The purpose of this paper is to enhance the existing socioemotional wealth (SEW) theory. Particularly, the current research proposes a dynamic SEW model using insights from prospect theory. The application of the proposed dynamic SEW model leads to several propositions that will reveal the relationship amongst family business, transgenerational succession, business risks and diversification strategy.

This study is mainly a theoretical research. A dynamic SEW model is proposed in which the SEW is not static and can be increasing or decreasing. SEW is framed as a gain or loss under different scenarios, and the shift in reference point will change the framing or value of SEW.

The current research presents several interesting propositions based on the dynamic SEW model. Generally, family firms are less likely to diversify than non-family firms. However, when family firms face business risks, they are more likely to diversify than those that do not face business risks. Family firms with second generation involvement in management are more likely to diversify than those without second generation involvement. The dynamic SEW model can also be applied to analyse R&D and IPO underpricing for family firms.

This study builds a dynamic SEW model, which is totally new to the literature. The conceptual framework that reveals the relationships amongst family business, transgenerational succession, business risks and diversification strategy also contributes to the literature and has empirical implications to researchers, policy makers and family business owners.

This study explores whether herd behavior exists for equity crowdfunding investors in China and whether this herding is rational.

Based on signaling theory and social learning theory, two hypotheses were proposed. This study employed two approaches to collect data. First, this paper analyzed 3,041 investments on an equity crowdfunding platform in China using Python programming and built a panel data model. Second, based on a unique experiment design, this study conducted several relevant herd behavior simulation experiments.

We found that investors in the Chinese equity crowdfunding market exhibit herd behavior and that this herding is rational. Project attributes play a negative role in moderating the relationship between the current investment amount and cumulative investments. Experimental results further support our findings.

This study contributes to the emerging literature on herding in crowdfunding by focusing on equity crowdfunding in China. We are the first to explore whether Chinese equity crowdfunding investors exhibit rational herding behavior. The study is also original in applying social learning theory to equity crowdfunding and in using both actual crowdfunding campaigns and experimental approaches to collect data. This study has valuable implications to practice.

The transformation towards the Green Economy (GE) in Poland is a relatively new topic for researchers, policymakers and business practitioners. A comprehensive picture of the shift towards the GE can help mentioned groups translate theoretical assumptions into practice.

This chapter presents the assessment of Poland's shift towards the GE, measured by the proposed Green Transformation Index (GTI).

The set of GE indicators was elaborated in Structured Literature Review (SLR) variation method. Then, this set of indicators was compared with the Statistics Poland (GUS) secondary data and employed in the taxonometric calculation methods.

In the result, the GTI for the Polish economy was proposed and calculated between 2007 and 2020. The GTI allowed us to present a dynamic analysis of the transformation towards GE in Poland.

The importance of Carbon dioxide (CO₂) gas detection as a greenhouse and exhale breathe gas is an undeniable issue. This study aims to propose a new miniaturized, low cost and portable no dispersive infrared (NDIR) system for detecting CO₂ gas.

Poly(methyl methacrylate) (PMMA)-based channels with Au coating because of its high reflection properties in IR region were used in this work. The optical windows were fabricated using PDMS polymer which is cost effective and novel in comparison to other conventional methods. The effects of channel dimensions, lengths and entrance angle of light on optical path length and losses were analyzed with four types of channel using both simulation and experimental tests.

The simulation results indicate that the 0 degree light entrance angle is the most efficient angle among different investigated conditions. The experimental data are in agreement with the simulation results regarding the loss and optical path length in different types of channel. The experimental tests were performed for the 0.5% up to 20% of CO₂ concentration under constant temperature and humidity condition. The results show that the device with 5  and 2 cm channels length were saturated in 4% and 8% concentration of CO₂ gas, respectively. Response and recovery times were depending on gas concentration and channels specifications that in average found to be 10 S and 14 S, respectively, for the largest size channel. Moreover, the environment humidity effect on detection system performance was investigated which had no considerable influence. Also, the saturation fraction absorbance value for devices with various dimensions were 0.62 and 0.8, respectively.

According to the performed curve fitting for practical situation and selected CO₂ concentration range for experimental tests, the device is useful for medical and environmental applications.

PMMA with Au deposition layer was used as a basic material for this NDIR system. Besides, a novel PDMS optical window helps to have a low cost device. The effects of channel dimensions, lengths and entrance angle of light on optical path length and losses were analyzed using both simulation and experimental tests. Using narrowband optical filter (100 nm bandwidth) helps to have a system with good CO₂ selectivity. In addition, experimental tests with different channel dimensions and lengths covered a considerable range of CO₂ concentration useful for medical and environmental applications. Finally, curve fitting was adopted for a modified Beer–Lambert law as a practical situation.

Workforce diversity is widely believed to enhance the knowledge and perspectives of organizations. The purpose of this study is to synthesize the existing diverse literature on workforce diversity and to enlighten the avenues for future research in managing workforce diversity.

This study performs a comprehensive review of empirical and conceptual studies published on workforce diversity and its outcomes in the top 13 peer-reviewed leading management journals between 1990 and 2019.

The assessment of diversity literature reported mixed and inconsistent results that are the critical challenges of diversity management. Furthermore, most studies have not individually identified the problems of diversity dimensions. To understand the problems, this study has divided the different dimensions of diversity (e.g. age, gender, race, education, functional background and tenure) and their results, supported by various theories. The findings of this study suggested a different reason for existing conflicts and proposed a future research agenda.

To overcome the challenges of diversity, this study has proposed the future research agenda for future research. to take optimum advantage of workforce diversity, this study contributes a theoretical perspective that enhances the understanding of existing diversity in organizations and develops diverse organizations.

Although family business literature acknowledges that family firms owners are motivated by a set of socioemotional wealth (SEW) goals along with firm-centric business goals, yet a consistently predictable pattern of relationship between SEW and financial wealth is yet to be discerned. The purpose of this paper is to propose a theoretical model based on the stakeholder approach to suggest that family commitment mediates the association between the dimensions of SEW and firm performance.

A set of hypotheses are proposed that are tested using structural equation modeling with data collected from 357 medium to large sized privately held family firms in Bangladesh. The data analysis is done with SmartPLS (v.3.2).

The results indicate that family commitment partially mediates the relationships between family control and influence, family identification, emotional attachment and renewal of family bonds through dynastic succession and firm performance. The only non-significant relationship was between binding social ties and firm performance. The results provide a more nuanced understanding of the link between SEW goals and firm performance, and present important implications for theory and practice.

The cross-sectional nature of the study exposes it to the specter of common method bias despite the fact that procedural remedies were initiated to minimize the impact of such occurrence. A longitudinal study with data obtained from multiple individuals at different levels of the organization would possibly yield more robust findings. Furthermore, in the absence of a multi-country and multi-sector analysis, a broad generalization of the findings may not be feasible.

The knowledge that family identity, emotional attachment and renewal of family bonds through dynastic succession may be leveraged to enhance the commitment of subsequent generation of family firm owners to the firm that may be pertinent to incumbents who desire to see their successors more engaged in the family enterprise. Furthermore, knowing that excessive focus on family control over the firm leads to negative outcomes is also pertinent to family firm leaders.

Survival of family businesses is vital to the global economy as one of the primary drivers of global GDP growth and source of new employment. Policy makers can benefit from the findings of this study to customize policies that take into cognizance the importance of SEW owners of family firms and the fact that some of these SEW goals actually benefit the firm in terms of enhanced commitment to the enterprise and consequently superior firm performance.

The role of family commitment as a mediator between SEW and firm performance has not been dominant in the literature. By providing a finer-grained understanding of how family commitment accounts for the relationship between family-centric non-economic goals such as SEW and firm-centric goals such as business performance, the study presents a theoretical link between sociomemotional wealth and financial wealth in the context of private family firms.

The purpose of this paper is to solve the common problems of outer phenomenon and stress concentration among pneumatic networks soft actuators.

On the basis of imitating the caterpillar structure, the new soft actuator adopts the integral circular ladder structure instead of the traditional independent distributed structure as the air chamber. Through the comparison of several different structures, the parabolic in-wall curve is found to be fit for designing the optimal integrated chamber structure of the soft actuator. The curve function of each ladder chamber is computed based on the torque distribution model, aiming to decrease the terminal deformation. Meanwhile, the FEM analysis method is applied to establish the motion model of the integrated parabolic ladder soft actuator. The model’s accuracy, as well as structure’s deformation and stress, are verified.

Compared with the FEM data, the experimental data indicate that the new soft actuator has no obvious outer phenomenon, the maximum stress decreases and the stiffness increases. The new actuator is applied for designing a flexible gripper to grasp objects of different shapes and sizes. The gripper can grasp objects of 52.6 times its own mass.

The designed gripper is available for flexible production in various fields, such as capturing fruits of different sizes, soft foods or parts with complex shapes.

This paper proposes a new type soft actuator, which provides a solution for exploring the field of the soft robot. The problems of outer phenomenon and stress concentration are suppressed with pneumatic networks soft actuators.

Soft robotics, regarded as a new research branch of robotics, has generated increasing interests in this decade and has demonstrated its outperformance in addressing safety issues when cooperating with human beings. However, there is still lack of accurate close-loop control because of the difficulty in acquiring feedback information and accurately modeling the system, especially in interactive environments. To this end, this paper aims to improve the controllability of the soft robot working in specific underwater environment. The system dynamics, which takes complicated hydrodynamics into account, is solved using Kane’s method. The dynamics-based adaptive visual servoing controller is proposed to realize accurate sensorimotor control.

This paper presents an image-based visual servoing control scheme for a cable-driven soft robot with a fixed camera observing the motions. The intrinsic and extrinsic parameters of the camera can be adapted online so that tedious camera calibration work can be eliminated. It is acknowledged that kinematics-based control can be only applied into tasks in the free space and has limitation in accelerating the motion speed of robot arms. That is, one must consider the unneglectable interaction effects generated from the environment and objectives when operating soft robots in such interactive control tasks. To extend the application of soft robots into underwater environment, the study models system dynamics considering complicated hydrodynamic effects. With the pre-knowledge of the external effects, the performance of the robot can be further improved by adding the compensation term into the controller.

The proposed controller has theoretically proved its convergence of image error, adaptive estimation error and the stability of the dynamical system based on Lyapunov’s analysis. The authors also validate the performance of the controller in positioning control task in an underwater environment. The controller shows its capacity of rapid convergence to and accurate tracking performance of a static image target in a physical experiment.

To the best of the authors’ knowledge, there is no such research before that has developed dynamics-based visual servoing controller which takes into account the environment interactions. This work can thus improve the control accuracy and enhance the applicability of soft robotics when operating in complicated environments.

In Malaysia, there are a few numbers of frameworks and checklists in order to evaluate the sustainable performance of buildings. In addition, most of these assessment frameworks or checklists focus on environmental sustainability disregarding social and economic pillars. The research in social and economic sustainability in the construction industry is pushing forward, albeit at a slow pace. In addition, the growing number of sustainable criteria in the literature highlights the importance of a systematic framework for construction initiatives. This research aims to propose a comprehensive framework based on three pillars of sustainability, and, additionally, to categorize them in a manner that is applicable for all relevant stakeholders based on their level of involvement and needs. Finally, it identifies the relation between each criterion and stage of the construction lifecycle with the assistance of an expert panel. This research produces a framework that is useful for Malaysian construction stakeholders to reinforce their approach towards sustainability through social and economic aspects that are currently underestimated in the construction industry.

Drawing on threatened egoism theory, tournament theory and the extended agency model of narcissism, this paper aims to compare the effects of two different forms of grandiose narcissism of employees, namely, narcissistic rivalry (NR) and narcissistic admiration (NA), on knowledge hiding (HIDE), and investigate the potential mediating mechanism and boundary conditions.

Based on a three-wave survey of 296 participants recruited from six high-tech enterprises in China, the paper tests the proposed model by performing partial least squares structural equation modeling and a bias-corrected bootstrapping procedure.

The results indicate that NR facilitates knowledge hiding, while NA inhibits employees’ knowledge-hiding behavior. Emotional exhaustion plays a significant mediating role between NR and HIDE, and interpersonal trust negatively mediates the relationship between NA and HIDE. Moreover, interactional justice perception not only weakens the positive correlation between NR and emotional exhaustion but also weakens the indirect influence of NR on HIDE via emotional exhaustion. On the contrary, interactional justice perception strengthens the impact of NA on interpersonal trust, thus enhancing the mediating effect of NA on HIDE.

The present study expands the literature on knowledge management by addressing the underlying paradoxes of grandiose narcissistic employees’ HIDE behavior based on different connotations of narcissism and revealing the intervening mechanism with interactive justice perception as the moderator.
