Syftet med denna uppsats är att undersöka vilken roll Facebook spelar för tonåringar i deras identitetsskapande. Syftet uppnås genom följande övergripande frågeställning: • Hur ser relationen mellan tonåringars användning av Facebook och deras identitetsskapande ut? Den i sin tur mynnar ut i två följdfrågor: • Vilken typ av behov fyller Facebook för tonåringar? • Hur yttrar sig ett sådant behov
Då mobila system utvecklas, finns det ett antal aspekter som bör tas hänsyn till i denna process, för att den mobile användaren ska få ett så komplett verktyg som möjligt att arbeta med. I vår studie har vi, med utgångspunkt ifrån Task Closure Theory, studerat huruvida ett mobilt system behöver kompletteras med stödjande teknik. Vi har i denna uppsats undersökt aspekten om support technologies (st
After the Arab spring, states in the MENA-region that were enrolled in the popular uprisings are now entering different settings. Some have been more successful, and reaching all the way to democratic consolidation. Others like Egypt are currently experiencing severe backlashes. In this post revolution context, time is starting to run out for an escape out of the transitional maze. Tunisia is not
In phase-change memory devices, a material is cycled between glassy and crystalline states. The highly temperature-dependent kinetics of its crystallization process enables application in memory technology, but the transition has not been resolved on an atomic scale. Using femtosecond x-ray diffraction and ab initio computer simulations, we determined the time-dependent pair-correlation function o
Mountain communities are adapting their livelihoods to a complex combination of social, political and economic changes and associated risks. Despite recognition of adaption in response to multiple changes in sustainable livelihood and critical climate change literature, risks attributed to biophysical effects of climate change have increasingly assumed importance. Consequently, diversification is
For several centuries, the dominant worldview in industrial societies has held that various problems --such as those recently identified as relating to sustainability-- can be solved through technological progress. Technological progress has been conceived as the fruits of engineering science, new knowledge, and innovation. While knowledge of the principles of physics is certainly a necessary cond
Although teachers’ well-being and vocal health are affected by noise, research on classroom sound environment from the teachers’ perspective is scarce. This study investigated the relationship between teachers’ well-being and classroom acoustics. The possible influence of teachers’ age, experience, teaching grade and class size on the relationship was also investigated. In this study, well-being r
This paper investigates potential factors that control the El Niño–Southern Oscillation (ENSO) Spring Persistence Barrier (SPB) strength in two different ENSO regimes and apply it to explain the ENSO SPB strength modulation after the 21st century. In a damped, noise-driven model, the theoretical solution of SPB strength illustrates that a weaker ENSO growth rate strengthens SPB. In the self-sustai
Applying pre-processing and geometric transformation, for the generalization of building blocks, can lead to spatial conflicts which are mainly resolved by displacement. However, the conflicts may not be resolved, due to the insufficient space for displacement or the existence of other objects that prevent displacement. This article proposes a novel model combining building block displacement and
This paper provides an empirical analysis of the effectiveness of real-time feedback technology in the Swedish residential sector. We take the ‘100Koll’ service provided by one the largest energy companies in Sweden as a case study. Based on an intervention group (i.e. people using the service) of 1 753 households, a survey was carried out to explore behavioural, moral, socio-economic and contextu
Governance of common resources such as water calls for rethinking structure, legal frameworks and property rights. In order to promote the decentralization of water governance, Water User Associations (WUAs) were created in many countries, such as India and Turkey, to operate and maintain irrigation systems as well as take over the responsibility of water distribution among water users. Despite pr
The lifetimes of 17 even-parity levels (3d5s, 3d4d, 3d6s and 4p2) in the region 57 743–77 837 cm−1 of singly ionized scandium (Sc ii) were measured by two-step time-resolved laser induced fluorescence spectroscopy. Oscillator strengths of 57 lines from these highly excited upper levels were derived using a hollow cathode discharge lamp and a Fourier transform spectrometer. In addition, Hartree–Foc
This chapter presents a socio-historical perspective on the origin and development of the Swedish school field and the teaching professions. With Bourdieu as a source of inspiration, the school field is defined as a system of specialized institutions and agents (church, state, academy, teachers’ unions) who, based on different interests and positions, compete for recognition and power to define th
The global carbon cycle is an important component of the Earth system and it interacts with the hydrology, energy and nutrient cycles as well as ecosystem dynamics. A better understanding of the global carbon cycle is required for improved projections of climate change including corresponding changes in water and food resources and for the verification of measures to reduce anthropogenic greenhous
