Wealth, families and death: socio-legal perspectives on wills and inheritance: introduction

Inheritance as both a concept and a practice is of deep significance within all societies and jurisdictions. Located at the intersection between economics, family relations and the end of life, it offers a unique perspective on a variety of contemporary socio-legal debates. Yet the socio-legal phenomenon of inheritance has attracted relatively little scholastic attention. This special issue, which brings together eight papers coming from six different countries (and eight different jurisdictions): Belgium, England and Wales, Israel, Spain (Catalonia and the Basque Country), Switzerland and the USA, demonstrates the breadth of inheritance as a field of study in a number of ways and at the same time opens up important new lines of enquiry. This international breadth serves to foreground the significance of both national and regional political culture on inheritance law. Most significant in this respect is the fact that the authors are evenly split between those commentating on civil legal systems and those on common-law systems; for traditionally the two systems have adopted highly distinct responses to the principles of testamentary freedom and forced heirship. All the articles in this collection provide insight into this fundamental distinction but at the same time demonstrate its limits in practice

Flexible learning in a partnership context for beginning teachers

A preliminary inventory was carried out for a sample of male and female student teachers who had email accounts. Preliminary inventory data revealed that the mean number of times per week that males used email was significantly higher than the mean number for female students. This inventory data indicated that characteristics such as gender affect Internet educational technology utilization, and this factor was addressed within the experimental design for the main study. In the main study, student teachers were assigned to four treatment groups for learning lesson‐planning skills. The first two groups received a traditional university lecture followed by a seminar. For group I, the seminar was provided at university. For group 2, the seminar was provided as part of the student's school‐based experiences. Groups 3 and 4 received identical tuition to groups 1 and 2 respectively, except that tuition was provided on a flexible learning basis, being delivered electronically via the Internet with tutorial support from the university lecturer by way of asynchronous email. It was found that student achievement was significantly higher when tuition was provided as part of the student's school‐based experiences, and also that achievement was significantly higher when tuition was provided on a flexible learning basis involving computer‐mediated communications. A separate AN OVA was carried out for the entire sample of the four treatment groups in order to address the factor of student gender, which was controlled in the experiment. However, there were no significant differences in achievement associated with student gender. This surprising finding suggests that although male. students may make greater usage of information technology, when required to do so, female students perform on a par with their male counterparts

Experimental Values of the Surface Tension of Supercooled Water

The results of surface-tension measurements for supercooled water are presented. A total of 702 individual measurements of surface tension of triple-distilled water were made in the temperature range, 27 to -22.2 C, with 404 of these measurements at temperatures below 0 C. The increase in magnitude of surface tension with decreasing temperature, as indicated by measurements above 0 C, continues to -22.2 C. The inflection point in the surface-tension - temperature relation in the vicinity of 0 C, as indicated by the International Critical Table values for temperatures down to -8 C, is substantiated by the measurements in the temperature range, 0 to -22.2 C. The surface tension increases at approximately a linear rate from a value of 76.96+/-0.06 dynes per centimeter at -8 C to 79.67+/-0.06 dynes per centimeter at -22.2 C

Soft hairy warped black hole entropy

We reconsider warped black hole solutions in topologically massive gravity and find novel boundary conditions that allow for soft hairy excitations on the horizon. To compute the associated symmetry algebra we develop a general framework to compute asymptotic symmetries in any Chern-Simons-like theory of gravity. We use this to show that the near horizon symmetry algebra consists of two u(1) current algebras and recover the surprisingly simple entropy formula $S=2\pi (J_0^+ + J_0^-)$, where $J_0^\pm$ are zero mode charges of the current algebras. This provides the first example of a locally non-maximally symmetric configuration exhibiting this entropy law and thus non-trivial evidence for its universality.Comment: 24pp, v2: added appendix C and minor edit

Matching Code and Law: Achieving Algorithmic Fairness with Optimal Transport

Increasingly, discrimination by algorithms is perceived as a societal and legal problem. As a response, a number of criteria for implementing algorithmic fairness in machine learning have been developed in the literature. This paper proposes the Continuous Fairness Algorithm (CFA$\theta$) which enables a continuous interpolation between different fairness definitions. More specifically, we make three main contributions to the existing literature. First, our approach allows the decision maker to continuously vary between specific concepts of individual and group fairness. As a consequence, the algorithm enables the decision maker to adopt intermediate ``worldviews'' on the degree of discrimination encoded in algorithmic processes, adding nuance to the extreme cases of ``we're all equal'' (WAE) and ``what you see is what you get'' (WYSIWYG) proposed so far in the literature. Second, we use optimal transport theory, and specifically the concept of the barycenter, to maximize decision maker utility under the chosen fairness constraints. Third, the algorithm is able to handle cases of intersectionality, i.e., of multi-dimensional discrimination of certain groups on grounds of several criteria. We discuss three main examples (credit applications; college admissions; insurance contracts) and map out the legal and policy implications of our approach. The explicit formalization of the trade-off between individual and group fairness allows this post-processing approach to be tailored to different situational contexts in which one or the other fairness criterion may take precedence. Finally, we evaluate our model experimentally.Comment: Vastly extended new version, now including computational experiment

Dissemination of evidence-based standards of care.

Standards of care pertain to crafting and implementing patient-centered treatment interventions. Standards of care must take into consideration the patient's gender, ethnicity, medical and dental history, insurance coverage (or socioeconomic level, if a private patient), and the timeliness of the targeted scientific evidence. This resolves into a process by which clinical decision-making about the optimal patient-centered treatment relies on the best available research evidence, and all other necessary inputs and factors to provide the best possible treatment. Standards of care must be evidence-based, and not merely based on the evidence - the dichotomy being critical in contemporary health services research and practice. Evidence-based standards of care must rest on the best available evidence that emerges from a concerted hypothesis-driven process of research synthesis and meta-analysis. Health information technology needs to become an every-day reality in health services research and practice to ensure evidence-based standards of care. Current trends indicate that user-friendly methodologies, for the dissemination of evidence-based standards of care, must be developed, tested and distributed. They should include approaches for the quantification and analysis of the textual content of systematic reviews and of their summaries in the form of critical reviews and lay-language summaries

Caging Mechanism for a drag-free satellite position sensor

A disturbance compensation system for satellites based on the drag-free concept was mechanized and flown, using a spherical proof mass and a cam-guided caging mechanism. The caging mechanism controls the location of the proof mass for testing and constrains it during launch. Design requirements, design details, and hardware are described
