The Relationship between Attitudes, Knowledge, and Demographic Variables of High School Teachers Regarding Food Irradiation

ABSTRACT:  The purpose of this study was to use a validated instrument to determine the attitudes and knowledge of high school teachers regarding food irradiation, and to determine the correlations among their knowledge and attitudes and certain demographic variables. Knowledge and attitudes about food irradiation were measured in selected high school family and consumer sciences teachers ( n = 121) who taught Food and Nutrition, Food Science and Technology, and/or Food Production Management and Services, via a 24-item instrument with 6 factors. Results revealed these teachers held neutral to positive attitudes about the safety of irradiated foods, their perception of the risk of foodborne illness, and learning about food irradiation, and neutral to negative perceptions of their understanding of food irradiation and their competence to teach about it. These teachers had a moderate knowledge base regarding food irradiation. Teachers' attitudes regarding the safety of food irradiation were positively correlated with their perceived understanding of food irradiation, actual knowledge of it, and competence to teach about it. Their perceived understanding of food irradiation was positively correlated with competence to teach about it, knowledge, and attitudes toward the safety of food irradiation. The only demographic variable correlated with knowledge or attitudes was teachers' previous food irradiation educational experiences. These data suggest the importance of education for family and consumer sciences teachers concerning food irradiation.     

Temperament, emotion, and social interactive behavior in the strange situation: a component process analysis of attachment system functioning

This study examines the contributions of temperamentally and nontemperamentally based emotional reactions to the organization of social interactive behavior within the Strange Situation to better understand the emotional underpinnings of attachment system functioning. At 12 1/2 and 19 1/2 months, temperamental fear (assessed via maternal report) was related to independent per-episode dimensions of social interactive and distress behavior. Fear was moderately correlated with both distress and interactive dimensions at each age. Path-analytic models revealed that temperamental fear had direct effects on interactive behavior and also indirect effects mediated by preceding distress reactions. However, residualized measures of "context-specific" distress (with temperamental variance removed) were still highly consistent across Strange Situation episodes and also significantly predicted subsequent social interactive behavior; furthermore, stable distress reactions from 12 1/2 to 19 1/2 months significantly predicted concurrent stability in social interactive behavior. We discuss likely sources of "context-specific" emotional influences on Strange Situation behavior and also age-related differences in these findings.     

ADORNO AND THE BORDERS OF EXPERIENCE: THE SIGNIFICANCE OF THE NONIDENTICAL FOR A "DIFFERENT" THEORY OF BILDUNG

A bstract .  In this essay Christiane Thompson discusses the systematic outcomes of Theodor Adorno's philosophical work for a reworked theory of Bildung (an important term in the German tradition of philosophy and history of education). In his essay "Theory of Halbbildung ," Adorno revealed the inevitable failure of Bildung , on the one hand, and the necessity of Bildung (in view of a critique of society), on the other. After having exposed this contradiction, Thompson seeks to analyze Bildung 's systematic role by turning to Adorno's reflections on art and metaphysics. Adorno's concept of aesthetic experience hints at the possibility of a more genuine approach to Bildung and culture, one that makes the borders of our experience visible and, as a result, suggests a different relation to ourselves and to the world. She concludes by examining the critical dimensions of this different Bildung as well as its pedagogical relevance.     

Quantitative reasoning,complexity, and additive structures

Six fifth-grade children participated in a four-day teaching experiment on complex additively-structured problems, which was followed by in-depth interviews of individual children. The teaching experiment was meant to investigate children's difficulties in holding in mind at once situations in which one or more items played multiple roles. Two important difficulties were identified: (1) distinguishing between difference as the result of subtracting and difference as the amount by which one quantity exceeded another; and (2) indirect evaluation of an additive comparison. Sources of these difficulties, along with pedagogical and curricular recommendations for addressing them, are discussed.Research reported in this paper was supported by National Science Foundation Grants NO.

Emotional regulation and emotional development

Current neofunctionalist views of emotion underscore the biologically adaptive and psychologically constructive contributions of emotion to organized behavior, but little is known of the development of the emotional regulatory processes by which this is fostered. Emotional regulation refers to the extrinsic and intrinsic processes responsible for monitoring, evaluating, and modifying emotional reactions. This review provides a developmental outline of emotional regulation and its relation to emotional development throughout the life-span. The biological foundations of emotional self-regulation and individual differences in regulatory tendencies are summarized. Extrinsic influences on the early regulation of a child's emotion and their long-term significance are then discussed, including a parent's direct intervention strategies, selective reinforcement and modeling processes, affective induction, and the caregiver's ecological control of opportunity for heightened emotion and its management. Intrinsic contributors to the growth of emotional self-regulatory capacities include the emergence of language and cognitive skills, the child's growing emotional and self-understanding (and cognized strategies of emotional self-control), and the emergence of a theory of personal emotion in adolescence.     

Towards a sociocognitive model of progression in spoken English

Current approaches to oral assessment of English in English secondary schools tend to concentrate more on ‘confidence’ and ‘participation’ than on the quality of children's thinking. This undermines the rich possibilities in classroom talk for cognitive development. Behavioural assessment approaches deny the essentially cognitive character of spoken English. This paper compares two brief representative extracts from a larger data‐set of students engaged in small group debate on the subject of abortion. One group of students are hindered in their discussion by an inability to conceptualize abstractly. It is suggested that a formative assessment approach based on a model of cognitive progression such as Vygotsky's could enable all students to develop as speakers by encouraging their teachers to focus more explicitly on the development of the quality of thinking. A sociocognitive framework for conceptual progression could guide teachers in their interpretation of peer debate in order to develop the quality of students' understanding and argument. Building on the work of Newman, Griffin and Cole, and Torrance and Pryor, further research should be conducted into the ways in which formative teacher–student and student–student assessment dialogue might enhance students' ability to think through talk.     

User library service expectations in health science vs. other settings: a LibQUAL+ Study

Objectives: To explore how the library service expectations and perceptions of users might differ across health‐related libraries as against major research libraries not operating in a medical context; to determine whether users of medical libraries demand better library service quality, because the inability of users to access needed literature promptly may lead to a patient who cannot be properly diagnosed, or a diagnosis that cannot be properly treated. Methodology: We compared LibQUAL+® total and subscale scores across three groups of US, Canadian and British libraries for this purpose. Results: Anticipated differences in expectations for health as other library settings did not emerge. Conclusions: The expectations and perceptions are similar across different types of health science library settings, hospital and academic, and across other general research libraries.
