Color-blind racial attitudes: Microaggressions in the context of racism and White privilege

Interest in institutional racism, White privilege, and microaggressions appears to be growing. We are living in times when the impact of race and racism are debated—when even the existence of racism is debated along with the appropriateness of examining the worst parts of U.S. history. This special-issue invited article includes a brief examination of historical information and current context in which racism and microaggressions exist, leading to their connections to Color-Blind Racial Attitudes (CoBRAs). Reviewed research on CoBRAs addresses teacher training, educational practices, experiences on college campuses, and organizational management

REMOVAL OF MANGANESE FROM AN ALKALINE MINE DRAINAGE USING A BIOREACTOR WITH DIFFERENT ORGANIC CARBON SOURCES

The treatment of Mn and SO42- contaminated mine drainage via a sulfate reducing bioreactor is expected to result in near-permanent immobilization of significant amounts of Mn and a portion of the sulfates within the matrix. This study tested several different combinations of organic amendments and inorganic substrates in an attempt to optimize sulfate reducing conditions and Mn removal capacity. Five different organic carbon sources, including corn mash, wood mulch, biosolids, soybean oil, and sorghum syrup in combination with five different inorganic substrates, including creek sediment, marble and limestone chips, polished gravel, and sand were tested in batch experiments. Results indicate a widely Mn variant removal potential among the treatments, ranging from 35% for soybean oil to 97% for the mulch mixture, with respective Eh ranges of +60 mV and -320 mV. Sulfate removal ranged from less than 10% to 85%. The most favorable combinations were tested in small scale bioreactors under dynamic conditions. Greater than 90% of Mn and 70% of sulfate was removed over a 65 day test period. Results indicate Mn removal mechanisms include sulfide, oxide, and carbonate formation and simple sorption and SO42- removal mechanisms of sulfide gas evolution, gypsum and MnS precipitation, and anion sorption/cation bridging

Career Barriers in Freshman Orientation: What are first year students worried about?

The goal of this study was to identify the career barriers facing college students in their first semester with the possibility of addressing those concerns through campus programing or freshman orientation

Integration and Conventional Systems at STAR

At the beginning of the design and construction of the STAR Detector, the collaboration assigned a team of physicists and engineers the responsibility of coordinating the construction of the detector. This group managed the general space assignments for each sub-system and coordinated the assembly and planning for the detector. Furthermore, as this group was the only STAR group with the responsibility of looking at the system as a whole, the collaboration assigned it several tasks that spanned the different sub-detectors. These items included grounding, rack layout, cable distribution, electrical, power and water, and safety systems. This paper describes these systems and their performance.Comment: 17 pages, 6 figures, Contribution to a NIM Volume Dedicated to the Detectors and the Accelerator at RHI

Presenting Information About White Privilege and Systemic Racism: Message vs. Messenger

In our study, we found evidence for some effect on how students perceive information about systemic racism and White privilege based on the perceived identity of the presenter

How Students View Diversity in Their Education: A Qualitative Examination

In this study, we examined students’ open responses to questions regarding their opinions about diversity on their college campus. Here, we report on responses about age, religion, and political views in the classroom and outside the classroom

Career Decision Self-Efficacy Assessment: Are scores consistent across two administration formats?

The correlations between the two different forms of the CDSE-SF were high, supporting, alternate form reliability between different administration formats

Annual Timing of Elk Abortions and Potential Brucellosis Risk

The transmission of Brucella abortus, the bacteria causing brucellosis, occurs through abortion events. In this study, we investigated the timing of those abortion events using vaginal implant transmitters (VITs) in pregnant elk (Cervus elaphus) from the Jackson and Pinedale regions of Wyoming. From 2006 to 2013, we captured 463 pregnant female elk and 136 of those were seropositive (29%, 95% CI = [25, 34]). We had a total of 29 abortion events with 20 percent (95%CI = [13, 29]) of seropositive elk aborting compared to 2.2 percent (95% CI =[0.8, 4.5]) of seronegative elk aborting. VIT data are left-truncated, right and interval censored. We analyzed these data in a Bayesian framework borrowing from the survival analysis literature to estimate the baseline hazard and how it changes during the year. When we conducted a joint analysis of both abortions and births our preliminary results indicated that elk abortions are concentrated in March and April. Only three abortions occurred after 20 May  and one may have occurred as late as 10 July. These results are relevant to mitigating the risk of transmission between elk and cattle. Future work can build upon these results to assess the amount of brucellosis transmission risk during the winter on private land compared to public grazing allotments, which are used later in the year
