This paper aims to examine knowledge management (KM) processes and its implementation in the public sector in China and seeks to identify success factors that influence KM and attempts to address various key issues in the process in a hope to raise awareness of KM as a potential solution to improve the performance in the public sector.

A case study and research experience are presented.

The study suggests that KM in the public sector still in its infancy and has a long way to go in the KM journey. However, the study has identified a certain number of factors that are essential to the success of the KM initiative and program in the public sector, of which, the appropriateness and effectiveness of knowledge sharing is more important in the public sector than in the private sector. The study examines current situation in terms of KM activities in the public sector in China and fuelled the debate concerning KM in the public sector.

The outcome of the research could have significant implications for KM programs in public sector organizations in China.

This study is a comprehensive examination and analysis of the process of KM and its implementation in the public sector in China, incorporating both the cultural and organizational factors that play a role in the whole process. The paper describes and develops a framework of KM processes and implementation in the public sector as well as recommendations to practitioners about planning and implementing KM programs and initiatives.

Three-dimensional (3D) printing provides more possibilities for composite manufacturing. Composites can no longer just be layered or disorderly mixed as before. This paper aims to introduce a new algorithm for dual-material 3D printing design.

A novel topology design method: solid isotropic material with penalization (SIMP) for hybrid lattice structure is introduced in this paper. This algorithm extends the traditional SIMP topology optimization, transforming the original 0–1 optimization into A–B optimization. It can be used to optimize the spatial distribution of bi-material composite structures.

A novel hybrid structure with high damping and strength efficiency is studied as an example in this work. By using the topology method, a hybrid Kagome structure is designed. The 3D Kagome truss with face sheet was manufactured by selective laser melting technology, and the thermosetting polyurethane was chosen as filling material. The introduced SIMP method for hybrid lattice structures can be considered an effective way to improve lattice structures’ stiffness and vibration characteristics.

The fabricated hybrid lattice has good stiffness and damping characteristics and can be applied to aerospace components.

Human group behavior is the driving force behind many complex social and economic phenomena. Few studies have integrated multi-dimensional travel patterns and city interest points to construct urban security risk indicators. This paper combines traffic data and urban alarm data to analyze the safe travel characteristics of the urban population. The research results are helpful to explore the diversity of human group behavior, grasp the temporal and spatial laws and reveal regional security risks. It provides a reference for optimizing resource deployment and group intelligence analysis in emergency management.

Based on the dynamics index of group behavior, this paper mines the data of large shared bikes and ride-hailing in a big city of China. We integrate the urban interest points and travel dynamic characteristics, construct the urban traffic safety index based on alarm behavior and further calculate the urban safety index.

This study found significant differences in the travel power index among ride-sharing users. There is a positive correlation between user shared bike trips and the power-law bimodal phenomenon in the logarithmic coordinate system. It is closely related to the urban public security index.

Based on group-shared dynamic index integrated alarm, we innovatively constructed an urban public safety index and analyzed the correlation of travel alarm behavior. The research results fully reveal the internal mechanism of the group behavior safety index and provide a valuable supplement for the police intelligence analysis.

By studying four public universities in Egypt, the author of this paper aims to identify how male faculty perceive the representation and status of their female colleagues.

The author employed a qualitative research method via semi-structured interviews with 40 male academics in addition to five focus group discussions with an additional 20 male academics. The author subsequently used thematic analysis to determine the main ideas in the transcripts.

The findings confirmed that women faculty are not under-represented at professorial levels, but they are denied administrative academic positions, such as rectors and deans in universities. The author also discovered that the social norms shaping both national and organizational culture in Egypt create a cultural bias against women faculty.

To the best of the author's knowledge, this study is the first of its kind in the context of a developing nation to focus on the status and representation of women faculty from the perspective of male colleagues, and subsequently, it is the first to address the higher education sector in one of the leading developing nations in Africa and the Middle East. This paper contributes by filling a gap in HR management and higher education, in which empirical studies that address male faculty to identify their perceptions of the status and representation of their female colleagues have been limited so far.
