(excerpt) Chlorochlamys chloroleucaria (Guenée) is a common moth of eastern North America, recorded from Nova Scotia south to Cuba and Mexico and as far west as Manitoba, the Black Hills of South Dakota, Wyoming and central Colorado (Boulder and El Paso counties) (Ferguson 1985)

Efficacy of a two-ingredient fumigant on Richardson's ground squirrel

In July 1981, efficacy data were obtained on a new two-ingredient gas cartridge by field testing against Richardson's ground squirrels (Spermophilus richardsonii) in a sagebrush-rangeland pasture. The gas cartridge contained 97 g of a sodium nitrate (65%) and charcoal (35%) mixture and upon ignition generated mainly carbon monoxide with a small quantity of carbon dioxide. We live-trapped 53 (24 male and 29 female) ground squirrels, equipped each with a 164 MHz radio transmitter, and then released each at the point of capture. Later we located each ground squirrel and treated its main burrow and all burrows within 3 m by inserting ignited gas cartridges. After treatment the location of each radio-equipped ground squirrel was plotted. Ground squirrels showing no movement were presumed dead; death was confirmed by burrow excavation. Success rate was 84% as 41 of 50 (18 males and 23 females) died (82%) and 8 survived (16%). The radio transmitter on 1 (2%) failed immediately after treatment. Efficacy was estimated at 83.7%, which exceeds the 70% minimum standard established by the EPA. Thirty-eight ground squirrels died in burrows at depths ranging from 7.6 to 132.1 cm (mean = 74.7 ± SE 5.2 cm), and 3 died in nests at depths ranging from 94.0 to 182.9 cm (mean = 133.0 ±SE 26.2 cm). Seven of the eight survivors were retrapped. Factors contributing to survival are discussed, including soil porosity and moisture content, as well as squirrel body weight. Recommendations for further testing are presented

Interaction Effects of Socioeconomic Status on Emerging Literacy and Literacy Skills among Pre-Kindergarten and Kindergarten Children: A Comparison Study

Socioeconomic differences in children’s reading and educational outcomes have been thoroughly documented throughout literature. Bobalik, Scarber, and Toon (2017) examined the link between socioeconomic status (SES) and classroom instruction on emerging literacy skills in pre-kindergarten children. The results supported the theory that children identified as belonging to a low socioeconomic status enter school with lower emerging literacy skills and benefit most from academic instruction; these children’s literacy skills substantially increased throughout the academic year, growing closer to those of their peers who were identified with a high socioeconomic status. The aim of the present study was to expand our understanding of the interaction effects of socioeconomic status and curriculum on emerging literacy and literacy skills by continuing the research into kindergarten. This study examined whether 1) differences in groups continued to grow closer to the mean or 2) the differences in groups became greater with the introduction of reading skills in kindergarten. Children (N=33) were recruited from a private school and a public school. The children from the public school who qualified for the Federal Poverty Guidelines for free/reduced lunch were assigned as having a low socioeconomic status, and children from the private school were assigned as having a high socioeconomic status. The Phonological Awareness Literacy Screening – K (PALS-K) was used to measure the literacy skills in the kindergarten children. Results of the study indicated that literacy scores between the socioeconomic groups were not significantly different at the kindergarten level, however differences between the mean scores of the pre-kindergarten and kindergarten groups were found to be significant

Reading Guidance: A Study Based on an Analysis of the Interests, Habits, and Abilities of a Selected Group of Ninth Grade Students at Horace Maynard High School

This study was an evaluation of efforts to stimulate and motivate the development and refinement of the attitudes and habits involved in the personal reading selections of ninth grade students. The specific purpose was to determine the extent to which reading interests can be elevated and broadened under a carefully planned reading guidance program. The guidance procedures used were based on an analysis of the reading interests and abilities of a selected group of students. The problem of this investigation was to determine the following: 1. Into what categories do the personal reading interests and reading abilities of these students fall? 2. What relationship do sex and intelligence have to reading interests and preferences? 3. To what extent does the home environment affect achievement in reading and the development of literary taste as reflected by the reading choices of the students? 4. As a result of the planned reading guidance program, is there evidence of broadened interests and elevated reading tastes in (a) the quantity of books read, (b) a wider range of subjects selected, and (c) the quality and maturity level of books chosen

A Commercial Apartment Complex

Within this project the similarities and differences of new and used heating, cooling, and plumbing systems and equipment will be compared and contrasted in depth. Doing so would help further knowledge and understanding of the design field and help to foster quicker decision making in an educated way. The questions to be answered are: in which stage of this project did the client have the best equipment (the high-end outcome) and why, in which stage did they have the cheapest equipment (the low-end outcome) and why, in which stage did they have the best equipment while also being cost efficient (the cost efficient outcome) and why, and how can an engineer give the best offer to a client to ensure their needs are met. The motivation for this work would be to truly learn the advantages and disadvantages of different systems and re-using or buying new equipment in order to give future clientele exactly what they need and are looking for. Hopefully this will lead to being a more productive employee, a better consulting engineer, and more likely to receive and volunteer for more projects where the equipment studied is used

Dynamics of collaborative work in global software development environment.

This study aims to explore the dynamics of collaborative work in global software development projects. The study explored the nature of collaboration, the patterns of collaborative behaviors in different tasks in computer science, and the impact of the tasks to the collaboration among students. Four different collaborative software development tasks were assigned to the globally distributes teams. The study used data from 230 students from five universities, namely Atilim University (Turkey), Middle East Technical University (Turkey), Universidad Tecnológica de Panamá (Panama), University of North Texas (US), and Middlesex University (UK). The findings involve the recommendations for building effective collaborative working environments and guidelines for building collaborative virtual communities

Beyond the Textbook: An Approach to Facilitating Student Understanding of Organizational Culture in Organizations

Organizational culture has been likened to an onion, an umbrella, sticky glue, and an iceberg. Due to the multifaceted nature of the subject matter, presenting and explaining this topic to students can be a daunting task. This article describes an assignment that allows students to discover and understand organizational culture by conducting a cultural analysis of organizations. Student groups collaboratively complete this assignment by locating a research site, administering a questionnaire, processing quantitative data using a statistical analysis software package, analyzing qualitative data using content analysis with analytic coding, developing a formal written report, and making an oral presentation to representatives of the organization under study. The various components of the exercise allow students to practice critical and reflective thinking skills, explore quantitative and qualitative research methods, refine written and oral communication skills, apply knowledge and skills from various software applications, and provide experience working in a team environment
