In the Eye of the Interviewer

Though unemployment was low across the United States at 3.3% in 2019, it was almost double that for Black people at 5.4% in 2019 (https://www.bls.gov/web/empsit/cpsee_e16.htm). Because the interviewer’s attention to the eyes of a job candidate produces a better understanding of the candidate, it is possible that identifying racial bias in eye contact during the interview process could reduce racial disparities in unemployment. We will investigate how attention to the candidate’s eyes moderates race and gender disparities in hiring decisions. Participants will look at either a White man, Black man, White woman, or Black woman who is ostensibly a job candidate while listening to a supposed recording of that candidate during a job interview. Notably, participants will listen to the same male voice recording regardless of the race of the man and will listen to the same female voice recording regardless of the race of the woman. While participants listen to the recording, we will track where their eyes focus. We predict for the White male candidate high attention to the candidate’s eyes during the interview will lead to high interview scores, whereas low attention to the eyes will lead to low scores. For the White female candidate, we predict less attention to the eyes than the White male candidate, as well as lower interview scores. For the Black male and female candidates, we expect low interview scores, but no difference based on attention to the eyes. Future research should examine what causes racial disparities in attention to the eyes

Bioenergetics analysis of ammonia-oxidizing bacteria and the estimation of their maximum growth yield

The currently accepted biochemistry and bioenergetics of ammonia-oxidizing bacteria (AOB) show an inefficient metabolism: only 53.8% of the energy released when a mole of ammonia is oxidised and less than two of the electrons liberated can be directed to the autotrophic anabolism. However, paradoxically, AOB seem to thrive in challenging conditions: growing readily in virtually most aerobic environment, yet limited AOB exist in pure culture. In this study, a comprehensive model of the biochemistry of the metabolism of AOB is presented. Using bioenergetics calculations and selecting the minimum estimation for the energy dissipated in each of the metabolic steps, the model predicts the highest possible true yield of 0.16 gBio/gN and a yield of 0.13 gBio/gN when cellular maintenance is considered. Observed yields should always be lower than these values but the range of experimental values in literature vary between 0.04 and 0.45 gBio/gN. In this work, we discuss if this variance of observed values for AOB growth yield could be understood if other non-considered alternative energy sources are present in the biochemistry of AOB. We analyse how the predicted maximum growth yield of AOB changes considering co-metabolism, the use of hydroxylamine as a substrate, the abiotic oxidation of NO, energy harvesting in the monooxygenase enzyme or the use of organic carbon sources

A Culture of Mattering: Building Staff Belonging, Purpose and Meaning at an Indigenous Recovery Centre

The Ngwaagan Gamig Recovery Centre/Rainbow Lodge on the Wikwemikong Unceded Reserve in Ontario, Canada provides culturally-based alcohol and drug addiction treatment. We seek to support the staff’s sense of belonging and mattering, and engagement with their leader’s vision to incorporate positive psychology into the culture of the centre. Indigenous culture is being leveraged to heal from within after a history of oppression and cultural genocide in Canada (TRCC, 2015). Informed by the inherent resilience of the Anishinaabe people and culture, and current psychological science, we propose two positive interventions to cultivate mattering among staff. We recommend a peer support framework to establish a foundation of connection, and accompanying storytelling interventions grounded in Indigenous cultural practices. The literature emphasizes storytelling and cultural identity as essential for building resilience and belonging in Indigenous communities, especially for those dealing with addiction. We build upon current storytelling initiatives at Rainbow Lodge and incorporate Anishinaabe culture. We suggest culturally relevant measurement through talking circles and tools already used by the Rainbow Lodge to measure impact. We believe the proposed applications will enhance among the staff a sense of individual and community belonging, purpose and mattering, resulting in a willingness to participate and contribute to new initiatives, and overall increased well-being

All possible (nonequivalent) factor systems are determined using the Mac Lane method. Some of resulting groups describe magnetic translation groups. As examples extensions with G=U(1) and G=Z_n are considered and discussed.Comment: 10 page

East Atlanta

Prepared by the Spring 2017 Case Studies in Historic Preservation students. Located partially in the City of Atlanta, DeKalb County and in unincorporated DeKalb County. East Atlanta is a good example of an evolving suburb. In the late 19th and early 20th century the area was an urban neighborhood that relied on the streetcar system and by World War II had evolved into an automobile-reliant suburban. Development progressed from a densely, gridded street pattern in the northern portion indicating a traditional urban neighborhood to a curvilinear street pattern in the southern section indicating an automobile-centric suburb. The area includes at least three commercial nodes, a variety of historic houses and community and commercial buildings, a cemetery, a park, a Civil War monument, and five state historic markers.https://scholarworks.gsu.edu/history_heritagepreservation/1048/thumbnail.jp

An African-American Resources and Needs Assessment of the West Bloomington Area, Phase 1

Over the course of the Fall 2009 semester, students in the Community Project Design and Management class worked with members of West Bloomington to recognize the growing needs within the community. Along with the African-American Focus Workgroup (AAFW) and the West Bloomington Revitalization Partnership (WBRP), the students completed Phase 1 of an African-American resources and needs assessment resulting in this report. This document reflects needs, wants, and hopes of the West Bloomington community and the AAFW. Comprehensively, this document is meant to serve as a bridge between community members and AAFW members. As Bloomington as a whole continues to grow and expand, some members within the community feel the difficulty of being left out of development. Therefore, the project‟s purpose was to help ascertain the assets and deficiencies within the West Bloomington neighborhood with the participation of community members, and to help the AAFW integrate their goals with those of the WBRP. This report can aid future efforts and provide useful information in the development of the West Bloomington area. The report includes a brief review of the literature considering race, education, income, age, public space, housing, civil society, and community-based participatory research. The report also includes sections outlining the research methods used, the research findings along the same themes used in the literature review, a discussion of limitations and barriers to research, and conclusions and recommendations. Appendices include Institutional Review Board (IRB) protocol for ethical treatment and protection of research participants, definition of the study area for drawing out Census data, and a Survey Design and Administration Protocol Handbook to aid in administering surveys drafted for AAFW member organizations to use with their staff and volunteers, patrons, and the general public. Student researchers analyzed public data and local reports to understand the background and demographics of the West Bloomington community. Reports consulted include these topics: housing conditions and issues; food justice; Census data on race, income, and age; community and economic development; and education statistics for District 87 and West Bloomington schools. Through various focus groups, four common themes appeared: the need for greater communication between and among local organizations and community members; the need for additional activities, especially for young people; a lack of accessibility to various services offered by (or in) the City of Bloomington and surrounding areas; and distressed amenities. Communication can be strengthened between the WBRP and the AAFW, between West Bloomington community members and the City of Bloomington, and among all of these groups and members. Focus group findings also show that the West Bloomington community and organizations serving it do not offer activities to people of all age ranges. In addition, all focus groups shared comments about transportation issues within West Bloomington. Regarding distressed amenities, focus group participants brought up issues concerning poor housing conditions, inadequate amenities at local parks, and old infrastructure in need of repair or replacement. Findings from key informant interviews also acknowledged several areas for enhancement within the West Bloomington community. Within the community, apathy and a lack of respect among residents were identified as negative attributes coupled with a perceived lack of police presence in the area. Residents linked these attributes to a fear of crime, and specifically, drug dealing, prostitution, and gang activity and recruitment. Resource collaboration and greater awareness of available resources also are viewed as necessary enhancements within the community and those serving it. West Bloomington residents serving as key informant interviewees identified issues of homelessness, overcrowded housing facilities, and a lack of affordable housing. Some interviewees expressed a desire for better notification of neighborhood events. Several interviewees mentioned a desire for better communication between the City of Bloomington and West Bloomington community and a better working relationship with the police department. Additionally, multiple interviewees discussed the importance of education, including the need for more job training and literacy programs. This report includes conclusions and recommendations based on findings from key informant interviews, focus groups, local and public data review, and past and future surveys. These recommendations are broken down into three categories focusing on the City of Bloomington, the West Bloomington neighborhood, and youth. City-related recommendations include the following: The Bloomington Police Department can increase its visible presence in the West Bloomington neighborhood by providing foot patrol. The City of Bloomington should develop a plan for addressing infrastructure needs in the West Bloomington area. The Bloomington-Normal Public Transit System can evaluate the current mass transit bus routes for West Bloomington. Improved civic awareness and education can increase residents‟ skills and abilities to address grievances and development issues within their community. Neighborhood recommendations advise the following: Primarily, communication among all stakeholders needs to be improved. Stakeholders can increase awareness of available services, programs, and resources that can benefit community members. A community fair can be held within the West Bloomington neighborhood. A feasibility study should be performed for a multi-purpose community center to be located in the West Bloomington neighborhood. The youth recommendations suggest the following: Encourage The Bloomington Boys and Girls Club to determine if additional services could be added to benefit the teen youth of West Bloomington. Increase the availability of summer programs to benefit both working parents and children. Explore effective strategies for identifying and dealing with barriers to development, especially those that apply to youth and crime. Stakeholders can collaborate on a campaign to bring awareness and encourage action around the need for more volunteer mentors, especially male mentors who are needed for West Bloomington male youth. In conclusion, this report sheds some light on the needs, wants, assets, and resources of the West Bloomington community. It is our hope that this report will serve as an impetus for enhanced relationships among the AAFW, the WBRP, West Bloomington residents, and the City of Bloomington, as well as provide information and materials to aid in future development

Individual based model links thermodynamics, chemical speciation and environmental conditions to microbial growth

Individual based Models (IbM) must transition from research tools to engineering tools. To make the transition we must aspire to develop large, three dimensional and physically and biologically credible models. Biological credibility can be promoted by grounding, as far as possible, the biology in thermodynamics. Thermodynamic principles are known to have predictive power in microbial ecology. However, this in turn requires a model that incorporates pH and chemical speciation. Physical credibility implies plausible mechanics and a connection with the wider environment. Here, we propose a step toward that ideal by presenting an individual based model connecting thermodynamics, pH and chemical speciation and environmental conditions to microbial growth for 5·105 individuals. We have showcased the model in two scenarios: a two functional group nitrification model and a three functional group anaerobic community. In the former, pH and connection to the environment had an important effect on the outcomes simulated. Whilst in the latter pH was less important but the spatial arrangements and community productivity (that is, methane production) were highly dependent on thermodynamic and reactor coupling. We conclude that if IbM are to attain their potential as tools to evaluate the emergent properties of engineered biological systems it will be necessary to combine the chemical, physical, mechanical and biological along the lines we have proposed. We have still fallen short of our ideals because we cannot (yet) calculate specific uptake rates and must develop the capacity for longer runs in larger models. However, we believe such advances are attainable. Ideally in a common, fast and modular platform. For future innovations in IbM will only be of use if they can be coupled with all the previous advances

PrEP use and unmet PrEP-need among men who have sex with men in London prior to the implementation of a national PrEP programme, a cross-sectional study from June to August 2019

BACKGROUND: Access to prevention options, including HIV pre-exposure prophylaxis (PrEP), remains a public health priority for gay, bisexual, and other men who have sex with men (MSM), especially in London. We describe PrEP use in a London community sample of MSM before the introduction of a national PrEP programme in October 2020. METHODS: From June-August 2019, MSM aged ≥ 18 recruited from London commercial venues were asked to self-complete a sexual health questionnaire and provide an oral fluid sample for anonymous HIV antibody testing. Descriptive analyses of demographic characteristics, service engagement and outcomes, as well as sexual risk and prevention behaviours were examined in the survey population and in those reporting current PrEP use. We performed sequential, multivariate analyses examining current PrEP use in MSM of self-perceived HIV-negative/unknown status with identified PrEP-need defined as the report of condomless anal sex (CAS) in the last three months, or the report of CAS (in the last year) with an HIV-positive/unknown status partner not known to be on HIV treatment, in reflection of UK PrEP guidelines. RESULTS: One thousand five hundred and thirty-fifth questionnaires were completed across 34 venues, where 1408 were analysed. One in five MSM of self-perceived HIV-negative/unknown status reported current PrEP use (19.7%, 242/1230). In men with PrEP-need, 68.2% (431/632) did not report current use. Current PrEP use was associated with age (aOR: 3.52, 95% CI: 1.76-7.02 in men aged 40-44 vs men aged 18-25) and education (aOR: 1.72, 95% CI: 1.01-2.92 in men with ≥ 2 years/still full-time vs no/ < 2 years of education since age 16). CONCLUSION: Among MSM in London, PrEP use is high but there is indication of unmet PrEP-need in men of younger age and lower levels of post-16 education. National programme monitoring and evaluation will require continued community monitoring to guide interventions ensuring equitable PrEP access and uptake in those who could most benefit from PrEP

Evaluating Cumulative Ecosystem Response to Restoration Projects in the Lower Columbia River and Estuary, 2009

This is the sixth annual report of a seven-year project (2004 through 2010) to evaluate the cumulative effects of habitat restoration actions in the lower Columbia River and estuary (LCRE). The project, called the Cumulative Effects Study, is being conducted for the U.S. Army Corps of Engineers Portland District (USACE) by the Marine Sciences Laboratory of the Pacific Northwest National Laboratory (PNNL), the Pt. Adams Biological Field Station of the National Marine Fisheries Service (NMFS), the Columbia River Estuary Study Taskforce (CREST), and the University of Washington. The goal of the Cumulative Effects Study is to develop a methodology to evaluate the cumulative effects of multiple habitat restoration projects intended to benefit ecosystems supporting juvenile salmonids in the 235-km-long LCRE. Literature review in 2004 revealed no existing methods for such an evaluation and suggested that cumulative effects could be additive or synergistic. From 2005 through 2009, annual field research involved intensive, comparative studies paired by habitat type (tidal swamp versus marsh), trajectory (restoration versus reference site), and restoration action (tidegate replacement vs. culvert replacement vs. dike breach)
