SummaryThe cold promoted shortening of the thrombotest-times occuring in the plasmas of the majority of women on oral contraception or in the last trimester of pregnancy when incubated overnight at 0°–4° was investigated.The short thrombotest-times were caused by activation of factor VII in a time consuming reaction. Activation was also revealed in the intrinsic coagulation system, but the changes in the activities of coagulation factors other than factor VII were small.Comparison was made between clot promoting effects of cooling and contact, and it was concluded that while contact apparently exerted its main effect in the intrinsic system, cooling predominately activated the extrinsic plasma coagulation system.The cold promoted activation of factor VII seemed to be brought about by an activator.

A congenital Antithrombin III (AT III) deficiency affecting 7 members of 3 families is reported.The first throrabo-embolic accidents were observed between the age of 22 and 35 : they were spontaneous or occured after delivery or oral contraception. in one patient, a deep vein thrombosis was observed during heparin treatment. in 2 cases, recurrent pulmonary embolic episodes required vena cava ligation. No thromboembolic accident was observed during oral anticoagulation.AT III was measured by an amidolytic method and by the Mancini method on plasma and serum ; the antithrombin activity was determined on serum by the von Kaulla method. in 7 patients, a decreased AT III was found by all the methods performed. The AT III level was around 50 % in patients treated or not by oral anticoagulants One patient was studied during heparin treatment and then under oral anticoagulants : AT III levels were lower under heparin.

This paper illustrates the information literacy (IL) strategy in an undergraduate Management program at U.S. Coast Guard Academy. The paper exemplifies a sequential approach that improves students’ capabilities to evaluate and apply information in a specifically designed learning environment while generating new knowledge in undergraduate business coursework. The paper also emphasizes how IL can be developed within management coursework through a six-step process, including defining, locating, selecting, organizing, presenting, and assessing.  This specially designed framework of IL learning can be applied across all relevant courses using specially designed assignments in the Management major.

Sex and reproduction lie at the heart of studies of insect behavior. We begin by providing a brief overview of insect anatomy and physiology, followed by an introduction to the overarching themes of parental investment, sexual selection, and mating systems. We then take a sequential approach to illustrate the diversity of phenomena and concepts behind insect reproductive behavior from pre-copulatory mate signalling through copulatory sperm transfer, mating positions, and sexual conflict, to post-copulatory sperm competition, and cryptic female choice. We provide an overview of the evolutionary mechanisms driving reproductive behavior. These events are linked by the economic defendability of mates or resources, and how these are allocated in each sex. Under the framework of economic defendability, the reader can better understand how sexual antagonistic behaviors arise as the result of competing optimal fitness strategies between males and females.
