Fano resonances and entanglement entropy

We study the entanglement in the ground state of a chain of free spinless fermions with a single side-coupled impurity. We find a logarithmic scaling for the entanglement entropy of a segment neighboring the impurity. The prefactor of the logarithm varies continuously and contains an impurity contribution described by a one-parameter function, while the contribution of the unmodified boundary enters additively. The coefficient is found explicitly by pointing out similarities with other models involving interface defects. The proposed formula gives excellent agreement with our numerical data. If the segment has an open boundary, one finds a rapidly oscillating subleading term in the entropy that persists in the limit of large block sizes. The particle number fluctuation inside the subsystem is also reported. It is analogous with the expression for the entropy scaling, however with a simpler functional form for the coefficient.Comment: 10 pages, 10 figures, minor change

A MULTI-COMPONENT EDUCATION, SKILL, AND RESOURCE EVIDENCE-BASED PRACTICE INTERVENTION FOR THE ALZHEIMER’S CAREGIVER

Abstract Dementia caregiving is expensive, stressful, and consumes all facets of the caregiver’s (CGs) life. The purpose of this project is to introduce the evidence-based practice (EBP) interventions most helpful in decreasing stress and burden in those who are in-home caregivers for Alzheimer’s disease and related dementias (ADRD) individuals. The three primary intervention domains of the EBP studies that results in a positive impact are; providing education about the terminal course of the disease, introducing communication and caregiving skills, and furnishing resource and social network information. The methodology included a convenient and voluntary population of CGs who sought service at a community dementia organization. The staffing team led by social workers, implemented the multi-component program over 1 – 2 months. Intervention sessions consisted of home safety assessments, legal and medical information, social support, managing stress, understanding caregiver feelings, skillful communications, relating memory problems to behavior, and additional resources helpful to the care of the dementia individual. A Risk Assessment Measure (RAM) tool was used to measure CG stress and burden level before and after all the interventions were complete. Analysis of the data showed that the mean Pre-RAM score was 21.7, and the mean Post-RAM score was 12.6, a reduction of 9.1 points indicating an overall decrease in stress and burden. Further analysis was performed for significance level using a two-tailed hypothesis. The data concludes that educating the caregiver using a multi-component approach can reduce the stress and perceived burden of dementia caregiving. To ensure sustainability, the clinical site’s policy change is to offer the program to CGs who present with moderate to high levels of stress as measured by the RAM assessment. To monitor sustainability, an annual audit of the program will be submitted to the Board of Directors. The audit includes the number of participants and the analysis of RAM data

World View & Correlates of Communication Behaviors

This study examined the relationship of world view to selected communication, demographic, and social variables. Using a newly developed scale for world view, the researcher tested one hundred forty-nine high school and college level subjects to determine significant interactions between world view and communication apprehension, use of mass media, trust, life satisfaction, social participation, age, grade level, sex, income, and race. Data analyses included factor analyses, analyses of variance, and correlation and regression analyses. Results of the simple correlation indicated that the age-grade combination was the strongest single factor followed by income, religious participation, television watching, sex, newspaper reading, radio listening, and communication apprehension. Generally, the ANOVA showed that the college level student had a higher world view than the high school student; that with one exception males had a higher world view than females; that low religious participation almost consistently accompanied a higher world view than high religious participation, that low television watching accompanied high world view; that low income males showed higher world view than high income males, while income failed to show any affect on females; and that communication apprehension interacted with world view in conjunction with religious participation and sex in a complicated pattern. No significant interaction was detected with world view and race, world view and trust, or world view and life satisfaction
