Infrastructure Management Information System Framework Requirements for Disasters

A three-tiered, enterprise, geographic information system architecture offers a robust, efficient, and secure platform to potentially revolutionize disaster management by enabling support of all of the phases of governmental activity that must occur before, during, and after a disaster. Presently, both publicly and privately initiated, computer-based systems designed for disaster management cannot meet the real-time data access and analysis needs at crucial stages, especially those occurring during an actual disaster. Impediments are reflective of the proprietary, stand alone, and segregated nature of current systems. This paper proposes an integrated, infrastructure management information system as a reliable and effective alternative. Issues related to sharing data, customizing applications, supporting multiple data formats, querying visually, facilitating ubiquitous computing, and upgrading are all addressed. Achieving maximum flexibility and capacity in a disaster management system relies upon recent advances in the following areas: (1) standardized data specifications; (2) middleware services; and (3) Web-enabled, distributed computing. Key resources in designing and implementing such an arrangement are prototyped in a system that was initially designed for addressing disaster management of urban explosions. The critical details of that system are presented herein.     

Idiom literality judgments in younger and older adults: Age-related effects in resolving semantic interference.

To study age effects in the resolution of idiomatic semantic ambiguity, we focus on decomposability, the extent to which a literal reading of an idiom's words shares meaning with its figurative interpretation. Younger and older adults judged whether decomposable and nondecomposable idioms and nonidioms had a literal interpretation. Older adults were slower at making literality judgments and more sensitive to conflicts between literal and figurative meanings. The results support claims of decompositional analysis of idioms during later processing stages and of obligatory activation of figurative meanings. They also lend support to research that has shown age-related effects in ambiguity resolution. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Overview: For crying out loud--dangers and opportunities of communicating in the public domain.

Communication often extends into the public domain, inviting "eavesdropping" and other forms of exploitation by other species. Conflict is frequently the result, although interspecific communication can be mutually beneficial even when interests conflict fundamentally, such as between predator and prey. However, the most complex communication systems are likely to involve species with mutual rather than with conflicting interests. When interests do conflict, exploitation of the communication systems of others may impose high costs on signalers and select for signals that are less exploitable. Other costs of communication in the public domain arise from "mistakes" (e.g., mating with the wrong species) and select for more species-specific signal structure. The articles in this section illustrate the complexity of interspecific communication and yield important insights into the dynamic nature of communication systems.

Activated carbon for mercury control: Implications for fly ash management

As more utilities begin to use activated carbon injection (ACI) for mercury control, the potential for the presence of elevated concentrations of mercury, other air toxic elements, and activated carbon to impact fly ash management needs to be evaluated. Several Energy & Environmental Research Center (EERC) projects have allowed the collection of comparative baseline fly ash samples and associated fly ash–activated carbon (AC) samples from full-scale demonstrations of ACI for mercury emission control. These samples were evaluated for mercury and air toxic element content and mobility and for performance criteria to facilitate a better understanding of the impact of these components to specific utilization applications, including use as a mineral admixture in concrete. These data are compared with published data from samples collected at similar large-scale mercury emission control tests.     

Methylphenidate and baseball playing in ADHD children: Who's on first?

The effects of 0.3 and 0.6 mg/kg methylphenidate were analyzed in a double-blind, placebo-controlled, cross-over study in which 17 boys (ages 7.8–9.9 yrs) with attention deficit hyperactivity disorder (ADHD) played in baseball games. Drug effects were evaluated on children's attention during the game, as indictated by their on-task behavior on the field and their ability to answer questions about the status of the game at all times. Judgment during batting, batting skill during the game, and performance on skill drills prior to the game were also assessed as a function of medication. Results revealed that methylphenidate had a beneficial effect on attending during the game. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Children's understanding of verbal and facial display rules.

144 1st, 3rd, 5th, and 10th graders listened to 8 stories designed to elicit either prosocial or self-protective display rules. Ss were asked to predict and explain what the protagonists would say and what facial expressions the protagonists would make in response to the emotion-laden situations. Findings indicate that Ss' knowledge of how and when to control emotional displays increased between 1st and 5th grade but then leveled off. Ss understood verbal display rules better than facial display rules, and they understood prosocial display rules better than self-protective ones. They sometimes failed to realize when other people would wish to regulate their emotional expressions. Findings are discussed in terms of the socialization of emotional displays, particularly the greater pressure placed on children to control verbal expression more than facial expression and to learn more prosocial than self-protective display rules.

The classroom environment and students' reports of avoidance strategies in mathematics: A multimethod study.

The relation between the learning environment (e.g., students' perceptions of the classroom goal structure and teachers' instructional discourse) and students' reported use of avoidance strategies (self-handicapping, avoidance of help seeking) and preference to avoid novelty in mathematics was examined. Quantitative analyses indicated that students' reports of avoidance behaviors varied significantly among classrooms. A perceived emphasis on mastery goals in the classroom was positively related to lower reports of avoidance. Qualitative analyses revealed that teachers in high-mastery/low-avoidance and low-mastery/high-avoidance classrooms used distinctively different patterns of instructional and motivational discourse. High incidence of motivational support was uniquely characteristic of high-mastery/ low-avoidance classrooms, suggesting that mastery goals may include an affective component. Implications of the results for both theory and practice are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Mental health services for homeless mentally ill persons: Federal initiatives and current service trends.

Recent research suggests that approximately one third of the population of homeless single adults suffer from severe mental illnesses. Despite multiple health, mental health, and social welfare needs, this population is often unable to obtain necessary housing and community-based services. For this reason, since 1982, the National Institute of Mental Health (NIMH) has undertaken a number of federal initiatives to encourage research and assist states and localities in improving services focused on this vulnerable subgroup of the homeless population. This article describes the target population, NIMH research findings, and current mental health programs—with particular emphasis on two mental health programs established under the Stewart B. McKinney Homeless Assistance Act. Proposed future directions for federal research and evaluation efforts in this area are also discussed.

Pre- and postbirth antecedents of 2-year-old attention, capacity for relationships, and verbal expressiveness.

46 families were followed from midpregnancy to child age 2 yrs. At midpregnancy mothers were interviewed and completed the Wechsler Adult Intelligence Scale (WAIS) and the Minnesota Multiphasic Personality Inventory (MMPI). Various forms of data were collected at 1, 3, 6, 12, and 24 mo postbirth, including observations in the home and infant assessment, using the Bayley Scales of Infant Development. Results indicate that the pattern of antecedents and correlates differed as a function of the criteria chosen. Thus, the 2-yr-olds' attention was not significantly influenced by the concurrent parent stimulation of cognitive and verbal experiences, but the most impressive determinants consisted of 2 forms of early child behavior, 1-mo positive vocalization and 6-mo attention, as well as prebirth maternal IQ. By contrast, the 2-yr-olds' modulation of aggression was not only an integral part of a concurrent set of relationship variables but the significant antecedents stressed prebirth parent characteristics having a high potential for promoting a positive, emotionally responsive relationship with the child (warmth, adaptation–competence, husband–wife adaptation), whereas the postbirth antecedents were highlighted by parents responding successfully to the needs of an increasingly soothable infant.
