Authors: Schatz Michael , Zeiger Robert S. , Chen Wansu , Yang Su-Jau , Stanford Richard H. , Garris Cindy P. 
Published: April 2012

Background The relationships between validated quality of life tools and control tools have not been explored for rhinitis. This study was designed to determine relationships of the Mini–Rhinitis Quality of Life Questionnaire (MiniRQLQ) and the Rhinitis Control Assessment Test (RCAT) to each other regarding content and predictive abilities. Methods Participants were adult members of a large integrated care organization with an encounter diagnosis of rhinitis in the prior 2 years. Patients completed mailed questionnaires at baseline that contained the MiniRQLQ and the RCAT and three follow-up questionnaires that contained those tools as well as questions regarding missed work or school because of rhinitis and frequency and effectiveness of medications used for rhinitis. Medications dispensed during the follow-up year were obtained from computerized pharmacy records. Results of allergy tests were retrieved for patients seen in the Allergy Department. Results The final cohort included 1051 patients. Baseline RCAT scores were strongly correlated with baseline MiniRQLQ scores in both allergic (r = -0.80) and nonallergic (r = -0.84) patients. Baseline MiniRQLQ and RCAT scores we significantly related to patient reports of missed school/work, medication use, and effectiveness over the next 3 months and to dispensing during the following year of total and some individual rhinitis medications. Test–retest reliability, responsiveness, and a preliminary minimal important difference (>2.5) were shown for the RCAT, using the MiniRQLQ as an anchor. Conclusion The MiniRQLQ and RCAT are strongly related to each other and both predict subsequent rhinitis outcomes. Determining the comparative usefulness of these tools will require further study.

Published: April 2012

Background Paranasal sinuses are reservoirs for nitric oxide (NO), and humming facilitates nasal diffusion of NO. The nasal NO response to humming has previously been shown to be blunted with chronic sinusitis and nasal polyposis. We hypothesized that the nasal NO response to humming will be proportional to radiographic osteomeatal patency when comparing allergic rhinitis (AR) patients (without chronic sinusitis) with normal controls. Methods Nonsmoking subjects completed questionnaires and skin-prick testing. Subjects underwent sinus CT scanning, followed by exhaled (oral) and nasal NO sampling (with and without humming). Humming-to-quiet (H/Q) nasal NO ratios were calculated. Three-dimensional reconstructions were used to trace the osteomeatal complex (OMC) and measure minimum cross-sectional area. Lund-Mackay scores were also documented. Results A total of 33 subjects (22 women; mean age, 35.5 years) completed the study. Seventeen AR patients (5 IAR and 12 PAR) participated, as did 16 nonallergic controls. Among controls, quiet nasal NO levels—corrected for fractional exhaled NO—rose significantly with OMC area and fell significantly with Lund-Mackay scores (p < 0.05). However, we observed no proportionality between H/Q ratio and radiographic OMC patency. Conclusion Analysis of nasal NO samples taken under quiet conditions from normal controls was consistent with the paranasal sinuses acting as a reservoir of nasal NO and with OMC patency acting as a significant factor in NO diffusion. However, our results did not support a relationship between the nasal NO response to humming and radiographic OMC patency in a sample excluding subjects with severe rhinosinusitis.
Orbital Involvement in Pott's Puffy Tumor: A Systematic Review of Published Cases
Authors: Nisa Lluís , Landis Basile Nicolas , Giger Roland 
Published: April 2012

Background Pott's puffy tumor (PPT) is a frontal subperiosteal abscess associated with underlying frontal bone osteomyelitis. It represents a well-known source of sinogenic intracranial infection, but the orbital complications related to this entity are rarely reported. The goal of this study was to characterize the orbital involvement in PPT. Methods We performed a systematic review through a Medline search (1950–2010). The authors reviewed all cases of PPT, selecting those explicitly describing orbital complications associated with PPT. Results We screened 139 articles, of which 93 reported cases of PPT. Of these, 35 articles described a total of 42 cases presenting simultaneous orbital complications. Eyelid and/or periorbital edema was the most common finding in patients with orbital involvement, and preseptal cellulitis is by far the most prevalent orbital complication in PPT. Postseptal involvement (orbital cellulitis, subperiosteal abscess of the orbit, and orbital abscess) is much rarer. Although treatment of the classic PPT is surgical, only a minority of patients with orbital infection required orbital drainage. Most reported patients made a full recovery, without permanent sequelae. Conclusion Orbital infections are possible in patients with PPT. In contrast to surgical treatment of the frontal subperiosteal abscess, the orbital complications can be treated conservatively most of the time. Early diagnosis and aggressive therapy of the underling PPT are essential to avoid severe local or systemic complications.
«Prosuming» across Cultures: Youth Creating and Discussing Digital Media across Borders
Authors: Dezuanni Michael , Monroy-Hernandez Andres 
Published: April 2012

The Scratch Online Community enables young people to share their creative digital projects internationally with a level of ease that was impossible only a few years ago. Like all creative communities, Scratch is not just a space for sharing products, work, techniques and tips and tricks, but also a space for social interaction. Media literacy educators have unprecedented challenges and opportunities in digital environments like Scratch to harness the vast amount of knowledge in the community to enhance students’ learning. They also have challenges and opportunities to implement a form of digital media literacy education that is responsive to social and cultural representation. One role of digital media literacy is to help young people to challenge unfair and derogatory portrayals of people and to break down processes of social and cultural «othering» so that all community members feel included and safe to express themselves. This article considers how online community spaces like Scratch might draw on social interaction to enhance intercultural understandings and learning through dialogue and creative practice. The article uses statistics to indicate the amount of international interaction in the Scratch community. It then uses qualitative analysis of forum discussions to analyse the types of intercultural interaction that occurs.
La «Scratch Online Community» permite a los jóvenes compartir sus proyectos digitales internacionalmente con una facilidad impensable años atrás. Como todas las comunidades creativas de este tipo, no es solo un espacio para compartir productos, trabajos, técnicas o consejos, sino también un espacio para la interacción social. Los educadores del ámbito de la alfabetización en los medios encuentran en estas iniciativas retos y oportunidades sin precedentes para aprovechar el volumen de conocimiento de la comunidad y promover el aprendizaje. Ofrece también oportunidades para implementar una forma de alfabetización digital sensible a la representación social y cultural. Una de las funciones de la alfabetización digital es ayudar a los jóvenes a cuestionar representaciones y a romper con procesos de otredad para que los miembros de la comunidad puedan expresarse e integrarse en esos contextos. Este artículo analiza cómo estas comunidades, a través de la interacción social, pueden impulsar el entendimiento intercultural y el aprendizaje a través del diálogo y la práctica creativa. El artículo incluye estadísticas para indicar la cantidad de interacción internacional en la comunidad que se analiza (Scratch). Asimismo, también incluye análisis cualitativos a partir de discusiones en el foro, con el fin de analizar los tipos de interacción intercultural que se llevan a cabo.
The Digital Afterlife of Youth-Made Media: Implications for Media Literacy Education
Authors: Soep Elisabeth 
Published: April 2012

The digital age has fundamentally re-configured the relationship between makers and users. Every networked action by a user has the potential to be reinterpreted by other users. The original intentions of media makers emerge from this process in recontextualized form that I call the «digital afterlife». The phenomenon of digital afterlife has striking implications for youth-made media, which I explore in this article through an ethnographic analysis of behind-the-scenes activities among a group of young people working with Youth Radio, a California youth organization, where they create high-impact media. The case study examined here centers on a major investigative reporting initiative within Youth Radio – a transmedia series on child sex trafficking produced by a 21-year-old reporter in collaboration with veteran editors. The analysis reveals the ways in which youth media ceases to be «youth media», once it moves into its digital afterlife, given the extent to which the content gets re-produced, again and again, by adult institutions with their own histories, agendas, and political economies. The article concludes by identifying key dimensions of literacy that young people invent and deploy through their experiments with social and mobile media, including: discovery, analytics, network mobilization, and platform programming.La era digital ha reconfigurado las relaciones entre productores y usuarios. Las acciones en red son potencialmente reinterpretadas por otros usuarios. La intención de los productores mediáticos adquiere su sentido en este contexto que denominamos «el más allá digital». En este artículo analizamos cómo ha influido este fenómeno en las implicaciones de los medios y los jóvenes. El estudio se lleva a cabo a través del análisis etnográfico de las actividades llevadas a cabo por un grupo de jóvenes que trabajan creando productos mediáticos de gran impacto en una radio en California (Youth Radio). El estudio de caso que se incluye en este artículo se centra en una iniciativa de periodismo de investigación dentro de Youth Radio: una serie transmediática sobre el tráfico sexual infantil producida por un joven de 21 años con la ayuda de editores más veteranos. El análisis desvela la forma en que los medios «juveniles» dejan de serlo una vez que se convierten en un producto digital en sí, cuyo contenido se reproduce una y otra vez en manos de adultos e instituciones con su propia historia, organización y economía política. El artículo concluye identificando dimensiones clave de alfabetización que los jóvenes crean y emplean a través de su experimentación con los medios móviles y sociales, entre otros: el descubrimiento, el análisis, la movilización en red y la programación de plataformas.
Quand l’art réinvente la vie
Authors: Noury Mathieu , Lafontaine Céline 
Published: April 2012

Partant du principe selon lequel l’art contemporain offre un lieu d’étude privilégié à l’analyse sociologique des nouvelles représentations du corps et du vivant, cet article propose de prendre le cas de l’art transgénique d’Eduardo Kac comme terrain d’analyse de la représentation du vivant propre aux technosciences. Intégrant les a priori épistémologiques propres aux biotechnologies, l’art transgénique constitue un modèle idéal-typique du paradigme informationnel qui s’articule autour de trois éléments principaux : la communication, la technoscience et la génétique. Afin de rendre compte de cette représentation informationnelle du vivant, il sera analysé les discours d’Eduardo Kac sur deux de ses oeuvres majeures : GFP-Bunny (2000) et Genesis (1999).
D’une révolution l’autre : figures de l’engagement chez Hubert Aquin et Mordecai Richler
Authors: Lapointe Martine-Emmanuelle 
Published: April 2012

Dans le contexte littéraire québécois, on osera rarement comparer les oeuvres d’Hubert Aquin et de Mordecai Richler, écrivains aux convictions politiques radicalement opposées. Mais n’y aurait-il pas lieu de quitter le territoire de la politique nationale pour mieux réfléchir aux représentations de la révolution qui traversent leurs oeuvres respectives ? Aussi éloignées soient-elles, leurs oeuvres partagent une certaine fascination pour l’engagement révolutionnaire, lequel emprunte souvent la forme d’un idéal inatteignable, voire d’une pure fiction. Entre la révolution du Québec, appelée de ses voeux par le héros aquinien de Prochain épisode, et le spectre de la Révolution espagnole, fantasmée et reconstruite par plusieurs personnages richleriens, est-il possible d’établir des liens, d’esquisser des passages, de relever des effets d’écho ? Dans le cadre de cet article, il s’agira de se prêter au jeu de la comparaison, de se hasarder à formuler des pistes de lecture et de tenter de contourner le piège de la nationalisation de l’engagement littéraire.
Le nationalisme et la gauche au Québec
Authors: Béland Daniel , Lecours André 
Published: April 2012

L’un des aspects les plus intéressants du nationalisme québécois depuis les années 1960 est son ancrage à gauche. Comparé aux nationalismes flamand et catalan, par exemple, le nationalisme québécois est le plus souvent associé aux politiques égalitaristes d’inspiration sociale-démocrate. Bien qu’il existe une faction néolibérale au sein du mouvement indépendantiste, le nationalisme québécois semble inséparable de l’idée que le Québec forme une « société distincte » non seulement en raison de sa langue et de sa culture, mais également en raison de son modèle économique et social. L’objectif de cet article est d’expliquer et d’illustrer cet ancrage à gauche du nationalisme québécois dans le champ des politiques économiques et sociales depuis les années 1960. Centré sur le Québec, mais incluant une discussion d’autres cas, l’article met l’accent sur les rapports entre les acteurs, les idées économiques et les institutions politiques, notamment les partis.
Determining In Vivo Phosphorylation Sites Using Mass Spectrometry
Authors: Breitkopf Susanne B. , Asara John M. 
Published: April 2012

AbstractPhosphorylation is the most studied protein post‐translational modification (PTM) in biological systems, since it controls cell growth, proliferation, survival, and other processes. High‐resolution/high mass accuracy mass spectrometers are used to identify protein phosphorylation sites due to their speed, sensitivity, selectivity, and throughput. The protocols described here focus on two common strategies: (1) identifying phosphorylation sites from individual proteins and small protein complexes, and (2) identifying global phosphorylation sites from whole‐cell and tissue extracts. For the first, endogenous or epitope‐tagged proteins are typically immunopurified from cell lysates, purified via gel electrophoresis or precipitation, and enzymatically digested into peptides. Samples can be optionally enriched for phosphopeptides using immobilized metal affinity chromatography (IMAC) or titanium dioxide (TiO2) and then analyzed by microcapillary liquid chromatography/tandem mass spectrometry (LC‐MS/MS). Global phosphorylation site analyses that capture pSer/pThr/pTyr sites from biological sources sites are more resource and time consuming and involve digesting the whole‐cell lysate, followed by peptide fractionation by strong cation‐exchange chromatography, phosphopeptide enrichment by IMAC or TiO2, and LC‐MS/MS. Alternatively, the protein lysate can be fractionated by SDS‐PAGE, followed by digestion, phosphopeptide enrichment, and LC‐MS/MS. One can also immunoprecipitate only phosphotyrosine peptides using a pTyr antibody followed by LC‐MS/MS. Curr. Protoc. Mol. Biol. 98:18.19.1‐18.19.27. © 2012 by John Wiley & Sons, Inc.
From Second‐Wave to Postructuralist Feminism
Authors: Marie Hardin 
Published: March 2012

AbstractIn this essay, we trace the evolution of scholarship on media representations of women's sports. Introspection about our own work in this area has brought us to consider the potential ofthird‐wave/poststructuralistfeminism as a theoretical lens for our own critical inquiry into depictions of women's sports. We trace the trajectory of our work by first reviewing second‐wave feminist critiques of representations of women in sport and the solutions stemming from those critiques. We then consider the development of our own research and the possibilities of a poststructuralist lens in that work, assessing how such a perspective might offer useful alternatives to standard, Gramscian‐oriented critiques of the coverage of women's sports.
How Should We Think About Audience Power in the Digital Age?
Authors: Turow Joseph 
Published: March 2012

AbstractThis chapter emphasizes the workings of corporate power in people's core relationships to the emerging digital media system. Its aim is to provide a counterbalance to a perspective with a lot of traction among contemporary academics: that the best way to think about audiences in the new age is to emphasize that individual audience members are exercising unprecedented control over the creation and distribution of media products. Focusing on the media‐buying sector of the advertising industry, this chapter outlines the contours of a new ecosystem of digital‐marketing companies that buys and sells data about online users without their permission or knowledge. This ecosystem raises a new version of the concerns about media's constructions of society for society that scholars first expressed in the late nineteenth and early twentieth centuries.
Corporate Carbon Strategies and Greenhouse Gas Emission Assessments: The Implications of Scope 3 Emission Factor Selection
Authors: Downie John , Stubbs Wendy 
Published: March 2012

ABSTRACTScholars and practitioners acknowledge the benefits of organizations understanding their contribution to global warming and implementing carbon management strategies to address climate change concerns. A key element of a carbon management strategy is to reduce emissions, which requires an assessment of a firm's greenhouse gas emissions. For most organizations the indirect (scope 3) emissions represent the largest portion of their total carbon footprint. When facility‐specific data are not available, firms are encouraged to use standard emission factors to calculate scope 3 emissions. This paper investigates how sampled Australian organizations assess their scope 3 emissions with respect to the emission factors they are using to convert activity data into units of carbon dioxide equivalent emission (CO2‐e), and the implications for producing an accurate emission assessment. The research study found that, where conversion information was not available in a recognized government publication, the use of varying conversion value sources resulted in wide discrepancies in reported emissions for like activities. This undermines the assessment quality, makes comparison of results across organizations difficult and can lead to inappropriate carbon management strategy choices and misallocation of resources.

Kinetic modeling of the photosynthetic growth of Chlamydomonas reinhardtii in a photobioreactor
Authors: Takache Hosni , Pruvost Jérémy , Cornet Jean‐François 
Published: April 2012

AbstractThe aim of this study was to establish and validate a model for the photosynthetic growth of Chlamydomonas reinhardtii in photobioreactors (PBRs). The proposed model is based on an energetic analysis of the excitation energy transfer in the photosynthesis apparatus (the Z‐scheme for photosynthesis). This approach has already been validated in cyanobacteria (Arthorspira platensis) and is extended here to predict the volumetric biomass productivity for the microalga C. reinhardtii in autotrophic conditions, taking into consideration the two metabolic processes taking place in this eukaryotic microorganism, namely photosynthesis and respiration. The kinetic growth model obtained was then coupled to a radiative transfer model (the two‐flux model) to determine the local kinetics, and thereby the volumetric biomass productivity, in a torus PBR. The model was found to predict PBR performances accurately for a broad set of operating conditions, including both light‐limited and kinetic growth regimes, with a variance of less than 10% between experimental results and simulations. © 2012 American Institute of Chemical Engineers Biotechnol.

Subjective uncertainty and limbic hyperactivation in obsessive‐compulsive disorder
Authors: Stern Emily R. , Welsh Robert C. , Gonzalez Richard , Fitzgerald Kate D. , Abelson James L. , Taylor Stephan F. 
Published: March 2012

AbstractObsessive‐compulsive disorder (OCD) is often associated with pathological uncertainty regarding whether an action has been performed correctly or whether a bad outcome will occur, leading to compulsive “evidence gathering” behaviors aimed at reducing uncertainty. The current study used event‐related functional magnetic resonance imaging to investigate neural functioning in OCD patients and controls as subjective certainty was rated in response to sequential pieces of evidence for a decision. Uncertainty was experimentally manipulated so that some decisions were associated with no “objective” uncertainty (all observed evidence pointed to one correct choice), whereas other decisions contained calculable but varying levels of objective uncertainty based on displayed probabilities. Results indicated that OCD patients differed from controls on decisions that contained no objective uncertainty, such that patients rated themselves as more uncertain. Patients also showed greater activation in a network of brain regions previously associated with internally‐focused thought and valuation including ventromedial prefrontal cortex, parahippocampus, middle temporal cortex, as well as amygdala and orbitofrontal cortex/ventral anterior insula. In the patient group, a significantly greater number of positive intersubject correlations were found among several of these brain regions, suggesting that this network is more interconnected in patients. OCD patients did not differ from controls on decisions where task parameters led to uncertainty. These results indicate that OCD is associated with hyperactivation in a network of limbic/paralimbic brain regions when making decisions, which may contribute to the greater subjective experience of doubt that characterizes the disorder.

Enhancing employee and organizational performance through coaching based on mystery shopper feedback: A quasi‐experimental study
Authors: Latham Gary P. , Ford Robert C. , Tzabbar Danny 
Published: March 2012

AbstractBased on reinforcement theory, a quasi‐experimental design was used to evaluate the effect of (a) feedback obtained from (b) a relatively neutral third party (namely, mystery shoppers) that was obtained on a (c) variable interval schedule for managers to use to (d) coach their employees. An interrupted time‐series design showed that both employee and organizational performance increased as a result of this intervention. Performance dropped when this intervention was cut back and, subsequently, discontinued. These results were replicated in two additional restaurants. © 2012 Wiley Periodicals, Inc.
