VIETNAM VETERANS AND ILLICIT DRUG USE

This study examined the correlation between Vietnam veterans and dependency to illicit drugs, due to their exposure and accessibility during their deployment in Vietnam. This study consisted of a sample size of 58 respondents to a survey that was disbursed throughout 2 agencies that comprise of Vietnam veterans.The survey design was implemented to ensure the consistency and accuracy of the quantitative data. Furthermore, this study included a Chi-square test to determine relevance and implications to micro social work practices. As expected, there was a positively significant statistical relationship between the exposure and accessibility that some Vietnam veterans experienced during their deployment that continues to affect their current use of illicit drugs. This study has been conducted to help future micro practitioners understand the importance and effects that this exposure and accessibility played in the lives of many Vietnam veterans

Transformational Leadership: An Urban Leaders\u27 Autoethnography

My story of lived experiences is told through a transformational leadership lens whereby the leader is charged with identifying the need for change, creating the vision to guide the change through inspiration and executing the change in tandem with committed members of the group. An autoethnography is a style of autobiographical writing that explores an individual\u27s unique life experiences in a natural setting. The researchers\u27 lived experiences are scholarly and justifiable interpretations supported by multiple sources of evidence and artifacts

A Geographic Information Systems Approach to the 19th Century Excavation of Brixham Cavern, Devon, England

The oldest known spatially-explicit archaeological excavation, conducted in Brixham cave, Devon, in 1858, is reconstructed using geographic information systems technology. Two dimensional plots of individual fossil taxa and flint artefacts demonstrate the utility of the technique for elucidating taphonomy and palaeobiology. The cave served as a den for hibernating brown bears, as a den for hyena and cave lion, and as a reliquary for their prey

The use and measurement of communication self-efficacy techniques in a UK undergraduate accounting course

This research contributes to helping educational establishments across the world develop self-efficacy techniques to improve communication skills within an accounting course design and other disciplines. This paper asks the research question: Does self-efficacy enhances accounting students’ communication ability? Previous research has identified the business community requiring accountants to display high levels of communication ability. However, despite many deliberate pedagogical interventions over the years, communication skills are lacking in graduating accounting students. This paper describes a new approach of deliberate self-efficacy interventions in one UK university’s undergraduate accounting curriculum to improve accounting students’ communication ability. In addition, a self-efficacy framework of Stone and Bailey [(2007). Team conflict self-efficacy and outcome expectancy of business students. Journal of Education for Business, 82(5), 258–266. https://doi.org/10.3200/JOEB.82.5.258-266.] is developed to model communication self-efficacy, outcome expectancy and behavioral intentions of the students. The data consists of the results of 131 first-year accounting students, and this paper contributes by helping to pinpoint two self-efficacy techniques to improving students’ communication skills: ‘personal mastery’ and ‘mentor support’

Best Practices in Second Stage Labor Care: Maternal Bearing Down and Positioning

Despite evidence of adverse fetal and maternal outcomes from the use of sustained Valsalva bearing down efforts, current second-stage care practices are still characterized by uniform directions to “push” forcefully upon complete dilatation of the cervix while the woman is in a supine position. Directed pushing might slightly shorten the duration of second stage labor, but can also contribute to deoxygenation of the fetus; cause damage to urinary, pelvic, and perineal structures; and challenge a woman’s confidence in her body. Research on the second stage of labor care is reviewed, with a focus on recent literature on maternal bearing down efforts, the “laboring down” approach to care, second-stage duration, and maternal position. Clinicians can apply the scientific evidence regarding the detrimental effects of sustained Valsalva bearing down efforts and supine positioning by individualizing second stage labor care and supporting women’s involuntary bearing down sensations that can serve to guide her behaviors

Assessment of cold neutron radiography capability

This is the final report of a one-year, Laboratory Directed Research and Development (LDRD) project at Los Alamos National Laboratory (LANL). The authors goals were to demonstrate and assess cold neutron radiography techniques at the Los Alamos Neutron Science Center (LANSCE), Manual Lujan Neutron Scattering Center (Lujan Center), and to investigate potential applications of the capability. The authors have obtained images using film and an amorphous silicon detector. In addition, a new technique they have developed allows neutron radiographs to be made using only a narrow range of neutron energies. Employing this approach and the Bragg cut-off phenomena in certain materials, they have demonstrated material discrimination in radiography. They also demonstrated the imaging of cracks in a sample of a fire-set case that was supplied by Sandia National Laboratory, and they investigated whether the capability could be used to determine the extent of coking in jet engine nozzles. The LANSCE neutron radiography capability appears to have applications in the DOE stockpile maintenance and science-based stockpile stewardship (SBSS) programs, and in industry

Macrostrain measurement using radial collimators at LANSCE

A series of `short` radial collimators have been implemented in the 90{degrees} scattering geometries on the neutron powder diffractometer at Los Alamos. The capability to perform macrostrain measurements has been improved by the commensurate ability to rapidly select a sampling volume appropriate to the specimen. The compact design of the collimators was dictated by the need to fit them in a cylindrical vacuum chamber as well as providing space in which to manipulate a specimen in three dimensions. Collimators of different vane lengths were fabricated to give 4 different resolutions for which 2/3 of the diffracted intensity comes form distances of 0.75, 1. 25, 2.5, and 4.0 mm along the incident beam. Qualifying scans and a demonstration of a cracked ring, containing a steep stress gradient, are included

Design and Implementation of an X-Ray Strain Measurement Capability Using a Rotating Anode Machine

This is the final report of a three-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). Residual stresses close to the surface can improve the reliability and lifetime of parts for technological applications. X-ray diffraction plays a significant role in gaining an exact knowledge of the stresses at the surface and their depth distribution. An x-ray capability at Los Alamos is key to developing and maintaining industrial collaborations in strain effects. To achieve this goal, the authors implemented a residual strain measuring station on the rotating anode x-ray instrument at the Lujan Center. This capability has been used to investigate residual strains in heat treated automotive components, machining effects on titanium alloys, resistance welded steel joints, titanium matrix fiber reinforced composites, ceramic matrix composites, thin films, and ceramic coatings. The overall objective is to combine both x-ray and neutron diffraction measurements with numerical models (e.g., finite element calculations)

A Critical Appraisal of Guidelines for Antenatal Care: Components of Care and Priorities in Prenatal Education

There are a variety of published prenatal care (PNC) guidelines that claim a scientific basis for the information included. Four sets of PNC guidelines published between 2005 and 2009 were examined and critiqued. The recommendations for assessment procedures, laboratory testing, and education/counseling topics were analyzed within and between these guidelines. The PNC components were synthesized to provide an organized, comprehensive appendix that can guide providers of antepartum care. The appendix may be used to locate which guidelines addressed which topics to assist practitioners to identify evidence sources. The suggested timing for introducing and reinforcing specific topics is also presented in the appendix. Although education is often assumed to be a vital component of PNC, it was inconsistently included in the guidelines that were reviewed. Even when education was included, important detail was lacking. Addressing each woman\u27s needs as the first priority was suggested historically and remains relevant in current practice to systematically provide care while maintaining the woman as the central player. More attention to gaps in current research is important for the development of comprehensive prenatal guidelines that contribute effectively to the long‐term health and well‐being of women, families, and their communities

Time-of-Flight Spectroscopy of 252 Cf Spontaneous Fission Neutrons:Influences of Detector Voltage, Pulse-Shape Discrimination and Shielding

Experimental measurements to explore the effect of detector voltage, pulse-shape discrimination (PSD) threshold and detector shielding on time-of-flight measurements of the 252Cf neutron spectrum made with organic scintillation detectors are described. It is found that detector voltage has a major effect, whilst changing the PSD threshold and shielding the detectors to optimize sensitivity to the desired gamma-neutron correlation results in a small effect
