The results of this research suggest a new mandate for discriminant validity testing in marketing. Specifically, the authors demonstrate that the AVE-SV comparison (Fornell and Larcker 1981) and HTMT ...ratio (Henseler et al. 2015) with 0.85 cutoff provide the best assessment of discriminant validity and should be the standard for publication in marketing. These conclusions are based on a thorough assessment of the literature and the results of a Monte Carlo simulation. First, based on a content analysis of articles published in seven leading marketing journals from 1996 to 2012, the authors demonstrate that three tests—the constrained phi (Jöreskog 1971), AVE-SV (Fornell and Larcker 1981), and overlapping confidence intervals (Anderson and Gerbing 1988)—are by far most common. Further review reveals that (1) more than 20% of survey-based and over 80% of non-survey-based marketing studies fail to document tests for discriminant validity, (2) there is wide variance across journals and research streams in terms of whether discriminant validity tests are performed, (3) conclusions have already been drawn about the relative stringency of the three most common methods, and (4) the method that is generally perceived to be most generous is being consistently misapplied in a way that erodes its stringency. Second, a Monte Carlo simulation is conducted to assess the relative rigor of the three most common tests, as well as an emerging technique (HTMT). Results reveal that (1) on average, the four discriminant validity testing methods detect violations approximately 50% of the time, (2) the constrained phi and overlapping confidence interval approaches perform very poorly in detecting violations whereas the AVE-SV test and HTMT (with a ratio cutoff of 0.85) methods perform well, and (3) the HTMT
.85
method offers the best balance between high detection and low arbitrary violation (i.e., false positive) rates.
This study introduces the knowledge fusion taxonomy to understand the relationships among traditional marketing analytics (TMA), big data analytics (BDA), and new product success (NPS). With high ...volume and speed of information and knowledge from different stakeholders in the digital economy, the taxonomy aims to help firms build strategy to combine knowledge from both marketing and big data domains. The study suggests that knowledge fusion to improve NPS is not automatic and requires strategic choices to obtain its benefits.
ABSTRACT
We use a catalogue of stellar binaries with wide separations (up to 1 pc) identified by the Gaia satellite to constrain the presence of extended substructure within the Milky Way galaxy. ...Heating of the binaries through repeated encounters with substructure results in a characteristic distribution of binary separations, allowing constraints to be placed independent of the formation mechanism of wide binaries. Across a wide range of subhalo density profiles, we show that subhaloes with masses $\gtrsim 65\, \mathrm{ M}_\odot$ and characteristic length scales similar to the separation of these wide binaries cannot make up 100 per cent of the Galaxy’s dark matter. Constraints weaken for subhaloes with larger length scales and are dependent on their density profiles. For such large subhaloes, higher central densities lead to stronger constraints. Subhaloes with density profiles similar to those expected from cold dark matter must be at least ∼5000 times denser than predicted by simulation to be constrained by the wide binary catalogue.
Fame and celebrity play an ever-increasing role in our culture. However, despite the cultural and economic importance of fame and its gradations, there exists no consensus method for quantifying the ...fame of an individual, or of comparing that of two individuals. We argue that, even if fame is difficult to measure with precision, one may develop useful metrics for fame that correlate well with intuition and that remain reasonably stable over time. Using datasets of recently deceased individuals who were highly renowned, we have evaluated several internet-based methods for quantifying fame. We find that some widely-used internet-derived metrics, such as search engine results, correlate poorly with human subject judgments of fame. However other metrics exist that agree well with human judgments and appear to offer workable, easily accessible measures of fame. Using such a metric we perform a preliminary investigation of the statistical distribution of fame, which has some of the power law character seen in other natural and social phenomena such as landslides and market crashes. In order to demonstrate how such findings can generate quantitative insight into celebrity culture, we assess some folk ideas regarding the frequency distribution and apparent clustering of celebrity deaths.
This article argues for a decolonial response to elite understandings of the Nicaraguan folk play El Gueguense, highlighting a reading of Indigenous survivance. It examines the work from a ...perspective that seeks to eliminate the colonial interpretations placed on it by elite writers, thinkers, and nation builders. Through a review of the literature on the play, associated cultural expressions, and personal experiences and understandings, this article evaluates the work as a product of Indigenous culture and mentality rather than a product of mestizaje or other colonial forces. An analysis of the play's dialogue, imagery, and dances is coupled with an Indigenous Chorotega perspective that demonstrates the spiritual significance of the work, in a discussion that seeks to lift the voices of Indigenous peoples of Pacific, North, and Central Nicaragua.
The construction of heritage is an ongoing process, with numerous voices involved in it. Physical remains of the past frequently—though not always—play a significant role as focal points that ...heritage narratives attach to. As resources, these remains can be used to draw both domestic and foreign tourism, providing economic benefit to states and providing a platform from which heritage narratives may be told. Such narratives can be economically, socially, and politically powerful. They have been previously examined through the authorized heritage discourse, wherein only certain ‘pasts’ are explored, or as heritage brands. In a world of change in society and in tourism, the authority of archaeologist/historian/scholar, governing bodies, tourism agencies, passionate ‘non-specialists’, and multiple publics over heritages is one of contestation. Each is a weaver of heritage. This article examines the creation of archaeological open-air museums (AOAMs) as renewable resources for tourism within a fragmenting market. It explores the authorities and threads of heritage that result in different capacities to actively address visitor perceptions of the ‘past’ and present they are touring. This paper concludes with viewing the use of an AOAM as a location of contestation, as any other heritage property can become, though one more malleable to the changing needs of heritage weavers due to its existence in conflict with understandings of linear time.
The aim of this study is to automatically analyze, characterize and classify physical performance and body composition data of a cohort of Mexican community-dwelling older adults. Self-organizing ...maps (SOM) were used to identify similar profiles in 562 older adults living in Mexico City that participated in this study. Data regarding demographics, geriatric syndromes, comorbidities, physical performance, and body composition were obtained. The sample was divided by sex, and the multidimensional analysis included age, gait speed over height, grip strength over body mass index, one-legged stance, lean appendicular mass percentage, and fat percentage. Using the SOM neural network, seven profile types for older men and women were identified. This analysis provided maps depicting a set of clusters qualitatively characterizing groups of older adults that share similar profiles of body composition and physical performance. The SOM neural network proved to be a useful tool for analyzing multidimensional health care data and facilitating its interpretability. It provided a visual representation of the non-linear relationship between physical performance and body composition variables, as well as the identification of seven characteristic profiles in this cohort.
Guided by stakeholder theory, a pair of exploratory studies identifies factors that influence firms to adopt an environmentally-friendly approach to conducting business, while providing insight into ...consumers' perceptions of such firms. An analysis of twenty in-depth interviews and a qualitative survey yields a conceptual model, indicating that such firms are motivated by governmental intervention, organizational values, and the potential benefits that can accrue as a result of implementation. Moreover, consumers view sustainably-oriented firms as maintaining procedures, developing products, and portraying themselves accordingly. These findings are relevant to academicians as they describe the underlying rationale for such behaviors and outline a novel conceptualization of the construct, thus invigorating future research. The results are also useful for firms as they shed light on sustainability efforts that are salient to the consumer and provide support for implementation, thereby encouraging the joint maximization of social and economic objectives.
