Kustnära ekosystem som skydd mot naturkatastrofer : en litteraturstudie från ett riskhanteringsperspektiv

Research suggests that society's vulnerability to natural disasters along coasts could increase as a result of climate change, which is likely to lead to elevated sea levels and possibly an increase in the occurance of meteorological phenomena such as storms and tropical cyclones. Following the Indian Ocean tsunami disaster in 2004 and Hurricane Katrina in 2005, both of which received considerable media attention, empirical data has indicated that coastal vegetation might be able to protect and reduce damages to coastal communities during tsunami events and tropical cyclones.The aim of the essay has been to study the function of coastal ecosystems as protection against tsunami waves and storms from a risk management perspective, meaning that I have, through an overview of scientific articles, compiled current research on how coastal ecosystems can attenuate storm surges and tsunami waves, and analysed how this knowledge can be put into practice in coastal communities from a risk management perspective, i.e. if coastal ecosystems are a viable risk reduction measure, are practically applicable, and if so, how they could be applied.There is empirical evidence suggesting that coastal ecosystems, particularly mangroves, can reduce the strength of a tsunami wave, but full scientific consensus on this issue has not yet been reached. With regard to protection against storm surges, there is extensive scientific evidence that coastal vegetation can mitigate damages and reduce the height of a storm surge, although the wave has to traverse several kilometres inland through thick vegetation for the protection to be effective. A synthesis in the form of a figure regarding the many physical factors that influence wave development through coastal ecosystems has been created in an attempt to simplify and explain the phenomenon.The conservation and restoration of coastal ecosystems can be justified from a risk management perspective, but planting new forest belts for the purpose of disaster mitigation is quite unrealistic and can rarely be sustainable, since, for protection to be effective, the forest belt must extend several kilometres inland from the coast, and would thus likely prove difficult to implement along coastal societies..

Vasastaden och gentrifieringsprocessen 1970-2010

Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.

Vad driver svenska swapspreadar? En regressionsmodell med ECT

Uppsatsen är en kvantitativ studie som undersöker vilka faktorer som har kunnat förklara den svenska swapspreaden under tidsperioden 2001-12-31 till 2008-10-31. Resultatet är en linjär regressions modell som påvisar att swapspreaden är kointegrerad med svenska statens upplåningsbehov samt räntespreaden för europeiska kommersiella obligationer. På kort sikt förklaras swapspreaden av bland annat att den är mean reverting kring ett långsiktigt samband med tidigare nämnda variablerna, basis risken, den historiska volatiliteten på aktiemarknaden, bankaktiers utveckling i förhållande till övriga aktiemarknaden samt lutningen på Money Market kurvan..

Kulturprojektets karaktär : Perspektiv på ett lyckat resultat

Projects is the most common work model within the cultural area, but what is a cultural project? The definition of cultural projects is ambiguous. There are also no compiled information about what it means for culture to be pursued in project form. Scientific research about traditional project management and success criterias are wide-ranging. So is the scientific research about cultural studies and cultural policy.

Skola på vetenskaplig grund : hur uppfattar lärare och skolledare att de kan realisera skollagens skrivning om vetenskaplig grund i skola och förskola

Den här uppsatsen undersöker ett antal attityder till skollagens skrivning att utbildningen skall vila på vetenskaplig grund med syftet att få en bättre förståelse för vilka förutsättningar och uppfattningar och vilket utgångsläge som finns för lagens implementering. Emperin har hämtats från en totalundersökning med en kvantitativ enkät som har skickats ut till skolledare och lärare i skola och förskola i en mindre kommun. Svarsfrekvensen för undersökningen är 40 %. Datan har sedan analyserats och visas som deskriptiv statistik. Uppsatsen har en fenomenologisk utgångspunkt.

Praxis och praktik i flerspråkiga tesaurer

A prerequisite of an international exchange of information is multilingual tools for information retrieval, such as the multilingual thesaurus. There is an ongoing discussion about the construction of, and the guidelines for, multilingual thesauri. In recent years the praxis as defined in ISO 5964 Guidelines for the establishment and development of multilingual thesauri 1985 has been the topic of a scientific discussion. It has been about how equivalence across languages is to be established when it comes to concepts, terms and relational structures. This masters thesis treats the praxis and practice of multilingual thesaurus construction.

Patienters upplevelse av omvårdnad efter suicidförsök : En litteraturöversikt

INTRODUCTION: Attempted suicide is very common. Those who arrive to a hospital by reason of attempted suicide need a nurse with qualifications in the care of suicidal patients. OBJECTIVE: The aim of this study was to compile and elucidate research which describes how patients in care for their attempted suicide experience the care that is received. METHOD: A literature review was chosen for this study. Scientific articles sought in the database CINAHL.

"Det är roligt!" : En studie om hur pedagoger använder estetiska lärprocesser i arbetet med naturvetenskap i förskolan

The purpose of this thesis is to investigate how teachers perceive that they work with science in preschool through aesthetic learning processes as tools both in the indoor and outdoor environment and make visible what the educators' underlying beliefs are that affect how they perceive aesthetic learning processes as tools used to deepen children's understanding of different scientific phenomena.This is an interview study using the phenomenographic approach as a means and method to make visible and report on teachers' views on how aesthetic learning processes can be used to extend preschool children's learning about science. The results are analyzed and discussed based on John Dewey's theoretical ideas about children's learning, aesthetics and science.The study clearly shows that teachers' views on aesthetic learning processes and how they can be used in the work whit science is very divided and in some cases unreflective. The most striking results are that teachers often are unaware that they make use of aesthetic learning processes because they have a more limited view of what it is than we have in the paper. All informants have science as a core subject. Their focus of the activity is located at the showing and visualizeing of scientific phenomena and some of them express that they submit the aesthetic learning processes to their colleagues or that they collaborate with someone who has training in some art form.

Avlastningsarmstöd till Grip-it : Optimal positionering av övre extremitet vid gripstyrkemätningar

In today?s technological society, there are increasingly less physical demands on the locomotor system. However, despite that notion strength and function in the hand?s complex biomechanical system are in fact both needed to cope with daily life. The grip function is a main function in the hand and is used in many examples of scientific research, for instance when assessing physical health and predicting the probabilities of premature mortality.

Värmeväxlare med luftkonditionering för tvättstugor

The energy in laundry rooms, in form heated air, can be utilized with a heat exchanger. A concept and an early prototype of the heat exchanger have already been developed to show that the theory works. This report describes the continued development and construction of the product.A field study was made in order to investigate the environmental usage and establish the product design. The most common washing machine was used as a calculation model, and calculations were also made to estimate the amount of energy in the air. A previous analysis of the existing prototype is also presented in this report, to show the products potential capacity.

Virtuella Communities: Sociala faktorer i digitala miljöer

Virtual Communities is an increasingly common phenomenon on the Internet. Most of the Virtual Communities are operated and maintained on a non-profit basis with a direction towards entertainment. However, as more state administrated and commercial services become web-based, we believe that the number of Virtual Communities with a community-based or commercial direction will increase in a near future. In this thesis, we describe our participation in, and studies of, a number of Virtual Communities with focus on the IRC-channel ?3dfxsweden?. On the basis of our experiences, we describe the social elements that form the foundation on which the Virtual Community rely on.

Kommunikation mellan bank och kund: en studie angående kommunikationen mellan akademiker med några års arbetslivserfarenhet och banken

The purpose of this thesis was to examine what the communication between bank and customer looks like. We have more specifically studied how the bank communicates with the customer when communicating different offers, how the customer wants the communication to take place, what communication problem looks like and how the customer wants the bank to design their offers. Our target group was bank customers with academic degree, with one to seven years of working experience. This study was conducted trough interviews with bank customers and representatives at the bank. On the basis of our studies we found that the communication between bank and customer works fairly well.

Bakomliggande faktorer till presbyacusis; en litteraturstudie av mindre kända faktorer

Background: More than half of the elderly (65-84 years) in Sweden have problems with hearing. In some studiesit?s discussed if age related hearing loss or presbyacusis is a part of natural aging or if it depends on underlyingfactors.The purpose of this literature study was to analyse scientific papers which illustrate correlations between lessknown underlying factors and presbyacusis, defined from psychoacoustic and/or neurofysiological tests.Material and method; Literature study where scientific papers, relevant to the purpose of the study and thequestions at issue were found in the database PubMed.The result shows that cardiovascular disease, hormones, diet and drugs have an influence on presbyacusis. Thehealth condition of the individual and their lifestyle matters, likewise estrogen which according to the results of 2studies has a protective effect on hearing.Conclusion; The studies show that heart attack and high systolic blood pressure in women have a correlation topresbyacusis, but not in men, - the hormone estrogen, - some vitamins, antioxidants and diet have a protectiveeffect on hearing and studies show that smoking and alcohol have negative effects..

En övervikt av kvinnor : En kvantitativ studie av bilder och skribenter på Aftonbladets viktsajt ur ett genusperspektiv

We have investigated the visual representation of men and women in Aftonbladet?s weight site. We have made a calculation of how many of the women and the men who were portrayed smiling/ not smiling, active/passive, looking into the camera/looking away from the camera and from which camera angle the picture is taken. We also kept statistic on the gender representation of the authors of the articles.Our investigation shows that Aftonbladet?s weight site has a distinct overrepresentation of women on their pictures, but also in terms of the authors of the articles.
