Proyecto de intervención para la capacitación virtual de profesores de educación superior en diseño instruccional y recursos educativos digitales

La pandemia generada por la covid-19 ha tenido un impacto negativo en los ámbitos económicos, sociales y educativos. La contingencia ha obligado a que más personas, sin importar su profesión o actividad, recurran a plataformas digitales para prepararse en el aspecto profesional y académico. Este artículo, por tanto, tiene como objetivo presentar los resultados de un trabajo de investigación evaluativa llevado a cabo para medir la implementación del proyecto de intervención sobre la capacitación de profesores de educación superior en el diseño instruccional y en la producción de recursos educativos digitales. Para evaluar el proyecto, se elaboró un instrumento, el cual se aplicó en línea luego de la capacitación para identificar los resultados descriptivos e inferenciales. Para la obtención de los datos y su análisis respectivo, se aplicó una metodología de corte mixto que consideró diferentes momentos, actores e instrumentos. En concreto, se aplicó un enfoque cuantitativo. La investigación se llevó a cabo en la Universidad Veracruzana, específicamente con la participación de profesores del área académica técnica. Los resultados señalan que el proyecto de intervención tuvo resultados favorables en cuanto al diseño de cursos en línea bajo una metodología de diseño instruccional con el uso de recursos educativos digitales, pues se incrementó la acreditación en las materias de la modalidad mixta; sin embargo, es necesario realizar otro estudio que contraponga las percepciones de los profesores y de los estudiantes sobre la mejora en los procesos de enseñanza-aprendizaje.
The HROC-Xenobank—A High Quality Assured PDX Biobank of >100 Individual Colorectal Cancer Models

Simple Summary Considering recent research, it was established that the best experimental models to conserve biological features of human tumors and to predict individual clinical treatment success are patient-derived xenografts (PDX). Their recognized and growing importance for translational research, especially for late-stage preclinical testing of novel therapeutics, necessitates a high number of well-defined PDX models from individual patients’ tumors. The starting platform for the Hansestadt Rostock colorectal cancer (HROC)-Xenobank was the assortment of colorectal tumor and normal tissue samples from patients stored in our university biobank. Abstract Based on our research group’s large biobank of colorectal cancers (CRC), we here describe the ongoing activity of establishing a high quality assured PDX biobank for more than 100 individual CRC cases. This includes sufficient numbers of vitally frozen (n > 30 aliquots) and snap frozen (n > 5) backups, “ready to use”. Additionally, PDX tumor pieces were paraffin embedded. At the current time, we have completed 125 cases. This resource allows histopathological examinations, molecular characterizations, and gene expression analysis. Due to its size, different issues of interest can be addressed. Most importantly, the application of low-passage, cryopreserved, and well-characterized PDX for in vivo studies guarantees the reliability of results due to the largely preserved tumor microenvironment. All cases described were molecularly subtyped and genetic identity, in comparison to the original tumor tissue, was confirmed by fingerprint analysis. The latter excludes ambiguity errors between the PDX and the original patient tumor. A cancer hot spot mutation analysis was performed for n = 113 of the 125 cases entities. All relevant CRC molecular subtypes identified so far are represented in the Hansestadt Rostock CRC (HROC)-Xenobank. Notably, all models are available for cooperative research approaches.
Introducing Emerging Technologies in the Curriculum through a Multidisciplinary Research Experience.

This paper describes Rowan University’s novel approach to integrating emerging technologies into the chemical engineering curriculum. Through an eight-semester project-based course sequence, every engineering student works in multidisciplinary on a series of projects, many of which are sponsored by regional industries. In addition to providing a mechanism to introduce emerging technologies, the clinics provide the students with experience in working in multidisciplinary teams, exposure to industrial projects with real deadlines and deliverables and an opportunity to develop their oral and written communication skills. Several brief case studies of clinic projects are also discussed.
The role of recreation in rehabilitation: a systematic review

Abstract. Study of the role and impact of recreational practices during the period of physical rehabilitation through a systematic analysis of modern approaches, such as: recreational therapy and the method of therapeutic recreation. Objective. The study of theoretical approaches to the definition of the terms "leisure" and "recreation" became the basis of this study. Methods. Critical analysis of modern scientific literature and systematic review of previous empirical research. Results. The conducted complex theoretical research allowed to formulate the following definitions: "leisure" – free time from work and related responsibilities, which a person decides to spend based on their own preferences, emotional state and mood; "recreation" – physical activity of people aimed at improving health, well-being, positive emotions and pleasure, relief from stress, as well as social interactions. In addition, the role of recreation in the rehabilitation process was studied, namely through the use of recreational therapy, which has a positive effect on health, rehabilitation effectiveness and well-being, which is achieved by receiving positive emotions from leisure, entertainment and social interactions. The therapeutic and recreational approach demonstrates the positive impact of physical and emotional activities (leisure) on the effectiveness of rehabilitation, recovery and return of people with injuries, illnesses or disabilities to normal activity, and also promotes a more active lifestyle.
Software Fault Detection Using Dynamic Instrumentation

In recent decades, microprocessor performance has been increasing exponentially. A large fraction of this performance gain is directly due to smaller and faster transistors enabled by improved fabrication technology. While such transistors yield performance enhancements, their lower threshold voltages and tighter noise margins make them less reliable [1], rendering processors that use them more susceptible to transient faults . Transient faults, also known as soft errors , are intermittent faults caused by external events, such as energetic particles striking the chip, that do not cause permanent damage but may result in incorrect program execution by altering signal transfers or stored values.

Schmidt, P. (2005). Music education as transformative practice: Creating new frameworks for learning music through a Freirian perspective Visions

The educational perspectives presented by Paulo Freire have been thoroughly analyzed and linked to the general education of children in urban America. Additional studies have focused on Freire’s pedagogy in higher education. Nevertheless, the number of studies that have examined music education and the pedagogy of music teaching and learning as a kind of pedagogy of emancipation are far more restricted, have become available only recently and are still not widely dispersed or read. In this article, Freirian concepts serve to develop frameworks that define the philosophy of a Critical Pedagogy for Music Education. This new conception borrows from Freire’s texts, and delineates practices believing that real learning to take place only if students and teachers alike are changed in and by the process of education.
High Isolation and Compact Microstrip Diplexer for Broadband and WLAN Application

A high isolation and compact microstrip diplexer for broadband and wireless local area network (WLAN) application is proposed in this paper. It is achieved by using the combination of a broadband bandpass filter (BPF) composed of one open stub and two short stubs of different size loaded in 50Ω feed lines. The tapped stub can not only generate two zeros to deepen the stopband, but also connect other BPF without deterioration of in-band performance. Hence, the compact diplexer combines two BPFs without extra junction matching network. The mutual loading effect approximately equivalent to a coupled resonator can create one zero at the passband edge to improve the isolation. The proposed microstrip diplexer is designed and fabricated, and it has a 1dB fractional bandwidths (FBW) of 60% at 3.5GHz for broadband channel and 3% at 5.8GHz for WLAN channel . The simulated and measured results are presented and good agreement is obtained.
Does Social Media Expand the Traditional Role of Chinese TV Journalists as Gatekeeper on Weibo and WeChat J-accounts

This study investigates how TV journalists negotiate their “gatekeeping” on ‘output’ stage and showcase various facettes of roles during the gatekeeping process on Weibo and WeChat personal accounts (J-accounts). Based on a semi-structured interviews with journalists, we show the different uses of Weibo and WeChat, which are useful tools for journalists to share information, search news resources and check facts when conducting the journalistic gatekeeping. TV journalists – as “gatekeepers” – are unwilling to allow audiences to participate in news delivering on ‘output’ stage. TV journalists’ different performances on J-accounts show that they act as news spreaders, news gatherers and verifiers, which is coherent with the task of “gatekeeping” on TV. Journalists also perform as information explainers and rumor refuters, these tasks are beyond traditional “gatekeeping” on TV. Journalists adapt their use of social media to fit traditional professional norms as well as adapting those norms to fit the media logic of the social media platform. This research initially combines content analysis with interview to examine and compare different journalistic practice regarding various uses of Weibo and WeChat and reflects comprehensively facettes of journalistic roles during gatekeeping. It contributes to the empirical analysis of various aspects of ‘gatekeeping practices’ in China.
WRITING AND WORKING IN THE BORDERLANDS : The Implications of Anzaldúan Thought for Chicana Feminist Sociology Elisa

I’m on a plane returning to Denver, Colorado, after creating community at a highly emotional gathering of women and men at the University of Texas, San Antonio, to celebrate the twenty-year anniversary of Gloria E. Anzaldúa’s Borderlands/La Frontera. I feel invigorated and inspired from the communal energies and exhausted by Anzaldúa’s challenge of fleshing our realities. My carry-on bag holds three of Anzaldúa’s books and seventeen pages of typed and handwritten notes. What a privilege to be living in the imaginary of Gloria E. Anzaldúa.
Backstepping Control Design on the Dynamics of the Omni-Directional Mobile Robot

The dynamical model of an omni-directional mobile robot is bulit based on the Newtonian mechanics. Correspondingly, a backstepping-based controller is then proposed with proven global stability by selecting a Lyapunov function and introducing a virtual control input for the built dynamical model. Simulation results show the effectiveness of the proposed controller.
Mathematical modeling of PMSG-based wind power plants (WPPs) for harmonic resonance studies and analytical assessment of wind turbines converters controls on WPP harmonic resonance response

In this paper harmonic resonance analysis of the grid comprising wind power plants (WPPs) with permanent magnet synchronous generators (PMSGs) is presented. Usually, Norton equivalent circuit is used as the wind turbine (WT) model for harmonic resonance studies, in which, WTs are simply modeled as ideal current and voltage sources and impacts of converters controls on the WTs output impedances are neglected. This paper deals with the harmonic resonance analysis of study WPP system taking the impacts of converters controls, and current and voltage measurement filters into account. In this way, harmonic impedance models of the WTs are presented for simple and detailed cases, and then WT harmonic impedance is extracted for the mentioned cases. Next, results of frequency scan and harmonic mode resonance analyses for different cases are given and compared, and then effects of the current and voltage measurements filters and WT converter control on harmonic resonance analysis of the study WPP system are presented. It is shown that increasing the bandwidth of the grid-side converter current control loop can not shift the resonant frequencies, but enhances the system damping, and consequently reduces the driving point impedances in the resonant frequencies.
Using Institutional Theory to Improve Results in an Industrial Company

The current world is more and more globalized, with the competence level enhancing day by day and the enterprises having to be prepared to give positive answers to the questions proposed to them. Being prepared to face different kinds of situations is the biggest challenge of their leaders. An action taken in any part of the world will bring enormous consequences in a short period of time. The velocity in which information comes and the way it is analysed and processed will separate the survivors from the losers. Changes happen continuously, demanding of the enterprise frequent revaluations of the trends of the market and its positioning. The alternatives are many and imprecise towards an obviously uncertain future. The more knowledge an enterprise has about the competitiveness determining factors, the higher is its possibility of being right. It is necessary to interpret those factors to participate of the rival environment in favourable conditions, which means filtering all those information, focusing on the ones that really have impact on your business. The importance and relevance of the theme “Results Improvement” are related to the reality of the industrial enterprises and their difficulty on keeping themselves competitive in a globalized environment. This theme will reinforce that the option for the institutionalization of result methodologies can be a profitable way to the enhancement of the competitiveness of those industrial organizations. Our intention is to demonstrate that together with a politics of collaborators’ participation in the process of work, the institutionalization of methodologies focused on results can explain why some organizations survive and others fail or have to link themselves to others. This association of variables described below, can be determining for the enterprise success, as we live in the era of knowledge, of the information velocity, of the details … and the ones who can better associate those variables will have a competitive advantage in relation to the other players.
Simplified R-Factor Relationships for Strong Ground Motions

Recent studies have demonstrated the need to consider the ground motion frequency content in the development and use of R−μ−T relationships. Results from two different approaches to determining these relationships are unified in the present paper. Two bilinear R−μ−T/Tg relationships are recommended for most strong ground motions and structural systems. One is more accurate, while the other, more conservative relationship is used in FEMA 273, ATC-32, and the simple version of the N2 method. Both relationships are indexed by the characteristic period of the ground motion, Tg. Simple methods to determine Tg from smoothed design spectra and recorded ground motions are provided. Neither recommended relationships are applicable to the nearly harmonic ground motions that may be generated at sites containing soft lakebed deposits. An example illustrates the application of these relationships to a code design spectrum in both the acceleration-displacement and yield point spectra formats.
Development of very‐short‐term load forecasting based on chaos theory

It is indispensable to accurately perform short‐term load forecasting of 10 minutes ahead in order to avoid undesirable disturbances in power system operations. The authors have so far developed such a forecasting method based on conventional chaos theory. However, this approach cannot give accurate forecasting results when the loads consecutively exceed the historical maximum or are less than the minimum. Electric furnace loads with steep fluctuations are another factor degrading the forecast accuracy.
Large Scale Airlift Experiments for Application to Deep Ocean Mining

Deep ocean mining for manganese nodules was the subject of extensive research and development in the 1970s. Recently, the discovery of very rich massive sulfide deposits in deep water has sparked renewed interest in this technology. This paper will report the results of a series of experiments conducted in the late 1970s to validate predictions for the performance of airlift pumping for an ocean mining application. The paper will discuss the sensitivity of airlift performance to proper flow regime maintenance and the comparison between experiments and theory. Implications on full scale system design and control will be discussed.Copyright © 2007 by ASME
Aspergillus proliferans Onychomycosis Forming Fungal Masses

Onychomycosis are nail infections that can be caused by dermatophytes, yeasts or molds, representing the most frequent superficial mycosis worldwide. Dermatophytoma is a variety of onychomycosis characterized by forming fungal masses and it is caused by dermatophytes, particularly Trichophyton rubrum. However, other non-dermatophyte filamentous fungi, including Aspergillus sp. , have been reported. This clinical variety has been associated to failure to conventional antifungal treatment. The aim of this work is to present a clinical case of immunocompromised patient due to transplantation protocol, with diagnosis of onychomycosis caused by Aspergillus proliferans and propose the term onychofungoma to refer to onychomycosis caused by non-dermatophyte filamentous fungi forming
EUVL: towards implementation in production

Cost, cost, cost: that is what it is - ultimately - all about. Single exposure lithography is the most cost effective means of achieving critical level exposures, and extreme ultraviolet lithography (EUVL) is the only technology that will enable this for ≤ 27nm production. ASML is actively engaged in the development of a multi-generation production EUVL system platform that builds on TWINSCANTM technology and the designs and experience gained from the Alpha Demo Tools (ADTs). The ADTs are full field step-and-scan exposure systems for EUVL and are being used at two research centers for EUVL process development by more than 10 of the major semiconductor chip makers, along with all major suppliers of masks and resist. Recently, successful implementation of EUVL for the contact hole and metal layer was demonstrated in the world's smallest (0.099 μm2) electrically functional 22nm CMOS SRAM device [1]. We will highlight the key features of the system description for the production platform, including the manufacturing status of projection lens, illuminator optics, and source. Experimental results from ADT showing the progress in imaging and resist work will be covered as well - a snapshot of imaging data can be seen in the figure below. We will share our vision on the extendability of EUVL by discussing our system implementation roadmap. We will explain our approach for multiple tool generations on a single platform, highlighting the ways to support the technology nodes from 27nm half-pitch with a 0.25NA lens going down to below 16nm with a 0.32NA lens.
Perform light and optic experiments in Augmented Reality

In many scientific studies lens experiments are part of the curriculum. The conducted experiments are meant to give the students a basic understanding for the laws of optics and its applications. Most of the experiments need special hardware like e.g. an optical bench, light sources, apertures and different lens types. Therefore it is not possible for the students to conduct any of the experiments outside of the university’s laboratory. Simple optical software simulators enabling the students to virtually perform lens experiments already exist, but are mostly desktop or web browser based. Augmented Reality (AR) is a special case of mediated and mixed reality concepts, where computers are used to add, subtract or modify one’s perception of reality. As a result of the success and widespread availability of handheld mobile devices, like e.g. tablet computers and smartphones, mobile augmented reality applications are easy to use. Augmented reality can be easily used to visualize a simulated optical bench. The students can interactively modify properties like e.g. lens type, lens curvature, lens diameter, lens refractive index and the positions of the instruments in space. Light rays can be visualized and promote an additional understanding of the laws of optics. An AR application like this is ideally suited to prepare the actual laboratory sessions and/or recap the teaching content. The authors will present their experience with handheld augmented reality applications and their possibilities for light and optic experiments without the needs for specialized optical hardware.
Experimental study of lightning-induced voltage on an overhead wire over lossy ground

Experiments on the lightning-induced voltage on an overhead wire with a simulated lightning channel and a 1/20 reduced-scale model have been carried out on a lossy ground. This method is quite useful in testing various coupling models as repeated measurement along with a simple simulated lightning channel is possible. The electrical characteristics of the ground, indispensable in the calculation of the induced voltage over lossy ground, are evaluated through the comparison of the measured and the calculated horizontal electric field waveforms. The coupling model adopted in the numerical calculation of the induced voltage, including the terminations of a finite line, is verified by the good agreement of the measured and the calculated voltage waveforms. This result also verifies the usefulness of the measurement of the horizontal electric field waveform in assessing the ground conductivity in the frequency range of interest.
