Do self-reports of procrastination predict actual behavior?

Objectives: Procrastination is typically assessed via self-report questionnaires. So far, only very few studies have examined actual procrastination behavior, providing inconclusive results regarding the real-life validity of self-reports in this domain. The present study aimed to examine for the first time whether participants' self-reported procrastination can predict their actual behavior on a real-life task.

I could do it now, but I'd rather (forget to) do it later: examining links between procrastination and prospective memory failures.

Prospective memory (PM) represents the ability to remember to perform planned actions after a certain delay. As previous studies suggest that even brief task-delays can negatively affect PM performance, the current study set out to examine whether procrastination (intentionally delaying task execution despite possible negative consequences) may represent a factor contributing to PM failures. Specifically, we assessed procrastination (via a standardized questionnaire as well as an objective behavioral measure) and PM failures (via a naturalistic PM task) in 92 young adults.

DI-5-CUFFS: Venoconstrictive Thigh Cuffs Limit Body Fluid Changes but Not Orthostatic Intolerance Induced by a 5-Day Dry Immersion.

Venoconstrictive thigh cuffs are used by cosmonauts to ameliorate symptoms associated with cephalad fluid shift. A ground simulation of microgravity, using the dry immersion (DI) model, was performed to assess the effects of thigh cuffs on body fluid changes and dynamics, as well as on cardiovascular deconditioning. Eighteen healthy men (25-43 years), randomly divided into two groups, (1) control group or (2) group with thigh cuffs worn 10 h/day, underwent 5-day DI.

Chromosome 13 abnormalities in multiple myeloma are mostly monosomy 13.

Chromosome 13 abnormalities are frequently observed in multiple myeloma (MM). Several reports recently demonstrated the strong prognostic value of these abnormalities, associated with a short survival. Cytogenetic studies have shown that most of these abnormalities are complete monosomies.

Cytogenetic, interphase, and multicolor fluorescence in situ hybridization analyses in primary plasma cell leukemia: a study of 40 patients at diagnosis, on behalf of the Intergroupe Francophone du Myélome and the Groupe Français de Cytogénétique Hématologique.

Primary plasma cell leukemia (PCL) is a rare plasma cell malignancy. Consequently, few large reports have been published. Presented is a cytogenetic analysis of 40 patients with primary PCL compared with 247 newly diagnosed patients with stage III multiple myeloma (MM).
