Caring Leader Identity Between Power and Powerlessness

This paper investigates what happens when managers’ identity is centred on caring, an underappreciated aspect of leadership. Drawing on a case study of managers in elderly care, we distil an ideal-typical caring leader identity as well as contextualised interpretations that suggest both problematic and constructive aspects. The caring leader identity implies a self-understanding as being highly pr

Infective endocarditis caused by HACEK group bacteria—a registry-based comparative study

Infective endocarditis (IE) caused by bacteria within Haemophilus (excluding Haemophilus influenzae), Aggregatibacter, Cardiobacterium, Eikenella and Kingella (HACEK) is rare. This study aimed to describe clinical features of IE caused by HACEK genera in comparison with IE due to other pathogens. Cases of IE due to HACEK were identified through the Swedish Registry of Infective Endocarditis (SRIE)

Simultaneous modeling of Alzheimer's disease progression via multiple cognitive scales

Analyzing the progression of Alzheimer's disease (AD) is challenging due to lacking sensitivity in currently available measures. AD stages are typically defined based on cognitive cut-offs, but this results in heterogeneous patient groups. More accurate modeling of the continuous progression of the disease would enable more accurate patient prognosis. To address these issues, we propose a new mult

Paths academic scientists take to entrepreneurship : Disaggregating direct and indirect influences

Based on information from a large sample of German researchers and using business ownership and nascent entrepreneurship as alternative indicators of academic entrepreneurship, we use mediation analysis to analyze the direct effects of researchers' entrepreneurship attitudes, age, gender, and citizenship as well as the related indirect influences. Industrial cooperation, industry consulting, and p

Interpolatory-Based Data-Driven Pulsed Fluidic Actuator Control Design and Experimental Validation

Pulsed fluidic actuators (PFAs) play a central role in the fluid flow experimental control strategy to achieve better performances of aeronautic devices. In this brief, we demonstrate, through an experimental test bench, how the interpolatory-based Loewner data-driven control (L-DDC) framework is an appropriate tool for accurately controlling the outflow velocity of this family of actuators. L-DDC

37 forskare och debattörer: AP-fonderna måste divestera

Hälften av alla pengar på börsen är våra pensionspengar. Det är fullständigt oacceptabelt att AP-fonderna placerar dem i fossilbranchen, skriver 37 forskare och debattörer.Half of all our pension money are invested in stocks. These funds support fossil fuel companies, which is totally inacceptable. 37 researcerhs and debaters demand divestification of these stocks.

Capacity Bounds and Degrees of Freedom for MIMO Antennas

The optimal spectral efficiency and number of independent channels for MIMO antennas in isotropic multipath channels are investigated when bandwidth requirements are placed on the antenna. By posing the problem as a convex optimization problem restricted by the port Q-factor a semi-analytical expression is formed for its solution. The antennas are simulated by method of moments and the solution is

Contrasting use of space by two migratory Afro-Palearctic warblers on their African non-breeding grounds

In migratory birds, constraints due to breeding are relaxed during the non-breeding season and thus, social behaviours and spatial associations are potentially more directly coupled to food resources and habitats. Use of space and territorial behaviour has rarely been studied in Afro-Palearctic migrants. Variation in strategies could exist among species within the same habitat because of differenc

Health status and academic performance in offspring of central nervous system tumor survivors

Background: An increasing number of patients with central nervous system (CNS) tumor could survive to reproductive age and successfully have children, especially patients diagnosed at a younger age. However, it is largely unknown whether the history of CNS tumor and its treatments might affect their children. We aimed to explore the health status and school performance in offspring of survivors wi

Lane-deviation penalty formulation and analysis for autonomous vehicle avoidance maneuvers

Autonomous vehicles hold promise for increased vehicle and traffic safety, and there are several developments in the field where one example is an avoidance maneuver. There it is dangerous for the vehicle to be in the opposing lane, but it is safe to drive in the original lane again after the obstacle. To capture this basic observation, a lane-deviation penalty (LDP) objective function is devised.

Spatially Coupled Generalized LDPC Codes : Asymptotic Analysis and Finite Length Scaling

Generalized low-density parity-check (GLDPC) codes are a class of LDPC codes in which the standard single parity check (SPC) constraints are replaced by constraints defined by a linear block code. These stronger constraints typically result in improved error floor performance, due to better minimum distance and trapping set properties, at a cost of some increased decoding complexity. In this paper

Managing extended supply chains

We address how to manage extended supply chains that lie beyond the first-tier suppliers. The first-tier suppliers have their suppliers who provide them with goods or services. While lower-tier suppliers are often not an explicit concern of the focal firm, the firm's performance not only depends on the performance of its first-tier suppliers, but also on the performance of their suppliers and beyo

Pattern, timing and predictors of recurrence after surgical resection of chromophobe renal cell carcinoma

Purpose: Currently there are no specific guidelines for the post-operative follow-up of chromophobe renal cell carcinoma (chRCC). We aimed to evaluate the pattern, location and timing of recurrence after surgery for non-metastatic chRCC and establish predictors of recurrence and cancer-specific death. Methods: Retrospective analysis of consecutive surgically treated non-metastatic chRCC cases from

Educational Design Framework for a Web-Based Interface to Visualise Authentic Cosmological “Big Data” in High School

The changing landscape of science and science education has provided an impetus to re-imagine how science can be taught in schools. The dawn of the Big Data era, especially in astronomy, and the notion of “Science as Practice” are some of the developments driving this need for a re-imagination of science education. This current work contributes to this agenda by exploring the features an education

Postprandial glycaemic dips predict appetite and energy intake in healthy individuals

Understanding how to modulate appetite in humans is key to developing successful weight loss interventions. Here, we showed that postprandial glucose dips 2–3 h after a meal are a better predictor of postprandial self-reported hunger and subsequent energy intake than peak glucose at 0–2 h and glucose incremental area under the blood glucose curve at 0–2 h. We explore the links among postprandial g

Simulation of thermal and mechanical performance of laser cladded disc brake rotors

Disc brakes wear during braking events and release airborne particulates. These particle emissions are currently one of the highest contributors to non-exhaust particle emissions and introduce health hazards as well as environmental contamination. To reduce this problem, wear and corrosion-resistant disc coatings have been implemented on grey cast iron brake disc rotors by using various deposition

Using Light to Probe Surface Electrochemical Processes

Kemiska reaktioner drivna av en ström eller som producerar en ström heter elektrokemiska reaktioner och finns överallt omkring oss, ta bara till exempel ett batteri, här produceras en ström som kan driva till exempel din mobiltelefon. Förståelsen för dessa kemiska reaktioner och hur de påverkar den yta där reaktionerna sker är därför viktig. Det är också viktigt att förstå hur olika strukturer reaThis thesis shows how various light-based in situ techniques can be used to follow different surface electrochemical processes such as electrochemical deposition into Nanoporous Anodic Aluminium Oxide (NP-AAO) templates and the surface structure of electrodes. Techniques based on both x-rays and visible light were used to follow surface structures and compositions, in situ. The samples were alsoin

Health Care Utilization and Associated Economic Burden of Postoperative Surgical Site Infection after Spinal Surgery with Follow-Up of 24 Months

Background Surgical site infection (SSI) may lead to vertebral osteomyelitis, diskitis, paraspinal musculoskeletal infection, and abscess, and remains a significant concern in postoperative management of spinal surgery. SSI is associated with greater postoperative morbidity and increased health care payments. Methods We conducted a retrospective analysis using MarketScan to identify health care ut

Cost-Effectiveness of Device-Aided Therapies in Parkinson's Disease : A Structured Review

Background: Despite optimal dopaminergic treatment most patients in moderate to advanced stages of Parkinson's disease (PD) experience progressively increasing disabilities, necessitating a shift from oral medication to device-aided therapies, including deep brain stimulation (DBS), intrajejunal levodopa-carbidopa infusion (IJLI), and continuous subcutaneous apomorphine infusion (CSAI). However, t
