Authors: Moon Andrew M. , Kim Hannah P. , Barritt A. Sidney , Darling Jama , Arora Shifali 
Published: March 2020

OBJECTIVES:
We performed a study to assess the effects of a quality improvement (QI) initiative on the rates of postvariceal bleeding surveillance upper endoscopy (EGD).

METHODS:
We identified patients with cirrhosis hospitalized with variceal bleeding and assessed the rates of timely (≤4 weeks) EGD before and after a QI initiative.

RESULTS:
Preintervention: 16% (5 of 32) of patients underwent timely surveillance EGD. We developed a standardized ordering template for gastroenterology fellows and reserved postvariceal EGD scheduling slots. Postintervention: 43% (12 of 28) of patients underwent timely surveillance EGD.

DISCUSSION:
A QI intervention was associated with a 27% absolute increase in timely surveillance EGDs.
Trade Policy is Back in the News: Will Voters Care?
Authors: Guisinger Alexandra 
Published: March 2020

AbstractDuring the 2016 election cycle, both Donald Trump and Bernie Sanders received roars of approval from supporters when discussing plans to roll back decades of trade liberalization and more specifically North American Free Trade Agreement (NAFTA). In the past, protectionist politicians who failed to follow through on promises paid little electoral cost, arguably because NAFTA received relatively little media or political attention after it was passed. Now in the spotlight, could trade policies cost President Trump voters in 2020? I argue that the highly partisan nature of today’s trade discourse – a new dimension for trade opinion – creates obstacles for electoral accountability because preferences follow rather than drive partisanship. Drawing on previous research and a 2017 survey experiment fielded before and after Trump’s trip to China, I show that the ability of trade messaging to cross party lines has weakened and that Trump’s followers strongly react to information cues from Trump but fail to react to information based accusations of flip flopping on his most prominent trade related promise: increased protection against China. The ability of politicians to shape preferences rather than respond to the will of constituents calls into question the electoral connection on critical government policies even when they become salient.
It’s Trump’s Party and I’ll Cry if I Want To
Authors: Rapoport Ronald B. , Reilly Jack , Stone Walter J. 
Published: March 2020

AbstractBased on analysis of a multi-wave national sample panel of Republican identifiers, we show the increasing coherence among rank and file Republicans around evaluations of Donald Trump. Differences between Republicans who preferred Trump for the GOP nomination and those who preferred another candidate (but, unlike the Never Trump group who said they could not support him in the general election if he won the nomination) are muted by the general election and 2018 waves. While “Never-Trumpers” in the nomination wave maintain their affective distance from Trump in the general election and 2018 waves, their evaluations become less negative. Our analysis suggests that Republicans’ favorability toward Trump increasingly aligned with their attitudes toward the Republican Party and their support for Trump’s effort to build a southern-border wall.
How to get to the other side of the mitochondrial inner membrane – the protein import motor
Authors: Mokranjac Dejana 
Published: March 2020

Abstract
Biogenesis of mitochondria relies on import of more than 1000 different proteins from the cytosol. Approximately 70% of these proteins follow the presequence pathway – they are synthesized with cleavable N-terminal extensions called presequences and reach the final place of their function within the organelle with the help of the TOM and TIM23 complexes in the outer and inner membranes, respectively. The translocation of proteins along the presequence pathway is powered by the import motor of the TIM23 complex. The import motor of the TIM23 complex is localized at the matrix face of the inner membrane and is likely the most complicated Hsp70-based system identified to date. How it converts the energy of ATP hydrolysis into unidirectional translocation of proteins into mitochondria remains one of the biggest mysteries of this translocation pathway. Here, the knowns and the unknowns of the mitochondrial protein import motor are discussed.
Heavy metals and 137Cs levels in macrophytes and temporal distribution in sediments – application for estuarine environment status assessment (Vistula Lagoon – southern Baltic)
Authors: Zalewska Tamara , Brzeska-Roszczyk Paulina , Danowska Beata , Pełechaty Mariusz 
Published: March 2020

Abstract
The paper presents the first data on the concentrations of heavy metals (Cd, Pb, Zn, Cu, Ni, Cr, Mn) and 137Cs and their contamination ratios (CR) in the most abundant species of macrophytes in the Vistula Lagoon. No significant differences in the concentrations of heavy metals and 137Cs between macrophyte taxa or the influence of rivers flowing into the Vistula Lagoon on heavy metal concentrations in the area were found. The concentrations of heavy metals in macrophyte taxa varied in the following ranges: Cd – 0.1–0.7 mg kg−1 d.w.; Pb – 0.5–5.0 mg kg-1 d.w.; Zn – 29–390 mg kg-1 d.w.; Cu – 2.5–8.3 mg kg-1 d.w.; Ni – 0.4–6.8 mg kg−1 d.w.; Cr – 0.5–2.8 mg kg−1 d.w.; Mn – 380–8500 mg kg−1 d.w. Since the 1990s, a decline or stable state of heavy metal concentrations in bottom sediments has been observed, reflecting changes in the environment of the Vistula Lagoon. The linear sedimentation rate in the Vistula Lagoon was 3.3 mm y−1. The results presented in the paper can serve as a baseline for assessing changes in the environmental status of the Vistula Lagoon, which may occur as a result of future investments, including building a new navigable canal through the Vistula Spit.
Monoids, their boundaries, fractals and C*-algebras
Authors: dal Verme Giulia , Weigel Thomas 
Published: March 2020

AbstractIn this note we establish some connections between the theory of self-similar fractals in the sense of John E. Hutchinson (cf. [3]), and the theory of boundary quotients of C*-algebras associated to monoids. Although we must leave several important questions open, we show that the existence of self-similar ℳ-fractals for a given monoid ℳ, gives rise to examples of C*-algebras (1.9) generalizing the boundary quotients \partial C_\lambda ^*(\mathcal{M}) discussed by X. Li in [4, §7, p. 71]. The starting point for our investigations is the observation that the universal boundary of a finitely 1-generated monoid carries naturally two topologies. The fine topology plays a prominent role in the construction of these boundary quotients, while the cone topology can be used to define canonical measures on the attractor of an ℳ-fractal for a finitely 1-generated monoid ℳ.
Człowiek jako wytwór siebie samego. Lem, transhumanizm i dwie koncepcje autentyczności
Authors: Gomułka Jakub , Klimas Mariusz , Palm Jakub 
Published: March 2020

Stanisław Lem, a philosopher and futurologist, in his many works devoted much attention to the condition of human and the relation between human and technology. He coined the term ‘autoevolution’ in the course of forecasting unlimited technological augmentation of human abilities. Nowadays, the term may be associated with the conceptions presented by transhumanism, a 20th-century-born philosophical movement which advocates radical transformation of Homo sapiens by means of the achievements of scientific and technological progress. Lem’s attitude towards such a transformation of human is complicated yet ultimately critical due to the fact that it poses a threat to human culture as such. The phenomenon of autoevolution undermines existing values and raises a question of authenticity of a future posthuman. We examine dependence between technology and culture, present Lem’s conception of autoevolution and his philosophy of culture, then we sketch a post-metaphysical dispute about authenticity, and finally show that Lem’s thought ­belongs to one of the arguing sides.
Oświeceniowa wizja nauki w ujęciu Józefa Sołtykowicza, jako przykład refleksji filozoficznej z kręgu Towarzystwa Naukowego Krakowskiego
Authors: Psica Sylwia 
Published: March 2020

The article concentrates on the analysis of the Enlightenment periods vision of science by Josef Sołtykowicz. His theories are examples of philosophical reflection of the Cracow Science Society. The starting point was the outline of the political and scientific situation from the second part of the XVII century to the first part of the XIX century also referring to the author’s biography.The main part of the article is the analysis of two Dissertations by Sołtykowicz published by the Cracow Science Society their yearly publication, in 1818 and 1820.The following points were taken into account: The roots of the society’s activities, the relationship between science and faith, popularizing knowledge, criticism of Rousseau and anthropological analysis of the roots, of the negative view of knowledge. These theories are worth analysing, unfortunately so far the philosophical thought of the members of CSS, has not encouraged work on them as they deserved. At the same time we can expect that the work of the scientists from the CSS significantly impacted on the progress of the philosophical reflection in Cracow, and also the wider picture of modern polish scientific culture.
Potrójna kreacja świata w ujęciu Michała Sędziwoja
Authors: Cygan Milena 
Published: March 2020

The question of the beginning of the world, it’s first rule, genesis and structure followed humanity since the dawn of time, becoming a source for philosophy and science. Search for a rational answer to that question lead, throughout the ages, to a creation of many cosmogonic concepts which referenced various philosophical traditions. While they currently hold only historical value, in many cases they contained ideas, sometimes still very inarticulate, which revolutionized the science in later years. One of such concepts was proposed by Michael Sendivogius, a Renaissance polish alchemist. In his approach, creation of world is dynamic and multiphase. In his vision, the world is something, which is subject to evolution (though he does not use this term), inevitably changes, and thus undergoes a permanent creation. In this creation of the world, as Sendivogius describes it, one can distinguish three fundamental stages, responsible for which are three factors: God, Nature and man. The goal of this article is to present how, according to Sendivogius, the world is created, what tasks in this continuous process are carried out by God, Nature or the man, and in what relations they remain, in regards to themselves and the world they create.

One of the strategies in the establishment of in vitro oxidative stress models for neurodegenerative diseases, such as Alzheimer’s disease (AD), is to induce neurotoxicity by amyloid beta (Aβ) peptides in suitable neural cells. Presently, data on the neurotoxicity of Aβ in neural cells differentiated from stem cells are limited. In this study, we attempted to induce oxidative stress in transgenic 46C mouse embryonic stem cell-derived neurons via treatment with Ab peptides (Aβ1-42 and Aβ25-35). 46C neural cells were generated by promoting the formation of multicellular aggregates, embryoid bodies (EBs) in the absence of leukemia inhibitory factor (LIF), followed by the addition of all-trans retinoic acid (ATRA) as the neural inducer. Mature neuronal cells were exposed to different concentrations of Aβ1-42 and Aβ25-35 for 24 h. Morphological changes, cell viability, and intracellular ROS production were assessed. We found that 100 µM Aβ1-42 and 50 µM Aβ25-35 only promoted 40% and 10%, respectively, of cell injury and death in the 46C-derived neuronal cells. Interestingly, treatment with each of the Aβ peptides resulted in a significant increase of intracellular ROS activity, as compared to untreated neurons. These findings indicate the potential of using neurons derived from stem cells and Aβ peptides in generating oxidative stress for the establishment of an in vitro AD model that could be useful for drug screening and natural product studies.

Service Gap of Selected Public and Private Commercial Banks in Bangladesh
Authors: Akhter Mst. Momena 
Published: March 2020

The economy of a country is largely dependent on banking sector. In this case, Bangladesh is not exceptional. Both public and private banks play a vital role in the economy, making up one of the biggest providers of services in the Bangladesh economy. In the current banking environment, service quality is one of the main weapons, which enables the banks to differentiate from each other. It is said that service quality has become an important factor to survive and succeed in the banking sector. Hence, providing a better service quality is vital, as banks have to compete for customers. In this paper, the factors leading to the service provider gaps in case of selected public and private commercial banks have been identified and measured and it attempts to show the relationship between the provider gaps of these banks and the gap between expected service and perceived service (customer gaps). Two public commercial banks (Janata Bank Ltd., and Agrani Bank Ltd.) and two private commercial banks (Dutch Bangla Bank Ltd., and Prime Bank Ltd.) were selected for the purpose of the study. In this paper there is an endeavor to recognize whether the service provider gaps and the customer gaps are correlated and takes into consideration the problems of organizational quality gaps where the quality losses occur. This will help the management of these banks to know where the service gaps lie and how to close the gaps for providing quality service to their clients. This study shows that the overall service gap is higher in the public commercial banks in comparison to the private commercial banks. To remove this gap and to improve the overall service quality this paper has recommended some measures for both public and private commercial banks in Bangladesh.

Published: March 2020

In present situation, companies can gain strong competitive advantage through applying effective and efficient human resource practices. If the human resources are managed properly, they can contribute to the success for the company. The effective management of human resource is possible through the implementation of sound HRM practices. . The main objective of this research is studying the impact of HRM practices on employee performance in the context of cement industry in Bangladesh. For this purpose the researchers have tried to investigate impact of the various components of HRM practices on employee performance of a sample of 160 employees from seven cement companies listed in the Dhaka Stock Exchange. The data were analyzed by a regression analysis to determine the impact of HRM practices on employee performance. The result shows that training & development and opportunity for career development have a significant positive impact on employee performances. On the other hand, Performance appraisal, Compensation & Benefits, and Leadership Practices have a positive impact on employee performance but the impact is not significant in the context of cement industry in Bangladesh. Moreover, work life balance has a negative impact on employee’s performance. Furthermore, efficient management of human resources can increase the performance of the employees of the cement companies in Bangladesh. JEL Classification Code: M12; J53
The relationship of sleep mechanisms and epileptogenesis
Authors: Kozhokaru A. B. , Vlasov P. N. , Orlova A. S. 
Published: March 2020

Close links between epilepsy and sleep is doubtless; however, the available literature does not allow for its unequivocal interpretation from the common pathophysiological mechanisms' perspective. GABAergic neuronal deficiency is believed to be the neurochemical background of the intimate mechanisms of sleep and epileptogenesis. Sleep impacts the epileptiform activity, with an increase in epileptiform discharge during NREM and a decrease during REM phases. Sleep deprivation may complicate the course of epilepsy, while epileptic attacks may change the sleep structure and quality. Anti-epileptic agents exert diverse effects on the sleep architectonics; they can induce sedation or increase alertness. Our potential to correct the results of the pathological interplay between sleep mechanisms and epilepsy are rather limited and are frequently overestimated by clinicians. Investigation of the interrelationship between epileptic seizures and sleep and the use of polysomnography can substantially add to the diagnosis of the epileptic syndrome and define the subsequent outcomes.
Improvement technique of direct torque control of DFIG based on wind energy conversion system
Authors: Cherifi Djamila , Miloud Yahia 
Published: March 2020

This paper presents a comparative study between two strategies for the direct torque control (DTC) of the doubly fed induction generator based on the wind energy conversion system. The first method is a conventional DTC and it is based on hysteresis controllers where the torque and the flux are regulated by these controllers. The second one is DTC by space vector modulation strategy (DTC-SVM) where the torque and flux are regulated by PI controllers. The main feature of the proposed (DTC-SVM) strategy is the reduction of torque and flux ripples. Simulation results of this proposed system were analysed using the MATLAB environment.
Keywords: Doubly fed induction generator (DFIG), wind power generation systems, direct torque control (DTC), space vector modulation (SVM).

Published: March 2020

Cassava-based industry in Jember Regency had good potential to be developed. The development could be done by forming industrial clusters. Cassava-based industrial clusters could be developed through determining potential locations. The study aimed to provide information about determining the location of the cassava-based industrial cluster development in Jember Regency. The study was conducted using the location quotient (LQ) method and the scalogram method. The results showed that the sub-districts in Jember Regency had potential locations for developing cassava-based industrial clusters, such as Kaliwates Sub-District, Patrang Sub-District, and Sumbersari Sub-District. The three sub-districts had advantages compared to other sub-districts in terms of the concentration of LQ values produced by cassava-based products. Scalogram results showed sub-districts in the highest service center hierarchy, i.e. Kaliwates Sub-District, Patrang Sub-District, and Sumbersari Sub-District. All three sub-districts had complete facilities compared to other sub-districts so that they could become centers of economy and trade. Based on the results of the LQ method and scalogram, the location of the cassava-based industrial cluster development in Jember Regency was determined in Kaliwates Sub-District, Patrang Sub-District, and Sumbersari Sub-District.
