Lymphatic filariasis, commonly known as elephantiasis is an infectious disease caused by parasitic filarial worms that are transmitted by mosquitoes. The global program to control and eliminate lymphatic filariasis is Mass drug administration (MDA). Brebes Regency is one of the endemic areas of filariasis in Central Java Province. MDA program has been implemented from 2017 to 2021. However, the results have not reached the national target. The level of cadres knowledge about filariasis MDA in Luwunggede community health center has never been studied. The purpose of this study is to describe knowledge of cadres about MDA filariasis in the Luwunggede Health Care. This study used a cross-sectional study design and proportional random sampling as a sampling technique with a sample size of 80 respondents. The results showed that respondents who had high knowledge (52.5%) were almost the same as respondents who had low knowledge (47.5%). Increase cadres' knowledge about filariasis and filariasis MDA through training is needed.

Background: The importance of patient safety competency in nursing students to enter the clinical environment has made continuous studies necessary. However, only few studies have been conducted to assess and compare patient safety competency and its related aspects among nursing students in various settings.Purpose: This study aimed to compare patient safety competency and its related aspects among undergraduate nursing students of two nursing schools.Methods: This descriptive comparative study was conducted at two nursing schools (A and B) in Iran. Using a census method, 240 undergraduate nursing students were enrolled from group A and 200 ones from group B. In total, 377 students completed the survey (response rate = 76.60 %). Data were collected using the adapted Health Professional Education in Patient Safety Survey (H-PEPSS). Data were analyzed using SPSS (version 21) and running descriptive statistics and independent samples t- test. The significance level was set at p<0.05.  Results: Results showed that nursing students’ means (SD) of patient safety competency in classroom (3.43(0.60)) and clinical setting (3.32(0.62)) were significantly higher in Group A compared with Group B (2.66(0.90) and 2.39(0.9), respectively). The means of the broader aspects of patient safety and comfortable speaking up about patient safety were significantly lower in Group A than Group B (3.58(0.71) and 3.31(0.59)) versus (3.79(0.71) and 3.55(0.72)).Conclusion: Nursing students from two different nursing schools had varied levels of patient safety competency in the classroom and clinical settings. In addition, it was found that the participants had different perspectives on aspects of patient safety and perceptions of speaking up about patient safety (p<0.05).

Published: September 2022

Background: Changes that occur in the life of older people during the COVID-19 pandemic present many challenges towards achieving better quality of life  However, only a limited number of studies that evaluate factors affecting the quality of life of older people during the COVID-19 pandemic are available.Purpose: This study aimed to identify the quality of life and factors affecting the quality of life of older people during the COVID-19 pandemic.Methods: This study employed a cross-sectional design using anonymous online questionnaires of 208 respondents who were selected using purposive sampling. This study was conducted during September to December 2020 in North Sumatra and Yogyakarta provinces. The QoL was measured using the World Health Organization Quality of Life (WHOQOL)-BREF questionnaire in the Indonesian version. The descriptive statistics were calculated for socio-demographics, while their association with quality of life was analyzed using Mann-Whitney and Kruskal-Wallis statistics. Multiple linear regression was used to determine the predictor factors affecting the quality of life of older people.Results: The results of the study showed that the mean and standard deviation for physical domain factors was 64.46(11.81); 64.61(11.98) for the psychological domain; 64.85(12.81) for the social domain, and 61.08(13.01) for the environmental domain. Factors significantly associated with the quality of life included age, retirement, living situation, health insurance, and medical history (p<0.05). However, the predictor factor affecting the quality of life of older people during the COVID-19 pandemic was medical history (β-value=0.25).Conclusion: Predictor factor affected the quality of life was medical history. The study suggests the government and health care professionals, specifically community health nurses, to promote the utilization of Integrated Elderly Health Service (IEHS) among older adults and families to maintain the quality of health.

Published: September 2022

Background: The COVID-19 public health crisis has caused disruptions in the continuum of Human Immunodeficiency Virus (HIV) services. Hence, HIV advocates and care providers must innovate to ensure the health and welfare of people living with HIV (PLHIVs) and other at-risk populations. There is a lack of empirical research that explores the experiences and perspectives of HIV volunteers in adapting to pandemic-related challenges.Purpose: This qualitative study aimed to describe the use of information and communications technology (ICT) in the provision of HIV services of Filipino volunteers during the pandemic. Methods: Qualitative descriptive study design was used, focusing on ICT use for HIV care. Sixteen (16) purposively selected volunteers from three community-based organizations (CBO) were interviewed using a semi-structured guide via videoconference. Inductive qualitative content analysis was used to draw insights from the data.Results: Findings revealed that volunteers used various ICTs such as social media, videoconferencing, dating sites, and online-based courier services to ensure continuity of HIV services. However, volunteers noted challenges in using ICT for HIV services, such as limited access to digital resources, increased work demands, and lack of human connection.Conclusion: Various tools and implementations of ICTs have been used by volunteers to ensure the continuity of services of PLHIVs. This study provides insights to nurses and informaticists in implementing digital technologies in caring for vulnerable clients during outbreaks like COVID-19.

Published: September 2022

Objective To investigate whether there is a link between cognitive function and motor reserve (i.e., individual capacity to cope with nigrostriatal dopamine depletion) in patients with newly diagnosed Parkinson’s disease (PD).Methods A total of 163 patients with drug-naïve PD who underwent 18F-FP-CIT PET, brain MRI, and a detailed neuropsychological test were enrolled. We estimated individual motor reserve based on initial motor deficits and striatal dopamine depletion using a residual model. We performed correlation analyses between motor reserve estimates and cognitive composite scores. Diffusion connectometry analysis was performed to map the white matter fiber tracts, of which fractional anisotropy (FA) values were well correlated with motor reserve estimates. Additionally, Cox regression analysis was used to assess the effect of initial motor reserve on the risk of dementia conversion.Results The motor reserve estimate was positively correlated with the composite score of the verbal memory function domain (γ = 0.246) and with the years of education (γ = 0.251). Connectometry analysis showed that FA values in the left fornix were positively correlated with the motor reserve estimate, while no fiber tracts were negatively correlated with the motor reserve estimate. Cox regression analysis demonstrated that higher motor reserve estimates tended to be associated with a lower risk of dementia conversion (hazard ratio, 0.781; 95% confidence interval, 0.576–1.058).Conclusion The present study demonstrated that the motor reserve estimate was well correlated with verbal memory function and with white matter integrity in the left fornix, suggesting a possible link between cognition and motor reserve in patients with PD.

People with cervical spinal cord injury (SCI) are likely to experience chronic intermittent hypoxia while sleeping. The physiological effects of intermittent hypoxia on the respiratory system during spontaneous sleep in individuals with chronic cervical SCI are unknown. We hypothesized that individuals with cervical SCI would demonstrate higher short‐ and long‐term ventilatory responses to acute intermittent hypoxia (AIH) exposure than individuals with thoracic SCI during sleep. Twenty participants (10 with cervical SCI [9 male] and 10 with thoracic SCI [6 male]) underwent an AIH and sham protocol during sleep. During the AIH protocol, each participant experienced 15 episodes of isocapnic hypoxia using mixed gases of 100% nitrogen (N2) and 40% carbon dioxide (CO2) to achieve an oxygen saturation of less than 90%. This was followed by two breaths of 100% oxygen (O2). Measurements were collected before, during, and 40 min after the AIH protocol to obtain ventilatory data. During the sham protocol, participants breathed room air for the same amount of time that elapsed during the AIH protocol and at approximately the same time of night. Hypoxic ventilatory response (HVR) during the AIH protocol was significantly higher in participants with cervical SCI than those with thoracic SCI. There was no significant difference in minute ventilation (V.E.), tidal volume (V.T.), or respiratory frequency (f) during the recovery period after AIH in cervical SCI compared to thoracic SCI groups. Individuals with cervical SCI demonstrated a significant short‐term increase in HVR compared to thoracic SCI. However, there was no evidence of ventilatory long‐term facilitation following AIH in either group.

The pattern of gonadotropin secretion along the estrous cycle was elegantly described in rats. Less information exists about the pattern of gonadotropin secretion in gonad‐intact mice, particularly regarding the follicle‐stimulating hormone (FSH). Using serial blood collections from the tail‐tip of gonad‐intact C57BL/6 mice on the first day of cornification (transition from diestrus to estrus; hereafter called proestrus), we observed that the luteinizing hormone (LH) and FSH surge cannot be consistently detected since only one out of eight females (12%) showed increased LH levels. In contrast, a high percentage of mice (15 out of 21 animals; 71%) exhibited LH and FSH surges on the proestrus when a single serum sample was collected. Mice that exhibited LH and FSH surges on the proestrus showed c‐Fos expression in gonadotropin‐releasing hormone‐ (GnRH; 83.4% of co‐localization) and kisspeptin‐expressing neurons (42.3% of co‐localization) of the anteroventral periventricular nucleus (AVPV). Noteworthy, mice perfused on proestrus, but that failed to exhibit LH surge, showed a smaller, but significant expression of c‐Fos in GnRH (32.7%) and AVPVKisspeptin (14.0%) neurons. Finally, 96 serial blood samples were collected hourly in eight regular cycling C57BL/6 females to describe the pattern of LH and FSH secretion along the estrous cycle. Small elevations in LH and FSH levels were detected at the time expected for the LH surge. In summary, the present study improves our understanding of the pattern of gonadotropin secretion and the activation of central components of the hypothalamic–pituitary‐gonadal axis along the estrous cycle of C57BL/6 female mice.

Authors: Metz Charlotte K. , Hinkson Larry , Gebauer Bernhard , Henrich Wolfgang
Published: September 2022

Objectives

Uterine artery pseudoaneurysm (UAP) is a rare but sinister complication during pregnancy. Diagnosis can be made by color Doppler ultrasound. Previous abdominal- and obstetric surgery increase the risk for UAP formation.

Case presentation

We present a case of a 36 year young healthy women, presenting at 27 weeks of gestation with acute lower abdominal pain. UAP was detected by color Doppler ultrasound. An endovascular coil embolization was performed, with good maternal and fetal outcome. Furthermore, a review of the literature looking at UAP embolization in pregnancy was performed.

Conclusions

UAP is reported to appear as a complication of endometriosis. UAP should be treated by endovascular coil embolization, which is a safe and with almost 100% success rate an effective treatment during pregnancy.
Prototypical associations in the production of words in English as a foreign language by L2 learners
Authors: Mora Jaqueline
Published: September 2022

This ongoing study attempts to explore the role semantic prototypes play in response to the production of words of a semantic category by two groups of learners differing in age and language level. Our main objectives point to i) the identification of the number of words produced in English regarding semantic prototypes by the groups of informants; ii) the analysis and comparison of the similarities and the differences of the prototypical associations provided by learners of different ages and different language levels; iii) the evidence of the universality of prototypes through the convergences and/ or divergences collected in the sample. The data collection instruments considered for this ongoing study are a background questionnaire and a productive semantic categorization task. Findings yielded that (i) there is evidence of prototype responses, and they are exclusively associated with the basic level of categorization; (ii) children retrieved fewer prototypical and non-prototypical words than adolescents in a lexical availability test; (iii) convergences and divergences are shown in the words retrieved by the two groups differing in age and language level. This study aims to evolve the dynamics of prototypical associations in language, and their linguistic, social, and cultural implications in communication when learning a foreign language.
Development of students’ spoken language in an online French course: Presentation of continuing doctoral research
Authors: Nerušilová Terezie
Published: September 2022

The present paper describes continuing doctoral research which examines the development of oral language during an online French course in terms of complexity, accuracy and fluency (CAF), and reflects on the possible influence of the online intervention on this development. The research is designed as a multiple-case study with 11 university students as participants of the research, each student forming a single case of the study. The pre-test post-test design was chosen in order to analyse students’ spoken performance before and after the intervention, and thus to assess its development. The paper outlines the results of accuracy analysis, which indicate that language performance cannot be judged solely by one aspect of CAF: many errors identified in this research seem to be a sign of the use of more complex language; and precise and accurate language without errors does not seem to be complex or fluent. The number of phonetic errors and some replies in the interviews suggest that the online course did not place enough importance on the teaching of pronunciation. These suppositions will be tested in the next stages of the research. The paper is part of the AILA Europe special issue.
How to use oral multimodal corpora and data-driven learning to teach French Talk-in-Interaction
Authors: Cousinard Clara
Published: September 2022

This paper presents one aspect of our ongoing research in the context of a doctoral thesis. We focus on the use of multimodal oral corpora to develop the interactional skills of learners of French as a foreign language (André 2018, Ravazzolo and Etienne 2019). To do so, we compiled a list of interactional difficulties through a survey of 20 researchers and French as a Foreign Language teachers. After that, we created a learner corpus to check whether the difficulties brought up in the survey were present in learners’ productions, and to narrow down our results. To better analyze this corpus, we conducted self-confrontations so that we could have input directly from the learners. The objective was to identify interactional difficulties that could be the object of data-driven learning (Johns 1991) sessions with intermediate-level learners of French as a Foreign Language. The paper is part of the AILA Europe special issue.
On the way to plant data commons – a genotyping use case
Authors: Feser Manuel , König Patrick , Fiebig Anne , Arend Daniel , Lange Matthias , Scholz Uwe
Published: September 2022

Over the last years it has been observed that the progress in data collection in life science has created increasing demand and opportunities for advanced bioinformatics. This includes data management as well as the individual data analysis and often covers the entire data life cycle. A variety of tools have been developed to store, share, or reuse the data produced in the different domains such as genotyping. Especially imputation, as a subfield of genotyping, requires good Research Data Management (RDM) strategies to enable use and re-use of genotypic data. To aim for sustainable software, it is necessary to develop tools and surrounding ecosystems, which are reusable and maintainable. Reusability in the context of streamlined tools can e.g. be achieved by standardizing the input and output of the different tools and adapting to open and broadly used file formats. By using such established file formats, the tools can also be connected with others, improving the overall interoperability of the software. Finally, it is important to build strong communities that maintain the tools by developing and contributing new features and maintenance updates. In this article, concepts for this will be presented for an imputation service.

Published: September 2022

In this study, the size effect of zircon (ZrSiO4) on the tribological characteristics of polymer matrix friction composites were investigated. Hence, four friction composites containing micro and nano-sized zircon particles (5 and 10 wt%) were developed and produced using powder metallurgy method. Their wear and friction characteristics were examined using a friction-wear test device. The weight loss and specific wear rate were measured and compared with that obtained for microsized zircon particles. The surfaces of samples were analyzed using a scanning electron microscope, and less wear was observed in the samples containing nano-sized zircon particles. The results revealed that the size of abrasive particles plays a key role in enhancing the friction coefficient and friction stability.

Published: September 2022

Astronomical devices, such as optical benches, carry high precision instrumentation work at low temperatures (−150 °C). To fulfill engineering requirements, glass-epoxy composite trusses are proposed. To evaluate the performance of this solution, thermomechanical characterization is carried out by means of dynamic mechanical analysis (DMA), thermogravimetric analysis (TGA), flammability tests, and tensile test and Scanning Electron Microscopy (SEM) observations. Two family of coupons are tested; first one environmentally aged for 10 years and second one recently fabricated, both at 20, 0 and −20 °C. Ageing influence is more noticeable on thermal behavior as Tg and self-extinguish capacity are lower. Ultimate tensile strength and maximum strain are lower for the aged coupons (16–25%), but there is not a remarkable difference in terms of stiffness. Also, coupons mechanically tested at −20 °C show a slight increment in strength. These results show that ageing of glass-epoxy composites must be considered when high performance devices are conceived to be fabricated with.
Burying the Heros: Identifying the Archaeological Background of the Homeric Burial
Authors: Kourkoulakos Antonis
Published: September 2022

For centuries the Homeric epics, especially the Iliad, have fascinated and attracted the attention of the academic community and the wider public alike. Many scholars throughout the centuries endeavored to prove the historicity of the Iliad through the archaeological evidence. Though current academic research has long departed from those approaches, the epics contain important historical and cultural elements that were part of the reality not only of Homer’s contemporary (Iron Age) society but also, to an extent, of the Late Bronze Age. This paper argues that the Homeric funerary customs are not a purely literary creation, but rather the result of a mixture of traditions, contemporary customs and collective memory. This will be achieved through a survey of archaeological and written evidence pertaining to Late Bronze Age and Iron Age burial traditions, ranging from Hittite Anatolia to Central Europe, and in doing so suggest the possible origins, both geographically and chronologically, of ‘Homeric’ mortuary practices.
Byzantine or Western European inspirations? Monumental architecture on the borderlands: the case study of medieval Chełm (south-east Poland)
Authors: Buko Andrzej
Published: September 2022

Chełm – located today on the Polish-Ukrainian border –for over a century has attracted the attention of numerous scholars. The town had been rebuilt by Daniel Romanovich, the Halych-Volhynian prince who was crowned in 1253 by Pope Innocent IV and recognized as the king of Ruthenia – which was an unusual event in medieval Europe. For here we have a ruler who belonged to the Orthodox Church accepting a papal crown and the Catholic faith. In such circumstances, some time before the middle of the 13th century, Daniel decided move his seat from Halych to Chełm, situated on the western periphery of his domain. The new city became not only a main seat, but also the real capital of the Halych-Volhynian Princedom. Here, on Cathedral Hill, excavations revealed the remains of the medieval basilica and a multi-element residence. At the same time, new discoveries were made in the city outskirts – namely, two masonry towers and an enigmatic column. The interdisciplinary archaeological research carried out by the author show an architectural complex and many archaeological finds unique in this part of Europe, ones inspired by the traditions of ancient Rome, the Byzantine East, and patterns known at that time in the Latin West.
Attitudes Toward Global and Local Consumer Culture and the Meanings of Brands
Authors: Kim Jung Seek
Published: September 2022

While the rapid worldwide integration has facilitated the emergence of global consumer culture (GCC), local consumer culture (LCC) still holds a strong influence. Brands, be they global or local, are critical marketplace resources in consumer culture for constructing individual and collective identities. As attitudes toward GCC and LCC guide consumers’ choice between global and local brands, the article addresses which brand meanings (functions) drive the choice and use of brands by consumers embracing GCC/LCC. Theoretically, I advance the literature by connecting GCC/LCC and reactions to brand stimuli. Specially, I examine correlations between the two attitudinal constructs and the salience of four brand meanings: quality, personal identity (self-identity, group-identity, and status), values (similar to social responsibility), and traditions. The results suggest that global brands should focus on personal identity, but not quality in positioning and communications. Local brands should develop their iconic status through ties with tradition and heritage, but not by personal identity. Thus, personal identity and traditions are the most important brand associations to be utilized by global and local brands.
Politeness, performance, and pointing: gesture in Chinese reality television
Authors: Schleh Lysander
Published: September 2022

This study examines the use of gesture by participants of the reality television show Sisters Who Make Waves. Based on 23.5 h of footage involving 30 participants, the analysis focuses on gestural communication by the female participants, who must straddle a formal/informal communicative environment dictated by the medium of reality television. More specifically, I examine two features of pointing gestures by the participants: social parameters and context constraints. The main interest is how a combination of general cultural norms as well as considerations of the interlocutor’s social status contribute to gesture use. Context constraints and pragmatic concerns are also analyzed regarding the choice of manual or non-manual pointing gestures. These factors are seen to play a strong role in gesture choice. The findings show that the participants are sensitive to these social and contextual variables, especially regarding concepts like saving face, politeness, and friendly intimacy.

Authors: Yan Xuemei , Dai Zhihui , Wu Qianhui , Wang Xiaolei , Wang Yan , Zeng Ge , Wu Yanpeng , Chen Shengbao , Yi Lan , Yu Hongjie , Gao Lidong
Published: September 2022

Objective:

This study was aimed at investigating the effectiveness of inactivated COVID-19 vaccines against the Delta variant.

Methods:

We performed a retrospective cohort study of close contacts of people with laboratory-confirmed SARS-CoV-2 infections in Hunan province, China, from July to August 2021. Mixed-effect logistic regression was used to estimate vaccine effectiveness (VE), and analyze the effects of the vaccination status of index cases and the exposure risk level on VE estimation.

Results:

A total of 1,685 close contacts of 126 index cases were included; 835 (49.6%) had received two doses of inactivated vaccines, and the median interval between the 2nd dose and exposure was 48 days (IQR: 41 to 56 days). Full vaccination was defined as two doses at least 14 days before exposure. Adjusted VE estimates for full vaccination were 54.8% (95% CI: 7.7 to 77.9) and 68.4% (95% CI: 8.5 to 89.1) against symptomatic and moderate-to-severe COVID-19, respectively. VE for inactivated vaccines was difficult to observe if index cases had been fully vaccinated. The estimated VE with respect to infection protection was lower among household than non-household contacts.

Conclusion:

Complete primary immunization of two-dose inactivated COVID-19 vaccines protected against SARS-CoV-2 Delta variant infection. Infection risk was higher among vaccinated household contacts than vaccinated non-household contacts.

Aging and neurodegenerative diseases lead to decline in thinking and memory ability. The subfields of the hippocampus (HCsf) play important roles in memory formation and recall. Imaging techniques sensitive to the underlying HCsf tissue microstructure can reveal unique structure–function associations and their vulnerability in aging and disease. The goal of this study was to use magnetic resonance elastography (MRE), a noninvasive MR imaging-based technique that can quantitatively image the viscoelastic mechanical properties of tissue to determine the associations of HCsf stiffness with different cognitive domains across the lifespan. Eighty-eight adult participants completed the study (age 23–81 years, male/female 36/51), in which we aimed to determine which HCsf regions most strongly correlated with different memory performance outcomes and if viscoelasticity of specific HCsf regions mediated the relationship between age and performance. Our results revealed that both interference cost on a verbal memory task and relational memory task performance were significantly related to cornu ammonis 1–2 (CA1–CA2) stiffness (p= 0.018 andp= 0.011, respectively), with CA1–CA2 stiffness significantly mediating the relationship between age and interference cost performance (p= 0.031). There were also significant associations between delayed free verbal recall performance and stiffness of both the dentate gyrus–cornu ammonis 3 (DG–CA3;p= 0.016) and subiculum (SUB;p= 0.032) regions. This further exemplifies the functional specialization of HCsf in declarative memory and the potential use of MRE measures as clinical biomarkers in assessing brain health in aging and disease.

SIGNIFICANCE STATEMENTHippocampal subfields are cytoarchitecturally unique structures involved in distinct aspects of memory processing. Magnetic resonance elastography is a technique that can noninvasively image tissue viscoelastic mechanical properties, potentially serving as sensitive biomarkers of aging and neurodegeneration related to functional outcomes. High-resolutionin vivoimaging has invigorated interest in determining subfield functional specialization and their differential vulnerability in aging and disease. Applying MRE to probe subfield-specific cognitive correlates will indicate that measures of subfield stiffness can determine the integrity of structures supporting specific domains of memory performance. These findings will further validate our high-resolution MRE method and support the potential use of subfield stiffness measures as clinical biomarkers in classifying aging and disease states.
The Río Grande–Río Bravo Basin: Water Cultures and Water Systems in a Fragile Eco‐Zone
Authors: Saldaña Tomás Martínez
Published: September 2022

There is an environmental crisis now facing the inhabitants of the Río Grande—Río Bravo Basin which lies along the border between the south of New Mexico and the west of Texas in the U.S., and Chihuahua, Coahuila, Nuevo León and Tamaulipas in northern Mexico. This essay examines social, cultural and technological aspects of a water system that had for a long time provided a sustainable living environment in the Basin. We now have a collection of rich information on water rights, irrigation systems, and forms of social organization that emerged with the irrigation systems and on acequia culture that includes festivities and celebrations that tie into the irrigation calendar. A key aspect of the system was that water was a community, not private possession, an arrangement that endured for a longer time on the U.S. rather than the Mexican side of the border. The 20th century saw the destruction of the irrigation‐based agricultural system, resulting in today's environmental crisis. The author calls for a return to a sound and sustainable water management system for this fragile border region.

The article presents motifs of Podlasie and Białystok in the early collections of writings by Joanna Siedlecka, which had been published first in her debut Stypa (1981) and later also in Poprawiny and Parszywa sytuacja (both 1984). The article concludes that Siedlecka does not rely on clichéd storylines in her writings about Podlasie. She also avoids ideological rhetoric and with irony punctuates the absurdity of everyday life in Communism.
Różne oblicza literackich przewodników po miastach
Authors:   Instytut Filologii Polskiej, Uniwersytet Wrocławski, Gałecki Wojciech
Published: September 2022

The article attempts a literary analysis of certain aspects of texts that belong to the so-called geoliterature, here referred to as “literary city guides”. The author analyzes three different texts, corresponding to three descriptive strategies adopted in the books. The first, Praga z Hrabalem [Prague with Hrabal] by Tomaˇs Mazal, represents the “creator’s perspective”, and it deploys a guidebook narrative to tell a biography of an author. Next guidebook, Dublin z Ulissesem [Dublin with Ulysses] by Piotr Paziński, concentrates on a specific literary work and invites the reader to explore it with the help of special scenarios. The third, Mariusz Szczygieł’s Osobisty przewodnik po Pradze [A Personal Guide to Prague], is an “authorial guide” which presents a unique personal perspective on the city. Summing up the analysis of guide strategies, the author of the article signals the possibility of looking at guide-related practices as a kind of model for literary studies.

Published: September 2022

The article interprets the novel Przewóz (2021) written by Andrzej Stasiuk. The author narrates two stories: an autobiographical essay about the contemporary perspective of the Polish reality and a historical plot unfolding in the border territory by the river Bug in 1941. The main themes of the novel include myths of collective consciousness, the past and present of rural spaces, the critique of common opinions concerning World War 2 and the Holocaust, as well the theme of a border as influencing human life and identity in both, figurative and substantial aspects.
Experiencia en tecnología-educación-innovación: una mirada desde el Cinndet-UPN Colombia
Authors: Ortegón Moreno Jhonny Alexander
Published: September 2022

El artículo tiene por objetivo presentar la sistematización de la experiencia del Centro de Innovación y Desarrollo Educativo y Tecnológico —Cinndet— a propósito de las dinámicas emergentes que trajo consigo la pandemia de covid-19 en los escenarios educativos; estas dinámicas no hicieron distinción en los diferentes niveles académicos, desde la experiencia del Cinndet. Así pues, se presenta el referente conceptual y misión institucional del centro y cómo se articula la tecnología, la educación y la innovación en los procesos comunicativos de los profesores en formación y en ejercicio. En consecuencia, las actividades de gestión del conocimiento discriminadas en tres estrategias, que llevó a cabo el Cinndet en el año 2020, fueron una alternativa en la capacitación permanente del profesorado en temas relacionados con la educación virtual a partir de webinar, tutoriales, capacitaciones, uso de la plataforma Moodle y material didáctico, como parte del acompañamiento en el quehacer docente.

Published: September 2022

El covid-19 llegó para cambiar el mundo y, en especial, los procesos de enseñanza y aprendizaje tanto en el ámbito empresarial como en el educativo. Las universidades en sus programas presenciales tuvieron que recurrir a herramientas tecnológicas, que permitieran mediar la interacción entre estudiantes y docentes; esto represento un desafío para los docentes al incorporar en sus procesos de transferencia de conocimiento el uso de los entornos virtuales de aprendizaje. Se necesita de un liderazgo electrónico que ayude y promueva la adaptabilidad de esta nueva forma de trabajo en la educación superior. Este artículo tiene como objetivo describir la experiencia de diseño de entornos virtuales de aprendizaje para las asignaturas de Aprendizaje Organizacional y Gestión del Conocimiento e Innovación en el primer y segundo periodo académico de 2020. El texto se desarrolla a través de la narrativa del profesor y estudiantes, sobre el uso y apropiación de conceptos del liderazgo electrónico para el proceso de enseñanza en el aula virtual de aprendizaje.
Diseño de un videojuego educativo como estrategia didáctica para el desarrollo de habilidades lógico matemáticas en estudiantes de primer ciclo escolar
Authors: Bohórquez Ramírez Gabriela
Published: September 2022

Durante los últimos años, la industria de los videojuegos ha superado el contexto del entretenimiento y se puede contemplar como un componente lúdico que se integra a los modelos de aprendizaje, y beneficia el desarrollo y consecución de competencias, destrezas y habilidades específicas a través del planteamiento de nuevas estrategias de enseñanza-aprendizaje que trascienden las prácticas de la educación tradicional. Sin embargo, pese al crecimiento exponencial de esta industria, las instituciones educativas continúan oponiéndose a incorporar sistemáticamente estos entornos de entretenimiento en los planes de estudio, ignorando las grandes posibilidades didácticas y creativas que estos poseen. De esta manera, la presente investigación pretende respaldar la implementación de los videojuegos desde una perspectiva educativa orientada al desarrollo de habilidades lógico matemáticas en estudiantes de primer ciclo académico, para demostrar el beneficio de su integración en el proceso de aprendizaje; esto, a través de un enfoque investigativo relacionado con las ciencias computacionales y las ciencias en educación, haciendo uso de la propuesta del videojuego “The Treasure Hunter and The Island of Numbers”.
Recommendations for Prevention and Control of Influenza in Children, 2022–2023
Authors:   COMMITTEE ON INFECTIOUS DISEASES
Published: September 2022

This technical report accompanies the recommendations of the American Academy of Pediatrics for the routine use of influenza vaccine and antiviral medications in the prevention and treatment of influenza in children during the 2022 to 2023 season. The American Academy of Pediatrics recommends annual influenza vaccination of all children without medical contraindications starting at 6 months of age. Influenza vaccination is an important strategy for protecting children and the broader community as well as reducing the overall burden of respiratory illnesses when other viruses, including severe acute respiratory syndrome-coronavirus 2, are cocirculating. This technical report summarizes recent influenza seasons, morbidity and mortality in children, vaccine effectiveness, and vaccination coverage, and provides detailed guidance on storage, administration, and implementation. The report also provides a brief background on inactivated and live attenuated influenza vaccine recommendations, vaccination during pregnancy and breastfeeding, diagnostic testing, and antiviral medications for treatment and chemoprophylaxis. Updated information is provided about the 2021 to 2022 influenza season, influenza immunization rates, the effectiveness of influenza vaccination on hospitalization and mortality, available vaccines, guidance for patients with history of severe allergic reactions to prior influenza vaccinations, and strategies to promote vaccine uptake.
Espacios para la sociabilidad, comunicación de noticias y rumores en las guerras de independencia de México y Venezuela (1809-1818)
Authors: Castellón Valdéz Luz Mary
Published: September 2022

Objetivo: este artículo analiza los espacios de sociabilidad informal y la comunicación de noticias y rumores en el contexto de las guerras de independencias de México y Venezuela entre 1809 y 1818, con el fin de comparar la importancia que estos tuvieron en el desarrollo de los acontecimientos. Metodología: esta es una investigación de tipo documental y cualitativa, desde una perspectiva historiográfica comparativa. Se estudian fuentes primarias de la época derivadas de una selección de varios testimonios incluidos en los expedientes de infidencia. Originalidad: se comparan hechos y situaciones discursivas específicas que buscan dar luces sobre las estrategias utilizadas por los habitantes de estos dos territorios en el desarrollo del conflicto armado. Conclusiones: se muestra la utilidad que adquirieron los “rumores” y las noticias esparcidas —tanto por medios escritos como a través del “voz a voz”—, como una estrategia pensada para la propagación de información y seducción hacia la causa insurgente en el contexto de las guerras independentistas en ambos territorios. Esto se puede percibir como la expresión de una incipiente “opinión pública” y una cultura política que también formaba parte o se diseminaba en entornos absolutamente sociales, como serían los espacios de la sociabilidad informal de la época.
Norbert Elias leído por Steven Pinker: el problema del desarrollo cognitivo en la historia cultural
Authors: Lara Wilson
Published: September 2022

Objetivo: este artículo analiza la recepción de la perspectiva psicogenética de Norbert Elias dentro de la llamada psicología evolutiva de Steven Pinker, quien, a diferencia de otros herederos de las ideas eliasianas, no solo encuentra relevante la teoría del sociólogo alemán en lo relativo a la postura figuracional, sino sobre todo en lo referente a su forma de conceptualizar el desarrollo histórico de las estructuras psíquicas. Metodología: con base en la comparación de fuentes editadas, se precisa hasta qué punto la visión procesual del pensamiento de Elias ha logrado establecerse y ser continuada en la orientación académica defendida por Pinker. Originalidad: la comparación de las obras de Elias y Pinker abre la oportunidad de explorar la recepción del pensamiento de Norbert Elias como un problema cognitivo propio de la actual fase del desarrollo social. Conclusión: se sugiere que las similitudes y diferencias en la forma en que ambos autores delimitan el desarrollo cognitivo de la humanidad como problema de estudio tiene consecuencias profundas sobre la conceptualización de la historia de la cultura.
