Effects of Group Formation on Student Satisfaction and Performance: A Field Experiment

2021

This study analyzes the relation of group formation on outcomes of a 4-week online course for prospective students. Group formation was experimentally manipulated based on predefined criteria, personality traits conscientiousness and extraversion. As research questions, groups were considered advantageous if they were formed (a) heterogeneously in extraversion, and (b) homogeneously in conscientiousness. As a result, no uniform outcome was identified. Most variance could be explained on group level, but no significant main effect for experimental grouping was found. Significant interaction between both main effects hint that the results do not provide final answers, but guidance for furthe…

Effectiveness of interceptive treatment of class III malocclusions with skeletal anchorage: A systematic review and meta-analysis

2017

Recently, new strategies for treating class III malocclusions have appeared. Skeletal anchorage appears to reduce the dentoalveolar effects while maximising the orthopaedic effect in growing patients. The purpose of this systematic review and meta-analysis is to examine the effectiveness of bone anchorage devices for interceptive treatment of skeletal class III malocclusions. Searches were made in the Pubmed, Embase, Scopus and Cochrane databases, as well as in a grey literature database, and were complemented by hand-searching. The criteria for eligibility were: patients who had undergone orthodontic treatment with skeletal anchorage (miniplates and miniscrews). Patients with syndromes or …

Terminology and French-Spanish business translation: evaluating terminology resources for the translation of accounting documents

2014

This article is the English version of “Terminología y traducción económica francés-español: evaluación de recursos terminológicos en el ámbito contable” by Daniel Gallego Hernández. It was not published on the print version of MonTI for reasons of space. The online version of MonTI does not suffer from these limitations, and this is our way of promoting plurilingualism. The aim of this paper is to evaluate a series of terminology resources and determine their suitability to the practice of French-Spanish translation of accounting documents. First we identify the terminology needs of a specific group of translator trainees when facing business translation, as well as the resources they use …

2016

The laparoscopic approach to Acute Mesenteric Ischemia is today unclear and less debated (AMI). There are in fact no clinical evidences on this particular focus and only few articles can be found in several databases (pubmed, cochrane library, etc.), and the problem concerns both diagnostic and therapeutic utilization of the procedure. These considerations were already taken into account in 2012 EAES guidelines where the Grade of Recommendation (GoR) of laparoscopy in AMI was low in both diagnostic and therapeutic aspects. According to the new Oxford Classification [1], the use of laparoscopy in patients with suspicious or diagnosed AMI presents a weak GoR.

Una nuova acquisizione iconografica per la ricostruzione della tribuna di Antonello Gagini nella Cattedrale di Palermo

2022

La recente digitalizzazione di un dipinto di anonimo siciliano nelle collezioni del Museo de Historia di Madrid e il suo inserimento nei database del patrimonio culturale spagnolo ed europeo ha consentito di riportare all’attenzione della comunità scientifica un’importante raffigurazione pittorica della tribuna di Antonello Gagini nella Cattedrale di Palermo. Dopo avere ripercorso le principali fonti documentarie ed iconografiche relative alla tribuna, viene qui presentata l’opera oggi a Madrid, che fornisce un prezioso riscontro alle fonti fin qui note.

Distributed Data Clustering via Opinion Dynamics

2015

We provide a distributed method to partition a large set of data in clusters, characterized by small in-group and large out-group distances. We assume a wireless sensors network in which each sensor is given a large set of data and the objective is to provide a way to group the sensors in homogeneous clusters by information type. In previous literature, the desired number of clusters must be specified a priori by the user. In our approach, the clusters are constrained to have centroids with a distance at least ε between them and the number of desired clusters is not specified. Although traditional algorithms fail to solve the problem with this constraint, it can help obtain a better cluste…

An improved quantum query algorithm for computing AND Boolean function

2010

We consider the quantum query model for computing Boolean functions. The definition of the function is known, but a black box contains the input X = (x 1 , x 2 , …, x n ). Black box can be accessed by querying x i values. The goal is to develop an algorithm, which would compute the function value for arbitrary input using as few queries to the black box as possible. We present two different quantum query algorithms for computing the basic Boolean function — logical AND of two bits. Both algorithms use only one query to determine the function value. Correct answer probability for the first algorithm is 80%, but for the second algorithm it is 90%. To compute this function with the same probab…

Robust Synchronization-Based Graph Clustering

2013

Complex graph data now arises in various fields like social networks, protein-protein interaction networks, ecosystems, etc. To reveal the underlying patterns in graphs, an important task is to partition them into several meaningful clusters. The question is: how can we find the natural partitions of a complex graph which truly reflect the intrinsic patterns? In this paper, we propose RSGC, a novel approach to graph clustering. The key philosophy of RSGC is to consider graph clustering as a dynamic process towards synchronization. For each vertex, it is viewed as an oscillator and interacts with other vertices according to the graph connection information. During the process towards synchro…
