One popular method to assess discriminant validity in structural equation modeling is the heterotrait-monotrait ratio of correlations (HTMT). However, the HTMT assumes tau-equivalent measurement models, which are unlikely to hold for most empirical studies. To relax this assumption, the authors modify the original HTMT and introduce a new consistent measure for congeneric measurement models: the HTMT2.

The HTMT2 is designed in analogy to the HTMT but relies on the geometric mean instead of the arithmetic mean. A Monte Carlo simulation compares the performance of the HTMT and the HTMT2. In the simulation, several design factors are varied such as loading patterns, sample sizes and inter-construct correlations in order to compare the estimation bias of the two criteria.

The HTMT2 provides less biased estimations of the correlations among the latent variables compared to the HTMT, in particular if indicators loading patterns are heterogeneous. Consequently, the HTMT2 should be preferred over the HTMT to assess discriminant validity in case of congeneric measurement models.

However, the HTMT2 can only be determined if all correlations between involved observable variables are positive.

This paper introduces the HTMT2 as an improved version of the traditional HTMT. Compared to other approaches assessing discriminant validity, the HTMT2 provides two advantages: (1) the ease of its computation, since HTMT2 is only based on the indicator correlations, and (2) the relaxed assumption of tau-equivalence. The authors highly recommend the HTMT2 criterion over the traditional HTMT for assessing discriminant validity in empirical studies.

The purpose of this paper is to provide a systematic overview with guidelines how to use partial least squares (PLS) path modeling in longitudinal studies. Practical examples from a study of the acceptance of battery electric vehicles (BEVs) in corporate fleets are used for demonstration purposes.

In this study, data at three points in time were collected: before the initial use of a BEV, after three and after six months of extensive usage of BEVs.

Three different models are identified depending on the research objective and on the data basis. Multigroup analyses are suggested to test the difference between the path coefficients of latent variables at different points in time. Limitations for the use of repeated cross-sectional data have to be observed.

Academics and practitioners will benefit from this paper by receiving an overview of the different PLS path models in longitudinal studies. A decision-tree enables them to make a choice regarding the most appropriate model and suggests a sequence of complementary analyses. So far, there is a lack of a tutorial type paper delivering such guidance.

Much research has been dedicated to the screening of new product ideas. Far less is known, however, about how to select the most promising new service ideas. Moreover, the specific characteristics of business services are rarely taken into account. This paper aims to investigate this issue.

Based on an extensive literature review and on a case study in the business‐to‐business information technology industry, this paper therefore develops a screening method with which to assess and select new business service ideas.

The study surprisingly reveals that the customers' view is rarely included into the valuation of new service ideas in management practice, although customer involvement is largely claimed in the literature. The supposition is that customer involvement is seen as difficult and costly in practice.

The paper proposes an effective and manageable tool to assess new business service ideas that also allows for easy involvement of customers into the screening process.

To demonstrate that, at its core, Marx’s critical theory is not a critique of a mode of class exploitation that distorts modernity, undertaken from a standpoint that affirms labor, but rather one that uncovers and analyzes a unique form of social mediation and domination that structures modernity itself as a historically specific form of social life.

Critical reconstruction, interpretation, and application of Marx’s critique of political economy as developed in the Grundrisse and Capital, to the massive global transformations of the past four decades.

Marx’s critical analysis is well-suited to function as the foundation for a theory that systematically illuminates modern society in the 21st century. It is more conducive to grasping the contemporary world than traditional Marxism or most versions of post-Marxism.

The historical transformations of the past century suggest the central significance of a critique of capitalism for an adequate critical theory today. Such a critique must be capable of grasping the core of a social formation that is generative of a peculiar dynamic of identity and non-identity, of pointing beyond itself while reasserting itself. It indicates that the realization of the possibility of the abolition of proletarian labor is a necessary response to a deep structural crisis of capitalism.

Circular economy (CE), as a new economic paradigm, has gained traction in recent years. Cities' role in driving CE forward has been perceived as being increasingly important to achieve sustainable development (SD). For this reason, there is an urgency to understand what a circular city is and how it might be composed. This research explores the ways in which the city-state of Singapore is transitioning to a CE.

A systematic literature review on CE and cities was carried out using a bibliometric review and a snowballing technique. This review was performed on academic and on non-academic papers.

This research has confirmed the lack of robust circular cities case studies. As Singapore has already begun its journey towards circularity, this article examines its current efforts and offers recommendations in the design and implementation of CE policies that may be valuable not just for Singapore but also for high-density and rapidly expanding cities around the world that require a new development pathway to emulate.

This manuscript is the first detailed, independent and comprehensive review of Singapore's approach to CE.

This paper aims to explore the experience of living with scars from self-injury; how people who self-injure (SI) make meaning of their scars and how these scars are a part of the identity construction process.

It is observed that 60 entries, from 25 online narrative blogs detailing the experience of living with self-injury scars, were analyzed using a contextualized thematic analysis informed by an embodied perspective.

The analysis generated two dominant themes: temporal aspects of identity; and social stigma and scars.

Far-reaching consequences of self-injury scars on the daily lives of people who SI was found. This included a person’s posture, clothing, choices of career, inclusion in family life, leisure activities and relationships; all of which have corollaries in emotional and psychological well-being. Scars were found to be self-narrative with particular salience given to how scars represented healing. Novel findings included the central role scars played in the resistance of self-injury stigma.

This compilation of over 500 United States Government bibliographies is the second annual supplement to BIBLIOGRAPHY OF UNITED STATES GOVERNMENT BIBLIOGRAPHIES 1968–1973 (Pierian Press). Due to the Government Printing Office backlog during 1974, many 1973 and 1974 titles are included in this 1975 Supplement, which should have appeared earlier.

The literature on destructive leadership has largely ignored the perspective of the subordinate, especially in terms of conflict coping mechanisms. This study aims to integrate research on destructive leadership and subordinates’ voice behaviour as a conflict coping mechanism. Drawing on the social exchange, conservation of resources and social identity theories, it argues that destructive leadership negatively affects employees’ voice behaviour and that this relationship is moderated by subordinate personality and organization climate.

The proposed model was tested on a sample of 275 professionals working in the banking and insurance sector in India using a temporal research design with data collected in two phases six months apart. Partial least squares structural equation modelling was used for data analysis.

The results support the main effect relationship between destructive leadership and subordinates’ voice behaviour and the moderation of subordinates’ personality and organizational climate. Temporal analysis indicates that the nature of some relationships changed across the two time periods.

A greater understanding of destructive leader behaviour and resultant coping strategies of subordinates is likely to provide insights for managers facing such situations. The findings of this study will inform the creation of redressal and voice mechanisms in organizations.

This is among the first studies to examine the impact of negative forms of leadership on subordinates’ conflict coping mechanisms using a temporal lag design across two time periods.

The purpose of this paper is to critically examine the existing literature on workplace mindfulness and suggest positive organizational behavior (POB) scholarship as a suitable domain to understand the scientific and secular nature of mindfulness.

This conceptual paper is based on the critical analysis of the literature on POB and contemporary mindfulness at work. This paper highlights the limitations of workplace mindfulness in terms of its research and practice. Then, the limitations of workplace mindfulness are analyzed in relation to POB scholarship to suggest a way forward for research and practice.

The findings imply that contemporary mindfulness meets the inclusion criteria of psychological capital and thus it can be adopted and investigated in the workplace using the POB scholarship.

It suggests implications for research and practice by considering mindfulness as a psychological capital construct in the workplace context.

Mindfulness is an interesting topic for organizational researchers, and many organizations are adopting mindfulness to improve their workplace functioning. In recent years, scholars have highlighted potential ethical issues with the adoption of the spiritual and religious nature of mindfulness for workplace benefits. In this regard, the understanding of the scientific and secular nature of mindfulness is limited in organizational literature. This paper advances the knowledge of the literature on contemporary mindfulness and POB and argues the importance of the inclusion of mindfulness in psychological capital.
