This research presents an ontological model, to communicate the impact of dynamic preconditions for peri-urban communities. As such, this paper approaches perturbation communities as social-complex-adaptive-systems.

Previous assessment of dynamic preconditions have typically been based on top-down approaches. Through the lens of social-complex-adaptive and systemic design approaches (requiring a range of different disciplines), this work focuses on providing a broader view towards periurban research. The methodological approach involved academic literature, fieldwork observations, in-depth discussions with community, government, experts and research groups, focusing on a region called “Xochimilco” on the outskirts of Mexico City, a unique pre-Hispanic, Aztec ecosystem. This evolving man made agricultural/ecological structure of island plots, still provides environmental services to Mexico City. This region provides the basis of the research and subsequent ontological model. Ontology, in this instance, refers to the nature of being within a range of constraining dynamic forces relating to resilient behaviors of the current Xochimilco perturbation ecosystem.

Xochimilco can be considered as a longitudinal phenomenon that contributed to the understanding of observable resilient and precondition elements between the past and present of a living complex-adaptive-system.

The research has provided a better understanding of community resilience through preconditions, contributing towards preparation of environmental change and future urbanization. To this end, the research focused on visualizing key dynamics elements for communities attempting to absorb new urban conditions (being continuously pushed into it).

The outcomes of this research have provided specific systemic, bottom up approaches with ontological modeling to assist with visualizing and understanding intangible dynamic conditions that impact high complex areas of perturbation regions.

This research paper aims to analyze the scientific and grey literature on Quality 4.0 and zero-defect manufacturing (ZDM) frameworks to develop an integrated quality 4.0 framework (IQ4.0F) for quality improvement (QI) based on Six Sigma and machine learning (ML) techniques towards ZDM. The IQ4.0F aims to contribute to the advancement of defect prediction approaches in diverse manufacturing processes. Furthermore, the work enables a comprehensive analysis of process variables influencing product quality with emphasis on the use of supervised and unsupervised ML techniques in Six Sigma’s DMAIC (Define, Measure, Analyze, Improve and Control) cycle stage of “Analyze.”

The research methodology employed a systematic literature review (SLR) based on PRISMA guidelines to develop the integrated framework, followed by a real industrial case study set in the automotive industry to fulfill the objectives of verifying and validating the proposed IQ4.0F with primary data.

This research work demonstrates the value of a “stepwise framework” to facilitate a shift from conventional quality management systems (QMSs) to QMSs 4.0. It uses the IDEF0 modeling methodology and Six Sigma’s DMAIC cycle to structure the steps to be followed to adopt the Quality 4.0 paradigm for QI. It also proves the worth of integrating Six Sigma and ML techniques into the “Analyze” stage of the DMAIC cycle for improving defect prediction in manufacturing processes and supporting problem-solving activities for quality managers.

This research paper introduces a first-of-its-kind Quality 4.0 framework – the IQ4.0F. Each step of the IQ4.0F was verified and validated in an original industrial case study set in the automotive industry. It is the first Quality 4.0 framework, according to the SLR conducted, to utilize the principal component analysis technique as a substitute for “Screening Design” in the Design of Experiments phase and K-means clustering technique for multivariable analysis, identifying process parameters that significantly impact product quality. The proposed IQ4.0F not only empowers decision-makers with the knowledge to launch a Quality 4.0 initiative but also provides quality managers with a systematic problem-solving methodology for quality improvement.

Being acquainted with both lean and action learning in theory and in practice, this study finds that the theoretical complementarity of these two research streams has traditionally been underexploited. In this conceptual paper, this study aims to advance the theoretical understanding of lean by exploring the complementarity of lean thinking and action learning leading to a proposed integrated theory of these two research streams. Target audience is the operations management research community.

By deliberately adopting a process of theorising, this paper explores, reflects upon and combines individual experiences of researching, teaching and engaging in lean and action learning as operations management scholars.

Having taken a gemba walk through the literature and practices of lean and action learning, this study views and notices a systematic and complementary relationship between the two domains. The overlapping theoretical and practical complementarities of lean and action learning suggest that these two research streams are ripe for synthesis into an integrated theory. This finding provides an opportunity to (1) progress towards an integrative design of interventions leading to more sustainable lean system adoptions and (2) add new depth to our theoretical explanation of the success and failures of lean system adoptions.

This paper contributes an original integrated theory perspective on lean and action learning.

The purpose of this article is to aid conceptualization of social well-being at work by identifying its components in a contemporary office context, so adequate measures can be developed to monitor social well-being and to assess the impact of interventions in the workplace.

This study used existing interview data from recent post-occupancy evaluations of two large activity-based flexible offices in the Dutch public sector. Data-driven concept mapping of 182 different employees' statements on social aspects of well-being was used to find communalities in their perceptions.

From the data 14 key concepts emerged referring to employees' social needs, reactions to (anti-)social behaviour of others and perceived social affordances of the work environment. Contrary to established theory, social well-being appeared to be a context-bound phenomenon, including components of both short-term hedonic and long-term eudaimonic well-being.

The findings serve as an inductive source for the further development of adequate measures of social well-being at work. Limitations concern the specific (cultural) setting of the cases and the use of existing data.

Preliminary suggestions for fostering social well-being include change management, participatory design, being alert of the identified risks of activity-based offices and supporting privacy regulation, identity marking and a sense of community, as well as a diversity of informal face-to-face interactions balanced with quiet spaces.

This article contributes to the conceptualization of social well-being in contemporary offices by discussing established social well-being theory and analysing real-world data, using a method novel to management research.

The purpose of this paper is to suggest a formalism given by an equation suitable for simulating discrete systems with space-time variation in addition to other change variables. With such formalism, multidimensional dynamical models of discrete complex systems, such as the social systems and ecosystems, can be built.

This formalism is named as discrete multidimensional dynamic system (DMDS). The DMDS provides a way to consider the variation of the density of a state variable with regard to the variables of the change space as a function of multidimensional rates. Multidimensional rates describe this evolution as a consequence of the relation of each multidimensional-point with a given set of other points of the change space. This relation contains the accessibility domains (sets of space points with which each space point is related).

This equation is compared with both the reaction-diffusion equation written in its finite difference form and the cellular-automata model, demonstrating its compatibility with them and an increase in generality, widening the scope of application. The steps to construct models of systems with multidimensional variation based on the equation that defines the DMDS are specified and tested.

Through the DMDS and a well-stated methodology, an application case is provided in order to describe the multidimensional demographic dynamics of an urban system. In this case, the numerical evolution of the population density by districts and cohorts is determined by the DMDS based on some hypothesis about functions of population diffusion between the different districts of the system.

The scope of application of the space-time dynamic system (STDS), given by the authors in a previous work, has been extended to discrete and multidimensional systems. STDS model produces better results than the reaction-diffusion model in validation.

The freemium pricing model is dominant in digital products such as mobile applications. While limited evaluation of a product such as when a consumer is under time pressure, has been found to increase consumer preference for the free version (“the zero price effect”), this paper aims to explore moderators that attenuate or reverse that effect.

Three experiments test the role of anchoring effects induced by time pressure in moderating the zero price effect.

The studies offer evidence that anchoring effects induced by time pressure can be directed to reduce preference for free versions of products. In addition, these effects are mediated by the perceived performance risk of a product and an upper boundary condition for monetary price level is found.

This research demonstrates exceptions to time pressure’s role in intensifying the zero price effect. Future research could focus on additional moderators of the effect such as the need for certainty and examine time pressure’s effect on in-app purchases.

These findings can be directly applied by marketers of digital products using a freemium pricing model who wants to use time pressure to create urgency with customers without pushing them toward the free version of a product.

This paper finds exceptions to the zero price effect where consumers exhibit a stronger preference for the paid (vs free) version of a product when under time pressure.

About 13 to 44 per cent of motor faults are caused by bearing failures in induction motors (IMs), where lubrication plays a significant role in maintaining rotating equipment because it minimizes friction and prevents wear by separating parts that move next to each other, and more than 35 per cent of bearing failures can be attributed to improper lubrication. An excessive amount of grease causes the rollers or balls to slide along the race instead of turning, and the grease will actually churn. This churning action will eventually wear down the base oil of the grease and all that will be left to lubricate the bearing is a thickener system with little or no lubricating properties. The heat generated from the churning, insufficient lubricating oil will begin to harden the grease, and this will prevent any new grease added to the bearing from reaching the rolling elements, with the consequence of bearing failure and equipment downtime. Regarding the case of grease excess in bearings, this case has not been sufficiently studied. This work aims to present an effective methodology applied to the detection and automatic classification of mechanical bearing faults and bearing excessively lubricated conditions in an IM through the Margenau-Hill distribution (MHD) and artificial neural networks (ANNs), where the obtained results demonstrate the correct classification of the studied cases.

This work proposed an effective methodology applied to the detection and automatic classification of mechanical bearing faults and bearing excessively lubricated conditions in an IM through the MHD and ANNs.

In this paper, three cases of study for a bearing in an IM are studied, detected and classified correctly by combining some methods. The marginal frequency is obtained from the MHD, which in turn is achieved from the stator current signal, and a total of six features are estimated from the power spectrum, and these features are forwarded to the designed ANN with three output neurons, where each one represents a condition in the IM: healthy bearing, mechanical bearing fault and excessively lubricated bearing.

The proposed methodology can be applied to other applications; it could be useful to use a time–frequency representation through the MHD for obtaining the energy density distribution of the signal frequency components through time for analysis, evaluation and identification of faults or conditions in the IM for example; therefore, the proposed methodology has a generalized nature that allows its application for detecting other conditions or even multiple conditions under different working conditions by a proper calibration.

The lubrication plays a significant role in maintaining rotating equipment because it minimizes friction and prevents wear by separating parts that move next to each other, and more than 35 per cent of bearing failures can be attributed to improper lubrication and it negatively affects the efficiency of the motor, resulting in higher operating costs. Therefore, in this work, a new methodology is proposed for the detection and automatic classification of mechanical bearing faults and bearing excessively lubricated conditions in an IM through the MHD and ANNs. The proposed methodology uses a total of six features estimated from the power spectrum, and these features are sent to the designed ANN with three output neurons, where each one represents a condition in the IM: healthy bearing, mechanical bearing fault and excessively lubricated bearing. From the obtained results, it was demonstrated that the proposed approach achieves higher classification performance, compared to short-time Fourier transform, Gabor transform and Wigner-Ville distribution methods, allowing to identify mechanical bearing faults and bearing excessively lubricated conditions in an IM, with a remarkable 100 per cent effectiveness during classification for treated cases. Also, the proposed methodology has a generalized nature that allows its application for detecting other conditions or even multiple conditions under different working conditions by a proper calibration.

There are currently two issues that generate growing interest among specialized scholars within the family business field: technological innovation (TI) and socioemotional wealth (SEW). While it is true that both topics are highly popular among researchers, the joint study of both perspectives is scarce. Thus, the purpose of this paper is to analyse the interrelationships between TI and SEW in the context of family firms.

This literature review systematically analyses the findings of 25 journal articles focusing on TI and SEW, published between 2012 and 2018.

The findings reveal an integrative approach, identifying different variables that relate TI and SEW. A conceptual framework is built in which these variables are incorporated into four categories (SEW, TI, moderating effects and performance). New lines of research emerge with the development of a conceptual model and the formulation of six propositions.

The conceptual framework can be useful as integrative summary of the factors that family business managers and directors should take into account to be successful in implementing innovative projects and strategies.

The study of TI from the SEW approach has emerged as a fruitful field of research in recent years, but the current knowledge of the role that SEW plays in family firms’ TI is still scarce. This paper contributes to the family business literature by offering a conceptual framework of the SEW–TI relationship and new research avenues that will provide a better comprehension for scholars and specialists for future investigations in the field.

Actualmente existen dos temas que generan un creciente interés entre los académicos especializados en el campo de estudio de la empresa familiar: la innovación tecnológica y la riqueza socioemocional. Si bien es cierto que ambos temas son muy populares entre los investigadores, el estudio conjunto de ambas perspectivas es escaso. Así, el objetivo de este trabajo es analizar las interrelaciones entre la innovación tecnológica (IT) y la riqueza socioemocional (SEW) en el contexto de las empresas familiares.

Esta revisión de la literatura analiza sistemáticamente los hallazgos de 25 artículos de revistas que se centran en la IT y el SEW, publicados entre 2012 y 2018.

Los hallazgos revelan un enfoque integrador, identificando diferentes variables que relacionan la IT y el SEW. Así pues, se construye un marco conceptual en el que estas variables son incorporadas en cuatro categorías (SEW, IT, efectos moderadores y rendimiento). Nuevas líneas de investigación surgen con el desarrollo de un modelo conceptual y la formulación de seis proposiciones.

El marco conceptual puede ser útil como resumen exhaustivo de los factores que los gerentes y directores de empresas familiares deben tener en cuenta para tener éxito en la implementación de proyectos y estrategias innovadoras.

El estudio de la IT desde el enfoque del SEW ha surgido como un campo de investigación fructífero en los últimos años, pero el conocimiento actual del rol que juega el SEW en la IT de las empresas familiares es todavía escaso. Este trabajo contribuye a la literatura de la empresa familiar ofreciendo un marco conceptual de la relación SEW-IT y nuevas vías de investigación que proporcionarán una mejor comprensión a académicos y especialistas para futuras investigaciones en este campo de estudio.

Revisión general

Actualmente existem dois temas que geram um crescente interesse entre os acadêmicos especializados no campo de estudo da empresa familiar: inovação tecnológica e riqueza sócio-emocional. Conquanto é verdadeiro que ambos temas são muito populares entre os investigadores, o estudo conjunto de ambas perspectivas é escasso. Assim, o objectivo deste trabalho é analisar as inter-relações entre inovação tecnológica (IT) e riqueza socioemocional (SEW) no contexto das empresas familiares.

Esta revisão da literatura analisa sistematicamente os achados de 25 artigos de revistas que se centram na IT e o SEW, publicados entre 2012 e 2018.

Os achados revelam um enfoque integrador, identificando diferentes variáveis que relacionam a IT e o SEW. Constrói-se um marco conceptual no qual estas variáveis são incorporadas em quatro categorias (SEW, TI, efeitos moderadores e rendimento). Novas linhas de investigação surgem com o desenvolvimento de um modelo conceptual e a formulação de seis proposições.

O marco conceptual pode ser útil como resumo exhaustivo dos factores que os gerentes e diretores de empresas familiares devem ter em conta para ter sucesso na implementação de projectos e estratégias inovadoras.
