Question Typology in Kenyan TV Argumentative Talk Shows

The argumentative talk on radio and TV has become a popular feature of media discourse in Kenya. Question-answer sequences as the talk unfolds through the joint participation of co-participants in the talk have emerged as a means to put argumentative talk into effect. Yet, the nature of questions and their categorization remain little understood. Given the recursive nature of question-answer sequences, this paper investigates question typology that sets apart argumentative talk shows from other types of talk. The data consists of transcripts from two Kenyan TV argumentative talk shows: Checkpoint on KTN and Opinion Court on Citizen TV. A question classification scheme by Schirm [2008] was used to discuss the incidence and usage of questions in argumentative talk shows. Findings revealed that clashing, rhetorical, classic clarifying, and opinion-eliciting questions were the most frequently used types in the data sets. It was also noted that different question types served unique rhetorical purposes leading to the conclusion that argumentative talk shows on TV exhibit recursive interactional resources qualifying it as a genre

Enhancing individual animal resilience to environmental disturbances to address low productivity in dairy cattle performing in sub-Saharan Africa

The current review examines potential solutions to enhance the sustainability and productivity of the dairy sector in sub-Saharan Africa (SSA) with an emphasis on breeding for resilience. Additionally, the paper explores various indicators for measuring resilience and provides insights into the data that can be utilized to quantify resilience in SSA’s dairy production systems. Dairy production contributes significantly to food and nutritional security and employment in SSA. However, besides the general lack of enabling policy and institutional environments, production is negatively affected by environmental challenges such as high temperatures and heat stress, diseases and parasites, unreliable rainfall patterns, shortages of feeds and forages and undue preference for taurine cattle breeds regardless of their poor adaptability to prevailing local conditions. Fostering the resilience capacity of dairy animals is imperative to combat climate-related adversities and maintain productivity. This can only be achieved if reliable and practical methods for quantifying and analyzing resilience in SSA are described and undertaken. This study has reviewed variance of deviations, root mean square of deviations, autocorrelation of deviations, skewness of deviations, slope of the reaction norm and its absolute value as possible indicators of resilience in SSA. While previous research has reported genetic variation and favorable correlations of these indicators with health, fitness, and fertility traits, their potential in SSA environments requires further investigation. Besides, labor- and cost-effective phenotypic data collection is essential for characterization of resilience using these indicators. Through this study, we propose frequently collected data on milk production traits, body fat-related traits, and activity patterns as suitable in the sub-Saharan Africa context. The African Asian Dairy Genetic Gains Project by the International Livestock Research Institute (ILRI) offers a valuable opportunity to collate data from diverse dairy systems in SSA for testing the potential of these indicators. Insights from this study are helpful in improving resilience of dairy animals in SSA, which would contribute to poverty alleviation, animal welfare improvement, and better preparedness in lieu of climate change in SSA.</p

Iodine status and sources of dietary iodine intake in Kenyan women and children

In 2009, the Government of Kenya adopted a mandatory iodine standard for all ediblesalt of 30-50 mg/kg with potassium iodate as a required fortificant. To assess the new standard, iodine nutrition measurements were included in the Kenya National Micronutrient Survey (KNMS) in 2011. Spot urine samples were obtained from 951 school-age children (SAC, 5 - 14y of age) and 623 non-pregnant women (NPW, 15 – 49y), together with 625 salt samples from their households. Because salt is the major dietary source of iodine as well as sodium in Kenya, sodium concentrations were measured in the same urine samples. Using the iodine and sodium data, the report introduces a novel regression technique to apportion the urinary iodine concentrations (UIC) in both survey groups to the key sources of iodine intake, namely, naturally present (native) iodine content, iodized salt in processed foods and iodized household salt. The salt iodine (SI) content in Kenya’s households (mean 40.3 mg/kg, SD 19.4 mg/kg) showed high-quality iodized salt supply. The SI content in 94.9% of households was ≥15 mg/kg. Median UIC findings in SAC (208 μg/L) and NPW (167 μg/L) indicated adequate iodine nutrition. Although variations in UIC values existed by age, gender (only in SAC), residence type, household wealth index, and region, median UIC findings were within the accepted optimum range in virtually all sub-categories. The findings do not suggest the need for change in Kenya’s universal salt iodization (USI) strategy or adjustment of the current salt iodine standard. Partitioning of UIC values by dietary sources of iodine intake in each survey group attributed ± 35% to native dietary iodine content, ± 45% to processed food and ± 20% to household salt. The UIC levels from native iodine intake alone (60.8 μg/L and 65.3 μg/L in SAC and NPW, respectively) fell below the threshold for iodine deficiency, which supports the inference that the current USI strategy in Kenya is effective in preventing iodine deficiency. The results from regression analysis indicate that the iodine intakes of SAC and NPW can be explained mainly, and in the same way, by their urinary sodium concentrations (UNaC) and the SI contents in salt from their households. The spot UNaC data do not accurately represent salt intake estimates but the mean UNaC findings may be useful for analyzing future changes in salt supply and use from efforts to reduce the salt intake of Kenya’s population.Keywords: Universal Salt Iodization, Dietary Iodine Sources, Population Iodine Status, Keny

Livestock keepers’ attitudes: Keystone of effective community-based breeding programs

Livestock keepers in southwestern Burkina Faso hold the local Lobi taurine breed, local Zebu cattle, and their crosses. Some communities in the region have begun to implement community-based cattle breeding programs (CBBPs), which involve animal tagging and recording and, potentially, also bull sharing. Based on the hypothesis that the participation of livestock keepers in CBBPs depends on their attitudes towards these programs, we used questionnaires to survey the attitudes of 125 farmers towards cattle breeding strategies and tools. Results were analyzed using principal component analysis. Farmers showed a highly positive attitude towards maintaining the features of their preferred cattle breed, but their attitudes varied substantially towards crossbreeding for breed improvement. Farmers generally agreed that performance was more important than animal appearance, and most of them were willing to cooperate with breeders’ associations but were skeptical about sharing their bulls with other farmers. The majority was reluctant to record performance data, which may be due to a capacity deficit and their confidence in being able to select the best animals based purely on phenotype. Our analysis suggests that breeders’ associations, as a key component of CBBPs, should lay down clear rules and obligations for their members from the outset. Timely consideration of farmers’ attitudes towards different breeding tools may improve their uptake and guarantee the sustainability of CBBPs

ϕ\phi meson production in dd++Au collisions at sNN=200\sqrt{s_{_{NN}}}=200 GeV

The PHENIX experiment has measured $\phi$ meson production in $d$$+$Au collisions at $\sqrt{s_{_{NN}}}=200$ GeV using the dimuon and dielectron decay channels. The $\phi$ meson is measured in the forward (backward) $d$-going (Au-going) direction, $1.2<y<2.2$ ($-2.2<y<-1.2$) in the transverse-momentum ($p_T$) range from 1--7 GeV/$c$, and at midrapidity $|y|<0.35$ in the $p_T$ range below 7 GeV/$c$. The $\phi$ meson invariant yields and nuclear-modification factors as a function of $p_T$, rapidity, and centrality are reported. An enhancement of $\phi$ meson production is observed in the Au-going direction, while suppression is seen in the $d$-going direction, and no modification is observed at midrapidity relative to the yield in $p$$+$$p$ collisions scaled by the number of binary collisions. Similar behavior was previously observed for inclusive charged hadrons and open heavy flavor indicating similar cold-nuclear-matter effects.Comment: 484 authors, 16 pages, 12 figures, 6 tables. v1 is the version accepted for publication in Phys.
