description: In today's competitive world of business, Human Resource is the main resource that gives companies take a competitive advantage. Therefore proper management of this resource is crucial for the success of an organization. More than ever, in today's climate of heightened expectations, performance appraisal system is receiving greater attention of human resource managers and decision-makers world over. They are expected to meet the interests of both employees and employers. They play multifaceted roles in setting the direction for employers regarding the decisions they take about their employees. Many organizations have moved towards making performance appraisal more effective for their decision making and holding their employees more accountable for results. As a result, employee's performance and the way they are appraised, requires greater attention. Having this in mind, the study has been conducted in Save the Children to assess the practices in the implementation of performance appraisal. The purpose of the study is to investigate the implementation process undertaken in the performance appraisal process. To undertake the study both primary and secondary data were used. A survey questionnaire with five points Likert scale is a main tool for gathering primary data. 267 participants from the Head Office participated in filling the questionnaires. Accordingly, the data gathered were analyzed using micro soft excel and SPSS software. My finding revealed that primary purpose of performance appraisal is missing its direction of creating competitive working systems and giving balanced rewards for workers for their contributions to an organization. In the study, performance appraisal is seen to be implemented as fulfillment of criteria and not for the soul purpose PA. Employees seem to be unhappy with the current process being implemented. Thus, in order to create competitive working conditions and systems of balanced benefits for employees, performance appraisal should be understood very well particularly by Heads of and Supervisors; and, should be implemented in the desired way for the desired purposes.

description: Interleukin-1 Receptor Type II (IL-1RII) is the decoy receptor of IL-1 cytokines. It down-regulates the immune signalling pathways. There is a competitive behaviour between the IL-1RII and IL-1RI, which is the signalling receptor of the IL-1Rs family. By adopting similarities in structure and specific shared ligands, the two receptors are competing regulators of the immune response. Conformational changes of IL-1RII is a crucial factor in its ligand binding and activation. In addition, dynamics and functionality of the receptor are known to be regulated by glycosylation. Herein, all-atom Molecular Dynamics (MD) simulations were carried out to investigate the dynamics of the apo and cytokine-bound IL-1RII upon full glycosylation. Simulations showed that the IL-1RII presents two extended/active and compact/inactive conformations. Glycosylation maintains the conformation in the extended/active state. Furthermore, It was shown that IL-1 cytokine binding to IL-1RII contributes to stabilisation of the receptor. Comparison of IL-1RI and IL-1RII interaction with IL-1β at the equilibrium condition predicted that glycosylation could increase the binding possibility of IL-1RII towards its ligand. That supports preservation of the active/extended conformation by glycosylation as observed in MD simulations.

description: Conducting antimicrobial susceptibility testing (AST) in a comparable manner requires the availability of a standardized method. Organizations, such as the Clinical and Laboratory Standards Institute (CLSI) or the European Committee on Antimicrobial Susceptibility Testing (EUCAST), provide standardized protocols for a range of fastidious bacteria but not for Mycoplasma hyorhinis. We developed a broth microdilution method for testing M. hyorhinis in a standardized and harmonized way using a modified Friis broth devoid of antimicrobial or otherwise bacterial growth-inhibiting agents. The type strain M. hyorhinis DSM 25591 was chosen to establish the methodology. The antimicrobial agents of interest were doxycycline, enrofloxacin, erythromycin, florfenicol, gentamicin, marbofloxacin, tetracycline, tiamulin, tilmicosin, tulathromycin, and tylosin, tested by using commercial SensititreTM microtiter plates. In addition, the suitability of the methodology was evaluated via variation of the individual ingredients of the modified Friis broth by either using different batches or choosing other distributors. Despite these alterations, the method provided reliable results. We obtained repeatable minimal inhibitory concentrations for all six tested field isolates and the M. hyorhinis type strain. With this newly proposed method, we aim to provide an improved AST method for diagnostic laboratories and monitoring purposes with better comparability between times and countries. In addition, this new method will allow for an improvement of targeted treatments using antimicrobial agents and thereby reduce the options for resistance development.

description: Parts I-IV showed that the number of ways to place $q$ nonattacking queens or similar chess pieces on an $n\times n$ chessboard is a quasipolynomial function of $n$ whose coefficients are essentially polynomials in $q$. For partial queens, which have a subset of the queen's moves, we proved complete formulas for these counting quasipolynomials for small numbers of pieces and other formulas for high-order coefficients of the general counting quasipolynomials. We found some upper and lower bounds for the periods of those quasipolynomials by calculating explicit denominators of vertices of the inside-out polytope. Here we discover more about the counting quasipolynomials for partial queens, both familiar and strange, and the nightrider and its subpieces, and we compare our results to the empirical formulas found by Kotěšovec. We prove some of Kotěšovec's formulas and conjectures about the quasipolynomials and their high-order coefficients, and in some instances go beyond them.

description: Reuse of building components and materials is essential in order to reduce global building waste and resource depletion. Reuse can also improve residual utility for building components and materials. Selective disassembly enables such reuse. Implementation of selective disassembly planning for buildings requires accurate and correct analytical disassembly models for building archetypes, which can be provided using Building Information Modeling (BIM). However, appropriate level-of-detail (LoD) for the required BIM-based parametric disassembly models and a methodology for automatically extracting the corresponding parameters from a BIM are unknown. These knowledge gaps are addressed by developing such a methodology for the appropriate LoD. This study aims to describe and validate a methodology for determining parameters for BIM-based disassembly models to support the reuse of building components towards a circular economy in the construction industry. Taking building structures as an example, disassembly model principles for typical building parts are proposed. Then, a framework of disassembly parametric models is determined and applied for BIM. Based on this framework, a method for automatically determining the necessary parameters is developed, and the critical attributes are suggested. Finally, the disassembly parameters of BIM elements are defined and demonstrated for four case studies in order to validate the consistency and effectiveness of this method. The results indicate useful disassembly models are properly produced within a reasonable amount of time.

description: This experimental study aimed to evaluate the effects of injectable platelet-rich fibrin (i-PRF) on mucosal healing and the release of growth factors in rats. 40 rats were used; i-PRF was administered in the right buccal area while saline was injected in the left. Cytokeratin, FGF, PDGF, TGF, and VEGF expressions were determined with immunohistochemistry. Gene expressions of EGF, TGF-β, and VEGF were analysed. Epithelialization started on the 3rd day, and connective tissue maturation was more prominent in the i-PRF-applied group. Also, the releases of VEGF, EGF, TGF-β, PDGF, and FGF were higher in the i-PRF group during the 14 days. Gene expression analysis showed that changes in TGF-β at 14 days after i-PRF injection and VEGF after 21 days were statistically significant. The results of this study suggested that autologous i-PRF application enhanced the healing of oral mucosal wounds by increasing the release of growth factors for 21 days.

description: In this paper we study various aspects of the double ramification (DR) hierarchy, introduced by the first author, and its quantization. We extend the notion of tau-symmetry to quantum integrable hierarchies and prove that the quantum DR hierarchy enjoys this property. We determine explicitly the genus $1$ quantum correction and, as an application, compute completely the quantization of the $3$- and $4$-KdV hierarchies (the DR hierarchies for Witten's $3$- and $4$-spin theories). We then focus on the recursion relation satisfied by the DR Hamiltonian densities and, abstracting from its geometric origin, we use it to characterize and construct a new family of quantum and classical integrable systems which we call of double ramification type, as they satisfy all of the main properties of the DR hierarchy. In the second part, we obtain new insight towards the Miura equivalence conjecture between the DR and Dubrovin-Zhang hierarchies, via a geometric interpretation of the correlators forming the double ramification tau-function. We then show that the candidate Miura transformation between the DR and DZ hierarchies (which we uniquely identified in our previous paper) indeed turns the Dubrovin-Zhang Poisson structure into the standard form. Eventually, we focus on integrable hierarchies associated with rank-$1$ cohomological field theories and their deformations, and we prove the DR/DZ equivalence conjecture up to genus $5$ in this context.

description: The Project Management Office (PMO) has recently become a vital business unit in many organizations worldwide and is critical to the success of project management functions in many organizations. It also the new phenomena to our country project management culture. This research project has been developed with the aim of studying the project management office role and type in ethio telecom. The study conducts in-depth literature review on Project Management Office. The PMO has different roles and responsibilities, type, structure, staff numbers, and maturity level and these factors often vary between organizations depending on the needs of organization itself. The accurate identification of the PMO roles and type is important as some organizations might spend money and resources on establishing PMOs that don't satisfy their needs and requirements. To achieve the objectives of this research, a mixed research methodology that involved mixed approaches have been used studying the existing ethio telecom PMO roles, type, structure and maturity. The data collection uses semi-structured interview questions and questionnaires as a primary data gathering sources and organizational documents and reports as secondary data sources. The outcomes of this research show that ethio telecom needs significant modifications and designs to its project management office and its roles and type were contradicted with the concept of program/project management office. The research recommended some recommendations that might help to modifying its roles and responsibilities, staffing appropriate employees and empowering this PMO in the company and helping to achieve more projects performance enhancement

description: We analize the Berry-Keating model and the Sierra and Rodríguez-Laguna Hamiltonian within the polymeric quantization formalism. By using the polymer representation, we obtain for both models, the associated polymeric quantum Hamiltonians and the corresponding stationary wave functions. The self-adjointness condition provide a proper domain for the Hamiltonian operator and the energy spectrum, which turned out to be dependent on an introduced scale parameter. By performing a counting of semiclassical states, we prove that the polymer representation reproduces the smooth part of the Riemann-von Mangoldt formula, and introduces a correction depending on the energy and the scale parameter, which resembles the fluctuation behavior of the Riemann zeros.

Para lo anterior, se puso en marcha una entrevista estructurada conducente a obtener una descripción sobre los procesos que componen la Dinámica Familiar como la comunicación, relaciones de poder, ejercicio de autoridad, autonomía de los miembros, participación en la toma de decisiones, vínculos afectivos, distribución del trabajo doméstico, normas de convivencia y mecanismos para resolución de conflictos. Posteriormente se indagaron las manifestaciones de la violencia más recurrentes en las familias, obteniendo para cada uno de los tipos de violencia intrafamiliar los siguientes resultados: en la violencia conyugal los celos e infidelidades aparecen como principales generadores de conflicto en la pareja, y los golpes suelen ser empleados para hacer frente a los mismos. Para la violencia de género se consiguió que las actividades domésticas recaen casi en su totalidad sobre las mujeres, resaltando para el caso de los hijos se observaron diferencias en la asignación de responsabilidades de acuerdo al género. Por último, se encontró que el uso de golpes, gritos e insultos para corregir a las niñas/adolescentes y las discusiones de los padres en su presencia, suelen ser los hechos/situaciones asociados al maltrato infantil a los que se expone esta población. Finalmente se desarrollaron una serie de aportes para la intervención de Trabajo Social en el Programa Talitha Qum, partiendo de la conceptualización de los resultados obtenidos, para luego proponer unos niveles de intervención (Atención-Prevención y Promoción) que sirvieran de orientación para futuros abordajes.

description: Activity of most comets near the Sun is dominated by sublimation of frozen water, the most abundant ice in comets. Some comets, however, are active well beyond the water-ice sublimation limit of ~3 AU. Three bodies dominate the observational record and modeling efforts for distantly active comets: the long-period comet C/1995 O1 Hale-Bopp and the short-period comets (with Centaur orbits) 29P/Schwassmann Wachmann 1 and 2060 Chiron. We summarize what is known about these three objects emphasizing their gaseous comae. We calculate their CN/CO and CO2/CO production rate ratios from the literature and discuss implications. Using our own data we derive CO production rates for all three objects, in order to examine a correlation between gas production and different orbital histories and/or size. We find that orbital history does not appear to play a significant role in explaining 29P's CO production rates. 29P outproduces Hale-Bopp at the same heliocentric distance, even though it has been subjected to much more solar heating. Previous modeling work on such objects predicts that 29P should have been de-volatilized over a fresher comet like Hale-Bopp. This may point to 29P having a different orbital history than current models predict, with its current orbit acquired more recently. On the other hand, Chiron's CO measurements are consistent with it being significantly depleted over its original state, perhaps due to increased radiogenic heating made possible by its much larger size or its higher processing due to orbital history. Observed spectral line profiles are consistent with development and sublimation of icy grains at about 5-6 AU for 29P and Hale-Bopp, and this is probably a common feature in distantly active comets, and an important source of volatiles for all comets within 5 AU. In contrast, the narrow CO line profiles indicate a nuclear, and not extended, origin for CO beyond ~4 AU.

description: The present work reports the physicochemical interaction between DNA and 1,8-napthalimide drugs to enlighten the field of drug discovery. Molecular dynamic studies of 1,8-napthalimide interacted DNA revealed distortions and destabilisation of the DNA. Among the drugs (Amonafide Azonafide and NNM-25), NNM-25 is found to have a strong interaction with DNA in gas and water phases by using the ONIOM method by investigating deformation and interaction energies. The reason for the higher interaction energy is attributed to the higher deformation of DNA during the interaction with NNM-25. Furthermore, the complex is investigated by the quantum chemical method to find the detailed observation of the direct Interaction of the 1,8-napthalimides with the DNA base pairs. NBO analysis is done to understand the charge transfer mechanism of 1,8-napthalimides’ interacted DNA and also it is observed that highly stabilised complexes are found to have the highest interaction energies. The density functional theory is used to calculate the chemical reactivity and site selectivity of the molecular system to explore the results that may call for further experimental studies.

description: Khintchine's theorem is a classical result from metric number theory which relates the Lebesgue measure of certain limsup sets with the convergence/divergence of naturally occurring volume sums. In this paper we ask whether an analogous result holds for iterated function systems (IFSs). We say that an IFS is approximation regular if we observe Khintchine type behaviour, i.e., if the size of certain limsup sets defined using the IFS is determined by the convergence/divergence of naturally occurring sums. We prove that an IFS is approximation regular if it consists of conformal mappings and satisfies the open set condition. The divergence condition we introduce incorporates the inhomogeneity present within the IFS. We demonstrate via an example that such an approach is essential. We also formulate an analogue of the Duffin-Schaeffer conjecture and show that it holds for a set of full Hausdorff dimension. Combining our results with the mass transference principle of Beresnevich and Velani \cite{BerVel}, we prove a general result that implies the existence of exceptional points within the attractor of our IFS. These points are exceptional in the sense that they are "very well approximated". As a corollary of this result, we obtain a general solution to a problem of Mahler, and prove that there are badly approximable numbers that are very well approximated by quadratic irrationals. The ideas put forward in this paper are introduced in the general setting of IFSs that may contain overlaps. We believe that by viewing IFS's from the perspective of metric number theory, one can gain a greater insight into the extent to which they overlap. The results of this paper should be interpreted as a first step in this investigation.

description: We develop a new Bayesian approach to estimate noncommon structural breaks in panel regression models. Any subset of the cross-section may be hit at different times within a break window. Break-specific parameters are learned from the cross-section. They reflect whether (i) breaks hit many or few series and (ii) there is a long or short lag between the first and final series hit by a break. In an empirical application to international stock return predictability, the method generates significantly more accurate forecasts than several benchmarks that yield economically meaningful utility gains for a risk averse investor with power utility.

Year: 2019

description: The objective of this research paper is to provide a better understanding of how event marketing is implemented and to test the influence of favorable disposition toward events on customer purchase behavior. In order to answer the questions non-probability sampling specifically purposive sampling technique was used. Both quantitative and qualitative methods were used. But it was more qualitative nature. Closed ended questions distributed to 384 customers and open ended question to the marketing manager and personnel's of the company. The closed ended question aimed to test the influence of favorable disposition toward events on customer purchase behavior while the open ended questions aimed to answer about objective, selection, evaluation and advantages and disadvantages of event marketing. The results revealed that favorable disposition toward events have positive and significant relationship on customer purchase behavior since it allows customers to have an experience and creates impulses to act and with regards to the objectives of using event marketing strengthening the existing image, identifying the company and brand/ product with the target audience and achieving media coverage are very important. When it comes to selection of events, companies use different criteria to select a specific event. The advantage of using event marketing is offering interaction which results in generating awareness and influencing image. The major disadvantage was lack of standardized solution and the difficulty to measure the effectiveness. Based on the findings the major recommendations were, the company should have clear objectives, use event marketing with other promotional tools, should develop their own methods to measure the effectiveness of the events and the company should create unique and entertaining events so that the customers have favorable disposition and positive experience which increases their purchase behavior

description: This study investigates the socio-economic characteristics, behavioral preferences, and consumption of individuals who own crypto-assets. Our empirical analysis utilizes data from a German personal finance management app where users connect their bank accounts and depots. We conducted a survey and elicited behavioral factors for financial decision-making. By combining survey with account and security account data, we identify crypto investors’ preferences for financial decision-making and financial advice. Our results suggest that, in particular, students or self-employed, young, and male individuals who are risk-seeking and impatient are more likely to have invested in crypto-assets. Most crypto owners have less experience with financial advisory. They see it as too time-consuming and qualitatively poor, and instead, they prefer to decide on their own as they have self-reported high financial literacy. Investigating their consumption in more detail we conclude that crypto investors more often spend on travelling, electronics, and food delivery and less on health. Our findings suggest policymakers in identifying high-risk consumers and investors, and help financial institutions develop appropriate products.

description: Background: The antiseptic agent octenidine dihydrochloride (OCT) is used for skin preparation, for Staphylococcus aureus decolonization, and within bundles for the prevention of catheter-related or surgical site infections (SSIs). Here, we review the evidence for the effects of OCT from clinical studies. Methods: Review of studies published in the Medline, Scopus, and Cochrane databases until August 2022, performed in clinical settings and reporting on effects of OCT on S. aureus carriage/transmission, SSI prevention, and prevention of intensive care unit (ICU)-related or catheter-related bloodstream and insertion site infections. Results: We included 31 articles. The success of S. aureus decolonization with OCT-containing therapies ranged between 6 and 87%. Single studies demonstrated that OCT application led to a reduction in S. aureus infections, acquisition, and carriage. No study compared OCT for skin preparation before surgical interventions to other antiseptics. Weak evidence for the use of OCT for pre-operative washing was found in orthopedic and cardiac surgery, if combined with other topical measures. Mostly, studies did not demonstrate that daily OCT bathing reduced ICU-/catheter-related bloodstream infections with one exception. Conclusions: There is a need to perform studies assessing the clinical use of OCT compared with other antiseptics with respect to its effectiveness to prevent nosocomial infections.

description: We investigate the possible existence of spin polarization and color superconductivity in the Nambu--Jona-Lasinio model with a tensor-type interaction at finite density and temperature. The thermodynamic potential is calculated by the functional integral method. Numerical results indicate that at low temperature and quark chemical potential the chiral condensed phase exists, and at intermediate chemical potential the color superconducting phase appears. In addition, depending on the magnitude of the tensor coupling, at large chemical potential and low temperature, a color superconducting phase and a spin polarized phase may coexist while at intermediate temperatures only the spin polarized phase occurs.

description: World is now at the edge of technology where the bank system is part of it using the advantage of technology towards paperless money. The main objective of this study is to identify the Challenges and Opportunities of EthSwitch E-Payment system project implementation from the perspective of the Commercial Bank of Ethiopia. Mixed research design was employed and primary data were collected through questionnaires and semi-structured interviews from management, employees and users of the system and analyzed using quantitative and qualitative methods. The finding of this study reveal that the most challenging factors to the implementation of EthSwitch Payment system is Lack of Technical support unavailability, lack of trained human resource, lack of coordination and cooperation among banks (issuer and acquirers), branches, districts and EthSwitch process is highlighted together with lack of clear legislation on consumer protection., technological and network problem specifically network failure and system failure, payment modality, security, infrastructure, foreign dependent technology, legal, regulatory issues and users' resistance to change are among the major challenges in the EthSwitch e-payment system. On the other hand, the EthSwitch E-Payment system has lots of opportunities change in the society life style though it is slow technological advancement is some of the major opportunities identified by the study and also IT infrastructure development, NBE policy direction that enforces banks to adopt technological innovation. Hence the study recommends working on addressing CBE conduct a capacity building program to its staff, work to create homogenous response and coordination in payment among issuer, acquirer for quicker response to users using the Ethswitch E-Payment, work on upgrading with knowledge and availability of its call center to offer support 24hrs a day and 7 days a week. System the network connectivity problem, quality of devices, dispute management system to deal with customer grievance and capacity building on the human resource to deal with the challenge

description: Nowadays, Blockchain Technology and Cryptocurrency have gained the attention of world media, both technological and business sectors. This study assessed the importance of implementing Cryptocurrency project in Ethiopia by collecting empirical data. "Cryptocurrency is a digital currency in which encryption techniques are used to regulate the generation of units of currency and verify the transfer of funds, operating independently of a central bank "(Cambridge Dictionary, 1995). Cryptocurrency uses the technology called Blockchain, Blockchain is a shared ledger or a continually updated list of transaction. This ledger keeps every transaction that has ever happened in a completely decentralized form and distributed among users. Because of that, third parties such as (Bank and central bank etc.) who were traditionally in charge of the ledger are no longer needed. The technology is huge, and it has applications not only in currency but in other industries such as land registration, voting and smart contracts. This study employed a case study which is used to "provide quantitative or numerical description of trends, attitudes and opinions of participants, hence participants were selected based on their knowledge and experience of the technology. The source of data were both primarily and secondary, such as, published or unpublished and public or private documents. The collected Cross-sectional data were organized and analyzed through descriptive data analysis technique so that the research can come to a conclusion and derive important information. The research finding shows the important role of Cryptocurrency and its backbone Blockchain technology to minimize the current Ethiopia's foreign currency problems and to further help the country meet its millennial development goals.

description: Finding maximum-cardinality matchings in undirected graphs is arguably one of the most central graph primitives. For $m$-edge and $n$-vertex graphs, it is well-known to be solvable in $O(m\sqrt{n})$ time; however, for several applications this running time is still too slow. We investigate how linear-time (and almost linear-time) data reduction (used as preprocessing) can alleviate the situation. More specifically, we focus on (almost) linear-time kernelization. We start a deeper and systematic study both for general graphs and for bipartite graphs. Our data reduction algorithms easily comply (in form of preprocessing) with every solution strategy (exact, approximate, heuristic), thus making them attractive in various settings.
