Abstract

Purpose

Toyota had mature lean capabilities when developing its supplier network. This paper aims to explore how companies can develop a Toyota-style supplier network (TSN) while their lean capabilities are still evolving.

Design/methodology/approach

Theoretically, this paper relies on the literature on lean maturity levels and lean supplier network development. Empirically, the paper portrays a Toyota-style initiative, detailing the buyer’s efforts to develop internal lean capabilities concurrently with developing lean in its supplier network. It compares the Network for supplier innovation (NSI) initiative with TSN development regarding activities, organizations and knowledge-sharing routines.

Findings

Unlike the sequential development in the case of Toyota, NSI improved performance and capabilities in the buyer’s supplier network by implementing lean in the firm and its supplier network concurrently. Third-party involvement was the key to the initiative’s success.

Research limitations/implications

The findings are based on an in-depth single-case study which allows theoretical generalization but not statistical generalization. Furthermore, the case study concerns an initiative with Norwegian firms during a financial recession. Future studies should consider these limitations on how firms with evolving lean capabilities can develop a TSN-style supplier network and the importance of involving third parties operating in the role of lean master.

Practical implications

This study suggests what buying firms should consider when designing a TSN initiative, enrolling suppliers and engaging third parties that can take on the role of lean master.

Originality/value

Previous research has focused on how mature lean firms develop lean suppliers and networks. This paper extends this to firms whose lean capabilities are still evolving.

Abstract

Purpose

To develop a method for classifying information sender of web documents, which constitutes an important part of information credibility analysis.

Design/methodology/approach

Machine learning approach was employed. About 2,000 human‐annotated web documents were prepared for training and evaluation. The classification model was based on support vector machine, and the features used for the classification included the title and URL of documents, as well as information of the top page.

Findings

With relatively small set of features, the proposed method achieved over 50 per cent accuracy.

Research limitations/implications

Some of the information sender categories were found to be more difficult to classify. This is due to the subjective nature of the categories, and further refinement of the categories is needed.

Practical implications

When combined with opinion/sentiment analysis techniques, information sender classification allows more profound analysis based on interactions between opinions and senders. Such analysis forms a basis of information credibility analysis.

Originality/value

This study formulated the problem of information sender classification. It proposed a method which achieves moderate performance. It also identified some of the issues related to information sender classification.

Abstract

Purpose

The purpose of this paper is to study the nature and concept of emoticons/emojis. Instead of taking for granted that these user-generated formats are necessarily emotional, we empirically assessed in what extent are they and the specificity of each one. Drawing on congruent mood state, valence core and emotion appraisal theories we expected a compatible statistical association between positive/negative/neutral emotional valence expressions and emoticons of similar valence. The positive emoticons were consistently associated with positive valence posts. Added to that analysis, 21 emotional categories were identified in posts and correlated with eight emoticons.

Design/methodology/approach

Two studies were used to address this question. The first study defined emoticon concept and interpreted their meaning highlighting their communication goals and anticipated effects. The link between emojis and emoticons was also obtained. Some emoticons types present more ambiguity than others. In the second study, three years of real and private (Facebook) posts from 82 adolescents were content analyzed and coded.

Findings

Only the neutral emoticons always matched neutral emotional categories found in the written interaction. Although the emoticon valence and emotional category congruence pattern was the rule, we also detected a combination of different valence emoticons types and emotion categories valence expressions. Apparently the connection between emoticon and emotion are not so obviously straightforward as the literature used to assume. The created objects designed to communicate emotions (emoticons) have their specific corresponding logic with the emotional tone of the message.

Originality/value

Theoretically, we discussed the emotional content of emoticons/emojis. Although this king of signals have an Asian origin and later borrowed from the western countries, their ambiguity and differing specificity have never been analyzed.

Abstract

Although media and research accounts of cyber bullying suggest this misbehavior is localized primarily among middle school students, and that its frequency decreases with age, this chapter presents empirical data showing that cyber bullying occurs with considerable frequency among college students across multiple domains of life, specifically school and work. In Study 1, 28 male and 82 female undergraduate students completed a survey examining their online activities as well as their experiences with cyber bullying. Over 30% of the participants indicated that their first experience with cyber bullying was in college. No gender differences were observed with regard to victimization or perpetration, except with online gaming where males reported a higher rate of victimization than females. With regard to personality differences among victims and perpetrators, victims were lower in agreeableness than non-victims. Study 2 examined the prevalence of cyber bullying among 107 college students at work, as well as the negative outcomes linked to the experience of workplace cyber bullying. Nearly a third of the college student sample reported having been the target of cyber bullying within the past six months. Individuals in jobs in which the Internet is essential and racial minorities reported higher rates of cyber bullying at work. Additionally, cyber bullying was positively linked to several negative emotions, as well as burnout and job search effort. These findings have important implications not only for potential negative outcomes that college students may be facing at school and at work but also for organizational justice issues, as differential treatment at work can lead to lawsuits and other negative work outcomes.

Abstract

Saroma Lake is the largest lagoon in Japan, situated at latitude 44°05′07″ and 44°11′58″ north and longitude 143°40′06″ and 143°58′14″ east (Fig. 3.1). It is located in the northeast of Hokkaido along the Okhotsk sea. The size and circumference of the lake area is around 151km2 and 91km, respectively. The pear-shaped lagoon is around 25.7km long and around 9.5km wide. The lake has semiclosed estuaries with sea mouths between Okhotsk sea and lake. In the lake, two artificial sea mouths have been excavated, where the water exchange can be maintained. These are around 300 and 50m wide. Approximately 90 percent of the total inflow from the sea to the lake passes through the former mouth, which was opened in 1927. The salinity level in Saroma Lake is almost similar to that of the Okhotsk sea due to the active tidal water exchange through the two mouths. An average water depth in Saroma Lake is 14m, approximately 18m deep at the deepest point. The lake receives fresh water from 13 rivers, particularly two principal streams (i.e., River Saromabetsu and Baro), where a large quantity of freshwater and subsequent sediments and nutrients are supplied into the lake.

Abstract

Purpose

Increased evidence for the health benefits of probiotics for health restoration coupled with the consumer's inclination towards a safe, natural and cost-effective substitute for drugs have led application of probiotics as a pharmaceutical agent and are rapidly moving in clinical usage. In this context, this article attempts to highlight the potential of probiotics as a pharmaceutical agent.

Design/methodology/approach

Endeavor has been made to explore the significance of probiotics for the modulation of gut ecology and their action. Potentiality of probiotics for their exploitation as a pharmaceutical agent has also been justified. Limitations of probiotic therapy and the various considerations for probiotic therapy have also been delineated.

Findings

Probiotic organisms influence the physiological and pathological process of the host by modifying the intestinal microbiota, thereby affecting human health. Beneficial effects of probiotics as a pharmaceutical agent seem to be strain and dose dependent and more efficacious with their early introduction. Combination of various probiotics proved to be more efficacious than single strain for exhibiting prophylactic activities.

Research limitations/implications

Reviewed literature indicated that it is difficult to generalize for the beneficial effect of all probiotics for all types of diseases as efficacy of probiotics is strain-dependent and dose-dependent and its clinical application needs long-term investigations.

Practical implications

Clinical trials have displayed that probiotics may alleviate certain disorders or diseases in humans especially those related to gastro-intestinal tract.

Originality/value

Ingestion of fermented dairy products containing probiotic cultures may provide health benefits in certain clinical conditions such as antibiotic-associated diarrhoea, rotavirus-associated diarrhoea, inflammatory bowel disease, inflammatory bowel syndrome, allergenic diseases, cancer, Helicobacter pylori infection and lactose-intolerance. Application of probiotics as a pharmaceutical agent is recommended.

Abstract

Purpose

This study examined the factors impeding the implementation of micro-credentials and accepting it as a credible source of earning professional qualifications and certifications necessary for pursuing higher education or other career goals.

Design/methodology/approach

The factors were identified by reflecting on the recent literature and Internet resources coupled with in-depth brainstorming with experts in the field of micro-credentials including educators, learners and employers. Two ranking methods, namely Preference Ranking for Organization Method for Enrichment Evaluation (PROMETHEE) and multi-objective optimization based on ratio analysis (MOORA), are used together to rank the major challenges.

Findings

The results of this study present that lack of clear definitions, ambiguous course descriptions, lack of accreditation and quality assurance, unclear remuneration policies, lack of coordination between learning hours and learning outcomes, the inadequate volume of learning, and lack of acceptance by individuals and organizations are the top-ranked and the most significant barriers in the implementation of micro-credentials.

Research limitations/implications

The findings can be used by educational institutions, organizations and policymakers to better understand the issues and develop strategies to address them, making micro-credentials a more recognized form of education and qualifications.

Originality/value

The novelty of this study is to identify the primary factors influencing the implementation of micro-credentials from the educators', students' and employers' perspectives and to prioritize those using ranking methods such as PROMETHEE and MOORA.

Abstract

Purpose

Emojis are quickly becoming a popular new language in social media and marketing. The capability to express emotions and make message understanding easier is one of the primary reasons for using emojis. The aim of this research was to determine the influence of perceived usefulness, perceived ease of use, trust, and involvement on customer engagement due to emojis used in digital marketing communications among Generation Z (Gen Z) in South Africa.

Design/methodology/approach

Following the descriptive research approach, quantitative research was used in this study. A questionnaire (self-administered) was utilized to test the effectiveness of using emojis among 1,000 young consumers. Structural equation modeling was used to test the hypotheses.

Findings

The findings of the study yielded positive relationships between the variables, namely between trust and involvement; involvement and the perceived ease of use; involvement and perceived usefulness; perceived ease of use and perceived usefulness; trust and customer engagement; perceived usefulness and customer engagement; involvement and customer engagement; customer engagement and intention to purchase; trust and intention to purchase; and perceived usefulness and intention to purchase.

Practical implications

This study can help organizations in emerging markets use emojis in their digital marketing communications to engage customers and stimulate intention to purchase among young people, especially the Gen Z cohort, who seek organizations and brands that understand and connect with them.

Originality/value

By investigating the effects of emojis in digital marketing communications, this study contributes to the customer-centric process and the literature on emoji usage while also involving a credible digital language when communicating with members of Gen Z. By extending TAM, the findings of this study contribute to the TAM literature by demonstrating that emoji usage in digital marketing communications positively influences various attitudinal associations among Gen Z consumers.

Abstract

Purpose

Anthropomorphized brands have been widely used as marketing communication tools to engage consumers on social media, especially on Twitter. Guided by the social exchange theory (SET) and the dialogic theory, this study aims to investigate how anthropomorphized brands leverage different communication strategies on Twitter and how these strategies are related to consumer engagement.

Design/methodology/approach

Supervised machine learning was used to identify the communication strategies (i.e. message types and dialogic principles) of 125,887 tweets from 21 brand characters. Some statistical analyses (e.g. frequency analysis, Chi-square analysis and Poisson regression analysis) were performed to explore the relationships between communication strategies and consumer engagement (i.e. retweets and replies).

Findings

The majority of anthropomorphized brands’ tweets belonged to the socioemotional category and the most adopted dialogic principles were generation of return visits and conservation of visitors. Consumers engaged more with socioemotional tweets as well as the tweets that adopted the principles of dialogic loop and conservation of visitors. There were clear relationships between message types and dialogic principles in anthropomorphized brands’ tweets, and certain dialogic principles were found to effectively improve consumer engagement with certain message types.

Originality/value

To the best of the authors’ knowledge, this study is the first to investigate the communication strategies of anthropomorphized brand characters on Twitter using computational research methods. It not only provides brand managers a systematic review of how current anthropomorphized brands communicate with consumers on Twitter and what strategies work more effectively to trigger consumer engagement but also contributes to theory building in brand management by integrating the SET and the dialogic theory in brand anthropomorphism research.

Abstract

This chapter is aimed at filling two important gaps in the large literature on high-involvement work system (HIWS). First, the existing literature tends to focus on North America and Western Europe, and detailed information on HIWS outside of the two regions (especially Asia) is still limited. Second, while there is a large body of quantitative evidence, the literature is relatively scant on detailed account of exactly how specific HIWS practices are implemented in the real workplace. This chapter draws on our extensive field research at firms in Japan, the United States, and Korea, and presents real-world examples of HIWS of firms in Japan, Korea, and the United States. Our detailed account of the implementation of HIWS in the three countries points to an intriguing process of transnational diffusion of HIWS. Japanese firms as early experimenters of HIWS posed a challenge to U.S. firms in the global marketplace, resulting in the trans-pacific diffusion of HIWS which is modified to the U.S. corporate culture. Due to its geographical proximity and historical connections to Japan, Korean firms were initially heavily influenced by Japanese HIWS. However, with the rising link to the United States and Europe, Japanese influence appears to have been waning, and interest in U.S. style HIWS and European-style state-mandated works council has risen, suggesting that a hybrid model may be emerging in Korea.
