Authors: Ko Changsuk , Haney Mark H. , Lee Gukseong 
Published: May 2018

PurposeThe purpose of this paper is to explore how ethical leadership and formal control systems influence employee opportunistic behavior.Design/methodology/approachUsing survey data collected from Chinese employees (N=430), the authors conducted regression analysis to test hypothesized relationships between ethical leadership and formal control systems and employee opportunistic behavior. Both direct effects and an interaction effect were tested.FindingsThe authors found that both ethical leadership and formal control systems individually play significant roles in reducing employee opportunistic behavior. In addition, the results indicate that ethical leadership and formal control systems function as complements to jointly constrain employee opportunistic behaviors.Originality/valueThis study contributes to an understanding of the relationship between supervisors and followers in China by demonstrating the effects of ethical leadership and formal control systems on employee opportunistic behaviors, including an interesting interaction effect.
Denmark: the long-lasting class compromise
Authors: Lind Jens , Knudsen Herman 
Published: May 2018

Purpose
The purpose of this paper is to offer a critical examination of industrial relations in Denmark.

Design/methodology/approach
The approach is based upon available data and a mixture of Marxist theory and systems theory. The theoretical position is discussed in relation to the academic discourses on the main characteristics of Danish industrial relations and provides a review of the foundation and historical development of the Danish system.

Findings
From this basis, it is analysed how the stagnation or decline has taken place in recent years regarding representation of workers’ interest as well as the ability of the Danish system to maintain its key importance when challenged by decentralisation, decreasing union affiliation rates, cuts in unemployment insurance and social dumping due to labour migration.

Originality/value
It is an original paper which offers a critical analysis of the institutional decline and increasing inequality that are the result of the liberalist political-economic hegemony.
Audit report forecast: an application of nonlinear grey Bernoulli model
Authors: Salehi Mahdi , Dehnavi Nastaran 
Published: May 2018

Purpose
The widespread application of traditional grey model (GM) in different academic fields such as electrical engineering, education, mechanical engineering and agriculture provided the authors with an incentive to conduct the present empirical research in an accounting field, in particular, auditing practice. In this regard, the purpose of this paper is to employ the nonlinear type of the original GM to forecast the drastically changed data on audit reports, primarily due to the fact that the linear nature of GM is unable to forecast nonlinear data precisely. In essence, this paper adds value to the strand of audit report literature by examining the impact of different financial ratios on auditors’ opinion and then forecasting audit reports by employing GMs.

Design/methodology/approach
The grey forecasting model is known as a system containing uncertain information presented by grey numbers, equations and matrices. The grey forecasting model is employed by using a differential equation in an uncertain system with limited data set which is suitable for smoothing discrete data. In addition, the analyses are conducted by applying a sample of top 50 listed companies on the Tehran Stock Exchange during 2011-2016.

Findings
The findings suggest that audit reports are most influenced by the current ratio and conversely, least influenced by the ratio of working capital turnover. Moreover, the authors argue that the Nash nonlinear grey Bernoulli model is more precise than the nonlinear grey Bernoulli model and GM in forecasting audit reports.

Originality/value
The current study may give more strength to stakeholders in order to analyse and forecast audit report.
Formulating optimal business process change decisions using a computational hierarchical change management structure framework
Authors: Alrabiah Abdulrahman , Drew Steve 
Published: May 2018

PurposeThis paper first aims to examine how business process change decisions (BPCDs) were implemented in a government organisation bound by tightly coupled temporal constraints (TTCs). Second, it focuses on how to achieve optimal and efficient BPCDs that require tight compliance with regulators’ temporal constraints. Finally, it formulates a rigorous framework that can facilitate the execution of optimal BPCDs with maximum efficiency and minimal effort, time and cost.Design/methodology/approachDecision-making biases by individuals or groups in organisations can impede optimal BPC implementation; to demonstrate this, a case study is investigated and the formulated framework is applied to tackle these failings.FindingsThe case study analysis shows 76 per cent of the BPCDs implemented were inefficient, mostly because of poor decisions, and these resulted in negative ripple effects. In response, the newly developed hierarchical change management structure (HCMS) framework was used to empower organisations to execute high-velocity BPCDs, enabling them to handle any temporal constraints imposed by regulators or other exogenous factors. The HCMS framework was found to be highly effective, scoring an average improvement of more than 100 per cent when measured using decision quality dimensions. This paper would be of value for business executives and strategic decision makers engaging with BPC.Research limitations/implicationsThe HCMS framework has been applied in a single case study as a proof of concept. Future research could extend its application to broader domains that have multi-attribute structures and environments. The evaluation processes of the proposed framework are based on subjective metrics. Causal links from the framework to business process metrics will provide a more complete performance picture.Practical implicationsThe outcome of this research assists in formulating a systematic BPCD framework that is otherwise unavailable. The practical use of the proposed framework would potentially impact on quality outcomes for organisations. The model is derived from decision trees and analytical hierarchical processes and is tailored to address this problematic area. The proposed HCMS framework would help organisations to execute efficient BPCDs with minimal time, effort and cost. The HCMS framework contributes to the academic literature on BPCD that leverages diverse stakeholders to engage in BPC initiatives.Originality/valueThe research presents a novel framework –HCMS – that provides a platform for organisations to easily determine and solve hierarchical decision structure problems, thereby allowing them to efficiently automate and institutionalise optimal BPCDs.
The use of activity theory and actor network theory as lenses to underpin information systems studies
Authors: Nehemia-Maletzky Monica , Iyamu Tiko , Shaanika Irja 
Published: May 2018

PurposeThis study aims to examine how both activity theory (AT) and actor network theory (ANT) can be complementarily applied in information system (IS) studies.Design/methodology/approachThe interpretivist approach was followed, within which the qualitative methods were used. Existing literature was gathered as data. The analysis was done by following the interpretive approach.FindingsBased on the analysis and discussion, a guide for complementary use of both AT and ANT in IS studies was developed. The guide is divided into two parts, which helps to achieve the objectives of the study: complimentary use of AT and ANT in an IS study and order-of-use of both theories in a study, as depicted in the framework.Originality/valueThis study is original in that it has not previously been published in part or full. The results of the study is intended to be of value to both IS postgraduate students and researchers.
Tourism and mobile devices: provenance of academic research through a bibliometric study
Authors: Ortega-Fraile Francisco José , Ríos-Martín Miguel Ángel , Ceballos-Hernandez Cristina 
Published: May 2018

Purpose
This paper aims to outline a map of all the research that exists on mobile technology and tourism archived in the two main databases worldwide (Web of Science and Scopus). Accordingly, with the identification of all the scientific articles that deal with both mobile technology and tourism, the authors seek to ascertain the evolution of mobile technology in the tourism sector through the years, countries, universities and authors and determine the various collaborations brought about between authors, universities, institutions and/or companies in various research projects. Finally, it also allows the authors to distinguish the main topics under study within the scope of ‘mobile tourism’.

Design/methodology/approach
A mixed methodology has been carried out. The search focused on the principal databases of bibliographic references and citations of periodical publications, such as articles from scientific journals, books and other types of printed material. Once the results were obtained in the respective databases, it was necessary to be able to work with them. In this respect, the authors had to extract the relevant data and dump it in a bibliographic reference manager, for which they chose Mendeley. After this, the tabulation of data was performed in Excel and tables and graphs were created from all the data collected.

Findings
The main results obtained and analyzed are the number of articles per year, countries and universities. In the same way, it is interesting to highlight the number of countries and universities that participate in each article under study. On the other hand, an analysis has been carried out regarding the number of articles per author, as well as the topics dealt with in the different articles.

Originality/value
This analysis reveals the role that has been played by mobile phones in tourism since the first scientific article was recorded in 2002. In this regard, in recent years there has been a significant increase in the number of articles, finally resulting in moderate figures in relation to countries (40) and universities (233) that have formed part of the subject matter under study. In contrast to other areas of research in tourism, the relevance of this subject is therefore evident, as is the need for greater background knowledge to establish research models adapted to the new reality of tourism in a world of ever-increasing mobility.
The meaning of a brand? An archetypal approach
Authors: Xara-Brasil Duarte , Miadaira Hamza Kavita , Marquina Percy 
Published: May 2018

Purpose
The purpose of this paper is to analyze customers’ perceptions about brand personality in different cultural environments, checking if the archetypal framework of Mark and Pearson (2001) applies to different brands across countries.

Design/methodology/approach
The authors measured consumers’ perceptions in different cultural contexts through a survey, and received 537 valid questionnaires from Portugal, Brazil, Colombia and Peru, countries that have some similar indicators of cultural proximity. The authors wanted to verify if the words and sentences that respondents related to each brand were coherent with the archetype/brand, and the homogeneity of the results in different cultural contexts.

Findings
Empirical evidence shows that there is proximity between the literature review and the associations – words and sentences – that consumers from different countries make with those brands. This consistency of results is significantly higher for word associations.

Originality/value
Regardless of the results, the perceptions of consumers expressed through the selected words were often diverse and heterogeneous among countries. This could possibly indicate insufficient efforts from global brands toward a coherent brand personality/global-archetypal approach. Therefore, managing brand personality deserves more attention and marketers must understand consumer behavior patterns in different markets.
The characteristic time‐scale of perceived information for decision‐making: Departure from thermal columns in soaring birds
Authors: Harel Roi , Nathan Ran 
Published: May 2018

Abstract

Animals are often required to make decisions about their use of current resources while minimising travel costs and risks due to uncertainty about the forthcoming resources. Passive soaring birds utilise warm rising‐air columns (thermals) to climb up and obtain potential energy for flying across large areas. However, the utilisation of such inconsistent natural resources may be challenging for soaring‐gliding birds and involve a set of decisions to maintain efficient flight.

To assess which temporal scales of previous experience with environmental inputs best predicted thermal‐climbing departure decisions of soaring birds, we used movement data from Eurasian griffon vultures (Gyps fulvus) tracked by GPS transmitters. We applied Cox proportional hazard regression and a model selection approach to identify thermal‐climbing departure decisions and to compare a range of temporal scales.

Our findings support the use of current and recent (short‐term; last 20 min) experiences, compared to longer term, past experiences, in predicting the time until departure from thermals. The models supported decision rules that integrated information originating from different temporal scales, implying a tendency to depart from a thermal later when the current climb rate was higher than experienced recently and vice versa. In addition, climb rates in thermals revealed significant autocorrelation over short time‐scales (shorter than 30 min).

The correspondence between thermals' characteristics and the factors that best predicted thermal‐climbing departure decisions presumably reflects optimal decisions individuals make to handle their dynamic environment and to reduce movement‐related costs of such a basic activity for soaring‐gliding birds.

Global drivers of tree seedling establishment at alpine treelines in a changing climate
Authors: Lett Signe , Dorrepaal Ellen 
Published: May 2018

Abstract

Alpine and Arctic treeline expansion depends on establishment of tree seedlings beyond the current treeline, which is expected to occur with climate warming. However, treelines often fail to respond to higher temperatures, and it is therefore likely that other environmental factors are important for seedling establishment.

We aimed to analyse our current understanding of how temperature and a range of other environmental drivers affect tree seedling establishment at the alpine and Arctic treelines world‐wide and to assess the relative importance of temperature compared with other factors and how they interact.

We collected 366 observations from 76 experimental and observational papers for a qualitative analysis of the role of a wide range of environmental factors on tree seed germination, tree seedling growth, survival and natural occurrence. For a subset of these studies, where the experimental design allowed, we conducted formal meta‐analyses to reveal if there were global drivers for different seedling life traits.

The analyses showed that a wide range of abiotic and biotic factors affected tree seedling establishment besides from temperature, including water, snow, nutrients, light and surrounding vegetation. The meta‐analyses showed that different seedling life stages do not respond similarly to environmental factors. For example, temperature had positive effects on growth, while tree seedling survival and germination showed mixed responses to warming. Further, warming was as often as not the strongest factor controlling tree seedling establishment, when compared to with one of five other environmental factors. Moreover, warming effects often depended on other factors such as moisture or the presence of surrounding vegetation.

Our results suggest that population dynamics of trees at the alpine and Arctic treeline is responsive to environmental changes and show that there is a clear need for multifactorial studies if we want to fully understand and predict the interplay between warming and other environmental factors and their effect on tree seedling establishment across current treelines.

Death of a Female Prostitute Due to Intestinal Obstruction by an Unknown Substance
Authors: Dokoupil Marek , Marecová Klára , Handlos Petr , Březina Petr 
Published: May 2018

AbstractA young adult black female, known to be a prostitute and suspected of smuggling narcotics, was found dead in her apartment in a state of early decomposition. Oval‐shaped gray‐white masses of exogenous origin protruded from the anus. The autopsy showed dilatation of the folds of the large intestine, which were almost completely filled with these oval‐shaped gray‐white masses of foreign material. The uterus was enlarged with multiple large leiomyomas. Toxicological tests of blood and the foreign material revealed no toxicologically relevant substances. Kaolin was detected in a sample of the foreign material from the large intestine. The immediate cause of death was intestinal obstruction due to the formation of a kaolin bezoar with simultaneous compression of the large intestine by the enlarged myomatous uterus. Subsequent revelation of a habit the deceased had brought from her native country led to the conclusion that this exotic custom was responsible for her death.
The effect of filtration method on the efficiency of environmental DNA capture and quantification via metabarcoding

Published: May 2018

AbstractEnvironmental DNA (eDNA) is a promising tool for rapid and noninvasive biodiversity monitoring. eDNA density is low in environmental samples, and a capture method, such as filtration, is often required to concentrate eDNA for downstream analyses. In this study, six treatments, with differing filter types and pore sizes for eDNA capture, were compared for their efficiency and accuracy to assess fish community structure with known fish abundance and biomass via eDNA metabarcoding. Our results showed that different filters (with the exception of 20‐μm large‐pore filters) were broadly consistent in their DNA capture ability. The 0.45‐μm filters performed the best in terms of total DNA yield, probability of species detection, repeatability within pond and consistency between ponds. However performance of 0.45‐μm filters was only marginally better than for 0.8‐μm filters, while filtration time was significantly longer. Given this trade‐off, the 0.8‐μm filter is the optimal pore size of membrane filter for turbid, eutrophic and high fish density ponds analysed here. The 0.45‐μm Sterivex enclosed filters performed reasonably well and are suitable in situations where on‐site filtration is required. Finally, prefilters are applied only if absolutely essential for reducing the filtration time or increasing the throughput volume of the capture filters. In summary, we found encouraging similarity in the results obtained from different filtration methods, but the optimal pore size of filter or filter type might strongly depend on the water type under study.

AbstractDetermining the species compositions of local assemblages is a prerequisite to understanding how anthropogenic disturbances affect biodiversity. However, biodiversity measurements often remain incomplete due to the limited efficiency of sampling methods. This is particularly true in freshwater tropical environments that host rich fish assemblages, for which assessments are uncertain and often rely on destructive methods. Developing an efficient and nondestructive method to assess biodiversity in tropical freshwaters is highly important. In this study, we tested the efficiency of environmental DNA (eDNA) metabarcoding to assess the fish diversity of 39 Guianese sites. We compared the diversity and composition of assemblages obtained using traditional and metabarcoding methods. More than 7,000 individual fish belonging to 203 Guianese fish species were collected by traditional sampling methods, and ~17 million reads were produced by metabarcoding, among which ~8 million reads were assigned to 148 fish taxonomic units, including 132 fish species. The two methods detected a similar number of species at each site, but the species identities partially matched. The assemblage compositions from the different drainage basins were better discriminated using metabarcoding, revealing that while traditional methods provide a more complete but spatially limited inventory of fish assemblages, metabarcoding provides a more partial but spatially extensive inventory. eDNA metabarcoding can therefore be used for rapid and large‐scale biodiversity assessments, while at a local scale, the two approaches are complementary and enable an understanding of realistic fish biodiversity.

ObjectiveTo determine the amount and nature of health professional education related to fall prevention for older adults in Australian and New Zealand universities.MethodsUniversities offering medicine, nursing and allied health courses were invited to complete an online survey enquiring about fall prevention course‐related information: topics; delivery mode; and time dedicated.ResultsOne hundred and five respondents, 11 disciplines and 43 universities completed the survey. Courses were primarily undergraduate level (90%) and delivered face‐to‐face (93%). Time dedicated to fall prevention was usually one to three hours of lectures (>65% of courses) and 1–3+ hours of tutorials/practical sessions (>80% of courses).ConclusionsSurvey results indicate that education of health professionals across a range of disciplines in Australia and New Zealand does include older adult fall prevention. Education of all health and exercise professionals about falls is vital given their critical role in the prevention and management of falls in our rapidly ageing population.
