Stock Price Prediction using Machine Learning Algorithms
Authors: Pawaskar Shreya
Published: January 2022

Abstract: Machine learning has broad applications in the finance industry. Risk Analytics, Consumer Analytics, Fraud Detection, and Stock Market Predictions are some of the domains where machine learning methods can be implemented. Accurate prediction of stock market returns is extremely difficult due to volatility in the market. The main factor in predicting a stock market is a high level of accuracy and precision. With the introduction of artificial intelligence and high computational capacity, efficiency has increased. In the past few decades, the highly theoretical and speculative nature of the stock market has been examined by capturing and using repetitive patterns. Various machine learning algorithms like Multiple Linear Regression, Polynomial Regression, etc. are used here. The financial data contains factors like Date, Volume, Open, High, Low Close, and Adj Close prices. The models are evaluated using standard strategic indicators RMSE and R2 score. Lower values of these two indicators mean higher efficiency of the trained models. Various companies employ different types of analysis tools for forecasting and the primary aim is the accuracy to obtain the maximum profit. The successful prediction of the stock will be an invaluable asset for the stock market institutions and will provide real-life solutions to the problems of the investors.

COVID-19 has become a global pandemic, and one of the government's actions in the education sector to prevent transmission through online class activities or online classrooms has been adopted. During the pandemic, it was discovered that using computers with improper or non-ergonomic body postures during online classes might cause muscular fatigue and raise the incidence of musculoskeletal problems. Using the Rapid Entire Body Assessment (REBA) method, this study seeks to detect musculoskeletal complaints and assess the posture of UMM students when using a laptop. Because online learning lasts more than 2 hours, posture that is not in accordance with the comfort of using a laptop can lead a person to exhaust more rapidly in front of a laptop for a relatively long period, especially in the upper neck, back, and waist, which stand for 80% of the body parts. This is supported by the study of respondents using a questionnaire distribution technique that provided a REBA score of 7 and a moderate risk level, indicating that remedial action is required. After a recommended improvement with a low risk level for MSDs, a REBA score of 3 was established. Suggestions that can be considered are that it is necessary to improve sitting work posture, it is recommended to work on a table and sit in a reclining chair so that the proposed work posture improvement can be carried out.

De una “feliz revolución” a una “revolución criminal”. El concepto de revolución en la prensa de Lima y Buenos Aires en tiempos de legitimidad política (1810-1816)
Authors: Morán Ramos Luis Daniel , Carcelen Carlos
Published: January 2022

En tiempos de conmemoraciones de los bicentenarios de las independencias en América Latina y ante una importante renovación historiográfica, este trabajo reflexiona en torno a las características, los significados y los usos políticos del concepto de revolución en los discursos de la prensa de Lima y Buenos Aires en aquella compleja coyuntura de guerra (1810-1816). En ese sentido, el concepto de revolución sirvió para defender los intereses de los grupos de poder realista o revolucionario, caracterizar en ambos casos un proceso político, los agentes históricos que se enfrentaron en él, los contrastes, las variaciones y los significados del término en el interior de sus espacios de influencia y la propia legitimidad y práctica política.
Puestos fronterizos, guardias, fortines y fuertes de la frontera rioplatense tardocolonial: entre la polisemia y las carencias castrenses
Authors: Iraola Eduardo , Aguirre Arnaldo Andrés
Published: January 2022

En la denominada frontera sur de América del Sur convergieron las poblaciones indígenas y las hispanocriollas que practicaron una serie de estrategias defensivas. Un conjunto variable de edificaciones militares se fue extendiendo entre la Banda Oriental del Uruguay (actual República Oriental del Uruguay) y Buenos Aires (Argentina), que se encontraban en una misma jurisdicción administrativa. Si bien estas estructuras castrenses compartieron las propias denominaciones de la corporación, no obstante, los aspectos constructivos pusieron en evidencia notorias diferencias. Los puestos fronterizos, guardias, fortines y fuertes distribuidos en la jurisdicción supusieron diferencias de dotación, aunque con más sutileza preservaron una importante polifonía.La historiografía clásica tendió a estudiar estas guarniciones de modo literal otorgando a cada estructura militar las características que implicaban su nominación, mientras que artículos más recientes, que problematizan estas propuestas, contribuyen a interpelar la materialidad de esas tipologías militares al mostrar cómo en numerosas oportunidades no llegaban ni la dotación de soldados ni la de artillería, al tiempo que la edificación únicamente existía en los planos. El objetivo de este artículo es, por una parte, presentar una primera indagación de carácter comparativo en torno a las denominaciones constructivas militares a ambos lados del Río de la Plata. Por otra parte, apuntamos a contraponer el empleo de dichas denominaciones y la materialidad expresada en los fondos documentales.

Authors: Lapierre Michelle , Gloël Matthias
Published: January 2022

Este artículo pretende identificar cómo se desarrolló la convivencia entre las prácticas médicas indígenas y españolas en el Chile del primer siglo de conquista. En relación con la metodología de esta investigación, se han revisado todas las fuentes primarias disponibles que registran la experiencia de conquistadores y religiosos en el Chile de la época, y se buscó en ellas registros de intercambio, convivencia y diálogos interculturales en el ámbito médico. Los resultados muestran numerosos registros históricos de convivencia entre ambas culturas en el ámbito sanitario, cuyas formas y detalles se explicitan en este artículo. Concluimos que las diferencias que separaban a ambas culturas se manifestaban principalmente en otros aspectos, no así en lo médico, donde existió intercambio de saberes, valoración cultural, coincidencias, hibridez e incluso prácticas conjuntas.

Income inequality, regional characteristics and household’s conspicuous consumption: An empirical study in developing market
Authors: Lastuti Yeti , Khoirunurrofik Khoirunurrofik
Published: January 2022

This study aims to analyze the effect of income inequality and regional characteristics such as ethnicity and religion on conspicuous consumption for visible and invisible good types of households in the Indonesian regions by dividing regions into regions with low and high-income inequality levels based on the value median Gini index in Indonesia. The data set deployed in this study were pooled data collected from households provided by the Indonesian Central Bureau of Statistics 2017 and 2018. Employing the OLS method, we find that 1) income inequality has a negative effect on visible goods, and positive effect on invisible goods, 2) ethnicity and religion give an effect on visible and invisible goods. The government should pay attention to the phenomena of conspicuous consumption because numerous problems will likely arise if this conspicuous consumption is ignored. High conspicuous consumption would tend to lead to a materialistic lifestyle causing a higher inequality. In addition, the crime rate could equally increase given the high risk of conspicuous consumption in attracting others’ attention to individuals’ wealth.
Structure of the Potential Virulence Factor from Francisella tularensis Shows Unexpected Presence of the SHS2 Motif and Similarity to Other Bacterial Virulence Factors

Published: January 2022

Pathogenic bacteria attack their host by secreting virulence factors
that in various ways interrupt host defenses and damage their cells.
Functions of many virulence factors, even from well-studied pathogens,
are still unknown. Francisella tularensis is a class A pathogen and a
causative agent of tularemia, a disease that is lethal without proper
treatment. Here we report the three-dimensional structure and
preliminary analysis of the potential virulence factor identified by the
transcriptomic analysis of the F. tularensis disease models that is
encoded by the FTT_1539 gene. The structure of the FTT_1539 protein
contains two sets of three stranded antiparallel beta sheets, with a
helix placed between the first and the second beta strand in each sheet.
This structural motif, previously seen in virulence factors from other
pathogens, was named the SHS2 motif and identified to play a role in
protein-protein interactions and small molecule recognition. Sequence
and structure analysis identified FTT_1539 as a member of a large
family of secreted proteins from a broad range of pathogenic bacteria,
such as Helicobacter pylori and Mycobacterium tuberculosis. While the
specific function of the proteins from this class is still unknown,
their similarity to the H. pylori Tip-α protein that induces TNF-a and
other chemokines through NF-kB activation suggests the existence of a
common pathogen-host interference mechanism shared by multiple human
pathogens.
Aortic annulus elevation for aortic valve and root replacement
Authors: Jahanyar Jama , Mastrobuoni Stefano , Munoz Daniel E. , Aphram Gaby , Kerchove Laurent de , Elkhoury Gebrine
Published: January 2022

Aortic valve and root replacements require an in-depth understanding of
the aortic root and annulus. Both structures can be asymmetric at times,
and this needs to be recognized and taken into consideration when
peforming valve-sparing operations or other root-replacement procedures.
Moreover, the geometry of the aortic annulus can be altered, and when
performing an aortic root replacement this can distort the geometry of a
neo-aortic valve for instance, and lead to valve dysfunction, which is
difficult to reverse. We are describing an altered aortic annulus, which
required modification through annulus elevation before proceeding with
aortic root replacement with a graft-reinforced pulmonary-autograft.
Single-particle fluorescence tracking combined with TrackMate assay reveals highly heterogeneous and discontinuous lysosomal transport in freely orientated axons

Published: January 2022

Axonal transport plays a significant role in the establishment of
neuronal polarity, axon growth, and synapse formation during neuronal
development. The axon of a naturally growing neuron is a highly complex
and multifurcated structure with a large number of bends and branches.
Nowadays, the study of dynamic axonal transport in morphologically
complex neurons is greatly limited by the technological barrier. Here, a
sparse gene transfection strategy was developed to locate fluorescent
mCherry in the lysosome of primary neurons, thus enabling us to track
the lysosome-based axonal transport with a single-particle resolution.
Thereby, several axonal transport models were observed, including
forward or backward transport model, stop-and-go model, repeated
back-and-forth transport model, and cross-branch transport model. Then,
the accurate single-particle velocity quantification by TrackMate
revealed a highly heterogeneous and discontinuous transportation process
of lysosome-based axonal transport in freely orientated axons. And,
multiple physical factors, such as the axonal structure and the size of
particles, were disclosed to affect the velocity of particle
transporting in freely orientated axons. The combined single-particle
fluorescence tracking and TrackMate assay can be served as a facile tool
for evaluating axonal transport in neuronal development and axonal
transport-related diseases.

to cut down trees. As one of the possibilities, the method of "model" cutting
can be used, which is practically the only one that allows assessment value
without cutting trees. It consists in estimating the volumes of assortment
classes only on the basis of tree dimensions (d and h) and valid standards
for forest exploitation products, and later, by multiplication with prices,
the required value is obtained. As other characteristics of the tree (wood
defects) are not taken into account in this procedure, it is obviously an
ideal (maximum) value. In order to harmonize it with the real value, which is
always lower than the "model" value, a request is imposed for the correction
of the "model" value with appropriate coefficients. In this research, an
attempt was made to obtain such coefficients for material from thinning in
beech high (5,973 trees) and coppice (1,842 trees) forests and to check the
degree of accuracy during their application.
An innovative chainsaw blockage method using alcohol detection

Published: January 2022

The paper presents the working principle of the alcohol sensor, which is
connected to the on/off switch on the chainsaw. The alcohol sensor switches
off the chainsaw via the transmitter and receiver, if it detects that the
worker is under the influence of alcohol. The connection between the
transmitter and the receiver is remote, via radio waves. The alcohol sensor
contains a mesh that heats up due to 5V voltage impact and reacts to alcohol
vapors. This reaction is an incentive to send a signal from the transmitter
to the receiver. Blockage - switching off of the chainsaw occurs when a short
circuit is made between the power supply and ground. This short circuit also
occurs when the chainsaw stop switch is manually switched to the "0" state.
By using an alcohol sensor, a transmitter and a receiver, the "0" state on
the switch is achieved wirelessly. The receiver (relay) makes a short circuit
instead of a switch, which causes the chainsaw to stop working. This way of
stopping the chainsaw indirectly protects the worker from injuries due to
alcohol consumption.
"I could easily get professional help if I wanted to": Professional help-seeking intentions and the Theory of planned behaviour
Authors: Naumova Katerina
Published: January 2022

This study used path analysis to evaluate the ability of the Theory of planned behaviour to predict professional help-seeking intentions in an adult community sample (N = 470, 51% female, age range: 18?64 years). The results showed that perceived behavioural control was the most significant antecedent of help-seeking intentions, positive attitudes increased the likelihood to seek professional help, however, their effect was small, while subjective norms were not relevant. Past help-seeking had a small direct effect on intentions, yet equally strong as the total indirect effect via attitudes and perceived behavioural control. Psychological distress affected intentions only indirectly. Difficulties with self-disclosure were the only barrier that had a partially mediated effect on intentions through perceived behavioural control. The findings are discussed with respect to the utility of the TPB model, as well as in the wider context of professional help-seeking and interventions to encourage the utilization of mental health services.

Introduction. Idiopathic granulomatous mastitis (GM) is described as a very rare, non-lactating, chronic mastitis that occurs primarily in women of childbearing age. Significant clinical problem related to GM is the diagnostic differentiation from breast cancer. Less advanced forms of GM can be successfully treated with limited surgical excisions and radical treatment is recommended only for the most extensive forms. Case report. First examination of the patient, by the surgeon at Oncology Institute of Vojvodina was in December 2018, when initial suspicion of breast cancer was set up. Core needle biopsy was performed and after histopathological (HP) analysis, confirmation of GM was obtained. The patient was initially offered Prednisone and Methotrexate therapy, which she refused and accepted only surgical treatment. Surgical treatment was performed few weeks after needle biopsy and consisted of performing a nipple spearing mastectomy with excision of the orifices of all fistulous ducts and their primary sutures. The HP findings of the operative specimen confirmed the diagnosis of GM. While there were no signs of dieses relapse, patient was suggested secondary reconstruction of the left breast. Twelve months after the primary operation, secondary breast reconstruction was performed with the interposition of a contoured silicone implant into a muscle pocket in a standard manner. Conclusion. Nipple spearing mastectomy with secondary breast reconstruction is esthetically satisfactory treatment for patients with locally advanced GM.

Pancreatic β-cells adapt to compensate for increased metabolic demand during obesity. Although the miRNA pathway has an essential role in β-cell expansion, whether it is involved in adaptive proliferation is largely unknown. First, we report that EGR2 binding to the miR-455 promoter induced miR-455 upregulation in the pancreatic islets of obesity mouse models. Then, in vitro gain- or loss-of-function studies showed that miR-455 overexpression facilitated β-cell proliferation. Knockdown of miR-455 in ob/ob mice via pancreatic intraductal infusion prevented compensatory β-cell expansion. Mechanistically, our results revealed that increased miR-455 expression inhibits the expression of its target cytoplasmic polyadenylation element binding protein 1 (CPEB1), an mRNA binding protein that plays an important role in regulating insulin resistance and cell proliferation. Decreased CPEB1 expression inhibits elongation of the poly(A) tail and the subsequent translation of Cdkn1b mRNA, reducing the CDKN1B expression level and finally promoting β-cell proliferation. Taken together, our results show that the miR-455/CPEB1/CDKN1B pathway contributes to adaptive proliferation of β-cells to meet metabolic demand during obesity.
Faster R-CNN Structure for Computer Vision-based Road Pavement Distress Detection

Published: January 2022

Smart cities can be controlled in all aspects and it is desired to have a structure that is planned to have controllable feedback. Asphalt is generally used as pavement material on roads that provide transportation of vehicles such as cars and buses on the highway. Asphalt material is deformed due to weather conditions, heavy vehicle passage. In the smart city structure, similar deformations should be reported to the relevant unit. In this article, it was tried to determine the deteriorations on the asphalt by selecting the data set obtained from a region with image processing methods and deep learning technique. With the action camera placed in an automobile, a total of 4315 asphalt images with various distortions and without any deterioration were used as dataset. The dataset was classified using a pixel-based Faster Region-based Convolutional Neural Network. Accuracy, precision and sensitivity values were used to make the performance result obtained as a result of classification meaningful. With this proposed method, the average accuracy rate was 93.2%. With these results, an approach that can automatically detect asphalt deterioration in smart city structures has been developed.
Human Trafficking of People with a Disability: An Analysis of State and Federal Cases
Authors:   Washington University, St. Louis, USA, Nichols Andrea , Heil Erin ,   Southern Illinois University, Edwardsville, USA
Published: January 2022

The current academic discourse examining human trafficking is lacking in focus on survivors with a disability. The increased likelihood of abuse experienced by people with a disability is well documented in the research literature, and a small body of research indicates heightened sex trafficking victimization of minor girls with a disability. Yet, very little research specifically examines sex and/or labor trafficking of people with a disability, and no systematic research analyzes prosecuted cases of trafficking with disability as the focal point of analysis. Drawing from a content analysis of 18 federal and 17 state cases of human trafficking, the current study specifically aimed to increase our understandings of sex and labor trafficking involving survivors with a disability. The findings revealed the following patterns and themes: 1) the type of trafficking experienced (sex, labor, or both), 2) whether state level or federal cases 3) the types of disabilities identified among trafficking survivors, 4) the nature of the relationship between traffickers and survivors, 5) methods of recruitment, 6) case outcomes; and 7) demographic characteristics of traffickers and survivors (e.g., gender/citizenship). Implications include prevention efforts in the form of developmentally grounded sex education and healthy relationships curriculum for survivors with an intellectual disability, as well as specialized anti-trafficking training for those in legal, healthcare, and social services that is inclusive of people with a disability.
Sorority Women's Perceptions of Survivors' Services and Justice on an Urban Campus

While researchers have attempted to estimate the prevalence of and identify risk factors for sexual assault, less is understood about the relationship among populations at high risk for sexual assault and their perceptions of survivors’ services organizations and justice. The purpose of this investigation is to contribute to existing research through exploratory qualitative analyses of 43 undergraduate sorority women’s perceptions of survivors’ services and justice on a large, urban campus in the Pacific Northwest in the United States. Results of these exploratory analyses revealed that the sorority women had preferences for informal confidants and services whom they could trust concerning matters of sexual violence. The women also discussed that they would prefer confidential and mental health competent services for fear that disclosing sexual violence might draw public attention to them. On the same note, the women expressed a preference for justice that would prioritize their reputation and minimize stigmatization and highlighted how disclosure of sexual violence could impact their social, educational, and employment opportunities. Moreover, they described a fear of being blamed or not believed about sexual violence. Lastly, participants supported relatively punitive sanctions for perpetrators. Overall, participants cited many barriers to accessing formal support services, exposing the persistent justice gap that remains for this population. Findings suggest a need for outreach regarding campus services designed to address sexual violence.

The objectives of this research were to investigate whether there is positive influence after the implementation of TTW toward students’ descriptive writing achievement and to describe how is students’ response after they are taught by TTW. This research was a quantitative research. The sample of this research was the tenth graders of senior high school students. The writing test which consists of pre-test and post-test was used as the research instrument. The data were analyzed by using Paired Sample T-Test to answer the first question and descriptive statistics was used to answer the second question. The result showed that there was statistically an improvement of students’ descriptive writing achievement of which the result was significant to 0.000 < 0.05. Moreover, the students gave positive response toward the implementation of TTW. It was proved by the result of the analysis of the questionnaire of where the students mostly chose agree and strongly agree. This research suggests that teaching writing descriptive text by using TTW can give positive influence and positive response toward students’ descriptive writing achievement.
