Abstract
Purpose
Fixed mode noise and random mode noise always exist in the image sensor, which affects the imaging quality of the image sensor. The charge diffusion and color mixing between pixels in the photoelectric conversion process belong to fixed mode noise. This study aims to improve the image sensor imaging quality by processing the fixed mode noise.
Design/methodology/approach
Through an iterative training of an ergoable long- and short-term memory recurrent neural network model, the authors obtain a neural network model able to compensate for image noise crosstalk. To overcome the lack of differences in the same color pixels on each template of the image sensor under flat-field light, the data before and after compensation were used as a new data set to further train the neural network iteratively.
Findings
The comparison of the images compensated by the two sets of neural network models shows that the gray value distribution is more concentrated and uniform. The middle and high frequency components in the spatial spectrum are all increased, indicating that the compensated image edges change faster and are more detailed (Hinton and Salakhutdinov, 2006; LeCun et al., 1998; Mohanty et al., 2016; Zang et al., 2023).
Originality/value
In this paper, the authors use the iterative learning color image pixel crosstalk compensation method to effectively alleviate the incomplete color mixing problem caused by the insufficient filter rate and the electric crosstalk problem caused by the lateral diffusion of the optical charge caused by the adjacent pixel potential trap.

Abstract
Purpose
This paper aims to provide a review of the challenges facing the reform of SOEs, and to address the impacts of SOE reform on business executives, on the base of literature review and empirical data collected in Guangzhou, China.
Design/methodology/approach
A qualitative research on the base of literature review, supported by empirical data collected from surveys, interviews, and focus group discussion.
Findings
Although China has made significant achievement in economic reform and the transition into a market system and civil society since 1978, there are still fundamental challenges associated with the reform of state owned enterprises (SOEs). It seems that privatisation will not necessarily solve the complex problems associated with SOEs. This paper suggests that a balanced approach reflecting the best of SOE provision and triple bottom line management appears to provide the best way forward for continuing prosperity in China. The current direction of SOE reform seems to have been driven by privatisation and economic rationalism, rather than a more balanced economic and social strategy. If this trend continues, the challenges for business executives, and the general society, can be overwhelming, and not lead to a more sustainable economy, let alone society, in the medium to long term.
Originality/value
Reform of SOEs has impacted on China fundamentally. Against the common view that business managers are the social group that is benefiting from SOE reform, this paper focuses on factors affecting the economic and social status of business executives, especially the challenges associated with the reform of SOEs. Supported by primary and secondary data sources, it draws attention to the situation that although the economic and social status of business executives continues to rise in China, insecurity and stress on business executives are growing. Reforms associated with changing SOEs are viewed as possible sources of challenges facing the Chinese economy and business life. Current SOE reform seems to have focused on the economic bottom line. A more balanced approach in the reform of SOEs is suggested for a more sustainable economy and society.

Abstract
Purpose
This study aims to examine how embeddedness influences consultants' information seeking when making decisions within a social network of relationships, and how these social networks evolve throughout the project delivery stages. The study is grounded in social network theory and examines embeddedness from three perspectives: structural (network cohesion), relational (tie strength in terms of friendship and knowledge awareness) and actor prominence.
Design/methodology/approach
A social network analysis (SNA) questionnaire was administered to a team of consultants working on a management consultancy project in Shanghai, China. The SNA measures of density, degree centrality and betweenness centrality were used to analyse relationship patterns among project team members, permitting comparison between the networks. Networks were also compared across the three project delivery stages of collect, consider and create.
Findings
Structural embeddedness was observed in the active information seeking behaviour among consultancy team members. The moderate network density of the self-organising information seeking networks across the project delivery stages ensures that the team remains connected but avoids information redundancy and overload. Relational embeddedness was evident through the multiplexity of ties among team members with overlapping friendship and information seeking relationships. The knowledge awareness network's sparseness indicates a team of autonomous knowledge workers with distributed expertise. Project managers were the most prominent actors across the three project delivery stages, underlining these actors' relational leadership role.
Practical implications
The study provides a deeper understanding of collaborative decision-making behaviours in dynamic-project environments. Limited attempts have been made to visualise and analyse the relationships involved in small consulting teams. The novelty of the network approach adopted stems from its ability to offer a structural view of the relationship among consultants, thus offering a distinctive and arguably more complete picture of consultancy team dynamics.
Originality/value
The study validates the social network theory of embeddedness in a real-world collaborative decision-making setting and provides a deeper understanding of information seeking behaviours for decision-making in dynamic-project environments. From a project management process viewpoint, the evolving nature of the information seeking network as it changes across the project stages with associated actors' roles was also visualised graphically, offering a distinctive and arguably more complete picture of consultancy team dynamics.

Abstract
Purpose
The contribution of project success and the organisation's efficiency is consensual in the literature. However, the value of project management (PM) brings to the organisation's effectiveness through the alignment with strategy, contributing to its competitiveness and business success, is yet little explored. This study addresses the literature gap that concerns the relationship between PM and the organisation's competitiveness, proposing a holistic conceptual model to understand of how PM brings value to the organisation. This work also aims to demonstrate the practical implications of theoretical contributions to the value of PM. For this, a detailed action research (AR) was planned to show how researchers and practitioners could work and collaborate in a real problem and prove the AR approach's adequacy to the PM field.
Design/methodology/approach
The methodology starts with a systematic literature review (SLR), followed by content analysis to develop a conceptual model of PM's value. To validate the theoretical constructs and transfer the results to real context, an AR plan is then carried out to support a specific PM problem presented by an automotive industry company.
Findings
The results have theoretical and practical implications. An original conceptual model is developed–the value of PM: Key factors–defending a multidimensional and holistic perspective to understand the PM's value. A set of key factors was identified, structured, interrelated and exemplified their practical implementation in a single company. In addition to the technical key factors identified in the literature review, the AR plan unveils crucial social aspects to improve PM's value, such as leadership, strong communication and open processes. This work shows the central role of PM methodologies in integrating and interconnecting the key factors, emphasizing the projects' strategic level.
Research limitations/implications
The present work was developed in a specific and particular organisational context and industry.
Practical implications
The AR plan presents a company's original programme–Hyper Competitiveness (HC) Temple–implemented in an automotive company. Project management professionals could understand how this company implemented each key factor, defended in a conceptual model and lead the project's results to the business value.
Originality/value
The research originality lies in rethinking PM's value to organisations from a holistic perspective: multi-dimensional, temporal, life cycle, multi-organisational, pointing out a set of technical and social key factors.

Abstract
Purpose
In today's digital and post-pandemic era, construction teams can span their boundary to obtain important resources and support in computer-mediated ways. However, the benefits of computer-mediated team boundary spanning (TBS) are mostly assumed. Empirical evidence for these benefits is in lack. Thus, this study attempts to investigate the influence of computer-mediated (instant messaging in this study) TBS on construction project performance and the underlying mechanism.
Design/methodology/approach
From the multiteam system (MTS) perspective, this study employs the input-process-outcome (IPO) framework and coordination theory to explore the influence of instant messaging-based team boundary spanning (IMTBS) on construction project coordination processes and project performance. A theoretical model is built and validated with a survey involving 206 construction projects.
Findings
Results show that IMTBS positively affects knowledge integration and project coordination, but negatively affects project commitment. The positive link between IMTBS and project performance is attributable to knowledge integration and project coordination. Further, project commitment is also found to negatively mediate the relationship between IMTBS and construction project performance.
Originality/value
To the best of the authors’ knowledge, this study is the first to empirically investigate the influence of TBS on construction project performance. As such, this study contributes to the literature on TBS in the construction field. In addition, the findings of this study unveil the double-edged characteristic of IMTBS, which should attract managers' attention. This also indicates that the form of TBS is a significant determinant of its effectiveness, which should attract scholars' attention in the future.

Abstract
Purpose
Although project management (PM) continues to rise in popularity, there is still a significant PM talent deficit, leading to more challenged or failing projects. To lower the PM talent deficit and mitigate the higher project failure rates, academic institutions have been developing PM curriculums aimed at inculcating a repertoire of competencies to the potential project managers. In developing an ideal well-rounded PM curriculum, academic institutions occasionally engage the input of industry partners and governing entities. The study aims to (1) compare the competencies in one of the leading industry competency model and framework (PMI Talent Triangle) to the competencies in the PM course syllabi learning outcomes, (2) determine the extent to which these two sets of PM competencies are aligned and (3) and explore avenues for improvements.
Design/methodology/approach
The study uses a purposeful sampling method to gather PM course syllabi. The PM competencies data are gleaned from the syllabi using the content analysis method. Thereafter, QSR NVivo qualitative statistical software is used to summarize and analyze the competency data from the learning outcomes.
Findings
The results reveal that most of the PM competencies in the course syllabi fall under the technical PM domain. Specifically, the top three competency elements in each domain are technical PM domain (PM skills, tools and techniques, schedule management and cost estimation/budget), leadership domain (team-building, verbal/written communication and problem-solving) and strategic and business management domain (strategic planning, analysis and alignment, benefits management and realization, customer relationship and satisfaction).
Research limitations/implications
The study investigates the alignment of the PM course competencies with competency domains in the PMI Talent Triangle, a global competence model that is well aligned with other global competence models such as the APM Competence Framework, the ICB4 Individual Competence Baseline and the PROMA3.
Practical implications
The results from this study provide guidelines useful in informing PM curricula re/design, as well as the inculcation of knowledge, skills, tools, techniques and behaviors needed for effective PM.
Social implications
The PM curriculum can be improved by partnering with PM industry leaders who can serve as advisors to the academy on industry needs, direction and emerging innovations that can inform PM learning outcomes, PM curricular design and the development of quality PM talent. The academy and the industry are encouraged to actively strive for mutual partnerships where PM professionals and academicians serve on each other's advisory boards. Also, the academy can partner with the industry professionals by developing curriculum resources such as case studies that bring the real-life PM applications to the classroom.
Originality/value
This study is motivated by the call for research studies that provide a holistic picture of the desired PM competencies and an exploration and definition of the educational needs in the PM curriculum.

Abstract
Purpose
This study investigates whether corporate sustainability capability (CSC) along with project management maturity (PMM) based capability contribute to perceived organizational success. It also studies how this contribution varies by project type employed in the organization.
Design/methodology/approach
The research is based on survey data collected from 66 managers of mostly small service businesses. The survey instrument consisted of a four-part questionnaire with 41 indicators focusing on CSC, maturity in project management knowledge areas and perceived internal and external organizational success. The SEM methodology, GLM (General Linear Model), and ANOVA are used for the analysis of the causal relationship among the indicators. The moderating effect of Project Type is analyzed using the Multi Group Analysis.
Findings
The findings demonstrate the impact of the successful integration of corporate sustainability and organizational PMM efforts on organizational success. Project management capability strengthens the effects of sustainability efforts, specifically in economic and social sustainability. Moreover, project type ranging from derivative to breakthrough moderates this effect.
Research limitations/implications
The findings demonstrate the strategic importance of corporate sustainability and its integration with organizational project management, valuing project sustainability management.
Practical implications
The study shows the importance of project management and sustainability capabilities for organizations in managing projects and developing vision, policy, and guidance with stakeholders, leading to organizational success.
Originality/value
This study reveals most success is achieved by maturity in stakeholder management, time, quality, communication and human resource management areas, economic and social sustainability capabilities demonstrated by platform and breakthrough projects.

Abstract
Purpose
Software process tailoring (SPT) plays a critical role in contemporary software development. Because SPT determines how a software project proceeds, its effectiveness should be investigated. Specifically, SPT is a collaborative yet highly conflictual process, and the existing literature has paid little or no attention to how team members coordinate and to how power distance (PD) influences coordination under this conflictual situation for the purpose of fostering SPT effectiveness.
Design/methodology/approach
A propositional research method is utilized by reviewing the extant literature regarding SPT, team coordination and PD. Accordingly, several propositions are developed to theorize the contributive and moderating effects of team coordinative capabilities and PD on SPT effectiveness.
Findings
This study advances the understanding of the underlying mechanisms of the four distinct coordination capabilities in performing SPT, which will help software firms comprehend the moderating effects of PD on the relationships among coordinative capabilities and SPT effectiveness.
Originality/value
This study extends coordination theory and reveals four coordination capabilities that nurture SPT effectiveness. Moreover, this study demonstrates how power plays a role in the coordination of a team through the collaborative yet divergent SPT decision process to yield an integrative tailoring solution. In particular, we take a fresh viewpoint of PD considering the member-member relationship in exploring its moderating effects in the SPT context.

This article explores how the social media usage affect team creative performance via transactive memory system, knowledge interaction and expertise coordination.
Abstract
Purpose
This article explores how the social media usage affect team creative performance via transactive memory system, knowledge interaction and expertise coordination.
Design/methodology/approach
The study is based on the perspective of transaction memory system and expertise coordination theory. A research model was constructed and tested, involving 289 individuals from 67 distributed agile software development teams.
Findings
The results indicate that social media usage is positively correlated with transactive memory system, and social media usage and transactive memory system have positive relations to knowledge interaction and expertise coordination. Moreover, this analysis shows that knowledge interaction has a positive relationship with expertise coordination, and expertise coordination positively affects team creative performance. However, knowledge interaction has no direct relationship on team creative performance, and its indirect impact on team creative performance was fully mediated by expertise coordination. This research shows that social media usage by distributed agile software development teams can support the development of transactive memory system and promote expertise coordination. In addition, knowledge interaction alone is not enough, and expertise coordination must be achieved to increase team creative performance.
Originality/value
First, this paper explores the mechanism of transactive memory system in distributed Agile Software Development teams from the perspective of social media, which is different from the previous information processing theory framework that confined transactive memory system to the cognitive aspects of knowledge coding, storage and retrieval. Second, this research focuses on the knowledge interaction and expertise coordination formed by team members in the process of communication in the context of social media usage, which confirms the crucial roles of social media usage and transactive memory system in team knowledge management and team creative performance. Then, this research also shows that the development of transactive memory system in the team is indeed an important factor to promote knowledge interaction and professional expertise coordination.

Abstract
Purpose
This study aims to explore the degree of Chinese consumers' trust and confidence in the Chinese dairy products supply chain and the relationships between trust and overall confidence in dairy products safety and quality.
Design/methodology/approach
This study collected data from 1,278 respondents by field survey from five provinces of China. The data were analyzed using ordered logit model.
Findings
This study shows the following results: (1) Chinese consumer confidence in domestic dairy products and trust in actors of the dairy chain are at a moderate-to-low level. (2) Government regulators are considered to take the most responsibility, with both an optimism-enhancing and a pessimism-reducing effect (the former effect is greater), while perceived trust in dairy farmers and retailers has little effect. (3) Perceived care has both an optimism-enhancing and a pessimism-reducing effect, and the former effect is stronger. Competence and openness have an optimism-enhancing effect and a pessimism-reducing effect, respectively. (4) The importance of the three dimensions of trust related to optimism-increasing and pessimism-reduction is limited, except in the case of government regulators.
Originality/value
This study contributes to a better understanding of consumer trust in food safety and also help demonstrate to the actors and institutions involved in the dairy supply chain the best way to improve the performance of their duties to meet the consumers' needs for safe and quality dairy products.
