The production of social science research in Nigeria: status and systemic determinants

Nigeria has a very large research system, with nearly 200 universities that employed more than 60,000 academic staff at the end of 2019. The country is also one of Africa’s largest producers of scientific research across all disciplines, surpassed only by South Africa and Egypt. In the social sciences, in particular, Nigeria is Africa’s second-largest producer of published research, after South Africa. However, the country’s social science research (SSR) production does not match the size of its SSR system. Using mixed methods, we come up with two important reasons for this: (i) research inputs are low, mainly because research is poorly funded and researchers devote too little time to research as a result of poor organisational climate, and (ii) the research support system is weak. No single institution currently has a clear mandate to centrally coordinate SSR in Nigeria. Consequently, research efforts are often duplicated and the limited research resources are spread too thin. Moreover, logistical support for research is missing or inefficient in most organisations. Therefore, improving research productivity in the country would require much stronger research coordination and wide-ranging improvements in the research climate.

A Cross-Sectional Study of Electronic Cigarette Use Among Chinese Adult Populations in Four Cities of China. Part II. Puffing Topography

Summary With the rapid popularity and increasing numbers of E-cigarette (EC) users, debates on possible health risks and regulation of EC products have attracted attention in public. As a useful means to help assessing the risks of EC consumers, puffing topography studies have come to be an important tool globally. In this paper, a cross-sectional epidemiological study on puffing topography of 511 EC consumers in four cities of China was conducted in January 2018. Data acquisition was based on a questionnaire and a Clinical Research Support System (CReSS) Pocket device for the smoking behavior recording. The results showed that EC consumers in the four cities were mainly young males, most of whom preferred tank systems with zero or low nicotine concentrations (1–5 mg/mL) in the liquid. The average puff volume, puff duration and inter-puff interval (IPI) were 87.2 mL, 1.97 s and 22.0 s, respectively. The factors that may have affected puffing topography such as product type, nicotine concentration, using time, smoking status and battery power were studied. The results suggest that the EC product type and the concentration of nicotine in EC liquids were the main factors that affected the puffing topography of the users. This study was the first study on the puff topography of Chinese EC consumers with a large number of participants. The results may not only help to more deeply understand smoking behavior and to better assess the potential risks for the EC users, but they may also supply useful information for the development of smoking machine regimes for ECs.

Applications of Wiki in web-based research support system

PurposeThis paper is to address the research gaps about Research Support System (RSS) as mentioned by earlier articles, and to provide a possible solution to develop an RSS for supporting academics in conducting their research.Design/methodology/approachThis study adopts a single-case study with the application of netnography. Data were collected from an ongoing-using Wiki and the data were analysed using the theoretical lens established from earlier articles.FindingsThe result confirmed the possibilities of using Wiki to establish a system for supporting research. The authors have established a 3-stage EDM (Establishment, Development, Management) process model for illustrating the steps.Research limitations/implicationsThis single-case study revealed the possibility for using Wiki as RSS for helping academics to conduct their research through providing support in preparing literature review, conducting project management and providing an archive for research methodologies. The paper also provided suggestion for practitioners on the implementation of the RSS.Originality/valueThis paper presents one of the earliest studies for developing a model to explain how to develop an RSS that gives a more concrete definition of RSS and outline a process of using Wiki as an RSS.

A Procedure to Standardize Puff Topography During Evaluations of Acute Tobacco or Electronic Cigarette Exposure

Introduction Documenting factors that influence differential sensitivity to acutely inhaled nicotine products requires carefully controlling the amount of exposure (dose), and thus a procedure by which to control such exposure. Methods We evaluated consistency of puff volume from intermittent acute exposures to smoked tobacco cigarettes (study 1, n = 45, plus a comparison study of uninstructed use with n = 59) and to vaped electronic cigarettes (e-cigarettes; study 2, n = 27 naive to e-cigarettes) in adult-dependent smokers. All in primary studies 1 and 2 participated in research administering different nicotine levels in each product under blind conditions, one per session using within-subject designs. In both studies, participants followed an automated instructional procedure on a computer monitor standardizing the timing and amount of exposure to each product during a given trial, with four trials per session, each separated by 20 minutes. Puff volume per trial via Clinical Research Support System (CReSS) was the primary dependent measure to determine consistency across trials via intraclass correlation coefficients (ICCs). Results Control over topography with both inhaled products was demonstrated by highly significant ICCs for puff volume across trials. Instructed control with own brand was generally better in study 1 than with uninstructed smoking in the comparison sample, as expected. As intended, reliability of puff volume generally did not differ by menthol preference or sex in either study, but ICCs in study 2 tended to be lower for some men using the placebo e-cigarette. Conclusions This instructional procedure may substantially improve control over amounts of acute exposure to tobacco or e-cigarette use. Implications Control over topography in studies of acute exposure to these inhaled products can potentially aid validity of research into differential sensitivity to use, so findings can be attributed to factors of interest and not to variable exposure. Our procedure minimized variability in exposure to the same product and between moderate nicotine products, but remaining differences suggest that compensation for very low or no nicotine commercial products may be difficult to totally eliminate with these instructions alone. Further study is needed to determine this procedure’s utility with other inhaled products among experienced users and when comparing different products in between-groups analyses.

The Application of Commercially Available Mobile Cigarette Topography Devices for E-cigarette Vaping Behavior Measurements

Introduction The ability to reliably measure real-world vaping behavior is critical to understand exposures to potential toxins. Commercially available mobile topography devices were originally designed to measure cigarette puffing behavior. Information regarding how applicable these devices are to the measurement of electronic cigarette (e-cigarette) vaping topography is needed. Methods Clinical Research Support System (CReSS; Pocket) and Smoking Puff Analyzer Mobile (SPA-M) topography devices were tested against the calibrated laboratory-based smoking puff analyzer duplicator (SPA-D) device combined with an analytical smoking machine that generates programmable puffs with high precision. Puff topography of e-cigarettes was measured over a range of puff volumes (10–130 mL) at 2 and 5 s puff durations (using bell- and square-shaped puffs). “Real-world” topography data collected from 10 participants during 1 week of at-home vaping were also analyzed. Recording anomalies and limitations of the devices, such as accuracy of detection of the puff end, flow rate dropouts, unreported puffs, and abandoned vaping sessions for the CReSS, and multi-peak puffs for the SPA-M were defined. Results The accuracy of puff volumes and durations was determined for both devices. The error for SPA-M was generally within ±10%, whereas that for the CReSS varied more widely. The CReSS consistently underestimated puff duration at higher flow rates. Conclusions CReSS and SPA-M topography devices can be used for real-world e-cigarette topography measurements, but researchers have to be aware of the limitations. Both devices can provide accurate measurements only under certain puff parameter ranges. The SPA-M provided more accurate measurements under a wider range of puffing parameters than the CReSS. Summary data reported by both devices require thorough analysis of the raw data to avoid misleading data interpretation. Implications Results of this study provide researchers with valuable information about the capability of commercially available cigarette topography devices to measure real-world vaping behaviors. The differing measurement ranges of the two devices and puff recording limitations and anomalies should be taken into account during analysis and interpretation of real-world data.
