    Stunning imagery helps make astronomy one of the most popular sciences -- but what types of astronomy images are most popular? To help answer this question, public response to images posted to various public venues of the Astronomy Picture of the Day (APOD) are investigated. APOD portals queried included the main NASA website and the social media mirrors on Facebook, Google Plus, and Twitter. Popularity measures include polls, downloads, page views, likes, shares, and retweets; these measures are used to assess how image popularity varies in relation to various image attributes including topic and topicality.

  2. Images of Freud in Popular Culture and Fiction

    DEFF Research Database (Denmark)

    Sørensen, Bent

    Historiographic metafiction and postmodern pastiche, both defined by critic Linda Hutcheon as subversive literary and cultural strategies, have put Freud to work both as a clown and a stern cultural critic. My paper will first take a lighthearted look at some of the humorous images we find of Freud...... in popular culture, where Sigmund has long had iconic status, both in terms of his own physical likeness and in terms of stereotyped versions of his main ideas. To complement this analysis I shall contrast the popular image of Freud with the use of him in recent fiction by E.L. Doctorow and John Irving....

    Cloud resources nowadays contribute an essential share of resources for computing in high-energy physics. Such resources can be either provided by private or public IaaS clouds (e.g. OpenStack, Amazon EC2, Google Compute Engine) or by volunteers computers (e.g. LHC@Home 2.0). In any case, experiments need to prepare a virtual machine image that provides the execution environment for the physics application at hand. The CernVM virtual machine since version 3 is a minimal and versatile virtual machine image capable of booting different operating systems. The virtual machine image is less than 20 megabyte in size. The actual operating system is delivered on demand by the CernVM File System. CernVM 3 has matured from a prototype to a production environment. It is used, for instance, to run LHC applications in the cloud, to tune event generators using a network of volunteer computers, and as a container for the historic Scientific Linux 5 and Scientific Linux 4 based software environments in the course of long-term data preservation efforts of the ALICE, CMS, and ALEPH experiments. We present experience and lessons learned from the use of CernVM at scale. We also provide an outlook on the upcoming developments. These developments include adding support for Scientific Linux 7, the use of container virtualization, such as provided by Docker, and the streamlining of virtual machine contextualization towards the cloud-init industry standard.

    CernVM virtual machine is a Linux based virtual appliance optimized for High Energy Physics experiments. It is used for cloud computing, volunteer computing, and software development by the four large LHC experiments. The goal of this project is proling and optimizing the boot process of the CernVM. A key part was the development of a performance profiler for shell scripts as an extension to the popular BusyBox open source UNIX tool suite. Based on the measurements, costly shell code was replaced by more efficient, custom C programs. The results are compared to the original ones and successful optimization is proven.

    The increase in the popularity of social media has shattered the gap between the physical and virtual worlds. The content generated by people or social sensors on social media provides information about users and their living surroundings, which allows us to access a user's preferences, opinions, and interactions. This provides an opportunity for us to understand human behavior and enhance the services provided for both the real and virtual worlds. In this paper, we will focus on the popularity prediction of social images on Flickr, a popular social photo-sharing site, and promote the research on utilizing social sensory data in the context of assisting people to improve their life on the Web. Social data are different from the data collected from physical sensors; in the fact that they exhibit special characteristics that pose new challenges. In addition to their huge quantity, social data are noisy, unstructured, and heterogeneous. Moreover, they involve human semantics and contextual data that require analysis and interpretation based on human behavior. Accordingly, we address the problem of popularity prediction for an image by exploiting three main factors that are important for making an image popular. In particular, we investigate the impact of the image's visual content, where the semantic and sentiment information extracted from the image show an impact on its popularity, as well as the textual information associated with the image, which has a fundamental role in boosting the visibility of the image in the keyword search results. Additionally, we explore social context, such as an image owner's popularity and how it positively influences the image popularity. With a comprehensive study on the effect of the three aspects, we further propose to jointly consider the heterogeneous social sensory data. Experimental results obtained from real-world data demonstrate that the three factors utilized complement each other in obtaining promising results in the

    To discuss representations of nursing in popular culture using the Contemporary Gothic theory. Nursing is stereotypically known as a caring profession. Caring in both the natural and professional perspectives is inextricably attached to love and love, we are told, is universal. In popular culture, however, there are numerous examples of nurses being portrayed in ways where love - its expression and its practice - has been transgressed or tainted. Exploring this dark side of nursing, even if fictitious, is significant because it illuminates social and cultural tensions. Discussion Paper. CINAHL, Scopus and Humanities International Databases were searched for terms related to nursing, love, abject and the gothic, published between 1990 - 2016. Four popular culture texts which ranged in genre and gothic elements were selected for analysis. The types of transgressive love these nurses express to patients ranges from the obsessive and the pornographic, to the monstrous. We suggest this positioning illuminates a hidden reality that nursing work is at once intimate and personal but also hidden, profane, repellent, horrifying and feared. Nursing's allure for storytellers may rest in its association with the abject. How nurses find redemption, satisfaction and meaning in these locations is relevant for how we can imbue our lives and work with greater humanity. The Contemporary Gothic is a useful tool in exposing and exploring ambiguous, challenging and taboo aspects of nursing in society. Such and analysis helps to explain phenomena - including nursing itself - which exists in the shadow of dominant and often stereotyped discourses. This article is protected by copyright.

    2011-06-01

    Full Text Available The ventromedial prefrontal cortex (vmPFC is believed to be important in everyday preference judgments, processing emotions during decision-making. However, there is still controversy in the literature regarding the participation of the vmPFC. To further elucidate the contribution of the vmPFC in brand preference, we designed a functional magnetic resonance imaging (fMRI study where 18 subjects assessed positive, indifferent and fictitious brands. Also, both the period during and after the decision process were analyzed, hoping to unravel temporally the role of the vmPFC, using modeled and model-free fMRI analysis. Considering together the period before and after decision-making, there was activation of the vmPFC when comparing positive with indifferent or fictitious brands. However, when the decision-making period was separated from the moment after the response, and especially for positive brands, the vmPFC was more active after the choice than during the decision process itself, challenging some of the existing literature. The results of the present study support the notion that the vmPFC may be unimportant in the decision stage of brand preference, questioning theories that postulate that the vmPFC is in the origin of such a choice. Further studies are needed to investigate in detail why the vmPFC seems to be involved in brand preference only after the decision process.

    The consumption of yogurt in Western countries has risen for over a century, first slowly, then more rapidly. The purpose of the present study was to investigate this prolonged phase of growth, by examining the popularity and the projected image of yogurt. A particular focus was on the way these aspects were reflected in consumption patterns and media representations. The data showed how during its period of rapid popularization, yogurt's visibility in the media greatly increased. It was concluded that the product's image was highly flexible in post-war decades, evidenced by the multi-pronged approach taken by marketers. Yogurt was not only advertised as both tasty and healthy, but also as natural and convenient, a strategy that appears to have been informed by consumers' preferences and existing cultural values. This demonstrates how a high degree of product differentiation and diversification during a product's growth stage can result in a heterogeneous image, allowing for a broad range of marketing strategies.

    The present study extends research on thinspiration images, visual and/or textual images intended to inspire weight loss, from pro-eating disorder websites to popular photo-sharing social media websites. The article reports on a systematic content analysis of thinspiration images (N=300) on Twitter and Pinterest. Images tended to be sexually suggestive and objectifying with a focus on ultra-thin, bony, scantily-clad women. Results indicated that particular social media channels and labels (i.e., tags) were characterized by more segmented, bony content and greater social endorsement compared to others. In light of theories of media influence, results offer insight into the potentially harmful effects of exposure to sexually suggestive and objectifying content in large online communities on body image, quality of life, and mental health.

    Music can induce different emotions. However, its neural mechanism remains unknown. The aim of this study was to use functional magnetic resonance imaging (fMRI) and position emission tomography (PET) imaging for mapping of neural changes under the most popular music in healthy volunteers. Blood-oxygen-level-dependent (BOLD) fMRI and monoamine receptor PET imaging with {sup 11}C-N-methylspiperone ({sup 11}C-NMSP) were conducted under the popular music Gangnam Style and light music A Comme Amour in healthy subjects. PET and fMRI images were analyzed by using the Statistical Parametric Mapping software (SPM). Significantly increased fMRI BOLD signals were found in the bilateral superior temporal cortices, left cerebellum, left putamen and right thalamus cortex. Monoamine receptor availability was increased significantly in the left superior temporal gyrus and left putamen, but decreased in the bilateral superior occipital cortices under the Gangnam Style compared with the light music condition. Significant positive correlation was found between {sup 11}C-NMSP binding and fMRI BOLD signals in the left temporal cortex. Furthermore, increased {sup 11}C-NMSP binding in the left putamen was positively correlated with the mood arousal level score under the Gangnam Style condition. Popular music Gangnam Style can arouse pleasure experience and strong emotional response. The left putamen is positively correlated with the mood arousal level score under the Gangnam Style condition. Our results revealed characteristic patterns of brain activity associated with Gangnam Style, and may also provide more general insights into the music-induced emotional processing. (orig.)

    In today's societies, successful new medical imaging technologies have focused unprecedented attention on the inside of the human body. These techniques have jumped the walls of the biomedical field per se, penetrating the fields of culture and law. The article traces a genealogy of twentieth-century medical techniques used to visualize the human body and brain, from X-rays to the more sophisticated CTs, MRIs, and PET scans. It explores the changes that these ever more numerous visualization techniques have occasioned in our corporality and examines how these technologies have been received in the courtroom and in popular culture, especially in literature, movies, and magazines.

    Full Text Available This research is aimed at revealing the new image of American popular heroes as depicted in the novel adaptation film of The Hunger Games which is created as a trilogy, which consists of two more novels: Catching Fire and Mockingjay. This film is one of the most phenomenal films in 2013-2104, which grossed out up to $407,999,255. This research used textual approach, which focused on the text as the object, that is The Hunger Games film. The result shows that The Hunger Games essentially brings the issue of slavery back into scrutiny. However, the creation of the heroin in the film is granted as the reconstruction of popular heroes in America. She is an inspiring female hero which is exemplified as the appreciation of womens values. Yet, the heroin is broadly defined with the qualities of rouge heroes as the characteristics are the representation of the belief and values associated with freedom to wash away the oppression restore the rights of the minority. In addition to the issue of slavery , the symbols of new hope and new spirit are implicitly emerged in the story. This attempt was proficiently done by the heroin, which was eventually created as the new image of the American heroes.

    The CERN Virtual Machine (CernVM) Software Appliance is a project developed in CERN with the goal of allowing the execution of the experiment's software on different operating systems in an easy way for the users. To achieve this it makes use of Virtual Machine images consisting of a JEOS (Just Enough Operating System) Linux image, bundled with CVMFS, a distributed file system for software. This image can then be run with a proper virtualizer on most of the platforms available. It also aggressively caches data on the local user's machine so that it can operate disconnected from the network. CMS wanted to compare the performance of the CMS Software running in the virtualized environment with the same software running on a native Linux box. To answer this wish, a series of tests were made on a controlled environment during 2010-2011. This work presents the results of those tests.

    In this paper, we examine the biological immune system as an autonomic system for self-protection, which has evolved over millions of years probably through extensive redesigning, testing, tuning and optimization process. The powerful information processing capabilities of the immune system, such as feature extraction, pattern recognition, learning, memory, and its distributive nature provide rich metaphors for its artificial counterpart. Our study focuses on building an autonomic defense system, using some immunological metaphors for information gathering, analyzing, decision making and launching threat and attack responses. In order to detection Stuxnet like malware, we propose to include a secure VM (or dedicated host) to the SCADA Network to monitor behavior and all software updates. This on-going research effort is not to mimic the nature but to explore and learn valuable lessons useful for self-adaptive cyber defense systems.

    The Stanford Linear Accelerator Center is a single purpose laboratory operated by Stanford University for the Department of Energy. Its mission is to do research in High Energy (particle) physics. This research involves the use of large and complex electronic detectors. Each of these detectors is a multi-million dollar device. A part of each detector is a computer for process control and data logging. Most detectors at SLAC now use VAX 11/780s for this purpose. Most detectors record digital data via this process control computer. Consequently, physics today is not bounded by the cost of analog to digital conversion as it was in the past, and the physicist is able to run larger experiments than were feasible a decade ago. Today a medium sized experiment will produce several hundred full reels of 6250 BPI tape whereas a large experiment is a couple of thousand reels. The raw data must first be transformed into physics events using data transformation programs. The physicists then use subsets of the data to understand what went on. The subset may be anywhere from a few megabytes to 5 or 6 gigabytes of data (30 or 40 full reels of tape). This searching would be best solved interactively (if computers and I/0 devices were fast enough). Instead what we find are very dynamic batch programs that are generally changed every run. The result is that on any day there are probably around 50 to 100 physicists interacting with a half dozen different experiments who are causing us to mount around 750 to 1000 tapes a day. This has been the style of computing for the last decade. Our going to VM is part of our effort to change this style of computing and to make physics computing more effective.

    The $\\mu$CernVM will be the successor of the CernVM as a new appliance to help with accessing LHC for data analysis and development. CernVM has a web appliance agent that facilitates user interaction with the virtual machine and reduces the need for executing shell commands or installing graphical applications for displaying basic information such as memory usage or performing simple tasks such as updating the operating system. The updates are done differently in the $\\mu$CernVM than mainstream Linux distributions. Its filesystem is a composition of a read-only layer that exists in the network and a read/write layer that is initilised on first boot and keeps the user changes afterwards. Thus, means are provided to avoid loss of user data and system instabilities when the operating system is updated by fetching a new read-only layer.

    CernVM is a virtual software appliance designed to support the development cycle and provide a runtime environment for the LHC experiments. It consists of three key components that differentiate it from more traditional virtual machines: a minimal Linux Operating System (OS), a specially tuned file system designed to deliver application software on demand, and contextualization tools that provide a means to easily customize and configure CernVM instances for different tasks and user communities. In this contribution we briefly describe the most important use cases for virtualization in High Energy Physics (HEP), CernVM key components and discuss how end-to-end systems corresponding to these use cases can be realized using CernVM.

    2011-11-01

    Full Text Available In virtualized environments, performance interference between virtual machines (VMs is a key challenge. In order to mitigate resource contention, an efficient VM scheduling is positively necessary.In this paper, we propose a workload-aware VM scheduler on multi-core systems, which finds a systemwide mapping of VMs to physical cores. Our work aims not only at minimizing the number of used hosts,but at maximizing the system throughput. To achieve the first goal, our scheduler dynamically adjusts a set of used hosts. To achieve the second goal, it maps each VM on a physical core where the physical core and its host most sufficiently meet the resource requirements of the VM. Evaluation demonstrates that our scheduling ensures efficient use of data center resources.

  11. Comprehensive performance analysis of popular odd-symmetric phase masks used for wave-front coded imaging system

    Science.gov (United States)

    Zhao, Hui; Li, Yingcai

    2010-11-01

    Wave-front coding was proposed in 1995 and is a powerful system-level technique used to extend the depth of field (DOF) of incoherent imaging system. The key to wave-front coding lies in the design of suitable phase masks which make the imaging system insensitive to defocus and defocus-related aberrations. Among all phase masks used for wave-front coding, odd-symmetric types are dominant and can provide larger extended DOF. With the acceptable degradation of MTF (Modulation Transfer Function) taken as a criterion, optimization procedure is used to obtain the optimum parameters for popular odd-symmetric phase masks and then a comprehensive analysis is carried out by considering four factors: DOF extension capability, sensitiveness to elementary aberrations, PSF (Point Spread Function) shifting effect and restorability of intermediate blurred images. To the best of our knowledge, the comprehensive analysis on performance of popular odd-symmetric phase masks, as done in this manuscript, has not been made before. So, the work reported here could be considered as a complementary part to the field of wave-front coding.

    2016-02-01

    Full Text Available Fantasies about clones, cyborgs and androids have become part and parcel of the mythology of modern times – the mythologies of the biotechnological era in which the achievements of genetic engineering have inflamed fears of possible abuse of scientific knowledge and the consequences of such abuse. The paper considers the phenomenon of reproductive cloning of human beings as it is represented in popular culture, especially film as it is one of the most important sources of representations and constructions of ideas about clones. After the introductory consideration of this phenomenon in scientific, ethical and media debates which are imbued with rejection of reproductive cloning, I have analyzed the different uses of the clone motif in selected movies. I have examined the structure and content of the genre formula of "social melodrama" which is present in films about clones, and have analyzed the mythical patterns pertaining to the topic of cloning, such as the myth of immortality, the myth of twins, the myth of the uniqueness of human kind etc. Ultimately, the nature and origins of the fear of clones and disgust that clones cause have been examined, and it has been shown that they mostly boil down to the fear of the dehumanization of human beings, the fear of the loss of difference and the transgression of biological, sociocultural and metaphysical boundaries.

  15. Porting of $\\mu$CernVM to AArch64

    CERN Document Server

    Scheffler, Felix

    2016-01-01

    $\\mu$CernVM is a virtual appliance that contains a stripped-down Linux OS connecting to a CernVM-Filesystem (CVMFS) repository that resides on a dedicated web server. In contrast to “usual” VMs, anything that is needed from this repository is only downloaded on demand, aggressively cached and eventually released again. Currently, $\\mu$CernVM is only distributed for x86-64. Recently, ARM (market leader in mobile computing) has started to enter the server market, which is still dominated by x86-64 infrastructure. However, in terms of performance/watt, AArch64 (latest ARM 64bit architecture) is a promising alternative. Facing millions of jobs to compute every day, it is thus desirable to have an HEP virtualisation solution for AArch64. In this project, $\\mu$CernVM was successfully ported to AArch64. Native and virtualised runtime performance was evaluated using ROOT6 and CMS benchmarks. It was found that VM performance is inferior to host performance across all tests. Respective numbers greatly vary between...

    Lately, there is a trend in scientific projects to look for computing resources in the volunteering community. In addition, to reduce the development effort required to port the scientific software stack to all the known platforms, the use of Virtual Machines (VMs)u is becoming increasingly popular. Unfortunately their use further complicates the software installation and operation, restricting the volunteer audience to sufficiently expert people. CernVM WebAPI is a software solution addressing this specific case in a way that opens wide new application opportunities. It offers a very simple API for setting-up, controlling and interfacing with a VM instance in the users computer, while in the same time offloading the user from all the burden of downloading, installing and configuring the hypervisor. WebAPI comes with a lightweight javascript library that guides the user through the application installation process. Malicious usage is prohibited by offering a per-domain PKI validation mechanism. In this contribution we will overview this new technology, discuss its security features and examine some test cases where it is already in use.

    Dai, Wei; Matsubara, Yoichi; Kobayashi, Hisayasu

    2002-06-01

    This article mainly introduces experimental results on a new type pulse tube refrigerator named as V-M type pulse tube refrigerator. The main difference from Stirling type or G-M type pulse tube refrigerator is that thermal compressor similar to that of a V-M cryocooler is used instead of mechanical compressor. By using temperature difference between room temperature and liquid nitrogen, pressure wave with high to low pressure ratio around 1.2 is obtained. This pressure wave is used to generate cooling effect at the cold end. With a 20 K pre-cooler, this machine reaches lowest temperature 5.25 K by using helium 4 at 0.77 Hz, 19 bar charge pressure. DC flow plays an important role in our system. It not only influences the final obtainable lowest temperature, but also is used to increase cold end cool-down speed. Total volume of the V-M type pulse tube refrigerator is around 3.3 l. However, dead volume inside rotor housing occupies about 2.8 l and can be much reduced.

    Full Text Available Cloud computing is a fast growing area in computing research and industry today. With the advancement of the Cloud, there are new possibilities opening up on how applications can be built and how different services can be offered to the end user through Virtualization, on the internet. There are the cloud service providers who provide large scaled computing infrastructure defined on usage, and provide the infrastructure services in a very flexiblemanner which the users can scale up or down at will. The establishment of an effective load balancing algorithm and how to use Cloud computing resources efficiently for effective and efficient cloud computing is one of the Cloud computing service providers’ultimate goals. In this paper firstly analysis of different Virtual Machine (VM load balancing algorithms is done. Secondly, a new VM load balancing algorithm has been proposed and implemented for an IaaS framework in Simulated cloud computing environment; i.e. ‘Weighted Active Monitoring Load Balancing Algorithm’ using CloudSimtools, for the Datacenter to effectively load balance requests between the available virtual machines assigning a weight, in order to achieve better performance parameters such as response time and Data processing time.

    To support the effort to eliminate the Syrian Arab Republic chemical weapons stockpile safely, there was a requirement to provide scientific advice based on experimentally derived information on both toxicity and medical countermeasures (MedCM) in the event of exposure to VM, VX or VM-VX mixtures. Complementary in vitro and in vivo studies were undertaken to inform that advice. The penetration rate of neat VM was not significantly different from that of neat VX, through either guinea pig or pig skin in vitro. The presence of VX did not affect the penetration rate of VM in mixtures of various proportions. A lethal dose of VM was approximately twice that of VX in guinea pigs poisoned via the percutaneous route. There was no interaction in mixed agent solutions which altered the in vivo toxicity of the agents. Percutaneous poisoning by VM responded to treatment with standard MedCM, although complete protection was not achieved.

    2015-01-01

    The CernVM-File System (CVMFS) delivers experiment software installations to thousands of globally distributed nodes in the WLCG and beyond. In recent years it became a mission-critical component for offline data processing of the LHC experiments and many other collaborations. From a software engineering perspective, CVMFS is a medium-sized C++ system-level project. Following the growth of the project, we introduced a number of measures to improve the code quality, testability, and maintainability. In particular, we found very useful code reviews through github pull requests and automated unit- and integration testing. We are also transitioning to a test-driven development for new features and bug fixes. These processes are supported by a number of tools, such as Google Test, Jenkins, Docker, and others. We would like to share our experience on problems we encountered and on which processes and tools worked well for us.

    The current study investigated the effects of brief exposure to appearance-related media on young girls' body image. One hundred and twenty-one girls aged 3-6 years old participated. Results indicated that exposure did not affect body dissatisfaction or engagement in appearance-related play behaviours. This is the first empirical study to provide support for previous findings that suggest media exposure does not affect body image in young girls. In contrast to older populations, it is possible that young children may adopt the persona of attractive characters with whom they identify rather than comparing themselves to the characters. Although nearly all girls liked the way they looked, self-report data indicated that nearly one-third of the participants would change something about their physical appearance and nearly half of the girls worried about being fat. Exposure to appearance-related media did not exacerbate concerns.

    Forty-four patients who were suspected hypopharyngeal carcinoma underwent both conventional CT under quiet breath holding and helical CT under Valsalva maneuver (VMCT). All patients successfully performed Valsalva maneuver during image acquisition. Normal piriform fossae were dilated well under VM. Five fossae involved by hypopharyngeal carcinoma were poorly dilated on VMCT. In conclusion VMCT is a supportive method to evaluate piriform fossae. If piriform fossae lesions were suspected on conventional CT, VMCT should be performed. (author)

    goal of allowing the execution of the experiment's software on different operating systems in an easy way for the users. To achieve this it makes use of Virtual Machine images consisting of a JEOS (Just Enough Operational System) Linux image, bundled with CVMFS, a distributed file system for software. This image can this be run with a proper virtualizer on most of the platforms available. It also aggressively caches data on the local user's machine so that it can operate disconnected from the network. CMS wanted to compare the performance of the CMS Software running in the virtualized environment with the same software running on a native Linux box. To answer this need a series of tests were made on a controlled environment during 2010-2011. This work presents the results of those tests.

    Here, we report some electrophysiologic and imaging effects of the transcranial direct current stimulation (tDCS) over the dorsolateral prefrontal cortex (dlPFC) in drug addiction, notably in alcohol and crack-cocaine dependence. The low resolution electromagnetic tomography (LORETA) analysis obtained through event-related potentials (ERPs) under drug-related cues, more specifically in its P3 segment (300-500 ms) in both, alcoholics and crack-cocaine users, showed that the ventral medial prefrontal cortex (vmPFC) was the brain area with the largest change towards increasing activation under drug-related cues in those subjects that kept abstinence during and after the treatment with bilateral tDCS (2 mA, 35 cm(2), cathodal left and anodal right) over dlPFC, applied repetitively (five daily sessions). In an additional study in crack-cocaine, which showed craving decreases after repetitive bilateral tDCS, we examined data originating from diffusion tensor imaging (DTI), and we found increased DTI parameters in the left connection between vmPFC and nucleus accumbens (NAcc), such as the number of voxels, fractional anisotropy (FA) and apparent diffusion coefficient (ADC), in tDCS-treated crack-cocaine users when compared to the sham-tDCS group. This increasing of DTI parameters was significantly correlated with craving decreasing after the repetitive tDCS. The vmPFC relates to the control of drug seeking, possibly by extinguishing this behavior. In our studies, the bilateral dlPFC tDCS reduced relapses and craving to the drug use, and increased the vmPFC activation under drug cues, which may be of a great importance in the control of drug use in drug addiction.

    Full Text Available The paper underneath deals with image processing of color images using DSP processor (Texas Instrument product, TMS3206713. The basic process involve is to take input, a color image which is to be enhanced in DSP board and output its enhanced form which can be displayed on VM3224K2 Daughter kit (LCD. VM3224Daughter Kit is embedded with DSK6713 Kit just to display the respective images. Enhancement of color images can be carried out either in spatial domain or frequency domain. Enhancing color images in frequency domain is advantageous because individual color/frequency components can be modulated as per the requirement. Color images are analyzed into its constituent intensity and color components. Suitable scaling factor are employed for different components so that over all image is enhanced. Color images mostly uses JPEG compression format for saving bandwidth and memory space which uses popular discrete cosine transform (DCT. Hence it becomes necessary to investigate and propose new enhancement technique for the color image enhancement in compressed domain. In order to observe the colorfulness of the image, colorfulness metrics is adopted after enhancing the color image in compressed domain. The enhancement technique & proposed algorithm were well implemented practically on our hardware (TMS6713 kit. Implementation of algorithm& all computation of the paper is carried out in C-programming language.

    OBJECTIVE To investigate the relationship between vascular epithelial growth factor (VEGF) and cyclooxygenase-2 (COX-2) in melanomas and the expressive difference of VEGF and COX-2 between melanomas with and without vasculogenic mimicry(VM).METHODS Sixty cases of malignant melanomas emoeaaea In paraffin were studied. The tumors were divided into a high-grade malignant group and a low-grade malignant group based on their tumor type, atypia and survival time of the patient. Then tissue microarrays were produced from these paraffin-embedded tumor tissues which were stained for VEGF, COX-2 and PAS. The difference in expression between VEGF and COX-2 in the malignant melanomas was compared using a grid-count. In addition, the tumors were also divided into mimicry and non-mimicry groups based on their PAS staining. Then the differences between the PAS positive and negative areas of the 2 groups were compared.RESULTS In malignant melanomas with VM, VEGF and COX-2 expression was less in tumors in which VM was absent, but VEGF, COX-2 expression in high-grade malignant melanomas was higher than that in low-grade grade malignant melanomas. Expression of VEGF was correlated with COX-2 expression.CONCLUSION VM exists in some high-grade malignant melanomas. The differences and relations between VEGF and COX-2 showed that some high-grade malignant melanomas possess a unique molecular-mechanism of tumor metastasis and blood supply.

    FermiCloud is a private cloud developed in Fermi National Accelerator Laboratory to provide elastic and on-demand resources for different scientific research experiments. The design goal of the FermiCloud is to automatically allocate resources for different scientific applications so that the QoS required by these applications is met and the operational cost of the FermiCloud is minimized. Our earlier research shows that VM launching overhead has large variations. If such variations are not taken into consideration when making resource allocation decisions, it may lead to poor performance and resource waste. In this paper, we show how we may use an VM launching overhead reference model to minimize VM launching overhead. In particular, we first present a training algorithm that automatically tunes a given refer- ence model to accurately reflect FermiCloud environment. Based on the tuned reference model for virtual machine launching overhead, we develop an overhead-aware-best-fit resource allocation algorithm that decides where and when to allocate resources so that the average virtual machine launching overhead is minimized. The experimental results indicate that the developed overhead-aware-best-fit resource allocation algorithm can significantly improved the VM launching time when large number of VMs are simultaneously launched.

    2017-01-01

    3D-e-Chem-VM is an open source, freely available Virtual Machine (http://3d-e-chem.github.io/3D-e-Chem-VM/) that integrates cheminformatics and bioinformatics tools for the analysis of protein–ligand interaction data. 3D-e-Chem-VM consists of software libraries, and database and workflow tools that can analyze and combine small molecule and protein structural information in a graphical programming environment. New chemical and biological data analytics tools and workflows have been developed for the efficient exploitation of structural and pharmacological protein–ligand interaction data from proteomewide databases (e.g., ChEMBLdb and PDB), as well as customized information systems focused on, e.g., G protein-coupled receptors (GPCRdb) and protein kinases (KLIFS). The integrated structural cheminformatics research infrastructure compiled in the 3D-e-Chem-VM enables the design of new approaches in virtual ligand screening (Chemdb4VS), ligand-based metabolism prediction (SyGMa), and structure-based protein binding site comparison and bioisosteric replacement for ligand design (KRIPOdb).

    2010-01-01

    We consider an extension of the {\\em popular matching} problem in this paper. The input to the popular matching problem is a bipartite graph G = (A U B,E), where A is a set of people, B is a set of items, and each person a belonging to A ranks a subset of items in an order of preference, with ties allowed. The popular matching problem seeks to compute a matching M* between people and items such that there is no matching M where more people are happier with M than with M*. Such a matching M* is called a popular matching. However, there are simple instances where no popular matching exists. Here we consider the following natural extension to the above problem: associated with each item b belonging to B is a non-negative price cost(b), that is, for any item b, new copies of b can be added to the input graph by paying an amount of cost(b) per copy. When G does not admit a popular matching, the problem is to "augment" G at minimum cost such that the new graph admits a popular matching. We show that this problem is...

    The Vuilleumier (VM) refrigerator, known as heat driven refrigerator, is one kind of closed-cycle Stirling type regenerative refrigerator. The VM refrigerator with power being supplied by liquid nitrogen was proposed by Hogen and developed by Zhou, which shows great potential for development below 10 K. This paper describes the experimental development of a VM cryocooler operating below 8 K, which was achieved by using liquid nitrogen as a heat sink of middle cavity. The regenerator was optimized by using a part of metallic magnetic regenerator material Er3Ni to replace the lead sphere and a no-load temperature of 7.8 K was obtained. Then all the lead spheres were replaced by Er0.6Pr0.4 material and a no-load temperature of 7.35 K was obtained, which is the lowest temperature for this kind of refrigerator reported so far. The cooling power at 10 K is about 500 mW with a pressure ratio near 1.6 and a charge pressure of 1.8 MPa. Especially, the magnetic material Er0.6Pr0.4 was found to be a potential substitution for the conventional lead.

    This paper presents experimental results on a novel two-stage gas-coupled VM-PT cryocooler, which is a one-stage VM cooler coupled a pulse tube cooler. In order to reach temperatures below the critical point of helium-4, a one-stage coaxial pulse tube cryocooler was gas-coupled on the cold end of the former VM cryocooler. The low temperature inertance tube and room temperature gas reservoir were used as phase shifters. The influence of room temperature double-inlet was first investigated, and the results showed that it added excessive heat loss. Then the inertance tube, regenerator and the length of the pulse tube were researched experimentally. Especially, the DC flow, whose function is similar to the double-orifice, was experimentally studied, and shown to contribute about 0.2 K for the no-load temperature. The minimum no-load temperature of 4.4 K was obtained with a pressure ratio near 1.5, working frequency of 2.2 Hz, and average pressure of 1.73 MPa.

  11. Energy Efficient Security Preserving VM Live Migration In Data Centers For Cloud Computing

    2012-03-01

    Full Text Available Virtualization is an innovation that has widely been utilized in modern data centers for cloud computing to realize energy-efficient operations of servers. Virtual machine (VM migration brings multiple benefits such as resource distribution and energy aware consolidation. Server consolidation achieves energy efficiency by enabling multiple instances of operating systems to run simultaneously on a single machine. With virtualization, it is possible to consolidate severs through VM live migration. However, migration of virtual machines brings extra energy consumption and serious security concerns that derail full adoption of this technology. In this paper, we propose a secure energy-aware provisioning of cloud computing resources on consolidated and virtualized platforms. Energy efficiency is achieved through just-right dynamic Round-Robin provisioning mechanism and the ability to power down sub-systems of a host system that are not required by VMs mapped to it. We further propose solutions to security challenges faced during VM live migration. We validate our approach by conducting a set of rigorous performance evaluation study using CloudSim toolkit. The experimental results show that our approach achieves reduced energy consumption in data centers while not compromising on security.

  12. Teaching Japanese Popular Culture

    Full Text Available Japanese popular culture has arrived on American college campuses as never before. Student interest in Japanese manga (comic books, anime (animated films and television shows, and video games drives much of the enrollment in Japanese courses and Japanese majors and minors. In response to student interest, as well as the establishment of popular culture as a topic of serious academic scholarship, the demand for courses on Japanese popular culture has never been higher. Yet the number of scholars specializing in the study of popular culture is still relatively small. This can potentially create problems, as faculty teach outside their expertise, and perhaps face an uncomfortable situation in which the students know more about the topic than the professor. In this article, I will offer some suggestions and advice for faculty creating a popular culture course for the first time, based on my experiences teaching undergraduates at the University of Notre Dame. The course I developed reflects my background in Japanese literature and film, and is but one example of many possible approaches to the topic. The sample syllabus and list of resources at the end of this article provide citations for all text and media sources mentioned.

  13. Determinants of Meme Popularity

    CERN Document Server

    Gleeson, James P; Baños, Raquel A; Moreno, Yamir

    2015-01-01

    Online social media have greatly affected the way in which we communicate with each other. However, little is known about what are the fundamental mechanisms driving dynamical information flow in online social systems. Here, we introduce a generative model for online sharing behavior and analytically show, using techniques from mathematical population genetics, that competition between memes for the limited resource of user attention leads to a type of self-organized criticality, with heavy-tailed distributions of meme popularity: a few memes "go viral" but the majority become only moderately popular. The time-dependent solutions of the model are shown to fit empirical micro-blogging data on hashtag usage, and to predict novel scaling features of the data. The presented framework, in contrast to purely empirical studies or simulation-based models, clearly distinguishes the roles of two distinct factors affecting meme popularity: the memory time of users and the connectivity structure of the social network.

  18. An assessment of the ICE6G_C(VM5a) glacial isostatic adjustment model

    Purcell, A.; Tregoning, P.; Dehecq, A.

    2016-05-01

    The recent release of the next-generation global ice history model, ICE6G_C(VM5a), is likely to be of interest to a wide range of disciplines including oceanography (sea level studies), space gravity (mass balance studies), glaciology, and, of course, geodynamics (Earth rheology studies). In this paper we make an assessment of some aspects of the ICE6G_C(VM5a) model and show that the published present-day radial uplift rates are too high along the eastern side of the Antarctic Peninsula (by ˜8.6 mm/yr) and beneath the Ross Ice Shelf (by ˜5 mm/yr). Furthermore, the published spherical harmonic coefficients—which are meant to represent the dimensionless present-day changes due to glacial isostatic adjustment (GIA)—contain excessive power for degree ≥90, do not agree with physical expectations and do not represent accurately the ICE6G_C(VM5a) model. We show that the excessive power in the high-degree terms produces erroneous uplift rates when the empirical relationship of Purcell et al. (2011) is applied, but when correct Stokes coefficients are used, the empirical relationship produces excellent agreement with the fully rigorous computation of the radial velocity field, subject to the caveats first noted by Purcell et al. (2011). Using the Australian National University (ANU) groups CALSEA software package, we recompute the present-day GIA signal for the ice thickness history and Earth rheology used by Peltier et al. (2015) and provide dimensionless Stokes coefficients that can be used to correct satellite altimetry observations for GIA over oceans and by the space gravity community to separate GIA and present-day mass balance change signals. We denote the new data sets as ICE6G_ANU.

  19. Sound as Popular Culture

    DEFF Research Database (Denmark)

    The wide-ranging texts in this book take as their premise the idea that sound is a subject through which popular culture can be analyzed in an innovative way. From an infant’s gurgles over a baby monitor to the roar of the crowd in a stadium to the sub-bass frequencies produced by sound systems...... in the disco era, sound—not necessarily aestheticized as music—is inextricably part of the many domains of popular culture. Expanding the view taken by many scholars of cultural studies, the contributors consider cultural practices concerning sound not merely as semiotic or signifying processes but as material......, physical, perceptual, and sensory processes that integrate a multitude of cultural traditions and forms of knowledge. The chapters discuss conceptual issues as well as terminologies and research methods; analyze historical and contemporary case studies of listening in various sound cultures; and consider...

  20. Elites and popular nationalism.

    Whitmeyer, Joseph M

    2002-09-01

    Much current theory concerning nationalism holds that elites commonly create or cause popular nationalism. In part, that thesis may be due to an overwhelming emphasis in research on nationalism on positive cases: cases where nationalism has appeared, ignoring cases where it has not. In this article, I challenge the thesis by showing numerous historical cases in which elites have promoted nationalisms that ordinary people have not adopted, or in which ordinary people have adopted a nationalism before it was taken up by elites. Even if elites do not create popular nationalism, however, they can and do shape its expression in a variety of ways, such as organizing it, providing relevant information, or providing opportunity or incentive for it. I show this through historical examples.

    CernVM-FS recently added the possibility of using plugin for cache management. In order to investigate the capabilities and limits of such possibility, an XRootD plugin was written and benchmarked; as a byproduct, a POSIX plugin was also generated. The tests revealed that the plugin interface introduces no signicant performance over- head; moreover, the XRootD plugin performance was discovered to be worse than the ones of the built-in cache manager and the POSIX plugin. Further test of the XRootD component revealed that its per- formance is dependent on the server disk speed.

    2015-01-01

    Tree-based overlay multicast is an effective group communication method for media streaming applications. However, a group member's departure causes all of its descendants to be disconnected from the multicast tree for some time, which results in poor performance. The above problem is difficult to be addressed because overlay multicast tree is intrinsically instable. In this paper, we proposed a novel stability enhancing solution, VMCast, for tree-based overlay multicast. This solution uses two types of on-demand cloud virtual machines (VMs), i.e., multicast VMs (MVMs) and compensation VMs (CVMs). MVMs are used to disseminate the multicast data, whereas CVMs are used to offer streaming compensation. The used VMs in the same cloud datacenter constitute a VM cluster. Each VM cluster is responsible for a service domain (VMSD), and each group member belongs to a specific VMSD. The data source delivers the multicast data to MVMs through a reliable path, and MVMs further disseminate the data to group members along domain overlay multicast trees. The above approach structurally improves the stability of the overlay multicast tree. We further utilized CVM-based streaming compensation to enhance the stability of the data distribution in the VMSDs. VMCast can be used as an extension to existing tree-based overlay multicast solutions, to provide better services for media streaming applications. We applied VMCast to two application instances (i.e., HMTP and HCcast). The results show that it can obviously enhance the stability of the data distribution.

  10. Workload-Aware and CPU Frequency Scaling for Optimal Energy Consumption in VM Allocation

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available In the problem of VMs consolidation for cloud energy saving, different workloads will ask for different resources. Thus, considering workload characteristic, the VM placement solution will be more reasonable. In the real world, different workload works in a varied CPU utilization during its work time according to its task characteristics. That means energy consumption related to both the CPU utilization and CPU frequency. Therefore, only using the model of CPU frequency to evaluate energy consumption is insufficient. This paper theoretically verified that there will be a CPU frequency best suit for a certain CPU utilization in order to obtain the minimum energy consumption. According to this deduction, we put forward a heuristic CPU frequency scaling algorithm VP-FS (virtual machine placement with frequency scaling. In order to carry the experiments, we realized three typical greedy algorithms for VMs placement and simulate three groups of VM tasks. Our efforts show that different workloads will affect VMs allocation results. Each group of workload has its most suitable algorithm when considering the minimum used physical machines. And because of the CPU frequency scaling, VP-FS has the best results on the total energy consumption compared with the other three algorithms under any of the three groups of workloads.

    Can popular astrophotography stimulate real astronomical discovery? Perhaps surprisingly, in some cases, the answer is yes. Several examples are given using the Astronomy Picture of the Day (APOD) site as an example venue. One reason is angular -- popular wide and deep images sometimes complement professional images which typically span a more narrow field. Another reason is temporal -- an amateur is at the right place and time to take a unique and illuminating image. Additionally, popular venues can be informational -- alerting professionals to cutting-edge amateur astrophotography about which they might not have known previously. Methods of further encouraging this unusual brand of citizen science are considered.

    Energy demand and consumption in buildings will rise rapidly in the near future because of several social economics factors and this situation occurs not only in developed countries but also in developing countries such as Malaysia. There is demand towards building with energy efficiency features at this time, however most of the current buildings types are still being constructed with conventional designs, thus contribute to inefficient of energy consumption during the operation stage of the building. This paper presents the concept and the application of Value Management (VM) approach and its potential to improve consideration of energy efficiency within pre-construction process. Based on the relevant literatures, VM has provides an efficient and effective delivery system to fulfill the objectives and client's requirements. Generally in this paper, VM is discussed and scrutinized with reference to previous studies to see how these concepts contribute to better optimize the energy consumption in a building by seeking the best value energy efficiency through the design and construction process. This paper will not draw any conclusion but rather a preliminary research to propose the most energy efficiency measures to reliably accomplish a function that will meet the client's needs, desires and expectations. For further research in future, simple quantitative industry survey and VM workshops will be conducted to validate and further improve the research.

    19 patients with advanced ovarian cancer (FIGO-stages IIb-IV) were treated by ultra-high doses of VM26 partly according to positive oncobiograms during Multiple-drug-stoss-therapy. The toxic reactions and the cytostatic effect were investigated. The range of 57,9% remissions and the moderate toxicity suggest a specific application of VM26 in advanced ovarian cancer.

  1. The Branding Potential And Japanese Popular Culture Overseas

    Full Text Available There has been a surge in the interest in Japanese popular culture worldwide. The objective of this paper was to explore the extent to which products, images, and activities associated with Japanese popular culture are achieving the status of recognizable and sustainable consumer brands overseas.  A specially designed survey was used to examine the levels of awareness, interest, and participation in Japanese popular cultural activities of individuals from different national backgrounds. Regression analysis and other statistical techniques were used to evaluate the empirical findings. The results strongly supported the view that Japanese popular culture products and services have tremendous branding potential overseas.  By breaking down popular culture into recognizable components, it was possible to explore the underlying branding potential trends and gain insights into areas for further market development. This approach can be generally applied to the study of the development and marketing of popular culture products & services.

  2. Advanced neuroblastoma: improved response rate using a multiagent regimen (OPEC) including sequential cisplatin and VM-26.

    1984-07-01

    Forty-two children, all over one year of age, were given vincristine, cyclophosphamide, and sequentially timed cisplatin and VM-26 (OPEC) or OPEC and doxorubicin (OPEC-D) as initial treatment for newly diagnosed stage III or IV neuroblastoma. Good partial response was achieved in 31 patients (74%) overall and in 28 (78%) of 36 patients whose treatment adhered to the chemotherapy protocol, compared with a 65% response rate achieved in a previous series of children treated with pulsed cyclophosphamide and vincristine with or without doxorubicin. Only six patients, including two of the six children whose treatment did not adhere to protocol, failed to respond, but there were five early deaths from treatment-related complications. Tumor response to OPEC, which was the less toxic of the two regimens, was at least as good as tumor response to OPEC-D. Cisplatin-induced morbidity was clinically significant in only one patient and was avoided in others by careful monitoring of glomerular filtration rate and hearing. Other centers should test the efficacy of OPEC or equivalent regimens in the treatment of advanced neuroblastoma.

  3. Optimal bandwidth-aware VM allocation for Infrastructure-as-a-Service

    CERN Document Server

    Dutta, Debojyoti; Post, Ian; Shinde, Rajendra

    2012-01-01

    Infrastructure-as-a-Service (IaaS) providers need to offer richer services to be competitive while optimizing their resource usage to keep costs down. Richer service offerings include new resource request models involving bandwidth guarantees between virtual machines (VMs). Thus we consider the following problem: given a VM request graph (where nodes are VMs and edges represent virtual network connectivity between the VMs) and a real data center topology, find an allocation of VMs to servers that satisfies the bandwidth guarantees for every virtual network edge---which maps to a path in the physical network---and minimizes congestion of the network. Previous work has shown that for arbitrary networks and requests, finding the optimal embedding satisfying bandwidth requests is $\\mathcal{NP}$-hard. However, in most data center architectures, the routing protocols employed are based on a spanning tree of the physical network. In this paper, we prove that the problem remains $\\mathcal{NP}$-hard even when the phys...

    The eXplore CT 120 is the latest generation micro-CT from General Electric. It is equipped with a high-power tube and a flat-panel detector. It allows high resolution and high contrast fast CT scanning of small animals. The aim of this study was to compare the performance of the eXplore CT 120 with that of the eXplore Ultra, its predecessor for which the methodology using the vmCT phantom has already been described . The phantom was imaged using typical a rat (fast scan or F) or mouse (in vivo bone scan or H) scanning protocols. With the slanted edge method, a 10% modulation transfer function (MTF) was observed at 4.4 (F) and 3.9-4.4 (H) mm{sup -1} corresponding to 114 {mu}m resolution. A fairly larger MTF was obtained by the coil method with the MTF for the thinnest coil (3.3 mm{sup -1}) equal to 0.32 (F) and 0.34 (H). The geometric accuracy was better than 0.3%. There was a highly linear (R{sup 2}>0.999) relationship between measured and expected CT numbers for both the CT number accuracy and linearity sections of the phantom. A cupping effect was clearly seen on the uniform slices and the uniformity-to-noise ratio ranged from 0.52 (F) to 0.89 (H). The air CT number depended on the amount of polycarbonate surrounding the area where it was measured; a difference as high as approximately 200 HU was observed. This hindered the calibration of this scanner in HU. This is likely due to the absence of corrections for beam hardening and scatter in the reconstruction software. However in view of the high linearity of the system, the implementation of these corrections would allow a good quality calibration of the scanner in HU. In conclusion, the eXplore CT 120 achieved a better spatial resolution than the eXplore Ultra (based on previously reported specifications) and future software developments will include beam hardening and scatter corrections that will make the new generation CT scanner even more promising.

  9. Not your ordinary librarian debunking the popular perceptions of librarians

    2012-01-01

    When you picture a librarian, what do you imagine? An old white woman with glasses and a prudish disposition? That is the image that many people conjure up when asked to picture a librarian; with 82 per cent of the professional force being female and the average age of a librarian at 45, coupled with popular stereotypical images, it is difficult to dispute the perceptions. But there is more to librarians than meets the eye. This book will explore the origin of the image and popular media images of the librarian, in addition to the effects of the stereotype, and the challenges to the perception

  10. Space-geodetic and water level gauge constraints on continental uplift and tilting over North America: regional convergence of the ICE-6G_C (VM5a/VM6) models

    Roy, Keven; Peltier, W. R.

    2017-08-01

    We present a series of analyses of the regional convergence of the iterative methodology that has been developed for use in the construction of global models of the glacial isostatic adjustment process. Our specific focus is upon the North American component of such models which embodied the largest concentration of grounded land ice at the Last Glacial Maximum. We show that, although the introduction of the VM6 viscosity structure helps the global ICE-6G_C (VM5a) model to improve the fit to relative sea level data from the region of forebulge collapse along the U.S. East coast, it also leads to a significant misfit to the totality of the available space-geodetic observations, which the original ICE-6G_C (VM5a) model was able to fit with high accuracy. This raises the issue of the convergence of the iterative methodology being employed in the process of model construction. We demonstrate through detailed further analysis that a fully converged solution which reconciles all available data from the continent, including additional data on the time dependent de-levelling of the Great Lakes region, is obtained through modest further modifications of both the viscosity structure of the model and the North American component of the surface mass loading history.

    We fit the revised global model of glacial isostatic adjustment ICE-6G_C (VM5a) to all available data, consisting of several hundred GPS uplift rates, a similar number of 14C dated relative sea level histories, and 62 geologic estimates of changes in Antarctic ice thickness. The mantle viscosity profile, VM5a is a simple multi-layer fit to prior model VM2 of Peltier (1996, Science). However, the revised deglaciation history, ICE-6G (VM5a), differs significantly from previous models in the Toronto series. (1) In North America, GPS observations of vertical uplift of Earth's surface from the Canadian Base Network require the thickness of the Laurentide ice sheet at Last Glacial Maximum to be significantly revised. At Last Glacial Maximum the new model ICE-6G_C in this region, relative to ICE-5G, roughly 50 percent thicker east of Hudson Bay (in and northern Quebec and Labrador region) and roughly 30 percent thinner west of Hudson Bay (in Manitoba, Saskatchewan, and the Northwest Territories).the net change in mass, however, is small. We find that rates of gravity change determined by GRACE when corrected for the predictions of ICE-6G_C (VM5a) are significantly smaller than residuals determined on the basis of earlier models. (2) In Antarctica, we fit GPS uplift rates, geologic estimates of changes in ice thickness, and geologic constraints on the timing of ice loss. The resulting deglaciation history also differs significantly from prior models. The contribution of Antarctic ice loss to global sea level rise since Last Glacial Maximum in ICE-6G_C is 13.6 meters, less than in ICE-5G (17.5 m), but significantly larger than in both the W12A model of Whitehouse et al. [2012] (8 m) and the IJ05 R02 model of Ivins et al. [2013] (7.5 m). In ICE-6G_C rapid ice loss occurs in Antarctica from 11.5 to 8 thousands years ago, with a rapid onset at 11.5 ka thereby contributing significantly to Meltwater Pulse 1B. In ICE-6G_C (VM5a), viscous uplift of Antarctica is increasing

    The semisupervised least squares support vector machine (LS-S³VM) is an important enhancement of least squares support vector machines in semisupervised learning. Given that most data collected from the real world are without labels, semisupervised approaches are more applicable than standard supervised approaches. Although a few training methods for LS-S³VM exist, the problem of deriving the optimal decision hyperplane efficiently and effectually has not been solved. In this paper, a fully weighted model of LS-S³VM is proposed, and a simple integer programming (IP) model is introduced through an equivalent transformation to solve the model. Based on the distances between the unlabeled data and the decision hyperplane, a new indicator is designed to represent the possibility that the label of an unlabeled datum should be reversed in each iteration during training. Using the indicator, we construct an extended candidate set consisting of the indices of unlabeled data with high possibilities, which integrates more information from unlabeled data. Our algorithm is degenerated into a special scenario of the previous algorithm when the extended candidate set is reduced into a set with only one element. Two strategies are utilized to determine the descent directions based on the extended candidate set. Furthermore, we developed a novel method for locating a good starting point based on the properties of the equivalent IP model. Combined with the extended candidate set and the carefully computed starting point, a fast algorithm to solve LS-S³VM quasi-optimally is proposed. The choice of quasi-optimal solutions results in low computational cost and avoidance of overfitting. Experiments show that our algorithm equipped with the two designed strategies is more effective than other algorithms in at least one of the following three aspects: 1) computational complexity; 2) generalization ability; and 3) flexibility. However, our algorithm and other algorithms have similar

    Asparaginyl endopeptidase is a cysteine endopeptidase that has strict substrate specificity toward the carboxy side of asparagine residues. Vigna mungo processing enzyme 1, termed VmPE-1, occurs in the cotyledons of germinated seeds of V. mungo, and is possibly involved in the post-translational processing of a vacuolar cysteine endopeptidase, designated SH-EP, which degrades seed storage protein. VmPE-1 also showed a substrate specificity to asparagine residues, and its enzymatic activity was inhibited by NEM but not E-64. In addition, purified VmPE-1 had a potential to process the recombinant SH-EP precursor to its intermediate in vitro. cDNA clones for VmPE-1 and its homologue, named VmPE-1A, were identified and sequenced, and their expressions in the cotyledons of V. mungo seedlings and other organs were investigated. VmPE-1 mRNA and SH-EP mRNA were expressed in germinated seeds at the same stage of germination although the enzymatic activity of VmPE-1 rose prior to that of SH-EP. The level of VmPE-1A mRNA continued increasing as germination proceeded. In roots, stems and leaves of fully grown plants, and in hypocotyls, VmPE-1 and VmPE-1A were little expressed. We discuss possible functions of VmPE-1 and VmPE-1A in the cotyledons of germinated seeds.

    A common use pattern in the computing models of particle physics experiments is running many distributed applications that read from a shared set of data files. We refer to this data is auxiliary data, to distinguish it from (a) event data from the detector (which tends to be different for every job), and (b) conditions data about the detector (which tends to be the same for each job in a batch of jobs). Relatively speaking, conditions data also tends to be relatively small per job where both event data and auxiliary data are larger per job. Unlike event data, auxiliary data comes from a limited working set of shared files. Since there is spatial locality of the auxiliary data access, the use case appears to be identical to that of the CernVM- Filesystem (CVMFS). However, we show that distributing auxiliary data through CVMFS causes the existing CVMFS infrastructure to perform poorly. We utilize a CVMFS client feature called "alien cache" to cache data on existing local high-bandwidth data servers that were engineered for storing event data. This cache is shared between the worker nodes at a site and replaces caching CVMFS files on both the worker node local disks and on the site's local squids. We have tested this alien cache with the dCache NFSv4.1 interface, Lustre, and the Hadoop Distributed File System (HDFS) FUSE interface, and measured performance. In addition, we use high-bandwidth data servers at central sites to perform the CVMFS Stratum 1 function instead of the low-bandwidth web servers deployed for the CVMFS software distribution function. We have tested this using the dCache HTTP interface. As a result, we have a design for an end-to-end high-bandwidth distributed caching read-only filesystem, using existing client software already widely deployed to grid worker nodes and existing file servers already widely installed at grid sites. Files are published in a central place and are soon available on demand throughout the grid and cached locally on the

    To test the hypothesis that pleasure from artistic music is intellectual while that from popular music is physiological, this study investigated the different functional mechanisms between aesthetic appreciation of artistic and popular music using fMRI. 18 male non-musicians were scanned while they performed an aesthetic rating task for excerpts of artistic music, popular music and musical notes playing and singing (control). The rating scores of artistic and popular music excerpts were both significantly higher than that of control materials while the scores of them were not different. The fMRI results showed both artistic and popular conditions activated the VS and vmPFC, compared with control condition. When contrasted popular and artistic condition directly, we found popular music activated right putamen, while artistic music activated right mPFC. By parametric analysis, we found the activation of right putamen tracked the aesthetic ratings of popular music, whereas the BOLD signal in right mPFC tracked the aesthetic ratings of artistic music. These results indicate the reward induced by popular music is closer to a primary reward while that induced by artistic music is closer to a secondary reward. We also found artistic music activated ToM areas, including PCC/PC, arMFC and TPJ, when compared with popular music. And these areas also tracked aesthetic ratings of artistic music but not those of popular music. These results imply that the pleasure from former comes from cognitive empathy. In conclusion, this study gives clear neuronal evidences supporting the view that artistic music is of intelligence and social cognition involved while the popular music is of physiology.

    Full Text Available The author analyzes the emergence and persistence of images and stereotypes in the nineteenth century Argentine popular culture of certain occupations as typically Basque ones (e.i. the Basque milkman. The emergence of those stereotypes did not necessarily have to do with an overwhelming Basque presence in those occupations but mostly with their features and symbolic implications. For undertaking the analysis the author has mainly used the returns from the Argentine National Censuses of Population from nineteenth century.

    Se intentan dilucidar aspectos vinculados a ciertos estereotipos laborales de inmigrantes vascos en Argentina que perduran en el recuerdo popular, especialmente en lo que hace a la génesis de esas imágenes y el predominio de algunos oficios sobre otros. La conformación de los estereotipos (por ej. vasco lechero no estaría directamente vinculado a un predomino cuantitativo de los vascos en esos oficios, sino también a ciertas características y aditamentos simbólicos vinculados a ellos. Para reconstruir la génesis del recuerdo popular sobre el mundo del trabajo decimonónico, se utilizan principalmente las cédulas censales correspondientes a los Censos Nacionales de 1869 y 1895, como así también distintas fuentes literarias.

  9. Optimizing VM allocation and data placement for data-intensive applications in cloud using ACO metaheuristic algorithm

    2017-04-01

    Full Text Available Nowadays data-intensive applications for processing big data are being hosted in the cloud. Since the cloud environment provides virtualized resources for computation, and data-intensive applications require communication between the computing nodes, the placement of Virtual Machines (VMs and location of data affect the overall computation time. Majority of the research work reported in the current literature consider the selection of physical nodes for placing data and VMs as independent problems. This paper proposes an approach which considers VM placement and data placement hand in hand. The primary objective is to reduce cross network traffic and bandwidth usage, by placing required number of VMs and data in Physical Machines (PMs which are physically closer. The VM and data placement problem (referred as MinDistVMDataPlacement problem is defined in this paper and has been proved to be NP- Hard. This paper presents and evaluates a metaheuristic algorithm based on Ant Colony Optimization (ACO, which selects a set of adjacent PMs for placing data and VMs. Data is distributed in the physical storage devices of the selected PMs. According to the processing capacity of each PM, a set of VMs are placed on these PMs to process data stored in them. We use simulation to evaluate our algorithm. The results show that the proposed algorithm selects PMs in close proximity and the jobs executed in the VMs allocated by the proposed scheme outperforms other allocation schemes.

    The objective of this work is to demonstrate the gains obtained with electrical energy, due to replacement of electric cables of air called 'power of the green line to arc furnaces VM1 and panel 1 of Villares Metals - Unit Sumare' by underground cables. We can mention other gains in safety, maintenance, environment and quality of power, but will not be measured. This substitution was motivated due to the existing line to the limit of its useful life, with restrictions to increase the load (expansion) and stops unwanted maintenance. It is emphasized that this determination is the only power loss due to ohmic resistance of bare aluminum conductor used in the old line (green). The economy demonstrated in this study is R$ 3,313.21 and 16.339752 MWh even if it is significantly reduced because there is a spare in MWh, which can be used within the company in which extensions are necessary.

    Full Text Available This paper examines Dickens’s descriptions of public executions in his letters and early journalism as a context in which to read the final scene of 'A Tale of Two Cities' (1859. It argues that despite his traumatised responses to public hangings, Dickens is able to use the site of the scaffold to articulate some fundamental human fears and dispositions. The paper compares Dickens’s response to the horrors of the French Revolution with Carlyle’s, and shows throughout how Dickens firmly repudiates Trollope's somewhat rueful dismissal of him as ‘Mr Popular Sentiment’.

  16. Archaeoastronomical Concepts in Popular Culture

    Science.gov (United States)

    Krupp, Edwin C.

    Broad public embrace of archaic astronomy probably began in the eighteenth century with awareness of the summer solstice sunrise's affiliation with Stonehenge. Since that time, Stonehenge has retained an astronomical mystique that attracts crowds mobilized by the monument's supposed cosmic purpose. They are committed to witness prehistoric heritage operating in real time and with enduring function. More recently, mass media have intermittently thrown a spotlight on new archaeoastronomical discoveries. While the details, ambiguities, and nuances of disciplined study of astronomy in antiquity do not usually infiltrate popular culture, some astronomical alignments, celestial events, sky-tempered symbols, and astral narratives have become well known and referenced in popular culture. Places and relics that command public interest with astronomical connotations are transformed into cultural icons and capture visitors on a quest for the authenticity the past is believed to possess. Monuments and ideas that successfully forge a romantic bond with the past and inspire an imagined sense of sharing the experience, perspective, and wisdom of antiquity persist in the cultural landscape.

  17. Noninsect Arthropods in Popular Music

    Directory of Open Access Journals (Sweden)

    Joseph R. Coelho

    2011-05-01

    Full Text Available The occurrence of noninsect arthropods in popular music was examined in order to explore human attitudes toward these species, especially as compared to insects. Crustaceans were the most commonly referenced taxonomic group in artist names, album titles and cover art, followed by spiders and scorpions. The surprising prevalence of crustaceans may be related to the palatability of many of the species. Spiders and scorpions were primarily used for shock value, as well as totemic qualities of strength and ferocity. Spiders were the most abundant group among song titles, perhaps because of their familiarity to the general public. Three noninsect arthropod album titles were found from the early 1970s, then none appear until 1990. Older albums are difficult to find unless they are quite popular, and the resurgence of albums coincides with the rise of the internet. After 1990, issuance of such albums increased approximately linearly. Giant and chimeric album covers were the most common of themes, indicating the use of these animals to inspire fear and surprise. The lyrics of select songs are presented to illustrate the diversity of sentiments present, from camp spookiness to edibility.

    Previous studies of weather-inspired classical music showed that all forms of music (as well as visual arts and literature) reflect the significance of the environment in society. Here we quantify the extent to which weather has inspired popular musicians, and how weather is represented in English-language pop music. Our work is in press at Weather. Over 750 songs have been identified which were found to refer to meteorological phenomena, mainly in their lyrics, but also in the title of the song, name of the band or songwriter and occasionally in the song's music or sound effects. Over one third of the songs analysed referred to either sun or rain, out of a possible 20 weather categories. It was found that artists use weather to describe emotion, for example, to mirror the changes in a relationship. In this context, rain was broadly seen negatively, and might be used to signify the end of a relationship. Rain could also be perceived in a positive way, such as in songs from more agricultural communities. Wind was the next most common weather phenomenon, but did not represent emotions as much as sun or rain. However, it was the most frequently represented weather type in the music itself, such as in instrumental effects, or non-verbally in choruses. From the limited evidence available, we found that artists were often inspired by a single weather event in writing lyrics, whereas the outcomes were less clearly identifiable from longer periods of good or bad weather. Some artists were influenced more by their environment than others, but they were often inspired to write many songs about their surroundings as part of every-day life, rather than weather in particular. Popular singers and songwriters can therefore emotionally connect their listeners to the environment; this could be exploited to communicate environmental science to a broad audience.

    Yu, Bei; Chen, Miao; Kwok, Linchi

    Popularity of social marketing messages indicates the effectiveness of the corresponding marketing strategies. This research aims to discover the characteristics of social marketing messages that contribute to different level of popularity. Using messages posted by a sample of restaurants on Facebook as a case study, we measured the message popularity by the number of "likes" voted by fans, and examined the relationship between the message popularity and two properties of the messages: (1) content, and (2) media type. Combining a number of text mining and statistics methods, we have discovered some interesting patterns correlated to "more popular" and "less popular" social marketing messages. This work lays foundation for building computational models to predict the popularity of social marketing messages in the future.

    Online popularity has a major impact on videos, music, news and other contexts in online systems. Characterizing online popularity dynamics is nature to explain the observed properties in terms of the already acquired popularity of each individual. In this paper, we provide a quantitative, large scale, temporal analysis of the popularity dynamics in two online video-provided websites, namely MovieLens and Netflix. The two collected data sets contain over 100 million records and even span a decade. We characterize that the popularity dynamics of online videos evolve over time, and find that the dynamics of the online video popularity can be characterized by the burst behaviors, typically occurring in the early life span of a video, and later restricting to the classic preferential popularity increase mechanism.

Adbusters is an organization which performs “Culture Jamming”; a rebellious act reacting towards commercialism domination in many aspects including popular culture. Compared to other similar organizations, Adbusters has been executing more various activisms using several media which other organizations do not use. This study used the Adbusters’ official website and blogs as main data sources. The data of Adbusters’ activities and media usage were categorized and analyzed, thus the tendency of its development can be described. This study also analyzed Adbusters’ activity using Media Hegemony Theory and Political Economy Media Theory. The media has been dominated by a certain group that owns politic and economic power, so the information flow has been dominated by them. Media and its contents have been commercialized, thus capitalism and commercialism have been considered as a common system that should run the world. Adbusters has been trying to stop the domination and change the society’s way of thinking into a more critical way of thinking.   Abstrak: Studi literatur ini meneliti tentang Adbusters, sebuah organisasi anti komersial, dengan mendeskripsikan aktivitas serta penggunaan media organisasi tersebut dari tahun 2007-2010 dalam mengkritisi budaya populer.

    The Warburg effect and tumor hypoxia underlie a unique cancer metabolic phenotype characterized by glucose dependency and aerobic fermentation. We previously showed that two non-toxic metabolic therapies - the ketogenic diet with concurrent hyperbaric oxygen (KD+HBOT) and dietary ketone supplementation - could increase survival time in the VM-M3 mouse model of metastatic cancer. We hypothesized that combining these therapies could provide an even greater therapeutic benefit in this model. Mice receiving the combination therapy demonstrated a marked reduction in tumor growth rate and metastatic spread, and lived twice as long as control animals. To further understand the effects of these metabolic therapies, we characterized the effects of high glucose (control), low glucose (LG), ketone supplementation (βHB), hyperbaric oxygen (HBOT), or combination therapy (LG+βHB+HBOT) on VM-M3 cells. Individually and combined, these metabolic therapies significantly decreased VM-M3 cell proliferation and viability. HBOT, alone or in combination with LG and βHB, increased ROS production in VM-M3 cells. This study strongly supports further investigation into this metabolic therapy as a potential non-toxic treatment for late-stage metastatic cancers.

    2013-03-01

    In addition to classical bovine spongiform encephalopathy (C-BSE), which is recognized as being at the origin of the human variant form of Creutzfeldt-Jakob disease, 2 rare phenotypes of BSE (H-type BSE [H-BSE] and L-type BSE [L-BSE]) were identified in 2004. H-type BSE and L-BSE are considered to be sporadic forms of prion disease in cattle because they differ from C-BSE with respect to incubation period, vacuolar pathology in the brain, and biochemical properties of the protease-resistant prion protein (PrP) in natural hosts and in some mouse models that have been tested. Recently, we showed that H-BSE transmitted to C57Bl/6 mice resulted in a dissociation of the phenotypic features, that is, some mice showed an H-BSE phenotype, whereas others had a C-BSE phenotype. Here, these 2 phenotypes were further studied in VM mice and compared with cattle C-BSE, H-BSE, and L-BSE. Serial passages from the C-BSE-like phenotype on VM mice retained similarities with C-BSE. Moreover, our results indicate that strains 301V and 301C derived from C-BSE transmitted to VM and C57Bl/6 mice, respectively, are fundamentally the same strain. These VM transmission studies confirm the unique properties of the C-BSE strain and support the emergence of a strain that resembles C-BSE from H-BSE.

Individually and combined, these metabolic therapies significantly decreased VM-M3 cell proliferation and viability. HBOT, alone or in combination with LG and βHB, increased ROS production in VM-M3 cells. This study strongly supports further investigation into this metabolic therapy as a potential non-toxic treatment for late-stage metastatic cancers.

    Full Text Available This article focuses on the Brazilian university crisis and its alternative for change and innovation, at the curricula and at the institutional level. It points out the university capacity to take into account critical contexts, developing political and epistemological actions in order to struggle with social problems. In its struggle, university is shown as responsible of the solutions of humans are exposed by their social and political contexts. Brazilian university has gotten the legacy from European corporative model and also from American technocratic idiosyncrasy. The Southern Frontier Federal University (UFFS is one of the new federal universities created by the government into the National Program for Education (2000-2010 in order to extend the range of access to public higher education along the country. Thus, this university tries to solve some of the historical educational problems of Brazilian education.

    Healthcare systems are organized following one of two basic models: social security systems, which link access to health services to labor status, and national health systems, which grant access to health as a citizen's right. Mexico adopted, since the institutionalization of social security and healthcare services in 1943, a mixed system. Social security institutions covered the salaried workers and public assistance was granted to the remaining of the population. At the beginning of the XXI century the Mexican health system entered a crisis as the conditions to expand health coverage through social security were not met and public assistance services were insufficient. In order to address these developments, the Healthcare Social Protection System was founded (2004) as a mechanism to effectively guarantee every person's right to health as established after the constitutional amendment of article fourth in 1983. Seguro Popular is the mechanism that through federal and states' contributions seeks to financially protect the population without access to social security's health services, and thus prevent impoverishment due to out of pocket and catastrophic health expenditures.

The main hypothesis of the article holds that the neo-developmentalist model adopted by the government has given way to new forms of social conflict. On the one hand, the nature of this social conflict is marked by the overwhelming popularity of the government. On the other hand however, the anti-mining movement has been weakened by problems related to its organisation, leadership and strategies, which have, in turn, prevented its consolidation.

  1. Altered catalytic activity of and DNA cleavage by DNA topoisomerase II from human leukemic cells selected for resistance to VM-26.

    The simultaneous development of resistance to the cytotoxic effects of several classes of natural product anticancer drugs, after exposure to only one of these agents, is referred to as multiple drug resistance (MDR). At least two distinct mechanisms for MDR have been postulated: that associated with P-glycoprotein and that thought to be due to an alteration in DNA topoisomerase II activity (at-MDR). We describe studies with two sublines of human leukemic CCRF-CEM cells approximately 50-fold resistant (CEM/VM-1) and approximately 140-fold resistant (CEM/VM-1-5) to VM-26, a drug known to interfere with DNA topoisomerase II activity. Each of these lines is cross-resistant to other drugs known to affect topoisomerase II but not cross-resistant to vinblastine, an inhibitor of mitotic spindle formation. We found little difference in the amount of immunoreactive DNA topoisomerase II in 1.0 M NaCl nuclear extracts of the two resistant and parental cell lines. However, topoisomerase II in nuclear extracts of the resistant sublines is altered in both catalytic activity (unknotting) of and DNA cleavage by this enzyme. Also, the rate at which catenation occurs is 20-30-fold slower with the CEM/VM-1-5 preparations. The effect of VM-26 on both strand passing and DNA cleavage is inversely related to the degree of primary resistance of each cell line. Our data support the hypothesis that at-MDR is due to an alteration in topoisomerase II or in a factor modulating its activity.

    Full Text Available In order to improve the host energy efficiency in IaaS, we proposed an adaptive host resource provisioning method, CoST, which is based on QoS differentiation and VM resizing. The control model can adaptively adjust control parameters according to real time application performance, in order to cope with changes in load. CoST takes advantage of the fact that different types of applications have different sensitivity degrees to performance and cost. It places two different types of VMs on the same host and dynamically adjusts their sizes based on the load forecasting and QoS feedback. It not only guarantees the performance defined in SLA, but also keeps the host running in energy-efficient state. Real Google cluster trace and host power data are used to evaluate the proposed method. Experimental results show that CoST can provide performance-sensitive application with a steady QoS and simultaneously speed up the overall processing of performance-tolerant application by 20~66%. The host energy efficiency is significantly improved by 7~23%.

    PROOF, the Parallel ROOT Facility, is a ROOT-based framework which enables interactive parallelism for event-based tasks on a cluster of computing nodes. Although PROOF can be used simply from within a ROOT session with no additional requirements, deploying and configuring a PROOF cluster used to be not as straightforward. Recently great efforts have been spent to make the provisioning of generic PROOF analysis facilities with zero configuration, with the added advantages of positively affecting both stability and scalability, making the deployment operations feasible even for the end user. Since a growing amount of large-scale computing resources are nowadays made available by Cloud providers in a virtualized form, we have developed the Virtual PROOF-based Analysis Facility: a cluster appliance combining the solid CernVM ecosystem and PoD (PROOF on Demand), ready to be deployed on the Cloud and leveraging some peculiar Cloud features such as elasticity.

We recommended measures to improve the accuracy and quality of manufacturing of complex and large workpieces weighing up to 100 tons. To date, the technical level of many economy sectors is largely determined by the level of the production means. Based on the engineering development there is an overall automation and mechanization of production and industry processes, construction, agriculture, transport and other industries. We analyzed forms of slide sections, of errors affecting the accuracy of the workpieces manufacturing. We made simulation of the cutting forces and sliders deformations. Solved measures increase manufacturing accuracy based on multi-purpose machine tool systems of VM series. We held the analysis of the dependence of cutting forces, a slider form on its strain in different types of processing. We obtained a graph of cutting force and precision manufacturing. We defined the optimal shape of the slider cross section to increase the rigidity and reduce the slide deformation in metal cutting

  8. Yugoslav Naive Art and Popular Culture

    Directory of Open Access Journals (Sweden)

    2009-12-01

    After the Second World War, the Yugoslav socialist state also strove to equalize and democratize society through art by minimizing the differences between the producers and consumers of art. Such a policy led to the decentralization of culture by forming various cultural and artistic institutions and by holding cultural events and spectacles in the countryside and peripheral areas. Through these various informal ideological mechanisms, the state apparatus exercised its authority in socializing its people in the spirit of Yugoslav socialist self-management and the ideology of brotherhood and unity by joining together the producers and consumers of naive art from various ethnicities, cultures, and social classes. Unfortunately this transformed naive art at its peak of popularity into a decorative and souvenir artifact with a pastoral image and folklore motifs. The encouragement from the authorities on the one hand and the market on the other produced and reproduced simple art forms and narrative contents without a complex iconography, which were consumed uncritically and on a large scale. Consequently, this completely denied the core of naive art and resulted in its final devaluation.

  9. The evolution of pace in popular movies.

    Cutting, James E

    2016-01-01

    Movies have changed dramatically over the last 100 years. Several of these changes in popular English-language filmmaking practice are reflected in patterns of film style as distributed over the length of movies. In particular, arrangements of shot durations, motion, and luminance have altered and come to reflect aspects of the narrative form. Narrative form, on the other hand, appears to have been relatively unchanged over that time and is often characterized as having four more or less equal duration parts, sometimes called acts - setup, complication, development, and climax. The altered patterns in film style found here affect a movie's pace: increasing shot durations and decreasing motion in the setup, darkening across the complication and development followed by brightening across the climax, decreasing shot durations and increasing motion during the first part of the climax followed by increasing shot durations and decreasing motion at the end of the climax. Decreasing shot durations mean more cuts; more cuts mean potentially more saccades that drive attention; more motion also captures attention; and brighter and darker images are associated with positive and negative emotions. Coupled with narrative form, all of these may serve to increase the engagement of the movie viewer.

    Much can be learned about the contemporary stereotypes associated with epilepsy by studying the representation of the disorder in paintings, literature, and movies. Popular music is arguably the most accessible and ubiquitous of the creative art forms, touching most of us on a daily basis. Reviewed here are the ways in which epilepsy and seizures are used in the lyrics of musicians from a wide variety of musical genres, from hip-hop to rhythm and blues. Many of the ancient associations of epilepsy with madness, horror, and lunacy can be found in these lyrics. However, the language of epilepsy has also been appropriated by some musical artists to represent a state of sexual ecstasy and dance euphoria. The references to these states as "epilepsy" or a "seizure" in numerous songs suggest that this shorthand is widely recognized within some subcultures. Although epilepsy has frequently been associated with female sexual availability in other creative art forms, this novel use of the language of epilepsy represents a contemporary departure in the artistic application of epilepsy-related images and associations in the 21st century.

    Full Text Available The science plays a crucial role in the modern society, and the popularization of science in its electronic form is closely related to the rise and development of the World Wide Web. Since 1990s -the introduction of the Web as a part of the Internet- the science popularization has become more and more involved in the web-based society. Therefore, the Web has become an important technical support of the science popularization. The Web, on the one hand, has increased the accessibility, visibility and popularity of science and scientific research. On the other hand, the increased accessibility and visibility has also increased the citations and research impact or educational impact received by a popular journal or a paper. Science popularization has now made an important step forward, because the Web contributes today as an effective means of improving the public understanding of science. The Web has made it possible to popularize the science via popular search engines. The Web creates a link between specialists and the public; in short, between science and common sense, just by a hyperlink. The science popularization is an attempt to reduce the distance standing between science specialists and the public. Science popularization is interpretation of scientific information (science intended for a general audience, rather than for other experts or students. Science popularization via the Web is a programme that takes science to web users with an objective of making them aware of the efforts, achievements and advances of science. Such programmes could include e-books, e-conferences, e-newspapers, online journalism, online workshops, seminars, and meetings, electronic forums, open-access journals, audio-visiual material, etc.

    Full Text Available Turf soil bacterial isolate Delftia sp. VM4 can degrade exogenous N-acyl homoserine lactone (AHL, hence it effectively attenuates the virulence of bacterial soft rot pathogen Pectobacterium carotovorum subsp. carotovorum strain BR1 (Pcc BR1 as a consequence of quorum sensing inhibition.Isolated Delftia sp. VM4 can grow in minimal medium supplemented with AHL as a sole source of carbon and energy. It also possesses the ability to degrade various AHL molecules in a short time interval. Delftia sp. VM4 suppresses AHL accumulation and the production of virulence determinant enzymes by Pcc BR1 without interference of the growth during co-culture cultivation. The quorum quenching activity was lost after the treatment with trypsin and proteinase K. The protein with quorum quenching activity was purified by three step process. Matrix assisted laser desorption/ionization-time of flight (MALDI-TOF and Mass spectrometry (MS/MS analysis revealed that the AHL degrading enzyme (82 kDa demonstrates homology with the NCBI database hypothetical protein (Daci_4366 of D. acidovorans SPH-1. The purified AHL acylase of Delftia sp. VM4 demonstrated optimum activity at 20-40°C and pH 6.2 as well as AHL acylase type mode of action. It possesses similarity with an α/β-hydrolase fold protein, which makes it unique among the known AHL acylases with domains of the N-terminal nucleophile (Ntn-hydrolase superfamily. In addition, the kinetic and thermodynamic parameters for hydrolysis of the different AHL substrates by purified AHL-acylase were estimated. Here we present the studies that investigate the mode of action and kinetics of AHL-degradation by purified AHL acylase from Delftia sp.

    2013-07-01

    Full Text Available Gender has been an important area of research in the field of popular music studies. Numerous scholars have found that contemporary popular music functions as a locus of diverse constructions and expressions of gender. While most studies focus on content analyses of popular music, there is still a need for more research on audience’s perception of popular music’s messages. This study examined adult Malay listeners’ perceptions of gender messages in contemporary Malay songs. A total of 16 contemporary Malay songs were analysed using Fairclough’s (1992 method of text analysis. The content of the songs that conveyed messages about gender were the basis for analysis. The results showed that the messages revolve mainly around socially constructed gender roles and expectations in romantic relationships. Gender stereotypes are also used in the songs to reinforce men’s and women’s roles in romantic relationships. The results also showed that, while listeners acknowledge the songs’ messages about gender, their own perceptions of gender and what it means to be a gendered being in today’s world are neither represented nor discussed fully in the songs analysed. It is hoped the findings from this, particularly the mismatch between projected and perceived notions of gender, contribute to the field of popular Malay music studies in particular, and popular music studies in general where gender messages in popular songs and their influence on listeners’ perceptions of their own gender is concerned.

    The mass media has an enormous influence on adolescent women and their perceptions about the world and themselves. Teen magazines are a favoured form of the mass media, thus they were chosen for this research project. The aim of this paper is to report a study exploring the messages of health and health-related material in teen magazines from the perspective of adolescents. Knowledge of how adolescents perceive teen magazine messages can be used in the care of this client group. Interpretive inquiry, a substantively driven research approach, was used for the project. A convenience sample of 12 adolescents, aged 12-18 years, participated in two focus groups, and selected images and texts from popular North American teen magazines (YM, Teen, and Seventeen) to discuss. Focus group discussions were audiotaped and then transcribed. Individual interviews with the adolescents were also completed to obtain additional data. Audiotaped interviews were analysed using Gadamer's hermeneutic ideas about 'claim' or 'address'. The findings indicate that teen magazines promote particular expectations about health and health-related activities. Participants noted that the magazines promote the message of perfection by portraying models with perfect eyes, teeth and bodies. The magazines provide ideals of thinness which are presented in a seemingly attainable fashion. Participants stated that magazines suggest that adolescent women need male attention for protection and companionship, in order to achieve fulfillment. Being healthy or whole seemed to be dependent on the adolescent reader embracing and becoming the ideals portrayed in teen magazines. In order to provide relevant and sensitive health care, health care providers need to be cognizant of the persistent demands placed on adolescents by teen magazines and the mass media in general. Media messages and their influences need to be discussed with adolescents, either in school health programmes or clinician visits.

  5. Reformulation and recontextualization in popularization discourse

    2014-03-01

    Full Text Available The paper takes into consideration the evolution of the concept of popularization and of its main techniques of realization in the last few decades. At first, the use of definitions in popularization discourse is investigated and compared to the practices followed in argumentative and pedagogical texts. Special attention is then devoted to the strategies of reformulation and of recontextualization that are often adopted in this process, and exemplifications are provided to highlight the main functions fulfilled by the use of these rhetorical tools. The social importance of popularization is subsequently highlighted together with a discussion of the possible manipulative risks that may be encountered, particularly for argumentative or promotional purposes. The analysis carried out shows the great complexity of the popularization system, which implies therefore the adoption of an integrated approach in order to clearly identify and carefully describe the various aspects involved in this process.

  6. Passionate Virtue: Conceptions of Medical Professionalism in Popular Romance Fiction.

    Miller, Jessica

    2015-01-01

    Medical romance fiction is a subgenre of popular romance fiction that features medical professionals in their work environment. This essay explores the way professionalism is portrayed in popular medical romance fiction written during the early twenty-first century, a period of significant disruption in both the public image and self-understanding of organized medicine. I analyze a selection of contemporary medical romance novels, published between 2008 and 2012, demonstrating that medical romance fiction is a form of public intervention in apparently insular debates over medical professionalism. I conclude that they promote "nostalgic professionalism," a vision of physicians as a select group of highly educated, self-regulated experts who provide, with a caring and altruistic attitude, a vitally important service to society, while at the same time generating implicit critiques of it.

  7. Constraining models of postglacial rebound using space geodesy: a detailed assessment of model ICE-5G (VM2) and its relatives

    2010-05-01

    Using global positioning system, very long baseline interferometry, satellite laser ranging and Doppler Orbitography and Radiopositioning Integrated by Satellite observations, including the Canadian Base Network and Fennoscandian BIFROST array, we constrain, in models of postglacial rebound, the thickness of the ice sheets as a function of position and time and the viscosity of the mantle as a function of depth. We test model ICE-5G VM2 T90 Rot, which well fits many hundred Holocene relative sea level histories in North America, Europe and worldwide. ICE-5G is the deglaciation history having more ice in western Canada than ICE-4G; VM2 is the mantle viscosity profile having a mean upper mantle viscosity of 0.5 × 1021Pas and a mean uppermost-lower mantle viscosity of 1.6 × 1021Pas T90 is an elastic lithosphere thickness of 90 km; and Rot designates that the model includes (rotational feedback) Earth's response to the wander of the North Pole of Earth's spin axis towards Canada at a speed of ~1° Myr-1. The vertical observations in North America show that, relative to ICE-5G, the Laurentide ice sheet at last glacial maximum (LGM) at ~26 ka was (1) much thinner in southern Manitoba, (2) thinner near Yellowknife (Northwest Territories), (3) thicker in eastern and southern Quebec and (4) thicker along the northern British Columbia-Alberta border, or that ice was unloaded from these areas later (thicker) or earlier (thinner) than in ICE-5G. The data indicate that the western Laurentide ice sheet was intermediate in mass between ICE-5G and ICE-4G. The vertical observations and GRACE gravity data together suggest that the western Laurentide ice sheet was nearly as massive as that in ICE-5G but distributed more broadly across northwestern Canada. VM2 poorly fits the horizontal observations in North America, predicting places along the margins of the Laurentide ice sheet to be moving laterally away from the ice centre at 2 mm yr-1 in ICE-4G and 3 mm yr-1 in ICE-5G, in

  8. ARC-VM: An architecture real options complexity-based valuation methodology for military systems-of-systems acquisitions

    Science.gov (United States)

    Domercant, Jean Charles

    The combination of today's national security environment and mandated acquisition policies makes it necessary for military systems to interoperate with each other to greater degrees. This growing interdependency results in complex Systems-of-Systems (SoS) that only continue to grow in complexity to meet evolving capability needs. Thus, timely and affordable acquisition becomes more difficult, especially in the face of mounting budgetary pressures. To counter this, architecting principles must be applied to SoS design. The research objective is to develop an Architecture Real Options Complexity-Based Valuation Methodology (ARC-VM) suitable for acquisition-level decision making, where there is a stated desire for more informed tradeoffs between cost, schedule, and performance during the early phases of design. First, a framework is introduced to measure architecture complexity as it directly relates to military SoS. Development of the framework draws upon a diverse set of disciplines, including Complexity Science, software architecting, measurement theory, and utility theory. Next, a Real Options based valuation strategy is developed using techniques established for financial stock options that have recently been adapted for use in business and engineering decisions. The derived complexity measure provides architects with an objective measure of complexity that focuses on relevant complex system attributes. These attributes are related to the organization and distribution of SoS functionality and the sharing and processing of resources. The use of Real Options provides the necessary conceptual and visual framework to quantifiably and traceably combine measured architecture complexity, time-valued performance levels, as well as programmatic risks and uncertainties. An example suppression of enemy air defenses (SEAD) capability demonstrates the development and usefulness of the resulting architecture complexity & Real Options based valuation methodology.

    Velocity map imaging (VMI) is used in mass spectrometry and in angle resolved photo-electron spectroscopy to determine the lateral momentum distributions of charged particles accelerated towards a detector. VM-images are composed of projected Newton spheres with a common centre. The 2D images are usually evaluated by a decomposition into base vectors each representing the 2D projection of a set of particles starting from a centre with a specific velocity distribution. We propose to evaluate 1D projections of VM-images in terms of 1D projections of spherical functions, instead. The proposed evaluation algorithm shows that all distribution information can be retrieved from an adequately chosen set of 1D projections, alleviating the numerical effort for the interpretation of VM-images considerably. The obtained results produce directly the coefficients of the involved spherical functions, making the reconstruction of sliced Newton spheres obsolete.

    This work describes a new specific, sensitive, and rapid stable isotope dilution method for the simultaneous detection of the organophosphorus nerve agents (OPNAs) tabun (GA), sarin (GB), soman (GD), cyclosarin (GF), VR, VX, and VM adducts to tyrosine (Tyr). Serum, plasma, and lysed whole blood samples (50 μL) were prepared by protein precipitation followed by digestion with Pronase. Specific Tyr adducts were isolated from the digest by a single solid phase extraction (SPE) step, and the analytes were separated by reversed-phase ultra high performance liquid chromatography (UHPLC) gradient elution in less than 2 min. Detection was performed on a triple quadrupole tandem mass spectrometer using time-triggered selected reaction monitoring (SRM) in positive electrospray ionization (ESI) mode. The calibration range was characterized from 0.100-50.0 ng/mL for GB- and VR-Tyr and 0.250-50.0 ng/mL for GA-, GD-, GF-, and VX/VM-Tyr (R(2) ≥ 0.995). Inter- and intra-assay precision had coefficients of variation of ≤17 and ≤10%, respectively, and the measured concentration accuracies of spiked samples were within 15% of the targeted value for multiple spiking levels. The limit of detection was calculated to be 0.097, 0.027, 0.018, 0.074, 0.023, and 0.083 ng/mL for GA-, GB-, GD-, GF-, VR-, and VX/VM-Tyr, respectively. A convenience set of 96 serum samples with no known nerve agent exposure was screened and revealed no baseline values or potential interferences. This method provides a simple and highly specific diagnostic tool that may extend the time postevent that a confirmation of nerve agent exposure can be made with confidence.

  16. Evolution of popularity in given names

    An individual's identity in a human society is specified by his or her name. Differently from family names, usually inherited from fathers, a given name for a child is often chosen at the parents' disposal. However, their decision cannot be made in a vacuum but affected by social conventions and trends. Furthermore, such social pressure changes in time, as new names gain popularity while some other names are gradually forgotten. In this paper, we investigate how popularity of given names has evolved over the last century by using datasets collected in Korea, the province of Quebec in Canada, and the United States. In each of these countries, the average popularity of given names exhibits typical patterns of rise and fall with a time scale of about one generation. We also observe that notable changes of diversity in given names signal major social changes.

  17. Space activities and global popular music culture

    Science.gov (United States)

    Wessels, Allison Rae; Collins, Patrick

    During the "space age" era, space activities appear increasingly as a theme in Western popular music, as they do in popular culture generally. In combination with the electronics and tele-communications revolution, "pop/rock" music has grown explosively during the space age to become an effectively global culture. From this base a number of trends are emerging in the pattern of influences that space activities have on pop music. The paper looks at the use of themes and imagery in pop music; the role of space technology in the modern "globalization" of pop music; and current and future links between space activities and pop music culture, including how public space programmes are affected by its influence on popular attitudes.

  19. Intramural optical mapping of V(m) and Ca(i)2+ during long-duration ventricular fibrillation in canine hearts.

    Science.gov (United States)

    Kong, Wei; Ideker, Raymond E; Fast, Vladimir G

    2012-03-15

    Intramural gradients of intracellular Ca(2+) (Ca(i)(2+)) Ca(i)(2+) handling, Ca(i)(2+) oscillations, and Ca(i)(2+) transient (CaT) alternans may be important in long-duration ventricular fibrillation (LDVF). However, previous studies of Ca(i)(2+) handling have been limited to recordings from the heart surface during short-duration ventricular fibrillation. To examine whether abnormalities of intramural Ca(i)(2+) handling contribute to LDVF, we measured membrane voltage (V(m)) and Ca(i)(2+) during pacing and LDVF in six perfused canine hearts using five eight-fiber optrodes. Measurements were grouped into epicardial, midwall, and endocardial layers. We found that during pacing at 350-ms cycle length, CaT duration was slightly longer (by ≃10%) in endocardial layers than in epicardial layers, whereas action potential duration (APD) exhibited no difference. Rapid pacing at 150-ms cycle length caused alternans in both APD (APD-ALT) and CaT amplitude (CaA-ALT) without significant transmural differences. For 93% of optrode recordings, CaA-ALT was transmurally concordant, whereas APD-ALT was either concordant (36%) or discordant (54%), suggesting that APD-ALT was not caused by CaA-ALT. During LDVF, V(m) and Ca(i)(2+) progressively desynchronized when not every action potential was followed by a CaT. Such desynchronization developed faster in the epicardium than in the other layers. In addition, CaT duration strongly increased (by ∼240% at 5 min of LDVF), whereas APD shortened (by ∼17%). CaT rises always followed V(m) upstrokes during pacing and LDVF. In conclusion, the fact that V(m) upstrokes always preceded CaTs indicates that spontaneous Ca(i)(2+) oscillations in the working myocardium were not likely the reason for LDVF maintenance. Strong V(m)-Ca(i)(2+) desynchronization and the occurrence of long CaTs during LDVF indicate severely impaired Ca(i)(2+) handling and may potentially contribute to LDVF maintenance.

  2. Darwin and the popularization of evolution.

    Evolution was popularized from 1860 to 1900 in the USA and Britain in a wide variety of media. Here I investigate traditional texts associated with the intellectual elite, including philosophical or scientific monographs, sermons, and published lectures. Evolution was rarely popularized in ways that reflected Darwin's major contribution to biology, his theory of natural selection. This meant that the reading audience more often encountered an alternative to Darwin's naturalistic, non-directional and non-progressive evolutionary perspective. There were at least four different versions of evolution circulating in the period from 1860 to 1900, and only one conformed to Darwin's vision.

By outlining a theoretical framework that captures uses of history, the paper analyses popular history magazine articles from five European countries all dealing with the outbreak of World War I. The study finds that while the studied articles provide a rather heterogeneous view of the causes of the Great War, they can be used to discuss and analyse the importance of perspective in history, thus offering an opportunity to further a more disciplinary historical understanding.

We show how these metrics allow to classify albums according to their current popularity or their belonging to expert-made lists of important albums. In this way, we provide the scientific community and the public at large with quantitative tools to tell apart popular albums from culturally or aesthetically relevant artworks.

    The freezing of water can initiate at electrically conducting electrodes kept at a high electric potential or at charged electrically insulating surfaces. The microscopic mechanisms of these phenomena are unknown, but they must involve interactions between water molecules and electric fields. This paper investigates the effect of uniform electric fields on the homogeneous nucleation of ice in supercooled water. Electric fields were applied across drops of water immersed in a perfluorinated liquid using a parallel-plate capacitor; the drops traveled in a microchannel and were supercooled until they froze due to the homogeneous nucleation of ice. The distribution of freezing temperatures of drops depended on the rate of nucleation of ice, and the sensitivity of measurements allowed detection of changes by a factor of 1.5 in the rate of nucleation. Sinusoidal alternation of the electric field at frequencies from 3 to 100 kHz prevented free ions present in water from screening the electric field in the bulk of drops. Uniform electric fields in water with amplitudes up to (1.6 ± 0.4) × 10(5) V/m neither enhanced nor suppressed the homogeneous nucleation of ice. Estimations based on thermodynamic models suggest that fields in the range of 10(7)-10(8) V/m might cause an observable increase in the rate of nucleation.

    BCL-2 is a multifunctional protein involved in the regulation of apoptosis, cell cycle progression and neural developmental processes. Its function in the latter process is not well understood and needs further elucidation. Therefore, we characterized the protein expression kinetics of BCL-2 and associated regulatory proteins of the intrinsic apoptosis pathway during the process of neuronal differentiation in ReNcell VM cells with and without functional inhibition of BCL-2 by its competitive ligand HA14-1. Inhibition of BCL-2 caused a diminished BCL-2 expression and higher levels of cleaved BAX, activated Caspase-3 and cleaved PARP, all pro-apoptotic markers, when compared with untreated differentiating cells. In parallel, flow cytometric analysis of HA14-1-treated cells revealed a delayed differentiation into HuC/D+ neuronal cells when compared to untreated differentiating cells. In conclusion, BCL-2 possess a protective function in fully differentiated ReNcell VM cells. We propose that the pro-survival signaling of BCL-2 is closely connected with its stimulatory effects on neurogenesis of human neural progenitor cells.

    In this paper, we present a quantitative performance analysis of data analytics applications running on multi-core virtual machines. Such environments form the core of cloud computing. In addition, data analytics applications, such as Cassandra and Hadoop, are becoming increasingly popular on cloud computing platforms. This convergence necessitates a better understanding of the performance and cost implications of such hybrid systems. For example, the very rst step in hosting applications in virtualized environments, requires the user to con gure the number of virtual processors and the size of memory. To understand performance implications of this step, we benchmarked three Yahoo Cloud Serving Benchmark (YCSB) workloads in a virtualized multi-core environment. Our measurements indicate that the performance of Cassandra for YCSB workloads does not heavily depend on the processing capacity of a system, while the size of the data set is critical to performance relative to allocated memory. We also identi ed a strong relationship between the running time of workloads and various hardware events (last level cache loads, misses, and CPU migrations). From this analysis, we provide several suggestions to improve the performance of data analytics applications running on cloud computing environments.

    This discussion of the relations between folklore and popular medicine in the Amazon takes Canuto Azevedo's story "Filhos do boto" (Children of the porpoise) as an analytical reference point. Replete with elements of cultural reality, folk tales can serve as historical testimonies expressing clashes between different traditions. Folk records are fruit of what is often a quarrelsome dialogue between folklorists, social scientists, physicians, and pajés and their followers, and their analysis should take into account the conditions under which they were produced. Based on the imaginary attached to the figure of the porpoise--a seductive creature with healing powers--the article explores how we might expand knowledge of popular medicine as practiced in the Amazon, where the shamanistic rite known as pajelança cabocla has a strong presence.

    The average US adolescent is exposed to 34 references to alcohol in popular music daily. Although brand recognition is an independent, potent risk factor for alcohol outcomes among adolescents, alcohol brand appearances in popular music have not been assessed systematically. We aimed to determine the prevalence of and contextual elements associated with alcohol brand appearances in US popular music. Qualitative content analysis. We used Billboard Magazine to identify songs to which US adolescents were most exposed in 2005-07. For each of the 793 songs, two trained coders analyzed independently the lyrics of each song for references to alcohol and alcohol brand appearances. Subsequent in-depth assessments utilized Atlas.ti to determine contextual factors associated with each of the alcohol brand appearances. Our final code book contained 27 relevant codes representing six categories: alcohol types, consequences, emotional states, activities, status and objects. Average inter-rater reliability was high (κ = 0.80), and all differences were easily adjudicated. Of the 793 songs in our sample, 169 (21.3%) referred explicitly to alcohol, and of those, 41 (24.3%) contained an alcohol brand appearance. Consequences associated with alcohol were more often positive than negative (41.5% versus 17.1%, P brand appearances were associated commonly with wealth (63.4%), sex (58.5%), luxury objects (51.2%), partying (48.8%), other drugs (43.9%) and vehicles (39.0%). One in five songs sampled from US popular music had explicit references to alcohol, and one-quarter of these mentioned a specific alcohol brand. These alcohol brand appearances are associated commonly with a luxury life-style characterized by wealth, sex, partying and other drugs. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

  1. Nebulous networks: Virginia Woolf and popular astronomy

    Science.gov (United States)

    Henry, Holly Grace

    This study investigates Virginia Woolf's fascination with advances in astronomy and telescopic technologies of the 1920s and 30s. Grounded in the cultural studies of science, and the work of theorists such as Donna Haraway and Bruno Latour, the dissertation reconstructs the complex interconnections between Woolf's fiction and prose writing and an explosive popular interest in astronomy and cosmology. Woolf's aesthetic and political practices were shaped by emerging visualization technologies ranging from astronomical telescopes to the hand-held camera. While her writing provides a focus for this investigation, the dissertation offers close readings of fiction and essays by multiple British authors and science writers in the context of these converging phenomena. As a result of glimpsing tiny worlds through her own telescope, Virginia Woolf formulated a global aesthetic and a global politics. Gazing at the moon and stars reminded her that earth is a planet in space, and that earth's inhabitants must rely on this small, fragile globe for their future survival. The opening chapter establishes the cultural context for the study. In 1923, the American astronomer Edwin Hubble determined that the Andromeda galaxy was located far beyond the limits of the Milky Way, then believed to comprise the entire universe. Hubble's radical reconfiguration of the universe contributed to a pervasive sense, in the modern period, of a decentering and re-scaling of humans in the universe. In the chapters that follow, the dissertation offers readings of Woolf's novels and short fiction in relation to her fascination with astronomy and explores how the wildly popular British cosmologist and science writer, Sir James jeans, had a shaping effect on popular culture and on Woolf's narrative practices and pacifist politics. Despite his oblique connections to what became Bloomsbury, jeans and his popular science texts were to play a considerable role in Woolf's formulation of a global aesthetic.

  3. Cooperation and popularity in spatial games

    2014-11-01

    Selection of the competition opponent is crucial for the evolution of cooperation in evolutionary games. In this work, we introduce a simple rule, incorporating individual popularity via the single parameter α, to study how the selection of the potential strategy sources influences individual behavior traits. For positive α players with high popularity will be considered more likely, while for negative α the opposite holds. Setting α equal to zero returns the frequently adopted random selection of the opponent. We find that positive α (namely, adopting the strategy from a more popular player) promotes the emergence of cooperation, which is robust against different interaction networks and game classes. The essence of this boosting effect can be attributed to the fact: increasing α accelerates the microscopic organization of cooperator clusters to resist the exploitation of defectors. Moreover, we also demonstrated that the introduction of a new mechanism alters the impact of uncertainty by strategy adoption on the evolution of cooperation. We thus present a viable method of understanding the ubiquitous cooperative behaviors in nature and hope that it will inspire further studies to resolve social dilemmas.

    Full Text Available We present vM21 MIPAS temperatures from the lower stratosphere to the lower thermosphere, which cover all optimized resolution measurements performed by MIPAS in the Middle Atmosphere, Upper Atmosphere and NoctiLucent Cloud modes during its lifetime. i.e., from January 2005 to March 2012. The main upgrades with respect to the previous version of MIPAS temperatures (vM11 are the update of the spectroscopic database, the use of a different climatology of atomic oxygen and carbon dioxide, and the improvement of important technical aspects of the retrieval setup (temperature gradient along the line of sight and offset regularizations, apodization accuracy. Additionally, an updated version of ESA calibrated L1b spectra (5.02/5.06 is used. The vM21 temperatures correct the main systematic errors of the previous version because they on average provide a 1–2 K warmer stratopause and middle mesosphere, and a 6–10 K colder mesopause (except in high latitude summers and lower thermosphere. These lead to a remarkable improvement of MIPAS comparisons with ACE-FTS, MLS, OSIRIS, SABER, SOFIE and the two Rayleigh lidars at Mauna Loa and Table Mountain, that, with few specific exceptions, typically exhibit differences smaller than 1 K below 50 km and than 2 K at 50–80 km in spring, autumn, winter at all latitudes, and summer at low to mid-latitudes. Differences in the high latitude summers are typically smaller than 1 K below 50 km, smaller than 2 K at 50–65 km and 5 K at 65–80 km. Differences with the other instruments in the mid-mesosphere are generally negative. MIPAS mesopause is within 4 K of the other instruments measurements, except in the high latitude summers, where it is within 5–10 K of the other instruments, being warmer than SABER, MLS and OSIRIS and colder than ACE-FTS and SOFIE. The agreement in the lower thermosphere is typically better than 5 K, except for high latitudes during spring and summer, where MIPAS usually exhibits larger

    Voltage-gated potassium channels 1.3 (Kv1.3) can be targeted to reduce diet-induced obesity and insulin resistance in mice. Since species-specific differences in Kv1.3 expression and pharmacology have been observed, we tested the effect of Vm24, a high-affinity specific blocker of Kv1.3 channels from Vaejovis mexicanus smithi, on body weight (BW), glucose tolerance and insulin resistance in diet-induced obese rats. Young adult male Wistar rats were switched to a high-fat/high-fructose (HFF) diet. Eighteen days later animals were divided in two groups: vehicle and Vm24 group. Subcutaneous injections were applied every other day until sacrifice 2months later. An additional cohort was maintained on standard chow. The HFF diet promoted obesity. Treatment with Vm24 did not alter various metabolic parameters such as food intake, BW gain, visceral white adipose tissue mass, adipocyte diameter, serum glucose, leptin and thyroid hormone concentrations, brown adipose tissue mass or uncoupling protein-1 expression, and insulin tolerance. Vm24 did reduce basal and glucose-stimulated serum insulin concentrations, serum C-peptide concentration, increased QUICKI, and tended to lower HOMA-IR. Vm24 treatment did not change the activation of insulin receptor substrate-1, but enhanced protein-kinase B activation and membrane glucose-transporter 4 (GLUT4) protein levels in skeletal muscle. In conclusion, in male rats, long-term blockade of Kv1.3 channels with Vm24 does not reduce weight gain and visceral adiposity induced by HFF diet; instead, it reduces serum insulin concentration, and enhances GLUT4 mobilization in skeletal muscle.

    2013-06-01

    Full Text Available Insights from the recent wealth of popular books on neuroscience are offered to suggest a strengthening of theory in information science. Information theory has traditionally neglected the human dimension in favour of 'scientific' theory often derived from the Shannon-Weaver model. Neuroscientists argue in excitingly fresh ways from the evidence of case studies, non-intrusive experimentation and the measurements that can be obtained from technologies that include electroencephalography, positron emission tomography (PET, functional magnetic resonance imaging (fMRI, and magnetoencephalography (MEG. The way in which the findings of neuroscience intersect with ideas such as those of Kahneman on fast and slow thinking and Csikszentmihalyi on flow, is tentatively explored as lines of connection with information science. It is argued that the beginnings of a theoretical underpinning for current web-based information searching in relation to established information retrieval methods can be drawn from this.

The assumption is that online word of mouth makes the understanding of agrotourism more popular, so the aim of this paper is to examine whether the “popularity” of agrotourism has grown on the Internet during past years during which the Internet has recorded exceptional growth. According to that, this paper examines the distributions of using similar keywords with the same meaning - agritourism and agrotourism - during last four years (from June 2007 to June 2011 by use of Google alert and the word agroturizam which is the translation of these words in the Croatian language. Google alert was used as a monitoring tool. The paper analyzes the appearances of these three keywords monthly and daily on Google and additionally analyzes their use on Facebook as the most popular social group nowadays.

    In this paper, we analyze a collaborative filter that answers the simple question: What is popular amongst your friends? While this basic principle seems to be prevalent in many practical implementations, there does not appear to be much theoretical analysis of its performance. In this paper, we partly fill this gap. While recent works on this topic, such as the low-rank matrix completion literature, consider the probability of error in recovering the entire rating matrix, we consider probability of an error in an individual recommendation (bit error rate (BER)). For a mathematical model introduced in [1],[2], we identify three regimes of operation for our algorithm (named Popularity Amongst Friends (PAF)) in the limit as the matrix size grows to infinity. In a regime characterized by large number of samples and small degrees of freedom (defined precisely for the model in the paper), the asymptotic BER is zero; in a regime characterized by large number of samples and large degrees of freedom, the asymptotic B...

    2008-01-01

    We present a method for accurately predicting the long time popularity of online content from early measurements of user access. Using two content sharing portals, Youtube and Digg, we show that by modeling the accrual of views and votes on content offered by these services we can pre- dict the long-term dynamics of individual submissions from initial data. In the case of Digg, measuring access to given stories during the first two hours allows us to forecast their popularity 30 days ahead with remarkable accuracy, while downloads of Youtube videos need to be followed for 10 days to attain the same performance. The differing time scales of the predictions are shown to be due to differences in how content is consumed on the two portals: Digg stories quickly become outdated, while Youtube videos are still found long after they are initially submitted to the portal. We show that predictions are more accurate for submissions for which attention decays quickly, whereas predictions for evergreen content will be pro...

Comparing the discourse features of popular science with research article and textbook science--the last two being target forms for students--it argues that popular science articles cannot serve as models for scientific writing. It does, however, suggest…

  5. Popularity, similarity, and the network extraversion bias.

    Using the emergent friendship network of an incoming cohort of students in an M.B.A. program, we examined the role of extraversion in shaping social networks. Extraversion has two important implications for the emergence of network ties: a popularity effect, in which extraverts accumulate more friends than introverts do, and a homophily effect, in which the more similar are two people's levels of extraversion, the more likely they are to become friends. These effects result in a systematic network extraversion bias, in which people's social networks will tend to be overpopulated with extraverts and underpopulated with introverts. Moreover, the most extraverted people have the greatest network extraversion bias, and the most introverted people have the least network extraversion bias. Our finding that social networks were systematically misrepresentative of the broader social environment raises questions about whether there is a societal bias toward believing other people are more extraverted than they actually are and whether introverts are better socially calibrated than extraverts.

  6. Espacio sagrado y Religiosidad Popular: perspectivas veterotestamentarias

    Full Text Available El artículo, en primer lugar, establece las parámetros de espacio sagrado desde la perspectiva de las ciencias de la religión, como mediación de la experiencia del Absoluto en medio de lo relativo de la experiencia cotidiana, que se funda en él. Enseguida, selecciona una definición de 'religiosidad popular' que resulte instrumentalmente útil para el análisis del fenómeno en el Antiguo Testamento: lo 'popular' se contrapone a lo 'oficial' por el hecho de no ser realizado por el estamento instituido para ello, de modo que pudiendo compartir creencias y ritos, no tiene la garantía oficial de la autenticidad. Por último, trata de presentar el desarrollo de la categoría de espacio sagrado desde el éxodo hasta el exilio. La hipótesis que se plantea sostiene que, ya que desde el éxodo la experiencia de la liberación precedió al culto en un lugar oficial, establecido. Consecuentemente, la crítica profética a las prácticas religiosas acentúan los contenidos de dignidad para la vida de las pobres. La autenticidad de la fe bíblica no viene dada por la relación con la institución, sino por la coherencia con la experiencia del éxodo. Por ello se puede decir que el analogado principal del lugar sagrado es la vida y, por ende, el cuerpo del prójimoThe article in the first place establishes the parameters of the notion of sacred space, from the perspective of the religious sciences, i.e. as a mediation of the experience of the Absolute, amid the ordinary experience. It then provides an instrumental definition of popular religiosity for the analysis of this phenomenon in the Old Testament, where what is popular is opposed to what is official. Even though both forms share beliefs and rites, the latter is not carried out by the duly established institution and therefore lacks the warrant of officially. Finally, the article presents the development of the sacred space from the exodus until the exile, on the hypothesis that from the exodus

    In this paper, we have studied a dynamic model to explain the observed characteristics of websites in the World Wide Web. The dynamic model consists of the self-growth term for each website and the external force term acting on the website. With simulations of the model, we can explain most of the important characteristics of websites. These characteristics include a power-law distribution of the number of visitors to websites, fluctuation in the fractional growth of individual websites, and the relationship between the age and the popularity of the websites. We also investigated a few variants of the model and showed that the ingredients included in the model adequately explain the behavior of the websites.

    Full Text Available The obvious thing to say about popular science publishing in the last twenty years is that there has been a lot of it! That is important in itself. But it also means it is hazardous to offer general comment. The British journalist and commentator Bryan Appleyard recently wrote in the Sunday Times that the “hard stuff” in science was no longer attracting so many readers. Books answering many small questions about the world, or evoking a sense of wonder, do better - he reckons - than those which offer large certainties based on a scientific, or scientistic view of the world. That type, Appleyard claims, dominated the field for years after Steven Hawking’s A Brief History of Time, with its promise of a theory of everything.

    We explore a variety of examples of music inspired by serious astronomy (as opposed to simply an astronomical title or quick allusion to spooning in June to the light of the Moon). The examples are drawn from my recently published catalog of 133 such pieces, including both classical and popular genres of music. We discuss operas based on the life and work of astronomers, six songs based on a reasonable understanding of the properties of black holes, constellation pieces written by composers from around the world who are or were active amateur astronomers, the song that compares walking on the Moon to being in love, the little-known rock song that became a reference in the Astrophysical Journal, pieces that base the patterns of the music on the rhythms of astronomical phenomena, and a number of others.

    The CMS experiment at the LHC accelerator at CERN relies on its computing infrastructure to stay at the frontier of High Energy Physics, searching for new phenomena and making discoveries. Even though computing plays a significant role in physics analysis we rarely use its data to predict the system behavior itself. A basic information about computing resources, user activities and site utilization can be really useful for improving the throughput of the system and its management. In this paper, we discuss a first CMS analysis of dataset popularity based on CMS meta-data which can be used as a model for dynamic data placement and provide the foundation of data-driven approach for the CMS computing infrastructure.

  12. Popular Ensemble Methods: An Empirical Study

    CERN Document Server

    Maclin, R; 10.1613/jair.614

    2011-01-01

    An ensemble consists of a set of individually trained classifiers (such as neural networks or decision trees) whose predictions are combined when classifying novel instances. Previous research has shown that an ensemble is often more accurate than any of the single classifiers in the ensemble. Bagging (Breiman, 1996c) and Boosting (Freund and Shapire, 1996; Shapire, 1990) are two relatively new but popular methods for producing ensembles. In this paper we evaluate these methods on 23 data sets using both neural networks and decision trees as our classification algorithm. Our results clearly indicate a number of conclusions. First, while Bagging is almost always more accurate than a single classifier, it is sometimes much less accurate than Boosting. On the other hand, Boosting can create ensembles that are less accurate than a single classifier -- especially when using neural networks. Analysis indicates that the performance of the Boosting methods is dependent on the characteristics of the data set being exa...

Its point of departure is the argument advanced by Eric Van Young in his book The Other Rebellion (2001 and the debate sparked by its publication. The article also discusses wether or not a “cultural turn” may be said to characterize historical studies of Latin America and compares the political process in Mexico with that of the Andes. It is suggested that we need to take into account, too, the symbolic and cultural world of both Indians and commoners who participated in the political and military actions of “other rebellions”, the outcome of a time of change and general crisis in colonial society.

    Rivers, M. L.; Gualda, G. A.

    2009-05-01

    One of the challenges in tomography is the availability of suitable software for image processing and analysis in 3D. We present here 'tomo_display' and 'vol_tools', two packages created in IDL that enable reconstruction, processing, and visualization of tomographic data. They complement in many ways the capabilities offered by Blob3D (Ketcham 2005 - Geosphere, 1: 32-41, DOI: 10.1130/GES00001.1) and, in combination, allow users without programming knowledge to perform all steps necessary to obtain qualitative and quantitative information using tomographic data. The package 'tomo_display' was created and is maintained by Mark Rivers. It allows the user to: (1) preprocess and reconstruct parallel beam tomographic data, including removal of anomalous pixels, ring artifact reduction, and automated determination of the rotation center, (2) visualization of both raw and reconstructed data, either as individual frames, or as a series of sequential frames. The package 'vol_tools' consists of a series of small programs created and maintained by Guilherme Gualda to perform specific tasks not included in other packages. Existing modules include simple tools for cropping volumes, generating histograms of intensity, sample volume measurement (useful for porous samples like pumice), and computation of volume differences (for differential absorption tomography). The module 'vol_animate' can be used to generate 3D animations using rendered isosurfaces around objects. Both packages use the same NetCDF format '.volume' files created using code written by Mark Rivers. Currently, only 16-bit integer volumes are created and read by the packages, but floating point and 8-bit data can easily be stored in the NetCDF format as well. A simple GUI to convert sequences of tiffs into '.volume' files is available within 'vol_tools'. Both 'tomo_display' and 'vol_tools' include options to (1) generate onscreen output that allows for dynamic visualization in 3D, (2) save sequences of tiffs to disk

    Background A key challenge in human nutrition is the assessment of usual food intake. This is of particular interest given recent proposals of eHealth personalized interventions. The adoption of mobile phones has created an opportunity for assessing and improving nutrient intake as they can be used for digitalizing dietary assessments and providing feedback. In the last few years, hundreds of nutrition-related mobile apps have been launched and installed by millions of users. Objective This study aims to analyze the main features of the most popular nutrition apps and to compare their strategies and technologies for dietary assessment and user feedback. Methods Apps were selected from the two largest online stores of the most popular mobile operating systems—the Google Play Store for Android and the iTunes App Store for iOS—based on popularity as measured by the number of installs and reviews. The keywords used in the search were as follows: calorie(s), diet, diet tracker, dietician, dietitian, eating, fit, fitness, food, food diary, food tracker, health, lose weight, nutrition, nutritionist, weight, weight loss, weight management, weight watcher, and ww calculator. The inclusion criteria were as follows: English language, minimum number of installs (1 million for Google Play Store) or reviews (7500 for iTunes App Store), relation to nutrition (ie, diet monitoring or recommendation), and independence from any device (eg, wearable) or subscription. Results A total of 13 apps were classified as popular for inclusion in the analysis. Nine apps offered prospective recording of food intake using a food diary feature. Food selection was available via text search or barcode scanner technologies. Portion size selection was only textual (ie, without images or icons). All nine of these apps were also capable of collecting physical activity (PA) information using self-report, the global positioning system (GPS), or wearable integrations. Their outputs focused

    Studies have proposed vastus medialis (VM) muscle cross-sectional area change as a variable associated with cartilage volume loss in knee osteoarthritis (OA). However, the VM also includes fat (%Fat), which may influence knee function. This study analyzed the VM area and %Fat data, separately and in combination, to predict symptoms, cartilage volume loss, and bone marrow lesion (BML) change in knee OA. This study included the according-to-protocol population (n = 143) of a 2-year knee OA randomized clinical trial having magnetic resonance imaging at baseline and 2 years. Correlations used multivariate analyses. Greater baseline value for VM area and %Fat were significantly associated with sex (male, area; female, %Fat), higher body mass index (BMI), and Western Ontario and McMaster Universities Osteoarthritis Index stiffness, function, and total scores (better, high area; worse, high %Fat). Moreover, a VM %Fat increase of 1% at 2 years was associated with worsening of cartilage volume loss in the global knee (P = 0.015) and some subregions (P ≤ 0.030), and with an increment of BML global score change (P Fat, and high BMI identified a subgroup of patients with greater cartilage volume loss in the medial femur (P = 0.028) than the rest of the cohort. These data demonstrated, for the first time, that VM fat content is a strong predictor of cartilage volume loss and the occurrence and progression of BML. Importantly, the combined data of VM area, VM %Fat, and BMI identified patients at higher risk for OA progression. © 2015, American College of Rheumatology.

    Full Text Available The idea to link European citizenship and science education is surely new and uncommon in Poland, but we think, as SEDEC project, that can enrich both the panorama of science popularization outside and inside school system. I checked carefully curricula for every stage of school education looking for the topics concerning the developing of the European citizenship. I found that they are usually connected to the history, geography and some activities developing of the knowledge about generally defined citizenship. The spare topics connected directly to the science are present especially in grammar school curriculum. They may be divided into three groups: exploiting the common heritage, common object of interest and scientific community respectively. In that paper I would like to show how the activities in each of the group may influence the EU citizenship developing process. I am going to emphasize the good choice of science as a context or a medium for EU citizenship education. It may be an important point especially in Central Europe. Additionally I would like to present some auxiliary events that are enable through the external educational resources such as museum and planetarium.

    2009-12-01

    Full Text Available The paper deals with the reproduction of stereotypes about the Balkans in the popular music of ex-Yugoslavia. During the last two decades, over a hundred songs in the Serbian and Croatian languages have been released, specifically mentioning the term Balkan and using it as a metaphor – to evoke and explain the atmosphere of war, poverty, conflict and passion, beauty, love and pride. Based on the analysis of these texts and the frequency of appearance of the themes and motifs, four distinct discourses can be identified: 1. the Balkans as an area of wars and conflicts, 2. the Balkans as an area of joy, passion and fatalism, 3. the primitive and aggressive “male” Balkans vs. the beautiful, proud and resistant “female” Balkans, and 4. the Balkans as Europe’s “Other”. The results show that, despite the inherent fluidity and the unclearness of the very definition of the Balkans and its spatial coverage (and therefore the possibility of distancing oneself from it, mostly negative stereotypes about the Balkans are being reproduced. They are not questioned in that process, but accepted and affirmed as a part of one’s own identity.

    There have been analyzed reasons of the loss of technical education’s popularity. Also, the analysis of known educational and production methods, oriented at the innovative model of development of society, was performed. It is stated that the acquisition of 21st century’s skills as a result of competition of technical education are natural for the DIY ideology, which was realized in the institutions like Fab Lab. The new educational strategy, based on project-based learning, is proposed to be implemented as a special laboratory with equipment, which would be a center of innovative development for students at the Technical University. Moreover, the list of projects planned for implementation, that includes not only projects, specific to a particular university, but also projects, demanded by society as a whole, is specified. It is worth to implement trendy projects in the laboratory, such as toy-like, ecological projects; projects of the energy dependence decrease or the energy efficiency increase, modern digital or innovative projects etc. The student should gain knowledge, skills and, possibly, equipment that are available for immediate usage on the labor market or for the realization of his own projects or the community’s projects in everyday life after the realization of the particular project at the laboratory

The assumption is that, in order to understand the existing associativism today, it is necessary to go back to its predecessors not only because the origins of several current movements date back to last century, but also because the transformations such movements went through as well as the explanation for the rise of new associative and movementalist ways also date back to the last decades of the 20th century. The methodological procedure will present a brief characterization of the associativist scenario in São Paulo in the last decades of the 20th century along with the list of the social movements developed in the capital in those decades. The main data sources are documents and registers of the very movements and the press newspapers: Folha de São Paulo and Estado de São Paulo and books.

  4. BER for recommendations based on local popularity

    Barman, Kishor

    2010-01-01

    Motivated by applications such as recommendation systems, we consider the estimation of a binary random field X obtained by row and column permutations of a block constant random matrix. The estimation of X is based on observations Y, which are obtained by passing entries of X through a binary symmetric channel (BSC) and an erasure channel. We focus on the analysis of a specific algorithm based on local popularity when the erasure rate approaches unity at a specified rate. We study the bit error rate (BER) in the limit as the matrix size approaches infinity. Our main result states that if the cluster size (that is, the size of the constancy blocks in the original matrix) is above a certain threshold, then the BER approaches zero, but below the threshold, the BER is lower bounded away from zero. The lower bound depends on the noise level in the observations and the size of the clusters in relation to the threshold. The threshold depends on the rate at which the erasure probability approaches unity.

    In this paper we present a case study for the design of a low cost solar heating system for a popular residence in an isolated rural community in the state of Rio Grande do Norte. This scaling can be extended to several rural communities that are in the same situation in Brazil as well as the wider use of solar power between the low-income people who do not have the benefits of electricity in their homes or want to have a lower cost of electricity. In this context, there are very interesting alternatives, among which is the replacement of electric heating bath water by heating by solar energy. According to several sources the electric shower, as it is now simple and extremely cheap, is the villain of the national electrical system. It is used in peak hours of consumption, something like 10% of electric generating capacity installed in Brazil, forcing many industries to switch off the machines because of the high cost of electricity during this period. Using the heating by solar energy, we can reduce consumption of electric shower and also increase the use of clean energy in popular homes and in isolated rural communities. This paper will address the use of solar energy with the basic purpose of heating water for bathing in popular residences and in isolated rural areas, using low cost systems, built with easily materials that is found in any area of the country.

El movimiento de las Universidades Populares supo atraer a militantes obreros y a intelectuales —escritores, científicos, profesores y artistas— en la dinámica educativa activada por el Affaire Dreyfus. Tal encuentro entre la chaqueta y la blusa obrera no duró mucho tiempo. Las Universidades Populares murieron porque eran incapaces de imaginar la educación mutua que era el sueño de todos. Este fracaso marcó las conciencias populares durante mucho tiempo, y en el período de entreguerras, repleto de experiencias de educación obrera y proletaria, las Universidades Populares de los años 1900 sirvieron de modelo a seguir o a rechazar.

    2010-01-01

    Citation analysis does not generally take the quality of citations into account: all citations are weighted equally irrespective of source. However, a scholar may be highly cited but not highly regarded: popularity and prestige are not identical measures of esteem. In this study we define popularity as the number of times an author is cited and prestige as the number of times an author is cited by highly cited papers. Information Retrieval (IR) is the test field. We compare the 40 leading researchers in terms of their popularity and prestige over time. Some authors are ranked high on prestige but not on popularity, while others are ranked high on popularity but not on prestige. We also relate measures of popularity and prestige to date of Ph.D. award, number of key publications, organizational affiliation, receipt of prizes/honors, and gender.

  10. The Pulse of News in Social Media: Forecasting Popularity

    Bandari, Roja; Huberman, Bernardo A

    2012-01-01

    News articles are extremely time sensitive by nature. There is also intense competition among news items to propagate as widely as possible. Hence, the task of predicting the popularity of news items on the social web is both interesting and challenging. Prior research has dealt with predicting eventual online popularity based on early popularity. It is most desirable, however, to predict the popularity of items prior to their release, fostering the possibility of appropriate decision making to modify an article and the manner of its publication. In this paper, we construct a multi-dimensional feature space derived from properties of an article and evaluate the efficacy of these features to serve as predictors of online popularity. We examine both regression and classification algorithms and demonstrate that despite randomness in human behavior, it is possible to predict ranges of popularity on twitter with an overall 84% accuracy. Our study also serves to illustrate the differences between traditionally prom...

  11. Comparing 'Popular' and 'State' education in Latin Americaand Europe

    Full Text Available In the 1970s, a radical adult education movement in Latin America, operating outside the state and engaging in what it called 'popular education', sparked world-wide interest in its educational theory and practice. More recently, with a change in state formations in Latin America, the movement has reconsidered its potential relationship with the state. Though Europe has its own history of popular education, some have argued that advanced economies and welfare states co-opted any strong independent educational movement: today popular education is more likely to take place 'within and against' the state, rather than outside it. Based on literature review, personal interviews and site visits, this article (a discusses what is understood by popular education (b outlines the development of popular education in Latin America, examining its relationship with different types of state (c considers differences between Latin America and Europe and what, if anything, popular educators in the two regions might learn from each other.

    Heavy-tailed distributions of meme popularity occur naturally in a model of meme diffusion on social networks. Competition between multiple memes for the limited resource of user attention is identified as the mechanism that poises the system at criticality. The popularity growth of each meme is described by a critical branching process, and asymptotic analysis predicts power-law distributions of popularity with very heavy tails (exponent α <2, unlike preferential-attachment models), similar to those seen in empirical data.

    The panoply of imaging techniques useful in podology is essentially limited to X-rays. Standard "standing" and "lying" X-rays furnish most of the required information. Arthrography is sometimes performed, in particular for trauma or tumour of the ankle. CT scan and MRI make a decisive contribution in difficult cases, notably in fractures and in small fractures without displacement. The two latter techniques are useful in tendon, ligament and muscular disorders, where echography is also informative. Rigorous analysis of radiographies and a good knowledge of foot disorders make these imaging techniques efficacious.

    Conventional approaches to predict the future popularity of products are mainly based on extrapolation of their current popularity, which overlooks the hidden microscopic information under the macroscopic trend. Here, we study diffusion processes on consumer-product and citation networks to exploit the hidden microscopic information and connect consumers to their potential purchase, publications to their potential citers to obtain a prediction for future item popularity. By using the data obtained from the largest online retailers including Netflix and Amazon as well as the American Physical Society citation networks, we found that our method outperforms the accurate short-term extrapolation and identifies the potentially popular items long before they become prominent.

  1. Discipline and passion: meaning, masochism and mythology in popular medical romances.

    Science.gov (United States)

    DeVries, S; Dunlop, M; Goopy, S; Moyle, W; Sutherland-Lockhart, D

    1995-12-01

    This paper is an interpretive analysis of the discourses within popular romance literature, with a particular focus on the genre that includes constructions of the images of nurses and nursing. An historical contrast is made along with examinations of the uses and meanings encompassed within this body of literature, and its messages for women as nurses as it reflects/creates societal change. Deviations from the formulaic nature of these works are explored. Discipline and passion are the recurring themes evident throughout in juxtapositions of romance and power differentials in the hospital/medical scene. The soft-core, sado-masochistic images evident in many titles are explored in a way that raises questions about sexuality, romance, nursing mythology, and the future of this sub-genre of the popular romance.

    Lesion detection in acute stroke by computed-tomography perfusion (CTP) can be affected by incomplete bolus coverage in veins and hypoperfused tissue, so-called bolus truncation (BT), and low contrast-to-noise ratio (CNR). We examined the BT-frequency and hypothesized that image down-sampling and a vascular model (VM) for perfusion calculation would improve normo- and hypoperfused tissue classification. CTP datasets from 40 acute stroke patients were retrospectively analysed for BT. In 16 patients with hypoperfused tissue but no BT, repeated 2-by-2 image down-sampling and uniform filtering was performed, comparing CNR to perfusion-MRI levels and tissue classification to that of unprocessed data. By simulating reduced scan duration, the minimum scan-duration at which estimated lesion volumes came within 10 % of their true volume was compared for VM and state-of-the-art algorithms. BT in veins and hypoperfused tissue was observed in 9/40 (22.5 %) and 17/40 patients (42.5 %), respectively. Down-sampling to 128 x 128 resolution yielded CNR comparable to MR data and improved tissue classification (p = 0.0069). VM reduced minimum scan duration, providing reliable maps of cerebral blood flow and mean transit time: 5 s (p = 0.03) and 7 s (p < 0.0001), respectively. BT is not uncommon in stroke CTP with 40-s scan duration. Applying image down-sampling and VM improve tissue classification. (orig.)

    Twist-1 and miRNAs have been reported to be associated with tumor metastasis and angiogenesis. However, the relationship between Twist-1 and miRNAs and the function of miRNAs remain largely undefined. We aimed to reveal the Twist-1-related miRNA expression profile and to determine whether Twist-1 functions in tumor metastasis and vasculogenic mimicry (VM) by regulating miRNA expression in hepatocellular carcinoma (HCC). Results showed that the expression of miR-27a-3p was consistently down-regulated in HCC cell lines and tissue samples displaying high expression of Twist-1. Both loss- and gain-of-function assays revealed suppressive effects of miR-27a-3p. Low miR-27a-3p expression was significantly associated with early metastasis in HCC. Subsequent investigations revealed that miR-27a-3p mediated the inhibition of epithelial–mesenchymal transition (EMT). Additional experiments showed that VE-cadherin is a direct target of miR-27a-3p and further demonstrated the critical role of miR-27a-3p in suppressing tumor metastasis and VM. Conclusions: Twist-1 up-regulation in HepG2 cells resulted in the differential expression of 18 miRNAs. Among them, miR-27a-3p deregulation contributed to VM and metastasis. The miR-27a-3p-mediated down-regulation of VE-cadherin and inhibition of EMT may be essential for Twist-1 to induce tumor metastasis and VM. Our findings highlight the importance of miR-27a-3p and suggest a promising new strategy for anti-HCC therapy. PMID:26980408

  6. Characterizing and modeling the dynamics of activity and popularity.

    Full Text Available Social media, regarded as two-layer networks consisting of users and items, turn out to be the most important channels for access to massive information in the era of Web 2.0. The dynamics of human activity and item popularity is a crucial issue in social media networks. In this paper, by analyzing the growth of user activity and item popularity in four empirical social media networks, i.e., Amazon, Flickr, Delicious and Wikipedia, it is found that cross links between users and items are more likely to be created by active users and to be acquired by popular items, where user activity and item popularity are measured by the number of cross links associated with users and items. This indicates that users generally trace popular items, overall. However, it is found that the inactive users more severely trace popular items than the active users. Inspired by empirical analysis, we propose an evolving model for such networks, in which the evolution is driven only by two-step random walk. Numerical experiments verified that the model can qualitatively reproduce the distributions of user activity and item popularity observed in empirical networks. These results might shed light on the understandings of micro dynamics of activity and popularity in social media networks.

  7. Popularity Modeling for Mobile Apps: A Sequential Approach.

    The popularity information in App stores, such as chart rankings, user ratings, and user reviews, provides an unprecedented opportunity to understand user experiences with mobile Apps, learn the process of adoption of mobile Apps, and thus enables better mobile App services. While the importance of popularity information is well recognized in the literature, the use of the popularity information for mobile App services is still fragmented and under-explored. To this end, in this paper, we propose a sequential approach based on hidden Markov model (HMM) for modeling the popularity information of mobile Apps toward mobile App services. Specifically, we first propose a popularity based HMM (PHMM) to model the sequences of the heterogeneous popularity observations of mobile Apps. Then, we introduce a bipartite based method to precluster the popularity observations. This can help to learn the parameters and initial values of the PHMM efficiently. Furthermore, we demonstrate that the PHMM is a general model and can be applicable for various mobile App services, such as trend based App recommendation, rating and review spam detection, and ranking fraud detection. Finally, we validate our approach on two real-world data sets collected from the Apple Appstore. Experimental results clearly validate both the effectiveness and efficiency of the proposed popularity modeling approach.

    Differences in popularity are a key aspect of status in virtually all human groups and shape social interactions within them. Little is known, however, about how we track and neurally represent others’ popularity. We addressed this question in two real-world social networks using sociometric methods to quantify popularity. Each group member (perceiver) viewed faces of every other group member (target) while whole-brain functional MRI data were collected. Independent functional localizer tasks were used to identify brain systems supporting affective valuation (ventromedial prefrontal cortex, ventral striatum, amygdala) and social cognition (dorsomedial prefrontal cortex, precuneus, temporoparietal junction), respectively. During the face-viewing task, activity in both types of neural systems tracked targets’ sociometric popularity, even when controlling for potential confounds. The target popularity–social cognition system relationship was mediated by valuation system activity, suggesting that observing popular individuals elicits value signals that facilitate understanding their mental states. The target popularity–valuation system relationship was strongest for popular perceivers, suggesting enhanced sensitivity to differences among other group members’ popularity. Popular group members also demonstrated greater interpersonal sensitivity by more accurately predicting how their own personalities were perceived by other individuals in the social network. These data offer insights into the mechanisms by which status guides social behavior. PMID:26598684

    Previous research has indicated that peer popularity is associated with aggressive behavior. However, it is not yet clear whether popularity is uniquely related to different functions of aggression. In this study, we examined associations between peer-perceived popularity, and reactive and proactive aggression using a cross-sectional and a longitudinal design. Yearly sociometric measures of popularity, and reactive and proactive aggression were gathered from 266 seventh and eight grade adolescents (Mage grade 7 = 12.80, SDage  = .40). Popularity was positively correlated with proactive aggression and negatively correlated with reactive aggression, both concurrently as over time. Curvilinear trends indicated that a significant minority of low versus high popular adolescents showed both functions of aggression. Somewhat stronger effects of popularity on proactive aggression were found for boys than girls. Stably popular adolescents showed the highest levels of proactive aggression, whereas stably unpopular youth showed the highest levels of reactive aggression. Implications and directions for future research are discussed.

When women immigrants embroidered images and sayings on wall hangings or kitchen towels made of rustic fabric, they helped nourish the dream of a better life, sought by all and achieved by some. The objects crafted by these twentieth-century Penelopes bear witness to a way of doing, thinking, and acting. Local museums and exhibits have fostered the recovery of old-time embroidery techniques and themes; sold at open-air markets and regional festivals, these products represent income for women whose age excludes them from the formal labor market.

    The construction of a course focused on remote sensing is important because it cultivates college students' geographic abilities and popularizes remote sensing technology. Using internet datasets, this article compares data from general undergraduate courses at almost 100 universities located in the United States and China with 3 years of experimental teaching data from the general undergraduate "Remote sensing Region" course at Beijing Normal University. The comparison focuses on curricular concepts, course content, website construction and the popularity of the remote sensing topic. Our research shows that the "remote sensing region" course can promote the geographic abilities of college students by popularizing remote sensing observation technology. The course can improve the overall quality of college students by breaking major barriers, and it can promote global and national consciousness by presenting material with global and regional relevancy. Remote sensing imaging has become known as the third most intuitive geographic language after text and maps. The general remote sensing course have the three following developmental qualities: interdisciplinarity, popularization and internationalization.

    It is well-known that social influences affect consumption decisions. We used functional magnetic resonance imaging (fMRI) to elucidate the neural mechanisms associated with social influence with regard to a common consumer good: music. Our study population was adolescents, age 12-17. Music is a common purchase in this age group, and it is widely believed that adolescent behavior is influenced by perceptions of popularity in their reference group. Using 15-s clips of songs from MySpace.com, we obtained behavioral measures of preferences and neurobiological responses to the songs. The data were gathered with, and without, the overall popularity of the song revealed. Song popularity had a significant effect on the participants' likability ratings of the songs. fMRI results showed a strong correlation between the participants' rating and activity in the caudate nucleus, a region previously implicated in reward-driven actions. The tendency to change one's evaluation of a song was positively correlated with activation in the anterior insula and anterior cingulate, two regions that are associated with physiological arousal and negative affective states. Sensitivity to popularity was linked to lower activation levels in the middle temporal gyrus, suggesting a lower depth of musical semantic processing. Our results suggest that a principal mechanism whereby popularity ratings affect consumer choice is through the anxiety generated by the mismatch between one's own preferences and others'. This mismatch anxiety motivates people to switch their choices in the direction of the consensus. Our data suggest that this is a major force behind the conformity observed in music tastes in some teenagers.

    Full Text Available The expansion of the Web and its information in all aspects of life raises the concern of how to trust information published on the Web especially in cases where publisher may not be known. Websites strive to be more popular and make themselves visible to search engines and eventually to users. Website popularity can be measured using several metrics such as the Web traffic (e.g. Website: visitors’ number and visited page number. A link or page popularity refers to the total number of hyperlinks referring to a certain Web page. In this study, several top ranked Arabic Websites are selected for evaluating possible Web spam behavior. Websites use spam techniques to boost their ranks within Search Engine Results Page (SERP. Results of this study showed that some of these popular Websites are using techniques that are considered spam techniques according to Search Engine Optimization guidelines.

  2. Mainstreaming kink: the politics of BDSM representation in U.S. popular media.

    Science.gov (United States)

    Weiss, Margot D

    2006-01-01

    This article explores nonpractitioners' understandings of and responses to the increasingly mainstream representation of BDSM in U.S. media, focusing on the film Secretary (Shainberg, 2002). Survey, focus group, and interview data indicate that popular images of SM promote the acceptance and understanding of sexual minorities through two mechanisms: acceptance via normalization, and understanding via pathologizing. Rather than challenging the privileged status of normative sexuality, these mechanisms reinforce boundaries between protected/privileged and policed/pathological sexualities. Instead of celebrating increased representation, this article argues that political energy might be directed toward the desire that the popularity of BDSM representations signifies: the desire to encounter authentic, undisciplined, and noncommodified representations that would transgress the sexual norms of American postmodern consumer culture.

    Media framing of infant feeding has the ability to influence knowledge and views of the barriers, benefits, and solutions inherent in breastfeeding or formula-feeding. This study examined how seven popular U.S. parenting, general women's, and African American magazines framed breastfeeding and formula-feeding messages to determine whether a sense-making approach was used and the extent to which visual images portrayed feeding practices. Analysis included 615 articles published from 1997 to 2003 that referred to infant feeding. Text and images were analyzed. The magazines provided more information on breastfeeding than formula feeding. Parenting magazines included more advice than barriers or benefits. African American magazines presented more breastfeeding benefits, and general women's magazines contained the least infant-feeding information. Messages were focused on individualized breastfeeding barriers and advice, seldom covered social and environmental issues, and placed much of the responsibility of infant feeding on the mother, while the role of social and partner support was diminished. Bottle-feeding images were nearly as common as breastfeeding images. Findings can be used by public health practitioners to increase the likelihood of reaching certain target audiences through popular magazines.

    Conclusions: While greater popularity of apps was associated with higher quality, the overall quality of commercial dietary weight-management apps remains suboptimal. Popular weight-management apps are useful for self-monitoring, however are lacking in the recognised behavioural change techniques that may facilitate changes in health behaviours. With the majority of these apps designed for self-directed management, strategies to improve the rigour of these apps are warranted and commercial app developers could benefit from collaboration with behavioural researchers.

    Diffusion tensor imaging (DTI) data has traditionally been displayed as a grayscale functional anisotropy map (GSFM) or color coded orientation map (CCOM). These methods use black and white or color with intensity values to map the complex multidimensional DTI data to a two-dimensional image. Alternative visualization techniques, such as V max maps utilize enhanced graphical representation of the principal eigenvector by means of a headless arrow on regular nonstereoscopic (VM) or stereoscopic display (VMS). A survey of clinical utility of patients with intracranial neoplasms was carried out by 8 neuroradiologists using traditional and nontraditional methods of DTI display. Pairwise comparison studies of 5 intracranial neoplasms were performed with a structured questionnaire comparing GSFM, CCOM, VM, and VMS. Six of 8 neuroradiologists favored V max maps over traditional methods of display (GSFM and CCOM). When comparing the stereoscopic (VMS) and the non-stereoscopic (VM) modes, 4 favored VMS, 2 favored VM, and 2 had no preference. In conclusion, processing and visualizing DTI data stereoscopically is technically feasible. An initial survey of users indicated that V max based display methodology with or without stereoscopic visualization seems to be preferred over traditional methods to display DTI data.

    Full Text Available Recently, microblogging is widely studied by the researchers in the domain of the online social network (OSN. How to evaluate the popularities of microblogging users is an important research field, which can be applied to commercial advertising, user behavior analysis and information dissemination, and so forth. Previous studies on the evaluation methods cannot effectively solve and accurately evaluate the popularities of the microbloggers. In this paper, we proposed an electromagnetic field theory based model to analyze the popularities of microbloggers. The concept of the source in microblogging field is first put forward, which is based on the concept of source in the electromagnetic field; then, one’s microblogging flux is calculated according to his/her behaviors (send or receive feedbacks on the microblogging platform; finally, we used three methods to calculate one’s microblogging flux density, which can represent one’s popularity on the microblogging platform. In the experimental work, we evaluated our model using real microblogging data and selected the best one from the three popularity measure methods. We also compared our model with the classic PageRank algorithm; and the results show that our model is more effective and accurate to evaluate the popularities of the microbloggers.

    Social media, regarded as two-layer networks consisting of users and items, turn out to be the most important channels for access to massive information in the era of Web 2.0. The dynamics of human activity and item popularity is a crucial issue in social media networks. In this paper, by analyzing the growth of user activity and item popularity in four empirical social media networks, i.e., Amazon, Flickr, Delicious and Wikipedia, it is found that cross links between users and items are more likely to be created by active users and to be acquired by popular items, where user activity and item popularity are measured by the number of cross links associated with users and items. This indicates that users generally trace popular items, overall. However, it is found that the inactive users much more severely trace popular items than the active users. Inspired by empirical analysis, we propose an evolving model for such networks, in which the evolution is driven only by two-step random walk. Numerical experiments...

  10. Popularizing biomedical information on an online health forum

    2015-04-01

    Full Text Available Given the increasing importance assumed by online health forums as a form of doctor-patient communication, this study describes the types of dialogic and polylogic interactions that develop in this type of communicative event, focusing on a corpus of threads drawn from an “Ask a Doctor” forum in the area of cardiology. Adopting a discourse analytical approach, the investigation illustrates how these forums may popularize biomedical knowledge. After describing the shifting conceptualization of popularization, we present a new conceptualization of Web 2.0 popularization which we call “oblique popularization”, as it is indirect, user-generated, dialogic and polylogic, and targeted. In particular, this study characterizes the online health forum as a Web 2.0-style popularization tool. It does so not only because biomedical information communicated to a single inquirer is also available to the whole population, but also because the function of the online forum as a medium of popularization is discursively acknowledged by the participants. The study also explores what explanatory tools (such as definitions, analogies, exemplifications, and generalizations are used by the experts to present complex or technical information. The analysis shows that biomedical information is circulated on a health forum by a complex network of participants, and that e-patients’ posts may also serve as prompters of popularization

    Fiandrotti, Attilio; Chakareski, Jacob; Frossard, Pascal

    2010-07-01

    We propose a framework for popularity-driven rate allocation in H.264/MVC-based multi-view video communications when the overall rate and the rate necessary for decoding each view are constrained in the delivery architecture. We formulate a rate allocation optimization problem that takes into account the popularity of each view among the client population and the rate-distortion characteristics of the multi-view sequence so that the performance of the system is maximized in terms of popularity-weighted average quality. We consider the cases where the global bit budget or the decoding rate of each view is constrained. We devise a simple ratevideo- quality model that accounts for the characteristics of interview prediction schemes typical of multi-view video. The video quality model is used for solving the rate allocation problem with the help of an interior point optimization method. We then show through experiments that the proposed rate allocation scheme clearly outperforms baseline solutions in terms of popularity-weighted video quality. In particular, we demonstrate that the joint knowledge of the rate-distortion characteristics of the video content, its coding dependencies, and the popularity factor of each view is key in achieving good coding performance in multi-view video systems.

  13. Does Humor Explain Why Relationally Aggressive Adolescents Are Popular?

    2013-01-01

    The association between relational aggression and popularity during early adolescence is well established. Yet, little is known about why, exactly, relationally aggressive young adolescents are able to achieve and maintain high popular status among peers. The present study investigated the mediating role of humor in the association between relational aggression and popularity during early adolescence. Also considered was whether the association between relational aggression and humor varies according to adolescents’ gender and their friends’ levels of relational aggression. Participants were 265 sixth-grade students (48% female; 41% racial/ethnic minority; Mage = 12.04 years) who completed peer nomination and friendship measures in their classrooms at two time points (Wave 1: February; Wave 2: May). The results indicated that Wave 1 relational aggression was related to Wave 1 and 2 popularity indirectly through Wave 1 humor, after accounting for the effects of Wave 1 physical aggression, ethnicity, and gender. Additional analyses showed that relational aggression and humor were related significantly only for boys and for young adolescents with highly relationally aggressive friends. The results support the need for further research on humor and aggression during early adolescence and other mechanisms by which relationally aggressive youth achieve high popular status.

  15. The genre of islands: popular fiction and performance geographies

    2016-11-01

    Full Text Available To date, studies of the contribution literature makes to ideas about islands have concentrated on “high” literature. This has left unexamined the largest proportion of literature featuring islands. If one of the goals of island studies is to interrogate prevailing ideas about “islandness,” then the islands that crowd the storyworlds of popular genres merit close attention. This article focuses on popular fiction to advocate “performative geographies” as a key concept for island studies of literature, and indeed other domains of culture. Popular genres are undeniably sources of distraction and entertainment for billions of readers. However, they are also systems of meaning, which have an immeasurable impact on our geographical awareness and imagination. This article uses critical snapshots of Anglophone island-set crime fiction and popular romance fiction to show the meta-geographical potential of popular novels as they both depict and reflect on islands as performative geographies, or spaces that make and unmake individual and social identities.

    2014-01-01

    How does a new startup drive the popularity of competing websites into oblivion like Facebook famously did to MySpace? This question is of great interest to academics, technologists, and financial investors alike. In this work we exploit the singular way in which Facebook wiped out the popularity of MySpace, Hi5, Friendster, and Multiply to guide the design of a new popularity competition model. Our model provides new insights into what Nobel Laureate Herbert A. Simon called the "marketplace of attention," which we recast as the attention-activity marketplace. Our model design is further substantiated by user-level activity of 250,000 MySpace users obtained between 2004 and 2009. The resulting model not only accurately fits the observed Daily Active Users (DAU) of Facebook and its competitors but also predicts their fate four years into the future.

Quickly did this popular bank became a commercial bank like so many others that were operating in the Portuguese market at the time. After a promising start, the bank suddenly went through some hardships, due to the crisis of the 1920’s and to bad investments, and eventually was shut down, after eleven years of activity.

  4. Disk storage management for LHCb based on Data Popularity estimator

    INSPIRE-00545541; Charpentier, Philippe; Ustyuzhanin, Andrey

    2015-12-23

    This paper presents an algorithm providing recommendations for optimizing the LHCb data storage. The LHCb data storage system is a hybrid system. All datasets are kept as archives on magnetic tapes. The most popular datasets are kept on disks. The algorithm takes the dataset usage history and metadata (size, type, configuration etc.) to generate a recommendation report. This article presents how we use machine learning algorithms to predict future data popularity. Using these predictions it is possible to estimate which datasets should be removed from disk. We use regression algorithms and time series analysis to find the optimal number of replicas for datasets that are kept on disk. Based on the data popularity and the number of replicas optimization, the algorithm minimizes a loss function to find the optimal data distribution. The loss function represents all requirements for data distribution in the data storage system. We demonstrate how our algorithm helps to save disk space and to reduce waiting times ...

  5. Introduction: ‘Mr Popular Sentiment’: Dickens and Feeling

    2012-04-01

    Full Text Available The introduction to this issue of '19', ‘“Mr Popular Sentiment”: Dickens and Feeling’, considers the turn away from Dickens’s sentimentality in the mid-nineteenth century. Drawing upon nineteenth-century reviews, it argues that Dickens’s sentimental characters and pathetic situations were perceived as politically radical and dangerously biased against the upper classes. This became of particular concern from the 1850s onwards, when an increase in literacy and cheaper publications meant that Dickens’s novels could be read by a cross-class mass-market readership. The reaction against ‘Mr Popular Sentiment’ was, in truth, a reaction to his populism and his popularity.

  6. Examining the popularity trajectory of outsourcing as a management concept

    2017-06-01

    Full Text Available This paper examines the popularity trajectory of outsourcing as a management concept. The paper shows that while outsourcing is an old management practice that has roots that date back centuries, it did not gain widespread popularity as a modern organizational practice until the 1980s. While the initial outsourcing hype and craze of the late 1980s and early 1990s has waned, outsourcing has shown considerable staying power as a management concept, even in the face of counter-movements such as backsourcing and insourcing. Although the experiences with implementation of outsourcing are mixed, outsourcing remains a widely used management concept. However, the current relatively low satisfaction level among users could influence the future popularity trajectory of the outsourcing concept.

    Full Text Available The paper is focused on ideological and political conflicts about popular music in Serbia, as a good example of wrong and confused searching for identity. Basic conflict that author is analyzing is about oriental elements (such as asymmetric rhythmic patterns and melismatic singing and the question if they are legitimate parts of Serbian musical heritage or not. Author is making an analysis of three periods in twentieth century, in which absolutely the same arguments were used, and he's paying special attention to contemporary conflicts, trying to explain why all of the theories are ideologically based. Author is insisting on role market played in development and modernization of popular music in Serbia. The article is ending with some recommendations for better understanding of cultural identity in Serbia, and for recognizing popular music as specific field of interest and research.

The article has been retracted because a similar article had previously been published in the Jugoslovenska medicinska biohemija in 2003. The authors presumed that since the journal was no longer existing, they felt the need to re-publish their work in Acta Neuorologica Scandinavica.

  9. Predicting Key Events in the Popularity Evolution of Online Information

    The popularity of online information generally experiences a rising and falling evolution. This paper considers the “burst”, “peak”, and “fade” key events together as a representative summary of popularity evolution. We propose a novel prediction task—predicting when popularity undergoes these key events. It is of great importance to know when these three key events occur, because doing so helps recommendation systems, online marketing, and containment of rumors. However, it is very challenging to solve this new prediction task due to two issues. First, popularity evolution has high variation and can follow various patterns, so how can we identify “burst”, “peak”, and “fade” in different patterns of popularity evolution? Second, these events usually occur in a very short time, so how can we accurately yet promptly predict them? In this paper we address these two issues. To handle the first one, we use a simple moving average to smooth variation, and then a universal method is presented for different patterns to identify the key events in popularity evolution. To deal with the second one, we extract different types of features that may have an impact on the key events, and then a correlation analysis is conducted in the feature selection step to remove irrelevant and redundant features. The remaining features are used to train a machine learning model. The feature selection step improves prediction accuracy, and in order to emphasize prediction promptness, we design a new evaluation metric which considers both accuracy and promptness to evaluate our prediction task. Experimental and comparative results show the superiority of our prediction solution. PMID:28046121

    Víctor Adrián Díaz Esteves

    2009-01-01

    Full Text Available A partir de un enfoque popular en construcción, este ensayo se propone reflexionar en torno a la noción original de comunicación humana. Asimismo, se aproxima al debate sobre las culturas populares en América Latina, construidas desde los sujetos, caracterizados por dos elementos aparentemente enfrentados, que se entremezclan. Por un lado, los sujetos son consumidores de la oferta rentable y global de los medios masivos; cuya hegemonía responde al rating y al capital. Por otro lado, son productores culturales de sentido e imágenes simbólicas propias, resistentes y en ocasiones, contradictorias. La comunicación popular favorece la producción local y regional; la participación ciudadana, la integración y el cambio social; la igualdad y la democracia. Esta mirada popular de la comunicación, es parte de las mutaciones que la modernidad ha introducido en los países latinoamericanos, y a la vez, define a las culturas populares, no como esa masa homogénea, pasiva y dominada por los mass media, sino conscientes del entrecruzamiento de expresiones sociales, orígenes, gustos, modas y costumbres diversas, en busca de la construcción de comunidades culturales de sentido y respeto en materia de derechos.

  12. Social grievances, popular music and electoral mobilization in Romania

    Directory of Open Access Journals (Sweden)

    Dragoş DRAGOMAN

    2014-12-01

    Full Text Available The general social environment in Romania, as unraveled by the study of a widespread popular music genre called ‘manele’, is dominated by distrust, apathy and disengagement. In part, this is a response to the low political performance of political elites, largely seen as irresponsible and corrupt. By exploiting social and political grievances through the use of such a type of popular music, populist parties in Romania managed to electorally mobilize young people which have not been mobilized before. Although this can be seen as a democratic gain, hate speech and political violence can seriously undermine social and political trust and may prepare the ground for more radical action.

  13. The sociology of popular music, interdisciplinarity and aesthetic autonomy.

    Science.gov (United States)

    Marshall, Lee

    2011-03-01

    This paper considers the impact of interdisciplinarity upon sociological research, focusing on one particular case: the academic study of popular music. 'Popular music studies' is an area of research characterized by interdisciplinarity and, in keeping with broader intellectual trends, this approach is assumed to offer significant advantages. As such, popular music studies is broadly typical of contemporary intellectual and governmental attitudes regarding the best way to research specific topics. Such interdisciplinarity, however, has potential costs and this paper highlights one of the most significant: an over-emphasis upon shared substantive interests and subsequent undervaluation of shared epistemological understandings. The end result is a form of 'ghettoization' within sociology itself, with residents of any particular ghetto displaying little awareness of developments in neighbouring ghettos. Reporting from one such ghetto, this paper considers some of the ways in which the sociology of popular music has been limited by its positioning within an interdisciplinary environment and suggests two strategies for developing a more fully-realized sociology of popular music. First, based on the assumption that a sociological understanding of popular music shares much in common with a sociological understanding of everything else, this paper calls for increased intradisciplinary research between sociologists of varying specialisms. The second strategy, however, involves a reconceptualization of the disciplinary limits of sociology, as it argues that a sociology of popular music needs to accept musical specificity as part of its remit. Such acceptance has thus far been limited not only by an interdisciplinary context but also by the long-standing sociological scepticism toward the analysis of aesthetic objects. As such, this paper offers an intervention into wider debates concerning the remit of sociological enquiry, and whether it is ever appropriate for sociological

  14. Local Variation of Hashtag Spike Trains and Popularity in Twitter.

    We draw a parallel between hashtag time series and neuron spike trains. In each case, the process presents complex dynamic patterns including temporal correlations, burstiness, and all other types of nonstationarity. We propose the adoption of the so-called local variation in order to uncover salient dynamical properties, while properly detrending for the time-dependent features of a signal. The methodology is tested on both real and randomized hashtag spike trains, and identifies that popular hashtags present regular and so less bursty behavior, suggesting its potential use for predicting online popularity in social media.

By computing a shortest path based on the self-similarity matrix calculated from a model of rhythm, segmenting boundaries are found along the di- agonal of the matrix. The cost of a new segment is opti- mized by matching manual...... and automatic segment boundaries. We compile a small song database of 21 randomly selected popular Chinese songs which come from Chinese Mainland, Taiwan and Hong Kong. The segmenting results on the small corpus show that 78% manual segmentation points are detected and 74% auto- matic segmentation points...

    In recent years, academic circles has made important progress in the following studies on the basic connotation of Marxist popularity, the relations between popularity of Marxism and sinicization, the relations between popularity of Marxism and epochal character, the realizing method of popularity of Marxism. Next, study on popularization of Marxism has to make efforts in the following two aspects: the relationship between the popularity of Marxism and socialist theory system with Chinese characteris- tics, and integration of the popularity of Marxism and the ideological and political education. Meanwhile the efforts should be made to deepen the study of Marxism popularity through the process of sinicization of Marxism, to study Marxism popularity from the viewpoint of the three dimensional perspective of the development of Marxism, also to strengthen the research of basic princi- ples of Marxism popularity and deepen the studies of basic forms of Marxism popularity, thus to build a study system of Marxism popularity.

Em primeiro lugar, procuraremos explorar como a elite romana representava os bandidos antigos na literatura satírica, tomando como exemplo passagens das Metamorfoses de Apuleio. Em segundo lugar, procuraremos enfocar a Epigrafia (placas metálicas dedicadas à deusa Sulis Minerva que foram encontradas em Bath, Inglaterra para discutir as imagens do roubo na cultura popular. A evidência epigráfica é fundamental para o estudo das percepções acerca do banditismo e, também, ajuda a proporcionar interpretações mais plurais da cultura e do passado romano.This paper discusses two interrelated topics. The first one explores how the Roman elite represented ancient robbers in satirical literature. In this part I shall comment Apuleius' Metamorphoses. The second one focuses on Epigraphy (metallic tablets dedicated to the godess Sulis Minerva that were found in Bath, England in order to discuss some images of the thievery at Roman popular culture. Archaeological Epigraphic evidence can provide us different approaches to study the banditry perceptions; it can also help us to propose more pluralist approaches to the Roman culture and past.

    Previous work has shown that cellular-level Optical Metabolic Imaging (OMI) of organoids derived from human breast cancer cell-line xenografts accurately and rapidly predicts in vivo response to therapy. To validate OMI as a predictive measure of treatment response in an immune-competent model, we used the polyomavirus middle-T (PyVmT) transgenic mouse breast cancer model. The PyVmT model includes intra-tumoral heterogeneity and a complex tumor microenvironment that can influence treatment responses. Three-dimensional organoids generated from primary PyVmT tumor tissue were treated with a chemotherapy (paclitaxel) and a PI3K inhibitor (XL147), each alone or in combination. Cellular subpopulations of response were measured using the OMI Index, a composite endpoint of metabolic response comprised of the optical redox ratio (ratio of the fluorescence intensities of metabolic co-enzymes NAD(P)H to FAD) as well as the fluorescence lifetimes of NAD(P)H and FAD. Combination treatment significantly decreased the OMI Index of PyVmT tumor organoids (padaptive immunity. Thus, this method is promising for use in humans to predict long-term treatment responses accurately and rapidly, and could aid in clinical treatment planning.

  6. Bringing American Popular Culture to the English Departments in Indonesia*

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available One outcome of the globalization process is the growing influence and dominance of American popular culture. The speed with which American music, films, and goods have flooded the markets worldwide is remarkably high, thanks to the advancement of telecommunication technologies and the Internet. Increased cultural transfer or, more precisely, internationalization of American culture has posed both fear and fascination to other cultures. How do people in the academia respond to this conundrum of cross-cultural contacts? What do we teach when we teach popular culture? What viable research in American popular culture is encouraged so as to result in impartially beneficial impacts for society at large? This paper is to argue that one can become an avid learner or critic of a certain culture when s/he finds meaningful connections between that culture and life itself. The teaching of American popular culture in the English Department, for instance, has to be locally contextualized, learner-participant oriented, and socially self-actualized. In this way, American Studies outside the U. S. may in turn become less centralized as the interchange of cross-cultural understanding takes place concurrently.

    2014-06-01

    This paper describes a popularity prediction tool for data-intensive data management systems, such as ATLAS distributed data management (DDM). It is fed by the DDM popularity system, which produces historical reports about ATLAS data usage, providing information about files, datasets, users and sites where data was accessed. The tool described in this contribution uses this historical information to make a prediction about the future popularity of data. It finds trends in the usage of data using a set of neural networks and a set of input parameters and predicts the number of accesses in the near term future. This information can then be used in a second step to improve the distribution of replicas at sites, taking into account the cost of creating new replicas (bandwidth and load on the storage system) compared to gain of having new ones (faster access of data for analysis). To evaluate the benefit of the redistribution a grid simulator is introduced that is able replay real workload on different data distributions. This article describes the popularity prediction method and the simulator that is used to evaluate the redistribution.

    Full Text Available Strategies for running companies in low-income markets have been in the spotlight in both the academic and the corporate environments.However, the first discussions about the relevance of such markets arose during the 1980s, when scenario-prospecting studies showed that popular markets would provide many opportunities around the year 2000.Indeed, at present, the base of the pyramid has many unaddressed needs that offer business possibilities for those companies that are willing to review their strategies. In this context, product development becomes increasingly important, since products targeting consumers of the C, D and E classes may need different features from those of goods manufactured for the A and B classes.The aim of this study is to revisit past popular market forecasts and to identify development trends for goods that target low- income consumers.Our results indicate that Wright and Johnson’s (1984 studies predicted that Brazil would maintain both qualitative and quantitative progress in its socioeconomic development over the next two decades and that the development of popular products is undergoing a buoyant phase.Several functional perspectives were used to develop an understanding of the phenomenon, especially marketing, engineering and manufacturing.Key words: Future studies.

  1. The End of Insurance? Mexico's Seguro Popular, 2001 - 2007.

    Science.gov (United States)

    Lakin, Jason M

    2010-06-01

    Health system reforms that introduce insurance principles into public health systems (such as national health insurance, internal markets, and separation of purchasers and providers) have been popular in the last two decades. Little is known, however, about the political complexities of transforming existing health services into health insurance systems in developing countries. Mexico's Seguro Popular (Popular Health Insurance) program, introduced in 2003, was an attempt to do exactly this: radically alter the country's existing health service and convert it into health insurance. Popular Health Insurance (PHI) has garnered international attention and has been held up as a model for other countries to follow. Yet little has been written about the political process that led to the reform or the difficulties of implementing it. This article fills that lacuna, offering an assessment of the reform context as well as of the process of formulating, adopting, and implementing it. It argues that, while the reform has improved Mexico's public health service, it has thus far failed to transform that health service into a true insurance system. Limited institutional reform has also left PHI severely underfinanced. The Mexican case is a cautionary tale for reformers who want to transform extant health services into health insurance systems.

    2015-06-15

    Purpose To evaluate the image quality and spectral information of a spectral detector CT (SDCT) scanner using virtual monochromatic (VM) energy images. Methods The SDCT scanner (Philips Healthcare) was equipped with a dual-layer detector and spectral iterative reconstruction (IR), which generates conventional 80–140 kV polychromatic energy (PE) CT images using both detector layers, PE images from the low-energy (upper) and high-energy (lower) detector layers and VM images. A solid water phantom with iodine (2.0–20.0 mg I/ml) and calcium (50.0–600.0 mg Ca/ml) rod inserts was used to evaluate effective energy estimate (EEE) and iodine contrast to noise ratio (CNR). The EEE corresponding to an insert CT number in a PE image was calculated from a CT number fit to the VM image set. Since PE image is prone to beam-hardening artifact EEE may underestimate the actual energy separation from two layers of the detector. A 30-cm-diameter water phantom was used to evaluate noise power spectrum (NPS). The phantoms were scanned at 120 and 140 kV with the same CTDIvol. Results The CT number difference for contrast inserts in VM images (50–150 keV) was 1.3±6% between 120 and 140 kV scans. The difference of EEE calculated from low- and high-energy detector images was 11.5 and 16.7 keV for 120 and 140 kV scans, respectively. The differences calculated from 140 and 100 kV conventional PE images were 12.8, and 20.1 keV from 140 and 80 kV conventional PE images. The iodine CNR increased monotonically with decreased keV. Compared to conventional PE images, the peak of NPS curves from VM images were shifted to lower frequency. Conclusion The EEE results indicates that SDCT at 120 and 140 kV may have energy separation comparable to 100/140 kV and 80/140 kV dual-kV imaging. The effects of IR on CNR and NPS require further investigation for SDCT. Author YY and AD are Philips Healthcare employees.

As a product of graphic, a poster hav found its own place in many art movements and that’s why one should have the same concern for it as for others in the aspects of design and artistic view. The most important target of a commercial or advertisement is to reach the exact target audience at the exact time. Poster from its very begining, has became an area that needs a speciality in appliyng. Poster design aims to leave the neccessary effect whether by introducing the idea/product or by directing the target audience to the idea/ product. It is for sure that while moving the target audience to the aimed idea/ product, it is more easily-remembered using the popular cultural ıbjects which have a profound effect on the target audıence. Popular culture is mass culture. It is aimed to move the massive population by using the popular people, products and etc. In fact popular culture is a society to burden the creatvity and prodcution. It also a reason to resemble the society each other and it is a unit of constant changing. It is a consumption society in another saying. It supports consumption. In poster designs, it can be seen that designs are done under the effect of these popular culture. It is via this poiciy that consumers are directed to the target message or product.

    Lung inflation and respiratory motion during chest CT affect diagnostic accuracy and reproducibility. To describe a simple volume-monitored (VM) method for performing reproducible, motion-free full inspiratory and end expiratory chest CT examinations in children. Fifty-two children with cystic fibrosis (mean age 8.8 {+-} 2.2 years) underwent pulmonary function tests and inspiratory and expiratory VM-CT scans (1.25-mm slices, 80-120 kVp, 16-40 mAs) according to an IRB-approved protocol. The VM-CT technique utilizes instruction from a respiratory therapist, a portable spirometer and real-time documentation of lung volume on a computer. CT image quality was evaluated for achievement of targeted lung-volume levels and for respiratory motion. Children achieved 95% of vital capacity during full inspiratory imaging. For end expiratory scans, 92% were at or below the child's end expiratory level. Two expiratory exams were judged to be at suboptimal volumes. Two inspiratory (4%) and three expiratory (6%) exams showed respiratory motion. Overall, 94% of scans were performed at optimal volumes without respiratory motion. The VM-CT technique is a simple, feasible method in children as young as 4 years to achieve reproducible high-quality full inspiratory and end expiratory lung CT images. (orig.)

  12. Popular culture and the "new human condition": Catastrophe narratives and climate change

    Science.gov (United States)

    Bulfin, Ailise

    2017-09-01

    Striking popular culture images of burnt landscapes, tidal waves and ice-bound cities have the potential to dramatically and emotively convey the dangers of climate change. Given that a significant number of people derive a substantial proportion of their information on the threat of climate change, or the "new human condition", from popular culture works such as catastrophe movies, it is important that an investigation into the nature of the representations produced be embedded in the attempt to address the issue. What climate change-related messages may be encoded in popular films, television and novels, how are they being received, and what effects may they have? This article adopts the cultural studies perspective that popular culture gives us an important means by which to access the "structures of feeling" that characterise a society at a particular historic juncture: the views held and emotional states experienced by significant amounts of people as evident in disparate forms of cultural production. It further adopts the related viewpoint that popular culture has an effect upon the society in which it is consumed, as well as reflecting that society's desires and concerns - although the nature of the effect may be difficult to quantify. From this position, the article puts forward a theory on the role of ecological catastrophe narratives in current popular culture, before going on to review existing critical work on ecologically-charged popular films and novels which attempts to assess their effects on their audiences. It also suggests areas for future research, such as the prevalent but little studied theme of natural and environmental disaster in late-Victorian science fiction writing. This latter area is of interest because it reveals the emergence of an ecological awareness or structure of feeling as early as the late-nineteenth century, and allows the relationship of this development to environmental policy making to be investigated because of the

    2016-03-01

    Does a combination of lifestyle pressures and personality, as reflected in genre, lead to the early death of popular musicians? We explored overall mortality, cause of death, and changes in patterns of death over time and by music genre membership in popular musicians who died between 1950 and 2014. The death records of 13,195 popular musicians were coded for age and year of death, cause of death, gender, and music genre. Musician death statistics were compared with age-matched deaths in the US population using actuarial methods. Although the common perception is of a glamorous, free-wheeling lifestyle for this occupational group, the figures tell a very different story. Results showed that popular musicians have shortened life expectancy compared with comparable general populations. Results showed excess mortality from violent deaths (suicide, homicide, accidental death, including vehicular deaths and drug overdoses) and liver disease for each age group studied compared with population mortality patterns. These excess deaths were highest for the under-25-year age group and reduced chronologically thereafter. Overall mortality rates were twice as high compared with the population when averaged over the whole age range. Mortality impacts differed by music genre. In particular, excess suicides and liver-related disease were observed in country, metal, and rock musicians; excess homicides were observed in 6 of the 14 genres, in particular hip hop and rap musicians. For accidental death, actual deaths significantly exceeded expected deaths for country, folk, jazz, metal, pop, punk, and rock.

La apelación directa a la ciudadanía parece cada día más de moda en la región, cuestión que muchos autores ven como la utilización de recursos institucionales por parte de las autoridades para avanzar en una determinada agenda política. Sin embargo, la democracia directa es más heterogénea de lo que estos autores conceden. Los mismos resultados de las votaciones populares son, en términos generales, más ajustados de lo que se presupondría. La evidencia muestra que cuando los movimientos de democracia directa son utilizados por los ejecutivos, en América Latina, la tasa de aprobación no supera el 55%, incluso menor a la tasa de aprobación de cuando los inicia la ciudadanía (56%. Esto no significa que, en algunas oportunidades, las autoridades no los usen como ejercicios de movilización popular o que sean una búsqueda de legitimización popular de los deseos de las elites políticas en turno.This study examines the different ways in which citizens decide directly at the polls on topics of their concern. The direct appeal to the citizenry seems to be increasingly popular in the region and many authors do not see in it more than the use of institutional resources by the authorities to advance a particular political agenda. However, direct democracy is a much more heterogeneous phenomenon than these authors usually grant. In fact, the results of popular votes are generally much tighter than one might assume. Surprisingly, the evidence shows that when used by government agents in Latin America, the rate acceptance does not exceed 55%, even lower than the rate of approval when they are initiated by citizens (56%. This does not mean that, on occasions, authorities use them as exercises of popular mobilization or as tools seeking popular legitimization of the desires of political elites.

    Perceived popularity is associated with both positive and negative characteristics, and adolescents' stereotypes associated with popularity reflect this paradox. The current study investigated adolescents' stereotypes associated with popularity and gender, as well as their liking for popular peers who engage in prosocial, antisocial, and…

  2. Popular Science: Introductory Physics Textbooks for Home Economics Students

    2014-03-01

    For many decades now there has been an ongoing debate about the way and extent to which physics ought to be popularized by appealing to a student's every day experience. Part of this debate has focused on how textbooks, a major factor shaping students' education, ought to be written and presented. I examine the background, passages, and problems of two examples drawn from the special genre of ``Household Physics'' textbooks which were published largely between 1910 and 1940. The pedagogy of applying or relating physics to the everyday experience engenders values defining how and by whom science is to be applied. These books are particularly evocative, as well, of the extent to which gender can be tied to differing everyday experiences and the consequences therefore of using experiential examples. Using popular science textbooks can alienate students by drawing an implicit division between the reader and the practicing scientist.

  3. Rewriting the Salem Witchcraft Trials in Contemporary Popular Literature

    2016-10-01

    Full Text Available The Salem Witchcraft Trials (1692 have received a lot of attention from history and literature, although there are very few critical analysis of how this historical event has entered the literary field. Many works of historical fiction – considered the most suitable literary genre to talk about an historical event - have used it in their storylines; however, popular genres such as romance, crime fiction, fantasy and science fiction have also shown an interest in this witch hunt. The main reason for this interest can be found in the lack of final conclusions as regards what really happened in Salem. The main objective of this paper is to show how what happened in Salem has entered contemporary popular fiction with the aim of showing the interest that it still arises and to vindicate the production of more critical works about the literary construction of one of the events that most dramatically has affected the configuration of the American mind.

  4. Popular Orientalism: Somerset Maugham in Mainland Southeast Asia

    Directory of Open Access Journals (Sweden)

    Christine Doran

    2016-02-01

    Full Text Available Based on his experiences during a journey through mainland Southeast Asia in 1923, Somerset Maugham wrote a book of colonial travel entitled The Gentleman in the Parlour. As the work of one of the most popular writers of the twentieth century, Maugham’s travelogue both expressed and helped to shape contemporary thinking about Southeast Asia and Western imperialism. Focusing especially on his representations of Burma and Cambodia, an analysis is presented of Maugham’s book in the light of postcolonial scholarship, especially the theoretical insights developed under the inspiration of Edward Said’s Orientalism. Despite its pretensions to be apolitical, Maugham’s travel book is shown to be a repository of Western colonial ideas and attitudes, integrally involved in the circulation of the prevailing European discourse of high imperialism. As such, it is a valuable resource for historians and other scholars who wish to understand the way that discourse worked at the level of popular literature.

  5. Popular Geopolitics of Japan: Geopolitical Discourses of Anime

    Marta Zorko

    2014-12-01

    Full Text Available Geopolitical discourses are an integral part of the contemporary geopolitics of each state. Driven by geopolitical traditions and imagination, they intercept and thus create all aspects of the discipline of critical geopolitics- the formal, practical and popular. The main area of our research is the discourse embedded in the popular geopolitics of a specific cultural product of Japan, anime. Anime are unique and thus suited for analysis for two reasons. The first is their specific, local production and global recognition. The second is their double coding. Although they are a product of the traditional geopolitical culture of Japan’s entertainment industry, they are able to create a contemporary geopolitical culture at the same time. Through an analysis of three anime series, Tokyo Magnitude 8.0, Earth Maiden Arjuna and Mobile Suit Gundam 00, we explore the geographic and geopolitical characteristics of Japan and their influence on the traditional, as well as the contemporary geopolitical discourses.

  6. Feature Driven and Point Process Approaches for Popularity Prediction

    2016-01-01

    Predicting popularity, or the total volume of information outbreaks, is an important subproblem for understanding collective behavior in networks. Each of the two main types of recent approaches to the problem, feature-driven and generative models, have desired qualities and clear limitations. This paper bridges the gap between these solutions with a new hybrid approach and a new performance benchmark. We model each social cascade with a marked Hawkes self-exciting point process, and estimate the content virality, memory decay, and user influence. We then learn a predictive layer for popularity prediction using a collection of cascade history. To our surprise, Hawkes process with a predictive overlay outperform recent feature-driven and generative approaches on existing tweet data [43] and a new public benchmark on news tweets. We also found that a basic set of user features and event time summary statistics performs competitively in both classification and regression tasks, and that adding point process info...

    Nowadays, myths and superstitions are present in spite of scientific and technological developments, especially when trying to solve problems that escape human understanding. This study was aimed at determining the existence of superstitions and myths in the university community, investigating their origins, influences, adoption and credibility, correlating them with people's level of knowledge. It is a descriptive/analytical research conducted at Teaching Units in the Area of Health of the Federal University of Goiás. The technique of content analysis was utilized for data analysis. Two categories have been created: Personal Attitudes related to Superstitions and Influences and Destruction of Superstitions. It was found out that there is a clash between popular and scientific knowledge, either leading to the exclusion of popular wisdom, to its 'veiled' maintenance, or even to an alliance between the two types of knowledge.

  8. Multimodal representations of gender in young children's popular culture

    Directory of Open Access Journals (Sweden)

    Fredrik Lindstrand

    2016-12-01

    Full Text Available This article poses questions regarding learning and representation in relation to young children's popular culture. Focusing on gender, the article builds on multimodal, social semiotic analyses of two different media texts related to a specific brand and shows how gender and gender differences are represented multimodally in separate media contexts and in the interplay between different media. The results show that most of the semiotic resources employed in the different texts contribute in congruent ways to the representation of girls as either different from or inferior to boys. At the same time, however, excerpts from an encounter with a young girl who engages with characters from the brand in her role play are used as an example of how children actively make meaning and find strategies that subvert the repressive ideologies manifested in their everyday popular culture.

  9. Policiais e populares: educadores, educandos e a higiene social

    Valter Martins

    Full Text Available O insalubre Largo do Jurumbeval, em Campinas, constituiu durante a segunda metade do século XIX importante espaço de trabalho, diversão e moradia popular. A promíscua aglomeração de pessoas: escravos, libertos, imigrantes e nacionais pobres, inquietava as autoridades que, por meio da ação da polícia, procuravam limitar, controlar e ordenar os movimentos de pessoas vistas como perigosas à sociedade, por seu comportamento considerado imoral e escandaloso. Nessa tentativa de realizar uma higiene social, por vezes, a própria polícia acabava representando um papel ambíguo, ao praticar os mesmos atos que devia reprimir. Resgatar alguns momentos dessa "didática" policial na vida das classes populares constitui o objetivo deste artigo.

    2016-03-01

    Full Text Available Scientific discourse produced by and for specialists reaches, by means of science popularization (SP, the public sphere of the media, envolving displacements in time, space, and discourse. This hybridization between science and journalism generates scientific journalism, which aims at popularizing science and making it comprehensible, thus performing a pedagogical function. We consider this process as discourse recontextualization from the scientific to the journalistic spheres, mediated by a pedagogic discourse. We argue, in this paper, that SP news texts and scientific articles are members of the same genre system that makes scientific discourse relatively visible to the general public. Firstly, we identify our theoretical framework, the concept we adopt for SP, genre system and recontextualization. Secondly, we explore interdiscursivity in one exemplar of the SP news genre, highlighting the existing relations between science, journalism, and pedagogy in this genre.

    Popular music is a key cultural expression that has captured listeners' attention for ages. Many of the structural regularities underlying musical discourse are yet to be discovered and, accordingly, their historical evolution remains formally unknown. Here we unveil a number of patterns and metrics characterizing the generic usage of primary musical facets such as pitch, timbre, and loudness in contemporary western popular music. Many of these patterns and metrics have been consistently stable for a period of more than fifty years. However, we prove important changes or trends related to the restriction of pitch transitions, the homogenization of the timbral palette, and the growing loudness levels. This suggests that our perception of the new would be rooted on these changing characteristics. Hence, an old tune could perfectly sound novel and fashionable, provided that it consisted of common harmonic progressions, changed the instrumentation, and increased the average loudness.

  12. Can electoral popularity be predicted using socially generated big data?

    2013-01-01

    Today, our more-than-ever digital lives leave significant footprints in cyberspace. Large scale collections of these socially generated footprints, often known as big data, could help us to re-investigate different aspects of our social collective behaviour in a quantitative framework. In this contribution we discuss one such possibility: the monitoring and predicting of popularity dynamics of candidates and parties through the analysis of socially generated transactional data on the web during electoral campaigns. We focus on two data streams, Wikipedia page views and Google search queries, and discuss issues related to data collection, data cleaning, data analysis as well as the expressiveness and representativeness of the data; we also present popularity dynamics from real case examples of recent elections in three different countries.

  13. Construction and communication of meanings in popular music

    Directory of Open Access Journals (Sweden)

    Julián Céspedes Guevara

    2010-11-01

    Full Text Available Both musicology and the psychology of music have traditionally approached the construction and communication of musical meanings using a functionalist model of communication. The purpose of this research is to study these phenomena within the context of popular music, using a constructivist theoretical framework. Two songs from a funk-rock band and 2 songs from a jazz band were heard individually by 6 members of the bands and by 14 participants without formal musical training. The participants were asked to indicate the moments in which the music called their attention, and to elaborate on the meaning of each song. The findings were interpreted as evidence that musical meaning is not inherent to music, that popular music is not always perceived an expression of emotions, and that musical communication depends on the existence of shared symbolic referents by musicians and listeners. As a conclusion, a constructivist conceptual model of musical communication is proposed

  14. Japanese Martial Arts as Popular Culture: Teaching Opportunity and Challenge

    Directory of Open Access Journals (Sweden)

    Stephen Robert NAGY

    2015-07-01

    Full Text Available Japanese martial arts, here after Japanese budō, are popular cultural icons that are found in films, comics, video games and books. Teaching Japanese budō at university offers a novel way to teach about East Asian and in particular Japanese culture, history, and philosophy while including ideas about the globalization and the localization of culture. Question though remains as to how and what should we teach about the popular culture of Japanese budō at the university level? This paper found that a comprehensive approach to teaching about budō was effective. By using many kinds of materials and the incorporation of opportunities to experience budō and to try budō, students were better able to grasp the historical, cultural and religious characteristics of budō.

    Full Text Available There is no gainsaying that most of the recent forms of contemporary popular music produced, packaged, made available for public consumption constitute grave danger and serious threat to moral uprightness in Nigerian society. This has exposed the Nigerian society to a wide variety of insecurity and violence. This is evident as seen from series of moral decadence and dissipation that infiltrated the lives of the citizenry - especially the youths (the leaders of tomorrow ranging from, sexual abuse, money mongering, indiscipline, examination malpractice and indecent dressing to mention but a few. Music is a powerful tool and a force for mobilization which brings about either reformation or deformation of character due to the type of rhythm, melody, harmony and principally the lyrics of the songs. This paper examines the new trend of contemporary popular music in Nigeria with a view to assess its negative and pessimistic impacts on the character molding of the citizenry in Nigerian society. Live performances of contemporary popular music were observed and audio and video tape materials relating to the said music were also analyzed based on their educational  and moral values of such songs. It was  discovered that contemporary popular music as we have it today in Nigeria communicates vulgarity and coarseness to the listeners and this poses a lot of negative effects on the attitude of the youths. Musicians employ indecent words to attract the youth thus creating negative influence on the character of the leaders of tomorrow (the youth to engage in various   debauchery.  The paper therefore, suggested that relevant agencies should be put in place to ensure that apart from entertainment, music should convey positive character building messages rather than music that egg on and motivate illicit acts. Likewise, musicians should compose songs in the spirit of societal reformation so as to impact moral virtues on the younger generation  thus

    2007-05-01

    In our days the scientific popularization in Mexico has not a promising future and with the earth sciences is not better; most of the papers in the popularization magazines deal with subjects as earthquakes, volcanoes, plate tectonics, meteorite impacts and the massive extensions associated with them (e.g. Chicxulub). However, these subjects have not been enough to create conscience about the importance of earth sciences in the society and it has even motivated the idea of a community distant scientific with no social obligation, the idea that the earth scientists are responsible for all the problems in the planet (global warming, catastrophes) is wide spread. In these days that we need a change in our consumption, mainly in the energetic one, it's compulsory to change the relation between the subject and its environment; then, as we can not take care of something that we don't know, the scientific popularization has a fundamental role that we must start to pay attention to.

    2014-03-01

    The homicide statistics of a popular UK television fictional crime series and the former Lothian & Borders police force region, Scotland were compared. This comparison was used to consider the implications for public attitudes which may influence the adoption of public health interventions to reduce homicide. 217 homicides were identified by 105 perpetrators in the television series 'Midsomer Murders' between 1997 and 2011; these were compared to 55 homicides by 53 perpetrators in the regional sample between 2006 and 2011. The numbers of serial killings (p < 0.0001), planned homicides, female perpetrators (p < 0.0001), shootings (p = 0.0456) and poisonings (p = 0.0289) were higher in the fictional sample. Lothian & Borders cases were almost all single killings, mostly unplanned, with a far greater rate of homicide by kitchen knives (p < 0.0001) and hitting/kicking (p = 0.0005) by intoxicated perpetrators. Control of access to pointed kitchen knives by members of certain groups may reduce homicide rates. If the popular perception of UK homicides is influenced by popular culture, the importance of such a public health intervention may not be apparent.

    2015-12-01

    This paper presents an algorithm providing recommendations for optimizing the LHCb data storage. The LHCb data storage system is a hybrid system. All datasets are kept as archives on magnetic tapes. The most popular datasets are kept on disks. The algorithm takes the dataset usage history and metadata (size, type, configuration etc.) to generate a recommendation report. This article presents how we use machine learning algorithms to predict future data popularity. Using these predictions it is possible to estimate which datasets should be removed from disk. We use regression algorithms and time series analysis to find the optimal number of replicas for datasets that are kept on disk. Based on the data popularity and the number of replicas optimization, the algorithm minimizes a loss function to find the optimal data distribution. The loss function represents all requirements for data distribution in the data storage system. We demonstrate how our algorithm helps to save disk space and to reduce waiting times for jobs using this data.

  9. Teaching ethics using popular songs: feeling and thinking.

    Science.gov (United States)

    O'Mathúna, Dónal P

    2008-01-01

    A connection has long been made between music and moral education. Recent discussions have focused on concerns that certain lyrics can lead to acceptance of violence, suicide, inappropriate views of women, and other unethical behaviour. Debate over whether such connections exist at least illustrates that popular songs engage listeners with ethical issues; this arises from the unique blend of emotional and cognitive reactions to music. And while the emotional side of ethics has received less attention than other aspects of ethics, it is important and music can be a powerful and unique tool to introduce the emotional aspects of ethics. Music appeals to almost everyone. Throughout history songs have rallied people to action and drawn people into deeper reflection. Music engages our emotions, our imagination and our intellect. Students already spend many hours listening to songs, some of which address ethical issues; it is thus an ideal pedagogic aid in teaching subjects like ethics. This article will discuss how carefully selected songs can encourage thoughtful reflection and critical thinking about ethical issues: a number of specific examples will be described, along with a discussion of the general practicalities of using popular songs in teaching ethics and a demonstration of how students learn to listen critically and actively reflect on the ethical messages they receive. The enjoyment of music helps to engage students with ethics and its relevance for their lives and careers. This article aims to share some of the excitement and enthusiasm that popular songs have brought to my teaching of ethics.

  12. Organizing Science Popularization and Teacher Training Workshops : A Nigerian Experience

    Science.gov (United States)

    Okpala, Kingsley; Okere, Bonaventure

    Funding for science popularization has become a huge challenge in recent times especially for developing countries like Nigeria. However, a change in the school system from the 6-3-3-4 system (6 years primary, 3 years Junior secondary, 3year senior secondary, and 4 years tertiary education) to the 9-3-4 system ( 9 years junior basic, 3 years secondary, and 4 tertiary education) has made it even more convenient to strategically target the students through their teachers to attain the desired quality of education since the introduction of space science into the curriculum at the primary and secondary levels. Considering the size of Nigeria, there Is need for a shift in paradigm for sourcing resources to tackle this deficiency in a sustainable manner. Recently a teacher training and science popularization workshop was organized as a first in a series of subsequent workshops geared towards having a sustainable means of popularizing Science in Nigeria. Principally, the key lies in the partnership with the colleges of education which produce the teachers for primary schools in addition to the usual governmental actions. Experiences from this workshop will be enumerated with the hope of inspiring the same success in similar societies.

  13. Rimas para juegos infantiles en el antiguo cancionero popular

    Directory of Open Access Journals (Sweden)

    Margit Frenk

    2013-01-01

    Full Text Available Al estudiar los rasgos formales y estilísticos de las "canciones escenificadas" que se conservan en las fuentes del Siglo de Oro, comprobamos que algunas de estas rimas que acompañaban los juegos infantiles parecen tener las mismas características. Además, estas canciones presentan, formal y estructuralmente, ciertos rasgos que las diferencian de otras composiciones de la antigua lírica popular de la Península Ibérica. En general, estas canciones escenificadas son más extensas y presentan una constante irregularidad métrica y formal, lo que las sitúa al margen de lo que conocemos como "antigua lírica popular". Estas diferencias formales y estructurales revelan que las "canciones escenificadas", al no haber pasado por el tamiz de la literatura culta -como sí ha sucedido con muchas composiciones de la antigua lírica popular - mantienen su carácter claramente tradicional y son más cercanas al folclore contemporáneo.

    2011-12-01

    Full Text Available Science popularization is demanding from the financial as well as the time point of view. It is necessary to find the premises that would be easily available to general public. Another important step is to promote the event so that it would attract the audience. The preparation of scientific experiments itself also requires some financial resources. If we want to take advantage of these resources in the most useful and effective way, we have to find answers to the question: “What, where and how do we want to popularise?” In the paper, we describe one-day project aimed to popularization of scientific fields carried out by eight departments of the Faculty of Natural Sciences, Constantine the Philosopher University in Nitra. The project was named Scientific Fair – Science you can see, hear and experience. Its main goal was to present seven scientific fields - Physics, Informatics, Mathematics, Geography, Ecology, Chemistry and Biology. Popularization was carried out as experimental interactive activities unveiling the undisclosed corners of science. Their aim was to inspire the audience, arouse their interest in science and motivate the participants to cognitive activities. We introduce the idea of the project in detail concentrating mainly on informatics realized by the Department of Informatics.

    Full Text Available This article deals with illustrations in popularizing medical discourse. This visual tool can be considered as a strategy of paraphrasing, since popularizing journalists simplify and make information more explicit by using other semiotic information related to the main scientific content. A comparable corpus composed of the online versions of two American, two French and two Italian magazines of science popularization has been analysed. The role of illustrations, as well as their usefulness in terms of comprehension of the text, has been highlighted through a socio-terminological approach (Gaudin 2003. As far as a typological distinction of the illustrations is concerned, a Peircean classification has been adopted (Fisette 2009; Lathene-Da Cunha 2013. A number of observations emerge from the comparison between the magazines, per type and per language: the article shows that, while some illustrations contribute to a better intelligibility of the article’s content, others influence readers’ sensitivity.

  16. People and the Popular, Culture and the Cultural

    Full Text Available ‘Popular’, ‘culture’ and ‘folk’ are discussed by Raymond Williams as highly charged keywords: semantically, historically and from the point of view of the various areas of research which have adopted them in their denominations. The elusive character of these terms is reflected in the many problems we encounter when exploring the field of popular culture studies. In particular, since the 1980s, neo-Marxist cultural studies historians have claimed the label of ‘popular culture’ for the sole study of post-industrial commercial phenomena. This exclusive identification and the comparative disregard of research on pre-industrial popular cultures has become a doxa in the so called ‘cultural studies approach’ and has also affected the field of Shakespearean studies, where ‘popular’ is almost exclusively connected with the ‘afterlife’ of Shakespeare’s plays and their appropriation by the modern media. This article discusses what has been considered an ‘elision of the past’ performed in many recent studies, at the same time suggesting that socio-historical research on the pre-industrial and pre-commercial culture of ‘the people’ implies the reading of entirely different ‘texts’ and their different mode of transmission than the study of modern and late modern manifestations of ‘popular’ commercial products and their reception; and that, therefore, it requires the adoption of entirely different paradigms and methods of analysis.

    2015-01-01

    Background Mobile phone apps have the potential to reduce excessive alcohol consumption cost-effectively. Although hundreds of alcohol-related apps are available, there is little information about the behavior change techniques (BCTs) they contain, or the extent to which they are based on evidence or theory and how this relates to their popularity and user ratings. Objective Our aim was to assess the proportion of popular alcohol-related apps available in the United Kingdom that focus on alcohol reduction, identify the BCTs they contain, and explore whether BCTs or the mention of theory or evidence is associated with app popularity and user ratings. Methods We searched the iTunes and Google Play stores with the terms “alcohol” and “drink”, and the first 800 results were classified into alcohol reduction, entertainment, or blood alcohol content measurement. Of those classified as alcohol reduction, all free apps and the top 10 paid apps were coded for BCTs and for reference to evidence or theory. Measures of popularity and user ratings were extracted. Results Of the 800 apps identified, 662 were unique. Of these, 13.7% (91/662) were classified as alcohol reduction (95% CI 11.3-16.6), 53.9% (357/662) entertainment (95% CI 50.1-57.7), 18.9% (125/662) blood alcohol content measurement (95% CI 16.1-22.0) and 13.4% (89/662) other (95% CI 11.1-16.3). The 51 free alcohol reduction apps and the top 10 paid apps contained a mean of 3.6 BCTs (SD 3.4), with approximately 12% (7/61) not including any BCTs. The BCTs used most often were “facilitate self-recording” (54%, 33/61), “provide information on consequences of excessive alcohol use and drinking cessation” (43%, 26/61), “provide feedback on performance” (41%, 25/61), “give options for additional and later support” (25%, 15/61) and “offer/direct towards appropriate written materials” (23%, 14/61). These apps also rarely included any of the 22 BCTs frequently used in other health behavior change

    Full Text Available Science education and popularization of science are important elements for social inclusion. The Brazil exhibits strong inequalities regarding the distribution of wealth, access to cultural assets and appropriation of scientific and technological knowledge. Each Brazilian should have the opportunity to acquire a basic knowledge of science and its operation that allow them to understand their environment and expand their professional opportunities. However, the overall performance of Brazilian students in science and math is bad. The basic science education has, most often, few resources and is discouraging, with little appreciation of experimentation, interdisciplinarity and creativity. Beside the shortage of science teachers, especially teachers with good formation, predominate poor wage and working conditions, and deficiencies in instructional materials and laboratories. If there was a significant expansion in access to basic education, the challenge remains to improve their quality. According to the last National Conference of STI, there is need of a profound educational reform at all levels, in particular with regard to science education. Already, the popularization of science can be an important tool for the construction of scientific culture and refinement of the formal teaching instrument. However, we still lack a comprehensive and adequate public policy to her intended. Clearly, in recent decades, an increase in scientific publication occurred: creating science centers and museums; greater media presence; use of the internet and social networks; outreach events, such as the National Week of CT. But the scenario is shown still fragile and limited to broad swathes of Brazilians without access to scientific education and qualified information on CT. In this presentation, from a general diagnosis of the situation, some of the main challenges related to education and popularization of science in the country will address herself.

    Food and beverage marketing has been associated with childhood obesity. We quantified the number and type of food or beverage brands promoted by music celebrities, assessed the nutritional quality of the products, and examined Teen Choice Award data to assess the celebrities' popularity among adolescents. This was a descriptive study. A list of music celebrities associated with the 2013 and 2014 Billboard Hot 100 Chart, which ranks songs according to sales and radio impressions, was compiled. Data on celebrity endorsements were gathered from official company Web sites, YouTube commercials, an advertising database, and media reports. Nutritional quality of foods was assessed according to the Nutrient Profile Index, whereas nonalcoholic beverages were evaluated based on calories from added sugar. Teen Choice Award nominations were used to measure the celebrities' popularity among adolescents. Of the 590 endorsements made by the 163 celebrities in the sample, consumer goods (eg, fragrances, makeup) represented the largest endorsement category (26%), followed by food and beverage (18%) and retail (11%). Sixty-five celebrities were collectively associated with 57 different food and beverage brands owned by 38 parent companies. Of these 65 celebrities, 53 (81.5%) had ≥1 Teen Choice Award nomination. Forty-nine (71%) of the 69 nonalcoholic beverage references promoted sugar-sweetened beverages. Twenty-one (80.8%) of the 26 endorsed foods were energy dense and nutrient poor. Baauer, will.i.am, Justin Timberlake, Maroon 5, and Britney Spears had the most food and beverage endorsements. This study demonstrates that music celebrities who are popular among adolescents endorse energy-dense, nutrient-poor products. Copyright © 2016 by the American Academy of Pediatrics.

    Full Text Available Este artículo busca plantear una reflexión pedagógica sobre la popularización de la ciencia y la tecnología, desde una perspectiva crítica feminista. Inicialmente presenta cómo la popularización se ha centrado en promover una imagen del conocimiento científico tecnológico anclada en paradigmas androcéntricos, desde los que no se cuestiona el estatuto epistemológico de estos conocimientos ni las subjetividades que desde allí se promueven. Propone retomar algunos de los planteamientos de la educación popular, que pueden ser de utilidad para repensar educativamente la popularización de la ciencia y la tecnología. Particularmente hace énfasis en la importancia y necesidad de rescatar la dimensión ético y política de lo popular en la concepción pedagógica de la popularización con el objetivo de fortalecer sus potencialidades críticas. En relación a esto argumenta, retomando la pedagogía feminista, especialmente aquella que se apoya en los enfoques sobre el conocimiento situado, como son las que derivan de los feminismos de frontera o decoloniales, que una lectura feminista de lo propuesto por Freire, es decir, que reconozca el papel de las experiencias de vida de hombres y mujeres popularizadores de la ciencia y la tecnología en la puesta en escena de estas prácticas educativas, puede enriquecer la legitimación ético-política-epistemológica de lo popular en una idea de popularización como práctica educativa transformadora.This article aims to contribute, from a feminist critical perspective, to the pedagogical reflection about the popularization of science and technology.

    It has been shown recently that in many different cultural phenomena the turnover rate on the most popular artefacts in a population exhibit some regularities. A very simple expression for this turnover rate has been proposed by Bentley et al. and its validity in two simple models for copying and innovation is investigated in this paper. It is found that Bentley's formula is an approximation of the real behaviour of the turnover rate in the Wright-Fisher model, while it is not valid in the Moran model.

    For this contribution to the special issue on "Mapping Queer Bioethics," the author undertakes the curatorial spaces of the library, the museum, the textbook, and the public exhibition. With showcases such as natural history museums and the recent Bodyworlds traveling exhibit as touchstones, the author argues that distinctions between medical and popular visual culture in pedagogical contexts are porous, such that the study of sensational body types (queer, anatomically atypical, and otherwise) are couched in culturally problematic appreciations of the agency of certain bodies to speak for and/or about themselves. By extension, how and where certain bodies are viewed represent vital, bioethical dilemmas on the nature of corporeal viability.

With more than two-thirds of the U.S. population overweight or obese, and research showing that one-third are on a diet at any given time, a need existed to determine whether current popular diet plans could protect followers from micronutrient deficiency by providing the minimum levels of 27 micronutrients, as determined by the U.S. Food and Drug Administrations (FDA Reference Daily Intake (RDI guidelines. Methods Suggested daily menus from four popular diet plans (Atkins for Life diet, The South Beach Diet, the DASH diet, the DASH diet were evaluated. Calorie and micronutrient content of each ingredient, in each meal, were determined by using food composition data from the U.S. Department of Agriculture Nutrient Database for Standard Reference. The results were evaluated for sufficiency and total calories and deficient micronutrients were identified. The diet plans that did not meet 100% sufficiency by RDI guidelines for each of the 27 micronutrients were re-analyzed; (1 to identify a micronutrient sufficient calorie intake for all 27 micronutrients, and (2 to identify a second micronutrient sufficient calorie intake when consistently low or nonexistent micronutrients were removed from the sufficiency requirement. Results Analysis determined that each of the four popular diet plans failed to provide minimum RDI sufficiency for all 27 micronutrients analyzed. The four diet plans, on average, were found to be RDI sufficient in (11.75 ± 2.02; mean ± SEM of the analyzed 27 micronutrients and contain (1748.25 ± 209.57 kcal. Further analysis of the four diets found that an average calorie intake of (27,575 ± 4660.72 would be required to achieve sufficiency in all 27 micronutrients.
