Determining the Influence of Reddit Posts on Wikipedia Pageviews

The activity of passive content consumers on social media sites is typically difficult to measure. This paper explores the activity of a subset of such consumers by looking at the influence on Wikipedia pageviews of one large Reddit community which frequently links to Wikipedia articles. The subreddit used in this analysis, /r/todayilearned (TIL), features a large number of posts on an eclectic set of topics, but excludes current events, which helps rule out the primary threat to being able to make causal statements. Wikipedia's public hourly pageview data provides a unique opportunity to study the influence of a Reddit post on a Wikipedia page at different time horizons. We here present analyses using posts from 2012 in TIL, showing that the week in which a post references a specific Wikipedia article is associated with a substantial increase in pageviews relative to prior and successive weeks. We then apply functional PCA to the dataset in order to characterize pageview dynamics. We also provide a qualitative analysis of the subset of Wikipedia topics posted to Reddit.
Adverse pregnancy outcomes with assisted reproductive technology in non-obese women with polycystic ovary syndrome: a case-control study

Objective To investigate adverse pregnancy outcomes in non-obese women with polycystic ovary syndrome (PCOS) compared with obese-PCOS and control groups. Methods Women with PCOS who underwent assisted reproductive technology (ART) from August, 2003 to December, 2007, were considered. A total of 336 women with PCOS were included in the study group and 1,003 infertile women who had tubal factor as an indication for ART were collected as controls. They were divided into four groups: a non-obese PCOS group, obese-PCOS group, non-obese tubal factor group, and obese tubal factor group, with obesity defined by a body mass index over 25 kg/m2, and reviewed focusing on the basal characteristics, ART outcomes, and adverse pregnancy outcomes. Results There was no difference among the groups' the clinical pregnancy rate or live birth rate. Regarding adverse pregnancy outcomes, the miscarriage rate, multiple pregnancy rate, and prevalence of preterm delivery and pregnancy induced hypertension were not different among the four groups. The incidence of small for gestational age infant was higher in the PCOS groups than the tubal factor groups (p<0.02). On the other hand, the morbidity of gestational diabetes mellitus (GDM) was not high in the non-obese PCOS group but was in the obese groups. And in the obese PCOS group, the newborns were heavier than in the other groups (p<0.02). Conclusion Non-obese PCOS presents many differences compared with obese PCOS, not only in the IVF-parameters but also in the morbidity of adverse pregnancy outcomes, especially in GDM and fetal macrosomia.
Mixing Tile Resolutions in Tiled Video: A Perceptual Quality Assessment

The mismatch between increasingly large video resolution and constrained screen size of mobile devices has led to the proposal of zoomable video systems based on tiled video. In the current system, a tiled video frame is constructed from multiple tiles in a single resolution stream. In this paper, we explore the perceptual effect of mixed-resolution tiles in tiled video, in which tiles within a video frame could come from streams with different resolutions, with the aim to tradeoff bandwidth and perceptual video quality. To understand how users perceive the video quality of mixed-resolution tiled video, we conducted a psychophysical study with 50 participants on tiled videos where the tile resolutions are randomly chosen from two resolution levels with equal probability. The experiment results show that in many cases, we can mix tiles from HD (1920×1080p) stream and tiles from 1600×900p stream without being noticed by the viewers. Even when participants notice quality degradation in videos combined with tiles from HD stream and tiles from 960×540p stream, the majority of participants still accept the degradation when viewing videos with low and medium motion; and greater than 40% of participants accept the quality degradation when viewing video with dense motion.
Hoeffding and Bernstein races for selecting policies in evolutionary direct policy search

Uncertainty arises in reinforcement learning from various sources, and therefore it is necessary to consider statistics based on several roll-outs for evaluating behavioral policies. We add an adaptive uncertainty handling based on Hoeffding and empirical Bernstein races to the CMA-ES, a variable metric evolution strategy proposed for direct policy search. The uncertainty handling adjusts individually the number of episodes considered for the evaluation of a policy. The performance estimation is kept just accurate enough for a sufficiently good ranking of candidate policies, which is in turn sufficient for the CMA-ES to find better solutions. This increases the learning speed as well as the robustness of the algorithm.
Time in organizations: Its Experience, . Explanations and Effects

Time is seen as a fundamental but neglected variable in organizational analysis. The paper develops a model of organizational time based upon the notion of a timeframe whereby time is advocated as a socially constructed variable, experienced in the present as represented by a number of variables which form four clusters of time. Explanations of this experience of time in the present derive from the organizational and institutional context. The timeframe of an organization is also seen to affect decision making and learning processes. The timeframe is bounded by knowledge of the past which is used to envision the future. The essential aspect of the past is the extent to which past knowledge can be codified, while the essential aspect of the future is the degree of congru ence over visions of the future. The timeframe model is used to develop scen arios of how knowledge codification and goal congruence can change.
Perception and human interaction for developmental learning of objects and affordances

In this paper we describe a cognitive architecture for humanoids interacting with objects and caregivers in a developmental robotics scenario. The architecture is foundational to the MACSi project: it is designed to support experiments to make a humanoid robot gradually enlarge its repertoire of known objects and skills combining autonomous learning, social guidance and intrinsic motivation. This complex learning process requires the capability to learn affordances first. Here, we present the general framework for achieving these goals, focusing on the elementary action, perception and interaction modules. Preliminary experiments performed on the humanoid robot iCub are also discussed.
Une interprétation de la théorie de la religion selon Max Weber

Par un paradoxe tout à fait conforme à la théorie webérienne de la relation entre Ies intentions des agents et le sens historique de leurs actions, la contribution la plus importante que Max Weber ait apportée à la sociologie de la religion se situe sans doute sur un tout autre terrain que celui qu'il a choisi pour son affrontement de toute une vie avec Marx. Si, dans son effort obstiné pour établir l'efficacité historique des croyances religieuses contre Ies expressions Ies plus réductrices de la théorie marxiste, Max Weber est parfois conduit à une exaltation du charisme qui, comme on l'a remarque, n'est pas sans évoquer une philosophic «héroique» de l'histoire a la manière de Carlyle, par exemple lorsqu'il désigne le chef charismatique comme « la force révolutionnaire spécifiquement ‘créatrice’ de l'histoire » (I), il reste qu'il fournit lui-même le moyen d'échapper à l'alternative simpliste dont ses analyses Ies plus incertaines sont le produit, c'est-à-dire à l'opposition entre l'illusion de l'autonomie absolue portant à concevoir le message religieux comme surgissement inspiré et la théorie réductrice qui en fait le reflet direct des conditions économiques et sociales: il met en effet en lumière ce que Ies deux positions opposées et complémentaires ont en commun d'oublier, à savoir le travail religieux que réalisent Ies agents et Ies porte-parole spécialisés, investis du pouvoir, institutionnel ou non, de répondre, par un type déterminé de pratiques ou de discours, à une catégorie particulière de besoins propres à des groupes sociaux déterminés.
Feminists, Queers and Critics: Debating the Cuban Sex Trade*

Abstract Cuban scholars and women's advocates have criticised the widespread emergence of sex tourism in post-Soviet Cuba and attributed prostitution to a crisis in socialist values. In response, feminist scholars in the United States and Europe have argued that Cuban analysts promote government agendas and demonise sex workers. Drawing on nineteen months of field research in Havana, I challenge this conclusion to demonstrate how queer Cubans condemn sex tourism while denouncing an unconditional allegiance to Cuban nationalism. By introducing gay Cuban critiques into the debate, I highlight the interventionist undertones of feminist scholarship on the Cuban sex trade. Feministas, Queers y Críticos: Debatiendo el Comercio Sexual Cubano Académicos cubanos y defensores de mujeres han criticado la emergencia generalizada del turismo sexual en la Cuba post-soviética y atribuyen la prostitución a una crisis en los valores socialistas. Como respuesta, académicas feministas en los Estados Unidos y Europa han sostenido que los analistas cubanos promueven agendas gubernamentales y demonizan a los trabajadores sexuales. Apoyándose en 19 meses de investigación de campo en la Habana, en el artículo se desafía esta conclusión para demostrar cómo los queer cubanos condenan al turismo sexual mientras denuncian la alineación incondicional al nacionalismo cubano. Al introducir críticas gay en el debate, se resaltan las tendencias intervencionistas de la academia feminista sobre el comercio sexual cubano. Palabras clave: comercio sexual turista, feminismo, homosexualidad Feministas, Bichas e Críticos: Debates sobre o Mercado de Sexo Cubano Estudiosos cubanos e defensores das mulheres criticam a ampla emergência do turismo sexual na Cuba pós-soviética, atribuindo a prostituição a uma crise dos valores socialistas. Em resposta, estudiosas feministas nos Estados Unidos e Europa argumentam que analistas cubanos promovem agendas governamentais e demonizam trabalhadores do sexo. Com base numa pesquisa de campo de dezenove meses em Havana, eu desafio essa conclusão, para mostrar como cubanos homossexuais condenam o turismo sexual enquanto repudiam uma lealdade incondicional ao nacionalismo cubano. Ao introduzir críticas de cubanos homossexuais no debate, eu sublinho insinuações intervencionistas de estudos feministas sobre o mercado sexual cubano. Palavras-chave: mercado de sexo turístico, feminismo, homessexualidade.
Hair self shadowing and transparency depth ordering using occupancy maps

This paper presents a method for quickly constructing a high-quality approximate visibility function for high frequency semi-transparent geometry such as hair. We can then reconstruct the visibility for any fragment without the expensive compression needed by Deep Shadow Maps and with a quality that is much better than what is attainable at similar framerates using Opacity Maps or Deep Opacity Maps. The memory footprint of our method is also considerably lower than that of previous methods. We then use a similar method to achieve back-to-front sorted alpha blending of the fragments with results that are virtually indistinguishable from depth-peeling and an order of magnitude faster.
Optimal Demand Response for Distribution Feeders With Existing Smart Loads

Load characteristics play an important role in distribution systems, which are traditionally designed to supply peak load; hence, decreasing this peak can considerably reduce overall grid costs. Basic components of smart grids such as smart meters allow two-way communication between the utilities and customers; in this context, controllable smart loads are being introduced, which allow developing and implementing energy management systems for customers and distribution feeders. Therefore, this paper studies the impact of existing smart loads, in particular Peaksaver PLUS (PS+) loads in ON, Canada, to reduce summer peak loads for distribution feeders. A neural network model of controllable loads is developed and integrated into an unbalanced distribution optimal power flow (DOPF) model to optimally control tap changers and switched capacitors, as well as sent signals to programmable thermostats of air conditioners in residential buildings, in particular those associated with the PS+ program. The developed integrated DOPF is tested and validated using a practical system, demonstrating the benefits of using existing controllable loads to optimally operate distribution feeders.
Author Verification: Exploring a Large set of Parameters using a Genetic Algorithm - Notebook for PAN at CLEF 2014

In this paper we present the system we submitted to the PAN'14 competition for the author verification task. We consider the task as a supervised classification problem, where each case in a dataset is an instance. Our system works by applying the same combination of parameters to every case in a dataset. Thus, the training stage consists in finding an optimal combination of parameters which maximizes the performance on the training data using cross-validation. This is achieved using a simple genetic algorithm, since the space of all possible combinations is impractical.
Continuous and Simultaneous Gesture and Posture Recognition for Commanding a Robotic Wheelchair; Towards Spotting the Signal Patterns

Spotting signal patterns with varying lengths has been still an open problem in the literature. In this study, we describe a signal pattern recognition approach for continuous and simultaneous classification of a tracked hand's posture and gestures and map them to steering commands for control of a robotic wheelchair. The developed methodology not only affords 100\% recognition accuracy on a streaming signal for continuous recognition, but also brings about a new perspective for building a training dictionary which eliminates human intervention to spot the gesture or postures on a training signal. In the training phase we employ a state of art subspace clustering method to find the most representative state samples. The recognition and training framework reveal boundaries of the patterns on the streaming signal with a successive decision tree structure intrinsically. We make use of the Collaborative ans Block Sparse Representation based classification methods for continuous gesture and posture recognition.
Meta-Analysis and the Psychology of Gender Differences

Psychological research on gender differences has had a long, and sometimes dishonorable, history spanning more than a century. ' The research ranges from early efforts to measure the cranial capacities of males and females to the current sophisticated metaanalyses of psychological gender differences. Here I will briefly review the history of research on gender differences, focusing particularly on the issue of gender differences in cognitive abilities, and then move to a discussion of recent meta-analyses of psychological gender differences.

The Impact of Knowledge of Suicide Prevention and Work Experience among Clinical Staff on Attitudes towards Working with Suicidal Patients and Suicide Prevention

Suicide-preventive training has shown to influence attitudes. This study aimed at investigating what impact other factors than knowledge might have on attitudes towards work with suicidal patients and suicide prevention. In 2007, 500 health-care staff working in a psychiatric clinic in Stockholm received a questionnaire with items concerning work with suicidal patients to which 358 (71.6%) responded. A set of attitude items were tested using structural equation modelling (LISREL). Three models were found to be satisfactory valid and reliable: Job clarity, Job confidence and Attitudes towards prevention. These were then used in regression analyses as dependent variables with predictors such as experience of work with suicidal patients, perceived sufficient training, age and gender. Perceived sufficient training was consistently the most important predictor for all three attitude concepts (p < 0.01, β = 0.559 for Job clarity; p < 0.01, β = 0.53 for Job confidence; p < 0.01, β = 0.191 for Attitudes towards prevention). Age was another significant predictor for Job clarity (p < 0.05, β = 0.134), as was experience of patient suicide for Job confidence (p < 0.05, β = 0.137). It is concluded that providing suicide preventive education is likely to improve attitudes towards the prevention of suicide, clarity and confidence regarding their role in the care for suicidal patients. These improvements may contribute to the prevention of suicide in health care settings.
Conceptual Graphs with Relators and Roles

The importance of relations for conceptual modelling motivates an evaluation of Conceptual Graphs (CG) in this respect. This analysis is presented on the formal ontological basis provided by the General Formal Ontology (GFO). On the basis of a simple example domain, modelling problems are identified and analyzed in connection with more sophisticated relational concepts like roles, relators, and player universals. This leads to a proposal for enhancing CGs and their diagrammatic modelling framework in order to capture the example domain more adequately. The newly introduced Conceptual Graphs with Relators allow for expressing roles and relators and help to clarify the ambiguous translation of classical CG relations to relators and roles. From a more general point of view, the overall approach provides an example of applying formal ontological theories in the meta-analysis of modelling language semantics. The role of formal ontology in today’s scientific discourse on conceptual modelling cannot be neglected: it is perceived as both the panacea regarding the future goal of incorporating a more tight semantic basis into modelling as well as an appropriate tool for a large variety of bread-and-butter modelling tasks. The following approach will focus the application of formal ontology in making expressiveness problems explicit that occur in practical modelling with Conceptual Graphs (Cgs). The investigation will center around a simple, but non-trivial modelling example: a concrete act of lending a book and the abstract definition of the underlying trust relation. After introducing the example domain and applying Cgs to achieve a first, simple diagrammatic representation that does not suffice to represent the domains richness, the next steps lead to a formal ontological; this will allow to make the requirements explicit that previously classified these first concept graphs as “unsatisfactory”: the absence of relator concepts and roles. As these demands are unsatisfiable in the standard Cg modelling paradigm, an enhancement of Cg will be proposed that will allow to give a concise model of the example domain. The following (meta-)investigation will combine two well worked-out fields in order to solve a practical modelling problem. The feedback from formal ontology will prepare the introduction of a novel enhancement of Cgs with relators and roles; these will allow for easier application of these graphs in the modelling of relations as well as provide a (semi-)formal semantics which will eliminate misunderstandings regarding the classical Cg relations.
Solving the Nation's Ills Through War: Italy, the Great War, and Nation Building

This study surveys the widely held view in the years leading up to the First World War that Italy required a war to complete its unification process. Intellectuals and activists from across the political spectrum came to accept the view that Italian territorial unity had mostly been achieved by 1870, but that an Italian national consciousness, that bound together north and south, urban and rural, bourgeois and proletariat, had yet to be achieved. Many of these individuals also came to believe that war would create this national consciousness as Italy strove to expand its colonial empire and conquer the Italian lands held by the Austrian-Hungarian Empire. Such commitment to war as the solution to the nation's various ills was instrumental in pushing Italy from its initial neutrality in 1914 to its declaration of war against its former allies in 1915.
Revealing Task Driven Knowledge Worker Behaviors in Open Source Software Communities

Collaborative activities among knowledge workers such as software developers underlie the development of modern society, but the in-depth understanding of their behavioral patterns in open online communities is very challenging. The availability of large volumes of data in open-source software (OSS) repositories (e.g. bug tracking data, emails, and comments) enables us to investigate this issue in a quantitative way. In this paper, we conduct an empirical analysis of online collaborative activities closely related to assure software quality in two well-known OSS communities, namely Eclipse and Mozilla. Our main findings include two aspects: (1) developers exhibit two diametrically opposite behavioral patterns in spatial and temporal scale when they work under two different states (i.e. normal and overload), and (2) the processing times (including bug fixing times and bug tossing times) follow a stretched exponential distribution instead of the common power law distribution. Our work reveals regular patterns in human dynamics beyond online collaborative activities among skilled developers who work under different task-driven load conditions, and it could be an important supplementary to the current work on human dynamics.
Multi-agent approach to network intrusion detection

Our demo presents an agent-based intrusion detection system designed for deployment on high-speed backbone networks. The major contribution of the system is the integration of several anomaly detection techniques by means of collective trust modeling within a group of collaborative detection agents, each featuring a specific detection algorithm. The principal role of anomalies is to provide the input into the trust modeling stage of the detection, where each agent determines the flow trustfulness from aggregated anomalies. The aggregation is performed by extended trust models that model the trustfulness of generalized situated identities, represented by a set of observable features. The system is based on traffic statistics in NetFlow format acquired by dedicated hardware-accelerated network cards, and is able to perform a real-time surveillance of the gigabit networks.
