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.

El papel de la memoria de trabajo en el cálculo mental un cuarto de siglo después de Hitch = The role of working memory in mental arithmetic a quarter of century after Hitch

Desde que Hitch (1978) publicó el primer estudio sobre el rol de la memoria de trabajo en el cálculo han idoaumentando las investigaciones en este campo. Muchos trabajos han estudiado un único subsistema, pero nuestroobjetivo es identificar qué subsistema de la memoria de trabajo (bucle fonológico, agenda viso-espacial o ejecutivocentral) está más implicado en el cálculo mental. Para ello hemos realizado un estudio correlacional en el quehemos administrado dos pruebas aritméticas y nueve pruebas de la “Bateria de Test de Memòria de Treball” dePickering, Baqués y Gathercole (1999) a una muestra de 94 niños españoles de 7-8 años. Nuestros resultadosindican que el bucle fonológico y sobretodo el ejecutivo central inciden de forma estadísticamente significativa enel rendimiento aritmético

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.

Explorando produtos naturais microbianos nas fronteiras da Química e da Biologia

The chemistry of natural products has been remarkably growing in the past few decades in Brazil. Aspects related to the isolation and identification of new natural products, as well as their biological activities, have been achieved in different laboratories working on this subject in the country. More recently, the introduction of new molecular biology tools has strongly influenced the research on natural products, mainly those produced by microorganisms, creating new possibilities to assess the chemical diversity of secondary metabolites. This paper describes some ideas on how the research on natural products can have a considerable input from molecular biology in the generation of chemical diversity. We also explore the role of microbial natural products in mediating interspecific interactions and their relevance to ecological studies. Examples of the generation of chemical diversity are highlighted by using genome mining, mutasynthesis, combinatorial biosynthesis, metagenomics, and synthetic biology, while some aspects of microbial ecology are also discussed. The idea to bring up this topic is linked to the remarkable development of molecular biology techniques to generate useful chemicals from different organisms. Here, we focus mainly on microorganisms, even though similar approaches have also been applied to the study of plants and other organisms. Investigations in the frontier of chemistry and biology require interactions between different areas, characterizing the interdisciplinarity of this research field. The necessity of a real integration of chemistry and biology is pivotal to finding correct answers to a number of biological phenomena. The use of molecular biology tools to generate chemical diversity and control biosynthetic pathways is largely explored in the production of important biologically active compounds. Finally, we briefly comment on the Brazilian organization of research in this area, the necessity of new strategies for the graduation programs, and the establishment of networks as a way of organization to overcome some of the problems faced in the area of natural products.

Kuka suunnittelee mainokset? Tutkimus mainosalan kulisseista,yhteistyökäytännöistä ja ristiriidoista. Mainonnan suunnittelijan näkökulma

Tutkimus kuvaa tapahtumia mainonnan suunnittelun kulissien takana ja niiden vaikutusta suunnittelutyöhön mainonnan suunnittelijan näkökulmasta. Lähestymistapa on systeemiteoreettinen: tutkimuksessa tarkastellaan sekä mainostoimiston suunnittelijoiden, projektijohtajien ja muiden mainonnan suunnitteluun osallistuvien keskinäistä vuorovaikutusta että mainostoimiston ja mainoksia tilaavan asiakkaan vuorovaikutuksen asettamia rajoja ja mahdollisuuksia. Keskeinen työväline on Kurt Lewinin kentän käsite. Tutkimuksessa se konkretisoituu esitystavaksi mainonnan suunnittelun olennaisista piirteistä, jotka ovat toisistaan riippuvaisia. Tutkimusta pohjustaa ajatus mainonnan suunnittelun perusrakenteesta, joka on riippumaton taloudellisista, yhteiskunnallisista tai mainostoimialan liiketoimintaympäristön muutoksista. Mainostoimistossa työtä tehdään usein ryhmässä. Ydinryhmä muodostuu kirjoittavan ja visuaalisen suunnittelijan työparista, mutta projektijohtaja on avainasemassa hoitaessaan yhteydenpitoa mainostoimiston asiakkaaseen. Tutkimustyötä viitoittivat kysymykset mainonnan suunnittelijoiden tehtävästä ja asemasta, työssä koetuista haasteista sekä osuudesta ja vastuusta lopullisissa töissä. Keskiössä ovat suunnittelutyötä raamittavat haasteet, jotka ohjaavat suunnittelijoiden kykyjä ja haluja toteuttaa luovuuttaan. Tutkimus ammentaa teoreettisia aineksia työnjaon ja tiimityön käsitteiden ohella vallan tilanteisuudesta ja suhteista sekä sosiaalisen pääoman ja luottamuksen moniaineksisuudesta. Tutkimuksen aineisto kerättiin syksyllä 2008 ja alkuvuodesta 2009 haastattelemalla suomalaisten mainostoimistojen suunnittelijoita. Haastatteluaineisto koostuu kymmenestä ryhmähaastattelusta, johon kuhunkin osallistui 3–4 suunnittelijaa. Muu aineisto sisältää toimialan tilastoja ja julkaisuja sekä yksityisiä sähköpostikirjeenvaihtoja ja keskusteluja mainosammattilaisten kanssa. Haastatteluaineisto analysoitiin Milesin ja Hubermannin aineistolähtöisen sisällönanalyysin avulla ja sitä täydennettiin retorisella diskurssianalyysilla. Analyysin alkuvaiheessa koemetodina sovellettiin Straussin ja Corbinin aineistolähtöisen teorian (grounded theory) kolmivaiheista koodausta. Tutkimuksen tuloksena on malli mainonnan suunnittelun kentän jännitteistä, jotka johtavat toimimaan tietyllä tavalla. Mainonnan suunnittelijan tehtävinä näyttäytyvät vaikuttaminen, asiakkaan tarpeiden tunnistaminen ja tyydyttäminen sekä omakohtainen menestyminen. Suunnittelijan asema näyttää työssä koettujen haasteiden kautta häilyvän asiantuntijuuden ja alihankkijuuden välimaastossa. Työn henkilökohtaisina haasteina piirtyvät tarmokkuuden ja jatkuvan oivaltamisen vaateet. Ulkoisina tekijöinä talouden, teknologian ja sen myötä median murros sekä haastaa että kehittää: alituiseen kiireeseen näytetään verhoavan pulmia, joiden todellinen alkuperä paikantuu muualle. Keskeiset ristiriidat ja toiminnan edellytykset ilmenevät juuri yhteistyössä: mainostoimiston sisäinen yhteistyö ja asiakkaan antama palaute ovat merkittäviä tekijöitä luottamuksen taustalla. Siten avoin ja vastavuoroinen kommunikaatio piirtyy olennaiseksi asetettujen tavoitteiden saavuttamisessa ja asiakkaan menestymisessä. Mainonnan suunnittelussa tärkeäksi kysymykseksi nousevat portinvartijoiden roolit. Mainostoimiston sisäisessä työskentelyssä projektijohtajat hallinnoivat suunnitteluresursseja, välittävät tietoa asiak kaalta suunnittelijalle ja päinvastoin sekä tekevät tärkeimmät päätökset. Asiakkaan puolella mainoksia tilaava asiakashenkilö hallinnoi valjastamiaan resursseja, mutta varsinainen päätöksenteko tapahtuu tämän esimiehen toimesta. Tulosten valossa on perusteltua uskoa, että mainonnan suunnittelijat kokevat oman työnsä arvon alentuneen ja päätösvaltansa vähentyneen. Mainostoimialan murroksen kannalta tutkimus tuo esiin uudenlaisen tiimityön ymmärtämisen ja korostaa yksilöiden vahvuuksien tunnistamisen merkitystä. Kiristyvässä taloudessa se suuntaa huomion sekä mainostoimistojen että niiden asiakasyritysten sisäisten ja ulkoisten resurssien tehokkaaseen ja tuottavaan hyödyntämiseen ja organisoimiseen. Sosiologisesti tutkimus tarjoaa yhdenlaisen näkökulman ryhmätyön ulottuvuuksiin ja työelämän yhteistyöhaasteiden pohtimiseen. Siten tutkimuksen tuloksilla voi nähdä arvoa myös muiden kuin mainosalan yhteistyökäytäntöjentarkasteluun.

Mobile system for pump working point estimation

In the current economy situation companies try to reduce their expenses. One of the solutions is to improve the energy efficiency of the processes. It is known that the energy consumption of pumping applications range from 20 up to 50% of the energy usage in the certain industrial plants operations. Some studies have shown that 30% to 50% of energy consumed by pump systems could be saved by changing the pump or the flow control method. The aim of this thesis is to create a mobile measurement system that can calculate a working point position of a pump drive. This information can be used to determine the efficiency of the pump drive operation and to develop a solution to bring pump’s efficiency to a maximum possible value. This can allow a great reduction in the pump drive’s life cycle cost. In the first part of the thesis, a brief introduction in the details of pump drive operation is given. Methods that can be used in the project are presented. Later, the review of available platforms for the project implementation is given. In the second part of the thesis, components of the project are presented. Detailed description for each created component is given. Finally, results of laboratory tests are presented. Acquired results are compared and analyzed. In addition, the operation of created system is analyzed and suggestions for the future development are given.

Working Capital Management: a Bibliometric Study

This thesis is a study of articles published in scientific journals about working capital management using bibliometric methods. The study was restricted to articles published in 1990–2010 that deal with the whole working capital management topic not a single sub-area of it. Working capital is defined as current assets minus current liabilities; sometimes also a definition of inventory plus accounts receivable minus accounts payable is used. The data was retrieved from the databases ISI Web of Science and Sciverse Scopus. Articles about working capital management were found 23. Content analysis, statistical analysis and citation analysis was performed to the articles. The most cited articles found in citation analysis were also analyzed by nearly same methods. This study found that scientific research of working capital management seems not to be concentrated to specific persons, organizations or journals. The originality and novelty in many articles is low. Many articles studied relation between working capital management and profitability in firms or working capital management practices of firms using statistical analyses. Data in articles was firms of all sizes, except in developing economies only big firms were used. Interesting areas for future research could be surveys made about working capital management practices in firms, finding of best practices, tools for working capital management, inventing or improving alternative views to working capital management like process-oriented view and firm or industry specific studies.

Working capital management in the value chain of automotive industry

The objective of this Master’s thesis is to examine working capital management in the automotive industry in years 2006-2008. The study is conducted by the analysis of financial statements. The sample consists of 65 companies that represent different stages in the value chain of automotive industry beginning from raw material suppliers and ending to car dealers. Working capital management is studied by the cash conversion cycle (CCC). The results show that the average CCC of the value chain is 67 days. Car manufacturers had the longest CCC, 106 days, whereas the CCC of oil companies was the shortest, 22 days. The findings suggest that the cycle time of working capital usually follows the cycle time of inventories, since the changes in cycle times of accounts receivable and payable compensate each other. Improvements in working capital management could be achieved by sharing more accurate information in the chain for example about inventory levels and order points of customer. It could also be discussed within the automotive industry, if the long credit periods, which tie up working capital, are really needed. New technologies enable faster payments, which would reduce the cash conversion cycles, improve the profitability of companies, and increase the competitiveness of the value chain. Working capital should not be reduced at the expense of value chain partners, because nowadays the competition is rather between the value chains than between the companies. Similar research design is applied earlier to study working capital management in the value chain of pulp and paper industry. Even if the industries and the structures of the chains differ from each other, results were surprisingly similar. In future research, working capital management in other industries’ value chains could still be studied and compared to previous studies. ICT industry, for example, could be an interesting object.

Evaluation of alternative containers to determining the working width of fertilizer spreaders

Farmers have difficult of determining the evenness of transverse distribution and the working width, due the tests with this aim require equipments and complex methodologies. So, this study evaluates some alternative containers with the aim to allow a more accessible adjustment of the full width of the solid fertilizer spreaders. Four different containers were tested: i) standard container constructed in accordance with ISO 5690/1; ii) container of polyethylene (plastic trays) with screen shading to prevent the ricochet of material; iii) containers composed by boxes of long-life milk, and iv) containers composed by flowerpots (number 3.5). Also, three different spreaders were used for the tests. Alternative containers showed greater retention of particles than the standardized containers. The full width of work obtained for the coefficients of variation of 12.5; 15; 17.5 and 20%, ranged due the containers in the different pathways. The flowerpots of polyethylene showed similar results to the standardized containers. The heights of the containers were more important for its efficiency than its area of collection.

Effect of working pressure at different spray nozzles on drift quantification in wind tunnel

Each year, there is an increase in pesticide consumption and in its importance of use in the large-scale agricultural production, being fundamental the knowledge of application technology to the activity success. The objective of the present study was to evaluate the influence of working pressure on the drift generated by different spray nozzles, assessed in wind tunnel. The treatments were composed of two spray nozzles AXI 110015 and AXI 11002 with pressure levels of 276 and 414 kPa. The spray solution was composed by water and NaCl at 10%. The applications were conducted at wind speed of 2.0 m s-1, being the drift collected at 5.0; 10.0 and 15.0 m away from the spray boom and at heights of 0.2; 0.4; 0.6; 0.8 e 1.0 m from the tunnel floor. To both spray nozzles, the greatest drift was collected at the smallest distance to the spray-boom and at the lowest height. The AXI 11002 nozzle gave a smaller drift relative to the AXI 110015 nozzle for the two tested pressures and for all the collection points. Regardless of the nozzle, a rise in the working pressure increases the spray drift percentage at all distances in the wind tunnel.

Working capital management in the small and medium-sized enterprises Case: Project-based business environment in Flowrox Oy

This Master´s thesis illustrates how growing a business ties up the company´s working capital and what the cost of committed capital. In order to manage a company´s working capital in rapid business growth phase, the thesis suggests that by monitoring and managing the operating and cash conversion cycles of customers´ projects, a company can find ways to secure the required amount of capital. The research method of this thesis was based on literature reviews and case study research. The theoretical review presents the concepts of working capital and provides the background for understanding how to improve working capital management. The company in subject is a global small and medium-sized enterprise that manufactures pumps and valves for demanding process conditions. The company is expanding, which creates lots of challenges. This thesis concentrates to the company´s working capital management and its efficiency through the supply chain and value chain perspective. The main elements of working capital management are inventory management, accounts receivable management and accounts payable management. Prepayments also play a significant role, particularly in project-based businesses. Developing companies´ working capital management requires knowledge from different kind of key operations´ in the company, like purchasing, production, sales, logistics and financing. The perspective to develop and describe working capital management is an operational. After literature reviews the thesis present pilot projects that formed the basis of a model to monitor working capital in the case company. Based on analysis and pilot projects, the thesis introduces a rough model for monitoring capital commitments in short time period. With the model the company can more efficiently monitor and manage their customer projects.
