Opinion mining: A study on semantic orientation analysis for online document

As a result of advance in technology, there now exist a large amount of online documents in the form of surveys or called reviews. Most of the previous work on text classification is focusing on sentiment text classification. Sentiment classification requires the knowledge data of vocabulariespsila semantic meaning and the relationships between the vocabularies. In this paper, sentiment features of text were divided into characteristic words and phrases, which were extracted from the training data. The method combining HowNet with sentiment classifier was proposed. It computed semantic similarity of characteristic words, phrases with tagged words in HowNet, and it adopted the positive and negative terms as features of sentiment classifier. In the test, a sentiment classifier was designed to compare with the other methods. Evaluation results show the effectiveness of our method.
Lectin-Like Oxidized LDL Receptor-1 Is an Enhancer of Tumor Angiogenesis in Human Prostate Cancer Cells

Altered expression and function of lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) has been associated with several diseases such as endothelial dysfunction, atherosclerosis and obesity. In these pathologies, oxLDL/LOX-1 activates signaling pathways that promote cell proliferation, cell motility and angiogenesis. Recent studies have indicated that olr1 mRNA is over-expressed in stage III and IV of human prostatic adenocarcinomas. However, the function of LOX-1 in prostate cancer angiogenesis remains to be determined. Our aim was to analyze the contribution of oxLDL and LOX-1 to tumor angiogenesis using C4-2 prostate cancer cells. We analyzed the expression of pro-angiogenic molecules and angiogenesis on prostate cancer tumor xenografts, using prostate cancer cell models with overexpression or knockdown of LOX-1 receptor. Our results demonstrate that the activation of LOX-1 using oxLDL increases cell proliferation, and the expression of the pro-angiogenic molecules VEGF, MMP-2, and MMP-9 in a dose-dependent manner. Noticeably, these effects were prevented in the C4-2 prostate cancer model when LOX-1 expression was knocked down. The angiogenic effect of LOX-1 activated with oxLDL was further demonstrated using the aortic ring assay and the xenograft model of tumor growth on chorioallantoic membrane of chicken embryos. Consequently, we propose that LOX-1 activation by oxLDL is an important event that enhances tumor angiogenesis in human prostate cancer cells.
An Empirical Investigation of Capability Factors Affecting Strategic Information System Planning Success

Strategic information systems planning SISP is more difficult in today's world of rapid change and uncertainty. The dynamic changes in the environment require a fit between SISP and internal resources of the firm. A need exists to study SISP success based on a broad set of organizational attributes of firm. In this regard, a resource-based view RBV has gained increasing dominance in the strategic management field and views organization as a bundle of resources. Reviewing SISP literature reveals little on what the essential Information Systems' formulation IS capabilities for SISP are and how they affect success. In this study, the relationship between capability factors and SISP success are explored. Capability factors were compiled through literature review and validated by using interviews. Hypotheses were developed and tested utilizing responses collected from 167 medium to large Iranian organizations. Using PLS for data analysis, the results show the important role of capability factors in SISP success that could be beneficial for both practice and research.
Prioritizing Health: A Systematic Approach to Scoping Determinants in Health Impact Assessment

The determinants of health are those factors that have the potential to affect health, either positively or negatively, and include a range of personal, social, economic, and environmental factors. In the practice of health impact assessment (HIA), the stage at which the determinants of health are considered for inclusion is during the scoping step. The scoping step is intended to identify how the HIA will be carried out and to set the boundaries (e.g., temporal and geographical) for the assessment. There are several factors that can help to inform the scoping process, many of which are considered in existing HIA tools and guidance; however, a systematic method of prioritizing determinants was found to be lacking. In order to analyze existing HIA scoping tools that are available, a systematic literature review was conducted, including both primary and gray literature. A total of 10 HIA scoping tools met the inclusion/exclusion criteria and were carried forward for comparative analysis. The analysis focused on minimum elements and practice standards of HIA scoping that have been established in the field. The analysis determined that existing approaches lack a clear, systematic method of prioritization of health determinants for inclusion in HIA. This finding led to the development of a Systematic HIA Scoping tool that addressed this gap. The decision matrix tool uses factors, such as impact, public concern, and data availability, to prioritize health determinants. Additionally, the tool allows for identification of data gaps and provides a transparent method for budget allocation and assessment planning. In order to increase efficiency and improve utility, the tool was programed into Microsoft Excel. Future work in the area of HIA methodology development is vital to the ongoing success of the practice and utilization of HIA as a reliable decision-making tool.
Relationships of involvement and interdependent happiness between domestic and international Japanese masters games tourists

ABSTRACT The purpose of this research note is to examine (a) how involvement with masters games participation is associated with interdependent happiness among Japanese masters athletes, and (b) how the relationship differs between Japanese sport tourists who have competed at domestic and international masters games events. A questionnaire survey was conducted at the International Japan Masters Athletics Championships and, based on the experiences of international masters games athletes, 169 and 96 Japanese study participants were categorized as the domestic and international group, respectively. Results of multiple regression analyses indicated that the attraction dimension of involvement was positively related to interdependent happiness for both groups, whereas the social bonding dimension of involvement was positively related to interdependent happiness only for the domestic group. Our research note suggests that masters games promotion as well as health promotion through masters sports need to consider such similarity and difference between domestic and international sport tourists.

WIDER Working Paper No . 2013 / 009 Evaluating antipoverty transfer programmes in Latin America and sub-Saharan Africa Better policies ? Better politics ?

The paper provides a comparative analysis of the incidence of evaluation methods in antipoverty transfer programmes in Latin America and sub-Saharan Africa. The paper identifies two broad explanations for the incidence of evaluation in antipoverty transfer programmes in developing countries, one emphasizing the advantages of a shift towards evidence-based development policy, and a second explanation emphasizing political factors. The paper assesses their relevance in the context of Latin American and sub-Saharan African countries with a view to throwing light on whether the evaluation of antipoverty transfer programmes will lead to an improved effectiveness of the relevant government agencies.
Cross Validation of the 20-m Shuttle Run Test for Children and Adolescents with Mental Retardation

We cross validated the 20-m shuttle run test of aerobic capacity in children and adolescents with mild and moderate mental retardation (MR) using the population specific formula of Fernhall et al. (1998). Nine boys and 8 girls (age = 13.7 yr) completed a maximal treadmill protocol (measured VO2peak) and a 20-m shuttle run (predicted VO2peak). The measured peak oxygen consumption (VO2peak) was 39.4 ml kg-1 min-1. The relationship between measured and predicted VO2peak was r = . 86 with an SEE of 6.2 ml kg-1 min-1. Multiple regression and Bland-Altman analyses showed that there was little bias, but the Bland-Altman analysis indicated highly variable limits of agreement (Bland & Altman 1986). Thus, the traditional approach (regression analysis) to concurrent validity revealed that the 20-m shuttle run is a valid indicator of VO2peak in these participants. The accuracy of prediction (Bland & Altman, 1986), however, was lower than expected in a population without MR.
Chemical composition modulates the adverse effects of particles on the mucociliary epithelium

OBJECTIVE: We compared the adverse effects of two types of real ambient particles; i.e., total suspended particles from an electrostatic precipitator of a steel mill and fine air particles from an urban ambient particulate matter of 2.5 µm, on mucociliary clearance. METHOD: Mucociliary function was quantified by mucociliary transport, ciliary beating frequency and the amount of acid and neutral mucous in epithelial cells through morphometry of frog palate preparations. The palates were immersed in one of the following solutions: total suspended particles (0.1 mg/mL), particulate matter 2.5 µm 0.1 mg/mL (PM0.1) or 3.0 mg/mL (PM3.0) and amphibian Ringer's solution (control). Particle chemical compositions were determined by X-ray fluorescence and gas chromatography/mass spectrometry. RESULTS: Exposure to total suspended particles and PM3.0 decreased mucociliary transport. Ciliary beating frequency was diminished by total suspended particles at all times during exposure, while particulate matter of 2.5 µm did not elicit changes. Particulate matter of 2.5 µm reduced epithelial mucous and epithelium thickness, while total suspended particles behaved similarly to the control group. Total suspended particles exhibited a predominance of Fe and no organic compounds, while the particulate matter 2.5 µm contained predominant amounts of S, Fe, Si and, to a lesser extent, Cu, Ni, V, Zn and organic compounds. CONCLUSION: Our results showed that different compositions of particles induced different airway epithelial responses, emphasizing that knowledge of their individual characteristics may help to establish policies aimed at controlling air pollution.
Estimating forest biomass in the USA using generalized allometric models and MODIS land products

Spatially‐distributed forest biomass components are essential to understand carbon cycle and the impact of biomass burning emissions on air quality. We estimated the density of forest biomass components (foliage biomass, branch biomass, and aboveground biomass) at a spatial resolution of 1 km across the Contiguous United States using foliage‐based generalized allometric models and Moderate‐Resolution Imaging Spectroradiometer (MODIS) land data. The foliage biomass for each forest type was calculated from MODIS leaf‐area indices, land cover types, and vegetation continuous fields. The foliage‐based models were developed using available diameter‐based allometric equations and used to estimate branch biomass and aboveground biomass. The resultant aboveground biomass density matches well with the data from Forest Inventory and Analysis program at both state and pixel levels.

The impairments of sensorimotor hand functions in stroke patients - the comparison of the results of a clinical assessment and the assessment utilizing the standard tests (a case study)

The impairments of sensorimotor hand functions after a stroke have a negative impact on the subject's interaction with external settings and on performing common daily and working activities and thus on the quality of his or her life (Carey, 1995). Since the structure and function of the cerebral cortex is capable of after stroke modifications, new therapies are being looked for that support the desirable plasticity of the central nervous system to the maximum. The main condition for a successful treatment is a reliable target focused examination of all hand functions affected by the stroke. This requires both a differentiated and complex examination. This study presents the results and experience of treating patients hospitalized after a stroke. The impaired motor and somatosensory functions have been assessed through somatosensory and manipulation tests. In three case studies, the differences are pointed out between the results of the clinical neurological hand examination and the functional hand examination. Both examinations use target focused specialized tests.
The Long Run , Dynamic Impacts of Technology Spillovers and Amenities on Rural-Urban Migration Behavior

In this paper a two period overlapping generation model with an urban and rural region is developed where the number of high skill individuals working in each region is determined endogenously. The basic model is modified to examine how migration behavior reacts to: 1) a knowledge externality introduced in the urban employment sector; and 2) introduction of rural amenities and the effect of an increase in amenity benefits on migration behavior. In the first case it is found the knowledge externality, which is only realized by high skill and educated individuals, results in the unambiguous movement of these high skill workers to the urban region, a further explanation of the so called “brain drain” effect. However, in the case of amenity improvements the result is ambiguous. In the presence of improved amenities in rural areas, high skill workers generally migrate to rural areas at the high steady state, but in the low steady state equilibrium actually migrate to urban areas with less amenities. This last, less intuitive, result is due likely to a tradeoff between wages and amenities that favors higher urban wages in the low steady state.
Efficient mapping on FPGA of a Viterbi decoder for wireless LANs

In this paper an optimized hardware implementation on FPGA of a Viterbi decoder is presented for WLAN. A fixed-point analysis is made and its performance is compared with a soft decision decoding floating point model with CSI weight. Only 6 bits are needed to perform the soft quantification and 7 bits to the CSI, in order to maintain the performance of the floating point model. A normalization method is proposed to increase the throughput of the decoder, being possible to decode 172 Mbps when it is implemented in a Virtex 2 device. Power consumption results of the decoder implementation are presented for Hiperlan/2 maximum rate. Moreover, it has been shown that it is possible to reduce the power consumption disabling the unnecessary hardware depending on the WLAN modes.
Supervised and Dynamic Neuro-Fuzzy Systems to Classify Physiological Responses in Robot-Assisted Neurorehabilitation

This paper presents the application of an Adaptive Resonance Theory (ART) based on neural networks combined with Fuzzy Logic systems to classify physiological reactions of subjects performing robot-assisted rehabilitation therapies. First, the theoretical background of a neuro-fuzzy classifier called S-dFasArt is presented. Then, the methodology and experimental protocols to perform a robot-assisted neurorehabilitation task are described. Our results show that the combination of the dynamic nature of S-dFasArt classifier with a supervisory module are very robust and suggest that this methodology could be very useful to take into account emotional states in robot-assisted environments and help to enhance and better understand human-robot interactions.
The Indiana University Telephone-Based Assessment of Neuropsychological Status: A new method for large scale neuropsychological assessment

Sensitive measures of neuropsychological function were adapted to a telephone administration format for use in a large survey of quality of life in breast cancer survivors (BCS). Healthy controls (HC) and BCS were recruited from the community and administered the same neuropsychological test battery on two occasions separated by 1 week. Subjects were randomly assigned to conditions, stratified by diagnosis: In-person at Time-1 and In-person at Time-2 (P-P); Telephone at Time-1 and Telephone at Time-2 (T-T); T-P; and P-T. Four cognitive (Rey Auditory Verbal Learning Test, Controlled Oral Word Association, Digit Span, Symbol Digit) and two self-report measures (Squire Memory Self-Report Scale, Center for Epidemiological Studies Depression Scale) were used. The 106 subjects were randomized (54 HC and 52 BCS). Test–retest reliabilities (intraclass correlations) did not differ significantly by condition across the cognitive or self-report measures and ranged from moderate to near perfect (r's .43–.93; p's < .05). Mean scores at Time-1, practice effects (Time-1 to Time-2), and standard errors of measurement were comparable between In-person and Telephone administration formats. Results suggest that memory, attention, information processing speed, verbal fluency, and self-report of mood and memory can be measured reliably and precisely over the telephone.

Metformin Treatment Has No Beneficial Effect in a Dose-Response Survival Study in the SOD1G93A Mouse Model of ALS and Is Harmful in Female Mice

Background Amyotrophic Lateral Sclerosis (ALS) is a devastating neurological disorder characterized by selective degeneration of upper and lower motor neurons. The primary triggers for motor neuron degeneration are unknown but inflammation, oxidative stress and mitochondrial defects have been identified as potential contributing factors. Metformin is an anti-type II diabetes drug that has anti-inflammatory and anti-oxidant properties, can bring about mitochondrial biogenesis and has been shown to attenuate pathology in mouse models of Huntington's disease and multiple sclerosis. We therefore hypothesized that it might increase survival in the SOD1G93A murine model of ALS. Methodology/Principal Findings Treatment of male and female SOD1G93A mice (n = ≥6 per sex) with 2 mg/ml metformin in the drinking water from 35 days, resulted in a significant increase in motor unit survival, as measured by in vivo electrophysiology at 100 days, in male EDL muscles (24+/−2 vs. 14+/−2 motor units, p<0.005) and female TA muscles (21+/−1 vs. 15+/−2 motor units, P = 0.0134). We therefore continued to test the effect of 0.5, 2 and 5 mg/ml metformin in the drinking water from 35 days on disease onset and progression (identified by twice weekly determination of weight and neurological score) as well as survival in male and female SOD1G93A mice (n = ≥14 per sex). Results for all groups were compared using Kaplan-Meier time to event analyses. In this survival study, metformin was unable to reduce pathology at any dose and had an unexpected dose-dependent negative effect on the onset of neurological symptoms (P = 0.0236) and on disease progression (P = 0.0362) in female mice. Conclusions/Significance This study suggests that metformin is a poor candidate for clinical trial in ALS patients and that the possibility of harmful effects of metformin in female ALS patients with type II diabetes should be investigated.
Convergence Analysis for Sequential Monte Carlo Receivers in Communications Applications

Recently, sequential Monte Carlo methods have been used in the telecommunications field, finding application in receiver design. Several properties of these receivers make their designs very attractive. These receivers do not require channel state information or training. Therefore, they are bandwidth efficient and no communication bandwidth needs to be wasted on training. The receivers are optimal in the sense that they achieve a minimum symbol error rate regardless of the noise distribution, nonlinearities in the system, or distribution of the transmitted symbol. Moreover, these receivers are capable of producing soft-information outputs, which enables the designer to utilize iterative receiver architectures for near-optimal performance. In this work we investigate the convergence properties of these algorithms when utilized in various types of receivers. We quantify the convergence rate. We describe how various parameters (e.g., noise power, channel fading rate, etc) and factors (e.g., state-space model mismatch) affect the convergence rate and point out the factors that should be improved first to gain speed and accuracy in the convergence
A Self-Adaptable Approach for Easing the Development of Grid-Oriented Services

The Service-Oriented Architecture (SOA) leverages the service abstraction to enable the development of modular, loose-coupled and distributed applications. In order to use such an architecture, service-based applications directly rely on services or compose them for conceiving new functionalities. In spite of these capabilities, they do not support the development of services which need high-performance computing. Grid computing offers an infrastructure for high-performance computing which is based on the sharing of distributed, low-cost and heterogeneous resources in large-scale. Thus, grids can be used to satisfy these high-performance service requirements. This work aims at easing the development of grid-oriented services. The iPOJO service-component model is used to propose an architecture that automatically manages job submission for services. This architecture is based on Dynaco (Adaptation for Components) and the XtreemOS grid operating system.
Framework for Natural Landmark-based Robot Localization

In this paper we present a framework for vision-based robot localization using natural planar landmarks. Specifically, we demonstrate our framework with planar targets using Fern classifiers that have been shown to be robust against illumination changes, perspective distortion, motion blur, and occlusions. We add stratified sampling in the image plane to increase robustness of the localization scheme in cluttered environments and on-line checking for false detection of targets to decrease false positives. We use all matching points to improve pose estimation and an off-line target evaluation strategy to improve a priori map building. We report experiments demonstrating the accuracy and speed of localization. Our experiments entail synthetic and real data. Our framework and our improvements are however more general and the Fern classifier could be replaced by other techniques.
