Investigating well-being and mental health in Queensland fire-fighters

This thesis used survey and interview methods to examine how organisational and interpersonal factors impact on the mental health of fire and rescue workers. It was the first published research to assess and predict multiple indicators of mental health; psychological distress, well-being, posttraumatic growth and posttraumatic stress disorder symptoms. The results provide valuable information for supporting fire and rescue workers through psychoeducation and proactive intervention programs.

RBAC与MAC在多级关系数据库中的综合模型

多级安全数据库的安全策略需要各种模型来表达,访问控制模型是其中之一.强制访问控制(MAC)模型保证多级数据库中的信息流动符合系统的安全策略.利用基于角色的访问控制(RBAC)来实现MAC能方便多级安全数据库的权限管理.提出了一种MAC与RBAC的综合模型,定义了多级角色与内部角色的概念,并给出了综合模型中经过修改后的操作,使得系统能自动地完成符合强制访问控制策略的用户权限的管理.该模型方便了管理员的权限管理,适合用户较多,安全层次比较复杂的多级关系数据库系统.最后给出了模型的部分实现机制.

Técnicas, procedimientos e instrumentos para realizar las adaptaciones curriculares.

Este trabajo pretende ayudar y facilitar al profesorado su tarea profesional, sugiriendo técnicas y procedimientos y proporcionando los instrumentos necesarios para elaborar Adaptaciones Curriculares Individualizadas (ACIs), materializarlas en un Documento Individual de Adaptación Curricular (DIAC) y posibilitar su aplicación. El volumen consta de dos partes y un disquete, que incluye todo el soporte informático. La primera establece el marco teórico de las adaptaciones; recoge reflexiones sobre conceptos previos a la realización de las ACIs y sobre otros contenidos relacionados con ellas. La segunda parte está dedicada a la puesta en práctica de su proceso de elaboración, fundamentando previamente cada uno de los instrumentos que se ofrecen: contenido de la evaluación psicopedagógica; determinación de las necesidades educativas especiales y propuesta curricular apropiada para las diferentes áreas y apoyo educativo y colaboración familiar.

Histological and morphometric comparisons of worker and queen mandibular glands of Melipona bicolor bicolor (Hymenoptera, Meliponini)

In the present investigation we analyzed both histology and area of secretory cells from workers, virgin and physogastric queen mandibular glands of Melipona bicolor bicolor Lepeletier. The histological differences observed include the number of vacuoles present in the cell cytoplasm and the quantity and distribution of the secretion. The morphometry results demonstrated the occurrence of significative differences in the cell area values that were related to the secretory cell activity level, which is higher in the physogastric queens. Worker and queen glands have histological patterns quite similar, but the morphometric data indicated cast-specific differences, as well as differences between the queens, which were related to the posture activity.

Prospective randomised comparison of diagnostic confidence and image quality with normal-dose and low-dose CT pulmonary angiography at various body weights.

OBJECTIVES To find a threshold body weight (BW) below 100 kg above which computed tomography pulmonary angiography (CTPA) using reduced radiation and a reduced contrast material (CM) dose provides significantly impaired quality and diagnostic confidence compared with standard-dose CTPA. METHODS In this prospectively randomised study of 501 patients with suspected pulmonary embolism and BW <100 kg, 246 were allocated into the low-dose group (80 kVp, 75 ml CM) and 255 into the normal-dose group (100 kVp, 100 ml CM). Contrast-to-noise ratio (CNR) in the pulmonary trunk was calculated. Two blinded chest radiologists independently evaluated subjective image quality and diagnostic confidence. Data were compared between the normal-dose and low-dose groups in five BW subgroups. RESULTS Vessel attenuation did not differ between the normal-dose and low-dose groups within each BW subgroup (P = 1.0). The CNR was higher with the normal-dose compared with the low-dose protocol (P < 0.006) in all BW subgroups except for the 90-99 kg subgroup (P = 0.812). Subjective image quality and diagnostic confidence did not differ between CT protocols in all subgroups (P between 0.960 and 1.0). CONCLUSIONS Subjective image quality and diagnostic confidence with 80 kVp CTPA is not different from normal-dose protocol in any BW group up to 100 kg. KEY POINTS • 80 kVp CTPA is safe in patients weighing <100 kg • Reduced radiation and iodine dose still provide high vessel attenuation • Image quality and diagnostic confidence with low-dose CTPA is good • Diagnostic confidence does not deteriorate in obese patients weighing <100 kg.

This layer is a georeferenced raster image of the historic paper map entitled: To David Stone and Peter Brown, Esq. : this first actual survey of the state of North Carolina taken by the subscribers is respectfully dedicated by their humble servants, Jona. Price and John Strother ; engraved by W. H. Harrison. It was printed by C.P. Harrison in 1808. Scale [ca. 1:506,880]. This layer is image 1 of 3 total images of the three sheet source map, representing the western portion of the map.The image inside the map neatline is georeferenced to the surface of the earth and fit to the North Carolina State Plane NAD 1983 coordinate system (in Feet) (Fipszone 3200). All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as roads, drainage, canals, cities and towns, selected public buildings (churches, inns), industry locations (e.g. mills, mines, etc.), selected private buildings with names of property owners, state and county boundaries, shoreline features, and more. Relief shown pictorially and by hachures.This layer is part of a selection of digitally scanned and georeferenced historic maps from the Harvard Map Collection. These maps typically portray both natural and manmade features. The selection represents a range of originators, ground condition dates, scales, and map purposes.
