We used isozyme markers to obtain an estimate of multiple paternity (mating of females with multiple males) in the unisexual, haploid leafy liverwort Porella platyphylloidea. From a sample of 119 plants, 15 (12.6%) were non-sex-expressing, 16 (13.4%) were females without sporophytes, 38 (31.9%) were males, and 50 (42.0%) were females bearing sporophytes. Thus, 87.4% of all plants expressed sex, an
In The Act of Documenting (2016), Winston, Vanstone and Chi connect production studies with reception studies in docmedia. This work signals how the act of documenting, a performative practice within the media industries, is intrinsically connected with the act of watching, a performative practice within cultures of viewing. There are challenges in conducting documentary audience research, in part
Research on Nordic Noir inspired screen tourism addresses cross sector collaboration of television, publishing, tourism and leisure and the material places of screen tourism. We add to this research by specifically addressing mobility (e.g. movement or transportation) and motility (e.g. differential resources for mobility) within media, mobility and screen studies. In this chapter we explore how a
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
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
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
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
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
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
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
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
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
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
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
