Full Text Available Purpose: Primary bond markets represent an interesting investment opportunity not only for banks, insurance companies, and other institutional investors, but also for individuals looking for capital gains. Since offered securities vary in terms of their rating, industrial classification, coupon, or maturity, demand of buyers for particular offerings often overcomes issued volume and price of given bond on secondary market consequently rises. Investors might be regarded as consumers purchasing required service according to their specific preferences at desired price. This paper aims at analysis of demand for bonds on primary market using artificial neural networks.Design/methodology: We design a multilayered feedforward neural network trained by Levenberg-Marquardt algorithm in order to estimate demand for individual bonds based on parameters of particular offerings. Outcomes obtained by artificial neural network are compared with conventional econometric methods.Findings: Our results indicate that artificial neural network significantly outperformed standard econometric techniques and on examined sample of primary bond offerings achieved considerably better performance in terms of prediction accuracy and mean squared error.Originality: We show that proposed neural network is able to successfully predict demand for primary obligation offerings based on their specifications. Moreover, we identify relevant parameters of issues which are able to considerably affect total demand for given security. Our findings might not only help investors to detect marketable securities, but also enable issuing entities to increase demand for their bonds in order to decrease their offering price.

The BP model in artificial neural network is used in this paper. Various factors that affect the tender offer is identified and these factors as the input nodes of network to conduct iterated operation in the network is applied in this paper. Through taking advantage of the self-learning function of network, this paper constantly modifies the weight matrix to achieve the objective error of the network error to achieve the function of predicting offer. As a software support tool, MATLAB is used in artificial neural network, the neural network toolbox helps to reduce the workload of writing code greatly and make the application of neural network more widely.

The world is confronted with a variety of interdependent problems, including scarcity, unsustainability, inequality, pollution and poor governance. Tackling such complex challenges requires coordinated action. The present paper proposes the development of a self-organizing system for coordination, called an "offer network", that would use the distributed intelligence of the Internet to match the offers and needs of all human, technological and natural agents on the planet. This would maximize synergy and thus minimize waste and scarcity of resources. Implementing such coordination requires a protocol that formally defines agents, offers, needs, and the network of condition-action rules or reactions that interconnect them. Matching algorithms can then determine self-sustaining subnetworks in which each consumed resource (need) is also produced (offer). After sketching the elements of a mathematical foundation for offer networks, the paper proposes a roadmap for their practical implementation. This includes step-by-step integration with technologies such as the Semantic Web, ontologies, the Internet of Things, reputation and recommendation systems, reinforcement learning, governance through legal constraints and nudging, and ecosystem modeling. The resulting intelligent platform should be able to tackle nearly all practical and theoretical problems in a bottom-up, distributed manner, thus functioning like a Global Brain for humanity.

Full Text Available Although the number of initiatives of place promotion, the Abruzzo tourism offer remains essentially polarized around two basic segments (the seaside/summer segment and the mountain/snow-based one and it strongly depends on the proximate tourist demand. Actually the Abruzzo region holds a wider and varied heritage, composed by cultural attractions, historical and architectural resources, wine and food potential and, more generally speaking, a lot heterogeneous environments and landscapes. These resources could respond to the new philosophies of tourism demand, characterised by the experiential motivations of peacefulness, tranquility and soul regeneration in a very close contact with nature. The goal of this study is to evaluate the potential tourism usability of the Abruzzo cultural heritage assessing the levels of the distribution of accommodation facilities and attractiveness. A more aware and integrated tourism offer may produce complementarities both at product and territory levels and may also absorb some critical issues of the regional tourism industry (no awareness of cultural tourism potential, the fragmentation of public policies, the inability to cooperate with a networking mentality.

Syndromes resulting in Disorders of Sex Development (DSD) are individually rare. Historically, this fact has hindered both clinical research and the delivery of evidence-based care. Recognizing the need for advancement, members of European and North American medical societies produced policy statements, notably the Consensus Statement on Management of Intersex Disorders, which recognize that optimal healthcare in DSD requires multidisciplinary teams in conjunction with networking of treatment centers and continued development of patient registries. This paper summarizes efforts in Europe and the U.S. toward creating networks focused on expanding discovery and improving healthcare and quality of life outcomes in DSD. The objectives and function of registry-based networks (EuroDSD/I-DSD), learning collaboratives (DSD-net), clinical outcomes research (DSD-Life), and networking hybrids (DSD-TRN) are reviewed. Opportunities for, and barriers to standardization in research and care are highlighted in light of practical considerations, for example, limitations in reliably classifying anatomic phenotypes and gaps in behavioral health staffing resources. The role of patient-reported outcomes is considered, with emphasis on integrating patient perspectives, given findings of limited agreement in outcome ratings by healthcare providers and patients. Finally, the characteristics of clinical centers likely to deliver the highest quality outcomes are discussed. © Georg Thieme Verlag KG Stuttgart · New York.

Volcanoes have always fascinated people for the wild beauty of their landscapes and also for the fear that they arouse with their eruptive actions, sometimes simply spectacular, but other times terrifying and catastrophic for human activities. In the past, volcanoes were sometimes imagined as a metaphysical gateway to the otherworld; they have inspired the creation of myths and legends ever since three thousand years ago, also represented by paintings of great artistic impact. Modern technology today offers very sophisticated and readily accessed digital tools, and volcanoes continue to be frequently photographed and highly appreciated natural phenomena. Moreover, in recent years, the spread of social networks (Facebook, Twitter, YouTube, Instagram, etc.) have made the widespread dissemination of graphic contributions even easier. The result is that very active and densely inhabited volcanoes such as Etna, Vesuvius and Aeolian Islands, in Italy, have become among the most photographed subjects in the world, providing a popular science tool with formidable influence and usefulness. The beauty of these landscapes have inspired both professional artists and photographers, as well as amateurs, who compete in the social networks for the publication of the most spectacular, artistic or simply most informative images. The end result of this often frantic popular scientific activity is at least two-fold: on one hand, it provides geoscientists and science communicators a quantity of documentation that is almost impossible to acquire through the normal systems of volcano monitoring, while on the other it raises awareness and respect for the land among the civil community.

functions mentioned above. As VLSI minimum feature sizes decrease, the optimum grain size increases, whereas, if optical interconnect performance in terms of the detector power or modulator driving voltage requirements improves, the optimum grain size may be reduced. Finally, several architectural modifications to the system, such as K x K contention-free switches and sorting networks, are investigated and optimized for grain size. Results indicate that system bandwidth can be increased, but at the price of reduced performance/cost. The optoelectronic MIN architectures considered thus provide a broad range of performance/cost alternatives and offer a superior performance over purely electronic MIN's.

Software Defined Networking (SDN) is an evolutionary approach to network design and functionality based on the ability to programmatically modify the behavior of network devices. SDN uses user-customizable and configurable software that's independent of hardware to enable networked systems to expand data flow control. SDN is in large part about understanding and managing a network as a unified abstraction. It will make networks more flexible, dynamic, and cost-efficient, while greatly simplifying operational complexity. And this advanced solution provides several benefits including network and service customizability, configurability, improved operations, and increased performance. There are several approaches to SDN and its practical implementation. Among them, two have risen to prominence with differences in pedigree and implementation. This paper's main focus will be to define, review, and evaluate salient approaches and use cases of the OpenFlow and Virtual Network Overlay approaches to SDN. OpenFlow is a communication protocol that gives access to the forwarding plane of a network's switches and routers. The Virtual Network Overlay relies on a completely virtualized network infrastructure and services to abstract the underlying physical network, which allows the overlay to be mobile to other physical networks. This is an important requirement for cloud computing, where applications and associated network services are migrated to cloud service providers and remote data centers on the fly as resource demands dictate. The paper will discuss how and where SDN can be applied and implemented, including research and academia, virtual multitenant data center, and cloud computing applications. Specific attention will be given to the cloud computing use case, where automated provisioning and programmable overlay for scalable multi-tenancy is leveraged via the SDN approach.

Online social networks (OSNs) have rapidly become a prominent and widely used service, offering a wealth of personal and sensitive information with significant security and privacy implications. Hence, OSNs are also an important--and popular--subject for research. To perform research based on real-life evidence, however, researchers may need to access OSN data, such as texts and files uploaded by users and connections among users. This raises significant ethical problems. Currently, there are no clear ethical guidelines, and researchers may end up (unintentionally) performing ethically questionable research, sometimes even when more ethical research alternatives exist. For example, several studies have employed "fake identities" to collect data from OSNs, but fake identities may be used for attacks and are considered a security issue. Is it legitimate to use fake identities for studying OSNs or for collecting OSN data for research? We present a taxonomy of the ethical challenges facing researchers of OSNs and compare different approaches. We demonstrate how ethical considerations have been taken into account in previous studies that used fake identities. In addition, several possible approaches are offered to reduce or avoid ethical misconducts. We hope this work will stimulate the development and use of ethical practices and methods in the research of online social networks.

Conducting nanowire networks have been developed as viable alternative to existing indium tin oxide based transparent electrode (TE). The nature of electrical conduction and process optimization for electrodes have gained much from the theoretical models based on percolation transport using Monte Carlo approach and applying Kirchhoff's law on individual junctions and loops. While most of the literature work pertaining to theoretical analysis is focussed on networks obtained from conducting rods (mostly considering only junction resistance), hardly any attention has been paid to those made using template based methods, wherein the structure of network is neither similar to network obtained from conducting rods nor similar to well periodic geometry. Here, we have attempted an analytical treatment based on geometrical arguments and applied image analysis on practical networks to gain deeper insight into conducting networked structure particularly in relation to sheet resistance and transmittance. Many literature examples reporting networks with straight or curvilinear wires with distributions in wire width and length have been analysed by treating the networks as two dimensional graphs and evaluating the sheet resistance based on wire density and wire width. The sheet resistance values from our analysis compare well with the experimental values. Our analysis on various examples has revealed that low sheet resistance is achieved with high wire density and compactness with straight rather than curvilinear wires and with narrower wire width distribution. Similarly, higher transmittance for given sheet resistance is possible with narrower wire width but of higher thickness, minimal curvilinearity, and maximum connectivity. For the purpose of evaluating active fraction of the network, the algorithm was made to distinguish and quantify current carrying backbone regions as against regions containing only dangling or isolated wires. The treatment can be helpful in
This letter proposes a dynamic bandwidth allocation algorithm for access networks based PON (Passive Optical Network). It considers the mixture of transport layer protocols when responding to traffic congestion at the SNI (Service Node Interface). Simulations on a mixture of TCP (Transmission Control Protocol), and UDP (User Datagram Protocol) traffic flows show that the algorithm increases the throughput of TCP, improves the fairness between the two protocols, and solves the congestion problem at the SNI.

Presentation and discussion of lessons learnt from: (i) the monitoring and analysis of web and social network contents on vaccination; (ii) the tracking of Google search terms used by web users; (iii) the analysis of Google search suggestions related to vaccination; (iv) results from the Vaccinoscopie(©) study, online annual surveys of representative samples of 6500 to 10,000 French mothers, monitoring vaccine behaviors and attitude of French parents as well as vaccination coverage of their children, since 2008; and (v) various studies published in the scientific literature. Social networks and the web play a major role in disseminating information about vaccination. They have modified the vaccination decision-making process and, more generally, the doctor/patient relationship. The Internet may fuel controversial issues related to vaccination and durably impact public opinion, but it may also provide new tools to fight against vaccine hesitancy. Vaccine hesitancy should be fought on the Internet battlefield, and for this purpose, communication strategies should take into account new threats and opportunities offered by the web and social networks.

Online social networking refers to the use of internet-based technologies that facilitate connection and communication between users. These platforms may be accessed via computer or mobile device (e.g., tablet, smartphone); communication between users may include linking of profiles, posting of text, photo and video content, instant messaging and email. This review provides an overview of recent research on the relationship between online social networking and sexual risk and protective behaviors with a focus on use of social networking sites (SNS) among young people and populations at high risk for sexually transmitted infections (STIs). While findings are mixed, the widespread use of SNS for sexual communication and partner seeking presents opportunities for the delivery and evaluation of public health interventions. Results of SNS-based interventions to reduce sexual risk are synthesized in order to offer hands-on advice for clinicians and researchers interested in engaging patients and study participants via online social networking.

Feeding young children successfully requires parenting skills, trust that children will eat, and nutrition and child development knowledge to ensure that foods and the amounts offered are developmentally appropriate. Mothers are often responsible for determining how much food is offered to their children; however, the influences on mothers' decisions regarding how much to offer their children--their motivations, goals for feeding and child consumption--have not been investigated. Study aims included gathering qualitative data regarding mothers' decisional processes related to preparing a dinner meal plate for her preschooler. Low income mothers (n = 15 African American and n = 15 Latina mothers) were recruited from preschools in the Denver, CO metropolitan area to participate in semi-structured interviews. Mothers prepared a plate for their preschooler and were asked about influences on their decisions about portion sizes and their expectations for children's eating. Data were coded by 2 independent coders using a consensus coding process and analyzed by investigators. Three themes emerged: (1) portion sizes differ for children who are "good" eaters and "picky" eaters; (2) mothers know the "right amounts" to serve their child; and (3) mothers have emotional investments in their children's eating. Some influencing factors were child-centered (e.g. child's likes and dislikes, "picky" and "good" eaters, and foods previously eaten in the day) and some related to adult expectations and concerns (nutrient content and waste). Interventions focusing on portion size may be more effective if tailored to the mothers' perceptions regarding her child's eating characteristics. Published by Elsevier Ltd.

Full Text Available Voice data packets have to arrive at the destination in time, with a defined cadence and with low and constant delay in order to allow the real time voice reconstruction. From this point of view, transmitting voice over IP networks is the most sensitive category of applications, especially when wireless medium is involved. The paper discusses the possibilities of transmitting the maximum number of simultaneous voice streams over 802.11 wireless networks considering the main factors which impact with VoIP throughput, in a basic scenario. Starting from a proposed communication model, the number of simultaneous possible VoIP sessions is calculated, taking into consideration the contribution of the protocol overheads, the security overheads, the PHY level timings and the CODEC proprieties. Numerical results are generated and compared.
Full Text Available The recent influx of electronic medical records in the health care field, coupled with the need of providing continuous care to patients in the critical care environment, has driven the need for interoperability of medical devices. Open standards are needed to support flexible processes and interoperability of medical devices, especially in intensive care units. In this paper, we present an interoperable networking and access architecture based on the CAN protocol. Predictability of the delay of medical data reports is a desirable attribute that can be realized using a tightly-coupled system architecture. Our simulations on network architecture demonstrate that a bounded delay for event reports offers predictability. In addition, we address security issues related to the storage of electronic medical records. We present a set of open source tools and tests to identify the security breaches, and appropriate measures that can be implemented to be compliant with the HIPAA rules.

Full Text Available The Ibero-American Map of Atmospheric Corrosiveness (MICAT project was set up in 1988 sponsored by the International Ibero-American programme “Science and Technology for Development (CYTED” and ended in 1994 after six years of activities. Fourteen countries were involved in this project: Argentina, Brazil, Chile, Colombia, Costa Rica, Cuba, Ecuador, Mexico, Panama, Peru, Portugal, Spain, Uruguay, and Venezuela. Research was conducted both at laboratories and in a network of 75 atmospheric exposure test sites throughout the Ibero-American region, thus considering a broad spectrum of climatological and pollution conditions. Although with its own peculiarities, the project basically followed the outline of the ISOCORRAG and ICP/UNECE projects, with the aim of a desirable link between the three projects. This paper summarizes the results obtained in the MICAT project for mild steel, zinc, copper, and aluminum specimens exposed for one year in different rural, urban, and marine atmospheres in the Ibero-American region. Complementary morphological and chemical studies were carried out using scanning electron microscopy (SEM coupled with energy dispersive spectrometry (EDS, X-ray diffraction (XRD, and fourier transform infrared Spectroscopy (FTIR techniques, in order to correlate climatic and atmospheric conditions and properties of the corrosion products.

This paper proposes a new model of simultaneous optimization of three-level logistics decisions, for logistics authorities, logistics operators, and logistics users, for regional logistics network with environmental impact consideration. The proposed model addresses the interaction among the three logistics players in a complete competitive logistics service market with CO2 emission charges. We also explicitly incorporate the impacts of the scale economics of the logistics park and the logistics users' demand elasticity into the model. The logistics authorities aim to maximize the total social welfare of the system, considering the demand of green logistics development by two different methods: optimal location of logistics nodes and charging a CO2 emission tax. Logistics operators are assumed to compete with logistics service fare and frequency, while logistics users minimize their own perceived logistics disutility given logistics operators' service fare and frequency. A heuristic algorithm based on the multinomial logit model is presented for the three-level decision model, and a numerical example is given to illustrate the above optimal model and its algorithm. The proposed model provides a useful tool for modeling competitive logistics services and evaluating logistics policies at the strategic level. PMID:24977209

Full Text Available In this paper, we study the impact of collisions and interferences on a neighbor discovery process in the context of multi-hop wireless networks. We consider three models in which interferences and collisions are handled in very different ways. From an ideal channel where simultaneous transmissions do not interfere, we derive an alternate channel where simultaneous transmissions are considered two-by-two under the form of collisions, to finally reach a more realistic channel where simultaneous transmissions are handled under the form of shot-noise interferences. In these models, we analytically compute the link probability success between two neighbors as well as the expected number of nodes that correctly receive a Hello packet. Using this analysis, we show that if the neighbor discovery process is asymptotically equivalent in the three models, it offers very different behaviors locally in time. In particular, the scalability of the process is not the same depending on the way interferences are handled. Finally, we apply our results to the dimensioning of a Hello protocol parameters. We propose a method to adapt the protocol parameters to meet application constraints on the neighbor discovery process and to minimize the protocol energy consumption.
Recent years have experienced a huge influx of daily life applications based on embedded wireless networks.

The Base Station (BS) sleeping strategy has become a well-known technique to achieve energy savings in cellular networks by switching off redundant BSs mainly for lightly loaded networks. Besides, the exploitation of renewable energies, as additional power sources in smart grids, becomes a real challenge to network operators to reduce power costs. In this paper, we propose a method based on genetic algorithms that decreases the energy consumption of a Long-Term Evolution (LTE) cellular network by not only shutting down underutilized BSs but also by optimizing the amounts of energy procured from the smart grid without affecting the desired Quality of Service. © 2012 Springer-Verlag.
Full Text Available Fruška gora lakes Sot, Bruje and Moharač are the lakes that can be used in many ways for sports and recreation tourism. Nevertheless, the current tourism offer in these lakes is based only on offer for sports fishing. Bearing in mind that Fruška gora National Park, where there are three zones of protection, is of great importance the fact that the second and third zones are, with regard to territorial perspective, areas where it is desirable to develop sports and recreational tourism. Cycling is becoming an increasingly popular form of sports and recreational tourism, so tourism networking of Fruška gora lakes with system of cycle paths would represent only the first step to turn the whole mountain into the European cycle mainstream. In this sense, the aim of this paper is set to map the FJSA cycling paths connected to the system. The field research resulted in the mapping of the terrain. The interviews with experts from the Provincial Secretariat of Environmental Protection, the National Park and the Cycling Association of Vojvodina helped in the SWOT analysis of cycle tourism on Fruška gora lakes.

Packet technologies were designed to work in asynchronous mode, where the oscillators in the equipment are free running. Although this allows the underlying infrastructure to operate, many applications exist that require frequency synchronization. Also, the ability to distribute synchronization from center to edge of network declines as infrastructure evolves toward a packet-based architecture. Synchronous Ethernet (SyncE) is a key development of the evolution of Ethernet into a carrier grade technology suitable for the WAN environment where frequency synchronization is required. The time of the day distribution in synchronized network at the physical layer enables many useful propositions in packet handling policies and other network management aspects.
This paper investigates the collaboration between multiple mobile operators to optimize the energy efficiency of cellular networks. Our framework studies the case of LTE-Advanced networks deployed in the same area and owning renewable energy generators. The objective is to reduce the CO2 emissions of cellular networks via collaborative techniques and using base station sleeping strategy while respecting the network quality of service. Low complexity and practical algorithm is employed to achieve green goals during low traffic periods. Cooperation decision criteria are also established basing on derived roaming prices and profit gains of competitive mobile operators. Our numerical results show a significant save in terms of CO2 compared to the non-collaboration case and that cooperative mobile operator exploiting renewables are more awarded than traditional operators.

Full Text Available The number of large sensor systems is rapidly growing nowadays in many fields. Well-designed Big Data solutions are able to manage the enormous data flow and create real business benefits. One dynamically growing application area is precision farming. It requires robust and energy- efficient sensors, because the devices are placed outdoors, often in harsh conditions, and there is no power outlet “in the middle of a corn field”. Power efficiency is in general one of the major themes of the Internet of Things (IoT. According to the IoT vision, embedded sensors send their data to processing units (either located near to the sensor or on some intermediate ”gateway” device or in the cloud using heterogeneous transport networks. Some sensors employ short-range network like Bluetooth and some ”gateway” device like a tablet. Other sensors directly connect to wide-area networks like cellular networks. This paper will analyze different communication patterns accomplished over GSM network from the viewpoint of the energy consumption of the sensor device with the assumption that the sensor is stationary. The measurements were done using two different GSM modems designed for embedded systems to ensure that the results represent a wider picture and not some implementation property of a particular GSM modem. Recommendations are given about the strategies applications should follow in order to minimize the energy consumption of their GSM subsystems.
Full Text Available Biological organisms do not evolve to perfection, but to out compete others in their ecological niche, and therefore survive and reproduce. This paper reviews the constraints imposed on imperfect organisms, particularly on their neural systems and ability to capture and process information accurately. By understanding biological constraints of the physical properties of neurons, simpler and more efficient artificial neural networks can be made (e.g., spiking networks will transmit less information than graded potential networks, spikes only occur in nature due to limitations of carrying electrical charges over large distances. Furthermore, understanding the behavioural and ecological constraints on animals allows an understanding of the limitations of bio-inspired solutions, but also an understanding of why bio-inspired solutions may fail and how to correct these failures.
Full Text Available This paper proposes an efficient approach for transmission network expansion planning. Three indicators are proposed to evaluate the planning, which is the power grid vulnerability, wind power accommodation and operation cost. Vulnerability is evaluated based on the complex network theory, and wind power accommodation analysis is performed by the rate of abandoned wind power. The optimization of transmission network expansion planning is translated into constraints multi-objective optimization problem. A novel QS-MOWE algorithm based on the improvement quick sort and NSGA-II algorithm has been proposed. The method can be used effectively to study the effect of increasing wind power integration and vulnerability with high wind generation uncertainties. The model and algorithms are applied to calculate a case of 6 units. The results show that the proposed modeling method can provide a useful guidance for planning problems.

Wireless Sensor Networks (WSNs) are composed of spatially distributed autonomous sensor devices, named motes. These motes have their own power supply, processing unit, sensors and wireless communications However with many constraints, such as limited energy, bandwidth and computational capabilities. In these networks, at least one mote called a sink, acts as a gateway to connect with other networks. These sensor networks run monitoring applications and then the data gathered by these motes needs to be retrieved by the sink. When this sink is located in the far field, there have been many proposals in the literature based on Collaborative Beamforming (CB), also known as Distributed or Cooperative Beamforming, for these long range communications to reach the sink. In this paper, we conduct a thorough study of the related work and analyze the requirements to do CB. In order to implement these communications in real scenarios, we will consider if these requirements and the assumptions made are feasible from the point of view of commercial motes and their constraints. In addition, we will go a step further and will consider different alternatives, by relaxing these requirements, trying to find feasible assumptions to carry out these types of communications with commercial motes. This research considers the nonavailability of a central clock that synchronizes all motes in the WSN, and all motes have identical hardware. This is a feasibility study to do CB on WSN, using a simulated scenario with randomized delays obtained from experimental data from commercial motes.

Behavioral neuroendocrinology is an integrative discipline that spans a wide range of taxa and neural systems, and thus the appropriate designation of homology (sameness) across taxa is critical for clear communication and extrapolation of findings from one taxon to another. In the present review we address issues of homology that relate to neural circuits of social behavior and associated systems that mediate reward and aversion. We first address a variety of issues related to the so-called "social behavior network" (SBN), including homologies that are only partial (e.g., whereas the preoptic area of fish and amphibians contains the major vasopressin-oxytocin cell groups, these populations lie in the hypothalamus of other vertebrates). We also discuss recent evidence that clarifies anterior hypothalamus and periaqueductal gray homologies in birds. Finally, we discuss an expanded network model, the "social decision-making network" (SDM) which includes the mesolimbic dopamine system and other structures that provide an interface between the mesolimbic system and the SBN. This expanded model is strongly supported in mammals, based on a wide variety of evidence. However, it is not yet clear how readily the SDM can be applied as a pan-vertebrate model, given insufficient data on numerous proposed homologies and a lack of social behavior data for SDM components (beyond the SBN nodes) for amphibians, reptiles or fish. Functions of SDM components are also poorly known for birds. Nonetheless, we contend that the SDM model provides a very sound and important framework for the testing of many hypotheses in nonmammalian vertebrates. Copyright © 2013 Elsevier Inc.

Friendship tie choices in adolescent social networks coevolve simultaneously with youths' cigarette smoking and drinking. We estimate direct and multiplicative relationships between both peer influence and peer selection with salient parental factors affecting both friendship tie choice and the use of these 2 substances. We utilize 1 sample of 12 small schools and a single large school extracted from the National Longitudinal Study of Adolescent to Adult Health. Using a Stochastic Actor-Based modeling approach over 3 waves, we find: (a) a peer selection effect, as adolescents nominated others as friends based on cigarette and alcohol use levels across samples; (b) a peer influence effect, as adolescents adapted their smoking and drinking behaviors to those of their best friends across samples; (c) reciprocal effect between cigarette and alcohol usage in the small school sample; (d) a direct effect of parental support and the home smoking environment on adolescent friendship tie choice in the small school sample; (e) a direct effect of the home smoking environment on smoking across samples; (f) a direct effect of the home drinking environment on alcohol use across samples; and (g) a direct effect of parental monitoring on alcohol use across samples. We observed an interaction between parental support and peer influence in affecting drinking, and an interaction between the home drinking environment and peer influence on drinking, in the small school sample. Our findings suggested the importance of delineating direct and synergistic pathways linking network processes and parental influence as they affect concurrent cigarette and alcohol use.

Full Text Available Mass media play a role in social changes by influencing the public opinion during phases of preparation, implementation and justification of performed changes. Social changes in the global age, especially those of greater scope, are hardly imaginable without the role of mass media. Mass media as an instrument of influence over public opinion is used in both cases - when a change goes from 'down' or from 'up'. With regards to the changes initiated by the power holders, the means of impact usually used are classic mass media-newspapers, radio, television, and more often, Internet. However, in cases when the initiators of changes are on lower levels of social hierarchy, the first choice is Internet due to its accessibility and decentralized structure. Internet had demonstrated its influence on social changes earlier, but that influence was especially visible during the 'Arab spring'. The 'Arab spring' is a collective name for a wave of protests and changes which sparked in Tunisia in December 2010 and spilled over to other countries of the northern Africa and Near East. Egypt, Syria, Bahrain, Sudan, Libya, Morocco, Yemen, Algeria are some of them. Due to their prominent role in dissemination of information, the Tunisian episode of the 'Arab spring' is called Facebook revolution or Internet revolution, which clearly indicates which media and social networks had played key role in change of government in Tunisia. Mobile phone, being media of interpersonal communication, have also played significant role in case of Tunisia, the same role mass media had in changes of real-socialist systems. Development of new technologies and their application in field of communication means have revolutionized the communication process. Naturally, television has also played its role in the 'Arab spring'. Bearing in mind that national media services are mostly controlled by the governing elite, the news on rebellion in Tunisia were spread through global media
Full Text Available Cost optimization in the synthesis decision tree often leads to a reduced degree of freedom which degrades the process's ability to reject disturbances as a consequence of low controllability. In fact, Heat Exchanger Networks (HENs obtained by traditional synthesis procedures that ignore controllability aspects must be evaluated in this context a posteriori. The aim of this work was to develop a procedure that includes RGA and SVD measures of controllability, which are solely based on steady state information, thereby freeing the synthesis procedure of the cumbersome dynamic analysis. When a structure is defined during a traditional HEN synthesis procedure, a degree of freedom analysis is approached as a simulation problem. Next, an optimization is performed, since new variables are usually added to increase the degree of freedom of the HEN in order to render it controllable. A key point in the proposed procedure is the inference of controllability based on the proposed controllability measures, which also provide a control scheme by pairing controlled and manipulated variables during the process design. A HEN reported in the literature is used to illustrate the proposed procedure. The steady state simulator Aspen Plus and the dynamic simulator Aspen Dynamics (Aspentech, Inc. were employed.

The patch-clamp technique is generally accepted as the gold standard for studying ion channel activity allowing investigators to either "clamp" membrane voltage and directly measure transmembrane currents through ion channels, or to passively monitor spontaneously occurring intracellular voltage oscillations. However, this resulting high information content comes at a price. The technique is labor-intensive and requires highly trained personnel and expensive equipment. This seriously limits its application as an interrogation tool for drug development. Patch-clamp chips have been developed in the last decade to overcome the tedious manipulations associated with the use of glass pipettes in conventional patch-clamp experiments. In this chapter, we describe some of the main materials and fabrication protocols that have been developed to date for the production of patch-clamp chips. We also present the concept of a patch-clamp chip array providing high resolution patch-clamp recordings from individual cells at multiple sites in a network of communicating neurons. On this chip, the neurons are aligned with the aperture-probes using chemical patterning. In the discussion we review the potential use of this technology for pharmaceutical assays, neuronal physiology and synaptic plasticity studies.
Full Text Available In recent years, deep neural networks (DNN have demonstrated significant business impact in large scale analysis and classification tasks such as speech recognition, visual object detection, pattern extraction, etc. Training of large DNNs, however, is universally considered as time consuming and computationally intensive task that demands datacenter-scale computational resources recruited for many days. Here we propose a concept of resistive processing unit (RPU devices that can potentially accelerate DNN training by orders of magnitude while using much less power. The proposed RPU device can store and update the weight values locally thus minimizing data movement during training and allowing to fully exploit the locality and the parallelism of the training algorithm. We evaluate the effect of various RPU device features/non-idealities and system parameters on performance in order to derive the device and system level specifications for implementation of an accelerator chip for DNN training in a realistic CMOS-compatible technology. For large DNNs with about 1 billion weights this massively parallel RPU architecture can achieve acceleration factors of 30,000X compared to state-of-the-art microprocessors while providing power efficiency of 84,000 GigaOps/s/W. Problems that currently require days of training on a datacenter-size cluster with thousands of machines can be addressed within hours on a single RPU accelerator. A system consisting of a cluster of RPU accelerators will be able to tackle Big Data problems with trillions of parameters that is impossible to address today like, for example, natural speech recognition and translation between all world languages, real-time analytics on large streams of business and scientific data, integration and analysis of multimodal sensory data flows from a massive number of IoT (Internet of Things sensors.

For large DNNs with about 1 billion weights this massively parallel RPU architecture can achieve acceleration factors of 30, 000 × compared to state-of-the-art microprocessors while providing power efficiency of 84, 000 GigaOps∕s∕W. Problems that currently require days of training on a datacenter-size cluster with thousands of machines can be addressed within hours on a single RPU accelerator. A system consisting of a cluster of RPU accelerators will be able to tackle Big Data problems with trillions of parameters that is impossible to address today like, for example, natural speech recognition and translation between all world languages, real-time analytics on large streams of business and scientific data, integration, and analysis of multimodal sensory data flows from a massive number of IoT (Internet of Things) sensors.

Actor-Network Theory is a research lens that has gained popularity in the nursing and health sciences domains. The perspective allows a researcher to describe the interaction of actors (both human and non-human) within networked sociomaterial contexts, including complex practice environments where nurses and health technology operate. This study will describe Actor-Network Theory and provide methodological considerations for researchers who are interested in using this sociotechnical lens within nursing and informatics-related research. Considerations related to technology conceptualization, levels of analysis, and sampling procedures in Actor-Network Theory based research are addressed. Finally, implications for future nursing research within complex environments are highlighted. © 2015 John Wiley & Sons Ltd.
The relative influence of team climate, team norms and social network norms on health professionals' implementation of a national recommendation to offer service-users diagnosed with schizophrenia family intervention therapy.
Social influence is an important variable influencing health professionals' adoption of clinical recommendations. Different theories conceptualise social influence in different ways. This study operationalised three different forms of social influence--team climate, team norms (descriptive and injunctive) and social network norms (descriptive and injunctive), and compared their ability to predict mental health professionals' self-reported intention to adopt a national, clinical recommendation. A cross-sectional survey was developed, measuring the constructs in relation to intention to offer service-users family an intervention therapy, as part of a larger, theory-based implementation study. The survey was administered to all mental health professionals in one mental health trust. Using multiple regression, descriptive network norms were found to be the only significant predictor of intention. This suggests that behaviour change interventions in this context may benefit from promoting descriptive network norms, for example, emphasising the adoption behaviour of influential peers. Given the high degree of overlap found between network and team members in this study, and the potential challenges of targeting behaviour-change interventions at informal, more difficult to identify networks, future research is needed to evaluate the feasibility of targeting behaviour-change interventions at social networks compared with formal teams.

Policy makers in Sweden and other European Member States pay increasing attention as to how best support working carers; carers juggling providing unpaid family care for older family members while performing paid work. Exploring perceived benefits and challenges with web-based information and communication technologies as a means of supporting working carers' in their caregiving role, this paper draws on findings from a qualitative study. The study aimed to describe working carers' experiences of having access to the web-based family care support network 'A good place' (AGP) provided by the municipality to support those caring for an older family member. Content analysis of interviews with nine working carers revealed three themes: A support hub, connections to peers, personnel and knowledge; Experiencing ICT support as relevant in changing life circumstances; and Upholding one's personal firewall. Findings indicate that the web-based family care support network AGP is an accessible, complementary means of support. Utilising support while balancing caregiving, work obligations and responsibilities was made easier with access to AGP; enabling working carers to access information, psychosocial support and learning opportunities. In particular, it provided channels for carers to share experiences with others, to be informed, and to gain insights into medical and care issues. This reinforced working carers' sense of competence, helping them meet caregiving demands and see positive aspects in their situation. Carers' low levels of digital skills and anxieties about using computer-based support were barriers to utilising web-based support and could lead to deprioritising of this support. However, to help carers overcome these barriers and to better match web-based support to working carers' preferences and situations, web-based support must be introduced in a timely manner and must more accurately meet each working carer's unique caregiving needs. © 2016 Nordic College

With the rapid development of the energy networks, various forms of renewable energy resources are absorbed into it. Because of the inherent random behaviour of the renewable resources, introducing them into the energy network will destroy the stability of the grids. It is required to use proper energy storages to reduce the uncertain fluctuation from the renewable energy resources. For a concrete model research, this paper presented an explicit method to give suitable capacities of the energy storages in consideration of the economics of the storage, grid losses and the probabilities of the bus voltages violation, for situations of the winds-power generations injected into the power network. Furthermore, the influence of the correlation between the different winds farms on the optimal storage capacity can also be studied by this method.

Sensors Unlimited, Inc., with SBIR funding from NASA's Langley Research Center, Goddard Space Flight Center, Marshall Space Flight Center, and the Jet Propulsion Laboratory, developed a monolithic focal plane array for near-infrared imaging. The company developed one- (1- D) and two-dimensional (2-D) imaging arrays consisting of a highly reliable InGaAs p-I-n diode as a photodetector for monitoring a variety of applications, including single element device applications in receivers. The InGaAs 1-D and 2-D arrays have many applications. For example, they monitor the performance of dense wavelength division multiplexing (DWDM) systems- the process of packaging many channels into a single fiber-optic cable. Sensors Unlimited commercially offers its LXTM and LYTM Series InGaAs linear arrays for reliable DWDM performance monitoring. The LX and LY arrays enable instrument module designs with no moving parts, which provides for superior uniformity, and fast, linear outputs that remain stable over a wide temperature range. Innovative technologies derived from the monolithic focal plane array have enabled telecommunication companies to optimize existing bandwidth in their fiber-optic networks in order to support a high volume of network traffic. At the same time, the technologies obtained from the array have the potential for reducing costs, while increasing performance from Sensors Unlimited's current product lines.
Full Text Available Wireless medical body-area networks are used to connect sensor nodes that monitor vital parameters. The radio consumes a large portion of the sensor energy budget, and hence its power dissipation should be minimized. The low-noise amplifier (LNA is an important component of the receiver, and must guarantee low-noise amplification and impedance matching. In this work, an ultra-low-voltage ultra-low-power LNA is proposed that, thanks to the proposed transformer-based gate boosting technique, has a reduced current consumption of only 160 μA and can operate with a supply as low as 0.18 V. The LNA was designed using 40 nm Complementary Metal-Oxide Semiconductor (CMOS technology and features a voltage gain of 14 dB, 5.2 dB NF and −8.6 dBm IIP3. This performance is comparable to a prior work by the same authors, but with the minimum supply voltage reduced by a factor of 4x.

Marriages and other intimate partnerships are facilitated or constrained by the social networks within which they are embedded. To date, methods used to assess the social networks of couples have been limited to global ratings of social network characteristics or network data collected from each partner separately. In the current article, the authors offer new tools for expanding on the existing literature by describing methods of collecting and analyzing duocentric social networks, that is, the combined social networks of couples. They provide an overview of the key considerations for measuring duocentric networks, such as how and why to combine separate network interviews with partners into one shared duocentric network, the number of network members to assess, and the implications of different network operationalizations. They illustrate these considerations with analyses of social network data collected from 57 low-income married couples, presenting visualizations and quantitative measures of network composition and structure.

Full Text Available Aim: To know the official masters that the Spanish Universities have offered during the academic course 2010/2011.Material and methods: Descriptive observational and transversal court study, in which it has analysed 170 university official masters and in which it has used a questionnaire with a total of 15 questions elaborated for this work.Results: 52 Spanish Universities of the 75 that there is have offered during the academic course 2010/2011 official masters that can realise for graduated in infirmary. By areas, the official masters more offered have been the ones of nutrition and alimentary security. 76,33% of the official masters have a length of 1 academic year. Almost the half of the official masters have an orientation researcher-professional and almost 40% researcher. 62,65% of the masters give of face-to-face way. In 52,1% of the official masters do not realise external practices and 86,2% has continuity with the doctorate.Conclusions: It has seen that it is necessary that expand the number of masters including other fields of study that contribute to a main specialisation of the professionals of the infirmary. An important percentage of official masters give in face-to-face modality, and there is very few offered on-line or to distance.
Effective feedback on performance is an integral part of clinical training. It allows the trainee to critically reflect on their development, as well as enable the teacher to chart progress and detect areas for development. In order to provide effective feedback, we need to take into account the performance itself, but also the setting where feedback is offered, and the expected outcomes of the encounter. As ever, negative feedback remains more difficult to give and receive, and as such requires a greater degree of delicacy to produce a positive result.

The research method used for creating this article is documentary study. The tourist offer shall be adapted to different types of tourist, taking into consideration some aspects as tourists’ behavior, the type of tourism they prefer and, most of all, the culture they belong to and the culture of the people from the place they visit.

We face a number of legal and ethical issues in our work as scientists and as AGU members. To uphold the highest ethical standards in our professional activities, the Council has adopted policies on free access to published material, ethics in publishing, and misconduct in science. But what about guidelines to govern the personal behavior that constitutes harassment, sexual or otherwise?For years the AGU headquarters staff has had a policy that offers protection from harassment and rules for dealing with it, but the membership went without one until 1994. That year the Council adopted a policy that extends to the membership as well as to the staff and the vendors they encounter at meetings. The law only requires a policy to prevent harassment in the workplace, but the Council felt that a harassment policy was particularly important for members because the subtle behavior that can constitute harassment is most likely to occur at events that combine work and social interaction, such as the meetings, conferences, and training seminars that AGU members attend.

This paper describes the background for, realisation of and author reflections on a network workshop held at ESERA2013. As a new research area in science education, networks offer a unique opportunity to visualise and find patterns and relationships in complicated social or academic network data...... research community. With this workshop, participants were offered a way into network science based on authentic educational research data. The workshop was constructed as an inquiry lesson with emphasis on user autonomy. Learning activities had participants choose to work with one of two cases of networks...... network methodology in one’s research might supersede the perceived benefits of doing so. As a response to that problem, we argue that workshops can act as a road towards meaningful engagement with networks and highlight that network methodology promises new ways of interpreting data to answer questions...

Full Text Available Reactive oxygen species (ROS are generated by sperm metabolism. While, ROS are required for maturation, capacitation and acrosome reaction, they also modify many peroxidable cellular compounds. There is production of ROS during cryopreservation and frozen spermatozoa are highly sensitive to lipid peroxidation (LPO. Antioxidants exert a protective effect on the plasma membrane of frozen bovine sperm preserving both metabolic activity and cellular viability. Manganese (Mn++ is proved to be a chain breaking antioxidant in biological system. Therefore, we examined the role of (Mn++ during cryopreservation of cattle bull semen. Semen was divided into four parts and cryopreserved in egg-yolk-citrate extender + glycerol (EYC-G, EYC-G + 100 µM of Mn++, EYC-G + 150 µM of Mn++ and EYC-G + 200 µM of Mn++. After four hours of cooling and 24 hrs of freezing, the spermatozoa were examined for percentage motility, Hypo-osmotic swelling (HOS, LPO and protein leakage. Addition of manganese to the semen during cryopreservation showed a protective effect and accounted for an increase in semen quality parameters [percentage motility, HOS percent and decrease in malondialdehyde (MDA production and protein leakage]. The effect of manganese on motility and HOS was non-significant (p < 0.05 in cooled spermatozoa but significant with 150 µM of Mn++ in frozen-thawed spermatozoa. MDA production and protein leakage decreased to a significant and maximum level (p < 0.05 on addition of 200 µM of manganese. The addition of manganese to EYC-G dilutor will improve the quality/fertility of semen, which will result in improvement of in vitro fertilization and artificial insemination success rate.

Although the area of International Manufacturing Network (IMN) and International Operations Network (ION) has received considerable attention in the literature, most of studies appear multifaceted and interdisciplinary, and thereby require thorough investigation from both academic and practical perspectives, in order to deepen our related understanding. The book seeks advanced contributions that will combine theoretical insights and empirical experience by offering a detailed examination of IMN and, further, ION from various perspectives. This book can be used as a reference material for scholarpractitioners, business executives, and university researchers who need to deepen their understanding on the importance and influence of IMN and ION as well as their development. The book is important because there are few reference/resource materials available related to IMN and ION.

Network analysis is on the rise across scientific disciplines because of its ability to reveal complex, and often emergent, patterns and dynamics. Nonetheless, a growing concern in network analysis is the use of limited data for constructing networks. This concern is strikingly relevant to ecology and conservation biology, where network analysis is used to infer connectivity across landscapes. In this context, movement among patches is the crucial parameter for interpreting connectivity but because of the difficulty of collecting reliable movement data, most network analysis proceeds with only indirect information on movement across landscapes rather than using observed movement to construct networks. Statistical models developed for social networks provide promising alternatives for landscape network construction because they can leverage limited movement information to predict linkages. Using two mark-recapture datasets on individual movement and connectivity across landscapes, we test whether commonly used network constructions for interpreting connectivity can predict actual linkages and network structure, and we contrast these approaches to social network models. We find that currently applied network constructions for assessing connectivity consistently, and substantially, overpredict actual connectivity, resulting in considerable overestimation of metapopulation lifetime. Furthermore, social network models provide accurate predictions of network structure, and can do so with remarkably limited data on movement. Social network models offer a flexible and powerful way for not only understanding the factors influencing connectivity but also for providing more reliable estimates of connectivity and metapopulation persistence in the face of limited data.

is concerned with how vacancy durations vary with firms' minimum wage offers and minimum job requirements (regarding education, skills, age, gender and earlier work experience). The empirical analysis is based on ten employer surveys carried out by the DGBAS on Taiwan during the period 1996-2006. We estimate...... logistic discrete hazard models with a rich set of job and firm characteristics as explanatory variables. The results show that vacancies associated with higher wage offers take, ceteris paribus, longer to be filled. The impact of firms' wage offers and credential requirements does not vary over...... the business cycle. However, firms vary their skills requirements over the business cycle: our empirical analysis shows that, for a given wage offer, requirements are stricter in recessions and downturns. Separating between reasons for posting vacancies turned out important in explaining differences in vacancy...

Full Text Available Currently there is considerable interest in the legislative debate around generic biological drugs or "biosimilars" in the EU and US due to the large, lucrative market that it offers to the industry. While some countries have issued a few regulatory guidelines as well as product specific requirements, there is no general consensus as to a single, simple mechanism similar to the bioequivalence determination that leads to approval of generic small molecules all over the world. The inherent complex nature of the molecules, along with complicated manufacturing and analytical techniques to characterize them make it difficult to rely on a single human pharmacokinetic study for assurance of safety and efficacy. In general, the concept of comparability has been used for evaluation of the currently approved "similar" biological where a step by step assessment on the quality, preclinical and clinical aspects is made. In India, the focus is primarily on the availability and affordability of life-saving drugs. In this context every product needs to be evaluated on its own merit irrespective of the innovator brand. The formation of the National Biotechnology Regulatory Authority may provide a step in the right direction for regulation of these complex molecules. However, in order to have an efficient machinery for initial approval and ongoing oversight with a country-specific focus, cooperation with international authorities for granting approvals and continuous risk-benefit review is essential. Several steps are still needed for India to be perceived as a country that leads the world in providing quality biological products.

Abstract: In this paper we construct an index of Initial Public Offerings (IPOX) which is isomorph to the Austrian Traded Index (ATX). Conjecturing that the ATX constitutes a good leading indicator for the IPOX, in a first step we predict the ATX using linear and neural network models. Second, we estimate the IPOX one day ahead based on observed ATX data. We compare the quality of this estimation to an IPOX forecast based on forecasted ATX values in a third step. Given the ATX forecasting met...

In many experimental setups in social-sciences, psychology and economy the subjects are requested to accept or dispense monetary compensation which is usually given in discrete units. Using computer and mathematical modeling we show that in the framework of studying the dynamics of acceptance of proposals in the ultimatum game, the long time dynamics of acceptance of offers in the game are completely different for discrete vs. continuous offers. For discrete values the dynamics follow an exponential behavior. However, for continuous offers the dynamics are described by a power-law. This is shown using an agent based computer simulation as well as by utilizing an analytical solution of a mean-field equation describing the model. These findings have implications to the design and interpretation of socio-economical experiments beyond the ultimatum game.

Adolescent idiopathic scoliosis (AIS), environment, exposome and epigenetics: a molecular perspective of postnatal normal spinal growth and the etiopathogenesis of AIS with consideration of a network approach and possible implications for medical therapy
Genetic factors are believed to play an important role in the etiology of adolescent idiopathic scoliosis (AIS). Discordant findings for monozygotic (MZ) twins with AIS show that environmental factors including different intrauterine environments are important in etiology, but what these environmental factors may be is unknown. Recent evidence for common chronic non-communicable diseases suggests epigenetic differences may underlie MZ twin discordance, and be the link between environmental factors and phenotypic differences. DNA methylation is one important epigenetic mechanism operating at the interface between genome and environment to regulate phenotypic plasticity with a complex regulation across the genome during the first decade of life. The word exposome refers to the totality of environmental exposures from conception onwards, comprising factors in external and internal environments. The word exposome is used here also in relation to physiologic and etiopathogenetic factors that affect normal spinal growth and may induce the deformity of AIS. In normal postnatal spinal growth we propose a new term and concept, physiologic growth-plate exposome for the normal processes particularly of the internal environments that may have epigenetic effects on growth plates of vertebrae. In AIS, we propose a new term and concept pathophysiologic scoliogenic exposome for the abnormal processes in molecular pathways particularly of the internal environment currently expressed as etiopathogenetic hypotheses; these are suggested to have deforming effects on the growth plates of vertebrae at cell, tissue, structure and/or organ levels that are considered to be epigenetic. New research is required for chromatin modifications including DNA methylation in AIS subjects and vertebral growth plates excised at surgery. In addition, consideration is needed for a possible network approach to etiopathogenesis by constructing AIS diseasomes. These approaches may lead through screening

The increasing penetration of wind generation in power systems to fulfil the ambitious European targets will make wind power producers to play an even more important role in the future power system. Wind power producers are being incentivized to participate in reserve markets to increase their revenue, since currently wind turbine/farm technologies allow them to provide ancillary services. Thus, wind power producers are to develop offering strategies for participation in both energy and reserve markets, accounting for market rules, while ensuring optimal revenue. We consider a proportional offering strategy to optimally decide upon participation in both markets by maximizing expected revenue from day-ahead decisions while accounting for estimated regulation costs for failing to provide the services. An evaluation of considering the same proportional splitting of energy and reserve in both day- ahead and balancing market is performed. A set of numerical examples illustrate the behavior of such strategy. An important conclusion is that the optimal split of the available wind power between energy and reserve strongly depends upon prices and penalties on both market trading floors.
The Design Considerations Handbook includes information and suggestions for the design of systems typical to nuclear facilities, information specific to various types of special facilities, and information useful to various design disciplines. The handbook is presented in two parts. Part 1, which addresses design considerations, includes two sections. The first addresses the design of systems typically used in nuclear facilities to control radiation or radioactive materials. Specifically, this part addresses the design of confinement systems and radiation protection and effluent monitoring systems. The second section of Part 1 addresses the design of special facilities (i.e., specific types of nonreactor nuclear facilities). The specific design considerations provided in this section were developed from review of DOE 6430.1A and are supplemented with specific suggestions and considerations from designers with experience designing and operating such facilities. Part 2 of the Design Considerations Handbook describes good practices and design principles that should be considered in specific design disciplines, such as mechanical systems and electrical systems. These good practices are based on specific experiences in the design of nuclear facilities by design engineers with related experience. This part of the Design Considerations Handbook contains five sections, each of which applies to a particular engineering discipline.
Robot Systems Technology Branch engineers at Johnson Space Center created the remotely controlled Robonaut for use as an additional "set of hands" in extravehicular activities (EVAs) and to allow exploration of environments that would be too dangerous or difficult for humans. One of the problems Robonaut developers encountered was that the robot s interface offered an extremely limited field of vision. Johnson robotics engineer, Darby Magruder, explained that the 40-degree field-of-view (FOV) in initial robotic prototypes provided very narrow tunnel vision, which posed difficulties for Robonaut operators trying to see the robot s surroundings. Because of the narrow FOV, NASA decided to reach out to the private sector for assistance. In addition to a wider FOV, NASA also desired higher resolution in a head-mounted display (HMD) with the added ability to capture and display video.

Telemedicine is the rapidly developing application of clinical medicine by telephone, the internet or other networks for the purpose of consulting, and on occasions carrying out examinations or medical procedures. Telemedicine may be as simple as two health professionals discussing a case over the telephone, or as complex as using satellite technology and video-conferencing equipment to conduct a real-time consultation between medical specialists in two different countries. Telemedicine offers real benefits in a country as vast as India where the majority of the population lives in remote areas with no access to even the most basic healthcare. As the practice of telemedicine spreads, maintaining standards, security and privacy, will be a challenge especially with regard to legal and regulatory measures and who will be held responsible if telemedicine-assisted surgery fails due to failure in connectivity? Is it the surgeon, the satellite provider or the software/hardware engineer? What is the legal status of telemedicine-based diagnosis and treatment? Other legal issues involve conflicting national laws and information piracy, the dangers of prescription drugs that are banned in one country but not in another and quacks who offer medical advice and prescribe drugs over the internet. This paper discusses some of the legal, ethical and social considerations in the Indian context.

For over four decades, it has been possible to offer prenatal diagnostic testing for fetal abnormalities. Prenatal testing is now available for a wide range of monogenic disorders as well as chromosomal abnormalities and should be provided within the ethical framework of informed consent and autonomous choice. However, there are no published guidelines for health professionals from varied disciplines who offer prenatal diagnosis (PND) in a range of possible settings including departments of maternity, obstetrics and clinical genetics. We used an Expert Group technique to develop a set of guidelines for provision of prenatal diagnostic services. Thirteen European health professionals, all experts in PND, participated in a workshop to develop the guidelines, which were then subjected to a wide consultation process. The objective of PND was defined as providing prenatal diagnostic testing services (for genetic conditions) that enable families to make informed choices consistent with their individual needs and values and which support them in dealing with the outcome of such testing. General principles, logistical considerations, clinical care and counselling topics are all described and are equally applicable to invasive and non-invasive testing. These guidelines provide a framework for ethical clinical care; however, they are flexible enough to enable practitioners to adapt them to their particular setting. Ideally, an individualised approach to each family is required to ensure autonomous choice and informed consent regarding prenatal diagnostic testing within the local ethical and legal framework.

The importance of managing networks and services is finally being accepted by both operators/service providers and HW/SW manufacturers. Standards are thus coming for managing solutions based on any new emerging technology. However standards and commercial solutions have different level of completeness and performance depending on the related managed technology. Thus, being real systems often composed of a mix of different technologies, the quality of their overall management is limited by the less mature and effective single technology management system. Today broadband networks can be seen as a layered structure including ATM, SDH and WDM optical layers. While the management of SDH is quite mature and significant results are reached for ATM management, the management of the WDM optical layer is still in its infancy. Therefore the WDM layer management is a critical factor in the development of the overall broadband network management. The paper, after few considerations on general public network management issues, presents some solutions currently under study for the WDM optical layer management. Although the improvement of the weaker single technology management system surely improves the quality of the overall layered network management, this is just one step along the path for optimizing it. The objective is in fact the integration of the single layer management systems into a global one, avoiding duplications and improving efficiency and effectiveness. The paper presents at the end some considerations about this topic that is rapidly getting hot because of the potential economical benefits such as integration can offer.

Full Text Available Abstract Background In recent years, a considerable amount of research effort has been directed to the analysis of biological networks with the availability of genome-scale networks of genes and/or proteins of an increasing number of organisms. A protein-protein interaction (PPI network is a particular biological network which represents physical interactions between pairs of proteins of an organism. Major research on PPI networks has focused on understanding the topological organization of PPI networks, evolution of PPI networks and identification of conserved subnetworks across different species, discovery of modules of interaction, use of PPI networks for functional annotation of uncharacterized proteins, and improvement of the accuracy of currently available networks. Results In this article, we map known functional annotations of proteins onto a PPI network in order to identify frequently occurring interaction patterns in the functional space. We propose a new frequent pattern identification technique, PPISpan, adapted specifically for PPI networks from a well-known frequent subgraph identification method, gSpan. Existing module discovery techniques either look for specific clique-like highly interacting protein clusters or linear paths of interaction. However, our goal is different; instead of single clusters or pathways, we look for recurring functional interaction patterns in arbitrary topologies. We have applied PPISpan on PPI networks of Saccharomyces cerevisiae and identified a number of frequently occurring functional interaction patterns. Conclusion With the help of PPISpan, recurring functional interaction patterns in an organism's PPI network can be identified. Such an analysis offers a new perspective on the modular organization of PPI networks. The complete list of identified functional interaction patterns is available at http://bioserver.ceng.metu.edu.tr/PPISpan/.
Cellular operators are continuously densifying their networks to cope with the ever-increasing capacity demand. Furthermore, an extreme densification phase for cellular networks is foreseen to fulfill the ambitious fifth generation (5G) performance requirements. Network densification improves spectrum utilization and network capacity by shrinking base stations\\' (BSs) footprints and reusing the same spectrum more frequently over the spatial domain. However, network densification also increases the handover (HO) rate, which may diminish the capacity gains for mobile users due to HO delays. In highly dense 5G cellular networks, HO delays may neutralize or even negate the gains offered by network densification. In this paper, we present an analytical paradigm, based on stochastic geometry, to quantify the effect of HO delay on the average user rate in cellular networks. To this end, we propose a flexible handover scheme to reduce HO delay in case of highly dense cellular networks. This scheme allows skipping the HO procedure with some BSs along users\\' trajectories. The performance evaluation and testing of this scheme for only single HO skipping shows considerable gains in many practical scenarios. © 2016 IEEE.

Recent works have developed models that exploit the intrinsic geometry of manifolds and graphs, namely the Graph Neural Networks (GNNs) and its spectral variants, which learn from the local metric tensor via the Laplacian operator. Despite offering excellent sample complexity and built-in invariances, intrinsic geometry alone is invariant to isometr...

In this talk, we will describe the lessons learned based on processing and generating a decade of gridded AIRS and MODIS IR sounding data. We describe the challenges faced in accessing and sharing very large data sets, maintaining data provenance under evolving technologies, obtaining access to legacy calibration data and the permanent preservation of Earth science data records for on demand services. These lessons suggest a new approach to data stewardship will be required for the next decade of hyper spectral instruments combined with cloud resolving models. It will not be sufficient for stewards of future data centers to just provide the public with access to archived data but our experience indicates that data needs to reside close to computers with ultra large disc farms and tens of thousands of processors to deliver complex services on demand over very high speed networks much like the offerings of search engines today. Over the first decade of the 21st century, petabyte data records were acquired from the AIRS instrument on Aqua and the MODIS instrument on Aqua and Terra. NOAA data centers also maintain petabytes of operational IR sounders collected over the past four decades. The UMBC Multicore Computational Center (MC2) developed a Service Oriented Atmospheric Radiance gridding system (SOAR) to allow users to select IR sounding instruments from multiple archives and choose space-time- spectral periods of Level 1B data to download, grid, visualize and analyze on demand. Providing this service requires high data rate bandwidth access to the on line disks at Goddard. After 10 years, cost effective disk storage technology finally caught up with the MODIS data volume making it possible for Level 1B MODIS data to be available on line. However, 10Ge fiber optic networks to access large volumes of data are still not available from CSFC to serve the broader community. Data transfer rates are well below 10MB/s limiting their usefulness for climate studies. During

Full Text Available Epigenetics has attracted considerable attention with respect to its potential value in many areas of agricultural production, particularly under conditions where the environment can be manipulated or natural variation exists. Here we introduce key concepts and definitions of epigenetic mechanisms, including DNA methylation, histone modifications and non-coding RNA, review the current understanding of epigenetics in both fish and shellfish, and propose key areas of aquaculture where epigenetics could be applied. The first key area is environmental manipulation, where the intention is to induce an ‘epigenetic memory’ either within or between generations to produce a desired phenotype. The second key area is epigenetic selection, which, alone or combined with genetic selection, may increase the reliability of producing animals with desired phenotypes. Based on aspects of life history and husbandry practices in aquaculture species, the application of epigenetic knowledge could significantly affect the productivity and sustainability of aquaculture practices. Conversely, clarifying the role of epigenetic mechanisms in aquaculture species may upend traditional assumptions about selection practices. Ultimately, there are still many unanswered questions regarding how epigenetic mechanisms might be leveraged in aquaculture.

We propose a shift from the current paradigm of electricity markets treating stochastic producers similarly to conventional ones in terms of their offers. We argue that the producers’ offers should be probabilistic to reflect the limited predictability of renewable energy generation, while we...... should design market mechanisms to accommodate such offers. We argue that the transition from deterministic offers is a natural next step in electricity markets, by analytically proving our proposal’s equivalence with a two-price conventional market....

Implementation of Directed Self-Assembly (DSA) as a viable lithographic technology for high volume manufacturing will require significant efforts to co-optimize the DSA process options and constraints with existing work flows. These work flows include established etch stacks, integration schemes, and design layout principles. The two foremost patterning schemes for DSA, chemoepitaxy and graphoepitaxy, each have their own advantages and disadvantages. Chemoepitaxy is well suited for regular repeating patterns, but has challenges when non-periodic design elements are required. As the line-space polystyrene-block-polymethylmethacrylate chemoepitaxy DSA processes mature, considerable progress has been made on reducing the density of topological (dislocation and disclination) defects but little is known about the existence of 3D buried defects and their subsequent pattern transfer to underlayers. In this paper, we highlight the emergence of a specific type of buried bridging defect within our two 28 nm pitch DSA flows and summarize our efforts to characterize and eliminate the buried defects using process, materials, and plasma-etch optimization. We also discuss how the optimization and removal of the buried defects impacts both the process window and pitch multiplication, facilitates measurement of the pattern roughness rectification, and demonstrate hard-mask open within a back-end-of-line integration flow. Finally, since graphoepitaxy has intrinsic benefits in terms of design flexibility when compared to chemoepitaxy, we highlight our initial investigations on implementing high-chi block copolymer patterning using multiple graphoepitaxy flows to realize sub-20 nm pitch line-space patterns and discuss the benefits of using high-chi block copolymers for roughness reduction.

Airlines shape their route network by defining their routes through supply and demand considerations, paying little attention to network performance indicators, such as network robustness. However, the collapse of an airline network can produce high financial costs for the airline and all its geographical area of influence. The aim of this study is to analyze the topology and robustness of the network route of airlines following Low Cost Carriers (LCCs) and Full Service Carriers (FSCs) business models. Results show that FSC hubs are more central than LCC bases in their route network. As a result, LCC route networks are more robust than FSC networks.
This paper, which seeks to address the issue of justification in radiology, intends firstly to comment on the current discussion of the ethical foundation of radiological practice that focuses on the move from utilitarianism to the rights-centred criterion. Secondly, and this constitutes the bulk of the paper, it aims to offer a philosophical perspective, which is hoped will lead to a consideration of certain specific areas in ethical decision-making in the attempts here to deal with the main issue of justification in radiology.

Whether a doctor, professional baseball manager, or a politician, having successful negotiation skills is a critical part of being a leader. Building upon prior journal articles on negotiation strategy, the author presents the concept of the multiple equivalent simultaneous offer (MESO). The concept of a MESO is straightforward: as opposed to making a single offer, make multiple offers with several variables. Each offer alters the different variables, such that the end result of each offer is equivalent from the perspective of the party making the offer. Research has found several advantages to the use of MESOs. For example, using MESOs, an offer was more likely to be accepted, and the counterparty was more likely to be satisfied with the negotiated deal. Additional benefits have been documented as well, underscoring why a prepared radiology business leader should understand the theory and practice of MESO.

Full Text Available The Internet has forced most companies to consider online brand building strategies. This strategic consideration depends on the determination of the status quo of the brand at present. The former is crucial as identified success drivers of online brand initiatives are neither uniformly nor generically applicable to all online brand offerings. It is thus suggested that the applicability of success factors to online brand offerings depends on the appropriateness of the brand’s context, which in turn is determined by benchmarking the brand against categorised characteristics of existing online brands. This paper summarises and categorises South African online brand offerings over a three year period and applies the findings for elucidatory purposes to a three dimensional Brandscape Model. After managerial implications have been discussed, the study concludes with recommendations for future research.

To determine how the characteristics of the health benefits offered by employers affect worker insurance coverage decisions. The 1996-1997 and the 1998-1999 rounds of the nationally representative Community Tracking Study Household Survey. We use multinomial logistic regression to analyze the choice between own-employer coverage, alternative source coverage, and no coverage among employees offered health insurance by their employer. The key explanatory variables are the types of health plans offered and the net premium offered. The models include controls for personal, health plan, and job characteristics. When an employer offers only a health maintenance organization married employees are more likely to decline coverage from their employer and take-up another offer (odds ratio (OR)=1.27, pemployer and less likely to be uninsured (OR=0.650, pemployer and remaining uninsured for both married (OR=1.023, pemployer offers affects whether its employees take-up insurance, but has a smaller effect on overall coverage rates for workers and their families because of the availability of alternative sources of coverage. Relative to offering only a non-HMO plan, employers offering only an HMO may reduce take-up among those with alternative sources of coverage, but increase take-up among those who would otherwise go uninsured. By modeling the possibility of take-up through the health insurance offers from the employer of the spouse, the decline in coverage rates from higher net premiums is less than previous estimates.

Neural networks, especially in nonlinear system identification and control applications, are typically considered to be black-boxes which are difficult to analyze and understand mathematically. Due to this reason, an in- depth mathematical analysis offering insight into the different neural network transformation layers based on a theoretical transformation scheme is desired, but up to now neither available nor known. In previous works it has been shown how proven engineering methods such as dimensional analysis and the Laplace transform may be used to construct a neural controller topology for time-invariant systems. Using the knowledge of neural correspondences of these two classical methods, the internal nodes of the network could also be successfully interpreted after training. As further extension to these works, the paper describes the latest of a theoretical interpretation framework describing the neural network transformation sequences in nonlinear system identification and control. This can be achieved By incorporation of the method of exact input-output linearization in the above mentioned two transform sequences of dimensional analysis and the Laplace transformation. Based on these three theoretical considerations neural network topologies may be designed in special situations by pure translation in the sense of a structural compilation of the known classical solutions into their correspondent neural topology. Based on known exemplary results, the paper synthesizes the proposed approach into the visionary goals of a structural compiler for neural networks. This structural compiler for neural networks is intended to automatically convert classical control formulations into their equivalent neural network structure based on the principles of equivalence between formula and operator, and operator and structure which are discussed in detail in this work.

Regulatory decisions regarding attention deficit hyperactivity disorder drug licensing and labelling, along with recent statements from professional associations, raise questions of practice regarding the evaluation and treatment of patients with attention deficit hyperactivity disorder. To address these issues for the European community, the European Network for Hyperkinetic Disorders, through its European Attention Deficit Hyperactivity Disorder Guidelines Group, organised a meeting between attention deficit hyperactivity disorder specialists, paediatric cardiovascular specialists, and representatives of the major market authorisation holders for attention deficit hyperactivity disorder medications. This manuscript represents their consensus on cardiovascular aspects of attention deficit hyperactivity disorder medications. Although sudden death has been identified in multiple young individuals on attention deficit hyperactivity disorder medication causing regulatory concern, when analysed for exposure using currently available data, sudden death does not appear to exceed that of the general population. There is no current evidence to suggest an incremental benefit to electrocardiography assessment of the general attention deficit hyperactivity disorder patient. Congenital heart disease patients have an increased prevalence of attention deficit hyperactivity disorder, and can benefit from attention deficit hyperactivity disorder therapies, including medication. The attention deficit hyperactivity disorder specialist is the appropriate individual to evaluate benefit and risk and recommend therapy in all patients, although discussion with a heart specialist is reasonable for congenital heart disease patients. For attention deficit hyperactivity disorder patients with suspected heart disease or risk factor/s for sudden death, assessment by a heart specialist is recommended, as would also be the case for a non-attention deficit hyperactivity disorder patient.

Network coevolution, the process of network topology evolution in feedback with dynamical processes over the network nodes, is a common feature of many engineered and natural networks. In such settings, the change in network topology occurs at a comparable time scale to nodal dynamics. Coevolutionary modeling offers the possibility to better understand how and why network structures emerge. For example, social networks can exhibit a variety of structures, ranging from almost uniform to scale-free degree distributions. While current models of network formation can reproduce these structures, coevolutionary modeling can offer a better understanding of the underlying dynamics. This paper presents an overview of recent work on coevolutionary models of network formation, with an emphasis on the following three settings: (i) dynamic flow of benefits and costs, (ii) transient link establishment costs, and (iii) latent preferential attachment.

The CERN IT department has built over the years a performant and integrated ecosystem of collaboration tools, from videoconference and webcast services to event management software. These services have been designed and evolved in very close collaboration with the various communities surrounding the laboratory and have been massively adopted by CERN users. To cope with this very heavy usage, global infrastructures have been deployed which take full advantage of CERN's international and global nature. If these services and tools are instrumental in enabling the worldwide collaboration which generates major HEP breakthroughs, they would certainly also benefit other sectors of science in which globalization has already taken place. Some of these services are driven by commercial software (Vidyo or Wowza for example), some others have been developed internally and have already been made available to the world as Open Source Software in line with CERN's spirit and mission. Indico for example is now installed in 100+ institutes worldwide. But providing the software is often not enough and institutes, collaborations and project teams do not always possess the expertise, or human or material resources that are needed to set up and maintain such services. Regional and national institutions have to answer needs, which are growingly global and often contradict their operational capabilities or organizational mandate and so are looking at existing worldwide service offers such as CERN's. We believe that the accumulated experience obtained through the operation of a large scale worldwide collaboration service combined with CERN's global network and its recently- deployed Agile Infrastructure would allow the Organization to set up and operate collaborative services, such as Indico and Vidyo, at a much larger scale and on behalf of worldwide research and education institutions and thus answer these pressing demands while optimizing resources at a global level. Such services would

Full Text Available The importance of healthy diet from the earliest age as well as its influence on human health is indisputable. Unbalanced diet in childhood can, along with unhealthy lifestyle (stress, smoking, physical inactivity, cause a number of diseases at a later age. Two week menus in 26 kindergartens from continental and coastal Croatia have been analysed, taking into consideration the type of kindergarten (public, private, or religious. The aim of this research is to determine the quality of the offer regarding the intake of milk and dairy products, which, regarding their bioavailability, represent a major source of calcium, an essential nutrient in the intensive growth phase of children and young people. Using basic statistics, significant differences were not determined neither in the regional offer of milk and dairy products in the different types of kindergartens nor in the content of calcium and phosphorus. Milk and dairy products were adequately represented in the weekly offer in both regions under observation, and the average offer contained 9.7±1.5 servings. Average content of calcium in daily menues is 714.5±235.9 mg, which is in agreement with dietary reference intake recommendations (300-800 mg and Croatian recommendations (400-700 mg. Use of fuzzy logic in creating new daily menus, by combining the existing offers enabled significant enlargement of the set of nutritionally acceptable menus as well as a greater diversity of meals.
Criminal offenders may be offered to participate in voluntary rehabilitation programs aiming at correcting undesirable behaviour, as a condition of early release. Behavioural treatment may include direct intervention into the central nervous system (CNS). This article discusses under which circumstances voluntary rehabilitation by CNS intervention is justified. It is argued that although the context of voluntary rehabilitation is a coercive circumstance, consent may still be effective, in the sense that it can meet formal criteria for informed consent. Further, for a consent to be normatively valid ("take the wronging out of the act") under a coercive circumstance, the subject to be treated must (1) have the sovereign authority to consent, and (2) the offer-giver must be in the right normative position to make the offer. While I argue that subjects do have the sovereign authority to consent to treatment, I also argue that inappropriate offers yield invalid consents. Considerations on inappropriate offers should therefore inform which kinds of CNS intervention-based rehabilitation schemes the state may propose as part of the criminal justice system. Yet as I conclude in this paper, while there are some intrinsic constraints on voluntary rehabilitation programs, the main constraints on voluntary rehabilitation are likely to be contingent overriders. However, CNS intervention is not ruled out as such in the context of voluntary rehabilitation.

Full Text Available In the competitive business environment, as the number of rational consumers faced with many choices increases, companies can achieve their dominance best by applying the business concepts oriented to consumers in order to deliver a value which is different and better than that of their competitors. Among the various products on the market, an educated consumer chooses the offer that provides the greatest value for him/her. Therefore, it is essential for each company to determine how consumers perceive the value of its offer, and which factors determine the high level of perceived value for current and potential consumers. An analysis of these factors provides guidance on how to improve the existing offer and what the offer to be delivered in the future should be like. That could increase the perceived value of the company offer and result in a positive impact on consumer satisfaction and on establishing a stronger, longterm relationship with consumers. The process of defining the perceived value of a particular market offer is affected by the factors of the respective company’s offer as well as by competition factors, consumer factors and buying process factors. The aim of this paper is to analyze the relevant knowledge about the process of creating the perceived value of the company’s market offer and the factors that influence this process. The paper presents a conceptual model of the perceived value creation process in consumers’ mind.

Full Text Available This article deals with the approach to interpretation of essence of the network community concept in which we propose to consider it as a new form of social organization that is substantiated by the specificity of how our society is functioning in conditions of Postmodern. There were explored two main approaches to network communities studying: the first approach considers social networks in a classic, traditional interpretation of modernity as a special kind of social structure, and the second one represents social networks as a specific virtual formation, a social structure of virtual Internet reality. There were revealed some common features of a social organization and a network community: presence of permanent communication between members of the group, united by certain common interests and goals, as well as presence of the certain hierarchy among all members of the community, and the rules of conduct, implementation of communication. Distinctive features: network community is more informal, offers its members considerable leeway in the implementation of their own goals and satisfying the needs, full virtualization of communication absence of direct interaction during communication, under conditions where the main resource for the interchange in network communities is information. It was shown that in the process of emergence, development and distribution of network communities, the fundamental role is played by modern communications - namely, unification them in a stable set of interconnected networks and, in particular network communities.

Full Text Available Software-Defined Networking-based Mobile Networks (SDN-MNs are considered the future of 5G mobile network architecture. With the evolving cyber-attack threat, security assessments need to be performed in the network management. Due to the distinctive features of SDN-MNs, such as their dynamic nature and complexity, traditional network security assessment methodologies cannot be applied directly to SDN-MNs, and a novel security assessment methodology is needed. In this paper, an effective security assessment mechanism based on attack graphs and an Analytic Hierarchy Process (AHP is proposed for SDN-MNs. Firstly, this paper discusses the security assessment problem of SDN-MNs and proposes a methodology using attack graphs and AHP. Secondly, to address the diversity and complexity of SDN-MNs, a novel attack graph definition and attack graph generation algorithm are proposed. In order to quantify security levels, the Node Minimal Effort (NME is defined to quantify attack cost and derive system security levels based on NME. Thirdly, to calculate the NME of an attack graph that takes the dynamic factors of SDN-MN into consideration, we use AHP integrated with the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS as the methodology. Finally, we offer a case study to validate the proposed methodology. The case study and evaluation show the advantages of the proposed security assessment mechanism.

Full Text Available In order to keep the price down, a purchaser sends out the request for quotation to a group of suppliers in a supply chain network. The purchaser will then choose a supplier with the best combination of price and quality. A potential supplier will try to collect the related information about other suppliers so he/she can offer the best bid to the purchaser. Therefore, confidentiality becomes an important consideration for the design of a supply chain network. Chen et al. have proposed the application of the Bell-LaPadula model in the design of a secured supply chain network. In the Bell-LaPadula model, a subject can be in one of different security clearances and an object can be in one of various security classifications. All the possible combinations of (Security Clearance, Classification pair in the Bell-LaPadula model can be thought as different states in the Markov Chain model. This paper extends the work done by Chen et al., provides more details on the Markov Chain model and illustrates how to use it to monitor the security state transition in the supply chain network.

To assess the current attitudes of extracorporeal membrane oxygenation (ECMO) program directors regarding eligibility for ECMO among children with cardiopulmonary failure. Electronic cross-sectional survey of ECMO program directors at ECMO centers worldwide within the Extracorporeal Life Support Organization directory (October 2015-December 2015). Of 733 eligible respondents, 226 (31%) completed the survey, 65% of whom routinely cared for pediatric patients. There was wide variability in whether respondents would offer ECMO to any of the 5 scenario patients, ranging from 31% who would offer ECMO to a child with trisomy 18 to 76% who would offer ECMO to a child with prolonged cardiac arrest and indeterminate neurologic status. Even physicians practicing the same specialty sometimes held widely divergent opinions, with 50% of pediatric intensivists stating they would offer ECMO to a child with severe developmental delay and 50% stating they would not. Factors such as quality of life and neurologic status influenced decision making and were used to support decisions for and against offering ECMO. ECMO program directors vary widely in whether they would offer ECMO to various children with cardiopulmonary failure. This heterogeneity in physician decision making underscores the need for more evidence that could eventually inform interinstitutional guidelines regarding patient selection for ECMO.

This study assesses the availability of websites offering to sell psilocybin spores and psilocybin, a powerful hallucinogen contained in Psilocybe mushrooms. Over a 25-month period beginning in March 2003, eight searches were conducted in Google using the term "psilocybin spores." In each search the first 100 nonsponsored links obtained were scored by two independent raters according to standardized criteria to determine whether they offered to sell psilocybin or psilocybin spores. No attempts were made to procure the products offered for sale in order to ascertain whether the marketed psilocybin was in fact "genuine" or "counterfeit." Of the 800 links examined, 58% led to websites offering to sell psilocybin spores. Additionally, evidence that whole Psilocybe mushrooms are offered for sale online was obtained. Psilocybin and psilocybin spores were found to be widely available for sale over the Internet. Online purchase of psilocybin may facilitate illicit use of this potent psychoactive substance. Additional studies are needed to assess whether websites offering to sell psilocybin and psilocybin spores actually deliver their products as advertised.
Full Text Available Due to rapid development in the past decade, air transportation system has attracted considerable research attention from diverse communities. While most of the previous studies focused on airline networks, here we systematically explore the robustness of the Chinese air route network, and identify the vital edges which form the backbone of Chinese air transportation system. Specifically, we employ a memetic algorithm to minimize the network robustness after removing certain edges, and hence the solution of this model is the set of vital edges. Counterintuitively, our results show that the most vital edges are not necessarily the edges of the highest topological importance, for which we provide an extensive explanation from the microscope view. Our findings also offer new insights to understanding and optimizing other real-world network systems.

Full Text Available One of the main critical success factors for the companies is their ability to build and maintain an effective collaborative network. This is more critical in the IT industry where the development of sustainable competitive advantage requires an integration of various resources, platforms, and capabilities provided by various actors. Employing such a collaborative network will dramatically change the operations management and promote flexibility and agility. Despite its importance, there is a lack of an analytical tool on collaborative network building process. In this paper, we propose an optimization model employing AHP and multiobjective programming for collaborative network building process based on two interorganizational relationships’ theories, namely, (i transaction cost theory and (ii resource-based view, which are representative of short-term and long-term considerations. The five different methods were employed to solve the formulation and their performances were compared. The model is implemented in an IT company who was in process of developing a large-scale enterprise resource planning (ERP system. The results show that the collaborative network formed through this selection process was more efficient in terms of cost, time, and development speed. The framework offers novel theoretical underpinning and analytical solutions and can be used as an effective tool in selecting network alternatives.
Probabilistic Boolean network (PBN) modelling is a semi-quantitative approach widely used for the study of the topology and dynamic aspects of biological systems. The combined use of rule-based representation and probability makes PBN appealing for large-scale modelling of biological networks where degrees of uncertainty need to be considered. A considerable expansion of our knowledge in the field of theoretical research on PBN can be observed over the past few years, with a focus on network inference, network intervention and control. With respect to areas of applications, PBN is mainly used for the study of gene regulatory networks though with an increasing emergence in signal transduction, metabolic, and also physiological networks. At the same time, a number of computational tools, facilitating the modelling and analysis of PBNs, are continuously developed. A concise yet comprehensive review of the state-of-the-art on PBN modelling is offered in this article, including a comparative discussion on PBN versus similar models with respect to concepts and biomedical applications. Due to their many advantages, we consider PBN to stand as a suitable modelling framework for the description and analysis of complex biological systems, ranging from molecular to physiological levels.

When a deceased-donor kidney is offered to a waitlisted candidate, the decision to accept or decline the organ relies primarily upon a practitioner's experience and intuition. Such decisions must achieve a delicate balance between estimating the immediate benefit of transplantation and the potential for future higher-quality offers. However, the current experience-based paradigm lacks scientific rigor and is subject to the inaccuracies that plague anecdotal decision-making. A data-driven analytics-based model was developed to predict whether a patient will receive an offer for a deceased-donor kidney at Kidney Donor Profile Index thresholds of 0.2, 0.4, and 0.6, and at timeframes of 3, 6, and 12 months. The model accounted for Organ Procurement Organization, blood group, wait time, DR antigens, and prior offer history to provide accurate and personalized predictions. Performance was evaluated on data sets spanning various lengths of time to understand the adaptability of the method. Using United Network for Organ Sharing match-run data from March 2007 to June 2013, out-of-sample area under the receiver operating characteristic curve was approximately 0.87 for all Kidney Donor Profile Index thresholds and timeframes considered for the 10 most populous Organ Procurement Organizations. As more data becomes available, area under the receiver operating characteristic curve values increase and subsequently level off. The development of a data-driven analytics-based model may assist transplant practitioners and candidates during the complex decision of whether to accept or forgo a current kidney offer in anticipation of a future high-quality offer. The latter holds promise to facilitate timely transplantation and optimize the efficiency of allocation.
Full Text Available The following paper aims to assess investor reaction to mandatory offers on the Warsaw Stock Exchange, which is important because knowledge about these reactions can be used to make better investment decisions. This paper highlights the importance of procedure in making a mandatory offer and its grounds in the Polish legal system. Additionally, it presents empirical research on the reactions of investors to mandatory offers on the Warsaw Stock Exchange. It has been provided that mandatory offers have a significant impact on the price of a company’s shares listed on the Warsaw Stock Exchange. Knowledge about the reactions of investors to a mandatory offer may be used when selecting securities for an investment portfolio. The findings may provide guidance in deciding whether to begin or end investment in the company, both for individual and institutional investors. The event study methodology approach used in the paper is regarded as valuable and can be the basis for further research in other areas of the capital market research, especially in the context of information efficiency.

This book focuses on the emerging research topic "green (energy efficient) wireless networks" which has drawn huge attention recently from both academia and industry. This topic is highly motivated due to important environmental, financial, and quality-of-experience (QoE) considerations. Specifically, the high energy consumption of the wireless networks manifests in approximately 2% of all CO2 emissions worldwide. This book presents the authors’ visions and solutions for deployment of energy efficient (green) heterogeneous wireless communication networks. The book consists of three major parts. The first part provides an introduction to the "green networks" concept, the second part targets the green multi-homing resource allocation problem, and the third chapter presents a novel deployment of device-to-device (D2D) communications and its successful integration in Heterogeneous Networks (HetNets). The book is novel in that it specifically targets green networking in a heterogeneous wireless medium, which re...

This paper investigates why all-inclusive travel packages are offered at some hotels but not at others. By using the theory of transaction cost, it is argued that all-inclusive contracts mitigate a hold-up problem and that the severity of this problem varies with regards to the hotel’s distance to the resort center. This hypothesis is tested empirically against data from 3798 hotel offers and is strongly supported. Additionally, some country-specific mechanisms related to the general price le...

Donation after circulatory determination of death (DCDD) has the potential to increase the number of organs available for transplantation. Because consent and management of potential donors must occur before death, DCDD raises unique ethical and policy issues. To develop an ethics and health policy statement on adult and pediatric DCDD relevant to critical care and transplantation stakeholders. A multidisciplinary panel of stakeholders was convened to develop an ethics and health policy statement. The panel consisted of representatives from the American Thoracic Society, Society of Critical Care Medicine, International Society for Heart and Lung Transplantation, Association of Organ Procurement Organizations, and the United Network of Organ Sharing. The panel reviewed the literature, discussed important ethics and health policy considerations, and developed a guiding framework for decision making by stakeholders. A framework to guide ethics and health policy statement was established, which addressed the consent process, pre- and post mortem interventions, the determination of death, provisions of end-of-life care, and pediatric DCDD. The information presented in this Statement is based on the current evidence, experience, and clinical rationale. New clinical research and the development and dissemination of new technologies will eventually necessitate an update of this Statement.

Full Text Available Knowledge is a vital intangible asset for any organization and cannot be valued exactly due its special form of materialization. Although we have this drawback, a scientifically established value should be used in order to measure the performance of knowledge holders. A correct valuation helps to know the worth of assets offered in exploitation. Exploitation of this resource could be done in several different ways, but integration in knowledge networks seems to generate best efficiency ratio. Networks offer the possibility to change information, to obtain new information, to build further ideas arose from network partners or to develop together new ideas. Thus, networks assure conditions to optimize the members’ knowledge portfolios. Optimization of knowledge usage creates benefits for network members. These benefits could be profits (if members are private companies or social welfare (if members are looking after collective purposes. Taxonomy of knowledge networks is diverse, permitting an adaptation to the needs of members. Networks permit a large scale of heterogeneity. Since an important part of new knowledge creating costs is covered from public budgetary resources, a special development is recorded at those networks which are exclusively or partly organized in the public sector or benefit by participation from the public sector.

Purpose To further our insight into the role of networks in health system reform, the purpose of this paper is to investigate how one agency, the NSW Agency for Clinical Innovation (ACI), and the multiple networks and enabling resources that it encompasses, govern, manage and extend the potential of networks for healthcare practice improvement. Design/methodology/approach This is a case study investigation which took place over ten months through the first author's participation in network activities and discussions with the agency's staff about their main objectives, challenges and achievements, and with selected services around the state of New South Wales to understand the agency's implementation and large system transformation activities. Findings The paper demonstrates that ACI accommodates multiple networks whose oversight structures, self-organisation and systems change approaches combined in dynamic ways, effectively yield a diversity of network governances. Further, ACI bears out a paradox of "centralised decentralisation", co-locating agents of innovation with networks of implementation and evaluation expertise. This arrangement strengthens and legitimates the role of the strategic hybrid - the healthcare professional in pursuit of change and improvement, and enhances their influence and impact on the wider system. Research limitations/implications While focussing the case study on one agency only, this study is unique as it highlights inter-network connections. Contributing to the literature on network governance, this paper identifies ACI as a "network of networks" through which resources, expectations and stakeholder dynamics are dynamically and flexibly mediated and enhanced. Practical implications The co-location of and dynamic interaction among clinical networks may create synergies among networks, nurture "strategic hybrids", and enhance the impact of network activities on health system reform. Social implications Network governance requires more

Research into the methods which caregivers use to encourage children to eat vegetables is limited, with minimal evidence about what the barriers are to offering these foods. Vegetable consumption in children is typically low, and so gaining information on these factors is vital in order to develop further caregiver-centred interventions to increase children's vegetable consumption. This study aimed to investigate the methods caregivers use to offer vegetables to preschool aged children, as well as the factors which influence whether and how caregivers present vegetables to their children. Seventeen caregivers with a preschool aged child participated in focus groups to assess these questions. Thematic analysis indicated that caregivers use a range of methods to offer their children vegetables, with these methods falling into three broad categories: behavioural/active methods, passive methods and food manipulations. Influences on caregiver offering which emerged from the focus groups formed four categories: information, cost, parent factors and child factors. Together with large-scale quantitative data, this information can be used to shape future interventions aiming to increase children's vegetable intake as well as to tailor advice given to caregivers striving to achieve a healthful diet for their children. © 2016 John Wiley & Sons Ltd.

Full Text Available Investments into communications mix are specific because besides significant financial resources it also involves creative marketing ideas that are a result of imagination and experience. However, the application of direct marketing communication mix is like 'a cave on iceberg'. The visible aspect presented through promotional content is only a small part of the whole process including experts from different fields. The process of creation a new communication mix of direct marketing must fully use all the challenges posed by sophisticated technology. Direct marketing depicted by new technology (cable television, telemarketing and the Internet can substantially increase the competitive advantage of enterprises in attracting their customer's attention and creating their loyalty as well. The companies use the mentioned media more frequently in order to create such offers that will lead towards strengthening loyalty of the existing customers, while simultaneously attracting those customers who were previously making purchases with our direct competitors. Hence, an offer as a creatively designed marketing vehicle proposes a number of potential benefits to a client. However, the client will be able to claim those benefits only in the case when a customer takes action as suggested by a communicated message. Basically, those are 'the rules of the game' that regulate relationship between company and client in direct marketing. Creating offers which guide the process of direct marketing is in the domain of customer relations management. Without an attractive offer, consumers will not create any type of measurable response to a company and therefore relations with clients would never emerge. On the other hand, if a company fails to continuously follow client's needs and wants, those engaged in direct sales will not be able to create adequate offers that would satisfy clients and motivate them to repeat purchases. .

Adolescents who refuse direct cannabis offers and remain non-users represent a potentially very informative, yet surprisingly understudied group. We examined a range of risk and protective factors putatively associated with this poorly understood "cannabis-resilient" profile. Paper-and-pencil questionnaires assessing substance use, peer and family relations, and behavioral and personality characteristics were completed by 19,303 middle- and high-school students from 82 schools in Norway (response rate 84%) The lifetime prevalence of cannabis use was 7.6%. Another 10.4% reported no use of the drug despite having received recent cannabis offers. Results from the multinomial logistic regression revealed a set of characteristics differentiating adolescents who resisted such offers from those who: (a) neither received the offers nor used, and, more importantly, (b) used the drug. Specifically, parent-child relationship quality, negative drug-related beliefs, absence of close relationships with cannabis-users, low delinquency, no regular tobacco use, and infrequent alcohol intoxication were all associated with increased odds of being in the cannabis-resilient vs. cannabis-user group. This pattern of results was comparable across middle- and high-school cohorts, but the parent-child relationship quality and delinquency were significantly associated with cannabis-resilient vs. cannabis-use outcome only among younger and older adolescents, respectively. Among other low-risk characteristics, better relationships with parents and beliefs that drug use is problematic were associated with adolescents' refusals to accept cannabis offers. These results may have implications for novel preventive strategies targeting cannabis-exposed adolescents. Copyright © 2016. Published by Elsevier Ireland Ltd.

This article seeks to offer a systematic approach to establishing a reliable network of facilities in closed loop supply chains (CLSCs) under uncertainties. Facilities that are located in this article concurrently satisfy both traditional objective functions and reliability considerations in CLSC network designs. To attack this problem, a novel mathematical model is developed that integrates the network design decisions in both forward and reverse supply chain networks. The model also utilizes an effective reliability approach to find a robust network design. In order to make the results of this article more realistic, a CLSC for a case study in the iron and steel industry has been explored. The considered CLSC is multi-echelon, multi-facility, multi-product and multi-supplier. Furthermore, multiple facilities exist in the reverse logistics network leading to high complexities. Since the collection centres play an important role in this network, the reliability concept of these facilities is taken into consideration. To solve the proposed model, a novel interactive hybrid solution methodology is developed by combining a number of efficient solution approaches from the recent literature. The proposed solution methodology is a bi-objective interval fuzzy possibilistic chance-constraint mixed integer linear programming (BOIFPCCMILP). Finally, computational experiments are provided to demonstrate the applicability and suitability of the proposed model in a supply chain environment and to help decision makers facilitate their analyses.

Complex problems in science, business, and engineering typically require some tradeoff between exploitation of known solutions and exploration for novel ones, where, in many cases, information about known solutions can also disseminate among individual problem solvers through formal or informal networks. Prior research on complex problem solving by collectives has found the counterintuitive result that inefficient networks, meaning networks that disseminate information relatively slowly, can perform better than efficient networks for problems that require extended exploration. In this paper, we report on a series of 256 Web-based experiments in which groups of 16 individuals collectively solved a complex problem and shared information through different communication networks. As expected, we found that collective exploration improved average success over independent exploration because good solutions could diffuse through the network. In contrast to prior work, however, we found that efficient networks outperformed inefficient networks, even in a problem space with qualitative properties thought to favor inefficient networks. We explain this result in terms of individual-level explore-exploit decisions, which we find were influenced by the network structure as well as by strategic considerations and the relative payoff between maxima. We conclude by discussing implications for real-world problem solving and possible extensions.

The presence of the East Turkistan terrorist network in China can be traced back to the rebellions on the BAREN region in Xinjiang in April 1990. This article intends to research the East Turkistan networks in China and offer a panoramic view. The events, terrorists and their relationship are described using matrices. Then social network analysis is adopted to reveal the network type and the network structure characteristics. We also find the crucial terrorist leader. Ultimately, some results show that the East Turkistan network has big hub nodes and small shortest path, and that the network follows a pattern of small world network with hierarchical structure.

In these studies, college students served as confederates in a simple field experiment. They approached fellow college students of another gender and asked one of three questions: (a “Would you go out with me tonight?” (b “Would you come over to my apartment tonight?” or (c “Would you go to bed with me tonight?” Men and women differed markedly in their receptivity to casual sexual offers. When asked: “Would you go out with me tonight?” both were equally receptive. Yet, when confederates asked, “Would you come over to my apartment” or “Would you go to bed with me?” gender differences were striking. In the following series of experiments we attempted to develop a pencil and paper method to mirror the procedure of the classic study. We think we succeeded. Although cultural and social considerations may have influenced participants’ tendency to accept or reject sexual offers, as predicted by evolutionary perspectives, in all three experiments men were more likely than women to accept sexual offers. The studies also explored some of the reasons men and women gave for refusing a date, apartment visit, or a sexual encounter. We close by itemizing some questions that, given this new set of research materials, may be worth asking.

Full Text Available Faculty of Engineering Technology of the Open University of Sri Lanka has been offering engineering programmes at a distance for the last two decades or so. However, completion rates in Faculty of Engineering Technology are lower compared to the other faculties of the University. This paper investigates the reasons for low completion rates in the faculty and suggests ways and means to overcome this problem. The study concludes that increasing student numbers will not necessarily increase percentage of students completing the programme though the number of students completing is increased. It is found that students offering courses for the first time in the system of distance education in their academic career perform poorer because they are not conversant with distance education techniques. It is recommended that the Faculty must offer an orientation programme on distance education to all the students enrolling for the first time, before they commence their regular programmes. Further, it has been found that considerable percentage of students who obtain eligibility to sit the final examination by completing the continuous assessments do not sit the final examination. This has been found to contribute towards non-completion of programmes as students sitting the final examination in the subsequent years perform poorly in their exams. To overcome this problem, it is recommended that current practise of allowing the student to carry forward their eligibility to unlimited period of time must be disbanded.

Nursing injuries are alarmingly high in the healthcare system. The rate of injuries adds to the shortage of nurses that are already employed. Preventing nursing injuries has focused on utilizing patient handling equipment. This project used post offer pre employment testing to attempt to control the injuries of nurses in a healthcare facility. Injuries were significantly lower in the employment pool that was tested when compared the nursing staff that had not been tested. Five injuries were reported in the tested group, resulting in $1,778 spent on the injuries, whereas the non-tested group had 54 injuries totaling $26,208. The total return on investment by this program was $4,541,059. Post Offer Pre employment testing can be a cost effective way to decrease the amount of injuries with nursing staff.

Full Text Available After the launching of a Fundamentals of Physics course offered for different campuses of the National University of Colombia in blended learning mode, various experiences were collected in a virtual assessment that were supported 100% by ICT. We implemented an evaluation system that consists of different categories ranging from traditional examinations, partial examinations, final examinations, workshops, quizzes, attendance, and duties and forums, all evaluated online. In particular, random blocks of questions were used for examinations taken from large databases, built especially for this purpose, on the order of 100 per chapter. We comment on the results achieved with the implementation of the evaluation system proposed, in addition to the possibilities offered and the risks they present.
Full Text Available A bank loan is the main form of economical credit. It is for corporate activities â€“ for medium and big companies and for retail activities â€“ for small companies and individuals. The conditions for credit mainly depend on the quality of customers, it means their ability to perform a profitable activity and to be able to pay back the credits. For reasons which are mainly connected to marketing, bank practice has developed a large range of credit names, trying to emphasize some of the parts of the products or to take profit of some competition advantages in relation with customersâ€™ products. We are trying to include the offer of bank loans in a typology which takes into account the law, the bank field rules and the main technical features of the offered products.

To evaluate whether the support offered by maternity hospitals is associated with higher prevalences of exclusive and predominant breastfeeding. This is a cross-sectional study including a representative sample of 916 infants less than six months who were born in maternity hospitals, in Ribeirao Preto, Sao Paulo, Southeastern Brazil, 2011. The maternity hospitals were evaluated in relation to their fulfillment of the Ten Steps to Successful Breastfeeding. Data were collected regarding breastfeeding patterns, the birth hospital and other characteristics. The individualized effect of the study factor on exclusive and predominant breastfeeding was analyzed using Poisson multiple regression with robust variance. Predominant breastfeeding tended to be more prevalent when the number of fulfilled steps was higher (p of linear trend = 0.057). The step related to not offering artificial teats or pacifiers to breastfed infants and that related to encouraging the establishment of breastfeeding support groups were associated, respectively, to a higher prevalence of exclusive (PR = 1.26; 95%CI 1.04;1.54) and predominant breastfeeding (PR = 1.55; 95%CI 1.01;2.39), after an adjustment was performed for confounding variables. We observed a positive association between support offered by maternity hospitals and prevalences of exclusive and predominant breastfeeding. These results can be useful to other locations with similar characteristics (cities with hospitals that fulfill the Ten Steps to Successful Breastfeeding) to provide incentive to breastfeeding, by means of promoting, protecting and supporting breastfeeding in maternity hospitals.

Full Text Available Conflict between substitute decision makers (SDMs and health care providers in the intensive care unit is commonly related to goals of treatment at the end of life. Based on recent court decisions, even medical consensus that ongoing treatment is not clinically indicated cannot justify withdrawal of mechanical ventilation without consent from the SDM. Cardiopulmonary resuscitation (CPR, similar to mechanical ventilation, is a life-sustaining therapy that can result in disagreement between SDMs and clinicians. In contrast to mechanical ventilation, in cases for which CPR is judged by the medical team to not be clinically indicated, there is no explicit or case law in Canada that dictates that withholding/not offering of CPR requires the consent of SDMs. In such cases, physicians can ethically and legally not offer CPR, even against SDM or patient wishes. To ensure that nonclinically indicated CPR is not inappropriately performed, hospitals should consider developing ‘scope of treatment’ forms that make it clear that even if CPR is desired, the individual components of resuscitation to be offered, if any, will be dictated by the medical team’s clinical assessment.

Gene regulation is inherently stochastic. In many applications concerning Systems and Synthetic Biology such as the reverse engineering and the de novo design of genetic circuits, stochastic effects (yet potentially crucial) are often neglected due to the high computational cost of stochastic simulations. With advances in these fields there is an increasing need of tools providing accurate approximations of the stochastic dynamics of gene regulatory networks (GRNs) with reduced computational effort. This work presents SELANSI (SEmi-LAgrangian SImulation of GRNs), a software toolbox for the simulation of stochastic multidimensional gene regulatory networks. SELANSI exploits intrinsic structural properties of gene regulatory networks to accurately approximate the corresponding chemical master equation (CME) with a partial integral differential equation (PIDE) that is solved by a semi-lagrangian method with high efficiency. Networks under consideration might involve multiple genes with self and cross regulations, in which genes can be regulated by different transcription factors. Moreover, the validity of the method is not restricted to a particular type of kinetics. The tool offers total flexibility regarding network topology, kinetics and parameterization, as well as simulation options. SELANSI runs under the MATLAB environment, and is available under GPLv3 license at https://sites.google.com/view/selansi. firstname.lastname@example.org.

Understanding of the climate sytems has been of tremendous importance to different branches such as agriculture, flood, drought and water resources management etc. In this regard, complex networks analysis and time series analysis attracted considerable attention, owing to their potential role in understanding the climate system through characteristic properties. One of the basic requirements in studying climate network dynamics is to identify connections in space or time or space-time, depending upon the purpose. Although a wide variety of approaches have been developed and applied to identify and analyse spatio-temporal relationships by climate networks, there is still further need for improvements in particular when considering precipitation time series or interactions on different scales. In this regard, recent developments in the area of network theory, especially complex networks, offer new avenues, both for their generality about systems and for their holistic perspective about spatio-temporal relationships. The present study has made an attempt to apply the ideas developed in the field of complex networks to examine connections in regional climate networks with particular focus on multiscale spatiotemporal connections. This paper proposes a novel multiscale understanding of regional climate networks using wavelets. The proposed approach is applied to daily precipitation records observed at 543 selected stations from south Germany for a period of 110 years (1901-2010). Further, multiscale community mining is performed on the same study region to shed more light on the underlying processes at different time scales. Various network measure and tools so far employed provide micro-level (individual station) and macro-level (community structure) information of the network. It is interesting to investigate how the result of this study can be useful for future climate predictions and for evaluating climate models on their implementation regarding heavy

Although artificial neural networks have shown great promise in applications including computer vision and speech recognition, there remains considerable practical and theoretical difficulty in optimizing their parameters. The seemingly unreasonable success of gradient descent methods in minimizing these non-convex functions remains poorly understood. In this work we offer some theoretical guarantees for networks with piecewise affine activation functions, which have in recent years become the norm. We prove three main results. First, that the network is piecewise convex as a function of the input data. Second, that the network, considered as a function of the parameters in a single layer, all others held constant, is again piecewise convex. Third, that the network as a function of all its parameters is piecewise multi-convex, a generalization of biconvexity. From here we characterize the local minima and stationary points of the training objective, showing that they minimize the objective on certain subsets of the parameter space. We then analyze the performance of two optimization algorithms on multi-convex problems: gradient descent, and a method which repeatedly solves a number of convex sub-problems. We prove necessary convergence conditions for the first algorithm and both necessary and sufficient conditions for the second, after introducing regularization to the objective. Finally, we remark on the remaining difficulty of the global optimization problem. Under the squared error objective, we show that by varying the training data, a single rectifier neuron admits local minima arbitrarily far apart, both in objective value and parameter space.

Current Online social networks (OSN) are web services run on logically centralized infrastructure. Large OSN sites use content distribution networks and thus distribute some of the load by caching for performance reasons, nevertheless there is a central repository for user and application data. This centralized nature of OSNs has several drawbacks including scalability, privacy, dependence on a provider, need for being online for every transaction, and a lack of locality. There have thus been several efforts toward decentralizing OSNs while retaining the functionalities offered by centralized OSNs. A decentralized online social network (DOSN) is a distributed system for social networking with no or limited dependency on any dedicated central infrastructure. In this chapter we explore the various motivations of a decentralized approach to online social networking, discuss several concrete proposals and types of DOSN as well as challenges and opportunities associated with decentralization.

Most food-environment research has focused narrowly on select stores and restaurants. There has been comparatively less attention to non-storefront food sources like farmers' markets (FMs), particularly in urban communities. The objective of the present study was to assess FMs' potential contribution to an urban food environment in terms of specific foods offered, and compare FM accessibility as well as produce variety, quality, and price to that of nearby stores. Investigators conducted a detailed cross-sectional assessment of all FMs in Bronx County, NY, and of the nearest store(s) selling produce within a half-mile walking distance (up to two stores per FM). The study included 26 FMs and 44 stores. Investigators assessed accessibility (locations of FMs and stores relative to each other, and hours of operation for each), variety (the number and type of all food items offered at FMs and all fresh produce items offered at stores), quality (where produce items were grown and if they were organic), and price (including any sales prices or promotional discounts). Analyses included frequencies, proportions, and variable distributions, as well as mixed-effect regressions, paired t-tests, and signed rank tests to compare FMs to stores. Geographic information systems (GIS) allowed for mapping of FM and store locations and determining street-network distances between them. The mean distance between FMs and the nearest store selling fresh produce was 0.15 miles (range 0.02-0.36 miles). FMs were open substantially fewer months, days, and hours than stores. FMs offered 26.4 fewer fresh produce items on average than stores (p values access to stores with cheaper prices and overwhelmingly more hours of operation. Copyright © 2015 Elsevier Ltd.

Physiology changes at the structural, functional, and molecular levels as people age, and every major organ system experiences physiologic change with time. The changes to the nervous system result mostly in cognitive impairments, the cardiovascular system develops higher blood pressures with lower cardiac output, the respiratory system undergoes a reduction of arterial oxyhemoglobin levels, the gastrointestinal system experiences delayed gastric emptying and reduction of hepatic metabolism, and the renal system experiences a diminished glomerular filtration rate. Combined, these changes create a complex physiologic condition. This unique physiology must be taken into consideration for geriatric patients undergoing general anesthesia.

Work at the Los Alamos Scientific Laboratory on the fundamental solution chemistry of the actinides has thus far been confined to preliminary considerations of the problems involved in developing an understanding of the precipitation and dissolution behavior of actinide compounds under environmental conditions. Attempts have been made to calculate solubility as a function of Eh and pH using the appropriate thermodynamic data; results have been presented in terms of contour maps showing lines of constant solubility as a function of Eh and pH. Possible methods of control of the redox potential of rock-groundwater systems by the use of Eh buffers (redox couples) is presented.

Family, network or couples-based therapies have been helping to support people with substance problems for decades. Their value in supporting a person to change their alcohol or drug use is clear. However, as links between substance use and domestic abuse are increasingly recognised, these approaches need to reflect on the potential safety risks they present to people taking part. The prevalence of domestic abuse among people receiving drug and alcohol services is considerably higher than general population estimates, yet this does not appear to have been adequately addressed in network therapies. This article suggests that this needs to change and that safety of service users needs to be at least as important as the intervention itself. It offers for debate a number of potential safety issues raised by network therapies where there is evidence of domestic abuse; it provides examples of three approaches used to marshal social and network support in substance interventions; and offers a number of suggestions for how network therapies can ensure their use remains safe and supportive where there is domestic abuse.

It has been considered a study of nutritional menus offered at noon School in Granada. Balanced diet in children and youth will enable the prevention of diseases in adulthood. Comparing the menus prepared on school and the services offered by catering. The menus are aimed at 5,399 children from Granada, analyzed 354 school menus from 29 centres, public and private schools. Eleven colleges have their own kitchen, while 18 had hired a catering service. The amounts provided in each menu were estimated using standardized photographs of different sizes ration identified by those responsible for the dining room or by weighing Served directly from the ration. Nutritional assessment was determined by software, and the statistical treatment with the program SPSS v. 15.0. There were statistically significant differences in the intakes of energy and nutrients from the menus developed in the centres and catering services. In the catering firms, the available energy and nutrition is similar, and in the menus prepared at the centres, there are significant differences in relation to some nutrients, depending on whether public school or private. The energy, protein and lipid is high and low input from carbohydrates. It is the frequency of excessive consumption of meat and derivatives. To balance the diet of school, it is necessary to complement the menu of midday meals with the rest of the day.

Full Text Available The tradeoff theory suggests that companies must issue shares to investments, when its leverage index is greater than your target rate, while the pecking order theory predicts that when capital offerings occur, the capital will be used to finance investments as the last source of funding, after their debt capacity have been exhausted. In contrast, the market timing theory predicts arguments that companies will adopt opportunistic behavior by issuing shares to take advantage of the high prices of the shares. Although the market timing theory has a significant influence on the decision to make a SEO, Brazilian literature contains little evidence about their economic importance and their effects. Thus, the present research aims to fill this gap in the Brazilian scenario. Specifically, we sought to assess the explanatory power of the relationship of market timing and the lifecycle theory in the issuance of SEO, which predicts that young companies with high market-to-book (MB and low operating cash flow sell shares to finance the investment, while mature companies, with low MB, pay dividends and fund investment internally. The sample was composed by non-financial companies with shares traded on BM&FBovespa. As main results, we can conclude that there is relationship between SEO and MB and size. On the other hand, were not observed evidence confirming the relationship between lifecycle stage and stock return, both in the previous year, and the year following the completion of the offer.

Creative, dynamic strategies are the ones that identify new and better ways of uniquely offering the target customers what they want or need. A business can achieve competitive advantage if it chooses a marketing strategy that sets the business apart from anyone else. Healthcare services companies have to understand that the customer should be placed in the centre of all specific marketing operations. The brand message should reflect the focus on the patient. Healthcare products and services offered must represent exactly the solutions that customers expect. The touchpoints with the patients must be well mastered in order to convince them to accept the proposed solutions. Healthcare service providers must be capable to look beyond customer's behaviour or product and healthcare service aquisition. This will demand proactive and far-reaching changes, including focusing specifically on customer preference, quality, and technological interfaces; rewiring strategy to find new value from existing and unfamiliar sources: disintegrating and radically reassembling operational processes: and restructuring the organization to accommodate new types of work and skill.

Revision rhinoplasty is a unique challenge. In addition to the technical considerations that are inherently more difficult than those of primary cases, the surgeon must also be mindful of the psychological considerations that revision rhinoplasty presents. These patients are by definition unhappy with their prior rhinoplasty experience, and this perception of a suboptimal result is both legitimate and real, even if the surgeon is not in agreement. Tantamount to any intraoperative technique, the preoperative ability of the surgeon to sift through the myriad psychological and psychosocial issues is critical to achieving satisfactory outcomes for both patient and surgeon. Reasons for dissatisfaction with a primary surgery, reasons for seeking revision surgery, and the psychological profiles of revision rhinoplasty patients can differ from those related to other facial cosmetic procedures. This article attempts to provide the reader with a better understanding of the complex interplay of these issues and with this understanding help the reader to distinguish one who is a favorable surgical candidate from one who is best left unrevised.

To review the scientific and regulatory aspects of biosimilar development and practical considerations for the use of biosimilars that are relevant to pharmacists. Literature searches of PubMed and congress abstracts for publications pertaining to biosimilars were conducted from January 2016 to January 2017. Individual drug company web pages and governmental, regulatory, and other agency websites were also reviewed. Published articles, regulatory guidelines, and other sources covering biologic/biosimilar development and approval, reporting results of biosimilar studies or survey research, and/or identifying biosimilars in development or approved for use in Europe or the United States were reviewed and included. Biologic therapies have revolutionized the treatment of serious diseases, including hematological or autoimmune disorders and cancers. A biosimilar is highly similar to a licensed biologic (ie, reference or originator) and has no clinically meaningful differences in safety, purity, and potency. Unlike small-molecule drugs, biologics are large, complex proteins that cannot be exactly replicated, so the concept of a generic equivalent cannot be applied to biologics. Regulatory agencies have provided a framework for biosimilar approval, but there are many practical considerations for pharmacists, including interchangeability, substitution, naming, indication extrapolation, product labeling, therapeutic drug monitoring, manufacturer attributes, logistics of product use, and reimbursement. Pharmacists will play a key role in managing the introduction of biosimilars into health care systems. Understanding the principles of biosimilar development and evolving regulatory guidelines relevant to their use will allow pharmacists to make informed decisions regarding formulary inclusion and educate patients and other health care providers about biosimilars.

Action to mitigate greenhouse gas emissions is essential for addressing rapid environmental change in the Earth's polar regions. However, the potential for threshold crossing events in polar climate elements with untenable consequences for society and ecosystems may motivate consideration of additional "climate interventions". A recent National Research Council study identified risks and research needs associated with global scale intervention options such as atmospheric carbon removal and albedo modification. In addition to the issues raised by the NRC panel, any serious study of climate interventions would likely transcend the traditional scope of earth system science. Current observational systems are not designed to detect, attribute or monitor climate intervention attempts and would warrant significant augmentation. Potential field experiments to improve scientific understanding of albedo modification options would likely span a huge range of physical scales, material and energy (some in-family with established atmospheric research but others that would be wholly unprecedented). Targeted interventions focused on polar climate elements have received even less study than global-scale intervention and their consideration could present unique challenges. Finally, research priorities have not yet been informed by any strategy or scenarios about where and when climate interventions might fit in society's portfolio of climate responses.

Since the beginning of the raw material boom four years ago the positive trend in the mining machinery branch in Germany has accelerated. The globalisation of the branch was assisted by the good national and international network between manufacturers of mining equipment, associations, consultants, financial institutions and politicians. The branch is currently well established internationally with an export share of 86%. This puts it into a position to continue to utilise the opportunities offered by the raw material boom. (orig.)
Full Text Available Hospital networks, formed by patients visiting multiple hospitals, affect the spread of hospital-associated infections, resulting in differences in risks for hospitals depending on their network position. These networks are increasingly used to inform strategies to prevent and control the spread of hospital-associated pathogens. However, many studies only consider patients that are received directly from the initial hospital, without considering the effect of indirect trajectories through the network. We determine the optimal way to measure the distance between hospitals within the network, by reconstructing the English hospital network based on shared patients in 2014-2015, and simulating the spread of a hospital-associated pathogen between hospitals, taking into consideration that each intermediate hospital conveys a delay in the further spread of the pathogen. While the risk of transferring a hospital-associated pathogen between directly neighbouring hospitals is a direct reflection of the number of shared patients, the distance between two hospitals far-away in the network is determined largely by the number of intermediate hospitals in the network. Because the network is dense, most long distance transmission chains in fact involve only few intermediate steps, spreading along the many weak links. The dense connectivity of hospital networks, together with a strong regional structure, causes hospital-associated pathogens to spread from the initial outbreak in a two-step process: first, the directly surrounding hospitals are affected through the strong connections, second all other hospitals receive introductions through the multitude of weaker links. Although the strong connections matter for local spread, weak links in the network can offer ideal routes for hospital-associated pathogens to travel further faster. This hold important implications for infection prevention and control efforts: if a local outbreak is not controlled in time

The ultimate proof of our understanding of natural or technological systems is reflected in our ability to control them. While control theory offers mathematical tools to steer engineered systems towards a desired state, we lack a general framework to control complex self-organized systems, like the regulatory network of a cell or the Internet. Here we develop analytical tools to study the controllability of an arbitrary complex directed network, identifying the set of driver nodes whose time-dependent control can guide the system's dynamics. We apply these tools to real and model networks, finding that sparse inhomogeneous networks, which emerge in many real complex systems, are the most difficult to control. In contrast, dense and homogeneous networks can be controlled via a few driver nodes. Counterintuitively, we find that in both model and real systems the driver nodes tend to avoid the hubs. We show that the robustness of control to link failure is determined by a core percolation problem, helping us understand why many complex systems are relatively insensitive to link deletion. The developed approach offers a framework to address the controllability of an arbitrary network, representing a key step towards the eventual control of complex systems.

A number of past and most recent research findings that describe some of the physiological responses to exercise in man and their relationship with exposure to various gravitational environments are discussed. Most of the data pertain to adaptations of the cardiovascular and body fluid systems. It should be kept in mind that the data from studies on microgravity simulation in man include exposures of relatively short duration (5 hours to 14 days). However, it is argued that the results may provide important guidelines for the consideration of many variables which are pertinent to the development of exercise prescription for long-duration space flight. The following considerations for exercise prescriptions during long-duration space flight are noted: (1) Relatively high aerobic fitness and strength, especially of the upper body musculature, should be a criterion for selection of astronauts who will be involved in EVA, since endurance and strength appear to be predominant characteristics for work performance. (2) Some degree of upper body strength will probably be required for effective performance of EVA. However, the endurance and strength required by the upper body for EVA can probably be obtained through preflight exercise prescription which involves swimming. (3) Although some degree of arm exercise may be required to maintain preflight endurance and strength, researchers propose that regular EVA will probably be sufficient to maintain the endurance and strength required to effectively perform work tasks during space flight. (4) A minimum of one maximal aerobic exercise every 7 to 10 days during space flight may be all that is necessary for maintenance of normal cardiovascular responsiveness and replacement of body fluids for reentry following prolonged space flight. (5) The possible reduction in the amount of exercise required for maintenance of cardiovascular system and body fluids in combination with the use of electromyostimulation (EMS) or methods other
This paper tackles the problem of how two selfish users jointly determine the operating point in the achievable rate region of a two-user Gaussian interference channel through bargaining. In previous work, incentive conditions for two users to cooperate using a simple version of Han-Kobayashi scheme was studied and the Nash bargaining solution (NBS) was used to obtain a fair operating point. Here a noncooperative bargaining game of alternating offers is adopted to model the bargaining process and rates resulting from the equilibrium outcome are analyzed. In particular, it is shown that the operating point resulting from the formulated bargaining game depends on the cost of delay in bargaining and how bargaining proceeds. If the associated bargaining problem is regular, a unique perfect equilibrium exists and lies on the individual rational efficient frontier of the achievable rate region. Besides, the equilibrium outcome approaches the NBS if the bargaining costs of both users are negligible.
Full Text Available Challenging behaviors can significantly alter the learning environment of any classroom. Traditionally, schools have implemented practices that remove the offending student from the classroom, deliver punitive disciplinary actions, or refer the student to special education evaluation. Unfortunately, such practices have demonstrated little longitudinal effectiveness, with detrimental outcomes for the referred student, particularly students from Latino backgrounds. With enrollment projections indicating Latinos will become the majority in U.S. schools, educators are presented with the opportunity to shift away from past practices and implement evidence-based practices that concurrently assist students while addressing challenging behaviors. In this paper, the authors discuss past disciplinary practices, the adverse effects on Latino students, and offer recommendations on implementing functional behavioral assessment as a means to better meet the needs of Latino students demonstrating challenging behaviors.

Do all physician executives have much "catching up" to do in relation to their non-MD colleagues? A comparison of the role of the physician executive versus the non-MD executive/administrator provides a big picture view and signals new opportunities for physicians in the evolving health care system. Physician executives have only recently become invested in the health care executive suite and are less wedded to old methods and "classic" ideas. They are more likely to be able to adapt to new circumstances, jettisoning traditional approaches that have outlived their usefulness. But each group-physician executives and their MHA- or MBA-credentialed, non-MD colleagues- has much to offer to or learn from the other. By retaining those skills that are applicable, while also adapting the useful characteristics of the "traditional" health care administrator, a physician executive can increase the likelihood of success today.

Declarative Networking is a programming methodology that enables developers to concisely specify network protocols and services, which are directly compiled to a dataflow framework that executes the specifications. Declarative networking proposes the use of a declarative query language for specifying and implementing network protocols, and employs a dataflow framework at runtime for communication and maintenance of network state. The primary goal of declarative networking is to greatly simplify the process of specifying, implementing, deploying and evolving a network design. In addition, decla

Accurate determination of walking capacity is important for the clinical diagnosis and management plan for patients with peripheral arterial disease. The current "gold standard" of measurement is walking distance on a treadmill. However, treadmill testing is not always reflective of the patient's natural walking conditions, and it may not be fully accessible in every vascular clinic. The objective of this study was to determine whether Google Maps, the readily available GPS-based mapping tool, offers an accurate and accessible method of evaluating walking distances in vascular claudication patients. Patients presenting to the outpatient vascular surgery clinic between November 2013 and April 2014 at the Ottawa Hospital with vasculogenic calf, buttock, and thigh claudication symptoms were identified and prospectively enrolled in our study. Onset of claudication symptoms and maximal walking distance (MWD) were evaluated using four tools: history; Walking Impairment Questionnaire (WIQ), a validated claudication survey; Google Maps distance calculator (patients were asked to report their daily walking routes on the Google Maps-based tool runningmap.com, and walking distances were calculated accordingly); and treadmill testing for onset of symptoms and MWD, recorded in a double-blinded fashion. Fifteen patients were recruited for the study. Determination of walking distances using Google Maps proved to be more accurate than by both clinical history and WIQ, correlating highly with the gold standard of treadmill testing for both claudication onset (r = .805; P Google Maps tool was also efficient, with reporting times averaging below 4 minutes. For vascular claudicants with no other walking limitations, Google Maps is a promising new tool that combines the objective strengths of the treadmill test and incorporates real-world walking environments. It offers an accurate, efficient, inexpensive, and readily accessible way to assess walking distances in patients with

Slurry treatment is an innovative approach for bioremediation of contaminated soils under controlled conditions of pH, temperature, and nutrients. This treatment of excavated soils permits better control of environmental conditions than in landfarming, composting, and biocell units, and therefore may achieve accelerated rates of decontamination. Bioslurry reactors have been used to remediate a variety of contaminants, such as soils and sludges from refinery wastes, wood-preserving wastes, wastes containing polychlorinated biphenyls and halogenated solvents. Key considerations in design of such reactors involve meeting the oxygen requirements for biodegradation, preventing the settling of soil particles, efficient mixing of additives, and control of foaming. The aspects of reactor design, specifically agitation system have been discussed in this paper.
Cultural systems vary widely across the world. Partly this is due to different cultures' occupying different ecological and environmental niches. But partly it is due to similar circumstances giving rise to multiple stable equilibriums, each with a distinct cultural form. Using insights and examples from various fields, this article illustrates the way that multiple equilibriums can emerge and the forces that push a culture toward one equilibrium point or another. Considerations of game theory principles, mutual interdependence, historical circumstance, dependence on initial conditions, and crucial choice points are highlighted in discussing the ways humans create and re-create their culture. Cultural traits develop within physical, social, intracultural, and intercultural niches, and implications of this for how culture might be studied and the benefits of combining an "equilibrium" perspective and a "meaning" perspective are discussed.

Biosimilars are developed to be highly similar to and treat the same conditions as licensed biologics. As they are approved and their use becomes more widespread, oncology nurses should be aware of their development and unique considerations. This article reviews properties of biosimilars; their regulation and approval process; the ways in which their quality, safety, and efficacy are evaluated; their postmarketing safety monitoring; and their significance to oncology nurses and oncology nursing. . A search of PubMed and regulatory agency websites was conducted for references related to the development and use of biosimilars in oncology. . Because biologics are large, structurally complex molecules, biosimilars cannot be considered generic equivalents to licensed biologic products. Consequently, regulatory approval for biosimilars is different from approval for small-molecule generics. Oncology nurses are in a unique position to educate themselves, other clinicians, and patients and their families about biosimilars to ensure accurate understanding, as well as optimal and safe use, of biosimilars.

Full Text Available The term of education is an integral part of any programmatic political document on sustainable development. This fact underlines the significance that is assigned to education in the context of sustainable development. It leads to the question of what competencies teachers need in order to develop and implement educational offers in the field of Education for Sustainable Development (ESD so that they can aspire to and attain specific educational goals with their students. This touches on the question of the building of corresponding competencies in teacher education and further education. So far, few attempts have been made to describe teachers’ competencies regarding ESD and to develop corresponding competence models. The following article presents two models—Curriculum, Sustainable Development, Competences, Teacher Training (CSCT Model and Learning for the future: The Competences in Education for Sustainable Development (ECE Model—and discusses their benefit for teacher education and further education. These models differ in how broadly they define ESD and in what audiences they target at. This comparison shows and explains why competence models should focus on profession-specific core competencies if they are to be used as a basis for the conception of educational offers in the field of ESD in education and further education of teachers. The drawn conclusion consists in initial considerations for the conception of another competence model.

Sepsis is a common condition managed in the emergency department, and the majority of patients respond to resuscitation measures, including antibiotics and i.v. fluids. However, a proportion of patients will fail to respond to standard treatment. This review elucidates practical considerations for management of sepsis in patients who fail to respond to standard treatment. Early goal-directed therapy revolutionized sepsis management. However, there is a paucity of literature that provides a well-defined treatment algorithm for patients who fail to improve with therapy. Refractory shock can be defined as continued patient hemodynamic instability (mean arterial pressure, ≤ 65 mm Hg, lactate ≥ 4 mmol/L, altered mental status) after adequate fluid loading (at least 30 mL/kg i.v.), the use of two vasopressors (with one as norepinephrine), and provision of antibiotics. When a lack of improvement is evident in the early stages of resuscitation, systematically considering source control, appropriate volume resuscitation, adequate antimicrobial coverage, vasopressor selection, presence of metabolic pathology, and complications of resuscitation, such as abdominal compartment syndrome and respiratory failure, allow emergency physicians to address the entire clinical scenario. The care of sepsis has experienced many changes in recent years. Care of the patient with sepsis who is not responding appropriately to initial resuscitation is troublesome for emergency physicians. This review provides practical considerations for resuscitation of the patient with septic shock. When a septic patient is refractory to standard therapy, systematically evaluating the patient and clinical course may lead to improved outcomes. Published by Elsevier Inc.
Full Text Available the Second World War offered the opportunity, to the international community, to realize the total lack of international law prohibiting the worst inhumane acts. Particular gravity, the large number of casualties as a result of persecution or extermination of whole groups of people highlights crimes against humanity among offenses punishable by the criminal law, thus requiring additional scientific research and a more elaborate analysis. Effective punishment of crimes against humanity is an important element in the prevention of such crimes, the protection of human rights and fundamental freedoms, such as to encourage promote international peace and security. Crimes against humanity were first regulated by the rules of international criminal law after the Second World War as a response to the atrocities committed by the Nazi and Japanese fighting forces in the occupied territories, against the local population and in the death camps, of broad categories of people based on national, ethnic or racial.

This article gives an overview of the ethical issues in nutrigenomics research and personalized nutrition. The principles of research ethics, i.e., autonomy, beneficence, nonmalfeasance, and justice, are challenged by rapidly growing cross-border research activities utilizing existing and upcoming biobanks for studies of the interaction of genes with diet on risk of common diseases. We highlight the ethical issues, some unresolved, in international collaborative projects of which researchers should be aware. Personalized nutrition (tailoring diet on the basis of genotype) is one possible application of nutrigenomics research. However, until the scientific evidence concerning diet-gene interactions is much more robust, the provision of personalized dietary advice on the basis of specific genotype remains questionable. From the ethical and social perspective, nutrigenomics offers significant opportunities to improve public health by enhancing understanding of the mechanisms through which diet can be used to reduce the risk of common polygenic diseases.
The pharmacovigilance of drugs for orphan diseases presents problems related to the small patient population. Obtaining high-quality information on individual reports of suspected adverse reactions is of particular importance for the pharmacovigilance of orphan drugs. The possibility of mining "big data" to detect suspected adverse reactions is being explored in pharmacovigilance generally but may have limited application to orphan drugs. Sources of big data such as social media may be infrequently used as communication channels by patients with rare disease or their caregivers or by health care providers; any adverse reactions identified are likely to reflect what is already known about the safety of the drug from the network of support that grows up around these patients. Opportunities related to potential future big data sources are discussed. Copyright © 2016 Elsevier HS Journals, Inc. All rights reserved.

Monitoring the snow pack is crucial for many stakeholders, whether for hydro-power optimization, water management or flood control. Traditional forecasting relies on regression methods, which often results in snow melt runoff predictions of low accuracy in non-average years. Existing ground-based real-time measurement systems do not cover enough physiographic variability and are mostly installed at low elevations. We present the hardware and software design of a state-of-the-art distributed Wireless Sensor Network (WSN)-based autonomous measurement system with real-time remote data transmission that gathers data of snow depth, air temperature, air relative humidity, soil moisture, soil temperature, and solar radiation in physiographically representative locations. Elevation, aspect, slope and vegetation are used to select network locations, and distribute sensors throughout a given network location, since they govern snow pack variability at various scales. Three WSNs were installed in the Sierra Nevada of Northern California throughout the North Fork of the Feather River, upstream of the Oroville dam and multiple powerhouses along the river. The WSNs gathered hydrologic variables and network health statistics throughout the 2017 water year, one of northern Sierra's wettest years on record. These networks leverage an ultra-low-power wireless technology to interconnect their components and offer recovery features, resilience to data loss due to weather and wildlife disturbances and real-time topological visualizations of the network health. Data show considerable spatial variability of snow depth, even within a 1 km 2 network location. Combined with existing systems, these WSNs can better detect precipitation timing and phase in, monitor sub-daily dynamics of infiltration and surface runoff during precipitation or snow melt, and inform hydro power managers about actual ablation and end-of-season date across the landscape.

Fuel cells, which have recently received considerable attention for terrestrial applications ranging from automobiles to stationary power generation, may enable new aerospace missions as well as offer fuel savings, quiet operations, and reduced emissions for current and future aircraft. NASA has extensive experience with fuel cells, having used them on manned space flight systems over four decades. Consequently, the NASA Glenn Research Center has initiated an effort to investigate and develop fuel cell technologies for multiple aerospace applications. Two promising fuel cell types are the proton exchange membrane (PEM) and solid oxide fuel cell (SOFC). PEM technology, first used on the Gemini spacecraft in the sixties, remained unutilized thereafter until the automotive industry recently recognized the potential. PEM fuel cells are low-temperature devices offering quick startup time but requiring relatively pure hydrogen fuel. In contrast, SOFCs operate at high temperatures and tolerate higher levels of impurities. This flexibility allows SOFCs to use hydrocarbon fuels, which is an important factor considering our current liquid petroleum infrastructure. However, depending on the specific application, either PEM or SOFC can be attractive. As only NASA can, the Agency is pursuing fuel cell technology for civil uninhabited aerial vehicles (UAVs) because it offers enhanced scientific capabilities, including enabling highaltitude, long-endurance missions. The NASA Helios aircraft demonstrated altitudes approaching 100,000 ft using solar power in 2001, and future plans include the development of a regenerative PEM fuel cell to provide nighttime power. Unique to NASA's mission, the high-altitude aircraft application requires the PEM fuel cell to operate on pure oxygen, instead of the air typical of terrestrial applications.

In this letter, the problem of relay selection and optimal resource allocation for two-way relaying cognitive radio networks using half duplex amplify-and-forward and decode-and-forward protocols is investigated. The primary and secondary users are assumed to access the spectrum simultaneously, in a way that the interference introduced to the primary users should be below a certain tolerated limit. Dual decomposition and subgradient methods are used to find the optimal power allocation. A suboptimal approach based on a genetic algorithm is also presented. Simulation results show that the proposed suboptimal algorithm offers a performance close to the optimal performance with a considerable complexity saving. © 2013 IEEE.

Electronic cigarettes as possibly healthier alternative to conventional cigarettes are gaining popularity worldwide, although they are still hazardous to human health. Partly it is caused by unregulated advertising and online sales. Unfortunately it is more and more popular for youth to try electronic cigarettes. The aim of the study was to assess the marketing claims used by Polish websites offering electronic cigarettes. A search using Google search engine was performed in July 2015 for two keywords: e-papierosy [e-cigarettes] and elektroniczne papierosy [electronic cigarettes]. First 150 websites (15 pages) were listed. After initial review 86 pages met all inclusion criteria and were included in the study. Pages were searched for presence of 13 selected marketing claims as well as age-related warning and any social websites connections. Age-related warning was present on only 33.72% (n=29) websites. Two thirds has its own Facebook fan-page with average 1922.09 ± 3634.86 likes. Articles about health are available on 10.46% (n=9) websites, 53.49% (n=46) states that e-cigarettes are healthier than conventional ones, 39.53% (n=34) emphasized that during usage of e-cigarettes no tarry substances are produced. Two pages had special article in which conventional and electronic cigarettes were compared. Almost half (44.19%) remarked that e-cigarettes are cheaper in usage than conventional, one third pointed out the simplicity of usage. 32.56% advertised e-cigarettes as aid in quitting smoking. One fourth stated that e-cigarettes are harmless for surroundings. 33.72% marketed them as a way of bypassing public smoking act. 56.98% remarked the variety of liquid tastes offered. Electronic cigarettes and their rising popularity create another new possible threat for public health as the widely available information emphasize safety of e-cigarettes usage and as their availability and usage is not limited or restricted by law. electronic cigarettes, e-cigarettes, internet

Comparisons of survival after single lung transplant (SLT) and bilateral lung transplant (BLT) are useful in making policy decisions, but a more relevant comparison for an individual patient is between accepting a single lung when offered and remaining on the waiting list with the potential to subsequently receive a suitable pair of lungs. U.K. data from a cohort of 1211 adult, first lung transplant candidates diagnosed with pulmonary fibrosis (PF) or chronic obstructive pulmonary disease (COPD), listed July 1995 to July 2006 and followed up till December 2007, were analyzed. A sequentially stratified proportional hazards model was used to assess mortality after SLT relative to continued waiting for BLT. For patients with PF, SLT was associated with a significant reduction in hazard relative to waiting for BLT (hazard ratio 0.81, 95% confidence interval 0.68-0.97, P=0.021), particularly for older patients with body mass index less than 20 and forced expired volume in 1 sec is less than 1 L. In contrast, our results gave no support for accepting SLT rather than waiting for BLT for patients with COPD (hazard ratio 1.08, 95% confidence interval 0.92-1.29, P=0.35). The high pretransplant risk of death for patients with PF, particularly older patients with low body mass index and poor lung function, suggests that they would benefit from taking an SLT if offered. However, there is no benefit of accepting SLT rather than waiting for BLT for patients with COPD; this reflects the low relative hazard in the absence of transplant for these patients. © 2011 by Lippincott Williams & Wilkins

The purpose of this paper is to provide a snapshot of current developments and future direction of research on wearable and implantable body area network systems for continuous monitoring of patients. This paper explains the important role of body sensor networks in medicine to minimize the need for caregivers and help the chronically ill and elderly people live an independent life, besides providing people with quality care. The paper provides several examples of state of the art technology together with the design considerations like unobtrusiveness, scalability, energy efficiency, security and also provides a comprehensive analysis of the various benefits and drawbacks of these systems. Although offering significant benefits, the field of wearable and implantable body sensor networks still faces major challenges and open research problems which are investigated and covered, along with some proposed solutions, in this paper.

Le reti museali come “sistemi” capaci di generare valore: verso un approccio manageriale e di marketing / Museum networks as “systems” able to create value: towards a management and marketing approach
The aim of this paper is to offer a mainly theoretical consideration about organizational and management approaches for museum networks through the analysis of two case studies drawn from the context of Le Marche Italian region.The study shows how museum networks represent a potentially effective organizational form for enhancing cultural resources able to create value for consumers as well as local stakeholders. However, as in many cases of business aggregation – as the Viable Systems Approach suggests – networks qualify as systems that can survive and develop when managedby a governing body capable of guiding the network for the purposes of development and long-term success. This is imperative for museum networks in order to create value for both producers and consumers of cultural products.

Space activities after a phase of research and development, political competition and national prestige have entered an era of real commercialization. Remote sensing, earth observation, and communication are among the areas in which this growing industry is facing competition and declining government money. A project like International Space Station, which draws from public money, has not only opened a window of real multinational cooperation, but also changed space travel from a mere fantasy into a real world activity. Besides research activities for sending man to moon and Mars and other outer planets, space travel has attracted a considerable attention in recent years in the form of space tourism. Four countries from space fairing nations are actively involved in the development of space tourism. Even, nations which are either in early stages of space technology development or just beginning their space activities, have high ambitions in this area. This is worth noting considering their limited resources. At present, trips to space are available, but limited and expensive. To move beyond this point to generally available trips to orbit and week long stays in LEO, in orbital hotels, some of the required basic transportations, living requirements, and technological developments required for long stay in orbit are already underway. For tourism to develop to a real everyday business, not only the price has to come down to meaningful levels, but also safety considerations should be fully developed to attract travelers' trust. A serious hazard to space activities in general and space tourism in particular is space debris in earth orbit. Orbiting debris are man-made objects left over by space operations, hazardous to space missions. Since the higher density of debris population occurs in low earth orbit, which is also the same orbit of interest to space tourism, a careful attention should be paid to the effect of debris on tourism activities. In this study, after a

The recent seismic surveys in Falkland Islands waters by GECO-Prakla and Spectrum have encouraged substantial oil company interest in this new exploration area. An exclusive licensing round, based on competitive work programs, is expected to open in second half 1994 and close in early 1995. The fiscal terms and conditions relating to exploration and exploitation have yet to be finalized. However, it is expected that provisions will recognize the frontier nature of the area and will be designed to encourage operators fully to explore leased areas. The new seismic surveys are a considerable improvement on existing data acquired in the late 1970s and extend up to 380 km from the Falkland Island coast. The surveys cover all of the area in less than 200 m. The combined survey is probably the largest speculative shoot ever undertaken in a single season. This paper discusses the generalized geology, the Falkland Plateau basin, the Malvinas basin, the South Falkland basin, the Burdwood bank, and the northern basins.

Many physical, biological, and social phenomena can be described by cascades taking place on a network. Often, the activity can be empirically observed, but not the underlying network of interactions. In this paper we offer three topological methods to infer the structure of any directed network given a set of cascade arrival times. Our formulas hold for a very general class of models where the activation probability of a node is a generic function of its degree and the number of its active neighbors. We report high success rates for synthetic and real networks, for several different cascade models.

Full Text Available This paper aims to establish the link between tourists’ perceptions on cultural offers and their overall satisfaction, and explore the implication of this link for sustainable tourist destination management. Assessing online customers’ reviews, this study identifies a positive correlation between visitors’ perspectives and experiences at the on-site cultural centre and visitors’ destination satisfaction. It suggests that the on-site cultural centre plays a critical role in building up visitors’ perception on cultural attributes of the destination, and its impact on visitor satisfaction is a double-edged sword. Visitors’ positive perspectives on the cultural centre enhance visitors’ experiences and contribute to their destination satisfaction; however, not only does a negative perspective on their cultural and spiritual experience compromise visitors’ satisfaction, but also subsequent negative online reviews damage the destination image and discourage visitor return/visit. The findings help destination management organisations to better understand visitors’ preference for cultural centres and therefore to improve visitors’ cultural experience. This paper appeals for further study of on-site cultural centres’ role in forming destination cultural attributes, and of social media’s potential in enriching cultural experience.

As weight loss in primary care remains minimal, Health Professionals are advised to medically manage obesity-related risk factors including blood pressure and cholesterol. This experimental study evaluated the impact of medically managing risk factors on obese patients' motivation to change their behaviour. A vignette study with two arms: successful medical management (ie risk factors have improved) vs failed medical management (ie no change) set in three General Practices in the South of England. Overweight and obese patients (n=170) rated their behavioural intentions and beliefs after reading a vignette describing an overweight patient who had received either successful or failed medical management of their risk factors (blood pressure and cholesterol). Following successful medical management overweight and obese patients reported increased intentions to lose weight and a greater understanding of their condition. Medical management may change patient's understanding of their weight problem and motivate them to lose weight. Successful management relating to improvements in blood pressure and cholesterol may offer renewed hope and motivate obese patients to change their behaviour. This could be used as a teachable moment to encourage patients to see that obesity need not be an inevitable part of their lives. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The poverty trap concept strongly influences current research and policy on poverty alleviation. Financial or technological inputs intended to “push” the rural poor out of a poverty trap have had many successes but have also failed unexpectedly with serious ecological and social consequences that can reinforce poverty. Resilience thinking can help to (i) understand how these failures emerge from the complex relationships between humans and the ecosystems on which they depend and (ii) navigate diverse poverty alleviation strategies, such as transformative change, that may instead be required. First, we review commonly observed or assumed social-ecological relationships in rural development contexts, focusing on economic, biophysical, and cultural aspects of poverty. Second, we develop a classification of poverty alleviation strategies using insights from resilience research on social-ecological change. Last, we use these advances to develop stylized, multidimensional poverty trap models. The models show that (i) interventions that ignore nature and culture can reinforce poverty (particularly in agrobiodiverse landscapes), (ii) transformative change can instead open new pathways for poverty alleviation, and (iii) asset inputs may be effective in other contexts (for example, where resource degradation and poverty are tightly interlinked). Our model-based approach and insights offer a systematic way to review the consequences of the causal mechanisms that characterize poverty traps in different agricultural contexts and identify appropriate strategies for rural development challenges.

To evaluate the effectiveness of the Mentors Offering Maternal Support (MOMS) program to promote maternal fetal attachment, maternal adaptation to pregnancy, self-esteem, and perceived community support in women within a military environment. A randomized, controlled, repeated measured pilot study compared two groups of pregnant military wives, a control group receiving standard prenatal care and an intervention group receiving a structured eight-session MOMS program. The study was conducted at two Air Force installations in Florida having joint (Air Force, Army, and Navy) operations and high deployment requirements. Sixty-five military wives in their first trimester of pregnancy (control group, n = 36 and intervention group, n = 29) completed all aspects of the study. Women randomized to the MOMS program received eight structured classes starting in the first trimester of pregnancy and occurring every other week until the third trimester. Outcome measures were obtained in each trimester. The women in the control group received usual prenatal care. No statistically significant differences were found between the two groups for any of the outcome variables. The interaction of the amount of contact the women had with their deployed husbands and group assignment was statistically different for two variables, the Relationship with Husband Scale and the Rosenberg Self-Esteem Inventory. © 2012 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

For more than four decades, planetary protection policy based on the Outer Space Treaty of 1967 has guided space missions in avoiding harmful cross-contamination during exploration. Throughout this time, the main emphasis of the policy has been based on protecting science and avoiding biological contamination. In light of new knowledge about planetary bodies and the diversity and capabilities of terrestrial microorganisms in extreme environments, as well as increased interest in human exploration activities beyond Earth orbit, it is appropriate to con-sider the ethical and policy implications of this approach. In June 2010, a workshop was held at Princeton, New Jersey, to focus on those implications, and to formulate recommendations for the space-faring nations of the world relating to concrete measures that might be undertaken to conduct space science studies and exploration within a sustainable framework that considers additional ethical perspectives as well as science protection. The workshop considered both current planetary protection policy (COSPAR, etc.) and the implications of protecting plan-ets beyond purely scientific considerations, especially in light of possible human missions of exploration. This talk provides a summary of the workshop discussions and results.

Full Text Available The World Health Organization (WHO is currently revisiting the ICD. In the 10th version of the ICD, approved in 1990, hypochondriacal symptoms are described in the context of both the primary condition hypochondriacal disorder and as secondary symptoms within a range of other mental disorders. Expansion of the research base since 1990 makes a critical evaluation and revision of both the definition and classification of hypochondriacal disorder timely. This article addresses the considerations reviewed by members of the WHO ICD-11 Working Group on the Classification of Obsessive-Compulsive and Related Disorders in their proposal for the description and classification of hypochondriasis. The proposed revision emphasizes the phenomenological overlap with both anxiety disorders (e.g., fear, hypervigilance to bodily symptoms, and avoidance and obsessive-compulsive and related disorders (e.g., preoccupation and repetitive behaviors and the distinction from the somatoform disorders (presence of somatic symptom is not a critical characteristic. This revision aims to improve clinical utility by enabling better recognition and treatment of patients with hypochondriasis within the broad range of global health care settings.

To achieve a successful increase in the plug-in battery electric vehicle (BEV) market, it is anticipated that a significant improvement in battery performance is required to increase the range that BEVs can travel and the rate at which they can be recharged. While the range that BEVs can travel on a single recharge is improving, the recharge rate is still much slower than the refueling rate of conventional internal combustion engine vehicles. To achieve comparable recharge times, we explore the vehicle considerations of charge rates of at least 400 kW. Faster recharge is expected to significantly mitigate the perceived deficiencies for long-distance transportation, to provide alternative charging in densely populated areas where overnight charging at home may not be possible, and to reduce range anxiety for travel within a city when unplanned charging may be required. This substantial increase in charging rate is expected to create technical issues in the design of the battery system and the vehicle's electrical architecture that must be resolved. This work focuses on vehicle system design and total recharge time to meet the goals of implementing improved charge rates and the impacts of these expected increases on system voltage and vehicle components.
Full Text Available Most consumers spend an important part of their free time looking for online information about the brands before taking a decision to purchase. The Internet is the main factor which has led to a considerable increase of the time allotted by consumers for search and comparing information about brands, as a step preceding the decision to purchase and also one of the most important factors that influence the interaction between the brand and the consumer. Although the general trend is that the public to become more active and more involved in the choice of the brand, consumer's responses to its messages obviously depend on cultural, social or economic factors. The work has the purpose to clarify what brand community means and how it appeared - if it was really built from scratch or it has already existed in a latent way and it must only be recognized - the characteristics of successful communities, which of the objectives of the brands can be achieved by means of these groups, what is the role of social media in the development of these communities, what kind of types of mem¬bers are likely to be encountered inside of the online communities and what is their proportion for each and which are the research methodologies that can give support to companies in monitoring these groups.

Full Text Available In this article we identified a number of factors influencing the consumers’ perceived risk. In the first part we conducted a review of the main issues that define the perceived risk by the consumer at the time of purchase, some of the lines of action of the organizations to diminish this risk perception and a number of influencing factors presented in the literature, with significant impact on the intensity with which risk is perceived by consumers. The second part of the article is based on the statistical information regarding e-commerce market, market in which the perceived risk plays an important role in the purchasing decision. Thus, based on available official statistics provided by Eurostat we have revealed the existence of certain links between electronic commerce and orientation towards risk and income levels, age and consumer educational level. The review is not intended to be exhaustive, the study taking into consideration only those links that can be identified from using official statistical data.
Full Text Available Previous neuroimaging research has identified brain regions activated when people’s fairness consideration changes under conditions of social exclusion. The current study used EEG data to examine the temporal process of changes in fairness consideration under social exclusion. In this study, a Cyberball game was administered to manipulate participants’ social exclusion or inclusion. Then, in the following Ultimatum game, participants’ brain potentials were recorded while they received fair/unfair offers from someone who previously excluded them, someone who previously included them, or a stranger. Results showed that feedback related negativity (FRN after onset of distribution outcome was more pronounced for unfair offers compared to fair offers. Moreover, the FRN was more negative-going in response to unfair offers from people who previously excluded them than from the includer and the stranger. Fair offers ¬¬¬elicited a larger P300 than unfair offers. In addition, P300 was more positive-going for unfair offers from the stranger than from the excluder and the includer. This study reveals a temporal process in which the effects of social exclusion on fair consideration are reflected in FRN in the early stage of outcome evaluation. These data also suggest that the FRN is modulated by the subjective evaluation of outcome events in a social context.

Full Text Available In this paper possible applications of responsive pricing scheme and Stackelberg game for pricing telecommunication services with service provider as a leader and users acting as followers are analyzed. We have classified users according to an elasticity criterion into inelastic, partially elastic and elastic users. Their preferences are modelled through utility functions, which describe users’ sensitivity to changes in the quality of service and price. In the proposed algorithm a bandwidth management server is responsible for performing automatic optimal bandwidth allocation to each user’s session while maximizing its expected utility and the overall service provider’s revenue. The pricing algorithm is used for congestion control and more efficient network capacity utilization. We have analyzed different scenarios of the proposed usage-based pricing algorithm. Particularly, the influence of the number of service classes on price setting in terms of service provider’s revenue and total users’ utility maximization are discussed. The model is verified through numerous simulations performed by software that we have developed for that purpose.

This paper would compile an analysis over a possible implementation of a cloud system, treating especially the legal aspect of this theme. In the Italian market has a large number of issues arise form cloud computing. First of all, this paper investigates the legal issues associated to cloud computing, specific contractual scheme that is able to define rights a duties both of user (private and/or public body and cloud provider. On one side there is all the EU legislative production related to privacy over electronic communication and, furthermore, the Privacy Directive is under a revision process to be more adaptable to new challenges of decentralized data treatment, but concretely there are no any structured and well defined legal instruments. Objectives: we present a possible solution to address the uncertainty of this area, starting from the EU legislative production with the help of the specific Italian scenario that could offer an operative solution. Indeed the Italian legal system is particularly adaptable to changing technologies and it could use as better as possible to adapt the already existing legal tools to this new technological era.

In 2004, complementary and alternative medicine (CAM) was offered by physicians in one-third of Swiss hospitals. Since then, CAM health policy has changed considerably. This study aimed to describe the present supply and use of CAM in hospitals in the French-speaking part of Switzerland, and to explore qualitatively the characteristics of this offer. Between June 2011 and March 2012, a short questionnaire was sent to the medical directors of hospitals (n = 46), asking them whether CAM was offered, where and by whom. Then, a semi-directive interview was conducted with ten CAM therapists. Among 37 responses (return rate 80%), 19 medical directors indicated that their hospital offered at least one CAM and 18 reported that they did not. Acupuncture was the most frequently available CAM, followed by manual therapies, osteopathy and aromatherapy. The disciplines that offered CAM most frequently were rehabilitation, gynaecology and obstetrics, palliative care, psychiatry, and anaesthetics. In eight out of ten interviews, it appeared that the procedures for introducing a CAM in the hospital were not tightly supervised by the hospital and were mainly based on the goodwill of the therapists, rather than clinical/scientific evidence. The number of hospitals offering CAM in the French-speaking part of Switzerland seemed to have risen since 2004. The selection of a CAM to be offered in a hospital should be based on the same procedure of evaluation and validation as conventional therapy, and if the safety and efficiency of the CAM is evidence-based, it should receive the same resources as a conventional therapy.

Full Text Available Diferentes estudios realizados en mercados de capital desarrollados han revelado tasas de retorno positivas inusuales de por lo menos 15% durante la fecha de anuncio de la oferta pública de adquisición de acciones. Aunque casi no se han llevado a cabo estudios sobre los mercados bursátiles en Sudamérica, algunos estudios han reportado tasas de retorno positivas inusuales en un rango del 25% al 50%, las cuales están relacionadas con el anuncio de la primera oferta de adquisición. En el presente estudio, se argumenta que las tasas de retorno positivas inusuales estimadas en los mercados emergentes son altas porque los estudios se han basado en un mercado de capitales totalmente segmentado aplicando el modelo de mercado y utilizando un índice del mercado bursátil local. Al considerar la integración parcial entre los cinco mercados emergentes en Sudamérica, se demuestra que efectivamente existen tasas de retorno positivas inusuales antes, durante y después de la fecha de anuncio de la primera oferta de adquisición. Sin embargo, el retorno positivo inusual asociado a la fecha del anuncio se encuentra en el orden del 8%. Utilizando un modelo de mercado que considere la integración parcial y el riesgo a la baja, se obtiene una tasa de retorno inusual ligeramente mayor. Estos resultados señalan una menor tasa de retorno positiva inusual en la muestra de las empresas sudamericanas incluidas en el estudio.

Full Text Available Abstract Constant malaria monitoring and surveillance systems have been highlighted as critical for malaria elimination. The absence of robust monitoring and surveillance systems able to respond to outbreaks in a timely manner undeniably contributed to the failure of the last global attempt to eradicate malaria. Today, technological advances could allow for rapid detection of focal outbreaks and improved deployment of diagnostic and treatment supplies to areas needing support. However, optimizing diffusion activities (e.g., distributing vector controls and medicines, as well as deploying behaviour change campaigns requires networks of diverse scholars to monitor, learn, and evaluate data and multiple organizations to coordinate their intervention activities. Surveillance systems that can gather, store and process information, from communities to national levels, in a centralized, widely accessible system will allow tailoring of surveillance and intervention efforts. Different systems and, thus reactions, will be effective in different endemic, geographical or socio-cultural contexts. Investing in carefully designed monitoring technologies, built for a multiple-acter, dynamic system, will help to improve malaria elimination efforts by improving the coordination, timing, coverage, and deployment of malaria technologies.

The driving force behind the proposed Integrated Digital Services Network (ISDN) is identified as PTT's and industry. It is doubtful whether ISDN can satisfy business user requirements. For residential users, the prospects are even more uncertain, since the costs associated with the implementation of subscriber loops seem to be out of all proportion to the added value offered to end users in terms of new services. The evolution of IDN in Europe is such that it will leave substantial areas without digital connectivity for many years; morever, the transition from IDN to ISDN still requires the solution of many important problems at different levels of the network. Although ISDN can be expected to be offered gradually at national level in several countries in the coming years, access on a European scale will not be possible to any significant degree before the year 2000 and it will continue to remain unclear whether this offer will correspond to a real demand. It is shown that satellites could be of considerable help in solving Europe's communications problems. By providing instant coverage of the entire West European region, they can offer the benefits of ISDN wherever they are required.

While both economic and social considerations of fairness and equity play an important role in financial decision-making, it is not clear which of these two motives is more primal and immediate and which one is secondary and slow. Here we used variants of the ultimatum game to examine this question. Experiment 1 shows that acceptance rate of unfair offers increases when participants are asked to base their choice on their gut-feelings, as compared to when they thoroughly consider the available information. In line with these results, Experiments 2 and 3 provide process evidence that individuals prefer to first examine economic information about their own utility rather than social information about equity and fairness, even at the price of foregoing such social information. Our results suggest that people are more economically rational at the core, but social considerations (e.g., inequality aversion) require deliberation, which under certain conditions override their self-interested impulses.

Our results suggest that people are more economically rational at the core, but social considerations (e.g., inequality aversion require deliberation, which under certain conditions override their self-interested impulses.

New technologies analyzing fetal DNA in maternal blood have led to the wide commercial availability of non-invasive prenatal testing (NIPT). We present here for clinicians the ethical and policy issues related to an emerging practice option. Although NIPT presents opportunities for pregnant women, particularly women who are at increased risk of having a baby with an abnormality or who are otherwise likely to access invasive prenatal testing, NIPT brings significant ethics and policy challenges. The ethical issues include multiple aspects of informed decision-making, such as access to counselling about the possible results of the test in advance of making a decision about participation in NIPT. Policy considerations include issues related to offering and promoting a privately available medical strategy in publicly funded institutions. Ethics and policy considerations merge in NIPT with regard to sex selection and support for persons living with disabilities.

This paper will address theoretical and practical considerations for the emerging field of space economics and propose an editorial policy for a journal of space economics to provide a forum for the discussion of space economics issues. It is anticipated that initially the Journal of Space Economics will operate from two different nodes one offering a European perspective (University of Latvia) and the other a U.S. perspective (University of Wisconsin at Milwaukee). The first edition of the Journal of Space Economics will focus on issues likely to arise during the course of the International Lunar Decade 2020-2030.

Prediction and control of the dynamics of complex networks is a central problem in network science. Structural and dynamical similarities of different real networks suggest that some universal laws might accurately describe the dynamics of these networks, albeit the nature and common origin of such laws remain elusive. Here we show that the causal network representing the large-scale structure of spacetime in our accelerating universe is a power-law graph with strong clustering, similar to many complex networks such as the Internet, social, or biological networks. We prove that this structural similarity is a consequence of the asymptotic equivalence between the large-scale growth dynamics of complex networks and causal networks. This equivalence suggests that unexpectedly similar laws govern the dynamics of complex networks and spacetime in the universe, with implications to network science and cosmology.

Applied network theory has seen pronounced expansion in recent years, in fields such as epidemiology, computer science, and sociology. Concurrent development of analytical methods and frameworks has increased possibilities and tools available to researchers seeking to apply network theory to a variety of problems. While water and nutrient fluxes through stream systems clearly demonstrate a directional network structure, the hydrological applications of network theory remain underexplored. This presentation covers a review of network applications in hydrology, followed by an overview of promising network analytical tools that potentially offer new insights into conceptual modeling of hydrologic systems, identifying behavioral transition zones in stream networks and thresholds of dynamical system response. Network applications were tested along an urbanization gradient in Atlanta, Georgia, USA. Peachtree Creek and Proctor Creek. Peachtree Creek contains a nest of five longterm USGS streamflow and water quality gages, allowing network application of longterm flow statistics. The watershed spans a range of suburban and heavily urbanized conditions. Summary flow statistics and water quality metrics were analyzed using a suite of network analysis techniques, to test the conceptual modeling and predictive potential of the methodologies. Storm events and low flow dynamics during Summer 2016 were analyzed using multiple network approaches, with an emphasis on tomogravity methods. Results indicate that network theory approaches offer novel perspectives for understanding long term and eventbased hydrological data. Key future directions for network applications include 1) optimizing data collection, 2) identifying "hotspots" of contaminant and overland flow influx to stream systems, 3) defining process domains, and 4) analyzing dynamic connectivity of various system components, including groundwatersurface water interactions.

problem can be addressed, near the network edge, by applying dynamic, in-network adaptation (e.g., transcoding of video streams to meet available connection bandwidth, machine characteristics, and client preferences. In this paper, we extrapolate from earlier work of Shorfuzzaman et al. 2006 in which we implemented and assessed an MPEG-1 transcoding system on the Intel IXP1200 network processor to consider the feasibility of in-network transcoding for other video formats and network processor architectures. The use of “on-the-fly” video adaptation near the edge of the network offers the promise of simpler support for a wide range of end devices with different display, and so forth, characteristics that can be used in different types of environments.

The purpose of the report is to provide experienced-based insights into design processes that will benefit designers beginning their employment at Sandia National Laboratories or those assuming new design responsibilities. The main purpose of this document is to provide engineers with the practical aspects of system design. The material discussed here may not be new to some readers, but some of it was to me. Transforming an idea to a design to solve a problem is a skill, and skills are similar to history lessons. We gain these skills from experience, and many of us have not been fortunate enough to grow in an environment that provided the skills that we now need. I was fortunate to grow up on a farm where we had to learn how to maintain and operate several different kinds of engines and machines. If you are like me, my formal experience is partially based upon the two universities from which I graduated, where few practical applications of the technologies were taught. What was taught was mainly theoretical, and few instructors had practical experience to offer the students. I understand this, as students have their hands full just to learn the theoretical. The practical part was mainly left up to 'on the job experience'. However, I believe it is better to learn the practical applications early and apply them quickly 'on the job'. System design engineers need to know several technical things, both in and out of their field of expertise. An engineer is not expected to know everything, but he should know when to ask an expert for assistance. This 'expert' can be in any field, whether it is in analyses, drafting, machining, material properties, testing, etc. The best expert is a person who has practical experience in the area of needed information, and consulting with that individual can be the best and quickest way for one to learn. If the information provided here can improve your design skills and save one design from having a problem

'Linked Data' is a current buzz-phrase promoting access to various forms of data on the internet. It starts from the two principles that have underpinned the architecture and scalability of the World Wide Web: 1. Universal Resource Identifiers - using the http protocol which is supported by the DNS system. 2. Hypertext - in which URIs of related resources are embedded within a document. Browsing is the key mode of interaction, with traversal of links between resources under control of the client. Linked Data also adds, or re-emphasizes: • Content negotiation - whereby the client uses http headers to tell the service what representation of a resource is acceptable, • Semantic Web principles - formal semantics for links, following the RDF data model and encoding, and • The 'mashup' effect - in which original and unexpected value may emerge from reuse of data, even if published in raw or unpolished form. Linked Data promotes typed links to all kinds of data, so is where the semantic web meets the 'deep web', i.e. resources which may be accessed using web protocols, but are in representations not indexed by search engines. Earth sciences are data rich, but with a strong legacy of specialized formats managed and processed by disconnected applications. However, most contemporary research problems require a cross-disciplinary approach, in which the heterogeneity resulting from that legacy is a significant challenge. In this context, Linked Data clearly has much to offer the earth sciences. But, there are some important questions to answer. What is a resource? Most earth science data is organized in arrays and databases. A subset useful for a particular study is usually identified by a parameterized query. The Linked Data paradigm emerged from the world of documents, and will often only resolve data-sets. It is impractical to create even nested navigation resources containing links to all potentially useful objects or subsets. From the viewpoint of human user

In this paper, the Biham—Middleton—Levine (BML) model with consideration of cooperative willingness has been proposed to study the traffic flow in urban networks. An evolutionary game with a cooperative willingness profile is introduced to deal with conflicts between disturbing neighbors. Simulation results suggest that imitating cooperative willingness can ease the effect of premature seizure on traffic flow due to the introduction of evolutionary games. Phase diagrams with a strategy profile and cooperative willingness profile have been investigated in detail. Our findings also prove that by imitating the more successful, cooperative willingness instead of simply the more successful strategies, the evolution of cooperation is significantly promoted, hence improving the order of cooperation and relieving the pressure of traffic networks.

Social Network analysis focuses on patterns of relations between and among people, organizations, states, etc. It aims to describe networks of relations as fully as possible, identify prominent patterns in such networks, trace the flow of information through them, and discover what effects these relations and networks have on people and organizations. Social network analysis offers a very promising potential for analyzing human-human interactions in online communities (discussion boards, newsgroups, virtual organizations). This Tutorial provides an overview of this analytic technique and demonstrates how it can be used in Human Computer Interaction (HCI) research and practice, focusing especially on Computer Mediated Communication (CMC). This topic acquires particular importance these days, with the increasing popularity of social networking websites (e.g., youtube, myspace, MMORPGs etc.) and the research interest in studying them.

In this work, we analyze the performance of full-duplex relay selection (FDRS) in spectrum-sharing networks. Contrary to half-duplex relaying, full-duplex relaying (FDR) enables simultaneous listening/forwarding at the secondary relay(s), thereby allowing for a higher spectral efficiency. However, since the source and relay simultaneously transmit in FDR, their superimposed signal at the primary receiver should now satisfy the existing interference constraint, which can considerably limit the secondary network throughput. In this regard, relay selection can offer an adequate solution to boost the secondary throughput while satisfying the imposed interference limit. We first analyze the performance of opportunistic FDRS with residual self-interference (RSI) by deriving the exact cumulative distribution function of its end-to-end signal-to-interference-plus-noise ratio under Nakagami-m fading. We also evaluate the offered diversity gain of relay selection for different full-duplex cooperation schemes in the presence/absence of a direct source-destination link. When the adopted RSI link gain model is sublinear in the relay power, which agrees with recent research findings, we show that remarkable diversity gain can be recovered even in the presence of an interfering direct link. Second, we evaluate the end-to-end performance of FDRS with interference constraints due to the presence of a primary receiver. Finally, the presented exact theoretical findings are verified by numerical simulations.

There is increasing recognition that chronic illness management (CIM) is not just an individual but a collective process where social networks can potentially make a considerable contribution to improving health outcomes for people with chronic illness. However, the mechanisms (processes, activities) taking place within social networks are insufficiently understood. The aim of this review was to focus on identifying the mechanisms linking social networks with CIM. Here we consider network mechanisms as located within a broader social context that shapes practices, behaviours, and the multiplicity of functions and roles that network members fulfil. A systematic search of qualitative studies was undertaken on Medline, Embase, and Web for papers published between 1st January 2002 and 1st December 2013. Eligible for inclusion were studies dealing with diabetes, and with conditions or health behaviours relevant for diabetes management; and studies exploring the relationship between social networks, self-management, and deprivation. 25 papers met the inclusion criteria. A qualitative metasynthesis was undertaken and the review followed a line of argument synthesis. The main themes identified were: 1) sharing knowledge and experiences in a personal community; 2) accessing and mediation of resources; 3) self-management support requires awareness of and ability to deal with network relationships. These translated into line of argument synthesis in which three network mechanisms were identified. These were network navigation (identifying and connecting with relevant existing resources in a network), negotiation within networks (re-shaping relationships, roles, expectations, means of engagement and communication between network members), and collective efficacy (developing a shared perception and capacity to successfully perform behaviour through shared effort, beliefs, influence, perseverance, and objectives). These network mechanisms bring to the fore the close

To investigate factors that influence the antenatal screening practice of obstetricians and identify barriers to the implementation of universal antenatal HIV screening. A survey of all obstetricians registered with the Royal Australian and New Zealand College of Obstetricians and Gynaecologists. A questionnaire was mailed to all obstetricians in Australia, followed by two reminders. The overall response rate was 70% (817/1172) and of these 70% always offered an HIV test during pregnancy. Obstetricians offering the test were more likely to female or younger in age. Of respondents who always offered testing, 90% disagreed with only testing women with risk factors compared with only 34% of those who undertook a selective screening approach (adjusted odds ratio, 87.7; 95% confidence interval, 40-192; P = 0.001). Obstetricians who practiced selective screening were influenced by whether the woman had antenatal blood tests prior to her obstetric appointment or a previous negative HIV test. Obstetricians who practiced universal screening were more likely to be concerned about false-positive results. Many obstetricians, irrespective of their screening practice, agreed that many of the components of pretest counseling were inappropriate for the majority of women. A majority of obstetricians in Australia are offering all pregnant women an HIV test. Consideration should be given to tailoring pretest counseling requirements to the antenatal setting. Ongoing education regarding the limitations of selective screening and management of women with false-positive results is also highlighted by this study.

This study characterized mental health facilities that offer suicide prevention services or outcome follow-up after discharge. The study analyzed data from 8,459 U.S. mental health facilities that participated in the 2010 National Mental Health Services Survey. Logistic regression analyses were used to compare facilities that offered neither of the prevention services with those that offered both or either service. About one-fifth of mental health facilities reported offering neither suicide prevention services nor outcome follow-up. Approximately one-third offered both, 25% offered suicide prevention services only, and 21% offered only outcome follow-up after discharge. Facilities that offered neither service were less likely than facilities that offered either to offer comprehensive support services or special programs for veterans; to offer substance abuse services; and to be accredited, licensed, or certified. Further examination of facilitators and barriers in implementing suicide prevention services in mental health facilities is warranted.

Despite significant advances in characterizing the structural properties of complex networks, a mathematical framework that uncovers the universal properties of the interplay between the topology and the dynamics of complex systems continues to elude us. Here we develop a self-consistent theory of dynamical perturbations in complex systems, allowing us to systematically separate the contribution of the network topology and dynamics. The formalism covers a broad range of steady-state dynamical processes and offers testable predictions regarding the system's response to perturbations and the development of correlations. It predicts several distinct universality classes whose characteristics can be derived directly from the continuum equation governing the system's dynamics and which are validated on several canonical network-based dynamical systems, from biochemical dynamics to epidemic spreading. Finally, we collect experimental data pertaining to social and biological systems, demonstrating that we can accurately uncover their universality class even in the absence of an appropriate continuum theory that governs the system's dynamics.
This volume provides an introduction to and overview of the emerging field of interconnected networks which include multi layer or multiplex networks, as well as networks of networks. Such networks present structural and dynamical features quite different from those observed in isolated networks. The presence of links between different networks or layers of a network typically alters the way such interconnected networks behave – understanding the role of interconnecting links is therefore a crucial step towards a more accurate description of real-world systems. While examples of such dissimilar properties are becoming more abundant – for example regarding diffusion, robustness and competition – the root of such differences remains to be elucidated. Each chapter in this topical collection is self-contained and can be read on its own, thus making it also suitable as reference for experienced researchers wishing to focus on a particular topic.

Acupuncture as a therapeutic intervention has been widely used for treatment of many pathophysiological disorders. For achieving improved therapeutic effects, relatively thick acupuncture needles have been frequently used in clinical practice with, in turn, enhanced stimulation intensity. However due to the discomforting nature of the larger-diameter acupuncture needles there is considerable interest in developing advanced acupuncture therapeutical techniques that provide more comfort with improved efficacy. So motivated, we have developed a new class of acupuncture needles, porous acupuncture needles (PANs) with hierarchical micro/nano-scale conical pores upon the surface, fabricated via a simple and well known electrochemical process, with surface area approximately 20 times greater than conventional acupuncture needles. The performance of these high-surface-area PANs is evaluated by monitoring the electrophysiological and behavioral responses from the in vivo stimulation of Shenmen (HT7) points in Wistar rats, showing PANs to be more effective in controlling electrophysiological and behavioral responses than conventional acupuncture needles. Comparative analysis of cocaine induced locomotor activity using PANs and thick acupuncture needles shows enhanced performance of PANs with significantly less pain sensation. Our work offers a unique pathway for achieving a comfortable and improved acupuncture therapeutic effect.
Full Text Available Food and eating habits, together with adjacent agricultural activities have had and an important role in the development of modern society and the individual itself. Besides its nutritional role, food has become a main socio-cultural determinant, food consumption patterns being influenced, on one hand, by psycho-sensory and quality characteristics of the food product and, on the other hand, by the physiological state of the consumer and its main determinants: traditions, religion and culture. These elements, together with economic considerations have a significant share in shaping the modern eating habits. In this context, the present paper aims to identify and analyze the main capitalization methods of the food’s traditional potential in reshaping the modern food offer, starting with a literature review and continuing with an exploratory analyze of the traditional food sector in Romania. Considering the main directions outlined by literature, this article tries to identify a set of specific features of the traditional food sector in Romania both in terms of producer and consumer perspectives. In this regard, an interview and an exploratory based questionnaire study were conducted. Having as a starting point the wide variety of Romanian food resources, this study aims to highlight how culinary customs have been modeled throughout history in order to establish eating patterns as an assessment method based on the impact of technological progress on the future alimentation.
Full Text Available Large-scale daily commuting data were combined with detailed geographical information system (GIS data to analyze the loss of transport efficiency caused by drivers' uncoordinated routing in urban road networks. We used Price of Anarchy (POA to quantify the loss of transport efficiency and found that both volume and distribution of human mobility demand determine the POA. In order to reduce POA, a small number of highways require considerable decreases in traffic, and their neighboring arterial roads need to attract more traffic. The magnitude of the adjustment in traffic flow can be estimated using the fundamental measure traffic flow only, which is widely available and easy to collect. Surprisingly, the most congested roads or the roads with largest traffic flow were not those requiring the most reduction of traffic. This study can offer guidance for the optimal control of urban traffic and facilitate improvements in the efficiency of transport networks.

Full Text Available The language of networks now describes everything from the Internet to the economy to terrorist organizations. In distinction to a common view of networks as a universal, originary, or necessary form that promises to explain everything from neural structures to online traffic, this essay emphasizes the contingency of the network imaginary. Network form, in its role as our current cultural dominant, makes scarcely imaginable the possibility of an alternative or an outside uninflected by networks. If so many things and relationships are figured as networks, however, then what is not a network? If a network points towards particular logics and qualities of relation in our historical present, what others might we envision in the future? In many ways, these questions are unanswerable from within the contemporary moment. Instead of seeking an avant-garde approach (to move beyond networks or opting out of networks (in some cases, to recover elements of pre-networked existence, this essay proposes a third orientation: one of ambivalence that operates as a mode of extreme presence. I propose the concept of "network aesthetics," which can be tracked across artistic media and cultural forms, as a model, style, and pedagogy for approaching interconnection in the twenty-first century. The following essay is excerpted from Network Ambivalence (Forthcoming from University of Chicago Press.

Full Text Available Wireless sensor networks (WSNs have attracted considerable interest in the research community, because of their wide range of applications. However, due to the distributed nature of WSNs and their deployment in remote areas, these networks are vulnerable to numerous security threats that can adversely affect their proper functioning. Resource constraints in sensor nodes mean that security mechanisms with a large overhead of computation and communication are impractical to use in WSNs; security in sensor networks is, therefore, a challenge. Access control is a critical security service that offers the appropriate access privileges to legitimate users and prevents illegitimate users from unauthorized access. However, access control has not received much attention in the context of WSNs. This paper provides an overview of security threats and attacks, outlines the security requirements and presents a state-of-the-art survey on access control models, including a comparison and evaluation based on their characteristics in WSNs. Potential challenging issues for access control schemes in WSNs are also discussed.

In distributed computing environments, performance is often dominated by the time that it takes to move data over a network. In the case of data-centric applications, or Data Grids, this problem of data movement becomes one of the overriding concerns. This talk describes techniques for improving data movement in Grid environments that we refer to as 'logistics.' We demonstrate that by using storage and cooperative forwarding 'in' the network, we can improve end to end throughput in many cases. Our approach offers clear performance benefits for high-bandwidth, high-latency networks. This talk will introduce the Logistical Session Layer (LSL) and provide experimental results from that system.

However, it is not clear whether social distance and anonymity have an interactive impact on fairness evaluation during asset distribution and whether these processes can be documented in brain activity. Using a modified ultimatum game combined with measures of event related potential (ERP), we examined how social distance and anonymity modulate brain response to inequality. At the behavior level, we found that acceptance rate and reaction time can be substantially modified by social distance and anonymity. Feedback-related negativity, an ERP component associated with conflict between cognitive and emotion motives, was more negative in response to unfairness than fairness from strangers; however, it showed an opposite trend for unfair offers provided by friends, suggesting that the influence of social distance on fairness perception is relatively fast. The P300 in response to fair offers was more positive when the proposers made offers when uncertain about partner identity than when certain about partner identity. These results suggest that unfairness is evaluated in a fast conflict detection stage and a slower stage that integrates more complex social contextual factors such as anonymity.

A complete self-control mechanism is proposed in the dynamics of neural networks through the introduction of a time-dependent threshold, determined in function of both the noise and the pattern activity in the network. Especially for sparsely coded models this mechanism is shown to considerably improve the storage capacity, the basins of attraction, and the mutual information content.

Applications of satellite networks involving the use of small-aperture antennas and low-cost earth stations located at customer-premises sites are considered. Such VSAT (very small-aperture satellite) networks are beginning to be installed in domestic satellite neworks as well as internationally in INTELSAT, IBS, Internet, and VIST offerings. The way in which VSAT networks might be integrated into ISDN (an integrated services digital network) is considered. The integration of mobile satellite networks is also considered.

Despite substantial recent progress, our understanding of the principles and mechanisms underlying complex brain function and cognition remains incomplete. Network neuroscience proposes to tackle these enduring challenges. Approaching brain structure and function from an explicitly integrative perspective, network neuroscience pursues new ways to map, record, analyze and model the elements and interactions of neurobiological systems. Two parallel trends drive the approach: the availability of new empirical tools to create comprehensive maps and record dynamic patterns among molecules, neurons, brain areas and social systems; and the theoretical framework and computational tools of modern network science. The convergence of empirical and computational advances opens new frontiers of scientific inquiry, including network dynamics, manipulation and control of brain networks, and integration of network processes across spatiotemporal domains. We review emerging trends in network neuroscience and attempt to chart a path toward a better understanding of the brain as a multiscale networked system.

Previous studies have shown that ingroup/outgroup membership influences individual's fairness considerations. However, it is not clear yet how group membership influences brain activity when a recipient evaluates the fairness of asset distribution. In this study, subjects participated as recipients in an Ultimatum Game with alleged members of both an experimentally induced ingroup and outgroup. They either received extremely unequal, moderately unequal, or equal offers from proposers while electroencephalogram was recorded. Behavioral results showed that the acceptance rates for unequal offers were higher when interacting with ingroup partners than with outgroup partners. Analyses of event related potentials revealed that proposers' group membership modulated offer evaluation at earlier processing stages. Feedback-related negativity was more negative for extremely and moderately unequal offers compared to equal offers in the ingroup interaction whereas it did not show differential responses to different offers in the outgroup interaction. Analyses of event related oscillations revealed that the theta power (4-6 Hz) was larger for moderately unequal offers than equal offers in the ingroup interaction whereas it did not show differential responses to different offers in the outgroup interaction. Thus, early mechanisms of fairness evaluation are strongly modulated by the ingroup/outgroup membership of the interaction partner.

We survey the literature on social networks by putting together the economics, sociological and physics/applied mathematics approaches, showing their similarities and differences. We expose, in particular, the two main ways of modeling network formation. While the physics/applied mathematics approach is capable of reproducing most observed networks, it does not explain why they emerge. On the contrary, the economics approach is very precise in explaining why networks emerge but does a poor jo...

This chapter addresses various aspects of analyzing privacy breaches in social networks. We first review literature that defines three types of privacy breaches in social networks: interactive, active, and passive. We then survey the various network anonymization schemes that have been constructed to address these privacy breaches. After exploring these breaches and anonymization schemes, we evaluate a measure for determining the level of anonymity inherent in a network graph based on its topological structure. Finally, we close by emphasizing the difficulty of anonymizing social network data while maintaining usability for research purposes and offering areas for future work.

Location information is considered as private in many scenarios. Protecting location information on mobile ad-hoc networks has attracted much research in past years. However, location information protection on social networks has not been paid much attention. In this paper, we present a novel location privacy protection approach on the basis of user messages in social networks. Our approach grants flexibility to users by offering them multiple protecting options. To the best of our knowledge, this is the first attempt to protect social network users' location information via text messages. We propose five algorithms for location privacy protection on social networks.

We present a high fidelity cognitive radio (CR) network emulation platform for wireless system tests, measure- ments, and validation. This versatile platform provides the configurable functionalities to control and repeat realistic physical channel effects in integrated space, air, and ground networks. We combine the advantages of scalable simulation environment with reliable hardware performance for high fidelity and repeatable evaluation of heterogeneous CR networks. This approach extends CR design only at device (software-defined-radio) or lower-level protocol (dynamic spectrum access) level to end-to-end cognitive networking, and facilitates low-cost deployment, development, and experimentation of new wireless network protocols and applications on frequency- agile programmable radios. Going beyond the channel emulator paradigm for point-to-point communications, we can support simultaneous transmissions by network-level emulation that allows realistic physical-layer inter- actions between diverse user classes, including secondary users, primary users, and adversarial jammers in CR networks. In particular, we can replay field tests in a lab environment with real radios perceiving and learning the dynamic environment thereby adapting for end-to-end goals over distributed spectrum coordination channels that replace the common control channel as a single point of failure. CR networks offer several dimensions of tunable actions including channel, power, rate, and route selection. The proposed network evaluation platform is fully programmable and can reliably evaluate the necessary cross-layer design solutions with configurable op- timization space by leveraging the hardware experiments to represent the realistic effects of physical channel, topology, mobility, and jamming on spectrum agility, situational awareness, and network resiliency. We also provide the flexibility to scale up the test environment by introducing virtual radios and establishing seamless signal

Traditionally, professionals have networked with others in their field through attending conferences, professional organizations, direct mailing, and via the workplace. Recently, there have been new possibilities to network with other professionals using the internet. This article looks at the possibilities that the internet offers for professional networking, particularly e-mailing lists, newsgroups and membership databases, and compares them against more traditional methods of professional networking. The different types of computer-mediated communication are discussed and their relative merits and disadvantages are examined. The benefits and potential pitfalls of internet professional networking, as it relates to the nursing profession, are examined. Practical advice is offered on how the internet can be used as a means to foster professional networks of academic, clinical or research interests.

technologies. Several years ago, when many of these optical networking research topics were first being investigated, they were the subject of controversial debate. The new techniques challenged many long-held concepts related to architecture and technology. However, today all major networking organizations are transitioning toward infrastructure that incorporates these new concepts. This progress has been assisted through the series of Optical Networking Testbed Workshops (ONT). The first (ONT1) outlined a general framework of key issues and topics and developed a series of recommendations (www.nren.nasa.gov/workshop7). The second (ONT2) developed a common vision of optical network technologies, services, infrastructure, and organizations (www.nren.nasa.gov/workshop8). Processes that allow for a common vision encourage widespread deployment of these types of resources among advanced networking communities. Also, such a shared vision enables key concepts and technologies to migrate from basic research testbeds to wider networking communities. The ONT-3 workshop built on these earlier activities by expanding discussion to include additional considerations of the international interoperability and of greater impact of optical networking technology on networking in general. In accordance with this recognition, the workshop confirmed that future-oriented research and development is indispensable to fundamentally change the current Internet architecture to create a global network incorporating completely new concepts. The workshop also recognized that the first priority to allow for this progress is basic research and development, including international collaborative activities, which are important for the global realization of interoperability of a new generation architecture.

We introduce a model for the emergence of innovations, in which cognitive processes are described as random walks on the network of links among ideas or concepts, and an innovation corresponds to the first visit of a node. The transition matrix of the random walk depends on the network weights, while in turn the weight of an edge is reinforced by the passage of a walker. The presence of the network naturally accounts for the mechanism of the "adjacent possible," and the model reproduces both the rate at which novelties emerge and the correlations among them observed empirically. We show this by using synthetic networks and by studying real data sets on the growth of knowledge in different scientific disciplines. Edge-reinforced random walks on complex topologies offer a new modeling framework for the dynamics of correlated novelties and are another example of coevolution of processes and networks.

We investigate a dynamic model of network marketing in a small-world network structure artificially constructed similarly to the Watts-Strogatz network model. Different from the traditional marketing, consumers can also play the role of the manufacturer's selling agents in network marketing, which is stimulated by the referral fee the manufacturer offers. As the wiring probability α is increased from zero to unity, the network changes from the one-dimensional regular directed network to the star network where all but one player are connected to one consumer. The price p of the product and the referral fee r are used as free parameters to maximize the profit of the manufacturer. It is observed that at α=0 the maximized profit is constant independent of the network size N while at α≠0, it increases linearly with N. This is in parallel to the small-world transition. It is also revealed that while the optimal value of p stays at an almost constant level in a broad range of α, that of r is sensitive to a change in the network structure. The consumer surplus is also studied and discussed.

Intermediate-scale (or `meso-scale') structures in networks have received considerable attention, as the algorithmic detection of such structures makes it possible to discover network features that are not apparent either at the local scale of nodes and edges or at the global scale of summary statistics. Numerous types of meso-scale structures can occur in networks, but investigations of such features have focused predominantly on the identification and study of community structure. In this p...

Network theory is rapidly changing our understanding of complex systems, but the relevance of topological features for the dynamic behavior of metabolic networks, food webs, production systems, information networks, or cascade failures of power grids remains to be explored. Based on a simple model of supply networks, we offer an interpretation of instabilities and oscillations observed in biological, ecological, economic, and engineering systems. We find that most supply networks display damped oscillations, even when their units--and linear chains of these units--behave in a nonoscillatory way. Moreover, networks of damped oscillators tend to produce growing oscillations. This surprising behavior offers, for example, a different interpretation of business cycles and of oscillating or pulsating processes. The network structure of material flows itself turns out to be a source of instability, and cyclical variations are an inherent feature of decentralized adjustments.
a new framework to quantify the information encoded in these networks and to answer a fundamental problem in network science: how complex are temporal and growing networks. Finally, we consider two examples of critical phenomena in interacting networks. In particular, on one side we investigate the percolation of interacting networks by introducing antagonistic interactions. On the other side, we investigate a model of political election based on the percolation of antagonistic networks. The aim of this research is to show how antagonistic interactions change the physics of critical phenomena on interacting networks. We believe that the work presented in these thesis offers the possibility to appreciate the large variability of problems that can be addressed in the new framework of temporal and interacting networks.

Practical and organizational reasons, e.g. problems of timing, and strain factors in private or professional life are cited predominantly when probands spontaneously utter their motives for the non-acceptance of an offer of psychotherapy. In the second place, a lack of insight into the necessity of this kind of treatment is indicated as motive for the rejection of a therapy offer. An exploration of the probands leads to a change in the frequently distribution of the motives uttered to refuse psychotherapeutic treatment. Basically, the differentiation of the answers increases (indication of more than one category of motives). A negative attitude to or fear of psychotherapy was indicated considerably more often, especially by women. Those--mostly male--probands, who had pointed out that a lack of insight into the necessity of psychotherapeutic treatment was the decisive factor for their non-acceptance of the therapy offer, adhered most consistently to their argumentation also after exploration. The statistical analysis of possible determinants for the different styles in which probands state the motives for their rejection revealed significant sex differences. These findings suggest that the uptake of psychotherapeutic treatment is also guided by sex role sterotypes.

Carbon nanomaterials have been investigated for various biomedical applications. In most cases, however, these nanomaterials must be functionalized biologically or chemically due to their biological inertness or possible cytotoxicity. Here, we report the development of a new carbon nanomaterial with a bioactive phase that significantly promotes cell adhesion. We synthesize the bioactive phase by introducing self-assembled nanotopography and altered nano-chemistry to graphite substrates using ultrafast laser. To the best of our knowledge, this is the first time that such a cytophilic bio-carbon is developed in a single step without requiring subsequent biological/chemical treatments. By controlling the nano-network concentration and chemistry, we develop platforms with different degrees of cell cytophilicity. We study quantitatively and qualitatively the cell response to nano-network platforms with NIH-3T3 fibroblasts. The findings from the in vitro study indicate that the platforms possess excellent biocompatibility and promote cell adhesion considerably. The study of the cell morphology shows a healthy attachment of cells with a well-spread shape, overextended actin filaments, and morphological symmetry, which is indicative of a high cellular interaction with the nano-network. The developed nanomaterial possesses great biocompatibility and considerably stimulates cell adhesion and subsequent cell proliferation, thus offering a promising path toward engineering various biomedical devices.

Climate has captured the attention of the public but its complexity can cause interested individuals to turn to opinion pieces, news articles or blogs for information. These platforms often oversimplify or present heavily interpreted or personalized perspectives. Data interactives are an extremely effective way to explore complex geoscience topics like climate, opening windows of understanding for the user that have previously been closed. Layering data onto maps through programs like GeoMapApp and the Earth Observer App has allowed users to dig directly into science data, but with only limited scaffolding. The interactive 'Polar Explorer: Sea Level Explorer App' provides a richly layered introduction to a range of topics connected to sea level rise. Each map is supported with a pop up and a short audio file of supplementary material, and an information page that includes the data source and links for further reading. This type of learning platform works well for both the formal and informal learning environment. Through science data displayed as map visualizations the user is invited into topics through an introductory question, such as "Why does sea level change?" After clicking on that question the user moves to a second layer of questions exploring the role of the ocean, the atmosphere, the contribution from the world's glaciers, world's ice sheets and other less obvious considerations such as the role of post-glacial rebound, or the mining of groundwater. Each question ends in a data map, or series of maps, that offer opportunities to interact with the topic. Under the role of the ocean 'Internal Ocean Temperature' offers the user a chance to touch to see temperature values spatially over the world's ocean, or to click through a data series starting at the ocean surface and diving to 5000 meters of depth showing how temperature changes with depth. Other sections, like the role of deglaciation of North America, allow the user to click and see change through
Networks are everywhere, from the Internet, to social networks, and the genetic networks that determine our biological existence. Illustrated throughout in full colour, this pioneering textbook, spanning a wide range of topics from physics to computer science, engineering, economics and the social sciences, introduces network science to an interdisciplinary audience. From the origins of the six degrees of separation to explaining why networks are robust to random failures, the author explores how viruses like Ebola and H1N1 spread, and why it is that our friends have more friends than we do. Using numerous real-world examples, this innovatively designed text includes clear delineation between undergraduate and graduate level material. The mathematical formulas and derivations are included within Advanced Topics sections, enabling use at a range of levels. Extensive online resources, including films and software for network analysis, make this a multifaceted companion for anyone with an interest in network sci...

Our dependence on networks - be they infrastructure, economic, social or others - leaves us prone to crises caused by the vulnerabilities of these networks. There is a great need to develop new methods to protect infrastructure networks and prevent cascade of failures (especially in cases of coupled networks). Terrorist attacks on transportation networks have traumatized modern societies. With a single blast, it has become possible to paralyze airline traffic, electric power supply, ground transportation or Internet communication. How, and at which cost can one restructure the network such that it will become more robust against malicious attacks? The gradual increase in attacks on the networks society depends on - Internet, mobile phone, transportation, air travel, banking, etc. - emphasize the need to develop new strategies to protect and defend these crucial networks of communication and infrastructure networks. One example is the threat of liquid explosives a few years ago, which completely shut down air travel for days, and has created extreme changes in regulations. Such threats and dangers warrant the need for new tools and strategies to defend critical infrastructure. In this paper we review recent advances in the theoretical understanding of the vulnerabilities of interdependent networks with and without spatial embedding, attack strategies and their affect on such networks of networks as well as recently developed strategies to optimize and repair failures caused by such attacks.
