Fine-scale sea-ice modelling of the Storfjorden polynya, Svalbard

Abstract A polynya appears regularly in Storfjorden on the east side of the Svalbard archipelago. It is mainly forced by offshore winds and contributes around 10% of the brine water produced on Arctic shelves. We have applied a regional ocean model (ROMS), including a sea-ice model, on a fine grid (2 km) to simulate a full year of sea-ice growth and decay starting on 1 August 1999. This allows us to reproduce some key processes of the polynya opening and closing events during January–April 2000. The polynya remains open as long as the offshore winds exist, and reaches a width along the direction of the wind of 10–20 km. We suggest using a mean sea-ice thickness of <0.3m as the polynya criterion, as our simulations show varying strength in the horizontal gradients in sea-ice concentration and thickness. Results show a general freeze-up during December and January, with a mean polynya area during February–April within the fjord of 33 by 50 km, being 13% of the total fjord area. Some model results including sea-ice cover and drift speed can be partially validated using satellite imagery and field data, but in general are new measurements from the polynya interior needed to further improve the modelling of solid- and grease-ice processes.
Economic Assessment of Different Air-conditioning and Heating Systems for Electric City Buses Based on Comprehensive Energetic Simulations

The air-conditioning and heating of the passenger cabin in an electric bus leads to a significant increase of the auxiliaries’ energy consumption. Due to limited battery capacity, the daily operating range of electric buses depends considerably on the ambient climate. In particular, heating is an energy-intensive process since no waste heat from the IC engine is available. Energetic simulations show drastic range reductions when the interior is heated by an electric resistance heater. In contrast, the range reduction can be limited noticeably if a heat pump is utilised. Therefore, the selection of heating and air-conditioning (HVAC) systems has a significant impact not only on the range but also on the operating costs of an electric vehicle. The aim of this study is to conduct a cost analysis for different HVAC systems of an electric city bus. The economic assessment is based on comprehensive energy consumption simulation and a life-cycle costing approach considering all expenses of the operation period. The examination reveals that the heat pump systems feature significant energy savings compared to conventional HVAC systems. However, over a life span of twelve years, the current high acquisition cost of a heat pump system is not compensated when only considering direct cost.
Description of Weak Halogen Bonding Using Various Levels of Symmetry-Adapted Perturbation Theory Combined with Effective Core Potentials

The present work starts with providing a description of the halogen bonding (XB) interaction between the halogen atom of MH3X (where M = C–Pb and X = I, At) and the N atom of HCN. This interaction leads to the formation of stable yet very weakly bound MH3X⋯NCH complexes for which the interaction energy () between MH3X and HCN is calculated using various symmetry-adapted perturbation theory (SAPT) methods combined with the def2-QZVPP basis set and midbond functions. This basis set assigns effective core potentials (ECPs) not only to the I or At atom directly participating in the XB interaction with HCN but also to the M atom when substituted with Sn or Pb. Twelve SAPT methods (or levels) are taken into consideration. According to the SAPT analysis of , the XB interaction in the complexes shows mixed electrostatic-dispersion nature. Next, the accuracy of SAPT is evaluated by comparing with CCSD(T) reference data. This comparison reveals that high-order SAPT2
Mapping the distribution of dholes, Cuon alpinus (Canidae, Carnivora), in Thailand

Abstract No recent attempt has been made to survey dhole distribution, or to estimate remaining population numbers. We surveyed 15 protected areas in Thailand with camera traps from 1996 to 2010. We used the photo locations of dholes (n=96) in the maximum entropy (MaxEnt) model along with six environmental variables to model current dhole distribution, as well as species predictive occurrence layers for sambar, red muntjac, wild boar, tiger, and leopard. The MaxEnt model identified the predicted probability of the presence of leopards and sambar as positive and the most important variables in modeling dhole presence, indicating that maintaining a sufficient prey base may be the most important factor determining continued survival of dholes. Roughly 7% of the total land area in Thailand is potentially suitable for dholes. However, surveys to date have focused on protected areas, which make up just a third of the potential suitable areas for dholes. Only in four protected areas do they occur across the entire landscape, suggesting that in the majority of places where they occur, habitats are not uniformly suitable. Using the model, we identified several potential areas where dholes have not been reported, and therefore status surveys are needed, and where future research of the species might be focused.
Local Elections and Consumption Insurance: Evidence from Chinese Villages

While the literature on consumption insurance is growing fast, little research has been conducted on how rural consumption insurance is affected by democracy. In this paper the authors examine how consumption insurance of Chinese rural residents is affected if the local leader is democratically elected. Exploring a unique panel data set of 1,400 households from 1987 to 2002, they find that consumption insurance is more complete when the households are in villages with elected village leaders. Furthermore, democracy improves consumption insurance only for the poor and middle-income farmers, but not for the rich. These findings underline the importance of democratic governance for ensuring better rural consumption insurance and poverty reduction.
O C ] 2 5 M ay 2 01 7 Approximate and Stochastic Greedy Optimization

We consider two greedy algorithms for minimizing a convex function in a bounded convex set: an algorithm by Jones [1992] and the Frank-Wolfe (FW) algorithm. We first consider approximate versions of these algorithms. For smooth convex functions, we give sufficient conditions for convergence, a unified analysis for the well-known convergence rate of O(1/k) together with a result showing that this rate is the best obtainable from the proof technique, and an equivalence result for the two algorithms. We also consider approximate stochastic greedy algorithms for minimizing expectations. We show that replacing the full gradient by a single stochastic gradient can fail even on smooth convex functions. We give a convergent approximate stochastic Jones algorithm and a convergent approximate stochastic FW algorithm for smooth convex functions. In addition, we give a convergent approximate stochastic FW algorithm for nonsmooth convex functions. Convergence rates for these algorithms are given and proved.
PPAK Wide-field Integral Field Spectroscopy of NGC 628 – I. The largest spectroscopic mosaic on a single galaxy

We present a wide-field Integral Field Spectroscopy (IFS) survey on the nearby face-on Sbc galaxy NGC 628, comprising 11094 individual spectra, covering a nearly circular field-of-view of ∼6 arcmin in diameter, with a sampling of ∼2.7 arcsec per spectrum in the optical wavelength range (3700–7000 A). This galaxy is part of the PPAK IFS Nearby Galaxies Survey (PINGS). To our knowledge, this is the widest spectroscopic survey ever made in a single nearby galaxy. A detailed flux calibration was applied, granting a spectrophotometric accuracy of ∼0.2 mag. The spectroscopic data were analysed both as a single integrated spectrum that characterizes the global properties of the galaxy and using each individual spectrum to determine the spatial variation of the stellar and ionized gas components. The spatial distribution of the luminosity-weighted ages and metallicities of the stellar populations was analysed. Using typical strong emission-line ratios we derived the integrated and 2D spatial distribution of the ionized gas, the dust content, star formation rate (SFR) and oxygen abundance. The age of the stellar populations shows a negative gradient from the inner (older) to the outer (younger) regions. We found an inversion of this gradient in the central ∼1 kpc region, where a somewhat younger stellar population is present within a ring at this radius. This structure is associated with a circumnuclear star-forming region at ∼500 pc, also found in similar spiral galaxies. From the study of the integrated and spatially resolved ionized gas, we found a moderate SFR of ∼2.4 M⊙ yr−1. The oxygen abundance shows a clear gradient of higher metallicity values from the inner part to the outer part of the galaxy, with a mean value of 12 + log(O/H) ∼ 8.7. At some specific regions of the galaxy, the spatially resolved distribution of the physical properties shows some level of structure, suggesting real point-to-point variations within an individual H ii region. Our results are consistent with an inside–out growth scheme, with stronger star formation at the outer regions, and with evolved stellar populations in the inner ones.
Effect of fermentation conditions on content of phenolic compounds in red wine

Vladimir S. Puskas, Vladimir M. Kovac, Jelena M. Dodic and Sinisa N. Dodic The evidence of compounds that increase the nutritive value of red wines has been presented in a number of papers. These compounds include catechins and proanthocyanidins among others. Their protective effect on the cardiovascular system and anticarcinogenic properties has been proved. The effect of maceration conditions and increased solid grape parts content, seed in the first place, on the content of phenolic compounds of wine was investigated. Several micro-trials were performed with Cabernet sauvignon sort; in some variants time and temperature of maceration were varied, while the ratio of residual stem and content of seed was increased several times, resulting in a significant change of phenolic compounds content in the obtained wine samples. The presence of ripe stem yielded good results, but only during six days of maceration, while in the case of longer maceration, the change of colour quality was negative. Supplementary quantities of seeds during maceration resulted in an increase of total phenols and catechins. A significant influence on colour of wines was also observed, especially in wines obtained applying shorter maceration.
The economic analysis of lone wolf terrorism

Abstract Purpose This chapter explains how economic analysis can contribute to the delineation of the lone wolf’s opportunities and choices in a manner that allows operationally relevant advice to be contributed to the investigative process. Approach Using a risk-reward analytical framework we examine the lone wolf’s attack method opportunities and choices and identify those attack methods that would be chosen by lone wolves with different levels of risk aversion. We also use prospect theory as an alternative methodology for the determination of the lone wolf’s preference orderings over the available attack methods in a context where he references his actions against those of a predecessor whom he wishes to emulate. Findings We find that lone wolf terrorists with different levels of risk aversion can be expected to choose different attack methods or combinations of attack methods. More risk averse lone wolf terrorists will choose attack methods such as assassination. Less risk averse lone wolf terrorists will choose attack methods such as bombing, hostage-taking and unconventional attacks. Also, we find that lone wolf terrorists who reference their actions against ‘predecessor’ lone wolf terrorists will choose differently from among the available attack methods depending on which predecessor lone wolf is being referenced. Limitations The analysis provides two different perspectives on terrorist choice but by no means exhausts the analytical alternatives. The analysis focuses on the fatalities and injuries inflicted whereas other perspectives might include different ‘payoffs’ series, including news or media coverage. Originality The chapter contributes an analysis of the order in which lone wolf terrorists with particular characteristics will choose from a set of available attack methods. During the course of our discussion we point out the consistency between the ‘rise’ of the lone wolf terrorist and the diseconomies to scale that are evident within the terrorism context. This presents the opportunity for new debates.
Context and Political Knowledge: Explaining Cross-National Variation in Partisan Left-Right Knowledge

We present a theory that links variation in aggregate levels of political knowledge across countries and over time to corresponding differences in the political context in which voters become (or do not become) informed. Specifically, we argue that the level of partisan left-right knowledge in a given context ultimately depends on how useful the left-right metaphor is for organizing, simplifying, or otherwise facilitating voters’ understanding of political processes. Using survey data on the distribution of left-right knowledge in 59 different contexts (in 18 countries), our analysis reveals that voters understand the relative left-right positioning of parties to a much greater degree when these positions are important predictors of the composition of policy-making coalitions, but that variation in this knowledge does not correspond to the accuracy with which the relative left-right positions of parties predicts more narrow policy positions.
The Association Between Emotional Intelligence and Suicidal Behavior: A Systematic Review

Background: Some meta-analyses have demonstrated the association between emotional intelligence (EI) and different health indicators. With the increase of suicide cases in the world, more and more professionals have been interested in the link between both variables. Aim: To study all the available evidence on the association between EI and suicidal behavior. Method: We systematically reviewed all available literature (in English or Spanish) on the relationship between both variables through the main databases. Results: Twenty-five articles were included. EI and suicidal behavior correlated inversely in almost all the articles that the Emotional Quotient Inventory (EQ-i), The Emotional Intelligence Test (EIT), The Spanish Wong and Law Emotional Intelligence Scale (WLEIS), and The Schutte Emotional Intelligence Scale (EIS/SSEIT), Barchard's Emotional Intelligence Scale, were used, that is, the higher suicidal behavior level the lower the EI score. The same results were found in two out of four investigations that used the Trait Meta-Mood Scale (TMMS-24) between clarity (emotional understanding) and emotional repair (emotional regulation) and suicidal behavior. Two out of three studies that used the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) found that only the Strategic component of EI (emotional understanding and regulation) was a protective factor. Conclusions: The results appear to indicate that a high level of EI plays an important role in protecting against suicidal behavior, and should thus be integrated into suicide prevention programs.
Institutional Corporate Social Responsibility (CSR) Practices: The Influence of Leadership Styles and Their Perceived Ethics and Social Responsibility Role

This paper investigates leader’s perceptions of ethics and social responsibility (PRESOR) on organisation’s institutional CSR practices. The results indicate that while the managers in this study perceive that ethics and social responsibility play an important role in determining the organisation’s long-term and short-term gains, they do not think that ethics and social responsibility are the only important factors in determining firm’s profitability and survival, as indicated by the non-significant results of the PRESOR (social responsibility and profitability) dimension. Another objective was to determine the types of leadership style in influencing the adoption and practices of CSR. As oppose to many previous studies, the results indicate that among the leadership styles, transactional leadership influences institutional CSR practices, while transformational leadership does not. This finding implies that for CSR practices to be implemented, leaders need to use rewards, rules and regulations in a Malaysian context. In other words, in order to institutionalise CSR practices in Malaysia, corporations should start by introducing extrinsic incentives.
A Multivariate Garch Model with Volatility Spill-Over and Time-Varying Correlations

There is now a wide array of GARCH models available that are able to capture many important features of a univariate return time series. However, a lot of questions still remain open about which models are suitable for capturing the dynamics of multivariate return time series. This paper introduces a model for asset returns that incorporates joint heteroscedasticity as well as time varying correlations. It nests the model with cross-sectional volatility by Hwang and Satchell (2005) as well as the dynamical conditional correlation framework by Engle (1999). We t the model to ten years of data for stocks in the Dow Jones Industrial Average. The empirical results suggest that the average pairwise correlation behaves strongly countercyclical. This means that the benets of diversication go down exactly when they are most desirable, which might serve as an explanation why the volatility smile in index options tends to be more pronounced than in individual stocks options.
General Output Feedback Stabilization for Fractional Order Systems: An LMI Approach

This paper is concerned with the problem of general output feedback stabilization for fractional order linear time-invariant (FO-LTI) systems with the fractional commensurate order . The objective is to design suitable output feedback controllers that guarantee the stability of the resulting closed-loop systems. Based on the slack variable method and our previous stability criteria, some new results in the form of linear matrix inequality (LMI) are developed to the static and dynamic output feedback controllers synthesis for the FO-LTI system with . Furthermore, the results are extended to stabilize the FO-LTI systems with . Finally, robust output feedback control is discussed. Numerical examples are given to illustrate the effectiveness of the proposed design methods.
Producing value from Australia's vineyards: an ethnographic approach to 'the quality turn' in the Australian wine industry

Abstract This article provides a detailed ethnographic intervention to the phenomenon of value-added agriculture, a discourse that has attained several concrete forms in Australian wine industry policy, and which is routinely presented as a legitimate rural future in wider agricultural and social science research. The legal and policy architecture of 'Geographical Indications' purports to value the regional distinctiveness of agricultural areas, by creating legally-defined wine regions. Producers from these wine regions enjoy privileged access to the use of regional descriptors that apply to their products, and the constitution of such wine regions can also codify the relationships between this regional identity and concrete viticultural and winemaking practices. This article draws on ethnographic research within the Clare Valley region of South Australia, one of the first Australian wine regions to be formally constituted as a legal entity, to examine in close detail the relationships that this region's wine producers have with their own discrete areas of operation. These ethnographic illustrations highlight that the creation of economic value within the premium wine industry cannot be reduced to the technical aspects of viticulture and oenology, nor the legal and policy means by which relationships between products and land are codified. Rather, the nuanced social understandings of landscape that wine producers are consistently developing is a critical element of cultural and commercial infrastructure that affords any wine producer or grape grower the possibility of achieving monopolistic relationships over discrete vineyard areas and the wine that is produced from them. These social understandings have a specifically egalitarian character that acts as a hedge against the chronic uncertainties arising from the global economic environment in which premium wine industry is inescapably a part. This resistance to codification, I argue, is a productive space that constitutes a form of resilience against chronically unstable sets of commercial and environmental conditions.

Comparison of in situ nutrient disappearance of alternative maize milling by-product feeds in lactating dairy cows

Two maize milling by-products (maize gluten feed; MGF and maize by-product feed; MBPF) were compared with shelled maize (SM) and soyabean meal (SBM) for their in situ nutrient disappearance. In situ experiments were conducted in two rumen fistulated Holstein cows to evaluate dry matter (DM), crude protein (CP), neutral detergent fibre (NDF) and starch disappearance of the products. Zero-hour washout (in situ Fraction A) of DM was higher for MBPF (56.9%) than SM (45.0%). The disappearing rate (kd) of DM was higher for MGF (0.054/h) than for SM (0.046/h). Fraction A for CP was higher for MBPF (69.6%) than MGF (55.9%) and lower for SBM (7.8%). Similarly, ruminal CP disappearance was higher for MBPF (83.4%) and MGF (80.1%) than SBM (52.1%). Neither NDF disappearance rate nor ruminal NDF disappearance was different between MGF and MBPF. The disappearance rate of starch was higher for MGF (0.203/h) and MBPF (0.116/h) than for SM (0.051/h). Similarly, ruminal starch disappearance was higher for MGF (82.7%) than for SM (54.2%). Results indicate that the tested maize by-product feeds had greater ruminal CP disappearance when compared to SBM. Both MGF and MBPF may be useful feedstuffs in lactating dairy cows ration due to their higher ruminal starch disappearances. South African Journal of Animal Science Vol. 36(1) 2006: 7-12
Nucleon axial form factors using $N_f$ = 2 twisted mass fermions with a physical value of the pion mass

We present results on the nucleon axial and induced pseudo-scalar form factors using an ensemble of two degenerate twisted mass clover-improved fermions generated at the physical value of the pion mass. We evaluate the isovector and the isoscalar, as well as, the strange and the charm axial form factors. The disconnected contributions are evaluated using recently developed methods that include deflation of the lower eigenstates, allowing us to extract the isoscalar, strange and charm axial form factors. We find that the disconnected quark loop contributions are non-zero and particularly large for the induced pseudo-scalar form factor.
Patterns of productivity during eutrophication: a mesocosm experiment

In a 28 mo mesocosm experiment , levels and patterns of productivity and respiration were observed for a range of nutrient additions selected to provide a gradation from conditions in lower Narragansett Bay, Rhode Island , USA. to maximum impact for an urbalJ. t\! ary receiving present day leve1s of sewage effluents. For a 3Z. fold increase in nutrients, system apparent prod.uction increased by only a factor of 3,5. Seasonal patterns of . autotrophy during the winter-spring diatom bloom and , heterolrophy during summer and early fall occurred at all treatment levels. With the exception of the 8 x treci\ment, all treatments above 2 X had a greater respiratory demand in the water column than the benthos. The highest treatment mesocosm (32 X) wentbrieny anoxic during the second summer of the experiment during a period when little productivity was occurring in the water column.
