description: We show that the wave function of a one dimensional spinor gas with contact $s$-wave interaction, either bosonic or fermionic, can be mapped to the direct product of the wave function of a spinless Fermi gas with short-range $p$-wave interaction and that of a spin system governed by spin parity projection operators. Applying this mapping to strongly interacting spinor gases, we obtain a generalized spin chain model that captures both the static and dynamics properties of the system. Using this spin chain model, we investigate the breathing mode frequency and the quench dynamics of strongly interacting harmonically trapped spinor gases.

description: At the time it celebrates one century of existence, general relativity---Einstein's theory for gravitation---is given a companion theory: the so-called teleparallel gravity, or teleparallelism for short. This new theory is fully equivalent to general relativity in what concerns physical results, but is deeply different from the conceptual point of view. Its characteristics make of teleparallel gravity an appealing theory, which provides an entirely new way to think the gravitational interaction.

Reducing Methicillin-Resistant Staphylococcus Aureus (MRSA) In the Hospital Setting
Creators: name: Woolwich, Amy, RN, BSN
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: One third of all people in America walk around with staphylococcus germs in their noses. Two and a half million people carry the strain of staphylococcus called methicillin-resistant Staphylococcus aureus (MRSA) that most antibiotics can't kill. MRSA is one of the fastest growing pathogens known today. The United States has the world's second highest rate of MRSA infections, and it continues to rise. As awareness and incidence of MRSA has increased, a call for mandatory test cultures has grown. While these tests are crucial to controlling MRSA, mandating them puts undue burden on hospitals when a well-tested series of steps has proven extremely effective in preventing the spread of the deadly bacteria. With the increase of healthcare associated MRSA infections, much of the research over the past ten years has been devoted to uncovering strategies to reduce the incidence within the healthcare setting. Studies have shown that healthcare institutions can greatly reduce the incidence of MRSA by instituting the following five components of care: I) Hand hygiene 2) Decontamination of the environment and equipment 3) Active surveillance 4) Contact precautions for infected and colonized patients 5) Central line and ventilator device bundles. Many researchers and organizations are also evaluating whether mandatory active surveillance cultures (ASCs) will reduce its incidence. Leaders in infection control organizations do not support mandating ASCs, but do support the practice as an effective way to reduce the transmission of MRS A. As infection control leaders it is imperative to recognize the differences in needs and resources within healthcare institutions throughout the United States. By mandating ASCs many healthcare institutions are obligated to utilize resources on ASCs that might be better used in education of staff and the community. Research has proven the effectiveness of the five components of care in the reduction of MRS A. However, to what extent and how these five components of care are implemented should be left up to each individual healthcare institution as to how it best fits their needs. This paper will discuss the evidence-based five components to reduce MRSA and give healthcare providers the knowledge to implement them within their individual healthcare institutions.

To do this, we associate to each genus one normal curve of degree $n$, an $n \times n$ alternating matrix of quadratic forms in $n$ variables, that represents the invariant differential. We then exhibit the invariants we need as homogeneous polynomials of degrees $4$ and $6$ in the coefficients of the entries of this matrix.

Facing the rising cost of chemotherapy in an aging population: Proposed reform of the drug approval process
Creators: name: Sanoff, Hanna K., MD
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: The emergence of new, effective therapeutic options has brought marked improvements in survival times and cure rates for many cancers. The cost of these advances, however, is staggering and has stretched thin the budget of the Centers for Medicare and Medicaid Services (CMS). In order to maintain its fiscal stability, CMS' s cost containment measures (e.g. the Medicare Modernization Act of 2003) have shifted cost to providers and health care consumers rather than restrict the availability of drugs or services. Such measures, however, fail to contain cost as they do not address the underlying etiology of soaring health care cost: unfettered access to exorbitantly priced drugs. I use the example of chemotherapy for colorectal cancer in the elderly to explore the cost of cancer care, and to demonstrate how current policies not only fail to contain cost, but also unintentionally increase the disparity between the wealthy who can afford optimal health care, and the average American senior who may be unable to afford stateof- the-art cancer care. I propose that in our system with finite resources, we must accept that we cannot provide all possible care to everyone. If cost containment measures are to be successful and equitable, we must redefine quality care as excellent care for all, rather than all care for some. Cost-effectiveness, in addition to comparative clinical effectiveness, must become a focus of the drug approval process. Reforms such as the establishment of an Effectiveness Committee to review the clinical and cost-effectiveness of all new drugs, use of these data through a new conditional FDA approval system and incorporation of cost-effectiveness in CMS's reimbursement decisions, and a cost-sharing policy with the pharmaceutical industry for drugs receiving only conditional approval by the FDA would begin to slow the growth in the cost of care. Although making cost-effectiveness a central consideration in drug approval and reimbursement decisions is likely to be unpopular, the American populace and its physicians are already quite dissatisfied with the extent to which they must shoulder the burden ofthe rising cost of medical care. Failure to act will only worsen this dissatisfaction, while allowing the growing divide between the care available to the wealthy and the care available to most Americans to widen.

description: This paper investigates the non-equilibrium hydrodynamic behavior of a simple totally asymmetric interacting particle system of particles, antiparticles and holes on $\mathbb{Z}$. Rigorous hydrodynamic results apply to our model with a hydrodynamic flux that is exactly calculated and shown to change convexity in some region of the model parameters. We then characterize the entropy solutions of the hydrodynamic equation with step initial condition in this scenario which include various mixtures of rarefaction fans and shock waves. We highlight how the phase diagram of the model changes by varying the model parameters.

Family Physicians' Attitudes Toward Inpatient Care in North Carolina: 2001
Creators: name: Maniscalco, Mary M., M.D.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2002

description: Over the past several years, the number of physicians practicing as hospitalists or using hospitalists to care for their inpatients has grown. The use of hospitalists departs from a more traditional model of practice in the U.S. in which primary care doctors care for their patients in both the inpatient and outpatient settings. Hospitalists pose a special challenge for family physicians as the majority ofhospitalists are internists or subspecialists. Historically, the discipline of family practice in part grew out of a concern for maintaining hospital privileges, a tradition potentially threatened by the growth ofhospitalists. Prior research has shown that practice setting and personal characteristics influence whether or not physicians practice inpatient medicine. This paper begins to look at whether or not attitudes toward hospital care influence whether or not physicians practice inpatient medicine. Using 2001 survey data from a random sample of practicing family physicians in North Carolina, this paper describes current self-reported practice and personal characteristics of these physicians as well as examines their attitudes toward hospital care. In 2001, 66% of family practitioners in North Carolina provide inpatient care and 11% practice obstetrics. While 16% of family practitioners work as rotating hospitalists, only 1% work as full-time hospitalists. There are differences in attitudes toward hospital care between physicians who care for hospitalized patients and those who do not. There are some smaller differences in attitudes between physicians who care for their own patients in the hospital and those who work as rotating hospitalists. The results of bivariate analysis suggest that attitudes, the practice of obstetrics, hospital size and post-graduate year less than 25 are positively associated with providing hospital care. In multivariate logistic regression models, attitudes toward hospital care, hospital size and post-graduate year less than 25 are positively associated with providing inpatient care. The results of this study, other published literature, and the growth of the use ofhospitalists have potential effects on the role family physicians play in caring for hospitalized patients. In addition, there are implications for the future training of family physicians, care of their patients, and research in the discipline.

description: In the current concordance cosmology small halos are expected to be completely dark and can significantly perturb low-mass galaxies during minor merger interactions. These interactions may well contribute to the diversity of the dwarf galaxy population. Dwarf galaxies in the field are often observed to have peculiarities in their structure, morphology, and kinematics, as well as strong bursts of star formation without apparent cause. We aim to characterize the signatures of minor mergers of dwarf galaxies with dark satellites to aid their observational identification. We explore and quantify a variety of structural, morphological, and kinematic indicators of merging dwarf galaxies and their remnants using a suite of hydrodynamical simulations. The most sensitive indicators of mergers with dark satellites are large asymmetries in the gaseous and stellar distributions, enhanced central surface brightness and starbursts, and velocity offsets and misalignments between the cold gas and stellar components. In general, merging systems span a wide range of values of the most commonly used indicators, while isolated objects tend to have more confined values. Interestingly, we find in our simulations that a significantly off-centered burst of star formation can pinpoint the location of the dark satellite. Observational systems with such characteristics are perhaps the most promising for unveiling the presence of the hitherto, missing satellites.

A Systematic Review of the Treatment of Borderline Personality Disorder using Fluoxetine and Olanzapine
Creators: name: Ruminjo, Anne Wanjiru
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: BACKGROUND: Borderline personality disorder (BPD) is prevalent among the general population (2%). Treatment of BPD is with the use of psychotherapy and pharmacotherapy. The use of psychotherapy for treatment of BPD has been well established, the effectiveness of pharmacotherapy remains less clear. OBJECTIVES: To evaluate the effectiveness of olanzapine and fluoxetine on outcomes (including depression, anxiety, anger/impulsivity/aggression and global assessment of functioning) of BPD patients. SEARCH STRATEGY: Searched PubMed for the terms fluoxetine and borderline personality disorder and olanzapine and borderline personality disorder. SELECTION CRITERIA: Only included randomized controlled trials in the English language that focused primarily on objective as stated above. MAIN RESULTS: Two fluoxetine studies included in this review, only one study showed significant improvement in depression and anger in BPD patients receiving fluoxetine but this was small (approximately 20% ). Both studies showed significant improvement in global assessment of functioning (GAF) in fluoxetine groups. Four olanzapine studies included in this review, 3 compared olanzapine to placebo and 1 compared olanzapine to a mixed olanzapine-fluoxetine combination (OFC) to fluoxetine. In 2 of the 3 olanzapine studies, there was significant improvement in depression, anxiety and GAF, improvements ranged from 21%-39% for depression and anxiety. All 3 olanzapine studies show improvement in anger/impulsivity/aggression (highest improvement was 49%). In the mixed study, OFC and olanzapine group showed significant improvement in depression and anger but this improvement was mild. Anxiety and GAF were not measured in the mixed study. CONCLUSIONS: Overall, fluoxetine leads to mild improvement in depression, anger and GAF. Olanzapine treatment of BPD patients leads to mild-moderate improvement in depression, anxiety, anger/impulsivity/aggression and GAF.

Childhood Obesity: Impact of School-based Interventions on Body Mass Index and the Role of the School Health Nurse
Creators: name: Jacobs, Joan C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Childhood obesity has become a national epidemic and has gained notoriety as a public health issue. The treatment and prevention of childhood obesity has become a health priority due to the impact of obesity on acute and chronic disease, general health, development and overall well-being of children. The school environment is an ideal setting for implementation of obesity prevention programs where children and adolescents can learn healthy eating and engage in physical activity. However, many school-based programs have been found to have minimal or no impact on the adiposity of children. This paper examines the literature of school-based obesity prevention programs and the role that the school nurse has in the implementation of these school-based programs. There is an abundance of programs designed to decrease or prevent weight gain in children and adolescents. These include: (a) cardiovascular disease prevention programs that target obesity along with other risk factors for cardiovascular disease, (b) programs that focus on the prevention of obesity and weight gain, (c) interventions designed to increase physical activity, and (d) eating disorder prevention programs that promote healthy eating and weight management skills (Stice, Shaw & Marti, 2006). This review examines new evidence published in the last ten years with a specific look at school nurse-directed obesity prevention interventions. Key findings from the review include (1) schools face a challenging task implementing activities that have a meaningful impact on child and adolescent obesity trends; (2) adoption of current, evidence-based approaches pose challenges to the schools in time, resources, and training; and (3) there is insufficient evidence to know the full impact of school nurse directed obesity prevention programs. Tackling this issue will require a dedicated and coordinated effort that includes the school, family, and community involvement. Acknowledging this growing public health problem will require schools to identify those students at risk for overweight and obesity and identification will require annual body measurements to include BMI. The school nurse is positioned to provide the coordination needed to make positive changes in childhood obesity. The schools will also need to have resources available to provide referrals for follow-up health-care services for those identified children and the school nurse will need to adopt the role of the liaison between the family and the health care community.

Convex Relaxations of Optimal Power Flow Problems: An Illustrative Example

description: Recently, there has been significant interest in convex relaxations of the optimal power flow (OPF) problem. A semidefinite programming (SDP) relaxation globally solves many OPF problems. However, there exist practical problems for which the SDP relaxation fails to yield the global solution. Conditions for the success or failure of the SDP relaxation are valuable for determining whether the relaxation is appropriate for a given OPF problem. To move beyond existing conditions, which only apply to a limited class of problems, a typical conjecture is that failure of the SDP relaxation can be related to physical characteristics of the system. By presenting an example OPF problem with two equivalent formulations, this paper demonstrates that physically based conditions cannot universally explain algorithm behavior. The SDP relaxation fails for one formulation but succeeds in finding the global solution to the other formulation. Since these formulations represent the same system, success (or otherwise) of the SDP relaxation must involve factors beyond just the network physics. The lack of universal physical conditions for success of the SDP relaxation motivates the development of tighter convex relaxations capable of solving a broader class of problems. Tools from polynomial optimization theory provide a means of developing tighter relaxations. We use the example OPF problem to illustrate relaxations from the Lasserre hierarchy for polynomial optimization and a related "mixed semidefinite/second-order cone programming" hierarchy.

description: In this paper, we study the set of absolute continuity of p-harmonic measure, $μ$, and $(n-1)-$dimensional Hausdorff measure, $\mathcal{H}^{n-1}$, on locally flat domains in $\mathbb{R}^{n}$, $n\geq 2$. We prove that for fixed $p$ with $20=\mathcal{H}^{n-1}(K)$ where $μ$ is the p-harmonic measure associated to a positive weak solution to p-Laplace equation in $Ω$ with continuous boundary value zero on $\partialΩ$. We also show that there exists such a domain for which the same result holds when $p$ is fixed with $2-η0$ provided that $n\geq 3$. This work is a generalization of a recent result of Azzam, Mourgoglou, and Tolsa when the measure $μ$ is harmonic measure at $x$, $ω=ω^{x}$, associated to the Laplace equation, i.e when $p=2$.

description: We discuss the potential of the advanced ground-based gravitational-wave detectors such as LIGO, Virgo, and KAGRA to detect generic deviations of gravitational waveforms from the predictions of general relativity. We use the parameterized post-Einsteinian formalism to characterize the deviations, and assess what magnitude of deviations are detectable by using an approximate decision scheme based on Bayesian statistics. We find that there exist detectable regions of the parameterized post-Einsteinian parameters for different binary masses from the observation of a single gravitational wave event. The regions are not excluded by currently existing binary pulsar observations for the parameterized post-Einsteinian parameters at higher post-Newtonian order. We also find that neglect of orbital eccentricity or tidal deformation effects do not cause a significant bias on the detectable region of generic deviations from general relativity.

description: Unlike crushing singularities, the so-called Type IV finite-time singularity offers the possibility that the Universe passes smoothly through it, without any catastrophic effects. Then the question is if the effects of a Type IV singularity can be detected in the process of cosmic evolution. In this paper we address this question in the context of $F(R)$ gravity. As we demonstrate, the effects of a Type IV singularity appear in the Hubble flow parameters, which determine the dynamical evolution of the cosmological system. So we study various inflation models incorporating a Type IV singularity, with the singularity occurring at the end of inflation. Particularly we study a toy model and a singular version of the $R^2$ gravity Hubble rate. As we evince, some of the Hubble flow parameters become singular at the singularity, an effect which indicates that at that point a dynamical instability occurs. This dynamical instability eventually indicates the graceful exit from inflation. We demonstrate that the toy model has an unstable de Sitter point at the singularity, so indeed graceful exit could be triggered. In the case of the singular inflation model, graceful exit proceeds in the standard way. In the case of the singular inflation model, we found various scenarios for singular evolution, most of which are compatible with observations, and only one leads to severe instabilities. We also compare the ordinary Starobinsky with the singular inflation model, and we point out the qualitative and quantitative differences. Finally, we study the late-time dynamics of the toy model and of the singular inflation model and we demonstrate that the unification of early and late-time acceleration can be achieved. We also show that it is possible to achieve late-time acceleration similar to the $Λ$-Cold Dark Matter model.

description: Studying RS CVn binaries is challenging, because in addition to spot activity, other effects such as mass transfer between the components and gravitational distortion of their spherical forms may distort their light curves. Such effects can, however, be removed from the data by subtracting a mean light curve phased with the orbital period. We study a quarter of a century of standard Johnson differential V photometry of the RS CVn binary BM CVn. Our main aims are to determine the activity cycles, the rate of surface differential rotation and the rotation period of the active longitudes of BM CVn. The Continuous Period Search (CPS) is applied to the photometry. The changes of the mean and amplitude of the light curves are used to search for activity cycles. The rotation period changes give an estimate of the rate of surface differential rotation. The Kuiper method is applied to the epochs of the primary and secondary minima to search for active longitudes. The photometry reveals the presence of a stable mean light curve (MLC) connected to the orbital period P_orb = 20d.6252 of this binary. We remove this MLC from the original V magnitudes which gives us the corrected V' magnitudes. These two samples of V and V' data are analysed separately with CPS. The fraction of unreliable CPS models decreases when the MLC is removed. The same significant activity cycle of approximately 12.5 years is detected in both V and V' samples. The estimate for the surface differential rotation coefficient, k >= 0.10, is the same for both samples, but the number of unrealistic period estimates decreases after removing the MLC. The same active longitude period of P_al = 20d.511 +- 0d.005 is detected in the V and V' magnitudes. This long-term regularity in the epochs of primary and secondary minima of the light curves is not caused by the MLC. On the contrary, the MLC hampers the detection of active longitudes.

An analysis of national, state and instuituional policies that support breastfeeding initiation and duration
Creators: name: Bissell, Amanda

description: Breastfeeding has significant health benefits to both infant and mother. Despite the recognition of such benefits from both the medical and public health community, breastfeeding initiation and duration rates are below the established goals of Healthy People 2020. This is especially true for economically disadvantaged women. This study conducted an analysis of public policies aimed at increasing breastfeeding initiation and duration rates by triangulating primary and secondary data from policy and content experts via interviews and the review of medical and public health literature. Thematic content analysis was used to identify, analyze and report on themes from the interviews and literature. Several commonly reported themes that negatively affect a mother's decision to breastfeed include misinformation on breastfeeding, lack of provider support, and workplace barriers. Commonly reported themes that positively influenced a mother's decision to breastfeed include self-determination, family and provider support, peer counseling, a work environment supportive of breastfeeding, and clinical practices that support the breastfeeding relationship and the mother-baby dyad. These findings provide an opportunity for public health leaders to promote those positive influences and address barriers through the lens of the socio-ecologic model, spanning policy to community and individual interventions. These opportunities include clarifying and enforcing existing regulations, advocating for a national paid family leave program, a mandate that hospitals adopt clinical practices supportive of breastfeeding, and support for peer counselor programs.

description: Since 1994 the Internet has grown into an information source that reaches out to audiences in ways that traditional print media never did, passes information around the globe in seconds, and connects individuals and information with an ease that seemed unimaginable in prior years. This phenomenon has led to the rise of"e-health" -the merger of technology and health related topics. This paper discusses how the Internet as a form of population health technology has benefited four of the ten essential services of public health. Use of Internet technology has had the most dramatic influence on the services to: inform, educate and empower people about health issues (#3), diagnose and investigate health problems and health hazards in the community (#2), assure a competent public health and personal health care workforce (#8), and research for new insights and innovative solutions to health problems (#10) (Public Health Function Steering Committee). In each of these areas the increase is easily accessible, widely available information and access has increased the efficiency with which public health functions.
