Sex differences in feeding visit rates in Northern Wheatears Oenanthe oenanthe

AbstractThe Northern Wheatear (Oenanthe oenanthe) is a small insectivorous passerine bird living in open landscapes. Both parents feed the brood of approximately five chicks, but little is known about how each sex allocates their feeding effort. In this study I investigate feeding nest visit differences between male and female Northern Wheatears relative to the age of the chicks, the number of chicks and the quality of the territory for 17 pairs from 2008-2010. Data were collected using automated data loggers to record nest visitation rates during chick feeding, and the sex was determined from nest video cameras. I also examine if the parents? rate of feeding visits changes over the nestling period.

Källskatt i ett EU-perspektiv : Diskriminering inom nationell rätt?

According to Swedish tax legislation, investment funds are taxed differently depending on if the are Swedish or foreign. The difference between the investment funds lies within the taxation of received dividends and the opportunity to shift the liability of tax of received dividends on to the funds shareholders. This measure is only available to Swedish funds. The question in this thesis is whether this difference is discriminatory against foreign investors and therefore constitutes a forbidden restriction against the free movement of capital stated in article 63 EUF Treaty.The European Court of Justice (ECJ) has given several preliminary rulings on this type of legislation and its compatibility with the principle of free movement of capital. It is not compatible with the free movement according to the court.

LAURA: Kognitiv beteendeterapi för kvinnor med psykisk ohälsa till följd av en traumatisk förlossning : En randomiserad kontrollerad studie av internetadministrerad vägledd självhjälpsbehandling

The purpose of this randomized controlled study was to investigate the effect of internet- administered guided self-help for women suffering from psychological problems following traumatic childbirth. The eight-week treatment program consisted of written chapters based on cognitive behavioral therapy. 56 participants were randomly assigned to a treatment group (n = 28) or a waiting list group (n = 28).The results showed that post-traumatic symptoms decreased as a result of the treatment, with large within-group effects measured by both the Traumatic Event Scale (TES) (d = 1.33) and the Impact of Event Scale-Revised (IES-R) (d = 1.3). The difference between the groups was only significant when measured by the IES-R in which case the between-group effect was large (d = 0.97). The proportion of the participants who showed clinically significant improvement was considerably greater in the treatment group than in the waiting list group.

"Om vi säger att mobbning inte förekommer i förskolan lurar vi oss  själva" : En intervjustudie om förskollärares föreställningar om barns maktrelationer och mobbning i förskolan

The study aims to describe and analyse the relationship between norm and practice regarding social services casework on honour-related problems. The relationship between norm and practice involves the difference between the way it is intended that social workers shall operate in these cases and how they perceive that this works in practice. We interviewed two focus groups of eight Swedish social workers, four in each group. We also held an individual interview with a social services business developer. Focus group interviews were based on two vignettes; one depicting an honour-related case and the second an "ordinary" case.

Hur livshistoriekaraktärer hos Europeisk abborre (Perca fluviatilis L.) påverkas av cykliska förändringar i populationsstrukturen

This report deals with life-history variation for Eurasian perch (Perca fluviatilis L.), with special emphasis on age and size at maturity in females, in perch populations that have changed in size distribution. The collection of fish samples was made with multimesh gill nets year 2011. The perch?s length, height, weight, status of gonads has been analyzed, and by observing the opercular bone the age has been determined. In two lakes close to Umeå in northern Sweden, Fisksjön and Ängersjön, the live-history traits of perch have been studied.

Intellectual Property Rights in Software : A Critical Investigation from an Ethical Perspective

The development of software was considered until the beginning of the 1990th as a cathedral like product development in closed companies. This way of development changed in the last decade. Open source software (OSS) development challenged this consideration significantly. OSS is produced in co-operation by skilled people, distributed and used by many moral agents. The result, the software itself, can be studied and modified.

Vattenvård vid slutavverkning : före och efter vattenvårdsutbildning på Stora Enso Skog, distrikt Siljan

In 2006, Stora Enso Skog implemented an education program in water management for harvester operators, timber purchasers, cut block planners and supervisors. The focus of the program was creating stream crossings with minimal harm to the stream and the surrounding riparian area. This main purpose of this study was to determine the difference in work procedures before and after participating in the program. The methodology consisted of field studies and interviews with harvester operators and their supervisors. The field study looked at how the streams had been crossed concerning the number of crossings, visible damage to the stream and/or the riparian area made by the machines. Biological parameters such as the width and dept of the stream and amount of large woody debris in the stream were also measured. The field result from 30 harvesting sites showed no significant difference between sites that had been harvested before or after the education program. But the harvester operators and their supervisors experienced an increased concern for watersheds after the educational program.

Effekter av kolhydraträkning vid diabetesdebut hos barn och ungdomar : En registerstudie

Abstract Aims and objectives. To examine whether an intervention with carbohydrate- counting at onset of type 1 diabetes in children, has had any effect on metabolic indicators such as HbA1c , BMI-sds and total daily insulin / kg, 2 months and 1 year after onset by age and gender .Background. The pediatric department at the university hospital of Norrland in Umeå (NUS), has since several years a higher average HbA1c among children 0-17 years, compare with pediatric departments in the rest of Sweden.  Therefore, in autumn 2011, an intervention was made to teach children with diabetes and their parents to count carbohydrates from the onset of diabetes. Using this method they can regulate their insulin doses depending on the amount of carbohydrates they are eating.Design.

Elitorienterares kost- och vätskeintag inför och under en tävlingshelg - Uppnår orienterarna rekommendationerna för optimal prestation?

För att en elitidrottare ska prestera optimalt under träning och tävling, är det viktigt att hon/han har en adekvat kosthållning. Särskilda näringsrekommendationer för idrottare har framarbetats. Bland annat har Svenska Olympiska Kommittén utarbetat en kostpolicy för elitidrottare, som belyser vikten av näringsintag före, under och efter fysisk aktivitet, samt hur dessa intag bör vara sammansatta näringsmässigt för att idrottaren skall kunna prestera och återhämta sig optimalt.Syftet med detta arbete var att se hur kost- och vätskeintaget såg ut bland elitorienterare före, under och efter tävling, i förhållande till gällande rekommendationer. Även livsmedelsval samt deltagarnas resonemang kring kost- och vätskeintag i samband med tävling studerades.Studiens urval baserades på 15 elitorienterare (8 män och 7 kvinnor) som deltog i orienteringstävlingar i Ronneby under påskhelgen. Orienterarna fyllde i en mat- och vätskedagbok under totalt fyra dagar, två dagar före respektive under tävlingshelgen.

Är korta spenar ett problem i samband med mjölkning? :

In some herds it has been observed that extremely short teats have become a problem; with a negative influence on the milking performance. The aim of this study was therefore to investigate to what degree the quality of the teats and the milk in cows with short teats is affected as compared with cows with normal teat length and furthermore if the milking performance could be improved by using a liner adapted to short teats. This study was divided in two parts. In the first part, it was examined if there were any differences between short teats and teats with normal length with reference to the milking performance, udder emptying, teat treatment, milk quality, and udder health. 11 pairs of cows were used and in each pair of cows one cow had teats shorter than 40 mm while the other cow had teats longer than 50 mm.

Motivation for eating roughage in sows : as an indiction of hunger

Today?s feeding methods can determine the domestic pig?s abilities to fulfill basic behavioral needs, such as foraging, and the way in which pigs are feed is an important aspect. Feed does not only provide the energy and nutrients critical for survival, but feeding is also associated with a number of other factors contributing to well-being and reproduction. Today the feed for gestated sows is often composed by high energy and low dietary fiber grain products such as wheat. Three kg of this kind of feed can often be consumed by the sow within 20 minutes.

Barn- och ungdomars uppfattning om sin övervikt och fetma som ett problem samt skillnader i aktivitetsnivån hos barn- och ungdomar beroende på deras sociala familjesituation

BackgroundIncreased prevalence of obesity in children- and young adults and risk for diseases related to obesity will increase the burden on medical care. It is important to identify early risk factors that can be noticed by nurses in the daily work.AimThe aim was to investigate whether children- and young adults themselves perceive overweight as a problem and if there was a difference in the measured activity levels between overweight children- and young adults in families with different socio-economic family status.Method descriptionExisting survey from the Obesity Centre at the Akademiska Sjukhuset were examined together with the results from an accelerometer, where children- and young adults activity was recorded, compared to their perception of how active they were. The results were compared using a statistical software program and compiled with descriptive and non-parametric statistics.ResultsThe results do suggest that the majority of children- and young adults experiencing excessive weight have a problem in their everyday lives. Nearly half overestimate themselves as more active than what the actual measurements with accelerometer demonstrated. Much time is spent in front of the TV and computers.
