Published: July 2015

In a subgroup of patients with systemic sclerosis (SSc), vasospasm affecting the pulmonary circulation may contribute to worsening respiratory symptoms, including dyspnea. Noninvasive assessment of pulmonary blood flow (PBF), utilizing inert‐gas rebreathing (IGR) and dual‐energy computed‐tomography pulmonary angiography (DE‐CTPA), may be useful for identifying pulmonary vasospasm. Thirty‐one participants (22 SSc patients and 9 healthy volunteers) underwent PBF assessment with IGR and DE‐CTPA at baseline and after provocation with a cold‐air inhalation challenge (CACh). Before the study investigations, participants were assigned to subgroups: group A included SSc patients who reported increased breathlessness after exposure to cold air (n = 11), group B included SSc patients without cold‐air sensitivity (n = 11), and group C patients included the healthy volunteers. Median change in PBF from baseline was compared between groups A, B, and C after CACh. Compared with groups B and C, in group A there was a significant decline in median PBF from baseline at 10 minutes (−10%; range: −52.2% to 4.0%; P < 0.01), 20 minutes (−17.4%; −27.9% to 0.0%; P < 0.01), and 30 minutes (−8.5%; −34.4% to 2.0%; P < 0.01) after CACh. There was no significant difference in median PBF change between groups B or C at any time point and no change in pulmonary perfusion on DE‐CTPA. Reduction in pulmonary blood flow following CACh suggests that pulmonary vasospasm may be present in a subgroup of patients with SSc and may contribute to worsening dyspnea on exposure to cold.
Standardized MRI assessment of high-grade glioma response: a review of the essential elements and pitfalls of the RANO criteria
Authors: Yang Dewen 
Published: July 2015

Abstract
Accurately evaluating response in the treatment of high-grade gliomas presents considerable challenges. This review looks at the advancements made in response criteria while critically outlining remaining weaknesses, and directs our vision toward promising endpoints to come. The 2010 guidelines from the Response Assessment in Neuro-Oncology (RANO) working group have enhanced interpretation of clinical trials involving novel treatments for high-grade glioma. Yet, while the criteria are considered clinically applicable to high-grade glioma trials, as well as reasonably accurate and reproducible, RANO lacks sufficient detail for consistent implementation in certain aspects and leaves some issues from the original Macdonald guidelines unresolved. To provide the most accurate assessment of response to therapeutic intervention currently possible, it is essential that trial oncologists and radiologists not only have a solid understanding of RANO guidelines, but also proper insight into the inherent limitations of the criteria. With the expectation of improved data collection as a standard, the author anticipates that the next high-grade glioma response criteria updates will incorporate advanced MRI methods and quantitative tumor volume measurements, availing a more accurate interpretation of response in the future.
Liberalism and Literature
Authors: Goodlad Lauren M. E. 
Published: July 2015

Abstract
Liberalism in the sense of a political party did not fully exist until the years between 1847 and 1868, when the Whigs transitioned into Liberals. By the late 1850s, the Liberal Party had become a ruling force in British politics. Yet, in 1886 when the Liberals split over Irish home rule, the demise of liberalism as a coherent platform was already clear. One result of this short-lived history is a striking difference in terminology on different sides of the Atlantic. Liberal political philosophy, however, encompasses diverse referents including classical republican, Scottish Enlightenment, and German-Romantic influences. Scholars who tender specific arguments about liberalism should specify the dimensions of thinking or practice to which they refer. While ‘liberal’ discourse is, thus, contextual and multivalent, the specifically literary reference points of the term are hardly reducible to political platforms, economic doctrines, philosophical stances, or ideological agendas.
Graphene oxide chemically decorated with hybrid Ag-Ru/chitosan nanoparticles: fabrication and properties
Authors: Veerapandian Murugan , Neethirajan Suresh 
Published: July 2015

AbstractHybridization of distinct materials into a single nanoplatform is relevant to advance material’s properties for functional application such as biosensor platform. We report the synthesis and characterization of nanosheets of graphene oxide decorated with hybrid nanoparticles of silver-ruthenium bipyridine complex (Ag@[Ru(bpy)3]2+) core and chitosan shell. Hybrid nanoparticles were first obtained through a sequential wet-chemical approach usingin situreduction, electrostatic and coordination reaction. Oxygenated functional groups of graphene oxide and abundant amine groups of chitosan layer on the surface of hybrid nanoparticles allowed the functionalization reaction. Changes in intrinsic optical, chemical and structural properties of graphene oxide due to hybrid nanoparticles were studied in depth using spectroscopic techniques and an electron microscope. Electrodes modified with nanosheets of graphene oxide-hybrid nanoparticles retain the biocompatibility and displayed an amplified redox property suitable for a broad range of sensing studies.
Endocannabinoids regulate mAChR-evoked theta rhythm IPSCs in hippocampus
Authors: Tang Ai-Hui , Nagode Daniel A. , Alger Bradley E. 
Published: July 2015

AbstractExogenous cannabinoids can affect behaviorally relevant neuronal oscillations, but there is little evidence that endogenous cannabinoids (endocannabinoids, eCBs) can affect them, although it is unknown whether eCBs were generated during oscillations investigated in previous studies. In rat hippocampal slices, muscarinic receptor (mAChR) agonists stimulate the occurrence of persistent, rhythmic inhibitory post-synaptic currents (IPSC) activity and mobilize eCBs. We tested the hypothesis that mAChR-induced IPSCs would be modulated by concomitantly produced eCBs. With ionotropic glutamate receptors inhibited, mAChR agonist application triggered eCB-sensitive IPSCs that were enhanced in amplitude and frequency when a cannabinoid receptor antagonist was also present. There was also a highly significant increase in IPSC spectral power in the theta-frequency range. The data show that eCBs released by mAChRs modulate rhythmic IPSCs, and suggest that eCBs are candidate regulators of neuronal oscillations associated with eCB productionin vivo.Significance statementEndocannabinoids (eCB) are ubiquitous and powerful modulators of neuronal activity, acting in the brain mainly via cannabinoid receptors (CB1Rs) on presynaptic nerve terminals, and inhibiting neurotransmitter release. Numerous neurotransmitters, including acetylcholine (ACh), stimulate eCB release. Behaviorally important neuronal oscillations can be suppressed by exogenous cannabinoids, suggesting that eCBs could regulate oscillations normally. Such regulation, if it occurred, would represent an important new dimension of eCB actions, but to date there is little evidence that eCBs do affect neuronal oscillations. Given the enrichment of eCBs and CB1Rs in brain regions whose behavioral roles depend on neuronal oscillations, including the hippocampus, it is important to understand whether, or how, the eCBs affect rhythms.

Authors: Yang Shou-Lin , Shiu Yung-Ming , Liu Tsung-Chi 
Published: July 2015

Purpose– The purpose of this paper is to re-examine the statement of Peloza (2006) that enterprise corporate social responsibility (CSR) investment provides a protection efficacy similar to insurance.Design/methodology/approach– This study uses the event study method and data from the 2008-2010 China listed company social responsibility report and theTaiwan Economic Journal.Findings– The authors find that the insurance-like effect of CSR investment also exists in China. Both short- and long-term CSR investments of Chinese companies provide this efficacy to corporate stock prices. The authors also find diminishing marginal insurance-like effects in China market.Originality/value– The CSR investment of firms in China can reduce company stock-price loss when negative events occur. The authors therefore obtain a better understanding of the value of enterprise CSR investment.

Authors: Li Yuanhui , Ferguson John 
Published: July 2015

Purpose
– The purpose of the papers included in this issue is to cover a broad range of contemporary issues in Chinese corporate financial management and therefore provide the readers with important insights into Chinese financial markets as well as the social and economic consequences of firm behavior in the Chinese context.

Design/methodology/approach
– The first part of this issue is a special section on “Corporate Finance and Corporate Social Responsibility”, which includes three papers that explore various aspects of corporate social responsibility (CSR) from a finance perspective – including the relationship between CSR and the cost of equity, the “insurance-like effect” of CSR and competition in corporate philanthropy. The remainder of the issue includes seven further papers that cover a wide range of finance-related topics, including currency and equity, monetary policy, cross-border mergers and acquisitions, earnings management, overseas investment, information disclosure, social capital and cosmopolitanism. All of the papers included in this issue are based on empirical research that draws on primary and secondary data from Chinese financial markets and from the information disclosures of Chinese enterprises.

Findings
– The authors are confident that such in-depth discussions and analysis will help researchers and practitioners to develop a better understanding of the issues faced by Chinese managers in the context of China’s economic transformation. The findings reported in this issue will help inform and develop Chinese management theories based on a wide range of Chinese management practices.

Originality/value
– Each paper in this issue reports on different aspects of finance, reporting and management in the Chinese context, discussing findings that have both relevance and significance beyond China.
Competition in corporate philanthropic disaster giving
Authors: Gao Yongqiang , Hafsi Taïeb 
Published: July 2015

Purpose– The purpose of this study is to demonstrate how firms compete with each other in philanthropic giving in the context of a natural disaster. In particular, the authors want to investigate: Which firms act faster in disaster relief giving? How do late movers react? In the end, which firms donate most at the competitive equilibrium, first or late movers? Whether and how firm visibility will affect the relationships proposed based on the former three questions?Design/methodology/approach– The Chinese listed companies that donated to the May 12, 2008, Sichuan earthquake are taken as a sample. A negative binomial regression analysis is first conducted to identify the first movers. Then, linear regression analysis is conducted to identify the competition between first movers and late movers.Findings– The authors find that large firms and firms with a high financial performance tend to be first movers in disaster relief giving. Late movers donate amounts that are similar to those of first movers in both absolute and relative value. But first movers donate more in absolute value than late movers in the whole process of giving. Firm visibility strengthens the effect of financial performance (return on assets) on giving timing, but weakens the effect of giving timing on both first round and total giving amount.Originality/value– This study provides a dynamic theory of giving and enhances the understanding of the motives and patterns of corporate disaster relief giving. It also illustrates important insights into firms’ strategic and tactical behavior in disaster relief giving.
The strength of no tie relationship in an online recommendation
Authors: Koo Dong-Mo 
Published: July 2015

Purpose
– This paper aims to investigate whether the interactional effects of recommendation valence, tie strength and service type produce different effects on attitude and buying intention in a social networking context.

Design/methodology/approach
– A 2 × 3 × 3 between-subject experiment was carried out, involving 616 participants, and MANOVA was used to test hypotheses.

Findings
– The interactions of valence by tie strength and valence by service type affect attitude, but not intention. The review valence × tie strength × service type interaction influences both attitude and intention, and its effect on intention is fully mediated by attitude.

Research limitations/implications
– Negative recommendations for credence and experiential services communicated by individuals with no-tie relationships have a strong negative effect on attitude. However, positive recommendations from strong and weak ties for search and experience services are more influential than recommendations from no ties for credence services.

Originality/value
– The results are explained by using cue sufficiency theory, which suggests that a single extreme cue serves as a defining feature.
Unpicking motives to purchase locally-produced food: analysis of direct and moderation effects
Authors: Memery Juliet , Angell Robert , Megicks Phil , Lindgreen Adam 
Published: July 2015

Purpose
– This study aims to investigate how attributes associated with local food (intrinsic product quality; local support) motivate purchase behaviour. Previous research assumes heterogeneity in consumer motivation, but this has never been formally assessed. As such, the influence of local food attributes in motivating product use is integrated into a model in which consumer values and personal characteristics/situational variables are specified as moderators.

Design/methodology/approach
– Eight hypotheses are tested using data collected from a quota sample of respondents recruited via an online panel of 1,223 shoppers. A three-stage analysis is used using structural equation modelling. Moderation effects are tested using both latent interactions and multiple-group analysis.

Findings
– Shoppers purchase local food more frequently as a consequence of local support rather than intrinsic product quality. Unpicking these relationships reveal that local support has an amplified effect when local identity is higher, and when the shopper is either female or of an older age (55 years plus). Surprisingly, the influence of intrinsic product quality is equivalent by gender, age and location (rural/urban).

Practical implications
– Marketers promoting locally produced foods should focus on both the intrinsic attributes of local food as well as the role it plays within the local community. The latter is more likely to be successful with communications aimed at women and older consumers.

Originality/value
– With previous studies focusing on how local food attributes influence favourable consumer behaviours, the current study unpicks these relationships by examining heterogeneity in responses. This is the first study to concurrently use attributes, values and personal characteristics/situational variables in explaining shopping behaviour for local food.
B2B service brand identity and brand performance
Authors: Coleman Darren Andrew , de Chernatony Leslie , Christodoulides George 
Published: July 2015

Purpose– This paper aims to apply the business-to-business (B2B) Service Brand Identity (SBI) scale to empirically assess the influence of service brand identity on brand performance for the first time.Design/methodology/approach– Based on data collected from 421 senior marketing executives, this paper applies the B2B SBI and structural equation modeling to fulfill the above purpose.Findings– Brand personality and human resource initiatives have a positive and significant influence on brand performance. Corporate visual identity, in addition to an employee and client focus, has an insignificant impact on performance. Consistent communications have a negative and significant influence on brand performance.Research limitations/implications– Data were only collected from executives in the UK. This research would benefit from replicative studies.Practical implications– This research empirically establishes the brand management activities that drive brand performance.Originality/value– This is the first empirical study to assess the influence service brand identity has on brand performance.
Professional sales coaching: an integrative review and research agenda
Authors: Badrinarayanan Vishag , Dixon Andrea , West Vicki L , Zank Gail M 
Published: July 2015

Purpose
– The purpose of this paper is to provide an integrative review of coaching research from different contexts (e.g. athletics, executive coaching, project management and sales), delineate professional sales coaching from other developmental activities and develop a research agenda for stimulating research on professional sales coaching. Professional sales coaching is considered an important sales force developmental program by both sales practitioners and researchers. Yet, research on sales coaching remains fragmented in the extant literature.

Design/methodology/approach
– An extensive literature review of extant research and theoretical perspectives on coaching as well as insights gathered from exploratory, in-depth interviews of ten sales managers were used to develop the research agenda.

Findings
– The review and research agenda identify a number of sales coaching-related topics that warrant further research. Specifically, the research agenda addresses salesperson characteristics, sales manager and coach characteristics, selling organization characteristics, sales coaching approaches, nature and effectiveness of the sales coaching process and, finally, outcomes of sales coaching. For each topic, extant research, relevant insights from exploratory interviews and directions for future research are discussed.

Originality/value
– This paper is the first integrative review of coaching-related research in the sales literature. It offers an updated conceptualization of sales coaching and identifies opportunities for future research.
Are size-zero female models always more effective than average-sized ones?
Authors: Bian Xuemei , Wang Kai-Yu 
Published: July 2015

Purpose
– The purpose of this paper is to investigate if brand might affect consumers’ response to replacing size-zero models (SM) with average-sized models (AM) in advertising and how individuals’ psychological states might underlie consumers’ reactions.

Design/methodology/approach
– Three studies manipulating brand and model body size were conducted and advertising images to female individuals differing in self-esteem were exposed.

Findings
– This research finds that brand moderates consumers’ model evaluation. Participants evaluated AM as being more attractive than SM for new brands, whereas for well-established brands associated with SM, participants rated both AM and SM as being equally attractive. Self-esteem shapes participants’ evaluation of AM and SM. For new brands, low self-esteem individuals evaluated AM as being more attractive than SM, whereas high self-esteem individuals evaluate AM and SM as being equally attractive. The results are consistent, regardless of whether it is a luxury and a generic brand. These results emerged for both model attractiveness rating and product evaluations.

Practical implications
– A better understanding of the relative consequences of the use of AM versus SM is essential for more effective policy initiatives and better targeted marketing campaigns.

Originality/value
– Limited research has documented the possible effects of brand on individuals’ responses to AM as opposed to SM. How individuals of different psychological characteristics may react distinctively to advertisements containing AM versus stereotype SM has not yet been explored until this study. This research takes the first step to bridge these knowledge gaps by looking into how brand and perceiver psychological characteristics jointly work with model features to determine how consumers perceive the AM as opposed to SM. This study provides empirical and comparative evidence of the advantages of using AM and SM in print media.
Constituent aspects of workplace guidance in secondary VET
Authors: Swager Robert , Klarus Ruud , van Merriënboer Jeroen J. G. , Nieuwenhuis Loek F.M. 
Published: July 2015

Purpose– This paper aims to present an integrated model of workplace guidance to enhance awareness of what constitutes good guidance, to improve workplace guidance practices in vocational education and training.Design/methodology/approach– To identify constituent aspects of workplace guidance, a systematic search of Web of Science was conducted, focussing on mentoring literature, research on institutional socialization tactics and research on didactical interventions and their effects.Findings– The model interprets workplace learning as a relational and integrated process of participation, acquisition, guidance and social interaction. Psychosocial support, structure-providing interventions and didactical interventions are discussed as essential components of guidance. How these components are enacted is influenced by the characteristics of training firms and their employees’ readiness to provide guidance. This makes guidance an intrapersonal process. Workplace guidance is also an interpersonal process in which the agencies of employees mediate the relationship between guidance and interaction, and the agencies of trainees mediate the relationship between, on the one hand, participation and acquisition and, on the other hand, social interaction.Originality/value– Integrated models of what constitutes good workplace guidance are rare. To fill this gap, this paper highlights constituent aspects of workplace guidance and brings them together in an integrated model. The model can help mentors/employees choose effective interventions to improve workplace learning.
