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.

Syftet med denna studie är att undersöka hur konstruktionen av ett nationellt identitetsideal sker inom den diskursiva praktik som artiklar och användarkommentarer tillsammans skapar på de invandrings- och mediekritiska nyhetsplattformarna Avpixlat och Nyheter Idag. Vårt huvudsakliga fokus har varit genus och kultursyn, eftersom dessa aspekter utgör en grundläggande del av identitetskonstruktionen. Kathryn Woodward (1997) menar att all identitetskonstruktion sker genom simultana processer av inkludering och exkludering. Genom att exkludera ‘de Andra’ från ett föreställt ‘vi’ erbjuds möjligheten att avgränsa vad ‘vi’ inte är och på så sätt undvika att uttryckligen fastslå vad ‘vi’ är. På detta sätt kan inre motsättningar eller självmotsägelser döljas och ignoreras. Detta blir särskilt aktuellt då den rådande flyktingkrisen medför att människor tvingas lämna sina hemländer för att på obestämd tid befinna sig inom andra nationella gemenskaper. Vilket i sin tur aktualiserar frågan kring medborgarskap samt vem som betraktas som svensk och inte. Vi kommer därför att använda oss av teorier kring hur nationalism och nationell identitet skapas, vilken roll genus fyller i denna process samt hur vi kan förstå den kultursyn som uttrycks av artiklar och i användarkommentarerna. I analysen har vi använt oss av en kritisk diskursanalys enligt Faircloughs modell. Han menar att språket är simultant konstruerat och konstruerande, men även att språket innehåller möjligheter att skapa omedvetna maktstrukturer i den språkliga praktiken, vilka kan dölja ideologiska förtecken samt rådande maktförhållanden. Metoden avser därför att avtäcka dessa strukturer. Detta sker genom analys av texter på tre nivåer: text, diskursiv praktik samt social praktik.Utifrån vår analys menar vi därför att användarkommentarerna använder sig av en kultursyn från globaliseringsparadigmet clash of civilizations i kombination med ett orientalistiskt synsätt, för att konstruera ett imaginärt nationellt identitetsideal. Genom att producera de binära oppositionerna 'vi svenskar' och 'de Andra' möjliggörs en identifikation i negation till 'de Andras' tillskrivna och oönskade egenskaper. Genus fyller vidare en tveeggad roll i denna konstruktion. Å ena sidan gestaltas kvinnor enbart som objekt för kvinnosyn: 'vår' jämställdhet och 'våra' goda jämställda män i konstrast mot 'Andras' förlegade och förtryckande kvinnosyn. 'Deras' kvinnosyn riskerar även att gå ut över 'våra' kvinnor och placera dem under samma förtryck som 'Andra' kvinnor upplever. Å andra sidan möjliggörs genuskonstruktionen av mannen som nationens beskyddare, där kvinnor 'är' nationen medan män 'gör' nationen. Mannen framställs här som det aktiva subjektet, vars ansvar är att beskydda nationen från såväl inre som yttre hot. Vidare menar vi att det finns ett tydligt maskulinitetsideal, där jämställdhet utgör den främsta markören för 'svenska män’ samtidigt som artiklar och användarkommentarer etablerar en negation av ‘de ojämställda Andra’, där män från ‘Andra’ kulturer anses representera en patriarkal och förtryckande struktur.

A identificação dos padrões morfológicos da face é de extrema importância para a elaboração do diagnóstico ortodôntico e conseqüente plano de tratamento. Sendo assim, esta pesquisa teve como objetivo avaliar as relações entre as medidas lineares N-ENA, ENA-Pog e N-Pog, as medidas angulares N.OPI.ENA, ENA.OPI.Pog e N.OPI.Pog, e o índice VERT de acordo com a classificação proposta por RICKETTS. O material de estudo foi constituído de 700 telerradiografias, em norma lateral, de indivíduos brasileiros, leucodermas, de ambos os gêneros (318 do gênero masculino e 382 do gênero feminino), apresentando idade média de 16,66 anos. Das 700 telerradiografias foram constituídos quatro grupos de acordo com a oclusão. O primeiro grupo foi constituído de indivíduos com oclusão normal natural segundo ANDREWS, sendo observadas, clinicamente, quatro das seis chaves de oclusão. Os demais grupos se constituíram de indivíduos com más-oclusões de Classe I, II e III segundo ANGLE, sem relato de tratamento ortodôntico anterior. Após a análise estatística para a avaliação das medidas lineares N-ENA, ENA-Pog e N-Pog, e medidas angulares N.OPI.ENA, ENA.OPI.Pog e N.OPI.Pog, em relação ao índice VERT, evidenciou um aumento progressivo das medidas pesquisadas em relação aos seis padrões faciais determinados pelo índice VERT, mostrando um aumento destas medidas conforme se vai do padrão braquifacial severo para o padrão dolicofacial severo.

O posicionamento da maxila no esqueleto craniofacial tem sido motivo de investigação por diversos autores ao longo do tempo. Traduzindo suas idéias por meio de medidas lineares ou angulares, tais autores definiram o que consideraram como a posição ideal , normal , ou aceitável da maxila, relacionando-a, na maioria das vezes, com a base do crânio. A partir da avaliação de indivíduos com oclusão considerada normal e com bom equilíbrio facial, eram calculados valores médios e desvios-padrão de determinadas medidas, os quais eram tomados como parâmetros para avaliações cefalométricas de pacientes distintos. Diante das divergências de opiniões encontradas na literatura, a proposta do presente estudo foi avaliar o posicionamento da maxila nos sentidos vertical, ântero-posterior e a sua inclinação, numa amostra de 94 indivíduos com oclusão normal. Foram determinadas correlações entre medidas do próprio indivíduo: OPI-N com OPI-ENA e N-ENA com ENA-ENP. A partir dos fortes índices de correlação encontrados, concluiu-se que a medida OPI-N pode ser tomada como referência para determinação de OPI-ENA, da mesma forma que ENA-ENP pode ser considerada para determinação de N-ENA, definindo respectivamente a posição da maxila nos sentidos sagital e vertical. A inclinação da maxila, representada aqui pelo ângulo OPI.ENA.ENP, teve valor médio estatisticamente próximo a 0o (zero), indicando forte tendência do prolongamento posterior do plano palatino (ENA-ENP) tangenciar a base posterior do crânio (ponto OPI), o que se revela uma importante característica de indivíduos com oclusão normal.

The effects of cholinergic agents undergoing clinical trials for the treatment of Alzheimer's disease and the anticholinergic agent scopolamine, were investigated on the components of the flash and pattern reversal visual evoked potentials (VEPs) in young healthy volunteers. The effect of recording the flash and pattern reversal VEPs for 13 hours in 5 healthy male volunteers, revealed no statistically significant change in the latency or amplitude measures. Administration of the muscarinic agonist SDZ 210-086 to 16 healthy male volunteers resulted in the reduction of the flash N2-P2 and pattern reversal N75-P100 peak-to-peak amplitudes. These effects on the flash VEP occurred at both doses (0.5 and 1.0 mg/day), but only at the higher dose on the pattern reversal VEP. Administration of the antimuscarinic agent scopolamine to 11 healthy young male volunteers, resulted in a delay of the flash P2 latency but no effect on the pattern reversal P100 latency. The pattern reversal N75-P100 peak-to-peak amplitude was also increased post dosing. The combination of scopolamine with the acetylcholinesterase inhibitor SDZ ENA 713 resulted in no significant effect on the flash and pattern reversal VEPs, suggesting that the effects of scopolamine may have been partially reversed. Topical application of scopolamine in 6 young healthy volunteers also resulted in no statistically significant effects on the flash and pattern reversal VEPs. The selective effect of scopolamine on the flash P2 latency but not on the pattern reversal P100 latency, provided a model whereby new cholinergic agents developed for the treatment of Alzheimer's disease can be investigated on a physiological basis. In addition, the results of this study led to the hypothesis that the selective flash P2 delay in Alzheimer's disease was probably due to a cholinergic deficit in both the tectal pathway from the retina to the visual cortex and the magnocellular path of the geniculostriate pathway, whereas the lack of an effect on the pattern reversal P100 component was probably due to a sparing of the parvocellular geniculostriate pathway.
A copper-hydrogen peroxide redox system induces dityrosine cross-links and chemokine oligomerisation

The activity of the chemoattractant cytokines, the chemokines, in vivo is enhanced by oligomerisation and aggregation on glycosaminoglycan (GAG), particularly heparan sulphate, side chains of proteoglycans. The chemokine RANTES (CCL5) is a T-lymphocyte and monocyte chemoattractant, which has a minimum tetrameric structure for in vivo activity and a propensity to form higher order oligomers. RANTES is unusual among the chemokines in having five tyrosine residues, an amino acid susceptible to oxidative cross-linking. Using fluorescence emission spectroscopy, Western blot analysis and LCMS-MS, we show that a copper/H2O2 redox system induces the formation of covalent dityrosine cross-links and RANTES oligomerisation with the formation of tetramers, as well as higher order oligomers. Amongst the transition metals tested, namely copper, nickel, mercury, iron and zinc, copper appeared unique in this respect. At high (400 µM) concentrations of H2O2, RANTES monomers, dimers and oligomers are destroyed, but heparan sulphate protects the chemokine from oxidative damage, promoting dityrosine cross-links and multimer formation under oxidative conditions. Low levels of dityrosine cross-links were detected in copper/H2O2-treated IL-8 (CXCL8), which has one tyrosine residue, and none were detected in ENA-78 (CXCL5), which has none. Redox-treated RANTES was fully functional in Boyden chamber assays of T-cell migration and receptor usage on activated T-cells following RANTES oligomerisation was not altered. Our results point to a protective, anti-oxidant, role for heparan sulphate and a previously unrecognised role for copper in chemokine oligomerisation that may offer an explanation for the known anti-inflammatory effect of copper-chelators such as penicillamine and tobramycin.

This dissertation consists of three independent studies, which study the nomological network of cultural intelligence (CI)—a relatively new construct within the fields of cross-cultural psychology and organizational psychology. Since the introduction of this construct, CI now has a generally accepted model comprised of four codependent subfactors. In addition, the focus of preliminary research within the field is on understanding the new construct’s correlates and outcomes. Thus, the goals for this dissertation were (a) to provide an additional evaluation of the factor structure of CI and (b) to examine further the correlates and outcomes that should theoretically be included in its nomological network. Specifically the model tests involved a one-factor, three-factor, and four-factor structure. The examined correlates of CI included the Big Five personality traits, core self-evaluation, social self-efficacy, self-monitoring, emotional intelligence, and cross-cultural experience. The examined outcomes also included overall performance, contextual performance, and cultural adaption in relation to CI. Thus, this dissertation has a series of 20 proposed and statistically evaluated hypotheses. The first study in this dissertation contained the summary of the extant CI literature via meta-analytic techniques. The outcomes of focus were significantly relevant to CI, while the CI correlates had more inconclusive results. The second and third studies contained original data collected from a sample of students and adult workers, respectively. In general, the results between these two studies were parallel. The four-factor structure of CI emerged as the best fit to the data, and several correlates and outcomes indicated significant relation to CI. In addition, the tested incremental validity of CI showed significant results emerging in both studies. Lastly, several exploratory analyses indicated the role of CI as a mediator between relevant antecedent and the outcome of cultural adaption, while the data supported the mediator role of CI. The final chapter includes a thorough discussion of practical implications as well as limitation to the research design.^
