Predicting Repetition of Suicide Attempt: A Prospective Study of 50Suicide Attempters

The purpose of this study was to identify risk factors for repetition of suicide attempt by means of a prospective design. Fifty suicide attempters were interviewed shortly after their attempt and then 18 months later. During this time period, eight persons had repeated their suicide attempt. Logistic regression analyses showed that low self-appraised problem-solving capacity and general self-efficacy predicted repetition of attempt. No significant effects were found from depression, hopelessness or self-esteem. Moreover, self-appraised problem-solving capacity and self-efficacy retained their predictive power even when controlling for sex, age, previous suicide attempt, suicide intention and medical risk. The single most important predictor of repeated suicide attempt was found to be low self-efficacy; a change of one standard deviation yielded an odds ratio of 3.7.
A Distributed Route Structure Based on IPv6 in P2P System

A hierarchy distributed route structure based on IPv6 address in peer to peer systems is proposed in order to solve the problems that physical topology and logical network does not match so as to inefficient search in distributed hash table at present. By building node identifier using IPv6 address and hashing different level clustering identifier to set up hierarchy route, near nodes in physical network are closer in overlay. Smaller hops across domain, lower search latency, and higher efficiency are proved.
Concentration in unbounded metric spaces and algorithmic stability

We prove an extension of McDiarmid's inequality for metric spaces with unbounded diameter. To this end, we introduce the notion of the subgaussian diameter, which is a distribution-dependent refinement of the metric diameter. Our technique provides an alternative approach to that of Kutin and Niyogi's method of weakly difference-bounded functions, and yields nontrivial, dimension-free results in some interesting cases where the former does not. As an application, we give apparently the first generalization bound in the algorithmic stability setting that holds for unbounded loss functions. This yields a novel risk bound for some regularized metric regression algorithms. We give two extensions of the basic concentration result. The first enables one to replace the independence assumption by appropriate strong mixing. The second generalizes the subgaussian technique to other Orlicz norms.
Sociologist unbound: A celebration of the work of Jacklyn Cock

Abstract We are gathered here today to celebrate the work of Jacklyn Cock. It is a time to rejoice publicly at a working life of exceptional creativity. This is a happy event. I have used the verb unbound in the title of this introduction to the working life of Jackie as hers is a career that has not been tied down by conventional notions of what role a middle class white women sociologist ought to play. Instead she has crossed the boundaries of race, of gender and, above all, the boundary that separates academic theory and research from the transformation of the lives of ordinary people. This direct link between scholarly research and social activism and advocacy is what makes her working life exceptional.
Identification of Tam41 maintaining integrity of the TIM23 protein translocator complex in mitochondria

Newly synthesized mitochondrial proteins are imported into mitochondria with the aid of protein translocator complexes in the outer and inner mitochondrial membranes. We report the identification of yeast Tam41, a new member of mitochondrial protein translocator systems. Tam41 is a peripheral inner mitochondrial membrane protein facing the matrix. Disruption of the TAM41 gene led to temperature-sensitive growth of yeast cells and resulted in defects in protein import via the TIM23 translocator complex at elevated temperature both in vivo and in vitro. Although Tam41 is not a constituent of the TIM23 complex, depletion of Tam41 led to a decreased molecular size of the TIM23 complex and partial aggregation of Pam18 and -16. Import of Pam16 into mitochondria without Tam41 was retarded, and the imported Pam16 formed aggregates in vitro. These results suggest that Tam41 facilitates mitochondrial protein import by maintaining the functional integrity of the TIM23 protein translocator complex from the matrix side of the inner membrane.
Mode Discrimination Abilities of Pre-School Children

The purpose of the study was to investigate young children's ability to perceive mode changes in music and to identify major and minor stimuli. Children received short training in the use of the words "major" and "minor" and their application to music. In the post-test, subjects listened to a children's song which presented eight mode changes. They were asked to (1) clap (Pilot Study) or move (Main Study) when they heard a change in the music, and (2) label the major and minor fragments of the song. Results of the Pilot Study showed that kindergarten children (5-year-olds) identified mode changes more accurately than pre-school children (4-year-olds) and were able to perceive more than half of the mode changes when using the terms "major" and "minor". Song familiarity did not affect children's performance in thd test. The Main Study corroborated kindergarten children's ability to perceive mode changes. It also showed that children were able to express their perception better through verbal than non-verbal responses.
Enterotoxigenic and non-enterotoxigenic Bacteroides fragilis from fecal microbiota of children

Enterotoxigenic Bacteroides fragilis (ETBF) is an important part of the human and animal intestinal microbiota and is commonly associated with diarrhea. ETBF strains produce an enterotoxin encoded by the bft gene located in the B. fragilis pathogenicity island (BfPAI). Non-enterotoxigenic B. fragilis (NTBF) strains lack the BfPAI and usually show two different genetic patterns, II and III, based on the absence or presence of a BfPAI-flanking region, respectively. The incidence of ETBF and NTBF strains in fecal samples isolated from children without acute diarrhea or any other intestinal disorders was determined. All 84 fecal samples evaluated were B. fragilis-positive by PCR, four of them harbored the bft gene, 27 contained the NTBF pattern III DNA sequence, and 52 were considered to be NTBF pattern II samples. One sample was positive for both ETBF and NTBF pattern III DNA sequences. All 19 B. fragilis strains isolated by the culture method were bft-negative, 9 belonged to pattern III and 10 to pattern II. We present an updated overview of the ETBF and NTBF incidence in the fecal microbiota of children from Sao Paulo City, Brazil.
A fast cube-based video shot retrieval using 3D moment-preserving technique

In this paper, we describe a novel video shot retrieval where each shot is separated into multiple video cubes. Therefore, every video shot can be represented by a linear combination of video cubes, which are used to calculate the similarity measurements among video shots in terms of video cube similarity. The position of a voxel in a cube is characterized with (x, y, t) 3D coordinates and the spatial-temporal features within video cubes are extracted with a set of analytical formulas derived from the proposed 3D moment-preserving technique. Then, the content of a video cube is approximated by three blocks generated from projecting the cube onto xy, yt and tx planes. Based on the visual patterns of xy, yt, and tx blocks, a fast video shot retrieval scheme is proposed. As compared with other key-frame based representations, the proposed cube-based video retrieval improves the retrieval accuracy without sacrificing the execution speed. Experimental results show the efficiency and effectiveness of the proposed video retrieval.
XPath-Wrapper Induction by generating tree traversal patterns

We introduce a wrapper induction algorithm for extracting information from tree-structured documents like HTML or XML. It derives XPath-compatible extraction rules from a set of annotated example documents. The approach builds a minimally generalized tree traversal pattern, and augments it with conditions. Another variant selects a subset of conditions so that (a) the pattern is consistent with the training data, (b) the pat-tern's document coverage is minimized, and (c) conditions that match structures preceding the target nodes are preferred. We discuss the ro-bustness of rules induced by this selection strategy and we illustrate how these rules exhibit knowledge of the target concept.
Responses to Sibling Sexual Abuse: Are They as Harmful as the Abuse?

Abstract The present paper reports on an exploratory qualitative study of 19 women on the reactions of those the women encountered in their everyday lives—family, professionals, and community members—when they became aware that the women were survivors of sibling sexual abuse. The study asked whether negative attitudes towards sibling sexual abuse were as harmful as the abuse experience. Data were collected from three focus group discussions and taped transcripts were analysed in terms of themes in public discourse on sibling sexual abuse. The aim of the study was to increase understanding of the impact of people's attitudes and responses to this phenomenon. The findings highlighted the harmful impact of negative attitudes that are reinforced by public discourse that generally fails to problematise the issue and the need for education in professional, community, and school settings.
Smart Gossip: An Adaptive Gossip-based Broadcasting Service for Sensor Networks

A network-wide broadcast service is often used for information dissemination in sensor networks. Sensor networks are typically energy-constrained and prone to failures. In view of these constraints, the broadcast service should minimize energy consumption by reducing redundant transmissions, and be tolerant to frequent node and link failures. We propose "smart gossip", a probabilistic protocol that offers a broadcast service with low overheads. Smart gossip automatically and dynamically adapts transmission probabilities based on the underlying network topology. The protocol is capable of coping with wireless losses and unpredictable node failures that affect network connectivity over time. The resulting protocol is completely decentralized. We present thorough experimental results to evaluate our "smart gossip" proposal, and demonstrate its benefits over existing protocols
Mao and Chinese Elite Politics in the 1950s: The Gao Gang Affair Revisited

Abstract:Based on recently available new evidence, this study revisits the Gao Gang affair in the early 1950s, with an emphasis on Mao's role in manipulating elite politics as a way of strengthening his charismatic leadership. The CCP elite politics in the early 1950s were in essence "court politics" centered on and manipulated by Mao. Afraid of being sidelined by Beijing's "managerial elite" in economic reconstruction, Mao promoted Gao and other regional leaders, while stripping powers from Liu, Zhou, and their associates. By the end of 1953, Mao started to suspect Gao's loyalty and Gao's promotion backfired. Mao quickly abandoned Gao and isolated him, Gao's downfall was as quick and sudden as his rise. Mao's chief concern was none other than the enhancement and strengthening of the belief in his infallibility, which was the foundation of his charismatic authority.
Bidimensionality and geometric graphs

In this paper we use several of the key ideas from Bidimensionality to give a new generic approach to design EPTASs and subexponential time parameterized algorithms for problems on classes of graphs which are not minor closed, but instead exhibit a geometric structure. In particular we present EPTASs and subexponential time parameterized algorithms for Feedback Vertex Set, Vertex Cover, Connected Vertex Cover, Diamond Hitting Set, on map graphs and unit disk graphs, and for Cycle Packing and Minimum-Vertex Feedback Edge Set on unit disk graphs. Our results are based on the recent decomposition theorems proved by Fomin et al [SODA 2011], and our algorithms work directly on the input graph. Thus it is not necessary to compute the geometric representations of the input graph. To the best of our knowledge, these results are previously unknown, with the exception of the EPTAS and a subexponential time parameterized algorithm on unit disk graphs for Vertex Cover, which were obtained by Marx [ESA 2005] and Alber and Fiala [J. Algorithms 2004], respectively. We proceed to show that our approach can not be extended in its full generality to more general classes of geometric graphs, such as intersection graphs of unit balls in R^d, d >= 3. Specifically we prove that Feedback Vertex Set on unit-ball graphs in R^3 neither admits PTASs unless P=NP, nor subexponential time algorithms unless the Exponential Time Hypothesis fails. Additionally, we show that the decomposition theorems which our approach is based on fail for disk graphs and that therefore any extension of our results to disk graphs would require new algorithmic ideas. On the other hand, we prove that our EPTASs and subexponential time algorithms for Vertex Cover and Connected Vertex Cover carry over both to disk graphs and to unit-ball graphs in R^d for every fixed d.
An improved soft decision based noise power estimation employing adaptive prior and conditional smoothing

In this paper, a new approach is proposed to improve a sigmoid and conditional smoothing-based speech presence probability (SPP) method for noise power spectral density (PSD) estimation. In this approach, the a posteriori speech absence probability (SAP) is adapted with a sigmoid function mapped to the normalised spectral average variance in the consecutive frames that can effectively characterise noise variation. The adaptation is also employed in the conditional smoothing stage to characterise the a posteriori SPP, which is then utilised in the noise PSD estimation. Comparison with state of the art methods validates the effectiveness of the proposed method.
IEPs in mainstream secondary schools: an agenda for research

Providing children with special educational needs with individual education plans (IEPs) was advocated in the 1994 code of practice for SEN, and retained in the 2000 code. Specifically as it relates to mainstream secondary schools, this has proved highly controversial: many SENCos report that the writing and implementing of IEPs is a bureaucratic encumbrance, whilst others, going about the process of writing IEPs in very different ways, report that the process is both manageable and beneficial to the children concerned. Given this contradictory evidence, there is an urgent need for research into this area. Having looked at three case-studies of schools using very different methods to write IEPs in ways with which they feel comfortable, a research agenda is set out with a view to informing policies which ensure that resources spent on SEN are used as productively as possible.
New Gastropod Vectors and Tetrodotoxin Potential Expansion in Temperate Waters of the Atlantic Ocean

Tetrodotoxin is a potent low weight marine toxin found in warm waters, especially of the Indian and Pacific Oceans. Intoxications are usually linked to the consumption of the puffer fish, although TTX was already detected in several different edible taxa. Benthic organisms such as mollusks and echinoderms, with different feeding habits, were collected monthly along the Portuguese coast from the summer of 2009 until the end of 2010. The extraction and analysis techniques were optimized and TTX and some analogues were detected for the first time in two intertidal gastropod species—Gibbula umbilicalis and Monodonta lineata by LC-MS/MS and UPLC-MS/MS. Although the levels are low, these findings suggest that monitoring of TTX and analogues in North Atlantic species should be implemented so as to detect potentially new toxin vectors and seasonal and/or geographical patterns.
Image and video fingerprinting: forensic applications

Fighting movie piracy often requires automatic content identification. The most common technique to achieve this uses watermarking, but not all copyrighted content is watermarked. Video fingerprinting is an efficient alternative solution to identify content, to manage multimedia files in UGC sites or P2P networks and to register pirated copies with master content. When registering by matching copy fingerprints with master ones, a model of distortion can be estimated. In case of in-theater piracy, the model of geometric distortion allows the estimation of the capture location. A step even further is to determine, from passive image analysis only, whether different pirated versions were captured with the same camcorder. In this paper we present three such fingerprinting-based forensic applications: UGC filtering, estimation of capture location and source identification.
Rapid and long‐term alterations of hippocampal GABAB receptors in a mouse model of temporal lobe epilepsy

Alterations of γ‐aminobutyric acid (GABA)B receptor expression have been reported in human temporal lobe epilepsy (TLE). Here, changes in regional and cellular expression of the GABAB receptor subunits R1 (GBR1) and R2 (GBR2) were investigated in a mouse model that replicates major functional and histopathological features of TLE. Adult mice received a single, unilateral injection of kainic acid (KA) into the dorsal hippocampus, and GABAB receptor immunoreactivity was analysed between 1 day and 3 months thereafter. In control mice, GBR1 and GBR2 were distributed uniformly across the dendritic layers of CA1–CA3 and dentate gyrus. In addition, some interneurons were labelled selectively for GBR1. At 1 day post‐KA, staining for both GBR1 and GBR2 was profoundly reduced in CA1, CA3c and the hilus, and no interneurons were visible anymore. At later stages, the loss of GABAB receptors persisted in CA1 and CA3, whereas staining increased gradually in dentate gyrus granule cells, which become dispersed in this model. Most strikingly, a subpopulation of strongly labelled interneurons reappeared, mainly in the hilus and CA3 starting at 1 week post‐KA. In double‐staining experiments, these cells were selectively labelled for neuropeptide Y. The number of GBR1‐positive interneurons also increased contralaterally in the hilus. The rapid KA‐induced loss of GABAB receptors might contribute to epileptogenesis because of a reduction in both presynaptic control of transmitter release and postsynaptic inhibition. In turn, the long‐term increase in GABAB receptors in granule cells and specific subtypes of interneurons may represent a compensatory response to recurrent seizures.
Temporal Perceptual Learning

Our interaction with the environment and each other is inherently time-varying in nature. It is thus not surprising that the nervous systems of animals have evolved sophisticated mechanisms to not only tell time, but to learn to discriminate and produce temporal patterns. Indeed some of the most sophisticated human behaviors, such as speech and music, would not exist if the human brain was unable to learn to discriminate and produce temporal patterns. Compared to the study of other forms of learning, such as visual perceptual learning, the study of the learning of interval and temporal pattern discrimination in the subsecond range is relatively recent. A growing number of studies over the past 15 years, however, have established that perceptual and motor timing undergo robust learning. One of the principles to have emerged from these studies is that temporal learning is generally specific to the trained interval, an observation that has important implications to the neural mechanisms underlying our ability to tell time.
Quantitative Characterization of Collagen in the Fibrotic Capsule Surrounding Implanted Polymeric Microparticles through Second Harmonic Generation Imaging

The collagenous capsule formed around an implant will ultimately determine the nature of its in vivo fate. To provide a better understanding of how surface modifications can alter the collagen orientation and composition in the fibrotic capsule, we used second harmonic generation (SHG) microscopy to evaluate collagen organization and structure generated in mice subcutaneously injected with chemically functionalized polystyrene particles. SHG is sensitive to the orientation of a molecule, making it a powerful tool for measuring the alignment of collagen fibers. Additionally, SHG arises from the second order susceptibility of the interrogated molecule in response to the electric field. Variation in these tensor components distinguishes different molecular sources of SHG, providing collagen type specificity. Here, we demonstrated the ability of SHG to differentiate collagen type I and type III quantitatively and used this method to examine fibrous capsules of implanted polystyrene particles. Data presented in this work shows a wide range of collagen fiber orientations and collagen compositions in response to surface functionalized polystyrene particles. Dimethylamino functionalized particles were able to form a thin collagenous matrix resembling healthy skin. These findings have the potential to improve the fundamental understanding of how material properties influence collagen organization and composition quantitatively.
The Impact of Group Membership on Collaborative Learning with Wikis

The social web stimulates learning through collaboration. However, information in the social web is often associated with information about its author. Based on previous evidence that ingroup information is preferred to outgroup information, the current research investigates whether group memberships of wiki authors affect learning. In an experimental study, we manipulated the group memberships (ingroup vs. outgroup) of wiki authors by using nicknames. The designated group memberships (being fans of a soccer team or not) were completely irrelevant for the domain of the wiki (the medical disorder fibromyalgia). Nevertheless, wiki information from the ingroup led to more integration of information into prior knowledge as well as more increase of factual knowledge than information from the outgroup. The results demonstrate that individuals apply social selection strategies when considering information from wikis, which may foster, but also hinder, learning and collaboration. Practical implications for collaborative learning in the social web are discussed.

The ‘success’ image of Asian Americans: Its validity, and its practical and theoretical implications 1

Abstract The success stereotype of Asian Americans is examined in terms of three major research questions. (1) What factors account for the vicissitudes of the dominant group's perception of Asian Americans since 1850? (2) To what extent is the current success image of Asian Americans true? (3) How would such a model minority image affect Asian Americans, the other minorities, and majority Americans? The first question is addressed by historical data, and the second and third questions are answered by analyses of census data supplemented by other empirical data on Asian Americans. Factors accounting for the changes of the dominant group's image of Asian Americans are found to be primarily situational, and our analyses in the light of the principle of earnings equity indicate that the success image is largely a myth due to labour market disadvantages and other related social problems. Practical and theoretical implications are discussed in the conclusion.
