BEAR: Block Elimination Approach for Random Walk with Restart on Large Graphs

Given a large graph, how can we calculate the relevance between nodes fast and accurately? Random walk with restart (RWR) provides a good measure for this purpose and has been applied to diverse data mining applications including ranking, community detection, link prediction, and anomaly detection. Since calculating RWR from scratch takes long, various preprocessing methods, most of which are related to inverting adjacency matrices, have been proposed to speed up the calculation. However, these methods do not scale to large graphs because they usually produce large and dense matrices which do not fit into memory. In this paper, we propose BEAR, a fast, scalable, and accurate method for computing RWR on large graphs. BEAR comprises the preprocessing step and the query step. In the preprocessing step, BEAR reorders the adjacency matrix of a given graph so that it contains a large and easy-to-invert submatrix, and precomputes several matrices including the Schur complement of the submatrix. In the query step, BEAR computes the RWR scores for a given query node quickly using a block elimination approach with the matrices computed in the preprocessing step. Through extensive experiments, we show that BEAR significantly outperforms other state-of-the-art methods in terms of preprocessing and query speed, space efficiency, and accuracy.
Detection and Characterization of Fungal-Specific Proteins in Saccharomyces cerevisiae

In this study, I searched for fungal-specific proteins in the genome of the budding yeast Saccharomyces cerevisiae, inferred from a comparison of amino acid sequences. I used the GTOP (Genomes to Protein structures and functions) database of the DDBJ (DNA Data Bank of Japan), which consists of 21 genomes from Archaea, 203 genomes from Bacteria, and 50 genomes from Eucarya (including 18 fungal genomes). Among 5,874 proteins of S. cerevisiae, 1,551 have homologs only in Eucarya, and 504 of the 1,551 have homologs only in fungi. To find fungal-specific proteins, homologs of the homologs have been searched repeatedly. As a result, 132 of the 504 are characterized as fungal-specific proteins. The genes encoding the 132 fungal-specific proteins are not included in the list of essential genes for viability in the S. cerevisiae genome deletion project. Among the 132 proteins, 99 are S. cerevisiae-specific, and no protein that is distributed among 10 or more of the 18 fungal species exists. In addition, most of the fungal-specific proteins are very small and functionally unknown. My results show that the fungal-specific proteins have short evolutionary histories, suggesting that S. cerevisiae produces novel proteins and that ancestral fungi also produced small proteins most of which have disappeared or have been combined with other proteins during fungal evolution.
Personality Disorder and Psychopathy as Predictors of Psychosocial and Criminological Outcome in Mentally Disordered Offenders

Ninety-five patients discharged from a specialist Personality Disorder (PD) service were prospectively assessed for Axis II disorders and Psychopathy. Sequential regression models tested the ability of different conceptual definitions of PD and Psychopathy to predict criminological and psychosocial outcome over a mean follow-up of 4.16 years. Trait definitions of PD modestly predicted criminological outcome. After controlling for age, IQ and PD, time to first reconviction after entering the community was predicted by PCL-R Factors 1, 2, and previous convictions. Psychosocial outcome was predicted by PCL-R with high scores on the affective-interpersonal Factor 1 providing strongest prediction of poor psychosocial outcome.

Clinical Practice and Epidemiology in Mental Health Add-on Quetiapine in the Treatment of Major Depressive Disorder in Elderly Patients with Cerebrovascular Damage

Background: Depressive episodes in elderly patients with cerebrovascular damage are characterized by poor responses to standard antidepressants. Recent reports have suggested that the atypical antipsychotic, quetiapine may have antidepressant properties and, in mice, may prevents memory impairment and hippocampus neurodegeneration induced by global cerebral ischemia.
Continuous-Discrete Observer for State Affine Systems With Sampled and Delayed Measurements

The observation of a class of multi-input multi-output (MIMO) state affine systems with both sampled and delayed output measurements is addressed. These two constraints disturb simultaneously the convergence of the observer. Assuming some persistent excitation conditions to hold, and by using Lyapunov tools adapted to impulsive systems, two classes of global exponential observers are proposed. Some explicit relations between maximum allowable delay and maximum allowable sampling period are given. An extension to some classes of nonlinear systems is also given.
A Post-Hospital Home Exercise Program Improved Mobility but Increased Falls in Older People: A Randomised Controlled Trial

Background Home exercise can prevent falls in the general older community but its impact in people recently discharged from hospital is not known. The study aimed to investigate the effects of a home-based exercise program on falls and mobility among people recently discharged from hospital. Methods and Findings This randomised controlled trial (ACTRN12607000563460) was conducted among 340 older people. Intervention group participants (n = 171) were asked to exercise at home for 15–20 minutes up to 6 times weekly for 12 months. The control group (n = 169) received usual care. Primary outcomes were rate of falls (assessed over 12 months using monthly calendars), performance-based mobility (Lower Extremity Summary Performance Score, range 0–3, at baseline and 12 months, assessor unaware of group allocation) and self-reported ease of mobility task performance (range 0–40, assessed with 12 monthly questionaries). Participants had an average age of 81.2 years (SD 8.0) and 70% had fallen in the past year. Complete primary outcome data were obtained for at least 92% of randomised participants. Participants in the intervention group reported more falls than the control group (177 falls versus 123 falls) during the 12-month study period and this difference was statistically significant (incidence rate ratio 1.43, 95% CI 1.07 to 1.93, p = 0.017). At 12-months, performance-based mobility had improved significantly more in the intervention group than in the control group (between-group difference adjusted for baseline performance 0.13, 95% CI 0.04 to 0.21, p = 0.004). Self-reported ease in undertaking mobility tasks over the 12-month period was not significantly different between the groups (0.49, 95% CI −0.91 to 1.90, p = 0.488). Conclusions An individualised home exercise prescription significantly improved performance-based mobility but significantly increased the rate of falls in older people recently discharged from hospital.

An Efficient Public Key Management System: An Application In Vehicular Ad Hoc Networks

The major purpose of Vehicular Ad Hoc Networks (VANETs) is to provide safety-related message access for motorists to react or make a life-critical decision for road safety enhancement. Accessing safety-related information through the use of VANET communications, therefore, must be protected, as motorists may make critical decisions in response to emergency situations in VANETs. If introducing security services into VANETs causes considerable transmission latency or processing delays, this would defeat the purpose of using VANETs to improve road safety. Current research in secure messaging for VANETs appears to focus on employing certificate-based Public Key Cryptosystem (PKC) to support security. The security overhead of such a scheme, however, creates a transmission delay and introduces a time-consuming verification process to VANET communications. This paper proposes an efficient public key management system for VANETs: the Public Key Registry (PKR) system. Not only does this paper demonstrate that the proposed PKR system can maintain security, but it also asserts that it can improve overall performance and scalability at a lower cost, compared to the certificate-based PKC scheme. It is believed that the proposed PKR system will create a new dimension to the key management and verification services for VANETs.
Some Thoughts about Conservative Evaluations of Replications

It is suggested that an unduly conservative research tradition operates in social psychology to heighten the perception of inconsistency in research replications. In large part, this tradition, producing a bias in favor of the null hypothesis, stems from a belief in "the law of small numbers" and a failure to appreciate the probabilistic nature of research results so that each replication or dependent measure is expected to be significant at better than the . 05 level by itself: The legacy of R. A. Fisher's approach to inferential statistics, with its emphasis on avoiding Type I errors and neglect of the possibility of Type II errors, is also considered. It is also noted that social psychological tests of hypothesized relationships are typically low in power. he argument in favor of combining probabilities over the series of replications is supported. It may also be, however; that a good many social psychologists are also greatly risk averse, so that the possibility of a negative outcome (making a mistake) is given very much more weight than positive information (favoring the hypothesis being tested by the research).
Machine understanding of facial expression of pain

An automated system for monitoring facial expressions could increase the reliability, sensitivity, and precision of the research on the relationship between facial signs and experiences of pain, and it could lead to new insights and diagnostic methods. This commentary examines whether the research on facial expression of pain, as reported by Williams, provides a sufficient basis for machine understanding of pain-associated facial expressions.
Reinventing Scheduling for Multicore Systems

High performance on multicore processors requires that schedulers be reinvented. Traditional schedulers focus on keeping execution units busy by assigning each core a thread to run. Schedulers ought to focus, however, on high utilization of on-chip memory, rather than of execution cores, to reduce the impact of expensive DRAM and remote cache accesses. A challenge in achieving good use of on-chip memory is that the memory is split up among the cores in the form of many small caches. This paper argues for a form of scheduling that assigns each object and its operations to a specific core, moving a thread among the cores as it uses different objects.
Poles and Germans: An International Business Relationship

In this article, we aim to identify and explain how Polish managers, in the Polish affiliates of German companies, view their German partners. The theoretical background for this article comes from the field of social anthropology. The empirical data were collected during face-to-face, semi-structured interviews with executives in Poland. The findings presented here are the result of qualitative analysis. We argue that the Polish/German contrast, as perceived by Polish managers, bears a strong resemblance to other core/periphery ethnic relationships in Europe. Parallels are drawn from the British Isles. We argue that the characterizations discussed play an important role in allowing managers to understand their business roles and capabilities within an international business context. A major shortcoming in international business research is the poor understanding of these ingrained attitudes. Our study aims to fill this gap.
Masking Subversion: Neocolonial Embeddedness in Anthropological Accounts of Indigenous Management

Sustainability and sound ecological management of the natural environment, allied to the expanding body of work on managing tacit and explicit knowledge, has led to an increased interest in the contribution which anthropology can make to the practical adaptation of indigenous environmental knowledge and practice to the improvement of organization in western societies. In an exemplary ethnographic study of an indigenous beaver trapper belonging to the Cree Nation, Whiteman and Cooper introduced the concept of ecological embeddedness. Their study could be considered a model that reverses the traditional practice of viewing managers as though they were primitives and applying concepts employed in studying native communities to organizations. They consider indigenous practitioners as managers, identify their management practices, and then reconsider contemporary management practice towards the environment in this light. They argue that to be ecologically embedded as a manager is to identify personally with the land, to adhere to beliefs of ecological respect, reciprocity and caretaking, actively to gather ecological information and to be located physically in the ecosystem. The present article provides a critique of Whiteman and Cooper’s argument and explores the ways in which, at the same time as it is purportedly represented, indigenous thought is masked and thereby subverted. We argue that much of their theorizing - as in so much anthropological accounting - is rooted in neocolonial thought and despite the authors’ claims, a so-called ‘indigenous land ethic’ has limited, if any, relevance to current management theory and practice. This is because such a land ethic is disembedded from the indigenous consciousness of their own economic, social and political history; and similarly for its reception requires a similar disembeddedness in the receiving culture - which then applies a loose analogy or even caricature of indigenous behaviour to its own practices. Such a consciousness remains, therefore, unreflexively embedded in its own neocolonialism. We argue that these problems are not confined to Whiteman and Cooper’s work, but are, to a greater or lesser degree, found in a wide range of anthropological accounts and constitute a problem with which the field is still struggling. To import these features into organizational theorizing without recognizing the deeply problematic nature of contemporary anthropological practice can only produce a reductionist and romanticized picture of native ontologies.
Language Use and PTSD Symptoms: Content Analyses of Allegations of Child Sexual Abuse

The objective of this article is to understand how traumatized children report traumatic narratives. This study aims to explore the mediating effects of posttraumatic stress disorder (PTSD) symptoms on the relationship between child age and narrative characteristics in the allegations of child sexual abuse. Some characteristics of traumatic narratives were analyzed in a group of 58 victims of sexual abuse (M = 10; SD = 3.5 years), including 29 children (50%) with all the symptoms of PTSD. Results were consistent with a model of PTSD symptoms as a mediator of the relationship between age and sensory impressions, emotional nodes, and cognitive distancing.
Music Cultures Opened Up by Music Technologies

Music technologies have opened up various music cultures. For example, any musical instruments such as guitar, piano, and sound synthesizers were originally invented by state-of-the-art music technologies and have had huge influences on music cultures.This keynote talk will demonstrate several practical systems such as VocaListener that can synthesize natural singing voices by analyzing and imitating human singing, VocaWatcher that can generate realistic facial motions of a humanoid robot, Songle (http://songle.jp) that has analyzed more than 840,000 songs on music or video-sharing services and facilitates deeper understanding of music and music-synchronized control of robot dancers, and Songrium (http://songrium.jp) that allows users to explore music while seeing and utilizing various relations among more than 690,000 music video clips on video-sharing services.
Parental Involvement in Juvenile Sex Offender Treatment: Requiring a Role as Informed Supervisor

Sex offenses, particularly those against children, have always been viewed negatively in society. A large portion of these offenses are committed by children against children. Most state legislatures focus on punitive measures when dealing with juvenile sex offenses, yet few place treatment on equal ground. Treatment has been shown to be effective in reducing the rate of recidivism of juvenile sex offenders. Juvenile sex offenders that participate in treatment have shown lower recidivism rates than adult offenders or untreated juvenile sex offenders. This Note advocates that states adopt legislation based on a successful statute in Colorado that creates a sex offender management board consisting of a multidisciplinary treatment team for juvenile sex offenders' treatment while requiring parental involvement in treatment as “informed supervisors” when the team deems it appropriate. Key Points for the Family Court Community: Sex offender treatment on juveniles has been successful in reducing recidivism, as juveniles are more receptive to treatment than adults. Supervision and treatment of juvenile sex offenders would be more effective if parents or guardians are involved in the juvenile's sex offender treatment. States should adopt legislation based on the Colorado model that creates a sex offender management board and multidisciplinary team to supervise the treatment of juvenile sex offenders and requires appropriate parental involvement in the treatment as “informed supervisors”.
The Jolly-Seber-Tag-Loss model with group heterogeneity

Mark-recapture experiments are performed to estimate population parameters such as survival probabilities. Animals are captured, tagged, released, and recaptured at subsequent time periods in order to obtain parameter information. The Jolly-Seber-Tag-Loss (JSTL) model (Cowen & Schwarz, 2006) requires some individuals to be double tagged in order to account for the possibility of animals losing their tags. The Jolly-Seber-Tag-Loss model does not, however, consider the possibility of parameters being different among different groups of individuals, that is, group heterogeneity (for example, males may have higher capture probabilities than females). Our research extends the Jolly-Seber-Tag-Loss model to account for this possibility of group heterogeneity among parameters. We use a Newton-Raphson method to obtain maximum likelihood estimators and R software to create a program that estimates population parameters from tag histories. Our simulation study concludes that when group heterogeneity exists, accounting for this group heterogeneity results in more accurate parameter estimates than the original JSTL model. We present the group heterogeneous JSTL (g-hJSTL) for this purpose.
Multiparametric staining to identify apoptotic human cells.

To analyze relevant features of HeLa and HL60 cells driven into apoptosis by etoposide, we have developed a new "tricolor" assay, based on the simultaneous analysis in the single cell of chromatin condensation, DNA degradation, and cellular poly(ADP-ribose) synthesis. The latter reaction is catalyzed by poly(ADP-ribose)-polymerase (E.C. 2.4.2.30), an enzyme which is activated by the presence of DNA free ends. The protocol consists in the visualization of apoptotic cells by Hoechst staining, TUNEL assay, and immunoreaction with anti-poly(ADP-ribose) antibody. We thus provide the first evidence that endogenous poly(ADP-ribose) production is indeed stimulated in cells undergoing apoptosis after treatment with antitumoral drugs, and that the monitoring of this endogenous enzymatic reaction, combined with morphological and other biochemical parameters, should facilitate the detection of apoptotic cells.
Decolonizing Methodologies: Research and Indigenous Peoples (review)

Indigenous peoples. In addition to basic methods and methodologies courses, this book should be required reading on any syllabi geared towards the formation of students’ thinking about scientific research theory and practice more generally. Case examples cited in support of Smith’s critique of conventional academic research range from early European taxonomical expeditions of exploration, to the contemporary patenting of Indigenous genetic material. These are offset in the second part of the book where her examples grounded in local Maori initiatives illustrate Indigenous research approaches. Linda Tuhiwai Smith has provided a concise, well-written, accessible framework for understanding the historical development of research in relation to imperial and colonial projects, as well as how these still persist and permeate even the best-intentioned research in Indigenous communities today. In brief, this is an outstanding and pivotal book that is crucial to everyone concerned with understanding the sociohistorical forces that have driven research practices and the consequential responsibilities researchers need to assess, acknowledge, and enact.
Automatic Code Generation for SIMD DSP Architectures: An Algebraic Approach

Driven by the ever increasing algorithm complexity on the field of mobile communications systems, SIMD DSP architectures have emerged as an approach that offers the necessary processing power at reasonable levels of die size and power consumption. However, this kind of DSP architectures imposes new challenges for programmers, since algorithms have to be designed to exploit the available parallelism on the processor. Taking as a starting point an algebraic framework that captures the SIMD computational model, we report in this paper about our efforts to design and automatically generate object code for our family of DSP architectures independent of the available SIMD parallelism. We show how these algebraic structures can be used as a high level programming language that offers a unified approach to design and describe algorithms using SIMD parallelism. Moreover, we show how these algebraic structures offer concise rules for the automatic code generation.
Treatment of Nevus lipomatosus cutaneous superficialis with CO2 laser

Nevus lipomatosus cutaneous superficialis (NLCS) is an uncommon lesion characterized by ectopic adipose tissue in the dermis and can be generalized or localized. It presents as a soft skin colored to yellowish papules or cerebriform plaques occurring usually on the buttock or thigh in a segment distribution. We report a case of NLCS in 38‐year‐old female, which was treated using the ultrapulse mode CO2 Laser. We describe the scientific logic and clinical results of using the ultrapulse mode in relation to the pathology of NLCS.
