Published: February 2024

Recently, global interest in organizing the functioning of renewable energy resources (RES) through microgrids (MG) has developed, as a unique approach to tackle technical, economic, and environmental difficulties. This study proposes implementing a developed Distributable Resource Management strategy (DRMS) in hybrid Microgrid systems to reduce total net percent cost (TNPC), energy loss (Ploss), and gas emissions (GEM) while taking the cost-benefit index (CBI) and loss of power supply probability (LPSP) as operational constraints. Grey Wolf Optimizer (GWO) was utilized to find the optimal size of the hybrid Microgrid components and calculate the multi-objective function with and without the proposed management method. In addition, a detailed sensitivity analysis of numerous economic and technological parameters was performed to assess system performance. The proposed strategy reduced the system’s total net present cost, power loss, and emissions by (1.06%), (8.69%), and (17.19%), respectively compared to normal operation. Firefly Algorithm (FA) and Particle Swarm Optimization (PSO) techniques were used to verify the results. This study gives a more detailed plan for evaluating the effectiveness of hybrid Microgrid systems from a technical, economic, and environmental perspective.

Published: February 2024

Deficits in social cognition in attention deficit hyperactivity disorder (ADHD) have been associated with difficulties in functioning. Since recognizing emotional facial expressions is essential for developing the perceptual components of the theory of mind (ToM), it is important to assess this relationship in children with ADHD. This study therefore compared the recognition of emotional stimuli and gaze patterns between children with ADHD and healthy children using eye-tracking with dynamic facial images. It also examined the relationship between facial emotion recognition accuracy, gaze patterns, ToM scores, and ADHD symptoms. Children with ADHD aged 8–13 (n = 47) and a control group (n = 38) completed a facial emotion recognition test, ToM tests, and the Conners’ Parent Rating Scale. Participants’ gaze patterns in response to dynamic facial emotion expressions were recorded using eye-tracking technology. Children with ADHD exhibited significantly lower accuracy in the recognition of the facial expressions of disgust and anger. The percentage fixation in the eye region was also significantly lower for happy, angry, sad, disgusted, and neutral emotions in the children with ADHD compared to the control group. No relationship was determined between the percentage of fixations on facial areas of interests and ADHD symptoms or ToM tests. This study provides evidence that children with ADHD experience deficits in visual attention to emotional cues. In addition, it suggests that facial emotion recognition deficits in children with ADHD represent a separate domain of social cognition that develops independently of ToM skills and core symptoms. Understanding and treating the social difficulties of individuals with ADHD may help improve their social functioning.
El pastor extravagante
Authors: Sorel Charles , Gonzalo Santos Tomás
Published: February 2024

El pastor extravagante (1627-1628) relata la historia de un joven parisino llamado Louis, huérfano de padres enriquecidos en el comercio de la seda y lector tan empedernido de novelas –pastoriles, sobre todo– que acaba tomando el sobrenombre de Lysis, se desplaza a la localidad cercana de Saint-Cloud, compra unas ovejas y decide llevar una vida semejante a lo leído en sus libros. Allí lo encuentra Anselme, a quien sorprenden sus extravagancias. La aparición oportuna del primo y tutor de aquel, Adrian –que intentará, reiterada e infructuosamente, llevárselo a París–, permite conocer las causas de su conducta a Anselme, que se ofrece a acoger a Lysis y a cuidar de él, pero con el ánimo de recrearse con su locura. Las conversaciones que mantienen le revelan que el pastor se ha prendado de una tal Catherine, bautizada por este como Caritea y tan idealizada en su imaginación como la Dulcinea quijotesca. Anselme lleva a Lysis con engaños a la región de Brie y es recibido y agasajado por los amigos de Anselme, burgueses o nobles retirados al campo. Allí conoce a Carmelin, que convertirá en sanchopancesco compañero de sus andanzas pastoriles; y allí, además de las excentricidades en que incurre por iniciativa propia, será objeto de toda una serie de burlas y farsas organizadas por sus anfitriones con la intención de divertirse a su costa. La obra concluye con un final inesperado y está trufada de numerosas referencias mitológicas y librescas, así como de una acerba crítica literaria que la convierten en paradigma de la transtextualidad. Se ofrece aquí la primera traducción al castellano de la novela de Charles Sorel, precedida de una introducción que repasa la vida y obra de este polígrafo infatigable, y seguida de un estudio en el que se analizan las relaciones que establece el texto con la ficción anterior y, en particular, la impronta decisiva del Quijote.

Published: February 2024

O letramento informacional é um processo importante para conscientizar sujeitos nas etapas de seleção, acesso e consumo da informação. Ademais, o letramento midiático está ligado ao anterior, pois diz respeito a habilidade de selecionar e apropriar do tipo de informação encontrada no meio virtual, principalmente, as informações compartilhadas nas mídias sociais. Nesse contexto, se letrados informacional e midiaticamente, os sujeitos estão aptos a desenvolver a competência informacional, conhecimento que propõe autonomia para o usuário no que tange a sua capacidade de pesquisar e adquirir somente as informações que lhe são pertinentes. O bibliotecário torna-se papel importante nesses processos, devido a sua capacidade de mediação da informação. O objetivo geral da pesquisa é discutir sobre letramento informacional, midiático e competência informacional e qual a colaboração do bibliotecário nesses processos. Este ensaio teórico, classifica-se como uma pesquisa descritiva, bibliográfica, qualitativa e teórica-analítica, pois procura debater diferentes definições e visões de autores que contribuem para os temas levantados por meio da revisão não sistêmica da literatura. Conclui-se que os processos de letramento informacional, midiático e competência informacional são fenômenos importantes para a criação de uma sociedade autônoma informacionalmente e consciente do seu impacto no campo virtual, instruindo-a a utilizar de forma mais autônoma as mídias sociais. Assim, também, o bibliotecário é figura fundamental nesse contexto, visto que a mediação é uma das funções primordiais do profissional e habilidade necessária para o ensino dos letramentos.
Comunicação e competência em informação

Published: February 2024

A midiatização influencia opiniões e comportamentos através dos meios de comunicação; meios estes que também estimulam o consumo e moldam padrões de compra. A competência em informação é fundamental para discernir informações verdadeiras de falsas, especialmente em um contexto de desinformação, onde notícias enganosas se espalham facilmente, afetando a opinião pública. A pesquisa tem como objetivo estudar a interdisciplinaridade dos estudos teóricos da comunicação, midiatização e consumo, com foco na competência em informação para o combate à desinformação. A pesquisa caracteriza-se como descritiva, de abordagem qualitativa e natureza básica, fazendo uso do método de pesquisa bibliográfica e revisão da literatura para discussão das temáticas: Calhoun (2012), França (2003) e Sodré (2007) para contextualização da Comunicação; Dudziak (2003), Santos e Santos (2022) e Vitorino e Piantola (2020) para discussão da Competência em Informação. Ao estabelecer uma relação consciente e crítica à midiatização, consumo e CoInfo, construiremos uma sociedade mais informada, capaz de tomar decisões mais importantes que possam contribuir nos debates da vida pública e política.

Podcasts contra a desinformação
Authors: Pires Thalía da Silva , Costa Camila Martineli
Published: February 2024

No atual contexto de infodemia, isto é, de disseminação ininterrupta de informações, os podcasts vêm transformando seus conteúdos de modo a contribuir para a divulgação da informação verdadeira e de fonte confiável. Com a demanda crescente por informações confiáveis e embasadas em evidências, os podcasts institucionais surgem como meio alternativo de comunicação para promover a divulgação científica à comunidade. Nesse sentido, este trabalho tem como objetivo mapear os episódios relacionados aos termos "fake news" e "notícias falsas" disponíveis na plataforma Lúmina Podcasts, da Universidade Federal do Rio Grande do Sul, discutir seus resultados e analisar os conceitos de fake news, desinformação e notícias falsas dentro do contexto contemporâneo de infodemia. A metodologia utilizada foi qualitativa, mapeando e descrevendo os programas de podcasts da universidade que abordam esses temas. Como resultado, observou-se um notável engajamento do Lúmina Podcasts na divulgação científica e no combate às fake news. Os episódios mapeados abrangem diversas áreas do conhecimento, incluindo saúde, ciência da informação e humanidades, garantindo que público amplo possa expor-se aos assuntos relativos à desinformação, bem como as fake news. Podemos concluir que o uso dos podcasts como ferramenta para disseminar informações confiáveis é uma necessidade, esperamos que essa iniciativa inspire outras instituições a implementarem seus próprios podcasts. Todavia, é preciso reconhecer que, apesar da existência desses podcasts, a facilidade de compartilhar informações nas plataformas de comunicação digital ainda permite que as fake news se espalhem rapidamente. Para romper com a falta de confiabilidade nas informações e desmistificar a desinformação, o papel do divulgador científico em meio a infodemia está também em apropriar-se de todos os recursos possíveis para fazer o intercâmbio facilitado das informações entre o âmbito acadêmico e o grande público.

Background
Cancer and diabetes are risk factors for COVID-19 mortality rates. Remdesivir, dexamethasone, and vaccines are used to improve clinical outcomes. We aimed to evaluate the factors associated with COVID-19 mortality rates.

Methods
This retrospective study enrolled moderate to critical COVID-19 patients. The index day was the day of the COVID-19 diagnosis. Patients were followed up until either death or discharge. A two-way analysis of variance examined the interaction between independent mortality risk factors.

Results
A total of 205 patients were analyzed, and the mortality rate was 29.5% (n=60/205). The cumulative survival rate was significantly lower in patients with a CCI score ≥ 6, cancer, and diabetes. In multivariate analysis, critical illness, cancer, diabetes, chronic liver disease, a CCI score ≥ 6, unvaccinated, and early use of remdesivir/dexamethasone were independent risk factors for mortality. The onset of remdesivir/dexamethasone ≥ 2 days and < 3 doses of vaccinations were higher mortality rate, with its impact being more significant amongst patients with cancer/diabetes, compared to those without cancer/diabetes (p for interaction = 0.046/0.049, 0.060/0.042, and 0.038/0.048 respectively).

Conclusions
COVID-19 vaccination ≥ 3 doses and early administration of remdesivir and dexamethasone can significantly reduce mortality rates, particularly in patients with cancer or diabetes.

Published: February 2024

Este artículo tiene como objetivo describir las distintas formas de percibir el cuerpo como territorio en mujeres que ejercen la prostitución en el sector de La Veracruz en Medellín (Colombia) a partir de sus narrativas. Este corresponde a un estudio cualitativo de nivel descriptivo enmarcado en el paradigma interpretativo hermenéutico y el método fenomenológico clásico. Para la recolección de la información se emplearon como técnicas una entrevista semiestructurada y la cartografía social. Los datos se analizaron a través de un proceso de codificación que permitió la identificación de categorías emergentes con apoyo del software Atlas Ti. Los resultados muestran que desde la visión que tienen las mujeres que ejercen la prostitución es posible percibir el cuerpo como un espacio que está integrado por lo emocional, lo conductual, lo expresivo y lo vivencial que se reconoce así mismo como un territorio que puede ser habitado y cambiante, que la historicidad de este y los conflictos que le atraviesan, le permiten ser reconocido como una herramienta de lucha, constancia e interpretación.

n-Defendant Litigation and Settlement: The Impact of Joint and Several Liability
Authors: Kornhauser Lewis A. , Takeda Keith T.
Published: February 2024

This article generalizes the analysis of settlement under joint and several liability from lawsuits involving one plaintiff and two defendants to those involving n ≥ 2 defendants. We demonstrate that, depending upon the correlation of outcomes among the defendants, but regardless of the distribution of liability shares, joint and several liability may encourage plaintiffs to select some defendants for litigation while settling with those remaining. In particular, under joint and several liability, when each defendant is grouped with others sharing correlated outcomes, and the plaintiff’s probability of success against any defendant is sufficiently high, we show that, in all Nash equilibrium, the plaintiff litigates against the defendant from each group with the smallest share and settles with all other defendants. There are a continuum of equilibria but they are all payoff-equivalent up to permutation. Plaintiff’s payoff is identical in all equilibria; only the payoffs of the members with the smallest share within a group are permuted. We also show that, for sufficiently high plaintiff’s probability of success, this result holds even when the defendants are allowed to form coalitions, and derive the set of offers in the behaviorally unique coalition proof Nash equilibrium; as before, these offers induce litigation against the defendant with the smallest share in each group and settlement with all other defendants.
Potential Elitism in Selection to Bilingual Studies: A Case Study in Higher Education
Authors: Barrado-Timón Diego A.
Published: February 2024

This research provides information toward answering the question of whether bilingual studies at the university level might be elitist. This is a recurring research topic in terms of using English for nonlanguage instruction at the primary and secondary levels, but very few studies refer to university education. We seek to fill that gap in the literature by way of a case study centered on the International Studies degree offered by the Universidad Autónoma de Madrid in Spain. A survey was conducted of students in this program inquiring as to the educational and language levels of their parents as well as their possibilities for exposure to English during secondary (high school) education. The analysis of this quantitative data, student’s grades, and qualitative responses gathered through interviews with program professors does not allow us to affirm the presence of class bias in said institution during student selection for the bilingual track; nor are students in the bilingual group found to have obtained better academic outcomes than their peers in the monolingual group.
Effect of asphalt modified with waste engine oil on the durability properties of hot asphalt mixtures with reclaimed asphalt pavement
Authors: Abd Ali Nadia S. , Joni Hasan H. , Al-Rubaee Rasha H. A.
Published: February 2024

The increased demand for asphalt and other materials involved in the construction of pavement led to an increase in the cost of these materials, which calls for searching for alternatives to virgin materials that can be used to produce asphalt mixtures. Reclaimed asphalt pavement (RAP) was employed in this study and regenerated using oxidized asphalt modified with waste engine oil (WEO). This method can achieve economic and environmental benefits. After improving the properties of oxidized asphalt using WEO, it was used with reclaimed asphalt mixtures (RAP). When the RAP was added at ratios of 20, 30, 40, and 50%, an improvement can be noticed in the mechanical performance of the asphalt mixtures renewed with oxidized asphalt and WEO and an increase in its resistance to stripping. When reclaimed asphalt pavement (RAP) is added to hot mix asphalt (HMA) at concentrations of 20, 30, 40, and 50%, respectively, the Marshall stability of HMA is improved by 10, 20, 28, and 9.5%, the flow is declined by 1% for all ratios of RAP except for 50% RAP where the flow decline by 3%, the unit weight is enhanced, the quantity of air voids in the mix is preserved within allowable ranges, and the resistance to stripping is increased by 62, 77, 85, and 76%, respectively. Research also shows that incorporating 40% RAP enhances the resistance to moisture by about 5.9%. The addition of 40% RAP reduced the Cantabro loss values by about 2 and 16% for both aging and non-aging samples, respectively. The rutting resistance increased by 50 and 47% for mixes with 40% RAP at 50 and 60°C, respectively. As a result, it became evident that mixtures containing RAP material could be effectively adapted to satisfy the relevant volumetric and performance requirements.

Published: February 2024

Objectives

To mitigate the losses due to fall armyworm (FAW) infestation in maize, chemical pesticides had been the first choice and widely used as an emergency response. However, it comes with attendant health effect. This necessitates the development of plant based effective and safer pesticides. This research investigate response of fall armyworm larvae when they are exposed to crude and partially purified Tithonia diversifolia leaf extract.

Methods

Chemical constituent of the extract was identified using NIST08.LIB library spectra provided by the software on a GC-MS system and FTIR analysis was done using KBr pellet technique with a resolution and scanning speed of 4 cm−1 and 2 mm/s. Dose dependent toxicity assay of T. diversifolia extracts on FAW at different growth stages under controlled environment in laboratory, followed by its effect under phytotron were examined against control and azadirachtin from neem.

Results

The GC-MS of the butanol eluent revealed 20 compounds out of which the major ones being beta-d-glucopyranoside, methyl (15.225 %) palmitic acid, TMS derivative (10.98 %) and hexadecanoic acid, 2-[(trimethylsily)oxy]-, methyl ester (8.75 %). The FT-IR spectroscopic analysis of the butanol eluent of T. diversifolia leaf extract revealed the presence of alcohols, phenols, aldehydes, ketones, alkanes and primary amines. The butanol eluent and crude extract caused 96 % mortality at neonate and first instar FAW larvae.

Conclusions

The toxic and repellant effects revealed by diet bioassay and phytotron experiment respectively suggest that butanol eluent of T. diversifolia leaf extract could be a good and effective target for biopesticide production against FAW.
Cylindrical vector beam multiplexing holography employing spin-decoupled phase modulation metasurface

Published: February 2024

Cylindrical vector beams (CVBs) hold considerable promise as high-capacity information carriers for multiplexing holography due to their mode orthogonality. In CVB holography, phase holograms are encoded onto the wave-front of CVBs with different mode orders while preserving their independence during reconstruction. However, a major challenge lies in the limited ability to manipulate the spatial phase and polarization distribution of CVBs independently. To address this challenge, we propose a spin-decoupled phase modulation strategy by leveraging the propagation and geometric phase of composite phase metasurfaces. By exploiting the polarized Poincaré sphere, we show that CVBs can be decomposed into two circularly polarized components with orthogonal polarization states and conjugate phase distributions. This decomposition enables independent control of the phase and polarization distributions of CVBs by modulating the initial phase and phase difference of these two components. Consequently, two holograms with discrete spatial frequency distributions that carry opposite helical phases are encoded to modulate the wave-front of CVBs by the metasurface consisting of Si nanopillars. This allows for us to achieve successful four-channel CVB multiplexing holography. Benefiting from the non-dispersive nature of geometric phase, this metasurface exhibits a broad operating band spanning the entire visible light spectrum (443 nm–633 nm). These suggest that our proposed method offers comprehensive control over the spatial phase and polarization of CVBs, thereby holding significant potential for advancing their application in holography.

Published: February 2024

In this work, a solid-state electrochemical sensor relying on potentiometric transduction was constructed and optimized to detect Bosentan (BOS) in its pharmaceutical dosage form and human plasma. BOS is useful in pulmonary hypertension management as a nonselective endothelin receptor antagonist. A printed circuit board has been constructed and used as a substrate for microfabricated Cu electrodes. In comparison to a microfabricated control (Cu/ISM) electrode, the sensor potential signal drift was enhanced, and the response time was reduced by using multi-walled carbon nanotubes (MWCNTs) as an ion-to-electron transducer layer. According to IUPAC requirements, the suggested BOS sensors have been electrochemically characterized, and the linear dynamic range is (1.0 × 10−8 to 1.0 × 10−5) M with a limit of detection of 6.28 × 10−9 M and 6.12 × 10−9 M for MWCNT-based sensor (Cu/CNT-NC/ISM) and control sensor (Cu/ISM), respectively. The described sensors have been used successfully to selectively determine BOS in dosage form and human plasma without any pre-treatment steps.
Complexity of Arctic Ocean water isotope (δ18O, δ2H) spatial and temporal patterns revealed with machine learning
Authors: Klein Eric S. , Baltensperger Andrew P. , Welker Jeffrey M.
Published: February 2024

The stable isotope compositions of water (δ18O, δ2H, deuterium-excess) are important tracers that help illuminate the changing Arctic water cycle and how Arctic-sourced water can influence lower latitudes. We present simultaneous boundary layer water vapor and ocean water isotope data that were measured continuously in the western Arctic Ocean. Sea surface water isotopes varied between the shallower continental Chukchi Shelf and the deeper Chukchi Borderlands to the north. The Chukchi Borderlands surface waters were less saline than the offshore Chukchi Shelf, as the Borderlands are influenced by greater sea ice cover and contribution of sea ice melt to surface freshwater. This greater contribution of sea ice melt resulted in lower deuterium-excess (δ2H − 8*δ18O) in surface water values in the deeper Chukchi Borderlands than on the shallower Chukchi Shelf. Additionally, the sea ice melt contributions to freshwater were less prominent than river runoff, but freshwater from both sources decreased substantially below 70 m depth in the Chukchi Borderlands. Our observed water isotope values provided the foundation for producing water isotope maps (isoscapes) based on remote sensing and machine learning which incorporate parameters that can influence ocean circulation and thus water isotopes (e.g., salinity, sea surface temperature, water depth). These isoscapes suggest spatial complexity in the distribution of stable water isotopes in the Arctic, including sharp gradients in the distribution of the isotopes in seawater that were studied. These isoscapes can be improved in future iterations, for example, with the availability of more spatially continuous, remotely sensed oceanic variables or continuous ship-based measurements to use as additional predictors. As a result, the generation of these isoscapes could become a useful tool for understanding the past, present, and future Arctic water cycle in the context of the global hydrologic cycle.

Nickel (Ni+2) doped nanocrystalline Bi2S3 thin films are deposited on the glass substrate from the solutions containing Bismuth Nitrate, Ethylenediamine Tetraacetic acid (EDTA) and Thioacetamide at a bath deposition temperature of 318K. The optical, surface morphological and electrical properties of Ni-doped Bi2S3 thin films prepared at three different doping concentration are investigate by using ultraviolet–visible transmission spectra (UV–Vis), Scanning electron microscopy (SEM), Energy Dispersive X-ray (EDAX) and thermo-e.m.f. techniques. The optical band gap energies are found in between 2.32-2.43 eV. The SEM images show that the prepared films are continuous, dense and distributed over the entire area with good uniformity. The electrical conductivity of the films are in the order of 10-2 Ω-1 m-1 . The films are n-type as determined from the Hot Probe method. Photoconductivity studies reveal that photocurrent increases with the increase in Ni doping concentrations. Due to the absorption of photons, free electron-hole pairs (EHP) are produce.

Silent Protesters or Acceptors? The Reaction of the Russian-speakers to the Removal of the Soviet Monuments in Latvia and Estonia after Russia’s Full-scale Invasion of Ukraine*
Authors: Kuczyńska-Zonik Aleksandra
Published: February 2024

For a long time the approach of the both two Baltic states to the Soviet heritage was formed by: (1) international and bilateral agreements which obliged states to protect monuments and memorial sites of the Soviet Army as well as (2) numerous Russian-speaking community for whom the Soviet statues constitute its cultural identity. The situation has significantly changed due to Russia’s aggressive policy against Ukraine, when the authorities made several attempts to remove the Soviet monuments. This brought some controversies and objections among the Russian-speaking communities in Latvia and Estonia. The paper focuses on the transformation of the national historical narrative toward the Soviet monuments and the processes of the adapting of the Russian-speaking community to the official memory discourse. More specifically, the aim is to explore the ways in which the Russian-speaking residents reacted to the removal of the Soviet monuments. The concept of resistance was applied in order to explore and synthesize the outcomes of the interviews carried out among Russian-speaking communities in Latvia and Estonia. It is argued here that the reconstruction of the public space by shifting the most visual symbol of the victory of the Red Army in the WWII has not induced hot feelings among the Russian-speaking society, and thus, it has not motivated community to take part in the open protest against the removal. Most of the minority representatives stayed passive and silent adapting to the new reality.
La medición efectiva de la participación. Instrumento para la gobernanza ambiental
Authors: Sánchez Taquiba Lina Fernanda , Moreno Soto Guillermo León , Pineda Gómez Hernan Dario
Published: February 2024

El presente artículo tiene como objetivo presentar la propuesta del Índice General de Participación Efectiva (IGPE) como estrategia para medir la calidad de la participación en instrumentos de planificación ambiental. El IGPE se deriva de un sistema relacional de variables asociadas a la participación en asuntos ambientales, compuesto por cuatro dimensiones equiponderadas y 22 variables. Estas dimensiones parten del desarrollo conceptual del Modelo de Gobernanza Territorial Ambiental (GOTA), cuyo objetivo es fortalecer la participación en la gestión ambiental. La medición se llevó a cabo mediante un instrumento de recolección de información primaria tipo censo, en el que se recopilaron 343 encuestas efectivas. Como resultado de la medición, se determina que el IGPE en los cuatro planes analizados se encuentra en un nivel medio. Se observa que la participación y las condiciones para su activación son sólidas en las etapas iniciales de la elaboración de los procesos de planificación ambiental, pero requieren ajustes en los procedimientos que permitan llevar a cabo el control y seguimiento. De esta forma la comprensión de la calidad de la participación le permite a la autoridad ambiental hacer ajustes en los procesos de implementación de los planes trazados.
A comunicação contraintuitiva para além do interesse mercadológico

Published: February 2024

O trabalho teve como objetivo analisar a influência da comunicação contraintuitiva (com inserção de raça e de orientação sexual homoafetiva) para além do interesse mercadológico, englobando a mensuração da reação do consumidor de forma abrangente, nos aspectos ambos implícito e explícito. Elaborou-se um referencial teórico acerca da comunicação mercadológica contraintuitiva, seguido da discussão sobre a inserção das questões de raça e de orientação sexual nela, especialmente frente ao ainda preconceito existente nesse sentido. O método adotado foi uma abordagem hipotético-dedutiva, realizada por meio de dois experimentos. O primeiro, between-subject (n=61) com caráter exploratório, contando com o monitoramento ocular (eye tracker); e, o segundo, within-subject (n=151) com carater explicativo. Como resultado, pôde-se verificar a influência da comunicação contraintuitiva nas reações dos consumidores, mas com valências opostas de acordo com a inserção em questão: de um lado, a raça obteve efeito positivo, enquanto, por outro lado, a orientação sexual teve efeito bastante negativo. Dessa forma, argumenta-se que a aceitabilidade da inserção da questão racial na comunicação mercadológica contraintuitiva até então não se estendeu para a orientação sexual, caminho ainda a ser percorrido. Assim, reforça-se a importância da comunicação contraintuitiva, cujas contribuições se ampliam para além do interesse mercadológico, abarcando também o âmbito social, mais amplo.

Microbial glycerolipids in the global ocean: environmental controls and sinking flux dynamics
Authors:   , Holm Henry C.
Published: February 2024

The composition of glycerolipids from a range of ocean environments were analyzed to better understand the biochemical adaptations and remineralization processes of planktonic biomass. Glycerolipids compose the cell membranes and energy stores of ocean microorganisms. As a biochemical group they present a useful target for tracking a wide range of environmental stress responses. In Chapter 2 of this work, I employ high resolution mass spectrometry to assemble a global dataset of planktonic lipidomes. Using this dataset of samples mostly from the epipelagic, I find that water temperature is a major controlling factor on fatty acid saturation state and hypothesize this derives from known biophysical constraints on cell membranes. I extend this analysis further to investigate links between long-chain essential fatty acids (LCEFA) and temperature. My analysis shows that the abundance of one of these LCEFAs (eicosapentaenoic acid, 20:5 n-3) is well correlated with temperature. Using this relationship, I project temperature-based declines in its abundance due to climate change over the next century. In Chapter 3, using samples from the West Antarctic peninsula, I assess the pigments and glycerolipid compositions of microbial communities within seasonal pack ice floes to gain insights on growth in an extremophile environment. The caloric content of this glycerolipid biomass is additionally calculated to assess its value to higher trophic level consumers within the sea ice ecosystem. I find that glycerolipids’ physical distribution within sea ice core to be calorically dense but highly geographically and physically heterogenous. I additionally show evidence of a new biomarker (fatty acid hydroxy fatty acid triacylglycerols, FAHFA-TAG) which have not been detected before in an ocean system. I further evaluate the possible biochemical sources of these novel biomarkers within sea ice. Lastly, I examine the glycerolipids present in sinking material from two separate studies of carbon flux in the upper mesopelagic. These compositions revealed both sources and remineralization processes influencing lipid carbon. I find evidence that lipid biomass is mostly lost non-selectively from particles, differing from previous reports of selective degradation of lipids. However, I find compositional differences between surface-suspended and sinking material possibly pointing to selection mechanisms at sinking material conception. I use glycerolipids to create a new source metric predicting the relative amounts of sinking material derived from fecal pellets verse aggregates. The findings of this thesis extend our understanding of microbial biochemical adaptations to their environment and reveal controlling factors on glycerolipid cycling in the ocean system.

Project-based learning (PBL) has gained prominence as an effective approach to fostering autonomous learning in Computer Science education. This study investigated the impact of PBL on student learning experiences, involving 169 participants. Data collection employed a closed-ended questionnaire and semi-structured interviews. Quantitative analysis, utilising descriptive and inferential statistics, revealed strong student performance in the Analysis, Planning, Design, and Communication and Presentation phases. However, challenges were noted in the Development and Testing phases, with Project 3 (PRJ303) students exhibiting significantly better performance than Project 1 (PRJ101) and Project 2 (PRJ202) peers. Qualitative analysis of interview data unveiled key themes, including independent learning, team dynamics, guide relationships, real-life project experiences, output orientation, and challenges associated with project-based learning. Despite challenges such as time constraints and team complexities, the study underscores the myriad benefits of PBL, ranging from real-world application and critical thinking development to collaboration and independent learning. The findings advocate for the integration of PBL in university curricula, emphasising the cultivation of skills such as independent learning, teamwork, mentorship, experiential learning, and project management. The positive outcomes observed in students' learning and skill development outweigh the challenges, making a compelling case for the widespread adoption of PBL in Computer Science education.
¿Al margen del conflicto? Apuntes sobre la implementación de Hidroituango en el noroccidente antioqueño (Colombia)
Authors: Fonseca-Reyes Ángela-Jasmín
Published: February 2024

Este trabajo estudia el proceso de territorialización de Hidroituango, el mayor proyecto hidroeléctrico que se construye en Colombia. Se consideran algunos de los efectos socioambientales que produce, así como las dinámicas e interacciones con el conflicto armado interno en el noroccidente de Antioquia, lugar donde se localiza esta mega obra. Para ello, se analiza, desde el enfoque etnográfico, algunos discursos y ciertas prácticas que la empresa promotora del megaproyecto y determinadas instituciones del Estado promueven para justificar su implementación, pese a las fallas, los riesgos y los conflictos que se configuran en el contexto de la planeación y la ejecución de las obras. Más que energía y progreso, Hidroituango ha producido algunos efectos “colaterales” que han contribuido, por un lado, a ampliar y afianzar el poder institucional del Estado en dicho territorio y, por el otro, a consolidar las estructuras socioeconómicas que predominan allí, el conflicto armado y el modelo extractivista.
Multicriteria Analysis for Quality and Reliability in Electrical Systems
Authors:   Universidad Politécnica Salesiana, Aguila Téllez Alexander
Published: February 2024

Electrical Power Systems (EPS) generate, transmit and distribute electrical energy in strict operating ranges. To successfully fulfill these operational phases of the EPS, efficiency, safety, quality, and reliability standards must be established. Each of these standards is associated with variables that have to function within regulated limits. Various authors have proposed many methodologies to optimize these variables to work correctly within the established boundaries. However, most electrical variables present a relationship that can cause unwanted conflicts of interest. It is why more optimization methodologies have recently been proposed that involve the joint analysis of multiple variables (criteria)

Published: February 2024

This study aimed to examine the influence of match location, team quality and players’ nationality on technical and tactical performance indicators in elite goalkeepers. The sample was composed by 87 goalkeepers from the English Premier League during five seasons (from 2011/12 to 2015/16). Twenty-four variables were selected in order to characterize offensive, defensive and disciplinary goalkeeper’s behavior. Different non-parametric test (p<0.05) showed statistically significant differences in all the variables in terms of match location, excepting interceptions, fouls and unsuccesful short distributions. Moreover, statistically significant differences were also found amongst teams’ level in terms of successful passes, goals received inside the box and successful long distribution, both in national and foreign goalkeepers. Finally, only national players exhibit a significant increase in goals received outside-box (top level teams), saves inside-box (intermediate level teams) and unsuccessful long distribution regardless teams quality. The data provided in this study might help goalkeepers’ coaches to modulate the frequency and number of actions performed by goalkeepers during training sessions, and help managers to make decisions when signing goalkeepers according to their nationality.
Silent Processes in Higher Education: Examining Ableism Through an Ability‐Critical Lens
Authors: Leonhardt Nico
Published: February 2024

Universities are regarded as critical institutions that shape society, which on the one hand have a great influence on (successful) social processes, but on the other, are traditionally very privileged and exclusive places of education. Despite various demands to open up to plural perspectives, they are still strongly characterized by powerful, meritocratic, and discriminatory structures, cultures, and orders. (Social) inclusion efforts are always linked to the need to analyze processes of exclusion. This article therefore examines the question: Which ableist practices and culture of silence are revealed in the context of higher education and how can these be linked to the findings of postcolonial studies on the topic of silence? On the one hand, established perspectives (lecturers and students), but above all the perspectives of marginalized and unheard (groups of) people (lecturers with (learning) disabilities) are involved. The results from two group discussions (N = 9) with perspectives from these three different positions are presented to work out implicit and explicit processes of silence. The (power) theoretical reference is the concept of ableism, which is linked with (postcolonial) perspectives on the ideas of “silence” according to Brunner (2017a). This article emphasizes that, in addition to formal access restrictions to university education, there are also implicit barriers oriented towards non‐transparent ableist expectations of ability, which in turn (re‐)produce processes of silence. The case study concerns one German university and shows that formal access to higher education is only one aspect of reducing ableism; above all, it is the creation of transparent structures with regard to set ability expectations, critical‐reflective spaces, and a culture of “unlearning” biographically characterized ableist notions of normality. This article therefore focuses on the connection between ableist experiences and the findings of postcolonial discourses of silencing.
