Taking observations as operations based on distinction and indication (selection) contingency becomes a fundamental condition in learning......  Abstract The aim of this paper is to discuss the relation between teaching and learning. The point of departure is that teaching environments (communication forums) is a potential facilitator for learning processes and knowledge construction. The paper present a theoretical frame work, to discuss...... processes, and a condition which teaching must address as far as teaching strives to stimulate non-random learning outcomes. Thus learning outcomes understood as the individual learner's knowledge construction cannot be directly predicted from events and characteristics in the environment. This has...

    Electroactive polymers (EAP) are human made actuators that are the closest to mimic biological muscles. Technology was advanced to the level that biologically inspired robots are taking increasing roles in the world around us and making science fiction ideas a closer engineering reality. Artificial technologies (AI, AM, and others) are increasingly becoming practical tools for making biologically inspired devices and instruments with enormous potential for space applications. Polymer materials are used to produce figures that resemble human and animals. These materials are widely employed by the movie industry for making acting figures and by the orthopedic industry to construct cyborg components. There are still many challenges ahead that are critical to making such possibilities practical. The annual armwrestling contest is providing an exciting measure of how well advances in EAP are implemented to address the field challenges. There is a need to document natures inventions in an engineering form to possibly inspire new capabilities.

  5. Long-term knowledge acquisition using contextual information in a memory-inspired robot architecture

    2017-03-01

    In this paper, we present a novel cognitive framework allowing a robot to form memories of relevant traits of its perceptions and to recall them when necessary. The framework is based on two main principles: on the one hand, we propose an architecture inspired by current knowledge in human memory organisation; on the other hand, we integrate such an architecture with the notion of context, which is used to modulate the knowledge acquisition process when consolidating memories and forming new ones, as well as with the notion of familiarity, which is employed to retrieve proper memories given relevant cues. Although much research has been carried out, which exploits Machine Learning approaches to provide robots with internal models of their environment (including objects and occurring events therein), we argue that such approaches may not be the right direction to follow if a long-term, continuous knowledge acquisition is to be achieved. As a case study scenario, we focus on both robot-environment and human-robot interaction processes. In case of robot-environment interaction, a robot performs pick and place movements using the objects in the workspace, at the same time observing their displacement on a table in front of it, and progressively forms memories defined as relevant cues (e.g. colour, shape or relative position) in a context-aware fashion. As far as human-robot interaction is concerned, the robot can recall specific snapshots representing past events using both sensory information and contextual cues upon request by humans.

    In a static monocular camera system, to gain a perfect 3D human body posture is a great challenge for Computer Vision technology now. This paper presented human postures recognition from video sequences using the Quantum-Inspired Immune Cloning Algorithm (QICA). The algorithm included three parts. Firstly, prior knowledge of human beings was used, the key joint points of human could be detected automatically from the human contours and skeletons which could be thinning from the contours; And due to the complexity of human movement, a forecasting mechanism of occlusion joint points was addressed to get optimum 2D key joint points of human body; And then pose estimation recovered by optimizing between the 2D projection of 3D human key joint points and 2D detection key joint points using QICA, which recovered the movement of human body perfectly, because this algorithm could acquire not only the global optimal solution, but the local optimal solution.

    Effortless control of the human hand is mediated by the physical and neural couplings inherent in the structure of the hand. This concept was explored for environmental interaction tasks with the human hand, and a novel human-inspired feedback synergy (HFS) controller was developed for a robotic hand which synchronized position and force feedback signals to mimic observed human hand motions. This was achieved by first recording the finger joint motion profiles of human test subjects, where it was observed that the subjects would extend their fingers to maintain a natural hand posture when interacting with different surfaces. The resulting human joint angle data were used as inspiration to develop the HFS controller for the anthropomorphic robotic hand, which incorporated finger abduction and force feedback in the control laws for finger extension. Experimental results showed that by projecting a broader view of the tasks at hand to each specific joint, the HFS controller produced hand motion profiles that closely mimic the observed human responses and allowed the robotic manipulator to interact with the surfaces while maintaining a natural hand posture. Additionally, the HFS controller enabled the robotic hand to autonomously traverse vertical step discontinuities without prior knowledge of the environment, visual feedback, or traditional trajectory planning techniques.

    This paper discusses the concept of ageing as this applies to the operation of Evolutionary Algorithms, and examines its relationship to the concept of ageing as this is understood for human beings. Evolutionary Algorithms constitute a family of search algorithms which base their operation on an analogy from the evolution of species in nature. The paper initially provides the necessary knowledge on the operation of Evolutionary Algorithms, focusing on the use of ageing strategies during the implementation of the evolutionary process. Background knowledge on the concept of ageing, as this is defined scientifically for biological systems, is subsequently presented. Based on this information, the paper provides a comparison between the two ageing concepts, and discusses the philosophical inspirations which can be drawn for human ageing based on the operation of Evolutionary Algorithms.

  11. Human climbing with efficiently scaled gecko-inspired dry adhesives.

    Hawkes, Elliot W; Eason, Eric V; Christensen, David L; Cutkosky, Mark R

    2015-01-06

    Since the discovery of the mechanism of adhesion in geckos, many synthetic dry adhesives have been developed with desirable gecko-like properties such as reusability, directionality, self-cleaning ability, rough surface adhesion and high adhesive stress. However, fully exploiting these adhesives in practical applications at different length scales requires efficient scaling (i.e. with little loss in adhesion as area grows). Just as natural gecko adhesives have been used as a benchmark for synthetic materials, so can gecko adhesion systems provide a baseline for scaling efficiency. In the tokay gecko (Gekko gecko), a scaling power law has been reported relating the maximum shear stress σmax to the area A: σmax ∝ A(-1/4). We present a mechanical concept which improves upon the gecko's non-uniform load-sharing and results in a nearly even load distribution over multiple patches of gecko-inspired adhesive. We created a synthetic adhesion system incorporating this concept which shows efficient scaling across four orders of magnitude of area, yielding an improved scaling power law: σmax ∝ A(-1/50). Furthermore, we found that the synthetic adhesion system does not fail catastrophically when a simulated failure is induced on a portion of the adhesive. In a practical demonstration, the synthetic adhesion system enabled a 70 kg human to climb vertical glass with 140 cm(2) of adhesive per hand. © 2014 The Author(s) Published by the Royal Society.

    Full Text Available Mental image directed semantic theory (MIDST has proposed an omnisensory mental image model and its description language Lmd. This language is designed to represent and compute human intuitive knowledge of space and can provide multimedia expressions with intermediate semantic descriptions in predicate logic. It is hypothesized that such knowledge and semantic descriptions are controlled by human attention toward the world and therefore subjective to each human individual. This paper describes Lmd expression of human subjective knowledge of space and its application to aware computing in cross-media operation between linguistic and pictorial expressions as spatial language understanding.

  14. Covert leadership: notes on managing professionals. Knowledge workers respond to inspiration, not supervision.

    Mintzberg, H

    1998-01-01

    The orchestra conductor is a popular metaphor for managers today--up there on the podium in complete control. But that image may be misleading, says Henry Mintzberg, who recently spent a day with Bramwell Tovey, conductor of the Winnipeg Symphony Orchestra, in order to explore the metaphor. He found that Tovey does not operate like an absolute ruler but practices instead what Mintzberg calls covert leadership. Covert leadership means managing with a sense of nuances, constraints, and limitations. When a manager like Tovey guides an organization, he leads without seeming to, without his people being fully aware of all that he is doing. That's because in this world of professionals, a leader is not completely powerless--but neither does he have absolute control over others. As knowledge work grows in importance, the way an orchestra conductor really operates may serve as a good model for managers in a wide range of businesses. For example, Mintzberg found that Tovey does a lot more hands-on work than one might expect. More like a first-line supervisor than a hands-off executive, he takes direct and personal charge of what is getting done. In dealing with his musicians, his focus is on inspiring them, not empowering them. Like other professionals, the musicians don't need to be empowered--they're already secure in what they know and can do--but they do need to be infused with energy for the tasks at hand. This is the role of the covert leader: to act quietly and unobtrusively in order to exact not obedience but inspired performance.

    Objective. The human auditory system acquires environmental information under sound stimuli faster than visual or touch systems, which in turn, allows for faster human responses to such stimuli. It also complements senses such as sight, where direct line-of-view is necessary to identify objects, in the environment recognition process. This work focuses on implementing human reaction to sound stimuli and environment recognition on assistive robotic devices, such as robotic wheelchairs or robotized cars. These vehicles need environment information to ensure safe navigation. Approach. In the field of environment recognition, range sensors (such as LiDAR and ultrasonic systems) and artificial vision devices are widely used; however, these sensors depend on environment constraints (such as lighting variability or color of objects), and sound can provide important information for the characterization of an environment. In this work, we propose a sound-based approach to enhance the environment recognition process, mainly for cases that compromise human integrity, according to the International Classification of Functioning (ICF). Our proposal is based on a neural network implementation that is able to classify up to 15 different environments, each selected according to the ICF considerations on environment factors in the community-based physical activities of people with disabilities. Main results. The accuracy rates in environment classification ranges from 84% to 93%. This classification is later used to constrain assistive vehicle navigation in order to protect the user during daily activities. This work also includes real-time outdoor experimentation (performed on an assistive vehicle) by seven volunteers with different disabilities (but without cognitive impairment and experienced in the use of wheelchairs), statistical validation, comparison with previously published work, and a discussion section where the pros and cons of our system are evaluated.

    Humans can adapt to abruptly changing situations by coordinating redundant components, even in bipedality. Conventional adaptability has been reproduced by various computational approaches, such as optimal control, neural oscillator, and reinforcement learning; however, the adaptability in bipedal locomotion necessary for biological and social activities, such as unpredicted direction change in chase-and-escape, is unknown due to the dynamically unstable multi-link closed-loop system. Here we propose a switching adaptation model for performing bipedal locomotion by improving autonomous distributed control, where autonomous actuators interact without central control and switch the roles for propulsion, balancing, and leg swing. Our switching mobility model achieved direction change at any time using only three actuators, although it showed higher motor costs than comparable models without direction change. Our method of evaluating such adaptation at any time should be utilized as a prerequisite for understanding universal motor control. The proposed algorithm may simply explain and predict the adaptation mechanism in human bipedality to coordinate the actuator functions within and between limbs.

    Knowledge management has recently taken a more prominent role in the management of organizations as worker knowledge and intellectual capital are recognized as critical to organizational success. This analysis explores the literature of knowledge management including the individual level of tacit and explicit knowledge, the networks and social interactions utilized by workers to create and share new knowledge, and the multiple organizational and managerial factors associated with effective knowledge management systems. Based on the role of organizational culture, structure, leadership, and reward systems, six strategies are identified to assist human service organizations with implementing new knowledge management systems.

    We present a novel control approach for assistive lower-extremity exoskeletons. In particular, we implement a virtual pivot point (VPP) template model inspired leg force feedback based controller on a lower-extremity powered exoskeleton (LOPES II) and demonstrate that it can effectively assist humans during walking. It has been shown that the VPP template model is capable of stabilizing the trunk and reproduce a human-like hip torque during the stance phase of walking. With leg force and joint angle feedback inspired by the VPP template model, our controller provides hip and knee torque assistance during the stance phase. A pilot experiment was conducted with four healthy subjects. Joint kinematics, leg muscle electromyography (EMG), and metabolic cost were measured during walking with and without assistance. Results show that, for 0.6 m/s walking, our controller can reduce leg muscle activations, especially for the medial gastrocnemius (about 16.0%), while hip and knee joint kinematics remain similar to the condition without the controller. Besides, the controller also reduces 10% of the net metabolic cost during walking. This paper demonstrates walking assistance benefits of the VPP template model for the first time. The support of human walking is achieved by a force feedback of leg force applied to the control of hip and knee joints. It can help us to provide a framework for investigating walking assistance control in the future.

    This paper presents cross-disciplinary research between medical/psychological evidence on human abilities and informatics needs to update current models in computer science to support alternative methods for computation and communication. In [10] we have already proposed hypothesis introducing concept of human information model (HIM) as cooperative system. Here we continue on HIM design in detail. In our design, first we introduce Content/Form computing system which is new principle of present methods in evolutionary computing (genetic algorithms, genetic programming). Then we apply this system on HIM (type of artificial neural network) model as basic network self-developmental paradigm. Main inspiration of our natural/human design comes from well known concept of artificial neural networks, medical/psychological evidence and Sheldrake theory of "Nature as Alive" [22].

    2017-12-01

    Full Text Available The major goal of the paper was to develop a theoretical framework that conceptualizes the indirect impact on human resource management practice on knowledge sharing in the organization. In the current competitive environment, the ability to use knowledge assets and to continuously renovate it is required for organizational success. Therefore, the field of human resource management should dedicate great effort to understanding how to enhance the knowledge flows within the organization. Theoretical indications were provided about HRM practices that influence the quality and quantity of knowledge sharing within an organization. Further, a conceptual model of relations between HRM practices and factors influencing knowledge sharing within an organization was introduced. It is supposed that HRM practices have direct impacts on personality traits of employees, organizational culture, characteristics of managers, and instruments used for knowledge sharing. Subsequently, these factors have direct effects on the perceived intensity of knowledge sharing. The paper offers 12 testable propositions for the indirect relation between HRM practices and knowledge sharing in the organization. The suggested model could assist future research to examine the influence of HRM practices upon managing knowledge is a more complex way. Via a theoretical contribution to the debate on the influence on HRM practices upon managing knowledge, the study contributes to further research development in this field.

    Control of a multi-body system in both robots and humans may face the problem of destabilizing dynamic coupling effects arising between linked body segments. The state of the art solutions in robotics are full state feedback controllers. For human hip-ankle coordination, a more parsimonious and theoretically stable alternative to the robotics solution has been suggested in terms of the Eigenmovement (EM) control. Eigenmovements are kinematic synergies designed to describe the multi DoF system, and its control, with a set of independent, and hence coupling-free , scalar equations. This paper investigates whether the EM alternative shows "real-world robustness" against noisy and inaccurate sensors, mechanical non-linearities such as dead zones, and human-like feedback time delays when controlling hip-ankle movements of a balancing humanoid robot. The EM concept and the EM controller are introduced, the robot's dynamics are identified using a biomechanical approach, and robot tests are performed in a human posture control laboratory. The tests show that the EM controller provides stable control of the robot with proactive ("voluntary") movements and reactive balancing of stance during support surface tilts and translations. Although a preliminary robot-human comparison reveals similarities and differences, we conclude (i) the Eigenmovement concept is a valid candidate when different concepts of human sensorimotor control are considered, and (ii) that human-inspired robot experiments may help to decide in future the choice among the candidates and to improve the design of humanoid robots and robotic rehabilitation devices.

    Recent progress in human organoids has provided 3D tissue systems to model human development, diseases, as well as develop cell delivery systems for regenerative therapies. While direct differentiation of human embryoid bodies holds great promise for cardiac organoid production, intramyocardial cell organization during heart development provides biological foundation to fabricate human cardiac organoids with defined cell types. Inspired by the intramyocardial organization events in coronary vasculogenesis, where a diverse, yet defined, mixture of cardiac cell types self-organizes into functional myocardium in the absence of blood flow, we have developed a defined method to produce scaffold-free human cardiac organoids that structurally and functionally resembled the lumenized vascular network in the developing myocardium, supported hiPSC-CM development and possessed fundamental cardiac tissue-level functions. In particular, this development-driven strategy offers a robust, tunable system to examine the contributions of individual cell types, matrix materials and additional factors for developmental insight, biomimetic matrix composition to advance biomaterial design, tissue/organ-level drug screening, and cell therapy for heart repair.

    This paper proposes a novel bionic model of the human leg according to the theory of physiology. Based on this model, we present a biologically inspired 3-degree of freedom (DOF) lower limb exoskeleton for human gait rehabilitation, showing that the lower limb exoskeleton is fully compatible with the human knee joint. The exoskeleton has a hybrid serial-parallel kinematic structure consisting of a 1-DOF hip joint module and a 2-DOF knee joint module in the sagittal plane. A planar 2-DOF parallel mechanism is introduced in the design to fully accommodate the motion of the human knee joint, which features not only rotation but also relative sliding. Therefore, the design is consistent with the requirements of bionics. The forward and inverse kinematic analysis is studied and the workspace of the exoskeleton is analyzed. The structural parameters are optimized to obtain a larger workspace. The results using MATLAB-ADAMS co-simulation are shown in this paper to demonstrate the feasibility of our design. A prototype of the exoskeleton is also developed and an experiment performed to verify the kinematic analysis. Compared with existing lower limb exoskeletons, the designed mechanism has a large workspace, while allowing knee joint rotation and small amount of sliding.

  9. Developmentally inspired programming of adult human mesenchymal stromal cells toward stable chondrogenesis.

    It is generally accepted that adult human bone marrow-derived mesenchymal stromal cells (hMSCs) are default committed toward osteogenesis. Even when induced to chondrogenesis, hMSCs typically form hypertrophic cartilage that undergoes endochondral ossification. Because embryonic mesenchyme is obviously competent to generate phenotypically stable cartilage, it is questioned whether there is a correspondence between mesenchymal progenitor compartments during development and in adulthood. Here we tested whether forcing specific early events of articular cartilage development can program hMSC fate toward stable chondrogenesis. Inspired by recent findings that spatial restriction of bone morphogenetic protein (BMP) signaling guides embryonic progenitors toward articular cartilage formation, we hypothesized that selective inhibition of BMP drives the phenotypic stability of hMSC-derived chondrocytes. Two BMP type I receptor-biased kinase inhibitors were screened in a microfluidic platform for their time- and dose-dependent effect on hMSC chondrogenesis. The different receptor selectivity profile of tested compounds allowed demonstration that transient blockade of both ALK2 and ALK3 receptors, while permissive to hMSC cartilage formation, is necessary and sufficient to maintain a stable chondrocyte phenotype. Remarkably, even upon compound removal, hMSCs were no longer competent to undergo hypertrophy in vitro and endochondral ossification in vivo, indicating the onset of a constitutive change. Our findings demonstrate that adult hMSCs effectively share properties of embryonic mesenchyme in the formation of transient but also of stable cartilage. This opens potential pharmacological strategies to articular cartilage regeneration and more broadly indicates the relevance of developmentally inspired protocols to control the fate of adult progenitor cell systems.

    Full Text Available Tactile sensation is one type of valuable feedback in evaluating a product. Conventionally, sensory evaluation is used to get direct subjective responses from the consumers, in order to improve the product’s quality. However, this method is a time-consuming and costly process. Therefore, this paper proposes a novel tactile evaluation system that can give tactile feedback from a sensor’s output. The main concept of this system is hierarchically layering the tactile sensation, which is inspired by the flow of human perception. The tactile sensation is classified from low-order of tactile sensation (LTS to high-order of tactile sensation (HTS, and also to preference. Here, LTS will be correlated with physical measures. Furthermore, the physical measures that are used to correlate with LTS are selected based on four main aspects of haptic information (roughness, compliance, coldness, and slipperiness, which are perceived through human tactile sensors. By using statistical analysis, the correlation between each hierarchy was obtained, and the preference was derived in terms of physical measures. A verification test was conducted by using unknown samples to determine the reliability of the system. The results showed that the system developed was capable of estimating preference with an accuracy of approximately 80%.

  12. Posture Control—Human-Inspired Approaches for Humanoid Robot Benchmarking: Conceptualizing Tests, Protocols and Analyses

    2018-05-01

    Full Text Available Posture control is indispensable for both humans and humanoid robots, which becomes especially evident when performing sensorimotor tasks such as moving on compliant terrain or interacting with the environment. Posture control is therefore targeted in recent proposals of robot benchmarking in order to advance their development. This Methods article suggests corresponding robot tests of standing balance, drawing inspirations from the human sensorimotor system and presenting examples from robot experiments. To account for a considerable technical and algorithmic diversity among robots, we focus in our tests on basic posture control mechanisms, which provide humans with an impressive postural versatility and robustness. Specifically, we focus on the mechanically challenging balancing of the whole body above the feet in the sagittal plane around the ankle joints in concert with the upper body balancing around the hip joints. The suggested tests target three key issues of human balancing, which appear equally relevant for humanoid bipeds: (1 four basic physical disturbances (support surface (SS tilt and translation, field and contact forces may affect the balancing in any given degree of freedom (DoF. Targeting these disturbances allows us to abstract from the manifold of possible behavioral tasks. (2 Posture control interacts in a conflict-free way with the control of voluntary movements for undisturbed movement execution, both with “reactive” balancing of external disturbances and “proactive” balancing of self-produced disturbances from the voluntary movements. Our proposals therefore target both types of disturbances and their superposition. (3 Relevant for both versatility and robustness of the control, linkages between the posture control mechanisms across DoFs provide their functional cooperation and coordination at will and on functional demands. The suggested tests therefore include ankle-hip coordination. Suggested benchmarking

    Virtualization of wireless sensor networks (WSN) is widely considered as a foundational block of edge/fog computing, which is a key technology that can help realize next-generation Internet of things (IoT) networks. In such scenarios, multiple IoT devices and service modules will be virtually deployed and interconnected over the Internet. Moreover, application services are expected to be more sophisticated and complex, thereby increasing the number of modifications required for the construction of network topologies. Therefore, it is imperative to establish a method for constructing a virtualized WSN (VWSN) topology that achieves low latency on information transmission and high resilience against network failures, while keeping the topological construction cost low. In this study, we draw inspiration from inter-modular connectivity in human brain networks, which achieves high performance when dealing with large-scale networks composed of a large number of modules (i.e., regions) and nodes (i.e., neurons). We propose a method for assigning inter-modular links based on a connectivity model observed in the cerebral cortex of the brain, known as the exponential distance rule (EDR) model. We then choose endpoint nodes of these links by controlling inter-modular assortativity, which characterizes the topological connectivity of brain networks. We test our proposed methods using simulation experiments. The results show that the proposed method based on the EDR model can construct a VWSN topology with an optimal combination of communication efficiency, robustness, and construction cost. Regarding the selection of endpoint nodes for the inter-modular links, the results also show that high assortativity enhances the robustness and communication efficiency because of the existence of inter-modular links of two high-degree nodes.

    Cartilage defects are a persistent issue in orthopedic tissue engineering where acute and chronic tissue damage stemming from osteoarthritis, trauma, and sport injuries, present a common and serious clinical problem. Unlike bone, cartilage repair continues to be largely intractable due to the tissue's inherently poor regenerative capacity. Thus, the objective of this study is to design a novel tissue engineered nanostructured cartilage scaffold via biologically-inspired self-assembling rosette nanotubes (RNTs) and biocompatible non-woven poly (l-lactic acid) (PLLA) for enhanced human bone marrow mesenchymal stem cell (hMSC) chondrogenic differentiation. Specifically, RNTs are a new class of biomimetic supramolecular nanomaterial obtained through the self-assembly of low-molecular-weight modified guanine/cytosine DNA base hybrids (the G∧C motif) in an aqueous environment. In this study, we synthesized a novel twin G∧C-based RNT (TB-RGDSK) functionalized with cell-favorable arginine–glycine–aspartic acid–serine–lysine (RGDSK) integrin binding peptide and a twin G∧C based RNT with an aminobutane linker molecule (TBL). hMSC adhesion, proliferation and chondrogenic differentiation were evaluated in vitro in scaffold groups consisting of biocompatible PLLA with TBL, 1:9 TB-RGDSK:TBL, and TB-RGDSK, respectively. Our results show that RNTs can remarkably increase total glycosaminoglycan, collagen, and protein production when compared to PLLA controls without nanotubes. Furthermore, the TB-RGDSK with 100% well-organized RGDSK peptides achieved the highest chondrogenic differentiation of hMSCs. The current in vitro study illustrated that RNT nanotopography and surface chemistry played an important role in enhancing hMSC chondrogenic differentiation thus making them promising for cartilage regeneration.

  19. Retina-Inspired Filter.

    Doutsi, Effrosyni; Fillatre, Lionel; Antonini, Marc; Gaulmin, Julien

    2018-07-01

    This paper introduces a novel filter, which is inspired by the human retina. The human retina consists of three different layers: the Outer Plexiform Layer (OPL), the inner plexiform layer, and the ganglionic layer. Our inspiration is the linear transform which takes place in the OPL and has been mathematically described by the neuroscientific model "virtual retina." This model is the cornerstone to derive the non-separable spatio-temporal OPL retina-inspired filter, briefly renamed retina-inspired filter, studied in this paper. This filter is connected to the dynamic behavior of the retina, which enables the retina to increase the sharpness of the visual stimulus during filtering before its transmission to the brain. We establish that this retina-inspired transform forms a group of spatio-temporal Weighted Difference of Gaussian (WDoG) filters when it is applied to a still image visible for a given time. We analyze the spatial frequency bandwidth of the retina-inspired filter with respect to time. It is shown that the WDoG spectrum varies from a lowpass filter to a bandpass filter. Therefore, while time increases, the retina-inspired filter enables to extract different kinds of information from the input image. Finally, we discuss the benefits of using the retina-inspired filter in image processing applications such as edge detection and compression.

    Full Text Available The Human Resources Division of a company is a vital division. Most of the time, they perform their work manually, and therefore creating limitations to their capacity. The knowledge contained is very important for human resources development and subsequently for developing the company. In order to manage this knowledge well, the company shall require a knowledge management system. This knowledge management system would be a solution to be used for the company to manage all knowledge contained in that particular division. Phases in designing knowledge managements starts from analyzing knowledge sources of the company, knowledge identification and definition, and determining knowledge goals. Knowledge management systems contain many functions such as collecting, recording and managing the knowledge and sharing this to all related employees easily. The company may also use knowledge management systems to share and inform employees regarding updates of information, news and/or activity regarding the employees themselves. Information from knowledge management systems may also be used by employees to monitor their performance and thereby increasing it. Knowledge management systems may also help employees in their learning activities.Keywords: knowledge management, human resources, employee

    To determine the disposition and effects of caffeine after administration using a new dosage form (AeroShot) that delivers caffeine by inspiration of a fine powder into the oral cavity and compare it to an equivalent dose of an oral solution (energy drink) as the reference standard. Healthy human subjects (n = 17) inspired a 100 mg caffeine dose using the AeroShot device or consumed an energy drink on separate study days. Heart rate, blood pressure and subject assessments of effects were measured over an 8-h period. Plasma concentrations of caffeine and its major metabolites were determined by liquid chromatography-mass spectrometry. Pharmacokinetic, cardiovascular and perceived stimulant effects were compared between AeroShot and energy drink phases using a paired t test and standard bioequivalency analysis. Caffeine disposition was similar after caffeine administration by the AeroShot device and energy drink: peak plasma concentration 1790 and 1939 ng ml -1 , and area under the concentration-time curve (AUC) 15 579 and 17 569 ng ml -1 × h, respectively, but they were not bioequivalent: AeroShot AUC of 80.3% (confidence interval 71.2-104.7%) and peak plasma concentration of 86.3% (confidence interval 62.8-102.8%) compared to the energy drink. Female subjects did have a significantly larger AUC compared to males after consumption of the energy drink. The heart rate and blood pressure were not significantly affected by the 100 mg caffeine dose, and there were no consistently perceived stimulant effects by the subjects using visual analogue scales. Inspiration of caffeine as a fine powder using the AeroShot device produces a similar caffeine profile and effects compared to administration of an oral solution (energy drink). © 2017 The British Pharmacological Society.

  6. Origins and early development of human body knowledge.

    Slaughter, Virginia; Heron, Michelle

    2004-01-01

    As a knowable object, the human body is highly complex. Evidence from several converging lines of research, including psychological studies, neuroimaging and clinical neuropsychology, indicates that human body knowledge is widely distributed in the adult brain, and is instantiated in at least three partially independent levels of representation. Sensorimotor body knowledge is responsible for on-line control and movement of one's own body and may also contribute to the perception of others' moving bodies; visuo-spatial body knowledge specifies detailed structural descriptions of the spatial attributes of the human body; and lexical-semantic body knowledge contains language-based knowledge about the human body. In the first chapter of this Monograph, we outline the evidence for these three hypothesized levels of human body knowledge, then review relevant literature on infants' and young children's human body knowledge in terms of the three-level framework. In Chapters II and III, we report two complimentary series of studies that specifically investigate the emergence of visuo-spatial body knowledge in infancy. Our technique is to compare infants'responses to typical and scrambled human bodies, in order to evaluate when and how infants acquire knowledge about the canonical spatial layout of the human body. Data from a series of visual habituation studies indicate that infants first discriminate scrambled from typical human body picture sat 15 to 18 months of age. Data from object examination studies similarly indicate that infants are sensitive to violations of three-dimensional human body stimuli starting at 15-18 months of age. The overall pattern of data supports several conclusions about the early development of human body knowledge: (a) detailed visuo-spatial knowledge about the human body is first evident in the second year of life, (b) visuo-spatial knowledge of human faces and human bodies are at least partially independent in infancy and (c) infants' initial

    CERN has been involved in the dissemination of scientific results since its early days and has continuously updated the distribution channels. Currently, Inspire hosts catalogues of articles, authors, institutions, conferences, jobs, experiments, journals and more. Successful orientation among this amount of data requires comprehensive linking between the content. Inspire has lacked a system for linking experiments and articles together based on which accelerator they were conducted at. The purpose of this project has been to create such a system. Records for 156 accelerators were created and all 2913 experiments on Inspire were given corresponding MARC tags. Records of 18404 accelerator physics related bibliographic entries were also tagged with corresponding accelerator tags. Finally, as a part of the endeavour to broaden CERN's presence on Wikipedia, existing Wikipedia articles of accelerators were updated with short descriptions and links to Inspire. In total, 86 Wikipedia articles were updated. This repo...

    Full Text Available The widespread enthusiasm for a knowledge-based approach to understanding the nature of a business and the possible basis for sustained competitive advantage have renewed interest in human capital evaluation or measurement. While many attempts have been made to develop methods for measuring intellectual capital, none have been widely adopted in the business world. In the knowledge-based organizations, and generally, in the information society, human capital is recognized as the fundamental factor of overall progress, and experts agree that long-term investment in human capital has strong drive-propagation effects at the individual, organizational, national and global level. In this paper, we consider that a knowledge-based approach can offer new possibilities and answers to illustrate the importance of evaluation the human capital and knowledge assets by consistently generating added value in the business world.

    Marczak, Elzbieta

    2017-10-01

    Sea-going vessels have for centuries fascinated people, not only those who happen to work at sea, but first and foremost, those who have never set foot aboard a ship. The environment in which ships operate is reminiscent of freedom and countless adventures, but also of hard and interesting maritime working life. The famous words of Pompey: “Navigare necesseest, vivere non estnecesse” (sailing is necessary, living - is not necessary), which he pronounced on a stormy sea voyage, arouse curiosity and excitement, inviting one to test the truth of this saying personally. It is often the case, however, that sea-faring remains within the realm of dreams, while the fascination with ships demonstrates itself through a transposition of naval features onto land constructions. In such cases, ship-inspired motifs bring alive dreams and yearnings as well as reflect tastes. Tourism is one of the indicators of people’s standard of living and a measure of a society’s civilisation. Maritime tourism has been developing rapidly in recent decades. A sea cruise offers an insight into life at sea. Still, most people derive their knowledge of passenger vessels and their furnishings from the mass media. Passenger vessels, also known as “floating cities,” are described as majestic and grand, while their on-board facilities as luxurious, comfortable, exclusive and inaccessible to common people on land. Freight vessels, on the other hand, are described as enormous objects which dwarf the human being into insignificance. This article presents the results of research intended to answer the following questions: what makes ships a source of inspiration for land architecture? To what extent and by what means do architects draw on ships in their design work? In what places can we find structures inspired by ships? What ships inspire architects? This article presents examples of buildings, whose design was inspired by the architecture and structural details of sea vessels. An analysis of

    2009-03-01

    Recent years have seen convergence in research on brain mechanisms and neurocomputational approaches, culminating in the creation of a new generation of robots whose artificial "brains" respect neuroscience principles and whose "cognitive" systems venture into higher cognitive domains such as planning and action sequencing, complex object and concept processing, and language. The present article gives an overview of selected projects in this general multidisciplinary field. The work reviewed centres on research funded by the EU in the context of the New and Emergent Science and Technology, NEST, funding scheme highlighting the topic "What it means to be human". Examples of such projects include learning by imitation (Edici project), examining the origin of human rule-based reasoning (Far), studying the neural origins of language (Neurocom), exploring the evolutionary origins of the human mind (Pkb140404), researching into verbal and non-verbal communication (Refcom), using and interpreting signs (Sedsu), characterising human language by structural complexity (Chlasc), and representing abstract concepts (Abstract). Each of the communication-centred research projects revealed individual insights; however, there had been little overall analysis of results and hypotheses. In the Specific Support Action Nestcom, we proposed to analyse some NEST projects focusing on the central question "What it means to communicate" and to review, understand and integrate the results of previous communication-related research, in order to develop and communicate multimodal experimental hypotheses for investigation by future projects. The present special issue includes a range of papers on the interplay between neuroinformatics, brain science and robotics in the general area of higher cognitive functions and multimodal communication. These papers extend talks given at the NESTCOM workshops, at ICANN (http://www.his.sunderland.ac.uk/nestcom/workshop/icann.html) in Porto and at the first

    2006-04-01

    The success of mammal cloning in 1997 has brought the issue of human cloning into public discussion. Human cloning has several aspects and potential applications for use in both reproductive and non-reproductive matters. The aim of this study was to evaluate the knowledge and attitudes toward human cloning in Israel. Data from 120 respondents (68 health professionals and 52 non-health professionals), all Jewish, Hebrew speaking with at least 15 years of education each, were collected using two questionnaires that dealt with knowledge and attitudes toward human cloning. Results showed that although health professionals had significantly more knowledge that non-health professionals, all respondents had poor knowledge about cloning. No difference in attitudes was found between the groups. Most respondents opposed human cloning, but more positive attitudes toward non-reproductive cloning were found. The results are discussed in the context of the deficit model. The findings indicate a need to provide information about human cloning to allow people to form their attitudes based on factual knowledge.

    Coastal monitoring has become reliant upon automated sensors for data acquisition. Such a technical commitment comes with a cost; particularly, the generation of large, high-dimensional data streams ('Big Data') that personnel must search through to identify data structures. Nature-inspired computation, inclusive of artificial neural networks (ANNs), affords the unearthing of complex, recurring patterns within sizable data volumes. In 2009, select meteorological and hydrological data were acquired via autonomous instruments in Sarasota Bay, Florida (USA). ANNs estimated continuous chlorophyll (CHL) a concentrations from abiotic predictors, with correlations between measured:modeled concentrations >0.90 and model efficiencies ranging from 0.80 to 0.90. Salinity and water temperature were the principal influences for modeled CHL within the Bay; concentrations steadily increased at temperatures >28° C and were greatest at salinities 6.1 μg CHL L-1 maximized at a salinity of ca. 36.3 and a temperature of ca. 29.5 °C. A 10th-order Chebyshev bivariate polynomial equation was fit (adj. r2 = 0.99, p turbidity, temperature, and salinity (and to lesser degrees, wind speed, wind/current direction, irradiance, and urea-nitrogen) were key variables for quantitative rules in tree formalisms. Taken together, computations enabled knowledge provision for and quantifiable representations of the non-linear relationships between environmental variables and CHL a.

    Topical delivery methods like nasal sprays are an important therapeutic component for sinusitis (inflammation and clogging of the paranasal sinuses). The sinuses are air-filled sacs, identified as: maxillaries (under the eyes and deep to cheeks bilaterally; largest in volume), frontals (above and medial to the eyes, behind forehead area), ethmoids (between the eyes, inferior to the frontal sinuses), and sphenoids (superior and posterior to ethmoids). We develop anatomic CT-based 3D reconstructions of the human nasal cavity for multiple subjects. Through CFD simulations on Fluent for measured breathing rates, we track inspiratory airflow in all the models and the corresponding sprayed drug transport (for a commercially available sprayer, with experimentally tested particle size distributions). The protocol is implemented for a wide array of spray release points. We make the striking observation that the same release points in each subject provide better particle deposition in all the sinuses, despite the sinuses being located at different portions of the nasal cavity. This leads to the conjecture that the complicated anatomy-based flow physics artifacts in the nasal canal generate certain ``magical'' streamlines, providing passage for improved drug transport to all sinus targets.

    In essence, the virtual physiological human (VPH) is a multiscale representation of human physiology spanning from the molecular level via cellular processes and multicellular organization of tissues to complex organ function. The different scales of the VPH deal with different entities, relationships and processes, and in consequence the models used to describe and simulate biological functions vary significantly. Here, we describe methods and strategies to generate knowledge environments representing molecular entities that can be used for modelling the molecular scale of the VPH. Our strategy to generate knowledge environments representing molecular entities is based on the combination of information extraction from scientific text and the integration of information from biomolecular databases. We introduce @neuLink, a first prototype of an automatically generated, disease-specific knowledge environment combining biomolecular, chemical, genetic and medical information. Finally, we provide a perspective for the future implementation and use of knowledge environments representing molecular entities for the VPH.

    In Knowledge Machines, Eric Meyer and Ralph Schroeder argue that digital technologies have fundamentally changed research practices in the sciences, social sciences, and humanities. Meyer and Schroeder show that digital tools and data, used collectively and in distributed mode -- which they term e-research -- have transformed not just the consumption of knowledge but also the production of knowledge. Digital technologies for research are reshaping how knowledge advances in disciplines that range from physics to literary analysis. Meyer and Schroeder map the rise of digital research and offer case studies from many fields, including biomedicine, social science uses of the Web, astronomy, and large-scale textual analysis in the humanities. They consider such topics as the challenges of sharing research data and of big data approaches, disciplinary differences and new forms of interdisciplinary collaboration, the shifting boundaries between researchers and their publics, and the ways that digital tools promote o...

    Infection by human papillomavirus (HPV) is one of common sexually transmitted diseases leading to cervical cancer. Evaluation of parental knowledge and attitudes toward HPV were aims of present study to provide an appropriate method to decrease burden of this infection on society. During this study, 358 parents were assessed for knowledge about HPV and its related disorders. Some 76% of parents had no information about HPV infection and among the informed parents 36% had obtained their information via internet and others from studying medical resources. The average score of mothers information about HPV infection was higher than that of fathers, and also educational level and age had significant impact on knowledge of parents about HPV. Parent knowledge about the hazards of HPV was higher than their knowledge about modes of transmission. Lack of awareness about HPV infection was high in this study, underlining the urgency of education among all adult people in our society.

  12. Dynamic response and transfer function of social systems: A neuro-inspired model of collective human activity patterns.

    Lymperopoulos, Ilias N

    2017-10-01

    The interaction of social networks with the external environment gives rise to non-stationary activity patterns reflecting the temporal structure and strength of exogenous influences that drive social dynamical processes far from an equilibrium state. Following a neuro-inspired approach, based on the dynamics of a passive neuronal membrane, and the firing rate dynamics of single neurons and neuronal populations, we build a state-of-the-art model of the collective social response to exogenous interventions. In this regard, we analyze online activity patterns with a view to determining the transfer function of social systems, that is, the dynamic relationship between external influences and the resulting activity. To this end, first we estimate the impulse response (Green's function) of collective activity, and then we show that the convolution of the impulse response with a time-varying external influence field accurately reproduces empirical activity patterns. To capture the dynamics of collective activity when the generating process is in a state of statistical equilibrium, we incorporate into the model a noisy input convolved with the impulse response function, thus precisely reproducing the fluctuations of stationary collective activity around a resting value. The outstanding goodness-of-fit of the model results to empirical observations, indicates that the model explains human activity patterns generated by time-dependent external influences in various socio-economic contexts. The proposed model can be used for inferring the temporal structure and strength of external influences, as well as the inertia of collective social activity. Furthermore, it can potentially predict social activity patterns. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Human sensory systems allow individuals to see, hear, touch, and interact with the surrounding physical environment. Understanding human perception and its limit enables us to better exploit the psychophysics of human perceptual systems to design more efficient, adaptive algorithms and develop perceptually-inspired computational models. In this talk, I will survey some of recent efforts on perceptually-inspired computing with applications to crowd simulation and multimodal interaction. In particular, I will present data-driven personality modeling based on the results of user studies, example-guided physics-based sound synthesis using auditory perception, as well as perceptually-inspired simplification for multimodal interaction. These perceptually guided principles can be used to accelerating multi-modal interaction and visual computing, thereby creating more natural human-computer interaction and providing more immersive experiences. I will also present their use in interactive applications for entertainment, such as video games, computer animation, and shared social experience. I will conclude by discussing possible future research directions.

    1986-01-01

    A radiotracer technique has been used to assess the effects of a 700-ml collapsible holding chamber (InspirEase, Key Pharmaceuticals Inc.) on the deposition of metered-dose aerosols in ten patients with obstructive airways disease (mean forced expiratory volume in one second [FEV1], 64.5 percent of predicted). Patterns of deposition obtained by patients' usual techniques with the metered-dose inhaler (MDI) were compared with those by correct MDI technique (actuation coordinated with slow deep inhalation and followed by ten seconds of breath-holding) and with those by InspirEase. Deposition of aerosol was assessed by placing Teflon particles labelled with 99mTc inside placebo canisters, and inhaling maneuvers were monitored by respiratory inductive plethysmography (Respitrace). Nine of the ten patients had imperfect technique with the MDI, the most prevalent errors being rapid inhalation and failure to hold their breath adequately. With patients' usual MDI techniques, 6.5 +/- 1.2 percent (mean +/- SE) of the dose reached the lungs. This was increased to 11.2 +/- 1.3 percent (p less than 0.02) with correct technique and increased further to 14.8 +/- 1.4 percent (p less than 0.05) with InspirEase. Oropharyngeal deposition exceeded 80 percent of the dose for the MDI alone but was only 9.5 +/- 0.9 percent with InspirEase (p less than 0.01); 59.2 +/- 2.1 percent of the dose was retained within InspirEase itself. It is concluded that InspirEase gives whole lung deposition of metered-dose aerosols greater than that from a correctly used MDI, while oropharyngeal deposition is reduced approximately nine times

    Background Human Papilloma Virus (HPV) vaccine has undergone successful trials and has recently been approved for use for the primary prevention of cervical cancer. The aim of this study was to determine knowledge and attitudes towards HPV vaccination. Methods Semi-structured interview and questionnaire delivered in a street survey. Standardised HPV-related statements used to measure HPV knowledge and attitudes to vaccination. The setting was three different areas of Birmingham, to target a mix of social class and ethnicity. The sample population was composed of 16–54 year olds. Results A total of 420 participants were recruited. Poor knowledge of HPV and its links with cervical cancer were observed. 81% had a knowledge score of zero. Knowledge about HPV was associated with different ethnic group and socio-economic group. The majority (88%) of participants were in favour of vaccination, with 83.6% indicating that they would allow a child under their care to be vaccinated. Conclusion Initial responses to the proposed HPV vaccination within the UK public are favourable. However, knowledge levels are poor and media and health professional promotion are required to raise awareness. PMID:18947430

    We propose an iterative and human-centred knowledge discovery methodology based on formal concept analysis. The proposed approach recognizes the important role of the domain expert in mining real-world enterprise applications and makes use of specific domain knowledge, including human intelligence and domain-specific constraints. Our approach was empirically validated at the Amsterdam-Amstelland police to identify suspects and victims of human trafficking in 266,157 suspicious activity reports. Based on guidelines of the Attorney Generals of the Netherlands, we first defined multiple early warning indicators that were used to index the police reports. Using concept lattices, we revealed numerous unknown human trafficking and loverboy suspects. In-depth investigation by the police resulted in a confirmation of their involvement in illegal activities resulting in actual arrestments been made. Our human-centred approach was embedded into operational policing practice and is now successfully used on a daily basis to cope with the vastly growing amount of unstructured information.

    Full Text Available Nowadays, great amount of data is being created by several sources from academic, scientific, business and industrial activities. Such data intrinsically contains meaningful information allowing for developing techniques, and have scientific validity to explore the information thereof. In this connection, the aim of artificial intelligence (AI is getting new knowledge to make decisions properly. AI has taken an important place in scientific and technology development communities, and recently develops computer-based processing devices for modern machines. Under the premise, the premise that the feedback provided by human reasoning -which is holistic, flexible and parallel- may enhance the data analysis, the need for the integration of natural and artificial intelligence has emerged. Such an integration makes the process of knowledge discovery more effective, providing the ability to easily find hidden trends and patterns belonging to the database predictive model. As well, allowing for new observations and considerations from beforehand known data by using both data analysis methods and knowledge and skills from human reasoning. In this work, we review main basics and recent works on artificial and natural intelligence integration in order to introduce users and researchers on this emergent field. As well, key aspects to conceptually compare them are provided.

    Full Text Available In the global crisis context crossed by organizations and countries in the past six years we assist also at conflicting measures in which regards knowledge, innovation and human capital; for example, countries such as England and France have reduced their costs for education, while Germany and other countries (Australia, Austria, Canada and Norway maintained the same allocations for education. What will be the effects of such measures on human capital in the near future? What are the best human resources policies in companies in the crisis context? Given that the subject of the research is "knowledge and human capital", in this paper we refer to the induced effects of the crisis on human capital and innovation. We will also identify the key steps that can be taken during crisis, and not only, to stimulate human capital.

    Proteins and their interactions are considered to play a significant role in many cellular processes. The identification of Protein-Protein interactions (PPIs) in human is an open research area. Many Databases, which contain information about experimentally and computationally detected human PPIs as well as their corresponding annotation data, have been developed. However, these databases contain many false positive interactions, are partial and only a few of them incorporate data from various sources. To overcome these limitations, we have developed HINT-KB (http://150.140.142.24:84/Default.aspx) which is a knowledge base that integrates data from various sources, provides a user-friendly interface for their retrieval, estimates a set of features of interest and computes a confidence score for every candidate protein interaction using a modern computational hybrid methodology. © 2012 IFIP International Federation for Information Processing.

    2016-04-01

    Neuroscience research has examined separately how we detect human agents on the basis of their face and body (person perception) and how we reason about their thoughts, traits or intentions (person knowledge). Neuroanatomically distinct networks have been associated with person perception and person knowledge, but it remains unknown how multiple features of a person (e.g. thin and kind) are linked to form a holistic identity representation. In this fMRI experiment, we investigated the hypothesis that when encountering another person specialised person perception circuits would be functionally coupled with circuits involved in person knowledge. In a factorial design, we paired bodies or names with trait-based or neutral statements, and independent localiser scans identified body-selective and mentalising networks. When observing a body paired with a trait-implying statement, functional connectivity analyses demonstrated that body-selective patches in bilateral fusiform gyri were functionally coupled with nodes of the mentalising network. We demonstrate that when forming a representation of a person circuits for representing another person's physical appearance are linked to circuits that are engaged when reasoning about trait-based character. These data support the view that a 'who' system for social cognition involves communication between perceptual and inferential mechanisms when forming a representation of another's identity. © The Author (2016).

    Human teeth are anisotropic composites. Dentin as the core material of the tooth consists of nanometer-sized calcium phosphate crystallites embedded in collagen fiber networks. It shows its anisotropy on the micrometer scale by its well-oriented microtubules. The detailed three-dimensional nanostructure of the hard tissues namely dentin and enamel, however, is not understood, although numerous studies on the anisotropic mechanical properties have been performed and evaluated to explain the tooth function including the enamel-dentin junction acting as effective crack barrier. Small angle X-ray scattering (SAXS) with a spatial resolution in the 10 μm range allows determining the size and orientation of the constituents on the nanometer scale with reasonable precision. So far, only some dental materials, i.e. the fiber reinforced posts exhibit anisotropic properties related to the micrometer-size glass fibers. Dental fillings, composed of nanostructures oriented similar to the natural hard tissues of teeth, however, do not exist at all. The current X-ray-based investigations of extracted human teeth provide evidence for oriented micro- and nanostructures in dentin and enamel. These fundamental quantitative findings result in profound knowledge to develop biologically inspired dental fillings with superior resistance to thermal and mechanical shocks.

    A long-standing goal of artificial intelligence is an algorithm that learns, tabula rasa, superhuman proficiency in challenging domains. Recently, AlphaGo became the first program to defeat a world champion in the game of Go. The tree search in AlphaGo evaluated positions and selected moves using deep neural networks. These neural networks were trained by supervised learning from human expert moves, and by reinforcement learning from self-play. Here we introduce an algorithm based solely on reinforcement learning, without human data, guidance or domain knowledge beyond game rules. AlphaGo becomes its own teacher: a neural network is trained to predict AlphaGo’s own move selections and also the winner of AlphaGo’s games. This neural network improves the strength of the tree search, resulting in higher quality move selection and stronger self-play in the next iteration. Starting tabula rasa, our new program AlphaGo Zero achieved superhuman performance, winning 100-0 against the previously published, champion-defeating AlphaGo.

    2017-12-01

    More than 35 years since the HIV/AIDS pandemic began, HIV continues to cause almost two million new infections each year, and the "end of AIDS" by 2030 remains elusive. 1 Violations of human rights continue to fuel high rates of new infections among key populations and a generalized epidemic in much of sub-Saharan Africa. Meanwhile, as political shifts worldwide threaten not only HIV funding but also progress toward the globalization of human rights, civil society mobilization and advocacy founded firmly on human rights principles have a more vital role to play than ever. Encouragingly, there are numerous examples of successful integration of human rights-based approaches into HIV prevention and treatment initiatives, and evidence increasingly demonstrates that norms enshrining the respect, protection, and fulfillment of human rights can translate into improved public health. 2 This essay will succinctly trace the historic emergence of human rights as an issue at the heart of the HIV/AIDS response; it will then provide examples of progress and setbacks in recent years and consider the potential for rights promotion to address the structural drivers of HIV. Finally, it will consider how the primacy of human rights in HIV/AIDS has affected other fields of global health and will highlight the continuing imperative to work with civil society to protect and promote human rights to reduce the burden of HIV/AIDS.

    Since the 2008 introduction of the human papillomavirus (HPV) vaccination programme for adolescent girls in the UK, parents and other groups have expressed fears that immunisation condones sexual activity, promotes promiscuity and encourages risky sexual behaviour. This study aimed to explore whether HPV vaccination programmes have increased knowledge surrounding HPV and associated disease and whether uptake has influenced sexual behaviour. MEDLINE, Embase, Cochrane Library and PsycINFO electronic databases were interrogated. Studies of behaviour, attitudes and knowledge associated with HPV vaccination (or vaccination intent) in subjects of any age and gender in programmes reflective of UK practice were included in the review (n = 58). The evidence regarding the association of HPV vaccination with high-risk sexual behaviour was varied, primarily due to the heterogeneous nature of the included studies. Young females typically exhibited better knowledge than males, and vaccinated respondents (or those with vaccination intent) had higher levels of knowledge than the unvaccinated. However, knowledge surrounding HPV and genital warts was generally poor. This review highlights the need to provide effective education regarding the HPV vaccine and HPV-associated disease to adolescents of vaccination age, nurses, teachers, parents and guardians to ultimately allow informed decisions to be made regarding receipt of the HPV vaccine. © The Author(s) 2015.

    Breathing, laughing, sneezing and coughing are all important human behaviors that are generated in the torso. Yet, when these behaviors are animated, the movement of the human torso is often simplified and stylized. Recent work aiming to depict the movement of the torso has focused on pure data-driven approaches such as a skin capture of an actor using a motion capture system. Although this generates impressive results to recreate the captured motion, it does not provide control to an animato...

    Converging reports indicate that face images are processed through specialized neural networks in the brain -i.e. face patches in monkeys and the fusiform face area (FFA) in humans. These studies were designed to find out how faces are processed in visual system compared to other objects. Yet, the underlying mechanism of face processing is not completely revealed. Here, we show that a hierarchical computational model, inspired by electrophysiological evidence on face processing in primates, is able to generate representational properties similar to those observed in monkey face patches (posterior, middle and anterior patches). Since the most important goal of sensory neuroscience is linking the neural responses with behavioral outputs, we test whether the proposed model, which is designed to account for neural responses in monkey face patches, is also able to predict well-documented behavioral face phenomena observed in humans. We show that the proposed model satisfies several cognitive face effects such as: composite face effect and the idea of canonical face views. Our model provides insights about the underlying computations that transfer visual information from posterior to anterior face patches.

    Mohr, Johannes; Park, Jong-Han; Obermayer, Klaus

    2014-12-01

    Humans are highly efficient at visual search tasks by focusing selective attention on a small but relevant region of a visual scene. Recent results from biological vision suggest that surfaces of distinct physical objects form the basic units of this attentional process. The aim of this paper is to demonstrate how such surface-based attention mechanisms can speed up a computer vision system for visual search. The system uses fast perceptual grouping of depth cues to represent the visual world at the level of surfaces. This representation is stored in short-term memory and updated over time. A top-down guided attention mechanism sequentially selects one of the surfaces for detailed inspection by a recognition module. We show that the proposed attention framework requires little computational overhead (about 11 ms), but enables the system to operate in real-time and leads to a substantial increase in search efficiency.

Furthermore, the differences between the Malay, Chinese and Indian ethnicities are researched for the presence of humanness and the willingness to share knowledge. Two hundred and fourteen respondents from privately owned companies participated in this research showing that there is a strong relationship between humanness and knowledge sharing. However, the differences between the three ethnicities are small, which is a surprising finding. It can be concluded that people-oriented managers (one of the ways to express humanness are more willing to share knowledge, and differences between ethnicities have no influence in this matter. From these results, it can be recommended to managers and organizations in Malaysia that they pay more attention and be aware of their management style.Stressing the humanness aspects more as they are described could improve the knowledge transfer within companies.

  9. Linking departmental priorities to knowledge management: the experiences of Santa Cruz County's Human Services Department.

    Science.gov (United States)

    Lindberg, Arley

    2012-01-01

    Federal welfare reform, local service collaborations, and the evolution of statewide information systems inspired agency interest in evidence-informed practice and knowledge sharing systems. Four agency leaders, including the Director, Deputy Director, Director of Planning and Evaluation, and Staff Development Program Manager championed the development of a learning organization based on knowledge management throughout the agency. Internal department restructuring helped to strengthen the Planning and Evaluation, Staff Development, and Personnel units, which have become central to supporting knowledge sharing activities. The Four Pillars of Knowledge framework was designed to capture agency directions in relationship to future knowledge management goals. Featuring People, Practice, Technology and Budget, the framework links the agency's services, mission and goals to the process of becoming a learning organization. Built through an iterative process, the framework was created by observing existing activities in each department rather than being designed from the top down. Knowledge management can help the department to fulfill its mission despite reduced resources. Copyright © Taylor & Francis Group, LLC

    The Human Genome Project was completed a decade ago, leaving a legacy of process, tools, and infrastructure now being turned to the study of the microbes that reside in and on the human body as determinants of health and disease, and has been branded "The Human Microbiome Project." Of the various niches under investigation, the human gut houses the most complex and abundant microbial community and is an arena for important host-microbial interactions that have both local and systemic impact. Initial studies of the human microbiome have been largely descriptive, a testing ground for innovative molecular techniques and new hypotheses. Methods for studying the microbiome have quickly evolved from low-resolution surveys of microbial community structure to high-definition description of composition, function, and ecology. Next-generation sequencing technologies combined with advanced bioinformatics place us at the doorstep of revolutionary insight into the composition, capability, and activity of the human intestinal microbiome. Renewed efforts to cultivate previously "uncultivable" microbes will be important to the overall understanding of gut ecology. There remain numerous methodological challenges to the effective study and understanding of the gut microbiome, largely relating to study design, sample collection, and the number of predictor variables. Strategic collaboration of clinicians, microbiologists, molecular biologists, computational scientists, and bioinformaticians is the ideal paradigm for success in this field. Meaningful interpretation of the gut microbiome requires that host genetic and environmental influences be controlled or accounted for. Understanding the gut microbiome in healthy humans is a foundation for discovering its influence in various important gastrointestinal and nutritional diseases (eg, inflammatory bowel disease, diabetes, and obesity), and for rational translation to human health gains.

  19. Using Specification and Description Language (SDL) for capturing and reusing human experts' knowledge

    International Nuclear Information System (INIS)

    Far, B.H.; Koono, Zenya

    1994-01-01

    Conventional knowledge engineering techniques for acquiring experts' knowledge can not produce quality knowledge due to improper knowledge documentation and informal knowledge acquisition method. We propose a new method for knowledge documentation and acquisition using Specification and Description Language (SDL). SDL is used to describe both the target system and the reasoning process. The main idea is to follow deterministic problem solving behavior of human experts and document it. Then knowledge can be extracted by comparing documents of the successive steps. This knowledge is recorded and reused in similar or novel cases. We present an implementation of this method in a tool for software design. The implemented system consists of a SDL CASE tool and an expert system for applying the design knowledge. This system serves as an experimental platform for the study of human design by simulating the design at the lowest level. However, we have found that by acquiring enough domain knowledge, this system can simulate general problem solving of human experts. (author)

    CERN Bulletin

    2010-01-01

    Particle physicists thrive on information. They first create information by performing experiments or elaborating theoretical conjectures and then they share it through publications and various web tools. The INSPIRE service, just released, will bring state of the art information retrieval to the fingertips of researchers.   Keeping track of the information shared within the particle physics community has long been the task of libraries at the larger labs, such as CERN, DESY, Fermilab and SLAC, as well as the focus of indispensible services like arXiv and those of the Particle Data Group. In 2007, many providers of information in the field came together for a summit at SLAC to see how physics information resources could be enhanced, and the INSPIRE project emerged from that meeting. The vision behind INSPIRE was built by a survey launched by the four labs to evaluate the real needs of the community. INSPIRE responds to these directives from the community by combining the most successful aspe...

    2006-01-01

    Evolution allowed nature to introduce highly effective biological mechanisms that are incredible inspiration for innovation. Humans have always made efforts to imitate nature's inventions and we are increasingly making advances that it becomes significantly easier to imitate, copy, and adapt biological methods, processes and systems. This brought us to the ability to create technology that is far beyond the simple mimicking of nature. Having better tools to understand and to implement nature's principles we are now equipped like never before to be inspired by nature and to employ our tools in far superior ways. Effectively, by bio-inspiration we can have a better view and value of nature capability while studying its models to learn what can be extracted, copied or adapted. Using electroactive polymers (EAP) as artificial muscles is adding an important element to the development of biologically inspired technologies.

    Full Text Available I have to admit that writing an editorial for this issue was a struggle. Trying to sit down and write when the sun was shining outside and most of my colleagues were on vacation was, to say the least, difficult. Add to that research projects and conferences…let’s just say that I found myself less than inspired. A pitiful plea for ideas to a colleague resulted in the reintroduction to a few recent evidence based papers and resources which inspired further searching and reading. Though I generally find myself surrounded (more like buried in research papers and EBLIP literature, somehow I had missed the great strides that have been made of late in the world of evidence based library and information practice. I realize now that I am inspired by the researchers, authors and innovators who are putting EBLIP on the proverbial map. My biggest beef with library literature in general has been the plethora of articles highlighting what we should be doing. Take a close look at the evidence based practitioners in the information professions: these are some of the people who are actively practicing what has been preached for the past few years. Take, for example, the about‐to‐be released Libraries using Evidence Toolkit by Northern Sydney Central Coast Health and The University of Newcastle, Australia (see their announcement in this issue. An impressive advisory group is responsible for maintaining the currency and relevancy of the site as well as promoting the site and acting as a steering committee for related projects. This group is certainly doing more than “talking the talk”: they took their experience at the 3rd International Evidence Based Librarianship Conference and did something with the information they obtained by implementing solutions that worked in their environment. The result? The creation of a collection of tools for all of us to use. This toolkit is just what EBLIP needs: a portal to resources aimed at supporting the information

  6. Drawing on student knowledge in human anatomy and physiology

    Slominski, Tara Nicole

    Prior to instruction, students may have developed alternative conceptions about the mechanics behind human physiology. To help students re-shape these ideas into correct reasoning, the faulty characteristics reinforcing the alternative conceptions need to made explicit. This study used student-generated drawings to expose alternative conceptions Human Anatomy and Physiology students had prior to instruction on neuron physiology. Specifically, we investigated how students thought about neuron communication across a synapse (n=355) and how neuron activity can be modified (n=311). When asked to depict basic communication between two neurons, at least 80% of students demonstrated incorrect ideas about synaptic transmission. When targeting spatial and temporal summation, only eleven students (3.5%) were able to accurately depict at least one form of summation. In response to both drawing questions, student drawings revealed multiple alternative conceptions that resulted in a deeper analysis and characterization of the wide variation of student ideas.

    The fields of neuroscience and artificial intelligence (AI) have a long and intertwined history. In more recent times, however, communication and collaboration between the two fields has become less commonplace. In this article, we argue that better understanding biological brains could play a vital role in building intelligent machines. We survey historical interactions between the AI and neuroscience fields and emphasize current advances in AI that have been inspired by the study of neural computation in humans and other animals. We conclude by highlighting shared themes that may be key for advancing future research in both fields. Copyright © 2017. Published by Elsevier Inc.

  14. Integrated approach to knowledge acquisition and safety management of complex plants with emphasis on human factors

    International Nuclear Information System (INIS)

    Kosmowski, K.T.

    1998-01-01

    In this paper an integrated approach to the knowledge acquisition and safety management of complex industrial plants is proposed and outlined. The plant is considered within a man-technology-environment (MTE) system. The knowledge acquisition is aimed at the consequent reliability evaluation of human factor and probabilistic modeling of the plant. Properly structured initial knowledge is updated in life-time of the plant. The data and knowledge concerning the topology of safety related systems and their functions are created in a graphical CAD system and are object oriented. Safety oriented monitoring of the plant includes abnormal situations due to external and internal disturbances, failures of hard/software components and failures of human factor. The operation and safety related evidence is accumulated in special data bases. Data/knowledge bases are designed in such a way to support effectively the reliability and safety management of the plant. (author)

    Chris W. Callaghan

    2016-04-01

    Research purpose: This article relates certain changes in HRM over time to the argument that there has been a shift from an industrial paradigm (on which many human resource [HR] systems, practices and theoretical frameworks are still based to a knowledge paradigm (of knowledge work, in which employee knowledge and skills offer compound advantages that are not substitutable which explains a great deal of the variance in changes of the field over time. Motivation for the study: It is argued that in order for the field to move forward, it may needto bring to the surface certain assumptions and differentiate between theoretical frameworkswhen dealing with knowledge work versus non-knowledge work. Research design, approach and method: This article offers a perspective of HR theory development over time. It is a conceptual/perspectives article and is not qualitative nor quantitative in nature. Further research will be able to test the ideas presented here. Practical/managerial implications: Managers and human resources managers need to differentiate between knowledge and non-knowledge work. The latter is associated with increased heterogeneity and complexity, and differences in power relationships, as knowledge work shifts power away from capital into the hands of skilled knowledge labour.

    Part I of this study deals with the right to know or not to know personal genetic information, and examines available legal protections of the right of privacy and the adverse effect of the disclosure of genetic information both on employment and insurance interests and on self esteem and protection of personal integrity. The study examines the rationale for the legal protection of privacy as the protection of a public interest. It examines the very limited protections currently available for privacy interests, including genetic privacy interests, and concludes that there is a need for broader, more far-reaching legal protections. The second part of the study is based on the assumption that as major a project as the Human Genome Project, spending billions of dollars on science which is health related, will indeed be applied for preventive and therapeutic public health purposes, as it has been in the past. It also addresses the recurring fear that public health initiatives in the genetic area must evolve a new eugenic agenda, that we must not repeat the miserable discriminatory experiences of the past.

  19. Human strongyloidiasis: identifying knowledge gaps, with emphasis on environmental control

    Full Text Available Michael J Taylor, Tara A Garrard, Francis J O'Donahoo, Kirstin E Ross Health and Environment, School of the Environment, Flinders University, Adelaide, SA, Australia Abstract: Strongyloides is a human parasitic nematode that is poorly understood outside a clinical context. This article identifies gaps within the literature, with particular emphasis on gaps that are hindering environmental control of Strongyloides. The prevalence and distribution of Strongyloides is unclear. An estimate of 100–370 million people infected worldwide has been proposed; however, inaccuracy of diagnosis, unreliability of prevalence mapping, and the fact that strongyloidiasis remains a neglected disease suggest that the higher figure of more than 300 million cases is likely to be a more accurate estimate. The complexity of Strongyloides life cycle means that laboratory cultures cannot be maintained outside of a host. This currently limits the range of laboratory-based research, which is vital to controlling Strongyloides through environmental alteration or treatment. Successful clinical treatment with antihelminthic drugs has meant that controlling Strongyloides through environmental control, rather than clinical intervention, has been largely overlooked. These control measures may encompass alteration of the soil environment through physical means, such as desiccation or removal of nutrients, or through chemical or biological agents. Repeated antihelminthic treatment of individuals with recurrent strongyloidiasis has not been observed to result in the selection of resistant strains; however, this has not been explicitly demonstrated, and relying on such assumptions in the long-term may prove to be shortsighted. It is ultimately naive to assume that continued administration of antihelminthics will be without any negative long-term effects. In Australia, strongyloidiasis primarily affects Indigenous communities, including communities from arid central Australia. This

    2006-01-01

    The nuclear industry is knowledge based, similar to other highly technical industries, and relies heavily on the accumulation of knowledge. Recent trends such as workforce ageing and declining student enrolment numbers, and the risk of losing accumulated knowledge and experience, have drawn attention to the need for better management of nuclear knowledge. In 2002 the IAEA General Conference adopted a resolution on nuclear knowledge, which was reiterated in 2003; the resolution emphasized the importance of nuclear knowledge and information management and urged both the IAEA and Member States to strengthen their activities and efforts in this regard. Consequently, the International Conference on Nuclear Knowledge Management: Strategies, Information Management and Human Resource Development, which was held on 7-10 September 2004 in Saclay, was organized by the IAEA and the Government of France through the Commissariat a l'energie atomique in cooperation with the European Commission, OECD Nuclear Energy Agency, European Atomic Forum, Japan Atomic Industrial Forum, World Council of Nuclear Workers, World Nuclear University and European Association of Information Services. The conference was attended by 250 experts, scientists and officials from 54 Member States and nine international organizations, giving the conference a very broad representation of the nuclear sector. The objective of the conference was to reach a clear and common understanding of the issues related to nuclear knowledge management for sustaining knowledge and expertise in nuclear science and technology and to define a strategic framework for developing IAEA cross-cutting knowledge management activities. The conference provided a forum for professionals and decision makers in the nuclear sector, comprising industry, government and academia, as well as professionals in the knowledge management and information technology sectors. Based on the results of the conference, the key insights, lessons learned

    Background: The objective of this study is to determine the influence of dental students’ knowledge and attitude regarding human papillomavirus infection of cervical cancer on willingness to pay for vaccination. Basic research design: A convenience sampling method was used. The minimal sample size of 136 was calculated using the Raosoft calculator with a 5 % margin of error and 95% confidence level. Participants: The study population were all final year dental students from the School of Dentistry. Methods: A self-administered questionnaire was used to measure knowledge levels and attitudes regarding human papillomavirus vaccination. Contingent valuation was conducted for willingness to pay for vaccination. Main outcome measures: The Center for Disease Control and Prevention has stated that human papillomavirus are associated with oropharynx cancer and the American Dental Association insist on expanding public awareness of the oncogenic potential of some HPV infections. Thus, as future dental practitioners, dental students should be aware of human papillomavirus and their links with cancer and the benefits of vaccination. Results: Knowledge on HPV and cervical cancer did not impact on attitudes towards vaccines. However, significant correlation existed between knowledge and willingness to pay for vaccination. Conclusions: Dental students’ knowledge on HPV and cervical cancer has no influence on their attitude towards HPV vaccines. However, their willingness to pay for HPV vaccination is influenced by their knowledge of cervical cancer and HPV vaccination. Creative Commons Attribution License

    To evaluate the knowledge, perception and attitudes towards human papilloma virus (HPV) among pre-university students in Malaysia. In this cross sectional study, between November 2013 to March 2014, in a public university, a convenient sampling method was used. A total of 716 respondents were recruited and interviewed with a set of standard questionnaires for assessment of knowledge, perception and attitudes towards HPV and predictor variables associated with level of knowledge. Almost half (48.9%) of the respondents scored less than 5 and were categorised as having poor knowledge. Three hundred and twelve (43.6%) respondents had moderate knowledge and only 54 (7.5%) respondents exhibited good knowledge with the score of 11 and above. Only 142 (20%) students perceived themselves to be vulnerable to HPV infection though 560 (78.2%) students thought that HPV infection is a serious disease. Perceived benefits and desire to be vaccinated were significantly associated with gender (p=0.000) and knowledge of HPV vaccine and cervical cancer (p=0.000). The level of knowledge regarding HPV among the pre-university students was low. However, student intention for vaccination increased with increasing level of knowledge. Thus, efforts to improve knowledge and awareness should be prioritised to increase uptake of the HPV vaccination programme and hence reduce morbidity and mortality from consequences of HPV infection, including cervical carcinoma.

    Human papillomavirus (HPV) is transmitted through sexual contact and can cause cervical cancer. The aim of this study was to determine knowledge, behaviors, and attitudes about human papillomavirus (HPV) in nursing students in a baccalaureate program. This study was conducted with a sample of 624 students. Data were collected via questionnaires administered during the first class time. Students' knowledge about HPV was high; 90.5% knew HPV can cause cervical cancer; 94.6% recognized it as a sexually transmitted disease. Although; 87.7% stated a vaccine is available to protect women from HPV, nearly all participants (98.1%) had not received HPV vaccination. Findings show students' level of knowledge about HPV's risk factors and modes of transmission were high. However, this knowledge did not translate into engagement in health related behaviors such as being vaccinated against HPV.

    During the 1970s, a growing number of medical schools began to recognize the importance of medical education concerning human sexuality. Currently, most medical schools provide at least some instruction in human sexuality. In light of this development, the present study aimed to compare the interest in and knowledge about human sexuality of medical students from two different time periods. The answers to a self-constructed questionnaire of 236 students in 1972 were compared with those of 259 students in 2012. Students were asked whether they were interested in education regarding human sexuality and which specific topics they felt should be included in the medical curriculum. The students' knowledge in the following domains was assessed: sexual development, sexual behavior, sexual physiology and psychology, and sexual medicine. The two cohorts were compared with regard to those specific sexuality-related topics in which the students were most and least interested in. Furthermore, the number of correct responses to the knowledge questions was compared. While in 1972, 99.2% of the students were interested in medical education about human sexuality, in 2012, 80.3% showed an interest. The connection of disorders from different medical disciplines with sexuality was rated as most interesting by both the students from 1972 and 2012. Medical students from 2012 gave 50.3% correct answers to the knowledge questions, whereas students from 1972 correctly answered 46.3% of the questions. Although interest in education concerning human sexuality has decreased, the majority of students view it as an important topic. Nevertheless, medical students still lack knowledge about important aspects of human sexuality (e.g., psychosexual development and relative safety of different contraceptives). Therefore, more time should be dedicated to education concerning human sexuality and its cultural, societal, and health aspects in particular. © 2014 International Society for Sexual Medicine.

    Full Text Available Today the human resources are seen as a very valuable asset to achieve long-term performance. Today we understand that every employee is required to learn throughout life, so to acquire new knowledge, to process such knowledge and possibly disseminate expertise with other members of the organization. The theory on human resources in various organizations has changed over time; recommendations have become more numerous, but there is no consensus on the subject. In other words, the permanent change which defines the competitive environment of business remains a type of constant when analysing the efficiency of human resources within companies; inter-individual relations (formal and informal and the values to which each employee relates remains crucial for any theoretical construction in this area. Principles and strategies applied by organizations yesterday could prove their inefficiency today; human resource strategies in organizations today should include a separate subcomponent, we believe, i.e. knowledge management (KM strategy. This is because the competitive advantage obtained or maintained by the company depends today, in large proportion, on the type, quality and value of knowledge possessed by the organization. Therefore, organizational strategy and thus the strategy of acquisition, developing and rewarding of human resources (HR should take into account this reality from the global environment. Moreover, in the current knowledge-driven economy, organizations must know how to develop and implement knowledge-based strategies to drive measurable business results. The goal of this paper is to describe a potential relation between the overall company strategy, HR strategy and KM strategy.

    2010-05-01

    In Europe a major recent development has been the entering in force of the INSPIRE Directive in May 2007, establishing an infrastructure for spatial information in Europe to support Community environmental policies, and policies or activities which may have an impact on the environment. INSPIRE is based on the infrastructures for spatial information established and operated by the 27 Member States of the European Union. The Directive addresses 34 spatial data themes needed for environmental applications, with key components specified through technical implementing rules. This makes INSPIRE a unique example of a legislative "regional" approach. One of the requirements of the INSPIRE Directive is to make existing spatial data sets with relevance for one of the spatial data themes available in an interoperable way, i.e. where the spatial data from different sources in Europe can be combined to a coherent result. Since INSPIRE covers a wide range of spatial data themes, the first step has been the development of a modelling framework that provides a common foundation for all themes. This framework is largely based on the ISO 19100 series of standards. The use of common generic spatial modelling concepts across all themes is an important enabler for interoperability. As a second step, data specifications for the first set of themes has been developed based on the modelling framework. The themes include addresses, transport networks, protected sites, hydrography, administrative areas and others. The data specifications were developed by selected experts nominated by stakeholders from all over Europe. For each theme a working group was established in early 2008 working on their specific theme and collaborating with the other working groups on cross-theme issues. After a public review of the draft specifications starting in December 2008, an open testing process and thorough comment resolution process, the draft technical implementing rules for these themes have been

    To analyze the relationship between the level of knowledge about human papilloma virus and the acceptance of vaginal self-sampling as a cervical cancer diagnostic test among Mexican women who have already experienced vaginal self-sampling at home. A structured questionnaire consisting of 22 questions was applied to 690 women in the state of Morelos who had taken a vaginal self-sample at home. The aspects explored were the level of knowledge about transmission of the human papilloma virus, identification of the virus as a necessary cause of cervical cancer, and clinical manifestations of infection and treatment. A knowledge index was constructed, identifying the relationship between the index and the women's acceptance of self-sampling, and their degree of trust in the procedure. The statistical analysis included a logistic regression with estimates of measures of association and their respective 95% confidence intervals. The level of knowledge about human papillomavirus showed a positive association with the degree of acceptance of vaginal self-sampling (OR 2.9; 95% CI 1.0-5.01) and the women's level of confidence (OR 2.9; 95% CI 1.8-4.67). The level of knowledge increased with level of education and was higher in younger women. In order for women with an increased risk of cervical cancer to continue participating in vaginal self-sampling, they must be well informed about the virus. This is especially true for older women, those with lower levels of education, and those in lower socioeconomic levels.

    This study considers the technological change that has occurred in complex systems within the past 30 years. The role of human operators in controlling and interacting with complex systems following the technological change was also investigated. Modernization of instrumentation and control systems and components leads to a new issue of human-automation interaction, in which human operational performance must be considered in automated systems. The human-automation interaction can differ in its types and levels. A system design issue is usually realized: given these technical capabilities, which system functions should be automated and to what extent? A good automation design can be achieved by making an appropriate human-automation function allocation. To our knowledge, only a few studies have been published on how to achieve appropriate automation design with a systematic procedure. Further, there is a surprising lack of information on examining and validating the influences of levels of automation (LOAs) on instrumentation and control systems in the advanced control room (ACR). The study we present in this paper proposed a systematic framework to help in making an appropriate decision towards types of automation (TOA) and LOAs based on a 'Skill-Rule-Knowledge' (SRK) model. From the evaluating results, it was shown that the use of either automatic mode or semiautomatic mode is insufficient to prevent human errors. For preventing the occurrences of human errors and ensuring the safety in ACR, the proposed framework can be valuable for making decisions in human-automation allocation.

    The motto of the 2012 Olympic and Paralympic Games is ‘Inspire a generation’ so it was particularly pleasing to see science, the LHC and Higgs bosons featuring so strongly in the opening ceremony of the Paralympics last week.   It’s a sign of just how far our field has come that such a high-profile event featured particle physics so strongly, and we can certainly add our support to that motto. If the legacy of London 2012 is a generation inspired by science as well as sport, then the games will have more than fulfilled their mission. Particle physics has truly inspiring stories to tell, going well beyond Higgs and the LHC, and the entire community has played its part in bringing the excitement of frontier research in particle physics to a wide audience. Nevertheless, we cannot rest on our laurels: maintaining the kind of enthusiasm for science we witnessed at the Paralympic opening ceremony will require constant vigilance, and creative thinking about ways to rea...

    2017-09-01

    Full Text Available Six Sigma (SS is a production philosophy focused on human experiences and knowledge, aimed to minimize defects of products and services. The appropriate implementation of SS requires an education process, reliable data analysis, efficient didactic material, statistical techniques and human knowledge to improve communication and operational benefits. In this article, we present a structural equation model integrating those aspects as latent variables and relating them with ten hypotheses. Data for hypothesis validation were gathered among 301 manufacturing companies, and assessed using partial least squares (PLS to estimate direct, indirect, and total effects. As results, we found that access to reliable information, trusted analysis and knowledgeable management are crucial for SS implementation at the problem definition stage. Likewise, to execute and control SS projects, it is important to be trained in statistical techniques through clear didactic materials.

    2017-08-01

    To clarify the potential value of a targeted system of human resource (HR) practices, we explore the unique effects of a relationship-oriented HR system and the more commonly studied high commitment HR system on unit performance in the context of knowledge-intensive work. We develop theoretical arguments suggesting that the high commitment HR system contributes to unit performance through its positive effects on employees' collective organizational commitment, general and firm-specific human capital, and access to knowledge. We argue that the relationship-oriented HR system contributes to unit performance through its positive effects on employees' collective access to knowledge by fostering a social context and interpersonal exchange conditions which support employees' ongoing access to knowledge flows within and outside their unit and broader organization. Based on unit-level data collected from a matched sample of employees and managers in 128 units in the science and engineering division of a large hydroelectric power organization, our results suggest that the targeted, relationship-oriented HR system is related to firm performance and may complement a broader, high commitment approach to managing knowledge workers. Specifically, the positive relationship between the high commitment HR system and unit performance is mediated by employees' collective organizational commitment, firm-specific human capital, and access to knowledge in other organizational units; whereas the positive relationship between the relationship-oriented HR system and unit performance is mediated by units' access to knowledge within the unit, in other units, and outside the organization.

    Full Text Available Knowledge about cervical cancer (CC risk factors and benefits of CC prevention motivates women to participate in its screening. However, several studies show that there is a significant knowledge deficit worldwide about human papillomavirus (HPV. The current study explores the level of knowledge about HPV and CC prevention in the context of sociodemographic and behavioral characteristics of women who visited an antenatal clinic in Arkhangelsk, Russia.This cross-sectional study was conducted in the city of Arkhangelsk, which seats the administrative center of Arkhangelsk County, Northwest Russia. It included women who consulted a gynecologist for any reason between January 1, 2015 and April 30, 2015, were residents of Arkhangelsk, 25 to 65 years of age and sexually active (N = 300. Student's t-test for continuous variables and Pearson's χ2 test for categorical variables were used in the comparisons of women grouped as having either poor or sufficient knowledge. Linear regression analysis was also employed.The level of knowledge about HPV and CC prevention was associated with education, parity, age of initiating of intercourse, and sources of information. After adjustment, women with university education were more likely to have higher knowledge about HPV and CC prevention compared to those with lower education.We observed that most participants had a sufficient level of knowledge. Educational gaps were identified that potentially could be used to tailor interventions in CC prevention.

    Increasing prevalence of human papilloma virus (HPV) infection and its association with cervical cancer as a leading cause of death make it necessary to evaluate and improve the public knowledge, especially of university students, about this cause of disease. A cross-sectional study of knowledge and attitude of a total 669 students from Tabriz University of Medical Sciences was therefore performed with a modified validated questionnaire, arranged into 5 parts and containing 55 questions, in July 2011. Questions were directed to study socio-demographic characteristics of the participant, knowledge about HPV disease, transmission route, relationship with cervical cancer, predisposing factors, and participants attitude toward people with HPV infection. All of the participants were Moslem with a mean age 25.6±5.33 years of age. All of the participants had heard of HPV, and acquired their knowledge through university courses (90.6%); the majority of them knew that HPV is a sexually transmitted disease and a potential cause for genital warts but general knowledge about details was not high. Mean knowledge score of residents and post graduate midwifery and nursing students was high as compared to other groups (Plevel (β=0.21, Pknowledge. Moderate level of knowledge about HPV among medical university students makes it necessary to set effective national public health efforts on HPV education and prevention considering he excess of young population in Iran vulnerable to cervical cancer.

    Improving the surveillance capacity over wide zones requires a set of smart battery-powered Unattended Ground Sensors capable of issuing an alarm to a decision-making center. Only high-level information has to be sent when a relevant suspicious situation occurs. In this paper we propose an innovative bio-inspired approach that mimics the human bi-modal vision mechanism and the parallel processing ability of the human brain. The designed prototype exploits two levels of analysis: a low-level panoramic motion analysis, the peripheral vision, and a high-level event-focused analysis, the foveal vision. By tracking moving objects and fusing multiple criteria (size, speed, trajectory, etc.), the peripheral vision module acts as a fast relevant event detector. The foveal vision module focuses on the detected events to extract more detailed features (texture, color, shape, etc.) in order to improve the recognition efficiency. The implemented recognition core is able to acquire human knowledge and to classify in real-time a huge amount of heterogeneous data thanks to its natively parallel hardware structure. This UGS prototype validates our system approach under laboratory tests. The peripheral analysis module demonstrates a low false alarm rate whereas the foveal vision correctly focuses on the detected events. A parallel FPGA implementation of the recognition core succeeds in fulfilling the embedded application requirements. These results are paving the way of future reconfigurable virtual field agents. By locally processing the data and sending only high-level information, their energy requirements and electromagnetic signature are optimized. Moreover, the embedded Artificial Intelligence core enables these bio-inspired systems to recognize and learn new significant events. By duplicating human expertise in potentially hazardous places, our miniature visual event detector will allow early warning and contribute to better human decision making.

    Full Text Available This research investigates the relationships between human knowledge, behavior and risk as they relate to urban chicken husbandry in the United States. Concern over zoonotic diseases has been on the rise, especially with increasing contact between birds and humans. In particular, avian influenza—or bird flu—and Salmonella enterica (Salmonella and Escherichia coli (E. coli can all cross species lines between people and poultry. This study analyzed knowledge and practices in urban chicken husbandry to assess how they relate to risk of disease acquisition, hypothesizing that certain practices associated with a lower knowledge base may heighten the risk. This study used a survey distributed via social media to examine the self-reported knowledge base of individuals involved in chicken husbandry as they relate to beliefs and behaviors associated with the care of these animals. These results identify key factors that may heighten the risk of disease transmission and demonstrate that an increased knowledge base could act to lessen this risk.

To date, histories of these fields have drawn on a number of fairly well-established punctuation marks to assist in periodization: the shift from interwar institutionalism in economics to postwar neoclassicism, with its physics-like emphasis on mathematical theory-building; the transition from the regnant prewar behaviorism through a postwar "cognitive revolution" in American psychology; and the move in fields like sociology and anthropology away from positivism and the pursuit of what has sometimes been called "grand theory" in the early postwar era toward a period defined by intellectual and political fragmentation, the reemergence of interpretive approaches and a reaction to the scientistic pretensions of the earlier period. These books, by contrast, provide perspectives orthogonal to such existing narrative frameworks by adopting cross-cutting lenses like the "Cold War" and the working practices of researchers in the social and behavioral sciences. As a result, they do much to indicate the value of casting a historiographical net beyond individual disciplines, or even beyond the "social sciences" or the "human sciences" sensu stricto, in the search for deeper patterns of historical development in these fields.

    What academics or books have inspired you in your writing and research, or helped to make sense of the world around you? In this feature essay, Ninna Meier returns to her experience of reading Hannah Arendt as she sought to understand work and how it relates to value production in capitalist...... economies. Meier recounts how Arendt’s book On Revolution (1963) forged connective threads between the ‘smallest parts’ and the ‘largest wholes’ and showed how academic work is never fully relegated to the past, but can return in new iterations across time....

  5. LncRNAWiki: harnessing community knowledge in collaborative curation of human long non-coding RNAs

    2014-11-15

    Long non-coding RNAs (lncRNAs) perform a diversity of functions in numerous important biological processes and are implicated in many human diseases. In this report we present lncRNAWiki (http://lncrna.big.ac.cn), a wiki-based platform that is open-content and publicly editable and aimed at community-based curation and collection of information on human lncRNAs. Current related databases are dependent primarily on curation by experts, making it laborious to annotate the exponentially accumulated information on lncRNAs, which inevitably requires collective efforts in community-based curation of lncRNAs. Unlike existing databases, lncRNAWiki features comprehensive integration of information on human lncRNAs obtained from multiple different resources and allows not only existing lncRNAs to be edited, updated and curated by different users but also the addition of newly identified lncRNAs by any user. It harnesses community collective knowledge in collecting, editing and annotating human lncRNAs and rewards community-curated efforts by providing explicit authorship based on quantified contributions. LncRNAWiki relies on the underling knowledge of scientific community for collective and collaborative curation of human lncRNAs and thus has the potential to serve as an up-to-date and comprehensive knowledgebase for human lncRNAs.

    About 5000 (25%) of the ~20400 human protein-coding genes currently lack any experimental evidence at the protein level. For many others, there is only little information relative to their abundance, distribution, subcellular localization, interactions, or cellular functions. The aim of the HUPO Human Proteome Project (HPP, www.thehpp.org ) is to collect this information for every human protein. HPP is based on three major pillars: mass spectrometry (MS), antibody/affinity capture reagents (Ab), and bioinformatics-driven knowledge base (KB). To meet this objective, the Chromosome-Centric Human Proteome Project (C-HPP) proposes to build this catalog chromosome-by-chromosome ( www.c-hpp.org ) by focusing primarily on proteins that currently lack MS evidence or Ab detection. These are termed "missing proteins" by the HPP consortium. The lack of observation of a protein can be due to various factors including incorrect and incomplete gene annotation, low or restricted expression, or instability. neXtProt ( www.nextprot.org ) is a new web-based knowledge platform specific for human proteins that aims to complement UniProtKB/Swiss-Prot ( www.uniprot.org ) with detailed information obtained from carefully selected high-throughput experiments on genomic variation, post-translational modifications, as well as protein expression in tissues and cells. This article describes how neXtProt contributes to prioritize C-HPP efforts and integrates C-HPP results with other research efforts to create a complete human proteome catalog.

    To investigate awareness and knowledge of human papillomavirus (HPV) infection among high school students and to provide a basis for health education on HPV infection for high school students in China. A questionnaire on HPV awareness and knowledge was administered to 900 high school students in Xiangtan City of Hunan Province in China by layer cluster sampling. A total of 848 anonymous valid questionnaires were received from volunteers who completed the questionnaire correctly. Only 10.1% had heard of HPV, and of those only 18.6% knew that HPV could lead to cervical cancer. Single factor analysis indicated that home address, age, grade, academic achievement, sex history, gender, father's education level and mother's education level were impact factors for HPV knowledge of high school students. Multiple regression analysis showed 4 independent risk factors associated with HPV knowledge: academic achievement, sex history, gender, and mother's education level. The limited knowledge came primarily from television and radio broadcasts (59.3%), the Internet (57.0%), parents (25.6%), medical workers (20.9%), and teachers (18.6%). High school students lack HPV knowledge, which is affected by multiple factors. Targeted health education of all sorts must be provided. Both schools and families are responsible for reinforcing HPV education provided to high school students.

    Adam Y Ye

    Full Text Available Transporters are essential in homeostatic exchange of endogenous and exogenous substances at the systematic, organic, cellular, and subcellular levels. Gene mutations of transporters are often related to pharmacogenetics traits. Recent developments in high throughput technologies on genomics, transcriptomics and proteomics allow in depth studies of transporter genes in normal cellular processes and diverse disease conditions. The flood of high throughput data have resulted in urgent need for an updated knowledgebase with curated, organized, and annotated human transporters in an easily accessible way. Using a pipeline with the combination of automated keywords query, sequence similarity search and manual curation on transporters, we collected 1,555 human non-redundant transporter genes to develop the Human Transporter Database (HTD (http://htd.cbi.pku.edu.cn. Based on the extensive annotations, global properties of the transporter genes were illustrated, such as expression patterns and polymorphisms in relationships with their ligands. We noted that the human transporters were enriched in many fundamental biological processes such as oxidative phosphorylation and cardiac muscle contraction, and significantly associated with Mendelian and complex diseases such as epilepsy and sudden infant death syndrome. Overall, HTD provides a well-organized interface to facilitate research communities to search detailed molecular and genetic information of transporters for development of personalized medicine.

    The Mars Program Planning Group (MPPG) was an agency wide effort, chartered in March 2012 by the NASA Associate Administrator for Science, in collaboration with NASA's Associate Administrator for Human Exploration and Operations, the Chief Scientist, and the Chief Technologist. NASA tasked the MPPG to develop foundations for a program-level architecture for robotic exploration of Mars that is consistent with the President's challenge of sending humans to the Mars system in the decade of the 2030s and responsive to the primary scientific goals of the 2011 NRC Decadal Survey for Planetary Science. The Mars Exploration Program Analysis Group (MEPAG) also sponsored a Precursor measurement Strategy Analysis Group (P-SAG) to revisit prior assessments of required precursor measurements for the human exploration of Mars. This paper will discuss the key results of the MPPG and P-SAG efforts to update and refine our understanding of the Strategic Knowledge Gaps (SKGs) required to successfully conduct human Mars missions.

    The beneficial effects of breastfeeding for mothers and babies are well recognized. When maternal breast milk is not available in sufficient quantity, donor breast milk is recommended as an alternate source of nutrition, particularly in preterm and other high-risk infants. Australia lags behind the rest of the developed world in establishing and promoting human milk banks; there is no human milk bank in South Australia and little is known concerning mothers' perceptions of using human milk banks in that state. This study explored mothers' knowledge of and attitudes toward human milk banks, to inform the development of human milk banking policies and guidelines in South Australia should a milk bank be established. In-depth semistructured interviews were conducted with 12 mothers who were breastfeeding and/or had preterm or sick babies. In addition, 2 focus groups were conducted-1 with breastfeeding mothers as potential donors (n = 5) and the other with mothers of preterm or high-risk infants (n = 4)-to answer questions raised by early analysis of the individual interview data. Breastfeeding mothers, as potential donors, unanimously supported donating their breast milk to a human milk bank, provided it would be easy (especially if required to drop off milk) and not overly time consuming. Mothers of preterm or sick infants would use a human milk bank if they were assured the milk was safe and appropriate for their babies. Study participants would welcome having access to a human milk bank for both donating and receiving milk in South Australia.

    Human papilloma virus (HPV) is one of the most common sexually transmitted agents and its infection is the most established cause of cervical cancer. Midwives play a key position in the implementation of cervical cancer. This descriptive study aimed to determine the level of knowledge concerning HPV and HPV vaccination among 268 midwifery students. Data were collected between November 15 and 30, 2011, through a self-reported questionnaire. The mean age of participants was 20.75 ± 1.60. Among all students, 44.4% had heard of HPV, while 40.4% had heard of HPV vaccinatiob. The relationship between the midwifery student knowledge on HPV and HPV vaccine and their current educational year was significant (p=0.001). In conclusion midwifery students have moderate level of knowledge about HPV and its vaccine and relevant information should be included in their teaching curriculum.

  15. IMPORTANCE OF THE HUMAN FACTOR IN THE KNOWLEDGE-BASED SOCIETY

    2016-02-01

    Full Text Available The paper approaches the paradigmatic changes of the current economic situation, in the context of post-modernism and its challenges, which reconsiders human society according to new criteria. One of the characteristics of post-modernism is the development of information and communication techniques, which allowed the occurrence of the „knowledge-based society” whose consequence is the effervescence of fast barrier-free knowledge, absolute freedom of debates, equality of opportunities before the virtual space, but also the relativisation of information, the increases of the danger of manipulation, misleading, or even falsification of the truth. New challenges occur thus in social life, and especially in the economic one, where the human factor becomes increasingly important for the evolution of society. In this context, education seems to play the decisive part, but an education focused on real values, where the truth and the ethics prevail before efficiency and performance.

    The words of a language reflect the structure of the human mind, allowing us to transmit thoughts between individuals. However, language can represent only a subset of our rich and detailed cognitive architecture. Here, we ask what kinds of common knowledge (semantic memory) are captured by word meanings (lexical semantics). We examine a prominent computational model that represents words as vectors in a multidimensional space, such that proximity between word-vectors approximates semantic re...

    2011-01-01

    This study aimed to characterize the challenges in using genetic information in health care and to identify opportunities for improvement. Taking a grounded theory approach, semistructured interviews were conducted with 48 participants to collect multiple stakeholder perspectives on genetic services in New Zealand. Three themes emerged from the data: (1) four service delivery models were identified in operation, including both those expected models involving genetic counselors and variations that do not route through the formal genetic service program; (2) multiple barriers to sharing and using genetic information were perceived, including technological, organizational, institutional, legal, ethical, and social issues; and (3) impediments to wider use of genetic testing technology, including variable understanding of genetic test utilities among clinicians and the limited capacity of clinical genetic services. Targeting these problems, information technologies and knowledge management tools have the potential to support key tasks in genetic services delivery, improve knowledge processes, and enhance knowledge networks. Because of the effect of issues in genetic information and knowledge management, the potential of human genetic variation knowledge to enhance health care delivery has been put on a "leash."

  2. Human Papillomavirus and students in Brazil: an assessment of knowledge of a common infection - preliminary report

    Directory of Open Access Journals (Sweden)

    João Cesar Frizzo Burlamaqui

    Full Text Available Abstract Introduction: Human Papillomavirus (HPV infection is the most prevalent sexually transmitted disease worldwide. One of the barriers to the implementation of prevention programs against the disease is the limited knowledge possessed by most populations regarding the virus and its possible consequences. Objective: The purpose of this study was to evaluate the knowledge of Brazilian college students on transmission, clinical manifestations, and diseases correlated with HPV, highlighting the poor knowledge of a very common infection. Methods: A total of 194 students answered a questionnaire about transmission, clinical features and the possible consequences of persistent HPV infection. The questionnaire was self-applied under the supervision of the authors. Results: The clinical manifestations of HPV infection were not clear to most students. Incorrect assumptions of the clinical manifestations of HPV infection included: bleeding (25%, pain (37% and rashes (22%. Twelve per cent of respondents did not recognize warts as an HPV-related disease. Regarding potential consequences of persistent infection, students did not recognize a relationship between HPV and laryngeal carcinoma (80.9%, pharyngeal carcinoma (78.9%, anal carcinoma (73.2%, vulvar carcinoma (65.4% and vaginal carcinoma (54.6%. Large portions of the population evaluated were unaware of modes of HPV transmission beyond genital contact. Conclusion: Knowledge of HPV by the population evaluated in this study is partial and fragmented. Lack of knowledge may contribute to the further spread of the disease. Public health policies for education and guidance of the population should be implemented in Brazil.

    Latinas have the highest incidence of cervical cancer, yet Latino parents/guardians' knowledge about and willingness to have their children receive the human papillomavirus (HPV) vaccine is unknown. Latino parents/guardians (N = 67) of children aged 11-17 were recruited from two community organizations to complete a survey, including HPV vaccine knowledge, child's uptake, demographic characteristics, and acculturation. Descriptive statistics and correlates of parents' HPV knowledge and uptake were calculated using Chi square tests and multivariable logistic regression. Receipt of at least one dose of the HPV vaccine was moderate for daughters (49.1%) and low for sons (23.4%). Parents/guardians reported limited knowledge as the main barrier to vaccine receipt. Among parents/guardians with vaccinated daughters, 92.6% did not know the vaccine requires three doses. Adjusting for income, low-acculturated parents were more likely than high-acculturated parents to report inadequate information (OR 8.59, 95% CI 2.11-34.92). Interventions addressing low knowledge and children's uptake of the HPV vaccine are needed among Latino parents/guardians.

    Full Text Available Objective. To compare knowledge and attitudes of human papillomavirus (HPV and the vaccine between different cultures of African descent. Methods. A cross-sectional survey of 555 African-Americans and Afro-Caribbeans residing in the US and the Bahamas (BHM was conducted. Results. General knowledge about HPV and the HPV vaccine differed between the two countries significantly. Bahamian respondents were less likely to have higher numbers of correct knowledge answers when compared to Americans (Adjusted Odds Ratio [Adj. OR] 0.47, 95% Confidence Interval [CI] 0.30–0.75. Older age, regardless of location, was also associated with answering fewer questions correctly (Adj. OR 0.61, 95% CI 0.40–0.92. Attitudes related to HPV vaccination were similar between the US and BHM, but nearly 80% of BHM respondents felt that children should not be able to receive the vaccine without parental consent compared to 57% of American respondents. Conclusions. Grave lack of knowledge, safety and cost concerns, and influence of parental restrictions may negatively impact vaccine uptake among African-American and Afro-Caribbean persons. Interventions to increase the vaccine uptake in the Caribbean must include medical provider and parental involvement. Effective strategies for education and increasing vaccine uptake in BHM are crucial for decreasing cervical cancer burden in the Caribbean.

    Body Worlds is an anatomical exhibition that shows human remains to the public. It has been considered controversial since it raises ethical tensions and issues. However, organizers and supporters of Body Worlds have claimed the exhibition is intended to promote visitors' understanding over the human body. Despite these claims, no studies were found that support or refute the hypothesis that a visit to Body Worlds increases the public's objective knowledge on human anatomy. Consequently, the objective of this study was to determine the impact of Body Worlds on anatomical knowledge. We constructed and delivered a questionnaire to both a previsit random sample and a postvisit random sample of visitors of Body Worlds' event Facets of Life, in Berlin. The questionnaire was available in both English and German languages and contained (a) basic sociodemographic questions and (b) a valid and reliable anatomy quiz. The quiz consisted of 16 multiple-choice questions that assessed the ability to identify the location of major anatomical structures on the human body. Average scores achieved on the quiz by the postvisit sample (X¯= 9.08, s = 2.48, n = 164) were significantly higher (unpaired t = 3.3957, P = 0.0008) than those achieved by the previsit sample (X¯= 8.11, s = 2.69, n = 167). Our results suggest that a visit to Body Worlds' event Facets of Life may have a beneficial effect in anatomical knowledge. However, further studies with better empirical designs and fewer limitations are needed to confirm our results. © 2016 Wiley Periodicals, Inc.

    Human papillomavirus (HPV) is one of the most common sexually transmitted infections in sexually active adolescents and young women and has been implicated as a cause of the majority of cases of cervical cancer, which is the second most common cancer in women in Nigeria. HPV is preventable with the use of HPV vaccines. The objective of this study was to assess mothers' HPV knowledge and their willingness to vaccinate their adolescent daughters in Lagos, Nigeria. This study was a community-based, descriptive cross-sectional study carried out in July, 2012 in Shomolu Local Government Area (LGA) of Lagos State, Nigeria. Multistage sampling method was employed to select the 290 respondents who participated in the study. Structured, pretested, interviewer-administered questionnaires were used for data collection. Data was analyzed with Epi Info™ version 7. The study revealed low awareness of HPV (27.9%) and HPV vaccines (19.7%) among the mothers that participated. There was a high awareness for cervical cancer but little knowledge of its link to HPV. Awareness and utilization of HPV vaccines increased with increasing educational level (P knowledge about HPV and HPV vaccines, mothers were willing to vaccinate their daughters. We recommend improving mothers' knowledge by education and the possible inclusion of the vaccine in the national immunization schedule to eliminate the financial barrier.

    The CHNRI method for setting health research priorities has crowdsourcing as the major component. It uses the collective opinion of a group of experts to generate, assess and prioritize between many competing health research ideas. It is difficult to compare the accuracy of human individual and collective opinions in predicting uncertain future outcomes before the outcomes are known. However, this limitation does not apply to existing knowledge, which is an important component underlying opinion. In this paper, we report several experiments to explore the quantitative properties of human collective knowledge and discuss their relevance to the CHNRI method. We conducted a series of experiments in groups of about 160 (range: 122-175) undergraduate Year 2 medical students to compare their collective knowledge to their individual knowledge. We asked them to answer 10 questions on each of the following: (i) an area in which they have a degree of expertise (undergraduate Year 1 medical curriculum); (ii) an area in which they likely have some knowledge (general knowledge); and (iii) an area in which they are not expected to have any knowledge (astronomy). We also presented them with 20 pairs of well-known celebrities and asked them to identify the older person of the pair. In all these experiments our goal was to examine how the collective answer compares to the distribution of students' individual answers. When answering the questions in their own area of expertise, the collective answer (the median) was in the top 20.83% of the most accurate individual responses; in general knowledge, it was in the top 11.93%; and in an area with no expertise, the group answer was in the top 7.02%. However, the collective answer based on mean values fared much worse, ranging from top 75.60% to top 95.91%. Also, when confronted with guessing the older of the two celebrities, the collective response was correct in 18/20 cases (90%), while the 8 most successful individuals among the

    Full Text Available This study is an effort to propose a conceptual model to measure the impact assessment of entrepreneurship pedagogic. It delineates entrepreneurship education pedagogic into four dimensions and opined specific level for each dimension. Reviewing the entrepreneurship education programme, assessment of entrepreneurship pedagogic evaluates the structure that influence growth mindset development through embedded heuristic strategies, thus, the impact on entrepreneurship knowledge and entrepreneurial capital asset context is proposed. Affirming Fayolle, Gailly, and Lassa-Clerc conceptual affinity that entrepreneurship education share with learning theories and entrepreneurship pedagogical content knowledge were conceptualized to suggest some practical realism guidelines of what insightful philosophy of teaching entrepreneurship need to achieve. With direct synthesis of relevant literature, propositions relating to entrepreneurship pedagogic structure along with the institutional connectedness and associated dimensions of entrepreneurship pedagogic assessment outcome were postulated. Also, the paper proposes the need for further assessment of specific forms of pedagogic impact on entrepreneurial human capital asset.

    This study aimed to ascertain the knowledge and attitudes of urban and rural dwellers to cervical cancer and HPV in Gwagwalada Area Council of Nigeria. 400 participants aged 15-45 years were selected from Gwagwalada town and the adjourning Giri village to respond to a multi-choice-free response questionnaire designed to obtain information on respondents' biodata, knowledge of STIs, human papilloma virus and cervical cancer, health and communication resources in their communities. This was supplemented by focus group discussions among religious and tribal groups within the urban and rural communities. We found a low level of awareness about HPV and cervical cancer which majority felt could not be prevented. Although awareness of STDs was high in both urban and rural dwellers, condom use was low. The study underscores the need for a well planned and implemented health communication and education program on STIs, HPV and cervical cancer in Nigeria.

    Full Text Available Human settlements are social-economic-natural complex ecosystems centered on human activities and the most prominent site for the contradictions between humans and the environment. Taking Hongcun, a UNESCO World Heritage site in China, as an example, this paper analyzes the methods and effect of coupling man and nature in Hongcun, summarizes the ecological wisdom of dealing with the relationship between human and nature, and uses this wisdom to shed light on the planning, construction, and management of contemporary urban and rural settlements. Firstly, the study introduces the Human-Natural Intergraded Ecological Planning (HNIEP model’s hypothesis, explaining its foundation and potential principles or approaches. Secondly, using the case study of Hongcun to explain, support, and validate the HNIEP model and its framework, the study found that the unique planning and construction of Hongcun has greatly promoted ecosystem services, such as local microclimate regulation, rainwater runoff regulation, water conservation, landscape aesthetic, and engagement with nature. Thirdly, Hongcun reflects the concept of harmonious coexistence between human and nature, the wisdom of rational use of ecosystem structures, processes and functions, and the wisdom of coupling human activities with the living environment and natural ecosystem. Finally, the paper summarizes the enlightenment brought by both the HNIEP model and Hongcun wisdom to contemporary urban-rural planning and construction management.

    Cognitive psychologists distinguish implicit, procedural category learning (stimulus-response associations learned outside declarative cognition) from explicit-declarative category learning (conscious category rules). These systems are dissociated by category learning tasks with either a multidimensional, information-integration (II) solution or a unidimensional, rule-based (RB) solution. In the present experiments, humans and two monkeys learned II and RB category tasks fostering implicit and explicit learning, respectively. Then they received occasional transfer trials-never directly reinforced-drawn from untrained regions of the stimulus space. We hypothesized that implicit-procedural category learning-allied to associative learning-would transfer weakly because it is yoked to the training stimuli. This result was confirmed for humans and monkeys. We hypothesized that explicit category learning-allied to abstract category rules-would transfer robustly. This result was confirmed only for humans. That is, humans displayed explicit category knowledge that transferred flawlessly. Monkeys did not. This result illuminates the distinctive abstractness, stimulus independence, and representational portability of humans' explicit category rules.

    Purpose The aim of this study was to determine Turkish women's knowledge, attitudes, and behaviors on wet-nursing, milk sharing, and human milk banking in a primary care setting located in a semi-rural area. Description Donated human milk is a feasible option for feeding infants and children. Currently, there is a debate on the topic starts with the preparations to launch a human milk bank in a large city in Turkey. Several previous papers reported women's opinions in large hospital based studies. Little is known about women's views and practice on donated human milk in the rural areas of Turkey. Assessment The study sample was recruited among married women aged 15-49 years who had given birth within the past 5 years and who were in a family health center for any reason in Honaz, Denizli, Turkey. A total of 240 women were included in the study. The data were collected by questionnaire created by the researchers and consisting of two parts: sociodemographic characteristics, and women's knowledge, attitudes, and behaviors on wet-nursing, milk sharing and human milk banking. Results Thirty women (12.5%) had had a wet-nurse; 20 women (8.7%) wet-nursed babies before; and 17 (7.2%) of the women's children had a wet-nurse. If necessary, 80.9 and 78.3% were willing to accept to do wet-nursing and milk sharing, respectively. 150 (62.5%) heard of human milk banks; 55 (22.9%) approved of the establishment of milk banks. However, only 46 women (19.1%) were willing to donate to the bank. Possibility of marriages between milk siblings (76.8%) was the main reason for not considering the donation. Women's education was another factor affecting their opinion on breast milk sharing and donation to human milk banks. Less educated women were sympathetic to milk sharing (p = 0.02), however, more educated mothers had a propensity to donate to milk banks (p = 0.02). Conclusion Wet-nursing decreased over the years in Turkey, but still an ongoing small child feeding method

    2013-04-01

    Over the past decade, there has been considerable interest in miniaturizing aircraft to create a class of extremely small, robotic vehicles with a gross mass on the order of tens of grams and a dimension on the order of tens of centimeters. These are collectively refered to as micro aerial vehicles (MAVs) or microflyers. Because the size of microflyers is on the same order as that of small birds and large insects, engineers are turning to nature for inspiration. Bioinspired concepts make use of structural or aerodynamic mechanisms that are observed in insects and birds, such as elastic energy storage and unsteady aerodynamics. Biomimetic concepts attempt to replicate the form and function of natural flyers, such as flapping-wing propulsion and external appearance. This paper reviews recent developments in the area of man-made microflyers. The design space for microflyers will be described, along with fundamental physical limits to miniaturization. Key aerodynamic phenomena at the scale of microflyers will be highlighted. Because the focus is on bioinspiration and biomimetics, scaled-down versions of conventional aircraft, such as fixed wing micro air vehicles and microhelicopters will not be addressed. A few representative bioinspired and biomimetic microflyer concepts developed by researchers will be described in detail. Finally, some of the sensing mechanisms used by natural flyers that are being implemented in man-made microflyers will be discussed.

  19. Inspired by CERN

    2004-01-01

    Art students inspired by CERN will be returning to show their work 9 to 16 October in Building 500, outside the Auditorium. Seventeen art students from around Europe visited CERN last January for a week of introductions to particle physics and astrophysics, and discussions with CERN scientists about their projects. A CERN scientist "adopted"each artist so they could ask questions during and after the visit. Now the seeds planted during their visit have come to fruition in a show using many media and exploring varied concepts, such as how people experience the online world, the sheer scale of CERN's equipment, and the abstractness of the entities scientists are looking for. "The work is so varied, people are going to love some pieces and detest others," says Andrew Charalambous, the project coordinator from University College London who is also curating the exhibition. "It's contemporary modern art, and that's sometimes difficult to take in." For more information on this thought-provoking show, see: htt...

    Full Text Available We constructed an 11-arm, walk-through, human radial-arm maze (HRAM as a translational instrument to compare existing methodology in the areas of rodent and human learning and memory research. The HRAM, utilized here, serves as an intermediary test between the classic rat radial-arm maze (RAM and standard human neuropsychological and cognitive tests. We show that the HRAM is a useful instrument to examine working memory ability, explore the relationships between rodent and human memory and cognition models, and evaluate factors that contribute to human navigational ability. One-hundred-and-fifty-seven participants were tested on the HRAM, and scores were compared to performance on a standard cognitive battery focused on episodic memory, working memory capacity, and visuospatial ability. We found that errors on the HRAM increased as working memory demand became elevated, similar to the pattern typically seen in rodents, and that for this task, performance appears similar to Miller’s classic description of human working memory capacity of 7±2 items. Regression analysis revealed that measures of working memory capacity and visuospatial ability accounted for a large proportion of variance in HRAM scores, while measures of episodic memory and general intelligence did not serve as significant predictors of HRAM performance. We present the HRAM as a novel instrument for measuring navigational behavior in humans, as is traditionally done in basic science studies evaluating rodent learning and memory, thus providing a useful tool to help connect and translate between human and rodent models of cognitive functioning.

    Eclipse maps are a unique vessel of knowledge. At a glance, they communicate the essential knowledge of where and when to successfully view a total eclipse of the sun. An eclipse map also provides detailed knowledge of eclipse circumstances superimposed on the highway system for optimal navigation, especially in the event that weather forces relocation. Eclipse maps are also a vital planning tool for solar physicists and astrophotographers capturing high-resolution imagery of the solar corona. Michael Zeiler will speak to the role of eclipse maps in educating the American public and inspiring people to make the effort to reach the path of totality for the sight of a lifetime. Michael will review the role of eclipse maps in astronomical research and discuss a project under development, the 2017 Eclipse Atlas for smartphones, tablets, and desktop computers.

  2. A knowledge based approach to matching human neurodegenerative disease and animal models

    Full Text Available Neurodegenerative diseases present a wide and complex range of biological and clinical features. Animal models are key to translational research, yet typically only exhibit a subset of disease features rather than being precise replicas of the disease. Consequently, connecting animal to human conditions using direct data-mining strategies has proven challenging, particularly for diseases of the nervous system, with its complicated anatomy and physiology. To address this challenge we have explored the use of ontologies to create formal descriptions of structural phenotypes across scales that are machine processable and amenable to logical inference. As proof of concept, we built a Neurodegenerative Disease Phenotype Ontology and an associated Phenotype Knowledge Base using an entity-quality model that incorporates descriptions for both human disease phenotypes and those of animal models. Entities are drawn from community ontologies made available through the Neuroscience Information Framework and qualities are drawn from the Phenotype and Trait Ontology. We generated ~1200 structured phenotype statements describing structural alterations at the subcellular, cellular and gross anatomical levels observed in 11 human neurodegenerative conditions and associated animal models. PhenoSim, an open source tool for comparing phenotypes, was used to issue a series of competency questions to compare individual phenotypes among organisms and to determine which animal models recapitulate phenotypic aspects of the human disease in aggregate. Overall, the system was able to use relationships within the ontology to bridge phenotypes across scales, returning non-trivial matches based on common subsumers that were meaningful to a neuroscientist with an advanced knowledge of neuroanatomy. The system can be used both to compare individual phenotypes and also phenotypes in aggregate. This proof of concept suggests that expressing complex phenotypes using formal

    Nature still outperforms the most powerful computers in routine functions involving perception, sensing and actuation like vision, audition, and motion control, and is, most strikingly, orders of magnitude more energy-efficient than its artificial competitors. The reasons for the superior performance of biological systems are subject to diverse investigations, but it is clear that the form of hardware and the style of computation in nervous systems are fundamentally different from what is used in artificial synchronous information processing systems. Very generally speaking, biological neural systems rely on a large number of relatively simple, slow and unreliable processing elements and obtain performance and robustness from a massively parallel principle of operation and a high level of redundancy where the failure of single elements usually does not induce any observable system performance degradation. In the late 1980's, Carver Mead demonstrated that silicon VLSI technology can be employed in implementing ''neuromorphic'' circuits that mimic neural functions and fabricating building blocks that work like their biological role models. Neuromorphic systems, as the biological systems they model, are adaptive, fault-tolerant and scalable, and process information using energy-efficient, asynchronous, event-driven methods. In this paper, some basics of neuromorphic electronic engineering and its impact on recent developments in optical sensing and artificial vision are presented. It is demonstrated that bio-inspired vision systems have the potential to outperform conventional, frame-based vision acquisition and processing systems in many application fields and to establish new benchmarks in terms of redundancy suppression/data compression, dynamic range, temporal resolution and power efficiency to realize advanced functionality like 3D vision, object tracking, motor control, visual feedback loops, etc. in real-time. It is argued that future artificial vision systems

    Introduction: Human papillomavirus (HPV), belonging to the Papovavirida family, is the most prevalent sexually transmitted disease (STD) agent worldwide. In Brazil, it is estimated that there are 3-6 million people infected with HPV. Aim: The aim of this study was to evaluate the knowledge of young male students about penis cancer related to HPV infection. Methods: This exploratory and quantitative study was conducted to analyze answers of 242 male students attending a private college located in Uberaba city, Minas Gerais state, Brazil, during 2015. Results: Most of the 242 participants (88.8%) affirmed having started sexual life very early, the majority (79.3%) were currently married and 69.8% had a single sexual partner. Regardless of their knowledge about HPV virus and its relationship with penis cancer, our data showed a general lack of awareness of the participants. Conclusion: Our results suggest that despite efforts to propagate information about HPV infection and its relation to penis cancer, the level of knowledge of students is low. Because of that, it is important to improve the information spread by media, emphasizing prevention and treatment of HPV infection in men. Creative Commons Attribution License

    Full Text Available This study develops a model for knowledge socialization using sociability processes of human resources through an applied research approach. Two types of participants participated in this study. The first type included academic and industrial experts; the second type included employees and managers of Ansar Bank. Ten experts were asked to identify criteria and weigh the identified criteria. Using simple random sampling, the sample size was estimated at 207. Field and archival studies were used to collect data. Validity and reliability of the distributed questionnaire were confirmed by organizational experts. Using theoretical literature and surveying experts, 18 criteria were identified of which 12 criteria (desirable and joyful workplace, management and leadership support in sociability process, training courses, transparency in working relations, team work, organizational trustful climate, job description and job knowledge, tangible incentives, participatory system, informal technique, defined career path, individual values aligned with organizational value were selected by screening for prioritization and analysis. Fuzzy AHP and structural equation modelling based on partial least squares were used for prioritization and weighting. Fuzzy AHP model showed that desirable workplace (0.163, participatory systems and brainstorming (0.149, transparency in working relations (0.114, and informal techniques (0.111 gained the highest weights; finally, PLS model showed that all 12 identified criteria were effective on socialization of knowledge management.

    This report provides a summary of a programme of work, commissioned within the BIOPROTA collaborative forum, to assess the quantitative and qualitative elements of uncertainty associated with biota dose assessment of potential impacts of long-term releases from geological disposal facilities (GDF). Quantitative and qualitative aspects of uncertainty were determined through sensitivity and knowledge quality assessments, respectively. Both assessments focused on default assessment parameters within the ERICA assessment approach. The sensitivity analysis was conducted within the EIKOS sensitivity analysis software tool and was run in both generic and test case modes. The knowledge quality assessment involved development of a questionnaire around the ERICA assessment approach, which was distributed to a range of experts in the fields of non-human biota dose assessment and radioactive waste disposal assessments. Combined, these assessments enabled critical model features and parameters that are both sensitive (i.e. have a large influence on model output) and of low knowledge quality to be identified for each of the three test cases. The output of this project is intended to provide information on those parameters that may need to be considered in more detail for prospective site-specific biota dose assessments for GDFs. Such information should help users to enhance the quality of their assessments and build greater confidence in the results. (orig.)

    To create subjective experience, our brain must translate physical stimulus input by incorporating prior knowledge and expectations. For example, we perceive color and not wavelength information, and this in part depends on our past experience with colored objects ( Hansen et al. 2006; Mitterer and de Ruiter 2008). Here, we investigated the influence of object knowledge on the neural substrates underlying subjective color vision. In a functional magnetic resonance imaging experiment, human subjects viewed a color that lay midway between red and green (ambiguous with respect to its distance from red and green) presented on either typical red (e.g., tomato), typical green (e.g., clover), or semantically meaningless (nonsense) objects. Using decoding techniques, we could predict whether subjects viewed the ambiguous color on typical red or typical green objects based on the neural response of veridical red and green. This shift of neural response for the ambiguous color did not occur for nonsense objects. The modulation of neural responses was observed in visual areas (V3, V4, VO1, lateral occipital complex) involved in color and object processing, as well as frontal areas. This demonstrates that object memory influences wavelength information relatively early in the human visual system to produce subjective color vision. © The Author 2014.

    The Human Genome Project (HGP) was initiated in 1990 and completed in 2003. It aimed to sequence the whole human genome. Although it represented an advance in understanding the human genome and its complexity, many questions remained unanswered. Other projects were launched in order to unravel the mysteries of our genome, including the ENCyclopedia of DNA Elements (ENCODE). This review aims to analyze the evolution of scientific knowledge related to both the HGP and ENCODE projects. Data were retrieved from scientific articles published in 1990-2014, a period comprising the development and the 10 years following the HGP completion. The fact that only 20,000 genes are protein and RNA-coding is one of the most striking HGP results. A new concept about the organization of genome arose. The ENCODE project was initiated in 2003 and targeted to map the functional elements of the human genome. This project revealed that the human genome is pervasively transcribed. Therefore, it was determined that a large part of the non-protein coding regions are functional. Finally, a more sophisticated view of chromatin structure emerged. The mechanistic functioning of the genome has been redrafted, revealing a much more complex picture. Besides, a gene-centric conception of the organism has to be reviewed. A number of criticisms have emerged against the ENCODE project approaches, raising the question of whether non-conserved but biochemically active regions are truly functional. Thus, HGP and ENCODE projects accomplished a great map of the human genome, but the data generated still requires further in depth analysis. © 2016 by The International Union of Biochemistry and Molecular Biology, 44:215-223, 2016. © 2016 The International Union of Biochemistry and Molecular Biology.

HPV is preventable with the use of HPV vaccines. Objectives: The objective of this study was to assess mothers' HPV knowledge and their willingness to vaccinate their adolescent daughters in Lagos, Nigeria. Materials and methods: This study was a community-based, descriptive cross-sectional study carried out in July, 2012 in Shomolu Local Government Area (LGA of Lagos State, Nigeria. Multistage sampling method was employed to select the 290 respondents who participated in the study. Structured, pretested, interviewer-administered questionnaires were used for data collection. Data was analyzed with Epi-Info™ version 7. Results: The study revealed low awareness of HPV (27.9% and HPV vaccines (19.7% among the mothers that participated. There was a high awareness for cervical cancer but little knowledge of its link to HPV. Awareness and utilization of HPV vaccines increased with increasing educational level (P<0.05. There was a high willingness and intention among the mothers to vaccinate their girls (88.9% and to recommend the vaccine to others (91.0%. Accessibility and affordability of the HPV vaccines were found to be possible barriers to future utilization of the vaccines. Conclusion: Despite low knowledge about HPV and HPV vaccines, mothers were willing to vaccinate their daughters. We recommend improving mothers' knowledge by education and the possible inclusion of the vaccine in the national immunization

    To prevent onset of age-related diseases and physical and cognitive decline, interventions to slow human aging and extend health span must eventually be applied to people while they are still young and healthy. Yet most human aging research examines older adults, many with chronic disease, and little is known about aging in healthy young humans. This article explains how this knowledge gap is a barrier to extending health span and puts forward the case that geroscience should invest in researching the pace of aging in young adults. As one illustrative example, we describe an initial effort to study the pace of aging in a young-adult birth cohort by using repeated waves of biomarkers collected across the third and fourth decades to quantify the pace of coordinated physiological deterioration across multiple organ systems (eg, pulmonary, periodontal, cardiovascular, renal, hepatic, metabolic, and immune function). Findings provided proof of principle that it is possible to quantify individual variation in the pace of aging in young adults still free of age-related diseases. This article articulates research needs to improve longitudinal measurement of the pace of aging in young people, to pinpoint factors that slow or speed the pace of aging, to compare pace of aging against genomic clocks, to explain slow-aging young adults, and to apply pace of aging in preventive clinical trials of antiaging therapies. This article puts forward a research agenda to fill the knowledge gap concerning lifelong causes of aging. © The Author 2016.

    Nacre-inspired nanocomposites with excellent mechanical properties have achieved remarkable attention in the past decades. The high performance of nacre-inspired nanocomposites is a good basis for the further application of smart devices. Recently, some smart nanocomposites inspired by nacre have demonstrated good mechanical properties as well as effective and stable stimuli-responsive functions. In this Concept, we summarize the recent development of smart nacre-inspired nanocomposites, including 1D fibers, 2D films and 3D bulk nanocomposites, in response to temperature, moisture, light, strain, and so on. We show that diverse smart nanocomposites could be designed by combining various conventional fabrication methods of nacre-inspired nanocomposites with responsive building blocks and interface interactions. The nacre-inspired strategy is versatile for different kinds of smart nanocomposites in extensive applications, such as strain sensors, displays, artificial muscles, robotics, and so on, and may act as an effective roadmap for designing smart nanocomposites in the future. © 2018 Wiley-VCH Verlag GmbH & Co.

    This work addresses how human societies, and other diverse and distributed systems, solve collective challenges that are not approachable from the level of the individual, and how the Internet will change the way societies and organizations view problem solving. The authors apply the ideas developed in self-organizing systems to understand self-organization in informational systems. The simplest explanation as to why animals (for example, ants, wolves, and humans) are organized into societies is that these societies enhance the survival of the individuals which make up the populations. Individuals contribute to, as well as adapt to, these societies because they make life easier in one way or another, even though they may not always understand the process, either individually or collectively. Despite the lack of understanding of the how of the process, society during its existence as a species has changed significantly, from separate, small hunting tribes to a highly technological, globally integrated society. The authors combine this understanding of societal dynamics with self-organization on the Internet (the Net). The unique capability of the Net is that it combines, in a common medium, the entire human-technological system in both breadth and depth: breadth in the integration of heterogeneous systems of machines, information and people; and depth in the detailed capturing of the entire complexity of human use and creation of information. When the full diversity of societal dynamics is combined with the accuracy of communication on the Net, a phase transition is argued to occur in problem solving capability. Through conceptual examples, an experiment of collective decision making on the Net and a simulation showing the effect of noise and loss on collective decision making, the authors argue that the resulting symbiotic structure of humans and the Net will evolve as an alternative problem solving approach for groups, organizations and society.

    This cross-sectional study comprises a questionnaire-based survey regarding knowledge about human papillomavirus and its vaccine among students in different educational fields at public and private universities in the city of Lahore in Pakistan. A 26-item questionnaire was used to attain the objective of this study. The reliability of this tool was assessed using Cronbach's alpha (0.79) and the Kaiser-Meyer-Olkin value was 0.827. The response rate to the survey was 78.0%, of whom the majority (74.9%) were females and 308 (79%) were single (median age=23 years). While assessing the respondents' knowledge about HPV, 223(57%) students reported that they had already heard of HPV (human papillomavirus) and nearly 215 (55%) reported that HPV causes cervical cancer and can infect both men and women. Gender and field of study were two main factors found influencing the respondents' knowledge about HPV. Moreover, students' understanding about the mode of transmission of HPV was cursory: 40.51% said they did not know how HPV is transmitted, 133 (34.10%) stated that HPV spreads through the exchange of bodily fluids, and 22 (5.64%) selected cough/sneezing. In terms of prevention, 175 (44.87%) students stated that HPV can be prevented by vaccination, 30.0% reported sexual abstinence, 21.54% using condoms, and nearly 5.38% disclosed use of antibiotics. Addressing the knowledge of students regarding HPV vaccine, nearly 53% stated there is no vaccine against HPV and almost 64% rejected the statement that HPV vaccine prevents cervical cancer. In addition, students reported that they will be more than willing to get vaccinated for HPV if their physician recommend them (RII=0.74) followed by parents (RII=0.69). The results of this study revealed a poor understanding among respondents about the health problems associated with HPV, its prevention, modes of transmission and arability of HPV vaccine in Pakistan.

  1. Multi-Disciplinary Knowledge Synthesis for Human Health Assessment on Earth and in Space

    Science.gov (United States)

    Christakos, G.

    We discuss methodological developments in multi-disciplinary knowledge synthesis (KS) of human health assessment. A theoretical KS framework can provide the rational means for the assimilation of various information bases (general, site-specific etc.) that are relevant to the life system of interest. KS-based techniques produce a realistic representation of the system, provide a rigorous assessment of the uncertainty sources, and generate informative health state predictions across space-time. The underlying epistemic cognition methodology is based on teleologic criteria and stochastic logic principles. The mathematics of KS involves a powerful and versatile spatiotemporal random field model that accounts rigorously for the uncertainty features of the life system and imposes no restriction on the shape of the probability distributions or the form of the predictors. KS theory is instrumental in understanding natural heterogeneities, assessing crucial human exposure correlations and laws of physical change, and explaining toxicokinetic mechanisms and dependencies in a spatiotemporal life system domain. It is hoped that a better understanding of KS fundamentals would generate multi-disciplinary models that are useful for the maintenance of human health on Earth and in Space.

    Full Text Available The social and ecological systems of Mediterranean streams are intrinsically linked as a result of long human occupation. In this region, these links vary greatly across small distances due to geomorphology, resulting in great diversity across space, which poses particular challenges for understanding and managing these systems. This demands (i interdisciplinary integration of knowledge that focuses on the social-ecological interactions, while according due consideration to the whole; and also (ii transdisciplinary integration, integrating lay and expert knowledge to understand local specificities. To address these needs - a focus on interactions and local knowledge - the research presented here studies the human-nature relationship in Mediterranean streams. Its main objective is to improve understanding of Mediterranean streams, but it also provides practical inputs to enhance local-level management. The study adopts an applied approach from the perspective of natural resources management. A case study was developed conducting field work on streams within the Natura 2000 site of Monfurado, Portugal - a mainly privately owned area with conflicting land uses between conservation and farming. Rivers and streams in Portugal are considered to be in very bad condition, particularly with regard to water quality. The experimental design was based, from a critical realism perspective of inter- and trans-disciplinarity, on the complementarities between methodologies from (i the social sciences: value survey and analysis of discourse; and (ii the natural sciences: biomonitoring and integrity biotic indexes. Results characterized the connected systems from both ecological and social points of view. They also characterized the relationship between both dimensions. We concluded that well-established riparian vegetation cover of streams is a key structural element of the human-nature relationship in the Mediterranean streams of Monfurado at several levels

    INSPIRE is the new high-energy physics scientific information system developed by CERN, DESY, Fermilab and SLAC. INSPIRE combines the curated and trusted contents of SPIRES database with Invenio digital library technology. INSPIRE contains the entire HEP literature with about one million records and in addition to becoming the reference HEP scientific information platform, it aims to provide new kinds of data mining services and metrics to assess the impact of articles and authors. Grid and cloud computing provide new opportunities to offer better services in areas that require large CPU and storage resources including document Optical Character Recognition (OCR) processing, full-text indexing of articles and improved metrics. D4Science-II is a European project that develops and operates an e-Infrastructure supporting Virtual Research Environments (VREs). It develops an enabling technology (gCube) which implements a mechanism for facilitating the interoperation of its e-Infrastructure with other autonomously running data e-Infrastructures. As a result, this creates the core of an e-Infrastructure ecosystem. INSPIRE is one of the e-Infrastructures participating in D4Science-II project. In the context of the D4Science-II project, the INSPIRE e-Infrastructure makes available some of its resources and services to other members of the resulting ecosystem. Moreover, it benefits from the ecosystem via a dedicated Virtual Organization giving access to an array of resources ranging from computing and storage resources of grid infrastructures to data and services.

    In Kenya, human immunodeficiency virus (HIV) prevalence ranks among the highest in the world. Approximately 60 000 infections yearly are attributed to vertical transmission including the process of labour and breast-feeding. The vast of the population affected is in the developing world. Clinical officers and nurses play an important role in provision of primary health care to antenatal and postnatal mothers. There are a few studies that have explored the clinicians' knowledge on breast-feeding in the face of HIV and in relation to vertical transmission this being a vital component in prevention of maternal-to-child transmission. The aim of this study was to evaluate clinicians' knowledge on HIV in relation to breast-feeding in Kenya. A cross-sectional survey was conducted to assess knowledge of 161 clinical officers and nurses serving in the maternity and children' wards in various hospitals in Kenya. The participants were derived from all district and provincial referral facilities in Kenya. A preformatted questionnaire containing a series of questions on HIV and breast-feeding was administered to clinicians who were then scored and analyzed. All the 161 participants responded. Majority of clinicians (92%) were knowledgeable regarding prevention of mother-to-child transmission. Regarding HIV and breast-feeding, 49.7% thought expressed breast milk from HIV-positive mothers should be heated before being given. Majority (78.3%) thought breast milk should be given regardless of availability of alternatives. According to 74.5% of the participants, exclusive breast-feeding increased chances of HIV transmission. Two-thirds (66.5%) would recommend breast-feeding for mothers who do not know their HIV status (66.5%). This study observes that a majority of the clinicians have inadequate knowledge on breast-feeding in the face of HIV. There is need to promote training programmes on breast-feeding and transmission of HIV from mother to child. This can be done as in

    Led by the agency director, the agency engaged in a Strategic Review, based on a comprehensive assessment of agency performance that identified strategies to improve organizational effectiveness through increased data-informed practice and knowledge management. The Strategic Review gathered information on staff perceptions, perceptions of external stakeholders, changing citywide and neighborhood demographics, policy mandates, and budget and workload issues. The need for the review was based upon multiple, substantial changes not addressed in the 2000 Strategic Plan, including the 2004 merger of the Department of Human Services and the Department of Aging and Adult Services, changes among the executive management team, transitions among key political entities, new policy mandates and changing budget allocations. This case study describes the Strategic Review process and content, summarizing key challenges and lessons related to addressing workload demands, fostering positive staff attitudes, balancing internal and external information needs, and integrating data use and planning processes across the agency.

    Cervical cancer is a major health disparity among Asian Americans, with cervical cancer rates of Vietnamese women being significantly higher than for the general US female population and low screening rates reported for Asian American females. Focus groups and interviews were conducted with young Vietnamese, Filipino, and Korean adults (ages 18-29) to collect information on knowledge, perceptions and sources of information regarding cervical cancer, Pap tests and the human papillomavirus. 16 Korean, 18 Vietnamese, and 18 Filipino (50% female) adults participated in the study. Many participants had never heard of HPV, cervical cancer and Pap testing. Cervical cancer screening rates were low for Korean and Vietnamese females and were influenced by moral beliefs and lack of awareness. Culturally relevant education materials that consider specific Asian ethnicity and language are needed to increase awareness of cervical cancer, Pap testing, and HPV among Asian American young adults.

    Full Text Available Background: Human papilloma virus (HPV is regarded as the main cause in the etiology of cervical cancer. The purpose of our study is to assess the knowledge of medical students about HPV vaccine and to evaluate their opinion on this subject.   Material and Method: The study population consisted of 488 medical students. The survey was composed of questions intended   to obtain information about transmission route of HPV, types of HPV, role of HPV in cervical cancer, whether HPV is treatable or not, which types of HPV the HPV vaccine prevents, the age groups HPV vaccine is administered, the opinions on HPV vaccine and sufficiency of public health, whether female students have underwent vaccination and if not what their drawbacks are.   Results: Mean age of the students participating in the study was 21±4 and 58 % of the patients were female. Out of 448 medical students, 60% of them did not know that HPV was a sexually transmitted disease. Only 55% students knew about the association of HPV with cervical cancer and 52% participants stated that HPV vaccine could not be preventive against cervical cancer. None of female students had been immunized and 67% of female students did not consider getting immunized. Among those who did not consider getting immunized, 70% said they had worries about the safety of the vaccine. Conclusion: Our study results revealed that the knowledge of medical students about HPV is satisfactory, however their knowledge about HPV vaccine, immunization status and desire to be immunized were little.

    Background If women who receive the human papillomavirus (HPV) vaccine are unduly reassured about the cancer prevention benefits of vaccination, they may choose not to participate in screening, thereby increasing their risk for cervical cancer. This study assesses adult women’s knowledge of the need to continue cervical cancer screening after HPV vaccination, describes Pap test intentions of vaccinated young adult women, and evaluates whether knowledge and intentions differ across groups at greatest risk for cervical cancer. Methods Data were from the 2008 Health Information National Trends Survey (HINTS) and the 2008 National Health Interview Survey (NHIS), which initiated data collection approximately 18 months after the first FDA approval of an HPV vaccine. We calculated associations between independent variables and the outcomes using chi-square tests. Results Of 1,586 female HINTS respondents ages 18 through 74, 95.6% knew that HPV-vaccinated women should continue to receive Pap tests. This knowledge did not vary significantly by race/ethnicity, education, income, or healthcare access. Among 1,101 female NHIS respondents ages 18 to 26 who had ever received a Pap test, the proportion (12.7%; n = 139) who reported receipt of the HPV vaccine were more likely than those not vaccinated to plan to receive a Pap test within three years (98.1% vs. 92.5%, pknowledge and intention to participate in Pap testing after HPV vaccination. The vast majority of young adult women who received the HPV vaccine within its first two years on the market intend to participate in cervical cancer screening in the near future. Future studies are needed to examine whether those vaccinated in adolescence will become aware of, and adhere to, screening guidelines as they become eligible. PMID:21473953

    The rehabilitative dental care is important for maintaining adequate nutrition, guarding against wasting syndrome and malnutrition among human immunodeficiency virus (HIV)-infected individuals. The aim of this study is to determine the Nigerian dental technology students' knowledge and misconceptions about HIV infection and their willingness to care for HIV-infected patients. This descriptive cross-sectional study of dental technology students of Federal School of Dental Therapy and Technology Enugu, Nigeria was conducted in 2010. Data was subjected to descriptive, non-parametric and parametric statistics using the statistical package for the social sciences (SPSS) version 17.0 (Chicago Illinois, USA). P 4.0% (8/198) of the respondents erroneous described HIV as harmless, self-limitation and antibiotics responsive infection respectively. Of the respondents, 78.8% (156/198) and 83.3% (165/198) of them expressed willingness to care for HIV-infected patients and expressed need for training in the clinical care of HIV-infected patients respectively. Overall, the respondents opined that the dental therapists are the most suitable dental professional to pass HIV-related information to patients in the dental setting ahead of dentists and dental surgery assistants. The expressed willingness to care for HIV-infected patients, knowledge about the mode of HIV transmission and prevention among the respondents were high with existent misconceptions. There were no significant differences in the knowledge about HIV infection and willingness to care for HIV-infected patients among respondents in the lower class and those in upper class.

This study was performed on 259 nursing students in the Department of Nursing and 137 nurses working in Health Research and Practice Center, approved to participate in the study between April-June 2012. The study was performed universally without selecting a sample. A questionnaire that was prepared for evaluating participants' knowledge and attitudes about human papilloma virus (HPV) vaccine was distributed to the nurses and data obtained from the forms were transferred to SPSS 15.00 program and statistically analyzed. It was found that 54.8% of the student nurses were between 21-24 years old and 13.1% of working students were between 25-28 years old. When student nurses and working nurses were compared in terms of their knowledge about the causes of cervical cancer, their ideas about prevention from cervical cancer with HPV vaccine, their ideas about possible risks of HPV vaccine and conservation ratios of HPV vaccine, it was observed that there were no statistically significant differences (p>0.05). When student nurses and working nurses were compared in terms of the information-source about HPV, ways of HPV contamination, awareness about people who are susceptible to HPV contamination and age of HPV vaccination, it was determined that there was a statistically significant difference (pknowledge about cervical cancer and HPV vaccine, but this was not sufficient. Therefore; it is recommended to use verbal, written and visual communication tools intensively in order to have topics on cervical cancer, early diagnosis and prevention in bachelor and master programs for nurses, to inform society about cervical cancer and HPV vaccine for public health and to teach precautions for its prevention.

    Full Text Available The expression and regulation of genes in different tissues are fundamental questions to be answered in biology. Knowledge enrichment analysis for tissue specific (TS and housekeeping (HK genes may help identify their roles in biological process or diseases and gain new biological insights.In this paper, we performed the knowledge enrichment analysis for 17,343 genes in 84 human tissues using Gene Set Enrichment Analysis (GSEA and Hypergeometric Analysis (HA against three biological ontologies: Gene Ontology (GO, KEGG pathways and Disease Ontology (DO respectively.The analyses results demonstrated that the functions of most gene groups are consistent with their tissue origins. Meanwhile three interesting new associations for HK genes and the skeletal muscle tissuegenes are found. Firstly, Hypergeometric analysis against KEGG database for HK genes disclosed that three disease terms (Parkinson’s disease, Huntington’s disease, Alzheimer’s disease are intensively enriched.Secondly, Hypergeometric analysis against the KEGG database for Skeletal Muscle tissue genes shows that two cardiac diseases of “Hypertrophic cardiomyopathy (HCM” and “Arrhythmogenic right ventricular cardiomyopathy (ARVC” are heavily enriched, which are also considered as no relationship with skeletal functions.Thirdly, “Prostate cancer” is intensively enriched in Hypergeometric analysis against the disease ontology (DO for the Skeletal Muscle tissue genes, which is a much unexpected phenomenon.

    Cervical cancer is caused by oncogenic human papilloma virus (HPV) serotypes. Types 16 and 18 are responsible for approximately 75% of all cases in Europe. Low-malignant serotypes like HPV 6 and 11 are the cause of approximately 90% of all cases of conyloma accuminata. Approximately 75% of the adult population has or will become infected by one or more HPV serotypes. The purpose of the study was to investigate the level of knowledge of the cause of cervical cancer, cervical dysplasia and condylomas among women seen in Danish general practice, and to investigate the women's expectations to communication with regard to prophylactic initiatives and, finally, to determine which aspects would influence their wish for HPV-vaccination. Patient questionnaire in 26 general practices between September 2006 through February 2007. A total of 425 women aged 14-39 years were included in the study. Only 1.2% of the women correctly stated HPV as the cause of cervical cancer and 0.7% stated HPV as the cause of condylomas. In all, 96.2% thought that general practitioners should actively inform their patients of prophylactic initiatives such as vaccination against cervical cancer. Among all women, 96.4% considered HPV-vaccination. In this population, knowledge about the cause of cervical cancer and condylomas was limited. There was a clear wish - and expectation - to be actively informed on prophylactic initiatives by the general practitioner.

    Full Text Available The modern business world is characterized by dynamic, changing markets and continuous technological advance. This article focuses on an issue related to a definition of the meaning of a man and his location in an organization that works in conditions of globalization. Certainly, the meaning of human as the source of knowledge in the development of organization is not a new subject. Knowledge is intrinsically linked to people and enables them to act. Modern organizations base their theory on the knowledge they can exploit to improve the competence of the employee, his loyalty and commitment to the company which aims at the competitive predominance. The identification of knowledge is necessary for the effective implementation of knowledge management system. Above all, presented theoretical analysis pinpoints mainly on discussing a mans role and psychological contract in managing the knowledge.

    This work presents a biologically inspired method of gait generation. Bipedal gait pattern (for hip and knee joints) was taken into account giving the reference trajectories in a learning task. The four coupled oscillators were taught to generate the outputs similar to those in a human gait. After applying the correction functions the obtained generation method was validated using ZMP criterion. The formula suitable for real-time motion generation taking into account the positioning errors was also formulated. The small real robot prototype was tested to be able walk successfully following the elaborated motion pattern.

    Space Mining for resources such as water ice, and regolith, which contain many elements in the form of metals, minerals, volatiles and other compounds, is a necessary step in Space Resource Utilization. One of the primary goals is to extract propellants from the regolith such as oxygen and hydrogen which could then be used for in-space transportation. In addition, the space mining system can be used for various construction tasks that can benefit human and robotic exploration as well as scientific investigations based on the exposed topography. The National Aeronautics & Space Administration (NASA) Lunabotics Mining Competition is a university-level competition designed to engage and retain students in science, technology, engineering and mathematics (STEM). NASA will directly benefit from the competition by encouraging the development of innovative lunar excavation concepts from universities which may result in clever ideas and solutions which could be applied to an actual lunar excavation device or payload. The challenge is for students to design and build a remote controlled or autonomous excavator, called a lunabot, that can collect and deposit a minimum of 10 kilograms of lunar simulant within 15 minutes. The complexities of the challenge include the abrasive characteristics of the lunar simulant, the weight and size limitations of the lunabot, and the ability to control the lunabot from a remote control center or operate autonomously. This paper will present an update of the results and lessons learned during the first and second annual Lunabotics Mining Competitions held in May 2010 and May 2011. It will also preview the 2012 competition with a review of the revised rules. In 2010,22 United States (US) universities competed, and in May 2011 the competition was opened to international participation. In 2011, 36 teams actually competed from 26 USA states and 4 foreign countries (India, Bangladesh, Colombia and Canada). This combined total directly inspired an

    This review examines the role that respiratory plasticity has in the maintenance of breathing stability during sleep in individuals with sleep apnea. The initial portion of the review considers the manner in which repetitive breathing events may be initiated in individuals with sleep apnea. Thereafter, the role that two forms of respiratory plasticity, progressive augmentation of the hypoxic ventilatory response and long-term facilitation of upper airway and respiratory muscle activity, might have in modifying breathing events in humans is examined. In this context, present knowledge regarding the initiation of respiratory plasticity in humans during wakefulness and sleep is addressed. Also, published findings which reveal that exposure to intermittent hypoxia promotes breathing instability, at least in part, because of progressive augmentation of the hypoxic ventilatory response and the absence of long-term facilitation, are considered. Next, future directions are presented and are focused on the manner in which forms of plasticity that stabilize breathing might be promoted while diminishing destabilizing forms, concurrently. These future directions will consider the potential role of circadian rhythms in the promotion of respiratory plasticity and the role of respiratory plasticity in enhancing established treatments for sleep apnea.

  1. "The Human Condition" as social ontology: Hannah Arendt on society, action and knowledge.

    Science.gov (United States)

    Walsh, Philip

    2011-01-01

    Hannah Arendt is widely regarded as a political theorist who sought to rescue politics from "society," and political theory from the social sciences. This conventional view has had the effect of distracting attention from many of Arendt's most important insights concerning the constitution of "society" and the significance of the social sciences. In this article, I argue that Hannah Arendt's distinctions between labor, work, and action, as these are discussed in "The Human Condition" and elsewhere, are best understood as a set of claims about the fundamental structures of human societies. Understanding Arendt in this way introduces interesting parallels between Arendt's work and both classical and contemporary sociology. From this I draw a number of conclusions concerning Arendt's conception of "society," and extend these insights into two contemporary debates within contemporary theoretical sociology: the need for a differentiated ontology of the social world, and the changing role that novel forms of knowledge play in contemporary society as major sources of social change and order.

    Future electronics will take on more important roles in people's lives. They need to allow more intimate contact with human beings to enable advanced health monitoring, disease detection, medical therapies, and human-machine interfacing. However, current electronics are rigid, nondegradable and cannot self-repair, while the human body is soft, dynamic, stretchable, biodegradable, and self-healing. Therefore, it is critical to develop a new class of electronic materials that incorporate skinlike properties, including stretchability for conformable integration, minimal discomfort and suppressed invasive reactions; self-healing for long-term durability under harsh mechanical conditions; and biodegradability for reducing environmental impact and obviating the need for secondary device removal for medical implants. These demands have fueled the development of a new generation of electronic materials, primarily composed of polymers and polymer composites with both high electrical performance and skinlike properties, and consequently led to a new paradigm of electronics, termed "skin-inspired electronics". This Account covers recent important advances in skin-inspired electronics, from basic material developments to device components and proof-of-concept demonstrations for integrated bioelectronics applications. To date, stretchability has been the most prominent focus in this field. In contrast to strain-engineering approaches that extrinsically impart stretchability into inorganic electronics, intrinsically stretchable materials provide a direct route to achieve higher mechanical robustness, higher device density, and scalable fabrication. The key is the introduction of strain-dissipation mechanisms into the material design, which has been realized through molecular engineering (e.g., soft molecular segments, dynamic bonds) and physical engineering (e.g., nanoconfinement effect, geometric design). The material design concepts have led to the successful demonstrations of

    Cervical cancer is a major health problem and a leading cause of death among women in India. Of all the associated risk factors, high-risk human papillomavirus (HPV) infections being the principal aetiologic agent, two HPV vaccines are in use for the control of cervical cancer. The present study was undertaken to explore the knowledge, attitude and practice (KAP) on HPV vaccination among the healthcare providers in India. A cross-sectional study was conducted among 590 healthcare professionals from 232 hospitals and 80 PHCs of nine districts of Delhi-NCR (National Capital Region). A total of 590 (526 female, 64 male) healthcare providers were surveyed. Only 47 per cent of respondents recommended young women to get vaccinated against HPV. Majority of respondents (81%) were found to be aware about the existence of vaccines for cervical cancer prevention. District-wise, highest (88.3%) awareness about the existence of vaccines against HPV was reported from Gautam Budh Nagar and lowest (64%) in Faridabad. Although 86 per cent of gynaecologists were aware about the names of HPV vaccines available in the market, only 27 per cent of paramedical staff had this knowledge. There was a significant difference between the respondents from government and private sectors regarding their awareness about HPV vaccines. Lack of awareness about the principal cause, risk factors and symptoms for cervical cancer and HPV vaccination was significantly (P< 0.05) reported in the respondents from paramedical staff category. The findings reinforce continued medical education of healthcare providers, particularly those from the government sector on HPV vaccination for cervical cancer prevention. Public education is also pertinent for a successful HPV vaccination programme in the country.

    Kaiser Permanente implemented a new model of nursing communication at shift change-in the bedside nursing report known as the Nurse Knowledge Exchange (NKE) in 2004-but noted variations in its spread and sustainability across medical centers five years later. The six core elements of NKEplus were as follows: team rounding in the last hour before shift changes, pre-shift patient assignments that limit the number of departing nurses at shift change, unit support for uninterrupted bedside reporting, standardization for report and safety check formats, and collaboration with patients to update in-room care boards. In January 2011 Kaiser Permanente Southern California (KPSC; Pasadena) began implementing NKEplus in 125 nursing units across 14 hospitals, with the use of human-centered design principles: creating shared understanding of the need for change, minimum specifications, and customization by frontline staff. Champion teams on each nursing unit designed and pilot tested unit-specific versions of NKEplus for four to eight weeks. Implementation occurred in waves and proceeded from medical/surgical units to specialty units. Traditional performance improvement strategies of accountability, measurement, and management were also applied. By the end of 2012, 100% of the 64 medical/surgical units and 47 (77.0%) of the 61 specialty units in KPSC medical centers implemented NKEplus-as had all but 1 of the specialty units by May 2013. The mean KPSC score on the NKEplus nursing behavior bundle improved from 65.9% in 2010 to 71.3% in the first quarter of 2014. The mean KPSC Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) score for nurse communication improved from 73.1% in 2010 to 76.4% in the first quarter of 2014 (p < . 001). Human-centered implementation appeared to help spread a new model of nursing handoffs and change the culture of professional nursing practice related to shift change.

    Cervical cancer remains a major reproductive health problem among women especially in developing countries where about 190,000 women die from this disease annually. Despite efforts to reduce the burden of this disease, most attempts in low-resourced countries have not been successful partly from lack of awareness by women of this common cancer, as well as the role the human papilloma virus (HPV) plays in its aetiology and pathogenesis. To determine knowledge, attitudes and practice of women in Trinidad (a developing country) on HPV, cervical cancer and the HPV vaccine, we conducted a cross-sectional survey among 426 women in the reproductive age. A majority (58.4%) of participants had attained secondary level education. Whereas 326 (76.5%) women knew of cervical cancer, only 108 (25.4%) were aware of HPV and 68 (15.9%) knew of the association between HPV and cervical cancer. This study highlights the limited awareness of Trinidadian women with respect to HPV and its implication in cervical cancer aetiology. If the scourge of cervical cancer is to be adequately addressed, especially in low-resourced countries, then mass educational programmes on HPV, cervical cancer prevention, including screening and early detection and treatment of pre-cancerous lesions of the cervix, must be given high priority.

    Ever since man started to study systematically medicine for the first time he recognized the value of the knowledge of Anatomy in order to safely cut and treat the human body. However, over the centuries it has been proved that Anatomy is more than just a scientific field of medicine. The fact that Anatomy requires the use of human cadavers as an object to study brought to the surface many moral issues, which adumbrated its turbulent past. Additionally, Anatomy and its inextricable element, illustration, has many times been a source of inspiration for both the anatomists and the artists. This paper aims on the one hand to provide a condensed overview of the history of Anatomy and on the other hand to investigate the way Anatomy penetrates Art and, conversely, Art penetrates Anatomy.

    The aim of our study was to evaluate the level of knowledge of the adolescent girls who presented to our clinic about human papilloma virus (HPV) infection and HPV vaccine. Five hundred and one adolescent girls aged between 13 and 18 years who presented to the gynecology outpatient clinic between March 2012 and March 2013 were asked to answer the questions of the questionnaire about HPV and HPV vaccine. The "Participant Information Form" and "HPV Information Assessment Form" were used by examination of the related literature by the investigators. The data obtained were entered into the computer using the SPSS 16.5 program and evaluated. Descriptive statistics were shown with mean, standard deviation, number and percentage values. The mean age of 501 subjects who were included into the study was 15.92 years. 390 subjects (77.8%) who were included in the study had no information about HPV. 111 subjects (22.2%) stated that they heard of HPV before or had information about HPV. The mean age of the subjects who had information about human papilloma virus was found to be 16.52 years. The mean age of 390 subjects (77.8%) who had no information about human papilloma virus was 15.75 years. It was found that only one of the subjects (0.9%) was vaccinated with HPV vaccine. When the subjects who did not wish to be vaccinated were asked for the reason, 40.9% stated that the reason was inadequate information, 26.4% stated that the reason was high cost, 16.4% stated that the reason was the fact that they did not consider themselves at risk and 16.4% stated that the reason was the fact that they were afraid of side effects. In our study, it was found that the adolescent girls who constituted our study group had insufficient information about HPV and HPV vaccine. Verbal, written and visual communication tools and internet should be used intensively and efficiently for the objective of introducing HPV vaccine and teaching the precautions related with prevention of cervix cancer in

    Directory of Open Access Journals (Sweden)

    Zdzislaw Wasik

    2017-01-01

    Full Text Available This article aims at a confrontation of two approaches to epistemology in order to answer the question posed in its title whether the theory of knowledge should focus on static or dynamic aspects of human cognition. In the first part, the author presents a metascientific understanding of epistemology defined in his own works as an ordered set of investigative perspectives, which practicing researchers have at their disposal when they are interested to attain a specific state of knowledge, or to support their beliefs about the nature of investigative domains with regard to the existence forms and accessibility of investigated objects. And, in the second, the subject matter of a more detailed presentation constitutes a psychophysiological approach to epistemology pertaining to the human organism preoccupied with sensorial and mental activities as a cognizing subject who aims at achieving a certain kind of information about reality. Common for both approaches to epistemology is the attainment of experiential knowledge. However, when the metascientific epistemology refers to a dispositional-perspectivistic state of knowledge acquired in cognition, the attention of the psychophysiological epistemology is paid to cognitive-constructivists activities of human organisms as subject acquiring their knowledge through personal experiences.

    Purpose: Aims in this study are to (1) develop a computational model observer which reliably tracks the detectability of human observers in low dose computed tomography (CT) images reconstructed with knowledge-based iterative reconstruction (IMR™, Philips Healthcare) and filtered back projection (FBP) across a range of independent variables, (2) use the model to evaluate detectability trends across reconstructions and make predictions of human observer detectability, and (3) perform human observer studies based on model predictions to demonstrate applications of the model in CT imaging. Methods: Detectability (d′) was evaluated in phantom studies across a range of conditions. Images were generated using a numerical CT simulator. Trained observers performed 4-alternative forced choice (4-AFC) experiments across dose (1.3, 2.7, 4.0 mGy), pin size (4, 6, 8 mm), contrast (0.3%, 0.5%, 1.0%), and reconstruction (FBP, IMR), at fixed display window. A five-channel Laguerre–Gauss channelized Hotelling observer (CHO) was developed with internal noise added to the decision variable and/or to channel outputs, creating six different internal noise models. Semianalytic internal noise computation was tested against Monte Carlo and used to accelerate internal noise parameter optimization. Model parameters were estimated from all experiments at once using maximum likelihood on the probability correct, P{sub C}. Akaike information criterion (AIC) was used to compare models of different orders. The best model was selected according to AIC and used to predict detectability in blended FBP-IMR images, analyze trends in IMR detectability improvements, and predict dose savings with IMR. Predicted dose savings were compared against 4-AFC study results using physical CT phantom images. Results: Detection in IMR was greater than FBP in all tested conditions. The CHO with internal noise proportional to channel output standard deviations, Model-k4, showed the best trade-off between fit

  5. A bio-inspired memory model for structural health monitoring

    Science.gov (United States)

    Zheng, Wei; Zhu, Yong

    2009-04-01

    Long-term structural health monitoring (SHM) systems need intelligent management of the monitoring data. By analogy with the way the human brain processes memories, we present a bio-inspired memory model (BIMM) that does not require prior knowledge of the structure parameters. The model contains three time-domain areas: a sensory memory area, a short-term memory area and a long-term memory area. First, the initial parameters of the structural state are specified to establish safety criteria. Then the large amount of monitoring data that falls within the safety limits is filtered while the data outside the safety limits are captured instantly in the sensory memory area. Second, disturbance signals are distinguished from danger signals in the short-term memory area. Finally, the stable data of the structural balance state are preserved in the long-term memory area. A strategy for priority scheduling via fuzzy c-means for the proposed model is then introduced. An experiment on bridge tower deformation demonstrates that the proposed model can be applied for real-time acquisition, limited-space storage and intelligent mining of the monitoring data in a long-term SHM system.

Understanding the neural mechanism of this behavior can help neuroscientists to unravel the principles of information processing in complex neural systems (e.g. the human brain) and to create efficient and robust robotic systems. In this work, we have developed a biologically-inspired spiking neural network which is able to execute both first and second order conditioning. Experimental studies demonstrated that volume signaling (e.g. by the gaseous transmitter nitric oxide) contributes to memory formation in vertebrates and invertebrates including insects. Based on the existing knowledge of odor encoding in Drosophila, the role of retrograde signaling in memory function, and the integration of synaptic and non-synaptic neural signaling, a neural system is implemented as Simulated fly. Simulated fly navigates in a two-dimensional environment in which it receives odors and electric shocks as sensory stimuli. The model suggests some experimental research on retrograde signaling to investigate neural mechanisms of conditioning in insects and other animals. Moreover, it illustrates a simple strategy to implement higher cognitive capabilities in machines including robots. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Long-term structural health monitoring (SHM) systems need intelligent management of the monitoring data. By analogy with the way the human brain processes memories, we present a bio-inspired memory model (BIMM) that does not require prior knowledge of the structure parameters. The model contains three time-domain areas: a sensory memory area, a short-term memory area and a long-term memory area. First, the initial parameters of the structural state are specified to establish safety criteria. Then the large amount of monitoring data that falls within the safety limits is filtered while the data outside the safety limits are captured instantly in the sensory memory area. Second, disturbance signals are distinguished from danger signals in the short-term memory area. Finally, the stable data of the structural balance state are preserved in the long-term memory area. A strategy for priority scheduling via fuzzy c-means for the proposed model is then introduced. An experiment on bridge tower deformation demonstrates that the proposed model can be applied for real-time acquisition, limited-space storage and intelligent mining of the monitoring data in a long-term SHM system

    An Information Architecture facilitates the understanding and, hence, harnessing of the human system risk-related data supply chain which enhances the ability to securely collect, integrate, and share data assets that improve human system research and operations. By mapping the risk-related data flow from raw data to useable information and knowledge (think of it as a data supply chain), the Human Research Program (HRP) and Space Life Science Directorate (SLSD) are building an information architecture plan to leverage their existing, and often shared, IT infrastructure.

    1996-01-01

    The traditional gross anatomy laboratory experience, with modifications in evaluations that we outline later, meets the criteria of contextual-learning theory, expands the repertoire of core objectives we identify for our students, and may increase the likelihood of cognitive permanence of anatomical data. Our subjects included approximately 54 first-year medical students from each of three sequential class years (1996, 1997, 1998). As an alternative to more typical written and practical exams, examinations in a major portion of our gross anatomy program consist of two approximately 30 minute oral expositions by each student to his or her peers and a faculty member. Students demonstrate specific detail on cadaver, x-ray, cross sections, or a model. Clinical applications, spatial relationships, nomenclature, and functions are strongly emphasized. The results of this teaching approach to the utilization of anatomical knowledge in clinical situations requires further assessment: however, new attributes have been afforded our students with implementation of the present program: First, students learn anatomical detail equally well as the students of the more traditional system (based on board exam results). Second, students who completed the program indicate that this approach provides a useful simulation of what is expected later in their training. Third, students gradually gain confidence in verbal presentation, they demonstrate cognitive synthesis of separate conceptual issues, they retain information, and they are quite visibly more enthusiastic about anatomy and its importance in medicine. Our program demonstrates that the learning of applicable human anatomy is facilitated in a contextual-learning environment. Moreover, by learning anatomy in this way, other equally beneficial attributes are afforded the medical student, including, but not limited to, increases in communication skills, confidence in verbal presentation, synthesis of anatomical concepts

    The social sciences have become increasingly important in understanding natural resource management contexts and audiences, and are essential in design and delivery of effective and durable management strategies. Yet many agencies and organizations do not have the necessary resource management. We draw on the textbook definition of HD: how and why people value natural resources, what benefits people seek and derive from those resources, and how people affect and are affected by those resources and their management (Decker, Brown, and Seimer 2001). Clearly articulating how HD information can be used and integrated into natural resource management planning and decision-making is an important challenge faced by the HD field. To address this challenge, we formed a collaborative team to explore the issue of HD capacity-building for natural resource organizations and to advance the HD field. We define HD capacity as activities, efforts, and resources that enhance the ability of HD researchers and practitioners and natural managers and decision-makers to understand and address the social aspects of conservation.Specifically, we sought to examine current barriers to integration of HD into natural resource management, knowledge needed to improve HD capacity, and existing HD tools, resources, and training opportunities. We conducted a needs assessment of HD experts and practitioners, developed a framework for considering HD activities that can contribute both directly and indirectly throughout any phase of an adaptive management cycle, and held a workshop to review preliminary findings and gather additional input through breakout group discussions. This paper provides highlights from our collaborative initiative to help frame and inform future HD capacity-building efforts and natural resource organizations and also provides a list of existing human dimensions tools and resources.

    Full Text Available Classification rule set is important for Land Cover classification, which refers to features and decision rules. The selection of features and decision are based on an iterative trial-and-error approach that is often utilized in GEOBIA, however, it is time-consuming and has a poor versatility. This study has put forward a rule set building method for Land cover classification based on human knowledge and machine learning. The use of machine learning is to build rule sets effectively which will overcome the iterative trial-and-error approach. The use of human knowledge is to solve the shortcomings of existing machine learning method on insufficient usage of prior knowledge, and improve the versatility of rule sets. A two-step workflow has been introduced, firstly, an initial rule is built based on Random Forest and CART decision tree. Secondly, the initial rule is analyzed and validated based on human knowledge, where we use statistical confidence interval to determine its threshold. The test site is located in Potsdam City. We utilised the TOP, DSM and ground truth data. The results show that the method could determine rule set for Land Cover classification semi-automatically, and there are static features for different land cover classes.

  14. Integrating Ethno-Ecological and Scientific Knowledge of Termites for Sustainable Termite Management and Human Welfare in Africa

    Full Text Available Despite their well-known role as pests, termites also provide essential ecosystem services. In this paper, we undertook a comprehensive review of studies on human-termite interactions and farmers' indigenous knowledge across Sub-Saharan Africa in an effort to build coherent principles for termite management. The review revealed that local communities have comprehensive indigenous knowledge of termite ecology and taxonomy, and apply various indigenous control practices. Many communities also have elaborate knowledge of the nutritional and medicinal value of termites and mushrooms associated with termite nests. Children and women also widely consume termite mound soil for nutritional or other benefits encouraged by indigenous belief systems. In addition, subsistence farmers use termites as indicators of soil fertility, and use termite mound soil in low-risk farming strategies for crop production. In the past, chemical control of termites has been initiated without empirical data on the termite species, their damage threshold, and the social, ecological, or economic risks and trade-offs of the control. This review has provided new insights into the intimate nature of human-termite interactions in Africa and the risks of chemical control of termites to human welfare and the environment. We recommend that management of termites in future should be built on farmers' indigenous knowledge and adequate understanding of the ecology of the local termite species.

    2015-07-01

    It is known that active exploration of a new environment leads to better spatial learning than does passive visual exposure. We ask whether specific components of active learning differentially contribute to particular forms of spatial knowledge-the exploration-specific learning hypothesis. Previously, we found that idiothetic information during walking is the primary active contributor to metric survey knowledge (Chrastil & Warren, 2013). In this study, we test the contributions of 3 components to topological graph and route knowledge: visual information, idiothetic information, and cognitive decision making. Four groups of participants learned the locations of 8 objects in a virtual hedge maze by (a) walking or (b) watching a video, crossed with (1) either making decisions about their path or (2) being guided through the maze. Route and graph knowledge were assessed by walking in the maze corridors from a starting object to the remembered location of a test object, with frequent detours. Decision making during exploration significantly contributed to subsequent route finding in the walking condition, whereas idiothetic information did not. Participants took novel routes and the metrically shortest routes on the majority of both direct and barrier trials, indicating that labeled graph knowledge-not merely route knowledge-was acquired. We conclude that, consistent with the exploration-specific learning hypothesis, decision making is the primary component of active learning for the acquisition of topological graph knowledge, whereas idiothetic information is the primary component for metric survey knowledge.

    2017-03-01

    Human flesh search as a new net crowed behavior, on the one hand can help us to find some special information, on the other hand may lead to privacy leaking and offending human right. In order to study the mechanism of human flesh search, this paper proposes a simulation model based on agent-based model and complex networks. The computational experiments show some useful results. Discovered information quantity and involved personal ratio are highly correlated, and most of net citizens will take part in the human flesh search or will not take part in the human flesh search. Knowledge quantity does not influence involved personal ratio, but influences whether HFS can find out the target human. When the knowledge concentrates on hub nodes, the discovered information quantity is either perfect or almost zero. Emotion of net citizens influences both discovered information quantity and involved personal ratio. Concretely, when net citizens are calm to face the search topic, it will be hardly to find out the target; But when net citizens are agitated, the target will be found out easily.

    Full Text Available The purpose of the study was to investigate the influence of human papillomavirus (HPV vaccination on adolescent girls' knowledge of HPV and HPV vaccine, perception of sexual risk and intentions for sexual debut. This cross-sectional comparative study was conducted in Ibanda and Mbarara districts. Data was collected using a standardized self-administered questionnaire and analyzed using the Statistical Package for the Social Sciences computer software. Univariate, bivariate, and logistic regression analyses were conducted with significance level set at p < .05. Results showed that HPV vaccination was associated with being knowledgeable (Crude OR: 5.26, CI: 2.32-11.93; p = 0.000. Vaccination against HPV did not predict perception of sexual risk. Knowledge was low (only 87/385 or 22.6% of vaccinated girls were knowledgeable, but predicted perception of a high sexual risk (Adjusted OR: 3.12, CI: 1.37-3.63; p = 0.008. HPV vaccination, knowledge and perceived sexual risk did not predict sexual behaviour intentions. High parental communication was associated with adolescent attitudes that support postponement of sexual debut in both bivariate and multiple regression analyses. In conclusion, findings of this study suggest that HPV vaccination is not likely to encourage adolescent sexual activity. Influence of knowledge on sexual behaviour intentions was not definitively explained. Prospective cohort studies were proposed to address the emerging questions.

    To assess the level of knowledge regarding cervical cancer and the acceptance of the human papilloma virus (HPV) vaccine among Saudi female students in health colleges. This cross-sectional study of a convenient sample encompassed 1400 students in Health Colleges at Princess Nora Bint Abdul Rahman University, Riyadh, Saudi Arabia was conducted between December 2013 and February 2014. A self-administrated questionnaire was distributed to all participants. Data collected included socio-demographic data, knowledge of cervical cancer risk factors and clinical presentation, Pap smear, and HPV vaccine acceptance. The questionnaire reliability as tested by Cronbach's alpha was 0.82. The response rate was 89.9%, and data analysis revealed that 95.7% of students had poor knowledge level. The Pap smear was poorly recognized as a screening tool, with 46.7% of students having heard of the test. Senior and medical students had a significantly higher knowledge score. Father's health profession, high monthly income, and presence of cervical cancer among family members or friends increased the level of knowledge. Vaccine acceptance is influenced by its price, approximately 80% of students thought that an affordable vaccine price should not exceed 300 Saudi Riyals. Perceived barriers to the vaccine were fear of injections and vaccine side effects. There is a lack of knowledge and misinformation regarding cervical cancer, Pap smear, and HPV as a major risk factor for cancer of the cervix. These data can be used as a benchmark to formulate effective awareness programs.

    Full Text Available Abstract Emotion recognition has become a fundamental task in human-computer interaction systems. In this article, we propose an emotion recognition approach based on biologically inspired methods. Specifically, emotion classification is performed using a long short-term memory (LSTM recurrent neural network which is able to recognize long-range dependencies between successive temporal patterns. We propose to represent data using features derived from two different models: mel-frequency cepstral coefficients (MFCC and the Lyon cochlear model. In the experimental phase, results obtained from the LSTM network and the two different feature sets are compared, showing that features derived from the Lyon cochlear model give better recognition results in comparison with those obtained with the traditional MFCC representation.

    2017-01-01

    The purpose of this study was to examine human papillomavirus (HPV) and HPV vaccine knowledge, attitudes, and uptake in college students and to identify factors associated with vaccination status utilizing the Precaution Adoption Process Model (PAPM). The sample included 383 undergraduates from a public university who participated in February and March 2015. Students were emailed an anonymous online survey assessing knowledge, attitudes, and perceptions related to HPV and HPV vaccination, as well as their stage in the PAPM regarding vaccination completion. Significantly more females (47.3%) than males (15.8%) were vaccinated. While most students had basic knowledge of HPV, they had low perceptions of their susceptibility to contract HPV. Most unvaccinated students were in the early stages of decision-making related to vaccination. Campus health centers have an opportunity to increase HPV vaccination rates. This study indicates that students need prompts from providers, as well as education regarding susceptibility to HPV. PMID:28786994

    Because human papillomavirus (HPV) vaccine rates remain low, we evaluated US school nurses' knowledge, attitudes, perceptions of their role as opinion leaders, and professional practice regarding HPV vaccine, and assessed whether knowledge, attitudes, and perceptions of being an opinion leader influenced their professional practice regarding the HPV vaccine. We used a cross-sectional design by recruiting members from the National Association of School Nurses. All participants (N = 505) were e-mailed a survey designed for this study. Structural equation modeling (SEM) tested direct and indirect effects. Overall, school nurses had knowledge about HPV and the vaccine, and positive attitudes toward the vaccine. They had less-than-enthusiastic perceptions of their role as opinion leaders regarding the vaccine and implemented few activities related to providing vaccine information. The model revealed a good fit (χ(2)=20.238 [df=8, prole as opinion leaders. © 2015, American School Health Association.

    Human musculoskeletal system resources of the human body are valuable for the learning and medical purposes. Internet-based information from conventional search engines such as Google or Yahoo cannot response to the need of useful, accurate, reliable and good-quality human musculoskeletal resources related to medical processes, pathological knowledge and practical expertise. In this present work, an advanced knowledge-based personalized search engine was developed. Our search engine was based on a client-server multi-layer multi-agent architecture and the principle of semantic web services to acquire dynamically accurate and reliable HMSR information by a semantic processing and visualization approach. A security-enhanced mechanism was applied to protect the medical information. A multi-agent crawler was implemented to develop a content-based database of HMSR information. A new semantic-based PageRank score with related mathematical formulas were also defined and implemented. As the results, semantic web service descriptions were presented in OWL, WSDL and OWL-S formats. Operational scenarios with related web-based interfaces for personal computers and mobile devices were presented and analyzed. Functional comparison between our knowledge-based search engine, a conventional search engine and a semantic search engine showed the originality and the robustness of our knowledge-based personalized search engine. In fact, our knowledge-based personalized search engine allows different users such as orthopedic patient and experts or healthcare system managers or medical students to access remotely into useful, accurate, reliable and good-quality HMSR information for their learning and medical purposes.

    Industry is being challenged by the departure of experienced managers and workers. The loss of skills and the difficulty of finding qualified replacements can negatively affect operations, environment, safety and economics. There is a need to capture, preserve and pass along both documented and undocumented knowledge before aging workers depart the workplace. How to do it? Our ancestors faced the same problem, and they often solved it in a personal way through a Master-Journeyman-Apprentice system. Our modern education system is an extension of that system, augmented by extensive use of textbooks. This system now is stretched to its limits by two factors, (a) the need to update the teacher's knowledge, and (b) the need to update high quality textbooks. Modem Masters are so busy doing their work that they have no time to pass knowledge on in an effective manner. When they retire, their knowledge often is lost. The CANTEACH project was initiated to fill this gap. The essence of this knowledge capture process is acquisition of archival documents that are relevant to current practice in the field-in our case, CANDU power plant engineering. This project is made possible by voluntary contributions from Masters in the field; it can proceed only by avoiding the pitfalls of excessive security and intellectual property rules. This paper describes the mechanisms used to make this archival knowledge openly available for operators, designers, educators, and students of this technology. (author)

    Cervical cancer is a major health problem globally, especially in sub-Saharan Africa, Nigeria inclusive. One of the preventive measures is the vaccination of teenagers against oncogenic human papilloma virus. The aim of this study was to find out the level of knowledge mothers possess about these vaccines and their willingness to administer vaccination to their teenage girls. This was a cross-sectional descriptive study of 255 consecutive women attending antenatal clinic at the University of Abuja Teaching Hospital, Abuja. They were given either a self-administered questionnaire or interviewer-administered questionnaire containing both closed and open-ended questions. Information recorded includes socio-demographic variables, knowledge of cervical cancer, knowledge of HPV/HPV vaccines and acceptance of these vaccines for their adolescent girls. The data was analysed using descriptive statistics. The mean age of the respondents was 26.9 years. Over 90% had at least secondary education. A total of 102 (40%) had the knowledge of cancer of the cervix while 153 (60%) had never heard about it. Overall, 236 (92.5%) of them had no idea about the predisposing factors. The study showed that only 23 (9.0%) out of the total respondents had heard about human papilloma virus (HPV) infection. In the same vein, 20 (7.8%) had knowledge about HPV vaccine. Among the respondents, who had the knowledge of HPV and vaccination, 18.2% and 23.4% of them had secondary and tertiary levels of education respectively. Overall, 160 (62.8%) accepted that the vaccines could be administered to their teenage girls. Awareness of cervical cancer, HPV infections, and HPV vaccines is low among antenatal clinic attendees in Gwagwalada, Abuja. However, majority of them would want their girls vaccinated against HPV infections. There is a need for all stakeholders to step up awareness creation for improved HPV vaccination project in Nigeria.

    There are two considerations for optical biomimetics: the diversity of submicrometre architectures found in the natural world, and the industrial manufacture of these. A review exists on the latter subject, where current engineering methods are considered along with those of the natural cells. Here, on the other hand, I will provide a modern review of the different categories of reflectors and antireflectors found in animals, including their optical characterization. The purpose of this is to inspire designers within the $2 billion annual optics industry.

  19. Demonstration Integrated Knowledge-Based System for Estimating Human Error Probabilities

    Energy Technology Data Exchange (ETDEWEB)

    Auflick, Jack L.

    1999-04-21

    Human Reliability Analysis (HRA) is currently comprised of at least 40 different methods that are used to analyze, predict, and evaluate human performance in probabilistic terms. Systematic HRAs allow analysts to examine human-machine relationships, identify error-likely situations, and provide estimates of relative frequencies for human errors on critical tasks, highlighting the most beneficial areas for system improvements. Unfortunately, each of HRA's methods has a different philosophical approach, thereby producing estimates of human error probabilities (HEPs) that area better or worse match to the error likely situation of interest. Poor selection of methodology, or the improper application of techniques can produce invalid HEP estimates, where that erroneous estimation of potential human failure could have potentially severe consequences in terms of the estimated occurrence of injury, death, and/or property damage.

    To compare the basic knowledge scores, attitudes and acceptability to HPV immunization before and after acknowledge about HPV, cervical cancer and vaccine to study group. An anonymous survey was applied to women attending the outpatient clinic, Thammasat University Hospital from April 2010 to October 2010. Basic knowledge about cervical cancer, HPV, HPV vaccine, attitudes and acceptability to HPV immunization were collected via a self administered questionnaire. A total of 173 mothers completed the survey responses rate of 86.5% (173/200). There is no difference in characteristic and lifestyles of the responders. The basic knowledge scores was higher in the subjects who had higher education level and regular cervical screening history. Most of subjects (> 85%) recognized that HPV is associated with cervical cancer but more than half of them confused about route of transmission. Basic knowledge scores is increased in all acceptability group (strongly agree to strongly disagree) after be informed about HPV and vaccine was observed. Most subjects (78.6%) agree to their daughters' vaccination indicating the high vaccine acceptances. The leading factors to maternal acceptances were free vaccination, negative attitudes such as sexual behavior of daughters and positive attitudes such as vaccine efficacy. HPV vaccine acceptance seems to be depended on cost and efficacy than maternal knowledge. The vaccine is not widely used. The cost-effectiveness analysis should be provided by government. Education and communication in public media are aimed for increasing coverage of vaccination in the future. Maternal acceptances of vaccine depend on high efficacy and low cost.

    2013-09-01

    It seems intuitively obvious that active exploration of a new environment would lead to better spatial learning than would passive visual exposure. It is unclear, however, which components of active learning contribute to spatial knowledge, and previous literature is decidedly mixed. This experiment tests the contributions of 4 components to metric survey knowledge: visual, vestibular, and podokinetic information and cognitive decision making. In the learning phase, 6 groups of participants learned the locations of 8 objects in a virtual hedge maze by (a) walking, (b) being pushed in a wheelchair, or (c) watching a video, crossed with (1) making decisions about their path or (2) being guided through the maze. In the test phase, survey knowledge was assessed by having participants walk a novel shortcut from a starting object to the remembered location of a test object, with the maze removed. Performance was slightly better than chance in the passive video condition. The addition of vestibular information did not improve performance in the wheelchair condition, but the addition of podokinetic information significantly improved angular accuracy in the walking condition. In contrast, there was no effect of decision making in any condition. The results indicate that visual and podokinetic information significantly contribute to survey knowledge, whereas vestibular information and decision making do not. We conclude that podokinetic information is the primary component of active learning for the acquisition of metric survey knowledge. PsycINFO Database Record (c) 2013 APA, all rights reserved.

    In the field of stem cell biology and diabetes, we and others seek to derive mature and functional human pancreatic β cells for disease modeling and cell replacement therapy. Traditionally, knowledge gathered from rodents is extended to human pancreas developmental biology research involving human pluripotent stem cells (hPSCs). While much has been learnt from rodent pancreas biology in the early steps toward Pdx1(+) pancreatic progenitors, much less is known about the transition toward Ngn3(+) pancreatic endocrine progenitors. Essentially, the later steps of pancreatic β cell development and maturation remain elusive to date. As a result, the most recent advances in the stem cell and diabetes field have relied upon combinatorial testing of numerous growth factors and chemical compounds in an arbitrary trial-and-error fashion to derive mature and functional human pancreatic β cells from hPSCs. Although this hit-or-miss approach appears to have made some headway in maturing human pancreatic β cells in vitro, its underlying biology is vaguely understood. Therefore, in this mini-review, we discuss some of these late-stage signaling pathways that are involved in human pancreatic β cell differentiation and highlight our current understanding of their relevance in rodent pancreas biology. Our efforts here unravel several novel signaling pathways that can be further studied to shed light on unexplored aspects of rodent pancreas biology. New investigations into these signaling pathways are expected to advance our knowledge in human pancreas developmental biology and to aid in the translation of stem cell biology in the context of diabetes treatments.

    Again an again real incidents and accidents show that human factors may seriously affect the safety of plants. This is also true for, e.g. nuclear facilities. The major methods which are used to quantify the reliability of humans are described. These methods are applied in the framework of German and international risk analyses. Since in probabilistic safety analyses data bases are of great importance of the, however, naturally very difficult quantitative evaluation of human errors, the study also discusses the present limits to the treatment of human misbehavior in safety analyses.

    Research and treatment in the nervous system is challenged by many physiological barriers posing a major hurdle for neurologists. The CNS is protected by a formidable blood brain barrier (BBB) which limits surgical, therapeutic and diagnostic interventions. The hostile environment created by reactive astrocytes in the CNS along with the limited regeneration capacity of the PNS makes functional recovery after tissue damage difficult and inefficient. Nanomaterials have the unique ability to interface with neural tissue in the nano-scale and are capable of influencing the function of a single neuron. The ability of nanoparticles to transcend the BBB through surface modifications has been exploited in various neuro-imaging techniques and for targeted drug delivery. The tunable topography of nanofibers provides accurate spatio-temporal guidance to regenerating axons. This review is an attempt to comprehend the progress in understanding the obstacles posed by the complex physiology of the nervous system and the innovations in design and fabrication of advanced nanomaterials drawing inspiration from natural phenomenon. We also discuss the development of nanomaterials for use in Neuro-diagnostics, Neuro-therapy and the fabrication of advanced nano-devices for use in opto-electronic and ultrasensitive electrophysiological applications. The energy efficient and parallel computing ability of the human brain has inspired the design of advanced nanotechnology based computational systems. However, extensive use of nanomaterials in neuroscience also raises serious toxicity issues as well as ethical concerns regarding nano implants in the brain. In conclusion we summarize these challenges and provide an insight into the huge potential of nanotechnology platforms in neuroscience. Copyright © 2016 Elsevier Ltd. All rights reserved.

    A cross-sectional study was conducted among 300 Malaysian women in the obstetrics and gynecology outpatient clinic in a selected hospital in Bangi, Selangor to determine the level of knowledge of HPV and HPV vaccines, attitudes toward HPV vaccination and barriers of being vaccinated. Factors associated with knowledge and attitudes were also addressed with a questionnaire. Seventy eight women (26%) had heard about the HPV virus and 65 about HPV vaccines (21.7%). Marital status was associated significantly with awareness of HPV and HPV vaccine (p=0.002, p=0.002; respectively), in addition to level of education (p=0.042). The percentages of women who reported correct answers for the questions on knowledge of HPV and HPV vaccine ranged from 12% to 25%. One hundred fifty nine respondents (53%) had a positive attitude toward HPV vaccination. Age, marital status, and level of education were associated significantly with attitude (plevel of knowledge of HPV and HPV vaccine. Education of population is highly recommended and barriers to being vaccinated should be dealt with seriously.

    Objectives: To assess the level of knowledge regarding cervical cancer and the acceptance of the human papilloma virus (HPV) vaccine among Saudi female students in health colleges. Methods: This cross-sectional study of a convenient sample encompassed 1400 students in Health Colleges at Princess Nora Bint Abdul Rahman University, Riyadh, Saudi Arabia was conducted between December 2013 and February 2014. A self-administrated questionnaire was distributed to all participants. Data collected included socio-demographic data, knowledge of cervical cancer risk factors and clinical presentation, Pap smear, and HPV vaccine acceptance. The questionnaire reliability as tested by Cronbach’s alpha was 0.82. Results: The response rate was 89.9%, and data analysis revealed that 95.7% of students had poor knowledge level. The Pap smear was poorly recognized as a screening tool, with 46.7% of students having heard of the test. Senior and medical students had a significantly higher knowledge score. Father’s health profession, high monthly income, and presence of cervical cancer among family members or friends increased the level of knowledge. Vaccine acceptance is influenced by its price, approximately 80% of students thought that an affordable vaccine price should not exceed 300 Saudi Riyals. Perceived barriers to the vaccine were fear of injections and vaccine side effects. Conclusion: There is a lack of knowledge and misinformation regarding cervical cancer, Pap smear, and HPV as a major risk factor for cancer of the cervix. These data can be used as a benchmark to formulate effective awareness programs. PMID:25316467

    In most cases the only knowledge an individual will receive with regards to their own body and its proper functioning is during their high school education. The aim of this study was to evaluate high school students' knowledge about basic physiology. The research was carried out in five, randomly chosen high schools in Krakow, Poland. Young people in the age of 17-19 years were asked to fill in the questionnaire designed by the authors. The first part of the survey included personal data. The second part contained 20 close-ended questions assessing students' knowledge about the basics of human physiology. Question difficulty varied from easy through average, and up to difficult. The maximum number of points to achieve was 20. One-thousand-and eighty-three (out of 1179 invited--91.86%) Polish high school students (63.25% female) filled in a 20-item questionnaire constructed by the authors regarding basic human physiology. The mean age of the group was 17.66 ± 0.80 years. The mean score among the surveyed was 10.15 ± 3.48 (range 0-20). Only 26.04% of students achieved a grade of 60% or more, and only one person obtained the highest possible score. Females achieved significantly better scores than males (10.49 ± 3.38 vs. 9.56 ± 3.56; p physiology, obtained better results than those in their third year who had already finished the biology course (10.70 ± 3.27 vs. 9.81 ± 3.74 respectively; p physiology (10.70 ± 3.27 vs. 9.63 ± 2.74 respectively; p = 0.003). Over 23% of students did not know that mature red blood cells do not have cell nuclei and a similar number of them answered that humans have 500,000 erythrocytes in 1 mm3 of blood. Over 32% believed that plasma does not participate in the transport of respiratory gases, and 31% believed that endocrine glands secrete hormones within their immediate vicinity and into the blood. Our research has shown that young people, especially men, often lack basic physiological knowledge needed to make conscious and

    Dogs are the most common pet animals worldwide. They may harbour a wide range of parasites with zoonotic potential, thus causing a health risk to humans. In Nigeria, epidemiological knowledge on these parasites is limited. In a community-based study, we examined 396 dogs in urban and rural areas of Ilorin (Kwara State, Central Nigeria) for ectoparasites and intestinal helminths. In addition, a questionnaire regarding knowledge and practices was applied to pet owners. Nine ectoparasite species belonging to four taxa and six intestinal helminth species were identified: fleas (Ctenocephalides canis, Pulex irritans, Tunga penetrans), mites (Demodex canis, Otodectes sp., Sarcoptes scabiei var. canis), ticks (Rhipicephalus sanguineus, Ixodes sp.), and lice (Trichodectes canis); and Toxocara canis, Ancylostoma sp., Trichuris vulpis, Dipylidium caninum, Taenidae and Strongyloides sp. Overall prevalence of ectoparasites was 60.4% and of intestinal helminths 68.4%. The occurrence of C. canis, R. sanguineus, T. canis, Ancylostoma sp. and T. vulpis was most common (prevalence 14.4% to 41.7%). Prevalence patterns in helminths were age-dependent, with T. canis showing a decreasing prevalence with age of host, and a reverse trend in other parasite species. Knowledge regarding zoonoses was very limited and the diseases not considered a major health problem. Treatment with antiparasitic drugs was more frequent in urban areas. Parasites of importance for human health were highly prevalent in Nigerian dogs. Interventions should include health education provided to dog owners and the establishment of a program focusing on zoonotic diseases.

    Full Text Available Objectives: to analyze the quality of life of "patients" with Human Immunodeficiency Virus and relate it to their socioeconomic profile, knowledge and attitudes toward sexuality. Method: crosssectional and analytical study with 201 individuals who are 50 years old or older. The Targeted Quality of Life and Aging Sexual Knowledge and Attitudes Scales were applied during interviews. Multiple Linear Regression was used in data analysis. Results: dimensions of quality of life more strongly compromised were disclosure worries (39.0, sexual function (45.9, and financial worries (55.6. Scores concerning knowledge and attitudes toward sexuality were 31.7 and 14.8, respectively. There was significant correlation between attitudes and the domains of overall function, health worries, medication worries, and HIV mastery. Conclusion: guidance concerning how the disease is transmitted, treated and how it progresses, in addition to providing social and psychological support, could minimize the negative effects of the disease on the quality of life of patients living with the Human Immunodeficiency Virus.

    Full Text Available Introduction Recent studies with Physiotherapy students pointed out for attitudes and conflicting perceptions on their learning process during the phase that precedes the clinical practice. One of those aspects is the human sexuality that appears in the close physical contact that demands Physiotherapists professional practices. Objective To build up the first educational/research instrument that evaluates the knowledge, the comfort and the attitudes of Physiotherapy undergraduate students (SKCAPS. Materials and methods From the literature we extracted three dimensions: knowledge, comfort and attitudes. Initially 50 items were created distributed in the three dimensions that went under the content evaluation, 47 items survived from this process and integrate the first version of SKCAPS. In empiric terms the intern coherence and the reliability of the instrument were tested in 248 students. Results The exploratory factorial analysis carried 37 items in 4 factors that explain 68% of the total variance of the answers of the subjects and that confirmed the proposed dimensions. The dimension comfort became separated in comfort and discomfort. The SKCAPS presented good reliability in terms of intern consistence alpha 0.861. Finally, the instrument was administered to 30 Physiotherapy students for evaluation of clarity following the exclusion of two items that resulted in averages below 8.5. Conclusions With the aim of improve the teaching/learning process, we propose the SKCAPS as the first worth and reliable instrument to evaluate the knowledge, the comfort, the discomfort and the attitudes regard of human sexuality among Physiotherapy students.

    Since licensure of HPV vaccine in 2006, HPV vaccine coverage among Romanian adolescents remains worryingly low. The objectives of the study were to assess the knowledge and attitudes towards HPV infection and vaccination among Romanian adolescents and to explore the barriers to HPV vaccination with a view to developing strategies for expanding primary HPV infection prevention. This study was conducted in Bucharest between April and June 2015. A total of 524 adolescents aged 16-18 years old were recruited from the first two general highschools in Bucharest (according to the admission grade) and completed a self-administered questionnaire including demographics, HPV related and Papanicolau smear test knowledge. Odds ratio and 95% confidence intervals were used to identify the strength of association. Logistic regression analysis was used to identify the effect of demographic characteristics on the level of knowledge and HPV vaccination rate. Associations were considered statistically significant at pHPV infection, HPV vaccine and Papanicolau smear test, that is, 20.22%, 67.92% and 22.9%, respectively. The overall vaccination rate for this group was 2.3%. The most common reason for not receiving the HPV vaccine was the lack of information (80.6%) followed by parents' concerns regarding safety (11%), fear of pain (5.59%) and not being sexually active (2.7%). However, 97.7% of the respondents declared interest in receiving more information about HPV. According to demographic characteristics, age at first sexual intercourse over 16 years old, monthly household income over one thousand euros and self-perceived good relationship with family members were statistically associated on a multivariate logistic regression analysis with a high HPV knowledge score and rate of vaccination. This study shows a low level of knowledge about HPV infection and prophylactic vaccination among Romanian adolescents which may be one of the most important factors for the alarmingly low HPV

    Nikola Tesla (1856-1943) was one of the greatest inventors in history and a key player in the revolution that led to the large-scale use of electricity. He also made important contributions to such diverse fields as x-rays, remote control, radio, the theory of consciousness or electromagnetism. In his honour, the international unit of magnetic induction was named after him. Yet, his fame is scarce in comparison with that of other inventors of the time, such as Edison, with whom he had several heated arguments. He was a rather odd, reserved person who lived for his inventions, the ideas for which came to him in moments of inspiration. In his autobiography he relates these flashes with a number of neuropsychiatric manifestations, which can be seen to include migraine auras, synaesthesiae, obsessions and compulsions.

He’ll be spending two months at CERN starting this March but, to get a flavour of what’s in store, he visited the Organization last week for a crash course in its inspiring activities.   Julius von Bismarck, taking a closer look... When we arrive to interview German artist Julius von Bismarck, he’s being given a presentation about antiprotons’ ability to kill cancer cells. The whiteboard in the room contains graphs and equations that might easily send a non-scientist running, yet as Julius puts it, “if I weren’t interested, I’d be asleep”. Given his numerous questions, he must have been fascinated. “This ‘introduction’ week has been exhilarating,” says Julius. “I’ve been able to interact ...

    Although NASA's preparations for the Apollo lunar missions had only a limited time to consider issues associated with the protection of the Moon from biological contamination and the quarantine of the astronauts returning to Earth, they learned many valuable lessons (both positive and negative) in the process. As such, those efforts represent the baseline of planetary protection preparations for sending humans to Mars. Neither the post-Apollo experience or the Shuttle and other follow-on missions of either the US or Russian human spaceflight programs could add many additional insights to that baseline. Current mission designers have had the intervening four decades for their consideration, and in that time there has been much learned about human-associated microbes, about Mars, and about humans in space that has helped prepare us for a broad spectrum of considerations regarding potential biological contamination in human Mars missions and how to control it. This paper will review the approaches used in getting this far, and highlight some implications of this history for the future development of planetary protection provisions for human missions to Mars. The role of NASA and ESA's planetary protection offices, and the aegis of COSPAR have been particularly important in the ongoing process.

  8. Switchable bio-inspired adhesives

    Geckos have astonishing climbing abilities. They can adhere to almost any surface and can run on walls and even stick to ceilings. The extraordinary adhesion performance is caused by a combination of a complex surface pattern on their toes and the biomechanics of its movement. These biological dry adhesives have been intensely investigated during recent years because of the unique combination of adhesive properties. They provide high adhesion, allow for easy detachment, can be removed residue-free, and have self-cleaning properties. Many aspects have been successfully mimicked, leading to artificial, bio-inspired, patterned dry adhesives, and were addressed and in some aspects they even outperform the adhesion capabilities of geckos. However, designing artificial patterned adhesion systems with switchable adhesion remains a big challenge; the gecko's adhesion system is based on a complex hierarchical surface structure and on advanced biomechanics, which are both difficult to mimic. In this paper, two approaches are presented to achieve switchable adhesion. The first approach is based on a patterned polydimethylsiloxane (PDMS) polymer, where adhesion can be switched on and off by applying a low and a high compressive preload. The switch in adhesion is caused by a reversible mechanical instability of the adhesive silicone structures. The second approach is based on a composite material consisting of a Nickel- Titanium (NiTi) shape memory alloy and a patterned adhesive PDMS layer. The NiTi alloy is trained to change its surface topography as a function of temperature, which results in a change of the contact area and of alignment of the adhesive pattern towards a substrate, leading to switchable adhesion. These examples show that the unique properties of bio-inspired adhesives can be greatly improved by new concepts such as mechanical instability or by the use of active materials which react to external stimuli.

    Rural residents of the United States have higher HPV-associated cancer incidence and mortality, and suboptimal HPV vaccine uptake compared to urban residents. This study aimed to assess differences in knowledge and awareness of HPV, the HPV vaccine, and HPV-associated cancers among rural and urban residents. We analyzed data from the Health Information National Trends Survey 2013-2017 on 10,147 respondents ages ≥18 years. Multivariable logistic regression analyses compared urban/rural differences in knowledge and awareness of HPV, associated cancers, and HPV vaccine. Models were adjusted for sex, age, race/ethnicity, education, household income, census region, health insurance, regular provider, internet use, and personal history of cancer. Overall, 67.2% and 65.8% of urban residents were aware of HPV and HPV vaccine, respectively, compared to only 55.8% and 58.6% of rural residents. Adjusted models illustrated that compared to urban residents, rural residents were less likely to be aware of HPV (OR = 0.68, 95% CI = 0.53-0.86) and HPV vaccine (OR = 0.78, 95% CI = 0.63-0.97). Among those who were aware of HPV, rural residents were less likely to know that HPV causes cervical cancer (OR = 0.62, 95% CI = 0.46-0.84) and that HPV can be transmitted through sexual contact (OR = 0.72, 95% CI = 0.56-0.94). No significant differences between rural and urban residents were noted for knowledge that HPV is transmitted sexually and that it causes oral, anal, and penile cancers. This study highlights significant rural health disparities in knowledge and awareness of HPV and the HPV vaccine compared to urban counterparts. Copyright © 2018 Elsevier Inc. All rights reserved.

It comprised approximately 60 talks on topically focused sessions devoted to: DNA mechanics DNA structure, interactions and aggregation Recognition of homologous genes Conformational dynamics, supercoiling and packing DNA compactization in viruses DNA-protein interaction and recognition DNA in confinement (pores and vesicles) Smart DNA (robotics, nano-architectures, switches, sensors and DNA electronics) The success of the conference was that it was not a meeting of a club of physicists interested in biology, but a meeting of physicists, carrying out important work widely published not only in physical but also biological journals, with the leading biologists who, personally, were keenly interested in learning what novelties physical methods and existing knowledge could offer them. They were equally eager to explain to physicists and mathematicians the most challenging paradigms of molecular biology research. The conference was opened by two inspiring high-impact talks, from a Director of the European Molecular Genetics Center in Trieste, Arturo Falaschi, the Editor of HFSP Journal (who sadly just passed away last month), and from a scientist of the next generation, Lynn Zechiedrich, Professor of Baylor Medical School and former co-worker of the late Nick Cozzarelly. Both showed astounding manifestations of the polymeric behavior of DNA, where physics is eagerly awaited like rain in the desert. However, at the whole conference about 40% of lectures were delivered by biologists. In this short article it is not possible to cover even the most exciting presentations, and I refer interested readers to the website [5] where further information can be found. I will outline below just a couple of issues. The conference revealed big progress in understanding the details of DNA mechanics, including its local sequence-dependent elastic properties.

    Emotion carries crucial qualities of the human condition, representing one of the major challenges in artificial intelligence. Re-search in psychology and neuroscience in the past two to three decades has generated rich insights into the processes underlying human emotion. Cognition and emotion represent the two main pillars of the human psyche and human intelligence. While the hu-man cognitive system and cognitive brain has inspired and informed computer science and artificial intelligence, the future is ripe for the human emotion system to be integrated into artificial intelligence and robotic systems. Here, we review behavioral and neu-ral findings in human emotion perception, including facial emotion perception, olfactory emotion perception, multimodal emotion perception, and the time course of emotion perception. It is our hope that knowledge of how humans perceive emotion will help bring artificial intelligence strides closer to human intelligence.

  12. Biologically inspired robots as artificial inspectors

    Imagine an inspector conducting an NDE on an aircraft where you notice something is different about him - he is not real but rather he is a robot. Your first reaction would probably be to say 'it's unbelievable but he looks real' just as you would react to an artificial flower that is a good imitation. This science fiction scenario could become a reality at the trend in the development of biologically inspired technologies, and terms like artificial intelligence, artificial muscles, artificial vision and numerous others are increasingly becoming common engineering tools. For many years, the trend has been to automate processes in order to increase the efficiency of performing redundant tasks where various systems have been developed to deal with specific production line requirements. Realizing that some parts are too complex or delicate to handle in small quantities with a simple automatic system, robotic mechanisms were developed. Aircraft inspection has benefitted from this evolving technology where manipulators and crawlers are developed for rapid and reliable inspection. Advancement in robotics towards making them autonomous and possibly look like human, can potentially address the need to inspect structures that are beyond the capability of today's technology with configuration that are not predetermined. The operation of these robots may take place at harsh or hazardous environments that are too dangerous for human presence. Making such robots is becoming increasingly feasible and in this paper the state of the art will be reviewed.

    Full Text Available This article compares arachnid-based Marvel and DC comics characters. The composition of a comic book character often has interesting ‘real-life’ influences. Given the strong connection between arachnids (especially spiders, scorpions and mites, all belonging to the zoological class 'Arachnida' and human beings it is not surprising that they have inspired many fictional characters. We recorded 84 Marvel Comics characters and 40 DC Comics characters, detailed in the dataset that accompanies the article (Da-Silva 2014. Most characters have been created recently, since the 1990s. Marvel has significantly more arachnid characters than DC. As for taxonomic classification, the characters were based mostly on spiders (zoological order 'Araneae'. Of the total characters, the majority are human beings, but an overwhelming number have at least some typical arachnid features. Villains (60.91% of total are significantly more numerous, considering the sum of the two publishers. Arachnids have bad reputation for being dangerous (Thorp and Woodson 1976; Ruppert and Barnes 1996. Since the public usually considers spiders, scorpions and mites “harmful” in general, we expected a larger contingent of villains. However, there was no statistical difference between the amount of villains and heroes in Marvel characters. It did not happen probably due to the success of one character: the Amazing Spider-Man.

    BACKGROUND It is important to understand the knowledge that various groups of a population have about cervical cancer and human papillomavirus (HPV) and their attitudes toward HPV vaccination, as it will ultimately influence their decision-making for or against the acceptability of vaccines and other preventive methods. This study was designed to determine the level of knowledge and awareness about cervical cancer, HPV, and the HPV vaccine among Chinese women in Yunnan province. MATERIAL AND METHODS A survey was conducted in Yunnan province by the Laboratory of Molecular Virology in collaboration with the Yunnan First People's Hospital in Feb 2015. A total of 388 women were recruited and asked to participate in a questionnaire-based interview that collected information related to their awareness and knowledge about: (1) cervical cancer, (2) HPV and HPV vaccine and willingness to have their children receive vaccination, and (3) demographic characteristics. RESULTS A total of 388 HPV-positive women were included; 300/388 (73.3%) were Han, and 88/388 (22.7%) were other ethnicities. Overall, 204/388 (52.6%) of the women were aware of cervical cancer, with a significant difference between Han women and women of other ethnic groups (168/388, 56.0% and 36/88, 40.9%; P=0.015). Overall, 26.5% of the women were aware of the role of HPV in cervical cancer; 29.0% of the Han women and 18.2% of women of other ethnic groups were aware of this role of HPV (P=0.05). The knowledge that HPV infection leads to cervical cancer was higher among Han women (29.0%) compared to women of other ethnicities (18.2%). Knowledge about the HPV vaccine was very low in all ethnic groups, but the Han women were more willing to allow their children to be vaccinated before they become sexually active. A similar difference has also been found in women from various regions. CONCLUSIONS Although level of awareness and knowledge about cervical cancer was moderate, knowledge and awareness of HPV and the HPV

    Human activities can have a large influence on changes in the hydrological system and hydrological extremes, more than climate variability and climate change in some cases. However, there are currently only a limited number of studies which aim to quantify the human impact on hydrological droughts. Here we present a synthesis study of existing and new results that aims to summarize and quantify the anthropogenic impact on hydrological drought from case studies and observations. By combining a large number of case studies, we allow conclusions to be drawn about the effects of different human activities. This work suggests ways forward to increase our understanding on how human activities are influencing drought characteristics; invaluable information for water resource management and adaptation. During this project, the impact of different human activities (e.g. water abstraction, reservoir building, urbanisation, etc) on drought frequency, duration and deficit has been calculated in a consistent manner, allowing for an improved understanding to how they have impacted droughts. This consistent methodology is a necessary element for this comparative hydrology exercise, yet we use one which is flexible and applicable to different case study set ups and data availability. The methodology used here depends on available observation data, with three possible approaches: i) paired catchment approach; ii) upstream-downstream comparison; iii) observation modelling framework. The synthesised results of the existing and new case studies cover a number of human activities, hydro-climatic and socio-economic contexts. In particular, we remove the climate dependency in the results by using case studies from multiple climatic regions, including UK, Italy, US, Australia, Mexico and Chile. For groundwater abstraction, it is clear across all the relevant case studies that abstraction activities worsen drought events. This is especially prominent in the deficit volumes, with nearly all

    This paper proposes a novel joint time of arrival (TOA)/received signal strength indicator (RSSI)-based wireless capsule endoscope (WCE) location tracking method without prior knowledge of biological human tissues. Generally, TOA-based localization can achieve much higher localization accuracy than other radio frequency-based localization techniques, whereas wireless signals transmitted from a WCE pass through various kinds of human body tissues, as a result, the propagation velocity inside a human body should be different from one in free space. Because the variation of propagation velocity is mainly affected by the relative permittivity of human body tissues, instead of pre-measurement for the relative permittivity in advance, we simultaneously estimate not only the WCE location but also the relative permittivity information. For this purpose, this paper first derives the relative permittivity estimation model with measured RSSI information. Then, we pay attention to a particle filter algorithm with the TOA-based localization and the RSSI-based relative permittivity estimation. Our computer simulation results demonstrates that the proposed tracking methods with the particle filter can accomplish an excellent localization accuracy of around 2 mm without prior information of the relative permittivity of the human body tissues.

    Full Text Available The diagnosis of the current European societies, which are made possible through the production of scientific knowledge and technical, is simple in its formulation. They are societies in constant knowledge creation.  Given socio-economic and working conditions, implemented from the neo-liberal model of society, the abstract knowledge, associated with the profit of a few over the many, is leading the cultural logic of knowledge societies, without any axiological hesitation, That is to say, without postulating and discerning common goals and values ​​that can motivate human beings to live for the human journey. Thus, the current European societies, but not only them, are knowledge societies, (because they live in the continuous creation of technical and scientific knowledge. At the same time, companies are axiologically dismantled. They are societies that do not have been axiologically oriented. If humanity does not recover and increase this constitutive dimension, may not be feasible in human form. Our reflection presents a proposal for an axiological epistemology (M.

    Limited data exist on the effect of clinical trial participation on sexual behavioural change. Two hundred female sex workers working in Lima, Peru received human papillomavirus (HPV) vaccine in either the standard (0, 2, 6 months) or modified (0, 3, 6 months) schedule. Participants received comprehensive screening and treatment for sexually transmitted infections (STIs), counselling on safe sex practices, education about HPV and the HPV vaccine, contraceptives (oral and condoms) and family planning at each visit. We assessed vaccine completion rates, change in sexual practices, and changes in HPV knowledge before and after participation in the vaccine trial. There were high rates of vaccine completion, 91% overall. The estimated number of reported new and total clients over a 30-day period decreased significantly (P Knowledge about HPV and HPV-related disease increased among all participants. In addition, all participants listed at least one preventive strategy during the month 7 follow-up survey.

    The use of bio-inspiration for the development of new products and devices requires new educational tools for students consisting of appropriate design and manufacturing technologies, as well as curriculum. At the University of Maryland, new educational tools have been developed that introduce bio-inspired product realization to undergraduate mechanical engineering students. These tools include the development of a bio-inspired design repository, a concurrent fabrication and assembly manufacturing technology, a series of undergraduate curriculum modules and a new senior elective in the bio-inspired robotics area. This paper first presents an overview of the two new design and manufacturing technologies that enable students to realize bio-inspired products, and describes how these technologies are integrated into the undergraduate educational experience. Then, the undergraduate curriculum modules are presented, which provide students with the fundamental design and manufacturing principles needed to support bio-inspired product and device development. Finally, an elective bio-inspired robotics project course is present, which provides undergraduates with the opportunity to demonstrate the application of the knowledge acquired through the curriculum modules in their senior year using the new design and manufacturing technologies.

    2014-01-01

    Genetic variability in the species group Echinococcus granulosus sensu lato is well recognised as affecting intermediate host susceptibility and other biological features of the parasites. Molecular methods have allowed discrimination of different genotypes (G1-10 and the 'lion strain'), some of which are now considered separate species. An accumulation of genotypic analyses undertaken on parasite isolates from human cases of cystic echinococcosis provides the basis upon which an assessment is made here of the relative contribution of the different genotypes to human disease. The allocation of samples to G-numbers becomes increasingly difficult, because much more variability than previously recognised exists in the genotypic clusters G1-3 (=E. granulosus sensu stricto) and G6-10 (Echinococcus canadensis). To accommodate the heterogeneous criteria used for genotyping in the literature, we restrict ourselves to differentiate between E. granulosus sensu stricto (G1-3), Echinococcus equinus (G4), Echinococcus ortleppi (G5) and E. canadensis (G6-7, G8, G10). The genotype G1 is responsible for the great majority of human cystic echinococcosis worldwide (88.44%), has the most cosmopolitan distribution and is often associated with transmission via sheep as intermediate hosts. The closely related genotypes G6 and G7 cause a significant number of human infections (11.07%). The genotype G6 was found to be responsible for 7.34% of infections worldwide. This strain is known from Africa and Asia, where it is transmitted mainly by camels (and goats), and South America, where it appears to be mainly transmitted by goats. The G7 genotype has been responsible for 3.73% of human cases of cystic echinococcosis in eastern European countries, where the parasite is transmitted by pigs. Some of the samples (11) could not be identified with a single specific genotype belonging to E. canadensis (G6/10). Rare cases of human cystic echinococcosis have been identified as having been caused by

    Bravo, Paulina; Cofré, Hernán

    2016-11-01

    This work explores how pedagogical content knowledge (PCK) on evolution was modified by two biology teachers who participated in a professional development programme (PDP) that included a subsequent follow-up in the classroom. The PDP spanned a semester and included activities such as content updates, collaborative lesson planning, and the presentation of planned lessons. In the follow-up part, the lessons were videotaped and analysed, identifying strategies, activities, and conditions based on student learning about the theory of evolution. Data were collected in the first round with an interview before the training process, identifying these teachers' initial content representation (CoRe) for evolution. Then, a group interview was conducted after the lessons, and, finally, an interview of stimulated recall with each teacher was conducted regarding the subject taught to allow teachers to reflect on their practice (final CoRe). This information was analysed by the teachers and the researchers, reflecting on the components of the PCK, possible changes, and the rationale behind their actions. The results show that teachers changed their beliefs and knowledge about the best methods and strategies to teach evolution, and about students' learning obstacles and misconceptions on evolution. They realised how a review of their own practices promotes this transformation.

    NASA's Human Research Program (HRP) and Space Life Sciences Directorate (SLSD), not unlike many NASA organizations today, struggle with the inherent inefficiencies caused by dependencies on heterogeneous data systems and silos of data and information spread across decentralized discipline domains. The capture of operational and research-based data/information (both in-flight and ground-based) in disparate IT systems impedes the extent to which that data/information can be efficiently and securely shared, analyzed, and enriched into knowledge that directly and more rapidly supports HRP's research-focused human system risk mitigation efforts and SLSD s operationally oriented risk management efforts. As a result, an integrated effort is underway to more fully understand and document how specific sets of risk-related data/information are generated and used and in what IT systems that data/information currently resides. By mapping the risk-related data flow from raw data to useable information and knowledge (think of it as the data supply chain), HRP and SLSD are building an information architecture plan to leverage their existing, shared IT infrastructure. In addition, it is important to create a centralized structured tool to represent risks including attributes such as likelihood, consequence, contributing factors, and the evidence supporting the information in all these fields. Representing the risks in this way enables reasoning about the risks, e.g. revisiting a risk assessment when a mitigation strategy is unavailable, updating a risk assessment when new information becomes available, etc. Such a system also provides a concise way to communicate the risks both within the organization as well as with collaborators. Understanding and, hence, harnessing the human system risk-related data supply chain enhances both organizations' abilities to securely collect, integrate, and share data assets that improve human system research and operations.

    Regarding this failure to take such life processes into account, and given its propensity for generalization, science stood out among these spheres as placing an excessive weight on positivist values that by their very nature disregarded anything that could not be classified as such. This approach was in stark contrast with the open tradition upheld by Miguel de Unamuno that would be eagerly taken up by Spanish philosophy in the twentieth century. From the perspective of that philosophy it is, therefore, worth asking whether all of those aspects and elements (not only those that form part of any given human life but also those belonging to the other two main spheres of culture – art and morality – displaced by scientism because they were not positive or verifiable through experiment, because they did not lend themselves to being understood using a rationalist or logical/scientific reasoning were not also human. Was their rejection justified?

    In this short review we will show how the new scientific development mainly born in the western countries has produced since the end of 1700s an enormous increase in the level of life and of the number of their inhabitant, as never happened since the beginning of the human species. With the export of the scientific and technological culture in the other countries, like eastern Europe, in north and south America, and later in China and India (to quote the main examples), also their welfare condition have increased or are developing now. For what is concerning the second part of this short review, we try to explain why the most important future needs would be to insert, step by step, the developing countries inside the community of "interacting minds", in order to propagate the scientific culture (but not only) and to make it evolving by the contribution of the full humanity.

    Full Text Available Human embryonic stem cells, which are derived from the inner cell mass of the blastocyst, have become an object of intense study over the last decade. They possess two unique properties that distinguish them from many other cell types: (i the ability to self-renew indefinitely in culture under permissive conditions, and (ii the pluripotency, defined as the capability of giving rise to all cell types of embryonic lineage under the guidance of the appropriate developmental cues. The focus of many recent efforts has been on the elucidating the signaling pathways and molecular networks operating in human embryonic stem cells. These cells hold great promise in cell-based regenerative therapies, disease modeling, drug screening and testing, assessing genotoxic and mutagenic risks associated with exposures to a variety of environmental factors, and so forth. Ionizing radiation is ubiquitous in nature, and it is widely used in diagnostic and therapeutic procedures in medicine. In this paper, our goal is to summarize the recent progress in understanding how human embryonic stem cells respond to ionizing radiation exposures, using novel methodologies based on “omics” approaches, and to provide a critical discussion of what remains unknown; thus proposing a roadmap for the future research in this area.

    Scientific literature suggests that human papillomavirus (HPV) infection may be associated with oral squamous cell carcinoma (OSCC). However, knowledge regarding HPV-OSCC link among oral health professionals (OHP) has been insufficient. So, the aim of this study was to assess the knowledge about HPV associated OSCC among OHP working in dental faculties in Malaysia. Ethical committee of the University approved this study. A validated, pre-tested questionnaire was sent electronically to 224 OHP. Questionnaire collected information regarding demography, knowledge about HPV-OSCC link, HPV vaccine, and willingness to educate patients about HPV OSCC link among the participants of this cross-sectional study. Data collected was analysed using "Stata/IC-13" and was summarised using descriptive statistics like frequency, percentage, mean and standard deviation. Out of 179 participants, around 39% of the participant's opined virus was not a causative factor for OSCC. Around, 44% replied posterior portion of the tongue/oro-pharynx was the commonest site for HPV related OSCC, whereas 29% replied that lateral border of the tongue was the common site for HPV related OSCC. Forty one percent educated patients regarding HPV infection being a causative factor for OSCC. HPV vaccine can prevent OSCC was stated by 70% OHP. Only 12% were aware of the availability of HPV vaccine in Malaysia. Majority (99%), agreed that there is a need to offer continuing education programmes to dentists highlighting advances and preventive strategies in the fight against OSCC. Substantial increase in awareness is required among OHP regarding HPV-OSCC link.

    Cervical cancer is one of the commonest cancers among women all over the world. The association of cervical cancer with human papilloma virus (HPV) is well established. Knowledge about the causal relationship between HPV and cervical cancer is important to make appropriate, evidence-based health care choices. In this context we conducted a community based study among women about the knowledge, attitude and practice about HPV infections and their health effects. A cross sectional interview based house to house survey was conducted with a validated data collection tool covering sociodemographic factors, knowledge, attitude and practice about HPV and its health effects, among 1020 women from a rural village, Perdoor, in Udupi district, Karnataka, India in 2013-14. The mean age of participants was 38.9 years (SD=12.6). Study participants showed a high literacy rate (85.7%). Only 2.4% of sexually exposed women had undergone Pap smear testing. Partners of 4.4%women had undergone circumcision and they belonged to the Muslim community. Male condom usage was reported by 26 women (2.6%). However, none of the participants had heard of HPV and its health effects. This community based study found complete ignorance about HPV among rural South Indian women in spite of a high literacy level.

    2012-01-01

    Lacking a coordinated effort in utilizing data and tracking program outcomes, one agency developed a Quality Management (QM) division to facilitate and manage more effective data use. To support this process, the agency sought to develop a collective, agency-wide understanding and investment in improving and measuring client outcomes. Similarly, the agency also focused efforts on creating a culture of transparency and accountability, with goals of improving service, increasing agency integrity, meeting regulatory compliance, and engaging in effective risk management. Operationalizing the QM initiative involved developing procedures, systems, and guidelines that would facilitate the generation of reliable and accurate data that could be used to inform program change and decision-making. This case study describes this agency's experience in successfully creating and implementing a QM initiative aimed at engaging in greater knowledge sharing. Copyright © Taylor & Francis Group, LLC

  20. Information and Knowledge Management in the Scope of the Information Security practices: the human factor within Organizations

    Directory of Open Access Journals (Sweden)

    Luciana Emirena Santos Carneiro

    2013-08-01

    Full Text Available The security of informational assets has always been a corporate requirement. These assets can be scaled in three main spheres, namely, people, organizational processes and technologies. The internet, the web, the broadcast of networks, and the growing presence of technology both in people's lives and in organizational contexts have caused profound transformations in the intrinsic processes that constitute personal and organizational routines. On the one hand, these changes provided by the technological progress have fostered competitiveness and decentralization; on the other hand, they require better management, control, security and protection for information and knowledge. This article presents the results of an investigation within information security realm, focusing on the human aspects of knowledge and information management related to security practices. Using a quality-quantitative approach, we identify behavioral actions and profiles of employees of a company in the field of healthcare, which reveal some connections with information security failures. We conclude that the human element is a relevant variable, even a critical one, for the management of information security in organizations.

  1. Biologically-inspired soft exosuit.

    Asbeck, Alan T; Dyer, Robert J; Larusson, Arnar F; Walsh, Conor J

    2013-06-01

    In this paper, we present the design and evaluation of a novel soft cable-driven exosuit that can apply forces to the body to assist walking. Unlike traditional exoskeletons which contain rigid framing elements, the soft exosuit is worn like clothing, yet can generate moments at the ankle and hip with magnitudes of 18% and 30% of those naturally generated by the body during walking, respectively. Our design uses geared motors to pull on Bowden cables connected to the suit near the ankle. The suit has the advantages over a traditional exoskeleton in that the wearer's joints are unconstrained by external rigid structures, and the worn part of the suit is extremely light, which minimizes the suit's unintentional interference with the body's natural biomechanics. However, a soft suit presents challenges related to actuation force transfer and control, since the body is compliant and cannot support large pressures comfortably. We discuss the design of the suit and actuation system, including principles by which soft suits can transfer force to the body effectively and the biological inspiration for the design. For a soft exosuit, an important design parameter is the combined effective stiffness of the suit and its interface to the wearer. We characterize the exosuit's effective stiffness, and present preliminary results from it generating assistive torques to a subject during walking. We envision such an exosuit having broad applicability for assisting healthy individuals as well as those with muscle weakness.

  2. Fracture Mechanics: Inspirations from Nature

    Directory of Open Access Journals (Sweden)

    David Taylor

    2014-10-01

    Full Text Available In Nature there are many examples of materials performing structural functions. Nature requires materials which are stiff and strong to provide support against various forces, including self-weight, the dynamic forces involved in movement, and external loads such as wind or the actions of a predator. These materials and structures have evolved over millions of years; the science of Biomimetics seeks to understand Nature and, as a result, to find inspiration for the creation of better engineering solutions. There has been relatively little fundamental research work in this area from a fracture mechanics point of view. Natural materials are quite brittle and, as a result, they have evolved several interesting strategies for preventing failure by crack propagation. Fatigue is also a major problem for many animals and plants. In this paper, several examples will be given of recent work in the Bioengineering Research Centre at Trinity College Dublin, investigating fracture and fatigue in such diverse materials as bamboo, the legs and wings of insects, and living cells.

    Full Text Available Abstract Background Dogs are the most common pet animals worldwide. They may harbour a wide range of parasites with zoonotic potential, thus causing a health risk to humans. In Nigeria, epidemiological knowledge on these parasites is limited. Methods In a community-based study, we examined 396 dogs in urban and rural areas of Ilorin (Kwara State, Central Nigeria for ectoparasites and intestinal helminths. In addition, a questionnaire regarding knowledge and practices was applied to pet owners. Results Nine ectoparasite species belonging to four taxa and six intestinal helminth species were identified: fleas (Ctenocephalides canis, Pulex irritans, Tunga penetrans, mites (Demodex canis, Otodectes sp., Sarcoptes scabiei var. canis, ticks (Rhipicephalus sanguineus, Ixodes sp., and lice (Trichodectes canis; and Toxocara canis, Ancylostoma sp., Trichuris vulpis, Dipylidium caninum, Taenidae and Strongyloides sp. Overall prevalence of ectoparasites was 60.4% and of intestinal helminths 68.4%. The occurrence of C. canis, R. sanguineus, T. canis, Ancylostoma sp. and T. vulpis was most common (prevalence 14.4% to 41.7%. Prevalence patterns in helminths were age-dependent, with T. canis showing a decreasing prevalence with age of host, and a reverse trend in other parasite species. Knowledge regarding zoonoses was very limited and the diseases not considered a major health problem. Treatment with antiparasitic drugs was more frequent in urban areas. Conclusion Parasites of importance for human health were highly prevalent in Nigerian dogs. Interventions should include health education provided to dog owners and the establishment of a program focusing on zoonotic diseases.

    2013-01-01

    We present a biologically inspired actuator exhibiting a novel pumping action. The design of the ‘artificial heartbeat’ actuator is inspired by physical principles derived from the structure and function of the human heart. The actuator employs NiTi artificial muscles and is powered by electrical energy generated by microbial fuel cells (MFCs). We describe the design and fabrication of the actuator and report the results of tests conducted to characterize its performance. This is the first artificial muscle-driven pump to be powered by MFCs fed on human urine. Results are presented in terms of the peak pumping pressure generated by the actuator, as well as for the volume of fluid transferred, when the actuator was powered by energy stored in a capacitor bank, which was charged by 24 MFCs fed on urine. The results demonstrate the potential for the artificial heartbeat actuator to be employed as a fluid circulation pump in future generations of MFC-powered robots (‘EcoBots’) that extract energy from organic waste. We also envisage that the actuator could in the future form part of a bio-robotic artwork or ‘bio-automaton’ that could help increase public awareness of research in robotics, bio-energy and biologically inspired design.

    2012-04-25

    Biology is curved, soft and elastic; silicon wafers are not. Semiconductor technologies that can bridge this gap in form and mechanics will create new opportunities in devices that adopt biologically inspired designs or require intimate integration with the human body. This talk describes the development of ideas for electronics that offer the performance of state-of-the-art, wafer- based systems but with the mechanical properties of a rubber band. We explain the underlying materials science and mechanics of these approaches, and illustrate their use in (1) bio- integrated, ‘tissue-like’ electronics with unique capabilities for mapping cardiac and neural electrophysiology, and (2) bio-inspired, ‘eyeball’ cameras with exceptional imaging properties enabled by curvilinear, Petzval designs.

    Background: Human papilloma virus (HPV) is a virus that causes genital warts and a range of different cancer types. Vaccination against HPV was introduced in Norway in 2009, for girls in the 7th grade, as a part of the Norwegian Childhood Vaccination Program. There has been much discussion about the HPV-vaccine before and after the vaccine introduction. The uptake of HPV-vaccination is lower (67-75%) than for other vaccines. The lower vaccine uptake may be explained by lack of information abo...

    2013-01-01

    Biological systems are a source of inspiration in the development of small autonomous sensor nodes. The two major types of optical vision systems found in nature are the single aperture human eye and the compound eye of insects. The latter are among the most compact and smallest vision sensors. The eye is a compound of individual lenses with their own photoreceptor arrays.  The visual system of insects allows them to fly with a limited intelligence and brain processing power. A CMOS image sensor replicating the perception of vision in insects is discussed and designed in this book for industrial (machine vision) and medical applications. The CMOS metal layer is used to create an embedded micro-polarizer able to sense polarization information. This polarization information is shown to be useful in applications like real time material classification and autonomous agent navigation. Further the sensor is equipped with in pixel analog and digital memories which allow variation of the dynamic range and in-pixel b...

    When you ask people whether investment in basic science is worth it, the answer you get is an overwhelming ‘yes’… followed by a pause, and then a question: ‘what’s the immediate benefit?’ Of course we have answers.   Basic research at CERN expands the pool of human knowledge. It inspires the young, and provides an important impetus to scientific and technical education. Applications of CERN technology are to be found in many domains, and the results of basic science provide the seeds for applied research. All this is clear and well established, but we can always do more, and that’s why I was particularly impressed with an event that took place at CERN last week.

    Nakano, Masataka; Nakajima, Miki

    2018-05-01

    Understanding the factors causing inter- and intra-individual differences in drug metabolism potencies is required for the practice of personalized or precision medicine, as well as for the promotion of efficient drug development. The expression of drug-metabolizing enzymes is controlled by transcriptional regulation by nuclear receptors and transcriptional factors, epigenetic regulation, such as DNA methylation and histone acetylation, and post-translational modification. In addition to such regulation mechanisms, recent studies revealed that microRNAs (miRNAs), endogenous ~22-nucleotide non-coding RNAs that regulate gene expression through the translational repression and degradation of mRNAs, significantly contribute to post-transcriptional regulation of drug-metabolizing enzymes. Areas covered: This review summarizes the current knowledge regarding miRNAs-dependent regulation of drug-metabolizing enzymes and transcriptional factors and its physiological and clinical significance. We also describe recent advances in miRNA-dependent regulation research, showing that the presence of pseudogenes, single-nucleotide polymorphisms, and RNA editing affects miRNA targeting. Expert opinion: It is unwavering fact that miRNAs are critical factors causing inter- and intra-individual differences in the expression of drug-metabolizing enzymes. Consideration of miRNA-dependent regulation would be a helpful tool for optimizing personalized and precision medicine.

  13. Human resource management in post-conflict health systems: review of research and knowledge gaps.

    2014-01-01

    In post-conflict settings, severe disruption to health systems invariably leaves populations at high risk of disease and in greater need of health provision than more stable resource-poor countries. The health workforce is often a direct victim of conflict. Effective human resource management (HRM) strategies and policies are critical to addressing the systemic effects of conflict on the health workforce such as flight of human capital, mismatches between skills and service needs, breakdown of pre-service training, and lack of human resource data. This paper reviews published literatures across three functional areas of HRM in post-conflict settings: workforce supply, workforce distribution, and workforce performance. We searched published literatures for articles published in English between 2003 and 2013. The search used context-specific keywords (e.g. post-conflict, reconstruction) in combination with topic-related keywords based on an analytical framework containing the three functional areas of HRM (supply, distribution, and performance) and several corresponding HRM topic areas under these. In addition, the framework includes a number of cross-cutting topics such as leadership and governance, finance, and gender. The literature is growing but still limited. Many publications have focused on health workforce supply issues, including pre-service education and training, pay, and recruitment. Less is known about workforce distribution, especially governance and administrative systems for deployment and incentive policies to redress geographical workforce imbalances. Apart from in-service training, workforce performance is particularly under-researched in the areas of performance-based incentives, management and supervision, work organisation and job design, and performance appraisal. Research is largely on HRM in the early post-conflict period and has relied on secondary data. More primary research is needed across the areas of workforce supply, workforce

    Awareness of HPV by the target population is an important determinant of vaccine acceptance. The aim of this study is to evaluate the awareness of HPV infection and acceptability of the HPV vaccines among Turkish college students. College students aged 18-30 who were attending a large public university in Ankara participated in this study. The participants were asked to complete a questionnaire to elicit demographic characteristics, awareness level of HPV and HPV vaccine, and willingness to be vaccinated. One thousand one hundred sixty students responded to the invitation email and completed the questionnaire. The mean scores of female students about HPV and HPV vaccine were 7.1/15 and 3.6/9, respectively, while these scores were 7.9/15 and 3.4/9 among male students, respectively. While 51 % percent of female and 33.5 % of male students had heard of HPV and 32.8 % and 18 % of them had heard of HPV vaccine, respectively, only 1.5 % of female and 0.4 % of male students had been vaccinated against HPV. A total of 507 students (43.7 %) had previously heard of HPV. Only 309 (26.6 %) of the participants had previously heard of the HPV vaccine, and 45.1 % of the students were willing to receive HPV vaccination. The main predictors for willingness to be vaccinated were the following: sexual experience, sexual behavior, past history of sexually transmitted infection (STI), and knowledge about HPV and HPV vaccine. Higher awareness levels of HPV and HPV vaccine are significantly related to greater willingness to be vaccinated, and the main reasons for rejecting the vaccine were insufficient information about the vaccine and possible unknown side effects.

    Human papillomavirus (HPV) infection is a common cause for genital warts and cervical cancer. Developing countries in the Middle East such as Lebanon are traditionally considered to be conservative societies with low incidence of sexually transmitted infections. However, nowadays, there is an unexpected increase in the incidence of HPV infections among Middle Eastern females. Thus, the objective of this study is to assess the behavioral perceptions of HPV vaccination among female students attending an academic institution in Lebanon. This cross-sectional study invited 512 students to complete a self-administered questionnaire that assessed the knowledge, attitudes, and intentions towards HPV vaccination. Data analysis included the calculation of knowledge scores ranging from 0 to 100, attitude scores ranging from most positive (1) to most negative (5), and intention scores ranging from lowest intention (0) to highest intention (10). With a response rate of n=215 (42%), 36.5% never heard of the vaccine before, and only 16.5% were already HPV vaccinated. The median knowledge score of 52.7% ± 1.71 reflects poor to moderate knowledge. Still, the median attitude score of 2.47 ± 0.05 shows a general positive attitude towards HPV vaccination where most of the participants agreed that female college students in Lebanon have a good chance of contracting HPV (62.1%) and that all gynecologists should recommend the vaccine (76.0%). Students in graduate programs, health related majors, and those who are vaccinated had significantly higher knowledge scores compared with students in undergraduate programs, non-health related majors, and HPV non-vaccinated students, respectively. Finally, the survey helped in increasing the intention to obtain HPV vaccine as the intention score increased significantly from 5.24 ± 0.27 before the students went through the survey to 6.98 ± 0.22 after the students completed the survey. Our study highlights the importance of offering guidance to

    The International Space Station (ISS) has a unique ability to capture the imagination of both students and teachers worldwide. Since 2000, the presence of humans onboard ISS has provided a foundation for numerous educational activities aimed at capturing that interest and motivating study in the sciences, technology, engineering and mathematics (STEM). Over 43 million students around the world have participated in ISS-related educational activities. Projects such as YouTube Space Lab, Sally Ride Earth Knowledge-based Acquired by Middle Schools (EarthKAM), SPHERES (Synchronized Position Hold Engage and Reorient Experimental Satellites) Zero-Robotics, Tomatosphere, and MAI-75 events among others have allowed for global student, teacher and public access to space through student classroom investigations and real-time audio and video contacts with crewmembers. Educational activities are not limited to STEM but encompass all aspects of the human condition. This is well illustrated in the Uchu Renshi project, a chain poem initiated by an astronaut while in space and continued and completed by people on Earth. With ISS operations now extended to 2024, projects like these and their accompanying educational materials are available to more students around the world. From very early on in the program's history, students have been provided with a unique opportunity to get involved and participate in science and engineering projects. Many of these projects support inquiry-based learning that allows students to ask questions, develop hypothesis-derived experiments, obtain supporting evidence and identify solutions or explanations. This approach to learning is well-published as one of the most effective ways to inspire students to pursue careers in scientific and technology fields. Ever since the first space station element was launched, a wide range of student experiments and educational activities have been performed, both individually and collaboratively, by all the

  5. When does quality improvement count as research? Human subject protection and theories of knowledge.

    Science.gov (United States)

    Lynn, J

    2004-02-01

    The publication of insights from a quality improvement project recently precipitated a ruling by the lead federal regulatory agency that regulations providing protection for human subjects of research should apply. The required research review process did not match the rapid changes, small samples, limited documentation, clinician management, and type of information commonly used in quality improvement. Yet quality improvement can risk harm to patients, so some review might be in order. The boundaries and processes are not clear. Efforts have been made to determine what constitutes "research", but this has proved difficult and often yields irrational guidance with regard to protection of patients. Society needs a workable way to separate activities that will improve care, on the one hand, and those that constitute research, on the other. Practitioners who lead both quality improvement and research projects claim that those which rapidly give feedback to the care system that generated the data, aiming to change practices within that system, are "quality improvement" no matter whether the findings are published, whether the project is grant funded, and whether contemporaneous controls do not have the intervention. This criterion has not previously been proposed as a possible demarcation. The quandaries of which projects to put through research review and how to ensure ethical implementation of quality improvement need to be resolved.

    Historically, cadavers have been used for the study of anatomy. Nowadays, the territorial and legal limitations of this approach have led to the introduction of alternative teaching methods such as the use of practical exercise consisting of dissection and observation of animal organs. The aim of this study was to evaluate the use of practical training on animal organs compared with the traditional method of anatomy teaching, based on the dissection of human cadavers. In this study, we seek to demonstrate the usefulness of practical exercise on animal organs. This practical training was held a week after the series of lectures, thus leaving time for the students to learn and understand the topics discussed. Immediately after the lecture, all of the students completed a preliminary test to assess the immediate effect of the lecture. Immediately before the practical exercise, both control and experimental groups completed a second test to assess the effectiveness of personal study. Immediately after practical training, a third test was completed by the experimental group and the control group (no practical activity on animal organs) to highlight the added value of hands-on practice in addition to the lecture. Data obtained from statistical analysis showed a panatomy learning between control and experimental groups. Thus, the results of this study emphasize the utility of practical training on animal organs in learning and understanding anatomy, considering the limitations of the use of cadavers.

    2013-01-01

    This two-study paper examined stigma toward women with cervical cancer. Cervical cancer is caused by human papillomavirus (HPV), a sexually transmitted infection (STI). For Study 1, participants (N = 352) were randomly assigned to one of four conditions in which they read a brief description of a patient with either cervical or ovarian cancer in which the cause of the patient's cancer was either specified (cervical: HPV, a STI vs. ovarian: family history) or unspecified. Participants in the cervical cancer/cause-specified condition rated the patient as more dirty, dishonest and unwise, and reported feeling more moral disgust and 'grossed out' than participants in the cervical cancer/cause-unspecified condition. For Study 2, participants (N = 126) were randomly assigned to read a vignette about a patient with cervical cancer in which the cause of cancer was either specified or unspecified. Consistent with Study 1, participants in the cause-specified condition rated the patient as more unwise, and reported feeling more moral disgust and 'grossed out' than participants in the cause-unspecified condition. These effects were mediated by attributions of blame toward the patient. Findings suggest that women with cervical cancer may be stigmatised and blame may play a role in this process.

    Full Text Available This paper summarises some recent developments in INSPIRE implementation from the JRC (Joint Research Centre point of view. The INSPIRE process started around 11 years ago and today, clear results and benefits can be seen. Spatial data are more accessible and shared more frequently between countries and at the European level. In addition to this, efficient, unified coordination and collaboration between different stakeholders and participants has been achieved, which is another great success. The JRC, as a scientific think-tank of the European Commission, has played a very important role in this process from the very beginning. This role is in line with its mission, which is to provide customer-driven scientific and technical support for the conception, development, implementation and monitoring of European Union (EU policies. The JRC acts as the overall technical coordinator of INSPIRE, but it also carries out the activities necessary to support the coherent implementation of INSPIRE, by helping member states in the implementation process. Experiences drawn from collaboration and negotiation in each country and at the European level will be of great importance in the revision of the INSPIRE Directive, which is envisaged for 2014.

    As one of the fastest growing ethnic minority groups in the United States, Korean American (KA) women experience a heightened cervical cancer burden. The advent of the human papillomavirus (HPV) vaccine offers an unprecedented opportunity to eliminate cervical cancer disparities in KA women. However, the uptake of HPV vaccine among KA adolescents remains suboptimal. Hence, we set out to explore knowledge, perceptions, and decision making about HPV vaccination among KA women. We conducted four focus groups of 26 KA women who participated in a community-based, randomized, controlled trial to promote breast and cervical cancer screening. Focus group data were analyzed using qualitative content analysis. Four main themes emerged from the focus groups: 1) limited awareness and knowledge of HPV vaccine, 2) perceptions and beliefs about HPV vaccination (acceptance, negative perceptions, ambivalence), 3) patterns of decision making about HPV vaccination (hierarchical, peer influenced, autonomous, and collaborative), and 4) promoting HPV education and information sharing in the Korean community. KA women are generally positive toward HPV vaccination, but lack awareness and knowledge about HPV. Culturally tailored HPV education programs based on KA women's decision-making patterns and effective information sharing by trustworthy sources in comfortable environments are suggested strategies to promote HPV vaccination in the KA community. The findings point to the need for a multilevel approach to addressing linguistic, cultural, and system barriers that the recent immigrant community faces in promoting HPV vaccinations. In the development of targeted interventions for KA women, educational strategies and patterns of decision making need to be considered. Copyright © 2015 Jacobs Institute of Women's Health.

    The epidemiology of oral cancer is changing. From 1988 to 2004, there has been a dramatic increase in Human Papilloma virus (HPV) positive oropharyngeal squamous cell carcinoma (OPC) in the U.S. At the same time there have been decreasing rates of OPC associated with the traditional risk factors of smoking and alcohol consumption. The epidemiology of oral cancer is changing. As the epidemiology changes, it is important that the dental community recognize these factors. The goal of this study was to assess the baseline level of knowledge about HPV and OPC within the Texas dental community. Practicing dentists and dental hygienists from Texas dental professional networks and dental students from the three Texas schools of dentistry were recruited to participate in the study. Participants were requested to access and complete a 7-item online survey. To ensure anonymity, a third party practice facilitator or department administrator disseminated the survey link to participants. Of the 457 surveys completed, 100% of respondents reported conducting oral soft tissue examinations at least annually. However, only 73% included the oropharynx in their exam. Less than 50% of dental professionals selected the correct location of the greatest increase in oral cancer incidence during the last 10 years. Less than 30% of each of the groups answered correctly in indicating the age group with the most rapidly increasing incidence of oral cancer. Approximately 40% of all groups indicated that a biopsy from the posterior oropharynx should be tested for HPV. Survey results across Texas dentists, dental hygienists, and Texas dental students demonstrated a lack of knowledge of the changing profile of oral cancer regarding HPV-associated OPC. This aim of this initial phase was to determine the baseline level of knowledge surrounding the risks associated with oropharyngeal cancer in the survey population. Our goal is to utilize these findings to develop educational interventions that will

    The present study examined the relationship between second-year medical students' group performance and individual performance in a collaborative-learning environment. In recent decades, university professors in the scientific and humanistic disciplines have successfully put into practice different modalities of collaborative approaches to teaching. Essentially, collaborative approach refers to a variety of techniques that involves the joint intellectual effort of a small group of students, which encourages interaction and discussion among students and professors. The present results show the efficacy of collaborative learning, which, furthermore, allowed students to participate actively in the physiology class. Average student's grades were significantly higher when they engaged in single-best-response, multiple-choice tests as a student team, compared with taking the same examinations individually. The method improved notably knowledge retention, as learning is more effective when performed in the context of collaborative partnership. A selected subset of questions answered wrongly in an initial test, both individually and collectively, was used on a second test to examine student retention of studied material. Grade averages were significantly improved, both individually and groupwise, when students responded to the subset of questions a second time, 1, 2, or 3 wk after the first attempt. These results suggest that the collaborative approach to teaching allowed a more effective understanding of course content, which meant an improved capacity for retention of human physiology knowledge.

    Full Text Available Abstract Background In order to be widely accepted by users, the implementation of a new health intervention requires them to be adequately informed about its clinical importance, benefits and risks. The aim of this study was to provide data on the knowledge of Italian adolescents and parents concerning human papillomavirus (HPV infection and its prevention in order to allow the development of adequate training programmes. Methods Between 2 May and 15 June 2008, we made a cross-sectional survey of 863 high school students and 2,331 parents of middle and high school students using two anonymously completed questionnaires covering the knowledge of HPV infection and related diseases, and attitudes to vaccinations. The approached schools were a convenience sample of the schools of the greater Milan area, Northern Italy. Results More mothers than fathers were aware that HPV infection could concern their children (58% vs 53%; p = 0.004 and were favourable towards vaccinating their children against HPV (68% vs 65%; p = 0.03; among the students, more females than males were aware that HPV infection could concern themselves (45% vs 26%; p vs 40%; p Conclusions Both students and parents seem to underestimate the likelihood of HPV infection, and this is associated with a lower propensity for vaccination. This is an important indication for future training programmes concerning HPV prevention designed to increase the acceptance of HPV vaccine in families.

    The parasite Echinococcus canadensis (G7) (phylum Platyhelminthes, class Cestoda) is one of the causative agents of echinococcosis. Echinococcosis is a worldwide chronic zoonosis affecting humans as well as domestic and wild mammals, which has been reported as a prioritized neglected disease by the World Health Organisation. No genomic data, comparative genomic analyses or efficient therapeutic and diagnostic tools are available for this severe disease. The information presented in this study will help to understand the peculiar biological characters and to design species-specific control tools. We sequenced, assembled and annotated the 115-Mb genome of E. canadensis (G7). Comparative genomic analyses using whole genome data of three Echinococcus species not only confirmed the status of E. canadensis (G7) as a separate species but also demonstrated a high nucleotide sequences divergence in relation to E. granulosus (G1). The E. canadensis (G7) genome contains 11,449 genes with a core set of 881 orthologs shared among five cestode species. Comparative genomics revealed that there are more single nucleotide polymorphisms (SNPs) between E. canadensis (G7) and E. granulosus (G1) than between E. canadensis (G7) and E. multilocularis. This result was unexpected since E. canadensis (G7) and E. granulosus (G1) were considered to belong to the species complex E. granulosus sensu lato. We described SNPs in known drug targets and metabolism genes in the E. canadensis (G7) genome. Regarding gene regulation, we analysed three particular features: CpG island distribution along the three Echinococcus genomes, DNA methylation system and small RNA pathway. The results suggest the occurrence of yet unknown gene regulation mechanisms in Echinococcus. This is the first work that addresses Echinococcus comparative genomics. The resources presented here will promote the study of mechanisms of parasite development as well as new tools for drug discovery. The availability of a high

    The primary objective of this study was to assess the knowledge of medical students and determine variation between different cultural groups. A secondary aim was to find out the willingness to pay for cervical cancer vaccination and the relationships between knowledge and attitudes towards Human Papillomavirus vaccination. A cross-sectional survey was conducted in a private medical university between June 2014 and November 2014 using a convenient sampling method. A total of 305 respondents were recruited and interviewed with standard questionnaires for assessment of knowledge, attitudes and practice towards human papilloma virus and their willingness to pay for HPV vaccination. Knowledge regarding human papilloma virus, human papilloma virus vaccination, cervical cancer screening and cervical cancer risk factors was good. Across the sample, a majority (90%) of the pupils demonstrated a high degree of knowledge about cervical cancer and its vaccination. There were no significant differences between ethnicity and the participants' overall knowledge of HPV infection, Pap smear and cervical cancer vaccination. Some 88% of participants answered that HPV vaccine can prevent cervical cancer, while 81.5% of medical students said they would recommend HPV vaccination to the public although fewer expressed an intention to receive vaccination for themselves.

    There is an immediate need to preserve existing knowledge in nuclear science and technology for peaceful applications for future generations, as it represents a valuable human capital asset. The development of an exciting vision for nuclear technology is prerequisite for attracting young scientists and professionals to seek careers in nuclear science and technology. Irrespective of current national energy policies, the need to maintain or even enhance the nuclear knowledge base and national capability will persist. In this way, the knowledge base will be available to meet requirements for evolving policy development. A number of IAEA advisory committees and technical meetings stressed the importance of preserving and further enhancing nuclear science and technology for socio-economic development. For nuclear science and technology to contribute to sustainable development requires knowledge and capacity on three levels: (a) basic nuclear science, (b) technology, (c) engineering and operation. There was unanimous consensus that IAEA has an obligation to lead activities towards preservation and enhancement of nuclear knowledge by complementing, and as appropriate supplementing, activities by governments, industry, academia and international organizations. International co-operation is of vital importance. Unless action is taken now, invaluable assets in critical nuclear knowledge and capacity will soon be lost. The IAEA is developing guidance documents on nuclear knowledge management including knowledge preservation and knowledge transfer in nuclear sector. This activity would assist nuclear organizations in MS to effectively apply this guidance, and to assist them in benchmarking their practices against those of other industry organizations. The present Working Material provides general principals for knowledge preservation in nuclear sector, which could be applied in different nuclear organization and in particular in Nuclear Power Plants.

    To study women's knowledge regarding the role of human papilloma virus (HPV) in cervical intraepithelial neoplasia and their attitudes toward the integration of HPV testing as part of routine follow-up of atypical squamous cell of uncertain significance/low-grade squamous intraepithelial lesion (ASCUS/LGSIL) abnormalities. Over a 12-month period, all women attending the University of Ottawa colposcopy clinic for evaluation and follow-up of ASCUS/LGSIL Pap smears were recruited. Demographic data included age, nature of the Pap smear abnormality, gravidity, parity, occupation and education level, smoking history, previous history of abnormal smears, colposcopic examination and treatment, and current method of contraception. The women were asked to rate their level of concern over their Pap smear abnormality, from 0 (not concerned) to 10 (very concerned). Women's knowledge regarding the role of HPV in cervical intraepithelial neoplasia and the rationale behind the use of HPV testing was assessed by the clinic nurse as being minimal, moderate, or good, as defined by pre-specified criteria. Upon explanation by the nurses of the results of the recent ALTS (ASCUS/LGSIL Triage Study) trial, the women were asked to state whether they preferred to continue with regular colposcopic surveillance every 6 months, or to use the results of the HPV test, if negative, to reduce the number of colposcopy examinations to one annually. Descriptive statistics and logistic regression analysis were used to identify significant demographic factors associated with the women's preference for incorporation of HPV testing in their follow-up. All P values less than.10 were considered to be statistically significant, due to the exploratory nature of the study. Of the 100 women who participated in the study, 42% presented with ASCUS. The mean age (+/- SD) of the women was 33.63 +/- 11.25 years (range, 18-75 years); 66% were office workers with at least a community college degree, 86% reported

    Medium-sized food manufacturing enterprises in Indonesia are significant in a number of contexts, in terms of their part to the national production (GDP) and their establishment to the employment. In term of their role to national production, manufacturing sector contributes the highest GDP by 85%. In this sector, food manufacturing subsector contributes the highest GDP. Nevertheless, they faced the same common problems: quality of human capital and sustainability issues. Previous government supplementary programs have been established to expand the human capital capability amongst medium enterprises. Adequate amount of fund has been apportioned to develop human capital, though, the medium enterprises sustainability is still in question. This study proposes and examines the human capital role from informal knowledge sharing perspective. By conducting qualitative approach through interviews to four informants in Indonesian medium-sized food manufacturing enterprises, a set of hypotheses is derived from this study for future quantitative study. This study indicates that human capital traits (diverse education background, employee skills, and employee experience) could leverage the practice of informal knowledge sharing. Constructs such as mutual trust and reciprocal intention could play as mediating variables, and cultural interpretation perspective could act as moderating factor to informal knowledge sharing effectiveness. In final, informal knowledge sharing is indicated to play as moderating variable for human capital policy and practice to support enterprise sustainability.

    Full Text Available One of the great mysteries of the brain is cognitive control. How can the interactions between millions of neurons result in behavior that is coordinated and appears willful and voluntary? There is consensus that it depends on the prefrontal cortex (PFC. Many PFC areas receive converging inputs from at least two sensory modalities. Inspired by human's innate ability to process and integrate information from disparate, network-based sources, we apply human-inspired information integration mechanisms to target detection in cognitive radar sensor network. Humans' information integration mechanisms have been modelled using maximum-likelihood estimation (MLE or soft-max approaches. In this paper, we apply these two algorithms to cognitive radar sensor networks target detection. Discrete-cosine-transform (DCT is used to process the integrated data from MLE or soft-max. We apply fuzzy logic system (FLS to automatic target detection based on the AC power values from DCT. Simulation results show that our MLE-DCT-FLS and soft-max-DCT-FLS approaches perform very well in the radar sensor network target detection, whereas the existing 2D construction algorithm does not work in this study.

    Background Human papillomavirus (HPV) vaccination targets high-risk HPV16/18 that cause 70% of all cancers of the cervix. In Australia there is a fully-funded, school-based National HPV Vaccination Program which has achieved vaccine initiation rate of 82% among age-eligible females. Improving HPV vaccination rates is important in the prevention of morbidity and mortality associated with HPV-related disease. This study aimed to identify factors and barriers associated with uptake of the HPV vaccine in the Australian Program. Methods Between 2011 and 2014, females aged 18–25 years, living in Victoria, Australia who were offered HPV vaccination between 2007 and 2009 as part of the National HPV Vaccination Program, living in Victoria, Australia were recruited into a a young women’s study examining effectiveness of the Australian National HPV Vaccination Program. Overall, 668 participants completed the recruitment survey, which collected data of participants’ demographics and HPV knowledge. In 2015 these participants were invited to complete an additional supplementary survey on parental demographics and attitudes towards vaccinations. Results In 2015, 417 participants completed the supplementary survey (62% response rate). Overall, 19% of participants were unvaccinated. In multivariate analyses, HPV vaccination was significantly associated with their being born in Australia (pvaccinations (pparents being main decision-makers for participants’ HPV vaccination (pHPV non-vaccination was parental concern about vaccine safety (43%). Compared with HPV-vaccinated participants, those unvaccinated were significantly more likely to be opposed to all vaccines, including HPV vaccines (pvaccinating their own children with all vaccines (p = 0.033), including HPV vaccines (pHPV vaccine acceptance. Conclusions Attitudes towards general health, vaccinations in general, as well as HPV vaccines are important in HPV vaccine uptake. Long-term monitoring of the knowledge, attitude

    Clinicians' recommendation for the human papillomavirus (HPV) vaccine appears to be an important driver of parental decisions about vaccination. Our aim was to synthesize the best available evidence exploring the perceptions and experiences regarding HPV vaccination, from the perspective of the US clinician. We conducted a comprehensive literature search of Academic Search Complete, CINAHL Plus, Communication & Mass Media Complete, Consumer Health Complete (EBSCOhost), ERIC, Health and Psychosocial Instruments, MEDLINE with full text, and PsycINFO databases. We identified 60 eligible articles: 48 quantitative and 12 qualitative. We extracted the following information: study purpose, use of theory, location, inclusion criteria, and health care provider classification. Results were organized into 5 categories: 1) clinicians' knowledge and beliefs about HPV and the HPV vaccine, 2) clinicians' attitudes and beliefs about recommending HPV vaccines, 3) clinicians' intention to recommend HPV vaccines, 4) clinicians' professional practices regarding HPV vaccination, and 5) patient HPV vaccination rates. Although clinicians were generally supportive of HPV vaccination, there was a discrepancy between clinicians' intentions, recommendation practices, and patient vaccination rates. Studies reported that clinicians tended not to provide strong, consistent recommendations, and were more likely to recommend HPV vaccines to girls versus boys and to older versus younger adolescents. Analyses revealed a number of facilitating factors and barriers to HPV vaccination at the clinician, parent/patient, and systems levels, including clinician knowledge, clinician beliefs, and office procedures that promote vaccination. This review provides an evidence base for multilevel interventions to improve clinician HPV vaccine recommendations and vaccination rates. Copyright © 2017 Academic Pediatric Association.

    The purpose of this study was to determine and compare the knowledge and attitudes toward human papillomavirus (HPV), HPV vaccine, Pap tests, and cervical cancer among US and Peruvian women. A convenience sample of 275 US women in Augusta, GA, and 702 Peruvian women living in or near Cusco, Peru, completed 22- or 21-item questionnaires, respectively. These questionnaires determined their knowledge about HPV, the HPV vaccine, Pap tests, and cervical cancer. Simple logistic regression was used to determine the relationship between location and language on the correct responses. Odds ratios (ORs) and 95% confidence intervals were calculated. US Spanish- (OR = 0.02), Quechua- (OR = 0.05), and Peru Spanish-speaking women (OR = 0.03) were significantly less likely to know that HPV causes cervical cancer compared with US non-Spanish-speaking women. US Spanish- (OR = 10.61, OR = 5.74), Quechua- (OR = 11.08, OR = 9.89), and Peru Spanish-speaking women (OR = 17.25, 14.43) were significantly more likely to be embarrassed and afraid, respectively, to get a Pap test compared with US non-Spanish-speaking women. US Spanish- (OR = 0.11), Quechua- (OR = 0.14), and Peru Spanish-speaking women (OR = 0.11) women were significantly less likely to know the HPV vaccine is safe and effective compared with US non-Spanish-speaking women. Education must be implemented to address serious misconceptions and worrisome attitudes toward Pap tests and the HPV vaccine to decrease the rate of cervical cancer in Peru and US Spanish-speaking women.

    Many industrialized countries have introduced human papillomavirus (HPV) vaccination of young women, but vaccine uptake often remains suboptimal. This study aimed to investigate whether a social media site like Facebook is an appropriate tool to assess knowledge, attitude and uptake related to HPV vaccination in young women in Germany. Between December 2012 and January 2013 two different targeting strategies were implemented on Facebook, providing a link to an online questionnaire. Advertisements were displayed to female Facebook users aged 18-25 years living in Germany. During the simple targeting strategy, advertisements comprised health-related images along with various short titles and text messages. During the focused strategy, advertisements were targeted to users who in addition had certain fashion brands or pop stars listed on their profiles. The targeting strategies were compared with respect to participant characteristics. Univariate and multivariate analyses were used to identify factors associated with HPV vaccine uptake. A total of 1161 women participated. The two targeting strategies resulted in significant differences regarding educational status and migrant background. Overall, awareness of HPV was high, but only 53% received at least one vaccine dose. In multivariate analysis, HPV vaccine uptake was independently associated with a physician's recommendation and trust in vaccine effectiveness. Concerns of adverse effects were negatively associated with vaccine uptake. Social network recruitment permits fast and convenient access to young people. Sample characteristics can be manipulated by adjusting targeting strategies. There is further need for promoting knowledge of HPV vaccination among young women. Physicians have a major role in the vaccination decision-making process of young women.

    For centuries, biology has provided fertile ground for hypothesis, discovery, and inspiration. Time-tested methods used in nature are being used as a basis for several research studies conducted at the NASA Langley Research Center as a part of Morphing Project, which develops and assesses breakthrough vehicle technologies. These studies range from low drag airfoil design guided by marine and avian morphologies to soaring techniques inspired by birds and the study of small flexible wing vehicles. Biology often suggests unconventional yet effective approaches such as non-planar wings, dynamic soaring, exploiting aeroelastic effects, collaborative control, flapping, and fibrous active materials. These approaches and other novel technologies for future flight vehicles are being studied in NASA's Morphing Project. This paper will discuss recent findings in the aeronautics-based, biologically-inspired research in the project.

    The purpose of this study was to evaluate the awareness of human papillomavirus (HPV) infections both in male and female adults in Hungary. A self-administered, anonymous questionnaire was completed by 785 college students and parents between January and May, 2009. The results were analysed by gender and age. Participants' knowledge about HPV and HPV-associated conditions was relatively incomplete. One-third of the respondents had never heard about HPV prior to the survey. Almost half of the respondents (42%) thought that the only sexual way of spreading HPV was vaginal intercourse, while the role of skin-to-skin contact was disregarded (6%). More than one-third of the participants (38%) believed that condoms give full protection from HPV infection. Encouragingly, the majority of respondents (64%) were open to further information about sexually transmitted diseases. The most trusted sources of information were health professionals. When talking about children, parents attributed the major role in delivering information about sexually transmitted diseases to schools. Primary prevention through carefully planned educational programmes may further raise the awareness about HPV-associated conditions, thus reducing the comparatively high mortality of cervical carcinoma in Hungary. © 2011 Blackwell Publishing Ltd.

    2013-07-12

    Proteins are the functional components of many cellular processes and the identification of their physical protein–protein interactions (PPIs) is an area of mature academic research. Various databases have been developed containing information about experimentally and computationally detected human PPIs as well as their corresponding annotation data. However, these databases contain many false positive interactions, are partial and only a few of them incorporate data from various sources. To overcome these limitations, we have developed HINT-KB (http://biotools.ceid.upatras.gr/hint-kb/), a knowledge base that integrates data from various sources, provides a user-friendly interface for their retrieval, cal-culatesasetoffeaturesofinterest and computesaconfidence score for every candidate protein interaction. This confidence score is essential for filtering the false positive interactions which are present in existing databases, predicting new protein interactions and measuring the frequency of each true protein interaction. For this reason, a novel machine learning hybrid methodology, called (Evolutionary Kalman Mathematical Modelling—EvoKalMaModel), was used to achieve an accurate and interpretable scoring methodology. The experimental results indicated that the proposed scoring scheme outperforms existing computational methods for the prediction of PPIs.

    Through evolution, nature came up with many effective solutions to its challenges and continually improving them. By mimicking, coping and being inspired, humans have been using Nature's solutions to address their own challenges. In recent years, the implementation of nature's capabilities has intensified with our growing understanding of the various biological and nastic mechanisms and processes. Successes include even the making of humanlike robots that perform such lifelike tasks as walking, talking, making eye-contact, interpreting speech and facial expressions, as well as many other humanlike functions. Generally, once humans are able to implement a function then, thru rapid advances in technology, capabilities are developed that can significantly exceed the original source of inspiration in Nature. Examples include flight where there is no species that can fly as high, carry so much mass, has so large dimensions and fly so fast, and operate at as such extreme conditions as our aircraft and other aerospace systems. However, using the capabilities of today's technology, there are many challenges that are not feasible to address in mimicking characteristics of species and plants. In this manuscript, state-of-the-art of biomimetic capabilities, potentials and challenges are reviewed.

    Full Text Available This article seeks to explore what the inspired text of the Old Testament was as it existed for the New Testament authors, particularly for the author of the book of Hebrews. A quick look at the facts makes. it clear that there was, at the time, more than one 'inspired' text, among these were the Septuagint and the Masoretic Text 'to name but two'. The latter eventually gained ascendancy which is why it forms the basis of our translated Old Testament today. Yet we have to ask: what do we make of that other text that was the inspired Bible to the early Church, especially to the writer of the book of Hebrews, who ignored the Masoretic text? This article will take a brief look at some suggestions for a doctrine of inspiration that keeps up with the facts of Scripture. Allied to this, the article is something of a bibliographical study of recent developments in textual research following the discovery of the Dead Sea scrolls.

    Study Aim: The aim of this investigation was to assess awareness and knowledge of HPV and HPV vaccination in a sample of female and male students from Fulda. Further vaccination uptake was investigated. Methods: In 2011 a regional cross-sectional survey of 13- to 21-year-old students (n=1 515) was conducted by using a standardised questionnaire. Results: Overall, the awareness and knowledge of human papillomavirus (HPV) was poor. 29% of the sample had heard of HPV. Multivariate analyses demonstrate that females as well as Christians knew HPV better than males and Muslims. Mean HPV knowledge score was 7.8 of 21 (SD=3.3). None of the tested sociodemographic variables was a predictor for better HPV knowledge. 77% of the sample was aware of the HPV vaccination. Females, persons without migration background as well as persons with middle or higher education knew HPV vaccination better than males, persons with migration background and lower educational level. Mean HPV vaccination knowledge score of the female students was 2.9 of 5 (SD=1.3). Older female students had a better level of knowledge than younger ones. 30% of the females had received at least one dose. Higher age, no migration background and middle or higher education status were tested as significant predictors of vaccine uptake. Conclusion: School lessons and consultations would be appropriate places to transfer knowledge in order to prevent health inequalities caused by social determinants. © Georg Thieme Verlag KG Stuttgart · New York.

  18. Optimal Design of a Bio-Inspired Anthropocentric Shoulder Rehabilitator

    S. K. Mustafa

    2006-01-01

    Full Text Available This paper presents the design of a bio-inspired anthropocentric 7-DOF wearable robotic arm for the purpose of stroke rehabilitation. The proposed arm rehabilitator synergistically utilizes the human arm structure with non-invasive kinematically under-deterministic cable-driven mechanisms to form a completely deterministic structure. It offers the advantages of being lightweight and having high dexterity. Adopting an anthropocentric design concept also allows it to conform to the human anatomical structure. The focus of this paper is on the analysis and design of the 3-DOF-shoulder module, called the shoulder rehabilitator. The design methodology is divided into three main steps: (1 performance evaluation of the cable-driven shoulder rehabilitator, (2 performance requirements of the shoulder joint based on its physiological characteristics and (3 design optimization of the shoulder rehabilitator based on shoulder joint physiological limitations. The aim is to determine a suitable configuration for the development of a shoulder rehabilitator prototype.

    2017-08-01

    Objective: To review the developments in human factors (HF) research on the challenges of health information technology (HIT) implementation and impact given the continuing incidence of usability problems and unintended consequences from HIT development and use. Methods: A search of PubMed/Medline and Web of Science® identified HF research published in 2015 and 2016. Electronic health records (EHRs) and patient-centred HIT emerged as significant foci of recent HF research. The authors selected prominent papers highlighting ongoing HF and usability challenges in these areas. This selective rather than systematic review of recent HF research highlights these key challenges and reflects on their implications on the future impact of HF research on HIT. Results: Research provides evidence of continued poor design, implementation, and usability of HIT, as well as technology-induced errors and unintended consequences. The paper highlights support for: (i) strengthening the evidence base on the benefits of HF approaches; (ii) improving knowledge translation in the implementation of HF approaches during HIT design, implementation, and evaluation; (iii) increasing transparency, governance, and enforcement of HF best practices at all stages of the HIT system development life cycle. Discussion and Conclusion: HF and usability approaches are yet to become embedded as integral components of HIT development, implementation, and impact assessment. As HIT becomes ever-more pervasive including with patients as end-users, there is a need to expand our conceptualisation of the problems to be addressed and the suite of tactics and strategies to be used to calibrate our pro-active involvement in its improvement.

    Full Text Available Background & Objective: The immune system of Patients with Acquired Immune Deficiency Syndrome (AIDS is weekend because of Human immunodeficiency virus (HIV infection, and they become vulnerable to several opportunistic and non-opportunistic pathogens and different carcinomas. IV drug abuse, sexual contact, occupational transmission, blood transfusion and maternal-fetal transmission are well known transmission routes for HIV infection. This study was under taken to investigate the prevalence of HIV transmission routs in the HIV infected population of Sirjan, and their knowledge about the disease, in order to plan better preventive strategies. Materials & Methods: A cross sectional study was planned. During a 6-month period in 2010, all of the HIV infected people in Sirjan (old and new cases who had a file at the consultation center for high risk behavior, completed a valid and reliable questionnaire. Results: The definite route of transmission was not clear in any of the patients because they had more than one suspicious route. Injected drug abusers were the most common (88.4% followed by those who got tattoos (79.1%, invasive therapeutic procedures, dentistry, surgery and endoscopy (56.1%, high risk sexual behavior (62.8%, bloodletting (9.3%, injuries in the barbershop (9.3% and blood transfusion (2.3%. Conclusion: All of the HIV infected cases in Sirjan were involved with several high risk behaviors, but the major route of transmission, similar to other parts of the country was injected drug abuse. Educational programs for prevention of AIDS should be followed seriously and special attention should be paid to groups with multiple high risk behaviors.

    Cervical cancer is the fourth most common cancer among women worldwide. Studies evaluating the effect of health education on knowledge and perception of cervical cancer have generated conflicting results. Thus, this study aimed to evaluate the effect of educational intervention towards knowledge of HPV vacccination for cervical cancer prevention among pre-university students in Malaysia. This was an experimental before and after study performed between October 2014 and March 2015. Five hundred and eighty students were randomly assigned into intervention and control groups. All were required to complete both pre-intervention and post-intervention questionnaires. Those in the intervention group were given an information leaflet to read before answering the post-intervention questionnaire. Almost half (48.3%) of the students had poor knowledge, with a score less than 5, and only 51 (8.8%) exhibited good knowledge, with a score of 11 and above. After educational intervention, the number of students with poor knowledge was reduced to 177 (29.3%) and the number of students who exhibited good knowledge increased to 148 (25.5%). Students from the intervention group demonstrated significant higher total scores in knowledge regarding 'HPV infection and cervical cancer' (p=0.000) and 'HPV vaccination and cervical cancer prevention' (p=0.000) during post-intervention as compared to the control group. Knowledge on HPV infection and vaccination is low among pre-university students. Educational intervention in the form of information leaflets appears effective in creating awareness and improving knowledge.

    Knowledge translation (KT) is a buzzword in modern medical science. However, there has been little theoretical reflection on translation as a process of meaning production in KT. In this paper, we argue that KT will benefit from the incorporation of a more theoretical notion of translation as an entangled material, textual and cultural process. We discuss and challenge fundamental assumptions in KT, drawing on theories of translation from the human sciences. We show that the current construal of KT as separate from and secondary to the original scientific message is close to the now deeply compromised literary view of translation as the simple act of copying the original. Inspired by recent theories of translation, we claim that KT can be more adequately understood in terms of a 'double supplement' - on the one hand, KT offers new approaches to the communication of scientific knowledge to different groups in the healthcare system with the aim of supplementing a lack of knowledge among clinicians (and patients). On the other, it demonstrates that a textual and cultural supplement, namely a concern with target audiences (clinicians and patients), is inevitable in the creation of an 'autonomous' science. Hence, the division between science and its translation is unproductive and impossible to maintain. We discuss some possible implications of our suggested shift in concept by drawing on pharmaceutical interventions for the prevention of HIV as a case. We argue that such interventions are based on a supplementary and paradoxical relation to the target audiences, both presupposing and denying their existence. More sophisticated theories of translation can lay the foundation for an expanded model of KT that incorporates a more adequate and reflective description of the interdependency of scientific, cultural, textual and material practices.

    Climate change and ocean acidification are likely to have a profound effect on marine molluscs, which are of great ecological and economic importance. One process particularly sensitive to climate change is the formation of biominerals in mollusc shells. Fundamental research is broadening our understanding of the biomineralization process, as well as providing more informed predictions on the effects of climate change on marine molluscs. Such studies are important in their own right, but their value also extends to applied sciences. Biominerals, organic/inorganic hybrid materials with many remarkable physical and chemical properties, have been studied for decades, and the possibilities for future improved use of such materials for society are widely recognised. This article highlights the potential use of our understanding of the shell biomineralization process in novel bio-inspired and biomimetic applications. It also highlights the potential for the valorisation of shells produced as a by-product of the aquaculture industry. Studying shells and the formation of biominerals will inspire novel functional hybrid materials. It may also provide sustainable, ecologically- and economically-viable solutions to some of the problems created by current human resource exploitation. Copyright © 2016 Elsevier B.V.

    2014-10-01

    Full Text Available At Waseda University, since 1990, the authors have been developing anthropomorphic musical performance robots as a means for understanding human control, introducing novel ways of interaction between musical partners and robots, and proposing applications for humanoid robots. In this paper, the design of a biologically-inspired control architecture for both an anthropomorphic flutist robot and a saxophone playing robot are described. As for the flutist robot, the authors have focused on implementing an auditory feedback system to improve the calibration procedure for the robot in order to play all the notes correctly during a performance. In particular, the proposed auditory feedback system is composed of three main modules: an Expressive Music Generator, a Feed Forward Air Pressure Control System and a Pitch Evaluation System. As for the saxophone-playing robot, a pressure-pitch controller (based on the feedback error learning to improve the sound produced by the robot during a musical performance was proposed and implemented. In both cases studied, a set of experiments are described to verify the improvements achieved while considering biologically-inspired control approaches.

    Inorganic semiconductors permeate virtually every sphere of modern human existence. Micro-fabricated memory elements, processors, sensors, circuit elements, lasers, displays, detectors, etc are ubiquitous. However, the dawn of the 21st century has brought with it immense new challenges, and indeed opportunities—some of which require a paradigm shift in the way we think about resource use and disposal, which in turn directly impacts our ongoing relationship with inorganic semiconductors such as silicon and gallium arsenide. Furthermore, advances in fields such as nano-medicine and bioelectronics, and the impending revolution of the ‘ubiquitous sensor network’, all require new functional materials which are bio-compatible, cheap, have minimal embedded manufacturing energy plus extremely low power consumption, and are mechanically robust and flexible for integration with tissues, building structures, fabrics and all manner of hosts. In this short review article we summarize current progress in creating materials with such properties. We focus primarily on organic and bio-organic electronic and optoelectronic systems derived from or inspired by nature, and outline the complex charge transport and photo-physics which control their behaviour. We also introduce the concept of electrical devices based upon ion or proton flow (‘ionics and protonics’) and focus particularly on their role as a signal interface with biological systems. Finally, we highlight recent advances in creating working devices, some of which have bio-inspired architectures, and summarize the current issues, challenges and potential solutions. This is a rich new playground for the modern materials physicist.

    2015-07-01

    Full Text Available We present a review of the etymology of zoological taxonomic names with emphasis on the most unusual examples. The names were divided into several categories, starting from the most common – given after morphological features – through inspiration from mythology, legends, and classic literature but also from fictional and nonfictional pop-culture characters (e.g., music, movies or cartoons, science, and politics. A separate category includes zoological names created using word-play and figures of speech such as tautonyms, acronyms, anagrams, and palindromes. Our intention was to give an overview of possibilities of how and where taxonomists can find the inspirations that will be consistent with the ICZN rules and generate more detail afterthought about the naming process itself, the meaningful character of naming, as well as the recognition and understanding of names.

    2013-01-01

    Biologically inspired systems based on cellular mechanics demonstrate the ability to selectively transport ions across a bilayer membrane. These systems may be observed in nature in plant roots, which remove select nutrients from the surrounding soil against significant concentration gradients. Using biomimetic principles in the design of tailored active materials allows for the development of selective membranes for capturing and filtering targeted ions. Combining this biomimetic transport system with a method for reclaiming the captured ions will allow for increased removal potential. To illustrate this concept, a device for removing nutrients from waterways to aid in reducing eutrophication is outlined and discussed. Presented is a feasibility study of various cellular configurations designed for this purpose, focusing on maximizing nutrient uptake. The results enable a better understanding of the benefits and obstacles when developing these cellularly inspired systems. (paper)

    Teenager sexuality is a public health issue. In teenagers attending a high school, we assessed their knowledge and behavior on sexuality, infectious transmitted diseases, human papilloma virus (HPV) vaccination, and cervical cancer. Then in girls, we estimated the anti-HPV vaccination coverage and focused on factors associated with poor knowledge of these topics. This was a knowledge, attitudes, and practices cross-sectional study conducted at the beginning of the 2010-2011 school year in the Saint-Cyr military high school, using an anonymous self-administered questionnaire. Among 669 adolescents (M/F sex-ratio, 2.3; mean age, 17 years [IC 95%, 15-20]), 40% had already had sex and 92% had used contraception. Boys and girls had a poor level of knowledge on infectious transmitted diseases. Regarding knowledge on HPV and cervical cancer, a better level was significantly associated with female gender (P=10(-4)). In multivariate analysis, male gender, age under 18 years, lack of dialogue with parents on these subjects, low socioeconomic status of parents, and absence of health education were significantly associated with poor knowledge on these topics. These data should help healthcare providers better target access and content of sexual health education training. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Quantum-inspired computing is an emerging research area, which has significantly improved the capabilities of conventional algorithms. In general, quantum-inspired hopfield associative memory (QHAM) has demonstrated quantum information processing in neural structures. This has resulted in an exponential increase in storage capacity while explaining the extensive memory, and it has the potential to illustrate the dynamics of neurons in the human brain when viewed from quantum mechanics perspective although the application of QHAM is limited as an autoassociation. We introduce a quantum-inspired multidirectional associative memory (QMAM) with a one-shot learning model, and QMAM with a self-convergent iterative learning model (IQMAM) based on QHAM in this paper. The self-convergent iterative learning enables the network to progressively develop a resonance state, from inputs to outputs. The simulation experiments demonstrate the advantages of QMAM and IQMAM, especially the stability to recall reliability.

    Bio-Mimicking/Bio-Inspiration: How can we not be inspired by Nature? Life has evolved on earth over the last 3.5 to 4 billion years. Materials formed during this time were not toxic; they were created at low temperatures and low pressures unlike many of the materials developed today. The natural materials formed are self-assembled, multifunctional, nonlinear, complex, adaptive, self-repairing and biodegradable. The designs that failed are fossils. Those that survived are the success stories. Natural materials are mostly formed from organics, inorganic crystals and amorphous phases. The materials make economic sense by optimizing the design of the structures or systems to meet multiple needs. We constantly "see" many similar strategies in approaches, between man and nature, but we seldom look at the details of natures approaches. The power of image processing, in many of natures creatures, is a detail that is often overlooked. Seldon does the engineer interact with the biologist and learn what nature has to teach us. The variety and complexity of biological materials and the optical systems formed should inspire us.

    We propose to design a small-size transmission-coupled antenna array, and corresponding radiation pattern, having high performance inspired by the female Ormia ochracea's coupled ears. For reproduction purposes, the female Ormia is able to locate male crickets' call accurately despite the small distance between its ears compared with the incoming wavelength. This phenomenon has been explained by the mechanical coupling between the Ormia's ears, which has been modeled by a pair of differential equations. In this paper, we first solve these differential equations governing the Ormia ochracea's ear response, and convert the response to the pre-specified radio frequencies. We then apply the converted response of the biological coupling in the array factor of a uniform linear array composed of finite-length dipole antennas, and also include the undesired electromagnetic coupling due to the proximity of the elements. Moreover, we propose an algorithm to optimally choose the biologically inspired coupling for maximum array performance. In our numerical examples, we compute the radiation intensity of the designed system for binomial and uniform ordinary end-fire arrays, and demonstrate the improvement in the half-power beamwidth, sidelobe suppression and directivity of the radiation pattern due to the biologically inspired coupling.

    2016-01-01

    This book investigates a biologically inspired method of robot arm control, developed with the objective of synthesising human-like motion dynamically, using nonlinear, robust and adaptive control techniques in practical robot systems. The control method caters to a rising interest in humanoid robots and the need for appropriate control schemes to match these systems. Unlike the classic kinematic schemes used in industrial manipulators, the dynamic approaches proposed here promote human-like motion with better exploitation of the robot’s physical structure. This also benefits human-robot interaction. The control schemes proposed in this book are inspired by a wealth of human-motion literature that indicates the drivers of motion to be dynamic, model-based and optimal. Such considerations lend themselves nicely to achievement via nonlinear control techniques without the necessity for extensive and complex biological models. The operational-space method of robot control forms the basis of many of the techniqu...

    Oral health care of patients with human immunodeficiency virus (HIV)/acquired immune-deficiency syndrome (AIDS) is a growing area of concern. Information on HIV- and AIDS-related knowledge among dental students provides a crucial foundation for efforts aimed at developing an appropriate dental curriculum on HIV and AIDS. The purpose of this study was to assess the knowledge and attitude of Indian clinical dental students towards the treatment of patients with HIV/AIDS and perceived sources of information regarding HIV-related issues. Data were collected from clinical dental students (third year, fourth year and internship) from three dental institutions in Delhi National Capital Region (NCR). The questions assessed the knowledge and attitude towards treatment of patients with HIV and the perceived source of information related to HIV. The willingness to treat HIV-positive patients among dental students was 67.0%, and 74.20% were confident of treating a patient with HIV/AIDS. The potential problems in rendering treatment to these patients were effect on the attitude of other patients (49.90%) and staff fears (52.50%). The correct knowledge regarding the infection-control practice (barrier technique) was found among only 15.50% of respondents. The respondents had sufficient knowledge regarding the oral manifestations of HIV/AIDS. There was no correlation between the knowledge and attitude score, demonstrating a gap between knowledge and attitude among dental students regarding treatment of HIV-infected patients. Appropriate knowledge has to be delivered through the dental education curriculum, which can instil confidence in students about their ability to manage HIV-positive patients. © 2014 FDI World Dental Federation.

    Full Text Available Abstract Background Genital Human papilloma virus (HPV is one of the most commonly diagnosed Sexually Transmitted Infection (STIs in men and women. Knowledge about HPV infection among men is limited. This study aims to determine correlates of adequate knowledge of HPV infection among men who attend an STI clinic in Puerto Rico. Methods A cross-sectional study of 206 men was conducted at an STI clinic in San Juan, PR. Adequate knowledge was defined as a score of at least 70% of correct responses among those men who reported having ever heard of HPV. Variables that achieved statistical significance in the bivariate analysis (p Results Although 52.5% of men reported having heard of HPV infection before the survey, only 29.3% of this sub-group had an adequate knowledge of HPV. Most men did not know that HPV is a risk factor for anal (38.7%, penile (50.0% and oral (72.6% cancer. Factors associated with adequate knowledge of HPV in age-adjusted models were being men who have sex with men (MSM (OR=2.6;95%CI=1.1-6.1, self-report of genital warts (OR=3.2;95%CI=1.3-7.9 and herpes (OR=7.4;95% CI=2.2-25.1. MSM was marginally associated with adequate knowledge (OR=2.3;95% CI=0.9-5.9 and self-report of herpes remained significantly associated (OR=5.0;95%CI=1.3-18.4 in multivariate logistic regression analysis. Conclusions Awareness and knowledge of HPV was very low in this group of men. Interventions to increase knowledge and awareness in this group are necessary to promote preventive practices for HPV-related cancers in high-risk groups.

    The concept of eco-cultural health considers the dynamic interaction between humans and ecosystems, emphasizing the implications of the health of the ecosystem for the health and well-being of human populations. Ethnobotanical studies focusing on folk medicine and medicinal plants can contribute to the field of eco-cultural health if they incorporate the perspective and local knowledge of communities. We investigated the local health practices in three rural communities living within the vicinity of a protected area of sustainable use in a semi-arid region of Brazil. We analyzed the opinions of local health experts on the elements that influence human health and on how the environment contributes to this influence. We also analyzed and compared the local knowledge of medicinal plants, as knowledge of this type is an important factor when considering the interaction between environmental and human health. We performed structured interviews and free-listings with 66 local health experts. We used content analysis to systematize the elements of the influences on human health. We compared the richness of the plants cited among communities and analyzed the differences among the three communities regarding the ways in which the plants were obtained and the environments in which plants were collected. The local experts identified several influences of the environment on human health. These influences can be associated with ecosystem services, such as climatic conditions, water and air quality, recreation and medicinal and food resources. We identified 192 medicinal plant species, most of which were gathered from wild ecosystems. The most important environments for the three communities were the plateau mountain and backyards. The informants had a broad and integrated view of health, perceiving the importance of conserving the environment within the National Forest of Araripe for the health and well-being of the local populations.

  12. Feeling Is Believing: Inspiration Encourages Belief in God.

    Critcher, Clayton R; Lee, Chan Jean

    2018-05-01

    Even without direct evidence of God's existence, about half of the world's population believes in God. Although previous research has found that people arrive at such beliefs intuitively instead of analytically, relatively little research has aimed to understand what experiences encourage or legitimate theistic belief systems. Using cross-cultural correlational and experimental methods, we investigated whether the experience of inspiration encourages a belief in God. Participants who dispositionally experience more inspiration, were randomly assigned to relive or have an inspirational experience, or reported such experiences to be more inspirational all showed stronger belief in God. These effects were specific to inspiration (instead of adjacent affective experiences) and a belief in God (instead of other empirically unverifiable claims). Being inspired by someone or something (but not inspired to do something) offers a spiritually transcendent experience that elevates belief in God, in part because it makes people feel connected to something beyond themselves.

    The purpose of the study is to investigate knowledge, attitudes and behaviours concerning cervical cancer, HPV and HPV vaccine of female students studying at a university in a health related department and explore variables affecting taking the vaccine. The research group consists of female students attending a health related department in Balıkesir University. The data of this cross-sectional research was collected via surveys. The average total knowledge score of the students concerning risks, symptoms and screening methods of cervical cancer and HPV vaccines was 14.15 ± 6.7. The HPV knowledge score of the students attending the faculty of medicine was higher compared to the students attending other departments and their HPV vaccine knowledge score was higher compared to the students attending nursing and paramedics students. The HPV vaccine knowledge score of the students attending the department of midwifery was significantly higher compared to other students. Only 0.9 % of the students took the vaccine. One third of the students who did not take the vaccine did not know that the vaccine was available in our country. In terms of the department that they attended, the students with a higher total knowledge score compared to the average (OR:1.5) and students with history of cancer in their families (OR:1.6) were more likely to consider taking the vaccine. Research group's knowledge on risk factors of cervical cancer, Pap smear test, symptoms and prevention ways of cancer, HPV and HPV vaccine was low.

    Wireless (virtual) synapses represent a novel approach to bio-inspired neural networks that follow the infrastructure of the biological brain, except that biological (physical) synapses are replaced by virtual ones based on cellular telephony modeling. Such synapses are of two types: intracluster synapses are based on IR wireless ones, while intercluster synapses are based on RF wireless ones. Such synapses have three unique features, atypical of conventional artificial ones: very high parallelism (close to that of the human brain), very high reconfigurability (easy to kill and to create), and very high plasticity (easy to modify or upgrade). In this paper we analyze the general concept of wireless synapses with special emphasis on RF wireless synapses. Also, biological mammalian (vertebrate) neural models are discussed for comparison, and a novel neural lensing effect is discussed in detail.

    Online educational resources, such as MOOCs, is becoming increasingly popular, especially in higher education field. One most important media type for MOOCs is course video. Besides traditional bottom-position subtitle accompany to the videos, in recent years, researchers try to develop more advanced algorithms to generate speaker-following style subtitles. However, the effectiveness of such subtitle is still unclear. In this paper, we investigate the relationship between subtitle position and the learning effect after watching the video on tablet devices. Inspired with image based human eye tracking technique, this work combines the objective gaze estimation statistics with subjective user study to achieve a convincing conclusion - speaker-following subtitles are more suitable for online educational videos.

    To determine the impact of human papilloma virus (HPV) vaccination on knowledge, perception of sexual risk and need for continued safe sexual behavior among Indonesian girls. A comparative cross-sectional study was carried on in Denpasar, the capital city of Bali, Indonesia, during September 2015-February 2016. A total of 828 adolescent girls (12-16 years) were recruited to assess their knowledge on HPV/HPV vaccine, perception of sexual risks and need for continued safe sexual behavior. A total of 419 girls (50.7%) had received HPV vaccination prior to the study, 76.4% of whom (320/419) had sufficient knowledge about HPV. HPV vaccination was a strong and independent predictor of higher HPV/HPV vaccine knowledge (adjusted OR [AOR], 9.358; 95%CI: 6.816-12.849, P < 0.001). HPV vaccination (AOR, 0.107; 95%CI: 0.074-0.155, P < 0.001) and higher knowledge level (AOR, 0.667; 95%CI: 0.464-0.958, P = 0.028) were associated with lower perceived HPV risk. Despite the low risk perception, most of the vaccinated girls (408/419, 97.4%) continued to perceive higher need for safe sexual behaviors. On multivariate analysis, higher knowledge was the independent predictor for higher perceived need for safe sexual behaviors (AOR, 4.260; 95%CI: 2.016-9.001, P < 0.001). The HPV vaccination was associated with higher knowledge and appropriately lower perception of HPV risk. Despite the vaccination, most of the adolescents continued to perceive a need for safer sexual behavior. All adolescent girls should receive HPV vaccination in order to reduce cervical cancer burden in the future. © 2016 Japan Society of Obstetrics and Gynecology.

    To elicit information about parents' knowledge, attitudes, and acceptability toward HPV infection and vaccination of male adolescents in Italy; to identify subgroups of this population who exhibit poor knowledge about prevention of HPV infection and reveal negative attitudes toward HPV vaccination in relation to their male sons. Data were collected via self-administered anonymous questionnaire from 1021 parents of males aged 10 to 14 y who were recruited from a random sample of public secondary schools in the South of Italy. Three-quarters (72.6%) reported that the vaccine is a preventive measure for HPV infection and 55.8% that condom use reduces the risk of HPV infection. A high education level, abundant sources of information about HPV infection received from physicians, and knowledge about HPV infection were factors significantly associated with high level of knowledge about preventive measures for HPV infection. 71% revealed their intentions to vaccinate their sons, and this intention was significantly associated with perceived benefits both for HPV vaccination for girls and for childhood recommended vaccinations as well as a need for additional information about HPV vaccination. 53.7% of the eligible parents reported that their daughters had been vaccinated against HPV. Results of the study suggest that the risk of acquiring HPV infection and HPV-related diseases is sorely underestimated. Knowledge on the benefits of adolescents' HPV vaccination in cancer prevention in both sexes should be improved to maximize uptake of HPV vaccination.

    In all the living organisms, the self-preservation behaviour is almost universal. Even the most simple of living organisms, like slime mould, is typically under intense selective pressure to evolve a response to ensure their evolution and safety in the best possible way. On the other hand, evacuation of a place can be easily characterized as one of the most stressful situations for the individuals taking part on it. Taking inspiration from the slime mould behaviour, we are introducing a computational bio-inspired model crowd evacuation model. Cellular Automata (CA) were selected as a fully parallel advanced computation tool able to mimic the Physarum's behaviour. In particular, the proposed CA model takes into account while mimicking the Physarum foraging process, the food diffusion, the organism's growth, the creation of tubes for each organism, the selection of optimum tube for each human in correspondence to the crowd evacuation under study and finally, the movement of all humans at each time step towards near exit. To test the model's efficiency and robustness, several simulation scenarios were proposed both in virtual and real-life indoor environments (namely, the first floor of office building B of the Department of Electrical and Computer Engineering of Democritus University of Thrace). The proposed model is further evaluated in a purely quantitative way by comparing the simulation results with the corresponding ones from the bibliography taken by real data. The examined fundamental diagrams of velocity-density and flow-density are found in full agreement with many of the already published corresponding results proving the adequacy, the fitness and the resulting dynamics of the model. Finally, several real Physarum experiments were conducted in an archetype of the aforementioned real-life environment proving at last that the proposed model succeeded in reproducing sufficiently the Physarum's recorded behaviour derived from observation of the aforementioned

    2012-01-01

    The antennules of many marine crustaceans enable them to rapidly locate sources of odorant in turbulent environmental flows and may provide biological inspiration for engineered plume sampling systems. A substantial gap in knowledge concerns how the physical interaction between a sensing device and the chemical filaments forming a turbulent plume affects odorant detection and filters the information content of the plume. We modeled biological arrays of chemosensory hairs as infinite arrays of odorant flux-detecting cylinders and simulated the fluid flow around and odorant flux into the hair-like sensors as they intercepted a single odorant filament. As array geometry and sampling kinematics were varied, we quantified distortion of the flux time series relative to the spatial shape of the original odorant filament as well as flux metrics that may be important to both organisms and engineered systems attempting to measure plume structure and/or identify chemical composition. The most important predictor of signal distortion is the ratio of sensor diameter to odorant filament width. Achieving high peak properties (e.g. sharpness) of the flux time series and maximizing the total number of odorant molecules detected appear to be mutually exclusive design goals. Sensor arrays inspired specifically by the spiny lobster Panulirus argus and mantis shrimp Gonodactylaceus falcatus introduce little signal distortion but these species' neural systems may not be able to resolve plume structure at the level of individual filaments via temporal properties of the odorant flux. Current chemical sensors are similarly constrained. Our results suggest either that the spatial distribution of flux across the aesthetasc array is utilized by P. argus and G. falcatus, or that such high spatiotemporal resolution is unnecessary for effective plume tracking.

    Batoids, or rays, utilize unique forms of locomotion that may offer more efficient techniques of motorized propulsion in various marine environments. We present a novel biomimetic engineering design and assembly of a stingray-inspired robot swimmer. The robots locomotion mimics the Dasyatis americana, or southern stingray, whose distinction among rays is its intermediate motion, characterized by sweeping strokes that propagate between 1/2-1 wavelength of the fin profile in the posterior direction. Though oscillatory ( wavelengths) ray-based robots have been created, this project demonstrates new engineering possibilities in what is, to the best of our knowledge, the first intermediately propelled batoid-based robot. The robots fins were made of silicone rubber, cast in a 3-D printed mold, with wingspan of 42 cm (1/2 - 1/5 scale for males and females, respectively, scale of model organism). Two anteriorly placed servomotors per fin were used, all controlled by one wirelessly enabled Arduino microcontroller. Each servomotor oscillated a flexible rod with cylindrical joint, whose frequency, speed, and front-back phase delay were user-programmed over wireless connection. During free-swimming tests, the fin profile developed about 0.8 wavelength, qualifying for successful mimicry of its biological inspiration. The robot satisfactorily maintained straight-line motion, reaching average peak velocity of 9.4+/-1.0 cm/s (0.27-0.03 body lengths/second) at its optimum flapping frequency of 1.4 Hz. This is in the same order of magnitude of speed normalized to body length achieved by others in two recent batoid-based projects. In summary, our robot performed intermediate stingray locomotion with relatively fewer components, which reveals robust potential for innovation of the simple intermediate batoid-based robot swimmer.

    Lateral Inhibition (LI) is a widely conserved patterning mechanism in biological systems across species. Distinct from better-known Turing patterns, LI depend on cell-cell contact rather than diffusion. We built an in silico genetic circuit model to analyze the dynamic properties of LI. The model revealed that LI amplifies differences between neighboring cells to push them into opposite states, hence forming stable 2-D patterns. Inspired by this insight, we designed and implemented an electronic circuit that recapitulates LI patterning dynamics. This biomimetic system serve as a physical model to elucidate the design principle of generating robust patterning through spatial feedback, regardless of the underlying devices being biological or electrical.

    The extensive scaling and integration within electronic systems have set the standards for what is addressed to as stochastic electronics. The individual components are increasingly diverting away from their reliable behavior and producing un-deterministic outputs. This stochastic operation highly mimics the biological medium within the brain. Hence, building on the inherent variability, particularly within novel non-volatile memory technologies, paves the way for unconventional neuromorphic designs. Neuro-inspired networks with brain-like structures of neurons and synapses allow for computations and levels of learning for diverse recognition tasks and applications.

    Bangladesh is one of the countries most vulnerable to climate change (CC). A basic understanding of public perception on vulnerability, attitude and the risk in relation to CC and health will provide strategic directions for government policy, adaptation strategies and development of community-based guidelines. The objective of this study was to collect community-based data on peoples' knowledge and perception about CC and its impact on health. In 2012, a cross-sectional survey was undertaken among 6720 households of 224 enumeration areas of rural villages geographically distributed in seven vulnerable districts of Bangladesh, with total population of 19,228,598. Thirty households were selected randomly from each enumeration area using the household listing provided by the Bangladesh Bureau of Statistics (BBS). Information was collected from all the 6720 research participants using a structured questionnaire. An observation checklist was used by the interviewers to collect household- and community-related information. In addition, we selected the head of each household as the eligible participant for an interview. Evidence of association between sociodemographic variables and knowledge of CC was explored by cross-tabulation and measured using chi-square tests. Logistic regression models were used to further explore the predictors of knowledge. The study revealed that the residents of the rural communities selected for this study largely come from a low socioeconomic background: only 9.6% had postsecondary education or higher, the majority worked as day labourer or farmer (60%), and only 10% earned a monthly income above BDT 12000 (equivalent to US $150 approx.). The majority of the participants (54.2%) had some knowledge about CC but 45.8% did not (p change of climate (83.2%). Among all the respondents (n = 6720), 94.5% perceived change in climate and extreme weather events. Most of them (91.9%) observed change in rainfall patterns in the last 10 years, and 97

    The Chain Experiment is an annual competition which originated in Slovenia in 2005 and later expanded to Poland in 2013. For the purpose of the event, each participating team designs and builds a contraption that transports a small steel ball from one end to the other. At the same time the constructed machine needs to use a number of interesting phenomena and physics laws. In the competition’s finale, all contraptions are connected to each other to form a long chain transporting steel balls. In brief, they are all evaluated for qualities such as: creativity and advance in theoretical background, as well as the reliability of the constructed machine to work without human help. In this article, we present the contraptions developed by students taking part in the competition in order to demonstrate the advance in theoretical basis together with creativity in design and outstanding engineering skills of its participants. Furthermore, we situate the Chain Experiment in the context of other group competitions, at the same time demonstrating that—besides activating numerous group work skills—it also improves the ability to think critically and present one’s knowledge to a broader audience. We discussed it in the context of problem based learning, gamification and collaborative testing.

    Full Text Available Introduction: India is estimated to have the third highest number of human immunodeficiency virus (HIV infections in the world with about 20.89 lakh people currently living with HIV/acquired immunodeficiency syndrome (AIDS. Inadequate knowledge, negative attitudes, and ignorance among the school students are major hindrances to prevent the spread of HIV. Aim: To assess the knowledge and attitude toward HIV/AIDS among the higher secondary school students of Jaipur city. Materials and Methods: A questionnaire-based cross-sectional study comprising 613 higher secondary school students (male = 390, female = 223 from Jaipur city were included in the study. The city was divided into 4 zones and one school from each zone was selected randomly. A questionnaire assessing the knowledge and attitude toward HIV/AIDS was distributed among the senior school students. Pilot study was done among 50 students to test the validity of the questionnaire. Results: All the students (100% in our sample knew what is AIDS. About 96.2% of the students knew that AIDS is not a simple disease, the correct knowledge about the modes of transmission of HIV/AIDS was nearly 85.6% and about 94% of students would not leave the school if there was an AIDS student in their class. Eighty-four percent of students believed that students with AIDS should not go to special schools and about 95.8% students believed that HIV individuals must be supported, treated, and helped. Conclusion: The students had satisfactory knowledge about HIV/AIDS and their attitude toward this group of people was good. There is need and opportunity to provide factual and precise knowledge on HIV/AIDS for school students. There should also be a drive to increase education and awareness about HIV/AIDS in educational institutes.

    The aim of this study was to ascertain farmers' knowledge of the risk of spread of infection from animals to humans, and their transmission prevention practices. This was a survey of farmers who submitted material to Ireland's Regional Veterinary Laboratories in 2015. There was an 84% response rate (1044 farmers). Ninety per cent of farmers were not aware that infection can be acquired from apparently healthy animals. Over half were not aware that disease could be contracted from sick poultry or pets. Conversely, the knowledge of the risk to pregnant women of infection from birthing animals was high (88%). Four-fifths of farmers sourced drinking water from a private well, and of these, 62% tested their water less frequently than once a year. Of dairy farmers, 39% drank unpasteurised milk once a week or more frequently. Veterinarians were the most commonly cited information source for diseases on farms. The survey findings indicate that the level of farmers' knowledge and awareness of the spread of infection from animals to humans is a concern. Further education of the farming community is needed to increase awareness of both the potential biohazards present on farms and the practical measures that can be taken to mitigate the risk of zoonoses.

    Full Text Available In this paper, I try to argue that both science, as a specific kind of knowledge, and human knowledge in general are activities of constructing models. In the first part, I present my conception according to which scientific models are abstract entities, and that scientific theories may be interpreted as classes of models as abstract replicas of real settings, in which certain laws apply. In the second part, I try to extend that same conception to ordinary human knowledge, particularly to the case of the cognitive activity of classifying objects of experience.Neste artigo, vamos procurar argumentar que tanto a ciência, enquanto um tipo específico de conhecimento, quanto o conhecimento humano em geral são atividades de construção de modelos. Na primeira parte, apresentamos nossa concepção segundo a qual os modelos científicos são entidades abstratas, e as teorias científicas podem ser interpretadas como classes de modelos enquanto réplicas abstratas de situações reais, nas quais valem determinadas leis. Na segunda parte, procuramos estender essa mesma concepção ao conhecimento humano ordinário, em particular, ao caso da atividade cognitiva de classificar os objetos da experiência.

    Full Text Available Abstract Background Bangladesh is one of the countries most vulnerable to climate change (CC. A basic understanding of public perception on vulnerability, attitude and the risk in relation to CC and health will provide strategic directions for government policy, adaptation strategies and development of community-based guidelines. The objective of this study was to collect community-based data on peoples’ knowledge and perception about CC and its impact on health. Methods In 2012, a cross-sectional survey was undertaken among 6720 households of 224 enumeration areas of rural villages geographically distributed in seven vulnerable districts of Bangladesh, with total population of 19,228,598. Thirty households were selected randomly from each enumeration area using the household listing provided by the Bangladesh Bureau of Statistics (BBS. Information was collected from all the 6720 research participants using a structured questionnaire. An observation checklist was used by the interviewers to collect household- and community-related information. In addition, we selected the head of each household as the eligible participant for an interview. Evidence of association between sociodemographic variables and knowledge of CC was explored by cross-tabulation and measured using chi-square tests. Logistic regression models were used to further explore the predictors of knowledge. Results The study revealed that the residents of the rural communities selected for this study largely come from a low socioeconomic background: only 9.6 % had postsecondary education or higher, the majority worked as day labourer or farmer (60 %, and only 10 % earned a monthly income above BDT 12000 (equivalent to US $150 approx.. The majority of the participants (54.2 % had some knowledge about CC but 45.8 % did not (p < 0.001. The majority of knowledgeable participants (n = 3645 felt excessive temperature as the change of climate (83.2 %. Among all the

    Inspired by nature, in particular by the marine mussels adhesive proteins (MAPs) and by the tough brick-and-mortar nacre-like structure, novel multilayered films are prepared in the present work. Organic-inorganic multilayered films, with an architecture similar to nacre based on bioactive glass nanoparticles (BG), chitosan, and hyaluronic acid modified with catechol groups, which are the main components responsible for the outstanding adhesion in MAPs, are developed for the first time. The biomimetic conjugate is prepared by carbodiimide chemistry and analyzed by ultraviolet-visible spectrophotometry. The buildup of the multilayered films is monitored with a quartz crystal microbalance with dissipation monitoring, and their topography is characterized by atomic force microscopy. The mechanical properties reveal that the films containing catechol groups and BG present an enhanced adhesion. Moreover, the bioactivity of the films upon immersion in a simulated body fluid solution is evaluated by scanning electron microscopy coupled with energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, and X-ray diffraction. It was found that the constructed films promote the formation of bonelike apatite in vitro. Such multifunctional mussel inspired LbL films, which combine enhanced adhesion and bioactivity, could be potentially used as coatings of a variety of implants for orthopedic applications.

    One of the approaches to building artificial intelligence (AI) is to decipher the princi- ples of the brain function and to employ similar mechanisms for solving cognitive tasks, such as visual perception or natural language understanding, using machines. The recent breakthrough, named deep learning, demonstrated that large multi-layer networks of arti- ficial neural-like computing units attain remarkable performance on some of these tasks. Nevertheless, such artificial networks remain to be very loosely inspired by the brain, which rich structures and mechanisms may further suggest new algorithms or even new paradigms of computation. In this thesis, we explore brain-inspired probabilistic mechanisms, such as neural and synaptic stochasticity, in the context of generative models. The two questions we ask here are: (i) what kind of models can describe a neural learning system built of stochastic components? and (ii) how can we implement such systems e ̆ciently? To give specific answers, we consider two well known models and the corresponding neural architectures: the Naive Bayes model implemented with a winner-take-all spiking neural network and the Boltzmann machine implemented in a spiking or non-spiking fashion. We propose and analyze an e ̆cient neuromorphic implementation of the stochastic neu- ral firing mechanism and study the e ̄ects of synaptic unreliability on learning generative energy-based models implemented with neural networks.

    There is a shortage of medical doctors in primary health care (PHC) settings in Vietnam. Evidence about the knowledge medical students have about PHC and their career decision-making is important for making policy in human resources for health. The objective of this study was to analyse knowledge and attitudes about PHC among medical students in their final year and their choice to work in PHC after graduation. A cross-sectional study was conducted among 400 final year general medical students from Hanoi Medical University. Self-administered interviews were conducted. Key variables were knowledge, awareness of the importance of PHC and PHC career choices. Descriptive and analytic statistics were performed. Students had essential knowledge of the concept and elements of PHC and were well aware of its importance. However, only one-third to one half of them valued PHC with regard to their professional development or management opportunities. Less than 1% of students would work at commune or district health facilities after graduation. This study evidences challenges related to increasing the number of medical doctors working in PHC settings. Immediate and effective interventions are needed to make PHC settings more attractive and to encourage medical graduates to start and continue a career in PHC.

    Full Text Available BACKGROUND Cervical cancer in women can be effectively prevented by HPV vaccine. Healthcare professionals including pharmacists have a role in creating awareness about this vaccine to public. In this context, it was decided to study awareness level about HPV among pharmacy students. The aim of the study is to study the knowledge and attitude towards human papilloma virus and it’s vaccine among pharmacy students of tertiary teaching university hospital in South India. MATERIALS AND METHODS Cross sectional, questionnaire-based study among pharmacy students. RESULTS 229 pharmacy students participated in the study. The mean total knowledge score among participants was 2.69 (SD=2.260 out of the possible maximum of 11 and the mean total attitude score was 2.67 (SD=2.437 out of the possible maximum of 10. Lack of knowledge about vaccine was the main reason for not taking the vaccine. Knowledge about the vaccines improves the attitude towards it (p<0.0001. CONCLUSION There is a need to design education program for pharmacy students to increase awareness about HPV, which in turn will increase the awareness among public positively.

  17. Does Ignorance Matter? The Relative Importance of Civic Knowledge and the Human Tendency to Engage in Motivated Reasoning

    Full Text Available It has long been understood that political knowledge in the U.S. is very low. For those who care about the quality of American democracy, this is a big problem. In attempting to find a solution, many people often blame education. While increasing civic knowledge is a laudatory goal, increased political sophistication does not necessarily turn individuals into good democratic citizens. Research in cognitive and social psychology paints a picture of people as motivated reasoners. Instead of having an open-minded engagement with issues, individuals typically only seek, see, and understand information in a manner that reinforces what they already believe. Here, we examine motivated reasoning and argue that the strongest partisans and the most committed ideologues will be the most susceptible to holding contradictory policy positions with regard to same-sex marriage and religious freedom.

    Knowledge modelling, a main activity for the development of Knowledge Based Systems, have no set standards and are mostly done in an ad hoc way. There is a lack of support for the transition from abstract level to implementation. In this paper, a methodology for the development of the knowledge model, which is inspired by both Software and Knowledge Engineering, is proposed. Use of UML which is the de-facto standard for modelling in the software engineering arena is explored for knowledge mod...
