Predicción de precios futuros de acciones representativas de la Bolsa Mexicana de Valores (Índice de Precios y Cotizaciones, IPC) mediante técnicas de inteligencia artificial
Authors:   , Martínez Escobar Juan Andrés , Mora Gutiérrez Román Anselmo
Published: August 2021

In this work, a new methodology is presented to analyze and predict the behavior of stocks of the Mexican Stock Market based on the synergistic concatenation of non-parametric statistical strategies and multi-objective optimization models. This methodology involves two phases. The first (filtering) leverages an automated process for the analysis, evaluation, and selection of the necessary and relevant information: for the characterization of the behavior of each action. The second (the model adjustment phase) involves adapting and solving a multi-objective model for the prediction of prices of the selected stocks. The database used in this work includes the behavior of twelve significant stocks in the Mexican stock exchange in the period 2006 to 2016, the source code used is available in “http://bit.ly/396h3J1”; the data was obtained from a specialized financial markets platform for Latin America. The numerical results show that the filtering phase can identify a compact set of relevant variables with a significant influence on the future price of each stock. In the second phase, the data from 2016 is used to predict the multi-objective model, that compared with the multiple linear regression model, provides a considerable improvement in the quality of the predicted observed data. The model generated from the second phase has reliability greater than 95%.
From a Caring State to an Investing State. Stages of a Changing Welfare Model in Labour Market Policy
Authors: Csoba Judit
Published: August 2021

In this paper, we investigate the changing model of social security. The analyses are focusing on changes in labour market policies which have taken place in the countries of the European Union. With the critical review of scientific literature of welfare changes, we try to answer the next questions. What circumstances led to the shift from the welfare state focusing on welfare benefits and services to the generally accepted model of the activating? What reforms and what stages lead to the transformation of the welfare model especially in the area of labour market policies? How the earlier integration efforts, which had mainly focused on entitlement, was replaced with a market-based approach like social investment?

The most important result of the critical analysis is the presentation of the policy model transfer between the states of the European Union and the steps of the reform process, which jeopardise the enforcement of the citizen's social rights.

The first part of the study presents the theoretical framework for the transformation of the labour market policies, the key pillars of the welfare state and the term “activation state” and “investing state”. The second part examines the key features of five stages of changing model.

Authors: Lee Hanna , Han Jeong-Won
Published: August 2021

Objective

This study aimed to investigate the physical activity of children with decreased visual acuity, thereby providing basic data for developing strategies to enhance the physical activity of school-age children.

Methods

The participants were 1,194 children and 1,194 parents who participated in the 10th Korean Children Panel Survey. Logistic regression analysis was conducted to examine the status of the physical activity of children with decreased visual acuity according to the accessibility of community facilities.

Results

The mother perceived the accessibility of community facilities as low, children with decreased visual acuity reported 1.20 times shorter over-the-weekend leisure activity time compared with vision-typical children, and they spent 1.41 and 1.33 times shorter on caring for pets and religious activity, respectively.

Conclusions

To increase the physical activity of children with decreased visual acuity, family-oriented interventions should be provided. It is also important to establish a community environment with enhanced accessibility of community facilities by examining the level of accessibility perceived by parents.

Authors: Liu Yu , Whittemore Robin , Guo Hong , Chen Yan , Zhang Wei , He Qiao
Published: August 2021

Objectives

To describe the quality of life (QOL) of adults ≥60 years of age in communities in Beijing and explore demographic, clinical, and psychological factors associated with QOL.

Methods

This was a cross-sectional study. A total of 363 older adults were recruited, in which 313 completed the questionnaires. Depressive symptoms were measured with the Self-Rating Depression Scale (SDS) and QOL was analyzed with the 36-item short form (SF-36). The t-test and Mann-Whitney U tests were used to compare QOL by gender and age group. Factors associated with QOL were determined using multiple linear regression.

Results

Among 313 older adults, depressive symptoms were observed to be prevalent to the extent of 16.6%. Overall, participants had higher QOL in the domains of social role functioning and emotional role functioning, with lower QOL in the domains of physical functioning and general health perceptions. There were no significant differences in QOL between women and men. However, there were significant differences between different age groups, with older adults having better mental QOL than younger adults. Better physical QOL was associated with less depressive symptoms, having a partner, and younger age (R
2 = 28.7%). Better mental QOL was associated with less depressive symptoms, less chronic disease, and older age (R
2 = 34.7%).

Conclusions

With aging, physical QOL was lower and mental QOL was better. Less depressive symptoms, having a spouse or partner, and young–old age assert positive influence on physical QOL of the older adults; and less depressive symptoms, no chronic disease, and older age assert positive influence on mental QOL.
The concentration-response functions for short-term exposure to ambient air pollution
Authors: Szyszkowicz Mieczysław
Published: August 2021

Introduction. There are a few statistical approaches to estimate health impacts of the ambient air pollution concentrations. Air health effects are often studied in short-term exposure. In this context two main techniques are used; time-series and case-crossover (CC). This work focuses on the CC methodology. In the standard method risk is estimated using log-linear models.
Aim. This work proposes other types of the models.
Material and methods. The CC design is applied with various transformations of air pollution concentration. The mortality data are used for the period from 1987 to 2015 for Toronto, Canada. Daily concentration level of ambient ozone is considered as an exposure. The ozone concentration is transformed and used in the statistical models. The transformation is a product of two parts; a simple function such as logarithm and a logistic function as a weight. The transformed concentration is used in the CC statistical models. The models estimate the coefficient related to transformed concentration. It allows to construct the concentration-response function. The generated models are assessed using the Akaike information criterion (AIC).
Results. The relative risks (RR), reported at 75th percentile of the concentration (55 ppb) are different. The standard CC model gives RR=1.0195 with the 95% confidence interval (1.0035, 1.0358), whereas the model with the transformation gives better fit and estimates RR=1.0054 (1.0026, 1.0082).
Conclusions. The proposed methodology allows to construct an accurate approximation of the concentration-response functions. These functions provide adequate approximations and also identify a potential threshold.

Authors: Buscot Gilles
Published: August 2021

Que ce soit pendant ou après la « Grande Guerre », la chanson fait partie des langages artistiques populaires que ce conflit majeur a suscités. De fait, la Première Guerre mondiale est aujourd’hui encore une source d’inspiration pour certains chanteurs français et allemands. L’article examine la manière dont le propos a changé depuis la guerre elle-même où les chants patriotiques rivalisaient avec quelques chansons pacifistes. Puis comment certaines chansons se sont « réactivées » durant d’autres périodes de conflits. Et enfin comment une volonté de témoignage, de dénonciation et de réconciliation s’est progressivement imposée à travers la chanson, mais avec des modalités différentes de part et d’autre du Rhin.

The need for horticulturist expertise in plant conservation: challenges and opportunities
Authors: Smith Paul
Published: August 2021

As many as 40% of the world’s plant species are currently threatened with extinction, and botanic gardens have an important role to play in restoring habitats and supporting plant species recovery in situ. Specialist horticultural skills are essential for proactive plant conservation and management. However, there are a number of impediments to deploying horticultural expertise where it is needed the most, including lack of information about which species and recovery programmes need expertise, where that expertise can be found, and institutional or practical impediments such as availability of time and funding. In this paper, the author presents details on tools and resources developed by Botanic Gardens Conservation International designed to engage and support the participation of horticulturists in plant conservation.
Candide and Botanical Software: technology cultivating garden visitation and collection management

Published: August 2021

Abstract

It is clear that the biodiversity crisis and overarching threat of climate change are having a fundamental impact on the biology of the planet. Botanic gardens, and related institutions, are uniquely positioned as centres of expertise in plant biodiversity. Their efforts in the exploration and documentation of biodiversity are also a fundamental prerequisite for the conservation of plants. The systematised and structured documentation of a garden’s collection of plant material, together with the collection policy and overall mission, characterises an institution as a botanic garden. However, the currently available tools and processes are not cost-effective, accessible at a global level, and do not provide the necessary efficiency for the needs and workflows of botanic gardens and plant collection management. In the context of gardens and visitation, there is also a growing disconnection between people and plants, particularly in an increasingly urbanised world.

Here, we present numerous innovative initiatives towards tackling these challenges, assisted by technology. We discuss the application of machine-learning in the automatic identification of plants (including composite tools such as Augmented Reality), and digital engagement through mobile-based complementations to visitors’ experiences. We also explore the documentation of quality data for botanical collections, and how advancements in collection management systems will play a major role in the efforts of the botanic garden community, and use of their richly-diverse plant collections in the vanguard of research, conservation, education, and visitation. Thus, ongoing technological developments in tools for botanic gardens and their visitors, present positive and influential contributions in tackling global challenges associated with plant conservation and engaging the broadest and most diverse audiences.

Authors: Hughes Kate
Published: August 2021

The Sibbaldia & PlantNetwork Conference 2020 opened with a free session. Participants were required to register in advance and registration was open to anyone with access to the internet. 300 participants registered and 142 attended on the day. A recording of the session was available to view for six months after the event.

The format of the session was a chaired panel discussion which explored what excellence means in horticulture. Topics were shaped by participants’ entries into an online poll which collated responses to the question ‘What does excellence in horticulture mean to you?’ and a word cloud was created from these entries. The chair navigated a discussion through the ideas which were of greatest significance to participants, according to the responses given in the poll. Panellists presented their own experiences on the subjects discussed and shared how their organisations approach them. The result was a lively and informative discussion between five experts in the fields of horticulture and education which ranged particularly around the knowledge educators want to share, how standards are defined, and what institutions can do to foster excellence. The discussion moved on to how more young people can be drawn into horticulture and subsequent professional development opportunities.

Published: August 2021

This study describes the item details of the final semester questions in Arabic MAN 1 Pangkalpinang using the item response theory approach. The problem behind this research is that the development of Arabic final assessment items did not go through the correct stages. Therefore, this research is quantitative research. The subjects of this study were 176 students of class XI MAN 1 Pangkalpinang. The answer data is in the form of answers to questions in the final semester in Arabic which are 40 multiple-choice items with five answers. The results showed that the final results of the Arabic semester (1) proved valid, indicated by 40 items (100%) with loading factors; (2) proven to be reliable, indicated by the reliability coefficient of 0.884; (3) there are 33 items (82.5%) of the 40 items that have a good level of difficulty and distinguishing power so that they can be stored in the question bank and used in subsequent activities, while 7 items (17.5%) are item number 10, 26, 27, 29, 32, 34, and 35 do not meet the criteria for a good level of difficulty so they need to be revised or eliminated; and (4) suitable for use in students with low to moderate ability (θ) in the range -3.5 to +1.5 in logit. Future research is expected to be able to analyze Arabic language question items in the form of descriptive tests on a large scale or develop high-quality high-order thinking skills in Arabic.

Published: August 2021

The Covid-19 pandemic to date has caused learning to be carried out remotely to prevent further transmission of the virus. The use of Google Classroom is a solution for learning fiqh lughah online at this critical time. So far, there are still few studies that examine student perceptions of online learning of fiqh lughah. Therefore, this study aims to investigate student perceptions of online learning of fiqh lughah using Google Classroom. This research is exploratory, investigative research with 33 students as the subject. All exploratory data were analyzed using descriptive statistical techniques by adopting several steps: tabulating the Microsoft Excel application data, adding a percentage score to the data, and presenting the analyzed data in a summary table. These findings reveal that distance learning using Google Classroom gets a positive response from students even though they have to adapt more intensely to be comfortable with the learning process. Therefore, learning fiqh lughah through Google Classroom should be considered as an alternative media for online learning.

Perubahan iklim dan penggunaan lahan memiliki dampak yang besar terhadap keseimbangan air. Perubahan penggunaan lahan merupakan penyebab utama tingginya run off dibandingkan dengan faktor lainnya. Bencana alam yang terjadi di wilayah DAS (Daerah Aliran Sungai) merupakan indikasi bahwa fungsi hidrologi di wilayah DAS dalam keadaan terganggu dan tidak dapat mendukung sistem tata air yang optimal. Hampir setiap tahun terjadi banjir di kawasan DAS Kuranji yang menimbulkan kerugian secara materil dan korban jiwa. Salah satu bentuk upaya untuk menjaga kelestarian DAS adalah dengan melakukan konservasi pada wilayah – wilayah yang memberikan dampak buruk terhadap DAS seperti lahan kritis. Tujuan penelitian ini adalah mensimulasikan konservasi lahan kritis DAS Kuranji terhadap perubahan hasil air. Simulasi dilakukan terhadap 3 skenario penggunaan lahan yaitu konservasi 50 %, 80 % dan 100 % terhadap luas lahan kritis. Hasil penelitian menunjukkan bahwa terdapat 818,92 ha lahan kritis yang bisa digunakan untuk lahan konservasi. Simulasi perubahan penggunaan lahan terhadap lahan kritis dari beberapa skenario menunjukkan bahwa skenario konservasi 100 % menunjukkan kondisi hidrologi yang lebih baik. Artinya, semakin luas lahan yang di konservasi menjadi hutan campuran maka akan menurunkan hasil air, sehingga menurunkan aliran permukaan dan menaikkan volume air tanah DAS

Authors: Hidayat M. Reza
Published: August 2021

Dielectric materials play an important role in antennas in an effort to support data communication. The material used by the dielectric is usually not even one material, however, it is a combination of several dielectric materials. From the final simulation results, the antenna is obtained at a working frequency of 7.822 GHz with a return loss of -20.336 dB, a bandwidth of 830.6 MHz and a VSWR of 1.21. Whereas in the measurement results of the horn antenna using dielectric material that has been realized, it is found that the antenna is able to work at a frequency of 8.41GHz with a return loss of -13.31 dB, a bandwidth of 110 MHz, and a VSWR of 1.61. The difference in parameter results could be due to dimensional differences between the simulated antenna and the antenna that has been realized. The difference in parameter results could be due to dimensional differences between the simulated antenna and the antenna that has been realized. Measurements are not carried out in a closed room or specifically for measuring the antenna, thus allowing interference to the waves from the antenna being measured because the simulation results are made in ideal conditions.

This work consists of the characteristics of production, assessment of the qualitative and quantitative composition of water, consideration of the process of water purification in the chemical shop, comparison and selection of coagulants and flocculants, and demonstration of the most affordable technology used at the CHPP which increases the efficiency of source water purification. The problem of pretreatment of the source water has always been relevant. The quality of the water used depends on the operation of boilers and turbines at the CHPP. The paper presents the average annual indicators of the quality of the source water, pre-treatment methods, and considers which reagents that do not require the cost of reconstruction of clarifiers can improve their performance. The initial water after the application of the test samples of coagulants and flocculants was studied. Conclusions are drawn about the work of clarifiers after the use of the proposed reagents.

n the western Antarctic Peninsula one of the areas the highest warming in the southern hemisphere has been identified. To characterize this tendency, we selected the Lange Glacier (LG) on King George Island, to evaluate: 1) LG surface temperature and dynamics using stakes with temperature data loggers; 2) LG submerged thickness and sea parameters through bathymetry (BT) and 29 CTD stations in front of LG; 3) glacier front (GF) using BT and a Digital Elevation Model (DEM); 4) change in GF position using DEM and historical data of GF width; 5) Calving flux (QC). Our findings showed 85 % of temperatures were above the 0 °C melting point (mean = 5.0 ± 5.2 °C). The stakes had an average ice loss of 9.3 ± 1.3 cm. The LG mean dynamics was 8.8 ± 1.5 m (0.40 ± 0.70 m/day), corroborated by Sentinel-1 satellite images (Offset Tracking = 0.43 ± 0.01 m/day). An intrusion of external waters warmer in the LG bay was identified, which destabilizes the water column due to convection processes. Our findings together indicated a continuous glacial melt that increases its dynamics due to the increase in temperature, with a contribution of fresh water to the Admiralty Bay. Based on historical results and this study, the LG retracement was estimated in 2,492 m between 1956 and 2019.

Although Chronic Subdural Hematoma (CSDH) is frequent in elderly patients, the CSDH can exceptionally cause a parkinsonism or aggravation of pre-existing parkinsonism. Only 27 cases reversible parkinsonism due to chronic subdural hematoma was reported in the literature. Disappearance of the extra pyramidal symptoms followed craniotomy and removal of the CSDH suggest a cause-and-effect relation between the haematoma and the clinical symptomatology. A case of a 62-year-old man with a two weeks history of parkinsonism caused by a CSDH reversible after surgery evacuation of the haematoma is reported. CSDH is a rare cause of reversible parkinsonism after surgery. CT scan must be recognized in any acute Parkinsonism or any deterioration of preexisting Parkinson disease to diagnose the Parkinsonism secondary to CSDH.

Tumour Induced Osteomalacia (TIO) caused by a Fibroblast-Growth- Factor-23 (FGF-23) secreting tumour is a rare paraneoplastic disorder. Patients often present with non-specific complaints of pain and stiffness however findings of hypophosphataemia and inappropriately suppressed 1,25 dihidroxyvitamin D are almost pathognemonic of this condition. We present a previously healthy 51-year-old man who presented with an 18 month history of body aches, hypophosphataemia, and an incidental finding of atraumatic foot fractures on x-ray. Technetium bone scan identified diffuse skeletal pathologic fractures. He was further found to have persistent hypophosphataemia, suppressed 1-25-dihidroxyvitamin-D, renal phosphate wasting with reduced Tubular Reabsorption of Phosphate (TRP), and an FGF-23 level more than twice the upper limit of normal. Fluorodeoxyglucose (FDG) Positron Emission Tomography (PET), Gallium-68 Dotatate PET and magnetic resonance imaging further identified and characterised a 40 mm FDG and Dotatate-avid lesion in the right third rib. Histopathological examination of a biopsy specimen revealed phosphaturic mesenchymal tumour with positive FGF-23 immunohistochemical staining arising in a background consistent with osteomalacia. After tumour resection, the patient’s hypophosphataemia, reduced TRP and elevated FGF- 23 normalised and he made an excellent recovery with rehabilitation. This case report illustrates the importance of a diagnosis of hypophosphataemia in a patient with musculo-skeletal aches and alerts clinicians of the differential diagnosis of TIO.
Effects of Glucan Supplementation on Aged Hematopoietic Progenitor Cells

Age related changes in activity of hematopoietic progenitor cells led us to investigate the possibility that glucan supplementation might overcome this suppression. In our study, we focused on differences of these cells in young (8 weeks old) and old (18 months old) mice after supplementation of yeast-derived insoluble glucan. Our results showed significant differences in reconstitution ability of progenitor cells as well as changes in level of stromal cell-derived factor 1α between young and old mice exist and can be partly restored by glucan supplementation.
A Case Report: Acute Respiratory Distress in a Patient with Anemia

Acute respiratory distress can be life threatening if proper management is delayed. The cause of respiratory distress needs to be diagnosed quickly in order to administer appropriate and timely treatment. However, it is sometimes difficult to tease out various conditions that can present as acute respiratory distress. We present such a unique case of acute respiratory distress in a patient with anemia. We show how the ability to differentiate between cardiogenic and non-cardiogenic pulmonary edema can help in diagnosis and appropriate timely management of acute respiratory distress.
La concepción de alma bella en el pensamiento de Jakob Fries y su diferencia con la concepción de alma bella en la filosofía de Hegel
Authors: Alfáro Carlos Victor
Published: August 2021

Robert Norton considera que la concepción de alma bella de Jakob Fries es similar a la esbozada por Georg Wilhelm Friedrich Hegel a través de su obra. Sin embargo, el autor de la Filosofía del derecho no incluye explícitamente a Fries dentro del elenco de representantes del pensamiento del alma bella. Sostengo que su ausencia solo puede explicarse porque el autor de Julius und Evagoras no poseía una noción de alma bella similar a la de Hegel.

Palabras clave

 Autoconciencia, conciencia, deber, virtud, belleza, Jakob Fries, Georg Wilhelm Friedrich Hegel.
