The asymmetric impact of context effects on advantaged versus disadvantaged options
No full textDespite substantial prior research regarding the effect of context on choices, uncertainty remains regarding when particular context effects will be observed. In this paper we advance a new perspective on context-dependent choices, according to which context effects are a function of the relative advantage of one option over another and of the different strategies that decision-makers evoke when making a choice. We propose that context effects resulting from addition of a third option to a two-option set are more frequently observed when the added option is relatively similar (adjacent) to the “disadvantaged” alternative (i.e., the lower-share option) in a two-option set. In a series of studies we analyze the occurrence of context effects and find support for our predictions related to asymmetric dominance and extremeness aversion
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
In Defense of Consciousness: The Role of Conscious and Unconscious Inputs in Consumer Choice
No full textAlthough the argument that unconscious inputs are often key determinants of consumer decision making is compelling, it may be overstated, particularly with respect to consumer choice. A comparison of the role of conscious inputs (e.g., the attributes of options in the choice set) and unconscious inputs (e.g., a seemingly irrelevant observation or task) indicates that the former have a significant advantage. In particular, the impact of conscious inputs is supported by choice task norms and is less susceptible to being lost in the "noise" that is characteristic of most natural consumer environments (e.g., stores). Indeed, although consumers often have limited insight into influences and processes producing their choices, the assumption that consumers base their choices on conscious, willful evaluation of task-relevant inputs has been quite successful in explaining a wide range of phenomena. It is expected that future research will put greater emphasis on the interactions between conscious and unconscious influences.

Determinants of Customers' Responses to Customized Offers: Conceptual Framework and Research Propositions
No full textOver the past decade, marketers have been challenged by proponents of individual marketing (e.g., one-to-one marketing, mass customization, personalization) to shift from a focus on market segments to making individually customized offers. Specifically, marketers should develop "learning relationships" with their customers, be able to predict the customers' wants, and tailor their offerings to those preferences. Building on current knowledge regarding the manner in which customer preferences are constructed, the present research examines the basic premise of these new approaches and, specifically, the manner in which customers evaluate and respond to offers that are customized to their wants. A conceptual framework and a series of research propositions are presented regarding key determinants of customers' responses to customized offers, including (a) the characteristics of customers' preferences, (b) cues provided by the offer regarding its fit with the customers' preferences, (c) customers' receptivity to offers seen as customized to their preferences, and (d) the specific customized offer's content and format. The theoretical and practical implications of the framework and research propositions are discussed.
Will I Like A "Medium" Pillow? Another Look At Constructed And Inherent Preferences
No full textThere is a growing consensus that preferences are inherently constructive and largely determined by the task characteristics, the choice context, and the description of options. Although the fact that construction influences often play an important role is not in dispute, I argue that much of the evidence for preference construction reflects people's difficulty in evaluating absolute attribute values and tradeoffs and their tendency to gravitate to available relative evaluations. Furthermore, although some key demonstrations of constructive preferences involved rather unusual tasks and might have "benefited" from the effects they were demonstrating, the findings have led to rather sweeping, unqualified conclusions. The notion of more stable inherent preferences that are not determined by context is then highlighted, suggesting that it is often meaningful and useful to assume that people are non/receptive to certain aspects and object configurations, including those that may not yet exist. Inherent preferences are most influential when reference points and forces of construction are less salient, most notably, when objects are experienced. The final section explores some of the implications of constructed and inherent preferences with respect to decision and marketing research.
