Wrestling with Digital Objects and Technologies in Studies of Work

Studying technical work at digital interfaces, especially the work of engineers, poses challenges for ethnographers. In addition to the difficulties of understanding and documenting what engineers do at their computers, engineers use concepts and vocabularies that are foreign to social scientists without technical training. The authors describe the methods they developed over a decade to deal with these and related issues in their ethnographies of three engineering occupations: structural engineering, hardware engineering, and automotive engineering. Using dual observers, developing glossaries of technical terms, recording streams of behaviour, developing task tables, creating technology inventories, and creating databases of digital artefacts cross-referenced to one’s fieldnotes are among the 14 techniques discussed and illustrated.

Completeness praktikun learning tool in achieving competence automotive field would be a necessity that must be met. Seeing the large number of students at SMKN 1 Losarang, majoring in Automotive engineering, having practicum facilities that are still relatively minimal, with the limited practical facilities, additional practical facilities are needed in the form of car AC machine trainers to improve student competence at SMK N 1 Losarang. Increased competence by providing trainer AC Drives and conducted training and workshops and provide free test and post-test were conducted before and after the training. With the application of AC engine technology competence of students majoring in Automotive cars increased by 20.5%. This is based on comparison of the value of the free test to post-test value that has been done. PKM activity carried out has an impact enough for both students and the school's own department.

Effect of total quality management practices on nonfinancial performance: an empirical analysis of automotive engineering industry in Ethiopia

PurposeThe purpose of this study is to explore the total quality management (TQM) practices and identify their effect on the nonfinancial performance (NFP) in the automotive engineering industry in Ethiopia. Despite many studies investigating the relationship between TQM practices and NFP, rare research has been conducted on TQM in automotive industries, making this a hugely unexplored field.Design/methodology/approachThe data underlying this study was collected using more than 500 self-administered questionnaire survey, distributed to the employees working under different departments and factories under one automotive engineering industry. Extensive data screening and refinement processes for discarding irrelevant items for the questionnaire (Likert five-point scale) were carried out. The data was employed to test the proposed theoretical model, established with the objective of assessing the effect of TQM practices on the NFP in the case industry. Empirical validated relations have been proofed for previously done researches that there were positive relations between the TQM practices and NFP. Different statistical tools applied include descriptive data analysis, correlation analysis, mean scale test, reliability analysis and factor analysis, and finally, two models were developed based on structural equation modeling by using SPSS and AMOS-26 software.FindingsResults found in this study were quite surprising. Initially, there was a total of ten TQM factors. The six independent factors survived from factor analysis only two factors (employee involvement and innovation) were contributing to the NFP. The study was acted as a performance evaluation system to track the industry NFP. Although the study focused on the effect of TQM practices, for more results it is recommended to conduct a 360-degree further research study to reveal the weaknesses, strengths, opportunities and challenges of the case industry performance.Research limitations/implicationsEvery research has its own limitations. The way the analysis is conducted in this study ensures that the limitations do not compromise the validity of the results obtained. Control variables (industry type, size, age, process type and technology used) are not considered in the research which may affect the results obtained. The study included the automobile industry alone, so the obtained results cannot be generalized to other industries.Practical implicationsThe positive relationship between the TQM practices and NFP measures indicates the importance of each of these practices in improving the industry. Researchers/managers/practitioners can use this developed model periodically to understand where the industry stands in the quality management journey. They can also analyze the effect of TQM practices on financial as well as operational performance measures. The research findings can also motivate the top management of the industry for better planning of goals, to arrange resources in time, in pursuit of improving quality, employee and industry performance.Originality/valueThe Ethiopian manufacturing industry is required to improve their manufacturing and service quality, in order to enhance their productivity and boost their competitiveness in an international market, which is the basis of this study. This study signifies one of the first attempts to empirically explore this linkage between TQM and performance in the Ethiopian automotive industry context.

Optimal design of the vehicle mechatronic ISD suspension system using the structure-immittance approach

There are three types of two-terminal mechanical elements, namely the inerter, the spring, and the damper in the vehicle ISD suspension system, and how to design the suspension structure has drawn much attention in automotive engineering fields. Due to the advantage of using the external electrical network to simulate the corresponding mechanical impedance output, a ball-screw mechatronic inerter is adopted in the optimal design procedure in this paper. A half vehicle dynamic model considering the vehicle body vertical motion and pitch motion is established, and the optimal design methodology of the vehicle mechatronic ISD suspension is proposed by using the structure-immittance approach to ensure the simplicity of the suspension structures. The dynamic performance indexes constraints are taken into account, and the optimal structures are discussed in detail. Numerical simulations results show that, the dynamic performance indexes, namely the RMS (root-mean square) of the vehicle body vertical acceleration and the RMS of the pitch motion acceleration of the mechatronic ISD suspensions can be reduced by 31% and 35% without constraints, and 18% and 15% with constraints by comparing to the passive suspension system. The structure-immittance approach can be easily adopted in the vehicle suspension structural design, and the research fruits will provide a new thought for the application of the inerter element in automotive engineering.
