description: It is well known that usual quantum teleportation protocols cannot transport energy. Recently, new protocols called quantum energy teleportation (QET) have been proposed, which transport energy by local operations and classical communication with the ground states of many-body quantum systems. In this paper, we compare two different QET protocols for transporting energy with electromagnetic field. In the first protocol, a 1/2 spin (a qubit) is coupled with the quantum fluctuation in the vacuum state and measured in order to obtain one-bit information about the fluctuation for the teleportation. In the second protocol, a harmonic oscillator is coupled with the fluctuation and measured in order to obtain continuous-variable information about the fluctuation. In the spin protocol, the amount of teleported energy is suppressed by an exponential damping factor when the amount of input energy increases. This suppression factor becomes power damping in the case of the harmonic oscillator protocol. Therefore, it is concluded that obtaining more information about the quantum fluctuation leads to teleporting more energy. This result suggests a profound relationship between energy and quantum information.

An investigation of pricing and profitability in the short-stay accommodation industry in Tasmania
Creators: name: Marsden, A
Publisher: name: University Of Tasmania
Year: 2023

description: Accommodation providers worldwide are readily observed to adopt a variety of pricing strategies. However there has not previously been an academic study of pricing in the Tasmanian industry. This thesis aims to provide a systematic study of the decisions made by short-stay accommodation providers in Tasmania, and the implications of these decisions on their profitability. Information on the Tasmanian short-stay accommodation industry was obtained from a survey of firms in this industry using a questionnaire designed by the researcher. The use of this method generates a novel data set, one that provides a broad overview of the practices in the industry. Data that would otherwise not be observable were obtained. Notably, innovations in the design of the questionnaire allowed the investigator to directly identify the elasticity of demand in sub-markets. Cost variables are likewise identified. Data generated by the survey allow the following three analyses to be conducted: 1. The survey data reveal that firms in the short-stay accommodation industry use direct price discrimination by assessing the price sensitivity of groups of customers. These groups are identifiable by the firm and are based on the booking process chosen by the customer, whether they are a corporate or leisure customer and whether they are a repeat or first-visit customer. This result provides evidence that firms use third degree price discrimination in practice. 2. An analysis of the determinants of the firm's elasticity of demand is conducted. It is found that increases in the star rating (quality) of the firm reduces the elasticity of demand and an increase in the competitiveness of the environment in which the firm operates increases the elasticity of demand. 3. An analysis of the determinants of firm profitability is conducted. The analysis reveals that the use of the website Wotif.com by the firms is an important determinant of profitability in this industry. However the star rating of the firm, whether or not it is the winter season, and the proportion of customers who make their bookings at the door are also found to be key determinants of profitability. The conclusions from this study are of practical as well as academic interest. As with many regional areas, the short-stay accommodation industry in Tasmania is an important component of the local economy. Firms' pricing decisions will be an important determinant of their profitability. The success of these firms is of interest to their local communities and policy makers. The findings of this thesis are thus useful in informing policy discussion and analysis.

Using Proxy Pattern-Mixture Models to Explain Bias in Estimates of COVID-19 Vaccine Uptake from Two Large Surveys
Creators: name: Andridge, Rebecca R
Publisher: name: arXiv
Year: 2023
Subjects: subject: Applications (stat.AP)
subject: FOS: Computer and information sciences

description: Recently, attention was drawn to the failure of two very large internet-based probability surveys to correctly estimate COVID-19 vaccine uptake in the United States in early 2021. Both the Delphi-Facebook CTIS and Census Household Pulse Survey (HPS) overestimated uptake substantially, by 17 and 14 percentage points in May 2021, respectively. These surveys had large numbers of respondents but very low response rates (<10%), thus, non-ignorable nonresponse could have had substantial impact. Specifically, it is plausible that "anti-vaccine" individuals were less likely to participate given the topic (impact of the pandemic on daily life). In this paper we use proxy pattern-mixture models (PPMMs) to estimate the proportion of adults (18+) who received at least one dose of a COVID-19 vaccine, using data from the CTIS and HPS, under a non-ignorable nonresponse assumption. Data from the American Community Survey provide the necessary population data for the PPMMs. We compare these estimates to the true benchmark uptake numbers and show that the PPMM could have detected the direction of the bias and provide meaningful bias bounds. We also use the PPMM to estimate vaccine hesitancy, a measure for which we do not have a benchmark truth, and compare to the direct survey estimates.
Executive function : a comparison between normal ageing adults and older adults suffering traumatic brain injury
Creators: name: Dawson, TA
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis contrasted the performance of normal ageing adults with older TBI patients on one of the most elusive neuropsychological constructs, executive function. Executive function purportedly controls and integrates cognitive activity, reflecting conscious, strategic goal-directed operations (Stuss & Levine, 2002). However, debate rages as to whether executive function is actually a distinct construct, or merely represents g (Salthouse, 2005; Wood & Liossi, 2007). With respect to normally ageing, it is promulgated that executive functions are among the first to be impacted given that the 'seat' of executive function, the frontal lobes, decline at a faster rate than other brain regions (West, 1996). The pathophysiology of traumatic brain injury (TBI) also renders the frontal lobes and thus executive function vulnerable (McDonald, Flashman & Saykin, 2002), and older adults have the second higher incidence of TBI. As such, both groups represent logical choices to study and a research paucity exists (Garden, Phillips & MacPherson, 2001; Rappoport et al. 2006). This thesis aims to reduce this paucity by further elucidating the executive function of both these populations. A secondary aim is to further examine the utility of the Alternate Uses (AU) Test (Guilford, Christensen, Merrifield & Wilson, 1978) as a measure of executive function. Study 1 examines the performance of a normal ageing cohort (n= 100, age range 50-79 years) on measures of executive function, memory and processing speed. An age related decline was hypothesised to differentially impact executive measures. The results however ran contrary to predictions; while there was some impact of age on executive function, memory and information processing speed also suffered. Study 2 recruited a group of older TBI sufferers (n = 20, age range 50-79 years) at 6-12 months post injury. Patients were tested against age and education matched controls from Study 1. Executive function was expected to be preferentially impacted by TBI and this hypothesis was supported. The Alternate Uses paradigm showed sensitivity to both normal ageing and TBI. Ultimately, the author postulates that executive function may not be a particularly useful concept among normal populations. The equivocal state of the literature, historical problems with defining and measuring executive function and doubt as to whether executive function merely represents g, coupled with the lack of a differential age decrement in the current study all contribute to this viewpoint. Executive dysfunction on the other hand has long held relevance in clinical settings.

description: Graphene and its derivatives have many superior electrical, thermal, mechanical, chemical, and structural properties, and promise for many applications. One of the issues for scalable applications is the lack of a simple, reliable method that allows the deposit of a well-ordered monolayer using low-cost graphene flakes onto target substrates with different surface properties. Another issue is the adhesion of the deposited graphene thin film, which has not been well investigated yet. Following our former finding of a double self-assembly (DSA) process for efficient deposition of a monolayer of graphene flakes (MGFs), in this work we demonstrate that the DSA process can be applied even on very challenging samples including highly hydrophobic polytetrafluoroethylene (PTFE), flexible textiles, complex 3D objects, and thin glass fibers. Additionally, we tested adhesion of the graphene flakes on the flat glass substrate by scotch tape peel test of the MGFs. The results show that the graphene flakes adhere quite well on the flat glass substrate and most of the graphene flakes stay on the glass. These findings may trigger many large-scale applications of low-cost graphene feedstocks and other 2D materials.
Investigation of fluid surface waves with a new microwave resonance technique
Creators: name: Pike, Robert L.
Publisher: name: University of British Columbia
Year: 2011

description: A new microwave technique has been developed for the experimental study of small amplitude surface waves on an electrically conducting fluid. The fluid forms one of the walls of a resonating, microwave cavity. Surface waves with amplitudes as small as 10⁻³ cm. can be measured by observing the resulting change in the resonant frequency of the cavity. This technique has been successfully used to measure the viscous and magnetic damping coefficient of a small amplitude, standing, surface wave in liquid mercury. The magnetic damping, coefficient (for a vertical, magnetic field) was found to be in good agreement with a calculation that was made, for low magnetic Reynolds numbers. When the viscous damping coefficient was compared with the standard theory, which allows horizontal motion of the. surface, a disagreement of up to a factor of four was found. It, however, showed excellent agreement with a modified theory which assumes that there, is no horizontal motion of the surface.

description: We study the properties of the holographic CFT dual to Gauss-Bonnet gravity in general $D \ge 5$ dimensions. We establish the AdS/CFT dictionary and in particular relate the couplings of the gravitational theory to the universal couplings arising in correlators of the stress tensor of the dual CFT. This allows us to examine constraints on the gravitational couplings by demanding consistency of the CFT. In particular, one can demand positive energy fluxes in scattering processes or the causal propagation of fluctuations. We also examine the holographic hydrodynamics, commenting on the shear viscosity as well as the relaxation time. The latter allows us to consider causality constraints arising from the second-order truncated theory of hydrodynamics.

description: The company Vertebradas Artes Escénicas arises from the permanent Inclusive Theatre Workshop that the creator, director, and educator Laura Suárez (https://lauraenorbita.com/) created and guided in 2015 with the interest of deepening the method of the theatre of experience, experimenting in acting techniques and collective creation. The scenic language of our shows is the reflection of this research and the fruit of almost 20 years of uninterrupted work with people with intellectual and psychic functional diversity. A transversal language where each of the performers can express themselves from their abilities, a quality inherent to the term “inclusion”, and which sensitively enriches the group's expression.
A cornerstone of the company’s values, equality and inclusion accompany all the productions of Vertebradas Artes Escénicas in different professional areas. The creative and scenic quality of these productions is a reflection of the diversity of the group and the benefit of difference.
Vertebradas premiered its first show, Diversas Mujeres, in 2017 at the Universidad Autónoma de Madrid. Since then, it has participated in the III and VI Festival Visibles and has performed at Teatro Mira, Sala Tarambana, Nave 73, Congreso Internacional Aletheia - Universidad Complutense of Madrid.
Molinos ¡a mí! (2020), is the company’s second show and was premiered at the Teatro Cervantes in Alcalá de Henares as part of the 15th European Consortium for Arts Therapies in Education ECARTE. It participated in the IV Festival Visibles and in the 1st Conference on Culture and Disability, Collado Villalba. During 2021 it formed part of the Teatro del Barrio programme.
Baila el bosque is the last show premiered by the company in 2023, as part of the VIII Festival Visibles at the Teatro Pradillo in Madrid.

description: Public relations is not a new term. It is, however, becoming more popular and necessary in the modern concept of school activities. Public relations pertains to the whole school system, but this study will deal only with public relations as it affects the industrial arts program of the school. Because industrial arts is a relatively new addition to the school curriculum, and because the par-pupil cost is generally higher than that for other subjects, the value of the program must be defended and publicized. One of the best ways to prevent the industrial arts program from being classified as a “fad” or “frill” in the education system is to make effective use of as many public relations possibilities as practicable.

The Palawa (Tasmanian aboriginal) languages : a preliminary discussion
Creators: name: Taylor, JA
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis provides a preliminary discussion of the Palawa ('Tasmanian Aboriginal') languages. Tasmania as an island has been physically separated from the Australian mainland for over ten millennia, and as one might expect one consequence has been that there have been a number of divergences in the development of its languages from those of the mainland in terms of the pronunciation and range of its segments, its phonology, the semantic content of its lexemes, its word and sentence construction, and its syntax. To adequately cover all these topics, and as well the genetic connections between Palawa and the mainland languages would be a vast enterprise running into many hundreds of pages. In consequence the thesis has been limited to a number of matters which are basic to an adequate discussion of the topics referred to. The thesis thus provides a description of Tasmania as a geophysical land mass which differs in important respects from most of mainland Australia, and of the important changes which have taken place since its human colonisation in terms of its climate, fauna, and flora. An outline of the languages and dialects spoken at the beginning of the nineteenth century follows, together with a description of Palawa socio-economic organization. As then discussed, the rapid collapse of Palawa culture after Tasmania's invasion by the British, led to the loss and very imperfect preservation of the Palawa languages. Chapter 6 details the sources of the extant materials with respect to the languages, and provides an overview of studies undertaken to date. Chapter 7 then proceeds to an in depth study of the Palawa lexicons with a view to identifying and determining the segments regularly articulated by Palawa speakers, and the contexts in which those segments were contrastive. This study will incorporate all extant information with respect to the various spelling conventions used in European transcriptions of Palawa words. It will also compare the transcriptions with a view to resolving a number of both latent and patent ambiguities. The principles of historical linguistics will be used to elucidate many such matters. The thesis will not embark upon a description of Palawa phonology, morphology, the semantic development and content of Palawa lexemes, nor Palawa syntax. Accordingly a discussion of Palawa place names, clan names, and personal names will also not form part of the thesis.

description: The need of smooth surface finish produced during machining process plays a greater role to reduce wear of the part and corrosion protection. However, the cost of making good surface finish depends on selection of optimized parameters and use of precision machines. Dry turning operation is very important for saving cost of cutting fluid, contribute to clean environment and good for safety of machinist. Pure copper produces a long tubular or tangled chips which makes machining very difficult because chips are rolled on cutting tool causing tool wear. Machining of high ductility work material like copper can create high frictional forces between chip and cutting tool. This creates high tool wear due to poor chip formation. In this work, cutting parameters like cutting speed, depth of cut and feed are optimized for dry turning process using Taguchi Method. The optimum turning parameters in this study was obtained at higher cutting speed, lower feed and higher depth of cut. The minimum surface roughness at optimum turning parameters was obtained as 1.63 µm. Result of variance indicates the contribution of cutting speed, feed and depth of cut were 88.74%, 1.13% and 6.46% respectively. Among which cutting speed was the most significant factor for improving surface roughness.

description: Mango (Mangifera indica L.) has been cultivated in Ethiopia at small scale level so far, but very few large scale farms have started to join the sector in recent days. Mango production in Ethiopia is currently constrained by white mango scale (Aulacaspis tubercularis). This study was performed to evaluate the efficacy of three formulations, i.e. Folimat, Closer 240 and D-C-Tron Plus, against white mango scale (WMS) on mango from mid-May 2016 to end of July 2016 in west Oromia. The experiment was laid in a Randomised Complete Block Design (RCBD) with three replications. Volume of water enough for complete coverage of a mango tree was calibrated and repetitive treatment and response recording were conducted. The insecticides were applied by manual Knapsack sprayer, every 14 days for a total of three times. A total of ten leaves were picked randomly from the treatments and the untreated control one day prior to each treatment and on the 5th and 10th days after each treatment. Live crawler; male and female WMSs were counted by the use of stereo microscope and recorded as number of live WMS. Folimat showed maximum pest population reduction followed with Closer 240. However, some non-target insects were found dead on trees treated with Folimat, an observation to be confirmed by further investigation. Incorporating the less toxic insecticide, Closer 240 SC which showed a certain degree of the pest population reduction, in to Integrated Pest Management to control the white mango scale infestation on big trees of mango landrace is recommended.

description: TThe major purpose of this study was to investigate the status of parental involvement in school management. To this end, a descriptive survey research design has been used to collect relevant data from 35 representatives of parents and 40 directors/vice directors in five government and seven private secondary schools in Adama City Administration using questionnaire, focus group discussion, and key informant interview. The quantitative data were analyzed using descriptive and inferential statistics while the qualitative data were analyzed thematically. Results of the study reveal that both parents and directors seem to have positive attitude towards parental involvement in school management, yet the actual practice on the ground is not satisfactory. Parents’ involvement is limited to raising and supervising the utilization of school fund and fulfilling school infrastructure. They have minimal involvement in planning school activities, supervising teachers, providing of pedagogical support, and recruiting students due to barriers such as time constraint, lack of initiative, lack of awareness on how to contribute, and absence of incentives for parents. Although there are some differences in their mean values, statistically significant differences between private school and government school parents with regards to their involvement in school management were observed only on two domains: raising fund and managing students’ discipline. Hence, working closely with community based association, raising parents’ awareness through trainings, and providing incentives have been recommended.

description: Proceeding from nonlinear realizations of (super)conformal symmetries, we explicitly demonstrate that adding the harmonic oscillator potential to the action of conformal mechanics does not break these symmetries but modifies the transformation properties of the (super)fields. We also analyze the possibility to introduce potentials in N=4 supersymmetric mechanics by coupling it with auxiliary fermionic superfields. The new coupling we considered does not introduce new fermionic degrees of freedom - all our additional fermions are purely auxiliary ones. The new bosonic components have a first order kinetic term and therefore they serve as spin degrees of freedom. The resulting system contains, besides the potential term in the bosonic sector, a non-trivial spin-like interaction in the fermionic sector. The superconformal mechanics we constructed in this paper is invariant under the full $D(2,1;α)$ superconformal group. This invariance is not evident and is achieved within modified (super)conformal transformations of the superfields.

Scenery to wilderness: National park development in Tasmania, 1916-1992
Creators: name: Mendel, LC
Publisher: name: University Of Tasmania
Year: 2023

description: National parks comprise a significant component of landscapes around the world. This thesis examines the development of the national park system in Tasmania from 1916 to 1992, with a particular emphasis on changing conservation motives and themes, and their expression in the reserve system. Part One of this thesis traces the creation of national parks in Tasmania over three major periods of reservation activity: the early period (1916- 1937); the middle period (1938-1970); and the late period (1971-1992). Historical evidence is used to identify: the reserve proponents and their motives; opposition to establishing reserves; the debates surrounding the creation of reserves; and the outcomes. A developmental narrative is given on the creation of national parks in each period, with a broader view of identifying the dominant conservation motives and themes and changes to these over time. Part Two of this thesis examines the representation of three majo r conservation attributes in national parks established across each period of reserve development. The representation of biological diversity, scenery and wilderness in national parks is quantified for each period. The changing levels of representation of each of these attributes and their relative significance to each other over time are assessed. The historical and mapping analyses both indicate that there have been shifting emphases in conservation motives and themes over time in the development of Tasmanian national parks. In both the early and middle periods the historical evidence suggests that scenery and general nature conservation were the dominant motives behind the creation of national parks, together with themes of tourism and recreation. In the late period there was a shift in emphasis towards wilderness conservation and more spe cific nature conservation as the dominant themes. Areas of high aesthetic value had greater proportionate representation in national parks during the early and middle periods than the late period. While national parks were established in wild erness areas during all periods, the representation of wilderness in the reserve system increased dramatically during the late period. The representation of biological diversity was biased towards high altitude biological elements in the early and middle periods, and expanded to capture greater diversity during the late period. There is thus a strong relationship between motives and p atterns of elements captured in the reserve system. However, this has been tempered by opposition from those with economic interests in the State's natural resources, particularly the mining, forestry and hydroelectric industries.

description: Since its beginning well over a quarter of a century ago, the Vocational Agriculture program has become an integral part of the American school system. The legislative groundwork for Vocational Agriculture, as well as all other vocational programs, was set in 1917 with the passing of the Smith-Hughes Act. Further related legislation was passed in 1929 and 1934, but the program received its greatest federal boost with the passing of the George-Deen Act in 1936 and the George-Barden Act in 1946, both of which provided for the annual expenditure of federal funds in support of vocational education. The George-Barden Law, although it includes appropriations from the former bill, provides a total of approximately $29,000,000 for the support of vocational education. This is the maximum. allowance, however, am all of it will not be expended unless an actual need exists. With the $7,200,000 appropriated under the original Smith-Hughes Law, the total authorization available now reaches approximately $36,050,000 with agriculture being allocated $13,000,000 of this amount. This includes only the federal provisions. In agriculture alone the total expenditures from federal, state, and local sources increased from $21,293,343 in 1946 to $47,490,397 in 1953. (3, p. 10)

description: Phase change materials that have low thermal conductivity take a longer time to store and to discharge the stored thermal energy. The thermal conductivity of phase change materials can be enhanced using different additives. Beeswax is a phase change material with a high thermal capacity and low thermal conductivity. Therefore, the thermal conductivity, melting temperature, latent heat, and heat capacity of beeswax incorporating ZnO, CuO and soot particles with the 0.0, 0.064, 0.326, 1.304, and 3.260 g in the 20 g beeswax have been studied. The thermal conductivity measurement shows that the incorporation of ZnO, CuO and Sootparticles improved the thermal conductivities of the beeswax, i.e., from 0.2502W/mK to 2.89W/mK. Moreover, the differential scanning calorimetry measurements revealed that the melting temperature, latent heat, and heat capacity of the beeswax are decreased because of the incorporation of ZnO, CuO and Soot particles. Therefore, it is possible to tune the thermal properties of the beeswax incorporating metal oxide, soot particles to use beeswax-metal oxide/soot composite as a phase change materials.

description: This paper examines a comparative view of the inflation dynamics in three African countries. The study used monthly data from January 2007 to April 2018. To achieve the objectives, the study was deployed varieties of econometric methods. The exploratory analysis reveals that inflation of the sampled countries exhibits similar trends over the long run. The Johansson Co-integration test result evince that inflation, oil price and exchange rate of Ethiopia and South Africa had a long run relationship. Exchange rates had significant positive effects on inflation dynamics of both countries while world oil price contributes positively in Ethiopia but negatively in South Africa. In the short run, inflation in Kenya was found to be a sign of Ethiopia’s inflation. Likewise, in South African inflation was an indicator of the inflation in Kenya whereas inflation in Kenya and Ethiopia could not predict inflation would occur in South Africa. Furthermore, the outcome of the impulse response function demonstrates that exchange rates and oil price shocks affected inflation dynamics of the sampled countries at different stages both directly and indirectly. In the short run, shocks to inflation have an interaction effect across the selected countries. The findings also report that world oil prices are not equally contributes for inflation dynamics in the sampled countries.

description: This paper presents results on event-by-event elliptic flow fluctuations in Au+Au collisions at sqrt(s_NN)=200Gev, where the contribution from non-flow correlations has been subtracted. An analysis method is introduced to measure non-flow correlations, relying on the assumption that non-flow correlations are most prominent at short ranges (Delta eta < 2). Assuming that non-flow correlations are of the order that is observed in p+p collisions for long range correlations (Delta eta > 2), relative elliptic flow fluctuations of approximately 30-40% are observed. These results are consistent with predictions based on spatial fluctuations of the participating nucleons in the initial nuclear overlap region. It is found that the long range non-flow correlations in Au+Au collisions would have to be more than an order of magnitude stronger compared to the p+p data to lead to the observed azimuthal anisotropy fluctuations with no intrinsic elliptic flow fluctuations.

description: Surface topographies at micro- and nanoscales can influence different cellular behavior, such as their growth rate and directionality. While different techniques have been established to fabricate 2-dimensional flat substrates with nano- and microscale topographies, most of them are prone to high costs and long preparation times. The 2.5-dimensional fiber platform presented here provides knowledge on the effect of the combination of fiber alignment, inter-fiber distance (IFD), and fiber surface topography on contact guidance to direct neurite behavior from dorsal root ganglia (DRGs) or dissociated primary neurons. For the first time, the interplay of the micro-/nanoscale topography and IFD is studied to induce linear nerve growth, while controlling branching. The results demonstrate that grooved fibers promote a higher percentage of aligned neurite extension, compensating the adverse effect of increased IFD. Accordingly, maximum neurite extension from primary neurons is achieved on grooved fibers separated by an IFD of 30 μm, with a higher percentage of aligned neurons on grooved fibers at a large IFD compared to porous fibers with the smallest IFD of 10 µm. We further demonstrate that the neurite “decision-making” behavior on whether to cross a fiber or grow along it is not only dependent on the IFD but also on the fiber surface topography. In addition, axons growing in between the fibers seem to have a memory after leaving grooved fibers, resulting in higher linear growth and higher IFDs lead to more branching. Such information is of great importance for new material development for several tissue engineering applications. Statement of Significance: One of the key aspects of tissue engineering is controlling cell behavior using hierarchical structures. Compared to 2D surfaces, fibers are an important class of materials, which can emulate the native ECM architecture of tissues. Despite the importance of both fiber surface topography and alignment to direct growing neurons, the current state of the art did not yet study the synergy between both scales of guidance. To achieve this, we established a solvent assisted spinning process to combine these two crucial features and control neuron growth, alignment, and branching. Rational design of new platforms for various tissue engineering and drug discovery applications can benefit from such information as it allows for fabrication of functional materials, which selectively influence neurite behavior. © 2020

description: Three months after the 2nd September 2008 election, Vanuatu was still without a stable government. In the wake of the September polls, there was intense manoeuvring by the major parties involving accusations of 'member stealing' and allegations of the exchange of large sums of money to secure support. A government led by Edward Natapei was formed on September 22 based upon a coalition between the Vanua'aku Pati (VP) and the National United Party (NUP). With a slim 27 to 25 majority in the country's 52 seat Parliament, the new government immediately faced a succession of 'no confidence' challenges, each moved by frustrated opposition MPs who had missed out on positions in cabinet.

description: It is evident that guidance and counselling service disentangles students’ educational, vocational, personal, and social problems. The main objective of this study was to explore the current status of guidance and counselling service in Adama Science and Technology University (ASTU) and Addis Ababa Science and Technology University (AASTU). By setting relevant criteria, the study attempted to identify the most appropriate model of guidance and counselling services for the study population. The main sources of information were six guidance personnel and 333 graduating students of the two universities. The guidance personnel were purposefully included in the study, while the students were selected randomly. To gather information from the respondents, questionnaires with open ended questions and Likert scale type were developed based on the theories and circumstances affecting the provision of guidance and counselling in Ethiopia. Interviews with guidance and counselling unit heads were also used to substantiate the data obtained through the questionnaires. In the analysis of data, qualitative description of information from the open-ended questions and interviews and quantitative interpretation of data obtained from closed-ended questions and converted to statistics such as frequency and percentage were employed. The study reveals that there is lack of awareness among the student population on the availability of guidance and counselling service in their campus and its benefits. It also highlights that there is lack of confidence in guidance and counselling service personnel to solve students’ academic, career, personal, social, and psychological problems. Overall, there is low status of guidance and counselling service in alleviating students’ problems On the basis of the findings, some criteria in the selection of a model relevant to the Ethiopian context were set. A model was developed and reviewed for two rounds by experts before it is taken for granted. Suggestions for further investigation were also made.

Non-Parametric Analysis for the Dark Matter Density Evolution

description: In this paper, we investigate a potential departure in the standard dark matter density evolution law, $ρ_{dm} = ρ_{dm,0}(1+z)^3$. The method involves considering a deformed evolution model, denoted as $ρ_{dm} = ρ_{dm,0}(1+z)^3f(z)$, and searching the presence of any deviation ($f(z)\neq 1$). As one may see, $f(z)$ is a general function that parametrizes a possible digression from the standard law. We use data of baryon acoustic oscillations, type I Supernovae luminosity distances, and galaxy cluster gas mass fraction observations to reconstruct $f(z)$ through an approach that is not dependent on the cosmological model or the so-called Gaussian process regression. Unlike previous works, it enables us to investigate a possible deviation without using a specific function to describe it. We have obtained $f(z)=1$, the standard model scenario, within $2σ$ c.l. in all the considered cases.
