We re-examine Peres' statement “opposite momenta lead to opposite directions”. It will be shown that Peres' statement is only valid in the large distance or large time limit. In the short distance or short time limit an additional deviation from perfect alignment occurs due to the uncertainty of the location of the source. This error contribution plays a major role in Popper's orginal experimental proposal. Peres' statement applies rather to the phenomenon of optical imaging, which was regarded by him as (...) a verification of his statement. This is because this experiment can in a certain sense be seen as occurring in the large distance limit. We will also reconsider both experiments from the viewpoint of Bohmian mechanics. In Bohmian mechanics particles with perfectly opposite momenta will move in opposite directions. In addition it will prove particularly useful to use Bohmian mechanics because the Bohmian trajectories coincide with the conceptual trajectories drawn by Pittman et al. In this way Bohmian mechanics provides a theoretical basis for these conceptual trajectories. (shrink)

The impact of COVID-19 on chronic pain in non-infected vulnerable South American subjects is unknown. Healthcare workers are at increased risk for CP. During the pandemic, many HCWs with CP kept working. Knowing how cognition is affected by CP in these subjects is an important subject for work safety. The attention domain has a pivotal role in cognition. Previously, the Continuous Visual Attention Test was applied to detect specific attention deficits in fibromyalgia patients. The present investigation described CP prevalence in (...) non-infected Brazilian HCWs during the pandemic and assessed HCWs’ attentional performance with the aid of the CVAT. This study was carried out at a reference University Hospital in Rio de Janeiro, Brazil. HCWs of both sexes, aged 20 or older, were interviewed from August to December 2020. A 90-second version of the CVAT was performed. The average reaction time to correct responses and the respective intraindividual reaction time variability for correct responses to target was determined. Omission and commission errors were also calculated. Then, for each participant we calculated the Z-scores of the CVAT variables based on the distribution of CVAT performance of 211 healthy subjects. HCWs with Z-scores > 1.64 were classified as significantly impaired. From the 154 selected HCWs, 72 reported CP during the pandemic. Post hoc ANCOVAs showed that the average correct VRT was significantly higher in the CP group than in the non-CP group. The percentage of participants with impaired VRT performance was 30% in the CP group and 16% in the non-CP group. The difference between these two propositions reached significance. As VRT is associated with the sustained-attention subdomain, our data suggest that this subdomain is disrupted in the CP group. (shrink)

Theorists, historians, and artists address the precarious futurity of the notion of the future. Not long ago, a melancholic left and a manic neoliberalism seemed to arrive at an awkward consensus: the foreclosure of futurity. Whereas the former mourned the failure of its utopian project, the latter celebrated the triumph of a global marketplace. The radical hope of realizing a singularly different, more equitable future displaced by a belief that the future had already come to pass, limiting post-historical society to (...) an uneventful life of endless accumulation. Today, amidst an abundance of neofuturisms, posthumanisms, futurologies, speculative philosophies and accelerationist scenarios, there is as well an expanding awareness of a looming planetary catastrophe driven by the extractionist logic of capitalism. Despite this return to the future, the temporal horizon of our present moment is perhaps more aptly characterized by the “shrinking future” of just-in-time production, risk management, high-frequency trading, and the futures market. In Futurity Report, theorists, historians, and artists address the precarious futurity of the notion of the future itself.

After having defined the KARO logic for specifying intelligent agents in earlier work we now turn to the question how to realise agents specified in the KARO framework. To this end we look at agent programming languages that we have defined, and investigate how programs in these languages can be linked to the KARO logic.

The past 50 years have seen an accumulation of evidence suggesting that associative learning depends on high-level cognitive processes that give rise to propositional knowledge. Yet, many learning theorists maintain a belief in a learning mechanism in which links between mental representations are formed automatically. We characterize and highlight the differences between the propositional and link approaches, and review the relevant empirical evidence. We conclude that learning is the consequence of propositional reasoning processes that cooperate with the unconscious processes involved (...) in memory retrieval and perception. We argue that this new conceptual framework allows many of the important recent advances in associative learning research to be retained, but recast in a model that provides a firmer foundation for both immediate application and future research.

When the COVID-19 surge hit New York City hospitals, the Division of Medical Ethics at Weill Cornell Medical College, and our affiliated ethics consultation services, faced waves of ethical issues sweeping forward with intensity and urgency. In this article, we describe our experience over an eight-week period (16 March through 10 May 2020), and describe three types of services: clinical ethics consultation (CEC); service practice communications/interventions (SPCI); and organizational ethics advisement (OEA). We tell this narrative through the prism of time, (...) describing the evolution of ethical issues and trends as the pandemic unfolded. We delineate three phases: anticipation and preparation, crisis management, and reflection and adjustment. The first phase focused predominantly on ways to address impending resource shortages and to plan for remote ethics consultation, and CECs focused on code status discussions with surrogates. The second phase was characterized by the dramatic convergence of a rapid increase in the number of critically ill patients, a growing scarcity of resources, and the reassignment/ redeployment of staff outside their specialty areas. The third phase was characterized by the recognition that while the worst of the crisis was waning, its medium- and long-term consequences continued to pose immense challenges. We note that there were times during the crisis that serving in the role of clinical ethics consultant created a sense of dis-ease as novel as the coronavirus itself. In retrospect we learned that our activities far exceeded the familiar terrain of clinical ethics consultation and extended into other spheres of organizational life in novel ways that were unanticipated before this pandemic. To that end, we defined and categorized a middle level of ethics consultation, which we have termed service practice communication intervention (SPCI). This is an underappreciated dimension of the work that ethics consult services are capable of in times of crisis. We believe that the pandemic has revealed the many enduring ways that ethics consultation services can more robustly contribute to the ethical life of their institutions moving forward. (shrink)

We develop a framework for assessing security market quality, relating five elements of market design to three metrics of market integrity and two metrics of market efficiency. We empirically implement this integrity–efficiency MQ framework by testing a hypothesis that trade-based ramping manipulation at the close raises execution costs on 24 security markets worldwide. Estimating a simultaneous equations model of ramping incidence, spreads, and the probability of deploying real-time surveillance, we show that quoted bid-ask spreads are positively related to the incidence (...) of MTC across seven liquidity deciles. The magnitude is economically significant; improving market integrity by cutting MTC in half reduces spreads 6–11 %. Allowing direct market access in conjunction with RTS, conducting auctions at the close, and developing regulations that require surveillance, all reduce MTC and thereby lower spreads, assuring better market integrity and enhancing market efficiency. Introducing circuit breakers or prohibiting shorts poses integrity–efficiency tradeoffs. (shrink)

Advanced practice nursing is an expanding field within many healthcare environments around the world. The scope and particular focus of an advanced practice nurse’s role is highly variable and thus the ethical challenges they face are equally diverse. Yet, the dominant existing ethics pedagogies used in the nursing context have been described as not fit-for-purpose. Existing pedagogies do not adequately prepare APN candidates to meet the ethical challenges they will encounter in practice. Applying an arts-based pedagogy in ethics education for (...) advanced practice nurses has the capacity to provide effective ethics learning. This article reports on the value of a multidisciplinary pedagogy used in a graduate course in nursing leadership, law and ethics for advanced practice at an Australian university. Written in a multidisciplinary mode that allies with the pedagogy it presents, it addresses the key pedagogical challenges and opportunities of teaching ethics through an innovative arts-based pedagogy centred upon the changing depictions of the human person in works of art housed in a major state-funded art gallery.

The aim of this article is to take relational ethics concepts and apply them to the context of application to research ethics committees for approval to carry out research. The process of a multinational qualitative research application is described. The article suggests that a relational ethics approach can address two issues: how qualitative proposals are interpreted by research ethics committees and how this safeguards potentially vulnerable respondents. In relational terms, the governance of a research project may be enhanced by shared (...) ownership and willingness to engage in mutual dialogue. This challenges both researchers and research ethics committees to reframe their understanding of roles and functions in the assessment of research protocols, particularly those of a qualitative nature and those that address end-of-life issues.
