Depression in children and adolescents: The role of school professionals
Depression in children and adolescents is a significant issue for schools. Research has indicated that most students who see mental health professionals do so within the school setting, indicating a need for effective school-based programs to address mental health issues in the schools. The symptoms of depression and short and long term effects are reviewed. The need for, and necessary components of, a comprehensive mental health system in the school setting is discussed
Carcasses at Fixed Locations Host a Higher Diversity of Necrophilous Beetles
In contrast to other necro mass, such as leaves, deadwood, or dung, the drivers of insect biodiversity on carcasses are still incompletely understood. For vertebrate scavengers, a richer community was shown for randomly placed carcasses, due to lower competition. Here we tested if scavenging beetles similarly show a higher diversity at randomly placed carcasses compared to easily manageable fixed places. We sampled 12,879 individuals and 92 species of scavenging beetles attracted to 17 randomly and 12 at fixed places exposed and decomposing carcasses of red deer, roe deer, and red foxes compared to control sites in a low range mountain forest. We used rarefaction-extrapolation curves along the Hill-series to weight diversity from rare to dominant species and indicator species analysis to identify differences between placement types, the decay stage, and carrion species. Beetle diversity decreased from fixed to random locations, becoming increasingly pronounced with weighting of dominant species. In addition, we found only two indicator species for exposure location type, both representative of fixed placement locations and both red listed species, namely Omosita depressa and Necrobia violacea. Furthermore, we identified three indicator species of Staphylinidae (Philonthus marginatus and Oxytelus laqueatus) and Scarabaeidae (Melinopterus prodromus) for larger carrion and one geotrupid species Anoplotrupes stercorosus for advanced decomposition stages. Our study shows that necrophilous insect diversity patterns on carcasses over decomposition follow different mechanisms than those of vertebrate scavengers with permanently established carrion islands as important habitats for a diverse and threatened insect fauna.publishedVersio

Eu-Doped BaTiO3 Powder and Film from Sol-Gel Process with Polyvinylpyrrolidone Additive
Transparent BaTiO3:Eu3+ films were prepared via a sol-gel method and dip-coating technique, using barium acetate, titanium butoxide, and polyvinylpyrrolidone (PVP) as modifier viscosity. BaTiO3:Eu3+ films ~500 nm thick, crystallized after thermal treatment at 700 ºC. The powders revealed spherical and rod shape morphology. The optical quality of films showed a predominant band at 615 nm under 250 nm excitation. A preliminary luminescent test provided the properties of the Eu3+ doped BaTiO3
Utilizing Rock Art to Trace Human Migration: Case Studies from Sarawak, Malaysian Borneo
Ph.D. University of Hawaii at Manoa 2016.Includes bibliographical references.This study uses rock art as a proxy to track human movement on Borneo during the poorly understood “Neolithic” peopling of Island Southeast Asia, c. 6 - 2 ka. This pivotal time period involved major population movements and the advent of agriculture; it also brought with it new “Neolithic” material culture throughout the region. Rock art is a neglected archaeological data source in Southeast Asian archaeology, and Borneo’s rock art holds great potential for studying modern human movement and symbolic behavior. This dissertation inventories the breadth and depth of Bornean rock art and generates a techno-chronological timeline for Bornean rock art to establish a basis for delineating endemic and intrusive rock art design systems from the Paleolithic through modern periods. It evaluates the Bornean presence of two diagnostically “Neolithic” rock art traditions found elsewhere in Island Southeast Asia and the Pacific: the Austronesian Painting Tradition (APT) and Austronesian Engraving Style (AES). Multiple synchronic and diachronic rock art practices are described, including a distinctly Bornean version of the APT and a single instance of the AES that expand our understanding of the Bornean and Southeast Asian archaeological narratives. This work additionally underscores the continued utility of stylistic analysis, relative dating and long-term, innovative rock art conservation in archaeological research
Inhomogeneities in Alkali-Resistant Hemoglobin. Demonstration of Zone Electrophoretic Differences Using a Cationic Detergent Electrolyte
Abstract
Trimethyloctadecyl ammonium chloride, a cationic active detergent electrolyte, when added to starch gels before electrophoresis, caused selected alteration in the migration rates of alkali-resistant hemoglobin. Other red blood cell pigments were not similarly affected. Electrophoretic inhomogeneity of cord blood and thalassemia hemoglobin was noted. New components of cord blood hemoglobin were revealed by the method. A new component in the hemoglobin of cases of severe thalassemia was demonstrated.</jats:p
