Gas chromatography coupled to mass spectrometry (GC-MS) has been widely used, and along with other methodologies such as derivatization, is a powerful tool to analyze phytocompounds, including cuticular wax components. The loss of structural information upon fragmentation of waxes makes it difficult to interpret and identify the GC-MS mass spectra of these compounds with the traditional methods, as digital libraries. Therefore, as a new complementary alternative to traditional methods of identifying aliphatic acyclic lipids based on mass spectra, we present the new software WaxAlly in this technical note. WaxAlly is a new software created based on simple algorithms, enabling the rapid recognition by the user of eight aliphatic acyclic lipid classes, including alkanes, alkenes, aldehydes, ketones, esters, and TMS derivatives of free fatty acids, primary and secondary alcohols, and their homologues with carbon chains varying between 10 and 100 carbons. Additionally, the WaxAlly software provides a section for data organization, internet comparison to NIST and PubChem databases, and academic information about mass fragmentation of acyclic lipids. The software has proven to be a very useful complementary technique in identifying plant wax lipid homologues, and new fragmentation patterns of lipid classes can be added in the future to improve the program.

ABSTRACT: Graphic communication projects begin with a strategic phase whose objective is to conceptualize a sensory universe that will be associated with the product or brand for which the project is developed. The objective is to emotionally connect the brand or product with the user. In this process, the "performativity" potential of images is used to define and communicate complex emotional qualities that are difficult to express through verbal language. Mostly, images are searched on the Internet and classified through hegemonic iconographic and iconological patterns. This article proposes to activate a critical look at the hybrid co-creation process that is generated between human and machine in the search for images on the net. Analyzing the agency of the non-human in this procedure will allow us to establish if the creative and methodological processes used contribute to establish and perpetuate a prevailing visual hegemony, or if they help to open fissures in its structure.

RESUMEN: Los proyectos de comunicación gráfica se inician con una fase estratégica cuyo objetivo es conceptualizar un universo sensorial que irá asociada al producto o marca para la cual se desarrolla el proyecto. El objetivo es conectar emocionalmente la marca o producto con el usuario. En este proceso se recurre al potencial de “performatividad” de las imágenes, para definir y comunicar cualidades emocionales complejas, difíciles de expresar a través del lenguaje verbal. Mayoritariamente, las imágenes se buscan en internet y son clasificadas mediante patrones iconográficos e iconológicos hegemónicos. Este artículo propone activar una mirada crítica sobre el proceso de co-creación híbrido que se genera entre humano y máquina en la búsqueda de imágenes en red. Analizar la agencia de lo no-humano en este procedimiento permitirá establecer si los procesos creativos y metodológicos usados contribuyen a establecer y perpetuar una hegemonía visual imperante, o si ayudan a abrir fisuras en su estructura.

RESUMEN En el contexto actual, la transformación digital se ha convertido en un factor fundamental para el cambio de la matriz productiva en Ecuador. Esto se debe a que el mundo está siendo cada vez más digital y las empresas necesitan adaptarse a esta nueva realidad para seguir siendo competitivas en el mercado nacional e internacional. Sin embargo, a pesar de los esfuerzos del gobierno ecuatoriano por impulsar la transformación digital, todavía existen obstáculos que limitan su implementación de manera eficiente y efectiva. Uno de ellos es el insuficiente conocimiento sobre el tema y sobre sus beneficios para la práctica social. Muchas empresas todavía no han adoptado las tecnologías digitales en sus procesos y actividades. Por otro lado, existen barreras como la falta de acceso a internet en algunas zonas rurales y la falta de capacitación y formación en habilidades digitales. El objetivo de este estudio es ofrecer un análisis de los niveles de interdependencia intersectorial en el contexto de la matriz productiva de Ecuador, identificando los principales desafíos, fortalezas y oportunidades. De esta manera se podrán proponer recomendaciones para la integración efectiva con la transformación digital. La metodología consistió en revisar la literatura sobre la transformación digital y su integración a la matriz productiva de Ecuador. También se recopiló información de estudios y datos estadísticos sobre la adopción de tecnologías digitales en el país.

ABSTRACT In the current context, digital transformation has become a key factor for changing the productive matrix in Ecuador. This is because the world is becoming increasingly digital and companies need to adapt to this new reality to remain competitive in the domestic and international markets. However, despite the Ecuadorian government's efforts to promote digital transformation, there are still obstacles that limit its efficient and effective implementation. One of those obstacles is the insufficient knowledge about the subject and about its benefits for social practice. Many companies have not yet adopted digital technologies in their processes and activities. On the other hand, there are barriers such as the lack of access to the internet in some rural areas and the lack of training and skills in digital skills. The objective of this study is to offer an analysis of the levels of intersectoral interdependence in the context of Ecuador's productive matrix, identifying the main challenges, strengths and opportunities. In this way, recommendations can be proposed for effective integration with digital transformation. The methodology consisted of reviewing the literature on digital transformation and its integration into Ecuador's productive matrix. Information was also collected from studies and statistical data on the adoption of digital technologies in the country.

ABSTRACT The non-consensual dissemination of sexual content, a type of digital violence that is favored through anonymity, massiveness, and impunity, affects women differentially. Facing this difficult context, Colombia has enormous challenges in supporting women who are at risk or face this sort of violence. The current regulatory development is precarious and there is no criminal offense statement or specific public policies that serve to prevent and to support these cases.

RESUMEN La difusión no consentida de contenido sexual es un tipo de violencia digital que afecta de manera diferencial a las mujeres, favorecido por el anonimato, la masividad y la impunidad. Ante este difícil panorama, Colombia cuenta con enormes retos frente al acompañamiento de las mujeres que están en riesgo o enfrentan estas violencias, teniendo en cuenta que el desarrollo normativo es precario y no existe un tipo penal específico con enfoque de género o políticas públicas específicas que sirvan para prevenir y para acompañar estos casos.

Resumen El fenómeno migratorio en México ha cobrado relevancia debido al aumento del tránsito de centroamericanos por el país para llegar a Estados Unidos a cumplir el sueño americano. En este artículo se identifican los imaginarios y fuentes de información de los migrantes respecto a su trayectoria y destino final. Se llevaron a cabo 60 entrevistas en una casa del migrante en la ciudad de Monterrey a participantes provenientes de Honduras, El Salvador, Guatemala y Nicaragua. Las conclusiones demuestran imaginarios romantizados, cuyos fundamentos son primordialmente fuentes interpersonales (otros migrantes y conocidos que ya han hecho el viaje) y fuentes mediáticas (televisión, cine, Internet y periodismo). Desde una perspectiva sociológica y de ciencias de la información, este caso de estudio revisa la idea de los imaginarios como parte elemental en la toma de decisiones de los migrantes que arriesgan sus vidas para alcanzar destinos meta.

Abstract The topic of migration in Mexico has gained relevance since there has been a significant increase of Central American migrants traveling through the country towards the United States, to achieve the American dream. This article identifies the imaginaries and sources of information of migrants regarding their transit and final destination. Sixty people were interviewed in a local shelter of the city of Monterrey with participants from Honduras, El Salvador, Guatemala, and Nicaragua. The conclusions show romanticized imaginaries, founded primarily on interpersonal sources (other migrants and acquaintances who have made the trip) and media sources (television, cinema, the Internet, and journalism). From a sociological and information science perspective, this case study reviews the idea of imaginaries as a fundamental part in the decision making of migrants who risk their lives in order to reach target destinations.

This paper aims to discuss the different activist strategies that vegans use on social media platforms, especially Facebook and YouTube, in Brazil. The popularization of veganism in the country is directly linked to the arrival of the internet and the emergence of so-called “virtual communities” that have strengthened their own political actions expressed through food activism. Therefore, when analyzing veganism as a social movement, it is important to understand how it uses social media platforms in different ways to organize, act, engage and resonate with styles, identities, consumer goods and active political organizations, capable of competing in the global market of the traditionally dominant value chain. The methodologies were a literature review and a content analysis of data collected from November 2021 to April 2022 on two social media platforms: Facebook and YouTube. In the first, a netnography was carried out in two online groups. On YouTube, data was collected using the online tool YouTube Data Tolls, which searched for videos published during the aforementioned period with references to vegan issues, and created a network of the main channels that shared this content. By analyzing this data, it was possible to identify how the vegan movement has strengthened in Brazil through the use of and active engagement with social media, which contributes to the consolidation of lifestyles in terms of the production, circulation and consumption of material and symbolic goods.

O presente trabalho tem como objetivo discutir as diferentes estratégias de ativismos que os veganos utilizam em plataformas de mídias sociais, especialmente Facebook e YouTube, no Brasil. A popularização do veganismo no país está diretamente ligada as chegadas da internet e à emergência das chamadas "comunidades virtuais" que fortaleceram ações políticas próprias expressas pelo ativismo alimentar. Diante disso, ao analisar o veganismo enquanto um movimento social, torna-se importante compreender como o mesmo utiliza, de maneiras diferentes, plataformas de mídia sociais para organizar, agir, engajar e repercutir estilos, identidades, bens de consumo e organizações políticas ativas, capazes de disputarem o mercado global da cadeia de valores tradicionalmente dominantes. As metodologias foram as revisão bibliográfica e uma análise de conteúdo de dados coletados, durante o período de novembro de 2021 a abril de 2022, em duas plataformas de mídias sociais: Facebook e YouTube. Na primeira, foi realizada uma netnografia em dois grupos online. No YouTube, uma coleta de dados a partir da ferramenta online YouTube Data Tolls em que foram buscados vídeos publicados, durante o período já mencionado, com referências a temática vegana, e criada uma rede dos principais canais que compartilharam esse conteúdo. A partir da análise desses dados, foi possível identificar como o movimento vegano se fortaleceu no Brasil a partir do uso e engajamento ativo nas mídias sociais, que colaboram para a consolidação de estilos de vida em termos de produção, circulação e consumo de bens materiais e simbólicos.

RESUMO O objetivo deste artigo é contribuir para o debate sobre raça e etnia em meio às organizações de extrema-direita na internet, usando Portugal como estudo de caso. A questão principal é analisar como a extrema-direita em Portugal, apesar de seu pequeno número de grupos, abrange um enorme campo de estruturas mundiais. Existem, basicamente, dois eixos ideológicos principais altamente opostos entre si. Um eixo afirma que Portugal pertence a um universo etno-europeu branco que visa um Portugal amalgamado a um continente europeu no qual os brancos deveriam ser a maioria incontestável, se não toda a população. Seus seguidores são influenciados por escolas de pensamento da Europa e dos Estados Unidos. O outro eixo afirma que o povo português é especialmente propenso à miscigenação com europeus não brancos. Este eixo visa um Portugal amalgamado com seu antigo império nos trópicos e baseia seu ideal em pensamentos surgidos no Brasil. Concluo que ambas as linhas ideológicas dividem a direita grupuscular portuguesa e dão um tom muito particular à metapolítica. extremadireita extrema internet caso grupos mundiais Existem basicamente si etnoeuropeu etno incontestável população Unidos Brasil metapolítica

ABSTRACT The aim of this article is to contribute to the debate on race and ethnicity amidst Far-right internet organizations by using Portugal as a case study. The main issue is to analyze how the Far-right in Portugal, despite its small number of groupings, encompasses a huge overarching field of worldframes. There are, basically, two main ideological axes highly opposed to each other. One axis states that Portugal belongs to a white ethnoeuropean universe. It aims at a Portugal amalgamated to a European continent in which whites should be an undeniable majority, if not all its population. Its followers are influenced by schools of thought from Europe and the USA. The other axis states that the Portuguese people are especially prone to miscegenation with non-white Europeans. It aims at a Portugal amalgamated with its former Empire in the tropics and bases its ideal on thoughts emerged in Brazil. I conclude that both ideological lines cleave the Portuguese groupuscular right and give a very particular tone to Metapolitics. Farright Far study groupings worldframes basically universe majority population USA nonwhite non Europeans Brazil Metapolitics

INTRODUCTION: The COVID-19 pandemic brought about a global crisis in higher education, where students were required to transition to emergency remote teaching (ERT). This study explored students' experiences of online assessments and feedback during the pandemic to inform future practice. METHODOLOGY: This study utilised a descriptive cross-sectional quantitative design with purposeful sampling to describe student's experiences of online assessments. Data were collected from occupational therapy students in 2022. The Assessment Experiences Questionnaire was sent to all eligible participants (n=166). Data were analysed using SPSS version 28. RESULTS: Students reported that 'tackling' assignments made them apply their learning more deeply (79.75%; n=63). More than half of the students learned more from doing assignments than studying course material (61.25%; n=49). Majority of students felt they did not receive timely feedback through online assessments (67.5%, n=54)( which impacted their learning. More than half of the students use feedback in preparation for assignments (56.25%; n=45), hence timely and quality feedback is needed. CONCLUSION: Occupational therapy students had a positive experience of online assessments; however, the transition was challenging. It is recommended for lecturers to consider the challenges of online assessments, the number of assessments and timely feedback for an effective online learning process. IMPLICATIONS FOR PRACTICE • For online learning to be effective, relevant and timely access to resources and support systems are required. These include internet access, resources like laptops and smartphones which facilitate engagement with remote learning. • The provision of institutional and academic support can positively influence students' experiences of online learning. • Timing and quality of feedback is essential to the online learning experience. Delayed feedback can negatively impact learning, emphasising the importance of timely feedback to aid student growth and improved learning outcomes. • Students' experiences and perceptions of how they receive feedback change over time. Thus, personalised feedback focusing on improvement rather than comparison to peers should be emphasised in the learning environments to which they are exposed. • The importance of effective time management in students is emphasised for online learning and students need to be equipped with these skills for this mode of learning.

Abstract From the perspective of critical animal studies, this text explores the political potential of photographs and films depicting “horror” or containing strong representations of animal pain and suffering. These images are disseminated through social networks on the Internet by various organizations and individuals interested in promoting veganism. This exploration is guided by concepts and reflections present in the works of Didi-Huberman, Rancière, and Sontag, each approaching the political role of images in genocidal historical processes from different perspectives. In doing so, this study critically engages with notions of animal pain and suffering, and connects some of these arguments with animal exploitation. The aim is not only to shed light on questions regarding the political function of images and the gaze in the human-animal relationship, but also to analyze the common structures of thought underlying both material and symbolic violence directed at both human and non-human animals.

Resumen Desde el enfoque de los estudios críticos animales, el texto aborda el potencial político de las fotografías y los audiovisuales del “horror”, o con un fuerte contenido de dolor y sufrimiento animal, difundidas a través de redes sociales en internet por las diversas organizaciones e individuos interesados/as en promover los veganismos, a la luz de ciertos conceptos y reflexiones presentes en Didi-Huberman, Rancière y Sontag, quienes, desde diferentes perspectivas, se ocupan del lugar político de las imágenes en procesos históricos genocidas. Para esto me acerco críticamente a las nociones de dolor y sufrimiento animal y entrecruzo algunos de los argumentos citados con el campo de la explotación animal, con el fin de no solo de iluminar las preguntas sobre el rol político de las imágenes y la mirada en la relación humano-animal, sino también problematizar aquellas estructuras comunes de pensamiento a la base de la violencia material y simbólica tanto hacia los animales humanos como los no humanos.

Students' research, interactivity, experiences, and exposure have increasingly become important indicators of quality in higher education, however these expectations declined during COVID-19 pandemic. While studies have been conducted on postgraduate students' experiences during their studies, there is lack of empirical evidence on their experiences during COVID-19 pandemic, specifically at open distance learning institutions (ODLs). To bridge this identified gap, qualitative exploratory research was conducted to explore the experiences of postgraduate students registered in master's and doctoral programmes at the Department of Health Studies, University of South Africa, during the pandemic. Non-probability purposive sampling was used. Online interviews via Microsoft Teams were used for data collection. The interviews were recorded and the data obtained were analysed thematically. Findings revealed both positive and negative experiences. Anxiety, exhaustion and frustration due to sickness, death of family members, poor communication from the university, inadequate resources and poor internet access affected students' studies. Some participants reported lack of supervisory communication and support, while others applauded the continuous support of their supervisors and the university's improvement of its electronic communication linkages. Microsoft Teams was newly adopted. Working from home also gave them an opportunity to accelerate their studies. In conclusion based on the findings the researcher recommended that the university continue to improve academic support and address the mental health of students to prepare them to accept current and future unforeseen circumstances positively. Strengthening collaboration with national and international partners to enhance continuous online communication between the university and the students should also be considered.
