Measuring Legislator Ideology*

Objective. Previous models of roll‐call voting have either ignored the role of legislator ideology or have employed questionable measures of it. A defensible measure of legislator ideology is needed. Methods. This study surveys former members of Congress (MCs) to obtain a new measure of legislator preferences. The measure has several attractive properties, appears to be valid, and is unique compared to a preference measure others have used. Results. Validating the measure in a model of roll‐call voting reveals that the importance of legislators' ideologies is similar to that of their party affiliations. Conclusions. A useful measure of legislators' ideologies can be generated using a postretirement instrument.     

On Bayesian nonparametric modelling of two correlated distributions

In this paper, we consider the problem of modelling a pair of related distributions using Bayesian nonparametric methods. A representation of the distributions as weighted sums of distributions is derived through normalisation. This allows us to define several classes of nonparametric priors. The properties of these distributions are explored and efficient Markov chain Monte Carlo methods are developed. The methodology is illustrated on simulated data and an example concerning hospital efficiency measurement.     

Reports of Conferences, Institutes, and Seminars

Late winter and early spring of 2009 was a busy conference time for librarians. Some of the conferences held during that time are reported herein: the American Library Association Midwinter Conference, January 23–28; Electronic Resources and Libraries (E&RL), February 9–12; the North Carolina Serials Conference, March 27; the New England Technical Services Librarians' (NETSL) Spring Conference, April 17; and the Technical, Electronic and Digital Services Interest Group (TEDSIG) Spring Meeting, April 24.     

The Middle Men: An Introduction to the Transmasculine Identities

Little attention has been paid to the transmasculine (female-to-male [FTM] transsexual and transgender) community. When we hear the word transsexual, most of us immediately think of male-to-females. However, the FTM community is thriving and rich with variety. This essay provides an inside look at the little-examined identities within the almost invisible world of FTMs. Positing that the transmasculine community does not subscribe to just one mode of identification, I illuminate the varied experiences of transmasculine individuals by organizing the plethora of defining FTM labels into three broad categories: Woodworkers, Transmen, and Genderqueers. Within the admittedly limiting confines of this taxonomy, it becomes possible to gain a better understanding of the people behind the labels and achieve insight into their individual therapeutic needs.     

Reports of Conferences,Institutes, and Seminars

A busy time for librarians was late May through early July 2008 with the Ohio Valley Group of Technical Services Librarians meeting May 14–16, the North American Serials Interest Group meeting June 5–8, and an American Library Association preconference Electronic Serials 101: What I Wished I’d Known Before I Got in Over My Head, June 27.     

Finding the majority-rule equilibrium under lexicographic comparison of candidates

This paper considers the well studied problem of the existence of an undominated point, under the assumption of lexicographic preferences of voters, as espoused by Taylor in [24]. We extend Taylor's model to situations were we allow for (i) voters to have different ranings of the issues in n-dimensional issue space and (ii) a candidate to be disregarded by a voter if his stand on any one or more of the issues involved in the election is perceived to be too extreme by the voter and (iii) combinations of (i) and (ii). We extend the results of Taylor by demonstrating the non-existence of an equilibrium point in these models in general and then showing that under special circumstances, specialized variants of the “median” point(s) represent equilibrium or undominated points in these models too. Thus a model of voting behavior results that is closer approximation of reality in that historically incumbents tend to win. The primary conclusion of the paper is to suggest that incumbents tend to have an advantage when the election process is characterized by a large presence of special interests or as information becomes more expensive to acquire.

Posttraumatic Growth in Relationally Betrayed Women

The research literature on relational betrayal in a committed relationship has focused on the resulting trauma from the betrayal; however, few studies investigated the potential for posttraumatic growth following a relational betrayal. This study investigated the presence of posttraumatic growth in relationally betrayed women. The research focused on women's perceptions of the relational betrayal, and factors that facilitated posttraumatic growth. Results indicated relationally betrayed women perceived the betrayal as a traumatic event, to the extent that some met criteria for PTSD diagnosis. The passage of time was significant corollary to posttraumatic growth when moderated by a PTSD diagnosis. Finally, certain resources were reported to be more helpful than others in the development of posttraumatic growth. Clinical implications are presented.
