Social and mobile technologies offer users unprecedented opportunities for communicating, interacting, sharing, meaning-making, content and context generation. And, these affordances are in constant flux driven by a powerful interplay between technological innovation and emerging cultural practices. Significantly, also, they are starting to transcend the everyday lifeworlds of users and permeat...

People encounter an almost overwhelming quantity of information about human behavior and the social world everyday. Despite this information overload, humans are markedly adept at finding signal in the noise, interpreting the inputs in their complex environments in a way that both simplifies and makes meaning. People use a variety of shortcuts or heuristics to make sense of these stimuli (Tvers...

Three hundred and five traditional college students and 159 baby boomers (40–55 years old) in China participated in the study with Kogan’s Attitude toward Old People [Kogan (1961) Journal of Abnormal and Social Psychology, 62(1), 44–54] being used. Results from ANOVA showed overall, baby boomers held more positive attitudes toward older people than college students. There was a significant inte...

I show that multiproduct firms suffer less than single-product firms from the “Diamond Paradox”. Equilibrium prices are high because rational consumers understand that visiting a store exposes them to a hold-up problem when they have search costs. However a store with more products attracts more consumers with low valuations, and therefore charges lower prices. Advertising a few products at low...

The Chinese social security system is undergoing a series of reforms. These reforms are often the government's short-term responses to imminent financial and social pressure. The long-term impacts, especially those on economic efficiency, are often ignored. The background of the Chinese social security system reform is unique. Like many other countries (mainly more advanced economies), China is...

Moreover, the deep introduction of Internet in our lives both at personal and business level is changing all aspects of our economies and societies and the way enterprises and individuals interoperate and collaborate. In...

People typically move and act under the constraints of an environment, making human behavior strongly place-dependent. Motion patterns, the places and the rates at which people appear, disappear, walk or stand are not random but engendered by the environment. In this paper, we learn a non-homogeneous spatial Poisson process to spatially ground human activity events for the purpose of people tra...

We present in this paper a system for passengers counting in buses based on stereovision. The objective of this work is to provide a precise counting system and adapted to buses environment. The processing chain corresponding to this counting system involves several blocks dedicated to the detection, segmentation, tracking and counting. From original stereoscopic images, the system operates pri...

During the period of exceedingly critical news coverage surrounding the Monica Lewinsky debacle, President Bill Clinton’s job approval ratings were at some of the highest levels they reached during his tenure in office. Given this public response, many pollsters, pundits, and scholars argued that news coverage of the scandal must have been largely irrelevant to the public. Our view counters the...
