Gravina-di-Puglia III: Houses and a Cemetery of the Iron Age and Classical Periods
Authors: du Plat Taylor J. , Dorrell P. G. , Small Alastair 
Published: August 2013

The exploration of the site of Parco S. Stefano began as a rescue operation following the extension of Signor Lorusso's quarry on the right bank of the Gravina. Tombs were known to exist in this locality and a sarcophagus and other burials were found in the first area to be stripped. Signor Losindaco and Professor Vinson, who was working in the area, recovered what sherds they could between 13 and 15 July 1970 and reported the finds to the Soprintendenza alle Antichità of Taranto.The Soprintendente, Professor Lo Porto, requested the assistance of the British School at Rome and Jon Boutelle and his wife were sent down to supervise the rescue work from 20 July 1970, under the direction of the Soprintendenza. They continued in charge until the end of the excavation on 12 September. Dottoressa Lattanzi and Signor Campi visited the site and advised on the work.

Theatrical Life in Republican Rome and Italy
Authors: Rawson Elizabeth 
Published: August 2013

LA VITA TEATRALE NELLA ROMA REPUBBLICANANell'articolo si esamina la vita teatrale in Italia, in particolare in Campania e nel Lazio dal III secolo a.C. fino alla fine della Repubblica, e si sostiene che tra queste regioni e Roma vi fosse in questo campo uno scambio maggiore di quanto normalmente si creda. Le compagnie che parlavano in greco, osco e latino venivano a Roma, e quelle romane facevano tournées fuori Roma, come dimostra un passo frainteso di Lucilio. La Campania guidava ed influenzava Roma non solo nell'architettura teatrale, ma anche sotto altri aspetti: molti autori ‘Romani’, in particolare Titinio, autore delle togatae ambientate nelle città a sud di Roma, forse non nacquero nella capitale, ma solo vi rappresentarono per la prima volta le loro commedie. Molti attori inoltre, a giudicare dal loro nome, sembrano italiani invece che latini, oppure liberti da padroni che lo erano.
Acoustic-like dynamics of amorphous drugs in the THz regime

Published: August 2013

AbstractThe high frequency dynamics of Indomethacin and Celecoxib glasses has been investigated by inelastic x-ray scattering, accessing a momentum-energy region still unexplored in amorphous pharmaceuticals. We find evidence of phonon-like acoustic dynamics and determine the THz behavior of sound velocity and acoustic attenuation. Connections with ordinary sound propagation are discussed, along with the relation between fast and slow degrees of freedom as represented by non-ergodicity factor and kinetic fragility, respectively.
Interdomain contacts control folding of transcription factor RfaH
Authors: Tomar Sushil Kumar , Knauer Stefan H. , NandyMazumdar Monali , Rösch Paul , Artsimovitch Irina 
Published: August 2013

Abstract
Escherichia coli RfaH activates gene expression by tethering the elongating RNA polymerase to the ribosome. This bridging action requires a complete refolding of the RfaH C-terminal domain (CTD) from an α-helical hairpin, which binds to the N-terminal domain (NTD) in the free protein, to a β-barrel, which interacts with the ribosomal protein S10 following RfaH recruitment to its target operons. The CTD forms a β-barrel when expressed alone or proteolytically separated from the NTD, indicating that the α-helical state is trapped by the NTD, perhaps co-translationally. Alternatively, the interdomain contacts may be sufficient to drive the formation of the α-helical form. Here, we use functional and NMR analyses to show that the denatured RfaH refolds into the native state and that RfaH in which the order of the domains is reversed is fully functional in vitro and in vivo. Our results indicate that all information necessary to determine its fold is encoded within RfaH itself, whereas accessory factors or sequential folding of NTD and CTD during translation are dispensable. These findings suggest that universally conserved RfaH homologs may change folds to accommodate diverse interaction partners and that context-dependent protein refolding may be widespread in nature.
Information disclosure by family-controlled firms
Authors: Darmadi Salim , Sodikin Achmad 
Published: August 2013

Purpose
– The purpose of this paper is to investigate the influence of family control on the extent of voluntary disclosure in the annual report of Indonesian listed firms. Further, it seeks to investigate the role of corporate governance mechanisms in explaining the association between family control and voluntary disclosure. Governance mechanisms addressed here include board independence and institutional ownership.

Design/methodology/approach
– This study employs a sample comprising non-financial firms on the Indonesia stock exchange that published the 2010 annual report. The voluntary disclosure index is computed for each sample firm, based on content analysis of the annual report. Cross-sectional regressions are performed to test research hypotheses.

Findings
– Our evidence reveals that family control negatively and significantly influences the extent of information disclosure. This finding suggests that family-controlled firms have lower motivation to disclose additional voluntary information, which might unexpectedly expose private benefits maintained by the controlling family. We also find that the relationship between institutional ownership and disclosure is stronger in family firms. However, independent commissioners do not contribute to improving the extent of disclosure by family firms.

Originality/value
– The present study contributes to the rare existing literature addressing the relation of family control to information disclosure. Further, the role of corporate governance mechanisms in promoting greater information transparency in family-controlled firms is still very rarely examined.
Determination of grape juice concentrate composition
Authors: Mohamadi Sani Ali 
Published: August 2013

PurposeGrape juice concentrate (GJC) composition is affected by different factors including grape type and production conditions. So this study aimed to determine composition and nutrition value of GJC in eight cities in Khorasan province in north east of Iran in order to use the data in nutrition value tables.Design/methodology/approachThe GJC samples (20) were supplied from local supermarkets in nine cities in Khorasan province in Iran. Total and soluble dry matter, total sugar, protein, fat, soluble fiber, ash and pH were determined according to standard methods. Nutritious minerals including calcium, phosphorus, magnesium and iron were detected using atomic absorption spectroscopy method.FindingsThe chemical properties of GJC samples were determined as follows: total dry matter 73.66 percent; protein 1.46 percent, total sugar 68.03 percent; soluble fiber 2.69 percent, ash 0.71 percent and fat 1.08 percent. The average values of pH and brix were, respectively, 4.25 and 65.5°. The mineral content was found as follows: calcium 817 ppm; sodium 0.9 percent; phosphorus 492 ppm; magnesium 1,704 ppm and iron 60 ppm.Originality/valueThe composition and nutritional value of GJC in Iran had not been determined before. The findings on nutritive properties of GJC can be used in nutrition value tables.
Cash acquirers
Authors: Gregory Alan , Wang Yuan‐Hsin 
Published: August 2013

PurposeThis paper investigates the Jensen's free cash flow (FCF) hypothesis in the context of UK cash acquisitions. Under this hypothesis, financial slack induces mangers to acquire targets for cash if such behaviour generates either pecuniary or non‐pecuniary rewards for them, giving rise to a potential agency problem around cash takeovers. We argue that the stronger position of shareholders, as opposed to firm managers, in the UK should help in constraining such potential agency problems around such mergers. Compared to the USA, position, this should make the FCF hypothesis less relevant in the UK.Design/methodology/approachThis paper uses short‐run announcement period returns and long‐run calendar‐time returns in testing our hypotheses.FindingsThis paper shows that low leverage and high FCF may be advantageous provided shareholder monitoring is adequate. By analysing both announcement period and long‐term returns, we show that acquirers with high levels of FCF are superior performers, and that any long‐run under‐performance of cash acquirers appears to be associated with low cash resources and low institutional ownership.Research limitations/implicationsInevitably, long‐run returns measurement is contentious, although we present results from alternative models to mitigate this. Limitations are necessarily imposed by the sample size, meaning that multi‐way partitioning of the data is not feasible.Practical implicationsThe practical implications are that the UK regulatory and institutional ownership regime may actually protect the interests of shareholders and mitigate agency problems.Originality/valueAs far as we are aware, this is the first paper to systematically test FCF, leverage and institutional ownership effects in the context of UK cash acquisitions.
Managerial gambling attitudes: evidence from bank acquisitions
Authors: Doukas John A. , Zhang Wenjia 
Published: August 2013

PurposeThis study investigates the implications of the cumulative prospect theory in the context of US bank acquisitions, with particular emphasis on its probability weighting component. Specifically, we examine whether gambling attitudes matter in US bank takeover decisions. The evidence demonstrates that offer price premiums and target announcement returns are much higher in bank takeover transactions involving targets with gambling (lottery) features (high skewness, high volatility, and low price). Overall, the results indicate that banking acquisitions are influenced by gambling attitudes.Design/methodology/approachTo measure idiosyncratic skewness, we follow Harvey and Siddique (2000) and Kumar (2009) and decompose total skewness into its idiosyncratic and systematic components.FindingsThe evidence demonstrates that offer price premiums and target announcement returns are much higher in bank takeover transactions involving targets with gambling (lottery) features (high skewness, high volatility, and low price). In addition, we find that synergies and bidder announcement returns are lower in lottery‐type acquisitions. The patterns we document are stronger when bidding banks are bigger, target banks are smaller, investor sentiment is above the median, and the Chicago Fed National Activity Index is negative.Originality/valueThis is an original piece of work in the field of banking.
A review of building/infrastructure sustainability reporting tools (SRTs)
Authors: Y. J. Siew Renard , C. A. Balatbat Maria , G. Carmichael David 
Published: August 2013

Purpose
– Buildings/infrastructure are recognised to have a significant impact on the environment and the community, and hence there is pressure on industry practitioners to incorporate environmental and social considerations in addition to the traditional cost, time and quality. The development of sustainability reporting tools (SRTs) to assist in the management of “green” building/infrastructure projects is pivotal in informing on progress in sustainability practices. However, the rapid growth of SRTs in the last decade, with different criteria and methodology, has created complications for stakeholders.

Design/methodology/approach
– The paper provides a comprehensive review of tools to guide practitioners, property investors, policy makers and developers towards making informed choices in “green” building/infrastructure projects. Comparative analyses, benefits and limitations of these tools are discussed in the paper.

Findings
– Some of the findings from the analysis of SRTs include: an emphasis on environmental issues; scoring which does not account for uncertainty or variability in assessors’ perceptions; lack of published reasoning behind the allocation of scores; inadequate definition of scales to permit differentiation among projects; and the existence of non-scientific benchmarks.

Originality/value
– The paper departs from earlier reviews to include a discussion on infrastructure SRTs, life cycle tools, and issues broader than the environment. Changes and additions, subsequent to earlier reviews, have been made to SRTs, making the updated review provided here useful.
Membrane vesicle formation is associated with pyocin production under denitrifying conditions in Pseudomonas aeruginosa PAO1
Authors: Toyofuku Masanori , Zhou Shengmin , Sawada Isao , Takaya Naoki , Uchiyama Hiroo , Nomura Nobuhiko 
Published: August 2013

SummaryMany Gram‐negative bacteria produce membrane vesicles (MVs) that serve as vehicles to mediate intraspecies and interspecies interactions. Despite their ubiquity in Gram‐negative bacteria and their biological importance, how MV formation is regulated is poorly understood. Pseudomonas aeruginosa is a ubiquitous bacterium that is one of the most extensively studied model organism in MVs. Recent studies highlight the importance of a quorum‐sensing signal, Pseudomonas quinolone signal (PQS), in the formation of MVs; however, PQS synthesis requires oxygen and is not produced under anoxic conditions. This situation leads to the question of MV production under anoxic conditions. Here, we examined whether MVs are produced under denitrifying conditions and what kind of factors are involved in the MV production under such condition. Under denitrifying condition, P. aeruginosa PAO1 produced a considerable amount of MVs. Interestingly, pyocin components were found to be accumulated in the isolated MVs. Pyocin‐related protein mutants produced less MVs compared with the wild type. We further indicate that pyocin production is activated by nitric oxide, in which the SOS response is involved. This study presents a regulatory mechanism where pyocin is associated with MV production, and further implies how the environment impacts MV production in P. aeruginosa.
Reconstituting the Possible: Lefebvre, Utopia and the Urban Question
Authors: Pinder David 
Published: August 2013

AbstractWhat roles can utopia play in contemporary critical urban studies? The concept has often been treated warily, sidelined or dismissed. Recent years, however, have seen a revival of interest, as writers, activists and artists have sought openings to urban worlds that are different and better. By returning to aspects of the urban thought and practice of Henri Lefebvre in the 1960s and early 1970s, this article challenges common understandings of utopia and clarifies some of its potential uses for critical urban studies today. It explores Lefebvre's emphasis on the possible, and in particular the importance he attached to extending and realizing the possible through struggling for what seems impossible. Rather than being a free‐floating or endlessly open project, however, this engagement with the ‘possible‐impossible' emerged in critical dialogue with other currents of utopian urbanism, including prospective thought then influential in France. It was also rooted in long‐ standing concerns with the critique of everyday life and with experimentation through projects with urbanists, architects and others. By attending to these often neglected aspects of Lefebvre's utopianism, a series of provocations emerge for addressing the urban question in ways that take seriously not only what urbanization processes and urban life are but also what they could become and how they might be constituted differently.
The utility of distribution data in predicting phenology
Authors: Bishop Tom R. , Botham Marc S. , Fox Richard , Leather Simon R. , Chapman Daniel S. , Oliver Tom H. 
Published: August 2013

Summary

The phenology of many species has been shown to shift under climate change. However, because species respond at different rates, ecological communities may be disrupted leading to species extinctions and loss of ecosystem services. Hence, there is a need to monitor and understand phenological change.

Population data, gathered by standardised monitoring schemes, can be used to this end. However, such schemes require significant organisation and financial resources. Distribution data (georeferenced biological records with dates) are easier and cheaper to collect and may be an unexploited resource for phenology analyses. This would allow analysis of more taxa from more regions of the world. However, distribution data are potentially biased due to the unstandardised behaviour of biological recorders.

Here, the ability of distribution data record dates to accurately predict phenology is investigated by using the British butterfly fauna as a model system. We used the total number of distribution records per unit time across Great Britain as a proxy for butterfly abundance. Phenology metrics of mean flight date and flight period length were then calculated from the resulting abundance–time relationships for each year in a 15‐year time series. These estimates were validated against those generated from a standardised‐effort population monitoring scheme.

We analysed 1 078 328 records from 30 British butterflies and found that distribution data accurately predicted the mean flight date for 22 of the 30 species tested. Flight period length was only predicted accurately for seven of 30 species.

We found a nonlinear but consistent positive relationship between the accuracy of mean flight date estimates and sample size (number of records) at both inter‐ and intraspecific scales. Our results suggest that a threshold sample size of c. 6500 distribution records (430 per year) is a pragmatic compromise between accuracy and recording effort, leading to little loss of accuracy in phenology predictions (an average decrease in accuracy of 2·9 days was observed).

The results suggest that distribution data are a potentially useful resource for phenology research. This may allow practitioners to monitor particular regions and previously unstudied species relatively cheaply using existing mapping schemes.
UGT1A1 Gene Mutations in Pakistani Children Suffering from Inherited Nonhemolytic Unconjugated Hyperbilirubinemias
Authors: Khan Suliman , Irfan Muhammad , Sher Gulab , Zubaida Bibi , Alvi Muhammad Arshad , Yasinzai Masoom , Naeem Muhammad 
Published: August 2013

SummaryTwo inherited unconjugated hyperbilirubinemias, Crigler–Najjar syndrome and Gilbert syndrome, arise due to deficiency of UGT1A1 enzyme activity. Crigler–Najjar syndrome type 1 (CN1) lies at the extreme severe end of the spectrum of UGT1A1 activity characterized by complete absence, followed by the less severe Crigler–Najjar syndrome type 2 (CN2). Gilbert syndrome is the mild form having only partial loss of UGT1A1 activity. The present study aimed to identify molecular genetic defects underlying unconjugated hyperbilirubinemias in children from six consanguineous Pakistani families. The patients were clinically diagnosed by exclusion of other unconjugated hyperbilirubinemias. Differential diagnosis of CN1 and CN2 was made on the basis of patient's response to phenobarbitone. The promoter region, coding exons, and adjacent splice sites of the UGT1A1 gene were PCR amplified from genomic DNA of all patients and their families, and were sequenced. DNA sequence analysis identified five different homozygous mutations: two novel missense mutations p.Y230C (proband A) and p.D36N (proband B), a 4‐bp insertion c.622–625dupCAGC/p.Q208QfsX50 (probands C and E), a nonsense mutation p.R341X (proband D), and a TA insertion A(TA)7TAA in the promoter region (proband F). The present study extends the spectrum of UGT1A1 gene mutations and may be helpful in the diagnosis of Crigler–Najjar syndrome and Gilbert syndrome.
The GPCR, class C, group 6, subtype A (GPRC6A) receptor: from cloning to physiological function
Authors: Clemmensen C , Smajilovic S , Wellendorph P , Bräuner‐Osborne H 
Published: August 2013

GPRC6A (GPCR, class C, group 6, subtype A) is a class C GPCR that has been cloned from human, mouse and rat. Several groups have shown that the receptor is activated by a range of basic and small aliphatic L‐α‐amino acids of which L‐arginine, L‐lysine and L‐ornithine are the most potent compounds with EC50 values in the mid‐micromolar range. In addition, several groups have shown that the receptor is either directly activated or positively modulated by divalent cations such as Ca2+ albeit in concentrations above 5 mM, which is above the physiological concentration in most tissues. More recently, the peptide osteocalcin and the steroid testosterone have also been suggested to be endogenous GPRC6A agonists. The receptor is widely expressed in all three species which, along with the omnipresence of the amino acids and divalent cation ligands, suggest that the receptor could be involved in a broad range of physiological functions. So far, this has mainly been addressed by analyses of genetically modified mice where the GPRC6A receptor has been ablated. Although there has been some discrepancies among results reported from different groups, there is increasing evidence that the receptor is involved in regulation of inflammation, metabolism and endocrine functions. GPRC6A could thus be an interesting target for new drugs in these therapeutic areas.Linked ArticlesThis article is part of a themed section on Molecular Pharmacology of GPCRs.

Representational Constraints on Language Development: Thinking and Learning About Absent Things
Authors: Ganea Patricia A. , Saylor Megan M. 
Published: August 2013

AbstractIn this article, we illustrate the role that representational strength plays in infants' ability to communicate and learn about absent things. When understanding speech about things that are absent, infants retrieve the representation of the referent from long‐term memory upon hearing its name, and maintain that representation in working memory to plan an action toward the object or to manipulate the representation on the basis of new information. Strong representations of referents better support retrieval and maintenance operations than weak representations.
