description: We show that the metric universal cover of a plane with a puncture yields an example of a nonstandard hull properly containing the metric completion of a metric space. As mentioned by do Carmo, a nonextendible Riemannian manifold can be noncomplete, but in the broader category of metric spaces it becomes extendible. We give a short proof of a characterisation of the Heine-Borel property of the metric completion of a metric space M in terms of the absence of inapproachable finite points in *M.

Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: The Sudbury Neutrino Observatory (SNO) is capable of measuring simultaneously the flux of electron-type neutrinos and the total flux of all active flavours of neutrinos originating from the Sun. A model-independent test of neutrino flavour transformation was performed by comparing these two measurements. Assuming an undistorted neutrino energy spectrum, this transformation has been definitively demonstrated in the pure D2O phase of the SNO experiment. In the second phase with dissolved NaCl in the D2O, the total active solar neutrino flux was measured without any assumption on the energy dependence of flavour transformation. In this talk, results from these measurements, their physics implications and the current status of the SNO experiment are presented.

description: This paper evaluates household food security situation in Kenya in terms of access to food, using cross sectional data from the Kenya Integrated Household Budget Surveys (KIHBS). By estimating price and income elasticities, which provides an indication of the sensitivity of households to market shocks and thus the degree of household’s constraint to access food. The empirical approach involve estimation of demand system analysis the QUAIDS model. Existing research focuses on disaggregate food items and other developing countries, but none has specifically used the QUAIDS model for the aggregated food groups to analyse food consumption patterns nationally for the Kenyan context. The empirical results show positive expenditure elasticities while all compensated and uncompensated price elasticities show negative results. While their magnitudes vary; expenditure elasticities for meat and fish, and essential condiments are elastic (sensitive to changes) and are considered as luxuries as their elasticities are greater than one. Whereas cereal and bread, dairy products, fruit and vegetables and other condiments, have both inelastic price and expenditure elasticities; they are considered to be normal goods with values less than one. With respect to low income households, rural households and those highly dependent on the consumption of own produced food (“auto-consumption”), a reverse relationship is exhibited where meat and fish expenditure are inelastic hence perceived as normal foods, which is somewhat unexpected. However, in Kenya this finding may be attributed to the fact that a majority of the households in the survey depend on their own domesticated animals for meat and fish consumption. Hence they are not largely involved in the formal market services and prices. Further analysis shows that household size, regional differences, the ratio of food expenditure to total income and the ratio of auto-consumption are statistically significant, and hence have a great impact on food consumption expenditure. The results are broadly consistent with microeconomic theory, however exceptions indicate an unusual pattern (less sensitivity to income changes) for the rural and low income households’ meat and fish consumption. Interestingly, the low income households in our sample show that the food income elasticity for meat and fish to be less than one. These results should inform the design of policies aimed at improving the nutritional status of the poor, children and other vulnerable individuals.

description: This study compared the utilization and perceived importance of support sources by a sample of registered nurses with a sample of traditional nursing students. The purpose of this study was to determine if there were significant differences between these two groups of students. A number of differences were predicted. Subjects were 85 registered nurses and 117 traditional nursing students enrolled in a state university baccalaureate nursing program during the Spring semester of 1983. Subjects were voluntary and given anonymity. Data were collected from two instruments constructed by the researcher: the Support Source Inventory (SSI), and the Personal Data Inventory (PDI). Based upon results from the Personal Data Inventory (PDI), registered nurses were older than traditional nursing students, had more mate/spouses and more dependents, tended to be employed in the field of nursing and had a part-time university status. Traditional nursing students tended to be younger, married, employed, with few dependents and had a full-time university status. The Support Source Inventory (SSI) indicated that the two student groups demonstrated differences, as well as some similarities, in their utilization and perceived importance of support sources that assisted them to pursue their baccalaureate nursing program. Though both groups rated their own self support as highly important, traditional nursing students relied heavily on mate/spouses and student friends who were registered nurses, while registered nurses utilized support from mate/spouses, children, student friends who were registerd nurses, and the registered nurse advisor. Neither group received much support from nursing faculty, bank loans, college loans/grants, co-workers, and therapy-related support.

description: This paper considers the problem of designing PES-type contracts to encourage participation and spatial coordination amongst private forest owners in Finland. The aim of the policy is to increase efforts to mitigate risks from invasive forest pests and diseases. Such control actions yield spill-over benefits to other landowners and to wider society, meaning that the level of privately-optimal disease control is likely to be less than the socially-optimal level. The policy designer may wish to encourage spatial coordination in the uptake of such PES-type contracts, as spatial coordination delivers an increase in the effectiveness of control measures on disease risks. We conducted a choice experiment with private forest owners in Finland in October 2016. The study elicited the preferences of woodland owners with respect to the design of forest disease control contracts, and gauged their willingness to cooperate with neighbouring forest owners within the framework of such programs.

description: We investigate the localization transition for a simple model of interface which interacts with an inhomonegeous defect plane. The interface is modeled by the graph of a function $ϕ: \mathbb Z^2 \to \mathbb Z$,and the disorder is given by a fixed realization of a field of IID centered random variables$(ω_x)_{x\in \mathbb Z^2}$. The Hamiltonian of the system depends on three parameters $α,β>0$ and $h\in \mathbb R$ which determine respectively the intensity of nearest neighbor interaction the amplitude of disorder and the mean value of the interaction with the substrate, and is given by the expression $$\mathcal H(ϕ):= β\sum_{x\sim y} |ϕ(x)-ϕ(y)|- \sum_{x} (αω_x+h){\bf 1}_{\{ϕ(x)=0\}}.$$ We focus on the large-$β$/rigid phase phase of the Solid-On-Solid (SOS) model. In that regime, we provide a sharp description of the phase transition in $h$ from a localized phase to a delocalized one corresponding respectivelly to a positive and vanishing fraction of points with $ϕ(x)=0$. We prove that the critical value for $h$ corresponds to that of the annealed model and is given by $h_c(α)= -\log \mathbb E[e^{αω}]$, and that near the critical point, the free energy displays the following critical behavior $$F_β(α,h_c+u )\stackrel{u\to 0+}{\sim} \max_{n\ge 1} \left\{θ_1 e^{-4βn} u- \frac{1}{2}θ^2_1 e^{-8βn} \frac{\mathrm{Var}\left[e^{αω}\right]}{\mathbb E \left[ e^{αω} \right]^2}\right\}.$$ The positive constant $θ_1(β)>0$ is defined by the asymptotic probability of spikes for the infinite volume SOS with $0$ boundary condition $θ_1(β):=\lim_{n\to \infty} e^{4βn}\mathbf P_β (ϕ({\bf 0})=n)$ ...

A MICRO-STUDY OF THE EFFECT OF CHOICE OF TECHNOLOGY ON EMPLOYMENT AND OUTPUT: THE CASE OF SMALL TEXTILE FIRMS IN NIGERIA
Creators: name: Ekwere, Aniefiok O.
Publisher: name: American University
Year: 2023

description: The objective of this study is to analyze as well as appraise, with the aid of both qualitative and quantitative data, the actual and potential contribution of small plants to unemployment reduction and output expansion within the Nigerian context. For this purpose, a field survey of small weaving plants, with special emphasis on the study of handlooms, was carried out. An explanation of the existing contrast in productivity levels of small plants is made possible with the aid of both statistical and descriptive analysis of survey data. The study compares the relative contribution of the small and large plants to employment and output per unit of investment. The study suggests that it is possible to increase both the rate of labor absorption and output by expanding small-scale industries of the intermediate sector. In contrast, expansion of the modern capital-intensive sector often results in output increases, but also in unemployment increases. The study also analyzes in some detail the technique and processes of handloom weaving and the cost and labor content of these processes. The analysis and findings of this study provide useful information for policy makers faced with the problem of designing programs of support for the promotion of small-scale industries. As for policy, the study also proposes the establishment of a specialized financial institution, such as the Small Industry Development Bank, to cater to the credit, technical, and managerial needs of small plants.

description: For the representation of eigenstates on a Poincaré section at the boundary of a billiard different variants have been proposed. We compare these Poincaré Husimi functions, discuss their properties and based on this select one particularly suited definition. For the mean behaviour of these Poincaré Husimi functions an asymptotic expression is derived, including a uniform approximation. We establish the relation between the Poincaré Husimi functions and the Husimi function in phase space from which a direct physical interpretation follows. Using this, a quantum ergodicity theorem for the Poincaré Husimi functions in the case of ergodic systems is shown.

description: Quantifying how key life-history traits respond to climatic change is fundamental in understanding and predicting long-term population prospects. Age at first reproduction (AFR), which affects fitness and population dynamics, may be influenced by environmental stochasticity but has rarely been directly linked to climate change. Here, we use a case study from the highly seasonal and stochastic environment in High-Arctic Svalbard, with strong temporal trends in breeding conditions, to test whether rapid climate warming may induce changes in AFR in barnacle geese, Branta leucopsis. Using long-term mark–recapture and reproductive data (1991–2017), we developed a multi-event model to estimate individual AFR (i.e. when goslings are produced). The annual probability of reproducing for the first time was negatively affected by population density but only for 2 year old, the earliest age of maturity. Furthermore, advanced spring onset (SO) positively influenced the probability of reproducing and even more strongly the probability of reproducing for the first time. Thus, because climate warming has advanced SO by two weeks, this likely led to an earlier AFR by more than doubling the probability of reproducing at 2 years of age. This may, in turn, impact important life-history trade-offs and long-term population trajectories.

description: Treatment of secondary and tertiary alcohols with bromine in the presence of silver salts results in the production of substituted tetrahydrofuran derivatives through abstraction of a (delta)-hydrogen atom, and, in the case of secondary alcohols, the corresponding ketones can also be produced by abstraction of the (alpha)-hydrogen. A study of the kinetics of the reactions that occur in the absence of light during treatment of secondary and tertiary aliphatic alcohols with bromine in the presence of silver salts was conducted. Kinetically controlled experiments were conducted in the presence of silver oxide, silver carbonate and with no silver salts, with a ten-fold excess of the alcohol over the other constituents. Spectrophotometric measurements revealed that with an excess of the alcohol in the presence of either silver salt, the bromine was rapidly consumed in a first order manner to form the hypobromite from the alcohol. Rates of hypobromite decomposition were obtained by spectrophotometric measurements and by indirect iodometry. Comparison of the relative pseudo-first order rates of hypobromite decomposition determined for each alcohol in the presence of each silver salt indicated that an increase in the degree of substitution at the carbon (delta) to the hypobromite group decreased the stability of the hypobromite. This increase in decomposition rate was less pronounced when silver oxide was used than in the presence of silver carbonate. Product analysis by gas chromatography and gas chromatography-mass spectrometry indicated that the cyclic ethers, ketones and olefins were produced, with differences in the product distributions observed with each silver salt. The activity of the silver oxide in acting as a heterogeneous reactant surface was found to be much greater when prepared from silver nitrate and base just prior to use. The highly covalent nature of the silver oxide crystal accounts for the observed differences in surface activity from the other silver salts used to promote the cyclization of alcohols. The results of this study suggest that the product distributions obtained under kinetically controlled conditions may not agree with those obtained under other conditions.

description: Composite materials/structures are advancing in product efficiency, cost-effectiveness and the development of superior specific properties. There are increasing demands in their applications to load-carrying structures in aerospace, wind turbines, transportation, and medical equipment, etc. Thus robust and reliable non-destructive testing (NDT) of composites is essential to reduce safety concerns and maintenance costs. There have been various NDT methods built upon different principles for quality assurance during the whole lifecycle of a composite product. This paper reviews the most established NDT techniques for detection and evaluation of defects/damage evolution in composites. These include acoustic emission, ultrasonic testing, infrared thermography, terahertz testing, shearography, digital image correlation, as well as X-ray and neutron imaging. For each NDT technique, we cover a brief historical background, principles, standard practices, equipment and facilities used for composite research. We also compare and discuss their benefits and limitations, and further summarise their capabilities and applications to composite structures. Each NDT technique has its own potential and rarely achieves a full-scale diagnosis of structural integrity. Future development of NDT techniques for composites will be directed towards intelligent and automated inspection systems with high accuracy and efficient data processing capabilities.

description: Quantifying how key life-history traits respond to climatic change is fundamental in understanding and predicting long-term population prospects. Age at first reproduction (AFR), which affects fitness and population dynamics, may be influenced by environmental stochasticity but has rarely been directly linked to climate change. Here, we use a case study from the highly seasonal and stochastic environment in High-Arctic Svalbard, with strong temporal trends in breeding conditions, to test whether rapid climate warming may induce changes in AFR in barnacle geese, Branta leucopsis. Using long-term mark–recapture and reproductive data (1991–2017), we developed a multi-event model to estimate individual AFR (i.e. when goslings are produced). The annual probability of reproducing for the first time was negatively affected by population density but only for 2 year old, the earliest age of maturity. Furthermore, advanced spring onset (SO) positively influenced the probability of reproducing and even more strongly the probability of reproducing for the first time. Thus, because climate warming has advanced SO by two weeks, this likely led to an earlier AFR by more than doubling the probability of reproducing at 2 years of age. This may, in turn, impact important life-history trade-offs and long-term population trajectories.
EDUCATIONAL PREFERENCES OF A SAMPLE OF OLDER ADULTS LIVING IN PARTICULAR PLANNED RETIREMENT COMMUNITIES (WASHINGTON, D.C.)
Creators: name: Riggott, Jane Sheehan
Publisher: name: American University

description: The study was conducted to identify the educational preferences, as assessed by the Educational Preference Survey, of older adults living in particular planned retirement communities and to delineate profiles of older adults who expressed an interest in taking credit and/or non-credit courses and those who were not interested in taking college courses. As an explanatory descriptive study, the following research questions were postulated: (1) In terms of residence and marital status, age, sex, education, mobility, and health, in the study sample, what are the modal characteristics of older adults who are interested in taking: (a) only credit courses? (b) only non-credit courses? (c) both credit and non-credit courses? (d) no courses?; Two questionnaires were designed and distributed to 746 residents of three planned retirement communities in the Washington, D.C. area. Each community represented a generic type of community. Responses from 570 subjects (76.4 percent) were analyzed to determine the modal characteristics of the interested respondents. Profiles were drawn of those interested in credit courses only, non-credit courses only, both credit and non-credit courses, and no courses. The basic findings of the study were that adult residents of planned retirement communities have almost no interest in taking only credit courses. Health, mobility, and education level appeared to be important factors in the older adult's decision to take courses. Among the interested respondents, there was greatest interest in taking non-credit courses in business, fine arts, and the humanities. Residents of planned retirement communities expressed interest in taking courses about four times more frequently than older adults in general currently participate in courses. The respondents strongly favor their retirement community as the location of courses. Leisure residents preferred a length of three hours whereas total life-care residents preferred one hour. Both groups preferred the lecture format and would spend a maximum of $75 per course. Interest in taking courses was 43.4 percent for leisure residents, 21.4 percent for total life-care residents, and 3 percent for domiciliary residents.

 Cordylura aricioides Zetterstedt, 1855: 4765. HOLOTYPE: ♀, Sweden,‘Hab. in Scania boreali, rarissime: ad praedium Ljungby [= northern Skåne, very rare: environs of the farmstead Ljungby], inter dies 9 & 16 Jun. 1853 [= between 9. and 16. July 1853], Wallengren leg.’ (depository unknown).
 Note. ZETTERSTEDT (1855) wrote: ‘ ♀. Similis Cord. ariciae (33), [...] seta omnio nuda, nigra, basi incrassata […] Palpi parvi, retracti, nigri […] Pedes simplicipes, toti nigri’ [= ♀. Similar to Cord. aricia (33), arista bare, at base stronger […] Palpi small, retracted, black […] Legs simple, entirely black]. The species was marked in the original text as ‘ C. aricioides Zett. n. sp. ’. SCHINER (1864a: 12) quoted it as ‘ Cleigastra aricioides Zett. ’ from ‘Nordschweden’ [= northern Sweden], BECKER (1905: 1) listed as a valid species, and GORODKOV (1986: 39) regarded it as a doubtful species. The identity of the species remains entirely unclear.

description: Cut generation and lifting are key components for the performance of state-of-the-art mathematical programming solvers. This work proposes a new general cut-and-lift procedure that exploits the combinatorial structure of 0-1 problems via a binary decision diagram (BDD) encoding of their constraints. We present a general framework that can be applied to a wide range of binary optimization problems and show its applicability for second-order conic inequalities. We identify conditions for which our lifted inequalities are facet-defining and derive a new BDD-based cut generation linear program. Such a model serves as a basis for a max-flow combinatorial algorithm over the BDD that can be applied to derive valid cuts more efficiently. Our numerical results show encouraging performance when incorporated into a state-of-the-art mathematical programming solver, significantly reducing the root node gap, increasing the number of problems solved, and reducing the run-time by a factor of three on average.

description: We report on the discovery of an infrared counterpart to the X-ray transient XTE J1720-318 on 2003 January 18, nine days after an X-ray outburst, and the infrared light curve during the first 130 days after the outburst. The infrared light curve shows a decline of about 1.2 mag from the peak magnitude of Ks about 15.3 over the observation period, and a secondary maximum, about 40 days after the outburst. Another small increase in the flux was also recorded about 20 days after the outburst. These increases were also detected in the X-ray light curve. The J H Ks colors are consistent with an X-ray irradiated accretion disk suffering an extinction of Av about 8, which is also inferred from its X-ray spectrum and the extinction map constructed from far-infrared dust emission of this line of sight. These J, H, and Ks observations demonstrate that useful data can be obtained even for such an object, which suffers heavy optical extinction, possibly located beyond the Galactic center.

A statistical theory of nucleation in the presence of uncharacterised impurities

description: First order phase transitions proceed via nucleation. The rate of nucleation varies exponentially with the free-energy barrier to nucleation, and so is highly sensitive to variations in this barrier. In practice, very few systems are absolutely pure, there are typically some impurities present which are rather poorly characterised. These interact with the nucleus, causing the barrier to vary, and so must be taken into account. Here the impurity-nucleus interactions are modelled by random variables. The rate then has the same form as the partition function of Derrida's Random Energy Model, and as in this model there is a regime in which the behaviour is non-self-averaging. Non-self-averaging nucleation is nucleation with a rate that varies significantly from one realisation of the random variables to another. In experiment this corresponds to variation in the nucleation rate from one sample to another. General analytic expressions are obtained for the crossover from a self-averaging to a non-self-averaging rate of nucleation.
