This dissertation questions and expands currently held notions of traditional fashion identities in South African fashion photography. The impetus for this study stems from observations of a relatively low level of political engagement in local fashion photography as compared to other areas of art and design which seem very enunciative of a politics of identity. Investigation of identity politics in South African fashion photography was informed by a staged investigation. Firstly, accounts of a literature review of fashion theory and key theories of identity allow entrenched constructions of fashion representations to be seen as restrictively politicised. Primary investigation of expert fashion views followed. The concepts of hybridity and fluidity in theories of identity were central to the discovery of alternative politicised fashion identities

AbstractMuscle injuries are frequent, both in the practice of exercises and in the work environment, and after the injury, healing begins. The inflammatory phase of muscle healing is accompanied by an increase in the production of reactive oxygen species (ROS), and a reduction in the antioxidant activity of defense enzymes. This imbalance between both can generate oxidative stress, which can cause oxidative damage by directly affecting vital cellular constituents, such as lipids, proteins and DNA, in addition to interfering negatively in the muscle cells differentiation . Therefore, substances or therapies that stimulate antioxidant repair and defense are crucial to keep the levels of free radical production low, and to minimize factors that delay or prevent tissue recovery, among these therapies photo biomodulation has stood out. The objective of this literature review is to clarify the FBM effect on oxidative stress and muscle repair. Therefore, a search was carried out in the databases of Pubmed, Scielo, Lilacs and PEDro, using the keywords “Photo biomodulation”, “low power laser”, “muscle repair”, “oxidative stress”, and in English were ”Photo biomodulation”, “low level laser therapy”, “muscle repair” and “oxidative stress”. The texts that addressed the research topic, published between 2000 and 2020, were chosen. After analyzing the articles, it was possible to observe that photo biomodulation, despite presenting a great variety of parameters, moment of application and irradiation protocol found in the literature, shows beneficial results in the repair muscle and in the reduction of oxidative stress and fatigue markers. Keywords: Low-Level Light Therapy. Oxidative Stress. Edema. ResumoLesões musculares são frequentes, tanto na prática de exercícios como no ambiente de trabalho, sendo que após a lesão, inicia a cicatrização. A fase inflamatória da cicatrização muscular é acompanhada do aumento da produção de espécies reativas de oxigênio (ERO) e uma redução da atividade antioxidante das enzimas de defesa. Este desequilíbrio entre ambos pode gerar o estresse oxidativo, que leva a danos e atingi diretamente constituintes celulares vitais, como lipídios, proteínas e DNA, além de interferir negativamente na diferenciação das células musculares. Portanto, substâncias ou terapias que estimulem a reparação e a defesa antioxidante são cruciais para manter os níveis de produção de radicais livres baixos, e minimizar os fatores que atrasam ou impedem a recuperação do tecido, dentre estas terapias a fotobiomodulação tem se destacado. O objetivo da presente revisão de literatura é esclarecer o efeito da FBM sobre o estresse oxidativo e o reparo muscular. Sendo assim, realizou-se uma pesquisa nas bases de dados da Pubmed, Scielo, Lilacs e PEDro, utilizando as palavras-chave “Fotobiomodulação”, “laser de baixa potência”, “reparo muscular”, “estresse oxidativo”, e em inglês foram “photobiomodulation”, “low level laser therapy”, “muscle repair” e “oxidative stress”. Foram escolhidos os textos que abordavam o tema da pesquisa, publicados entre 2000 e 2020. Analisando os artigos foi possível observar que a fotobiomodulação apesar de apresentar grande variedade de parâmetros, momento de aplicação e protocolo de irradiação encontrados na literatura, mostra resultados benéficos no reparo muscular e na diminuição de marcadores do estresse oxidativo e fadiga. Palavras-chave: Terapia com Luz de Baixa Intensidade. Estresse Oxidativo. Edema.

The literature review is an important part of an academic text. It is common for students to learn literature review writing through reading and practice. This study explored peer feedback as an assisting interactive social tool that aims to provide formative assessment of literature reviews written by master students. The student reviewers’ feedback characteristics were identified and coded, and their relationships with writing performance were examined. Six assessment criteria and writing categories relevant to the literature reviews genre were employed for the writing process as well as a peer feedback process. The feedback patterns were analysed according to four dimensions: describing status or problems versus prescribing directions, abundant input versus uncritical/empty comments, high versus low level, and constructive versus negative. No correlations were found between review patterns, students’ performance mark, and quantity of feedback received. Significant correlations were observed between specific review patterns and separate category scores. The dimensions constructive vs. negative and high vs. low level correlated with most category scores. The findings show that the students were able to provide useful and high-level comments to assist their peers’ writing. Overall, it was found that peer feedback quality and quantity do not define the performance mark, but benefit individual aspects of literature reviews writing.

The purpose of the article is to examine the impact of leverage on the market valuation of companies. The article verifies two hypotheses: 1. the degree of leverage is an important factor that impacts the market valuation of companies; 2. for companies with a high level of leverage, the impact of this leverage on their valuation is negative, and for companies with a low level of leverage, the impact is positive.The methodology of the study includes a critical literature review and empirical research based on correlation and regression analysis, including univariate and multivariate regression. The analysis covered quarterly data of ten energy companies listed on the Warsaw Stock Exchange. An important component of the research was classifying those companies into several groups, depending on their level of debt ratio in relation to the industry median debt ratio.The results of the research: The literature review did not provide an unequivocal conclusion to the problem. The empirical analysis did not give grounds to reject the first hypothesis; however, the second one was rejected. The research showed positive correlation and regression coefficients between the debt ratio and the price to book value ratio for highly leveraged companies and negative ones for companies with a low level of debt. The results are surprisingly contrary to the expectations based on theoretical premises.
