A gravity model analysis of trade and direct investment in the Central and Eastern European Countries

The opening up process of the central and eastern European (CEE) countries marked new beginnings in terms of greater integration of trade and foreign direct investment (FDI) with Western Europe. Adopting a two-stage out-of-sample gravity equation approach to predicting East West trade patterns, a panel data set of bilateral exports from twelve EU countries to twenty OECD partner countries is estimated over the 1992-2003 period to examine how integrated the CEE countries are with the West European countries. In general, countries which are initially less well-integrated with the EU have strongest trade potential: among the EU accession countries, the potential candidate countries look set to benefit most whereas the mixed trade ratios among the EU associated countries reflect very diverse economic structures. Using a similar approach to project East West FDI patterns, the potential to actual ratios of FDI stocks indicate a very uneven distribution of FDI among the eleven CEE countries. The FDI stock ratios accord with patterns of regional specialisation for the Czech Republic, Hungary and Poland and suggest greatest FDI potential lies with the two latest accession countries. As the West European countries represents the CEE countries main trading partners and their main sources of FDI, the nature of the trade-direct investment relation among the group of EU OECD countries is of potential importance to the CEE countries. Merging the determinants for both trade and FDI into one model and estimating the merged model as a trade equation and as an FDI equation, the EU OECD patterns of FDI are characterised by both horizontal FDI (HFDI) and vertical FDI (VFDI). The dual role of HFDI and VFDI is supported when the general model of trade and FDI determinants is estimated using an instrumental variables method and when the additional price variables of FDI and trade are interpreted as cross-price elasticity effects. In a competitive world, attracting more FDI to the CEE countries may not only mean catering to the traditional MNE motives, but can also depend on transition-related factors and host country policies. Using a panel data set of bilateral FDI flows from twelve EU countries to eleven CEE countries, the traditional determinants of direct investment along with the liberalisation process and infrastructure endowments are found to significantly affect FDI over the 1994-2003 period

A gravity model of remittance determinants: evidence from Latin America and the Caribbean

A gravity model of remittance determinants: evidence from Latin America and the Caribbean. Regional Studies. This paper constructs a microeconomic model of the motivation for remittances and uses it to explore the macroeconomic determinants. In addition, a new measure of bilateral remittances is used to estimate a gravity model of remittances for 27 Latin American and Caribbean countries and 18 industrialized countries. The results suggest remittances are motivated by a combination of altruism and self-interest, both of which are encapsulated by economic and non-economic variables

Development and formative evaluation of patient research partner involvement in a multi-disciplinary European translational research project

Patient and public involvement (PPI) improves the quality of health research and ensures that research is relevant to patients’ needs. Though PPI is increasingly evident in clinical and health services research, there are few examples in the research literature of effective PPI in translational and laboratory-based research. In this paper, we describe the development and evaluation of PPI in a multi-centre European project (EuroTEAM – Towards Early biomarkers in Arthritis Management) that included both translational and laboratory-based and psychosocial research. We found that although most PPI in EuroTEAM was centred around the psychosocial research, there were examples of PPI in the laboratory studies. As the project evolved, researchers became better at accommodating PPI and identifying PPI opportunities. It was generally agreed that PPI had a positive impact on the project overall, particularly on public engagement with the research. We concluded that the inclusion of both psychosocial and laboratory-based research in the same project facilitated PPI across all aspects of the research. In future projects, we would try to specify individual PPI activities in more detail at the project-planning stage, and better accommodate patient partners who are not native speakers of English. Background Patient and public involvement (PPI) enhances research quality and relevance and is central to contemporary health policy. The value of PPI has been recognised in rheumatology research, though there are limited examples of PPI in basic and translational science. The EU FP7 funded ‘EuroTEAM’ (Towards Early biomarkers in Arthritis Management) project was established to develop biomarker-based approaches to predict the future development of rheumatoid arthritis and incorporated psychosocial research to investigate the perceptions of ‘at risk’ individuals about predictive testing, and to develop informational resources about rheumatoid arthritis (RA) risk. Patient involvement was central to EuroTEAM from the inception of the project. The objective of this paper is to describe the development of PPI in EuroTEAM, formatively assess the impact of PPI from the perspectives of researchers and patient research partners (PRPs), reflect on successes and lessons learned, and formulate recommendations to guide future projects. Methods Two mixed-methods surveys (for PRPs and researchers) and a teleconference were undertaken to assess the impact of PPI on individual work packages and on EuroTEAM overall. Results There was consensus about the positive impact of PPI on the research and on the experiences of those involved. In particular, the positive impact of PPI on the personal development of researchers, and on effective public engagement with EuroTEAM research were highlighted. Researchers described adapting their practice in future projects to facilitate PPI. Spin-off projects and ongoing collaborations between PRPs and researchers reflected the value of PPI to participants. PPI was more frequently integrated in psychosocial research, though examples of PPI in laboratory/translational science were also described. PRPs asked for more opportunities to contribute meaningfully to basic scientific research and for more extensive feedback on their contributions. Conclusions The findings were used to formulate recommendations to guide effective involvement of patients in future similar projects, including identifying specific training requirements for PRPs and researchers, the identification of PRP focused tasks/deliverables at the project planning stage, and supporting access to involvement for all PRPs. Importantly, the distinctive multidisciplinary approach of EuroTEAM, incorporating both basic science and psychosocial research, facilitated patient involvement in the project overall

Emotional competence and help-seeking intentions as predictors of educational success in vocational training students

Given the high prevalence of psychological distress among vocational training (VT) students, this study aimed to assess the role of interpersonal emotional competence as a resilience factor promoting the educational success of this population. We postulated that emotional competence would promote educational success, both directly and indirectly by fostering students’ help-seeking intentions when facing a personal or school-related problem. To test these hypotheses, we used a sample of 219 VT students from the Canadian province of Quebec (68% women, Mage = 24.58; SDage = 7.95) enrolled in various programs (e.g. institutional and home care assistance, welding and fitting, secretarial studies, and professional cooking). These students were assessed two times, during the first half of their training and again after their training. Results from structural equation modelling revealed that emotional competence was a positive predictor of help-seeking intentions and educational success. However, having the intention to seek help did not translate into higher levels of educational success. Overall, these results highlight the importance of supporting VT students in the development and strengthening of their emotional competence to promote their educational success. Future research is needed to further understand the help-seeking process among VT students and its implications for their academic outcomes. -- Keywords : adult learning ; emotional intelligence ; help seeking behavior ; social emotional competence ; vocational education

Evidence for plunging river plume deposits in the Pahrump Hills member of the Murray formation, Gale crater, Mars

Recent robotic missions to Mars have offered new insights into the extent, diversity and habitability of the Martian sedimentary rock record. Since the Curiosity rover landed in Gale crater in August 2012, the Mars Science Laboratory Science Team has explored the origins and habitability of ancient fluvial, deltaic, lacustrine and aeolian deposits preserved within the crater. This study describes the sedimentology of a ca 13 m thick succession named the Pahrump Hills member of the Murray formation, the first thick fine‐grained deposit discovered in situ on Mars. This work evaluates the depositional processes responsible for its formation and reconstructs its palaeoenvironmental setting. The Pahrump Hills succession can be sub‐divided into four distinct sedimentary facies: (i) thinly laminated mudstone; (ii) low‐angle cross‐stratified mudstone; (iii) cross‐stratified sandstone; and (iv) thickly laminated mudstone–sandstone. The very fine grain size of the mudstone facies and abundant millimetre‐scale and sub‐millimetre‐scale laminations exhibiting quasi‐uniform thickness throughout the Pahrump Hills succession are most consistent with lacustrine deposition. Low‐angle geometric discordances in the mudstone facies are interpreted as ‘scour and drape’ structures and suggest the action of currents, such as those associated with hyperpycnal river‐generated plumes plunging into a lake. Observation of an overall upward coarsening in grain size and thickening of laminae throughout the Pahrump Hills succession is consistent with deposition from basinward progradation of a fluvial‐deltaic system derived from the northern crater rim into the Gale crater lake. Palaeohydraulic modelling constrains the salinity of the ancient lake in Gale crater: assuming river sediment concentrations typical of floods on Earth, plunging river plumes and sedimentary structures like those observed at Pahrump Hills would have required lake densities near freshwater to form. The depositional model for the Pahrump Hills member presented here implies the presence of an ancient sustained, habitable freshwater lake in Gale crater for at least ca 10^3 to 10^7 Earth years

Sugar trade and the role of historical colonial linkages

Past colonialism has shaped current policies and patterns relating to sugar trade. To examine the effects of historical colonial linkages on sugar trade, the gravity model is estimated for a panel of raw sugar imports into 25 OECD countries from the rest of the world over the 1961-2016 period. Colonial linkages in a North-South direction increase sugar trade, but colonial linkages in a North-North direction decrease it. Several distinct North-South colonial channels are identified. Sugar trade is enhanced by the major empire shipping routes, rail infrastructure, cultural proximity and preferential market access

Crop pests and predators exhibit inconsistent responses to surrounding landscape composition

The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are measured. Here, we use a pest-control database encompassing 132 studies and 6,759 sites worldwide to model natural enemy and pest abundances, predation rates, and crop damage as a function of landscape composition. Our results showed that although landscape composition explained significant variation within studies, pest and enemy abundances, predation rates, crop damage, and yields each exhibited different responses across studies, sometimes increasing and sometimes decreasing in landscapes with more noncrop habitat but overall showing no consistent trend. Thus, models that used landscape-composition variables to predict pest-control dynamics demonstrated little potential to explain variation across studies, though prediction did improve when comparing studies with similar crop and landscape features. Overall, our work shows that surrounding noncrop habitat does not consistently improve pest management, meaning habitat conservation may bolster production in some systems and depress yields in others. Future efforts to develop tools that inform farmers when habitat conservation truly represents a win–win would benefit from increased understanding of how landscape effects are modulated by local farm management and the biology of pests and their enemies
