REPRESENTATION OF YOUNG PEOPLE IN EKEGUSII PROVERBIAL METAPHORS: AN IMAGE SCHEMATIC ACCOUNT
No full textRepresentation of young people in Ekegusii proverbial metaphorsProverbial metaphors are useful resources for communicating known truths about life in a given
community. Most African proverbial metaphors, however, make reference to customs and situations
that might be unfamiliar to some language users especially young people. On the basis of this
background, this study employed image schemas to interpret Ekegusii proverbial metaphors that
allude to young people. The research was anchored within descriptive research design. Primary data
was collected from four Ekegusii respondents of an advanced age of at least seventy years old through
an interview schedule. The collected data were then subjected to the Metaphor Identification
Procedure Vrije Universiteit (MIPVU) in which four annotators were used to identify Ekegusii proverbial
metaphors. Seven Ekegusii proverbial metaphors that refer to young people were identified through
MIPVU. The identified proverbial metaphors were then subjected to the FORCE and CONTAINER
schemas and their subsidiary schemas for analysis. The paper reveals that there are norms and
customs regarding young people that are conveyed through Ekegusii proverbial metaphors. In
addition, image schemas are fundamental in explaining the role, place, and cultural expectations of
young men and women in Gusii. The study concludes that proverbial metaphors are useful tools of
communication, and should be interpreted using Cognitive Linguistics paradigm. Article visualizations:

Allelic Variation of Terpene Synthases Drives Terpene Diversity in the Wild Species of the Freesia Genus.
No full textWild species of the Freesia genus.Terpene synthases (TPSs) play pivotal roles in conferring the structural diversity of terpenoids, which are mainly emitted from flowers, whereas the genetic basis of the release of floral volatile terpenes remains largely elusive. Though quite similar in sequence, TPS allelic variants still function divergently, and how they drive floral terpene diversity in closely related species remains unknown. Here, TPSs responsible for the floral scent of wild Freesia species were characterized, and the functions of their natural allelic variants, as well as the causal amino acid residues, were investigated in depth. Besides the eight TPSs previously reported in modern cultivars, seven additional TPSs were functionally evaluated to contribute to the major volatiles emitted from wild Freesia species. Functional characterization of allelic natural variants demonstrated that allelic TPS2 and TPS10 variants changed enzymatic capacity while allelic TPS6 variants drove the diversity of floral terpene products. Further residue substitution analysis revealed the minor residues determining the enzyme catalytic activity and product specificity. The clarification of TPSs in wild Freesia species reveals that allelic TPS variants evolved differently to determine the interspecific floral volatile terpenes in the genus and might be used for modern cultivar improvement

the profiles of amino acids, polyphenols, and organic acids identified in the seeds. Our findings
demonstrated that red cabbage, broccoli, and buckwheat extracts exhibited significantly higher
antioxidant potential compared to the alfalfa extract. Moreover, buckwheat displayed the most signif
icant capacity for inhibiting alpha-glucosidase. Remarkably, broccoli and red cabbage demonstrated
substantial anti-glycation and lipase inhibitory potentials. We identified the presence of amino acids,
polyphenols, and organic acids in the extracts through untargeted metabolomics analysis. Correlation
analysis revealed that pyroglutamic acid positively correlated with all the investigated functional
properties. Most polyphenols made positive contributions to the functional properties, with the
exception of ferulic acid, which displayed a negative correlation with all tested biological activities.
Furthermore, gluconic acid and arabinonic acid among the organic acids identified displayed a
positive correlation with all the functional properties. These results strongly support the anti-diabetic,
anti-obesity, and anti-glycation potential of red cabbage, broccoli, and buckwheat seeds

MEDIA COVERAGE, CONTENT FRAMING AND AUDIENCE PERCEPTION OF WILDLIFE CONSERVATION DISCOURSE IN KENYA
Get PDFMain TextAudience perception of wildlife conservation discourse in Kenya has been negative as evidenced in the results of conservation efforts. The general objective of the study was: to investigate the influence of media coverage, content framing and audience perception of wildlife conservation discourse in Kenya. The specific objectives were to: examine the influence of the choice of media channel on audience perception; evaluate the timing of media messages on audience perception; investigate the effects of frequency of media messages on audience perception; assess the combined influence of choice of media channel, timing of media messages, and frequency of media messages on perception; and to investigate the moderating influence of content framing on the relationship between media coverage and audience perception of wildlife conservation discourse in Kenya. The study was anchored on framing and semantic meaning theories using a pragmatism philosophical paradigm. It employed a convergent parallel mixed methods design, combining quantitative and qualitative data for a comprehensive analysis. The target population consisted of 297 individuals, with a sample size of 133. Purposive sampling techniques were used to select 6 environmental journalists, a census identified 12 park managers, and through simple random sampling, 115 human-wildlife conflict resolution committee members joined the sample. Data collection tools comprised of interview guide for media practitioners and park managers, Focus Group Discussions guide targeting human-wildlife conflict resolution committee officials and a questionnaire administered to the other committee members. Qualitative data was thematically analyzed and presented in narrative form, while quantitative data underwent descriptive and inferential statistical analysis, with findings presented through linear texts and graphics. The study findings showed that there was lack of effective communication channels for wildlife conservation initiatives, which led to community resistance and jeopardize conservation efforts. The relationship between media channel choice and audience perception showed an R-squared value of 0.656, indicating that media channels explain 65.6% of the variation in perception. Timing of media messages had an R-squared value of 0.779, explaining 77.9% of perception variation. Frequency of messages had an R-squared value of 0.856, explaining 85.6% of variation. In each case, the calculated F-values were significantly greater than the critical F-values. Content framing was found to moderate the relationship between media coverage and perception, with a significant ANOVA result (F = 240.355; p-Value<0.05). This emphasizes the need for strategic communication approaches in wildlife conservation. The study concluded that when framing wildlife conservation messages, the target audiences were not satisfied with the manner in which these messages were communicated. The study findings will assist media practitioners in formulating guidelines for media coverage and content framing of wildlife conservation discourse. The study therefore recommended that practitioners should use correct media channels and effective content framing strategies in order to change audience perception of wildlife conservation.
Green synthesis of copper oxide nanoparticles and its efficiency in degradation of rifampicin antibiotic.
No full textGreen synthesis of copper oxide nanoparticlesIn recent ages, green nanotechnology has gained attraction in the synthesis of metallic nanoparticles due to their cost-effectiveness, simple preparation steps, and environmentally-friendly. In the present study, copper oxide nanoparticles (CuO NPs) were prepared using Parthenium hysterophorus whole plant aqueous extract as a reducing, stabilizing, and capping agent. The CuO NPs were characterized via UV–Vis Spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), powder X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and Dynamic Light Scattering (DLS). The UV–Vis spectra of CuO NPs showed a surface plasmonic resonance band to occur at 340 nm. FTIR analysis revealed the presence of secondary metabolites on the surface of CuO NPs, with a characteristic Cu–O stretching band being identified at 522 cm−1. Scanning electron micrographs and transmission electron micrographs showed that CuO NPs were nearly spherical, with an average particle of 59.99 nm obtained from the SEM micrograph. The monoclinic crystalline structure of CuO NPs was confirmed using XRD, and crystallite size calculated using the Scherrer-Debye equation was found to be 31.58 nm. DLS showed the presence of nanoparticle agglomeration, which revealed uniformity of the CuO NPs. Furthermore, the degradation ability of biosynthesized nanoparticles was investigated against rifampicin antibiotic. The results showed that the optimum degradation efficiency of rifampicin at 98.43% was obtained at 65℃ temperature, 50 mg dosage of CuO NPs, 10 mg/L concentration of rifampicin solution, and rifampicin solution at pH 2 in 8 min. From this study, it can be concluded that CuO NPs synthesized from Parthenium hysterophorus aqueous extract are promising in the remediation of environmental pollution from antibiotics. In this light, the study reports that Parthenium hysterophorus-mediated green synthesis of CuO NPs can effectively address environmental pollution in cost-effective, eco-friendly, and sustainable ways
"The Influence of Shared Vision on Organizational Ambidexterity in Coffee Marketing Co-operative Societies in Kenya”.
No full textinfluence of shared vision on organizational ambidexterity in coffee marketing co-operative societiesCoffee production in Kenya has plummeted, hurting the economy and worsening social inequality and poverty. Kenyan coffee marketing cooperative associations have failed to boost exports. Coffee is Kenya's main cash crop. Coffee is the country's principal foreign exchange earner, rural employment source, food security source, and revenue source. The reduction in coffee export earnings shows that coffee marketing cooperatives are inefficient and less flexible. This study examines how shared vision affects organizational ambidexterity. This transformational leadership-based study used exploratory and cross-sectional survey methodologies. The target audience was Kenyan coffee marketing cooperatives. The sample size was 242 Kenyan coffee marketing cooperative societies. A self-administered, semi-structured questionnaire collected primary data from cooperative society managers. The data was analyzed using descriptive and inferential statistics. Results show that shared vision favorably impacts organizational ambidexterity (R = 0.547, R2 = 0.299), explaining 29.9% of variation. Further, shared vision significantly affected organizational ambidexterity (P-value = 0.00). The study found that shared vision affected organizational ambidexterity. Thus, managers of coffee marketing cooperative societies should constantly discuss their vision with other employees to improve ambidexterity.
