Diffusion Research Traditions and the Spread of Policy Innovations in a Federal System

This essay summarizes the state of research on policy diffusionamong the American states. Recognizing that this policy diffusionliterature largely exhibits a geographic focus rather than theclient focus predominant in most other diffusion research, theargument is nevertheless made that this field of diffusion studieshas not yet become welded into a distinctive college of mutuallyaware scholars. Still, following Everett Rogers' model of thediffusion process, American state policy diffusion studies arereviewed so as to present emerging generalizations, currentblindspots suggested by Rogers' model, and departures from otherdiffusion research findings. Diffusion of judicial innovationsis reviewed separately as a special subset of policy diffusionresearch. Finally, policy diffusion research is related to largerconcerns with societal development and change and with democraticpolitics.     

Parental Influence on Eating Behavior: Conception to Adolescence

The first years of life mark a time of rapid development and dietary change, as children transition from an exclusive milk diet to a modified adult diet. During these early years, children's learning about food and eating plays a central role in shaping subsequent food choices, diet quality, and weight status. Parents play a powerful role in children's eating behavior, providing both genes and environment for children. For example, they influence children's developing preferences and eating behaviors by making some foods available rather than others, and by acting as models of eating behavior. In addition, parents use feeding practices, which have evolved over thousands of years, to promote patterns of food intake necessary for children's growth and health. However in current eating environments, characterized by too much inexpensive palatable, energy dense food, these traditional feeding practices can promote overeating and weight gain. To meet the challenge of promoting healthy weight in children in the current eating environment, parents need guidance regarding alternatives to traditional feeding practices.     

Intergenerational Transmission: Physical Abuse and Violent vs. Nonviolent Criminal Outcomes

In this paper we test several specific hypotheses derived from the intergenerational transmission of violence thesis to see if exposure to physical abuse has a special role in the etiology of violence. We employ a systematic statistical approach using data from the National Longitudinal Study of Adolescent Health (Add Health). Our findings suggest that a history of physical abuse is strongly associated with frequency of violence, but the association is not specific to violence and is mediated by their common association with nonviolent offending. Further, the association between physical abuse and violence is not significantly larger than the association between neglect or sexual abuse and violence. In summary, the data suggest that the association between abuse and violence is not unique to physical abuse and that the impact of physical abuse is not specific to violent behavior.     

Chemical enhancement of footwear impressions in blood on fabric — Part 3: Amino acid staining

Enhancement of footwear impressions, using ninhydrin or ninhydrin analogues is not considered common practice and such techniques are generally used to target amino acids present in fingermarks where the reaction gives rise to colour and possibly fluorescence. Ninhydrin and two of its analogues were used for the enhancement of footwear impressions in blood on various types, colours and porosities of fabric. Test footwear impressions on fabric were prepared using a specifically built rig to minimise the variability between each impression. Ninhydrin enhancement of footwear impressions in blood on light coloured fabric yielded good enhancement results, however the contrast was weak or non-existent on dark coloured fabrics. Other ninhydrin analogues which have the advantage of fluorescence failed to enhance the impressions in blood on all fabrics. The sequential treatment of impressions in blood on fabric with other blood enhancing reagents (e.g. protein stains and heme reagents) was also investigated.     

State institutions, political power and social policy choices: Reconstructing the origins of Nordic models of social policy

Abstract.  The origins of the Nordic social policy model(s) need to be viewed broadly and historically from its late nineteenth-century initiation to the immediate postwar period (1940s to the early 1960s), when a social democratic model began to consolidate. In reference to the alternate social policy traditions of British poor relief and German occupational insurance, this article analyzes the sociopolitical contexts that finally prevented Scandinavian states from developing similarly, instead enabling development of universalistic social policy. The historical narratives are arranged with respect to four analytical aspects: policy development; the configuration of state institutions; the strength of liberal, conservative and leftist power blocs; and intra-Nordic divergence in all these respects. Such an approach integrates state-centred and power-resources-focused analyses of Nordic welfare.
