Authors: Ishengoma Fredrick R.
Published: May 2023

Artificial intelligence (AI) is transforming the healthcare system at a breakneck pace by improving digital healthcare services, research, and performance, fueled by the combination of big data and strong machine learning algorithms. As a result, AI applications are being employed in digital healthcare domains of which some where previously regarded as only done by human expertise. However, despite AI's benefits in digital healthcare services, issues and ethical concerns need to be addressed. Using mapping review methodology, a taxonomy of issues and ethical concerns surrounding the employment of AI in healthcare is presented and discussed. Moreover, policy recommendations and future research directions are presented.

Fostering sustainable cities through additional SDG11-related indicators
Authors: Lami Isabella M. , Abastante Francesca , Gaballo Marika , Mecca Beatrice , Todella Elena
Published: May 2023

Within a global strategy for the pursuit of Sustainable Development, the governments are responsible for following, developing, and reviewing the 2030 Agenda at global, national, and regional levels. However, it is possible to observe a lack, acknowledged by the scientific debate, of effective implementation of Sustainable Development Goals (SDGs). In this context, the paper intends to contribute to addressing this gap in methodological and operational terms, focusing on SDG11, and more specifically on two of its targets: 11.1 (Affordable Housing) and 11.3 (Inclusive and Sustainable Urbanization). In this sense, the research focuses on cities as crucial points of intervention to tackle global challenges since they represent the places with greatest concentration of population. This paper proposes a new set of indicators for monitoring targets 11.1 and 11.3 of SDG11 capable of supporting public policymakers in observing the Italian territory. More specifically, the research provides: i) the state of the art of the existing indicators of the targets in analysis; ii) the selection criteria and gaps to be considered for reviewing indicators; iii) the modalities of implementation; iv) a new set of indicators to support the development of urban policies.
Temporary housing in Turin: the Ma.Ri. House case study
Authors: Caruso Nadia , Datola Giulia
Published: May 2023

This paper illustrates the application of a multi- methodological approach based on the sequential application of three different techniques for assessing the multidimensional impacts generated by the realization of the Ma.Ri. House temporary housing, located in the city of Turin. The applied methodologies are (1) SWOT analysis for the preliminary examination of the project context, to highlight its strengths, weaknesses, opportunities and threats, which are fundamental elements to be considered for the definition of the project strategy, (2) Stakeholder Analysis to identify the multiplicity of stakeholder involved and affected by the Ma.Ri. House project, highlighting their different interests, (3) Community Impact Evaluation (CIE) for the assessment of the nature and intensity of the possible multidimensional impacts derived from the project implementation that could affect the stakeholder involved. Therefore, this paper aims to investigate local housing policy, which is a complex, multi-actorial and social relevance issue. The proposed methodological framework aims to support decision-makers in identifying a strategy that considers the different interests and maximizes the positive impacts for the different stakeholder involved. Specifically, the proposed methodological approach has been applied to evaluate the preliminary stage of the implementation of the temporary housing Ma.Ri. House.
Sustainability assessment in the authorisation process of urban transformation: the meta-design of a GeoBIM platform
Authors: Della Scala Valerio , Quaglio Caterina
Published: May 2023

The assessment criteria and indicators used in the authorisation processes of building or urban projects can play a key role in achieving the goals introduced by the UN 2030 Agenda for Sustainable Development. Yet, on the one hand, the evaluation of project proposals and the granting of building permits still rely to a large extent on the subjective judgement of public technicians, severely limiting the incentive for the development of virtuous practices and innovative procedures; on the other hand, the measurement of the SDGs on a local basis presents strong operational gaps and criticalities, struggling to clearly orientate urban transformation processes. In the paper, these problematic issues represent the starting point to discuss the possibilities that the development of a GeoBIM platform could open to spatialise, measure and automate authorisation processes by integrating local regulations and sustainability indicators of global significance. The methodological and technical implications of the proposal are explored both through a reconstruction of the disciplinary literature on the subject and through the detailed description of some recent experimental tools. In particular, by questioning how to operationalize the integration of local assessment methods and global indicators through a GeoBIM platform, the paper raises broader questions on the relationship between measurement, policies and planning practices. In particular, the revision of priority criteria according to the 2030 Agenda goals is read in the text as a useful opportunity to rethink a number of administrative tools and practices. Indeed, the development of a GeoBIM platform to support building permit applications could not only make the assessment of compliance with local regulations more efficient and automated but also allow for the measurement of project impacts against indicators aimed at the local declination of the sustainability goals defined by the 2030 Agenda.

Testing variations of methodological characteristics on the 5-0-5 test: impact of the linear sprint on change-of-direction deficit of adult male soccer players
Authors: Clemente Filipe Manuel , Garrett Joel M. , González-Fernández Francisco Tomás , Filipa Silva Ana , Nobari Hadi
Published: May 2023

Purpose

The study compared the change-of-direction deficit (CODD) using the first 10-m sprint of a 40-m sprint test (CODDoriginal), the 10-m time that precedes the 5-0-5 test (CODD5-0-5start), and the best 10-m split of a 40-m sprint test (CODDbest).

Methods

A cross-sectional study design was applied. Twenty elite male soccer players (age: 21.6 ± 2.0 years; experience: 8.7 ± 2.3 years; body mass: 73.2 ± 6.1 kg; stature: 174.8 ± 4.5 cm) voluntarily participated in this study. They were assessed in the following tests: (i) 40-m linear sprint test and (ii) 5-0-5 test with a pre-planned 180° change-of-direction (COD) (left and right sides). CODD for both sides was calculated as the difference between average 5-0-5 and CODDoriginal, COODbest, and CODD5-0-5start.

Results

The time over 10 m during the 30–40-m split of a 40-m sprint test was significantly shorter than the first 10 m of the same sprint test (best times: p < 0.001, d = –7.077; average time: p < 0.001, d = –1.140) and the first 10-m acceleration phase of the 5-0-5 test (best times: p < 0.001, d = 9.000; average times: p < 0.001, d = –8.500). No significant differences were found between the first 10 m of the 40-m sprint test and the 5-0-5 test (best times: p > 0.999, d = 0.133; average times: p = 0.990, d = 0.047). Comparisons of CODD revealed significant differences between approaches (best times: F = 201.7, p < 0.001, ηp2 = 0.914; average times: F = 196.2, p < 0.001, ηp2 = 0.912). However, there were no significant correlations between any CODD outcomes and the 40-m sprint test (p > 0.05).

Conclusions

CODD calculated with the first 10 m and the best 10 m of a sprint test was significantly different; similarities existed between the initial 10 m of a 40-m sprint test and the 5-0-5 test. Therefore, to save time and resources, practitioners could use the first 10-m acceleration phase of the 5-0-5 since no significant differences were found between the initial 10 m of a linear sprint test.

Retorno a la oscuridad. Tres conferencias sobre la filosofía del arte contemporáneo
Authors:   Facultad de Artes y Humanidades Uniandes, Rapko John , Cruz Tupac
Published: May 2023

En Retorno a la oscuridad se presentan tres conferencias en las que John Rapko reflexiona sobre el papel del arte contemporáneo y su relación con la sociedad actual. Basado en la idea de Philip Fisher de que el arte moderno es una reacción a la claridad óptica del impresionismo, en este libro se plantea que es necesario mantener la tradición de misterio para evitar que continúe siendo un arte del inconformismo, burocratizado y cooptado institucionalmente. En estas páginas, Rapko propone la idea de un arte posconceptual que combine la idea con la encarnación y la práctica, y que así las obras tengan la capacidad de rivalizar con la falsa claridad de la omnipresencia de la contaminación mediática.

Incidencia de la sostenibilidad en la gestión educativa, la situación latinoamericana
Authors: Medina Alvarado Iván Leonardo
Published: May 2023

Ser sostenible se ha convertido en una de las metas más destacadas no solo por los empresarios y los gobiernos, sino que se ha evidenciado que ha cobrado un rol determinante al interior de los sistemas educativos, llevando la premisa de prologar con el paso del tiempo propuestas educativas que atiendan a las necesidades de los diferentes grupos poblacionales; ahora bien, esta prolongación en el tiempo requiere que se cuente con la pertinencia necesaria para atender oportunamente las necesidades y particularidades de la sociedad, ya que no se buscan imponer modelos educativos o propuestas educacionales, todo lo contrario, se orientan a una constante articulación entre las necesidades y las propuestas para atender dichas necesidades, donde es claro comprender que la participación social es la clave del éxito. Así las cosas, se abordan tres ejes centrales que permiten comprender como incide la sostenibilidad la gestión educativa, y como quienes hacen de la educación un proceso de dignificación del ser humano, deben comprender que no solo es en una dirección tal proceso educativo, sino que es un proceso bidireccional y multidireccional, de allí que se abordan los siguientes tres ejes:  a) La sostenibilidad en el gobierno educativo, b) Relacionamiento con los stakeholders, y c) Valor compartido en la educación; pareciese que esta concepción de la sostenibilidad es distante de la realidad educativa, salvo que en el siguiente documento se analiza tal integración a partir de la mirada latinoamericana.
Simulating organic aerosol in Delhi with WRF-Chem using the volatility-basis-set approach: exploring model uncertainty with a Gaussian process emulator

Abstract. The nature and origin of organic aerosol in the
atmosphere remain unclear. The gas–particle partitioning of semi-volatile
organic compounds (SVOCs) that constitute primary organic aerosols (POAs) and
the multigenerational chemical aging of SVOCs are particularly poorly
understood. The volatility basis set (VBS) approach, implemented in air
quality models such as WRF-Chem (Weather Research and Forecasting model with Chemistry), can be a useful tool to describe emissions
of POA and its chemical evolution. However, the evaluation of model
uncertainty and the optimal model parameterization may be expensive to probe
using only WRF-Chem simulations. Gaussian process emulators, trained on
simulations from relatively few WRF-Chem simulations, are capable of
reproducing model results and estimating the sources of model uncertainty
within a defined range of model parameters. In this study, a WRF-Chem VBS
parameterization is proposed; we then generate a perturbed parameter
ensemble of 111 model runs, perturbing 10 parameters of the WRF-Chem model
relating to organic aerosol emissions and the VBS oxidation reactions. This
allowed us to cover the model's uncertainty space and to compare outputs from
each run to aerosol mass spectrometer observations of organic aerosol
concentrations and O:C ratios measured in New Delhi, India. The simulations
spanned the organic aerosol concentrations measured with the aerosol mass spectrometer (AMS). However,
they also highlighted potential structural errors in the model that may be
related to unsuitable diurnal cycles in the emissions and/or failure to
adequately represent the dynamics of the planetary boundary layer. While the
structural errors prevented us from clearly identifying an optimized VBS
approach in WRF-Chem, we were able to apply the emulator in the following two periods: the
full period (1–29 May) and a subperiod period of 14:00–16:00 h LT (local
time) on 1–29 May. The combination of emulator analysis and model
evaluation metrics allowed us to identify plausible parameter combinations
for the analyzed periods. We demonstrate that the methodology presented in
this study can be used to determine the model uncertainty and to identify the
appropriate parameter combination for the VBS approach and hence to provide
valuable information to improve our understanding of OA production.
Sensitivity analysis of a Martian atmospheric column model with data from Mars Science Laboratory

Published: May 2023

Abstract. An extensive sensitivity analysis was performed for a horizontally homogeneous and hydrostatic 1-D column model at the Mars Science Laboratory (MSL) location. Model experiments were compared with observations from the Curiosity Rover Environmental Monitoring Station humidity (REMS-H) device. Based on our earlier column model investigations, model surface temperature and pressure, dust optical depth (τ) and column precipitable water content (PWC) were the initial parameters that we investigated by our sensitivity analysis. Our analysis suggests that the most sensitive initial parameters for the column model temperature profile are τ and the surface temperature. The initial value of PWC does not affect the temperature profile of the model, but it is the most important parameter for the humidity profile. The initial value of τ also seems to have some effect on the humidity profile of the model. Based on our analysis, variations in surface pressure initialization are negligible for the model’s humidity and temperature predictions. The model simulations are generally in good agreement with the observations. Our analysis suggest that a slightly different shape of the model’s initial humidity profile could yield better results in the predicted water vapor volume mixing ratios at 1.6 m.
VIRTUAL REALITY TRAVERSE: A NOVEL WAY TO TEACH TRAVERSE SURVEYING
Authors: Lau L. , Mack A. , Yao W.
Published: May 2023

Abstract. With the advancement of technology, lowered cost in hardware and widely available development tools, more and more educators across different disciplines have used virtual reality as a mean to enhance their teaching. The hit of the pandemic has also speeded up the adoption of virtual reality in education where face-to-face classes and practicals are suspended/cancelled. Virtual Reality as a tool to facilitate teaching and learning has created a new way for learners to experience the materials instead of receiving information passively through books and videos. Traverse survey is one of the main topics in surveying, it is a method used for control survey through establishing a series of points that are linked together by straight lines to form a framework. Traversing involves setting a total station and prism targets at points along the traverse line to do observations. Measurements of angles and distances are taken for the calculation of the points’ coordinates using trigonometry. This paper illustrates using freely available tools to develop a virtual reality program for doing traverse survey, the program is used in an assignment as a virtual fieldwork tool for students to learn traverse surveying at home and anywhere with a computer.
MEASURE UP: A SERIOUS GAME FOR TOPOGRAPHIC EDUCATION
Authors: Vermandere J. , Bassier M. , Vergauwen M.
Published: May 2023

Abstract. Topographic education requires the use of delicate and expensive equipment in a wide range of field exercises. To reduce the risk of improper handling by students, this work proposes the creation of a serious game to teach the basic principles and correct techniques to complete the field exercises successfully. Due to the constant evolution of the course material, there is also a need for a modular and expandable design to increase the relevance of the serious game over a longer period. Using a system of cloud-based hosting and progression, we can make sure the students are always using the most up-to-date version of the game. The game covers a wide variety of topics, ranging from levelling to triangulation. It is currently in use at the KU Leuven Geomatics group and has been evaluated positively by the bachelor students.
Probing environmental and tectonic changes underneath Mexico City with the urban seismic field

Published: May 2023

Abstract. The sediments underneath Mexico City have unique mechanical properties that give rise to strong site effects. We investigated temporal changes in the seismic velocity at strong-motion and broadband seismic stations throughout Mexico City, including sites with different geologic characteristics ranging from city center locations situated on lacustrine clay to hillside locations on volcanic bedrock.
We used autocorrelations of urban seismic noise, enhanced by waveform clustering, to extract subtle seismic velocity changes by coda wave interferometry. We observed and modeled seasonal, co- and post-seismic changes, as well as a long-term linear trend in seismic velocity.
Seasonal variations can be explained by self-consistent models of thermoelastic and poroelastic changes in the subsurface shear wave velocity. Overall, sites on lacustrine clay-rich sediments appear to be more sensitive to seasonal surface temperature changes, whereas sites on alluvial and volcaniclastic sediments and on bedrock are sensitive to precipitation. The 2017 Mw 7.1 Puebla and 2020 Mw 7.4 Oaxaca earthquakes both caused a clear drop in seismic velocity, followed by a time-logarithmic recovery that may still be ongoing for the 2017 event at several sites or that may remain incomplete. The slope of the linear trend in seismic velocity is correlated with the downward vertical displacement of the ground measured by interferometric synthetic aperture radar, suggesting a causative relationship and supporting earlier studies on changes in the resonance frequency of sites in the Mexico City basin due to groundwater extraction.
Our findings show how sensitively shallow seismic velocity and, in consequence, site effects react to environmental, tectonic and anthropogenic processes. They also demonstrate that urban strong-motion stations provide useful data for coda wave monitoring given sufficiently high-amplitude urban seismic noise.
Representation of soil hydrology in permafrost regions may explain large part of inter-model spread in simulated Arctic and subarctic climate

Published: May 2023

Abstract. The current generation of Earth system models exhibits large inter-model differences in the simulated climate of the Arctic and subarctic zone, with differences in model structure and parametrizations being one of the main sources of uncertainty. One particularly challenging aspect in modelling is the representation of terrestrial processes in permafrost-affected regions, which are often governed by spatial heterogeneity far below the resolution of the models' land surface components. Here, we use the Max Planck Institute (MPI) Earth System Model to investigate how different plausible assumptions for the representation of permafrost hydrology modulate land–atmosphere interactions and how the resulting feedbacks affect not only the regional and global climate, but also our ability to predict whether the high latitudes will become wetter or drier in a warmer future. Focusing on two idealized setups that induce comparatively “wet” or “dry” conditions in regions that are presently affected by permafrost, we find that the parameter settings determine the direction of the 21st-century trend in the simulated soil water content and result in substantial differences in the land–atmosphere exchange of energy and moisture. The latter leads to differences in the simulated cloud cover during spring and summer and thus in the planetary energy uptake. The respective effects are so pronounced that uncertainties in the representation of the Arctic hydrological cycle can help to explain a large fraction of the inter-model spread in regional surface temperatures and precipitation. Furthermore, they affect a range of components of the Earth system as far to the south as the tropics. With both setups being similarly plausible, our findings highlight the need for more observational constraints on the permafrost hydrology to reduce the inter-model spread in Arctic climate projections.
Analysis of Motion Characteristics and Metabolic Power in Elite Male Handball Players
Authors: Bassek Manuel , Raabe Dominik , Memmert Daniel , Rein Robert
Published: May 2023

While handball is characterized by repeated sprints and changes of direction, traditional player load models do not consider accelerations and decelerations. The aim of this study was to analyze the differences between metabolic power and speed zones for player load assessment with regard to the player role. Position data from 330 male individuals during 77 games from the 2019/20 German Men’s Handball-Bundesliga (HBL) were analyzed, resulting in 2233 individual observations. Players were categorized into wings, backs and pivots. Distance covered in different speed zones, metabolic power, metabolic work, equivalent distance (metabolic work divided by energy cost of running), time spend running, energy spend running, and time over 10 and 20 W were calculated. A 2-by-3 mixed ANOVA was calculated to investigate differences and interactions between groups and player load models. Results showed that total distance was longest in wings (3568 ± 1459 m in 42 ± 17 min), followed by backs (2462 ± 1145 m in 29 ± 14 min), and pivots (2445 ± 1052 m in 30 ± 13 min). Equivalent distance was greatest in wings (4072.50 ± 1644.83 m), followed by backs (2765.23 ± 1252.44 m), and pivots (2697.98 ± 1153.16 m). Distance covered and equivalent distance showed moderate to large interaction effects between wings and backs (p < .01, ES = 0.73) and between wings and pivots (p < .01, ES = 0.86) and a small interaction effect between backs and pivots (p < .01, ES = 0.22). The results underline the need for individualized management of training loads and the potential of using information about locomotive accelerations and decelerations to obtain more precise descriptions of player load during handball game performance at the highest level of competition. Future studies should investigate the influence of physical performance on smaller match sequences, like ball possession phases.
Transfer Ranking in Finance: Applications to Cross-Sectional Momentum with Data Scarcity
Authors: Poh Daniel , Roberts Stephen , Zohren Stefan
Published: May 2023

Modern cross-sectional strategies incorporating sophisticated neural architectures outperform their traditional counterparts when applied to mature assets with long histories. However, deploying them on instruments with limited samples generally produces over-fitted models with degraded performance. In this paper, we introduce Fused Encoder Networks -- a hybrid parameter-sharing transfer ranking model which fuses information extracted using an encoder-attention module from a source dataset with a similar but separate module operating on a smaller target dataset of interest. This mitigates the issue of models with poor generalisability. Additionally, the self-attention mechanism enables interactions among instruments to be accounted for, both at the loss-level during model training and at inference time. Focusing on momentum applied to the top ten cryptocurrencies by market capitalisation as a demonstrative use-case, our model outperforms state-of-the-art benchmarks on most measures and significantly boosts the Sharpe ratio. It continues outperforming baselines even after accounting for the high transaction costs associated with trading cryptocurrencies.
Incorporating Alternative Risk Premia into Balanced Portfolios: Is there any added value?
Authors: Naya Francesc , Tuchschmid Nils S. , Rrustemi Jahja
Published: May 2023

Evaluating Alternative Risk Premia products as standalone investments is not sufficient to conclude whether these products add value to institutional investors, whose portfolios are largely composed of well-diversified equity and bond allocations, and usually smaller ones to alternative assets. We study whether the inclusion of ARP products adds value to two well-known benchmarks of balanced allocations: the 60/40 world equity/bond portfolio and the Pictet LPP 2015-60 index. Taking a sample of live ARP products from 2016 to May 2021, we find that a systematic allocation to ARP with no equity exposure improves risk-adjusted performance, due to risk reduction, even though it causes a small drag in long-term return. This impact is similar to the one many investors seek in Trend-Following funds or Tail-Hedge products, for which we compare results. The drag in performance disappears if one can dynamically manage the inclusion of ARP into the balanced portfolios, even though market timing ability is at the very least a rare asset.

Published: May 2023

The focus of this article is on the correlation between board diversity, financial performance, and risk. In particular, the study examines the presence of female and foreign directors on corporate boards. The research uses a sample of 15 Vietnamese listed banks during 2014-2020. The findings indicate that the number of female directors on boards does not have a significant relationship with bank performance or risk. Additionally, the study reveals a negative relationship between the presence of foreign directors and bank risk.
IMPACT OF FOREIGN DIRECT INVESTMENT ON ECONOMIC GROWTH: A TIME SERIES ANALYSIS OF PAKISTAN
Authors:   Department of Economics, University of Sargodha, Pakistan, Awan Aqsa , Waqas Muhammad ,   Department of Economics, University of Sargodha, Pakistan
Published: May 2023

The study aims to determine the relationship between foreign direct investment and economic growth in the case of Pakistan by using the annual data from 1973-2021. The three independent variables are foreign direct investment, inflation, and trade while gross domestic product (GDP) is the dependent variable. The unit root test results explore that all variables are integrated at first difference. The Johansen cointegration technique examines both short- and long-term relationships. The study found log run as well as short run relationship among variables. All variables are integrated at first difference, based on the outcomes of the first unit root test. The Johansen cointegration method is used to investigate both the short-term and long-term connections. The findings suggest that while inflation negatively correlates with GDP, trade and foreign direct investment have a favorable (positive) effect on economic expansion. The policy recommendation is that only some foreign investment sectors benefit Pakistan's economy due to the different characteristics of developing and developed countries. The Government may give incentives to foreign investors, give cheap raw materials, and make better economic policies that are fruitful for foreign investors. The Government may reduce the taxes directly and indirectly and give subsidies. Keywords: Economic Growth, Inflation, Trade, FDI

El estudio se realizó empleando una base de datos de 115 registros de las respuestas de los asistentes a dicho evento, en el cual se medía además de los datos demográficos como sexo, edad, datos sobre las exposiciones, el servicio, la calidad de la alimentación, hospedaje, alabanzas, y la evaluación general del evento. Para obtener la confiabilidad del instrumento se empleó el Coeficiente Alfa de Cronbach dado que el tipo de pregunta de escala ordinal en escala Likert así lo permitía. Se realizó un análisis factorial exploratorio en donde se determinaron ocho factores que representan con claridad las dimensiones de la evaluación, obteniendo así una nueva propuesta de un instrumento con propiedades de validez y confiabilidad aceptables para sus propósitos.

Authors: Coa Clemente Ramiro
Published: May 2023

El objetivo principal de este estudio es determinar cuál es el modelo más apropiado para analizar datos de sobrevivencia infantil en Bolivia. Además del modelo semiparamétrico de riesgos proporcionales de Cox, se evalúan tres modelos paramétricos: exponencial, Weibull y gamma generalizado. Para abordar el objetivo se comparan tres resultados: los coeficientes estimados a partir de los distintos modelos, la significancia de las covariables en términos del valor-p y el criterio de información de Akaike (AIC). Se concluye que el modelo Weibull es más apropiado que el modelo de Cox para analizar datos de sobrevivencia infantil en Bolivia, si bien ambos modelos conducen a resultados parecidos. También se recomienda contrastar siempre los resultados de los modelos paramétricos con los del modelo de Cox

La gestión de las empresas del sector de la Economía Popular y Solidaria tiene una importancia vital para la generación de impactos en la población y sus territorios. El presente trabajo tiene como objetivo brindar una panorámica acerca de la importancia de la implementación de herramientas de marketing en las empresas la Economía Popular y Solidaria para un mejor aprovechamiento del modelo de gestión solidario. Para el desarrollo de esta investigación, se adoptó fundamentalmente un enfoque cualitativo y descriptivo, para brindar una amplia perspectiva sobre la temática escogida, mediante la revisión bibliográfica y el análisis de documentos oficiales de la Superintendencia de Economía Popular y Solidaria del Ecuador. Entre los principales hallazgos se determinó que las empresas del sector de la economía solidaria no explotan al máximo aún su esencia como modelo económico alternativo, a pesar de que el Estado ecuatoriano les ha otorgado mayor visibilidad, todavía no se les incentiva ni comprende lo suficientemente, entre las principales barreras se encuentran: las dificultades de acceso a los mercados, a medios y recursos productivos, la descoordinación entre el orden jurídico y la acción de las instituciones. El futuro de este sector depende del fortalecimiento institucional y su gestión, para lo cual las estrategias de marketing son clave en este proceso.

This study investigated the physical and mechanical properties of cement-stabilized compressed blocks manufactured with coal bottom ash sourced from a power plant in Niger. Three different grain sizes were used for the production of compressed blocks with a hand-operated press. Thermal, hydric, mechanical, and fire resistance properties were assessed on the samples. It was found that the use of finer bottom ash resulted in lighter blocks with a density of about 1.02 mg/m3 and thermal conductivity in the range of 0.27 – 0.41 W/m·K. The size of the bottom ash used for the production of blocks did not significantly affect the value of mechanical strength. The exposure of blocks to temperatures of 200°C and 400°C did not reduce the strength of the samples. Neat bottom ash blocks can offer better thermal properties than typical building materials and provide acceptable mechanical strength.
POWER-DISTANCE & POLITICAL APATHY: SURVEY OF FACULTY MEMBERS IN HIGHER EDUCATION INSTITUTION

Published: May 2023

The culture in Hofstede's work offered a lens through which to view cross-cultural disparities. The model proposes the concept of 'power distance (PD)' as means of understanding the gap between authority and power between governors/leaders and the governed/followers. 'Political apathy' (PA) and alienation are common among citizens who experience high power distance (High-PD). Citizens are more likely to get involved in politics, vote, and take action when there is less of a gap between them and those in the power. The purpose of this research was to quantify the quality of these connection from the perspective of academics at Thal University Bhakkar, Punjab Pakistan. The results of study provide significant information about the existence of the potential relationships between variables which thus help in reaching the desired conclusion. The positive and negative associations between PD and PA and PP are supported by field research. It will be crucial for stakeholders to adapt their strategies and practices in light of the recommendations made in the field study.

Introducción: Desde el año 2015, la Declaración del consenso de la Asociación Americana del Corazón 2 Varios estudios previos han demostrado que existe evidencia donde muestra que hay algún nivel de desconocimiento en el personal de salud sobre la RCP. Un estudio realizado en la India entre médicos y enfermeros internos mostró que el 36% de los internos de enfermería y el 46% de los internos de medicina tenían conocimientos deficientes y el 42% de los internos de medicina y el 52% de los internos de enfermería tenían deficiencia a la hora de poner en prácticas la RCP. 4 Materiales y métodos: Se utilizó para la recolección de datos una plataforma en línea la cual fue ofrecida a que cualquier profesional en salud pudiese completarla, por lo que la selección de los formulario se dio al azar. El formulario contenía 15 preguntas sobre datos de conocimiento del profesional, como la profesión y tiempo de graduado, así como conceptos básicos de reanimación cardiopulmonar descritos en el consenso de  la Asociación Americana del Corazón del año 2014.  Para la tabulación de los datos se utilizó Excel y Jamovi ® para el análisis estadístico. Se utilizó la prueba de Shapiro – Wilk para determinar si existe normalidad en los datos. Resultados: El 36.1 % de los participantes no tienen los cursos de soporte cardiaco al día y el 16.4 % no ha realizado reanimación cardiopulmonar (RCP) en ámbito real. Resultados:  Al revisar las respuestas sobre la profundidad solo el 37.7 % contestó de manera adecuada siendo el grupo de estudiantes de TEM el que tuvo mayor porcentaje de personas que contestaron de manera adecuada con un 67 %, seguido de los TEM con 47 %, médicos un 35 %, enfermería 20 % y los APA y auxiliares con 0 %. Para la profundidad de las compresiones según el grupo si tienen al día o no los cursos, el grupo que no los tiene al día tuvo una media de respuestas correctas de 13.6 % (DE 35.1%) y los que si tienen los cursos al día 51.3 % (DE 50.6 %) con un valor de T de -3.09 y un p valor 0.003. Para la profundidad de las compresiones según el grupo si tienen al día o no los cursos, el grupo que no los tiene al día tuvo una media de respuestas correctas de 13.6 % (DE 35.1%) y los que si tienen los cursos al día 51.3 % (DE 50.6 %) con un valor de T de -3.09 y un p valor 0.003. Conclusiones: Luego del análisis es posible determinar con la población participante que existen deficiencias en el conocimiento de aspectos básicos como la frecuencia y profundidad de las compresiones torácicas. Adicionalmente aspectos como causas específicas de actividad eléctrica sin pulso como las fases de la parada cardiaca muestran porcentajes bajos de respuestas correctas, adicionalmente existe diferencia entre tener al día los grupos de tener o no al día los cursos de RCP.
