Union Maids: Unions and the Female Workforce

How have women fared in unions in recent years? The major findings of this paper are that unions have been more beneficial for women in the public sector than in the private sector, and that unionism for women is primarily a public sector wriite collar phenomenon distinguished from that of males. According to our analysis:(1) Women have come to be an increasingly large proportion of the unionized work force, and are critical in the one area in which unions have recently succeeded --the public sector.(2) In the public sector and in white collar occupations where women unionists are concentrated, unions raise women's wages more than they raise the wages of men.(3) In the private sector unions have essentially the same effect on women in wages, turnover, employment and so forth, and do not deter affirmative action programs to raise female employment. (4) Comparable worth presents a rare confluence of interests of unions in search of members, particularly in the public sector,and women in search of higher wages, and will likely continue to be used by both especially within the confines of collective bargaining.

Molecular basis of gap junctional communication in the CNS of the leech Hirudo medicinalis

Gap junctions are intercellular channels that allow the passage of ions and small molecules between cells. In the nervous system, gap junctions mediate electrical coupling between neurons. Despite sharing a common topology and similar physiology, two unrelated gap junction protein families exist in the animal kingdom. Vertebrate gap junctions are formed by members of the connexin family, whereas invertebrate gap junctions are composed of innexin proteins. Here we report the cloning of two innexins from the leech Hirudo medicinalis. These innexins show a differential expression in the leech CNS: Hm-inx1 is expressed by every neuron in the CNS but not in glia, whereas Hm-inx2 is expressed in glia but not neurons. Heterologous expression in the paired Xenopus oocyte system demonstrated that both innexins are able to form functional homotypic gap junctions. Hm-inx1 forms channels that are not strongly gated. In contrast, Hm-inx2 forms channels that are highly voltage-dependent; these channels demonstrate properties resembling those of a double rectifier. In addition, Hm-inx1 and Hm-inx2 are able to cooperate to form heterotypic gap junctions in Xenopus oocytes. The behavior of these channels is primarily that predicted from the properties of the constituent hemichannels but also demonstrates evidence of an interaction between the two. This work represents the first demonstration of a functional gap junction protein from a Lophotrochozoan animal and supports the hypothesis that connexin-based communication is restricted to the deuterostome clade

Familiars: representing Facebook users’ social behaviour through a reflective playful experience

In this paper, we describe the design and development of a social game called Familiars. Inspired by the daemons in Pullman’s “Dark Material” trilogy, Familiars are animal companions that sit on your Facebook profile and change into different animal forms based on your social activity within the social network of Facebook. . Familiars takes advantage of the powerful capabilities of the developers platform of Facebook to build a multi-dimensional picture of a player’s state based on social activity, facial expression analysis on photographs and suggestions from friends. This rich information is then distilled and presented to the player in the form of animal that the familiar chooses to take. We show how the types of animals and personalities were associated in a cross-cultural user study, and present quantitative results from the social behaviours of the players within the game in addition to qualitative data gathered from questionnaire responses

A Case of Political Philanthropy: The Rowntree Family and the Campaign for Democratic Reform

This article examines the attitude of the Rowntree family - and in particular its three prominent members, Joseph, Arnold and Seebohm Rowntree - to campaigns for democratic and constitutional reform in the later nineteenth and early twentieth centuries. It explores their views on women\u27s suffrage, reform of the House of Lords and proportional representation, and their practical involvement in the promotion or otherwise of democracy in their dealings with the press, their model community at New Earswick and in the adult education institutions with which they were associated. The article argues that, in common with many other Quakers, the Rowntrees\u27 commitment to practical philanthropy outweighed their interest in political reform, and that their commitment to the latter was, in practice, equivocal

Focus Point Supersymmetry Redux

Recent results from Higgs boson and supersymmetry searches at the Large Hadron Collider provide strong new motivations for supersymmetric theories with heavy superpartners. We reconsider focus point supersymmetry (FP SUSY), in which all squarks and sleptons may have multi-TeV masses without introducing fine-tuning in the weak scale with respect to variations in the fundamental SUSY-breaking parameters. We examine both FP SUSY and its familiar special case, the FP region of mSUGRA/CMSSM, and show that they are beautifully consistent with all particle, astroparticle, and cosmological data, including Higgs boson mass limits, null results from SUSY searches, electric dipole moments, b -> s gamma, B_s -> mu^+ mu^-, the thermal relic density of neutralinos, and dark matter searches. The observed deviation of the muon's anomalous magnetic moment from its standard model value may also be explained in FP SUSY, although not in the FP region of mSUGRA/CMSSM. In light of recent data, we advocate refined searches for FP SUSY and related scenarios with heavy squarks and sleptons, and we present a simplified parameter space to aid such analyses.Comment: v3: 20 pages, 20 figures, minor numerical error in relic density calculation corrected, fixed contours in figure

Robust Logic Gates and Realistic Quantum Computation

The composite rotation approach has been used to develop a range of robust quantum logic gates, including single qubit gates and two qubit gates, which are resistant to systematic errors in their implementation. Single qubit gates based on the BB1 family of composite rotations have been experimentally demonstrated in a variety of systems, but little study has been made of their application in extended computations, and there has been no experimental study of the corresponding robust two qubit gates to date. Here we describe an application of robust gates to Nuclear Magnetic Resonance (NMR) studies of approximate quantum counting. We find that the BB1 family of robust gates is indeed useful, but that the related NB1, PB1, B4 and P4 families of tailored logic gates are less useful than initially expected.Comment: 6 pages RevTex4 including 5 figures (3 low quality to save space).

Hand in Motion Reveals Mind in Motion

Recently, researchers have measured hand movements en route to choices on a screen to understand the dynamics of a broad range of psychological processes. We review this growing body of research and explain how manual action exposes the real-time unfolding of underlying cognitive processing. We describe how simple hand motions may be used to continuously index participants’ tentative commitments to different choice alternatives during the evolution of a behavioral response. As such, hand-tracking can provide unusually high-fidelity, real-time motor traces of the mind. These motor traces cast novel theoretical and empirical light onto a wide range of phenomena and serve as a potential bridge between far-reaching areas of psychological science – from language, to high-level cognition and learning, to social cognitive processes
