iScore: an MPI supported software for ranking protein-protein docking models based on a random walk graph kernel and support vector machines
Authors: Renaud Nicolas , Jung Yong , Honavar Vasant , Geng Cunliang , Bonvin Alexandre M.J.J. , Xue Li C. 
Published: October 2019

AbstractComputational docking is a promising tool to model three-dimensional (3D) structures of protein-protein complexes, which provides fundamental insights of protein functions in the cellular life. Singling out near-native models from the huge pool of generated docking models (referred to as the scoring problem) remains as a major challenge in computational docking. We recently published iScore, a novel graph kernel based scoring function. iScore ranks docking models based on their interface graph similarities to the training interface graph set. iScore uses a support vector machine approach with random-walk graph kernels to classify and rank protein-protein interfaces.Here, we present the software for iScore. The software provides executable scripts that fully automatize the computational workflow. In addition, the creation and analysis of the interface graph can be distributed across different processes using Message Passing interface (MPI) and can be offloaded to GPUs thanks to dedicated CUDA kernels.

Authors: Sener Eralp , Turk Irem , Yazar Isil , Karakoç Tahir Hikmet 
Published: October 2019

Purpose
The aviation industry has started environment friendly and also conventional energy independent alternative energy dependent designs to reduce negative impacts on the nature and to maintain its future activities in a clear, renewable and sustainable way. One possible solution proposed is solar energy. Solar-powered aerial vehicles are seen as key solutions to reduce global warming effects. This study aims to simulate a mathematical model of a solar powered DC motor of an UAV on MATLAB/Simulink environment.

Design/methodology/approach
Maximum power point tracking (MPPT) is a critical term in photovoltaic (PV) array systems to provide the maximum power output to the related systems under certain conditions. In this paper, one of the popular MPPT techniques, “Incremental Conductance”, is simulated with solar-powered DC motor for an UAV design on MATLAB/Simulink.

Findings
The cascade structure (PV cell, MPPT, buck converter and DC motor models) is simulated and tested under various irradiance values, and results are compared to the DC motor technical data. As a result of that, mathematical model simulation results are overlapped with motor technical reference values in spite of irradiance changes.

Practical implications
It is suggested to be used in real time applications for future developments.

Originality/value
Different from other solar-powered DC motor literature works, a solar-powered DC motor mathematical model of an UAV is designed and simulated on MATLAB/Simulink environment. To adjust the maximum power output at the solar cell, incremental conductance MPPT technique is preferred and a buck converter structure is connected between MPPT and DC motor mathematical model. It is suggested to be used in solar-powered UAV designs for future developments.
Stakeholder engagement toward value co-creation in the F&B packaging industry
Authors: Giacomarra Marcella , Crescimanno Maria , Sakka Georgia , Galati Antonino 
Published: October 2019

PurposeThe purpose of this paper is to explore how a food and beverage packaging company manages internal and external stakeholders to achieve sustainable innovation outcomes, as well as to contribute to the spread of sustainability paths along the supply chain, on which it operates.Design/methodology/approachA case study approach was chosen and applied multiple methods of semi-structured interviews and a documentation review.FindingsResults reveal a structured stakeholder relationship management, according to which the packaging company acts through a stakeholder engagement process to both acquire and share new knowledge to address stakeholder pressure. Co-creation models result in a winning strategy to exploit knowledge, above all in a supply chain context, where actors should act as a part of a strictly interlinked system, involving external stakeholders (also suppliers) and internal stakeholders in joint eco-innovation projects. The case study shows the potential strategic role of a packaging company in affecting relevant actors of the supply chain through the promotion of a sustainability culture.Research limitations/implicationsThe first limitation is linked to the chosen case study approach, which does not allow for results to be generalized. Future works could arrange panel data analysis to investigate in depth the behavior of several packaging companies regarding stakeholder relationship management.Practical implicationsManagerial implications mainly underline that, to fully address market stakeholder pressure, managers should recognize the relevance of acquiring and sharing new knowledge from external sources, without underestimating the need to integrate it with internal stakeholders (employees) for its exploitation.Originality/valueThe present work is original for the food and beverage industry, with specific attention on the packaging sector, which, until today, has been widely investigated regarding food and waste loss reduction strategies, but less often from the perspective of stakeholder relationship management in addressing sustainability.
Energy load forecasting: Bayesian and exponential smoothing hybrid methodology
Authors: Khorsheed Eman 
Published: October 2019

Purpose
The purpose of this study is to present a hybrid approach to model and predict long-term energy peak load using Bayesian and Holt–Winters (HW) exponential smoothing techniques.

Design/methodology/approach
Bayesian inference is administered by Markov chain Monte Carlo (MCMC) sampling techniques. Machine learning tools are used to calibrate the values of the HW model parameters. Hybridization is conducted to reduce modeling uncertainty. The technique is applied to real load data. Monthly peak load forecasts are calculated as weighted averages of HW and MCMC estimates. Mean absolute percentage error and the coefficient of determination (R2) indices are used to evaluate forecasts.

Findings
The developed hybrid methodology offers advantages over both individual combined techniques and reveals more accurate and impressive results with R2 above 0.97. The new technique can be used to assist energy networks in planning and implementing production projects that can ensure access to reliable and modern energy services to meet the sustainable development goal in this sector.

Originality/value
This is original research.
Lead by example? The dissemination of ethical values through authentic leader inspiration
Authors: Hattke Fabian , Hattke Judith 
Published: October 2019

PurposeThe purpose of this paper is to propose that leaders who promote ethical values authentically will be more effective in inspiring followers to behave ethically than inauthentic leaders. It further hypothesizes that authentic ethical inspiration by leaders will transform followers’ prosocial motivation so that they internalize their leader’s values and act accordingly.Design/methodology/approachThe study tests this moderated-mediation model based on survey data from 741 officers in the Federal Armed Forces Germany who are leaders and follower simultaneously.FindingsLeader authenticity moderates the relationship between leader ethical influence and follower ethical behaviors. The effect is significant and substantial. Leader ethical influence has a significant, yet marginal effect on follower prosocial motivation, which, in turn, strongly relates to follower ethical behaviors.Research limitations/implicationsAlthough leader authenticity is a value in itself, it says little about the contents of leaders’ ethical values. Thus, future research should not confound authentic leadership with ethical leadership. Prosocial motivation is a comparatively stable characteristic of individuals, which is rather resilient against leader influence.Practical implications“Softer” means of leader influence are effective in the coercive context of public command-and-control organizations. By cascading down the hierarchy, ethical values disseminate throughout the organization. The study draws these conclusions within the limitations of a cross-sectional analysis.Originality/valueThis study is the first to investigate the moderating role of perceived leader authenticity in the relationship between leader ethical inspiration and follower ethical behaviors.
Port marketing as manifestation of sustainable marketing in a B2B context
Authors: Lavissière Alexandre , Mandják Tibor , Hofmann Julian , Fedi Laurent 
Published: October 2019

Purpose
Previous literature dealing with sustainable marketing in a B2B context is mostly limited to spot measures on an environmental, economic or social layer. Thus, the purpose of this paper is to exemplify how seaports as powerful economic business networks can facilitate multi-layered sustainability.

Design/methodology/approach
The authors integrate multiple case studies to pursue an inductive research approach to derive general patterns based on empirical observations.

Findings
Operationalizing the concept of a port community enables the authors to show how seaports not only facilitate multi-layered sustainability but also mutually interact. Hence, port sustainability can be achieved through and by a port community.

Research limitations/implications
The conceptualization of the interplay between port community and multi-layered sustainability contributes to the business and industrial marketing literature in general and to the yet hitherto scarce port marketing literature in particular. Future research should go beyond this initial conceptualization by gathering further empirical research.

Practical implications
The study outlines how strengthening interactions among port management stakeholders (i.e. business and non-business actors such as port authorities and policymakers) might lead to higher economic success and societal welfare by pooling yet hitherto independent resources.

Originality/value
To the best of the authors’ knowledge, this is the first study to define how the concept of a holistic port community can facilitate sustainability acted out on its three pillars and how both concepts interact.
Fixing another firm’s mistake: how should recovering firms react?
Authors: Bahmani Navid , Jin Zhenyu , Ghose Sanjoy 
Published: October 2019

Purpose
While within-firm service failure and recovery have been studied extensively, the context in which a service failure at one firm “spills over” and provides an opportunity for an external firm (a subsequent service provider) to recover (compensate) a customer has received limited attention. This study aims to examine how the extent of a service failure plays a role in how external firms should shape their recovery efforts, and how customers’ evaluations of the recovering firm and their feelings of unhappiness are affected.

Design/methodology/approach
A pretest conducted on MTurk gauged participants’ perceptions of equitability of the external firm’s recovery effort. In the main study, a 3 × 3 between-subjects experiment examined the effects of failure extent and external recovery type on evaluations of the recovering firm and reduced feelings of unhappiness.

Findings
It is found that equity judgments remain consistent in the external recovery context; transferred negative affect is able to be mitigate only in low-failure scenarios, and customers’ evaluations of the external firm increase only in high-failure scenarios.

Research limitations/implications
The use of hypothetical scenarios, as opposed to the employment of a field study, is the primary limitation of the study.

Originality/value
This research finds that external firms can reap the benefits of another firm’s service failure by offering no-cost recoveries, rather than ones that carry some form of cost.
A hierarchical typology of scholarly information units: based on a deduction-verification study
Authors: Yu Liangzhi , Fan Zhenjia , Li Anyi 
Published: October 2019

PurposeThe purpose of this paper is to lay a theoretical foundation for identifying operational information units for library and information professional activities in the context of scholarly communication.Design/methodology/approachThe study adopts a deduction-verification approach to formulate a typology of units for scholarly information. It first deduces possible units from an existing conceptualization of information, which defines information as the combined product of data and meaning, and then tests the usefulness of these units via two empirical investigations, one with a group of scholarly papers and the other with a sample of scholarly information users.FindingsThe results show that, on defining an information unit as a piece of information that is complete in both data and meaning, to such an extent that it remains meaningful to its target audience when retrieved and displayed independently in a database, it is then possible to formulate a hierarchical typology of units for scholarly information. The typology proposed in this study consists of three levels, which in turn, consists of 1, 5 and 44 units, respectively.Research limitations/implicationsThe result of this study has theoretical implications on both the philosophical and conceptual levels: on the philosophical level, it hinges on, and reinforces the objective view of information; on the conceptual level, it challenges the conceptualization of work by IFLA’s Functional Requirements for Bibliographic Records and Library Reference Model but endorses that by Library of Congress’s BIBFRAME 2.0 model.Practical implicationsIt calls for reconsideration of existing operational units in a variety of library and information activities.Originality/valueThe study strengthens the conceptual foundation of operational information units and brings to light the primacy of “one work” as an information unit and the possibility for it to be supplemented by smaller units.
Reframing integration
Authors: Bronstein Jenny 
Published: October 2019

Purpose
The purpose of this paper is to explore a different perspective about the role that information plays in the integration process of migrant workers by exploring the views and opinions of individuals and organizations that work with these communities on a daily basis. The study proposes a new perspective of Ager and Strang’s framework of integration by looking at its different elements through the perspective provided by Gibson and Martin’s (2019) concept of information marginalization and Dervin’s sense-making notion of resistance.

Design/methodology/approach
Ten intermediaries working with migrants were interviewed using semi-structure interviews. They were analyzed using an integrative approach of deductive and inductive content analysis and rendered categories drawn from the theoretical frameworks and categories that emerged from the data.

Findings
The content analysis of the data revealed that information marginalization is characterized by the lack of cultural knowledge and lack of language proficiency that impact the migrants abilities to fulfill their everyday needs, experience a safe and stable environment. Information marginalization results in migrants experiencing self-protective behaviors such as secrecy and an inability to trust information sources that are not contextualized by insiders. Findings show that information resistance can be overcome by making information available in relevant formats and distributed through trusted sources.

Social implications
The study revises the notion of information marginalization by trying to understand the social and cultural gap that from both sides of the issues of integration.

Originality/value
The study presents a different perspective of the role of information in the integration process of migrants by examining the views and opinions of intermediaries working with these populations. Also, the study reframes existing notions of information marginalization and resistance by addressing both sides of the cultural and social gap embodies marginalization.
From hindrance to challenge
Authors: Li Ying , Pan Ting , Zhang Nan (Andy) 
Published: October 2019

PurposeThis paper is to investigate how employees respond to information security policies (ISPs) when they view the policies as a challenge rather than a hindrance to work. Specifically, the authors examine the roles of challenge security demands (i.e. continuity and mandatory) and psychological resources (i.e. personal and job resources) in influencing employees’ ISP non-compliance.Design/methodology/approachApplying a hypothetical scenario-based survey method, the authors tested our proposed model in six typical ISPs violation scenarios. In sum, 347 responses were collected from a global company. The data were analyzed using partial least square-based structural equation model.FindingsFindings indicated that continuity and mandatory demands increased employees’ level of perseverance of effort, which, in turn, decreased their ISPs non-compliance intention. In addition, job resources, such as the trust enhancement gained from co-workers and the opportunities for professional development, enhanced the perseverance of effort.Practical implicationsThe findings offer implications to practice by suggesting that organizations should design training programs to persuade employees to understand the ISPs in a positive way. Meanwhile, organizations should encourage employees to invest more personal resources by creating a trusting atmosphere and providing them opportunities to learn security knowledge and skills.Originality/valueThis study is among the few to empirically explore how employees respond and behave when they view the security policies as challenge stressors. The paper also provides a novel understanding of how psychological resources contribute to buffering ISP non-compliance.
The reduction of production lead time using holonic manufacturing: experiment and analysis
Authors: Torres-Palacio Patricio 
Published: October 2019

PurposeIn modern industrial processes, the need of reducing lead time is imperious. This goal is pursued by “Holonic” structures, which are systems based on a network of collaboration. The purpose of this paper is to appraise the possible benefits, in terms of production duration, of such organizations compared to non-holonic arrangements. In addition, this analysis represents virtual teams, which are a significant and strategic attribute of holonic manufacturing systems.Design/methodology/approachThe experiment performed in this paper is a simulation of an automobile assembly process under both a holonic and a non-holonic structure to observe lead times and the distinctive characteristics of each organization. Other targets of this research are to monitor the advantages that either strategy may offer in terms of efficiency and to examine a possible model of how virtual teams can be used in holonic networks.FindingsThe findings are unexpected. An initial expectation might lead to the belief that, given the better coordination and communication of holonic networks, lead times would be diminished. This experiment, utilizing virtual teams of university students, indicated otherwise.Research limitations/implicationsIt should be noticed, however, that future experiments in real manufacturing assembly processes are recommended to complement the findings of this study.Originality/valueThe management of lead times is indeed a complex task that includes a diversity of variables. Holonic structures should balance several factors that might play a role in lead times and ultimately in the success of a project. An original experiment with the participation of many universities in different countries is presented in this study. The exposure of global characteristics of modern manufacturing structures constitutes the main value of this research.
Proximities at the aerospace complex of São José dos Campos (Brazil)
Authors: Cintra Paulo Roberto , Costa Janaina , Sica de Campos André Luiz 
Published: October 2019

Purpose
The formation of an aerospace complex in São José dos Campos (SP-Brazil) reflects a process of path dependence, which has favored sectorial technological development and innovation. In this sense, the purpose of this paper is to investigate the pattern of relationships established between Embraer, the Technological Institute of Aeronautics, the National Institute of Space Research (INPE) and the institutes linked to the Aerospace Technical Center (CTA).

Design/methodology/approach
Using patents as a proxy for inventive activity, the authors carried out social networks analysis based on collaboration maps elaborated considering co-assignees in institutional patents.

Findings
Over time, Embraer became the main inventor of patentable technologies and a central player in the network of the aerospace complex at São José dos Campos.

Research limitations/implications
Several public institutions analyzed pertain to the Brazilian Ministry of Defence. Therefore, inventive activity may be confidential, which implies a limitation in the analysis.

Originality/value
With acquisition of Embraer by the US company Boeing, there could be a loss of the company's technical capacity in product development. The paper argues that the aerospace complex itself might also be impacted, considering that Embraer is the most relevant inventor of patentable knowledge locally in recent decades.
Shape-driven control of layer height in robotic wire and arc additive manufacturing
Authors: Xu Bohao , Tan Xiaodong , Gu Xizhi , Ding Donghong , Deng Yuelin , Chen Zhe , Xu Jing 
Published: October 2019

Purpose
Once an uneven substrate is aligned, traditional control theories and methods can be used on it, so aligning is of great significance for the development of wire and arc additive manufacturing (WAAM). This paper aims to propose a shape-driven control method for aligning a substrate with slopes to expand the application of WAAM.

Design/methodology/approach
A substrate with slopes must be aligned by depositing weld beads with slopes. First, considering the large height differences of slopes, multi-layer deposition is needed, and the number of layer of weld beads must be ascertained. Second, the change in the deposition rate is controlled as a ramp function to generate weld beads with slopes. Third, the variation of the deposition rate must be fine-tuned to compensate for the deviation between the actual and theoretical layer heights at the deposition of each layer. Finally, the parameters of the ramp functions at the deposition of each layer are determined through an optimization method.

Findings
First, to model the response function of layer height to deposition rate, the experiments are conducted with the deposition rate jumping from 4 to 8 mm/s and from 8 to 4 mm/s. When the deposition rate jumps from 4 to 8 mm/s and from 8 to 4 mm/s, the difference in the height of each layer decreases as the number of layer increases. Second, the variation of the deposition rate can be fine-tuned based on the deviation between the measured and theoretical layer heights because the variation of the deposition rate is proportional to the layer height when the initial and end deposition rates are near 4 or 8 mm/s, respectively. Third, the experimental results demonstrate that the proposed method is effective for single-layer aligning and aligning a substrate with one or more slopes.

Originality/value
The proposed method can expand the application of WAAM to an uneven substrate with slopes and lays the foundation for aligning tasks focused on uneven substrates with more complex shapes.
