Mechanisms linking authentic leadership to emotional exhaustion: The role of procedural justice and emotional demands in a moderated mediation approa…
2016
In order to gain more knowledge on how the positive leadership concept of authentic leadership impacts follower strain, this study tries to uncover procedural justice as an underlying mechanism. In contrast to previous work, we exclusively base our theoretical model on justice theories. Specifically, we hypothesize that authentic leadership negatively predicts emotional exhaustion through perceptions of procedural justice. We assume that this indirect effect is conditional on followers’ amount of emotional demands, and that the procedural justice-emotional exhaustion relationship is stronger when emotional demands are high. This finally results in a stronger exhaustion-reducing effect of au…
Between a Rock and Hard Place: Combined Effects of Authentic Leadership, Organizational Identification, and Team Prototypicality on Managerial Prohib…
2019
AbstractManagers are installed by the organization’s stakeholders and shareholders to increase the organization’s value; at the same time, they depend on their subordinates’ acceptance to fulfill this leadership role. If the interest of the organization collides with the interest of their team, some managers act in the interest of their followers accepting potential disadvantages for their organizations and/or external stakeholders. In two experimental studies comprised mainly of German (N = 111) and US (N = 323) managers, we examined combined effects of authentic leadership, organizational identification, and self-perceived team prototypicality on managerial integrity operationalized as ex…
Archaeometric Study of Two Tanagra Type Statuettes of Unknown Provenance to Support Forensic Study
2022
This paper is concerned with a morphological-stylistic and archaeometric study of two small pottery statues, confiscated by the Cosenza Carabinieri Unit for the Protection of Cultural Heritage and Anti-Counterfeiting (Calabria, Italy). The research aimed to establish the authenticity of the artworks and to verify a possible origin from the same workshop manufacturing, by providing indications about the textural features and raw materials used for their production. For these purposes, the analytical approach involved the use of minero-petrographic and physical analysis, as follows: petrographic analysis (OM), X-ray diffraction (XRD) and thermoluminescence tests (TL). The preliminary observat…
Educazione autentica, coscienze prepedagogica, pedagogia spontanea nel progetto metodico di una "pedagogia fondamentale"
2012
L’approccio di una pedagogia metodicamente strutturata permette di indagare in profondità i fenomeni educativi, poiché ne coglie la realtà oggettiva che rivela aspetti importanti del modo di essere nel mondo proprio dell’educando e dell’educatore, e che prospetta il loro autentico poter essere. L’educazione intesa come esperienza vissuta nella relazione interpersonale è infatti una realtà complessa, che per essere compresa adeguatamente richiede approcci disciplinari, logiche e linguaggi diversi. L’orizzonte di senso in cui la questione “pedagogica” dell’educazione autentica si presenta è l’esperienza quotidiana dell’educatore e dell’educando. La coscienza non edotta dal sapere pedagogico ―…
The moderator role of followers’ personality traits in the relations between leadership styles, two types of task performance and work result satisfa…
2014
Authentic leadership is changing our understanding of what makes good leadership. However, few studies have explored how followers’ individual differences and the nature of the task they perform affect its relation to followers’ work outcomes. We examine the moderator role of two core task types (intellective vs. generative) and two personality traits (conscientiousness and emotional stability) in the relationship between two leadership feedback styles (authentic vs. transactional) and task performance or work result satisfaction in a two-wave experiment. The sample consisted of 228 participants enrolled in an organizational psychology course, 34% of whom had work experience. Our results sh…
VIRTUOSIDAD EN ORGANIZACIONES ESCOLARES ASOCIADA AL LIDERAZGO AUTÉNTICO DE SUS AUTORIDADES
2020
espanolEl presente estudio se realizo en el marco de un ejercicio de reflexion sobre los elementos que contribuyen a fortalecer la calidad de la educacion en Ecuador , desde el accionar de autoridades, docentes y estudiantes; su marco teorico de analisis fue la Psicologia Positiva aplicada a la escuela como organizacion virtuosa. El objetivo fue identificar perfiles de or ganizaciones escolares percibidas como virtuosas, asociados a los niveles de liderazgo autentico presentes en sus autoridades. Se trabajo con una muestra no probabilistica de 209 autoridades educativas mediante la aplicacion de las escalas de virtuosidad p ercibida en organizaciones escolares y liderazgo autentico, en auto…
Authentication of phacelia honeys (Phacelia tanacetifolia) based on a combination of HPLC and HPTLC analyses as well as spectrophotometric measuremen…
2019
Abstract The growing interest in the quality of honey affects customer preferences and consumption trends. Generally, monofloral honeys are more expensive than multifloral honeys, and the price strictly depends on its botanical origin. The increasing popularity of a variety of monofloral brands has led to the increasing number of adulterations and therefore for the need to develop new analytical methods for assessing honey authenticity. The purpose of the present study was to develop a method for the authentication of phacelia honeys on the basis of HPLC and HPTLC analyses and spectrophotometry. The results obtained by spectrophotometric analysis indicated significant differences only betwe…
Fingerprint Quality Evaluation in a Novel Embedded Authentication System for Mobile Users
2015
The way people access resources, data and services, is radically changing using modern mobile technologies. In this scenario, biometry is a good solution for security issues even if its performance is influenced by the acquired data quality. In this paper, a novel embedded automatic fingerprint authentication system (AFAS) for mobile users is described. The goal of the proposed system is to improve the performance of a standard embedded AFAS in order to enable its employment in mobile devices architectures. The system is focused on the quality evaluation of the raw acquired fingerprint, identifying areas of poor quality. Using this approach, no image enhancement process is needed after the …
Analyzing the security of Windows 7 and Linux for cloud computing
2013
We review and analyze the major security features and concerns in deploying modern commodity operating systems such as Windows 7 and Linux 2.6.38 in a cloud computing environment. We identify the security weaknesses and open challenges of these two operating systems when deployed in the cloud environment. In particular, we examine and compare various operating system security features which are critical in providing a secure cloud. These security features include authentication, authorization and access control, physical memory protection, privacy and encryption of stored data, network access and firewalling capabilities, and virtual memory.
Machine Learning VS Transfer Learning - Smart Camera Implementation for Face Authentication
2018
The aim of this paper is to highlight differences between classical machine learning and transfer learning applied to low cost real-time face authentication. Furthermore, in an access control context, the size of biometric data should be minimized so it can be stored on a remote personal media. These constraints have led us to compare only lightest versions of these algorithms. Transfer learning applied on Mobilenet v1 raises to 85% of accuracy, for a 457Ko model, with 3680s and 1.43s for training and prediction tasks. In comparison, the fastest integrated method (Random Forest) shows accuracy up to 90% for a 7,9Ko model, with a fifth of a second to be trained and a hundred of microseconds …
