Purpose This paper aims to prepare an associative thickener base on two polyacrylate-based copolymers, which can be used for digital printing of nylon carpet with enhanced performance. Design/methodology/approach An associative thickener was prepared by compounding two polyacrylate-based copolymers, cationic starch and polyacrylic acid; and mediated by polyethylene glycol and polyacrylamide crosslinker. The formulation of the associative thickener was optimized by using the orthogonal array testing strategy. The stability of the associative thickener was investigated by measuring effects of temperature, electrolytes, storage time and auxiliaries on viscosity. The associative thickener was compared with a commercial thickener by evaluating their performance in digital printing of nylon carpet. Findings The associative thickener provided same color strength and fastness in the printing of nylon carpet as the commercial one, but was more easily washed off for a better hand feeling of the printed carpet. Practical implications The prepared associative thickener can be applied for digital printing of nylon carpet. Originality/value The associative thickener can be facilely prepared from commercially available chemicals and suitable for digital printing of nylon carpet.

Purpose The purpose of this paper is to predict the concrete pouring production rate by considering both construction and supply parameters, and by using a more stable learning method. Design/methodology/approach Unlike similar approaches, this paper considers not only construction site parameters, but also supply chain parameters. Machine learner fusion-regression (MLF-R) is used to predict the production rate of concrete pouring tasks. Findings MLF-R is used on a field database including 2,600 deliveries to 507 different locations. The proposed data set and the results are compared with ANN-Gaussian, ANN-Sigmoid and Adaboost.R2 (ANN-Gaussian). The results show better performance of MLF-R obtaining the least root mean square error (RMSE) compared with other methods. Moreover, the RMSEs derived from the predictions by MLF-R in some trials had the least standard deviation, indicating the stability of this approach among similar used approaches. Practical implications The size of the database used in this study is much larger than the size of databases used in previous studies. It helps authors draw their conclusions more confidently and introduce more generalised models that can be used in the ready-mixed concrete industry. Originality/value Introducing a more stable learning method for predicting the concrete pouring production rate helps not only construction parameters, but also traffic and supply chain parameters.

PurposeWithout the stability of tenure, adjunct faculty have few barriers to leave their position. The purpose of this article is to understand the variables that predict commitment among adjunct instructors.Design/methodology/approachThis paper statistically analyzed data from a survey completed by adjunct instructors at two 4-year universities. The survey included scales on commitment, satisfaction, investments, alternatives and the psychological concepts of grit and self-efficacy. In addition, a qualitative analysis was conducted on supplemental open-ended questions that allowed participants to describe the basis of their commitment.FindingsSatisfaction and investments were the main predictors of commitment and those together accounted for just over 50 percent of the variance. Grit and self-efficacy did not correlate with commitment, but did correlate with satisfaction and investments.Practical implicationsGiven the predictive power of satisfaction to explain commitment, understanding the specific rewards and costs experienced by this population can give administrators ideas for making the part-time position more appealing. Similarly, given the predictive power of investments, administrators might consider identifying avenues for adjunct faculty to contribute to the department and university in a meaningful and rewarding way.Originality/valueUniversities are increasingly dependent on adjunct instructors, so it is worthwhile to understand the experience of such faculty. This is best done through research, rather than relying on assumptions, stereotype or anecdotes.

Purpose This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies. Design/methodology/approach This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings Building a regional rather than a global supply chain can help firms guard against the damaging impact of the bullwhip effect and increase the stability of their supply chain. The possibility of better communication, greater flexibility, and ability to respond more quickly are factors that can appease the bullwhip severity. The benefits of a regional supply chain increase further in times of economic certainty, when the risk to global supply chains intensifies. Originality/value The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

Purpose The framework of the International Integrated Reporting Council (IIRC) is principles-based and does not provide specific key performance indicators (KPIs) for integrated thinking and reporting. Therefore, the purpose of this paper is to propose KPIs for integrated reporting which decipher a firm’s sustainability through empirical analysis. Design/methodology/approach As a proxy of firms’ sustainability, the authors focus on firms that have survived for more than 100 years and that have already achieved sustainability, and analyze these firms to reveal the financial features that distinguish sustainable firms from the other firms. Findings The study found two distinguishing facts: the value added that is distributed to stakeholders other than shareholders is significantly larger, and the stability of profitability and the profitability itself are significantly higher in sustainable firms. Practical implications The study proposes a value-added distribution and the stability of profitability as sustainability KPIs for integrated reporting. Originality/value First, this study provides the first evidence that value added distribution and the stability of profitability distinguish a firm’s sustainability. Second, it provides a new perspective in the search for sustainability KPIs. Third, as the empirical data consist of all listed firms in 136 countries, the results should be robust and general.

Purpose The purpose of this paper is to develop mathematical tools that are reliable and easily implementable in computer codes, which address the determination of the outriggers reaction of mobile cranes and the monitoring of the actual stability margin available during lift operations. Design/methodology/approach An algorithm that determines the load transmitted to the ground by a mobile crane with four outriggers has been developed. Static theory of rigid body is adopted for the development of the algorithm and the static indeterminancy, due to the presence of more than three outriggers, is eluded through the adoption of specific hypotheses. An analysis of crane stability is also performed, and a method to monitor the actual stability behavior during lift operations is suggested. Findings A case study is proposed to test the algorithm and outcomes show a good matching with the actual outriggers reaction measured during a test conduct in situ. Two indices are introduced as a measure of the stability margin. Research limitations/implications The method developed accounts only for gravitational forces statically applied. Future works should be addressed to extend the model to the effect of wind and inertial forces. Practical implications This paper supplies a reliable tool to assess, in the design phase of a lifting operation, the compliance between bearing capacity of the ground and loads transmitted by outriggers. The method proposed for the analysis of the stability behavior is suitable for the development of an anti-upset device. Originality/value This study contributes to efforts to increase safety during lifting operations with mobile cranes. The method proposed is applicable to cranes with any geometry of the outriggers pattern and is extensible to a number of outriggers greater than four. Furthermore, the evaluation of the measure in real time of the stability margin, is not affected by the data entered by the crane’s operator with the consequence that human factor does not affect this measure.

Purpose Given the recent peaceful turnover of power through a highly participatory democratic election, now is a good time to consider Taiwan and its political development. Design/methodology/approach The author reviews how, over two decades Taiwan has undergone a remarkably peaceful transition from what was essentially an authoritarian, one-party dictatorship by the KMT to a vibrant multiparty democracy, a sharp contrast to what has occurred during the same period in China. Findings When the traditional ruling party of a country–like the Kuomintang in Taiwan– finds itself completely out of power and wandering in the wilderness, yet still manages to conduct itself with grace and dignity, and in so doing, allows the country to prosper – that affirms the stability and progressive potential of the country’s politics. Practical implications Not only has Taiwan’s economy seen a sustained period of fast growth over multiple decades, but the economy has grown without seeing a substantial uptick in economic inequality, a feat many developed nations have failed to achieve. Originality/value Taiwan’s two decades of political stability makes is an attractive commercial partner.

Purpose – The purpose of this paper is to investigate the simultaneous effect of perceived value, image, perceived ease of use and perceived usefulness on passengers’ satisfaction. Design/methodology/approach – The empirical data were collected through survey. The respondents of the survey are 292 public transport passengers in Jakarta, Indonesia. Multiple regressions analysis was performed to test the conceptual model and the proposed hypotheses. Findings – The findings showed that public transport passengers’ satisfaction is influenced by perceived value, perceived usefulness and image while perceived ease of use does not affect public transport passengers’ satisfaction. Research limitations/implications – The authors performed the survey only at Jakarta using convenience sampling method. Hence, the research results may not be generalized to other contexts. Given this, in order to test the stability of the findings in other contexts, a replication research is important to be performed in the future. Practical implications – Public transport service managers need to pay attention to perceived value, perceived usefulness and image in order to ensure public transport passengers’ satisfaction. Originality/value – This study is believed to be the first to develop and test public transport passengers’ satisfaction model that integrated perceived value, image, perceived ease of use and perceived usefulness.

Purpose The purpose of this study is to explain the effects of screen printing parameters on the quantity of ink deposited and the print quality in the context of printing of functional inks. Both these aspects of printing are crucial in the case of conventional and functional printing. This is because, in the case of conventional printing, the quantity of ink deposit affects the color strength while in the case of functional printing, it directly affects the resulting functionality of the ink layer. Design/methodology/approach In this work, an automatic lab-scale screen printer was used to print functional inks on a paper board substrate. The printing parameters, i.e. printing pressure and squeegee angle were altered and the resulting effects on the quantity of ink that was deposited were recorded. The quantity of ink deposit was related to its surface resistivity. In addition, the quality of the print was also assessed by examining the design registration quality. Findings The authors found that altering the squeegee angle has a significant effect on the properties of the resulting ink deposit. More importantly, the authors found that the deflection in the rubber blade squeegee was greatly dependent on the initial angle of the squeegee at the start of the printing stroke. For each set value of the squeegee angle that was considered, the actual angle during printing was recorded and used in the analysis. A printing pressure of three bars and squeegee angle of 20° resulted in the maximum weight of ink deposit with a correspondingly lowest surface resistivity. Practical implications This study is envisaged to have considerable practical implications in the rapidly growing field of functional printing of flexible substrates including, but not limited to, textiles. This is because, the study provides an insight into the effects of printing parameters on the characteristics of a functional ink deposit. Originality/value Screen printing of flexible substrates is a well-developed and arguably the most widely used printing technique, particularly for textiles. Numerous studies report on the analysis of various aspects of screen printing. However, to the best of the knowledge, the effects of printing parameters on the characteristics of functional inks, such as electrically conductive inks, have not been studied in this manner.

Purpose This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies. Design/methodology/approach This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings In some instances, business networks can be seen to stifle and hinder expansion and the adoption of new technologies. The interlinking of numerous actors and authors within a network means that competing agendas often cancel each other out. Organizations in a business network are unable to act according to their own best interests, instead having to react to the changes of all the other organizations in the network. This constant act of compromise can severely limit the potential of an organization and a business network. But the stability of a business network can be used to an advantage if the associated organizations embrace disalignment actions and the friction technological commercialization causes. By allowing actors to (re)negotiate their roles within a network, the organizations can successfully adopt new technologies and maintain a competitive edge. Mattila (2017) uses the development and implementation of intelligent paper in Finland, as an example of how a business network can use the friction caused by disalignment to succeed in a highly competitive global market. Practical implications The paper provides strategic insights and practical thinking that have influenced some of the world’s leading organizations. Originality/value The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

Purpose – The purpose of this paper is to demonstrate the implications of power imbalance and over-emphasis on commercial logic on the structure and governance of Scottish football. Design/methodology/approach – An in-depth analysis of secondary sources is used to identify the logics at play in Scottish football and to explore implications of the liquidation of Rangers for the structure of the game. Findings – Over-emphasis on commercial logic has led to power being concentrated in two clubs, Celtic and Rangers, and to other clubs and the league itself becoming financially dependent on those clubs. The collapse of Rangers thus threatened the stability of other clubs and the league. The case highlights the challenge of reconciling competing logics and the role played by previously peripheral actors in bringing about change in the field. Research limitations/implications – The on-going nature of the case, related investigations and legal process meant that it was not possible to supplement the secondary source material with primary evidence. Practical implications – It demonstrates the multi-faceted nature of elite contemporary football and of the challenges faced by leagues and governing bodies in accommodating logics and multiple stakeholder interests. It also highlights the need for more effective financial regulation of corporate football clubs and their officials and emphasises the importance of inclusive stakeholder governance. Originality/value – It highlights the risks inherent in football business in small markets dominated by one or a few clubs. It highlights the role that previously peripheral actors can play in bringing about change within a field.
