Carbon dioxide storage resource use trajectories consistent with US climate change mitigation scenarios
Authors: Zhang Yuting , Jackson Christopher , Darraj Nihal , Krevor Sam
Published: November 2022

To progress decarbonisation in the United States, numerous techno-economic models have been built projecting climate change mitigation scenarios that include CO2 storage deployment at annual injection rates of 0.3 – 1.7 Gt yr-1 by 2050. However, these projections do not include geological, technical, or socio-economic factors that could impede the growth of geological storage resource use. Here, we apply a growth modelling framework to evaluate CO2 storage scenarios proposed in the Net Zero America, Carbon Neutral Pathways, Long-Term Strategy, and Decarb America reports. Our modelling framework uses logistic curves to analyse the feasibility of growth trajectories under constraints imposed by the associated storage resource availability. We show that the entire storage demand for the US can be accommodated by the resources available in the Gulf Coast alone. Deployment trajectories require sustained average annual (exponential) growth at rates >10% nationally and between 3% - 20% regionally across four storage hubs. These scale-up rates are high relative to those characterising analogous, historical, large-scale energy infrastructure projects in the US (4%), suggesting that modelled projections in current reports are too aggressive in their deployment of CCS. These models could be easily constrained to more realistic deployment trajectories with the type of modelling framework we present here.

Published: November 2022

Background. Previous research, especially in educational and clinical contexts, suggests cognitive motivation (COM) in combination with self-regulation (SR) to be associated with a broad range of positive mental health, coping, and well-being indicators. Surprisingly, the interplay of these variables has rarely been considered in the occupational context. We hypothesize COM and SR to be valuable resources for counteracting health-risking stressors, which can be explained conceptually by these traits’ link to hardiness. Method. To thoroughly investigate this assumption, we analyzed data from two cross-sectional studies in Germany: a sample of 1022 psychosomatic rehabilitation in-patients (67% female) and a healthy sample of 298 employees (57% female) from various occupational sectors. Bootstrapping was used in correlation analyses and structural equation modeling (SEM). Results. In both samples, COM and SR were associated with stronger health-promoting coping with occupational demands, especially regarding an active, meaningful, and persistent coping style (.31 ≤ r ≤ .57). Analyses via SEM found COM cross-sectionally predicting occupational coping via SR in both samples. Employee’s job satisfaction was predicted via SR and stress reactions. SR predicted job performance. Exploratory analyses revealed specific aspects of job satisfaction (higher standards, problem-solving) to be especially relevant to COM and SR. Conclusion. In two independent samples, both COM and SR proofed to be personal resources closely linked to adaptive coping with everyday stressors and demands of working life. Ideas for promoting these variables in patients and employees to regain or maintain working and coping abilities will be discussed with respect to Conservation of Resources Theory.
Boys and girls, men and women: Do children take stimulus age into account when expressing gender stereotypes?
Authors: Mandalaywala Tara M , Alto Alix
Published: November 2022

Gender and age are salient social categories from early in development. However, whether children’s beliefs about gender and age intersect, such that gender stereotypes might be expressed differently when asked about children (as compared to adults) has not been investigated. Here, in a pre-registered study (N = 297), we examined if young children (3.0 – 6.9-year-olds, Mage = 5.03 years, n = 145) and adults (n = 152) across Massachusetts were more likely to express gender stereotypes when presented with child or adult stimuli. Participants were presented with 20 questions about gender stereotyped behavioral and psychological properties and selected their response (male or female) for each question by selecting between four child faces (2 White boys, 2 White girls) or four adult faces (2 White men, 2 White women) across two separate blocks. Overall, both children and adults expressed gender stereotypes above chance, and, in children, expression of stereotypes increased across the age range. Although neither children nor adults applied gender stereotypes differently to child vs. adult visual stimuli, all participants were more likely to apply gender stereotypes when that stereotype was child-centric (e.g., about doing childish activities). Our results suggest that children could be vulnerable to stereotype content from an early age; however, future research should explore whether children show this same age-invariant pattern when both gender and age are made salient and directly contrasted (e.g., by presenting men, women, boys, and girls simultaneously).
Biopsychosocial predictors of couples’ trajectories of sexual function and sexual distress across the transition to parenthood
Authors: Tavares Inês , Rosen Natalie , Heiman Julia R. , Nobre Pedro
Published: November 2022

The prevailing narrative about sexual declines during the transition to parenthood is largely based on studies assessing the average couple, but there is increasing evidence of variability in the sexual well-being of new parents. We sought to establish distinct subgroups of couples based on sexual function and sexual distress trajectories and examine biopsychosocial risk and protective factors of these trajectories. A prospective cohort of 257 first-time parent couples reported on sexual function and sexual distress from 20-weeks pregnancy (baseline) to 6-months postpartum across 4 time-points. Biopsychosocial factors were assessed at baseline and 3-months postpartum. Dyadic latent class growth analysis identified two distinct sexual function classes (high, 85%; discrepant, 15%) and three sexual distress classes (low, 77%; moderate, 12%; discrepant, 11%). We identified biomedical (vaginal delivery, perineal tear, breastfeeding) and psychosocial (fatigue, stress, anxiety, depression, attitudes towards sex during pregnancy, relationship quality, perceived partner support) factors that can be assessed at critical time-points (i.e., 20-weeks pregnancy and 3-months postpartum) to identify high-risk couples. Current results indicate that the course of change in sexual well-being for new parents is heterogenous, with most new parents retaining high function and low distress and only a minority showing trajectories in which mothers, but not fathers, experience clinically significant and persistent levels of low sexual function and high sexual distress. These results may facilitate more nuanced approaches to the assessment and intervention of new parents’ sexual well-being.
Disfunção temporomandibular e a sua relação com a Ansiedade perante o Desempenho musical em Violinistas- um estudo transversal
Authors: Rios Beatriz , Alvarelhão José , Pinheiro Ana
Published: November 2022

INTRODUCTION Temporomandibular disorder in violinists is a health condition that, in its severe forms, can have negative consequences over time. The aim of this study was to evaluate the prevalence of temporomandibular disorders in violinists and its relationship with anxiety about musical performance. METHODOLOGY A cross-sectional study was carried out on violinists from the central region of Portugal. The information was collected through an online survey. The survey included questions for sociodemographic characterization, years of study of the instrument, weekly time dedicated to the study, the disabling temporomandibular pain-screening instrument for screening for pain because of temporomandibular disorders, the index of inability to assess the impact on functionality, as well as the anxiety index towards Kenny’s musical performance. RESULTS Forty-nine violinists participated with a mean age of 27.9±9.3 years, mostly female (n=37, 75.5%). The average number of years of violin study was 17.5±7.5 years, and the average number of hours of study per week was 11.8±8.8 hours. The prevalence of temporomandibular disorders was reported by 28.6% of the participants, and a positive association was observed between the presence of temporomandibular disorders and the disability index of temporomandibular disorders (r=0.63; p<0.001), as well as with anxiety about musical performance (r=0.53; p<0.001). CONCLUSION For the sample studied, at least one in four violinists has temporomandibular disorders, which is associated with disability and anxiety about musical performance. These findings reinforce the need to sensitize instrumentalists and music teachers about the health risks, as well as the potential impact that this may have on musical performance. Future works may deepen the factors that explain the relationship between anxiety and temporomandibular disorders.

Introduction Health professionals are daily exposed to a set of demands that are often unpredictable and, consequently, have direct implications for their physical and mental health. These demands can come not only from users and family members, but also from working hours and conditions, which are difficult to control or change. According to the World Health Organization, chronic stress in the workplace leads to Burnout Syndrome. In this line of thought, one of the main concerns of Cantanhede’s Arcebispo João Crisóstomo Hospital is to seek and guarantee the general well-being of its employees and to make efforts to ensure a high level of this well-being. Objectives The main objective of this evaluation is to understand the Cantanhede’s Arcebispo João Crisóstomo Hospital health professionals’ levels of Anxiety, Depression and Burnout. Methodology Self-response instruments were used, such as the Anxiety, Depression and Stress Scale (EADS-42) and the Copenhagen Burnout Inventory (CBI) Questionnaire. These instruments were applied to professionals who voluntarily collaborated in the study. After applying them, the results were analyzed using the Statistical Package for the Social Sciences (SPSS). Results Out of the 62 employees who participated in the questionnaire, 83.9% are female and the most represented professional category is Nursing (38.7%). It should be noted that all the results obtained were considered normative/inferior when compared with the data for the Portuguese population, apart from Burnout, related to work, since it presents moderate values ​​for the male gender and moderate for Nursing professional category. Discussion/Conclusion Cantanhede Hospital has developed several strategies for Anxiety, Depression and Burnout Syndrome prevention and minimization, carrying out periodically an assessment of the health professional’s psychosocial risk. In this sense, the hospital has developed several initiatives, such as concerts, commemorative activities, more structured interventions such as yoga and mindfulness, clarification sessions on Burnout syndrome and even psychological and/or psychiatric intervention, whenever the need is identified. It is important to point out that, always aiming health professionals’ well-being, the continuity of this study is imperative, so it will be replicated in 2024. KEYWORDS Burnout Syndrome, Anxiety, Depression, Stress, Occupational Health, Occupational Medicine.

Published: November 2022

Background: Urethral stricture leads to obstructive voiding dysfunction. We report an audit of surgical management of urethral stricture in adult males.
Methods: The records of all patients diagnosed with urethral stricture from December 2017 to March 2019 at B. P. Koirala Institute of Health Sciences, Nepal were retrieved. Preoperative, surgical, and postoperative follows-up data were evaluated. The American Urological Association International Prostatic Symptom Score (AUA-IPSS) and Uroflowmetry (voided volume and peak urinary flow rate (Qmax)) were used to assess the outcome of the surgery.
Results: Among 50 patients, the majority (46%) belonged to 40 - 59 years. Twenty-five patients (78.1%) with traumatic anterior urethral stricture underwent excision and primary end to end anastomotic (EPA) urethroplasty; seven patients (21.9%) with pelvic fracture urethral injury (PFUI) underwent progressive perineal urethroplasty (PPU) with EPA; eight patients with inflammatory urethral stricture underwent Kulkarni urethroplasty; four patients with iatrogenic urethral stricture underwent EPA; six patients with idiopathic urethral stricture underwent Barbagli dorsal onlay urethroplasty. All patients had preoperative voided volume < 150ml, Qmax < 15ml/s. Thirty patients had complete obliteration; the remaining patients had severe storage and voiding symptoms (AUA-IPSS ≥ 20) before surgery. Except for two patients who underwent redo surgery, outcome of urethroplasty was successful in terms of storage and voiding symptoms (AUA-IPSS < 7) and uroflometry findings (voided volume > 150ml and Qmax >15ml/s).
Conclusion: Urethreal stricture was most common in the age group of 40 - 59 years and traumatic stricture was the most common cause.

Haiku Form in Udmurt Poetry
Authors: Shibanov Victor Leonidovich
Published: November 2022

Japanese forms of verse are beginning to occupy an important place in the Udmurt poetry of recent times. In the 1990s, the dialogue of cultures was directed mainly to the West. In the new millennium, the internal mechanisms of culture begin to actualize the classical East. There comes a time of worldview and understanding of what is happening, haiku is becoming one of the popular genres. The purpose of the study is to identify national features of the haiku genre in the Udmurt lyrics. The object of analysis is the poems of A. Leontiev, S. Matveev and Alexei Arzamazov, written in the form of a Japanese three-line poem. The method of analysis is comparative studies. The results of the study are as follows. Udmurt poets, writing in the form of haiku, strive to see the big world in a small detail, to show the eternal in a moment. The autumn landscape becomes attractive in that it conveys “light sadness” (sabi). Thus, the poets do not copy the Japanese canons, but bring a national flavor. The unexpectedness of the finale (koan) in Udmurt haiku is usually achieved by the fact that the poet passes from one spatial dimension to another.

The main requirements and risks of digital transformation of education
Authors: Rebko Olga Vasilyevna
Published: November 2022

In the context of the Fourth Industrial Revolution, the economy is in need of professionals with completely new competencies. So, the ability to make decisions based on big data, act in a situation of uncertainty, analyze and critically comprehend incoming information, etc. comes first. A modern employee is required to assimilate a new way of thinking, ethics and attitudes, the formation and development of digital culture and digital literacy. The training of such specialists becomes the most important task of education.
However, the analysis of modern research shows that teachers themselves also need tools that would allow them to effectively perform their professional duties in the new economic reality. Based on the review of the requirements and the main groups of risks caused by the digital transformation of education, we conclude that the presence of a well-developed standardized model of digital competencies of teachers can become a reliable support for teachers and teachers. Also, the introduction of such a model in the educational programs of universities and professional development programs will bring the professional training of teachers in line with the requirements of digital transformation.

Published: November 2022

As Expressões de Tempo Decorrido (ETDs) são um fenômeno de recente estudo no português brasileiro, e inédito no português alagoano em sincronia passada. Dentre as análises realizadas, grande parte tem enfoque sincrônico, investigando o português atual em suas variedades. Logo, este trabalho objetiva analisar essa variação com o aporte teórico da Sociolinguística Variacionista (LABOV, 2008 [1972]) e da Sociolinguística Histórica (ROMAINE, 1982) para explicitar os fatores condicionantes do uso desse fenômeno a partir do corpus de 112 cartas pessoais do escritor alagoano Graciliano Ramos no início do século XX. Assim, o trabalho justifica-se por ampliar as pesquisas sobre a variedade alagoana do português. Como resultado, foram encontrados 77 dados referentes às variantes “Haver” e “Fazer”, que correspondem a um percentual de 86% (66 dados) para a primeira e 14% (11 dados) para a segunda, o que motiva esse estudo a refletir sobre a ausência das variantes “Ter” e “Estar com” nas cartas. Para análise quantitativa dos dados, utilizou-se o programa RStudio, que proporcionou análises univariadas e resultou na significância das variáveis independentes aspecto (p0,05), complementizador (p0,001) e ordem (p0,001) no condicionamento das variantes das ETDs observadas. Já para análise qualitativa, observaram-se os aspectos linguísticos dos dados encontrados, o que resultou preliminarmente na constituição de hipóteses e novos caminhos de pesquisa para futuros trabalhos que investiguem o português alagoano em sua perspectiva histórica para ampliar os dados acerca desse fenômeno e verificar se a ausência de “Ter” e “Estar com” ocorre em outros corpora, além de trazer novas questões sobre as ETDs.
REPRODUCTION OF FIXED CAPITAL IN UKRAINE: SOME FEATURES AND RECOMMENDATIONS FOR PUBLIC POLICY
Authors: SHCHERBAK A.V. , SPASSKYI I.D.
Published: November 2022

Topicality. Ukraine's GDP has not reached the level of the early 1990s, and the competitiveness of the economy remains low. This is largely due to the state of the investment process. Generalized statistical data are usually used for its research. However, the situation at individual enterprises, especially in a transitional economy, is significantly different. To find out how the renewal of fixed capital takes place, to develop sound recommendations, it is necessary to analyze information concerning large groups of enterprises.Aim and tasks. The purpose of the article is to find out if there is a significant sector of enterprises with negative net investments in Ukraine. This will make it possible to give sound recommendations for improving economic policy.Research results. The article analyzes the reporting of 2.5 thousand industrial enterprises in Ukraine. It was found that more than a third of investments are in 5% of enterprises. At the same time, about 30% of them regularly make negative net investments. The existence of a significant sector of such enterprises has an extremely negative impact on the competitiveness of the national economy. It is substantiated that the main reasons for this situation are inadequate protection of property rights, a low level of competition and its unequal conditions in many markets.Conclusion. A significant reduction in the sector of enterprises with negative net investments is one of the most important conditions for increasing the competitiveness of the Ukrainian economy. This is possible as a result of reforms that will enhance competition, leveling its conditions, and reliable protection of property rights. The OECD Competition Assessment Toolkit should be used to remove anti-competitive regulations from legislation. In order to prevent a decrease in production and an increase in unemployment as a result of the bankruptcy of inefficient enterprises, it is necessary to take measures aimed at stimulating the development of the most dynamic companies and increasing their contribution to the economy, primarily by supporting gazelle firms and clusters.

Russia's Global Strategic Rebalancing: Implications for Pakistan
Authors: Malik Ahmed Ijaz , Mirza Muhammad Nadeem
Published: November 2022

Russia under Vladimir Putin’s leadership has assumed a personalised character which has drastically transformed its domestic and defence policy as well as its global grand strategy. The main contour of the grand strategy is a strategic rebalancing in the places of its influence including its near abroad and its area of interest including Asia, Asia Pacific and the Middle East. Putin’s leadership and psychological orientation have a fundamental role in the materialisation of this transformation and the study of this factor serves as a lens to explain Russia’s resurgence and also provides a guide to Russia’s future foreign policy. One of the significant aspects of the strategic rebalancing is Russia’s increasing influence in South Asia and the projects of building transport and trade corridor. While China remains another significant powerful player with similar geostrategic and geoeconomic plans; states such as Pakistan foresee great challenges as well as opportunities which emerge as a result of the increasing influence of Russia and China in the region and the lingering dissonance in Pakistan’s relations with the United States of America.
Analytical review of methods for automatic detection of user engagement in virtual communication
Authors: Dvoynikova Anastasiya , Kagirov Ildar , Karpov Alexey
Published: November 2022

Introduction: The solution of the task of the recognition and assessment of user engagement in the acts of human-machine interaction or telecommunication, achieved through the use of automatic means, is highly important in computer recognition of human psycho-emotional states. This is necessary for e-learning, business and entertainment applications design. Purpose: To conduct a comparative analysis of the current information support in the field of automatic recognition and assessment of user involvement in human-machine interaction or virtual communication, as well as to establish a methodology for building a data body based on the idea of multimodal communication. Results: The conducted analysis of research papers has shown that in most existing databases there is a substantial lack of data for natural online communication. Moreover, not all databases contain different modalities in “human-machine-human” communication system. Text and audio modalities turn out to be important for a multilevel engagement classification task, aimed at the determination of engagement intensity. It is also promising to take into account “body language” features, such as facial expressions, movements of the body and the head, gestures. For the correct assessment of involvement, an engagement database must contain meta-data on the psycho-emotional states of communicants. Neural network-based approaches to the automatic detection of user engagement show the best performance. Practical relevance: Based on the obtained analytical conclusions, the authors of the paper are going to elaborate an original software system for automatic recognition of user engagement, and to collect a data set for machine learning purposes. The presented review formulates basic requirements for such systems and contributes to the solution of the problem of automatic recognition of psycho-emotional states. Discussion: The survey leads to the conclusion that the notion of engagement as understood in studies on automatic emotion recognition differs from that used in psychology. User (or communicant) engagement in terms of info- and communicative sphere implies the manifestation of a person's mental activity level (emotional, cognitive, and behavioral components) changing dynamically while interacting with another person or computer system.
Method for accelerating the joining of distributed datasets by a given criterion
Authors: Tyryshkina Yevgeniya , Tumkovskiy Sergey
Published: November 2022

Introduction: rapidly growing volumes of information pose new challenges to modern data analysis technologies. Currently, based on cost and performance considerations, data processing is usually performed in cluster systems. One of the most common related operations in analytics is the joins of datasets. Join is an extremely expensive operation that is difficult to scale and increase efficiency in distributed databases or systems based on the MapReduce paradigm. Despite the fact that a lot of effort has been put into improving the performance of this operation, often the proposed methods either require fundamental changes in the MapReduce structure, or are aimed at reducing the overhead of the operation, such as balancing the load on the network. Objective: to develop an algorithm to accelerate the integration of data sets in distributed systems. Results: a review of the Apache Spark architecture and the features of distributed computing based on MapReduce is performed, typical methods for combining datasets are analyzed, the main recommendations for optimizing the operation of combining data are presented, an algorithm that allows you to speed up the special case of combining implemented in Apache Spark is presented. This algorithm uses the methods of partitioning and partial transfer of sets to the computing nodes of the cluster, in such a way as to take advantage of the merge and broadcast associations. The experimental data presented demonstrate that the method is all the more effective the larger the volume of input data. So, for 2Tb compressed data, acceleration up to ~37% was obtained in comparison with standard Spark SQL.
Formation of adaptive subscriptions to the Internet of things data broker
Authors: Isaeva Olga , Isaev Sergey , Kulyasov Nikita
Published: November 2022

Intoduction: the possibility of interaction with the physical world through the network infrastructures of spatially distributed nodes of Internet of Things, despite the undeniable advantages of the technology, produce significant loads on information consumers. In this regard, the current interest is the creation of methods that provide the reduction of transmitted data due to the adaptive synchronization of monitoring systems with the time of real processes. One effective way to solve this problem is to use the discrete Fourier transform to determine the sampling period of the observations. Purpose: to develop an approach to the formation of adaptive data broker subscriptions based on the study of the cyclicity of observations of Internet of Things devices. Methods: the discrete Fourier transform method was applied and, based on the calculated parameters of the harmonic series, a conclusion about the frequency characteristics of the data was made. The main peaks describing the periodicity of the data are selected, the fluctuation points are determined and, according to the Kotelnikov theorem (Nyquist-Kotelnikov-Shannon Sampling Theorem), a sampling frequency that provides a sufficient intensity of observations is chosen. Results: within the corporate network of the Krasnoyarsk Scientific Center, an infrastructure of devices and applications of the Internet of Things has been deployed to monitor temperature, humidity and PM2.5 in specialized technological rooms with telecommunications equipment. The analysis showed that for different rooms the data are periodic, but their harmonic profiles do not coincide. The choice of harmonic values, the fluctuation amplitude of which determines the dynamics of changes in the observed data, should be carried out periodically for each observed device. This approach is implemented in the broker software, which distributes data in subscriptions from each of the devices in accordance with the frequency of their changes. Practical relevance: the analysis of the frequency characteristics of the data determines the broker settings, which distributes the information flows, which is one of the aspects of reliability of the IoT infrastructure.

In addition, observing data changes will allow us to identify malfunctions in the operation of cooling systems, which can lead to the failure of complex, expensive equipment with increased heat irradiation.

One of the effective ways to solve this problem is to use blockchain technology. Purpose: Designing the architecture of a fog computing network based on blockchain technology. Results: Based on the research in the field of fog computing, the requirements for the fog computing architecture were determined, such as: autonomy, scalability, flexibility, hierarchy, security, reliability, availability, serviceability. The selected criteria for building an architecture led to the choice in favor of a private blockchain due to its higher performance compared to a public blockchain A comparative analysis of the consensus algorithms that are most often used in private blockchains was carried out and the most suitable one was chosen. Based on the requirements put forward and the results of the analysis, a fog computing architecture model based on a private blockchain was designed. The architecture consists of four elements: end devices, fog nodes, orchestration nodes, and cloud infrastructure. The blockchain includes fog nodes and orchestration nodes, which ensures the confidentiality, availability and integrity of data in the fog network. Practical relevance: Paper results can be used in the design of fog computing networks both separately and as part of 5G mobile networks.

Introduction: Internet of Things devices are actively used within the framework of Massive Machine-Type Communication scenarios. The interaction of devices is carried out by random multiple-access algorithms with limited throughput. To improve throughput one can use orthogonal preambles in the ALOHA-type class of algorithms. Purpose: To analyze ALOHA-based algorithms using the exploration phase and to calculate the characteristics for the algorithm with and without losses with a finite number of channels. Results: We have described a system model that employs random access for data transmission over a common communication channel with the use of orthogonal preambles and exploration phase. We have obtained a formula for numerical calculation of the throughput of an algorithm channel with losses with an infinite number of preambles and a given finite number of channels. The calculation results for several values of the number of independent channels are presented. A modification of the algorithm using the exploration phase and repeated transmissions is proposed and described. The system in question can work without losses. For this system, we have given the analysis of the maximum input throughput up to which the system operates stably. Also, the average delay values for the algorithm that were obtained by simulation modeling are shown. By reducing the number of available preambles, the results obtained can be used as an upper bound on the system throughput. Practical relevance: The results obtained allow to assess the potential for improving the throughput of random multiple-access systems in 6G networks through the application of the exploration phase.

At present, although the significance and advantages offered by the linkage of universities with society are recognized, there is no delimitation of the concept of linkage that favors an evaluation of its real impact and incidence on the development of the people. The objective of this article is to describe the advances that are visible in the programs of linkage with society in some universities of the Ecuadorian nation. For this purpose, it is based on a qualitative and descriptive research approach, based on the documentary bibliographic method. Different concepts related to the term "linkage" were reviewed, as well as the way of assuming and applying it in the main universities of the country. It is concluded that the universities of Ecuador show a high degree of commitment with the programs and projects of intervention and relationship with communities and business and governmental institutions with which they are linked.
STAKEHOLDER’S PERCEPTIONS OF MINING INDUSTRY IN PERU: COMMUNITY INVOLVEMENT IN DECISION-MAKING AND THEIR CAUSAL CONDITIONS

This paper studies the community involvement in decision-making on CSR investments of mining firms in Peru and its causal conditions through stakeholder’s perceptions. To this end, community members, NGOs and consultants were interviewed. The focus was on various causal conditions in which stakeholders: a) explain the community needs,  b) recognize the investments made by the companies, c) believe that mining benefits are not what they expected, d) declare the costs generated by these activities and e) point out that dialogue is the solution. Collected data were processed via a content analysis, followed by a Qualitative Comparative Analysis (QCA). The conditions which appeared in the QCA solutions were different depending on whether the community participated or not in decision-making, with the second situation prevailing. The results offer further understanding to all parties and may help companies to improve their performance.
ANÁLISIS DE PRODUCTIVIDAD Y EFICIENCIA DE LAS MIPYMES EN MÉXICO

El objetivo de este trabajo es estimar empíricamente la eficiencia y productividad de las MIPYMES en México, mediante la medición del impacto que el monto de créditos otorgado por bancos y el número de trabajadores en las MIPYMES tienen sobre el PIB que generan en el país. Para ello, se utiliza una función de producción NHPF doble logarítmica con información anual considerando como fundamento teórico de este enfoque el argumento del "dinero como insumo en la función de producción". Los resultados indican una productividad (elasticidad de salida) del trabajo positiva; la productividad del crédito bancario fue positiva, aunque menor a la unidad, y la eficiencia mejoró con retornos a escala de 1.54 a 1.65. Esto implica una mejora en la eficiencia de escala en las MIPYMES en México, principalmente debido al aumento de productividad de la fuerza laboral; aunque resulta insuficiente al considerar que ésta es requerida cada vez con mayores competencias.
ANÁLISIS DE LA RELACIÓN ENTRE EL GOBIERNO CORPORATIVO Y EL DESEMPEÑO DE LAS "BLUE CHIP" CHILENAS: UN ESTUDIO SOBRE LAS NORMAS DE "CUMPLIR O EXPLICAR"
Authors: Salamunic San Martín Luka , Moraga Flores Hugo Alejandro
Published: November 2022

La presente investigación analiza la relación entre la adopción de las prácticas de buen gobierno corporativo de las mayores empresas chilenas (“Blue Chips”) y el desempeño financiero y de las mismas. Los hallazgos incluyen correlaciones entre el gobierno corporativo y métricas financieras, específicamente, los precios transados de acciones de compañías con mejor gobierno corporativo tienen un desempeño superior a aquellas con menor adopción a éstos, particularmente para períodos de tenencia más cortos. Una posible explicación para este fenómeno es la reacción de los inversionistas institucionales ante los resultados del cuestionario oficial de prácticas de gobierno corporativo –del tipo “cumplir o explicar”– emitido en 2015 por la SVS (actual CMF).
