River Recreation Management in Western States: Results of a Recreation Management Survey

This Capstone represents a qualitative analysis of survey responses concerning river recreation management policies and techniques in the Western United States. Respondents were asked about management topics including permits and fees, monitoring, enforcement, resource management, recreational experience, and current and future demand for whitewater rafting. Responses with consistent results include those for questions concerning permits for commercial uses, justification of fees, and enforcement, while responses with variation in results were received for questions concerning permits for private uses, agency self-sufficiency, monitoring, and use capacity. Most respondents do not expect a significant increased demand for commercial or private boating in the next five years. Respondents that do expect an increase do not see a need for additional commercial outfitters.

Transfer in third language phonology: Does L3 typological proximity play a role?

Les investigacions recents sobre la transferència i l'adquisició d’una L3 han indagat sobre les interferències lingüístiques quan hi ha més d'una font de transferència. Els participants en aquest estudi de cas van ser parlants d’espanyol i d’anglès, que apreninen una tercera llengua, el català, tipològicament més pròxima a l’espanyol. Aquest estudi va investigar la producció dels bilingües del català fosc /ɫ/, un segment que no és present en espanyol ja que tots els laterals es produeixen com una clara /l/, i que, tanmateix, es realitza en anglès en posició final després de vocal. Contràriament al model que planteja la proximitat d'idiomes prèviament adquirids com un dels factors determinants per a la transferència de competències, l’estudi va mostrar que la proximitat tipològica a un dels L1 no és determinista per a la transferència en el nivell fonològic en l’aprenentatge d’una L3, ja que els participants produeixen laterals catalanes similars a /ɫ/. En aquest estudi de cas es constata, d’acord amb el Model de Millora Acumulativa, com es transfereix aquest segment fonològic des de l’anglés al català.

The Contribution of Structured Activity and Deliberate Play to the Development of Expert Perceptual and Decision-Making Skill

The developmental histories of 32 players in the Australian Football League (AFL), independently classified as either expert or less skilled in their perceptual and decision- making skills, were collected through a structured interview process and their year-on-year involvement in structured and deliberate play activities retrospectively determined. Despite being drawn from the same elite level of competition, the expert decision-makers differed from the less skilled in having accrued, during their developing years, more hours of experience in structured activities of all types, in structured activities in invasion-type sports, in invasion-type deliberate play, and in invasion activities from sports other than Australian football. Accumulated hours invested in invasion-type activities differentiated between the groups, suggesting that it is the amount of invasion-type activity that is experienced and not necessarily intent (skill development or fun) or specificity that facilitates the development of perceptual and decision-making expertise in this team sport.

Play the game or get played? Researchers’ strategies around R&D policies

This chapter focuses on possible effects of current R&D policies in the scientific work, exploring some of the dilemmas they cause to researchers. In a transnational scale, R&D policies embrace performance-based research funding systems, calling for a growing accountability and a more useful and published research. Often justified by the importance of knowledge in public policies or as part of the new managerialism regime, these trends emphasize performativity on research. In this scenario, how researchers receive and interpret R&D policies is influenced according to their values and interests? Do they play the game or do they get played by it? These questions rely on a conceptual framework that conceives the research as a political scene, where researchers and R&D policies meet. Moreover, researchers’ strategies are perceived as political, considering that it is in the context of the practices that policy is interpreted and reinvented. The chapter presents an empirical study conducted in Portugal, which will be taken as an example of what Waitere et al (2011) already named as “choosing whether to resist or reinforce” R&D policies. In fact, the study revealed a strategic calculation made by researchers and the coexistence of convergent and divergent strategies concerning R&D policies. I will argue that the tensions in this strategic game are both a reflex and generator of the dilemmas of scientific work today and a sign of the complexity of public policies.

The EU and Syria – Time to Play behind Closed Doors. Jean Monnet/Robert Schuman Paper Series Special Issue, September 13, 2013

From the Introduction. Since the – presumed – utilization of chemical weapons against civilians by the Assad regime late August, the members of the Euro-Atlantic community have been building the case for a military intervention, a punishing mission against Bashar al-Assad. Despite evidences that sarin gas was used, the UK and Germany seem to be out of the race – for a similar reason: domestic politics –, leaving the US and France in the starting blocks. French President Hollande has expressed his commitment to go to war. The world is now on hold waiting for the US as President Obama, after asking US Congress to postpone a vote on a military intervention, is working on a possible diplomatic solution with Russian President Putin. Since Kerry’s comments in London earlier this week, Russian President Putin has been seeking for a diplomatic solution that would put all Syrian chemical arsenals under international supervision.

Metabolomics analysis in rats with thiamine deficiency identifies key metabolites in vulnerable brain regions and suggests neural stem progenitor cells play a role in ameliorating metabolic dysfunction

La documentation scientifique fait état de la présence, chez l’adulte, de cellules souches et progénitrices neurales (CSPN) endogènes dans les zones sous-ventriculaire et sous-granulaire du cerveau ainsi que dans le gyrus denté de l’hippocampe. De plus, un postulat selon lequel il serait également possible de retrouver ce type de cellules dans la moelle épinière et le néocortex des mammifères adultes a été énoncé. L’encéphalopathie de Wernicke, un trouble neurologique grave toutefois réversible qui entraîne un dysfonctionnement, voire une défaillance du cerveau, est causée principalement par une carence importante en thiamine (CT). Des observations récentes laissent envisager que les facteurs en cause dans la prolifération et la différenciation des CSPN pourraient également jouer un rôle important lors d’un épisode de CT. L’hypothèse, selon laquelle l’identification de nouveaux métabolites entrant dans le mécanisme ou la séquence de réactions se soldant en une CT pourraient en faciliter la compréhension, a été émise au moyen d'une démarche en cours permettant d’établir le profil des modifications métaboliques qui surviennent en de telles situations. Cette approche a été utilisée pour constater les changements métaboliques survenus au niveau du foyer cérébral dans un modèle de rats déficients en thiamine (rats DT), particulièrement au niveau du thalamus et du colliculus inférieur (CI). La greffe de CSPN a quant à elle été envisagée afin d’apporter de nouvelles informations sur la participation des CSPN lors d’un épisode de CT et de déterminer les bénéfices thérapeutiques potentiels offerts par cette intervention. Les sujets de l’étude étaient répartis en quatre groupes expérimentaux : un premier groupe constitué de rats dont la CT était induite par la pyrithiamine (rats DTiP), un deuxième groupe constitué de rats-contrôles nourris ensemble (« pair-fed control rats » ou rats PFC) ainsi que deux groupes de rats ayant subi une greffe de CSPN, soit un groupe de rats DTiP greffés et un dernier groupe constitué de rats-contrôles (rats PFC) greffés. Les échantillons de foyers cérébraux (thalamus et CI) des quatre groupes de rats ont été prélevés et soumis à des analyses métabolomiques non ciblées ainsi qu’à une analyse visuelle par microscopie à balayage électronique (SEM). Une variété de métabolites-clés a été observée chez les groupes de rats déficients en thiamine (rats DTiP) en plus de plusieurs métabolites dont la documentation ne faisait pas mention. On a notamment constaté la présence d’acides biliaires, d’acide cynurénique et d’acide 1,9— diméthylurique dans le thalamus, alors que la présence de taurine et de carnosine a été observée dans le colliculus inférieur. L’étude a de plus démontré une possible implication des CSPN endogènes dans les foyers cérébraux du thalamus et du colliculus inférieur en identifiant les métabolites-clés ciblant les CSPN. Enfin, les analyses par SEM ont montré une amélioration notable des tissus à la suite de la greffe de CSPN. Ces constatations suggèrent que l’utilisation de CSPN pourrait s’avérer une avenue thérapeutique intéressante pour soulager la dégénérescence symptomatique liée à une grave carence en thiamine chez l’humain.

Implementation of the Macroeconomic Adjustment Programmes in the Euro Area: State-of-Play. CEPS E-Book, 11 March 2014

Two of the four macroeconomic adjustment programmes – in Portugal and Ireland – can be considered a success in the sense that the initial expectations in terms of adjustment, both fiscal and external, were broadly fulfilled. A rebound based on exports has taken hold in these two countries, but a full recovery will take years. In Greece the initial plans were insufficient. While the strong impact of the fiscal adjustment on demand could have been partially anticipated at the time, the resistance to structural reforms was more surprising and remains difficult to cure. The fiscal adjustment is now almost completed, but the external adjustment has not proceeded well. Exports are stagnating despite impressive falls in wage costs. In Cyprus, the outcome has so far been less severe than initially feared. It is still too early to find robust evidence in any country that the programmes have increased the long-term growth potential. Survey-based evidence suggests that structural reforms have not yet taken hold. The EU-led macroeconomic adjustment programmes outside the euro area (e.g. Latvia) seem to have been much stricter, but the adjustment was quicker and followed by a stronger rebound.
