Reframing competitive critical analyses: An argument for education-application based methods for speech writing in CA and Rhetorical Criticism
This project offers a contemporary exemplar that students and coaches in competitive speech, specifically in the events of rhetorical criticism or communication analysis can use to help reframe traditional notions or methods of how to write a speech for competition. I contend that the event in competition has become too âcookie-cutterâ and devoid of innovation or âthinking outside the box,â which can limit the educational experience for our students. Thus, this project begins as a full critical analysis employing the theoretical framework of public memory and follows with a discussion of how a student in competitive speech could approach the event with a broader and more open notion of how to conduct an analysis. Finally, I offer suggestions to coaches and teachers in the event or the classroom for rhetorical criticism about how to guide students towards a more scholarly understanding of critical investigation and provide an exemplar that begins to re-frame the writing process of rhetorical criticism
Neural Networks for Modeling and Control of Particle Accelerators
We describe some of the challenges of particle accelerator control, highlight
recent advances in neural network techniques, discuss some promising avenues
for incorporating neural networks into particle accelerator control systems,
and describe a neural network-based control system that is being developed for
resonance control of an RF electron gun at the Fermilab Accelerator Science and
Technology (FAST) facility, including initial experimental results from a
benchmark controller.Comment: 21 p
Observed Reductions in School Bullying, Nonbullying Aggression, and Destructive Bystander Behavior: A Longitudinal Evaluation
This study was a longitudinal extension of a random control trial of the Steps to Respect antibullying program. Students in Grades 3â5 were surveyed (n = 624) and observed on the playground (n = 360). Growth curve models of intervention students showed 2-year declines in playground bullying, victimization, nonbullying aggression, destructive bystander, and argumentative behavior. Grade-equivalent contrasts indicated group differences in all problem behaviors. Problem behaviors in the control group increased or remained stable across grade. Intervention group students reported less difficulty responding assertively to bullying compared with control students. Within both groups, older students perceived themselves to be more aggressive and less frequently victimized than younger students. Methodological issues posed by inconsistencies between self-reported and observed behavior are discussed
Walking the Talk in Bullying Prevention: Teacher Implementation Variables Related to Initial Impact of the \u27Steps to Respect\u27 Program
This study examined relationships between teacher implementation of a comprehensive bullying prevention program and student outcomes. Implementation in third- through sixth-grade classrooms (N = 36) was measured by observation and teacher report. Student outcomes were measured by student surveys and teacher ratings of peer social skills (N = 549) and observations of playground behaviors (n = 298). Multilevel modeling showed that teacher coaching of students involved in bullying was associated with less observed victimization and destructive bystander behavior among students engaged in these problems at pretest, and less observed aggression among ïŹfth- and sixth-grade students. Support for skill generalization related to reductions in observed aggression and victimization among older students. Adherence to lessons was associated with higher ratings of peer social skills. Quality of lesson instruction corresponded to greater self-reported victimization, as well as more perceived difïŹculty responding assertively to bullying. Implications for school-based practice and future research directions are discussed
Reducing Playground Bullying and Supporting Beliefs: An Experimental Trial of the \u27Steps to Respect\u27 Program
Six schools were randomly assigned to a multilevel bullying intervention or a control condition. Children in Grades 3â6 (N = 1,023) completed pre- and posttest surveys of behaviors and beliefs and were rated by teachers. Observers coded playground behavior of a random subsample (n = 544). Hierarchical analyses of changes in playground behavior revealed declines in bullying and argumentative behavior among intervention-group children relative to control-group children, increases in agreeable interactions, and a trend toward reduced destructive bystander behavior. Those in the intervention group reported enhanced bystander responsibility, greater perceived adult responsiveness, and less acceptance of bullying/aggression than those in the control group. Self-reported aggression did not differ between the groups. Implications for future research on the development and prevention of bullying are discussed
Refining victimsâ self-reports on bullying:Assessing frequency, intensity, power imbalance, and goal-directedness
Bullying can be differentiated from other types of peer aggression by four key characteristics: frequency, intensity, power imbalance, and goalâdirectedness. Existing instruments, however, usually assess the presence of these characteristics implicitly. Can selfâreport instruments be refined using additional questions that assess each characteristic? We examined (a) what proportion of children classified as victims by the commonly used Revised Olweusâ bully/victim questionnaire (BVQ) also experienced the characteristics of bullying, and (b) the extent to which the presence of the characteristics was associated with emotional (affect, school, and classroom wellâbeing), relational (friendship, defending), and social status (popularity, rejection) adjustment correlates among victims. Using data from 1,738 students (Mage = 10.6; grades 5â8), including 138 victims according to the BVQ, the results showed that 43.1% of the children who were classified as victims by BVQ experienced all the four characteristics of bullying. Frequency ratings of victimization did not capture experiences that involved a power imbalance. Victims who reported all four key characteristics had greater emotional, relational, and social status problems than victims who did not report all characteristics. Thus, researchers who focus on victimization for diagnostic and prevention purposes can enrich selfâreport measurements of bullying victimization by adding questions that assess the characteristics explicitly
Howard walnut trees can be brought into bearing without annual pruning
In traditionally managed Howard walnut orchards, trees are pruned annually during
the orchard development phase, an expensive operation in terms of labor and prunings
disposal costs. Our observations and some prior research by others had suggested that
pruning may not be necessary in walnut. In a trial of pruned and unpruned hedgerow
trees over 8 years, beginning a year after planting, we documented canopy growth,
tree height, yield and nut quality characteristics and also the effects of fruit removal.
Pruning altered canopy shape but did not lead to increases in canopy development,
yield or nut quality. Although fruit removal stimulated more vegetative growth in
both the pruned and unpruned treatments, fruit removal did not result in an increase
in midday canopy photosynthetically active radiation interception or cumulative yield
when fruit removal was stopped after year 4. After 8 years, there were no significant
differences in tree height, nut quality or cumulative yield among any of the treatments,
which suggests that not pruning young Howard orchards could provide a net benefit
to growers
