Interacting Socially With Human Hands at 24 Months of Age

This experiment explored whether or not 2‐year‐olds would engage in synchronic imitation with human hands. Sixty‐four 24‐month‐old infants participated. In a test of synchronic imitation, infants were given a toy while a model simultaneously performed novel actions on an identical toy. Infants were randomly assigned to 1 of 4 model conditions: a familiar person, an unfamiliar person, disembodied human hands, and disembodied robotic pincers. Infants were as likely to synchronically imitate disembodied hands as a person. Imitation of the pincers was significantly lower. This pattern suggests that 2‐year‐olds will engage socially with human hands in the absence of the rest of the body.     

Handlungserklärung und die zwei Rationalitäten?

The question is being scrutinized how to integrate into a general theory of action the two types of rational action distinguished by Max Weber based on value rationality and instrumental rationality. Three proposals recently made by Raymond Boudon, Siegwart Lindenberg and Hartmut Esser are considered. These authors agree in conceiving rationality as based on reasons. But, unlike Boudon, Lindenberg and Esser hold that rationality should be essentially considered as consequential and that it is possible to reconstruct value-rational action in this framework, although Weber’s formulation of this type of action clearly excludes a reference to consequences. According to Lindenberg and Esser, this reconstruction of value-rational action can be accomplished by the theory of subjective expected utility supplemented by a concept of framing. In their opinion this kind of model also offers the opportunity to construct a conception superior to a mere typology of action orientations, because it enables us to specify under what conditions which type of action prevails. The article provides evidence that the proposals made by both authors still fall short of offering an adequate model for understanding the difference between both types of action. Lindenberg’s proposal does not sufficiently allow for explaining the difference between traditional and value-rational action and the claim for justification associated with value-rational action. Esser’s conception meets these two criteria but it remains unsettled whether his model already specifies sufficient conditions for value-rational action. The article concludes in considering the general question whether it is conceivable to derive both types of action from a common notion of rationality.     

On the Distribution of Likelihood Ratio Test Statistics for Cointegration Rank

This paper analyses the likelihood ratio test for the hypothesis of reduced cointegration rank in a Gaussian vector autoregressive model. The usual asymptotic distribution typically gives rather large size distortions. This is explained by the fact that the asymptotic distribution of the likelihood ratio test statistic varies across the parameter space. A much improved distribution approximation can be obtained using local asymptotic theory. The idea is discussed for some low dimensional examples.     

Current Directions in Risk Research: New Developments in Psychology and Sociology

This article reviews the main approaches to risk in psychology and sociology and considers recent developments. It shows that research continues from a wide range of perspectives. Some developments in psychological thinking have recently acknowledged the importance of the cultural framing of risk perceptions and responses and the positive power of emotions to manage uncertainties, while some streams of work in sociology have moved toward more individualist approaches. These converging processes open opportunities for cross-fertilization and for using insights from both disciplines in the development of research.     

Gemeinschaftliche Formen der Sicherheitsgewährleistung zur Ergänzung staatlicher Kontrollpolitik

Motivated by the debate on ‘broken-windows’ politicians discovered the safety of communities as suitable for participation. The article deals with this connection between a former pure state task and civil engagement. The empirical focus aims at different organisational forms of community-watch projects. All of them cause different forms of participation. The more civic engagement is related to community-networks the better social control of urban communities can be provided by citizens.     

Transportation Hardship: Are You Better off with a Car?

Growing evidence demonstrates the importance of transportation in improving family economic well being. This article sheds light on the hardship that one important transportation asset, private vehicles, may exert on families. Data from the Iowa Transportation and Employment Survey provided a unique opportunity to understand how vehicle access enables households to meet their basic needs, but may exacerbate their problems through the creation of additional demands on resources. Approximately 26% of the sample reported having experienced transportation hardship. The strongest predictors of transportation hardship were the presence of children in the household, low income, driving less reliable vehicles, and the unavailability of transportation assistance from someone outside the household. How to help families meet their transportation needs in light of this evidence remains open to debate.
