Diffusion technique for lithium-doped silicon

Sample is doped by constructing a sandwich of five slices of silicon with lithium dopant deposited on the outside surfaces of the second and fourth slices and placing the sample in the middle. Upon heating, the lithium diffuses through the carrier slices and into the sample wafer

Fluorescence antibunching microscopy

Breaking the diffraction limit in microscopy by utilizing quantum properties of light has been the goal of intense research in the recent years. We propose a quantum superresolution technique based on non-classical emission statistics of fluorescent markers, routinely used as contrast labels for bio-imaging. The technique can be readily implemented using standard fluorescence microscopy equipment

Passthrough of Exchange Rates and Purchasing Power Parity

In this paper we develop and test two hypotheses about purchasing power parity (PPP) derived from the pricing behavior of profit- maximizing, exporting firms. The first is that changes in the price of traded goods relative to domestic substitutes, due to partial pass- through of exchange rates, will affect the PPP relation. The second is that PPP should hold on forward rather than spot exchange rates, due to hedging by firms. Using quarterly data for the United States, Canada, France, Germany, Japan and the United Kingdom, we find considerable support for the first but not the second hypothesis.

The identification and psychological treatment of panic disorder in adolescents: a survey of CAMHS clinicians

Background Panic disorder is experienced by around 1% of adolescents, and has a significant impact on social and academic functioning. Preliminary evidence supports the effectiveness of panic disorder specific treatment in adolescents with panic disorder, however panic disorder may be overlooked in adolescents due to overlapping symptoms with other anxiety disorders and other difficulties being more noticeable to others. The aim of this study was to establish what training National Health Service (NHS) Child and Adolescent Mental Health Services (CAMHS) clinicians have received in psychological therapies and panic disorder and how they identify and treat panic disorder in adolescents. Method CAMHS clinicians from a range of professions (n = 427), who were delivering psychological treatments to children and adolescents with anxiety disorders, participated. They completed a cross-sectional, online survey, including a vignette describing an adolescent with panic disorder, and were asked to identify the main diagnosis or presenting problem. Results Less than half the clinicians (48.6%) identified panic disorder or panic symptoms as the main presenting problem from the vignette. The majority of clinicians suggested CBT would be their treatment approach. However, few identified an evidence-based treatment protocol for working with young people with panic disorder. Almost half the sample had received no training in cognitive behaviour therapy (CBT) and around a fifth had received no training in delivering psychological treatments. Conclusions Only half of CAMHS clinicians identified panic disorder from a vignette and although CBT treatments are widely offered, only a minority of adolescents with panic disorder are receiving treatments developed for, and evaluated with young people with panic disorder. There is a vital need for clinician training, the use of tools that aid identification and the implementation of evidence-based treatments within CAMHS

Speeches Before the Tribal Chiefs of the Iroquois Nation

The following scripts were written by Dr. Robert Kendall impersonating SA-GO-YE WAT-HA (aka, Red Jacket) and Missionary Brother Cram speaking before the tribal chiefs of the Iroquois Nation in Western New York in 1805. Impersonation speaking was developed by Dr. Robert Kendall who taught in the Communication Studies Department at St. Cloud State University between 1971 and 1992. Dr. Kendall described impersonation speaking in this way: Each student chooses an historical character, does independent research on that person, write a speech, locating it in a particular year of that person\u27s adult life, making it interesting and relevant to a [contemporary] audience, assumes that character through costume, attitude, worldview, and mannerisms, and delivers the speech to an open-invitation public
