Cognitive exertion affects the appraisal of one’s own and other people’s pain
Correctly evaluating others’ pain is a crucial prosocial ability. In both clinical and private settings, caregivers assess their other people’s pain, sometimes under the effect of poor sleep and high workload and fatigue. However, the effect played by such cognitive strain in the appraisal of others’ pain remains unclear. Fifty participants underwent one of two demanding tasks, involving either working memory (Experiment 1: N-Back task) or cognitive interference (Experiment 2: Stroop task). After each task, participants were exposed to painful laser stimulations at three intensity levels (low, medium, high), or video-clips of patients experiencing three intensity levels of pain (low, medium, high). Participants rated the intensity of each pain event on a visual analogue scale. We found that the two tasks influenced rating of both one’s own and others’ pain, by decreasing the sensitivity to medium and high events. This was observed either when comparing the demanding condition to a control (Stroop), or when modelling linearly the difficulty/performance of each depleting task (N-Back). We provide converging evidence that cognitive exertion affects the subsequent appraisal of one’s own and likewise others’ pain
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
We create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
Abstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
STUDY OF PROCESS OF HARDENING OF GYPSUM BINDERS, MIXING BY WATER, ACTIVATED BY MICROWAVE ELECTROMAGNETIC FIELD
In this work, the effect of microwave (WV) radiation on the structure of distilled water is investigated, which is proved by the change in its electrical conductivity and coefficient of viscosity. Intensification of chemical processes with microwave radiation is the result of the electromagnetic field affecting the solvent and interacting substances. The process of hydration of semi-aquatic gypsum, which was closed by microwave-treated water with different values of the inputted energy in comparison with the control sample, was studied by the electric resistance measurement method. The kinetics of hydration and hardening of gypsum suspension was also studied. Differentiation methods yielded curves characterizing the stages of hardening of a gypsum binder: dissolution, colloidation, coagulation and crystallization. It is proved that, depending on the amount of microwave energy absorbed by distilled water, the duration of gypsum hardening processes changes. Optimal modes of microwave water treatment have been selected, which help to regulate the hardening process of gypsum binders. It is considered that to shutting gypsum binders, it is advisable to use a shutter with reduced electrical conductivity and, accordingly, with a minimum value of the viscosity coefficient. The destruction of the water structure or its change due to the influence of the microwave field will apparently influence the structure formation during hardening of the gypsum samples and, as a consequence, the change in their strength. The physic-mechanical properties of gypsum samples (bending and compression strength) are studied. The application of microwave radiation during processing of distilled water intensified the hardening process of semi-fluid calcium sulfate, contributed to an increase in the strength characteristics of the finished gypsum samples. The results of the experiment testify show the promising use of microwave water treatment, for the subsequent blocking of air binders and the obtaining building materials of greater strength.Forcitation:Pavlenko V.I., Lapteva S.N.

The Impact of COVID-19 on doctors well-being: Results of a web survey during the lockdown in Italy
OBJECTIVE: On March 12, 2020, the World Health Organization (WHO) declared the outbreak of a new Coronavirus disease (COVID-19), to be a pandemic. From the be- ginning, Italy (in particular the Northern re- gions) was the first large European country to be hit and one of the most affected coun- tries worldwide. This had a significant impact on the workload and psychological health of health workers. The aim of this web-based cross-sectional study is to assess the con- sequences of the COVID-19 pandemic on Ital- ian doctors’ well-being and psychological dis- tress, in respect of demographic and occu- pational characteristics, lifestyle and habits during the lockdown period.PATIENTS AND METHODS: We conducted a web-based cross-sectional survey based on Google® Forms to collect data. The participa- tion was available during the lockdown period that started in Italy on March 9, 2020 and it was voluntary and anonymous. The question- naire explored demographic and occupational variables, lifestyle and habits during the lock- down, perceived well-being and psychological distress. Multivariate logistic regression models were fitted.
RESULTS: Our study reported the very alarm- ing psychological conditions of Italian doctors, especially among those who worked in the most affected regions, where a level of psychological distress of 93.8% and poor well-being of 58.9% were registered. These percentages were even higher in the case of female hospital workers with low job seniority, and those caring for COVID-19 patients.
CONCLUSIONS: Our findings reported a sig- nificant psychosocial impact of the COVID-19 outbreak on Italian doctors, particularly among those working in the most affected regions of the country. Further studies are necessary to better understand the effects of the COVID-1
Diffusive author(s), cohesive author: Analysis of S/N (1994)
This study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Pharmacists' mental health during the SARS-CoV-2 pandemic in Italy
OBJECTIVE: The year 2020 was characterized by the outbreak of a new pandemic caused by a novel coronavirus named SARSCoV- 2. To face the pandemic, many countries worldwide imposed general lockdowns, closing all non-essential businesses. As primary care services, pharmacies had to remain open, thus putting pharmacy staff at significant risk of viral infection and overwork. This study aimed to assess the mental health of Italian Pharmacists, considering demographic and occupational characteristics, lifestyle, and habits, during the SARS-CoV-2 outbreak and the subsequent lockdown period (March-May 2020). MATERIALS AND METHODS: A web-based survey was created using Google® Forms to collect data from March 30, 2020, to June 1, 2020. The questionnaire consisted of three sections investigating: (1) demographic and occupational variables, (2) lifestyle and habits variables, (3) psychological distress and perceived well-being. RESULTS: A total of 401 participants completed the questionnaire. Older workers and those with more work experience reported more psychological stress. Older and female workers, who felt lonely at home and reported psychological stress, perceived poor well-being. CONCLUSIONS: Our findings demonstrate that the Sars-CoV-2 outbreak and subsequent lockdown rules affected pharmacists' mental health and that it is important to put in place preventive measures against the occurrence of mental disorders among them
Finite sample corrections for average equivalence testing
Average (bio)equivalence tests are used to assess if a parameter, like the mean difference in treatment response between two conditions for example, lies within a given equivalence interval, hence allowing to conclude that the conditions have "equivalent" means. The two one-sided tests (TOST) procedure, consisting in testing whether the target parameter is respectively significantly greater and lower than some pre-defined lower and upper equivalence limits, is typically used in this context, usually by checking whether the confidence interval for the target parameter lies within these limits. This intuitive and visual procedure is however known to be conservative, especially in the case of highly variable drugs, where it shows a rapid power loss, often reaching zero, hence making it impossible to conclude for equivalence when it is actually true. Here, we propose a finite sample correction of the TOST procedure, the alpha-TOST, which consists in a correction of the significance level of the TOST allowing to guarantee a test size (or type-I error rate) of alpha. This new procedure essentially corresponds to a finite sample and variability correction of the TOST procedure. We show that this procedure is uniformly more powerful than the TOST, easy to compute, and that its operating characteristics outperform the ones of its competitors. A case study about econazole nitrate deposition in porcine skin is used to illustrate the benefits of the proposed method and its advantages compared to other available procedures
