description: Aszőlő rügyfakadási időpontjának modellezése és előrejelzése növényvédelmi és gazdasági szempontból nélkülözhetetlen lépés a szőlőtermelésben. Tanulmányunkat öt fehérborszőlő-fajta (Chardonnay, Rajnai rizling, Hárslevelű, Pinot blanc és Szürkebarát), valamint ezek klónfajtáinak 2000 és 2004 között felvételezett adataival végeztük. Az ültetvények a Duna borrégión belül, a Kunsági borvidékhez tartozó Helvécián találhatóak. Számításainkhoz egy olyan matematikai modellt állítottunk fel, mely kis hibával megbecsüli a várható rügyfakadás napját. Amodell az általánosan használt kumulált hőösszegszámításon alapul, az optimalizálást pedig a becsült időpontok napokban számított hibájára végeztük. Az optimális bázishőmérsékletet 6 °C-ban állapítottuk meg. Amodell becslésének hibája számításaink alapján 1 és 6 nap között mozog, átlagosan 2,04 nap. ------------------------------------------------------- Modelling and forecasting the date of the opening of grape buds is an essential operation in viticulture both for the purpose of pest control and business administration. Our paper is based on data recorded for 5 white grape varieties (Chardonnay, Rajnai rizling, Hárslevelű, Pinot blanc and Szürkebarát), as well as cloned varieties, between 2000 and 2004. The vineyards are situated in the Danube wine region, in the wine subregion of Kunság, in the community of Helvécia. The calculations were based on a mathematical model which is able to estimate the expected day of bud opening with a low margin. The model relies on the widespread method of calculating the effective accumulated temperature over the growing season and was optimised for the error of the estimated date, expressed in days. The optimum base temperature was set to 6 °C. The forecast error of the model is calculated to range from 1 to 6 days, with the mean value being 2.04 days.

description: Afiatalkorúak célcsoportja a piac leginkább befolyásolható szegmensét jelenti. Kutatásaink szerint a fiatalok fele nem fordít különösebb figyelmet az egészséges táplálkozásra, s a fiataloknak csupán egyharmada érti az élelmiszercímke jelöléseit. Súlyosbítja a helyzetet, hogy magas zsír-, só-, cukortartalmú élelmiszereket (például gyorséttermi láncok termékei, kóla, chips) népszerűsítenek. Ahazai élelmiszercímke-szabályozásban mindenképpen célszerű figyelembe venni más országok gyakorlatát, különös tekintettel az Egyesült Államok élelmiszercímkéire, valamint a Magyar Nemzeti Szívalapítvány elképzeléseire. Az elmaradás eredménye a 20%-ban túlsúlyos, egészségügyi problémákkal küzdő fiatal nemzedék! ---------------------------------------------------------------- The target audience of young people the most impressionable segment of the market. Our research shows that half of all young people hardly pay attention to healthy eating and only a third of them understand markings on food labels. The situation is aggravated by the fact that foods rich in fat, sugar and/or salt (e.g. the products of fast-food chains, coke, chips) are being popularized. There are not food labels supporting the consumer decision simply in Hungary. It is necessary to take other countries’ practice into consideration when designing the Hungarian food labeling regime, especially the food labels in the USA, as well as the concepts of the Hungarian National Heart Foundation. Not focusing on this issue results in a young generation, one fifth of which is facing obesity and health problems.

description: We have studied the low-frequency dielectric properties of the phase-separated manganite Pr0.7Ca0.3MnO3 as a function of applied magnetic field in the low temperature phase-separated state. The dielectric constant is strongly field dependent and also depends on the magnetic field history of the sample. The dielectric behavior appears to be associated with the hopping of polaronic charge carriers, and we can derive the field dependent hopping energy barrier from the frequency dependence of the dielectric constant. This analysis allows us to associate the metal-insulator transition observed in this material with the field-induced suppression of the polaron activation energy.

description: Az éghajlatváltozás hatásai a minőségi termelés követelményei, a rentábilis termelés igénye, a termeléstechnológiai elemek megújításának, korszerűsítésének szükségessége egyaránt sürgetik a fenti követelményeket szem előtt tartó, annak megfelelni akaró módszert, a szabadföldi intenzív termelést, melynek legfontosabb elemei: az időszakos talaj-, növény- és légtértakarás, a víztakarékos öntözési módok alkalmazása és a retardált műtrágya használata. Az időszakos talaj-, növény- és légtértakarással a szedési időszak meghosszabbítható, és egyúttal javítható a talaj vízgazdálkodása, valamint visszaszorítható a gyomosodás. A mikroöntözés alkalmazásával, azonos vízmennyiséggel kétszer akkora terület öntözhető. Retardált (fékezett lebomlású) műtrágyák használatával jobb növénytápláltság érhető el, és az esetek többségében a fejtrágyázás is feleslegessé válik. Célszerű létrehozni mielőbb egy kiváló nyersanyagokból kiváló minőségű, jellegzetesen magyar termékeket gyártó feldolgozóipart, amelynek kínálatában a funkcionális (pharma) termékek is megjelennek. Eközben arról sem szabad megfeledkezni, hogy jó minőségű konzerv csak jó minőségű nyersanyagból készíthető! ------------------------------------------------------------ The climate is changing, and we have to adapt to it. The possible methods of compliance include temporary soil, plant and air covering, water economical irrigation, and the ap¬plication of retardable fertilizers. Temporary soil, plant and air covering with plastic sheets is a method applied most¬ly under temperate climatic conditions. Its key purpose is to enable earlier harvest and to lengthen the picking period. The use of economical irrigation methods can double the area which can be irrigated with the same amount of water. The application of retardable fertilizers can ensure harmonious plant nutrition without top dressing. The renewal of the Hungarian canning industry is an urgent task. The development of vegetable production is unthinkable without valuable canning products.

description: The Supernova Cosmology Project has conducted the `See Change' programme, aimed at discovering and observing high-redshift (1.13 $\leq$ z $\leq$ 1.75) Type Ia supernovae (SNe Ia). We used multi-filter Hubble Space Telescope (HST) observations of massive galaxy clusters with sufficient cadence to make the observed SN Ia light curves suitable for a cosmological probe of dark energy at z > 0.5. This See Change sample of SNe Ia with multi-colour light curves will be the largest to date at these redshifts. As part of the See Change programme, we obtained ground-based spectroscopy of each discovered transient and/or its host galaxy. Here we present Very Large Telescope (VLT) spectra of See Change transient host galaxies, deriving their redshifts, and host parameters such as stellar mass and star formation rate. Of the 39 See Change transients/hosts that were observed with the VLT, we successfully determined the redshift for 26, including 15 SNe Ia at z > 0.97. We show that even in passive environments, it is possible to recover secure redshifts for the majority of SN hosts out to z = 1.5. We find that with typical exposure times of 3 - 4 hrs on an 8m-class telescope we can recover ~75% of SN Ia redshifts in the range of 0.97 < z < 1.5. Furthermore, we show that the combination of HST photometry and VLT spectroscopy is able to provide estimates of host galaxy stellar mass that are sufficiently accurate for use in a mass-step correction in the cosmological analysis.

description: We study several properties of blazars detected in the gamma-ray energy range by comparing the EGRET sources with a sample of radio blazars which can be considered possible gamma-ray candidates. We define three classes: non-gamma-ray blazars, blazars with quasi-steady gamma-ray emission, and gamma-ray blazars with substantial activity level. By combining the information of detected and candidate AGNs, we characterise the blazar activity, including the discovery of a region of consistency between the gamma-ray flaring duty-cycle and the recurrence time between flares. We also find a possible relation between the activity index of FSRQs and their black hole mass.

description: We report on tunneling experiment between two quantum Hall droplets separated by a nearly ideal tunnel barrier. The device is produced by cleaved edge overgrowth that laterally juxtaposes two two-dimensional electron systems across a high quality semiconductor barrier. The dramatic evolution of the tunneling characteristics is consistent with the magnetic field-dependent tunneling between the coupled edge states of the quantum Hall droplets. We identify a series of quantum critical points between successive strong and weak tunneling regimes that are reminiscent of the plateau-transitions in quantum Hall effect. Scaling analysis shows that the conductance near the critical magnetic fields $B_{c}$ is a function of a single scaling argument $|B-B_{c}|T^{-κ}$, where the exponent $κ= 0.42$. This puzzling resemblance to a quantum Hall-insulator transition points to the significance of interedge correlation in the lateral tunneling of quantum Hall droplets.

Production of $ω$ mesons in pp collisions at $\sqrt{s}$ = 7 TeV

description: The invariant differential cross section of inclusive $ω(782)$ meson production at midrapidity ($|y|<0.5$) in pp collisions at $\sqrt{s}$ = 7 TeV was measured with the ALICE detector at the LHC over a transverse momentum range of 2 < $p_{\rm{T}}$ < 17 GeV/$c$. The $ω$ meson was reconstructed via its $ω\rightarrowπ^+π^-π^0$ decay channel. The measured $ω$ production cross section is compared to various calculations: PYTHIA 8.2 Monash 2013 describes the data, while PYTHIA 8.2 Tune 4C overestimates the data by about 50%. A recent NLO calculation, which includes a model describing the fragmentation of the whole vector-meson nonet, describes the data within uncertainties below 6 GeV/$c$, while it overestimates the data by up to 50% for higher $p_{\rm{T}}$. The $ω/π^0$ ratio is in agreement with previous measurements at lower collision energies and the PYTHIA calculations. In addition, the measurement is compatible with transverse mass scaling within the measured $p_{\rm{T}}$ range and the ratio is constant with $C^{ω/π^{0}}$ = 0.67 $\pm$ 0.03 (stat) $\pm$ 0.04 (sys) above a transverse momentum of 2.5 GeV/$c$.

description: In rapidly suburbanizing areas, minimum lot sizes of ten acres or greater are often used to discourage residential development and to maintain agricultural critical mass. Because of significant development pressure in these places, there is a good chance these lot size regulations will bind. Such “down-zoning” often appears alongside the purchase of agricultural and conservation easements that reduce housing development even more. Whatever the benefits of such policies for agriculture and the environment, they raise obvious concerns about housing supply and affordability. The issue of affordability should be analyzed at the regional scale, since we would normally expect some high-income, low density enclaves to exist within any metropolitan area. In addition, the analyst should look beyond median home price to compare the distribution of a region’s available housing stock to the distribution of its income. A primary hypothesized effect of large-lot zoning is that it skews the distribution of available housing upward relative to the distribution of income. The present study will use a unique dataset on the New Jersey Highlands region to help answer the fundamental question posed by its title. This dataset includes historical data on the lot size minima imposed on every residential acre in the 83 Highlands municipalities, as well as real estate listing data on thousands of residential transactions in these 83 municipalities. Data from the U.S. Census are used to examine the distribution of income among New Jersey residents who ought to be served by the housing stock in the Highlands. The study finds that in the 1990s and 2000s, the stock of Highlands housing was skewed high relative to the metropolitan incomes available to purchase it, even with renters excluded from the analysis. Using a simple threshold of three times household income, the bottom 30% of households were consistently able to afford fewer than 30% of the homes coming on the market, while the top earners could afford a disproportionately large share of the available housing. At the same time, the study was unable to document a deterioration in Highlands housing affordability in the 1990s and 2000s that was attributable to anything other than the national housing bubble. Down-zoning is likely to affect the mix of housing types on the margin, while the majority of real estate transactions involve homes that were built several decades ago. This suggests either a separate analysis of new construction, or a longer time series on home types and prices that would capture the effects of restrictive zoning over several decades.
Collective excitations in the inner crust of neutron stars : supergiant resonances

description: We investigate the nuclear collective excitations of Wigner-Seitz cells containing nuclear clusters immersed in a gas of neutrons. This baryonic non-uniform system is specific to the structure of inner crust matter of neutron stars. The collective excitations are studied in the framework of a spherical Hartree-Fock-Bogoliubov + Quasiparticle Random Phase Approximation, formulated in coordinate representation. The calculations are done for two representative Wigner-Seitz cells with baryonic density equal to 0.02 fm$^{-3}$ and 0.08 fm$^{-3}$. It is shown that the excitations with low multipolarities are concentrated almost entirely in one strongly collective mode which exhausts a very large fraction of the energy-weighted sum rule. Since these collective modes are located at very low energies compared to the giant resonances in standard nuclei, they may affect significantly the specific heat of baryonic inner crust matter of neutron stars.

description: Under the Food, Conservation, and Energy Act of 2008 (Farm Act), U.S. farms with 10 or fewer base acres became ineligible to receive Direct and Countercyclical Payment (DCP) or Average Crop Revenue Election (ACRE) program payments(Section 1101(d) and 1302(d)) from USDA. Limited resource and socially disadvantaged owners are exempt from this “base 10” provision. Eliminating payments on farms with 10 or fewer base acres reduces payments made by USDA Farm Service Agency (FSA) and the cost of administering the DCP and ACRE programs. We examine the characteristics of the farms affected by the limited base acre provision and answer the question: How does the provision affect small farms?
Accretion discs with non-zero central torque

description: We present analytical and numerical solutions for accretion discs subject to a non-zero central torque. We express this in terms of a single parameter, $f$, which is the ratio of outward viscous flux of angular momentum from the inner boundary to the inward advected flux of angular momentum there. The standard "accretion" disc, where the central boundary condition is zero-torque, is represented by $f=0$. A "decretion" disc, where the radial velocity at the inner boundary is zero, is represented by $f\rightarrow\infty$. For $f > 0$ a torque is applied to the disc at the inner boundary, which feeds both angular momentum and energy into the disc. This can arise, for example, in the case of a circumbinary disc where resonances transfer energy and angular momentum from the binary to the disc orbits, or where the disc is around a rotating magnetic star which can allow the disc orbits to be accelerated outwards at the magnetospheric radius. We present steady-state solutions to the disc structure as a function of $f$, and for arbitrary kinematic viscosity $ν$. For time-dependent discs, we solve the equations using a Green's function approach for the specific case of $ν\propto R$ and provide an example numerical solution to the equations for the case of $ν\propto R^{3/2}$. We find that for values of $f\lesssim 0.1$ the disc solutions closely resemble "accretion" discs. For values of $f \gtrsim 10$ the solutions initially resemble "decretion" discs, but at sufficiently late times exhibit the properties of "accretion" discs. We discuss the application of this theory to different astrophysical systems, and in particular the values of the $f$ parameter that are expected in different cases.

description: In this paper we examine the issue of permanence in the context of sequestering carbon through afforestation. We develop a dynamic nested optimal control model of carbon sequestration associated with the decision to afforest a tract of land given there are uncertainties associated with fire and insect/disease hazards. Conceptually, these potential hazards are similar in that their occurrence at any time t is uncertain and landowners can take specific actions – although generally different actions - in any time period t to reduce the probability of sustaining losses related to them. The hazards differ, however, in that fire represents a large loss in carbon at a moment in time, while insect/disease infestations are more likely to be reflected in a period of significant slowing of the rate of carbon accumulation than was anticipated followed by a sustained period of slowly decreasing carbon losses. The nature of these losses will influence the design of incentives under GHG mitigation frameworks that require carbon losses to be replaced as well as the strategies farmers adopt to deal with the uncertainties associated with these events occurring.

description: Cardiovascular diseases (CVD) cost Americans hundreds in billions of dollars. High cholesterol levels, which are closely related to diet habits, are a major contributor to CVD. In this paper we study whether changes in food prices are related to cholesterol levels and whether taxes or subsidies of particular foods would be effective in lowering cholesterol levels and, consequently, CVD costs. We find that prices of vegetables, processed foods, and whole milk and whole grains significantly affect the blood cholesterol levels. Having analyzed the costs and benefits of government interventions, we find that a subsidy of vegetables and whole grains would be the most efficient way to reduce CVD expenditures.

(2017) and Doellman et al. (2019), and reanalyzed using the 44,749 SNPs called in this study. Scatterplots depict the relationship between the difference in allele frequency between late versus early eclosing samples of hawthorn flies (x-axis; eclosion time GWAS) and the difference in allele frequency between Urbana, Illinois (south) and Fennville, Michigan (north) study sites (y-axis; geographic cline). (A) graph for all SNPs genotyped in the study (r=0.446, P<0.0001, n=44,749 SNPs); and (B) graph for SNPs mapping to chromosomes 1-3 (gray circles; r=0.756, P<0.0001, n=2,102 SNPs) and those mapping to chromosomes 1–3 characterized as belonging to the high linkage disequilibrium (high LD) class of loci (orange circles; r=0.825, P<0.0001, n=508 SNPs). Positive slopes of relationships indicate that SNPs associated with later eclosion time (and associated with greater initial diapause intensity for chromosomes 1–3; Calvert et al. submitted) are present in higher frequency in more southern than northern populations of the hawthorn race. In addition, the relationship is strongest for the high LD SNPs on chromosomes 1–3, which are associated with inversion polymorphism in R. pomonella that has been hypothesized to take the form of clinal variation due to past geographic isolation, divergence, and secondary contact between hawthorn-infesting populations in Mexico and the USA (Feder et al. 2003).

description: We classify the ODEs that correspond to elliptic CR-manifolds with maximal isotropy. It follows that the dimension of the isotropy group of an elliptic CR-manifold can be only 10 (for the quadric), 4 (for the listed examples) or less. This is in contrast with the situation of hyperbolic CR-manifolds, where the dimension can be 10 (for the quadric), 6 or 5 (for semi-quadrics) or less than 4. We also prove that, for all elliptic CR-manifolds with non-linearizable istropy group, except for two special manifolds, the points with non-linearizable isotropy form exactly some complex curve on the manifold.

description: A nested logit model was used to analyze the 2009 Southern Cotton Precision Farming Survey to study the impact of farmer and farm characteristics on the adoption of Variability Detection Technologies (VDT) and the adoption of Variability Rate application Technology (VRT) conditioned on the type of the VDT chosen. The results showed that the farm size and exposure to extension activities are important factors affecting the choice of VDTs. The farmers adopting both soil and plant based VDTs are more likely to adopt VRT. The probability of adoption of VRTs was lower for Texas cotton farmers irrespective of the type of VDT adopted. In general, younger, more educated farmers who use computers for farming operations are more likely to adopt VRT when they choose soil based or both soil and plant based VDT.

description: Exogenous, unobserved factors often confound the effects of alliance networks. More capable farmers might be less likely to exit and more likely to have a large number of alliances. In this case the negative correlation between alliance network size and exit likelihood is due to the unobserved confounder--farmer ability--not the effect of network size on exit likelihood. Recognizing the endogeneity of alliance network size when determining a farm’s survival likelihood, we employ an empirical model that accounts for the bias caused by unobserved effects. We account for time-invariant unobserved effects with individual fixed effects. We control for county-level confounding factors with a time-varying county effect. Finally, we address unobserved, time-varying confounding factors by including alliance network size as a control variable. As a control variable, alliance network size captures all remaining confounding factors. We estimate the alliance network effect by interacting the alliance network size with a weather index. In this way we isolate the “insurance effect” of having a large alliance network. We answer the question, “given a farmer’s alliance network size, what is the likelihood of exiting when experiencing an extreme weather event.” We employ USDA-Farm Services Agency administrative data to measure farmer alliances and farm entry and exit. The data provide detailed information on every farm-payment recipient since 1990, including location and organizational structure. We use the organizational-structure information to map farmer alliances and characterize alliance networks according to their size (number of nodes and number of members in each node), contractual choice (i.e. joint ventures), geographic scope, and commodity scope. Our preliminary results confirm the positive correlation between network size and farm survival.

description: In this paper we introduce and study some geometric objects associated to Artin monoids. The Deligne complex for an Artin group is a cube complex that was introduced by the second author and Davis (1995) to study the K(π,1) conjecture for these groups. Using a notion of Artin monoid cosets, we construct a version of the Deligne complex for Artin monoids. We show that for any Artin monoid this cube complex is contractible. Furthermore, we study the embedding of the monoid Deligne complex into the Deligne complex for the corresponding Artin group. We show that for any Artin group this is a locally isometric embedding. In the case of FC-type Artin groups this result can be strengthened to a globally isometric embedding, and it follows that the monoid Deligne complex is CAT(0) and its image in the Deligne complex is convex. We also consider the Cayley graph of an Artin group, and investigate properties of the subgraph spanned by elements of the Artin monoid. Our final results show that for a finite type Artin group, the monoid Cayley graph embeds isometrically, but not quasi-convexly, into the group Cayley graph.

description: Linkage disequilibrium (LD) network plots for SNPs mapping to chromosomes 1–5, demonstrating correspondence between high LD loci between R. pomonella and R. mendax. Loci are shown as nodes (circles) connected to one another in clusters by edges, when pairwise LD (r2) between loci exceeds 0.8. Tight clusters indicate this high pairwise LD between many SNPs, while unconnected SNPs have a pairwise LD below 0.8 with all other SNPs on the same chromosome. Within population LD is represented for the hawthorn host race of R. pomonella (panels A-E) and the blueberry-infesting population of R. mendax (panels F-J). Black circles represent high LD SNPs residing in the putative inversions segregating within R. pomonella. Note that on chromosomes 3 and 5, many of the SNPs in the high LD clusters in R. pomonella are also in high LD with one another in R. mendax. This suggests that the two species share large inversion polymorphisms on these two chromosomes.
Bubbling 1/2 BPS solutions of minimal six-dimensional supergravity

description: We continue our previous analysis (hep-th/0412045) of 1/2 BPS solutions to minimal 6d supergravity of bubbling form. We show that, by turning on an axion field in the T^2 torus reduction, the constraint F \wedge F, present in the case of an S^1 x S^1 reduction, is relaxed. We prove that the four-dimensional reduction to a bosonic field theory, whose content is the metric, a gauge field, two scalars and a pseudo-scalar (the axion), is consistent. Moreover, these reductions when lifted to the six-dimensional minimal supergravity represent the sought-after family of 1/2 BPS bubbling solutions.

It takes a community to raise a child : income support programs and lone mothers
Creators: name: Blown, Suzanne Carys
Publisher: name: University of British Columbia
Year: 2009

description: This thesis employs a comparative framework for examining two different approaches to income support for lone mothers: the current British Columbia (BC) model and the current Swedish model. The two models are based within their respective traditions of the welfare state. Each approach represents a distinctive response to the prevalent economic vulnerability of lone mothers. In order to compare the models, I pose questions related to feminization of poverty, to tensions between worker and parent roles, and to notions of citizenship. Drawing on lessons learned from the BC and Swedish model, this thesis then explores an alternative, community development approach that incorporates principles of social justice and ecological sustainability in the goal of economic security for lone mothers. Lastly, I offer conclusions and planning implications.

description: Exchange interactions between $S=\frac{1}{2}$ sites in piperazinium hexachlorodicuprate produce a frustrated bilayer magnet with a singlet ground state. We have determined the field-temperature phase diagram by high field magnetization and neutron scattering experiments. There are two quantum critical points: $H_{c1}=7.5$ T separates a quantum paramagnet phase from a three dimensional, antiferromagnetically-ordered state while $H_{c2}=37$ T marks the onset of a fully polarized state. The ordered phase, which we describe as a magnon Bose-Einstein condensate (BEC), is embedded in a quantum critical regime with short range correlations. A low temperature anomaly in the BEC phase boundary indicates that additional low energy features of the material become important near $H_{c1}$.

description: The nitrogen cascade concept indicates that agriculture serves as a significant link between emissions of the potent greenhouse gas (GHG) nitrous oxide and losses of nitrate-N to surface waters. Conservation practices have the potential to exploit this link, as their implementation is found to reduce fluxes of GHGs and nonpoint source (NPS) water pollution. Several studies have recognized this link and have documented the potential to improve environmental quality through the use of programs which retire land, the cost of which can be offset by the sale of carbon credits. However, the ability to use land for both agricultural production and environmental conservation is important. As such, this study provides a novel analytical framework that is used to examine the potential for implementing agricultural conservation practices to reduce NPS water pollutants and fluxes of GHGs in a working-lands setting. The extent to which carbon pricing can affect practice implementation costs and the optimal distribution of these practices throughout the watershed is also explored. Results from this study indicate that carbon offsets can sharply reduce conservation practice implementation costs and therefore have the potential to reduce greater amounts of NPS pollution for a given cost of implementation. This conclusion has significant implications for policymaking, particularly with regard to using market mechanisms to improve water quality in watersheds where markets have historically been unsuccessful. However, this study found that the optimal allocation of practices was heavily reliant on fertilizer management, which is difficult to enforce in practice.
