An analysis of court decisions involving injuries to participants and spectators in youth sport activities

The purpose of this study was to review and analyze judicial decisions involving injuries to participants and spectators in youth sport activities. For this research, youth sport activities are those adult-organized sport programs that are conducted outside of the school setting. The number of court cases is limited but the decisions have been significant. The study demonstrates that no area of youth sport is immune from the threat of a lawsuit as administrators, coaches, officials, national, state and local organizations have all been involved in litigation. The number and frequency of cases appear to be increasing and there appears to be a trend to settle cases out of court. Recent decisions place a responsibility on those who direct youth sport activities to provide adequate supervision during practice and games and inspect and maintain the environment to insure safe conditions for participants and spectators. A new emphasis has been added for proper instruction and the duty to warn those involved in the youth sport program of inherent risks in the activity

Against the Tide. A Critical Review by Scientists of How Physics and Astronomy Get Done

Nobody should have a monopoly of the truth in this universe. The censorship and suppression of challenging ideas against the tide of mainstream research, the blacklisting of scientists, for instance, is neither the best way to do and filter science, nor to promote progress in the human knowledge. The removal of good and novel ideas from the scientific stage is very detrimental to the pursuit of the truth. There are instances in which a mere unqualified belief can occasionally be converted into a generally accepted scientific theory through the screening action of refereed literature and meetings planned by the scientific organizing committees and through the distribution of funds controlled by "club opinions". It leads to unitary paradigms and unitary thinking not necessarily associated to the unique truth. This is the topic of this book: to critically analyze the problems of the official (and sometimes illicit) mechanisms under which current science (physics and astronomy in particular) is being administered and filtered today, along with the onerous consequences these mechanisms have on all of us.\ud \ud The authors, all of them professional researchers, reveal a pessimistic view of the miseries of the actual system, while a glimmer of hope remains in the "leitmotiv" claim towards the freedom in doing research and attaining an acceptable level of ethics in science

Elections in digital times: a guide for electoral practitioners

Strengthening democracy and electoral processes in the era of social media and Artificial Intelligence Democracy requires free, periodic, transparent, and inclusive elections. Freedom of expression, freedom of the press, and the right to political participation are also critical to societies ruled by the respect of human rights. In today’s rapidly evolving digital environment, opportunities for communication between citizens, politicians and political parties are unprecedented –– with information related to elections flowing faster and easier than ever, coupled with expanded opportunities for its verification and correction by a growing number of stakeholders. However, with billions of human beings connected, and disinformation and misinformation circulating unhinged around the networks, democratic processes and access to reliable information are at risk. With an estimated 56.8% of the world’s population active on social media and an estimate of 4 billion eligible voters, the ubiquity of social networks and the impact of Artificial Intelligence can intentionally or unintentionally undermine electoral processes, thereby delegitimizing democracies worldwide. In this context, all actors involved in electoral processes have an essential role to play. Electoral management bodies, electoral practitioners, the media, voters, political parties, and civil society organizations must understand the scope and impact of social media and Artificial Intelligence in the electoral cycle. They also need to have access to the tools to identify who instigates and spreads disinformation and misinformation, and the tools and strategies to combat it. This handbook aims to be a toolbox that helps better understand the current scenario and share experiences of good practices in different electoral settings and equip electoral practitioners and other key actors from all over the world to ensure the credibility of the democratic system in times of profound transformations

Getting Beyond Intuition in the Probable Cause Inquiry

Courts are proudly resigned to the fact that the probable cause inquiry is “nontechnical.” In order to conduct a search or make an arrest, police need to satisfy the probable cause standard, which the Supreme Court has deemed “incapable of precise definition or quantification into percentages.” The flexibility of this elusive standard enables courts to defer to police officers’ reasonable judgments and expert intuitions in unique situations. However, police officers are increasingly using investigative techniques that replace their own observational skills with test results from some other source, such as drug sniffing dogs, facial recognition technology, and DNA matching. The reliability of such practices can and should be quantified, but the vagueness of the probable cause standard renders it impossible for judges to determine which error rates are inconsistent with probable cause. This Article confronts the intersection between quantifiable evidence and the relentlessly fuzzy probable cause standard. It proposes that the probable cause standard be assigned a numerical value as a minimum threshold, especially in cases where probable cause is based on mechanistic techniques that essentially replace a police officer’s own judgment. The Article begins by exploring how the police and courts currently apply the probable cause standard, including courts’ confrontations with probabilities. It then explains why certain evidence should require quantified error rates to establish probable cause and how to properly calculate these error rates. In the final section, the Article argues that assigning a minimum percentage to probable cause would add much-needed clarity to the law and protect against systemic abuses

Eye quietness and quiet eye in expert and novice golf performance: an electrooculographic analysis

Quiet eye (QE) is the final ocular fixation on the target of an action (e.g., the ball in golf putting). Camerabased eye-tracking studies have consistently found longer QE durations in experts than novices; however, mechanisms underlying QE are not known. To offer a new perspective we examined the feasibility of measuring the QE using electrooculography (EOG) and developed an index to assess ocular activity across time: eye quietness (EQ). Ten expert and ten novice golfers putted 60 balls to a 2.4 m distant hole. Horizontal EOG (2ms resolution) was recorded from two electrodes placed on the outer sides of the eyes. QE duration was measured using a EOG voltage threshold and comprised the sum of the pre-movement and post-movement initiation components. EQ was computed as the standard deviation of the EOG in 0.5 s bins from –4 to +2 s, relative to backswing initiation: lower values indicate less movement of the eyes, hence greater quietness. Finally, we measured club-ball address and swing durations. T-tests showed that total QE did not differ between groups (p = .31); however, experts had marginally shorter pre-movement QE (p = .08) and longer post-movement QE (p < .001) than novices. A group × time ANOVA revealed that experts had less EQ before backswing initiation and greater EQ after backswing initiation (p = .002). QE durations were inversely correlated with EQ from –1.5 to 1 s (rs = –.48 - –.90, ps = .03 - .001). Experts had longer swing durations than novices (p = .01) and, importantly, swing durations correlated positively with post-movement QE (r = .52, p = .02) and negatively with EQ from 0.5 to 1s (r = –.63, p = .003). This study demonstrates the feasibility of measuring ocular activity using EOG and validates EQ as an index of ocular activity. Its findings challenge the dominant perspective on QE and provide new evidence that expert-novice differences in ocular activity may reflect differences in the kinematics of how experts and novices execute skills

Fair Play: Notes on the Algorithmic Soccer Referee

The soccer referee stands in for a judge. Soccer’s Video Assistant Referee (VAR) system stands in for algorithms that augment human deciders. Fair play stands in for justice. They are combined and set in a polycentric system of governance, with implications for designing, administering, and assessing human-machine combinations
