Study of phase transition in Bi3TiNbO9-BaBi2Nb2O9 ceramics

2016

Abstract The subject of the paper is lead free bismuth layer structure oxides (1-x)Bi3TiNbO9-xBaBi2Nb2O9 (x=0; 1; 2; 3 mol). The influence of Bi3TiNbO9/BaBi2Nb2O9 ratio on dielectric and structural properties was studied in a wide range of temperatures. Change in the ratio causes a decrease in the maximum value of dielectric permittivity and shifts the temperature of ε’max to low values, leading to linear decreasing of average grain size and linear increasing of ceramics density. These results indicate an augment of the packing degree and the participation of pores are significantly decreased with the increase of BaBi2Nb2O9 compound intake. Moreover, for 0.7Bi3TiNbO9-0.3BaBi2Nb2O9 ceramics …

Propiedades psicométricas del cuestionario ActEval sobre la actividad evaluadora del profesorado universitario

2013

This article presents the results of the empirical validation of the questionnaire ActEval (Self-Report on the Evaluation Activity of university teachers). ActEval attempts to identify how important teachers consider a variety of assessment tasks, whether they feel competent, and to what extent they use them in their daily practice, in line with the new competences under the European Higher Education Area. Validation is studied using Non-Metric Multidimensional Scaling (PROXSCAL) and the reliability results show high levels of internal consistency. The data suggest that some items in the questionnaire should be reviewed in order to obtain an effective tool for the analysis of evaluation pra…

Towards a sustainable leader-follower relationship: constructive dissensus, organizational virtuousness and happiness at work (haw)

2020

This paper examines how leaders and followers can interact positively under complex and bounded conditions. For this purpose, this paper conceptualizes and measures the concept of constructive dissensus. Constructive dissensus relates to a mutual understanding leading to a situation of coregulation. In addition, the relationship between constructive dissensus and happiness at work is examined on the basis of affective events theory. Furthermore, the mediating role of organizational virtuousness is assessed. Through structural equation modeling, a multilevel analysis was performed. Data from 130 bank branches and 606 employees were gathered. The results reveal a direct effect of constructive…

Identity and relationship frames in medical leadership communication

2021

PurposeA frame is an interpretive scheme of meanings that guide participants’ interpretations of social interaction and their actions in social situations (Goffman, 1974). By identifying early-career physicians’ identity and relationship frames, this study aims to produce information about socially constructed ways to interpret leadership communication in a medical context.Design/methodology/approachThe data consist of essays written by young physicians (n= 225) during their specialization training and workplace learning period. The analysis was conducted applying constructive grounded theory.FindingsThree identity and relationship frames were identified: the expertise frame, the collegial …

Co-costruzione dell'apprendimento: dalla pratica riflessiva all'azione. Inquiry-Based Laboratory e action learning nella formazione dei futuri docent…

2022

Il presente lavoro espone gli esiti di una ricerca sperimentale a gruppo unico, condotta con 1350 corsisti e 120 docenti di laboratorio frequentanti il V ciclo del corso di specializzazione per le attività di sostegno didattico per le scuole dell’infanzia, primaria, secondaria di primo e secondo grado dell’Ateneo di Palermo svoltosi nell’A.A. 2020/2021. La cornice teorica all’interno della quale si delinea la ricerca è quella dell’approccio Inquiry-Based Laboratory (IBL), del Reflective Learning e dell’Action Learning, fondamentale per la costruzione di una professionalità docente competente, consapevole e responsabile. Il percorso di ricerca ha applicato il modello dell’IBL alle attività l…

Novel fasciocutaneous flaps for the reconstruction of complicated lower extremity wounds

2009

Summary: Reconstruction of the leg is particularly challenging especially when the defect involves its lower third. The options for lower leg reconstruction are very few because of the lack of local soft tissue available for transfer. Novel fasciocutaneous flaps nourished by perforator vessels have been developed and are increasingly used as a valuable local alternative to the local flaps, with their high complication rates, and to the microsurgical flaps, with their more difficult and specialized technique. They provide local tissue, replacing like with like, but they harvest it from a distant, undamaged, region of the leg, which means healthy and well-vascularized tissue. They do not need…

Legitimacy and relevance of a performance measurement system in a Finnish public-sector case

2019

Purpose This study investigates the difficulties involved in translating stakeholder expectations into action and maintaining legitimacy through the use of a performance measurement system (PMS) created in a Finnish regional development company (RDC). This longitudinal case study illustrates the fluctuating and socially constructed nature of legitimacy in the public sector. Design/methodology/approach This qualitative case study longitudinally analyzes the various developments occurring during and after the development of a PMS system for the case organization. Empirical data include interviews, workshops, observation and other materials relating to the case organization. Findings The init…

Leisure Boating Environmental Footprint: A Study of Leisure Marinas in Palermo, Italy

2022

Ports have played a significant role in the touristic development and further economic growth of Italy. It is the country with the highest number of berths among the nations in the Mediterranean Sea; over time, Italy has created ports with a range of functions. Therefore, it is of vital importance to evaluate the potential pollutants generated from these docks and propose ways to eliminate those problems. A survey that asked about the carbon footprint and the quality of the water in the water footprint calculation was created and distributed to the management of the marinas’ operations. After receiving the completed surveys, the data were analyzed and translated using emission factors into …
