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
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
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
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
An Analysis of the Decay with Predictions from Heavy Quark and Chiral Symmetry
This paper considers the implications of the heavy quark and chiral
symmetries for the semi-leptonic decay . The general kinematic analysis for decays of the form {\sl
pseudoscalar meson vector meson pseudoscalar meson lepton
anti-lepton} is presented. This formalism is applied to the above exclusive
decay which allows the differential decay rate to be expressed in a form that
is ideally suited for the experimental determination of the different form
factors for the process through angular distribution measurements. Heavy quark
and chiral symmetry predictions for the form factors are presented, and the
differential decay rate is calculated in the kinematic region where chiral
perturbation theory is valid.Comment: 15 pages, uses jytex.tex and tables.tex; 3 figures not included but

Inducing charges and currents from extra dimensions
In a particular variant of Kaluza-Klein theory, the so-called induced-matter
theory (IMT), it is shown that any configuration of matter may be geometrically
induced from a five-dimensional vacuum space. By using a similar approach we
show that any distribution of charges and currents may also be induced from a
five-dimensional vacuum space. Whereas in the case of IMT the geometry is
Riemannian and the fundamental equations are the five-dimensional Einstein
equations in vacuum, here we consider a Minkowskian geometry and the
five-dimensional Maxwell equations in vacuum.Comment: 8 pages. Accepted for publication in Modern Physics Letters

Acute kidney injury in pregnancy: a clinical challenge
The incidence of acute kidney injury in pregnancy declined significantly over the second half of the 20th century; however, it is still associated with major maternal and perinatal morbidity and mortality. A set of systemic and renal physiological adaptive mechanisms occur during a normal gestation that will constrain several changes in laboratory parameters of renal function, electrolytes, fluid and acid-base balances. The diagnosis of acute kidney injury in pregnancy is based on the serum creatinine increase. The usual formulas for estimating glomerular filtration rate are not validated in this population. During the first trimester of gestation, acute kidney injury develops most often due to hyperemesis gravidarum or septic abortion. In the third trimester, the differential diagnosis is more challenging for the obstetrician and the nephrologist and comprises some pathologies that are reviewed in this article: preeclampsia/HELLP syndrome, acute fatty liver of pregnancy and thrombotic microangiopathies
Stress appraisal, coping, and work engagement among police recruits: an exploratory study.
This study investigated the influence of stress appraisal and coping on work engagement levels (Absorption, Vigour, and Dedication) of police recruits. Participants were 387 men, ages 20 to 33 yr. (M = 24.1, SD = 2.4), in their last month of academy training before becoming police officers. Partially in support of predictions, work engagement was associated with Stressor control perceived, but not Stress intensity experienced over a self-selected stressor. Although the three dimensions of work engagement were explained by Stressor control and coping, Absorption was the dimension better explained by these variables. Police recruits reporting higher Absorption, Vigour, and Dedication reported using more Active coping and less Behavioural disengagement. Results showed that stress appraisal and coping are important variables influencing work engagement among police recruits. Findings suggested that future applied interventions fostering work engagement among police recruits should reinforce perceptions of control over a stressor as well as Active coping strategies
Superstatistics, thermodynamics, and fluctuations
A thermodynamic-like formalism is developed for superstatistical systems
based on conditional entropies. This theory takes into account large-scale
variations of intensive variables of systems in nonequilibrium stationary
states. Ordinary thermodynamics is recovered as a special case of the present
theory, and corrections to it can be systematically evaluated. A generalization
of Einstein's relation for fluctuations is presented using a maximum entropy
condition.Comment: 16 pages, no figures. The title changed, some explanations and
references added. Accepted for publication in Phys. Rev.
