Policy options of agricultural biotechnology R&D in Sub-Saharan Africa: key issues and aspects

This paper reviews the status of Agricultural Biotechnology in Sub-Saharan Africa. It addresses the potential economic benefits to Sub-Saharan Africa and the effect biotechnology policies may have on growth, production and poverty reduction. The extent to which agricultural biotechnology will compound or mitigate the constraints faced by smallholders/subsistence farmers is also discussed. The status of crop biotechnology research worldwide is reviewed and the influence of intellectual property rights (IPRs) and market concentration on the development and diffusion of biotechnology in Sub-Saharan Africa is analyzed. The paper also explores the potential of public-private partnerships and recommends policy measures and investments that could focus more biotechnology research on the problems of the poor and alleviate some of the concerns about the impacts of biotechnology.Policy Options; Intellectual Property; Biotechnology; Sub-Saharan Africa; Technology Diffusion

A stakeholder approach to investigating public perception and attitudes towards agricultural biotechnology in Ghana

A stakeholder survey was conducted in Ghana to assess the level of public perceptions and acceptance of agricultural biotechnologies. A total of 100 respondents drawn from academia, Non-governmental organizations, business community, government and other stakeholders were interviewed on their views on self-protection attitudes, health and economic benefits, skepticism and optimism about agricultural biotechnologies as well as the level of confidence in existing government regulatory systems to protect society against any negative effects of biotechnological issues. Although half of the sample interviewed did not accept biotechnologies in general and GM foods in particular, there was rather high approval of some specific health and economic benefits. About 80 percent of the sample interviewed lack confidence in existing government regulatory systems probably due to inadequate capacity. Upgrading of the existing regulatory system with adequate capacity to regulate the ethical and moral issues associated with biotechnologies and GM foods was recommendedBiotechnology, Stakeholder, Acceptance, GM Foods

Acceptance of biotechnology and social-cultural implications in Ghana

Despite major scientific progress in the application of biotechnology in agriculture, public attitudes towards biotechnology in general and genetically modified food (GM food) products in particular remain mixed in Africa. Examining responses on acceptance of GM food through a stakeholder survey in Ghana, it was established that half of the 100 people sample interviewed were not in favor of GM foods. To this group acceptance of GM foods would make farmers loose focus on the traditional ways of cultivation, putting the whole nation at the mercy of profit driven foreign companies who produce GM foods. In order to have clear and unbiased attitudes towards agricultural biotechnology in Africa, there is the need to substitute dominant ideologies in the way biotechnology research and dissemination are conducted in developed countries with tailor-made methodologies in developing countries. This paper emphasizes the social dynamic force of food focusing on the need for social shaping of biotechnologies to reflect local and regional needs. Respondents’ perceptions of GM foods suggest that food is seen as not just a commodity to be consumed but food has both cultural and national identities. Generally, people are identified by their consumption and nutrition lifestyles and therefore take pride in what they eat. A proposal is made to set biotechnology research agenda in the context of social choices; social scientific coalition of biotechnology with endogenous development pathways’ as opposed to ‘exogenous biotechnology research’. Also there is the need for adequate capacity building of the existing regulatory institutions to handle ethical and moral issues associated with biotechnology research since survey findings showed lacked of public confidence in them.Biotechnology; survey; acceptability; social shaping; Ghana

The HI - Star Formation Connection: Open Questions

We show data from the Survey of Ionization in Neutral Gas Galaxies (SINGG) and Survey of Ultraviolet emission in Neutral Gas Galaxies (SUNGG) which survey the star formation properties of HI selected galaxies as traced by H-alpha and ultraviolet emission, respectively. The correlations found demonstrate a strong relationship between the neutral ISM, young massive stars, and the evolved stellar populations. For example the correlation between R band surface brightness and the HI cycling time is tighter than the Kennicutt-Schmidt Star Formation Law. Other scaling relations from SINGG give strong direct confirmation of the downsizing scenario: low mass galaxies are more gaseous and less evolved into stars than high mass galaxies. There are strong variations in the H-alpha to UV flux ratios within and between galaxies. The only plausible explanations for this result are that either the escape fraction of ionizing photons or the upper end of the IMF varies with galaxy mass. We argue for the latter interpretation, although either result has major implications for astrophysics. A detailed dissection of the massive star content in the extended HI disk of NGC2915 provides a consistent picture of continuing star formation with a truncated or steep IMF, while other GALEX results indicate that star formation edges seen in Halpha are not always apparent in the UV. These and other recent results settle some old questions but open many new questions about star formation and its relation to the ISM.Comment: To appear in AIP Conference Proceedings, "The Evolution of Galaxies through the Neutral Hydrogen Window", Feb 1-3 2008, Arecibo, Puerto Rico, eds.

The Impact of a GenCyber Camp on In-service Teachers’ TPACK

The purpose of this study was to examine the impact of a GenCyber camp curriculum on teachers’ technology, pedagogy, and content knowledge (TPACK). The camp was designed to engage participants in developing the knowledge and skills to incorporate GenCyber Cybersecurity First Principles and GenCyber Cybersecurity Concepts (GenCyber, 2019) into their curriculums. Participants (37 middle and high school teachers from a variety of disciplines) attended one of two weeklong camps held at a Midwestern liberal arts university. Using the TPACK Self-Reflection and TPACK Self-Assessment Surveys, pre- and post-camp data were collected from participants. Findings indicate that participants demonstrated an increase in all domains of the TPACK framework from pre- to post-survey. The greatest increase was in Technological Pedagogy Knowledge (TPK) (0.57), followed by Pedagogical Content Knowledge (PCK) (0.51), and Technological Pedagogical Content Knowledge (TPACK) (0.46). GenCyber participants also demonstrated an average increase in pre- and post-test scores in all areas on the TPACK Self-Assessment Survey Results; however, individual results were mixed. The majority of participants (n=21), sixty percent, saw an increase in composite score from pre- to post, whereas 12 participants\u27 (34%) scores decreased from pre- to post, and two (6%) stayed the same. Findings indicate the GenCyber Camp provided in-service teachers with the knowledge and skills necessary to incorporate GenCyber Principles and Cybersecurity Concepts into their curriculum. Recommendations for teacher professional development on cybersecurity are made

Outcomes from an Entry-level Occupational Therapy Doctoral Practice-Scholar Apprenticeship Program

The introduction of the occupational therapy doctoral (OTD) program to the field of occupational therapy (OT) education was intended to advance the field by developing future leaders, increasing advanced practice, and promoting scholarship in practice. Limited information to date is available regarding outcomes of the OTD program related to the future research potential of graduates. One such approach to promoting the scholarship of practice among OTD graduates is the use of the practice-scholar model. The practice-scholar model is designed to build research skills among OTD students to encourage their ongoing commitment to evidence-based practice through implementing their own research in practice. Founded in 2014, the Northern Arizona University (NAU) entry-level OTD program has implemented the practice-scholar model through their practice-scholar apprenticeship (PSA) program. The NAU PSA program involves a mentorship experience with OTD students engaging in faculty and/or community clinician led research. The purpose of this paper is to share evaluation results of the NAU PSA program related to the research development among the program’s graduates. NAU OTD students completed pre and post surveys regarding their expectations towards research and a post qualitative feedback session. Students reported statistically significant improvements in their research self-efficacy skills. Qualitatively students identified their developed research skills, the importance of research and their desire to continue implementing research in the future. The field of OT should continue to identify structural ways to support research in practice to realize the potential of future OTD practitioners

Constraints on Voltage Sensor Movement in the Shaker K+ Channel

In nerve and muscle cells, the voltage-gated opening and closing of cation-selective ion channels is accompanied by the translocation of 12–14 elementary charges across the membrane's electric field. Although most of these charges are carried by residues in the S4 helix of the gating module of these channels, the precise nature of their physical movement is currently the topic of spirited debate. Broadly speaking, two classes of models have emerged: those that suggest that small-scale motions can account for the extensive charge displacement, and those that invoke a much larger physical movement. In the most recent incarnation of the latter type of model, which is based on structural and functional data from the archaebacterial K+ channel KvAP, a “voltage-sensor paddle” comprising a helix-turn-helix of S3–S4 translocates ∼20 Å through the bilayer during the gating cycle (Jiang, Y., A. Lee, J. Chen, V. Ruta, M. Cadene, B.T. Chait, and R. MacKinnon. 2003. Nature. 423:33–41; Jiang, Y., V. Ruta, J. Chen, A. Lee, and R. MacKinnon. 2003. Nature. 423:42–48.; Ruta, V., J. Chen, and R. MacKinnon. 2005. Cell. 123:463–475). We used two methods to test for analogous motions in the Shaker K+ channel, each examining the aqueous exposure of residues near S3. In the first, we employed a pore-blocking maleimide reagent (Blaustein, R.O., P.A. Cole, C. Williams, and C. Miller. 2000. Nat. Struct. Biol. 7:309–311) to probe for state-dependent changes in the chemical reactivity of substituted cysteines; in the second, we tested the state-dependent accessibility of a tethered biotin to external streptavidin (Qiu, X.Q., K.S. Jakes, A. Finkelstein, and S.L. Slatin. 1994. J. Biol. Chem. 269:7483–7488; Slatin, S.L., X.Q. Qiu, K.S. Jakes, and A. Finkelstein. 1994. Nature. 371:158–161). In both types of experiments, residues predicted to lie near the top of S3 did not exhibit any change in aqueous exposure during the gating cycle. This lack of state dependence argues against large-scale movements, either axially or radially, of Shaker's S3–S4 voltage-sensor paddle

Test Targets 10: A Collaborative effort exploring the use of scientific methods for color imaging and process control

Th ere are six papers that were written, peer reviewed, and published in Test Targets 10. Two papers focus on printing standardization and conformity assessment. Chung describes aims and tolerances specified in ISO 12647-2 and the use of color measurement and data analysis for conformity assessment. Urbain and Khoury describe data reception requirements in ISO 12647-2 and ISO 15930 and the use of a test pdf file to assess conformity of any pdf workflow. Test Targets 10 will likely be remembered as the publication that covers OBA (optical brightening agents). Two papers focus on OBA. Tian and Chung report the effect of paper containing OBA on printed colors and how such effect can be corrected using different mathematics. Sigg and Millward report the stability of OBA as a function of exposure to light over time. In addition, Gallery of Visual Interest shows side-by-side the visual effect of pictorial and synthetic color images printed on paper with and without OBA. Printing conformity is result-oriented and does not dictate the press calibration method used. The fifth paper, authored by Wang, compares the compatibility of two press calibration methods, TVI and G7, by means of gradation compensation and press run simulation. Printing conformity requires that correct inks and paper be used. Verifying that correct inks are used is outside the capability of a printer. Th e sixth paper, authored by Zhang, explores an alternative ink drawdown and ink verification method that could be implemented by printers. Test Forms is a regular feature of Test Targets. We are pleased to showcase pictorial color reference images, Roman 16 Reference Images, courtesy of Bundesverband Druck und Medien e.V. (bvdm), and many possible uses of these images for printing process control and for color management studies. For example, we can compare the appearance of an image printed from the supplied CMYK file with the image from a supplied RGB file that was converted to CMYK by a color management application
