Morphological, electrical and optical properties of organic light-emitting diodes with a LiF/Al cathode and an Al-hydroxyquinoline/diamine junction
2004
Abstract We report the results of the morphological, electrical and optical characterisation of double-layer Alq3-based organic emitting diodes with a lithium fluoride (LiF)/Al cathode. A detailed electron microscopy investigation of their cross-section shows the presence of LiF isolated grains underneath the Al film. Due to the introduction of the LiF layer, luminance was larger than 30,000 cd/m2 at a bias voltage VB=25 V with a maximum external luminous efficiency as large as 46 lm/W at VB=20 V. Performing on/off VB cycles at a very low frequency, each time a recovery of the initial electric and luminous performance was observed. The non-exponential decay of both electric current and lumi…
The Impact of Harmonization on ELISPOT Assay Performance
2011
During more than 25 years of application in immunological sciences, ELISPOT has been established as a routine, robust, versatile, and reliable assay. From basic research to clinical immune monitoring, ELISPOT is being used to address the quantification and (to a lesser extent) functional characterization of immune cells secreting different molecules in the context of health and disease, immune intervention, and therapy in humans and other species [Kalyuzhny (Ed.) (2005) Handbook of Elispot: methods and protocols, Vol. 302, Humana Press Inc., Totowa, NJ]. Over the last decade, ELISPOT assays have been increasingly implemented as an immune-monitoring tool in clinical trials [Schmittel et al. …
Testing Motivacional theories in Music Education: the role of Effort and Gratitude
2019
Acquiring musical skills requires sustained effort over long periods of time. This work aims to explore the variables involved in sustaining motivation in music students, including perceptions about one’s own skills, satisfaction with achievements, effort, the importance of music in one’s life, and perception of the sacrifice made. Two models were developed in which the variable of gratitude was included to integrate positive psychology into the motivational area of music education. The first predicts effort, while the second predicts gratitude. The models were tested using a sample of 84 music students. Both models were fitted using Bayesian analysis techniques to examine the relationship …
The Relative Efficacy of Price Announcements and Express Communication for Collusion: Experimental Findings
2014
Collusion is when firms coordinate on suppressing competition, and coordination typically requires that firms communicate in some manner. This study conducts experiments to determine what modes of communication are able to produce and sustain collusion and how the efficacy of communication depends on firm heterogeneity and the number of firms. We consider two different communication treatments: non-binding price announcements and unrestricted written communication. Our main findings are that price announcements allow subjects to coordinate on a high price but only under duopoly and when firms are symmetric. While price announcements do result in higher prices when subjects are asymmetric, t…
Physical integration: A causal account for consciousness
2014
The issue of integration in neural networks is intimately connected with that of consciousness. In this paper, integration as an effective level of physical organization is contrasted with a methodological integrative approach. Understanding how consciousness arises out of neural processes requires a model of integration in just causal physical terms. Based on a set of feasible criteria (physical grounding, causal efficacy, no circularity and scaling), a causal account of physical integration for consciousness centered on joint causation is outlined.
Exploring self-efficacy beliefs in symbiotic collaboration with students: an action research project
2019
This paper presents a participatory action research project in which teacher-researchers, student-researchers and student-subjects collaborated on a research project in a working-group format to in...
How common are inclusive educational practices among Finnish teachers?
2017
Several instructional strategies have been recommended for use in heterogeneous classrooms, but the frequency of their actual use has remained largely unknown. Therefore, an electronic survey was sent to Finnish comprehensive school teachers (N = 2276) in order to assess the prevalence of three selected inclusive strategies: co-teaching, group work, and differentiation. The results showed that co-teaching was used by 42% and group work by 43% of the teachers at least on a weekly basis, while differentiation was used regularly by 83% of teachers. The application of all strategies was strongly associated with teacher category, with subject teachers using them less frequently than classroom te…
Predicting University Adjustment from Coping-Styles, Self-Esteem, Self-Efficacy, and Personality: Findings from a Survey in a Sample of Italian Stude…
2021
Starting university life requires that students learn to cope with several personal, academic, and social challenges. A wide array of variables affects how students adjust to university life. This study was aimed to investigate which factors among coping styles, self-esteem, self-efficacy, and personality traits (i.e., diligence, relational availability, mental flexibility, activity, and emotional stability) best predicted the levels of university adjustment in a sample of university freshmen (N = 204, 63% women). Data were collected using self-report instruments. Multiple regressions analyses were conducted to identify the most significant predictors of adjustment to college. Our findings …
Factors influencing tourists’ intention to use COVID-19 contact tracing app
2020
AbstractThe purpose of this study was to develop and test a model that explores the antecedents of tourists’ acceptance of COVID-19 contact tracing app (CTA). Data was obtained from a crowdsourcing platform (Pollfish), in which 400 respondents answered the questionnaire. We used SmartPLS to analyse the data. Results reveal that trust and structural assurance have the strongest relationship. Furthermore, the relationship between trust and destination safety was positive. Finally, self-efficacy moderated the relationship between trust and intention, implying that trust was stronger for tourists who have higher levels of self-efficacy. Recommendations are offered.
Self-isolation for the self-centered: Negative framing increases narcissists' willingness to self-isolate during COVID-19 through higher response eff…
2021
Abstract The coronavirus (COVID-19) pandemic has come with various health recommendations restricting personal freedom, such as social distancing and self-isolation. Considering the personal sacrifices involved, not all individuals are equally willing to comply with such recommendations, which might pose a health hazard further down the line. In a high-powered study (N = 800), we show that individual differences in narcissism influence the willingness to self-isolate during pandemics, with individuals high (vs. low) in narcissism being less willing to self-isolate. However, this tendency can be offset by tailored message framing. Specifically, individuals high (vs. low) in narcissism are mo…
