and experiences in a Finnish University. As a case, Lappeenranta University of Technology (LUT) was chosen and, in particular, Information Technology (IT) Department. The main objectives of the study were to examine students’ satisfaction of their study experiences, their evaluation of the teaching quality of courses and last but not least the cultural impact on those. Data for the study were mainly collected with the help of three Internet surveys from a sample of 50 students – currently studying at LUT or already graduated. Response rate from questionnaire to questionnaire varied, however, still close to average and was considered as good and relevant enough. The study was initially meant as qualitative, however, a number of quantitative data analysis methods were used as well. Most of students’ expectations appear to become true, majority of students are satisfied with their experiences. Results show that teaching quality in LUT is evaluated as ‘good’. Nevertheless, students prefer particular courses to the other ones. In conclusion, it can be said that culture does affect students’ expectations, experiences, perception of the world, however, cultural differences do not cause any serious problems.

Strategic Development of Electricity Distribution Networks – Concept and Methods

Strategic development of distribution networks plays a key role in the asset management in electricity distribution companies. Owing to the capital-intensive nature of the field and longspan operations of companies, the significance of a strategy is emphasised. A well-devised strategy combines awareness of challenges posed by the operating environment and the future targets of the distribution company. Economic regulation, ageing infrastructure, scarcity of resources and tightening supply requirements with challenges created by the climate change put a pressure on the strategy work. On the other hand, technology development related to network automation and underground cabling assists in answering these challenges. This dissertation aims at developing process knowledge and establishing a methodological framework by which key issues related to network development can be addressed. Moreover, the work develops tools by which the effects of changes in the operating environment on the distribution business can be analysed in the strategy work. To this end, the work discusses certain characteristics of the distribution business and describes the strategy process at a principle level. Further, the work defines the subtasks in the strategy process and presents the key elements in the strategy work and long-term network planning. The work delineates the factors having either a direct or indirect effect on strategic planning and development needs in the networks; in particular, outage costs constitute an important part of the economic regulation of the distribution business, reliability being thus a key driver in network planning. The dissertation describes the methodology and tools applied to cost and reliability analyses in the strategy work. The work focuses on determination of the techno-economic feasibility of different network development technologies; these feasibility surveys are linked to the economic regulation model of the distribution business, in particular from the viewpoint of reliability of electricity supply and allowed return. The work introduces the asset management system developed for research purposes and to support the strategy work, the calculation elements of the system and initial data used in the network analysis. The key elements of this asset management system are utilised in the dissertation. Finally, the study addresses the stages of strategic decision-making and compilation of investment strategies. Further, the work illustrates implementation of strategic planning in an actual distribution company environment.
