Individual and social determinants of winning bids in online auctions

• Online auctions have grown in popularity since the inception of eBay in 1995. Yet despite the phenomenal growth, little is understood about the individual and collective motivations of consumers that lead to higher bids and ultimately, higher profits. This research reframes auction theory in terms of consumer behavior theory and uses observational data to assess bidder‐generated behavior in response to seller‐generated decisions. Results suggest that an increased number of visual cues (pictures) influences bids placed early in the auction and that those early bids generate activity among other bidders, subsequently resulting in higher winning bids. In addition, our findings indicate that the starting price, as determined by the seller, also impacts the final winning bid. Research and seller implications are offered, as are future directions for research in studying this still new phenomenon.

Ethics and professionalism: what does a resident need to learn?

Training in ethics and professionalism is a fundamental component of residency education, yet there is little empirical information to guide curricula. The objective of this study is to describe empirically derived ethics objectives for ethics and professionalism training for multiple specialties. Study design is a thematic analysis of documents, semi-structured interviews, and focus groups conducted in a setting of an academic medical center, Veterans Administration, and community hospital training more than 1000 residents. Participants were 84 informants in 13 specialties including residents, program directors, faculty, practicing physicians, and ethics committees. Thematic analysis identified commonalities across informants and specialties. Resident and nonresident informants identified consent, interprofessional relationships, family interactions, communication skills, and end-of-life care as essential components of training. Nonresidents also emphasized formal ethics instruction, resource allocation, and self-monitoring, whereas residents emphasized the learning environment and resident-attending interactions. Conclusions are that empirically derived learning needs for ethics and professionalism included many topics, such as informed consent and resource allocation, relevant for most specialties, providing opportunities for shared curricula and resources.     

Interfacial waves between piezoelectric and piezomagnetic half-spaces with magneto-electro-mechanical imperfect interface

Abstract

We study the propagation of shear horizontal waves between the interface of piezoelectric and piezomagnetic half-spaces with a magneto-electro-mechanical imperfect contact. Mechanical, electrical and magnetical imperfections are modelled by means of a spring, a capacitor and a inductor, respectively. A general expression for the dispersion relation not reported previously in literature is given in an explicit form, with the diverse limit cases analysed in detail. In some of these limit cases, new expressions are also obtained which predict the existence of interfacial waves. In the other cases, when already reported results exist, a comparison with them is done. Some physical interpretations are derived from the limit cases. The influence of mechanical, electrical and magnetical imperfect contacts are shown in some numerical examples.     

Opening What Has Been Closed,Relaxing What Has Been Clenched: Dissociation and Enactment Over Time in Committed Relationships

I use dissociation and the concept of the multiple self to link Mitchell's profound insight with Goldner's critique. In the process, I use the idea of dissociation to think about the nature of different kinds of long-term relationships.     

“One Never Knows,Do One?”: Commentary on Paper by the Boston Change Process Study Group

I discuss the work of the Boston Change Process Study Group, focusing on the paper in this issue of Psychoanalytic Dialogues, but also addressing broader issues across the range of their work. After describing the considerable similarities between their views and mine, I focus on three areas about which I have questions: the concept and clinical use of mutual enactment, BCPSG's use of nonlinear dynamic systems theory, and certain problems revolving around science and social construction.     

The Fusion of Horizons: Dissociation,Enactment, and Understanding

All understanding is context dependent, and one of the most significant contexts for clinical purposes is the self-state. How we understand the other, and ourselves, depends on the state(s) we occupy. Dissociations between an analyst's self-states can, therefore, limit or impede understanding of the analysand by depriving the analyst of a fitting context within which to grasp what the analysand says and does. Clinical understanding may require the breach of such dissociations. I lay out some of the implications of thinking about transference and countertransference along these lines, with detailed examples illustrating the consequences of the analyst's dissociations and their eventual resolutions. Among the advantages of this way of thinking is that it amounts to a psychoanalytic account of the hermeneutic circle.     

The Interpersonal Field: Its Place in American Psychoanalysis

Today the concept of the interpersonal field, while seldom credited to those who created it, is widely used in psychoanalysis. After reviewing how the concept of the field defines interpersonal and relational psychoanalysis, I take up the rejection of the idea in American mainstream psychoanalysis in the decades just after it was proposed by Sullivan and Fromm, why that rejection took place, and how the entire discipline of psychoanalysis in North America might have fared if the idea had been widely recognized earlier than it was.     

Field Theory in Psychoanalysis,Part I: Harry Stack Sullivan and Madeleine and Willy Baranger

This is the first of two articles comparing conceptions of the field in interpersonal/relational psychoanalysis (IRP) and Bionian field theory (BFT). This article compares the thinking of the originators of IRP and BFT, Harry Stack Sullivan and Madeleine and Willy Baranger.     

Breathing Together: Reply to Harris and Shaw

These two very different but complementary discussions address two different “registers” of my thinking in my paper on patients who “live in airless intrapsychic worlds.” Harris is most interested in the meta-theoretical and historical contexts and frames of my theory and clinical approach, viewing my contribution as an example of various broad trends in contemporary relational psychoanalytic thought. Shaw, by contrast, engages with my particular insights and clinical/theoretical framework for understanding and working with patients whose struggles very much resemble and overlap with the struggles of the adult children of “traumatically narcissistic” parents, which his seminal work has focused on. In my Replies I voice my appreciation of each of their unique perspectives on my ideas, and engage with each of them regarding certain differences in our theoretical and clinical sensibilities.     

The Hard-to-Engage Patient: A Treatment Failure

I discuss the relatedness with certain hard-to-engage patients as a kind of dissociative enactment, and I present a case illustration of a man whom I liked but could not help.
