This paper aims to present an iterative path-following method with joint limits to solve the problem of large computation cost, movement exceeding joint limits and poor path-following accuracy for the path planning of hyper-redundant snake-like manipulator.

When a desired path is given, new configuration of the snake-like manipulator is obtained through a geometrical approach, then the joints are repositioned through iterations until all the rotation angles satisfy the imposed joint limits. Finally, a new arrangement is obtained through the analytic solution of the inverse kinematics of hyper-redundant manipulator. Finally, simulations and experiments are carried out to analyze the performance of the proposed path-following method.

Simulation results show that the average computation time is 0.1 ms per step for a hyper-redundant manipulator with 12 degrees of freedom, and the deviation in tip position can be kept below 0.02 mm. Experiments show that all the rotation angles are within joint limits.

Currently , the manipulator is working in open-loop, the elasticity of the driving cable will cause positioning error. In future, close-loop control based on real-time attitude detection will be used in in combination with the path-following method to achieve high-precision trajectory tracking.

Through a series of iterative processes, the proposed method can make the manipulator approach the desired path as much as possible within the joint constraints with high precision and less computation time.

This paper aims to provide readers with a comprehensive overview of the current state of the millennial literature, highlighting the significance and challenges of millennial professionals, their reported high turnover and the various recommendations designed to engage and retain them.

An integrated review approach was applied to synthesise contemporary peer-reviewed articles, supplemented by legacy and grey literature and relevant book chapters, to comprehensively explore and construct a cohesive overview of the current research on the millennial workforce.

Within the wealth of available information, examining the various studies on millennial turnover reveals diverse theories, evidence and opportunities for advancement, underscoring the necessity for more robust empirical studies. The investigation identified three overarching retention strategy themes: (1) intergenerational conflict management, (2) workplace adaptations and (3) solutions rooted in a protean career orientation. In alignment with protean career concepts, coaching shows promise as an underexplored option.

This article holds practical significance by offering researchers a comprehensive and cohesive overview of the millennial literature. Additionally, it gives organisations a novel perspective on the crucial role coaching can play in engaging and retaining millennial employees.

The increased focus on retaining millennial workers in recent decades has spurred a proliferation of articles and books on this subject. However, this body of research remains fragmented, lacking an overview that provides a clear picture of its current state. This review aims to bridge this gap.

The purpose of this paper is to identify essential psychological-informed executive coaching approaches that enhance the organisational learning and development process and outcomes through integrating existing research evidence. Since coaching has been widely used in leadership development related areas and previous studies confirmed that this generates positive effects on individual-level learning in the organisational setting. The identified frameworks and influential factors outlined in this paper can serve as explicit guidelines for the organisation and management team when setting selection and evaluation benchmarks for employing executive coaches.

An integrated review approach was applied to narratively synthesise 234 (k=234) identified peer-review articles between 1995 and 2018. This review followed a rigorous protocol that the authors consulted ten (n=10) experts in the field. Both qualitative and quantitative psychological-focused research evidence was included in this study.

First, certain psychological approaches, such as cognitive behavioural, solution-focused, GROW and strength-based approaches, were highlighted in current research evidence. Second, the essential factors and skills, for instance, building trust, transparency and rapport, and facilitating learning were identified. Third, the main organisational learning and development outcome evaluation methods were outlined in this review, such as the self-efficacy scale, organisational commitment, workplace psychological well-being, 360-degree feedback and the Multifactor Leadership Questionnaire.

It is always challenging to integrate research evidence on coaching because of the diversity of theoretical disciplines upon which coaching interventions draw. Therefore, it is difficult to generate a meta-analytic review which can generate statistical results. This review also reveals room for improvement in the quality of existing coaching evidence in accordance with the criteria for evidence-based management or practice (Briner et al., 2009), such as research methodology and evaluation design. Moreover, there is a lack of evidence on this reflective process which helps professional coaches to ensure the quality of their practice and organisational support.

This review offers a new perspective on the role psychology plays in the organisational learning and development practices. The identified coaching approaches, influential interpersonal skills and outcome evaluation methods can serve as practical guidelines when applying external coaching to facilitate a better organisational learning and development process and outcome.

This is the first literature review to focus on contemporary psychological-informed coaching evidence (between 1995 and 2018) in the workplace setting. Despite the rapid growth in demand for professional coaching practitioners (International Coach Federation, 2016), there is a lack of research-informed evidence to overcome the challenges faced by organisations when employing external coaches, such as what selection criteria or evaluation benchmarks to use. This review takes a practical perspective to identify essential body of knowledge and behavioural indicators required for an executive coach to facilitate an effective learning and development outcome.
