Auf dem internationalen Eis : Internationale berufliche Mobilität und Sprachressourcen im Sport
2015
Tässä pro gradu-tutkielmassa käsitellään jääkiekkoilijoiden työperäistä, kansainvälistä liikkuvuutta ja kieliresursseja. Tutkielma on koottu kolmen teemahaastattelun ympärille, jotka käytiin kahden suomalaisen jääkiekkoilijan sekä yhden suomalaisen jääkiekkovalmentajan kanssa Sveitsissä vuoden 2014 tammikuussa. Haastateltavat toimivat haastattelujen aikana jääkiekon parissa Sveitsin NLA-liigassa. Tutkielman näkökulmaksi rajautui siis suomalaisiin jääkiekkotoimijoihin Sveitsissä. Haastattelujen toteuttamiseen sain rahallista avustusta SVFF-yhdistykseltä Sveitsistä. Haastattelut käytiin suomeksi. Aineisto käsiteltiin laadullisen sisällönanalyysin keinoin. Kiinnostus aiheeseen syntyi tehdessän…
Report of toxic shock syndrome toxin 1 (TSST-1) from Staphylococcus aureus isolated in food handlers and surfaces from foodservice establishments.
2012
A set of 53 Staphylococcus aureus isolates collected from food handlers and foodservice establishments in Spain was analyzed for toxic shock syndrome toxin (TSST-1) production. S. aureus strains were isolated from 908 samples collected from different surfaces such as dish towels, workers’ hands, cutting boards, stainless steel tables and slicers, but they were not detected neither in clean plates nor in kitchen knives. Only one food worker hand has been reported to be contaminated by TSST-1 in a restaurant. Despite this, proper hygiene practices should be respected for the surfaces of contact with food, as well as for the hands of the manipulators This is the first article, in Spain, that r…
Mixed Non-Parametric and Parametric Estimation Techniques in R Package etasFLP for Earthquakes’ Description
2017
etasFLP is an R package which fits an epidemic type aftershock sequence (ETAS) model to an earthquake catalog; non-parametric background seismicity can be estimated through a forward predictive likelihood approach, while parametric components of triggered seismicity are estimated through maximum likelihood; estimation steps are alternated until convergence is obtained and for each event the probability of being a background event is estimated. The package includes options which allow its wide use. Methods for plot, summary and profile are defined for the main output class object. The paper provides examples of the package's use with description of the underlying R and Fortran routines.
Windowed Etas Models With Application To The Chilean Seismic Catalogs
2015
Abstract The seismicity in Chile is estimated using an ETAS (Epidemic Type Aftershock sequences) space–time point process through a semi-parametric technique to account for the estimation of parametric and nonparametric components simultaneously. The two components account for triggered and background seismicity respectively, and are estimated by alternating a ML estimation for the parametric part and a forward predictive likelihood technique for the nonparametric one. Given the geographic and seismological characteristics of Chile, the sensitivity of the technique with respect to different geographical areas is examined in overlapping successive windows with varying latitude. A different b…
Phytochemical Profile and Apoptotic Activity of Onopordum cynarocephalum.
2012
A phytochemical investigation of acetone and chloroform extracts of the aerial parts of Onopordum cynarocephalum Boiss. et Blanche was carried out. It led to the isolation of two new sesquiterpenes, the elemane aldehyde (2) and the eudesmane (11), together with 15 known compounds: two lignans (1 and 15) and 13 sesquiterpenes (3–10, 12–14, 16, 17). The structures were elucidated by spectroscopic analyses, especially 1D and 2D NMR spectra. The anti-growth effect against three human melanoma cell lines, M14, A375, and A2058, of the different extracts and compounds of O. cynarocephalum was also investigated. Among them, the chloroform extract exhibited the strongest biological activity, while t…
Intratumoral Heterogeneity for hsp90β mRNA Levels in a Breast Cancer Cell Line
1997
BC-3A and BC-61 are two breast cancer cell lines that have been cloned from parental 8701-BC cells and exhibit different biosynthetic, proliferative, and invasive properties in vitro. In the attempt to search whether alterations in the profiles of gene expression could be detected, we have submitted both cytotypes to identification of differentially expressed cDNAs. In addition, steroid hormone receptor mRNA arrays and in vivo tumorigenesis of the two lines have been checked. The technique used allowed identification of changes in the expression of the 90-kD heat shock protein-beta (hsp90beta) which is prominently down-regulated in BC-61 cells. Because we have also found that these cells, w…
Can fiscal policy stimulus boost economic recovery
2011
We assess the role played by fiscal policy in explaining the dynamics of asset markets. Using a panel of ten industrialized countries, we show that a positive fiscal shock has a negative impact in both stock and housing prices. However, while stock prices immediately adjust to the shock and the effect of fiscal policy is temporary, housing prices gradually and persistently fall. Consequently, the attempts of fiscal policy to mitigate stock price developments (e.g. via taxes on capital gains) may severely de-stabilize housing markets. The empirical findings also point to significant fiscal multiplier effects in the context of severe housing busts, which gives rise to the importance of the im…
Assessment of metallic materials required for shock stress protection
2017
Establishing which metallic materials are suitable to be used for the protection of operators and machinery, when subjected to stress impact in the drilling industry, for surface exploitation, mines and quarries, is a complex process. Due to the harsh operating conditions, a careful evaluation of the various materials used is of utmost importance. This paper addresses the issues relating to the methodology of determining the appropriate homogenous materials to be used, based on a correspondence between their characteristics and applications. Starting with a list of specific operating conditions, one has established a set of requirements and has assessed the market; the recommended materials…
Heterogeneous Displacement Effects of Migrant Labor Supply – Quasi-Experimental Evidence From Germany
2019
We provide estimates of the effect of migrant labor supply on resident employment. We exploit variation in the number of asylum seekers eligible to the suspension of a major hiring restriction implemented in a subset of German counties. Our difference-in-difference design allows us to provide evidence from a labor supply shock of migrants on local markets net of their additional spending at arrival that might mask labor market displacement effects. Despite this, we do not find a negative effect on employment growth of natives but only on other foreign residents. This also holds for unskilled employees. Therefore, our findings can be interpreted as the consequence of differential substitutab…
Market efficiency and the long-memory of supply and demand: is price impact variable and permanent or fixed and temporary?
2016
In this comment we discuss the problem of reconciling the linear efficiency of price returns with the long-memory of supply and demand. We present new evidence that shows that efficiency is maintained by a liquidity imbalance that co-moves with the imbalance of buyer vs. seller initiated transactions. For example, during a period where there is an excess of buyer initiated transactions, there is also more liquidity for buy orders than sell orders, so that buy orders generate smaller and less frequent price responses than sell orders. At the moment a buy order is placed the transaction sign imbalance tends to dominate, generating a price impact. However, the liquidity imbalance rapidly incre…
