Parent-child Communication,Social Norms,and the Development of Cyber Aggression in Early Adolescence

Journal of Youth and Adolescence - To understand the development of cyber aggression during adolescence, it is important to consider the temporal variability of its potential predictors. This study...     

On the Viability of the Concept of Staatswissenschaften

Staatswissenschaften is said to mean that there are certain specific fields of scholarly inquiry and higher education that relate primarily to the state, which is defined widely as structured human living-together. It is outlined why this is a concept viable for the future, particularly—but not only—in and for Europe.     

Ring fractures of the base of the skull

Besides complete ring fracture, also incomplete fractures open to the front, back, or side(s) are discussed on the basis of 61 ring fractures of the base of the skull. The fractures were found in casualties from traffic accidents (car passengers, cyclists and motorcyclists, pedestrians), after falls and other accidents. In traffic accidents, compression, traction, hyperextension, extreme lateral movements, and torsional forces can lead to ring fractures. In falls, compression and traction are the main forces. A fall in one plane is also capable of producing an incomplete ring fracture. Incomplete ring fractures may show lateral emphasis. The greater fracture length is found on the impact side (e.g., in falls). In contrast to complete ring fractures, incomplete ring fractures are compatible with longer survival times. Ring fractures are to be classified under direct fractures. This does not exclude the possibility that overall deformations of the skull with bursts can partly determine the course of the fracture.     

1.1. HLA and other leucocyte and platelet alloantigens in paternity testing (introductory lecture)

The analysis of lipstick stains presented here is a combination of several techniques. In addition to colour comparison and thin-layer chromatographic (TLC) analysis, X-ray analysis in a scanning electron microscope and high-performance liquid-chromatographic (HPLC) analysis have been used. X-ray analysis may be performed directly on the material bearing the stain. For TLC and HPLC analyses a solvent extract of the stain was used.Guidance is given for practical examination of lipstick stains. When using all the methods described in this paper, all the 117 different lipstick samples examined in this study could be distinguished from each other.     

COMPETITION POLICY WITH OPTIMALLY DIFFERENTIATED RULES INSTEAD OF "PER SE RULES VS RULE OF REASON"

Both in U.S. antitrust and EU competition policy, a developmentto a broader application of rule of reason instead of per serules can be observed. In the European discussion the attemptto base competition policy on a "more economic approach" ismainly viewed as improving the economic analysis in the assessmentof specific cases. In this paper it is shown from a generallaw and economics perspective that the application of rulesinstead of focussing on case-by-case analyses can have manyadvantages (lower regulation costs, rent-seeking, and knowledgeproblems), although an additional differentiation of rules througha deeper assessment can also have advantages in regard to thereduction of decision errors of type I and II. After introducingthe notion of a continuum of more or less differentiated rules,we show—based upon law and economics literature upon theoptimal complexity of rules—in a simple model that a competitionrule is optimally differentiated if the marginal reduction ofthe sum of error costs (as the marginal benefit of differentiation)equals the marginal costs of differentiation. This model alsoallows for a more detailed analysis of the most important determinantsof the optimal degree of rule-differentiation. From this lawand economics perspective, competition policy should consistmainly of (more or less differentiated) rules and should onlyrarely rely on case-by-case analysis. Therefore the main taskof a "more economic approach" is to use economics for the formulationof appropriate competition rules.
