Novel multiscale insights into the composite nature of water transport in roots
Authors: Couvreur Valentin , Faget Marc , Lobet Guillaume , Javaux Mathieu , Chaumont François , Draye Xavier 
Published: June 2017

Summary-MECHA is a novel mathematical model that computes the flow of water through the walls, membranes and plasmodesmata of each individual cell throughout complete root cross-sections, from a minimal set of cell level hydraulic properties and detailed root anatomical descriptions.-Using the hydraulic anatomical framework of the Zea mays root reveals that hydraulic principles at the cell and root segment scales, derived independently by Katchalsky and Curran [1967] and Fiscus and Kramer [1975], are fully compatible, irrespective of apoplastic barriers leakiness.-The hydraulic anatomy model accurately predicts empirical root radial permeability (kr) from relatively high cell wall hydraulic conductivity and low plasmodesmatal conductance reported in the literature.-MECHA brings novel insights into contradictory interpretations of experiments from the literature by quantifying the impact of intercellular spaces, cortical cell permeability and plasmodesmata among others on root kr, and suggests new experiments efficiently addressing questions of root water relations.SymbolsKPDsingle plasmodesma hydraulic conductancekrroot radial hydraulic conductivitykwcell wall hydraulic conductivityLpcell plasma membrane hydraulic conductivity
Plurality in environmental supply chain mechanisms
Authors: Paulraj Antony , Blome Constantin 
Published: June 2017

PurposeThe environmental management of supply chains has become increasingly relevant in the recent era. Extant research proposes two main forms of mechanisms – collaboration and evaluation – for environmental supply chain management. Despite the wide use of these mechanisms and the empirical insight into the fact that they could be adopted simultaneously, it is unknown if, and, at which levels, environmental collaboration (EC) and environmental evaluation (EE) could be complementary or substitutionary in nature. Therefore, the purpose of this paper is to gain a clear understanding into the plural forms of these mechanisms.Design/methodology/approachThe transaction cost economics and relational exchange theory are used to ground the research hypotheses. The results are based on survey data collected from 145 US manufacturing firms. The authors employ polynomial regression as well as the response surface methodology to test the proposed hypotheses.FindingsThe results suggest that EC and EE can have an intriguing effect depending on the outcome measure. Specifically, the authors find the effects in the economic and the environmental/social domains to be significantly different.Originality/valueWhile scholars acknowledge that collaboration and evaluation could act as complements, extant research does not propose and test models that specifically capture complementary and substitutionary nature of these mechanisms. Accordingly, the study makes the first attempt to empirically test for the effects of the simultaneous pursuit of EC and EE.
The development of cultural heritage in Gozo, and its potential as a tourism niche
Authors: Borg Daniel 
Published: June 2017

PurposeThe purpose of this paper is to present a case study on the development of the cultural heritage sector on the island of Gozo in the Maltese archipelago. The studying of these relationships is very important to maximise the impact of the cultural heritage sector on tourism. The importance of the development of cultural tourism as a specific niche has been consistently recognised (Boissevain, 1994; Ministry for Tourism and Culture, 2007; Ministry for Tourism Culture and the Environment, 2016; Ministry for Tourism, 2014).Design/methodology/approachA case study methodology is adopted. The findings have been sourced mainly through secondary data such as official publications and materials available publicly, and through the author’s in-depth knowledge of the socio-cultural context of Gozo.FindingsThe paper’s main outcome is that the success of the cultural heritage sector in Gozo can be attributed to the close collaboration that exists between the Ministry for Gozo (responsible for Gozitan affairs) and non-governmental organisations (NGOs). While a culture of mistrust towards state institutions is generally prevalent among Gozitans (Azzopardi, 2015), the level of collaboration between the Ministry for Gozo and NGOs, may tend to show that Gozitans are more keen to trust state institutions run by the same Gozitans.Originality/valueThis paper analyses the underlying relationships in the cultural heritage sector on the island of Gozo. This is very important to continue building up on this niche as an added value to the tourism sector in Gozo.
Knowledge management and professional experience: the uneasy dynamics between tacit knowledge and performativity in organizations
Authors: Garrick John , Chan Andrew 
Published: June 2017

Purpose
This paper interrogates the relationships between tacit knowledge (of professionals) and performance measurement regimes (of post-modern organizations). Drawing on Polanyi’s (1958, 1968) ideas about tacit knowledge and Lyotard’s (1984) theory of performativity with regard to criteria such as profit-performance the applicability and relevance of tacit, working knowledge in the internet age is assessed. The paper examines: the effects of context on knowledge management (KM); tacit knowledge and performativity around the production, validation and assessment of knowledge within organizations; KM and the mercantilization of knowledge and critical questions as to how performativity impacts tacit knowledge and KM in the digital era.

Design/methodology/approach
The paper deconstructs popular and fashionable narratives around tacit knowledge and KM to critically appraise approaches to knowledge construction and transfer in contemporary and commercial contexts. The study draws on various specific critical incidents in commercial practice to assess where (and why) things went wrong with KM practices in the aftermath of the global financial crisis and in more recent attempts at large scale corporate fraud.

Findings
KM should not trade exclusively in instrumentalized, performative knowledge. Tacit knowledge involves a sense of what is going on and this is not easily measured or codified. Experiential understanding of what is required when engaging with clients, colleagues, senior partners, other businesses (and cultures) and the political contexts in which employees work is central to tacit knowledge. So too are performance measures and reward systems and herein lies the “uneasy dynamic”. The nature of any transfer of tacit knowledge is problematic, but such employee know-how remains critical to organizational performance and validating the use-value of knowledge for the purposes of KM.

Originality/value
Researchers have used the theories of Polanyi and Lyotard, but rarely combined them to investigate KM practices critically in post-modern organizations. By using the two theories, this paper critically examines the contemporary construction of tacit knowledge from perspectives that include the different discourses and localized practices through which it is produced and consumed.
The effect of compliance knowledge and compliance support systems on information security compliance behavior
Authors: Kim Sang Soo , Kim Yong Jin 
Published: June 2017

Purpose
The purpose of this paper is to understand from the knowledge management perspective how the mechanism of different voluntary compliance behaviors works and how information technology is used for compliance management in corporate settings where privacy and security issues are getting critical due to the advancement of big data and artificial intelligence.

Design/methodology/approach
In this study, the authors propose a structural model based on the theory of planned behavior and the IT relatedness theory that behavioral belief about compliance and social pressure affect compliance knowledge and compliance intention, and compliance knowledge partially mediates the impact of both independent variables on compliance intention. The authors surveyed with a structured questionnaire 975 employees of a major Korean energy company, S-OIL, which deploys a compliance support system. The respondents are classified into two groups: an Active IT Utilization Group and a Passive IT Utilization Group.

Findings
The results of our empirical examination show that compliance intention belief and social pressure influence compliance intention, and further, that compliance behavior is mediated by compliance knowledge – in both the active IT utilization group and the passive IT utilization group. However, the significance of each path coefficient, R square and the mediation effect in Model 1 (passive IT utilization group) are obviously a poor contrast to Model 2 (active IT utilization group). Also, the path from behavioral belief to compliance knowledge and social pressure to compliance knowledge show a significant moderating effect of IT utilization level.

Originality/value
This paper aims to promote more effective voluntary compliance behavior by increasing the understanding of the impact differences of the preceding factors, and the ways in which those are related to the knowledge management practice in terms of both knowledge itself and its support systems, i.e. compliance support system.
A design approach for process-based knowledge management systems
Authors: Sarnikar Surendra , Deokar Amit V. 
Published: June 2017

Purpose
This paper presents a design approach for process-based knowledge management (PKM) systems that can support knowledge-intensive processes where effective task execution is highly reliant on the knowledge and expertise of participants executing the tasks. The proposed design approach includes design methods and kernel theories governing the design of PKM systems and can also be easily integrated with existing systems analysis and design techniques.

Design/methodology/approach
The design science research methodology is used to design and develop the artifact which includes the overall PKM design approach. Information systems design theory is used as a high-level framework to develop and structure the design approach. Relevant design methods and behavioral theories are reviewed to identify kernel theories that guide the design and development of PKM systems. The design approach consists of meta-requirements for PKM systems and design processes to achieve the meta-requirements. A feasibility study is conducted to evaluate the feasibility of the proposed approach.

Findings
The design approach presented in this paper can guide system analysts and system developers in the design of knowledge management systems for supporting knowledge-intensive processes. The paper also includes a comprehensive design theory for PKM systems consisting of meta-requirements and a synthesis of various kernel theories into actionable design procedures. The proposed procedures include knowledge requirements modeling, knowledge flows modeling and knowledge and process performance modeling procedures. The feasibility study indicates that the PKM approach can be more useful and effective than solely using unified modeling language (UML)-based systems analysis and design techniques for the design of PKM systems.

Research limitations/implications
An implication to information systems design research is the feasibility of developing a specialized design approach that incorporates significant domain knowledge to solve complex information system design problems. An implication to practice is the significant potential to improve productivity and effectiveness of systems analysts and designers in developing PKM systems. A limitation is the small sample size of the feasibility study used to evaluate the ease of use and utility of the design approach.

Originality/value
The study makes a unique contribution by proposing a design approach that integrates business process and knowledge management considerations. The approach is particularly valuable because of the focus on integration with existing systems analysis and design techniques, thus allowing for easier adoption.
Work-family conflict: differences across generations and life cycles
Authors: Bennett Misty M. , Beehr Terry A. , Ivanitskaya Lana V. 
Published: June 2017

Purpose
The purpose of this paper is to examine work-to-family conflict and family-to-work conflict, taking into account generational cohort and life cycle stage differences.

Design/methodology/approach
Survey participants (428 employed individuals with families) represented different generations and life cycles. Key variables were work/family characteristics and centrality, work-family and family-work conflict, and age.

Findings
Generational differences in both directions were found. Gen X-ers reported the most work-family conflict, followed by Millennials and then Baby Boomers. Baby Boomers exhibited family-work conflict the most, followed by Gen X-ers, and then Millennials, a surprising finding given generational stereotypes. Some of these differences remained after controlling for children in the household (based on life cycle stage theory) and age. Millennials were highest in work centrality, whereas Baby Boomers were highest in family centrality. Employees with children ages 13-18 reported the most work-family conflict, and employees with children under the age of six reported the most family-work conflict.

Research limitations/implications
This study found that generation and children in the household make a difference in work-family conflict, but it did not support some of the common generational stereotypes. Future studies should use a time-lag technique to study generational differences. To reduce work-family conflict, it is important to consider its directionality, which varies across generations and life cycle stages.

Practical implications
This informs organizations on how to tailor interventions to help employees balance work/life demands.

Originality/value
This study is the first to simultaneously examine both generation and life cycle stage (children in the household) in regard to work-family conflict.
Effects of platform quality requirement on sellers
Authors: Hou Huijun , Cheng Xiaoying 
Published: June 2017

Purpose
The purpose of this paper is to study the effects of the requirement on product quality and refund (return service charge).

Design/methodology/approach
The authors set a minimum product quality level for platform to study the effects of the minimum product quality level on product quality and refund for risk-neutral sellers and risk-averse sellers, respectively.

Findings
For the risk-neutral sellers whose optimal product quality level is lower than the minimum level will improve the product quality to the minimum required level. However, under a certain condition with the requirement the sellers will increase refund. Similar results are found when uncertainty is incorporated into demand and return quantity. In addition, how the sellers’ optimal refund is affected by market parameters and market volatile factors is discussed. Specially, the correlation between the uncertainty of the demand and the return quantity affects sellers’ optimal decision of return service charge in many ways.

Originality/value
The obtained results can provide operational managers in reality with valuable suggestions in quality management for platform.
The unexpected cybernetics life of collectivities: the combinatory systems approach
Authors: Mella Piero 
Published: June 2017

PurposeThe purpose of this study is to show how simple “collectivities” of non-interconnected similar agents, which the author has termed “combinatory systems” and which produce analogous micro behaviors, reveal very interesting forms of micro and macro behaviors and effects attributable to a cybernetic mechanism the author shall call “micro-macro feedback”. On the one hand, the macro behavior of the system as a whole derives from the “combination” of the analogous micro behaviors or effects of the agents, and on the other hand, the macro behavior determines, conditions or directs the subsequent micro behavior, thereby creating observable effects and patterns in the collectivity.Design/methodology/approachThis paper proposes a new combinatory system theory (CSysT) by constructing a formal model that explains a vast group of phenomena produced by the cybernetic behavior of the collectivity as if an internal organizer were regulating the micro dynamics of agents, producing self-organization, synchronization, path dependence and chaos.FindingsIn addition to illustrating the CSysT, this study also proposes a new and powerful tool to simulate combinatory systems: the “combinatory automaton”. This is composed of a lattice, each of whose cells contains a variable representing the state of an agent. The value of each cell at each time depends on a synthetic global variable whose values derive from some operations carried out on the values of the cells and that represents the synthetic state of the automaton. The micro-macro feedback connects the analytical values of the cells and the synthetic state of the automaton.Practical implicationsThe CSysT suggests how to control combinatory systems through external actions aimed at making the macro and micro behaviors conform to the desired behaviors. The control is carried out through suitable strengthening or weakening actions, which operate by acting directly on the macro behavior – the author will define this as macro or external control – or by influencing the micro behaviors; in this case, the control will be called micro or internal control. The macro-level control is achieved through strengthening or weakening actions aimed at modifying some recombining factor. Instead, the micro-level control acts on the necessitating factors.Originality/valueThe CSysT is original and represents an effective tool for observing collective behavior. Combinatory systems are not easily recognizable; nevertheless, they are widely diffused and produce most of the social and economic collective phenomena involving the accumulation of objects, the spread of features or information, the pursuit of a limit and the achievement of general progress as the consequence of the individual pursuit of particular interests.
Describing a principles-based approach to developing and evaluating peer worker roles as peer support moves into mainstream mental health services
Authors: Gillard Steve , Foster Rhiannon , Gibson Sarah , Goldsmith Lucy , Marks Jacqueline , White Sarah 
Published: June 2017

Purpose
Peer support is increasingly being introduced into mainstream mental health services internationally. The distinctiveness of peer support, compared to other mental health support, has been linked to values underpinning peer support. Evidence suggests that there are challenges to maintaining those values in the context of highly standardised organisational environments. The purpose of this paper is to describe a “principles-based” approach to developing and evaluating a new peer worker role in mental health services.

Design/methodology/approach
A set of peer support values was generated through systematic review of research about one-to-one peer support, and a second set produced by a UK National Expert Panel of people sharing, leading or researching peer support from a lived experience perspective. Value sets were integrated by the research team – including researchers working from a lived experience perspective – to produce a principles framework for developing and evaluating new peer worker roles.

Findings
Five principles referred in detail to: relationships based on shared lived experience; reciprocity and mutuality; validating experiential knowledge; leadership, choice and control; discovering strengths and making connections. Supporting the diversity of lived experience that people bring to peer support applied across principles.

Research limitations/implications
The principles framework underpinned development of a handbook for a new peer worker role, and informed a fidelity index designed to measure the extent to which peer support values are maintained in practice. Given the diversity of peer support, the authors caution against prescriptive frameworks that might “codify” peer support and note that lived experience should be central to shaping and leading evaluation of peer support.

Originality/value
This paper adds to the literature on peer support in mental health by describing a systematic approach to understanding how principles and values underpin peer worker roles in the context of mental health services. This paper informs an innovative, principles-based approach to developing a handbook and fidelity index for a randomised controlled trial. Lived experiences of mental distress brought to the research by members of the research team and the expert advisors shaped the way this research was undertaken.
Customer-centered innovation: improving the odds for success
Authors: Leavy Brian 
Published: June 2017

Purpose
This masterclass examines how customer-centric marketing, using new perspectives developed by Clayton Christensen and others, can guide new product and service innovation. Christensen’s Jobs Theory revolves around the observation that “customers don’t buy products or services,” but rather “pull them into their lives to make progress” in some way that is particularly valuable to them.”

Design/methodology/approach
Two recent books are discussed in detail– Competing Against Luck: The Story of Innovation and Customer Choice (2016), by Christensen and co-authors Taddy Hall, Karen Dillon and David Duncan and Sense & Respond: How Successful Organizations Listen to Customers and Create New Products Continuously (2017) by design and innovation experts, Jeff Gothelf and Josh Seiden

Findings
In coming to view innovation through the lens of Jobs Theory, what you see is not so much the customer at the center of the innovation universe, but “the customer’s Job to Be Done,”which “may seem like a small distinction, but, in reality, “it changes everything.”

Practical Implications
Identifying a well-defined Job to Be Done offers a kind of innovation blueprint which is different’ from the traditional marketing concept of “needs” because of the ‘much higher degree of specificity required to identify precisely what it is you are trying to solve for in particular use-case contexts.

Originality/value
When applied astutely, the concept of “Job to Be Done”can improve a company’s track record at new product or service introduction. For the first time it gives managers and other corporate leaders a guidebook for making innovation initiatives more likely to be successful.
