The Impact of Financial Analyst Reports on Small Caps Prices in Italy
Authors: Guagliano Claudia , Linciano Nadia , Contento Concetta Magistro 
Published: October 2013

AbstractThis paper examines the abnormal stock returns around the publication of 1167 reports issued by 26 brokerage firms on 37 small caps admitted to listing on the Italian Stock Market from 2003 to 2011. The focus is on small caps going public because for such firms information asymmetries may be severe and, therefore, analyst reports should be particularly valuable to the market. Several hypotheses are tested. First of all, the market impact is computed for the whole sample and for each recommendation category (buy, hold and sell). The exercise is repeated by controlling for the presence of contemporaneous news; by taking into account only the initiations of coverage; by selecting only the changes in recommendations. The results obtained through a standard event study methodology show that analyst reports on small caps are informative for the market, although the price impact differs across the samples considered. For the whole sample of reports, the cumulative abnormal returns estimated over a 3‐day event window around the publication date are statistically significant for buy and hold recommendations only (+0.98 and −0.83 per cent, respectively); however, after selecting out contaminating events only buys are significant (+1.13 per cent). Also the buy recommendations included in the initiation of coverage sample turn out to convey information to the market (+1.50 per cent); the highest price impact, however, is estimated for the upgrades included in the revisions of recommendation sample (+2.19 per cent). The second result of the paper is that information leakage is not widespread, given that abnormal returns are almost never significant before the report date. Therefore on average, the timing of the market reaction to financial research dissemination does not signal tipping or selective disclosure.
Gains to Chinese Bidder Firms: Domestic vs. Foreign Acquisitions
Authors: Black Emma L. , Doukas Angelos J. , Xing Xiaofei , Guo Jie (Michael) 
Published: October 2013

AbstractThis paper examines whether foreign acquisition of Chinese firms improves share price performance relative to domestic acquisitions. The results show that foreign acquisitions are not associated with positive abnormal returns in the short‐run, but that they are so associated for domestic acquisitions. Foreign acquisitions also realise significant long‐run gains, especially when the acquiring firm is large. Specifically, we find that there is a significant, positive long‐run outperformance of 29.81% for large foreign acquisitions benchmarked against domestic ones, while large foreign acquisitions earn 22.39% in aggregate. Our evidence suggests that large Chinese acquirers gain when they expand their operations abroad, consistent with the literature on reverse internalisation.
The Squeezed Middle: An Exploration of Creativity, Conformity and Social Class on the Academic Achievement of Undergraduate Students within a UK Art School
Authors: Jackson Mark 
Published: October 2013

AbstractOver the past decade, a wealth of UK government initiatives have provided opportunities for higher education institutions to increase student numbers by engaging more with defined groups of students who do not traditionally participate in post compulsory education. Within the creative arts subjects, the success of these politically sensitive initiatives, however, also serves to highlight the growing frustrations of another group of students who show little progress in their achievement during their time at university. These students have a relatively successful school exam profile, are rarely identified as requiring any additional teaching support, maintain an excellent record of attendance and yet rarely achieve the highest assessment grades. Using data collected from a university design department over the past 5 years supported by interviews with current students, this article explores how the cultural behaviours frequently associated as advantageous to emotional welfare may become increasing problematic in an art and design education culture that celebrates creativity, risk taking and ambiguity.
Virtual Voices: Exploring Creative Practices to Support Life Skills Development among Young People Working in a Virtual World Community
Authors: Sclater Madeleine , Lally Victor 
Published: October 2013

AbstractThe dialectical relationship between social justice, active participation and the development of aesthetic sensibilities is re‐emerging as a theme among art and design educators as concerns mount for the future of art and design education in the curriculum – particularly in the UK, but also internationally. This article explores the potential of virtual worlds to support the development of young people's voices using creative practices – photography, film‐making and fashion – as the principal means of engaging young people in developing their understanding of active citizenship. The use of creative practices to support a range of wider educational aims in virtual worlds has not yet been investigated and, we contend, is an area of serious research endeavour. We report on the research of an EPSRC/ESRC‐funded project called ‘Inter‐Life’ which examined how virtual worlds could be used to support the development and acquisition of life skills to enhance the management of important life transitions. The project investigated the extent to which young people's engagement in creative practices within these environments assisted with these processes. Some implications for future research are outlined.
Art Spoken Here: Reggio Emilia for the Big Kids
Authors: Cutcher Alexandra 
Published: October 2013

AbstractDeveloping one's creative potential is a basic human right, and thus the relationship between democracy and creativity is ineffable. Reggio Emilia pedagogies recognise this intrinsically; teaching through this modality embeds deep learning and an aesthetic awareness not often evident in formal schooling, despite the overwhelming evidence regarding the value of a sustained art education. Our children are all born creative and brave, yet something happens to them as they grow – the opportunities to express themselves artistically at school become minimised, the art curriculum becomes marginalised, and our children's creative genius falls away. What would Reggio Emilia look like in the High School classroom? Imagine a curriculum where all students' creative potential was nurtured, every day. This article explores this proposition, and argues that by utilising the highly successful pedagogies of Reggio Emilia, we can attend to the fundamental right of every child to an education that nurtures their inherent creativity.
Postcode Criminals
Authors: Hiett Sandra , Kushner Joann 
Published: October 2013

AbstractPostcode Criminals was the second phase of an international participatory community arts project challenging negative stereotypes of urban youth. Concerned with the impact of zero tolerance community policing strategies in the UK and USA, artists Joann Kushner and Dread Scott developed an art‐based project with a social justice agenda. To give voice to an under‐represented group, the project invited high academic achievers with no history of criminal behaviour from economically and socially deprived urban communities to participate. Postcode Criminals focused on regions of Liverpool and New York, typically sites where community policing strategies had been in force for some time. The findings of this project reveal that relationships between young people, their communities and the police force have been damaged as a direct result of community policing strategies, despite the reported success in crime reduction figures. Fear of crime was found to be a greater problem in urban communities than crime itself. Young people's experiences of ‘ephebiphobia’, the fear of teenagers, were articulated, creating alternative, positive representations of themselves and providing a catalyst for improved community relations.

AbstractObjectivesTo evaluate the stabilizing function of atlanto‐axial ligaments in dogs.Study DesignCadaveric biomechanical study.AnimalsBeagle dog cadavers (n = 10).MethodsThe craniocervical region was collected from 10 Beagle cadavers, and the occipito‐atlanto‐axial region was prepared and freed from the surrounding muscles. Care was taken to preserve integrity of the atlantoaxial ligaments and atlantoaxial joint capsule. The atlanto‐occipital joints were blocked with 2 diverging transarticular 1.8 mm positive threaded K‐wires. Specimen extremities were embedded in polymethylmethacrylate (PMMA) and mounted on a simulator testing shear load at the atlantoaxial joint. Range of motion (ROM) and neutral zone (NZ) were determined with all ligaments intact, after cutting the apical ligament, both alar ligaments, the transverse ligaments and finally after cutting the dorsal atlantoaxial ligament.ResultsROM increased similarly and stepwise during testing. The most significant increase was observed after transection of the alar ligaments.ConclusionThe alar ligaments seem to be the most important ligamentous structures for stabilization of the atlantoaxial joint under shear load.

Published: October 2013

Molybdenum isotopes are increasingly widely applied in Earth Sciences. They are primarily used to investigate the oxygenation of Earth's ocean and atmosphere. However, more and more fields of application are being developed, such as magmatic and hydrothermal processes, planetary sciences or the tracking of environmental pollution. Here, we present a proposal for a unifying presentation of Mo isotope ratios in the studies of mass‐dependent isotope fractionation. We suggest that the δ98/95Mo of the NIST SRM 3134 be defined as +0.25‰. The rationale is that the vast majority of published data are presented relative to reference materials that are similar, but not identical, and that are all slightly lighter than NIST SRM 3134. Our proposed data presentation allows a direct first‐order comparison of almost all old data with future work while referring to an international measurement standard. In particular, canonical δ98/95Mo values such as +2.3‰ for seawater and −0.7‰ for marine Fe–Mn precipitates can be kept for discussion. As recent publications show that the ocean molybdenum isotope signature is homogeneous, the IAPSO ocean water standard or any other open ocean water sample is suggested as a secondary measurement standard, with a defined δ98/95Mo value of +2.34 ± 0.10‰ (2s).
Comparison of Drought Tolerance of Maize, Sweet Sorghum and Sorghum‐Sudangrass Hybrids
Authors: Schittenhelm S. , Schroetter S. 
Published: October 2013

AbstractIn drought‐prone environments, sweet sorghum and sorghum‐sudangrass hybrids are considered worthy alternatives to maize for biogas production. The biomass productivity of the three crops was compared by growing them side‐by‐side in a rain‐out shelter under different levels of plant available soil water (PASW) during the growing periods of 2008 to 2010 at Braunschweig, Germany. All crops were established under high levels of soil water. Thereafter, the crops either remained at the wet level (60–80 % PASW) or were subjected to moderate (40–50 % PASW) and severe drought stress (15–25 % PASW). While the above‐ground dry weight (ADW) of sweet sorghum and maize was insignificantly different under well‐watered conditions, sweet sorghum under severe drought stress produced 27 % more ADW than maize. The ADW of sorghum‐sudangrass hybrids significantly lagged behind sweet sorghum at all levels of water supply. The three crops differed markedly in their susceptibility to water shortage. Severe drought stress reduced the ADW of maize by 51 %, but only by 37 % for sweet sorghum and 35 % for sorghum‐sudangrass hybrids. The post‐harvest root dry weight (RDW) in the 0–100 cm soil layer for maize, sweet sorghum and sorghum‐sudangrass hybrids averaged 4.4, 6.1 and 2.9 t ha−1 under wet and 1.9, 5.7 and 2.4 t ha−1 under severe drought stress. Under these most dry conditions, the sorghum crops had relatively higher RDW and root length density (RLD) in the deeper soil layers than maize. The subsoil RDW proportion (20–100 vs. 0–20 cm) for maize, sweet sorghum and sorghum‐sudangrass hybrids amounted to 6 %, 10 % and 20 %. The higher ADM of sweet sorghum compared with maize under dry conditions is most likely attributable to the deep root penetration and high proportion of roots in the subsoil, which confers the sorghum crop a high water uptake capacity.
Temperature Gradient Introduced Ferroelectric Self‐Poling in BiFeO3 Ceramics

Published: October 2013

The as‐prepared BiFeO3 ceramic shows a piezoelectric d33 coefficient of −14 pC/N, that is, an obvious ferroelectric self‐poling phenomenon. The temperature gradient between the two surfaces of BiFeO3 ceramic was intentionally enlarged when BiFeO3 was prepared with a rapid liquid sintering method. This temperature gradient and the corresponding thermal strain can introduce defect dipoles through separating bismuth vacancies from oxygen vacancies. A mass of these dipoles introduce a macroscopic internal electric field (Ein) which downward poles BiFeO3 ceramic during its cooling down process. As expected, an Ein of >10 kV/cm is confirmed by the asymmetrical polarization/strain versus electric field curves.
Nanoscaled Interface Between Microgold Particles and Biphase Glass‐Ceramic Matrix
Authors: Yi Wei , Hu Xiaozhi , Ichim Paul , Sun Xudong 
Published: October 2013

This article presents a detailed study on the nanoscaled interface between microelongated gold particles (GP) and biphase leucite/feldspar glass‐ceramic matrix. The glass‐ceramic composite with a nonuniform GP distribution was processed through hot‐pressing under vacuum using a commercial dental ceramic furnace for glass‐ceramic dental crown manufacturing. Heat treatments at 900°C, 1100°C, and 1300°C were conducted, and microstructural features along the interface were used to verify the chemical reactions between GP and glass‐ceramic matrix. It was observed that the amorphous glass‐ceramic matrix had nanoscaled biphase structures, and the distributed nanoscaled amorphous leucite phase was attracted to GP during hot‐pressing, and was more reactive with GP than the feldspar phase. The thickness of the interfacial phase formed through chemical reactions between GP and glass‐ceramic matrix is around 30 nm. The chemically bonded interface has contributed significantly toward the substantial improvements in both strength and toughness of the GP‐reinforced glass‐ceramic matrix composite. Characterization techniques, including X‐ray diffraction and field‐emission scanning electron Microscopy, incorporating X‐ray microanalysis using energy dispersive spectrometry, have been employed in this study.

Published: October 2013

Acmite (NaFeSi2O6) films were formed on steel coupons via solvothermal reaction of silica, sodium hydroxide, and 1, 4‐butanediol in an autoclave under autogenous pressure. Systematic variation in processing variables led to homogenous coatings comprised of pinacoidal acmite grains with an average grain size of ~33 μm. The coatings were produced on the steel coupons from reactant conditions of 0.635 m SiO2, 2.546 m NaOH, and 3.087 m 1,4‐butanediol for 72 h at 240°C.
Direct Formation and Luminescence Properties of Yttrium Niobate YNbO4 Nanocrystals via Hydrothermal Method
Authors: Hirano Masanori , Dozono Hayato 
Published: October 2013

Yttrium niobate YNbO4 nanocrystals with ellipsoidal morphology were directly formed from the precursor solution mixtures of YCl3 and NbCl5 under weakly basic conditions in the presence of aqueous ammonia by hydrothermal method. The hydrothermal treatment at 180°C for 5 h was necessary to obtain nanocrystals (18 nm) with sufficient crystallinity. The optical band gap of the as‐prepared samples was 3.6 eV. The as‐prepared YNbO4 nanocrystals showed UV‐blue and broadband emission centered at 405 nm under excitation at 235 nm, which was due to the blue recombination luminescence, associated with charge‐transfer transitions involving the tetrahedral NbO4 group. The emission intensity increased with increased hydrothermal treatment temperature. The photoluminescence intensity of the YNbO4 was extremely improved via heating above 1000°C in air, which was accompanied by the increase in the optical band gap from 3.6 to 4.0 eV. By heat treatment at 1300°C, the intensity of the UV‐blue and broadband emission (with maximum at 400 nm) for the YNbO4 became more than 22.5 times as strong as that before heat treatment.

AbstractAimTo evaluate a psychoeducational intervention for patients with advanced cancer who have cachexia and their lay carers.BackgroundCachexia is a frequent and devastating syndrome of advanced cancer. It has an impact on patients biologically, psychologically and socially and has profound impact on their lay carers. Prior research has predominately focused on the biological components of cachexia and associated potential treatment modalities. At present, there is no standardized supportive healthcare intervention in current practice that targets the psychosocial impact of this syndrome.DesignA pragmatic multicentre randomized controlled trial.MethodsPatient/carer dyads (n = 200) will be recruited into a randomized controlled trial of a DVD intervention for cachexia management. The sample will be recruited from two urban hospices in the UK. The primary outcome measure will be the General Health Questionnaire‐12. Additional questionnaires focusing on distress, readiness to give care and coping skills will be used as secondary outcome measures. In addition, lay carers in the intervention group will be asked to participate in semi‐structured interviews following the death of their loved one. Both Office for Research Ethics Committee approval and local governance approval at both hospices have been obtained as of February 2013.DiscussionThis is the first time that a psychoeducational DVD has been tested in a randomized controlled trial in this population. Dissemination of findings will make a significant contribution to international knowledge and understanding in this area. Findings will inform education, practice and policy.
Navigating conflict and power at work: the effects of power and interdependence asymmetries on conflict in organizations
Authors: Coleman Peter T. , Kugler Katharina G. , Mitchinson Adam , Foster Chris 
Published: October 2013

AbstractMany of the most difficult conflicts people face at work are up and down; with bosses, supervisors, and important clients, or with direct reports, staff, or other employees who differ from them in terms of their power and interests. However, much of the research on power differences and conflict tends to be piecemeal, decontextualized, and focused on negative consequences. This paper presents 2 studies that investigated a new situated model of conflict and power at work. They build on classic areas of research on social conflict, power, and interdependence; and integrate them into a coherent framework for organizational conflict research. The study methods and findings are presented, and their implications for research on work conflict are discussed.
Disaster threat and justice sensitivity: a terror management perspective
Authors: Kastenmüller Andreas , Greitemeyer Tobias , Hindocha Neil , Tattersall Andrew J. , Fischer Peter 
Published: October 2013

AbstractBased on terror management theory, we tested the idea that reminders of death strengthen justice sensitivity. In Study 1, we exposed participants to three different kinds of death‐related pictures (terrorism vs. natural disasters vs. graveyards) or neutral pictures. The results showed that death‐related visual material led to more justice sensitivity from three perspectives (victim, observer, and perpetrator) than neutral visual material. Likewise, Study 2 indicated that fake newspaper articles claiming that the likelihood of terrorism is very high (vs. low) strengthened these three justice sensitivity types. Theoretical and practical implications are discussed.
Investigating the motivations underlying harmful social behaviors and the motivational nature of social norms
Authors: Amiot Catherine E. , Sansfaçon Sophie , Louis Winnifred R. 
Published: October 2013

AbstractThe present research applies a self‐determination theory framework to capture the broad spectrum of reasons why individuals engage in harmful normative behaviors. This correlational study (N = 242) focused on harmful behaviors that were either supported by one's in‐group or not. Participants whose in‐group encourages them to engage in a harmful behavior reported stronger motivation, both self‐determined and non‐self‐determined. Perceiving strong in‐group norms in favor of these behaviors was associated positively with the non‐self‐determined motivation pertaining to introjected regulation. The more participantsagreedwith an in‐group norm in favor of a harmful behavior, the stronger their self‐determination for engaging in this behavior. Results are discussed in light of self‐determination theory, normative models of social influence, and intergroup theories.
