Advances in information technology have enabled new ways of organizing work and led to a proliferation of what is known as the “gig economy.” While much attention has been paid to how these new organizational designs have upended traditional employee–employer relationships, there has been little consideration of how these changes have impacted the social norms and expectations that govern the relationship between workers and consumers. The purpose of this paper is to consider the social norm of tipping and propose that gig work is associated with a breakdown of tipping norms in part because of workers’ increased autonomy in terms of deciding when and whether to work.

The authors present four studies to support their hypothesis: a survey vignette experiment with workers on Amazon Mechanical Turk (Study 1), an analysis of New York City taxi data (Study 2), a field experiment with restaurant employee food delivery drivers (Study 3) and a field experiment with gig-worker food delivery drivers (Study 4).

In Studies 1 and 2, they find that consumers are less likely to tip when workers have autonomy in deciding whether to complete a task. In Study 3, they find that restaurant delivery employees notice upfront tips (or lack thereof) and alter their service as a result. In contrast, in Study 4, they find that gig-workers who agree to complete a delivery for a fixed amount that includes an upfront tip (or lack thereof) are not responsive to tips. Together, these findings suggest that the gig economy has not only transformed employee-employer relationships, but has also altered the norms and expectations of consumers and workers.

The authors present four different studies that consider the social norm of tipping in the context of gig work. Together, they highlight that perceptions of worker autonomy have driven the decline in tipping norms associated with gig work.

The purpose of this paper is to update and review the concept of warrant in Library and Information Science (LIS) and to introduce the concept of epistemic warrant from philosophy. Epistemic warrant can be used to assess the content of a work; and therefore, it can be a complement to existing warrants, such as literary warrant, in the development of controlled vocabularies. In this proposal, the authors aim to activate a theoretical discussion on warrant in order to revise and improve the validity of the concept of warrant from the user and classifier context to the classificationist context.

The authors have conducted an extensive literary review and close reading of the concept of warrant in LIS and knowledge organization in order to detect the different stances and gaps in which the concept of epistemic warrant might apply. The authors adopted an epistemological approach, in the vein of some of the previous commenters on warrant, such as Hope Olson and Birger Hjørland, and built upon the theoretical framework of different authors working with the concept of warrant outside knowledge organization, such as Alvin Plantinga and Alvin Goldman.

There are some authors and critics in the literature that have voiced for a more epistemological approach to warrant (in opposition to a predominantly ontological approach). In this sense, epistemic warrant would be an epistemological warrant and also a step forward toward pragmatism in a prominently empiricist context such as the justification of the inclusion of terms in a controlled vocabulary. Epistemic warrant can be used to complement literary warrant in the development of controlled vocabularies as well as in the classification of works.

This paper presents an exhaustive update and revision of the concept of warrant, analyzing, systematizing, and reviewing the different warrants discussed in the LIS literary warrant in a critical way. The concept of epistemic warrant for categorizational activities is introduced to the LIS field for the first time. This paper, and the proposal of epistemic warrant, has the potential to contribute to the theoretical and practical discussions on the development of controlled vocabularies and assessment of the content of works.

Collaborative contracting (CC) is the direction that Singapore is venturing into in line with the Construction Industry Transformation Map. For its successful adoption, it is necessary to examine the potential barriers and possible solutions. Therefore, this study aims to explore the current status, major barriers and best solutions for the adoption of CC in the Singapore construction industry.

To achieve these objectives, a comprehensive literature review was carried out and 26 barriers, as well as 21 solutions, were identified. Then a questionnaire was designed to assess the priority of these barriers and solutions. After a pilot study, 165 questionnaires were distributed, and 31 responses were received. And the survey result was validated by post-survey with three industry professionals.

Results revealed that only a small percent of projects adopted CC in Singapore. Seven significant barriers hindering CC implementation were found out. They are “inherent difficulties in changing organizational culture,” “lack of incentives/financial support,” “lack of legislative regulations,” “resistant to change the current way of working,” “seeking for the lowest cost” and “difficulties in converting strategic decisions to operational levels” and “unclear contract terms and objectives.” Also, five best solutions were suggested to overcome the identified barriers.

The findings of this study could enable industry practitioners to be aware of the potential barriers to adopting CC and choose suitable solutions to overcome these barriers. It is also helpful for authorities to come up with effective policies to promote the adoption of CC.

A need for increased attention to the ethical issues of organizational development has been voiced, and unless greater attention is given to ethical issues and problems, the continued potency of organizational development is in danger. While many disciplines train organizational development agents (e.g., psychology, sociology, communication, marketing, business, education), a need for an interdisciplinary code of ethics exists. In addition to proposing an interdisciplinary code of ethics for organizational development agents, the present paper discusses the ethical conduct of data collection, results publication, and change recommendations in the context of organizational development.

The paper discusses the role of measurement and classification in intellectual capital research. Its purpose is to develop an alternative role for measure. The aim is to explore how measurement may be important even if it does not pretend to accurately represent and underlying reality.

The paper is an essay on the difficulties of measuring intellectual capital. It is a conceptual, analytical paper which proposes a new approach to analyzing the roles and effects of measurement in the area of intellectual capital.

The analysis suggests that measurement of intellectual capital is difficult because it is not possible to copy its properties in a number; yet it is necessary because it allows intervention to happen since it develops a wholly new set of dimensions to manage. This dual conclusion both problematic because the search for a definitive measure of the size, value and effects of intellectual capital is impossible, yet it is also comforting because measurement helps develop the actions that can be made in the name of intellectual capital.

The central implication is that research should be explicit about the status of measurement in intellectual capital research since measurement does not primarily represent an underlying reality to be reported by intellectual capital. This directs attention to different purposes of measurement.

This paper explores alternative roles for measurement and suggests that it is necessary to study how measurement is input to management decision making more than a representation of an underlying reality.

The purpose of this paper is to deconstruct the backpacker label by reconstructing it using the historical antecedent of drifting. Following the deconstruction of backpacking’s near past, the author build a clearer conceptual foundation for backpacking’s future.

The study is framed by scenario planning, which demands a critical review of the backpacking and an appreciation of its history in order to understand its future.

Backpacking, ever evolving, remains difficult to articulate and challenges researchers to “keep up” with its complexity and heterogeneity. This paper argues that researchers must learn more about how backpacking “works” by opening a dialogue with its past, before engaging in further research. The paper finds that a poor conceptualisation of backpacking has led to a codification of backpacker criteria.

Backpacking remains a research topic which draws disparate researchers using criteria that produces disparate results and deviations. By understanding its past, researchers will be better placed to explore the emancipatory impulses that drive backpackers today and in the future.

This papers’ value lies in the retrospection process which explores backpacking’s near past so as to “make sense” of present research and present scenarios for it is the immediate future. The paper re-anchors backpacking by investigating the major historical, social and cultural events leading up to its emergence.

Ontology in information studies consists of antinomic conceptions, methodologies, and emphases in both application and philosophizing. A comprehensive understanding of ontology in information studies can be achieved by employing Slavoj Žižek's parallax view which holds that reality is not only best understood by articulating conflicting perspectives on a particular phenomenon, but that given phenomena are fundamentally constrained by incommensurable perspectives that must be acknowledged accordingly. The paper aims to discuss these issues.

Ontology in information studies, including computational ontology development, is analyzed using critical information theory based on Heideggerian, poststructuralist, and anti-postmodern philosophy. The discussion is framed by Žižek's notion of the parallax Real.

A complete understanding of ontology in information studies that does not reduce ontology to a totalizing theory or sequester notions of ontology to conflicting, unrelated discourses, necessarily accepts articulating the alterity between differing ontological views as the means by which one can best allude to what “ontology in information studies really is.”

This paper presents a comprehensive analysis of radically different ontological perspectives on the nature of reality with respect to digital technology.

This paper aims to find the impact of blockchain supply chain on supply chain performance with a mediating role of supplier trust, traceability and transparency.

Data was collected using the purposive sampling technique on a five-point Likert scale from 150 respondents. For data analysis, IBM SPSS and Smart PLS 3.3.7 were used to test the hypotheses by evaluating the structural equation modeling.

The blockchain supply chain found a significant effect on supply chain performance. Moreover, there is a substantial effect of the blockchain supply chain on supply chain performance via mediators, including supplier trust, supply chain traceability and supply chain transparency. Further, the mediation type of all mediators was full mediation in the relationships between blockchain supply chain and supply chain performance.

The research findings are helpful for industrialists, supply chain practitioners and policymakers. The practitioners can adopt blockchain technology to enhance inter-organizational collaboration, develop trust, data visibility and traceability, and critical decisions, ultimately bringing sustainable growth for the firm.

The outcomes of this research enrich the literature and share the impact of one of the most trending technologies in the supply chain perspective. Future research can empirically test the relationship between blockchain and supply chain sustainability.

The purpose of this study is to apply value stream mapping (VSM) in Malaysian pharmaceutical production warehouse. A current and future state value stream map from the raw material receiving end to the production unit was developed to find out waste and unwanted lead time. It was very much essential to cut down the supply chain lead time at the initial phase as the raw material unloading, sorting, temporary storage and dispatch to production were seen contributing to a huge lead time build-up.

The study was initiated with the selection of a product family, construction of the current state map, identification of various wastes and the development of future state map.

The expected outcomes of the study include the quantification of wastes, improvement in value-added percentage and lead time reduction.

The study was carried out in a single pharmaceutical company. The results of the study are deployable and can be functional in similar production organizations. Contrary to common VSMs that capture core production processes, this study provides strong insights that shall help design lean supply chains, especially in the pharmaceutical domain. This paper has also addressed the viability of the lean in the pharmaceutical warehouse and the reduction in lead time to improve demand forecasting, marketing and sales.

The results of this study have indicated that a significant reduction in pharmaceutical warehouse supply chain lead time is possible as a result of the implementation of VSM from the supply chain’s perspective.

The insights from this study help in understanding the pharmaceutical supply chain risks and their outcomes.

The paper reports a real-time study conducted in a warehouse of a pharmaceutical organization. Hence, the contributions are original.

The low success rate of megaprojects stems from the opportunism triggered by uncertainty. Developing trust between participants is an effective means to reduce uncertainty, but this process is inevitably affected by contracts. The purpose of this paper is to examine the impact of uncertainty on participants’ opportunism in megaprojects and the effect of trust on reducing uncertainty. At the same time, the moderating effects of contractual control are tested.

This research classifies trust into competence-based trust and goodwill-based trust and categorizes uncertainty into environmental uncertainty and behavioral uncertainty. Partial least squares structural equation modeling is used to test the hypotheses based on data collected from 172 respondents.

The results show a positive correlation between the two types of uncertainty and opportunism. For the governance of uncertainty, competence-based trust can reduce environmental uncertainty, but it is ineffective for behavioral uncertainty, and goodwill-based trust has a significant effect on both types of uncertainty. The test of moderating effects shows that contractual control strengthens the effect of competence-based trust but weakens the effect of goodwill-based trust, which means that contractual control complements competence-based trust and substitutes for goodwill-based trust.

This research enriches the theory of megaproject management. First, it validates the role of competence-based trust and goodwill-based trust in reducing the different types of uncertainty in megaprojects. Second, this study clarifies the substitution or complementarity between contractual control and different dimensions of trust in the context of high uncertainty, which provides a comprehensive answer to prior research inconsistencies on contractual control and trust.

For practice, this research provides some implications for megaproject management. First, project managers should recognize that the match between trust and project uncertainty is key to the success of megaproject governance. For example, some megaprojects involve many organizations, and there are many difficulties in behavioral supervision and performance appraisal. Therefore, developing goodwill-based trust between participants through positive interactions is an effective means to reduce the behavioral uncertainty of all participants and to curb opportunistic behaviors.

This research validated the role of competence-based trust and goodwill-based trust in reducing the different types of uncertainty in megaprojects. Furthermore, it clarifies the substitution or complementarity between contractual control and different dimensions of trust in the context of high uncertainty, which provides a comprehensive answer to prior research inconsistencies on contractual control and trust.
