Ulkomaalaiset vuokratyöntekijät Suomessa yrityksen näkökulma

Tutkimuksessa selvitetään, mitä yrityksen tulee ottaa huomioon ulkomaalaista vuokratyövoimaa käyttäessään. Suomea uhkaavan työvoimapulan ehkäisemiseksi tarvitsemme työperäistä maahanmuuttoa. Joillakin aloilla työvoimapulasta kärsitään jo nyt. Ulkomaalaisten osuus Suomen väestöstä on viime vuosina nopeasti kasvanut, mutta muualta tulleiden sopeuttamisessa on ollut puutteita. Vuokratyöntekijöiden määrä on noussut viimeisen viiden vuoden aikana, mutta olemme vielä jäljessä Euroopan keskitasosta. Yritykset eivät osaa vielä täysin hyödyntää monikulttuurista työvoimaa. Hyvä kielitaito ja Suomessa hankittu koulutus parantavat ulkomaalaistaustaisen henkilön työnsaantimahdollisuuksia. Vuokratyövoima tarjoaa käyttäjäyritykselle joustavan välineen tuotannon vaihteluihin. Lisäksi työvoiman vapaa liikkuvuus toteutuu Euroopan Unionin alueella varsin hyvin. Toisaalta globaali kilpailu ammattitaitoisista siirtotyöläisistä on kovaa.

Europeanization or Party Politics? Explaining Government Choice for Corporatist Concertation

This article assesses whether changes in government choice for policy concertation with trade unions and employers are better explained by international or domestic factors. We compare patterns of corporatist governance in a strongly Europeanized policy domain (labor migration policy) and in a weakly Europeanized policy domain (welfare state reforms) over the last 20 years in Austria and Switzerland. We show that there is no systematic difference in patterns of concertation between the two policy sectors and that factors linked to party politics play a bigger role in the choice of governments for concertation. If the base of party support for policies is divided, governments are more prone to resort to corporatist concertation as a way to build compromises for potentially controversial or unpopular policies. By contrast, ideologically cohesive majority coalitions are less prone to resort to concertation because they do not need to build compromises outside their base of party support.

Entre culture du consensus et critique sociale : les intellectuels de gauche dans la Suisse de l'après-guerre (1945-1968)

Cette thèse étudie l'engagement des intellectuels de gauche dans la vie politique suisse, de 1945 à 1968. D'une part, il s'agit de retracer l'évolution du statut des intellectuels, que ce soit dans ou hors des partis. D'autre part, il est question d'analyser les débats politiques au sein desquels ces intellectuels furent impliqués, et la manière dont ces débats suscitèrent des clivages entre eux. De ce point de vue, nous mettons en lumière les différents courants et groupes formés par les intellectuels progressistes, souvent structurés autour de revues ; il s'agit aussi bien d'étudier l'engagement de personnalités sociales-démocrates que des communistes prosoviétiques, sans oublier les chrétiens pacifistes ou les intellectuels proches de la gauche radicale antistalinienne. S'agissant de l'évolution du statut des acteurs étudiés, ce travail souligne le déclin de la figure de l'intellectuel de gauche organiquement lié à son parti, souvent issu du milieu ouvrier, au profit d'intellectuels critiques, généralement au bénéfice d'une formation académique et revendiquant une certaine autonomie par rapport aux organisations politiques. Du point de vue des débats politiques, l'engagement des intellectuels de gauche est envisagé à la lumière de trois périodes. Tout d'abord, nous étudions la phase de l'immédiat après-guerre (1945-1949), marquée par une poussée de la gauche, y compris prosoviétique, qui met en cause le conservatisme politique issu des années de Mobilisation. Nous étudions ensuite les années les plus tendues de la guerre froide, entre 1950 et 1962, durant lesquelles la vie politique et intellectuelle en Suisse est dominée par un fort anticommunisme, auquel se rallient les dirigeants du Parti socialiste. Pourtant, l'engagement de certains intellectuels progressistes, en particulier dans le mouvement pacifiste, met en cause le consensus politique de guerre froide. Enfin, dans une troisième partie, nous montrons comment la critique intellectuelle de gauche se renforce après 1962, à la faveur de la détente Est-Ouest sur le plan international, et avec l'essor, en Suisse même, du mouvement des « non- conformistes ». Ce mouvement est animé par des intellectuels qui dénoncent le conservatisme helvétique, les excès de l'anticommunisme ou qui affirment leur solidarité avec les travailleurs immigrés en Suisse, aussi bien qu'avec les mouvements sociaux dans les pays du tiers-monde. Nous montrons en particulier comment l'engagement de ces intellectuels progressistes contribue à préparer le terrain pour les mobilisations de la jeunesse qui surviendront dans les « années 1968 ». -- This thesis adresses the political commitment of left-wing intellectuals in Switzerland between 1945 and 1968. It aims, on the one hand, to examine how the status of intellectuals developed within and outside of political parties. On the other hand, it endeavours to understand the political debates that involved and sometimes split these intellectuals. In this intent, we examine the various political orientations and formations that brought left-wing intellectuals together - often around dedicated periodicals - such as the Social-democratic, the Communist, the Christian Progressist or the anti-Stalinist Marxist movements. Regarding the evolving status of left-wing opinion leaders, we observe the decline of the organic, party-affiliated intellectuals - often from a working class background. By contrast, critical academics - left-wing oriented but.not directly linked to a political formation - became prevailing figures. Concerning left-wing intellectuals' involvement in the political debate, we differentiate three historical periods. Firstly, the immediate postwar years (1945-1949) were characterised by the strengthening of a left-wing faction, including pro-Soviet forces, which criticized the conservative political consensus built up during the War. Secondly, during the most tense years of the Cold War (1950-1962), the Swiss political and intellectual life became widely dominated by a strong anticommunism, supported by the Social-Democratic leaders. Still, the commitment of certain progressist intellectuals, particularly in the pacifist movement, called into question the political consensus resulting from the Cold War. This questioning strengthened after 1962, in the context of the Détente, corresponding to the rise of the "non-conformist" movement. This movement stemmed from progressist intellectuals, who criticized the Swiss conservatism, and the excesses of official anticommunism, while declaring their solidarity with immigrant workers or with the social movements in the Third World. We show in particular how these intellectuals paved the way for the youth mobilization due to occur in the "1968 years".

The effects of some variables on CO2 laser-MAG hybrid welding

The CO2-laser-MAG hybrid welding process has been shown to be a productive choice for the welding industry, being used in e.g. the shipbuilding, pipe and beam manufacturing, and automotive industries. It provides an opportunity to increase the productivity of welding of joints containing air gaps compared with autogenous laser beam welding, with associated reductions in distortion and marked increases in welding speeds and penetration in comparison with both arc and autogenous laser welding. The literature study indicated that the phenomena of laser hybrid welding are mostly being studied using bead-on-plate welding or zero air gap configurations. This study shows it very clearly that the CO2 laser-MAG hybrid welding process is completely different, when there is a groove with an air gap. As in case of industrial use it is excepted that welding is performed for non-zero grooves, this study is of great importance for industrial applications. The results of this study indicate that by using a 6 kW CO2 laser-MAG hybrid welding process, the welding speed may also be increased if an air gap is present in the joint. Experimental trials indicated that the welding speed may be increased by 30-82% when compared with bead-on-plate welding, or welding of a joint with no air gap i.e. a joint prepared as optimum for autogenous laser welding. This study demonstrates very clearly, that the separation of the different processes, as well as the relative configurations of the processes (arc leading or trailing) affect welding performance significantly. These matters influence the droplet size and therefore the metal transfer mode, which in turn determined the resulting weld quality and the ability to bridge air gaps. Welding in bead-onplate mode, or of an I butt joint containing no air gap joint is facilitated by using a leading torch. This is due to the preheating effect of the arc, which increases the absorptivity of the work piece to the laser beam, enabling greater penetration and the use of higher welding speeds. With an air gap present, air gap bridging is more effectively achieved by using a trailing torch because of the lower arc power needed, the wider arc, and the movement of droplets predominantly towards the joint edges. The experiments showed, that the mode of metal transfer has a marked effect on gap bridgeability. Transfer of a single droplet per arc pulse may not be desirable if an air gap is present, because most of the droplets are directed towards the middle of the joint where no base material is present. In such cases, undercut is observed. Pulsed globular and rotational metal transfer modes enable molten metal to also be transferred to the joint edges, and are therefore superior metal transfer modes when bridging air gaps. It was also found very obvious, that process separation is an important factor in gap bridgeability. If process separation is too large, the resulting weld often exhibits sagging, or no weld may be formed at all as a result of the reduced interaction between the component processes. In contrast, if the processes are too close to one another, the processing region contains excess molten metal that may create difficulties for the keyhole to remain open. When the distance is optimised - i.e. a separation of 0-4 mm in this study, depending on the welding speed and beam-arc configuration - the processes act together, creating beneficial synergistic effects. The optimum process separation when using a trailing torch was found to be shorter (0-2 mm) than when a leading torch is used (2-4 mm); a result of the facilitation of weld pool motion when the latter configuration is adopted. This study demonstrates, that the MAG process used has a strong effect on the CO2-laser-MAG hybrid welding process. The laser beam welding component is relatively stable and easy to manage, with only two principal processing parameters (power and welding speed) needing to be adjusted. In contrast, the MAG process has a large number of processing parameters to optimise, all of which play an important role in the interaction between the laser beam and the arc. The parameters used for traditional MAG welding are often not optimal in achieving the most appropriate mode of metal transfer, and weld quality in laser hybrid welding, and must be optimised if the full range of benefits provided by hybrid welding are to be realised.

IN DUBIO PRO NATURA? A Philosophical Analysis of the Precautionary Principle in Environmental and Health Risk Governance

In this book, I apply a philosophical approach to study the precautionary principle in environmental (and health) risk decision-making. The principle says that unacceptable environmental and health risks should be anticipated, and they ought to be forestalled before the damage comes to fruition even if scientific understanding of the risks is inadequate. The study consists of introductory chapters, summary and seven original publications which aim at explicating the principle, critically analysing the debate on the principle, and constructing a basis for the well-founded use of the principle. Papers I-V present the main thesis of this research. In the two last papers, the discussion is widened to new directions. The starting question is how well the currently embraced precautionary principle stands up to critical philosophical scrutiny. The approach employed is analytical: mainly conceptual, argumentative and ethical. The study draws upon Anglo-American style philosophy on the one hand, and upon sources of law as well as concrete cases and decision-making practices at the European Union level and in its member countries on the other. The framework is environmental (and health) risk governance, including the related law and policy. The main thesis of this study is that the debate on the precautionary principle needs to be shifted from the question of whether the principle (or its weak or strong interpretation) is well-grounded in general to questions about the theoretical plausibility and ethical and socio-political justifiability of specific understandings of the principle. The real picture of the precautionary principle is more complex than that found (i.e. presumed) in much of the current academic, political and public debate surrounding it. While certain presumptions and interpretations of the principle are found to be sound, others are theoretically flawed or include serious practical problems. The analysis discloses conceptual and ethical presumptions and elementary understandings of the precautionary principle, critically assesses current practices invoked in the name of the precautionary principle and public participation, and seeks to build bridges between precaution, engagement and philosophical ethics. Hence, it is intended to provide a sound basis upon which subsequent academic scrutiny can build.

Thermoregulation and microhabitat choice in the polymorphic asp viper (Vipera aspis).

In ectotherms, thermoregulation strongly depends on environmental conditions, as well as on intrinsic factors, such as skin colour. Indeed, due to its physical properties, melanin pigments allow melanistic morphs to benefit of a more efficient thermoregulation compared to non-melanistic ones. Despite thermal benefits of melanism have often been highlighted under experimental conditions, such field data remain scarce. In this study, we investigated the influence of colouration on body temperature and microhabitat choice in a montane population of colour polymorphic asp viper (Vipera aspis) characterized by a strong presence of melanism (64%). Results highlighted a difference in internal body temperature, but only within gravid females, with melanistic individuals having higher body temperatures compared to non-melanistic ones. No differences were found when considering both sexes. We also showed that melanistic and non-melanistic vipers were found in different microhabitat types, i.e. melanistic snakes used areas marked by a scarcer sun exposure and by higher vegetation cover compared to non-melanistic ones. This result has important implications. Indeed, besides providing a possible explanation for the lack of difference in body temperature (except for gravid females), it confirms that melanistic individuals can potentially use their efficient thermoregulation in order to inhabit less exposed and thermally unfavourable microhabitats.

The determinants of contractual choice for private involvement in infrastructure projects in the United States

Reliance on private partners to help provide infrastructure investment and service delivery is increasing in the United States. Numerous studies have examined the determinants of the degree of private participation in infrastructure projects as governed by contract type. We depart from this simple public/private dichotomy by examining a rich set of contractual arrangements. We utilize both municipal and state-level data on 472 projects of various types completed between 1985 and 2008. Our estimates indicate that infrastructure characteristics, particularly those that reflect stand alone versus network characteristics, are key factors influencing the extent of private participation. Fiscal variables, such as a jurisdiction’s relative debt level, and basic controls, such as population and locality of government, increase the degree of private participation, while a greater tax burden reduces private participation.

Recovery Risk and Labor Costs in Public-Private Partnerships : Contractual Choice in the US Water industry

We use an ordered logistic model to empirically examine the factors that explain varying degrees of private involvement in the U.S. water sector through public-private partnerships. Our estimates suggest that a variety of factors help explain greater private participation in this sector. We find that the risk to private participants regarding cost recovery is an important driver of private participation. The relative cost of labor is also a key factor in determining the degree of private involvement in the contract choice. When public wages are high relative to private wages, private participation is viewed as a source of cost savings. We thus find two main drivers of greater private involvement: one encouraging private participation by reducing risk, and another encouraging government to seek out private participation in lowering costs.

Pro and con arguments in using alternative dialysis regimens in the frail and elderly patients.

In the last decade, an increasing number of patients over 75 years of age are starting renal replacement therapy. Frailty is highly prevalent in elderly patients with end-stage renal disease (ESRD) in the context of the increased prevalence of some ESRD-associated conditions: protein-energy wasting, inflammation, anaemia, acidosis or hormonal disturbances. There are currently no hard data to support guidance on the optimal duration of dialysis for frail/elderly ESRD patients. The current debate is not about starting dialysis or managing conservatory frail ESRD patients, but whether a more intensive regimen once dialysis is initiated (for whatever reasons and circumstances) would improve patients' outcome. The most important issue is that all studies performed with extended/alternative dialysis regimens do not specifically address this particular type of patients and therefore all the inferences are derived from the general ESRD population. Care planning should be responsive to end-of-life needs whatever the treatment modality. Care in this setting should focus on symptom control and quality of life rather than life extension. We conclude that, similar to the general dialysed population, extensive application of more intensive dialysis schedules is not based on solid evidence. However, after a thorough clinical evaluation, a limited period of a trial of intensive dialysis could be prescribed in more problematic patients.
