Two Worlds of Academic Publishing: Chemistry and German Sociology in Comparison

The communication infrastructure of modern science is provided by profit-oriented business firms: the publishing houses which print and distribute academic books and journals. Surprisingly, beyond some rather superficial impressions, in science studies little is known about how academic publishers work—in particular, how markets for books and journals look like, how publication decisions are taken, and how the interplay with the scientific community is arranged. We address these questions with a focus on the relation between economic considerations of publishers, on the one hand, and the requirements of scientific communication, on the other. Our contrasting case studies are a very large worldwide operating publisher with regard to chemistry publications and a national publishing house of German sociology. At first, we show how the rather different business approaches of the two types of academic publishing houses look like. Both approaches could reach stability for some time which means not only that publishers earned money according to their profit aspirations but also that the communication requirements of science were sufficiently met. Afterwards, we point out the instabilities that have begun to arise in both fields and may sooner or later erode the former fit of profit-making and scientific communication.     

The development of sensitivity to causally relevant dynamic information

The present study examined whether younger observers (kindergartners, second graders, and fourth graders) could extract relative weight information from collisions and also lifting events, and if they could judge whether collisions were natural (i.e., momentum conserving) or anomalous (non-momentum conserving). 20 children at each age and 20 adults viewed videotapes of 8 collisions (4 natural, 4 anomalous) and 6 sequences of lifting events. Observers also viewed sequences of static images taken from these events. Observers at all grade levels were able to reliably judge relative weight in both collisions and lifting events, and could differentiate between natural and anomalous collisions. Performance was much poorer when static sequences of the events were viewed, especially for the young children. A consistent age trend was noted across tasks: adults performed better than second and fourth graders who, in turn, performed better than kindergartners. In addition, there was evidence that younger children were differentially aided when the kinematics of the event made the kinetics more pronounced.

Preliminary studies on the hypoglycaemic effect ofAbroma augusta in alloxan diabetic rats

The hypoglycemic effect of the aqueous extract ofAbroma augusta (Family: Steculiceae) was studied in normal as well as alloxan diabetic rats. Treatement of diabetic rats with 4 ml (4gm dry weight) of agueous extract ofA. augusta for 16 weeks resulted in gradual but significant fall in fasting blood glucose and improvement in glucose tolerance. Serum total and LDL cholesterol and triacylglycerol which increased in diabetic rats showed improvement. These results show that the water extract ofA. augusta has both hypoglycemic and hypocholesterolemic effects.     

Mathematik — ein polarisierendes Schulfach

Zusammenfassung Mathematik ist ein polarisierendes Fach, ein Fach, das entweder geliebt oder abgelehnt wird. Der Beitrag fragt nach den Ursachen für eine derartige Polarisierung und beschreibt dabei die Stellung des Fachs Mathematik in der Schule. In einem ersten Teil werden unter Bezug auf die historische Entwicklung des Faches Mathematik die Zielsetzungen des Mathematikunterrichts beschrieben. Dabei wird deutlich, dass im Mathematikunterricht über die historische Entwicklung hinweg für die gymnasiale Bildung st?rker formale Ziele von Mathematik als Geistesbildung formuliert wurden, w?hrend für die Volks-und Realschulbildung st?rker materiale Bildung der Bef?higung zur Umweltbew?ltigung gefordert wurden. In einem zweiten Teil werden Probleme und Defizite des Mathematikunterrichts beschrieben wie die Dominanz von Regeln und Kalkülen und die einseitige Orientierung an einer deduktiv aufgebauten Fachsystematik. In einem dritten Teil werden Konsequenzen und Ma?nahmen zur Behebung der Defizite vorgeschlagen wie die Orientierung an fundamentalen Ideen. Auf der Ebene der Lehr-Lern-Formen wird die Bedeutung produktiver Lernumgebungen hervorgehoben sowie die St?rkung von Eigenaktivit?ten und offenen Fragestellungen gefordert.

Summary Mathematics — a polarizing subject. Mathematics is a polarizing subject, a subject either beloved or condemned. This contribution asks for the reasons for such polarization and, at the same time describes the position of Mathematics as a school subject. In the first part, the aims of mathematics teaching are described in relation with the historical development of mathematics. It becomes obvious that beyond its historical development mathematics teaching at the Gymnasium (higher type secondary school) was laying stronger emphasis on formal goals of mathematics such as the cultivation of the mind, while at the Volksschule (lower type secondary school) and Realschule (intermediate type secondary school) goals related to the ability of mastering daily life were more strongly demanded. In the second part problems and deficits of mathematics teaching are described, such as the prevailing dominance of rules and calculations and the unilateral orientation towards a deductively constructed systematics of the subject. In the third part consequences and measures for remedying the deficits are suggested, for example an orientation on fundamental ideas. At the level of teaching-and-learning-modes productive learning surroundings are demanded and the support of individually initiated activities and open problems is stressed.

What if new cars could adjust in-car devices to particular ways of speaking around the world? General Motors sought communication research to inform the design of culturally competent in-car human–machine interfaces. We discuss concerns and tensions that arise when balancing commitments of naturalistic study with design development goals. We emphasize the importance of awareness, attentiveness, and cooperation to ensure research integrity.     

A novel μ-fluidic whole blood coagulation assay based on Rayleigh surface-acoustic waves as a point-of-care method to detect anticoagulants

A universal coagulation test that reliably detects prolonged coagulation time in patients, irrespective of the anticoagulant administered, has not been available to date. An easily miniaturised, novel μ-fluidic universal coagulation test employing surface acoustic waves (SAW) is presented here. SAW was employed to instantly mix and recalcify 6 μl citrated whole blood and image correlation analysis was used to quantify clot formation kinetics. The detection of clinically relevant anticoagulant dosing with old anticoagulants (unfractionated heparin, argatroban) and new anticoagulants (dabigatran, rivaroxaban) has been tested and compared to standard plasma coagulation assays. The applicability of this novel method has been confirmed in a small patient population. Coagulation was dose-proportionally prolonged with heparin, argatroban, dabigatran, and rivaroxaban, comparable to standard tests. Aspirin and clopidogrel did not interfere with the SAW-induced clotting time (SAW-CT), whereas the strong GPIIb/IIIa-inhibitor abciximab did interfere. Preliminary clinical data prove the suitability of the SAW-CT in patients being treated with warfarin, rivaroxaban, or dabigatran. The system principally allows assessment of whole blood coagulation in humans in a point-of-care setting. This method could be used in stroke units, emergency vehicles, general and intensive care wards, as well as for laboratory and home testing of coagulation.
