The authenticity premium: Balancing conformity and innovation in high technology industries

Research on categories and markets suggests that audiences rely on categorical distinctions to make sense of market offerings. Market offerings that deviate from category norms risk devaluation. Although literature in this area has led to valuable insights, scholars have begun to question whether there has been an overemphasis on conformity, leaving existing theories ill-equipped to account for innovation. Within this context, we argue that research on authenticity in cultural sociology offers a useful platform for theorizing. We draw on the work of Peterson (1997), who underscores the importance of signals in evaluation. Objective features of market offerings (e.g., quality) matter, but particularly for innovations, these features are not readily visible. Because authentic producers are typically thought to be more committed, capable, and intrinsically motivated, when visibility of such objective features is lacking, authenticity may serve as an alternative indicator of value. Appearing authentic requires signaling believability with respect to category norms, while also being distinctive. Using data on 684 firms from five high technology sectors, we explore the relationship between authenticity and investor perceptions of value. Focusing on three different proxies for signals of authenticity—networks, governance, and narratives—we find a curvilinear association between conformity/distinctiveness and Tobin's q. Consistent with our view of authenticity as a signal, we also find that this relationship flattens as firms gain better track records and face stiffer competition.     

Representational Issues in Students Learning About Evaporation

This study draws on recent research on the central role of representation in learning. While there has been considerable research on students’ understanding of evaporation, the representational issues entailed in this understanding have not been investigated in depth. The study explored students’ engagement with evaporation phenomena through various representational modes. The study indicates how a focus on representation can provide fresh insights into the conceptual task involved in learning science through an investigation of students’ responses to a structured classroom sequence and subsequent interviews over a year. A case study of one child’s learning demonstrates the way conceptual advances are integrally connected with the development of representational modes. The findings suggest that teacher-mediated negotiation of representational issues as students construct different modal accounts can support enriched learning by enabling both (a) richer conceptual understanding by students, and (b) enhanced teacher insights into students’ thinking.     

Role of the microcomputer‐based laboratory display in supporting the construction of new understandings in thermal physics

Teachers' failure to use the microcomputer‐based laboratory (MBL) more widely may be a result of not recognizing its capacity to transform laboratory activities. This research aimed to increase understanding of how MBL activities designed to be consistent with a constructivist theory of learning support or constrain student construction of understanding. The first author conducted the research with his Year 11 physics class of 15 students. Dyads addressed 10 tasks in thermal physics using a predict–observe–explain format. Data sources included video and audio recordings of students and teacher during four 70‐minute sessions, students' computer data and written notes, semistructured student interviews, and the teacher's journal. Analysis of students' discourse identified many instances in which students' initial understandings of thermal physics were mediated in multiple ways by the screen display. The findings are presented as eight assertions. Recommendations are made for developing pedagogical strategies incorporating MBL activities that will likely catalyze student construction of understanding. © 2004 Wiley Periodicals, Inc.

Deconstructing learning in science—Young children's responses to a classroom sequence on evaporation

Five year old children's ideas were tracked by a range of means during and subsequent to a classroom sequence on evaporation. They held a range of conceptions which changed in complex ways across context and time. These could only be made sense of by moving outside traditional conceptual change interpretations to include broader notions of appropriation of language as a cultural tool, of personal and social narrative responses to features of the phenomena and the classroom setting, and the nature of science explanations. The findings are used to explore the relationship between social and individual perspectives on learning, and to question some assumptions underlying conceptual change research.     

Serial pattern learning of temporal intervals

The problem was to determine how rats adjust the times of their lever responses to repeating sequences of interfood intervals. In Experiment 1, rats were trained on an interval schedule of reinforcement with a 12-element Fleshler-Hoffman series with a mean of 60 sec; the order was as follows: ascending, random with repetition, random with replacement, random without replacement. In Experiment 2, rats were trained with a 10-element ascending or descending series (from 2⁰ to 2⁹ sec), and in a ramp procedure in which these intervals increased and then decreased repeatedly. In the ascending, descending, and ramp conditions (but not in the random conditions), postreinforcement pause (PRP) was a function of the interval. PRP was most highly correlated with an interval later in the series. Theories of conditioning and timing based on the averaging of past experience must be modified to account for such anticipatory behavior.     

Racial Identity and Psychological Symptoms Among African Americans Attending a Historically Black University

Previous research found racial identity predictive of psychological distress among African American students at predominantly White colleges. This study examined these relationships among 154 African American undergraduates attending a historically Black university. Racial identity was independent of psychological distress, suggesting that African American students' racial identity predicts psychological distress only in settings in which they are the minority.
