La ciudad turística y sus contradicciones: una reflexión a partir del ejemplo de Playa del Carmen
Authors: Marie dit Chirot Clément
Published: April 2024

El presente artículo analiza los conflictos por la apropiación del espacio a lo largo del desarrollo de la ciudad turística de Playadel Carmen, en el estado mexicano de Quintana Roo. En un contexto caracterizado por un crecimiento demográfico acelerado y por un intenso fenómeno de especulación inmobiliaria, estos conflictos ponen en evidencia la importancia de las contradicciones sociales vinculadas con la tenencia del suelo, así como el papel central que dichas contradicciones desem­peñan en la dinámica urbana. En particular, el artículo muestra las consecuencias de tal fenómeno desde el punto de vista del acceso a la vivienda de los grupos sociales más vulnerables e insiste en la resistencia de estos grupos, reflejada por la creación de la importante colonia popular Luis Donaldo Colosio. A partir del ejemplo de Playadel Carmen, y basándose en el trabajo teórico de Henri Lefebvre, el artículo tambien cuestiona la manera en que el fenómeno de urbanización turística contribuye a agudizar lo que el filósofo marxista llamó las “contradicciones del espacio”, las cuales cobran especial intensidad en el contexto de la ciudad neoliberal.
¿Vino viejo en odres nuevos? Las misiones del sureste en la reorganización franciscana de México, 1940-1995
Authors: Rodríguez Alejandro
Published: April 2024

El artículo reconstruye críticamente el proceso del retorno de la Orden de Frailes Menores (OFM) al sureste de México durante la segunda mitad del siglo XX. Unavez suprimida la provincia colonial de San José de los Naturales en el siglo XIX, los frailes menores se ausentaron de la región para no regresar sino hasta la década de 1940, como parte de una nueva oleada misionera, resultado de un largo proceso de reordenamiento social y territorial del catolicismo en México, así como de cambios doctrinales y organizacionales del ser y quehacer de los franciscanos. El texto analiza datos documentales e inicia la reflexión con la llegada de los primeros misioneros franciscanos a Yucatán, provenientes de la provincia del Santo Evangelio, y concluye con la fundación en 1995 de una nueva entidad en el sureste: la provincia San Felipe de Jesús.
Narcotraficantes extranjeros en el narcopolicial sudamericano: el caso de El enviado de Medellín (1993) y de Bioy (2012)
Authors: Libuy Pulgar Paula Macarena
Published: April 2024

La novela El enviado de Medellín (1993), del periodista chileno Ignacio González Camus y la novela Bioy (2012), del escritor peruano Diego Trelles Paz, aunque se distancian en términos cronotópicos, se encuentran a medio camino entre el relato policial y el de la narconovela al cumplir y desafiar los elementos asociados a estos subgéneros propuestos por Leonardo Padura y otros autores, por el lado policial actual, y Danilo Santos, Ingrid Urgelles y Ainhoa Vásquez, por el lado narcoliterario, entre otras voces. Lo interesante es que, al mismo tiempo que se muestra al colombiano Geoffrey Davenport y al mexicano Natalio Correa como personajes narcotraficantes y extranjeros, también se exponen las redes nacionales que facilitan sus negocios y que remiten a una historia que precede a la llegada de estos migrantes, lo que descentra el imaginario xenofóbico que se ha difundido desde discursos oficiales. De esta manera, el análisis de estas dos novelas sudamericanas ofrecerá sus propias versiones sobre la problemática en términos locales y continentales, las cuales permiten abrir horizontes hacia perspectivas transversales que van más allá de las legalistas. Son obras representativas de un sólido corpus chileno y peruano que se sigue expandiendo y que refracta los entramados sistémicos que han acompañado desde siempre al negocio de las drogas ilegales en los terrenos de la realidad.

Monitoring and Controlling of Greenhouse
Authors: C Prof. Veena
Published: April 2024

Abstract: The potential for revolutionizing crop production practices has drawn significant attention to the monitoring and management of greenhouse settings. With the help of greenhouses, plants may grow in a controlled environment with the right amount of light, heat, humidity, and soil moisture. However, manual monitoring and intervention—which may be timeconsuming, laLbor-intensive, and prone to human error are frequently used in traditional greenhouse management techniques. The design, implementation, and assessment of a greenhouse monitoring and controlling system built around the ESP32 controller are proposed in this research paper. In order to gather environmental data—such as temperature, humidity, soil moisture, and light intensity—that is essential for determining plant health and maximizing growth conditions, the system incorporates sensors. Farmers may remotely get real-time insights into their greenhouse operations by transmitting the acquired data to a cloud platform or central monitoring station using the ESP32's networking features. the incorporation of ESP32 controllers into greenhouse management is a noteworthy technical development that has the potential to completely transform current agricultural methods. ESP32-based systems give farmers a strong tool for maximizing agricultural productivity while reducing resource inputs and environmental effects by providing real-time monitoring and precise control of environmental conditions

Authors: Sham Fatimah , Huda Sulaiman Nurul , Seman Asiah , Akma Shohor Norhafizatul , Yao Mun Choo
Published: April 2024

Central line-associated bloodstream infections (CLABSI) are mainly preventable with evidence-based guidelines. However, it needs to be made clear how well these guidelines are followed in critical care units in Malaysia. Therefore, this study evaluates critical care nurses’ knowledge, practices, and attitude toward evidence-based guidelines for preventing CLABSIs issued by the Centers for Disease Control and Prevention and the Malaysia Ministry of Health. This study aims to identify the level of knowledge, practice, and attitudes regarding preventing CLABSI among critical care nurses in a teaching hospital. A cross-sectional descriptive study was carried out among 203 nurses working in seven units consisting of the Intensive Care Unit (ICU), Coronary Care Unit (CCU), Intermediate Dependency care Unit (IDCU), Neonatal Intensive Care Unit (NICU), Neurosurgery Intensive Care Unit (Neuro ICU), Cardiac Intensive Care Unit (CICU), and Pediatric Intensive Care Unit (PICU) in University Malaya Medical Center in Kuala Lumpur. Nurses completed online questionnaires regarding their demographic characteristics, knowledge, practices, and attitudes toward evidence-based guidelines for preventing CLABSIs from December 2022 to January 2023. The data was analyzed using T-Test, ANOVA, and Fisher’s Exact Test. 203 ICU nurses completed the questionnaire, and none correctly answered all the knowledge-related questions. The response rate of the correct answer regarding the knowledge question was only 49.7%. Mean scores for 11 questions regarding knowledge of evidence-based guidelines for preventing CLABSI were low, 5.85 (± 1.29). Meanwhile, individual total scores were significantly associated with time spent as a nurse in the ICU (2–4 years). The mean score for eight questions related to CLABSI prevention was 4.19 (± 0.50), which was acceptable for the compliance score. There was an association between nurses’ gender (p-value: 0.01) and their duration of working experiences in the ICU (p-value: 0.04) with the practice regarding the prevention of CLABSI. The overall mean score for nurses’ attitudes toward the guidelines was high; 8.63 (± 1.37). However, there was no association between the demographic characteristic and attitude regarding preventing CLABSI. The knowledge and practice of ICU nurses need to be improved. Regular training with the implementation of available guidelines and protocols was essential to improve the knowledge and compliance on preventing CLABSIs in ICUs.

Published: April 2024

Insects can be found in a wide range of habitats, including deep jungles, agricultural plantations and even in our own homes and gardens. There are, however, harmful insects that have been classified as medically important, such as mosquitoes and flies. The goal of this study is to design, develop and validate a questionnaire for measuring primary schoolchildren’s knowledge, attitude and practices (KAP) about medically important insects in Malaysia. A mixed method study was employed, and the questionnaire was designed in Phase 1 by reviewing several literature studies. Twenty questionnaire items were face-validated by 24 recognised experts in medical entomology during Phase 2. The construct validity and reliability of the questionnaire were assessed using the exploratory factor analysis (EFA), principal components analysis (PCA) and Cronbach’s alpha (α). As a result, the questionnaire’s final collection has 16 items in each of their respective domains. With Cronbach’s alpha of 0.7, the consistency was found to be acceptable. The developed questionnaire can be used to assess schoolchildren’s KAP towards medically important insects, hence increasing the possibility of reaching two Sustainable Development Goals (SDGs), good health and well-being (SDG 3) and quality education (SDG 4).

Authors: Ruslan Aida Awanis , Mahadi Siti Nurliyana , Sh Abdullah Sharifah Shafinaz , Ernastin Tobi Hermiana
Published: April 2024

The outbreak of the novel coronavirus (COVID-19) pandemic has rapidly spread across the globe, causing huge disruptions to everyday lifestyles, including in Malaysia. The government-enforced movement control order (MCO) forced the closure of all public and private educational institutions, affecting all the physical learning sessions as they must be shifted to online and distance learning (ODL). This has created stress among lecturers due to these unanticipated changes. A total of 12 participants were involved in this qualitative phenomenology design to explore their experiences of the ODL and how they cope with their stress. Face-to-face interviews were carried out with the guidance of a semi-structured interview format. Thematic analysis of the in-depth interview transcriptions found there were 6 themes, and 15 subthemes representing feelings, challenges, and ways of dealing with ODL. The study concluded that ODL during the COVID-19 pandemic can affect mental health and well-being among participants.
A study into the image of the accountant: How undergraduate students perceive the accounting profession and what influences this perception
Authors: Georgiou Melissa , Cameron Robyn , Schleimer Stephanie
Published: April 2024

While accounting matters more than ever in our modern society, the image of the accountant remains less understood. This study explores perceptions of the image of the accountant of university students in first, second and third-year courses across both accounting and non-accounting majors. Despite ranking among Australia’s growing professions, undergraduate enrolments and new entrants to professional associations are falling. Disruptive change necessitates a shift from the stereotypical “bean-counter” image to that of a strategic advisor. This study examines how distance from the profession and source of influence affect undergraduate students’ perceptions of the image of the accountant. Our findings reveal that a group’s distance from the accounting profession does affect perceptions of the attractiveness of the image of the accountant and the further the group is away from the profession, the less attractive the image. Further, this study finds that different sources of influence create different images where the influence of teachers creates a more attractive image than when media is included as a source of influence. Our findings have implications for educators and professional associations.

Authors: Tefera Orthodox , Otieno Jared Okello
Published: April 2024

With increasing technological advancement in contemporary society, various systems have been developed to improve public fund management. Several public entities have adopted the well-liked integrated financial management information system (IFMIS) for managing their finances. The current study aimed to identify factors influencing the implementation of the IFMIS. This case study on the County Government of Migori involved 255 employees. Principal component analysis (PCA) was used to identify the most significant factors that influence the implementation of IFMIS. The factors were categorized into technological, organisational, environmental, cultural, and ethical. From the analysis, training and dependency on experts were significant technological factors. For the organizational factors, the three key influencers were observed to be creating an organizational culture that dictates how the county operates, developing an organizational culture that supports technology and use in various departments, and having the ability to use it in record management, such as classification and storage. For environmental factors, the most crucial influencer was the efficiency of IFMIS systems. On cultural and ethical factors, this study revealed that importance is the ability to distinguish motivation from corruption, support openness and accountability in implementation, and put in place a formal organizational evaluation of culture. By understanding the importance of these factors, policymakers and administrators in the Migori County Government can prioritize resources and efforts towards addressing these key areas.

Published: April 2024

Studies conducted in recent years have demonstrated the positive effects
of sacubitril/valsartan and dapagliflozin on cardiac prognosis and
performance. These drugs can potentially be abused as doping agents by
professional athletes. In our study, we evaluated the effects of
sacubitril/valsartan and dapagliflozin on athletic performance. In the
study, the swimming performances of three groups of rats were evaluated
by dividing them into control, sacubitril/valsartan and dapagliflozin
groups. Additionally, echocardiography, weight and rotarod data were
evaluated during follow-up. In the comparison of sacubitril/valsartan
and control groups, a statistical difference was seen in the 13th, 19th
and 20th swimming sessions, and when the total and average swimming
times were compared, the p values were 0.115 and 0.015. In the
comparison of dapagliflozin and control groups, a statistical difference
was observed starting from the 10th swimming session, and when the total
and average swimming times were compared, the p values were
<0.001 and <0.001. In triple analysis, a statistical
difference was seen from the 9th swimming session until the end of the
experiment. Furthermore, a statistical difference was observed in
rotarod results for sacubitril/valsartan and dapagliflozin compared to
baseline. (p value <0.001 and 0.011 respectively) Our study
showed a limited positive effect of sacubitril/valsartan on athletic
performance. The impact of dapagliflozin on athletic performance was
shown to be particularly significant.
Multi-UAV Energy Consumption Minimization using Deep Reinforcement Learning: An Age of Information Approach
Authors: Kim Jeena , Park Seunghyun , Park Hyunhee
Published: April 2024

This letter introduces an innovative approach for minimizing energy
consumption in multi-UAV (Unmanned Aerial Vehicles) networks using Deep
Reinforcement Learning (DRL), with a focus on optimizing the Age of
Information (AoI) in disaster environments. We propose a hierarchical
UAV deployment strategy that facilitates cooperative trajectory
planning, ensuring timely data collection and transmission while
minimizing energy consumption. By formulating the inter-UAV network path
planning problem as a Markov Decision Process (MDP), we apply a Deep
Q-Network (DQN) strategy to enable real-time decision-making that
accounts for dynamic environmental changes, obstacles, and UAV battery
constraints. Our extensive simulation results, conducted in both rural
and urban scenarios, demonstrate the effectiveness of employing a memory
access approach within the DQN framework, significantly reducing energy
consumption up to 33.25\% in rural settings and
74.20\% in urban environments compared to non-memory
approaches. By integrating AoI considerations with energy-efficient UAV
control, this work offers a robust solution for maintaining fresh data
in critical applications, such as disaster response, where ground-based
communication infrastructures are compromised. The use of replay memory
approach, particularly the online history approach, proves crucial in
adapting to changing conditions and optimizing UAV operations for both
data freshness and energy consumption.
Potter Cove’s Heavyweights: Estimation of species’ interaction strength of an Antarctic food web
Authors: Rodriguez Iara , Saravia Leonardo
Published: April 2024

Understanding the complex interplay between structure and stability of
marine food webs is crucial for assessing ecosystem resilience,
particularly in the context of ongoing environmental changes. In the
West Antarctic Peninsula, global warming has led to severe alterations
in community composition, species distribution, and abundance over the
last decades. In this study, we estimate the interaction strength within
the Potter Cove (South Shetland Islands, Antarctica) food web to
elucidate the roles of species in its structure and functioning. We use
these estimates to calculate food web stability in response to
perturbations, conducting sequential extinctions to quantify the
importance of individual species based on changes in stability and food
web fragmentation. We explore connections between interaction strength
and key topological properties of the food web. Our findings reveal an
asymmetric distribution of interaction strengths, with a prevalence of
weak interactions and a few strong ones. Species exerting greater
influence within the food web displayed higher degree and trophic
similarity but occupied lower trophic levels and displayed lower
omnivory levels (e.g., macroalgae and detritus). Extinction simulations
revealed the key role of certain species, particularly amphipods and the
black rockcod Notothenia coriiceps, as their removal led to significant
changes in food web stability and network fragmentation. This study
highlights the importance of considering species interaction strengths
in assessing the stability of polar marine ecosystems. These insights
have crucial implications for guiding monitoring and conservation
strategies aimed at preserving the integrity of Antarctic marine
ecosystems.
Land Reclamation Controls on Multi-Centennial Estuarine Evolution
Authors: Schrijvershof Reinier , Maren Dirk Sebastiaan van , Wegen Mick van der , Hoitink A.J.F. (Ton)
Published: April 2024

Land reclamations influence the morphodynamic evolution of estuaries and
tidal basins, because altered planform changes tidal dynamics and
associated residual sediment transport. The morphodynamic response time
to land reclamation is long, impacting the system for decades to
centuries. Other human interventions (e.g., deepening of fairways or
port construction) add a morphodynamic adaptation timescale to a system
that may still adapt as the result of land reclamations. Our
understanding of the cumulative effects of anthropogenic interference
with estuaries is limited, because observations usually do not cover the
complete morphological adaptation period. We aim to assess the impact of
land reclamation works and other human interventions on an estuarine
system by means of digital reconstructions of historical morphologies of
the Ems Estuary over the past 500 years. Our analysis demonstrates that
the intertidal-subtidal area ratio altered due to land reclamation works
and that the ratio partly restored after land reclamation ended. The
land reclamation works have led to the degeneration of an ebb- and flood
channel system, transitioning the estuary from a multichannel to a
single-channel system. We infer that the 20th-century intensification of
channel dredging and re-alignment works accelerated rather than cause
this development. The centennial-scale observations suggest that
estuarine systems responding to land reclamations follow the
evolutionary trajectory predicted by tidal asymmetry-based stability
theory as they move towards a new equilibrium configuration with
modified tidal flats and channels. Existing estuarine equilibrium
theory, however, fails in linking multichannel stability to the loss of
intertidal area, emphasizing the need for additional research.
Explaining geographic, social, and economic differences as drivers of internal migrations in Viet Nam: Empirical findings from push and pull forces analysis
Authors: Huy Huynh , Nonneman Walter , Son Nguyen
Published: April 2024

Viet Nam has deeply experienced internal migration during its development
history, typically movements from rural to urban and across regions since
the launch of economic reform policy in 1986. This article adopts the
cost-minimization approach to calculate the push and pull forces of the
internal migrations across geographic distances of provinces and then
explains those forces along with socio-economic factors within 63 provinces
and cities in Viet Nam based on the census data during the period 2010-2019.
The empirical findings from the solution to cost-migration equations between
the number of migrants and the inverse distance across 63 provinces reported
that the push and pull forces are quite heteroskedastic, mostly due to
differences in geographic, social, and economic development. Not
surprisingly, the Mekong River Delta (MRD) is still the most repulsive
region for migrants, accounting for 30% of the total number migrants of the
country and notable 98% of migrants who moved to the Southeastern (SE)
region as the most attractive destination. It is obviously proven that the
push and pull forces of migrations in a province correlate strongly and
significantly with economic factors including relative incomes and poverty
rate rather than human factors such as urbanization, population, and labor
forces. Finally, discussions about policy implications of equitable
investments across regions in Viet Nam are really necessary and could be a
potential for creating job opportunities and improving standards of
livelihoods.
Development of a Framework of Key Internal Control and Governance Principles for Robotic Process Automation (RPA)
Authors: Eulerich Marc , Waddoups Nathan , Wagener Martin , Wood David A.
Published: April 2024

Although robotic process automation (RPA) usage is growing rapidly in accounting, concerns are emerging regarding the internal controls and overall governance structure surrounding RPA. To help address these concerns, we use a design science research approach and work with a Fortune 500 company to develop an RPA governance framework. The framework consists of four governance areas and 14 control requirements, which help maximize the benefits and minimize the risks associated with the use of RPA. We validate that the framework is useful and generalizable to many organizations by presenting the framework to and subsequently interviewing and surveying 86 professionals at different organizations, including internal and external auditors, chief audit executives at several multinational corporations, academics, accounting and finance professionals, and other RPA stakeholders. Their feedback suggests the framework is successful in achieving its objectives.

We aimed to clarify the relationship between intra- and periorgan fats, visceral fat, and subcutaneous fat. We used abdominal computed tomography to evaluate intra- and periorgan fat accumulations in the pancreas, liver, spleen, renal parenchyma, renal sinus, and skeletal muscle. The relationships between these fats, visceral fat, and subcutaneous fat were examined by using partial correlation and covariance analysis, adjusting for BMI. We found that visceral fat and all intra- and periorgan fat accumulations were positively correlated, whereas subcutaneous fat and accumulations of all intra- and periorgan fats and visceral fat were negatively correlated. Individuals with excessive visceral fat accumulation had significantly greater accumulations of fat in the pancreas, liver, renal sinus, and skeletal muscle than those without excessive visceral fat accumulation (P = 0.01, 0.006, 0.008, and 0.02, respectively). In conclusion, all intra- and periorgan fat accumulations show a positive correlation with visceral fat and a negative correlation with subcutaneous fat, independent of BMI.

Statistical literacy (hereafter SL) has been considered an important learning outcome in statistics learning in higher education, yet studies that focus on investigating the factors and conditions that influence students’ SL, especially mathematics education students, are still limited. This study seeks to uncover the factors and conditions that significantly contribute to the SL of mathematics education students. This survey study involved 1,287 mathematics education students from 21 higher education institutions in Indonesia. Linear regression analysis involving four predictor variables (i.e., gender, status of higher education institution, laptop ownership, and research preference) was performed to determine the variables that contributed significantly in predicting SL achievement. The results revealed that gender, higher education institution’s status, and laptop ownership contributed significantly, but research preference was not significant in predicting mathematics education students’ SL. Furthermore, laptop ownership was found to have the highest contribution in predicting mathematics education students’ SL. All findings and their implications are discussed.

Published: April 2024

The teaching method of virtual co-teaching helps the mutual sharing of new experiences and methods of pedagogues in teaching in formal education, through digital technologies. It also facilitates the involvement of practitioners in teaching, which can be a key mechanism for ensuring quality education. This article focused on comparing the effectiveness of co-teaching in two environments, face-to-face and virtual. In terms of methodology, an experiment was used, which was implemented in three independently selected schools, from which eight groups of thirty students were formed. The phenomenon measured was the level of understanding of the material taught during these lessons of history, mathematics and a foreign language. The test results of the individual groups were subsequently analyzed. From the results, we can confirm the null hypothesis based on the independent samples t-test and the Mann-Whitney U test, which indicates that there is no statistically significant difference between the test results of the two groups. However, it is essential to emphasize the added value in virtual co-teaching, which is primarily in the economic aspect and flexibility. Specifically, it is a reduction in the cost of commuting, reduced time and easy availability of experts. These results form the basis for follow-up research that can focus on improving the quality of teaching using this method.

Published: April 2024

This article delves into the influence of population aging on the modernization of agriculture and rural territories in China. It highlights the profound demographic challenge faced by modern China, characterized by wide-spread population aging. The issue is particularly acute in rural areas, where rapid urbanization and industriali-zation have depleted the working-age population significantly. Concurrently, agriculture remains a vital sector of China’s economy, necessitating urgent modernization efforts. However, this process is fraught with uncer-tainty due to the complex demographic landscape. The article provides an overview of the current rural situa-tion, offers the author’s insights into the root causes of the crisis, and formulates a series of recommendations for its resolution. In conclusion, addressing the impact of population aging on agricultural modernization and rural development in China’s provinces requires a multifaceted approach. It is crucial to recognize the unique challenges faced by rural areas, such as the depletion of the working-age population and the need for agricul-tural modernization. Implementing targeted policies and programs that encourage innovation, improve rural infrastructure, and provide support for aging populations can help mitigate these challenges. Additionally, fos-tering collaboration between government agencies, research institutions, and local communities is essential for developing sustainable solutions. By addressing these issues, China can overcome the challenges posed by population aging and ensure the continued growth and development of its rural areas.

Kegiatan ini dipilih karena baik dalam budaya Sunda dan Tionghoa terdapat kemiripan pandangan tentang bulan. Kemiripan pandangan inilah yang mendasari kegiatan PPM melalui kolaborasi dengan berbagai komunitas Sunda dan Tionghoa. Festival Bulan dilaksanakan dengan menggandeng Yayasan Dana Sosial Priangan (YDSP) Bandung yang telah memiliki aset yang diperlukan untuk terlaksananya kegiatan ini. PPM dilaksanakan melalui empat tahap, yaitu tahap discover, design, define, dan reflect.

Pada kegiatan ini baik masyarakat etnis Sunda dan etnis Tionghoa saling mengenal dan belajar tentang bulan dari budaya yang berbeda sehingga tujuan pelaksanaan kegiatan ini untuk memperkuat interaksi antara budaya Sunda dan Tionghoa tercapai. Besides the Sundanese ethnic group as the largest ethnic group in the city of Bandung, there is also the Chinese ethnic group. To strengthen tolerance and enhance mutual understanding and appreciation between these two ethnic groups, a Community Service Activity (PPM) was conducted in the form of a Moon Festival with the theme "Bright Moonlight Brings Happiness". This activity was chosen because both Sundanese and Chinese cultures have similarities in their views of the moon. It is this similar perspective that underpins the PPM activity through collaboration with various Sundanese and Chinese communities. The Moon Festival was carried out in collaboration with Yayasan Dana Sosial Priangan (YDSP) Bandung, which already has the necessary assets for the implementation of this activity. PPM was carried out through four stages: discover, design, define, and reflect.
