Choice Modeling With Context Effects: Generalization for Observational Data
Established procedures of analyzing the effect of context on choice consider simple, compact environments in laboratory settings. However, these approaches severely limit the study of context effects and, as a consequence, the applicability of their findings. In this paper, we generalize existing approaches in modeling choice with the aim of developing a toolbox for the analysis of observational data. We consider three main context measures: attr…

Differential Adaptive Diffusion: Understanding Diversity and Learning whom to Trust in Viral Marketing
Viral marketing mechanisms use the existing social network between customers to spread information about products and encourage product adoption. Existing viral marketing models focus on the dynamics of the diffusion process, however they typically: (a) only consider a single product campaign and (b) fail to model the evolution of the social network, as the trust between individuals changes over time, during the course of multiple campaigns. In t…

An Agent-Based Model of Urgent Diffusion in Social Media
During a crisis, understanding the diffusion of information throughout a population will provide insights into how quickly the population will react to the information, which can help those who need to respond to the event. The advent of social media has resulted in this information spreading quicker then ever before, and in qualitatively different ways, since people no longer need to be in face-to-face contact or even know each other to pass on …

Path dependence and the validation of agent‐based spatial models of land use
In this paper, we identify two distinct notions of accuracy of land‐use models and highlight a tension between them. A model can have predictive accuracy: its predicted land‐use pattern can be highly correlated with the actual land‐use pattern. A model can also have process accuracy: the process by which locations or land‐use patterns are determined can be consistent with real world processes. To balance these two potentially conflicting motivati…
Nonsurgical Factors That Influence the Outcome of Bariatric Surgery: A Review
OBJECTIVE: Severe obesity (ie, at least 100% overweight or body mass index > or =40 kg/m2) is associated with significant morbidity and increased mortality. It is apparently becoming more common in this country. Conventional weight-loss treatments are usually ineffective for severe obesity and bariatric surgery is recommended as a treatment option. However, longitudinal data on the long-term outcome of bariatric surgery are sparse. Available data…
Personality and dreaming: Boundary structure and dream content
Prior studies indicate that a personality dimension reflecting thin versus thick boundaries is related to global ratings of dream vividness, amount of emotion, and amount of interaction. In the present study, these relationships were examined by relating scores from the Boundary Questionnaire ( Hartmann, 1991) to dream content among 80 patients seen at a sleep disorders center. Thinness of boundaries was significantly correlated with dream length…
Adolescent growth in weight and its relation to menarche in contemporary American girls
Weight measurements at frequent intervals, from age six to adulthood, of 248 contemporary middle-class American girls were fitted to a mathematical model (Preece and Baines 1978). The results are used to examine weight and weight velocity at specified ages, the characteristics of the weight growth spurt and the relation of this spurt to menarche. These statistics are compared with previously complied height statistics for the same girls. Although…
Adolescent growth in height and its relation to menarche in contemporary American girls
Height measurements at frequent intervals, from age six to adulthood, of 338 middle-class American girls are used to examine contemporary height and height velocity at specified ages, the characteristics of the adolescent growth spurt and its relation to menarche. These data, analysed by fitting to a mathematical model (Preece and Baines 1978), are presented as tables of means and standard deviations, percentiles and correlations. There is no evi…
