    The Portability of New Immigrants' Human Capital: Language, Education and Occupational Matching

    The implications of human capital portability – including interactions between education, language skills and pre- and post-immigration occupational matching – for earnings are explored for new immigrants to Canada. Given the importance of occupation-specific skills, as a precursor we also investigate occupational mobility and observe convergence toward the occupational skill distribution of the domestic population, although four years after landing immigrants remain less likely have a high skilled job. Immigrants who are able to match their source and host country occupations obtain higher earnings. However, surprisingly, neither matching nor language skills have any impact on the return to pre-immigration work experience, which is observed to be statistically significantly negative. Crucially, English language skills are found to have an appreciable direct impact on earnings, and to mediate the return to pre-immigration education but not labour market experience.immigration, human capital portability, occupation, language, education

    The Economic Return on New Immigrants' Human Capital: the Impact of Occupational Matching

    Get PDF
    Using a data set that provides information on source country employment, we examine the effect of source and host country occupational matching on earnings and the economic rate of return to the foreign human capital of immigrants in Canada. Examining occupational distributions we find that immigrants converge very quickly to the skill distribution of the Canadian population in terms of the main job worked, although four years after landing they are still below the source country distribution. We also find that for a large proportion of immigrants, their intended occupation differs from their source country occupation. Although immigrants who are able to match their source and host country occupations obtain higher earnings, successful occupational matching does not have any impact on the return to foreign potential work experience. However, immigrants who match their source and host country occupations do have a higher return to schooling, particularly for females.Immigrants, Occupational Matching, Human Capital, Canada

    Prion diseases are efficiently transmitted by blood transfusion in sheep

    The emergence of variant Creutzfeld-Jakob disease, following on from the bovine spongiform encephalopathy (BSE) epidemic, led to concerns about the potential risk of iatrogenic transmission of disease by blood transfusion and the introduction of costly control measures to protect blood supplies. We previously reported preliminary data demonstrating the transmission of BSE and natural scrapie by blood transfusion in sheep. The final results of this experiment, reported here, give unexpectedly high transmission rates by transfusion of 36% for BSE and 43% for scrapie. A proportion of BSE-infected tranfusion recipients (3 of 8) survived for up to 7 years without showing clinical signs of disease. The majority of transmissions resulted from blood collected from donors at more than 50% of the estimated incubation period. The high transmission rates and relatively short and consistent incubation periods in clinically positive recipients suggest that infectivity titers in blood were substantial and/or that blood transfusion is an efficient method of transmission. This experiment has established the value of using sheep as a model for studying transmission of variant Creutzfeld-Jakob disease by blood products in humans. (Blood. 2008; 112: 4739-4745

    Different forms of the bovine PrP gene have five or six copies of a short, G-C-rich element within the protein-coding exon

    Current models of the virus-like agents of scrapie and bovine spongiform encephalopathy (BSE) have to take into account that structural changes in a host-encoded protein (PrP protein) exhibit an effect on the time course of these diseases and the survival time of any man or animal exposed to these pathogens. We report here the sequence of different forms of the bovine PrP gene which contain either five or six copies of a short, G-C-rich element which encodes the octapeptide Pro-His-Gly-Gly-Gly-Trp-Gly-Gln or its longer variants Pro-Gln/His-Gly-Gly-Gly-Gly-Trp-Gly-Gln. Out of 12 cattle, we found eight animals homozygous for genes with six copies of the Gly-rich peptide (6:6), while four were heterozygous (6:5). Two confirmed cases of BSE occurred in (6: 6) homozygous animals. Bovine spongiform encephalopathy (BSE) is a transmissible disease (Fraser et al., 1988; Dawson et al., 1990; Barlow & Middleton, 1990) which produces neuropathological lesions in cattle similar to those seen in ovine scrapie (Wells et al., 1987) and the rare human dementias Creutzfeldt-Jakob disease (CJD) and Gerstmann-Str/iussler syndrome (GSS) (Beck & Daniel, 1987). A cellular membrane protein (PrP) has a key role in the transmission and development of these diseases. This protein accumulates in the brain and other tissues during the protracted time course of these diseases and, in a disease-specific, protease-resistant isoform (SAF-PrP), has been purified by subcellular fractionation of scrapie

    Assessing Manganese Concentrations in Groundwater Across the Shenandoah Valley, VA

    Aqueous manganese (Mn2+) in groundwater used for drinking water has adverse aesthetic effects at concentrations ≥ 50 ppb and adverse human health effects at concentrations ≥ 100 ppb. Mn2+ in groundwater may have anthropogenic (mines, pesticide, gasoline) or geogenic (rocks and minerals) sources. Private drinking water wells are vulnerable to Mn2+ contamination because their water quality is not routinely monitored. This study uses groundwater data from 1587 private wells in the Shenandoah Valley, VA to assess the spatial distribution of Mn2+ in groundwater and identify possible Mn2+ contamination mechanisms. Using geospatial and statistical analyses I found that samples collected near the valley center predominantly in shale host lithologies contained Mn2+ ≥ 50 ppb more frequently (26%) than sandstone (25%), metamorphic (13%), limestone (3%), dolostone (2%), igneous (0%), and black shale (0%) lithologies. Additionally, samples collected in closer proximity to surface water had higher Mn2+ concentrations. Groundwater samples with elevated Mn2+ (≥ 100 ppb) occurred on average 206 m from surface water as opposed to 304 m on average for low Mn2+ samples (≤ 100 ppb). Our data suggest that elevated Mn2+ in groundwater occurs near rivers at the valley center where old, anoxic groundwater upwells and reductively dissolves Mn oxides in soils and sediment. Overall, those who source drinking water from wells in the Shenandoah Valley should be cautious of consuming untreated water within shale lithologies

    Enhancing visitor experience in museums and monuments through technology: consumer demand

    Get PDF
    This thesis intends to analyze the use of technology in museums and monuments to strengthen the tourism experience, with emphasis on Portugal. Previous literature tackles this subject on a broad basis, an issue this thesis addresses. Hence, how can Turismo de Portugal enhance visitor experience in museums and monuments through technology? We advocate for Portugal’s museums and monuments to explore the value of technology in today’s world. By surveying related consumers, we demonstrate there is demand for technological enhancements within cultural spaces. The significance of this study is that it informs our theoretical understanding that visitors wish for technology in cultural sites
