Redes Neurais Convolucionais na Detecção de Bots Sociais: Um Método Baseado na Clusterização de Mensagens Textuais

Social bots are responsible for malicious activities in social networks. State-of-the-art on social bot detection combines account data with textual content statistics extracted from messages posted in those environments. Nevertheless, statistical consolidation may lead to information loss. In such scenario, this work searches for experimental evidence that supports the hypothesis that the usage of original textual content from messages may improve detection accuracy. To help our search, we developed a method that applies convolutional neural networks to identify suspicious messages based on their original textual content. Those network models are trained on samples selected from clustered messages. Experiments with our method on Twitter data confirm our hypothesis. Resumo. Cada vez mais bots sociais executam atividades maliciosas em redes sociais. O estado da arte na detecção desse tipo de malware considera, entre outras informações, medidas estatísticas calculadas a partir do conteúdo das mensagens postadas nas redes. Como esses cálculos podem ocasionar perda de informação, o presente artigo busca evidências experimentais que apoiem a hipótese de que o uso do conteúdo textual original das mensagens pode aprimorar a precisão de detecção. Para esse fim, foi proposto um método que utiliza redes neurais convolucionais para identificar mensagens e contas suspeitas. Tais redes são treinadas com amostras obtidas pela clusterização dos textos originais das mensagens. Experimentos com o Twitter confirmam a hipótese levantada.
Lighthouse Parenting Programme: Description and pilot evaluation of mentalization-based treatment to address child maltreatment

This article introduces an innovative mentalization-based treatment (MBT) parenting intervention for families where children are at risk of maltreatment. The Lighthouse MBT Parenting Programme aims to prevent child maltreatment by promoting sensitive caregiving in parents. The programme is designed to enhance parents’ capacity for curiosity about their child’s inner world, to help parents ‘see’ (understand) their children clearly, to make sense of misunderstandings in their relationship with their child and to help parents inhibit harmful responses in those moments of misunderstanding and to repair the relationship when harmed. The programme is an adaptation of MBT for borderline and antisocial personality disorders, with a particular focus on attachment and child development. Its strength is in engaging hard to reach parents, who typically do not benefit from parenting programmes. The findings of the pilot evaluation suggest that the programme may be effective in improving parenting confidence and sensitivity and that parents valued the programme and the changes it had helped them to bring about.

Omnidirectional Visual-Servo of a Gough–Stewart Platform

This paper deals with the visual control of the Gough-Stewart platform using a central catadioptric camera observing the platform's legs. This allows a large field of view to be obtained and avoids the occlusion problems observed when a classical perspective camera is used. An automatic and simple method to detect the projections of the leg in the image is also proposed. The control scheme presented here is shown to encompass the classical perspective camera case, as well as catadioptric ones. Finally, experimental results comparing two kinds of visual features (leg directions and leg edges) are described.
A model for evaluating the impact of simulation based learning environments

As the education and training community continues to rapidly embrace simulation based learning for developing practitioners, the task of evaluating the impact of this learning approach is pivotal. Specifically, understanding the learning impact from the field based practitioner point of view is of equal importance to investigating the technical adequacy of the simulation in the training environment. This paper discusses the design and application of a 4 phase model for evaluating simulation based learning which extends evaluation beyond the training environment to the field of application. The model offers examples based on completed evaluation studies with NSW Police Force simulation based learning exercises. The qualitative and quantitative data collection design extended the evaluation process to include listening to the ‘voices from the field’, i.e. the officers’ field based perspective, and offers an insight into the impact of the exercises in relation to application of learning in the field of operation. The model develops an understanding of key elements of the simulation which influence application in the real world i.e. realistic scenarios, real time customised scenario feeds and time constraints. This format of evaluation contributes to the continuous improvement process in the design and delivery of simulation based learning exercises for practitioners. A major finding from the application of the model to two police training based case studies was the differentiation required in levels of realism for achieving learning outcomes. The pre, post, and field based evaluation model has potential for adaption and application across a wide spectrum of simulation based learning which seeks to build the capacity of learners for their respective operational practices.
Researching the glottodidactic potential of selected techniques of working with language material using fMRI

This paper outlines selected results of a glottodidactic study conducted at the Bioimaging Research Center in Kajetany (Poland) using fMRI. The aim of the study was to compare, from the neurolinguistic point of view, selected language activities: retrieving a list of previously memorized words and phrases, retrieving previously memorized short texts, and creating a spontaneous oral statement in a foreign language (L2), in order to assess their potential impact on the development of communicative competence of L2-learners. The study is aimed at answering the following question: the processing of which kind of linguistic information, i.e. in the form of individual phrases or in the form of a text, is more similar to the act of spontaneous speech from the neurobiological perspective. It was assumed that the activity which is more similar to such speech act will probably be more conducive to the development of students' communication skills in the process of learning a foreign language. The results of the study demonstrate that work with a coherent text in foreign language learning and teaching can be more beneficial than working with lists of separate words or phrases.
The effect of smartphone usage on physical capacity 
in young people

Objective: As a necessity of modern life, the duration of smartphone usage is getting longer. The aim of this study was to investigate the relationship between the levels of smart phone use and physical activity and exercise capacities among university students aged 18-25. Methods: Ninety-three volunteer persons (female=50, male=43) who ages between 18 and 25 years participated in the study. Having collected participants demographics informa-tion, smartphone addiction level was assessed by the Smartphone Addiction Scale-Short Version, physical activity level was assessed by International Physical Activity Questionnaire-Short Form and exercise capacities were assessed by 6 Minute Walk Test. Results: It was found that 52.69% of the participants defined themselves as addicted to smartphone use. There was no significant difference in the level of smartphone addiction between male and female individuals. There was no significant difference between participants' daily use of smartphones and physical capacity. However, 67.8% of smartphone users decreased their physical activity levels independently of duration. Conclusion: Our study finds that smartphone usage does not affect the physical capacity of the young age group however, it seems that it may lead to physical inactivity as a psychosocial problem.
Honest advertisement of pairing status: evidence from a tropical resident wood-warbler

Abstract This paper reports the first investigation of the mate attraction function of song in a tropical resident wood-warbler. Male Adelaide’s warblers,Dendroica adelaidae(Emberizidae: Parulinae), which sing two categories of song (A and B), maintain territories and monogamous pair bonds year-round. Males that were naturally or experimentally unpaired delivered A songs at significantly higher rates than did paired males during both breeding and non-breeding periods. In contrast, use of B songs and singing at dawn did not vary with pairing status. The dawn chorus, characterized by intense and versatile displays of the B song category by neighbouring males, was absent from the non-breeding season. Dawn singing and the B song category thus appear relatively unimportant in mate attraction in this species. Results are consistent with the hypothesis that the A song category functions in mate attraction in wood-warblers. Furthermore, data from the non-breeding season show that the mate attraction function of song is not narrowly tied to the breeding season in a resident species. These data provide evidence for honest signalling of male pairing status in a socially monogamous species. Throughout the year, male Adelaide’s warblers reveal their pairing status honestly, with a comparatively higher rate of A song delivery signalling that a male is unpaired. Paired and unpaired males were distinguishable based on their singing behaviour. Honest advertisement of pairing status may have been favoured in this species by female defence of mates and a habitat saturated with territories, which would limit opportunities for polygyny or polyterritoriality.
Comparaisons entre groupes et anonymat dans un environnement numérique : effets sur les performances à des quizz en équipe

Les environnements numériques peuvent être utilisés pour susciter la motivation à apprendre chez les étudiant(e)s, notamment lorsqu'il s'agit des connaissances en informatique et Internet. Dans ce but, un exerciseur a été développé à partir des théories de la comparaison et de l'identité sociale (Festinger, 1954 ; Tajfel, 1978, Tajfel & Turner, 1986). En s'appuyant sur le modèle SIDE (Social Identity model of Deindividuation Effects; Reicher, Spears, & Postmes, 1995; Spears & Lea, 1992) qui prédit que l'anonymat contribue à renforcer la saillance de l'identité de groupe, l'objectif était d'étendre les prédictions de ce modèle aux performances à des tests de connaissances (quizz). En effet, rares sont les études qui ont examiné les effets conjoints de l'anonymat et de la comparaison sociale sur les performances dans les environnements numériques (Michinov, Michinov, & ToczekCapelle, 2004) ou physiques d'apprentissage (Monteil, 1988 ; Monteil & Huguet, 1993).
Co-Management of Protected Areas in South Asia with Special Reference to Bangladesh

Evolution of co-management practices for forests and protected areas ( PAs) is presented for South Asian region in order to comprehend the present co-management scenario in the region in general and Bangladesh in particular. This follows a review of current patterns of co-managing PAs in six main South Asian countries (India, Nepal, Sri Lanka, Pakistan, Bhutan and Bangladesh) with a view to discern enabling co-management policy issues and challenges. The relevance of emerging lessons is examined for Bangladesh in order to help decide future co-management priorities for the PAs. Co-management approach is particularly found suitable for Bangladesh PAs that are intimately interspersed with local communities, who practice cultivation and depend on forests for their livelihood. The protection of PAs and constituent biodiversity against biotic pressure cannot be effectively checked without establishing gainful partnerships with local stakeholders. More natural forest areas should be brought under PAs where co-management practices for in-situ biodiversity conservation should be implemented.
A Systematic Literature Review of Empirical Studies on Decentralized Nursing Stations

Objectives: The objective of this systematic review of literature was to critically evaluate peer-reviewed evidence regarding the effectiveness of decentralized nurse stations (DNSs). Background: The DNS has become an important topic in healthcare design research and practice over the past decade with aims of improving staff efficiency and patient experience. Research has shown to be inconclusive, with studies reporting an assortment of mixed findings. Method: A systematic review of literature was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses search process of electronic databases, citation tracking, and manual searches of references. All authors evaluated the studies independently. Studies included were empirical, peer-reviewed investigations of DNS in hospitals over the past 15 years. Each study was evaluated using an accepted healthcare design evaluation framework. Results: Over 200 studies were identified. After exclusions, 21 studies published since 2003 were available for full evaluation. Key findings from this review include (a) there is a positive trend toward patient experience in units with DNS, (b) nursing teamwork was perceived to decline in units with DNS, (c) methodological issues may be responsible for the mixed and inconsistent findings, and (d) there is no consistent categorization of nurse station typology or standard definition for DNS. Conclusions: Based on the evaluation framework, DNS are supportive of the patient experience yet have a negative impact on nursing teamwork. Higher quality studies are needed to classify specific typologies of DNS and account for elements such as patient care models, communication, visibility, and other patient care–related factors.

Prijsdynamiek van commercieel vastgoed in de EU: cheaper is better: Inzichten in risico-rendementsverhoudingen

Sinds de crisis is er aanzienlijk meer aandacht voor de risico’s op de vastgoedmarkt. Risico’s zijn inherent verbonden aan rendement: meer risico gaat gepaard met meer rendement. Dit artikel laat zien dat er opmerkelijke verschillen zijn in de verhouding tussen risico en rendement voor Europees commercieel vastgoed per marksegment. De resultaten suggereren dat de verhouding voor goedkoper vastgoed beter is dan voor duurder vastgoed. Tijdens de crisis was dit verband nog sterker aanwezig.
Efficient light field computation for view range expansion using viewpoint reduction

In this paper, we present an improved light field display method with wider view range. In our system, two stacked transparent LCDs are used for glasses-free light field display. They modulate the uniform backlight which enters the observer's eyes to approximate the desired light field. The patterns displayed on the LCDs are optimized according to the target light field using an algorithm based on nonnegative matrix factorization (NMF). In order to achieve wider view range and reduce the computational complexity of the pattern optimization, we utilize a small number of sampling views of the light field. To properly choose the subset of the sampling views, a stochastic sampling algorithm is adopted. The effectiveness of the proposed method is demonstrated by the experimental results, and similar light field display results can be generated with reduced sampling views.
O uso de fosfitos no manejo de doenças fúngicas em fruteiras e soja.

The utilization of phosphorus-based fertilizers in many different types of crops is becoming a common practice nowadays. Furthermore, there are several reports about phosphites being used as antifungal agents, inhibiting mycelial growth or acting as elicitors of induced systemic resistance in plants. In this revision a series of reports about the usage of phosphites on different fruit crops and on soybean is presented, showing the great potencial of this important tool for plant disease management.
A CYTOCHEMICAL STUDY OF THE L.E. BODIES OF SYSTEMIC LUPUS ERYTHEMATOSUS

The composition, with respect to nucleic acids, of the L.E. bodies resulting from the action of the plasma of patients with systemic lupus erythematosus on substrate leukocyte nuclei in different kinds of preparations was compared microspectrophotometrically with that of control lymphocyte nuclei. Binding of the basic dye methyl green to DNA was uniformly found to be depressed in L.E. bodies as compared with control nuclei. Since Feulgen-revealed DNA, which served as a standard of reference, was relatively unchanged in amount, the Feulgen:methyl green ratios of L.E. bodies were higher than those of lymphocyte nuclei. Acetylation, which covers basic groups of proteins, was found to increase methyl green uptake by DNA of L.E. bodies to values approximating those of control nuclei, with consequent revision, after acetylation of the Feulgen: methyl green ratios of L.E. bodies to values similar to those of lymphocyte nuclei. Ribonuclease was found to reduce methyl green staining; extraction with dilute acid had little effect. These data have been interpreted to indicate (a) the presence in L.E. bodies of DNA-associated proteins whose basic groups compete with the cationic dye for binding sites of DNA and so inhibit methyl green staining, and (b) the DNA itself is not detectibly altered in state or degree of polymerization. Photometric comparison of the mean Feulgen-stainable DNA content per L.E. body with that of control nuclei showed that DNA is not lost in the L.E. transformation of nuclei.
An interface for post-match play-by-play analysis of a fighting game based on the two players' eye movements

In this paper, we propose an interface to support post-match play-by-play analysis of a hand-to-hand fighting game based on the two players' eye movements. In the domain of e-Sports, the "fighting game" genre refers to hand-to-hand combat games in which two players fight each other by manipulating their respective martial artist characters within the same game screen. An e-Sports match, like a professional chess match, is followed by analysis and commentary about the performance of the players. In this study, we constructed an interface for visualizing information about the match based on the players' eye movements to facilitate post-match play-by-play analysis and commentary. Our interface highlights commonalities and differences in the areas on the screen where the players focus their attention, as well as commonalities and differences in the direction of their eye movements.
Arousal Effects on Pupil Size, Heart Rate, and Skin Conductance in an Emotional Face Task

Arousal level changes constantly and it has a profound influence on performance during everyday activities. Fluctuations in arousal are regulated by the autonomic nervous system, which is mainly controlled by the balanced activity of the parasympathetic and sympathetic systems, commonly indexed by heart rate (HR) and galvanic skin response (GSR), respectively. Although a growing number of studies have used pupil size to indicate the level of arousal, research that directly examines the relationship between pupil size and HR or GSR is limited. The goal of this study was to understand how pupil size is modulated by autonomic arousal. Human participants fixated various emotional face stimuli, of which low-level visual properties were carefully controlled, while their pupil size, HR, GSR, and eye position were recorded simultaneously. We hypothesized that a positive correlation between pupil size and HR or GSR would be observed both before and after face presentation. Trial-by-trial positive correlations between pupil diameter and HR and GSR were found before face presentation, with larger pupil diameter observed on trials with higher HR or GSR. However, task-evoked pupil responses after face presentation only correlated with HR. Overall, these results demonstrated a trial-by-trial relationship between pupil size and HR or GSR, suggesting that pupil size can be used as an index for arousal level involuntarily regulated by the autonomic nervous system.
Vessel-Wall Magnetic Resonance Imaging of Intracranial Atherosclerotic Plaque and Ischemic Stroke: A Systematic Review and Meta-Analysis

Introduction: Vessel-wall magnetic resonance imaging (MRI) has been suggested as a valuable tool for assessing intracranial arterial stenosis with additional diagnostic features. However, there is limited conclusive evidence on whether vessel-wall MR imaging of intracranial atherosclerotic plaques provides valuable information for predicting vulnerable lesions. We conducted this systematic review and meta-analysis to evaluate which characteristics of intracranial-plaque on vessel-wall MRI are markers of culprit lesions. Methods: The MEDLINE, EMBASE, and Cochrane Library of Clinical Trials databases were searched for studies reporting the association between vessel-wall MRI characteristics of intracranial plaque and corresponding stroke events. Odds ratios (ORs) for the prevalence of stroke with intracranial-plaque MRI characteristics were pooled in a meta-analysis using a random-effects model. Results: Twenty studies were included in this review. We found a significant association between plaque enhancement (OR, 10.09; 95% CI, 5.38–18.93), positive remodeling (OR, 6.19; 95% CI, 3.22–11.92), and plaque surface irregularity (OR, 3.94; 95% CI, 1.90–8.16) with stroke events. However, no significant difference was found for the presence of eccentricity (OR, 1.22; 95% CI, 0.51–2.91). Conclusion: Based on current evidence, intracranial plaque contrast enhancement, positive remodeling, and plaque irregularity on MRI are associated with increased risk of stroke events. Our findings support the design of future studies on intracranial-plaque MRI and decision making for the management of intracranial atherosclerotic plaques.
