BackgroundPeople with intellectual disability have been found to have higher prevalence of psychiatric disorders than the general population. However, they do not seem to have a corresponding increase in psychiatric care utilization. The aim of the present study was to investigate psychiatric care utilization among older people with intellectual disability.MethodsWe used a cohort of people with in

Solvents are commonly used in pharmaceutical and cosmetic formulations and sanitary products and cleansers. The uptake of solvent into the skin may change the molecular organization of skin lipids and proteins, which may in turn alter the protective skin barrier function. We herein examine the molecular effects of 10 different solvents on the outermost layer of skin, the stratum corneum (SC), usin

The harm that pathogens cause to hosts during infection, termed virulence, varies across species from negligible to a high likelihood of rapid death. Classic theory for the evolution of virulence is based on a trade-off between pathogen growth, transmission and host survival, which predicts that higher within-host growth causes increased transmission and higher virulence. However, using data from

Energy consumption reduction is today an important design issue for all kinds of digital systems. Offering both flexibility and efficient energy management, variable speed processor architectures are prefered for low energy consumption even in hard real-time systems. For this type of systems, the main approach consists in trading speed for lower energy while meeting all deadlines. For tasks with v

In our research we investigate rational agent which consciously balances deliberation and acting, and uses learning to augment its reasoning. It creates several partial plans, uses past experience to choose the best one and, by executing it, gains new knowledge about the world. We analyse a possible application of Inductive Logic Programming to learn how to evaluate partial plans in a resource-con

Popular Abstract in Swedish Bakgrund Avsikten med denna studie har varit att värdera om det idag föreligger tecken som tyder på att utvecklingen av diagnostiska hjälpmedel och behandlingsmetoder vid cancer i bukspottkörteln har åtföljts av en förbättrad prognos, samt att värdera vilken roll rökning och magsårsoperation kan ha för uppkomsten av sjukdomen. Pancreascancer, cancer i bukspottkörteln, The objective of this thesis has been to assess whether there are indications suggesting that new methods for diagnosis and treatment of pancreatic carcinoma (PCa) has been followed by an improved prognosis, and to assess the possible role of smoking and gastric resection in the causation of the disease. Of the 1,200 new cases PCa diagnosed in Sweden yearly, the majority are older than 70 years,

Popular Abstract in SwedishDenna studie utgår från tanken att ett samhälle kan ses som en grupp individer förenade i ett nätverk av sociala relationer. Nyckeln till förståelsen av samhället ligger därför i studiet av dessa sociala nätverk som den praktik (mikronivå) vari de sociala strukturerna (makronivån) reproduceras och förändras.Syftet med studien är att utifrån de sociala nätverken studera hThe aim of the study is to examine, using the social networks as a starting-point, the way a local community is constructed in a specific historical context, namely the industrial community of Limhamn in southern Sweden at the time of the Industrial Revolution 1870-1914. In 1870 the Skånska Cement Company initiated a large-scale extraction of limestone in the area and soon had cement works built i

The attitude of teachers towards students can vary substantially in relation to different factors, such as educational background, pedagogical training, teaching methods, etc. In this paper, we explore the impact of negative role-models on future teaching. In particular, past experiences of teachers as students as well as the contextual influence of other teachers on their future teaching has been

This paper is a component of a three-year empirical study of gaming moms undertaken with the aim to modulate the conventional constructions of gamer identities and examine the contested status of gaming in everyday life. It presents samples of mothers in gaming discourse – from TV, Music-video, forums, and ads. Mothers have been largely invisible in popular gaming discourse or formulaically portra

The project combines the highly sensitive salt(NaCl) dosemeter for photon radiation with a neutronphotonconverter in the form of thin gadolinium foilsenclosing the salt. Using an identical salt dosemeter butwithout gadolinium cover determines the primaryphoton contribution. With these twin dosemeters placedin a polyethylene sphere, both photon and neutron dosecontributions can be estimated. This p

The role of auditory feedback in vocal production has mainly been investigated by altered auditory feedback (AAF) in real time. In response, speakers compensate by shifting their speech output in the opposite direction. Current theory suggests this is caused by a mismatch between expected and observed feedback. A methodological issue is the difficulty to fully isolate the speaker’s hearing so that

Crystals, nanoparticles, and fibrils catalyze the generation of new aggregates on their surface from the same type of monomeric building blocks as the parent assemblies. This secondary nucleation process can be many orders of magnitude faster than primary nucleation. In the case of amyloid fibrils associated with Alzheimer's disease, this process leads to the multiplication and propagation of aggr

Climate change affects organisms worldwide with profound ecological and evolutionary consequences, often increasing population extinction risk. Climatic factors can increase the strength, variability, or direction of natural selection on phenotypic traits, potentially driving adaptive evolution. Phenotypic plasticity in relation to temperature can allow organisms to maintain fitness in response to

How did human symbolic behavior evolve? Dating up to about 100,000 y ago, the engraved ochre and ostrich eggshell fragments from the South African Blombos Cave and Diepkloof Rock Shelter provide a unique window into presumed early symbolic traditions of Homo sapiens and how they evolved over a period of more than 30,000 y. Using the engravings as stimuli, we report five experiments which suggest t

Background: Home care service (HCS) for sick children is a complex healthcare service, which can be organised in various models. Despite the possibility to support family everyday life, the accessibility and utilisation may still be limited. The aim of this study was to (i) determine characteristics in referrals to county-based HCS, (ii) determine characteristics of referred children and (iii) ass

Streptococcus pyogenes is an important human pathogen frequently colonizing the throat and skin of humans. To facilitate colonization and spread and to avoid the host immune defence, streptococci are endowed with a variety of virulence factors, two of which are investigated in this thesis namely streptolysin O (SLO) and M protein. SLO is a secreted cytolysin that forms pores in eukaryotic membran

The respiratory pathogen Moraxella catarrhalis is a human-specific commensal that frequently causes acute otitis media in children and stimulates acute exacerbations in chronic obstructive pulmonary disease patients. The exact molecular mechanisms defining host-pathogen interactions promoting pathogenesis are not clearly understood. Limited knowledge hampers vaccine and immunotherapeutic developme
