description: Because of the semi-volatile nature of diisocyanates (being airborne in both physical vapor and particulate phases), their high reactivity and low occupational exposure limits, diisocyanate exposure evaluation has been challenging for industrial hygienists and laboratories. The objective of this study was to compare the toluene diisocyanate (2,4 and 2,6 isomers, TDI) concentration measured by five methods in a flexible polyurethane foam factory using different collection or derivatization approaches. The methods used were: OSHA 42 modified (filter, 1-(2-pyridyl)piperazine) (OSHA), Asset EZ4-NCO (denuder and filter, dibutylamine) (Asset), Iso-Chek (double-filter, 9-(N-methylaminomethyl) anthracene and 1,2-methoxyphenylpiperazine), DAN (filter, 1,8-diaminonaphthalene), and CIP10 (centrifugation, 1,2-methoxyphenylpiperazine). Particle real-time monitoring for concentration and size distribution was performed in parallel to improve the understanding of the potential bias between methods. The comparison study was performed over 3 days, providing 18 replicates for each of the 5 methods. Isocyanate concentrations collected for each sampling method were compared using linear mixed effect modeling. Compared to OSHA, which yielded the highest concentrations overall, the Asset and DAN methods provided the smallest biases (−29% (95% CI [−52;−6]) and −45% (95% CI [−67;−23]), respectively), while the CIP10 and Iso-Chek methods provided the largest biases (−82% (95% CI [−105;−66]) and −96% (95% CI [−118;−75]), respectively). The substantial bias of Iso-Chek and CIP10 seemed to be explained by the predominance of TDI in the form of sub-micron particles that were inadequately captured by these two methods due to their sampling principle, which are particle filtration without derivatizing agent and centrifugation respectively. Asset and DAN performance seemed to decrease as the sampling time increased. While DAN’s bias could be related to a reagent deficiency on the filter, the disparities between OSHA and Asset, both considered as reference methods, highlight the fact that the mechanisms of collection, derivation and extraction do not seem to be completely controlled. Finally, an upward trend has been observed between concentrations of particles below 300 nm in size and concentration levels of TDI. It has also been observed that TDI levels increased with the TDI foam index produced at the facility.

description: Point polarizable molecules at fixed spatial positions have solvable electrostatic properties in classical approximation, the most familiar being the Clausius-Mossotti (CM) formula. This paper generalizes the model and imagines various applications to nanosystems. The behavior is worked out for a sequence of octahedral fragments of simple cubic crystals, and the crossover to the bulk CM law is found. Some relations to fixed moment systems are discussed and exploited. The one-dimensional dipole stack is introduced as an important model system. The energy of interaction of parallel stacks is worked out, and clarifies the diverse behavior found in different crystal structures. It also suggests patterns of self-organization which polar molecules in solution might adopt. A sum rule on the stack interaction is found and tested. Stability of polarized states under thermal fluctuations is discussed, using the one-dimensional domain wall as an example. Possible structures for polar hard ellipsoids are considered. An idea is formulated for enhancing polarity of nanosystems by intentionally adding metallic coatings.

description: Production costs of beef vary because of seasonal changes in the weather and a seasonal variation in prices, which because of its counter-cyclic effect, could have a stabilising effect on supply. The analysis shows that the permit/quota scheme increases the price at the main city abattoirs and it depresses the price farmers receive on country auctions. If permits/quotas reduce production by as little as 5 %, then the value of the permit/quota is estimated at R52 per animal. Large feeders who are allocated quotas receive a windfall gain, but the small farmer who does not receive a quota because he is an irrigular supplier is harmed. The effect of quotas is to restrict beef production artificially. This is- in direct contrast to the effect of research on output, that is, to promote productivity. Because the pressure to sell cattle is greater during droughts, the quota value increases then. Quotas then aggravate the farmers' position during adverse times by limiting the offtake. After good rains quotas may have no value or a negative value as feeders sell cattle just to maintain their quotas.

description: One of the most challenging fauna to study in situ is the obligate cave fauna because of the difficulty of sampling. Cave-limited species display patchy and restricted distributions, but it is often unclear whether the observed distribution is a sampling artifact or a true restriction in range. Further, the drivers of the distribution could be local environmental conditions, such as cave humidity, or they could be associated with surface features that are surrogates for cave conditions. If surface features can be used to predict the distribution of important cave taxa, then conservation management is more easily obtained. We examined the hypothesis that the presence of major faunal groups of cave obligate species could be predicted based on features of the earth surface. Georeferenced records of cave obligate amphipods, crayfish, fish, isopods, beetles, millipedes, pseudoscorpions, spiders, and springtails within the area of Appalachian Landscape Conservation Cooperative in the eastern United States (Illinois to Virginia and New York to Alabama) were assigned to 20 x 20 km grid cells. Habitat suitability for these faunal groups was modeled using logistic regression with twenty predictor variables within each grid cell, such as percent karst, soil features, temperature, precipitation, and elevation. Models successfully predicted the presence of a group greater than 65% of the time (mean = 88%) for the presence of single grid cell endemics, and for all faunal groups except pseudoscorpions. The most common predictor variables were latitude, percent karst, and the standard deviation of the Topographic Position Index (TPI), a measure of landscape rugosity within each grid cell. The overall success of these models points to a number of important connections between the surface and cave environments, and some of these, especially soil features and topographic variability, suggest new research directions. These models should prove to be useful tools in predicting the presence of species in understudied areas.

description: The wholesale demand elasticity of bananas was estimated at between -0,52 and -0,66 for the short run and between -0,65 and -0,71 for the long run. Estimates of demand elasticities using Time Varying Parameters varied between -0,62 and -0,93, also indicating that the demand becomes less price elastic during summer months. Retail elasticities were estimated at between -1,42 and -1,52 for the short run and at -1,79 for the long run. The social cost of the banana control programme is estimated at between 7,8 % and 12,68 % of income transfer between producers and consumers in marketing areas. The impact of cut-backs in banana production where entry is free (any farmer can produce bananas) is to increase prices in marketing areas, but depress prices in production areas. It is uncertain whether farm income can be increased significantly through such a scheme even though the demand is inelastic, if the supply of good banana land is not limited.

description: We present analytic results for a special dimer model on the {\em non-bipartite} and {\em non-planar} checkerboard lattice that does not allow for parallel dimers surrounding diagonal links. We {\em exactly} calculate the number of closed packed dimer coverings on finite checkerboard lattices under periodic boundary conditions, and determine all dimer-dimer correlations. The latter are found to vanish beyond a certain distance. We find that this solvable model, despite being non-planar, is in close kinship with well-known paradigm-setting planar counterparts that allow exact mappings to $\mathbb{Z}_2$ lattice gauge theory.

Q-dependence of the inelastic neutron scattering cross section for molecular spin clusters with high molecular symmetry

Year: 2003
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: For powder samples of polynuclear metal complexes the dependence of the inelastic neutron scattering intensity on the momentum transfer Q is known to be described by a combination of so called interference terms. They reflect the interplay between the geometrical structure of the compound and the spatial properties of the wave functions involved in the transition. In this work, it is shown that the Q-dependence is strongly interrelated with the molecular symmetry of molecular nanomagnets, and, if the molecular symmetry is high enough, is actually completely determined by it. A general formalism connecting spatial symmetry and interference terms is developed. The arguments are detailed for cyclic spin clusters, as experimentally realized by e.g. the octanuclear molecular wheel Cr8, and the star like tetranuclear cluster Fe4.

description: We investigate thermal fluctuations in a smectic A phase of an amphiphile-solvent mixture with molecular dynamics simulations. We use an idealized model system, where solvent particles are represented by simple beads, and amphiphiles by bead-and-spring tetramers. At a solvent bead fraction of 20 % and sufficiently low temperature, the amphiphiles self-assemble into a highly oriented lamellar phase. Our study aims at comparing the structure of this phase with the predictions of the elastic theory of thermally fluctuating fluid membrane stacks [Lei et al., J. Phys. II 5, 1155 (1995)]. We suggest a method which permits to calculate the bending rigidity and compressibility modulus of the lamellar stack from the simulation data. The simulation results are in reasonable agreement with the theory.

description: Land rents can be used to monitor anticipated changes in farm profitability of a long-run nature. Rents also provide information on the relative profitability of various enterprises (opportunity cost principle) i.e. maize versus livestock. During 1983/84 rents on grazing land in the Maize Triangle averaged at R6,85 per ha, maize land R31,28 while wheat land in the Eastern Free State rented at R24,14. Data show that the expected profitability of maize was substantially higher than livestock during the period studied. Using the concepts of economic rent and transfer earnings, data indicate that the comparative advantage of maize versus livestock production in the three principal maize producing areas is the same. As rents are determined by market forces they could provide insight into the dynamic and anticipated changes in farming profitability

description: We created 4 sequences of chess moves intended (and verified) as sufficiently good (2 sequences), in play quality, or bad (2 sequences) to induce contrast. In experiment 1, 24 experienced chess-players (USCF Elo > 1300) watched these sequences and rated them with regards to overall quality (-100 to +100) and estimated Elo ratings, a proxy for play quality, of the players involved. In experiment 2, a different group of 24 experienced chess-players rated the sequences of chess games by “How much better did the winner play than the loser?” on a 1 to 7 scale. Results revealed negative contrast (experiment 1) and no evidence of condensation (experiments 1 and 2) as well as the potential that one’s own actual Elo may have anchored the ratings given to one set of stimuli.

description: The average price elasticity of demand for fresh milk is estimated from time series data at -0,78 at retail level and -0,51 at farm level. Demand functions indicate that the elasticity of fresh milk demand increased over time to near unity at retail level, due to growing proportion of Black consumers and increasing prevalence of substitutes. Elasticity estimates of industrial milk varied from -0,47 at the farm level to -0,93 at retail level. Elasticities of industrial milk was also found to increase over time. Income elasticities for fresh and industrial milk using cross sectional data were +0,44 for fresh milk and +0,40 for industrial milk. Estimates agree with the Slutsky-Schultz and Hicks Allen relation (Wold and Jureen) stating that as a rule income elasticities of necessity are smaller than price elasticities. The increase in the price elasticity of milk implies that consumption has become slightly more price responsive and that price may become a more important feature in the selling of milk. The supply elasticity of industrial milk was estimated at +0,55 at farming level.

Production Economics

description: The per capita consumption of fresh milk has been declining steadily because of increasing substitution. The price discrimination scheme employed in the fresh milk industry is analysed using a demand and supply model. Prices are shown to have set well above the free market price, inducing an estimated cutback in consumption of 8 to 10 per cent and an increase in production of 2 to 4,5 per cent, resulting in an average surplus of 13,5 per cent of fresh milk sales. The transfer from consumers to producers is estimated at between 12,7 and 17,1 per cent of the value of fresh milk production. Approximately half of this transfer is absorbed by the Dairy Board as levies and occurs at a social cost. Price discrimination may be to the detriment of producers in the long term as artificially high prices may encourage the possible irreversible consumption of substitutes.

description: Having disk-to-star accretion rates on the order of 10$^{-4}\,M_{\odot}$/yr, FU Orionis-type stars (FUors) are thought to be the visible examples for episodic accretion. FUors are often surrounded by massive envelopes, which replenish the disk material and enable the disk to produce accretion outbursts. We observed the FUor-type star V346 Nor with ALMA at 1.3~mm continuum and in different CO rotational lines. We mapped the density and velocity structure of its envelope and analyzed the results using channel maps, position-velocity diagrams, and spectro-astrometric methods. We discovered a pseudo-disk and a Keplerian disk around a 0.1 $M_{\odot}$ central star. We determined an infall rate from the envelope onto the disk of 6$\times$10$^{-6}\,M_{\odot}$/yr, a factor of few higher than the quiescent accretion rate from the disk onto the star. This hints for a mismatch between the infall and accretion rates as the cause of the eruption.

description: A numerical approach to compute tensor integrals in one-loop calculations is presented. The algorithm is based on a recursion relation which allows to express high rank tensor integrals as a function of lower rank ones. At each level of iteration only inverse square roots of Gram determinants appear. For the phase-space regions where Gram determinants are so small that numerical problems are expected, we give general prescriptions on how to construct reliable approximations to the exact result without performing Taylor expansions. Working in 4+epsilon dimensions does not require an analytic separation of ultraviolet and infrared/collinear divergences, and, apart from trivial integrals that we compute explicitly, no additional ones besides the standard set of scalar one-loop integrals are needed.

title: Beyond the Naughty Step: The intersections of class and gender in contemporary parenting culture
Creators: name: Jensen, Tracey
Publisher: name: The Open University
Year: 2010

description: This thesis examines the texture of contemporary parenting culture, examining how 'childrearing', as the activity of raising children, has been rhetorically eclipsed by 'parenting', as a broader orientation towards one's children, oneself and the future. Parenting has been increasingly visualised across culture and policy as both a classless activity and as the key to transcending social inequalities of all kinds. In these visualisations, it is poor parenting which limits and constrains children. Consequently, good, competent or responsible parenting has become imbued cross a range of sites with enormous explanatory power, and is invoked to account for developmental differences in behaviour, vocabulary, and cognition. This thesis critically examines these socio-cultural shifts and explores how parenting discourse is implicated within these drifts away from a sociological imagining of inequality and towards a more psychological account of social change. It pays specific attention to one television programme, Supernanny (Richochet Productions, 2003-), which proved highly popular amongst viewers and highly tenacious in policy circles; a programme in which the staging of 'poor parenting' became an opportunity for Both education and entertainment. This thesis pays close attention to the subjectivising encounters between parenting culture and parents. It argues that, far from parenting being a classless activity, it has emerged as a new site for the production of social distinction.

description: News diversity in the media has for a long time been a foundational and uncontested basis for ensuring that the communicative needs of individuals and society at large are met. Today, people increasingly rely on online content and recommender systems to consume information challenging the traditional concept of news diversity. In addition, the very concept of diversity, which differs between disciplines, will need to be re-evaluated requiring an interdisciplinary investigation, which requires a new level of mutual cooperation between computer scientists, social scientists, and legal scholars. Based on the outcome of a interdisciplinary workshop, we have the following recommendations, directed at researchers, funders, legislators, regulators, and the media industry:  
- Conduct interdisciplinary research on news recommenders and diversity. 
- Create a safe harbor for academic research with industry data. 
- Strengthen the role of public values in news recommenders. 
- Create a meaningful governance framework for news recommenders. 
- Fund a joint lab to spearhead the needed interdisciplinary research, boost practical innovation, develop reference solutions, and transfer insights into practice.

description: Simultaneous diagonal flips in plane triangulations are investigated. It is proved that every $n$-vertex triangulation with at least six vertices has a simultaneous flip into a 4-connected triangulation, and that it can be computed in O(n) time. It follows that every triangulation has a simultaneous flip into a Hamiltonian triangulation. This result is used to prove that for any two $n$-vertex triangulations, there exists a sequence of $O(\log n)$ simultaneous flips to transform one into the other. The total number of edges flipped in this sequence is O(n). The maximum size of a simultaneous flip is then studied. It is proved that every triangulation has a simultaneous flip of at least ${1/3}(n-2)$ edges. On the other hand, every simultaneous flip has at most $n-2$ edges, and there exist triangulations with a maximum simultaneous flip of ${6/7}(n-2)$ edges.

Mythologizing Mary: William Allan’s The Murder of David Riccio and Scottish National Identity in the 1820s
Creators: name: Grega, Danielle Therese
Publisher: name: American University

description: This thesis analyzes Sir William Allan’s history painting The Murder of David Riccio (1833) in relation to the formation of Scottish identity at a pivotal moment in the nation’s history. The painting represents the death in 1566 of Mary Stuart’s trusted secretary at the hands of her husband Henry Stuart, Lord Darnley, while the pregnant queen watches the grisly killing unfold. I argue that Allan uses the historical figure of Mary Stuart, Queen of Scots, as an allegory of Scotland. At the time Allan painted this work, artists across Europe were grappling with the problem of how pictorially to define “the nation”; often, they used female figures as allegorical representations of that abstract concept. Placing Allan’s painting in its historical and political context, I relate it to the artist’s Unionist political beliefs. In my interpretation, the painting attempts to forge a distinctly Scottish identity by celebrating one of the nation’s foremost leaders, while also legitimizing its union with Great Britain. I show that gender ideology plays a key role in this complex balancing act. By representing Mary as a passive and compliant figure, Allan makes Scotland the feminized partner to its more “masculine,” powerful partner, Britain. Allan thus mobilizes Mary as a symbolic figure who reconciles the nation’s particular character and autonomous past with its identity as a part of the United Kingdom.

description: A short overview of theoretical models for the description of the relaxation processes in metals excited by a short laser pulse is presented. The main effort is given to description of different processes which are taking place after absorption of the laser pulse. Widely used two temperature model is discussed and the conditions of applicability of this model are identified. Various approaches for solving the Boltzmann kinetic equations are discussed. It is identified that in the case of low excitation limit the relaxation is determined by the emission of phonons by photoexcited electrons. The possibility to obtain the value of the electron phonon coupling constant from experiments is discussed.

description: We have studied the nucleation of superconductivity in a mesoscopic Al loop, enclosing magnetic dot with perpendicular magnetization. The superconducting phase boundary Tc(B), determined from transport measurements, is asymmetric with respect to the polarity of an applied magnetic field. The maximum critical temperature has been found for a finite applied magnetic field, which is antiparallel to the magnetization of the dot. Theoretical phase boundary shows a good agreement with the experimental data.

description: A tanulmány célja feltárni, hogy mely tényezők és milyen mértékben befolyásolják a pedagógusok érzelmi elkötelezettségét. Munkánkhoz egy 2015-ben a Debreceni Egyetem Gyermeknevelési és Felnőttképzési Karán végzett empirikus felmérés (IMV adatbázis, N = 824) részeredményeit használtuk fel. Kutatási eredményeink arra utalnak, hogy a pedagógusok iskolai végzettségének szintje és pályán eltöltött idejük mértéke összefügg érzelmi elkötelezettségükkel. Az utóbbi ugyancsak kapcsolatba hozható az intézmény gyermeklétszámának nagyságával és az oda járó halmozottan hátrányos helyzetű gyerekek/ diákok arányával. A pedagógusok érzelmi elkötelezettségét befolyásolja továbbá vezetőjük tevékenységének megítélése és az intézmény vezetését, működését meghatározó külső tényezők is. A tanulmány közreadásával segítséget kívánunk nyújtani a döntéshozóknak, a munkáltatóknak és az intézményvezetőknek azon tényezők felismeréséhez, amelyek javításával hozzájárulhatnak a pedagógusok érzelmi elkötelezettségének kialakításához és hosszú távú fenntartásához. ------------- The purpose of the study is to disclose which factors have influence on the pedagogues affective commitment and how much. The source of the data is one part of our empirical survey (IMV database, N = 827) made at Faculty of Child and Adult Education of the University of Debrecen. Results of the research refer to connection between the pedagogues’s education level, career spans and the affective commitment. The last one related to the number of children at the institute and the number of students with multiple disatvantages. Pedagogues’ affective commitment is tampered with their consideration of the leader’s activity and the external factors which influence operation and management of the institution. To publishing this study we would like to assist the decision-makers, the employers and the heads of institutions to identify factors whereby improvements could contribute the development and long-term maintenance of pedagogues’ affective commitment.
Stability and correlations in dilute two-dimensional boson systems

description: The hyperspherical adiabatic expansion method is used to describe correlations in a symmetric boson system rigorously confined to two spatial dimensions. The hyperangular eigenvalue equation turns out to be almost independent of the hyperradius, whereas the solutions are strongly varying with the strength of the attractive two-body potentials. Instability is encountered in hyperangular, hyperradial, and mean-field equations for almost identical strengths inversely proportional to the particle number. The derived conditions for stability are similar to mean-field conditions and closely related to the possible occurrence of the Thomas and Efimov effects. Renormalization in mean-field calculations for two spatial dimensions is probably not needed.

description: This study provides an overview of science from the Wikipedia perspective. A methodology has been established for the analysis of how Wikipedia editors regard science through their references to scientific papers. The method of co-citation has been adapted to this context in order to generate Pathfinder networks (PFNET) that highlight the most relevant scientific journals and categories, and their interactions in order to find out how scientific literature is consumed through this open encyclopaedia. In addition to this, their obsolescence has been studied through Price index. A total of 1 433 457 references available at Altmetric.com have been initially taken into account. After pre-processing and linking them to the data from Elsevier's CiteScore Metrics the sample was reduced to 847 512 references made by 193 802 Wikipedia articles to 598 746 scientific articles belonging to 14 149 journals indexed in Scopus. As highlighted results we found a significative presence of "Medicine" and "Biochemistry, Genetics and Molecular Biology" papers and that the most important journals are multidisciplinary in nature, suggesting also that high-impact factor journals were more likely to be cited. Furthermore, only 13.44% of Wikipedia citations are to Open Access journals.

description: The layered sodium cobalt oxyhydrate superconductor Na0.3CoO2*1.4H2O is shown through X-ray diffraction and thermogravimetric studies to be one of a series of hydrated phases of Na0.3CoO2. Further, it is shown that the material is exceptionally sensitive to both temperature and humidity near ambient conditions, easily dehydrating to a non-superconducting lower hydrate. The observation of this stable lower hydrate with c=13.8 angstroms implies that the superconductivity turns on in this system between CoO2 layer spacings of 6.9 and 9.9 angstroms at nominally constant chemical doping.

description: We derive an exact operator bosonization of a finite number of fermions in one space dimension. The fermions can be interacting or noninteracting and can have an arbitrary hamiltonian, as long as there is a countable basis of states in the Hilbert space. In the bosonized theory the finiteness of the number of fermions appears as an ultraviolet cut-off. We discuss implications of this for the bosonized theory. We also discuss applications of our bosonization to one-dimensional fermion systems dual to (sectors of) string theory such as LLM geometries and c=1 matrix model.
