“I don't just drink water for the sake of it”: Understanding the influence of value, reward, self-identity and early life on water drinking behaviour.
Authors: Rodger Amy , Papies Esther K.
Published: May 2021

The prevalence and negative health outcomes of underhydration call for a better understanding of water drinking motivations to inform interventions. This mixed methods study assessed the motivational processes underlying different patterns of water intake (i.e., high versus low) with a focus on the constructs like value, reward, self-identity and early life drinking habits. We used an initial quantitative survey (N = 400, M age = 24, N female = 293), followed by a qualitative survey (N = 101, M age = 33, N female = 75) in the general UK population. The quantitative survey assessed self-reported differences in water drinking behaviour (e.g., amount and frequency) in high and low water drinkers. The qualitative survey assessed underlying reasons for these differences, in a subset of participants. Participants who associated water drinking with valued, rewarding outcomes were more likely to drink a high and consistent amount of water, with less subjective effort than participants who did not. Participants with health-conscious self-identities were more likely to associate water drinking with reward, but this association was disrupted in situations where other aspects of self-identity were prominent. Finally, for many participants drinking patterns from early life persisted into later life and were experienced as hard to change. Our results suggest that reward may be important in habit formation and maintenance. Interventions trying to increase water intake need to make water rewarding in line with drinking outcomes that people value. Early intervention is essential given the persistence of early life drinking habits.
Is probabilistic cuing of visual search an inflexible attentional habit? A meta-analytic review
Authors: Giménez-Fernández Tamara , Luque David , Shanks David , Vadillo Miguel A.
Published: May 2021

In studies on probabilistic cuing of visual search, participants search for a target among several distractors and report some feature of the target. In a biased stage the target appears more frequently in one specific area of the search display. Eventually, participants become faster at finding the target in that rich region compared to the sparse region. In some experiments, this stage is followed by an unbiased stage, where the target is evenly located across all regions of the display. Despite this change in the spatial distribution of targets, search speed usually remains faster when the target is located in the previously rich region. The persistence of the bias even when it is no longer advantageous underpins the claim that this phenomenon is a habit-like process. The aim of this meta-analysis was to test whether the magnitude of probabilistic cuing decreases from the biased to the unbiased stage. A multi-level random-effects meta-analysis of 42 studies confirmed that probabilistic cuing during the unbiased stage was roughly half the size of cuing during the biased stage, and this decrease persisted even after correcting for publication bias. We propose that probabilistic cuing is better understood as evidence of top-down attentional control than as an attentional habit.
Reasserting Humanity after Group-Based Dehumanization
Authors: Howe Lauren Christine , Schumann Karina , Walton Gregory M
Published: May 2021

Research on group dehumanization has focused largely on the perpetrators of dehumanization or its negative emotional and cognitive effects on targets. We theorized that people would also reassert their humanness in response to dehumanizing portrayals of their group. Experiment 1 showed that Black participants responded to even an implied dehumanizing representation of their racial group by emphasizing the extent to which they feel more complex, uniquely human emotions versus more basic, less uniquely human emotions. Experiment 2 showed that Black, but not White, individuals responded to group-based dehumanization by creating more complex self-portrayals. Taken together, these studies begin to illustrate the agency that targets of group-based dehumanization have in responding to dehumanizing threats and how they can use this agency to reassert their humanness.
Benefits of Bayesian Model Averaging for Mixed-Effects Modeling
Authors: Heck Daniel W. , Bockting Florence
Published: May 2021

Bayes factors allow researchers to test the effects of experimental manipulations in within-subjects designs using mixed-effects models. van Doorn et al. (2021) showed that such hypothesis tests can be performed by comparing different pairs of models which vary in the specification of the fixed- and random-effect structure for the within-subjects factor. To discuss the question of which model comparison is most appropriate, van Doorn et al. compared three corresponding Bayes factors using a case study. We argue that researchers should not only focus on pairwise comparisons of two nested models but rather use Bayesian model selection for the direct comparison of a larger set of mixed models reflecting different auxiliary assumptions regarding the heterogeneity of effect sizes across individuals. In a standard one-factorial, repeated-measures design, the comparison should include four mixed-effects models: fixed-effects H0, fixed-effects H1, random-effects H0, and random-effects H1. Thereby, one can test both the average effect of condition and the heterogeneity of effect sizes across individuals. Bayesian model averaging provides an inclusion Bayes factor which quantifies the evidence for or against the presence of an average effect of condition while taking model-selection uncertainty about the heterogeneity of individual effects into account. We present a simulation study showing that model averaging among a larger set of mixed models performs well in recovering the true, data-generating model.

Published: May 2021

Data classification has several problems one of which is a large amount of data that will reduce computing time. SVM is a reliable linear classifier for linear or non-linear data, for large-scale data, there are computational time constraints. The Fractional gradient descent method is an unconstrained optimization algorithm to train classifiers with support vector machines that have convex problems. Compared to the classic integer-order model, a model built with fractional calculus has a significant advantage to accelerate computing time. In this research, it is to conduct investigate the current state of this new optimization method fractional derivatives that can be implemented in the classifier algorithm. The results of the SVM Classifier with fractional gradient descent optimization, it reaches a convergence point of approximately 50 iterations smaller than SVM-SGD. The process of updating or fixing the model is smaller in fractional because the multiplier value is less than 1 or in the form of fractions. The SVM-Fractional SGD algorithm is proven to be an effective method for rainfall forecast decisions.

Published: May 2021

To find the value of employee achievement requires several aspects such as intelligence, aspects of work attitudes, and behavioral. The initial stage of the process is to find the difference between employee and position profile that has been determined by the company where it is called GAP. The next step is to determine the weight of each gap value in three aspects. We multiply the value of 60% for the value of the main factor and 40% for additional factors then add up the two factors to determine the total value. The three factors are assessed based on the percentage determined by the company, namely 25% Intelligence Aspect, 35% Behavioral Aspect, and 40% Work Attitude Aspect. The final results are ranked, and then top ranking is achieved until the last employees who occupy the position of Project Supervisor are employees with ID number: kka_0001. For employees who are likely to fill the position of Purchasing & Logistics are employees with ID number: kka_0040. For employees who are likely to occupy the Estimator position are employees with ID number: kka_0036. For employees who fill the Project Manager position are employees with ID number: kka_0055.

“A work of art is an object that necessitates contemplation”. Latency of visual studies within the Vienna School of Art History?
Authors: Murár Tomáš
Published: May 2021

This article investigates a research method of the so-called Vienna School of Art History, mainly its transformation by Max Dvořák around the First World War. The article suggests the possible influence of Georg Simmel’s philosophy on Dvořák in this time, evident mainly in Dvořák’s interpretation of Pieter Bruegel the Elder’s art, written by Dvořák in 1920 and published posthumously in 1921. This another view on the Vienna School of Art History is then researched in writings on Pieter Bruegel the Elder by Dvořák’s students Hans Sedlmayr and Charles de Tolnay when Tolnay extended Dvořák’s thinking and Sedlmayr challenged its premises – both Tolnay and Sedlmayr thus in the same time interpreted Bruegel’s art differently, even though they were both Dvořák’s students. The article then suggests a possible interpretative relationship of the Vienna School of Art History after its transformation by Max Dvořák with today’s approaches to art (history), mainly with the so-called visual studies.
Intimate listening and sonic solidarity. Radio in the works of Radio Earth Hold collective as a way towards the sonic turn
Authors: Wódz Marta
Published: May 2021

At first glance, radio may seem to be an example of dated technology, overturned by other, more contemporary media. However, the beginning of the 21st century brought an upsurge of radio-related artworks alongside an increased theoretical interest around the broader topic of sound in culture – in response to W. J. T Mitchell’s ‘pictorial turn,’ the ‘sonic turn’ was introduced in 2004 by Jim Drobnick. In this article, I specifically focus on radio as a tool used in visual arts on the example of works by artistic/curatorial collective Radio Earth Hold, observed through the lens of ‘transmission arts’ – a term coined at the end of the 1990s, which recognizes the issue of transmission as political at its core. REH’s works render apparent the potential of the radio voice to become authoritarian as well as to create an intimate experience of listening. By building upon the idea of ‘sonic solidarity’ REH touches upon political topics in a way that can profoundly challenge our thinking and encourage us to reexamine not only the role of radio but also the transmission and communication in or via art – which perhaps could be understood as a way towards the possible sonic turn.
‘Through a Microscope from a Telescopic Distance’: Witkacy, Cameron and the Photography of Faces
Authors: Fedorowicz-Jackowska Aleksandra
Published: May 2021

Witkacy was a central figure of the Polish art scene in the first half of the twentieth century. A painter, writer, philosopher, art theorist, and playwright, he also imaginatively played with the photographic medium. This article will show that the most significant part of his photographic practice, carried on since his youth, was centered on faces. Debating the prevailing view that tends to see Witkacy as a lone visionary, I will argue that Julia Margaret Cameron’s photographic portraits inspired the artist’s style and approach to the genre of photographic portraiture.
Constructing the canon: exhibiting contemporary Polish art abroad in the Cold War era
Authors: Majewski Piotr
Published: May 2021

The article focuses on the attempts of constructing and presenting the canon of Polish modern and contemporary art in the West after World War II. Initially, the leading role was played by Colourists – painters representing the tradition of Post-Impressionism. After 1956 the focus shifted towards artists who drew in their practice on tachisme and informel. However, the most enduring effects brought the consistent promotion of the interwar Polish Constructivism and its postwar followers. The article discusses the subsequent stages of this process, from the famous exhibition at the Paris Galerie Denise René in 1957, through exhibitions such as Peinture moderne polonaise. Sources et recherches (Modern Polish Painting. Sources and Experiments) from the late 1960s, up to the monumental Présences polonaises (Polish Presences) from 1983 (both in Paris), showing that these efforts contributed to securing a permanent position of Polish Constructivism within the global heritage of 20th-century art.
Archaeology of the present. Israeli art after the Al-Aqsa Intifada
Authors: Kędziora Ewa
Published: May 2021

The Al-Aqsa Intifada was the second Palestinian uprising that took place in 2000–2005. The dramatic record of the Intifada expressing itself in waves of recurring terror attacks and the construction of the separation wall on the border between Israel and Palestine overturned the Israeli-Palestinian relationship and triggered international public opinion. The article aims to determine how those events influenced the art scene. The study performs an overview of activities and artistic phenomena which occurred from 2000 through 2015 and problematized the events of the Second Intifada in various ways. The author focuses on individual works of art by both Israeli and international artists as well as art events and exhibitions of the leading kind. The analysis shows the extensive impacts of the Intifada on the artistic environment of that time and leads the author to the conclusion of the Intifada’s prevailing role in shaping politically engaged Israeli art at the beginning of 21 century. The dramatic events came up in creating a new aesthetic of the conflict, resulted in expanding a cultural boycott of Israel as well as challenged the position of politically engaged artists of Israel.
T-Cell Receptor Clustering Methods Used for Single Cell Analysis: Potential Application in Oncology
Authors: Paul Buttigieg Jason , Paul Buttigieg Jason , Helmerson Kristian , Coventry Brendon
Published: May 2021

We know that T-cell activation and effector function is integral for cancer cell destruction in immunotherapeutic treatment in oncology. The fundamental behaviour of T-cells at the time of activation is poorly understood but is likely to be central to this action. Cellular clustering occurs on at least two levels: gathering of multiple mobile cells of similar type, and aggregation between different cell types. Receptors are implicated in both of these processes. Analysis of receptor clustering is a different process whereby receptors form clusters on the cell membrane surface and can be studied to determine their relationship to immune activation. Receptor clustering has been shown to occur in some (perhaps all) cell types, but little is known about this phenomenon, particularly in T-lymphocytes. T-Cell Receptors (TCRs) which are important for the activation of T-lymphocytes. T-cell receptors, also known as cluster of differentiation 3 (CD3) molecules, bind specific antigen to create intracellular signaling in the process of T-cell activation as part of the immune response. The detail of how TCRs physically behave on the T-lymphocyte surface and specifically how they cluster remains unclear, including during the early phases of initiation of immune activation in the T-cell response. The aim of this review is to investigate how receptor clustering that has been studied, can be more effectively studied in the future and what the current evidence suggests about TCR clustering/T-cell activity relationships.
Antimicrobial activity of root canal filling materials
Authors: Maia Jikia
Published: May 2021

The antimicrobial activity of filling materials was studied to improve the quality of treatment of complicated caries in vitro. Resorcin-formalin cement Resodont (“Latus”, Ukraine) - № 1; Endocort zinc oxide-eugenol cement (“Latus”, Ukraine) - No. 2; materials based on zinc oxide eugenol cement with dexamethasone: Endomethasone ivory (Septodont, France) - No. 3 and Endofil ("Produit Dentaires SA", Switzerland) - No. 4. To assess the antimicrobial activity of the studied materials, test microorganism strains were used: Staphylococcus aureus ATCC 25923, Enterococcus faecalis ATCC 6783, Candida albicans ATCC 885-653. As a result of the study, it was established that filling materials have different antimicrobial activity. Resodont has the greatest antimicrobial activity on the test culture. Endomethason is active in relation to the test cultures studied, inferior to Resodont in its antimicrobial properties. Endocort and Endofil have less antimicrobial activity than Resodont and Endomethason, but have approximately equal growth retardation rates. It should be noted that with respect to Staphylococcus aureus, Endocort was found to be almost 1.5 times more active than Endofil. The conducted studies confirm that the materials for filling of root canals by Resodont and Endocort (Latus, Ukraine) have a pronounced antibacterial effect. They are competitive with foreign sealers and are the materials of choice, having a significantly lower cost.

Circumstances, Patterns, and Reporting of Incidents of Workplace Violence among Resident Doctors Posted at Selected Departments of a Tertiary-Care Hospital in Kolkata, India
Authors: Datta Mousumi , Das Adwitiya
Published: May 2021

Objective: Violence at work is a major cause of workplace inequality, discrimination, stigmatization, and conflict. The present study intends to describe the pattern of workplace violence (WPV) in a tertiary-level hospital in India with the objectives of discovering the magnitude of self-reported violence, its type, and the circumstances surrounding and response to such incidents.Material and Methods: The study is of a descriptive type. Its participants were either undergraduate or postgraduate residents at the selected hospital. The data collection tool was and a questionnaire adapted from that used in the World Health Organization’s Workplace Violence in the Health Sector Survey. The period of data collection was one month.Results: Three hundred and twenty two completed questionnaires were analyzed; 76.1% of respondents experienced violence at their workplace. The incidents of psychological violence were higher than those of a physical nature (63.1% vs. 42.9%, respectively). Psychological violence was significantly higher during day shifts and in outdoor or emergency room settings, while physical violence was common during night shifts and in indoor wards. Repeat incidents were more commonly associated with psychological violence. Even though most incidents were not reported, 96.0% of respondents considered WPV a major concern, and the improvement of security measures was most widely suggested as a solution to prevent violence at work.Conclusion: The high incidence of WPV in a tertiary healthcare setting reported in this study is in agreement with the findings of similar studies. Improving security measures and doctor- patient communication may help reduce such occurrences. Designing a robust reporting system and conducting regular and thorough audits of violent incidents can help boost the morale of healthcare staffs as well as plan preventive strategies.

Around 60% of water constitute the human body if about 2% of the body’s water content drop anyone dehydration must have a remarkable effect. Studies show that the loss of body water can break many aspects of brain function. About Eight 8-ounce (237-mL) glasses of water always consult by the physician for a sound person. But unfortunately, If this drinking water becomes impure it affects to develop the various vital dysfunction in our body. Infrequent bowel actions and trouble passing footrest, brain associate dysfunction along with familiar waterborne infections such as looseness, polio, diarrhoea and meningitis are the common conditions that arise for the water-borne pathogen in water.
Gopalganj is a town in Gopalgonj District belonging to the Dhaka Division of Bangladesh. According to the census(cf) of 2011-03-15, 53778 individuals are living here from the divergent profession. For geographical reasons the most of the area specially Gopalganj town along with Gobra, Ghonapra, Tungipara where most government institutions are located the groundwater is not suitable for drinking as Iron and Arsenic are the supremacy amount. That’s why this is the common scenery of these areas to use drinking water jar for the purpose of safe water. For this reason here have already found about 10-15 drinking water jar supplier company.
In this research, we performed the microbiological assay to observe the presence or absence of water-born pathogen on these drinking water containing the water jar along with the morphological characteristics of these pathogens. In point of fact, we found that there is 3 to 6 type of microbes are present in this water. Among these pathogens, there are the supremacy of gram-positive bacteria than gram-negative bacteria along with some moulds co-exist on these microbiomes.
Spor yapan kadınlar bağlamında kadına yüklenen toplumsal beden algısının incelenmesi: Düzce örneği
Authors: KIZILELMAS Fatma
Published: May 2021

Bedene yüklenen toplumsal anlam muhtelif toplumsal yapılarda ve dönemlerde farklılık göstermiş ve beden algısı tarihsel süreçte birçok aşamadan geçmiştir. Beden, bazen fiziksel güzelliği öncelenen bir nesne, bazen içerisinde ruhu barındıran bir varlık, bazen de otomat hareketleri yapabilen bir mekanizma olarak görülmüştür. Kadın bedenine yüklenen anlam da tarihsel süreçlere bağlı olarak değişikliklere uğramıştır. Örneğin geleneksel toplumlarda kadını güzelleştiren şeylerin teşhir edilmesi hoş karşılanmazken, modern/postmodern toplumlarda tam tersi bir durum söz konusu olmuştur. Kadının ideal vücut ölçüleri ile bedeninin estetik yönü öne çıkarılmış ve onların bu durumu gönüllü olarak içselleştirmeleri sağlanmıştır. Söz konusu idealleştirilen vücut ölçülerine erişmek için fiziksel aktivite ve sportif faaliyetler kadınların hayatlarında önemli bir yer edinmiştir. Bu makalede de, toplum tarafından kadın bedenine yüklenen anlamlar ile toplumda ideal olarak gösterilen kadın bedeni algısının, kadının sportif faaliyetler yapmak istemesindeki etkisi incelenmeye çalışılmıştır. Sportif faaliyetler yapan kadının, bedenini şekillendirirken, kadının topluma karşı ve toplumun kadına karşı oluşturduğu perspektifte olası bir değişim ve farklılık ortaya çıkarılmak istenmiş ve kadın bedeni sosyolojik bir bakışla ele alınmıştır. Bu araştırma 2017 yılı Ağustos ayında Düzce ilindeki en fazla kadın üyesi bulunan spor salonunda yapılmıştır. Bu bağlamda sportif faaliyetlere katılan yaş, eğitim ve meslekleri farklı olan 28 kadınla görüşülmeler yapılmıştır. Söz konusu çalışmada nitel araştırma yöntemi ve derinlemesine görüşme tekniği kullanılmıştır. Araştırma neticesinde toplumda ideal olarak kabul gören kadın bedeni ölçülerinden kadınların önemli oranda etkilendiği, bu sebeple bu ölçülere uymayan bedenlerinden memnun olmadıkları ve sportif faaliyetleri daha ziyade toplumda ideal olarak gösterilen ölçülere erişmek için yaptıkları ortaya çıkmıştır. Anlaşıldığı kadarıyla toplumda belirli yer edinmek ve itibarlı olmak için idealize edilen vücut ölçülerine ulaşmak kadınlar için önemli olmakta, bu ölçülere erişememek toplum tarafından kadının iradesini kontrol edememesi ve başarılı olamaması biçiminde algılanmaktadır. Bu durum farkında olarak ya da olmayarak kadınları çok fazla etkisi altına almakta, bedenleriyle ilgili olumsuz değerlendirilme kaygısı yaşatmakta ve özgüvenlerini kötü yönde etkilemektedir.
The implementation of the boundary element method to the Helmholtz equation of acoustics
Authors: Sivak Sergey , Royak Mihail , Stupakov Ilya , Aleksashin Aleksandr , Voznjuk Ekaterina
Published: May 2021

Introduction: To solve the Helmholtz equation is important for the branches of engineering that require the simulation of wave phenomenon. Numerical methods allow effectiveness’ enhancing of the related computations. Methods: To find a numerical solution of the Helmholtz equation one may apply the boundary element method. Only the surface mesh constructed for the boundary of the three-dimensional domain of interest must be supplied to make the computations possible. This method’s trait makes it possible toconduct numerical experiments in the regions which are external in relation to some Euclidian three-dimensional subdomain bounded in the three-dimensional space. The later also provides the opportunity of not using additional geometric techniques to consider the infinitely distant boundary. However, it’s only possible to use the boundary element methods either for the homogeneous domains or for the domains composed out of adjacent homogeneous subdomains. Results: The implementation of the boundary elementmethod was committed in the program complex named Quasar. The discrepancy between the analytic solution approximation and the numerical results computed through the boundary element method for internal and external boundary value problems was analyzed. The results computed via the finite element method for the model boundary value problems are also provided for the purpose of the comparative analysis done between these two approaches. Practical relevance: The method gives an opportunityto solve the Helmholtz equation in an unbounded region which is a significant advantage over the numerical methods requiring the volume discretization of computational domains in general and over the finite element method in particular. Discussion: It is planned to make a coupling of the two methods for the purpose of providing the opportunity to conduct the computations in the complex regions with unbounded homogeneous subdomain and subdomains with substantial inhomogeneity inside.
A post-quantum digital signature scheme on groups with four-dimensional cyclicity
Authors: Moldovyan Nikolay , Moldovyan Dmitry
Published: May 2021

Introduction: Development of practical post-quantum signature schemes is a current challenge in the applied cryptography. Recently, several different forms of the hidden discrete logarithm problem were proposed as primitive signature schemes resistant to quantum attacks. Purpose: Development of a new form of the hidden discrete logarithm problem set in finite commutative groups possessing multi-dimensional cyclicity, and a method for designing post-quantum signature schemes. Results: A new form of the hidden discrete logarithm problem is introduced as the base primitive of practical post-quantum digital signature algorithms. Two new four-dimensional finite commutative associative algebras have been proposed as algebraic support for the introduced computationally complex problem. A method for designing signature schemes on the base of the latter problem is developed. The method consists in using a doubled public key and two similar equations for the verification of the same signature. To generate a pair of public keys, two secret minimum generator systems  and  of two different finite groups G and G possessing two-dimensional cyclicity are selected at random. The first public key (Y, Z, U) is computed as follows: Y = Gy1Qy2a, Z = Gz1Qz2b, U = Gu1Qu2g, where the set of integers (y1, y2, a, z1, z2, b, u1, u2, g) is a private key. The second public key (Y¢, Z¢, U¢) is computed as follows: Y¢ = Hy1Vy2a, Z¢ = Hz1Vz2b, U¢ = Hu1Vu2g. Using the same parameters to calculate the corresponding elements belonging to different public keys makes it possible to calculate a single signature which satisfies two similar verification equations specified in different finite commutative associative algebras. Practical relevance: Due to a smaller size of the public key, private key and signature, as well as approximately equal performance as compared to the known analogues, the proposed digital signature scheme can be used in the development of post-quantum signature algorithms.

A huge amount of data obtained during last 30 years in multiple translational works allowed both to break particular tumor types into subgroups based on molecular markers but also to create pan-tumor subgroups based on particular markers. These evidence suggest the new approach to diagnostic and treatment algorithms should be implemented. Despite the rarity of some molecular markers the possibility of their presence must be kept in mind in order to achieve optimal results in patient’s treatment.

Unlicensed gold mining (PETI) is rife in the community, especially entrepreneurs / capital owners since the last ten years in Merangin Regency. Lack of awareness of negative impacts is a problem that needs serious attention from the government. There are miners who come from outside and from the community itself. Even though PETI is difficult to overcome, many of the people who own the land have processed it to be planted with rice again. In other places or areas in Indonesia, many ex-PETI lands cannot be planted with rice anymore because they have already contaminated with mercury. Due to the fact that many ex-PETI lands have been re-processed into paddy fields in Merangin Regency, a research was conducted which took place in Pangkalan Jambu District. The reason for choosing Pangkalan Jambu sub-district as the research location is because in this sub-district the largest area of ​​land in Merangin Regency is being mined by the community. The research was conducted with a case study qualitative approach with data collection techniques, observation, interviews and documentation. The purpose of this study was to examine the processing of ex-PETI rice fields into reclamation. The results of the study concluded that the reclamation activity was carried out after several landowners tried to plant rice on the ex-PETI land which was successful and did not encounter any significant obstacles. Starting from here, other residents did the same thing and it turns out that it continues to grow until now. As the reason why rice plants can thrive, it turns out that in this place the miners do not use mercury when mining. Previously, the area of productive rice fields was 1202 ha and now, of the eight villages, the number of rice fields that have been reproducing (reclaimed) is 139 ha. There are 804 ha of rice fields damaged by PETI and there are 259 ha of land that are not damaged but have not yet operated or have not recovered and need to be reclaimed again.
