The coronavirus disease pandemic fundamentally disrupted humans’ social life and behavior. Public health measures may have inadvertently impacted how people care for each other. This study investigated prosocial behavior, its association well-being, and predictors of prosocial behavior during the first COVID-19 pandemic lockdown and sought to understand whether region-specific differences exist. Participants from eight regions clustering multiple countries around the world responded to a cross-sectional online-survey investigating the psychological consequences of the first upsurge of lockdowns in spring 2020. Prosocial behavior (...) was reported to occur frequently. Multiple regression analyses showed that prosocial behavior was associated with better well-being consistently across regions. With regard to predictors of prosocial behavior, high levels of perceived social support were most strongly associated with prosocial behavior, followed by high levels of perceived stress, positive affect and psychological flexibility. Sociodemographic and psychosocial predictors of prosocial behavior were similar across regions. (shrink)

Background: Nursing students on clinical placements as part of their professional training are routinely faced with situations involving ethical conflicts. The initial act of perceiving a situation as causing an ethical dilemma is the result of both the students’ personal values, drawn from their culture and families, and of the professional knowledge and values that they have acquired through training and experience. Objectives: Nursing students’ experiences on clinical placements in primary care settings were investigated in order to identify situations that (...) they perceived as involving ethical conflict and describe the elements they took into consideration during their decision-making processes in these situations. Methods: The research design was qualitative descriptive case study. Around 50 students from three different intakes to a nursing degree answered a questionnaire and discussed it in focus groups. Ethical considerations: The study was designed in accordance with the principles guiding research with human beings and was approved by the Human Research Ethics Committee. Results: Synthesised into two principal axes: (a) ethical conflicts in primary care, linked with the domains of working processes, professional nursing ethics and human and social rights and (b) students’ decision-making processes – realisation, reflection and intervention. Conclusion: The student nurses saw themselves both as actors and spectators in situations involving ethical problems and demanding moral deliberation, demonstrating the ability to base their arguments soundly. They tended to emphasise the possibilities offered by dialogue and that different ethical values must be respected to find fair solutions to ethical problems. (shrink)

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

The standard approach for abstractive text summarization is to use an encoder-decoder architecture. The encoder is responsible for capturing the general meaning from the source text, and the decoder is in charge of generating the final text summary. While this approach can compose summaries that resemble human writing, some may contain unrelated or unfaithful information. This problem is called “hallucination” and it represents a serious issue in legal texts as legal practitioners rely on these summaries when looking for precedents, used (...) to support legal arguments. Another concern is that legal documents tend to be very long and may not be fed entirely to the encoder. We propose our method called LegalSumm for addressing these issues by creating different “views” over the source text, training summarization models to generate independent versions of summaries, and applying entailment module to judge how faithful these candidate summaries are with respect to the source text. We show that the proposed approach can select candidate summaries that improve ROUGE scores in all metrics evaluated. (shrink)

In order to understand the rise of runaway solutions in the radiation reaction problem a mechanical model is used. An alternative demonstration of Daboul’s theorem, through Hurwitz’s criterion, is given. The origin of runaway solutions in electrodynamics is discussed. They arise when the particle has a negative mechanical mass or when approximations are used in the equation of motion. In the 1-dimensional mechanical model an exact and linear equation of motion for the particle is obtained, the corresponding exact solution is (...) again runaway when the mechanical mass is negative. The exact solution is not runaway when the mechanical mass is positive. However, the use of approximations leads to an equation of motion which has runaway solutions. It is exhibited that the use of approximations in the 3-dimensional mechanical model is completely necessary because the general equation of motion for the particle is non-linear. The analysis of this case proceeds in a very similar way to the one carried out in electrodynamics. This means that the number of dimensions also plays an important role in the analysis. (shrink)

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

Good academic practice is more than the avoidance of clear-cut cheating. It also involves navigation of the gray zones between cheating and good practice. The existing literature has left students’ understanding of gray zone practices largely unexplored. To begin filling in this gap, we present results from a questionnaire study involving N = 1639 undergraduate students from seven European countries representing all major disciplines. We show that large numbers of these students are unable to identify gray area issues and lack (...) sensitivity to the context dependence of these. We also show that a considerable proportion of students have a poor understanding of concepts like plagiarism and falsification, not only in gray zone scenarios, but also in cases of relatively clear-cut cheating. Our results are similar across the faculties and countries of study, and even for students who have attended academic integrity training. We discuss the implications of this for academic integrity training. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Philosophies of America Reader: From the Popol Vuh to the Present ed. by Kim Díaz and Mathew A. FoustBernardo R. Vargas (bio)The Philosophies of America Reader: From the Popol Vuh to the Present. Edited by Kim Díaz and Mathew A. Foust. New York: Bloomsbury, 2021. Pp. 480. Paperback $46.75, isbn 978-1-4742-9626-7.Philosophy in the United States continues to be among the least diverse disciplines in the humanities, (...) dominated statistically by white males, with the next largest group being white female philosophers.1 This lack of diversity affects how we define philosophy and who counts as a philosopher. As the editors of The Philosophies of America Reader, Kim Díaz and Mathew A. Foust, put it, "Just as history has fashioned and popularized distorted accounts of the 'discovery' of America, it has done the same in its presentation of American Philosophy" (p. xv). This exemplary collection of essays from across the Americas allows the readers and instructors to reimagine what we construe as philosophy and who we imagine an American philosopher to be.The editors offer diverse essays covering an impressive timeframe, ranging from the Popol Vuh, whose oral tradition from Guatemala predates Spanish colonization and was recorded in the mid-1500s, to contemporary philosophers such as Gregory Pappas. The collection excels in offering texts that typical philosophy anthologies are unlikely to include, which the editors call "unusual suspects" that have been historically marginalized, while also maintaining more familiar or "classical" figures (pp. xv–xvi). These "unusual suspects" include women, Latinx, American Indigenous, Black, and Caribbean thinkers.The Philosophies of America Reader offers various resources to enhance the student and instructor's experience. The book is structured into four themes: (1) Selfhood and Identity, (2) Knowing and Learning, (3) Aesthetics and Spirituality, and (5) Violence and Peace. The editors design these themes to fit the traditionally understood areas of philosophy of metaphysics, epistemology, and axiology. Even if the instructor's course description does not specifically target American Philosophy, these thematic categories are valuable for th ose who wish to incorporate a more diverse reading list. For example, these essays could easily apply to courses such as Critical Philosophy of Race, Introduction to Philosophy, or Introduction to Ethics. Each thematic section also features a "For Further Reading" segment, which includes selected secondary sources to broaden research or substitute texts. In addition, the editors provide a detailed [End Page 1] syllabus example, including a Course Description and Outline of the Course for a bi-weekly class, which is neatly divided into a 16-week reading schedule. They also include instructive sections such as a Note to the Teacher to aid in thinking through how to interact with the unfamiliar texts and a Note to the Student to guide their disposition and readings.Moreover, the text presents introductory essays for each thematic section. These essays provide an overview of the content and delve into the author's positionality, such as their geography, context, motivations for writing, race, ethnicity, and native tongue. The introductions are philosophically robust yet accessible to new philosophy students and are not filled with unnecessary philosophical jargon.Due to its large scope of thinkers, this text offers a vibrant opportunity to dialogue with philosophers who share or differ in their perspectives across the major thematic categories. The editors emphasize that although this is not a history of thought, the texts present lineages of progression, elaboration, and disagreement intended to guide instructors in connecting the texts with their students (p. xx). Furthermore, this allows the reader and the instructor to avoid isolating their discourse to a particular time, geography, gender, or race and ethnicity. In addition to the biographical and contextual information given in the introductions, a small yet helpful detail is a timeline of the selections that further contextualizes the readings.I wish to underscore two key clusters of essays amidst the vast array of 50 readings related to Asian-American and Mexican-American discourse for the instructor's consideration, particularly those teaching in the United States. These two large population groups deserve consideration as enrollment rates for Asian Americans and Hispanics (of whom Mexicans are the largest population... (shrink)

The only test theory used by workers in the field of testing special relativity to analyze the significance of their experiments is the proof by H. P. Robertson [Rev. Mod. Phys. 21, 378 (1949)] of the Lorentz transformations from the results of the experimental evidence. Some researchers would argue that the proof contains an unwarranted assumption disguised as a convention about synchronization procedures. Others would say that alternative conventions are possible. In the present paper, no convention is used, but the (...) Lorentz transformations are still obtained using only the results of the experiments in Robertson's proof, namely the Michelson-Morley, Kennedy-Thorndike, and Ives-Stilwell experiments. Thus the revised proof is a valid test theory which is independent of any conventions, since one appeals only to the experimental evidence. The analysis of that evidence shows the directions in which efforts to test special relativity should go. Finally it is shown how the resulting test theory still has to be improved for consistency in the analysis of experiments with complicated experimental setups, how it can be simplified for expediency as to what should be tested, and how it should be completed for a missing step not considered by Robertson.

The experimental testing of the Lorentz transformations is based on a family of sets of coordinate transformations that do not comply in general with the principle of equivalence of the inertial frames. The Lorentz and Galilean sets of transformations are the only member sets of the family that satisfy this principle. In the neighborhood of regular points of space-time, all members in the family are assumed to comply with local homogeneity of space-time and isotropy of space in at least one (...) free-falling elevator, to be denoted as Robertson'sab initio rest frame [H. P. Robertson,Rev. Mod. Phys. 21, 378 (1949)].Without any further assumptions, it is shown that Robertson's rest frame becomes a preferred frame for all member sets of the Robertson family except for, again, Galilean and Einstein's relativities. If one now assumes the validity of Maxwell-Lorentz electrodynamics in the preferred frame, a different electrodynamics spontaneously emerges for each set of transformations. The flat space-time of relativity retains its relevance, which permits an obvious generalization, in a Robertson context, of Dirac's theory of the electron and Einstein's gravitation. The family of theories thus obtained constitutes a covering theory of relativistic physics.A technique is developed to move back and forth between Einstein's relativity and the different members of the family of theories. It permits great simplifications in the analysis of relativistic experiments with relevant “Robertson's subfamilies.” It is shown how to adapt the Clifford algebra version of standard physics for use with the covering theory and, in particular, with the covering Dirac theory.

El instrumento fue el Inventario de (...) Ansiedad de Beck (BAI) compuesto por 21 ítems aplicado mediante un formulario virtual, anónimo, confidencial y voluntario. Los resultados arrojaron que el 73,7% de docentes no tiene presencia de ansiedad, un 21,1% un nivel leve y un 5,3% presentó un nivel moderado. Se pudo comprobar que no existen diferencias significativas en cuanto a la ansiedad entre los docentes de estas dos universidades; habiéndose obtenido un p valor de 0,275. Las conclusiones el mayor porcentaje de docentes de ambas universidades no evidencian síntomas relacionados a ansiedad. Finalmente, queda pendiente que investigaciones futuras continúen comparando los niveles de ansiedad. (shrink)

BackgroundTraumatic brachial plexus injury (TBPI) causes a sensorimotor deficit in upper limb (UL) movements.ObjectiveOur aim was to investigate the arm–forearm coordination of both the injured and uninjured UL of TBPI subjects.MethodsTBPI participants (n = 13) and controls (n = 10) matched in age, gender, and anthropometric characteristics were recruited. Kinematics from the shoulder, elbow, wrist, and index finger markers were collected, while upstanding participants transported a cup to their mouth and returned the UL to a starting position. The UL coordination (...) was measured through the relative phase (RP) between arm and forearm phase angles and analyzed as a function of the hand kinematics.ResultsFor all participants, the hand transport had a shorter time to peak velocity (p < 0.01) compared to the return. Also, for the control and the uninjured TBPI UL, the RP showed a coordination pattern that favored forearm movements in the peak velocity of the transport phase (p < 0.001). TBPI participants' injured UL showed a longer movement duration in comparison to controls (p < 0.05), but no differences in peak velocity, time to peak velocity, and trajectory length, indicating preserved hand kinematics. The RP of the injured UL revealed altered coordination in favor of arm movements compared to controls and the uninjured UL (p < 0.001). Finally, TBPI participants' uninjured UL showed altered control of arm and forearm phase angles during the deceleration of hand movements compared to controls (p < 0.05).ConclusionThese results suggest that UL coordination is reorganized after a TBPI so as to preserve hand kinematics.

Background Health advocacy is crucial for both patients and healthcare professionals. However, nurses who recognize the importance of health advocacy may experience heightened moral distress, particularly in complex donation and transplantation cases where patient autonomy, respect, and advocacy are paramount. Aim To identify the factors contributing to moral distress among nurses working in solid organ transplant units at a university hospital in São Paulo, with a focus on health advocacy. Research Design This descriptive, cross-sectional study employs both quantitative and qualitative (...) methods. For this, the quantitative phase of the study was conducted utilizing the Moral Distress Scale, while the qualitative phase was executed through focus group discussions. Participants and Research Context The quantitative phase involved 15 nurses using the Moral Distress Scale. The qualitative phase consisted of a focus group with 5 nurse managers/coordinators from the transplant units. Quantitative data were analyzed using R® software, while qualitative data were analyzed using Bardin’s Content Analysis. Ethical Considerations The study was approved by the Research Ethics Committee of the Ribeirão Preto College of Nursing, University of São Paulo. Participation was voluntary and confidentiality was ensured. Results A significant correlation was found between moral distress and the factors of “disregard for patient autonomy” ( p =.0100) and “therapeutic obstinacy” ( p =.0492). Conclusion The primary determinants associated with moral distress in the context of health advocacy were identified as “disregard for patient autonomy” and “therapeutic obstinacy.”. (shrink)

A continuoxis t- norm is a continuous map * from [0, 1]² into [0,1] such that is a commutative totally ordered monoid. Since the natural ordering on [0,1] is a complete lattice ordering, each continuous t-norm induces naturally a residuation → and becomes a commutative naturally ordered residuated monoid, also called a hoop. The variety of basic hoops is precisely the variety generated by all algebras, where * is a continuous t-norm. In this paper we investigate the structure of the (...) variety of basic hoops and some of its subvarieties. In particular we provide a complete description of the finite subdirectly irreducible basic hoops, and we show that the variety of basic hoops is generated as a quasivariety by its finite algebras. We extend these results to Hájek's BL-algebras, and we give an alternative proof of the fact that the variety of BL-algebras is generated by all algebras arising from continuous t-norms on [ 0,1] and their residua. The last part of the paper is devoted to the investigation of the subreducts of BL- algebras, of Gödel algebras and of product algebras. (shrink)

La primera parte se titula: “Fenomenología de la fenomenología”, cuestión presente desde los orígenes mismos de la fenomenología y preocupación constante de su fundador. En esta parte se abordan tres estudios muy diversos, cuyo eje es el interés por contribuir, sin pretensión de sistematicidad, a una meta-fenomenología. En el primer estudio, el autor se aproxima a una de las preguntas más vitales de la fenomenología, esto es, si existe o no un método fenomenológico. Luego de aclarar las dificultades históricas, epistemológicas (...) y metodológicas (estas últimas llamadas por el autor “procedimentales”) para atreverse a responder a esta pregunta, Vargas Guillén llega a la tesis de su estudio: “la fenomenología, que esencialmente es método, tiene principios, pero no procedimientos” (p. 14). De una manera clara, difícil de encontrar en la mayoría de los textos fenomenológicos, y respaldado en didácticos esquemas, el autor se dedica a explicar cada uno de los “postulados o principios metodológicos de la fenomenología”, cerrando el estudio con unas polémicas sugerencias.

Sin duda el ensayo escrito en forma epistolar no es una propuesta original en el escenario de la literatura contemporánea: fue difundido en época romana, se consolidó a inicios del siglo xx con Rainer María Rilke y más recientemente lo han vuelto a proponer Mario Vargas Llosa, Maurice Béjart, Edward O. Wilson. Sin embargo, Cartas a una joven ensayista de Efrén Giraldo, que se dirige específicamente a una ensayista inexperta, resulta pionero en su género.
