Better Off by Risk Adjustment? Socioeconomic Disparities in Care Utilization in Sweden Following a Payment Reform

Reducing socioeconomic health inequalities is a key goal of most health systems. When care providers are paid prospectively, e.g., by a fixed sum per patient, existing inequalities may be sustained by the incentives to undertreat relatively unhealthy patients. To counter these incentives, prospective payments are often risk-adjusted based on observable patient characteristics. Despite that risk ad

A Model of Social Duties

We develop a formal model of social duties. Duties to respect entitlements (duties of justice) differ from duties to promote well-being (duties of charity). A situation- specific version of our model takes entitlements as primitives. A fully portable ver- sion derives entitlements from situational characteristics. Utility functions obtain kinks where duties of justice and charity are exactly satis

Secure Cloud Storage with Joint Deduplication and Erasure Protection

This work proposes a novel design for secure cloud storage systems using a third party to meet three seemingly opposing demands: reduce storage requirements on the cloud, protect against erasures (data loss), and maintain confidentiality of the data. More specifically, we achieve storage cost reductions using data deduplication without requiring system users to trust that the cloud operates honest

Bargaining for Trade: When Exporting Becomes Detrimental for Female Wages

In this paper we study the link between globalization of firms and gender inequality. Specifically, we examine how the need for interpersonal contacts in trade and gender-specific differences in negotiations are related to the gender wage gap. Our key finding is that export of goods that are intensive in interpersonal contacts widens the gender wage gap. The effect is robust across various specifi

Towards a Learning Philosophy Based on Experience in Entrepreneurship Education

If experience is the guiding light in entrepreneurship education, then where is the philosophy of experience? This article illuminates the philosophical foundations of entrepreneurship education by discussing learning through experience. We introduce a diagram that addresses primary and secondary experiences and their interplay as well as a model that further reveals how educative entrepreneurial

Preferences for Colours on Buildings

The Swedish psychologist, Lars Sivik, was probably the first to carry out a scientific study of the perception of building exteriors in different colours. He applied more than 60 colours to two types of buildings - ‘high-rise house’ and ‘low-rise house’ - by means of a photographic simulation technique. Science is much better equipped to tackle the complicated questions of colour preference in the

Own Motivation, Peer Motivation, and Educational Success

I study how motivation shapes own and peers’ educational success. Using data from Project STAR, I find that academic motivation in early elementary school, as measured by a standardized psychological test, predicts contemporaneous and future test scores, high school GPA, and college-test taking over and above cognitive skills. Exploiting random assignment of students to classes, I find that exposu

Tuition Fees and Educational Attainment

Following a landmark ruling by the Constitutional Court in 2005, more than half of Germany’s universities started charging tuition fees, which also applied to incumbent students. We exploit this unusual lack of grandfathering together with register data covering the universe of students to show that tuition fees increased degree completion among incumbent students. Investigating mechanisms, we do

Climate and soil properties drive soil organic and inorganic carbon patterns across a latitudinal gradient in southwestern China

PurposeDrylands account for 47.2% of land area and contain 15.5% of global carbon (C). However, the variation in organic and inorganic C stocks across latitudinal gradients in arid and semiarid shrubland ecosystems remains understudied, and we lack in-depth understanding of the main drivers of C variation at this spatial scale.MethodsHere, we sampled soils from 95 sites across a latitudinal gradie

Testosterone deficiency and metabolic disturbances in men who fathered a child by use of donated spermatozoa

Dose-response association between level of impairment of semen quality and risk of morbidity or premature death has been reported. Therefore, it can be presumed that men utilizing donated spermatozoa, i.e. patients with non-obstructive azoospermia, are at highest risk for adverse health outcomes. To evaluate the risks of prescription of medications for common metabolic disturbances and testosteron

Barriers to Learning in Contracting : An Empirical Exploration of Contracting Capabilities in Buyer-Supplier Relationships

Under what conditions do firms in buyer-supplier relationships learn to contract? Contract design capabilities are typically understood as a function of the contractual problems faced by firms. However, a firms’ learning to contract is also likely affected by the organizational and institutional conditions in which contracts are entered. Based on five inductive case studies of buyer-supplier relat

Malmö POTS symptom score : Assessing symptom burden in postural orthostatic tachycardia syndrome

BACKGROUND: Postural orthostatic tachycardia syndrome (POTS) is a common cardiovascular autonomic disorder characterized by excessive heart rate (HR) increase on standing and symptoms of orthostatic intolerance, posing significant limitations on functional capacity. No objective tool exists to classify symptom burden in POTS.METHODS: We conducted a case-control study in 62 POTS patients and 50 hea

Sex differences between early- and late-onset Alzheimer’s disease.

Objectives: To examine potential sex differences in longitudinal cognitive and activities of daily living (ADL) performance and life expectancy between early- and late-onset Alzheimer’s disease (AD). Methods: The Swedish Alzheimer Treatment Study is a prospective, observational, multicentre study that was used in a routine clinical setting including 1,017 patients diagnosed with mild-to-moderate A

Accurate experimental lifetimes of excited levels in sodiumlike sulfur, S VI

The lifetimes of the terms 3p2P, 3d2D, 4s2S, 4p2P, 4d2D, 4f2F, 5g2G, 6g2G, 6h2H, 7h2H, 7i2I and 8k2K in sodiumlike sulfur, S VI, have been determined using the beam-foil excitation technique. Most of the decay curves were analyzed by means of the ANDC method which corrects for cascading in a very detailed way. Accurate results were thereby obtained which show that an excellent agreement exists bet

Structure and line strengths in extreme jK coupling: an experimental and theoretical study in Ni ii

The spectrum emitted from a nickel hollow cathode has been recorded with a Fourier transform spectrometer. Two dense groups of lines just above 18 000 Å have been identified as the transitions 3d8 (3F)5f-3d8 (3F)6g and 3d8 (3F)5g-3d8 (3F)6h in Ni II. The level structure of the configurations involved in these transitions has been studied by fitting the Slater parameters of the energy matrices to t

Exploring Direct Conversion of Human Glia into Therapeutic Neurons

Direct neuronal reprogramming of a somatic cell into therapeutic neurons, without a transient pluripotent state, provides new promise for the large number of individuals afflicted by neurodegenerative diseases or brain injury. This approach could be potentially applied directly in the brain by targeting resident cells as a source of new neurons. Direct neuronal conversion of resident glial cells i
