This paper employs human resources (HR) analytics to investigate the pathways through which high-potential managers ascend to C-suite positions, and how different developmental paths influence turnover among executives.

By combining job analysis and competency assessment with sequence analysis, the authors utilize HR analytics to analyze the work experiences of 53 general managers spanning 57 years (n = 2,742), encompassing various roles, job requirements, and 20 executive competencies attached to over 1,000 positions.

This study's findings reveal three distinct developmental paths that lead to the C-suite, characterized by differences in the content, context, timing, and complexity of work experience. Furthermore, the authors identify that a more complex developmental path tends to reinforce executives' competency in self-awareness while inhibiting their development of technical competency, ultimately resulting in reduced executive turnover.

By employing HR analytics to analyze empirical data embedded in job and organizational contexts, this study sheds light on the critical role of timing and complexity of work experiences in executive development. It also offers practical implications for firms seeking to optimize their leadership pipeline and reduce executive turnover by leveraging HR analytics effectively.

The purpose of this paper is to examine senior leadership behaviors across samples of Chinese, Indian, and Western chief executive officers (CEOs).

In this exploratory study, 101 CEOs from three different business contexts were interviewed to understand the leadership demands of widely different business and cultural contexts and the competencies associated with effective performance. The specific situations addressed by leaders were identified.

The authors found some common characteristics of outstanding CEOs across contexts, such as results orientation/achievement drive and forward thinking. There are also distinctive competencies manifested in the three cultures. While Indian CEOs are more likely to display consideration of the welfare of their nation in business decisions, Chinese CEOs uniquely influence for mutual benefit as well as criticizing themselves. Western CEOs, use interpersonal understanding and talent management.

Although the competencies observed are linked to performance by comparisons within each group of outstanding leaders, the authors were unable to obtain contrast groups of more typical leaders in India or China. The Western group was less rigorously defined, perhaps accounting for the less focused nature of their competencies and situations. This study nevertheless suggests that the cultural context is an important variable in leadership.

Leaders may use the paper's insights to suggest how they might expand their own repertoires, either in their own context or in dealing with organizations from other cultures.

This study contributes to the understanding of cross‐cultural management by identifying competencies that are unique to particular business contexts, as well as some that are common to the role.

In today's turbulent business environment leaders must be able to adapt to rapidly changing circumstances. For this research the authors aim to focus on the issue of adaptability defined as the ability to work effectively within a variety of changing situations, and with various individuals or groups. They also aimed to examine how variables of career complexity affect development of adaptability.

The authors draw on a unique database containing the career histories of 52 senior executives in a major global corporation. They use the term career complexity to represent the degree of variety in these individuals' career experiences, and they test the degree to which career complexity contributes to the development of adaptability later in their careers.

Findings from this study shed light on the relationship between specific career experiences and executive adaptability. Executives who had the experience to serve in an executive assistant role developed higher levels of adaptability. For executives without the executive assistant opportunity, job rotations through different types of roles provided a boost to their adaptability. Three role type changes (e.g. line, staff, or matrix) is optimal; 100 months is an optimal time to spend in each role type.

While the field of leadership development has generated substantial insight into the competencies required by executives, there are few models and empirical studies that describe the process of how specific competencies are developed. The authors' study highlighted the utility of the career complexity construct for both prospective understanding of career actions and processes and retrospective understanding of paths, patterns, and outcomes. The authors demonstrated the predictive value of the career complexity construct by presenting results of the statistical analyses of the hypothesized relationships between career complexity and career outcomes.

The purpose of this study is to investigate the influence of texture on hydrodynamic lubrication performance of slide surface from the perspective of skewness and kurtosis.

Hydrodynamic lubrication theoretical model of textured surface was established based on two-dimensional Reynolds equation, and finite difference algorithm was used as the numerical approach in the paper. Skewness and kurtosis of surface were obtained by discrete calculation.

Numerical analysis results show that the influence law of texture types on skewness, kurtosis and hydrodynamic lubrication was the more negative skewness and higher kurtosis, the better hydrodynamic lubrication performance when texture cross section contour and geometric parameters were the same. Similarly, the same influence law of skewness, kurtosis and hydrodynamic lubrication performance by texture cross-section contour was observed. However, it was unable to evaluate the effect of texture angle on hydrodynamic lubrication performance of textured surface from the perspective of skewness and kurtosis.

This paper confirms the feasibility of evaluating influence of texture types and texture cross-section contour on hydrodynamic lubrication performance from the perspective of skewness and kurtosis and provides a way to optimize texture type and texture cross section.

This paper aims to combine the grooves with an annular air thrust bearing with multi-hole restrictors and discusses the influence of the groove parameters on the bearing performance.

Four models of aerostatic bearings with grooves of different geometries are established. The pressure distribution, load-carrying capacity (LCC), stiffness and flow characteristics of the flow field in the bearing clearances are obtained by computational fluid dynamics simulation.

The numerical and simulation results show that air bearing with grooved restrictors can slow down the pressure drop at the air inlet and increase the LCC and stiffness of the bearing. The gas flow in the aerostatic bearing is also studied, and the air vortex in the recess is analyzed.

This research optimizes the structure of the annular air thrust bearing, analyzes the gas vortex in the recess, improves the LCC and stiffness of the bearing and provides a reference for the bearing in the selection of groove parameters.

This paper aims to carry out tribological experiments to explore the applications of femtosecond laser surface texturing technology on rock bit sliding bearing to enhance the lifetime and working performance of rock bit sliding bearing under high temperature and heavy load conditions.

Surface textures on beryllium bronze specimen were fabricated by femtosecond laser ablation (800 nm wavelength, 40 fs pulse duration, 1 kHz pulse repetition frequency), and then the tribological behaviors of pin-on-disc configuration of rock bit bearing were performed with 20CrNiMo/beryllium bronze tribo-pairs under non-Newtonian lubrication of rock bit grease.

The results showed that the surface texture on beryllium bronze specimens with specific geometrical features can be achieved by optimizing femtosecond laser processing via adjusting laser peak power and exposure time; more than 52 per cent of friction reduction was obtained from surface texture with a depth-to-diameter ratio of 0.165 and area ratio of 5 per cent at a shear rate of 1301 s−1 under the heavy load of 20 MPa and high temperature of 120°C, and the lubrication regime of rock bit bearing unit tribo-pairs was improved from boundary to mixed lubrication, which indicated that femtosecond laser ablation technique showed great potential in promoting service life and working performance of rock bit bearing.

Femtosecond laser-irradiated surface texture has the potential possibility for application in rock bit sliding bearing to improve the lubrication performance. Because proper micro dimples showed good lubrication and wear resistance performance for unit tribo-pairs of rock bit sliding bearing under high temperature, heavy load and non-Newtonian lubrication conditions, which is very important to improve the efficiency of breaking rock and accelerate the development of deep-water oil and gas resources.

Chinese S&T parks are one component of the Chinese system of innovation which has emerged over the last 20 years; they are not simply a copy‐paste of the American model. This paper aims to focus on this topic.

Developments were inferred from an extensive literature review (in English, in Chinese and in French) that was completed by an archive research as well as interviews of heads of Chinese S&T parks.

Six features make Chinese S&T parks different from what can be found elsewhere in the world: the Chinese people have the willingness to restore previous glory and share of the world economy; the Chinese government apparatus acts as the driving force with an overpowering impact; there are very few foreign companies in Chinese S&T parks – making those parks mostly inhabited by Chinese companies, but returnees play a significant role; an astonishing scale when benchmarked to European references; the greening of business has emerged as a new and powerful driver; and an evolutionary process is leading to the transformation of China into an innovative country.

This paper stands more as an essay reflecting the authors' understanding of the Chinese situation and, as such, it may be subjectively biased.

As Western managers are now considering China as a possible place to carry R&D, this paper helps them to get a better understanding of the features of the specific locations where they might implement their R&D labs.

The emergence of China as a technological country is a recent phenomenon. The authors have identified no such analysis in the published literature.

This study aims to solve the premature failure of the rubber stator due to wear, reduce the frictional resistance moment of the screw pump to solve the problem of a model of Daqing oilfield screw pump oil recovery system shutdown after the difficult start.

For the first time, the rotor surface of a screw pump was treated with dot-matrix texture to study the effect of dot matrix texture on the tribological performance of the stator-rotor friction subsets of screw pump. Reciprocating friction tests with different texture morphologies (S-shape, double tongue) and angular parameters (0°, 45° and 90°) were conducted at 10% of the texture area and pump silicone grease.

When point texture was added to the surface of the rotor sample, the friction coefficient and wear quantity of the sample were lower than those of the surface without texture treatment, and the double tongue 0° combination showed the best tribological properties. At this time, the average coefficient of friction and wear is reduced by 22.8% and 62%, 28.6% and 64.8%.

The introduction of texture can effectively improve the tribological performance of progressive screw pumps, and this paper provides important theoretical and experimental support for the design of progressive screw pumps in practical applications.

The purpose of this paper is to offer novel and complementary insights into the relationship between product modularity and product innovation by investigating the mediating role of module suppliers' relationship-specific investments which include both property-based relationship-specific investment (PRSI) and knowledge-based relationship-specific investment (KRSI).

This paper is an empirical study based on structural equation modelling, with a sample of 121 core firms of high-tech modular cooperation in China.

The findings indicated that product modularity had a significant positive effect on product innovation; product modularity was positively related to module suppliers' PRSI; module suppliers’ KRSI had a direct effect on product innovation while PRSI had an indirect effect on product innovation through KRSI; the relationship between product modularity and product innovation was serially multi-mediated by module suppliers’ PRSI and KRSI.

Modular product design and modular cooperation governance guidance for core firms and cooperative investment strategies guidance for module suppliers were provided.

This study is the first attempt to analyse how product modularity affects product innovation in the context of inter-firm modular cooperation by revealing the mediating role of module suppliers' relationship-specific investments.
