Coverage and Framing of Emerging STI and STEM by Four Major Nigerian Newspapers and Implications for National Development

In Nigeria, there is a gross deficit of empirical research on emerging STI content in the media. This study investigated four prominent newspapers in Nigeria to ascertain the extent to which STEM and emerging STI are covered and framed. We posed the following research questions covering reportage, sourcing, framing, and implications. The methodology involved a content/framing analyses of Daily Trust, Leadership, The Guardian and The Punch. A census sampling of 728 newspaper issues was conducted covering a period of six months spanning between December 1, 2020 and May 31, 2021. The results indicate a near zero coverage of emerging STI in the four dailies. Other results show that of the eight areas of STEM examined, medical/health sciences (48%), agricultural sciences (24%) and ICTs/engineering (19%) received more coverage. Earth/environmental sciences, physical and chemical sciences, marine, space, and mathematical sciences were accorded near zero coverage. On sourcing of STEM stories in the four dailies, 54% was sourced in-house by the journalists, 33% came from national STI institutions, while 13% was obtained from foreign and internet sources. On framing, 42% of STEM stories were framed in terms of health, risk, and safety; 39% in economic and political frame, while academic, environmental, ethical and “other frames scored between 7% and below. The conclusion of the study is that newspaper coverage of emerging STI was near zero reflecting and projecting the dismal status of emerging STI in Nigeria while the coverage and framing of STEM depicted the media agenda of concentration on medical, agricultural, and ICT endeavours to the neglect of others

Coverage and Framing of Emerging STI and STEM by Four Major Nigerian Newspapers and Implications for National Development

In Nigeria, there is a gross deficit of empirical research on emerging Science, Technology, and Innovation (STI) content in the media. This paper focuses on investigating four prominent newspapers in Nigeria to ascertain the extent to which Science, Technology, Engineering, and Mathematics (STEM) and emerging STI are covered and framed. We posed research questions covering reportage, sourcing, framing, and implications. The methodology involved content/framing analysis of Daily Trust, Leadership, The Guardian, and The Punch newspapers. A census sampling of 728 newspaper issues was conducted covering a period of six months spanning between December 1, 2020, and May 31, 2021. The results indicate a near zero coverage of emerging STI in the four dailies. Other results show that of the eight areas of STEM examined, medical/health sciences (48%), agricultural sciences (24%), and ICTs/engineering (19%) received more coverage. Earth/environmental sciences, physical and chemical sciences, marine, space, and mathematical sciences were accorded near zero coverage.

On framing, 42% STEM stories were framed in terms of health, risk, and safety; 39% in economic and political frame; while academic, environmental, ethical and “other” frames scored between 7% and below. The conclusion of the study is that newspaper coverage of emerging STI was near zero reflecting and projecting the dismal status of emerging STI in Nigeria while the coverage and framing of STEM depicted the media agenda of concentration on medical, agricultural, and ICT endeavours to the neglect of others. Deeper coverage and broader framing of emerging STI are germane to national development

Поверхностные скорости и айсберговый сток ледникового купола Академии Наук на Северной Земле

We have determined the ice-surface velocities of the Academy of Sciences Ice Cap, Severnaya Zemlya, Russian Arctic, during the period November 2016 – November 2017, using intensity offset-tracking of Sentinel-1 synthetic-aperture radar images. We used the average of 54 pairs of weekly velocities (with both images in each pair separated by a12-day period) to estimate the mean annual ice discharge from the ice cap. We got an average ice discharge for 2016–2017 of 1,93±0,12 Gt a−1, which is equivalent to −0,35±0,02 m w.e. a−1 over the whole area of the ice cap. The difference from an estimate of ~1,4 Gt a−1 for 2003–2009 can be attributed to the initiation of ice-stream flow in Basin BC sometime between 2002 and 2016. Since the front position changes between both periods have been negligible, ice discharge is equivalent to calving flux. We compare our results for calving flux with those of previous studies and analyse the possible drivers of the changes observed along the last three decades. Since these changes do not appear to have responded to environmental changes, we conclude that the observed changes are likely driven by the intrinsic characteristics of the ice cap governing tidewater glacier dynamics.По 54 парам космических снимков Sentinel‐1, сделанных с ноября 2016 г. по ноябрь 2017 г., определены скорости движения ледникового купола Академии Наук на Северной Земле. На этой основе оценён среднегодовой расход льда в море этого купола (1,93±0,12 Гт/год), установлены основные пути стока льда, проведено сравнение с прежними оценками

The economics of ecosystem services of tree-based intercropping systems

Paper presented at the 13th North American Agroforesty Conference, which was held June 19-21, 2013 in Charlottetown, Prince Edward Island, Canada.In Poppy, L., Kort, J., Schroeder, B., Pollock, T., and Soolanayakanahally, R., eds. Agroforestry: Innovations in Agriculture. Proceedings, 13th North American Agroforestry Conference, Charlottetown, Prince Edward Island, Canada, June 19-21, 2013.The paper aims to determine the potential environmental benefits of multifunctional tree-based intercropping (TBI) systems. Here we evaluate ten ecosystem services using a mix of mathematical models for quantification and economic valuation. The results reveal a total annual margin of 2 558 CAN$ha-1y-1. The economic value of combined non-market services is 1 634 CAN$ ha-1y-1, which is higher than the value of marketable products (i.e. timber and agricultural products). The present value of the services for a rotation of 40 years is 54 782 CAN$ ha-1, about a third of which is contributed by agricultural products. Water quality regulation ranked highest among the non-market benefits followed by air quality maintenance, soil quality regulation, biological control, and pollination.Mahbubul Alam (1), Alain Olivier (1), Alain Paquette (2), J�rôme Dupras (3), Jean-Pierre Rev�ret (4) and Christian Messier (5) ; 1.

The definitive version was published in BioScience 63 (2013): 49-54, doi:10.1525/bio.2013.63.1.10.Fertilizer-intensive agriculture has been integral to increasing food production over the past half century but has been accompanied by environmental costs. We use case studies of phosphorus fertilizer use in the world’s most productive soybean-growing regions, Iowa (United States), Mato Grosso (Brazil), and Buenos Aires (Argentina), to examine influences of management and soil type on agriculture’s most prevalent phosphorusrelated environmental consequences: eutrophication and consumption of Earth’s finite phosphorus reserves. With increasing phosphorus inputs, achieving high yields on tropical soils with high phosphorus-binding capacity is becoming more common. This system has low eutrophication risks but increases demands on phosphorus supplies. In contrast, production in traditional breadbaskets, on soils with lower phosphorus-binding capacities, is being sustained with decreasing phosphorus inputs. However, in these regions, historical overuse of phosphorus may mean continued eutrophication risk even as pressures on phosphorus reserves diminish. We focus here on soybean production but illustrate how achieving sustainable agriculture involves an intricate optimization of local, regional, and global considerations.SP is supported by the Andrew Mellon Foundation, and CN and SHR’s work in Mato Grosso was funded by National Science Foundation grant no.

Acanthamoeba genotype T4 from the UK and Iran and isolation of the T2 genotype from clinical isolates

The majority of the keratitis-causing Acanthamoeba isolates are genotype T4. In an attempt to determine whether predominance of T4 isolates in Acanthamoeba keratitis is due to greater virulence or greater prevalence of this genotype, Acanthamoeba genotypes were determined for 13 keratitis isolates and 12 environmental isolates from Iran. Among 13 clinical isolates, eight (61.5 %) belonged to T4, two (15.3 %) belonged to T3 and three (23 %) belonged to the T2 genotype. In contrast, the majority of 12 environmental isolates tested in the present study belonged to T2 (7/12, 58.3 %), followed by 4/12 T4 isolates (33.3 %). In addition, the genotypes of six new Acanthamoeba isolates from UK keratitis cases were determined. Of these, five (83.3 %) belonged to T4 and one was T3 (16.6 %), supporting the expected high frequency of T4 in Acanthamoeba keratitis. In total, the genotypes of 24 Acanthamoeba keratitis isolates from the UK and Iran were determined. Of these, 17 belonged to T4 (70.8 %), three belonged to T2 (12.5 %), three belonged to T3 (12.5 %) and one belonged to T11 (4.1 %), confirming that T4 is the predominant genotype (S2 = 4.167; P = 0.0412) in Acanthamoeba keratitis
