Published: April 2023

Background- Flaveria trinervia (Asteraceae), a medicinal herb has been used in Indian traditionl medicine to cure jaundice. Reports on phytochemical and pharmacological investigations are very scarce. A phytoconstiuent Tridecan-1-ol and screened for hepatoprotective activity. -To evaluate hepatoprotective effects of Tridecan-1-ol against CCl4 induced hepatic damage on Wister albino rats. Methods- Tridecan-1-ol was isolated from petroleum extract of Flaveria trinervia using silica gel column chromatography and the structure was confirmed by IR, MASS,and 1H NMR spectroscopic studies. The parameters employed to confirm the hepatoprotectivity were the estimation of liver function serum markers such as total bilirubin, total protein, alanine transaminase, aspartate transaminase, alkaline phosphatase activities and the histological profile of the liver tissue. Results-The LD50 of petroleum ether extract and the constituent Tridecan -1-ol was found to be 500 and 150 mg/kg body weight respectively. Tridecan -1-ol showed significant hepatoprotective activity than the crude extract and it was compared with the standard hepatoprotective drug silymarin. The histological profile of the liver tissue ofTridecan-1-ol administered rats showed the presence of normal hepatic cords, absence of necrosis and fatty infiltration as similar to the controls. Conclusion-Tridecan-1-ol afforded significant hepatoprotectivity against CCl4 induced liver damage and supported the traditional claim of Flaveria trinervia as a hepatoprotective herb.

This study aims to examine the effect of Return On Assets, Leverage, and Capital Intensity on Tax Avoidance. The population in this study were all pharmaceutical companies listed on the Indonesia Stock Exchange during the 2017-2019 period, namely 10 companies. Sampling in this study using the purposive sampling method, in order to obtain 6 companies that meet the criteria. Regression analysis in this study using Multiple Linear Regression Analysis. Meanwhile, to test the hypothesis using the t-test and F-test. The results of this study partially show that the first hypothesis of the Return On Assets variable has no effect on tax avoidance. This means, if the Return on Assets decreases, the company tends to do tax avoidance. The second hypothesis is that the Leverage variable has an effect on Tax Avoidance. This means that if Leverage increases, the company tends to do Tax Avoidance. The third hypothesis is that the Capital Intensity variable has an effect on Tax Avoidance. This means, if there is an increase in capital it will cause the company to tend to do tax avoidance. The fourth hypothesis is that Return on Assets, Leverage, and Capital Intensity simultaneously affect the practice of Tax Avoidance with an R2 value of 56.8%. This shows the effect of all these variables is 56.8% on the Tax Avoidance variable.

Preparation and Use of Low-Cost Electrochemical Sensors
Authors: Janegitz Bruno
Published: April 2023

Since the decade of the 90s when the first works of professor Joseph Wang were published, screen-printed electrodes have been proposed for many objectives. In the first works in Brazil a few years later, some authors proposed electrochemical sensors using graphite from batteries, which provide great results for the determination of several analytes.1 In another interesting work, Professor Lucio Angnes (USP) and collaborators prepared gold electrodes from CD, which presented a thin film of the noble metal.2 They obtained an extremely low-cost electrochemical sensor. After that, this research line gained notoriety in Brazil, and the number of groups and papers has increased considerably. In this regard, we can highlight some researchers that have been working on low-cost and disposable electrochemical sensors, including Lauro Kubota (UNICAMP), Luiz Humberto Marcolino Junior (UFPR), Márcio Fernando Bergamini (UFPR), Ronaldo Censi Faria (UFSCar), Éder Cavalheiro (USP), Osvaldo Novais de Oliveira Junior (USP), Sergio Spínola (USP), Murilo Santiago (CNPEM), Renato Souza Lima (CNPEM), Orlando Fatibello Filho (UFSCar), Wendell Coltro (USP), William Reis (UNICAMP), and Thiago Paixão (USP). The laboratory of Sensors, Nanomedicine, and Nanostructured Materials (LSNano) located at UFSCar Araras has also developed low-cost sensors using recyclable materials and conductive inks with simple preparation. Low-cost electrodes can be prepared with infinite possibilities by using different substrates, such as circuit boards,3 acetate sheets,4 and polyethylene terephthalate (PET) from bottles5 as well as paper6. In the last example, various types of papers have been applied in this area, including cardboard,7 waterproof,6 and adhesives8. Therefore, materials that we use daily can become important devices with great applications. There are many options to produce low-cost electrochemical sensors, including pencil drawing, stencil, laser scribing, and screen-printing techniques.9 The strategy depends on the subject and the materials that have been deposited to be used as conductors. In this context, the screen-printing technique is come from the t-shirt preparation and is an excellent alternative to produce hundreds of sensors in a few minutes. They can be applied by using different electrochemical techniques, such as potentiometry, voltammetry, and electrochemical impedance spectroscopy. For this purpose, low-cost inks, which are made of a polymer and a conductive material, are necessary. Conductive inks can be prepared with water based-polymers,10 nail polish,11 and traditional polymers based on organic solvents12. Otherwise, graphite carbon nanotubes and/or graphene and carbon dots have been used as conductive carbon-based materials.13 Also, metallic nanoparticles such as copper, platinum, and gold can be great alternatives for this intention but can be quite costly.

The use of multimedia as a tool for delivering learning content instead of the traditional classroom learning practice is gaining popularity nowadays. CAI is the use of computer programs that are available both online and offline for instruction. The objective of this paper is to conduct a systematic literature review (SLR) on computer assisted (or aided) instruction (CAI) for five years period from 2018 to 2022 at all educational level. The objective of this study is to determine the research distribution on CAI, to identify the methods of data collection used in studies on CAI and to identify the types of CAI investigated in the research community from 2018 to 2022. This SLR uses review protocol for the selection of primary studies for inclusion in the study from the pool of literature available in the research community. The results of the review shows that the highest publication on CAI in the review period was in 2020 and most researchers used achievement test for collection of data on CAI in the reviewed period. The study also found out that ‘Computer-Based Simulation’ is the popular type of CAI used in experiments by researchers in the period of review. The use of CAI for teaching and learning activities enables flexible and efficient interaction among students and educators. This is a critical factor for enhancing learners’ academic achievement. In conclusion, it is recommended that further research be conducted on CAI to promote its adoption in education systems.

Technoism: A new form of prejudice and discrimination
Authors: Jörling Moritz , Heuvinck Nico , KERVILER DE , rucker derek
Published: April 2023

History has demonstrated that people discriminate against other humans, groups, and species because of pure “otherness” rather than merits. This paper explores the idea that some humans evince technoism— a form of prejudice and discrimination against technology; people dismiss objective performance criteria in favor of general human superiority beliefs. In twelve studies (seven reported in supplement; N = 3,274) and multiple contexts, we find technoism varies among people and introduces bias in responding to technology, with negative consequences for both oneself (Studies 1, 2) and fellow humans (Studies 3, 4). Thus, as a form of discrimination, technoism poses risks to the welfare of individuals and society. As such, understanding technoism is required to move society toward a fact-based instead of a prejudice-based evaluation of technology. By revealing technoism as a construct, this paper offers a first contribution to this issue and opens a new perspective for discourse on human-technology interaction.
Negotiators Deceive Much Less than We Think: A Theory of Distrust in Negotiation
Authors: Garber-Lachish Shira , Moran Simone , Keysar Boaz , Bereby-Meyer Yoella
Published: April 2023

Negotiators face two dilemmas, whether to be honest and whether to trust their counterparts. We propose a theory that describes how they approach these dilemmas and show the consequences. We argue that negotiators adopt different models of motivations for the two dilemmas. When deciding whether to trust, they assume the other is largely motivated by greed. When deciding whether to deceive, negotiators are motivated not only by greed but also by moral-image concerns and anticipated guilt. Four studies (N = 931) provide evidence for this theory. We show that people grossly overestimate how much negotiators would deceive and that this results from overrating the extent to which greed motivates other negotiators’ behavior. In contrast, we show that negotiators are actually largely concerned with moral consequences, and consequently deceive much less than expected. This discrepancy is important because it could impede initial trust in negotiation, and consequently lead to inefficient agreements.
The uniqueness of dominance: structural and criterion discriminability
Authors: Altschul Drew , Moore Adam
Published: April 2023

Dominance, a trait capturing assertiveness, leadership, and social boldness, is sometimes subsumed as a facet of extraversion, but might be a blended trait, overlapping with extraversion and openness. We hypothesized that while dominance overlaps with these traits in some areas, dominance also is a uniquely discriminable construct. In a series of preregistered analyses, we looked for the ideal factor structure of dominance, extraversion, and openness, and predicted associations with external variables that would demonstrate the discriminability of each of these three personality constructs. We found that dominance is always best modeled with its own factor, though overlap is present and can be appropriately modeled. We also confirmed that dominance is associated with anger and aggression, while extraversion and openness are not. The further discriminability of dominance is discussed.
THE LABOR INPUT IN THE AGE OF ARTIFICIAL INTELLIGENCE
Authors: ruggeri giuseppe
Published: April 2023

In this paper I suggest that autonomous machines are more akin to human workers than to capital and should be treated as a component of the labor input. I show that, when the returns to intellectual property products are included in labor income, the observed secular decline in the labor income share in the United Sates vanishes. I suggest greater focus of economic research on the dynamics of the relationship between human labor and automatic labor.
Talking Politics: Vladimir Putin’s Narrative on Contemporary History (2019-2022)
Authors:   European University at Saint-Petersburg, Russia, Miller Alexei I. ,   Institute of Scientific Information for Social Sciences of the Russian Academy of Sciences
Published: April 2023

This paper looks at Vladimir Putin’s public statements and articles devoted specially to historical issues which were published in 2019 through 2021 (with reference to the first such article published in 2009). The Russian President’s statements and extended texts on history are scrutinized in this paper as political messages having a certain target audience and political goals. The analysis has revealed a rapid evolution of Putin’s approach to relations with the West in 2019-2021, from attempts to reanimate the dialogue to a sharp confrontation. It has also proved the hypothesis that Putin’s views on history serve not so much as the basis for his political decisions as instruments of their legitimization for society and opponents.
Russian Foreign-Policy Culture and the Horde: A Hypothesis
Authors:   National Research University–Higher School of Economics, Moscow, Russia, Bordachev Timofei V.
Published: April 2023

This article scrutinizes the historical impact of the Mongolian Horde on Russia’s foreign policy behavior. The author comes up with a hypothesis that relations with the Horde were not only important for Russia during the critical historical period of its formation, but also largely determined its unique foreign-policy culture and practical implementation of Russian foreign policy in subsequent periods. The author maintains that the key element of this impact was peaceful integration of the powerful neighbor which posed the biggest threat to the Great Russians for more than two hundred years.

One of the possible uses of chalcogenide glasses is their application in phase change memory devices. The operation of these non-volatile memories is based on the use of an alloy with chalcogenide elements as a sensitive material, taking advantage of the great contrast in electrical resistance between the amorphous and crystalline states. The Sb70Te30(atomic percentage) alloy stands out among the chalcogenide materials with these properties. On the other hand, the knowledge of the microscopic mechanisms of the amorphous alloys crystallization allows microstructural control to optimize properties. At this point, differential scanning calorimetry (DSC) has been widely used for the determination of the thermal stability of amorphous alloys. Previously we have started the study of the crystallization kinetics ofSb70Te30amorphous alloys. In this work, a procedure based on the so-called isokinetic hypothesis has been applied to carry out the kinetic analysis of the calorimetric data of continuous heating. In particular, the so-called master curve of the crystallization kinetics of this alloy is determined.

The detection of temporally coincident signals plays an important role in different technological applications for metrology and communication, and particularly, in the area of quantum optics. In this sense, the simultaneous detection of two or more photons allows one to take advantage of the non-classical features of light that manifest themselves in certain types of correlations that cannot be described classically. We present here the development of programmable modules, by using FPGA technology, which are part of the coincident pulse detection and counting system. Our implementation, in a development board from Xilinx, allows to determine when two or more pulses overlap within a temporal window, with a configurable width in the range of 1 and 255 ns to compensate for possible path differences. We obtained the photodetection statistics result of the single and coincident pulse measurements and compared them with that predicted by a theoretical analysis. In addition, we have emulated the signals corresponding to different photon sources through a beam splitter, and obtained the photodetection statistics from which we determine, for each case, the second order correlation function g(2)(τ).

Authors: Zienkiewicz Aleksandra , Podciborski Tomasz , Terebukh Andrii
Published: April 2023

Motives: In recent years, the popularity of military tourism has increased considerably in Central and Eastern European countries, especially among tourists who have an interest in military history and technology. Due to the general scarcity of methods and studies examining alternative uses of former military bases, including coastal artillery bases, a reliable method for assessing the value of such sites for military tourism should be developed. The study presents the history of the analysed military bases, and it examines the extent to which the existing facilities could be converted into tourist attractions. An innovative method for evaluating the tourism potential of defunct military bases was proposed and verified, and the required changes for improving the accessibility and applicability of military facilities for educational and tourism purposes were described. Two former military sites in Koszalin coastal region were selected for the study.
Aim: The main aim of the study was to propose an original method for assessing alternative uses of former coastal military bases, and to evaluate the educational and tourism potential of former military bases on the Koszalin Coast (a subregion of the South Baltic Coast) on the example of two former military facilities: Anti-Aircraft Artillery Division No. 68 in Łeba and Anti-Aircraft Artillery Division No. 66 in Naćmierz.
Results: The results of the study indicate that the evaluated military sites have considerable tourism potential, in particular for tourists who have an interest in military history. An analysis of exogenous as well as endogenous (architectural and historical features) factors revealed that both sites could attract tourists, including visitors who are not strictly interested in military facilities. The assessment conducted using the proposed method demonstrated that the Anti-Aircraft Artillery Division No. 68 in Łeba is characterised by high tourist attractiveness, whereas the Anti-Aircraft Artillery Division No. 66 in Naćmierz is characterised by moderate tourist attractiveness.
