Poder e Autonomia: As Assimetrias do Sistema Financeiro e Monetário Internacional
Authors: Carneiro Gabriel Santos
Published: September 2020

Este artigo tem por objetivo explicitar a natureza assimétrica das relações financeiras e monetárias entre os Estados desde 1945 até o presente. Destaca-se que as decisões tomadas acerca das questão financeiras internacionais foram marcadas pelo unilateralismo dos Estados Unidos, de forma que o poder, tratado em termos de autonomia, se mostrou fator decisivo e explicativo das mudanças financeiras internacionais. Assim, o sistema financeiro internacional é caracterizado por uma discrepante autonomia norte-americana em relação aos demais países, de maneira que esse sistema é moldado fundamentalmente a partir dos interesses dos Estados Unidos, enquanto que aos demais Estados restam as consequências, em larga medida desfavoráveis, das opções escolhidas. O artigo, com o objetivo de casar a teoria com a história, focará em dois eventos específicos: a crise da libra esterlina de 1947 e a crise da dívida dos países latino-americanos da década de 1980, buscando sempre mostrar como que as ações norte-americanas acabam por prejudicar e afetar negativamente os demais Estados que carecem de autonomia para resistirem às influências externas. 

This article aims to explain the asymmetric nature of financial and monetary relations between States since 1945 until nowadays. It is highlighted that the decisions made on the international financial matters are characterized by the unilateralism of the United States, in a way that power, seen here as autonomy, has proven to be a decisive and explanatory element of the international financial changes. Thus, the international financial system is characterized by a discrepant North-American autonomy compared to other countries, so that this system is fundamentally forged under the interests of the United States, whereas the consequences from the chosen choices, which are mainly negative, are left for the other countries. The article, intending to match theory with history, will focus in two specific events: the 1947’s sterling crisis and the 1980s external debt crisis of the Latin-American countries, looking forward to demonstrate how the North-American actions impaired and undermined the other countries that lack autonomy to resist external influences.
A porta fechou, o perigo passou, o shopping-trem chegou
Authors: De Toledo Giovanna Pompêo , Pintor Vinícius
Published: September 2020

O presente trabalho se propõe a apresentar hipóteses acerca do comércio ilegal que ocorre na Companhia Paulista de Trens Metropolitanos, popularmente conhecido “shopping-trem”, no que se refere ao comportamento e relações constituídas entre vendedores e guardas. Expõe-se a ideia de que os agentes do Estado na verdade gerem a atividade delinquente ao invés de combatê-la. Também houve interesse em investigar quais identidades são performadas pelos sujeitos inseridos dentro dessa lógica de vendas irregulares. Uma cooperação mútua entre os ambulantes ilegais, códigos e regras para se vender seus produtos, além de discursos e práticas regulares desempenhadas foram encontradas. No que se refere à identidade do próprio espaço, por característica inerente a si tão fluído e móvel, apropriou-se da teoria de Marc Augé para se propor que os trens são espaços sobrepostos, “lugares” para os comerciantes e guardas, “não-lugares” para passageiros.
A fome na exclusão social de São Paulo nos anos 2000
Authors: Cruz Arquias Sófocles Guimarães Soares
Published: September 2020

A fome é um problema social que atinge a milhões de pessoas no Brasil, porém, muitas vezes, faltam discussões sobre a sua dimensão política no contexto histórico latino-americano. A partir de uma perspectiva decolonialista, o artigo abordou uma breve análise da relação entre a exclusão social e a fome no Estado de São Paulo na década de 2000. Buscou-se discutir sobre alguns fatores políticos relevantes para o entendimento da fome como um processo social, como a colonialidade do poder na América Latina. Concluiu-se que há padrões semelhantes no comportamento dos dados e que há a recorrência de alguns temas, como as desigualdades de gênero e racial, apesar dos índices gerais terem apontado avanços sociais durante a década.
Os Direitos autorais na era digital

Published: September 2020

O presente artigo tem o objetivo de analisar os direitos autorais após a expansão da internet e as possíveis implicações dos artigos 11 e 13 da nova Diretriz de Direitos Autorais da União Europeia para a criação de conteúdo digital. Para isso, contextualiza-se a abordagem teórica dos direitos autorais, a popularização do YouTube, os aspectos da nova Diretriz de Direitos Autorais da União Europeia e os seus controversos artigos 11 e 13, analisando suas implicações para a criação de conteúdo digital e na plataforma do YouTube. Por fim, conclui-se que o prosseguimento da implementação de tais artigos no contexto europeu teria profundas consequências, tanto para a plataforma, quanto para os criadores de conteúdo e para a sociedade em geral, visto que representam uma contradição à liberdade de expressão, acesso à informação e cultura e ao desenvolvimento criativo.
Research note: The spread of political misinformation on online subcultural platforms
Authors: Burton Anthony G. , Koehorst Dimitri
Published: September 2020

This research note explores the extent to which misinformation and other types of “junk” content are spread on political boards and forums on 4chan and Reddit. Our findings suggest that these userbases are impervious to the appeal of low-quality “pink slime” news sites with algorithmically generated conservative talking points masquerading as journalism. However, these political boards' reliance on YouTube as a news source—specifically a group of ideologically-charged, misinfor-mation-laden channels that are part of what has been called the “Alternative Influence Network”—shows that cross-platform movements must be factored in to studying the spread of misinfor-mation. In addition, this study illustrates the viability of cross-platform hyperlinks as an object of study to better understand how users on particular platforms interact with the web at large.
INTELLIGENT LOAD CONTROL SYSTEM FOR 10 \ 0.4 KV TRANSFORMERS USING SCADA
Authors: Vidmysh Andriy , Tokarchuk Oleksii , Karpiychuk Michael , Paladii Maksym
Published: September 2020

The article proposes a system of control of load of the power transformer on the basis of monitoring of the basic operating parameters of the distributive power transformer. Overloads, voltage fluctuations and heating create conditions for potential damage to transformers, which takes a long time to maintain and costly. The system is designed to provide basic information on DPT status. The system uses this data to optimize DPT performance and avoid possible emergencies. The monitoring system provides a simple enough toolkit to overcome abnormal operating modes - from minor deviations to the most catastrophic failures. Load monitoring is carried out by the use of sensory devices in the power supply system. Methods of finding and equipment of monitoring points are proposed. SCADA data - load levels, temperature levels and voltages - are fed through a series of digital communication channels to the master controller for immediate action. A practical scheme has been developed that tracks and collects basic parameters such as winding current, oil level and DPT temperature. A topology has been developed, taking into account the expected loads to provide uninterrupted power to consumers. To ensure constant power supply to consumers, power transformers with a multi-winding configuration are used. Therefore, during the surges of consumer loads, constant supply is ensured without damaging the transformers. The distribution system is also open for diagnostic control. The scheme of the microcontroller interacting with a circle of the communication device is offered. Load monitoring is also a particular concern, as consuming excess power is an economic burden. Load imbalances, misuse of electricity, overloads or short circuits, harmonic problems, voltage profiles, power factor and minor problems can all be detected by this system.
ANALYSIS OF METHODS OF WASHING FOOD VEGETABLE RAW MATERIALS
Authors: Gladushnyak Oleksandr , Vsevolodov Oleksandr
Published: September 2020

The article is devoted to the issues of rational consumption of clean water for carrying out the technological process of washing vegetable raw materials, as well as finding out the reasons for the high energy costs of the technological process of washing. The requirements of state standards that are presented to raw materials supplied to canning enterprises for the processing and production of canned foods are described. The amount of soil contamination and the number of microorganisms that are allowed by the relevant standards on the surface of root crops are indicated. It also indicates the inadmissibility of using water that does not meet the requirements of the standards. The modern equipment of the world leading manufacturers of equipment for washing plant materials and some domestic manufacturers is considered. The main directions of using clean water for the technological process of washing vegetable raw materials are considered. The amount of clean running water used for washing is indicated, which on average exceeds 1.5 ... 2 times that accepted in industry. The characteristics of some modern washing machines are given, the reasons for the increased clean water consumption, as well as the drive power of the washing machines, are described. The average value of specific electricity consumption per 1 kg of washed raw material is given. To solve the issues of rational consumption of clean running water, as well as reducing power to drive washers, a technological process that uses a two-stage washer with a section of "dry washing" of vegetable raw materials is proposed. By coordinating the washing regimes in the two-stage method, it is possible to significantly reduce both the flow rate of clean running water and the energy consumption for the washing process of raw materials. The article shows a diagram of a universal two-stage washer for washing plant materials, in particular root crops.
The proposed method and design of the machine that implements this method are protected by the patent of Ukraine No. 107488 for the invention.
SUBSTANTIATION OF THE CONSTRUCTIVE-TECHNOLOGICAL SCHEME OF THE CAVITATION DISPERSATOR-HOMOGENIZER OF AGRICULTURAL RAW MATERIALS OF PLANT ORIGIN FOR FODDER PURPOSES
Authors: Aliyev Yelchin , Mykolenko Svitlana , Yaropud Vitaliy , Malegin Roman
Published: September 2020

n urgent task is to increase the efficiency of preparation of high-quality feed through the use of technological processes of dispersion and homogenization with cavitation processing of feed components. The aim of the research is to substantiate the constructive-technological scheme of cavitation dispersant-homogenizer of agricultural raw materials of plant origin for feed purposes. As a result of research, the design of the working bodies (rotor and stator) of the cavitation dispersant-homogenizer was proposed and justified. Structurally, stator resonators and rotor confusers at the moment of their comparison form blades, the curvature of which repeats the curvature of the impeller of a centrifugal pump. To verify the operation of the proposed working bodies of the cavitation dispersant-homogenizer, numerical simulation was performed using the Star CCM + software package. Modeling was carried out using the model of multiphase interaction, Eulerian multiphase, volumetric fluid method (VOF). The phase motion obeys the k-ε turbulence model. At the first, the approximate mixture was presented as a two-phase liquid-gas medium, while the gas is the gaseous phase of the liquid. The thermodynamic state of the mixture was allowed as a resolving multiphase temperature. It was assumed that the liquid in the process of movement had a constant density, and the gas was ideal. The interaction between the liquid-gas phases obeyed the VOF-VOF bulk fluid and Schnerr-Sauer cavitation models. As a result of numerical simulation of the cavitation dispersion process on the developed design, its effectiveness is proved as a pump for pumping liquids with components of the feed mixture, as well as a grinder using a hydro-shock, which is formed as a result of cavitation in the stator resonators and rotor confusers.

Published: September 2020

Melon and watermelon are two high-value crops that have been commercially cultivated recently inSoutheast Sulawesi. The objective of the study was to examine and compare the cost and returns of melon andwatermelon production. The study was conducted in Abenggi village in South Konawe district of SoutheastSulawesi. Twenty melon farmers and 20 watermelon farmers were selected as respondents. Data collection wasdone using a questionnaire-based interview method. Data and information were analyzed using cost and returnsanalysis and independent sample t-test. Results of the study revealed that both melon and watermelonproduction were profitable as indicated by their revenue-cost ratio being higher than 1. Due to small size offarming, difference in net returns per farm from melon and watermelon was not statistically significant. Perhectare net returns from melon farming were statistically significantly higher than that of watermelon farming.Net returns from either melon or watermelon farming were higher than that of many other crops in theprovince. Farmers should continue to focus on the cultivation of the crops as they can increase their income andpromote rural economy. The local government should assist the development of the two crops by ensuringavailability of farm inputs and improving provision of weather forecast results to the farmers.

Authors: ABDUR RAZZAQ MD. , ISLAM TARIKUL
Published: September 2020

The structural, mechanical, electronic and optical properties of double perovskite Cs2SnBr6 have been measured by density functional theory (DFT) calculations. The calculated value of lattice parameter is perfectly tailored with the experimental data. The material shows ductile behavior by Paugh’s ductility index (B/G) at ambient condition. The anisotropic nature of this compound is endorsed by the calculation of Zener anisotropy factor. The direct band gap semiconducting nature with the value of gap is 1.33 eV using PBE potential is also corroborated by electronics properties. Eventually, different optical properties of Cs2SnBr6 such as dielectric constants, refractive index, conductivity, absorption, reflectivity and loss function have been observed and disclose for radiation up to 20 eV. Finally the optical properties corroborate the optoelectronic applications of this compound as all as elite candidate for photovoltaic perovskite solar cells.
Are small additions solved by direct retrieval from memory or automated counting procedures? A rejoinder to Chen and Campbell (2018)
Authors: Thevenot Catherine , Barrouillet Pierre
Published: September 2020

Contrary to the longstanding and consensual hypothesis that adults mainly solve small single-digit additions by directly retrieving their answer from long-term memory, it has been recently argued that adults could solve small additions through fast automated counting procedures. In a recent article, Chen and Campbell (Psychonomic Bulletin & Review, 25, 739–753, 2018) reviewed the main empirical evidence on which this alternative hypothesis is based, and concluded that there is no reason to jettison the retrieval hypothesis. In the present paper, we pinpoint the fact that Chen and Campbell reached some of their conclusions by excluding some of the problems that need to be considered for a proper argumentation against the automated counting procedure theory. We also explain why, contrary to Chen and Campbell’s assumption, the network interference model proposed by Campbell (Mathematical Cognition, 1, 121–164, 1995) cannot account for our data. Finally, we clarify a theoretical point of our model.

The Exotic Other and the Other Within
Authors: Kurenbach Anton , Niederhoff Burkhard
Published: September 2020

A. C. Doyle praised R. L. Stevenson’s tale The Pavilion on the Links as »the high-water mark of his genius«. He also imitated it very closely in one of his own tales, The Mystery of Cloomber. The present article details the many parallels between the two texts. It also analyses the remaining differences, which are primarily related to the role played by a group of foreigners. Doyle exoticises the foreigners, representing them as Eastern mystics whose mental powers are infinitely superior to those of the British characters. By contrast, Stevenson’s foreigners are ordinary mortals. They are not strange or exotic in themselves; they rather act as a catalyst of strange, incongruous and surprising elements in the personalities of the British characters.
Lo sguardo sugli Ebrei, lo sguardo degli Ebrei nelle testimonianze di sopravvissuti al campo di concentramento di Mauthausen
Authors: Kuon Peter
Published: September 2020

This article examines the self-perception of Jews and the perception by others in a concentration camp that was not built for the genocide of European Jews, but for the gradual extermination of domestic and foreign opponents of the regime through forced labour and malnutrition. How did the survivors remember the presence of Jews in a camp for political prisoners? Which factors determined positive and negative judgments? How did the Jews, who constantly feared being discovered and murdered, perceive themselves in relation to the majority of the others? The study is based on autobiographical texts in French by forty-eight French survivors of the Mauthausen concentration camp and five Eastern European Jews who emigrated to France after the war.
›Deutsch-muslimische‹ Lyrik?
Authors: Löffler Jörg
Published: September 2020

Zehra Çırak (born 1960) and Zafer Şenocak (born 1961) are authors of German-Turkish origin, who are especially renowned for their poems. Apart from intercultural issues, questions of religion and disbelief can be found in their large output of poems, fiction and essays. Şenocak’s long poem Geschrieben auf Stein und Knochen (1994) is about faith and scepticism in the three monotheistic religions as well as in Marxism as a secular system of beliefs. Something similar is true of Çırak’s poem Konfessionen (1991), which is about religious ritual and sectarianism as having restrictive effects on individual liberty. With a keen eye on both Eastern and Western spiritual traditions, these two poets explore the dialogue between Islam, Judaism and Christianity – from a secular perspective, but with a great interest in the prevailing power of religious sentiment in contemporary culture.
Vergil und das Epische Erzählen
Authors: Kragl Florian
Published: September 2020

The article discusses Jan-Dirk Müller’s concept of ›epic narration‹ with respect to the dominant Virgilian tradition during the Middle Ages. Müller’s ›epic narration‹ is defined as a quasi-autochthonous vernacular mode of medieval, (at least seemingly) archaic narration, strictly distinct from the, so-to-speak, Virgilian world of the litterati, and closely resembling everyday conversation: ›Epic narration‹ is narration in the presence of narrator and audience; it unfolds common narrative knowledge; the narrated past and the presence of narration are closely intertwined; what is told, is simply true; time and space are organized primitively via deictic markers; the themes are, even if Müller somewhat skips that point, martial and belligerent.
The article argues that Virgil’s Aeneid is no counterpart to that mode of ›epic narration‹, but that it participates in this more or less universal concept, albeit as its most sublime refinement. Virgil overcomes primitive ›epic narration‹ artistically by means of an unrivalled poetic perfection. This particular observation on the Aeneid poses severe questions to literary history. Even the vernacular poems offer no ›pure‹ ›epic narration‹, and Virgil’s epic in particular (as well as the Latin tradition in general, including Servius, Statius, Ovid etc) was most likely known to (most of the) vernacular poets. Hence, the idea of vernacular autonomy appears highly problematic. To put it bluntly, is the ›epic narration‹ of medieval literature an autochthonous vernacular mode, or does it, like so many other things, sprout in the long shadow of the Aeneid? Reflecting Müller’s ›epic narration‹ from a Virgilian perspective inevitably provokes a profound revision of medieval literary history.
Politik und Poetik
Authors: Jostkleigrewe Georg
Published: September 2020

The article examines the relationship between ›literature‹ and ›politics‹; it focuses on medieval poetry that was produced in the context of partisanship and factional strife. Such texts, it is argued, must not be analysed in a purely ›literary‹ approach – nor in a purely historical one either. Instead, we should study these works from a double perspective which accounts for both their political functions and their artistic character – thus producing closer insights into the literary qualities as well as the historical significance of the respective texts. The article illustrates these general reflections by a close reading of several poems written by Rutebeuf (floruit ca. 1250–1280) in the context of the so-called Mendicant controversy at the University of Paris. It first discusses the short-comings of Michel-Marie Dufeil’s historico-biographical reading of the poems in question. In a second step, it argues that we cannot reasonably understand Rutebeuf’s polemics as a kind of ›autotelic‹ literary play (as proposed by Claudio Galderisi) either. Instead, the article tries to situate Rutebeuf’s poems in different echo chambers which dominate the public sphere of the 13th-century French kingdom – thus producing a fresh look on various intertextual references which have hitherto passed unnoticed.

Forecasting Zambia’s Gross Domestic Product Using Time Series Autoregressive Integrated Moving Average (ARIMA) Model
Authors: Sankwa Chikumbe Evans , Sharper Sikota
Published: September 2020

Gross Domestic Product is one of the social indicators of development. This study attempts to model Zambia’s Gross domestic product using the Autoregressive Integrated Moving Average (ARIMA) model. This model has proved to help many countries during economic recession or when there is any disruption in the economic system due to pandemics or natural disasters. The study utilized a time series dataset from 1960 to 2018. The best model that fit the data set, following the selection model criteria, was ARIMA (5,2,0) model with the lowest Akaike’s Information Criteria(AIC) and Bayesian Information Criteria (BIC) and smallest volatility. The study results showed that, on average, Zambia’s gross domestic product will continue to rise over the next eight years. However, few recession (decline) points are expected in the period 2020 to 2022. It is hoped that the forecasts would be useful for researchers in Zambia, including the fiscal and monetary policy makers.

The VLIW has the fife stages of pipelines for executing the architecture are (1) fetching the 128-bit instruction memory, (2) decode stage or it is also called as the operands reading stage because the total number of operands are implemented in this stage, (3) execution stage, here the operations with the parallel executions units which has the four operations, (4) memory stage is used for loading or for storing the data from/to the memory and (5) write back stage in this stage the outputs of all the stage is collected and write back into the register file for storing the output values. The whole process of implementation is implemented in the FPGA of the family of Spartan-6 XC6SLX-3CSG324 device. In this proposed architecture the performance of the architecture is increased by reducing the time taken to execute the CPU of Xst completion of the architecture
Mobile Banking Adoption in Organization: Review of Empirical Literature
Authors: Mujahed Hamed M. H. , Ahmed Elsadig Musa , Samikon Siti Aida
Published: September 2020

This study reviews literature on mobile banking adoption in organizations to identify its influential factors and its operationalization in prior literature. We classify the factors that influence mobile banking adoption using the three contexts suggested by the Technology, Organization and Environment (TOE) framework, namely, technology, organization, and environment. The finding suggests that the influences of these factors vary across studies and most of the studies have operationalized mobile banking adoption using intention to adopt mobile banking or binary variable, rather than the actual use of the technology.
A Helium-flash-induced Mixing Event Can Explain the Lithium Abundances of Red Clump Stars
Authors: Schwab Josiah
Published: September 2020

Observations demonstrate that the surface abundance of

in low-mass stars changes dramatically between the tip of the red giant branch and the red clump. This naturally suggests an association with the helium core flash, which occurs between these two stages. Using stellar evolution models and a simple, ad hoc mixing prescription, we demonstrate that the

enhancement can be explained by a brief chemical mixing event that occurs at the time of the first, strongest He subflash. The amount of

already present above the H-burning shell just before the flash, once it mixes into the cooler envelope and undergoes an electron capture converting it to

, is sufficient to explain the observed abundance at the red clump. We suggest that the excitation of internal gravity waves by the vigorous turbulent convection during the flash may provide a physical mechanism that can induce such mixing.
Review of Late Cretaceous volcanogenic massive sulfide mineralization in the Eastern Pontides, NE Turkey
Authors: REVAN Mustafa Kemal
Published: September 2020

The production of Cu-Zn from volcanogenic massive sulfide (VMS) deposits in the eastern Pontides began in the early 1900s, with the exploitation of high-grade ores scattered across the district. The district still possesses economically important blind VMS and associated sulfide deposits. Careful descriptive documentation of the typical features of these VMS ores illustrated the geological characteristics that are important in identifying ore localities and can be used to define exploration targets. The eastern Pontide VMS deposits are examples of volcanic-hosted massive sulfide deposits that exhibit many of the characteristics typical of bimodal-felsic- type VMS mineralization. Nearly all known VMS deposits in the region are hosted by the Kızılkaya Formation, which is characterized by Late Cretaceous dacitic/rhyolitic volcanic rocks that are typically located at the top contact of the dacitic/rhyolitic pile or within the lower part of the overlying polymodal sequence containing various proportions of volcanic and sedimentary facies. Most VMS deposits are composed of a mound of high-grade massive sulfides formed above a zone of lower-grade stringer veins and disseminated mineralization. The dominant sulfide minerals in most deposits are pyrite, chalcopyrite, and sphalerite. Au also occurs in some deposits. The hydrothermal ore facies are diagnostic of subaqueous emplacement of the Pontide massive sulfide deposits that were deposited on the Cretaceous ocean floor. The immediate host lithologies associated with VMS mineralization have typically experienced intense and widespread alteration. The trace element geochemical signatures of the host rocks indicated that the Pontide VMS deposits likely formed in an extensional tectonic regime during subduction. Major lineaments and circular structures exerted fundamental controls on the locations of the VMS deposits in the eastern Pontide district. Age determinations indicated that almost all of the deposits in this region formed in a restricted time interval between ca. 91.1 and 82 Ma. The sulfur isotope compositions of the ore-forming fluids were consistent with those of fluids derived from modified seawater.

Cyanobacterial blooms often consist of mixtures of microcystin-producing and microcystin-free species, and both can cause unpredictable effects on aquatic organisms. In this work, the subchronic effects of the cyanobacterial crude extracts (CCEs) from microcystin-producing and microcystin-free cyanobacteria with different microcystin concentrations (1, 10, and 50 μgL−1)on Daphnia magna were investigated. The life-history trait responses of D. magna to CCEs were determined based on survival, reproduction, and somatic growth. In addition, the physiological response, represented by the feeding rate of D. magna on green algae (Scenedesmussp.), after exposure to both types of crude extracts was estimated. Our results showed that both microcystin-containing (MCCE) and microcystin-free (NCCE) crude extracts insignificantly reduced survival but strongly enhanced reproduction and somatic growth of organisms. However, degradation of eggs and neonates of the gravid females exposed to CCEs was observed. In addition, the feeding rate of D. magna exposed to MCCE increased significantly, whereas no change in the feeding rate was observed for NCCE-exposed D. magna. In general, new and interesting aspects of the toxicity of MCCE and NCCE were revealed by this study, which contributes to the understanding of the toxicity of Pseudanabaena sp. extract on D. magna under bioassays.
Insights into the Daily Life of Le Corbusier: the agendas in the Fondation Le Corbusier
Authors: Benton Tim
Published: September 2020

The resources available for research at the Fondation Le Corbusier are many and varied. Among these, the agendas (diaries) offer particularly intriguing insights into the public and private life of Le Corbusier. These diaries present a number of difficulties to the researcher: the notes are often difficult to read and even more difficult to interpret. The organisation of the diaries has to be understood. The pages of the diaries are undated. Establishing the approximate dates for each page presents a challenge that can only be overcome by reference to a wide range of other documentation. This paper offers suggestions for how to analyse and interpret this difficult material. With a number of worked examples, an indication is given of some of the insights that can be obtained from mining this data.
Prediction Models
Authors: Tyagi Amit Kumar
Published: September 2020

Having/living convenient life through smart devices, people are more interested or more dependent on to predict something for future (i.e., with respect to their health, business, etc.). For that, many prediction models by several researchers are being used in many applications. Due to a vast (rapid) change in lifestyle, people are more prone to a number of life-threatening diseases when it comes to their well-being. Many of these diseases start developing their symptoms in their early stages. But, still many of these diseases like cancer, kidney damages remain unidentified in their developing stages. The earlier a disease is predicted, the easier it becomes to cure it and even prevent it. Predictive modeling provides a huge step forward in medical science in preventing the risk among patients. Prediction modeling is the process of analyzing current conditions to predict future results.
A Pathway to Differential Modelling of Nipah Virus
Authors: Rajan S. Dheva
Published: September 2020

This chapter is devoted to the study of mathematical modelling part of infectious diseases, especially the nipah virus. In the past few decades, one cannot deny that enormous new unanticipated diseases have been the cause of serious concern among the human community and that so many viruses have begun emerging and re-emerging though people are trying all means to get rid of diseases. It can even be said that diseases of all sorts are ruling the world. Early prediction of diseases that spread in humans plays a vital role to protect living beings. Most of such diseases are highly infectious, get transmitted from human to human or through some other vectors. Several research and developments take place in the pharma industry notably after the Second World War. Hence, the predictions are not just for theoretical purposes as quite a number of pharma industries use mathematical models for their findings in new medicines and even to decide the quantity of medicine production. This chapter gives an overview of the different researches conducted in mathematical modelling of nipah virus.
Clinical Decision Support Systems
Authors: Prabha V. Diviya , R. Rathipriya
Published: September 2020

Clinical data is increasing day-by-day mainly in hospitals by an ageing of the human population. Patients discharged from hospitals are readmitted due to health issues. As the number of patients increases, there are a smaller number of hospitals and an increase in healthcare costs. This results in ineffective decision making that minimizes the healthcare. Machine learning techniques score better for solving this kind of problem. The proposed work, minimum entropy feature selection with logistic regression (MELR), is performing better for the readmission rates. Decision cannot be based on the clinical knowledge and personal data about the patient. It must be precise in choosing the future patient outcomes. This chapter produces promising results for clinical data.
Heart Disease Prediction Using Machine Learning
Authors: B. Shiva Shanta Mani , V. M. Manikandan
Published: September 2020

Heart disease is one of the most common and serious health issues in all the age groups. The food habits, mental stress, smoking, etc. are a few reasons for heart diseases. Diagnosing heart issues at an early stage is very much important to take proper treatment. The treatment of heart disease at the later stage is very expensive and risky. In this chapter, the authors discuss machine learning approaches to predict heart disease from a set of health parameters collected from a person. The heart disease dataset from the UCI machine learning repository is used for the study. This chapter discusses the heart disease prediction capability of four well-known machine learning approaches: naive Bayes classifier, KNN classifier, decision tree classifier, random forest classifier.

Liver diseases avert the normal activity of the liver. Discovering the presence of liver disorder at an early stage is a complex task for the doctors. Predictive analysis of liver disease using classification algorithms is an efficacious task that can help the doctors to diagnose the disease within a short duration of time. The main motive of this study is to analyze the parameters of various classification algorithms and compare their predictive accuracies so as to find the best classifier for determining the liver disease. This chapter focuses on the related works of various authors on liver disease such that algorithms were implemented using Weka tool that is a machine learning software written in Java. Also, orange tool is utilized to compare several classification algorithms in terms of accuracy. In this chapter, random forest, logistic regression, and support vector machine were estimated with an aim to identify the best classifier. Based on this study, random forest with the highest accuracy outperformed the other algorithms.
Human Capital Management in the Tourism Industry in Portugal
Authors: Figueira Luís Mota , Honrado Graciete Reis , Dionísio Marta Santos
Published: September 2020

Although there is a sustained and sustainable consumption and use of resources underlying it, tourist visitation always has a strong human component. Competitiveness in the tourism industry requires professionals with a set of skills integrated in the domain of “knowing how to do” and “knowing how to be.” Portugal has extraordinary tourism resources and potential on which a relevant activity with a growing weight in the country's economy is being developed. Therefore, there are many challenges in order to ensure a competitive and high-quality tourism offer, being the dynamizing and mobilizing core of the country's economic and social sectors. In 2017, Portugal registered a record number of 20.6 million tourists, according to CIP data. For this reality to have a sustained term growth, it depends on the possibility of companies “driven” by knowledge to access highly skilled human resources familiar with new technological developments. This chapter explores human capital management in the tourism industry in Portugal.
A Generations' Perspective on Employer Branding in Tourism
Authors: Binder Daniel , Miller James William
Published: September 2020

The tourism industry is facing tremendous challenges from labor shortages and a resulting loss of competitiveness. Changing digital environments as well as young people's communication habits and ideas regarding work-life balance are raising human resources related questions, to which currently no answers exist. In light of this issue, this chapter focusses on employer branding as a way to motivate present employees and attract new ones. It includes a discussion of different theories of workplace motivation, followed by a look at payment and further education issues. The so-called Generations Y and Z are investigated in the context of the labor shortage, and the generation concept itself is critically reflected. Furthermore, labor force aspects and working conditions in tourism are examined, with specific evidence from Austria. Finally, the discussion outlines an employer branding strategy as a way to address this problem.
Blue Economy and Tourism
Authors: Ramos Jorge , Drakeford Benjamin
Published: September 2020

The ocean covers about two-thirds of Earth's surface, and until sometime ago, it was considered an endless source of resources. The distorted advancement of technology was by far too steep in comparison to the pace of renewable resources recovery. Today, it is known that sustainability is fundamental in order to preserve sea resources and ensure their high resilience. Certain sectors are highly demanding in terms of human capital, and the tourism industry seems to be on the rise. Worldwide tourism keeps growing, and several phenomena have determined some trends, particularly related to recreational and cultural activities. Tourism inflicts a high pressure on coastal resources at different levels. Natural and social scientists strive to find solutions for the problem, whereas some other sectors of society try to reach solutions in terms of business opportunities. The tourism industry has a large stake in these issues because it is an important opportunity to take advantage of human capital and simultaneously educate people for more sustainable uses of sea resources.
