Bianchi groups are conjugacy separable

We prove that non-uniform arithmetic lattices of $SL_2(\mathbb{C})$ and in particular the Bianchi groups are conjugacy separable. The proof based on recent deep results of Agol, Long, Reid and Minasyan.Comment: to appear in J. Pure and Applied Algebr

Outras aplicações de óleos essenciais - pesquisas para uso em parasitologia veterinária.

o controle de parasitas de impacto em animais de produção é realizado por meio de antiparasitários comerciais, tais como carrapaticidas e vermífugos. Existem diferentes classes de drogas veterinárias que podem ser utilizadas, mas a maioria delas não possui a eficácia esperada em função da forte resistência que os parasitas desenvolveram. Dessa forma, os produtores se vêm obrigados a aumentar as doses recomendadas ou tratar os animais de forma mais intensa, o que pode acarretar em riscos de contaminação do ambiente e dos subprodutos dos animais, tais como carne e leite. Diante desse quadro, a pesquisa de novos princípios ativos de origem vegetal para o controle de parasitas tem sido realizada de forma intensa nos últimos anos. Os óleos essenciais têm demonstrado elevada atividade biológica em diferentes ensaios laboratoriais e possuem uma mistura de sustâncias que podem agir de forma sinérgica. Essa linha de pesquisa em parasitologia veterinária é bastante recente no Brasil e existem muitas informações que precisam ser esclarecidas

Kahoot! and socrative in higher education: a comparative study

Technology brings new challenges and opportunities to higher education institutions, as it can promote learner-centered activities. Mobile devices such as smartphones are very popular among students and can easily engage them and promote motivation and active learning. In this study, we investigate Tourism undergraduate students’ perceptions on the use of mobile technology in the classroom, specifically two quiz makers in a comparative perspective: Kahoot! and Socrative. The purpose of this two-stage study is to identify and meet students’ preferences, so as to design activities that can truly promote learning. The participants are Mathematics and English students from a Portuguese higher education institution. At the first stage, in a preliminary survey, 33 students have identified their quiz preferences and most of them (87,88%) selected Socrative as their favourite quiz maker. At the second stage, students were also inquired about their general perceptions and preferred features, such as collaborative mode, competition mode, self-paced mode or immediate feedback. Similar studies have shown that these tools can promote engagement, motivation, concentration and learning. Therefore, we hope to contribute to a better understanding of how technology can improve the learning process.info:eu-repo/semantics/publishedVersio

Student receptiveness to Kahoot! in higher education

The use of technology in higher education has been increasing in the past few years and new online tools have emerged for very different purposes. Kahoot! is an example of a platform that can be used for reviewing content and motivating students for learning. Our research is based on data from a quantitative survey conducted in the previous school year and the participants were 86 undergraduate students from a Portuguese higher education institution. The preliminary results of the survey showed that students are very receptive to this tool and highly recommend it, as it promotes motivation. Other studies have shown that higher education students are usually receptive to web tools and consider technology can positively impact learning. To better understand students’ responses to the platform, in this study we aim at analysing the results according to area of study and investigating new correlations between variables, specifically (i) gender vs receptiveness to Kahoot!, (ii) gender vs recommendation of its use and (iii) technology readiness vs receptiveness to Kahoot!.info:eu-repo/semantics/publishedVersio

Assessing students' engagement levels during lockdown: a survey in tourism degrees

In early 2020, the crisis of a new virus and a pandemic context took the world by storm. All sectors of society were affected: health, economics,… and education was no exception, with all levels suspending face-to-face classes, which were replaced by online activities. In view of this situation, several doubts and uncertainties emerged among educators, but one question stood out: how to proceed with teaching activities in the online format without compromising the commitment and engagement of the students? Within this context, the teachers involved in this study sought to adapt the activities and teaching materials to the exclusive use of technology and promoted asynchronous tasks, which could be developed independently by the students. In order to understand how the profound changes in Higher Education were experienced by students, a quantitative survey was conducted. The participants in the study are undergraduate students from a Portuguese Higher Education institution attending the curricular units of Statistical Analysis and English.info:eu-repo/semantics/publishedVersio

Enhancing students’ motivation with Kahoot!: a case study in English and mathematics

In the last few decades, technology has advanced in multiple fields, including Education. Some of its benefits include improving student performance and motivation, fostering active learning and tracking student progress. As a "new learning generation" is around, profound changes to the role and function of both teachers and students are particularly vital, so active, cooperative and participative methodologies of learning must be privileged. Given that most higher education students are technology savvy and very receptive to the integration of Web 2.0 tools in class, the teachers involved in this study began using Kahoot! in their classes as an alternative teaching methodology. The participants in the study are undergraduate students from a Portuguese higher education institution and encompassed the curricular units of Statistical Analysis and English. The aim of the study is to investigate students’ perceptions of how Kahoot! can be used as a tool for testing new vocabulary, reviewing class content or designing warm-up activities. A quantitative survey is being conducted to gather information about students’ insights on the use of Kahoot!. Similar studies have shown that students are generally receptive to the use of this tool and find it useful to increase their motivation.info:eu-repo/semantics/publishedVersio
