Making sense of race/ethnicity and gender in televised football: reception research among British students*

Abstract Most people today watch football by way of the mass media, sites that reproduce and transform ideologies and ideas surrounding racial/ethnic and gender identity. However, still little remains known as to what extent actual football viewers take up or resist these ideas. Drawing on a cultural studies perspective, this study tries to identify the dominant discourses that British television viewers use to assign meaning to race/ethnicity and gender in men’s and women’s football on television. Eleven focus groups of British students (n = 44) were utilized to explore these discourses. Our findings indicate that viewers from various ethnic backgrounds were largely compliant with the hegemonic media discourses about natural physicality in both gender and race/ethnic comparisons. At the same time, multiple negotiated/oppositional discourses were found in relation to women’s football that showed how other social practices contributed to such readings. Limitations and possible areas for future research are discussed.
A Random Graph Walk based Approach to Computing Semantic Relatedness Using Knowledge from Wikipedia

Determining semantic relatedness between words or concepts is a fundamental process to many Natural Language Processing applications. Approaches for this task typically make use of knowledge resources such as WordNet and Wikipedia. However, these approaches only make use of limited number of features extracted from these resources, without investigating the usefulness of combining various different features and their importance in the task of semantic relatedness. In this paper, we propose a random walk model based approach to measuring semantic relatedness between words or concepts, which seamlessly integrates various features extracted from Wikipedia to compute semantic relatedness. We empirically study the usefulness of these features in the task, and prove that by combining multiple features that are weighed according to their importance, our system obtains competitive results, and outperforms other systems on some datasets.
Maximal lifetime scheduling in sensor surveillance networks

This paper addresses the maximal lifetime scheduling problem in sensor surveillance networks. Given a set of sensors and targets in a Euclidean plane, a sensor can watch only one target at a time, our task is to schedule sensors to watch targets, such that the lifetime of the surveillance system is maximized, where the lifetime is the duration that all targets are watched. We propose an optimal solution to find the target watching schedule for sensors that achieves the maximal lifetime. Our solution consists of three steps: 1) computing the maximal lifetime of the surveillance system and a workload matrix by using linear programming techniques; 2) decomposing the workload matrix into a sequence of schedule matrices that can achieve the maximal lifetime; 3) obtaining a target watching timetable for each sensor based on the schedule matrices. Simulations have been conducted to study the complexity of our proposed method and to compare with the performance of a greedy method.
Fast Methods for Eikonal Equations: An Experimental Survey

Fast methods are very popular algorithms to compute time-of-arrival maps (distance maps measured in time units) solving the Eikonal equation. Since fast marching was proposed in 1995, it has been applied to many different applications, such as robotics, medical computer vision, fluid simulation, and so on. From then on, many alternatives to the original method have been proposed with two main objectives: reducing its computational time and improving its accuracy. In this paper, we collect the main single-threaded approaches, which improve the computational time of the standard fast marching method and study them within a common mathematical framework. Then, they are evaluated using isotropic environments, which are representative of their possible applications. The studied methods are the fast marching method with the binary heap, the fast marching method with Fibonacci heap, the simplified fast marching method, the untidy fast marching method, the fast iterative method, the group marching method, the fast sweeping method, the locking sweeping method, and the double dynamic queue method.
Preparation of filamentous hemagglutinin from Bordetella pertussis and assay for serum antibodies to filamentous hemagglutinin and pertussis toxin for clinical and public health laboratories

A procedure that is sufficiently simple and economical for use in clinical and public health laboratories for producing and purifying filamentous hemagglutinin (FHA) and determining antibodies to this major antigen of Bordetella pertussis in serum is described. High yields of FHA (40 to 80 mg/liter) were obtained in the supernatant by cultivating B. pertussis in modified CL medium. The FHA antigen was separated from pertussis toxin (PT) and other antigens by chromatography on hydroxylapatite. Removal of residual PT activity in the FHA fraction was effected by affinity absorption of PT with Fetuin immobilized to Sepharose 4B. The FHA was used as the antigen for determining titers of immunoglobulin G (IgG), IgA, and IgM to FHA in sera of patients with pertussis by an improved enzyme-linked immunosorbent assay. Development of the interfering background color commonly observed in conventional FHA enzyme-linked immunosorbent assay procedures was eliminated by washing the reaction wells with a buffer of high ionic strength before adding the peroxidase conjugates. In the absence of nonspecific background color, the reaction endpoints were easy to read. The FHA prepared by the procedure described was identical to a reference preparation of purified FHA in sodium dodecyl sulfate-polyacrylamide gel electrophoresis profiles and serological specificity assays. High yields of FHA were obtained from all four strains of B. pertussis tested in this study, indicating that the procedure for enhanced production of FHA may be generally applicable to other strains of B. pertussis. Results from tests of 50 serum specimens with clinical information on pertussis for FHA and PT antibodies by the assay procedures described exemplified the usefulness and caveats of serodiagnosis for pertussis.
Regulation of activation‐induced receptor activator of NF‐κB ligand (RANKL) expression in T cells

Receptor activator of NF‐κB ligand (RANKL) is a type II membrane protein of the TNF family and plays a critical role in the regulation of osteoclastogenesis. RANKL expressed on osteoblastic stromal cells has been shown to support osteoclast differentiation originated from hematopoietic precursors. Interestingly, RANKL is also expressed on cells of the immune system including T cells and dendritic cells. We have shown that anti‐CD3 could induce RANKL expression in T cell hybridoma A1.1 cells and splenic T cells. RANKL expressed on T cells could effectively induce osteoclast formation from the whole population of murine splenocytes. Furthermore, we have found that the induction of RANKL expression is solely dependent on TCR activation‐induced Ca2+ mobilization since its expression can be blocked by cyclosporine A and TMB‐8, a Ca2+ mobilization inhibitor. Additionally, treatment of A1.1 cells with ionomycin alone also strongly induces RANKL expression, while phorbol myristate acetate by itself does not. Moreover, although inhibition of c‐myc has significant effects on anti‐CD3‐induced Fas ligand (FasL) expression, we have found that the anti‐CD3‐induced RANKL expression is independent of c‐myc. Surprisingly, in contrast to its inhibitory effect on FasL expression, TGF‐β dramatically increased the expression of anti‐CD3‐induced RANKL expression. In addition to its potential role in immune responses, RANKL expressed on activated T lymphocytes may provide a mechanism for the communication between the immune and skeletal systems during immune responses and disease states such as rheumatoid arthritis.
Using cognitive work analysis and the strategies analysis diagram to understand variability in road user behaviour at intersections

In this article, an application of cognitive work analysis (CWA), using the strategies analysis diagram (SAD) method, to model performance variability in road transport, is presented. Specifically, the method was used to describe performance variability across four road user groups (drivers, cyclists, motorcyclists and pedestrians) when turning right at an urban signalised intersection. The analysis demonstrated that the method was able to identify a comprehensive range of strategies that road users can potentially use while turning right at an intersection, thereby describing a range of performance variability within intersection systems. Furthermore, the method identified constraints, disturbances, changes in circumstances and other influences on road user performance variability. It is concluded that the CWA/SAD approach was able to describe both the different ways in which activities can be executed and disturbances, situations and constraints that create performance variability. The implications of these findings for road design and intersection safety are discussed along with the benefits and drawbacks of the methodology used. Practitioner Summary: Recently, the strategies analysis diagram was proposed as a method to support the cognitive work analysis framework in modelling performance variability. This article evaluated this method within a complex sociotechnical system, namely road transport. The application provided insight into performance variability across road user groups when turning right at intersections.
The planetary system of upsilon Andromedae

The bright F8 V solar-type star upsilon Andromedae has recently been reported to have a system of three planets of Jovian masses. In order to investigate the orbital stability and mutual gravitational interactions among these extrasolar planets, both forward and backward integrations from the latest observed orbital elements for all three planets' orbits have been performed under the coplanar assumption. We reconfirm that the middle and the outer planet have strong interaction leading to large time variations in the eccentricities of these planets, which was shown by the previous studies. However, we discuss the validity of the ignorance of the innermost planet. We argue that this planetary system is likely to be stable and oscillate around current orbital elements since it was formed. We suggest that one possible way to produce these orbital elements: the innermost planet has very low eccentricity but the outermost planet has high eccentricity could be the interaction with the protostellar disc.
Identification of H-2Db-Specific CD8+ T-Cell Epitopes From Mouse VEGFR2 That Can Inhibit Angiogenesis and Tumor Growth

Vascular endothelial growth factor receptor 2 (VEGFR2/KDR) plays a crucial role in tumor-associated angiogenesis and vascularization. It has been established that monoclonal antibodies against VEGFR2 can inhibit angiogenesis. In this study, two naturally processed CD8 T-cell epitopes (VILTNPISM and FSNSTNDILI) were identified from murine KDR. Cytotoxic T lymphocytes targeting endothelial cells could be directly monitored by KDR2 and KDR3 Elispots or major histocompatibility complex class I tetramer staining. Immunization with these two peptides effectively reduced angiogenesis and inhibited tumor growth in mouse models. Thus, vaccination with KDR peptides alone or in combination with other anti-angiogenesis agents may afford a novel immunotherapy for inhibition of tumor growth.
Did Industrialization Destroy Social Capital in Indonesia

This paper examines the effect of industrialization on social capital in Indonesia during 1985 to 1997 using repeated cross-sections of nationally representative surveys. We analyze a rich set of social capital measures including multiple measures of voluntary associational activity, levels of trust and informal cooperation, and family outcomes. There are three main findings. First, districts that experienced rapid industrialization showed significant increases in most social capital measures. Second, districts that neighbor rapidly industrializing areas exhibited high rates of out-migration, significantly fewer community credit cooperatives, and a reduction in "mutual cooperation" as assessed by village elders. Finally, initial social capital in a district did not predict subsequent industrial development. We present a model of social capital investment and migration consistent with these patterns. The empirical findings challenge existing results in the social capital literature, and may have implications for social instability in Indonesia since 1997.
The halophilic alkalithermophile Natranaerobius thermophilus adapts to multiple environmental extremes using a large repertoire of Na+(K+)/H+ antiporters

Natranaerobius thermophilus is an unusual extremophile because it is halophilic, alkaliphilic and thermophilic, growing optimally at 3.5 M Na+, pH55°C 9.5 and 53°C. Mechanisms enabling this tripartite lifestyle are essential for understanding how microorganisms grow under inhospitable conditions, but remain unknown, particularly in extremophiles growing under multiple extremes. We report on the response of N. thermophilus to external pH at high salt and elevated temperature and identify mechanisms responsible for this adaptation. N. thermophilus exhibited cytoplasm acidification, maintaining an unanticipated transmembrane pH gradient of 1 unit over the entire extracellular pH range for growth. N. thermophilus uses two distinct mechanisms for cytoplasm acidification. At extracellular pH values at and below the optimum, N. thermophilus utilizes at least eight electrogenic Na+(K+)/H+ antiporters for cytoplasm acidification. Characterization of these antiporters in antiporter‐deficient Escherichia coli KNabc showed overlapping pH profiles (pH 7.8–10.0) and Na+ concentrations for activity (K0.5 values 1.0–4.4 mM), properties that correlate with intracellular conditions of N. thermophilus. As the extracellular pH increases beyond the optimum, electrogenic antiport activity ceases, and cytoplasm acidification is achieved by energy‐independent physiochemical effects (cytoplasmic buffering) potentially mediated by an acidic proteome. The combination of these strategies allows N. thermophilus to grow over a range of extracellular pH and Na+ concentrations and protect biomolecules under multiple extreme conditions.
Temperature dependence of yields of secondary organic aerosols from the ozonolysis of α -pinene and limonene

Abstract. Secondary organic aerosol (SOA) formation has been investigated as a function of temperature and humidity for the ozone-initiated reaction of the two monoterpenes α-pinene (243–313 K) and limonene (253–313 K) using the 84.5 m3 aerosol chamber AIDA. This paper gives an overview of the measurements done and presents parameters specifically useful for aerosol yield calculations. The ozonolysis reaction, selected oxidation products and subsequent aerosol formation were followed using several analytical techniques for both gas and condensed phase characterisation. The effective densities of the SOA were determined by comparing mass and volume size distributions to (1.25±0.10) g cm−3 for α-pinene and (1.3±0.2) g cm−3 for limonene. The detailed aerosol dynamics code COSIMA-SOA proved to be essential for a comprehensive evaluation of the experimental results and for providing parameterisations directly applicable within atmospheric models. The COSIMA-assisted analysis succeeded to reproduce the observed time evolutions of SOA total mass, number and size distributions by adjusting the following properties of two oxidation product proxies: individual yield parameters (αi), partitioning coefficients (Ki), vapour pressures (pi) and effective accommodation coefficients (γi). For these properties temperature dependences were derived and parameterised. Vapour pressures and partitioning coefficients followed classical Clausius – Clapeyron temperature dependences. From this relationship enthalpies of vaporisation were derived for the two more and less volatile product proxies of α-pinene: (59±8) kJ mol−1 and (24±9) kJ mol−1, and limonene: (55±14) kJ mol−1 and (25±12) kJ mol−1. The more volatile proxy components had a notably low enthalpy of vaporisation while the less volatile proxy components gave enthalpies of vaporisation comparable with those of typical products from α-pinene oxidation, e.g. pinonaldehyde and pinonic acid.
Downregulation of Endocardial Nitric Oxide Synthase Expression and Nitric Oxide Production in Atrial Fibrillation: Potential Mechanisms for Atrial Thrombosis and Stroke

Background—In the arterial endothelium, laminar flow and cyclical stretch induce expression of NO synthase (NOS). We hypothesized that atrial fibrillation (AF) causes a downregulation of atrial endocardial NOS expression and NO·production. Because NO·has antithrombotic properties, this may contribute to thromboembolism in AF. Methods and Results—In pigs, AF was produced with rapid atrial pacing at 600 bpm for 1 week, whereas controls had atrial pacing at 100 bpm. All animals had catheter ablation of the AV junction and ventricular pacing at 100 bpm. NO·production from freshly isolated tissue was measured by a NO·-specific microelectrode. Left atrial basal and stimulated NO·production was decreased in AF by 73% and 71% (P <0.01). Endocardial NOS expression, determined by Western analysis, was also significantly decreased by 46%. Expression of the prothombotic protein plasminogen activator inhibitor 1 (PAI-1) is known to be regulated by NO·and was increased in the left atrium by 1.8-fold in AF (P <0.05). NO·concentration was decreased in the left atrial appendage, although NOS expression was not affected. Neither NOS concentration, NO·levels, nor PAI-1 expression were altered in the aortas or right atria of animals with AF. Conclusions—AF is associated with a marked decrease in endocardial NOS expression and NO·bioavailability and an increase in PAI-1 expression in the left atrium. These data suggest that organized atrial contraction is needed to maintain normal endocardial expression of NOS. It is likely that loss of this antithrombotic enzyme contributes to the thromboembolic phenomena commonly observed in AF.
Language research and language community change: Italian Sign Language 1981–2013

Abstract By providing evidence that sign language is an autonomous language, research has contributed to various changes both within and beyond the signing communities. The aim of this article is to show an example of how sign language change is driven not only by language internal factors but also by changes in language perception, as well as in the changing groups of users and the contexts of use. Drawing from data collected at a sign language research centre in Italy on Italian Sign Language during a time span of over thirty years, the present study will show how language research was a major impetus for a new linguistic awareness and changes in language attitude has influenced new linguistic practices and has forced Italian signers to think about rules governing the use of their language.
The Experience of Time, Pleasure, and Interest during Aesthetic Episodes

This study examined time estimations as well as ratings of pleasure and interest for aesthetic episodes varying in duration. It was hypothesized that judgments of exposure duration would reflect the amount of perceptual/cognitive effort needed to appreciate a painting. Effortful processing would lead to overestimation of duration, and automatic or overlearned analysis would produce underestimation. The experiment also examined changes in aesthetic pleasure and interest as a function of exposure duration and stylistic properties of the paintings. Sixteen trained and sixteen naive subjects, including equal numbers of males and females, viewed two sets of paintings varying in collative and stylistic properties for 18, 36 and 72 seconds. The Collative Set of twelve paintings represented two dimensions, Uncertainty and Arousal potential. The Stylistic Set of twelve paintings comprised two dimensions, Representational—Abstract and Linear (hard edge)—Painterly (soft edge). The results for judgment of duration supported the hypothesis. Trained subjects, who possess a repertoire of skills for appreciating paintings, generally underestimated exposure duration. Naive subjects, for whom art appreciation represents an effortful challenge, overestimated duration, especially for the complex paintings. In addition, naive males and females showed opposite monotonic changes in pleasure ratings for the Stylistic Set of paintings. These findings were interpreted in the context of a theory about sex differences in perceptual style.
