Relativistic Ab initio Study On PtF and HePtF

The electronic structures and spectroscopic constants of the first three low-lying electronic states (Omega = 1/2, 3/2, and 5/2) of the linear HePtF complex were investigated by highly accurate relativistic ab initio methods, in which the spin-orbit coupling was taken into account, and compared with the results of PtF. It shows that the complex is significantly different from the typical van der Waals systems because of short He-Pt bond distances (1.80 similar to 1.87 angstrom), large He-Pt stretching frequencies (500 similar to 600 cm(-1)), considerable binding energies (1400 similar to 2500 cm(-1) with corrections), and a small electron transfer from helium (about 0.06). However, the topological analysis of the electron density distribution indicates that there is strong van der Waals interaction in the He-Pt bond instead of weak covalent one.Welch Foundation F-100Chemistr

Chaps Summary for South Dakota, 1991

Calving distribution and calf performance data were summarized from the CHAPS (Cow Herd Appraisal of Performance Software) analyses of 61 South Dakota cow herds. CHAPS uses beef cow weaning weight records to calculate adjusted 205-day weights and ratios, keep lifetime production records on cows, calculate Most Probable Producing Ability estimates for cows, produce a sire summary and analyze production according to cow age and 21 -day calving periods. The 1991 summary represents 6,196 cows for an average of 102 cows per herd. The herds ranged in size from 19 to 277 head. The average midpoint of the calving season for these herds was April 9. The average actual birth and weaning weights were 78.8 and 507.0 Ib, respectively, with the average age at weaning 205.3 days. Overall, 82.8% of the females calved by day 42 of their respective calving seasons, although there was considerable disparity in the percent calved by day 42 between the HIGH and LOW (92.9 vs 69.7%) calving distribution herds. This difference is important since actual weaning weights declined 35 to 60 Ib for each 21 days later that calves were born. In addition to these data for the state summary, CHAPS provides valuable information for making within herd selection and management decisions

Evaluating Cow Herd Productivity with CHAPS

CHAPS (Cow Herd Appraisal Performance Software) provides valuable performance information to use in: 1) selecting replacements, 2) making culling decisions, 3) evaluating bull performance, 4) evaluating reproductive efficiency, and 5) trouble-shooting the herd for management and reproductive problems. CHAPS does a lot more than the typical performance evaluation function of adjusting weaning and yearling weights and calculating ratios. In addition, the program prints: 1) a lifetime history of each cow’s performance, 2) a sire summary, 3) a Most Probable Producing Ability (MPPA) genetic evaluation for each cow, 4) a herd reproductive analysis, 5) a calving distribution chart, 6) a summary of weaning weight performance by crossbred cow type, and 7) a history of when and why cows were culled from the herd

The Effects of Environmental Modifications and Visual Supports in the Home on Engagement and Challenging Behaviors in Children with Autism

The purpose of this study was to determine the impact on engagement and challenging behaviors in young children with autism spectrum disorder (ASD) under two treatment conditions: 1) physical modifications to the home environment, and 2) physical modifications plus visual supports in the home environment. Treatment conditions were implemented in the child\u27s home environment with parents serving as interventionist. A single-subject nonconcurrent baseline design was used across three male participants: ages 3 years, 2 months; 4 years, 4 months; and 4 years, 11 months. The study included four to five baseline sessions, six to nine sessions in Treatment 1, six to nine sessions in Treatment 2 and two follow-up sessions per participant. During Treatment 1, modifications were made to each child\u27s environment (e.g., decreasing clutter, organizing playthings, and/or establishing a defined play space). Parent awareness training regarding the change was provided, and data was collected using the Individual Child Engagement Record-Revised (Kishida, Kemp, & Carter, 2008) and the Challenging Behavior Record (researcher developed) during play and/or daily routines with the child\u27s parent. During Treatment 2, visual supports were added to the modified environment to add structure and visual clarity (e.g., choice boards and how to boards ). Parent awareness training regarding the change was provided, and data was collected using the Individual Child Engagement Record-Revised (Kishida et al., 2008) and the Challenging Behavior Record during play and/or daily routines with the child\u27s parent. Based on the findings of the study, active engagement increased and challenging behaviors decreased following modifications in the home for three young children with autism. In regards to engagement across Treatment 1 and Treatment 2, children demonstrated active engagement with a mean of 62%, 76.89%, and 74.41% from a baseline of 1.75%, 15.75%, and 14.6%, respectively. In regards to challenging behaviors, across Treatment 1 and Treatment 2, children had fewer behaviors that interfered with engagement with a mean of 13.3%, 8.15% and 13.32%, from a baseline of 75%, 27.75%, and 49.2%, respectively. The overall results indicated significant positive effects from the use of physical modifications and physical modifications plus visual support in increasing engagement and decreasing challenging behaviors

Impacts of Types on Feed and Market Requirements

So you want to make them bigger! Or, do you want to add some milk to your cow herd? Improvements in these and other traits offer opportunities to increase production through higher weaning weights. However, the increased outputs are accompanied by increased feed and management inputs. Available research indicates that the increased production may or may not outweigh the increased inputs. Mature cow size and level of milk production are typically the factors considered when changes in cattle type are discussed. Numerous research studies have been conducted to evaluate the effects of these factors on biological and economic efficiency. In these studies, biological efficiency varied widely as conditions changed from study to study. The bottom line was that no one type, breed or kind worked best under all conditions. In fact, when biological efficiency was measured as the total energy required by a cow and calf to produce a pound of edible beef, there were virtually no significant differences noted among the breeds or types. Economic efficiency has varied according to the resources available. When an abundant supply of high quality feed is available, the larger, heavier milking cow has generally been more profitable. However, when the feed supply is restricted below the level needed to maintain high reproductive rates in these larger, high producing cattle, the smaller cow with somewhat lower milking ability generally becomes the more economically efficient

Community College Department Chairs\u27 Leadership Styles and Faculty Utilization of Instructional Technology

This study explores the relationship between faculty utilization of instructional technology and the leadership style of mathematics and English academic department chairpersons in associate degree-granting community colleges in the states of Maryland, Pennsylvania, and Virginia. The degree to which instructional technology was utilized in teaching courses was determined through self reporting surveys answered via mail by the selected faculty and chairs in the study. The academic department chairpersons in mathematics and English departments at the selected community colleges were rated by their faculty to determine their leadership style, using the Bolman and Deal Leadership Orientations survey. The leadership styles consisted of no-, single-, paired-, and multi-frame styles and were determined based on the number of frames (structural, human resource, political, symbolic) each chair was perceived by their faculty to use. Patterns of instructional technology utilization of faculty were analyzed by leadership style of their department chair in association with the variables of academic discipline, gender, size of academic department, and length of time as department chair

Love And Education In Plato\u27s Symposium

This paper seeks to illuminate the significance of Socrates\u27 entrance into a series of speeches by exploring the connection between love and learning in Plato\u27s Symposium. We begin by presenting historical and social contexts relevant to the dialogue and its author. We then turn to the dialogue, outlining the fundamental components of each speech and, moreover, analyzing each speech with the aim of eliciting educational implications which are later highlighted and expanded on by Socrates. We examine these pedagogical connotations through a thorough investigation of each speech, keeping a keen eye on Socrates. We approach our examination of Socrates’ speech in two key ways. The first is to examine how the educational implications found within the earlier speeches are later acknowledged and expanded on by Socrates. Furthermore, we also examine the way in which Socrates forms careful alterations of the previous speakers’ assertations to provide them with new meanings. Second, we examine Socrates\u27 approach in contrast with the prior speeches. In our examination of Socrates’ speech, we find that the structure of Socrates\u27 speech sharply contrasts with the overall narrative formatting of the prior speeches and the dialogue as a whole. We argue that Plato deliberately emphasizes Socrates\u27 approach by constructing a structure that contrasts with previous speeches. For further support of our interpretation, we turn to additional Platonic dialogues with the intent of gaining further insight into his educational approach.https://scholarworks.moreheadstate.edu/celebration_posters_2022/1029/thumbnail.jp

A new parameterization of an empirical model for wind/ocean scatterometry

The power law form of the SEASAT A Scatterometer System (SASS) empirical backscatter-to-wind model function does not uniformly meet the instrument performance over the range 4 to 24 /ms. Analysis indicates that the horizontal polarization (H-Pol) and vertical polarization (V-Pol) components of the benchmark SASS1 model function yield self-consistent results only for a small mid-range of speeds at larger incidence angles, and for a somewhat larger range of speeds at smaller incidence angles. Comparison of SASS1 to in situ data over the Gulf of Alaska region further underscores the shortcomings of the power law form. Finally, a physically based empirical SASS model is proposed which corrects some of the deficiencies of power law models like SASS1. The new model allows the mutual determination of sea surface wind stress and wind speed in a consistent manner from SASS backscatter measurements

Emerging Dialogic Structures in Education Reform: An analysis of Urban Teachers’ Online Compositions

This paper contextualizes contemporary urban teachers’ online dissent in public discussions of education reform in relation to past educational crisis narratives to interpret recent shifts in the structure of education reform dialogue in the United States. It does so by examining the form and content of compositions in which teachers respond to education reform. The analysis is intended to describe the digitally mediated roles teachers are asserting in a complex public debate over the future of education in the United States. The structure and content of education reform discourse has often cast teachers in static roles, which inhibits their active participation in discussions of educational policy. Using Mikhail Bakhtin’s position that language choices serve to stifle and/or reinvigorate dialogue, we examine contributions to online discussions and debate composed ostensibly by urban teachers in response to dominant discourses. The data were analyzed with respect to discursive choices and grouped subsequently as themed arguments and rhetorical moves. We argue that teachers’ strategic responses to education reform challenge stifling truisms that seek to suspend discussion of all other factors besides teacher quality. Teachers’ critical digital compositions thus re-create critical, multi-voiced conversations in place of monologues about school improvement. The online, public compositions point to the dynamic structure of reform discourse that has the potential to benefit those currently faulted for a variety of social problems. Nurturing and even exploiting the dynamic potential of educational reform discourse can create opportunities for teachers, policymakers, and educational researchers to mutually inform one another’s shared interest in educational improvement
