Price overreactions in the cryptocurrency market
Authors: Caporale Guglielmo Maria , Plastun Alex 
Published: September 2019

PurposeThe purpose of this paper is to examine price overreactions in the case of the following cryptocurrencies: bitcoin, litecoin, ripple and dash.Design/methodology/approachA number of parametric (t-test, ANOVA, regression analysis with dummy variables) and non-parametric (Mann–WhitneyU-test) tests confirm the presence of price patterns after overreactions: the next day price changes in both directions are bigger than after “normal” days. A trading robot approach is then used to establish whether these statistical anomalies can be exploited to generate profits.FindingsThe results suggest that a strategy based on counter-movements after overreactions is not profitable, whilst one based on inertia appears to be profitable but produces outcomes not statistically different from the random ones. Therefore, the overreactions detected in the cryptocurrency market do not give rise to exploitable profit opportunities (possibly because of transaction costs) and cannot be seen as evidence against the efficient market hypothesis (EMH).Originality/valueThe overreactions detected in the cryptocurrency market do not give rise to exploitable profit opportunities (possibly because of transaction costs) and cannot be seen as evidence against the EMH.
Does financial health influence the re-election of local governments?
Authors: Cuadrado-Ballesteros Beatriz , Santis Serena , Citro Francesca , Bisogno Marco 
Published: September 2019

Purpose
The purpose of this paper is to investigate the possible influence of financial health of local governments (LGs) on the re-election of politicians.

Design/methodology/approach
The study investigates a sample of 129 Italian LGs with more than 50,000 inhabitants for the period 2008–2014, resulting in 903 observations. A regression model has been implemented, where the dependent variable refers to the probability of re-election, and different dimensions of financial health are the independent variables.

Findings
Budgetary and service-level solvency influence positively the probability of re-election of the major, while the ability of the government to generate liquidity to pay its short-term debts is not statistically relevant. Moreover, the sustainability dimension of budgetary solvency is more relevant than the flexibility and vulnerability dimensions.

Practical implications
To be re-elected, local politicians are advised to pay attention to and preserve the social welfare of citizens with the available resources.

Originality/value
This study adds fresh insight to the literature on financial health, emphasising the relevance of public financial management in the re-election of local politicians.
Actions speak louder than words

Published: September 2019

PurposeThe purpose of this paper is to expand our understanding on team listening by incorporating an action component. The authors empirically test the effect of this expanded concept, namely team action listening on team success, and investigate how team commitment moderates the relationship between team trust and team action listening.Design/methodology/approachThe authors explored listening in teams in the field and in the lab, both qualitatively and quantitatively, through studying 474 team members representing 100 teams. The authors tested the hypotheses by structural equation modeling augmented with in-depth team interviews.FindingsThe findings showed that: teams demonstrate that they listen by taking action, teams that exhibit action listening are more successful, there is a direct relationship between team trust and team action listening and team commitment negatively moderates this relation in larger teams.Practical implicationsManagers should encourage taking action in team discussions. Yet, they should be wary of the detrimental effects of team commitment to team action listening particularly in teams with high trust. Commitment increases the risk of groupthink and decreases the participation to team discussions and listening. In particular, managers may benefit from keeping the team smaller, as in large teams, commitment suppresses the relationship between trust and team action listening.Originality/valueThis study extends research on team listening by adding the action aspect that distinguishes successful teams. It is one of the first to investigate the interrelationships between team trust, commitment, team action listening and success in teams.
An overview of C-SOX and directions for future research
Authors: Bhabra Harjeet S. , Hossain Ashrafee Tanvir , Karmakar Vidyoot Roy 
Published: September 2019

Purpose
The purpose of this paper is to examine existing literature, including both academic and practitioner publications, related to Canadian SOX (or C-SOX as it is popularly known). The study discusses the origins of the Act, the underlying motivations for enacting this legislation in Canada and its impact on corporate decisions since its inception in 2003.

Design/methodology/approach
The principal focus of this literature review is on C-SOX, its inception, reception, compliance and impact in Canada, both from business’ and investors’ critical perspectives. The authors have followed a two-step process to gather all the articles. First, the authors used a keyword search at Google Scholar and ProQuest (e.g. C-SOX, Canadian SOX, Bill 198, etc.) to gather all the articles. Second, the authors retained articles and abstracts that primarily dealt with the background framework and impact of the legislation. It is to be noted that C-SOX was mainly a reactionary legislation following the adoption of US-SOX in 2002. Any discussion of C-SOX is, therefore, incomplete without referencing the literature related to US-SOX.

Findings
In this review paper the evolution of C-SOX over time in Canada, as well as studies on its impacts and criticisms have been summarized. Based on the extensive research that followed the enactment of US-SOX, the authors also provide suggested research directions related to C-SOX in the future.

Research limitations/implications
C-SOX has been relatively underexplored and therefore, not much academic work is available presently. This study highlights this gap in the literature with the hope that researchers will devote their energy to understanding the broader ramifications of major legislations such as C-SOX which will potentially also inform future public policy choices.

Practical implications
This research will help both businesses and investors to understand each other’s perspectives and concerns regarding C-SOX. This paper will also be helpful to policy makers to identify potential areas of improvement in this and future legislative decisions in the future.

Originality/value
Using a qualitative approach this study combines the development of C-SOX as a legislation in Canada, its overall effectivity/drawbacks and explores the areas it impacts, both positively and negatively, along with criticisms and appreciations.
Corporate payouts in dual classes
Authors: Lei Adam Y.C. , Li Huihua , Yu Jin 
Published: September 2019

Purpose
The purpose of this paper is to examine the dividend payments and share repurchases of dual-class firms that have both their superior voting shares and inferior voting shares publicly traded.

Design/methodology/approach
This paper uses matched dual-class and single-class samples from 1994 to 2015 and logit models to evaluate the likelihoods of dividend payment and share repurchase between dual-class firms and single-class firms.

Findings
The results show that dual-class firms are more likely than the matched sample of single-class firms to pay dividends in both share classes. Dual-class firms, however, are more likely to repurchase their superior shares than single-class firms and their inferior shares.

Research limitations/implications
The results suggest that dual-class firms do not use corporate payouts to either mitigate agency problems or maintain the private benefits of control. Instead, dual-class firms use dividend payments to mitigate agency problems while using repurchases of superior shares to maintain the private benefits of control, which supports the agency payout hypothesis.

Practical implications
This paper highlights the differences between dividend payments and share repurchases as forms of corporate payouts and suggests that firms may choose a particular form for a particular purpose.

Originality/value
This paper provides the first piece of empirical evidence on the corporate payouts of dual-class firms separating their superior voting shares and inferior voting shares.
Factors influencing the implementation of electronic records and information management
Authors: Abdullah Azlan Long , Mohammad Yusof Zawiyah , Mokhtar Umi Asma 
Published: September 2019

Purpose
The purpose of this paper is to explore, identify and gain insight into factors related to electronic records and information management (e-RIM) issues and their influence on the implementation of e-RIM initiative in military service in Malaysia. This exploration was conducted via a literature review and case study.

Design/methodology/approach
This study adopted a qualitative approach and used a case study involving two army departments in Malaysia. Interviews triangulated by document content analysis and observations were used for data collection. The data were analysed using a directional content analysis approach.

Findings
This study reveals that people, organizations, technology and processes are the interrelated contexts underlying e-RIM issues which inevitably influence the implementation of e-RIM initiatives. Competency and leadership, governance structure, culture and strategic planning, technology development and record-keeping process are the main factors impacting such efforts, in turn forming potential obstacles for organizations implementing such initiatives.

Research limitations/implications
The research approach and design adopted and the sample size were insufficient for generalization of the findings.

Practical implications
This study shows that e-RIM initiatives pose greater challenges related to various issues that cause difficulties in improving and implementing the initiative. Thus, it is crucial for organizations to ascertain and comprehend the factors that influence e-RIM initiatives prior to formulating strategies and approaches in addressing those factors, which would in turn affect the implementation of e-RIM initiatives.

Originality/value
This study provides insights into the fundamental factors embracing the e-RIM issues which influence the initiatives, and thereby fosters further discussion and research in the subject matter in Malaysia.
Dynamic analysis of the relationship between stock prices and macroeconomic variables
Authors: Chang Bisharat Hussain , Meo Muhammad Saeed , Syed Qasim Raza , Abro Zahida 
Published: September 2019

PurposeThe purpose of this paper is of twofold: first, to empirically examine the short-run and long-run impact of macroeconomic variables such as industrial production, foreign direct investment (FDI), trade balance (TB), exchange rate, interest rate (IR) and consumer price index (CPI) on stock prices (SP) of KSE-100 index; and second, to examine whether this relationship changes as a result of the financial crisis.Design/methodology/approachThis study uses an autoregressive distributed lag model by using the full sample period data from 1997Q3 to 2018Q2 and the post-crisis period data from 2008Q3 to 2018Q2. Moreover, it uses variance decomposition analysis to examine the importance of each variable in explaining SP.FindingsThe findings of the full sample period indicate that in the long run, TB, exchange rate and IR negatively affect SP whereas CPI and industrial production positively affect SP. However, the post-crisis period data indicate that only CPI positively affects the SP in the long run. Finally, variance decomposition analysis indicates 30 percent variance in SP is explained by its own shock.Practical implicationsThe study findings suggest that macroeconomic variables have a significant role and can be considered important for taking investment and/or policy decisions. Especially, Governments and other regulators may need to take measures to increase the TB since it can help to increase the performance of the Pakistani stock market. Furthermore, investors may consider that findings change when the financial crisis has been taken into consideration.Originality/valueThis study uses two additional variables, namely FDI and TB by using the robust technique in the context of emerging countries like Pakistan. Furthermore, it takes into account the impact of the financial crisis on the underlying variables.
Zone-based sink mobility in wireless sensor networks
Authors: A. Prasanth , S. Pavalarajan 
Published: September 2019

Purpose
The purpose of this paper is to enhance the network lifetime of WSN. In wireless sensor network (WSN), the sensor nodes are widely deployed in a terrestrial environment to sense and evaluate the physical circumstances. The sensor node near to the sink will deplete more energy faster than other nodes; hence, there arises an energy hole and network partitioning problem in stationary sink-based WSN. Even though many mobile sink-based WSN is formulated to mitigate energy hole, inappropriate placement of sink leads to packet drop and affect the network lifetime of WSN. Therefore, it is necessary to have an efficient sink mobility approach to prevent an aforesaid problem.

Design/methodology/approach
In this paper, zone-based sink mobility (ZBSM) approach is proposed in which the zone formation along with controlled sink mobility is preferred for energy hole mitigation and optimal sink node placement. In ZBSM, the sink decides to move toward strongly loaded zone (SLZ) for avoiding network partitioning problems where the selection of SLZ can be carried out by using Fuzzy Logic.

Findings
The performance results confirm that the proposed scheme reduces energy consumption as well as enhances the network lifetime compared with an existing scheme.

Originality/value
A new optimal sink node placement is proposed to enhance the network lifetime and packet delivery ratio of WSN.
The importance of functional responses among competing predators for avian nesting success
Authors: Ellis Kristen S. , Larsen Randy T. , Koons David N. 
Published: September 2019

AbstractThe relationship between the rate of predation and prey abundance is an important component of predator–prey dynamics. However, functional responses are less straightforward when multiple predators compete for shared prey. Interactions among competing predators can reduce or enhance effects of predation on prey populations. Because many avian populations experience high rates of nest predation, understanding the role of specific predators on nest mortality will lead to more informed conservation and management strategies which attempt to increase productivity by removing certain predators or managing habitat to limit their impact.Our goal was to evaluate effects of specific predators and the influence of nest abundance on nest mortality.We monitored snowy ploverCharadrius nivosusnests across 7 years at two study areas in Utah, USA, with remote cameras. We modelled predator‐specific hazard rates for nest mortality in a Bayesian framework to assess relationships between competing predators and the role of nest abundance on predator‐specific hazard rates.We found that hazard rates for nest mortality by gullsLarusspp. decreased with increasing nest abundance, whereas nest mortality by foxesVulpesspp. and ravensCorvus coraxinitially increased, indicating that dietary switching may occur when nests become more abundant. Nest mortalities of specific predators were often not independent and ranged between compensatory (e.g. mammalian mesopredators) and superadditive (e.g. avian predators) across the breeding season.The non‐independence between nest mortalities suggests that reductions in some predators may not translate to additive increases in overall nest success. Analyses of cause‐specific mortality are rarely applied to avian nests, but examination of interacting impacts among competing predators on nest survival may provide insight into specific drivers of avian population dynamics.A freePlain Language Summarycan be found within the Supporting Information of this article.
Low‐productivity boreal forests have high conservation value for lichens
Authors: Hämäläinen Aino , Strengbom Joachim , Ranius Thomas 
Published: September 2019

Abstract

Land set aside for preservation of biodiversity often has low productivity. As biodiversity generally increases with productivity, due to higher or more diverse availability of resources, this implies that some of the biodiversity may be left unprotected. Due to a lack of knowledge on the species diversity and conservation value of low‐productivity habitats, the consequences of the biased allocation of low‐productivity land for set‐asides are unknown.

We examined the conservation value of boreal low‐productivity forests (potential tree growth <1 m3 ha−1 year−1) by comparing assemblages of tree‐ and deadwood‐dwelling lichens and forest stand structure between productive and low‐productivity forest stands. We surveyed 84 Scots pine‐dominated stands in three regions in Sweden, each including four stand types: two productive (managed and unmanaged) and two low‐productivity stands (on mires and on thin, rocky soils).

Lichen species richness was the highest in low‐productivity stands on thin soil, which had similar amounts and diversity of resources (living trees and dead wood) to productive unmanaged stands. Stands in low‐productivity mires, which had low abundance of living trees and dead wood, hosted the lowest lichen richness. Lichen species composition differed among stand types, but none of them hosted unique species. The differences in both species richness and composition were more pronounced in northern than in southern Sweden, likely due to shorter history of intensive forestry.

Synthesis and applications. Boreal low‐productivity forests can have as high conservation value as productive forests, which should be reflected in conservation strategies. However, their value is far from uniform, and conservation planning should acknowledge this variation and not treat all low‐productivity forests as a uniform group. Some types of low‐productivity forest (e.g. on rocky soil) are more valuable than others (e.g. on mires), and should thus be prioritized in conservation. It is also important to consider the landscape context: low‐productivity forests may have higher value in landscapes where high‐productivity forests are highly influenced by forestry. Finally, although low‐productivity forests can be valuable for some taxa, productive forests may still be important for other taxa.
The Evolution and Cultural Framing of Food Safety Management Systems—Where From and Where Next?
Authors: Manning Louise , Luning Pieternel A , Wallace Carol A 
Published: September 2019

AbstractThe aim of this paper is to review the development of food safety management systems (FSMS) from their origins in the 1950s to the present. The food safety challenges in modern food supply systems are explored and it is argued that there is a need for a more holistic thinking approach to food safety management. The narrative review highlights that while the transactional elements of how FSMS are developed, validated, implemented, monitored, and verified remains largely unchanged, how organizational culture frames the operation and efficacy of FSMS is becoming more important. The evolution of a wider academic and industry understanding of both the influence of food safety culture (FS‐culture) and also how such culture frames and enables, or conversely restricts the efficacy of the FSMS is crucial for consumer well‐being. Potential research gaps worthy of further study are identified as well as recommendations given for the application of the research findings within the food industry.
The medial breast margin sign: A new sign of pectus excavatum in adult females and comparison with classic signs
Authors: Hapuarachchi Kamal S , Cowan Ian A 
Published: September 2019

AbstractIntroductionPectus excavatum (PX) denotes a concavity of the sternum and is the most common chest wall deformity. Many characteristic signs have been described on frontal chest radiographs including increased density of the inferomedial right lung, blurring of the right heart border, steeply angled anterior ribs, horizontal posterior ribs, straight or convex left heart border and loss of silhouette of the descending thoracic aorta. These signs are often subtle and rarely all present in any individual. We describe a further sign in women with PX, the medial breast margin sign. This sign consists of more sharply defined and more vertically oriented medial breast borders on frontal chest radiographs than in those of women with normal chest wall morphology. This study aims to document the sensitivity, specificity and inter‐observer reliability of the new sign, and compare with that of the previously described signs in patients with varying degrees of PX.MethodsThe frontal chest radiographs of 185 women with PX and 50 women with normal chest wall morphology were assessed by two reviewers for the presence of the new sign and previously described signs. All the signs had their sensitivity, specificity and inter‐observer reliability calculated.ResultsThe new sign had a sensitivity of 0.48, a specificity of 0.96 and inter‐observer reliability of κ = 0.79, ranking third, second and first among all other signs, respectively.ConclusionThe medial breast margin sign is useful in diagnosing PX and is comparable to the previously described classic signs.
