Abstract
Purpose
The purpose of this paper is to overcome evaluative limitations of previous studies to provide a more decisive test of the causal relationships implied in the Baldrige Criteria for Performance Excellence (CPE) using a unique data source.
Design/methodology/approach
The authors employ partial least squares path modeling on blinded scoring data from Baldrige Award applicants. In addition, the authors conduct multi-group analysis to examine whether the hypothesized causal model is universal across different industry sectors.
Findings
The path analysis provided strong support for the CPE framework in its entirety. However, analysis of sector-specific subsets of the data did not confirm all relationships, suggesting the possibility of industry-dependent performance excellence frameworks and raising new research questions to be explored.
Practical implications
This research offers several pertinent implications for managers who seek to translate the theoretical CPE framework to actionable quality-improvement efforts.
Originality/value
CPE operationalizes many total quality management (TQM) concepts and provides guidelines to TQM programs. This study validates the CPE framework using the most relevant data set to date – the applicant scoring data. The authors are also the first to investigate the cross-industry differences in the relationships between the CPE constructs.

Abstract
Purpose
This chapter reconsiders commonly held views on the ownership and management of private property, contrasting capitalist and simple property, particularly in relation to how a firm shareholder governance model has shaped society. This consideration is motivated by the scale and scope of the modern global crisis, which has combined financial, economic, social and cultural dimensions to produce world disenchantment.
Methodology/approach
By contrasting an exchange value standpoint with a use value perspective, this chapter explicates current conditions in which neither the state nor the market prevail in organising economic activity (i.e. cooperative forms of governance and community-created brand value).
Findings
This chapter offers recommendations related to formalised conditions for collective action and definitions of common guiding principles that can facilitate new expressions of the principles of coordination. Such behaviours can support the development of common resources, which then should lead to a re-appropriation of the world.
Practical implications
It is necessary to think of enterprises outside a company or firm context when reflecting on the end purpose and means of collective, citizen action. From a methodological standpoint, current approaches or studies that view an enterprise as an organisation, without differentiating it from a company, create a deadlock in relation to entrepreneurial collective action. The absence of a legal definition of enterprise reduces understanding and evaluations of its performance to simply the performance by a company. The implicit shift thus facilitates the assimilation of one with the other, in a funnel effect that reduces collective projects to the sole projects of capital providers.
Originality/value
Because forsaking society as it stands is a radical response, this historical moment makes it necessary to revisit the ideals on which modern societies build, including the philosophy of freedom for all. This utopian concept has produced an ideology that is limited by capitalist notions of private property.

Abstract
Purpose
This research aims to investigate the trajectory tracking problem for a four-wheel independent drive autonomous vehicle (4WID) and propose an integrated, coordinated control strategy to address the mutual interference between trajectory tracking and stability control in extreme cases.
Design/methodology/approach
The authors establish an adaptive preview model that modifies the preview distance based on vehicle speed. They utilize a three-degrees-of-freedom vehicle model and employ model predictive control to calculate the necessary front wheel angle for trajectory tracking. In terms of longitudinal control, a longitudinal coordinated control mechanism is established to achieve the two conflicting objectives of trajectory tracking accuracy and dynamic stability through early deceleration. A stability controller based on sliding mode control (SMC) is designed, considering tire constraints and tracking the optimal yaw angle and sideslip angle. Furthermore, a lateral coordinated control strategy is developed, considering the weight coefficient of stability control, and the yaw moment is calculated and distributed based on the vehicle torque requirements.
Findings
The proposed integrated, coordinated control strategy successfully addresses the mutual interference between trajectory tracking and stability control in extreme cases for the 4WID vehicle. The strategy achieves trajectory tracking accuracy, dynamic stability and reduced energy consumption while taking into account tire constraints.
Originality/value
We have proposed a cooperative control strategy for the trajectory tracking problem of autonomous driving vehicles. This strategy is different from previous methods in that we have taken into account the integrated dynamic control in both longitudinal and lateral directions, balancing the conflicting control requirements and reducing energy consumption, improving trajectory tracking accuracy and vehicle dynamic stability. We have verified the feasibility of this strategy through joint simulation under different driving conditions.

Abstract
Governments around the world instituted guidelines for calculating energy efficiency of vehicles not only by models, but by the whole universe of new vehicles registered. This paper compiles Multi-criteria decision-making (MCDM) studies related to automotive industry. We applied a Systematic Literature Review on MCDM studies published until 2015 to identify patterns on MCDM applications to design vehicles more fuel efficient in order to achieve full compliance with energy efficiency guidelines (e.g., Inovar-Auto). From 339 papers, 45 papers have been identified as describing some MCDM technique and correlation to automotive industry. We classified the most common MCDM technique and application in the automotive industry. Integrated approaches were more usual than individual ones. Application of fuzzy methods to tackle uncertainties in the data was also observed. Despite the maturity in the use of MCDM in several areas of knowledge, and intensive use in the automotive industry, none of them are directly linked to car design for energy efficiency. Analytic Hierarchy Process was identified as the common technique applied in the automotive industry.

Abstract
Purpose
Existing models of product assembly scheme design often ignore the constraint relations among design thinking. In order to grasp the functions of each part and the constraint relations among them in product assembly system macroscopically, further design and variation of product assembly system should be made according to design thinking. This paper seeks to address these issues.
Design/methodology/approach
Through analyzing the similarity between biological organization system and product system and taking biology knowledge for reference, product assembly system was expressed as product function gene, product constraint gene, product function protein, product constraint protein and product cell and so on in this paper. The product gene model composed of product function gene groups and constraint genes was established and a modeling method based on it was proposed.
Findings
The author applied this method to model the 5‐DOF manipulator of complex diamond manufacturing special equipment with good results which proved the effectiveness of this modeling method.
Originality/value
By identifying constraint relations and design thinking in the gene model, the system makes the modification process which is conducted by the designers automatically identified and varied to achieve computer‐aided design and assembly.

This study attempts to examine the relationship between board characteristics and dividend payout decisions of conventional and Islamic banks.
Abstract
Purpose
This study attempts to examine the relationship between board characteristics and dividend payout decisions of conventional and Islamic banks.
Design/methodology/approach
This study employed unbalanced panel data of both Indonesian conventional and Islamic banks over the period 2008–2021, estimated using tobit and logit models. Dividend payout decisions were measured using the dividend payout ratio and probability to pay dividends. Meanwhile, board characteristics were represented by board size, board independence, board gender diversity, board meeting, board chairman tenure and board chairman tenure.
Findings
The results show that, in the context of conventional banks, board meetings, board chairman tenure and board chairman tenure are correlated with higher dividend payout decisions, while board gender diversity indicates lower dividend payout decisions. On the other hand, in the context of Islamic banks, board size and board meetings are associated with higher dividend payout decisions, while board independence and board chairman tenure are related to lower dividend payout decisions.
Research limitations/implications
This study fills the gaps in the literature on bank dividend policy. It also provides additional insights regarding the relationship between board characteristics and dividend payout decisions in the context of conventional and Islamic banks. In addition, this study gives essential contributions to regulators and investors of both banks, especially in a developing country, Indonesia.
Originality/value
This study is one of the first to provide empirical results regarding the relationship between board characteristics and dividend payout decisions of conventional and Islamic banks. Board characteristics are indicated as one of the fundamental factors that determine dividend payout decisions of both conventional and Islamic banks in Indonesia.

Abstract
Purpose
The purpose of this paper is to introduce the analysis and performance of a hybrid multiple access scheme which combines interleave division multiple access (IDMA) and code division multiple access (CDMA), referred to as IDMA/CDMA. With experimentations, the scheme can achieve good performance with simple user ends for the system.
Design/methodology/approach
IDMA technique is employed as the uplink transmission and CDMA technique as the downlink transmission. The performance comparison of IDMA and IDMA/CDMA downlink is studied with Monte Carlo simulations to investigate the bit error rates. For IDMA/CDMA downlink, the signals are interleaved by random interleavers, spreaded by M‐sequence and orthogonal Gold sequence, respectively, and then transmitted over an AWGN with BPSK modulation. Moreover, a channel estimation approach for IDMA based on expectation maximization (EM) algorithm is also presented.
Findings
The multi‐user detection (MUD) algorithm in uplink IDMA systems is much simpler than that used in traditional CDMA systems. It is also well known that the orthogonal spreading codes in CDMA can effectively help suppress the MAI in the synchronized environments. But for the asynchronized application, the performance of CDMA systems will degrade due to the serious multiple user interference. According to traditional IDMA and orthogonal code division multiple access/IDMA signal detection algorithms, every UE has to detect all of the signals of other users for iterative detection. The advantages of IDMA and CDMA technologies can be utilized substantially.
Originality/value
The proposed hybrid multiple access scheme can achieve a very simple chip‐by‐chip iterative MUD strategy at base station, and the simplified receiving operation at UE. On the other hand, this paper also evaluates channel estimation approach for IDMA based on EM algorithm.

Abstract
Purpose
The transition from fossil fuel-based energy systems to renewable energy sources, commonly referred to as the energy transition, is essential for combating climate change. However, comprehensive studies that thoroughly examine the financial mechanisms involved in this process are lacking. Despite the availability of various financial tools, there is a notable absence of extensive research that synthesizes and categorizes these mechanisms into broad groups.
Design/methodology/approach
A systematic literature review is used to explore a comprehensive framework for financial mechanisms related to the energy transition and their application across six stages of the process.
Findings
The framework of financial mechanisms for energy transition encompasses these six factors: public financing mechanisms, private financing mechanisms, market-based mechanisms, innovative financing mechanisms, risk mitigation instruments and institutional support and capacity building.
Originality/value
This is the first study that thoroughly reviewed the financial mechanisms involved in the energy transition process.

Abstract
Purpose
Many developing countries have encountered frequent pollution accidents during their rapid development, while the previously weak environmental insurance systems could seriously undermine the progress of sustainable development. Some developing countries like China has initiated and strengthened environmental pollution liability insurance, so how effective this system would be in resolving enterprises environmental risks need to be further revealed.
Design/methodology/approach
This research identifies the possible consequence that compulsory environmental pollution liability insurance pilot (CEPLIP) policy would bring to the risk-taking capacity of heavy-polluting corporations of China by the Differences-in-Differences (DID) approach.
Findings
The result supports the implementation of CEPLIP policy in increasing corporate risk-taking capacity. Furthermore, the CEPLIP policy can promote the corporate’s risk-taking capacity by reducing financial distress constraints and enhancing trade credit, supporting its dual role of “fallback effect” as well as “external supervision effect” of environmental insurance. As a result of heterogeneity test, the policy is more pronounced in enterprise samples with mature life cycle stage or lower industrial concentration degree. Similarly, it is more significant in enterprise samples owned better environmental management capabilities or greater strategic deviance.
Originality/value
This paper verifies the effectiveness of the CEPLIP policy by strengthening its supervision mechanism and restraining opportunistic behavior tendency and provides implications for alleviating increasing environmental risk pressure and building more sustainable environmental protection management systems.
