Ontology Based Service Recommendation System for Social Network

The development of recommendation systems, such as traditional content-based, collaborative filtering and hybrid recommendation approaches have enabled the practical use of big data processing in WEB 3.0. In this paper, we propose an ontology based service recommendation system for social network. In this paper, implementation methods of the system are explained in detail. In order to extract user interests more exactly, the TF-IDF (term frequency-inverse document frequency) algorithm is improved according to the features of Micro logs and integrated with the Text Rank algorithm. Also, we have improved the Hownet based semantic similarity algorithm with the consideration of the density of sememe tree. Experimental results show that recommendation results of our system can well reflect the real interests of users, and the improved algorithms can make the results more accurate.
Efficient Trajectory Compression and Queries

Nowadays, there are ubiquitousness of GPS sensors in various devices collecting, storing and transmitting tremendous trajectory data. However, an unprecedented scale of GPS data has posed an urgent demand for not only an effective storage mechanism but also an efficient query mechanism. Line simplification in online mode, a kind of commonly used trajectory compression methods in practice, plays an important role to attack this issue. But for the existing algorithms, either their time cost is extremely high, or the accuracy loss after the compression is too much. To address this, we propose $\epsilon$-Region based Online trajectory Compression with Error bounded (ROCE for short), which makes the best balance among the accuracy loss, the time cost and the compression rate. In most previous work, each trajectory is seen as a sequence of discrete points for various queries. But it's not suitable when the queried trajectories have been compressed, because there may be hundreds of points discarded between each two adjacent points and the points in each compressed trajectory are quite sparse. To attack this issue, in this paper, each compressed trajectory is regarded as a sequence of continuous line segments, but not discrete points. And based on this, we propose a new trajectory similarity metric AL, an efficient index ASP-tree and two algorithms about how to process range queries and top-k similarity queries on the compressed trajectories. Extensive experiments have been done on real datasets and the results demonstrate superior performance of our methods.
Human Action Localization with Sparse Spatial Supervision

We introduce an approach for spatio-temporal human action localization using sparse spatial supervision. Our method leverages the large amount of annotated humans available today and extracts human tubes by combining a state-of-the-art human detector with a tracking-by-detection approach. Given these high-quality human tubes and temporal supervision, we select positive and negative tubes with very sparse spatial supervision, i.e., only one spatially annotated frame per instance. The selected tubes allow us to effectively learn a spatio-temporal action detector based on dense trajectories or CNNs. We conduct experiments on existing action localization benchmarks: UCF-Sports, J-HMDB and UCF-101. Our results show that our approach, despite using sparse spatial supervision, performs on par with methods using full supervision, i.e., one bounding box annotation per frame. To further validate our method, we introduce DALY (Daily Action Localization in YouTube), a dataset for realistic action localization in space and time. It contains high quality temporal and spatial annotations for 3.6k instances of 10 actions in 31 hours of videos (3.3M frames). It is an order of magnitude larger than existing datasets, with more diversity in appearance and long untrimmed videos.
Mobile micro screw pump with flow sensing capability for on-site flow control in microchannel device

This paper describes the development of a micro screw pump which can be installed anywhere where pumping is needed in a μ-TAS. We made this micro screw pump to let fluid flow at an extremely low flow rate with high response, and we also created a new method for on-site flow sensing by monitoring the position of the micro screw. The screw we use is made by microstereolithography with magnetically modified photo curable polymer previously reported in MEMS '09 [1]. We placed the micro screw inside a glass capillary and rotated it by an external magnetic field at high frequencies. Because of the screw's shape, it causes the surrounding fluid to be propelled forward. By decreasing the diameter of the tubing connected to the screw-housing capillary, we succeeded in producing extremely low flow rates. Since we use an electronic magnetic field to rotate the micro screw, we can realize a very high response when stopping the flow. We also pay attention to the position of screw which is influenced by three factors, the propulsive force, magnetic trap force, and static flow force, and we created a new method to monitor flow rate with knowing rotational frequency and position of screw.
Apprentissage actif dans les processus décisionnels de Markov partiellement observables L'algorithme MEDUSA

We study a problem inspired from robotics in which we want to find an optimal policy to learn a Partially Observable Markov Decision Process (POMDP) when the agent only has an imperfect model of its environment. To help the agent in its task we assume the availability of an external operator (an oracle), that can provide information about the underlying state. We present the algorithm MEDUSA, which improves an initial POMDP model using experimentation through the environment and a minimum number of queries. We also show how MEDUSA handles non-stationary environments and how it can withstand noise in the query answer.
Comparative genome mapping with mobile physical map landmarks

We describe a method for comparative macrorestriction mapping of the chromosomes of Escherichia coli strains. In this method, a series of physically tagged E. coli K-12 alleles serve as mobile landmarks for mapping DNAs from other strains. This technique revealed evidence of strain-specific chromosomal additions or deletions in a pathogenic isolate and can be applied to most strains, yielding information on genealogy as well as virulence. In theory, the same strategy can be used to map and compare genomic DNAs from a wide variety of species.
FINANCIAL LITERACY EDUCATION AND RETIREMENT PLANNING IN MALAYSIA

Lack of education in financial literacy would lead to fallacious retirement planning decisions among elderly people. Many elderly people are facing dilemma of not having sufficient money to maintain their living upon retirement and this problem is becoming worse over time. Thus, this qualitative study explores the financial literacy education of elderly people and the influence on retirement planning in Malaysia. Data for probing the influence of financial literacy education on financial retirement planning of elderly people in Malaysia were collected using semi-structured interview questions and document analysis. Data were collected from 10 elderly people with financial education background and have experience in dealing with financial planning for retirement from Klang Valley, Malaysia. Purposeful sampling technique was used to collect data and thematic analysis was used to interpret the data collected in this study. The results of this study indicated that financial literacy education along with demographic factors and financial attitude factors play a crucial role in financial retirement planning before retirement. The results further indicate that psychological factors like monetary goal-setting, early financial exposure and financial awareness affect elderly people in enhancing financial literacy education, which eventually influence financial retirement planning. In order to improve on the financial planning for retirement, policy makers and government need to implement financial literacy education policy to aid elderly people in financial planning and retire with financial freedom.
Rich Services — A SOA Pattern for Dynamic Change in Cyber-physical Systems

Abstract Cyber-physical systems (CPS) are changing the way we interact with the physical world. From automotive to manufacturing to logistics to power-grid to virtual command and control, we now see widespread application of integrated, software-intensive systems of sensor/actuator networks connected to backbone cyber-infrastructures. In this document we develop Rich Services as an architectural pattern suitable for systematically designing and implementing CPS, with particular emphasis on dynamic change. Zusammenfassung Cyber-physical systems (CPS) ändern unsere Interaktion mit der Welt auf fundamentale Weise. Integrierte, software-intensive Systeme, die Sensorik und Aktuatorik mit vernetzter, hochvirtualisierter IT Infrastruktur verbinden, sind inzwischen bei automobilen Anwendungen, industrieller Fertigung, Logistik, Energienetzen, bis hin zu virtuellen Steuerungssystemen gang und gäbe. In diesem Artikel entwickeln wir “Rich Services” als ein Architekturmuster, das für den systematischen Entwurf wie die Implementierung sich dynamisch verändernder CPS besonders geeignet ist.
[Plain radiograph and CT features of 112 patients with SARS in acute stage].

OBJECTIVE To retrospectively analyze the X-ray and CT features of patients with suggestive of SARS at the early stages. METHODS The study comprised 112 patients (43 men, 69 women; aged from 16 to 82 year) with clinically proved SARS. Chest radiograph was performed in all the patients and CT of thorax in 22 patients during the first week of the onset. RESULTS In the early stage, the most common findings were patchy ground-glass opacification (GGO) (79.5% on X-ray and 81. 8% on CT) and mixed lesions of GGO with irregular consolidation (21.4% on X-ray and 45.5% on CT) and/or granulomas (14.3% on X-ray and 27.3% on CT). A majority of lesions were located in the middle and lower field (70.9%) with peripheral distribution (69%). Other findings on CT included intralobular and interlobular septal thickening (carzy-paving pattern) (36.4%), bronchiectasis (18.2%) and small pleural effusion (22.7%). CONCLUSION Common radiologic findings of SARS are ground-glass opacification and mixed lesions of GGO with irregular consolidation and/or granulomas and lower location and peripheral distribution.
A new approach for the design of CMOS voltage buffers for switched-capacitor and gm-C filters

Buffers are widely employed as basic building blocks in time delay lines and in interfacing integrated circuits with the external world. This paper presents a new CMOS analog fully differential voltage buffer developed for minimum power consumption, large dynamic range and low harmonic distortion. Its design is based on the use of cross-coupled input differential pairs and internal current feedback. Two design approaches are proposed: one for switched-capacitor circuits and the other for gm-C circuits. Illustrative design examples are developed for a 0.35 - ″m″m CMOS technology using a power supply voltage of 2.5 V. Spice simulations using BSIM3 device models are shown to support the theory.
A Fault-Tolerant Content Addressable Network

In this paper, we propose a new method to enhance the fault-tolerance of the Content Addressable Network (CAN), which is known as a typical pure P2P system based on the notion of Distributed Hash Table (DHT). The basic idea of the proposed method is to introduce a redundancy to the management of index information distributed over the nodes in the network, by allowing each index to be assigned to several nodes, which was restricted to be one in the original CAN system. To keep the consistency among several copies of indices, we propose an efficient synchronization scheme based on the notion of labels assigned to each copy in a distinct manner. The performance of the proposed scheme is evaluated by simulation. The result of simulations indicates that the proposed scheme really enhances the fault-tolerance of the CAN system.
Asymmetric negative influence of cynicism and skepticism: a study of preventative communication

Abstract It has been known that skepticism and cynicism are similar with each other as part of a continuum from trust to distrust in the message and that both skeptics and cynics are typified by beliefs that they could be misled by the marketing communication. However, skepticism and cynicism differ from each other in the distrust in communication contents versus communication motives. Skeptics tend to search information to discern truth of the communication content while cynics who tend to infer a selfish motive behind the communication when they are pressured by others in authority. The present study emphasizes the difference between skeptics and cynics in responding to public and commercial communications, by focusing on the compliance with preventative communications. In general, literature finds that the increase in threat or fear level contributes to the persuasion of preventative communication. However, past studies also suggested that increasing the level of threat or fear may backfire. Given the controversy over the positive and negative effects of increases in the level of threat or fear, the present study compares the effect of threat-appeal communication on attenuating and accentuating the negative effects of skepticism and cynicism. Study one shows that, exposed to a public communication that lacks threat, cognitive elaboration on the message has a positive effect on compliance with the communication, only for skeptics. Study two shows that, in the context of public communication, increases in threat level attenuate the negative effect of skepticism on persuasion while they accentuate the negative effect of cynicism. Study three replicates study two in the context of commercial advertising. Extending the failure of threat appeal to persuade cynics, study four shows that the preventative communication employing a humor appeal on the threatening issue is effective in persuading cynics but not skeptics.
No. 01: Hungry Cities of the Global South

The recent inclusion of an urban Sustainable Development Goal in the Post-2015 UN Development Agenda represents an important acknowledgement of the reality of global urbanization and the many social, economic, infrastructural and political challenges posed by the human transition to a predominantly urban world. However, while the SDG provides goals for housing, transportation, land use, cultural heritage and disaster risk prevention, food is not mentioned at all. This discussion paper aims to correct this unfortunate omission by reviewing the current evidence on the challenges of feeding rapidly-growing cities in the Global South. The paper first documents the magnitude of the urban transition and the variety of indicators that have been deployed to measure the extent of food insecurity amongst urban populations. It then looks at the way in which urban food systems are being transformed by the advent of supermarkets (the so-called “supermarket revolution”) and the growth of the informal food economy. The final section of the paper examines the relationship between formal and informal food retail and asks whether the one is undermining the other or whether they co-exist in an uneasy, though symbiotic, relationship. Against this backdrop, the secondary purpose of the paper is to lay out a research agenda which will guide the Hungry Cities Partnership as it attempts to give greater global prominence to the critical but neglected issue of urban food systems and food insecurity.
Lesbian Parents Negotiating the Health Care System in Australia

Twenty Australian lesbian-parented families were interviewed in multigenerational family groups about the interface between their public and private worlds. Experiences of the health care bureaucracy were difficult, whereas many participants found individual providers to be approachable and caring. Three strategies were used for disclosure of their sexual orientation to health care providers: private, proud, and passive. Influences on the strategy used included family formation, role of the non-birth parent, geographic location, and expected continuity of care. Parents displayed a high degree of thoughtful planning in utilizing their preferred disclosure strategy in order to optimize safety, particularly for their children.
Management of atrial fibrillation in the Greek healthcare setting.

INTRODUCTION Atrial fibrillation (AF) is the most frequent cardiac arrhythmia in the general population. AF management patterns have important implications for both the patient's quality of life and the utilisation of healthcare resources. This study aimed to investigate the management pattern of AF among cardiologists in the Greek healthcare setting. METHODS In order to construct the outpatient management model, the patient record data of 149 geographically distributed physicians were used. Data on inpatient resource utilisation were obtained from a consensus panel of AF experts. RESULTS 89.6% of AF patients were treated with pharmacological agents, whereas 5.2% of patients were treated with invasive methods and 5.2% received no treatment. In 59.5% of patients under pharmacological therapy, a rhythm-control strategy was implemented, whereas for the remaining 40.5% of patients a rate-control strategy was selected. Class Ic and III antiarrhythmic agents constituted the main therapeutic choices in the rhythm-control strategy, whereas -blockers and digoxin were the most frequently prescribed agents in the rate-control strategy. 89.0% of the patients on pharmacological rhythm control, 91.3% of those on pharmacological rate control, and 100.0% of patients undergoing invasive treatment received antithrombotic medication. CONCLUSIONS Elimination of the rhythm disturbance and rhythm management are the dominant choices in AF management made by cardiologists in Greece. AF management requires close patient monitoring, as is reflected in the frequency of follow-up visits and laboratory tests performed, irrespective of treatment approach. Hospitalisations due to AF or related comorbidities are also common.
Becoming a nurse: a meta-study of early professional socialization and career choice in nursing.

AIM This paper is a report of a meta-study of early professional socialization and career choice in nursing. BACKGROUND The current and growing shortage of nurses is a global issue, and nursing recruitment and retention are recognized priorities internationally. The future of nursing will lie in the ability to recruit and retain the next generation to the profession. DATA SOURCES Studies were identified through a search of the CINAHL, PsycInfo, Sociological Abstracts, PubMed; Medline and Embase databases from 1990 to 2007. REVIEW METHODS Studies were included if they gave insight into the experience of choosing nursing as a career, used qualitative methodology and methods, and were published in English. Analysis was undertaken using Paterson et al.'s framework for qualitative meta-synthesis. RESULTS Ten primary studies were included in the review. Their methodologies included: ethnography (4); descriptive qualitative (3); grounded theory (2); and phenomenology (1). The location of the research was Canada (3), United Kingdom (2), United States of America (2), Australia (1), Japan (1) and Sweden (1). Three main themes were identified: influence of ideals; paradox of caring and role of others. CONCLUSION Career choice and early professional socialization are influenced by multiple factors. In future recruitment and retention strategies to address the critical nursing shortage, it is important to consider the role of mentors, peers and role models in the formulation of career expectations, and career choice decisions. It is also necessary to consider the role of mentors, peers and role models in the formulation of career expectations, and career choice decisions.
Escalation of commitment : evaluating project termination behaviour of masters of engineering management students

In this study we presented 180 Masters of Engineering Management students with five scenarios of a troubled project at different phases in the project lifecycle. Each scenario presented specific economic parameters about the return on investment if the project is completed, and the salvage value should the project be stopped before completion. The research showed that, despite their project management education, the students exhibited substantial escalation of commitment behaviour, and the majority chose to continue with the project in the face of clear evidence that the project would fail.

Étude de la variabilité des contributions de nutriments à un réseau métabolique : modélisation, optimisation et application en nutrition

Nous developpons une approche generique pour comprendre comment differents regimes alimentaires peuvent influencer la qualite et la composition du lait. Cette question s'integre dans le cadre du Flux Balance Analysis (FBA), qui consiste a analyser un reseau metabolique en optimisant un systeme de contraintes lineaires. Nous avons propose une extension du FBA pour analyser la transformation des nutriments en integrant des hypotheses biologiques utilisees par differents modeles numeriques dans un modele generique de la glande mammaire. Notre methode permet de quantifier les precurseurs qui interviennent dans la composition des sorties du systeme, en calculant des contributions des entrees dans les sorties [AIO]. A l'aide de cette approche, nous avons montre que la transformation des nutriments du lait ne peut pas etre modelisee par l'optimisation d'une combinaison lineaire des flux des reactions sur un modele du metabolisme mammaire. Pour etudier plus precisement la flexibilite d'un reseau metabolique, nous avons propose un algorithme efficace de recherche locale pour calculer les valeurs extremales des coefficients des AIOs. Cette approche permet de discriminer les traitements sans formuler d'hypotheses sur le comportement interne du systeme.
Isolation and determination of deoxynivalenol by reversed-phase high-pressure liquid chromatography

Deoxynivalenol (DON) is a mycotoxin produced by food contamination. It is a pharmacologically active compound that acts on the serotonin receptor, leading to several neuroendocrine and hematological disorders. In this article we describe a simple, accurate, and sensitive method for the quantification of DON. DON was quantified using a Phenomenex® ODS analytical C18 column (150 mm × 46 mm, 5 μm) with a mobile phase composed of mixture of water-acetonitrile-methanol (5:4:1, v/v/v) at a flow rate of 1.5 ml/min and at 254 nm in an ultraviolet (UV) detector The method has been validated with isolated samples of DON and provides a tool for the control of substandard and counterfeit commercial food products.
