International Sensations : Representationen av nationalitet i World Wrestling Entertainment

Denna uppsats intresserar sig för professional wrestling och då specifikt bolaget World Wrestling Entertainment, WWE. Syftet med uppsatsen är att undersöka hur nationalitet representeras i World Wrestling Entertainments produkt. Uppsatsens teoretiska ramverk består utav tre olika författare. Dessa tre är Michael Billig, Stuart Hall och Roland Barthes. Från Michael Billig används begreppen 'hot and banal nationalism' för att definiera nationalism. Från Stuart Hall hämtas teorier om 'representation', vad det är och hur det fungerar samt olika perspektiv på varför det är intressant att studera 'olikhet'. Slutligen använder sig uppsatsen utav Roland Barthes artikel Le monde où l'on catche, the World of Wrestling i den engelska översättningen, som analyserar wrestling på ett semiotiskt vis. Många av de teorier som Barthes presenterar i denna artikel är relevanta än idag trots att han skrev artikeln på 1950-talet. Uppsatsens frågeställning kommer att undersökas genom en multimodal analys. En multimodal analys lämpar sig väl för ett så visuellt fenomen som wrestling. Det möjliggör även för studier av de rent textuella elementen i programmen och inte bara det visuella. Materialet består utav de inledande videomontagen från två olika wrestlingmatcher. Båda matcherna är hämtade från WWEs största årliga pay-per-view Wrestlemania som gått av stapeln varje år sedan år 1985. Den ena matchen är hämtad från Wrestlemania 29 år 2013 och den andra är hämtad från Wrestlemania 31 år 2015. Båda matcherna inkluderar icke-amerikanska karaktärer. Den första matchen ser amerikanen Jack Swagger möta mexikanen Alberto Del Rio och den andra matchen ser amerikanen John Cena möta den ryske Rusev. Efter analysen kunde slutsatsen dras att vad gällde de matcher som analyserats framställdes de ickeamerikanska karaktärerna varken positivt eller negativt. Vad analysen lyckades komma fram till var att de icke-amerikanska karaktärerna var där för att reproducera en bild av den amerikanska nationella identiteten och att de icke-amerikanska karaktärernas nationaliteter egentligen inte var relevanta. Det relevanta var det faktum att de var just icke-amerikaner. Deras faktiska nationaliteter behandlades inte i någon större utsträckning i materialet. Materialet verkade mest kretsa kring USA och dess nationella identitet.

Acerca de la Tesis "Del Día del Petróleo Nacional al Día Nacional del Petróleo en propagandas y publicidades gráficas comodorenses de YPF"

El artículo presentará resultados obtenidos en una Tesis de Grado de la Licenciatura en Comunicación Social de la Facultad de Humanidades y Ciencias Sociales de la Universidad Nacional de la Patagonia San Juan Bosco. En ese trabajo, un análisis de imagen y discurso, nos propusimos estudiar comparativamente los discursos publicitarios que YPF emitió antes y después de ser privatizada. La conmemoración del 13 de diciembre, aniversario del descubrimiento del petróleo en el país (ocurrido en Comodoro Rivadavia), fue tomada como referencia. Nos preguntamos, entre otras cosas, cómo conciben Yacimientos Petrolíferos Fiscales (YPF) y Repsol a sus objetivos empresariales en relación al recurso y su vinculación con el desarrollo nacional. Por medio de lecturas de segundo orden que problematizan las relaciones entre significantes y significados que se nos imponen a través de procesos hegemónicos, deconstruimos veinticinco propagandas y publicidades publicadas en la prensa gráfica local entre 1943 y 2007. Cada mensaje fue entendido como un texto multimodal; y sus contextos de emisión, las estructuras internas de las imágenes y los mensajes propuestos nos interesaron especialmente. Nuestra mirada dio algunos sentidos posibles a las imágenes ypefianas, en un intento de "desmitificar" los avisos y deconstruirlos para luego "volver a armarlos"

Differences in analgesia in opioid naïve and tolerant patients with sciatic nerve blockade following elective foot and ankle surgery

1.1 Introduction and Purpose: Adequate postoperative analgesia in the opioid tolerant with chronic non-malignant pain is challenging. Multimodal pain relief regimens include regional anesthesia but opioid tolerant patients report increased postoperative pain and opioid consumption. This study compared analgesia in opioid naïve and tolerant patients receiving postoperative sciatic nerve blockade for foot and ankle surgery. 1.2 Method: Preoperative pain scores, trauma, maintenance and intraoperative opioid doses and following postoperative sciatic nerve blockade, patient self-reported pain scores and opioid consumption at discharge from the post-anesthesia unit and 24 hours were recorded. 1.3 Results: 191 patients enrolled. 40.3% were opioid tolerant and 33% had lower extremity trauma. Preoperative, immediate and delayed postoperative pain scores and intraoperative, immediate and 24 hour postoperative consumption of opioids were increased in opioid tolerant patients. Trauma and continuous infusion in opioid naïve and tolerant groups did not result in differences in 24 hour opioid consumption. 1.4 Limitations: Small subgroups and use of the pain score limited the accuracy of results. 1.5 Conclusion: Opioid tolerant patients require greater analgesic doses following sciatic nerve blockade for foot and ankle surgery. 24 hour opioid consumption for opioid naïve and tolerant patients is neither influenced by lower extremity injury nor continuous infusion.

Prolonged Duration of Sciatic Nerve Blockade in the Elderly after Foot and Ankle Surgery

1.1 Background and Objectives: Perioperative morbidity related to anesthesia renders elderly patients vulnerable because age related factors affect medication effects, clearance and metabolism. Regional anesthesia within a multimodal regimen reduces opioid adverse effects in the elderly and improves immediate analgesia but not long term recovery and prolonged nerve blockade has been reported. The purpose of this study was to assess analgesic effects of sciatic nerve blockade in the elderly. 1.2 Methods: Postoperative sciatic nerve blockade was administered for foot and ankle surgery to patients over age 18 years. Preoperative, post-anesthesia unit and 24 hour postoperative pain scores and opioid doses for these same intervals were recorded. 1.3 Results: 47 patients enrolled and 12 (25.5%) were over age 70. Preoperative, immediate and 24 post-operative pain scores and total intraoperative and immediate postoperative opioid doses were lower in the elderly. The total 24 hour postoperative opioid doses in the elderly were lower compared to the younger group. 1.4 Conclusions: Total 24 hour postoperative cumulative opioid doses after sciatic nerve blockade in patients over 70 are lower than in younger patients. Further observations in greater numbers of patients and improved ultrasound to assess sciatic nerve structure in the elderly are warranted to study this effect.

Analysis of the phase behavior of the aqueous poly(ethylene glycol)-Ficoll system

The PEG-Ficoll polymer phase system is one that has been overlooked in the past for biotechnology applications because of the stability of its emulsions. However, new applications, such as emulsion coating of cells, are appearing that rely on this very property. Ficoll is highly polydisperse and multimodal with three distinct Ficoll peaks in gel permeation chromatography. As a result, the transition between one-phase and two-phase systems is blurred and the binodials obtained through turbidometric titration and tie-line analysis differ significantly. Moreover, since the three Ficoll peaks partition differently, tie-line analysis cannot be described by a simple model of the aqueous two-phase system. A simple modification to the model allowed for excellent fit, and this modification may prove well-suited for the many practical cases where aqueous two-phase systems fail to display parallel tie-lines as implicitly assumed in the simpler model.

Modeling of optical detection of spin-polarized carrier injection into light-emitting devices

We investigate the emission of multimodal polarized light from light emitting devices due to spin-aligned carrier injection. The results are derived through operator Langevin equations, which include thermal and carrier-injection fluctuations, as well as nonradiative recombination and electronic g-factor temperature dependence. We study the dynamics of the optoelectronic processes and show how the temperature-dependent g factor and magnetic field affect the degree of polarization of the emitted light. In addition, at high temperatures, thermal fluctuation reduces the efficiency of the optoelectronic detection method for measuring the degree of spin polarization of carrier injection into nonmagnetic semicondutors.

Central hypersensitivity in whiplash: Implications for physiotherapy assessment and management

It is emerging that whiplash-associated disorder (WAD) is a complex condition characterised by a variety of physical and psychological features. Generalised sensory hypersensitivity is one of these features and its presence reflects augmented central pain processing mechanisms. Whilst most studies have investigated these processes in chronic WAD, it is becoming clear that in some of the whiplash injured, sensory disturbances are present from soon after injury, and are associated with both poor recovery and recalcitrance to multimodal physiotherapy interventions. Evidence for sensory hypersensitivity in WAD and possible underlying mechanisms of these phenomena are reviewed. Physiotherapists play an important role in the evaluation and management of whiplash injury. It is important that sensory disturbances be identified early in the clinical assessment of the whiplash injured patient and that ensuing management strategies address these changes, if the aim of treatment is to prevent the transition to chronicity.

Modeling diffraction and imaging of laser beams by the mode-expansion method

We present a new method of modeling imaging of laser beams in the presence of diffraction. Our method is based on the concept of first orthogonally expanding the resultant diffraction field (that would have otherwise been obtained by the laborious application of the Huygens diffraction principle) and then representing it by an effective multimodal laser beam with different beam parameters. We show not only that the process of obtaining the new beam parameters is straightforward but also that it permits a different interpretation of the diffraction-caused focal shift in laser beams. All of the criteria that we have used to determine the minimum number of higher-order modes needed to accurately represent the diffraction field show that the mode-expansion method is numerically efficient. Finally, the characteristics of the mode-expansion method are such that it allows modeling of a vast array of diffraction problems, regardless of the characteristics of the incident laser beam, the diffracting element, or the observation plane.

Analysis of the effect of transverse modes on free-space optical interconnect performance

Vertical-cavity surface-emitting lasers (VCSELs) and microlenses can be used to implement free space optical interconnects (FSOIs) which do not suffer from the bandwidth limitations inherent in metallic interconnects. A comprehensive link equation describing the effects of both optical and electrical noise is introduced. We have evaluated FSOI performance by examining the following metrics: the space-bandwidth product (SBP), describing the density of channels and aggregate bandwidth that can be achieved, and the carrier-to-noise ratio (CNR), which represents the relative strength of the carrier signal. The mode expansion method (MEM) was used to account for the primary cause of optical noise: laser beam diffraction. While the literature commonly assumes an ideal single-mode laser beam, we consider the experimentally determined multimodal structure of a VCSEL beam in our calculations. It was found that maximum achievable interconnect length and density for a given CNR was significantly reduced when the higher order transverse modes were present in Simulations. However, the Simulations demonstrate that free-space optical interconnects are still a suitable solution for the communications bottleneck, despite the adverse effects introduced by transverse modes.

A mathematical modelling technique for the analysis of the dynamics of a simple continuous EDA

This paper presents some initial attempts to mathematically model the dynamics of a continuous estimation of distribution algorithm (EDA) based on a Gaussian distribution and truncation selection. Case studies are conducted on both unimodal and multimodal problems to highlight the effectiveness of the proposed technique and explore some important properties of the EDA. With some general assumptions, we show that, for ID unimodal problems and with the (mu, lambda) scheme: (1). The behaviour of the EDA is dependent only on the general shape of the test function, rather than its specific form; (2). When initialized far from the global optimum, the EDA has a tendency to converge prematurely; (3). Given a certain selection pressure, there is a unique value for the proposed amplification parameter that could help the EDA achieve desirable performance; for ID multimodal problems: (1). The EDA could get stuck with the (mu, lambda) scheme; (2). The EDA will never get stuck with the (mu, lambda) scheme.

Bayesian analysis of the scatterometer wind retrieval inverse problem:Some new approaches

The retrieval of wind vectors from satellite scatterometer observations is a non-linear inverse problem. A common approach to solving inverse problems is to adopt a Bayesian framework and to infer the posterior distribution of the parameters of interest given the observations by using a likelihood model relating the observations to the parameters, and a prior distribution over the parameters. We show how Gaussian process priors can be used efficiently with a variety of likelihood models, using local forward (observation) models and direct inverse models for the scatterometer. We present an enhanced Markov chain Monte Carlo method to sample from the resulting multimodal posterior distribution. We go on to show how the computational complexity of the inference can be controlled by using a sparse, sequential Bayes algorithm for estimation with Gaussian processes. This helps to overcome the most serious barrier to the use of probabilistic, Gaussian process methods in remote sensing inverse problems, which is the prohibitively large size of the data sets. We contrast the sampling results with the approximations that are found by using the sparse, sequential Bayes algorithm.

Variational inference for diffusion processes

Diffusion processes are a family of continuous-time continuous-state stochastic processes that are in general only partially observed. The joint estimation of the forcing parameters and the system noise (volatility) in these dynamical systems is a crucial, but non-trivial task, especially when the system is nonlinear and multimodal. We propose a variational treatment of diffusion processes, which allows us to compute type II maximum likelihood estimates of the parameters by simple gradient techniques and which is computationally less demanding than most MCMC approaches. We also show how a cheap estimate of the posterior over the parameters can be constructed based on the variational free energy.
