Calvia andrewesi

description: Calvia andrewesi (Weise)
(Figs 31, 197)
Anisocalvia andrewesi Weise, 1908: 220 (Lectotype female, BMNH; Type locality: Anamalai Hills); Booth 1997: 929.
Calvia andrewesi: Korschefsky 1932: 521; Booth 1997: 929; Poorani 2002a: 322.
Diagnosis. Length: 5.50–6.00 mm; width: 5.20–5.50 mm. Form broadly oval to subcircular, dorsum strongly convex, glabrous. Ground colour yellowish (Figs 31a, 197f–i) or reddish brown (Fig. 31c) or dark brown with paler elytral margins (Fig. 31b), elytra unmarked or yellow with black spots arranged in a 1-2-2-1 pattern (Fig. 31a). Elytra with strong dual punctation (Fig. 31f). Abdominal postcoxal line incomplete (Fig. 31d), parallel to posterior margin of ventrite 1. Male genitalia (Fig. 31h–k) and spermatheca (Fig. 31g) as illustrated.
Life stages. Life stages as illustrated in Fig. 197.
Distribution. India: Endemic to the Western Ghats (Anamalai Hills, Nilgiris).
Prey / associated habitat. Collected in association with Greenidea sp. (Aphididae) on jack fruit (label data).
Seasonal occurrence. Collected in April, January (label data).
Note. It is a variable species, very similar to Calvia punctata (Mulsant), a species found in north and northwestern India and the Himalayas, in terms of size and dual punctation of elytra, but differs from it by the more rounded and strongly convex form. Iablokoff-Khnzorian (1979, 1982) considered it as a synonym of the latter, but Booth (1997) confirmed it as a valid species based on the more strongly rounded and convex form and the distinct male genitalia and designated a lectotype.

description: This article focuses on the demand system of French farmers concerning pesticides uses. We estimate the demand elasticities of herbicides, insecticides and fungicides with respect to pesticide expenditure, and considering crop differentiation. Then we compare two indexes that are used in agronomic literature to measure the intensity of pesticides uses. We retain a Linear Approximated Almost Ideal Demand System (LA/AIDS) specification. A Full-Information Maximum Likelihood estimation procedure is used for dealing with the problem of censored dependent variable. We consider two cross-sections observed in 2001 and 2006 covering pesticides uses of three crops. We confirm the previous results of the literature that farmers response to price variation is very low, with higher prices response in 2006 than in 2001. Moreover, we find that conditional herbicides expenditure elasticities are often higher than insecticides expenditure elasticities, but lower than those of fungicides. We find higher own-price elasticities for herbicides and fungicides than for insecticides, which is the less used. Finally, application dose seems statistically better to explain herbicides decision, whereas treatment frequency index appears better for insecticides and fungicides. However, most of elasticities are closed for dose and treatment frequency index.

description: We derive generalization error bounds for traditional time-series forecasting models. Our results hold for many standard forecasting tools including autoregressive models, moving average models, and, more generally, linear state-space models. These non-asymptotic bounds need only weak assumptions on the data-generating process, yet allow forecasters to select among competing models and to guarantee, with high probability, that their chosen model will perform well. We motivate our techniques with and apply them to standard economic and financial forecasting tools---a GARCH model for predicting equity volatility and a dynamic stochastic general equilibrium model (DSGE), the standard tool in macroeconomic forecasting. We demonstrate in particular how our techniques can aid forecasters and policy makers in choosing models which behave well under uncertainty and mis-specification.

description: In this paper, we examine conditional, forecast-based dynamic pest management in agricultural crop production given stochastic pest infestations and stochastic climate dynamics throughout the growing season. Using stochastic optimal control we show that correlation between forecast error for climate prediction and forecast error for pest outbreaks can be used to improve pesticide application efficiency. In the general setting, we apply modified Hamiltonian approach to discuss the steady state equilibrium. Given specific functional forms, a closed form solution can be found for the stochastic optimal control problem. Moreover, we find conditions for model parameters so that the optimal pesticide usage path will be monotonically increasing or decreasing in the correlation coefficient between climate forecast errors and pest growth disturbances.

description: This research gauges the ability of deep reinforcement learning (DRL) techniques to assist the optimization and control of fluid mechanical systems. It combines a novel, "degenerate" version of the proximal policy optimization (PPO) algorithm, that trains a neural network in optimizing the system only once per learning episode, and an in-house stabilized finite elements environment implementing the variational multiscale (VMS) method, that computes the numerical reward fed to the neural network. Three prototypical examples of separated flows in two dimensions are used as testbed for developing the methodology, each of which adds a layer of complexity due either to the unsteadiness of the flow solutions, or the sharpness of the objective function, or the dimension of the control parameter space. Relevance is carefully assessed by comparing systematically to reference data obtained by canonical direct and adjoint methods. Beyond adding value to the shallow literature on this subject, these findings establish the potential of single-step PPO for reliable black-box optimization of computational fluid dynamics (CFD) systems, which paves the way for future progress in optimal flow control using this new class of methods.
Sociopolitical economy, identities, and roles in planning local environmental projects : cases from Kazakhstan
Creators: name: Emmert, Jason Daniel
Publisher: name: University of British Columbia
Year: 2009

description: Multilateral and bilateral development agencies in cooperation with local partners have implemented hundreds of local environmental projects in Kazakhstan since its independence in 1991. This thesis presents case studies of four environmental projects, identifying some of the power dynamics around the projects and exploring how they have shaped and influenced project outcomes as well as social relationships among actors. From data gathered through in-depth personal interviews with project actors and participant observation of projects, the thesis presents and analyses a range of roles, identities and contexts as determining and explanatory factors for power dynamics and, by extension, project outcomes. The findings present evidence that power dynamics, through their relation to and dependence on roles, identities and contexts, have a determining impact on the link between project purpose and outcomes negotiated in the project planning process. Specifically, the findings suggest that relative power is dependent on the roles actors play in the planning process, that these roles are shaped by the identities of the actors, and that all of these are specifically defined by the larger socioeconomic context. Consequently, actors within their roles may possess differentiated levels of relative power, which in turn affect their abilities to shape processes, define goals, and achieve outcomes within the strategic bargaining context of project planning. The findings highlight the importance of examining and including the redistribution of the various forms of power in future projects as an explicit project outcome, through a better understanding of the existing and future relationships and the dynamics of power among actors; the usefulness of recognizing identities and their contribution to shaping power structures and strengthening project continuity; and the necessity of explicit recognition of how/why knowledge is legitimized as an important link between identity, roles, and power.

description: We analyse weekly calf prices from 2003 to 2009 to assess the impact of two important events which changed the structure of European cattle markets. We find the four European calf markets studied to be integrated. The decoupling of farm payments in the framework of the 2003 reforms of the Common Agricultural Policy is found to reduce prices. We ascertain that the outbreak of the Blue Tongue disease induced a structural change in some of the markets. Using counterfactual scenarios, we provide an indication of the effects resulting from granting member states a high degree of discretion in implementation.

description: Farmers and consumers suspect that processing firms abuse their power in the milk marketing chain. We employ threshold autoregressive and moment threshold autoregressive tests and contrary to expectations find evidence of a downward trend in UHT milk real price without a corresponding decline in farm-gate prices. The downward trend coincides with increased competition in the dairy industry and with the growing market share of the formal sector at the expense of the informal sector. Major dairy processing firms expand their market share and still enjoy healthy profits thanks to increasing returns to scale in processing and distribution in a growing market.

description: The beneficiaries of technology adoption in agriculture and biofuels markets in the United States are heavily influenced by domestic biofuel policies and market context. Biofuel mandates, one of the key pillars of domestic biofuel policies, may significantly alter the elasticity of demand for biofuels as well as the derived demand for maize used to produce a significant share of ethanol in the United States. Using a stochastic agriculture and biofuels model, we assess how the introduction of technology may affect the crops and biofuel markets under binding and non-binding biofuel mandates and discuss the implications for analysis of EU biofuel policies.

description: Previous analyses of dairy farm structural change focused on the variation over time in one or a small number of regions. Here we present an EU-15-wide analysis of the change of the number of farms in different size classes. The purpose is (1) to identify the differences in regional development patterns and (2) to measure the explanatory relevance and effect of key factors suggested in the literature. Apart from the unprecedented scope, the underlying Markov chain analysis also contributes by combining observed transitions in micro data with macro data on farm numbers. Results show widely significant impacts of most explanatory variables, but also reveal the complexity of the underlying processes.

description: This paper analyses factors influencing Scottish dairy farmers’ intentions to change size of business in response to milk quota abolition. The analysis uses structural equation modelling and is based on survey data collected in 2009 through telephone interviews with 533 farmers. Results suggest that farmers who (1) intend to leave their farm to children; (2) have not inherited their farm from previous generation; (3) perceive a lower impact of milk quota abolition on business; (4) have less negative attitudes towards policies/regulations; and (5) perceived a lower influence of policies/markets on business during the past decade are most likely to increase farm size.

description: Economies of scale and scope are often not exploited in Western agriculture. A general reason is probably that various types of transaction costs limit coordination among farmers. A more specific explanation is that coordination on land markets or machinery cooperation is difficult to achieve when farmers are heterogeneous as some kind of price differentiation is necessary for a Pareto-superior solution. This paper investigates experimentally such a coordination game with heterogeneous agents using an example inspired by agricultural land markets. The experimental findings suggest that a Pareto-optimal solution may not be found when agents are heterogeneous. The findings provide evidence for market failures and cooperation deficits as reasons for unexploited economies of scale in agriculture. Our findings are consistent with coordination failures that appear to be driven by behavioural factors such as anchoring-and-adjustment, inequity aversion, and a reverse form of winner’s curse.

Impact of iron-catalyzed dietary lipid peroxidation on growth performance, general health and flesh proximate and fatty acid composition of atlantic salmon (salmo salar) in sea water
Creators: name: Sutton, Jill
Publisher: name: University of British Columbia
Year: 2009

description: Post-juvenile Atlantic salmon (Salmo salar) were fed to satiation, twice daily for 126 days,with diets supplemented with copper (10 or 35 mg/kg), iron (333 or 1000 mg/kg)/'and unoxidized or oxidized dietary lipid measured as peroxide value (PV, <5 or <5+ or 35+ meq/kg). The dietary effects measured include growth performance, general health, flesh proximate and fatty acid composition, and in situ oxidative stress. Lipid peroxidation in the fishmeal and fish oil was controlled by adding ethoxyquin (150 mg/kg) to diets containing unoxidized dietary lipid (<5 meq/kg). All diets contained the required level of vitamin E (30 IU/kg). Diets supplemented with the highest level of iron, without anti-oxidant protection (no ethoxyquin), showed the greatest loss of eicosapentaenoic (EPA) and docosahexaenoic acids (DHA) and vitamin E (p<0.05). Fish fed these diets displayed significantly (p<0.05) decreased growth, feed intake, feed efficiency, and utilization of gross energy and protein that were attributable to the losses of the preceding essential nutrients and possibly dietary protein modification. Dietary vitamin E concentrations decreased in all diets, except those with low levels of iron and peroxide values, during the 126-day study period. Diets without anti-oxidant supplementation had significantly (p<0.05) higher lipid peroxidation levels as compared with anti-oxidant-containing diets. However, fish hepatic and muscle tissue lipid peroxidation were unaffected. Autopsy-based assessments of general health indicate that fish fed diets influenced by iron-catalyzed lipid peroxidation exhibited clinical signs of poor health indicative of dietary vitamin E and omega-3 highly unsaturated fatty acid deficiency. These results suggest that fish diets undergoing ironcatalyzed lipid peroxidation with attendant deficiencies in omega-3 highly unsaturated fatty acids and vitamin E adversely influence the growth performance, general health, and fillet proximate and fatty acid composition of post-juvenile Atlantic salmon. The consumption of oxidized dietary lipids by the experimental fish did not influence in situ oxidative stress parameters as measured in this study.

description: The development of multi-agent models for agriculture has allowed the inclusion of farm decision-making behaviour and interactions in the simulation of smaller agricultural regions. Important methodological impact for this has come in particular from scientists from Germany. Currently under construction, the SWISSland model claims to depict as realistically as possible the 50,000 family farms comprising the whole of Swiss agriculture in all their heterogeneity as regards farm and cost structures as well as farm decision behaviours, with the aim of improving the simulation and forecasting of structural change. This paper describes methodological aspects in the formation of the agent population by combining various data sources such as accounting and spatial data and the results of surveys. As its basis, SWISSland uses the 3300 Swiss Farm Accountancy Data Network (FADN) farms, whose representativeness is substantially improved by means of a corrective procedure. Individual-farm optimisation models simulate the heterogeneous behaviour of the agents, for whom a potential exists for land trade within regional groups. With the linking of different methods and recorded data, we can expect to see a marked increase in the quality of the assessment of policy consequences.
Damped Lyman alpha Absorbing Galaxies At Low Redshifts z<1 From Hierarchical Galaxy Formation Models

Subjects: subject: Astrophysics (astro-ph)

description: We investigate Damped Ly-alpha absorbing galaxies (DLA galaxies) at low redshifts z<1 in the hierarchical structure formation scenario to clarify the nature of DLA galaxies because observational data of such galaxies mainly at low redshifts are currently available. We find that our model well reproduces distributions of fundamental properties of DLA galaxies such as luminosities, column densities, impact parameters obtained by optical and near-infrared imagings. Our results suggest that DLA systems primarily consist of low luminosity galaxies with small impact parameters (typical radius about 3 kpc, surface brightness from 22 to 27 mag arcsec^{-2}) similar to low surface brightness (LSB) galaxies. In addition, we investigate selection biases arising from the faintness and from the masking effect which prevents us from identifying a DLA galaxy hidden or contaminated by a point spread function of a background quasar. We find that the latter affects the distributions of DLA properties more seriously rather than the former, and that the observational data are well reproduced only when taking into account the masking effect. The missing rate of DLA galaxies by the masking effect attains 60-90 % in the sample at redshift 0

description: Charge exchange (CX) emission reveals the significant interaction between neutral and ionized interstellar medium (ISM) components of the dense, multiphase, circumnuclear region of a galaxy. We use a model including a thermal and a CX components to describe the high-resolution XMM-Newton/RGS spectrum of the diffuse emission in the central region of M51. Representative signatures of CX emission -- especially the prominent OVII forbidden line and the excess emission in the OVIII Ly$γ$ lines -- can be well explained by the model. Combined with the Chandra images in the OVIII and the OVII bands, we find the soft X-ray emission is dominated by the jet-driven outflow and its interaction with the ambient neutral material. The jet-driven outflow itself is likely a thermal plasma of $\sim 0.59$ keV, with mostly sub-solar abundances. It runs into the ambient neutral gas, and produces significant CX emission that accounts for one-fifth of the diffuse X-ray emission in the 7--28 Å band. The effective interface area in the CX process is one order of magnitude greater than the geometrical surface area of the jet-driven outflow. The tenuous outflow driven by the nuclear star formation may also contribute a small portion to both the diffuse thermal and CX emission. The photoionization by the active galactic nuclei (AGNs) and the resonance scattering by the hot gas itself are disfavored, though the effects from past AGN events may not be ruled out.
Why liquids are fragile

description: The fragilities (Tg-normalized temperature dependence of alpha-relaxation times) of 33 glass-forming liquids and polymers are compared for isobaric, mP, and isochoric, mV, conditions. We find that the two quantities are linearly correlated, mP = (37 +/- 3) + (0.84 +/- 0.5)mV. This result has obvious important consequences, since the ratio mV/mP is a measure of the relative degree to which temperature and density control the dynamics, Moreover, we show that the fragility itself is a consequence of the relative interplay of temperature and density effects near Tg. Specifically, strong behavior reflects a substantial contribution from density (jammed dynamics), while the relaxation of fragile liquids is more thermally-activated. Drawing on a scaling law, a physical interpretation of this result in terms of the intermolecular potential is offered.

description: After discussing generally models in ecology and economics that combine competition, optimization and evolution, this article concentrates on models of intraspecific competition. It demonstrates the importance of diversity/inequalities within populations of species and other environments for the sustainability of their populations, given the occurrence of environmental change. This is demonstrated both for scramble (open-access) and contest competition. Implications are drawn for human populations and for industrial organization. The possibility is raised that within industry competition may not always exist between firms in all stages of the development of a new industry. Policy implications are considered. For example, it is argued that policies designed to encourage intense business competition and maximum economic efficiency have the drawback of eventually making industries highly vulnerable to exogenous economic changes.

description: In an earlier note, Collins and Tisdell (2002b) explored the possibility of a long-run relationship between Australian business returns and international business travel. Using annual data they found that such a relationship exists. The purpose of this study is to further examine this relationship using quarterly data for the time frame 1974:1 to 1999:4. In addition, previous studies on international business travel have offered some but not strong evidence for the existence of a positive relationship between the level of international business travel and real GDP of the origin country. This study suggests that the aggregate return on business investments is a superior predictor of international business travel than GDP. The Engle-Granger and Johansen’s maximum-likelihood cointegration procedures are used to show a long-term relationship exists between Australian outbound business travel and Australian business returns, but not with Real Australian GDP. Reasons for this relationship are discussed.

We perform a suite of N-body simulations of such massive clusters using three different direct-summation N-body codes, exploring different Galactic orbits and particle numbers. By inspecting the rate at which a star's energy changes as it becomes energetically unbound from the cluster, we can neatly identify two populations we call kicks and sweeps, that escape through two-body encounters internal to the cluster and the external tidal field, respectively. We find that for a typical halo globular cluster on a moderately eccentric orbit, sweeps are far more common than kicks but the total mass loss rate is so low that these clusters can survive for tens of Hubble times. The different N-body codes give largely consistent results, but we find that numerical artifacts may arise in relation to the time step parameter of the Hermite integration scheme, namely that the value required for convergent results is sensitive to the number of particles.

description: Starting from the establishment of the People’s Republic of China in 1949, this article provides background on China’s science and technology (S&T) system and the perceived growing urgency of reforming it in order to support continuing economic growth in China. The need for reform became even more pressing once China commenced its market-oriented economic reforms in 1979. Comparative data are provided on China’s S&T sector, the processes of reforming China’s S&T system is outlined and discussed as well as changing patterns in the source of funds for its S & T research. China’s evolving technology market is given particular attention as well as its establishment of a patent system. The importance of closer ties between technology suppliers and users in China, as well as pitfalls, are given particular attention. Transition in the system has been gradual rather than of a ‘big-bang’ type. The process of reforming the system and the state of China’s current S & T system are assessed.
Efficient Public Provision of Commodities: Transaction Costs, Bounded Rationality and Other Considerations

description: After briefly reviewing recent economic theories about the economic welfare consequences of public provision of private commodities, this article examines the cost efficient supply of publicly provided commodities. In the light of the presence of transaction costs and bounded rationality, and consequences for the competence of public bodies, it considers whether the following are cost effective: (1) increased out-sourcing of government funded work and supplies using market and competitive mechanisms; (2) greater contestability of employment in the public sector; (3) more widespread imposition of user charges for publicly supplied commodities; and (4) the increased use of performance budgeting and accounting in the public sector. These measures are often favoured by proponents of structural adjustment policies as means to increase the economic efficiency of the public sector. However, it is argued here that such measures can potentially reduce the economic efficiency of the public sector rather than increase it.

description: This article concentrates on the global location of production of television receivers as a case study. The aim is to see if this accords with Vernon’s international product cycle theory or whether some modifications of the theory are required. The historical evolution of the global television industry is outlined and the global pattern of demand for television sets is explored, partly to relate the location of demand to the location of television production. Production cycles involved in television manufacture and its international location are then carefully explored both for black-and-white sets and for colour television. China’s rise to become the world’s major producers of television sets is given particular attention. Conclusions are drawn about the continuing relevance of the international product cycle and the need to modify Vernon’s original perceptions about it.
On the star arboricity of hypercubes

description: A Hypercube $Q_n$ is a graph in which the vertices are all binary vectors of length n, and two vertices are adjacent if and only if their components differ in exactly one place. A galaxy or a star forest is a union of vertex disjoint stars. The star arboricity of a graph $G$, ${\rm sa}(G)$, is the minimum number of galaxies which partition the edge set of $G$. In this paper among other results, we determine the exact values of ${\rm sa}(Q_n)$ for $n \in \{2^k-3, 2^k+1, 2^k+2, 2^i+2^j-4\}$, $i \geq j \geq 2$. We also improve the last known upper bound of ${\rm sa}(Q_n)$ and show the relation between ${\rm sa}(G)$ and square coloring.

Anisotropic Distribution of SDSS Satellite Galaxies: Planar (not Polar) Alignment

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: The distribution of satellite galaxies relative to isolated host galaxies in the Sloan Digital Sky Survey (SDSS) is investigated. Host-satellite systems are selected using three different methods, yielding samples of ~3300, ~1600, and \~950 satellites. In the plane of the sky, the distributions of all three samples show highly significant deviations from circular symmetry (> 99.99%, > 99.99%, and 99.79% confidence levels, respectively), and the degree of anisotropy is a strong function of the projected radius, r_p, at which the satellites are found. For r_p < 100 kpc, the SDSS satellites are aligned preferentially with the major axes of the hosts. This is in stark contrast to the Holmberg effect, in which satellites are aligned with the minor axes of host galaxies. The degree of anisotropy in the distribution of the SDSS satellites decreases with r_p and is consistent with an isotropic distribution at of order the 1-sigma level for 250 kpc < r_p < 500 kpc.

Transaction Costs and Bounded Rationality - Implications for Public Administration and Economic Policy

description: Relationships between bounded rationality and transaction cost theories are discussed and their connections with stochastic theories of industrial evolution are considered. While these theories have their limitations, they are useful but have been ignored in many public policy prescriptions, especially those involving markets. For example, as discussed, these theories have failed, on the whole, to influence competition policy and the design of more efficient systems for public administration (contracting out, labour contracts for public employment, adoption of the user-pays principle and use of performance budgeting and accounting), as well as in policies to remove market frictions. The result may be less efficient systems than otherwise achievable and diminished long-term economic performance. It is also pointed out that market transaction costs are sometimes important contributors to improving the performance of market systems by increasing their stability. The presence of frictions and diversity of behaviours can sometimes improve the long-run performance of competitive systems.

description: We present an equation-free computational approach to the study of the coarse-grained dynamics of {\it finite} assemblies of {\it non-identical} coupled oscillators at and near full synchronization. We use coarse-grained observables which account for the (rapidly developing) correlations between phase angles and oscillator natural frequencies. Exploiting short bursts of appropriately initialized detailed simulations, we circumvent the derivation of closures for the long-term dynamics of the assembly statistics.

description: Large spin Hall angles have been observed in 3d ferromagnets, but their origin, and especially their link with the ferromagnetic order, remain unclear. Here, we investigate the inverse spin Hall effect of Ni60Cu40 and Ni50Cu50 across their Curie temperature using spin pumping experiments. We evidence that the inverse spin Hall effect in these samples is comparable to that of platinum, and that it is insensitive to the magnetic order. These results points towards a Heisenberg localized model of the transition, and suggest that the large spin Hall effects in 3d ferromagnets can be independent of the magnetic phase.
