Multicopy gene family evolution on primate Y chromosomes

Ghenu, Ana-Hermina 11 1900 (has links)
Unlike the autosomes, the Y chromosome in humans and other primates has few protein coding genes, with only a few dozen single-copy genes and several tandem duplicated gene families, called the "ampliconic" genes. The interaction of many biological and evolutionary factors is responsible for this structural heterogeneity among different parts of the genome. We sequenced and assayed the copy numbers of Y-linked, single-copy genes and ampliconic genes in a group of closely related macaque monkeys, then fit models of gene family evolution to this data along with whole genome data from human, chimpanzee, and rhesus macaque. Our results (i) recovered evidence for several novel examples of gene conversion in papionin monkeys, (ii) indicate that ampliconic gene families evolve faster than autosomal gene families and than single-copy genes on the Y chromosome, and that (iii) Y-linked singleton and autosomal gene families evolved faster in great apes than they do in other Old World higher Primates. These findings highlight the evolutionary eccentricity of duplicated genes on the Y chromosome and suggest an important role for natural selection and gene conversion in the evolution of Y-linked gene duplicates. / Thesis / Master of Science (MSc)

Nyhetsartiklars inramning av en idrottsorganisation : En studie med fokus på organisationens sociala ansvar / News articles framing of a sports organization

Scherer, Kenny, Gustavsson, Filip, Lundgren, Daniel January 2023 (has links)
Studiens huvudämne är att undersöka hur stora idrottsevenemang presenteras och diskuteras offentligt i samband med företagens sociala ansvar. Syftet med studien är att ta reda på vilka gestaltningar som främst förekommer i nyhetsartiklarna och i vilket sammanhang. Studien försöker också utforska vilka aktörer som förekommer i nyhetsartiklarna och hur det står sig i förhållande till innehållet och värderingarna i artiklarna, men även se hur nyhetsmedier värderar olika aspekter av företagens sociala ansvar i sin bevakning av stora sportevenemang. En kvantitativ innehållsanalys har använts som metod för att analysera 179 artiklar från 4 olika nyhetsmedier för att kunna svara på syftet med studien. Vi kodade artiklarna utifrån ett kodningsschema som bestod av 14 olika variabler. Teoretiska ramar och tidigare forskning som har varit relevanta för denna studie har fokuserats på hur nyhetsmedia framställer stora idrottsevenemang och idrottsorganisationer. Gestaltningsteorin var en av de mest framträdande teorierna vilket vi har använt som teori i denna forskningsstudie. Resultatet visade att sporten är huvudämnet kring det stora idrottsevenemanget. Organisationen själv väljer att fokusera på sporten och organisationen värderades mer positivt än negativt eftersom organisationen är mer kopplad till sporten. Som sekundär aktör värderades organisationen dock mer negativt än positivt eftersom organisationen kopplades då mer till mänskliga rättigheter. Innehållet i artiklarna som kopplades till CSR-områden tenderade att vara mer negativt än positivt. Nyhetsmedierna lyfter fram ansvar och mänskliga intressen i artiklar och när artiklarna handlar om mänskliga rättigheter berör innehållet frågor om moral och konflikter. Förarna är de som tar mest plats i artiklarna och är de aktörer som lyfter fram CSR-områden som mänskliga rättigheter och bidrar mest till diskussionen. / The main subject of this research study is to investigate how major sporting events are portrayed and argued publicly in connection with corporate social responsibility. The aim of the study is to find which frames mainly appear in the news articles and in which context. The study also tries to explore which actors appear in the news articles and how it stands in relation to the content and values in the articles, but also now news media value different aspects of corporate social responsibility in their coverage of major sporting events. A quantitative content analysis has been used as a method to analyze 179 articles from 4 different news media to be able to answer the purpose of the study. We coded the articles based on a coding scheme that consisted of 14 different variables. The theoretical frameworks and previous research that have been relevant to this study has been focused on how the news media portrays major sporting events or sport organizations. Framing theory was one of the most prominent theories and we have used this theory in this research study. The result showed that the sport is the main topic around the major sporting event. The organization itself chooses to focus on the sport and the organization was valued more positively than negatively since the organization is more connected with the sport. As a secondary actor, however, the organization was valued more negatively than positively because the organization is more connected to human rights. The content in the articles that were linked to CSR areas tended to be more negative than positive. The news media highlight responsibility and human interests in articles, and when the articles deal with human rights, the content touches on questions of morality and conflicts. Drivers are the ones who take up the most space in the articles and are the actors who highlight CSR areas such as human rights and contribute the most to the discussion.
