It Started Over Coffee: The Aboriginal Community Youth Resilience Network (ACYRN) in Mi'kmaq And Maliseet Communities of Atlantic Canada.

April Maloney and Dawn Caldwell both live in Halifax, Nova Scotia. Since 2003, they have worked together to develop a project that would examine resilience to suicide among Aboriginal youth. First, with funding from the Ottawa ACADRE (http://www.cihr-irsc.gc.ca/e/27071.html), they worked with two communities to develop a culturally appropriate research questionnaire for youth. Once the questionnaire was finalized, Dawn and April met with other communities in Atlantic Canada, to discuss youth resilience using the questionnaire they had completed and inviting communities to join them in a community based research project. In 2005, the Aboriginal Community Youth Resilience Network (ACYRN) was funded, allowing 10 communities in Atlantic Canada and 8 communities in Alberta to research youth wellness using the questionnaire first developed by Dawn and April. This article covers some of the issues that Dawn and April faced in growing their research idea into a research network.
The etiology of burnout syndrome and the levels of stress among nurses

Introduction : Burnout syndrome refers to emotional exhaustion and diminished personal performance as a result of the individual’s dwindling energy resources and adaptation power due to chronic job stresses. The present study was performed to examine the effect of different etiologies of this syndrome and the stress levels of nurses working in hospitals affiliated with Jahrom University of Medical Sciences. Materials and Methods: This study was a descriptive cross-sectional study. Census sampling was performed on all 212 nurses working in the hospitals of Jahrom University of Medical Sciences (Motahhari and Peymanieh) in winter 2012 and spring 2013. The data collection instrument included two checklists for investigating the causes of burnout syndrome and Cohen’s perceived stress scale. The data were analyzed with the SPSS software, using descriptive statistical methods, regression, and Pearson and Spearman correlation coefficients. Results: According to the nurses, respectively, were the most important Most nurses suffered medium levels of stress. A statistically significant relationship was observed between the burnout degree and stress levels (p<0.05). Conclusion: The results showed that, according to the nurses, different factors had different effects on the incidence of job burnout syndrome; therefore, the incidence rate of this syndrome should be reduced by taking appropriate measures to ease different stresses.
Expanding the Genetic Code of Yeast for Incorporation of Diverse Unnatural Amino Acids via a Pyrrolysyl-tRNA Synthetase/tRNA Pair

We report the discovery of a simple system through which variant pyrrolysyl-tRNA synthetase/tRNACUAPyl pairs created in Escherichia coli can be used to expand the genetic code of Saccharomyces cerevisiae. In the process we have solved the key challenges of producing a functional tRNACUAPyl in yeast and discovered a pyrrolysyl-tRNA synthetase/tRNACUAPyl pair that is orthogonal in yeast. Using our approach we have incorporated an alkyne-containing amino acid for click chemistry, an important post-translationally modified amino acid and one of its analogs, a photocaged amino acid and a photo-cross-linking amino acid into proteins in yeast. Extensions of our approach will allow the growing list of useful amino acids that have been incorporated in E. coli with variant pyrrolysyl-tRNA synthetase/tRNACUAPyl pairs to be site-specifically incorporated into proteins in yeast.
Alcohol-antiretroviral therapy interactive toxicity beliefs and daily medication adherence and alcohol use among people living with HIV

ABSTRACT Alcohol-antiretroviral therapy (ART) interactive toxicity beliefs reflect perceived adverse outcomes of mixing alcohol and ART. Previous research has shown a significant relationship between alcohol-ART interactive toxicity beliefs and ART non-adherence, over and above other correlates of non-adherence such as human immunodeficiency virus (HIV)symptoms and frequency of alcohol use. Most past studies have collected data over extended periods and have not determined if alcohol use and missed medications occur at the day-level among people holding interactive toxicity beliefs. Previous daily analyses, however, have been limited by self-reported adherence and relatively short periods of observation. To address these gaps in the literature, men and women living with HIV in Atlanta, GA, were enrolled in a 45-day observational cohort study. Daily alcohol use was collected using two-way interactive text message surveys and daily adherence was collected via the Wisepill device. Fifty-seven participants completed a measure of alcohol-ART interactive toxicity beliefs and contributed 2565 days of daily data. Participants who endorsed high levels of interactive toxicity beliefs had significantly more days when they missed doses of medication. Alcohol-antiretroviral toxicity beliefs predicted missing doses of medication on days when participants were drinking and on days when they were not drinking. Multilevel multivariate regressions showed that these toxicity beliefs predicted daily missed doses of medication over and above quantity of alcohol consumed, depression and general medication concerns. This study replicates and extends previous literature and indicates the necessity of addressing alcohol-ART toxicity beliefs within adherence interventions.
An Improved Quasi-Orthogonal Space-Time Block Codes for Diversity Reception in Wireless Communication

Quasi orthogonal space time block codes have been proposed to achieve higher symbol transmission rates for more than 2 transmit antennas at the expense of losing the diversity gain. In this paper we propose a method to improve its transmit diversity with one bit feedback. This method useful for extend any space-time code constructed for 4 transmit antennas to M receive antennas. An improvement in transmit diversity is achieved by multiplying each QOSTBC code word with appropriate phase factor which depend on the channel information. Jafarkhani’s Quasi Orthogonal Space Time Block Codes as well as its optimal constellation rotated scheme are extended and analyzed.
AMULET2e: an asynchronous embedded controller

AMULETI demonstrated the feasibility of building an asynchronous implementation of the ARM microprocessor. Although functional, this first asynchronous ARM microprocessor did not fully exploit the potential of the asynchronous design style to deliver improved performance and power consumption. This paper describes AMULET2e, an embedded system chip incorporating an enhanced asynchronous ARM core (AMULET2), a 4 Kbyte pipelined cache, a flexible memory interface and assorted programmable control functions. AMULET2e silicon demonstrates competitive performance and power-efficiency, ease of design, and innovative features that exploit its asynchronous operation to advantage in power-sensitive applications.
An Assessment of Written Responses to Conflict Imagery by Northern Ireland Art and Non-Art Students

This study examines the written responses of art and non-art students in Northern Ireland to a series of images related to conflict using Stavropoulos' (1992) Diagnostic Profile (DP). Stavropoulos' instrument is primarily designed to offer a more complex and nuanced insight into the analysis of art images using four dimensions: descriptive, formal, interpretative, and historical. It is evident that even though the art students achieve overall higher scores than the non-art students, it might have been expected that they would have shown greater evidence of more specific knowledge-based elements in their accounts. This finding might imply that the delivery of the art curriculum in Northern Ireland pays insufficient attention to the formal and historical aspects of the subject, but rather has encouraged the students to rely on more descriptive and interpretative judgments which are insufficiently rooted in the formal traditions of the subject. This study also uses an additional fifth social/psychological dimension, developed by the present researcher, to identify the social attributions and coping strategies used by children affected by the conflict in Northern Ireland. Specifically, this study scrutinizes the social attributions of 159 Protestant and Catholic art and non-art high school students living in real conflict zones of Belfast. The findings suggest that there is a proliferation of fear, harm and loss attributions in the children's written responses. Related to this is the extent to which attributions reflecting outgroup/ingroup themes and issues related to religious/ideological support, stereotyping and social representation categorizations are also present. It is also apparent that some children possess something that is akin to a ”political” intelligence. The findings also imply that some children use coping strategies to live in what Rackstraw (2001) refers to as ”idealized worlds”. It may be that the evidence of these themes is related to psychological needs arising from living in, or being close to, areas of political conflict.
Three-body equations of motion in successive post-Newtonian approximations

There are periodic solutions to the equal-mass three-body (and N-body) problem in Newtonian gravity. The figure-eight solution is one of them. In this paper, we discuss its solution in the first and second post-Newtonian approximations to general relativity. To do so we derive the canonical equations of motion in the ADM gauge from the three-body Hamiltonian. We then integrate those equations numerically, showing that quantities such as the energy, linear and angular momenta are conserved down to numerical error. We also study the scaling of the initial parameters with the physical size of the triple system. In this way we can assess when general relativistic results are important and we determine that this occurs for distances of the order of 100M, with M the total mass of the system. For distances much closer than those, presumably the system would completely collapse due to gravitational radiation. This sets up a natural cut-off to Newtonian N-body simulations. The method can also be used to dynamically provide initial parameters for subsequent full nonlinear numerical simulations.
WHAT IS THE OPTIMAL NUMBER OF TRAITS TO DESCRIBE PSYCHOPATHY

Hare΄s Psychopathy Check List – Revised (PCL-R) represents one of the most frequently used instruments for measuring psychopathy. However, there is a dispute regarding the optimal number of factors that configure its latent structure. Previous research in Serbia has shown that several tested models did not fit well with the empirical data. In this study, we have gathered and analyzed all of the available data on PCL-R collected in Serbia (406 male convicts, mean age 34 years, SD = 9.98). Exploratory factor analysis has shown that the variance of the scale items could be best explained with five latent components: Interpersonal, Affective, Impulsivity, Lifestyle and Antisocial. Several structural models were tested as well, with a special focus on two of them: the first where all of the traits are treated equally, and the second where Lifestyle and Antisocial traits were set as behavioral outcomes of the three personality traits. The second model surpassed not only the first one, but its fit indices showed a better fit than any of the other models proposed in literature. The results of the present research support models that describe psychopathy as a compound of three core traits: manipulative tendencies, affective superficiality and impulsiveness.
Human Papillomavirus Genotype Distributions: Implications for Vaccination and Cancer Screening in the United States

Background Limited data are available describing human papillomavirus (HPV) genotype distributions in cervical cancer in the United States. Such studies are needed to predict how HPV vaccination and HPV-based screening will influence cervical cancer prevention. Methods We used the New Mexico Surveillance, Epidemiology, and End Results Registry to ascertain cases of in situ (n = 1213) and invasive (n = 808) cervical cancer diagnosed during 1985–1999 and 1980–1999, respectively, in the state of New Mexico. HPV genotyping was performed using two polymerase chain reaction–based methods on paraffin-embedded tissues from in situ and invasive cancers and on cervical Papanicolaou test specimen from control subjects (ie, women aged 18–40 years attending clinics for routine cervical screening [n = 4007]). Relative risks for cervical cancer were estimated, and factors associated with age at cancer diagnosis and the prevalence of HPV genotypes in cancers were examined. Results The most common HPV genotypes detected in invasive cancers were HPV type 16 (HPV16, 53.2%), HPV18 (13.1%), and HPV45 (6.1%) and those in in situ cancers were HPV16 (56.3%), HPV31 (12.6%), and HPV33 (8.0%). Invasive cancer case subjects who were positive for HPV16 or 18 were diagnosed at younger ages than those who were positive for other carcinogenic HPV genotypes (mean age at diagnosis: 48.1 [95% confidence interval {CI} = 46.6 to 49.6 years], 45.9 [95% CI = 42.9 to 49.0 years], and 52.3 years [95% CI = 50.0 to 54.6 years], respectively). The proportion of HPV16-positive in situ and invasive cancers, but not of HPV18-positive cancers, declined with more recent calendar year of diagnosis, whereas the proportion positive for carcinogenic HPV genotypes other than HPV18 increased. Conclusions HPV16 and 18 caused the majority of invasive cervical cancer in this population sample of US women, but the proportion attributable to HPV16 declined over the last 20 years. The age at diagnosis of HPV16- and HPV18-related cancers was 5 years earlier than that of cancers caused by carcinogenic HPV genotypes other than HPV16 and 18, suggesting that the age at initiation of cervical screening could be delayed in HPV-vaccinated populations.
A map based on laserscans without geometric interpretation

A map for an autonomous mobile robot (AMR) in an indoor environment for the purpose ofcontinuous position and orientation estimation is discussed. Unlike many other approaches, this map is not based on geometrical primitives like lines and polygons. An algorithm is shown , where the sensordata of a laser range finder can be used to establish this map without a geometrical interpretation of the data. This is done by converting single laser radar scans to statistical representations of the environ-ment, so that a crosscorrelation of an actu al converted scan and this representative results into the actual position and orientation in a global coordinate system. The map itsel f is build of representative scansfor the positions where the AMR has been, so that it is able to find its position and orientation by c omparing the actual scan with a scan stored in the map.
Hypertext authoring and visualization

Visualizing information structure plays an increasing role in hypertext systems. Empirical evidence shows that such visualizations support the users or readers of hypertext systems. The following study investigates whether such information visualizations in the form of two-dimensional graphical overview maps also support the writers of hypertext documents. It also seems plausible to assume that the process of writing text changes when graphical overview maps integrated into hypertext systems are used. We also analysed the relationship between the authoring process and the character of the finished documents. In general, it can be said that visualizing the information structure inherent in a document plays an important role in hypertext authoring. It was the only innovative feature of the hypertext authoring system we developed which was used intensively by almost all the authors. In contrast to that, the finished documents were rather traditional. Authors did not exploit the novel features of hypertext/hypermedia systems like, e.g. introducing pictures, movies or sounds. On the basis of the analysis of the hypertext authoring process guidelines can be formulated to support writers of hypertext documents.
Cerebrovascular Effects of Rapid Volume Expansion in Preterm Fetal Sheep

Preterm human infants are often treated with volume expansion during their initial stabilization. There are limited data regarding the cerebral vascular effects of this therapeutic approach. The effects of blood volume expansion on cerebral vascular reactivity and oxygen metabolism in very immature animals have not been determined. We examined the effects of volume expansion, with and without hypoxia, on cerebral blood flow and metabolism in unanesthetized, chronically catheterized, preterm fetal sheep. Rapid volume expansion with i.v. dextran increased circulating blood volume. Arterial blood pressure did not increase, nor did cerebral blood flow. However, volume expansion resulted in lower arterial Hb concentration and, consequently, oxygen content without a compensatory increase in cerebral blood flow. Cerebral oxygen delivery fell significantly. Induction of severe hypoxia after volume expansion resulted in an increase in cerebral blood flow, as expected, but the increase in flow was not enough to maintain cerebral oxygen delivery. Rapid volume expansion in normovolemic preterm fetal sheep is associated with decreased cerebral oxygen delivery, and this is further compromised when oxygen content is decreased.
Analysis of Correlated Shadow Fading in Dual-Link Indoor Radio Wave Propagation

In this letter, we analyze the results of dynamic, double-directional, dual-link channel sounding, where the measurement system consists of one transmitter moving along a continuous route and two fixed receivers. The results show that despite a large terminal separation at one side of the link, the fading behaviors of the two links can be strongly correlated. In this special case, correlated shadow fading was found to be caused by the similar initial signal directions at the transmitter side and due to pillars that shadowed the signals at that side of the link. The fading phenomenon has been analyzed by dividing the received power into groups of multipath components revealing similar propagation mechanisms and by investigating the properties of those multipath components that are most severely shadowed by the pillars.
Program Demultiplexing: Data-flow based Speculative Parallelization of Methods in Sequential Programs

We present program demultiplexing (PD), an execution paradigm that creates concurrency in sequential programs by "demultiplexing" methods (functions or subroutines). Call sites of a demultiplexed method in the program are associated with handlers that allow the method to be separated from the sequential program and executed on an auxiliary processor. The demultiplexed execution of a method (and its handler) is speculative and occurs when the inputs of the method are (speculatively) available, which is typically far in advance of when the method is actually called in the sequential execution. A trigger, composed of predicates that are based on program counters and memory write addresses, launches the speculative execution of the method on another processor. Our implementation of PD is based on a full-system execution-based chip multi-processor simulator with software to generate triggers and handlers from an x86-program binary. We evaluate eight integer benchmarks from the SPEC2000 suite - programs written in C with no explicit concurrency and/or motivation to create concurrency - and achieve a harmonic mean speedup of 1.8x with our implementation of PD
Transducing by Observing

The paradigm of Computing by Observing, so far used for generating and accepting languages, is extended to transductions. We show that only string-rewriting rules of the form a→ b suffice to compute most rational and pushdown relations. Only pairs with empty left-hand side cause problems. Even non-pushdown relations can be computed, namely a test for prime numbers can be implemented.
Cytokines, Chemokines, and Growth Factors in Banked Human Donor Milk for Preterm Infants

Background: There has been a recent increase in availability of banked donor milk for feeding of preterm infants. This milk is pooled from donations to milk banks from carefully screened lactating women. The milk is then pasteurized by the Holder method to remove all microbes. The processed milk is frozen, banked, and sold to neonatal intensive care units (NICUs). The nutrient bioavailability of banked donor milk has been described, but little is known about preservation of immune components such as cytokines, chemokines, and growth factors (CCGF). Objective: The objective was to compare CCGF in banked donor milk with mother’s own milk (MOM). Methods: Aliquots (0.5 mL) were collected daily from MOM pumped by 45 mothers of NICU-admitted infants weighing < 1500 grams at birth. All daily aliquots of each mother’s milk were pooled each week during 6 weeks of an infant’s NICU stay or for as long as the mother provided MOM. The weekly pooled milk was measured for a panel of CCGF through multiplexing using magnetic beads and a MAGPIX instrument. Banked donor milk samples (n = 25) were handled and measured in the same way as MOM. Results: Multiplex analysis revealed that there were levels of CCGF in banked donor milk samples comparable to values obtained from MOM after 6 weeks of lactation. Conclusion: These data suggest that many important CCGF are not destroyed by Holder pasteurization.
Characterization of the in Vitro Effects of Glucocorticosteroids on NK Cell Activity

The NK cell activity of mononuclear cells as well as monocyte‐depleted, Percoll‐fractionated, NK cell‐enriched effector cells against K 562 target cells was inhibited by methylprednisolone (MP) and hydrocortisone (HC) in a dose‐dependent manner. The effector/target cell conjugate formation was studied in a single cell agarose assay, and it was shown that MP and HC partly inhibited the NK cell activity by inhibition of the adhesion of effector cells to target.
Exploitation of Parasitic Smart Antennas in Wireless Sensor Networks

The integration of smart antennas in wireless sensor networks is a challenging and very attractive technical solution to improve the system capacity, the quality of service, and the power control. In this paper, some benefits coming from such an integration are experimentally assessed dealing with a set of test scenarios. Finally, some conclusions are discussed in order to point out current potentialities and limitations of the smart antennas integration to envisage future and possible advances.
Blood vessel segmentation in retinal images using echo state networks

We propose a novel supervised technique for blood vessel segmentation in retinal images based on echo state networks. Retinal vessel segmentation is widely used for numerous clinical purposes such as the detection of various cardiovascular and ophthalmologic diseases. A large number of retinal vessel segmentation methods have been reported, yet achieving accurate and efficient vessel segmentation still remains a challenge. Recently, reservoir computing has drawn much attention as a new computing framework based on recurrent neural networks. The Echo State Network (ESN), which uses neural nodes as the computing elements of the recurrent network, represents one of the efficient learning models of reservoir computing. This paper investigates the viability of echo state networks for blood vessel segmentation in retinal images. Initial image features are projected onto the echo state network reservoir which maps them, through its internal nodes activations, into a new set of features to be classified into vessel or non-vessel by the echo state network readout which consists, in the proposed approach, of a multi-layer perceptron. Experimental results on the publicly available DRIVE dataset, commonly used in retinal vessel segmentation research, demonstrate the ability of the proposed method in achieving promising performance results in terms of both segmentation accuracy and efficiency.
