Connecting Students Internationally to Explore Postconflict Peacebuilding: An American–Canadian Collaboration

This paper presents the design and assesses the results of an international collaborative course of American and Canadian undergraduates on the topic of postconflict peacebuilding. Using online discussions, a web-based role-play simulation, and videoconferencing this collaborative course sought to enhance student engagement with the material by exposing them to views from different countries and encouraging broader thinking about the complex set of activities and challenges involved in peacebuilding. The challenges and benefits of such collaboration are discussed.
{μ-1,5-Bis[(E)-1-(2-pyridyl)ethylidene]carbonohydrazidato(1−)}bis[chloridomethanolcopper(II)] perchlorate

The title dinuclear copper complex, [Cu2(C15H15N6O)Cl2(CH3OH)2]ClO4, was prepared by the reaction of copper(II) chloride with bis[1-(2-pyridyl)ethylidene]carbonohydrazide in the presence of sodium perchlorate in a methanol solution. It features a mono-deprotonated bis-tridentate ligand, which coordinates to two independent CuII ions, one of which is coordinated by pyridyl N, hydrazyl N and carbonyl O atoms. The second CuII ion is coordinated by the pyridyl N and two hydrazyl N atoms from different hydrazyl groups. The coordination environments of both CuII ions are completed by a chloride ion and a methanol molecule. The dihedral angle between the pyridyl groups is 27.46 (10)°. The crystal packing is stabilized by O—H⋯O(perchlorate), O—H⋯Cl and N—H⋯Cl hydrogen bonding.
Optical flow field segmentation in an omnidirectional camera image based on known camera motion

We consider the problem of optical flow analysis in an omnidirectional camera image, in order to segment out dynamic objects from ego-motion caused optical flow. The aim is to use the camera on a mobile robot, thus making it reasonable to assume knowledge of the camera movement in the horizontal plane. Estimation of the optical flow is performed in the omnidirectional image. By knowing the ego-motion, it is possible to calculate the resulting optical flow field with the necessary assumption of planarity of the surrounding scene (the mobile robot is in an open, flat space). However, comparing the calculated and estimated flow field, with the latter assumption by comparing the flow vectors or winding, did not result in satisfactory estimates. Therefore, we propose to geometrically map the optical flow vectors on a sphere, centered at the center of the central panoramic camera projection, since we observed the space angle to be invariant to the errors of the planar space assumption. In the experiments we show that the proposed approach is more robust than comparing the flows in the image plane. In addition, properties of the observed angle for the inverse problem of determining camera ego-motion are considered.
An exploratory study of project success with tools, software and methods

Purpose – The purpose of this paper is to examine the relationships between project delivery success factors, project management tools, software, and methods.Design/methodology/approach – A statistical analysis was undertaken using data from a survey from a purposive sample of 150 participants across three countries (Australia, Canada and the UK). The findings were used to consider the relationships between project success factors, project management tools, software, and methods.Findings – The findings reveal certain insights in the use of tools and methodologies. Of all the variables measured, the number of project management tools used and the number of risk tools used showed the highest direct correlation. It was therefore surmised that the use of tools from one of these categories is often coincident with the use of tools from the other category. Also, the use of project management tools exhibited less variability as compared to use of information communication technology support tools and risk manage.
Evolutionary Synthesis Of Control Law For Higher Periodic Orbits Of Chaotic Logistic Equation

This research deals with a synthesis of control law for selected discrete chaotic system by means of analytic programming. The novelty of the approach is that a tool for symbolic regression – analytic programming is used for the purpose of stabilization of higher periodic orbits – oscillations between several values of chaotic system. The paper consists of the descriptions of analytic programming as well as chaotic system and used blackbox type cost function. For experimentation, Self-Organizing Migrating Algorithm (SOMA) with analytic programming and Differential evolution (DE) as second algorithm for meta-evolution were used.
Discovering expressive realtime parameters: The performing laptop artist as effects designer

Over the last several years, we (all "laptop artists" of this sort) have been active as performers, composers, software/DSP developers and hardware instrument builders. In particular, we have been seeking more compelling physical connections between body and digital sound, creating personalized hardware/sensor interfaces [1] [2], connecting them to custom signal-processing algorithms, and generating electronic sound through various kinds of speaker arrangements (both outside-in surround configurations and inside-out spherical arrangements) [3] [4].
Constructing Services with Interposable Virtual Hardware

Virtual machine monitors (VMMs) have enjoyed a resurgence in popularity, since VMMs can help to solve difficult systems problems like migration, fault tolerance, code sandboxing, intrusion detection, and debugging. Recently, several researchers have proposed novel applications of virtual machine technology, such as Internet Suspend/Resume [25, 31] and transparent OS-level rollback and replay [13]. Unfortunately, current VMMs do not export enough functionality to budding developers of such applications, forcing them either to reverse engineer pieces of a black-box VMM, or to reimplement significant portions of a VMM. In this paper, we present the design, implementation, and evaluation of µDenali, an extensible and programmable virtual machine monitor that has the ability to run modern operating systems. µDenali allows programmers to extend the virtual architecture exposed by the VMM to a virtual machine, in effect giving systems programmers the ability to dynamically assemble a virtual machine out of either default or custom-built virtual hardware elements. µDenali allows programmers to interpose on and modify events at the level of the virtual architecture, enabling them to easily perform tasks such as manipulating disk and network events, or capturing and migrating virtual machine state. In addition to describing and evaluating our extensible virtual machine monitor, we present an application-level API that simplifies writing extensions, and we discuss applications of virtual machines that we have built using this API.
Constructions of Students as Clients or Partners in Knowledge Creation

This study explored notions of ‘the student’ within the South African higher education context. Qualitative data from interviews with twenty-three executive and senior Student Affairs staff and practitioners were collected from three higher education institution in South Africa. The data were thematically analysed. The findings suggest that notions about students as ‘disadvantaged’ and ‘needing support’ as reflected in the South African policy documents is not congruent with the discourses in current Student Affairs in South Africa. Findings suggest that deficit discourses have been replaced by strengths based paradigms which construct the student in heterogeneous individualistic terms. Consumerist frameworks constructing the student as client have also emerged. The conceptual framework within which Student Affairs is embedded needs to reflect the changed discourse in Student Affairs practice in South Africa.
An Approach to Reference Architecture Design for Different Domains of Embedded Systems

The content of this paper addresses the issues regarding the reference architecture design for different domains in the context of a system of systems that is specific to today’s embedded systems. The reference architecture contains core services of the domains included in abstract features package. The appropriate architectural style is provided by a knowledge base through service taxonomy. Services, commonality, variability management and rules for product derivation and configuration are the main issues considered in the architectural design process. Our contribution is the integrated vision based on our experiences and studies of the recent publications.
Suicide Attempts among Norwegian Gay, Lesbian and Bisexual Youths

The aim of the study was to identify the specific factors that affect the risk of attempted suicide in Norwegian gay, lesbian and bisexual (GLB) youths beyond the effect of general risk factors presumed to be of importance irrespective of sexual orientation. The national non-probability sample included 407 GLB youths aged between 16 and 25 years of age, among whom 26 per cent of both genders reported a previous suicide attempt. General risk factors for attempted suicide among GLB youths were: lack of parental contact, internalizing problems (depression/anxiety), low self-esteem, regular smoking and victimization. The following risk factors specific for GLB youths increased the risk of attempted suicide even when controlling for general risk factors: currently being in a steady heterosexual relationship, early heterosexual debut (<16), young age of coming out (<15), infrequent contact with heterosexual friends and openness to all heterosexual friends. For practitioners engaged in social work among young people in general or GLB youths in particular, these results show that while coming out is a vital aspect of sexual identity formation that enhances psychological well-being and should be celebrated, in another sense it is a serious stressor with potentially negative consequences unless a strong social support network is there to be relied upon.
Bmc Plant Biology

A clarified position for solanum lycopersicum var. cerasiforme in the evolutionary history of tomatoes (solanaceae) Abstract Background: The natural phenotypic variability present in the germplasm of cultivated plants can be linked to molecular polymorphisms using association genetics. However it is necessary to consider the genetic structure of the germplasm used to avoid false association. The knowledge of genetic structure of plant populations can help in inferring plant evolutionary history. In this context, we genotyped 360 wild, feral and cultivated accessions with 20 simple sequence repeat markers and investigated the extent and structure of the genetic variation. The study focused on the red fruited tomato clade involved in the domestication of tomato and confirmed the admixture status of cherry tomatoes (Solanum lycopersicum var. cerasiforme). We used a nested sample strategy to setup core collection maximizing the genetic diversity with a minimum of individuals.
A SAS Macro for Calculating New Methods of Error Control in Multiple Hypothesis Testing

The testing of multiple null hypotheses in a single study is a common occurrence in applied research. The problem of Type I error inflation or probability pyramiding in such contexts has been well-known for many years. General procedures for the control of Type I error rates in multiple testing are the Bonferroni procedure and its’ more recent modifications. These procedures partition a desired level of Familywise error across the set of hypotheses being tested. Recent work on multiple testing by Benjamini and Hochberg (1993, 1995, 2000) has focused on controlling the False Discovery Rate (FDR) rather than rates of Type I error. The adaptive (BH-A) and nonadaptive (BH) procedures for controlling the FDR in a set of tests promise increases in statistical power relative to other procedures. This paper presents a SAS macro that calculates probabilities under five decision rules that may be used in multiple testing (per hypothesis rule, Bonferroni, Hochberg, BH, BH-A) The macro evaluates a set of probabilities that are supplied as an input. Macro outputs include the results of the five decision rules applied to the set of probabilities. The paper provides a demonstration of the SAS/IML code and examples of the application of the code in simulation studies.
Shifts in Public Affairs Reporting on the Network Evening News: A Move Toward the Sensational

This study examined the shift away from traditional public affairs reporting toward sensationalism on the network evening news between 1968 and 1996. Using methods developed by Adams (1978) and extended by Slattery and Hakanen (1994), this study found an increase in the proportion of sensationalism in network newscasts over time. The study found that 1996 news content categorized as non-election public affairs coverage contained significantly higher levels of embedded sensationalism than similar content in 1968.
Estimation of Human Workload from the Auditory Steady-State Response Recorded via a Wearable Electroencephalography System during Walking

Workload in the human brain can be a useful marker of internal brain state. However, due to technical limitations, previous workload studies have been unable to record brain activity via conventional electroencephalography (EEG) and magnetoencephalography (MEG) devices in mobile participants. In this study, we used a wearable EEG system to estimate workload while participants walked in a naturalistic environment. Specifically, we used the auditory steady-state response (ASSR) which is an oscillatory brain activity evoked by repetitive auditory stimuli, as an estimation index of workload. Participants performed three types of N-back tasks, which were expected to command different workloads, while walking at a constant speed. We used a binaural 500 Hz pure tone with amplitude modulation at 40 Hz to evoke the ASSR. We found that the phase-locking index (PLI) of ASSR activity was significantly correlated with the degree of task difficulty, even for EEG data from few electrodes. Thus, ASSR appears to be an effective indicator of workload during walking in an ecologically valid environment.
Reconfigurable Low Complexity Fir Filters for Software Radio Receivers

The most computationally demanding block of a software defined radio (SDR) receiver is the channelizer which operates at the highest sampling rate. Reconfigurability and low complexity are the two key requirements of the SDR channelizers. Two new reconfigurable architectures of low complexity finite impulse response (FIR) filters for channelizers are proposed in this paper. Our methods are based on the binary common subexpression elimination (BCSE) algorithm. The proposed architectures are capable of operating at a high speed clock frequency of 109.7 MHz based on Xilinx's Virtex II 2v2000ff896-6 FPGA for a 12-bit FIR filter coefficient. Design examples show that our method offers an average reduction of 23% in the number of addition operations compared to the conventional FIR filter implementations
Parental Power and Adolescents' Parental Identification: A Reexamination.

This paper reexamines the relationship between adolescent perceptions Qf paternal and maternal power and adolescents' identification with parents. The initial research tested a social power theory of parental identification, in contrast to sex-role theories of identification, which argued that the more parental power each parent is perceived to have, the higher the degree of adolescent identification with that parent. Regression analyses supported the theory with differing degrees of strength across the power dimensions. This study is largely a replication of the earlier study, with several additional strengths, including: (1) a larger sample size (N = 296); (2) younger, high school level adolescent respondents; (3) a different region of the country; (4) a rural, rather than urban, area of residence; and (5) internal reconstruction of the questionnaire. Again, regression analysis is utilized and the major hypothesis is generally supported. However, the relationships are evidenced as weaker, in certain respects, in the replication than in the original research. These findings are systematically discussed.
Utilize Item Correlation to Improve Aggregate Diversity for Recommender Systems

Nowadays, more and more researchers have noticed that recommenders performing well with respect to accuracy do not necessarily mean that they produce the most effective recommendations in practice. Aspects such as aggregate diversity were identified as additional factors that can positively or negatively affect the quality of recommendations. The major challenge for improving aggregate diversity for a recommender system lies in the data imparity problem for popular items and niche items. Recommender systems are more inclined to recommend popular items that maintain sufficient user feedback while ignoring niche items that have been rated by a small portion of users. To address this problem, we associate popular items and niche item via item features. The correlation between items are calculated by meta-path similarity measurement in a heterogeneous information network. Finally, we propose an Item Correlation based Probabilistic Matrix Factorization method, incorporating multiple item features and collaborative data. Empirical studies based on a real world data set demonstrate the effectiveness of this method and show that it outperforms state-of-the-art methods for improving aggregate diversity.
Repeatability of the Evaluation of Perception of Dyspnea in Normal Subjects Assessed Through Inspiratory Resistive Loads

Purpose: Study the repeatability of the evaluation of the perception of dyspnea using an inspiratory resistive loading system in healthy subjects. Methods: We designed a cross sectional study conducted in individuals aged 18 years and older. Perception of dyspnea was assessed using an inspiratory resistive load system. Dyspnea was assessed during ventilation at rest and at increasing resistive loads (0.6, 6.7, 15, 25, 46.7, 67, 78 and returning to 0.6 cm H2O/L/s). After breathing in at each level of resistive load for two minutes, the subject rated the dyspnea using the Borg scale. Subjects were tested twice (intervals from 2 to 7 days). Results: Testing included 16 Caucasian individuals (8 male and 8 female, mean age: 36 years). The median scores for dyspnea rating in the first test were 0 at resting ventilation and 0, 2, 3, 4, 5, 7, 7 and 1 point, respectively, with increasing loads. The median scores in the second test were 0 at resting and 0, 0, 2, 2, 3, 4, 4 and 0.5 points, respectively. The intra-class correlation coefficient was 0.57, 0.80, 0.74, 0.80, 0.83, 0.86, 0.91, and 0.92 for each resistive load, respectively. In a generalized linear model analysis, there was a statistically significant difference between the levels of resistive loads (p<0.001) and between tests (p=0.003). Dyspnea scores were significantly lower in the second test. Conclusion: The agreement between the two tests of the perception of dyspnea was only moderate and dyspnea scores were lower in the second test. These findings suggest a learning effect or an effect that could be at least partly attributed to desensitization of dyspnea sensation in the brain.
High Frequency of Putative Ovarian Cancer Stem Cells With CD44/CK19 Coexpression Is Associated With Decreased Progression-Free Intervals In Patients With Recurrent Epithelial Ovarian Cancer

Objective: Epithelial ovarian cancer (EOC) cells with CD44 and CK19 coexpression may represent a subset of ovarian cancer stem cells (OCSCs). This study was conducted to evaluate the correlation of the frequency of putative OCSCs (CD44 + CK19 + OCSCs) with the clinicopathologic features and the prognostic value in patients with recurrent advanced stage EOC. Methods: A retrospective study was carried out on 33 patients with EOC and a uniformly treated tissue microarray was constructed. A multiplexed, immunofluorescence-based method of automated in situ quantitative measurement of protein analysis was used for evaluation of the frequency or density of CD44 + CK19 + OCSCs in EOC. Results: The mean follow-up time was 42.8 ± 27.1 months. High frequency of EOC cells with CD44+ or CD44+/CK19+ was associated with chemoresistance (P = .033 and P = .02, respectively). Using K-M analysis with log-rank test, a high frequency of putative OCSCs was associated with short disease-free interval (7.9 months vs 20.9 months, P = .019). In univariable analysis, the frequency of OCSCs, International Federation of Gynecology and Obstetrics stage and residual tumor volume were significant predictor variables and were entered into multivariable analysis (P = .019, .037, and .005, respectively). Although no independent significant predictor was found, the frequency of putative OCSCs was the most promising predictor variable compared with the other 2 variables (hazard ratio = 2.344, P = .052). Conclusion: Our findings suggest that high frequency of OCSCs (CD44+ and CK19+) in epithelial ovarian tumors correlates with short progression-free intervals.
Unresolved Issues Regarding Homework Assignments in Cognitive and Behavioural Therapies: An Expert Panel Discussion at AACBT

Abstract This article presents a panel discussion on the integration of homework assignments into cognitive behaviour therapy sessions. The panel comprised experts in research and practice who had been invited as keynote presenters for the 32nd National Conference for the Australian Association of Cognitive and Behaviour Therapy. Experts responded to questions about the definition of homework, the mechanism by which homework produces its effects, and the relative importance of homework adherence for effective therapy. Interwoven through the discussion was an emphasis on a collaborative approach to homework, as well as specific recommendations for the integration of homework into sessions. Selected case illustrations were also discussed.
On placing skips optimally in expectation

We study the problem of optimal skip placement in an inverted list. Assuming the query distribution to be known in advance, we formally prove that an optimal skip placement can be computed quite efficiently. Our best algorithm runs in time O (n log n), n being the length of the list. The placement is optimal in the sense that it minimizes the expected time to process a query. Our theoretical results are matched by experiments with a real corpus, showing that substantial savings can be obtained with respect to the traditional skip placement strategy, that of placing consecutive skips, each spanning √n many locations.
Augmenting the Medical Subject Headings vocabulary with semantically rich variants to improve disease mention normalisation

We extended our existing methods for entity normalisation as part of our contribution to the Disease Named Entity Recognition and Normalisation subtask of the Chemical-Disease Relation (CDR) track of BioCreative V. Our newly proposed approach is based on the incorporation of semantics in two ways: (1) by adding corpus-derived semantic variants to the Medical Subject Headings (MeSH) vocabulary, and (2) through automatic translation of medical root words and affixes to potential variants. Results of the official evaluation of our methods show that the combination of both means for semantic enrichment gives us optimal performance on the disease name normalisation task, obtaining an F-score of 85.56%, with precision of 89.51% and recall of 81.94%. We have made our methods available in the form of a BioC-compliant Web service.
