description: A dirofilariose é uma parasitose que afeta principalmente os cães, podendo também acometer outros animais, e acidentalmente os humanos. É causada pelo nematode Dirofilaria immitis transmitido por vetores culicídeos. A doença é grave devido à elevada virulência do parasita para alguns animais e também pelo seu potencial zoonótico. Esta doença tem distribuição cosmopolita e tem vindo a ser marcada pelo aparecimento de animais infetados em regiões onde o agente não tinha previamente caráter endémico. Em Portugal a dirofilariose é endémica, sendo o território nacional considerado com condições favoráveis para o desenvolvimento dos vetores.


Do ponto de vista da saúde humana, aproximadamente 60% dos indivíduos infetados são assintomáticos, e a presença de um nódulo pulmonar que não provoca normalmente sinais ou sintomas pode apenas ser detetado através de exames por imagem. Quando presentes, os sintomas são inespecíficos e incluem: febre, dor torácica, hemoptise, tosse, dispneia, fadiga, síncope e perda de peso.


Os fatores que contribuem para a expansão desta parasitose são principalmente as alterações climáticas, que podem favorecer áreas de maior concentração dos vetores, o desconhecimento sobre a doença, os fatores socioeconómicos que limitam o acesso à profilaxia, a presença de hospedeiros silvestres em áreas urbanas e animais portadores sem possibilidade de tratamento.


Este estudo teve início em 2022 e deu origem a uma dissertação de mestrado, em que foi descrito um estudo epidemiológico e fatores de risco da dirofilariose canina no concelho de Leiria. Pretende-se com a continuidade do projeto abranger outras áreas endémicas e não endémicas da doença, atualizar os dados sobre a prevalência e sensibilizar os médicos veterinários para o diagnóstico através das técnicas recomendadas.

description: Customer loyalty programs are a marketing instrument that have been used for decades, but are being made available to more and more companies due to newer technologies. However, it is proven that a lot of them fail or do not yield the desired results. Monitoring the programs performance is a good way to make sure that the previously set objectives can be reached or detect problems. This can be a problem, especially for small companies, as the resources for the monitoring are limited and need to be used effectively. In this thesis, I want to find out how monitoring and tracking certain metrics could help reach the objectives, focusing on App-based customer loyalty programs for small businesses. In order to do this I will briefly look at why a loyalty program is implemented in the first place and how different programs work. Then I am going to summarize which metrics can be measured and what counter actions can be taken when the goals are not met. I propose a set of questions in order to determine which metrics should be tracked for each individual company. Lastly I conducted a survey with companies about how they see the importance of some of the metrics and their available time to analyze the system. Most of the hypotheses could not be accepted, but some derived insights could be gathered after more variables were taken into account. Even though the significance of some findings could not be statistically proven, they can be seen as a starting point to conduct further investigations with more resources.

description: The main objectives of this master thesis is to both understand the actual start-up environment in Austria; its main advantages and triggers as well as the most important barriers and set-backs that they face in both the creation process and the developing process. Once the context is cleared up, then the thesis is focused on developing an Opportunity Assessment Plan for six potential business ideas until finally one of the ideas is chosen to be developed with a full business plan via a simple scoring system. 66% of the business ideas are characterized by either internet connection portals or technology driven developments which is very coherent with Austrias start-up creation in the last decade. Moreover, once the idea is well developed in the business plan, the financial structured analysis will give the final conclusion to the business development and creation. The originality of this master thesis relies on the development of the idea while including the financial, cultural and economic environment of Austria.
Estudo da fauna parasitária em capivaras (Hydochoerus hydrochaeris Linnaeus, 1766) no Brasil

description: As capivaras (Hydrochoerus hydrochaeris) são consideradas os maiores mamíferos roedores do mundo. Distribuem-se por toda América do Sul, com exceção do Chile. No Brasil ocorrem em todos os biomas, desde que o ambiente tenha os fatores paisagísticos como: corpo d’água para funções de termorregulação e locomoção, fragmento florestal para proteção e abrigo, e gramíneas ou áreas de campo para alimentação. São encontradas tanto em ambientes naturais quanto em áreas antropizadas. Devido à sua facilidade de adaptação em ambientes urbanizados, pela ausência de predadores naturais, oferta de alimento e alta prolificidade, em algumas áreas urbanizadas pode ocorrer um aumento considerável da população de capivaras, influenciando no contato direto com humanos e animais domésticos. 


A frequente interação de capivaras com humanos torna-se preocupante do ponto de vista da saúde pública, porque estes animais são hospedeiros de uma elevada gama de parasitas, sendo muitos destes agentes zoonóticos. A Febre Maculosa Brasileira é causada pela bactéria Gram-negativa intracelular obrigatória Rickettsia rickettsii que é transmitida pela carraça do género Amblyomma, sendo esta uma das doenças de maior preocupação devido a ocorrência de diversos casos em ambientes urbanizados no Brasil, alguns destes resultando em morte. Outros parasitas também foram observados em capivaras, como Fasciola hepatica, Taenia spp., Strongyloides spp., Trichuris spp., Eimeria spp., Toxoplasma gondii, Trypanossoma cruzi e Leishmania infantum, entre outros. Alguns destes parasitas, além de possuírem potencial zoonótico, podem infectar capivaras de cativeiro ou de vida livre, elevando o risco para a conservação deste animal e para a saúde pública.


Este projeto tem como objetivo estudar a fauna parasitária em capivaras, correlacionar com fatores ambientais e estabelecer os fatores de risco de ocorrência de zoonoses.

description: Eukaryotic cell motility involves a complex network of interactions between biochemical components and mechanical processes. The cell employs this network to polarize and induce shape changes that give rise to membrane protrusions and retractions, ultimately leading to locomotion of the entire cell body. The combination of a nonlinear reaction-diffusion model of cell polarization, noisy bistable kinetics, and a dynamic phase field for the cell shape permits us to capture the key features of this complex system to investigate several motility scenarios, including amoeboid and fan-shaped forms as well as intermediate states with distinct displacement mechanisms. We compare the numerical simulations of our model to live cell imaging experiments of motile {\it Dictyostelium discoideum} cells under different developmental conditions. The dominant parameters of the mathematical model that determine the different motility regimes are identified and discussed.
Emergent zoonotic fish-borne parasitoses in Portugal

Year: 2024

description: Portugal has the highest per capita consumption of fishery products in the European Union and is a top-ranking country even in a global scale. The recent introduction of exotic eating habits, mainly raw and marinated culinary specialties, has raised the risk of previously irrelevant zoonotic diseases, particularly parasitic ones. Therefore, parasites represent one of the most important hazards in fishery products not only due to the wild nature of its hosts (most fishery products are originated from wild fish stocks) but also the lack of awareness among consumers regarding its risks.


In the past few years, some human zoonotic cases caused by the consumption of parasitized fish have been reported in Portugal for the first time. Apart from the risk of infection by live specimens, some fish parasites are also known to cause potentially fatal allergic reactions in human patients, while others exhibit carcinogenic potential.


Certain exotic zoonotic fish parasites are known to be geographically specific and require particular environmental conditions and hosts to complete their life cycles, which has prevented their introduction in Portugal. However, global warming and the growing exchange of goods and people marked by globalization and the recent influx of displaced people and animals may swiftly change that assumption. These continuous transformations keep molding our reality and, therefore, constant monitoring is required.


As such, this communication aims to sensitize the academic community and particularly veterinary students for the topic of emergent zoonotic fish parasitoses, the relevance of its characterization and ultimately its prime importance to food safety and public health.

Utilizaram-se dados da Pesquisa Industrial Anual (PIA) de 2005 do IBGE. Aplicou-se a análise envoltória de dados (DEA) orientada ao insumo, tendo-se a receita líquida do setor como produto e como insumos o total do custo das operações industriais (COI) e as remunerações do setor (SRO). Dos 18 estados analisados, São Paulo é o mais eficiente e Santa Catarina, o mais ineficiente. Outros 11 estados são tecnicamente ineficientes, de forma que 6 devem, no curto prazo, buscar a camada 1; 5 a camada 2; e 1 (Santa Catarina) a camada 3. Verificou-se que nas Regiões Sul e Sudeste o SRO é a principal causa de ineficiência, enquanto que para as demais Regiões é o COI.--------------------------------------------------We proposed, in this article, a search of intermediate goals into iso-efficiency layers, so that the Food and Beverage Industry (SFPAB) of each Brazilian State can reach, in a gradual way, a higher level of technique efficiency. The IBGE’s 2005 Annual Industrial Research (PIA) data was applied to an efficiency analysis, Data Envelopment Analysis (DEA), guided to the input. In this analysis, we assume the industry liquid revenue as output and as inputs the total cost of industrial operations (COI) and the industry remunerations (SRO). São Paulo State is the most efficient of the 18 States analyzed and Santa Catarina State is the most inefficient from them. Other 11 States are technically inefficient, so that 6 States owe to seek the layer 1 in the short-run; 5 the layer 2; and 1 (Santa Catarina State) the layer 3. It was verified that in the South and Southeast Region SRO is principal inefficiency cause while it is COI for the other Regions.

description: In this qualitative multiple case study, I explored the identities of students in a Lengua Inglesa major in a northern Mexican university. By applying a theoretical framework of imagined communities (Anderson, 1991; Norton, 2000; Wenger, 1998), I examined the ways in which the identities of these students are negotiated as the students move within and across linguistic and cultural communities. I attempted to answer four main questions: What are the students’ imagined communities at the beginning of the program? What are the students’ imagined communities towards the end of the program? What may be the impact on students’ identity/imagined communities of receiving instruction in a foreign language while surrounded by their native language and culture? The study took place at a Lengua Inglesa major that operates within the School of Humanities at a university located near the U.S.-Mexico border. Data collection took place from February through April 2006, and consisted in two rounds of semi-structured interviews with five first-year students, four fourth-year students, as well as four full-time professors and three sessional instructors. I used an open-ended interview guide to facilitate the interview process. Since all of the participants were fluent in both Spanish and English, as I was, they were given the choice of conducting the interview in either language. The interviews were digitally recorded and subsequently transcribed, coded, and analyzed thematically. The findings of this study suggest that students imagine a Lengua Inglesa degree will provide them with linguistic resources and knowledge necessary to access a wide range of imagined communities both within and beyond national boundaries. This vision seems to be reinforced by the futures that the Lengua Inglesa professors envision for Lengua Inglesa graduates, which includes the adoption of an identity as English-language-professionals. As part of this identity, Lengua Inglesa students are expected to develop professional skills and a strong work ethic that allows them gain access to a wide range of professional and academic imagined communities. This identity helps establish clear boundaries between Lengua Inglesa and surrounding learning communities that the Lengua Inglesa community perceives as having impoverished futures.

description: The topic of this thesis is the relationship between the business models (BMs) of the firms which create artificial intelligence (AI) solutions in complex digital platform ecosystems and their success in profiting from innovation. The AI technology endows machines and processes with human-like communication and perception abilities, and with the capacity to learn from data and optimize at scale not accessible to humans. The AI technology solutions depend on the underlying digital solutions for access to data and computation resources. An AI solution is a digital product offered over a complex platformbased architecture that combines internal innovation with complementary assets some of which are controlled by other companies. According to theory, external complementary assets have substantial impact on how much a firm can profit from innovation. How key assets are allocated and controlled is part of a firms business model. The aim of the thesis is to systematize BMs of AI innovators into a typology of patterns and to analyze how AI innovators of different types profit from their innovation. The thesis adopts the qualitative content analysis of the information acquired in e-research. The particular focus of this study is on the AI innovators who are registered in the CrunchBase database, and who were acquired by other companies. The BM information is extracted from the websites of firms and the information about the acquisition. The hypotheses are: H1) Based on the collected data, a small number of distinct patterns can be identified; H2) The motivation for acquisition is to improve not only operational capabilities but also higher-order transformative capabilities, H3) The existing theory can be applied to BM patterns to reason about the emergence of the dominant design. The result of the thesis is a typology of BM patterns and the underpinning analysis framework. The research prospects include verifying the typology and the analysis framework in both case studies and a larger sample of companies and conducting quantitative studies based on surveys and interviews with experts and managers to verify the findings.

description: The ability to design the scattering properties of electromagnetic structures is of fundamental interest in optical science and engineering. While there has been great practical success applying local optimization methods to electromagnetic device design, it is unclear whether the performance of resulting designs is close to that of the best possible design. This question remains unsettled for absorptionless electromagnetic devices since the absence of material loss makes it difficult to provide provable bounds on their scattering properties. We resolve this problem by providing non-trivial lower bounds on performance metrics that are convex functions of the scattered fields. Our bounding procedure relies on accounting for a constraint on the electric fields inside the device, which can be provably constructed for devices with small footprints or low dielectric constrast. We illustrate our bounding procedure by studying limits on the scattering cross-sections of dielectric and metallic particles in the absence of material losses.

description: Objetivos: O histiocitoma cutâneo canino (HCC) é uma neoplasia benigna comum em cães jovens, com origem nas células de Langerhans. A predisposição racial deste tumor não é clara. Este estudo tem como objetivo, a caracterização epidemiológica destes tumores em Bulldogs Franceses (BF) e compará-los com as outras raças, relativamente às variáveis sexo, idade, tamanho, localização anatómica, diâmetro e distribuição geográfica.


Materiais e Métodos: Estudo retrospetivo com base na população de casos de tumores cutâneos diagnosticados no laboratório DNAtech de Janeiro de 2020 até Fevereiro de 2022.


Resultados: Foram identificados um total de 359 HCC. A maioria dos casos pertenciam a machos (58.5%) e 50% dos casos ocorreram até aos 2 anos de idade. A raça com maior número de casos foi o BF com 24% do total das amostras. A face e o membro anterior foram os locais mais comuns de HCC. Os resultados estatísticos mostraram uma relação entre a raça BF e a face. Os machos apresentaram lesões maiores comparativamente às fêmeas e as lesões na região perianal eram maiores do que as restantes lesões. Os machos da raça BF e Boxer apresentaram maior probabilidade de desenvolver um HCC do que em fêmeas e nas restantes raças.


Conclusão: A célula de Langerhans é uma célula apresentadora de antigénio responsável pelo controlo das respostas imunológicas da pele. Perceber o porquê de uma maior prevalência de um tumor destas células nos BF, poderá abrir caminho a outras linhas de investigação que não se resumem à oncologia.

description: Uma análise do programa de eletrificação rural no estado de Pernambuco entre os anos de 1998 e 2002 mostra que a demanda total por energia elétrica não acompanhou a expansão da oferta via ampliação da cobertura de atendimento. Com efeito, estudos sobre políticas de eletrificação e seus efeitos no bem-estar e na estrutura produtiva das comunidades atendidas não são freqüentes no país e muito raros no Nordeste. A eletrificação ainda é vista pura e simplesmente como panacéia para a pobreza rural, sem se empregar ações complementares de educação para o consumo e ações de melhoria na estrutura produtiva das novas populações atendidas. A chegada da rede de energia elétrica ou outras fontes de energia a áreas remotas é fortemente desejável – isto está fora de questão – mas sem políticas complementares, os resultados podem ser pífios. Dados de fontes primárias da concessionária de eletricidade de Pernambuco, CELPE, apontam para uma aparente incongruência: embora o número de domicílios atendidos tenha aumentado substancialmente, a demanda conjunta permaneceu praticamente constante (diferentemente do que aconteceu em outros estados cuja demanda cresceu de modo compatível à expansão da oferta). Neste artigo, serão apontadas hipóteses explicativas, como a falta de preparo do morador rural para a utilização da energia adicional e a utilização dos programas de energização para finalidade política. Resta latente um grande potencial de aproveitamento de energia no interior, mas a sua ativação de modo a catalisar o desenvolvimento rural passa pela necessidade de políticas complementares e estruturais de curto, médio e longo prazo.

description: The expectations of educators’ roles and professional practices have changed considerably due to emerging societal trends and external factors. This paper proposes a structured way to capture and present these changes. We have conducted a literature review of 70 academic and grey publications, an in-depth analysis of 50 existing frameworks, standards and profiles, and a validation workshop with policymakers, researchers and educators. As a result, we have developed a meta-model called READY (Reference Model for Educators’ Activities and Development in the 21st centurY) that focuses on practices which are relatively new or are receiving increased attention in guiding educators’ professional development. READY comprises six-plus-one domains of professional activity, twenty-two professional practices, and seventy-three descriptors of how the practices can be implemented. As a reference model, READY can support educators in identifying development needs and updating their professional practices for responding to the changing needs of society.

We find that there are strong signatures in these networks of topography and use patterns, giving the networks shapes that are quite distinct from one another and from non-geographic networks. We offer an explanation of these differences in terms of the costs and benefits of transportation and communication, and give a simple model based on the Monte Carlo optimization of these costs and benefits that reproduces well the qualitative features of the networks studied.

description: This master thesis argues that European rail freight is increasingly coming under pressure due to fundamental shifts in market demand, competition and technology. These forces are ever more nagging especially at national incumbents longtime key competitive advantages against road transportation: Price competitiveness in long-distance transports, capacity, dependability and eco-friendliness. To counter this trend, the master thesis argues that national incumbents need to find new answers to the key question of what their unique value proposition and competitive edge will be in a world where road transportation is gradually more becoming like rail freight. For doing so, it is argued that national incumbents need to increase their innovation performance capability. This will above all be achieved by four measures: (1) By identifying, formulating and executing on clear innovation targets. (2) By designing and implementing a comprehensive yet standardized innovation process. (3) National incumbents have to set up pertinent organizational structures that strengthen exploration, agility and organizational learning. (4) Cultural factors that prevent a company from reaching its full innovation potential have to be identified and remedied appropriately. The master thesis studies and discusses general principles, models and frameworks that serve as a foundation for improving innovation performance. It applies these concepts to Rail Cargo Group, one of Europes leading rail freight operators, with the ultimate aim of giving policy recommendations to Rail Cargo Group on how to enhance its innovation capabilities. In view of this: Even though the master thesis covers a specific company, the methods of analysis chosen as well as the conclusions drawn will be of interest to other rail freight companies as well.
Birth environment of circumbinary planets: are there CBPs on the inclined orbits?

description: The inclination distribution of circumbinary planets (CBPs) is an important scientific issue. It is of great significance in estimating the occurrence rate of CBPs and studying their formation and evolution. Although the CBPs currently discovered by the transit method are nearly coplanar, the true inclination distribution of CBPs is still unknown. Previous researches on CBPs mostly regarded them as an isolated binary-planet system, without considering the birth environment of their host binaries. It is generally believed that almost all stars are born in clusters. Therefore, it is necessary to consider the impact of the close encounters of stars on the CBP systems. This article discusses how the close encounters of fly-by stars affect the inclination of CBP. Based on extensive numerical simulations, we found that CBPs in close binary with a spacing of about 0.2 au are almost unaffected by star fly-bys. Their orbits remain coplanar. However, when the spacing of the binary stars is greater than 1 au, the 2-3 fly-bys of the intruding star can excite a considerable inclination even for the CBP near the unstable boundary of the binary. For the planets in the outer region, a single star fly-by can excite an inclination to more than 5 degrees. Especially, CBPs in near polar or retrograde orbits can naturally form through bianry-star encounters. If close binaries are born in open clusters, our simulations suggest that there may be high-inclination CBPs in binaries with spacing > 1 au.

description: Artificial intelligence (AI) teaching is becoming an increasingly popular topic among educators and researchers. Its importance in the research field stems from its ability to process and analyze large datasets, identify patterns and trends, provide new insights, and automate complex tasks. Educational policies make serious plans to develop teachers’ professional competencies and implement many in-service training. Concerns about the accuracy of the outputs produced by AI systems arise due to inaccuracies or biases that may be present in the data on which they are trained. The aim of the study was to identify teachers’ views on their digital skills in research studies using AI tools. In this study, a qualitative research method was used to find answers to the research questions. The data of the study were collected through a semi-structured interview form. The obtained data were analyzed with content analysis. The study group consisted of 14 (female=8; male=6) secondary school teachers.
The findings of this study comprehensively examine the experiences of secondary school teachers using generative AI tools. The findings obtained in terms of opportunities and barriers reveal the importance of broad policy changes and supportive education programs to support the integration of technology in education. In addition, future expectations emphasize the need to strengthen the technological infrastructure and provide comprehensive training programs for teachers.

An innovative response to enhance Native American educational success and advancement in higher education
Creators: name: Montes, Claudine A.
Publisher: name: University of British Columbia
Year: 2010

description: This thesis argues the need for major change in higher education options currently available to Native American students in the United States. Universities and Tribal Colleges represent the most common choices that Native students opt for in seeking degrees in tertiary education. However, for the most part, Universities and Tribal Colleges are not working effectively enough to produce the levels of success that are significantly transforming of the wider social, economic and cultural crisis conditions within many Native American communities. This thesis will focus on how to develop a major transformation of the higher education sector generally, a focus which also positively includes the underdeveloped potential that lies within the Tribal Colleges and Native programs in various university sites. This thesis attempts to clarify what has gone wrong in the higher education of Native Americans and to propose a national, innovative strategy for intervention. Identifying what is problematic in existing approaches will build critical insights that will inform the new strategies for change. The overall argument is that new institutions which are more sensitive and responsive to Indigenous aspirations first and foremost need to be considered as a key in transforming Native American higher education performance. Rather than define absolutely all of the possible ingredients of what might be included in a new higher education model, this thesis works first to identify and aggregate a number of key barriers and constraints by collating different information streams. Once identified these critical elements, practices, values and structures that are deemed to be the major barriers to Native success are then used to inform the proposed new institutional framework. While a single institution model is ultimately proposed by this thesis, it should be regarded as ’an’ answer, not ’the’ answer. A broader intention of this thesis is to bring more focus to this area of concern and underdevelopment within Higher Education and suggest that there are different answers and possibilities (as the Maori examples have demonstrated) that are truly innovative, and which can profoundly impact Native American individual and community social, economic, cultural and political development and advancement.

description: Nos últimos anos, a produção de frangos de corte vem se consolidando como um dos setores mais dinâmicos do agronegócio brasileiro, particularmente em termos de produtividade e exportações. Esse trabalho tem como objetivo analisar a estrutura de oferta e de demanda derivada da produção de frangos de corte das principais regiões produtoras do país. Essa análise tem como base a estimação de uma função lucro translog normalizada e restrita (capital é um insumo fixo), e conseqüente cálculo das elasticidades-preço diretas, elasticidades-preço cruzadas e elasticidades de oferta. Além disso, a partir da função custo, são calculadas as elasticidades-preço cruzadas e as elasticidades de substituição de Allen e Morishima. Como resultado, conclui-se que os insumos variáveis (energia e mão-de-obra) podem ser considerados normais e complementares brutos no processo de produção.---------------------------------------------------In recent years, the production of cut chickens comes if consolidating as one of the sectors most dynamic of the Agribusiness Brazilian, particularly in terms of productivity and exportations. This article has as objective to analyze the structure of it offers and demand derived from the production of cut chickens of the main producing regions of the country. This analysis has as base the esteem of a function profit translog normalized and restricted (capital is the fixed input), and consequence direct calculation of the elasticity-price, elasticity-price crossed and elasticities of offers. Moreover, from the function cost, the elasticity-price crossed and the elasticities of substitution of Allen and Morishima are calculated. As result, one concludes that the changeable inputs (energy and labor) can be considered normal and complementary rude in the production process.
Intergenerationelles Wohnen – Chancen und Risiken für ältere und alte Menschen: Eine qualitative Forschung zum Einfluss intergenerationeller Wohnformen auf das Soziale Kapital älterer und alter Menschen in ländlichen Regionen

description: Die vorliegende Bachelorarbeit befasst sich mit dem aufkommenden Konzept des intergenerationellen Wohnens und fokussiert die persönlichen Sicht- und Erlebensweisen der älteren und alten Bewohnenden. Es werden die Fragen erörtert, inwiefern intergenerationelles Wohnen einen positiven Einfluss auf das Sozialkapital der älteren und alten Bewohnenden nehmen kann und welche Risiken diese Wohnform birgt. Weiter wird dargestellt, welche Rolle die Soziale Arbeit in diesem Setting ausführen kann. Aufgrund der wenigen empirischen Grundlagen für das intergenerationelle Wohnen auf dem Land konzentriert sich die vorliegende Arbeit auf die Untersuchung ländlicher Beispiele intergenerationeller Wohnprojekte. In einem qualitativen Zugang wurden sechs Leitfadeninterviews mit Bewohnenden im Alter von 66 bis 89 Jahren in drei unterschiedlichen intergenerationellen Wohnprojekten durchgeführt und anhand der zusammenfassenden Inhaltsanalyse ausgewertet. Die Forschungsergebnisse wurden auf der Grundlage der theoretischen Herleitung diskutiert und interpretiert. Die Erkenntnisse der Arbeit bestätigen, dass intergenerationelles Wohnen das Sozialkapital älterer und alter Menschen positiv beeinflussen kann und sich die Lebensqualität der Bewohnenden dank der nachbarschaftlichen Unterstützung und den vielseitigen Kontaktmöglichkeiten erhöht. Gleichzeitig zeigt sich, dass die Generationendurchmischung Herausforderungen für das nachbarschaftliche Zusammenleben birgt. Schlussfolgernd zeigt sich für die Soziale Arbeit ein grosses Potenzial im Handlungsfeld des intergenerationellen Wohnens an, welches in Form von Siedlungsassistenzen aufgegriffen werden kann.

description: The idea of the university as a mere transmitter of knowledge has long been obsolete. In the context of educational research and innovation, it is university teachers who fulfill these roles. This shift, along with the technological advancements of the 21st century, highlights the need for a thorough investigation into how well university teachers are equipped to face these new challenges. Consequently, various tools have been developed to provide a research framework that allows for comparisons between countries. Tools such as DigCompEdu have been used to assess teachers' digital competencies and to facilitate cross-country comparisons.
However, this study does not focus on teaching competencies but rather on exploring research competencies related to ICTs. In this context, a comparison is made between Spain and Ecuador to examine how two institutions from different countries operate, as well as how they function in relation to gender and the stage of academic career development. This aims to identify aspects that can serve as distinguishing factors.
The results show that there are no significant differences in the comparison of researchers from the two universities, finding significant changes only for specific aspects, establishing as differentiating factors the idea of a greater intention to use ICT for research by researchers at the University of Granada and showing how during the training of university teachers, confidence is acquired to train new researchers, establishing the ideal time for training once they have more than 10 years of research and with a permanent university link.
