Reflections on Replications

We are immensely pleased to see a publication dedicated to replications in the IS field (Dennis and Valacich, 2014). We believe it is long overdue and will serve a useful and path breaking function in the Information Systems discipline and, perhaps, in the larger academic community (Berthon, et al., 2002). Toward that end, we share our particular view of replication: why it is important and how various types of replications may co-exist. We also offer some thoughts about ways that researchers might go about this type of research that will add value to their own work and more effectively add value to the body of knowledge that represents the IS discipline

Green Grass, High Cotton: Reflections on the Evolution of the Journal of Advertising

This article reflects on my time as the fifth editor of the Journal of Advertising, makes observations about the evolution of scholarship in the Journal over the past decades, offers suggestions for how JA might advance in the coming years, and provides some “words of wisdom” to advertising researchers. Because it is the first in an invited article series of editor reflections, a bit of historical context is provided

Local antithetic sampling with scrambled nets

We consider the problem of computing an approximation to the integral $I=\int_{[0,1]^d}f(x) dx$. Monte Carlo (MC) sampling typically attains a root mean squared error (RMSE) of $O(n^{-1/2})$ from $n$ independent random function evaluations. By contrast, quasi-Monte Carlo (QMC) sampling using carefully equispaced evaluation points can attain the rate $O(n^{-1+\varepsilon})$ for any $\varepsilon>0$ and randomized QMC (RQMC) can attain the RMSE $O(n^{-3/2+\varepsilon})$, both under mild conditions on $f$. Classical variance reduction methods for MC can be adapted to QMC. Published results combining QMC with importance sampling and with control variates have found worthwhile improvements, but no change in the error rate. This paper extends the classical variance reduction method of antithetic sampling and combines it with RQMC. One such method is shown to bring a modest improvement in the RMSE rate, attaining $O(n^{-3/2-1/d+\varepsilon})$ for any $\varepsilon>0$, for smooth enough $f$.Comment: Published in at http://dx.doi.org/10.1214/07-AOS548 the Annals of Statistics (http://www.imstat.org/aos/) by the Institute of Mathematical Statistics (http://www.imstat.org

The Bigman Metaphor for Entrepreneurship: A Library Tale with Morals on Alternatives for Further Research

Melanesian Bigmanship (a meritocratic, enacted career of political-economic leadership) is recounted as an anthropological metaphor for entrepreneurship. This “library tale” has two purposes. The first is a demonstration of conceptual uses of ethnographies for developing grounded theory. Propositions are generated on entrepreneurial orientations and opportunity structures. Opportunities are seen to arise in the creation of linkages between spheres of exchange, or fields in which an object exchanges at different values. Entrepreneurial tactics, such as converting between spheres, call for skills in informal planning, astute use of timing, and networking. These “tactical” skills coexist with “moral” skills, in persuasiveness, the manipulation of norms, and recognition of culturally specific opportunities. The entrepreneur\u27s acts thus create a dialectic of moral (normatively approved) and tactical (instrumentally enacted) changes. The second purpose is a demonstration of methodological implications of ethnographies. Library tales are helpful in the process of “constant comparison” (Glaser and Strauss 1967), by augmenting available, within-site observations with other sources of insight, and of potential disconfirmation of emerging ideas. However, there are limits to the “translation” of library tales. There thus arises a need for observations tailored to specific comparative questions. Multiple site case replication research is suggested for tailoring observations to synchronic, comparative uses. Processual, continuous contextual analysis is suggested for diachronic, intensive followups to such questions as the relationships amongst constraints and individual agency

Does “Evaluating Journal Quality and the Association for Information Systems Senior Scholars Journal Basket…” Support the Basket with Bibliometric Measures?

We re-examine “Evaluating Journal Quality and the Association for Information Systems Senior Scholars Journal Basket…” by Lowry et al. (2013). They sought to use bibliometric methods to validate the Basket as the eight top quality journals that are “strictly speaking, IS journals” (Lowry et al., 2013, pp. 995, 997). They examined 21 journals out of 140 journals considered as possible IS journals. We also expand the sample to 73 of the 140 journals. Our sample includes a wider range of approaches to IS, although all were suggested by IS scholars in a survey by Lowry and colleagues. We also use the same sample of 21 journals in Lowry et al. with the same methods of analysis so far as possible. With the narrow sample, we replicate Lowry et al. as closely as we can, whereas with the broader sample we employ a conceptual replication. This latter replication also employs alternative methods. For example, we consider citations (a quality measure) and centrality (a relevance measure in this context) as distinct, rather than merging them as in Lowry et al. High centrality scores from the sample of 73 journals do not necessarily indicate close connections with IS. Therefore, we determine which journals are of high quality and closely connected with the Basket and with their sample. These results support the broad purpose of Lowry et al., finding a wider set of high quality and relevant journals than just MISQ and ISR, and find a wider set of relevant, top quality journals
