Unregulated use of TBT-based antifouling paints in Israel ( eastern Mediterranean ) : high contamination and imposex levels in two species of marine gastropods

The use of tributyltin (TBT)-based antifouling paints is unregulated in Israel, and levels of contamination are high along the Mediterranean coastline there. This is indicated by concentrations of butyltins found in the tissue, and by irnposex in the whelks Strarnonita haemastoma and Hexaplex trunculus. Both the old (since 1974) and new (since late 1995) marinas we studied are hotspots of pollution. Imposex indices were very high at the old manna (RPSI > 100, VDSI 4 to 5) ; all female H. trunculus and some S. haemastoma were sterile within a dlstance of ca 1 km from it. The new marina offered a unique opportunity to witness the rapid and intense response of the whelks to TBT pollution in an open coastline. Despite a marked decrease in levels of contarnmation at distances of 1 to 2 km from both marinas, there were nevertheless detectable levels of butyltins sufficient to cause imposex in reference sites far from high shipping activity. There is evidence that TBT contamination affects abundance and relatlve growth rates, of male and female, of the 2 whelks around the marinas. Differences in biological response to TBT were observed between the 2 whelk species: S. haemastoma had higher levels of organotins than H. trunculus in most study sites, which may be related to different sensitivity or accumulation rates. In S. haemastorna a male-biased sex ratio was revealed around the old Tel Aviv marina, which may be derived from either female mortality or from a complete sex change in some females. Further development of marinas at coastal resorts is undesirable, certainly in the absence of regulations limiting the use of TBT-based antifoulants, and the establishment of such regulations is highly recommended.
Stability regimes of a dilatant, fluid‐infiltrated fault plane in a three‐dimensional elastic solid

[1] We investigate in a systematic parameter space study dilatant effects on slip evolution of a fluid-infiltrated fault in the continuum limit. The fault is governed by rate- and state-dependent friction and an empirical law for porosity evolution. We focus on the response of systems as a function of fluid-related parameters, such as the degree of overpressurization, dilatancy and diffusivity. This study emphasizes the exploration of the parameter space for homogeneous along-strike properties to investigate the evolution of spatiotemporal slip depending on hydromechanical processes. Three types of responses emerge. First, system-wide unstable stick-slip develops for drained conditions, and for undrained conditions if mechanisms leading to an increase in pore space are less effective. The critical stiffness depends on hydraulic diffusivity and dilatancy, which is shown to correspond with interevent times of simulated stick-slip events. During instabilities the evolution of hydraulic variables differ significantly between drained and undrained conditions. Second, stable creep is a result of dilatant processes. Third, systems situated in transitional stability regimes develop nonuniform slip pattern in space and time, revealing a possible explanation for rupture termination and observed stable afterslip. Although these patterns are produced by models located in transition zones of the parameter space, the occurrence of heterogeneous slip evolution is persistent for an extensive range of parameter values. Since transition zones contain an broad range of plausible conditions in the crust, they do not represent extreme cases.
MODEL OF AN ADAPTIVE ENERGY HARVESTER WITH ELECTRO-RHEOLOGICAL FLUID

The aim of this paper is to propose and analyse an energy harvester able to adapt to the external vibration frequency and to the load impedance in order to maximize the harvested energy. The design problem consists in determining the applied electric filed to a rheological fluid, for gathering the maximal power from an energy harvesting device based on an inertial mass consisting of a magnetic core in an energy harvesting coil. The optimization regards the adjustment of the damping for achieving the matching between the resonance frequency of the energy harvester moving element (inertial mass) and the tremor frequency of the patient or the matching to the load. A design configuration for an energy harvester specifically conceived for FES in Parkinson disease is presented. In the subsidiary, we specify the processing steps for the tremor signal.
A staggered grid Jin–Xin relaxation method used to solve the Burgers equation

Burgers equation is considered. Burgers equation has applications in fluid dynamics, traffic flows, etc. It mimics the Navier–Stokes equations. Therefore, in this paper, an accurate method to solve the Burgers equations is sought. Jin–Xin relaxation method has been an active research area for collocated grids. However, the literature suggests that it has never been tested to solve models on staggered grids. In this paper, we test the performance of the Jin–Xin relaxation method in solving a hyperbolic problem on staggered grids. Our research results show that the Jin–Xin method is successful in solving the Burgers equations on staggered grids.
Genetic Diversity of Quantitative Traits of Sugarcane Genotypes in Ethiopia

Information about the amount and distribution of genetic variation in germplasm collections is important for their efficient management and effective utilization in plant breeding. Therefore this study was conducted to assess genetic diversity of sugarcane germplasm in Ethiopia. An experiment comprising of 400 sugarcane genotypes (174 local and 226 introduced) was conducted between March 2012 and October 2013 at Wonji and Metehara Sugar Estates using partial balanced lattice design with two replications. Data was recorded on 21 quantitative characters which included cane yield and its components, sugar yield and sugar quality traits. ANOVA portrayed highly significant differences (P < 0.01) among the genotypes for 21 quantitative traits. Cluster analysis revealed intra cluster D2 values ranging from 2.16 - 10.60 and inter cluster from 7.24 - 5864. There were six principal components accounting for 79.26% of the total variation in the tested materials. Millable stalk count, single cane weight, stalk diameter, cane yield, sugar yield and sugar quality traits showed high positive loading on the first two PCs and accounted for most of the variation observed among the genotypes. Therefore, this study suggested that the important characters responsible for diversity in the sugarcane genotypes could be grouped in two principal components namely “Yield” and “Quality” with “Yield” traits being comparatively more important than “Quality”. Genotypes clustered for high mean values of various traits could be exploited for further improvement of the crop either through selection or through hybridization. The clusters having high mean value for yield could be selected for yield per se as well.
HESS observations of $\gamma$-ray bursts in 2003–2007

Very-high-energy (VHE; >~100 GeV) gamma-rays are expected from gamma-ray bursts (GRBs) in some scenarios. Exploring this photon energy regime is necessary for understanding the energetics and properties of GRBs. GRBs have been one of the prime targets for the H.E. S.S. experiment, which makes use of four Imaging Atmospheric Cherenkov Telescopes (IACTs) to detect VHE gamma-rays. Dedicated observations of 32 GRB positions were made in the years 2003-2007 and a search for VHE gamma-ray counterparts of these GRBs was made. Depending on the visibility and observing conditions, the observations mostly start minutes to hours after the burst and typically last two hours. Results from observations of 22 GRB positions are presented and evidence of a VHE signal was found neither in observations of any individual GRBs, nor from stacking data from subsets of GRBs with higher expected VHE flux according to a model-independent ranking scheme. Upper limits for the VHE gamma-ray flux from the GRB positions were derived. For those GRBs with measured redshifts, differential upper limits at the energy threshold after correcting for absorption due to extra-galactic background light are also presented.
Neighbourhood effects, preference heterogeneity and immigrant educational attainment

This paper investigates differences between the educational attainment of immigrants, children of immigrants and native-born individuals in Australia by using Australian Youth Survey (AYS) data combined with aggregate Australian Census data. Differences in educational attainment are decomposed into: (i) typical demographic and socio-economic sources common to all ethnic groups; (ii) unobserved region of residence and region of origin effects; and (iii) neighbourhood effects such as degree and ethnic concentration of particular ethnic groups in different neighbourhoods. A theoretical model incorporating these effects is proposed but structural estimation is not possible for lack of appropriate data. Instead, a reduced form methodology is proposed and employed. The empirical results identify positive ethnic neighbourhood effects in high school completion and university enrolment for some immigrant groups in Australia, in particular first and second generation immigrants from Asia. The results indicate that it is not just the size of the ethnic network but the ‘quality’ of the network that is important.
Size related variability in the summer diet of the blackfin tuna (Thunnus atlanticus Lesson, 1831) from Tobago, the Lesser Antilles

Summary Blackfin tuna (Thunnus atlanticus) is a small epipelagic oceanic species known only from the western Atlantic. In Tobago, the Lesser Antilles, blackfin tuna is caught by the artisanal fishery. The diet of this species was examined during the summer of 2004 for fish landed at the Charlotteville fish market in Tobago. T. atlanticus ranged from 32 to 91 cm FL (0.7–12.4 kg). Overall numerical abundance of prey items comprised fish (48%), crustaceans (46%) and cephalopods (6%). Prey species included small pelagics such as anchovies (ranked as most important prey overall), juveniles of larger pelagics such as jacks, juveniles of fish found in coral reef communities as adults, e.g. squirrelfishes, and some mesopelagic species. The importance of major diet categories differed significantly with predator size, with fishes becoming more important and crustaceans less important with increasing size of the blackfin tuna. This study has improved our scant knowledge of the blackfin tuna diet in the Lesser Antilles.
Genetic Diversity Analysis of Some Barley Genotypes for Salt Tolerance Using SSR Markers

The aim of the present work was to evaluate the performance of 20 barley genotypes and find out the genetic diversity of these genotypes for salt tolerance using simple sequence repeats during two consecutive seasons; 2009/2010 and 2010/2011. Twenty barley genotypes differed in their tolerance potentiality against salinity were planted in two screening field experiments at two locations; Sakha, North Egypt (as a control) and El-Serw (as saline site) to detect their tolerance to salt stress. They were planted in a randomized complete block design with three replicates. Results revealed that the Egyptian barley cultivars Giza 123, California Mariout and genotype no.12 (line 12 from Cyprus) were salt tolerant besides genotype no.9 (Saiko) giving a moderate salt tolerance response and they all exhibited the highest mean values for some traits such as heading date and plant height under saline condition. Out of ten primers used, only six primers (Bmac0209, Bmac0316, Scssr03907, Bmag770, HVM67 and HVHOTRI) generated clear patterns with high polymorphism. This six discriminatory primer pairs were used to evaluate the genetic diversity of salt tolerance in the 20 barley genotypes. Based on phylogenic trees the data from the dendrogram constructed with SSR markers showed four clusters. All the salt tolerant genotypes and some moderately salt tolerant genotypes were found in two closely related clusters, while all the sensitive genotypes and moderate ones were closely related in the other two clusters. It was concluded that those barley genotypes which showed salt tolerance could serve as potentially novel germplasm that could be exploited for the development of new breeding lines with high level of salinity tolerance and to accelerate genetic advancement in barley and better cost efficient compared to conventional and tedious screening procedures under saline field conditions.
ERT and GPR survey of collapsed paleocave systems at the western border of the Potiguar Basin in northeast Brazil

Collapsed paleocave systems are carbonate reservoirs with high internal spatial complexity that are the result of several stages of karst processes. Paleocave-related reservoirs can be spread over large areas with significant thicknesses that are favourable for hydrocarbon exploration. Nevertheless, few studies have provided a detailed understanding of the strong lateral heterogeneity of these reservoirs and their complex karst-controlled development using modern karst terrain analogues. To elucidate this issue, the internal architecture of a collapsed paleocave system has been mapped accurately at the western border of the Potiguar Basin in Northeastern Brazil. The collapsed paleocaves outcrop in an escarpment that delimits the carbonate platform from the transgressive phase of the basin. Electrical resistivity tomography (ERT) and ground-penetrating radar (GPR) sections were acquired parallel and perpendicular to a road cut and served to parameterize the geophysical signatures of the collapsed paleocaves and the host rocks. The collapsed paleocaves were mapped by identifying high-resistivity zones and high-amplitude ground-penetrating radar reflectors. In contrast, the host rocks are marked by low to intermediate resistivity and ground-penetrating radar reflections that range from low amplitude to almost transparent. The resistivity data and the ground-penetrating radar attribute of the rootsquare energy enabled the mapping of the complex spatial distribution of the collapsed paleocaves system. At depths of approximately 20 m, the paleocaves are more spread out and eventually become isolated while sometimes being connected vertically through shafts. However, at shallower levels, the paleocaves are interconnected by ducts or coalesce into a system of paleocaves that are hundreds of metres long over an area of 12000 m2. The results of the study show the detailed internal geometry of this paleocave system at a subseismic scale, which enables the identification of the connectivity pattern among these karst features and the porosity and total volume of the reservoir. This system could serve as an outcrop analogue for other collapsed paleocave carbonate reservoirs worldwide.
PRESENT AND FUTURE TIME PERSPECTIVE EFFECTS ON JOB SATISFACTION AND ORGANIZATIONAL COMMITMENT : EVIDENCE FROM MBA MEXICAN STUDENTS

Academic literature and popular press suggest that individuals’ time perspective influences a variety of important life situations. As such, this research posits that present and future time perspective could also affect job satisfaction and organizational commitment. Results obtained from the analysis of a sample of Mexican MBA students suggest that while a present time perspective has a negative but insignificant effect on job satisfaction and organizational commitment, a future time perspective has a positive and significant effect on both attitudes. Results of the investigation are discussed and conclusions are drawn regarding the importance of time perspective in job settings.
H-ATLAS: the far-infrared properties of galaxies in and around the Coma cluster

We describe a far-infrared survey of the Coma cluster and the galaxy filament it resides within. Our survey covers an area of ∼150 deg2 observed by Herschel H-ATLAS (Herschel Astrophysical Terahertz Large Area Survey) in five bands at 100, 160, 250, 350 and 500 μm. The SDSS spectroscopic survey (mr ≤ 17.8) is used to define an area (within the virial radius) and redshift selected (4268 < v < 9700 km s−1) sample of 744 Coma cluster galaxies – the Coma Cluster Catalogue. For comparison, we also define a sample of 951 galaxies in the connecting filament – the Coma Filament Catalogue. The optical positions and parameters are used to define appropriate apertures to measure each galaxy's far-infrared emission. We have detected 99 of 744 (13 per cent) and 422 of 951 (44 per cent) of the cluster and filament galaxies in the SPIRE 250 μm band. We consider the relative detection rates of galaxies of different morphological types finding that it is only the S0/Sa population that shows clear differences between the cluster and filament. We find no differences between the dust masses and temperatures of cluster and filament galaxies with the exception of early-type galaxy dust temperatures, which are significantly hotter in the cluster than in the filament (X-ray heating? ). From a chemical evolution model, we find no evidence for different evolutionary processes (gas loss or infall) between galaxies in the cluster and filament.
CORPORATE SOCIAL RESPONSIBILITY AND ITS IMPACT ON THE CORPORATE DECISION-MAKING PROCESS FOR UNIVERSITY UNDERGRADUATE RESEARCH FELLOWS

Corporate Social Responsibility and Its Impact on the Corporate Decision Making Process for University Undergraduate Research Fellows. (April 2003) Joseph E. Bain Department of Finance Texas AkM University Fellows Advisor: Dr. Arvind Mahajan Department of Finance This study seeks to answer the question, "How does corporate social responsibility (CSR) influence corporate decision making? " It does so in two steps. The first step is the building of a theoretical framework in order to understand the many, vastly different academic theories on CSR. The framework that exists groups thoughts on CSR into three categories, which are as follows: normative stakeholder theory, shareholder wealth maximization theory, and strategic stakeholder theory. Proponents of "normative stakeholder theory" argue that, as a product of society, thc corporation should be held accountable to the demands of society, as seen through their various stakeholders. Believers of "shareholder wealth maximization theory" argue that societal utility is maximized as each unit of society seeks to maximize his or her own utility and, therefore, believe that the principles of CSR dictate that the corporation should be held accountable solely to its shareholders, which are the fundamental owners of the corporation. "Strategic stakcholdcr theory" is a metaphoric bridge between its two counterparts. Strategic stakeholder theory recognizes that a tradeoff exists for the firm between the immediate wishes of all stakcholders. For the long-term profitability of the firm, strategic stakeholder theory recognizes that both financial and non-financial stakeholders must be acknowledged. The recognition of this tradeoff leads to the second half of this study. The second part of this study picks up the debate on the relationship between CSR and firm financial performance. It is argued that this relationship is the underlying assumption that separates shareholder wealth maximization theory, which believes that a firm benefits society by seeking its own ends, and normative stakeholder theory, which believes that a firm does not benefit society by seeking profits. To add to the base of knov;ledge on this topic, a difference of means test is performed on companies that are in the DSI 400, a socially responsive stock index, against companies that are not in the DSI 400. A significant difference was discovered in the attributes measured. It is concluded that the DSI 400 serves as a valid proxy for CSR and further research using the DSI 400 is encouraged.
Title Cheap talk and credibility : The consequences of confidence and accuracy on advisor credibility and persuasiveness Permalink

Is it possible to increase one’s influence simply by behaving more confidently? Prior research presents two competing hypotheses: (1) the confidence heuristic holds that more confidence increases credibility, and (2) the calibration hypothesis asserts that overconfidence will backfire when others find out. Study 1 reveals that, consistent with the calibration hypothesis, while accurate advisors benefit from displaying confidence, confident but inaccurate advisors receive low credibility ratings. However, Study 2 shows that when feedback on advisor accuracy is unavailable or costly, confident advisors hold sway regardless of accuracy. People also made less effort to determine the accuracy of confident advisors; interest in buying advisor performance data decreased as the advisor’s confidence went up. These results add to our understanding of how advisor confidence, accuracy, and calibration influence others. 2013 Elsevier Inc. All rights reserved.
Characterization of heterogeneous fracture compliance using multiple reflections coupled with data-driven Green's function retrieval

The spatial heterogeneity along a fracture is a key determinant for fracture-associated hydraulic properties. We propose a new method to estimate the heterogeneous compliance distribution of a fracture from the reflection response at the fracture surface. For this purpose, we formulate a data-driven approach for Green's function retrieval based on Marchenko equation coupled with the inverse scattering to solve the linear-slip boundary condition. The approach estimates the wavefield along the fracture accurately, including the multiple reflections. Furthermore, it offers the opportunity to estimate compliance using multiple reflections, which was not possible so far. We show this concept by numerically modeling 2D SH waves sensing the heterogeneous tangential compliance of a fracture. Our results show that the use of multiple reflections leads to a better estimation of the heterogeneous fracture compliance than using primary reflection alone, especially for the far offsets on the fracture plane.
First Thoughts on the Incorporation of Cultural Variables into Predictive Modelling

Predictive maps are increasingly used at all administrative levels for purposes of planning and determining policy priorities. However, current methods yield predictions with limited specificity. It is believed that methodological improvements, such as the use of non-environmental variables, will lead to a better performance of the models. The paper aims to show in what way cultural variables can actually be included in predictive modelling.
