Blue Blood and Smooth Skin : Interdependent Relationships Between Feminine Hygiene Product Commercials, Feminism, and Women’s Self-Esteem

Tilborghs, Dionne, Lotz, Nina January 2022 (has links)
The portrayal of women in commercials is intertwined with patriarchal structures and power hierarchies found in Western contemporary society, which stem from the Judeo-Christian binary of a ‘clean/messy’ body as introduced by St. Augustine (354 – 430 CE). This portrayal of women and its effect on their self-esteem, as well as consumerism, have considerable implications for the gender dynamics in modern Western societies. Therefore, the aim of this thesis is to explore the interdependent relationship between feminine hygiene product commercials, feminist movements and women’s self-esteem.  The goal of this thesis is twofold. First, a multimodal discourse analysis of four advertisements from Always and Venus will be performed to uncover to what extent feminine hygiene product commercials are adjusting their portrayal of the female body according to feminist movements. Secondly, four qualitative semi-structured interviews will be conducted to examine how the portrayal of women in these commercials affect women’s self-esteem. This thesis’ research draws from feminist theories, Representation Theory, Consumer Culture Theory (CCT), and the Hierarchy of Effects Theory (HET).  The findings of the analysis imply that the companies have made some adjustments in the way they are portraying women in accordance with the feminist movements. However, both the analysis of the commercials and the interviews imply that more improvements are necessary. The thesis comes to the conclusion that feminine hygiene product commercials can affect the self-esteem of women by creating (unrealistic) norms about how a female body should look and function.

Hollow fiber liquid-phase microextraction in the determination of pharmaceuticals and personal care products

Sagristà i Puig, Ester 23 November 2012 (has links)
Extensive amounts of pharmaceuticals and personal care products (organic emerging pollutants) are introduced into the environment mainly through wastewater treatment plants discharges either effluent wastewater reaching into the aquatic environment or sewage sludge which is spread onto agricultural land. These compounds are not regulated and their negative effects on humans and wildlife are unknown. One of the main challenges of analytical chemistry is to develop selective and sensitive methods for the detection and quantitation of pharmaceuticals and personal care products and their transformation products in complex matrices. The research presented in the thesis is focused on the development of new methods based on the use of hollow fiber liquid- phase microextraction (HF-LPME) technique and liquid chromatography for the determination of some of the most consume pharmaceuticals and personal care products in wastewaters, environmental waters and sewage sludge. / Tones de substàncies biològicament actives són alliberades contínuament al medi ambient, a través de la descàrrega d’aigües residuals als medis aquàtics o de biosòlids en l’agricultura. La presència d’aquestes substàncies (contaminants emergents) en el medi ambient ha generat una gran preocupació perquè es desconeix com actuen i quins són els mecanismes implicats en la seva transformació i/o transport. Un dels reptes de la química analítica és dissenyar mètodes selectius i sensibles per a la determinació de contaminants emergents en matrius complexes. La recerca presentada en aquesta tesi es centra en el desenvolupament de nous mètodes analítics basats en l’ús de la microextracció enfase líquida amb fibra buida (HF-LPME) i la cromatografia líquida per a la determinació d’alguns fàrmacs i productes d’higiene personal en aigües residuals, medis aquàtics i biosòlids.

The effects of triclosan, 2,4-D, and their by-products on the adrenocortical cells of rainbow trout

Dann, Andrea B January 2011 (has links)
The ubiquitous presence of anthropogenic chemicals and their transformation products in surface water represents a toxicological concern from both an ecological standpoint and a human perspective as many of these chemicals are capable of altering hormonal function. Endocrine disrupting compounds can be traced back to numerous sources and may fall under the class of pesticide, industrial chemical, pharmaceutical, personal care product, and/or heavy metals. The adrenal gland is the most common target for endocrine disruptors, although in comparison to the sex steroids, this system has received much less attention in published research. Corticosteroids play a pivotal role in many physiological processes, including immunity, cognitive function, growth, metabolism, reproduction, mineral balance, and blood pressure. A primary cell culture of rainbow trout adrenocortical cells was used to investigate the endocrine disrupting activity of two commonly detected water-borne toxicants, a personal care product, triclosan (TCS), a pesticide, dichlorophenoxyacetic acid (2,4-D), and their transformation products, methyl-triclosan (M-TCS) and dichlorophenol (DCP). Previously, it has been shown that TCS, 2,4-D, and DCP exhibit a potential for endocrine disruption, although it is currently unknown if these chemicals are capable of affecting corticosteroid balance. In this study, all four chemicals showed significant inhibitory effects on corticosteroid synthesis, even though there were considerable differences in their activity. The chemical that exhibited the highest toxicity was 2,4-D, followed by TCS, DCP, and M-TCS. Both parent-compounds proved to be more toxic than their degradation products. More research with suitable test systems is needed to determine the mechanism(s) of action of these corticosteroid disruptors and the health risk that they may present. / ix, 139 leaves : ill. ; 29 cm

No. of bitstreams: 1 Dissertacao de CHIARA MUSSO RIBEIRO DE OLIVEIRA SOUZA.pdf: 3219731 bytes, checksum: 4e9cda14fdff3b61520c40dd1db90c92 (MD5) Previous issue date: 2009-02-27 / A saúde vaginal depende de complexas interações entre a microbiota vaginal, a histofisiologia da mucosa escamosa, o estado hormonal e os mecanismos de defesa do hospedeiro. Muitos fatores podem alterar essas relações, induzindo citólise, infecção e inflamação, genericamente denominados infecção vaginal (IV). A IV manifesta-se por graus e combinações variáveis de ardor, prurido, dispareunia, disúria, mau odor e aumento e modificações do conteúdo vaginal. A abordagem clínica tem sido orientada apenas empiricamente e há pouca percepção do risco potencial das IV. Isso se deve a vários fatores, incluindo uma complexa rede de causas, inespecificidade das manifestações, discordâncias conceituais, dificuldade diagnóstica, natureza íntima da prática sexual e limitados recursos diagnósticos e terapêuticos. Objetivos: Avaliar em nosso meio o uso dos intrumentos autocoleta do conteúdo vaginal, diário de hábitos, sintomas e práticas sexuais e descrever as variações diárias da microbiota, da citólise, do exsudato inflamatório e dos sintomas. Casuística: 18 mulheres no menacme, não grávidas, recrutadas em clínicas ecológicas na região metropolitana de Vitória, ES. Métodos: Estudo descritivo com exame ginecológico inicial, registro diário de hábitos de vestuário, higiene, práticas sexuais e sintomas e autocoleta vaginal por um mínimo de trinta dias. Os esfregaços vaginais foram examinados (Gram e Papanicolaou), sumarizando-se os achados como grau lactobacilar, candidíase, citólise e inflamação. Os achados históricos, do exame ginecológico e do estudo seqüencial foram registrados em um quadro pictórico individual e sumarizados por freqüência simples. Resultados: A mediana dos dias com respostas às perguntas do diário foi maior que 87% em todas as participantes. A autocoleta do conteúdo vaginal garantiu espécimes adequados em mais de 85% dos dias em todas as participantes. Microbiota bacteriana anormal, candidíase, citólise e inflamação foram observadas em 27,8%, 50,0%, 83,3% e 94,4% das participantes em algum momento durante o estudo. Os hábitos de vestuário, higiene, e práticas sexuais e os sintomas, microbiota, citólise e inflamação variaram marcadamente tanto entre as mulheres como ao longo dos dias em uma mesma mulher. Conclusão: O registro diário e a autocoleta foram bem aceitos e garantiram dados e espécimes adequados que, sumarizados em um quadro pictórico, mostram que há marcadas variações diárias entre os elementos das redes de causas e efeitos de IV, indicando que somente com estudos seqüenciais é possível identificar todo o espectro das IV. / Vaginal health depends on complex interactions between the vaginal microbiota, the squamous mucosa histophysiology, hormonal status and host defense mechanisms. Several factors can alter these relationships, inducing cytolisis, infection and inflammation, generally named vaginal infection (VI). VI manifests itself by changeable degrees and combinations of burning, itching, dispareunia, disuria, offensive odour and increase and change of the vaginal content. The clinical approach has been taken only empirically and there is few perception of the potential risk of VI. This is due to several factors, including a complex net of causes, few specific manifestations, concept disagreements, difficulties on diagnostic approach, intimate nature of sexual practices and limited diagnostic and therapeutic resources. Objective: To evaluate in our environment the use of the following tools: self collect of the vaginal content and diary of habits, symptoms and sexual practices and to describe the diary changes of the microbiota, cytolisis, inflammatory exsudate and symptoms. Casuistic: 18 non pregnant women during menacme, enlisted at gynecological offices in metropolitan region of Vitória, ES. Study design: Descriptive study consisted of an initial clinical evaluation, daily register of clothing, hygiene, sexual practices and symptoms and self collect of vaginal content by at least 30 days. The vaginal smears were evaluated (Gram and Papanicolaou) and the findings were summarized as lactobacillary grade, candidiasis, cytolisis and inflammation. The historical, gynecological and sequential findings were registered on an individual pictorial table and were summarized by simple frequency. Results: The median of days with diary answers replys was higher than 87% in all of the participants. The self collect of the vaginal content guaranteed adequate smears in more than 85% of the days of the study in all of the participants. Anormal microbiota, candidiasis, cytolisis and inflammation were observed in 27,8%, 50%, 83,3% and 94% of the participants in any moment during the study period. The clothing and hygiene habits, sexual practices, symptoms, anormal bacterial microbiota, candidiasis, cytolisis and inflammation varied markedly between the participants and across the days in a single woman. Conclusion: The daily register and the self collect were well accepted and guaranteed adequate data and smears which, summarized on an individual pictorial table, show that there are marked daily variation between the elements of the nets of causes and effects of the VI, indicating that only sequential studies allow the identification of the whole VI spectre.
