Geologic Setting and Activity of Faults in the San Fernando Area, California

The faulting associated with the San Fernando earthquake of February 9, 1971, occurred in the Transverse Ranges structural province, a region noted for its strong and relatively young tectonic deformation. This is, however, the first example of historic surface faulting within the interior of that province

Heat exchange mediated by a quantum system

We consider heat transfer between two thermal reservoirs mediated by a quantum system using the generalized quantum Langevin equation. The thermal reservoirs are treated as ensembles of oscillators within the framework of the Drude-Ullersma model. General expressions for the heat current and thermal conductance are obtained for arbitrary coupling strength between the reservoirs and the mediator and for different temperature regimes. As an application of these results we discuss the origin of Fourier's law in a chain of large, but finite subsystems coupled to each other by the quantum mediators. We also address a question of anomalously large heat current between the STM tip and substrate found in a recent experiment. The question of minimum thermal conductivity is revisited in the framework of scaling theory as a potential application of the developed approach.Comment: 16 pages, 6 figure

Fissile and Non-Fissile Material Detection using Nuclear Acoustic Resonance Signatures

This report reviews progress made on NA22 project LL251DP to develop a novel technique, Nuclear Acoustic Resonance (NAR), for remote, non-destructive, nonradiation-based detection of materials of interest to Nonproliferation Programs, including {sup 235}U and {sup 239}Pu. We have met all milestones and deliverables for FY05, as shown in Table 1. In short, we have developed a magnetic shield chamber and magnetic field, develop a digital lock-in amplifier computer to integrate both the ultrasound radiation with the detector, developed strain measurements, and begin to perform initial measurements to obtain a NAR signal from aluminum at room temperature and near the earth's magnetic field. The results obtained in FY05 further support the feasibility of successful demonstration of an NAR experiment for remote, non-destructive, non-radiation-based detection of materials of interest to Nonproliferation Programs

Fissile and Non-Fissile Material Detection using Nuclear Acoustic Resonance Signatures: Final Report

This is final report on NA-22 project LL251DP, where the goal was to develop a novel technique, Nuclear Acoustic Resonance (NAR), for remote, non-destructive, nonradiation-based detection of materials of interest to Nonproliferation Programs, including {sup 235}U and {sup 239}Pu. In short, we have developed a magnetic shield chamber and magnetic field, develop a digital lock-in amplifier computer to integrate both the ultrasound radiation with the detector, developed strain measurements, and begun to perform initial measurements to obtain a NAR signal from aluminum at room temperature and near the earth's magnetic field. Since our funding was cut in FY06, I will discuss where this project can go in the future with this technology

Declared non-essential during the COVID-19 pandemic: Effects on professional identity

This study applies a social identity lens to show that, during the COVID-19 pandemic, the Dutch government’s classification of occupations and labor market sectors as essential versus non-essential imposed a professional identity threat to those categorized as non-essential. Specifically, we hypothesized (1) that non-essential workers in the Netherlands would report lower professional identification (PI) during the pandemic relative to essential workers; (2) that non-essential workers’ mandatory shift to working from home and working fewer hours would (partially) explain their lower PI relative to essential workers; (3) that gender differences would emerge in the impact of categorization as (non-)essential worker on PI levels; and (4) that lower PI would negatively relate to work productivity and performance during the pandemic. Empirical evidence based on three cross-sectional datasets sampled among the Dutch working population during two peak waves of COVID-19 infections and national lockdowns (May/June 2020; Study 1: N = 371; November/December 2020, Study 2: N = 467; Study 3 = 735) all confirmed that non-essential workers reported lower PI relative to essential workers. The explanation for this outcome varied at different stages in the pandemic. Study 1 results showed that lower PI among those declared non-essential was partially explained by non-essential workers’ work location (home-bound) and reduced work hours, but only during the 1st peak wave. As the pandemic continued (2nd peak wave; Study 2 and 3), gender differences emerged, with more negative consequences of being classified non-essential for women than men. Non-essential workers’ lower PI levels were also associated with lower work productivity and performance. These findings underscore the importance of understanding social identity processes during the pandemic. We discuss socio-psychological ramifications of government regulations to control health crises, given how these may inadvertently undermine the professional identity of over half a working population in society

Research Chimpanzees May Get a Break

A recent report by the Institute of Medicine leaves few urgent reasons standing for the continued use of chimpanzees in biomedical research. It is high time to think about their retirement, Frans de Waal argues, without neglecting prospects for non-invasive research on behavior, cognition, and genetics

The Relationships among Trait Anxiety, State Anxiety and the Goal Performance of Penalty Shoot-Out by University Soccer Players

The present study examined how the level of trait anxiety, which is a personality characteristic, influences state anxiety and penalty shoot-out performance under pressure by instruction. The high and low trait anxiety groups were selected by using Spielberger's Trait Anxiety Scale, with trait anxiety scores, and control and pressure conditions manipulated by instructions. The participants were two groups of eight university male soccer players. They individually performed 20 shots from the penalty shoot-out point, aiming at the top right and top left corner areas in the soccer goal. Each condition had 10 trials in a within-subject design. The dependent measures comprised the number of successful goals and the state anxiety scores under each instructional condition. The result showed a significant main effect of instruction. State anxiety scores increased more and the number of successful goals decreased more in high trait anxiety groups than in low trait anxiety groups under pressure instructional condition. These findings suggest that players with higher trait anxiety scores tend to experience increased state anxiety under a pressure-laden condition, and higher state anxiety interferes with goal performance

Conceptualizing national family policies: A capabilities approach

Comparative family policy research has advanced significantly in recent years. The growing availability of more and better data have improved our understanding of cross-national similarities and differences in family policies, as well as how they shape the lives of different families. Despite these advancements, comparative family policy research continues to face difficulties. The multifaceted nature of family policies makes cross-country comparisons complex. Conceptualizing our theoretical understanding of which policy aspects matter and why as well as operationalizing them into measurable indicators, often remains problematic for comparative analyses. Using examples of British and Swedish policies on childcare, a policy area particularly prone to conceptual challenges, we discuss the difficulties involved in conceptualizing family policies in comparative research. We argue that taking a capabilities approach provides a useful way forward in the field and show how such a conceptual framework allows us to more meaningfully analyze both work-family policies and their outcomes

Hakim Revisited: Preference, Choice and the Postfeminist Gender Regime

Abstract We revisit Hakim’s influential preference theory to demonstrate how it is both reflective of postfeminism and generative of its values and practices. We differentiate between two interpretations of postfeminism – first a surface level “successful but obsolete” version articulated by Hakim and a second, multi-layered account of postfeminism as a discursive formation connected to a set of discourses around gender, feminism and femininity. Drawing on this latter version we make visible the embeddedness of postfeminism in preference theory highlighting its connection to the creation of a new postfeminist subjectivity based on an agentic and ‘choosing’ femininity. We show how a consideration of preference theory in terms of the emergence and constitution of “the female chooser”, opens up aspects of Hakim’s thesis which to date have been overlooked. In addition, our postfeminist reading of preference theory draws out aspects of Hakim’s account which she herself understated. Specifically, within a contemporary context where equivalent priority is afforded to wage-work and care work, it is Hakim’s ‘adaptive’ woman who exemplifies the new postfeminist subject required to perform well simultaneously in both the work and domestic domains
