Like Family: Rights of Nonmarried Cohabitational Partners in Loss of Consortium Actions

The organization of family life in American society has changed dramatically in recent decades. Changing societal morals and increases in divorce rates mean that fewer households are organized around the traditional nuclear family model. Courts have struggled to understand and classify these alternative family arrangements, and most have denied recovery in actions for loss of consortium by nontnarried cohabitants. This Note argues that changes in related areas of law and in the loss of consortium doctrine itself indicate that nonrnarried cohabitants should be allowed to recover. Specifically, jtalicial understanding of the purpose of loss of consortium recovery has shifted, and nonnaarried cohabitants have been allowed to recover in closely analogous actions such as negligent infliction of emotional distress. This Note proposes adoption of a standard similar to the one employed in negligent infliction of emotional distress actions. Such a standard provides a framework to determine whether damage to a relationship is severe enough to be compensable, while still providing adequate safeguards to prevent a wave of frivolous suits

Genealogical Society Libraries: A Treasure Trove of Family Histories

Oregon’s genealogical societies come in all shapes and sizes, and their collections and services are just as varied. Some societies operate and maintain a standalone library; others’ holdings are part of a private or public library system, or housed in alternative public or private buildings. One thing all have in common, though, is that their unique materials are made available to the general public in addition to the society’s members, enabling anyone tracing their family tree—whether writer, researcher, or casual investigator—to access their collections. Genealogical library collections may include books, periodicals, microfilm/microfiche, maps, photographs, research aids, reference books, local city directories, scrapbooks, obituaries, and even original county court record books. Manuscript collections (frequently referred to as vertical files) gather the work of earlier researchers and include items often unavailable elsewhere such as pedigree charts, family group sheets, and other original records and documents donated to the society. These files might hold a naturalization certificate, Bible record, or letter from one of YOUR ancestors

Polarized Neutron Laue Diffraction on a Crystal Containing Dynamically Polarized Proton Spins

We report on a polarized-neutron Laue diffraction experiment on a single crystal of neodynium doped lanthanum magnesium nitrate hydrate containing polarized proton spins. By using dynamic nuclear polarization to polarize the proton spins, we demonstrate that the intensities of the Bragg peaks can be enhanced or diminished significantly, whilst the incoherent background, due to proton spin disorder, is reduced. It follows that the method offers unique possibilities to tune continuously the contrast of the Bragg reflections and thereby represents a new tool for increasing substantially the signal-to-noise ratio in neutron diffraction patterns of hydrogenous matter.Comment: 5 pages, 3 figure

Cyclin-Dependent Kinase regulation and function during meiosis

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Biology, 2010.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student submitted PDF version of thesis.Includes bibliographical references.Meiosis is the process by which haploid gametes are produced from a diploid progenitor cell. Accurate completion of the meiotic divisions requires a variety of modifications to the mitotic chromosome segregation machinery, which allow the reductional meiotic chromosome segregation program to occur. Oscillations in the activity of Cyclin- Dependent Kinases (CDKs) drive virtually every event in the mitotic cell cycle, including events such as cell cycle entry, DNA replication, and chromosome segregation. While much is known about the activity of CDKs, the regulation of CDK activity, and the mechanisms by which CDK activity promotes cell cycle events during vegetative growth in Saccharomyces cerevisiae, relatively little is known about the roles of CDKs during the meiotic divisions. This work examines CDK activity during meiosis, the regulation of CDK activity during meiosis, and mechanisms by which CDKs regulate proper meiotic chromosome segregation. First, a striking diversity in Clb-CDK activity is observed during meiosis, including the identification of Clb1-CDK, and Clb3-CDK as meiosis I and meiosis II specific Clb-CDKs respectively. Second, Clb3 protein is shown to be restricted to meiosis II by translational control mediated by the 5'UTR of the CLB3 message. Finally, premature production of Clb3 results in the premature separation of sister-chromatids during meiosis I.by Thomas M. Carlile.Ph.D

A Mechanistic Modeling Framework for Predicting Metabolic Interactions in Complex Mixtures

Background: Computational modeling of the absorption, distribution, metabolism, and excretion of chemicals is now theoretically able to describe metabolic interactions in realistic mixtures of tens to hundreds of substances. That framework awaits validation

Whole-Genome Sequence Analysis of an Extensively Drug-Resistant Salmonella enterica Serovar Agona Isolate from an Australian Silver Gull (Chroicocephalus novaehollandiae) Reveals the Acquisition of Multidrug Resistance Plasmids.

Although most of the approximately 94 million annual human cases of gastroenteritis due to Salmonella enterica resolve without medical intervention, antimicrobial therapy is recommended for patients with severe disease. Wild birds can be natural hosts of Salmonella that pose a threat to human health; however, multiple-drug-resistant serovars of S. enterica have rarely been described. In 2012, silver gull (Chroicocephalus novaehollandiae) chicks at a major breeding colony were shown to host Salmonella, most isolates of which were susceptible to antibiotics. However, multiple-drug-resistant (MDR) Escherichia coli with resistance to carbapenems, ceftazidime, and fluoroquinolones was reported from this breeding colony. In this paper, we describe a novel MDR Salmonella strain subsequently isolated from the same breeding colony. SG17-135, an isolate of S. enterica with phenotypic resistance to 12 individual antibiotics but only nine antibiotic classes including penicillins, cephalosporins, monobactams, macrolides, fluoroquinolones, aminoglycosides, dihydrofolate reductase inhibitors (trimethoprim), sulfonamides, and glycylcyclines was recovered from a gull chick in 2017. Whole-genome sequence (WGS) analysis of SG17-135 identified it as Salmonella enterica serovar Agona (S Agona) with a chromosome comprising 4,813,284 bp, an IncHI2 ST2 plasmid (pSG17-135-HI2) of 311,615 bp, and an IncX1 plasmid (pSG17-135-X) of 27,511 bp. pSG17-135-HI2 housed a complex resistance region comprising 16 antimicrobial resistance genes including blaCTX-M-55 The acquisition of MDR plasmids by S. enterica described here poses a serious threat to human health. Our study highlights the importance of taking a One Health approach to identify environmental reservoirs of drug-resistant pathogens and MDR plasmids.IMPORTANCE Defining environmental reservoirs hosting mobile genetic elements that shuttle critically important antibiotic resistance genes is key to understanding antimicrobial resistance (AMR) from a One Health perspective. Gulls frequent public amenities, parklands, and sewage and other waste disposal sites and carry drug-resistant Escherichia coli Here, we report on SG17-135, a strain of Salmonella enterica serovar Agona isolated from the cloaca of a silver gull chick nesting on an island in geographic proximity to the greater metropolitan area of Sydney, Australia. SG17-135 is closely related to pathogenic strains of S Agona, displays resistance to nine antimicrobial classes, and carries important virulence gene cargo. Most of the antibiotic resistance genes hosted by SG17-135 are clustered on a large IncHI2 plasmid and are flanked by copies of IS26 Wild birds represent an important link in the evolution and transmission of resistance plasmids, and an understanding of their behavior is needed to expose the interplay between clinical and environmental microbial communities

Finding Space for Agency in Permanent Exclusion from School

This article aims to examine the experiences of pupils and professionals who are affected by permanent exclusion (what used to be called being expelled) from school. An ethnographic study conducted during the author’s employment as a Pupil Support Officer within secondary schools and the children’s services department of an urban local authority in England explores the idea that professionals may be forced to make inequitable decisions about including or excluding pupils in the face of powerful competition between the politically unchallengeable concepts of tolerance, inclusivity, attainment, and choice. The article argues that the tensions of multi-agency working are focused within what will be described as the contested space of the young person’s ‘extended body’. However, whilst the contested nature of this space renders it vulnerable to negative description and to the biased judgements of authoritarian power, it also offers itself as a space for emancipatory self description by the young person and for the expression of agency on the part of those professionals working for social justice

Relative sound localisation abilities in human listeners

Spatial acuity varies with sound-source azimuth, signal-to-noise ratio, and the spectral characteristics of the sound source. Here, the spatial localisation abilities of listeners were assessed using a relative localisation task. This task tested localisation ability at fixed angular separations throughout space using a two-alternative forced-choice design across a variety of listening conditions. Subjects were required to determine whether a target sound originated to the left or right of a preceding reference in the presence of a multi-source noise background. Experiment 1 demonstrated that subjects' ability to determine the relative location of two sources declined with less favourable signal-to-noise ratios and at peripheral locations. Experiment 2 assessed performance with both broadband and spectrally restricted stimuli designed to limit localisation cues to predominantly interaural level differences or interaural timing differences (ITDs). Predictions generated from topographic, modified topographic, and two-channel models of sound localisation suggest that for low-pass stimuli, where ITD cues were dominant, the two-channel model provides an adequate description of the experimental data, whereas for broadband and high frequency bandpass stimuli none of the models was able to fully account for performance. Experiment 3 demonstrated that relative localisation performance was uninfluenced by shifts in gaze direction
