Authors: Sadriwala Maruf Fatima , Sadriwala Kaneez Fatima
Published: January 2022

Marketers may have several objectives including the increase in market share, profitability, sustainability, green behavior and above all innovation. Many observers believe that for innovation, Artificial Intelligence (AI) and Machine Learning (ML) capabilities play a vital role in developing general-purpose technologies which impact the economy and society at large. The present study examines the influence of perceived usefulness and Ease of use of artificial intelligence on marketing innovation. The base model underlying this research is Technology acceptance Model (Davis, 1989). Partial Least Squares (PLS) has been used to establish the relationship among variables. A cross-sectional empirical evidence has been collected. The results indicate that there is a significant positive relationship between perceived usefulness of artificial intelligence and marketing innovation. Therefore, we recommend marketers and producers to give due attention to overall marketing innovation and artificial intelligence generated information for sustainability.
ICT Adoption Implications for SME Innovation and Augmentation
Authors: Baporikar Neeta
Published: January 2022

The adoption of information communication technology (ICT) by small and medium enterprises (SMEs) plays a critical role in their development, growth, and expansion. To achieve a competitive advantage, an enterprise needs to have the resources and capabilities to operate efficiently. The fast improvement of ICT is rapidly shifting the conventional way of performance in all facets of SMEs. Today, all kinds of establishments are accepting the implementation and usage of ICT to advance administrative efficiency, outputs, and improved communication for strengthening their competitiveness. SMEs need to opt speedily for the adoption of ICT to support their strategy, performance, and development. Adopting a mixed research approach, with an exploratory sequential mixed design, the study focus is on the factors influencing ICT acceptance and adoption implications for SME augmentation. Findings reveal that SMEs face challenges in ICT adoption due to a lack of resources. Hence, there is a need for investing in advanced technology to augment SME innovation and growth through ICT adoption.

Published: January 2022

Data is becoming a powerful tool for both businesses and governments. Data can be public, open, government, and even linked. In several countries, including the United States, England, and France, open data has made it possible to open digitized public data explicitly to the general public. These data help strengthen relations between governments, businesses and citizens through greater transparency and the possibility of using them in several areas, including digital governance. The purpose of this work is to study open data influence on digital governance across four dimensions applied to some case studies related to several activity sectors, all to enhance its use.

Authors: Carden Lila Lenora , Brace Carol
Published: January 2022

A Project Management Office (PMO) is one entity that can be used to deliver products and services to internal and external customers by using projects and project management tools and techniques. This study aims to provide an account of how to use a project to make recommendations about how to implement a Project Management Office (PMO). A case study example is used to demonstrate how an IT international company used the OPM3 (Organizational Project Management Maturity Model) approach to: (a) acquire knowledge; (b) perform assessment; and (c) managing improvements. The authors include a discussion about specific PMO implementation steps as compared to the challenges from previous implementations and thoughts about how the PMO after implementation provides value to the organization as well as value to the project human resources. Finally, the authors conclude the paper with thoughts related to the contributions of this study and the associated limitations and applicability to other implementations.

Blended Learning
Authors: Megahed Naglaa , Ghoneim Ehab
Published: January 2022

As we approach a new normal in post-COVID-19 pedagogy, we need to consider blended learning (BL) as a significant contribution to precautionary and preventive actions for containing the spread of COVID-19. This paper provides a framework to recognize transformation to a new normal by 1) reviewing the history of BL associated with its models and design options; 2) presenting general characteristics of BL in a matrix of place, distance, and technology; and 3) analyzing scenario planning and strategies for reopening academic institutions. Based on the BL continuum and health and safety conditions resulting from the pandemic, the study first proposed a scenario planning framework. Second, it developed a classification framework of BL addressing its continuum, models, and learning theories via a smart learning environment. Finally, the study proposed a conceptual matrix of BL that considers health and safety conditions resulting from the COVID-19 pandemic.
Analysis of Production Line Project Based on Value Sensitive Design
Authors: Kong Lu , Li Jihua
Published: January 2022

Value sensitive design is a new method to embed moral value into the design process and possesses broad research prospects. However, there is a gap between the industrial application and the practical application of VSD since its practical application focuses on human-computer interaction and medical ethics. In this paper, the conceptual, empirical, and technical investigation of VSD are analyzed, and the feasibility of VSD for production line design is demonstrated. It was applied to the production line design process in Shenyang, Liaoning Province, China. Then, specific design issues such as environmental sustainability and safety are solved by analyzing the value demands of stakeholders and balancing the value tension. Thus, the human value of the production line becomes more sensitive, and the value conflict between natural and technical artifact is alleviated. In this process, we reflect on the design problems to be solved and obtain valuable opinions, enabling VSD to better adapt to the industrial production line design.

Published: January 2022

With the rising numbers of COVID – 19 patients, universities are moving toward virtual teaching platforms. It is acceptable for lectures and discussions. But conducting ward classes in virtual platforms is practically difficult. We initiated hybrid ZOOM ward classes with a simple method of using mobile phones at the University Surgical Unit of the Colombo South Teaching Hospital. Feasibility and the student's perception of the effectiveness of such teaching were evaluated. Clinical teaching using hybrid ZOOM is feasible. Mobile phones provide satisfactory audio and video experience. The majority of the students are satisfied with the hybrid ZOOM ward classes.
Protection of Quiescence and Longevity of IgG Memory B Cells by Mitochondrial Autophagy
Authors: Kodali Srikanth , Li Min , Budai Marietta M , Chen Min , Wang Jin
Published: January 2022

The development of long-lived immune memory cells against pathogens is critical for the success of vaccines to establish protection against future infections. However, the mechanisms governing the long-term survival of immune memory cells remain to be elucidated. In this article, we show that the maintenance mitochondrial homeostasis by autophagy is critical for restricting metabolic functions to protect IgG memory B cell survival. Knockout of mitochondrial autophagy genes, Nix and Bnip3, leads to mitochondrial accumulation and increases in oxidative phosphorylation and fatty acid synthesis, resulting in the loss of IgG+ memory B cells in mice. Inhibiting fatty acid synthesis or silencing necroptosis gene Ripk3 rescued Nix−/−Bnip3−/− IgG memory B cells, indicating that mitochondrial autophagy is important for limiting metabolic functions to prevent cell death. Our results suggest a critical role for mitochondrial autophagy in the maintenance of immunological memory by protecting the metabolic quiescence and longevity of memory B cells.

Psychosocial benefits of the social support experienced at a community-based cancer wellness organization
Authors: Meluch Andrea
Published: January 2022

This study was designed to identify the sources of social support and the perceived psychosocial benefits people diagnosed with cancer experience at a community-based cancer wellness organization. Semi-structured, in-depth interviews were conducted with 31 people diagnosed with cancer who regularly used services at a community-based cancer wellness organization. Two themes were identified related to the sources of social support that participants experienced at the community-based cancer wellness organization: i) participants reported that individuals at the center (e.g., staff and volunteers) provided support, and ii) participants perceived the organization as a source of support. Further, four themes emerged related to participants’ perceptions of the psychosocial benefits of social support experienced at the community-based cancer wellness organization including i) reduced feelings of social isolation; ii) acceptance at the center in contrast to stigmatizing experiences elsewhere; iii) validation of new identity; and iv) experiences of relaxation and stress relief. The study findings demonstrate that community-based cancer wellness organizations can be a source of connection, acceptance, validation, and stress relief to people diagnosed with cancer.
Pods, Squads, and Crash Nights
Authors: Malone Erin D , Hayden Kris R
Published: January 2022

We developed an alumni mentoring system to help support veterinary students during the coronavirus disease 2019 (COVID-19) pandemic. The goal was to connect students to the outside world and provide support to students who were in increasingly isolated circumstances. Students were separated into “pods” for in-person laboratories, and each pod was assigned to two-to-three mentors. This model did not work well and was exchanged for more targeted efforts. Small group mentoring was provided to those students who requested it, and the remaining alumni were recruited to offer evening conversations to anyone interested. This combination seemed to better meet the needs of students and alumni and provided an avenue to access alumni support from across the country. More structure, enhanced mentor support, and attendance requirements may better meet our mentoring goals for a larger group of students.
Validated scales for substance use disorders in the geriatric population
Authors: Sarkar Siddharth , Sood Esha , Bhad Roshan , Mishra Ashwani
Published: January 2022

Substance use disorders in the elderly population can be assessed through scales and questionnaires. These scales are used for not only screening for substance use disorders but also for assessment for improvement with time and/or intervention. Validity parameters of these scales help us know how do they perform during application in the clinical or community setting. The objective of the review was to (1) review available validated screening tools for substance use disorders, (2) summarize elderly-focused studies, and (3) provide recommendations for use in clinical care. We aimed to review the validated scales of substance use disorders in the geriatric population. We looked at PubMed and Web of Science databases for identifying English language peer-reviewed publications that reported at least one validity parameter for scale in geriatric patients with substance use disorders. We identified 22 studies, with majority of them focusing on alcohol use disorder. Alcohol Use Disorder Identification Test and Cut Down, Annoyed, Guilty, and Eye-Opener Questionnaire (CAGE) were the most common scales used in the population. While most of the studies reported acceptable area under receiver operator curve, sensitivity, and specificity, some of the studies reported lower sensitivity/specificity at optimal cutoff. Validity parameters of various scales have been assessed in the geriatric population. Using suitable cutoffs, they can be useful in the screening of elderly individuals with substance-related problems, so that due evaluation and care can be provided. More instruments need to be assessed for validity to diagnose tobacco use disorders, benzodiazepine use disorders, and other substance use disorders.
Asymptotic growth of Mordell–Weil ranks of elliptic curves in noncommutative towers
Authors: Ray Anwesh
Published: January 2022

Let E be an elliptic curve defined over a number field F with good ordinary reduction at all primes above p, and let
$F_\infty $
be a finitely ramified uniform pro-p extension of F containing the cyclotomic
$\mathbb {Z}_p$
-extension
$F_{\operatorname {cyc}}$
. Set
$F^{(n)}$
be the nth layer of the tower, and
$F^{(n)}_{\operatorname {cyc}}$
the cyclotomic
$\mathbb {Z}_p$
-extension of
$F^{(n)}$
. We study the growth of the rank of
$E(F^{(n)})$
by analyzing the growth of the
$\lambda $
-invariant of the Selmer group over
$F^{(n)}_{ \operatorname {cyc}}$
as
$n\rightarrow \infty $
. This method has its origins in work of A. Cuoco, who studied
$\mathbb {Z}_p^2$
-extensions. Refined estimates for growth are proved that are close to conjectured estimates. The results are illustrated in special cases.
Torsion properties of modified diagonal classes on triple products of modular curves
Authors: Lilienfeldt David T.-B. G.
Published: January 2022

Consider three normalized cuspidal eigenforms of weight
$2$
and prime level p. Under the assumption that the global root number of the associated triple product L-function is
$+1$
, we prove that the complex Abel–Jacobi image of the modified diagonal cycle of Gross–Kudla–Schoen on the triple product of the modular curve
$X_0(p)$
is torsion in the corresponding Hecke isotypic component of the Griffiths intermediate Jacobian. The same result holds with the complex Abel–Jacobi map replaced by its étale counterpart. As an application, we deduce torsion properties of Chow–Heegner points associated with modified diagonal cycles on elliptic curves of prime conductor with split multiplicative reduction. The approach also works in the case of composite square-free level.
Classification of eCRS: Based on disease outcome or normal range?: Comment on Toro et al.
Authors: Pan L. , Liu Z.
Published: January 2022

Undoubtedly, there is a lack of unanimous histopathologic criteria to classify eosinophilic chronic rhinosinusitis (eCRS) worldwide. We read with great interest the recent constructive systematic review by Toro et al.(1). The authors stretched out the current knowledge on the methods of classifying eCRS to determine an optimal cut-off point. While the authors are to be congratulated for their comprehensive overview, a point regarding the disease recurrence as the most relevant parameter to divide eosinophilic and noneosinophilic inflammation in chronic rhinosinusitis (CRS) should be discussed. In order to contribute to an evidence-based standardization of cut-off point to classify eCRS, we would like to share our considerations and approaches in this comment.

Published: January 2022

Malaria is one of the most serious health problems in many countries, including Iran. Accurate diagnosis is important regardless of the elimination status of a country. A cross-sectional study was performed on 105 people who were suspected to be positive for malaria infection in Sistan and Baluchistan, Iran. Blood smears (thin and thick films) were stained with 10% Giemsa. DNA was extracted from the prepared thin and thick films for molecular methods. Multiplex/nested polymerase chain reaction (mn-PCR), loop-mediated isothermal amplification (LAMP), and light microscopy (LM) were compared with nested PCR (nPCR) as a gold standard. Of 105 subjects, 52 (49.5%), 58 (55.2%), 58 (55.2%), and 63 (60%) were positive for malaria by LM, nPCR, mn-PCR, and LAMP, respectively. The sensitivity, specificity, and kappa were 92.1%, 100%, and 0.9 for LAMP and 100%, 100%, and 1 for mn-PCR, respectively. Eight cases of coinfection (Plasmodium vivax and Plasmodium falciparum) that were not detected by LM method were diagnosed by mn-PCR and LAMP. In the present study, the high sensitivity and specificity of LAMP and mn-PCR indicate that these two tests are good alternatives to nPCR for malaria diagnosis

Authors: P. T. Quoc L.
Published: January 2022

ABSTRACT. Essential oil (EO) was extracted from Melaleuca cajuputi Powell leaves using the steam distillation method. The main aim of this study is to determine several physicochemical properties of EO, including acid value, saponification value, ester value, relative density, absolute density, and freezing point. In addition, the chemical components were also analyzed using the gas chromatography–mass spectrometry (GC–MS) method. The obtained 1,8-cineol content is quite high (71.83%). In addition, these components in EO had an antioxidant capacity and antibacterial activity, including gram-positive and gram-negative bacteria (using the paper disc diffusion method for antibiotic susceptibility testing). Particularly, this EO inhibited the growth of Escherichia coli (ATCC 25922), Salmonella enteritidis (ATCC 13076), and Staphylococcus aureus (ATCC 25923).

Spectral characterization and biological studies of some ternary complexes with molecular docking investigations against MERS and SARS type coronaviruses
Authors: P. Saikishore V. , K. Biswal S. , K. Mohapatra R.
Published: January 2022

ABSTRACT. A series of ternary complexes with a Schiff base (HL1) derived from 2-hydrazinobenzimidazole and o-hydroxybenzophenone (primary ligand) have been prepared. Here, 1,10-phenanthroline acts as secondary ligand (L2). These metal complexes were investigated by UV-Vis, IR, 1H NMR and thermal techniques. The spectral data confirmed tridentate nature of the SB ligand with NNO type coordination, whereas the secondary ligand L2 (1,10-phenanthroline) coordinated through its two nitrogen atoms (NN type). These compounds possess distorted octahedral geometry. Moreover, these compounds were screened against B. subtilis and E. coli to evaluate their antibacterial activity. In addition, molecular docking studies were performed against MERS-CoV and SARS-CoV-2 main protease (Mpro). Moreover, DFT calculations and QSAR studies of the SB ligand were also performed.

Published: January 2022

ABSTRACT. A new series of hybrid 2-quinolinone derivatives were synthesized by using 7-hydroxy-4-methyl-1-amino-quinolin-2-one (2) and cinnamic acid. Hybrid halogenated 2-quinolinone derivatives (3-(7-hydroxy-4-methyl-3,6,8-tribromo-2-oxo-2H-quinolin-1-ylamino)-3-phenyl acrylic acid (4) and 3-(7-acetoxy-4-methyl-3,6,8-tribromo-2-oxo-1H-quinolin-1-ylamino)-3-phenyl acrylic acid (7)) were prepared via the halogenation of 3-(7-hydroxy-4-methyl-2-oxo-2H-quinolin-1-ylamino)-3-phenyl acrylic acid (3) with bromine to give compound 4 with acetic anhydride led to the formation of hydride halogenated 2-quinolinone derivative (7). All the synthesized hybrid 2-quinolinone and hybrid halogenated 2-quinolinone derivatives were tested for their cytotoxicity against MCF-7 cell line. DNA flow cytometric analysis of compounds 3 showed cell cycle arrest at G2/M phase with concomitant increase of cells in apoptotic phase. Dual annexin-V/propidium iodide staining assay of compound 3 revealed that, the selected molecule increases the apoptosis of MCF-7 cells more than control.

Authors: M. Samir E. , M. Mohareb R.
Published: January 2022

ABSTRACT. The multi-component reaction of ethyl acetoacetate with each of malononitrile (3) benzaldehyde (1) in ethanol containing triethylamine gave the ethyl 6-amino-5-cyano-2-methyl-4-phenyl-4H-pyran-3-carboxylate (4). The latter compound reacted with hydrazine hydrate to give the hydrazide derivative 6. Compound 6 underwent a series of hetero-cyclization reactions to give pyrzole, hydraide-hydrazone, thiazole derivatives. The produced compounds tested against cancer cell lines six cancer cell lines and showed that compounds 8b, 10b, 11a, 17a, 21 and 24a were the most cytotoxic compounds. Further tests of the latter compounds toward the five tyrosine kinases and Pim-1 kinase showed that compounds 10b, 21 and 24a were the most potent of the tested compounds and compounds 10a, 11a and 17a were of the highest inhibitions toward Pim-1 kinase. The high inhibitions of most of the tested compounds toward the selected cancer cell lines and the tyrosine kinases encourage for future work to be done.

comunes-indígenas ante la globalización. Tramas para entender las luchas por la descolonización
Authors: Martinez de Bringas Asier
Published: January 2022

El objetivo de este trabajo era dar medida del carácter expropiante y destructivo que el colonialismo ha tenido y tiene sobre la realidad de los pueblos indígenas, y cómo el colonialismo continúa proyectando globalmente sus sombras de destrucción en tiempos de aniquilación ecológica. Consideramos los comunes-indígenas como el núcleo desde donde entender el planteamiento de transformación y resistencia comunitaria de los pueblos indígenas; el lugar que otorga fundamento y sentido a su práctica política de derechos. Hemos transitado hacia una crítica política del concepto Derechos de la Naturaleza, en un sentido doble: como crítica de lo que no es, de su tergiversación por parte del Estado; como propuesta alternativa para comprender la centralidad que la ecología de vivientes tiene en las cosmovisiones indígenas. Finalmente, concluimos con lo que consideramos las principales fracturas en la protección de los derechos indígenas, brechas que reposan, en última instancia, en la necesidad de anular y destruir la comprensión indígena de la(s) vida(s) por el potencial crítico que implican para la nueva razón colonial.
neocons españoles: sus ideas y su influencia en la política exterior de José María Aznar

Este articulo tiene como objetivo explicar el hecho político  de los neoconservadores españoles  que  siguiendo a  los neocons estadounidenses  importaron sus doctrinas sobre política exterior en especial la teoría de la Hegemonía Benevolente que justifica en virtud  del poder norteamericano  y de sus ideales democráticos: la subordinación de los Estados Occidentales  frente a los Estados Unidos. En el artículo se hace  consideraciones genéricas  sobre el fenómeno neocon en España. Se estudian los principales escritos de los neocons españoles más reconocidos  y su influencia en la opinión pública  y el artículo termina negando  la opinión de reputados profesores como Celestino del Arenal, José Antonio Sanahuja y Manuel Iglesias Cavicchioli que mantiene que fueron los neocons españoles  los responsables del giro de la política exterior de José María Aznar en su segunda legislatura entre  los años 2002 y 2004.
Giovanni Sabadino degli Arienti: un intelectual boloñés entre humanismo cortesano y «querelle des femmes»
Authors: Rodríguez Mesa Francisco Jose
Published: January 2022

Giovanni Sabadino degli Arienti (Bolonia, aprox. 1445 – 29 de mayo de 1510) fue uno de los principales exponentes de las letras boloñesas del último tercio del Quattrocento. Una de sus épocas más prolíficas como escritor tuvo lugar entre la segunda mitad de la década de 1480 y los primeros años del decenio siguiente. En este arco cronológico, la producción del autor comienza a hacerse eco de la denominada «querelle des femmes» y Sabadino empieza a preocuparse por distintos aspectos de la vida de las mujeres, que se convierten en el centro de tres de sus obras: el Trattato della pudicizia (1487), la Gynevera de le clare donne (1489-1490) y el Elogio di Isabella (aprox. 1493). En este trabajo analizamos estos tres títulos para rastrear el modo en que se gestan y se configuran las preocupaciones filóginas del autor.
Cristina Trivulzio di Belgioioso, la princesa italiana socialista y feminista
Authors: González de Sande Estela
Published: January 2022

La princesa Cristina Trivulzio di Belgioioso es una de las figuras más relevantes del Risorgimento italiano en el plano político, social y cultural. Entre su legado figuran tratados filosóficos, ensayos político-históricos, textos literarios y numerosas contribuciones en periódicos franceses e italianos. Se trata, pues, de una mujer filósofa, historiadora, política, periodista y literata, cuya pluma se convirtió en pleno siglo XIX en arma contra las injusticias sociales, contra los gobiernos absolutistas o contra las desigualdades entre hombres y mujeres. Su enorme erudición y determinación le granjearon el respeto y la admiración de prohombres y mujeres ilustres de la época, siendo ejemplo y modelo de un nuevo ideal de mujer, afín a la sociedad moderna y progresista a la que aspirará Italia tras la unidad nacional.
Este estudio presenta un sucinto recorrido por su trayectoria vital y su compromiso político y social, así como un análisis de su aportación a la querella de las mujeres, con el objetivo de exponer el pensamiento político de la autora y sus ideales socialistas y feministas.
Derechos humanos, globalización y los procesos de lucha y resistencia de las mujeres indígenas en América Latina
Authors: Cruz Zúñiga Pilar Guadalupe
Published: January 2022

El artículo visibiliza cómo las resistencias y las luchas de las mujeres indígenas en América Latina suponen procesos de construcción de derechos humanos al enfrentar varias lógicas de dominación: el capitalismo neoliberal y la dominación colonial y el patriarcado que lo sustentan. Utilizando la teoría crítica de derechos humanos, se enfoca menos el plano normativo-institucional y jurídico-positivo que predomina en la concepción hegemónica de derechos humanos, y se pone más la atención en la sociedad civil como fundamento de derechos humanos, por lo que las movilizaciones sociales reivindicativas son uno de los componentes importantes en el proceso de constituir derechos.
Repensando las teorías de las Relaciones internacionales a colación del fracaso de EEUU en Afganistán. Una mirada materialista ecléctica
Authors: Molina Campano Eduardo Manuel
Published: January 2022

El interés de esta investigación radica en repensar las teorías de las Relaciones Internacionales a colación del fracaso de EEUU en Afganistán. No se trata de un análisis exhaustivo del conflicto en sí, sino de un intento por comprender el conflicto desde las teorías (neo)liberales, (neo)realistas y críticas. Mi conclusión es doble, por un lado propongo y defiendo que, –al igual que el (neo)liberalismo y el (neo)rrealismo se basan a fin de cuentas en una suerte de eclecticismo epistemológico y ontológico a la hora de planificar las acciones en política internacional–, las teorías críticas emancipatorias deberían apostar por un eclecticismo crítico materialista –más allá de las excepciones idealistas– con el objeto de superar el fraccionalismo teórico-práxico de los movimientos sociales y de los Estados subalternos; Por otro lado afirmo que el fracaso de EEUU en Afganistán y el advenimiento Talibán, fue debido, entre otras cosas –inseguridad permanente, corrupción generalizada y malas prácticas de las tropas ocupantes–, al desconocimiento de la subjetividad cultural de la población afgana que gira en torno al islam y a sus preceptos irracionalistas.

Published: January 2022

This paper assesses the risk of land subsidence related to the underground Karst caves at the section Km55+660- Km55+690 of North-South Vietnam Expressway by finite element method using PLAXIS 2D V.8.5 software. The research results show that there is a risk of collapsing the ceiling of the underground Karst caves due to the impact of the embankment process and the vehicle load. The research results also show that the vertical displacement is larger than the allowable residual settlement according to Vietnamese standard; it is necessary to take the soft soil improvement to achieve the allowable residual settlement. Several construction solutions are proposed to prevent the risk of land subsidence in the research section. In particular, flyover through the section with underground Karst caves is the most suitable solution.
Integrating Geological Information and Electrical Resistivity Tomography for Mapping the Main Groundwater Bearing Layers in Ancient Babylon City, Iraq

Published: January 2022

Electrical resistivity tomography was conducted in nine locations within ancient Babylon city, using Wenner-Schlumberger array, to map groundwater-bearing layers. The inverted models were integrated and correlated with the geological information extracted from six boreholes drilled during the 1970s. The interpreted inverse models of the Wenner-Schlumberger show identical corresponding with the lithological sequence of the boreholes. This corresponds related to the presence of one thick layer of sand deposits, with a thickness that may reach 60 m, and several thin interbedded clay layers that are locally extended. The sand layer is considered the main groundwater-bearing layer in the area. Further, the results proposed that a high discharge rate from any future boreholes which will be drilled for lowering the groundwater levels in the ancient Babylon area can easily cause a washing out of sand deposits which in turn can cause serious damages in archaeological remaining even after all measures to prevent sand washing.
Spinal epidural hematoma in an infant patient: a differential diagnostic of spinal cord compression syndrome
Authors: Pineda Felipe Gutierrez , Marin Mauro Marcelo Suarez , Cadavid Daniela Perez
Published: January 2022

A spontaneous spinal epidural hematoma is a collection of blood in the epidural space of the spine occurring in the absence of trauma or other pathological  blood conditions, this epidural blood clot has the risk to compress the spinal cord and impact negatively on the neurological outcome of the patients.
With a low incidence on pediatrics this condition has not been studied deep, with difficulties on the clinical approach in infants and children due to the limitation in the pediatric neurological exam with the risk to be misdiagnosed. We describe a rare case of spinal cord compression on a young 14 month old patient with a spontaneous cervicothoracic epidural hematoma that presented with a ascending paralysis. Magnetic resonance imaging of the spine demonstrated an extensive epidural hematoma between C4 to T5 with spinal cord compression. An emergency laminectomy was performed with evacuation of the epidural blood clot with a total improve of the neurologic symptoms and without any residual hematoma following 3 months of the surgery.
The spontaneous spinal epidural heamtoma is rare cause of spinal cord compression on infants and children with high risk of neurological impact without prompt diagnosis with MRI and emergent surgical evacuation.
Modelo de plan financiero para microempresas comerciales establecidas en Ciudad Juárez
Authors: Gallardo Hernández Norma Alicia , Carmona Vega Esther Guadalupe
Published: January 2022

En México existe una gran cantidad de microempresas que tienen particular importancia para las economías nacionales por las aportaciones a la producción y distribución de bienes y servicios. De acuerdo con Esparza, Pérez y Campos (2017) en su estudio encontraron que en promedio solamente 2 de cada 10 microempresas mexicanas llevan una administración contable, económica y financiera, lo cual representa un porcentaje demasiado bajo, y esto es una de las más fuertes desventajas de las microempresas. De manera que, este trabajo presenta una recopilación de los elementos idóneos que debe contener un plan financiero para microempresas comerciales, con el propósito de ayudar en la correcta toma de decisiones a los propietarios y/o gerentes de MiPymes establecidas en Ciudad Juárez, Chihuahua.
Abstract 
In Mexico there is a large number of microenterprises that are particularly important for national economies because of the contributions to the production and distribution of goods and services. According to Esparza, Pérez and Campos (2017) in their study they found that on average only 2 out of 10 Mexican microenterprises have an accounting, economic and financial administration, which represents a percentage that is too low, and this is one of the strongest Disadvantages of microenterprises. So, this work presents a compilation of the ideal elements that a financial plan for commercial microenterprises must contain, with the purpose of helping in the correct decision making to the owners and / or managers of MiPymes established in Ciudad Juárez, Chihuahua.
Modelo exponencial no lineal del producto interno bruto de México
Authors: Zepeda Mercado Gabriela , Salgado Vega Jesús
Published: January 2022

Con el procedimiento de modelación Autorregresivo no lineal con Transición Suave (STAR, por sus siglas en inglés), se estima el comportamiento no lineal del ciclo económico de México, como resultado de la asimetría entre sus fases. Se considera a la serie correspondiente a la tasa de crecimiento trimestral del Producto Interno Bruto de México 1980.1-2014.1, como ciclo específico para el análisis. Se concluye que la estimación de un modelo no lineal STAR de tipo exponencial, provee de una capacidad explicativa y de predicción superior de los datos, en comparación con un modelo Autorregresivo lineal (AR, por sus siglas en inglés).
Abstract 
Using the Smooth Transition Nonlinear Autoregressive (STAR) modeling procedure, we estimate the nonlinear behavior of Mexico's business cycle, as a result of the asymmetry between its phases. The series corresponding to the quarterly growth rate of Mexico's Gross Domestic Product 1980.1-2014.1 is considered as the specific cycle for the analysis. It is concluded that the estimation of a non-linear exponential STAR model provides a superior explanatory and predictive capacity of the data, compared to a linear Autoregressive (AR) model.

Published: January 2022

El trabajo está relacionado con la posición que adoptan las Micro, Pequeñas y Medianas Empresas (MIPyMES) frente al reto de la Responsabilidad Social Empresarial (RSE). El objetivo es identificar si estas empresas están familiarizadas con la RSE, si desarrollan sus actividades productivas en apego a los principios de esta filosofía, si se realizan de manera intencionada, si se persigue un objetivo específico, y por último, conocer si están interesadas en obtener el reconocimiento oficial de RSE. La información se obtuvo de 343 (trescientas cuarenta y tres) MIPyMES, mediante un cuestionario aplicado por entrevista. Los resultados que se obtienen indican que no hay una percepción única e integral de RSE, la mayoría de las MIPyMES están más interesadas en aspectos de orden financiero, comercial y legal, que en aspectos de orden social, ambiental o comunitario o bien en buscar obtener el distintivo oficial de RSE.
