试论岩芯钻探中复杂地层的护孔工艺

复杂地层的护壁与堵漏,长期以来,一直是钻探工作的技术关键之一。它不仅影响钻探生产的效率,同时也影响钻探工程的质量。特别是小口径钻进,如何顺利通过复杂地层,充分发挥小口径金刚石钻进优质、高效的特点,更具有现实意义。岩心钻探中处理复杂地层最基本的技术措施就是使用泥浆护孔。实践证明,钻进中遇到坍塌掉块、膨胀缩径、漏水、涌水或膏盐等地层,如能正确使用泥浆,在很大程度上可以防止或减轻复杂情况的发生。本文通过对复杂地层的分析,阐述了护孔堵漏工艺的具体实施方法,提出改善护孔技术的建议,为今后的相关工作提供思路。     

Project manager's emotional intelligence and project performance: The mediating role of project commitment

Emotional intelligence is considered to be important for project managers to affect project performance, but emotional intelligence does not always play an effective role. Based on conservation of resource theory, this article explores the impact of project managers’ emotional intelligence on project performance. The results show that the emotional intelligence of project managers affects project performance through the mediating effect of project commitment, and project complexity negatively moderates the impact of project managers’ emotional intelligence on project commitment. This article provides practical guidance on how project managers can handle emotional intelligence in different complex situations and serves as a reference for the selection and appointment of project managers in complex projects.

A socio-cognitive approach to leading a learning project team: A proposed model and scale development

This article proposes a theoretical model and measurement scale for leading a learning project team. While leadership is largely recognized as one of the most important mechanisms for transferring learning from individuals to projects, there lacks a succinct measurement scale for project members to report on project leaders’ behaviors that promote collective learning in projects. Drawing from rich theories on multilevel learning, socio-cognitive conflicts, and leading diversity, we develop a measurement scale that captures project members’ experiences of how their leaders (a) support the identification and communication of project members’ individual mental models, (b) support the resolution of differences in mental models among project team members, and (c) create opportunities and time for team members to interact with others outside the project team. Collectively, these three dimensions form a new scale for leading a learning project team. We cautiously conclude sound psychometric measurement properties from an initial sample of 94 valid responses to a questionnaire distributed to project members through international professional project management networks. This study highlights the multi-level nature of leading a learning project team and provides tentative empirical support for the reflective three-dimensional scale predicting learning in project teams better than transformational leadership.     

Does project management matter? The relationship between project management effort,complexity, and profitability

The purpose of this study is to explore the causal impact of project management effort on project profitability (i.e., profit on sales) for varying degrees of project complexity in an engineer-to-order (ETO) project setting. We use a sample of 917 projects’ status reports of a large firm that offers ETO products coupled with a control function approach to empirically investigate the causal effect of project management effort on projects’ profitability. Furthermore, we investigate the marginal impact of project management effort and its effect for different degrees of project complexity. Our results reveal a positive but diminishing impact of project management effort on project profitability. Furthermore, we find that higher project complexity jeopardizes project profitability. However, project management's marginal impact increases with increasing project complexity, ultimately leading to higher returns of more complex projects. While previous research provided correlational evidence between project management and project success, this study is, to the best of our knowledge, the first to demonstrate a causal impact of project management on profitability. The results offer unique insights into the economic benefits of project management while taking into account the complexity of the projects. The study confirms the benefits of project management efforts regarding project profitability and underlines the high relevance of project management for complex projects, thereby underlining the importance of contingency theory. It shows that firms can compensate higher ETO customization and higher project complexity through higher project management effort.

Examining the role of transformational leadership of portfolio managers in project performance

Research into the role of transformational leadership in project based organisations has generally focused on project managers or senior managers and less so on portfolio managers who oversee multiple projects to achieve business objectives. This study examines the impact of transformational leadership behaviour of portfolio managers on project performance directly and indirectly through other intervening variables such as climate for innovation and innovation championing. Using a questionnaire survey, data were obtained from 112 project managers in a UK project based organisation. Transformational leadership behaviour of portfolio managers was found to have a positive and significant relationship with project performance. Innovation championing and climate for innovation both partially mediated the relationship between transformational leadership and project performance. The study confirms the importance of portfolio managers in enhancing project performance and identifies the need for project based organisations to cultivate transformational leadership behaviour among them for enhanced performance. It also highlights the need for further exploration of the role of portfolio managers in improving project performance.     

建筑业项目经理领导有效性研究

关于领导有效性的研究较多,但对建筑业这一特定行业的研究却很少。本文针对建筑业项目经理这一特定群体选取适当的绩效指标,从关心员工和关心任务这两个领导行为的基本维度研究其领导有效性。研究发现,领导行为对项目绩效有显著影响,“高关心员工、高关心任务”的领导类型最为有效,而任务导向型和员工导向型项目经理的领导有效性会因评价指标选取的不同而存在差异。本研究可为项目经理调整领导行为、提高领导有效性提供参考。
