History matters: The impact of reviews and sales of earlier versions of a product on consumer and expert reviews of new editions

Product reviews are assumed to be based on the observable characteristics of the underlying product. However, in the case of new editions in a product series, the determinants may include signals that originate from the reviews and the sales of editions that precede the focal product edition. Our analysis of 577 video games released in a series between 2000 and 2009 indicates that the reviews of earlier versions carry over to the reviews of the sequel by the same type of reviewer. We also find that expert reviews are influenced by the average review of previous editions by consumers and the average sales of previous editions of the product. This suggests that experts tend to adapt to the taste of consumers. Furthermore, it is found that a lack of consensus, between reviewers of a particular type, weakens the impact of average past reviews, whilst it magnifies the impact of the sales of earlier versions

Spectral quantification of nonlinear behaviour of the nearshore seabed and correlations with potential forcings at Duck, N.C., U.S.A

Local bathymetric quasi-periodic patterns of oscillation are identified from monthly profile surveys taken at two shore-perpendicular transects at the USACE field research facility in Duck, North Carolina, USA, spanning 24.5 years and covering the swash and surf zones. The chosen transects are the two furthest (north and south) from the pier located at the study site. Research at Duck has traditionally focused on one or more of these transects as the effects of the pier are least at these locations. The patterns are identified using singular spectrum analysis (SSA). Possible correlations with potential forcing mechanisms are discussed by 1) doing an SSA with same parameter settings to independently identify the quasi-periodic cycles embedded within three potentially linked sequences: monthly wave heights (MWH), monthly mean water levels (MWL) and the large scale atmospheric index known as the North Atlantic Oscillation (NAO) and 2) comparing the patterns within MWH, MWL and NAO to the local bathymetric patterns. The results agree well with previous patterns identified using wavelets and confirm the highly nonstationary behaviour of beach levels at Duck; the discussion of potential correlations with hydrodynamic and atmospheric phenomena is a new contribution. The study is then extended to all measured bathymetric profiles, covering an area of 1100m (alongshore) by 440m (cross-shore), to 1) analyse linear correlations between the bathymetry and the potential forcings using multivariate empirical orthogonal functions (MEOF) and linear correlation analysis and 2) identify which collective quasi-periodic bathymetric patterns are correlated with those within MWH, MWL or NAO, based on a (nonlinear) multichannel singular spectrum analysis (MSSA).

Innovators’ Acts of Framing and Audiences’ Structural Characteristics in Novelty Recognition

We integrate a rhetorical with an audience-mediated perspective on novelty recognition to advance a conceptual framework where recognition of novel ideas is understood as the result of the interplay between an innovator’s acts of framing and audiences’ structural characteristics. Building on storytelling and narrative research, we argue that innovators can overcome the liability of newness of their ideas by framing them so as to shape the evaluation of relevant audiences (e.g., peers, critics, investors or users). We also suggest that non-agentic mechanisms can render a field more or less permeable to the reception of novel ideas. Specifically, we propose that two audience-level characteristics affect novelty evaluation: audience heterogeneity and whether an audience is internal or external to cultural producers’ (including innovators’) professional community. Studying innovators’ acts of framing and marrying them with audience-level characteristics affords a window into a more nuanced understanding of how novel ideas are recognized and eventually accepted in cultural fields, thus offering several contributions to research on innovation and entrepreneurship and, more generally, social evaluation
