Moderating and mediating roles of environmental concern and ecotourism experience for revisit intention
Authors: Huang Yung-Chuan , Liu Chih-Hsing Sam 
Published: May 2017

Purpose
This study aims to provide novel insights via a joint investigation of the mediating role of environmental concern and ecotourism experiences. It further explores environmental concern and image as moderators of the association between tourists’ ecotourism experience and revisit intention.

Design/methodology/approach
The study used a three-way framework which provided novelty ways of combined moderation-mediation tests on a sample of 474 foreign tourists.

Findings
Results show that environmental concern and ecotourism experience mediated the relationships between motivation and revisit intention. The moderating test shows that foreign tourists’ revisit intention and ecotourism experience are highest when environmental concern and image are high.

Practical implications
Results of this study suggest that it may be beneficial to relate resources of tourism’s organization to prepare for potential sustainable requirements and/or to assist tourists to develop positive pro-environment attitudes (such as inspire tourists’ sense of social responsibility to improve environmental quality), which could possibly improve the feelings about the natural environment as serving the public good and may raise concern about environmental protection reasonability for tourists.

Originality/value
This research is the first comprehensive examination of foreign tourists’ pro-environment attitudes and conducts three-way interaction between tourists’ ecotourism experience, image and environmental concern, which may provide a benchmark for future studies.
A special feature of corporate income taxation in Portugal: the autonomous taxation of expenses
Authors: Dinis Ana , Martins António , Lopes Cidália Maria 
Published: May 2017

PurposeThe purpose of this paper is to discuss the following research questions: Is the Portuguese corporate income tax (CIT) losing its internal consistency by extending the autonomous taxation of expenses (ATE)? Are receipts derived from autonomous taxes so relevant that what began as an exception is gradually becoming a permanent feature of the income tax? Given the constitutional principle that corporate taxation should be fundamentally based on income, is the taxation of expenses unconstitutional? Is Portugal an international outlier, in applying this type of taxation to corporate expenses?
Design/methodology/approachThe methodology used in the paper is a blend of legal research method and case study analysis. The interpretation of legal texts and the ratio legis discussion (hermeneutical side), the evaluation of advantages and disadvantages of autonomous taxes (argumentative approach) and the use of aggregate data to gauge an impression of autonomous taxes’ impact on global tax receipts (empirical side) will, jointly, be used to analyse the topic. Autonomous taxation is a case study on how a (albeit distortive) solution is being applied in an European Union (EU) country to significantly enhance corporate-related tax revenue.
FindingsThe authors conclude that autonomous taxation is a relevant source of revenue and its elimination is not foreseeable, at least in the medium term. Moreover, the extension of the tax base is gradually transforming CIT in a kind of dual tax, by charging profits and some expenses. The Constitutional Court, stressing the equity principle, has not ruled autonomous taxation unconstitutional, invoking usefulness against tax evasion. Finally, with the exception of some Portuguese-speaking countries, no other comparable international experience is observed.
Practical implicationsThe autonomous taxes (ATE) and its progressive enlargement imply, on the one hand, that the CIT has been slowly, but inexorably, losing its sole purpose of taxing profits, and imposing a tax penalty on an increasing set of accounting expenses. On the other hand, the growing number of expenses subjected to taxation leads some authors to ponder if the Portuguese tax regime is losing attractiveness. By increasing ATE’s scope, the effective rate tends to move upwards, countering reductions in the statutory rate. Finally, tax law will increasingly influence managers’ daily decisions, given the set of expenses targeted by autonomous taxes.
Originality/valueTaking into account the aim of this study, the discussion of a Portuguese particular feature of corporate taxation can highlight useful policy points to a broader audience. Many Organization for Economic Cooperation and Development (OECD) countries face a dire situation in public finances. Therefore, given the pressure to increase tax receipts, the ATE can be a case study on how a (albeit distortive) solution is being applied in an EU country to significantly enhance corporate-related tax revenue.
Trust-building mechanisms in a coopetition relationship: a case study design
Authors: de Araujo Diana von Borell , Franco Mário 
Published: May 2017

PurposeFrom social network theory, this study aims to understand how trust is built in a coopetition relationship.Design/methodology/approachA case study of a qualitative nature was carried out using several semi-structured interviews with managers of two Brazilian firms involved in a dyadic coopetition relationship.FindingsBased on the empirical evidence, five categories/themes resulted for understanding trust-building mechanisms: mutual dependence, previous experience and reputation, awareness of the risks of opportunistic behaviour, contractual agreement and dynamic process. The juridical sphere, contractual agreement, was the only one identified in the study where firm representatives presented discordant positions, referring specifically to contractual relations of the terms of the agreement.Practical implicationsThe results of this study provide some suggestions for managers. First, before beginning interaction in a coopetition relationship, it is necessary to assess whether the coopetition relation meets the required conditions for interaction to take place. Second, the results suggest that firms should make provision against members of both organizations making the relationship vulnerable to acts of opportunism.Originality/valueThis case study is innovative because it reveals manifestations that could help to enhance knowledge of how organizations build trust in dyadic coopetition relationships.

Published: May 2017

PurposeAssistive living technologies provide support for specific activities, transforming a home into a smart home. The purpose of this paper is to present how to design, implement, deploy and install a personalized ambient support system for the elderly suffering from Alzheimer’s disease (AD) and nighttime wandering.Design/methodology/approachThe intervention presented in this paper proceeds in two phases. During the monitoring phase, the system determines the profile of the person with AD, based on nighttime routines. Data are gathered from sensors dispatched in the smart home, coupled with physiological data obtained from sensors worn by the person. Data are then classified to determine engine rules that will provide assistance to the resident to satisfy their needs. During the second phase, smart assistance is provided to the person via environmental cues by triggering rules based on the person’s habits and the activities occurring during night.FindingsThe paper develops the architecture of a non-intrusive system that integrates heterogeneous technologies to provide a calm environment during night and limit wandering periods.Practical implicationsThe goal is to help people age well at home as long as possible and recover a regular circadian cycle while providing more comfort to the caregiver.Originality/valueThe system presented in this paper offers a calm and personalized environment with music and visual icons to soothe persons with AD and encourage them to go back to bed. It is installed at the patient’s home using wireless technologies.
Automatic fight detection in surveillance videos
Authors: Fu Eugene Yujun , Leong Hong Va , Ngai Grace , Chan Stephen C.F. 
Published: May 2017

Purpose
Social signal processing under affective computing aims at recognizing and extracting useful human social interaction patterns. Fight is a common social interaction in real life. A fight detection system finds wide applications. This paper aims to detect fights in a natural and low-cost manner.

Design/methodology/approach
Research works on fight detection are often based on visual features, demanding substantive computation and good video quality. In this paper, the authors propose an approach to detect fight events through motion analysis. Most existing works evaluated their algorithms on public data sets manifesting simulated fights, where the fights are acted out by actors. To evaluate real fights, the authors collected videos involving real fights to form a data set. Based on the two types of data sets, the authors evaluated the performance of their motion signal analysis algorithm, which was then compared with the state-of-the-art approach based on MoSIFT descriptors with Bag-of-Words mechanism, and basic motion signal analysis with Bag-of-Words.

Findings
The experimental results indicate that the proposed approach accurately detects fights in real scenarios and performs better than the MoSIFT approach.

Originality/value
By collecting and annotating real surveillance videos containing real fight events and augmenting with well-known data sets, the authors proposed, implemented and evaluated a low computation approach, comparing it with the state-of-the-art approach. The authors uncovered some fundamental differences between real and simulated fights and initiated a new study in discriminating real against simulated fight events, with very good performance.
A passive method for privacy protection in the perceptual layer of IoTs
Authors: Li Xiaoyu , Yoshie Osamu , Huang Daoping 
Published: May 2017

Purpose
The purpose of this paper is to detect the existence of unknown wireless devices which could result negative means to the privacy. The perceptual layer of internet of things (IoTs) suffers the most significant privacy disclosing because of limited hardware resources, huge quantity and wide varieties of sensing equipment. Determining whether there are unknown wireless devices in the communicating environment is an effective method to implement the privacy protection for the perceptual layer of IoTs.

Design/methodology/approach
The authors use horizontal hierarchy slicing (HHS) algorithm to extract the morphology feature of signals. Meanwhile, partitioning around medoids algorithm is used to cluster the HHS curves and agglomerative hierarchical clustering algorithm is utilized to distinguish final results. Link quality indicator (LQI) data are chosen as the network parameters in this research.

Findings
Nowadays data encryption and anonymization are the most common methods to protect private information for the perceptual layer of IoTs. However, these efforts are ineffective to avoid privacy disclosure if the communication environment exists unknown wireless nodes which could be malicious devices. How to detect these unknown wireless devices in the communication environment is a valuable topic in the further research.

Originality/value
The authors derive an innovative and passive unknown wireless devices detection method based on the mathematical morphology and machine learning algorithms to detect the existence of unknown wireless devices which could result negative means to the privacy. The simulation results show their effectiveness in privacy protection.
Finance managers in family firms: an upper-echelons view
Authors: Hiebl Martin R.W. 
Published: May 2017

Purpose
Informed by upper echelons theory, the purpose of this paper is to synthesize the current knowledge on finance managers in family firms and to suggest valuable future research avenues.

Design/methodology/approach
The paper is organized as a theory-informed literature review. Based on a keyword search in electronic databases, 17 journal articles that deal with finance managers in family firms were identified. In light of upper echelons theory, the results of these articles were analyzed and future research needs were identified.

Findings
Overall, the current knowledge on finance managers in family firms is scant and fragmented. At the same time, this paper’s review findings indicate that finance managers can play decisive roles in family firms, which is why we need further research on their roles. Upper echelons theory is suggested in this paper as a theoretical framework that is well suited to guide such further research.

Originality/value
This is the first review of the academic literature on finance managers in family firms. Its main value lies in providing a theory-informed synthesis of current research on this topic and highlighting fruitful future research avenues.

Published: May 2017

PurposeThe purpose of this paper is to describe how an Academic Health Science Centre, providing pediatric rehabilitation services, research, and education, developed a Centres for Leadership (CfL) initiative to integrate its academic functions and embrace the goal of being a learning organization.Design/methodology/approachHistorical documents, tracked output information, and staff members’ insights were used to describe the ten-year evolution of the initiative, its benefits, and transformational learnings for the organization.FindingsThe evolutions concerned development of a series of CfLs, and changes over time in leadership and management structure, as well as in operations and targeted activities. Benefits included enhanced clinician engagement in research, practice-based research, and impacts on clinical practice. Transformational learnings concerned the importance of supporting stakeholder engagement, fostering a spirit of inquiry, and fostering leaderful practice. These learnings contributed to three related emergent outcomes reflecting “way stations” on the journey to enhanced evidence-informed decision making and clinical excellence: enhancements in authentic partnerships, greater innovation capacity, and greater understanding and actualization of leadership values.Practical implicationsPractical information is provided for other organizations interested in understanding how this initiative evolved, its tangible value, and its wider benefits for organizational collaboration, innovation, and leadership values. Challenges encountered and main messages for other organizations are also considered.Originality/valueA strategy map is used to present the structures, processes, and outcomes arising from the initiative, with the goal of informing the operations of other organizations desiring to be learning organizations.
Examining the interrelatedness between ontologies and Linked Data
Authors: Dutta Biswanath 
Published: May 2017

Purpose
Ontology and Linked Data (LD) are the two prominent web technologies that have emerged in the recent past. Both of them are at the center of Semantic Web and its applications. Researchers and developers from both academia and business are actively working in these areas. The increasing interest in these technologies promoted the growth of LD sets and ontologies on the web. The purpose of this paper is to investigate the possible relationships between them. The effort is to investigate the possible roles that ontologies may play in further empowering the LD. In a similar fashion, the author also studies the possible roles that LD may play to empower ontologies.

Design/methodology/approach
The work is mainly carried out by exploring the ontology- and LD-based real-world systems, and by reviewing the existing literature.

Findings
The current work reveals, in general, that both the technologies are interdependent and have lots to offer to each other for their faster growth and meaningful development. Specifically, anything that we can do with LD, we can do more by adding an ontology to it.

Practical implications
The author envisions that the current work, in the one hand, will help in boosting the successful implementation and the delivery of semantic applications; on the other hand, it will also become a food for the future researchers in further investigating the relationships between the ontologies and LD.

Originality/value
So far, as per the author’s knowledge, there are very little works that have attempted in exploring the relationships between the ontologies and LD. In this work, the author illustrates the real-world systems that are based on ontology and LD, discusses the issues and challenges and finally illustrates their interdependency discussing some of the ongoing research works.
Hedonic value and crowdfunding project performance: a propensity score matching-based analysis
Authors: Zhao Liang , Vinig Tsvi 
Published: May 2017

Purpose
In the existing literature on crowdfunding project performance, previous studies have given little attention to the impact of investors’ hedonic value and utilitarian value on project results. In a crowdfunding setting, utilitarian value is somehow hard to satisfy due to information asymmetry and adverse selection problem. Therefore, the projects with more hedonic value can be more attractive for potential investors. Lucky draw is a method to increase consumer hedonic value, and it can influence investors’ behavior as a result. The authors hypothesize that projects with hedonic treatment (lucky draw) may have higher probability to win their campaign than others. The paper aims to discuss these issues.

Design/methodology/approach
A unique self-extracted two-year Chinese crowdfunding platform real data set has been applied as the analysis sample. The authors first employ propensity score matching methods to control for the endogeneity of hedonic treatment adoption (lucky draw). The authors then run OLS regression and probit regression in order to test the hypotheses.

Findings
The analysis suggests a significant positive relationship not only between project lottery adoption and project results but also between project lottery adoption and project popularity.

Originality/value
The results suggest that an often ignored factor – hedonic treatment (lucky draw) – can play an important role in crowdfunding project performance.

Published: May 2017

AbstractIntroductioneviQ Cancer Treatments Online is a free, web‐based resource providing access to over 600 evidence‐based treatment protocols in medical oncology, radiation oncology, hematology and cancer genetics. With over 60 000 registrants from 148 countries, eviQ is widely used by cancer clinicians globally. The aim of this study was to examine the perceived quality of eviQ by Australian medical oncologists, the impact it had on their knowledge and practice, and the effect it had on their patients.MethodsA web‐based survey was administered to members of the Medical Oncology Group of Australia by email. Two reminders emails were sent to encourage participation.ResultsOf the 97 respondents (15%), all but one, were practicing in Australia, with varying years of oncology experience (<2 years: 25%, 2–10 years: 36%, >10 years: 39%). eviQ was most frequently used as a source for providing patient information sheets on chemotherapy side effects, with 57% of respondents using eviQ for this purpose. Other uses included accessing side effect information (27%), checking drug doses (26%) and guiding dose adjustments (22%). The majority of respondents rated eviQ as current, accurate and relevant with over 90% agreeing that eviQ was of a high quality. Most of the respondents reported that they provided better care with enhanced patient experiences as a result of using eviQ.ConclusionseviQ was highly regarded by Australian medical oncologists who responded to our survey. The results suggested that usage of eviQ had a positive impact on individual knowledge, practice and promoted better patient‐centered care.

SummaryThe clinical effectiveness of patient‐controlled analgesia has been demonstrated in a variety of settings. However, patient‐controlled analgesia is rarely utilised in the Emergency Department. The aim of this study was to compare the cost‐effectiveness of patient‐controlled analgesia vs. standard care in participants admitted to hospital from the Emergency Department with pain due to traumatic injury or non‐traumatic abdominal pain. Pain scores were measured hourly for 12 h using a visual analogue scale. Cost‐effectiveness was measured as the additional cost per hour in moderate to severe pain avoided by using patient‐controlled analgesia rather than standard care (the incremental cost‐effectiveness ratio). Sampling variation was estimated using bootstrap methods and the effects of parameter uncertainty explored in a sensitivity analysis. The cost per hour in moderate or severe pain averted was estimated as £24.77 (€29.05, US$30.80) (bootstrap estimated 95%CI £8.72 to £89.17) for participants suffering pain from traumatic injuries and £15.17 (€17.79, US$18.86) (bootstrap estimate 95%CI £9.03 to £46.00) for participants with non‐traumatic abdominal pain. Overall costs were higher with patient‐controlled analgesia than standard care in both groups: pain from traumatic injuries incurred an additional £18.58 (€21.79 US$23.10) (95%CI £15.81 to £21.35) per 12 h; and non‐traumatic abdominal pain an additional £20.18 (€23.67 US$25.09) (95%CI £19.45 to £20.84) per 12 h.
