Going through the lockdown: a longitudinal study on the psychological consequences of the coronavirus pandemic
2021
Coronavirus 2019 pandemic lockdown in Italy lasted for 2 months, 1 week and 2 days. During this long period, one of the longest in Europe, the restrictions produced effects on people’s psychological well-being, with consequences that also continued after lockdown. The purpose of the study is to investigate these effects and how they changed in the general population over a period of time. We are also interested in exploring people’s post-lockdown anxiety and concerns. We conducted an online survey using snowball sampling techniques. The longitudinal study consisted of four administrations covering a period of 10 weeks between April (baseline) and June (last follow-up). Levels of anxiety and…
Amygdaloid projections to the ventral striatum in mice: direct and indirect chemosensory inputs to the brain reward system
2011
Rodents constitute good models for studying the neural basis of socio-sexual behaviour. Recent findings in mice have revealed the molecular identity of the some pheromonal molecules triggering intersexual attraction. However, the neural pathways mediating this basic socio-sexual behaviour remain elusive. Since previous work indicates that the dopaminergic tegmento-striatal pathway is not involved in pheromone reward, the present report explores alternative pathways linking the vomeronasal system with the tegmento-striatal system (the limbic basal ganglia) by means of tract-tracing experiments studying direct and indirect projections from the chemosensory amygdala to the ventral striato-pall…
Association of child maltreatment subtypes and long-term physical health in a German representative sample
2018
ABSTRACT Background: Child maltreatment is a major public problem, associated with enormous consequences on the individual and socioeconomic level. Studies show a clear impact of child maltreatment on long-term physical health. However, there is a lack of analyses comprising a wide variety of subtypes of maltreatment and addressing cumulative effects of different maltreatment subtypes experienced during childhood on physical health. Objective: The objective of this analysis was to assess the association of different subtypes and the intensity of child maltreatment with long-term physical health outcomes. Methods: In a cross-sectional observational approach, a representative sample of the Ge…
The Relationship Between the Burnout Syndrome Dimensions and Body Mass Index as a Moderator Variable on Obese Managers in the Mexican Maquiladora Ind…
2021
Burnout syndrome (BS) and obesity are two growing conditions that affect employees’ health and company productivity. Recently, several studies have pointed to a possible relationship between both phenomena. However, such a relationship has not been clearly defined. This research analyzes the relationship between BS dimensions and body mass index (BMI), the latter being treated as a moderator variable among obese senior and middle managers in the Mexican maquiladora industry through a structural equation model. A total of 361 senior and middle managers (124 of them classified as obese under the World Health Organization’s criteria) completed both the Maslach Burnout Inventory-General Survey …
Convergence Analysis of Extended Kalman Filter for Sensorless Control of Induction Motor
2015
This paper deals with convergence analysis of the extended Kalman filters (EKFs) for sensorless motion control systems with induction motor (IM). An EKF is tuned according to a six-order discrete-time model of the IM, affected by system and measurement noises, obtained by applying a first-order Euler discretization to a six-order continuous-time model. Some properties of the discrete-time model have been explored. Among these properties, the observability property is relevant, which leads to conditions that can be directly linked with the working conditions of the machine. Starting from these properties, the convergence of the stochastic state estimation process, in mean square sense, has b…
Promotion of school engagement through dialogic teaching practices in the context of a teacher professional development programme
2021
This study was conducted in the context of a teacher professional development programme that aimed to improve dialogic teaching in the classroom, and it describes the programme and examines the change in teachers' dialogic teaching practices and pupils' classroom engagement during the programme. Data on pupils' school engagement were collected using classroom video recordings and students' self-ratings at the end of the lesson including dialogic teaching practices. The participants comprised seven in-service teachers and their 140 pupils (10- to 15-year-olds) from two comprehensive schools. The findings indicated positive change in the use of dialogic teaching practices and in observed pupi…

Undergraduate Students’ Acceptance of a Reciprocating One-File System for Endodontic Treatment
2020
Abstract Objectives Reciprocating endodontic one-file systems are a comparatively new method for root canal shaping. Even though the mechanical properties are comparable to modern rotating mechanical systems, data about subjective assessment and application quality are scarce. This study evaluates the reciprocating one-file system in undergraduate education. Materials and Methods A total of 42 undergraduate students without experience regarding reciprocating file systems filled in a questionnaire in four different points in time (t 1–t 4) anonymously. The questionnaire was based on a numerical rating scale ranging from 0 to 10. Statistical Analysis A least significant difference post-hoc an…
Exploring Online Customer Experience Formation: How do Customers Explain Negative Emotions during Online Shopping Encounters?
2019
We investigated online customer experience formation by using customers’ own explanations of their negative emotions during their online shopping encounters. Survey data from 1,786 Finnish online shoppers were used to identify customers who experienced strong negative emotions during online shopping encounters (N = 215) and the causes of their negative emotions were then analyzed in depth from their written descriptions. Our findings indicated that customers attributed most of their negative emotions to online store characteristics, including user interface, product and service range, pricing, and trustworthiness; however, some negative emotions were also attributable to factors outside of …
