Investigating Physical Activity Type, Frequency of Physical Activity, Motives on Physical Activity, and Social Physique Anxiety Among Undergraduate Females

Robitaille, Fawnia 29 April 2014 (has links)
Physical activity has multiple health benefits, however, physical activity can also lead to the development of excessive exercise, disturbed eating patterns, negative body image and social physique anxiety. This study investigated the relationship between social physique anxiety (SPA), physical activity type, frequency of physical activity, and motives to exercise. Participants were female undergraduates (N=108) enrolled at the University of Victoria. Female students were recruited from Exercise, Physical and Health Education classes that were open to all students from different faculties. A cross-sectional survey assessed social physique anxiety, frequency of physical activity and motives for exercise as well as dividing students according to physical activity type (Varsity, Intramural, High Strenuous Exerciser, Low Strenuous Exerciser). An analysis of variance revealed no association between SPA and physical activity type. Additionally, correlations showed that SPA and frequency of physical activity was not significant. Interestingly, SPA was significant for all motives that include Interest (r=-.371, p<.01), Competence (r=-.330, p<.01), Appearance (r=.430), Fitness (r=-.215, p<.05), and Social (r=-.406, p<.01). A linear regression revealed that only Appearance and Social motives predicted SPA. / Graduate / 0573 / 0347 / 0566 / fawniar@uvic.ca

Utilizou-se 21 ovelhas da raça Santa Inês, com idade média de seis anos, que foram distribuídas nos respectivos tratamentos: OL = ovelhas que permaneceram por 60 dias em lactação com seus respectivos cordeiros e abatidas um dia após o desmame dos mesmos; OSC = ovelhas que permaneceram por 60 dias em lactação com seus respectivos cordeiros e mais um período aproximado de 30 dias sem os cordeiros, no intuito de recuperar o peso corporal perdido durante o período de amamentação e posteriormente abatidas; e ONP = ovelhas que permaneceram por 60 dias em confinamento e que não pariram durante o ano. Os resultados obtidos nesta pesquisa evidenciaram que as ovelhas do ONP apresentaram maiores rendimentos de carcaça quente (45,00%) e fria (44,73%) em comparação às fêmeas do OL (40,80% e 40,66%). O rendimento verdadeiro foi próximo entre as fêmeas dos diferentes tratamentos, com valor médio de 50,10%. Os rendimentos dos cortes da carcaça (paleta, pescoço, costelas, lombo e perna) foram similares entre todas as ovelhas abatidas nas distintas condições fisiológicas, com valores médios de 18,78%, 9,34%, 27,36%, 7,77%, e 34,70%, respectivamente. Os rendimentos dos não componentes da carcaça foram similares entre as ovelhas abatidas em diferentes estágios fisiológicos, com exceção dos valores do fígado, do sangue, do úbere e da gordura interna. O resultado econômico foi positivo para todos os tratamentos experimentais, no entanto o melhor retorno financeiro foi obtido para os animais do tratamento OSC e o pior para os do tratamento ONP. / The experiment was carried out aiming to evaluate discard ewes slaughtered in different physiological stages and terminated in confinement, as for carcass yields and its cuts, as well as the percentages of each non-component of the carcass and the economical result of the preparation of these animals for slaughtering. 21 Santa Inês ewes were used, with average age of six years old, distributed into the following treatments: EL = ewes which remained in lactation for 60 days with their respective lambs and slaughtered one day after weaning of the lambs; EWL = ewes that remained in lactation for 60 days with their respective lambs and other 30 days approximately without lambs, aiming to recover lost body weight during breastfeeding, and, subsequently, slaughtered; and ENC = ewes that remained in confinement for 60 days and did not deliver during the year. The results obtained in this research showed that ewes from ENC presented higher hot (45.00%) and cold (44.73%) carcass yields, compared to females from EL (40.80% and 40.66%). True yield was proximate between females from the different treatments, with average value of 50.10%. Carcass cuts (shoulderblade, neck, ribs, loin and leg) yields were similar among all ewes slaughtered in the distinct physiological conditions, with average values of 18.78%, 9.34%, 27.36%, 7.77% and 34,70%, respectively. Carcass non-components yields were similar among ewes slaughtered in different physiological stages, except for liver, blood, udder values and internal fat. The economical result was positive for all experimental treatments; however, the best financial return was obtained for animals from treatment EWL and the worst for animals from treatment ENC.

Efeito da concentração do sêmen e horário de inseminação artificial a tempo fixo sobre a prenhez em fêmeas bovinas de corte. / Effect of semen concentration and moment of fixed timed insemination on pregnancy results in beef cattle females

Rocha, Dimas C. January 2007 (has links)
Em experimento conduzido com o objetivo de avaliar os efeitos da concentração da dose de sêmen e o horário da inseminação artificial a tempo pré-fixado, foram utilizadas 516 fêmeas bovinas. Os animais, das raças Aberdeen Angus (Bos taurus) e Braford (Bos taurus 5/8 x Bos indicus 3/8) eram constituídos de 270 novilhas e 246 vacas multíparas. Os animais foram submetidos a um protocolo de sincronização de estros e ovulação através de implante vaginal contendo 250 mg de Acetato de Medroxiprogesterona (MAP) associado a duas aplicações de Benzoato de Estradiol (BE), sendo a primeira de 2 mg IM por ocasião da inserção do implante e a segunda de 1 mg IM vinte e quatro horas após a retirada do mesmo. Quando da remoção do implante foram administrados 500 mcg de Cloprostenol Sódico. As inseminações foram efetuadas às 48, 54 ou 60 horas após a retirada do implante, utilizando para cada momento duas concentrações distintas de espermatozóides viáveis, 10 e 20 milhões por dose. Verificou-se que as fêmeas (em especial as novilhas) inseminadas às 48 horas com 20 milhões de sptz/dose apresentaram índice de prenhez significativamente maior do que as inseminadas no mesmo momento com 10 milhões sptz/dose. As vacas inseminadas com 10 milhões de sptz às 60h apresentaram melhor taxa de prenhez (p<0,05) quando comparadas às inseminadas com 10 milhões de sptz às 48h. O percentual de prenhez encontrado nas vacas foi significativamente maior que o das novilhas, assim como o verificado nas fêmeas Aberdeen Angus, comparadas às Braford. A taxa de prenhez de novilhas inseminadas a tempo fixo pode ser incrementada utilizando-se maior número de espermatozóides viáveis por dose inseminante. / The objective of this study was to analyse the effects of semen concentration and moment of fixed timed insemination on pregnancy rates in 516 beef cattle females of the Aberdeen Angus (Bos taurus) and Braford (Bos taurus 5/8 x Bos indicus 3/8) breeds. The females were constituted of 270 heifers and 246 multiparous cows. The animals were all submitted to a synchronization program consisting of vaginal implants of 250mg of medroxiprogesterone acetate (MPA) associated to application of 2mg IM of estradiol benzoate (EB).After 7 days the implants were removed and 500 mg of cloprostenol were injected at the time. After 24hs of implant removal 1mg IM of EB was injected. The inseminations were done 48, 54 and 60 hours after the removal of the implants and semen with 10 and 20 million viable spermatozoa per dosis was used. The females (specially the heifers) of the group inseminated 48 hours after implant removal and using semen with 20 million viable sptz showed a significant higher percentage of pregnancy than the inseminated 48 hours using 10 million viable sptz. The cows inseminated at 60 hours with 10 million sptz showed higher pregnancy rates (p<0,05) than cows inseminated at 48 hours with 10 million sptz. The total pregnancy rate achieved on the cows was significantly higher than on the heifers. The females of the A. Angus group had higher pregnancy rates than the females of the Braford breed. The pregnancy rate of heifers fixed-timed inseminated can be increased using a higher semen concentration.

The representation of female politicians in Zimbabwean print media : 2000-2008

Parichi, Mandiedza 11 1900 (has links)
This study is motivated by the realisation that, in post-2000 Zimbabwe, while the contest pitting one political formation against another has been given prominence in the media, an important struggle that has attracted little attention during this period has been that of the genders, in particular the competition between men and women for the right and power to govern the country. Media organisations have participated in this struggle by developing and distributing images of the various interest groups in the political fray, including men and women. The media has, thus, played a key role in developing conceptual tools to apprehend the condition of female and male politicians in Zimbabwean society (Bhebhe, 2016), thereby implicitly distributing power to one or the other group. This study has, therefore, examined the representation of female politicians in three Zimbabwean newspapers, namely Kwayedza, The Standard and the Financial Gazette, during the four election held between 2000 and 2008. The study was guided by the following concerns: the way images of female politicians were projected in the print media in Zimbabwe during the period in question, how the political affiliation of the three newspapers influenced the coverage of female politicians, and how female politicians were represented in different languages (i.e.Shona and English). The study tested the following hypotheses: women were generally represented as unfit for public office; images developed by the different newspapers were determined by the newspapers’ preference between the two major political parties, the Zimbabwe African National Union Patriotic Front (ZANU PF) and the Movement for Democratic Change (MDC); the representation of female politicians was determined by the language (Shona or English) used by the newspaper; and newspaper owners determined the way female politicians were portrayed. The study made use of qualitative content analysis to examine the representation of female politicians in the above-named newspapers, coding selected stories in terms of these frames: female politicians as mothers and housewives, and female politicians as inadequate and unfit for political office, as well as double bind dilemmas. As expected, the privately-ownednewspapers, the Financial Gazette and The Standard, negatively portrayed ZANU PF female politicians negatively, while the state-owned Kwayedza was hostile to MDC female politicians. The study, however found that, beyond this inevitable trait of a polarised media, all three newspapers shared many tendencies in their coverage of female politicians. For instance, across the three newspapers, female politicians were marginalized through iv omission. They were also trivialised by being portrayed in terms of frames irrelevant to politics. Thus, of the three newspapers, only The Standard did not make use of the motherhood and wifehood frame in its representation of female politicians. More significantly, the double bind dilemma is a rhetoric device that permeates stories on female politicians in all three newspapers to the extent that, even in those stories where the two frames were used, the frames are constructed in terms of double binds. Zimbabwean female politicians are thus portrayed as hamstrung candidates, neither fit for public office nor eligible for marriage and motherhood. This double bind is particularly damaging for indigenous black Zimbabwean female politicians since a major finding of this study is that the stories examined construct motherhood as a powerful form of elevation of female politicians as it is consistently associated with a select few female politicians, the elite of Zimbabwean politics, those at very apex of the political pyramid. This makes the combination of the frames and the double bind dilemma much more harmful to the careers of Zimbabwean female politicians than it would be in a non-African context. / Communication Science / D.

Att ta plats är att ge plats : Hur kvinnor som moshar förstår och förhandlar kropp, kön och rum ur ett feministiskt fenomenologiskt perspektiv

Denward, Hilda January 2018 (has links)
The aim of this paper is to examine how women who mosh to hardcore music understand moshing as a meaning making activity and how they understand and negotiate body, gender and space in their relation to moshing. I have done a feminist phenomenological analysis on four deep interviews with women who mosh based on the theories of Sara Ahmed and Iris Young. I have found that my informants discuss moshing in terms of feelings of adrenaline, euphoria, strength and emotional ventilation. They break the norms of female bodily performance at the same time as they feel uncomfortable with how their bodies stand out in relation to the white and male bodies as a norm in hardcore spaces. The women then use how their own and other bodies that stand out as a way to access space and as a ground for resistance, both against the room as masculine and as white. The women show a clear feministic orientation and use a violent bodily performance as a feminist practice.

Análise e descrição de estruturas temporárias presentes no período ovígero de isópodos terrestres (Crustacea, Oniscidea)

Appel, Carina de Souza January 2011 (has links)
A presença do marsúpio fechado possibilitou aos isópodos terrestres a total independência do meio aquático para a reprodução, permitindo aos mesmos a colonização de habitats terrestres variados. Em seu interior, a prole é nutrida e oxigenada através de estruturas temporárias, chamadas cotilédones, as quais surgem durante o período ovígero das fêmeas e são exclusivas do grupo Crinocheta. O presente estudo teve como objetivo descrever padrões dos cotilédones, analisados em 37 espécies de isópodos terrestres distribuídas entre as famílias: Agnaridae, Armadillidae, Armadillidiidae, Balloniscidae, Bathytropidae, Detonidae, Dubioniscidae, Philosciidae, Platyarthridae, Porcellionidae, Pudeoniscidae, Scleropactidae e Trachelipodidae, verificando se ocorre variação de comprimento ao longo das fases de desenvolvimento embrionário, sendo que para isto foram selecionadas seis espécies: Armadillidium nasatum, A. vulgare, Atlantoscia floridana, Balloniscus sellowii, Benthana cairensis e Porcellio scaber. Armadillidium vulgare e B. sellowii também foram estimados quanto à proporção comprimento dos cotilédones/ tamanho da fêmea. Entre as 13 famílias estudadas foram identificados seis formatos (tipos) de cotilédones e sete arranjos diferentes de número e distribuição. O comprimento foi estabelecido como: curto, médio e longo. Armadillidium vulgare, A. floridana e B. cairensis não apresentaram diferença no comprimento dos cotilédones durante os estágios embrionários sendo que este foi evidenciado para as demais espécies, uma vez que B. sellowii e P. scaber apresentaram aumento da fase de ovo para embrião, diminuindo na fase de manca. Já em A. nasatum ocorre um aumento gradual até a fase de manca, onde então regridem drasticamente. O comprimento dos cotilédones de A. vulgare e B. sellowii é proporcional ao tamanho da fêmea. Durante os estudos realizados outra novidade foi registrada: a presença de uma “extensão marsupial”. Para maiores informações sobre esta estrutura, foi necessário identificar quais espécies a apresentavam, o número de indivíduos abrigados em seu interior e diferenças na estrutura entre as espécies que portavam tal extensão e as que possuem o marsúpio fechado restrito aos cinco pares de oostegitos. Seis espécies apresentaram extensão marsupial, a qual possibilita o abrigo de aproximadamente ¼ do total da prole. XI Este marsúpio não apresenta formato distendido como o encontrado nas demais espécies o que vem a influenciar diretamente a alimentação da fêmea, pois com o desenvolvimento da prole ocorrendo em direção aos órgãos desta, conforme avançam as fases, aumenta a pressão interna, comprimindo seu interior. As diferenças morfológicas registradas aqui representam estratégias reprodutivas adotadas pelas espécies, ao longo da evolução, podendo estar relacionadas (ou não) à filogenia dos grupos. / The presence of the closed brood pouch made it possible for terrestrial isopods to have full independence of the aquatic environment for reproduction, allowing them to colonize varied terrestrial habitats. Inside, the offspring is nourished and oxygenated by temporary structures, called cotyledons, which emerge during the ovigerous period of females and are unique to the group Crinocheta. This study aims to describe patterns of cotyledons, analyzed in 37 species of terrestrial isopods distributed among the families: Agnaridae, Armadillidae, Armadillidiidae, Balloniscidae, Bathytropidae, Detonidae, Dubioniscidae, "Philoscidae" Platyarthridae, Porcellionidae, Pudeoniscidae, Scleropactidae and Trachelipodidae , checking if there is variation in length along the stages of embryonic development, and for this, six species were selected as models: Armadillidium nasatum, A. vulgare, Atlantoscia floridana Balloniscus sellowii, Porcellio scaber and Benthana cairensis. Armadillidium vulgare and B. sellowii were also estimated concerning the proportion of cotyledon length / female size. Among the 13 studied families six formats (types) of cotyledons were identified as well as seven different arrangements of numbers and distribution. The length was established as: short, medium and long. Armadillidium vulgare, A. floridana and B. cairensis showed no difference in the length of the cotyledons during the embryonic stages while this was evidenced for the other species, since B. sellowii and P. scaber showed increased egg stage to the embryo, decreasing during the manca. Nevertheless in A. nasatum a gradual increase until the phase of manca occurs, which then regresses dramatically. The length of the cotyledons of A. vulgare and B. sellowii is proportional to female size. XIII During the carried out studies another new feature was recorded: the presence of an " marsupial extension." For obtaining further information about this structure it was necessary to identify the species that presented it, the number of individuals housed within, and differences in structure between species that harbored such extension and the others which had the closed pouch restricted to five pairs of oostegits. Six species showed marsupial extension, which provides shelter for approximately a quarter of the total offspring. This brood pouch does not have a distended format as the one found in other species, which directly influences the feeding of the female, because due to the fact that the offspring development occurs towards its organs as the stages advance, internal pressure increases, compressing its interior. The morphological differences reported here represent reproductive strategies adopted by the species, through evolution and could be related (or not) to the phylogeny of the groups.
