“Can do!” Teacher Promotion of Optimism in Response to Student Failure Expectation Expressions in Classroom Discourse
2019
This study offers detailed observational analyses of how teachers use optimism as an instructional resource when responding to students’ failure expectation displays in classroom situations. The results were based on video-recordings of 25 lessons in two Finnish part-time special education settings, analysed by means of applied conversation analysis. The results showed that the teachers boosted optimism by inverting students’ negative utterances, giving examples of successful experiences of peers, offering praise for students’ earlier performance or focusing on problems through instructional support. The study underlines the importance of addressing and elaborating students’ negative learni…

Pirmie pavadoņu novērojumi Latvijas Universitātē pirms 60 gadiem
2018
Latvijas Universitātes Muzeja virtuālā izstāde „Pirmie pavadoņu novērojumi Latvijas Universitātē pirms 60 gadiem” stāsta par 1957. – 1958. gadu, kad tika palaisti pirmie Zemes mākslīgie pavadoņi. Universitātes astronomi aktīvi iesaistījās to novērošanā, jo bija nepieciešams noteikt pavadoņu orbītas. Sākumā notika pavadoņu vizuālie novērojumi, kuros bija iesaistīti daudzi studenti. Tā kā tie nebija pietiekami precīzi, astronomi sāka domāt par pavadoņu fotografēšanu. Pirmos uzņēmumus ieguva 1958. gadā uz LU galvenās ēkas jumta Raiņa bulvārī 19. Kamera, ar kuru tas veikts, glabājas Latvijas Universitātes Muzejā. Turpmākajos gados Latvijas Universitātes astronomi izvirzījās pavadoņu novērošanas…
Sexual behaviors and function during menopausal transition—does menopausal hormonal therapy play a role?
2020
Objectives: The menopausal transition is a biological adaptation to the variety of life changes (body, comorbidities, relationship), but that biology is not an “end all” in the context of sexual function and overall sexual health. The aim of this study is to evaluate determinants altering the risk of female sexual dysfunction (FSD) and other sexual problems and to establish whether menopausal hormonal therapy (MHT) decreases that risk and modifies sexual behaviors. Methods: A cross-sectional observational study was conducted in 210 women between the ages of 45 and 55. Two groups were identified: MHT users (n = 107) and controls—MHT non-users (n = 103). Diagnostic and Statistical Manual of M…

Emulating Human Supervision in an Intelligent Tutoring System for Arithmetical Problem Solving
2014
This paper presents an intelligent tutoring system (ITS) for the learning of arithmetical problem solving. This is based on an analysis of a) the cognitive processes that take place during problem solving; and b) the usual tasks performed by a human when supervising a student in a one-to-one tutoring situation. The ITS is able to identify the solving strategy that the student is following and offer adaptive feedback that takes into account both the problem's constraints and the decisions previously made by the user. An observational study shows the ITS's accuracy at emulating expert human supervision, and a randomized experiment reveals that the ITS significantly improves students' learning…
Factores asociados al estrés prenatal y la ansiedad en gestantes durante el COVID-19 en España
2022
AIM OF THE STUDY To describe prenatal stress and state anxiety levels in pregnant women living in Spain during the lockdown of the first wave of COVID-19 and its relation with obstetric factors, perception of health care, and concerns about the socio-sanitary situation. METHODS The present study is an observational, correlational, and cross-sectional quantitative study. The participants in the study were pregnant women recruited through non-probabilistic convenience and snowball sampling during the lockdown. A web link was provided to an online questionnaire designed for this research, which collected socio-demographic and obstetric variables, perceptions of health care received during the …
Il reporting per segmenti nei settori del trasporto pubblico locale e della cura della salute. Esperienze a confronto.
2020
This paper examines issues of cost and revenue allocation that arise when segment reporting is carried out in local public transportation and healthcare companies. It also presents reports by segment schemes that can be used by companies operating in the aforementioned sectors. The research was carried out with the qualitative methods of participant observation and document analysis. this study focuses on the-oretical principles that have been derived from experiences carried out in the design and implementation of a segment reporting system in two companies operating in the public transportation and healthcare sectors. The analysis of the issues and solu-tions adopted by the companies obse…
Accountable to Whom? : The Use of Media to Communicate Educational Accountability to Latino Families in a California Middle School
2018
This paper explores how one Title I middle school in California responds to high-stakes accountability during an era of educational reform, and how one first-generation Latino immigrant family comes to understand the school’s focus on test scores, high expectations, and academic achievement. Drawing from a larger Language Socialization study that utilizes participation observation and interview data, the paper provides ethnographic snapshots to demonstrate the ways in which one school communicated under, with, and through high stakes educational reform policies via a variety of media while functioning under Program Improvement status, and how the focal family participated in and negotiated …
Aortic Stiffness in HIV Infection with and without Antiretroviral Therapy. A Meta-analysis of Observational Studies
2020
Background: The risk of Cardiovascular (CV) events is higher in HIV-infected patients (HIV+) compared to HIV-uninfected persons (HIV−). Large artery stiffness, a well-documented predictor of adverse CV prognosis, may mediate this enhanced risk. It is usually assessed by measuring aortic Pulse Wave Velocity (aPWV). Studies examining arterial stiffness in HIV+ yielded inconsistent results. We performed a meta-analysis with the aim to evaluate the association of HIV infection and its therapy [Antiretroviral Therapy (ART)] with aPWV. Design and Method: The Standardized Mean Difference (SMD) and corresponding 95% confidence intervals were calculated for aPWV in different comparison groups. Stati…
