Odonata at a Small Woodland Pond in Southern Illinois

A survey of the adult odonate fauna of a small woodland pond in Pope County, Illinois, was conducted during 1983--·1984. Twenty-four species were collected including Aeshna mutata and Anax longipes. In addition, Libellula vibrans was collected in 1982, and Aeshna sp. (probably u. umbrosa) observed the same year but not collected

Experiences with and interpretation of standard test methods of building energy analysis tools

The authors separately apply ANSI/ASHRAE Standard 140-2001 to the simulation program TRNSYS, comparing not only their results but the differences in their simulation assumptions and in their interpretations of the Standard's test cases. Results of the application are presented for all three authors, showing that there is a significant amount of leeway within a complex simulation tool such asTRNSYS for users of different backgrounds to apply their own common simulating practices and still fall comfortably within the range of acceptability specified by such Standards. Included in the application results are results of sensitivity tests that demonstrate the relative importance of assumption differences

Redetermination of parameters for semi-empirical model for spallogenic He and Ne in chondrites

A semi-empirical model described previously satisfactorily reproduced a number of shielding-dependent variations in the relative production rates of spallogenic He and Ne in chondrites. However, data for cores of the Keyes and St. Severin meteorites showed a subsurface build-up in He-3 which was not predicted with the original model parameters and the model was not pursued. Renewed interest in the preatmospheric size of meteorites, spurred in part by the desirability of understanding the exposure history of the SNC meteorites, justifies redetermination of model parameters

Combining different validation techniques for continuous software improvement - Implications in the development of TRNSYS 16

Validation using published, high quality test suites can serve to identify different problems in simulation software: modeling and coding errors, missing features, frequent sources of user confusion. This paper discusses the application of different published validation procedures during the development of a new TRNSYS version: BESTEST/ASHRAE 140 (Building envelope), HVAC BESTEST (mechanical systems) and IEA ECBCS Annex 21 / SHC Task 12 empirical validation (performance of a test cell with a very simple mechanical system). It is shown that each validation suite has allowed to identify different types of problems. Those validation tools were also used to diagnose and fix some of the identified problems, and to assess the influence of code modifications. The paper also discusses some limitations of the selected validation tools

Converging on a recommended set of interpretations and assumptions in applying standard tests to energy analysis tools

The authors, having individually applied ANSI/ASHRAE Standard 140-2001 to the simulation program TRNSYS in a previous project, compare their results, simulation assumptions, and interpretations of the Standard's test cases to arrive at a conformed set of recommended practices. Sensitivities to individual assumptions are investigated and results of applying the conformed set of assumptions are presented

Attributions others assign to depressed individuals and their relationship to severity of depressive symptoms, amount of contact, and familiarity with depressed individuals

While there has been valuable research critical for furthering our understanding of how an individual\u27s social network affects recovery from depression, we need to know more about the interplay of other people\u27s attributions and their relationships with depressed individuals that may impact recovery from the disorder. This research investigated causal and controllability attributions that others assign to individuals with depression by distributing a questionnaire to faculty and administrative staff at Eastern Michigan University to obtain ratings of attributions for depression. The level of intimacy within a relationship and the severity of depression were related to others\u27 beliefs about the controllability of depressive symptoms. Exploring these relationships may expand our understanding of how and when specific attributions begin and how they change. This information may be useful in developing treatments for depression that not only help the individual suffering with the disorder but also others around the individual who are affected

An Investigation of the Communication Skills and Communication Needs of Academic and Civil Service Administrators

This article presents a study which is designed to determine the level of importance of communication skills for academic and civil service administrators in an academic setting. Two samples of administrators participated in the study, including 120 academic administrators and 120 civil service administrators from a midwestern university. The questionnaires were sent through campus mail to random samples of academic administrators and civil service administrators. Exploratory analyses were completed to determine if differences existed between genders. The results basically show that gender is not a good discriminating variable because of the high within group variances and limited between group variances. Communication activities dominate the world of work of academic and civil service administrators in an academic setting. Previous research indicates this is true for most professional groups

Simulation synergy : expanding TRNSYS capabilities and usability

Developers of simulation packages are now able to take advantage of the increase in available desktop computing power to expand the capabilities and usability of their programs. This paper will illustrate these opportunities by discussing the different techniques the developers of the TRNSYS software package have used to try and create a synergy between TRNSYS and external programs and between the developers and users of the program

Parental attributions concerning the causes and controllability of adolescent depression

The primary purpose of this study was to explore the relationship between parental attributions concerning adolescent depression and levels of negative expressed emotion (EE) within the home by breaking down attributional beliefs into two dimensions: the etiology of the disorder and the controllability of the symptoms. This study included 154 parents of adolescents who filled out an online survey. Participants were predominantly female and identified themselves as White/non-Hispanic. Among the teens, each gender was relatively well-represented. Mean age of respondents was 44.7, and mean age of the adolescents was 16.0. Of the entire sample, 101 were identified as the clinical group (having a teen with depression). The questionnaire included a section developed to measure specific attributions related to depression, the Children’s Depression Inventory – Parent Version (Kovacs, 2002), and the Level of Expressed Emotion Scale (Cole & Kazarian, 1988). Results showed that controllability attributions are related to measures of expressed emotion (p \u3c .01), while beliefs about causality had mixed results. It is suggested by this study that beliefs regarding controllability and causal beliefs may be less related than previous researchers suspected, and controllability beliefs may be more salient to theories of EE
