Tecnologías de la comunicación en la relación enseñar-aprender: un escenario para la formación de la docencia universitaria
Authors: Guevara Venus , López Rafael 
Published: February 2023

El presente trabajo tiene como propósito develar a partir del modelo de Bronfenbrenner el significado que emerge de la configuración de aprendizajes generado en el espacio de la experiencia y representaciones de la práctica docente universitaria con el uso de las tecnologías de la comunicación. La referida práctica estuvo enmarcada en la política institucional contemplando numerosos aspectos que van cernidos desde los medios y la mediación del proceso educativo, la necesidad de transformación del entorno conjuntamente con la reconfiguración de la docencia universitaria acordes con las tendencias actuales de la realidad. Para el alcance de esta meta el fenómeno en estudio se abordó a partir del paradigma cualitativo, emergiendo el método fenomenológico hermenéutico la interpretación realizada. Las semblanzas referenciales epistémicas se encuentran representadas por principios filosóficos que en su esencia caracterizan los paradigmas y la racionalidad con que se operan los métodos en la búsqueda de conocimiento. El análisis refleja una tendencia clara de la educación superior hacia la personalización, el aprendizaje autónomo, la colaboración y el aprendizaje a lo largo de la vida profesional con relación a las tecnologías. No obstante, siguen existiendo retos en el uso de tales tecnologías ya que la integración requiere de un diseño pedagógico para que su aplicación conlleve prácticas efectivas. Las reflexiones y consideraciones del estudio se evidencia que el uso de las tecnologías de comunicación (Tic, Tac, Tec) en la relación enseñar-aprender da mayor fuerza a la idea hacia el desarrollo personal y profesional propiciando un escenario para la formación continua en materia tecnológica de la docencia universitaria.

Introduction:
Extremity injuries are a leading cause of morbidity in low- and middle-income countries (LMICs), often resulting in marked short-term and long-term disabilities. Most of the existing knowledge on these injuries originates from hospital-based studies; however, poor access to health care in LMICs limits these data because of inherent selection bias. This subanalysis of a larger population-level cross-sectional study in the Southwest Region of Cameroon aims to determine patterns of limb injury, treatment-seeking behaviors, and predictors of disability.

Methods:
Households were surveyed in 2017 on injuries and subsequent disability sustained over the previous 12 months using a three-stage cluster sampling framework. Subgroups were compared using the chi square, Fisher exact, analysis of variance, Wald, and Wilcoxon rank-sum tests. Logarithmic models were used to identify predictors of disability.

Results:
Of 8,065 subjects, 335 persons (4.2%) sustained 363 isolated limb injuries. Over half of the isolated limb injuries (55.7%) were open wounds while 9.6% were fractures. Isolated limb injuries most commonly occurred in younger men and resulted from falls (24.3%) and road traffic injuries (23.5%). High rates of disability were reported, with 39% reporting difficulty with activities of daily living. Compared with individuals with other types of limb injuries, those with fractures were six times more likely to seek a traditional healer first for care (40% versus 6.7%), 5.3 times (95% CI, 1.21 to 23.42) more likely to have any level of disability after adjustment for injury mechanism, and 2.3 times more likely to have difficulty paying for food or rent (54.8% versus 23.7%).

Discussion:
Most traumatic injuries sustained in LMICs involve limb injuries and often result in high levels of disability that affect individuals during their most productive years. Improved access to care and injury control measures, such as road safety training and improvements to transportation and trauma response infrastructure, are needed to reduce these injuries.

O leite materno sofre diversas modificações quanto aos seus nutrientes ao longo do período de lactação de acordo com as necessidades do recém-nascido ocorre essas mudanças, é notório esse processo quando se compara o leite materno do recém - nascido termo com recém nascidos de pré-termo que possui maior concentração de alguns nutrientes como: lipídios e proteínas. Sendo esse um dos fatores que fazem do leite materno o alimento mais recomendado para qualquer recém- nascido, principalmente se a criança for mais frágil como é o caso dos nascidos pré-termo. No entanto, ao longo dos anos, várias pesquisas foram realizadas e constataram que o leite humano pré-termo após o primeiro mês de amamentação, a concentração de proteína e de vários outros nutrientes são insuficientes para a maioria dos prematuros. Com isso surgiu a necessidade de se acrescentar fortificantes ao leite materno, que são compostos de: proteínas, carboidratos, gorduras e/ou minerais, em apresentação líquida ou em pó. Este artigo tem como objetivo realizar uma busca de informações e referenciais teóricos, em forma de revisão sistêmica, abordando a importância do uso de aditivos do LH, bem como a composição e os benefícios dos aditivos. Analisando os artigos sobre o tema, nota - se um consenso que a utilização dos aditivos ao leite humano melhorar seus aspectos nutricionais, assim ocorrendo maior ganho de peso, crescimento e perímetro cefálico dos recém nascidos pré-termo.

Love for the Disappearing: On Ice, Warming and Self-criticism in two Climate-Change Novels
This article focuses on the configuration of the love of ice in two novels from the emergent field of climate-change fiction: The Ice Lovers (2009) by the Canadian author Jean McNeil, and Eis Tau (2011) by the Austrian author Ilija Trojanow. Both these works end with the suicide of the main character; a commonality which serves as the point of departure for this article. Additionally, the main characters’ love of ice is explored as a means of being-in-the-world, as opposed to the being-in-the-world of a humanity that is generally depicted as treating nature without love, i.e., unsustainably. In this regard the novels are also read as a site of self-criticism (or anthropocritique). In its pursuit of these two contrasting forms of being-in-the-world, the article draws heavily on the philosophy of Martin Heidegger. The ecological aspects of Heidegger’s philosophy have been firmly criticized by eco-critics and philosophers alike. However, as this article makes clear, Heidegger’s line of thought can still be detected in current writing on climate change.

Poetry in the Age of the Arms Race: Ingrid Sjöstrand’s Poem “Otänkbart” (“Unthinkable”) on the NATO Rearmament Decisions of 1979
Within the popular movements poetry is used as a tool in the struggle for social and political change. The poetry cherished by the movements can thus be described as utilitarian, performing rhetorical functions in relevant contexts. The article deals with the poem “Otänkbart” (“Unthinkable”) by Ingrid Sjöstrand, which addresses a pertinent social problem from the perspective of the peace movement. The poem was published in Dagens Nyheter, Sweden’s largest daily newspaper, on 28 December, 1979. It is a response to the NATO decision made at a summit conference in Brussels on 12 December of that year to deploy nuclear weapons in Europe. A theoretical basis for the analysis is provided by Ron Eyerman and Andrew Jamison’s cognitive approach to social movements. In my study, I consider “Unthinkable” as part of the peace movement’s cognitive practice, exploring the explanation of the arms race formulated in the poem. I also investigate the relationship of the poem to articles published in Dagens Nyheter in December 1979 concerning the NATO decision, as well as to other texts dealing with related themes. Further, I scrutinize the poem’s uses of rhetorical devices and strategies to convince the reader to adopt the peace movement’s position on the issue and to create commitment and readiness to act. The analysis shows that “Unthinkable” was clearly a part of the peace movement’s knowledge production concerning the causes and consequences of the arms race, and of the movement’s values and alternative strategies for action. Structurally, “Unthinkable” offers creative opportunities for committed reception.

Enduring Contingency: Remarks on the Precariousness of Liberal Democratic Law
Van der Walt, in my reading, suggests that enduring contingency, in the twofold sense of an enduring state of contingency and of contingency as what needs to be endured, justifies the central role of the majority/minority principle in liberal democratic law. Does this endorsement of the principle go far enough in addressing the radical challenge of contingency? What about those cases in which a group refuses to understand itself as a disaffected minority in conflict with a majority, hence as part of a unity, even if only the unity of a legal order? At issue is a group that demands exclusion from a polity rather than demanding its recognition and inclusion as a minority entitled to be treated as equal to, even if different from, the majority. I suggest that, in the end, Van der Walt justification of the majority/minority principle espouses an agonistic defence of political and legal unity.

How Do We Make Liberal Democratic Law Together? Remarks on Van der Walt’s Notion of a ‘Diffuse We’
In the last section of the article ‘Rawls, Habermas and Liberal Democracy,’ Van der Walt introduces the notion of a ‘diffuse we’ to delineate the role that constituent power plays in his account of liberal democratic law. This contribution raises questions about Van der Walt’s understanding of a liberal democratic community as a plural self. The first part of the article reviews some of the core passages of his The Concept of Liberal Democratic Law to highlight the different accounts of the unity of a liberal democratic community, which Van der Walt rejects. The last part of the paper questions the (epistemic) conditions under which the ‘diffuse we’ proposed by Van der Walt can socially cooperate and express a shared commitment to be bound by liberal democratic norms.

Published: February 2023

Background: Structural equation modeling (SEM) is a widely used quantitative technique among social and management science researchers. Self-reported questionnaires are in prevalent use among researchers in pharmacy management. But validity and measurement invariance measures of questionnaires are not commonly reported in research studies.
Objectives: To determine the construct validity and invariance validity of the research instrument. To provide guidelines for applying confirmatory factor analysis (CFA) in pharmacy management research.
Methods: A cross-sectional study with an anonymously structured questionnaire randomly administered to six hundred community pharmacists in southwestern, Nigeria. The CFA algorithm in SEM software was used to develop a measurement model and test hypotheses.
Results: The measurement model satisfied the model and construct validity benchmarks. The measurement invariance parameters were adequate.
Conclusion: The study concluded that the theoretically developed constructs- economic, operational, and social performance were valid representations of theory. Mandatory inclusion of validity and measurement invariance test reporting in pharmacy management research is advocated.

AbstractThe growing interest in nanomedicine over the last 20 years has carved out a research field called “nanocatalytic therapy,” where catalytic reactions mediated by nanomaterials are employed to intervene in disease‐critical biomolecular processes. Among many kinds of catalytic/enzyme‐mimetic nanomaterials investigated thus far, ceria nanoparticles stand out from others owing to their unique scavenging properties against biologically noxious free radicals, including reactive oxygen species (ROS) and reactive nitrogen species (RNS), by exerting enzyme mimicry and nonenzymatic activities. Much effort has been made to utilize ceria nanoparticles as self‐regenerating antioxidative and anti‐inflammatory agents for various kinds of diseases, given the detrimental effects of ROS and RNS therein that need alleviation. In this context, this review is intended to provide an overview as to what makes ceria nanoparticles merit attention in disease therapy. The introductory part describes the characteristics of ceria nanoparticles as an oxygen‐deficient metal oxide. The pathophysiological roles of ROS and RNS are then presented, as well as their scavenging mechanisms by ceria nanoparticles. Representative examples of recent ceria‐nanoparticle‐based therapeutics are summarized by categorization into organ and disease types, followed by the discussion on the remaining challenges and future research directions.

AbstractBiofilm formation is a major cause of hospital‐acquired infections. Research into biofilm‐resistant materials is therefore critical to reduce the frequency of these events. Polymer microarrays offer a high‐throughput approach to enable the efficient discovery of novel biofilm‐resistant polymers. Herein, bacterial attachment and surface chemistry are studied for a polymer microarray to improve the understanding of Pseudomonas aeruginosa biofilm formation on a diverse set of polymeric surfaces. The relationships between time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS) data and biofilm formation are analyzed using linear multivariate analysis (partial least squares [PLS] regression) and a nonlinear self‐organizing map (SOM). The SOM models revealed several combinations of fragment ions that are positively or negatively associated with bacterial biofilm formation, which are not identified by PLS. With these insights, a second PLS model is calculated, in which interactions between key fragments (identified by the SOM) are explicitly considered. Inclusion of these terms improved the PLS model performance and shows that, without such terms, certain key fragment ions correlated with bacterial attachment may not be identified. The chemical insights provided by the combination of PLS regression and SOM will be useful for the design of materials that support negligible pathogen attachment.

Published: February 2023

AbstractIn the under‐screen fingerprint recognition of smart cell phones, the tiny image signals are easily deteriorated by the protective membranes of screens. To solve this issue, an optical waveguide comprising two stage dual‐function gratings is proposed to supply extra lighting. The first stage is formed by two adjacent gratings possessing a cross angle of 120°, which serve as couplers and beam splitters to trap and split the incident light into two paths within the optical waveguide film, respectively. The second stage gratings, possessing a 60° included angle to the first stage, act as beam orientators and expanders by consecutively redirecting a portion of the light beams towards the sensing zone. By covering the waveguide film outside on an organic light emitting diode display screen and setting a camera and a laser under the screen, this slim construction shows high efficiency and large area under‐screen fingerprint recognition with high signal contrast. The design inspires a novel method for efficiently and flexibly controlling photons by arranging a series of gratings with the proper orientations and locations on a chip, which is highly demanded in displays and optical communication.

Published: February 2023

AbstractBioelectricity has been a fundamental property of all living organisms. With electrical stimulation, living cells can interact with their microenvironments, which makes electrical stimulation highly beneficial for various biomedical applications. However, traditional electrical stimulation mainly relies on bulky and complex equipment, which may not be ideal due to the restriction of movement, limited battery lifetime, uncomfortable wearing, and potential unfriendly to the environment. The advent of triboelectric nanogenerators (TENGs) has helped to resolve the existing limitations. TENGs are effective energy harvesting systems that use a mix of triboelectrification and electrostatic induction to create electrical energy from kinetic energy. TENGs deliver self‐powered electrical stimulation to bone cells for functional regulation or bone regeneration, serve as sensors to detect biological signals or movements, or act as a power source for other biomedical devices. TENGs can be employed in various applications, including enhancing bone regeneration, providing sensing function, slowing bone aging, and curing implant‐related infections. The recent applications of TENGs in bone tissue engineering are reviewed, and the drawbacks of the TENGs are discussed. Finally, the existing challenges and future roadmap for developing TENGs are presented.

AbstractGarnet‐type solid‐state electrolyte (SSE) Li6.5La3Zr1.5Ta0.5O12 attracts great interest due to its high ion conductivity and wide electrochemical window. But the huge interfacial resistance, Li dendrite growth, and low critical current density (CCD) block the practical applications. Herein, a superlithiophilic 3D burr‐microsphere (BM) interface layer composed of ionic conductor LiF‐LaF3 is constructed in situ to achieve a high‐rate and ultra‐stable solid‐state lithium metal battery. The 3D‐BM interface layer with a large specific surface area shows a superlithiophilicity and its contact angle with molten Li is only 7° enabling the facile infiltration of molten Li. The assembled symmetrical cell reaches one of the highest CCD (2.7 mA cm−2) at room temperature, an ultra‐low interface impedance of 3 Ω cm2, and a super‐long cycling stability of 12 000 h at 0.1–1.5 mA cm−2 without Li dendrite growth. The solid‐state full cells with 3D‐BM interface show outstanding cycling stability (LiFePO4: 85.4%@900 cycles@1 C; LiNi0.8Co0.1Mn0.1O2:89%@200 cycles@0.5 C) and a high rate capacity (LiFePO4:135.5mAh g−1 at 2 C). Moreover, the designed 3D‐BM interface is quite stable after 90 days of storage in the air. This study offers a facile strategy to address the critical interface issues and accelerate the practical application of garnet‐type SSE in high performance solid‐state lithium metal batteries.

AbstractDespite the promising advancements of in situ forming nanoassembly for the inhibition of tumor growth and metastasis, the lack of sufficient triggering sites and hardly controlling the forming position restrict their further developments. Herein, a smart transformable peptide‐conjugated probe (DMFA) with enzyme cleavage‐induced morphological change is designed for treatment on the tumor cell membrane. Specifically, after self‐assembling into nanoparticles and anchoring on the cell membrane with sufficient interaction sites rapidly and stably, DMFA will be efficiently cleaved into α‐helix forming part (DP) and β‐sheet forming part (LFA) by overexpressed matrix metalloproteinase‐2. Thus, the promoted Ca2+ influx by DP‐induced cell membrane breakage and decreased Na+/K+‐ATPase activity by LFA‐assembled nanofibers wrapping the cells can inhibit PI3K‐Akt signaling pathway, leading to the inhibition of tumor cell growth and metastasis. This peptide‐conjugated probe undergoes in situ morphological transformation on the cell membrane, exhibiting great potential in tumor therapy.
