Anxiety and hostility to an "outsider," as moderated by low perceived power

The hostile and anxious responses of young adults to an immigrant (vs. native-born) stranger were examined as a function of participants' self-perceived power. In Studies 1 and 2, individuals with low perceived social power (males, in particular) showed high anxiety toward an "outsider" but more so if that individual was an immigrant (and thus posed an ambiguous threat to their position in the hierarchy). In Study 3, young adult males competed on a reaction time test with an immigrant or native-born rival. With immigrant rivals, males with low perceived social power showed relatively high aggression toward an immigrant rival and derogation of the rival's formidability; however, they showed a more deferential pattern with native-born rivals.     

Strain rate response of a Ni–Ti shape memory alloy after hydrogen charging

In this work, we investigate the susceptibility of Ni–Ti superelastic wires to the strain rates during tensile testing after hydrogen charging. Cathodic hydrogen charging is performed at a current density of 10?A/m² during 2–12?h in 0.9% NaCl solution and aged for 24?h at room temperature. Specimens underwent one cycle of loading-unloading reaching a stress value of 700 MPa. During loading, strain rates from 10^?6 to 5?×?10^?2?^?s^?1 have been achieved. After 8?h of hydrogen charging, an embrittlement has been detected in the tensile strain rate range of 10^?6 to 10^?4?s^?1. In contrast, no embrittlement has been detected for strain rates of 10^?3?s^?1 and higher. However, after 12?h of hydrogen charging and 24?h of annealing at room temperature, the embrittlement occurs in the beginning of the austenite-martensite transformation for all the studied strain rate values. These results show that for a range of critical amounts of diffused hydrogen, the embrittlement of the Ni–Ti superelastic alloy strongly depends on the strain rate during the tensile test. Moreover, it has been shown that this embrittlement occurs for low values of strain rates rather than the higher ones. This behaviour is attributed to the interaction between the diffused hydrogen and growth of the martensitic domain.     

Sentiment toward marketing: Should we care about consumer alienation and readiness to use technology?

Consumer sentiment toward marketing has been extensively addressed in the marketing literature. However, while most existing studies provide contributions regarding the levels of consumer perceptions of the marketing function, most fall short of providing significant insights into the antecedents of these sentiment levels. That is to say, little is offered to help marketers understand why consumers perceive the marketing function the way they do. In this study, a conceptual framework is developed in an attempt to explore consumer sentiment toward marketing in light of the increasing technological tendencies of today's marketplace. Alienation from the marketplace is assumed to be an exogenous variable that affects the degree to which individuals are ready to embrace new technologies in everyday life. The model is empirically tested using structural equation modeling. Alienation from the marketplace is found to be negatively associated with sentiment toward marketing and the drivers of technology readiness, but positively associated with the inhibitors of technology readiness. More significantly, readiness to embrace technology is found to exhibit a strong and consistent relationship with sentiment toward marketing. Copyright © 2011 John Wiley & Sons, Ltd.     

A Note on Neat Reducts

SC, CA, QA and QEA denote the class of Pinter’s substitution algebras, Tarski’s cylindric algebras, Halmos’ quasi-polyadic and quasi-polyadic equality algebras, respectively. Let . and . We show that the class of n dimensional neat reducts of algebras in K _m is not elementary. This solves a problem in [2]. Also our result generalizes results proved in [1] and [2]. Presented by Robert Goldblatt     

On Amalgamation in Algebras of Logic

We show that not all epimorphisms are surjective in certain classes of infinite dimensional cylindric algebras, Pinter's substitution algebras and Halmos' quasipolyadic algebras with and without equality. It follows that these classes fail to have the strong amalgamation property. This answers a question in [3] and a question of Pigozzi in his landmark paper on amalgamation [9]. The cylindric case was first proved by Judit Madarasz [7]. The proof presented herein is substantially different. By a result of Németi, our result implies that the Beth-definability Theorem fails for certain expansions of first order logic     

The Idea of Public Justification in Rawls’s Law of Peoples

The article examines Rawlss Law of Peoples as an attemptto extend the conception of public justification originallydeveloped in Political Liberalism to the internationaldomain. After briefly sketching the main elements of Rawlssconception of public justification, the article examineshow this is developed in Law of Peoples, pointingout the main differences with the domestic case. The articlethen tries to show that Rawlss justificatory strategy containsa number of inconsistencies which undermine the persuasivenessof the conception of international justice he advocates. Thisin turn can be traced back to the failure fully to addressthe constituency problem facing theories ofpublic justification.

Linking actors and models for water policy development in Egypt: Analyzing actors and their options

Policy development in the field of water resources management is traditionally supported by various analysis tools and planning models. Recent years have shown increasing attention for the social dimension of policy development, as this involves different actors interacting in an attempt to satisfy their interests. This requires information on the technical and financial aspects of policy options and information on the roles and interests of different actors. The use of the analysis of options technique is explored in this article, with the aim of incorporating such information in the development of a new water policy for Egypt. His main research interest is in the use of actor analysis to support decision making in the field of water resources management, and he has worked on actor analyses for water projects in Yemen, Egypt, and The Netherlands. He received his M.Sc. in Systems Engineering, Policy Analysis and Management from Delft University of Technology in 1999. Nader El-Masry works as a water resources engineer for the National Water Resources Pan Project at the Ministry of Water resources and Irrigation in Egypt. In this position, he is involved in the development of a national water resources plan that should match Egypt’s water demands and supplies until the year 2017. He holds an M.Sc. in Water Resources and Environmental Management, from IHE, Delft, The Netherlands. Tarek Sadek has 12 years of experience in the field of hydrogeology, hydraulics, geomorphology, water resources management and environmental science. Currently, he is director of the National Water Resources Plan Project at the Ministry of Water Resources and Irrigation in Egypt. He holds a B.Sc. in Civil Engineering from the Faculty of Engineering of Cairo University (1988), an M.Sc. in Hydrology from the Department of Engineering Hydrology, University College Galway (UCG, 1992), Republic of Ireland, and a Ph.D. in Environmental Engineering from the Department of Civil & Environmental Engineering, The University of Melbourne, Australia (1997).
