Emulsions, Photochemistry, and Processing Factors for Display Holograms
This article reviews the range of emulsions, photochemistry, and processing techniques that have been proposed and put into practice for the successful making of display holograms. It covers various types of media including gelatin-based emulsions and photopolymers (it focuses on the former) and considers external factors that affect the final results. This is a compact review of the history of the field but focuses on the range of easily available commercial emulsions, as well as certain accounts of how to make holographic emulsions from scratch. It considers various combinations of developer, bleach, and redeveloper, which have been used to achieve the best of various trade-offs for such factors as resolution, contrast, diffraction efficiency, clarity, color quality, blackest blacks, and resistance to printout. It describes a recent advance in hypersensitizing holographic emulsions
The Corruption of the Pardon Power
This Article shows how the pardon power has been corrupted over the past forty years. It begins with a brief history of federal clemency. Throughout this history, presidents gave weight to the views of prosecutors and judges and afforded politicians considerable influence. Nevertheless, until well into the twentieth century, presidents liberally granted clemency to both prisoners and ex-offenders who, after completing their sentences, sought to erase their convictions.
In the early 1930s, as parole became a common means of releasing prisoners, the use of clemency to release prisoners declined. The abolition of parole in the 1980s, however, brought no revival of clemency. To the contrary, sentence commutations continued to fall and came close to the vanishing point. For the first time in its history, the United States had no functioning mechanism for releasing prisoners prior to the expiration of their sentences, and the federal prison population burgeoned. The last two years of the Obama administration did see a brief departure from this pattern.
As the front door to clemency closed, a back door opened. Presidents who emphasized how little sympathy they had for criminals took a different view when the criminals were people they knew. This Article describes troubling pardons granted by Presidents Reagan, George H. W. Bush, Clinton, and George W. Bush. The Article focuses primarily, however, on the clemency granted by President Trump. While thousands of clemency applications remained unresolved, Trump granted clemency to potential witnesses against him, political supporters, personal friends, people with political constituencies, rap stars, abusive law enforcement officers, war criminals, and people whose applications were championed by movie stars, professional athletes, and Fox News commentators. The Article describes many of Trump’s pardons and commutations. It concludes by asking whether the Framers erred by granting a nearly unfettered power to the president
College integrated care: Effectiveness of the use of a modified version of the patient health questionnaire for patients in a university health clinic
In primary medical care settings, problems with providing appropriate behavioral care led to development of the integrated care model providing behavioral services alongside medical services. The present study explored the potential need for this model at a Midwest university health center, by investigating how two behavioral questionnaires influenced providers’ prescription of psychotropic medications and referrals for behavioral intervention. After random assignment to condition, 109 participants in the experimental condition completed the mentalhealth- oriented Patient Health Questionnaire and the college-adjustment-oriented College Health Questionnaire, and 91 control participants received treatment as usual. Results indicated significantly higher rates of discussion of behavioral problems and prescription of psychotropic medications (not behavioral referrals) for the experimental condition. Patients in the experimental condition and providers both indicated a desire to use the questionnaires in future visits. These findings suggest that university health services would be fertile ground for implementation of an integrated care model
Two Guns, Four Guns, Six Guns, More Guns: Does Arming the Public Reduce Crime Juvenile Crime?
Faculty Inter - Rater Reliability of a Reflective Journaling Rubric -- RESEARCH
There has been a lack of research regarding faculty training in the grading of student reflective journals (RJs). Whether or how one should evaluate RJs remains contentious. This quasi-experimental study assessed whether providing faculty in-service training on scoring RJs using a rubric would result in statistically significant inter-rater reliability.Prior to the study, faculty raters received training on reflective practice and scoring RJs with a rubric based on five levels of reflection. Percent agreement between rater pairs, with 80% set as the inter-rater reliability benchmark, was utilized. Faculty raters scored anonymous BSW and MSW RJs assigned in cultural diversity and oppression courses. Expected learning outcomes included critical and reflective thinking; social justice; application and synthesis of classroom learning to social work practice; ethical awareness; and self-awareness. Fifty percent of RJs collected twice over one term were selected randomly. One faculty pair was selected by chance and assigned under blinded conditions to score either BSW or MSW RJs. Inter-rater reliability of BSW RJ scores ranged from 86% for the first set to 98% for the second set. For the MSW RJs, scores ranged from 85.5% to 83.2%. These findings were all statistically significant and indicated that, with prior training on the purpose of RJs and in using a rubric, faculty may be better able to evaluate RJs fairly
