Impact of volatility and equity market uncertainty on herd behaviour: evidence from UK REITs
Authors: Akinsomi Omokolade , Coskun Yener , Gupta Rangan , Lau Chi Keung Marco 
Published: July 2018

PurposeThis paper aims to examine herding behaviour among investors and traders in UK-listed Real Estate Investment Trusts (REITs) within three market regimes (low, high and extreme volatility periods) from the period June 2004 to April 2016.Design/methodology/approachObservations of investors in 36 REITs that trade on the London Stock Exchange as at April 2016 were used to analyse herding behaviour among investors and traders of shares of UK REITs, using a Markov regime-switching model.FindingsAlthough a static herding model rejects the existence of herding in REITs markets, estimates from the regime-switching model reveal substantial evidence of herding behaviour within the low volatility regime. Most interestingly, the authors observed a shift from anti-herding behaviour within the high volatility regime to herding behaviour within the low volatility regime, with this having been caused by the FTSE 100 Volatility Index (UK VIX).Originality/valueThe results have various implications for decisions regarding asset allocation, diversification and value management within UK REITs. Market participants and analysts may consider that collective movements and market sentiment/psychology are determinative factors of risk-return in UK REITs. In addition, general uncertainty in the equity market, proxied by the impact of the UK VIX, may also provide a signal for increasing herding-related risks among UK REITs.
Pricing to market
Authors: French Nick , Gabrielli Laura 
Published: July 2018

Purpose
Since the global financial economic crisis hit the world markets in 2007/2008, the role of property valuation has been under greater and greater scrutiny. The process of valuation and its quality assurance has been addressed by the higher prominence of the International Valuation Standards Council (IVSC). This is a significant initiative worldwide. However, there has been little written on the appropriate use of valuation approaches and methods in market valuations. There is now a hierarchy of valuation definitions. In order, there are valuation approaches, valuation methods and, as a subset of the methods, techniques or models. The purpose of this paper is to look at the importance of identifying the appropriate approach to be adopted in market valuations and the methods, techniques and models that should be applied to determine market value.

Design/methodology/approach
This practice briefing is an overview of the valuation approaches, methods and models available to the valuer and comments on the appropriateness of valuation each in assessing market value.

Findings
This paper reviews the IVSC-recognised approaches and prompts the valuer to be careful with the semantics involved so that they are better placed to provide an unambiguous service to their clients.

Practical implications
The role of the valuer in practice is to identify the appropriate approach for the valuation of the subject property, choose the right method and then apply the correct mathematical model for the valuation task in hand.

Originality/value
This provides guidance on how valuations can be presented to the client in accordance with the International Valuation Standards.
Supplier relationship management for circular economy
Authors: Dubey Rameshwar , Gunasekaran Angappa , Childe Stephen J. , Papadopoulos Thanos , Helo Petri 
Published: July 2018

PurposeWith considerable international awareness of circular economy (CE), the purpose of this paper is to propose a theoretical framework, informed by institutional theory and upper echelon theory (UET), to explain how top management commitment (TMC) mediates the relationship between external pressures and supplier relationship management (SRM) practices for CE.Design/methodology/approachThe authors test the hypotheses using cross-sectional data gathered using a survey of companies involved in sustainability practices.FindingsThe results of the hierarchical regression and mediating regression analyses suggest that TMC positively mediates the effect of external institutional pressures on SRM.Originality/valueThe authors advance existing theory by integrating institutional theory and UET to explain SRM practices in sustainable supply networks. Furthermore, the authors offer guidance to managers who would like to engage in leveraging SRM in sustainable supply networks and outline future research directions.
Socio-influences of user generated content in emerging markets
Authors: Kumar Harish , Singh Manoj Kumar , Gupta M.P. 
Published: July 2018

Purpose
The purpose of this paper is to conceptualize the influencing characteristics of user-generated content over perceived structure of social platforms to plan various business practices to improve the social commerce activities especially in emerging markets.

Design/methodology/approach
In first step, key factors are identified from the systematic literature studies and experts’ opinion. Second, total interpretive structural modeling is used to interpret the complexity of relationships among various factors. Further, fuzzy-MICMAC analysis is used to determine the most driving factors to improve the social commerce.

Findings
The study illustrates hierarchical relationships that can help policy designers, business leaders and decision makers to gain maximum benefits of mining the user-generated content to implement the people-oriented changes to improve economic capability of a country.

Research limitations/implications
The applicability of the study findings can be deployed mostly in emerging economies. The study has not considered the data security, cyberbullying, authenticity and reliability of shared content spread virally over social sites.

Practical implications
The paper will assist policy makers, business planners and solution providers to give importance to public-led influencing patterns to offer business solutions based on people demand and choices.

Social implications
The customers’ engagement, sharing reviews, getting suggestions from other people and finding new trends through user-generated content would enable higher social commerce activities.

Originality/value
The paper develops hierarchical relationships to represent the advancements in business and marketing activities based on influencing patterns and behavior of users over social sites.
Unlocking customer accounting’s potential: a service-dominant logic approach
Authors: Ng Frederick , Wood Zack 
Published: July 2018

Purpose
This paper aims to problematise critiques raised against customer accounting’s numeric focus, which risks controlling and simplifying customers rather than facilitating closer engagement. This analysis suggests ways to better account for what it is that customers buy, why they do so and how to better serve them.

Design/methodology/approach
Service-dominant logic (SDL) is a marketing ideology that recognises the active role of customers in value creation. Seven customer accounting techniques are appraised against SDL principles to identify strengths and shortfalls in logic and application.

Findings
Customer accounting techniques align with SDL’s beneficiary-oriented and relational view of customers. Weaker alignment is found regarding a focus on outputs rather than outcomes, silence about the customer’s role in co-creating value and failure to recognise contextual circumstances.

Research limitations/implications
The analysis uses prototypical descriptions of customer accounting techniques. Actual applications could offset weaknesses or raise other shortfalls.

Practical implications
For each area of SDL, the authors suggest avenues for integrating SDL into customer accounting using related literature and building on concepts within customer accounting techniques.

Originality/value
SDL contrasts with the traditional, goods-dominant logic that underscores much of accounting. SDL is used to critically and constructively evaluate customer accounting techniques.
Is bigger better? An analysis of economies of scale and market power in police departments
Authors: Fegley Tate , Growette Bostaph Lisa 
Published: July 2018

Purpose
The purpose of this paper is to investigate whether the nature of policing services allows for economies of scale to be realized. It is also a replication of Southwick (2005).

Design/methodology/approach
This study replicates the methodology used by Southwick (2005) to estimate police production and demand in order to determine whether there are economies of scale among police departments in a western state. Southwick’s (2005) method is unique in that it incorporates measures of market power to predict police efficiency. The present study is unique in that it involves data from a low-density, low-population western state.

Findings
Southwick’s results for New York State are markedly different from the results found for Idaho, thus questioning the external validity of Southwick’s model as applied to a relatively low-population state. The findings also indicate that, controlling for relevant variables, crime in Idaho is highly correlated with population, suggesting that police departments in low density/population states would not achieve efficiency gains through consolidation.

Research limitations/implications
The implications of this study include validating police performance measures and evaluating applicability of market power to police departments.

Practical implications
No evidence was found to support the contention that consolidation of police departments results in efficiency gains.

Originality/value
This is the first study of economies of scale in policing to use data from a low-density, low-population western state.
Can higher education reduce the negative consequences of police occupational culture amongst new recruits?
Authors: Cox Carol , Kirby Stuart 
Published: July 2018

PurposeThere is considerable evidence to illustrate police occupational culture can negatively influence service delivery and organizational reform. To counteract this, and to improve professionalism, the police services of England and Wales will become a graduate profession from 2020, although little empirical evidence exists as to what impact this will have. The purpose of this paper is to examine the implications of a police degree course on its students.Design/methodology/approachInitially, a survey was conducted with 383 university students studying for criminal justice-related undergraduate degrees in a UK university. This indicated Police Foundation degree students (n=84), identified themselves as being different, and behaving differently, to other university students. To explore the reasons for this, four focus groups were conducted with this cohort, during their two-year degree programme.FindingsThe study found that the Police Foundation degree students quickly assimilated a police identity, which affected their attitudes and behavior. The process led to a strengthening of ties within their own student group, at the expense of wider student socialization.Originality/valueThe study provides new findings in relation to undergraduate students who undertake a university-based degree programme, tailored to a future police career. The results have implications for both police policy makers and those in higher education as it highlights the strength of police occupational culture and the implications for the design of future police-related degree programmes.
Institutionalization of the OECD Grand-Narrative of Inclusivity (1983-2012)
Authors: Zohar Gal 
Published: July 2018

PurposeThe purpose of this paper is to explore the emplotment of organizational grand-narratives of a leading international organization, the Organisation for Economic Co-operation and Development (OECD). The paper includes the reconstruction of the OECD’s inclusion approach as a prototype grand-narrative. Moreover, the main goal of this paper is understanding the reciprocal relationship between the organizational narratives and other organizational domains.Design/methodology/approachTo study the structural process of emploting grand-narratives, which combines reciprocal dependencies across organizational domains, I have used process tracing, content analysis and interviews methodologies, for each domain. These methodologies were monitored by quantitative and qualitative analyses of the interactions among these domains. These methods allowed me to explore the interdependencies in the discursive and non-discursive ordering of institutional memory as a means for identifying the development of organizational narratives.FindingsThe findings of this paper confirm the reciprocal dynamics among and within three core organizational domains, narratives, organizational-epistemological settings and organizational products. These domains evolve constantly and concurrently in a three-phased process where a former organizational constellation is challenged, a consolidation takes place, and a new narrative is institutionalized. The context I chose to demonstrate this dynamic is the OECD evolving interactions between innerorganizational units and the organizational products (i.e. its activation policy recommendations), of the OECD post-Cold War inclusive approach (1989–2002).Research limitations/implicationsThe importance and complexity of the OECD as a global trendsetting organization, and the findings of this single case study are significant for their implications on trends and processes found in other complex grand-narratives. The transferability of these results would require further analysis.Originality/valueThe originality of this paper is using a transnational dynamic organization such as the OECD as the organizational model for understanding how organizations undergo emplotment processes. Moreover, this article’s analytical framework provides a deeper understanding of the complex interplay between the constraining structures and micro-level interactions.
Standardization for patient safety in a hospital department: killing butterflies with a musket?
Authors: Ernst Jette , Jensen Schleiter Astrid 
Published: July 2018

Purpose
The purpose of this paper is to look at the ways in which standardization for patient safety is approached from different positions in the field, namely nurses and managers in a hospital department, the hospital management and standard inventers. We understand safety standardization and the responses to it as a strategizing process, where standards are legitimized, taken up, handled or countered.

Design/methodology/approach
Ethnographic fieldwork was conducted in a Danish hospital department. The study included observations, interviews and documents studies. The authors apply a Bourdieusian perspective, where the authors focus on the narratives told by standard inventers, managers and nurses to examine and understand their strategizing activities in relation to safety standardization. We understand strategizing as interested action emerging in the dialectics between a habitus and a position in a field.

Findings
The authors show how the standardization of work rests on the master narrative of patient safety management and how this narrative clashes with the nurses’ practical perception of good care, which rests on the counter-narrative of the clinical judgment.

Originality/value
Safety standardization in healthcare is often studied within the broader framework of performance management using functionalist outside-in and prescriptive approaches. This study contributes to this literature by approaching standardization and the responses to it as taking place in a dialectic movement between subjective shop floor experiences and wider field-level forces. Furthermore, the study contributes to the organization and management literature concerned with change and strategic action by endorsing the Bourdieusian conception of strategizing.
Indicators for monitoring biological invasions at a national level

Published: July 2018

Abstract

A major challenge for the management of biological invasions is to ensure that data and information from basic inventories and ecological research are used alongside data from the monitoring and evaluation of interventions to trigger and improve policy and management responses. To address this issue, South Africa has committed to report on the status of biological invasions and their management every 3 years.

We propose a framework of indicators for reporting on biological invasions at a country level; assess the feasibility of the indicators using South Africa as a case study; and outline steps needed for indicator development.

We argue that a national status report on biological invasions should explicitly consider indicators for pathways, species, and sites, and should report on interventions in terms of inputs, outputs, and outcomes.

We propose 20 indicators based on data currently available, as well as existing international policy initiatives. For each indicator, we have developed a factsheet that includes different hierarchical metrics (considering data availability) and provide suggestions on assigning confidence levels. We also combine these indicators into four high‐level indicators to facilitate broader reporting and describe how forecasted indicators based on the concept of invasion debt could assist with scenario planning.

We found that many of the data required for these indicators are already available in South Africa, but they have been poorly collated to date. However, data for the indicators of most direct value to policy and planning—those dealing with the impact of biological invasions and the outcome of interventions—are scarce.

Policy implications. The framework of indicators developed here, for what we believe is the first ever national‐level report on the status of biological invasions and their management, will facilitate the inclusion of biological invasions in environmental reporting at national and international levels. By identifying knowledge gaps, a status report will also focus efforts on determining the size of a country's invasion debt and what can be done to reduce it.
Extracellular aminopeptidase modulates biofilm development of Pseudomonas aeruginosa by affecting matrix exopolysaccharide and bacterial cell death
Authors: Zhao Tianhu , Zhang Yuhuan , Wu Huijun , Wang Di , Chen Yihua , Zhu Mei‐Jun , Ma Luyan Z. 
Published: July 2018

SummaryBiofilm bacteria are embedded within a self‐secreted extracellular matrix that contains a considerable amount of proteins including many extracellular enzymes. However, little is known about the roles of such enzymes in biofilm development. Here, we studied Pseudomonas aeruginosa aminopeptidase (PaAP, encoded by PA2939 that we named the gene as paaP in this study), a quorum‐sensing‐regulated enzyme and one of the most abundant extracellular proteins in the biofilm matrix of this opportunistic pathogen and environmental bacterium. We found that deletion of paaP in P. aeruginosa increased initial attachment and biofilm formation at early stages of biofilm development. After 24 h growth, loss of PaAP resulted in substantial cell death and biofilm disruption. Bacterial cell death was independent of biofilm matrix polysaccharide Psl, while biofilm disruption was due to the degradation of Psl matrix by dead‐bacteria‐released glycosyl hydrolase PslG, thereby leading to biofilm dispersion. PaAP functioned extracellularly and aminopeptidase catalytic activity was essential for its effect on biofilm development. Our data reveal an important role of extracellular aminopeptidase in biofilm development, suggesting PaAP as a therapeutic target for preventing P. aeruginosa infection and combating biofilm‐related complications.
Efficacy of combined icotinib and pemetrexed in EGFR mutant lung adenocarcinoma cell line xenografts
Authors: Cui Jiadong , Zhang Yan , Su Di , Li Tao , Li Yu 
Published: July 2018

BackgroundThe combination of EGFR tyrosine kinase inhibitors (TKIs) and chemotherapy is thought to increase treatment efficacy in non‐small‐cell lung cancer (NSCLC). This study investigated the efficacy and potential mechanisms of different combined modes of icotinib plus pemetrexed in EGFR‐mutant lung adenocarcinoma cell line xenograft models.MethodsNude mice were subcutaneously injected with EGFR‐mutant human lung adenocarcinoma cells (HCC827) and randomized into six treatment groups. Tumor xenograft volumes were monitored and recorded. Microvessel density (MVD) and proliferation and apoptosis rates were evaluated with CD34 positive cell counting, and Ki‐67 and caspase‐3 scores, respectively, and determined via immunohistochemistry. Thymidylate synthase (TS), EGFR, and downstream signaling molecule expression was detected by Western blotting.ResultsThe volume and weight of tumor xenografts in the sequential pemetrexed followed by icotinib (Pem‐Ico) group and the concurrent icotinib and pemetrexed (Ico + Pem) group were significantly smaller than those in the control, pemetrexed (Pem), icotinib (Ico), and sequential icotinib followed by pemetrexed (Ico‐Pem) groups. Compared to other groups, a decrease in the MVD and proliferation rate and an increase in the apoptosis rate were observed in the Pem‐Ico and Ico + Pem groups. TS expression and EGFR, AKT, and MAPK phosphorylation were significantly reduced in the Pem‐Ico or Ico + Pem groups.ConclusionsPem‐Ico had additive antitumor activity in vivo, similar to Ico + Pem, both of which are suggested as potentially optimized strategies for treating EGFR‐mutant lung adenocarcinoma.
Trap nests for bees and wasps to analyse trophic interactions in changing environments—A systematic overview and user guide
Authors: Staab Michael , Pufal Gesine , Tscharntke Teja , Klein Alexandra‐Maria 
Published: July 2018

Abstract

Trap nests are artificially made nesting resources for solitary cavity‐nesting bees and wasps and allow easy quantification of multiple trophic interactions between bees, wasps, their food objects and natural enemies.

We synthesized all trap nest studies available in the ISI Web of Science™ to provide a comprehensive overview of trap nest research and identify common practical challenges and promising future research directions.

Trap nests have been used on all continents and across climate zones and publication numbers have increased exponentially since the first studies in the 1950s. Originally used for detailed exploratory natural history observations, trap nests are now also an established method in hypothesis‐driven ecology and to assess environmental changes. We identify the potential of trap nests for environmental monitoring by assessing trophic interaction networks of the groups involved. While pollen collection by bees or prey hunting by wasps has often been addressed, and interactions with natural enemies were included in almost half of all publications, surprisingly few studies have quantified trophic interaction networks in response to natural and anthropogenic environmental changes.

By simultaneously revealing a multitude of trophic interactions, trap nests have the potential to broaden our understanding how species interaction networks are influenced by manifold environmental changes, which are pressing topics in ecological research. To foster the use of trap nests in future studies, we identify common challenges and offer guidance on practical solutions.
