Authors: Cuanda Tiffany
Published: June 2021

The crisis of decreasing demand and exchange rates for MSMEs for Hero Supermarkets. Public expenditure allocation for 2019-2020. The increase in expenditure allocation was seen for the food expenditure group from 18.8 percent to 23.3 percent and for savings by 16.9 percent to 19.2 percent. Visitors are increasing in times of the new normal. Positive growth will take place in 2021, especially in the second quarter that comes along with Ramadan and Eid. In 2020, HERO bears a loss for the year of up to Rp 1.21 trillion. This number swelled compared to the previous year which was recorded at Rp 28.22 billion. So there is a decrease in the exchange rate. The existence of PSBB restrictions caused a decrease in the number of customer visits to the hero supermarket inside the mall. PSBB triggers changes in customer shopping behavior and patterns of demand for goods. That's the decline in sales. So that the Covid-19 pandemic is again hampering people's purchasing power. As a result of the COVID-19 pandemic, the number of people who are not working has resulted in many companies being laid off so that many people are not working, resulting in a large number of unemployed. Hero Supermarket also reduces the number of employees and monitors prices. During the pandemic, working capital assistance will be provided for MSME business actors. Communities cut non-essential needs by reducing, for example, children's snacks at school by providing food from home. This will overcome the decline in income in the MSME trade sector. Hero supermarket directly cooperates with farmers, a coaching program is carried out with the hope that farmers will be able to directly distribute their products to Hero Supermarkets. The next assisted agricultural program is the hero group in collaboration with the food crop and multicultural agriculture office of Central Java province. hero supermarket thousands of workers lost their workers due to MSMEs.
Independent Media Under Pressure: Evidence from Russia
Authors: Paskhalis Tom , Rosenfeld Bryn , Tertytchnaya Katerina
Published: June 2021

Existing literature recognizes growing threats to press freedom around the world and documents changes in the tools used to stifle independent press. However, few studies investigate how independent media respond to state pressure. Do independent outlets comply, orienting coverage to favor regime interests? Or does repression encourage more negative coverage of the regime instead? To shed light on these questions, we investigate how the abrupt removal of independent outlet TV Rain from Russian television providers influenced its coverage. We find that shortly after TV Rain was dropped by providers, the tone of its political coverage became more positive and its similarity with state-controlled television increased. However, these effects were short-lived. Additional evidence suggests that subscription revenue contributed to the station's resilience. These findings, from the first causal test of how attacks influence independent media coverage in a nondemocracy, add to our understanding of media manipulation and authoritarian endurance.
A Comprehensive Analysis and prognostication of COVID-19 (SARS-Cov-2) Outbreak situation in India
Authors: sahoo satyabrata
Published: June 2021

Covid-19 is an infectious respiratory disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), first identified in late December 2019 in China and later spread worldwide. The first case of Covid-19 was diagnosed in the last week of January 2020, India. Subsequently, the number of cases drastically rose. As of May 11, 2021, in India, 2,33,40,375 positive cases have been reported, out of which 1,93,76,561 recovered and 2,53,634 death were reported as per covid19india report. To avail in designing better strategies and in making effective decisions, we can use forecasting techniques. These techniques assess the past situation, thereby enabling better prognostications about the situation to occur in the future. Based on these time series modeling, this paper tries to study the prediction of Covid-19 in terms of total substantiated, recovered, and death cases. It also examines the daily infected, active, recovery, and death cases. The correlation coefficients and sarimax forecasting model were applied for prediction and statistical measures used for population variance equality.
TEARS OF BLOOD AND RAIN $ USD IN INDONESIA (Covid19 Case Study 2020-2021)
Authors: naryono endang
Published: June 2021

Humans can only try but God is the one who decides, when the government is full of optimism with economic growth which since 2016 – 2019 has been sharply corrected not in line with expectations, although many doubt it because it is too dreaming in the midst of the world's economic downturn and macro and micro indicators that are not supportive . At the end of 2019 the world was shocked by a humanitarian disaster, namely Covid-19 which started from Wuhan, China and spread throughout the world. Many observers say that Covid19 has spread to Indonesia but the government denies it and many ministers underestimate it and even make it a very unfunny joke.It was only on March 2, 2020 that the government announced that Covid19 had entered Indonesia. The government began to panic especially the people, people stormed shopping centers so that basic commodities became scarce even if they were available, the prices were very expensive, health products disappeared from the market because there were many inappropriate purchases and many people hoarded them in the hope of getting high profits. The government seems to be in a dilemma between the economy or the safety of its people, both of which are very important, especially since Indonesia's economic growth is largely influenced by public consumption.Now that we have entered the second year of Covid19, there are no signs that mean that covid19 will disappear in the world and especially in Indonesia on June 10-16, 2021, the surge affected by Covid19 is getting crazier, even as if it is out of control at the athlete's house in Jakarta, the occupancy is approaching 80%. has exceeded the limits set by the WHO, West Java, Central Java and East Java. The higher spike makes people more nervous and makes it more difficult to survive.
Nanobiosensing with target amplification, and nanoswimmers can be controlled by magnetic fields and facilitate gene therapy and nanomedicine applications
Authors: Dowaidar Moataz
Published: June 2021

Nanobiosensing with target amplification is one such example. In this scenario, "activator" nanoparticles stimulate the target location, such as a tumor, resulting in spatial amplification of a tumor-triggered phenomenon-of-interest (POI). The typical targeting approach, which relies on the human vascular system to transport nanoparticles, is inefficient and is considered a brute-force search from a computing standpoint. By evaluating the observable properties of these nanoswimmers, which are controlled by magnetic fields created by electromagnetic coils, an external tracking system is utilized to explore the tissue environment. The stochastic movement of numerous loosely connected, disc-shaped components in the system results in deterministic locomotion. When each component is programmed to oscillate omnidirectionally along its radius, expanding and contracting in response to varying environmental signals, the system can collectively locomote towards the source of the environmental signal. The main goal is to enable interoperability while developing multiple simulation components for computational nanobiosensing with different and non-interoperable interfaces. The accuracy of the computational models and algorithms should be tested utilizing multi-physics in silico platforms that simulate the targeting of externally manipulable or self-regulatable nanorobots. To minimize the rates of erroneous and missed detection, "natural" deep learning approaches might be used to train mathematical models for in vivo target identification. The particle stretching approach for creating worm-like structures capable of low-Reynolds-number propulsion when actuated by a rotating magnetic field is one possibility. To replicate the function of an MRI, a sensor array made up of several magnetoresistive sensors might be utilized to precisely place nanorobots. Such systems would also need to be developed in three dimensions, with more complicated locomotive behavior of components and aggregates inside blood flows. In conclusion, computational nanobiosensing is to improve in vivo POI targeting and understanding of POI-induced gradients.
Rotational Ground Motion Measurements for Regional Seismic Moment Tensors: a Review
Authors: Donner Stefanie
Published: June 2021

Seismic moment tensors are an important tool in geosciences on all spatial scales and for a broad range of applications. The basic underlying theory is established since decades. However, various factors influence the reliability of the inversion result, several of them are mutually dependent. Hence, a reliable retrieval of seismic moment tensors is still hampered in many cases, especially at regional event-receiver distances.To sample the entire wavefield due to a seismic source we need six components: three translational and three rotational ones. Up to now, only translational ground motion recordings were used for moment tensor retrieval, missing out valuable information. Using rotational in addition to the classical translational ground motions during waveform inversion for moment tensors mainly adds information on the vertical displacement gradient to the inversion problem. Furthermore, having available six instead of only three components per receiver location provides additional constraints on the sampling of the radiation pattern. As a result, the moment tensor components are resolved with higher precision and accuracy, even when the number of recording receivers is considerably reduced. Especially, components with a dependence to depth as well as the centroid depth can benefit significantly from additional rotational ground motion. Up to the time of writing this review only a few studies are published on the topic. Here, I summarise their findings and provide an overview over the possible capabilities of including rotational ground motion measurements to waveform inversion for seismic moment tensor retrieval.
So What? Implications of Network Theory for Research and Practice
Authors: Jones Payton J. , Robinaugh Donald
Published: June 2021

Research and practice in psychiatry and clinical psychology have been guided by differing schools of thought over the years. Recently, the network theory of psychopathology has arisen as a framework for thinking about mental health. Network theory challenges three assumptions common in the field: (1) psychological problems are caused by disease entities that exist independently of their signs and symptoms, (2) classification and diagnosis of psychological problems should follow a medical model, and (3) psychological problems are caused by diseases or aberrations in the brain. Conversely, it embraces many other assumptions that are already well accepted in clinical practice (e.g., the interaction of thoughts, behaviors, and emotions, as posited in cognitive-behavioral therapies) and integrates those assumptions into a coherent framework for research and practice. We review developments in the network theory with a focus on anxiety-related conditions, discuss future areas for change, and outline implications of the theory for both research and clinical practice.
Do Media Objectivity and Frequency of Informing Mediate the Relationship Between Traditionalist Social Attitudes and COVID-19 Conspiracy Beliefs?
Authors: Karić Tijana , Međedović Janko Mileta
Published: June 2021

In this study, we hypothesized that traditionalist social attitudes (conservatism, religiousness, and authoritarianism) significantly predict COVID-19 conspiracy beliefs (Hiding Information and Harmless Virus), as well as conspiracy mentality in general. We also hypothesized that these relationships are mediated by the objectivity of the media through which individuals inform themselves, and the frequency of informing. The sample consisted of 341 participants from Serbia (mean age 33.51 years), of which 40.5% were women. The results revealed that conservatism predicts both conspiracy belief sets and conspiracy mentality, authoritarianism only COVID-19 conspiracy beliefs, and religiousness only beliefs that the virus is harmless. Media objectivity does not mediate these relationships. The frequency of informing is a significant mediator only of the relationships between authoritarianism, and conspiracy beliefs and conspiracy mentality, indicating that the role of seeking information is in reducing the threat perceived by more authoritarian individuals. The study reveals that media objectivity might not play a role in reducing conspiracy beliefs. An explanation might be found in the importance of the perceived credibility of the media.
Far from the eyes, far from the heart. COVID-19 confinement dampened sensitivity to painful facial features.
Authors: Antico Lia , Corradi-Dell'Acqua Corrado
Published: June 2021

In the last two years, governments of many countries imposed heavy social restrictions to contain the spread of the COVID-19 virus, with consequent increase of bad mood, distress, or depression for the people involved. Few studies investigated the impact of these restrictive measures on individual social proficiency, and specifically the processing of emotional facial information, leading to mixed results. The present research aimed at investigating systematically whether, and to which extent, social isolation influences the processing of facial expressions. To this end, we manipulated the social exclusion experimentally through the well-known Cyberball game (within-subject factor), and we exploited the occurrence of the lockdown for the Swiss COVID-19 first wave by recruiting participants before and after being restricted at home (grouping factor). We then tested whether either form of social segregation influenced the processing of pain, disgust or neutral expressions, across multiple tasks probing access to different components of affective facial responses (state-specific, shared across states). We found that the lockdown (but not game-induced exclusion) affected negatively the processing of pain-specific information, without influencing other components of the affective facial response related to disgust or broad unpleasantness. In addition, participants recruited after the confinement reported lower scores in both empathy questionnaires and affective assessments of Cyberball co-players. These results suggest that social isolation affected negatively individual sensitivity to other people’s affect and, with specific reference to the processing of facial expressions, the processing of pain-diagnostic information.

Published: June 2021

We present a computerize battery constructed to evaluate behavioral performances for language, declarative memory, executive functions and social cognition abilities. This battery was created to evaluate cognitive outcomes in adults who underwent hemispherotomy as a clinical treatment of Rasmussen Encephalitis (RE) in their childhood and have been tested in a group of healthy participants (n= 88). LEXTOMM battery can be used for cognitive assessment of any type of population and allow the collection of behavioral performances in terms of accuracy and reaction times. LEXTOMM battery is composed of six language tasks allowing to assess six different linguistic abilities such as lexical storage, semantics, phonology, syntax, prosody perception and production. Different input modalities are proposed for these tasks (picture, written and auditory modality). A specific task allowing the assessment of the language generation and declarative memory interaction is also proposed. The battery also included a visual control categorization task is proposed in order to assess decision-making baseline. Moreover, LEXTOMM also includes four tasks allowing the assessment of the executive functions. More specifically we included tasks allowing the evaluation of four executive processes: updating in working memory, switching/flexibility, sustained attention and inhibition. Finally, the battery includes a theory of mind abilities task. All tasks were developed using the E-Prime 3.0 software (E-Prime Psychology Software Tools Inc., Pittsburgh, USA), running on a PC. Before each task, a training session is included, with several stimuli that differ from those presented during the experiment. This training allows participants to understand the instructions and get familiarized with each task. Hereafter, we describe the procedures and tasks included in LEXTOMM, in the following order: low-level visual categorization, language, language in interaction with declarative memory, executive functions and social cognition/theory of mind.
A Feminist Scheme Conveyed through Catherine Jemmat’s The Rural Lass
Authors: Almufayrij Haifa
Published: June 2021

This study analyses The Rural Lass by Catherine Jemmat (1714-66); the poem will shine a new light on a feminist agenda conveyed through Jemmat’s views through the persona of the rural lass by linking the lass’ own experience with marriage. Challenges in a patriarchal society among female poets in the early ages and before the twenty-first century deserve appreciation for their contributions to early feminist literature. The author will illustrate how Jemmat negotiated her ambitions despite the cultural restrictions that were placed upon her during the 18th century through a rural persona. Jemmat skillfully creates a light-hearted poem, but also one that reflects the determined voice of a speaker who refuses to allow others to dictate her life. Jemmat seems to achieve this in The Rural Lass, as she subtly challenges the parental and societal objections that could often, as in Jemmat’s case, prevent the marriage of a loving couple. This article will study through the feminist literary criticism, that closer analysis of the variations within the metrical composition and of the poetic features in The Rural Lass shows that a deeper level of meaning can be achieved. The structured reasoning ensures that the rural lass appears rational and justly defiant. This paper also explores how a close study of the text allows for the emergence of the admirable spirit of the figure of the rural lass that expresses challenges in a patriarchal society, an eighteenth-century British feminist that has been criticized by her community.
The Value of Intertextuality in Selvon’s The Lonely Londoners and Naipaul’s The Mimic Men
Authors: Mzoughi Imen
Published: June 2021

Studies on comparative literature have been fragmentary concentrating on one or two aspects of the thematic concerns of novels without emphasizing the concepts of divergent and convergent intertextuality. This paper aims to revisit Selvon’s The Lonely Londoners re-reading it in dialogue with Naipaul’s novel The Mimic Men. The selected novels are controversial. Criticism deployed on all fronts conveys the pluralities and oppositions that are in fact the novels’ hallmarks. Yet, the aspects criticized attest to, and confirm, the authors’ taking of the less trodden track. The comparative analysis within the scope of this paper will show that Naipaul’s and Selvon’s fictional representations of creolized Trinidadian and English societies highlight specific cultural and linguistic aspects and that intertextuality is either convergent or divergent. For instance, the structure of Naipaul’s text takes as much from Caribbean orature and the wake of Caribbean plantation culture. However, Selvon’s novel takes the form of flashbacks. Naipaul innovates and transforms Selvon’s structure to generate a Caribbean context, par excellence. Traces of Selvon’s style are present in Naipaul’s corrosive voice of representing Caribbean identity. Naipaul brings to an apotheosis the creative force already illustrated in the remarkable works of Selvon. This paper aims to track these traces and foreground the idea that texts can speak to each other. More significantly, this paper assesses the main characters’ fates to re-question the status of creoles, a status deliberately put between parentheses, denying them the right to voice their hybrid identities. Above all, the close textual reading of Galahad’s and Singh’s stories is meant to value the trope of intertextuality.
Review of Competition Law on Tariffs Lower Limit Indonesian Airlines
Authors: Tarina Dwi Desi Yayi , Haryanto Imam
Published: June 2021

The price policy is an inseparable part of business competition. The price policy is not solely related to efforts to maintain prices or even control prices at a certain level but is an effort to generate profits that are proportional to social welfare. Since the entry of business competition regulations in Indonesia, with the increase in airline business actors, the competition between them has become more profitable for consumers. With high competition and competitive prices, airlines, especially national airlines, show that the target of this airline is the middle market share. In this paper, we will discuss the determination of the lower tariffs for air transportation issued in the Regulation of the Minister of Transportation of the Republic of Indonesia and regarding its application and impact on consumers and business actors in the aspect of business competition. Research result The stipulation of the lower limit rate stipulated in the Regulation of the Minister of Transportation Number 14 of 2016 is basically against the provisions of the business competition law, particularly about the prohibition on price-fixing as regulated in Article 5 Paragraph (1) of Law No. 5/1999. The effect of Regulation of the Minister of Transportation Number 14 of 2016 on airline business actors and consumers, among others, is that the freedom of business actors to determine their fares is reduced, this results in not achieving price efficiency.

Real-time Web Search Framework for Performing Efficient Retrieval of Data
Authors: Al-akashi Falah , Inkpen Diana
Published: June 2021

With the rapidly growing amount of information on the internet, real-time system is one of the key strategies to cope with the information overload and to help users in finding highly relevant information. Real-time events and domain-specific information are important knowledge base references on the Web that frequently accessed by millions of users. Real-time system is a vital to product and a technique must resolve the context of challenges to be more reliable, e.g. short data life-cycles, heterogeneous user interests, strict time constraints, and context-dependent article relevance. Since real-time data have only a short time to live, real-time models have to be continuously adapted, ensuring that real-time data are always up-to-date. The focal point of this manuscript is for designing a real-time web search approach that aggregates several web search algorithms at query time to tune search results for relevancy. We learn a context-aware delegation algorithm that allows choosing the best real-time algorithms for each query request. The evaluation showed that the proposed approach outperforms the traditional models, in which it allows us to adapt the specific properties of the considered real-time resources. In the experiments, we found that it is highly relevant for most recently searched queries, consistent in its performance, and resilient to the drawbacks faced by other algorithms

ΔRLE
Authors: Mados Branslav , Bilanová Zuzana , Hurtuk Ján
Published: June 2021

Lossless data compression algorithms can use statistical redundancy to represent data using a fewer number of bits in comparison to the original uncompressed data. Run-Length Encoding (RLE) is one of the simplest lossless compression algorithms in terms of understanding its principles and software implementation, as well as in terms of temporal and spatial complexity. If this principle is applied to individual bits of original uncompressed data without respecting the byte boundaries, this approach is referred to as bit-level Run-Length Encoding. Lightweight algorithm for lossless data compression proposed in this paper optimizes bit-level RLE data compression, uses special encoding of repeating data blocks, and, if necessary, combines it with delta data transformation or representation of data in its original form intending to increase compression efficiency compared to a conventional bit-level RLE approach. The advantage of the algorithm proposed in this paper is in its low time and memory consumption which are basic features of RLE, along with the simultaneous increase of compression ratio, compared to the classical bit-level RLE approach.

In the paper, we consider non-classical queueing systems with non-homogeneous customers. The non-homogeneity we treat in the following sense: in systems under consideration, we characterize each customer by random capacity (volume) that can have an influence on his service time. We analyze a stochastic process having the sense of the total volume of all customers present in the system at given time instant. Such analysis for different queueing systems with unlimited or limited total volume can be used in designing of nodes of computer and communication networks while determining their buffer space capacity. We discuss basic problems of the theory of these systems and their performance characteristics. We also present some examples and results for systems with random volume customers

The development and use of information and communication technologies (ICTs), and in particular the Internet, have changed the way businesses operate in the last twenty years, providing a number of new opportunities for improving innovation and competitiveness. Today, modern ICT is considered to be the basis for the development of a knowledge society, in which the concept of e-government plays a special role. The main goal of this paper was to examine the perceptions of business users, in terms of perceived barriers and benefits achieved, from the use of electronic public administration services. The survey included 500 companies with the highest business income in Serbia. The data collected were analyzed using Pearson’s correlation coefficient, Mann Whitney’s test and Kruskal-Wallis test. The results of the research showed that the level of acceptance of electronic services is still lower than expected, given the volume of services offered. Also, this study pointed to the need to raise the level of awareness of businesses about e-government services, as well as the need to improve the quality of electronic services, in terms of complete digitization, alignment with enterprise requirements and regular updating of data.

Solanum lycocarpum A. St-Hil (wolf’s fruit or lobeira) (Solanaceae) is a perennial shrub typical of the Brazilian Cerrado (savanna), under constant cutting and burning due to anthropic activities for the development of agricultural and livestock farming. It presents therapeutic medicinal attributes for humans and wild animals primarily as an anthelmintics. Little is known about the insect fauna associated with S. lycocarpum, and no study has been conducted on the true bugs (Heteroptera) associated with it. For the study, the true bugs were sampled from ten points in the mesoregion of Triangulo Mineiro and Alto Paranaiba for one year in two seasonal periods of drought and rain. In each locality, 20 shrubs of S. lycocarpum were selected.

Providing the population with food, agriculture with planting material, and raw materials for the processing and canning industries is an urgent problem of garlic production. Currently, not studied yet the passage and changes in the production processes of garlic plants under the influence of reproduction, which in some way constrains the industrial production of planting material and marketable products in general. Studies on the impact of reproductions on changes in physiological state, plant resistance to disease and productivity were conducted during 2017–2020 in the research field of the Department of Vegetable Growing, Uman National University of Horticulture. During the biometric measurements, a significant change in the variation of approbation traits (height of the plant and scape, number of leaves and its size, number and weight of bulbils, cloves in the bulb) of garlic plants under the influence of reproduction, ie variety testing must indicate what is this generation. There was a significant decrease in the concentration of chlorophyll and the antioxidant enzymes activity in the leaves in III–V reproductions, which significantly affected the productivity and tolerance of plants. Indicators of plant damage disease on a natural infectious background indicated a sharp decrease in the resistance of plants of the Sofiivskyi cultivar in IV–V reproductions, Prometei and Lyubasha cultivarss in III–V. It was found that in the cultivar Sofiivskyi the largest mass of the bulb was formed in the first reproduction, while in the cultivars Prometheus and Lyubasha – in the second, and its gradual decrease to 21.2 % in the fifth reproduction. Yield had a similar trend, where the maximum reduction in yield was observed at 18.2; 28.0 and 17.0 % in the cultivars Sofiivskyi, Prometei and Lyubasha. The developed scientifically substantiated provisions will allow to increase efficiency of selection process and production of seed material.

One of the effective ways of creating high-yield tobacco varieties is the selection of donors of economically valuable characters and their optimal combination in new plant genotypes. Sources for selection and creation of such donors are gene pool collections, which concentrate source material of different geographical origin with a set of valuable breeding and genetic characters. The level of expression of these characters is modified by breeding conditions and the response of the genotype to environmental factors. Therefore, the main purpose of our research was to study the manifestation of morpho-biological features and properties of plants of tobacco collection samples in agroclimatic conditions of the Central Forest-steppe of Ukraine, establishment of breeding value of available gene pool of culture, selection of sources of economically valuable characters and formation of working tobacco collection. The strategic task of research is to create the varieties that are able to maximize the use of their genetic potential in a specific region, to be resistant to stressful environmental conditions, to ensure a high realization of the genetic potential of productivity. For the first time in the conditions of the Central Forest-steppe of Ukraine the analysis of 30 collection samples of tobacco of different ecological and geographical origin was carried out. New genetic sources for morphological character of plants, raw yield, seed productivity and early maturity, which are used at the Experimental station of tobacco farming National Research Center "Institute of Agriculture of the National Academy of Agrarian Sciences" in variety breeding, were identified. A certificate of registration of the working collection of tobacco gene pool of the present on morphological characters was received from the National Center for Plant Genetic Resources of Ukraine, according to the results of research in 2017–2019 (Certificate № 277 from 29.10.2019).
