Dalarna University is a university college located in Falun and Borlänge, in Dalarna County, Sweden.Dalarna University is one of Sweden’s more recent institutions of higher education, established in 1977. It is situated in Dalarna, 200 kilometres north-west of Stockholm.The college currently has about 18000 students. Approximately half of them study in Falun, the administrative capital of the province, while the rest study in the neighbouring town of Borlänge and via distance education. Wikipedia.

Traditional methods for detecting genes that affect complex diseases in humans or animal models, milk production in livestock, or other traits of interest, have asked whether variation in genotype produces a change in that trait's average value. But focusing on differences in the mean ignores differences in variability about that mean. The robustness, or uniformity, of an individual's character is not only of great practical importance in medical genetics and food production but is also of scientific and evolutionary interest (e.g., blood pressure in animal models of heart disease, litter size in pigs, flowering time in plants). We describe a method for detecting major genes controlling the phenotypic variance, referring to these as vQTL. Our method uses a double generalized linear model with linear predictors based on probabilities of line origin. We evaluate our method on simulated F2 and collaborative cross data, and on a real F2 intercross, demonstrating its accuracy and robustness to the presence of ordinary mean-controlling QTL. We also illustrate the connection between vQTL and QTL involved in epistasis, explaining how these concepts overlap. Our method can be applied to a wide range of commonly used experimental crosses and may be extended to genetic association more generally. © 2011 by the Genetics Society of America. Source

This paper presents the development and evaluation of a method for enabling quantitative and automatic scoring of alternating tapping performance of patients with Parkinson's disease (PD). Ten healthy elderly subjects and 95 patients in different clinical stages of PD have utilized a touch-pad handheld computer to perform alternate tapping tests in their home environments. First, a neurologist used a web-based system to visually assess impairments in four tapping dimensions ('speed', 'accuracy', 'fatigue' and 'arrhythmia') and a global tapping severity (GTS). Second, tapping signals were processed with time series analysis and statistical methods to derive 24 quantitative parameters. Third, principal component analysis was used to reduce the dimensions of these parameters and to obtain scores for the four dimensions. Finally, a logistic regression classifier was trained using a 10-fold stratified cross-validation to map the reduced parameters to the corresponding visually assessed GTS scores. Results showed that the computed scores correlated well to visually assessed scores and were significantly different across Unified Parkinson's Disease Rating Scale scores of upper limb motor performance. In addition, they had good internal consistency, had good ability to discriminate between healthy elderly and patients in different disease stages, had good sensitivity to treatment interventions and could reflect the natural disease progression over time. In conclusion, the automatic method can be useful to objectively assess the tapping performance of PD patients and can be included in telemedicine tools for remote monitoring of tapping. Source

Aim: The aim of this study was to illuminate and clarify the concept of existential issues in relation to nursing research and nursing practice. Methods: This article is a theoretical analysis of existential issues in relation to nursing. Results: Existential issues are becoming more commonly discussed and investigated in nursing research. Thus, it is important to clarify the concept. Conclusions: A clarification of existential issues may contribute to health care quality by increasing awareness of what existential issues are and drawing attention to the importance of discussing and reflecting on these issues, since practitioners in a caring profession will most likely encounter them. © 2014 Elsevier Ltd.

Emotions such as guilt and blame are frequently reported by non-breastfeeding mothers, and fear and humiliation are experienced by breastfeeding mothers when feeding in a public context. In this paper, we present new insights into how shame-related affects, cognitions and actions are evident within breastfeeding and non-breastfeeding women's narratives of their experiences. As part of an evaluation study of the implementation of the UNICEF UK Baby Friendly Initiative Community Award within two primary (community based) care trusts in North West England, 63 women with varied infant feeding experiences took part in either a focus group or an individual semi-structured interview to explore their experiences, opinions and perceptions of infant feeding. Using a framework analysis approach and drawing on Lazare's categories of shame, we consider how the nature of the event (infant feeding) and the vulnerability of the individual (mother) interact in the social context to create shame responses in some breastfeeding and non-breastfeeding mothers. Three key themes illustrate how shame is experienced and internalised through 'exposure of women's bodies and infant feeding methods', 'undermining and insufficient support' and 'perceptions of inadequate mothering'. The findings of this paper highlight how breastfeeding and non-breastfeeding women may experience judgement and condemnation in interactions with health professionals as well as within community contexts, leading to feelings of failure, inadequacy and isolation. There is a need for strategies and support that address personal, cultural, ideological and structural constraints of infant feeding. © 2014 John Wiley & Sons Ltd. Source

In this work, I consider the center-of-mass wave function for a homogenous sphere under the influence of the self-interaction due to Newtonian gravity. I solve for the ground state numerically and calculate the average radius as a measure of its size. For small masses, M≲10 -17 kg, the radial size is independent of density, and the ground state extends beyond the extent of the sphere. For masses larger than this, the ground state is contained within the sphere and to a good approximation given by the solution for an effective radial harmonic-oscillator potential. This work thus determines the limits of applicability of the point-mass Newton Schrödinger equations for spherical masses. In addition, I calculate the fringe visibility for matter-wave interferometry and find that in the low-mass case, interferometry can in principle be performed, whereas for the latter case, it becomes impossible. Based on this, I discuss this transition as a possible boundary for the quantum-classical crossover, independent of the usually evoked environmental decoherence. The two regimes meet at sphere sizes R≈10 -7 m, and the density of the material causes only minor variations in this value. © 2012 American Physical Society. Source
