Current needs and response to suicidal behavior at the elementary school level: A survey of Virginia school psychologists

While minimal information on suicidal behavior at the elementary school level is available, a review of the existing literature demonstrates the erroneous belief that children lack the developmental maturity to understand the concept of death and suicide. To better understand prevalence rates of suicidal behavior in elementary school-aged children, interventions offered to those children, reported levels of practitioner competence, and overall preparedness of elementary school personnel in appropriately addressing suicidal behavior demonstrated by their students, the researcher surveyed 155 Virginia school psychologists. Results from the online survey revealed that while suicidal behavior in elementary school-aged students is rare, school-based professionals do believe that these students are at-risk for experiencing or demonstrating such behavior. Furthermore, school psychologists largely depend on school counselors to lead intervention efforts and communicate valuable information with them. While there are many needs in elementary schools, Virginia school psychologists have expressed the need for additional training opportunities in addition to establishing strong crisis response plans to respond to concerns as soon as possible

International elementary schools and interrupted students : a study of curriculum, pedagogically-engaged time and reading development

Includes bibliographical references (p. 130-142).This dissertation is concerned with the question of how reading development is influenced by the increase of pedagogically-engaged time amongst interrupted students within a particular curriculum. The study arose from observations that students of an interrupted educational background seemed to be achieving at a lower reading level than uninterrupted students - and thus, the study sought to establish the possible reasons and remedies for this problem. This study was primarily located at the American International School of Cape Town (AISCT), Cape Town, South Africa; and secondarily located at the Washington International School, Washington, D.C., United States of America

Finite element models of wire rope for vibration analysis

The usefulness of wire rope in shock and vibration isolation is briefly reviewed and its modeling for the purpose of vibration analysis is addressed. A model of a nominally straight segment of wire rope is described in which the rope structure is represented by a maiden, or central, strand of wire with one (or more) strand(s) wrapped around it in a helix (helices). The individual strands are modeled using finite elements and MSC NASTRAN. Small linear segments of each wire are modeled mathematically by dividing them lengthwise into triangular prisms representing each prism by a solid NASTRAN element. To model pretensioning and allow for extraction of internal force information from the NASTRAN model, the wound strands are connected to the maiden strand and each other using spring (scalar elastic) elements. Mode shapes for a length of wire rope with one and fixed to a moving base and the other attached to a point mass, are presented. The use of the NASTRAN derived mode shapes to approximate internal normal forces in equations of motion for vibration analyses is considered

Initial investigations into the damping characteristics of wire rope vibration isolators

Passive dampers composed of coils of multi-strand wire rope are investigated. Analytical results range from those produced by complex NASTRAN models to those of a Coulomb damping model with variable friction force. The latter agrees well with experiment. The Coulomb model is also utilized to generate hysteresis loops. Various other models related to early experimental investigations are described. Significant closed-form static solutions for physical properties of single-and multi-strand wire ropes are developed for certain specific geometries and loading conditions. NASTRAN models concentrate on model generation and mode shapes of 2-strand and 7-strand straight wire ropes with interfacial forces

Vaccines against toxoplasma gondii : challenges and opportunities

Development of vaccines against Toxoplasma gondii infection in humans is of high priority, given the high burden of disease in some areas of the world like South America, and the lack of effective drugs with few adverse effects. Rodent models have been used in research on vaccines against T. gondii over the past decades. However, regardless of the vaccine construct, the vaccines have not been able to induce protective immunity when the organism is challenged with T. gondii, either directly or via a vector. Only a few live, attenuated T. gondii strains used for immunization have been able to confer protective immunity, which is measured by a lack of tissue cysts after challenge. Furthermore, challenge with low virulence strains, especially strains with genotype II, will probably be insufficient to provide protection against the more virulent T. gondii strains, such as those with genotypes I or II, or those genotypes from South America not belonging to genotype I, II or III. Future studies should use animal models besides rodents, and challenges should be performed with at least one genotype II T. gondii and one of the more virulent genotypes. Endpoints like maternal-foetal transmission and prevention of eye disease are important in addition to the traditional endpoint of survival or reduction in numbers of brain cysts after challenge

Sarampo: idade ótima e número de doses recomendadas para a vacinação no Brasil

Este estudo foi inicialmente conduzido em população adulta normal, compreendendo doadores de Banco de Sangue, estudantes universitários e parturientes, totalizando 889 indivíduos. Foi observado que cerca de 87% desta população apresentava anticorpos específicos para o sarampo, e que o mesmo porcentual de positividade observado nas gestantes, foi encontrado nos seus respectivos conceptos dada a passagem transplacentária dos anticorpos maternos. Foi verificado o declínio desses anticorpos após o 4.° mês, do recém-nato. Os resultados à vacinação contra o sarampo foi estudada em 1268 crianças divididas em três grupos: I) vacinadas aos 7 meses e revacinadas aos 15 meses; II) vacinadas aos 9 meses e III) vacinadas aos 7 meses e revacinadas aos 9 meses. Os resultados deste estudo indicam que apesar da resposta à vacinação ter sido mais eficiente no grupo de crianças maiores, é importante que se vacine aos 7 meses de idade, embora a porcentagem de soroconversão tenha sido de 50%. Esta medida deve ser levada em consideração, tendo em vista que a mortalidade por sarampo em crianças com menos de 1 ano representa a metade dos óbitos pela doença. Foi verificado que após a aplicação da 2.° dose, não houve diferença quanto à soroconversão, tanto no grupo revacinado 2 meses ou 8 meses após a 1.º dose da vacina. Portanto, a vacinação aos 7 meses é necessária, visando diminuir a mortalidade e a morbidade dentro do 1.º ano de vida, e a revacinação aos 9 meses, a fim de imunizar as crianças não beneficiadas com a 1.ª dose

\u3cem\u3eAll the Pretty Horses\u3c/em\u3e: Cormac McCarthy’s Reading of \u3cem\u3eFor Whom the Bell Tolls\u3c/em\u3e

Compares All the Pretty Horses (1992) to For Whom the Bell Tolls, contending that the bell tolling “at the beginning of McCarthy’s novel is the writer’s homage to his predecessor.” Examines similarities in theme, character, and situation, noting that at times McCarthy revises and corrects Hemingway. Focuses on Robert Jordan and John Grady Cole as code heroes, and discusses the earlier cowboy code. Concludes with a list of other narrative parallels
