The Pricing of Government-Guaranteed Bank Bonds

We examine the effects of the government guarantee schemes for bank bonds adopted in the aftermath of the Lehman Brothers demise to help banks retain access to wholesale funding. We describe the evolution and the pattern of bond issuance across countries to assess the effect of the schemes. Then we propose an econometric analysis of one striking feature of this new market, namely the significant i? ½tieringi? ½ of the spreads paid by banks at issuance, finding that they mainly reflect the characteristics of the guarantor (credit risk, size of rescue measures, timeliness of repayments) and not those of the issuing bank or of the bond itself.

Ectomycorrhizal fungi associated with Arctostaphylos contribute to Pseudotsuga menziesii establishment

Chaparral on the central coast of California can occur as relatively stable patches of ectomycorrhizal Arctostaphylos directly adjacent to arbuscular mycorrhizal Adenostoma. Vegetation surveys and seedling survival assays show that Pseudotsuga establishes only in Arctostaphylos. We found no significant differences between Arctostaphylos and Adenostoma in allelopathy; light; temperature; or soil NH 4 + ,N O 3 - ,o r K.Arctostaphylos soils tended to be higher in phosphate and were lower in pH, Ca, Mg, Ni, and Cr than those from Adenostoma. After 1 year of growth of Pseudotsuga seedlings in an Arctostaphylos patch, 17 species of fungi colonized both Pseudotsuga and Arctostaphylos. Fifty-six of 66 seedlings were colonized by fungi that also colonized Arctostaphylos within the same soil core. Forty- nine percent of the Pseudotsuga ectomycorrhizal biomass was colonized by fungi that were also associated with Arctostaphylos within the same core. Another 12% was colonized by fungi known to associate with Arctostaphylos from different cores. After 4 months of growth, Pseudotsuga seedlings in four of five Arctostaphylos plots were ectomycorrhizal and colonized by fungi in Russulaceae, Thelephoraceae, and Amanitaceae. Pseudotsuga seedlings in two of five Adenostoma plots were ectomycorrhizal but colonized by only two species of fungi in Thelephoraceae. These results provide compelling evidence that ectomycorrhizal fungi associated with Arctostaphylos contribute to Pseudotsuga seedling establishment.
Embedded system for regulating abiotic parameters for Capsicum cultivation in a polyhouse with comparison to open-field cultivation

ABSTRACT Polyhouse cultivation enables year-round production of bell pepper (Capsicum annuum L.). Maintaining a favorable micro-climate inside a polyhouse is mostly through manual operation of environmental control systems in developing countries, and to varying degrees, with automation in developed countries. In this study automation of micro-climate control through sensors and controllers was examined. Soil moisture, relative humidity, and air temperature sensors were installed at different locations inside a polyhouse for the operation of irrigation, foggers, and fan-pad cooling systems. Threshold values of these parameterswere set as input to the programmable logic controller and systems. Bell pepper is an economically important crop rich in nutrients. The efficacy of the use of an automated system to control the growing environment for this crop needs to be clarified. The experiment was conducted using cv. Swarna, grown under open-field and polyhouse culture, at irrigation levels of 80% or 100% of crop evapotranspiration. Type of growing environment affected yield and fruit size, with production in the polyhouse being better, but irrigation level did not. The programmable logic controller-based automation system worked well for micro-climate control leading to 93% and 53% higher yield and fruit weight, respectively, in the polyhouse than open-field cultivation. The programmable logic controller-based automation can aid in maintaining a favorable microclimate inside a greenhouse leading to better bell pepper yield.
THE STUDY ON RELATIONSHIP BETWEEN EMOTIONAL AND EMPLYOEES' CREATIVITY OF SOCIAL SECURITY ORGANIZATION IN TUSERKAN, NAHAVAND AND ASADABAD IN IRAN

In This study tried to investigate the relationship between and employees’ emotional intelligence and their creativity. In other word it is answered to this question: Is there a significant and positive correlation between employees’ emotional intelligence and their creativity or not? In regard to for hiring creative human resource, it is more attention to their rational intelligence and responsibilities do not attention to other side of intelligence, special emotional intelligence. Therefore it has been tried to assess the correlation between employees’ emotional intelligence and their creativity in the research. Statistical population of this research includes 65 employees of the social security organization in Toyserkan, Nahavand and Asasabad cities. 56 employees were selected by using Morgan Table. Sampling was conducted randomly. Tow questionnaires were used for collecting data: creativity and emotional intelligence questionnaire. Validity of tow questionnaires was approved by management professors. For determining reliability of questionnaires, it was used from Cronbach's alpha. Coefficient alpha of emotional intelligence and creativity questionnaire were equal to . 810 and . 940 respectively for creativity and emotional intelligence. Descriptive statistics, such as frequency, percentage, mean and graphs were used. In inferential statistics section, linear regression was used to determine the relationship between the variables of emotional intelligence and employees’ creativity. Results from the survey shows that there is a positive and significant relation between all dimensions of emotional intelligence and creativity.
Landscape Patterns Associated with Occupancy of Disturbance-Dependent Birds in the Blackland Prairie Ecoregion of Alabama and Mississippi

Abstract The Blackland Prairie Ecoregion of Alabama and Mississippi, formerly a mosaic of prairie, shrubland, and forest, has undergone massive landcover change in the past 2 centuries. Even though the region is now dominated by agriculture and ranchland, disturbance-dependent birds—a guild in decline—continue to inhabit the Blackland Prairie Ecoregion. Therefore, we investigated the relationship between landscape patterns at 4 spatial scales (within 200 m, 600 m, 1000 m, and 3000 m of survey points) and occupancy for 17 species of disturbance-dependent birds. We used a Bayesian occupancy model to relate avian detections to landcover covariates and used stochastic search variable selection to identify covariates that were relevant to occupancy for each species. The amount of canopy cover was the covariate most frequently identified as relevant to occupancy. Grassland and open-country species showed a negative relationship with canopy cover, while shrubland species showed a positive relationship with canopy cover. The association between occupancy and covariates was strongest at the smaller spatial scales, though covariates at the larger spatial scales were still selected as relevant to occupancy. Our results highlight the importance for land managers to consider the landscape context prior to making on-the-ground conservation action; measures aimed to conserve grasslands, for example, will likely be ineffective if they take place in landscapes with high canopy cover.
Chemotaxis and topotaxis add vectorially for amoeboid cell migration

Cells encounter a wide variety of physical and chemical cues when navigating their native environments. However, their response to multiple simultaneous cues is not yet clear. In particular, the influence of topography, in the presence of a chemotactic gradient, on their migratory behavior is understudied. Here, we investigate the effects of topographical guidance on highly motile amoeboid cell migration (topotaxis) generated by asymmetrically placed micropillars. The micropillar field allows for an additional, natural chemotactic gradient in two different directions, thereby revealing the relevance of topotaxis in the presence of cell migration directed by chemical gradients (chemotaxis). Interestingly, we found that the topotactic drift generated by the pillar field is conserved during chemotaxis. We show that the drifts generated by both these cues add up linearly. A coarse-grained analysis as a function of pillar spacing subsequently revealed that the strength and direction of the topotactic drift is determined by (i) the pore size, (ii) space between pores, and (iii) the effective diffusion constant of the cells. Finally, we argue that topotaxis must be conserved during chemotaxis, as it is an emergent property of both the asymmetric properties of the pillar field and the inherent stochasticity of (biased) amoeboid migration.
Statistics of the Jacobians of hyperelliptic curves over finite fields

Let $C$ be a smooth projective curve of genus $g \ge 1$ over a finite field $\F$ of cardinality $q$. In this paper, we first study $\#\J_C$, the size of the Jacobian of $C$ over $\F$ in case that $\F(C)/\F(X)$ is a geometric Galois extension. This improves results of Shparlinski \cite{shp}. Then we study fluctuations of the quantity $\log \#\J_C-g \log q$ as the curve $C$ varies over a large family of hyperelliptic curves of genus $g$. For fixed genus and growing $q$, Katz and Sarnak showed that $\sqrt{q}\left(\log \# \J_C-g \log q\right)$ is distributed as the trace of a random $2g \times 2g$ unitary symplectic matrix. When the finite field is fixed and the genus grows, we find the limiting distribution of $\log \#\J_C-g \log q$ in terms of the characteristic function. When both the genus and the finite field grow, we find that $\sqrt{q}\left(\log \# \J_C-g \log q\right)$ has a standard Gaussian distribution.
Di usion regimes in L evy ights with trapping

The di usion of a walk in the presence of traps is investigated. Di erent di usion regimes are obtained considering the magnitude of the uctuations in waiting times and jump distances. A constant velocity during the jump motion is assumed to avoid the divergence of the mean squared displacement. Using the limit theorems of the theory of L evy stable distributions we have provided a characterization of the di erent di usion regimes. c © 1999 Elsevier Science B.V. All rights reserved.

PROFITABILITY OF CONSTRUCTING SECTOR AND HOW MARKET STRUCTURE, COST STRUCTURE AND CONCENTRATION AFFECT IT: THE CASE OF GREECE

This study considers market structure, cost structure and concentration and examines which of these factors affect the profitability of construction firms in Greece. The literature provides conflicting viewpoints on whether profitability is influenced by market structure, cost or capital structure or concentration and in what way. Concentration is considered as a factor that can either boost/reduce or even have weak or inexistent correlation with profitability (Kapopoulos and Siokis, 2002). As regards the market share, it is thought as being positively correlated with profitability (Kapopoulos and Siokis, 2002). However, other scholars (Fraering and Minor, 1994; Ailawadi et al., 1999), support that market share does not have significant impact on profitability. Statistical results showed that market structure and concentration seem not to have an impact on profitability. On the contrary, the cost structure, as well as the capital structure, influences the profitability of construction firms. Return on Equity (ROE) has negative correlation with Cost of Goods Sold (COGS) and positive correlation with book value to total assets (BVTA). The correlation with market share is positive, but rather weak. The regression analysis also shows the relationships of COGS and total liabilities to total assets (TLTA) on ROE. As observed, market share, concentration and liquidity do not impact ROE.
Torque Teno Virus and Hepatitis: A review on correlation.

Torque teno virus (TTV) is one of the “orphan” virus that have been discovered almost two decades ago, with little information on the relationship of the infection to any diseases. It is one of the 45% of commensal virus which was found throughout the population and becoming one of the most extensively studied viruses on its prevalence among various level of health status. From healthy blood donors to patients who suffered severe illness, TTV infection level seems to be high and the findings has triggered an interest from the researcher. Even though the study on TTV prevalence is actively performed, the actual pathogenesis of TTV to any specific diseases is yet to be ascertained. Many suggestions on the possible association of TTV infection with severe diseases such as acute respiratory diseases, liver-related diseases and even cancer have been discussed. However, one type of diseases which might have an association with TTV is hepatitis. Albeit, it remains a theory as the actual pathogenicity of TTV is not fully understood.
Dynamic Modeling and Simulation of Compressor Trains for an Air Separation Unit

Abstract This paper presents dynamic models of a compressor train for an air separation unit. The model is derived from physical equations. A block library and complete models are implemented in Matlab/Simulink. Model accuracy is validated by comparing simulation results with realistic data gained from an existing industrial plant. The goal of modeling is to obtain a better understanding of the dynamic behavior in different operating modes and to get a base for design of new control strategies, e.g. a supervisory controller for minimizing power consumption of the total compressor train.
Regulation and Investment in Next Generation Access Networks: Recent Evidence from the European Member States

Fibre-deployment of future telecommunications networks (“Next Generation Access” - NGA) is a major challenge for sector-specific regulators as well as for investing firms. Although the future socioeconomic importance of new telecommunications networks is uncontroversial, the related investment activities vary substantially in international comparison. This work identifies the most important determinants of NGA deployment, using data from the EU27 member states for the years 2005 to 2010. Our results indicate that stricter previous broadband access regulation has a negative impact on NGA deployment, while competitive pressure from broadband and mobile affects NGA deployment in an inverted U-shaped manner. We further find that there are severe adjustment costs and stickiness towards the desired long-term level of NGA infrastructure. It appears that the approach of the European Commission of strict cost-based access regulation will not elicit the huge new investment needed for a comprehensive NGA roll-out.
Elasticity and Topography-Controlled Collagen Hydrogels Mimicking Native Cellular Milieus

Accumulating evidence demonstrates that the elasticity and topography of a cell culture substrate influence cell behavior, in addition to its chemical composition. However, cellular responses to in vivo extracellular matrix (ECM), a hydrogel of proteins (mainly collagen) with various elasticity and a nanometer-to micrometer-scale topography, remain to be elucidated owing to a lack of substrate that provides such complex cues. This study introduces novel collagen hydrogels that can combine, for the first time, elastic, topographic, and compositional cues that recapitulate native ECM. A simple and reagent-free method based on radiation crosslinking alters ECM-derived collagen solutions into hydrogels with a well-defined and tunable elastic modulus covering the broad range of soft tissues (1–236 kPa) and microtopographies while ensuring intrinsic biological functionality of collagen. These collagen hydrogels enabled investigating cell responses to soft topographic cues such as those encountered in vivo, revealing that topography overrides the elasticity and structurally constrains cell morphology by controlling actin cytoskeleton organization. The collagen hydrogels not only reduce in vivo and in vitro behavioral disparity of cells by mimicking native ECM but also facilitate the design of artificial ECM to control cell function and fate in tissue engineering and regenerative medicine.
Seasonal change in environmental DNA concentration of a submerged aquatic plant species

Environmental DNA (eDNA) methods are increasingly used to detect aquatic organisms. To optimize survey efficiency in natural environments, it is necessary to understand the seasonal change in eDNA concentrations of target species and identify the season and environmental conditions in which eDNA concentrations are highest. Recently, eDNA methods have been developed to detect aquatic plant species, but the seasonal change in the eDNA concentrations remains uninvestigated. Many aquatic plants undergo considerable changes in abundance, size, and shape throughout the year. Therefore, their eDNA concentration may change along with their phenology. We investigated the seasonal change in the eDNA concentration of an aquatic submerged species, Hydrilla verticillata, in agricultural ponds in Japan by measuring the eDNA concentration of H. verticillata from 5 ponds 5× in a year. This species has a dormant period during winter and a growth period from spring to autumn. The eDNA concentrations were higher during the growth period than during the dormant period. Management and conservation surveys that use eDNA for species detection should be done when eDNA concentrations are highest to maximize detection probabilities and therefore survey efficiency.
Management Strategies for POSEIDON Groups 3 and 4

In the POSEIDON classification, patients belonging to groups 3 and 4 share the same common feature of a poor ovarian reserve which independently of age renders them at high risk of a poor reproductive outcome. Overall, POSEIDON groups 1–4 constitute approximately 47% of patients attending assisted reproductive technology (ART) treatment. With the increasing delay in childbearing, POSEIDON group 4 seems to increase in numbers now in some centers constituting more than 50% of the total POSEIDON population, whereas group 3 patients constitute approximately 10%. Both POSEIDON groups 3 and 4 patients require special attention as regards pre-treatment strategy, ovarian stimulation, adjuvant treatment, and ovulation trigger strategy in order to optimize the probability of having at least one euploid blastocyst for transfer. Although more evidence is needed, recent advances seem to have increased the reproductive outcomes in the poor prognosis patient. The key to success is individualization in all steps of ART treatment. Herein, we review the recent evidence for the management of POSEIDON groups 3 and 4.
Unusual corrections to scaling in entanglement entropy

We present a general theory of the corrections to the asymptotic behaviour of the Rényi entropies SA(n) = (1 − n) − 1logTrρAn which measure the entanglement of an interval A of length with the rest of an infinite one-dimensional system, in the case when this is described by a conformal field theory of central charge c. These can be due to bulk irrelevant operators of scaling dimension x > 2, in which case the leading corrections are of the expected form for values of n close to 1. However, for n > x/(x − 2) corrections of the form and arise and dominate the conventional terms. We also point out that the last type of corrections can also occur with x less than 2. They arise from relevant operators induced by the conical spacetime singularities necessary to describe the reduced density matrix. These agree with recent analytic and numerical results for quantum spin chains. We also compute the effect of marginally irrelevant bulk operators, which give a correction , with a universal amplitude. We present analogous results for the case when the interval lies at the end of a semi-infinite system.
Knowledge transfer within strategic partnerships: the case of HRM in the Brazilian motor industry supply chain

This paper investigates knowledge transfer (KT) of human resource management (HRM) across strategic partnerships in the Brazilian automotive industry, and the contextual factors impacting on KT within the supply chain. Case-study research in automotive companies and suppliers in Brazil is used to illustrate how in automotive industries, relationships with suppliers have traditionally been viewed as close, strategic partnerships, but over time, there has been a move towards more attenuated, supply chains, involving a shift towards more remote suppliers for basic components, and arms length relationships with them. In turn, this has impacted on how knowledge on HR has been transferred from manufacturers to suppliers. Both strategic partnerships and KT have been affected by internal drives towards cost cutting and talent retention, and external factors such as global competition through cheap imports, legislation, taxes, and unions. Evidence on the sometimes contradictory attitudes towards KT contributes towards the broader literatures on international HRM and KT in emerging economies, while the gradual unwinding of relationships has implications for policy and practice.
