Negative intrusive thoughts and dissociation as risk factors for self-harm.

Relationships between self-harm and vulnerability factors were studied in a general population of 432 participants, of whom 30% reported some experience of self-harm. This group scored higher on dissociation and childhood trauma, had lower self-worth, and reported more negative intrusive thoughts. Among the non-harming group, 10% scored similarly to the self-harmers on the dissociation and self-worth scales, and engaged in potentially maladaptive behaviors that are not defined as indicating clinical self-harm, but experienced fewer negative intrusive thoughts. This group may be at risk of future self-harm if they begin to experience negative intrusive thoughts. If negative intrusive thoughts are playing a causal role, then therapeutic approaches tackling them may help those who are currently self-harming

Electroluminescent mis structures incorporating langmuir-blodgett films

The Langmuir-Blodgett {LB) technique provides an excellent method of depositing thin, uniform, insulating films of accurately defined thickness. They can therefore be used effectively in the investigation of metal/thin insulator/ semiconductor electroluminescent structures where the insulator requirements are good dielectric properties allied to uniformity and an accurately defined thickness. The insertion of a fatty acid LB film into the gold/n-type GaP system produces an increase in the effective barrier height of the device and also enables electroluminescence to be observed. The electroluminescent efficiency is shown to depend on the thickness of the organic film whereas the increase in the effective barrier height is relatively independent of this parameter. The optimum efficiency is obtained for a film thickness of approximately 27 mm, well above that predicted on the basis of direct quantum mechanical tunnelling, The increase in the effective barrier height is shown not to be due to an increased band bending in the semiconductor and a simple energy band model, which accounts for most of the experimental observations, is proposed. Measurements made on the diodes under illumination both support the proposed model and provide information about the mechanism of minority carrier injection. Diodes fabricated using phthalocyanine as the LB film exhibit very different characteristics, in particular the optimum thickness for EL efficiency is approximately 5.6 mm and the diodes appear to conform to the conventional tunnel injection theory. The prospects for commercial exploitation are quite promising in the case of the phthalocyanine-based diodes, particularly if the system can be extended to incorporate an efficient II-VI phosphor as the luminescent material. The results of preliminary experiments using ZnSe as the semiconductor are encouraging in this respect. Preliminary results for two other potential applications of LB films in metal/insulator/semiconductor devices are also described. The first of these concerns an attempt to invert the surface of p-type GaAs, with a view to producing an n-channel inversion mode field effect transistor, and the second describes the high field injection of charge into silicon dioxide, which has potential applications in the field of semiconductor memory devices

A Study to Develop a Curriculum for the Three Year Old Based on the Competencies for Three Year Olds Listed by the Florida Kindergarten Council, Inc.

This curriculum project reviews the methods, materials, movements, music and reading activities that have been shown in the literature to be appropriate for teaching social, emotional, intellectual, and physical skills to three year olds. The development, major findings, various methods, and teacher effectiveness in early childhood education are also discussed. This curriculum project is specifically designed for three year old skills and abilities as listed by The Florida Kindergarten Council, Inc., 1987. The criteria for selection of the activities is included. This project includes a list of the reviewed activities arranged in the format of a nine month calendar and categorized under one of the following headings; art activities, movement activities, music and recipes. One color, number and shape will be introduced into the curriculum each month. Finally, suggested stories appropriate for the central theme of each month will be included for teachers to use in reinforcing the concepts presented

Dark state adiabatic passage with branched networks and high-spin systems: Spin separation and entanglement

Adiabatic methods are potentially important for quantum information protocols because of their robustness against many sources of technical and fundamental noise. They are particularly useful for quantum transport, and in some cases elementary quantum gates. Here, we explore the extension of a particular protocol, dark state adiabatic passage, where a spin state is transported across a branched network of initialized spins, comprising one "input" spin, and multiple leaf spins. We find that maximal entanglement is generated in systems of spin-half particles, or where the system is limited to one excitation

Fifteen minute consultation: stabilisaton of the high risk newborn infant beside the mother

Paediatric and adult resuscitation is often performed with family present. Current guidelines recommend deferred umbilical cord clamping as part of immediate neonatal care, requiring neonatal assessment next to the mother. This paper describes strategies for providing care beside the mother using both standard resuscitation equipment and a trolley designed for this purpose

Oilheat research agenda: A ten year blueprint for residential oilheat research and development in the Twenty-First Century

This report summarizes a joint research agenda planned for the US Department of Energy and the National Oilheat Research Alliance (NORA) under a cooperative effort between the Federal government and the private sector industries involved in oilheat marketing. The objective of the oilheat research program is to develop the technical basis for improved equipment designs and operating strategies based on an enhanced understanding of oil-burning fundamentals, heat transfer, and associated environmental factors. The program will continue to provide the oil-fueled heating equipment industry with the basis for developing a new, modern generation of equipment and provide the oil marketers, equipment installers, and consumers with improved knowledge of how best to install, maintain, and operate such equipment for maximum performance and minimum fuel use and environmental impact
