Published: August 2018

Black men, underrepresented in engineering, constitute a missing segment of the population who could contribute to the global knowledge economy. To address this national concern, stakeholders need additional research on strategies that aid in Black men’s persistence. This study explores the experiences of 30 Black men in engineering graduate programs. Three factors are identified as helping them persist from year to year, and in many cases through completion of the doctorate: the role of family, spirituality and faith-based community, and undergraduate mentors. The article concludes with implications for future research and professional practice that may improve the experiences of Black men in engineering graduate programs, which may also increase the chances that they will remain in the engineering workforce.

Published: August 2018

Non-invasive neuroimaging methods, including magnetoencephalography and electroencephalography (MEEG), have been critical in advancing the understanding of brain function in healthy people and in individuals with neurological or psychiatric disorders. Currently, scientific practice is undergoing a tremendous change, aiming to improve both research reproducibility and transparency in data collection, documentation and analysis, and in manuscript review. To advance the practice of open science, the Organization for Human Brain Mapping created the Committee on Best Practice in Data Analysis and Sharing (COBIDAS), which produced a report for MRI-based data in 2016. This effort continues with the OHBM’s COBIDAS MEEG committee whose task was to create a similar document that describes best practice recommendations for MEEG data. The document was drafted by OHBM experts in MEEG, with input from the world-wide brain imaging community, including OHBM members who volunteered to help with this effort, as well as Executive Committee members of the International Federation for Clinical Neurophysiology. This document outlines the principles of performing open and reproducible research in MEEG. Not all MEEG data practices are described in this document. Instead, we propose principles that we believe are current best practice for most recordings and common analyses. Furthermore, we suggest reporting guidelines for Authors that will enable others in the field to fully understand and potentially replicate any study. This document should be helpful to Authors, Reviewers of manuscripts, as well as Editors of neuroscience journals.

Wasted Evidence - An Assessment of the Prevalence and Determinants of Publication Bias in Africa
Authors: Kamande Mercyline
Published: August 2018

The quality and credibility of evidence influence how quickly findings are absorbed in policy. Publication bias threatens the validity of research synthesis by increasing the likelihood of false positives in individual studies, systematic reviews, and meta-analyses. Given that systematic reviews and meta-analyses are likely to influence policy decisions, complete reporting of research results and dissemination of research evidence are critical. This exploratory study investigated the rate of publication among African researchers, as well as the prevalence of publication bias and factors that contribute to it. The study sought to (i) establish the rate and determinants of research publication and (ii) test a methodology to quantitatively analyse publication bias using indices constructed with qualitative information relating to the publication process. Determinants of the rate of publication were found to be age, level of education, institutional affiliation, area of study and source of funding with level of education being the most important, followed by institutional affiliation and source of funding. PhD education level has the highest impact on the rate of publication with a marginal effect of 1.24 followed by area of study with a marginal effect of 1.14. The most important driver of significant results was the methodology index where the more sound the methodology, the more likely to obtain significant results. There was a positive effect of researcher perception on the probability of obtaining significant results and a negative effect of researcher quality on the same probability. Perception of the publication process, as well as poor methodology, are likely to increase the file drawer problem.

Environmental stewardship contributes more to the Massachusetts economy than whale watching, fin-fish fisheries
Authors: Open Communications for The Ocean OCTO
Published: August 2018

Commercial fishery interests and other extractive industries typically dominate discussions for environmental decision-making for the oceans and coasts. These industries can claim millions of dollars in benefits to local communities by simply adding up their sales. But there are lots of other coastal activities with less visible economic impacts. How can the economic benefits of marine stewardship and conservation activities be estimated? The authors used donations to coastal and marine civil society organizations, and volunteer efforts, to provide a conservative estimate of the economic benefits provided to the state.
UBC Excavations of the Roman Villa at Gerace, Sicily: Results of the 2016 Season
Authors: Wilson R.J.A. , Mukai Tomoo
Published: August 2018

A third season of excavation at the Roman rural estate of Gerace (Enna province, Sicily) took place in 2016. In the small late Roman villa of c. ad 370/375, the entire surviving length of the south corridor was uncovered for the first time; it is floored in polychrome geometric mosaic. Of particular interest is a mosaic “welcome mat” at the entrance, where a foot measuring-rod is depicted. The overall dimensions of the adjacent basilican storehouse, destroyed in the mid-fourth century before the construction of the late Roman villa, were established, and the use of the Greek Samian foot-unit in its design confirmed. Preliminary investigation of a kiln yielded bricks stamped with the name of Philippianus; others nearby record a separate name, Cn […] Cylin[drus]. In the northern part of the site, part of a well-preserved bath-house was excavated, including portions of two heated rooms and two adjacent hot-water pools. Its walls stand up to 2.30 m high; there were geometric mosaics on the floors and marble veneer on the walls. The date is uncertain (late fourth century?). On decommissioning, the baths were stripped of reusable material, including tubuli and the large bricks spanning the gaps between hypocaust pilae; to extract the latter the mosaic floors were smashed. Over 200 terracotta vaulting tubes used in roofing came from one of the pools. The end of the baths occurred sometime in the second half of the fifth century ad. Of the sixth- and seventh-century rural settlement which succeeded the élite structures, a portion of building with a paved yard and external staircase to an upper floor was also excavated.

Published: August 2018

Topicality. Market transformations in the country's economy caused the need to revise the labor relations institute from the economic development point of view. Particular importance was the theoretical reassessment labor relations institutional: the old labor law institutes, which corresponded to the administrative command system, must transform to new ones, that contain market needs. One of such labor relations institutes are contractual relations between the employer and the employee, which allow to personalize the labor relations as much as possible, consider the economic interest of both parties, and protect as far as possible the mutual interests and rights.

Aim and tasks. The aim of the article is represented the main tendencies and realities of using an employment contract in Ukraine's companies, which is signed in the standard form. The current legislation gaps of the contract using are considered as a special employment contract form with the companies leaders and other employees categories, depending on the specifics enterprise's activity or belonging to the management sphere. The preconditions for the special legislation implementation are determined during the labor contracts conclusion with the Ukrainian's nature reserve fund enterprises heads. The personal responsibility for environmental protection legislation and violation conditions are considered. Proactive and experienced specialists are established an extensive system of allowances and one-time incentives.

Research results. In this article we have reviewed the implementation preconditions during the labor contracts' conclusion with the enterprises' heads of the Ukrainian nature reserve fund. We have considered the responsibility personalization conditions for environmental legislation violations with the definition of socio-economic components. For example, the contract may also stipulate social and living conditions, such as the garden plot allocation, a car, living conditions improvement, the share sale at par value, the social pensions surcharges establishment, protection against inflation processes and so on. Also it may be envisaged an employee to move another area.

Conclusions. A contract can give the chance to more people to realize their work abilities on the most favorable conditions, to build the civil society foundations and the legal capitalist state. Contract's application can detail the labor relations, the system of economic incentives and encouragement, protects the rights of both employee and employer, and also provides an opportunity to assess the mutual responsibility's degree.

Research on fluid flow becomes a necessity toÂ develop technology and for the welfare of human beings on earth.Â One of them is study of fluid flow in the diffuser. The example ofÂ diffuser application is used as a flue gas duct in the car orÂ motorcycle. In addition, diffuser is also applied in airÂ conditioning systems. Diffuser is a construction that able to control the behavior of the fluid. The increasing of cross section area in the diffuser will generate a positive pressure gradient or also called adverse pressure gradient (APG). The greater APG that happens, the greater energy required by the fluid to fight it,Â because APG will lead to separation. This study aimed to evaluate the numerical fluid flow in the asymmetric diffuser withÂ divergence angle (Î¸) = 10 Â° (upper wall) and widening one vertical side (Î±) of 20 Â° (front wall). The Reynolds number is 8.7 xÂ 104 by high inlet diffuser and the maximum velocity at the inletÂ diffuser. Turbulence models used are standard k-É›, realizable k-Îµ,Â and shear stress transport (SST) k-Ï‰. Numerical study of steadyÂ RANS used Fluent 6.3.26 software. Results of numericalÂ visualizations show that huge vortex established in diffuser,Â thatâ€™s why performance of diffuser is not optimal. In addition theÂ location of separation point shown by SST k-Ï‰ is earlier thanÂ other turbulence models (standard k-Îµ and realizable k-Îµ).
