Mathematics achievement at the sixth-grade in Israel
Creators: name: Mokatrin, Saleem Mohammed
Publisher: name: American University
Year: 2023

description: The purpose of this study was to determine whether or not a gap between Arab and Jewish students in Israel exists, and, if so, to describe the nature of that gap. Specifically, the extent to which socioeconomic factors seem to be associated with mathematics performance and achievement at the sixth grade level was examined. The study included two major groups of independent variables--pupil characteristics and teacher characteristics--and one dependent variable--the achievement test outcome. The 400 students who participated in the study were selected from fourteen Israeli schools. This sample was composed of two groups: 210 Arabs and 190 Jews. The three instruments used for the collection of data were the pupil's questionnaire, the mathematics achievement test, and the teacher's questionnaire. This study found that overall there was a significant difference between the Arab and Jewish students' mean scores on the mathematics achievement test. The variable of student's sex did not result in a significant difference in test scores. When the effect of the place of birth variable was tested, the results showed that overall, immigrants performed better than the students born in Israel. But there was no statistically significant difference in the performance of the Jewish groups regardless of whether or not the students were born in Israel. The findings showed that the variables: family size, father's and mother's education, father's and mother's occupation, the teacher's degree, teacher's mathematics degree, and teacher's sex were significant in terms of the entire sample.

description: In 1999-200, 'Bangladesh exported about 197.92 million sft. of leather and leather goods and earned about 249.93 million US dollar. The growth rate of leather export during 1981-82 to1989-90 and 1990-91 to 1999-2000 were 3.52% and 4.88%, respectively with an average of 4.14%.. It revealed that during 1990-91 to 1999-2000, the annual growth rate of leather goods and leather shoes were 22.03% and 31.17%, respectively. At present, the export consists of 60-65% crushed leather, 25-30% finished leather and 5-8% leather goods and leather shoes. Since 1947, many good proposals were made in government development plans and policies but a very few of them were materialised. Hides and skins are highly value-added resources of Bangladesh. The value additions are higher in 'crust' leather and 'finished' *leather by 40-45% and 80-100%, respectively than 'wet-blue' leather. This implied that there is a great potentiality .of doubling the foreign exchange earnings by value additions. But this sub-sector is beset with many problems. Those were: thickness and defects in hides and skins, slow modernisation process of tanneries, acute shortage of trained manpower, lack of Footwear Design and Development Institute and Bangladesh College of Leather technology and Leather Research Centre are not operative autonomously. To overcome those problems, establishment of 'Bangladesh Leather Development Council' is suggested.

The effect of collaborative writing on cohesion in poetry therapy groups
Creators: name: Golden, Karina Marie
Publisher: name: American University
Year: 2023

description: The use of poetry as a therapeutic technique has evolved into a creative arts therapy known as poetry therapy. Poetry therapy has been used as a therapeutic technique to enhance cohesion. Ross (1974) and Mazza (1981) both used the Group Environment Scale (Moos and Hanson, 1974) as a pretest and posttest measure of group cohesion and discovered that poetry therapy scores on the posttests were significantly greater in poetry therapy groups than those in non-poetry groups. Mazza indicated that the use of collaborative writing in the poetry therapy groups was identified by participants as an aid to feelings of cohesion. The purpose of this study was to build on previous research conducted on poetry therapy and cohesion by isolating the variable of collaborative writing and comparing control groups without collaborative writing and experimental groups with collaborative writing on the Group Environment Scale. The subjects in this study were 33 graduate students in an intact Group Counseling class at an urban university were randomly assigned to treatment and control groups. The treatment for the control group consisted of six sessions of poetry therapy without collaborative writing. The experimental groups received six sessions of poetry therapy with collaborative writing. A t-test was used to compare control and experimental posttest scores on the Group Environment Scale. The comparison revealed that there was a significant difference (p $<$.05) between posttest scores in poetry therapy groups with collaborative writing. Therefore the hypothesis that there would be a significant difference between control and experimental groups was accepted. This study supports previous research on the effect of poetry therapy and collaborative writing as ways of increasing cohesion in therapy groups.

description: We discuss the possibility that gravitational fluctuations ("gravitational-waves") are trapped in space by gravitational interactions in two dimensional Jackiw-Teitelboim gravity. In the standard geon (gravitational electromagnetic entity) approach, the effective energy is entirely deposited in a thin layer, the active region, that achieves spatial self-confinement and raises doubts about the geon's stability. In this paper we relinquish the "active region" approach and obtain self-confinement of "gravitational waves" that are trapped by the vacuum geometry and can be stable against the backreaction due to metric fluctuations.

description: Abstract: The hydrological characteristics of the upper reaches of the Iskar River are distinguished by significant fluctuations and pronounced seasonality. In these sections of the river an anthropogenic pressure have been detected, which affected on the ecological situation of the aquatic ecosystem. The aim of the research paper was to analyse hydrological characteristics and physico-chemical parameters of the waters at the upper part of the Iskar River. Hydrological data from the conducted own measurements in selected representative sites were collected. An analysis of the water level, water quantity changes for the period 2015-2020 and water balance estimation was made. Water samples from the selected representative sites in the upper part of Iskar River were taken. Water temperature, pH, dissolved oxygen/saturation and conductivity were measured. Ecological status of the studied sites according to the values of the basic physicochemical parameters of the lotic ecosystem was assessed.

An Investigation into the Use of Sit-to-Stand Desks on the University of British Columbia Campus

Publisher: name: The University of British Columbia
Year: 2017

description: This report has been prepared in response to an assignment for APSC 262, a course offered at the University of British Columbia. The purpose of this assignment is to investigate the feasibility of installing sit-to-stand desks on the university’s campus and to recommend whether and to what extent the university should install sit-to-stand desks on its campus. The scope of this report is constrained to only the University of British Columbia staff and faculty. This report does not assess the feasibility or appropriateness of providing University of British Columbia students with sit-to-stand desks. Overwhelming evidence shows that sit-to-stand desks improve office comfort and in some cases office productivity. Those who possess a medical need for a sit-to-stand desk typically demonstrate considerable improvement in physical health after using one for an extended period of time. Many office workers experience neck and back pain due to long uninterrupted periods of sitting. Sit-to-stand desks help users alleviate back and neck pain by allowing the user to stand for a portion of the day. There are many studies that have corroborated these statements. The authors of this report recommend that sit-to-stand desks be provided to UBC faculty and staff who request them or have a medical need for which a sit-to-stand desk would provide medical assistance. Due to the high costs of sit-to-stand desks and the possibility that many university staff and faculty would not benefit from sit-to-stand desks, the authors believe that providing all university staff and faculty with sit-to-stand desks is exorbitant and wasteful. However, the authors believe that providing those staff and faculty who exhibit medical necessity with sit-to-stand desks will improve office comfort and productivity for these staff and faculty. In addition, the authors recommend that the university adopt this policy regarding sit-to-stand desks on a trial basis. During the trial period, the university should collect statistics about the use of its sit-to-stand desks and after the completion of the trial period, which the authors recommend to be one year long, the authors recommend that the university should reassess the integrity of the policy.

description: This paper investigates economics of homestead forestry and household fuel use pattern in some areas of Bangladesh. Average size of homestead area was 0.06 ha and average number of forest trees was 1.24, fruit plants 2.07 and bamboos 18.16. Per farm average annual return from the forest plants was Tk.2389.3 per farm and it accounted for 12.67 percent of the total farm income. All the farms used home supplied firewood, dry leaves of trees, cow-dung cakes, paddy stalk and straw as household fuel. The paper identifies a number of constraints to further development of homestead forestry. Finally, some measures are suggested in the study.

title: The Immune Response in Canine Atopy: hypersensitivity to house dust mites ['Dermatophagoides spp.']
Creators: name: Shaw, Stephen Charles
Publisher: name: The Open University
Year: 2000

description: The genetic and immunological basis of canine atopic dermatitis (CAD), a hypersensitivity disease to environmental allergens in dogs, was investigated.

The evaluation of the clinical records of 434 dogs belonging to 92 litters related to dogs with CAD showed that the disease was greatly dependent upon genetic influences with a heritability of 0.49. Using a highly specific IgE detection reagent (FcƐRl alpha-chain) Dermatophagoides pteronyssinus (DP) -specific IgE was measured in the serum of normal and atopic dogs by ELISA. Dogs with CAD had significantly more DP-specific IgE than non- atopic dogs (p<0.0001).

Immunoblotting revealed that the serum IgE response to DP in CAD was dominantly to three polypeptides with apparent molecular weights of 34, 63 and 89-95kDa. The 89- 95kDa polypeptide has been characterised as a mite chitinase. Cellular immune responses to DP extract were measured in normal and atopic dogs by measuring the antigen-specific proliferation of peripheral blood mononuclear cells. Atopic dogs showed greater proliferative responses to DP than normal dogs, although there was large individual variation.

Dogs were immunised with DP extract to help identify the approximate molecular weights of allergens containing the dominant T-cell epitopes. The lymphocyte proliferative responses to DP polypeptides purified by SDS-PAGE were greatest to proteins of between 60 and 90kDa, similar in size to those reacting with serum IgE in dogs with CAD.

 Clinical and laboratory examination of dogs with allergic conjunctivitis showed that this condition was associated with CAD. Histopathological examination of conjunctival tissue often revealed signs of allergic response. However, IgE was not detected in the tears of enough affected dogs for it to be diagnostically useful.

 Family genetic studies and selective breeding programmes can significantly reduce the numbers of animals suffering from CAD. This study has identified antigens which should be used as the basis of improved CAD diagnostic and therapeutic reagents.

description: It is shown in a recent preprint [arXiv:2001.10008] that the central spin model with XX-type qubit-bath coupling is integrable for a central spin $s_0=1/2$. Two types of eigenstates, separable states (dark states) and entangled states (bright states) between the central spin and the bath spins, are manifested. In this work, we show by using an operator product state approach that the XX central spin model with central spin $s_0>1/2$ and inhomogeneous coupling is partially solvable. That is, a subset of the eigenstates are obtained by the operator product state ansatz. These are the separable states and those entangled states in the single-spin-excitation subspace with respect to the fully polarized reference state. Due to the high degeneracy of the separable states, the resulting Bethe ansatz equations are found to be non-unique. In the case of $s_0=1/2$ we show that all the separable and entangled states can be written in terms of the operator product states, recovering the results in [arXiv:2001.10008]. Moreover, we also apply our method to the case of homogeneous coupling and derive the corresponding Bethe ansatz equations.

description: It has previously been reported that subjects trained to discriminate either the mu antagonist naloxone or mu agonist morphine from its vehicle generalized stimulus control to nalorphine, effects presumably due to nalorphine's intermediate efficacy at the mu opiate receptor subtype. In an attempt to assess the efficacy of nalorphine relative to naloxone (none) and morphine (high), subjects were trained within the taste aversion baseline of drug discrimination learning to respond differentially to naloxone and morphine in a two-drug discrimination procedure. Following the acquisition of the discrimination, nalorphine, as well as the mu agonists methadone and buprenorphine, produced morphine-appropriate responding, while the mu antagonists naltrexone and diprenorphine produced responding appropriate for naloxone. These data suggest that when the relative efficacy of nalorphine is examined, nalorphine lies closer to morphine than naloxone along the continuum of relative efficacy (Experiment 1). Given that in Experiment 1 nalorphine substituted for morphine-trained subjects, but not to naloxone-trained subjects, it was expected that when subjects were trained to discriminate nalorphine from vehicle, nalorphine would generalize this control to morphine but not to naloxone or naltrexone (Experiment 2). Following acquisition of the discrimination, nalorphine stimulus control generalized completely to morphine in five of six subjects, while with the exception of a single subject, naltrexone and naloxone failed to do so. The broad-based opiate antagonist diprenorphine also engendered nalorphine-appropriate responding in all subjects. That nalorphine generalized to morphine but not to naloxone or naltrexone, is consistent with the expectation that nalorphine is a partial agonist at the mu receptor with efficacy closer to morphine than to naloxone. That diprenorphine substituted for nalorphine suggests that diprenorphine, like nalorphine, possesses partial agonist activity. From the present studies, it is suggested that opiates lie on a continuum of efficacy ranging from no efficacy to maximum efficacy and that they can be rank ordered in terms of their relative intrinsic effects: $\rm naloxone\le naltrexone

description: We perform a weak lensing analysis on a previously reported dark-lens candidate on STIS Parallel data (Miralles et al. 2002). New VLT-data indicate that the reported signal originates from a small number of galaxies tangentially aligned towards the center of the STIS field but no signature for an extended mass distribution is found. We argue that we should be able to detect a massive cluster ($M\geq 3.2\times 10^{14}M_{\odot}$) through its lensing signal up to a redshift of $z\approx 0.6$ with our data. Also the double image hypothesis of two galaxies with very similar morphologies in the STIS data is ruled out with colour information.

description: This study surveyed the impact of power tiller use on employment, productivity and equity aspects in the agrarian community. It covered 180 households taking 60 from each of the three selected thanas of Mymensingh district considering the intensity of power tiller use by a multi-stage stratified random sampling and the entire 53 power tillers were studied in the sample villages. The use of power tiller induced significant incremental (25%) hired labor though a portion (6%) of human labor was replaced. On an average 203 man-days were used for per hectare Boro rice production of which 44.80% were family labor, 28.45% and 26.75% were casual and contract labor respectively. Except the rental cost of power tiller in Trishal, the other inputs did-not differ significantly among the locations which influenced the profitability of producing Boro in different areas. The per hectare highest gross return and gross margin .(Taka 32,036 and Taka 10,661) was found in Trishal followed by Muktagacha (Taka 30,710 and Taka 9,889); The net return was found negative in Gouripur and marginal net return was observed in Trishal and Muktagacha. The returns over per Taka investment on full cost basis were Taka 1.11, 1.10 and 0.88 for Trishal, Muktagacha and Gouripur respectively which indicated that the less power tiller users were greater losers than those who used them intensively. The BCR and NPV of the new power tillers were found L26 .and Taka 39,245 and for the old one 1.25 and Taka 30,199 respectively. Nevertheless, IRR was found to be 79.58% and 158.37% for the new and old power tillers respectively. Most of the medium farmers owned power tillers and their.lands were tilled by such technology. The land conceritration ratios were 0.29, 0.35 and 0.27 in Trishal, Muktagacha and Gouiipur respectively. The income concentration ratios were 0.25, 0.36, and 0.40 in the three areas which indicated that the intensive use of power tillers reduced income inequalities.

description: In this study, we make an attempt to assess how the food composition of the Marsh Frog (Pelophylax ridibundus) populations from anthropogenically polluted areas, is affected and what changes in the diet, can be affiliated with environmental pollution. We examined the trophic spectrum of individuals from three populations – two polluted areas (Site 1 - the Chaya River near the confluence with the Maritza River, where the river receives industrial wastewaters and Site 2 – Tsalapitsa Rice Fields near Plovdiv City) and one reference site (control) at Vacha River, south of the town of Krichim (located in a protected zone that is far from industrial or agricultural human activity). The stomach contents were collected by using the stomach flushing method, the stomach contents of 60 (30 males, 30 females) adult individuals were studied. The diet of the population of the Marsh Frog (Pelophylax ridibundus) from the control area – Krichim Town can be characterized with more numerous prey categories and prey taxa, while the trophic spectrum from the other two polluted areas (KCM – wastewaters from heavy metals production and Tsalapitsa Rice Fields – fertilizers and pesticides use) consists of significantly less numerous prey taxa. The trophic niche breadth is also larger at the reference site (12.10) and has lower values at the two polluted sites.

description: We have analysed the kinematics of a sample of 114 hot subdwarf stars, for 2/3 of which we present new proper motions, spectroscopic and photometric data. The vast majority of the stars show a kinematic behaviour that is similar to that of Thick Disk stars. Some stars have velocities rather fitting to solar, i.e. Thin Disk, kinematics. 16 objects have orbital velocities which differ considerably from those of Disk stars. These are members of the Galactic Halo. We analysed the velocity dispersions and calculated orbits. Most stars feature orbits with disk character (eccentricity <= 0.5), a few reach far above the Galactic plane and have very eccentric orbits (ecc >= 0.7). The intermediate eccentricity range is poorly populated. This indicates that the (Thick) Disk and the Halo are kinematically disjunct. Plotting a histogram of the orbit data points along z leads to the z-distance probability distribution of the star; doing this for all stars leads to the z-distance probability distribution of the sample. The logarithmic histogram shows two slopes, each representing the scale height of a population. The disk component has a scale height of 0.9 (0.1) kpc, which is consistent with earlier results and is similar to that of the Thick Disk. The other slope represents a component with a scale height ~7 kpc, a much flatter gradient than for the disk component. This shows that the vast majority of the sdBs are Disk stars, but a Halo minority is present, too. The kinematic history and population membership of the sdB stars on the whole is different from that of the cooler HBA stars, which are predominantly or even exclusively Halo objects. This leads to the question, whether the Halo sdB stars are of similar origin as the HBAs, or whether their kinematical behaviour possibly represents another origin, such as infalling stellar aggregates.

A neuropsychological investigation of adults disabled by autism: Consequences of autism and mild mental retardation
Creators: name: Belcher, Ronald G.
Publisher: name: American University
Year: 2023

description: This investigation examined three prominent theories concerning the etiology of autism. Study 1 used several neuropsychological tests to evaluate the left hemisphere dysfunction hypothesis in autism. Tests of cerebral lateralization included a handedness assessment, dichotic listening tests, a stereognosis test, and face perception tests. Study 2 used a problem-solving test, a design fluency test, and tests of word fluency to evaluate abilities associated with frontal lobe functions. Study 3 used a variety of memory tests to assess memory abilities in autism. Memory tests included verbal and visual paired associates, recall of a previously-drawn complex figure, recall of digit series and of visual-spatial sequences, and recognition memory for geometric and nonsense figures. Twenty subjects with autism and twenty control group subjects were matched on age and verbal intelligence. Subjects were divided into two groups based on verbal intelligence, namely, a high functioning group with borderline to average cognitive functioning and a low functioning group with mild retardation. Two groups of subjects were used to examine the impact of autism alone and of autism and mental retardation together on neuropsychological functioning. Mann-Whitney U tests and Fisher exact probabilities were used to analyze data for differences between subjects with autism and matched control group subjects. Study 1 uncovered evidence for reduced cerebral lateralization for language only in subjects with autism who also had mild mental retardation. This result suggests that these subjects sustained bilateral cerebral dysfunction. There was no evidence of a left hemisphere dysfunction in high functioning subjects with autism. Study 2 revealed significant impairments on tests associated with frontal lobe functions for subjects with autism. Finally, Study 3 revealed no memory impairments associated with autism, relative to control group subjects. This result argues against an autism-amnesia parallel or temporal lobe dysfunction. Results are discussed in light of current theorization on the etiology of autism which emphasizes multiple overlapping dysfunctions and cortical-subcortical interconnections. Directions for future research are suggested.

description: In this study, an attempt was made to analyse the productivity of subsidised and non-subsidised dairy farms for determining the income effect of subsidy provided to the dairy farmers by the government of Bangladesh. For this purpose, a sample of 200 subsidised ande200 non-subsidised dairy farms in 6 regions of the country were purposively interviewed with a pre-tested interview schedule. The results indicated that number of milk cows, concentrate feed cost, labour cost, veterinary cost and miscellaneous cost are the most determinant factors for the dairy production in study areas. The coefficients,of multiple determinant (R2) of subsidised dairy farms (SDF) and non-subsidised dairy farms (NSDF) in the output of dairy income showed, 75 and 74 percent variation, respectively. The sum of the elasticities of production showed a more or less constant return to kale both for SDF and NSDF, indicating that subsidization could not financially influence the generation of income in dairy farming.

description: Benchmarking is crucial for evaluating a DBMS, yet existing benchmarks often fail to reflect the varied nature of user workloads. As a result, there is increasing momentum toward creating databases that incorporate real-world user data to more accurately mirror business environments. However, privacy concerns deter users from directly sharing their data, underscoring the importance of creating synthesized databases for benchmarking that also prioritize privacy protection. Differential privacy (DP)-based data synthesis has become a key method for safeguarding privacy when sharing data, but the focus has largely been on minimizing errors in aggregate queries or downstream ML tasks, with less attention given to benchmarking factors like query runtime performance. This paper delves into differentially private database synthesis specifically for benchmark publishing scenarios, aiming to produce a synthetic database whose benchmarking factors closely resemble those of the original data. Introducing \textit{PrivBench}, an innovative synthesis framework based on sum-product networks (SPNs), we support the synthesis of high-quality benchmark databases that maintain fidelity in both data distribution and query runtime performance while preserving privacy. We validate that PrivBench can ensure database-level DP even when generating multi-relation databases with complex reference relationships. Our extensive experiments show that PrivBench efficiently synthesizes data that maintains privacy and excels in both data distribution similarity and query runtime similarity.

description: We provide a Lie algebra expansion procedure to construct three-dimensional higher-order Schrödinger algebras which relies on a particular subalgebra of the four-dimensional relativistic conformal algebra. In particular, we reproduce the extended Schrödinger algebra and provide a new higher-order Schrödinger algebra. The structure of this new algebra leads to a discussion on the uniqueness of the higher-order non-relativistic algebras. Especially, we show that the recent d-dimensional symmetry algebra of an action principle for Newtonian gravity is not uniquely defined but can accommodate three discrete parameters. For a particular choice of these parameters, the Bargmann algebra becomes a subalgebra of that extended algebra which allows one to introduce a mass current in a Bargmann-invariant sense to the extended theory.

description: This study examines the comparative profitability of both deep and shallow tubewell irrigation technology. Regarding this, 3 DTWs and 11 STWs were randomly selected for farm survey. Kharera union of Kasba upazila of Brahmanbaria district was selected purposively. Data were collected during the period of February 2000 to July 2000. Tabular method of analysis as well as financial analysis and sensitivity analysis were applied. Evidence shows that investment in STWs was found to be profitable especially electrically operated STWs were more profitable than diesel operated STWs. While the DTW operation appeared as a loosing concern from the owners' point of view. Results of the sensitivity analysis suggested that the investments in diesel operated STWs were in break-even level with 20 per cent increase in operation and maintenance cost while electrically operated STWs were in break-even level with 15 per cent decrease in gross benefits, other things remaining the same. The result of sensitivity analysis also suggested that with 15 per cent decrease in gross benefit investments in diesel operated STWs were incurring loss. Thus, the investments in tubewell operation was largely affected either by increase in operation and maintenance cost or by decrease in water price. Finally, based on the above findings of the study, some recommendations were suggested for policy implication.
