The deletion and overexpression of two esterase genes, IAH1 and TIP1, in Saccharomyces cerevisiae to determine their effects on the aroma and flavour of wine and brandyHignett, Jason Satch 12 1900 (has links)
Thesis (MSc)--University of Stellenbosch, 2002. / ENGLISH ABSTRACT: No single chemical constituent can be accredited with giving wine and brandy their
overall aroma and flavour. The aroma and flavour of wine and brandy are rather
attributed to a number of chemical constituents reacting together and it is these
reactions that give the beverage its character. Certain chemicals within wine and
brandy do, however, make larger contributions to the flavour. These include the
esters, terpenes and volatile acids, although others also exist.
Esters are a large group of volatile compounds with variable aroma and flavour
characteristics, including banana-like (isoamyl acetate), apple-like (ethyl caproate)
and chemical/solvent-like (ethyl acetate). Esters are produced as secondary
metabolites during the conversion of sugar to ethanol and are formed when an
alcohol binds with a fatty acid. Chemically, ester metabolism is well documented and
understood; however, much work still needs to be done on a genetic level. The yeast
strain used during fermentation is one of the most important factors contributing to
the type and quantity of esters produced. This is due to differences in genetic
makeup. The metabolism of esters is controlled largely on a genetic level, with
numerous genes being involved. The alcohol acetyltransferase genes are involved in
ester anabolism, whilst esterase genes are involved in ester catabolism. Esterases
have a negative effect on the overall level of esters within an alcoholic beverage, as
they are capable of reducing the number of esters and are thus capable of altering
the beverage's aroma and flavour profile. The IAH1 and the TIP1 gene products are
believed to encode for two such esterases.
The objective of this study was to investigate the contribution of the IAH1 and
TIP1 genes to the level of esters in both wine and brandy. This was accomplished by
using two approaches. Firstly, the above genes were disrupted using a polymerise
chain reaction (PCR)-generated disruption cassette homologous to either the IAH1 or
the TIP1 gene. These cassettes were integrated into the industrial wine yeast,
Saccharomyces cerevisiae strain VIN13. The integrations were verified by Southern
blot analysis to produce yeasts VIN13-~IAH1 and VIN13-~TIP1; however, only a
single copy of each was disrupted. Secondly, the IAH1 and the TIP1 genes were
cloned from S. cerevisiae using PCR into plasmid pj between the phosphoglycerate
kinase gene (PGK1) promoter and terminator, producing plasmids pJ-IOE1 and
pJ-TOE1. The PGK1 promoter has previously been shown to constitutively express
genes at high levels. These new constructs were then used as template for PCR to
produce two overexpression cassettes, one for IAH1 and the other for TlP1. These
cassettes were integrated into S. cerevisiae VIN13 and verified by Southern blot
analysis to produce strains VIN13-IOE1 and VIN13-TOE1.
The above yeast strains including VIN13 were used for the production of wines
and base wines from Colombard must. Reverse-transcriptase (RT-PCR) confirmed
that the VIN13-IOE1 and VIN13-TOE1 strains overexpressed the appropriate gene at a higher level than the control VIN13 strain. The VIN13-AIAH1 disrupted strain
showed no difference in expression level to that of the control strain, whilst
VIN13-ATIP1 showed lower levels of expression than that of the control strain.
VIN13-IOE1 behaved as expected, with a decrease of between 30% and 60% in the
total ester level in the wine and base wine respectively, a 30% decrease in the total
acid level and no change in the higher alcohol level. The VIN13-AIAH1 strain showed
no difference to the control wine, most likely as this strain still expressed the IAH1
gene at levels consistent with the control strain. VIN13-TOE1 behaved in an
unexpected manner - instead of hydrolysing esters, it appeared to produce them.
This increase in the total ester level was most noticeable during distillation, when a
20% increase took place. Another unexpected occurrence was a large decline in the
total acid level, with acetic acid being the most significant contributor, decreasing by
up to 78%. This is a very favourable finding, as acetic acid is a known spoilage
molecule and is a cause of sluggish/stuck fermentations. VIN13-ATIP1 behaved in an
opposite manner to VIN13-TOE1, with higher total acid levels and slightly decreased
total ester levels, especially during distillation. Neither affected the total higher
alcohol levels. Sensorially, the only significant difference in the wine samples was for
the fruity flavour. A panel of judges distinguished that VIN13-TOE1 was fruitier than
the other wines, with VIN13-ATIP1 being the least fruity.
This study again proves the significant impact that a single gene can have on the
chemical makeup of wine and brandy. The relatively simple genetic alteration of an
organism can drastically change and improve not only the organoleptic properties of
the organism, but its viability as well. These alterations can produce more favourable
organisms with more desirable characteristics for the fermenting beverage industry to
produce products of higher quality and better suitability. / AFRIKAANSE OPSOMMING: Geen chemiese komponent kan uitgesonderword as die produseerder van aroma en
geur in wyn of brandewyn nie. Die aroma en geur van wyn en brandewyn word
eerder toegeskryf aan die interaksie tussen 'n groot aantal chemiese komponente
om aan die drank sy karakter te gee. Enkele van hierdie chemiese komponente sluit
in esters, terpene en vlugtige sure, om maar 'n paar te noem.
Esters is "n groot groep van vlugtige verbindings wat beskik oor 'n
verskeidenheid van aroma- en geurkenmerke, soos piesangagtig (isoamielasetaat),
appelagtig (etielkaproaat) en chemies/oplosmiddelagtig (etielasetaat). Esters word as
sekondêre metaboliete geproduseer wanneer suikers na etanolomgeskakel word en
word gevorm wanneer "n alkohol met "n vetsuur verbind. Estermetabolisme is
chemies goed beskryf en verstaan, maar op "n genetiese vlak is daar nog heelwat
aspekte wat nagevors moet word. Die gisras betrokke gedurende fermentasie word
beskou as een van die grootse bydraes tot die tipe en die hoeveelheid esters wat
geproduseer word. Dit word toegeskryf aan verskille in die genetiese saamestelling
van die gisras. Ester metabolisme word grootliks deur genetiese faktore beheer en
verskeie gene is betrokke. Dit is hoofsaaklik die alkoholasetieltransferasegene wat vir
esterkatabolisme verantwoordelik is, terwyl die esterasegene vir esteranabolisme
verantwoordelik is. Esterases het 'n negatiewe effek op die totale estervlak binne
alkoholiese dranke deurdat hulle in staat is om die aantal esters drasties te verminder
en sodoende die drank se aroma- en geurprofiel te verander. Daar is voorgestel dat
die IAH1- en die TlP1-geen produkte is wat vir twee sulke esterases kodeer.
Die doel van hierdie studie was om die IAH1- en die TIP1-gene se bydrae tot die
totale estervlak in wyn en brandewyn te ondersoek. Dit is deur twee benaderings
uitgevoer. Eerstens is die bogenoemde gene d.m.V. disrupsiekassette wat homoloog
aan die IAH1- of die TlP1-gene was, uitgeslaan. Die disrupsiekassette is deur die
polimerasekettingreaksie (PKR) geproduseer. Hierdie kassette is in die industriële
wyngis, Saccharomyces cerevisiae VIN13, geïntegreer. Die integrasies is deur
Southernkladanalise bevestig en het die giste VIN13-~IAH1 en VIN13-~TIP1
gelewer. Net 'n enkele kopie van elke geen is egter uitgeslaan. Tweedens is die
IAH1- en TIP1-gene d.m.V. PKR vanaf S. cerevisiae binne in plasmied pJ gekloneer,
tussen die fosfogliseraatkinasegeen (PGK1) se promotor en termineerder, om
plasmiede pJ-IOE1 en pJ-TOE1 te produseer. Die PGK1-promotor is al tevore
geïdentifiseer as "n hoë-vlak konstitutiewe uitdrukker van gene. Hierdie twee nuwe
konstrukte het vervolgens gedien as templaat vir PKR om twee
ooruitdrukkingskassette, een vir IAH1 en die ander vir TIP1, te produseer. Hierdie
kassette is in S. cerevisiae VIN13 geïntegreer en bevestig deur Southernkladanalise.
Hierdie integrasies het die giste VIN13-IOE1 en VIN13-TOE1 geproduseer.
All die nuwe gisrasse, tesame met VIN13, is gebruik vir die produksie van wyne
sowel as rebatwyne vanaf Colombard-mos. Omgekeerde-transkriptase polimerasekettingreaksie (OT-PKR) het bewys dat die VIN13-IOE1 en VIN13-TOE1
rasse die geskikte geen ooruitgedruk het, met hoêr vlakke as van die kontrole
VIN13-ras. Dit het ook aangedui dat die VIN13-i\IAH1-ras, waarvan die geen
uitgeslaan was, geen verskil in uitdrukking gehad het in vergelyking met die
kontroleras nie, terwyl VIN13-i\TIP1 'n lae uitdrukkingsvlak getoon het. VIN13-IOE1
het teen verwagting opgetree, met 'n afname van tussen 30% en 60% in die totale
estervlak in beide die wyne en rebatwyne. 'n Afname van 30% in die totale suurvlak,
asook geen waarneembare verskil in die hoêr alkoholvlak, in vergelyking met die
kontroleras, is ook opgemerk. Die VIN13-i\IAH1-ras het glad nie van die kontroleras
verskil nie, heel waarskynlik omdat hierdie ras die IAH1-geen teen dieselfde vlak as
die kontroleras kon uitdruk. Die VIN13-TOE1-ras het teen verwagting opgetree
deurdat dit esters geproduseer het i.p.v. om esters te hidroliseer. Hierdie toename in
die totale estervlak is die meeste waarneembaar tydens distillasie, met tot 'n 20%
toename. Nog 'n onverwagte effek was die groot afname in die totale suurvlak. met
asynsuur wat die betekenisvolste bydrae gelewer het deurdat dit 'n afname van tot
78% getoon het. Hierdie bevinding is baie voordelig, aangesien asynsuur, 'n bekende
bederfmolekuul, veral vir slepende/gestaakte fermentasies verantwoordelik is.
VIN13-i\TIP1 het op die teenoorgestelde wyse opgetree as VIN13-TOE1, met 'n hoêr
totale suurvlak en 'n klein afname in die totale estervlak. Weereens is dit meer
gedurende distillasie waargeneem. Beide rasse het egter geen effek op die hoêr
alkoholvlak gehad nie. Die proepaneel het, met betrekking tot die vrugtige geur, een
betekenisvolle geurverskil tussen die wyne gevind. VIN13-TOE1 was meer vrugtig as
al die ander wyne en VIN13-i\TIP1 was die minste vrugtig.
Die studie het weereens bewys dat 'n enkele geen 'n betekenisvolle effek op die
chemiese samestelling van wyn en brandewyn kan hê. Die relatief eenvoudige
genetiese verandering van 'n organisme kan die organoleptiese eienskappe asook
die lewensvatbaarheid van "n organisme, drasties verander en verbeter.

Previous issue date: 2018-08-24 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) / En el marco de la educación en salud, tanto la sexualidad como los usos de bebidas alcohólicas son temas que han movilizado discusiones en el ámbito de las políticas públicas y de programas preventivos en Brasil, con base en la búsqueda pela promoción de prácticas que eviten o disminuyan posibles consecuencias perjudiciales como: accidentes; enfermedades; actitudes destructivas y agresivas, en el caso del alcohol; ocurrencias de embarazo no planeado; contracción de VIH y otras infecciones sexualmente transmisibles; estupros y otras formas de violencia sexual, en el caso de la sexualidad. Las experiencias sexuales y las experiencias de consumo de bebidas alcohólicas tienen en común no solo las preocupaciones en relación a los riesgos, sino también como son actualmente valorizadas culturalmente como fuentes de placer. Son experiencias que pueden combinarse, por ejemplo, en expectativas de que las bebidas alcohólicas actúen como facilitadoras de aproximaciones, coqueteo, deseos y placeres sexuales, expectativas relacionadas a cómo las desinhibiciones se vuelven más aceptas y esperadas en las acciones e interacciones entre las personas cuando el consumo de alcohol ocurre. En esta tesis, tuvimos como objetivos investigar las asociaciones entre sexualidad y bebidas alcohólicas, además de identificar posibilidades de diálogo sobre las asociaciones entre ellos. Con el mismo objetivo, desenvolvimos una investigación documental, a partir del análisis del contenido de diez materiales educativos brasileños destinados a la prevención de los usos de bebidas alcohólicas entre adolescentes. A través del análisis, identificamos como son discutidos los temas relacionados a los usos del alcohol, sexualidad, género y placer. Concluimos que para un abordaje más abarcador sobre los temas es necesario que las discusiones educativas envuelvan el diálogo sobre las relaciones, considerando como las experiencias sexuales, las experiencias de consumo de alcohol y las combinaciones entre ellas son atravesadas por expectativas, ansiedades, inseguridades, deseos, temores y placeres que, al convertirse en tema de diálogo con los adolescentes, pueden favorecer una postura reflexiva, sensible y de cuidado frente a las concepciones, actitudes y elecciones en las experiencias y relaciones vividas / No campo da educação em saúde, tanto a sexualidade quanto os usos de bebidas alcoólicas são temas que tem mobilizado discussões no âmbito das políticas públicas e de programas preventivos no Brasil, com base na busca pela promoção de práticas que evitem ou diminuam possíveis consequências prejudiciais como: acidentes; doenças; atitudes destrutivas e agressivas, no caso do álcool; ocorrência de gravidez não planejada; contração de HIV e outras infecções sexualmente transmissíveis; estupros e outras formas de violência sexual, no caso da sexualidade. As experiências sexuais e as experiências de consumo de bebidas alcoólicas têm em comum as preocupações em relação aos riscos, mas também o quanto são atualmente valorizadas culturalmente como fontes de prazeres. São experiências que podem se combinar, por exemplo em expectativas de que as bebidas alcoólicas atuem como facilitadoras de aproximações, paqueras, desejos e prazeres sexuais, expectativas relacionadas a como as desinibições se tornam mais aceitas nas ações e interações entre as pessoas quando o consumo de álcool ocorre. Nesta tese, tivemos como objetivo investigar as associações entre sexualidade e bebidas alcoólicas, assim como identificar possibilidades de diálogo sobre essas associações em abordagens educativas, considerando a importância da inserção da discussão sobre como os prazeres têm sido buscados e experimentados atualmente. Realizamos a revisão de literatura sobre os temas da sexualidade, das bebidas alcoólicas e do prazer, assim como sobre as associações entre eles. Com o mesmo objetivo, desenvolvemos uma pesquisa documental, com a análise de conteúdo de dez materiais educativos brasileiros voltados à prevenção aos usos de bebidas alcoólicas entre adolescentes. Por meio da análise, identificamos como são discutidos os temas relacionados aos usos de álcool, sexualidade, gênero e prazer. Concluímos que para uma abordagem abrangente sobre os temas é necessário que as discussões educativas envolvam o diálogo sobre as relações, considerando como as experiências sexuais, as experiências de consumo de álcool e as combinações entre elas são atravessadas por expectativas, ansiedades, inseguranças, desejos, temores e prazeres que, ao se tornarem tema de diálogo com adolescentes, podem favorecer uma postura reflexiva, sensível e de cuidado diante das concepções, atitudes e escolhas nas experiências e relações vividas. / In the field of health education, sexuality and alcohol use are issues that have mobilized discussions in the scope of public policies and preventive progams in Brazil, based on the search for the promotion of practices that avoid or reduce possible harmful consequences such as: accidents; diseases; destructive and aggressive behaviors, in the case of alcohol; occurrence of unplanned pregnancy; contraction of HIV and other sexual transmitted diseases; rape and other ways of sexual violence, in the case of sexuality; The sexual experiences and the experiences of alcohol consumption have in common the concerns related to the risks, but also the way they are valued culturally nowadays as pleasure resources. They are experiences which can be connected, for example when there are expectations that the alcoholic beverages act as facilitators of approximation, flirting, sexual desires and pleasures, expectations that are related to the fact that disinhibitions become more accepted in actions and interactions that happen among people when there is alcohol consumption. On this thesis, we aimed to investigate the assotiations between sexuality and alcoholic beverages, and also to identify possibilities of dialogue about this associations in educative approaches, considering the importance of the insertion of the discussion about how pleasures have been searched and experienced nowadays. We developed a literature review about the issues of sexuality, alcohol beverages and pleasure, and also about how the issues are associated. With the same aim, we made a documental research, with the contente analysis of ten brazilian educative materials directed to the prevention of alcohol consumption among teenagers. Through the analysis, we identified how the issues related to alcohol, sexuality, gender and pleasure are discussed. We concluded that for a broad approach it is necessary that the educative discussions involve the dialogue about the relationships, considering how the sexual experiences, the drinking experiences and the associations betweem them are traversed by expectations, anxieties, insecurities, desires, fears and pleasures. When these questions become issues of dialogue with teenagers, the reflexive, sensitive and caring position with the conceptions, atitudes and choices can be favored in the lived experiences and relationships

Foram reunidas informações sobre as técnicas qualitativas mais utilizadas para avaliar e compreender a atitude e o comportamento do consumidor de alimentos e bebidas, incluindo a técnica qualiquantitativa denominada Discurso do Sujeito Coletivo. Foi também realizado um estudo cross-cultural para avaliar o hábito de consumo de bebidas não alcoólicas de praticantes de atividade física no Brasil e em Portugal. Indivíduos frequentadores de academias de ginástica voluntariamente responderam a questionário estruturado contendo questões sobre dados sócio-demográficos e hábito de consumo de bebidas não alcoólicas. Esta etapa do trabalho foi realizada com o objetivo de identificar consumidores de bebidas não alcoólicas e recrutar indivíduos para posterior entrevista usando a técnica do DSC. Para avaliar a percepção dos consumidores de bebidas não alcoólicas sobre alimentos funcionais inicialmente foram estabelecidos critérios para aplicar o DSC e realizadas entrevistas individuais semiestruturadas. Para avaliar a expectativa do consumidor de bebida funcional não alcoólica os participantes foram estimulados a expor suas expectativas em relação ao tipo de bebida, à aparência, cor, sabor, textura, benefícios à saúde e informação do rótulo, imaginando que fossem desenvolver um produto e lançá-lo no mercado. O DSC foi avaliado segundo as idéias-centrais (ICs), as expressões-chave (ECHs) e o discurso.

Information about the qualitative techniques most commonly used was pooled to evaluate and understand the attitude and behavior of the consumer of food and beverages, including the qualiquantitative technique the Discourse of the Collective Subject. A cross-cultural study was also performed to evaluate the consumption of non-alcoholic beverages of physical activity practitioners in Brazil and Portugal. Practitioners of physical activity from fitness centers voluntarily responded to a structured questionnaire which addressed socio-demographic data and habit of consumption of non-alcoholic beverages. This stage of the work was performed in order to identify consumers of non-alcoholic beverages and recruit individuals for subsequent interview using the DCS technique. Initially, after establishing the criteria to apply the DCS, semi-structured interviews were performed to evaluate the perception of non-alcoholic beverages consumers of functional food. To evaluate consumer expectation of non-alcoholic functional beverages, the participants were encouraged to express their expectations regarding beverage characteristics such as kind, color, flavor, texture, appearance, health benefits, and labeling information, imagining that they would develop and launch a product on the market. The DCS was evaluated according to the central ideas (CIs), key expressions (KEs) and discourse. Among the qualitative techniques used to assess consumer behavior, the DCS technique stands out by using qualitative and quantitative approach in order to evaluate the need, perception, preference, attitude and decision of consumers.

Expectativa do consumidor de bebida funcional não alcoólica e percepção de alimentos funcionais /Menegario, Alessandra Carvalho Ferrarezi. January 2014 (has links)
Orientador : Magali Monteiro da Silva / Coorientador: Camila Pinelli / Banca: Natália Soares Janzantti / Banca: Renata de Marchi / Banca: Fernando Lefevre / Banca: Jorge Herman Behrens / Resumo: Este trabalho teve como objetivo avaliar e interpretar a expectativa do consumidor de bebida funcional não alcoólica no Brasil e em Portugal usando a técnica do Discurso do Sujeito Coletivo (DSC). Foram reunidas informações sobre as técnicas qualitativas mais utilizadas para avaliar e compreender a atitude e o comportamento do consumidor de alimentos e bebidas, incluindo a técnica qualiquantitativa denominada Discurso do Sujeito Coletivo. Foi também realizado um estudo cross-cultural para avaliar o hábito de consumo de bebidas não alcoólicas de praticantes de atividade física no Brasil e em Portugal. Indivíduos frequentadores de academias de ginástica voluntariamente responderam a questionário estruturado contendo questões sobre dados sócio-demográficos e hábito de consumo de bebidas não alcoólicas. Esta etapa do trabalho foi realizada com o objetivo de identificar consumidores de bebidas não alcoólicas e recrutar indivíduos para posterior entrevista usando a técnica do DSC. Para avaliar a percepção dos consumidores de bebidas não alcoólicas sobre alimentos funcionais inicialmente foram estabelecidos critérios para aplicar o DSC e realizadas entrevistas individuais semiestruturadas. Para avaliar a expectativa do consumidor de bebida funcional não alcoólica os participantes foram estimulados a expor suas expectativas em relação ao tipo de bebida, à aparência, cor, sabor, textura, benefícios à saúde e informação do rótulo, imaginando que fossem desenvolver um produto e lançá-lo no mercado. O DSC foi avaliado segundo as idéias-centrais (ICs), as expressões-chave (ECHs) e o discurso. Dentre as técnicas qualitativas usadas para avaliar o comportamento do consumidor, a técnica do DSC se destaca por utilizar uma abordagem qualiquantitativa, permitindo avaliar a necessidade, percepção, preferência, atitude e decisão dos consumidores. O perfil dos praticantes de atividade física em academias de ... / Abstract: This study evaluates and interprets consumer expectation of non-alcoholic functional beverage in Brazil and Portugal using the Discourse of the Collective Subject (DCS) technique. Information about the qualitative techniques most commonly used was pooled to evaluate and understand the attitude and behavior of the consumer of food and beverages, including the qualiquantitative technique the Discourse of the Collective Subject. A cross-cultural study was also performed to evaluate the consumption of non-alcoholic beverages of physical activity practitioners in Brazil and Portugal. Practitioners of physical activity from fitness centers voluntarily responded to a structured questionnaire which addressed socio-demographic data and habit of consumption of non-alcoholic beverages. This stage of the work was performed in order to identify consumers of non-alcoholic beverages and recruit individuals for subsequent interview using the DCS technique. Initially, after establishing the criteria to apply the DCS, semi-structured interviews were performed to evaluate the perception of non-alcoholic beverages consumers of functional food. To evaluate consumer expectation of non-alcoholic functional beverages, the participants were encouraged to express their expectations regarding beverage characteristics such as kind, color, flavor, texture, appearance, health benefits, and labeling information, imagining that they would develop and launch a product on the market. The DCS was evaluated according to the central ideas (CIs), key expressions (KEs) and discourse. Among the qualitative techniques used to assess consumer behavior, the DCS technique stands out by using qualitative and quantitative approach in order to evaluate the need, perception, preference, attitude and decision of consumers. The profile of physical activity practitioners in fitness centers in Brazil and Portugal was distinct. The majority of participants were 20 to 40 years old, ... / Doutor

A influência da família no consumo de álcool na adolescência / Family influence on alcohol consumption during adolescenceBetânia da Mata Ribeiro Gomes 28 September 2012 (has links)
Embora os fatores de risco ao consumo de drogas sejam bastante conhecidos, ainda pouco se sabe sobre a dinâmica e a organização das famílias de adolescentes que consomem álcool, assim como suas interrelações com a comunidade. Buscando compreendê-las, esta pesquisa objetivou analisar e interpretar a influência da família no consumo de álcool por adolescentes, a partir dos referenciais teóricos do interacionismo simbólico e da perspectiva sistêmica de família. Para tanto, adotou-se como campo de estudo a Unidade de Saúde da Família Emocy Krause, localizada no Distrito Sanitário IV, da cidade do Recife, Pernambuco, Brasil. Os participantes do estudo foram 22 membros de dez famílias, dentre os quais estavam onze adolescentes, de ambos os sexos, na faixa etária de quatorze a dezenove anos, e que consumiam álcool. As técnicas utilizadas para coleta de dados foram: observação e entrevista em profundidade, baseada modelo Calgary de Avaliação da Família, para obtenção de informações que permitissem a avaliação dos componentes estrutural, de desenvolvimento e funcional das famílias, além da construção do genograma e do ecomapa familiar. A análise dos dados foi realizada empregando-se a análise temática do tipo indutiva. Foram elaborados três temas: na internalidade da família: fragilidade e conflitos; entre nós: limites, responsabilidades e esperança; e decisão pela bebida: diversão permeada por riscos. O primeiro tema aborda as fragilidades das famílias, como as relações interpessoais conflituosas, o padrão de comunicação intrafamiliar, a experiência de separação e as perdas, e os conflitos vividos entre seus componentes. O segundo tema trata da interação entre os componentes da família, caracterizada pela desestruturação, envolvendo o consumo abusivo de bebidas alcoólicas pelos familiares e desrespeito, marcando os limites de atuação da família que contribuíram para que os adolescentes se aproximassem das bebidas alcoólicas. Mesmo assim, a família não se eximiu de sua responsabilidade para com seus membros, bem como manteve a esperança, nutrida pelas aspirações e religião dos seus membros. Por fim, a decisão pela bebida retrata o contexto do consumo de álcool e as motivações para esse consumo. Os adolescentes apontaram como motivos o prazer e a diversão, sem ignorar os prejuízos do uso abusivo da bebida alcoólica. A diversão associou-se a músicas que se aproximavam do contexto de vida dos adolescentes, incentivando o consumo de bebidas e funcionando como escape dos problemas familiares. Concluiu-se que, tanto a família quanto o contexto sociocultural de inserção dos adolescentes podem influenciar, ao mesmo tempo, de forma positiva e negativa o uso e o abuso de álcool. A estrutura e composição da família, o padrão de interação familiar, a comunicação entre seus membros, a religião e a esperança são componentes que ser articulam diretamente com a prática do consumo de álcool pelos adolescentes e podem ser alvo de intervenção na enfermagem. / Although the risk factors for drugs consumption are well known, little is known so far about the dynamics and organization of families of adolescents who consume alcohol, as well as about their interrelations with the community. In the attempt to understand them, this research aimed to analyze and interpret the influence of the family on alcohol consumption by adolescents, based on the theoretical frameworks of symbolic interactionism and the systemic family perspective. Therefore, the place of study was the Family Health Unit Emocy Krause, located in Health District IV in Recife, Pernambuco, Brazil. The study subjects were 22 members of ten families, including eleven male and female adolescents between 14 and 19 years old who consumed alcohol and were considered index cases. The following data collection techniques were used: observation and in-depth interview, based on the Calgary Model of Family Assessment, to obtain information to assess the structural, development and functional components of the families, besides the construction of the genogram and the family ecomap. Inductive thematic analysis was used to analyze the data. Three themes were elaborated: in the familys internality: weakness and conflicts; among us: limits, responsibilities and hope and desire for the drink: diversion permeated by risks. The first theme addresses the families weaknesses, including conflicting interpersonal relations, the intra-family communication standard, the separation experience and losses, and conflicts experienced among family members. The second theme refers to the interaction among family members, characterizes by loss of structure, involving alcohol abuse by family members and disrespect, outlining family activities that contributed for adolescents to approach alcoholic beverages. Nevertheless, the family did not refuse the responsibility towards its members and kept up hope, nourished by aspirations and members religion. Finally, the decision to drink pictures the consumption context and the motivations to consume alcohol. The adolescents appointed pleasure and fun as motives, without ignoring the harm of alcohol abuse. Fun was associated with songs that approached the adolescents life context, encouraging drinking and functioning as an escape from family problems. It was concluded that both the family and the adolescents sociocultural context can influence alcohol use and abuse positively and negatively at the same time. The family structure and composition, the family interaction standard, communication among family members, religion and hope are components that directly articulate with adolescents alcohol consumption and can be targets of nursing intervention.

Nelson Mandela Metropolitan University students' perceptions of television advertisements for four SAB beer brandsTye, Robyn January 2013 (has links)
This research study aimed to provide the South African beer industry and their advertising representative with insights into 18-28-year-olds’ perceptions of the communicated messaged in beer advertisements. This included the use of social and cultural references to attract their attention and the suggestions made by the advertisements about the consumption of beer in certain contexts. This research study aimed to determine the selected sample’s (NMMU students) perceptions of four South African Breweries beer brands, namely Castle Lager, Castle Lite, Carling Black Label and Hansa Pilsener, in terms of their use of references to social and cultural identity of males and females in South Africa within their television advertisements. The survey questionnaire helped determine what the selected sample’s perceptions were of each advertisement, and whether they fully understood the desired communicated message. It also helped to understand whether each advertisement captured their attention. A semiotic analysis of each advertisement was conducted to deconstruct the advertisements and to determine if they do contain elements of social and cultural identity in an attempt to sell products to their target audiences, or to affect the perceptions of the brand and drinking beer in general. This was achieved by examining the signs and imagery in each advertisement, looking specifically at the representamen, interpretant and object using Pierce’s model of a sign. / Hierdie navorsingstudie is daarop gemik om die Suid-Afrikaanse bierbedryf en sy adverteerders ‘n beter begrip te gee van verbruikers tussen die ouderdomme van 18-28, se waarnemings van die boodskappe in bieradvertensies. Dit sluit in die gebruik van sosiale en kulturele verwysings, wat veronderstel is om die verbruikers se aandag te trek, asook die suggesties wat deur die advertensies gemaak word met betrekking tot die verbruik van bier in ‘n bepaalde konteks. Die studie moes ook die gekose monster (“selected sample”), nl. die NMMU-student se persepsies bepaal van vier handelsname van die South African Breweries, naamlik Castle Lager, Castle Lite, Carling Black Label en Hansa Pilsener, en in watter mate daar in bieradvertensies oor die televisie verwys word na die sosiale en kulturele identiteit van Suid-Afrikaanse mans en vroue. Die meningspeiling het die groep se waarnemings van elke advertensie, asook of die boodskap wat gekommunikeer is ten volle verstaan word, ondersoek. Die vraelys kon ook vasstel of die advertensies hulle aandag getrek het. ‘n Semiotiese ontleding van elke advertensie is gedoen, om die advertensies te dekodeer en sodoende vas te stel of die adverteerders elemente van sosiale en kulturele identiteit gebruik het om hul produkte aan die teikenmarkte te verkoop, of om die idees rondom die handelsnaam en bier oor die algemeen te beïnvloed. Aan die hand van Peirce se semiotiese model is die tekens en beelde in elke advertensie bestudeer.

Cross cultural study of drinking patterns in three ethnic groups : Coast Salish Indians of the Mission Researve, immigrant Italians and Anglo-Saxons of East VancouverBuckley, Patricia Lorraine January 1968 (has links)
Amongst the important social problems today in both rural
and urban areas, is the condition of inebriety. Although considerable
research has been conducted on the condition of alcoholism, little has
been undertaken on the condition of inebriety. It is an observable
fact that, while members of some ethnic groups who drink substantially
and frequently become inebriated, members of other ethnic groups who
also partake of alcoholic beverages in substantial quantities do not
experience inebriety. This suggests that the culture of the ethnic
group determines the group's drinking patterns to a large measure, and
that drinking patterns may be such that they lead participants to the
condition of inebriety. In this thesis, I have attempted to examine
drinking patterns of three ethnic groups in relation to several aspects
of their cultural background. I devised and tested five hypotheses which
are relevant to attitudes towards drinking, reasons for drinking, settings
and times of the day in which drinking occurs. I have attempted
also to examine Indian and Italian drinking patterns to determine to
what extent each group matches or differs from Anglo-Saxon drinking patterns.
The study was made on a comparative basis, and field work
was conducted amongst three ethnic groups in the Greater Vancouver area
during the summer, fall and winter, 1967-1968. The three groups are
the Coast Salish Indians of the Mission Reserve, Immigrant Italians and
Anglo-Saxons of East Vancouver. Data on the problem briefly outlined above, were sought through interviews with thirty representatives of
each group, as well as by observations of members of the ethnic groups
in their social drinking establishments. Two key informants in each
ethnic group, as well as several pertinent documentary sources, were
also consulted.
The available data collected in the study suggested that the
proposed hypotheses were valid. There appears to be a close relationship
between the cultural background of an ethnic group and its drinking
patterns. However, it needs to be stated that there were many
inadequacies and limitations in the reference literature used, basic
premises and hypotheses proposed, and research techniques employed.
Data also suggested that there was a high degree of similarity between
Anglo-Saxon and Indian drinking patterns and a high degree of difference
between Anglo-Saxon and Italian drinking patterns. Additional and
enlightening information which the data suggested was that many of the
cultural aspects of the Indian group, particularly, are in a marked
stage of transition. / Arts, Faculty of / Anthropology, Department of / Graduate
