Evaluating Assessment. Validation with PLS-SEM of ATAE Scale for the Analysis of Assessment Tasks
2020
One of the essential functions of university teachers lies in the decision-making process regarding the various components included in assessment process design, where the quality of assessment tasks is a key aspect. This study presents both validation of an instrument for students to evaluate the assessment tasks and the model that upholds the relationships between constructs that characterise the assessment tasks. Working from a review of the literature, a theoretical model has been devised featuring the characteristics of the assessment tasks and the relationships between them. The Analysis of the Assessment and Learning Tasks questionnaire (ATAE) has been designed to check them, based o…
Motivational configurations of cultural intelligence, social integration, and performance in global virtual teams
2021
Abstract Global virtual teams (GVTs), electronically connected workgroups of geographically dispersed team members in multinational settings, may suffer from less social integration. However, they may also benefit from an increased ability to process information due to a richer portfolio of ideas and problem-solving approaches that the team’s diversity provides. We propose that the cultural intelligence (CQ) of team members contributes positively to social integration in GVTs and improves performance. Using data from 263 GVTs, we utilized both structural equation modeling and necessary condition analyses to explore the associations between motivational CQ and a team’s social integration and…
Financial Sustainability and Morphogenesis of Urban Transformation Project
2015
The urban transformation projects are very complex and have to be examined from several points of view (socio-cultural, environmental, infrastructural, administrative, and economic-financial) to determine their sustainability. This study aims to test the financial analysis as a tool for outlining the morphogenesis of the project’s characteristics and exploring the frontiers of the financial feasibility especially when the urban projects, according to Italian laws, involve Public Private Partnerships (PPPs). A financial model is applied to a case study (the transformation of an abandoned railway area) in which the absence of an adequate returns on investment, because of the crisis of the rea…
Measurement invariance of the Prosocial Behavior Scale in three hispanic countries (Argentina, Spain, and Peru)

Centro de Investigación Interdisciplinar en Valores, Integración y Desarrollo Social; Argentina Abstract: In a growing context of multiculturalism, prosocial behavior is important to build effective social exchange and service orientation among university students. The present study investigates prosocial behavior from a psychometric approach, to obtain evidence of the in…
Technical and economical comparison between different topologies of PV plant under mismatch effect
2014
This paper presents a technical and economical comparative analysis between two topology of photovoltaic plant. In particular the performances of series-parallel (SP) and total cross tied (TCT), topologies are taken into account, referring to a partially shaded photovoltaic plant. Thanks to a simulation model developed, in the paper the mismatch effects due to three different shading conditions, for SP and TCT topology plant, are quantified. Since the TCT solution, even though increase the energy production, raise the complexity of plants as well as their costs, an evaluation of the individual costs of each component of a SP and TCT plant topology, as PV modules, support structure, inverter…
Radiation model of a TiO2-coated, quartz wool, packed-bed photocatalytic reactor
2010
The radiation field of a packed-bed photocatalytic reactor filled with quartz wool coated with titanium dioxide was modeled using the Monte Carlo technique and the following information: the radiation flux emitted by the lamps, the diameter size distribution of the quartz fiber cloth, the mass of quartz fibers and of TiO2 that was immobilized on the fiber surface as well as the refractive index and the spectral absorption coefficient of the materials of the system. Modeling predictions were validated with radiometer measurements of the transmitted radiation through the reactor, the root mean square error being < 9.7%. Finally, by means of a parametric study, the validated model was used to …
Wikipedia network analysis of cancer interactions and world influence
2019
AbstractWe apply the Google matrix algorithms for analysis of interactions and influence of 37 cancer types, 203 cancer drugs and 195 world countries using the network of 5 416 537 English Wikipedia articles with all their directed hyperlinks. The PageRank algorithm provides the importance order of cancers which has 60% and 70% overlaps with the top 10 cancers extracted from World Health Organization GLOBOCAN 2018 and Global Burden of Diseases Study 2017, respectively. The recently developed reduced Google matrix algorithm gives networks of interactions between cancers, drugs and countries taking into account all direct and indirect links between these selected 435 entities. These reduced n…
Barbara Sokołowska Brukalski. Graphic Analysis of the House on Niegolewskiego Street
2017
The project analyzed in this paper by the critical and digital redrawing is the House on Niegolewskiego Street of 1927–28, designed by Barbara Sokołowska for her and her husband, Stanislaw Brukalski, inspired by the Neoplasticism ideas, the paintings of Mondrian and De Stijl. In its details the house seems to recall that one in Utrecht by G.T. Rietveld of 1924, with a very large living room, a studio overlooking a double height and a spiral stair connecting the two floors into one space defined by translated planes and pure volumes.
Mindful Attention Awareness in Spanish Palliative Care Professionals
2017
Abstract. Mindfulness is conceived as a state in which the individual pays full attention to everything that is happening around him or her. The Mindful Attention Awareness Scale (MAAS) is the most popular instrument for assessing mindfulness. Studies on its structure have shown some conflicting results. This study aims to offer new evidence on the dimensionality and reliability of the MAAS, handling both SEM and IRT procedures, in palliative professionals. The sample was composed of 385 professionals from a national online survey. First, two Confirmatory Factor Analyses (CFAs) were specified, estimated, and tested, with one- and two-factor structures, respectively. Second, the Graded Resp…
Thermophilic anaerobic digestion of pulp and paper mill primary sludge and co-digestion of primary and secondary sludge
2012
Anaerobic digestion of pulp and paper mill primary sludge and co-digestion of primary and secondary sludge were studied for the first time in semi-continuously fed continuously stirred tank reactors (CSTR) in thermophilic conditions. Additionally, in batch experiments, methane potentials of 210 and 230 m³CH₄/t volatile solids (VS)(added) were obtained for primary, and 50 and 100 m³CH₄/tVS(added) for secondary sludge at 35 °C and 55 °C, respectively. Anaerobic digestion of primary sludge was shown to be feasible with organic loading rates (OLR) of 1-1.4 kgVS/m³d and hydraulic retention times (HRT) of 16-32 d resulting in methane yields of 190-240 m³CH₄/tVS(fed). Also the highest tested OLR o…
