The purpose of this study is to map the implications and competencies for Industry 4.0 to the hard and soft aspects of total quality management (TQM).

The author/s collected data from purposively drawn samples of early-career engineering professionals (ECEPs) using a cross-sectional survey. A total of 20 ECEPs from three small-class cohorts (2014, 2016 and 2018) participated in the survey. The author/s analyzed data using the Kruskal–Wallis test and Wilcoxon–Mann–Whitney test to establish the effect of cohort and gender on the implications and competencies for Industry 4.0. The author/s then mapped the top- and bottom-ranked implications and competencies onto the hard and soft aspects of TQM using a matrix.

Based on the cohort, significant differences p < 0.05 existed in the interests and competencies for Industry 4.0. In congruence, the 2014 cohort had the highest number of “unique” top- and bottom-ranked competencies and implications spanning the hard and soft TQM. Based on gender, nonsignificant differences p < 0.05 existed in the interests and competencies for Industry 4.0. The male and female ECEPs' “common” top-ranked implications appeared under the hard and soft TQM. All their “common” top-ranked competencies appeared under the hard TQM, while all their “common” bottom-ranked competencies appeared under the soft TQM.

The sample size, context/discipline and perceptual data are limitations.

Optimizing an existing TQM framework/matrix to design Industry 4.0 TQM, advanced as TQM 4.0.

Perspectives of early-career professionals for TQM 4.0 implementation.

Study location may cause a different type of socio-demographic, body mass index (BMI), study intensity and food-related behavior. The increasing number of Indonesia students who study abroad to Taiwan is interesting to be examined those factors related. The purpose of this study is to examine the food-related behavior of Indonesian college students in different study location.

A descriptive cross-sectional study design was used to administer questionnaires assessing socio-demographic, BMI, study intensity, meal preparations, food access and eating behavior of Indonesian college students (n = 493). Study location took in two cities and different countries (Indonesia and Taiwan). Analysis statistics was using frequency descriptive, Chi-square test, Wilcoxon–Mann–Whitney U test, Kruskal–Wallis test and Logistic regression.

The trend showed students who lived in Malang tended to have healthier eating behavior. Students tended to have a higher prevalence of low study intensity, dependent meal preparation and difficult food access in Taipei. There was a significant relationship between study location and study intensity (p < 0.01), study location and BMI (p < 0.01), study location and meal preparation (p < 0.01), study location and food access (p = 0.02). On the other hand, eating behavior had no significant relationship with study location (p = 0.28). Marital status became the most dominant variable in influencing obesity (OR = 0.198). Findings indicate that there are significant differences between study location with marital status, BMI, study intensity, meal preparation and food access, but not eating behavior. Moreover, married status is most influencing to obesity risk.

The limitations of this research were data of height and weight was not be measured directly. Moreover, the reliability of the instrument was unexpected. In the future, research needs improvement more sample for fixing it. Moreover, to support initiatives to incorporate eating behavior into body weight management strategies may be needed. The implications are to create an effective nutrition education for Indonesian college students. Hopefully, it will be influencing public attitudes and affecting the quality of life.

Further investigation should consider longitudinal studies to explore the different effects of eating behavior on overweight and obesity. Nutritional education programs should give to young adults not only in developed but also in developing countries.

This paper shows our findings about the difference study location that may cause a different type of eating behavior. The research subject was Indonesian college students who live and study in two cities, Malang-Indonesia and Taipei-Taiwan. The trend showed students who live in Malang tend to have healthier eating behavior. On the other hand, study intensity, meal preparation and food access were significantly different in both cities. Indonesian college students in Taipei tended to have the higher prevalence of low study intensity, dependent meal preparation and difficult food access. The authors believe that the findings would appeal to a broad audience, especially for improving meal preparation in college students who study abroad.

The purpose of this study is to analyze market inefficiencies in the market for cryptocurrencies by providing a comprehensive analysis of short-term (over)reactions that follow significant price changes of such currencies.

This study identifies and analyzes overreactions and mispricing in markets for cryptocurrencies by applying a broad set of thresholds that depend on market-specific dynamics and volatilities. This study also analyzes the returns on days following abnormal returns and identifies significant differences from normal returns using the t-test and the Mann–Whitney U-test. The researchers further complement the literature by using end-of-the-day returns in addition to high-low returns. Additionally, this study considers a broad sample of 50 cryptocurrencies for an expanded time span (2015–2020) that includes the big currencies as well as smaller currencies.

Findings detect the existence of overreactions and, thus, market inefficiencies in crypto markets. The findings for different methodological approaches are similar, which underpins the robustness of the findings. By considering a broad sample that includes small and big currencies, we can show the existence of a market size effect. By considering a broad set of thresholds, the authors further found evidence for a magnitude effect, which means that higher initial abnormal returns are related to higher inefficiencies.

This paper has practical implications. Market inefficiencies were detected, which can be used in practical trading to obtain excess returns. In fact, methodological approach of this study and its results can be used to derive a strategy for trading in cryptocurrencies that can be easily implemented. Based on the study’s findings, the authors can expect positive access returns by applying this trading strategy.

The authors complement the literature on market inefficiencies and mispricing in crypto markets by analyzing price patterns after initial abnormal returns. Researchers contribute by applying different methodological approaches in addition to the approaches used so far, by considering a set of different thresholds and by applying a much broader data set that enables the study to analyze additional aspects.

This paper focuses on the influence of social, cultural and religious factors on investors' attention. In particular, the authors examined if the attention-grabbing mechanism works on Sundays, that is, if the Italians' Sunday activities and habits lead to a lower attention to second-hand financial news, compared to Saturdays.

The authors analyzed the market reaction to equivalent stale events published on the Saturday and Sunday editions of an Italian financial newspaper and conducted a standard event study on abnormal returns and abnormal volumes for Saturday and Sunday columns and a multivariate analysis on abnormal returns for columns reporting positive recommendations. As a robustness check, the authors performed a sentiment analysis of the columns and included this variable in the regression analysis, but sentiment proved to be not significant in the final model.

The study’s results confirmed that the attention-grabbing mechanism directed buying decisions, while had no influence on selling decisions. Furthermore, event study and multivariate analysis showed a significant lower market reaction to Sunday columns, supporting the study hypothesis of a Sunday investors' inattention which can be traced to cultural and/or religious factors since Sunday in Italy is a day devoted to family, entertainment and religious rituals.

The lower investors' attention on Sundays and the related influence of social, cultural and religious factors have implications for the timing of both corporate communications and financial advertising.

The authors’ paper provides an original contribution, on the empirical ground, to the attention-grabbing theory and to the growing theoretical literature in microeconomics that models attention.

The purpose of this paper is to illuminate light on the assessment of operating efficiency of specialty coffee retailers from the perspective of socially responsible global sourcing. This paper evaluates the impact of socially responsible sourcing on the operating efficiencies of specialty coffee retailers before and after implementing fair‐trade practices and compares the operating efficiencies of fair‐trade coffee retailers to those of non‐fair‐trade coffee retailers.

The paper proposes data envelopment analysis (DEA) to measure the comparative efficiency of seven specialty coffee retailers, relative to prior periods and their key competitors. It develops the Charnes‐Cooper‐Rhodes (CCR) model that is designed to derive weights without their being fixed in advance. The CCR version of DEA is adopted to assess the impact of the coffee retailers' policy initiatives (i.e. fair‐trade practices) on their efficiency and measure the change over time (i.e. before and after fair‐trade practices) efficiency of the coffee retailers. As a post hoc DEA analysis, it also performs non‐parametric rank sum statistical tests for any discernable group differences between fair‐trade coffee retailers and non‐fair‐trade coffee retailers.

The study found that a group of coffee retailers committed to socially responsible sourcing (i.e. fair‐trade) practices tended to perform significantly better than the group which has yet to commit socially responsible sourcing practices with a concern over increased purchasing price. Also, it was found that a premium purchasing price paid to fair‐trade coffee beans did not undermine the coffee retailer's comparative operating efficiency despite its adverse impact on purchasing cost. In other words, a cost increase resulting from socially responsible business conducts might have been offset by the revenue increase resulting from favorable brand recognition attached to social responsibility.

This study is the first attempt to assess the impact of socially responsible sourcing practices on the multinational firms (MNFs) such as specialty coffee retailers' competitiveness and then investigate whether the MNF's commitment to socially responsible sourcing practices can be developed into its long‐term strategic weapon. In addition, it helps specialty coffee retailers formulate future global sourcing strategies by providing the detailed picture of how socially responsible sourcing can impact their competitiveness.

Transaction costs arise from economic exchange rather than production activities. However, the term “transaction cost” is not consistently defined in the construction industry because the concept of transaction cost is not universally accepted by all stakeholders in construction projects. As a result, empirical studies are few and conflicting because accessing data on transaction costs is problematic, and the interpretation of the data is difficult. The purpose of this paper is to analyze the transaction costs borne by the owner in a construction project from the perspective of transaction cost economics and construction project characteristics.

A questionnaire survey was administered to construction owners. The factors that impact transaction costs were analyzed in the context of human-related issues (the owner's and the contractor's positions in the transaction), and environment-related issues (the transaction environment, and project management efficiency). Statistical analyses were conducted to compare the transaction costs incurred in the pre- vs post-contract phases of a project relative to the private vs public sector, different project delivery systems, different procurement methods, and different types of contracts.

The owners surveyed believe that transaction costs may be reduced if the owner and the contractor follow some basic guidelines (e.g. experience in similar projects, prompt payment, good relationship with project participants, no irregularities in bidding, and only few material substitutions and claims), if the project is well-run (e.g. technical competency, strong leadership, prompt decision-making, effective communication, and fair/speedy conflict management), and if the transaction environment is favorable (e.g. fair risk allocation, early contractor involvement, and complete design documents). The findings of the survey also indicate that post-contract transaction costs are much higher than pre-contract transaction costs expressed as percent of project value and that transaction costs are affected by the owner (public vs private), the procurement method, the project delivery system, and the type of contract.

The primary contribution that this research makes to the body of knowledge is a better understanding of transaction costs incurred by construction owners in the USA. The highest transaction costs are to be expected in the post-contract phase of public projects awarded on a unit price basis, but can be reduced, hence reducing overall project cost.

This study aims to comprehensively examine the stock market effects of announcements by firms to issue conventional bonds versus Sukuk. In addition, the authors investigate whether the choice of instrument depends on the tax status and government backing of the issuing firm. They split the sample into whole (2000-2015), pre-crisis (2000-2007) and post-crisis (2010-2015) subsamples.

The authors use event study methodology, market model and FTSE Bursa Malaysia EMAS index on 14 different event windows of which five are symmetric and nine are asymmetric. Further, parametric and distribution-free tests are used to investigate the difference of cumulative abnormal returns when using the two instruments (Sukuk and conventional bonds). For the choice of issuing conventional bonds or Sukuk, Heckman procedure is employed to control for the self-selection of the announcement effects.

The analysis indicates only insignificant difference in reaction to Sukuk and conventional bond issuances for the overall period and pre-crisis period. However, and importantly, they find strong evidence supporting the Malaysian stock abnormal return reaction to Sukuk compared to conventional bond issuances after the global financial crisis. Interestingly, they find that tax incentives and government backing are significant determinants in issuing Sukuk over conventional bonds. Such evidence is confirmed when using a wide range of robustness checks including four different market indices and both parametric and non-parametric tests.

The empirical analysis is subject to limitations. First, the sample is limited to Sukuk issues domiciled in Malaysia. Second, given that Sukuk are collateralized whereas conventional bonds are not, it would only seem logical for the former to be issued by riskier firms whereas the latter would be issued by stronger firms with stable cash flows. The future research can explore this issue some more. Finally, comparing Sukuk with other similar ethical sources of traded capital may provide insights into the globalization of such economic, trade and financial reforms in and outside Malaysia.

To the author’s knowledge, no research has been conducted studying the differential and conflicting results to announcement of Sukuk issuance in the literature, nor the stock market effects of announcements to issue Sukuk over the pre-crisis (2000-2007) and post-crisis (2010-2015) periods. Thus, the study attempts to assess previous findings and contribute additional evidence that investigates the issue in rich setting.

The study aims to provide a quick-and-robust multifactorial screening technique for early detection of statistically significant effects that could influence a product's life-time performance.

The proposed method takes advantage of saturated fractional factorial designs for organizing the lifetime dataset collection process. Small censored lifetime data are fitted to the Kaplan–Meier model. Low-percentile lifetime behavior that is derived from the fitted model is used to screen for strong effects. A robust surrogate profiler is employed to furnish the predictions.

The methodology is tested on a difficult published case study that involves the eleven-factor screening of an industrial-grade thermostat. The tested thermostat units are use-rate accelerated to expedite the information collection process. The solution that is provided by this new method suggests as many as two active effects at the first decile of the data which improves over a solution provided from more classical methods.

To benchmark the predicted solution with other competing approaches, the results showcase the critical first decile part of the dataset. Moreover, prediction capability is demonstrated for the use-rate acceleration condition.

The technique might be applicable to projects where the early reliability improvement is studied for complex industrial products.

The proposed methodology offers a range of features that aim to make the product reliability profiling process faster and more robust while managing to be less susceptible to assumptions often encountered in classical multi-parameter treatments.

The Orange River is one of the largest river basins in southern Africa. Since it plays a crucial role in the region's ecology and economy, it is important to estimate future developments in its hydrology. A necessary means to this end are climate projections. This paper seeks to address this issue.

In this work the authors present projections obtained by two complementary methods; they use a Statistical Analogue Re‐sampling Scheme (STARS) and a dynamical regional climate model (CCLM – COSMO in Climate Mode). In order to determine the viability of these methods, the authors perform cross‐validations for the years 1976‐2000.

CCLM shows good performance regarding the 2 m temperature but the reproduction of precipitation is rather poor. STARS, on the other hand, produces very good results for both variables. The climate projections of both models show a considerable temperature increase for the future (2036‐2060, SRES A1B scenario), especially in the inland of the simulation area. However, while CCLM projects a general decrease in precipitation, STARS indicates a strong precipitation decrease in the already dry western part of the region and a moderate decrease resp. no change in the east during the rain season.

For the first time the statistical approach used gridded data as its input. Therefore, it was possible to apply complementary methods in order to generate the climate projections and to compare them.

The purpose of this paper is to examine current practices of logistics cost management (LCM) in Mainland China and identify factors impacting on the effectiveness of LCM.

The questionnaire‐based survey is conducted in Mainland China. To analyze the status quo of LCM in Mainland China, the paper takes two nonparametric tests, Mann‐Whitney U‐test and Kruskal‐Wallis one‐way analysis of variance to compare the difference between firms with and without attaching importance to LCM.

The difficulties of LCM in China is as follows: first, there is a lack of effective cost measurement tools and analyses as well as reporting systems, especially in terms of distributors. Second, it is very critical to organize intra‐organizational cross‐functional teams and inter‐organizational collaboration based on business processes to promote information integrating instead of blindly investing on information technology application. Third, professional logistics managers are in short supply, even among logistics service providers.

First, although the sample covers some industries, the generalization of the conclusion is still limited due to sample size. In future research, more industries should be covered to test the hypotheses proposed. Second, this paper just analyzes the status quo of Chinese company LCM. Future studies are encouraged to deeply explore internal and external operational management factors impacting on LCM.

This paper is a very insightful source of information about LCM in Mainland China for logistics managers and policy makers. This paper provides logistics managers with insight so as to improve their performance. There are also suggestions for government and educational institutions to provide more resources to develop and offer more logistics courses and training programs to fulfill the needs of the logistics industry. The paper sets up a basis for research on LCM in China.

Despite the importance of LCM in Mainland China, the extant literatures scarcely have a sound analysis. Theoretically, this paper extends theories of LCM in China and identifies main issues concerning LCM. This paper is an exploratory study to figure out an effective LCM approach in China.
