Rising temperatures, because of climate change, will have major consequences for the world's fish populations, including the Atlantic salmon Salmo salar L. The greatest temperature changes are expected to occur during winter, which will affect S. salar since the eggs are developing during this time of year. Several studies have shown that elevated temperatures during embryogenesis cause morphological changes, in S. Salar, that are shown in later life stages. Some of these studies indicate that eggs incubated at high temperatures should generate parr with deeper bodies. To investigate whether high temperatures during the egg stage cause changes in body shape, parr from normal and high temperature incubated eggs, referred to as as “cold” and “warm” fish, respectively, were examined. A box-truss of euclidean distances between 10 landmarks on the fish body and a discriminant function analysis (DFA) was used to determine which of the distances best discriminated between the two groups. The test showed a significant discrimination between cold and warm parr regarding body shape where cold parr had greater heads and warm parr were deeper over the tail region and showed greater distances between the pelvic fin and the front attachment of the anal fin. 67,3 % of all parr where correctly classified by the test. These results support those notions that indicates that the incubation temperature is important for the morphological development of S. salar although it does not support the hypothesis. / Stigande temperaturer, till följd av klimatförändringar kommer att få stora konsekvenser för jordens fiskpopulationer, däribland atlantlaxen Salmo. Salar L. Störst temperaturförändringar väntas ske vintertid, vilket kommer att påverka S. Salar som övervintrar sin rom. Flera studier har visat att förhöjda temperaturer under embryogenesen ger upphov till morfologiska förändringar hos S. Salar under senare livsstadier. Några studier pekar mot att högtemperaturinkuberad rom torde ge upphov till parr med djupare kroppsform. För att undersöka om höga temperaturer under romstadiet ger upphov till förändringar beträffande kroppsform undersöktes parr (kalla resp. varma) från normal-  respektive högtemperaturinkuberad rom. Med hjälp av ett rutnät / box-truss mättes avstånd mellan 10 landmärken på fiskkroppen och en discriminant function analysis DFA användes för att avgöra vilket av avstånden som bäst diskriminerade mellan de båda grupperna. Testet visade en signifikant diskriminering mellan kalla och varma parr beträffande kroppsform där kalla parr hade större huvudmått och varma parr hade djupare mått över stjärtspolen och längre mått mellan analfenans främre infästning och bukfenan.  67,3 % av all parr förutspåddes tillhöra rätt grupp. Dessa resultat är i linje med den litteratur som anger att inkuberingstemperaturen har betydelse för den morfologiska utvecklingen hos S. Salar däremot stödjer de inte den angivna hypotesen.

Ridbyxor är ett specifikt plagg för ryttare och det ställs därför vissa krav som inte uppkommer på vanliga byxor. Bakgrunden till detta arbete är att företaget bad om ett mönster till en ridbyxa med bra passform genom hela storleksserien. Ett nytt mönster med god grundpassform tas därför fram. Graderingen av byxan gjordes med tanke på hur plagget ska användas samt hur kroppen förändrar sig i de olika storlekarna. Idag tas oftast ingen hänsyn till detta utan plaggen behåller samma proportioner i alla storlekar. För att uppnå ett slutresultat har konstruktionen gjorts i Lectras konfektionsanpassade cad-program Modaris och specifikationerna har gjorts i Illustrator och PISA. En god grundpassform togs fram först genom ett antal avprovningar och mönsterförändringar innan graderingsarbetet tog vid. För att verifiera graderingen gjordes avprovningar på utvalda storlekar. Slutligen kommer grundstorleken att sys upp i fabrik och två ytterligare storlekar att sys upp i Textilhögskolans lokaler. Resultatet visar att relativt många förändringar måste utföras på grundkonstruktionen för att uppnå den passform som önskas. Samt att en gradering som ger en längre grenlängd bak skapar en bättre passform när ryttaren sitter i sadeln. / Breeches are a specific garment for equestrians and therefore it occur certain requirements which are not imposed in regular trousers. The background to this writing is that the company asked for a pair of breeches with good fit throughout the size range. A new pattern with good fit is therefore produced. The grading of the trousers was made in view of how the garment will be used and how the body changes in the various sizes. Today there is often no attention dedicated to this. The result is that the garment retains the same proportions in all sizes. To achieve a result has the patterns been made in Lectras software Modaris and the specifications are made in Illustrator and PISA. A good fit in base size is first achieved thru a number of fittings and pattern changes before the grading work started. To verify the grading fittings of selected sizes was performed. Finally will the base size be sewn at a factory and further two sizes will be sewn at Textilhögskolan. The result shows that relatively many changes must be performed on the basic pattern to achieve the desired fit. And that a grading that gives a longer back rise length is creating a better fit for equestrians when sitting in the saddle.

Androgen receptor (AR) gene CAG polymorphisms may be associated with body shape, and are associated with certain breast and prostate cancers. In addition, body shape is associated with risk for a variety of diseases, including heart disease, diabetes, and certain forms of cancer. The CAG repeat in exon l of the AR gene was quantified using Perkin Elmer Applied Biosystems GeneScan analysis software in 96 and 59 healthy Caucasian men and women, respectively, who were over the age of 50 years. All participants had body measurements taken and donated a blood sample. Waist measurements included circumferences at the 1) umbilicus (wstumb), 2) top of the iliac crest (wstili), and 3) midpoint between the lowest rib and the iliac crest (wstwst). Waist-hip ratio (Wl-IR) was calculated using each corresponding waist measurement, respectively (WHRUMB, WHRILI, WHRWST). Mean repeat length was significantly different (p < 0.01) between men (22 ± 0.3 repeats) and women (23 ± 0.3 repeats). There was a significant relationship (p < 0.05) between mean individual CAG repeat number and tertile of WHRUMB in women based on the mean number of CAG repeats for each woman. Waist measurements in women were significantly different for all pairwise comparisons (p < 0.05). In addition, the three measurements of WHR in women, WHRUMB, WHRILI, and WHRWST, were significantly different from each other (p < 0.05). Thus, lesser numbers of CAG repeats may indicate a more androgenic phenotype in women.

This study investigates the impact of sociocultural mediators in relation to eating disorders among male undergraduates. Literature on eating disorders has demonstrated that a thin body shape ideal depicted in the media directly contributes to eating pathology among females, but little research has investigated the direct effects of ideal body shape images among men. The focus of the present investigation was to assess the direct effects of exposure to the ideal male body shape on men’s affect, self esteem, body satisfaction, and endorsement of U. S. societal ideals of attractiveness. In addition, the relation of these variables to bulimic symptomatology was examined. Modeling a study conducted on women (Stice & Shaw, 1994), male undergraduates between the ages of 18 to 25 participated in premeasure (N = 169) and post measure (N = 95) conditions. Participants in the post measure were randomly exposed to pictures from magazines containing either male models depicting the ideal body shape, an average body or pictures of clothing without models. Results from repeated mulitvariate analysis indicated that exposure to the ideal body shape condition did not demonstrate significant negative changes in men’s affect, self esteem, body satisfaction or endorsement of U. S. societal ideals of attractiveness. Indirect support for the sociocultural theory of eating disorders was provided by multiple regression analyses which demonstrated that increased body mass, self esteem, stress and anxiety predicted bulimic symptomatology in men. Future research should direct itself toward investigating possible sociocultural influences of eating disorders on certain male subenvironments, such as athletes or homosexual males that place a greater emphasis on maintaining lower body mass and an ideal body shape.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Crustaceans of the genus Aegla occur in continental waters, in southern South America. The genus is composed by more than 70 species, most of them characterized by having restricted distributions. Unlike this pattern, the species Aegla longirostri and Aegla platensis have wide geographic distributions. Moreover, both species form non-monophyletic groups, which may indicate that these groups are formed by cryptic species. Therefore, the objective of this study was to analyze populations of A. longirostri and A. platensis through a geometric morphometric approach, in order to clarify their intraspecific relationships. For A. longirostri, we analyzed 120 individuals from 6 populations, totalizing 20 animals per population. For A. platensis, we analyzed 110 individuals from 11 populations (four Argentinean and seven Brazilian), totalizing 10 animals per population. For both species, the animals were photographed in dorsal view, and 19 landmarks were defined on the carapace. Both sides of the carapace were symmetrized, and the landmarks coordinates were superimposed. Variations in centroid size were tested with an analysis of variance (ANOVA) and Tukey s test. For A. longirostri, we also used a Procrustes ANOVA. Variations in carapace shape were explored through a principal component analysis (PCA), and afterwards through a linear discriminant analysis (LDA) and a canonical variate analysis (CVA), based on the first 8 principal components. The Mahalanobis distances between the populations were calculated. For statistical test of carapace shape differences, we used multivariate analysis of variance (MANOVA), and for pairwise comparisons among populations we used Bonferroni corrections for adjust of p-value after multiple MANOVAs. For A. longirostri, CV1 and CV2 represented 46.5% and 23.1% of the variation, respectively. The most geographically distant population showed the highest values of Mahalanobis distance. The pairwise comparisons showed that all populations of A. longirostri differ significantly in carapace shape. For A. platensis, CV1 and CV2 represented 28.5% and 22.2% of the variation, respectively. There was a separation between Argentinean and Brazilian populations, with high values of Mahalanobis distances between populations from both countries. The pairwise comparisons showed that all populations of A. platensis differ significantly in carapace shape, with the exception of a pair of Argentinean populations and a pair of Brazilian populations. Some characteristics of the aeglids indicate that these animals may have low dispersal potential, thus the geographic distance may have led to an interruption of the gene flow between populations. Added to the non-monophyletic grouping, the intraspecific difference in carapace shape in A. longirostri and A. platensis could be an evidence that populations of both species are fragmented. / Crustáceos do gênero Aegla ocorrem em águas continentais, no sul da América do Sul. O gênero é composto por mais de 70 espécies, caracterizadas em sua maioria por possuírem distribuições restritas. Ao contrário deste padrão, as espécies Aegla longirostri e Aegla platensis possuem distribuições geográficas amplas. Além disso, ambas as espécies formam agrupamentos não-monofiléticos, o que pode indicar que esses agrupamentos são formados por espécies crípticas. Portanto, o objetivo deste estudo foi analisar populações de A. longirostri e A. platensis através de técnicas de morfometria geométrica, visando esclarecer suas relações intraespecíficas. Para A. longirostri, foram analisados 120 indivíduos provenientes de seis populações, totalizando 20 animais de cada população. Para A. platensis, foram analisados 110 indivíduos provenientes de 11 populações (quatro argentinas e sete brasileiras), totalizando 10 animais de cada população. Para ambas as espécies, os animais foram fotografados em vista dorsal e foram selecionados 19 marcos anatômicos localizados na carapaça. Ambos os lados da carapaça foram simetrizados e as coordenadas dos marcos anatômicos foram sobrepostas. Variações no tamanho do centroide foram testadas através de análise de variância (ANOVA) de um critério e teste de Tukey. Para A. longirostri, também foi utilizada ANOVA de Procrustes. Variações na forma da carapaça foram exploradas através de análise de componentes principais (PCA), e posteriormente através de análise linear discriminante (LDA) e análise de variáveis canônicas (CVA), com base nos 8 primeiros componentes principais. Foi calculada a distância de Mahalanobis entre as populações. Variações na forma da carapaça foram testadas através de análise de variância multivariada (MANOVA) e MANOVAs par a par seguidas por correção de Bonferroni. Para A. longirostri, CV1 e CV2 corresponderam a 46,5% e 23,1% da variação, respectivamente. A população mais distante geograficamente apresentou os maiores valores de distância de Mahalanobis. As MANOVAs par a par demonstraram que todas as populações de A. longirostri diferem significativamente na forma da carapaça. Para A. platensis, CV1 e CV2 corresponderam a 28,5% e 22,2% da variação, respectivamente. Houve uma separação entre as populações argentinas e brasileiras, com valores de distância de Mahalanobis maiores entre as populações dos dois países. As MANOVAs par a par demonstraram que todas as populações de A. platensis diferem significativamente na forma da carapaça, com exceção de um par de populações argentinas e um par de populações brasileiras. Algumas características dos eglídeos indicam que esses animais possuem baixo potencial de dispersão, portanto, a distância geográfica pode ter levado à interrupção do fluxo gênico entre as populações. Somada à ausência de monofilia, a diferença intraespecífica na forma da carapaça em A. longirostri e A. platensis pode ser um indício de que populações de ambas as espécies estão fragmentadas.

Obesity has become a global pandemic that not only affects adults, but also children and adolescents. It has been found that obesity among children and adolescents has emotional, social, physical and psychological ramifications, one of which is bullying. Very little has been written on the effects obesity in early adolescence has on bullying behaviour in a South African context. For this reason the researcher deemed it necessary to study the perceptions of youths in early adolescence with regard to obesity and bullying. Semi-structured interviews were conducted with 35 early adolescents from the Brooklyn policing precinct in the east of Pretoria. The data were assessed through content and interpretative phenomenological analysis. Thus the researcher tried to capture the essence of each individual interview. Several themes emerged from the data analysis, of which the most noteworthy were what youths in early adolescence perceive as bullying; the influence of bullying on behaviour; a general overview of perpetrators and victims of bullying; and the correlation between an early adolescent’s body shape and victimisation. The findings give insight into how obese young adolescents are perceived and treated by their peers. Furthermore, the findings elucidate what early adolescents perceive as bullying and possible reasons for such behaviour. By identifying the perceptions held by early adolescents, programmes can be implemented to address these stereotypes, thus decreasing the potential victimisation of overweight/obese youths in early adolescence. / Dissertation (MA)--University of Pretoria, 2013. / Social Work and Criminology / unrestricted

Kraven inom textilindustrin förändras genom åren, förutom senaste modetrenden, funktionella material är plaggets passform en viktig aspekt för kundnöjdhet. Studien skrivs i samarbete med ett modeföretag med inriktning mot fast fashion. Syftet är att undersöka passformsproblem på överdelsplagg för dam med djup halshål både fram och bak. Balans- problem och fel vinkling av halsringningen är ett återkommande passformsproblem på dessa modeller som leverantörerna inte lyckas få till. Problemet är störst på deras ärmlösa afton -klänningar där denna variant av modell tillverkas mest. I denna studie ligger fokuset på att undersöka passformen på aftonklänningar utan ärm för att kunna hitta alternativa passformslösningar som kan vara till hjälp för företaget. Studiens har genomförts i två steg. En förstudie av företagets gamla modeller utfördes i första hand för att kunna identifiera passformsproblemet. Detta har verifieras genom avprovningar på provpersoner med olika kroppstyper/ kroppshållning, för att kunna få en övergripande bild över passformen. Nästa steg sker genom digitalt mönsterkonstruktion för att kunna skapa en förbättrad modell med djup halsringning både fram och bak. Studiens resultat visar att många olika faktorer påverkar passformen. Bland annat placering av insnittet, axelns lutning samt hur halshålet vinklas vid konstruktion har en stor avgörande del för modellens passform. / The demands in the textile industry are changing over the years, besides from the latest fashion trend, functional materials, garment's fit is an important aspect for customer satisfaction. The study is written in collaboration with a fashion company focusing on fast fashion. The purpose of study is to analyze fitting issue on upper body garments for ladies wear with deep neck line front and back. Balance problem and wrong angling of neckline is a recurring fit problem on these models that the suppliers fail to achieve. Most of the fitting problem is on their sleeveless evening dresses where this type of model is manufactured most. In this study, the focus is on examining the fit of evening dresses without sleeves in order to be able to find fitting solutions that can be helpful to the company. The study approach has been done in two steps. A preliminary study of the company's old models was analyzed to be able to identify fit problem. This has been verified by testing on human body with different body types / posture, in order to get an overall view of the fit. The next step has been through cad based pattern design to be able to create an improved model with deep neckline both front and back. The study's results show that many different factors affect the fit. For instance, placement of the incision, the shoulder slope and how the neckline angles in pattern making is crucial for the fit of the model.

Världen blir alltmer digital och att handla kläder via internet är idag en självklarhet för många. Undersökningen syftar till att utforska hur företag kommunicerar passform till konsument, oavsett om de bedriver online försäljning eller enbart använder sina hemsidor för att exponera sitt sortiment. Denna studie kommer undersöka vilka verktyg som är vanligt förekommande, hur de kan kombineras och vad de förmedlar till konsument. En litteraturöversikt ligger till grund för studien och i nästa steg har en kvantitativ urvalsundersökning tagit plats där 45st företag som tillhandahåller överdelsplagg för dam/herr undersökts. I sista steget har en teoretisk kartläggning där verktygen jämförts mot faktorer som påverkar passform har utförts för att klargöra vad varje verktyg kommunicerar. Forskningen som studien bygger på förtydligar problematiken kring passformskommunikation då detta kan anses vara ett subjektivt ämne där fysiska och mentala värderingar påverkar hur konsumenten upplever passform. Resultatet visar att de flesta företag använder sig av kroppsmåttlista i kombination med bildillustrationer för att förtydliga plaggets passform. Den teoretiska kartläggningens resultat visar att visuella och virtuella verktyg ger konsumenten en bättre indikation på plaggets passform. / The world is becoming increasingly digital and shopping for clothes via the internet is a matter of course for many today. The survey aims to explore how companies communicate fit to the consumer, whether they conduct online sales or only use their websites to expose their range. This study will examine which tools are commonly used, how they can be combined and what they convey to the consumer. A literature review is the basis for the study and in the next step, a quantitative sample survey has taken place where 45 companies that provide tops for women / men have been examined. In the last step, a theoretical survey where the tools have been compared against factors that affect fit has been performed to clarify what each tool communicates. The research on which the study is based clarifies the problem of fit communication as this can be considered a subjective subject where physical and mental values affect how the consumer experiences fit. The results show that most companies use body measurements in combination with image illustrations to clarify the garment's fit. The results of the theoretical survey show that visual and virtual tools give the consumer a better indication of the garment's fit.
