A risk assessment of salmonellosis linked to chicken meals prepared in households of China

A quantitative microbiological risk assessment model was used to quantify the risk of salmonellosis caused by bacterial growth and cross-contamination of chicken meals prepared in households of China. Chinese data on initial loads of Salmonella in chicken carcasses sold at retail, storage time and handling of raw chicken meat in household kitchens and confirmatory transfer rates of Salmonella among different kitchen objects were collected. Only one third of Chinese families in our sample separated the cutting board between raw and ready-to-eat foods. The cross-contamination of ready-to-eat foods from chicken meals via the cutting board, the knife and cooks’ hands increased the frequency of pathogen ingestion and the risk of salmonellosis. A significant decrease in the risk of salmonellosis could be achieved by reducing the cross-contamination when handling raw chicken meat and ready-to-eat foods. Decreasing the prevalence of Salmonella contamination to 8.8% or removing chicken carcasses with contamination densities higher than 100 MPN/100 g at retail was less effective. Using transfer rates of Salmonella from raw chicken meat to the wooden cutting board instead of that from references, a statistically higher risk of salmonellosis per serve due to the cross-contamination in households was observed. The present study validated values of hygiene practices in China to reduce the risk of salmonellosis from contaminated raw chicken meat at retail. Deliberate surveys for cooking behaviors and transfer rates of Salmonella from and to different objects including wooden cutting boards were needed.     

Varieties of religion–family linkages.

Comments on the articles by A. Mahoney et al (see record 2001-05578-002), B. H. Fiese and T. J. Tomcho (see record 2001-05578-003), K. T. Sullivan (see record 2001-05578-004), and D. L. Flor and N. Flanagan Knapp (see record 2001-05578-005). The 4 articles in this special issue make important contributions to both family and religious studies as well as to their interface. This commentary begins by considering 4 unifying themes present across all of the articles, including meaningful religion-family linkages, the importance of gender differences in the faith-family interface, the significance of intergenerational relationships, and the need for better theory. The authors then discuss the unique major strength and secondary limitations of each study. Finally, the commentary focuses on two challenges inhibiting the contemporary study of religion and the family--a relative lack of racial and religious diversity in samples and the lack of a unifying theory of religion--family linkages--and suggests how to adjust the trajectory of future theory and research to address these issues.

The "never-to-be-forgotten investigation": Luella W. Cole, Sidney L. Pressey, and mental surveying in Indiana, 1917–1921.

The case of Cole and Pressey's mental survey of southern counties in Indiana provides a microhistorical view of intelligence testing and its popularization. Providing fresh insight into the nature and commerce of mental surveying outside of the Army's notorious program during World War I, this case is an example of larger phenomena at that time. Intent on popularizing their products, Cole and Pressey attended to the minutiae of the consumption and production of their psychological apparatus in their attempts to create and satisfy market conditions. Here, markets would dictate the success of their scales, and in turn mediate their psychology. I argue that the popularization of intelligence testing had as much to do with the mundane market practices of psychologists as with the intellectual practices of Army elites.

Geographies of Knowledge Formation in Firms

This paper focuses on the spatial dimension of learning in firms. It works with important new insights in economic geography that stress the role of spatial proximity and territorial embeddedness in the process of knowledge formation, but it also seeks to go beyond them by recognizing learning based on relations at a distance. The paper defines space as a network of both contiguous and non-contiguous relations of varying length, shape and duration, where knowing can involve all manner of spatial mobilizations, including placements of task teams in neutral spaces, face-to-face encounters, global networks held together by travel and virtual communications, flows of ideas and information through the supply chain, and trans-corporate thought experiments and symbolic rituals.     

Microbiological quality of tomatoes and peppers produced under the good agricultural practices protocol AGRO 2-1 & 2-2 in Crete, Greece

The efficiency of the good agricultural practices (GAP) protocol AGRO 2-1 & 2-2, in advancing microbiological-quality of tomatoes and peppers, was studied in greenhouses at Ierapetra, Crete, Greece. The 240 tested vegetables-samples, produced under AGRO 2-1 & 2-2, showed satisfactory quality: Listeria monocytogenes absent per 25 g; Escherichia coli < 20 Colony Forming Units per gram (CFU/g); total coliforms 4.37–4.68 log CFU/g; aerobic plate counts 5.78–5.92 log CFU/g. Based on actual results and practices evaluation, we conclude that AGRO 2-1 & 2-2 can reduce microbial hazards for consumers and furthermore can establish practices in compliance to basic Euro-Retailer-Produce GAP (EUREPGAP) requirements.     

Child Maltreatment, Parent Alcohol- and Drug-Related Problems, Polydrug Problems, and Parenting Practices: A Test of Gender Differences and Four Theoretical Perspectives.

The authors tested how adverse childhood experiences (child maltreatment and parent alcohol- and drug-related problems) and adult polydrug use (as a mediator) predict poor parenting in a community sample (237 mothers and 81 fathers). These relationships were framed within several theoretical perspectives, including observational learning, impaired functioning, self-medication, and parentification-pseudomaturity. Structural models revealed that child maltreatment predicted poor parenting practices among mothers. Parent alcohol- and drug-related problems had an indirect detrimental influence on mothers' parenting and practices through self-drug problems. Among fathers, emotional neglect experienced as a child predicted lack of parental warmth more parental neglect, and sexual abuse experienced as a child predicted a rejecting style of parenting.

How to Psychoanalyze a Robot: Unconscious Cognition and the Evolution of Intentionality1

According to a common philosophical distinction, the `original' intentionality, or `aboutness' possessed by our thoughts, beliefs and desires, is categorically different from the `derived' intentionality manifested in some of our artifacts –- our words, books and pictures, for example. Those making the distinction claim that the intentionality of our artifacts is `parasitic' on the `genuine' intentionality to be found in members of the former class of things. In Kinds of Minds: Toward an Understanding of Consciousness, Daniel Dennett criticizes that claim and the distinction it rests on, and seeks to show that ``metaphysically original intentionality' is illusory by working out the implications he sees in the practical possibility of a certain type of robot, i.e., one that generates `utterances' which are `inscrutable to the robot's designers' so that we, and they, must consult the robot to discover the meaning of its utterances. I argue that the implications Dennett finds are erroneous, regardless of whether such a robot is possible, and therefore that the real existence of metaphysically original intentionality has not been undermined by the possibility of the robot Dennett describes.     

Consistent practices in artifact-mediated collaboration

The design of collaborative representations faces a challenge in integrating theoretical communication models with the context-sensitive and creative practices of human interaction. This paper presents results from a study that identified multiple, invariant communicative practices in how dyads appropriated flexible, paper-based media in discussions of wicked problems. These invariants, identified across media, participants and topics are a promising first step towards creating an abstract model for design that connects representational affordances and communicative functions. The authors identify areas where this model may challenge conventional design wisdom and discuss directions for further research.     

Reconceptualizing classroom-based research in computers and composition

In this article, Webb maps out three dominant forms of research that have been undertaken in the field of computers and composition—theoretical, case studies, and limited quantitative. She then identifies a fourth mode that has begun to appear—a multimodal approach. Arguing for ways in which this method could help us answer research questions that have been previously unanswerable by other research methods, she calls for the field to reconsider incorporating this multimodal approach more within our research studies.
