Emerging Areas of Practice for Mental Health Social Workers: Education and Employment

Abstract In recent times in Australia there has been a slow but steady trend among mental health services to employ generic mental health workers from a variety of professional backgrounds. These workers undertake the jobs that were traditionally assigned to social workers. Although many social workers compete successfully for these positions, a question that needs to be explored in the contemporary service and policy context is social work's distinct contribution to the field of mental health. The present paper argues that social work's distinct contribution may lie in the area of psychiatric recovery, especially those areas that link mental health with broader social issues, such as employment and education. The present paper will discuss the role of social work in two areas of recovery, namely supported employment and education. These are emerging areas of practice and social workers must take advantage of these opportunities.
Visualizing the stock market

We describe a new 2-dimensional visualization algorithm capable of presenting detailed information on hundreds of items while emphasizing overall patterns in the data. This display method, which builds on Shneiderman's treemap technique, makes use of both hierarchy and similarity information. We have implemented this display in the SmartMoney Map of the Market, a web page that reports current data on over 500 publicly traded companies.
REVISITING TUNGUSIC CLASSIFICATION FROM THE BOTTOM UP: A COMPARISON OF EVENKI AND OROQEN

uses a tree model, is even less successful in indicating the relationships among languages at a finer level of detail. This article demonstrates that two Tungusic languages, Evenki and Oroqen, which have long been treated as a single language for classification purposes, are better treated as distinct linguistic varieties. The article raises fundamental questions about the current classification of Tungusic languages and suggests a renewed examination of the role of dialect continua and contact languages in understanding the composition of the family. Finally, we question whether a tree-based model is appropriate for classifying languages that have had a high degree of contact and are found in families or branches of a shallow time depth. *
Modelling the Factors Driving the Quality of Meetings in the Software Development Process

It is a well-known fact that communication mechanisms within large-scale software development are important to ensure the success of projects. The empirical study described here investigates factors driving the outcome quality of various types of meetings, taking place during software development activities at Bosch Telecom Private Networks. The dependent variable under study is the perceived quality of the results of a meeting; the independent variables investigated are the number of participants, the setting of a meeting (reason, leadership style), the number of organisational roles involved, and its duration. The analysis methods used to explore and confirm the relationships between independent and dependent variables include Classification Trees and Logistic Regression. In addition, a questionnaire was designed and administered to help us interpret the outcome of the statistical analysis. This study is based on a data set of about two hundred data points (i.e., meetings) and, therefore, made multivariate analysis possible. The results of the study show that there is supporting evidence that several attributes are significant factors driving the quality of meetings. The questionnaire results helped us gain a better understanding of how various factors influence a meeting’s outcome. This, in turn, leads to suggestions on the way to improve communication through meetings. The methodology presented here for data collection and analysis is widely reusable in other software development organisations, and for other process improvement issues to be addressed by measurement.
J-Express: exploring gene expression data using Java

J-Express is a Java application that allows the user to analyze gene expression (microarray) data in a flexible way giving access to multidimensional scaling, clustering, and visualization methods in an integrated manner. Specifically, J-Express includes implementations of hierarchical clustering, k-means, principal component analysis, and self-organizing maps. At present, it does not include methods for comparing two or more experiments for differentially expressed genes. The application is completely portable and requires only that a Java runtime environment 1.2 is installed on the system. Its efficiency allows interactive clustering of thousands of expression profiles on standard personal computers.
Insights into Cyclostome Phylogenomics: Pre-2R or Post-2R

Abstract Interest in understanding the transition from prevertebrates to vertebrates at the molecular level has resulted in accumulating genomic and transcriptomic sequence data for the earliest groups of extant vertebrates, namely, hagfishes (Myxiniformes) and lampreys (Petromyzontiformes). Molecular phylogenetic studies on species phylogeny have revealed the monophyly of cyclostomes and the deep divergence between hagfishes and lampreys (more than 400 million years). In parallel, recent molecular phylogenetic studies have shed light on the complex evolution of the cyclostome genome. This consists of whole genome duplications, shared at least partly with gnathostomes (jawed vertebrates), and cyclostome lineage-specific secondary modifications of the genome, such as gene gains and losses. Therefore, the analysis of cyclostome genomes requires caution in distinguishing between orthology and paralogy in gene molecular phylogeny at the gene family scale, as well as between apomorphic and plesiomorphic genomic traits in larger-scale analyses. In this review, we propose possible ways of improving the resolvability of these evolutionary events, and discuss probable scenarios for cyclostome genome evolution, with special emphasis on the hypothesis that two-round (2R) genome duplication events occurred before the divergence between cyclostomes and gnathostomes, and therefore that a post-2R state is a genomic synapomorphy for all extant vertebrates.
A Distributed Throughput-Optimal CSMA / CA

This paper addresses a distributed throughputoptimal CSMA/CA for wireless ad hoc networks, which is called the preemptive CSMA/CA. It achieves the optimality in a completely distributed fashion, even with discrete backoff time, non-zero carrier sense delay and data packet collisions. The algorithm is derived from the extension of Q-CSMA by Ni, Bo and Srikant to include collisions and is similar to the Jiang and Walrand’s CSMA/CA. The analysis on the preemptive CSMA/CA provides with the understanding on the relationship among the throughput-optimal CSMA/CAs in the literature.
Race in the Schools: Perpetuating White Dominance

recent years. White Men on Race emphasizes the crucial role these elite white men play in perpetuating systemic racism, despite their personal convictions. The anecdotes and extensive quotations drawn from the interviews make compelling reading. The common “color-blind” framework embraced by many of these elite white men has serious policy implications. Because many of these subjects do not see inequality as racially based, they do not see racial remedies as necessary. Mirroring the results of other research on white populations, they largely believe serious racial inequality to be a thing of the past, and see antidiscrimination efforts as unnecessary. In their workplaces, then, people of color who raise issues of discrimination are cast as troublemakers, introducing the “race card. ” In this elite world, conformity to traditional, racial stereotypes is continually reinforced and rewarded, and given the lack of equal status interactions and the extent of media bias, there is little likelihood that white Americans will have much empathy for people of color, nor embrace African Americans as full fellow Americans, with similar values and priorities. My only disappointment with this text was that the analysis was limited to race. While the authors focus specifically on elite white men, there is little discussion of gender and the ways in which these men’s privileged status and attitudes are a result of cultural constructions of race and gender, and their own experiences not only as whites, but as men. The extent to which these men have been successful in their careers and able to wield the power they possess is a function of their privileged gender status as well. Exploring the intersections of race, class, and gender in these men’s experiences and attitudes toward race would have considerably strengthened an already strong text. White Men on Race makes a fine contribution to our understanding of racial privilege and the ways in which privilege is perpetuated over generations. Students will find the text easy to read, and it is appropriate for undergraduate and graduate courses dealing with race and privilege. Race in the Schools: Perpetuating White Dominance? by Judith R.

Human immunodeficiency virus type 1 LTR TATA and TAR region sequences required for transcriptional regulation.

The human immunodeficiency virus (HIV) type 1 LTR is regulated at the transcriptional level by both cellular and viral proteins. Using HeLa cell extracts, multiple regions of the HIV LTR were found to serve as binding sites for cellular proteins. An untranslated region binding protein UBP‐1 has been purified and fractions containing this protein bind to both the TAR and TATA regions. To investigate the role of cellular proteins binding to both the TATA and TAR regions and their potential interaction with other HIV DNA binding proteins, oligonucleotide‐directed mutagenesis of both these regions was performed followed by DNase I footprinting and transient expression assays. In the TATA region, two direct repeats TC/AAGC/AT/AGCTGC surround the TATA sequence. Mutagenesis of both of these direct repeats or of the TATA sequence interrupted binding over the TATA region on the coding strand, but only a mutation of the TATA sequence affected in vivo assays for tat‐activation. In addition to TAR serving as the site of binding of cellular proteins, RNA transcribed from TAR is capable of forming a stable stem‐loop structure. To determine the relative importance of DNA binding proteins as compared to secondary structure, oligonucleotide‐directed mutations in the TAR region were studied. Local mutations that disrupted either the stem or loop structure were defective in gene expression. However, compensatory mutations which restored base pairing in the stem resulted in complete tat‐activation. This indicated a significant role for the stem‐loop structure in HIV gene expression. To determine the role of TAR binding proteins, mutations were constructed which extensively changed the primary structure of the TAR region, yet left stem base pairing, stem energy and the loop sequence intact. These mutations resulted in decreased protein binding to TAR DNA and defects in tat‐activation, and revealed factor binding specifically to the loop DNA sequence. Further mutagenesis which inverted this stem and loop mutation relative to the HIV LTR mRNA start site resulted in even larger decreases in tat‐activation. This suggests that multiple determinants, including protein binding, the loop sequence, and RNA or DNA secondary structure, are important in tat‐activation and suggests that tat may interact with cellular proteins binding to DNA to increase HIV gene expression.
Human combinatorial libraries yield rare antibodies that broadly neutralize hepatitis C virus

One way to dissect the antibody response to an invading microorganism is to clone the antibody repertoire from immune donors and subsequently characterize the specific antibodies. Recently, methodological advances have allowed investigations of neutralizing antibodies against hepatitis C virus (HCV) in vitro. We have investigated three human mAbs, previously isolated from an individual infected with HCV of genotype 2b, that are known to cross-react in a binding assay to the envelope E2 protein of genotypes 1a and 1b. We now report that two of them have a neutralizing activity with a breadth not previously observed. Indeed, mAbs 1:7 and A8 recognized E2 from all of the six major genotypes, and they neutralized retroviral pseudoparticles [HCV pseudoparticles (HCVpp)] carrying genetically equally diverse HCV envelope glycoproteins. Importantly, these antibodies were also able to neutralize the cell culture infectious HCV clone JFH-1 in vitro, with IC50 values of 60 ng/ml and 560 ng/ml, respectively. The conformational epitopes of these two broadly reactive antibodies were overlapping yet distinct and involved amino acid residues in the 523–535 region of E2, known to be important for the E2–CD81 interaction. The third antibody clone, representing a dominant population in the initial screen for these antibodies, was less broadly reactive and was unable to neutralize the genotype 2a infectious clone JFH-1. Our results confirm at the clonal level that broadly neutralizing human anti-HCV antibodies can be elicited and that the region amino acids 523–535 of the HCV envelope glycoprotein E2 carries neutralizing epitopes conserved across all genotypes.
Connection Stability Analyze Based on Dynamic Clustering Algorithm for Mobile Ad hoc Network

With the increase in size and application are of the communication network, more attention has been paid to the invulnerability of mobile ad hoc network. Based on studying deeply in the characteristic of mobile ad hoc network, analyzing the shortages in invulnerability algorithm previously, this paper presents a mathematically tractable model of node motion to derive a precise relation between mobility and connection stability. We improve the first order energy consumption model with dynamic clustering firstly and then build a incidence matrix to depict the connectivity of the network nodes in a dynamic network model. Finally, we simulate the network invulnerability related to time. As a result, it validates the high invulnerability of the dynamic clustering ad hoc networks.
An efficient methodology for parallel concatenation of LDPC codes with reduced complexity and decoding delay

Parallel concatenated Gallager codes (PCGC) is a class of concatenated codes based on LDPC component codes. Conventional attempts for concatenating LDPC in parallel using the well known ‘Turbo code structure’ without interleavers have not been widely successful, because of its performance limitation and decoding delay. In this paper we present an efficient methodology for parallel concatenation of LDPC codes. We show that proposed methodology for PCGC outperforms existing PCGC in terms of BER performance in both AWGN and flat fading Rayleigh channels. We also present that proposed PCGC outperforms existing PCGC in terms of complexity as well as decoding delay.
Feed gap influence for printed multiple ring fractal antennas

A simple structure of printed multiple ring fractal antennas has already been investigated in our previous work, which demonstrate better performance than conventional antennas as dual-band or triple-band element This paper presents the feed gap influence for printed multiple ring fractal antennas. As the ground plane is under part of the feed line, the feed gap between antenna and ground plane is the key point for impedance matching and obtaining good performance of radiation pattern and S-parameter. After comparing a large number of simulation results, an expression is given to indicate the relationship between feed gap h and the radius of biggest ring R. The single antenna unit has the potential of operating in several of the currently existing systems such as GSM, UMTS, WLAN and Bluetooth
Neurologic Dysfunction and Male Infertility in Drosophila porin Mutants

Voltage-dependent anion channels (VDACs) are a family of small pore-forming proteins of the mitochondrial outer membrane found in all eukaryotes. VDACs play an important role in the regulated flux of metabolites between the cytosolic and mitochondrial compartments, and three distinct mammalian isoforms have been identified. Animal and cell culture experiments suggest that the various isoforms act in disparate roles such as apoptosis, synaptic plasticity, learning, muscle bioenergetics, and reproduction. In Drosophila melanogaster, porin is the ubiquitously expressed VDAC isoform. Through imprecise excision of a P element insertion in the porin locus, a series of hypomorphic alleles have been isolated, and analyses of flies homozygous for these mutant alleles reveal phenotypes remarkably reminiscent of mouse VDAC mutants. These include partial lethality, defects of mitochondrial respiration, abnormal muscle mitochondrial morphology, synaptic dysfunction, and male infertility, which are features often observed in human mitochondrial disorders. Furthermore, the observed synaptic dysfunction at the neuromuscular junction in porin mutants is associated with a paucity of mitochondria in presynaptic termini. The similarity of VDAC mutant phenotypes in the fly and mouse clearly indicate a fundamental conservation of VDAC function. The establishment and validation of a new in vivo model for VDAC function in Drosophila should provide a valuable tool for further genetic dissection of VDAC role(s) in mitochondrial biology and disease, and as a model of mitochondrial disorders potentially amenable to the development of treatment strategies.
Neighbourhood socio-economic position, late presentation and outcomes in people living with HIV in Switzerland

Objectives:Inequalities and inequities in health are an important public health concern. In Switzerland, mortality in the general population varies according to the socio-economic position (SEP) of neighbourhoods. We examined the influence of neighbourhood SEP on presentation and outcomes in HIV-positive individuals in the era of combination antiretroviral therapy (cART). Methods:The neighbourhood SEP of patients followed in the Swiss HIV Cohort Study (SHCS) 2000–2013 was obtained on the basis of 2000 census data on the 50 nearest households (education and occupation of household head, rent, mean number of persons per room). We used Cox and logistic regression models to examine the probability of late presentation, virologic response to cART, loss to follow-up and death across quintiles of neighbourhood SEP. Results:A total of 4489 SHCS participants were included. Presentation with advanced disease [CD4+ cell count <200 cells/&mgr;l or AIDS] and with AIDS was less common in neighbourhoods of higher SEP: the age and sex-adjusted odds ratio (OR) comparing the highest with the lowest quintile of SEP was 0.71 [95% confidence interval (95% CI) 0.58–0.87] and 0.59 (95% CI 0.45–0.77), respectively. An undetectable viral load at 6 months of cART was more common in the highest than in the lowest quintile (OR 1.52; 95% CI 1.14–2.04). Loss to follow-up, mortality and causes of death were not associated with neighbourhood SEP. Conclusion:Late presentation was more common and virologic response to cART less common in HIV-positive individuals living in neighbourhoods of lower SEP, but in contrast to the general population, there was no clear trend for mortality.
Vein Imaging: A New Method of Near Infrared Imaging, Where a Processed Image Is Projected onto the Skin for the Enhancement of Vein Treatment

BACKGROUND A new noninvasive vein imaging device initially developed for phlebotomy has been tested for the first time for vein treatment. This unique device captures a near infrared vein image, processes it, and projects it onto the skin using green light. OBJECTIVE To perform the first clinical tests of the device in phlebology. METHODS AND MATERIALS A pilot study on 23 subjects with varicose veins and telangiectasias was performed. The VeinViewer prototype (V-V-P; Luminetx Corp., Memphis, TN) was tested in five situations: diagnosing feeder veins with the V-V-P, comparison between the V-V-P and ultrasound, marking varicose veins with or without the device, phlebectomy using the V-V-P, and the use of laser and sclerotherapy guided by the V-V-P. RESULTS One hundred percent of subjects had feeder veins identified by the V-V-P. The ultrasound machine detected fewer feeder veins than the V-V-P, and the device identified more veins than the naked eye in all subjects. The V-V-P could help in finding feeder veins during phlebectomy and in guiding laser and sclerotherapy treatments. CONCLUSIONS The device could identify veins that were invisible to the naked eye and too shallow for ultrasound detection. The V-V-P may help find feeder veins and may also help various types of vein treatments.
Adaptive stepsize algorithms for Langevin dynamics

We discuss the design of an invariant measure-preserving transformed dynamics for the numerical treatment of Langevin dynamics based on rescaling of time, with the goal of sampling from an invariant measure. Given an appropriate monitor function which characterizes the numerical difficulty of the problem as a function of the state of the system, this method allows the stepsizes to be reduced only when necessary, facilitating efficient recovery of long-time behavior. We study both the overdamped and underdamped Langevin dynamics. We investigate how an appropriate correction term that ensures preservation of the invariant measure should be incorporated into a numerical splitting scheme. Finally, we demonstrate the use of the technique in several model systems, including a Bayesian sampling problem with a steep prior.

An application of this approach is presented based on a study of a Community of Practice (CoP) ill the information . lystems domain conducted in four research cycles over several years. The major benefits of the evolved method in elude the flexibility of the resulting research process, and the capacity to capture diverse project outcomes, at the same time making themy building more transparent
Comparing Cognitive Profiles of Licensed Drivers with Mild Alzheimer's Disease and Mild Dementia with Lewy Bodies

Purpose. Alzheimer's disease (AD) and dementia with Lewy Bodies (DLB) constitute two of the most common forms of dementia in North America. Driving is a primary means of mobility among older adults and the risk of dementia increases with advanced age. The purpose of this paper is to describe the cognitive profile of licensed drivers with mild AD and mild DLB. Method. Licensed drivers with mild AD, mild DLB, and healthy controls completed neuropsychological tests measuring general cognition, attention, visuospatial/perception, language, and cognitive fluctuations. Results. The results showed differences between healthy controls and demented participants on almost all neuropsychological measures. Participants with early DLB were found to perform significantly worse on some measures of attention and visuospatial functioning in comparison with early AD. Discussion. Future research should examine the relationship between neuropsychological measures and driving outcomes among individuals with mild AD and mild DLB.
