Authors: Díaz-Campo Jesús , Segado-Boj Francisco , Fernández-Gómez Erika
Published: July 2021

User behavior patterns when consuming and sharing information on social networks are analyzed, paying special attention to the effects of the type of presentation and the type of social network. As is common when analyzing activity on social networks, we used the experience sampling method, in which a group of volunteer participants are asked, at different times, a set of questions about their recent activity or experience. The sample consisted of 279 subjects. The results show that news requiring a greater effort is usually shared through closed networks, while in open networks there is a tendency to share more superficial information. No significant differences are found between the degree of reading of the news and the type of social network where it is shared. Moreover, the level of consumption does not influence the degree of reading of the shared material. The level of enjoyment of the news is found to influence its degree of reading. The differences between networks highlight that, on Facebook, the frequency of use influences the dynamics of consumption and sharing, with shared news being more emotional and useful. In contrast, in the case of Twitter, there is a greater preference for so-called soft information.

Resumen
Se analizan los patrones de comportamiento que siguen los usuarios a la hora de consumir y difundir información en redes sociales, prestando especial atención a cómo influye el tipo de exposición y el tipo de red social. Se utilizó el método de muestreo de experiencias, de uso habitual para analizar la actividad en las redes sociales, que consiste en que un grupo de participantes voluntarios debe contestar, en distintos momentos temporales, a un conjunto de preguntas sobre alguna actividad que hayan realizado o alguna experiencia que hayan tenido. La muestra estuvo formada por 279 sujetos. Los resultados muestran que las noticias que requieren un mayor esfuerzo suelen compartirse en redes cerradas, mientras que en las redes abiertas se tiende a compartir información más superficial. No existen diferencias significativas entre el grado de lectura de la noticia y el tipo de red social donde se comparte; el nivel de consumo no influye en el grado de lectura de las que se comparten. Se ha comprobado que el nivel de disfrute de las noticias influye en su grado de lectura. Respecto a las diferencias entre redes, destaca el hecho de que en Facebook la frecuencia de uso influye en las dinámicas de consumo y difusión, y cómo las noticias compartidas tienen más afecto y utilidad. Por el contrario, en el caso de Twitter existe una mayor preferencia hacia las informaciones consideradas blandas.
A One-Year Audit of Varicose Vein Surgery at a Vascular Surgical Unit with a Long-Term Duplex and Quality of Life Follow-Up
Authors: Nelzén Olle , Nelzén Olle , Fransson Ingvor
Published: July 2021

Objective: With the introduction of endovenous treatments, open varicose veins surgery was discarded due to a claimed high risk of neovascularisation. A one-year audit was set up to look at results from performing mainly open surgery.
Methods: All varicose vein interventions were registered and prospectively followed with colour Duplex assessments after 4-6 weeks, 1 and >5 years. In addition, Aberdeen Varicose Vein Questionnaire (AVVQ) was used in addition to Varicose Vein Severity Score (VCSS) to assess patients’ quality of life (QoL) and the disease severity.
Results: During the year, 236 patients/252 legs were operated and 28% were re-do procedures. Median age was 55 years (16-87) and 70% were females. Duplex at 4-6 weeks showed a primary success rate of 91%. Neovascularisation was noted in 8% one year after primary surgery. The long-term assessment was done after a median of 69 months (39-75) and 67% of all legs were examined. After primary surgery 16% showed neovascularisation compared with and 27% after re-do procedures. VCSS improved significantly from 6 (range 1-22) to 2 at the long-term follow-up (p<0.001). The AVVQ score improved from 20 (range 3-55) down to 10 (p<0.001).
Conclusion: The risk for neovascularisation seems to have been overestimated and good long-term results can be achieved following modern open surgery. The major problem is to avoid varicose vein recurrence since results from re-do procedures seem less favourable long term.

COINTEGRATING THE LONG-RUN RELATIONSHIP OF ECONOMIC VARIABLES
Authors: Duguleana Constantin
Published: July 2021

"The economic non-stationary time series often have long-run
relationships. The cointegration relationship of time variables describes the
continuous adaptation to their equilibrium in the long-run. This paper
presents the ways of analysing and modelling the cointegration of time
series. The Error Correction Model, as a main tool, and the Engle-Granger
method are used to estimate the cointegration in the case of the long-run
relationship between the quarterly GDP and the Final Consumption in
Romania during the period 1995 – 2019. The practical importance of
applying the cointegrating model consists in knowing the effect of GDP in the
long term. "

BACKGROUND: Despite the dominance of implant-based breast reconstruction after mastectomy, during recent years, it has been correlated to some complications. The aim of this study is to present the Greek experience about management of implant infections after breast reconstructions and to investigate the relationship between possible risk factors and breast pocket fluid cultures. METHODS: In total, 260 patients underwent implant-based breast reconstruction due to breast cancer in our center from 2016 until 2020. 46 patients, that underwent implant or expander replacement after breast reconstruction due to mastectomy were included in the present study. RESULTS: 260 patients underwent breast reconstruction in our center and in 46 (18%) of them an implant replacement was required. 21 patients (8%) presented clinically with an implant infection, but 12 of them (5%) had positive cultures from the breast pocket fluid. On the contrary, 25 patients (10%) presented no clinical signs of implant infection, but 5 of them (2%) had a positive culture. In addition, we demonstrated a correlation between implant infection and positive cultures (p = 0.009), along with an association between chemotherapy before implant placements and negative cultures (p = 0.035). Finally, the most common pathogen was Staphylococcus epidermidis (29%), followed by Escherichia coli (24%) and Staphylococcus aureus (18%). CONCLUSION: Implant infection still remains a very serious complication after breast reconstruction surgery. The establishment of a therapeutic protocol, with specific antimicrobial and surgical targets seems as an effective strategy against implant infections.

Published: July 2021

BACKGROUND: Allogeneic hematopoietic stem cell transplantation (ASCT) is the preferred treatment option for patients with several hematologic disorders and immunodeficiency syndromes. Graft-versus-host disease (GVHD) is an immune mediated post-transplant complication which has a major impact on long-term transplant outcomes. OBJECTIVE: Current efforts are focused on identification of new markers that serve as potential predictors of GVHD and other post-transplant clinical outcomes. METHODS: This study includes donor harvests collected from twenty-three allogeneic donors during period 2008–2009 and respective transplant recipients followed for clinical outcomes till March 2019. Percent CD26+ and CD34+ cells in donor harvest were analyzed using flow cytometry. Percent expression and infused dose of CD26+ and CD34+ cells were evaluated for association with various clinical outcomes. RESULTS: Total 23 healthy donors with median age of 28 years (13 males), and transplant recipients with median age of 24 years (17 males) formed the study cohort. The diagnosis included malignant (n= 13) and non-malignant (n= 10) hematological disorders. Median CD34brCD45lo HSC expression was 0.57% (IQR 0.24–1.03) while median CD26 expression was 19.64% (IQR 8.96–33.56) of all nucleated cells. CD26 expression was associated with donor age (P= 0.037). CD26 percent expression correlated with WBC engraftment (P= 0.015) and with acute GVHD (P= 0.023) whereas infused CD26 cell dose correlated with WBC engraftment (P= 0.004) and risk of CMV reactivation (P= 0.020). There was no statistically significant correlation of either CD26 expression or cell dose with chronic GVHD, EFS or OS. CONCLUSIONS: Our findings suggest a role of CD26 expression on human donor harvest as a potential predictor of acute GVHD. This association warrants further exploration.

Published: July 2021

Background: Alzheimer’s disease (AD) is one of the most challenging diseases causing an increasing burden worldwide. Although the neuropathologic diagnosis of AD has been established for many years, the metabolic changes in neuropathologic diagnosed AD samples have not been fully investigated. Objective: To elucidate the potential metabolism dysregulation in the postmortem human brain samples assessed by AD related pathological examination. Methods: We performed untargeted and targeted metabolomics in 44 postmortem human brain tissues. The metabolic differences in the hippocampus between AD group and control (NC) group were compared. Results: The results show that a pervasive metabolic dysregulation including phenylalanine metabolism, valine, leucine, and isoleucine biosynthesis, biotin metabolism, and purine metabolism are associated with AD pathology. Targeted metabolomics reveal that phenylalanine, phenylpyruvic acid, and N-acetyl-L-phenylalanine are upregulated in AD samples. In addition, the enzyme IL-4I1 catalyzing transformation from phenylalanine to phenylpyruvic acid is also upregulated in AD samples. Conclusion: There is a pervasive metabolic dysregulation in hippocampus with AD-related pathological changes. Our study suggests that the dysregulation of phenylalanine metabolism in hippocampus may be an important pathogenesis for AD pathology formation.
Fault-tolerant model predictive control of six-phase permanent magnet synchronous hub motors
Authors: Sun Xiaodong , Cai Feng , Tian Xiang , Wu Minkai
Published: July 2021

Permanent magnet synchronous hub motors (PMSHMs) have been gradually introduced into the applications of electric vehicles. On this basis, the six-phase motor has the characteristics of high reliability, high power density and low torque ripple. And its fault tolerance is a large advantage compared with the three-phase motor. The multi-phase permanent magnet synchronous motor is redundant due to the number of phases. When the motor fails, it does not have to stop running, merely adjust its control mode and enter the fault-tolerant compensation control algorithm to resume the operation of the system. The FCS-MPC algorithm can replace the cascade structure in the traditional control and eliminate the modulation module. This makes it have good steady-state performance. The speed response is also improved. It can be combined with multiple control objectives with strong flexibility by simply changing the objective function. The prediction model is compensated. Finally, the experimental results show the effectiveness of this method.

Authors: Schutz Michele A. , Carter Erik W. , Maves Erin A. , Gajjar Shimul A. , McMillan Elise D.
Published: July 2021

BACKGROUND: Effective school partnerships are crucial for supporting transition-age youth with disabilities to transition to adulthood. Although the importance of strong school-community collaboration is widely advocated, many school districts still struggle to establish transition partnerships within and beyond the school. OBJECTIVE: This study examined the application of “community conversation” events as a pathway for convening local communities to reflect on and strengthen their existing transition partnerships. METHODS: Five school districts held events that engaged a total of 213 local citizens in constructive dialogue about enhancing school-employer-community partnerships. RESULTS: Collectively, the individuals involved in these community conversations generated 55 distinct recommendations for developing or deepening transition partnerships, both within and beyond the walls of their local schools. When asked about the strength of current transition partnerships, however, the views of attendees were quite mixed. CONCLUSIONS: We offer recommendations for research, practice, and policy aimed at strengthening partnerships among schools, employers, agencies, families, and communities that improve the preparation and outcomes of youth with disabilities.
Vocational identity of veterans with co-occurring mental health and substance use disorders
Authors: Stevenson Brian J. , Thrower Stephanie J. , Mueller Lisa , Kelly Megan M.
Published: July 2021

BACKGROUND: No studies have examined vocational identity among individuals with co-occurring mental health and substance use disorders. OBJECTIVE: Influenced by Blustein’s relational theory of working (2011), this study examined the relationships between several social-environmental variables (external/relational conflicts, employment barriers, substance abuse stigma) and vocational identity. METHODS: Eighty-four veterans receiving treatment from the Veterans Health Administration (VHA) for co-occurring mental health and substance use disorders participated in this survey study. RESULTS: Education, employment, clinical, disability, and substance abuse factors were not associated with vocational identity, but external/relational conflicts, employment barriers, and substance abuse stigma were. Multiple regression analysis found that these variables accounted for 34%of the variance in vocational identity and that external/relational conflicts was the only significant predictor. CONCLUSIONS: Findings suggest that more conflictual messages about work from external/relational sources is related to less clarity around one’s vocational interests, goals, and talents.
Exploring the role of professional development on secondary special educators self-efficacy and use of evidence-based transition practices
Authors: Bruno Lauren P. , Scott LaRon A. , Thoma Colleen A.
Published: July 2021

BACKGROUND: Past research has suggested that secondary special educators enter the profession with limited knowledge and skills to provide effective evidence-based transition practices (EBTPs) to students with disabilities. Professional development (PD) is known to be one pathway to expand teachers’ knowledge and delivery of evidence-based transition practices, yet minimal research exists investigating what PD activities are most effective at increasing teachers’ use of EBTPs. OBJECTIVE: The purpose of this study was to determine how transition specific PD influenced secondary special educators’ knowledge and perceived self-efficacy regarding the use of EBTPs in their classrooms to support students with disabilities. METHODS: A correlational research design was used to investigate teacher self-efficacy to deliver EBTPs when the amount, type, and location of PD are factors. Descriptive statistics, an analysis of variance (ANOVA), and a multiple linear regression analysis were performed. RESULTS: The amount of PD offered had a significant effect on teachers’ perceived efficacy compared to the location and type of professional development received. Further, the results of teachers’ perceived effectiveness, changes made as a result of PD, and other factors related to PD are reported. CONCLUSIONS: After receiving PD, teachers were more likely to make changes in their classroom that, in turn, affected their self-efficacy and effectiveness to deliver EBTPs to support students with disabilities. Implications for teacher professional development research, practice, and policy are also discussed.

Authors: Young Illies Marcy , Valentini Brian J. , Ingles Kristina E. , Gilson Carly B.
Published: July 2021

BACKGROUND: WIOA encourages providers such as Vocational Rehabilitation (VR) to seek higher wages and more than part-time hours for those with disabilities. Previous studies have evaluated the relationship between (VR) and job outcomes for individuals with intellectual disability (ID). OBJECTIVE: The present study evaluated the effect of VR services on wage and hours worked. METHOD: We obtained a national dataset from the Rehabilitation Services Administration to analyze individuals with ID on variables specially related to training and VR services. RESULTS: Results indicated more training resulted in more hours worked, while using more VR services resulted in less hours worked and pay. Differences in hours worked and wage were found within training and VR services. CONCLUSION: Individuals with ID should consider utilizing job counseling with VR agencies and focus on occupational training, as these services may contribute to increased wages and hours worked.

Published: July 2021

BACKGROUND: Telerehabilitation is an effective health delivery method for patients with a variety of health conditions. There is insufficient knowledge about use of telerehabilitation to support patients with disabilities and chronic illness in obtaining or sustaining competitive employment. Employment rates of Veterans are lower than civilian rates, and the employment gap is higher for Veterans living in rural areas. OBJECTIVE: To investigate factors that enabled and constrained routine use of video tele-technologies in delivering individualized community-based vocational rehabilitation (referred to as Tele-VR) services and to identify impacts and promising practices in implementation. METHODS: Semi-structured interviews with providers from two Veterans Health Administration Medical Sites that use telerehabilitation to supplement their existing face-to-face individualized community-based VR services. Interviews were analyzed using thematic analysis. RESULTS: Five themes in the implementation of Tele-VR were identified (1) Enhancing Workflow for Providers, (2) Improving Quality of Therapeutic Care, (3) Practicalities in Implementing Tele-VR, (4) Embedding Vocational Rehabilitation into Interdisciplinary Care as a Facilitator to Implementation, and (5) Impact of Tele-VR. CONCLUSIONS: The telerehabilitation delivery of employment service to Veterans with disabilities is a viable means for remotely providing or enhancing face-to-face individualized and community-based VR services that support Veterans’ competitive employment and job stability within their communities.
Correlation based malicious traffic analysis system
Authors: Arivudainambi D. , Varun Kumar K.A. , Satapathy Suresh Chandra
Published: July 2021

Artificial intelligence methods have often been applied to carry out specific functions or errands in the cyber-defense realm. However, as adversary methods become more complex and difficult to divine, piecemeal efforts to understand cyber-attacks, and malware-based attacks in particular, are not providing sufficient means for malware analysts to understand the past, present and future distinctiveness of malware. Because, most of the malware communications take place-utilizing services. These services are completely anonymous and monitoring such services is a hard task. To address this issue, this paper proposes a novel traffic analysis scheme using correlation methods (non-parametric approach). Experiments are performed to validate the proposed approach on the real time traffic data collected over the period of 1 week. The experimental results confirm that the proposed method outperforms the existing state of the art traffic analysis schemes. The result also exhibits the traffic classification performance, which is analyzed by the decade old nearest neighbor method.

Authors: Singh Amrik , Ramkumar K.R.
Published: July 2021

Due to the advancement of medical sensor technologies new vectors can be added to the health insurance packages. Such medical sensors can help the health as well as the insurance sector to construct mathematical risk equation models with parameters that can map the real-life risk conditions. In this paper parameter analysis in terms of medical relevancy as well in terms of correlation has been done. Considering it as ‘inverse problem’ the mathematical relationship has been found and are tested against the ground truth between the risk indicators. The pairwise correlation analysis gives a stable mathematical equation model can be used for health risk analysis. The equation gives coefficient values from which classification regarding health insurance risk can be derived and quantified. The Logistic Regression equation model gives the maximum accuracy (86.32%) among the Ridge Bayesian and Ordinary Least Square algorithms. Machine learning algorithm based risk analysis approach was formulated and the series of experiments show that K-Nearest Neighbor classifier has the highest accuracy of 93.21% to do risk classification.

Authors: Jaffe Ashlee , Powell Maura , Konieczny Tami , Osweiler Carlene , Kreher Genna
Published: July 2021

PURPOSE: The WeeFIM is a tool commonly used in pediatric rehabilitation settings to measure objective patient progress while receiving comprehensive therapy services on inpatient rehabilitation units. This Quality Improvement (QI) project aimed for 95% of inpatients to have complete, on-time documented and displayed WeeFIM scores upon admission and discharge by 12/2017. METHODS: An interdisciplinary team examined historic WeeFIM completion rates. Using Plan-Do-Study-Act cycles, a unified flowsheet was developed in the electronic health record (EHR) to revamp workflow and identify opportunities for improvement, data accuracy, and finally sustainability. Progress was monitored in real time via an automated data visualization tool which monitored score timeliness and completeness. RESULTS: On-time admission completion rates increased from 0% to 95% during the intervention period. On-time discharge completion rates increased from 0% to 89% during the intervention period. This change has been sustained over two years with on-time admission and discharge scores averaging 79.4% and 77.9% respectively, and 96.4% of scores completed. CONCLUSION: Changes in the completion rate of WeeFIMs are sustainable, evidenced by ongoing maintenance of our initial gains over the course of multiple months. The incorporation of WeeFIM documentation into the workflow increased on-time and overall completion rates. The success of this project shows that integrating new tasks into provider workflows helps drive completion.

Published: July 2021

Introduction: In this systematic review, we will discuss the change of stroke incidence during the COVID-19 pandemic period and the proposed mechanisms of the relationship between SARS-CoV-2 and stroke. Methods: Web of Science, PMC/Medline, and Scopus databases were searched until July 2020 without time and language limitations. After quality assessment, 22 articles were included in this study. Results: Based on the results, it is impossible to conclude any definite relationship between the rising or decreasing stroke frequency or the shift in the ischemic and hemorrhagic ratio and SARS-CoV-2 infection. However, it appears that SARS-CoV-2 infection has some correlation with stroke. The supposed mechanisms for the SARS-CoV-2-related hemorrhagic stroke include 1) SARS-CoV-2-related vasculopathy with the endothelial damage of small vessels, 2) viral infection-induced platelet dysfunction or thrombocytopenia, and 3) activation of the proinflammatory cascade leading to coagulopathy. The helpful strategies are receiving therapeutic anticoagulation for high D-dimer or a known thrombus due to SARS-CoV-2 infection, as well as using extracorporeal membrane oxygenation (ECMO) in some patients. Furthermore, the possible mechanisms for the SARS-CoV-2-related ischemic stroke include 1) dysregulation of angiotensin-converting enzyme 2 (a key host cellular receptor for SARS-CoV-2)-related physiologic functions, 2) endothelial cell damages, 3) thrombo-inflammation, and 4) coagulopathy and coagulation abnormalities related to SARS-CoV-2 infection. Conclusion: A better understanding of the SARS-CoV-2 pathogenesis and its relation to neurologic abnormalities such as stroke can help to design new therapeutic approaches.
Estudo De Caso: Modelagem E Verificação De Interferências Entre As Disciplinas De Um Edifício Utilizando A Metodologia Bim

Com o passar dos anos, os projetos de construção civil começaram a aumentar sua complexidade e a metodologia tradicional, que se baseia em documentação 2D, não está suprindo de forma eficiente as demandas de mercado. As disciplinas de projetos, estão cada vez mais sendo designadas a equipes distintas, ocorrendo o aumento de interferências de projetos, que geram atrasos, retrabalhos e custos além do previsto. O processo mais comum de verificação destas interferências é através da sobreposição das plantas em 2D, porém, além de desgastante, este processo ignora alguns erros que só apareceriam em vistas tridimensionais. Este trabalho teve como objetivo a aplicação dos conceitos da metodologia BIM (Building Information Modeling) em um estudo de caso que visou a modelagem e análise de interferências dos projetos arquitetônico, estrutural, hidrossanitário e elétrico de uma edificação mista residencial multifamiliar e comercial. Para tanto, foi realizada a modelagem tridimensional a partir dos projetos já finalizados em CAD 2D, modelando-os no software Autodesk Revit® e os associando através do software Autodesk Navisworks®. A partir da modelagem e as 9 associações realizadas na compatibilização, foi possível obter um total de 162 interferências, que foram detectadas na fase de projeto e que seriam constatadas, provavelmente, apenas na fase de execução. É possível admitir que a associação mais problemática encontrada neste trabalho foi a relação entre as disciplinas de estrutura e de instalações hidrossanitárias, com 42,60% das interferências.
La Pandemia COVID-19: desafío al discurso de desarrollo bajo el modelo económico neoliberal
Authors: Urquizú Solís Alhelí Fabiola
Published: July 2021

El modelo capitalista neoliberal que rige el mundo en el siglo XXI, no puede negar la alarmante situación de muertes por COVID-19, así como tampoco su incapacidad para responder ante el impacto económico que está generando dicha pandemia. No tener el control hasta estos momentos de lo primero pone fuera de sus manos el control de lo segundo. La dinámica de libre mercado queda restringida ante epidemias mundiales o crisis ambientales de alto nivel. El desarrollo pensado desde “arriba” no alcanza a explicar las consecuencias que el fenómeno de crisis sanitaria mundial está ocasionando a nivel económico, social y político. El post-desarrollo empieza a tener sentido, al cuestionar el concepto de crecimiento económico y sus metas, pugnando por incluir una cosmovisión como fundamento de un nuevo modelo de desarrollo a nivel mundial. Este trabajo tiene como propósito evidenciar la necesidad de incluir nuevas formas de desarrollo que contemplen múltiples universos.
Extractivismos agropecuarios en tiempos de pandemia: flexibilizaciones, asimetrías, autoritarismos y otros efectos derrame
Authors: Artacker Tamara , Campanini Jorge , Gudynas Eduardo
Published: July 2021

En el contexto de la pandemia por Covid19, los gobiernos de América del Sur han mantenido los extractivismos agropecuarios (agrícolas, ganaderos y forestales). En unos casos se los presenta como solución a la caída de extractivismos en petróleo y minerales. En otros casos ocurren cambios entre distintos productos agropecuarios. Esta estrategia implica la persistencia de impactos sociales y ambientales, y acentúan las asimetrías entre actores empresariales y agricultores pequeños o campesinos. A pesar que en la crisis por la pandemia permitía promover una agricultura como proveedora de alimentos para atacar el componente nutricional entre los sectores más pobres, persistió la postura de concebirla como proveedora de mercancías de exportación, acentuándose los extractivismos. Se mantuvieron y en algunos casos se profundizaron los efectos derrame, tales como flexibilizaciones sociales, laborales y ambientales, y se fortalecieron políticas públicas que sostienen y blindan a los extractivismos.
Pedagogía desde el des-borde
Authors: Mazzino Ana
Published: July 2021

El presente artículo pretende abrir un diálogo a partir de las reflexiones e interrogantes suscitados a raíz la pandemia COVID-19 y del valor innegable que lo educativo tiene en nuestras sociedades. La propuesta es movernos, a lo largo y ancho de un eje-espacio temporal que oscila entre aquello que arrastramos como gestos fundantes del sistema educativo y lo que podemos reconvertir en oportunidad si tenemos el coraje de (re)abrir la pregunta sobre el sentido de lo educativo.
Enseñar y aprender en la no presencialidad: percepciones de estudiantes de posgrado-docentes
Authors: Cariaga Romina
Published: July 2021

Este trabajo tiene por objetivo hacer un análisis contextualizado de los relatos de experiencia manifiestos en un foro sobre las prácticas educativas en modalidad no presencial durante la pandemia de docentes-estudiantes de posgrado.  Se apoya en herramientas de la investigación cualitativa interpretativa y propone un análisis de los relatos desde dos dimensiones: dificultades encontradas y cambios implementados. Los resultados muestran que si bien los recursos tecnológicos adoptados en este contexto excepcional no reemplazan la potencialidad de los vínculos ni los métodos de la presencialidad se constituyen en recursos necesarios y enriquecedores de todas las propuestas áulicas. Asimismo, se concluye que es necesario pensar en nuevas formas de escolaridad, híbridas, donde lo virtual y lo real coexistan y donde las instituciones procuren la formación de sujetos con capacidades para desenvolverse en entornos cambiantes, dispuestos a aprender de otros y con otros a través de una adopción crítica de la tecnológica.

Spatio-temporal variability in the deposition of beach-cast kelp (wrack) and inter-specific differences in degradation rates
Authors: Gilson AR , Smale DA , Burrows MT , O’Connor NE
Published: July 2021

Coastal habitats dominated by marine macroalgae typically exhibit high rates of primary productivity and play a key role in local and regional carbon cycles and stores. In temperate regions, large brown algae (i.e. kelps and fucoids) contribute significantly to macroalgal primary production, most of which is exported from source habitats as detritus. The ultimate fate of this detritus and the processes controlling detrital pathways into food webs and carbon cycles remain poorly understood. Based on field surveys, we quantified the biomass of kelp-derived detritus (wrack) at sandy and pebble-dominated shores in Ireland and conducted a manipulative field experiment to test for inter-specific differences in detritus degradation rates and the effect of macroinvertebrate detritivores. Overall, accumulated wrack biomass was similar on all shores but varied temporally depending on habitat type. Degradation rates and the nutritional (C:N) and chemical (polyphenol concentrations) properties differed among kelp species. Interestingly, exclusion of macroinvertebrate detritivores did not affect kelp degradation rates, C:N ratios or polyphenol content. Our findings show that rates of macroalgal breakdown differ among kelp species and that, in contrast to other aquatic systems, macroinvertebrates appear to play a very limited role in the breakdown of these marine detrital subsidies, suggesting a key role for meiofauna and microbes in detritus processing. Increasing recognition for the role of detritus in coastal food webs and carbon cycles warrants a better understanding of the mechanisms underpinning degradation rates.
Glucose-Fatty Acid Interaction in Skeletal Muscle and Adipose Tissue in Insulin Resistance
Authors: Cahová M , Vavřínková H , Kazdová L
Published: July 2021

Insulin resistance (IR) is the result of long-lasting positive energy balance and the imbalance between the uptake of energy rich substrates (glucose, lipids) and energy output. The defects in the metabolism of glucose in IR and type 2 diabetes are closely associated with the disturbances in the metabolism of lipids. In this review, we have summarized the evidence indicating that one of the important mechanisms underlying the development of IR is the impaired ability of skeletal muscle to oxidize fatty acids as a consequence of elevated glucose oxidation in the situation of hyperglycemia and hyperinsulinemia and the impaired ability to switch easily between glucose and fat oxidation in response to homeostatic signals. The decreased fat oxidation results into the accumulation of intermediates of fatty acid metabolism that are supposed to interfere with the insulin signaling cascade and in consequence negatively influence the glucose utilization. Pathologically elevated fatty acid concentration in serum is now accepted as an important risk factor leading to IR. Adipose tissue plays a crucial role in the regulation of fatty acid homeostasis. The adipose tissue may be the primary site where the early metabolic disturbances leading to the development of IR take place and the development of IR in other tissues follows. In this review we present recent evidence of mutual interaction between skeletal muscle and adipose tissue in the establishment of IR and type 2 diabetes.
