Mechanical evaluation for three-dimensional printed orthodontic springs with different heights-in vitro study
2021
Background The orthodontic spring materials in use have a significant influence on the applied forces. The prerequisite to identify the in vitro< force deflection of the CAD/CAM fabricated springs is considered mandatory to identify the material characteristics. The purpose of the present investigation was to evaluate the mechanical load on 3D printed springs using different coil heights. Material and Methods The springs were digitally designed with different coil heights using Autodesk Netfabb CAD software (San Rafael, CA, USA). Test specimens were manufactured using 3D printable experimental flexible material (Code: BM2008, GC, Tokyo, Japan). The specimens were divided according to the co…
Shear force comparative evaluation for surface treated and non- treated 3D interim printed materials with different types of glass-ionomer cements
2020
Background The purpose of this investigation was to compare shear force of different glass-ionomer cements on 3D printed interim material in combination with and without surface pretreatment. Material and Methods 120 rectangular specimens made of printable provisional material (Bego, Bremen, Germany) were used. After post-processing the specimens were blasted with aluminum oxide 110µm (Bego, Bremen, Germany). Extra 120 non-surface treated specimens were used as an experimental negative test group. All 240 specimens were divided randomly into 6 groups. All were cemented with a compressive load of 20 N using universal testing machine Z010 (Zwick/Roell, Ulm, Germany) to ensure a comparable cem…
Study on the Linezolid Prescription According to the Approval of Indication in a University Hospital.
2015
Indications for linezolid use are nosocomial or community-acquired pneumonia and skin infections or soft tissue infection caused by gram-positive microorganisms, but new recommendations may emerge. It is important to balance benefits with risks because severe adverse events have been described in patients taking linezolid treatment. Accordingly, we evaluated the suitability of linezolid prescription according to approval of indication by evaluating the presence of drug-related problems (DRP) in a University hospital. DRP were identified in 36 patients (50.0%). In most cases, they were related to known or established indications (15 patients, 20.8%), to safety (5 patients, 6.9%), and to both…
Shame On You! Unpacking the Individual and Organizational Implications of Engaging with a Stigmatized Organization
2021
How and when does engagement with a stigmatized organization lead to the transfer of its stigma to organizations and individuals associating with it? To answer this question, we conduct an inductive study of the process of stigma transfer and the conditions determining social actors’ susceptibility to such courtesy stigma. We build our process model using interview and archival data on two art exhibitions engaging with Hells Angels Motorcycle Club (HAMC) Norway. Our study identifies purposeful shaming as a key element in the stigma transfer process, and shows that shaming attempts take on different forms at the individual and organizational levels. We also illustrate that contestation of sh…
Spatial and economic segregation : an analysis in terms of employment and education in urban spaces
2016
Cities are not homogeneous territories: some neighborhoods concentrate wealth while others face difficulties such as unemployment, poverty, exclusion or crime. These fractures are a consequence of urban segregation, i.e. socioeconomic inequalities spatial pattern. To that matter, this thesis addresses three objectives: (i) the characterization and explanation of segregated urban structures appearance, (ii) the link between segregation and labor market, and eventually (iii) the link between segregation and education. According to Urban Economics, the urban structure influences individual’s employment status through the distance to jobs. This hypothesis is tested via an empirical study on the…
Giustizia ambientale e recupero delle aree verdi: il caso di Palermo
2021
L’urban shrinkage è diventata una questione centrale tanto nel dibattito scientifico quanto nell’agenda politica di diverse città europee. Secondo i dati EUROSTAT (2019), circa il 40% delle città europee con più di 200.000 abitanti stanno perdendo popolazione; una contrazione che si esplicita maggiormente, sotto il profilo spaziale, in una progressiva sottoutilizzazione del patrimonio edificato, così come nel contestuale incremento di aree e terreni in stato di abbandono. In questo quadro controverso di mutazione strutturale della città, così come l’abbiamo conosciuta, le politiche urbane alla prova in Europa tentano di declinare la decrescita quale occasione strategica di investimento sull…
Análisis y validación de una rúbrica para evaluar habilidades de presentación oral en contextos universitarios
2017
Introducción. Este trabajo analiza la validez convergente entre la evaluación sumativa de las habilidades de comunicación oral con apoyo visual de estudiantes universitarios efectuada por el profesorado y por los pares a través de la aplicación de una rúbrica.Método. Se analiza el nivel de convergencia entre las valoraciones efectuadas por el profesorado y por los pares desde una perspectiva analítica –criterio a criterio- y holística –puntuación global-. La percepción de validez y utilidad se determina a partir de las valoraciones efectuadas por los estudiantes sobre ambos aspectos en relación a la rúbrica desarrollada.Resultados. Los estudiantes señalan que la rúbrica resulta útil para ex…
Collaborative Content Downloading in VANETs with Fuzzy Comprehensive Evaluation
2019
Vehicle collaborative content downloading has become a hotspot in current vehicular ad-hoc network (VANET) research. However, in reality, the highly dynamic nature of VANET makes users lose resources easily, and the transmission of invalid segment data also wastes valuable bandwidth and storage of the users&rsquo
The Complexity of Value and the Evaluation of Complexity: Social Use Value and Multi-criteria Analysis
2018
The “challenge of complexity” is one of the many points of convergence between the Encyclical Laudato si’ and the evolution of post-modern scientific thought. This study aims to analyze how complexity represents the essential element of the profound renewal in the scientific paradigm of the discipline of evaluation, particularly in regard to the theory of value, the categories of value, and the instruments of multi-criteria evaluation. Some contemporary theories of value propose, in fact, a complex source of value, such as surpluses of energy and of information (Ecological Economics) or as the creative and synergistic combination of three surpluses, namely energetic and non-entropic, geneal…
Sports clubs as settings for health promotion: fundamentals and an overview to research.
2014
This paper explores the efficacy and value of sports clubs as a setting for health promotion. Sports clubs for children and adolescents are the primary focus of the paper, and the aims are two-fold. Aims: Firstly, the paper aims to review the basis for and elements of the health promoting sports club (HPSC) concept. Secondly, the aim is to overview the international evolution of the HPSC concept and its usefulness in the research. The settings-based health promotion approach forms the basis for the HPSC concept and it is introduced first. Thereafter, both obligating and prospecting factors, to justify the importance for sports clubs to address health promotion, are expressed. Major prospec…
