Published: August 2022

BackgroundConstructing a reliable animal model for preclinical treatment of secondary lymphedema is challenging because the anatomical characteristics near the lymph nodes are understudied. Therefore, this study examined the detailed anatomical relationship between the axillary lymph node flaps (ALNFs) and brachial lymph node flaps (BLNFs) in the forelimb of Sprague-Dawley (SD) rats.Materials and methodsTen male rats, weighing 250–300 g, were used. The ALNFs and BLNFs on either side of the rat forelimbs were dissected. The two lymph node flaps (LNFs) were immediately harvested to analyze their physical characteristics (via imaging process software) and microscopic structure (via histology examinations).ResultsA total of 20 ALNFs and BLNFs from 10 rats were harvested and analyzed. ALNF dissection was simpler and lasted a shorter time than BLNF dissection (p &lt; 0.0001). The left LNFs were more difficult to dissect than the right LNFs (p &lt; 0.0001). In physical characteristics of LNFs, the area (p &lt; 0.001) of LNFs and the number of lymph nodes (p &lt; 0.0001) associated with ALNFs were greater than those associated with BLNFs, but the pedicle lengths of ALNFs were shorter than that of BLNFs (p &lt; 0.0001). No significant difference in the diameter of the venous and arterial pedicles was noted between the two LNFs (p &gt; 0.05).ConclusionThis study reported detailed physical characteristics of ALNFs and BLNFs in SD rat forelimbs, assessing the respective area of LNFs, number of lymph nodes, and lengths and diameters of vascular pedicles. Moreover, this study suggested an efficient method to perform a study of LNFs by describing the operation process and repeatedly measuring the operation time.

Objectives: Determine the changes in clinical, pharmacological and healthcare resource use parameters, between the 6 months prior to the lockdown and the 6 months following its end, in a population with hypertension who did not have a diagnosis of COVID-19.Methods: Real world data observational study of 245,979 persons aged &gt;16 years with hypertension in Aragon (Spain). Clinical (systolic-diastolic blood pressure, estimated glomerular filtration rate (eGFR), blood creatinine, cholesterol, triglycerides and anthropometric measures); pharmacological (diuretics, calcium channel antagonists, and ACE inhibitors); and utilization of healthcare resources were considered. We performed the Student’s T-test for matched samples (quantitative) and the Chi-squared test (qualitative) to analyze differences between periods.Results: SBP, DBP, parameters of renal function and triglycerides displayed a significant, albeit clinically irrelevant, worsening in women. In men only DBP and eGFR showed a worsening, although to a lesser extent than in women. Certain antihypertensive drugs and health-resource utilization remained below pre-pandemic levels across the 6 months post-lockdown.Conclusion: Changes in lifestyles, along with difficulties in access to routine care has not substantially compromised the health and quality of life of patients with hypertension.

The Neogene environment and paleovegetation of today’s semi-arid and arid Central Asia remain elusive. Little is known about the effect of paleoclimatic change on the distribution and ecological response mechanisms of aquatic plants, especially on the Tibetan Plateau. Here, we report a new species of Nelumbo Adanson, including leaves, receptacles, and fruits, namely Nelumbo delinghaensis sp. nov., from the Upper Youshashan Formation of the upper Middle Miocene in the northern Qaidam Basin on the Tibetan Plateau. The new species comprises centrally peltate leaves with 12–15 actinodromous primary veins and a receptacle embedded with ca. 15–30 fruits, with an unlobed central disc. Megafossils of lotus from northwest China broaden the geographical and stratigraphic ranges of Nelumbo. Our findings suggest that a large freshwater lake body surrounded by temperate forests and grassland developed in the Qaidam Basin during the late Middle Miocene, in sharp contrast to the present desert vegetation. The climate used to be sufficiently warm and moist enough to support a forest-steppe ecosystem with abundant freshwater bodies.

Published: August 2022

La necesidad de visualizar la relación entre la triada gestión, patrimonio y telecentros en Mayabeque es ineludible si se parte de que a lo largo de la historia no fue lo suficientemente gestionada desde la otrora Habana. Avanzar en cuanto a la conservación y salvaguarda de los bienes heredados es una responsabilidad de cada uno de los actores sociales en la provincia. Asimismo, la promoción y divulgación de cada uno de los bienes patrimoniales culturales y naturales forma parte del objeto social que poseen los telecentros en la provincia de Mayabeque. En este sentido, la presente investigación tiene como objetivo valorar la gestión en torno al patrimonio cultural y natural desde los telecentros en Mayabeque. Se han hecho indispensables para el estudio diversos métodos y procedimientos en el orden empírico y teórico, que posibilitaron el éxito de la misma. De manera general se realiza un abordaje teórico sobre las variables gestión, patrimonio cultural y natural y telecentros. Igualmente, se ofrece el análisis y discusión de las encuestas aplicadas a especialistas e instituciones como Telemayabeque, Telemar y Güines TV, pertenecientes a los municipios de San José de las Lajas, Santa Cruz del Norte y Güines respectivamente.

El presente trabajo tiene por objetivo analizar mediante un estudio teórico descriptivo la conservación de documentos en la Iglesia Pío IX de la ciudad de Portoviejo. Esta investigación comprende estrategias y técnicas específicas, relativas a la protección de los materiales tanto impresos como digitales, frente al deterioro, los daños y el abandono de los textos. La metodología es de tipo descriptivo; así mismo, se hace uso del análisis documental en la revisión de los presupuestos teóricos y del método histórico lógico para la organización de las ideas, con ello se estudian los aspectos que conducen a una aproximación conceptual para establecer una relación con las ciencias de la documentación. Además se brindan conclusiones destacando la factibilidad de contar con un documento que rija el trabajo de la institución facilitando los procesos de toma de decisiones del personal que labora en la organización y gestión documental. Entre los resultados se destaca el poco conocimiento para la conservación de documentos eclesiásticos en la iglesia Pío IX. Las conclusiones apuntan hacia la creación de un plan de preservación que contenga las directrices de preservación y la definición de parámetros específicos para mantener la documentación a través de los años.
El rol de los egresados de bibliotecología del cantón Rocafuerte a partir de las cuestiones éticas en el manejo de la información
Authors: Benavides Bailon Jeovanny , Solórzano  Vélez Rosario 
Published: August 2022

La práctica profesional de la bibliotecología atraviesa un período clave debido a profundas transformaciones que han estado motivadas por los cambios sociales, culturales y, sobre todo, tecnológicos. Por ello, lo ético se constituye en un eje transversal ante los nuevos desafíos de una sociedad en constante renovación. Resulta fundamental analizar la manera en que la sociedad se desarrolla a partir de nuevos retos y problemáticas, de igual forma las prácticas referentes a la bibliotecología y a la documentación. En el caso de este trabajo se analizan las cuestiones éticas en el manejo de la información y el rol que han cumplido los egresados de bibliotecología que pertenecen al cantón Rocafuerte y que laboran en instituciones de esta localidad. Las cuestiones a las que se han hecho referencia tienen relación con cinco aspectos puntuales: la incidencia de la ética, los principios de la ética bibliotecaria, las actitudes en el manejo de la información, las perspectivas de la ética bibliotecaria y a las “obligaciones” del bibliotecario. En este contexto, las necesidades profesionales requeridas por la sociedad deben ser analizadas, para contrastar lo teórico con la realidad.

La identidad universitaria en contextos de reclusión: del antagonismo al agonismo
Authors: Mora Gutiérrez Luis , Díaz Pontones Mónica 
Published: August 2022

Desde la filosofía política de Ernesto Laclau se retoma la categoría de antagonismo como el elemento nodal para la construcción de la identidad, antagonismo por parte de la institución penitenciaria y aun algunos grupos de internos que despliegan toda una seria de prácticas, valores y estrategias para impedir “ser” estudiantes universitarios; el ámbito carcelario y sus prácticas acotan otras formas de ser que no sea las de recluso-interno-delincuente, este antagonismo se resuelve en la fórmula “ellos o nosotros”. Ante este antagonismo originario, logramos mostrar como la presencia de la Universidad Autónoma de la Ciudad de México (UACM) con su Programa de Educación Superior en Centros de Reclusión del Distrito Federal (PESCER) introduce una dinámica diferente a la de la dinámica carcelaria, en tanto que todo proceso educativo no parte del “ellos o nosotros”, sino del “ellos y nosotros”; es la conjunción incluyente la que permite romper con las prácticas y valores de la institución carcelaria, volviéndose un espacio para el encuentro, la reunión, la construcción y no para la asimilación, desaparición o disolución de las diferencias e identidades, en estas prácticas también se ponen en juego la contingencia así como la decisión y la elección por parte de los universitarios. En esta construcción de la identidad universitaria se despliega también la pertenencia a una institución, la afiliación a ciertos valores y la construcción de nuevas prácticas y relaciones como comunidad universitaria.
Knowledge sharing challenges in hybrid knowledge work: Lessons from Denmark
Authors: Kirchner Kathrin , Ipsen Christine , Andersen Anders Reenberg 
Published: August 2022

During the COVID-19 pandemic, knowledge workers worked from home (WFH) and had to share knowledge mainly online. Studies show that remote work influence knowledge sharing. Beyond the pandemic, several studies report that companies expect more people to work partly or fully from home or anywhere. Therefore, we investigate how knowledge workers experience working from home (WFH), full or part-time, and how it affects their work and knowledge sharing.
We conducted an online survey at six different time points between May 2020 and November 2021, allowing us to analyse different working from home situations for the first time. Our survey included 23 questions covering positive and negative experiences from WFH and demographics. Data was collected from 3406 knowledge workers in Denmark working fully or partly from home.
The answers were analysed by fitting proportional odds logistic regressions. During the lockdown around February 2021, when Danish restrictions were high, knowledge workers reported that they could focus less on their work at home than at other points of time when they were allowed back in the office. Furthermore, they missed seeing their colleagues more during the lockdown period than at times when the society was completely open again, as they felt a lack of discussion and creative problem-solving. Despite using software solutions for collaboration and communication, knowledge workers missed opportunities for knowledge sharing when WFH. In general, during the whole period, female respondents reported that they got more time to focus on their work when WFH than males did. Finally, older respondents experienced more time to focus on work than the young respondents did when WFH.
The results show the differences in the situation of knowledge workers, whether it is enforced or flexible/voluntary to work from home. Thus, this study contributes to a better understanding of the challenges when knowledge workers WFH, which groups of knowledge workers can gain from WFH regarding efficiency and knowledge sharing needs. Beyond the pandemic, when companies want to offer more flexibility to WFH, this study provides conclusions on which conditions to be aware of to ensure efficient knowledge sharing.
Reconsidering Higher Education Organizations via ecosystem Thinking: Some Initial Thoughts

Published: August 2022

Providing optimal knowledge sharing has become increasingly important during the lockdown starting in early 2020. As a mechanism for sharing knowledge, education is also hugely impacted. Studying from home became feasible. On-campus learning had to change entirely to online within weeks. Besides preventing the spread of the virus, this shift allowed students to follow their courses anywhere. Physical distance to an institution is no longer a barrier to knowledge exchange. Online facilities offer students access to a broader field with an impact on the quality of education.
The paper defines an ecosystem for higher education institutions (HEI) based on our own experiences with online learning, interviews, and literature reviews.
The goal is to create a theorized environment where students can sign up for higher education (HE) classes, courses, programmes at different institutions across Europe. The ecosystem could create commonly shared quality standards from a decentralised perspective, potentially increasing learning quality and providing students with more freedom in their personal learning experiences. This paper does not serve as a full scientific proof but as a discussion.
The proposed ecosystem foresees students to follow courses anywhere. It offers study-abroad programmes and inter-institutional collaborations with a centralised platform for knowledge management. Allowing students to choose classes institution-free would increase specialisation of those institutions and impact the quality of education.
We will show that implementing a decentralised education system needs a bottom-up approach with a centrally formulated IT strategy to facilitate education exchange. Common quality standards, resilience, innovation, simplicity, inclusivity, maturity, and specificity are essential. For an adaptive system, governance, resistance, ownership, and communication ownership should adhere.
Our proposed ecosystem of institution-free HE would benefit all parties involved. Students can tailor their learning experience and obtain the highest level of education possible. HEI benefit in improving the quality of their programmes due to added competition. They could also drop courses that students better take elsewhere, allowing for specialisation in specific fields.
Such an ecosystem holds financial, administrative, and even legal limitations. However, institutions can implement step-by-step, giving affordance to the substantial bureaucracy that will inevitably ensue.
Multidimensionality of Knowledge in Strategic Innovation Processes of Enterprises in the Light of Research Results
Authors: ŁĘGOWIK-ŚWIĄCIK SYLWIA 
Published: August 2022

The publication raises the research question: what dimensions of knowledge are significant in strategic innovation processes of enterprises and what implications in this area can be observed in the case of enterprises of the logistics industry. By focusing on the use of the three dimensions of knowledge in the process of building strategic innovation, the strength and direction of the linear relationship between knowledge understood as the company’s ability to learn and strategic innovation was examined. In the counterpoint, the attention was drawn to the concept of ‘a sustainable enterprise’ which integrates knowledge and strategic innovation, providing the framework for the implementation of new solutions. This article is both a theoretical and practical contribution to the research into the determinants of strategic innovation in the context of the company’s ability to learn. The empirical research was based on the sample of 100 enterprises belonging to the logistics industry in Poland. The research period was the years of 2020-2021. The applied research methods were critical literature analysis, survey questionnaire and Pearson’s correlation analysis. The conclusions from the research suggest that along with an increase in knowledge in the surveyed enterprises there is an increase in innovation strategy in decision-making processes. Moreover, the publication deepens the understanding of various contexts of positive relationships between the three dimensions of knowledge and strategic innovation, which leads to the search for new implications in the changing economic environment. The subject of the significance of knowledge in strategic innovation processes of enterprises is important and up to date since it contributes to the discussion on the extent to which enterprises ought to implement knowledge to gain a competitive advantage.
Evolution of the Coordination of Activities Aimed at Building Knowledge in the Wikipedia Community
Authors: Skolik Sebastian 
Published: August 2022

The first decade of the 21st century spawned the intense development of online communities of practice. The largest knowledge-sharing communities were formed in several dozen language versions of Wikipedia. Defining rules for cooperation was necessary to ensure the desired content quality created by Wikipedians. It was essential to develop the appropriate initiatives, tools, and space for effective activity coordination within the service. Previous research in this area pointed to the role of leadership, group size, and tools facilitating work automation in creating actionable strategies and in the self-organization of work.
This paper aims to characterize the variability in creating new concepts of cooperation in selected language versions of Wikipedia and identify the factors of participating in various forms of cooperation. The author assumes that the greater number of initiatives a user enters contributes to an increase in their overall activity.
The research conducted was both qualitative and quantitative. A netnographic approach was used, as well as a statistical analysis of user activity records. Thanks to the netnographic research, the stages of Wikipedia’s evolution were identified. Quantitative research has shown a correlation between the number of activity areas (a user’s affiliation to WikiProjects) and their overall activity (the number of edits made). A change in Wikipedians’ activity style was also observed depending on their seniority on the website. The study’s conclusions may be helpful for organizations using crowdsourcing to achieve their own goals.
