Abstract

Purpose

The purpose of this paper is to determine the value of I‐Ching (also called Book of Changes), the ancient Chinese book of wisdom, which has been used for thousands of years to help people make decisions in daily life. Recently, eastern and western scholars have begun discussing how to apply the wisdom of I‐Ching to the field of business administration, particularly decision‐making practices.

Design/methodology/approach

A content analysis method was adopted to uncover possible modern management decision‐making constructs. The single words approach did not find frequently appearing words that integrated decision‐making constructs in the context of I‐Ching. Further uncovering I‐Ching's administrative decision‐making approach, the managerial decision‐making model of I‐Ching is explained, including the premises, the decision contingencies, and the decision process.

Findings

By using an academic comparative analysis method, as it applies to managerial decision making, I‐Ching's early management decision‐making model is subsequently compared with western management decision models, which include rational decision making, bounded‐rationality decision making, intuitive decision making, implicit favorite decision making, and garbage‐can decision making.

Research limitations/implications

The majority of scholars that study I‐Ching focus on “practice divination” research, paying attention to the interpretation or critique of the text only. Unfortunately, related literature based upon a social science research foundation is limited.

Originality/value

The value of I‐Ching was determined to lie in allowing flexibility in the decision‐making process.

Abstract

Purpose

Supermarket promotions typically use a standard label, which displays the regular price, discounted price and discounted unit price. Visits to supermarkets across multiple countries found that none used a price label that also contains the regular (i.e. pre-discounted) unit price. This study aims to investigate the effectiveness of a dual unit-price label that includes the regular unit price as a reference price, and what underpins its efficacy in enhancing promotion attractiveness.

Design/methodology/approach

The authors executed four studies, supported by three supplemental studies. Study 1 established external validity through a natural instore experiment. Studies 2 and 3 tested the dual unit-price label with different pack sizes and assortment sizes, respectively. Finally, Study 4 tested the underpinning mechanism of the efficacy of the dual unit-price label.

Findings

In Study 1, daily sales records over four weeks showed that dual unit-price label promotions had larger sales volume than standard-label promotions. Study 2 showed a larger pack size, a heuristic cue for greater economy and increased preference for dual unit-price label promotions. Study 3 similarly found that the dual unit-price label was preferred more as cognitive load was increased by assortment size. Finally, Study 4 demonstrated the dual processing of the dual unit-price label, using a conscious preference measure (information provided) and an unconscious implicit attitude test.

Research limitations/implications

Unit-price research has mainly considered a cognitive process. The authors demonstrated the importance of considering a heuristic process.

Practical implications

Supermarkets can use this simple and yet effective tool to improve promotion effectiveness.

Originality/value

This study demonstrates that the dual unit-price label is a new and easy tool to enhance sales promotions, which academic research and managerial practice had never considered previously.

Abstract

Purpose

Time pressure is the most common kind of work pressure that employees face in the workplace; the existing research results on the effect of time pressure are highly controversial (positive, negative, inverted U-shaped). Especially in the era of knowledge economy, there remains a research gap in the impact of time pressure on individual knowledge hiding. The purpose of this paper is to explore the impact of different time pressure (challenge and hindrance) on knowledge hiding and to explain why there is controversy about the effect of time pressure in the academics.

Design/methodology/approach

The authors collected two waves of data and surveyed 341 R&D employees in China. Moreover, they used regression analysis, bootstrapping and Johnson–Neyman statistical technique to verify research hypotheses.

Findings

The results show that challenge time pressure (CTP) has a significant negative effect on knowledge hiding, whereas hindrance time pressure (HTP) has a significant positive effect on knowledge hiding; job security mediates the relationship between time pressure and knowledge hiding; temporal leadership strengthen the positive impact of CTP on job security; temporal leadership can mitigate the negative impact of HTP on job security.

Originality/value

The findings not only respond to the academic debate about the effect of time pressure and point out the reasons for the controversy but also enhance the scholars’ attention and understanding of the internal mechanism between time pressure and knowledge hiding.

Abstract

Purpose

Maneno mengi yanayohusu haki za binadamu na haki za kiteknolojia hayajatafsiriwa katika lugha ya Kiswahili. Kwa hivyo, wataalamu wa teknolojia na watetezi wa haki za kidijitali hutumia maneno ya Kiingereza – hata bila utohozi – wanapozungumzia haki za kiteknolojia. Hali hii ya mambo inachangia udhoofu fulani katika utetezi wa haki za kidijitali kwani wanaojaribu kueleza jamii umuhimu wa haki hizi hulazimishwa kutegemea msamiati wa Kiingereza usiyo na msingi au viungo na lugha ya Kiswahili Katika makala hii, tutazungumzia umuhimu wa kukaribisha watu kutumia lugha za Kiafrika kwenye mtandao.

Design/methodology/approach

Kiswahili ni lugha ya Kiafrika inayozungumzwa katika eneo zaidi sana duniani. Karibu watu milioni mia moja na arobaini Afrika mashariki wanazungumza Kiswahili kama lugha yao ya kwanza au ya pili, miongoni mwao Wakenya na Watanzania, wenyeji wa nchi ambamo Kiswahili ni lugha ya kitaifa. Tena kuna historia ndefu ya kutumiwa kwa lugha ya Kiswahili katika uandishi, uchapishaji na ubunifu wa utamaduni wa kisasa. Kiswahili pekee yake ndiyo lugha ya asili ya Kiafrika inayotumika kama lugha ya maalum ya Umoja wa Mataifa za Kiafrika. Hata hivyo, kwa upande wa matumizi ya Kiswahili, hasa kwenye mada ya teknolojia, Kiswahili imewachwa nyuma.

Findings

Zaidi ya maneno rasmi, uwepo wa lugha za Kiafrika ni muhimu kuimarisha jumuiya za Kiafrika mtandaoni kwani lugha inalenga sana haki na utambulisho wa watu. Miradi za kutafsiri maneno za kiteknolojia katika lugha ya Kiswahili inahimiza jumuiya za Afrika Mashariki kuunda jamii inayosimamia matakwa yao vyema. Makala hii basi inazingatia umuhimu wa lugha kwenye kuunda jamii na katika hatua za kuondoa mbinu za kikoloni mtandaoni ili wenyeji wa Afrika Mashariki wajione mtandaoni kwa ujumla wao wote. Makala pia itazingatia semiotiki ya lugha katika ubunifu wa teknolojia, na umuhimu wa kutafsiri jamii ya lugha ya Kiswahili katika harakati za kuondoa ukoloni katika ubunifu huu. Lakini sio tu kwamba lugha ya Kiswahili ndio pekee inayoweza kuondoa mbinu za kikoloni mtandaoni, kwani pia lugha hiyo ina ishara za kutawalwa kwa jamii fulani. Bali makala hii inatumia mfano wa Kiswahili kuhimiza utumiaji wa lugha za kiasili au za kimama mtandaoni ili kulinda mustakabali wa kidijitali wa umma.

Originality/value

Umuhimu wa makala hii ni kuashiria jipya umuhimu wa lugha katika harakati za kuendeleza haki za kidijitali na hasa kuondoa mbinu za kikoloni kwenye teknolojia, swala lisilowahijadiliwa katika lugha ya Kiswahili.

Abstract

Purpose

Sufficient sample data are the necessary condition to ensure high reliability; however, there are relatively poor fatigue test data in the engineering, which affects fatigue life's prediction accuracy. Based on this, this research intends to analyze the fatigue data with small sample characteristics, and then realize the life assessment under different stress levels.

Design/methodology/approach

Firstly, the Bootstrap method and the principle of fatigue life percentile consistency are used to realize sample aggregation and information fusion. Secondly, the classical outlier detection algorithm (DBSCAN) is used to check the sample data. Then, based on the stress field intensity method, the influence of the non-uniform stress field near the notch root on the fatigue life is analyzed, and the calculation methods of the fatigue damage zone radius and the weighting function are revised. Finally, combined with Weibull distribution, a framework for assessing multiaxial low-cycle fatigue life has been developed.

Findings

The experimental data of Q355(D) material verified the model and compared it with the Yao’s stress field intensity method. The results show that the predictions of the model put forward in this research are all located within the double dispersion zone, with better prediction accuracies than the Yao’s stress field intensity method.

Originality/value

Aiming at the fatigue test data with small sample characteristics, this research has presented a new method of notch fatigue analysis based on the stress field intensity method, which is combined with the Weibull distribution to construct a low-cycle fatigue life analysis framework, to promote the development of multiaxial fatigue from experimental studies to practical engineering applications.

Abstract

Purpose

The aim of this paper is to present the rationale, a numerical example and a case study of the application of an algorithm to convert non‐calendar based preventive maintenance (PM) schedules into calendar‐time format for semiconductor manufacturing systems (SMS). The resulting calendar‐time PM schedules can be utilized as a baseline within a PM scheduling optimization process.

Design/methodology/approach

The algorithm utilizes estimations of work‐in‐process (WIP) and system parameters to estimate an equivalent calendar‐time schedule for PM schedules based on different units. A numerical example based on fictitious data illustrates the utilization of the conversion algorithm within a mixed PM scheduling scenario, including wafer, processing‐time and energy‐based PM tasks for multi‐chamber tools. In addition, a case study illustrates the accuracy of the algorithm by comparing estimated PM targets (i.e. due, warning and late dates) with historical data from a real semiconductor fabrication facility.

Findings

Results from the case study validated the conversion algorithm by showing accurate estimations of PM targets (i.e. due, warning and late dates). The accuracy of the algorithm depends, however, on good estimates for WIP levels within the planning horizon.

Originality/value

The conversion algorithm may be utilized not only in SMS but also in other industries that require the conversion of non‐calendar based PM schedules into calendar‐time format for PM optimization and operational purposes.

Abstract

Purpose

Based on the error analysis, the authors proposed a new kind of high accuracy boundary element method (BEM) (HABEM), and for the large-scale problems, the fast algorithm, such as adaptive cross approximation (ACA) with generalized minimal residual (GMRES) is introduced to develop the high performance BEM (HPBEM). It is found that for slender beams, the stress analysis using iterative solver GMRES will difficult to converge. For the analysis of slender beams and thin structures, to enhance the efficiency of GMRES solver becomes a key problem in the development of the HPBEM. The purpose of this paper is study on the preconditioning method to solve this convergence problem, and it is started from the 2D BE analysis of slender beams.

Design/methodology/approach

The conventional sparse approximate inverse (SAI) based on adjacent nodes is modified to that based on adjacent nodes along the boundary line. In addition, the authors proposed a dual node variable merging (DNVM) preprocessing for slender thin-plate beams. As benchmark problems, the pure bending of thin-plate beam and the local stress analysis (LSA) of real thin-plate cantilever beam are applied to verify the effect of these two preconditioning method.

Findings

For the LSA of real thin-plate cantilever beams, as GMRES (m) without preconditioning applied, it is difficult to converge provided the length to height ratio greater than 50. Even with the preconditioner SAI or DNVM, it is also difficult to obtain the converged results. For the slender real beams, the iteration of GMRES (m) with SAI or DNVM stopped at wrong deformation state, and the computation failed. By changing zero initial solution to the analytical displacement solution of conventional beam theory, GMRES (m) with SAI or DNVM will not be stopped at wrong deformation state, but the stress error is still difficult to converge. However, by GMRES (m) combined with both SAI and DNVM preconditioning, the computation efficiency enhanced significantly.

Originality/value

This paper presents two preconditioners: DNVM and a modified SAI based on adjacent nodes along the boundary line of slender thin-plate beam. In the LSA, by using GMRES (m) combined with both DNVM and SAI, the computation efficiency enhanced significantly. It provides a reference for the further development of the 3D HPBEM in the LSA of real beam, plate and shell structures.

Abstract

Purpose

This paper aims to analyze the morphology transformation on the Cu3Sn grains during the formation of full Cu3Sn solder joints in electronic packaging.

Design/methodology/approach

Because of the infeasibility of analyzing the morphology transformation intuitively, a novel equivalent method is used. The morphology transformation on the Cu3Sn grains, during the formation of full Cu3Sn solder joints, is regarded as equivalent to the morphology transformation on the Cu3Sn grains derived from the Cu/Sn structures with different Sn thickness.

Findings

During soldering, the Cu3Sn grains first grew in the fine equiaxial shape in a ripening process until the critical size. Under the critical size, the Cu3Sn grains were changed from the equiaxial shape to the columnar shape. Moreover, the columnar Cu3Sn grains could be divided into different clusters with different growth directions. With the proceeding of soldering, the columnar Cu3Sn grains continued to grow in a feather of the width growing at a greater extent than the length. With the growth of the columnar Cu3Sn grains, adjacent Cu3Sn grains, within each cluster, merged with each other. Next, the merged columnar Cu3Sn grains, within each cluster, continued to merge with each other. Finally, the columnar Cu3Sn grains, within each cluster, merged into one coarse columnar Cu3Sn grain with the formation of full Cu3Sn solder joints. The detailed mechanism, for the very interesting morphology transformation, has been proposed.

Originality/value

Few researchers focused on the morphology transformation of interfacial phases during the formation of full intermetallic compounds joints. To bridge the research gap, the morphology transformation on the Cu3Sn grains during the formation of full Cu3Sn solder joints has been studied for the first time.
