Music education and community development in Vancouver's Downtown Eastside : an ethnographic case study of the Carnegie Centre Jazz Band
Creators: name: Ceschi-Smith, Antonia
Publisher: name: University of British Columbia
Year: 2014

description: This ethnographic case study focuses on the Carnegie Centre Jazz Band, a city-run community music program for adult learners at the Carnegie Centre, a community centre in the heart of Vancouver’s most aggrieved and marginalized area, the Downtown Eastside (DTES). I have been playing with the Carnegie Jazz Band, a free and open program at the Centre, since January 2010. As a participant-observer between February and April 2013, I conducted three private audio-recorded interviews with twelve of the fifteen regular members of the band who consented to participate, including Brad Muirhead, the bandleader. They provided information on their reasons for joining the band, why they continue to participate, what they gain from the experience, and what they hope for as outcomes of their participation. In this thesis, I examine the benefits that music making, specifically jazz and creative improvisation, provide for the band members, showing how they see themselves as music-makers within the program, identifying the challenges they face in participating, and situating their involvement in the larger paradigms of community music and communities of practice. The factors that motivate the individual members of the band to participate are myriad, but they all share an interest in and a commitment to supporting one another’s learning. One of the main findings of this case study is that approaching music-making with an aesthetic and ethos of improvisation is central to the band’s success in the aggrieved and marginalized DTES.

description: We have entered the era of explosive transient astronomy, in which upcoming real-time surveys like the Large Synoptic Survey Telescope (LSST), the Palomar Transient Factory (PTF) and Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) will detect supernovae in unprecedented numbers. Future telescopes such as the James Webb Space Telescope may discover supernovae from the earliest stars in the universe and reveal their masses. The observational signatures of these astrophysical transients are the key to unveiling their central engines, the environments in which they occur, and to what precision they will pinpoint cosmic acceleration and the nature of dark energy. We present a new method for modeling supernova light curves and spectra with the radiation hydrodynamics code RAGE coupled with detailed monochromatic opacities in the SPECTRUM code. We include a suite of tests that demonstrate how the improved physics is indispensable to modeling shock breakout and light curves.

description: Advances in device fabrication, modelling and design techniques have made wide band, low noise cryogenic amplifiers available at frequencies up to 106 GHz. Microwave radiometry applications as used in radio astronomy capitalize on the low noise and large bandwidths of these amplifiers. Radiometers must be carefully designed so as to preclude sensitivity degradations caused by small, low frequency gain fluctuations inherent in these amplifiers.

description: Recent empirical evidence provided by Bernard et al. (2010) and Broda and Weinstein (2010) shows that a significant share of product creation and destruction in U.S. industries occurs within existing firms and accounts for a significant share of aggregate output. In the present paper, and consistent with this evidence, we relax the standard assumption of mono-product firms that is typically made in dynamic general equilibrium (DSGE) models. We develop a DSGE model with multi-product firms and endogenous markups to assess the implica- tions of the intra-firm extensive margin on business cycle fluctuations. In this environment, the procyclicality of product creation emerges as a consequence of firms’ strategic interactions. Due to the proliferation effect in- duced by firm-level adjustments in product scope, we show that our model embodies a quantitatively important magnification mechanism of aggregate shocks.

description: We propose a splitting method for solving an equilibrium problem involving the sum of two bifunctions satisfying standard conditions. We prove that this problem is equivalent to find a zero of two appropriate maximally monotone operators. Our algorithm is a consequence of the Douglas--Rachford splitting applied to this auxiliary monotone inclusion. Connections between monotone inclusions and equilibrium problems are studied.

description: In questo libro pubblicato in Spagnolo sotto il titolo “URBANIZACIONES  CERRADAS RESIDENCIALES, PERSPECTIVAS DE DERECHO URBANÍSTICO Y DE DERECHO CIVIL”, si studiano le urbanizzazioni con perimetro chiuso e sorvegliato in Argentina, chiamate in inglese “gated community”, in cui le classi benestanti della società si sono isolate dal resto della città.

Nei due primi capitoli si effettua una ampia considerazione dei gravi problemi sociali e urbanistici che hanno determinato lo sviluppo di questo nuovo habitat in Argentina, problemi non considerati praticamente dai giuristi e sottolineato dai sociologi e urbanisti.
 
Si continua con l’analisi della giurisprudenza argentina in contrasto con la giurisprudenza degli Stati Uniti, l’ordinamento urbanistico di importanti comuni argentini, e finalmente gli aspetti civilistici in cui si illustrano le controversie dottrinarie rispetto al tipo di diritti reali applicabili, senza dimenticare il diritto comparato, specialmente il diritto francese che scoraggia questo tipo di sviluppo.

Il libro contiene un’appendice con il testo completo della normativa urbanistica dei comuni e dei modelli di regolamenti e statuti utilizzati nelle diverse città.

description: Despite the official neutrality maintained by Spain throughout the First World War, the conflict had a considerable impact on that country’s internal politics. The political stances taken gave rise to a process that divided society into two opposing sectors from the very first months of the war. As a result, the entire system of the Restoration was affected by a grave crisis that reached its peak in the summer of 1917. As this process unfolded, the intellectuals, the diverse political groupings, the unions, the ''Juntas de Defensa'' (Defence Committees) and Catalan nationalism took on roles of great importance.

description: In this paper we study the functional central limit theorem for stationary Markov chains with self-adjoint operator and general state space. We investigate the case when the variance of the partial sum is not asymptotically linear in n; and establish that conditional convergence in distribution of partial sums implies functional CLT. The main tools are maximal inequalities that are further exploited to derive conditions for tightness and convergence to the Brownian motion.

Building the pollen wall : the role of tapetum transport proteins and sporopollenin translocation in the formation of the specialized cell wall encasing Arabidopsis thaliana pollen
Creators: name: Quilichini, Teagen Danielle
Publisher: name: University of British Columbia
Year: 2014

description: A durable framework of sporopollenin and a lipid-rich pollen coat form the outer (exine) wall encasing pollen grains. The sporopollenin and pollen coat constituents of the exine are contributed by surrounding sporophytic tapetal cells by pre- and post-mortem events, respectively. The objective of this study was to investigate the transport and assembly of exine components from tapetal cells to developing pollen in the anthers of Arabidopsis thaliana. High-pressure freezing/freeze substitution and transmission electron microscopy revealed the sequence of developmental events in the anther that lead to sporopollenin deposition to form the exine and the dramatic differentiation and death of the tapetum, which produces the pollen coat. Through its tight co-expression with genes required for sporopollenin biosynthesis, a member of the ATP-binding cassette transporter superfamily, ABCG26, was found to be expressed preferentially in tapetal cells during early exine formation, and identified as a candidate gene encoding a sporopollenin export protein. Phenotypic abnormalities in the abcg26 mutant were first apparent in early uninucleate microspores as a lack of exine formation and sporopollenin deposition, and indicated that ABCG26 is required for normal male fertility, exine formation and pollen maturation. Further, two-photon microscopy of abcg26 anthers revealed large fluorescent vacuoles in tapetal cells with corresponding loss of fluorescence on microspores, consistent with abnormal ABCG26-mediated export activity in the mutant. These tapetum inclusions were not observed in double mutants of abcg26 and genes encoding the proposed sporopollenin polyketide biosynthetic metabolon (ACOS5, PKSA PKSB and TKPR1), providing a genetic link between transport by ABCG26 and polyketide biosynthesis. Genetic analysis also showed that hydroxycinnamoyl spermidines, known components of the pollen coat, were exported from tapeta prior to programmed cell death in the absence of polyketides, raising the possibility that they are incorporated into sporopollenin prior to pollen coat deposition. I propose a model where ABCG26-exported polyketides traffic from tapetal cells to form the sporopollenin backbone, in coordination with trafficking of additional constituents prior to tapetum programmed cell death.

description: Nel diritto argentino la proprietà ed i diritti reali su immobili si devono trasmettere in contratto sotto la forma strumentale pubblica. È abituale che prima si faccia una bozza in documento privato compiendo anche la tradizione del bene. In quel caso la proprietà non si è trasmessa avendo il creditore, un diritto personale a richiedere la forma strumentale pubblica del contratto, senza la possibilità (tranne che lo permetta la legislazione provinciale) di pubblicizzare nel registro immobiliare questo diritto. Se un altro creditore del proprietario dell’immobile riesce ad annotare nel registro il suo diritto, si produce una situazione  che ha generato grandi discussioni e diverse soluzioni nella dottrina e nella giurisprudenza.

South African volunteers served in various geographical campaigns, ranging from the Western Front (1916-1918), Egypt (1916), and Palestine (1917-1918), amongst others. Furthermore, the South African war experience also differed due to the contrasting roles tasked to separate army units, functions that were largely prescribed on the basis of race. The South African Native Labour Contingent and Cape Corps Labour Battalion were restricted to auxiliary roles, whilst the 1st South African Infantry Brigade and Cape Corps Infantry Battalion adopted armed functions.

Aggregazioni Territoriali e Strategia Imprenditoriale nel Turismo Marittimo e Intercostiero”, under
the supervision of Prof. Asterio Savelli director of the University of Bologna group: “Strategie
imprenditoriali e aggregazioni territoriali nel turismo intercostiero della regione adriatica”.
A plan from different departments has been made in order to evaluate the possibilities of a tourism
integration among Western and Eastern countries, in particular along the two coasts of the Adriatic
Sea. In a shrinking world, a new perspective is needed in order to re-discover the common values
among two different concepts of life, one as a part of the free market, the other deriving from the
communist era. In my opinion, the link between the two areas is the common cultural heritage
deriving from the Roman Empire and later the Austrian Empire, now under the UNESCO
protection. A special value is related to the natural richness of a wonderful landscape, where
mountains parallel the coasts, enriched by marine and terrestrial parks, and hundreds of islands.

Questo lavoro deriva da un programma nazionale PRIN 2007, “Oltre la Linea di Costa.

dal docente di Sociologia all’Università di Bologna, prof. Asterio Savelli, il cui piano di lavoro
locale aveva titolo: “Strategie imprenditoriali e aggregazioni territoriali nel turismo intercostiero
della regione adriatica”.
Il progetto mira a valutare i valori comuni dei paesi che si affacciano sulle due coste dell’Adriatico,
per individuare una nuova tipologia di turismo geograficamente, socialmente ed economicamente
integrato.
Si può dire che dalle nostre ricerche sia emerso che i valori comuni, al di là delle diverse opzioni
politiche seguite dai Paesi occidentali o orientali, consistano nell’eredità condivisa della tradizione
storica, nella ricchezza del patrimonio culturale sotto l’egida dell’ UNESCO e nell’incomparabile
patrimonio naturale di rilievi che affiancano parchi terrestri e marini, lungo una costa arricchita da
un’interminabile collana di isole su un mare che consente facilità di scambi come un fiume.
A note on the effect of market power in Ricardian economies

description: We argue that it is the number of agents using market power, rather than the use of market power itself, that may drive Ricardian economies into autarchy. As a consequence, the monopoly equilibrium outcome Pareto-dominates the oligopoly one. Thus, counter-intuitively, a non monotonic relationship between number of agents endowed with market power and economic efficiency may emerge.

description: This paper introduces a new approach for simulating magnetic properties of nanocomposites comprising magnetic particles embedded in a non-magnetic matrix, taking into account the 3D structure of the system in which particles' positions correctly mimic real samples. The proposed approach develops a multistage simulation procedure in which the size and distribution of particles within the hosting matrix is firstly attained by means of the Cell Dynamic System (CDS) model. The 3D structure provided by the CDS step is further employed in a Monte Carlo (MC) simulation of zero-field-cooled/field-cooled (ZFC/FC) and magnetic hysteresis loops ($M \times H$ curves) for the system. Simulations are aimed to draw a realistic picture of the as-produced ultra-thin films comprising maghemite nanoparticles dispersed in polyaniline. Comparison (ZFC/FC and $M \times H$ curves) between experiments and simulations regarding the maximum of the ZFC curve ($T_{\scriptsize MAX}$), remanence ($M_R/M_s$) and coercivity ($H_C$) revealed the great accuracy of the multistage approach proposed here while providing information about the system's morphology and magnetic properties. For a typical sample the value we found experimentally for $T_{\scriptsize MAX}$ (54 K) was very close to the value provided by the simulation (53 K). For the parameters depending on the nanoparticle clustering the experimental values were consistently lower ($M_R/M_s$ = 0.32 and $H_C$ = 210 Oe) than the values we found in the simulation ($M_R/M_s$ = 0.53 and $H_C$ = 274 Oe). Indeed, the approach introduced here is very promising for the design of real magnetic nanocomposite samples with optimized features.

description: We analyze the propagation of gravitational waves (GWs) in an asymptotically de-Sitter space by expanding the perturbation around Minkowski and introducing the effects of the Cosmological Constant ($Λ$), first as an additional source (de-Donder gauge) and after as a gauge effect ($Λ$-gauge). In both cases the inclusion of the Cosmological Constant $Λ$ impedes the detection of a gravitational wave at a distance larger than $L_{crit}=(6\sqrt{2}πf \hat{h}/\sqrt{5})r_Λ^2$, where $r_Λ=\frac{1}{\sqrtΛ}$ and f and $\hat{h}$ are the frequency and strain of the wave respectively. We demonstrate that $L_{crit}$ is just a confirmation of the Cosmic No hair Conjecture (CNC) already explained in the literature.

We find the surprising feature that the ratio of the length scales associated with states centered on vortex and anti-vortex topological defects can be arbitrarily varied but that fractionalization of quantum numbers such as charge is unaffected. We discuss this situation from a symmetry point of view and present numerical results for a specific lattice model realization of this scenario.

description: Die funktionell einwandfreie Harnabteilung nach Nierentransplantation ist eine wichtige Voraussetzung für die stabile Transplantatfunktion. Neben immunologischen, infektiösen und vaskulären Problemen stellen die urologischen Komplikationen eine große Gefahr für die Transplantatfunktion dar. Es wurden die Daten von 794 nierentransplantierten Patienten, die in der Zeit von 1983 bis 1997 im NTZ Halle transplantieren wurden, auf urologische Komplikationen (Urinfisteln, Ureterstenosen) retrospektiv analysiert. Untersucht wurden unter anderem die Einfluss bestimmte Faktoren wie das Alter der Patienten, Grunderkrankungen, Länge der kalten Ischämiezeit, Erst- oder Folgetransplantationen und HLA-Kompatibilität auf die Rate urologischer Komplikationen. Weitere Informationen wie die Lokalisation der Komplikationen, zeitliches Auftreten der Komplikationen, Diagnostik und Therapien der urologischen Komplikationen wurden erfasst. Urologische Komplikationen fanden sich bei 91 Patienten (11,5%). Es handelte sich um 63 Urinfisteln und 28 Ureterstenosen. Insgesamt zeigt der Inzidenz urologischer Komplikationen im Beobachtungszeitraum keine wesentliche Änderung.
description: The efficient urinary drainage is necessary for kidney transplantation. Urological complications are the main risks for the functioning of the transplant kidney next to immunologic, infectios and vascular problems. The data of 794 patients after kidney transplantation in the time between 1984 and 1997 at the "Nierentransplantationszentrum" in the department of urology at the Martin-Luther-university Halle-Wittenberg were analysed retrospectively. Aim of the study was the evaluation of urinary fistula and ureteral stenosis. Factors like age of donor and recipient, attendant diseases, ischemic time, quantity of kidney transplantation and HLA compatibility were analysed compared to urologic complications. More informations were collected like localisation of the fistula or stenosis, time of appearance, diagnostic and therapy. The incidence of urological complications following kidney transplantation was 91 of 794 cases (11.5%). 63 of these were urinary fistula and 28 ureteral stenosis. The number of complications has been stable over the years, despite the fact that in the early 1990's important changes of operation technique and the protocol of immunosuppression were established.

description: The Einstein rings and proper motions of nearby stars tend to be large. Thus, every year some foreground stars within a few hundred parsecs of Earth induce gravitational lensing events in background stars. In some of these cases, the events may exhibit evidence of planets orbiting the nearby star. In fact, planets can even be discovered during relatively distant passages. Here, we study the lensing signatures associated with planets orbiting nearby high-proper-motion stars. We find the following. (1) Wide-orbit planets can be detected for all distances of closest approach between the foreground and background stars, potentially producing independent events long before and/or after the closest approach. (2) Close-orbit planets can be detected for intermediate distances of closest approach, producing quasiperiodic signatures that may occur days or weeks before and after the stellar-lens event. (3) Planets in the so-called 'zone for resonant lensing' can significantly increase the magnification when the distance of closest approach is small, making the stellar-lens event easier to detect, while simultaneously providing evidence for planets. Because approaches close enough to allow planets to be detected can be predicted, we can plan observing strategies to take advantage of the theoretical framework built in this paper, which describes the sequence of expected effects in terms of a sequence of detection regimes.

Der Fragebogen wurde per Post u.a. allen erwachsenen Mitgliedern einer Selbsthilfegruppenorganisation zugesandt und eine Onlineversion des Fragebogens veröffentlicht. 271 Patienten wurden in die Studie eingeschlossen. Das durchschnittliche Alter beträgt 27 Jahre. Fast 50% der Teilnehmer geben ein lumbales Lähmungsniveau an. Die Befragten machten Angaben zu Operationen aufgrund assoziierter Erkrankungen. Der Median des Barthel Index lag bei 55, was davon zeugt, dass mehr als die Hälfte der Teilnehmer bei den Aktivitäten des täglichen Lebens auf Hilfe angewiesen sind. Je ca. 30% der Teilnehmer arbeiten in einem normalen Arbeitsverhältnis oder in einer beschützenden Werkstatt. Die Arbeitslosenquote liegt deutlich über der Deutschlands. Bezüglich der Wohnsituation und in finanzieller Hinsicht sind viele Teilnehmer auf die Unterstützung ihrer Eltern angewiesen. 89% der Befragten sind mit ihrer gesamten Lebenssituation ausreichend zufrieden. Die drängendsten Probleme der Teilnehmer betreffen Fragen der ärztlichen Versorgung, Arbeit und Wohnsituation. Der Barthel Index korreliert besser als das Lähmungsniveau mit assoziierten Erkrankungen und der Lebenssituation. Es wird deutlich, dass auch erwachsene Patienten mit Spina bifida vielfach auf Hilfe angewiesen und in diversen Lebensbereichen Verbesserungen notwendig sind. In Bezug auf die medizinische Versorgung sehen viele Teilnehmer Defizite. Dies gehört zu den wichtigsten Problemen der Befragten.
Vertical relations and number of channels in quality-differentiated markets

Subjects: SECS-P/01 Economia politica

description: Double marginalization causes inefficiencies in vertical markets. This paper argues that such inefficiencies may be beneficial to final consumers in markets producing vertically differentiated goods. The rationale behind this
result is that enhancing efficiency in high-quality supply chains through vertical integration may drive out of the market low-quality ones, thus affecting market structure. As a consequence, restoring-efficiency vertical
integration may reduce consumer surplus, even in the absence of foreclosure strategies by the newly integrated firms. From a policy standpoint, our paper
suggests that input and/or customer foreclosure should not be considered as the only source of antitrust concern when assessing the effects of vertical integration.
Vertical distribution of carbon dioxide, water vapour, momentum and energy exchange within and above a forest stand affected by the mountain pine beetle
Creators: name: Emmel, Carmen
Publisher: name: University of British Columbia
Year: 2014

description: The mountain pine beetle (MPB) has killed vast areas of pine forest in British Columbia, Canada converting forests from carbon sinks to sources. Different management options for these forests exist ranging from no treatment to complete removal of the infested forest (clearcut). The MPB attack and the following management alter the microclimate and carbon balance of affected stands. An intensive field campaign was conducted in the summer of 2010 in an affected forest without treatment in the interior of British Columbia. Eddy covariance, radiation, temperature, humidity and carbon dioxide (CO₂) measurements were made at seven heights on a tower within and above the canopy. This dissertation assessed the impact of the MPB attack and the structure of the disturbed canopy on the contribution of various vegetation layers (ground, secondary structure, overstory) to exchanges of CO₂, water vapour (H₂O), momentum and sensible heat. Previous research has shown that forests without treatment can return to being carbon sinks faster than clearcut sites. It was hypothesized that the rich secondary structure (mostly immature trees that survived the beetle attack) was responsible for this fast recovery. The current dissertation showed that canopy layers in this sparse and open-canopy stand were aerodynamically well coupled with the atmosphere above and allowed 60 % of photosynthetically active radiation to reach the ground. Given these favorable light conditions, the secondary structure was indeed responsible for a large proportion of the CO₂ uptake; however, the understory (< 1 m high) contributed at least equally to the CO₂ uptake. A dissimilarity in the vertical distribution of sources and sinks of CO₂, H₂O and sensible heat was found. The dissimilarity between CO₂ and H₂O was caused by the differences in water use efficiency of the different vegetation layers. Gradient-diffusion theory (K-theory) applicability was examined in order to guide modeling of stand microclimates and growth conditions. Momentum flux (shear stress) could be adequately determined using K-theory and an adjusted length scale. In the case of the other scalars, the use of K-theory was found to be problematic due to counter-gradient fluxes, the inability to resolve gradients and fluxes and/or source scales.

We study the mass generation of the thermal and/or dense medium and the collective excitation called plasmino, by considering the spectral function of fermion and its dispersion relation. Our results are very different from those of the hard thermal loop method: for zero density, there is no thermal mass or plasmino in any phase. Plasmino in deconfined phase is not allowed in $D4/D8$ set up. In the confined phase, there is plasmino modes only for a window of density.

Drei Protokollvarianten des Comet Assay (A/A, A/N, N/N) sind zu diesem Zweck für pflanzliche Zellkerne etabliert worden. DNA-Effekte von Genotoxinen verschiedener Wirkgruppen (MMS/MNU, MH, Bleomycin, Mitomycin C) sowie Reparaturverläufe nach Alkylantien- bzw. Bleomycin-Behandlung wurden vergleichend untersucht. Mit dem Comet Assay konnten auch adaptative Vorgänge, vergleichbar der "Clastogenen Adaptation", erfasst werden. Der Comet Assay wurde zudem mit Fluoreszenz in situ Hybridisierung (FISH) sowie Durchflusscytometrie kombiniert. Dadurch wurde die Lösung weitergehender Fragestellungen hinsichtlich der Beteiligung spezifischer Chromatin-Domänen an der Schweifbildung, des Einflusses der Zellzyklusphase auf die DNA-Migration sowie der Enstehung von Aberrationsclustern in Heterochromatinbereichen ermöglicht.
description: The comet assay is a micro-electrophoretic method for the evaluation of genotoxic effects. The portion of nuclear DNA which migrates towards the anode forming the comet tail is captured fluorometrically as a measure for DNA damage. This thesis describes experiments to establish applicable conditions for efficient and reproducible genotoxic testing with the comet assay in plants using Vicia faba, Hordeum vulgare and Arabidopsis thaliana. To this end three variants of the comet assay protocol (A/A, A/N and N/N) were introduced for plant cell nuclei. DNA effects of chemicals belonging to different classes of mutagens (MMS/MNU, MH, Bleomycin, Mitomycin C) as well as repair kinetics after alkylating and bleomycin treatment, respectively, have been investigated. The comet assay revealed also adaptive effects comparable to "clastogenic adaptation". Additionally, the comet assay was used in combination with fluorescence in situ hybridization (FISH) and flow cytometry. Thereby questions regarding the involvement of specific chromatin domains in tail formation, the influence of cell cycle stage on DNA migration as well as the origin of aberration clusters in heterochromatic regions could be solved.

Stochastic resonance in bistable systems with nonlinear dissipation and multiplicative noise: A microscopic approach

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The stochastic resonance (SR) in bistable systems has been extensively discussed with the use of {\it phenomenological} Langevin models. By using the {\it microscopic}, generalized Caldeira-Leggett (CL) model, we study in this paper, SR of an open bistable system coupled to a bath with a nonlinear system-bath interaction. The adopted CL model yields the non-Markovian Langevin equation with nonlinear dissipation and state-dependent diffusion which preserve the fluctuation-dissipation relation (FDR). From numerical calculations, we find the following: (1) the spectral power amplification (SPA) exhibits SR not only for $a$ and $b$ but also for $τ$ while the stationary probability distribution function is independent of them where $a$ ($b$) denotes the magnitude of multiplicative (additive) noise and $τ$ expresses the relaxation time of colored noise; (2) the SPA for coexisting additive and multiplicative noises has a single-peak but two-peak structure as functions of $a$, $b$ and/or $τ$. These results (1) and (2) are qualitatively different from previous ones obtained by phenomenological Langevin models where the FDR is indefinite or not held.

How green is “green”? 
A corpus-assisted analysis of environmental discourse across forms of journalism

description: Il presente contributo mira ad esplorare alcuni aspetti della rappresentazione del discorso ambientale in alcune forme del discorso giornalistico. In particolare, lo studio si concentra sull’analisi del profilo collocazionale del lemma “green” (“verde”), sia in un corpus specialistico di articoli apparsi sulla stampa quotidiana britannica e statunitense riguardanti tematiche ambientali, sia in un corpus specialistico di news blogs sull’ambiente. Nuovo genere mediale di giornalismo “partecipativo” (Herring et al. 2005, Bruns and Jacobs 2006), il news blogging sta infatti acquisendo sempre maggiore popolarità come articolata forma di giornalismo o, talora, di “anti-giornalismo” (Lasica 2001, Grossman 2004). Integrando gli strumenti e la metodologia dell’analisi del discorso assistita da corpora (si veda, Hardt-Mautner 1995, Miller 1999, 2006, Partington et al. 2004, Coffin and O’Halloran 2005, Baker 2006, Thompson and Hunston 2006,  Morley and Bayley 2009, Bevitori 2010, 2011a, 2011b, Bednarek 2010), e dell’apparato teorico-descrittivo denominato APPRAISAL SYSTEMS (Martin and White 2005), l’analisi prende in considerazione aspetti quantitativi e qualitativi del lemma, tracciandone i contesti tipici di occorrenza e co-occorrenza, ed evidenziandone le risorse valutative e/o “attitudinali” comunemente associate al termine. Dai risultati dell’indagine emerge una profonda differenza su come il lemma “green” viene costruito “socialmente” nelle due forme di giornalismo; mentre nei news blogs l’analisi rivela che il lemma tende ad associarsi tipicamente a risorse valutative positive, che hanno principalmente lo scopo di promuovere una cittadinanza attiva e partecipata, rivolta alla tutela e salvaguardia dell’ambiente, nella stampa, al contrario, il lemma “green” tende ad aggregarsi a formulazioni negative che mirano alla critica di comportamenti non eco-sostenibili.

Influence of the JAK2-V617F mutation on integrin-mediated adhesion to VCAM1 in murine and human cell lines in the context of classical Philadelphia-negative myeloproliferative neoplasms

description: JAK2-V617F is an activating point mutation of the intracellular tyrosine kinase JAK2 and the most prevalent mutation in patients suffering from Philadelphia-negative myeloproliferative neoplasm (MPN). Besides debilitating constitutional symptoms, myelofibrosis, and leukemic transformation, the MPN phenotype comprises extramedullary hematopoiesis and an increased risk for arterial and venous thrombosis. JAK2 has recently been shown to mediate chemokine-induced activation of integrin adhesion molecules thereby enabling increased cell adhesion and tissue-specific homing of leukocytes. By using an overexpression model of JAK2-V617F in murine BaF3 cells and JAK2-V617F-positive human HEL cells treated with JAK2-specific kinase inhibitors or shRNAs, we herein demonstrate that aberrant JAK2-V617F signaling is associated with increased integrin-mediated cell adhesion to Vascular Cell Adhesion Molecule 1 (VCAM1). In BaF3 cells, an increase in integrin affinity to VCAM1, but not regulation of β1-integrin surface expression, seems to contribute to the mechanism underlying the adhesion phenotype. We argue that the observed enhancement of integrin-mediated cell adhesion in JAK2-V617F-positive cells might contribute to the clinical phenomena of thrombosis and extramedullary hematopoiesis occurring in MPN patients and, hence, deserve to be studied in more detail.

description: Atherosklerose ist ein chronisch-entzündlicher Prozess, der die Grundlage für kardiovaskuläre Erkrankungen bildet. Die nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB)-Aktivität ist bei der Entstehung von Atherosklerose erhöht. Der NF-κB essentielle Modulator (NEMO) reguliert als Baustein des kanonischen NF-κB-Signalwegs die NF-κB-Aktivität. In der vorliegenden Arbeit konnte festgestellt werden, dass die NF-κB-Aktivität durch die Phosphorylierung von NEMO durch die Glykogensynthasekinase-3β (GSK-3β) beeinflusst werden kann. Dabei stellten sich die Serinreste S8, S17, S31 und S43 von NEMO als Phosphorylierungsstellen der GSK-3β heraus. Des Weiteren konnte nachgewiesen werden, dass vakuoläre Strukturen wie frühe Endosomen und multivesikuläre bodies (MVB) wichtig für die Interaktion von NEMO und GSK-3β und somit für die NF-κB-Aktivität von Bedeutung sind. Die Arbeit trägt damit zum Verständnis des Entstehungsprozesses der Atherosklerose bei.

description: In this letter, we present the first experimental study of bridge structures in three-dimensional dry granular packings. When bridges are small, they are predominantly 'linear', and have an exponential size distribution. Larger, predominantly 'complex' bridges, are confirmed to follow a power-law size distribution. Our experiments, which use X-ray tomography, are in good agreement with the simulations presented here, for the distribution of sizes, end-to-end lengths, base extensions and orientations of predominantly linear bridges. Quantitative differences between the present experiment and earlier simulations suggest that packing fraction is an important determinant of bridge structure.

description: Wide-band LNAs suffer from a fundamental
trade-off between noise figure NF and source impedance
matching, which limits NF to values typically above 3dB.
Recently, a feed-forward noise canceling technique has been
proposed to break this trade-off. This paper reviews the
principle of the technique and its key properties. Although
the technique has been applied to wideband CMOS LNAs, it
can just as well be implemented exploiting transconductance
elements realized with other types of transistors. To
examplify this claim, measurement results on a bipolar
amplifier exploiting noise cancellation will also be presented.
