Structural indicators for inclusive systems in and around schools. Analytical Report

International evidence indicates that school systems need to change in order to tackle early school leaving and improve social inclusion in education and society. Policy-makers and school actors require practical tools to assist them in this process, made all the more urgent by the EU2020 headline target to reduce early school leaving. This report develops such practical tools; it is designed to inform strategic policy and practice by offering an innovative framework of structural indicators for early school leaving prevention and inclusion in school. It draws upon key European Council and Commission policy documents on early school leaving prevention, and also on the Paris Declaration 2015 on promoting common values of freedom, tolerance and non-discrimination through education, which includes a focus on social marginalization

Oral Health Knowledge and Attitudes of Elementary Schoolteachers in Michigan

Teachers at elementary schools in two areas (urban and rural) of Michigan were surveyed to determine their sources of information about oral health and their knowledge and attitudes about dental diseases and disease prevention. Questionnaires were completed by 404 teachers (62% response rate). More than 80 percent of respondents from both areas were female. Demographic characteristics that were significantly different between groups included: median ages of urban and rural respondents (P<.01), median numbers of years in teaching (P<.01), and median years in residence (P<.03). Despite these differences, responses to the questionnaire varied little. For both groups, the most frequently cited sources of information about dental health were dentist's office (82%), followed by magazines and books (74%). The teachers considered preventing tooth decay as the most important reason for good oral hygiene. When asked to rank the effectiveness of ten methods of preventing caries in children, teachers ranked efficacious methods such as fluoridated water and pit and fissure sealants lower than making regular dental visits and reducing intake of sugared foods. Asked to rank the most effective method for children to receive fluoride, urban respondents ranked fluoridated water first, while rural respondents ranked this measure third. Findings suggest that teachers' knowledge about oral health and current methods of prevention is incomplete, is inaccurate in some instances, and varies little by geographic area.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66134/1/j.1752-7325.1989.tb02020.x.pd

Traceable measurements of the activity concentration in air

The nuclear reactions induced by high energetic protons in heavy targets such as UC/sub 2/ and ThC cause a particular, complex radiation protection task at facilities like ISOLDE: the measurement of a mixture of different isotopes of the radioactive noble gas radon and the radon progenies in air. The knowledge of their respective activity concentration is fundamental for exposure assessments. Due to the complex mixture of activity concentrations in air, its precise determination is quite difficult. Therefore, a new procedure for taking reference samples was developed and implemented for the traceable measurement of the activity concentration of radioactive ions (e.g., radon progenies) in air. This technique is combined by measuring alpha -particles with a multi-wire ionization chamber for the parallel on-line determination of the activity concentration of different radon isotopes.

Die Klassenzugehörigkeit von Ehepaaren 1970 und 1993: Kontinuität oder Wandel?

'Die letzten Dekaden werden oft beschrieben als eine Phase der Auflösung traditioneller klassenspezifischer Strukturen und einer Zunahme individualisierter Lebensbeziehungen. Dies müsste sich auch als Abschwächung klassenspezifischer Heiratsbeziehungen bemerkbar machen. Für die Zeitpunkte 1970 und 1993 wurde diese Hypothese mit Daten der Volkszählung und des Mikrozensus überprüft. Es konnte eine weitgehende Stabilität in den Mustern der Klassenzugehörigkeit von verheirateten Männern und Frauen festgestellt werden. Zurückgeführt wird dies auf einen vor allem über soziale, kulturelle und regionale Faktoren stark selektierten und strukturierten Heiratsmarkt, der - entlang dieser Faktoren - in relativ homogene Subheiratsmärkte zerfällt, innerhalb derer die Partnerwahlen überwiegend stattfinden.'

Calculation of the substitutional fraction of ion-implanted He in an Fe target

Ion-implantation is a useful technique to study irradiation damage in nuclear materials. To study He effects in nuclear fusion conditions, He is co-implanted with damage ions to reproduce the correct He/dpa ratios in the desired or available depth range. However, the short-term fate of these He ions, i.e over the time scales of their own collisional phase, has not been yet unequivocally established. Here we present an atomistic study of the short-term evolution of He implantation in an Fe substrate to approximate the conditions encountered in dual ion-implantation studies in ferritic materials. Specifically, we calculate the fraction of He atoms that end up in substitutional sites shortly after implantation, i.e. before they contribute to long-term miscrostructural evolution. We find that fractions of at most 3% should be expected for most implantation studies. In addition, we carry out an exhaustive calculation of interstitial He migration energy barriers in the vicinity of matrix vacancies and find that they vary from approximately 20 to 60 meV depending on the separation and orientation of the He-vacancy pair.Comment: 7 pages, 6 figures, 2 table

Molecular detection of novel herpesviruses and adenoviruses in two species of Australian freshwater turtles

Cutaneous lesions were observed in a wild population of freshwater turtles during routine disease surveillance at Alligator Creek, Townsville, Australia. Previous attempts to identify the causative agent of these lesions were unsuccessful; however, existing evidence suggests viral etiology. To further investigate these events, blood samples and lesion, oral and cloacal swabs collected from 128 freshwater turtles at two locations (Alligator Creek and Ross River) were screened for herpesvirus, adenovirus, poxvirus and papillomavirus by polymerase chain reaction. We detected three novel herpesviruses (chelid herpesvirus 1–3) as well as three adenoviruses (saw-shelled turtle adenovirus 1–3). Phylogenetic analyses showed that the herpesviruses formed a distinct clade with the tumour-associated chelonid alphaherpesvirus 5 (Scutavirus chelonidalpha5) within the subfamily Alphaherpesvirinae. The adenoviruses clustered with members of the genus Testadenovirus. Although the novel herpesviruses and adenoviruses could not be linked to the occurrence of cutaneous lesions, further characterisation will help provide better insights into their clinical, epidemiological and conservation significance

History of Body Contouring

The evolution of body contouring follows decades of procedures and technologic advances in body shaping. Beginning many decades ago with extensive surgical resections of skin and subcutaneous fat, the evolution was dramatically changed with the introduction of suction assisted lipectomy (liposuction). Further refinement in the technique of liposuction allowed more precise sculpting of the body and, most recently, has evolved to high definition liposuction. Following the introduction of liposuction in the early 1980s, energy based devices were developed to allow non or minimally invasive procedures to sculpt the body. The energy sources include laser energy, radiofrequency energy, ultrasonic energy, and plasma based energy. This evolution has provide the cosmetic surgeon with a variety of options to obtain optimal body contouring in a variety of clinical presentations. The safety and the efficacy of these procedures are the most important considerations in adopting new technology and techniques

An attempt to explain the neurological symptoms of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

There is accumulating evidence of endothelial dysfunction, muscle and cerebral hypoperfusion in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). In this paper we deduce the pathomechanisms resulting in central nervous pathology and the myriad of neurocognitive symptoms. We outline tentative mechanisms of impaired cerebral blood flow, increase in intracranial pressure and central adrenergic hyperactivity and how they can well explain the key symptoms of cognitive impairment, brain fog, headache, hypersensitivity, sleep disturbances and dysautonomia

Fermi-surface collapse and dynamical scaling near a quantum critical point

Quantum criticality arises when a macroscopic phase of matter undergoes a continuous transformation at zero temperature. While the collective fluctuations at quantum-critical points are being increasingly recognized as playing an important role in a wide range of quantum materials, the nature of the underlying quantum-critical excitations remains poorly understood. Here we report in-depth measurements of the Hall effect in the heavy-fermion metal YbRh2Si2, a prototypical system for quantum criticality. We isolate a rapid crossover of the isothermal Hall coefficient clearly connected to the quantum-critical point from a smooth background contribution; the latter exists away from the quantum-critical point and is detectable through our studies only over a wide range of magnetic field. Importantly, the width of the critical crossover is proportional to temperature, which violates the predictions of conventional theory and is instead consistent with an energy over temperature, E/T, scaling of the quantum-critical single-electron fluctuation spectrum. Our results provide evidence that the quantum-dynamical scaling and a critical Kondo breakdown simultaneously operate in the same material. Correspondingly, we infer that macroscopic scale-invariant fluctuations emerge from the microscopic many-body excitations associated with a collapsing Fermi-surface. This insight is expected to be relevant to the unconventional finite-temperature behavior in a broad range of strongly correlated quantum systems.Comment: 5 pages, plus supporting materia
