DRIVERS AND PERFORMANCE OUTCOMES OF RESPONSIBLE CARE: THE CASE OF LITHUANIAN CHEMICAL INDUSTRY

The paper looks into different motives that drive organisation managers to engage into the activities of corporate social responsibility, and seeks to determine organisational outcomes of such policies and practices. Specific focus is given to the CSR policies and practices in the chemical industry, which suffers an extremely low public opinion in respect to environmental safety. The paper also looks into the industry’s self regulation attempts and looks into Responsible Care, an initiative of the chemical industry organisations to act responsibly, which is the world’s leading voluntary industry initiative, and its situation among chemical industry organisations in Lithuania. Research findings show that currently only a third of Lithuanian organisations belonging to the chemical industry association support the initiative, while the main motive for engaging into it activities is corporate image enhancement.
Molecular Diversity Assessment in Chickpea through RAPD and ISSR Markers

Chickpea (Cicer arietinum L.) is a cool season food legume in the family of Fabaceae. The exploration of genetically variable accessions is the key source of germplasm conservation for future selecting parents for breeding. PCR based analysis employing RAPD and ISSR marker are one of the established techniques of estimation of genetic diversity. Twelve chickpea accessions were analyzed by ten RAPD and ISSR primers of which all primers gave amplification products. The results showed that the level of DNA polymorphism in these accessions is low. RAPD analysis yielded 5.9 bands per primer while ISSR analysis produce 2.8 bands per primer. The average percentage of molecular polymorphism as produced by RAPD and ISSR primers was 67%. The cluster dendrogram demonstrated a similarity coefficient range of 0.10 to 0.66 due to RAPD markers, whereas ISSR markers showed 0.60 to 0.80. The variability index worked out in the present study ranges from 0.49 to 0.78. The present study determines DNA polymorphism in chickpea accessions as revealed by RAPD and ISSR markers. Overall the study ascertained that RAPD and ISSR marker provide powerful tools in revealing genetic diversity in chickpea.
CFD Simulation of Cloud and Tip Vortex Cavitation on Hydrofoils

The onset of cavitation around propellers, hydrofoils, ships, etc represents an important issue in terms of reduced performance, erosion and passenger/crew comfort due to cavitation induced vibrations and noise among other drawbacks. Consequently cavitation has been studied by many researchers, but up to now most of the investigations are still experiments. Since experimental investigations for marine applications are expensive, CFD simulations represent a powerful tool in order to investigate the phenomenon and consequently to improve the design of such components. A model to deal with cavitation and the pressure fluctuations introduced by it has been developed in ANSYS CFX, and a validation of it has been carried out. Two test cases have been chosen for this purpose. The first one is a 2D case containing a plano-convex profile, where cloud cavitation can be observed. The second one consists of a 3D case, where the fluid flows around a NACA 66 2-415 hydrofoil. A tip vortex is generated with high radial velocity gradients originating cavitation. In both cases the simulations have been carried out on refined grids and the numerical results have been compared to those in literature, showing good agreement with them in most of the cases.
Patrón de Uso y Dependencia de Videojuegos en Infancia y Adolescencia

Video games are one of the most attractive forms of leisure. Today it is one of the main activities of children and adolescents, because of the interest they have for them and the time the adolescents spend in playing. Despite the undoubted benefits of this activity, in some cases the excessive use leads to abuse and other causes serious personal and family problems. This paper has two objectives. First, analyze the pattern of use of video games, focusing on gender differences. Second, the development of a questionnaire of video games dependence, according to the criteria of DSM-IV Disorders Substance Abuse and adapting to the use of video games. The factorial structure of this questionnaire is consistent with the concept of dependence, as defined in DSM-IV. Along with Internet and mobile, video game dependency would be one of the most characteristic technological addictions.
Relationships between diurnal xylem diameter variation and environmental factors in Scots pine

We analyzed the variability in diurnal xylem diameter in Scots pine (Pinus sylvestris) by comparing daily maximum, minimum and average diameters and daily amplitudes of variation with environmental variables related to transpiration and water uptake from the soil. The measurements were carried out during six summers, 1999-2004 at SMEAR II station in Hyytiala, southern Finland. We found that the daily maximum, minimum and average diameters and amplitudes were closest related to daily average water vapor deficits (VPD) and soil water contents in A-horizon (θ A ). However, the highest degree of determination was only 37%. That was found for daily minimum diameter by VPD. The degree of determination and correlation could be improved by making up variables that took into account the variation in factors related to transpiration and soil water availability. In that case the highest correlation (negative correlation) and coefficient of determination was found for daily minimum diameter by VPD scaled with θ A so that VPD was enhanced when soil water content was low (VPD* = VPD*(θ Amin /θ A )). This could explain 50% of the variation in daily minimum diameters. The results emphasize the importance of both inflow- and outflow-related factors in explaining the water tension and water status of tree stems.
ESTIMATES OF TRUE AMINO ACID DIGESTIBILITIES IN FEED INGREDIENTS USING PRECISION-FED , CECECTOMIZED ROOSTERS 1

Twenty seven cecectomized mature Single Comb White Leghorn cockerels were used to estimate true amino acid digestibilities (TAAD) coefficients for eight feedstuffs for cecectomized roosters. The objective of this paper was to evaluate alternative feed ingredients TAAD coefficients using a standard precision fed (crop-intubation) methodology. The ingredients tested were corn, wheat bran (WB), two sources of soybean meal (SBM 1 and SBM 2), cottonseed meal (CSM), poultry by-product (PBP), and two samples of meat and bone meal (MBM 1 and MBM 2). A group of three roosters was fasted 24 hours prior to each assay to allow measurement of endogenous amino acid production. True lysine digestibility (TLD) in CSM (71.8%) was significantly lower (P<.01) than in all the other feed sources. No differences (P>.01) were found for TLD among the other ingredients. Means and standard error of means for TAAD were: corn 103.03±4.30, WB 90.35±2.26, SBM 1 93.13±1.55, SBM 2 92.99±2.39, CSM 81.16±4.67, PBP 86.23±2.14, MBM 1 86.20±2.49, MBM 2 85.98±2.26. In general the averages of the coefficients for TAAD of the ingredients used are in the range of the values reported in the literature and can be used to formulate diets based on amino acid digestibility.
The Effects of Dietary Garlic Powder on the Performance, Egg Traits and Blood Serum Cholesterol of Laying Quails

This study was conducted to study the effects of dietary garlic powder on laying performance, egg traits and blood serum cholesterol level of quails. A total of three hundred quails (Coturnix coturnix japonica) aged nine weeks were used. They were allocated to 3 dietary treatments. Each treatment comprised 5 replicates of 20 quails. The diets were supplemented with 0, 5 and 10 g/kg garlic powder. The experimental period lasted 21 weeks. The addition of garlic powder did not significantly affect body weight, egg production, feed consumption, feed efficiency, egg shell thickness, egg albumen index, egg yolk index and egg Haugh unit. Adding 5 and 10 g/kg garlic powder to the laying quail diets increased egg weight (p<0.01). Egg yolk cholesterol and blood serum cholesterol concentration were reduced with garlic powder supplementation. The results of this study demonstrated that garlic powder addition had a significant cholesterol-reducing effect in serum and egg yolk without adverse effects on performance and egg traits of laying quails.
Productivity Growth and Efficiency Change in Electricity Distribution

The decade since privatisation of the UK electricity industry provides an important sample over which to measure productivity growth and efficiency change in electricity distribution. The core idea of incentive based RPIX regulation is to stimulate productivity growth and the convergence of efficiency change amongst the distribution companies. The X factor may represent the regulator’s estimate of the potential for productivity growth, and may also be an instrument for yardstick regulation of these regional distribution monopolies. The expectations generated by the privatisation programme are of large increases in productivity.
An onto-semiotic approach to representations in mathematics education

Research in didactics of mathematics has shown the importance that representations have in teaching and learning processes as well as the complexity of factors related to them. Particularly, one of the central open questions that the use of representations poses is the nature and diversity of objects that carry out the role of representation and of the objects represented. The objective of this article is to show how the notion of semiotic function and mathematics ontology elaborated by the ontosemiotic approach to mathematics knowledge, enables us to face such a problem, by generalizing the notion of representation and by integrating different theoretical notions used to describe mathematics cognition.
Research on Frozen Soil Structure Influence over Transformer DC Magnetic Biasing in UHVDC Transmission

This study studies the exciting current of transformer affected by DC bias in the Tibet frozen soil structure when the UHVDC system is working in monopole state. Firstly, the model of calculating the ground potential for a typical frozen soil of the Tuotuo River substation was described and then the ground potential around the UHVDC grounding electrode for five-layer soil in summer and winter was calculated. According to the soil parameters, the magnetic bias current of the transformer were calculated. Results indicate that the distance is less than about 4 km and the earth potential is variable in different season. The substation electrode design parameters are complex, so building substation is very inconvenient. And when the distance is adjusted from 4 km to 8km, the earth potential is changed from 400 to 200 V, the exciting current decreased from 45 to 5 mA, the waveform unbalance will also decrease.
A CHARACTERISATION OF WIGNER YANASE SKEW INFORMATION AMONG STATISTICALLY MONOTONE METRICS

Let be the space of n × n complex matrices endowed with the Hilbert–Schmidt scalar product, let Sn be the unit sphere of Mn and let Dn⊂ Mn be the space of strictly positive density matrices. We show that the scalar product over Dn introduced by Gibilisco and Isola3 (that is the scalar product induced by the map ) coincides with the Wigner–Yanase monotone metric.
Ratio and Difference of l 1 and l 2 Norms and Sparse Representation with Coherent Dictionaries

The ratio of l 1 and l 2 norms has been used empirically to enforce sparsity of scale invariant solutions in nonconvex blind source separation problems such as nonnegative matrix factorization and blind deblurring. In this paper, we study the mathematical theory of the sparsity promoting properties of the ratio metric in the context of basis pursuit via over-complete dictionaries. Due to the coherence in the dictionary elements, convex relaxations such as l 1 minimization or non-negative least squares may not ﬁnd the sparsest solutions. We found sufﬁcient conditions on the nonnegative solutions of the basis pursuit problem so that the sparsest solutions can be recovered exactly by minimizing the nonconvex ratio penalty. Similar results hold for the difference of l 1 and l 2 norms. In the unconstrained form of the basis pursuit problem, these penalties are robust and help select sparse if not the sparsest solutions. We give analytical and numerical examples and introduce sequentially convex algorithms to illustrate how the ratio and difference penalties are computed to produce both stable and sparse solutions.
Underpricing and underwriter wealth gains

The paper examines a subset of IPOs that have publicly traded underwriters and finds that these underwriters have positive abnormal stock price increases of 0.23% around the IPO prospectus filing date and 0.21% around the issue date for an average market capitalization increase of $64 million and $59 million, respectively. The paper investigates the potential sources of these underwriter wealth gains: the underwriter spread for the offering, enhanced reputation due to successful IPOs, and wealth transfers from IPO firms to underwriters. The author finds that underwriter wealth gains are concentrated on IPO offerings with the highest underpricing, consistent with wealth transfer from the IPO firm. Further, underwriters with the most ability to transfer wealth have the strongest relationship between underwriter wealth gains and underpricing. Finally, the article shows that the operating performance of the underwriter is related to the aggregated underpricing of new stock issues. On average, for every dollar of underpricing, the underwriter has a stock price increase of $0.45 and an annual sales increase of $0.16.
Numerical wave interaction with tetrapods breakwater

ABSTRACT The paper provides some results of a new procedure to analyze the hydrodynamic aspects of the interactions between maritime emerged breakwaters and waves by integrating CAD and CFD. The structure is modeled in the numerical domain by overlapping individual three-dimensional elements (Tetrapods), very much like the real world or physical laboratory testing. Flow of the fluid within the interstices among concrete blocks is evaluated by integrating the RANS equations. The aim is to investigate the reliability of this approach as a design tool. Therefore, for the results' validation, the numerical run-up and reflection effects on virtual breakwater were compared with some empirical formulae and some similar laboratory tests. Here are presented the results of a first simple validation procedure. The validation shows that, at present, this innovative approach can be used in the breakwater design phase for comparison between several design solutions with a significant minor cost.
The host‐ and microhabitat olfactory location by Fopius arisanus suggests a broad potential host range

Abstract The identification of infochemicals for parasitoid females is a critical issue in applied and fundamental parasitoid research. The olfactory location of host and its microhabitat by Fopius arisanus (Sonan, 1932) (Hymenoptera: Braconidae), an egg‐pupal parasitoid of fruit flies (Diptera: Tephritidae), is investigated. Potential sources of volatiles are placed in opaque traps and tested in field cages, under seminatural conditions. Fopius arisanus females respond positively to synomones from mango leaves and from fruits belonging to many botanical families, including the nonhost plant strawberry. They prefer fruits infested by Tephritidae to uninfested ones but do not discriminate between fresh and old infestations. Fopius arisanus females are attracted by the odours of faeces of the tephritid fly Bactrocera zonata. They exhibit remote detection of a volatile kairomone coating the egg mass of all tested Tephritidae species but absent in the egg mass of the Muscidae Stomoxys calcitrans. All these infochemicals are volatile but only those emanating from fruit and from faeces are attractants perceived before landing. The relationships between this apparent generalist behaviour and the dietary specialization of F. arisanus are discussed, according to its ecology and behaviour in its natural environment.
Microbiological and Sensory Quality of Milk on the Domestic Market

Abstract The evaluation of the microbiological and sensory quality of 30 assortments of market milk was the objective of the presented research. The study also compared the sensory profile of selected samples of milk differing in preservation method. Microbiological tests included determination of the presence and number of Enterobacteriaceae and the total number of microorganisms. Sensory characteristics of all the milk samples was performed by scaling method (5-points scale). Selected samples of milk were additionally assessed by means of profile method. Microbiological tests showed satisfactory microbiological purity of milk, which indicates the effectiveness of the heat treatment and the lack of secondary contamination. Regardless of the preservation method, all the evaluated milk samples were characterised by a high sensory quality (4.25-5 points). There were no changes in smell and taste, resulting from the development of undesirable microflora. The tested samples of milk differing in the preservation method (sterilisation, pasteurisation at high temperature and subjected to microfiltration and low pasteurisation) varied in the sensory profile. Milk pasteurised at high temperature was characterised by the most harmonised overall quality.
Integrated Experimental and Numerical Comparison of Different Approaches for Planar Biaxial Testing of a Hyperelastic Material

Planar biaxial testing has been applied to a variety of materials to obtain relevant information for mechanical characterization and constitutive modeling in presence of complex stress states. Despite its diffusion, there is currently no standardized testing procedure or a unique specimen design of common use. Consequently, comparison of results obtained with different configurations is not always straightforward and several types of optimized shapes have been proposed. The purpose of the present work is to develop a procedure for comprehensive comparison of results of biaxial tests carried out on the same soft hyperelastic material, using different types of gripping methods and specimen shapes (i.e., cruciform and square). Five configurations were investigated experimentally using a biaxial test rig designed and built by the authors, using digital imaging techniques to track the displacements of markers apposed in selected positions on the surfaces. Then, material parameters for a suitable hyperelastic law were determined for each configuration examined, employing an inverse method which combines numerical simulations with the finite element method (FEM) and optimization algorithms. Finally, efficiency of examined biaxial configurations was assessed comparing stress reductions factor, degree and uniformity of biaxial deformation, and operative strain ranges.
Antioxidant Enzyme Activity and Malondialdehyde Concentration on Broiler Fed Contain Lauric Acid and Areca vestiaria Giseke

The objective of the study was to determine antioxidant enzyme activity and concentration of malondialdehyde on broiler which consumed feed containing lauric acid and natural antioxidant from Areca vestiaria Giseke. The study used 240 day-old chicks of Lohmann MB 202 P strain placed randomly at 24 experimental cage units (10 chickens each) of the litter system. The average temperature of the cage at the study was 25.80 to 32.080 C with relative air humidity rate of 67.69 to 86.20%. The research method followed a Factorial Completely Randomized Design 2 x 4 with 3 replications. The first factor was the source of lauric acid in feed, i.e. conventional coconut oil (CO) and pure lauric acid (LA). The second factor was the source of antioxidant in the form of dosage of Areca vestiaria (AV) and vitamin E supplementation (TF) with four levels of AV, ie 0, 625 mg.kg-1, 1250 mg.kg-1, and TF at a dose of 200 mg . kg-1 feed. Feed and drinking water were given ad libitum. Meat sampling to measure SOD, catalase and MDA was taken at the end of the study by first chickens were fasted for ± 8 hours (overnight). The sample used was right breast meat of experimental male chicken. The data were average from three experimental chickens. The data obtained were analyzed for the variant with the general linear model on MINITAB (version 16), then tested the differences between treatments using Tukey's honestly significant difference (HSD). The results showed that the source of laurate had a significant effect on SOD, catalase, and MDA, while antioxidant concentration significantly decreased SOD and MDA compared with control. The interaction between lauric sources and antioxidant concentrations affected catalase and MDA. The use of coconut oil as much as 3% and antioxidant supplementation of Areca vestiaria Giseke in feed at a dose of 1250 mg kg-1 could decrease lipid oxidation product of meat to produce a healthy food product.
Systematic Literature Studies

Purpose: Eco-innovation appears to be at the very heart of the European Union policy. It is of crucial importance for both single companies and the whole economic systems. At the same time eco-innovation is driven by the countless factors. Thus the purpose of the present research was to indicate the determinants of the efficiency of eco-innovation. Design/methodology/approach: The research relied on the systematic literature studies performed with the use of SALSA (Search, AppraisaL, Synthesis, Analysis) method. It focused on the papers published between January 2000 and June 2016. A total of 469 publications were examined selected form Scopus database. The precise appraisal procedure allowed indicating the ones including the determinants of the efficiency of eco-innovation. Findings: The studies of literature allowed indicating a total of 24 determinants. Moreover the results indicate that the determinants of the efficiency of eco-innovation may be divided based on two criteria. The first includes costsrelated and revenues-related determinants. The second includes strategic and operational levels. Research limitations/implications Together eleven publications were omitted in the research due to their incompletion or inaccessibility. Practical implications: Stimulating eco-innovation seems vital for all companies. Delivering a comprehensive set of the determinants of its efficiency will support executives in managing eco-innovation. Originality/value: The paper attempts to fulfil the research gap concerning the determinants of the efficiency of ecoinnovation.
Tough-mindedness and the enjoyment of negative emotions in music: a psychophysiological investigation

A fundamental question in musical literature is: how it is possible to enjoy music that expresses negative emotions? Three explanations for this problem have been postulated: 1) listeners experience an inherently pleasant ‘musical’ emotion that is unrelated to music’s emotional content (the aestheticist position), 2) listeners perceive emotions in music but do not experience them (the cognitivist position), 3) listeners experience emotions that match the emotional content of music (the emotivist position). To address this issue, this study examined the relationship between participants’ reported emotional reactions to presentations of emotional music and sounds, and their physiological responses (including facial EMG, startle reflex, heart rate and GSR). Physiological responses were found to vary with the emotional pleasantness and intensity of sounds, but not music, thereby supporting the cognitivist account. In addition, the relationship between Eysenck’s Toughmindedness or Psychoticism (P) dimension, and reported enjoyment was examined. Compared with tender-minded individuals, high P participants reported significantly greater liking for highly arousing, emotionally unpleasant music, and a marked disliking for emotionally unstimulating music. It is concluded that this result is reflective of the sensation-seeking component of P.
