Authors: Newbegin Luke , Chapman Brian E.
Published: January 2024

Personal electronic health records (PEHRs) enable patients access to their own medical records. Differences in access and use of PEHRs may create health disparities. We conducted a narrative literature review regarding the effects of race, language preference, education, income, and homelessness on PEHR usage as well as PEHRs content, particularly stigmatizing language. Of 3177 citations found, 75 articles were relevant. Patient race, language, income, and education predicted PEHR use, which could potentially exacerbate health disparities.

Published: January 2024

This research aimed to develop a model for real-time prediction of aerobic exercise exertion levels. ECG signals were registered during 16-minute cycling exercises. Perceived ratings of exertion (RPE) were collected each minute from the study participants. Based on the reported RPE, each consecutive minute of the exercise was assigned to the “high exertion” or “low exertion” class. The characteristics of heart rate variability (HRV) in time and frequency domains were used as predictive features. The top ten ranked predictive features were selected using the minimum redundancy maximum relevance (mRMR) algorithm. The support vector machine demonstrated the highest accuracy with an F1 score of 82%.

In the Optical Effects, the One-Way Synchronization Foresees Transformations Conserving Simultaneity and Spacetime Continuity, Replacing the Two-Way Einstein Synchronization and the Lorentz Transformations, Which Predict Instead a Spacetime Continuity Breach and a Weak Form of the Relativity Principle
Authors: Spavieri Gianfranco , Haug Prof. Espen Gaarder
Published: January 2024

We revise the optical effects of the Sagnac type where the moving closed contour is covered by a photon in the observable invariant time interval \(T\) . In lieu of the two-way Einstein synchronization, an internal one-way synchronization procedure along the contour can be adopted.

For the reciprocal linear Sagnac effect, where the emitter-receiver C* is stationary and the contour is in motion, \(T\) is no longer invariant for the Lorentz transforms, reflecting a weak form of the relativity principle. Instead, the relativity principle is preserved and \(T\) is invariant for transforms based on conservation of simultaneity.

In the standard linear Sagnac effect, if the local one-way speed along the optical fiber is assumed to be \(c\), the photon cannot cover the whole closed contour in the interval \(T\). The missing section represents a breach in spacetime continuity related to the "time gap" due to relative simultaneity. Our revision confirms the well-known result that the Lorentz transforms have limited validity and fail in interpreting these effects. The more general validity of transforms based on conservation of simultaneity, disproves Mansouri and Sexl's contended equivalence between relative and absolute simultaneity.

The reciprocal linear effect can be used for testing Lorentz and light speed invariance with observable variations of the first order in \(v/c\).

Published: January 2024

The purpose of this study is to examine the effect of Work from Home (WFH) and Job Satisfaction on the Work Productivity on Employees at Yogyakarta City Inspektorat. Data collection was done by survey method on 67 employees. Data processing was done using SEM-PLS program. Evaluation of the measurement model (outer model) with reflective indicators was evaluated by three criteria, convergent validity, discriminant validity and composite reliability. Convergent validity and discriminant validity showed that all constructs are valid, both the AVE value and the outer loading value > 0.70, while the composite reliability showed that all constructs have a composite reliability value > 0.70. The results showed that Work from Home (WFH) with job satisfaction as a mediator has a positive and significant effect on work productivity. This can be proven by the value of t statistic > 1.96 with a value of 4.358 > 1.96 and p value < 0.05 with a value of 0.000 < 0.05. So it can be concluded that Work from Home (WFH) with job satisfaction as a mediator can increase work productivity. There are two important implications in this research, first, for Inspektorat, it is necessary to regulate fair and transparent management of Work from Home (WFH) and Work from Office (WFO) so that there is no feeling of unfair treatment from employees which will affect employee satisfaction. Second, for employees to be able to maintain a balance between office and home work so that work productivity continues to increase.

Main components of the sex pheromone of fall armyworm (Spodoptera frugiperda) contain (Z)-7-dodecen-1-yl acetate (Z7-12:OAc), (Z)-9-tetradecen-1-yl acetate (Z9-14:OAc), and (Z)-11-hexadecen-1-yl acetate (Z11-16:OAc) were succesfully synthesized with a total yield over 48% via 5 steps. The starting materials for the synthesis of pheromones were diols (1,6-hexandiol; 1,8-octandiol; 10-decandiol) and 1-alkyne (1-hexyne and 1-octyne). This purpose of the study was the extension of the carbon chain by alkylation of a terminal alkyne using the n-BuLi agent and the reduction of alkyne to (Z)-alkene using the Pd(dba)2/KOH/DMF catalyst without using the molecular hydrogen. In this case, KOH/DMF was the hydrogen source system to eliminate an alkyne to (Z)-alkene and give over 90% yield with the (Z)-configuration selectivity (> 99%). The extension reaction of the carbon chain was carried out at -78oC for 30 min. and then at room temperature for 2 h., the alkyne was reduced to (Z)-alkene at 145oC for 6 hours. After the deprotection of the alcohol group by ultrasound without further purification, the acetylation was performed with an efficiency over 84%. The (Z)-alkene configuration of the obtained compounds, examined by 1H NMR spectra, showed that the coupling constants were Jcis = 11,0 Hz and Jcis = 10,5 Hz for Z11-16:OAc, respectively; but Jcis = 11,0 Hz for the Z7-12:OAc and Z9-14:OAc. This preparation process of the (Z)-alkene pheromones opened an opportunity to control fall armyworms without polluting the environment in Vietnam.

Carbon Black Masterbatch containing high carbon black content (60% by weight) was made from carbon black and a low viscosity natural rubber latex without the application of other chemical agents as well as coagulating agents. The slurry compound, after natural coagulation, was dried at 70℃ in 24h, followed by sheet shaping for next step. The Carbon Black Masterbatch was used for rubber compounding (containing 35 phr of carbon black) with natural rubber by two roll mill-mixing, and then vulcanized. Simultaneously, the reference sample was also fabricated from block natural rubber and carbon black in same compounding condition. This sample was made by directly mixing a dry natural rubber with carbon black at the same content of 35 phr of carbon black. The samples were then investigated for various characterizations for the comparison of some criteria: carbon black dispersion, vulcanization rheometer and mechanical properties (tensile strength and tear strength). The rubber sample, prepared from the masterbatch, showed the carbon black dispersion better than the ones fabricated by direct mixing method. This could be explained by the fact that carbon black was dispersed once time in Carbon Black Masterbatch. The masterbatch samples had the better properties: the curing time was shorter and the maximum torque (MH) was higher than the other sample, thank for good carbon black dispersion in the masterbatch samples. Similar results were also observed in the tensile strength and tear strength tests: samples fabricated from masterbatch possessed higher values of tensile and tear strength about 8.5% and 4.6%, respectively compared with the other sample.

Uric acid (UA) is a product of the catabolism of purine bases (adenine and guanidine) of nucleic acids that occurs naturally in the human body. The analysis of UA plays an important role in diagnosing and treating diseases such as gout, kidney stones, diabetes, heart disease, and Lesch-Nyhan syndrome. UA is analysed in the laboratory by the enzymatic colorimetric method with a time consuming of approximately one hour. Currently, electrochemical sensors are considered as a potential approach in the rapid quantification of UA due to the advantages of rapid analysis, low cost, few samples required for analysis, compact design and easy to use and do not require highly skilled technicians like traditional analytical methods. In this study, a commercial printed electrode (SPE) was surface-modified with a polyaniline-graphene (PANI-Graphene) composite coating and functionalize the surface of a PANI-Graphene film with a NiO electrochemical catalyst by cyclic voltammetry (CV) method. The fabricated electrode (designated NiO/PANI-Graphene/SPE) was used for UA analysis in a simulated human fluid medium (PBS, pH 7.4). The results show that the NiO/PANI-Graphene/SPE sensor electrode has good electrocatalytic activity for the oxidation of UA in the potential range of 0.3 to 0.5 V. Characteristically, the sensor has a wide linear range in the concentration range of 10 to 1750 μM with a high sensitivity of 29.5 μA mM-1 cm-2 and a low detection limit of 5.00 μM (S/N = 3). The NiO/PANI-Graphene/SPE sensor electrode has potential applications in the development of non-enzymatic electrochemical sensors for the rapid quantification of UA content in human body fluids.
Exploración de los recursos semántico-discursivos desde una perspectiva erótica, expresados en el poema Caperucita Roja de Gabriela Mistral
Authors: SIMUNOVIC DÍAZ HORACIO GABRIEL
Published: January 2024

El análisis del poema Caperucita Roja resulta atractivo por sí mismo, ya que su factura corrobora las cualidades inigualables de la poeta Gabriela Mistral. Sin embargo, el hecho de que sea reescritura de un cuento que remonta sus orígenes al folklore europeo y que sea mundialmente conocido por medio de sus versiones  modernas desde un punto de vista infantil: Perrault y los hermanos Grimm, vuelve la obra una curiosidad. El propósito del análisis es describir la dimensión erótica del sistema de recursos lingüístico-discursivos usados por Mistral para recrear la historia y refundar el sentido del texto original, quizá recuperando la lectura del crimen, la inocencia ultrajada y el dolor que aquel ofrecía.

DEVELOPMENT OF RAILWAY TRANSPORT INSTITUTIONS IN THE CONTEXT OF STRUCTURING AND MODERNIZATION OF THE NATIONAL ECONOMY
Authors:   International Humanitarian University (Odesa), Raicheva Larysa
Published: January 2024

The article defines the role of railway transport as a component of the transport complex of Ukraine. It is shown that the railway industry of Ukraine, as a natural monopoly, was formed on the basis of a centralized and concentrated form of state ownership in the bowels of the administrative and command system of the Soviet Union. Emphasis is placed on the problems associated with the existence of natural monopolies inherent in railway transportation. The signs of a natural monopoly on railway transport of Ukraine are systematized: the network nature of the organization of infrastructure and the provision of transport services; the presence of barriers for new business entities to enter the rail transportation market; the need for significant investments to create an alternative transport business; low investment attractiveness for private capital due to a long payback period; low elastic demand from consumers for transport services. Emphasis is placed on the problems associated with the existence of natural monopolies inherent in railway transportation. An analysis of the strengths, weaknesses, threats and development opportunities of railway transport enterprises was carried out. Measures have been developed to demonopolize railway transport of Ukraine through a justified division of the spheres of its operation into three groups: first, naturally monopolistic; secondly, areas where competition is potentially possible; third, areas where competition is natural. The conceptual principles of carrying out organizational, financial and information restructuring in railway transport based on the integration of the functional-object system and the vertical model, tariff differentiation, the spread of two-rate tariffs, the elimination of cross-subsidization, the creation of new market segments, the expansion of the spectrum of transport and related services are substantiated. The priority areas of restructuring in railway transport in the conditions of martial law and post-war reconstruction are proposed, including within the framework of the concept of socially responsible restructuring.

This empirical research identifies the possible resources as antecedents of Spirit at Work (SW) in an RBV framework. The research empirically examines 530 data taken from a leading telco company on the interaction between organizational resources in the form of spiritual leadership (SL) variables: Vision, hope/faith, altruistic love (AL), meaning/calling and membership toward SW, and human resource in the form of Individual Spirituality (IS) toward SW. Further, SW is tested toward Job Satisfaction (JS) and Organizational Commitment (OC) as competitive advantages in the Service Industry.Findings show that all work related SL variables are significant toward SW. AL shows significant influence toward SW in the context of lower IS. The SW is also significantly and positively impacting JS and OC. Vision, AL and Membership which serve as the primary role and show dependence upon organizational support, are showing higher influence toward SW in lower IS. Hope/Faith and Meaning/Calling as secondary role which rely on employees’ intrinsic factors are showing higher influence toward SW in group of higher IS.

Published: January 2024

Ecommerce blogs are increasingly popular for providing product information, reviews and driving traffic to ecommerce websites. Recent study reported 76% of ecommerce users trust online reviews as much as recommendations from family or friends. This indicates that the content found in product reviews blog plays a crucial role in driving users to ecommerce websites. This study examines the impact of content quality in beauty product review articles on click intention towards ecommerce websites. Content quality is evaluated based on Substance, Writing and Language, Presentation of Content, References, Authorship, Audience, and Advertisements. Semi-experimental and logistic regression analyses were conducted on survey data from 225 female respondents who evaluated 126 beauty product review articles. Findings indicate a positive association between Substance, Presentation of Content, and Authorship with Click Intention, while Writing and Language, References, and Advertisement show no significant correlation. Furthermore, a negative relationship exists between Audience and Click Intention. This research addresses the literature gap by identifying significant factors of content quality that influence click intention, emphasizing the importance of content quality assessment and providing strategies for improvement. The study offers valuable insights for ecommerce companies to optimize marketing expenses and achieve key performance indicators.

Hedge funds are a dynamic and heterogeneous segment of the financial industry that employs various strategies to generate returns and manage risk. Despite their growing importance and impact on the global economy, hedge funds remain largely unregulated and opaque, posing challenges for researchers and regulators alike. This paper provides a systematic review of the academic literature on hedge fund strategies, covering their institutional, historical and performance characteristics; their purpose and effectiveness in achieving balanced portfolios; and the relationship of returns to manager skill, style, size and other factors. The paper also proposes a framework for future research on hedge fund strategies.
Regarding multi models describing the driving mechanism and evolutionary process of biological phenomena
Authors: Nishida Y
Published: January 2024

Much research has been done on the evolutionary processes and general properties of life from the fields of systems biology, mathematical biology, and evolutionary biology. Life is a system in which micro and macro are coordinated and subsystems are organized to maintain metabolism and function. Life also has systems that maintain homeostasis within the body. Life adapts to time and space, responds to change, and exchanges information. In addition, the evolutionary processes and mechanisms of living systems are attempted to be elucidated from the perspective of chaos theory. Life phenomena are said to be systems that resist the law of increasing entropy by acquiring energy from the environment and generating entropy. Thus, life is a complex process in which information, energy, material interactions, dynamic systems, and environmental changes are variables. This study proposes and discusses several hypotheses that explain and generalize these mechanisms and processes. This study considers the relationship between diffusion and convergence, temporal continuity, selection and adaptability, adaptive time and space micro and macro, temporal stagnation and spatial expansion, universal properties, edges of chaos, and entropy in life phenomena. Moreover, We propose several novel hypotheses on the stochastic distribution of genomic information, its interaction with space-time probability space, and evolutionary processes in the dynamism of life phenomena, and discuss their relationship with probability statistics, fractal geometry, and chaos theory.
Quantifying soil microbial effects on plant species coexistence: a conceptual synthesis
Authors: Kandlikar Gaurav
Published: January 2024

Soil microorganisms play a critical role in shaping biodiversity dynamics in plant communities. These microbial effects can arise through direct mediation of plant fitness by pathogens and mutualists, and over the past two decades, numerous studies have shined a spotlight on the role of dynamic feedbacks between plants and soil microorganisms as key determinants of plant species coexistence. Such feedbacks arise when plants species modify the composition of the soil community, which in turn affects plant performance. Stimulated by a theoretical model developed in the 1990s, a bulk of the empirical evidence for microbial controls over plant coexistence comes from experiments that quantify plant growth in soil communities that were previously conditioned by conspecific or heterospecific plants. These studies have revealed that soil microbes can generate plant community dynamics ranging from strong negative frequency-dependence to strong positive frequency-dependence.Even as soil microbes have become recognized as a key player in determining plant coexistence outcomes, the past five years have seen a renewed interest in expanding the conceptual foundations of this field. New results include extensions of plant-soil feedback theory to multi-species communities, re-interpretations of key metrics from classic two-species models, and frameworks to integrate plant-soil feedbacks with processes like intra- and inter-specific competition. Here, I review the implications of theoretical developments for interpreting existing empirical results, and highlight proposed designs for future experiments that can reinforce key model assumptions and enable a more complete understanding of microbial regulation of plant community dynamics.

Assessing residency and dispersal behavior of apex predators and its consequences for landscape connectivity is of paramount importance for understanding population- and ecosystem- effects of anthropogenic land use change. However, basic information on animal space use is still lacking, particularly in the Tropics. Here we synthesize ranging and dispersal ecological information on pumas (Puma concolor) and present estimates of space use, dispersal, and movement of pumas in an ecotone between biodiversity hotspots in Southeastern Brazil. Using GPS data for 14 GPS-collared pumas and land use data, we assessed when, how long, and how far individuals dispersed; what factors influenced puma home range size; and how movement patterns changed according to land use and proximity to infrastructure, during residency and dispersal. We present the first detailed record on dispersal of pumas in Brazil, including long-distance dispersals, and show that pumas moved faster and less tortuously during dispersal than during residency. Pumas moved slower and had smaller home ranges in landscapes with higher proportion of forest, pointing to the importance of forests as habitat for pumas. In contrast, movement rates were higher in open pastures, mainly during dispersal and nighttime. Our study underscores the scarcity of research on puma space use and dispersal in South America and reveals divergences in dispersal behaviors compared to North America, especially concerning dispersal ages. We call for more comprehensive studies on movement ecology of carnivores combined with long-term population monitoring, to allow linking individual behavior with metapopulation dynamics and landscape connectivity and drawing more effective measures to sustain their populations.
