BIOMEDICAL ONTOLOGIES: EXAMINING ASPECTS OF INTEGRATION ACROSS BREAST CANCER KNOWLEDGE DOMAINS
Creators: name: SOJIC, ALEKSANDRA
Publisher: name: Universit� degli Studi di Milano
Year: 2013

description: The key ideas developed in this thesis lie at the intersection of epistemology, philosophy of molecular biology, medicine, and computer science. I examine how the epistemic and pragmatic needs of agents distributed across particular scientific disciplines influence the domain-specific reasoning, classification, and representation of breast cancer. The motivation to undertake an interdisciplinary approach, while addressing the problems of knowledge integration, originates in the peculiarity of the integrative endeavour of sciences that is fostered by information technologies and ontology engineering methods. I analyse what knowledge integration in this new field means and how it is possible to integrate diverse knowledge domains, such as clinical and molecular. I examine the extent and character of the integration achieved through the application of biomedical ontologies. While particular disciplines target certain aspects of breast cancer-related phenomena, biomedical ontologies target biomedical knowledge about phenomena that is often captured within diverse classificatory systems and domain-specific representations. In order to integrate dispersed pieces of knowledge, which is distributed across assorted research domains and knowledgebases, ontology engineers need to deal with the heterogeneity of terminological, conceptual, and practical aims that are not always shared among the domains. Accordingly, I analyse the specificities, similarities, and diversities across the clinical and biomedical domain conceptualisations and classifications of breast cancer. Instead of favouring a unifying approach to knowledge integration, my analysis shows that heterogeneous classifications and representations originate from different epistemic and pragmatic needs, each of which brings a fruitful insight into the problem. Thus, while embracing a pluralistic view on the ontologies that are capturing various aspects of knowledge, I argue that the resulting integration should be understood in terms of a coordinated social effort to bring knowledge together as needed and when needed, rather than in terms of a unity that represents domain-specific knowledge in a uniform manner. Furthermore, I characterise biomedical ontologies and knowledgebases as a novel socio-technological medium that allows representational interoperability across the domains. As an example, which also marks my own contribution to the collaborative efforts, I present an ontology for HER2+ breast cancer phenotypes that integrates clinical and molecular knowledge in an explicit way. Through this and a number of other examples, I specify how biomedical ontologies support a mutual enrichment of knowledge across the domains, thereby enabling the application of molecular knowledge into the clinics.

description: Background: Malaria is a major public health problem which still result in illness and death despite appropriate intervention measures being taken. Malaria can be either asymptomatic or symptomatic so, identification of such infections are very important to control malaria. Objective: To assess the prevalence of symptomatic and asymptomatic malaria infections and its associated risk factors in Debre Elias district communities, Northwest Ethiopia. Method: A community based cross-sectional study was conducted from 01 May to 30 June 2018 among selected Kebeles in Debre Elias district. A multi-stage sampling technique was carried out to select representative households. A total of 440 individuals were randomly selected from 440 households. Malaria prevalence was determined by using both light microscopy and CareStart TM Malaria HRP2/pLDH (Pf/Pv) Combo (RDT) test. Associated factors were assessed by using structured questionnaires. Data entry and analysis was done by Epi info 3.1 and SPSS version 23, respectively. The association between dependent and independent variables were explored by using bivariate and multivariate logistic regression. Statistically significant association was declared at P-value of < 0.05. Results: A total of 440 individuals were included out of which 333 were asymptomatic and 107 were symptomatic. From 333 asymptomatic participants, n=16 (4.8%, 95% CI=2.6-7.3) and n=14 (4.2%, 95% CI=2.1-6.5) were positive for malaria infection by RDT and light microscopy, respectively. Similarly, from 107 symptomatic individuals the prevalence of malaria was n=8 (7.5%, 95% CI=2.8-12.6) by both RDT and light microscopy. Overall prevalence of malaria was n=22 (5%, 95% CI=3-7) by light microscopy with the majority of infection (59.1%) caused by P. falciparum. Utilization of ITN occasionally [AOR=4.51 (95% CI=1.21-16.79), not using ITN [AOR=5.47 (95% CI=1.04-28.5)], house with eave [AOR=3.35(95% CI=1.02-10.93)], previous history of malaria infection and family history of malaria infection [AOR=3.87 (95% CI=1.1013.61)] were identified as a risk factor for malaria infection in the study area (P <0.05). Almost prefect measure of agreement was observed between RDT and light microscopy (Kappa value =0.954). Conclusion: The findings indicate that malaria remains an important public health problem in Debre Elias district. Further studies needs on the burden of malaria using more sensitive methods such as PCR to scale up the eradication and control program of malaria.

description: We show that density spikes begin to form from dark matter particles around primordial black holes immediately after their formation at the radiation-dominated cosmological stage. This follows from the fact that in the thermal velocity distribution of particles there are particles with low velocities that remain in finite orbits around black holes and are not involved in the cosmological expansion. The accumulation of such particles near black holes gives rise to density spikes. These spikes are considerably denser than those that are formed later by the mechanism of secondary accretion. The density spikes must be bright gamma-ray sources. Comparison of the calculated signal from particle annihilation with the Fermi-LAT data constrains the present-day cosmological density parameter for primordial black holes with masses $M_{\rm BH}\geq10^{-8}M_\odot$ from above by values from $Ω_{\rm BH}\leq1$ to $Ω_{\rm BH}\leq10^{-8}$, depending on $M_{\rm BH}$. These constraints are several orders of magnitude more stringent than other known constraints.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Background: The prevalence of H. pylori infection mainly acquired during childhood and may be persisting throughout life and it has been found high in developing countries; this prevalence is related to low socioeconomic status, and Intestinal parasitic infections are among the major public health problems in Sub-Saharan Africa. Their distribution is mainly associated with poor personal hygiene, environmental sanitation and limited access to clean water. There is limited information on the burden of the H. pylori and intestinal parasites in Ethiopia and this research will address such gap. Objectives: To assess the prevalence of Helicobacter pylori and intestinal parasite and their associated risk among Elementary School Children. Methods: A cross sectional study was conducted to determine the burden and risk factors associated of H. pylori and intestinal parasite among in 422 school children. The study was conducted between March to June 2017. Multiple sampling methods were used, to collect the data. The stool samples were tested for intestinal parasite using direct wet mount and concentration techniques and stool antigen test for H. pylori. Information from the laboratory analysis and questionnaires were entered into SPSS version.20 for analysis. Results: A total of (n=422) students have been participated in this study 55.2 %( n=233/422) 44.8% (n=189/418) were female and male respectively. Age of range (4-18) years, with mean age of 11.16±SD years [95% CI 10.82-11.5], the mean weight of 30.99 ± SD Kg [95 % CI 29.9 -32.08], the mean height 1.36 ± SD m [95% CI 1.34-1.38], Helicobacter pylori antigens were detected in 14.6% (n=61/422) ,and 6%(n=25/189) 8.6%(n=36/233) male and female respectively. Intestinal parasite were detected in 23.7 %( n=100/422), 10.4 %( n=44/189) 13.3 %( n=56/422) male and female respectively. The co-infection for HP and IPI was present in 4.5 %( n=19/422). The age of study subject, educational status/ monthly income status of their family/guardians, overcrowding and some sanitary practice were a risk factor for the development of intestinal parasite and H. pylori infection. Conclusions: The prevalence of H. pylori infection is 14.6 %, and IPI is 23.7 %, this burden of IPI among school children call mass de-worming which is going on in some schools. Moreover further studies are required to understand the role of HP and IPI on the overall growth of children and school performance.

Sequential multi-objective target value optimization

description: In engineering processes the specification of optimization targets is usually reduced to minimization or maximization problems. The specfication of challenging multivariate target structures is excluded, due to the lack of algorithms that are able to handle them. Often however the optimum is a precise target instead of a minimum or maximum and it would be helpful if the deviation from the target could be penalized asymmetrically. In this thesis a new heuristic named mtEGO for multi-objective target value sequential optimization has been developed. A small initial spacefilling design is used to fit a surrogate model for each objective of the optimization problem. Based on the predictions and prediction errors of the surrogate model for the whole parameter space virtual observations with dfferent (1 ..ff) confidence levels are constructed. These virtual observations are used to roughly simulate the effect of the model uncertainty on the capability of each setting in the parameter space to be the global optimum. A transformation with desirability functions and the aggregation to a joint desirability index turns the multi-objective target value prob- lem in a simple single-objective maximization problem. Improvements are determined for this single-objective maximization problem then, which are maximized tofind the global optimum. mtEGO therefore works in a hybrid way, which means for each combination of (1...ff) confidence levels an own candidate for the global optimum is determined simultaneously. The candidates are reduced to a small number of updating points using hierarchical clustering. Finally, the model is refined with the observations from the updating points and the algorithm proceeds to generate and add new updating points until the stopping criterion is fulfilled. The mtEGO algorithm is validated successfully by means of extensive simulation studies and two case studies from mechanical engineering. Beside the fact that the two case studies demonstrate the applicability of mtEGO to real applications, they show that mtEGO even works successfully if basic conditions change in an ongoing optimization process. Further, an improved variant of mtEGO, named mtEGOimp, is developed. It does a pre-selection of reasonable confidence levels before cross-combining them. As a consequence, the computation time of the mtEGO approach is strongly reduced, which relaxes time limitations. The incorporation of a convex hull restriction method for failure points and an imputation of missing values into the mtEGO approach, finally extends it to a powerful tool for optimization problems even in the presence of unknown constraints.

description: We present the results of ALMA spectroscopic follow-up of a $z=6.765$ Lyman-$α$ emitting galaxy behind the cluster RXJ1347-1145. We report the detection of [CII]158$μ$m line fully consistent with the Lyman-$α$ redshift and with the peak of the optical emission. Given the magnification of $μ=5.0 \pm 0.3$ the intrinsic (corrected for lensing) luminosity of the [CII] line is $L_{[CII]} =1.4^{+0.2}_{-0.3} \times 10^7L_{\odot}$, which is ${\sim}5$ times fainter than other detections of $z\sim 7$ galaxies. The result indicates that low $L_{[CII]}$ in $z\sim 7$ galaxies compared to the local counterparts might be caused by their low metallicities and/or feedback. The small velocity off-set ($Δv = 20_{-40}^{+140} \rm km/s$) between the Lyman-$α$ and [CII] line is unusual, and may be indicative of ionizing photons escaping.

Chiral optical fields: A unified formulation of helicity scattered from particles and dichroism enhancement
Creators: name: Nieto-Vesperinas, Manuel
Publisher: name: arXiv
Year: 2016
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: We establish a general unified formulation which, using the optical theorem of electromagnetic helicity, shows that dichorism is a phenomenon arising in any scattering -or diffraction- process, elastic or not, of chiral electromagnetic fields by objects either chiral or achiral. It is shown how this approach paves the way to overcoming well-known limitations of standard circular dichroism, like its weak signal or the difficulties of using it with magnetodielectric particles. Based on the angular spectrum representation of optical fields with only right circular or left circular plane waves, we introduce beams with transverse elliptic polarization and posessing a longitudinal component. Then our formulation for general optical fields shows how to enhance the extinction rate of incident helicity, (and therefore the dichroism signal), versus that of energy of the light scattered or emitted by a particle, or viceversa.

description: Gravitational Waves (GW) have now been detected from stellar-mass black hole binaries, and the first observations of GW from Massive Black Hole (MBH) Binaries are expected within the next decade. Pulsar Timing Arrays (PTA), which can measure the years long periods of GW from MBHB, have excluded many standard predictions for the amplitude of a stochastic GW Background (GWB). We use coevolved populations of MBH and galaxies from hydrodynamic, cosmological simulations ('Illustris') to calculate a predicted GWB. The most advanced predictions so far have included binary hardening mechanisms from individual environmental processes. We present the first calculation including all of the environmental mechanisms expected to be involved: dynamical friction, stellar 'loss-cone' scattering, and viscous drag from a circumbinary disk. We find that MBH binary lifetimes are generally multiple gigayears, and only a fraction coalesce by redshift zero. For a variety of parameters, we find all GWB amplitudes to be below the most stringent PTA upper limit of $A_{\textrm{yr}^{-1}} \approx 10^{-15}$. Our fairly conservative fiducial model predicts an amplitude of $A_{\textrm{yr}^{-1}} \approx 0.4\times 10^{-15}$---less than a factor of three below the current limit. At lower frequencies, we find $A_{0.1\,\textrm{yr}^{-1}} \approx 1.5\times 10^{-15}$ with spectral indices between $-0.4$ and $-0.6$---significantly flatter than the canonical value of $-2/3$ due to purely GW-driven evolution. Typical MBHB driving the GWB signal come from redshifts around $0.3$, with total masses of a few times $10^9\,M_\odot$, and in host galaxies with very large stellar masses. Even without GWB detections, our results can be connected to observations of dual AGN to constrain binary evolution.

description: We present an open-source and validated chemical kinetics code for studying hot exoplanetary atmospheres, which we name VULCAN. It is constructed for gaseous chemistry from 500 to 2500 K using a reduced C-H-O chemical network with about 300 reactions. It uses eddy diffusion to mimic atmospheric dynamics and excludes photochemistry. We have provided a full description of the rate coefficients and thermodynamic data used. We validate VULCAN by reproducing chemical equilibrium and by comparing its output versus the disequilibrium-chemistry calculations of Moses et al. and Rimmer & Helling. It reproduces the models of HD 189733b and HD 209458b by Moses et al., which employ a network with nearly 1600 reactions. We also use VULCAN to examine the theoretical trends produced when the temperature-pressure profile and carbon-to-oxygen ratio are varied. Assisted by a sensitivity test designed to identify the key reactions responsible for producing a specific molecule, we revisit the quenching approximation and find that it is accurate for methane but breaks down for acetylene, because the disequilibrium abundance of acetylene is not directly determined by transport-induced quenching, but is rather indirectly controlled by the disequilibrium abundance of methane. Therefore, we suggest that the quenching approximation should be used with caution and must always be checked against a chemical kinetics calculation. A one-dimensional model atmosphere with 100 layers, computed using VULCAN, typically takes several minutes to complete. VULCAN is part of the Exoclimes Simulation Platform (ESP; http://www.exoclime.net/) and publicly available at http://github.com/exoclime/VULCAN .

Seroprevalence and Risk Factors of Hepatitis E Virus Infection among Pregnant Women in Selected Health Facilities of Addis Ababa, Ethiopia
Creators: name: Abebe, Meseret
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Background: Hepatitis E virus (HEV) is highly endemic in several African countries with high mortality rate among pregnant women. The prevalence of antibodies to HEV in Ethiopian pregnant women is not known. This study aimed to assess the prevalence of anti-HEV IgG and anti-HEV IgM among pregnant women seen between April 2014 to January 2015 in Gandhi Memorial Hospital and four selected Health centers in Addis Ababa, Ethiopia. Material and methods: A total of 386 serum samples were collected from pregnant women. All pregnant women socio demographic characteristics were collected using a structured questionnaire form. Serum samples were examined for anti-HEV IgG and anti- HEV IgM using ELISA. The association of anti-HEV status with risk factors was assessed. Factors demonstrating significant association in bivariate analysis were included in multivariate logistic regression models. Analyses were performed using SPSS version 21. Results: From 386 women, 122 (31.6%) cases were positive for anti- HEV IgG and two women (0.5%) were anti-HEV IgM positive. Age and educational had statistically significant association with HEV infection. There was no significant association between anti-HEV antibody seroprevalence rate with trimester, parity, HIV status and other risk factors. Conclusion: Conclusion: This study found a high seroprevalence rate of anti-HEV IgG among pregnant women in Addis Ababa Ethiopia. Preventive measures like improvement of education in personal and public hygiene may reduce the risk in pregnant women. Moreover nationwide surveillance of HEV especially in rural setting should be conducted to establish a national estimate and validate our findings.

description: The potential of using Chat GPT and AI to revolutionize the way we interact with computers, specifically in the field of medical diagnostics. Chat GPT can make conversations between doctors and patients more natural, while AI can analyze vast amounts of patient data to identify trends and estimate a patient’s health. Patients can use Chat GPT to better understand their medical conditions, and both Chat GPT and AI can be used to automate tasks such as scheduling appointments and processing test results. However, there are limitations to using AI, including data bias, complex results, and analysis errors. To reduce errors, it is important to validate findings using various techniques and ensure that data is accurate and up-to-date. Chat GPT also employs security measures to protect patient data privacy and confidentiality.

description: We examine some of the roots of parity violation for gravitons and uncover a closely related new effect: correlations between right and left handed gravitons. Such correlators have spin 4 if they involve gravitons moving along the same direction, and spin zero for gravitons moving with opposite directions. In the first case, the most immediate implication would be a degree of linear polarization for the tensor vacuum fluctuations, which could be seen by gravity wave detectors sensitive enough to probe the primordial background, its degree of polarization and anisotropies. Looking at the anisotropy of the gravity waves linear polarization we identify the parity respecting and violating components of the effect. The imprint on the CMB temperature and polarization would be more elusive, since it averages to zero in the two-point functions, appearing only in their cosmic variance or in fourth order correlators. In contrast, spin zero correlations would have an effect on the two point function of the CMB temperature and polarization, enhancing the $BB$ component if they were anti-correlations. Such correlations represent an amplitude for the production of standing waves, as first envisaged by Grishchuk, and could also leave an interesting signature for gravity wave detectors.

description: Tokamak turbulence, driven by the ion-temperature gradient and occurring in the presence of flow shear, is investigated by means of local, ion-scale, electrostatic gyrokinetic simulations (with both kinetic ions and electrons) of the conditions in the outer core of the Mega-Ampere Spherical Tokamak (MAST). A parameter scan in the local values of the ion-temperature gradient and flow shear is performed. It is demonstrated that the experimentally observed state is near the stability threshold and that this stability threshold is nonlinear: sheared turbulence is subcritical, i.e. the system is formally stable to small perturbations, but, given a large enough initial perturbation, it transitions to a turbulent state. A scenario for such a transition is proposed and supported by numerical results: close to threshold, the nonlinear saturated state and the associated anomalous heat transport are dominated by long-lived coherent structures, which drift across the domain, have finite amplitudes, but are not volume filling; as the system is taken away from the threshold into the more unstable regime, the number of these structures increases until they overlap and a more conventional chaotic state emerges. Whereas this appears to represent a new scenario for transition to turbulence in tokamak plasmas, it is reminiscent of the behaviour of other subcritically turbulent systems, e.g. pipe flows and Keplerian magnetorotational accretion flows.

description: Background: The primary responsibility of a blood transfusion service (BTS) is to provide a safe, sufficient and timely supply of blood and blood products so as to ensure that blood donation causes no harm to the donor. The Copper Sulphate (CuSO4) screening test has been found to erroneously include anemic people and exclude eligible people and its performance is not well studied in poor settings like Ethiopia. Objectives: To determine the rate of false deferral and false pass of prospective blood donors screened by the copper sulphate gravimetric test from April to June 2016 at Hossana blood bank, Ethiopia.. Methods: A cross- sectional study was carried out from April to June 2016 in Hossana blood bank. Blood sample from 422 voluntary donors were collected and analyzed by CuSo4 gravimetric test and automated hematology analyzer (Cell-dyn 1800). The data was entered in Epi-Data 3.1 and analyzed by SPSS 20 and interpreted accordingly. P value less than 0.05 was considered as statistically significant. Agreement between the two methods was determined using the Kappa coefficient. Result: The overall deferra1 rate was 20.1% by the reference method and varies by blood collection site for the copper sulphate method (15.4% and 16.8% using capillary and whole blood, respectively). False pass rates were 9.2% and 7.6% and false fail rates were 4.5% and 4.3% using capillary and venous blood samples, respectively. The CuSo4 method using capillary blood sample had sensitivity of 94.4%, specificity 54.1%, PPV 89.1% and NPV 70.8%, while using venous blood sample it gave sensitivity of 94.7%, specificity 62.4%, PPV 90.9% and NPV 74.6%. The CuSo4 method had moderate with Kappa value of 0.53, (95% CI, 0.425-0.625, P<0.01) and substantial (Kappa value of 0.61, 95% CI (0.507 to 0.698), (P<0.01.) level of agreement with the reference method using capillary and venous blood samples, respectively. Conclusion: The high rate of false pass warrants the search for an alternative simple method to replace the old copper sulphate method. Until replaced, CuSO4 method which moderately agrees with the reference method can be retained as a primary screening tool by applying strict quality control method.

description: Abstract: The legacy of the racist Apartheid system in South Africa remains a defining feature of the university education sector in general and in particular in those universities which used to be categorised as historically disadvantaged. This article focuses on the case of universities which are still characterised asthe third and lower band university in order to problematise the issue of position and practice about corporate governance and leadership. An argument is advanced that corporate governance in general and the particular code of the King IV Report need to be critiqued beyond the de-ontologised positions and self-referential explanations about the social world, that is, the principles that the KIV Report espouses. The structural systems of role, duties and responsibilities of corporate ethical practices and sustainable value creation, for example, need to be dislodged from the required value systems for such codes if corporate governance and leadership are to transcend the enduring challenge of social systems, which tend to be self-reproductive of the status quo. Corporate governance, as it were, cannot be treated as the proxy to the actual university transformation project. What ought to matter is not just the significance of the corporate governance codes but the characters and the assumed trajectories thereof. In order to effectively manage the dynamics of corporate governance, which tend to result in unintended consequences of structural stems, the article suggests a focus on the study of corporate governance codes as systems. Such an exploratory approach can surface what seem to be the inherent contradictions of corporate governance practices especially in context of historical disadvantage. The potential danger in the understudy of corporate governance is therefore at two points. Firstly, the default position about how the University is performing as compliant to the national reporting requirements, especially at strategic level where the reported data tends to be aggregated, when, in actual fact, the disaggregated data indicates otherwise. Secondly, the fault consciousness by the members of management, leadership and governance in ways that can perpetuate historical disadvantage.

description: Research slides presented at the Operational Research Society joint Simulation and Health Special Interest Group 2023 We present a simple framework to support sharing of executable healthcare discrete-event simulation models in python over the web. Our sharing framework is based on combining remote version control repositories with free and open source software - Jupyter Notebooks, Jupyter Books, and streamlit - along with free digital infrastructure provided by Binder, streamlit.io, GitHub pages, and open science repositories such as Zenodo. The framework enables executable models to be shared with users of different technical abilities: from coders to software literate users. We provide an applied example including a full web application of an executable model. Our framework aims to support NHS organisations to preview, validate, and use models. Academic research teams can also benefit from enhanced scrutiny of their work and long term archiving of models.

description: We review recent developments of the statistical properties of complex atomic spectra, based on the pioneering work of Claire Bauche-Arnoult and Jacques Bauche. We discuss several improvements of the statistical methods (UTA, SOSA) for the modeling of the lines in a transition array: impact of high-order moments, choice of the distribution (Generalized Gaussian, Normal Inverse Gaussian) and corrections at low temperatures. The second part of the paper concerns general properties of transition arrays, such as propensity rule and generalized J-file sum rule (for E1 or E2 lines), emphasizing the particular role of the G1 exchange Slater integral. The statistical modeling introduced by J. Bauche and C. Bauche-Arnoult for the distribution of the M values (projection of total angular momentum J) in an electron configuration, written P(M), was extended in order to account for configurations with a high-l spectator and a new analytical formula for the evaluation of the number of E1 lines with a wider range of applicability was derived.

description: We predict a new class of three-dimensional topological insulators (TIs) in which the spin-orbit coupling (SOC) can more effectively generate a large band gap at $Γ$ point. The band gap of conventional TI such as Bi$_2$Se$_3$ is mainly limited by two factors, the strength of SOC and, from electronic structure perspective, the band gap when SOC is absent. While the former is an atomic property, we find that the latter can be minimized in a generic rock-salt lattice model in which a stable crossing of bands {\it at} the Fermi level along with band character inversion occurs for a range of parameters in the absence of SOC. Thus, large-gap TI's or TI's comprised of lighter elements can be expected. In fact, we find by performing first-principle calculations that the model applies to a class of double perovskites A$_2$BiXO$_6$ (A = Ca, Sr, Ba; X = Br, I) and the band gap is predicted up to 0.55 eV. Besides, more detailed calculations considering realistic surface structure indicate that the Dirac cones are robust against the presence of dangling bond at the boundary with a specific termination.

The Islands of Sanity in the Killing Fields of Inequalities: A juxtaposed case in Management, Leadership and Governance Practices! Peer- Reviewed Proceedings

description: Abstract: This article was motivated by the conversations which ensued at ECMLG 2021 after a presentation on a similar topic. The question from the audience was whether the researcher and analyst still had tenure in the insider research project he had just shared. The response was in the affirmative, although serious concerns were expressed about the quality of the tenure, symbolized by the brutality and dehumanising tendencies of the then University Regime. Therefore, this project-based article at ECMLG 2022 continues from that debate. Mirrored on the national events as a result of the Justice Zondo Commission about State Capture in South Africa, the article focuses on one case of a university institution, which was arguable under a capture during a particular regime of a Vice Chancellor and Principal. The case of “The Killing Fields of Inequalities” is very typical of the national contexts, which is still steeped in settler colonialism and in a structured racist system, strangely almost thirty years into constitutional democracy. Such a case is juxtaposed with what can be referred to as “Islands of Sanity”! The two African folklore illustrate the case as reported in the article. Firstly, that the system can be changed but it will first try to eat you up! Secondly, that when the hyena wants to eat its own children, it first accuses them of smelling like rats. Therefore, the main argument, which serves as the anchor for the article, is to problematise the taken for granted claims about management, leadership and governance practices in university education spaces. This can be done by means of realist oriented scholarship projects, which ought to dig deeper than what appears on surface as leadership for the idea of university education as the public good. In this regard, the article suggests a realist social program, which is anchored on the critical realist philosophy, in accounting for the cited practices and in ways that can shed more light for the transformative outcomes than those reported in the article. It is envisaged that the article will have as the result, promotion of systemic conversations about the default position and fault consciousness in the idea of university education in general and how such an idea should be better managed, led and governed in the national development plans (in the case of South Africa, for example).

Prevalence of Intestinal Parasites and Gastrointestinal Carriage of Gram Negative Enteric Bacteria among Apparently Healthy Food Handlers of Public Hospitals, Addis Ababa, Ethiopia
Creators: name: Belhu, Tegegn
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Background: Food borne diseases are major public health problems in developing countries like Ethiopia. Food handlers with poor personal hygiene working in hospitals could be infected with different intestinal parasites and pathogenic enteric bacteria. Therefore they could pose potential risk of transmitting food borne infection to patients and the community. Objective: To determine the prevalence of intestinal parasites and gastrointestinal carriage of pathogenic gram negative enteric bacteria among food handlers of public hospitals. Methods: Institutional based cross sectional study was conducted from March to June, 2017. Structured questionnaires were used to collect socio demographic and other related information. About 4gram of freshly passed stool specimen was collected. Direct wet mount smear examination and formol ether concentration techniques were done for detection of parasites. Culture and series of biochemical tests were done for detection and identification of pathogenic enteric bacteria respectively. Antimicrobial sensitivity test was done by Kirby-Bauer disk diffusion method. Data was analyzed using statistical package for social science. Results: In this study, 368 food handlers were participated and 81% were females. Out of 368 stool specimens 119(32.34%) were positive for at least one intestinal parasite. The most prevalent parasite was Entamoeba histolytica/dispar 48(13%), followed by Giardia lamblia 36(9.78%), Taenia Species 21(5.7%), Ascaris lumbricoide 8(2.2%), Trichuris trichiura 5(1.4%) and Hook worm 1(0.3%). Regarding enteric bacteria 17(4.6%) food handlers were positive for Salmonella 14(3.8%) and Shigella flexneri 3(0.8%). No E.coli O157:H7 was isolated. All, (n=14), Salmonella isolates were resistant to ampicillin (10μg) and erythromycin (15μg) and sensitive to Ciprofloxacin(5μg), Gentamycin(10μg) and Doxycycllin(30μg). Similarly all (n=3) Shigella flexneri isolates were resistant to ampicillin (10μg) & tetracycline (30μg) and sensitive to Cefotaxime(5μg), Ciprofloxacin(5μg), Gentamycin(10μg), Chloroamphenicol(30μg). All Salmonella and Shigella flexneri isolates were multidrug resistant. Conclusion: Strong system to provide health education and training, frequent, regular and comprehensive medical screening of food handlers could be important intervention to break the chain of infection that may arise from them.
