Hankintariskienhallinta Suomen IVD-teollisuudessa

Kansainvälinen ja kiristyvä kilpailu on muuttanut yritysten liiketoimintaympäristöä yhä monimutkaisemmaksi ja riskialttiimmaksi. Yritysten keskittyessä yhä syvemmin omaan ydinosaamiseensa on ulkoisten resurssien hallinnan merkitys korostunut. Työnjakoa syventämällä tavoitellaan parempaa joustavuutta, ajanhallintaa sekä kustannustehokkuutta. Myös hankintatoimen tehtävät ja vastuualueet muuttuvat ennakoivampaan ja riskialttiimpaan suuntaan. Modernin hankintatoimen on kyettävä tunnistamaan, analysoimaan ja hallitsemaan riskejä yhä pirstaloituneemmista lähteistä ja muodoista. Proaktiivinen hankintatoimi osallistuu yrityksen strategiseen suunnitteluun ja riskienhallintaan. Hankintariskit voidaan luokitella seuraaviin kymmeneen riskiluokkaan: keskeytymisriskit, saatavuusriskit, hintariskit, varasto- ja aikatauluriskit, teknologiariskit, luottamuksellisen tiedon vuotoriskit, laaturiskit, konfiguraatioriskit, opportunismiriskit sekä riippuvuusriskit. Tässä tutkimuksessa hankintariskienhallintaa tarkastellaan hankintastrategian valinnan näkökulmasta. Hankintastrategian yksi elementti on toimittajasuhteen ja toimittajien lukumäärän valinta. Tilanteesta riippuen yhteistyöstrategialla tai perinteisellä kilpailuttamisella voidaan tavoitella parempaa riskienhallintaa. Yhteistyöstrategioita ovat eri tasoiset kumppanuussuhteet ja liittoutumat, jolloin suhde toimittajaan on syvä ja luottamuksellinen hyödyttäen aidosti molempia osapuolia. Riskienhallinnan näkökulmasta yhteistyöstrategia soveltuu parhaiten tilanteissa, joissa toimittajista on pitkä kokemus sekä hankintanimikkeen tuottama arvo on merkittävä. Kilpailuttamisstrategia eli hankintojen toteuttaminen usealta toimittajalta vaatii ostavalta organisaatiolta tehokkaasti hyödynnettynä suurempia resursseja kuin yhteistyöstrategian käyttö. Kilpailuttaminen soveltuu usein parhaiten silloin, kun hankintanimikkeet ovat tavanomaisia ja vaihtoehtoisia hankintalähteitä on runsaasti. Lisäksi usean toimittajan käyttö suojaa materiaalivirran katkoksilta sekä lisää hankintamarkkinoiden tuntemusta. Empiirisessä tutkimusosassa tutkitaan, miten soveltuviksi riskienhallintamenetelmiksi erilaiset hankintastrategiat koetaan Suomen IVD-teollisuudessa. Lisäksi tunnistetaan Suomen IVD-teollisuudessa merkittävimmiksi koetut hankintariskiluokat sekä selvitetään millä organisaation tasolla hankintariskienhallinta pääasiassa suoritetaan. Lisäksi selvitetään, millä menetelmin hankintariskejä pääasiassa analysoidaan.

Interactions between Polyunsaturated Fatty Acids and Probiotics

The prevalence of inflammatory based diseases has increased in industrialized countries over the last decades. For allergic diseases, two primary hypotheses have been proposed to explain this phenomenon, namely the hygiene and dietary evolution based hypothesis. Particularly, the reduced early exposure to microbes and an increase in the amount of polyunsaturated fatty acids (especially n-6 PUFA) in the diet have been discussed. Often, these two factors have been studied independently, even though both factors have been shown to possess potential health benefits and their mode of action to share similar mechanisms. The hypothesis of the present study was that demonstrate that PUFA and probiotics are not separate entities as such but do interact with each other. In the present study, we investigated whether maternal diet and atopic status influence the PUFA composition of breast milk and serum fatty acids of infants, and whether the fatty acid absorption and utilization of infant formula fatty acids is affected by supplementation of infant formula with probiotic bacteria (Lactobacillus GG and Bifidobacterium lactis Bb-12). Moreover, we investigated the mechanisms by which different PUFA influence the physicochemical and functional properties of probiotics as well as functionality of epithelial cells in vitro. We demonstrated a carry-over effect of dietary fatty acids from maternal diet via breast milk into infants’ serum lipid fatty acids. Our data confirmed the previously shown allergy –related PUFA level imbalances, though it did not fully support the impaired desaturation and elongation capacity hypothesis. We also showed that PUFA incorporation into phospholipids of infants was influenced by probiotics in infant formula in a strain dependent manner. Especially,Bifidobacterium lactis Bb-12 in infant formula promoted the utilization of n-3 PUFA. Mechanistically, we demonstrated that probiotics (Lactobacillus GG, Lactobacillus casei Shirota and Lactobacillus bulgaricus) did incorporate and interconvert exogenous free PUFA in the growth medium into bacterial fatty acids strain and PUFA dependently. In general, high concentrations of free PUFA inhibited the growth and mucus adhesion of probiotics, whereas low concentrations of specific long chain PUFA were found to promote the growth and mucus adhesion of Lactobacillus casei Shirota. These effects were paralleled with only minor alterations in hydrophobicity and electron donor – electron acceptor properties of lactobacilli. Furthermore, free PUFA were also demonstrated to alter the adhesion capacity of the intestinal epithelial cells; n-6 PUFA tended to inhibit the Caco-2 adhesion of probiotics, whereas n-3 PUFA had either no or minor effects or even promote the bacterial adhesion (especially Lactobacillus casei Shirota) to PUFA treated Caco-2 cells. The results of this study demonstrate the close and bilateral interactions between dietary PUFA and probiotics. Probiotics were shown to influence the absorption and utilization of dietary PUFA, whereas PUFA were shown to alter the functional properties of both probiotics and mucosal epithelia. These findings suggest that a more thorough understanding of interactions between PUFA and intestinal microbiota is a prerequisite, when the beneficial effects of new functional foods containing probiotics are designed and planned for human intervention studies.

Eteläisten merirajojen vaikutus Euroopan unionin rajaturvallisuuden kehitykselle

Euroopan unionin keskeisimpiä tavoitteita on ollut luoda sisärajaton alue, jossa kansalaiset voivat liikkua, asua ja työskennellä vapaasti luottaen siihen, että heidän turvallisuutensa on taattu. Vuonna 1985 viisi Eurooppalaista valtiota allekirjoitti Schengen-sopimuksen, jolla poistettiin rajatarkastukset sopimusmaiden välisiltä rajoilta. Schengen-sopimus liitettiin osaksi Euroopan unionin perussopimusta vuonna 1999 allekirjoitetulla Amsterdamin sopi-muksella. Oikeuteen, vapauteen ja turvallisuuteen perustuvan sisärajattoman Schengen-alueen turvallisuuden ylläpitäminen edellyttää jatkuvaa yhteistyötä ja solidaarista vastuun-jakoa sopimusvaltioiden kesken. Sisärajattoman alueen muodostaminen johti uudentyyppisiin valtioiden sisäisen turvalli-suuden uhkiin. Erityisesti EU:n eteläisiin merirajoihin rajoittuvissa jäsenvaltioissa modernit rajaturvallisuuden uhkakuvat konkretisoituvat jatkuvina laajamittaisina maahantulovirtoina. Vastatakseen lisääntyneeseen turvallisuusvajeeseen EU perusti vuonna 2004 jäsenvaltioi-densa operatiivisesta ulkorajayhteistyöstä huolehtivan viraston (Frontex). Frontexin pääteh-tävänä on tukea EU:n ulkorajojen valvontaa toteuttamalla riskianalyysiin perustuvia yhteis-operaatioita. Yhteisoperaation järjestävä jäsenvaltio vastaa rajavalvontatehtävien johtami-sesta ja Frontex jäsenvaltioiden yhteistoiminnan koordinoinnista. Frontexin koordinoimien merellisten yhteisoperaatioiden merkitys on korostunut unionin poliittisella agendalla eri-tyisesti Italian Lampedusan traagisten tapahtumien johdosta. Tutkimus on luonteeltaan kvalitatiivinen tutkimus. Tutkimuksen tarkoitus on deduktiivisen analyysin kautta selvittää Frontexin toimintaa unionin eteläisillä merirajoilla. Tutkimukses-sa selvitetään uusfunktionalistisen teorian spill over –mekanismin ilmentymistä eurooppa-laisen rajaturvallisuuden integraatiossa. Tutkimuksessa selvitetään lisäksi EU:n rajaturvallisuuden kehittymistä ja arvioidaan Fron-texin koordinoimien merellisten yhteisoperaatioiden vaikutusta unionin jäsenvaltioille. Tutkimuksen primääriaineisto muodostuu Eurooppa-neuvoston, Euroopan komission ja Frontexin asiakirjoista ja vuosiraporteista.

Fronteras y oportunidades de integración: los recursos subterráneos de agua dulce en el Mercosur

El presente estudio de caso tiene como objetivo analizar la influencia del Sistema Acuífero Guaraní (SAG), en la agenda de integración del MERCOSUR. Se argumenta que el SAG al considerarse un espacio estratégico trasfronterizo, cuenta con un potencial desestabilizador, pero a la vez se configura como un potencial armonizador de la agenda de integración de MERCOSUR, analizando que esta característica promueve el fortalecimiento de los lazos de cooperación y el establecimiento de una dimensión ambiental al interior de la agenda. Para comprobarlo, se revisará el concepto de agenda y se utilizaran los conceptos de integración y desbordamiento del neofuncionalismo en el contexto de la interdependencia compleja. Finalmente, se avanza hacia el resultado de la investigación que permite entender como el carácter estratégico del agua permea la agenda del MERCOSUR.

Preparing for a post-Assad Syria: What role for the European Union? CEPS Commentary, 2 August 2012

In this CEPS Commentary, Steven Blockmans notes that a prolonged period of instability lies ahead for Syria, with an on-going risk of spill-over effects affecting the entire region. The author argues that the EU’s plans for a post-Assad Syria should extend beyond the half-hearted responses to the monumental changes that have ripped through other parts of the Arab world. In recognition of the geostrategic shifts in the Middle East and the Gulf, and pursuant to the obligation imposed upon it by the Lisbon Treaty, the EU should plan for the creation of a regional space of shared security. Such a plan would fit well into the current efforts to revamp the European Security Strategy.

The Gulf Cooperation Council as a New Regional Power: Time for the EU to Propose a Strategic Partnership. Bruges Regional Integration & Global Governance Papers 3/2012, November 2012

The Gulf Cooperation Council (GCC) is a de facto regional power in the Arab world. Its role has been crucial in some of the outcomes of the Arab Spring. The GCC countries have been very pragmatic in dealing with the uprisings, avoiding any revolutionary spill-over throughout the Gulf region. This paper examines to what extent the policies of the European Union (EU) in the Gulf have changed since the beginning of the Arab Spring. It argues that despite the calls by the European Parliament and by the High Representative Baroness Ashton to improve the relationship, the EU’s support for a new policy in the Gulf after the Arab Spring is stalling, and little new or concrete has been achieved. The paper concludes that the Union needs a reinforced partnership that merges the various EU policies in the region into a single strategic partnership with the Arab countries.

Small towns as 'sub-poles' in English rural development: Investigating rural-urban linkages using sub-regional social accounting matrices

This paper uses spatial economic data from four small English towns to measure the strength of economic integration between town and hinterland and to estimate the magnitude of town-hinterland spill-over effects. Following estimation of local integration indicators and inter-locale flows, sub-regional social accounting matrices (SAMs) are developed to estimate the strength of local employment and output multipliers for various economic sectors. The potential value of a town as a 'sub-pole' in local economic development is shown to be dependent on structural differences in the local economy, such as the particular mix of firms within towns. Although the multipliers are generally small, indicating a low level of local linkages, some sectors, particularly financial services and banking, show consistently higher multipliers for both output and employment.

On the relationship between the Indian summer monsoon and river flow in the Aral Sea basin

We study the contemporaneous relationship between the intensity of the Indian Summer Monsoon (ISM) and runoff in the major rivers of the Aral Sea basin (Amudarya, Syrdarya) and some of their subcatchments. To this end, we use All-India rainfall (AIR) data, CRU surface observations of precipitation and temperature, ERA40 atmospheric data, and natural discharge data corrected for human interference. We show that there is a highly significant positive correlation between ISM intensity and Amudarya runoff. This finding cannot be explained by the spill-over of ISM precipitation over the Hindu Kush into the Amudarya basin. Instead, we suggest that the observed co-variability is mediated by tropospheric temperature variations due to fluctuations in the ISM intensity. These variations are known to be due to Rossby-wave propagation in response to condensational heating during monsoon precipitation. We hypothesise that the corresponding anomalies in surface temperatures imply anomalies in meltwater formation.

Innovation in construction: a sociology of technology approach

An alternative approach to understanding innovation is made using two intersecting ideas. The first is that successful innovation requires consideration of the social and organizational contexts in which it is located. The complex context of construction work is characterized by inter-organizational collaboration, a project-based approach and power distributed amongst collaborating organizations. The second is that innovations can be divided into two modes: ‘bounded’, where the implications of innovation are restricted within a single, coherent sphere of influence, and ‘unbounded’, where the effects of implementation spill over beyond this. Bounded innovations are adequately explained within the construction literature. However, less discussed are unbounded innovations, where many firms' collaboration is required for successful implementation, even though many innovations can be considered unbounded within construction's inter-organizational context. It is argued that unbounded innovations require an approach to understand and facilitate the interactions both within a range of actors and between the actors and technological artefacts. The insights from a sociology of technology approach can be applied to the multiplicity of negotiations and alignments that constitute the implementation of unbounded innovation. The utility of concepts from the sociology of technology, including ‘system building’ and ‘heterogeneous engineering’, is demonstrated by applying them to an empirical study of an unbounded innovation on a major construction project (the new terminal at Heathrow Airport, London, UK). This study suggests that ‘system building’ contains outcomes that are not only transformations of practices, processes and systems, but also the potential transformation of technologies themselves.

Does high-frequency repetitive transcranial magnetic stimulation produce residual and/or cumulative effects within an experimental session?

A common procedure for studying the effects on cognition of repetitive transcranial magnetic stimulation (rTMS) is to deliver rTMS concurrent with task performance, and to compare task performance on these trials versus on trials without rTMS. Recent evidence that TMS can have effects on neural activity that persist longer than the experimental session itself, however, raise questions about the assumption of the transient nature of rTMS that underlies many concurrent (or "online") rTMS designs. To our knowledge, there have been no studies in the cognitive domain examining whether the application of brief trains of rTMS during specific epochs of a complex task may have effects that spill over into subsequent task epochs, and perhaps into subsequent trials. We looked for possible immediate spill-over and longer-term cumulative effects of rTMS in data from two studies of visual short-term delayed recognition. In 54 subjects, 10-Hz rTMS trains were applied to five different brain regions during the 3-s delay period of a spatial task, and in a second group of 15 subjects, electroencephalography (EEG) was recorded while 10-Hz rTMS was applied to two brain areas during the 3-s delay period of both spatial and object tasks. No evidence for immediate effects was found in the comparison of the memory probe-evoked response on trials that were vs. were not preceded by delay-period rTMS. No evidence for cumulative effects was found in analyses of behavioral performance, and of EEG signal, as a function of task block. The implications of these findings, and their relation to the broader literature on acute vs. long-lasting effects of rTMS, are considered.

Commercial real estate and equity market bubbles: are they contagious to REITs?

This paper uses a regime-switching approach to determine whether prices in the US stock, direct real estate and indirect real estate markets are driven by the presence of speculative bubbles. The results show significant evidence of the existence of periodically partially collapsing speculative bubbles in all three markets. A multivariate bubble model is then developed and implemented to evaluate whether the stock and real estate bubbles spill over into REITs. The underlying stock market bubble is found to be a stronger influence on the securitised real estate market bubble than that of the property market. Furthermore, the findings suggest a transmission of speculative bubbles from the direct real estate to the stock market, although this link is not present for the returns themselves.

Speculative bubble spillovers across regional housing markets

In this paper we determine whether speculative bubbles in one region in the United States can lead bubbles to form in others. We first apply a regime-switching model to determine whether speculative bubbles existed in the U.S. regional residential real estate markets. Our findings suggest that the housing markets in five of the nine census divisions investigated were characterized by speculative bubbles. We then examine the extent to which bubbles spill over between neighboring and more distant regions, finding that the transmission of speculative bubbles and nonfundamentals between regions is multidirectional and does not depend on contiguity or distance

Foreign direct investment spillovers: what can we learn from portuguese data?

This paper investigates the impact of foreign direct investment on the productivity performance of domestic firms in Portugal. The data comprise nine manufacturing sectors for the period 1992-95. Relatively to previous studies, model specification is improved by taking into consideration several aspects: the influence of the “technological gap” on spill-overs diffusion and the choice of its most appropriate interval; sectoral variation in the coefficients of the spill-overs effect; identification of constant, idiosyncratic sectoral factors by means of a fixed effects model; and the search for inter-sectoral positive spillover effects. The relationship between domestic firms productivity and the foreign presence does take place in a positive way, only if a proper technology differential between the foreign and domestic producers exists and the sectoral characteristics are favourable. In broad terms, spillovers diffusion is associated to modern industries in which the foreign owned establishments have a clear, but not too sharp, edge on the domestic ones. Besides, other specific sectoral influences can be pertinent; agglomerative location factors being one example.
