Maximum Dynamic Strength,Relative Dynamic Endurance,and Their Relationships

Abstract

Nine males and nine females were used as subjects to test the null hypothesis that there would be no significant differences between the performance of college age males and females on three motor tasks. Star tracing, tapping, and rotary pursuit were the tasks used under two conditions: (a) while looking at a mirror that would cause a reversal effect, and (b) under standard conditions without looking at a mirror. Results revealed no differences between males and females on the tasks performed without a mirror. However, the females performed significantly better on the same tasks while looking at a mirror.     

Placement and frequency of powerless talk and impression formation

Study One examined the influence of initial use of hesitations and hedges on evaluations of witnesses and their persuasiveness in a budget hearing context. Results indicate that the negative attributions generated by the use of powerless language cannot be overcome by subsequent use of powerful talk. Study Two examined the relationship between the frequency of powerless language use and impression formation. For award/character and dynamism a perceptual threshold appeared to operate. The results of both studies suggest that auditors are very sensitive to the influence of powerless talk in formal settings.     

What Is Measured Is Treasured: The Impact of the No Child Left Behind Act on Nonassessed Subjects

In this article, the author reports the results of a national survey taken by state assessment directors on the impact of No Child Left Behind on nonassessed subjects between the years 2001-5. Results indicate that during this time, statewide assessment of science and writing increased whereas it decreased in the social studies, arts and humanities, listening, and technology and computers. Four themes emerged when survey takers queried participants about the impact of No Child Left Behind on nonassessed subject areas. First, reduction of resources and time for nontested subject areas was evident. Second, curriculum integration of nontested subject areas into the tested subjects increased. Third, alignment of curriculum and assessment with state standards increased. Fourth, several state assessment directors relayed they observed no impact.     

Does food insecurity at home affect non-cognitive performance at school? A longitudinal analysis of elementary student classroom behavior

This paper estimates models of the transitional effects of food insecurity experiences on children's non-cognitive performance in school classrooms using a panel of 4710 elementary students enrolled in 1st, 3rd, and 5th grade (1999-2003). In addition to an extensive set of child and household-level characteristics, we use information on U.S. counties to control for potential confounding effects of the local economic and noneconomic environment on children's household transitions between states of food insecurity and food security. The time horizon of our analysis affords insight into factors underlying children's formation of non-cognitive skills and the efficiency of classroom-based educational production in elementary school. Overall, we find significant negative developmental effects for children with food insecurity at home; and that children experiencing an early transition from food insecurity in 1st grade to food security in 3rd grade have even larger impairments that persist through 5th grade.     

Intent-based diversification of web search results: metrics and algorithms

We study the problem of web search result diversification in the case where intent based relevance scores are available. A diversified search result will hopefully satisfy the information need of user-L.s who may have different intents. In this context, we first analyze the properties of an intent-based metric, ERR-IA, to measure relevance and diversity altogether. We argue that this is a better metric than some previously proposed intent aware metrics and show that it has a better correlation with abandonment rate. We then propose an algorithm to rerank web search results based on optimizing an objective function corresponding to this metric and evaluate it on shopping related queries.
