description: QCD, the theory of the strong interactions, involves quarks interacting with non-Abelian gluon fields. This theory has many features that are difficult to impossible to see in conventional diagrammatic perturbation theory. This includes quark confinement, mass generation, and chiral symmetry breaking. This paper is a colloquium level overview of the framework for understanding how these effects come about.

description: In the network of seed mutations arising from a certain initial seed, an appropriate path emanating from the initial seed is intendedly chosen, noticing periodicity of the exchange matrices in the path each of which is assigned to the generalized Cartan matrix of type $A^{(1)}_N$. Then dynamical property of the seed mutations along the path, which is referred to as of type $A^{(1)}_N$, is intensively investigated. The coefficients assigned to the path form certain $N$ monomials that posses periodicity with period $N$ under the seed mutations and enable to obtain the general terms of the coefficients. The cluster variables assigned to the path of type $A^{(1)}_N$ also form certain $N$ Laurent polynomials possessing the same periodicity as the monomials generated by the coefficients. These Laurent polynomials lead to sufficiently number of conserved quantities of the dynamical system derived from the cluster mutations along the path. Furthermore, by virtue of the Laurent polynomials with periodicity, the dynamical system is non-autonomously linearized and its general solution is concretely constructed. Thus the seed mutations along the path of type $A^{(1)}_N$ exhibit discrete integrability.

description: Although it is often acknowledged that effective inclusion of small-scale primary producers in international chains is crucial for alleviating poverty in developing countries, few insights exist about how to build sustainable and all-inclusive food chains especially those based on scarce natural resources. In order to address challenges that marketing and development policy and institutions as well as small-scale primary producers in the agro-ecological sector face in promoting sustainable practices, this paper focuses on the use of contracts. The paper investigates whether small-scale primary producers would engage in contracts that oblige them to implement sustainable and quality-improving practices and if so under what conditions. Results show that primary producers (fishermen in this study) are open to sustainability-quality enhancing contracts provided that such contracts also enhance their welfare and economic benefits. Implications for building sustainable and all-inclusive international marketing channels are discussed.

description: The purpose of this study was to examine the global broadcast media’s coverage and framing of the Grand Ethiopian Renaissance Dam (GERD). For this purpose, four global media, namely British Broadcasting Corporation (BBC), Cable News Network (CNN), Aljazeera English (AJE), and China Global Television Network (CGTN) were selected purposively based on the North-South perspective. The study employed content analysis as its research design and archival data were collected from each of the sample media’s websites by using the fitting search engine of keywords. Accordingly, a total of 189 stories that fulfill the inclusion criteria were identified. To analyze the data, descriptive and thematic analyses were used. The result of the study revealed that CGTN and AJE gave more coverage to GERD than BBC and CNN. The result showed that, unlike the “North-South” dichotomy, both BBC and AJE represented GERD in a conflict frame. CNN framed the dam positively using the positive reference of assertions that favor the dam project sympathetically. The finding indicated that CGTN mainly framed GERD in a prognostic manner, which focused on the possible solutions to the current impasse on the dam between the concerned states. Government officials were identified as the most common sources of stories in all four target media. The study concluded that GERD was primarily framed as a source of conflict between Ethiopia and Egypt. Finally, the study suggested that more studies are needed on related projects across the Nile River region to better understand the role of the global media.

description: West African agriculture rice production represents only 50% of consumers' needs in the sub-region. The on-going negotiation on the Agreement on Agriculture and the establishment of a custom union within the ECOWAS offer an opportunity to reopen the discussion on the possible impact of appropriate trade regulation to stimulate the development of the domestic rice value chain. Based on the review of the outcome of recent studies and national statistics, comparing the rice sector history across different West African countries, the poster underlines that the competitiveness of domestic rice production does not depend only upon the cost efficiency of rice producer. It is adversely affected by the performance of the post-harvest operations which does not allow domestic product to match the quality of imported rice in terms of homogeneity and cleanliness. Consumers are ready to pay for a higher price for imported clean and well packed rice. Therefore the design of appropriate trade regulation cannot be limited to a discussion on the level of tariff to be applied by the ECOWAS custom union. Trade regulation could be used as buffer mechanisms to mitigate the negative impact of unpredictable world rice market trends on the willingness of private entrepreneur to invest in rice marketing and processing improvement.

description: We investigate a classical lattice system with $N$ particles. The potential energy $V$ of the scalar displacements is chosen as a $ϕ^4$ on-site potential plus interactions. Its stationary points are solutions of a coupled set of nonlinear equations. Starting with Aubry's anti-continuum limit it is easy to establish a one-to-one correspondence between the stationary points of $V$ and symbolic sequences $\bmσ = (σ_1,...,σ_N)$ with $σ_n=+,0,-$. We prove that this correspondence remains valid for interactions with a coupling constant $ε$ below a critical value $ε_c$ and that it allows the use of a ''thermodynamic'' formalism to calculate statistical properties of the so-called ``energy landscape'' of $V$. This offers an explanation why topological quantities of $V$ may become singular, like in phase transitions. Particularly, we find the saddle index distribution is maximum at a saddle index $n_s^{max}=1/3$ for all $ε< ε_c$. Furthermore there exists an interval ($v^*,v_{max}$) in which the saddle index $n_s$ as function of average energy $\bar{v}$ is analytical in $\bar{v}$ and it vanishes at $v^*$, above the ground state energy $v_{gs}$, whereas the average saddle index $\bar{n}_s$ as function of energy $v$ is highly nontrivial. It can exhibit a singularity at a critical energy $v_c$ and it vanishes at $v_{gs}$, only. Close to $v_{gs}, \bar{n}_s(v)$ exhibits power law behavior which even holds for noninteracting particles.

description: This three-parts glossary has been created in the frame of the wider project EcoNAOS that focused on the curation, valorization and sharing of a 50-years long database of abiotic, phyto- and zoo-plankton observations collected during oceanographic cruises in the Norther Adriatic Sea. From this project several outputs have been published: the database, a data paper, the code used to harmonize data, the workflow, the research ideas.
 This glossary comes from an effort made by the author to facilitate the introduction of new themes and terms in an heterogeneous research group compsed from Ecologists and IT experts. The first part regards the Openness: concepts and applications tied to Open Science principles. The second part concerns Open Geospatial and Geospatial Standards, useful in the FAIRification process of data. The third part deals, more broadly, with some Technical concepts that a researcher may encounter while opening scientific data. The result is a easy, ready to use and handy glossary that facilitate the dialogue between ecologists and IT scientists in the FAIRification process of scientific data.

description: In Ethiopia, problem behaviors in adolescents are commonly reported phenomena. However, studies examining how personal factor (self-regulation) influence the same are rarely found. Hence, the present study aimed to examine the effects of self-regulation on adolescents' disruptive behavior using family structure as a moderating variable. Correlational research design was employed to address the objectives of the study. Data were collected from a randomly selected 304 adolescent students (155 males, 149 females) using ‘the Problem Behavior Frequency Questionnaire’, and ‘Adolescents’ Self-Regulation Inventory’. Multiple regression analysis and two-way ANOVA were used to examine relationships and differences. Findings indicated that there is a statistically significant negative relationship between self-regulation and disruptive behavior in adolescents. Adolescents from non-intact family structures were found to engage in more disruptive behavior than adolescents from intact family structures. Male adolescents were found more active in disruptive behaviors than female adolescents. Self-regulation difference in adolescents as a function of their sex and family structure was reported. Sex and family structures moderate the relationship between self-regulation and disruptive behavior in adolescents. Because self-regulation is crucial to shield adolescents from engaging in disruptive behaviors, it is recommended that life skill training be provided for the adolescents in this study area in order to foster their self-control skills.

description: Single-step inkjet printing infiltration with doped ceria Ce0.9Ye0.1O1.95 (YDC) and cobalt oxide (CoxOy) precursor inks was performed in order to modify the properties of the doped ceria interlayer in commercial (50 × 50 × 0.5 mm3 size) anode-supported SOFCs. The penetration of the inks throughout the La0.8Sr0.2Co0.5Fe0.5O3-δ porous cathode to the Gd0.1Ce0.9O2 (GDC) interlayer was achieved by optimisation of the inks' rheology jetting parameters. The low-temperature calcination (750 °C) resulted in densification of the Gd-doped ceria porous interlayer as well as decoration of the cathode scaffold with nanoparticles (~20-50 nm in size). The I-V testing in pure hydrogen showed a maximum power density gain of ~20% at 700 °C and ~97% at 800 °C for the infiltrated cells. The latter effect was largely assigned to the improvement in the interfacial Ohmic resistance due to the densification of the interlayer. The EIS study of the polarisation losses of the reference and infiltrated cells revealed a reduction in the activation polarisations losses at 700 °C due to the nano-decoration of the La0.8Sr0.2Co0.5Fe0.5O3-δ scaffold surface. Such was not the case at 800 °C, where the drop in Ohmic losses was dominant. This work demonstrated that single-step inkjet printing infiltration, a non-disruptive, low-cost technique, can produce significant and scalable performance enhancements in commercial anode-supported SOFCs.

description: This paper presents the case for research on institutional environments for organically certified agriculture in developing countries. Observing that some analyses hold Southern organic agriculture as pro-poor and perhaps also more energy efficient than fossil fuel dependent industrialized agriculture, the paper explores differences and similarities in the policy rationale of promoting certified organics in North and South. Based on analysis of institutional environments for COA in Brazil and China, the paper proceed to identify some challenges, opportunities and policy options for strengthening not only certified organic agriculture per se, but an environmentally and socially sustainable food system, providing smallholder livelihoods and rural development.
Prospects of Ethiopia’s Energy Led Integration with the Horn of Africa: Opportunities and Challenges
Creators: name: Tadesse, Abera
Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2022

description: Energy led cooperation has been seen in different parts of the world as a strategy of attaining energy security and regional economic integration. Since recently, it has been also seen in different regions of Africa including the Horn of Africa (hereafter HoA). Energy cooperation in the HoA has been regarded as a good step to promote relations between countries in the region in various forms. This study has two separate but interrelated objectives. Firstly, it assesses Ethiopia’s energy led integration efforts with the HoA and major opportunities therein. Secondly, the paper discusses the key challenges of Ethiopia’s energy led integration efforts with the region. The study uses both primary and secondary data. To substantiate the analysis, theoretical assumptions of Realism, Functionalism, and Neo-Functionalism are utilized. The findings of this study indicates that Ethiopia’s energy led cooperation schemes with the HoA are increasing from time to time and have a good prospect for further regional energy integration. Thus, Ethiopia’s energy led cooperation with the region is incrementally and functionally becoming more in line with theories of functionalism and neo-functionalism. However, it also asserts that political instability of the region, lack of trust among countries, and hydro politics of the Eastern Nile basin inform that assumptions of realism are also important to explain energy based integration in the HoA region. Nonetheless, if due attention is given by political elites, energy led integration schemes in the HoA are with great potentials in addressing the unresolved political, economic and social crises of the region.

description: The defining feature of active particles is that they constantly propel themselves by locally converting chemical energy into directed motion. This active self-propulsion prevents them from equilibrating with their thermal environment (e.g., an aqueous solution), thus keeping them permanently out of equilibrium. Nevertheless, the spatial dynamics of active particles might share certain equilibrium features, in particular in the steady state. We here focus on the time-reversal symmetry of individual spatial trajectories as a distinct equilibrium characteristic. We investigate to what extent the steady-state trajectories of a trapped active particle obey or break this time-reversal symmetry. Within the framework of active Ornstein-Uhlenbeck particles we find that the steady-state trajectories in a harmonic potential fulfill path-wise time-reversal symmetry exactly, while this symmetry is typically broken in anharmonic potentials.

description: Results of a study of physical parameters of stellar population in star formation regions in galaxies with signs of peculiarity NGC 3963 and NGC 7292 are presented. The study was carried out based on the analysis of photometric (UBVRI bands), H-alpha and spectroscopic data obtained by the authors, using evolutionary models of stellar population. Among 157 star formation regions identified in galaxies, the young stellar population mass estimates were obtained for 16 of them and the age estimates were obtained for 15. The age of star formation regions clearly correlates with the presence of emission in the H-alpha line: HII regions in the galaxies are younger than 6-8 Myr, and the regions without gas emission are older. The studied objects are included in the version 3 of our catalogue of photometric, physical and chemical parameters of star formation regions, which includes 1667 objects in 21 galaxies. Key aspects of the technique used to estimate the physical parameters and different relations between observational and physical parameters of the young stellar population in star formation regions are discussed.

description: The purpose of this study was to examine the effect of servant leadership on organizational justice in the public universities of the Amhara region. A descriptive survey and correlational design were used. The size of the population was 2170. Of these, 705 instructors were selected using proportional stratified random sampling technique. A standard questionnaire was used to collect the data. One sample t-test, structural equation modelling, multiple regression and one-way ANOVA were employed to analyse the data. The result of one sample t-test indicated that department heads manifested servant leadership behavior in relation to emotional healing, creating value for the community, conceptual skills, helping subordinates grow and succeed moderately while empowering, putting subordinates first and behaving ethically were observed to a limited extent. Similarly, distributive justice was found to some extent but procedural and interactional justice were observed to a little extent. There was a statistically significant relationship between servant leadership and organizational justice. The result of multiple regression indicated that 36.1% of the variance in organizational justice was significantly predicted by emotional healing, creating value for the community, conceptual skill, helping subordinates grow and succeed, and behaving ethically. Significant differences were found among instructors in their perception of servant leadership and organizational justice based on the generations of universities. Thus, it is concluded that servant leadership had significant effect on organizational justice. Therefore, it is suggested to improve the current status of servant leadership and organizational justice in the universities.

description: Aspect-based Sentiment analysis (ABSA) accomplishes a fine-grained analysis that defines the aspects of a given document or sentence and the sentiments conveyed regarding each aspect. This level of analysis is the most detailed version that is capable of exploring the nuanced viewpoints of the reviews. The bulk of study in ABSA focuses on English with very little work available in Arabic. Most previous work in Arabic has been based on regular methods of machine learning that mainly depends on a group of rare resources and tools for analyzing and processing Arabic content such as lexicons, but the lack of those resources presents another challenge. In order to address these challenges, Deep Learning (DL)-based methods are proposed using two models based on Gated Recurrent Units (GRU) neural networks for ABSA. The first is a DL model that takes advantage of word and character representations by combining bidirectional GRU, Convolutional Neural Network (CNN), and Conditional Random Field (CRF) making up the (BGRU-CNN-CRF) model to extract the main opinionated aspects (OTE). The second is an interactive attention network based on bidirectional GRU (IAN-BGRU) to identify sentiment polarity toward extracted aspects. We evaluated our models using the benchmarked Arabic hotel reviews dataset. The results indicate that the proposed methods are better than baseline research on both tasks having 39.7% enhancement in F1-score for opinion target extraction (T2) and 7.58% in accuracy for aspect-based sentiment polarity classification (T3). Achieving F1 score of 70.67% for T2, and accuracy of 83.98% for T3.
Oxidized low density lipoprotein causes impaired efflux of cholesterol from macrophages : implications for atherogenesis
Creators: name: Dhaliwal, Baljinder Singh
Publisher: name: University of British Columbia
Year: 2009

description: Oxidation of low density lipoproteins (LDL) has been implicated as a causal factor in the pathogenesis of atherosclerosis. Oxidized LDL has been found to exhibit numerous potentially atherogenic properties, including receptor-mediated uptake by macrophages. The present study confirms that oxidized LDL is resistant to intracellular degradation and accumulates in a lysosomal compartment in macrophages. Continued accumulation of lipid by macrophages in the arterial intima results in transformation of these cells into lipid-laden "foam cells", which are one of the earliest signs of atherosclerosis. It is believed that high density lipoprotein (HDL) protects against atherosclerosis by removing excess cholesterol from cells of the artery wall, thereby retarding lipid accumulation by macrophages. We investigated the relative rates of HDL-mediated cholesterol efflux in murine resident peritoneal macrophages that had been loaded with acetylated LDL or oxidized LDL. It was found that acetylated LDL-loaded cells released approximately one-third of their total cholesterol to HDL-containing medium, whereas oxidized LDL-loaded cells released only one-tenth of their total cholesterol. To determine whether the impairment of cholesterol efflux was due to modification of the apolipoprotein B or the lipid component of LDL, cells were loaded with either acetylated LDL that had been oxidized for 5 hours or native LDL that had been modified with oxidized arachidonic acid. It was found that both the oxidized lipid component and the modified apolipoprotein B contributed to impaired efflux of cholesterol. To ascertain the proportion of cholesterol efflux mediated by the apolipoprotein component compared to the lipid component of HDL, we measured the rate of efflux when the cells were treated with trypsinized HDL. Very little efflux occurred when the macrophages were treated with trypsinized HDL, underscoring the importance of intact apolipoprotein in HDL-mediated cholesterol efflux. We also investigated the subcellular distribution of cholesterol in oxidized LDL-loaded cells and acetylated LDL-loaded cells. Our findings suggest that in contrast to acetylated LDL-derived cholesterol, oxidized LDL-derived cholesterol accumulates within lysosomes. The observed impairment of cholesterol efflux in oxidized LDL-loaded macrophages may influence the generation of foam cells in vivo, and should, therefore, be considered one of the more important atherogenic effects of oxidized LDL.

L’intento è quello di dimostrare che il vuoto in un pro- getto non si percepisce più come assenza ma come elemento percettibile e distintivo. “Il vuoto, anche se invisibile è infatti paradossalmen- te ciò che permette alle cose di farsi visibili, ciò che garantisce la loro visibilità. Il vuoto non è altro che la distanza tra gli elementi del reale, l’ambito in cui si de- finiscono le loro relazioni. Senza il vuoto gli oggetti non esistono, o meglio, non esistono oggetti riconoscibili. [...] E’ questo il compito principale che compete al vuo- to: mantenere la separazione tra gli elementi mettendo in evidenza il campo delle relazioni”

description: Pedestrian accident data in Kentucky were analyzed for 1972 and 1973 on a rural, urban, and statewide basis. Results showed that about 1500 pedestrian accidents occur in Kentucky each year. About 30 percent of the pedestrian accidents in rural areas and four percent in urban areas are fatal. Although about 78 percent of Kentucky's pedestrian accidents occur in urban areas, over 62 percent of the pedestrian fatalities occur in rural areas. Specific characteristics of pedestrian accidents were identified and related to human, environmental, and time factors. Highway and street improvements and safety measures generally considered to be effective in minimizing pedestrian accidents are summarized.

Food Security and Poverty

description: There is increasing insight into how household poverty in rural and peri-urban areas is affected by developments in the markets for fruit, vegetables and flowers. This study extends the knowledge, and feeds into the debate on agricultural growth policies. Based on a positive outlook on the growth of horticultural production and distribution and marketing in the low income countries of Uganda and Vietnam, this paper asks whether poor and vulnerable groups in society share in the benefits of the foreseen economic expansion. Primary survey data is collected on the differentiated position of low-income households in different supply structures (with varying levels of vertical coordination) and markets (national, regional and international markets). The data support the following hypotheses: (i) For many resource-poor agents, horticulture-related activities make substantial contributions to their livelihood security certainly in the short term. (ii) Farming, trading services, small-scale retail, and farm labour are activities to which members of resource-poor and economically vulnerable households have the best access given their endowments. (iii) A move from food production for home consumption towards cash crops or off-farm labour is supported when there are sufficient options to reduce livelihood risk in the household. (iv) Both value creation and the generation of opportunities for (self-) employment in domestic marketing channels are substantial, and possibly outweigh the economic impact of overseas export marketing. Policy support is best tailored to specific conditions and specific actors to achieve a maximum impact on poverty alleviation. For that purpose, a three-tiered grouping of marketing channels for livelihood development is proposed.

In addition, let $Δ_G$ be the intersection graph of $G$, whose vertices are the proper nontrivial subgroups of $G$, with distinct subgroups joined by an edge if and only if they intersect nontrivially. We prove that the diameter of $Δ_G$ has a tight upper bound of 5, thereby resolving a question posed by Shen (2010). Furthermore, a diameter of 5 is achieved only by the baby monster group and certain unitary groups of odd prime dimension.

description: We present detailed evolutionary calculations focused on the evolution of intermediate mass stars with 3 Msun < M < 9 Msun of metallicity typical of the Large Magellanic Cloud (LMC), i.e. Z=0.008. We compare carefully the models calculated by adopting a diffusive scheme for chemical mixing, in which nuclear burning and mixing are self-consistently coupled, while the eddy velocities beyond the formal convective core boundary are treated to decay exponentially, and those calculated with the traditional instantaneous mixing approximation. We find that: i) the physical and chemical behaviour of the models during the H-burning phase is independent of the scheme used for the treatment of mixing inside the CNO burning core; ii) the duration of the He-burning phase relative to the MS phase is systematically longer in the diffusive models, due to a slower redistribution of helium to the core from the outer layers; iii) the fraction of time spent in the blue part of the clump, compared to the stay in the red, is larger in the diffusive models. The differences described in points ii) and iii) tend to vanish for M > Msun. In terms of the theoretical interpretation of an open cluster stellar population, the differences introduced by the use of a self-consistent scheme for mixing in the core with adjacent exponential decay are relevant for ages in the range 80 Myr < t < 200 Myr. These results are robust, since they are insensitive to the choice of the free-parameters regulating the extension of the extra-mixing region.

description: One of the principal objectives of the survey of a group of wheat farms in the central-west of New South Wales, conducted by the Division of Marketing & Agricultural Economics in February and March, 1951, was to ascertain the cost of operating machinery in use in the wheat industry. An account of the survey, which was carried out on 94 farms in the Shires of Goobang and Jemalong and in the Municipalities of Parkes and Forbes) was published in the previous issue of this journal'. In this article consideration will be given to conclusions drawn from this survey as to the cost of operating tractors and selected implements. The implements selected for consideration-the twin-disc plough ("sundercut"), scarifier, combine and header-include all but two of those implements which were in general use on wheat farms in the district in which the survey was carried out. Binders and tyne harrows (both the stump-jump and diamond type) were also widely used on most farms, but only for relatively short periods of the year. The data supplied by fanners participating in the survey was inadequate to allow of any analysis being undertaken of the costs of operating implements other than the four mentioned.

description: The purpose of this study was to scrutinize the effects of listening strategies on the listening performance and motivation of EFL students. The study used a quasi-experimental design that rearranged students into experimental and control groups, which required pre- and post-tests. The subjects of the study were 2021 enrolled first-year Natural science students at Mettu University. Two intact sections (50 students in each section) participated. Listening achievement tests, motivational inventory questionnaires and interviews were used as data collection instruments. After the pre-test was undertaken for both groups, the strategy intervention was given for the experimental group. During strategy training, the experimental group was taught listening strategy training with different strategies of instructions (cognitive, metacognitive, and social affective), while the control group was taught through conventional instruction for ten weeks, and both groups received a post-test. Both inferential and descriptive data analyses were used. Finally, the results of the study showed that the students who undertook strategy training outperformed the control group, as the p-value was less than 0.05; which is 0.000 or (p<0.05). Furthermore, the results of the independent sample t-test, motivation inventory questionnaire and interview confirmed that teaching listening strategies had a positive effect on students' listening achievement and those students underwent the strategy instruction were motivated than the other one . Finally, based on the results of the study, it is possible to suggest that classroom teachers need to give due emphasis on the fundamental importance of listening and teaching listening strategy in the EFL classroom.

description: We study static spherically symmetric solutions to the vacuum field equations of quadratic gravity in the presence of a cosmological constant $Λ$. Motivated by the trace no-hair theorem, we assume the Ricci scalar to be constant throughout a spacetime. Furthermore, we employ the conformal-to-Kundt metric ansatz that is valid for all static spherically symmetric spacetimes and leads to a considerable simplification of the field equations. We arrive at a set of two ordinary differential equations and study its solutions using the Frobenius-like approach of (infinite) power series expansions. While the indicial equations considerably restrict the set of possible leading powers, careful analysis of higher-order terms is necessary to establish the existence of the corresponding classes of solutions. We thus obtain various non-Einstein generalizations of the Schwarzschild, (anti-)de Sitter [or (A)dS for short], Nariai, and Plebański-Hacyan spacetimes. Interestingly, some classes of solutions allow for an arbitrary value of $Λ$, while other classes admit only discrete values of $Λ$. For most of these classes, we give recurrent formulas for all series coefficients. We determine which classes contain the Schwarzschild-(A)dS black hole as a special case and briefly discuss the physical interpretation of the spacetimes. In the discussion of physical properties, we naturally focus on the generalization of the Schwarzschild-(A)dS black hole, namely the Schwarzschild-Bach-(A)dS black hole, which possesses one additional Bach parameter. We also study its basic thermodynamical properties and observable effects on test particles caused by the presence of the Bach tensor. This work is a considerable extension of our letter [Phys. Rev. Lett., 121, 231104, 2018].

Non-perturbative k-body to two-body commuting conversion Hamiltonians and embedding problem instances into Ising spins

description: An algebraic method has been developed which allows one to engineer several energy levels including the low-energy subspace of interacting spin systems. By introducing ancillary qubits, this approach allows k-body interactions to be captured exactly using 2-body Hamiltonians. Our method works when all terms in the Hamiltonian share the same basis and has no dependence on perturbation theory or the associated large spectral gap. Our methods allow problem instance solutions to be embedded into the ground energy state of Ising spin systems. Adiabatic evolution might then be used to place a computational system into it's ground state.

description: Motivated by the back-reaction debate, and~some unexplained characteristics of the CMB, we investigate the possibility of some anisotropy in the universe observed around us. To this aim, we build up a novel prediction for the Hubble law for the late universe from a Bianchi type I model, {taken as proof of concept,}
 transcribing the departure of such model from a $Λ$CDM model. We~dicussed the redshift measurement in this universe, and~finally formalized the Hubble diagram.

description: The purpose of the study was to investigate parental goals, beliefs, and values in child rearing practices among West Wollega Oromo Community. Survey research design was used to conduct the study. From the total of 10,270 target populations of West Wollega Oromo parents, 212 respondents were selected through disproportionate stratified random sampling technique. Quantitative data generated through the close-ended questionnaire were analyzed using descriptive statistics and independent sample t-test, while qualitative data obtained via open ended questionnaire were analyzed in words. The results revealed that West Wollega Oromo parents’ child rearing highly encourages collectivism as their parental goal, while there was minimal encouragement level for individualism as parental goal; particularly in urban areas. Regarding parental beliefs, the majority of parents believe that establishing restrictive relationship with their children is an ideal child rearing, while a few parents were in favor of interactive relationship with their children. Moreover, the majority of parents believe that physical and verbal punishments are more important than verbal advice at times mistake is committed by children. Yet, the majority of the respondents believe that children’s idea expression should be controlled by the adults, while a few believe that children should express their ideas with freedom. It is recommended that professionals like developmental psychologists should play their role in training parents to help them improve their parenting practices and thereby foster healthy development physically, socially and psychologically through having interactive relationship than restrictive relationship with their children.

description: This study examined the teacher’s practices as a transformative intellectual in teaching communicative English skills course at Ambo University. Using a quasi-experimental research design, all 253 students who were admitted to Natural Science (135) and Social Science (118) bands were considered using comprehensive sampling techniques. A pre-intervention test was administered to all the students to determine their baseline language skills. Next, the students were proportionally stratified into two groups based on their pretest results, field of study and sex category, who were later assigned to control and experimental groups using lottery system. Consequently, transformative intellectual strategy was carried out for thirteen weeks for the experimental group of students while the control group of students was taught using conventional methods in their regular classrooms. In the end, post-intervention test was carried out to determine the effectiveness of transformative intellectual strategy. The data obtained through test, classroom observation, and attitudinal survey questionnaire were analyzed quantitatively using percentage, mean, standard deviation, t-test and Mann-Whitney U test to determine the effectiveness of the intervention, and qualitatively using thematic analysis. The findings (t = 7.55 and Z = 0.95) showed that teacher’s practices of transformative intellectual significantly improved students’ communicative English skills, with 17.14%. The students in the experimental group were motivated towards communicative English skills course. They were challenged in using transformative intellectuals in the course. The solution of the problem lies on the improvement of the challenges.
