“This is for the Children,the Grandchildren …”: Houses of Moroccan Immigrants in Metropolitan Tel Aviv

The meaning of migrant housing materiality has not been adequately researched, especially when compared to the meaning of the home for immigrants, a matter of extensive discussion in the past two decades. This paper focuses on the meaning of housing materiality for 12 immigrants who migrated from Morocco to Israel some 60?years ago. Drawing on qualitative data gathered in 2007 and 2008, the paper develops a theoretical framework considering “house as community” and “house materiality” as two interrelating explanations for the migrant housing materiality. Through this framework, and with the concepts of performance and performativity, the paper first explores former houses of participants in Morocco and then presents current houses in Tel Aviv, Israel, to establish links between the two housing forms and reveal the meanings of objects in the homes. It is argued that as a reaction to the dominant Israeli society, housing materiality enables participants to educate successive generations and Israeli society at large about the rich cultural life of Moroccan-Jews that existed before their migration to Israel.     

R&D networks and regional knowledge production in Europe: Evidence from a space‐time model

In this study we estimate space‐time impacts of the embeddedness in R&D networks on regional knowledge production using a dynamic spatial panel data model with non‐linear effects for 229 European NUTS 2 regions in the period 1998–2010. Embeddedness refers to the positioning in networks where nodes represent regions that are linked by joint R&D projects funded by EU Framework Programmes. We find evidence that increasing embeddedness in EU funded R&D networks leads to positive immediate impacts on regional knowledge production, and that regions with lower levels of own knowledge endowments more likely exploit the positive effects. However, the long‐term impacts of a region's embeddedness in these R&D networks are comparatively small.     

3D Printing Thermally Stable High-Performance Polymers Based on a Dual Curing Mechanism

High-performance polymers are an important class of materials that are used in challenging conditions, such as in aerospace applications. Until now, 3D printing based on stereolithography processes can not be performed due to a lack of suitable materials. There is report on new materials and printing compositions that enable 3D printing of objects having extremely high thermal resistance, with Tg of 283 °C and excellent mechanical properties. The printing is performed by a low-cost Digital Light Processing printer, and the formulation is based on a dual-cure mechanism, photo, and thermal process. The main components are a molecule that has both epoxy and acrylate groups, alkylated melamine that enables a high degree of crosslinking, and a soluble precursor of silica. The resulting objects are made of hybrid materials, in which the silicon is present in the polymeric backbone and partly as silica enforcement particles.     

Traumatic memory characteristics: A cross-validated mediational model of response to rape among employed women.

In a cross-validated mediational model, the authors examined characteristics of memories formed in response to rape and other intense unpleasant and pleasant experiences. Data were responses to a mailed survey of women medical center and university employees. Measurement models of memory and symptom factors and a structural model with pathways among cognitive appraisal, emotional valence, memory characteristics, and health outcomes were developed in Sample I (N?=?1,307) and confirmed in Sample 2 (N?=?2,142). Rape had substantial direct effects on 2 memory factors (Clarity and Affect) and indirect effects through the construal of victimization. Rape was associated with memories described as more emotionally intense but less clear and coherent and less often thought of or talked about. Most effects on physical symptoms were nonsignificant. Implications of findings for neurohormonal and multiple representation models of emotional memory and to cognitive avoidance are discussed.

Through a narrow window: Sample size and the perception of correlation.

A theoretical analysis (Y. Kareev, 1995b) of the sampling distribution of correlations led to the surprising conclusion that the use of small samples has a potential advantage for the early detection of a correlation. This is so because the distribution is highly skewed, and the smaller the sample size, the more the distribution is skewed. This article describes 2 experiments that were designed as empirical tests of this conclusion. In Experiment 1 (N?=?112), the authors compared the predictions of participants differing in their working-memory capacity (hence in the size of the samples they were likely to consider). In Experiment 2 (N?=?144), the authors compared the predictions of participants who viewed samples of different sizes, whose size was determined by the authors. The results fully supported Y. Kareev's conclusion: In both experiments, participants with lower capacity (or smaller samples) indeed perceived the correlation as more extreme and were more accurate in their predictions.

An absolute calibration of the solid state detectors in the narrow band neutrino beam at CERN

A method to calibrate in an absolute way the solid state detectors that are used to monitor the muon flux in the (anti)neutrino beam line at the CERN SPS is described. This calibration is one way that opens the possibility to measure the (anti)neutrino flux needed for the determination of the absolute total cross-sections of (anti)neutrino-nucleon interactions. Tracks of charged particles are recorded simultaneously in the solid state detectors and in Ilford G5 emulsions. The readings of the detectors are compared with a count of the tracks in the developed emulsions. Absolute calibration factors (number of passing muons per delivered pC of electric charge) under particular circumstances are given. The overall accuracy that can be obtained is 3%.     

Influence of heat treatment on the mechanical properties of an Fe E 460 TMCP steel

Welding is always accompanied by a heat treatment of the base metal. The heat affected zone (HAZ) of multilayer welded joints often shows different microstructures along the fusion line due to varying heat treatments. In order to investigate the mechanical properties of single microstructures weld simulation treatment was applied. The influence of weld simulation parameters such as heating rate and peak temperature was checked in a preliminary step. Several weld simulation treatments finally were used to explain the behaviour of real welded joints. A comparison of fracture mechanics test results from weld simulated microstructures and from real HAZ's shows good agreement for equal heat treatment conditions.     

Home environment and development of slow-learning adolescents: Reciprocal relations.

Investigated the reciprocal relation between the home environment and the development of 148 7–14 yr old slow-learners longitudinally over a 3-yr period. Annual assessments of the home environment included childrearing attitudes, educationally relevant stimuli and opportunities, and psychosocial climate and environmental press of the home. Main caregivers (usually mothers) were administered the Henderson Environmental Learning Process Scale and the Family Environment Scale. Measures of the Ss' development included social competency, psychosocial adjustment, and self-concept. Partial correlation and hierarchical multiple regression analysis revealed significant influence of environmental stimulation, both cognitive and social, on the Ss' subsequent cognitive development and social adjustment. Harmony and quality of parenting, and educational expectation and aspiration were the 2 most salient environmental variables associated with the Ss' development. The study also demonstrated significant influence of the Ss' psychosocial adjustment on subsequent changes in the home environment including psychosocial climate of the home, family adjustment, and the parents' educational expectations and aspirations.
