European Association for the Study of the Liver Hepatocellular Carcinoma summit 2014: old questions, new (or few) answers?
2014
, the European Association for the Study of the Liver (EASL) organized the 2014 EASL HCC Summit in Geneva, Switzerland from 13 to 16 February 2014. A number of interesting issues on the management of hepatocellular carci-noma (HCC) have been addressed during this meeting. However, our feeling is that only few answers have been given to those questions, mainly because of the still poor knowledge of the molecular basis and the natural history of HCC.HCC is a complex disease, associated in the wide majority of cases with under -lying cirrhosis. In addition, HCC pre-sents with high heterogeneity
On multi-scale percolation behaviour of the effective conductivity for the lattice model
2015
Macroscopic properties of heterogeneous media are frequently modelled by regular lattice models, which are based on a relatively small basic cluster of lattice sites. Here, we extend one of such models to any cluster's size kxk. We also explore its modified form. The focus is on the percolation behaviour of the effective conductivity of random two- and three-phase systems. We consider only the influence of geometrical features of local configurations at different length scales k. At scales accessible numerically, we find that an increase in the size of the basic cluster leads to characteristic displacements of the percolation threshold. We argue that the behaviour is typical of materials, w…
The Development of the Dealing with Challenging Interaction (DCI) Method to Evaluate Teachers’ Social Interaction Skills
2012
The Dealing with Challenging Interaction (DCI) method was developed to measure social interaction skills of teacher study groups. The participants were 70 teachers from three schools. The inter-rater agreement, Cohen’s kappa, varied between 0.57- 1.00. The discriminant validity was supported by a cluster analysis differentiating between the skilful and less skilful teachers. The results of the supplementary instrument were equivalent to the cluster analysis maintaining criterion oriented validity of the method developed. The DCI appeared to be a reliable and valid tool for measuring teachers’ social interaction skills. Peer reviewed
Group supervision: topics, process and outcome
2009
Supervision has been defined as “a formal process of professional support and learning which enables individual practitioners to develop knowledge and competence, assume responsibility for their own practice and enhance consumer protection and safety of care in complex clinical situations” ( Department of Health (DoH), 1993). The study analyzes topics, process and outcome of a Leader-Led Peer Group Supervision, inside a TC for psychiatric patients. The group was head by an expert group-analyst, whose role was not to solve the supervisee's clinical problems, but to work with supervisees to help them to develop and manage their practices (Mackereth, 1997). The research project aims to recogni…
Global, regional, and national burden of chronic kidney disease, 1990–2017: a systematic analysis for the Global Burden of Disease Study 2017
2020
Abstract: Background Health system planning requires careful assessment of chronic kidney disease (CKD) epidemiology, but data for morbidity and mortality of this disease are scarce or non-existent in many countries. We estimated the global, regional, and national burden of CKD, as well as the burden of cardiovascular disease and gout attributable to impaired kidney function, for the Global Burden of Diseases, Injuries, and Risk Factors Study 2017. We use the term CKD to refer to the morbidity and mortality that can be directly attributed to all stages of CKD, and we use the term impaired kidney function to refer to the additional risk of CKD from cardiovascular disease and gout. Methods Th…
Determination of consensus kQ values for megavoltage photon beams for the update of IAEA TRS-398
2020
The IAEA is currently coordinating a multi-year project to update the TRS-398 Code of Practice for the dosimetry of external beam radiotherapy based on standards of absorbed dose to water. One major aspect of the project is the determination of new beam quality correction factors, kQ, for megavoltage photon beams consistent with developments in radiotherapy dosimetry and technology since the publication of TRS-398 in 2000. Specifically, all values must be based on, or consistent with, the key data of ICRU Report 90. Data sets obtained from Monte Carlo (MC) calculations by advanced users and measurements at primary standards laboratories have been compiled for 23 cylindrical ionization chamb…
How team feedback and team trust influence information processing and learning in virtual teams: A moderated mediation model
2015
We study how team feedback influences information processing and learning in virtual teams.Group information is positively related to team learning in virtual teams.The indirect effect of team feedback on team learning via group information elaboration is moderated by team trust. This study examines a moderated mediation model in which team trust moderates the indirect effect of team feedback on team learning through group information elaboration in virtual teams. An experimental study in a laboratory was conducted with 54 teams randomly assigned to a team feedback condition or a control condition. Results provided empirical support to the moderated mediation model. We found that the indire…
The effects of virtuality level on task-related collaborative behaviors: The mediating role of team trust
2013
This study aims to analyze the mediating role of team trust in the relationship between virtuality level and task-related collaborative behaviors. Three types of task-related collaborative behaviors were studied, namely team coordination, team cooperation, and team information exchange. Drawing upon theory and research on virtual teams and trust, we hypothesized that team trust partially mediated the effects of virtuality level on team coordination, team cooperation, and team information exchange. A laboratory experiment was carried out with 65 four-person teams randomly assigned to three communication media with different virtuality levels (face-to-face, video conference and computer-media…
Interdependence between best team members and their teammates
2013
PurposeThe purpose of this paper is to examine how, within a team, the value of their best member depends critically on the performance of the rest. Analysis of the interdependent team members complements the traditional focus of resource‐based‐view analyses of isolated resources.Design/methodology/approachThe authors used data from 584 National Basketball Association teams (30 teams collected over 21 seasons).FindingsThe authors find a positive relationship between best member performance and team performance that increases as the rest of the team members’ performance improves.Practical implicationsHaving team members with a high individual performance does not imply that the team will hav…
Testing relations between group cohesion and satisfaction in project teams: A cross-level and cross-lagged approach
2014
Based on a two-dimensional perspective of group cohesion, this study examines the emergence of task cohesion and interpersonal cohesion in project teams and their roles in changes in members’ individual satisfaction with the team. Specifically, we tested a direct-effect and mediation model of the cross-level relationship between team task and interpersonal cohesion and individual satisfaction with the team over time. With a sample of 74 newly created project teams, the hypotheses were tested using a two-wave panel design. Results indicate that task cohesion emerges more strongly than interpersonal cohesion during the first stages of work in project teams. Moreover, the cross-lagged relation…
