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.
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
Investigating the Early Stages of Person Perception: The Asymmetry of Social Categorization by Sex vs. Age
The wealth of information provided by facial cues presents challenges to our understanding of these early stages of person perception. The current study aimed to uncover the dynamics of processing multiply categorizable faces, notably as a function of their gender and age. Using a modified four-choice version of a mouse-tracking paradigm (which assesses the relative dominance of two categorical dimensions), the relative influence that sex and age have on each other during categorization of infant, younger adult, and older adult faces was investigated. Results of these experiments demonstrate that when sex and age dimensions are simultaneously categorized, only for infant faces does age influence sex categorization. In contrast, the sex of both young and older adults was shown to influence age categorization. The functional implications of these findings are discussed in light of previous person perception research

A Cross-Media Presence Questionnaire: The ITC-Sense of Presence Inventory
The presence research community would benefit from a reliable and valid cross-media presence measure that allows results from different laboratories to be compared and a more comprehensive knowledge base to be developed. The ITC-Sense of Presence Inventory (ITC-SOPI) is a new state questionnaire measure whose development has been informed by previous research on the determinants of presence and current self-report measures. It focuses on users' experiences of media, with no reference to objective system parameters. More than 600 people completed the ITC-SOPI following an experience with one of a range of noninteractive and interactive media. Exploratory analysis (principal axis factoring) revealed four factors: Sense of Physical Space, Engagement, Ecological Validity, and Negative Effects. Relations between the factors and the consistency of the factor structure with others reported in the literature are discussed. Preliminary analyses described here demonstrate that the ITC-SOPI is reliable and valid, but more rigorous testing of its psychometric properties and applicability to interactive virtual environments is required. Subject to satisfactory confirmatory analyses, the ITC-SOPI will offer researchers using a range of media systems a tool with which to measure four facets of a media experience that are putatively related to presence
Restricted Quantum Theory of Affine Toda Solitons
We quantise the reduced theory obtained by substituting the soliton solutions
of affine Toda theory into its symplectic form. The semi-classical S-matrix is
found to involve the classical Euler dilogarithm.Comment: 10pp, LaTe
Detrimental effects of duplicate reads and low complexity regions on RNA- and ChIP-seq data
Background Adapter trimming and removal of duplicate reads are common practices in next-generation sequencing pipelines. Sequencing reads ambiguously mapped to repetitive and low complexity regions can also be problematic for accurate assessment of the biological signal, yet their impact on sequencing data has not received much attention. We investigate how trimming the adapters, removing duplicates, and filtering out reads overlapping low complexity regions influence the significance of biological signal in RNA- and ChIP-seq experiments. Methods We assessed the effect of data processing steps on the alignment statistics and the functional enrichment analysis results of RNA- and ChIP-seq data. We compared differentially processed RNA-seq data with matching microarray data on the same patient samples to determine whether changes in pre-processing improved correlation between the two. We have developed a simple tool to remove low complexity regions, RepeatSoaker, available at https://github.com/mdozmorov/RepeatSoaker, and tested its effect on the alignment statistics and the results of the enrichment analyses. Results Both adapter trimming and duplicate removal moderately improved the strength of biological signals in RNA-seq and ChIP-seq data. Aggressive filtering of reads overlapping with low complexity regions, as defined by RepeatMasker, further improved the strength of biological signals, and the correlation between RNA-seq and microarray gene expression data. Conclusions Adapter trimming and duplicates removal, coupled with filtering out reads overlapping low complexity regions, is shown to increase the quality and reliability of detecting biological signals in RNA-seq and ChIP-seq data
