Developed countries, led by the EU and the US, have consistently called for ‘deeper integration’ over the course of the past three decades i.e., the convergence of ‘behind-the-border’ or domestic polices and rules such as services, competition, public procurement, intellectual property (“IP”) and so forth. Following the collapse of the Doha Development Round, the EU and the US have pursued this push for deeper integration by entering into deep and comprehensive free trade agreements (“DCFTAs”) that are comprehensive insofar as they are not limited to tariffs but extend to regulatory trade barriers. More recently, the EU and the US launched negotiations on a Transatlantic Trade and Investment Partnership (“TTIP”) and a Trade in Services Agreement (“TISA”), which put tackling barriers resulting from divergences in domestic regulation in the area of services at the very top of the agenda. Should these agreements come to pass, they may well set the template for the rules of international trade and define the core features of domestic services market regulation. This article examines the regulatory disciplines in the area of services included in existing EU and US DCFTAs from a comparative perspective in order to delineate possible similarities and divergences and assess the extent to which these DCFTAs can shed some light into the possible outcome and limitations of future trade negotiations in services. It also discusses the potential impact of such negotiations on developing countries and, more generally, on the multilateral process.

RATIONALE: Risk of infection with Pseudomonas aeruginosa in cystic fibrosis (CF) may be associated with environmental factors.
OBJECTIVES: To determine whether residential location is associated with risk of first acquisition of P. aeruginosa.
METHODS: We performed bronchoalveolar lavage and upper airway cultures in children newly diagnosed with CF to identify infection with P. aeruginosa during infancy and early childhood. Children were assessed according to their residence in a regional or metropolitan area. Multilocus sequence typing was used to determine P. aeruginosa genotype. An environmental questionnaire was also administered.
MEASUREMENTS AND MAIN RESULTS: A total of 105 of 120 (87.5%) infants diagnosed with CF were included in this study. Diagnosis in 65 infants (61.9%) followed newborn screening at mean age of 4.6 weeks. Sixty subjects (57.1%) were homozygous ΔF508, and 47 (44.8%) were female. Fifty-five (52.3%) infants were regional, of whom 26 (47.3%), compared with 9 of 50 (18.0%) metropolitan children, acquired infection with P. aeruginosa (odds ratio, 4.084; 95% confidence interval, 1.55-11.30). Age at acquisition was similar (regional: median, 2.31 yr; range, 0.27-5.96 yr; metropolitan: median, 3.10 yr, range, 0.89-3.70 yr). Strain typing identified P. aeruginosa genotypes often encountered in different ecological settings and little evidence of cross-infection. Ninety questionnaires (85.7%) were completed. Those who acquired P. aeruginosa were more likely to be living in a household that used water sprinkler systems (P = 0.032), but no differences were identified to explain increased risk of acquisition of P. aeruginosa in regional children.
CONCLUSIONS: Geographical difference in residence of children with CF was associated with increased risk of first acquisition of P. aeruginosa, usually with strains associated with the environment rather than with cross-infection.

The EU has historically been portrayed as a distinctive international actor both in terms of the norms and values it exports in context of its international relations and the manner in which it seeks to influence others. However, such claims to the EU’s distinctiveness are increasingly being questioned. This article joins this chorus of voices arguing the non-distinctiveness of the EU’s foreign policy power by focusing on a specific feature of the EU’s external trade policy, the role of World Trade Organization (WTO) dispute settlement in the EU’s attempts to promote its interests, values and norms.

Providing the first comprehensive examination of the key regulatory disciplines included in the new generation of EU free trade agreements (FTAs), this book investigates the EU's supposed deep trade agenda through a legal analysis of these FTAs. In doing so, Billy A. Melo Araujo determines whether there is any substance behind the EU's foreign policy rhetoric regarding the need to introduce regulatory issues within the remit of international trade law.
At a time when the EU is busily negotiating so-called 'mega-FTAs', such as the Transatlantic Trade and Investment Partnership (TTIP) and the plurilateral Trade in Services Agreement (TISA), Melo Araujo offers a timely insight into the important questions raised by such FTAs, in particular concerning the future of the multilateral trade system, the loss of policy autonomy, and the democratic legitimacy of regulating through treaty-making. The book provides a detailed analysis of the regulatory disciplines included in the more recent EU FTAs and explores the possible implications of such disciplines. Offering a significant contribution to a wider debate, this is a must read for those interested in the legal dimension of the EU's deep trade agenda.

WHIRLBOB, also known as STRIBOBr2, is an AEAD (Authenticated Encryption with Associated Data) algorithm derived from STRIBOBr1 and the Whirlpool hash algorithm. WHIRLBOB/STRIBOBr2 is a second round candidate in the CAESAR competition. As with STRIBOBr1, the reduced-size Sponge design has a strong provable security link with a standardized hash algorithm. The new design utilizes only the LPS or ρ component of Whirlpool in flexibly domain-separated BLNK Sponge mode. The number of rounds is increased from 10 to 12 as a countermeasure against Rebound Distinguishing attacks. The 8 ×8 - bit S-Box used by Whirlpool and WHIRLBOB is constructed from 4 ×4 - bit “MiniBoxes”. We report on fast constant-time Intel SSSE3 and ARM NEON SIMD WHIRLBOB implementations that keep full miniboxes in registers and access them via SIMD shuffles. This is an efficient countermeasure against AES-style cache timing side-channel attacks. Another main advantage of WHIRLBOB over STRIBOBr1 (and most other AEADs) is its greatly reduced implementation footprint on lightweight platforms. On many lower-end microcontrollers the total software footprint of π+BLNK = WHIRLBOB AEAD is less than half a kilobyte. We also report an FPGA implementation that requires 4,946 logic units for a single round of WHIRLBOB, which compares favorably to 7,972 required for Keccak / Keyak on the same target platform. The relatively small S-Box gate count also enables efficient 64-bit bitsliced straight-line implementations. We finally present some discussion and analysis on the relationships between WHIRLBOB, Whirlpool, the Russian GOST Streebog hash, and the recent draft Russian Encryption Standard Kuznyechik.

Educational leadership is challenging, complex, and vitally important to student success. Despite the publication of theories, books, and research on school leadership, a perception of a chasm between theory and practice exists. However, the intentional consideration and implementation of theory can make an enormous impact on practice. This is revealed in this dissertation through the exploration of invitational leadership theory through an autoethnographic study of my leadership journey, as well as the intentionally inviting leadership of Billy Tate, a veteran school principal in Belfast, Northern Ireland. This dissertation uses an amalgamated methodology of interview and observational research embedded within an autoethnography to intimately explore invitational theory in practice through the lens of a new school principal in Southern Ontario and a veteran principal in Belfast. This study provides an intimate understanding of the impact and applicability of invitational educational leadership theory in two unique educational, political, and social contexts and draws conclusions from the consideration of and reflection upon my leadership and Billy Tate’s. This dissertation reveals invitational leadership as a theory of practice that has significantly influenced two very different school leaders and posits that invitational theory is a theory of practice worthy of consideration by educational leaders from around the world.

In challenging normative social relations, queer cultural studies has shied away from deploying historical materialist theoretical tools. My research addresses this gap by drawing these two literatures into conversation. I do so by investigating how global economic relations provide an allegorical and material context for the regulation, representation and re-imagining of working-class queer childhood through anti- capitalist queer readings of three films: Kes, Billy Elliot, and Boys Village. I deploy this reading practice to investigate how these films represent heteronormative capitalism’s systematic extermination of the life possibilities of working class children, how children resist forces of normalisation by creating queer times and spaces, and how nostalgia engenders a spatio-temporal understanding of queerness through a radical utopianism. My analysis foregrounds visual cultural productions as sites for understanding how contemporary social worlds exclude queer working class children, who struggle to insert themselves into and thereby shift the grounds of normative social relations.

La communication cellulaire est un phénomène important pour le maintien de l’homéostasie des cellules. Au court des dernières années, cette sphère de recherche sur la signalisation cellulaire a connue des avancées importantes au niveau de l’identification des acteurs principaux impliqués dans la reconnaissance extracellulaire des signaux, ainsi que la compréhension des voies de signalisation engagées par les cellules pour répondre aux facteurs extracellulaires. Malgré ces nouvelles informations, les diverses interrelations moléculaires entre les acteurs ainsi que les voies de signalisation cellulaire, demeurent mal comprises. Le transfert d’énergie de résonance de bioluminescence (BRET) permet la mesure d’interactions protéiques et peut être utilisé dans deux configurations, le BRET480-YFP (connu aussi comme le BRET1) et le BRET400-GFP (connu aussi en tant que BRET2). Suite à l’oxydation de son substrat, la luciférase de renilla peut transférer son énergie à une protéine fluorescente, uniquement si elles sont à proximité l’une de l’autre (≤100Å). La combinaison dans un seul essai des BRET480-YFP et BRET400-GFP, a permis de suivre trois paires d’interactions, sur une même population cellulaire. Par contre, l’utilisation de deux substrats pour la réaction de bioluminescence rend impossible la mesure simultanée des différents signaux de BRET, pour ce trois nouvelles configurations de BRET ont été mises au point en utilisant des nouvelles protéines fluorescentes. Ainsi deux des nouvelles couleurs de BRET ayant des émissions résolues, le BRET400-BFP et le BRET400mAmetrine ont pu être combinées pour mesurer l’engagement par un RCPG d’une protéine G, ainsi que l’accumulation du second messager. La combinaison de ces BRET a également permis de révéler la formation d’un complexe entre le récepteur α2A adrénergique (α2AAR), Gαi1, le dimère Gβγ ainsi que la kinase des récepteurs couplés aux protéines G (GRK2), suite à l’activation du récepteur. De plus, seule l’entrée de GRK2 semble être en mesure de causer la désensibilisation du α2AAR, en s’intercalant entre Gαi1 et Gβγ. Par contre, la stabilisation de l’interaction entre α2AAR et la β-arrestine2 semble nécessiter l’activité kinase de GRK2. Une autre étude a révélé l’importance de différentes Gα pour la mobilisation du calcium, suite à l’activation du récepteur aux opioïdes de type delta (DOR). Suite à la surexpression de Gα de la famille Gαq, il a été possible de mesurer une influence de ces Gα sur la mobilisation du calcium. Toutefois, cette réponse calcique mesurée en présence des Gαq demeure sensible aux prétraitements à la toxine de Bordetella pertussis, qui inhibe sélectivement l’activité des Gαi. De plus, la co-expression de Gαi et Gαq permet de potentialiser la mobilisation de calcium, démontrant une interrelation entre ces deux familles de protéine Gα, pour la signalisation du DOR. Afin de démontrer l’interrelation directe, des expériences de BRET ont été réalisées entre différentes Gα. En plus de montrer la formation de complexes sélectifs entre les Gα, les expériences de BRET réalisées en parallèle d’analyses de séquences de Gα, ont également mis à jour un site de sélectivité d’interaction entre les Gα, l’hélice α4. Suite à la transposition de cette hélice α4 de Gα12 sur Gαi1, qui normalement n’interagissent pas, il a été possible de forcer l’interaction entre Gα12 et Gαi1, confirmant ainsi que cette hélice α contient l’information permettant une sélectivité d’interaction. Au cours de cette thèse, il a été possible de générer de nouvelles méthodes de mesure d’interactions protéiques qui permettent de multiplexer différents signaux, ce qui a permis de mettre à jour de nouvelles interactions entre divers effecteurs de la signalisation de RCGP
