Abstract
Background
The capacity to evaluate beauty plays a crucial role in social behaviour and social relationships. It is known that some characteristics of beauty are important social cues that can induce stereotypes or promote different behavioural expectations. Another crucial capacity for success in social interactions is empathy, i.e. the ability to understand and share others’ mental and emotional states. Individuals with Autism Spectrum Disorder (ASD) have an impairment of empathic ability. We showed in a previous study that empathy and aesthetic perception abilities closely related. Indeed, beauty can affect different aspects of empathic behaviour, and empathy can mediate the aesthetic perception in typically developing (TD) individuals. Thus, this study evaluates the ability of aesthetic perception in ASD individuals compared to TD individuals, using the Golden Beauty behavioural task adapted for eye-tracking in order to acquire both explicit and implicit evidences. In both groups, the relationship between empathic and aesthetic perception abilities was also evaluated.

Methods
Ten ASD individuals (age ± SD:20.7 ± 4.64) and ten TD individuals (age ± SD:20.17 ± 0.98) participated in the study. Participants underwent empathy tasks and then the Golden Beauty task. To assess differences in the participants’ performance, we carried out a repeated measures general linear model.

Results
At the explicit level, our behavioural results show an impairment in aesthetic perception ability in ASD individuals. This inability could have relevance for their ability to experience pleasure during social interactions. However, at the implicit level (eye-tracking results), ASD individuals conserved a good ability to feel aesthetic pleasure during the Golden Beauty task, thus indicating a discrepancy between the explicit and implicit evaluation of the beauty task. Finally, beauty perception appears to be linked to empathy when neither of these capacities is compromised, as demonstrated in the TD group. In contrast, this link is missed in ASD individuals.

Conclusion
Overall, our results clearly show that individuals with autism are not completely blind to aesthetic pleasure: in fact, they retain an implicit ability to experience beauty. These findings could pave the way for the development of new protocols to rehabilitate ASD social functioning, exploiting their conserved implicit aesthetic perception.

High Security and Capacity of Image Steganography for Hiding Human Speech Based on Spatial and Cepstral Domains
Authors: Khaleel Yazen A. 
Published: July 2020

A new technique of hiding a speech signal clip inside a digital color image is proposed in this paper to improve steganography security and loading capacity. The suggested technique of image steganography is achieved using both spatial and cepstral domains, where the Mel-frequency cepstral coefficients (MFCCs) are adopted, as very efficient features of the speech signal. The presented technique in this paper contributes to improving the image steganography features through two approaches. First is to support the hiding capacity by the usage of the extracted MFCCs features and pitches extracted from the speech signal and embed them inside the cover color image rather than directly hiding the whole samples of the digitized speech signal. Second is to improve the data security by hiding the secret data (MFCCs features) anywhere in the host image rather than directly using the least significant bits substitution of the cover image. At the recovering side, the proposed approach recovers these hidden features and using them to reconstruct the speech waveform again by inverting the steps of MFCCs extraction to recover an approximated vocal tract response and combine it with recovered pitch based excitation signal. The results show a peak signal to noise ratio of 52.4 dB of the stego-image, which reflect a very good quality and a reduction ratio of embedded data to about (6%–25%). In addition, the results show a speech reconstruction degree of about 94.24% correlation with the original speech signal.
A Struggle with Alterity: A Lévinasian Reading ofMacbeth
Authors: Bidgoli Mehrdad , Royanian Shamsoddin 
Published: July 2020

AbstractInMacbeth(ca. 1606), William Shakespeare returns all the way back to his metaphysics which he had demonstrated magnificently inA Midsummer Night’s Dream(ca. 1595) andHamlet(ca. 1600). These works represent Shakespeare’s dramaturgical treatment of Being, substance, essence, etc. One of the chief elements of these plays is supernaturality, or nothingness (non-being) in a sense interrupting Being and human activities. These elements are presented inJulius Caesar(1599) as well, a history play which has commonalities withMacbeth. Yet few of his tragedies offer a world so dipped in horror and darkness asMacbeth. Ethics might thus be a far-fetched component among these grisly sensations and in the bloody atmosphere of this tragedy, but with the help of Emmanuel Lévinas (1906–1995), traces of ethical exigency can be discerned. ApproachingMacbeththrough Lévinas’s philosophy, we attempt to study some ways in which ethics can be addressed and studied in this dark world. We will discuss Macbeth’s struggles with time (mostly his future) and the Other as metaphors of alterity intruding into and interrupting his totalizing conatus.
A Comment on Arrow’s Impossibility Theorem
Authors: Sandroni Alec , Sandroni Alvaro 
Published: July 2020

Abstract
Arrow (1950) famously showed the impossibility of aggregating individual preference orders into a social preference order (together with basic desiderata). This paper shows that it is possible to aggregate individual choice functions, that satisfy almost any condition weaker than WARP, into a social choice function that satisfy the same condition (and also Arrow’s desiderata).
A microelectromechanical system (MEMS) capacitive accelerometer-based microphone with enhanced sensitivity for fully implantable hearing aid: a novel analytical approach
Authors: Dwivedi Apoorva , Khanna Gargi 
Published: July 2020

Abstract
The present work proposes a novel, compact, intuitively simple and efficient structure to improve the sensitivity of a microelectromechanical system (MEMS) capacitive accelerometer using an arrangement of microlever as a displacement amplifier. The accelerometer is proposed to serve as a microphone in the fully implantable cochlear prosthetic system which can be surgically implanted at the middle ear bone structure. Therefore, the design parameters such as size, weight and resonant frequency require deliberation. The paper presents a novel analytical model considering the impact of the mechanical amplification along with the width of the microlever and the capacitive fringe effects on the performance of the sensor. The design is simulated and verified using COMSOL MULTIPHYSICS 4.2. The accelerometer is designed within a sensing area of 1 mm2 and accomplishes a nominal capacitance of 4.85 pF and an excellent sensitivity of 5.91 fF/g.
An integrated assessment system for the accreditation of medical laboratories
Authors: Saleh Neven , Abo Agyla Ahmed 
Published: July 2020

Abstract
Medical laboratory accreditation becomes a trend to be trustable for diagnosis of diseases. It is always performed at regular intervals to assure competence of quality management systems (QMS) based on pre-defined standards. However, few attempts were carried out to assess the quality level of medical laboratory services. Moreover, there is no realistic study that classifies and makes analyses of laboratory performance based on a computational model. The purpose of this study was to develop an integrated system for medical laboratory accreditation that assesses QMS against ISO 15189. In addition, a deep analysis of factors that sustain accreditation was presented. The system started with establishing a core matrix that maps QMS elements with ISO 15189 clauses. Through this map, a questionnaire was developed to measure the performance. Therefore, score indices were calculated for the QMS. A fuzzy logic model was designed based on the calculated scores to classify medical laboratories according to their tendency for accreditation. Further, in case of failure of accreditation, cause-and-effect root analysis was done to realize the causes. Finally, cloud computing principles were employed to launch a web application in order to facilitate user interface with the proposed system. In verification, the system has been tested using a dataset of 12 medical laboratories in Egypt. Results have proved system robustness and consistency. Thus, the system is considered as a self-assessment tool that demonstrates points of weakness and strength.
Glycophorin A-based exclusion of red blood cells for flow cytometric analysis of platelet glycoprotein expression in citrated whole blood
Authors: Berens Christina , Oldenburg Johannes , Pötzsch Bernd , Müller Jens 
Published: July 2020

Abstract

Objectives
Analysis of platelet glycoprotein (GP) expression by flow cytometry is applied for diagnostic confirmation of GP-associated thrombocytopathies. While platelet-rich plasma may be used for distinct identification of target events, this strategy is not feasible for small sample volumes or for patients showing low platelet counts and/or giant platelets. However, also the use of whole blood (WB) is hampered by the difficulty to discriminate platelets from red blood cells (RBC) in such patients. To circumvent these limitations, we evaluated the feasibility of a RBC gating-out strategy.

Methods
In addition to platelet GPIb, GPIIa/IIIa, as well as P-selectin (CD62P), citrated whole blood (CWB) samples were stained for RBC-specific glycophorin A (CD235a). CD235a-negative platelet events were further discriminated by forward-/side-scatter characteristics and platelet GP expressions analyzed relative to that of a healthy control sample processed in parallel.

Results
Established reference intervals allowed for clear identification of decreased GPIIb/IIIa- or GPIb expression pattern in samples of patients with confirmed Glanzmann thrombasthenia or Bernard–Soulier syndrome, respectively. It could be shown that the analysis of 2,500 platelet events is sufficient for reliable GP expression analysis, rendering the proposed method applicable to samples with low platelet counts.

Conclusions
This study demonstrates the feasibility of CD235a-based exclusion of RBC for platelet GP expression analysis in CWB. In contrast to direct staining of platelet-specific antigens for target identification, this indirect gating out approach is generally applicable independent of any underlying platelet GP expression deficiency.
Study design and ethical considerations related to using direct observation to evaluate physician behavior: reflections after a recent study
Authors: Berdahl Carl T. , Schriger David L. 
Published: July 2020

Abstract
In a recent study using direct observation of physicians, we demonstrated that physician-generated clinical documentation is vulnerable to error. In fact, we found that physicians consistently overrepresented their actions in certain areas of the medical record, such as the physical examination. Because of our experiences carrying out this study, we believe that certain investigations, particularly those evaluating physician behavior, should not rely on documentation alone. Investigators seeking to evaluate physician behavior should instead consider using observation to obtain objective information about occurrences in the patient-physician encounter. In this article, we describe our experiences using observation, and we offer investigators our perspectives related to study design and ethical questions to consider when performing similar work.

Published: July 2020

Abstract
The study examined the influence of impulsivity on undergraduates’ sexual risk behaviour and also scrutinized the mediating roles of family type and peer pressure on undergraduates’ sexual risk behaviour in Southwestern Nigeria. The study was a descriptive survey that employed a multi-stage sampling procedure in which respondents were selected at different levels and stages. A total of 1080 respondents selected from six Universities participated in the study. Their age ranges from 15-19 years with a mean of 15.9±1.2 years. Data gathered through Impulsive Behaviour Scale and the Sexual Behaviour Inventory was analysed by t-test and ANCOVA. The result showed that impulsivity (t = 6.04, df =1078, p <0.05) had significant influence on the sexual risk behaviour of undergraduates in Southwestern Nigeria. The result further showed that age: F (2, 1077) = 18.20, p < 0.05; family type F (2, 1077) = 25.41, p <0. 05 and peer pressure F (2, 1077) = 53.13, p< 0.05 have an intervening impact on the influence of impulsivity F (2, 1073) = 1.37, p < 0.05) on sexual risk behaviour of the undergraduates. The study concluded that impulsivity enhances sexual risk behaviour of undergraduates in Southwestern Nigeria.
The Pied Piper’s pipe
Authors: Thomson Ian 
Published: July 2020

AbstractThe story of the Pied Piper attracting rats and children away from the town of Hameln by playing music on a pipe is well known. Artists and writers inspired by the legendary magical qualities of the pipe have associated it with a variety of flutes, bagpipes, and whistles. However, scant academic attention has been paid to what kind of medieval pipe might actually have influenced this unusual story, nor indeed why a pipe, and not perhaps a string or brass instrument, was considered relevant. This essay examines the literature afresh, from musicological and cultural viewpoints.

Zusammenfassung
Der vorliegende Text verortet Nachhaltigkeit und Klimaschutz knapp in ihrem historischen Kontext und macht ihre aufeinander bezogene Entwicklung deutlich. Das beinhaltet sowohl eine Rekonstruktion der faktischen Genese als auch eine sachliche wie normative Begründung ihrer Wechselseitigkeit, die Nachhaltigkeits- und Klimapolitik zu zwei Seiten einer Medaille macht. Mit Blick auf den Prozess des Austauschs beider Diskurse und ihrer praktischen Effekte werden einerseits beachtliche globale Kooperations- und Lerngewinne sichtbar und andererseits die Mitverantwortung der Handelnden für den Erfolg komplexer Nachhaltigkeitstransformationen unterstrichen.
Zukünfte gestalten: Zivilgesellschaft in Wissenschafts- und Forschungspolitik beteiligen!
Authors: Ober Steffi , Burwitz Martin 
Published: July 2020

Zusammenfassung
Die Frage nach möglichen Zukünften für unsere Gesellschaft wird bisher in Forschungs- und Innovationsprojekten beantwortet, die von wirtschaftlichen Interessen und Technik-Fixierung geprägt sind. Doch der Klimawandel, Ressourcenübernutzung und die Probleme der Welternährung betreffen Menschen und Politik heute und zukünftig so grundlegend, dass sie mit ihren Werten und Zukunftsentwürfen die Leitlinien für wünschenswerte Technologieentwicklungen prägen sollten. Daher braucht Forschungspolitik zivilgesellschaftliche Perspektiven, die sich an nachhaltiger Entwicklung und sozialer Gerechtigkeit orientieren. Diese Orientierung fehlt bislang. Wir schlagen daher eine gesellschaftliche Charta für nachhaltige Innovationen vor, als eine Basis für die Frage nach wünschenswerten Zukünften – und somit für eine forschungspolitische Agenda, die sich an einer nachhaltigen Entwicklung orientiert.

Published: July 2020

Abstract

Background
Nurse educators are challenged to design courses that maintain rigor, promote student learning, maximize resource utilization, and ultimately prepare graduates for clinical practice.

Purpose
An innovative teaching strategy was used to educate BSN level students in nursing inquiry with a collaborative project.

Methods
Course faculty incorporated information literacy (IL) and evidence-based practice (EBP) competencies into an undergraduate research course by taking the traditional practicum research project and redesigning it as a longitudinal scoping review (ScR) collaborative project.

Results
At course conclusion, students verbalized having a deeper appreciation for nursing research, confidence in performing a literature search, and conducting a research critique.

Conclusions
The students’ contributions towards the ScR through their collaborative project work fostered personal growth in IL and EBP competencies through a meaningful project that can extend beyond the classroom to possibly influence patient care.
Measuring Tolerant Behavior
Authors: Liberati Caterina , Longaretti Riccarda , Michelangeli Alessandra 
Published: July 2020

Abstract
This paper addresses the issue of measuring tolerance, viewed as a multifaceted phenomenon involving several different social domains. We develop a multidimensional index for Likert-scale data, characterized by the following features: (i) it reflects the individual’s intensity of tolerant attitudes towards each social domain; (ii) the index can be broken down by dimension in order to determine the contribution of each dimension to overall tolerance; (iii) the index combines the different dimensions of tolerance using a weighted scheme that reflects the importance of each dimension in determining the overall level of tolerance. To show how this new measure of tolerance works in practice, we carry out a case study using an Italian recent survey asking the opinion of university students about different subjects, such as interreligious dialog, women/religion relationship, religion/death relationship, homosexuality, and multicultural society.

Published: July 2020

Abstract
Software testing is a very important technique to design the faultless software and takes approximately 60% of resources for the software development. It is the process of executing a program or application to detect the software bugs. In software development life cycle, the testing phase takes around 60% of cost and time. Test case generation is a method to identify the test data and satisfy the software testing criteria. Test case generation is a vital concept used in software testing, that can be derived from the user requirements specification. An automatic test case technique determines automatically where the test cases or test data generates utilizing search based optimization method. In this paper, Cuckoo Search and Bee Colony Algorithm (CSBCA) method is used for optimization of test cases and generation of path convergence within minimal execution time. The performance of the proposed CSBCA was compared with the performance of existing methods such as Particle Swarm Optimization (PSO), Cuckoo Search (CS), Bee Colony Algorithm (BCA), and Firefly Algorithm (FA).

Abstract
Tera hertz optical asymmetric demultiplexer (TOAD) using two semiconductor optical amplifiers and two control signals has been used to design an all optical parity checker and generator. The same circuit can generate and check both even and odd parity using a control input. The numerical simulation using Matlab 2007b is done for performance analysis of the proposed device in terms of output bit pattern, amplified spontaneous emission (ASE) noise, extinction ratio, contrast ratio, pseudo eye diagram, relative eye opening (98.9% for 20 dB gain and 96.21% for 10 dB gain) and their variation with input control pulse energy, amplified spontaneous emission noise factor for different unsaturated gain. The simulated value of E.R. = 81.39 dB, C.R. = 83.15 dB, REOP = 98.9% and Q value = 86.16 dB are found for this proposal.

Published: July 2020

Abstract
This work is focused to carry out the investigation of wavelength division multiplexing (WDM) approach on free space optical (FSO) transmission systems using Erbium Ytterbium Doped Waveguide Amplifier (EYDWA) integrated as post-or pre-amplifier for extending the reach to 30 Km for the cost-effective implementation of FSO system considering weather conditions. Furthermore, the performance of proposed FSO-wavelength division multiplexing (WDM) system is also evaluated on the effect of varying the FSO range and results are reported in terms of Q factor, BER, and eye diagrams. It has been found that, under clear rain the post-amplification was performed and was able to reach transmission distance over 27 Km, whereas, the FSO distance has been limited at 19.5 Km by using pre-amplification.
