In this licentiate thesis, I explore how two theoretical frameworks—social semiotics and the variation theory of learning—used in physics education research, can be fruitfully combined to obtain additional analytical tools for analysing student learning in introductory level university physics. Each theoretical framework has on their own, or together with other frameworks, been successfully applie

Popular AbstractI början på 1990-talet drabbades Sverige av en mycket djup ekonomisk kris. Den svenska nittiotalskrisen uppfattades inte som en tillfällig konjunkturnedgång utan som symptom på grundläggande systemfel i Sveriges ekonomi. Många bedömare menade att den s.k. svenska modellen med stor välfärdsstat och höga skatter hade försämrat marknadsekonomins effektivitet och gjort att Sverige undeIn the early 1990s, Sweden was hit by a profound economic crisis. The Swedish crisis of the nineties was not perceived as a temporary recession, but rather as a fundamental and systemic fault in Swedish economy. Many commentators held that the Swedish model with a large welfare state and high taxes had impaired Sweden's economic performance. The aim of this thesis is to empirically assess the hypo

The pulp and paper industry is one of the most important industrial sectors worldwide. The focus of current pulp mills is on the production of cellulose pulp fibres and electricity. By converting traditional pulp mills into biorefineries they can be a keystone in a future bioeconomy based on renewable resources instead of fossil fuels. In order to achieve this, pulp mills have to close their loops

Denna kunskapssammanställning beskriver hur hälsoskadlig värme kan uppstå inomhus, hur den kan identifieras och vilka åtgärder som kan vidtas med fokus på fastighetsägarens ansvar. Sammanställningen är begränsad till befintliga byggnader i Sverige och inkluderar skolor, äldreboenden, lägenheter, förskolor och kontor som är icke-industriella (utan industriella processer som producerar värme). Den pThis literature review describes how heat stress can develop indoors, how it can be identified, and what actions can be taken, with a focus on property owner’s responsibilities. The review is limited to existing buildings in Sweden and includes schools, retirement homes, apartments, preschools, and non-industrial offices (those without industrial processes that produce heat). The expected climate

I tidigare forskning om krig presenteras ofta ensidiga bilder av fenomenen krigsvåld, offerskap och försoning. Denna bok utgår från berättelser av överlevande efter kriget i Bosnien under 1990-talet. Syftet är att analysera hur de intervjuade beskriver dessa fenomen samt vilka diskursiva mönster som framträder i konstruktionen av begreppen ”offer” och ”förövare”. Mina frågeställningar är: Hur beskThis book analyzes verbally depicted experiences of survivors from the war in Bosnia and Herzegovina. One purpose to describe how the actors portray the social phenomenon of “war violence” “victimhood” and “reconciliation”, and the second aim is to analyze discursive patterns that emerges in the creation of the terms “victim” and “perpetrator”. My research questions are: (1) How do the interviewee

Antal fordon i trafiken börjar bli allt fler och fler. Detta leder till att vägar behöver underhållas emellanåt. För att åtgärda vägarna så krävs det vägarbetare på plats, 90% av dessa vägarbetare känner oro dagligen på sitt jobb. Anledningen till deras oro är att många trafikanter inte tar någon hänsyn till vägarbetare, de kör aggressivt, hänsynslöst och över hastighetsgränsen. Under åren 2003-20The number of vehicles in traffic is increasing. This means that roads need to be maintained regularly. To repair the roads, road workers are required on site. Ninety percent of these road workers feel anxious daily at their work. The reason for their concern is that many road users do not pay any attention to road workers, they drive aggressively, ruthlessly and over the speed limit. During the y

It is now allowed to sell mealworm (Tenebrio molitor) for food consumption, and it will probably play a major role in the search for future protein sources. The climate footprint of the mealworm is considerably smaller than for traditional livestock and is therefore of interest. Insects as human food is fairly unexploited in Sweden and the western world. In connection with the new legislation, an

With the book The Theory of the Growth of the Firm, published in 1959, takes the researcher Edith Penrose the first step towards what will later be known as the resource based view. Many scholars have since taken up where Penrose left and has further developed the approach to something that can now be described as almost a philosophy. Today is the resource based view synonymous with an internal fo

På Siciliens östkust strax söder om Syrakusa, ligger ett långsmalt naturområde som följer kusten längs halvön Maddalenas sydspets ut till udden Capo Murro di Porco. Det är en obebyggd kustremsa sånär som på en fyrbyggnad med två angränsande stenhus. Naturen domineras av det klippiga landskapet och de tre byggnaderna som kommit att smälta in i omgivningen. I detta arbete, som är en fallstudie som Capo Murro di Porco is situated in a narrow natural area that runs along the coast of the peninsula of Maddalena, just south of Syracuse on the east coast of Sicily. It is an area of stunning nature with dramatic topography, steep cliff sides and sparse vegetation. On the very line marking the transition from low vegetation to bare rock on the horn of the peninsula, a lighthouse and two rugged low

En nyligen utgiven studie från Södersjukhusets Akutmottagning för våldtagna visar att 70 procent av de tillfrågade våldtäktsoffren hade hamnat i ett tillstånd av frozen fright under övergreppet. Att ett offer hamnar i ett frystillstånd, frozen fright, innebär att förmågan att röra sig eller ge ljud ifrån sig minskas eller försvinner helt eftersom offrets utsätts för en traumatisk upplevelse. DennaA recently published study from Stockholm South General Hospital Emergency Clinic for Rape Victims shows that 70 per cent of the questioned victims had experienced a state of frozen fright during the rape. Frozen fright means a diminished or absent volitional movement accompanied by diminished vocal capacity in response to a traumatic event. The purpose of this thesis is to examine the perceptions

In the middle ages the Albanian northern tribes had their own customary law that regulated their everyday life. This customary law is called the Kanun of Lekë Dukagjini. The Kanun of Lekë Dukagjini has been passed on by the old generation orally to new generations and used by highland clans in northern Albania, Kosovo and from Albanian tribes in Macedonia and Montenegro. This oral law regulates cr

Sverige står inför en betydande utmaning i att minska sina utsläpp av växthusgaser för att nå det nationella klimatmålet om nettnollutsläpp till år 2045. För bygg- och anläggningssektorn innebär detta en omfattande omställning, där alla aktörer i branschen aktivt behöver bidra för att målet ska kunna uppnås. I dagsläget är sektorn en av de större källorna till Sveriges koldioxidutsläpp vilket inneSweden faces a significant challenge in reducing its greenhouse gas emissions in order to reach the national climate goal of net-zero carbon emissions by 2045. For the construction sector, this requires a major transformation where all actors must actively contribute for the goal to be achieved. Currently, the sector is one of the largest contributors to Sweden’s carbon dioxide emissions, making m

I dagsläget äger nästan alla vuxna svenskar finansiella instrument. Det är vidare allmänt känt att sparande i finansiella instrument inte är helt riskfritt. För många individer är besparingarna väldigt viktiga, samtidigt som många saknar den kunskap som krävs för att investera i finansiella instrument. Behovet av finansiell rådgivning har därför ökat kraftigt, varför det får anses oroväckande att Almost all Swedish adults own financial instruments. It is well known however that investing in financial instruments is not risk free. Furthermore, these investments are often very important for many individuals, but most people lack the necessary knowledge required to invest in financial instruments. There has therefore been a strong increase in the need for financial advisers. With regard to th

In a progressively globalized world the catapults of economic globalization, is in large, due to increased flows of foreign direct investments (FDI) across the world. FDI flows are considered essential vehicles for economic growth and development. The complex entities that embody a multinational company (MNC ) are often simplified to encompass either an exploitation approach of LDCs by MNCs or the

Det här examensarbetet behandlar den akustiska utformningen av simhallar. Fokus ligger på de lösningar som påverkar akustiken, så som väggar, absorbenter och utformningen. Grunden till arbetet är baserat på befintlig litteratur och ny information framtaget för arbetet. Simhallar är en svår akustisk lokal där många hårda ytor och stora volymer försvårar. Detta ger en ljudmiljö med hög ljudnivå ochThe Master thesis considers acoustic design of swimming halls.

In today’s railway facilities there are several types of track systems with different characteristics, which must interconnect in order to obtain a closed network. The area where a track system passes over into another track system is called a transition zone. The track systems’ different characteristics chiefly consist of differences in settlement tendency and track stiffness. The transition zone

Background For companies’ long term survival it is essential to manage product rollovers successfully. It can even be more important than the product development in some cases. Unfortunately, most companies experience less than successful product rollovers. Several difficulties can jeopardise a successful rollover, such as: technical problems that can delay a new product introduction, excess prod
