Understanding insertion and integration in a study abroad context: the case of English-speaking sojourners in France

This paper draws on a recent study of British students of languages undertaking a year abroad in France, in a variety of placements (as language teaching assistants, as exchange students, and as workplace interns). The data were gathered in the context of the 2011-2013 LANGSNAP project, a larger study undertaken which investigated both the language learning and social integration of British students spending an academic year abroad in France, Spain or Mexico Having made a positive choice to specialise in languages at university, and having already reached a relatively advanced level in French during their secondary school education, it could be assumed that these students were positively motivated to further develop their language skills, to deepen their intercultural understanding, and to integrate socially within the local society. Indeed, in pre-departure interviews (in French), the participating students unanimously expressed the wish to integrate and in particular to make French same-aged friends. The paper first of all presents an overview of the range of tools used to gather both quantitative and qualitative data on participants’ social integration. The paper then goes on to evaluate the degree of success of even such highly motivated participants in achieving this declared goal, and to consider social, sociolinguistic and personal factors which appear to influence the degree of social integration achieved by individual participants

Exchange rate regimes and monetary autonomy: Empirical evidence from selected Caribbean countries

This paper uses the error correcting methodology to investigate how pegged and non-pegged exchange rate regimes in a set of Caribbean countries affect the closeness of the relationship between changes in a base country rate and the local rate. This interest rate parity condition is subjected to effects arising from capital controls and common shocks related to inflation and external debt. The results support the standard theory that peg countries (like Barbados) follow the base country interest rate more closely than the managed float or flexible rate economies (such as Trinidad and Tobago and Jamaica). In addition, the paper supports the open economy macroeconomic policy trilemma proposition that only two of the following goals – stability in the exchange rate, national independence in monetary policy and free capital mobility- can be achieved simultaneously.Exchange rates, Monetary policy, Error correcting mechanisms

Relationships Between Crime and Tourism

This paper presents a general overview of the relationships between crime and tourism. Literature on crime and tourism is reviewed and elaborated to indicate the unexplored complexity of the relationships that exist to identify areas of potential research. Difficulties in defining crime are noted and the importance of appreciating the context of tourism in any understanding of tourist area crime is emphasized. Topics discussed include tourists as victims of crime, reducing crime against tourists and crime as an attraction. The great potential and need for future research in the area is highlighted. The paper concludes by introducing the remaining articles in this issue

The Long Wavelength Array Software Library

The Long Wavelength Array Software Library (LSL) is a Python module that provides a collection of utilities to analyze and export data collected at the first station of the Long Wavelength Array, LWA1. Due to the nature of the data format and large-N ($\gtrsim$100 inputs) challenges faced by the LWA, currently available software packages are not suited to process the data. Using tools provided by LSL, observers can read in the raw LWA1 data, synthesize a filter bank, and apply incoherent de-dispersion to the data. The extensible nature of LSL also makes it an ideal tool for building data analysis pipelines and applying the methods to other low frequency arrays.Comment: accepted to the Journal of Astronomical Instrumentation; 24 pages, 4 figure

GENETIC DIVERSITY AND GENE FLOW IN THE MORPHOLOGICALLY VARIABLE, RARE ENDEMICS BEGONIA DREGEI AND BEGONIA HOMONYMA (BEGONIACEAE)

Begonia dregei and B. homonyma (Begoniaceae), rare plants endemic to coastal forests of eastern South Africa, are two closely related species with high levels of variation among populations in the shape of leaves. Distribution of genetic variation and genetic relatedness were investigated in 12 populations of B. dregei and seven of B. homonyma using polyacrylamide gel electrophoresis. Twelve of the 15 enzyme loci examined were polymorphic, but only seven loci were polymorphic within at least one population. Genetic diversity measures indicated that the among-population gene differentiation represents >90% of the total genetic component in both species considered individually or combined. This indicated restricted gene flow, consistent with the limited dispersal abilities of Begonia generally and the ancient separation of isolated forest patches. Genetic distances among populations are much higher than usually found within species. Allozyme data provide no support for the recognition of B. dregei and B. homonyma as distinct species.Excellent models for the study of evolutionary pro¬cesses are often provided by taxa that pose the greatest problems in systematics (Wolf, Soltis, and Soltis, 1991). Endemic plants provide a superb tool for studying the dynamic processes of speciation and evolution, particu¬larly island endemic plants (Ito and Ono, 1990; Aradya, Mueller-Dombois, and Ranker, 1991; Barrett, 1996). Ev¬idence of most evolutionary events that formed continen¬tal biota has been lost because such biota are so ancient (Carson, 1987). Complex patterns of variation may blur species boundaries and lead to taxonomic complexity

Detecting Invasive Insects with Unmanned Aerial Vehicles

A key aspect to controlling and reducing the effects invasive insect species have on agriculture is to obtain knowledge about the migration patterns of these species. Current state-of-the-art methods of studying these migration patterns involve a mark-release-recapture technique, in which insects are released after being marked and researchers attempt to recapture them later. However, this approach involves a human researcher manually searching for these insects in large fields and results in very low recapture rates. In this paper, we propose an automated system for detecting released insects using an unmanned aerial vehicle. This system utilizes ultraviolet lighting technology, digital cameras, and lightweight computer vision algorithms to more quickly and accurately detect insects compared to the current state of the art. The efficiency and accuracy that this system provides will allow for a more comprehensive understanding of invasive insect species migration patterns. Our experimental results demonstrate that our system can detect real target insects in field conditions with high precision and recall rates.Comment: IEEE ICRA 2019. 7 page

Placement type and language learning during residence abroad

The “year abroad” is a longstanding component of British university degree programmes in languages. As noted by other commentators (Coleman, 1997 and this volume; Collentine, 2009), the British “year abroad” is typically undertaken by language majors with several years’ prior language study and a relatively advanced proficiency level in their target language(s). It is a common requirement for programme completion, to spend two academic semesters abroad. However students can have considerable latitude in how the time abroad is spent, and assessment by the home institution is relatively “light touch”, typically involving e.g. a substantial project or long essay. Today, languages students typically undertake one of three placement types: as English language teaching assistants, on other forms of work placement, or as Erasmus exchange students following relevant academic programmes at a partner university. Numbers of U.K. languages students undertaking the classic university student exchange version of the year abroad are relatively stable at around 7,500 per year, a much smaller number than incoming international students at U.K. universities, though numbers undertaking teaching assistantships and other work placements have risen (British Academy & University Council for Modern Languages, 2012; King, Findlay, & Ahrens, 2010). The linguistic benefits of the year abroad have been tracked in various research studies (Coleman, 1996, 1997; Ife, 2000; Klapper & Rees, 2012; Meara, 1994; Willis, Doble, Sankarayya, & Smithers, 1977). In general, this research indicates that while learners make considerable progress in their target L2, the variability which is characteristic of residence abroad programmes more widely (Kinginger, 2008) affects this group as well (on this see especially Klapper & Rees, 2012). The research project “Social Networks, Target Language Interaction and Second Language Acquisition During the Year Abroad: A longitudinal study“ (the LANGSNAP project: http://langsnap.soton.ac.uk) was planned to provide fuller evidence on L2 acquisition during the year abroad, including documenting development on a range of language domains, and connecting progress in L2 to a range of individual, social and contextual variables. (See Mitchell, 2014 for an overview.)The project tracked a cohort of 56 students majoring in French or Spanish, before, during and after spending their year abroad in France, Spain or Mexico during the academic year 2011-12.This chapter reports one aspect of the findings of this project: the experience of the French L2 participants (N=29) of different placement types in France, and how placement type related to aspects of their target language developmen

Internet visibility and cyberbullying: A survey of Cape Town high school students

The pervasive and open nature of the Internet in the everyday lives of South African children has facilitated benefits such as increased collaboration,learning opportunities and access to knowledge (A2K). However, the online environment’s increased visibility has at the same time provided new ways for children to bully each other, and the evidence in the available literature suggests that online bullying – “cyberbullying” – may result in more harmful consequences than offline variants of such behaviour. This article provides findings from an online survey of cyberbullying experiences among a sample of high school students aged 15 to 21 years in the city of Cape Town. The survey found clear evidence of cyberbullying, as reported by both victims and perpetrators, and it was found that social networking sites (SNSs) were the online spaces most-used for cyberbullying, followed by short message service (SMS) platforms. Among perpetrators, 19% reported that they cyberbullied once or twice a week and 10% said they cyberbullied every day or almost every day. The survey also uncovered gender differences in the length of time it took for victims of cyberbullying to put the incidents behind them, with more females than males taking a long time (i.e., a few weeks, or a month or two or more) to stop feeling “bothered” by the incident. The authors conclude that the findings show a need for improved efforts, in schools and in student households, towards building learners’,parents’ and teachers’ e-safety awareness and capacity for preventative action

Influence of season and method of topkill on resprouting characteristics and biomass of Quercus nigra saplings from a southeastern U.S. pine-grassland ecosystem

© 2014, Springer Science+Business Media Dordrecht. The resprouting ability of woody plants in frequently burned ecosystems may be influenced by the season and method of topkill. We conducted an experiment to test for the effects of season and method of topkill on aboveground biomass, belowground biomass, and mortality of hardwoods found in a southeastern U.S. pine-grassland. We predicted that topkill occurring during the growing season and topkill by fire would have greater negative impacts on resprouting and root growth and result in greater mortality. We conducted a shadehouse experiment in north Florida in which we applied topkill treatments (burn, clip, and no-topkill) in three seasons (dormant, early growing, and mid growing) to Quercus nigra (water oak) saplings. Plants were destructively sampled 12 months post-treatment to measure aboveground and belowground biomass. Saplings topkilled in the early and mid growing seasons had reduced growth and greater mortality one-year post-treatment compared to plants topkilled in the dormant season. While there was no difference in one-year post-treatment biomass or mortality of saplings between the two methods of topkill, clipped plants had more stems and shorter average stem height than plants topkilled by fire. Root growth continued despite topkilling for all seasons and was greatest for no-topkill plants. These results suggest that while topkill reduces biomass, hardwoods have evolved to maintain belowground biomass reserves, enabling genets to resprout following subsequent topkilling and to persist through frequent disturbances
