White Counselor Trainees\u27 Racial Identity and Working Alliance Perceptions

Racial identity has been theorized to significantly affect cross-racial counseling relationships (Helms, 1984, 1995). This study examined the direct impact of White racial identity of 124 counselor trainees on working alliance formation in a same-racial and cross-racial vicarious counseling analogue. Regardless of the race of the client, disintegration and reintegration attitudes negatively affected working alliance ratings, and pseudoindependent and autonomy attitudes positively affected working alliance ratings. Implications for counseling, supervision, training, and research are discussed

Mathematical Programming Models for Annual and Weekly Bloodmobile Collection Planning

International audienceIn this paper, we propose a two-step bloodmobile collection planning framework. The first step is the annual planning to determine weeks of collection at each mobile site in order to ensure regional self-sufficiency of blood supply. The second step is the detailed weekly planning to determine days of collections at each mobile site and to form corresponding transfusion teams. Only key resource requirements are considered for annual planning while detailed resource requirements and transportation times are considered for weekly planning. Two Mixed Integer Programming models are proposed for annual planning by assuming fixed or variable mobile collection frequencies. A new donation forecast model is proposed based on population demographics, donor generosity, and donor availability. A new concept of bloodmobile collection configurations is proposed for compact and efficient mathematical modeling of weekly planning in order to minimize the total working time. Field data from the French Blood Service (EFS) in the Auvergne-Loire Region are used to design numerical experiments and to assess the efficiency of the proposed models

Modelling and simulation of blood collection systems: improvement of human resources allocation for better cost-effectiveness and reduction of candidate donor abandonment

International audienceFormal Petri net models were used to describe all relevant donor flows of the various blood collection systems; the Petri net models were converted onto discrete-event simulation models, allowing the evaluation of a large number of scenarios and configurations of blood collection systems. Quantitative models were proposed that encompassed all components of the blood collection systems, such as the donor arrival process, resource capacities and performance indicators. Appropriate experimental designs and cost-effectiveness analyses were used to determine the best configurations of human resources and donor appointment strategies

Fault Investigation of Circulation Pumps to Detect Impeller Clogging

[EN] Pumps have a wide range of applications. Methods for fault detection of motors are increasingly being used for pumps. In the context of this paper, a test bench is built to investigate circulation pumps for faults. As a use case, the fault of impeller clogging was first measured and then examined with the help of motor current signature analysis. It can be seen that there are four frequencies at which there is an increase in amplitude in case of a fault. The sidebands around the supply frequency are in particular focus. The clogging of three and four of a total of seven channels leads to the highest amplitudes at the fault frequencies. The efficiency is reduced by 9 to 15% in case of faulty operation. These results indicate that the implementation of fault detection algorithms on the pump electronics represents added value for the pump operator. Furthermore, the results can be transferred to other applications.This research was funded by the German Federal Ministry for Economic Affairs an Energy , grant number 03ET1613B.Becker, V.; Schwamm, T.; Urschel, S.; Antonino-Daviu, JA.

Assessing Social-Emotional Abilities of Preschool-Aged Children Within a Social-Emotional Learning Framework

During the past decade, there has been an increasing amount of research demonstrating a positive relationship between early childhood social-emotional abilities and later life outcomes. As such, practitioners who work with preschool-aged children are called to understand the social-emotional abilities that constitute healthy development. Doing so provides practitioners with a social-emotional framework from which to work so that they may efficiently assess and intervene in these abilities. This manuscript grounds social-emotional abilities within the Collaborative for Academic, Social, and Emotional Learning’s (CASEL) Framework for Social-Emotional Learning (SEL). We describe the need for a multi-method, multi-sourced, multi-setting comprehensive social-emotional assessment of preschool-aged children and describe a rating scale that can be used as a part of the assessment process. The manuscript concludes with a discussion regarding the importance of intervening early to prepare preschool-aged children for future academic and life success

Microprocessor error diagnosis by trace monitoring under laser testing

This work explores the diagnosis capabilities of the enriched information provided by microprocessors trace subsystem combined with laser fault injection. Laser fault injection campaigns with delimited architectural regions have been accomplished on an ARM Cortex-A9 device. Experimental results demonstrate the capability of the presented technique to provide additional information of the various error mechanisms that can happen in a microprocessor. A comparison with radiation campaigns presented in previous work is also discussed, showing that laser fault injection results are in good agreement with neutron and proton radiation results

Analysis of a stabilized finite element method for fluid flows through a porous interface

International audienceThis work is devoted to the numerical simulation of an incompressible fluid through a porous interface, modeled as a macroscopic resistive interface term in the Stokes equations. We improve the results reported in [M2AN, 42(6):961-990, 2008], by showing that the standard Pressure Stabilized Petrov-Galerkin (PSPG) finite element method is stable, and optimally convergent, without the need for controlling the pressure jump across the interface

Projection schemes for fluid flows through a porous interface

International audienceThis paper presents a numerical method to simulate an incompressible fluid through an immersed porous interface. The interface is modeled by a surface measure term in the Navier-Stokes equations and it is characterized by a resistance parameter. This approach can be used for example to model valves or to simulate blood flood through an immersed stent. Starting from a monolithic formulation proposed recently, a fractional step algorithm is derived. The difficult point is that this formulation is singular when the resistance vanishes, which can be a serious issue in some applications. We show that an appropriate Nitsche's treatment of the interface condition fixes this problem and ensures uniform energy stability in time, for any non-negative value of the resistance. The theoretical stability and convergence results are illustrated with numerical experiment

SPECTRE: a Suite of PhylogEnetiC Tools for Reticulate Evolution

Split-networks are a generalization of phylogenetic trees that have proven to be a powerful tool in phylogenetics. Various ways have been developed for computing such networks, including split-decomposition, NeighborNet, QNet and FlatNJ. Some of these approaches are implemented in the user-friendly SplitsTree software package. However, to give the user the option to adjust and extend these approaches and to facilitate their integration into analysis pipelines, there is a need for robust, open-source implementations of associated data structures and algorithms. Here we present SPECTRE, a readily available, open-source library of data structures written in Java, that comes complete with new implementations of several pre-published algorithms and a basic interactive graphical interface for visualizing planar split networks. SPECTRE also supports the use of longer running algorithms by providing command line interfaces, which can be executed on servers or in High Performance Computing (HPC) environments
