A New Academic Quality at Work Tool (AQ@workT) to Assess the Quality of Life at Work in the Italian Academic Context

2022

Refereed/Peer-reviewed The present study provides evidence for a valid and reliable tool, the Academic Quality at Work Tool (AQ@workT), to investigate the quality of life at work in academics within the Italian university sector. The AQ@workT was developed by the QoL@Work research team, namely a group of expert academics in the field of work and organizational psychology affiliated with the Italian Association of Psychologists. The tool is grounded in the job demands-resources model and its psychometric properties were assessed in three studies comprising a wide sample of lecturers, researchers, and professors: a pilot study (N = 120), a calibration study (N = 1084), and a validation study …

Hydrogen plasma induced photoelectron emission from metal surfaces

2018

Low temperature hydrogen plasmas are strong sources of vacuum ultraviolet radiation. The properties of laboratory plasmas can be influenced by surface processes induced by photons with their energies exceeding the surface work function of the wall material. In this work, the plasma induced photoelectron emission has been studied with different ion sources. The emission depends on the mechanical design of the plasma device, plasma heating method and the discharge power (density). Parametric studies include the quantifying of the emission from different metal surfaces, commonly used as plasma facing materials in ion sources, as well as alkali metal covered surfaces. Experimental studies sugges…

Management Models in Organizations and Problems of CSR Promotion: Lithuanian Case

2006

The article tackles the problems of CSR initiatives and human resource development in Lithuanian organizations. Proceeding from the results of empirical researches the authors analyze social-cultural obstacles, which blocks up the headway of CSR processes, and particularly emphasize the problems of social responsibility in organizations of state/public administration, and especially in educational system. They maintain and prove necessity of value management and reconstruction of management models through introducing of ethics infrastructure in organizations.

The roles of achievement-related behaviours and parental beliefs in children´s mathematical performance

2003

This study aimed to investigate the developmental dynamics between children's mathematical performance, the task-focused versus task-avoidant behaviours they show in the classroom, and their parents' beliefs concerning their school competence. The mathematical performance of 111 six- to seven-year-old children was tested, and their task-focused versus task-avoidant behaviours were rated by their teachers four times during their first school year. Parents filled in questionnaires measuring their skill-specific and general beliefs about their children's school competencies at the beginning and at the end of the school year. The results showed that parents' beliefs in their children's general …

The price of safety: food deprivation in early life influences the efficacy of chemical defence in an aposematic moth

2018

Aposematism is the combination of a primary signal with a secondary defence that predators must learn to associate with one another. However, variation in the level of defence, both within and between species, is very common. As secondary defences influence individual fitness, this variation in quality and quantity requires an evolutionary explanation, particularly as it may or may not correlate with variation in primary signals. The costs of defence production are expected to play a considerable role in generating this variation, yet studies of the cost of chemical defence have focused on species that sequester their defences, while studies in species that produce them de novo are scarce. …

Effectiveness of a kindergarten-based intervention to increase vegetable intake and reduce food neophobia amongst 1-year-old children: a cluster rand…

2021

Background: Children’s first years of life are crucial to their future health. Studies show that a varied diet with a high intake of vegetables is positive in several domains of health. The present low vegetable intake amongst children is, therefore, a concern. Food neophobia is a common barrier to vegetable intake in children. As most Norwegian children attend kindergarten from an early age, kindergartens could contribute to the prevention of food neophobia and the promotion of vegetable intake. Objective: The aim of this study was to assess the effect of a cluster randomised trial amongst 1-year-old children in kindergarten to reduce food neophobia and promote healthy eating. Methods: Kin…

Student participation in peer interaction : use of material resources as a key consideration in an open-ended problem-solving mathematics task

2021

This study explores how students deal with material resources in their peer interaction when working in pairs in an open-ended problem-solving task. The productive use of material resources can be expected to support successful peer work. However, research into social phenomena in peer interaction is needed in order to identify and describe productive and less productive forms of dealing with material resources as students participate in open-ended problem-solving tasks. Consequently, this explorative study responds to this research need. Based on multimodal data, including video recordings, transcribed talk and the written contributions from four pairs of Year 7 students aged 12-13 years, …

Understanding Estonian phraseological units on the basis of Finnish : contributing and misleading factors

2020

Vironkielistä tekstiä lukevien suomalaisten on havaittu hyödyntävän monenlaisia strategioita selvittääkseen sukukielen sanojen merkityksiä. Yksi niistä on pohjustaminen (priming). Kun kyseessä on fraseologinen yksikkö, yksi osa (prime) pohjustaa toisen osan eli kohdesanan (targetin) esiintymistä, mikäli prime on tunnistettavissa äidinkielen perusteella. Tässä artikkelissa kuvaamme muutamia erityistilanteita. Miten pohjustimen ja kohdesanan välinen etäisyys tai teemanvaihdos vaikuttavat ’petollisen ystävän’ ymmärtämiseen? Lisäksi tutkimme sitä, miten ahdasrajainen semanttinen kategoria ohjaa siitä puuttuvan jäsenen merkityksen löytämistä ja millaisia perusteita käännösratkaisuille on löydett…

AN EXPERIMENTAL WORKFLOW FOR THE VIRTUAL RECONSTRUCTION OF ANCIENT STATUES

2021

The work aims to investigate the main steps of a virtual reconstruction process of ancient statues, inspecting theoretical and technical approaches. Two fragmentary Roman statues from the "Sanctuary of Isis", inside the Archaeological Park of Lilibeo-Marsala (Italy), were chosen as a case study. Trying to preserve the original artwork authenticity and the transparency of the reconstruction method, a workflow was developed following three steps: 1) 3D survey and reality based model production; 2) evaluation of reconstruction hypotheses based on a rigorous selection of reference sources; 3) 3D modelling and source-based model creation. Three models for multiple visualization purposes were car…
