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.

Anti-Rickettsia spp. antibodies in free-ranging and captive capybaras from southern Brazil

Capybaras (Hydrochaeris hydrochaeris) are among the main hosts of Amblyomma spp. ticks, which is able to transmit Rickettsia species to human beings and animals. Since they are often infested with potential vector ticks, capybaras may be used as sentinels for rickettsiosis, such as the Brazilian Spotted Fever. The aim of the present study was to determine the prevalence of antibodies against Rickettsia spp. using the indirect immunofluorescence assay (IFA) in 21 free-ranging and 10 captive animals from the Zoological Park of the 'Bela Vista Biological Sanctuary' (BVBS), Itaipu Binational, Foz do Iguaçu, Southern Brazil. Antigens of six rickettsial species already identified in Brazil (Rickettsia rickettsii, R. parkeri, R. bellii, R. rhipicephali, R. amblyommii and R. felis) were used for IFA. Ticks from each capybara were collected for posterior taxonomic identification. A total of 19 (61.3%) samples reacted to at least one of tested species. Seropositivity was found in 14 (45.2%), 12 (38.7%), 5 (16.1%), 4 (12.9%), 3 (9.7%) and 3 (9.7%) animals for R. rickettsii, R. bellii, R. parkeri, R. amblyommii, R. felis and R. rhipicephali, respectively. Two captive capybaras presented suggestive titers of R. rickettsii infection and one sample showed homologous reaction to R. parkeri. Only one free-ranging capybara presented evidence R. bellii infection. Ticks collected on capybaras were identified as Amblyomma dubitatum e Amblyomma sp. Results evidenced the rickettsial circulation in the area, suggesting a potential role of capybaras on bacterial life cycle.

Effect of Lactobacillus delbrueckii on cholesterol metabolism in germ-free mice and on atherogenesis in apolipoprotein E knock-out mice

Elevated blood cholesterol is an important risk factor associated with atherosclerosis and coronary heart disease. Several studies have reported a decrease in serum cholesterol during the consumption of large doses of fermented dairy products or lactobacillus strains. The proposed mechanism for this effect is the removal or assimilation of intestinal cholesterol by the bacteria, reducing cholesterol absorption. Although this effect was demonstrated in vitro, its relevance in vivo is still controversial. Furthermore, few studies have investigated the role of lactobacilli in atherogenesis. The aim of the present study was to determine the effect of Lactobacillus delbrueckii on cholesterol metabolism in germ-free mice and the possible hypocholesterolemic and antiatherogenic action of these bacteria using atherosclerosis-prone apolipoprotein E (apo E) knock-out (KO) mice. For this purpose, Swiss/NIH germ-free mice were monoassociated with L. delbrueckii and fed a hypercholesterolemic diet for four weeks. In addition, apo E KO mice were fed a normal chow diet and treated with L. delbrueckii for 6 weeks. There was a reduction in cholesterol excretion in germ-free mice, which was not associated with changes in blood or liver cholesterol concentration. In apo E KO mice, no effect of L. delbrueckii was detected in blood, liver or fecal cholesterol. The atherosclerotic lesion in the aorta was also similar in mice receiving or not these bacteria. In conclusion, these results suggest that, although L. delbrueckii treatment was able to reduce cholesterol excretion in germ-free mice, no hypocholesterolemic or antiatherogenic effect was observed in apo E KO mice.

From Fordism to neoconservatism : free trade and Canadian industrial policy in an era of globalism /

Nothing today affects the lives of people in countries throughout the industrialized and developing world as much as international trade. Nowhere is this more true than in Canada. Canada's involvement in international trade has a long history dating back to 1854 when it was a British colony. As a major trading country, Canada has always adopted a proactive industrial policy which has been largely responsible for its relative economic prosperi ty. But, wi th businesses now free to invest and divest under the terms of the CUFTA and the NAFTA, the most fundamental concerns for Canadians, in a borderless world, are what powers will the Canadian government have to shape industrial policy, and to what extent can Canada continue as a viable nationstate if it can no longer control its national economy? These are important concerns because, in world without borders, the adjustment process becomes more volatile and more difficult to manage. The CUFTA and the NAFTA not only create the rules for conducting trade, but they also establish a set of new rules for the Canadian government that will diminish its power. As a member of a new North American trading bloc, Canada will find itself subject to a set of forces requiring analysis beyond participation in a conventional free trade area. Because many of the traditional levers of government will now be subject to external control imposed by these agreements, Canada will not be able to mount certain policies in the future that it has relied on in the past. This reality limits the pro-active role of the Canadian state to use policies and programmes for the country's immediate national development. What this thesis attempts is an examination of the evolution of Canadian industrial policy, in effect, the transi tion from Fordism to Neoconservatism, and an assessment of Canada's future as a nation-state as it tries to find security and improved access in a free trade arrangement. Unless Canada takes steps to neutralize the asymmetry of power between itself and the United States through adjustment programmes, it is the contention of this thesis that its economic future is anything but stable.

Optical absorption studies of free (H2Pc) and rare earth (RePc) phthalocyanine doped borate glasses

Optical absorption studies of free base and rare earth incorporated phthalocyanine doped borate glass matrix are reported for the first lime. The absorption spectra recorded in the UV- VIS region show two well defined absorption bands of phthalocyanine (Pc) molecule, namely the Soret band (B) and the Q band. The Q band always shows its characteristic splitting in all the doped glass matrices and the intensities of these components are found to vary from one Pc to another. Some of the important optical parameters, namely optical absorption coefficient (a), molar extinction coefficient (ε), absorption cross section (σa), oscillator strength (f), electric dipole strength (q2), absorption half bandwidth (Δλ) of the principal optical transitions have also been evaluated. Moreover, the spectral dependence of refractive index (n) and thereby the optical dielectric constant (ε) on wavelength yielded values of carrier concentration to effective mass ratio (N/m*) of the phthalocyanine molecule in the present glassy systems. Optical band gap (Eg) and width of the band tail (Et) are computed and their variations among the prepared samples are also discussed.

Lithography-free micro- and nanostructuring based on conventional plasma etching

In now-a-days semiconductor and MEMS technologies the photolithography is the working horse for fabrication of functional devices. The conventional way (so called Top-Down approach) of microstructuring starts with photolithography, followed by patterning the structures using etching, especially dry etching. The requirements for smaller and hence faster devices lead to decrease of the feature size to the range of several nanometers. However, the production of devices in this scale range needs photolithography equipment, which must overcome the diffraction limit. Therefore, new photolithography techniques have been recently developed, but they are rather expensive and restricted to plane surfaces. Recently a new route has been presented - so-called Bottom-Up approach - where from a single atom or a molecule it is possible to obtain functional devices. This creates new field - Nanotechnology - where one speaks about structures with dimensions 1 - 100 nm, and which has the possibility to replace the conventional photolithography concerning its integral part - the self-assembly. However, this technique requires additional and special equipment and therefore is not yet widely applicable. This work presents a general scheme for the fabrication of silicon and silicon dioxide structures with lateral dimensions of less than 100 nm that avoids high-resolution photolithography processes. For the self-aligned formation of extremely small openings in silicon dioxide layers at in depth sharpened surface structures, the angle dependent etching rate distribution of silicon dioxide against plasma etching with a fluorocarbon gas (CHF3) was exploited. Subsequent anisotropic plasma etching of the silicon substrate material through the perforated silicon dioxide masking layer results in high aspect ratio trenches of approximately the same lateral dimensions. The latter can be reduced and precisely adjusted between 0 and 200 nm by thermal oxidation of the silicon structures owing to the volume expansion of silicon during the oxidation. On the basis of this a technology for the fabrication of SNOM calibration standards is presented. Additionally so-formed trenches were used as a template for CVD deposition of diamond resulting in high aspect ratio diamond knife. A lithography-free method for production of periodic and nonperiodic surface structures using the angular dependence of the etching rate is also presented. It combines the self-assembly of masking particles with the conventional plasma etching techniques known from microelectromechanical system technology. The method is generally applicable to bulk as well as layered materials. In this work, layers of glass spheres of different diameters were assembled on the sample surface forming a mask against plasma etching. Silicon surface structures with periodicity of 500 nm and feature dimensions of 20 nm were produced in this way. Thermal oxidation of the so structured silicon substrate offers the capability to vary the fill factor of the periodic structure owing to the volume expansion during oxidation but also to define silicon dioxide surface structures by selective plasma etching. Similar structures can be simply obtained by structuring silicon dioxide layers on silicon. The method offers a simple route for bridging the Nano- and Microtechnology and moreover, an uncomplicated way for photonic crystal fabrication.

Factors associated to avascular necrosis of the femoral head and non-union in patients younger than 65 years old with displaced femoral neck fractures treated with reduction and internal fixation.

Pocos estudios han evaluado el tratamiento de las fracturas desplazadas de cuello femoral en pacientes menores de 65 años de edad, y no han sido claramente definidos los factores de riesgo para necrosis avascular o no-unión dentro de este rango de edad. Para determinar los factores asociados a la necrosis avascular de la cabeza femoral (AVN) y no-unión en pacientes menores de 65 años de edad con fracturas desplazadas del cuello femoral tratados con reducción y fijación interna, se realizó un estudio retrospectivo de 29 fracturas desplazadas del cuello femoral en 29 pacientes consecutivos tratados en una sola institución. La influencia de la edad, la energía del trauma, tipo de reducción, y el tiempo entre la fractura y el tratamiento en desarrollo de la AVN y no-unión fueron evaluados. Los pacientes que desarrollaron NAV fueron significativamente mayores y sufrieron un trauma de más baja energía que en los casos sin AVN. Ninguna variable fue asociada con la no-unión. La regresión logística determinó que sólo la edad se asoció de forma independiente a NAV. La edad es un buen predictor para el desarrollo de NAV, con un C-estadístico de 0.861, y un mejor corte-determinado en 53,5 años. Conclusión: Los pacientes de entre 53,5 y 65 años presentan un riesgo más alto de NAV. La artroplastia primaria se debe considerar en este subgrupo.

Students’ movement and participation in Latin-American psychology: historical and future perspectives

The historiographical paper presented is about the students’ activism and participation in the Latin American psychology. This aims are: 1) to provide a brief historic overview of the Latin American psychology; 2) to review on the students’ participation in the Latin American psychology; 3) to raise students’ future perspectives for the Latin American psychology. It is recognized that there is an extensive past of Latin American psychology and an emerging historiographical work that re fl ects that past.However, there are several historiographical gaps not covered yet by the investigations in the region. In this context, this paper wants to contribute to the study of the students’ activism and participation in the Latin American psychology construction. The historical perspective is supported by the renewed historiographical conception called instant history” which focuses on ancient and recent history at the same time. Indirect sources were used: articles, monographs and compiled editions.

Banking Union in the Eurozone and the European Union. CEPS Commentary, 12 June 2012

In this new CEPS Commentary, Jacopo Carmassi, Carmine Di Noia and Stefano Micossi present a rationale and detailed outline for the creation of a banking union in Europe. They argue that it is essential to clearly distinguish between what is needed to address a ‘systemic’ confidence crisis hitting the banking system – which is mainly or solely a eurozone problem – and ‘fair weather’ arrangements to prevent individual bank crises and, when they occur, to manage them in an orderly fashion so as to minimise systemic spillovers and the cost to taxpayers, which is of concern for the entire European Union.
