Uncovering the Riffled Independence Structure of Rankings

Representing distributions over permutations can be a daunting task due to the fact that the number of permutations of $n$ objects scales factorially in $n$. One recent way that has been used to reduce storage complexity has been to exploit probabilistic independence, but as we argue, full independence assumptions impose strong sparsity constraints on distributions and are unsuitable for modeling rankings. We identify a novel class of independence structures, called \emph{riffled independence}, encompassing a more expressive family of distributions while retaining many of the properties necessary for performing efficient inference and reducing sample complexity. In riffled independence, one draws two permutations independently, then performs the \emph{riffle shuffle}, common in card games, to combine the two permutations to form a single permutation. Within the context of ranking, riffled independence corresponds to ranking disjoint sets of objects independently, then interleaving those rankings. In this paper, we provide a formal introduction to riffled independence and present algorithms for using riffled independence within Fourier-theoretic frameworks which have been explored by a number of recent papers. Additionally, we propose an automated method for discovering sets of items which are riffle independent from a training set of rankings. We show that our clustering-like algorithms can be used to discover meaningful latent coalitions from real preference ranking datasets and to learn the structure of hierarchically decomposable models based on riffled independence.
Examining the role of teacher presence and scaffolding in preschoolers’ peer interactions

ABSTRACT The current study aimed to examine the associations between teacher presence and social scaffolding and preschool children’s peer interactions. Using a time sampling method, peer interactions of 22 four- and five-year-old preschoolers (12 girls; Mage = 52.95 months) and teacher behavior were observed on two different days during various classroom activities in seven public preschool classrooms. Eco-behavioral analyses revealed that (a) teacher presence was negatively associated with positive peer interactions; (b) teacher absence was positively associated with negative peer interactions; (c) positive change of peer interactions was more likely to occur when the teacher was present; (d) children showed more positive peer interactions during child-directed activities than during adult-directed activities or daily routines and transitions; and (e) teacher’s social scaffolding was positively associated with children’s positive peer interactions although it occurred only for 3.61% of the intervals during which the teacher was in close proximity to children. In addition, although the likelihood for children’s positive interaction was over 2 times higher in child-directed activities in comparison to adult-directed activities, teacher presence still seems very important for inhibiting negative peer interactions.
Pengaruh Self Efficacy terhadap Subjective Well-being pada Guru SLB di Kota Padang

The Influence of Self Efficacy towards Subjective Well-being on Special Education (SLB)’s Teacher in Padang Karlina Agustin ABSTRACT Problems subjective well-being on SLB’s teachers are the complexity of the task into a SLB’s teacher and the lack of supporting facilities for teaching and learning activities. One of the factors that affect subjective well-being is called self efficacy that is given contribution of satisfaction and well-being of individuals. This study aimed to determine the influence of self efficacy towards subjective well-being on SLB’s teacher in Padang. The method used was Quantitative Research Methods. Measurement used the scale of life satisfaction called Satisfaction With Life Scale (SWLS) with reliability 0.919, Positive And Negative Affective Scale (PANAS) with reliability 0.935 for subjective well-being, and the self efficacy scale were made by researcher based on theory of Bandura which divided into three dimension were level, generality, and strength with the reliability of 0,954. Samples included 97 teachers from Special Education (SLB) in Padang,which by used the purposive sampling. Analytical technique that used by a simple linear regression. The results showed that the value of significance (p) was 0.010 < 0.05. Based on these results the alternative hypothesis (Ha) research was accepted. The significant value proved that self efficacy gave signification of effection towards subjective well-being on SLB’s teacher in Padang. This means, high and low self efficacy can affect a person's subjective well-being. Meanwhile, the value of R2 was 0.068 indicated the self efficacy contributed to influence of subjective well-being as much as 6.8%. Keywords: self-efficacy, subjective well-being, SLB’s teachers
THE INFLUENCE OF AUTONOMIC SIGNALS ON PERCEPTION OF EMOTIONS IN EMBODIED AGENTS

Specific patterns of autonomic activity have been reported when people experience emotions. Typical autonomic signals that change with emotion are wrinkles, blushing, sweating, tearing and respiration. This article explores whether these signals can also influence the perception of emotion in embodied agents. The article first reviews the literature on specific autonomic signal patterns associated with certain affective states. Next, it proceeds to describe a real
Quantum Monte Carlo calculations of A=8 nuclei

We report quantum Monte Carlo calculations of ground and low-lying excited states for A=8 nuclei using a realistic Hamiltonian containing the Argonne v{sub 18} two-nucleon and Urbana IX three-nucleon potentials. The calculations begin with correlated eight-body wave functions that have a filled {alpha}-like core and four p-shell nucleons LS coupled to the appropriate (J{sup {pi}};T) quantum numbers for the state of interest. After optimization, these variational wave functions are used as input to a Green's function Monte Carlo calculation made with a new constrained path algorithm. We find that the Hamiltonian produces a {sup 8}Be ground state that is within 2 MeV of the experimental resonance, but the other eight-body energies are progressively worse as the neutron-proton asymmetry increases. The {sup 8}Li ground state is stable against breakup into subclusters, but the {sup 8}He ground state is not. The excited state spectra are in fair agreement with experiment, with both the single-particle behavior of {sup 8}He and {sup 8}Li and the collective rotational behavior of {sup 8}Be being reproduced. We also examine energy differences in the T=1,2 isomultiplets and isospin-mixing matrix elements in the excited states of {sup 8}Be. Finally, we present densities, momentum distributions, and studies of the intrinsicmore » shapes of these nuclei, with {sup 8}Be exhibiting a definite 2{alpha} cluster structure.

Short communication Baboons communicate with their right hand

Humans are mainly right-handed for many actions including gestures. This bias is strongly linked to a left cerebral hemispheric dominance for language functions. Whether similar lateralized systems for communicative behaviors are present in other animals is unclear. Here we report the first evidence of strong population-level right-handedness in 60 captive baboons for a species-specific communicative manual gesture. Our findings support the view that lateralization for language may have evolved from a gestural system of communication controlled by the left hemisphere. © 2006 Elsevier B.V. All rights reserved.
Influence of Different Supplements on the Commercial Cultivation of Milky White Mushroom

Calocybe indica, known as milky white mushroom, grows and cultivated in the sub-tropical and temperate zones of South Asia. We investigated the most suitable supplements and their levels for the commercial cultivation of milky white mushroom. Rice bran, maize powder, and wheat bran with their different levels (10, 20, 30, 40, and 50%) were used as supplements to evaluate the yield and yield contributing characteristics of C. indica. Primordia initiation was observed between 13.5 and 19.3 days. The results indicated that the 30% maize powder supplement was effective for producing viable fruiting bodies. The maximum diameters of the pileus and stalk were observed with 30% maize powder. The highest biological and economic yield and biological efficiency were also obtained with 30% maize powder as a supplement. The results indicate that increasing the supplement level resulted in less biological efficiency, and that 30% maize powder was the best supplement level for rice straw substrate to cultivate milky white mushrooms.

The Effects of Task Complexity on Heritage and L2 Spanish Development

Abstract:Manipulating cognitive demands on second language (L2) tasks, along with the provision of recasts and its effects on L2 development, has motivated recent inquiry within task-based research. However, empirical evidence remains inconclusive as to the impact of task complexity, and it is unknown how it may affect heritage language (HL) development. To address this issue, this study tested 81 adult HL and L2 learners of Spanish. Participants in the experimental conditions completed either a simple or a complex version of a monologic computerized task that delivered written recasts as corrective feedback but differed according to intentional reasoning demands. Participants completed three oral and written assessment tasks to measure development of the Spanish subjunctive in adjectival clauses. Results revealed that the simple group demonstrated greater gains, especially in written production. L2 learners and the HL simple group benefitted more from task-based instruction in comparison to the HL complex group. Findings have implications for the role of prior language experience and task outcomes. Résumé:La manipulation des exigences cognitives des tâches en langue seconde (L2) de même que la reformulation et son incidence sur le perfectionnement en langue seconde ont récemment incité les chercheurs à s'interroger sur les méthodes axées sur les tâches. Les données empiriques ne permettent cependant pas de tirer des conclusions quant aux conséquences de la complexité de la tâche, et l'on ignore en quoi cette variable peut influer sur le perfectionnement de la langue patrimoniale (HL). L'auteur, qui se penche sur cette question, teste le perfectionnement du langage adulte chez 81 adultes apprenants de l'espagnol, langue patrimoniale et langue seconde. Selon le groupe expérimental, les participants sont appelésà s'acquitter d'une tâche informatisée de monologue, soit en version simple soit en version complexe, dans laquelle sont proposées des reformulations écrites à titre de rétroaction corrective, mais qui diffèrent au chapitre des exigences de raisonnement intentionnel. Les participants effectuent trois tâches d'évaluation orale et écrite visant à mesurer leur maîtrise du subjonctif espagnol dans les propositions adjectivales. Les résultats révèlent que les membres du groupe auquel est assignée la tâche simple affichent des gains supérieurs, particulièrement en production écrite. Les apprenants de la langue seconde et les apprenants de la langue patrimoniale auxquels est assignée la tâche simple bénéficient davantage de l'exercice axé sur les tâches que les apprenants de la langue patrimoniale auxquels est assignée la tâche complexe. Ces observations ont des répercussions sur le rôle des connaissances linguistiques préalables et les résultats de la tâche.
Neurological Soft Signs, Cognition in Childhood, Attention Deficit Hyperactivity Disorder and Lifetime Major Depressive Disorder

Background: Neurological soft signs (NSS), subtle but abnormal motor and sensory signs and involuntary movements, have been implicated as risk factors for a number of psychiatric and neurodevelopmental disorders. Prior studies were based on small clinical samples, did not control for important confounding factors or examine domain or age specificity. Here we investigate the associations between NSS and multiple domains of cognitive functioning, Attention Deficit Hyperactivity Disorder (ADHD) and its subtypes and finally with lifetime diagnosis of major depressive disorder (MDD) and its age of onset in a large, population-based cohort, while adjusting for important confounding factors. Methods: We analyzed data from the Collaborative Perinatal Project (CPP), that followed the offspring of a pregnancy cohort till the age of seven and its follow up project, the New England Family Studies (NEFS) that followed the adult offspring of the Providence and Boston sites of the CPP. We adjusted for a wide array of confounding factors, including demographic variables as well as risk factors for brain injury and aberrant neurodevelopment. Results: NSS were associated with poor cognitive performance across all domains with no specificity. Each additional soft sign was associated with approximately 4 units drop in any cognitive score. NSS were associated with increased odds of all subtypes of ADHD. Each additional soft sign was associated with 70% increase in the odds of ADHD diagnosis. However, NSS was not associated with a higher risk of major depressive disorder in childhood compared to adolescence or adulthood. Conclusions: There is an association between NSS and poor cognitive performance and ADHD that is not attributable to established risk factors for brain injury and aberrant neurodevelopment. Further research should seek the mechanisms for these associations, and finally evaluate the effectiveness of interventions targeting NSS in the assessment and treatment of these childhood conditions.
Effect of alexithymia on the relationship between affective arousal and additional heart rate

Emotions can be categorized into two dimensions: valence and arousal. Valence varies from negative to positive, whereas arousal varies from low to high. Affective arousal indicates the intensity of emotions and varies over time between and within individuals, which can be measured by self-report, behavior or physiology. Individuals differ markedly in the variability of their reports on different emotional experiences. An example is the personality trait alexithymia, which is known as reduced capabilities in experiencing, recognizing, imagining and describing of own emotions and those of others. An interesting but not yet well tested physiological measure of arousal is additional heart rate. Additional heart rate is the weighted heart rate difference per minute divided by the mean vector of acceleration, in order to rule out the effect of physical activity on heart rate. Affective arousal activates the autonomic nervous system which increases additional heart rate. The current study was an experience sampling study on within-subject level, based on an intensive longitudinal method in daily life. During seven days, thirteen participants wore an E4 wristband which measured physiology and filled out a questionnaire about the intensity of experienced emotions every two hours. First, it was hypothesized that additional heart rate and self-reported arousal correlate positively. Second, it was hypothesized that alexithymia negatively moderates the relationship between additional heart rate and self-reported arousal.
Isotopic compositions of lipid biomarker compounds in estuarine plants and surface sediments

We examined the isotopic compositions of fatty acids, sterols, and hydrocarbons isolated from three coastal macrophytes (Zostera marina, Spartina alterniflora, and Juncus roemerianus) in order to investigate the relative contribution of these vascular plants as sources of organic matter in coastal sediments such as Cape Lookout Bight, North Carolina. On average, lipid biomarker compounds extracted from the plants were depleted in 13C by 3–5‰ relative to δ13C total organic carbon (TOC). However, individual compounds within each lipid class varied by up to 5.6‰. Trends in the isotopic compositions of lipids were consistent with δ13CTOC; compounds obtained from Z. marina were the most enriched in 13C and those from J. roemerianus were the most depleted. The range in isotopic abundances and molecular compositions of the sediments was greater than that obtained from the plants, indicating that additional, presently unidentified sources of organic matter contribute to the Cape Lookout Bight sediments. Similarity between the signatures for suspended particulate matter and the sediments indicates that much of the sedimentary organic matter is derived from algal and bacterial sources. Bacterial sources of organic matter are likely greater during summer/early fall, and incorporation of 13C‐enriched bacterial biomass may contribute to observed seasonal shifts in δ13CTOC in the surficial sediments.
Evolutionary Optimization of Dynamic Multiobjective Functions

Multi-objective as well as dynamic characteristics appear in many real-world problems. In order to use multi-objective evolutionary optimization algorithms (MOEA) efficiently, a systematic analysis of the algorithms’ behavior in dynamic environments by means of dynamic test functions is necessary. These functions can be classified into problems with changing Pareto sets and/or Pareto fronts with different dynamic criteria. Thus, a test suite with existing benchmark functions having dynamic behavior and new designed dynamic test functions for yet uncovered cases is proposed. Convergence and solution distribution features of modern MOEA, namely NSGA-II, SPEA2, and MSOPS using different variation operators (Simulated Binary Crossover with Polynomial Mutation and Differential Evolution) will be analyzed. For this reason, a new path integral metric is introduced. Especially the transfer of singleobjective results and the ability of the algorithms to use historically evolved population properties will be discussed.

The Open University ’ s repository of research publications and other research outputs Adoption Rationales of New Management Practices

This study considers that multiple and diverse rationales, including rational, emotional and socially conditioned responses can influence the adoption of management practices. The study includes four case studies in order to subject the adoption rationales that Sturdy (2004) posits to empirical inquiry and to explore the impacts of these differing rationales on characteristics of the subsequent adoption. The findings show that five of the six rationales Sturdy proposes are empirically identifiable. The findings also suggest that, subject to the exploratory nature of the study, earlier adoption of management practices is associated with political and psychodynamic rationales, consistent with notions of being seen to adopt new ways of working. The findings also suggest that the political and dramaturgical rationales are associated with more rapid adoption due to influential individuals or groups acting as champions. Whilst Sturdy proposes his rationales as a simple list, the findings of this study suggest a more complex relationship between the rationales. The study contributes to the growing body of literature that addresses the important topic of management practices, particularly those that provide an expository consideration.
Mobility as an Aspect : The AspectM Framework

Software engineers of multi-agent systems (MASs) are faced with the design and implementation of the mobility concern in addition to the agents’ basic functionalities and other agent-related concerns. As the agents’ complexity increases, the mobility concern cannot be modularized based only on object-oriented abstractions. The mobility concern tends to spread across several system classes and methods, which in turn leads to the production of MASs that are difficult to maintain and reuse. MAS developers, however, have mostly relied on object-oriented frameworks and on object-oriented programming languages, such as Java. This paper presents an aspect-oriented framework, called the AspectM framework, that supports improved modularization of the mobility concern and a flexible integration with multiple mobility platforms. The use of our framework minimizes code replication, and increases the reusability and maintainability of the mobility concern and other agent concerns.
