A Shifting Research Agenda: Historically Black Colleges and Universities Must Prepare Students for Careers in Computing, Informatics, and Engineering

This paper describes the founding principles upon which historically Black colleges and universities (HBCU) are built and examines their role in the high-tech economy. It examines and discusses the diversity issues that have led many to posit that HBCUs should embrace computing, informatics, and engineering as focal areas, and partner with Silicon Valley tech companies to ensure their graduates have the skills necessary for gainful employment. The Howard-West partnership of Howard University (an HBCU) with Google LLC and an enterprise architecture framework are presented as conceptual examples of how colleges and universities such as Howard University, can work together and with industry to introduce students to computing, regardless of major, to prepare them for the modern workforce. A conceptual framework is presented, guided by the outcomes of the social cognitive career theory. The theoretical orientation of this proposed work focuses on the intersection between individual, environmental, and behavioral attributes, and describes formative and summative evaluation criteria in support of the research and educational goals. HBCUs can be better served by prioritizing the very areas in which they are currently “overproducing” graduates—computing, informatics, and engineering. The proposed model can be adopted, modified, and integrated by HBCUs, and other universities and colleges, that suffer from a lack of disciplinary integration in their computing programs. The potential outcome of the work would be to attract and retain students to computing majors, which could have an impact on the technology workforce

Illuminating the Shadows: Unveiling the Path of Black Men in the Information Technology Workforce

The absence of Black1 men2 in the Information Technology (IT)3 sector is a pressing issue both in academia and society. Diversity enriches learning, with diverse backgrounds offering varied experiences. An ethnically varied IT field can significantly influence the recruitment and retention of minority undergraduates by offering mentors and role models. This research, rooted in the Individual Differences Theory of Gender and IT, uses qualitative methods and interviews to delve into the experiences of Black men. While many studies touch upon gender and racial disparities, few specifically address Black men's experiences. This paper bridges this gap, spotlighting the underrepresentation of Black men in IT, and identifies key factors for future research based on a study begun in 2011, further enriching existing literature and theories

The Underrepresentation of Black Males in IT Higher Education: a Conceptual Framework for Understanding Individual Differences

Among the many research challenges in studying underrepresented groups in IT is understanding the appropriate theories to apply and much needed analysis at the individual level. This paper presents findings of two studies, which coupled with the application of the Individual Differences Theory of Gender and IT, led to a conceptual framework being developed to delve deeper into the understanding of Black males in IT higher education. The use of the conceptual framework will lead to a better understanding of the factors impacting underrepresented groups participation in IT

Generation Z, Learning Preferences, and Technology: An Academic Technology Framework Based on Enterprise Architecture

This work provides an overview of Generation X, Y (Millennials), and Z and their characteristics in academia. We present the ways that mobile technology is infused into their lifestyle. We reference how Generation Y and Z in particular expect technology to be integrated into their educational experience, as well as how it helps faculty to facilitate both synchronous and asynchronous learning. Furthermore, an overview is provided of how technology currently contributes to learning and provides a framework for how educators can better engage current students. The conceptual academic technology framework (ATF) put forth in this work will provide an immediate impact in several key areas. This framework enhances structure during course design, which may be based directly on learning outcomes and department/school objectives. It will also directly improve consistency in faculty/student communication by closely monitoring how changes in communication methods have evolved. Finally, we describe how to integrate technology in a meaningful way, in a manner that does not distract students while preparing them for careers in business

A neural integrator model for planning and value-based decision making of a robotics assistant

Modern manufacturing and assembly environments are characterized by a high variability in the built process which challenges human–robot cooperation. To reduce the cognitive workload of the operator, the robot should not only be able to learn from experience but also to plan and decide autonomously. Here, we present an approach based on Dynamic Neural Fields that apply brain-like computations to endow a robot with these cognitive functions. A neural integrator is used to model the gradual accumulation of sensory and other evidence as time-varying persistent activity of neural populations. The decision to act is modeled by a competitive dynamics between neural populations linked to different motor behaviors. They receive the persistent activation pattern of the integrators as input. In the first experiment, a robot learns rapidly by observation the sequential order of object transfers between an assistant and an operator to subsequently substitute the assistant in the joint task. The results show that the robot is able to proactively plan the series of handovers in the correct order. In the second experiment, a mobile robot searches at two different workbenches for a specific object to deliver it to an operator. The object may appear at the two locations in a certain time period with independent probabilities unknown to the robot. The trial-by-trial decision under uncertainty is biased by the accumulated evidence of past successes and choices. The choice behavior over a longer period reveals that the robot achieves a high search efficiency in stationary as well as dynamic environments.The work received financial support from FCT through the PhD fellowships PD/BD/128183/2016 and SFRH/BD/124912/2016, the project “Neurofield” (PTDC/MAT-APL/31393/2017) and the research centre CMAT within the project UID/MAT/00013/2013

Earthworm invasion into previously earthworm-free temperate and boreal forests

Earthworms are keystone detritivores that can influence primary producers by changing seedbed conditions, soil characteristics, flow of water, nutrients and carbon, and plant–herbivore interactions. The invasion of European earthworms into previously earthworm-free temperate and boreal forests of North America dominated by Acer, Quercus, Betula, Pinus and Populus has provided ample opportunity to observe how earthworms engineer ecosystems. Impacts vary with soil parent material, land use history, and assemblage of invading earthworm species. Earthworms reduce the thickness of organic layers, increase the bulk density of soils and incorporate litter and humus materials into deeper horizons of the soil profile, thereby affecting the whole soil food web and the above ground plant community. Mixing of organic and mineral materials turns mor into mull humus which significantly changes the distribution and community composition of the soil microflora and seedbed conditions for vascular plants. In some forests earthworm invasion leads to reduced availability and increased leaching of N and P in soil horizons where most fine roots are concentrated. Earthworms can contribute to a forest decline syndrome, and forest herbs in the genera Aralia, Botrychium, Osmorhiza, Trillium, Uvularia, and Viola are reduced in abundance during earthworm invasion. The degree of plant recovery after invasion varies greatly among sites and depends on complex interactions with soil processes and herbivores. These changes are likely to alter competitive relationships among plant species, possibly facilitating invasion of exotic plant species such as Rhamnus cathartica into North American forests, leading to as yet unknown changes in successional trajectory

Effects of fluoxetine on functional outcomes after acute stroke (FOCUS): a pragmatic, double-blind, randomised, controlled trial

Background Results of small trials indicate that fluoxetine might improve functional outcomes after stroke. The FOCUS trial aimed to provide a precise estimate of these effects. Methods FOCUS was a pragmatic, multicentre, parallel group, double-blind, randomised, placebo-controlled trial done at 103 hospitals in the UK. Patients were eligible if they were aged 18 years or older, had a clinical stroke diagnosis, were enrolled and randomly assigned between 2 days and 15 days after onset, and had focal neurological deficits. Patients were randomly allocated fluoxetine 20 mg or matching placebo orally once daily for 6 months via a web-based system by use of a minimisation algorithm. The primary outcome was functional status, measured with the modified Rankin Scale (mRS), at 6 months. Patients, carers, health-care staff, and the trial team were masked to treatment allocation. Functional status was assessed at 6 months and 12 months after randomisation. Patients were analysed according to their treatment allocation. This trial is registered with the ISRCTN registry, number ISRCTN83290762. Findings Between Sept 10, 2012, and March 31, 2017, 3127 patients were recruited. 1564 patients were allocated fluoxetine and 1563 allocated placebo. mRS data at 6 months were available for 1553 (99·3%) patients in each treatment group. The distribution across mRS categories at 6 months was similar in the fluoxetine and placebo groups (common odds ratio adjusted for minimisation variables 0·951 [95% CI 0·839–1·079]; p=0·439). Patients allocated fluoxetine were less likely than those allocated placebo to develop new depression by 6 months (210 [13·43%] patients vs 269 [17·21%]; difference 3·78% [95% CI 1·26–6·30]; p=0·0033), but they had more bone fractures (45 [2·88%] vs 23 [1·47%]; difference 1·41% [95% CI 0·38–2·43]; p=0·0070). There were no significant differences in any other event at 6 or 12 months. Interpretation Fluoxetine 20 mg given daily for 6 months after acute stroke does not seem to improve functional outcomes. Although the treatment reduced the occurrence of depression, it increased the frequency of bone fractures. These results do not support the routine use of fluoxetine either for the prevention of post-stroke depression or to promote recovery of function.

Effectiveness of a national quality improvement programme to improve survival after emergency abdominal surgery (EPOCH): a stepped-wedge cluster-randomised trial

BACKGROUND: Emergency abdominal surgery is associated with poor patient outcomes. We studied the effectiveness of a national quality improvement (QI) programme to implement a care pathway to improve survival for these patients. METHODS: We did a stepped-wedge cluster-randomised trial of patients aged 40 years or older undergoing emergency open major abdominal surgery. Eligible UK National Health Service (NHS) hospitals (those that had an emergency general surgical service, a substantial volume of emergency abdominal surgery cases, and contributed data to the National Emergency Laparotomy Audit) were organised into 15 geographical clusters and commenced the QI programme in a random order, based on a computer-generated random sequence, over an 85-week period with one geographical cluster commencing the intervention every 5 weeks from the second to the 16th time period. Patients were masked to the study group, but it was not possible to mask hospital staff or investigators. The primary outcome measure was mortality within 90 days of surgery. Analyses were done on an intention-to-treat basis. This study is registered with the ISRCTN registry, number ISRCTN80682973. FINDINGS: Treatment took place between March 3, 2014, and Oct 19, 2015. 22 754 patients were assessed for elegibility. Of 15 873 eligible patients from 93 NHS hospitals, primary outcome data were analysed for 8482 patients in the usual care group and 7374 in the QI group. Eight patients in the usual care group and nine patients in the QI group were not included in the analysis because of missing primary outcome data. The primary outcome of 90-day mortality occurred in 1210 (16%) patients in the QI group compared with 1393 (16%) patients in the usual care group (HR 1·11, 0·96-1·28). INTERPRETATION: No survival benefit was observed from this QI programme to implement a care pathway for patients undergoing emergency abdominal surgery. Future QI programmes should ensure that teams have both the time and resources needed to improve patient care.

Research Implications of the Tech Exchange: Immersion of Howard University Computer Science and Informatics Students in Silicon Valley

In this paper, we begin the process of designing a study which will study the implications of Howard University’s Tech Exchange program where students are embedded in Silicon Valley taking courses at Google instead of their home campus in Washington, D.C. Given the partnership aimed at increasing diversity in Silicon Valley, it is worth exploring mechanisms by which this strategy can be assessed in terms of benefits not only to Google and Howard University, but also the student and their identity development and self-efficacy in informatics
