Amfibier i nyanlagda våtmarker : En fältstudie i Laholms jordbrukslandskap

Many species of amphibians are threatened both in Sweden and globally. The causes are many and a main factor is habitat alterations which often results in populations being isolated. Changes in the agricultural landscape have among other things resulted in small water bodies being filled and dried out and that has severely affected the Swedish amphibians. Swedish amphibians are depended upon small water bodies for their Reproduction. Wetlands have been constructed to reduce the impacts of the eutrophication in the Laholm bay.

Feromoninnehållande substansers effekt på hjärtfrekvensen hos kvigor i östrus och diöstrus :

With increased milkproduction in our dairy cattle, comes a risk for a reduced fertility. Studies performed on animals and humans have shown that it is possible to manipulate the oestrous cycle through exposure to pheromones. This means that pheromones could potentionally be used to make Reproduction more efficient. To evaluate the bioactivity of the substances in question, there is need for a bioassay. In insects, pheromones can induce a changed cardiac activity.

Effekt på östralcykeln hos ston tillförda GnRH-analogen deslorelin (Ovuplant) :

This article starts with a review of the literature regarding the normal reproductive physiology of the mare, prolonged luteal phase and medical drugs used within Reproduction of the horse, with emphasis on Ovuplant®. The purpose of this article was to measure the progesterone level in blood, of mares implanted with deslorelin acetate (Ovuplant®). The study was performed at the Department of Clinical Sciences, SLU, in Uppsala. There were seven mares included in the study. They were divided into two groups, one experimental group (four mares) and one control group (three mares).

CORRELATION BETWEEN ENDOMETRIAL MARKERS AND PREGNANCYOUTCOME IN WOMEN WITH UNEXPLAINED INFERTILITY

ABSTRACTA defect implantation process is the major reason for unexplained infertility. Estrogen andprogesterone are steroid hormones preparing the endometrium for implantation. They mediatetheir effect through their receptors: estrogen receptor alpha and beta and progesteronereceptor A and B, respectively. Leukemia inhibitory factor (LIF), which is also important forimplantation, mediates its effect through LIF receptor and the coreceptor, gp130, and is downregulated by suppressors of cytokine signaling 1. The aim of the study was to compare thelevels of the steroid hormone receptors and LIF related factors in the endometrium of twogroups of women with the diagnosis unexplained infertility: one that became pregnant afterassisted Reproduction and one that did not become pregnant.

Ansvarsfulla män och omoraliska kvinnor : En narrativ analys av det politiska mediedrevet rörande Borg, Billström, Borelius och Stegö Chilò

In October 2006 the media began investigating the four ministers Billström, Borg, Borelius and Stegö Chilò who were all being accused of miner tax fraud. The two women, Stegö Chilò and Borelius became the primary victims of an extensive media hunt where the media already had made their minds up; the women had to go. The more the women tried to explain themselves, they only seemed to be digging themselves into a deeper hole and ten days into the ?hunt?, the media got their way, the women resigned while the men, even today remain on their positions. What was it then that made the outcome so different regarding the four ministers when the only thing to really set them apart was their genders?With support of theories from Giddens, Habermas and Thompson as well as theories regarding media, gender and the medias ethical responsibility we have in a qualitatively narrative analysis studied 20 articles from Dagens Nyheter and Expressen.

Kriminella, offer, resurs, börda: Diskurser om ?papperslösa? i svenska dagstidningar

This qualitative study is focused on the way ?papperslösa? (undocumented/illegal/irregular immigrants) are portrayed in Swedish daily newspapers, what images are presented in the articles, what discourses permeate the text, what identities are being constructed, etc. The empirical data consists of thirteen articles published in Dagens Nyheter and Svenska Dagbladet (two of the biggest daily news papers in Sweden) during the period 2010-10-01 ? 2011-04-01, and I?ve used a type of discourse analysis called ?diskursanalys med inriktning på identitetskonstruktion? (?discourse analysis with focus on identity construction?), as the method to analyze the articles. The results of the analysis showed that four discourses and identities were constructed, re-produced and upheld in these articles.

Ur ett genusperspektiv : En kvalitativ innehållsanalys av två utbildningsprogram: Home Farm Twins och Rena rama forntiden

Our aim with this study is to investigate whether or not Utbildningsradions - which is a public broadcasting agency - educational programmes reproduce the existing gender patterns of the female and male genders. We have chosen to analyse two educational programmes, Home Farm Twins and Rena rama forntiden.We use a social constructionist theory regarding the construction and Reproduction of gender and the method we have chosen to use is a qualitative content analysis to study the educational programmes.Our conclusion is that in the case of Home Farm Twins, it reproduces the current stereotypes that exist in society. Rena rama forntiden on the other hand does not, the program has got a clear gender perspective in regards to its content. Though it can be said that in some ways it does not reflect upon the gender patterns that exist in society today, to a satisfactionary extent.Utbildningsradion does not achieve its policy concerning Home Farm Twins, but on the other hand it shows that in the case of Rena rama forntiden they do own up to the standards regarding cultural diversity and creative aim..

De vuxna maskrosbarnen : en kvalitativ intervjustudie

Syftet med denna kvalitativa intervjustudie var att med hjälp av sociologiska teorier undersöka orsakerna till att maskrosbarn trots en destruktiv uppväxtmiljö kan utvecklas till socialt fungerande människor. Maskrosbarnen i denna studie har vuxit upp med missbruk och/eller psykisk sjukdom hos föräldrar i barndomen. Data samlades in via semistrukturerade intervjuer med fyra olika teman: det sociala arvet, skola och arbete, socialt nätverk samt hälsa och välmående. Vilket vi sedan analyserade med hjälp av de teoretiska tolkningsramarna, Antonovskys teori KASAM och Bourdieus teori om Klassreproduktion. Resultaten visade att förekomsten av trygghetspersoner i barndomen samt möjligheten att uppleva en annan familjedynamik och miljö än deras egen hemmiljö har påverkat dem positivt.

Berättelser om Sverige. En narrativ analys av nationellt identitetsskapande på Dagens Nyheters insändarsidor

AbstractIn this essay I discuss narrative in the reconstruction of national identity. I discuss exclusion as a side effect in thick identities. That means that thick national identities always exclude another part. From this I´ve discussed the Swedish identity and its effects in the European co-operation. Identity is a discourse that reconstructs linguistically.

Vitrification in sealed containers : Evaluation of a new technique (Rapid-i?) for cleavage stage embryos and blastocysts

Ovarian stimulation in assisted Reproduction often leads to the production of a high number of oocytes. After fertilization of these oocytes, the resulting embryos can be cryopreserved for later use. Vitrification is a recently introduced method for cryostoring embryos, showing high survival rates for both cleavage stage embryos and blastocysts. Characteristic of vitrification are high concentrations of cryoprotectants and ultra fast freezing which makes the material glassily. A major concern with vitrification has been the direct contact of the cryo-solutions with liquid nitrogen.

Rekryteringsprocessen- ett hinder för jämställdhet? : En fallstudie av ett företag där kvinnor är underrepresenterade

Ur ett internationellt perspektiv anses Sverige vara ett jämställt land. Trots detta finnsen utpräglad könssegregering på arbetsmarknaden som ett resultat av traditionellaföreställningar om vad som är kvinnliga och manliga yrken. Träindustrin harhistoriskt sett varit en mansdominerad bransch och det är fortfarande svårt för kvinnoratt få anställning inom den branschen. Vid rekrytering av personal finns möjligheterför företag att förändra den demografiska strukturen hos arbetsstyrkan.Med denna bakgrund ämnade denna studie att undersöka rekryteringsprocessen ur ettjämställdhetsperspektiv på ett utvalt företag inom träindustrin. Företaget har delat insina anställda under två yrkeskategorier, tjänstemän och kollektivpersonal.Underrepresentationen av kvinnor är mest märkbar bland kollektivpersonal och därförstuderades skillnader i hur rekryteringsprocessen ser ut mellan yrkeskategorierna.Studiens resultat visade att jämställdhetsperspektivet inte beaktas i samtliga momentav rekryteringsprocessen.

Utbildningskapital, ekonomiskt kapital och utbildningsstrategi : En deskriptiv utbildningssociologisk studie om gymnasieleverna som antagits till det naturvetenskapliga programmet i Botkyrka kommun

Secondary schools have for decades debated whether they promote social Reproduction which is considered to generate the homogeneous student compositions. The gap between the academic programs and vocational education programs is considered to increase. What in recent years has appeared in research is that the gap is increasing most tend to be in the specific academic program, particularly in science. This paper's intention is to describe the science program at a local level and the pupils who were admitted to the science program autumn 2009 on the basis of an educational sociological perspective. The survey consisted of a census in which all students were given the opportunity to answer a questionnaire.

Meritpoäng : Ungdomars livschanser ur skolchefers perspektiv

This C-essay is a qualitative study designed to create a basis for understanding how managers involved in school affairs perceive the impact of merit points on students? chances to continue on to higher education and how this will affect individuals' life chances.The study is based on three interviews with managers involved in school affairs. In this paper grades, merit points and socioeconomic class differences are discussed.The aim of this paper is to answer the following questions:? What impact does merit points in language studies and the way different languages are valued, in the system, have for the individual and for society?? Who are the winners in the new grading system and who are the losers; how are different socioeconomic groups affected?The material was interpreted with the help of a report written by Ingrid Nordqvist and Monica Langerth Zetterman called "Secondary School competition field-a regional perspective", a paper written by Helen Raven who did a study on grades, national tests and social Reproduction and the Frenchman Pierre Bourdieu's theories.The results show that class differences will increase and that it will be difficult to rise in the social hierarchy in the future..

Svenskdidaktik i (o)jämlikhetens landskap : en studie om språkutveckling, rasifiering och klass

Symbolic resources transform in to social power and material resources through the educational system. This entails that all students should have equal access to it.The essay compares Swedish didactics in ?immigrant? and ?white? schools, all situated in socio-economically underprivileged areas, analysing interviews with eight Swedish teachers about their didactics regarding restricted and elaborated language code.Understanding teacher?s work in the class room requires attention to the intersections between race and class, and of both to the distribution of symbolic resources in general.The essay finds that the practice of the? immigrant? school teachers differs from the ?white? school teachers?. The former are active, providing intellectual tools, scaffolding and driving force while the later choose a more passive attitude, letting students decide for themselves what to do and what goals to reach. Consequently ?white? schools allow the Reproduction of unequal distribution of symbolic resources while practice in immigrant schools aim to compensate for disadvantages.Practice seems to win legitimacy by different sets of conceptualisations.

Interspecies embryo transfer in South American camelids : a field study

The aim of this study was to investigate the possibility of performing inter-species embryo transfer under actual field conditions in the natural habitat of South American camelids. In this study embryos from llamas were transferred to alpaca recipients. In a parallel study alpaca embryos were transferred to llama recipients. All animals used were free of uterine and ovarian abnormalities detectable by rectal palpation and /or ultrasound examination. Embryos were harvested twice after single ovulation in 10 mated female llamas and non-surgically transferred to synchronized alpaca recipients.
