Cock-a-doodle-coop: An Architect’s Response to the Call of Chickens Needing Shelter in Appalachia
No full textIn both rural and urban areas of Appalachia, the sound of backyard chickens is getting louder, with more homeowners owning a family flock; however, suitable shelter is not always inherently available as most newcomers to chicken husbandry lack outbuildings. This paper intends to illustrate the necessary research, design, and construction of a modern chicken coop through an example project by the author, architect Chad Everhart. Before embarking on the journey into tending a flock of his own laying hens, Everhart had never eaten a fresh egg, much less touched a live chicken. Also, he had only worked with and designed for human clients; therefore, a substantial amount of research was conducted before developing a design or building a structure. From incorporating solar power to inventing a chicken toilet, readers will witness a unique intertwining of vernacular and modern design techniques while also understanding the continued value of outbuildings, even our technologically-advanced society
Family needs and TBI caregiver mental health in Guadalajara, Mexico
No full textBACKGROUND: Traumatic brain injury (TBI) is a leading cause of death in Mexico, and Mexican TBI caregivers have been shown to experience significant mental health problems and high levels of family needs. OBJECTIVE: This study investigated the associations between family needs and Mexican TBI caregiver mental health. METHODS: Ninety TBI caregivers from Guadalajara, Mexico completed measures assessing their own mental health (depression, anxiety, burden, satisfaction with life, and self-esteem) and family needs (physical health, informational, financial, social support, and household). RESULTS: Family health needs were uniquely associated with all indices of caregiver mental health, and household needs were uniquely associated with caregiver depression, burden, and anxiety. Additionally, social support needs were related to caregiver satisfaction with life, informational needs to burden, and financial needs to self-esteem. CONCLUSIONS: Interventions for TBI caregivers in Mexico-and likely in other global regions with high levels of familism-should include an emphasis on overall family health, the delineation of family roles regarding household responsibilities, the improvement of social support networks and the social presence of family members, and the provision of complete and relevant information regarding TBI. When these needs are more comprehensively met, caregiver mental health will likely improve. © 2014-IOS Press and the authors. All rights reserved
Persistence pays off: Sir Charles Oatley and the scanning electron microscope
No full textShortly after World War II, Sir Charles Oatley initiated research at the Cambridge University engineering laboratories on what has evolved into the modern scanning electron microscope. While much of the research was actually conducted by research students under Oatley's supervision, he continually provided ideas, resources, and encouragement. He then was instrumental in having this instrument commercialized. His students often continued in the field for some time, making contributions both to the instrument and to its applications that led to improved performance and wider acceptance. This article attempts to capture some of the accomplishments of Sir Charles Oatley as seen by those who worked closely with him. The author believes that Sir Charles deserves the title: "Father of the Modern Scanning Electron Microscope.

No full textOur aim was to present the Qol Quality of Life Assessment (Qol) tools which are currently used in clinical practice, their role and importance in the classification and management of asthma. We reviewed 6 questionnaires: 1) Child Health Survey for Asthma (CHSA) -Developed by the American Academy of Pediatrics; 2) Child Health Survey for Asthma-Child Version (CHSA-C) -Developed by the American Academy of Pediatrics; 3) Pediatric Asthma Quality of Life Questionnaire (PAQLQ) - Developed by E.F. Juniper; 4) Pediatric Asthma Caregiver Quality of Life Questionnaire (PACQLQ) - Developed by E.F. Juniper; 5) Pictorial Quality of Life Measure for Young Children With Asthma (Pictorial PAQLQ) -Developed by R.S. Everhart and B.H. Fiese; 6) Pediatric Quality of Life Inventory 3.0 Asthma Module (of the Pediatric Quality of Life Inventory) (Developed by J.W. Varni). Assessing health-related quality of life (HRQOL) can provide a significant and more comprehensive assessment of the impact of asthma on a child\u27s quality of life. Its (QoL) study and correct evaluation can be very useful for the proper management and prognosis of asthma. The impact of asthma on quality of life is different in different countries, which is determined by the cultural, social, psychosomatic, nutritional characteristics of the nation, therefore, validation of the instruments for assessing the quality of life of children with asthma in Georgia is necessary and important.ჩვენი მიზანი იყო წარმოგვედგინა დღეისათვის კლინიკურ პრაქტიკაში გამოყენებული პედიატრიული ასთმის ცხოვრების ხარისხის შეფასების ინსტრუმენტები, მათი როლი და მნიშვნელობა ასთმის კლასიფიკაციის და მართვის საკითხში. განვიხილეთ 6 კითხვარი: 1) ასთმის მქონე ბავშვების ჯანმრთელობის შეფასება, მოწოდებული ამერიკის პედიატრთა აკადემიის მიერ - Child Health Survey for Asthma (CHSA) developed by the American Academy of Pediatrics; 2) ბავშვთა ჯანმრთელობის კვლევა ასთმა-ბავშვის ვერსია - Child Health Survey for Asthma-Child Version (CHSA-C) developed by the American Academy of Pediatrics; 3) პედიატრიული ასთმის ცხოვრების ხარისხის კითხვარი - Pediatric Asthma Quality of Life Questionnaire (PAQLQ) - developed by E.F.

Introduction to property theory - the fundamental theorems
No full textThe market system consists of a price mechanism, built on the foundation of a system of property, and contract. In many developing, and transition economies, the market system functions poorly. In many cases, if not most, the malfunctioning is not simply in the price system (for example, anti-competitive activities), but in the underlying property system (such as contracts being breached, and externalities in the sense of transfers not covered by contracts). Economic theory tends to take the functioning of the system of property, and contract for granted, and focuses on the operation of the price mechanism. Property theory focuses on the underlying system of property, and contract. In this paper, the author inaugurates the mathematical treatment of property theory.In contrast with earlier work in"law and economics", and the"new institutional economics", this approach uses principles drawn from jurisprudence, and does not attempt to reduce"law"to"economics"in the sense of efficiency considerations, such as the minimization of transaction costs. The main results are the two fundamental theorems of property theory that are analogous to the two fundamental theorems of price theory that, in essence, state that: 1) A competitive equilibrium is Pareto optimal. 2) Given a Pareto optimal state, there exists a set of prices such, that a competitive equilibrium at those prices would realize that Pareto optimal state.Environmental Economics&Policies,Labor Policies,Banks&Banking Reform,Municipal Housing and Land,Economic Theory&Research,Environmental Economics&Policies,Banks&Banking Reform,Economic Theory&Research,Municipal Housing and Land,Land and Real Estate Development
RB56-180 False Smut of Buffalograss
No full textFalse smut of buffalograss, Buchloe dactyloides (Nutt.) Engelm., caused by Cercospora seminalis Ell. & Ev. is a disease that destroys the unfertilized ovary. The disease was first reported by J. B. Ellis and B. M. Everhart in 1888. They gave only a brief description of the disease and named the causal fungus Cercospora seminalis. The origin of the term false smut is unknown to the author, but it so descriptively fits the general appearances of the disease that one readily understands its usage. The following studies were conducted from 1950 to 1954

Analytical Models in Electron Backscattering
No full textThe different aspects of electron backscattering from solid films are calculated in terms of simple analytical models for thin films and bulk targets, for normal and oblique incidence. Well-known models regard only one scattering aspect, e.g.: single Rutherford scattering by Everhart\u27s model, diffusion from a point source by Archard\u27s model, diffusion from sources continuously distributed over the depth of the target by Thümmel\u27s model. A few analytical models have been developed recently regarding single scattering and continuous diffusion, e.g. by Werner and by the author. These models allow us to calculate analytically the backscattering coefficient for bulk targets versus atomic number, for thin films versus thickness and incident electron energy, the angular intensity distribution, the total and angular energy distributions, and the surface density distribution of backscattered electrons. The numerical results of these models are compared with experimental results thus revealing the limits of the present models
