Purpose This paper aims to propose a novel approach which integrates collocations and domain concepts for Chinese cosmetic word of mouth (WOM) sentiment classification. Most sentiment analysis works by collecting sentiment scores from each unigram or bigram. However, not every unigram or bigram in a WOM document contains sentiments. Chinese collocations consist of the main sentiments of WOM. This paper reduces the complexity of the document dimensionality and makes an improvement for sentiment classification. Design/methodology/approach This paper builds two contextual lexicons for feature words and sentiment words, respectively. Based on these contextual lexicons, this paper uses the techniques of associated rules and mutual information to build possible Chinese collocation sets. This paper applies preference vector modelling as the vector representation approach to catch the relationship between Chinese collocations and their associated concepts. Findings This paper compares the proposed preference vector models with benchmarks, using three classification techniques (i.e. support vector machine, J48 decision tree and multilayer perceptron). According to the experimental results, the proposed models outperform all benchmarks evaluated by the criterion of accuracy. Originality/value This paper focuses on Chinese collocations and proposes a novel research approach for sentiment classification. The Chinese collocations used in this paper are adaptable to the content and domains. Finally, this paper integrates collocations with the preference vector modelling approach, which not only achieves a better sentiment classification performance for Chinese WOM documents but also avoids the curse of dimensionality.

The Relationship

Purpose This paper studies buyer–supplier relationships (BSRs) by taking a routine-based approach and develops a taxonomy of BSRs. Recent advances in the BSR literature have shown that firms implement a host of diverse routines, called integrative practices, with their supply chain partners. Relationships differ based on what integrative practices are present in them. This paper aims to develop a taxonomy of supply chain relationships based on integrative practices measured at the relationship level. Design/methodology/approach The authors use survey data collected from North American manufacturers to establish the measurement properties of new relationship level constructs that represent different aspects of integration. Cluster analysis is used with these new constructs to develop a taxonomy of supply chain relationships. Regression and bootstrapping techniques are used to establish the predictive validity and stability of the taxonomy. Findings The results show four distinct types of relationships. On comparison, the authors find salient differences between their results and past classifications. As a result of taking a routine-based multidimensional view of integration, the authors find two types of relationships that have not been discovered by past taxonomies. Originality/value The new relationship level constructs will allow academics to have greater precision in their research questions on BSRs, as not all aspects of integration behave in the same manner. The four types of relationships identified by this study provide a useful framework to manage supply chain relationships for practitioners.

Purpose This research investigates the perceived collaboration between public, private, and volunteer organisations during maritime crisis work, with an emphasis on learning and collaboration. The purpose of this paper is to investigate participants’ perceived collaboration training in relation to learning and usefulness. Design/methodology/approach The exercise studied in this research was run in the far North in Norway. It was estimated by the participants to be Europe’s most extensive exercise in 2016. Mixed methods research approach was applied, i.e. on-site observations, photos and interviews were conducted during the exercise. After the exercise, an online survey was distributed to emergency personnel holding different positions in conjunction with this exercise. Findings As reported, the exercise contributed to new insights on the relationship between collaboration and learning. The study showed that collaborative elements in exercises contribute to perceived learning (R=0.86, R2=0.74), and that learning in turn had a perceived beneficial effect on actual emergency work (R=0.79, R2=0.62). Research limitations/implications The possible research implications from this study include more focus on collaboration and new training schemes that could increase learning and usefulness. Practical implications Collaboration between actors seemed to suffer from the size of the exercise. A smaller exercise, less dependency on predetermined scripts, and more receptivity towards improvisation could improve collaboration. Social implications Increased awareness on the outcomes of collaboration exercise might increase their learning and usefulness, providing societies with improved rescue services. Originality/value This research implies that increased perceived collaboration has an effect on learning and usefulness in maritime exercises.

The Relationship

Purpose – This paper uses a number of current examples from a variety of industries both regional and global, to explore the relationship between business longevity, environment, and adaptiveness to argue that only adaptive responses contingent on a proper classification of external circumstance will result in productive efficacy for the business. The paper aims to discuss these issues. Design/methodology/approach – There is compelling evidence that businesses have limited life spans. Management and economic theories of creative destruction, argue that this is salutary for markets and economies. Yet as a counterpoint there are significant benefits to business longevity. Such longevity, however, is predicated on the business's dimensionalised understanding of its task and contextual environment and its deployment of an adaptive response contingent on such understanding. Findings – It is mandatory in prevailing times that adaptive responses ensure that the overall business has external fit and alignment with its environment and internal congruence and consistency between organisational subsystems and their internal subenvironments. Originality/value – The calculus of limited and unpredictable business life spans is justified by theories of creative destruction and hypercompetition. Yet there are intrinsic and extrinsic advantages to business longevity. A causative flow is proffered that predicates business longevity on its ability to; first, classify its prevailing environment, and thereafter deploy contingent adaptive responses for productive efficacy.

Purpose In 3D additive screen printing with constant snap-off, the inhomogeneous screen counterforce will influence the printing force and reduce the printing quality. The purpose of this paper is to study the relationship between scraper position, snap-off and screen counterforce and develop a variable snap-off curve for 3D additive screen printing to improve the printing quality. Design/methodology/approach An experiment was carried out; genetic algorithm (GA) optimization theoretical model, backpropagation neural network regression model and least square support vector machine regression model were established to study the relationship between scraper position, snap-off and screen counterforce. The absolute errors of counterforce of three models with the experiment results were less than 1.5 N, which was tolerated and the three models were considered valid. The comparison results showed that GA optimization theoretical model performed best. Findings The results suggest that GA optimization theoretical model performed best to represent the relationship, and it was used to develop a variable snap-off curve. With the variable snap-off curve in 3D additive screen printing, the inhomogeneous screen counterforce was weakened and the printing quality was improved. Originality/value In printing production, the variable snap-off curve in 3D additive screen printing helps improve the printing quality; this study is of prime importance to the 3D additive screen printing.

Purpose The purpose of this study is to develop and empirically test a model investigating the relationship between conflict with private label (PL) suppliers and retailers’ PL performance. The study also examines differences in the relationship based on two PL types, namely, price-oriented and differentiation-oriented PLs. Design/methodology/approach Hypotheses were tested using structural equation modeling and data obtained from a survey of general merchandise managers in 190 supermarket chains in Japan. Findings The results indicate that conflict with PL suppliers can have negative effects on retailers’ PL performance. Moreover, the use of price-oriented PLs leads to higher levels of conflict with PL suppliers than the use of differentiation-oriented PLs. Practical implications This study offers managerial insights into the importance of sophisticated conflict management in relation to PL suppliers and the efficacy of premium PLs, which may cost less in terms of conflict management than price-oriented PLs. Originality/value Considering the influence of conflict with suppliers on retailers’ PL performance, this study suggests a novel approach to examining conflict between PL suppliers and retailers by classifying PLs into two types, namely, price-oriented and differentiation-oriented PLs.

Purpose A methodology that combined ethnographies, including the ethnography of performance with narrative inquiry was used in a research project investigating the assessment of senior secondary Drama performance in Australia. The paper aims to discuss this issue. Design/methodology/approach After a temporal change in the research approach, it was decided that the research method needed to capture the Drama performance assessment phenomenon as it was lived and experienced. Findings As a result, methodological choices shifted from procedural documentation and document analysis to ethnographic observations that were able to capture the more nuanced aspects of the relationship between Drama performance and assessment, embracing tacit learning, agendas, cultures, experiences and understandings. Originality/value This paper reflects on the methodological dilemmas and choices made when studying artistic and aesthetic texts in the classroom, and poses considerations for future researchers conducting inquiries in aesthetically rich learning environments.

Purpose – Few empirical studies have probed the effects of culture on the standardization/adaptation decision in the context of controversial products. This study aims to investigate the relationship between sociosexuality and the adaptation decision for editorial images and advertisements in Playboy magazine through content analysis. Design/methodology/approach – This study is a qualitative research using content analysis as the research approach. The content analysis is done for Playboy magazines from four culturally diverse countries conducted for this study. Findings – The result shows that editions of the magazine across four culturally diverse countries reveal that sociosexuality is positively correlated to the degree of nudity in photographs and to the usage of advertising for controversial products. Moreover, the paper uses the concept of sociosexuality to gain a better understanding of the empirical discrepancies concerning nudity or sex appeal. Originality/value – This research is an empirical study developed by author to confirm the influence of culture on the standardization/adaptation decision in the context of controversial products. This research is originally developed by author and has not been published before.

Purpose The purpose of this paper is to present an empirical evidence of the impacts of supply chain uncertainty and risk on the logistics performance in the Australian courier industry. This study examines the impacts of supply chain and risk on the logistics performance in the Australian courier industry. Design/methodology/approach This study provides an in-depth analysis of supply chain uncertainty and risk’s impacts on the logistics performance. The structure equation modelling approach is applied to examine the relationship between supply chain uncertainty and risk and logistics performance. Company-side uncertainty and risk, customer-side uncertainty and risk, and environment uncertainty and risk are used to measure the impacts of supply chain uncertainty and risk on the industry. This paper gives attention to the supply chain uncertainty and risk in the industry. Findings The results indicate that supply chain uncertainty and risk have negative impacts on logistics performance. Moreover, the greatest impact of supply chain uncertainty and risk was from outside company in the Australian courier industry. Research limitations/implications The study focuses on the Australian courier industry, this may limit the implications of findings in different industries. However, the research models may be examined and validated in the different context. Practical implications The results may provide directions in the implementation of strategies to manage supply chain uncertainty and risk and improve logistics performance. The findings may enlighten both academics and practitioners to understand and pay attention to the supply chain uncertainty and risk in the courier industry. Originality/value There is an argument whether the impacts of supply chain uncertainty and risk are positive or negative in previous studies. In addition, there are very few studies on courier industry. This study clarifies the impacts of supply chain uncertainty and risk on the logistics performance in the courier industry.

Purpose In an effort to encourage more probing studies of organizational learning and the learning organization (OL/LO), this paper aims to highlight the value of extended periods of fieldwork and suggest priorities for future fieldwork-based research into OL/LO. Design/methodology/approach The paper draws on the author’s research and consultancies in the OL/LO field and on systematic reviews of OL/LO literature. Findings Evidence is presented to justify the following four priorities for future fieldwork-based studies of OL/LO: to obtain trustworthy data, to bring the role of time and place into sharp focus, to explore the relationship between organizational learning and interests and to identify strategies for improving organizational learning in particular contexts. Originality/value The paper suggests priorities for a research approach that is not often used to study organizational learning and the learning organization, namely, to undertake extended periods of fieldwork in individual organizations or parts of organizations, gathering trustworthy data and interpreting it with the help of extant OL/LO theory.

Purpose The purpose of this paper is to adopt an organisational network perspective to examine the structural properties underpinning the design and governance of multi-agency fusion centres and related environments, focussing particularly on how they are formed and internally managed. Design/methodology/approach The authors conducted several focus groups and follow-up interviews with executive and operational members of Australia’s principal fusion centres and related environments. Findings The authors argue that in order to understand the internal dynamics of fusion centres, and the ways in which they form and function, the analysis of interrelationships between partners and potential partners is critical. The authors have demonstrated that a network model can assist in this type of analysis. For example, hub-and-spoke network structures appear to be a particularly effective solution to the centralisation-density trade-off for such inter-agency networks. Originality/value The authors use a novel approach that combines a goal-oriented network framework with the existing literature on fusion centres to synthesise key features of the network structure of fusion centres and associated processes of information sharing.
