A Racial Impact Analysis of HB 462

The adoption of House Bill 462 into law brings forth questions about the probable impact on the physical, mental, emotional and financial well-being of the women in Virginia. In particular, analysis of its effect on the minority and underserved female population is required. Understanding the origin of this new legislation and the thinking behind its proposal and subsequent adoption dictates an endeavor into the backgrounds and intended goals of its sponsors and supporters. Proponents of HB 462 were unresponsive to requests for an interview to expound on their perspective about the importance of the legislation. This precipitated the use of media clips from televised political discussions and newspaper articles to acquire direct quotes in an effort to gain insight into their position. Legislation of morality emerged as the key them from the research materials assembled. This belief is shared by many who oppose the law. The Supreme Court put forth the following as the reasoning behind its decision, in Planned Parenthood v. Casey: “Some of us as individuals find abortion offensive to our most basic principles of morality, but that cannot control our decision. Our obligation is to define the liberty of all, not to mandate our own moral code...at the heart of liberty is the right to define one\u27s own concept of existence, of meaning, of the universe, and of the mystery of human life.” Opponents of HB 462 regard the law as contrary to the decision. If, in fact, this legislation is not intended to impose the morality of its sponsors on all Virginians, as the research suggests, it is probable that it will have a disparate impact on the minority and underserved segment of the population

Monte Carlo simulation of size-effects on thermal conductivity in a 2-dimensional Ising system

A model based on microcanonical Monte Carlo method is used to study the application of the temperature gradient along a two-dimensional (2D) Ising system. We estimate the system size effects on thermal conductivity, $K$, for a nano-scale Ising layer with variable size. It is shown that $K$ scales with size as $K=cL^\alpha$ where $\alpha$ varies with temperature. Both the Metropolis and Cruetz algorithms have been used to establish the temperature gradient. Further results show that the average demon energy in the presence of an external magnetic field is zero for low temperatures.Comment: 10 pages, 7 figures, to appear in Physica

The Impact of Heavy Load Carrying on Musculoskeletal Pain and Disability Among Women in Shinyanga Region, Tanzania.

BackgroundHeavy load carrying has been associated with musculoskeletal discomfort (MSD) and disability. However, there is a lack of research investigating this association in resource-constrained settings where heavy load carrying by women is common.ObjectivesWe assessed the impact of heavy load carrying on musculoskeletal pain and disability among women in Shinyanga Region, Tanzania, in an exploratory cross-sectional study.MethodsEligible participants were a convenience sample of women, at least 18 years of age, who passed a study recruitment site carrying a load. We collected information on load-carrying practices, including frequency and time spent carrying water, wood, agricultural products, coal, sand, or rocks, and measured the weight of the load carried at the time. Outcomes included self-reported MSDs, defined as experiencing pain lasting >3 days in the neck, head, back, knees, feet and/or ankles within the last 1 year, and related disability. Using multivariable logistic regression we assessed for associations between load carrying exposures and MSDs and disability.FindingsResults showed a high prevalence of MSDs across the body regions assessed and evidence to suggest a relationship of back pain and related disability with several measures of load-carrying, including duration, frequency, and weight. Multivariable analyses revealed associations of increased load carrying exposures with low back pain (LBP) and related disability, including statistically significant increases in odds of LBP with increasing weight, total duration of load carrying/week and cumulative loads/week.ConclusionsFindings indicate a substantial burden of MSDs and disability in this population of women who carry heavy loads daily. The extent of discomfort and disability increased with increasing exposure to various load-carrying measures, especially for LBP. Larger epidemiologic studies that definitively assess relationships of load carrying with MSDs and disability are warranted

Finite Temperature and Dynamical Properties of the Random Transverse-Field Ising Spin Chain

We study numerically the paramagnetic phase of the spin-1/2 random transverse-field Ising chain, using a mapping to non-interacting fermions. We extend our earlier work, Phys. Rev. 53, 8486 (1996), to finite temperatures and to dynamical properties. Our results are consistent with the idea that there are ``Griffiths-McCoy'' singularities in the paramagnetic phase described by a continuously varying exponent $z(\delta)$, where $\delta$ measures the deviation from criticality. There are some discrepancies between the values of $z(\delta)$ obtained from different quantities, but this may be due to corrections to scaling. The average on-site time dependent correlation function decays with a power law in the paramagnetic phase, namely $\tau^{-1/z(\delta)}$, where $\tau$ is imaginary time. However, the typical value decays with a stretched exponential behavior, $\exp(-c\tau^{1/\mu})$, where $\mu$ may be related to $z(\delta)$. We also obtain results for the full probability distribution of time dependent correlation functions at different points in the paramagnetic phase.Comment: 10 pages, 14 postscript files included. The discussion of the typical time dependent correlation function has been greatly expanded. Other papers of APY are available on-line at http://schubert.ucsc.edu/pete

Critical points and quenched disorder: From Harris criterion to rare regions and smearing

We consider the influence of quenched spatial disorder on phase transitions in classical and quantum systems. We show that rare strong disorder fluctuations can have dramatic effects on critical points. In classical systems with sufficiently correlated disorder or in quantum systems with overdamped dynamics they can completely destroy the sharp phase transition by smearing. This is caused by effects similar to but stronger than Griffiths phenomena: True static order can develop on a rare region while the bulk system is still in the disordered phase. We discuss the thermodynamic behavior in the vicinity of such a smeared transition using optimal fluctuation theory, and we present numerical results for a two-dimensional model system.Comment: 10 pages, 5 eps figures, contribution to the Festschrift for Michael Schreiber's 50th birthday, final version as publishe

A qualitative study exploring the factors influencing admission to hospital from the emergency department

Objective: The number of emergency admissions to hospital in England and Wales has risen sharply in recent years and is a matter of concern to clinicians, policy makers and patients alike. However, the factors that influence this decision are poorly understood. We aimed to ascertain how non-clinical factors can affect hospital admission rates. Method: We conducted semistructured interviews with 21 participants from three acute hospital trusts. Participants included 11 emergency department (ED) doctors, 3 ED nurses, 3 managers and 4 inpatient doctors. A range of seniority was represented among these roles. Interview questions were developed from key themes identified in a theoretical framework developed by the authors to explain admission decision-making. Interviews were recorded, transcribed and analysed by two independent researchers using framework analysis. Findings: Departmental factors such as busyness, time of day and levels of senior support were identified as non-clinical influences on a decision to admit rather than discharge patients. The 4-hour waiting time target, while overall seen as positive, was described as influencing decisions around patient admission, independent of clinical need. Factors external to the hospital such as a patient’s social support and community follow-up were universally considered powerful influences on admission. Lastly, the culture within the ED was described as having a strong influence (either negatively or positively) on the decision to admit patients. Conclusion: Multiple factors were identified which go some way to explaining marked variation in admission rates observed between different EDs. Many of these factors require further inquiry through quantitative research in order to understand their influence further

Crustacea of the Cayman Islands, British West Indies. I. Records of Mysids from Shallow Water Non-Reef Habitats

A single species of mysid Siriella chierchiae has been previously reported from the Cayman Islands. However, between May 1995 and August 1999, 20 species of mysids were collected from shallow water non-reef habitats surrounding Grand Cayman and Little Cayman Islands. Of the species collected, one species Anchialina typica has a cosmopolitan distribution in tropical and subtropical seas. Thirteen species (Amathimysis cherados, A. gibba, Bowmaniella johnsoni, Dioptromysis paucispinosa, Heteromysis bermudensis, H. mayana, Mysidium columbiae, M. gracile, M. integrum, Mysidopsis bispinulata, M. brattstromi, Parvimysis bahamensis, Siriella chierchiae) are found widely distributed throughout the subtropical and tropical waters of the Northwest Atlantic. Four species (Heteromysis coralina, Mysidopsis mathewsoni, Siriella chessi, S. macrophthalma) previously known only from their type localities are reported, and two undescribed species of Heteromysis, one from Little Cayman Island, and one from Grand Cayman Island, are recognized

Integrating Financial Therapy within Family-Owned Businesses: A Theoretical Case Vignette with Recommended Strategies for Consulting with Copreneurs

Broadly speaking, finances are often one of the most strenuous aspects of a relationship. One potential contributing factor to financial conflict experienced by couples are having different beliefs or attitudes towards money, coined previously as money scripts (Klontz, Kahler, & Klontz, 2008). Differing money scripts between partners can cause a breach in understanding of their partner\u27s internal experience around money that may lead to misunderstanding and conflict. This may be magnified for copreneurs, or romantic partners, who integrate a personal and working relationship within a business’s ownership structure. In this unique arrangement of personal and professional relationships, the traditional lines separating work and home life are either nonexistent or blurred. This paper serves to explore the conflict through a hypothetical case study and provides detailed financial therapy interventions that may be used to help copreneurs who are experiencing money conflict. The outline of interventions serves to aid financial therapists in their work with clients who are part of a family-owned business by helping these clients better communicate through the unique dynamics of a copreneur relationship

Dynamic Scaling in Diluted Systems Phase Transitions: Deactivation trough Thermal Dilution

Activated scaling is confirmed to hold in transverse field induced phase transitions of randomly diluted Ising systems. Quantum Monte Carlo calculations have been made not just at the percolation threshold but well bellow and above it including the Griffiths-McCoy phase. A novel deactivation phenomena in the Griffiths-McCoy phase is observed using a thermal (in contrast to random) dilution of the system.Comment: 4 pages, 4 figures, RevTe
