description: We calculate the bulk and boundary parts of the free energy for an open spin-1/2 XXZ-chain in the critical regime by bosonisation. We identify the cutoff independent contributions and determine their amplitudes by comparing with Bethe ansatz calculations at zero temperature T. For the bulk part of the free energy we find agreement with Lukyanov's result [Nucl.Phys.B 522, 533 (1998)]. In the boundary part we obtain a cutoff independent term which is linear in T and determines the temperature dependence of the boundary susceptibility in the attractive regime for $T\ll 1$. We further show that at particular anisotropies where contributions from irrelevant operators with different scaling dimensions cross, logarithmic corrections appear. We give explicit formulas for these terms at those anisotropies where they are most important. We verify our results by comparing with extensive numerical calculations based on a numerical solution of the T=0 Bethe ansatz equations, the finite temperature Bethe ansatz equations in the quantum-transfer matrix formalism, and the density-matrix renormalisation group applied to transfer matrices.

description: In order to support animal health care on pig farms a Health Planner Pigs has been developed. In 1998 the practical value of the system was tested under field condition on pig farms. The Health Planner proved to be a valuable instrument for monitoring and evaluating animal health on pig farms. Due to the promising results of the field experiment, the Dutch Farmers Organisation (LTO-Nederland) in 1999 adopted the system and coordinates its adaptation and introduction into practice. In 2001, veterinarians and farm advisers has been educated in using the Health Planner. Some parts of the Health Planner will be automised and linked to existing farm management information systems. In 2002, farmers will be educated in the use of it.

description: We develop and exploit a source of two-photon four-dimensional entanglement to report the first two-particle all-versus-nothing test of local realism with a linear optics setup, but without resorting to a non-contextuality ssumption. Our experimental results are in well agreement with quantum mechanics while in extreme contradiction with local realism. Potential applications of our experiment are briefly discussed.

Habitat-specific genetic and phenotypic differentiation in juvenile coho salmon
Creators: name: Dobson, Diana
Publisher: name: University of British Columbia
Year: 2009

description: Juvenile coho (Oncorhynchus kisutch) will spawn and have their offspring reared in very different habitat types in coastal British Columbian streams. For instance, some utilize main channel river areas whereas others take advantage of off-channel habitats. However, during winter, juveniles produced in the main channel areas are believed to move into off-channel habitats for reasons of protection. These main channel juveniles tend to be much larger at the start of winter than the off-channel resident juveniles. It is possible that these two size morphs reflect genetic differentiation that would indicate either the fine-scale population structure or heritable growth-related differences between individuals using different habitats. On the other hand, the variation may simply reflect phenotypic plasticity. There is little understanding of the correspondence between neutral molecular genetic variation and adaptive variation, yet patterns of molecular variation are most often used to develop management plans directed towards conserving genetic diversity in salmon populations. This study describes variation for both microsatellites (neutral genetic markers) and growth, presumably an adaptive trait, in closely located populations of coho salmon. The genetic basis of the observed size variation was explored by studying juvenile coho from the Mamquam River. After 6 months rearing in a common environment, no size differences were observed between juveniles originating from different habitats. More variation for size was observed between individuals sampled from within habitat types than was observed among habitats. This result suggested that the size variation is a result of phenotypic plasticity associated with environmental differences in rearing habitat. It does not exclude the possibility that variation for growth among individuals is associated with adaptive differences on a microhabitat scale. Microsatellite analysis revealed fine-scale population structure within the Mamquam River resulting from either founder effects associated with channel colonisation, the existence of separate races, or sampling bias. Heritability for growth over the six-month rearing period and size were estimated by a novel technique that uses molecular marker similarity to infer relatedness. Positive co-variances were observed between relatedness and phenotypic similarity for growth rate and initial size indicating heritability for these traits.
On the Use of Vector Spherical Harmonics

description: In many astronomical works, the structure of vector fields is analyzed, such as the differences in the celestial object coordinates in catalogs or the celestial object velocities, by decomposition into vector spherical harmonics (VSH). This method has shown high efficiency in many studies, but, at the same time, comparing the results obtained by different authors can cause difficulties associated with different approaches to building the VSH system and even with their different designations. To facilitate this task, this paper provides a comparison of the three VSH systems most often used in works on astrometry and stellar astronomy.
Understanding Quality: Examining Addis Ababa University Students’ Conceptualizations through the Harvey and Green (1993) Quality Framework
Creators: name: Ademe, Enguday
Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2023

description: As elusive and contentious as the term quality is, according to Harvey and Green (1993), there are five ways of thinking about quality in higher education that are framed as exception, as perfection, as fitness for purpose, as value for money, and as transformation. Interpretations of quality in higher education vary depending on stakeholders’ views. Among the different stakeholders, the purpose of this study was to examine students’ conceptualizations of quality interpreted through the Harvey and Green (1993) quality framework. The study was qualitative thematic in its approach, and data were collected using feedback surveys. All the one hundred and eighty five first year graduate students, who were attending their coursework in 13 different fields located in eight of the 10 colleges in Addis Ababa University (AAU), filled the survey. From these respondents, a total of 283 replies were collected. Data were then thematically analyzed using percentages. The findings revealed that students define quality differently, and the term means different things even for the same student. However, their conceptualizations converge mostly around the quality as fitness for purpose category (especially as customer-determined fitness), followed by quality as exceptional (especially as excellence) and quality as transformative categories. It is recommended that AAU’s quality-related effort, quality as understood by students, needs to primarily deal with refining its services and enhancing graduate employability. This has to be followed by taking care of student admission, teacher recruitment criteria, and bringing long-lasting qualitative changes on the part of students for life beyond the university.

description: Stellar spot distribution has consequences on the observable periodic signals in long-time baseline ground-based photometry. We model the statistics of the dominating spots of two young and active Solar-type stars, V889 Her and LQ Hya, in order to obtain information on the underlying spot distribution, rotation of the star, as well as the orientation of the stellar axis of spin.
 By calculating estimates for spot-induced periodicities in independent subsets of photometric data, we obtain statistics based on the dominating spots in each subset, giving rise to largest-spot statistics accounting for stellar geometry and rotation, including differential rotation.
 Our simple statistical models are able to reproduce the observed distribution of photometric signals rather well. This also enables us to estimate the dependence of angular velocity of the spots as a function of latitude. Our results indicate that V889 Her has a non-monotonic differential rotation curve with a maximum angular velocity between latitudes of 37-40 deg and lower angular velocity at the pole than the equator. Our results for LQ Hya indicate that the star rotates much like a rigid body. Furthermore, the results imply that the monotonic Solar differential rotation curve may not be a universal model for other solar-type stars.
 The non-monotonicity of the differential rotation of V889 Her is commonly produced in magnetohydrodynamic simulations, which indicates that our results are realistic from a theoretical perspective.

Some Notes on the Past of Oromo Society: The Story about Akkoo Manooyyee in Focus
Creators: name: Imana, Gutema
Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2023

description: This article aims to shed light on the past of Oromo society through the assessment and analysis of some oral traditions, particularly the story about Akkoo Manooyyee. The research that resulted in this article was a mix of historical, anthropological, and sociological research that was undertaken in the last five years. Descriptive and narrative research designs and a qualitative research approach were employed in the study. Data were collected from well-informed and knowledgeable informants from different parts of Oromia. In addition to oral data, relevant written sources were also consulted and used to augment the oral data. The findings of the research indicate that Oromo society had possibly been a matriarchal society for a considerable period in ancient or prehistoric times before the gradual evolution of the patriarchal system. During this matriarchal period, women seem to have been dominant socially, economically, and politically in society. It seems that Oromo society was ruled initially by women and later on by men before the gradual evolution of the Oromo Gadaa system some 5000 or more years ago.

description: Formerly a rich-county preoccupation, dealing more explicitly with environmental concerns around agriculture is becoming a mainstream concern for developing countries. Concerns arise with all the major resources underpinning farming, such as land and water which are selectively reviewed here but most attention is concentrated on the soil resource and carbon sequestration possibilities. The results of some environmental interventions constitute public goods at variously local, regional and global levels and thus provide a rationale for potential engagement for governments and development agencies.
Entangling capacity and distinguishability of two-qubit unitary operators

Subjects: subject: Quantum Physics (quant-ph)

description: We prove that the entangling capacity of a two-qubit unitary operator without local ancillas, both with and without the restriction to initial product states, as quantified by the maximum attainable concurrence, is directly related to the distinguishability of a closely related pair of two-qubit unitary operators. These operators are the original operator transformed into its canonical form and the adjoint of this canonical form. The distinguishability of these operators is quantified by the minimum overlap of the output states over all possible input probe states. The entangling capacity of the original unitary operator is therefore directly related to the degree of non-Hermiticity of its canonical form, as quantified in an operationally satisfactory manner in terms of the extent to which it can be distinguished, by measurement, from its adjoint. Furthermore, the maximum entropy of entanglement, again without local ancillas, that a given two-qubit unitary operator can generate, is found to be closely related to the classical capacities of certain quantum channels.

Discoursing Namummaa: Indigenous Philosophy of Inter-Human Relations and Peacebuilding from the Oromo People of Ethiopia
Creators: name: Wachiso, Bekalu
Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2022

description: The main thrust of this study was to discourse the Oromo indigenous philosophy of human relations, Namummaa, using the Oromo people’s conception of morality as a point of reference. Namummaa, is the Oromo philosophy of humanness that claims what makes a human being a person, not just human being, is his or her potential to grow into good and mature vertical and horizontal relationships: relationship with community in which a person lives and with other human community as the whole, and relationship with the creator and with all that is created. The study was primarily a synthesis of systematic readings of available written and oral sources from primary and secondary data. The main thesis this study has advanced is that Namummaa, according to the Oromo perspective, is complex, connected to the strong quality of human beings, meaningful in terms of building intercultural dialogue for peace building in Ethiopia and is loaded with cultural values that govern the people’s way of life. Besides, Namummaa, as the Oromo moral value, has immense functional values. This means that the administrative, justice system and economic wellbeing are developed through emboldening the moral capacity of the individuals. A morally developed person in turn stands for the collective spirit of all. This is all in one and one in all.

description: This paper presents an irrigation farm management tool, SALMOD (Salinity And Leaching Model for Optimal irrigation Development), that calculates the profit maximizing crop enterprise composition and irrigation management options for farm specific soil type, drainage status and irrigation system composition subject to various regional control measures and expected irrigation water salinities. After stating the water quality problem, and particularly salinisation in Southern Africa, the input data requirements and the results of SALMOD and their usefulness at farm level, are discussed. The impact of various possible regional or policy regulations are then discussed. SALMOD was developed for irrigators in the lower Vaal and Riet Rivers in South Africa. These farmers have been experiencing rapidly fluctuating salinity levels in their irrigation water, resulting in soil salinisation, yield loss and subsequent financial instability. SALMOD calculates the profit maximizing crop choice and distribution over the farm, matching the crop choice with soil type, drainage status and irrigation system, indicating the optimal leaching vs. yield reduction seasonal management options as well as calculate long term management options such as underground drainage installation, a change in irrigation system or the construction of on farm storage dams. Leaching is necessary to maintain an acceptable salt balance in the root-zone of irrigated crops. This however contributes to point and non-point source water pollution externalities if not managed correctly. Results show valuable policy information regarding the interactions between artificial drainage subsidisation, return flow restrictions and on-farm storage.

description: Statewide average and critical rates of accidents were determined from 1970-1972 Kentucky accident records for each type of rural highway. Four-lane undivided highways had the highest average accident rate; parkways (toll roads) had the lowest rate. The severity of accidents was related to types of accidents, highways, and traffic control and to safety belt usage. Accidents involving pedestrians were the most severe types; single-vehicle accidents ranked next highest in severity. Excluding accidents at railroad crossings, accidents which occurred on curves had the highest severity index. The use of safety belts was associated with reduced severity.

description: A universal fault-tolerant quantum computer that can solve efficiently problems such as integer factorization and unstructured database search requires millions of qubits with low error rates and long coherence times. While the experimental advancement towards realizing such devices will potentially take decades of research, noisy intermediate-scale quantum (NISQ) computers already exist. These computers are composed of hundreds of noisy qubits, i.e. qubits that are not error-corrected, and therefore perform imperfect operations in a limited coherence time. In the search for quantum advantage with these devices, algorithms have been proposed for applications in various disciplines spanning physics, machine learning, quantum chemistry and combinatorial optimization. The goal of such algorithms is to leverage the limited available resources to perform classically challenging tasks. In this review, we provide a thorough summary of NISQ computational paradigms and algorithms. We discuss the key structure of these algorithms, their limitations, and advantages. We additionally provide a comprehensive overview of various benchmarking and software tools useful for programming and testing NISQ devices.

description: Italian wine firms are facing a significant reduction in wine consumption and increasing competition in international markets. In fact, markets are becoming increasingly liberalized and producers of non-EU countries adopt even more aggressive strategies to increase their competitiveness. Nevertheless, demand for high quality wine which includes a large number of Italian wines, is increasing. The aim of this work is to explain the magnitude of the trade flows for high quality wine from Italy to its main importing countries. This objective has been reached by establishing an appropriate econometric model derived from an extended form of the "Gravity Model". This model has been broadly applied to the analysis of international trade because it provides robust estimates. Note that applications to the specific products' trade are still limited in number. The results obtained and the model itself are useful in forecasting potential trends in the exportation of high quality Italian wines. Moreover, it is possible to identify the growing markets where Italian ventures could exploit certain promotional and communication strategies. Finally, with respect to Italian high quality wine these estimates give a quantitative evaluation of the export gains that could result from the enlargement of the EU and from an increasing liberalization in international trade.
EFL Instructors’ Application of Scaffolding in Writing Lessons: The Case of Wollega University

description: The study aimed at exploring the extent to which EFL teachers scaffold their learners in the writing classrooms of Communicative English Language Skills II. To this end, a case study design in which six English instructors from Wollega University were selected purposively was used. They were video recorded while teaching writing lessons. Totally, fifteen sessions of the instructors were observed and data were taken from nine sessions. Then, the data were transcribed into text. Next, interactional episodes were separately identified and coded for contingency which involves scaffolding based on van de Pol's (2012) model of contingency teaching. The finding indicated that there was limited interaction in the writing classroom as teachers dominate the class. Besides, the interactions available in the writing classrooms were the traditional initiation-response-feedback (IRF) patterns that hinder students' learning and most of the extended interactions were characterized by short students' turns. Thus, it was concluded that teachers were not properly scaffolding the development of students’ writing. This urges teachers to give attention to the concept of scaffolding in their teaching to provide proper assistance for their learners.

description: Traffic behavior studies were conducted at seven lane-drop locations, representing three lane-drop classes. These studies consisted of conflict observations (that is, erratic movements and brakelight applications), spot-speed observations, and lane volume counts. Such a study was made before and after each different traffic control device installation in an attempt to determine which device was the most effective in minimizing conflicts at existing lane drops. A study of conflict deviations indicates that no single type of traffic control device studied was significantly effective in reducing erratic movement and brakelight rates at all seven lane-drop locations. Rather, it appears that different traffic control devices are generally most effective at each of the locations. The single-lane exit without taper constituted the lane-drop classification with the lowest conflict rates. Those lane drops with poorer sight geometries were observed to have higher conflict rates. No definitive relationship between traffic conflict rates and either volumes or accident rates was found for the lane drops studied. Certain data limitations were discovered.

description: Neutron stars change their structure with accumulation of dark matter. We study how their mass is influenced from the environment. Close to the sun, the dark matter accretion from the neutron star does not have any effect on it. Moving towards the galactic center, the density increase in dark matter results in increased accretion. At distances of some fraction of a parsec, the neutron star acquire enough dark matter to have its structure changed. We show that the neutron star mass decreases going towards the galactic centre, and that dark matter accumulation beyond a critical value collapses the neutron star into a black hole. Calculations cover cases varying the dark matter particle mass, self-interaction strength, and ratio between the pressure of dark matter and ordinary matter. This allow us to constrain the interaction cross section, $σ_{\rm dm}$, between nucleons and dark matter particles, as well as the dark matter self-interaction cross section.

description: Simulations in the GUSBAD Catalog of gamma-ray bursts suggest that the apparent duration of a burst decreases as its amplitude is decreased. We see no evidence for this effect in the BATSE catalog. We show that for a burst at the detection limit, the typical signal-to-noise ratio at the edges of the T90 duration is around 1.5, suggesting that T90 must be quite uncertain. The situation for T50 is less unfavorable. Simulations using the exact procedure to derive the durations in the BATSE catalog would be useful in quantifying the effect.

This resulted in 145 questions that developers considered relevant for data scientists to answer, thus providing a research agenda to the community. Fast forward to five years, no further studies investigated whether the questions from the software engineers at Microsoft hold for other software companies, including software-intensive companies with different primary focus (to which we refer as software-defined enterprises). Furthermore, it is not evident that the problems identified five years ago are still applicable, given the technological advances in software engineering.

description: The Arab oil embargo in mid-October 1973 curtailed availability of gasoline. Fuel conservation measures resulted in reduced travel and decreased traffic speeds. On March 1, 1974, posted speed was set at 55 mph on rural highways in Kentucky. Traffic volumes, speeds, and accidents for the rural highway during the period known as the "energy crisis" and its after effects were compared to the corresponding period a year earlier.  Traffic volumes began to decline in December 1973 but began to rise again in March 1974. Total travel in the seven months through June 1974 decreased by 3.5 percent; traffic increased by 5 percent in 1973. Accident rates during this period decreased by 13.6 percent; and the largest decreases were associated with the highways experiencing the greatest reductions in travel speed. The relationship between traffic speed and accident rate showed a great decrease in accident rate as traffic speeds decreased. Differences between wet-surface and dry-surface accident rates were especially significant and were more so for interstate than for two-lane highways. Improved wet-pavement skid resistance at the lower speeds obviously contributed to a reduction in accident rates. Continuation of the 55-mph speed limit on all rural highways would seem advisable.

description: The successful literature about gravitational models stresses that bilateral trade flows among countries is influenced by GDP factors and transaction costs. In other words the mass of bilateral trade would be related to the typical demand-supply factors which explain the quantity of traded goods in perfect competition models and a wide series of variables which express transaction costs whose role is strongly highlighted by institutional economists. If compared to the previous literature our paper shows a twofold novelty. First it is the first attempt to analyse the bilateral trade of specific agricultural goods for Italy by a cross country and panel analysis and second it provides an original specification for transaction costs. In particular, we assume that the level of organic certification standards harmonisation between Italy and extra-European countries could represent a good "proxy" for the cultural, political and social affinity in bilateral trading. Interestingly we find that the absence of specific import harmonisation rules between Italy and other extra-European countries decreases the level of bilateral trade for all the agricultural produce. A plausible explanation could be that harmonisation of organic standards is a signal of low transaction costs. In this context for a specific country the awareness of a high harmonisation level of organic standards towards another region could represent affinity in the trading activities for the whole agricultural produce. The policy agenda about the harmonisation of the agricultural standards should be tackled in the context of a more complex agenda concerning the affinity of political, cultural and social practices among different regions in the agricultural and in all the other economic sectors.

description: The Purposes of this paper are twofold (i) to evaluate changes in welfare gains and their distribution due to trade liberalization when imperfect labor markets are considered, (ii) to evaluate the impact of the recent reforms of the European agricultural policy on the world welfare. The results of two versions of a dynamic world computable general equilibrium (CGE) model, using the GTAP database version 6 are compared. In the first version, a standard world CGE approach is followed with perfect labor mobility across sectors. In the second version we assume that labor shifts freely within the aggregated sectors -agriculture, manufactures, services- but not across them .After a brief description of the two versions, changes in welfare, represented not only by the world GDP but also by the consumption level of two types of households (middle-low and middle-high) in 7 regions (Brazil, China, India, Least developed countries, European Union, United States, Rest of the World) after partial trade liberalization are presented. Theoretical and political consequences of the results are discussed.

description: The purpose of the study was to examine Addis Ababa Science and Technology University Engineering students’ views of wiki-based collaborative writing and the type of collaborative writing behavior exhibited while utilizing the wiki. For 10 weeks, the participants were joined in an essay-writing course that was linked with the wiki platform via http://befikadulemma.pbworks.com. The participants were selected using random sampling techniques. Questionnaires and students sample essays were sources of data. All students completed questionnaires; eight pairs were selected randomly to collect sample essays from the wiki interface. In the current study, a mixed research design was employed. Descriptive statistics were used to analyze the quantitative data. Students' perceptions of using a wiki and their technological self-efficacy were considered to analyze the quantitative data. Students viewed the use of wiki-based collaborative writing to develop their writing abilities favorably. Students' sample essays were also taken from wiki-discussion and history pages and analyzed qualitatively to identify the type of collaborative writing behavior they developed. The analysis was done thematically by considering the types of posts (content-related, language-related, phatic communication related, procedure-related, and product-related) they made and the types of revisions (surface and meaning-related changes) they carried out. The findings indicated that students showed both collaborative and non-collaborative behavior during the process of using wiki-based collaborative writing. Finally, EFL instructors have to train students on how to use technologies such as a wiki in their writing classes.

description: Widespread growth signatures in COVID-19 confirmed case counts are reported, with sharp transitions between three distinct dynamical regimes (exponential, superlinear and sublinear). Through analytical and numerical analysis, a novel framework is developed that exploits information in these signatures. An approach well known to physics is applied, where one looks for common dynamical features, independently from differences in other factors. These features and associated scaling laws are used as a powerful tool to pinpoint regions where analytical derivations are effective, get an insight into qualitative changes of the disease progression, and infer the key infection parameters. The developed framework for joint analytical and numerical analysis of empirically observed COVID-19 growth patterns can lead to a fundamental understanding of infection progression under strong control measures, applicable to outbursts of both COVID-19 and other infectious diseases.

description: Statewide average and critical rates of accidents were determined from 1970-1972 Kentucky accident records for each type of rural highway. Accident data, obtained from state police computer tapes, were summarized to give the number of accidents on each highway type as well as information on accident severity, road surface conditions, light conditions, road character, and type of traffic control. Four-lane undivided highways had the highest average accident rate; parkways (toll roads) had the lowest rate. The severity of accidents was related to types of accidents, highways, and traffic control and to safety belt usage. Accidents involving pedestrians were the most severe types; single-vehicle accidents ranked next highest in severity. Excluding accidents at railroad crossings, accidents which occurred on curves had the highest severity index. The use of safety belts was associated with reduced severity.

description: This paper analyses the efficiency with which water is used in small-scale irrigation schemes in North-West Province in South Africa and studies its determinants. In the study area, small-scale irrigation schemes play an important role in rural development, but the increasing pressure on water resources and the approaching introduction of water charges raise the concern for more efficient water use. With the Data Envelopment Analysis (DEA) techniques used to compute farm-level technical efficiency measures and sub-vector efficiencies for water use, it was shown that under Constant Returns to Scale (CRS) and Variable Returns to Scale (VRS) specification, substantial technical inefficiencies, of 49% and 16% respectively, exist among farmers. The sub-vector efficiencies for water proved to be even lower, indicating that if farmers became more efficient using the technology currently available, it would be possible to reallocate a fraction of the irrigation water to other water demands without threatening the role of small-scale irrigation. In a second step, Tobit regression techniques were used to examine the relationship between sub-vector efficiency for water and various farm/farmers characteristics. Farm size, landownership, fragmentation, the type of irrigation scheme, crop choice and the irrigation methods applied showed a significant impact on the sub-vector efficiency for water. Such information is valuable for extension services and policy makers since it can help to guide policies towards increased efficiency.
Evaluation and Modification of the Traffic Noise Prediction Procedure for Kentucky Highways

Subjects: subject: Transportation Engineering

description: Approximately 270 noise-level recordings were obtained at 39 highway sites and compared with the noise-level predictions obtained by the procedure outlined in NCHRP Report 117. The measured noise levels were computed in terms of the A-weighted L10 value (level exceeded 10 percent of time) and then compared to the predicted noise levels. A significant discrepancy was found between predicted and measured noise levels; generally, the predicted values exceeded the measured values. Average error per location was 4.8 dBA; the maximum error was 13 dBA. A nomograph was devised to correct the predicted value; this nomograph involves observer-to-roadway distances, truck volumes, and automobile speeds. By applying correction factors, the average error was reduced to 1.9 dBA, a 60-percent reduction in error. Based on these findings, the nomograph was approved by the Federal Highway Administration for use in predicting noise levels in Kentucky.
