You Do Belong! Transformative Black Women Faculty Recommendations for Broadening Participation in US P-20 Computing Education

&#x0D; This study aimed to amplify Black women faculty’s recommendations for broadening participation of the next generation of Black girls and women as they matriculate from primary school into advanced graduate degrees (P-20) in computing education (CE). As tenure-track faculty, these transformative women have attained the highest degree (i.e., Ph.D.) in postsecondary CE in the United States (US). To govern the knowledge validation process, I utilized Afrocentric feminist epistemology undergirded by critical race theory and Black feminist thought. Upon conducting thematic analysis, I identified four emergent themes to broaden participation of Black girls and women in computing: 1) improve access, quality, and early exposure to CE, 2) create equitable and equal spaces for Black girls and women, 3) confront unconscious biases of teachers and faculty, and 4) provide mentoring opportunities. As an emerging Black woman scholar, with a bachelor’s degree in computer science and 15 years of industry experience, I had a “unique angle of vision” to interpret and inform this study’s findings. This study builds upon limited knowledge about interventions needed to support Black girls and women in US P-20 computing education.

Mining Design Heuristics for Additive Manufacturing Via Eye-Tracking Methods and Hidden Markov Modeling

Abstract In this research, we collected eye-tracking data from nine engineering graduate students as they redesigned a traditionally manufactured part for additive manufacturing (AM). Final artifacts were assessed for manufacturability and quality of final design, and design behaviors were captured via the eye-tracking data. Statistical analysis of design behavior duration shows that participants with more than 3 years of industry experience spend significantly less time removing material and revising than those with less experience. Hidden Markov modeling (HMM) analysis of the design behaviors gives insight to the transitions between behaviors through which designers proceed. Findings show that high-performing designers proceeded through four behavioral states, smoothly transitioning between states. In contrast, low-performing designers roughly transitioned between states, with moderate transition probabilities back and forth between multiple states.

UX in Industry: An ‘Unconference’ w/ the Practitioners

UX roles in industry come in various flavors. From job titles, roles and responsibilities to organizational structure, companies define user experience practitioners in varying ways. The purpose of this alternative session is to give students a diverse look at UX in Industry. Seattle and the Pacific Northwest are home to several major technology companies such as Amazon, Microsoft, Google, and Intel. This alt session will utilize the unconference format. This will allow facilitators to lead small group discussions based on topics posed by the session attendees. The group of facilitators will consist of a diverse collective of UX researchers and designers from various companies with varying degrees of formal education. Conference attendees will be asked to submit questions via Twitter and at the beginning of the session. Following introductions, the session attendees will be broken into 5 smaller groups. The industry practitioners will serve as discussion facilitators leading the conversation around the submitted topics. It is the intent that they will be able to discussed topics such as what “UX looks like” at their respective companies and the best approach a student can take to prepare now to be successful at their company, but ultimately the topics will come from the attendees. The five panelists have several years of industry experience and have worked for multiple companies; therefore, they can bring perspective from a myriad of experiences.

The normative beliefs that form individual food safety behavioral intention: A qualitative explanatory study

Reports from the Center for Control Disease and Prevention suggest that approximately 61% of foodborne illnesses were attributed to improper food handling and is the leading cause of outbreaks in the foodservice industry. However, even when employees are trained in food safety, knowledge does not translate into improved practices on the job. Several meta-analyses have suggested the importance of using injunctive norms to predict individual behavior in both social psychology and management journals. Therefore, the purpose of this study is to identify and explore the normative beliefs related to predicting employees’ food safety behavioral intentions.An online survey was first distributed to foodservice employees to measure individual-level norms about food safety practices. A follow-up qualitative questionnaire helped generate an in-depth understanding of employees’ experiences. The narrative texts were then analyzed using ATLAS.ti. Additional diagram analyses were conducted.A total of 104 responses were documented with mostly female participants, a mean age of 36, and an average of about 11.2 years of industry experience. The results indicated that employees were usually not influenced by their manager or coworkers’ approval. Instead, their behavior was guided by innate motivations of moral reasoning and personal ethics. The data further noted that intrinsic motivation should be an essential construct to form normative beliefs. The results challenge the previous understanding regarding normative pressure in food safety. Revalidation of the theory and path inference directions are discussed.

Use of Surfactants in Manufacture of Catalysts for Conversion of Methane

Effects are compared of various surfactants on the properties of an impregnating solution of nickel and aluminum nitrates in the condensate, used in manufacture of supported catalysts for conversion of methane. It was shown that use of synthanols (oxyethylated alcohols, which are nonionogenic surfactants) makes it possible to significantly (by three orders of magnitude) reduce the necessary content of surfactants in solution, which is confirmed by many years of industrial experience. Results are presented of quantum-chemical calculations of the interaction of synthanol molecules with nickel ions. The use of synthanol can substantially reduce the probability of carbonization of the catalyst surface and the possible carryover of a part of metal ions with the impregnating solution and also diminish the toxicity and the explosion hazard in the production area.

Comparison of Agile Method and Scrum Method with Software Quality Affecting Factors

The software industry used software development lifecycle (SDLC) to design, develop, produce high quality, reliable and cost-effective software products. To develop an application, project team used some methodology which may include artifacts and pre-defining specific deliverables. There are different SDLC process models such as waterfall, iterative, spiral and agile model available to develop a quality product. In this paper we focus only on agile software development model, and Scrum model and their techniques. There are many papers and books written on agile methodologies. We will also use their knowledge in this paper. To collect data for comparison of agile method with software quality affecting factors, an online questionnaire survey was conducted. The survey sample consisted of software developers with several years of industry experience using agile methodologies. The main purpose of this study is to compare soft-ware quality affecting factors with agile and scrum model.

Significance of race in the US undergraduate public relations educational landscape

Purpose The purpose of this study is to address a practical question and problem: what can explain the small number of underrepresented racial and ethnic practitioners in the public relations industry? By placing race at the center of this study via critical race theory, the authors sought to answer the previously mentioned practical question. The authors focused on the undergraduate environment as a pipeline to the profession. The goal was to determine whether issues of race in the undergraduate public relations environment played a role in students’ ability to succeed in their public relations coursework and in their ability to secure internships, network with professionals, etc. Design/methodology/approach The authors interviewed 22 practitioners with five or fewer years of industry experience. The authors used email interviews to gather data from young professionals. Although email interviews are impersonal in nature, because of a lack of the use of social cues and non-verbal communication (Hunt &amp; McHale, 2007), email interviews are more cost-effective, expand the range of participants that one could interview, and this method allows participants to reflect longer on their answers, which could result in more detail – whereby participants might share information they would not normally share face-to-face. Findings The findings reveal that half of the Latina, African American and Asian American participants noted that being underrepresented was not necessarily a hindrance to their academic success; rather, being underrepresented was uncomfortable for them at times, as they believed they had to prove themselves more than whites. Additional findings reveal that in terms of developing social skills for the profession, participants did not experience negative or positive effects of race. Findings are used to gain insight into how to increase diversity in the profession and to gauge the extent to which racial identity plays a role in public relations students’ collegiate development. Originality/value This study asks racially and ethnically underrepresented applied communication students to reflect on their experiences as undergraduates as a means of refining the undergraduate educational experience to make that experience more attractive for and conducive to academic success for current and future underrepresented applied communication undergraduate students. It's a first of its kind in that regard.

A Comprehensive Approach to Dynamic Project Risk Management

A large percentage of projects suffer performance, cost, and/or schedule problems. There are many reasons why projects fail, including an inadequate approach to risk management. Inadequate approaches result when a comprehensive identification of risks is not performed at project commencement, when risk assessment fails to consider important aspects, when no subsequent follow-up is carried out for mitigation strategies adopted, when no further identification of risks during project execution is completed, or a combination of these occurs. A number of publications have dealt with different facets of risk management, but not in a comprehensive way. This article compiles the approaches applied and observed by the author based on 25 years of industry experience; these observations were synthesized and result in a procedure for dynamic risk management successfully applied to a number of projects. The use of a broad array of techniques is suggested to identify risks, which are then thoroughly analyzed. The assessment was performed using a comprehensive array of criteria. The complete set of criteria included essential ones such as aggregability factor, triggering factor, early warning, immediacy, and recoverability. The thorough assessment was done dynamically. The initial assessment enables the adoption of the most adequate mitigation strategies, which later on are dynamically validated. New risks are also detected and dealt with dynamically throughout project execution. The main contribution of this work is the synthesis of state-of-the-art knowledge into a state-of-the-practice procedure, which can be applied by engineering managers in all sectors and in all phases of project execution.

Engineering educators’ perceptions of the influence of professional/industry experience on their teaching practice

Abstract –This preliminary study explored engineering educators’ perceptions of the influence of industry experience on their teaching practice. Fifty American engineering educators were interviewed. There appeared to be a distinction in the extent to which influence on practice was reported, based on years of industry experience. Three themes emerged – influence on content and curriculum, influence on instructional strategies and the integration of real world components, and benefits of being a practitioner/educator. Implications and future research are discussed.

The Safety Pharmacology Society salary survey

IntroductionSafety pharmacology is a growing discipline with scientists broadly distributed across international geographical regions. This electronic salary survey is the first to be distributed amongst the entire Safety Pharmacology Society (SPS) membership. An electronic survey was sent to all members of the Society. Categorical survey questions assessed membership employment types, annual incomes, and professional certifications, along with other associated career attributes. MethodsThis survey was distributed to the SPS membership that is comprised of safety pharmacologists, toxicologists and pharmacologists working globally in the pharmaceutical industry, at contract research organizations (CRO), regulatory agencies, and academia or within the technology provider industry. The survey was open for responses from December 2015 to March 2016. ResultsThe survey response rate was 28% (129/453). North America (68%) was the region with the largest number of respondents followed by Europe (28%). A preponderance of respondents (77%) had 12years of industry experience or more. 52% of responders earned annually between $40,000 and $120,000. As expected, salary was generally positively correlated with the number of years of experience in the industry or the educational background but there was no correlation between salary and the number of employee's directly supervised. The median salary was higher for male vs female respondents, but so was median age, indicative of no gender ‘salary gap’. DiscussionOur 2016 SPS salary survey results showcased significant diversity regarding factors that can influence salary compensation within this discipline. These data provided insights into the complex global job market trends. They also revealed the level of scientific specialization embedded within the organization, presently uniquely positioned to support the dynamic career paths of current and future safety pharmacologists.

Expert opinion on risks to the long-term viability of residential recycled water schemes: An Australian study

The water sector needs to make efficient and prudent investment decisions by carefully considering the long-term viability of water infrastructure projects. To support the assessment and planning of residential recycled water schemes in Australia, we have sought to clarify scheme objectives and to further define the array of critical risks that can impact the long-term viability of schemes. Building on historical information, we conducted a national survey which elicited responses from 88 Australian expert practitioners, of which 64% have over 10 years of industry experience and 42% have experience with more than five residential recycled water schemes. On the basis of expert opinion, residential recycled water schemes are considered to be highly relevant for diversifying and improving water supply security, reducing wastewater effluent discharge and pollutant load to waterways and contributing to sustainable urban development. At present however, the inability to demonstrate an incontestable business case is posing a significant risk to the long-term viability of residential recycled water schemes. Political, regulatory, organisational and financial factors were also rated as critical risks, in addition to community risk perception and fall in demand. The survey results shed further light on the regulatory environment of residential recycled water schemes, with regulatory participants rating the level and impact of risk factors higher than other survey participants in most cases. The research outcomes provide a comprehensive understanding of the critical risks to the long-term viability of residential recycled water schemes, thereby enabling the specification of targeted risk management measures at the assessment and planning stage of a scheme.

Interview

Dr Niksa Tadic from the University of Montenegro talks to us about the work behind the paper ‘A 100 MHz current generator with T/(T-t) time waveform in 0.35 μm BiCMOS technology model’, page 744. Dr Niksa Tadic In 1995, after three years of industrial experience, I joined the University of Montenegro, Faculty of Electrical Engineering. I am interested in optoelectronic integrated circuit design including optical receivers with variable transimpedances, red-green-blue optical sensors, and current drivers for laser diodes in both CMOS and BiCMOS technologies. At the moment, together with my colleagues from the EMCE Institute in Vienna and the University of Montenegro in Podgorica, I am working on negative resistance based voltage amplifiers. The small-signal amplification approach based on the shifting of a DC operating point along the linear part of the voltage amplifier's transfer characteristic has become questionable in deep submicron technologies. The slope of the linear part of the amplifier's transfer characteristic reduces with the decrease of transistors dimensions, causing decrease of the voltage gain. The nonlinear small-signal amplification method based on negative resistance could be used as an alternative to the linear approach. I have reported in Electronics Letters a design of a current generator suitable for optical quantum random number generation (OQRNG), designed in 0.35 mm BiCMOS technology, with T/(T-t) time dependence. Logarithmic converter and differentiator used in an existing design have been avoided in the proposed design by using the BJT translinear loop. The achieved frequency bandwidth of the current pulses of 100 MHz is 5 times larger in comparison to the state-of-the-art, with at least 20 times smaller power consumption. The relative error of the measured waveform at 20 MHz is less than 3% in 97.5% of the time interval in which the current pulses have a rising slope. A generator based on a random physical phenomenon is the only method to obtain true random numbers. OQRNG based on the randomness of detecting single photons is of special interest because of its fast generation of random numbers and reliability. Hence, the proposed current generator with T/(T-t) time dependence can be applied in all those fields where true random numbers are needed, such as cryptography, statistical analysis, numerical simulations, or lottery games. In addition to the mentioned negative resistance based voltage amplifiers, I am working on further improvement of the OQRNG based on the proposed current generator with T/(T-t) time dependence. During the last 12 years of my research in optoelectronics, among the other specific applications in the field, there have been efforts toward research and development of optical detectors of various types (especially photodiodes), optical receivers with variable transimpedances intended for the universal optical storage systems (CD, DVD, Blu-Ray), colour sensors, and optical distance measurement systems. In the future, without any doubt, one of the main research interests in the field of optoelectronics will be the systems for detection of weak optical signals based on single photon avalanche diodes (SPADs). When a single photon is absorbed in the space-charge region of the SPAD, an electron-hole pair is generated. Due to the high electric field, additional electron-hole pairs are generated causing the rapid rise of the avalanche current. The avalanche current must be quenched to allow the detection of the next photon. To provide data transfer based on weak optical signals in the GHz region, the quenching of the avalanche current should be performed very fast, typically within 1 ns. This task is a great challenge for researchers in this area.

Use of waste derived fuels in cement industry: a review

Purpose – Cement production has advanced greatly in the last few decades. The traditional fuels used in traditional kilns include coal, oil, petroleum coke, and natural gas. Energy costs and environmental concerns have encouraged cement companies worldwide to evaluate to what extent conventional fuels can be replaced by waste materials, such as waste oils, mixtures of non-recycled plastics and paper, used tires, biomass wastes, and even wastewater sludge. The paper aims to discuss these issues. Design/methodology/approach – The work is based on literature review. Findings – The clinker firing process is well suited for various alternative fuels (AF); the goal is to optimize process control and alternative fuel consumption while maintaining clinker product quality. The potential is enormous since the global cement industry produces about 3.5 billion tons that consume nearly 350 million tons of coal-equivalent fossil and AF. This study has shown that several cement plants have replaced part of the fossil fuel used by AF, such waste recovered fuels. Many years of industrial experience have shown that the use of wastes as AF by cement plants is both ecologically and economically justified. Originality/value – The substitution of fossil fuels by AF in the production of cement clinker is of great importance both for cement producers and for society because it conserves fossil fuel reserves and, in the case of biogenic wastes, reduces greenhouse gas emissions. In addition, the use of AF can help to reduce the costs of cement production.
