PurposeOptimal methods for communication skills training (CST) are an active research area, but the effects of CST on communication performance in objective structured clinical examinations (OSCEs) has not been closely studied. Student roleplay (RP) for CST is common, although volunteer simulated patient (SP) CST is cost-effective and provides authentic interactions. We assessed whether our volunteer SP CST program improved OSCE performance compared to our previous RP strategy. MethodsWe performed a retrospective, quasi-experimental study of 2 second-year medical student cohorts’ OSCE data in Australia. The 2014 cohort received RP-only CST (N=182) while the 2016 cohort received SP-only CST (N=148). The t-test and analysis of variance were used to compare the total scores in 3 assessment domains: generic communication, clinical communication, and physical examination/procedural skills. ResultsThe baseline characteristics of groups (scores on the Australian Tertiary Admission Rank, Undergraduate Medicine and Health Sciences Admission Test, and medicine program interviews) showed no significant differences between groups. For each domain, the SP-only CST group demonstrated superior OSCE outcomes, and the difference between cohorts was significant (P<0.01). The superiority of volunteer SP CST over student RP CST in terms of OSCE performance outcomes was found for generic communication, clinical communication, and physical examination/procedural skills. ConclusionThe better performance of the SP cohort in physical examination/procedural skills might be explained by the requirement for patient compliance and cooperation, facilitated by good generic communication skills. We recommend a volunteer SP program as an effective and efficient way to improve CST among junior medical students.
TAO – A Software Platform for Autonomous Mobile Robots

To date, different techniques of navigation for mobile robots have been developed. However, the experimentation of these techniques is not a trivial task because usually it is not possible to reuse the developed control software due to system incompabilities. This paper proposes a software platform that provides means for creating reusable software modules through the standardization of software interfaces, which represent the various robot modules.

A cattle exposure trial was carried out in an experimental cattle farm located in Galim near Ngaoundere. Observations were made from October–November 2016 and January 2017. Exposure commenced in the morning (8 h) and ended in the night (20h). The observed number of the different boophilic insect-groups was: Stomoxys (17,453), culicids (8925), Simulium (293), Chrysops (74) and Tabanus (34). Stomoxys (921.35) recorded the highest overall observed daily landing rate (ODLR) during the first survey-round (October–November 2016) and 740.85 during the second survey-round (January 2017) as compared to other hematophagous insect-groups observed. The preferred landing spots for most of the hematophagous insects were legs and belly regions, but Tabanus were also frequent around the head region. Brown colored cattle attracted Simulium, Chrysops, culicids and Stomoxys, but black animals were preferably attacked by tabanids. Cattle were mostly attacked in the overnight parks though there was no statistically significant difference (P˃0.05). Two observed daily landing peaks (8 h–10 h and 16 h–18 h) were noticed for all biting fly-groups and was influenced by weather variables. The most frequent physical defense actions against landing flies by cattle was tail flicking. Such actions differed with survey-period, micro-ecosystems and color coat of cattle. Diurnal physical defense mechanism rhythms of cattle showed that head shaking was mostly used between 10 h–12 h and 16 h–18 h, but tail flicking and foot stamping only occurred between 13 h–15 h. There was a strong positive and significant correlation (r = 0.243, P < .001) in defense reactions and fly counts.
Plot Distortion and the Construction of Suspense in the Kiswahili Detective Fiction
Ikuathu Silas Thuranira,K.W.Wamitila,Tom Olali,Evans Mbuthia 한국외국어대학교 아프리카연구소 2021 Asian Journal of African Studies Vol.- No.51
This essay explores the plot structure in the Kiswahili detective fiction with a view to finding whether plot events are narrated in a linear progression or if there are overt plot manipulations. The paper also sought to find out how suspense as a generic feature is constructed in the Kiswahili detective works under analysis. The essay is grounded on the generic and narrative theoretical approaches. This was necessitated by the need to analyse narrative elements of sequential ordering and narrative time within the boundaries of select detective works. By analyzing eight Kiswahili detective works, it has been realized that the authors cause plot distortions through anachronies, ellipsis and narrative embedments among other devices. In Suspense construction, the paper reveals that many strategies are employed such as creating a mystery around the detective character, use of setting, use of hermeneutic codes and manipulation of character’s names among other strategies. It has been discovered that the detective character in the Kiswahili detective fiction has some similarities with the Western detective character in that both have mysterious qualities such as ability to read other character’s minds and great use of logic. This portrayal facilitates the construction of suspense.
A Survey of the Growth and Development of the Detective Fiction in West Africa
Ikuathus Silas Thuranira 한국외국어대학교 아프리카연구소 2022 Asian Journal of African Studies Vol.- No.52
This paper provides a glimpse of the developmental milestones of the detective prose in West Africa. The paper traces these developments from the oral sources in the pre-historic times to the current state. To foreground the basic features of the West African detective prose, the generic theory has been utilized. Data was collected through library research by reading primary texts on West African’s detective prose while secondary data was taken from critical works such as theses and academic papers. This data was analyzed qualitatively by extracting salient features in each text. The research found out that the current status of the detective fiction in West Africa reflects Western influences on the genre. The paper too, highlights some of the factors responsible for the growth and popularity of the detective genre in the West African region. It has been discovered that apart from providing entertainment to the masses, the detective prose is a powerful tool for highlighting social, economic and political issues in the society. The researcher found out that some of the factors for the rapid growth and popularity of this genre are their use of simple plots, attractive language, the character of the detective figure among others.

This study evaluated the dietary lysine requirement by measuring the plasma free lysine concentrations in rainbow trout, Oncorhynchus mykiss after dorsal aorta cannulation. A basal diet containing 36.6 % crude protein (29.6 % crystalline amino acids mixture, 5 % casein and 2 % gelatin) was formulated to one of the seven L-amino acid based diets containing graded levels of lysine (0.72, 1.12, 1.52, 1.92, 2.32, 2.72 or 3.52 % dry diet). A total of 35 fish averaging 512 ± 6.8 g (mean ± SD) were randomly distributed into seven groups with five fish in each group. After 48 h of feed deprivation, each group of fish was fed one of the experimental diets by intubation at 1 % body weight. Blood samples were taken at 0, 5 and 24 h after intubation. Post-prandial plasma free lysine concentrations (PPlys, 5 h after intubation) of fish fed diets containing ≥ 2.32 % lysine were higher than those of fish fed diets containing ≤ 1.92 % lysine. Post-absorptive free lysine concentrations (PAlys, 24 h after intubation) of fish fed diets containing 2.32 and 3.52 % lysine were higher than those of fish fed diets containing ≤ 1.52 % lysine. The brokenline regression analysis on the basis of PPlys and PAlys indicated that the lysine requirement of rainbow trout could be 2.34 and 2.20 % in diet. Therefore, these results strongly suggested that the dietary lysine requirement based on the broken-line model analyses of PPlys and PAlys could be greater than 2.20 % but less than 2.34 % (corresponding to be 6.01 % ≤, but ≤ 6.39 % in dietary protein basis, respectively) in rainbow trout. Also, these results shown that the quantitative estimation of lysine requirement by using PPlys and PAlys could be an acceptable method in fish.
