Suicidal Ideation and Attempts Among Sexual Minority Youth Receiving Social Services

The increased risk for suicidal ideation and attempts among sexual minority youth has been documented in studies using both convenience samples and representative community samples. However, as most youth do not access social services, these studies do not necessarily represent the sexual minority youth that community-based social workers may encounter in their day-today practice. As such, the present study on risk and protective factors related to suicidality surveyed 182 sexual minority youth (ages 14-21) who sought assistance at a community-based social service agency in Denver, CO. Similar to existing literature, the findings suggest that risk factors related to suicidality include hopelessness, methamphetamine use, homelessness, and inschool victimization. However, unlike studies of the general youth population, this study found that African American and male sexual minority youth were not at lower risk of suicidality than sexual minority youth who were, respectively, white or female. Additionally, our findings suggest that the presence of gay-straight alliances in schools may function as a protective resource for sexual minority youth. Implications for social work practice are discussed

Active router approach to defeating denial-of-service attacks in networks

Denial-of-service attacks represent a major threat to modern organisations who are increasingly dependent on the integrity of their computer networks. A new approach to combating such threats introduces active routers into the network architecture. These active routers offer the combined benefits of intrusion detection, firewall functionality and data encryption and work collaboratively to provide a distributed defence mechanism. The paper provides a detailed description of the design and operation of the algorithms used by the active routers and demonstrates how this approach is able to defeat a SYN and SMURF attack. Other approaches to network design, such as the introduction of a firewall and intrusion detection systems, can be used to protect networks, however, weaknesses remain. It is proposed that the adoption of an active router approach to protecting networks overcomes many of these weaknesses and therefore offers enhanced protection

Different forms of the bovine PrP gene have five or six copies of a short, G-C-rich element within the protein-coding exon

Current models of the virus-like agents of scrapie and bovine spongiform encephalopathy (BSE) have to take into account that structural changes in a host-encoded protein (PrP protein) exhibit an effect on the time course of these diseases and the survival time of any man or animal exposed to these pathogens. We report here the sequence of different forms of the bovine PrP gene which contain either five or six copies of a short, G-C-rich element which encodes the octapeptide Pro-His-Gly-Gly-Gly-Trp-Gly-Gln or its longer variants Pro-Gln/His-Gly-Gly-Gly-Gly-Trp-Gly-Gln. Out of 12 cattle, we found eight animals homozygous for genes with six copies of the Gly-rich peptide (6:6), while four were heterozygous (6:5). Two confirmed cases of BSE occurred in (6: 6) homozygous animals. Bovine spongiform encephalopathy (BSE) is a transmissible disease (Fraser et al., 1988; Dawson et al., 1990; Barlow & Middleton, 1990) which produces neuropathological lesions in cattle similar to those seen in ovine scrapie (Wells et al., 1987) and the rare human dementias Creutzfeldt-Jakob disease (CJD) and Gerstmann-Str/iussler syndrome (GSS) (Beck & Daniel, 1987). A cellular membrane protein (PrP) has a key role in the transmission and development of these diseases. This protein accumulates in the brain and other tissues during the protracted time course of these diseases and, in a disease-specific, protease-resistant isoform (SAF-PrP), has been purified by subcellular fractionation of scrapie

An Efficient Euler Method to Predict Shock Migration on a Straked Delta Wing Design

In support of the Air Force Office of Scientific Research, this project sought to identify the significance of nonlinear aerodynamic phenomena in regards to LCO of a straked delta wing design. Previous works include unsteady Navier-Stokes aeroelastic analysis of various wing designs and flight test of F-16 transonic LCO with interest focused on oscillatory SITES behavior. The research presented within this investigation further expanded the understanding of unsteady aerodynamics by performing aeroelastic analysis of a wing oscillated in pitch with an Euler-based, boundary layer coupled numerical method (ZEUS). The wing was tested for a multitude of LCO parameters such as median AoA, oscillation amplitude, oscillation frequency, Mach number, and the type of numerical solver used. Computed pressure data sets were analyzed along the wing\u27s surface at 4 chordwise stations along the wing\u27s span. Results indicate that oscillatory shock migration occurs in response to the pitching motion of the wing. ZEUS has the capability to run either a fully inviscid solution or a boundary layer coupled solution (BLC). While the use of both methods found shock migration to occur, the BLC solution predicted more significant shock migration. The inviscid solution predicted more aggressive shocks located further aft on the wing than the BLC solution. In regards to oscillation amplitude, increasing the amplitude resulted in a greater range of shock migration than lower amplitude cases. Both oscillation frequencies tested did not show any noteworthy differences. The aforementioned findings support the theory that potential oscillatory shock migration can occur during certain cases of transonic LCO. In addition, it was concluded that based on the flow solver used (ZEUS), shock movement during LCO is not purely a function of viscosity (SITES), although the modeling of viscous effects does affect the range of shock migration

Names and what they reveal about a character in Raymond Carver\u27s What We Talk About When We Talk About Love

Focusing strictly on Raymond Carver’s short-story cycle What We Talk About When We Talk About Love (1981), this presentation aims to reveal what the motif of names reveal about a character’s attempts or lack of attempts to connect and communicate. Carver often shows this through point-of-view or dialogue, revealing who characters are and how they perceive the world around them. The smaller glimpses of names, whether it be through dialogue or perspective, in this short-story cycle illuminate how characters either attempt to connect and communicate or do not try at all, often unable to give a reason or explanation as to why. Names through perspective and dialogue can suggest connection and attempts at communication, while a lack of naming can suggest a lack of an attempt at connection and communication. Knowing how Carver manipulates his stories using names, one finds how characters view themselves and the world around them and how these characters are unable to name what fell apart or is falling apart in their lives, if they even realize that something is falling apart at all. Through the motif of names, the character’s true identity and what they think not only of themselves but also of others is revealed. The motif of names runs all throughout the cycle and is especially prominent in “Why Don’t You Dance?,” “Gazebo,” “Mr. Fixit and Mr. Coffee,” The Bath,” “Tell the Women We’re Going,” Popular Mechanics” and “Everything Stuck to Him.

Stability of continuously pumped atom lasers

A multimode model of a continuously pumped atom laser is shown to be unstable below a critical value of the scattering length. Above the critical scattering length, the atom laser reaches a steady state, the stability of which increases with pumping. Below this limit the laser does not reach a steady state. This instability results from the competition between gain and loss for the excited states of the lasing mode. It will determine a fundamental limit for the linewidth of an atom laser beam.Comment: 4 page

Multimode quantum limits to the linewidth of an atom laser

The linewidth of an atom laser can be limited by excitation of higher energy modes in the source Bose-Einstein condensate, energy shifts in that condensate due to the atomic interactions, or phase diffusion of the lasing mode due to those interactions. The first two are effects that can be described with a semiclassical model, and have been studied in detail for both pumped and unpumped atom lasers. The third is a purely quantum statistical effect, and has been studied only in zero dimensional models. We examine an unpumped atom laser in one dimension using a quantum field theory using stochastic methods based on the truncated Wigner approach. This allows spatial and statistical effects to be examined simultaneously, and the linewidth limit for unpumped atom lasers is quantified in various limits.Comment: 8 Figure
