Visible and Invisible Forces. What Drives the Intensity of Trading in the European Carbon Market?
Authors: Kalaitzoglou Iordanis
Published: November 2021

This study models the trading intensity in European Allowances (EUA) futures contracts, in the European Climate Exchange (ECX) using various specifications and investigates the forecasting ability of observable versus unobservable factors. This set up tests empirically the impact of the evolving market structure through regulatory updates and the contribution of the different market participants to the intensity of trading in the European Carbon market. The findings suggest that observable market characteristics capture better the dynamics of trading intensity than their latent counterparts, which implies that regulatory changes that enhance transparency would also improve market efficiency.
Does entry business regulation deter FDI? Evidence from Dynamic Estimators
Authors: Emmanouilidis Kyriakos , Karpetis Christos
Published: November 2021

The present paper aims to examine the effects of entry business regulation on the Foreign Direct Investment (FDI) inflows (net amount) of 185 countries covering a period from 2004 to 2017. For that reason, we estimate a dynamic panel FDI specification, which additionally checks for macroeconomic and institutional factors, using Fixed Effects, Bootstrap Fixed Effects and GMM estimators. Overall, the empirical findings reveal, a negative and statistically significant association between entry regulation and FDI. This suggests that bureaucratic burdens concerning entry regulation can exert adverse effects on the inflow of FDI. Furthermore, when the full sample is separated into different income groups, our findings still indicate evidence of significance, which, however, arises only in the countries of Low and Middle-income.
Fear of Crime and Saving Behavior
Authors: Canare Tristan , Francisco Jamil Paolo S. , Jopson Edgardo Manuel Miguel M.
Published: November 2021

Fear of crime, on top of crime victimization itself, is an important social concern because the literature suggests that it can affect behavior and decision-making. Some studies argue that negative emotions can induce present consumption; thus, one behavior that crime can potentially influence is saving. Applying Logit model and the Heckman Probit model to a household survey dataset of 1,200 respondents, this paper tested for the relationship between fear of crime and saving behavior. We found evidence that fear of crimes involving physical violence has a negative relationship with the likelihood of saving but has a positive relationship with the likelihood of saving through formal channels. Fear of crimes against property, on the other hand, shows no such relationship. Moreover, overall fear of crime in the immediate community has no relationship with saving, but fear of crime in the larger region where the individual lives has.
Trends in Factor Price Elasticities Adding Energy to Capital and Labor in the US Economy
Authors: Thompson Henry
Published: November 2021

This paper estimates trends in factor price elasticities adding energy Btu input to fixed capital assets and the labor force in annual US data from 1949 to 2013. Second order effects improve estimates of the production function in log differences. The unrestricted estimates test for concavity and constant returns to scale. Adding energy input reduces the apparent productivity of labor and reveals strong capital-labor factor price elasticities with pronounced trends. Energy and labor trend to become weak complements. These trends offer insight into recent economic history and keys to predicting the future as well.
Inflation Dynamics: Expectations, Structural Breaks and Global Factors
Authors: Siklos Pierre L.
Published: November 2021

There is no consensus over the importance of “global forces” on inflation. This study explores the role of structural breaks in the inflation process, and their timing, whether it is common across countries, and the extent to which ‘global forces’ are relevant. Three conclusions stand out. Global inflation impacts inflation in both AE and EME, but the impact is more heterogeneous than existing narratives have argued. One’s interpretation of global influences on domestic inflation differs, according to whether poorly performing economies in inflation terms are considered as opposed to the standard practice of examining mean inflation performance. A focus on observed inflation alone ignores that inflation expectations, including a global version of this variable, also plays a critical in inflation dynamics. Finally, there are significant spillovers in inflation between AE and EME, but these too are sensitive according to relative inflation performance. Some policy implications are also drawn.
Trade Liberalization and Productivity Growth: Firm-Level Analysis from Kenya
Authors: Esaku Stephen , Krugell Waldo
Published: November 2021

We analyze the impact of trade liberalization on firm productivity growth in Kenya’s manufacturing sector, using a panel spanning 8 years; 1992-1999. Our analysis reveals that liberalizing trade generates high productivity improvements in the manufacturing sector. We find that a one-unit reduction in import duties as a percentage of total imports significantly increases firm-level productivity in the manufacturing sector by 5.7%. When we examine this effect on the firm’s share of exported output, we find that lowering of import duties significantly increases the share of output exported by 0.7%. Further, we sought to assess how the effect of import duties varied across the different industries in our sample. Examining the effect of import duties on industrial performance, we find a negative and statistically significant relationship in some of the industries. Our results show heterogeneous effect of reduction of import duties on industrial performance. Not all industries benefited from the lowering of import duties, especially the food and bakery, and garment industry, where productivity did not increase. These findings have important policy implications for improving the manufacturing sector. Consequently, formulating policies that effectively relax restrictive barriers to trade in the economy could speed up firm-level productivity in the manufacturing sector.
Social Evils – From Unemployment to Idleness to Prejudice. Some Suggestions for Mapping the Modern Equivalents of These Old Evils onto New Injustices
Authors: Dorling Danny
Published: November 2021

In the midst of World War II the economist William Beveridge christened five social evils, all to be eradicated in Britain: ignorance, want, idleness, disease and squalor. Although Britain took its lead from developments elsewhere, to an extent that would have been hard to imagine in the 1930s, the very worst manifestations of each of these five evils had been overcome by the 1970s. However, from then onwards each evil transformed its appearance. In this paper I briefly argue that the new form of the five had features respectively of revised elitism, exclusion, prejudice, despair and greed.
Inter- and intraindustrial Job-to-Job Flows. A Linkage Analysis of Regional Vacancy Chains in Austria
Authors: Aumayr Christine M.
Published: November 2021

Nine Austrian NUTS 2 inter- and intraindustrial job-to-job worker flows for 33 industries
are analysed by means of input-output techniques, with these job-to-job flows being
an intermediate input in the production of filled vacancies. A new dataset on individual
labour market episodes allows for the tracing of individual careers. A linkage analysis
of the Leontief multiplier shows that business services, wholesale&retail and the metal industry
are ‘key’ industries in for- and backwarding employment, whereas construction
and tourism exert an impact on other regional industries by absorbing workers upon aggregate
external shocks. These findings can be incorporated in industrial employment
forecasts or utilized in regional labour market impact studies.
Size Distortion of Bootstrap Tests: an Example from Unit Root Testing
Authors: Davidson Russell
Published: November 2021

Testing for a unit root in a series obtained by summing a stationary MA(1) process with a parameter close to -1 leads to serious size distortions under the null, on account of the near cancellation of the unit root by the MA component in the driving stationary series. The situation is analysed from the point of view of bootstrap testing, and an exact quantitative account is given of the error in rejection probability of a bootstrap test. A particular method of estimating the MA parameter is recommended, as it leads to very little distortion even when the MA parameter is close to -1. A new bootstrap procedure with still better properties is proposed. While more computationally demanding than the usual bootstrap, it is much less so than the double bootstrap.

On the Incentives to Increase Input Efficiency under Monopoly Trade Unions
Authors: Biswas Tapan , McHardy Jolian
Published: November 2021

We examine the effects of and the incentives for increasing input efficiency within a spatially segregated  Cournot duopoly with monopoly trade unions whose utility functions depend on both wages and employment. We show that with neoclassical as well as Leontief technology, unions raise wages to appropriate fully the gains from labor-saving technological (or organisational) improvements, leaving the firm with no incentive to invest in increasing the efficiency of workers. However, capital-saving     technological improvement may be profitable depending on the elasticity of substitution. Finally, we examine the implication of a fixed minimum wage (or competitive labor market) in one country.

Examining the Tradeoff Between Fixed Pay and Performance-Related Pay: A Choice Experiment Approach
Authors: Shen Junyi , Ogawa Kazuhito , Takahashi Hiromasa
Published: November 2021

Previous investigations on performance-related pay have mainly analyzed its relationships with earnings, productivity, and job satisfaction. Less attention has been devoted to the investigations of individuals’ preferences for the performance-related payment system per se and consequently the tradeoff between fixed pay and performance-related pay. In this paper, we first use a choice experiment approach to investigate the tradeoff between fixed pay and performance-related pay, and then link the tradeoff for each individual with their risk preferences. Our main results indicate that individuals’ preferences for the payment system per se and the magnitude of tradeoffs between fixed pay and performance pay are different according to their risk preferences.

Weinvestigate the relationship between Twitter content categorized as sentiments, such asBuy, Sell and Neutral, with USD/TRY currency movements. The results suggest thatthere exists a relationship between the number of tweets and the change in USD/TRYexchange rate.
Firm Corruption in the Presence of an Auditor
Authors: Dietrich Michael , Mchardy Jolian , Sharma Abhijit
Published: November 2021

We develop a theoretical framework exploring firm corruption accounting for interactions with an auditor who provides auditing and other services. A multiplicity of equilibria can exist including stable corruption and auditor controlled corruption. Whilst fining the auditor cannot eliminate all corruption, fining the firm can, but marginal increases in this fine can also have perverse effects. Investing in corruption detection may be effective in deterring auditor corruption but ineffective in deterring firm corruption. Policy effectiveness is highly dependent upon several factors which may be hard to observe in practice making general rules about policy interventions to address corruption very difficult.
Explaining Private Debt
Authors: Uusküla Lenno
Published: November 2021

The paper examines the relationship between more than 30 macroeconomic variables and debt-to-GDP ratios for the household, non-financial corporation and aggregate debt in a panel of European Union countries. The GDP level and the ratio of house prices to income are found to be positively correlated with the debt-to-GDP ratio, whereas the real interest rate, the inflation rate, economic sentiment and the government debt level are negatively correlated with the debt-to-GDP ratio. Low interest rates and the house price-to-income ratio predict growth in the future debt-to-GDP ratio. Moreover, countries that have had a financial crisis have typically gone through a period of deleveraging afterwards.
Design of a stationary disc chipper project for dendromass chipping with stress analysis FEM methods
Authors: Krilek Jozef , Tichý Branislav , Kováč Ján , Melicherčík Ján , Kuvik Tomáš
Published: November 2021

The design of a stationary disc wood chipping machine was considered, as well as the stress-strain analysis of a cutting knife with a flat and shaped cutting edge, which will produce a dimensional chip. The design consisted of the conceptual design of a cutting knife, a cutting mechanism, and an entire disc chipping machine, which includes cutting tools. The design solution is based on mathematical calculations of the individual parts of the cutting device. Calculations of the cutting mechanism and the cutting tool were performed using the finite element method. The results of the stress analysis found that the maximum stress acting on the edge of the knife during cutting corresponded to the permissible stresses of the knife material and subsequent use in practice. Based on the design and physical parameters of the wood cutting process, the design of the entire chipping machine was simulated and then was modeled using the PTC Creo parametric 5.0 program. Additional finite element analysis was performed using the Creo Simulate 5.0 software.
Effect of microwave and steam treatment on the thermo-hygro-plasticity of beech wood
Authors: Dömény Jakub , Brabec Martin , Rousek Radim , Rautkari Lauri , Čermák Petr
Published: November 2021

The effects of microwave and steam treatment were analyzed relative to the immediate (thermo-hygro-plasticity) and post-assessed (permanent changes) properties of wood. The study was conducted using European beech (Fagus sylvatica L.) standard and 1.5 times up-scaled (only for microwave-heated and reference samples) bending specimens tested in a static three-point loading mode. The specimens were plasticized by heat and moisture (1) separately and (2) simultaneously by heating moist specimens using (i) various microwave regimes in continuous mode, and (ii) heated saturated steam in discontinuous mode. Oven-dried specimens tested at 20 °C served as references. The thermo-hygro-plasticity was studied immediately after treatment, whereas the permanent changes were assessed after oven-drying of plasticized specimens to 0% moisture content. Permanent structural changes were analyzed using scanning electron microscopy. Microwave treatment increased the plasticity of wood (decreasing the modulus of elasticity by 70%) comparably to steam treatment, when the output moisture content was 30% or higher. A similar degree of plasticity was found in up-scaled specimens heated by microwaves. Further analyses confirmed that microwave treatment did not cause any permanent damage to wood structure or reduce mechanical performance. The results showed that microwave treatment is an efficient alternative to steaming when plasticizing moist wood.
The Textology of the Synaxarian Life of Menas, Hermogenes, and Eugraphus, Martyrs of Alexandria
Authors: Čistiakova Marina
Published: November 2021

The abridged life of Menas, Hermogenes, and Eugraphus, martyrs of Alexandria, was translated from Greek as part of the Church Slavonic Synaxarion no later than in the early 12th century. Notably, the main version of this life does not contain any data on St Eugraphus. One of the earliest copies of the Synaxarion has lost the headline of the life of martyr Gemellus, whose memory is mentioned on the same day, while the corresponding text was added to the life of the saints of Alexandria. The scribe’s error has led to the emergence of a classifying feature that allows dividing the versions of the oldest translation of the Synaxarion into two groups. The first group consists of the main version ofthe life (Sof. 1324 and most other copies of the Ordinary Synaxarion). The second group encompassesthe extended by the life of Gemellus edition (copies of the Bulgarian version of the Synaxarion andseveral copies of the abridged version). In the Serbian version of the Synaxarion the main version ofthe life was supplemented with fictitious data about martyr Eugraphus. Apart from the versions of theOrdinary Synaxarion, two independent translations of the Versed Synaxarion were made from Greek toChurch Slavonic in the 14th century. One of them relates to the Bulgarian book tradition and the otherone follows the Serbian one. Each of the two translations includes the new life of Alexandria’s martyrssupplemented with verses. Between the 1630s and 1640s, Ukrainian scribes of the Commonwealth ofthe Two Nations created yet another version of the life, where the main version was supplemented withdata of martyr Eugraphus from the Bulgarian translation of the Versed Synaxarion. Thus, the abridgedlife of the martyrs of Alexandria is known in three translations, with the oldest one of them availablein four versions.
The best, by coefficients, weighted quadrature formulas of the form $\sum\limits_{k=1}^n \sum\limits_{i=0}^{r-1} A_{ki} f^{(i)}_{jk}$ for some classes of differentiable functions

Published: November 2021

For the quadrature formula (with non-negative, integrable on $[0,1]$ function) that is defined by the values of the function and its derivatives of up to and including $(r-1)$-th order, we find the form of the best coefficients $A^0_{ki}$ ($k = \overline{1, n}$, $i = \overline{0, r-1}$) for fixed nodes $\gamma_k$ ($k = \overline{1, n}$) and we give the sharp estimate of the remainder of this formula on the classes $W^r_p$, $r = 1, 2, \ldots$, $1 \leqslant p \leqslant \infty$.

Published: November 2021

We obtain upper bound of the best approximation of the classes $H^{\omega} [a, b]$ by piecewise-constant functions over uniform split in metrics of $L_{\varphi}[a, b]$ spaces, which are generated by continuous non-decreasing functions $\varphi$ that are equal to zero in zero. We study the classes of functions $\varphi$, for which the obtained bound is exact for all convex moduli of continuity.

Modelling soil desiccation cracking by peridynamics
Authors: Yan Huaxiang , Jivkov Andrey P. , Sedighi Majid
Published: November 2021

Understanding of desiccation-induced cracking in soil has improved over the last 20–30 years through experimental studies, but progress in predictive modelling of desiccation cracking has been limited. The heterogeneous structure of soils and the multi-physics nature of the phenomenon, involving emergence and propagation of discontinuities, make the mathematical description and analysis a challenging task. The authors present a non-local hydro-mechanical model for soil desiccation cracking capable of predicting crack initiation and growth. The model is based on peridynamics (PD) theory. Attempts to model soil desiccation cracking by PD are limited to a purely mechanical description of the process that involves calibration of the parameters. In contrast, the model presented in this paper describes soil desiccation cracking as a hydro-mechanical problem, where moisture flow and deformation are coupled. This allows for investigating and explaining the mechanisms controlling the initiation and propagation of discontinuities. The model is applied and tested against two sets of experimental data to explain the typical features of drying-induced cracking of clays. The validations use experimental parameters (Young's modulus, water retention characteristics) and avoid calibrations to test the accuracy of the model. The correlations between the shrinkage of soil clay, changes in displacement fields and crack growth are demonstrated. Crack initiation, propagation and ultimate crack patterns simulated by the model are found to be in very good agreement with experimental observations. The results show that the model can capture realistically key hydraulic, mechanical and geometry effects on clay desiccation cracking.
¿HA AFECTADO LA PANDEMIA POR COVID-19 AL VOLUMEN ASISTENCIAL DE URGENCIAS POR CAUSA ALCOHÓLICA? ESTUDIO DE INCIDENCIA Y ANÁLISIS DESCRIPTIVO
Authors: Felip Fucho Genís , Guinovart Martí , Delgado Laia , Capilla Alicia , Parra Isabel , Palao Diego José
Published: November 2021

Descripción precisa de los objetivos: estudios previos han señalado una tendencia global al incremento del consumo de alcohol coincidiendo con la pandemia por COVID-19, aunque la demanda asistencial por esta causa ha variado según el entorno y las políticas sanitarias. El objetivo del presente estudio es analizar el efecto de la pandemia sobre el número de asistencias relacionadas con el alcohol (ARA) en Urgencias. Material y métodos: diseño longitudinal retrospectivo. Se ha realizado una revisión mensual de todas las ARA atendidas en Urgencias del Hospital Parc Taulí (Sabadell) durante el período pre-COVID (marzo 2019 a febrero 2020) y COVID (marzo 2020 a febrero 2021). Definición de ARA: (1) motivo de consulta relacionado con el alcohol, registrado por Enfermería en el momento del triaje; o (2) diagnóstico principal relacionado con el alcohol, registrado por el/la médico/a en el momento del alta. La información obtenida se ha cuantificado tanto en términos absolutos (número de ARA) como relativos (número de ARA sobre el total de visitas en Urgencias) y, posteriormente, se han comparado ambos períodos mediante un test de Mann-Whitney. Resultados y conclusiones: durante la época COVID, se ha confirmado una reducción del número de ARA (p<0,001) que se ha correlacionado con la disminución global del número de Urgencias. A nivel porcentual, sin embargo, estas asistencias han aumentado en ambos géneros, aunque sin alcanzar la significación estadística. El patrón de consumo de los varones ha sido más estable, mientras que en las mujeres se disparó de forma significativa durante los meses de verano. A pesar de que existen limitaciones metodológicas (cambios legislativos y sociales en época COVID, accesibilidad al tóxico...) que dificultan la plena comparabilidad de ambas muestras, nuestro análisis sugiere una asociación entre la situación de pandemia y la demanda asistencial por alcohol en Urgencias que debería ser profundizada en futuros estudios.

Authors: Zirakashvili Medea , Mikiashvili Tamar , Mebonia Nana , Gabunia Maia
Published: November 2021

Introduction Autism spectrum disorder (ASD), complex neurodevelopmental condition with lifelong impacts, typically identified in early childhood. Despite the fact that 95% of all <5 years of age with developmental disabilities including ASD live in low- and middle-income countries, the prevalence of ASD in many these countries is unknown. Objectives and goals The study aimed to identify the prevalence and clinical characteristics of ASD and its comorbidities among 8-10 y old schoolchildren in Republic of Georgia. Material and Methods The study conducted in four steps: screening, sampling, diagnostic assessment, and quality control of best-estimate diagnosis with target population of 3rd grade students of five main cities (Tbilisi, Kutaisi, Batumi, Zugdidi, Telavi) of Georgia (N=22,553). To determine children at risk for ASD the Autism Spectrum Screening Questionnaire (ASSQ) was used completed by parents and teachers. Parents of children who screened positive were offered comprehensive assessment using standardized diagnostic procedures. Results and Conclusions 16654 (response rate 74%) parents were agreed to participate in the screening stage. Cut-off scores for 99-95 percentiles (top 1-5%) was defined. For the 1168 sampled screen-positive students 704 (60.3%) consented to participate in the diagnostic assessment, and 215 among them (30.5%) completed full assessment. The control group of 23 children (from non in top 10%) were fully assessed for ASD. The prevalence of ASD was estimated to be 1.34% (95%CI=2.15-4.41). From ASD group 77.5% of cases were undiagnosed to have any neurodevelopmental disorder. Comorbidity of Intellectual disability was in 22.5% of children with ASD (IQ<70), and 31% have IQ>111. The study defined need for the use of broader screening in primary healthcare and school settings to identify children with special needs and ensure their adequate services.
CHEMSEX: LA FUSIÓN ADICTIVA DE DROGAS, SEXO Y SALUD MENTAL
Authors: Moura Nuno , Esteves-Sousa Daniel , Fraga Margarida , Facucho-Oliveira João , Laginhas Catarina , Pereira Sérgio
Published: November 2021

Introductión e objetivos: Chemsex se define como el uso de ciertas sustancias inmediatamente antes o durante las actividades sexuales para facilitar, prolongar y/o intensificar la experiencia sexual, principalmente por algunas comunidades de hombres que tienen sexo con hombres (HSH). Las sustancias asociadas incluyen catinonas sintéticas, metanfetamina, gamma-butirolactona / gamma-hidroxibutirato, ketamina y fármacos para el trastorno eréctil. La práctica de combinar sustancias psicoactivas y sexo ha aumentado de manera constante con el desarrollo de aplicaciones móviles. El advenimiento de las aplicaciones de geolocalización transformó la forma en que las personas se encuentran y contribuyó al desarrollo de chemsex. Si bien hay mucha evidencia de una mayor prevalencia del VIH, infecciones de transmisión sexual y otras medidas de salud sexual entre los HSH que practican chemsex, ha habido poca investigación sobre los aspectos de la salud mental. Nuestro objetivo es realizar una revisión no sistemática de la literatura sobre el chemsex y los posibles problemas de salud mental asociados. Material e métodos: Se realizó una revisión semiestructurada en Pubmed sobre chemsex y salud mental. Resultados e discussión: En la literatura publicada sobre chemsex, el foco aún se encuentra en las comorbilidades somáticas. Los trastornos mentales como la depresión, la psicosis inducida por sustancias y la adicción también parecen ser una consecuencia importante del chemsex. Existe una necesidad de asesoramiento adaptado a los usuarios de chemsex y sus necesidades, que generalmente no se centra solo en la abstinencia, y que también deba incorporar estrategias de reducción de daños. Conclusiones: Chemsex es un tema complejo que se encuentra en la encrucijada de la sociología, la medicina infecciosa, la adicción y la sexología. Algunos usuarios se involucran en chemsex en busca de desinhibición sexual, otros para abrazar sus preferencias sexuales y otros aún por los efectos de las drogas.
Real vs. Virtual City: Planning Issues in a Discontinuous Urban Area in Budapest’s Inner City

Published: November 2021

The 21st century has brought fundamental changes in the development of cities, with the spread of ICT and the rise of digitalization. The new technologies are increasingly making their mark on urban planning and policy as well. The question of how contemporary urban planning is adapting to new challenges is particularly relevant as neighborhoods built in previous centuries and decades by traditional planning methods are now increasingly confronted with new public and environmental demands. Despite the bad reputation of Budapest’s 8th district, Józsefváros, based on the socio-economic and urban problems it has continuously faced in the past, the neighborhood has become one of the most dynamically developing urban areas in the last decade. From a planning point of view, an exciting area of the district is Szigony Street and its wider surroundings due to the strongly fragmented, heterogeneous urban fabric. Nevertheless, the only high-rise mass housing estate built in Budapest’s historic inner city in the 1960s and 1970s is located there. Our research used a complex methodology (document, content and database analysis, fieldwork, surveys with professionals, and interviews) to explore the planning history of the area’s development. Ultimately, the aim was to identify the most important outcomes and consequences of traditional and contemporary planning and design and whether modern digital planning can make a meaningful contribution to the development of the neighborhood. Our results show that urban planning and development in Budapest are still essentially based on traditional top-down approaches. Digitalization has a role to play primarily in visualization and contextualization but digitalizing of planning alone will not solve problems and past planning mistakes that affect the urban fabric of a neighborhood.

Published: November 2021

This mixed-methods study explores the effects of adaptive leadership on faculty engagement in online learning in higher education. The higher education environment is rapidly changing due to students seeking more flexible and online learning opportunities. This change which was already developing in response to the 2025 enrollment cliff (when the number of high-school graduates in the United States will drop significantly) and has only been accelerated by the COVID-19 pandemic. Therefore, the purpose of this study was to investigate the influence of adaptive leadership on faculty engagement in online education at institutions of higher education. This study was conducted through a pragmatic paradigm with a constructivist lens . The conceptual framework for this research study was built upon a thorough review of the literature, examining three research streams: (a) faculty perception of online learning, (b) change management, and (b) adaptive leadership. Seventy-seven faculty from four colleges at a large university in the northeast completed a survey and then eight faculty participated in follow-up interviews. The quantitative data were analyzed using SPSS to look at descriptive and inferential statistics. The qualitative data were analyzed using NVivo for open and axial coding. The research revealed five results: (a) the climate of a school/college effects perception of and participation in online learning; (b) faculty want to be acknowledged and rewarded for participation in online learning; (c) Institutions of Higher Education looking to move online need to secure faculty buy-in and provide faculty support (d) faculty's perception of online learning has shifted over time, and exposure to online and remote learning during the COVID-19 pandemic shifted perceptions in a positive way; and (e) faculty's perception of online learning is not affected by participation in professional development or by working with an instructional designer; however, instructional design support was highly valued. Based on these results, five recommendations were made for institutions wishing to move into online learning: (a) faculty should decide to opt-in to online teaching; (b) protect faculty time; (c) recognize faculty contributions (d) provide support to faculty; (e) invest in instructional designers.

La cantidad de preconceptos que los alumnos poseen antes de abordar el estudio de un tema influye de manera notable en la adquisición de nuevos conocimientos. Se ha diseñado una estrategia de enseñanza aprendizaje basada en el uso de cuestionarios y prácticas de ordenador realizadas con Easy Java Simulations. Las áreas trabajadas fueron mecánica, electromagnetismo y termodinámica. Se han detectado varias ideas preconcebidas y erróneas sobre todo en la parte de mecánica. Los resultados obtenidos muestran que la estrategia diseñada ha resultado útil al cometido abordado.

Published: November 2021

La metodología docente de las asignaturas de Puertos y Costas emplea las visitas a obra y al laboratorio CITEEC como una parte de sus herramientas fundamentales. El confinamiento generado por la pandemia del COVID-19 obligó a adaptar dicha metodología, sustituyendo dichas visitas por la exposición de videos de ensayos y de los fenómenos físicos explicados en clase. Por otro lado, fue necesaria una adaptación de la evaluación. Se aumentó el peso de la evaluación continua y se disminuyó el del examen final. Los resultados alcanzados mostraron que la exposición de videos no permitía que el alumnado comprendiera los fenómenos físicos de una forma tan clara como antes, y, además, las clases virtuales generaban una menor participación. Por último, aunque la modificación en la evaluación ha permitido aumentar la tasa de aprobados, esta generó una mayor dificultad para evaluar de una forma individual los conocimientos del alumnado.

Published: November 2021

Ante la imposibilidad de acudir de manera presencial a la realización de determinadas prácticas clínicas, debido a la vulnerabilidad de sus usuarios frente al COVID-19, la Facultad de Fisioterapia ha decidido que unos determinados bloques de contenidos clínicos se impartan de manera presencial en los laboratorios destinados para tal fin en la propia Facultad. Ante esta situación, surge la idea de utilizar videos de pacientes reales del centro al que no podemos acudir de manera presencia, para ser utilizados como recurso didáctico de apoyo en la impartición de la Estancia Clínica II (4º curso). Tras obtener el consentimiento por parte del centro clínico, se procede a grabar 32 casos clínicos, en videos de 12-15 minutos, con el objetivo de ser utilizados como recurso didáctico de apoyo en la impartición de dicha materia, durante todo el 2º cuatrimestre (febrero-mayo 2021; 14 semanas), para trabajar con los alumnos el proceso de "razonamiento clínico", además de pretender acercarlos a una realidad clínica.
