Published: January 2021

Antecedentes. El Índice de Bienestar (WHO-5) es un instrumento para medir bienestar general o síntomas depresivos en diferentes contextos y poblaciones. No obstante, el desempeño psicométrico de los instrumentos necesita revisión periódica. Objetivo. Revisar algunos indicadores del desempeño psicométrico del WHO-5, dimensionalidad y consistencia interna, en adolescentes escolarizados de Santa Marta, Colombia. Se diseñó un estudio metodológico en el que participaron 1.462 estudiantes de décimo y undécimo grado de colegios oficiales y privados, quienes diligenciaron el WHO-5. Se incluyeron estudiantes entre 13 y 17 años (M=16,0; DE=0,8), 60,3% de sexo femenino, y 55,3% de décimo grado. Se calculó la consistencia interna mediante los coeficientes de alfa de Cronbach y omega de McDonald y se llevó a cabo un análisis factorial confirmatorio (AFC) para corroborar la dimensionalidad. La consistencia interna mostró valores alfa de y omega de McDonald de 0,82. En el AFC se corroboró la estructura unidimensional del WHO-5 al observarse indicadores de bondad de ajuste dentro de los parámetros esperados (chi cuadrado=34,41; gl=5; p=0,001; RMSEA=0,063 (IC90% 0,044-0,084); CFI=0,988; TLI=0,975 y SRMR=0,018). El WHO-5 muestra alta consistencia interna y estructura unidimensional para la exploración de bienestar general en adolescentes escolarizados. Se necesita corroborar estos hallazgos en poblaciones con otras características demográficas.

Published: January 2021

En el presente documento se divulga parte de los resultados de investigación obtenidos en la elaboración de la Tesis para optar por el título de Doctora: Experiencias educativas que acogen la alteridad y las diferencias. El caso del Liceo VAL. En este proceso surgió interés y cuestionamiento por el marco legal y normativo, para promover la educación inclusiva en las instituciones educativas, adoptado en Colombia. Esto determinó la necesidad de un conocimiento profundo en el tema el cual, a su vez, remitió a un obligatorio contraste entre los pronunciamientos que emergen de este marco y la realidad del día a día en las escuelas, realidad evidenciada en investigaciones consultadas que se han desarrollado en el país. El propósito de este escrito es presentar un recorrido por los resultados del ejercicio de revisión documental, realizado desde una mirada crítica, el cual permitió develar la brecha que existe entre el objetivo de la educación inclusiva, plasmado en leyes y normas, y las experiencias pedagógicas que se suscitan en la escuela. Y, también permitió comprender, a manera de conclusiones, desde la mirada de las diferencias y la alteridad, que el marco jurídico de la educación inclusiva no tiene alcance para conmover la educación y a sus integrantes, así, se debe buscar un camino alternativo, basado en una mirada ética sobre la alteridad, que remita al cuestionamiento de elementos esenciales sobre cómo estar juntos en la escuela.

Imagining Sustainability Beyond COVID-19 in India
Authors: Thomas Bejoy , Bhar Soumyajit , Chakravarty Shoibal
Published: January 2021

The COVID-19 lockdown in India saw a spate of news stories suggesting improvements in environmental conditions. In this article, we caution against optimistic narratives of environmental revival. First, we analyse air pollution data before and during the lockdown to show that these improvements were temporary and a by-product of the severe restrictions placed on the normal functioning of the economy. Second, drawing upon data on income and inequality, we suggest that the human suffering witnessed during the lockdown was a result of widening social disparities since the 1990s. We argue that environmental priorities cannot be separated from social concerns, and equity has to be at the centre of imagining sustainability beyond the pandemic.

Authors: Dzemydienė Dalė , Maskeliūnas Saulius , Radzevičius Vytautas
Published: January 2021

The realization of really working, on-line system for evaluation of pollution of water processes requires to represent the complexity of such phenomenon. The multi-layered structure of distributed information systems under different responsibilities identify some problems for developing of an adequate decision support system (DSS) working on-line. The aim of this research is to develop the interoperable infrastructure of multi-dimensional data warehouses working on-line for integration of monitoring data, enabling the conditions for more adequate decisions. The design approach includes the constructions of the knowledge base with some layers of representation, including the domain specific ontology, which are needful for evaluation of impacts of water pollution. The results are integrated with the structures of the ISMA database, EuroWaterNet, Water Resource Management Information System – WRMIS, following the requirements of EU Water Framework Directive (2004). The presented results on integration of information sources and collaboration workflows help in searching of suitable indicators for revealing the situations of water pollution from wastewater bodies and can help to retrieve the main objects which influence the monitoring of effluxes in the Baltic Sea.
An alternate gradient method for optimization problems with orthogonality constraints
Authors: Sun Yanmei , Huang Yakui
Published: January 2021

In this paper, we propose a new alternate gradient (AG) method to solve a class of optimization problems with orthogonal constraints. In particular, our AG method alternately takes several gradient reflection steps followed by one gradient projection step. It is proved that any accumulation point of the iterations generated by the AG method satisfies the first-order optimal condition. Numerical experiments show that our method is efficient.

A Systematic Review of the Efficacy and Safety of Over-the-Counter Medications Used in Older People for the Treatment of Primary insomnia
Authors: Almond Sandrah-Ann M. , Warren Madelyne J. , Shealy Kayce M. , Threatt Tiffaney B. , Ward Eileen D.
Published: January 2021

OBJECTIVE: The purpose of this systematic review is to evaluate the available evidence for safety and efficacy of over-the-counter (OTC) sleep aids used for the treatment of insomnia in older people.
 DATA SOURCES: PubMed, EBSCO, and International Pharmaceutical
Abstracts.
 STUDY SELECTION: Five studies were included that involved humans 65 years of age and older being evaluated on OTC sleep aids in the outpatient setting.
 DATA EXTRACTION: Data extraction from each study included primary and secondary efficacy endpoints,
such as differences in the mean total sleep time, sleep latency, sleep efficiency, and number of awakenings, along with safety endpoints, such as psychomotor ability, cognitive ability, and adverse effect profiles. Both subjective and objective measures of changes in sleep and adverse effects
were included.
 DATA SYNTHESIS: Diphenhydramine had a statistically significant increase in sedation and decrease in number of awakenings but was not shown to be any less or more safe than compared products. Despite lacking safety issues, valerian was found to have no effect
on subjective or objective sleep outcomes. Overall, melatonin had the most evidence and was found to have a statistically significant positive impact on sleep measures without safety issues.
 CONCLUSION: Diphenhydramine and melatonin appear to be efficacious in improving some
sleep measures while causing minimal adverse effects. However, there are very few studies that examine the use of over-the-counter sleep aids in those 65 years of age and older with primary insomnia. Additional studies are needed in this population.
VALUE-AT-RISK BASED APPROACH FOR CURRENCY HEDGING
Authors: Khurana Rachna , Khetan Umang
Published: January 2021

Corporate FX risk management has gained complexity with an increased number of currencies involved and varying correlations among them. Existing literature has highlighted the need to account for cross-currency correlations when optimizing hedge ratios for portfolio management (Dowd, 1999). In this paper, we propose a Value-at-Risk (VaR) based model to estimate the optimal hedge ratio for a multi-national corporate that aims to minimize the cost of hedging at a given tolerance level of expected loss arising out of FX movement. The paper illustrates both parametric and historical methods of VaR estimation at a portfolio level as the first step in risk management. As a second step, an efficient-frontier is derived based on the expected VaR level at various hedge ratios and compared with associated hedge cost. The benefits of this approach include: identification of net exposures after correlations among currencies are accounted for in order to avoid duplication of hedges, and condensation of the parameters governing hedging decision into a single, intuitively-appealing number. The paper also highlights the need to frequently update the model’s assumptions as currency correlations and corporate exposures remain dynamic.

Published: January 2021

Background:

To optimize traumatic spinal cord injury (tSCI) care, administrative and clinical linked data are required to describe the patient’s journey.

Objectives:

To describe the methods and progress to deterministically link SCI data from multiple databases across the SCI continuum in British Columbia (BC) and Ontario (ON) to answer epidemiological and health service research questions.

Methods:

Patients with tSCI will be identified from the administrative Hospital Discharge Abstract Database using International Classification of Diseases (ICD) codes from Population Data BC and ICES data repositories in BC and ON, respectively. Admissions for tSCI will range between 1995–2017 for BC and 2009-2017 for ON. Linkage will occur with multiple administrative data holdings from Population Data BC and ICES to create the “Admin SCI Cohorts.” Clinical data from the Rick Hansen SCI Registry (and VerteBase in BC) will be transferred to Population Data BC and ICES. Linkage of the clinical data with the incident cases and administrative data at Population Data BC and ICES will create subsets of patients referred to as the “Clinical SCI Cohorts” for BC and ON. Deidentified patient-level linked data sets will be uploaded to a secure research environment for analysis. Data validation will include several steps, and data analysis plans will be created for each research question.

Discussion:

The creation of provincially linked tSCI data sets is unique; both clinical and administrative data are included to inform the optimization of care across the SCI continuum. Methods and lessons learned will inform future data-linking projects and care initiatives.
Simulation model of supply networks development
Authors: Fiala Petr , Kuncová Martina
Published: January 2021

The paper is dedicated to network development in the network economy. The current economy needs to look not only at networks with only dynamic flows and with a fixed structure, but as a dynamic system its structure evolves and changes. Structure and behaviour dynamics of network systems can be modelled as complex adaptive systems and use agent-oriented simulation to demonstrate origin, perturbation effects, and sensitivity with regard to initial conditions. Survival of firms is associated with the value of so-called fitness function. Firms whose fitness value falls below a certain threshold will be extinguished. In this way, it is possible to partially model network growth. A simulation model in SIMUL8 is proposed.
Optimal hybrid drive system architecture exploration considering performance index of 48V mild HEV
Authors: Ji Yonghyeok , Park Taeho , Lee Hyeongcheol
Published: January 2021

The 48V hybrid system has mostly adopted parallel hybrid system architecture. In the parallel hybrid system, various architecture can be derived depending on the location of the motor. In this paper, we explored a hybrid system architecture considering one or two motors and 48V electric supercharger and derived the optimal architecture by comparing the performance of each architecture. Performance of the hybrid system is mostly evaluated as fuel economy. However, since the hybrid system has increasingly been applied to various types of vehicles with different purpose of the operation, another performance index for evaluating a hybrid system is needed. Therefore, in this paper, we introduced an additional performance index to evaluate the hybrid electric drive system and used it to derive the optimal architecture of the hybrid electric drive system. We used Dynamic programming (DP) to evaluate each architecture and DP simulation was performed in the Matlab environment.
Study on fuel economy and generating energy of 48V MHEV with two motors
Authors: Ha Seongmin , Lee Hyeongcheol
Published: January 2021

In this paper, 48V MHEV vehicle with P0 + P4 structure is studied. In the previous paper, the best fuel economy was obtained when the energy obtained by regenerative braking was used only for EV driving. In an actual driving environment, a power generating function by an engine is essential. Therefore, not only regenerative braking energy but also additional energy from power generation is used for EV travel. Finally, the fuel economy is evaluated according to the amount of generating energy and control tendency of generating.

In this paper we discuss the Internet of Things (IoT) and industrial systems automation approach application for development a prototype of an autonomous beekeeping system. In this research we focus on one of the Arrowhead Framework core systems named the Event Handler system. MQTT service broker being a part of autonomous beekeeping system demonstrates the services provided by the Event Handler System. The proposed services broker applies a visual data flow programming approach. A Node-RED is used to prove viability and advantages of offered architecture implemented in a local automation cloud of autonomous beekeeping System of Systems. The autonomous beekeeping system’ prototype provides useful data on beehives and bee apiary status (internal and ambient temperature, humidity, weight of the hives, etc.) to the system users, so they can evaluate the hive status and take further action.
Simulation-based evaluation of automated trading strategies: a manifesto for modern methods
Authors: Cliff Dave
Published: January 2021

In many investment banks and major fund-management companies, automated "robot" trading systems now do work that 20 years ago would have required large numbers of human traders to perform: the rise of robot traders is a major success-story for artificial intelligence (AI) research. Although the technical details of currently profitable automated trading systems are closely guarded commercial secrets, the rise of robot trading can be traced back to a sequence of key AI research papers. Each of these key papers relied on minimal abstract simulation models of real financial markets: the simulators provide test-beds for trials in which the performance of different trading strategies could be evaluated and compared. Recent studies have revisited these seminal results, using more realistic simulations of contemporary financial markets, and have cast major doubts on core conclusions drawn in the original publications. Therefore, it seems reasonable to argue that present-day simulation methods are exposing significant problems in past research on automated trading. This position paper presents no new empirical results but instead presents a review of key past papers and an argument, a manifesto, for establishing a shared market-simulator test-bed that adequately reflects current real-world financial markets, for use in future evaluation and comparison of trading strategies.
Nonparametric frequency polygon estimation for modeling input data
Authors: Hague Stephen , AbouRizk Simaan
Published: January 2021

To construct valid probability distributions solely from input data, this paper compares three nonparametric density estimators: (1) histograms, (2) Kernel Density Estimation, and (3) Frequency Polygon Estimation. A pseudocode is implemented, a practical example is illustrated, and the Simphony.NET simulation environment is used to fit the nonparametric frequency polygon to a set of data to recreate it as a posterior distribution via the Metropolis-Hastings algorithm.

Published: January 2021

The industrial plants, in process industries, are often characterized critical environments and dangerous conditions respect the utilization of human workforce. These aspects are quite common in chemical, oil & gas, iron & steel plants where this combination of factors causes serious accidents. The aim of this study is to develop a new generation of intelligent autonomous system capable to support operations in these environments reducing the presence of workers in most risky operations. In order to succeed in this task, these new systems must be suitable to operate in complex industrial environments and to face related threats and risks. Indeed, this paper proposes an analysis of a complex industrial environment related to hot metal production by identify the most dangerous areas and operations as well as potential critical elements for autonomous vehicle use. Consequently, simulation solutions are proposed to support engineering of these innovative robotic system as well as development of new operations and procedures.
Investor Sentiment and Volatility Prediction of Currencies and Commodities During the COVID-19 Pandemic
Authors: Hoang Thi Hong Van , Syed Qasim Raza
Published: January 2021

In this note, we examine whether the volatility predictive power of investor sentiment for currencies and commodities is sensitive to the COVID-19 pandemic. The Credit Suisse Fear Barometer (CSFB) and the VIX are used to measure investor sentiment. The volatility of seven major currencies, gold, and oil is investigated. Using daily data from 2005 to 2020, we show that VIX is a better predictor than CSFB. However, they have no predictive power during the COVID-19 pandemic period. This may be attributed to the different nature of fear sentiment during the crisis.
An Analysis of the Dynamic Asymmetric Impact of the COVID-19 Pandemic on the RMB Exchange Rate
Authors: Fang Xing , Zhang Yu
Published: January 2021

In this paper, we assume that the COVID-19 pandemic exerts a time-varying asymmetric impact on the RMB exchange rate. Based on the Taylor rule model, we examine the RMB exchange rate fluctuations around the outbreak of COVID-19. We find that the RMB rate rose steadily before the outbreak but fluctuated during the pandemic. This shows that the pandemic had a transient time-varying impact on the RMB exchange rate.

Social media is becoming a critical part of everyone’s life. Social media has numerous platforms including Facebook, Twitter, Instagram, and LinkedIn. Impersonation is a common phenomenon found nearly on all social media platforms; it is the act of attempting to deceive someone by pretending that he is another person. Impersonators always try to hide a real account by making another similar profile to spread the fake contents on social media platforms making it very difficult to know the real accounts from the fake ones. Aims: This paper aims to write a comprehensive review on the social media impersonation, impersonation types, how to identify the social media impersonation, cases of social media impersonation, how to prevent impersonation, and how to protect the security of a social media user. Besides, the article explains the position of Islam toward impersonations including social media impersonation. Method: This is a narrative review of the existed literature review on the social media impersonation in the virtual world. Conclusion: Social media impersonation is the act of pretending that a person is another person which usually occurs on all social media platforms.
