Educated Preferences: Explaining Attitudes Toward Immigration in Europe

Recent studies of individual attitudes toward immigration emphasize concerns about labor market competition as a potent source of anti- immigrant sentiment, in particular among less-educated or less-skilled citizens who fear being forced to compete for jobs with low-skilled immigrants willing to work for much lower wages. We examine new data on attitudes toward immigration available from the 2003 European Social Survey. In contrast to predictions based upon conventional arguments about labor market competition, which anticipate that individuals will oppose immigration of workers with similar skills to their own, but support immigration of workers with different skill levels, we find that people with higher levels of education and occupational skills are more likely to favor immigration regardless of the skill attributes of the immigrants in question. Across Europe, higher education and higher skills mean more support for all types of immigrants. These relationships are almost identical among individuals in the labor force (i.e., those competing for jobs) and those not in the labor force. Contrary to the conventional wisdom, then, the connection between the education or skill levels of individuals and views about immigration appears to have very little, if anything, to do with fears about labor market competition. This finding is consistent with extensive economic research showing that the income and employment effects of immigration in European economies are actually very small. We find that a large component of the effect of education on attitudes toward immigrants can be accounted for by differences among individuals in cultural values and beliefs. More educated respondents are significantly less racist and place greater value on cultural diversity; they are also more likely to believe that immigration generates benefits for the host economy as a whole. Together, these factors account for around 65% of the estimated effect of education on support for immigration.Immigration Preferences, Immigration Attitudes, Trade Preferences, Factor-Proportion Model, Education Effects, Skill Effects

Learning to Love Globalization? Education and Individual Attitudes Toward International Trade

Recent studies of public attitudes toward trade have converged upon one central finding: support for trade restrictions is highest among respondents with the lowest levels of education. This has been interpreted as strong support for the Stolper-Samuelson theorem, the classic economic treatment of the income effects of trade which predicts that trade openness benefits those owning factors of production with which their economy is relatively well endowed (those with skills in the advanced economies) while hurting others (low skilled workers). We re- examine the available survey data, showing that the impact of education on attitudes toward trade is almost identical among respondents in the active labor force and those who are not (even those who are retired). We also find that, while individuals with college-level educations are far more likely to favor trade openness than others, other types of education have no significant effects on attitudes, and some actually reduce the support for trade, even though they clearly contribute to skill acquisition. Combined, these results strongly suggest that the effects of education on individual trade preferences are not primarily a product of distributional concerns linked to job skills. We suggest that exposure to economic ideas and information among college-educated individuals plays a key role in shaping attitudes toward trade and globalization. This is not to say that distributional issues are not important in shaping attitudes toward trade – just that they are not clearly manifest in the simple, broad association between education levels and support for free trade.International Trade, Trade Preferences, Stolper-Samuelson, Education Effects

Fungus wars: basidiomycete battles in wood decay

Understanding the mechanisms underlying wood decay basidiomycete community dynamics is crucial for fully understanding decomposition processes, and for modelling ecosystem function and resilience to environmental change. Competition drives community development in decaying woody resources, with interactions occurring at a distance, following physical contact, and through specialised relationships such as mycoparasitism. Outcomes of combative interactions range from replacement, where one mycelium displaces another, to deadlock, where neither combatant captures territory from the other; and a spectrum of intermediate outcomes (i.e. partial or mutual replacement) lie between these extremes. Many wood decay basidiomycetes coexist within a resource, in a complex and dynamic community, and new research techniques are focussing on spatial orientation of interactions in 3 dimensions, as opposed to historical two-dimensional research. Not only do interactions drive changes in species composition and thus wood decomposition rate, they also may have industrial applications in biocontrol of pathogenic or nuisance fungi, enzyme production, and in the production of novel antifungals and antibiotics. Altogether, fungal interactions are a fascinating and important field of study

Written Reflection Influences Science Students’ Perceptions of Their Own and Their Peers’ Teamwork and Related Employability Skills

The impact of written reflection on tertiary students’ self-efficacy, and corresponding evaluation of their peers’ abilities, is often imprecise and lacking in clarity. This study thus sought to assess the effects of a written reflective diary on science undergraduates’ teamwork-related and other employability skills. Employability skills, in particular students’ teamwork-related skills, are crucial to students’ career development and progression. Assessment was carried out using a series of pre- and post-reflection online surveys, the TeamQ assessment rubric, and student focus groups. Participants identified five key teamwork skills, the importance of which remained constant over time. Written reflection had a significant, positive effect on students’ self-efficacy of their oral communication skills. Students’ written reflections were also important in shaping their perceptions about the domain of fostering a team climate, both in terms of their own self-efficacy and perceptions of their peers’ abilities. This study has interesting implications for future research into science students’ teamwork and other employability skills

Commercially available industry-relevant software in the education of genome variant curation

BACKGROUND Genome analytics is a drastically expanding field, and there is an increasing demand for individuals with the necessary skillset to analyse the genome data that is being generated. A new Masters by coursework was developed to train individuals in genome analytics. Institutions analysing genomes commonly utilise in-house analysis tools, but increasingly commercial software packages that integrate AI are being considered in the research and diagnostic space (De La Vega et al., 2021). AIMS Evaluate the effectiveness of commercially available software as a tool for teaching variant analysis, classification and curation, enabling the analysis of real-world case examples for the teaching, training and assessment of students in the field of diagnostic genome analysis.   Assess students’ perspectives on work readiness after using commercially available tools in the educational environment. DESIGN AND METHODS Students were exposed to the use and limitations of a commercial software package for Human genome curation during two core units of the course. This software was used as part of both in-class training and in their assessment case studies. Students were invited to voluntarily complete an online survey including qualitative and quantitative components featuring Likert scale questions, both pre and post exposure to the software. Paired data from 23 individuals (73% response rate), most aged between 18 and 25, were recorded and anonymised prior to analysis. Qualitative data were thematically coded blind by two individuals independently using emergent coding (Charmaz, 2008). RESULTS AND CONCLUSIONS This project indicates that after the completion of the units that integrated commercially available industry software, we measured increased student confidence (increase in percentage reporting fairly confident or higher) in joining the genetic analysis workforce (significant change from 37% to 70%) and in completing job-specific tasks (significant increase in 7 out of 9 tasks of between 28% to 39%). The aspects of their studies the students valued in relation to these changes and their perception of the usefulness of integration of the commercial software were elucidated from qualitative theming, and can inform others looking to integrate commercially available software within their tertiary degree.

Overexpression of CD44 in acquired tamoxifen-resistant breast cancer cells augments their migratory response to heregulin beta 1

Background Acquired endocrine resistance in breast cancer cells is accompanied by altered growth factor receptor signalling [1] and a highly migratory cell phenotype [2]. Interestingly, in tamoxifen-resistant (TamR) MCF7 cells, our microarray analysis has demonstrated elevated levels of CD44, a transmembrane glycoprotein known to interact with, and modulate the function of, growth factor receptors [3]. Here we have explored the role of CD44 as a modulator of heregulin beta-1-induced migratory signalling in TamR cells. Methods Expression of CD44 (standard and v3 isoforms) were confirmed by RT-PCR and western blotting and their association with erbB family members determined by both immunofluorescence microscopy and immunoprecipitation. Activation of intracellular signalling following heregulin beta 1 treatment (10 ng/ml) in the presence or absence of CD44 (using siRNA-mediated inhibition) was determined by western blotting using phosphospecific antibodies. Cellular migration was determined by seeding cells (control and CD44 siRNA-treated) into fibronectin-coated transwell chambers (8.0 μm pore size) in the presence or absence of heregulin beta 1. After 24 hours, migratory cells were fixed, stained with crystal violet and counted. Results Both standard and v3 isoforms of CD44 were overexpressed in TamR cells at both gene and protein levels (mean fold increase in CD44s protein (TamR versus MCF7): 4.26 ± 1.2, P < 0.05). Moreover, CD44s and v3 colocalised with Her2 and Her3 receptors at the cell surface and were also detectable in Her2/Her3 cellular immunoprecipitates. Treatment of TamR cells with heregulin resulted in phosphorylation of erbB receptors together with a number of downstream signalling intermediates, including Akt, Src and FAK, and resulted in enhanced cellular migration. Significantly, heregulin-induced intracellular signalling was dramatically reduced in cells in which the expression of CD44 was suppressed (via siRNA), with a corresponding loss of heregulin-induced migratory behaviour (mean fold change in cell migration versus untreated control: 6.7 ± 1.1, P < 0.05 (heregulin beta 1); 1.8 ± 0.9 (CD44 siRNA); 1.47 ± 0.6, P < 0.05 (heregulin beta 1 + CD44 siRNA)). Conclusion These data demonstrate a role for CD44 as a modulator of erbB receptor function in endocrine-resistant breast cancer cells, where it augments heregulin beta 1 migratory signalling

Evaluating putative repellent 'push' and attractive 'pull' components for manipulating the odour orientation of host-seeking malaria vectors in the peri-domestic space

BACKGROUND: Novel malaria vector control approaches aim to combine tools for maximum protection. This study aimed to evaluate novel and re-evaluate existing putative repellent 'push' and attractive 'pull' components for manipulating the odour orientation of malaria vectors in the peri-domestic space. METHODS: Anopheles arabiensis outdoor human landing catches and trap comparisons were implemented in large semi-field systems to (i) test the efficacy of Citriodiol((R)) or transfluthrin-treated fabric strips positioned in house eave gaps as push components for preventing bites; (ii) understand the efficacy of MB5-baited Suna-traps in attracting vectors in the presence of a human being; (iii) assess 2-butanone as a CO2 replacement for trapping; (iv) determine the protection provided by a full push-pull set up. The air concentrations of the chemical constituents of the push-pull set-up were quantified. RESULTS: Microencapsulated Citriodiol((R)) eave strips did not provide outdoor protection against host-seeking An. arabiensis. Transfluthrin-treated strips reduced the odds of a mosquito landing on the human volunteer (OR 0.17; 95% CI 0.12-0.23). This impact was lower (OR 0.59; 95% CI 0.52-0.66) during the push-pull experiment, which was associated with low nighttime temperatures likely affecting the transfluthrin vaporisation. The MB5-baited Suna trap supplemented with CO2 attracted only a third of the released mosquitoes in the absence of a human being; however, with a human volunteer in the same system, the trap caught < 1% of all released mosquitoes. The volunteer consistently attracted over two-thirds of all mosquitoes released. This was the case in the absence ('pull' only) and in the presence of a spatial repellent ('push-pull'), indicating that in its current configuration the tested 'pull' does not provide a valuable addition to a spatial repellent. The chemical 2-butanone was ineffective in replacing CO2. Transfluthrin was detectable in the air space but with a strong linear reduction in concentrations over 5 m from release. The MB5 constituent chemicals were only irregularly detected, potentially suggesting insufficient release and concentration in the air for attraction. CONCLUSION: This step-by-step evaluation of the selected 'push' and 'pull' components led to a better understanding of their ability to affect host-seeking behaviours of the malaria vector An. arabiensis in the peri-domestic space and helps to gauge the impact such tools would have when used in the field for monitoring or control

Heat Shock Protein 70 family members interact with Crimean-Congo hemorrhagic fever virus and Hazara virus nucleocapsid proteins and perform a functional role in the nairovirus replication cycle

The Nairovirus genus of the Bunyaviridae family contains serious human and animal pathogens classified within multiple serogroups and species. Of these serogroups, the Crimean-Congo hemorrhagic fever virus (CCHFV) serogroup comprises sole members CCHFV and Hazara virus (HAZV). CCHFV is an emerging zoonotic virus that causes often-fatal hemorrhagic fever in infected humans for which preventative or therapeutic strategies are not available. In contrast HAZV is non-pathogenic to humans, and thus represents an excellent model to study aspects of CCHFV biology under more accessible biological containment. The three RNA segments that form the nairovirus genome are encapsidated by the viral nucleocapsid protein (N) to form ribonucleoprotein (RNP) complexes that are substrates for RNA synthesis and packaging into virus particles. We used quantitative proteomics to identify cellular interaction partners of CCHFV N, and identified robust interactions with cellular chaperones. These interactions were validated using immunological methods, and the specific interaction between native CCHFV N and cellular chaperones of the HSP70 family was confirmed during live CCHFV infection. Using infectious HAZV we showed for the first time that the nairovirus N-HSP70 association was maintained within both infected cells and virus particles, where N is assembled as RNPs. Reduction of active HSP70 levels in cells using small molecule inhibitors significantly reduced HAZV titres, and a model for chaperone function in the context of high genetic variability is proposed. These results suggest chaperones of the HSP70 family are required for nairovirus replication and thus represent a genetically stable cellular therapeutic target for preventing nairovirus-mediated disease

Network analysis of canine brain morphometry links tumour risk to oestrogen deficiency and accelerated brain ageing.

Structural 'brain age' is a valuable but complex biomarker for several brain disorders. The dog is an unrivalled comparator for neurological disease modeling, however canine brain morphometric diversity creates computational and statistical challenges. Using a data-driven approach, we explored complex interactions between patient metadata, brain morphometry, and neurological disease. Twenty-four morphometric parameters measured from 286 canine brain magnetic resonance imaging scans were combined with clinical parameters to generate 9,438 data points. Network analysis was used to cluster patients according to their brain morphometry profiles. An 'aged-brain' profile, defined by a small brain width and volume combined with ventriculomegaly, was revealed in the Boxer breed. Key features of this profile were paralleled in neutered female dogs which, relative to un-neutered females, had an 11-fold greater risk of developing brain tumours. Boxer dog and geriatric dog groups were both enriched for brain tumour diagnoses, despite a lack of geriatric Boxers within the cohort. Our findings suggest that advanced brain ageing enhances brain tumour risk in dogs and may be influenced by oestrogen deficiency-a risk factor for dementia and brain tumours in humans. Morphometric features of brain ageing in dogs, like humans, might better predict neurological disease risk than patient chronological age
