Abstract:
A review of: Duy, Joanna and Liwen Vaughan. “Can Electronic Journal Usage Data Replace Citation Data as a Measure of Journal Use? An Empirical Examination.” The Journal of Academic Librarianship 32.5 (Sept. 2006): 512-17. Abstract Objective – To identify valid measures of journal usage by comparing citation data with print and electronic journal use data. Design – Bibliometric study. Setting – Large academic library in Canada. Subjects – Instances of use were collected from 11 print journals of the American Chemical Society (ACS), 9 print journals of the Royal Society of Chemistry (RSC), and electronic journals in chemistry and biochemistry from four publishers – ACS, RSC, Elsevier, and Wiley. ACS, Elsevier, and Wiley journals in chemistry-related subject areas were sampled for Journal Impact Factors and citations data from the Institute for Scientific Information (ISI). Methods – Journal usage data were collected to determine if an association existed between: (1) print and electronic journal use; (2) electronic journal use and citations to journals by authors from the university; and (3) electronic journal use and Journal Impact Factors. Between June 2000 and September 2003, library staff recorded the re-shelving of bound volumes and loose issues of 20 journal titles published by the ACS and the RSC. Electronic journal usage data were collected for journals published by ACS, RSC, Elsevier, and Wiley within the ISI-defined chemistry and biochemistry subject area. Data were drawn from the publishers’ Level 1 COUNTER compliant usage statistics. These data equate 1 instance of use with a user viewing an HTML or PDF full text article. The period of data collection varied, but at least 2.5 years of data were collected for each publisher. Journal Impact Factors were collected for all ISI chemistry-related journals published by ACS, Elsevier, and Wiley for the year 2001. Library Journal Utilization Reports (purchased from ISI) were used to determine the number of times researchers at the university cited journals in the same set of chemistry-related journals over the period 1998 to 2002. The authors call this “local citation data.” (512) The results from electronic journal use were also analysed for correlation with the total number of citations, as reported in the Journal Citation Reports, for each journal in the sample. Main results – The study found a significant correlation between the results for print journal and electronic journal usage. A similar finding was reported for correlation between electronic journal usage data and local citation data. No significant association was found between Journal Impact Factors and electronic journal usage data. However, when an analysis was conducted for the total number of citations to the journals (drawn from the Journal Impact Factor calculations in Journal Citation Reports) and electronic journal use, significant correlations were found for all publishers’ journals. Conclusion – Within the fields of chemistry and biochemistry, electronic journal usage data provided by publishers are an equally valid method of determining journal usage as print journal re-shelving data. The results of the study indicate this association is valid even when print journal subscriptions have ceased. Local citation data (the citations made by researchers at the institution being studied) also provide a valid measure of journal use when compared with electronic journal usage results. Journal Impact Factors should be used with caution when libraries are making journal collection decisions.

La pensée de Françoise s’y articule autour de deux axes majeurs pendant les sept années de sa parution. Elle milite en faveur de l’émancipation des femmes et de leur droit à prendre une place à part entière dans la société. En même temps, elle défend la liberté de pensée et d’expression. Ses prises de position, qui ne vont pas sans susciter des conflits avec Mgr Paul Bruchési, archevêque de Montréal, révèlent son audace et sa modernité.

Abstract:
Under slutet av 1800-talet publicerades tidningen Svenska familj-journalen i flera årgångar som en tidning menad att läsas av hela familjen som underhållning. Ett inslag i tidningen var berättelser om främmande länder och folkslag. Skribenterna beskrev en exotisk och sensationell värld utanför Sverige i sina artiklar och för många i läsarkretsen var detta deras enda kontakt med omvärlden. På ett sätt kan man säga att världen hälsade på hos läsarna istället för tvärtom. Det är dessa artiklar om andra nationaliteter jag har undersökt i min kandidatuppsats. Undersökningen granskar artiklar som innehåller framställningar av främmande folkslag utanför och inom Europa samt samer. Studien baseras på Saids teori om Orientalism och Foucaults diskursteori samt tidgare forskning kring svensk identitet och rasrepresentationer. Syftet med undersökningen är att granska den svenska självbilden under slutet av 1800-talet genom att undersöka rasrepresentationer i tidningen Svenska familj-journalen under åren 1864-1881. Min undersökning demonstrerar att den svenska självbilden genomgick förändring och dessutom var relativt splittrad under 1800-talet.

Abstract:
This study explored the separation of twins in foster care and examined how their lived experiences relate to their interpersonal relationships as adults. Many researchers have studied the long-term impact of nontwin sibling separation in foster care, but little is known about the separation of twins, leaving a significant gap in existing literature. The purpose of this study was to examine the lived experiences twins who were separated in foster care as relates to their interpersonal relationships during adulthood. A qualitative, narrative approach was used to gather the lived experiences of one set of twins. The research questions examined how one specific set of adult fraternal twin sisters interpreted their personal experiences of being separated from each other while in foster care and whether this experience had an impact on their interpersonal relationships. The study relied on the theoretical foundations of attachment theory and family systems theory to support the use of existing literature and to integrate the research findings into current child welfare practice. Through personal interviews, each twin was asked to recall experiences from foster care and comment on the impact of being separated from their twin. Thematic analysis of the interview data and observations of the interview process helped to identify four themes: forming successful attachments, mental health issues, trauma history, and number and type of placements experienced. To encourage social change these results can inform the child welfare system, add to the body of existing research, and influence future placement decisions regarding twins in foster care.

Cette étude de la presse en Ontario français cherche à revenir sur le débat quant à rupture du Canada français et sur l’immense fragmentation identitaire qui se serait opérée dans les communautés francophones du pays en analysant les prises de position de journaux régionaux. La thèse relève d’importants vestiges du Canada français dans la mise en sens par les journaux des revendications franco-ontariennes, notamment en ce qui a trait à la question scolaire, aux langues officielles et au statut des minorités francophones du pays. Elle effectue aussi une tâche inédite jusqu’à présent : mettre en relation cinq hebdomadaires et un quotidien afin de mieux saisir la complexité idéologique qui caractérise le débat public franco-ontarien. L’étude montre aussi l’existence d’un comportement « nationalitaire » dans la presse qui, nourrie de la mémoire du Canada français, sert de pierre angulaire pour les revendications des Franco-Ontariens.

Abstract:
Jag har ägnat denna uppsats åt att undersöka Kungliga Konstakademiens elevtidning Palettskrap från och med att det grundades 1877 till och med 1904.Tidningen består av anteckningar, protokoll och en mängd med bilder såsom porträtt, illustrationer och skämtteckningar. Mitt syfte har varit att se hur konflikten kring kvinnorollen generellt och kvinnliga konstnärsrollen specifikt kommer till uttryck under det sena 1800-talet i en intern elevtidning som Palettskrap. Jag har huvudsakligen utfört bildanalyser men även lyft fram text ur Palettskrap som har varit relevant för mitt ämne. Jag har analyserat bildernas uttryck och bildbudskap utifrån Roland Barthes semiotiska metod. För en genusmedveten och kritisk blick på det konsthistoriska sammanhanget, har jag har tillämpat ett feministiskt perspektiv som varit verktyg för att dekonstruera den maskulina myten om modernismen och konstnären. Min undersökning visar att det finns två etablerade stereotyper/kategorier av den kvinnliga konstnären: den ”okvinnliga” konstnären och ”amatören”. Dessa två stereotyper återspeglar den borgerliga synen på kvinnlighet/femininitet som oförenlig med konstnärsrollen.
I have dedicated this essay in researching the journal Palettskrap founded by students at the Royal Swedish Academy of Arts in 1877. Palettskrap consists of notes, protocols and a variety of images such as portraits, illustrations and satirical cartoons. My purpose has specifically been to see how the conflict of the woman artist is articulated during the late 1800's in a student journal such as Palettskrap, and also more generally, how the woman's role in society is articulated. I have primarily analyzed images but I have also exposed text from Palettskrap which has been relevant to my subject matter. By using Roland Barthes' semiotics, I have analyzed the images' expression and message. For a gender-sensitive and critical eye on the art historical context, I have applied feminist theory which has been useful in deconstructing the masculine myth on modernism and ”the artist”. My research shows that there are two established stereotypes/categories of the woman artist: the ”unwomanly” artist and the ”amateur”. These two stereotypes reflect the bourgeois notions of womanhood/femininity as incompatible with the role of the artist.

A procedure is during recent decades, the explosive development of the information technology has brought a remarkable advance in search engine and it has also changed our daily life. Nowadays, most information retrieval (IR) systems can only help us search information with simple interface, but the IR system that can help integrate web browsing and searching functions is very rare. Fortunately, Concept Lattice can help address the shortage and provide the browse of web tree structure. This paper uses Formal Concept Analysis (FCA) to construct Chinese Information Retrieval, and provides a browsing and searching system in Chinese data. This system can display multi-browsing modes for Concept Lattice, and we use both bottom-up (from the Infimum to the Supremum) and top-down (from the Supremum to the Infimum) searching way to help users find information efficiently and correctly. We also use tree structure and similarity order to present our result. To evaluate the searching quality and performance, this paper uses the data form Journal of Information Management as our data set.

AbstractReuters News Agency started the idea of ranking the World’s Most Innovative Universities. It relied on data compiled by Clarivate Analytics and several of its research platforms [25]. The latter company used to be called “Intellectual Property and Science Business of Thomson Reuters.” The process began by identifying approximately 600 academic and government organizations that published the greatest number of articles in scholarly journals. Reuters, then, put ten criteria for the innovation to evaluate the chosen organizations. These criteria are presented later in Sect. 2.3.

Abstract:
Do the changes in the scientific article incident on Internet publication constitute a revolution in representation and communication? John Stewart MacKenzie Owen insists that they do not. In The Scientific Article in the Age of Digitization, he argues that contrary to claims about the impact of digitization on scientific communication, “the journal article as a communicative form for reporting on research and disseminating scientific knowledge does not seem to have been transformed by … [the Internet]: it remains a digital copy of the printed form.” Owen views the current situation as preserving and extending “existing functions and values rather than as an innovation that radically transforms a communicative practice that has evolved over the centuries.” The conclusion Owen draws cannot be faulted. We do not doubt that the articles and journals in his sample are, on average, to quote Stevan Harnad, “mere clones of paper journals, ghosts in another medium.” We do, however, question Owen’s sample of online scientific journals. While he includes such journals as the Brazilian Electronic Journal of Economics, Internet Journal of Chemistry, and Journal of Cotton Science (all three now defunct), he excludes the most highly cited scientific journals producing printed and electronic issues, like Nature, Physical Review, Journal of the American Chemical Society, or such highly successful open-access journals as those of the Public Library of Science. It is the latter set that contains the journals we need to scrutinize if we are to discover what innovations, if any, have surfaced and are likely to be widely adopted in the future. These journals have the robust readership, the prestige, the financial resources, and the technical capacity necessary to introduce web-based innovations on a large scale. It is in these that the Internet revolution is now most visible. Still, among all scientific journals today, whether print or electronic, there remains a conservative core at this revolution’s center, a still point in the turning world of knowledge generation and communication.

Abstract:
Successful group work is a critical facet of engineering design. In addition to simply increasing the manpower available to solve a particular problem, team settings also leverage the variety of thinking offered by each individual. There are any number of functional behaviors that one might offer a team. This paper explores the idea that design journal records can provide key insight into the functional activities taken on by team members. The main questions asked by this study include (1) Can design journals provide consistent information about an individual’s functional behavior? (2) Are individuals likely to shift behaviors over the course of the project’s timeline? (3) Do individuals adapt to compensate for design behavior changes in other team members? The data in this study was collected from five volunteer teams of five to six undergraduate students each (total N = 29). At the time of their participation in the study, the volunteers were enrolled in the University of Maryland’s mechanical engineering capstone design course, Integrated Product and Process Development. Four of the teams participated in fall 2015 and one team participated in spring 2014. Participants maintained individual journals throughout their semester-long design projects, after receiving a set of guidelines to steer but not restrict journal usage. After the projects were completed, journals were coded using a previously validated coding scheme which associates each journal entry with a design behavior class and activity. Findings for this pilot study were very encouraging. Design journals proved to be a viable source of information about the functional behaviors of individuals. The majority of the undergraduate participants in this study were found to regularly shift their focuses to different behaviors as their projects progressed. When these shifts occurred, other team members regularly shifted to accommodate the change and maintain overall similar levels of activity in each area of functional behavior for the team as a whole throughout the project’s timeline.

Abstract:
This paper is the summary report on work started in 2007, and initially introduced in a presentation at the joint ASME – TTCI Bearing Symposium in Chicago in September of 2007 [1]. The identification of the root cause(s) for “warm bearing trend” temperatures has also been the subject of other technical papers [2, 3]. Traditional railroad journal bearing hot box detector (HBD) systems monitor journal bearing temperatures, and typically provide an alarm based on a measured in-service bearing absolute temperature, or against a programmed “delta” over the ambient temperature level. More recently, bearing operating temperatures have been statistically analyzed for temperature “trending”, and identification of temperature “outliers”, or bearings which display a higher temperature relative to the majority of bearings in the same train. AAR rules now facilitate the removal from service of bearings which either: 1) exceed traditionally defined limits, or 2) meet the statistical criteria set forth by these newly established AAR industry rules, to ideally prevent or eliminate “burn off journals” and potential derailments. This study is focused on testing of railroad journal bearings that were removed from service for “Why Made Code 50” (an “overheated” journal bearing), and exhibited no visually obvious external signs of distress. Dynamic testing and a corresponding tear down investigation to determine the root cause(s) for the elevated temperature was performed for the trend and mate bearings. This dynamic rig testing and corresponding investigation(s) have resulted in the determination of a significant and potential root cause for warm trend bearings.

Abstract:
This paper presents an efficiency study for scalable microwave waste management. When waste with carbon content is subjected to volume power densities on the order of 0.25W/cm3 at GHz frequencies, it converts to solid coke fuel with oil and gas bi-products that can further be processed for fuel, leaving no trace. For an efficient process, a well-controlled uniform RF field should be maintained in a non-uniform and time-variable material. We are developing a 2.45-GHz active microwave cavity with solid-state (GaN) spatially power combined sources for lower volumes, Fig.1. In the energy balance calculations, the input energy into the system consists of the waste chemical energy and the DC electrical energy used to obtain the RF power with an efficiency that can reach 70% for kW power levels. The efficiency of RF power conversion to heat in the waste mass is calculated from full-wave simulations for typical waste mixtures and ranges from 10 to 90% depending on the material and cavity filling. The output energy estimates are collected from various pyrolysis process descriptions, e.g. [1], with the total energy being that of the solid fuel (35MJ/kg) and oil caloric values, e.g. 40MJ/kg for plastics and about 10-15MJ/kg for nonplastics [2]. A byproduct is flue gas which can be converted to Syngas [3]. The total worse-case carbon footprint balance (0.3-3) calculations will be presented. Fig. 1.

Abstract:
This work presents the novel design of a smart hydrodynamic journal bearing with adjustable radial clearance. The dynamic behavior of this bearing was mathematically modeled and examined. Finite Element Analyses were conducted to determine the effort needed to change and maintain a desired value for the radial clearance. First, the bearing set was modelled as a two-degrees-of-freedom dynamic system. For an initial value of a radial clearance of c = 0.0508 mm, the bearing set exhibited an unstable behavior under its postulated operating condition. A Generic Algorithm (GA) was used to define an objective function so that an optimum value of c could be determined in order to ring the bearing into a stable operating condition. The GA determined the value of radial clearance of c = 0.0051 mm for this purpose. Second, a Jeffcott rotor was modeled as an eight-degrees-of-freedom vibratory stem supported by two identical smart bearings. For an initial value of c = 0.025 mm, the disk’s peak-to-peak vibrations amplitude was determined to be 8 × 10−5 meter and 8.5 × 10−5 m along two orthogonal axes of a reference frame respectively. The GA was used to determine a new value for the radial clearance of the supporting bearings in order to reduce the disk’s vibration level. A new value of radial clearance c was determined to be 0.095 mm which in turn reduced the vibrations of the dick from 8 × 10−5 and 8.5 × 10−5 meter to 3.5 × 10−5 and 2.5 × 10−5 m respectively.

Abstract:
In this work, the researchers explore how a professional engineering designer documents thoughts during the design process. This research will increase understanding of design thinking, improve the effectiveness of the design profession, and create tools for design education. Analyzing professional design behavior is traditionally done using timed design activities that are audio and video recorded to collect design data. The methodology used here is to analyze a set of handwritten design journals used for one long-term project. A comprehensive cognitive coding scheme is applied that has been verified by applying it to the data set and refined through iteration. The coding scheme has also been validated by producing comparative results to similar design studies found in the literature such as Atman, Suwa, and Jain. The results found that the professional was very detailed, spent a considerable amount of time on project management and that students are recording in the design journal for different reasons and at different times during the design process than the professional.

Abstract:
The article presents the calculation results of dynamic coefficients of hydrodynamic slide bearings obtained using three different methods. The numerical analysis based on a linear and nonlinear algorithm was carried out. The software developed at the Institute of Fluid-Flow Machinery PAN was applied for this purpose. In the experimental research, we used the impulse response method for the determination of dynamic coefficients of hydrodynamic bearings. This method is based on a linear algorithm and allows the calculation of stiffness, damping and mass coefficients for the rotor – bearings system. It allows calculating the complete set of coefficients in only one calculation step. During experimental research, vibrations of the rotor supported on two slide bearings are excited using an impact hammer at the middle part of the shaft. Stiffness, damping and mass coefficients are determined after the analysis of displacements of the journals and the registered excitation forces. The shaft mass is known, therefore mass coefficients can be used for quick verification of the obtained results — by comparing their values with the shaft mass. The experimental tests were carried out on the test rig produced by SpectraQuest. The basic dynamic characteristics of the test rig were determined in the framework of this research, including vibration trajectories of the journals for both bearings — at rotational speeds between 2250 and 6000 rpm. In this speed range, a resonant speed of the rotor was noticed. The vibration trajectories of the journals were used to verify calculated coefficients of the hydrodynamic slide bearings. Since the tested system exhibits nonlinear properties, the three different calculation methods produced large differences in results. The numerical calculations conducted with a linear algorithm provide only one set of stiffness and damping coefficients for each rotational speed (two main and two cross-coupling coefficients for each bearing). In the case of calculations utilizing nonlinear algorithm, the values of coefficients vary over time, notwithstanding the fact that the rotational speed is a fixed value. In each time step, we have different values of stiffness and damping coefficients of the hydrodynamic bearings. In the case of calculations based on the results obtained from experimental research, we receive one set of coefficients for each rotational speed, just as it is for the linear algorithm. The mean and standard deviation of stiffness, damping and mass coefficients are obtained by repeating many times experimental tests followed by statistical calculations. To get values of the coefficients for more than one rotational speed, calculations must be made for each one separately. As a matter of fact, most mechanical systems exhibit certain nonlinear properties. In rotating machinery, we sometimes face distortions of their operation caused by, for example, couplings or supporting structures. In the ideal case, if the system had linear properties and operated correctly without any distortion, the results obtained from all three methods would be the same. The reality is that the experimentally and numerically determined coefficients of the hydrodynamic journal bearings differed, and their differences were discussed in this article. These differences arise from the adopted assumptions and abilities of the three different calculation models. In numerical calculations based on a linear algorithm, it is assumed that the bearing journal is in static equilibrium during its operation. For nonlinear calculations, the solution is found by iterations. The stiffness and damping coefficients are determined for sufficiently small time steps such that we can replace their values in every position of the bearing journal. In experimental research, it is essential that the bearing operation should be considered as the operation in the linear range.

Abstract:
In this paper, analytical and numerical analyses of radial and tangential velocities and pressure of lubricant film have been considered in an eccentric journal bearing. A 2D flow of shear-thinning viscous fluid is followed by Carreau-Yasuda mathematical model between two eccentric cylinders. The model is mathematically conserved from eccentric coordinate to concentric coordinate due largely to easy solution. Therefore, the PDE equations were converted to the ODE equations with a set of nonlinear algebraic first order equations with their boundary conditions. These kinds of equations are called boundary value problems (BVP) that can be solved with shooting method. The results are compared with 2D numerical simulation in the Fluent software. Lubricant tangential velocity and pressure distributions are examined in the dynamic journal bearing. The comparison of the results revealed that numerical analysis as same as analytical approach is a reliable method for determining lubricant motion in the gap.

Full text
Abstract:
Although gas lubricated Herringbone Grooved Journal Bearings (HGJB) are known for high rotordynamic stability thresholds, small clearance to diameter ratios are required for stable rotor operation. Tight clearances not only increase bearing losses but also yield challenging manufacturing and assembly tolerances, which ultimately translate into cost. Traditionally, the grooves of HGJB are of helical nature with constant cross-section and pitch. The current paper aims at increasing the clearance to diameter ratio and the stability threshold of grooved bearings by introducing enhanced groove geometries. The axial evolution of groove width, depth and local pitch are described by individual 3rd order polynomials with four interpolation points. The expression for the smooth pressure distribution resulting from the narrow groove theory is modified to enable the calculation of bearing properties with modified groove patterns. The reduced order bearing model is coupled to a linear rigid body rotordynamic model for predicting the whirl speed map and the corresponding stability. By introducing a critical mass parameter as a measure for stability, a criterion for the instability onset is proposed. The optimum groove geometry is found by coupling the gas bearing supported rotor model with a multi-objective optimizer. By maximizing both the clearance to diameter ratio and the rotordynamic stability it is shown that with optimal groove geometry, which deviates from helicoids with constant pitch and cross-section, the critical mass parameter can be improved by more than one order of magnitude compared to traditional HGJB geometries. The clearance to diameter ratio can be increased by up to 80% while keeping the same stability margin, thus reducing both losses and manufacturing constraints. The optimum groove pattern distributions (width ratio, angle and depth) are summarized for a variety of L/D ratios and for different compressibility numbers in a first attempt to set up general design guidelines for enhanced gas lubricated HGJB.

Boedo, S. "A Hybrid Mobility Solution Method for Dynamically Loaded Misaligned Journal Bearings." In ASME/STLE 2012 International Joint Tribology Conference. American Society of Mechanical Engineers, 2012. http://dx.doi.org/10.1115/ijtc2012-61225.

Full text
Abstract:
This paper presents a hybrid mobility solution approach to the analysis of dynamically loaded misaligned journal bearings. Mobility data obtained for misaligned bearings (calculated from a finite element representation of the Reynolds equation) are compared with existing curve-fitted mobility maps representative of a perfectly aligned bearing. A relative error analysis of mobility magnitude and direction provides a set of misaligned journal bearing configurations (midplane eccentricity ratio and normalized misalignment angle) where existing curve-fitted mobility map components based on aligned bearings can be used to calculate the resulting journal motion. For bearing configurations where these mobility maps are not applicable, the numerical simulation process proceeds using a complete finite element solution of the Reynolds equation. A set of numerical examples representing misaligned main and connecting rod bearings in a four-stroke automotive engine illustrate the hybrid solution method. Substantial savings in computational time are obtained using the hybrid approach over the complete finite element solution method without loss of computational accuracy.

Abstract:
Abstract The present paper proposes the use of non linear model updating applying unrestricted optimization method, in order to obtain a methodology, which allows the calibration of mathematical models in rotating systems. An experimental set up for this purpose consists of a symmetric rotor, on a rigid foundation supported by two hidrodynamic cylindrical bearings and with a central disk of considerable mass, working as na unbalancing excitation force. Once the numeric and experimental values are obtained, error vectors are defined, which are the minimization parameters, through the variation of the numeric model parameters. The method presented satisfactory results, as it was able to calibrate the mathematical model, and then to obtain reliable responses for the physical system studied. The research also presents a contribution for the rotating machine desing area as it presents a relatively simple methodology on the updating and revalidation of computacional models for machines and structures.

Full text
Abstract:
This summary reviews evidence on the urban flooding impact, risk factors, and management and mitigation measures in Lagos and other cities in Nigeria. Flooding is a common problem every year in many cities across Nigeria, but the impacts of flooding are poorly documented. There is no consistent set of statistics at a national or sub-national level that can be used to compare the impacts of flooding across cities, and reports that focus on particular flood events are often incomplete. The literature notes the principal factors contributing to flood risk including uncontrolled urban growth, inadequate and poorly-maintained drainage systems, solid waste management practices, weakness in institutional capacity and coordination, and warning systems and public awareness. The evidence base for flood impacts, risks, and mitigation efforts at the city level in Nigeria is limited, and much of the information available is low quality, inconsistent, or outdated. Many rely on surveys of city residents rather than objective empirical data, and some of these surveys appear to be poorly designed. A significant number of the academic publications available have been published in non-mainstream journals without the usual level of academic peer review. Recent information is scarce, and a significant amount of the available evidence dates from 2011 and 2012, which coincides with an episode of nationwide flooding that was among the worst in Nigeria’s history.

African Open Science Platform Part 1: Landscape Study. Academy of Science of South Africa (ASSAf), 2019. http://dx.doi.org/10.17159/assaf.2019/0047.

Abstract:
This report maps the African landscape of Open Science – with a focus on Open Data as a sub-set of Open Science. Data to inform the landscape study were collected through a variety of methods, including surveys, desk research, engagement with a community of practice, networking with stakeholders, participation in conferences, case study presentations, and workshops hosted. Although the majority of African countries (35 of 54) demonstrates commitment to science through its investment in research and development (R&D), academies of science, ministries of science and technology, policies, recognition of research, and participation in the Science Granting Councils Initiative (SGCI), the following countries demonstrate the highest commitment and political willingness to invest in science: Botswana, Ethiopia, Kenya, Senegal, South Africa, Tanzania, and Uganda. In addition to existing policies in Science, Technology and Innovation (STI), the following countries have made progress towards Open Data policies: Botswana, Kenya, Madagascar, Mauritius, South Africa and Uganda. Only two African countries (Kenya and South Africa) at this stage contribute 0.8% of its GDP (Gross Domestic Product) to R&D (Research and Development), which is the closest to the AU’s (African Union’s) suggested 1%. Countries such as Lesotho and Madagascar ranked as 0%, while the R&D expenditure for 24 African countries is unknown. In addition to this, science globally has become fully dependent on stable ICT (Information and Communication Technologies) infrastructure, which includes connectivity/bandwidth, high performance computing facilities and data services. This is especially applicable since countries globally are finding themselves in the midst of the 4th Industrial Revolution (4IR), which is not only “about” data, but which “is” data. According to an article1 by Alan Marcus (2015) (Senior Director, Head of Information Technology and Telecommunications Industries, World Economic Forum), “At its core, data represents a post-industrial opportunity. Its uses have unprecedented complexity, velocity and global reach. As digital communications become ubiquitous, data will rule in a world where nearly everyone and everything is connected in real time. That will require a highly reliable, secure and available infrastructure at its core, and innovation at the edge.” Every industry is affected as part of this revolution – also science. An important component of the digital transformation is “trust” – people must be able to trust that governments and all other industries (including the science sector), adequately handle and protect their data. This requires accountability on a global level, and digital industries must embrace the change and go for a higher standard of protection. “This will reassure consumers and citizens, benefitting the whole digital economy”, says Marcus. A stable and secure information and communication technologies (ICT) infrastructure – currently provided by the National Research and Education Networks (NRENs) – is key to advance collaboration in science. The AfricaConnect2 project (AfricaConnect (2012–2014) and AfricaConnect2 (2016–2018)) through establishing connectivity between National Research and Education Networks (NRENs), is planning to roll out AfricaConnect3 by the end of 2019. The concern however is that selected African governments (with the exception of a few countries such as South Africa, Mozambique, Ethiopia and others) have low awareness of the impact the Internet has today on all societal levels, how much ICT (and the 4th Industrial Revolution) have affected research, and the added value an NREN can bring to higher education and research in addressing the respective needs, which is far more complex than simply providing connectivity. Apart from more commitment and investment in R&D, African governments – to become and remain part of the 4th Industrial Revolution – have no option other than to acknowledge and commit to the role NRENs play in advancing science towards addressing the SDG (Sustainable Development Goals). For successful collaboration and direction, it is fundamental that policies within one country are aligned with one another. Alignment on continental level is crucial for the future Pan-African African Open Science Platform to be successful. Both the HIPSSA ((Harmonization of ICT Policies in Sub-Saharan Africa)3 project and WATRA (the West Africa Telecommunications Regulators Assembly)4, have made progress towards the regulation of the telecom sector, and in particular of bottlenecks which curb the development of competition among ISPs. A study under HIPSSA identified potential bottlenecks in access at an affordable price to the international capacity of submarine cables and suggested means and tools used by regulators to remedy them. Work on the recommended measures and making them operational continues in collaboration with WATRA. In addition to sufficient bandwidth and connectivity, high-performance computing facilities and services in support of data sharing are also required. The South African National Integrated Cyberinfrastructure System5 (NICIS) has made great progress in planning and setting up a cyberinfrastructure ecosystem in support of collaborative science and data sharing. The regional Southern African Development Community6 (SADC) Cyber-infrastructure Framework provides a valuable roadmap towards high-speed Internet, developing human capacity and skills in ICT technologies, high- performance computing and more. The following countries have been identified as having high-performance computing facilities, some as a result of the Square Kilometre Array7 (SKA) partnership: Botswana, Ghana, Kenya, Madagascar, Mozambique, Mauritius, Namibia, South Africa, Tunisia, and Zambia. More and more NRENs – especially the Level 6 NRENs 8 (Algeria, Egypt, Kenya, South Africa, and recently Zambia) – are exploring offering additional services; also in support of data sharing and transfer. The following NRENs already allow for running data-intensive applications and sharing of high-end computing assets, bio-modelling and computation on high-performance/ supercomputers: KENET (Kenya), TENET (South Africa), RENU (Uganda), ZAMREN (Zambia), EUN (Egypt) and ARN (Algeria). Fifteen higher education training institutions from eight African countries (Botswana, Benin, Kenya, Nigeria, Rwanda, South Africa, Sudan, and Tanzania) have been identified as offering formal courses on data science. In addition to formal degrees, a number of international short courses have been developed and free international online courses are also available as an option to build capacity and integrate as part of curricula. The small number of higher education or research intensive institutions offering data science is however insufficient, and there is a desperate need for more training in data science. The CODATA-RDA Schools of Research Data Science aim at addressing the continental need for foundational data skills across all disciplines, along with training conducted by The Carpentries 9 programme (specifically Data Carpentry 10 ). Thus far, CODATA-RDA schools in collaboration with AOSP, integrating content from Data Carpentry, were presented in Rwanda (in 2018), and during17-29 June 2019, in Ethiopia. Awareness regarding Open Science (including Open Data) is evident through the 12 Open Science-related Open Access/Open Data/Open Science declarations and agreements endorsed or signed by African governments; 200 Open Access journals from Africa registered on the Directory of Open Access Journals (DOAJ); 174 Open Access institutional research repositories registered on openDOAR (Directory of Open Access Repositories); 33 Open Access/Open Science policies registered on ROARMAP (Registry of Open Access Repository Mandates and Policies); 24 data repositories registered with the Registry of Data Repositories (re3data.org) (although the pilot project identified 66 research data repositories); and one data repository assigned the CoreTrustSeal. Although this is a start, far more needs to be done to align African data curation and research practices with global standards. Funding to conduct research remains a challenge. African researchers mostly fund their own research, and there are little incentives for them to make their research and accompanying data sets openly accessible. Funding and peer recognition, along with an enabling research environment conducive for research, are regarded as major incentives. The landscape report concludes with a number of concerns towards sharing research data openly, as well as challenges in terms of Open Data policy, ICT infrastructure supportive of data sharing, capacity building, lack of skills, and the need for incentives. Although great progress has been made in terms of Open Science and Open Data practices, more awareness needs to be created and further advocacy efforts are required for buy-in from African governments. A federated African Open Science Platform (AOSP) will not only encourage more collaboration among researchers in addressing the SDGs, but it will also benefit the many stakeholders identified as part of the pilot phase. The time is now, for governments in Africa, to acknowledge the important role of science in general, but specifically Open Science and Open Data, through developing and aligning the relevant policies, investing in an ICT infrastructure conducive for data sharing through committing funding to making NRENs financially sustainable, incentivising open research practices by scientists, and creating opportunities for more scientists and stakeholders across all disciplines to be trained in data management.
