The relation of job satisfaction and degree of openness about one's sexual orientation for lesbians and gay men.

Abstract: The social environment of the workplace is an important component of job satisfaction. Different groups perceive that environment in different ways. For gay men and lesbians an important factor may be how "open" they can be about their sexual orientation in the workplace. This study assesses the relation between openness about one's sexual orientation in the workplace and job satisfaction among gay men and lesbians. Results based on responses to the Job Descriptive Index from samples in Indianapolis and San Francisco indicated a strong relationship between openness and satisfaction with co-workers. In addition, individuals who were not completely "out" in the workplace were more satisfied with their pay and tended to make more than those who were "out" to both their bosses and their co-workers. Possible implications of these results regarding job satisfaction issues for lesbians and gay men are discussed.

A spiking neuromorphic design with resistive crossbar

Abstract: Neuromorphic systems recently gained increasing attention for their high computation efficiency. Many designs have been proposed and realized with traditional CMOS technology or emerging devices. In this work, we proposed a spiking neuromorphic design built on resistive crossbar structures and implemented with IBM 130nm technology. Our design adopts a rate coding scheme where pre- and post-neuron signals are represented by digitalized pulses. The weighting function of pre-neuron signals is executed on the resistive crossbar in analog format. The computing result is transferred into digitalized output spikes via an integrate-and-fire circuit (IFC) as the post-neuron. We calibrated the computation accuracy of the entire system through circuit simulations. The results demonstrated a good match to our analytic modeling. Furthermore, we implemented both feedforward and Hopfield networks by utilizing the proposed neuromorphic design. The system performance and robustness were studied through massive Monte-Carlo simulations based on the application of digital image recognition. Comparing to the previous crossbar-based computing engine that represents data with voltage amplitude, our design can achieve >50% energy savings, while the average probability of failed recognition increase only 1.46% and 5.99% in the feedforward and Hopfield implementations, respectively.

Analysis of quantitative trait locus effects on the size and shape of mandibular molars in mice.

Abstract: While >50 genes have been found to influence the development of teeth in mice, we still know very little about the genetic basis for the adaptive characteristics of teeth, such as size and shape. We applied interval mapping procedures to Procrustes size and shape data obtained from 10 morphological landmarks on the mandibular molar row of the F(2) progeny from a cross between the LG/J and SM/J strains of mice. This revealed many more QTL for molar shape (18) than for molar centroid size (3), although levels of dominance effects were comparable among QTL for size and shape. Comparisons of patterns of Procrustes additive and dominance shape effects and ordination of QTL effects by principal components analysis suggested that the effects of the shape QTL were dispersed among the three molars and thus that none of these molars represents a genetically distinct developmental structure. The results of an analysis of co-occurrence of QTL for molar shape, mandible shape, and cranial dimensions in these mice suggested that many of the QTL for molar shape may be the same as those affecting these other sets of characters, although in some cases this could be due to effects of closely linked genes.

“Not Just For Bikers Anymore”: Popular Representations of American Tattooing

Abstract: Aux Etats-Unis, la pratique du tatouage etait autrefois un signe distinctif des marins, des criminels ou des motards et, d'une maniere generale, des couches defavorisees. Aujourd'hui, cette pratique s'est repandue au sein de populations au statut socio-culturel plus eleve et est souvent revendiquee comme une forme d'art legitime. En etudiant le traitement du sujet par les medias, l'approche des sciences humaines et le discours tenu par les adeptes du tatouage et des ornements corporels eux-memes, l'A. s'interroge sur la representativite de ces « nouveaux tatoues » . Il met en evidence l'emergence d'une nouvelle imagerie basee sur la fiction d'un passe mythique, primitif et tribal . Il pose la question de savoir si le caractere naguere subversif de ces pratiques a ete neutralise par leur banalisation, et si cette diffusion temoigne d'une evolution des valeurs sociales concernant le corps

Making culturally responsive mathematics teaching explicit: a lesson analysis tool

Abstract: In the United States, there is a need for pedagogical tools that help teachers develop essential pedagogical content knowledge and practices to meet the mathematical education needs of a growing culturally and linguistically diverse student population. In this article, we introduce an innovative lesson analysis tool that focuses on integrating mathematical thinking, language, culture, and social justice. We argue that these are essential components to culturally responsive mathematics teaching. Using data collected from a 3-year professional development initiative focused on culturally responsive mathematics teaching including teacher discussions, lesson artefacts, and interviews, the study yields two main results about the tool and its impact on teacher thinking: (1) the tool enabled teachers to systematically analyse and critique mathematics lessons with multiple dimensions including mathematical thinking, language, culture, and social justice; (2) the tool fostered purposeful pedagogical dialogue to im...
