Stability of the proton-to-electron mass ratio

We report a limit on the fractional temporal variation of the proton-to-electron mass ratio as, obtained by comparing the frequency of a rovibrational transition in SF6 with the fundamental hyperfine transition in Cs. The SF6 transition was accessed using a CO2 laser to interrogate spatial 2-photon Ramsey fringes. The atomic transition was accessed using a primary standard controlled with a Cs fountain. This result is direct and model-free

The Influence of pH Variation on CooA Activity

CooA, a CO-sensing heme protein, acts as a transcriptional activator of CO-metabolizing proteins in bacteria such as Rhodospirillum rubrum and Carboxydothermus hydrogenoformans through sequence-specific DNA binding. Previous research indicated a reduced iron center and CO gas were necessary for CooA to achieve its active conformation and bind DNA. To determine if other reaction conditions facilitate CooA activation, the role of pH on CooA function was tested. Specifically, a fluorescence anisotropy assay was employed to measure possible Fe(III) CooA DNA binding from pH 3 - 12. Interestingly, CooA was observed to bind DNA without CO at acidic conditions, with optimal binding observed at pH ~3. These results are discussed in light of the normal CO-dependent activation mechanism of CooA proteins

Differences in Dropout Rates as a Function of High School Size for Students in Poverty: A Texas Multiyear, Statewide Study

Child poverty in the United States, with regard to student achievement, has grave challenges for the children who face poverty (Scott & Pressman, 2013). Not only is living in poverty associated with lower academic achievement, but student poverty is also associated with lower rates of school completion (Borg, Borg, & Stranahan, 2012; Cooper & Crosnoe, 2007; Kena et al., 2015). Consequentially, students who do not complete high school are more likely to (a) serve time in prison, (b) need government assistance, and/or ( c) die at an earlier age (Messacar & Oreopoulos, 2013). With the increasing number of children who are living in poverty, child poverty is an issue that needs to be at the forefront of the educational agenda (Tienken, 2012)

Publication rates on the topic of racial and ethnic diversity in dermatology versus other specialties

Background: The population of the U.S. is becoming more diverse every year. The field of dermatology is not following the same trend. Objective: To assess the promotion of diversity in the field of dermatology by analyzing publications focused on diversity, compared to other specialties. Methods: The PubMed database was systematically searched to identify publications focused on diversity from January 2008 to July 2019. The search criteria were as follows: dermatology/radiology/ophthalmology/ anesthesiology/orthopedic surgery/family medicine/ internal medicine/general surgery AND diversity/ diverse/racial/race/ethnic/ethnicity/cultural/culture/competency/competence. Comparisons were made using single-factor ANOVA and two-group t-tests. A qualitative analysis was performed for publications in the field of dermatology. Results: From January 2016 to July 2019, there were 25 publications focused on diversity in dermatology (Mean=6.25, SD=2.06), compared to 6 in radiology (Mean=1.50, SD=1.29, P=0.01), two in ophthalmology (Mean=0.50, SD=0.58, P=0.01), two in anesthesiology (Mean=0.50, SD=1.00, P=0.01), 12 in orthopedic surgery (Mean=3.00, SD=1.41, P=0.04), 23 in family medicine (Mean=5.75, SD=2.22, P=0.75), 9 in internal medicine (Mean=2.25, SD=1.71, P=0.02), and 7 in general surgery (Mean=1.75, SD=0.50, P=0.02). Conclusions: Although the field of dermatology has suffered from a lack of racial/ethnic diversity, efforts to promote diversity via increased publications in the last four years have been stronger in dermatology compared to many other fields

Forgiveness Motives Among Evangelical Christians: Implications for Christian Marriage and Family Therapists

Therapists and researchers interested in forgiveness can learn from those who have experienced interpersonal wounds and have chosen to forgive. We interviewed 20 evangelical Christian forgivers, asking about motives for forgiveness. Transcripts were analyzed using qualitative methods. Five categories of motivation are presented: comfort, duty, relational, humility/empathy, and Christian beliefs. Respondents described multiple motives for forgiveness, often combining a desire for comfort or a sense of duty with their Christian beliefs. Four implications for Christian marriage and family therapists are discussed: Expect diversity, avoid moralistic views of motives, remember religious resources in the forgiveness process, and expect benefits, but not immediately

Collaboration through Research: The Multimethod Church-Based Assessment Process

The Multimethod Church-Based Assessment Process (MCAP) is a systematic assessment and consultation process developed to help congregations to better understand needs, resources, and ministJy successes. Con. sultation with the MCAP is best understood as a relational endeavor that requires collaboration between the church leadership team and a mental health professional skilled in consultation methods, data analysis, and research methods. Potential uses and limitations of the MCAP are described

Professional Development Needs of Mid-Career Agriculture Teachers

Nationwide, agricultural education faces a shortage of teachers (National Teach Ag Campaign, 2014; Foster, Lawver, & Smith, 2016). To remedy this, both recruitment and retention efforts are necessary. While extensive research in agricultural education has focused on needs of beginning teachers, less research has focused on needs of agriculture teachers at later career stages. As such, the purpose of this phenomenological qualitative study was to explore challenges, activities, and professional development needs of mid-career agriculture teachers, particularly those within the “Experimentation/Activism” and “Reassessment/Self-Doubt” stages identified by Huberman (1989). The study narrowly focused on a census of 35 teachers from across the country who applied for a professional development program designed for mid-career agriculture teachers. Mid-career teachers identified lack of time, course planning, and programmatic expectations as challenges or obstacles. The teachers reported a desire to fulfill professional development needs by networking, reenergizing, and improving stress management. Specifically, teachers reported participating in professional organizations, joining teacher listservs, and networking through the National Association of Agricultural Educators’ Communities of Practice for engagement and support. Findings suggest continued professional development offerings and additional research related to mid-career agriculture teacher well-being are warranted

Teaching Integration outside the Traditional Classroom

Today\u27s educational environment is being transformed by online technologies that open new venues for teaching and make education accessible far beyond the traditional classroom environment. How rrught these changes affect the ways we teach the integration of psychology and Christianity? Three faculty members dialogue about such integration opportunities, advantages, and potential disadvantages
