Regulatory approaches? influence on environmental agencies internal quality

The increasing public concern regarding the government?s priorities in spending public resources puts pressure on public organisations to address quality issues in their practice. In United Kingdom both BRTF (Better Regulation Task Force) (BIS, 2005b) and the Hampton report (BIS, 2005a) highlighted management and quality problems in public organisations in UK. These reports revealed obstacles within institutions? intent to offer recommendations and appropriate solutions for agencies working with legal enforcement and control.

Family or State? Communitarian Perspectives on Economic Responsibility for Unemployed Youth

At the beginning of the 21st century, youth unemployment is paid attention to by the Swedish government and media. A grand part of the unemployed youth live at their parents´ house because of economic reasons contrary to their primary goal to be able to make their own living. It can be argued that the young unemployed´ s social citizenship is inferior to working citizens´ social citizenship. The thesis will not deal with suggestions on practical solutions, but rather seek for theoretical answers to whether the responsibility for the young people referred to should be a responsibility of the State or of the family. Communitarianism is a relatively young theory which is interesting for this thesis because it sheds light on the dichotomy individual - community.

Sambandet mellan kondition och självskattad hälsa

ABSTRACT Background: Health and ill-health are multifaceted concepts. Previous research has shown that physical activity and the level of cardio respiratory are important parts of leading a healthy lifestyle. Possibly, it?s so important that the Occupational Health Service should focus even more on this.Aim: The aim was to investigate if there was a relationship between the level of cardio respiratory fitness and self-rated health, and between the level of cardio respiratory fitness and physical and mental ill-health.Method: The study was conducted using a quantitative method in the form of a cross sectional study. Data was collected from an Occupational Health Service, containing answers to a questionnaire on work environment and health and test values ??from completed cycle fitness tests.

Effektiviseringsmöjligheter på Tunadals sågverk : med innesäljarprocessen i fokus

The investigation was initiated because of the high workload of the sellers and, additionally, because the Tunadal sawmill has received low ratings in customer surveys. Thus,  two main approaches are adopted here,  the first being to investigate which of the three methods  of working, namely, market divided flow organization, function organizationand flow organization with collaboration, proves to be the most beneficial. The second is to investigate whether there is an available method to ease the daily work. A literature review has been made in order to determine more efficient ways for the sellers to work in the Tunadal sawmill. During the investigation, an in-depth investigation into the total quality management using a balanced scorecard as a management tool was conducted.

Managing Positions in a Dynamic Environment - New Technology Impact on Tactel and the Telecom Industry

The Telecom industry is facing a paradigm shift, where the industry is converging with Internet technologies and the market is becoming more sophisticated. This results in more demanding customers, and the need for offering more content and services with a focus on usability for the end-users. The operators are starting to loose both their strong position and revenue in the Telecom industry, due to new technology and the fact that other actors are starting to enter the market, offering new content and services. In the end, the operators have two choices, to become bit-pipe providers, and only focusing on network management, or keeping the control over their networks. The latter would mean that they block other actors who are taking parts of their revenue, e.g.

Energieffektivisering av aerbo reningsprocess : Tillsats av biprodukter i skogsindustriellt avloppsvatten

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

Finns det rätta livsmedelsvalet?

Outdoor recreation habits in metropolis and rural areasThis study aims to examine the perception of nature and outdoor recreation habits from an urban-rural prospective. The urbanization process continues in Sweden and the populations of the cities are growing continuously. Trends to build more compact and ?climate smart? reigns and with this a risk that green areas and areas where outdoor recreation can be practiced are situated further and further away from the urban population. Analyzing the responses from a survey made by the research program Friluftsliv i förändring 2007 we have examined if and which differences exists between urban and rural areas regarding their perception of nature, outdoor recreation habits and factors influencing the practice of outdoor recreation.

Autumn water sources for understory vegetation and fungi in a boreal forest : an evaluation using stable isotopes

Understory vegetation and fungi are regarded as important ecological drivers of processes like productivity and nutrient cycling in boreal forests. Whilst those processes are linked to soil water content, relatively little is known about the sources of soil water for these forest components. During early autumn in boreal forests, temperature falls and large events of rain are frequent which may influence soil water availability. To better understand the autumn plant-soil-fungi water relationships in this ecosystem, I used stable isotopes techniques in this study to examine the water sources for ericaceous shrubs and fungi in a Scots pine forest following a large, early autumn rain event. I hypothesize that ericaceous shrubs of two functional groups (evergreen vs.

Äggstockscysta hos mjölkkor

The presence of cystic ovarian follicles represents an important ovarian dysfunction and is a major cause of reproductive failure in dairy cattle. A cystic ovarian follicle is a persistent follicular-like structure on one or both of the ovaries. It is at least 2,5cm in diameter and it has to persist for at least ten days while a corpus luteum is missing. There are two kinds of cystic ovarian follicles, those who have a progesterone production and those who have not. A clear definition for this condition is lacking, probably because the heterogeneity of the clinical signs and the complexity of the disorder.

Frystorkning Kontrollerad torkning av kulturhistorisk dräkt?

Cultural objects may become wet by deliberate water cleaning, water disaster or watersoaked for other reasons. Air drying textile objects and even other organic materials from awater wet state, involves many problems depending on the strong capillarity action of water.Damages and changes such as bleeding of dyes, stains or lines of impurities from watermovement, shrinking or stiffness can occur. Freeze-drying as an alternative drying methodhas often been used for wet archaeological and marine objects, but more seldom for historicalmaterials.This bachelor thesis addresses the issue of whether freeze-drying can be an alternative controlleddrying method for historic costumes. Costumes and related objects are often compositeobjects, consisting of multiple materials, as well as being three dimensional, all of whichwill complicate drying. The purpose of this study was to investigate whether it is possible tohandle costume objects after wet cleaning for drying by freeze-drying, and if damages due tosurface tension of water, can be avoided in this way.

Fertility before and after installation of Herd Navigator?

The fertility of dairy cows is of great importance in order to maintain high production. The decline in fertility of dairy cows the latest decades can have several explanations. The large emphasis on high yielding cows and the negative genetic correlation between milk production and fertility traits could be one of the main factors for impaired fertility. To find heats and inseminate the cow at the right time is crucial to receive high conception rate. Delaval has, in corporation with FOSS, developed Herd Navigator which is a management program that measure four biological parameters in the milk; progesterone, betahydroxybutyrate, lactate dehydrogenase and urea.

En miljo?ja?mfo?relse av traditionellt stambyte kontra relining av tappvattenro?r : Med hja?lp av livscykelanalys

This study was a final thesis, for the bachelor program in civil engineering at theUniversity of Uppsala, which was made on behalf of Riksbyggen in Uppsala. Acomparative study of two stain renovation methods; tradition pipe replacement andrelining was done with an environmental perspective. A simplified life cycleassessment (LCA) was done according to the International Organization ofStandardization (ISO) with the LCA tool Eco-indicator 99, in order to be estimate theimpact on the environment. LCA is a method that follows a product or a system?from the cradle to the grave?, which means that all the environmental impact over alifetime is considered.The work was executed by using a stairway with nine apartments in a house called?Uppsala Hus 9? as a reference object, which was provided by Riksbyggen.

Konstruktionstudie av en ångexpander

This thesis applies to a novel steam expander, one part of a steam engine system, a wobble plateengine. The piston in the expander moves axially with the outgoing rotating shaft and is locatedon a plate, why the engine type is called axial engine. When steam is applied to the plungers theplate wobbles creating a rotation on the shaft going thru the wobble plate. The steam expander issupposed to be used in exhaust gas recovery (bottoming cycle) applications and small scaleenergy production. The commissioner is Ranotor Utveckling AB.

Honlig reproduktionsfysiologi hos lodjur (Lynx lynx)

Knowledge in reproduction in the Swedish lynx (Lynx lynx) is important forseveral reasons. Situated on top of the food chain, lynxes may be at risk of beingexposed to environmental toxins that could have adverse effect on reproduction.The population of lynxes is today managed by restricted hunting which demandsknowledge about both the lynxes numbers and their reproduction. In addition,lynxes may function as indicators of climate change for instance if their season ofheat would be earlier or prolonged due to a warmer climate. Today?s knowledgein reproduction in Swedish lynx is mainly based on information gathered fromradio collared animals.

Surhetstillståndet i bäckar uppströmskalkdoserare i Dalarnas län

The acid deposition of sulphur- and nitrogenoxides from combustion of coal and oil cause acidification that lowers pH and gives increased contents of metals and altered aquatic biodiversity in the stream. The liming of lakes and streams, which was introduced to resist the acidification, demand large economic resourses despite of the decreased deposition of the acidifyng substances. Some of the streams are influenced by the acid deposition, while others are naturally acidic. It is therefore importaint to separate the anthropogenically acidified waters from the naturally acidic, in order to optimize the use of governmental fundings for liming. This thesis aims to estimate the acidity status and impact of acidification on 24 catchments upstream liming dispensers, which is part of the liming activities at the County of Dalarna.The acidity status of the streams was classified according to the Swedish Environmental Protection Agency old classification system (Naturvårdsverket 1999) as very acid to acid, with small ability to withstand a pH-change (alkalinity) due to acid deposition.
