REFLECTIONS ON MANAGERIAL COMMUNICATION
2012
Modern management has given an extremely important place to managerial communication. It considers communication as a vital component of the managerial system of all organizations. A successful manager is the one that can communicate with the persons that he or she is leading, and the performance of an organization can be conditioned by the manner in which managers communicate. The identification of employees with the organizational goals, their channeling of efforts for the common objectives, the ability of the manager to assess the results of his or her decisions can be accomplished only by using the resources of managerial communication. A laconic, delayed or confused managerial communic…
Evaluation of lens absorbed dose with Cone Beam IGRT procedures
2015
The purpose of this work is to evaluate the absorbed dose to the eye lenses due to the cone beam computed tomography (CBCT) system used to accurately position the patient during head-and-neck image guided procedures. The on-board imaging (OBI) systems (v.1.5) of Clinac iX and TrueBeam (Varian) accelerators were used to evaluate the imparted dose to the eye lenses and some additional points of the head. All CBCT scans were acquired with the Standard-Dose Head protocol from Varian. Doses were measured using thermoluminescence dosimeters (TLDs) placed in an anthropomorphic phantom. TLDs were calibrated at the beam quality used to reduce their energy dependence. Average dose to the lens due to …
Dental CBCT equipment and performance issues
2012
Dental cone beam computed tomography (CBCT), also known as digital volumetric tomography was developed in the late 1990s and is now increasingly available in clinical practice. It can provide high resolution cross-sectional images of teeth and the maxillofacial region with applications in all branches of dentistry. As a new imaging modality, there were no established suspension levels at a European level. A literature review, encompassing scientific, professional publications and existing national guidelines was performed in an attempt to develop a set of suspension levels for dental CBCT, using additional expert opinion from the members of the European Academy of dento-maxillo-facial radio…
Radiation dose in non-dental cone beam CT applications: a systematic review.
2018
Background: Radiation-induced health risks are broadly questioned in the literature. As cone beam computed tomography (CBCT) is increasingly used in non-dental examinations, its effective dose needs to be known. This study aimed to review the published evidence on effective dose of non-dental CBCT for diagnostic use by focusing on dosimetry system used to estimate dose. Materials and methods: A systematic review of the literature was performed on 12 November 2017. All the literature up to this date was included. The PubMed and web of science databases were searched. Studies were screened for inclusion based on defined inclusion and exclusion criteria according to the preferred reporting ite…

Relations entre le système de consommation et les comportements en magasin : une approche par la valeur : application au vêtement
2011
Within the course of the theory of cultural consumption (CCT), this research aims to enlighten on the relationship between the consumer to hir or her system of consumption. The first part, qualitative, attempts to describe the nature of the relationship between the consumer and his or her system (the wardrobe in our case) through an anthropological study and a semiotic study. The data was collected by way of observation (video and audio taped) during usage experiences. The second part, quantitative, measures separately the sedimentation of value linked to usage and shopping experiences. Applied to the clothing market, results show the value of the organisational and systemic concerns (which…
Cambios de Identidad asociados a la vivencia de una transición ritualizada: aprobar una oposición
2008
This qualitative research study depicts the main categories obtained by means of an inductive methodology based on the content analysis of 8 interviews using the N’Vivo program. The sample consisted of 8 men (between 26 and 45 years) who had passed a competitive examination. We take into consideration whether this life event and its related transition is an example of a contemporary rite of passage. We focus on changes reported by the subjects once the developmental transition was over. These changes are related to new social identities. The most relevant psychological and structural processes in order to get this kind of optimal changes are also discussed.
A Study of Computer Science Students' Ethical Attitudes and Its Implications to
2003
In this study I investigated 198 Finnish computer science students' attitudes concerning computer usage and professional practic e in computing to determine content for computer ethics education. Students were to analyse acceptability of individuals' behavi our in 23 cases. It is postulated that divergence of attitudes in cases lead students to present opposing viewpoints during smal l group discussions and thus to develop moral sensitivity and judgment in students. The following issues emerged in this study: cracking to computer systems, using a database of an employer for one's own purposes, honesty in client relationships, acknowled ging someone's contribution, keeping software without p…
Low dose CT of the heart: a quantum leap into a new era of cardiovascular imaging.
2010
In 10 years, computed tomography coronary angiography (CTCA) has shifted from an investigational tool to clinical reality. Even though CT technologies are very advanced and widely available, a large body of evidence supporting the clinical role of CTCA is missing. The reason is that the speed of technological development has outpaced the ability of the scientific community to demonstrate the clinical utility of the technique. In addition, with each new CT generation, there is a further broadening of actual and potential applications. In this review we examine the state of the art on CTCA. In particular, we focus on issues concerning technological development, radiation dose, implementation,…
CT coronary angiography at an ultra-low radiation dose (< 0.1 mSv): feasible and viable in times of constraint on healthcare costs
2013
Computed tomography coronary angiography (CTCA) has reached very high standards both in terms of diagnostic performance and radiation dose reduction. This commentary follows a report on CTCA using less than 0.1 mSv in selected patients. This is an extraordinary accomplishment, both for technology and for medicine. The difficult task is now to implement this tool in clinical practice so it can play the best possible role. CTCA can improve diagnostic pathways, can save money for healthcare systems and could even improve pharmacological therapy. All of this may happen, but it will require the combined effort of all the experienced operators in this field, including the referring clinicians. In…
