Interpersonal conflict at work and knowledge hiding in service organizations: the mediator role of employee well-being
Authors: Losada-Otálora Mauricio , Peña-García Nathalie , Sánchez Iván D. 
Published: November 2020

PurposeThis paper aims to explore the effects of interpersonal conflicts in the social workplace on various rationalized, knowledge-hiding behaviors in service organizations. This research also examines employee well-being as a mediator to explain the effects of interpersonal conflicts at work on knowledge-hiding behaviors.Design/methodology/approachFirst, relevant literature provided the theoretical basis for the conceptual model that links the core constructs of this research. A quantitative study collected data from 395 employees of a global consulting firm with a branch located in a developing country. Finally, an analysis of the structural equation modeling with MPlus 7 software tested the measurement and the structural model.FindingsThe results of this study suggest that interpersonal conflict at work influences knowledge-hiding and that employee’s well-being mediates this relationship. In other words, employees strategically choose what knowledge-hiding behaviors to use – such as evasion or “playing dumb” – to cope with the lack of well-being caused by high interpersonal conflicts in the workplace.Originality/valueAlthough contextual and individual factors may trigger knowledge-hiding behavior at work, the current literature has overlooked the combined effects of such factors, especially in service settings. Knowledge hiding in service organizations is a weakness that can lead to significant economic losses, especially in firms that are intensively knowledge-based. Thus, it is necessary to identify the antecedents of knowledge-hiding behavior to deter low performance in these organizations.
Procedure model to integrate digital elements into lean production systems
Authors: Rybski Christoffer , Jochem Roland 
Published: November 2020

Purpose
Industry 4.0 is one of the most used terms in the current industrial discussion. There are several perspectives and approaches related to Industry 4.0 so far, but no universal definition. Often-mentioned basic requirements to “implement” Industry 4.0 are lean and well-organized processes. In the past and still until today, a lot of companies try to implement lean production systems (LPS) according to the example of Toyota to realize a systematic approach to ensure well-organized processes. The process model aims to support organizations to integrate Industry 4.0 elements into LPS, regardless of the size of the organization. The purpose of this paper to describe a model as a first basis for further elaborations that could focus on the detailed design of each model-phases. Furthermore, the identified digital elements of Industry 4.0 build a first foundation to choose pilot projects related to existing challenges of the organizations LPS. In this context, especially the suitability of LPS and Industry 4.0 elements should be further investigated.

Design/methodology/approach
To investigate the current status regarding the realization of Industry 4.0 approaches and related challenges in the German industry, the two authors realized a survey with over 300 participants from different sectors and company sizes, using an online questionnaire. The results of the survey will be a part of this paper and a technology analysis, which was the outcome of an extensive literature analysis. The results were summarized in a model to integrate digital elements into existing LPS. Practitioners can use the process model as a first orientation to integrate industry 4.0 technologies into their existing LPS, based on specific challenges with their LPS processes.

Findings
Even if most of the participating German companies recognize Industry 4.0 as an important or very important topic, many of them do not consider themselves well prepared. The participants see huge challenges with regard to the needed qualifications and investments Industry 4.0 requires. In general, the companies hope to improve productivity and customer satisfaction to name two main objectives of the implementation of digital elements of Industry 4.0. In addition to the survey, a profound literature analysis was made and identified eight core digital elements. On this basis a milestone-based model to integrate these digital elements into existing LPS was developed.

Originality/value
This paper considers results from a study and analysis regarding the potentials of digital elements of Industry 4.0 for production system from different angles and introduces a model for integrating these elements.
Selling actors in multi-actor sales ecosystems: who they are, what they do and why it matters
Authors: Weretecki Patrick , Greve Goetz , Henseler Jörg 
Published: November 2020

Purpose
The purpose of this paper is to investigate selling actors in multi-actor sales ecosystems. When selling actors start taking over tasks that were formerly performed by salespeople, the distribution of tasks, allocation of responsibilities and finally the role of the salespeople changes. However, little is known about salespersons’ perceptions of selling actors’ identities and participation behavior in multi-actor sales ecosystems.

Design/methodology/approach
The authors conducted a World Café, a new qualitative method to the field of sales research, to obtain first data on selling actor identities in multi-actor sales ecosystems. Salespeople, who had the chance to observe and interact with more than 98,000 selling actors, disclosed their perceptions of selling actors’ participation behavior in a multi-actor sales ecosystem. Four different data sources were analyzed using qualitative content analysis to develop a comprehensive understanding of the topic and to test validity through the convergence of information from different sources.

Findings
Using identity theory, a salesperson–selling actor relationship/behavior typology for multi-actor sales ecosystems was developed. Eight different selling actor identities were identified: avoider, observer, receptive actor, prepper, expecter, savvy actor, challenger and coworker.

Originality/value
The typology provides researchers and managers with a tool to better understand and evaluate sales ecosystems. This knowledge can be used as a starting point for the reassessment of the knowledge, skills and abilities necessary for salespeople in multi-actor sales ecosystems and to improve their training and coaching. The firsthand experiences reported by the participants of the World Café enable salespeople to identify different selling actors faster and prepare fitting approaches for all selling actor identities.

Findings
COVID-19 has offered profound challenges to the goal of normalcy. Rise Above has adapted to meet the challenges.

Originality/value
The authors argue that COVID may also offer opportunities to build toward a more robust paradigm of normalcy within child welfare policy and practice.
Does corporate tax aggressiveness explain future stock price crash? Empirical evidence from France
Authors: HAMZA Taher , ZAATIR Elhem 
Published: November 2020

Purpose
This study aims to examine the impact of corporate tax aggressiveness on future stock price crash. It also tests the impact of corporate tax aggressivness in predicting stock price crash for a two-year forecast window.

Design/methodology/approach
The study sample consisted of 1,169 firm-years observations. The multivariate analysis uses three measures of stock price crash risk, as a dependent variable. The key variable is tax aggressiveness lagged by one period (one year) as all independent variables. As a robustness check, this paper uses alternate measures of earning management and a longer forecast window (two years) to predict stock price crash risk.

Findings
Tax aggressiveness activity is positively related to a firm-specific future stock price crash. Moreover, corporate tax aggressiveness predicts stock price crash risk for a long forecast window (two years). The findings are robust to a number of checks and have several policy implications.

Practical implications
The cost of continuing to accumulate bad news will be greater than the cost of revealing them. Thus, board of directors should encourage disclosure in order to reveal private news and then, to increase the amount of firm-specific information in returns. Another point is that tax aggressiveness behavior implies a risk to be perceived by the market as socially irresponsible, and may harm the firm reputation. This fact leads, in terms of portfolio management, to deter investment in firm-equity. Therefore, Investors should be cautious about the different risks of corporate tax aggressiveness.

Social implications
The accounting system in France, as in most European countries, relies upon codified rules and government requirement. Thus, our results provide some evidence of the effectiveness of the French laws and regulations in preventing indirectly earnings management from affecting stock price crash risk.

Originality/value
French companies are among the heavily taxed in Europe which makes France a particularly suitable context for studying tax aggressiveness issues. To the best of our knowledge, this study is the first in the french context, that document a signifcant and positive relation between tax aggressiveness and future crash risk. It focuses on the important role of corporate tax planning as a means of withholding bad news and its consequences in inflating stock prices.
COVID-19 health crisis and prevalence of anxiety among individuals of various age groups: a qualitative study
Authors: Ahmed Ammar , Aqeel Muhammad , Aslam Naeem 
Published: November 2020

Purpose
The monetary and psycho-social ramifications of the COVID-19 pandemic have been extensive and unimaginable around the globe. The purpose of this study was to have a psycho-social analysis of people confronting this situation and its impact in the situation of a health crisis on them.

Design/methodology/approach
In the current study, participants were divided according to their different backgrounds and professions based on the types of measures taken by the Pakistani government to limit the spread of the virus and people who are not disturbed by any of the measurement categories but are troubled by the coronavirus. The interviews based on five open-ended questions were conducted with the eight participants, comprising questions that helped participants in remembering and realizing the purpose of the interview in the mode of an open questioning. Phenomenological interpretative analysis was used to understand how participants make meaning of the phenomenon being studied, an in-depth analysis of the human subject was considered in its singularity, and personal accounts and experiences were noted regarding this pandemic.

Findings
The results indicated that the participant’s experiences were marked by stress, insecurity, anger, fear, anxiety, traces of painful emotions and a feeling of weakness. Also the prevalence of unknown precariousness and vulnerability of coronavirus aggravated the psychological frailness among people existing in an anxiety-prone situation created by the novel coronavirus. Confronted with these painful experiences, the participants however, used a variety of cognitive and behavioral efforts which needs to be strengthened by psychological care.

Research limitations/implications
This study based on qualitative method was performed on diverse socio-professional levels, giving an insight to what they are undergoing, their current fears, desires and their feeling. The outcome of this study reveals traces of uncertainty, anxiety, fears, insecurity and hidden imminent death from coronavirus, therefore highlighting a need for immediate psychological interventions.

Originality/value
This study explores the individual understanding regarding current coronavirus pandemic situation on subjective lived experiences and psychological health in an anxiety-prone context manifested by the health crisis created by the novel corona virus.
The effect of audit of outgoing leading officials’ natural resource accountability on environmental governance: evidence from China
Authors: Wu Xiting , CAO Qun , Tan Xiaoping , Li Liang 
Published: November 2020

Purpose
This paper aims to examine the relationship between the audit of outgoing leading officials' natural resource accountability and environmental governance, as well as the internal mechanism of audit of outgoing leading officials' natural resource accountability that plays a role in national environmental governance.

Design/methodology/approach
Based on city-level panel data from 2012 to 2015, this paper adopts a difference-in-difference model to examine the role of government audit in national governance from an environmental perspective. Furthermore, using a mediating effect model, the study sheds light on the internal mechanism of audit of outgoing leading officials’ natural resource accountability that plays a role in national environmental governance.

Findings
This paper finds that: the implementation of the audit of outgoing leading officials’ natural resource accountability has significantly improved the water quality of the pilot area, but its effects on waste gas and smoke are not obvious; environmental supervision partly plays a mediating role in the improvement of regional environmental governance by the audit of outgoing leading officials’ natural resource accountability; the audit of outgoing leading officials’ natural resource accountability can complement the incentive mechanism of promotion. The older the local officials are, the more obvious the effect of the audit of outgoing leading officials’ natural resource accountability on the environmental quality of the pilot areas is.

Originality/value
This paper reveals the role of government audit from the perspective of environmental governance. It provides empirical evidence for policy regarding the audit of outgoing leading officials' natural resource accountability.
Care pathways for people with intellectual disabilities who present with behaviours that challenge
Authors: Roy Ashok , Baker Peter , Carmichael Sue 
Published: November 2020

PurposeCare pathways are being increasingly used in the national health service to outline an anticipated programme of care in relation to a particular illness, condition or set of symptoms. The purpose of this paper is to inform those using the service of what they might expect within what time frame. They are designed to reduce variation in practice and allow optimal quality of care across a variety of care settings. Care pathways map out a patient’s journey, providing coordination of services for users. They aim to have: “the right people, doing the right things, in the right order, at the right time, in the right place, with the right outcome”.Design/methodology/approachThis paper outlines care pathways in relation to people with intellectual disabilities who present with behaviour that challenges.FindingsIt is likely that many people will have a lifelong need for support, so discharge from clinical services should only be considered if it is genuinely appropriate. Reductions in a person’s behaviours that challenge are likely to be a consequence of changes that have been made to the person’s environment and supports. Therefore, any reductions in the level or type of support that the person receives may lead to an escalation of the behaviour again.Originality/valueStandards in relation to care pathways are presented.
Commentary on a “unified approach to behaviours that challenge”: my freedom – the perspective of people with learning disabilities
Authors: Chapman Steve , Lillis Michael , Lamb Sammy , Clifton Matt , Clay Charlotte 
Published: November 2020

Purpose
As self-advocate leaders, the authors aim to present the perspective of people with learning disabilities on “Behaviour that Challenges: A Unified Approach”. Building on firsthand accounts which reveal compassion and cruelty in the health-care system, the authors propose ways of working, which confirm and add to the thinking in “A Unified Approach”, especially “Capable Environments”.

Design/methodology/approach
To ensure integrity, the authors engaged contributors with lived experience of admission to secure care after acting in ways that put themselves or others at risk. The authors included the perspective of people whose severe learning disabilities limit them to few or no words as best they could by interviewing their parents. The authors were supported and advised in the writing of this commentary while retaining full control throughout.

Findings
While recognising compassionate care, the authors suggest the provider’s power over a person’s life is a central reason for the care system’s vulnerability to the cruelty evident in firsthand accounts. The authors propose practical ways to offset this power. Firsthand accounts suggest the key features of capable environments are communication, valuing families and developing a valued, caring, well-trained workforce. Lived experience in workforce training and peer-support to individuals offer great potential to transform outcomes.

Originality/value
The perspectives of diverse contributors with learning disabilities bring lived experience insight to the challenges of “behaviour that challenges”. The authors aim to add value by blending lived experience viewpoints with the emotion of firsthand accounts of care. The insights of lived experience – too often a marginal consideration in health-care design – are presented here as central to care that fully achieves what people want and need.
Denoising of magnetotelluric data using K‐SVD dictionary training
Authors: Li Jin , Peng Yiqun , Tang Jingtian , Li Yong 
Published: November 2020

ABSTRACTMagnetotelluric is one of the mainstream exploration geophysical methods, which plays a vital role in studying deep geological structures and finding deep hidden blind ore bodies. The seriousness of human electromagnetic noise causes a large number of abnormal waveforms in the time series of measured magnetotelluric data, and the data can no longer objectively reflect the underground electrical distribution. In this work, we propose a magnetotelluric time series data processing method based on K singular value decomposition dictionary training. First, a training matrix and a to‐be‐processed matrix are built with the pending magnetotelluric signals. Then, let the K singular value decomposition dictionary training process the training matrix to obtain an over‐complete dictionary reflecting the characteristics of the pending signal. Lastly, orthogonal matching pursuit is combined with an over‐complete dictionary updated in real time to sparsely represent the to‐be‐processed matrix and remove human electromagnetic interference in the signal. Experimental results show that the method can update the over‐complete dictionary in real‐time according to the pending magnetotelluric signals, realize the self‐learning signal–noise separation of magnetotelluric signals, and effectively retain low‐frequency information. Compared with method of directions dictionary learning, remote reference method, and orthogonal matching pursuit method, the reconstructed data of the proposed method can more accurately reflect the underground electrical structure information.
