Year: 2017

description: This paper assessed the existing systems of early warning and early responses in the Arero district of Borna zone, Oromia regional state. The assessment was conducted based on data obtained from primary and secondary sources. The primary data were generated through focus group discussions with members of Disaster Management/Early Warning Committee at woreda and kebele levels and community elders. The secondary data were gathered from the review of secondary materials. Community level discussions were also conducted by a means of participatory assessment techniques. The study found that the most severe risks commonly prevalent in the area were drought (food insecurity) due to an acute shortage of rainfall; conflict between Borena and Geri, Borena and Guji, the Digodi and Meria in alliance with Geri against Borena and Guji over resources; and bush encroachments were also identified as threats to the livelihoods of Borena pastoralists. The pastoralist communities predict about the occurrence of risks/disasters based on the existing indigenous early warning systems. There are the Ayyaantuu who are people with knowledge of astronomy, and predict the occurrence of an event by looking into the position of stars, sun, and the moon in specific seasons. Besides, Uchuu are gifted people who can predict the occurrence of an event by reading the intestine of fresh slaughtered animal. There are indicators of risks identified by pastoralists in the existing early warning and response mechanisms based on their indigenous knowledge systems.

description: Climate change poses a serious threat to human food security through erratic rainfall patterns, increasing or decreasing temperature, decreasing crop yields and contributing to increased food insecurity. This study investigates whether men or women are more affected by climate induced household food security in rural kebeles of Dire Dawa Administration. The study also examines access and control over productive resources and the factors contributing to the differential effects of climate change on men and women household heads. A systematic random sampling procedure was employed to include 150 men and women household heads from four rural kebeles of the Administration. Standardized precipitation index and Gender disparity index on five agriculture domains such as participation in production, asset ownership and access to resource, income control, leadership and time use were used to measure the effects of rainfall intensity and productivity achievement to household food security respectively. Moreover, T-test and gender vulnerability analysis were also used to analyze the data. The results indicate that rainfall scarcity had occurred for nineteen years from the total of thirty years studied. Moreover, the mean empowerment index of women is below the threshold with differing gender division of labor in agriculture and low-calorie intake per day and more vulnerable due to effects of climate change. The findings of this study indicate the importance of enhancing institutional support to realize gender equality and minimize cultural, social, economic and institutional barriers that contribute to the differential effects of climate change on household food security.

Creators: name: Debele, Mengistu
Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2017

description: Quality of education really matters, because it has direct effect on generating productive citizens. The purpose of the study was to assess roles of HDP in professionalization of higher education instructors. It also aimed at enhancing internal quality of higher education. Semi-structured interview and non-participant classroom teaching observations were used to gather data from participants. The qualitative research method through comparative case study design was used to analyze data. The results of the current study show that HDP plays significant roles in professionalization of instructors and in enhancing internal quality of higher education. Instructors who have been certified in HDP implemented contemporary learner-centered pedagogy through constructivist approach whereas instructors who have not been certified in HDP implemented conventional teacher-centered pedagogy through behavioral approach to deliver their course contents. The study implies that HDP training should be compulsory for every instructor in higher education regardless of academic rank and experience. Furthermore, Ambo University should give due emphasis to the implementation of pedagogical skills obtained from HDP by conducting a follow-up assessment.

description: In this paper organizational factors affecting the adoption of e-learning by lecturers in Moi University were discussed and possible ways of enhancing its adoption recommended. E-learning has changed the way teaching and learning is taking place in university campuses. However, despite this change, the uptake of e-learning in developing countries especially in Africa is slow compared to their Western counterparts. The literature review also revealed that most developing countries including Kenya are still experiencing challenges in their attempts to implement e-learning as an alternative approach to teaching and learning. Descriptive research method based on a case study approach was applied. The target population of this study was 300 and sample size of 171 was used. Both inferential and descriptive statistical methods were employed in analyzing data. Findings proved that organizational factors namely professional development, access to ICT infrastructure and resources, technical support, Institutional culture, and Leadership support affect e-learning adoption by lecturers in Moi University. However, technical support and institutional culture significantly affect the adoption of e-learning by lecturers in Moi University. The main conclusion drawn from this research was that organizational factors affect e-learning adoption by lecturers in Moi University and therefore these factors should be considered in order to enhance the level of e-learning adoption by lecturers. The study recommends that Moi University management expands ICT and e-learning infrastructure, provide Lecturers with comprehensive training on e-learning skills, establish technical support staff at each department, and identify a way of motivating the lecturers to use e-learning.

description: Η Covid-19 (Coronavirus disease 2019) είναι η ασθένεια, που ξεκινώντας από την Γουχάν της Κίνας στα τέλη του 2019, κατέληξε να εξελιχθεί σε μια θανατηφόρα πανδημία, η οποία ακόμα και σήμερα πλήττει την ανθρωπότητα. Πρόκειται για μια μολυσματική ασθένεια που αναδείχθηκε ως ένα από τα σοβαρότερα ζητήματα δημόσιας υγείας τις τελευταίες δεκαετίες. Η συγκεκριμένη λοίμωξη προκαλείται από έναν RNA ιό, τον SARS-CoV-2, ο οποίος ανήκει στην οικογένεια των κορονοϊών. Οι προσπάθειες ανάπτυξης εμβολίων έναντι αυτού του νέου ιού ήταν τεράστιες καθώς η ανάγκη καταπολέμησης της πανδημίας κρίθηκε επιτακτική. Ο επιστημονικός συντονισμός και η γενικότερη συνεργασία σε παγκόσμια κλίμακα υπήρξαν πρωτοφανής και οδήγησαν τελικά στον σχεδιασμό εμβολίων, πολλών διαφορετικών τεχνολογιών, με στόχο τόσο την ασφάλεια όσο και την αποτελεσματικότητα στην προσπάθεια αντιμετώπισης της Covid-19. Η κάθε διαθέσιμη πλατφόρμα εμβολίων αξιοποιήθηκε, το επίκεντρο όμως υπήρξε η χρήση της τεχνολογίας mRNA που οδήγησε στην ταχύτατη ανάπτυξη και κυκλοφορία του πρώτου εμβολίου από τις εταιρείες BioNTech/Pfizer. Η παρούσα διπλωματική εργασία έχει ως σκοπό την ανασκόπηση της βιβλιογραφίας αναφορικά με τα αποτελέσματα που προκύπτουν σε επίπεδο ανοσολογικής απόκρισης μετά την χορήγηση του mRNA εμβολίου των BioNTech/Pfizer σε ενήλικες με σκοπό την θωράκιση των τελευταίων απέναντι σε μια ενδεχόμενη μόλυνση από τον SARS-CoV-2
description: Covid-19 (Coronavirus disease 2019) is the disease that, starting from Wuhan, China in the end of 2019, ended up evolving into a deadly pandemic, which up to this day harms humanity. It is an infectious disease that has emerged as one of the most serious public health issues in recent years. This specific infection is caused by an RNA virus (SARS-CoV-2) belonging to the Coronavirus family. Efforts to develop vaccines against this new virus were enormous as the need to combat the pandemic was judged imperative. Scientific coordination and cooperation in general on a global scale have been unprecedented and eventually led to the design of vaccines of many different technologies aimed at both safety and efficiency in trying to tackle COVID-19. Each available vaccine platform was utilized, however, the focus was the use of mRNA technology that led to the rapid development and release of the first vaccine by BioNTech/Pfizer. The purpose of this thesis is to review the literature regarding the results obtained at the level of immune response, after the administration of the BioNTech/Pfizer mRNA vaccine to adults with the aim of shielding the latter against a possible infection by SARS-CoV-2

description: Non-cognitive factors play significant roles in academic achievement of science education. The purpose of the study entitled as academic motivation, attitude and science education achievement was to examine relationship between students’ academic motivation, attitude and achievement on science education and investigate predictive power of motivation on science achievement. The study used correlational research design. The motivated strategy for learning questionnaire (MSLQ) and attitude scales were used to gather data from participants (78 males, 22 females). Achievement data collected on biology, physics, and chemistry. Analysis of the data has indicated that academic motivation and attitude correlate significantly with each other but not with science achievement except with task value (TVA) (r = 0.24, r2 = 5.76%, p <.05, df = n1 +n2 -2= 98). Regression analysis illustrates that 9% of science achievement accounted for by task value (TVA). Overall, there are low to moderate relationship between motivation and science achievement. It recommends giving high task value to science education, developing science self-efficacy, and not to develop amotivation. The study has offered the implication that science education policy and strategy designers, teachers and parents should encourage natural science students.

description: In this paper, we couple regularization techniques of nondifferentiable optimization with the h-version of the boundary element method (h-BEM) to solve nonsmooth variational problems arising in contact mechanics. As a model example we consider the delamination problem. The variational formulation of this problem leads to a hemivariational inequality (HVI)with a nonsmooth functional defined on the contact boundary. This problem is first regularized and then discretized by a h-BEM. We prove convergence of the h-BEM Galerkin solution of the regularized problem in the energy norm, provide an a-priori error estimate and give a numerical example.

Year: 2016
Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)

description: Radio telescopes that employ arrays of many antennas are in operation, and ever larger ones are being designed and proposed. Signals from the antennas are combined by cross-correlation. For $N$ antennas, the cost and power consumption of cross-correlation are proportional to $N^2$ and dominate at sufficiently large $N$. Here we report the design of an integrated circuit (IC) that performs digital cross-correlations for arbitrarily many antennas in a power-efficient way. It uses an intrinsically low-power architecture in which the movement of data between devices is minimized. In our design, the correlations are performed in an array of 4096 complex multiply-accumulate (CMAC) units. This is sufficient to perform all correlations in parallel for 64 signals ($N$=32 antennas with 2 opposite-polarization signals per antenna). When $N$ is larger, the input data are buffered in an on-chip memory and the CMACs are re-used as many times as needed to compute all correlations. The design has been synthesized and simulated so as to obtain accurate estimates of the IC's size and power consumption. It is intended for fabrication in a 32 nm silicon-on-insulator process, where it will require less than 12 mm$^2$ of silicon area and achieve an energy efficiency of 1.76 to 3.3 pJ per CMAC operation, depending on the number of antennas. Operation has been analyzed in detail up to $N=4096$. The system-level energy efficiency, including board-level I/O, power supplies, and controls, is expected to be 5 to 7 pJ per CMAC operation.

description: This study examined academic achievement motivation (AAM) and associated personal (age, grade, sex) and familial structural factors (intact, single, and step family background) among a sample 201 (94 males and 107 females) adolescent students in one of the peri-urban schools of east Hararghe zone (Haramaya). Data were collected through an inventory containing twenty four items being adapted from previous versions. Data were analyzed using a blend of descriptive and inferential statistical methods that were successively conducted to examining the status of AAM (one-sample t-test), ANOVA, regression analysis), and the pair-wise comparison (Scheffe test) of the three categories of family structures. Findings indicated that adolescent students had a reasonably acceptable level of AAM that was remarkably influenced by family structure compared to other personal factors. Although sex couldn’t make significant main effects, its interaction with family structure yielded significant effect on AAM in such a way that boys from intact family were found to stand in sharp contrast mainly to girls from step family background. Attempts were made to explain findings within the existing ecological and socio-cultural profile of the study area. Recommendations were also suggested to help properly addressing the gaps noted in this research.

description: We present the detection of a variable star with an $18.05$ minute period in far-ultraviolet (FUV) images of the globular cluster NGC 1851 taken with the Hubble Space Telescope (HST). A candidate optical counterpart lies on the red horizontal branch or the asymptotic giant branch star of the cluster, but it is statistically possible that this is a chance superposition. This interpretation is supported by optical spectroscopt obtained with HST/STIS: the spectrum contains none of the strong emission lines that would be expected if the object was a symbiotic star (i.e. a compact accretor fed by a giant donor). We therefore consider two other possibilities for the nature of FUV variable: (i) an intermediate polar (i.e. a compact binary containing an accreting magnetic white dwarf), or (ii) an AM CVn star (i.e. an interacting double-degenerate system). In the intermediate polar scenario, the object is expected to be an X-ray source. However, no X-rays are detected at its location in $\simeq 65$~ksec of {\em Chandra} imaging, which limits the X-ray luminosity to $L_X \leqslant 10^{32}$~erg~s$^{-1}$. We therefore favour the AM CVn interpretation, but a FUV spectrum is needed to distinguish conclusively between the two possibilities. If the object is an AM CVn binary, it would be the first such system known in any globular cluster.

description: Social media influencers (SMIs) represent a phenomenon that has increased drastically in previous years, reaching a peak since the COVID-19 pandemic. Much of previous research done involving parasocial relationship theory and consumer trust theory has been done regarding celebrities, leaving a gap in understanding influence and one's susceptibility to influence in an SMI context. Here, a series of closed-ended questions was applied to a young student cohort (N=91), and its power was evaluated using structural equation modelling, which indicated that a series of 25 questions holds the ability to measure susceptibility to SMI influence. These questions form the SUSIS Questionnaire, thereby representing a confirmed tool to measure susceptibility to SMI influence. These findings respond to a gap in marketing literature involving SMIs, showing the potential power and usefulness they hold in marketing strategies, but also serve as an alert that SMIs influence youth, presumedly both positively and negatively.

description: Mobile messaging services have gained a large share in global telecommunications. Unlike conventional services like phone calls, text messages or email, they do not feature a standardized environment enabling a federated and potentially local service architecture. We present an extensive and large-scale analysis of communication patterns for four popular mobile messaging services between 28 countries and analyze the locality of communication and the resulting impact on user privacy. We show that server architectures for mobile messaging services are highly centralized in single countries. This forces messages to drastically deviate from a direct communication path, enabling hosting and transfer countries to potentially intercept and censor traffic. To conduct this work, we developed a measurement framework to analyze traffic of such mobile messaging services. It allows to conduct automated experiments with mobile messaging applications, is transparent to those applications and does not require any modifications to the applications.

description: A plasma has been observed inside the vacuum chamber of the PSI Ring Cyclotron. This ionized gas cloud maybe a substantial contributor to several interior components having reduced lifetimes. The plasma's generation has been directly linked to the voltage that is applied to the Flat Top Cavity through visual confirmation using CCD cameras. A spectrometer was used to correlate the plasma's intensity and ignition to the Flat Top Cavity voltage as well as to determine the composition of the plasma. This paper reports on the analysis of the plasma using spectroscopy. The spectrometer data was analyzed to determine the composition of the plasma and that the plasma intensity (luminosity) directly corresponds to the Flat Top voltage. The results showed that the plasma was comprised of elements consistent with the cyclotrons vacuum interior

description: We use the Atacama Large Millimeter/submillimeter Array (ALMA) in Cycle 1 to determine spectroscopic redshifts of high-redshift dusty star-forming galaxies (DSFGs) selected by their 1.4mm continuum emission in the South Pole Telescope (SPT) survey. We present ALMA 3mm spectral scans between 84-114GHz for 15 galaxies and targeted ALMA 1mm observations for an additional eight sources. Our observations yield 30 new line detections from CO, [CI] , [NII] , H_2O and NH_3. We further present APEX [CII] and CO mid-J observations for seven sources for which only a single line was detected in spectral-scan data from ALMA Cycle 0 or Cycle 1. We combine the new observations with previously published and new mm/submm line and photometric data of the SPT-selected DSFGs to study their redshift distribution. The combined data yield 39 spectroscopic redshifts from molecular lines, a success rate of >85%. Our sample represents the largest data set of its kind today and has the highest spectroscopic completeness among all redshift surveys of high-z DSFGs. The median of the redshift distribution is z=3.9+/-0.4, and the highest-redshift source in our sample is at z=5.8. We discuss how the selection of our sources affects the redshift distribution, focusing on source brightness, selection wavelength, and strong gravitational lensing. We correct for the effect of gravitational lensing and find the redshift distribution for 1.4mm-selected sources with a median redshift of z=3.1+/-0.3. Comparing to redshift distributions selected at shorter wavelengths from the literature, we show that selection wavelength affects the shape of the redshift distribution.

description: Shell structure of low-lying neutron resonant levels in axially-symmetric quadrupole-deformed potentials is discussed, which seems analogous to that of weakly-bound neutrons. As numerical examples, nuclei slightly outside the neutron-drip-line, $^{39}_{12}$Mg$_{27}$ and $^{21}_{6}$C$_{15}$, are studied. For the lowest resonance I obtain $I^π$ = $Ω^π$ = 5/2$^{-}$ for $^{39}$Mg which is likely to be prolately deformed, while $I^π$ = $Ω^π$ = 1/2$^{+}$ may be assigned to the nucleus $^{21}$C which may be oblately deformed. Consequently, $^{21}$C will not be observed as a recognizable resonant state, in agreement with the experimental information.

description: The SIS (susceptible-infected-susceptible) epidemic model on an arbitrary network, without making approximations, is a $2^n$-state Markov chain with a unique absorbing state (the all-healthy state). This makes analysis of the SIS model and, in particular, determining the threshold of epidemic spread quite challenging. It has been shown that the exact marginal probabilities of infection can be upper bounded by an $n$-dimensional linear time-invariant system, a consequence of which is that the Markov chain is "fast-mixing" when the LTI system is stable, i.e. when $\fracβδ

description: BUTTLER, K.P. 2006: Zur Benennung der Carex polyphylla, zugleich Recherchen zur Carex guestphalica. Schlechtendalia 14: 17–24.Die von Loos befürwortete Namensänderung der Carex polyphylla in C. guestphalica wird diskutiert und als unbegründet abgelehnt. Die beiden Namen gehören, wofür eindeutig die Fruchtmerkmale sprechen, zu verschiedenen Arten und können nicht synonymisiert werden. Von C. guestphalica wurde bisher kein Originalmaterial gefunden, doch ist nach der Beschreibung die Zugehörigkeit zu C. divulsa wahrscheinlich, nicht aber zu C. polyphylla. Daher ist die von Loos vorgenommene Auswahl des Neotypus, eines Exemplars der C. polyphylla, zu verwerfen. Unabhängig von diesem Sachverhalt ist C. polyphylla Karelin & Kirilow 1841 älter als C. guestphalica Lang 1843.
description: BUTTLER, K.P. 2006: On the naming of Carex polyphylla, together with an inquiry into Carex guestphalica. Schlechtendalia 14: 17–24.The replacement of Carex polyphylla by C. guestphalica, proposed by Loos, is discussed and rejected as unfounded. Fruit characters indicate that both names do not belong to the same species und cannot be synonymized. No original material of C. guestphalica has been traced yet. Based on the descriptionthe plant probably belongs to C. divulsa, not to C. polyphylla. Therefore Loos’ selection of a specimen of C. polyphylla as neotype is to be dismissed. Independent from these facts C. polyphylla Karelin & Kirilow 1841 is the older name compared to C. guestphalica Lang 1843.

description: In this study, an attempt was made to examine the alignment of the teaching context in secondary schools in Ethiopia with a constructivist approach as emphasized in the education policy of the country. Constructivism underlies innovative approaches such as active learning, problem solving, and cooperative learning, and is often associated with quality learning outcomes. Nevertheless, it is believed that such an approach is less likely to lead to intended outcomes unless the teaching context is conducive. In light of this, by engaging teachers in a critical reflection, the alignment of their views and teaching context with a constructivist approach was examined. Data were collected from a class of 25 secondary school teachers. The results revealed that teachers have positive views about a constructivist approach to teaching and its introduction to the education system in Ethiopia. However, it is found that its realization in practice is more rhetoric than reality as the existing teaching practices are far behind the principles of constructivism. The traditional approach to teaching in which the teacher lectures and students passively listen is an established culture of teaching in schools and is unlikely to change as intended due to the overwhelmingly complex impediments to change in the education system. The students’ poor background, top-down policies and curricula, poor administrative and physical infrastructure are among the impediments that are holding back its implementation. Therefore, a supportive environment that encourages teachers to adopt the intended approach is needed as mere policy changes do not guarantee improvements at grassroots level.

description: This study assesses farmers’ perceptions of farmland productivity and land degradation, and land management practices in Habru woreda, north Wollo zone, Amhara national regional state, northern Ethiopia. The study employed survey research design. Data were gathered from 215 randomly selected sample respondents, 12 key informant interviewees, and 8 focus group discussion participants from 4 purposively selected representative kebeles based on agroecology and land degradation. Descriptive analysis was employed for the quantitative data using SPSS software version 17. Accordingly, about 36% and 34% of sample respondents perceived their farmlands’ productivity as very good and good, respectively. Land degradation was perceived by about 62.3% of sample respondents as severe and by 32.1% of them as moderate. Farmers used traditional and introduced management practices namely check dams, stone/soil bunds, application of manure, tree planting, contour ploughing and fallowing either per se or in combinations. Recently, Participatory Safety Net Program was implemented being derived by self-motivation and by incentives of the program as reported by 65.1% of 32.1% of sample respondents in the study area, respectively. Despite these endeavours, rainfall variability, land degradation, weeds and pests, delay in agricultural inputs, and traditional farming practices are reported as among major challenges of agricultural production. Therefore, it calls for demand driven interventions not only to avert short term challenges encountered by the farming community but also towards sustainable land management, poverty reduction, food security and livelihood development.

description: It has been proposed that a large population of unresolved millisecond pulsars (MSPs) could potentially account for the excess of GeV-scale gamma-rays observed from the region surrounding the Galactic Center. The viability of this scenario depends critically on the gamma-ray luminosity function of this source population, which determines how many MSPs Fermi should have already detected as resolved point sources. In this paper, we revisit the gamma-ray luminosity function of MSPs, without relying on uncertain distance measurements. Our determination, based on a comparison of models with the observed characteristics of the MSP population, suggests that Fermi should have already detected a significant number of sources associated with such a hypothesized Inner Galaxy population. We cannot rule out a scenario in which the MSPs residing near the Galactic Center are systematically less luminous than those present in the Galactic Plane or within globular clusters.

description: The purpose of this paper was to measure inequality of opportunities for children in Ethiopia. The study used secondary data from Living Standard Measurement Survey of Ethiopia, 2015. A total of 7207 sample children were considered. Human opportunity index was used to measure inequalities of opportunities for children. Dissimilarity index was used to measure inequality of opportunities. Opportunities were peroxied by access to basic services such as primary education, safe drinking water, health and nutrition. The dissimilarity index showed high inequality with value of 20.8, 12.9 and 8.4% for access to safe drinking water, health service and minimum nutrition opportunities, respectively. The coverage rates of access to opportunities were also less than other regions with respective values of 64.1, 29.8 and 22.9% for primary education, safe drinking water and health services. The human opportunity indices were also 61.5, 23.6 and 20.0% for these opportunities, respectively. Access to safe drinking water and health services were the lowest available opportunities as well as the highest inequitably distributed among children in Somali and Afar regional sates than other regions. This indicates that these regions allocate low resources to increase average access rate of these opportunities. Moreover, the existing services are distributed unfairly. These urge the government to create fair level playing field for children across the country. Increasing allocation of resources to improve the coverage rate of safe drinking water, health and education services in pastoral areas reduces in equality of opportunities among the regions.
