description: Let $T(d,r) = (r-1)(d+1)+1$ be the parameter in Tverberg's theorem, and call a partition $\mathcal I$ of $\{1,2,\ldots,T(d,r)\}$ into $r$ parts a "Tverberg type". We say that $\mathcal I$ "occurs" in an ordered point sequence $P$ if $P$ contains a subsequence $P'$ of $T(d,r)$ points such that the partition of $P'$ that is order-isomorphic to $\mathcal I$ is a Tverberg partition. We say that $\mathcal I$ is "unavoidable" if it occurs in every sufficiently long point sequence. In this paper we study the problem of determining which Tverberg types are unavoidable. We conjecture a complete characterization of the unavoidable Tverberg types, and we prove some cases of our conjecture for $d\le 4$. Along the way, we study the avoidability of many other geometric predicates. Our techniques also yield a large family of $T(d,r)$-point sets for which the number of Tverberg partitions is exactly $(r-1)!^d$. This lends further support for Sierksma's conjecture on the number of Tverberg partitions.

Creators: name: Mulugeta, Safework
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The relationship between project time management practices and project success has been examined by various researchers. This research could also be added to that collection. The study set out to unearth the relationship between project time management and project success, by defining both on the basis of time, cost and quality, and taking Bank of Abyssinia as the case study. Both primary and secondary data were used. The research employed quantitative research methods to realize the purpose of the study. Hence, a questionnaire, which was adopted from PMBOK, was devised and data were collected from 50 respondents out of the total distributed to 50 respondents. The data were analyzed using SPSS version 25. In addition, annual and quarter reports of result management office of the Bank of Abyssinia were scrutinized to compliment the responses (BoA, IT project team members, result management office staffs and staffs of IT Department). Project success indicators such as time, cost and quality were correlated to the respondent's ratings of the organization's project time management practices using Pearson's Correlation Coefficient. The results from the study show that there is a positive relationship between project success and project time management practices. The study enabled the researcher to conclude that the project time management practices are being practiced with relatively low level at the Bank of Abyssinia. Furthermore, developing and practicing project time management knowledge areas; devising procedures; carefully collecting, compiling and disseminating lessons learned from past project implementation; creating project management standards; and creating awareness among all stakeholders towards projects; strengthening the result management office's human and other resources; and providing trainings have been recommended as a means of improving project time management practices and attaining higher project success.

description: Despite its enormous empirical success, the formalism of quantum theory still raises fundamental questions: why is nature described in terms of complex Hilbert spaces, and what modifications of it could we reasonably expect to find in some regimes of physics? Here we address these questions by studying how compatibility with thermodynamics constrains the structure of quantum theory. We employ two postulates that any probabilistic theory with reasonable thermodynamic behavior should arguably satisfy. In the framework of generalized probabilistic theories, we show that these postulates already imply important aspects of quantum theory, like self-duality and analogues of projective measurements, subspaces and eigenvalues. However, they may still admit a class of theories beyond quantum mechanics. Using a thought experiment by von Neumann, we show that these theories admit a consistent thermodynamic notion of entropy, and prove that the second law holds for projective measurements and mixing procedures. Furthermore, we study additional entropy-like quantities based on measurement probabilities and convex decomposition probabilities, and uncover a relation between one of these quantities and Sorkin's notion of higher-order interference.

Could a quota system for publicly listed Australian companies assist progress towards gender equality for directors on boards? A study of principles, legislation, policies and practices
Creators: name: Bell, Sylvia
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Worldwide, significant progress towards gender equality and the rights of women have been achieved in many jurisdictions. Today, the merits of gender equality in the composition of director membership on public, private and government boards are clear. In Australia, progress continues towards gender equality on publicly listed company boards. However, although female participation has increased, gender disparities remain. There is an unacceptably low representation of women in non-executive board roles (now close to 30 per cent on listed companies in the Australian Securities Exchange 200) despite the high level of awareness—and accepted need—of redressing this imbalance. A research gap exists relating to how Australia can address this imbalance and progress to achieving board gender equality in publicly listed companies. To help us understand Australia’s options for future development, international case studies can provide a comparative context—specifically, Norway, which had introduced legislation for mandatory quotas for gender equality on boards in 2003. This research gap has prompted the research question that underpins this study: ‘Could the introduction of a quota system for publicly listed Australian companies assist progress towards gender equality for directors on boards? A study of principles, legislation, policies and practices’. This study’s methodology combines doctrinal and socio-legal research approaches. Situated in Australian domestic law, governance and policies, it is framed by the nation’s gender equality obligations under international law, such as the United Nations Universal Declaration of Human Rights and the Convention on the Elimination of All Forms of Discrimination Against Women.

The Role of Contract Administration on Project Performance: The Case of Oromia Water, Mineral and Energy Bureau
Creators: name: Hirpassa, Dandane
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The study dealt with the role of contract administration on the project performance at Oromia Regional State, specifically at Oromia Water, Mineral and Energy Bureau. The objectives of the research were to assess the contract administration planning practices and its role on managing the contracts, to assess the contribution of timely monitoring of contract implementation for the performance/success of projects and to assess the inspection practice and its contribution to get the intended project deliverables. Different literatures were assessed to show that contract administration plays a great role on the project performance and it acknowledged the contract administration role on project performance. A descriptive design was employed where both qualitative and quantitative methods were used in the study. Non-probability sampling technique was used and the targeted sample size of 35 respondents were drawn out of the 42 total population of the contract administration and construction supervision department and other participants from other functional departments. The data was collected by means of questionnaires and semi-structured interviews and analyzed using descriptive statistical techniques and SPSS package version 25 was used to process the data analysis. The research findings indicate that most of the water construction projects of OWMEB are not completed in conformity to their original plan, i.e. they usually sustain delay, termination, cost overrun or quality problems, which were emanated from poor contract administration specifically lack of contract administration plan, poor monitoring of the contract implementation, and lack and/or poor inspection of deliverables. This report recommends OWMEB to oversight the contracts critically to keep the projects on track and monitor the results constantly and to recruit more experienced and qualified staff with sufficient quantity for its contract management function.

description: In this work, we experimentally investigate the propagation of pulsed magnetostatic surface spin-wave (magnon) signals in an yttrium iron garnet (YIG) waveguide at millikelvin temperatures. Our measurements are performed in a dilution refrigerator at microwave frequencies. The excellent signal-to-noise ratio afforded by the low-temperature environment allows the propagation of the pulses to be observed in detail. The work gives insight both into low-temperature magnon dynamics in YIG and the potential application of systems of propagating magnons to solid-state quantum information processing.

An Assessment Of Stakeholders' Management Practices And Challenges: The Case Of Ethio International Footwear Cluster Cooperative Society (Eifccos)
Creators: name: Menkir, Habtewold
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: This study aims on Assessment of Stakeholders Management Practices and Challenges in the Case of EIFFCOS project. The research used descriptive research design and a mixed method of qualitative and quantitative approaches. The study also used both primary and secondary data sources. A questionnaire survey was carried out among project stakeholders project site. Thirty five question items were distributed to two hundred thirty four stakeholders; one hundred sixty eight questionnaires were received with a 71.8% response rate. While assessing stakeholders' management practice most of the participants disagree that all key stakeholders know the intended goal of the project; key stakeholders were communicated at the planning stage, expectations of stakeholders acknowledged and managed and key stakeholders share common understanding in the project. The most prevalent challenges of stakeholders management in the project among the others as per the respondents are managing cultural difference in communicating, reluctance in sharing important information, managing expectations of shareholders and creating empathy among them. Stakeholders have also influences in the success of the project directly or indirectly. The above mentioned facts have brought the project to be out of the planned time, cost, and quality and failed to satisfy the stakeholders. Finally it is recommended that Projects should be planned well in advance in terms of stakeholder management and the project management team should involve all key stakeholders in all phases of the project starting from conception up to the operation to improve the execution of the project.

description: High school students are interested in science but do not feel as engaged when learning about science in school. We believe social media has the potential to increase student interest in science with its affordances for learning. We will address this intersection of learning and social media use by creating engaging opportunities to spark interest in science. Istheam’s goal is to create a fun, educational video curriculum that is completely free and accessible to users via social media. Our videos on TikTok will foster a multi-contextual exposure to science that is based on learning theories and best practices for social media short videos. Our focus on interest and learning is informed by learning theories: Hidi & Renninger’s four phase model of interest development (2006), Brigid Barron’s learning ecology’s conjectures of learning (2006), Tamara Clegg et al’s building blocks of disposition (2014), and Saba Kawas et al’s design framework for mobile technologies to promote children’s interest in nature (2019). With appreciating science more important than ever, we aim for students to become more interested in science and increase their disposition towards science after watching and engaging with our videos. Currently, we have created and posted 8 videos on TikTok and conducted a learner study. From our preliminary data, students are interested in the videos we have made and provided valuable feedback in regards to our video style and content.

description: Enormous Ly$α$ Nebulae (ELANe), unique tracers of galaxy density peaks, are predicted to lie at the nodes and intersections of cosmic filamentary structures. Previous successful searches for ELANe have focused on wide-field narrowband surveys, or have targeted known sources such as ultraluminous quasi-stellar-objects (QSOs) or radio galaxies. Utilizing groups of coherently strong Ly$α$ absorptions (CoSLAs), we have developed a new method to identify high-redshift galaxy overdensities and have identified an extremely massive overdensity, BOSS1441, at $z=2-3$ (Cai et al. 2016a). In its density peak, we discover an ELAN that is associated with a relatively faint continuum. To date, this object has the highest diffuse Ly$α$ nebular luminosity of $L_{\rm{nebula}}=5.1\pm0.1\times10^{44}$ erg s$^{-1}$. Above the 2$σ$ surface brightness limit of SB$_{\rm{Lyα}}= 4.8\times10^{-18}$ erg s$^{-1}$ cm$^{-2}$ arcsec$^{-2}$, this nebula has an end-to-end spatial extent of 442 kpc. This radio-quiet source also has extended \civ\ $\lambda1549$ and \heii\ $\lambda1640$ emission on $\gtrsim30$ kpc scales. Note that the Ly$α$, \heii\ and \civ\ emission all have double-peaked line profiles. Each velocity component has a full-width-half-maximum (FWHM) of $\approx700 - 1000$ km s$^{-1}$. We argue that this Ly$α$ nebula could be powered by shocks due to an AGN-driven outflow or/and photoionization by a strongly obscured source.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The main aim of the study is to investigate the determinants of construction projects delay: the case of 20/80 condominium housing construction Projects, Addis Ababa. Specifically the study aimed at testing the relationship between the independent variables (Construction material availability, construction project planning, contractor's experience, supervision of work, construction financial resource) and the dependent variable (construction project delay). In conducting this, the study adopted mixed method research approach with concurrent traingulative research design. The target populations of the study are all contractors, consultants, and clients of the 20/80 condominium housing projects that are currently under way in the 15 sites of Addis Ababa making a universe of 720 to which 251 were sampled. The selection of respondents was made using snow ball sampling technique. 239 questionnaires were distributed to the contractor respondents and made key informant interviews of clients and consultants for the balance. The data obtained was analyzed using quantitative analysis techniques. Both descriptive and inferential statistics were used to see the determinants of projects delay and following that hypothesis tests were made at 5% level of significance. The result indicates that construction material, supervision of work and financial resource had the greatest influence on the delay of the project under study as the influence was significant at 1% level of significance. Based on the findings, it is recommended that the Addis Ababa Housing Development Project Office and other stakeholders should monitor the quality and timely supply of materials; monitor and supervise the supply of adequate construction materials, set proper feedback channels, manage projects conducted in its jurisdictions properly and consider the experience of constructors setting minimum standards.

description: We present an analysis of citations accrued over time by patents granted by the United States Patent and Trademark Office in 1998. In contrast to previous studies, a disaggregation by technology category is performed, and exogenously caused citation-number growth is controlled for. Our approach reveals an intrinsic citation rate that clearly separates into an -- in the long run, exponentially time-dependent -- ageing function and a completely time-independent preferential-attachment-type growth kernel. For the general case of such a separable citation rate, we obtain the time-dependent citation distribution analytically in a form that is valid for any functional form of its ageing and growth parts. Good agreement between theory and long-time characteristics of patent-citation data establishes our work as a useful framework for addressing still open questions about knowledge-propagation dynamics, such as the observed excess of citations at short times.

Assessment on Factors for Variance between Project Design and Actual Implementation: A Case of World Vision Ethiopia
Creators: name: Yihdego, Aster
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: This research investigated the factors for variance between project design and actual implementation in World Vision Ethiopia. The study was done primarily based on the analysis of data found from respondents (primary data) and other relevant information from the organization (secondary data). Descriptive survey was used as a research strategy and a non-probability judgmental sampling as sampling technique. This method helps in avoiding repetition of sample elements, increasing the representativeness of the population and to have non-biased and accurate answers from the volunteer respondents. The main findings of this research showed that World Vision Ethiopia has visible strength in its structure, systems and procedures to successfully manage its numerous projects with a significantly large amount of resource. It also revealed that the organization has a number of internal and external factors that affected its ability to manage its projects within acceptable variance limit. Finally, it is recommended that World Vision needs to develop a staff engagement and recognition policies and procedures and there should be management support throughout the project life cycle. The outcome of this research will serve World Vision Ethiopia to evaluate itself and make improvement on its weaknesses. The research also serves other organizations as a reference tool to check their performance of project management and become a better organization in a competitive environment
Curious Conversations

Publisher: name: Stanford Digital Repository
Year: 2023
Subjects: subject: Conversational Agent
subject: Science

description: It is critical to provide opportunities for young children to engage in meaningful conversations to foster long-term interest and curiosity in their topic of interest. Although many elementary school students are interested in a diverse range of science topics, they spend limited time learning about their favorite subjects at school (Sparks, 2021). Although many platforms aim to solve this problem by providing informal learning experiences for children at home, they fail to promote engagement and curiosity among our learners. 

Curious Conversations leverages voice-based agents in homes to engage learners in science-related discussions. Using our platform, children aged 8-12 years first dive into an icebreaker question that informs them what they could do in space based on their interests. Then, they read a story with their social partner, Trazo, through the Alexa device. Trazo poses questions to the child that would help them reflect. Towards the end of the story, they engage with sentimental analysis questions and a drawing activity.  Our aim is to help them gain confidence, build creativity, and eventually become independent learners. 

During our user-testing sessions, we measured children's engagement and curiosity with our prototype through the initiation and duration of their interaction, explanation of their answers, connection to prior experiences, and excitement levels while talking to Trazo. Preliminary evidence suggests that children do like interacting with a conversational agent and different age groups interact with the conversational agent differently.

Explicitly, we show that if K is a small category, V is a closed symmetric monoidal category and C is a closed V-module, then the diagram category V^K is a closed symmetric monoidal category and the diagram category C^K is a closed V^K-module. We then prove that if further K is a Reedy category, V is a monoidal model category and C is a V-model category, then with the Reedy model category structures, V^K is a monoidal model category and C^K$ is a $\mm^K-model category provided that either the unit 1 of V is cofibrant or V is cofibrantly generated.

description: The study assessed post implementation challenges of Interest Free Banking (IFB) project at Commercial Bank of Ethiopia. It was conducted based on data collected from employees of CBE through questionnaires and interview. Simple random sampling method was used to select branches and purposive sampling was used to select target respondents. For the data analysis, SPSS V.20 and descriptive data analysis method was used. Findings revealed that inadequate public awareness, scarcity of manpower, lack of Shariah advisory board, lack of Islamic insurance and lack of Islamic financial service board as post implementation challenges of IFB project that will bring adverse effect. It also revealed that the measures taken to reduce the challenges were unsatisfactory. The recommendation driven was that the Bank should conduct post implementation reviews and feedback mechanisms continuously, document lessons learned, involve Shariah advisory boards and IFSB and the government should establish Islamic insurance

description: There is an especially strong need in modern large-scale data analysis to prioritize samples for manual inspection. For example, the inspection could target important mislabeled samples or key vulnerabilities exploitable by an adversarial attack. In order to solve the "needle in the haystack" problem of which samples to inspect, we develop a new scalable version of Cook's distance, a classical statistical technique for identifying samples which unusually strongly impact the fit of a regression model (and its downstream predictions). In order to scale this technique up to very large and high-dimensional datasets, we introduce a new algorithm which we call "influence sketching." Influence sketching embeds random projections within the influence computation; in particular, the influence score is calculated using the randomly projected pseudo-dataset from the post-convergence Generalized Linear Model (GLM). We validate that influence sketching can reliably and successfully discover influential samples by applying the technique to a malware detection dataset of over 2 million executable files, each represented with almost 100,000 features. For example, we find that randomly deleting approximately 10% of training samples reduces predictive accuracy only slightly from 99.47% to 99.45%, whereas deleting the same number of samples with high influence sketch scores reduces predictive accuracy all the way down to 90.24%. Moreover, we find that influential samples are especially likely to be mislabeled. In the case study, we manually inspect the most influential samples, and find that influence sketching pointed us to new, previously unidentified pieces of malware.

description: Anxiety disorders are among the most commonly diagnosed psychological disorders in childhood. Although cognitive behavioural therapy (CBT) has demonstrated general efficacy in treating childhood anxiety, it remains unclear why nearly four out of ten young people do not respond to treatment. This study investigated a group of children and adolescents who retained one or more anxiety disorders after completing a course of CBT. Participants comprised 1509 anxious young people (5 – 18 years) whose data were collected from nine global clinical sites, with assessments at pre- and post-treatment, and at least once more at 3, 6, or 12-month follow-up. Cluster analyses were used to identify three response groups within the sample as delayed responders, relapsed responders, and non-responders. Significant predictors of these response groups included primary anxiety severity, a primary diagnosis of social anxiety disorder, comorbid anxiety disorders, and maternal psychopathology. Influential process factors included treatment delivery and intensity. Finally, growth curve models confirmed non-linear treatment response trajectories revealing distinctly different pathways of response for all groups following completion of treatment. Together, these findings enhance our ability to identify and profile a childhood anxiety treatment non-responder and may assist the future development of clinical tools which may enable clinicians to deliver the right care to the right child at the right time.

description: Current practice of the real estate industry shows that it is a rare event that the projects are completed on the scheduled time, budgeted cost, and desired quality because the construction projects experience a tremendous amount of delays. Timely completion of construction project is a major criterion of project success. The need to control the causes of delays during the construction process comes out when the number of delay project has been increasing from time to time. Hence, it is essential to identify the causes of this problem from the early stage of construction project. The objectives of this study are to study the causes of delay in term of frequency occurrence and severity effect. A total of 70 contractors and consultants with an experience in construction of private real estate project are involved in the study. A questionnaire survey was conducted to identify the significant causes of delay in order to avoid or minimize their impact on construction project. The perspective of contractors, consultants and client has been analysed and ranked based on Relative Important Index (RII). The study indicate that the top major causes of delay were ´Owner interference´, ´Frequent change orders´, ´Long waiting time for approval of tests and inspection´, ´Shortage of construction material´, ´Mistakes in design documents´, ´Inappropriate organizational structure linking all parties involved in the project´, ´Mistakes and discrepancies in design documents´, ´Discrepancies in contract document´ and ´Delays caused by subcontractors´. In addition, the top major effects of delay were; time overrun, cost overrun, dispute, arbitration, litigation and abandonment.

description: A multiphase flowmeter (MPFM) is used in the upstream oil and gas industry for continuous, in-line, real-time, oil-gas-water flow measurement without fluid separation. An MPFM typically consists of phase-fraction (holdup) and velocity (or flow rate) measurements. It is desirable to have homogeneous flow at the measurement location so that the phase-fraction measurement is representative. A horizontal blind-tee pipe-section is often installed to homogenize flow in the downstream vertical Venturi-based flowmeters; however, little information is available on the effect of horizontal blind-tee depth (HBD) on flow homogeneity. In addition, the Venturi vertical entrance length (VEL) leading to the Venturi inlet from the horizontal blind-tee outlet is another design parameter that may potentially affect the downstream phase distribution. The phase-fraction measurement principle requires liquid properties (e.g. water salinity). The local liquid richness makes the horizontal blind-tee an ideal location for measuring liquid properties; however, an excessive HBD may affect the reliability of the measurements of liquid properties, because local vortices may degrade liquid measurement representativeness if the local liquid velocity is too low. This study uses a computational fluid dynamics approach to evaluate the effect of HBD and VEL on multiphase flow measurement, including the Venturi differential-pressure, the Venturi inlet and the throat phase-fraction, and the local liquid-property at the end of a horizontal blind-tee. The computational results are validated with experimental data collected in a multiphase flow facility. Appropriate HBD and VEL are recommended.
