Supervisees' and supervisors' experiences of group climate in group supervision in psychotherapy. Effects of admission procedure

The purpose of this study was to evaluate the effects of two different admission procedures (high school grades/scholastic aptitude test (SAT) versus high school grades/SAT + interview) to a program in professional psychology on students' and supervisors' experiences of the group climate in psychotherapy supervision groups during an eighteen-month clinical practicum. A self-rating scale constructed to measure experiences of group climate in group supervision in psychotherapy was used. The results showed that students who were admitted based on the alternative admission procedure reported that their supervision groups had a more beneficial climate compared to those who were admitted based on high school grades/SAT. The evaluation suggested that admission via interviews together with high school grades/SAT is a good alternative to traditional admission procedures

Sensitivity-based multistep MPC for embedded systems

In model predictive control (MPC), an optimization problem is solved every sampling instant to determine an optimal control for a physical system. We aim to accelerate this procedure for fast systems applications and address the challenge of implementing the resulting MPC scheme on an embedded system with limited computing power. We present the sensitivity-based multistep MPC, a strategy which considerably reduces the computing requirements in terms of floating point operations (FLOPs), compared to a standard MPC formulation, while fulfilling closed- loop performance expectations. We illustrate by applying the method to a DC-DC converter model and show how a designer can optimally trade off closed-loop performance considerations with computing requirements in order to fit the controller into a resource-constrained embedded system

Localization of an endogenous lectin in chicken liver, intestine, and pancreas.

Extracts of adult chicken liver, pancreas, and intestine contain high levels of a lectin which appears to be identical to one previously purified from embryonic chick muscle. This lectin is virtually absent from adult muscle, but is highly concentrated in cells lining liver sinusoids, intestinal goblet cells, and the extracellular spaces surrounding pancreatic acini. These findings suggest that the lectin may play different roles in different tissues and at different times in the life of a chicken

Quantization in Control Systems and Forward Error Analysis of Iterative Numerical Algorithms

The use of control theory to study iterative algorithms, which can be considered as dynamical systems, opens many opportunities to find new tools for analysis of algorithms. In this paper we show that results from the study of quantization effects in control systems can be used to find systematic ways for forward error analysis of iterative algorithms. The proposed schemes are applied to the classical iterative methods for solving a system of linear equations. The obtained bounds are compared with bounds given in the numerical analysis literature

EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF); Scientific Opinion on Flavouring Group Evaluation 204 (FGE.204): Consideration of genotoxicity data on representatives for 18 mono-unsaturated, aliphatic, α,β-unsaturated ketones and precursors from chemical subgroup 1.2.1 of FGE.19 by EFSA

The Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids of the European Food Safety Authority was requested to evaluate the genotoxic potential of 18 flavouring substances from subgroup 1.2.1 of FGE.19 in the Flavouring Group Evaluation 204. The Flavour Industry provided additional genotoxicity studies for two representative substances, 4-methylpent-3-en-2-one [FL-no: 07.101] and 7-methyl-3-octenone-2 [FL-no: 07.177], which were evaluated in this FGE.204. Based on these new data, the Panel concluded that the flavouring substance [FL-no: 07.101] does not present a safety concern with respect to genotoxicity and accordingly it can be evaluated using the Procedure. On the contrary, the Panel could not conclude on the in vivo genotoxicity of [FL-no: 07.177] and more appropriate in vivo genotoxicity tests, considering also first site of contact, should be performed. In addition, the substance 4-methyl-3-hepten-5-one [FL-no: 07.261] was now identified as a substance for which no representative substances could be identified in the present FGE, resulting in a need for additional data on the genotoxic potential of this flavouring substance. However, the Panel noted that the 2-methyl substituted α,β-unsaturated aldehydes in FGE.201Rev1 can be considered as structurally related to [FL-no: 07.261]. Thus, the final conclusion on [FL-no: 07.261] will be drawn based on the outcome of the evaluation of FGE.201Rev1
