The efficiency of the newly launched predatory mite Amblydromalus limonicus : biological control of thrips in cucumber
In this study, the efficiency of a newly launched predatory mite, Amblydromalus limonicus, has been
examined for its potential to use as a biological control agent in cucumber production. A. limonicus
can be used for biological control of two thrips species, Frankliniella occidentalis and Thrips tabaci.
Field trials were conducted in greenhouses of two conventional cucumber growers in Scania, the
southern part of Sweden. The basic control agent used against thrips was the predatory mite
Amblyseius swirskii. In selected areas, additional A.
Osynliggörandet av äldre HBT-personer : Upplevelser och föreställningar om äldreomsorg
Although Sweden is considered to be in the lead concerning an open-minded perception of the lesbian, gay, bisexual, and transgender (LGBT) population, very little attention has been given to the elderly within this target group. The elder LGBT population?s got special needs that haven?t been made sufficiently visible, neither as a research field, from social institutions nor from the LGBT movement itself. This study has described the target group's specific needs, based on the results of a focus group consisting of older LGBT people. Their experiences and stories have given an idea of what adjustments must be made to satisfy their specific needs.
Målgruppsanpassad verksamhet på folkbiblioteket
My purpose with the study is to investigate if it is possible to argue in favor of organizing public libraries according to the client based theory. To create a base to argue from I have studied UFO, a department focused on young adults at the age between 15 and 25 at the public library of Malmö. This case study, performed by investigating the documentation of UFO as well as conducting an interview with the project leader, is the base from which I then can argue for or against the idea of organizing public libraries according to the client based theory. Public libraries should always reflect the communities they serve. This challenges the staff of different libraries in different regions to arrange their organizations accordingly to their local population and to be flexible enough to follow the changes of this population.
Förutsättningar för skred i Huddinge kommun idag och i ett framtida klimat
It is imperative to provide more information regarding changed conditions resulting landslide events in a future climate. The aim of this thesis is to assess landslide susceptibility in Huddinge Municipality in middle Sweden. The main purpose is to produce a map, to visualize landslide susceptible areas, and to integrate the result with changes in physical factors such as climate change. Also, the thesis aims to analyze anthropogenic factors such as changes in land use and an increasing population in Huddinge Municipality. Methods used are GIS-analyses, interviews with staff of Huddinge Municipality, and field observations.
Latitudinal patterns in body size of Roesel?s bush cricketMetrioptera roeselii within and outside the continuous area of its distribution
Over time, species colonize new areas naturally or through humans. The colonizers areoften few and founded populations represent only a fraction of the genetic diversityexisting in the original population. If the established population becomes isolated afterthe colonization event genetic diversity will remain low and if the population, in addition,remains small in size for an extended period this will lead to increased inbreeding andpossibly inbreeding depression. Metrioptera roeselii is a common species with awidespread distribution in continental Europe. During the last century, it has expanded tothe Scandinavian Peninsula which is separated from continental Europe by the Baltic Sea.My aim was to test the hypothesis that individuals in isolated populations in Scandinaviaincluding Denmark and the Baltic Sea islands are smaller than individuals in thecontinuous part of its distribution due to low genetic diversity and lacking incoming geneflow.
Stanna. Flytta. Återvända? : en studie av unga vuxnas reflektioner om Tärnabyområdets samhällsmiljö.
A great importance for the future of municipalize is the ability to attract and retain the younger part of the population. For the Tärnaby area (a famous tourist resort for alpine skiing), a part of the Storuman municipality, this is a problem, and with a possible mining establishment job opportunities will be provided. In this study I have examined how young adults related to the Tärnaby area have reasoning about stay or move from the area and what may get them to move back.What is the area´s place identity and is it attractive for the respondents? Can a mining establishment change the negative population trend? The results showed that the respondent have a strong connection to the area and the identity of the place. A large proportion of the respondents indicated that they wanted to move back to the area of Tärnaby, if it was possible, due to work-related causes and social relations at existing place of residence. The respondents approach for a potential mining establishment is both of positive and negative sense. However, a mining establishment is considered by the respondents to be of great importance for the future of the Tärnaby area..
Radioktivt cesium (Cs-137) i vildsvin (Sus scrofa) från Tjernobyldrabbade områden i Sverige
In April 1986 an accident occurred at the nuclear power station in Chernobyl. Radionuclides were spread all over Europe including Sweden. Today there are still measurable
concentrations of 137Cs in the different ecosystems in the contaminated parts of Sweden. The wild boar is the second most popular game in Sweden and today the Swedish population
consumes more wild boar meat than ever. As the wild boar population increases the wild boars are moving further north towards the contaminated areas, which creates an interest to study the state of 137Cs in wild boars in these areas.
Muscle samples from wild boars collected during 2010-2013 were analyzed based on 137Cs content.
Människan i naturen : om etiska gränsdragningar och djupekologins kritik av antropocentriska naturuppfattningar
The subject-matter of the following essay is to investigate the relationship between what is commonly called Deep Ecology or Biocentric Philosophy, as articulated by the co-founder of the Deep Ecology Movement, Arne Naess, and later proponents of the biocentric school of environmentalist thought. I contrast Naess? concept of Self-realization as founded in his Ecosophy T to the ideas of american conservationist and co-founder of the radical green movement Earth First! Dave Foreman, and to the controversial finnish environmentalist and ecofascist Pentti Linkola?s ideological agenda of population-reduction respectively.According to some critics of the movement, especially the social ecologist Murray Bookchin and French liberal philosopher Luc Ferry, the Deep Ecology ideology is essentially misanthropic and totalitarian in structure. A central idea among deep ecologists is that ecosystems and natural entities have intrinsic value in themselves, even outside a human social context. This idea is thought of among deep ecologists to create a philosophically sound basis for counteracting the environmental global crisis.
Tracheas dimension hos Engelsk Bulldog : en retrospektiv radiologisk pilotstudie på svenska hundar
There is desire to evaluate the tracheal diameter in the Swedish population of English Bulldog, a breed with breathing disorders, and if possible use it as a criteria for breeding in the hope of improving the life situation for these dogs. The Swedish Kennel Club has together with the Swedish Club for English Bulldog and veterinarians presented a five year radiological study that has the purpose to give an average look on how the tracheal situation is in the population. The trachea will be evaluated through two different methods, both measuring two distances in the thorax. The first one compares the tracheal diameter to the height of the cranial opening of the thorax, and the second one to the width of the third rib. With the measured distances one will calculate a quotient and compares it to the reference values.This study is designed to get a preliminary evaluation, based on the 65 dogs that were available on the time for the study, with measurements done by two persons on three different occasions each.
Att förstå omorganisationer : En studie av det svenska krisberedskapsområdet 2000-2010
Essay in Political Science, C-level, by Camila Alvarez Cea, spring semester 2010. Tutor: Alf Sundin?Reality or a Political Mirage? ? A Study of the Swedish Press Views on the Health Insurance Reform in the USA? The purpose of this essay is partly to examine whether the picture that Swedish press presents of the health insurance reform in the US, which is part of the Patient Protection and Affordable Act bill, will be of crucial importance to the possibilities that the American population has to receive health insurance. The main research question is accordingly: ?Does the picture that Swedish press presents of the health insurance reform in the USA, seem like something that will be of radical importance to the possibilities of the population to receive healthcare?? The purpose is also to examine in which model (demand or market) the opinions of the Swedish press fits. This purpose will be answered by using three specific questions asking whether their opinions differ when it comes to three criterions: organization, financing/resources and delivery systems.
Undersökning av förekomst av okända virus hos svenska fjällrävar med encefalit :
The artic fox is under threat of extermination in Europe. The population decreased strongly at the beginning of the twentieth century because of intensive hunting. The artic fox was placed under protection by law 1928 in Sweden but despite this the population has had difficultly to recover. This can depend on several reasons, but the main threats are shortage of food and competition from the red fox. Along with Norway and Finland, Sweden has carried out a project called SEFALO (Saving the Endangered Fennoscandian Alopex lagopus), whose objectives were to prevent continued decreased populationnumbers and through, for example supplementary feeding, help the population to recover.
Känslomässig instabilitet och dess påverkan på arbetssökande beteende i en svensk population
Sambandet mellan personlighet och arbetssökande beteende har mestadels undersökts bland studenter tidigare. Denna studie undersökte om känslomässig instabilitet påverkade sättet att söka arbete hos 123 arbetssökande icke-studenter mellan 20-65 år. Enkäten som användes bestod av Personality Questionnaire (Bäccman & Carlstedt, 2010), som mäter personligheten utifrån femfaktorsmodellen, samt Job Search Behavior (Blau, 1994), som mäter förberedande och aktiva arbetssökande beteenden. Det fanns ett samband mellan känslomässig instabilitet och båda arbetssökande beteenden. Känslomässig instabilitet kunde dock inte ensam predicera vilket arbetssökande beteende individer väljer, men tillsammans med ålder kunde känslomässig instabilitet predicera förberedande arbetssökande, och ålder kunde även ensamt predicera förberedande arbetssökande.
Medierepresentationen av världens länder : Strukturer i fyra svenska nyhetstidningar
This essay casts light on the quantitative aspect of the media representation of foreign news. The purpose of the essay is not only to describe the media representation of the countries of the world, but also to explain the representation out of structures that are mirrored by the mass media. Four hypotheses are stated that are operationalized in the research. These are treating four different factors that are believed to affect the representation, economy, geographical distance, cultural distance and the size of the population. A fifth hypothesis is stating that economy is the most influential of the factors.
Bibliotekariens kunskap: En textanalys av SOU 1969:37
The aim with this Masters thesis is to examine the professional knowledge of the librarian. The method used is text analysis of a state public investigation, SOU 1969:37, that concerns librarian education. The theoretical starting point is a theory of knowledge thats descended from Aristotle. Three different forms of knowledge are central concepts in the theory: the theoretical, the practical and the ethical. The main issue in this thesis is: In what ways did the investigators look at the librarians knowledge? Was it in a changeable period of time? In that case, what reasons could there be? The conclusion shows that educational political changes were affecting the whole educational sphere at the late 1960:s, and in the beginning of the 1970:s, including library education.
