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

Risk factors for recurrence and complications in acute uncomplicated diverticulitis : A retrospective cohort study

Introduction: Antibiotics for acute uncomplicated diverticulitis (AUD) have been questioned in several studies. Thus, it is of value to identify risk factors for recurrence and complications to identify the best strategy for treatment. The aim was to investigate risk factors for recurrence and complications within at least 1 year after hospitalization for AUD. Methods: This is a retrospective stud

Det allmänna rättsmedvetandet och några svenska förarbeten på straffrättens område 2008–2018

This article focuses on what is often termed the general (or public) sense of justice, GSJ for short. It illustrates the influence that the GSJ has had on various preparatory works in Swedish criminal law during a recent decade. It is often claimed that the GSJ is used as an argument in political discourse and decision making in the area of criminal law, especially to motivate criminalisation and

Numerical study of heat transfer, flow fields, turbulent length scales, and anisotropy in corrugated heat exchanger channels

In this study, we report on large eddy simulation (LES) of convectively dominated heat transfer in a corrugated heat exchanger channel using the computational fluid dynamics toolbox, OpenFOAM. A chevron pattern domain with 63 contact points is used to represent the conditions in a real plate heat exchanger (PHE). The unsteady nature of the flow is elucidated using visualization techniques based on
