Under the Kyoto agreement the signing members agreed to lower the emissions of green house gases, further on the EU has a 3-pillar strategy on carbon dioxide and cars. Included in the EU st

Problem discussion: Long-term supplier relationships have become more common. Hence, supplier evaluation is a critical activity for many companies. However, making a relevant supplier evaluation is time consuming. Therefore, it is important to decide which of the suppliers to put an extra effort on. Should all suppliers be evaluated in the same way? Previous, focus has been on purchasing of direct

Issue: To create a supporting IT-tool for project management in an integrated product development process at global companies is a complicated task. The IT-tool must be embedded in the organisation, managing the information flow in a correct way, support the product development framework, be accepted and commonly used in the whole company. These aspects must be fulfilled if an IT-tool for project

Aim: To investigate the problem of IT-users and IT-developers and their different abilities to use IT and communicate by means of IT, caused by differences in the background of the two categories, their knowledge and experience. Also to investigate what this problem may lead to when developing IT-related services and products. Method/material: Ten semi-structured interviews of about ten hours all

We report 17 new solar activity cycles with periodicities ranging from 1,700 to 18,000 years. Using Bayesian spectral analysis we determined for each cycle period, amplitude and phase for the past 145,000 years. These results were obtained by analyzing 10Be in the 2775 m long EDML ice core from Dronning Maud Land, Antarctica. In addition, we have augmented the 10Be data with synchronous ice accumu

Around one-fourth of the global population lacks access to clean fuels and technologies for cooking, most of them living in low- and middle-income countries. Reliance on rudimentary and inefficient biomass cookstoves results in high pollutant concentrations that adversely affect the health of those exposed to indoor air pollution, the environment, and the climate. In this study, we systematically

Organizations today embark on many changes internally and externally in order to strengthen ther

Tourism is an industry with considerable environmental and social impacts; in order to stimulate reduction of these impacts, voluntary recognition schemes i.e. ecolabels and certification programmes have been introduced to motivate tourism businesses to improve their environmental performance, encourage more sustainable practices and patterns in this branch of economy, provide information to touri

Three cases decided by the CFI, Airtours, Schneider Electric and Tetra Laval, along with the ECJ's judgement in the appeal of the Tetra Laval case, may have changed the way the Courts and the Commission approach questions of proof in the future. In these cases, the CFI did not hesitate to conclude: ''the contested decision does not establish to the requisite legal standard that the mod

Popular Abstract in Swedish "Behavioral Economics" är ett område inom nationalekonomin där forskningsresultat från främst psykologin inhämtas vid analys av ekonomiska fenomen, även om andra samhällsvetenskaper såsom socialpsykologi och sociologi också givit bidrag. Följande avhandling och dess fyra uppsatser undersöker delar av "Behavioral Economics" med särskild betoning på realism, ontologi och This thesis explores Behavioral Economics in terms of realism, ontology and experiments. In the introductory chapter descriptions of "Behavioral Economics", "realism" and "ontology" are offered. In the following three chapters meta-theoretical analyses are performed, while the fifth and last chapter is a report of an experiment but with a meta-theoretical undertone. In Chapter 2 two recent survey

Abstract in Danish Afhandlingens hovedproblemstillinger er: Hvilken betydning har det for danske socialarbejderes vurderinger og handlinger i børnefamiliearbejdet, at et barn og dets familie ikke er etniske danskere? Denne problemstilling undersøges gennem tre empiriske undersøgelser: Familieplejeundersøgelsen består af en journalundersøgelse af 44 anbragte etniske minoritetsbørns journaler samt The dissertation studies how social workers ensure continuity in relation to the individual child's background when placing and working with children of ethnic minority background in care. This is studied through 44 sets of case study notes from a foster-care association and interviews with 10 foster-care consultants. These two types of data are analysed through three perspectives: a continuity pe

We all live with Malaria - We just don’t know it Malaria is one of the world's biggest healthcare obstacles, taking the lives of millions and costing us millions. But what is Malaria? Malaria is an organism, more precisely a parasite, living at the expense of another organism. Even though the majority of humans have never had it, we have probably only been a few hundred meters away from indiv

Purpose: In this study, we examine the data from Chinese companies to test the relationship between cash flow and investment. While a wide assortment of previous research has examined the relationship between cash flow and investment, they have largely focused on empirical analysis from an US or a Western perspective. But, to date, little attention has been paid to such relationship using empirica

Syftet med studien är att bidra med kunskap om hur chefer och HR-medarbetare på ett energiföretag förväntar sig att onboarding med hjälp av artificiell intelligens (AI) skulle påverka deras arbetsmiljö. Onboarding är en viktig process för att en nyanställd snabbt ska bli en del av sin nya organisation och komma in i organisationens kultur. Det är framförallt chefer och HR-medarbetare som ansvarar The aim of the study is to contribute with knowledge about how managers and HR employees at an energy company imagine that an AI-based onboarding process would affect their organ- izational and social work environment from an efficiency and quality, social, and ethical per- spective. To answer the study's questions, the company Omexom, one of several companies in the energy sector that is expe

Att byggsektorn står inför ett rådande klimatnödläge är ett faktum. Idag investeras hundratals miljarder kronor för att i framtiden kunna producera fossilfritt stål; trots det läggs lite fokus på miljöoptimering av konstruktioner. Syftet med arbetet är att utvärdera hur parametrisk design kan användas som verktyg för att miljöoptimera stålstommar i industritrapptorn samt undersöka vilken profiltypThe fact that the construction sector faces a prevailing climate emergency is undeniable. Today, hundreds of billions of kronor are being invested to develop fossil-free steel; yet little focus is placed on environmental optimization of constructions. The purpose of this work is to evaluate how parametric design can be used as a tool for environmental optimization of steel staircase towers, as wel

Plastmaterial utgör ett betydande hot mot miljön, både på grund av sitt fossilbaserade ursprung och sitt bidrag till nedskräpningen av miljön. Detta examensarbete genomför en grundlig undersökning av Bhutans avfallshanteringssystem, med fokus på plast, i syfte att hitta de mest lovande alternativen för att förbättra hanteringen av avfall för att minska miljöproblemen och skapa en mer cirkulär ekonPlastic material poses significant threats to the environment, both due to their fossil-based origins and contribution to littering the environment. This master's thesis conducts a thorough investigation into Bhutan's waste management system, with a focus on plastics, aiming to find the most promising alternatives to improve the handling of waste for decreasing environmental issues and cre

Linjär lösning på ett icke-linjärt problem - effektiv filtrering i hornhögtalare Hornhögtalare är effektiva och skapar högt ljud men till priset av ljudkvaliteten. Genom linjär filtrering kan man få det bästa av två världar: minskade icke-linjära distorsioner och hög effektivitet. I vägen mot en säkrare värld spelar hornhögtalaren en viktig roll. Hornhögtalaren är förknippad med höga ljudnivåer This thesis aims to characterize and counteract the wave steepening effect in a horn loaded loudspeaker. The report consists of two main parts. The first part, the characterization of the horn speaker system, focuses on investigating and understanding the signal distortions introduced by the speaker system. In particular, non-linear distortion is examined to determine any parameter dependence of t

As climate change continues leads to rising global temperatures and poses the threat of extreme weather conditions, the cooling energy demand within the building sector is experiencing rapid growth. This study aims to compare both energy performance and cost efficiency between all-air cooling systems and water-based cooling systems by investigating variable air volume (VAV) system and ceiling radi

Att ta reda på hur och varför reaktioner sker molekyler emellan är ingen lätt uppgift. Ingen kamera är tillräckligt liten eller känslig (än) för att filma det som händer på molekylnivå. Istället behöver forskare genomföra experiment och samla stora mängder data för att få en bild av hur en reaktion går till, den så kallade reaktionsmekanismen. Att ta reda på reaktionsmekansimer ökar förståelsen föN-Acetylneuraminic acid (Neu5Ac) is the most common form of sialic acid, a nine-carbon sugar often situated at the ends of glycoconjugates. Its unique reactivity makes it a complex substrate to work on, but new methods are continuously developed. In 2007, Ye et.al. reported a regioselective substitution by morpholine on position 4 of fully acetylated Neu5Ac, with retained stereochemistry. The anom

Under en längre tid har EU-kommissionen utan framgång försökt införa en gemensam skattebas för koncerner som verkar inom EU. Det senaste för-söket, direktivförslaget BEFIT, presenterades 2023. Syftet med BEFIT är att införa bestämmelser som resulterar i en gemensam skattebas för större koncerner inom EU, att möjliggöra enklare gränsöverskridande resultatutjämning för dessa samt underlätta och effeFor a long time, the European Commission has unsuccessfully tried to in-troduce a common consolidated tax base for groups operating within the EU. The latest attempt, the directive proposal BEFIT, was presented in 2023. The purpose of BEFIT is to introduce regulations that result in a common consolidated tax base for larger groups within the EU, enable cross-border loss relief for these and reduce
