Ajoneuvokatsastuksen valvontamalli

Tutkimuksessa kehitettiin ajoneuvokatsastuksen suorituskykymittari sekä suorituskyvyn johtamiseen perustuva ajoneuvokatsastuksen valvontamalli. Suorituskykymittarin avulla voidaan mitata ajoneuvokatsastuksen suorituskykyä, seurata suorituskyvyn kehitystä, suunnitella ja päättää mitä pitäisi parantaa sekä seurata tehtyjen toimenpiteiden vaikutuksia eli johtaa toimintaa. Tutkimuksessa kehitetty suorituskykymittari perustuu Liikenteen turvallisuusviraston ylläpitämään ajoneuvoliikennerekisteriin tallennettujen katsastustietojen analysointiin sekä tilastollisten prosessin ohjausmenetelmien (SPC) hyödyntämiseen. Tutkimuksessa kehitetyssä ajoneuvokatsastuksen valvontamallissa Liikenteen turvallisuusviraston valvontatoimintoja sekä katsastusyritysten omaa laadunhallintaa johdetaan suorituskykymittarin avulla. Tutkimuksessa kehitetyn suorituskykymittarin ja valvontamallin avulla Liikenteen turvallisuusvirastolla ja katsastusyrityksillä on aiempaa paremmat edellytykset valvoa ja johtaa ajoneuvokatsastuksen suorituskykyä katsastustoiminnalle asetettujen tavoitteiden kannalta vaikuttavasti ja oikein. Tutkimus toteutettiin konstruktiivista tutkimusotetta käyttäen ja tutkimuksessa kehitetty ajoneuvokatsastuksen valvontamalli implementoitiin osaksi kansallista lainsäädäntöä sekä Liikenteen turvallisuusviraston ja katsastusyritysten johtamistoimintoja.

Yhteiskuntavastuullinen toimittajavalinta

Yritysten yhteiskuntavastuu on viime vuosina noussut merkittäväksi osaksi yritysten jokapäiväistä toimintaa. Yhteiskuntavastuun aseman kehittymiseen yritysten strategiseksi valinnaksi on edesauttanut internetin sidosryhmille tarjoama lähes rajaton informaatio, joka on pakottanut yritykset muuttamaan toimintatapojaan kestävämpään suuntaan. Nykyinen asetelma on myös pakottanut yritykset miettimään uudestaan mitä he yhteiskuntavastuullaan haluavat sidosryhmilleen viestiä, ja miten he sen tekevät. Vastauksena tähän yritykset ovat kehittäneet voimakkaasti yhteiskuntavastuuraportointikäytäntöjään viime vuosien aikana, mikä näkyy muun muassa erialaisten raportointiohjeistusten hyödyntämisen yleistymisenä yhteiskuntavastuuraportoinnin apuvälineenä. Tämän tutkielman tarkoituksena on selvittää mitä yhteiskuntavastuu on, ja millaisia keinoja yrityksillä on integroida yhteiskuntavastuullinen toiminta osaksi hankintatoimeen kuuluvaa toimittajavalintaa. Työn empiriaosuus on toteutettu laadullisena tutkimuksena vertailemalla kahden suomalaisen eri toimialoilla toimivan yrityksen yhteiskuntavastuuraportteja, ja sen tavoitteena on löytää teemoja ja työkaluja, joiden avulla yritykset implementoivat yhteiskuntavastuuta toimittajavalinnassaan. Tutkimuksen yksi merkittävimmistä löydöistä oli yritysten tarve nostaa sekä yhteiskuntavastuu että toimittajavalinta strategisiksi toiminnoiksi, mitä tukee molempien empiriaosuudessa käytettyjen yritysten yhteiskuntavastuuraporteista löytynyt maininta toimitusketjujen sekä toimittajavalinnan suuresta merkityksestä yritysten yhteiskuntavastuun toteuttamisen välineenä.

Tratamiento de hipertrigliceridemia con terapia botánica y fibratos

Debido al aumento que ha venido presentado la práctica de la medicina tradicional en los últimos años, la OMS presenta en el 2003 la estrategia sobre la práctica de la medicina tradicional a los países en los cuales este tipo de medicina es más frecuente año tras año. Las plantas se han ido clasificando y han recibido denominación botánica, también han sido químicamente analizadas para poder distinguir sus componentes y diferenciar sus principios activos. Los Fibratos son fármacos utilizados ampliamente en la práctica clínica para la regulación de los lípidos y reducción del riesgo cardiovascular. A ellos se les atribuye una disminución promedio en los niveles de triglicéridos del 36%.

Managing non-standard international experience: evidence from a Finnish company

Purpose – This paper extends the increasing debates about the role of international experience through mechanisms other than standard expatriation packages, in particular through the use of short-term assignments. It explores the different forms of short-term assignments (project work, commuter assignments, virtual international working and development assignments) and the different sets of positive and negative implications these can have for the company and the individuals concerned. The integration-differentiation debate is reflected here as elsewhere in IHRM, with the company moving towards greater centralization and control of its use of these assignments. Design/methodology/approach – Since the research is exploratory, we adopted a qualitative approach to get a more in-depth understanding on the realities the corporations and the assignees are facing. The study was implemented through a single case study setting in which the data were collected by interviewing (n=20) line managers, human resource management (HRM) staff and assignees themselves. In addition corporate documentation and other materials were reviewed. Findings – The present case study provides evidence about the characteristics of short-term assignments as well as the on the management of such assignments. The paper identifies various benefits and challenges involved in the use of short-term assignments both from the perspectives of the company and assignees. Furthermore, the findings support the view that a recent increase in the popularity of short-term assignments has not been matched by the development of HRM policies for such assignments. Research limitations/implications – As a single case study, limitations in the generalizability of the findings should be kept in mind. More large-scale research evidence is needed around different forms of international assignments beyond standard expatriation in order to fully capture the realities faced by international HRM specialists Practical implications – The paper identifies many challenges but also benefits of using short-term assignments. The paper reports in-depth findings on HR development needs that organizations face when expanding the use of such assignments. Social implications – The paper identifies many challenges but also benefits of using short-term assignments. The paper reports in-depth findings on HR development needs that organizations face when expanding the use of such assignments. Originality/value – Empirical research on short-term assignments is still very limited. In that way the paper provides much needed in-depth evidence on why such assignments are used, what challenges are involved in the use of such assignments and what kinds of HR-development needs are involved.

Exploring expatriate outcomes

This editorial article introduces this special issue of the International Journal of Human Resource Management devoted to the outcomes of expatriate assignments. We set the topic in context. We start by summarizing the traditional view on expatriate outcomes. We then argue that recent developments in the field suggest the need to build a more sophisticated and complex analysis on the topic that incorporates different perspectives (e.g. the organization, the expatriate, their co-workers and their families) and additional types of international experiences and organizations. We then present some difficulties in developing such an analysis. Specifically, using a new typology of complementary relationships among outcomes (i.e. temporal, among-group and among-outcome consistencies), we point out some complications to achieve those relationships. We conclude by introducing the papers in the special edition that all in some way aim to contribute to our understanding of expatriate outcomes.

The career competencies of self-initiated and assigned expatriates: assessing the development of career capital over time

Building on a modern careers approach, we assess the effects of working abroad on individuals’ career capital. Given the dearth of longitudinal studies, we return to a sample of economics graduates in Finland eight years later. We measure changes in three dimensions of career capital; ‘knowing how’, ‘knowing whom’, ‘knowing why’ and find that company assigned expatriates learn more than self-initiated expatriates. All three career capital areas benefit from international experience and all are increasingly valued over time. Based on our findings we conclude that a dynamic notion of career capital acquisition and use is needed. Managerial implications include the need for a wider view of talent management for international businesses.

Meanings of overweight In societal discourses overweight is defined as a growing individual and a social problem leading to sickness and disability, mental distress, increased use of health care and reduced economic productivity. A strong normative pressure is directed at the overweight but relatively few succeed in reducing their weight. Therefore, the overweight need to manage a double stigma; the overweight body per se and their inability to conform to norms about bodyweight. This article investigates how individuals present their overweight to their social environment. Empirical data was collected as part of an evaluation study of a keep-fit project directed at home-care staff. Qualitative interviews were conducted with 49 participants and 30 of them had either tried or were trying to reduce their weight. The analysis shows that the informants presented a divided self consisting of a biological body, with its own drives, and a mind that is aware of the body and its social meanings. They portrayed their lives as a battle between these two sides. Their presentations of the divided self can be analysed as a defence of their social selves. The overweight can account for the kilos by blaming the biological drives, which leaves the core of themselves – their minds – unblemished. They can express an intention to loose weight and thereby conform to norms about bodyweight. When they fail to loose weight, the responsibility can be attributed to the unruly body.

Interactions of Electrons and Rydberg Atoms in Ultra-Cold Plasmas

This thesis discusses an experimental technique for investigating electron temperature control by Rydberg atoms in ultra-cold plasmas. The objective we set ourselves was twofold. Firstly, we sought to gain an insight into the processes whereby the creation of Rydberg atoms within the plasma lengthens the lifetime of the plasma. To this end, we created the plasma using a Littman dye laser and subsequently, at a variable time delay, we excited neutral atoms in the plasma to specific Rydberg states using a narrow bandwidth pulsed dye laser. Secondly, we employed radio-frequency (rf) electric fields to excite electron oscillations within the plasma in order to infer such information as plasma density and electron temperature. Although we found that the introduction of high angular momentum Rydberg states did lengthen the plasma lifetime we were not able to differentiate between the temperature moderation effect due to the Rydberg atoms cooling the plasma, and the binding effect due to an increased positive space charge within the plasma.

The village that vanished : The roots of erosion in a Tanzanian village

In the village'of Citing in the northern highlands of Tanzania, the factors: social stratification, land tenure, production strategies, investment patterns and the economic uncertainties of society are studied and their relationship to land degradation is examined. The main assumption of the study is that the causes of land degradation are so complex that a methodology that emphasises contextualisation has to be used. A methodological framework that considers inter-linkages between all these factors is developed and tested. The result of the test shows that contextualisation gives a more in-depth and complex explanation than conventional, positivist research. The study gives a detailed account of the relationship that various wealth groups have to land and land degradation in the village. It is found that all wealth groups are destructive to the land but in varying ways. The rich farmers are over-cultivating land marginal to agriculture, the middle peasants have too many cattle in the village while the poor peasants are so marginalised socially that they hardly influence land management. Those identified as having economic as well as social incentives to maintain soil fertility are the middle peasants, while the rich farmers are shown to be consciously soil-mining the former grazing areas.

Dissecting the role of the Golgi complex and lipid rafts in biosynthetic transport of cholesterol to the cell surface

In this study, we compared the transport of newly synthesized cholesterol with that of influenza virus hemagglutinin (HA) from the endoplasmic reticulum to the plasma membrane. The arrival of cholesterol on the cell surface was monitored by cyclodextrin removal, and HA transport was monitored by surface trypsinization and endoglycosidase H digestion. We found that disassembly of the Golgi complex by brefeldin A treatment resulted in partial inhibition of cholesterol transport while completely blocking HA transport. Further, microtubule depolymerization by nocodazole inhibited cholesterol and HA transport to a similar extent. When the partitioning of cholesterol into lipid rafts was analyzed, we found that newly synthesized cholesterol began to associate with low-density detergent-resistant membranes rapidly after synthesis, before it was detectable on the cell surface, and its raft association increased further upon chasing. When cholesterol transport was blocked by using 15°C incubation, the association of newly synthesized cholesterol with low-density detergent-insoluble membranes was decreased and cholesterol accumulated in a fraction with intermediate density. Our results provide evidence for the partial contribution of the Golgi complex to the transport of newly synthesized cholesterol to the cell surface and suggest that detergent-resistant membranes are involved in the process.

TGF-β3-induced Palatogenesis Requires Matrix Metalloproteinases

Cleft lip and palate syndromes are among the most common congenital malformations in humans. Mammalian palatogenesis is a complex process involving highly regulated interactions between epithelial and mesenchymal cells of the palate to permit correct positioning of the palatal shelves, the remodeling of the extracellular matrix (ECM), and subsequent fusion of the palatal shelves. Here we show that several matrix metalloproteinases (MMPs), including a cell membrane-associated MMP (MT1-MMP) and tissue inhibitor of metalloproteinase-2 (TIMP-2) were highly expressed by the medial edge epithelium (MEE). MMP-13 was expressed both in MEE and in adjacent mesenchyme, whereas gelatinase A (MMP-2) was expressed by mesenchymal cells neighboring the MEE. Transforming growth factor (TGF)-β3-deficient mice, which suffer from clefting of the secondary palate, showed complete absence of TIMP-2 in the midline and expressed significantly lower levels of MMP-13 and slightly reduced levels of MMP-2. In concordance with these findings, MMP-13 expression was strongly induced by TGF-β3 in palatal fibroblasts. Finally, palatal shelves from prefusion wild-type mouse embryos cultured in the presence of a synthetic inhibitor of MMPs or excess of TIMP-2 failed to fuse and MEE cells did not transdifferentiate, phenocopying the defect of the TGF-β3-deficient mice. Our observations indicate for the first time that the proteolytic degradation of the ECM by MMPs is a necessary step for palatal fusion.

Käyttöpääoman ennustaminen kysyntäennusteen avulla

Työn tavoite on selvittää erilaisia käyttöpääoman ennustusmalleja, jotka pohjautuvat kysyntäennusteeseen. Tavoitteena on esittää malleja niin pitkän kuin lyhyenkin aikavälin ennustamiseen. Pitkällä aikavälillä mallien on tarkoitus ennustaa yrityksissä sitoutuvan käyttöpääoman kokonaistarvetta, kun taas lyhyen aikavälin malleilla pureudutaan käyttöpääomaerien (lopputuotevarasto ja myyntisaamiset) ennustamiseen tuotekohtaisesti. Työssä pyritään myös vastaamaan, miksi käyttöpääomaa kannattaa ennustaa ja miten sen hallintaa voidaan tehostaa. Työ on toteutettu kirjallisuuskatsauksena, mitä on elävöitetty laskuesimerkein. Laskuesimerkkien tarkoitus on antaa lukijalle kuva käyttöpääoman ennustamisen todellisista mahdollisuuksista, jotta työ ei jäisi pelkäksi sanahelinäksi. Työssä esitetyt ennustusmallit on valittu matemaattisen yksinkertaisuutensa ehdolla, jotta niiden käyttäminen yritysmaailmassa olisi mahdollista. Käyttöpääomatarpeen ennustamisen suurimpana haasteena voidaan pitää kysyntäennusteen luotettavuutta. Vuositasolla käyttöpääomatarpeen keskimääräinen osuus suhteessa liikevaihtoon on helpohko ennustaa liiketoiminnan pysyessä melko vakiona. Tarve voi kuitenkin vaihdella hyvin paljon kysynnän vaihdellessa kuukausi-, viikko- ja päivätasolla. Jos kysyntäennustetta saadaan tarkennettua, lopputuotevaraston kokoa ja siihen sitoutuvaa käyttöpääomaa on mahdollista pienentää, koska varmuusvaraston määrittelyssä käytettävä hajonta pienenee. Myyntisaamisten osalta lähitulevaisuudessa sitoutuvaan käyttöpääomaan vaikuttaa eniten asiakaskohtainen maksukäyttäytyminen, koska myyntisaamisiin vaikuttava kysyntä on suurimmalta osaltaan jo toteutunut.
