- The archaeological documentation of the development of sedentary farming societies in Anatolia is not yet mirrored by a genetic understanding of the human populations involved, in contrast to the spread of farming in Europe [1-3]. Sedentary farming communities emerged in parts of the Fertile Crescent during the tenth millennium and early ninth millennium calibrated (cal) BC and had appeared in central Anatolia by 8300 cal BC [4]. Farming spread into west Anatolia by the early seventh millennium cal BC and quasi-synchronously into Europe, although the timing and process of this movement remain unclear. Using genome sequence data that we generated from nine central Anatolian Neolithic individuals, we studied the transition period from early Aceramic (Pre-Pottery) to the later Pottery Neolithic, when farming expanded west of the Fertile Crescent. We find that genetic diversity in the earliest farmers was conspicuously low, on a par with European foraging groups. With the advent of the Pottery Neolithic, genetic variation within societies reached levels later found in early European farmers. Our results confirm that the earliest Neolithic central Anatolians belonged to the same gene pool as the first Neolithic migrants spreading into Europe. Further, genetic affinities between later Anatolian farmers and fourth to third millennium BC Chalcolithic south Europeans suggest an additional wave of Anatolian migrants, after the initial Neolithic spread but before the Yamnaya-related migrations. We propose that the earliest farming societies demographically resembled foragers and that only after regional gene flow and rising heterogeneity did the farming population expansions into Europe occur.

- Patients with Parkinson’s disease that may benefit from device-assisted therapy can be identified with guidelines like Navigate PD. The decision to offer advanced treatment and the choice of treatment modality are, however, not straightforward, and some patients respond less favorably to a chosen therapy. Measurements with the Parkinson Kinetigraph (PKG) can detect motor fluctuations and could therefore predict patients that respond better or worse to intestinal levodopa/carbidopa gel infusion (LCIG). In a retrospective analysis of 45 patients that had been selected to start LCIG between 2014 and 2020, the effects of baseline PKG and clinical characteristic on the outcome were determined with ordinal regression. Although all patients had been found to have handicapping medication-related symptom fluctuations, patients without clear objective off fluctuations in the baseline PKG had low odds ratio for success. Lower odds for success were also found with increasing age, whereas gender, medication intensity and baseline PKG summary scores (median bradykinesia and dyskinesia scores, fluctuation dyskinesia score and percent time with tremor) had no significant effect. Absence of easily identified off-periods in the PKG has a negative prognostic value for the effect of LCIG and could prompt noninvasive infusion evaluation before surgery. © 2022 by the authors.

TEM-wave propagation in a parallel plate waveguide with impedance-matched RHM to LHM transition

- We study TEM-wave propagation in a parallel plate waveguide with a graded transition between a lossy right-handed material (RHM) and an impedance-matched lossy left-handed material (LHM). The transition between the two media is graded along the direction perpendicular to the boundary between the two materials, and the permittivity and permeability vary according to hyperbolic tangent functions. We obtain exact analytical solutions to Maxwell's equations for lossy media, and the solutions for the field components confirm the expected properties of RHM-LHM structures. Finally, we perform a numerical study of the wave propagation over an impedance-matched graded RHM-LHM interface, using COMSOL, and obtain an excellent agreement between the numerical simulations and analytical results.

How Can Safer Care Be Achieved? : Patient Safety Officers’ Perceptions of Factors Influencing Patient Safety in Sweden

- Objective This study aimed to survey health care professionals in Sweden on the factors that they believe have been most important in reaching the current level of patient safety and achieving safer care in the future as well as the characteristics of the county councils that have been the most successful in achieving safe care.Methods The study population consisted of 222 patient safety officers, that is, health care professionals with strategic positions in patient safety work in the county councils. A postal questionnaire was used for data collection.Results The survey response rate was 70%. The factors that were considered most important for the current level of patient safety were efforts to reduce the use of antibiotics; Swedish patient safety law; and internal discussions with the county council management, heads of health care units, health care providers, and so on. The factors that were considered most important to achieve safer care in the future were improved communication between health care practitioners and patients, improved organizational culture, improved communication, and patient safety knowledge as a compulsory component of basic education for health care practitioners.Conclusions Several factors rated highly for achieving the current level of patient safety are part of the government-supported financial incentive plan. Patient safety is attributed to a broad range of factors, and many solutions might contribute to improved patient safety in the future. The most successful county councils are characterized by leadership support for patient safety, well-organized patient safety work, long-term commitment to patient safety, and an organizational culture that is conducive to patient safety.

- Two methods (including randomization) are studied for increasing the uncertainty concerning n ³ 1 transmitted messages and an applied key. Furthermore, it is shown that encryptions which perform equally well for n = 1 may perform differently when n > 1.

Work in voluntary welfare organizations : A sociological study of voluntary welfare organizations in Sweden
- 2004
-
Doktorsavhandling (övrigt vetenskapligt)abstract
- Since Sweden has one of the most comprehensive welfare states, the role of voluntary organizations active in the field of welfare is often neglected. The unique Swedish nonprofit sector is characterized by 1) the tradition of popular mass movements in which members are central and the real owners of the organization, 2) large membership and volunteering, but low employment levels, 3) dominance in the fields of culture and recreation, but the relative marginalization in welfare. This Ph.D. dissertation empirically studies work and the perception of work in voluntary welfare organizations (VWOs) in Sweden. I completed a series of 38 interviews of employees and volunteers in four VWOs: 1) a children’s rights organization; 2) a women’s center; 3) a volunteer bureau; and 4) a humanitarian organization. A quantitative survey of some 200 VWOs supplements the qualitative data. Looking at the internal work setting and interactions between workers one realizes that work in VWOs is influenced not only by the popular mass movements (folkrörelser), which are the foundation model of all Swedish voluntary organizations, but also by paradigms emerging out of the public and for-profit sectors: 1) the public paradigm permanently shapes voluntary welfare organizations through the action of paid workers who often have public sector work experience; and 2) work in voluntary organizations is partly integrated into the regular labor market, and interfaces emerge between volunteering and professional life (for-profit paradigm). The private sphere also interferes with volunteering. Finally, this sheds a new light on the claims of VWOs that they are autonomous, “free” entities, and their contribution to social integration and strengthening of social ties.
