Evolution and Epiphany: Language in Biological and Theological Perspective
Brief sketches are given, on the one hand, of three \"biological\" accounts of human
language that construe its function in terms of evolutionary adaptation, and, on the other
hand, of three \"theological\" accounts of language that construe its function in terms of
human relatedness to God. The theological accounts, when placed into conversation with
the biological accounts, are allowed to raise specific critical questions and suggestions for
further work, in an attempt to contribute methodologically and materially to the ongoing
dialogue between science and religion
Absolute gain measurement by the image method under mismatched condition
Purcell's image method for measuring the absolute gain of an antenna is particularly attractive for small test antennas. The method is simple to use and utilizes only one antenna with a reflecting plane to provide an image for the receiving antenna. However, the method provides accurate results only if the antenna is matched to its waveguide. In this paper, a waveguide junction analysis is developed to determine the gain of an antenna under mismatched condition. Absolute gain measurements for two standard gain horn antennas have been carried out. Experimental results agree closely with published data
A Generic Qualitative Inquiry of the Challenges for Black African American Men who have Experienced Trauma
Black African American Men (BAAM) suffer disproportionately from trauma related challenges and have a higher risk of encountering trauma across the lifespan. The negative impact of trauma is a major public health concern in the United States, evidence suggests trauma negatively impacts the physical well-being, mental health, and mortality rate. BAAM have increased rates of trauma exposure and their traumatic experience is historically complex involving a variety of contemporary issues (i.e. Adverse Childhood Experiences (ACEs), depression, victimization and desensitization, stress). This research aims to explore the complex nature of their trauma-related challenges among a purposeful sample of BAAM participants in Arkansas using a generic qualitative inquiry. The study will use an adapted conceptual framework of Historical Trauma Theory (HTT) to anchor the researcher within the analyses the data to answer the question: âWhat are the challenges for BAAM who have experienced trauma?â Analysis of the descriptive data (e.g., interviews, observations, documents) aspires to expand the body of knowledge, to elucidate culturally congruent perspectives, and encourage improvement of trauma informed care among key stakeholders
Level of Performance of Wardsâ Staff Nurses in Rendering Care among TB Patients in Selected Government Hospitals in Fourth District of Quezon Province: Basis for Enhancement
Knowledge and understanding of Tuberculosis (TB) is essential in rendering quality care to all individuals, since Nursing is a profession of caring individuals from womb to tomb. This research is about the level of performance of staff nurses on their rendering care among TB patients in the wards. It is quantitative and comparative which covered 22 staff nurses and five head nurses from selected government hospitals in Quezon province. They were selected using purposive sampling. The profile of staff nurses includes gender, age, and length of service. The head nurses are all female and in their late adulthood. The study was conducted in Guinayangan Medicare Community Hospital, Maria L. Eleazar District Hospital, and Magsaysay Memorial District Hospital. The respondents answered the adapted questionnaires from the Orientation of Hospitals on Benchbook Self-Assessment and Accreditation Process Manual II 2005 of Philippine Health Insurance Corporation which was modified by the researcher into two questionnaires and were validated by experts. The questionnaire for staff nurses had a reliability result of 0.97 and 0.99 for head nurses respectively using Cronbach Alpha. Statistical treatments that were utilized includes: frequency and percentage, mean, standard deviation, and independent sample t-Test. The result elucidated that there was no significant difference in their perceived level of performance in rendering care among TB patients in the wards when their profiles were considered. It can also be concluded that there was no significant difference between the perception of the head nurses and the staff nurses on their level of performance in rendering care among TB patients in the wards. Moreover, enhancement program pertaining to Evaluation of Care, Access, and Assessment through trainings and seminars were include
A Computer Modeling Approach to Understanding the Inferior Olive and Its Relationships to the Cerebellar Cortex in Rats
This paper presents the results of a simulation of the spatial relationship
between the inferior olivary nucleus and folium crus IIA of the lateral
hemisphere of the rat cerebellum. The principal objective of this
modeling effort was to resolve an apparent conflict between a proposed
zonal organization of olivary projections to cerebellar cortex suggested
by anatomical tract-tracing experiments (Brodal & Kawamura 1980;
Campbell & Armstrong 1983) and a more patchy organization apparent
with physiological mapping (Robertson 1987). The results suggest that
several unique features of the olivocerebellar circuit may contribute to
the appearance of zonal organization using anatomical techniques, but
that the detailed patterns of patchy tactile projections seen with
physiological techniques are a more accurate representation of the
afferent organization of this region of cortex
Targeting proteinâprotein interactions within the cyclic AMP signaling system as a therapeutic strategy for cardiovascular disease
The cAMP signaling system can trigger precise physiological cellular responses that depend on the fidelity of many proteinâprotein interactions, which act to bring together signaling intermediates at defined locations within cells. In the heart, cAMP participates in the fine control of excitationâcontraction coupling, hence, any disregulation of this signaling cascade can lead to cardiac disease. Due to the ubiquitous nature of the cAMP pathway, general inhibitors of cAMP signaling proteins such as PKA, EPAC and PDEs would act non-specifically and universally, increasing the likelihood of serious âoff targetâ effects. Recent advances in the discovery of peptides and small molecules that disrupt the proteinâprotein interactions that underpin cellular targeting of cAMP signaling proteins are described and discussed
