Asymmetric return response to expected risk: policy implications
Authors: Dicle Mehmet F. , Reed Kendra 
Published: June 2019

Purpose
As investors’ fear has an impact on their risk-return tradeoff, this fear leaves markets susceptible to sudden and large fluctuations. The purpose of this study is to suggest regulators to amend their precautionary methods to recognize the difference in investor behavior for high-risk periods versus low-risk periods.

Design/methodology/approach
The authors empirically show the difference in investor response to changes in expected risk as a function of level of risk. They then show different return patterns for high-risk and low-risk days. Their approach is implemented to evaluate whether investors’ reaction is the same to changes in risk during high-risk versus low-risk periods.

Findings
The results indicate that the negative return response to incremental increases in risk is significantly higher for periods of high versus low expected risk, with high defined as risk levels above long-run normal.

Research limitations/implications
Investors’ increased response to changes in risk exposes financial markets to higher likelihood of sudden and larger fluctuations during high-risk periods. Regulator-imposed circuit breakers are designed to protect markets against such market crashes. However, circuit breakers are not designed to account for investor behavior changes. The results show that circuit breakers should be different for high- versus low-risk periods.

Practical implications
A circuit breaker that is designed to protect investors against large drops should be amended to have a lower threshold during high-risk periods.

Originality/value
The contribution is, to the authors’ knowledge, the first research effort to evaluate the effects of differences in investor behavior on investor reactions and regulator imposed fail-safes. During the times of extreme market risk, the proposed changes may enable circuit breakers function their intended purposes.
Regulating European financial markets between crisis and Brexit
Authors: Schemmel Jakob 
Published: June 2019

Purpose
This paper aims to demonstrate how the European regulatory structure of the financial markets has changed after the financial crisis. Drawing from these findings, it discusses how the regulatory system might change and be adapted to a post-Brexit financial market.

Design/methodology/approach
The paper takes a systematic/legal approach. First, it analyses the recent reform against the background of European law and corresponding research. In a second step, it discusses the implications of Brexit by examining policy and legal contributions.

Findings
The changes to the European regulatory and supervisory structure of the financial markets have proven to be a pacemaker for European administrative and treaty law. Long-standing principles have fundamentally changed. Brexit, on the other hand, even though equally severe might not lead to similar results.

Practical implications
The paper proposes a limited reform to the existing regulatory structure to consolidate developments, ease constitutional frictions and enable the regulatory authorities to react quickly to volatile markets via rule making.

Originality/value
The paper draws attention to an almost unnoticed development in European law. It also illustrates the effects of Brexit on the European financial markets.
Average scores integration in official star rating scheme
Authors: Mellinas Juan Pedro , Reino Sofia 
Published: June 2019

Purpose
Evidence suggests that electronic word-of-mouth (eWOM) plays a highly influential role in decision-making when booking hotel rooms. The number of online sources where consumers can obtain information on hotel ratings provided has grown exponentially. Hence, a number of companies have developed average scores to summarize this information and to make it more easily available to consumers. Furthermore, official star rating schemes are starting to provide these commercially developed average scores to complement the information their schemes offer. The purpose of this paper is to examine the robustness of these systems.

Design/methodology/approach
Average scores from different systems, and the scores provided by one rating site were collected for 200 hotels and compared.

Findings
Findings suggested important differences in the ratings and assigned descriptive word across websites.

Research limitations/implications
The results imply that the application of average scores by official organizations is not legitimate and identifies a research gap in the area of consumer and star rating standardization.

Originality/value
The paper is of value to the industry and academia related to the examination of rating scales adopted by major online review tourism providers. Evidence of malpractice has been identified and the adoption of this type of scales by official star rating schemes is questioned.
Does the integration of response services lead to meaningful change in healthcare activity? A case study evaluation
Authors: Hinde Sebastian , Setters Jo , Bojke Laura , Hex Nick , Richardson Gerry 
Published: June 2019

Purpose
The aim of the NHS England Vanguards of new care models was to improve healthcare provision and integration through the coordination of services, seeking to deliver the Five Year Forward View. The purpose of this paper is to report on an extensive analysis of one of the Vanguard programmes, exploring whether the implemented integrated response service (IRS) based in Harrogate, England, resulted in any meaningful change in secondary healthcare activity.

Design/methodology/approach
The authors used an interrupted time series framework applied to aggregate secondary care data, specifically emergency attendances for patients 65+, emergency bed days for all adults and non-elective admissions for 65+. Synthetic and geographic comparator data were employed to inform additional scenario analyses.

Findings
The majority of the analyses conducted found no statistically significant effect of the IRS team in either direction, suggesting that there was no change in the metrics that could be separated from natural variation. The data correlated with the findings of a qualitative analysis and challenges faced in staffing the team towards the end of the analysis period and the eventual disbanding of the IRS.

Research limitations/implications
The analysis was partially hampered by data access challenges, limited to poorly specified aggregate secondary care data, and a poorly specified intervention. Furthermore, the follow-up period was limited by the disbanding of the service.

Originality/value
This analysis indicates that the Harrogate-based IRS team is unlikely to have delivered any sustained quantifiable impact on the intended secondary care outcomes. While this does not necessarily demonstrate a failure of the core principle behind the drive for integrated care, it is an important exploration of the challenges of evaluating such a service.

Authors: Van Gasse Roos , Lesterhuis Marije , Verhavert San , Bouwer Renske , Vanhoof Jan , Van Petegem Peter , De Maeyer Sven 
Published: June 2019

PurposeThe Flemish Examination Centre designed an intervention to establish a professional learning community on the topic of writing assessment. The purpose of this paper is to investigate the effects of this intervention and explain how this intervention succeeded in establishing a professional learning community.Design/methodology/approachA mixed method design was used to answer the research questions. Quantitative analysis of comparative judgement data provided insight into the effects of the intervention. More specifically was analysed whether examiners judged more in line after the intervention. Qualitative analysis of the conversations within the intervention served to examine how interdependent examiners behaved in the professionalisation exercises and to gain insight into how a professional learning community was established.FindingsThe analysis showed that the intervention of the Flemish Examination Centre facilitated the formation of a professional learning community. This was visible in the quantitative analysis. The qualitative analysis showed that highly interdependent activities were helpful in establishing the professional learning community.Practical implicationsThis study shows that interactions of high interdependence are beneficial to facilitate professional learning communities.Originality/valueThis study shows that the assessment data can guide a well-thought out design of interventions to establish professional learning communities among assessors. Assessment data can be a guidance for supportive group constellations and discussions to improve assessment practices. The key in this regard lies in the level of interdependence that is created among participants.

Future service technologies: is service research on track with business reality?
Authors: Kunz Werner H. , Heinonen Kristina , Lemmink Jos G.A.M. 
Published: June 2019

Purpose
Service technologies are transforming the business landscape rapidly. This paper aims to explore the current scope of research in regard to emerging service technologies by comparing the content of articles in academic journals with practitioner-oriented publication outlets.

Design/methodology/approach
A total of 5,118 technology-related articles from service journals, service conferences, business journals and business magazines are analyzed. Text-mining on abstracts is used for the thematic and semantic analysis. Common research themes and their relationships are depicted in a two-dimensional structured network. Further, the sample is analyzed regarding various technologies mentioned in the Gartner Hype Cycle.

Findings
The paper reveals differences in academic and business perspectives in regard to service technologies. In comparison to business journals, scientific service research is more focused on customer-related aspects of technology. Service research has a less concrete focus on technology than in business publications. Still, service conference articles show a broader scope of emerging service technologies than academic journal articles.

Research limitations/implications
Scientific research should focus on more concrete service technologies. Business magazines serve as a good source for that and the paper identifies several promising new technology fields.

Practical implications
Although business magazines cover significantly more concrete service technologies, they miss the integrated perspective that academic articles usually offer. Academia can help business to better align concrete technologies with different internal and external perspectives.

Originality/value
This paper serves as an introduction to the special issue Future Service Technologies. Additionally, a quantitative study of recent service technology research serves as a reality check for academic researchers on business reality and provides research and practical recommendations.
Social media, diffusion of innovations, morale and digital inequality
Authors: Williams Marion Lucille , Dhoest Alexander , Saunderson Ian 
Published: June 2019

PurposeThe purpose of this paper is to explore social media usage in an academic library in South Africa and the factors influencing its use. The primary goal of the study was to examine perceptions surrounding the impact of non-adoption of social media on morale, and to explore the consequences of digital inequality.Design/methodology/approachUsing a qualitative method, in-depth interviews were conducted with a small sample comprising six key informants at the University of Limpopo Libraries.FindingsThe findings suggest that non-adoption of social media has a negative influence on morale, and that it is a very necessary tool required for interaction with students as well as promotion and marketing of the library’s resources.Research limitations/implicationsThis paper is limited to one academic library in South Africa situated in a rural area. The research suggests that more academic libraries in rural areas be studied to ascertain if geographical location and finance are barriers to social media adoption.Originality/valueThis study addresses non-adoption of social media and suggests ways to improve employee morale and retention. The research contributes to current research.
Impact of process parameters on printing resolution and dielectric properties of LTCC substrate
Authors: Jasińska Laura , Malecha Karol , Szostak Krzysztof , Słobodzian Piotr 
Published: June 2019

Purpose
The low-temperature co-fired ceramics (LTCC) microfluidic-microwave devices fabrication requires careful consideration of two main factors: the accuracy of deposition of conductive paths and the modification needed to the standard process of the LTCC technology. Neither of them are well-described in the literature.

Design/methodology/approach
The first part of this paper deals with the individual impact of screen parameters such as aperture, photosensitive emulsion thickness and mounting angle on the precision of the screen-printed conductive paths fabrication. For the quantitative analysis purposes, the design of experiment method with Taguchi orthogonal array and analysis of variance was used. The second part contains the characterization of the complex permittivity measured for different values of LTCC substrates lamination pressure.

Findings
It can be concluded, that the combination of aperture, equal to 24 µm, emulsion thickness 20 µm and mounting angle 22.5° ensures the highest quality of printed conductive metallization. Furthermore, the obtained results indicate, that the modification of the lamination pressure does not affect significantly the dielectric parameters of the LTCC substrates.

Originality/value
This paper shows two aspects of the fabrication of the microfluidic-microwave LTCC devices. First, the resolution of the applied metallization is critical in manufacturing high-frequency structures. The obtained experimental results have shown that optimal screen parameters, in terms of conductive pattern quality, can be found. Second, the received outcomes indicate that the changes in the lamination pressure do not affect significantly the electrical parameters of the substrate. Hence, this effect does not need to be taken into account.
Disposable, acetylcholinesterase-coated, screen-printed carbon electrodes for the determination of organophosphorus pesticides
Authors: Walter Piotr , Pepłowski Andrzej , Górski Łukasz , Janczak Daniel , Jakubowska Małgorzata 
Published: June 2019

Purpose
Because of the bioaccumulation effect, organophosphorus pesticides cause long-term damage to mammals, even at small concentrations. The ability to perturb the phospholipid bilayer structure as well as the overstimulation of cholinergic receptors makes them hazardous to humans. Therefore, there is a need for a quick and inexpensive detection of organophosphorus pesticides for agricultural and household use. As organophosphorus pesticides are acetylcholinesterase (AChE) inhibitors, biosensors using this mechanism hold a great promise to meet these requirements with a fraction of reagents and time used for measurement comparing to laboratory methods. This study aims to manufacture AChE-coated, screen-printed carbon electrodes applicable in such amperometric biosensors.

Design/methodology/approach
AChE enzyme, known for catalytic activity for the hydrolysis of acetylthiocholine (ATCh), could be used to obtain electrochemically active thiocholine from acetylthiocholine chloride in aqueous solutions. Using Malathion’s inhibitory effect towards AChE, pesticides’ presence can be detected by reduction of anodic oxidation peaks of thiocholine in cyclic voltammetry.

Findings
The conducted research proved that it is possible to detect pesticides using low-cost, simple-to-manufacture screen-printed graphite (GR) electrodes with an enzymatic (AChE) coating. Investigated electrodes displayed significant catalytic activity to the hydrolysis of ATCh. Owing to inhibition effect of the enzyme, amperometric response of the samples decreased in pesticide-spiked solution, allowing determination of organophosphorus pesticides.

Originality/value
Printed electronics has grown significantly in recent years as well as research focused on carbon-based nanocomposites. Yet, the utilization of carbon nanocomposites in screen-printed electronics is still considered a novelty in the market. Biosensors have proved useful not only in laboratory conditions but also in home applications, as glucometers are a superior solution for glucose determination for personal use. Although pesticides could be detected accurately using chromatography, spectroscopy, spectrometry or spectrophotometry, the market lacks low-cost, disposable solutions for pesticide detection applicable for household use. With biosensing techniques and electric paths screen-printed with GR or graphene nanocomposites, this preliminary research focuses on meeting these needs.
Managing same-side and cross-side innovations in two-sided platforms
Authors: Zhang Shaoling (Katee) , Tang Tanya (Ya) 
Published: June 2019

Purpose
Innovations are vital tasks for modern two-sided platforms to grow and avoid defunct. How these two-sided platforms innovate to impact platform performance remains virtually unexplored in literature. The purpose of this paper is to classify two types of platform innovations – same-side and cross-side – and to hypothesize that their performance is contingent on platform monetization type, growth rate and user acquisition and retention costs.

Design/methodology/approach
The authors collected news announcements of 177 same-side producer-to-producer (P-P), 216 same-side consumer-to-consumer (C-C) and 284 cross-side producer-to-consumer (P-C) innovations from 30 two-sided platforms and used event study and econometric techniques in data analysis.

Findings
The findings reveal that same-side innovations cannot sufficiently lead to an impact on platform performance, while cross-side innovations are always beneficial. Same-side P-P innovations can affect platform performance positively on consumer-monetized platforms, whereas same-side C-C innovations can only do so on producer-monetized platforms. Besides, when platforms grow rapidly (slowly), cross-side (same-side) innovations strengthen platform performance. On platforms that are subject to higher (lower) user acquisition and retention costs, only same-side (cross-side) innovations can enhance platform performance.

Practical implications
This study provides actionable insights for platform practitioners to implement proper strategies to manage same-side and cross-side innovations based on the three platform attributes of platform monetization type, growth rate and user acquisition and retention costs.

Originality/value
This study offers the first systematic and empirical investigation of two-sided platform innovations by classifying them as same-side innovations for building capability in managing users and cross-side innovations for establishing capability in managing exchange, which are the two core capabilities for two-sided platforms to avoid defunct. This study further provides a contingency framework that is unique to the two-sided platform setting to study the performance impact of these innovations.
Choosing the right approach to green your supply chains
Authors: Zhu Qinghua , Sarkis Joseph , Lai Kee-hung 
Published: June 2019

PurposeDue to the different institutional pressure such as those from market, regulations and competitors, companies have implemented green supply chain management (GSCM). Unfortunately, tens of GSCM practices exist. Whether all companies should implement GSCM and how to achieve both environmental and economic performance are still not clear for many companies. The purpose of this paper is to develop models that can be helpful for companies to identify right GSCM practices and implement GSCM effectively and efficiently.Design/methodology/approachBased on about 18 years of study on GSCM with four surveys in China in 2001, 2005, 2012 and 2016, as well as numerous site visits and interviews mainly in China but also in Japan, Germany and Canada, this paper explores institutional drivers as well as opportunities and challenges using theoretical analysis and case studies. GSCM is defined considering a product life cycle. A key three-step GSCM approach is theoretically developed considering opportunities and challenges through life cycle analysis (LCA) of a product and position of a company.FindingsAll companies should implement GSCM practices to avoid risks. To effectively implement GSCM practices, a company should understand the life cycle of its product and its position in the supply chain. A key three-step LCA-based approach can help companies to identify the critical GSCM practices.Originality/valueA key three-step LCA-based approach for GSCM implementation is originally developed based on theoretical analysis and eight years of study.
Evaluation and control process in higher education institutions: a comparative analysis
Authors: Mourato Joaquim , Patrício Maria Teresa 
Published: June 2019

Purpose
The purpose of this paper is to study the evaluation and control processes in the governance systems of higher education institutions (HEIs).

Design/methodology/approach
This study compares the performance and control processes of strategic management in four HEIs in two European countries with binary systems – Portugal and The Netherlands. Using a case study approach, the authors find that HEIs with different missions and contexts have performance and control systems that are generally indistinguishable.

Findings
The controlling strategies in the public HEIs have taken on isomorphic characteristics based on processes that enhance competition, decentralize functions and solidify performance management.

Originality/value
In this paper, the authors “unpackage” strategic management to focus on the forms of control associated with performance evaluation. Performance evaluation is central to the management process and increasingly assuming an integral part of the institution’s identity and culture.
