A Studnet may enter the second (S.2) year of the NC course in Chemistry provided he obtains passes at GCE ‘O’ level in Chemistry, Physics, Mathematics and English Language. He then pursues a two‐year, part‐time course leading to the ONC in Chemistry. In an article published recently in TECHNICAL EDUCATION it was shown that the failure rate at both the ONC and HNC levels was very high. It was suggested that present syllabuses for courses leading to ONC and HNC were, in many instances, too traditional and too long. A syllabus designed for HNC students may be very suitable when viewed in isolation, but may lead to difficulties for both student and teacher if it has been constructed without reference to the appropriate ONC syllabus; or if it was constructed to make good anomalies in and omissions from the ONC syllabus. The result is that students who are successful at the ONC stage have inadequate understanding and knowledge of fundamental chemistry to profit from the HNC course. This discussion is mainly concerned with ONC schemes and syllabuses, although some of the remarks apply equally well to HNC courses.

The paper discusses broadly electronic publishing and types of electronic publications. An attempt has been made to group the select electronic resources of chemical information into portals, patents and dissertations, full‐text files with backfiles and e‐books, abstracting and indexing services, encyclopaedias and handbooks, periodic tables, property databases and specialty databases. The paper concludes that in delivering electronic information two major developments are gaining momentum as archives from major publishers and preprints from academic circles are used as alternative methods of accessing research information. Also, scholarly publication of chemical information in electronic form will continue to grow, adapting to meet changing needs of authors and readers alike.

The Chemistry Online Retrieval Experiment (CORE), a five‐year R&D project, was one of the earliest attempts to make a substantial volume of the text and graphics from previously published scholarly journals available to end‐users in electronic form, across a computer network. Since CORE dealt with material that had already gone through traditional print publication, its emphasis was on the process (and limitations) of conversion, the optimization of presentation, and use of the converted contents for readers. This article focuses on the user response to the system.

In this chapter, we examine the development of a technology path in the nanotube (NT) field – one of the most well-developed areas of nanotechnology. Although early developments suggested that there were equally viable pathways related to the development of carbon nanotubes (CNTs) and others made with organic molecules and polymers, carbon-based technologies became valorized. We show how the carbon science path developed and try to unpack how it happened. We argue that it was not due to the inherent efficiency or applications of CNTs, but to sociopolitical dynamics. Even though much intellectual property research focuses on patent-level analysis, we underscore the importance of patent categories as key cognitive elements that organize the different knowledge domains within the world of NT patenting. We show that interlinkages between patent categories are crucial to the formation and development of a particular technology path. In unpacking the selection of the carbon science path, we highlight the key role played by a cadre of star scientists and the political neglect of alternative pathways as the field herded toward the CNT path.

The purpose of this study was to understand the research data management practices of chemistry researchers in the five specialized federal universities of technology in Nigeria. Appropriate research data management practice ensures that research data are available for reuse by secondary users, and research findings can be verified and replicated within the scientific community. A poor research data management practice can lead to irrecoverable data loss, unavailability of data to support research findings and lack of trust in the research process.

An exploratory research technique involving semi-structured, oral and face-to-face interview is used to gather data on research data management practices of chemistry researchers in Nigeria. Interview questions were divided into four major sections covering chemistry researchers’ understanding of research data, experience with data loss, data storage method and backup techniques, data protection, data preservation and availability of data management plan. Braun and Clarke thematic analysis approach was adapted, and the Provalis Qualitative Data Miner (version 5) software was used for generating themes and subthemes from the coding framework and for presenting the findings.

Findings revealed that chemistry researchers in Nigeria have a good understanding of the concept of research data and its importance to research findings. Chemistry researchers have had several experiences of irrecoverable loss of data because of poor choice of storage devices, back-up methods and weak data protection systems. Even though the library was agreed as the most preferred place for long-term data preservation, there is the issue of trust and fear of loss of ownership of data to unauthorized persons or party. No formal data management plan is used while conducting their scientific research.

The research focused on research data management practices of chemistry researchers in the five specialized federal universities of technology in Nigeria. Although the findings of the study are similar to perceptions and practices of researchers around the world, it cannot be used as a basis for generalization across other scientific disciplines.

This study concluded that chemistry researchers need further orientation and continuous education on the importance and benefits of appropriate research data management practice. The library should also roll out research data management programs to guide researchers and improve their confidence throughout the research process.

Appropriate research data management practice not only ensures that the underlying research data are true and available for reuse and re-validation, but it also encourages data sharing among researchers. Data sharing will help to ensure better collaboration among researchers and increased visibility of the datasets and data owners through the use of standard data citations and acknowledgements.

This is a qualitative and in-depth study of research data management practices and perceptions among researchers in a particular scientific field of study.

Chemical databases have had a significant impact on the way scientists search for and use information. The purpose of this paper is to spark informed discussion and fuel debate on the issue of citations to chemical databases.

A citation analysis to four major chemical databases was undertaken to examine resource coverage and impact in the scientific literature. Two commercial databases (SciFinder and Reaxys) and two public databases (PubChem and ChemSpider) were analyzed using the “Cited Reference Search” in the Science Citation Index Expanded from the Web of Science (WoS) database. Citations to these databases between 2000 and 2016 (inclusive) were evaluated by document types and publication growth curves. A review of the distribution trends of chemical databases in peer-reviewed articles was conducted through a citation count analysis by country, organization, journal and WoS category.

In total, 862 scholarly articles containing a citation to one or more of the four databases were identified as only steadily increasing since 2000. The study determined that authors at academic institutions worldwide reference chemical databases in high-impact journals from notable publishers and mainly in the field of chemistry.

The research is a first attempt to evaluate the practice of citation to major chemical databases in the scientific literature. This paper proposes that citing chemical databases gives merit and recognition to the resources as well as credibility and validity to the scholarly communication process and also further discusses recommendations for citing and referencing databases.

The main purpose of this study is to determine India's position in publishing top research papers in chemistry as reflected in Science Direct. It also aims to find out authorship pattern, countries with major contributions, journals with high publication rates, etc.

Citation analysis methods were applied to study citations of 450 research papers in chemistry taken from the listing of top 25 papers in Science Direct database. The citations covered 18 issues of the Science Direct generated alert service for the period 2004‐2008. The bibliographic data were entered in Excel sheets for necessary analysis.

The studies revealed that, out of 450 research papers, 36 (8 per cent) are contributed by Indian researchers. In the ranking of contributing countries, India reserves third position after the USA and China. More than 86 per cent of Indian chemistry research papers were cited by others. As regards to number of citations, 25 per cent of Indian papers are cited between 10 and 25 times each. The journal Tetrahedron was found as the highest publishing journal with 71 (16 per cent) publications.

The paper presents a sense of the importance of Indian chemistry research, and as such informs that community, as well as researchers involved in citation analysis.

The outcome of the study is an original research work with citation analysis of top research papers in chemistry. The findings will have practical implications for Indian scientists, funding agencies and research establishments in different areas of chemical sciences.

The racial and ethnic representation of individuals in the workforce is not comparable to that in the general population. In 2010, African Americans constituted 12.6% of the US population. However, African Americans represented less than 5% of PhD recipients in 2010; African American women comprised less than 1% of the degrees awarded in that same year. These disappointing statistics have sparked conversations regarding the retention of underrepresented groups with a focus on what helps to ensure these individuals will transition through the science, technology, engineering, and mathematics (STEM) pipeline. This chapter provides insight into the elements of the Spelman College learning environment that empower women of African descent to become agents of their success while facilitating their movement through the STEM pipeline. The chapter focuses on interventions and resources developed in the Chemistry and Biochemistry Department to foster student-centered learning. Described herein are cocurricular strategies and course-based interventions are used synergistically to enhance student outcomes. The approach to curricular innovation is framed by theories related to community of inquiry (CoI), metacognition, agency, and self-regulated learning. Strategic institutional investments have underpinned these efforts. In addition to providing a snapshot of student outcomes, the authors discuss lessons learned along with the realities of engaging in this type of intellectual work to elucidate the feasibility of adopting similar strategies at other institutions.

This article introduces the application of informetric methods to the World Wide Web (WWW), also called Webometrics. A case study presents a workable method for general informetric analyses of the WWW. In detail, the paper describes a number of specific informetric analysis parameters. As a case study the Danish proportion of the WWW is compared to those of other Nordic countries. The methodological approach is comparable with common bibliometric analyses of the ISI citation databases. Among other results the analyses demonstrate that Denmark would seem to fall seriously behind the other Nordic countries with respect to visibility on the Net and compared to its position in scientific databases.

This study aims to apply some concepts of actuarial statistics to the authorship of Iranian ISI papers in the field of chemistry based on Price’s model. The study determines scientific birth rate, death rate, infant mortality rate, natural increase rate and life expectancy.

Price maintained that authors in each given period in any field fall into four categories including newcomers, transients, continuants and terminators. He suggested that actuarial statistics could be applied to authorship to calculate death rate and birth rate in scientific fields. A total 25,573 papers written by 59,661 Iranian chemistry authors between 1973 and 2012 were downloaded from Web of Science (WoS) and were subjected to statistical analysis.

The average birth rate was 66.7 per cent, the average death rate was 19.4 per cent, infant mortality rate was 51.2 per cent, average natural increase was 47.3 per cent, the average life expectancy was 1.98 years and the longest scientific age was 22 years. The results show that although a large number of people start their scientific activity, the number of those who terminate their activity in the same year as they start (infant mortality rate) is also large and little continuity exists in the publishing activities of Iranian chemists.

The findings have implications for the planning of human resources in science. They could help maintain a stable scientific labor force and decide for instance whether a larger number of scientists should be trained and hired, or the barriers should be removed so the existing scientists can work for more years. The limitation is that the study is restricted to ISI articles, although they are not the only kind of scientific output.

This is the first study of its kind on Iranian scientific output. It shows that the overall labor force in the field of chemistry in Iran was not satisfactory, as the majority of authors in each period are transients. There is a need for better planning for the labor force.
