An investigation on impacts of structural changes in stocks’ past returns on financial analysts’ earnings forecasting rationality
Authors: Kang Zhixin 
Published: October 2019

Purpose
The purpose of this paper is to test whether financial analysts’ rationality in making stocks’ earnings forecasts is homogenous or not across different information regimes in stocks’ past returns.

Design/methodology/approach
By treating stocks’ past returns as the information variable in this study, the authors employ a threshold regression model to capture and test threshold effects of stocks’ past returns on financial analysts’ rationality in making earnings forecasts in different information regimes.

Findings
The results show that three significant structural breaks and four respective information regimes are identified in stocks’ past returns in the threshold regression model. Across the four different information regimes, financial analysts react to stocks’ past returns quite differently when making one-quarter ahead earnings forecasts. Furthermore, the authors find that financial analysts are only rational in a certain information regime of stocks’ past returns depending on a certain return-window such as one-quarter, two-quarter or four-quarter time period.

Originality/value
This study is different from those in the existing literature by arguing that there could exist heterogeneity in financial analysts’ rationality in making earnings forecasts when using stocks’ past returns information. The finding that financial analysts react to stocks’ past returns differently in the different information regimes of past returns adds value to the research on financial analysts’ rationality.
The role of emotional exhaustion among public healthcare professionals
Authors: López-Cabarcos M. Ángeles , López-Carballeira Analía , Ferro-Soto Carlos 
Published: October 2019

Purpose
The nature of public healthcare highlights not only the need of understanding the role of emotional exhaustion in the relationship between employees’ job demands and desirable employees’ job attitudes, but also to adequate the combination of certain job resources and other organisational variables to moderate the employees’ feelings of emotional exhaustion. The paper aims to discuss this issue.

Design/methodology/approach
This viewpoint designs the theoretical approach that aims to understand the mediating role of emotional exhaustion among healthcare professionals and the capacity of certain variables to moderate it. The nature of the variables considered and the design of the theoretical model proposed highlights structural equation modelling as an optimal methodology to be used among a sample of European healthcare professionals.

Findings
Managers should be able to design strategies to mitigate, eliminate and prevent the causes of emotional exhaustion in public healthcare with the objective to improve the health and quality of life of healthcare professionals, and consequently the quality of the service provided to patients and their families.

Originality/value
This viewpoint highlights the importance of analysing the influence of employees’ emotional exhaustion on their attitudes in public healthcare. Direct relationships between emotional exhaustion and certain antecedents or consequences have been studied previously; however, studies analysing the mediating role of emotional exhaustion are very scarce and show mixed results. There are also few studies analysing the moderating role of certain job resources and other organisational variables in the relationships between employees’ job demands, employees’ emotional exhaustion and employees’ job attitudes.
Adjusting for risk factors in mutual fund performance and performance persistence
Authors: Koutsokostas Drosos , Papathanasiou Spyros , Balios Dimitris 
Published: October 2019

Purpose
The purpose of this paper is to examine the performance of Greek equity mutual funds and the persistence in annual performance for the period 2008-2017 by using a variety of performance models.

Design/methodology/approach
Using all the available funds in operation and daily data, the authors apply single-index (Jensen, 1968) and multi-factor models (Fama and French, 1993; Carhart, 1997) to measure risk-adjusted returns. To assess performance persistence, a series of parametric (Bollen and Busse, 2005) and nonparametric tests (Malkiel, 1995; Brown and Goetzmann, 1995; Kahn and Rudd, 1995) is implemented.

Findings
Results show that the Greek equity mutual funds perform, on average, worse than the market index, irrespective of the performance measure applied, and the estimations obtained by the models are similar. Few managers that followed large-cap strategies, pursued stocks with high book-to-market value ratio and eliminated their exposure to the momentum effect were able to add value to their portfolios. Furthermore, a winner-picking strategy based on sustained superior performers is questioned. However, assigning fund returns to the corresponding risk factors results in the partial disappearance of persistence in performance.

Originality/value
The sample period includes the turbulent period, following the introduction of capital controls, which affected capital flows significantly. Moreover, the application of multiple performance measures enables us to investigate performance persistence in a wider spectrum.
Preliminary look at the motivators and decision-making process of medical tourists from Nigeria to India
Authors: Balogun Babatunde Abiodun 
Published: October 2019

Purpose
The past decade has witnessed a tremendous and progressive growth in the number of Nigerians who engage in medical tourism from Nigeria to India. Various commentators have advanced diverse reasons for this trend. However, there is a dearth of research that has sought to provide empirical insights. This paper aims to investigate the decision-making process of Nigerian medical tourists and why they prefer medical tourism to India to medical care locally.

Design/methodology/approach
Eight Nigerian medical tourists are interviewed on a one-on-one basis with open-ended questions using purposive criterion sampling technique from an interpretivist mind-set.

Findings
The paper identifies two major motivators, namely, inadequate medical infrastructure and poor medical, and customer service from health workers in Nigeria, which spurred medical tourism from Nigeria to India. Further, it finds that first timers premise their decisions on advice from reference groups, while previous personal experiences guide decisions on subsequent medical travels. Findings are explained using the template provided by the theory of planned behaviour.

Originality/value
This exploratory nature of this research provides a useful basis to elucidate the course of decision-making of Nigerian patients so that appropriate marketing communication channels can be applied. It improves the process of recruiting and engaging Nigerian patients and nurturing wholesome relationships between Nigerian patients and hospitals.
Democratization of organizational change process through deliberation
Authors: Värttö Mikko 
Published: October 2019

PurposeThe purpose of this paper is to examine deliberation in the context of organizational change and introduce an organizational jury as a change facilitator.Design/methodology/approachThe research is based on an empirical study of four organizational juries that were organized by a non-profit organization in Finland. The main data of the study consist of a survey that the juries’ participants filled in. The data are triangulated with observations of jury meetings and relevant documents including pre-jury information package, jury presentations and juries’ proposals. In the analysis, the paper adopts deliberative democracy criteria to assess the inclusiveness, authenticity and consequentiality of the deliberative process.FindingsThe research findings suggest that the juries increased the inclusiveness of decision making and the quality of deliberation about the changes among the employees. The results indicate that juries facilitated the change process by providing a means for information sharing and building a shared understanding among the stakeholders. The main weakness of the juries was their low consequentiality.Originality/valueDeliberative jury method provides a participative way to build and preserve socially shared meanings in an organizational change context. However, the studies on the use of deliberative forums in the organizational context are still scarce. Thus, the study provides an important addition to the existing research literature.
Linking destructive forms of leadership to employee health
Authors: Trépanier Sarah-Geneviève , Boudrias Valérie , Peterson Clayton 
Published: October 2019

PurposeThe purpose of this paper is to investigate the psychological and motivational processes involved in the relationship between two forms of destructive leadership (tyrannical and laissez-faire) and employee health (burnout, affective commitment and job performance). Drawing on self-determination theory, this paper links tyrannical and laissez-faire leadership to employee health through psychological need frustration and poor-quality (controlled) work motivation.Design/methodology/approachA total of 399 Canadian nurses took part in this cross-sectional study. Structural equational modelling analyses were conducted.FindingsResults show that tyrannical leadership frustrates nurses’ needs for autonomy, competence and relatedness, whereas laissez-faire leadership frustrates nurses’ need for autonomy only. The frustration of needs for autonomy and competence predicts low-quality (controlled) work motivation, which is consequently associated with impaired health (burnout and lower affective commitment as well as performance).Originality/valueThis study contributes to the scarce knowledge regarding the distinct outcomes of destructive forms of leadership and uncovers the specific psychological and motivational pathways through which these types of leadership influence employees’ health.
Identifying the effective taxonomies of airline green operations strategy
Authors: Migdadi Yazan Khalid Abed-Allah 
Published: October 2019

PurposeThe purpose of this paper is to explore the effective taxonomies of airline green operations strategy.Design/methodology/approachTo this end, a sample of 23 airlines from five regions (North America, South America, Europe, Asia and the Middle East) was surveyed. The annual sustainability reports of the surveyed airlines for the period 2013‒2016 were retrieved from the Global Reporting Initiatives website. K-means clustering analysis was used to generate taxonomic clusters of airline green operations strategy. A special data analysis technique, called rank analysis, was also adopted to identify the significant green actions and develop indicative models.FindingsThis study revealed that three effective taxonomies were adopted by airlines: a low-effect strategic pattern, a low-to-moderate effect strategic pattern and a high-effect strategic pattern. A different combination of green operation actions characterized each strategic pattern.Originality/valueThe research contribution of taxonomies of green operations strategy has so far been limited, country focused and concentrated on the manufacturing sector. This study reported the taxonomies and performed an in-depth analysis of the categories of effective actions taken to promote green performance. Moreover, this study developed indicative models for the relationship between categories of action and green performance for each strategic pattern, an action that has seldom been reported by previous studies of green operations strategies for airlines.

Authors: Xia Qinxiang , Ming Xinjian , Long Jinchuan , Liu Xiujuan 
Published: October 2019

Purpose
The purpose of this paper is to design the whole structure of high-speed automatic casing system (HSACS) for lithium-ion battery (LIB), and verify its rationality and reliability by kinematic simulation and casing test.

Design/methodology/approach
Based on the software of SolidWorks and ADAMS, the structure of working mechanisms for HSACS was designed, and virtual prototype models of HSACS and main turntable were established to realize the kinematic analysis. The HSACS casing test was also carried out and compared with simulation.

Findings
Simulation results for the designed HSACS were presented graphically and analyzed. The graphical results indicate that the coordination motions among the working mechanisms of HSACS are reasonable and no interference occurs. Casing test results show that the casing quality and production efficiency of HSACS equipment are satisfying.

Originality/value
In the present work, the developed virtual prototype models of HSACS provide reliable kinematic analysis results for the structural design of HSACS, and reasonable motion relations are realized in the designed structure of HSACS. Furthermore, not only the casing quality requirements can be met, but also the production efficiency of high-speed automatic casing machine for LIB is greatly improved via this kind of new HSACS structure.

Authors: Vodenko Konstantin V. , Belasheva Irina V. , Zalevskaya Anna A. , Polshakova Irina N. , Tleptserisheva Syuzanna A. 
Published: October 2019

Purpose
The purpose of this paper is to study the specifics of state management in the sphere of reproduction of the socio-professional structure of society.

Design/methodology/approach
This paper is based on the provisions of neo-Marxism; structural and functional approach, ideas of the concept of constructing the cultural senses, neo-institutional approach, theory of institutional matrices. The paper uses the provisions of the theory of “path-dependence,” in which the effect of institutional inertia of society and its influence on the management institutes are studied. During the research of the specifics of the Russian model of state management of the process of formation and development of professional and qualification potential of the country, the provisions of the concept of power-property are taken into account.

Findings
The authors note that ineffectiveness of state management in the sphere of formation and development of professional and qualification potential of the Russian society is predetermined by historically established institutes of management and organization of life, which are peculiar for authoritarianism, bureaucracy, principles of redistributive economy, domination of the institutes of power-property and underdevelopment of the institutes of the civil society. This problem could be solved by modernizing the national model of state management based on well-balanced interaction of the basic and complementary socio-cultural institutes, which could increase the effectiveness of management of complex social processes.

Originality/value
It is substantiated the main principles of the modern state regulation of the sphere of training of professional and qualification personnel should be as follows: strategic approach to management, partnership approach to managing education, investments into human capital, supporting the development of institutes of the civil society, debureaucratization of the system of management and formation of favorable legal and economic environment for development of entrepreneurship.
Dynamic balancing of cleaning unit used in agricultural thresher using Jaya algorithm
Authors: Singh Prem , Chaudhary Himanshu 
Published: October 2019

Purpose
The purpose of this paper is to propose the dynamically balanced mechanism for cleaning unit used in the agricultural thresher machine using the system of point masses.

Design/methodology/approach
The cleaning unit works on crank-rocker Grashof mechanism. To balance the mechanism, the shaking forces and shaking moments are minimized by optimizing the mass distribution of links using the dynamically equivalent system of point masses. The point mass parameters are taken as the design variables. Then, the optimization problem is solved using Jaya algorithm and genetic algorithm (GA) under suitable design constraints.

Findings
The mass, center of mass and inertias of each link are calculated using optimum design variables. These optimum parameters improve the dynamic performance of the cleaning unit.

Originality/value
The proposed methodology is tested through the standard four-bar mechanism taken from literature and also applied to the existing cleaning mechanism of the thresher machine. It is observed that the Jaya algorithm is computationally more efficient than the GA. The dynamic analysis of the proposed mechanism is simulated using ADAMS software.

Published: October 2019

AbstractTo describe the clinical features and outcomes of patients with suspected Fructus Psoraleae (FP)–induced severe liver injury who underwent treatment with two artificial liver support systems (ALSSs). The cases of 12 patients with severe liver injury by FP were enrolled. We evaluated the tolerability of, and changes in biochemical parameters after treatment with plasma exchange combined with hemofiltration and double plasma molecular absorption system, and 6‐month follow‐up information were collected. The median age of the 12 patients was 60 years and nine (75%) patients were females. All patients had jaundice as the initial symptom. Two ALSS types were used to treat the patients. The group that underwent plasma exchange combined with hemofiltration showed remarkable improvements in ALT, AST, total bilirubin (TB), GGT and international normalized ratio levels (AST, TB, international normalized ratio, P < 0.01; ALT, GGT, P < 0.05), and the levels of AST, ALP, TB, and total bile acid decreased significantly in the double plasma molecular absorption system group after treatment (TB, P < 0.01; AST, ALP, total bile acid P < 0.05). During 6 months of follow‐up, two patients died, two became chronic, and eight recovered to normal. FP can cause clinically severe liver injury, characterized by gastrointestinal symptoms and jaundice, which can lead to death or become chronic. Both ALSSs were safe and well tolerated in drug‐induced liver injury patients. After ALSS treatment, the levels of biochemical indicators of liver function improved significantly, indicating that ALSS might be beneficial for patients with severe drug‐induced liver injury.
Intuition versus Analytical Thinking and Impairment Testing
Authors: Wolfe Christopher J. , Christensen Brant E. , Vandervelde Scott D. 
Published: October 2019

ABSTRACTWe examine the use of intuition versus analytical thinking in auditor risk assessment using a task that requires auditors to assess a group of impairment indicators. We expect that auditor intuition, rooted in the subconscious, more likely reacts to impairment indicator risk than does auditor analytical thinking. Results from two different experiments support this expectation for less‐experienced audit seniors. These seniors are more likely to assess step‐zero impairment indicators as signaling potential impairment when prompted to thinkintuitivelyversusanalytically. In contrast, a third experiment finds that experienced seniors are more likely to assess step‐zero impairment indicators as signaling potential impairment when prompted to thinkanalyticallyversusintuitively. This is consistent with the more experienced but still non‐expert seniors possessing developed analytical thinking, but struggling to effectively use their intuition. Our results inform theory by suggesting under what conditions auditor intuition and analytical thinking produce differential risk sensitivity. Furthermore, our results inform practice, given regulators' stated focus on auditor skepticism and impairment assessments.
Splenic autotransplantation: a systematic review
Authors: Surendran Arthavan , Smith Marty , Houli Nezor , Usatoff Val , Spelman Denis , Choi Julian 
Published: October 2019

BackgroundSplenectomy is a surgical procedure indicated in a variety of medical conditions including trauma. Post‐operatively, there is a lifelong risk of developing overwhelming sepsis from encapsulated bacteria, most commonly due to Streptococcus pneumoniae. Splenic autotransplantation has been proposed as a method to recover splenic function in patients requiring splenectomy with otherwise normal spleens. This study aims to systematically review the literature to determine the efficacy of spleen autotransplantation.MethodsMEDLINE, PubMed and the Cochrane Library were searched for all studies assessing splenic autotransplantation (January 1947 to July 2018). Data were extracted on study characteristics, outcomes assessed, including spleen scintigraphy results, blood film counts and serum immunoglobulin (Ig) levels.ResultsData were obtained from 18 primary studies. All studies demonstrated return of regenerated spleen tissue in the majority of their patients (95.3%) on spleen scintigraphy. In 12 studies, 90.2% of patients had blood films return to normal following transplantation. Ig levels were shown to return to normal in all 12 studies where it was assessed. In 11 studies, 3.7% of patients had post‐operative complications. In five studies, 1.3% of patients had post‐operative infections in the follow‐up period.ConclusionSplenic autotransplantation is a safe procedure with minimal complications that can return splenic filtration function and Ig levels to normal ranges. It has not been confirmed whether autotransplantation provides meaningful protection against overwhelming post‐splenectomy infections.
Spontaneous activity rates and resting metabolism: Support for the allocation model of energy management at the among‐individual level
Authors: Biro Peter A. , Thomas Frédéric , Ujvari Beata , Adriaenssens Bart , Beckmann Christa 
Published: October 2019

AbstractDespite continuing interest in the proximate energetic constraints on individual variation in behavior, there is presently equivocal evidence for correlations between metabolism and behavior at the among‐individual level. Possible reasons for this include imprecise estimates of individual mean behavior and metabolism due to no repeated measures on one or more of the traits, analyses that do not take into account the labile nature of these traits and the uncertainty in individual estimates, and changing environmental conditions not accounted for. In this empirical study, we repeatedly measured activity rates and resting metabolic rates (RMR) of individual male mosquitofish over an extended period, lasting several months under constant laboratory conditions. Repeatability of each trait was significant (RMR: R = .41; activity: R = .72), indicating consistent variation among individuals, making covariance between them possible. Contrary to expectations, bivariate mixed model analysis revealed that more active individuals had lower RMR (r = −.58) after accounting for mass effects and other covariates. This result suggests that high activity rates require individuals to allocate less energy toward maintenance, and thus provides evidence for the “allocation” model of energy management. We suggest that it would be valuable to study whether and how behavior‐RMR correlations change over individual lifetime, a topic that has yet to be addressed.
