Gratitude is morally sensitive
Authors: Yu Hongbo , Zhou Yubo , Nussberger Anne-Marie
Published: March 2022

Helping acts, however well-intended and beneficial, sometimes involve immoral means or immoral helpers. Here we explore whether help recipients consider moral evaluations in their appraisals of gratitude; a possibility that has been neglected by existing accounts of gratitude. Participants felt less grateful and more uneasy when offered immoral help (Study 1, N = 150), and when offered morally neutral help by an immoral helper (Study 2, N = 172). In response to immoral help or helpers, participants were less likely to accept the help and less willing to strengthen their relationship with the helper even when they accepted it. Study 3 (N = 276) showed that recipients who felt grateful when offered immoral help were perceived as less likable, less moral, and less suitable as close relationship partners than those who felt uneasy by observers. Our results demonstrate that gratitude is morally sensitive and suggest this might be socially adaptive.
Psychopathy and Associations with Reward Responsiveness and Social Networks in Emerging Adults
Authors: Ploe Montana , Berluti Kathryn , Ibonie Stevi , Villanueva Cynthia , Marsh Abigail , Gruber June
Published: March 2022

Psychopathic traits vary continuously within the general population and are characterized by bold, callous, and disinhibited personality features. Research in psychopathy primarily focuses on associations with various negatively-valenced social and affective constructs, but less work has investigated the relationship between psychopathy and positively-valenced constructs. The present investigation examined self-reported psychopathy and associations with reward responsiveness and self-reported social networks among first-year university students (N = 245). Results indicated that the triarchic psychopathy facets uniquely mapped onto two different domains of reward; specifically, boldness predicted increased reward responsiveness whereas disinhibition predicted increased delay discounting. With respect to social networks, boldness predicted increased, and meanness predicted decreased, self-reported quantity and quality of peer relationships. No other subscales of psychopathy significantly predicted either facet of reward or social networks. These findings provide insight on reward-relevant models of psychopathy as well as the socially maladaptive, as well as adaptive, facets of psychopathy during emerging adulthood. This study further promotes the benefits to understanding the multidimensional nature of psychopathy and the triarchic model.
Nothing to rescue: If cognitive load is not sufficient to affect cardiovascular dynamics, resonance paced breathing cannot facilitate performance.
Authors: Leganes-Fonteneau Mateo , Bates Marsha , Muzumdar Neel , Buckman Jennifer
Published: March 2022

The cardiovascular system offers a window to the physiological adaptations generated by cognitive stress. Importantly, it is possible to modulate the cardiovascular system via resonance breathing techniques, and this has shown to improve cognitive performance. However, there is a lack of research on the mechanisms by which resonance breathing enacts its effects on cognitive processing, and this research can spur the development of novel clinical tools. In this brief report we examined the effect of cognitive load on heart-rate variability (HRV) in the high-frequency (HF) range and at 0.1Hz, as a proxy for baroreflex activation. Participants (n=65) completed a 0-back task, followed by a control breathing task, and a 2-back task. Finally they completed a resonance paced breathing task and another 2-back task (order of breathing tasks counterbalanced). We also obtained subjective measures of stress and difficulty after each n-back task. Contrary to our hypotheses, we found a sensitively null effect of 2-back on 0.1Hz and HF HRV. Further, resonance breathing did not improve physiological state during subsequent 2-back task, nor did it improve cognitive performance or decreased perceived stress and difficulty. These results fail to replicate, in a healthy population, previous findings regarding the impact of increased working memory load on HRV. Null results are discussed within novel predictive coding perspectives of the role of HRV in cognitive adaptations and mental health, and can help guide future research on the effect of resonance breathing in cognitive processing.
Do people know when they are good at spotting liars? – Metacognitive efficiency in Lie Detection
Authors: Said Nadia , Volz Sarah , Reinhard Marc-André , Müller Patrick , Huff Markus
Published: March 2022

We investigated whether the confidence in lie detection judgments is a signal for the accuracy of judgments. We argue that previous methods in tackling this question are inadequate as the assessment of judgment accuracy and confidence is confounded with response bias and lie detection performance. We addressed this confidence-accuracy puzzle by applying a hierarchical Bayesian approach based on Signal-Detection Theory to estimate metacognitive efficiency.Metacognitive efficiency describes individuals' insight into the accuracy of their judgments about truth and deception, but unlike previous measures, it is free of bias and independent of lie detection performance. In re-analyses of 12 studies (N=2817 participants in total), metacognitive efficiency was on average only about 23% of what would have been expected given participants’ discrimination performance. Hence, individuals largely lack metacognitive insight into the quality of their judgments, which is particularly problematic because they cannot reliably discriminate between lies and truths.
Dissipation of Reactive Inhibition is Sufficient to Explain Post-rest Improvements in Motor Sequence Learning.
Authors: Gupta Mohan , Rickard Timothy Charles
Published: March 2022

The prevailing hypothesis for observed post-rest motor reaction time improvements is offline consolidation. In the present study, we present evidence for an alternate account involving the accrual and dissipation of reactive inhibition. Four groups of participants (N=159) performed a finger tapping task involving either massed (30 s per trial) or spaced (10 s per trial) training, and with one of two break intervals between each trial: 10 s or 30 s. After 360 s of training in each group, there was a 300 s rest period followed by a final test on the same task. The results show that the smaller the ratio of break time to on-task trial time during training, the larger the improvement in reaction time after the rest period. Those results are fully consistent with a model that assumes no facilitating offline consolidation, but rather learning that is concurrent with performance and reactive inhibition that builds during performance and dissipates during breaks.
Evaluating global interest in biodiversity and conservation
Authors: de Oliveira Caetano Gabriel Henrique , vardi Reut , Jarić Ivan , Correia Ricardo A. , Roll Uri , Veríssimo Diogo
Published: March 2022

The first target of the Convention for Biological Diversity (Aichi target 1) was to increase public awareness towards the values of biodiversity and actions needed to conserve it - a key prerequisite for other conservation targets. Nevertheless, monitoring success in achieving this target at a global scale is difficult. However, the increased digitization of human life in recent decades offers an insight in people’s interests at an unprecedented scale, which allows a more comprehensive evaluation of success towards Aichi target 1 than previously attempted. Here, we used Google search volume data to evaluate global interest in biodiversity and its conservation, and investigated their correlates across countries. We found that during 2013-2020 global searches for biodiversity increased, driven mostly by searches for charismatic fauna. However, searches for conservation actions, driven mostly by searches for national parks, decreased since 2019 likely due to the COVID-19 pandemic. We further found that economic inequality was negatively correlated with interest in biodiversity and conservation, while purchasing power was indirectly positively correlated through increased education and research. Our results suggest partial success towards achieving Aichi target 1, in that interest in biodiversity has increased widely, but not for conservation. We suggest that increased outreach and education efforts towards neglected aspects of biodiversity and conservation are still needed. Popular topics in biodiversity and conservation could be leveraged to increase awareness of other topics, with attention to local socioeconomic contexts.

Published: March 2022

The results of a research program conducted at the University of Mustansiriayah in Iraq to analyze the qualities of concrete created with crushed bricks and crush concrete are presented in this paper. To make a suitable aggregate, these materials were crushed. Some aggregates were treated, while others were not. The properties investigated were the workability and the density of fresh the aggregates of crushed bricks and crush concrete were treated in some mixtures and others were not treated. The properties investigated were the workability and the density of fresh concrete, and the compressive strength and tensile splitting strength behavior of hardened concrete. Different replacement ratios (0, 50%, and 100%) were investigated. The concrete rustles produced with recycled aggregates were compared with a reference concrete produced with natural coarse aggregates currently used in Iraq. Using surface treatment with silicate solution, when comparison to RCA50 and RCA100 samples, TRCA50 and TRCA100 compressive strength improved by roughly 5.05 percent and 5.9 percent after 28 days, respectively. And came closer to concrete with natural aggregate R, and improved 3.25% and 4.6% in TBR100 and TBR50, respectively compared. With the BR100 and BR50 respectively, they added a cross resistance of R for TRAC100% when silica fume was added, approaching R at TBR100%. Aggregates indicate that this type of concrete can be used in various precast applications.

Authors: M. Atiyah Mustafa , Jafer Mahdi Ali , A. Al-Anbarri Kassim
Published: March 2022

This paper proposed the integration of the wind energy system (WES) with the grid consists of a wind turbine, a permanent magnet synchronous generator (PMSG), a switch-mode rectifier (SMR) and a three-phase voltage source inverter (VSI). Optimal torque control (OTC) method is applied to the converter on the generator side for maximizing the power coefficient under the change in wind speeds. To synchronize the WES with the grid, another controller is applied to keep dc-bus voltage at constant value and to regulate active and reactive power transmitted into a grid. A system of WES connected into a grid is created and tested in the MATLAB/SIMULINK platform version 2019b. Comprehensive simulation results are used to analyze and verify the excellent performance of the suggested two- control strategy on the machine and grid side.

Published: March 2022

According to data from BPS Kabupaten Jember, the amount of cucumber production fluctuated from 2013 to 2017. Some literature also mentions that one of the causes of the amount of cucumber production is disease attacks on these plants. Most of the cucumber plant diseases found in the leaf area such as downy mildew and powdery mildew which are both caused by fungi (fungal diseases). So far, farmers check cucumber plant diseases manually, so there is a lack of accuracy in determining cucumber plant diseases. To help farmers, a computer vision system that is able to identify cucumber diseases automatically will have an impact on the speed and accuracy of handling cucumber plant diseases. This research used 90 training data consisting of 30 healthy leaf data, 30 powdery mildew leaf data and 30 downy mildew leaf data. while for the test data as many as 30 data consisting of 10 data in each class. To get suitable parameters, a feature selection process is carried out on color features and texture features so that suitable parameters are obtained, namely: red color features, texture features consisting of contrast, Inverse Different Moment (IDM) and correlation. The K-Nearest Neighbor classification method is able to classify diseases on cucumber leaves (Cucumis sativa L.) with a training accuracy of 90% and a test accuracy of 76.67% using a variation of the value of K = 7.
Genetic Algorithm Optimization on Nave Bayes for Airline Customer Satisfaction Classification
Authors: Religia Yoga , Maulana Donny
Published: March 2022

Airline companies need to provide satisfactory service quality so that people do not switch to using other airlines. The way that can be used to determine customer satisfaction is to use data mining techniques. Currently, the website www.kaggle.com has provided Airline Passenger Satisfaction data consisting of 22 attributes, 1 label and 25976 instances which are included in the supervised learning data category. Based on several previous studies, the Naïve Bayes algorithm can provide better classification performance than other classification algorithms. Several studies also state that the use of Naive Bayes can be optimized using Genetic Algorithm (GA) to obtain better performance. The use of Genetic Algorithm for Nave Bayes optimization in classifying Airline Passenger Satisfaction data requires further research to ensure the performance of the given classification. This study aims to compare the use of the Naive Bayes algorithm for the classification of Airline Passenger Satisfaction with and without GA optimization. The data validation process used in this study is to use split validation to divide the dataset into 95% training data and 5% testing data. The test results show that the use of GA on Naive Bayes can improve the classification performance of Airline Passenger Satisfaction data in terms of accuracy and recall with an accuracy value of 85.99% and a recall of 87.91%.

Published: March 2022

The selection of prospective customers who apply for credit in the banking world is a very important thing to be considered by the marketing department in order to avoid non-performing loans. The website www.kaggle.com currently provides South German Credit data in the form of supervised learning data. The use of data mining techniques makes it possible to find hidden patterns contained in large data sets, one of which is using classification modeling. This study aims to compare the classification of South German Credit data using the Naïve Bayes algorithm and compare the classification of South German Credit data using the Naïve Bayes algorithm with particle swarm optimization (PSO). The test was carried out using a confusion matrix to determine the accuracy, precision and recall values of the research model. Based on the test, it is known that PSO is able to increase the accuracy and recall of Nave Bayes, but PSO has not been able to increase the precision value of Nave Bayes. The test results show that PSO optimization gives Naïve Bayes an increase in the value of accuracy by 0.46%, and gives Naïve Bayes an increase in recall value by 3.02%.

Authors: Tran Henry , Jenkins Zach
Published: March 2022

The COVID-19 pandemic, recent awakening of society to its enduring racial pandemic, rising expectations for employer accountability, and an increasingly diverse populace jointly indicate that times are changing for the future of education work. Yet the approach to human resource management (HRM) employed in schools has been criticized for being outdated, and even the “reform” model from the accountability era has been based on debunked and antiquated models. This article synthesizes the literature to summarize talent-centered education leadership (TCEL) and its seven core principles. TCEL is a new education HRM model that promotes inclusivity and humanization of the education workplace and has been suggested as a framework to aid education employers with embracing the future of education work.

Published: March 2022

Os estudos da memória despertam o interesse das mais variadas ciências, sendo que no campo da comunicação as investigações se voltam ao uso estratégico da memória de empresa na construção e manutenção da identidade corporativa, e também os seus reflexos na imagem e reputação organizacional. O discurso memorialístico, porém, é impregnado de silêncios e esquecimentos que, conscientes ou não, também dão pistas sobre as organizações e têm valor de mensagem na comunicação. Este ensaio, portanto, tem como objetivo transcender a observação das práticas de comunicação da memória institucional1, pautadas em sua grande maioria apenas em lembranças, e explora as nuances do esquecimento, dos silêncios que envolvem a seleção do que recuperar ou preservar. Nesse sentido, apontamos para novas direções de pesquisa envolvendo a temática, num esforço constante de avançar nas perspectivas de uso da memória pelas empresas. 1No decorrer da nossa pesquisa e conforme a bibliografia consultada, encontramos a utilização dos termos memória institucional, memória organizacional, memória empresarial e memória corporativa. Embora existam diferenças conceituais apontadas por alguns pesquisadores, neste texto empregamos as denominações como sinônimos, respeitando a escrita do autor de referência e a fluidez da escrita.

Published: March 2022

In this paper, we have studied the role of chromosomal abnormalities in the expression of small nucleolar RNAs (snoRNAs) of radioresistant (K562) and radiosensitive (HL-60) leukemia cell line. Cells were exposed to an X-ray dose of 4 Gy. SnoRNA expression was investigated using NGS sequencing. The distribution of expressed snoRNAs on chromosomes has been found to be different for two cell lines. The most significant differences in the expression of snoRNAs were found in the K562 cell line based on the analysis of the dynamics of log2fc values. The type of clustering, the number and type of snoRNAs slightly differed in the chromosomes with trisomy and monosomy and had a pronounced difference in pairs with marker chromosomes in both cell lines. In this study, we have demonstrated that chromosomal abnormalities alter the expression of snoRNA after irradiation. Trisomies and monosomies do not have such a noticeable effect on the expression of snoRNAs as the presence of marker chromosomes.

Published: March 2022

Oil and gas are the resource buried in deep underground. The purpose of petroleum exploration is to delineate the sand body saturated with the oil or gas. The thickness of sand is an important property of sand layer in the reservoir research. In the oilfield of Eastern China, the thickness of sand body is usually very thin and below ten meters, so it is very hard for us to estimate the real thickness of sand body because its thickness is far less than the resolution limit of seismic wavelet in exploration. For further discussion of the problem, we probed into how to use the method of amplitude versus offset (AVO) to predict the thickness of sand body in this paper. Firstly, a set of thin sand models with different thickness are made; then, the prestack gathers of the models are simulated with the reflectivity method; after that, AVO attributes of prestack gathers are analyzed; next, the relationship between AVO attributes and the thickness of thin sand are established; finally, the relationship is used for the prestack gathers of the entire seismic data, and the thickness of thin sand of study area are estimated.

Este trabalho tem por objetivo mostrar que devido às falhas no sistema aritmético, regras catedráticas pautadas em um equivocado padrão podem gerar resultados incorretos, tais como a regra da equação do segundo grau, que pode propagar uma falsa certeza de exatidão, pelo simples fato de se seguir paradigmas seculares, sem uma ampla observância contextual da realidade envolvida, pois ao tratarmos com ciências exatas, devemos sempre ter uma visão holística, considerando amplamente todos os fatores envolvidos, já que uma ação presente tem consequências no futuro e ao fundamentar-nos em sistemas falhos, acabamos tendo uma falsa sensação de acerto, já que seguimos todos pseudos preceitos à risca. No entanto um novo sistema surge, colocando a prova a contundência do caminho aritmético a ser seguido.

The COVID-19 pandemic is a pervasive problem that has affected all
segments of endeavour, especially in the social welfare system. Consequently,
the high risk of COVID-19 infections of the users of homes for the elderly and
infirm and employees is known. The aim of this paper is to point out the
importance and role of employees in homes for the elderly and infirm during the
COVID-19 pandemic. Therefore, this paper highlights the dangers, threats or
challenges faced by employees in homes for the elderly and infirm since they
are directly and daily in communication and interaction with the most at-risk
group. Furthermore, the paper points to the need for support systems in which
interpersonal communication with employees is necessary in order to preserve
work activity. The authors present the results of a survey conducted on a
sample of 132 employees. The results show how much the communication process during the pandemic affects employees and their approach to work with the aim
of preserving their psychological state and thus the life quality of people
placed in homes for the elderly and infirm.

This paper aims to
determine the physical activity levels of younger school-age pupils concerning
gender. The study involved 190 third-grade pupils (98 male and 92 female) from
elementary schools in Čakovec. Physical activity was examined with the Fels
physical activity questionnaire for children (Treuth et al., 2005), used to
assess the physical activity level of children aged 7 to 19. Basic descriptive
parameters were calculated, and the Mann-Whitney U-test was applied to examine
differences in the TA level with respect to gender. The results showed that
66.3% of boys and only 34% of girls fall within the recommended daily physical
activity. Furthermore, significant differences were obtained in the field of ​​sports
(p = 0.00), ​​leisure time (p = 0.00), and total physical activity (p = 0.00).
Boys are significantly more active in sports, leisure time, and total physical
activity, while no significant difference between the genders was obtained in
the field of physical activity in housework. The research showed that the total
level of physical activity in this sample is very low in girls because only a
third meet the recommended daily physical activities. Therefore, promoting and
teaching physical activity is necessary at an early school age since entering
puberty significantly reduces physical activity in both genders.
An Analysis of Political Implications in Animal Farm from the Perspective of New Historicism
Authors: Xiao Shilin
Published: March 2022

George Orwell is a famous writer in the 20th century in England, especially known for his humanitarian spirit. Among his sharply written works, Animal Farm is of significant value to focus our attention on. This political allegory successfully creates a set of animal images, with some certain hidden meaning of political life. New Historicism offers readers another perspective to reorient into the context behind the text itself and reconsider the intertextuality between history and texts. Montrose proposes two concepts, “textuality of history” and “historicity of texts.” In the light of the two key concepts, this paper aims to take a descriptive approach to the political implications in Animal Farm with a focus on the close relationship between history and texts.

The situation of residential buildings in urban areas must be assessed to ascertain their form and age, functions, convenience, and liveability. As a result, this paper evaluates selected aspects of the condition of residential buildings in Akure, Nigeria. The study's objectives include examining the types of housing units, plot coverage, the number of rooms, and building setbacks. Other factors include housing tenure, the condition of the in-house tap, the type of toilet facilities, and the age of the buildings. The study drew on both primary and secondary data sources. A total of 1,369 people were polled, with 684, 480, and 205 representing the core, transition, and peripheral zones. According to the findings, tenement buildings accounted for 62.3 percent of Akure's residential buildings. In the city core, 88.6 percent of the respondents developed their lands above 50 percent, while 20.0 percent developed their lands above 50 percent on the outskirts. The paper suggests that the relevant stakeholders should enforce the subsisting building regulations, introduce environmental inspectors and mobile courts, and the Ondo State government should invest in urban infrastructure.

The body during normal metabolic function produces free radicals which are highly reactive species. Free radicals could also be introduced into the body from the environment. The oxidation induced by reactive oxygen species can result in DNA mutation, membrane protein damage and cell membrane disintegration. The present study assayed the preliminary phytochemicals, total phenolics and total flavonoids and free radicals scavenging ability of methanol extract of Jatropha tanjorensis leaf. Standard methods for determining phytochemicals, reducing power, nitric oxide scavenging, hydroxyl radical, and lipid peroxidation scavenging activity were employed.  The phytochemical screening result revealed the presences of phenols, flavonoids, saponin, alkaloids, tannins, terpernoids and steroids. The total phenolic content of methanol extract of Jatropha tanjorensis leaf measured by Folin-Ciocalteau reagent in terms of gallic acid equivalent was 11.35±0.82mgGAE/g. The flavonoid content of the plant sample calculated as Quercetin equivalent was 15.91±1.60mgQCE/g. GC-MS results revealed relevant pharmacological bioactive compounds. The antioxidative activity of the plant’s extract correlated with total phenolic content. The radical scavenging activity showed a dose dependent increase in the reducing power. The minimum NO inhibitory activity was 8.88±0.63 at 200µg/ml and the maximum activity was 32.70±2.71 at 800µg/ml. The minimum percentage H2O2 radical inhibitory activity was 8.30±0.88 at 200µg/ml and a maximum activity was 22.80±2.28 at 800µg/ml. There was also an increase scavenging effect of lipid peroxide radical in concentration dependent manner. The results of this study indicate that the leaf of Jatropha tanjorensis possess antioxidant properties and could serve as free radical inhibitor

Published: March 2022

Despite the dependable attempts by researchers in the field of sustainable fuels, engines, and emissions, there is a research gap in the area of variations of biodiesel blend ratios with specific fuel consumption of a compression ignition engine as well as the brake thermal efficiency of engines. Therefore, this article has investigated how the blending ratio of biodiesel from jatropha, neem and cotton seeds oil mixed with petrol diesel affects the brake specific fuel consumption of a compression ignition engine and likewise the brake thermal efficiency of the binary and multi-blends of biodiesel with diesel. Three different biodiesel samples were blended with diesel; the biodiesel was achieved through an alkali transesterification reaction. The blending was done for each biodiesel with diesel alone, and that of mixed biodiesel blends with fossil diesel in a definite ratio. The blends were run on a stationary four-cylinder compression ignition engine with an exhaust analyzer to detect CO, NOx, and exhaust temperature ranges. It was recorded that, the combustion of the blends at an engine speed of 1500 rpm, between the Jatropha blend ratios 25 to 30 %, the brake specific fuel consumptions (bsfc) decrease further as against the initial trend shown at 1000 rpm. At 2000 rpm engine speed, the Neem, as well as the mixed biodiesel blends, show entirely different patterns. 25% Jatropha blend gives the best overall performance
ANALYSIS OF LANDCOVER CHANGE AND ITS TRAJECTORY IN SUB-SAHARAN WEST AFRICA
Authors: Ibrahim Yahaya Zayyana , Sada Aisha
Published: March 2022

The study analysed land cover change and its trajectory in the study area using 300m CCI-land cover data for three epochs (2000, 2005 and 2010) respectively. Five sampling sites were selected and analysed land cover change trajectories. The findings show a continued decline in closed forest and sparse vegetation and increase in cropland; an indication of land degradation. This pattern of land cover change is accelerated by the increasing number of human populations which is estimated to be growing at the rate of 2-3% in Africa by the year 2100. This nature of population growth is expected to increase the size of croplands to support food security, which will exert more pressure on the ecosystem. However, the land cover trajectories presented in the five sampling points does not portray much changes. This can be attributed partly to the temporal extent of the study (15-years) and the spatial resolution of the data. Overall, the land cover change trajectories in the five sampling sites shows that the major changes in the land cover have been caused by human activities and to some extent natural climatic variations especially along the marginal areas, where the size of bare surface have increased. Therefore, there is a need to carry out a comprehensive land cover assessment at local level to ascertain the major local driving forces and biophysical drivers of land cover degradation in the study area
