State Financial Regulation of Innovations in Russia under International Sanctions
Authors: Dorofeev M. L.
Published: August 2023

Relevance. One of the most vulnerable aspects of the development of the Russian economy is its technological and innovative component. This aspect of the Russian economy was tried to reanimate and increase its effectiveness after the 2008 crisis, in order to move from a raw material model of economic growth to a model of advanced technological development. In 2022, Russia has no choice but to carry out a structural transformation of the economy, for the success of which it is vital to intensify and increase the efficiency of innovation. In this regard, the role of state financial regulation of innovation activities for the transition period is increasing.

The purpose of this study is to substantiate approaches to state financial regulation of innovative development of the economy in the context of international sanctions and to clarify specific conditions for intensifying innovations in the non-state sector of the economy.

Objectives: review of the scientific literature on the impact of sanctions on the dynamics of innovative activity; analysis of innovative activity in Russia over the past 10 years; justification of the methods and instruments of state financial regulation of innovations in the current conditions for Russia.

Methodology. The article uses methods of analysis and synthesis of information, an overview analysis of scientific literature, horizontal and graphic analysis of Rosstat data on the innovative development of Russia.

Results. The results of the work was the systematization of methods and instruments of state financial regulation in the context of international sanctions, as well as the justification of specific conditions for the successful innovative development of Russia in the current geopolitical situation.

Conclusion. The Government should use a standard set of financial incentives for innovation activity, but to develop the non-governmental sector and improve the effectiveness of innovation activities, it is also necessary to create additional conditions for creating a favorable institutional environment in which appropriate private initiatives will be possible.
Religious Mysticism and the Psychology of Religion: on the Question of the Limits of Reduction. Part 2
Authors: Shugurov M. V. , Mozzhilin S. I.
Published: August 2023

Relevance. At the present stage of the development of religious studies, the importance of revealing the psychological "slice" of mysticism is increasing from the point of view of comparing two approaches – the reductionist, which reduces mysticism to intense and unusual psychological experiences, and the anti-reductionist, which sees in mysticism something more than just subjective experiences.

The purpose is to supplement the understanding of the limits of psychological reduction of religious‒mystical experience by understanding the limits of anti-reductionism.

Objectives: to determine the specifics of the approach of the Russian psychology of religion to the phenomenon of mysticism in the unity of its religious and non-religious forms; to demonstrate the content of antipsychologism as a worldview and methodological attitude of Russian religious philosophy in its approach to religious mysticism; to comprehend the boundaries of the reductionist attitude against the background of its comparison with antireductionism.

Methodology. The comparative method was used in the process of analyzing ideological attitudes (on the one hand, Western psychology of religion, and on the other – Russian psychology of religion) in the process of studying religious and mystical experience. The principle of consistency made it possible to comprehend reductionism and anti-reductionism as scientific programs that have heuristic potential only in the general space of interdisciplinary dialogue and interaction.

Results. Firstly, the heuristic value of considering religious mysticism through the prism of "genuine – inauthentic" is substantiated and the significance of demarcation of spiritual phenomena forming the three-dimensional space of religious mysticism is revealed. Russian Russian religious philosophy demonstrates the prerequisites of an antipsychological attitude within the framework of the approach of Russian religious philosophy to the phenomenon of mysticism in the unity of its religious and non-religious forms, and also defines the specifics of the Russian psychology of religion. Thirdly, the limits of the anti-reductionist approach to mystical phenomena are demonstrated.

Conclusions. In the context of the increasing influence of the neurobiological approach to the study of mysticism, new perspectives of discussion arise between the research programs of reductionism and anti-reductionism. The "boom" of neurotheology creates prerequisites for raising the question of a new composition of the interdisciplinary space for the study of religious as well as non-religious mysticism.
"Fatigue" as a Condition of Indifference of Love: Conclusions of Postmodernism
Authors: Volokhova N. V. , Filippovich J. S.
Published: August 2023

Relevance. The article examines the indifference to the experience of love. In the postmodern era, staying in the subject is regarded as an inability to independently fill oneself with important resources for life: first of all, it is important to realize oneself, anesthesia is offered by self – sufficiency against love pain, "everything will still have time, love will not run away anywhere." There is a devaluation of love, it acquires a consumer character and is supported by diagnoses as "addiction", which formulates a conclusion about its devaluation. This assumption implies the emergence of "love fatigue" as an expression of a lack or lack of attention to the basic value of a person.

The purpose of the work is to study the causes of "love fatigue" in the context of postmodernity.

Objectives: to determine the causes of "fatigue" in the manifestation of love; to characterize the phenomenon of "love" in postmodern society; to assess the impact of consumer culture on the value and significance of love and partner.

Methodology. The methodological basis of the article is the method of system analysis, which made it possible to discover modern attitudes to human relationships, in particular love, and the theoretical and methodological basis is the research of domestic and foreign philosophers and sociologists studying the problem of feelings in the postmodern era.

Results. In this paper, the concepts of "fatigue" and "love" are considered. Revealed a difference in attitude to the feeling of love in (post)modern society.

Conclusions. Existing norms allow a person to experience life experience, change its form and content, which means that the understanding of feelings and the value of relationships become unattainable for another – the boundaries become invisible. However, if a person develops the will to comprehend the other and accept him as he is, then he will free love from human limits, and therefore will enjoy time next to and development with him.
Modern Trends and Technologies of Human Resource Management
Authors: Sokur A. V. , Kolmykova T. S. , Mishchenko V. A.
Published: August 2023

The relevanceof the study is determined by the fact that the socio-economic transformations taking place in the world require a rapid adjustment of the conditions for the functioning of a business, for which human resources become a determining factor in competitiveness, which determines survival in a rapidly changing market. The study of trends and modern technologies of human resource management becomes especially relevant in such circumstances, since it allows you to identify areas for improving relations between employees and employers.

The purposeof the study is determined by the need to study modern trends in the development of human resources that affect their management technologies in modern conditions.

The objectivesof the study are as follows: to study modern approaches to the content of human resources and determine the conceptual foundations of their management; substantiate the reasons for the transition to the humanistic concept of human management; to systematize the key directions of development of human resources and technologies for their management; identify scenarios for the future development of relationships between employees and employers.

Methodologythe research methodology is based on the methods of logical and comparative analysis, data grouping, the method of expert assessments, modeling and forecasting.

The resultsof the study show that the modern concept of human resource management is being transformed, realizing the transition from the organizational and social to the humanistic concept of human management. The modern business strategy is defined by the functionality of human resource management from the position of recognizing the abilities and talents of a person as a special object of management. The work reveals a set of reasons that led to the transformation of managerial functions: the predominance in the 21st century of the format for describing the decisionmaking environment BANI instead of VUCA; digitalization of most of all processes and phenomena surrounding a person; high mobility of workers and their commitment to the idea of lifelong education. Taking into account these patterns, the study identified basic trends in human resource management, which are grouped into three blocks: socio-economic and organizational, managerial-technological and humanitarian-behavioral. Based on expert assessments, scenarios for the development of human resources have been developed from the point of view of their interaction with employers under the influence of factors of a growing supply of talents and the regulatory role of the state.

Conclusions:the conclusions obtained as a result of the study indicate that the growing complexity of the modern world requires a transition to the maximum variability of human resource management scenarios and the rejection of universal technologies, for which there is no place left in modern conditions of unpredictability.

Authors: Chen Nai-Jung , Huang Chiu-Mieh , Fan Ching-Chih , Lu Li-Ting , Lin Fen-He , Liao Jung-Yu , Guo Jong-Long
Published: August 2023

Background

Artificial intelligence–driven chatbots are increasingly being used in health care, but few chat-based instant messaging support health education programs are designed for patients with chronic kidney disease (CKD) to evaluate their effectiveness. In addition, limited research exists on the usage of chat-based programs among patients with CKD, particularly those that integrate a chatbot aimed at enhancing the communication ability and disease-specific knowledge of patients.

Objective

The objective of this formative study is to gather the data necessary to develop an intervention program of chat-based instant messaging support health education for patients with CKD. Participants’ user experiences will form the basis for program design improvements.

Methods

Data were collected from April to November 2020 using a structured questionnaire. A pre-post design was used, and a total of 60 patients consented to join the 3-month program. Among them, 55 successfully completed the study measurements. The System Usability Scale was used for participant evaluations of the usability of the chat-based program.

Results

Paired t tests revealed significant differences before and after intervention for communicative literacy (t54=3.99; P<.001) and CKD-specific disease knowledge (t54=7.54; P<.001). Within disease knowledge, significant differences were observed in the aspects of CKD basic knowledge (t54=3.46; P=.001), lifestyle (t54=3.83; P=.001), dietary intake (t54=5.51; P<.001), and medication (t54=4.17; P=.001). However, no significant difference was found in the aspect of disease prevention. Subgroup analysis revealed that while the findings among male participants were similar to those of the main sample, this was not the case among female participants.

Conclusions

The findings reveal that a chat-based instant messaging support health education program may be effective for middle-aged and older patients with CKD. The use of a chat-based program with multiple promoting approaches is promising, and users’ evaluation is satisfactory.

An Artificial Intelligence Model for Predicting Trauma Mortality Among Emergency Department Patients in South Korea: Retrospective Cohort Study
Authors: Lee Seungseok , Kang Wu Seong , Kim Do Wan , Seo Sang Hyun , Kim Joongsuck , Jeong Soon Tak , Yon Dong Keon , Lee Jinseok
Published: August 2023

Background

Within the trauma system, the emergency department (ED) is the hospital’s first contact and is vital for allocating medical resources. However, there is generally limited information about patients that die in the ED.

Objective

The aim of this study was to develop an artificial intelligence (AI) model to predict trauma mortality and analyze pertinent mortality factors for all patients visiting the ED.

Methods

We used the Korean National Emergency Department Information System (NEDIS) data set (N=6,536,306), incorporating over 400 hospitals between 2016 and 2019. We included the International Classification of Disease 10th Revision (ICD-10) codes and chose the following input features to predict ED patient mortality: age, sex, intentionality, injury, emergent symptom, Alert/Verbal/Painful/Unresponsive (AVPU) scale, Korean Triage and Acuity Scale (KTAS), and vital signs. We compared three different feature set performances for AI input: all features (n=921), ICD-10 features (n=878), and features excluding ICD-10 codes (n=43). We devised various machine learning models with an ensemble approach via 5-fold cross-validation and compared the performance of each model with that of traditional prediction models. Lastly, we investigated explainable AI feature effects and deployed our final AI model on a public website, providing access to our mortality prediction results among patients visiting the ED.

Results

Our proposed AI model with the all-feature set achieved the highest area under the receiver operating characteristic curve (AUROC) of 0.9974 (adaptive boosting [AdaBoost], AdaBoost + light gradient boosting machine [LightGBM]: Ensemble), outperforming other state-of-the-art machine learning and traditional prediction models, including extreme gradient boosting (AUROC=0.9972), LightGBM (AUROC=0.9973), ICD-based injury severity scores (AUC=0.9328 for the inclusive model and AUROC=0.9567 for the exclusive model), and KTAS (AUROC=0.9405). In addition, our proposed AI model outperformed a cutting-edge AI model designed for in-hospital mortality prediction (AUROC=0.7675) for all ED visitors. From the AI model, we also discovered that age and unresponsiveness (coma) were the top two mortality predictors among patients visiting the ED, followed by oxygen saturation, multiple rib fractures (ICD-10 code S224), painful response (stupor, semicoma), and lumbar vertebra fracture (ICD-10 code S320).

Conclusions

Our proposed AI model exhibits remarkable accuracy in predicting ED mortality. Including the necessity for external validation, a large nationwide data set would provide a more accurate model and minimize overfitting. We anticipate that our AI-based risk calculator tool will substantially aid health care providers, particularly regarding triage and early diagnosis for trauma patients.
Challenging the Portrait of the Unhealthy Gamer—The Fitness and Health Status of Esports Players and Their Peers: Comparative Cross-Sectional Study (Preprint)
Authors: Ketelhut Sascha , Bodman Alex , Ries Thomas , Nigg Claudio R
Published: August 2023

BACKGROUND

Esports players are often referred to as sedentary athletes, as gaming requires prolonged sedentary screen exposure. As sedentary behavior and physical inactivity are major causes of noncommunicable diseases and premature death, esports players may be at an increased risk for health implications. Prior research has established esports players as having higher levels of body fat and lower levels of lean body mass versus age-matched controls, suggesting the need to assess further health and fitness outcomes of this demographic. However, while research interest is undoubtedly increasing, the majority of studies has focused on subjective self-report data and has lacked relevant objective health and fitness measurements.

OBJECTIVE

This study aimed to assess the health and fitness status of a group of competitive esports players in relation to an age- and sex-matched comparison group.

METHODS

In total, 51 competitive esports players (mean 23, SD 3 years, 2 female) and 51 nonesports players (mean 24, SD 3 years, 2 female) were enrolled in this cross-sectional laboratory study. The esports players and the nonesports players completed a questionnaire assessing demographic data and self-reported physical activity levels. Furthermore, physical parameters including BMI, waist-to-height ratio, body fat percentage, systolic blood pressure, diastolic blood pressure, pulse wave velocity, maximal grip strength, and maximal oxygen consumption were assessed.

RESULTS

There were no significant differences in BMI (t100=1.54; P=.13; d=0.30), waist-to-height ratio (t100=1.44; P=.16; d=0.28), body fat percentage (t100=−0.48; P=.63; d=−0.09), systolic blood pressure (t100=−0.06; P=.93; d=−0.01), diastolic blood pressure (t100=0.37; P=.71; d=0.07), pulse wave velocity (t93=−2.08; P=.15; d=−0.43), maximal grip strength (t100=−.08; P=.94; d=−0.02), maximal oxygen consumption (t100=−0.11; P=.92; d=−0.02), and physical activity (PA) levels (t86=2.17; P=.08; d=0.46) between the groups.

CONCLUSIONS

While the health narrative directed toward esports players has been mainly negative, this laboratory-based study indicated that esports players are not less healthy or fit compared to their peers. However, it seems that esports players are very heterogeneous and seem to span across the whole range of the fitness and health spectrum. Thus, the generalized statements of the esports athlete as an obese and unhealthy individual may need to be reconsidered.
The Use of a Decision Support System (MyFood) to Assess Dietary Intake Among Free-Living Older Adults in Norway: Evaluation Study (Preprint)
Authors: Severinsen Frida , Andersen Lene Frost , Paulsen Mari Mohn
Published: August 2023

BACKGROUND

The proportion of older adults in the world is constantly increasing, and malnutrition is a common challenge among the older adults aged ≥65 years. This poses a need for better tools to prevent, assess, and treat malnutrition among older adults. MyFood is a decision support system developed with the intention to prevent and treat malnutrition.

OBJECTIVE

This study aimed to evaluate the ability of the MyFood app to estimate the intake of energy, protein, fluids, and food and beverage items among free-living older adults aged ≥65 years, primarily at an individual level and secondarily at a group level. In addition, the aim was to measure the experiences of free-living older adults using the app.

METHODS

Participants were instructed to record their dietary intake in the MyFood app for 4 consecutive days. In addition, each participant completed two 24-hour recalls, which were used as a reference method to evaluate the dietary assessment function in the MyFood app. Differences in the estimations of energy, protein, fluid, and food groups were analyzed at both the individual and group levels, by comparing the recorded intake in MyFood with the 2 corresponding recalls and by comparing the mean of all 4 recording days with the mean of the 2 recalls, respectively. A short, study-specific questionnaire was used to measure the participants’ experiences with the app.

RESULTS

This study included 35 free-living older adults residing in Norway. Approximately half of the participants had ≥80% agreement between MyFood and the 24-hour recalls for energy intake on both days. For protein and fluids, approximately 60% of the participants had ≥80% agreement on the first day of comparison. Dinner was the meal with the lowest agreement between the methods, at both the individual and group levels. MyFood tended to underestimate the intake of energy, protein, fluid, and food items at both the individual and group levels. The food groups that achieved the greatest agreement between the 2 methods were eggs, yogurt, self-composed dinner, and hot beverages. All participants found the app easy to use, and 74% (26/35) of the participants reported that the app was easy to navigate.

CONCLUSIONS

The results showed that the MyFood app tended to underestimate the participants’ dietary intake compared with the 24-hour recalls at both the individual and group levels. The app’s ability to estimate intake within food groups was greater for eggs, yogurt, and self-composed dinner than for spreads, mixed meals, vegetables, and snacks. The app was well accepted among the study participants and may be a useful tool among free-living older adults, given that the users are provided follow-up and support in how to record their dietary intake.
Public Perceptions and Discussions of the US Food and Drug Administration's JUUL Ban Policy on Twitter: Observational Study (Preprint)
Authors: Liu Pinxin , Lou Xubin , Xie Zidian , Shang Ce , Li Dongmei
Published: August 2023

BACKGROUND

On June 23, 2022, the US Food and Drug Administration announced a JUUL ban policy, to ban all vaping and electronic cigarette products sold by Juul Labs.

OBJECTIVE

This study aims to understand public perceptions and discussions of this policy using Twitter (subsequently rebranded as X) data.

METHODS

Using the Twitter streaming application programming interface, 17,007 tweets potentially related to the JUUL ban policy were collected between June 22, 2022, and July 25, 2022. Based on 2600 hand-coded tweets, a deep learning model (RoBERTa) was trained to classify all tweets into propolicy, antipolicy, neutral, and irrelevant categories. A deep learning model (M3 model) was used to estimate basic demographics (such as age and gender) of Twitter users. Furthermore, major topics were identified using latent Dirichlet allocation modeling. A logistic regression model was used to examine the association of different Twitter users with their attitudes toward the policy.

RESULTS

Among 10,480 tweets related to the JUUL ban policy, there were similar proportions of propolicy and antipolicy tweets (n=2777, 26.5% vs n=2666, 25.44%). Major propolicy topics included “JUUL causes youth addition,” “market surge of JUUL,” and “health effects of JUUL.” In contrast, major antipolicy topics included “cigarette should be banned instead of JUUL,” “against the irrational policy,” and “emotional catharsis.” Twitter users older than 29 years were more likely to be propolicy (have a positive attitude toward the JUUL ban policy) than those younger than 29 years.

CONCLUSIONS

Our study showed that the public showed different responses to the JUUL ban policy, which varies depending on the demographic characteristics of Twitter users. Our findings could provide valuable information to the Food and Drug Administration for future electronic cigarette and other tobacco product regulations.

UNSTRUCTURED

The potential and threat of digital tools to achieve health equity has been highlighted for over a decade, but the success of achieving equitable access to health technologies remains challenging. Our paper addresses renewed concerns regarding equity in digital health access that were deepened during the COVID-19 pandemic. Our viewpoint is that (1) digital health tools have the potential to improve health equity if equitable access is achieved, and (2) improving access and equity in digital health can be strengthened by considering behavioral science–based strategies embedded in all phases of tool development. Using behavioral, equity, and access frameworks allowed for a unique and comprehensive exploration of current drivers of digital health inequities. This paper aims to present a compilation of strategies that can potentially have an actionable impact on digital health equity. Multilevel factors drive unequal access, so strategies require action from tool developers, individual delivery agents, organizations, and systems to effect change. Strategies were shaped with a behavioral medicine focus as the field has a unique role in improving digital health access; arguably, all digital tools require the user (individual, provider, and health system) to change behavior by engaging with the technology to generate impact. This paper presents a model that emphasizes using multilevel strategies across design, delivery, dissemination, and sustainment stages to advance digital health access and foster health equity.

Published: August 2023

The Kidney Precision Medicine Project (KPMP) aims to create a kidney tissue atlas, define disease subgroups, and identify critical cells, pathways, and targets for novel therapies through molecular investigation of human kidney biopsies obtained from participants with AKI or CKD. We present the case of a 66-year-old woman with diabetic kidney disease who underwent a protocol KPMP kidney biopsy. Her clinical history included diabetes mellitus complicated by neuropathy and eye disease, increased insulin resistance, hypertension, albuminuria, and relatively preserved glomerular filtration rate (early CKD stage 3a). The patient's histopathology was consistent with diabetic nephropathy and arterial and arteriolar sclerosis. Three-dimensional, immunofluorescence imaging of the kidney biopsy specimen revealed extensive periglomerular neovascularization that was underestimated by standard histopathologic approaches. Spatial transcriptomics was performed to obtain gene expression signatures at discrete areas of the kidney biopsy. Gene expression in the areas of glomerular neovascularization revealed increased expression of genes involved in angiogenic signaling, proliferation, and survival of endothelial cells, as well as new vessel maturation and stability. This molecular correlation provides additional insights into the development of kidney disease in patients with diabetes and spotlights how novel molecular techniques used by the KPMP can supplement and enrich the histopathologic diagnosis obtained from a kidney biopsy.
Exploring the Effects of Corpus-Based Cross-Border E-Commerce Writing Instruction for Vocational College EFL Learners
Authors: Liu Jing
Published: August 2023

This study proposed and implemented corpus-based writing instruction via the use of a custom-made corpus learning platform for learners of cross-border e-commerce English in the context of vocational colleges. It attested the effects of the proposed DDL pedagogy versus conventional PPP teaching practice on 83 e-commerce majors at a vocational college randomly forming a control group and an experimental group respectively. The experimental group received a three-step inductive pedagogical approach enabled by a tailer-made corpus learning platform while the control group was taught by conventional PPP teaching practice. Results indicated that the experimental group outperformed the control group in writing product description which is a language skill essential to cross-border e-commerce operation. Findings of this research can be interpreted as suggestive that it’s worthwhile to apply custom-made specialized corpora and corpus-based teaching pedagogy to facilitate ESP learning for EFL learners at vocational colleges.
Primer reporte de una combustión lenta residual en el volcán Quinceo, Morelia, Michoacán (México)

Published: August 2023

En el presente trabajo se documenta la presencia de un fenómeno de combustión latente residual (CLR) reportado el 30 de abril del 2022 en el volcán Quinceo, Morelia. Para identificar los gases difusos emanados, el 14 de mayo se realizaron mediciones de los flujos y concentraciones de metano (CH4), dióxido de carbono (CO2) y sulfuro de hidrógeno (H2S) en 25 sitios con la cámara de acumulación de gases. Adicionalmente se determinó la concentración de monóxido de carbono (CO) amoniaco (NH3) y oxígeno (O2) en ésos mismos sitios con un detector de gases múltiples ALTAIR 5X y se midió la temperatura del subsuelo (15 cm de profundidad) mediante un termopar. Los resultados mostraron que las temperaturas más altas registradas en el subsuelo fueron de hasta 341 °C, donde no fue posible determinar los flujos por la inestabilidad del equipo debido a la temperatura elevada. El cálculo del coeficiente de correlación mostró una relación positiva entre la temperatura y la concentración de H2S, CH4 y NH3. El bajo flujo de metano y el límite inferior de explosividad (LIE) no detectado en la mayoría de los sitios medidos, indican bajo riesgo de explosividad. Sin embargo, hay una zona donde confluyen condiciones tales como las altas temperaturas en el subsuelo, altos flujos de gases, elevadas concentraciones de CH4 y O2 y un LIE entre 7 a 10 %, que indican un riesgo de explosividad muy focalizado. La evaluación del riesgo de una explosión en la zona por la falla en el ducto de la tubería de gas natural localizado a unos metros de la zona de CLR, estimó que podría causar daño hasta una distancia de 250 m. Adicionalmente, los altos niveles de metano en esta zona, representan una fuente importante de producción de gases de efecto invernadero. Es posible que este fenómeno (CLR) haya sido provocado por un incendio forestal reportado el 30 de abril, cuyas condiciones de desertificación del lugar como el tipo de suelo (Feozem, rico en materia orgánica) y condiciones ambientales (temperaturas máximas para el mes de mayo de 31 °C), aumentan los riesgos de una explosión del gasoducto.
Assessment of contamination level of watercourses and streambed sediments downstream the Capillitas Mine, Catamarca, Argentina
Authors: Do Campo Margarita , Valenzuela María Fernanda , Ferro Leonardo
Published: August 2023

The present study constrain the degree of contamination by heavy metals and metalloids of streams impacted by mining activities in Capillitas Mine (Catamarca, Argentina), an epithermal precious- and base-metal vein deposit previously mined for copper along with gold and silver; and subsequently for rodhochrosite. Geochemical analyses of water of three streams (Ortíz, Acid and Capillitas) and a small pond depicting a very thin layer of turquoise-colored precipitates in its bottom were performed and the environmental risk factor was calculated. Moreover, the concentrations of potential toxic elements in sediments from the Ortíz and Capillitas streams were determined by ICP-OES and the Index of geoacumulation (Igeo) for As, Cd, Zn, Cu, Mn and Pb was computed.

According to their major ions concentration the four water samples correspond to calcium SO4 waters. The Acid and Ortíz streams and the turquoise pond show concentrations of Al, Mn, Cd, Zn, Cu, Cr, Ni and Pb that largely exceed the limiting concentrations for protection of aquatic life, as well as for irrigation waters. The Capillitas stream has a lower content of heavy metal but shows concentrations of Mn, Zn, Cu and Pb exceeding the limiting values for protection of aquatic life. 

According to the obtained Igeo the three streambed sediments from the Ortíz creek are extremely polluted for Cd, Zn and Pb, whereas they range from strongly to extremely polluted for Cu, As and Mn. The sediments from Capillitas creek depict lower contents of metals and metalloids; though it is strongly polluted for Cd, moderately polluted for Cu and unpolluted to moderately polluted for Pb and Zn.
Parameter calibration of stochastic volatility Heston’s model: constrained optimization vs. differential evolution
Authors: Ortiz Ramírez Ambrosio , Venegas Martínez Francisco , Martínez Palacios María Teresa Verónica
Published: August 2023

This paper calibrates through loss functions the parameters of Heston’s stochastic volatility model by using two different methods: minimizing a nonlinear objective function (a loss function) with constraints on the values of the parameter and using a differential evolution algorithm. Both methods are applied to implied volatilities on the Mexican Stock Exchange Index with four maturities and twenty-eight strike prices. The selection criterion for the parameters is minimizing the value of the mean square error of the implied volatility. The first method has a better performance with less error and time. However, empirical results show that for both methods the adjustment of implied volatilities is better for options with long-term maturities than for short-term maturities.

Authors: Luna Espinoza Ignacio , Torres Fragoso Jaime
Published: August 2023

El objetivo de esta investigación es evaluar la calidad de los servicios públicos de salud en el Istmo de Tehuantepec, tomando como estudio de caso las unidades de salud que operan en uno de los municipios estratégicos de la región, pues ahí se atienden a derechohabientes provenientes de municipios urbanos y rurales. Para ello se aplicó una versión modificada del modelo SERVPERV, el cuál captura las percepciones de los usuarios con base en cinco criterios: fiabilidad, capacidad de respuesta, seguridad, empatía y elementos tangibles. La consistencia interna y validez del instrumento se corroboraron mediante el alfa de Cronbach y análisis factorial confirmatorio, respectivamente. Se encontró que el IMSS obtuvo las mejores valoraciones, superando al Centro de Salud y al Hospital General; el ISSSTE obtuvo las notas más bajas. Adicionalmente, la edad, escolaridad y ocupación son variables que influyen en la valoración de los servicios de salud.
Factores determinantes de la consolidación empresarial: un enfoque integrador desde el emprendedor, la empresa y el entorno
Authors: Arango Benjumea Jhon Jaime
Published: August 2023

El presente estudio propone un enfoque para determinar la consolidación empresarial desde la integración de factores asociados al emprendedor, la empresa y el entorno, mediante la reducción de factores, el modelo estructural y la bondad de ajuste, a través de los cuales se pudo corroborar tres hipótesis de relación y tres hipótesis de correlación entre factores. El estudio empírico se realizó sobre una muestra de 212 empresarios de diversos países latinoamericanos. Los resultados indican que la consolidación empresarial está determinada desde el emprendedor por la perseverancia, el liderazgo, la identidad y las decisiones; desde la empresa por la estrategia, la innovación, el personal, el mercado y la rentabilidad; y desde el entorno por la financiación, la competencia, las redes, el crecimiento y los contactos.

El objetivo de este estudio fue evaluar dos modelos Path considerando el contrato psicológico y la percepción de apoyo/traición organizacional, como predictores del burnout y la intención de renuncia. Participaron 353 trabajadores en la Ciudad de México. Los dos modelos mostraron índices de ajuste aceptable: 1) En el modelo de relación de intercambio psicosocial saludable, si los empleadores proporcionan: a) capacitación y ayuda, b) lealtad y apoyo, c) desarrollo y d) seguridad laboral; aumentará el rendimiento, y disminuirá el burnout y las intenciones de renuncia; 2) En el modelo de relación de intercambio de riesgo psicosocial cuando los empleadores: a) disminuyen la calidad de vida laboral, b) generan desconfianza y traición, c) limitan al trabajador, y d) disminuyen garantías laborales; generarán desesperanza y desconfianza en el trabajador, aumentando el burnout y las intenciones de renuncia. Las organizaciones deben considerar el efecto de la dinámica de la relación empleador-empleado sobre la salud psicosocial de los trabajadores.

Los resultados del efecto de las tecnologías de la información (TI) en el rendimiento organizacional han sido contradictorios, por ello se han propuesto variables intervinientes para determinar su efecto, sobre todo en pymes de países con economía emergente, puesto que las inversiones en TI son altas. El propósito de este artículo es analizar el efecto de las capacidades TI en el rendimiento organizacional, a través de la alineación estratégica de las tecnologías, el aprendizaje organizacional y la agilidad de procesos, en pymes del estado de Tamaulipas, México. A partir de la revisión de la literatura se desarrolló un modelo de investigación y un instrumento de medición. Se recopilaron 388 cuestionarios a dueños o gerentes de pymes. Para el análisis se utilizó la técnica estadística de modelado de ecuaciones estructurales. Lo resultados permiten detectar que las capacidades TI son factores relevantes que se deben considerar por su efecto tanto en las capacidades organizacionales como en su rendimiento organizacional, lo que ayuda a los dueños o gerentes de las pymes, a reconocer áreas potenciales donde invertir, para optimizar o habilitar sus capacidades TI en apoyo de un mejor manejo de procesos y de clientes.

El objetivo de este trabajo es analizar el impacto de la apertura económica en la formación de capital y los encadenamientos intersectoriales. Con este fin, evaluamos empíricamente el impacto de las exportaciones y la inversión extranjera directa (IED) en el acervo de capital y la capacidad de arrastre/dispersión a nivel multisectorial en México durante el periodo 1999-2020. Nuestros principales resultados sugieren que: i) un aumento de las exportaciones y la inversión externa no propició un incremento en el acervo de capital; ii) uno de los efectos de la IED fue la fragmentación de la mayoría de los subsectores locales y la falta de inserción internacional; iii) no existe una relación estadísticamente significativa entre la IED y los encadenamientos hacia adelante; y, por último, encontramos una relación negativa entre las variaciones de la productividad/competitividad y la formación de capital.
¿Se ha hecho lo suficiente y lo necesario? O ¿lo necesario no ha sido suficiente?

Many factors affect the nutritional status of children. The insufficient intake of protein and/or calories, necessary to meet the nutritional needs of the child's body, unfortunately sometimes responds to the social conditions of the country. While WHO aspires to eliminate all forms of malnutrition from the world, and for all populations to enjoy health and well-being, the reality is that much remains to be done.
Elección de pareja: implicaciones y complicaciones

Human individualistic loneliness impels us to live as a couple and to achieve male/female complementarity, affection, and reciprocity. The scientific journalism of this article paraphrases the content of its bibliography when reviewing the choice of a partner, its satisfaction and complications and preventive instruction of circumstances that cause rupture. The flaw, since the election, ignores the mechanisms between reason and sexual instinct. The problem of love is not to be loved but to develop such a capacity, since maladjustment and monotony extinguishes it. The elector/chosen act and its simultaneous reasons are described: conscious (homogeneity/heterogeneity of the encounter; emulation of the animal model; type, link dynamics and social networks; sociodemographic aspects; geographic location and accessibility; sexual sharing and immediate/future expectations), and unconscious (election problems, dyadic interaction and parental history; defense mechanisms, exchange of dissociations; idealization; negative reciprocity, power struggle, projective identification, search for appreciation for the other; narcissism, false self, delay/avoidance mechanisms liability, insecurity, trespass and collusion). A healthy couple understands/attends to the creation and maintenance of ""we"", eliminates the power struggle and produces permanent conciliation. Agreement and tolerant understanding are essential for a satisfactory, stable, and lasting emotional relationship.
Keywords: Choice of partner; conscious/unconscious reasons; “we”; power struggle; conciliation
CNN Based Forest Fire Monitoring System

Abstract: As a type of natural resource, forests are vital for our existence. Wildfires are a significant threat to humans and other living beings, with the development of satellite technology it can be continuously monitored and controlled. Accurate real-time monitoring of wildfires is not only an important part of forest fire prevention, but also an important means of effectively controlling the spread of wildfires and reducing economic losses. Therefore, we need a highly mobile early forest fire warning system to ensure the safety of forest resources. In view of this, we propose a forest fire monitoring method that uses convolutional neural network to detect fire from images which can monitor the presence of fire in the forest arena.
A Study on the Improvement of Pre-negotiation System to Improve Public Contribution in Private Development

In the case of idle land in the city center or a site that has lost the function of the existing land, it is difficult to develop it as an existing use area. Therefore, it is necessary to induce development by changing the use area of the site through prior negotiations, and to provide some of the profits from the development as public contributions. Therefore, this study seeks to find improvement plans by examining various problems and obstacles that occur during the negotiation process of the pre-negotiation system for public contribution and the process of negotiation implementation. First, various problems and solutions emerged from prior research related to the pre-negotiation system and public contributions were derived to extract various obstacles that could arise from pre-negotiation of urban planning changes. Second, FGI was conducted through a survey of experts, and then AHP analysis was conducted. Third, the factors for improving public contribution were first extracted and classified, then added and removed through discussion with a number of experts in the relevant field, and the final factors for improvement were selected. The final improvement factors for the study were summarized by re-examining whether there were any missing parts.
An empirical analysis of the effect of the real estate holding ratio of domestic listed companies on the company's excess performance and risk by source
Authors:   Residential Environment Institute Of Korea, Jung Wan Sung

In this study, the risk-adjusted model (RAM: Risk Adjusted Model) was used to calculate excess performance of the seven sub-industries for 10 years from 2013 to 2022. In the analysis of the achievement of excess performance according to real estate ownership ratio, it was found that when real estate ownership ratio increases, high excess performance ratios are achieved in the business facility management and construction industries, while poor excess performance is achieved in the transportation, manufacturing industries. In the case of the wholesale and retail KOSPI, it shows high performance with a high real estate ownership ratio because of positive effect on core competencies due to the nature of the wholesale and retail business. When the excess performance ratio was low, the real estate ownership ratio increases the non-systematic at a greater extent. It can be inferred that real estate holding increases the non-systematic risk of a company. The reason of underperformance of the transportation, manufacturing industries is due to the greater increase in non-systematic risk than other industries when real estate ownership ratio increases.
Quantum-assisted Monte Carlo algorithms for fermions
Authors: Xu Xiaosi , Li Ying
Published: August 2023

Quantum computing is a promising way to systematically solve the longstanding computational problem, the ground state of a many-body fermion system. Many efforts have been made to realise certain forms of quantum advantage in this problem, for instance, the development of variational quantum algorithms. A recent work by Huggins et al. [1] reports a novel candidate, i.e. a quantum-classical hybrid Monte Carlo algorithm with a reduced bias in comparison to its fully-classical counterpart. In this paper, we propose a family of scalable quantum-assisted Monte Carlo algorithms where the quantum computer is used at its minimal cost and still can reduce the bias. By incorporating a Bayesian inference approach, we can achieve this quantum-facilitated bias reduction with a much smaller quantum-computing cost than taking empirical mean in amplitude estimation. Besides, we show that the hybrid Monte Carlo framework is a general way to suppress errors in the ground state obtained from classical algorithms. Our work provides a Monte Carlo toolkit for achieving quantum-enhanced calculation of fermion systems on near-term quantum devices.
