VLT/X-Shooter spectroscopy of the afterglow of the Swift GRB 130606A - Chemical abundances and reionisation at z ~ 6

Context. The reionisation of the Universe is a process that is thought to have ended around z ~ 6, as inferred from spectroscopy of distant bright background sources, such as quasars (QSO) and gamma-ray burst (GRB) afterglows. Furthermore, spectroscopy of a GRB afterglow provides insight in its host galaxy, which is often too dim and distant to study otherwise. Aims. For the Swift GRB 130606A at z = 5.913 we have obtained a high S/N spectrum covering the full optical and near-IR wavelength region at intermediate spectral resolution with VLT/X-Shooter. We aim to measure the degree of ionisation of the intergalactic medium (IGM) between z = 5.02−5.84 and to study the chemical abundance pattern and dust content of its host galaxy.Methods. We estimated the UV continuum of the GRB afterglow using a power-law extrapolation, then measured the flux decrement due to absorption at Lyα,β, and γ wavelength regions. Furthermore, we fitted the shape of the red damping wing of Lyα. The hydrogen and metal absorption lines formed in the host galaxy were fitted with Voigt profiles to obtain column densities. We investigated whether ionisation corrections needed to be applied. Results. Our measurements of the Lyα-forest optical depth are consistent with previous measurements of QSOs, but have a much smaller uncertainty. The analysis of the red damping wing yields a neutral fraction xH i 5.6. GRBs are useful probes of the ionisation state of the IGM in the early Universe, but because of internal scatter we need a larger statistical sample to draw robust conclusions. The high [Si/Fe] in the host can be due to dust depletion, α-element enhancement, or a combination of both. The very high value of [ Al/Fe ] = 2.40 ± 0.78 might be due to a proton capture process and is probably connected to the stellar population history. We estimate the host metallicity to be −1.7 < [ M/H ] < −0.9 (2%−13% of solar).
On the phylogenetic affinities of Centrolabrus trutta and Centrolabrus caeruleus (Perciformes: Labridae) to the genus Symphodus : molecular, meristic and behavioural evidences.

Phylogenetic analysis of partial 12S and 16S mitochondrial rDNA regions, together with meristic and ethological data, has revealed that Centrolabrus trutta (Lowe, 1833), a species occurring in the Canaries and Madeira, and its close relative Centrolabrus caeruleus (Azevedo, 1999) from the Azores, are more closely related to most species of the genus Symphodus than to Centrolabrus exoletus (Linnaeus, 1758). Underwater behavioural observations showed that C. trutta, like C. caeruleus, shares with most Symphodus species sexual dichromatism, male nest building and male parental care of the eggs, traits that are absent in C. exoletus. The low number of base substitutions found between C. trutta and C. caeruleus indicates that these species are very closely related. The 16S rDNA data suggest that C. trutta, C. caeruleus and S. roissali form a monophyletic group. The analysis of the 16S rDNA data also showed that S. melanocercus is the sister species of C. exoletus and it is not closely related to the species of Symphodus included in this study. Lack of nest building and parental behaviour in S. melanocercus, and its marked divergence to other members of the genus Symphodus in meristic characters, also stress its affinity with C. exoletus and its separation from the remaining species of Symphodus. Our data and the evidence available in the literature led us to propose the inclusion of C. trutta and C. caeruleus in the genus Symphodus, while S. melanocercus must be transferred to the genus Centrolabrus.
TIME-SERIES ANALYSIS OF THE SOLOW GROWTH MODEL

I generalise the Solow growth model (Solow, 1956) to allow the savings rate and the population growth rate to vary over time. I formulate the model as a cointegrated vector autoregressive (CVAR) model on Error-Correction-Form (ECM) in per capita output, the savings rate and the growth rate of population and derive the implied restrictions on the long-run matrix for all possible numbers of common stochastic trends. For each of the G7 countries and Denmark, Norway and Sweden, I estimate the number of common stochastic trends, impose the relevant restrictions, and estimate the model. I test the validity of the restrictions implied by the Solow model and evaluate the estimated parameters. I argue that using this structural time-series approach circumvents many of the problems associated with cross-section estimation of the Solow growth model identiﬁed by e.g. Durlauf and Quah (1999) and Durlauf et al. (2005). Overall, the Solow model describes the data reasonably well.
Mid-Career Employees Embracing Technology (MEET): A Case Study

The importance of information technology (IT) for modern business and, indeed, research in general cannot be questioned, as its sheer pervasiveness adequately attests. However, simplistic views of technological utopianism are now being offset by accounts of technological dystopianism. Clearly organizational management have wholeheartedly subscribed to an IT future as a staggering 41 percent of total capital expenditure in US organizations currently goes on IT. However, organizations face enormous difficulty in trying to achieve successful training programmes in the use of IT. This research study involved the construction and implementation of an IT training programme for mid-career employees in a large multinational organization. Davis (1989) identified two constructs as relevant to user acceptance of technology, namely ease of use (EOU) and perceived usefulness (PU). These constructs were operationalised into a set of principles to underpin the training programme which was delivered in two phases, each specifically addressing one of Davis’ constructs.
An improved adsorption method for the characterization of water-based supercapacitor electrodes

The specific surface area is a key characteristic of carbon materials used in supercapacitor electrodes. In this paper, the use of a methylene blue technique for specific surface area determination is presented. Values for the specific surface area, determined by a new method, provide better correlation with theoretical values for the specific electrical capacity of highly-porous carbon electrodes than the values measured by the common BET method. Additionally, the methylene blue adsorption method is thought to characterize carbon adsorption activity in relation to a supercapacitor electrolyte.

Bargaining Behavior in Personal Selling and Buying Exchanges

"Five defining characteristics of negotiations are used to emphasize the need to develop an adequate social context into para-simulations of marketing exchanges. Some extant marketing games of exchange are criticized as being too far removed from the natural Situation they attempt to simulate. A Car Dealers Game is presented which is believed to meet the essential characteristics of an actual marketing exchange. Empirical test results using the Car Dealers Game are reported which support most of 12 hypotheses derived from a simple framework of buyer-seller exchanges. The use of full cycle behavioral research (from lab to field to lab to field) on marketing exchanges is advocated including observation and manipulation of antecedent, strategic decision-making, and process variables in both laboratory and natural locations.

Eliciting the Financial Challenges Facing Emerging Contractors in Developing Countries Using the Critical Incident Technique: A Case of South African Construction Industry

The purpose of this paper was to determine the financial critical incidents that are encountered by emerging contractors in the construction industry in Gauteng, South Africa. The methodology of assessment was based on critical incident technique, a qualitative method which has been considered reliable in tourism and hospitality studies. An interview guide which was evaluated in terms of reliability and validity was used to collect critical incidents from the respondents. Based on the interviews conducted, the respondents highlighted twenty eight financial critical incidents perceived to have an impact or impacts on Emerging Contractors’ performance. The incidents identified were the inability of Emerging Contractors to properly manage cash flow, poor budgetary planning and cash flow, poor financial decision making and lack of collateral. In order to improve Emerging Contractors’ performance, executives are required to plan construction projects in order to guide their execution and control. The limitation of the study was that the perceptions drawn were extracted from 12 respondents who represented emerging contractors in Gauteng Province. Therefore, the results of the study cannot be generalised to the entire South Africa construction industry, however they can be used as part of the solution towards Emerging Contractors’ performance.
Anxiolytic and CNS depressant effects of ethanolic extract of cleome brachycarpa revealed after neuropharmacological screening

Plant extracts have been used since ancient times for treatment of different diseases. They contain phytochemicals which possess multiple therapeutic effects. The aim of this study was to explore neuropharmacological effects of Cleome brachycarpa. Ethanolic extract of Cleome brachycarpa was diluted in DMSO and administered orally at 300mg/kg according to weight of animals. Various CNS screening tests have been performed on mice after acute dosing. The results showed decreased number of cage crosses, head dip, central square and peripheral square crossing, decreased struggling time in FST and increased time in light box in light and dark test. Thus it is concluded that Cleome brachycarpa possesses anxiolytic and CNS depressant effect after acute dosing.
Shape-Memory Nanofiber Meshes with Programmable Cell Orientation

In this work we report the rational design of temperature-responsive nanofiber meshes with shape-memory properties. Meshes were fabricated by electrospinning poly(ε-caprolactone) (PCL)-based polyurethane with varying ratios of soft (PCL diol) and hard [hexamethylene diisocyanate (HDI)/1,4-butanediol (BD)] segments. By altering the PCL diol:HDI:BD molar ratio both shape-memory properties and mechanical properties could be readily turned and modulated. Though mechanical properties improved by increasing the hard to soft segment ratio, optimal shape-memory properties were obtained using a PCL/HDI/BD molar ratio of 1:4:3. Microscopically, the original nanofibrous structure could be deformed into and maintained in a temporary shape and later recover its original structure upon reheating. Even when deformed by 400%, a recovery rate of >89% was observed. Implementation of these shape memory nanofiber meshes as cell culture platforms revealed the unique ability to alter human mesenchymal stem cell alignment and orientation. Due to their biocompatible nature, temperature-responsivity, and ability to control cell alignment, we believe that these meshes may demonstrate great promise as biomedical applications.
Temperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures

(Received 17 Sep. 2017; Revised 11 Oct. 2017; Accepted 25 Nov. 2017; Published 15 Dec. 2017) Abstract: Recently, photonic crystals doped with liquid crystal (LC) material have gained much research interest. In this article new ternary one-dimensional photonic crystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwiched by two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2, SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect of temperature on transfer band gap of these photonic crystals is investigated with transferred matrix method. The results show that in all four structures PBG for extraordinary ray (ne) is very large than ordinary ray (no) and with increasing of temperature, PBG shifts to red wavelength. PBG width is very vast and variation of the figure with respect temperature is very sharp for SiO2/UCF35/CaF2 structure. Also, the suggested design takes high tunability due to the infiltration of the LC material. One can use the proposed structure as temperature sensing device, narrow band optical filter and in many optical systems.
LIMITATIONS ON THE GINZBURG CRITERION FOR DIRTY SUPERCONDUCTORS

The contributions of superconducting fluctuations to the specific heat of dirty superconductors are calculated, including quantum and classical corrections to the ‘usual’ leading Gaussian divergence. These additional terms modify the Ginzburg criterion, which is based on equating these fluctuation-generated contributions to the mean-field discontinuity in the specific heat, and set limits on its applicability for materials with a low transition temperature.
Corporate political resources and the resource-based view of the firm

Several authors looking at firms operating in regulated markets or, more generally, attempting to influence public policies, argue that a critical aspect to consider is whether these firms possess specific political resources; i.e. a set of unique political assets and skills that might prepare these firms to participate in policy debates, face the rivalry of competing interest groups and shape policy decisions (Boddewyn, 1994; Dean and Brown, 1995). Similar to the resource-based view (RBV) of the firm, which holds that a firm’s resources that are rare, inimitable, non-substitutable and valuable may result in sustained competitive advantage (Wernerfelt, 1984), it has thus been argued that firms, in many cases, should also develop political resources with similar attributes. Baron (2003) argues, for instance, that ‘nonmarket assets, and the competencies that flow from them, can give a firm a nonmarket advantage. Distinctive competencies and firm-specific nonmarket assets generate value as a function of how costly it is for market and nonmarket rivals to replicate them’ (2003: 42). A similar proposition can be found, in different forms, in Dahan (2005), Keim and Baysinger (1988), Maijoor and Van Witteloostuijn (1996), Oliver and Holzinger (2008) or Wei (2006), suggesting that the RBV can be applied in a straightforward manner when it comes to studying corporate political resources. In this essay, I challenge this proposition and argue that important modifications to the original RBV analysis need to be considered to really develop a theory of political resources and why they matter for firms. Rare, inimitable and non-substitutable resources certainly exist in political environments; however, I show that these criteria are not necessary conditions for political resources to matter and that other criteria are in fact as important, or even more important, in political environments. Building a theory of firm political resources probably needs to start with a good theoretical understanding of the specificities of political arenas rather than with an attempt to directly extrapolate from the RBV as used for economic arenas.1 The first two sections that follow summarize the problems with a pure RBV view – and particularly its focus on hard-to-imitate resources2 – for political arenas, both at the empirical and the theoretical level. The last section offers directions which, I think, could set future research on a more promising path.
Local Heuristics and an Exact Formula for Abelian Surfaces Over Finite Fields

Abstract Consider a quartic $q$ -Weil polynomial $f$ . Motivated by equidistribution considerations, we define, for each prime $\ell$ , a local factor that measures the relative frequency with which $f$ $ \bmod \,\ell $ occurs as the characteristic polynomial of a symplectic similitude over ${{\mathbb{F}}_{\ell }}$ . For a certain class of polynomials, we show that the resulting infinite product calculates the number of principally polarized abelian surfaces over ${{\mathbb{F}}_{q}}$ with Weil polynomial $f$ .
Alternative artificial incubation system for intensive fry production of Nile tilapia (Oreochromis niloticus)

Jar incubation system is a well established artificial incubation system for intensive fry production of Nile tilapia. However, this system needs special hatchery structure and huge amount of water for circulation of eggs. The present study aimed to explore a simple, economic and water efficient alternative incubation system appropriate for small-scale hatchery operators. Two incubation systems, i.e. atkin incubation system and aquarium incubation system were compared with jar incubation systems in terms of water use, hatching rate and subsequent survival of larvae. Results showed that the amount of water used was significantly higher in atkin (127.0±3.1 m) and jar (36.8±4.9 m) incubation systems compared to aquarium (0.05±0.0m) incubation system. The hatching percentage was significantly higher in jar incubation system (95.5±0.6%) compared to aquarium (65.2±7.7%) and atkin (57.8±2.2%) incubation systems. Hatching tended to occur slightly earlier in the jar incubator than other systems. After 7 days of rearing, the mean larval survival rate was highest in jar incubation (96.9±0.5%), intermediate in aquarium incubation (90.9±3.4%) and lowest in atkin incubation (81.0±3.1) system (P˂0.05). The dissolved oxygen was significantly higher in aquarium (6.1±0.0 mg/L) than jar (3.0±0.0 mg/L) and atkin (3.0±0.1 mg/L) incubation systems. Further experiments indicated that about 5000 eggs can be successfully hatched with a hatching rate of 95% and reared to swim-up fry in in 50 L size glass aquarium with water exchange twice daily. This system is best suited for incubation of late stage eggs and rearing of newly hatched larvae up to free swimming stage. The results indicate that aquarium incubation can be used as an alternative of jar incubation system for Nile tilapia eggs, especially in water scarce areas.
NUSIKALTIMŲ KLAIPĖDOJE ŽEMĖLAPIAVIMAS: NUO NUSIKALTIMŲ FIKSAVIMO IKI AIŠKINIMO IR PREVENCIJOS

The article discusses the classic sociological question about the links between poverty and delinquency, whether the urban areas with a dense concentration of people living in social housing, common lodging-houses and hostels are more prone to crimes? Does living nearby such social objects means a higher risk for nearby residents? The article suggests that social housing, common lodging-houses and hostels meant for homeless asylum seekers and their families could only hypothetically be considered to be the areas with higher crime rates. Using the data available at the Department of Social Housing of Klaipėda City Municipality about the location of such housing in the city (localisation structure), the method of crime mapping, and the opportunities provided by a Geographic Information System, we have attempted to evaluate empirically the links between delinquency and the urban areas populated by socially vulnerable and economically disadvantaged people. The article provides the preliminary data of the research. This research has been funded by a grant (MIP-085/2014) from the Research Council of Lithuania.

11 12 Ab Q2 stract 13 & Introduction Tree genetic improvement programs usually 14 lack, in general, pedigree information. Since molecular 15 markers can be used to estimate the level of genetic 16 similarity between individuals, we genotyped a sample of a 17 Portuguese Eucalyptus globulus breeding population—a 18 reference population of 125 individuals—with 16 micro19 satellites (SSR). 20 & Materials and methods Using genotypes from the 21 reference population, we developed a simulation approach 22 to recurrently generate (10 replicates) virtual offspring 23 with different relatedness: selfed, half-sib, full-sib and 24 unrelated individuals. Four commonly used pairwise sim25 ilarity coefficients were tested on these groups of simulated 26 offspring. Significant deficits in heterozygosity were 27 found for some markers in the reference population, 28 likely due to the presence of null alleles. Therefore, the 29 impact of null alleles in the relatedness estimates was 30 also studied. We conservatively assumed that all 31 homozygotes in the reference population were carriers 32 of null alleles. 33 & Results All estimators were unbiased, but one of them 34 was better adjusted to our data set, even when null alleles 35 were considered. The estimator’s accuracy and precision 36 were validated with individuals of known pedigree obtained 37 from controlled crosses made with the same reference 38 population’s parents. Additionally, a clustering algorithm 39 based on the estimator of choice was constructed, in order to 40 infer the relatedness among 24 E. globulus elite individuals. 41 We detected four putatively related elite individuals’ pairs 42 (six pairs considering the presence of null alleles). 43 & Conclusions This work demonstrates that in the absence 44 of pedigree information, our approach could be useful to 45 identify relatives and minimize consanguinity in breeding 46 populations.
Institutional Development, Governance, and Ethnic Politics in South Sudan

This article discusses ethnicity and socio-cultural complexity in governance, political systems, and bureaucratic institutions in South Sudan. Using the partially thematic and content analysis of the grounded theory analysis, the major themes and categories outline patterns of cultural norms and values in the absence of national identity that affects the pace of sustainable peace, economic development, good governance, and democratic transformation in the country. The outcome suggests that South Sudan continues to face multi-faceted socio-cultural, political, and economic challenges in its transition from ethno-centric system to viable democratic governance. This includes a genuine quest for nation-building transformation to a viable state, establishment of functional system, security, and rule of law and order in the country. The outcomes suggest that South Sudan Policymakers has paid minimum attention in eradication of poverty, high illiteracy rate and dogmatic ethnic values. Nonetheless, the country is in a dire need for traditional and cultural peace-building process among various ethnic-groups and communities as a corner stone for a sustainable socio-economic and political development.
