TL;DR: In this article , Gill and Lambare pointed out that the violation of inequalities and apparent violation of no-signaling in Bell tests may be explained in a locally causal way, which does not allow for doubt regarding the existence of objective external physical reality and causal locality in nature.
Abstract: In [1, 2], Gill and Lambare (GL) criticize our uncontroversial paper [3] published in Frontiers in Physics. They claim that their “findings” apply to our preceding papers [4–6] and even to those by other authors. They seem to suggest that the content and conclusions of [3] are invalid because they are based on a false mathematical claim and reasoning. This is unfounded, unfair, and misleading. A longer reply to their criticism may be found in [7]. In [3], we correctly demonstrate that the violation of inequalities and apparent violation of no-signaling in Bell tests may be explained in a locally causal way. Therefore, the violation of inequalities does not allow for doubt regarding the existence of objective external physical reality and causal locality in nature. The joint probability (JP) distribution of four random variables describes a random experiment in which four outcomes are outputted in each trial. Only then can CHSH be derived and obeyed by all finite samples. In our probabilistic framework, such JP does not exist, and four experiments are described by random variables implemented on four disjoint dedicated probability spaces. GL construct a counterfactual probabilistic model in which random variables representing outcomes of four experiments performed using incompatible experimental settings are jointly distributed. Thus, CHSH inequalities trivially hold for all finite samples generated by their model. Their model defines a probabilistic coupling for our model describing raw data from Bell tests [7]. The existence of this coupling does not invalidate the derivation of the contextual probabilistic model describing the final data from Bell tests. Only these final data are used to test Bell inequalities. Inequalities cannot be derived because our model violates statistical independence [4,8,10]. OPEN ACCESS

TL;DR: This paper analyzed how adverse working conditions shape frontline workers' behavioral and cognitive coping mechanisms and found that they feel abandoned, vulnerable, and left to deal with the risks of the pandemic by themselves, and tend to cognitively disconnect from their work and prioritize their own job survival.
Abstract: This study analyzes how adverse working conditions shape frontline workers' behavioral and cognitive coping mechanisms. It builds on the idea of frontline work as a precarious profession and explores how workers deal with associated challenges. Specifically, evidence is provided for factors associated with alienative commitment among frontline workers. We do so against the background of the 2020–2021 Mexican and Brazilian pandemic response by health workers, social workers, and police officers. Findings from our qualitative analysis show that they feel abandoned, vulnerable, and left to deal with the risks of the pandemic by themselves. In response, they tend to cognitively disconnect from their work and prioritize their own job survival. We contribute to the literature by showing how institutional factors over which street-level bureaucrats have little control, such as resource scarcity, lack of job security and managerial support, and low trust by citizen-clients, are fertile conditions for these coping patterns.

TL;DR: In this paper , the authors argue that the evaluation, design, and implementation of AI health monitoring should be guided by a relational conception of autonomy, which addresses both people's capacity to exercise their agency and broader issues of power asymmetry and social justice.
Abstract: Abstract Respect for patient autonomy and data privacy is generally accepted as one of the foundational Western bioethical values. Nonetheless, as our society embraces expanding forms of personal and health monitoring, particularly in the context of an aging population and the increasing prevalence of chronic diseases, questions abound how artificial intelligence (AI) may change the way we define or understand what it means to live a free and healthy life. Drawing on different use cases of AI health monitoring, this book explores the socio-relational contexts that frame the promotion of AI health monitoring, as well as the potential consequences of such monitoring for people’s autonomy. It argues that the evaluation, design, and implementation of AI health monitoring should be guided by a relational conception of autonomy, which addresses both people’s capacity to exercise their agency and broader issues of power asymmetry and social justice. It explores how interpersonal and socio-systemic conditions shape the cultural meanings of personal responsibility, healthy living/aging, trust, and caregiving. These norms in turn structure the ethical space within which expectations regarding predictive analytics, risk tolerance, privacy, self-care, and trust relationships are expressed. Through an analysis of home health monitoring for older and disabled adults, direct-to-consumer health monitoring devices, and medication adherence monitoring, this book proposes ethical strategies at both the professional and systemic levels that can help preserve and promote people’s relational autonomy in the digital era.

TL;DR: In this article , the authors summarise the book's overarching arguments that leaving nobody behind requires that culture is permanently admitted into the working of the state and that substantive indigenous leadership and participation occur wherever state policy is made, implemented and evaluated.
Abstract: This chapter summarises the book’s overarching arguments that leaving nobody behind requires that culture is permanently admitted into the working of the state and that substantive indigenous leadership and participation occur wherever state policy is made, implemented and evaluated. Agency, not vulnerability, then guides what it means to say that indigenous people are not left behind. Indigenous presence in state policy processes complements indigenous peoples’ right to self-determination as independent political communities. The chapter concludes with additions to the indicators for each of the 17 goals to show how they may contribute to the detailed expression of self-determination that the book has presented and defended.

TL;DR: In this article , a philosophical short story fiction, the narrator goes to an upscale, "undiscovered artists" experience in New York City and while at the event she realizes there is a dead homeless person hanging from the ceiling in the corner.
Abstract: Is a dead homeless person social commentary? Is a dead homeless person art? In this philosophical short story fiction, the narrator goes to an upscale, “undiscovered artists” experience in New York City. While at the event she realizes there is a dead homeless person hanging from the ceiling in the corner. Nobody seems to mind, and she assumes people just haven’t noticed. As the show finishes, she realizes people do notice, are not offended and, in fact, simply consider the dead person is part of the artistic experience. The narrator questions the security guards who explain the homeless person died on the street and was moved into the gallery to wait until the police showed up. Dead homeless people are common enough that, even after this one is removed, another will be available shortly to take its place.

TL;DR: In this article , the authors present the state of the art of Serious Games and their usages in the educational environment, their assets in knowledge consolidation, and the necessary conditions to make the Serious Games an effective and useful tool for consolidating knowledge, accompanied by a conceptual model that will be concretized later.
Abstract: The learning of many children around the world has been challenged by the implementation of technology in each individual’s life. Nowadays, the amount of time spent on televisions, smartphones, and digital activities has become very high, a hindrance to the assimilation of knowledge in schools and the objective of this later as a whole. Nobody can deny that this phenomenon is a result of society’s evolution which cannot be stopped. In this regard, video games as well as social networks are of paramount importance to be implemented in teaching since they are currently part of the students’ daily lives. This contribution sheds light on the reason for the introduction of Serious Games (SG) in the educational system. It lists some nationally and internationally renowned surveys that have elucidated the causes of students’ failure and their gradual decline in academic performance. This document will also present the state of the art of Serious Games and their usages in the educational environment, their assets in knowledge consolidation. Some concrete examples of Serious Game software will be cited later. Finally, this work will describe the necessary conditions to make the Serious Games an effective and useful tool for consolidating knowledge, accompanied by a conceptual model that will be concretized later.

TL;DR: In this paper , the authors introduced a new health monitoring scheme called Covid Patients Health Analyzer (CPHA), in which this methodology is associated with the help of trending technology called Internet of Things (IoT).
Abstract: In the year of 2019, a major destruction was raised to all over the Country called as Coronavirus, which is also termed as Covid-19. This is one of the serious threat and many people lost their lives due to the affection of Coronavirus disease. Due to the spread ratio and nature, nobody is interested to properly monitor the patients who are all affected with this disease. So, that a new technology is required to monitor the health conditions of patients and instantly reporting the details to the respective person and guardian as well. As technology advances, doctors are constantly on the lookout for new automated gadgets that might make it simpler to detect abnormalities in the human body. The Internet of Things makes it possible to create cutting-edge, transparent healthcare support structures. This paper introduced a new health monitoring scheme called Covid Patients Health Analyzer (CPHA), in which this methodology is associated with the help of trending technology called Internet of Things (IoT). This system introduces an Internet of Things assisted patient health surveillance technology, which aids medical professionals in remotely measuring the blood concentration, pulse rate, respiration level and temperature of the respective patient. Both the person's pulse rate and blood oxygen sufficiency levels are read using an intelligent sensor called MAX3100, whereas the individual's temperature is scanned with a powerful sensor called DS18B20. Using a humidity identification sensor, one may determine the relative humidity of a given space. All required information will be encoded and decoded by the ESP32 module before being processed. The patients Fingers are hooked up to sensors as well as readings are shown on a respective computer or smartphone. After putting the suggested system through its paces, the working is clearly tested and it delivers the desired results in good manner. By monitoring the process remotely, medical personnel no longer need to worry about contracting the coronavirus when examining the conditions of multiple patients at once using this suggested technology.

TL;DR: In this article , a questionnaire was applied to teachers of basic and secondary education between the 3rd and the 31st of January of 2022 to understand the impact of the COVID-19 pandemic on the motivation of teachers.
Abstract: When we first heard talking about COVID-19, nobody could foresee a pandemic with such giant proportions. No organization or institution was ready to face the natural effects that result from social distance and isolation schools that in the majority didn’t have the necessary support to provide immediate remote teaching or distance teaching. In the presence of a transition to remote emergency teaching, it is important to understand the impact it had on the motivation of basic and secondary school teachers, considering that there are already studies focusing on the impact it had on education or pupils/youngsters. To that end, a questionnaire was applied to teachers of basic and secondary education between the 3rd and the 31st of January of 2022. The results point to a decrease in the motivation of teachers during the pandemic period. Despite this matter, the interpersonal relationships existing at school, the collective and partnered work developed with teachers at the school regardless of the grade, level of education and formative option; the acknowledgment by their peers; the acknowledgment by the director, are seen as factors for the rise of teacher motivation in that time.

TL;DR: Taxes are dull. They are boring. Nobody wants to think about them; fewer want to have to pay them as mentioned in this paper . But like the sewage system, we must have a tax system that is both efficient and effective.
Abstract: Taxes are dull. They are boring. Nobody wants to think about them; fewer want to have to pay them. However, like the sewage system, we must have a tax system that is both efficient and effective. Because MMT shows that "taxes drive money", many believe that taxation is central to the MMT approach. Because MMT shows that "taxes don't pay for government spending", others believe MMT ignores taxation. In this chapter, we set the record straight, put tax in its proper place behind the other MMT stabilisation mechanisms, and adjust the UK taxation system to manage the financial effluent efficiently and effectively.

TL;DR: Gould's Where Echoes Die as discussed by the authors is a deeply felt story about an inescapable loss, where the protagonist, Beck, visits Backravel, a small, easy-to-overlook town in Arizona on which she took meticulous notes, describing in detail nearly every aspect of the dusty, forgotten place.
Abstract: Reviewed by: Where Echoes Die by Courtney Gould Natalie Berglind Gould, Courtney Where Echoes Die. Wednesday/St. Martin's, 2023 [352p] Trade ed. ISBN 9781250825797 $20.00 E-book ed. ISBN 9781250825711 $11.99 Reviewed from digital galleys R Gr. 8-12 Beck's mother was obsessed with Backravel, a small, easy-to-overlook town in Arizona on which she took meticulous notes, describing in detail nearly every aspect of the dusty, forgotten place. It's those notes that drive Beck to visit Backravel in the wake of her mother's death, even if that means lying to her younger sister Riley about the purpose of their vacation there and lying to her dad about where they're going. Right away, Backravel reveals itself to be deeply unsettling: nobody drives around in cars, the host of the sisters' rented trailer forgets who they are, and a girl named Avery actively impedes Beck's investigation into the town's secrets. It's up to Beck to find out why this town guards itself so closely and what her mother was researching here—before her curiosity is discovered or Backravel consumes her like it did her mother. Gould treads familiar tropes well, with a timeless, secretive town, a complicated sister relationship, and sapphic subplots, all woven into a deeply felt story about an inescapable loss. Riley stepping in during Beck's panic attacks while she herself is mourning is as realistically complex as it is heartbreaking, and though Beck often gets herself into tough situations through her curiosity, her grief permeates the novel and justifies her motivations on her quest for the truth. Mystery fans who crave creepy atmospheres are sure to savor the slow unspooling of Backravel's dark truths. Copyright © 2023 The Board of Trustees of the University of Illinois

TL;DR: This article found that drivers either overpay or underpay for parking at on-street parking meters 94 % or 98 % of the time, in the survey study and field study respectively, for 20-30 min on average in the field study.
Abstract: The existing parking system assumes that drivers can pay the right price for parking, but we find the opposite in a field study (N = 567) and a survey study (N = 474). Drivers either overpaid or underpaid for parking at on-street parking meters 94 % or 98 % of the time, in the survey study and field study respectively, for 20–30 min on average in the field study. Such misalignment between parking payments and presumed price can mask the price signal and reduce its ability to influence drivers’ behavior and downstream environmental consequences. We also find that the public prefers an alternative, intelligent payment system that automatically collects on-street parking fees based on actual parking durations. These findings provide evidence for widespread parking payment inaccuracy and suggest an opportunity for public policy and technology to address the problem. This research offers important insights for transportation and planning professionals on the future of parking.

Abstract: This paper introduces a framework for a quantum description of spacetime inspired by Presentism and Information Theory. We start from a fundamental thick present instant as the only element of reality in time and map space to a relational lattice evolving in atomic instants. Then, we mathematically derive the emergence of a flat spacetime from the sampling of discrete information in each instant, holographically bounded by the number of instants considered. We elaborate on the probabilistic nature of time dilations in the proposed framework and conclude suggesting next steps towards a quantum description of curved spacetime. Our proposal connects two seemingly opposite perspectives (“the proper experience of time is relativistic” and “only the Present exists”), leading Heraclit of Efes, Plato, and Einstein, eventually on the same page.

TL;DR: In this article , the authors discuss different aspects of the UAT phase of a software development project, depending on the stage of the project, and emphasize the right things and avoid talking about some other aspects while some are just ignored altogether.
Abstract: Depending on the stage of the project, different aspects are emphasized. During the sales and initiation phase, the competencies and experience of several key people are stressed, and relations and trust are built. During the analysis stage, the work is mainly done “on paper” and in a virtual way. It’s still important to demonstrate knowledge and experience; a handful of people are involved. Then, when the development starts, we move to a phase when the client cares about concrete outcomes, we focus on numbers, performance, velocity. Depending on the selected methodology, the client is more or less involved in giving feedback and creating some final solution. Relations with the key analysts are less important than the outcomes of the development work. The closer we get to the stage of UAT, the more we focus on the discussions related to what is in the scope and what isn’t. Individuals don’t matter (that much) anymore, the client can see the software that was delivered and directs his entire attention to “polishing,” which means ensuring that nothing is missing. Thus, it’s a period when both businesses look at the completeness of the delivered solution and how possible fixes will affect the final release date. Then the solution is deployed into production and there is time for stabilizing the system, the businesses start talking about SLA, the number of bugs in time, bug category, fixing times, etc. Nobody talks about the pace of development, the company’s competences, the number of people on the project. The client is only interested in quick fixing of the bugs, and even better that there are no bugs whatsoever or that their number does not exceed a certain limit. So, depending on the stage of the project, both the client is interested in monitoring other aspects of the project, and we also need to emphasize the right things and avoid talking about some other (for the sake of the project and of the client), while some are just ignored altogether.

TL;DR: In the 2003 Pixar animation Finding Nemo, a clownfish named Marlin is an overprotective father, and for good reason: he has recently gone through the trauma of losing both his wife and all their fertilized eggs save one as mentioned in this paper .
Abstract: In the 2003 Pixar animation Finding Nemo, a clownfish named Marlin is an overprotective father, and for good reason: he has recently gone through the trauma of losing both his wife and all their fertilized eggs save one. Nemo is his only remaining offspring, a son. On Nemo’s first day of school, he gets caught in a fishing net and is taken far away. Marlin spends the rest of the movie looking for Nemo. He gets to know a variety characters in his search, some providing comic relief, some providing leads. But in each interaction Marlin learns a more about himself, in particular, that he is too fearful and too protective. For some, Finding Nemo is about Nemo; for others, it is about Marlin. That is, instead of Marlin providing a subplot, he provides the central story. Finding Nemo is about Marlin’s personal journey of overcoming the trauma of losing his wife and almost-children. To give even more of a twist to a seemingly benign movie, there is a theory bouncing around on the Internet that Marlin imagines Nemo and everything that happens in the movie is only imagined. That is, he makes up Nemo to cope with his loss. This theory has some merit as Nemo means “nobody” in Latin. Amir D. Aczel is a professor of statistics. He has a doctorate

TL;DR: In this article , BMP2 mRNA was enriched into exosomes by selective inhibition of translation in donor cells, in which NoBody (non-annotated P-body dissociating polypeptide, a protein that inhibits mRNA translation) and modified engineered BMP 2 plasmids were co-transfected.
Abstract: Sustained release of bioactive BMP2 (bone morphogenetic protein-2) is important for bone regeneration, while the intrinsic short half-life of BMP2 at protein level cannot meet the clinical need. In this study, we aimed to design Bmp2 mRNA-enriched engineered exosomes, which were then loaded into specific hydrogel to achieve sustained release for more efficient and safe bone regeneration.Bmp2 mRNA was enriched into exosomes by selective inhibition of translation in donor cells, in which NoBody (non-annotated P-body dissociating polypeptide, a protein that inhibits mRNA translation) and modified engineered BMP2 plasmids were co-transfected. The derived exosomes were named ExoBMP2+NoBody. In vitro experiments confirmed that ExoBMP2+NoBody had higher abundance of Bmp2 mRNA and thus stronger osteogenic induction capacity. When loaded into GelMA hydrogel via ally-L-glycine modified CP05 linker, the exosomes could be slowly released and thus ensure prolonged effect of BMP2 when endocytosed by the recipient cells. In the in vivo calvarial defect model, ExoBMP2+NoBody-loaded GelMA displayed great capacity in promoting bone regeneration.Together, the proposed ExoBMP2+NoBody-loaded GelMA can provide an efficient and innovative strategy for bone regeneration.
