This paper investigates the relation between liquidity and information based trading and the possible impact of market microstructure changes on this relationship. A model similar in spirit to that of wEasley et al. (1996b) J. Financ. 51(3) (1996) 811–833x is used to determine how often new information occurs and how it influences the composition of orders submitted to the market. There have be...

This paper provides an update and overview of the field of memory disorders and memory rehabilitation of adults.

Pilot studies using online social networks within a French University postgraduate course were conducted over a five-year period in order to explore and evaluate the relative advantages and challenges of such tools for tertiary education. Students were following a curriculum as part of a second-year predominantly off-campus Master’s degree. In this paper, after having defined pedagogical eLearn...

BACKGROUND Incarceration is common among people who inject drugs. Prior research has shown that incarceration is a marker of elevated risk for opioid overdose, suggesting that the criminal justice system may be an important, under-utilized venue for implementing overdose prevention strategies.

Timeliness and retention in a 6-month follow-up study were analyzed by subjects' baseline characteristics in a seroincidence study of 263 injection drug users at high risk of human immunodeficiency virus infection. Subjects were recruited from September 1997 to June 1998 in community settings in Philadelphia, Pennsylvania. Of these subjects, 93% were completers: 11% before the targeted date, 38...

OBJECTIVE To examine whether needle exchange program (NEP) use by injecting drug users (IDUs) affects injection risk behaviors over time. METHODS Between 1997 and 2000, 901 IDUs in Chicago were recruited for a cohort study from a multisite NEP and an area with no NEP. Participants were interviewed and tested for HIV at baseline and 3 annual follow-ups. Non-NEP users received HIV prevention se...

HIV epidemics are increasing among injection drug users throughout the world resulting from the sharing of contaminated needles. Many efforts, including syringe exchange programs (SEPs), have been initiated to curb the epidemics. Despite increased SEPs, IDUdriven HIV epidemics persist in many locations. For some cities with SEPs, many local IDU have experienced difficulties in accessing sterile...
