Confrontation Confronted

The following article is an edited version of the amicus curiae brief filed with the Supreme Court of the United States in the October Term, 1998, in the case of Benjamin Lee Lilly v. Commonwealth of Virginia(No.98-5881). This case raises important questions about the confrontation clause, which has been a vital ingredient of the fair trial right for hundreds of years, Professor Richard Friedman and his co-authors say. In particular, this case presents the Court with an opportunity to reconsider the relationship between the confrontation clause and the law of hearsay. On June 10 the Court handed down a decision in favor of Lilly. Justice Stephen Breyer, a member of the plurality, wrote a concurring opinion citing this brief favorably and suggested that a future case might call for the Court to adopt its approach

Algorithms for Highly Symmetric Linear and Integer Programs

This paper deals with exploiting symmetry for solving linear and integer programming problems. Basic properties of linear representations of finite groups can be used to reduce symmetric linear programming to solving linear programs of lower dimension. Combining this approach with knowledge of the geometry of feasible integer solutions yields an algorithm for solving highly symmetric integer linear programs which only takes time which is linear in the number of constraints and quadratic in the dimension.Comment: 21 pages, 1 figure; some references and further comments added, title slightly change

“An Institution Can Have Good Intentions and Still Be Atrocious : Transgender and Gender Expansive Experiences in Social Work Education

Educational settings have been found to be challenging arenas for transgender and gender expansive (TGE) youth and young adults due to misgendering, lack of affirming bathrooms, systemic exclusion (e.g., legal names and lack of inclusive gender identity demographic options), and frequent silence or avoidance related to TGE issues. Though studies of TGE adult experiences in higher education are emerging, most explore disaffirming experiences. Social work education focuses on diversity, equity, and inclusion, along with how to promote social justice, which suggests more affirming environments for TGE individuals. However, little is known about the experiences of TGE students and even less about faculty in social work education. To help fill this gap, the researchers interviewed 23 TGE social work students and faculty to explore their experiences of gender-related affirmation and challenges in social work educational programs. The findings from a thematic analysis identified examples of affirming and disaffirming experiences and recommendations for improving gender affirmation and inclusion in social work programs. Social work is in a strategic position to serve the needs and impact the social welfare of TGE individuals, starting with educational settings

Time Correlation Functions of Three Classical Heisenberg Spins on an Isosceles Triangle and on a Chain: Strong Effects of Broken Symmetry

At arbitrary temperature $T$, we solve for the dynamics of single molecule magnets composed of three classical Heisenberg spins either on a chain with two equal exchange constants $J_1$, or on an isosceles triangle with a third, different exchange constant $J_2$. As T\rightrarrow\infty, the Fourier transforms and long-time asymptotic behaviors of the two-spin time correlation functions are evaluated exactly. The lack of translational symmetry on a chain or an isosceles triangle yields time correlation functions that differ strikingly from those on an equilateral trinagle with $J_1=J_2$. At low $T$, the Fourier transforms of the two autocorrelation functions with $J_1\ne J_2$ show one and four modes, respectively. For a semi-infinite $J_2/J_1$ range, one mode is a central peak. At the origin of this range, this mode has a novel scaling form.Comment: 9 pages, 14 figures, accepted for publication in Phys. Rev.

Inter-group alliance dynamics in Indo-Pacific bottlenose dolphins (Tursiops aduncus)

The social intelligence hypothesis holds that complex social relationships are the major selective force underlying the evolution of large brain size and intelligence. Complex social relationships are exemplified by coalitions and alliances that are mediated by affiliative behavior, resulting in differentiated but shifting relationships. Male Indo-Pacific bottlenose dolphins in Shark Bay, Australia, form three alliance levels or ‘orders’, primarily among non-relatives. Strategic alliance formation has been documented within both first- and second-order alliances and between second-order alliances (‘third-order alliances’), revealing that the formation of strategic inter-group alliances is not limited to humans. Here we conducted a fine-scale study on 22 adult males over a 6-year period to determine if third-order alliance relationships are differentiated, and mediated by affiliative interactions. We found third-order alliance relationships were strongly differentiated, with key individuals playing a disproportionate role in maintaining alliances. Nonetheless, affiliative interactions occurred broadly between third-order allies, indicating males maintain bonds with third-order allies of varying strength. We also documented a shift in relationships and formation of a new third-order alliance. These findings further our understanding of dolphin alliance dynamics and provide evidence that strategic alliance formation is found in all three alliance levels, a phenomenon with no peer among non-human animals

The tip-link antigen, a protein associated with the transduction complex of sensory hair cells, is protocadherin-15

Sound and acceleration are detected by hair bundles, mechanosensory structures located at the apical pole of hair cells in the inner ear. The different elements of the hair bundle, the stereocilia and a kinocilium, are interconnected by a variety of link types. One of these links, the tip link, connects the top of a shorter stereocilium with the lateral membrane of an adjacent taller stereocilium and may gate the mechanotransducer channel of the hair cell. Mass spectrometric and Western blot analyses identify the tip-link antigen, a hitherto unidentified antigen specifically associated with the tip and kinocilial links of sensory hair bundles in the inner ear and the ciliary calyx of photoreceptors in the eye, as an avian ortholog of human protocadherin-15, a product of the gene for the deaf/blindness Usher syndrome type 1F/DFNB23 locus. Multiple protocadherin-15 transcripts are shown to be expressed in the mouse inner ear, and these define four major isoform classes, two with entirely novel, previously unidentified cytoplasmic domains. Antibodies to the three cytoplasmic domain-containing isoform classes reveal that each has a different spatiotemporal expression pattern in the developing and mature inner ear. Two isoforms are distributed in a manner compatible for association with the tip-link complex. An isoform located at the tips of stereocilia is sensitive to calcium chelation and proteolysis with subtilisin and reappears at the tips of stereocilia as transduction recovers after the removal of calcium chelators. Protocadherin-15 is therefore associated with the tip-link complex and may be an integral component of this structure and/or required for its formatio

Posttraumatic Stress among Young Urban Children Exposed to Family Violence and Other Potentially Traumatic Events

This study examines the relationship between the number of types of traumatic events experienced by children 3 to 6 years old, parenting stress, and children\u27s posttraumatic stress (PTS). Parents and caregivers provided data for 154 urban children admitted into community-based mental health or developmental services. By parent and caregiver report, children experienced an average of 4.9 different types of potentially traumatic events. Nearly one quarter of the children evidenced clinically significant PTS. Posttraumatic stress was positively and significantly related to family violence and other family-related trauma exposure, nonfamily violence and trauma exposure, and parenting stress. Additionally, parenting stress partially mediated the relationship between family violence and trauma exposure and PTS. This study highlights the need for early violence and trauma exposure screening in help-seeking populations so that appropriate interventions are initiated

Science and Ideology in Economic, Political, and Social Thought

This paper has two sources: One is my own research in three broad areas: business cycles, economic measurement and social choice. In all of these fields I attempted to apply the basic precepts of the scientific method as it is understood in the natural sciences. I found that my effort at using natural science methods in economics was met with little understanding and often considerable hostility. I found economics to be driven less by common sense and empirical evidence, then by various ideologies that exhibited either a political or a methodological bias, or both. This brings me to the second source: Several books have appeared recently that describe in historical terms the ideological forces that have shaped either the direct areas in which I worked, or a broader background. These books taught me that the ideological forces in the social sciences are even stronger than I imagined on the basis of my own experiences. The scientific method is the antipode to ideology. I feel that the scientific work that I have done on specific, long standing and fundamental problems in economics and political science have given me additional insights into the destructive role of ideology beyond the history of thought orientation of the works I will be discussing
