An iterative process for a finite family of Bregman totally quasi-asymptotically nonexpansive mappings and a system of generalized mixed equilibrium problems in reflexive Banach spaces
Authors: Nguyen Trung Hieu
Published: January 2022

The equilibrium problem and its generalizations had a great influence in the development of some branches of pure and applied sciences. The equilibrium problems theory provides a natural and novel approach for some problems arising in nonlinear analysis, physics and engineering, image reconstruction, economics, finance, game theory and optimization. In recent times, there were many methods in order to solve the equilibrium problem and its generalizations. Some authors proposed many iterative methods and studied the convergence of such iterative methods for equilibrium problems and nonexpansive mappings in the setting of Hilbert spaces and Banach spaces. Note that a generalized mixed equilibrium problem is a generalization of an equilibrium problem and a Bregman totally quasi-asymptotically nonexpansive mapping is a generalization of a nonexpansive mapping in reflexive Banach spaces. The purpose of this paper is to combine the parallel method with the Bregman distance and the Bregman projection in order to introduce a new parallel hybrid iterative process which is to find common solutions of a finite family of Bregman totally quasi-asymptotically nonexpansive mappings and a system of generalized mixed equilibrium problems. After that, we prove that the proposed iteration strongly converges to the Bregman projection of initial element on the intersection of common fixed point set of a finite family of Bregman totally quasi-asymptotically nonexpansive mappings and the solution set of a system of generalized mixed equilibrium problems in reflexive Banach spaces. As application, we obatin some strong convergence results for a Bregman totally quasi-asymptotically nonexpansive mapping and a generalized mixed equilibrium problem in reflexive Banach spaces. These results are extensions and improvements to the main results in [7, 8]. In addition, a numerical example is provided to illustrate for the obtained result.

Merely providing the formula of area in the learning activity can impede students’ deep understanding of the concept of area. This study was a qualitative design research that aimed to develop a learning design by using the context of pixel art and grid paper to build students' knowledge of the concept of area measurement. There were three stages in this study, namely, preparation, teaching experiment, and retrospective analysis. The subjects of this study were 25 students of P3 (Primary 3) SD Global Inbyra School. However, the discussion focused on a group consisting of three students. The research subjects were given a mini lesson consisting of 2 meetings. It can be seen from the first meeting that the pixel art drawn by the students built on their initial measuring ability because they automatically notice that half square and half square make up 1 square. At the second meeting, students demonstrated their ability to estimate the number of squares (area) in an irregular picture. In the activity of making any shapes that have an area of 20 square units, students were aware that to find the area of the rectangle, they can use repeated addition which can be directed to the area of the rectangle (p x l).

Published: January 2022

Many new learning models in the 21st century have emerged in improving students' academic skills, one of which is research-based learning (RBL). This pedagogic and constructivist model connects research and learning in improving students' critical thinking skills (CTS). The results of the study show that studies in empowering students' CTS using RBL are still limited. Therefore, exploration and deeper measurement of CTS with the RBL model were carried out through this study. The purpose of this study was to improve students' CTS using the RBL learning model. The results of the ANCOVA test showed that there was an effect of the RBL model in improving students' CTS. Descriptive data also shows that the average value of CTS is 72.70 using RBL, while students who take part in learning using conventional models show an average value of critical thinking skills of 58.30. Thus, RBL can be recommended in increasing the CTS of elementary school students in science learning.

Abe Road: Kuwata Keisuke’s Beatles Parody
Authors: Manabe Noriko
Published: January 2022

In May 2009, when the Japanese LDP government was in a weakened position, Kuwata Keisuke, lead singer of popular rock band Southern All Stars, performed a parody of the Beatles’ Abbey Road on his weekly television show. Backed by a band performing an uncanny cover of the album, he rewrote the lyrics into commentary on corruption in Japanese politics, fiscal problems, the death penalty, and other political issues.

This performance was highly unusual: Japanese recording artists rarely engage in politics. The recording and broadcast industries disallow lyrics on controversial topics, and management discourages artists from engaging in politics. Kuwata staged his rebellious gesture as a “mishearing” of a well-known album.

Kuwata transformed Abbey Road into political parody through linguistic sleight of hand. Kuwata chose Japanese lyrics with similar vowels and consonants (as demonstrated by their proximities on the International Phonetic Alphabet) to make them sound like the original English lyrics. By presenting his acrid commentary as a parody of this much-loved album and thus framing it as humorous entertainment, Kuwata was able to publicly criticize Japanese politicians.

The development of television technologies and the need to transmit high-quality video information requires that modern digital television and broadcasting systems can transmit large amounts of information. The use of signals with multi-position amplitude and phase-shift keying 16-APSK and 32-APSK in DVB-S2 generation satellite television systems made it possible to transmit 30% more data in the same frequency bands compared to the previous DVB-S standard. The latest DVB-S2X digital satellite TV standard is an extension of the DVB-S2 standard and supports modulations of 64,128,256-APSK. It is known that increasing the positionality of signals reduces the noise immunity of their reception and the system as a whole. In addition, the presence of non-fluctuation interference in the radio channel that falls into the frequency band of the useful signal has a strong influence on noise immunity. The article uses statistical radio engineering methods to calculate the probability of a bit error when receiving M-APSK signals against the background of phase-shift keying interference at different parameters of the latter. It is shown that of phase-shift keying interference of even low intensity (µ < 0.3) falling into the main lobe of the signal spectrum significantly reduces the noise immunity of receiving 16-APSK and 32-APSK signals. High-intensity interference (µ ≥ 0.5) practically destroys reception. The influence of phase-shift keying interference decreases with an increase in its detuning relative to the carrier frequency of the useful signal and an increase in the relative transmission rate of the interference. A comparison of the reception quality when using M-PSK, M-QAM and M-APSK signals is carried out and it is shown that the noise immunity of receiving M-QAM and M-APSK against the background of phase-shift keying interference is approximately the same. M-PSK signals are significantly inferior to them in terms of reception noise immunity.

The results of the numerical solution of the problem of propagation of an electromagnetic video pulse signal of nanosecond duration in a dissipative medium are presented for use in the deep georadar data interpretation. Based on the developed scheme for integrating Maxwell's equations, the results of numerical modeling of the propagation of electromagnetic pulses of various shapes without approximations, usually used in the traditional solution of GPR problems, including the separation of temporal and spatial variables of the electromagnetic field and neglect of the rapid field change in comparison with the processes occurring in the medium, are obtained. The influence of the pulse shape on the shape of the electromagnetic echo signal is considered for various models of the medium close to real conditions, including those with a gradient change in electrical conductivity and permittivity. The influence of the distribution of electrical conductivity of the medium is studied.

Chromatography is a term that refers to a group of laboratory techniques for separating mixtures. Chromatography works on the premise of solute partitioning between two phases or solvents. The technique of paper chromatography is commonly used to separate plant pigments based on their molecular weight. Plant pigments include chlorophyll-b, chlorophyll-a, carotenoid, and xanthophyll, which all have various molecular weights, colours, and absorption maxima. In this study, an attempt was made to see how a new solvent (Akshya-Swagatika solvent) can be used to separate plant pigments using paper chromatography, as well as a new detection method developed by us known as Mobile chromatogram detection system (MCDS) that can be used for compound identification and photographing. As shown in the table and photograph, pigments are separated by molecular weight and band colour, with carotenoid having the highest RF value and chlorophyll-b having the lowest. It was obvious that the Akshya-Swagatika solution could be used to separate plant pigments in paper chromatography. Photograph taken with a mobile chromatogram detection system that is much clearer than normal one. In developing countries, both solvent and detection systems are useful in explaining paper chromatography in a cost-effective manner. The MCDS detection system is cost-effective fast method which replaces traditional sophisticated detection procedures.

Rhizosphere, phylloplane and caulosphere is the region where a complex community of microbes, mainly bacteria and fungi are present. The microbe- plant interaction in these regions can be beneficial, neutral, variable, or deleterious for plant growth. The bacteria that exert beneficial effects on plant development are termed plant growth promoting bacteria. To isolate the bacteria from rhizosphere, phylloplane and caulosphere of brinjal (Solanum melongena L.). The seeds of 16 cultivars of brinjal (Solanum melongena L.) viz., Arka keshav, Arka shirish, Arka kusumaker, and IIHR accession numbers 389,386,387,377 Tc, BB44, 391, 433, 434, 427, 447, 448, 476 and 487 that were used in the initial screening experiment were obtained from the Department of Vegetable crops, IIHR, Hessaraghatta, Bangalore. Brinjal (Solanum melongena L.) plants of different varieties were collected from seven locations around Bangalore viz., Hessaraghatta, Yelahanka, Kengeri, Madi vala, Hebbal, Tirumalapura and Attibele were also screened for the presence of associative bacteria. Associative microorganisms isolated from the rhizosphere, phylloplane and shoot regions of brinjal (Solanum melongena L.), revealed the presence of three morphologically different colonies. 80% of 16 cultivars of the brinjal (Solanum melongena L.) screened showed the presence of associative bacterial colonies. In this study diazotrophic BBI were obtained from the rhizoplane, phylloplane and stem of 16 cultivars of brinjal (Solanum melongena L.) that were screened. The dominant pearl-colored colonies isolated from all varieties of brinjal plants that were screened was identified and showed maximum nitrogen fixing ability compared with that of the other colonies. The phylloplane of brinjal (Solanum melongena L.) plants from seven different locations around Bangalore showed the presence of the dominant pearl-colored colonies.  Moderate growth of bacteria was observed in root, stem and leaf bits sterilized up to 35 minutes. Even on surface sterilized roots which were homogenized and inoculated on growth media, dense growth of bacteria was observed there by establishing the presence of bacteria inside the root system. For the first time the presence of growth promoting bacteria on the rhizosphere and endorhizosphere of brinjal (Solanum Melongena L.) cultivars was established.

Application of chemical fertilizer is an integral practice to optimize crop productivity, but the dominant use of chemical fertilizers contributes largely to the deterioration of the environment, leads to loss of soil fertility, increases pollution, and causes hazardous diseases. Hence, the chemical fertilizers, pesticides and other supplements are being replaced by the plant growth promoting bacteria (PGPB) due to their improved potency and environment friendly nature. Plant growth-promoting bacteria (PGPB) can enhance plant growth by a wide variety of mechanisms like Phosphate (P) solubilization, Potassium solubilisation, siderophore production, biological nitrogen fixation and Indole acetic acid (IAA) production. The Klebsiella species is also known to exhibit important PGP traits like solubilization of phosphate, phytohormone production and good germination potential. In present study the Klebsiella pneumoniae PNE1 was selected from the isolates obtained from vegetable waste collected from Kadi market. The isolate was selected on the basis of its ability for Nitogen fixation, Phosphate solubilization, Potassium solubilization, IAA production, EPS production and biopolymer degradation. The molecular identification through 16S rRNA gene sequence, confirmed the isolate as Klebsiella pneumonia PNE1. Quantitative analysis of ammonia production revealed that isolate Klebsiella pneumonia PNE1 produced 0.5 µg/ml of ammonia (NH3) on 6th day of incubation and produced 0.09 µg/ml Nitrite after 8th day of incubation. The Phosphate solubilisation Index (SI) of the isolate was 4.16 and the isolate released 177.50 μg/ml Phosphate. The qualitative estimation of Potassium solubilisation by the isolate Klebsiella pneumoniae PNE1 in terms of Potassium solubilisation zone was found to increase gradually from day 1 to 7 days and was maximum at 2nd day with a KSI of 3.6. The isolate Klebsiella pneumoniae PNE1 released 29.94 mg/l Potassium on 21th day of incubation respectively. The IAA production was found to be 94.96 µg/ml. The maximum the EPS yield was 11.3 mg/ml. The Klebsiella pneumonia PNE1 had capacity to degrade Cellulose, Pectin and Xylan i.e. all biopolymers tested. The antibiotic susceptibility test indicated that isolate was sensitive to all 22 antibiotics tested. The Klebsiella pneumonia PNE1 thus, shows important plant growth promoting traits and can be used in a bio-fertilizer formulation for sustainable agriculture.

Results: Group narrative therapy significantly improved reported sexual function (F = 40.90; p = .001) and decreased couple burnout (F = 59.03; p = .001) in women with skin cancer. Conclusions: Narrative therapy seems to effectively improve sexual function and couple burnout in women with skin cancer.

Serendipity: an interesting word
Authors: Nguyen Minh-Hoang
Published: January 2022

Recently, I had a chance to work on a project about the serendipity concept using the Mindsponge information processing and 3D creativity making frameworks. Personally, I think that serendipity is an interesting word due to not only its intrinsic values but also discoveries and ideas related to serendipitous moments that I can observe around me.
Individual’s perceivable range and the notion of unexpectedness
Authors: Nguyen Minh-Hoang
Published: January 2022

Unexpectedness is a person’s subjective perceptions of a certain event but not entirely the objective existence of the event itself. The unexpected moment happens when a person subjectively expects it not to happen as it does or when a person first perceives novel information to which they have no reference in mind. Therefore, there can be two circumstances: 1) unexpectedness from within the perceivable range, and 2) unexpectedness from beyond the perceivable range.
Can lifestyle factors be the key in deciding the COVID-19 outcome?
Authors: Angarai Ramakrishnan , Sharma Kanishka , Gangadhar B. N.
Published: January 2022

The COVID-19 recovery rate of 97.3% and the death per million of 345 in India are better than the corresponding values in the USA and most of Europe despite better health infrastructure in these countries. The mean COVID fatality rate of Europe and a few countries in America is seven times that of India. This warrants a systematic study of the factors behind this conspicuous disparity. It is time to study lifestyle and other factors that may be related to recovery with minimal medical intervention or serious complications, leading to belated recovery and sometimes mortality. Obesity and excessive consumption of soft drinks, red meat and processed food may have a role to play in the European and American countries. On the other hand, the use of turmeric, black pepper, ginger in daily cooking, consumption of Indian gooseberry, Tulasi, different decoctions (Kashaya) and practice of various immune-boosting breathing exercises including yoga might have had a role in India. A detailed study involving a sizable number of cases of recovery and death in India, USA and some European countries will throw light on these factors behind the significant differences. The results shall provide crucial learning to the world for managing future waves and pandemics.

‘Trust Us’: Open Data and Preregistration in Political Science and International Relations
Authors: Scoggins Bermond , Robertson Matthew Peter
Published: January 2022

The scientific method is predicated on transparency -- yet the pace at which transparent research practices are being adopted by the scientific community is slow. The replication crisis in psychology showed that published findings employing statistical inference are threatened by undetected errors, data manipulation, and data falsification. To mitigate these problems and bolster research credibility, open data and preregistration have increasingly been adopted in the natural and social sciences. While many political science and international relations journals have committed to implementing these reforms, the extent of open science practices is unknown. We bring large-scale text analysis and machine learning classifiers to bear on the question. Using population-level data -- 93,931 articles across the top 160 political science and IR journals between 2010 and 2021 -- we find that approximately 21% of all statistical inference papers have open data, and 5% of all experiments are preregistered. Despite this shortfall, the example of leading journals in the field shows that change is feasible and can be effected quickly.
"They Are Such an Asshole": Describing the Targets of a Common Insult Among English-Speakers in the United States
Authors: Sharpe Brinkley M. , Hyatt Courtland , Lynam Donald , Miller Josh
Published: January 2022

Insults convey information about the speaker’s perception of the target’s personality. Previous research has found that several commonly used insults (“asshole,” “dick,” “bitch”) are uniformly associated with self- and other-reported antagonism (or low Agreeableness). We aimed to replicate and extend these findings by focusing on the insult “asshole,” a common insult used to refer to both men and women. In the present study, participants (n = 397) described the “biggest assholes” in their lives using a measure of the Five-Factor Model of personality. “Assholes” described by participants were typically middle-aged, predominantly male, and included romantic partners, coworkers, bosses, family members, and friends. Results showed that “assholes” were perceived to be characterized by interpersonally relevant traits (i.e., low Agreeableness, high Anger). The consensus Five Factor Model profile for target “assholes” was similar to expert profiles of psychopathic, antisocial, and narcissistic personality disorders. Exploratory analyses conducted on open-ended descriptions of nominated bothersome “asshole-related” behaviors revealed common themes including manipulation, aggression, irresponsibility, and entitlement.
Which moral exemplars inspire prosociality?
Authors: Han Hyemin , Workman Clifford Ian , May Joshua , Scholtens Payton , Dawson Kelsie J , Glenn Andrea , Meindl Peter
Published: January 2022

Some stories of moral exemplars motivate us to emulate their admirable attitudes and behaviors, but why do some exemplars motivate us more than others? We systematically studied how motivation to emulate is influenced by the similarity between a reader and an exemplar in social or cultural background (Relatability) and how personally costly or demanding the exemplar’s actions are (Attainability). Study 1 found that university students reported more inspiration and related feelings after reading true stories about the good deeds of a recent fellow alum, compared to a famous moral exemplar from decades past. Study 2A developed a battery of short moral exemplar stories that more systematically varied Relatability and Attainability, along with a set of non-moral exemplar stories for comparison. Studies 2B and 2C examined the path from the story type to relatively low stakes altruism (donating to charity and intentions to volunteer) through perceived attainability and relatability, as well as elevation and pleasantness. Together, our studies suggest that it is primarily the relatability of the moral exemplars, not the attainability of their actions, that inspires more prosocial motivation, at least regarding acts that help others at a relatively low cost to oneself.
Innocent cheaters: a new scale measuring the moral disengagement of marital infidelity
Authors: Lișman Carmen , HOLMAN ANDREI CORNELIU
Published: January 2022

Marital infidelity is both socially perceived as immoral and very frequent. This contradiction might be explained through the process of moral disengagement, specifically by the use of certain socially shared moral justifications of infidelity, which consequently foster unfaithful behavior. This research developed and examined the Infidelity Moral Disengagement Scale (IMDS), aiming to capture the strategies of morally legitimizing infidelity used among people engaged in marital relationships. Across two studies (total N = 609 married participants) we investigated the dimensions and psychometric properties of the IMDS. Results showed that the dominant strategies of legitimizing marital infidelity are the diffusion of responsibility, the attribution of blame on the cheated partner, advantageous comparisons with other immoral acts, justifying infidelity through certain benefits, and minimizing its negative consequences. The IMDS emerged as negatively related to moral identity and strongly associated to people’s past infidelity and to their tendency to engage in unfaithful behaviors.
Understanding Reward Dysfunction in Bipolar Affective Disorder through Behavioural, Cognitive and Neurobiological Changes
Authors: Wyatt Caroline
Published: January 2022

Bipolar disorder, like many neuropsychiatric conditions, can be studied from a number of perspectives; from observation of behaviour, to study of cognitive dysfunction, through to changes at the molecular and genetic level. A consequence of this way of working is that there is inadequate communication between different levels of analysis, such that insufficient thought is given to whether a theoretical model derived from behavioural work fits with neurobiological data, and vice versa. Such limitations represent a key limiting factor in successful translation. Therefore, this paper takes a dominant theoretical model of bipolar disorder, based on that by Gray (1994) and developed by Alloy et al., (2015) as a basis to propose that the foundational pathology in bipolar is reward hypersensitivity, and to review how recent diverse neurobiological, cognitive and behavioural findings fit with this understanding. Executive Function deficits, partially derived from heritable structural changes are suggested as a foundation through which reward hypersensitivity develops to disorder, and CANA1C polymorphism-induced hyperactivity, further serves to drive the system towards reward seeking goals, through interaction with dopaminergic systems. This action is supplemented by a genetic predisposition for cognitive regulatory dysfunction, leading to improper modulation of emotive and reward networks. Specifically, deficits in top-down limbic modulation leads to behaviours disproportionally driven by limbic and reward circuitry; this pathology strengths over time through use. This therefore eventually results in substantial regional disconnect, reflected in epigenetic changes to neurotransmitters and observable histological changes.
