description: THE College, in common with the other two Scottish Agricultural Colleges, is collaborating with the Department of Agriculture for Scotland in a programme of investigation into the economic position of agriculture through the study of the financial accounts of farms. The objects of this work are to place in the hands of the Colleges material on which to base an economic advisory service for the benefit of the farmers in their areas, and at the same time to permit the Department to assess with some accuracy the economic status of the various forms the industry takes, with a view to the consideration of agricultural policy. As an advisory method, such work is in its infancy in this country. It is being developed extensively in the *United States of America, particularly in Illinois, and has been used, to some extent, in our own country in the Bristol province.

description: Research background: The motive behind intentional non-microbiological contamination or adulteration of foods is to limit costs, enhance competitiveness, and increase profits. Profits motivate entrepreneurs and costs caused by operating a quality assurance program that is not offset by revenue increases are resisted. Purpose of the article: To understand the constraints preventing companies from having quality assurance programs, this study examines differences in importance of various constraints in three food industry sub-sectors in Shanghai, China. Methods: The study applies the own survey data because there is a lack of readily available data on the selected topic. A total of 199 food company representatives completed a questionnaire during a workshop on food regulations between September and December, 2016. Descriptive statistics and the heteroskedasticity corrected regression technique are applied to identify statistically significant factors. Findings & Value added: Results show that perishable food sub-sector companies more often agreed that constraints were important in limiting quality assurance programs as compared to the non-perishable food sub-sector. A company anticipating a decrease in revenues in the three years following the survey (2017-2019), employing seasonal workers, and represented by a middle level manager was more likely to view constraints as barriers. Although Shanghai is a large commercially area, the study does not include companies from other provinces recognizing that some regional specificity may matter in implementing quality assurance program. The identified factors suggest the role for government agencies in facilitating such implementation by offsetting selected costs associated with the process of adopting a quality assurance program, while the society at large learns about factors motivating or hampering the implementation of quality assurance programs by food manufacturing companies. This study fills the void in the literature and provides insights about the constraints faced a company generating knowledge for regional and national regulators useful in choosing subsectors and specific aspects facilitating food quality program implementation.

description: Because the assumption of normality is common in statistics, the robustness of statistical procedures to the violation of the normality assumption is often of interest. When one examines the impact of the violation of the normality assumption, it is important to simulate data from a nonnormal distribution with varying degrees of skewness and kurtosis. Fleishman (1978, Psychometrika 43: 521–532) developed a method to simulate data from a univariate distribution with specific values for the skewness and kurtosis. Vale and Maurelli (1983, Psychometrika 48: 465–471) extended Fleishman’s method to simulate data from a multivariate nonnormal distribution. In this article, I briefly introduce these two methods and present two new commands, rnonnormal and rmvnonnormal, for simulating data from the univariate and multivariate nonnormal distributions.

description: The Bayesian optimal interval (BOIN) design is a novel phase I trial design for finding the maximum tolerated dose (MTD). With the BOIN design, phase I trials are conducted as a sequence of decision-making steps for assigning an appropriate dose for each enrolled patient. The design optimizes the assignment of doses to patients by minimizing incorrect decisions of dose escalation or deescalation; that is, it decreases the chance of erroneously escalating or de-escalating the dose when the current dose is higher or lower than the MTD. This feature of the BOIN design strongly ensures adherence to ethical standards. The most prominent advantage of the BOIN design is that it simultaneously achieves design simplicity and superior performance in comparison with similar methods. The BOIN design can be implemented in a simple way that is similar to the 3 + 3 design, but it yields substantially better operating characteristics. Compared with the well-known continual reassessment method, the BOIN design yields average performance when selecting the MTD, but it has a substantially lower risk of assigning patients to subtherapeutic or overly toxic doses. In this article, we present a command (optinterval) for implementing the BOIN design in a phase I clinical trial setting.
NEW TECHNIQUES FOR DISCRIMINATION WITH NOMINAL LEVEL VARIABLES
Creators: name: Matthews, Peter Felix
Publisher: name: American University
Year: 2023

description: The basic discriminant analysis problem is as follows: Assume there are two distinct populations. A random sample is drawn from each of the two populations, and various characteristics are measured for each member of both samples. The aim is to use observed differences in the characteristics between the two groups as a means of predicting population membership of new observations. Practical examples of this problem include the identification of eligible versus ineligible welfare recipients or correct versus incorrect tax returns. The classical statistical methods developed to deal with this problem tend to make unduly restrictive assumptions about the nature and distribution of the population characteristics. In particular, assumptions of multivariate normality, linearity, additivity, and order of interactions are involved. The dissertation shows that these assumptions are often inappropriate and unnecessary, especially when dealing with characteristics measured at the nominal level. A new class of procedures based on a general sequential algorithm is defined. These procedures are shown to be the discrete equivalent of sequential regression procedures. The new procedures are compared to Fisher's linear (and quadratic) discriminant analysis procedures on a set of actual problems drawn from the literature and are found to perform as well as, or better than, Fisher's approach in every case. In addition, a detailed example is carried out using data from the New Hampshire Medicaid program. In this case, a post-test sample was used to demonstrate the validity of the results. The new methods were found to work equally well on the new sample. Furthermore, the results were superior to those achieved by other methods applied to similar data. Thus, it is concluded that this new class of sequential algorithms represents a viable alternative to the usual methods of discriminant analysis, particularly if the researcher is concerned about the validity of the assumptions underlying those methods.

description: Group IV and V monolayers are very crucial 2D materials for their high carrier mobilities, tunable band gaps, and optical linear dichroism. Very recently, a novel group IV-V binary compound, Sn2Bi, has been synthesized on silicon substrate, and has shown very interesting electronic properties. Further investigations have revealed that the monolayer would be stable in freestanding form by hydrogenation. Inspired by this, by means of first-principles calculations, we systematically predict and investigate eight counterparts of Sn2Bi, namely Si2P, Si2As, Si2Sb, Si2Bi, Ge2P, Ge2As, Ge2Sb, and Ge2Bi. The cohesive energies, phonon dispersions, and AIMD calculations show that, similar to Sn2Bi, all of these freestanding monolayers are stable in hydrogenated form. These hydrogenated monolayers are semiconductors with wide band gaps, which are favorable for opto-electronic purposes. The Si2YH2 and Ge2YH2 structures possess indirect and direct band gaps, respectively. They represent very interesting optical characteristics, such as good absorption in the visible region and linear dichroism, which are crucial for solar cell and beam-splitting devices, respectively. Finally, the Si2SbH2 and Si2BiH2 monolayers have suitable band gaps and band edge positions for photocatalytic water splitting. Summarily, our investigations offer very interesting and promising properties for this family of binary compounds. We hope that our predictions open ways to new experimental studies and fabrication of suitable 2D materials for next generation opto-electronic and photocatalytic devices.

description: (Abridged) A simple and general description of the dynamics of a narrow eccentric ring is presented.We view an eccentric ring which precesses uniformly at a slow rate as exhibiting a global $m=1$ mode originating from a standing wave superposed on an axisymmetric background.We adopt a continuum description using the language of fluid dynamics which gives equivalent results for the secular dynamics of thin rings as the the well known description using discrete elliptical streamlines formulated by Goldreich and Tremaine (1979). We use this to discuss the non linear mode interactions that appear through the excitation of higher $m$ modes due to the coupling of the $m=1$ mode with an external satellite potential, showing that they can lead to the excitation of the $m=1$ mode through a feedback process.Two conditions for the maintainance of a steady $m=1$ mode are obtained. One,being the condition for the normal mode pattern to precess uniformly requires a balance between the differential precession induced by the oblateness of the central planet,self-gravity and collisional effects and is the continuum form of that obtained from the $N$ streamline model of Goldreich and Tremaine (1979).The other condition is for the steady maintenance of the non-zero radial action of the ring on account of the normal mode.This requires a balance between input due to eccentric resonances due to external satellites and additional collisional damping associated with the presence of the $m=1$ mode We estimate that such a balance can occur in the $ε-$ring of Uranus,given its currently observed physical and orbital parameters.

description: The permanent of unitary matrices and their blocks has attracted increasing attention in quantum physics and quantum computation because of connections with the Hong-Ou-Mandel effect and the Boson Sampling problem. In that context, it would be useful to know the distribution of the permanent or other immanants for random matrices, but that seems a difficult problem.We advance this program by calculating the average of the squared modulus of a generic immanant for blocks from random matrices in the unitary group, in the orthogonal group and in the circular orthogonal ensemble. In the case of the permanent in the unitary group, we also compute the variance. Our approach is based on Weingarten functions and factorizations of permutations. In the course of our calculations we are led to a conjecture relating dimensions of irreducible representations of the orthogonal group to the value of zonal polynomials at the identity.

description: Research background: In Kenya, maize production has been severely constrained by parasitic pests and weeds such as Striga, stem borer, and fall armyworm. The government of Kenya and its partners have developed, disseminated, and promoted the continual uptake of integrated pest management technologies such as Push-Pull technology (PPT) as a way of addressing these constraints. Understanding the effect of these technologies on smallholder livelihoods is crucial, however, it is largely ignored in the literature. Purpose of the article: This study evaluates the effect of continual uptake of PPT as an integrated pest management technology on livelihood outcomes of small-scale maize producers in Homa Bay County. Methods: A multi-stage sampling procedure was used to select a sample of 240 respondents. Cross-sectional data were gathered through face-to-face interviews using a pretested semi-structured questionnaire, and analysed using descriptive statistics and propensity score matching models. Findings & Value added: Findings were that age, education level, total land owned, perception on Striga weed, stem borer, and fall armyworm severity, and land tenure positively influenced continual uptake of PPT, whereas the distance to nearest administrative centre was negatively associated with it. Propensity score matching results revealed that continual uptake of PPT had a positive and significant effect on household consumption expenditure and household dietary diversity, with a negative impact on poverty. The study, therefore, recommended policies that will ensure efficiency, literacy development, extension training, and resource availability among PPT non-adopters and dis-adopters to the level of the PPT continuous users.

Palatini quadratic gravity: spontaneous breaking of gauged scale symmetry and inflation

description: We study quadratic gravity $R^2+R_{[μν]}^2$ in the Palatini formalism where the connection and the metric are independent. This action has a {\it gauged} scale symmetry (also known as Weyl gauge symmetry) of Weyl gauge field $v_μ= (\tildeΓ_μ-Γ_μ)/2$, with $\tildeΓ_μ$ ($Γ_μ$) the trace of the Palatini (Levi-Civita) connection, respectively. The underlying geometry is non-metric due to the $R_{[μν]}^2$ term acting as a gauge kinetic term for $v_μ$. We show that this theory has an elegant spontaneous breaking of gauged scale symmetry and mass generation in the absence of matter, where the necessary scalar field ($ϕ$) is not added ad-hoc to this purpose but is "extracted" from the $R^2$ term. The gauge field becomes massive by absorbing the derivative term $\partial_μ\lnϕ$ of the Stueckelberg field ("dilaton"). In the broken phase one finds the Einstein-Proca action of $v_μ$ of mass proportional to the Planck scale $M\sim \langleϕ\rangle$, and a positive cosmological constant. Below this scale $v_μ$ decouples, the connection becomes Levi-Civita and metricity and Einstein gravity are recovered. These results remain valid in the presence of non-minimally coupled scalar field (Higgs-like) with Palatini connection and the potential is computed. In this case the theory gives successful inflation and a specific prediction for the tensor-to-scalar ratio $0.007\leq r \leq 0.01$ for current spectral index $n_s$ (at $95\%$CL) and N=60 efolds. This value of $r$ is mildly larger than in inflation in Weyl quadratic gravity of similar symmetry, due to different non-metricity. This establishes a connection between non-metricity and inflation predictions and enables us to test such theories by future CMB experiments.

description: Research background: Cocoa remains the Nigeria’s highest foreign exchange earner among all agricultural commodities, Contributed 12.5-14% of the national GDP. Currently, Nigeria is the fourth largest cocoa producing country in the world, produced approximately 328,652 tons annually. Occupational risk is a major factor reducing productivity of farm workers as it impairs physical capacity and increase vulnerability to ill health, diseases and injuries. Risk of agrochemical exposure has been attributed to work demand and unhealthy work environment. Purpose of the article: This study aimed to estimate life quality for agrochemical exposure risks of cocoa farm workers in Ondo state Nigeria. The study specifically estimates the amount an individual willingness to pay by respondents for occupational risk reduction. Methods: Multistage sampling technique that guaranteed cocoa farmers who could provide desired information on the basis of the objectives of the study was adopted for the study. Random selection of 180 cocoa farm workers from the study area. Descriptive statistics (frequency, mean and percentage) and Discrete Choice Experiment (DCE) approach that dovetailed into choice modelling and conditional logistic regression were the analytical tools used. Findings & Value added: the result revealed that 74% of the cocoa farm workers are on active age and mainly male with the mean age of 46 years. Most of the workers are illiterate that cannot read instructions on the agrochemical container. Average workers are willing to pay 830 Nigerian naira for personal protective equipment, 92 Nigerian naira for 15% wage discount as financial benefit of workplace injuries and 1024 Nigerian naira for training of workers in pesticide usage. The study concluded that better health conditions and appropriate use of personal protective equipment minimize the occupational risk. It was therefore recommended that educational programmes that will enhance farmer’s knowledge, skills and attitude to use safe methods (appropriate use of protective equipment) in pesticide usage should be adequately planned. Appropriate use of personal protective equipment to reduce exposure to agrochemicals and the risks involved in the misuse and abuse of agrochemicals should be adopted.

description: Threshold models are widely used in macroeconomics and financial analysis for their simple and obvious economic implications. With these models, however, estimation and inference is complicated by the existence of nuisance parameters. To combat this issue, Hansen (1999, Journal of Econometrics 93: 345–368) proposed the fixed-effect panel threshold model. In this article, I introduce a new command (xthreg) for implementing this model. I also use Monte Carlo simulations to show that, although the size distortion of the threshold-effect test is small, the coverage rate of the confidence interval estimator is unsatisfactory. I include an example on financial constraints (originally from Hansen [1999, Journal of Econometrics 93: 345–368]) to further demonstrate the use of xthreg.
EVALUATION OF A SHORT-TERM RESIDENTIAL PROGRAM FOR DELINQUENT ADOLESCENT MALES
Creators: name: Rachlin, Deborah Lynn
Publisher: name: American University
Year: 2023

description: A short-term residential program for delinquent adolescent males, Muncaster Mill, was evaluated to determine its effectiveness in meeting its stated objectives. The present study followed a systematic procedure for determining whether stated program objectives were being attained and based its measured variables on established theories which focus on the connection between lack of interpersonal skills and juvenile delinquency. A majority of the Muncaster Mill objectives addressed attainment of peer relationships, a major developmental task of adolescence. These program objectives were classified into five categories of interpersonal skills assumed to approximate the desired changes: responsibility, altruism, sense of belonging, socialization, and self-disclosure. Five paper and pencil instruments--The Responsibility Scale of the California Psychological Inventory, The Altruism Scale, The Adolescent Alienation Scale, The Socialization Scale of the California Psychological Inventory, and the Self-Disclosure Inventory for Adolescents--were used to measure improvement in interpersonal skills. These were administered once during the first week of residence and again during the week prior to discharge to each subject. The differences in all residents' scores were analyzed to determine if the mean improvements were significant in each of the five aspects of interpersonal skills, and whether a significant number of residents improved. Based on the residents' responses to the five instruments, the results failed to demonstrate a significant difference in either the mean level or number of residents exhibiting improvement in any of the five target areas except socialization. Although the mean difference for this variable was non-significant, the number of young men with improved socialization scores was significant. Because of the several non-treatment factors which might have influenced the study, it is difficult to state with confidence whether or not the Muncaster Mill program is effective in meeting its stated goals. However, this study provides data as well as suggestions for a systematic method by which much needed program evaluations can be accomplished in the future.

description: Atomic vapors can be prepared and manipulated at very low densities and temperatures. When they are rotating, they can reach a quantum Hall regime in which there should be manifestations of the fractional quantum Hall effect. We discuss the appearance of the principal sequence of fractions nu =p/(p+- 1) for bosonic atoms. The termination point of this series is the paired Moore-Read Pfaffian state. Exotic states fill the gap between the paired state and the vortex lattice expected at high filling of the lowest Landau level. In fermionic vapors, the p-wave scattering typical of ultralow energy collisions leads to the hard-core model when restricted to the lowest Landau level.

Event dependence may be considered as contributing to the intervention effect, or it may be considered as a source of nuisance, depending on the analysts’ specific research questions. If it is seen as a nuisance, the analysis can stratify the recurrent event times according to event order. If it is seen as contributing to the intervention effect, stratification should not be used. Models with and without stratification for event order estimate two types of treatment effects. They are analogous to per-protocol analysis and intention-to-treat analysis, respectively. In the context of chronic disease treatment, we want to estimate whether there is a cured fraction; for infectious disease prevention, this is called a nonsusceptible fraction. In infectious disease prevention, we want to understand whether an intervention protects each of its recipients to some extent (“leaky” model) or whether it totally protects some recipients but offers no protection to the rest (“all-or-none” model). The truth may be a mixture of the two modes of protection. We describe a class of regression models that can handle all three issues in the analysis of recurrent event times. The model parameters are estimated by the expectation-maximization algorithm, and their variances are estimated by Louis’s formula. We provide a new command, strmcure, for implementing these models.

description: A short-term residential program for delinquent adolescent males, Muncaster Mill, was evaluated to determine its effectiveness in meeting its stated objectives. The present study followed a systematic procedure for determining whether stated program objectives were being attained and based its measured variables on established theories which focus on the connection between lack of interpersonal skills and juvenile delinquency. A majority of the Muncaster Mill objectives addressed attainment of peer relationships, a major developmental task of adolescence. These program objectives were classified into five categories of interpersonal skills assumed to approximate the desired changes: responsibility, altruism, sense of belonging, socialization, and self-disclosure. Five paper and pencil instruments--The Responsibility Scale of the California Psychological Inventory, The Altruism Scale, The Adolescent Alienation Scale, The Socialization Scale of the California Psychological Inventory, and the Self-Disclosure Inventory for Adolescents--were used to measure improvement in interpersonal skills. These were administered once during the first week of residence and again during the week prior to discharge to each subject. The differences in all residents' scores were analyzed to determine if the mean improvements were significant in each of the five aspects of interpersonal skills, and whether a significant number of residents improved. Based on the residents' responses to the five instruments, the results failed to demonstrate a significant difference in either the mean level or number of residents exhibiting improvement in any of the five target areas except socialization. Although the mean difference for this variable was non-significant, the number of young men with improved socialization scores was significant. Because of the several non-treatment factors which might have influenced the study, it is difficult to state with confidence whether or not the Muncaster Mill program is effective in meeting its stated goals. However, this study provides data as well as suggestions for a systematic method by which much needed program evaluations can be accomplished in the future.

3D simulations of Einstein's equations: symmetric hyperbolicity, live gauges and dynamic control of the constraints

description: We present three-dimensional simulations of Einstein equations implementing a symmetric hyperbolic system of equations with dynamical lapse. The numerical implementation makes use of techniques that guarantee linear numerical stability for the associated initial-boundary value problem. The code is first tested with a gauge wave solution, where rather larger amplitudes and for significantly longer times are obtained with respect to other state of the art implementations. Additionally, by minimizing a suitably defined energy for the constraints in terms of free constraint-functions in the formulation one can dynamically single out preferred values of these functions for the problem at hand. We apply the technique to fully three-dimensional simulations of a stationary black hole spacetime with excision of the singularity, considerably extending the lifetime of the simulations.

description: Research background: There is higher level of mistrust between vegetable farmers and intermediaries in vegetable market transaction in Eastern Ethiopia. This mistrust adversely affected farmers’ livelihood which largely depended on the agriculture sector. Hence understanding factors that affect trust of farmers for intermediaries is essential. Purpose of the article: The purpose of this study is to analyse the factors determining vegetable farmers trust for intermediaries using cross sectional data collected from vegetable farmers in Eastern Ethiopia. Methods: Multistage sampling was used to select 385 households for the study. The collected data were analysed using partial least square path modelling procedure. Findings and value added: The empirical results indicated that relational investment, collaborative communication, and flexibility positively influenced trust. Moreover, collaborative communication and flexibility also positively influenced relational satisfaction. However, relational investment negatively affected opportunism. Recommendation: Intermediaries should use effective communication to improve farmers trust and relational satisfaction. They should also engage in relational investment by giving assistance and advice as this could contribute to enhancement of trust and reduction of opportunism. Intermediaries need to also attract farmers by offering satisfactory price and demonstrating flexibility where it is necessary.

description: This study was conducted to determine any relationship which may exist between Nigerian students' values and educational goals in science and non-science majors within the Consortium of Universities of Washington, D.C. Metropolitan area. Methodology. Nigerian Students' Values and Educational Goals Survey was administered to 485 Nigerian undergraduates in six institutions within the Consortium during the fall semester of 1982. A parallel survey was conducted among seventy randomly selected American undergraduate students at The American University, Washington, D.C. Sample populations for both groups consisted of all four classes of undergraduate students. The Nigerian student sample consisted of 166 Science and Non-Science majors drawn randomly from all survey respondents in the six institutions within the Consortium. The American students' sample consisted of fifty-six students out of seventy randomly selected domestic students. Survey responses were coded and analyzed through the application of percentage, frequency distribution, rank-order, Spearman rank correlation coefficient, and Chi Square test. All hypotheses were tested at 0.01 level of significance. Findings and Conclusions. All Nigerian students responding endorsed (1) being Ambitious, Honest and Intellectual as their principal instrumental values, (2) Vocational Training, Basic General Education, and Knowledge in Community Problems as the principal educational goals, and (3) Economic Security, Career, and Personal Identity as their principal life satisfactions. There was no sufficient evidence to conclude that Nigerian Science and Non-Science majors differed significantly on values, educational goals and life satisfactions. A considerable agreement was found for both groups in all three categories (values, educational goals and life satisfactions). Significant differences existed between Nigerian Freshmen and Seniors on instrumental values, educational goals and life satisfactions. Freshmen were more concerned than Seniors with Cleanliness, Honesty, Obedience, Politeness, Knowledge in Community Problems, Religion and Home Improvement. They were less concerned than Seniors with being Broadminded, Imaginative and Intellectual. They assigned lesser priorities than Seniors to Basic General Education and Art/Intellectual activities. The investigator postulated that these differences might have occurred because of some aspects of college life. American students like their Nigerian counterparts valued Economic Security, Career, and Personal Identity as their primary sources of life satisfactions. However, Career and Family were more popular among Domestic students.
Solar wind induced magnetic field around the unmagnetized Earth

description: The Earth is a planet with a dipolar magnetic field which is agitated by a magnetized plasma wind streaming from the Sun. The magnetic field shields the Earth's surface from penetrating high energy solar wind particles, as well as interstellar cosmic rays. The magnetic dipole has reversed sign some hundreds of times over the last 400 million years. These polarity reversals correspond to drastic breakdowns of the dynamo action. The question arises what the consequences for the Earth's atmosphere, climate, and, in particular, biosphere are. It is shown by kinematic estimates and three-dimensional plasma-neutral gas simulations that the solar wind can induce very fast a magnetic field in the previously completely unmagnetized Earth's ionosphere that is strong enough to protect Earth from cosmic radiations comparable to the case of an intact magnetic dynamo.
