Populist radical right parties have become major political actors in Europe. This paper analyses the path and the different phases that have led them from the fringes of public debate to their present signifi cance, which is based on their capacity to attract electoral support and infl uence the political agendas in their respective countries. Besides, an analysis of the core ideological beliefs of these parties, and of the topics on which their mobilization capacity rests, is provided, as well as of the type of voters that are attracted by them. Finally, the authors discuss the meaning and impact of the growing popularity of the ideas and proposals put forward by the populist radical right parties.

The issue of this thesis concerns a selection of historical debates in which new Swedish drama is under discussion. The studied debates take place in the cultural and political fields and within the fields of theater and literature and deal with a recurring assumption in Swedish theatre history – that new Swedish drama is insufficient. The primary object of this thesis is to find explanations to: why is the Swedish new drama so often described as defective? The following questions, guiding the analysis, are: How are the crises described? What are the stakes? How has the dramatic text been influenced by being judged either as literary product or a product for the stage? How is the playwright’s role described, and perhaps changed, in the crises? The aim of the analysis is to understand how traditions and conventions are shaping the debates and contribute to perpetrate the myth of the malfunctioning Swedish new play. In a historical perspective several attempts have been made to govern new Swedish drama by legislative and political power. New Swedish drama has, for example, been viewed as a possible expression of the nation, as part of shaping the Swedish Welfare state or creating interactive communication with the audience. Despite its many uses, new Swedish drama continues to be describes as flawed. The study starts with King Gustav III:s Swedish theatre where the purpose was to produce Swedish original plays. The study ends with an analysis of a new government grant for new Swedish drama, which was installed in 1999. The chosen debates are analyzed with the help of concepts borrowed from the French sociologist Pierre Bourdieu, looking at each historical situation as a possible moment for the establishment of the field ”new Swedish drama”. The survey ends with eight interviews with playwrights, who are active today. The conditions for the new Swedish drama are the guiding line in this thesis. These conditions are found in the cultural, social and historical contexts that cooperate when a taste or convention is being shaped. They are part of the discourses in the field, where criteria for the new Swedish drama is formulated. In order to understand the significance of, for example, the expression, ”the newly written Swedish drama” research has been pursued in biographical material, historical surveys, and debates in the daily press and in professional journals. Without being a full bourdieuan analysis, the thesis is using concepts from Bourdieu. The work of British feminist theatre historian Tracy C Davis inspires the critical historic perspective.

Il progetto Sicily in Transition è nato dalla collaborazione delle Università di York e di Roma Tor Vergata, con il pieno ap-poggio della Soprintendenza ai BB. CC. AA di Palermo. La finalità della nostra ricerca è quella di analizzare, attraverso il registro archeologico, in quale modo i mutamenti di regime politico hanno influenzato organizzazione, composizione e stili di vita delle popolazioni soggette. L’arco di tempo considerato va dal VI al XIII secolo, periodo nel quale la Sicilia ha visto diverse dominazioni: quella bizantina, islamica, normanna e sveva. Sicily in Transition prevede di analizzare con metodi in parte nuovi, in parte più tradizionali, sia insiemi di reperti (ecofatti e manufatti) prodotti da precedenti scavi, sia di acquisire dati attraverso nuove indagini. In particolare gli scriventi hanno scelto di indagare un’area molto promettente della Sicilia centrale: il territorio di Castronovo di Sicilia. Qui, in due campagne di ricerca durate ciascuna quattro settimane, sono state realizzate indagini magnetometriche, ricognizioni di superficie, di archeologia dell’architettura e sondaggi stratigrafici. La finalità era quella di valutare il potenziale archeologico dei principali siti storici del territorio. I primi risultati sono promettenti in relazione alla varietà tipologica e cronologica dei diversi insediamenti identificati: una fortezza dei secoli VII-IX sul Monte Kassar; un fortilizio con fasi del pieno medioevo e dell’età moderna sul Colle San Vitale; un ampio villaggio non difeso con fasi dall’età tardoantica al medioevo, incluse importanti testimonianze di età islamica, nell’area del Casale San Pietro. Le indagini preliminari hanno quindi confermato le ampie potenzialità informative dell’intero territorio di Castronovo rispetto ai temi della nostra ricerca e stanno quindi consentendo di programmare gli interventi futuri.

Since years, research on SnRK1, the major cellular energy sensor in plants, has tried to define its role in energy signalling. However, these attempts were notoriously hampered by the lethality of a complete knockout of SnRK1. Therefore, we generated an inducible amiRNA::SnRK1α2 in a snrk1α1 knock out background (snrk1α1/α2) to abolish SnRK1 activity to understand major systemic functions of SnRK1 signalling under energy deprivation triggered by extended night treatment. We analysed the in vivo phosphoproteome, proteome and metabolome and found that activation of SnRK1 is essential for repression of high energy demanding cell processes such as protein synthesis. The most abundant effect was the constitutively high phosphorylation of ribosomal protein S6 (RPS6) in the snrk1α1/α2 mutant. RPS6 is a major target of TOR signalling and its phosphorylation correlates with translation. Further evidence for an antagonistic SnRK1 and TOR crosstalk comparable to the animal system was demonstrated by the in vivo interaction of SnRK1α1 and RAPTOR1B in the cytosol and by phosphorylation of RAPTOR1B by SnRK1α1 in kinase assays. Moreover, changed levels of phosphorylation states of several chloroplastic proteins in the snrk1α1/α2 mutant indicated an unexpected link to regulation of photosynthesis, the main energy source in plants.

Many existing encrypted Internet protocols leak information through packet sizes and timing. Though seemingly innocuous, prior work has shown that such leakage can be used to recover part or all of the plaintext being encrypted. The prevalence of encrypted protocols as the underpinning of such critical services as e-commerce, remote login, and anonymity networks and the increasing feasibility of attacks on these services represent a considerable risk to communications security. Existing mechanisms for preventing traffic analysis focus on re-routing and padding. These prevention techniques have considerable resource and overhead requirements. Furthermore, padding is easily detectable and, in some cases, can introduce its own vulnerabilities. To address these shortcomings, we propose embedding real traffic in synthetically generated encrypted cover traffic. Novel to our approach is our use of realistic network protocol behavior models to generate cover traffic. The observable traffic we generate also has the benefit of being indistinguishable from other real encrypted traffic further thwarting an adversary's ability to target attacks. In this dissertation, we introduce the design of a proxy system called TrafficMimic that implements realistic cover traffic tunneling and can be used alone or integrated with the Tor anonymity system. We describe the cover traffic generation process including the subtleties of implementing a secure traffic generator. We show that TrafficMimic cover traffic can fool a complex protocol classification attack with 91% of the accuracy of real traffic. TrafficMimic cover traffic is also not detected by a binary classification attack specifically designed to detect TrafficMimic. We evaluate the performance of tunneling with independent cover traffic models and find that they are comparable, and, in some cases, more efficient than generic constant-rate defenses. We then use simulation and analytic modeling to understand the performance of cover traffic tunneling more deeply. We find that we can take measurements from real or simulated traffic with no tunneling and use them to estimate parameters for an accurate analytic model of the performance impact of cover traffic tunneling. Once validated, we use this model to better understand how delay, bandwidth, tunnel slowdown, and stability affect cover traffic tunneling. Finally, we take the insights from our simulation study and develop several biasing techniques that we can use to match the cover traffic to the real traffic while simultaneously bounding external information leakage. We study these bias methods using simulation and evaluate their security using a Bayesian inference attack. We find that we can safely improve performance with biasing while preventing both traffic analysis and defense detection attacks. We then apply these biasing methods to the real TrafficMimic implementation and evaluate it on the Internet. We find that biasing can provide 3-5x improvement in bandwidth for bulk transfers and 2.5-9.5x speedup for Web browsing over tunneling without biasing.

The aim of study was to examine the effects of the world's most challenging mountain ultramarathon (Tor des Geants [TdG]) on running mechanics. Mechanical measurements were undertaken in male runners (n = 16) and a control group (n = 8) before (PRE), during (MID), and after (POST) the TdG. Contact (tc) and aerial (ta) times, step frequency (f), and running velocity (v) were sampled. Spring-mass parameters of peak vertical ground-reaction force (Fmax), vertical downward displacement of the center of mass (Deltaz), leg-length change (DeltaL), and vertical (kvert) and leg (kleg) stiffness were computed. Significant decreases were observed in runners between PRE and MID for ta (P < .001), Fmax (P < .001), Deltaz (P < .05), and kleg (P < .01). In contrast, f significantly increased (P < .05) between PRE and MID-TdG. No further changes were observed at POST for any of those variables, with the exception of kleg, which went back to PRE. During the TdG, experienced runners modified their running pattern and spring-mass behavior mainly during the first half. The current results suggest that these mechanical changes aim at minimizing the pain occurring in lower limbs mainly during the eccentric phases. One cannot rule out that this switch to a "safer" technique may also aim to anticipate further damages.

The Stock Identification Methods Working Group (SIMWG) worked by correspondence in 2016. The working group was chaired by Lisa Kerr (USA). The work plan for SIMWG in 2016 comprised four Terms of Reference (ToR), some of which are continuing goals for SIMWG: a ) Review recent advances in stock identification methods; b ) Build a reference database with updated information on known biological stocks for species of ICES interest; c ) Provide technical reviews and expert opinions on matters of stock identifica-tion, as requested by specific Working Groups and SCICOM; d ) Review and report on advances in mixed stock analysis, and assess their po-tential role in improving precision of stock assessment. ToR a) is an ongoing task of SIMWG in which we provide a comprehensive update on recent applications of stock identification techniques to ICES species of interest, summa-rize new approaches in stock identification, and novel combinations of existing applica-tions. ToR b) is a multi-annual ToR in which SIMWG has taking steps to build a reference data-base consisting of SIMWG reviews of issues of stock identity for ICES species. ToR c) is a key ongoing task by SIMWG in which we addresses specific requests by ICES working groups for technical advice on issues of stock identity. This year we provided advice on mackerel in the Northeast Atlantic as requested by WGWIDE. ToR d) is a multi-annual ToR that is focused on tracking developments in the application of mixed stock analysis and the integration of this information into assessment and management.

Objetivo: Analizar las variaciones en el proceso de confirmación diagnóstica entre unidades de cribado, las variaciones en los resultados de cada episodio y la relación entre las tasas de las diferentes pruebas de confirmación diagnóstica y las de detección de lesiones. Método: Estudio observacional de las variaciones de las tasas estandarizadas de pruebas diagnósticas y de detección de lesiones, en 34 unidades de cribado de los programas poblacionales de detección precoz de cáncer de mama, de tres comunidades autónomas, en el periodo de 2002 a 2011. Resultados: Las razones de variación entre los percentiles 25-75 en las tasas de realización de pruebas diagnósticas oscilaron entre 1,68 (recitaciones) y 3,39 (punción-aspiración con aguja fina). En las tasas de detección de lesiones benignas, carcinoma ductal in situ y cáncer invasivo fueron, respectivamente, 2,79, 1,99 y 1,36. Se encontró una relación positiva entre las tasas de realización de pruebas y las tasas de detección en punción-aspiración con aguja fina y lesiones benignas (R²: 0,53), punción-aspiración con aguja fina y carcinoma invasivo (R²: 0, 28), biopsias cerradas y lesiones benignas (R²: 0,64), biopsias cerradas y carcinoma ductal in situ (R²: 0,61), y biopsias cerradas y carcinoma invasivo (R²: 0,48). Conclusiones: Se observaron variaciones en la realización de pruebas invasivas entre las unidades de detección precoz de cáncer de mama de mayor magnitud que las de detección de lesiones. Las unidades con más pruebas de punción-aspiración con aguja fina tienen mayores tasas de detección de lesiones benignas, y las que realizan más biopsias cerradas detectan más lesiones benignas y cáncer.
