Opinion Extraction From Online Blogs And Public Reviews

The explosion of Web based user generated reviews has caused the emergence of Opinion Mining (OM) applications for knowing and analyzing the users.opinions toward a product, service, and policy. Opinion mining is getting popular due to rapid growth of web users, increasing number of online discussion forums, and other social media sites.Opinion mining is the process of determining the feelings or opinions of other people about services, politics, products and policies. However, due to the economic importance of these opinions, there is a growing trend of developing efficient and effective opinion mining systems.The main motivation of this thesis is to extract opinion from online blogs and user reviews using lexicon based approach.This work focuses on the development of lexicon based improved term weighting method for polarity classification at sentence level.The polarity lexicons often play a pivotal role in polarity classification of OM, indicating the positivity and negativity of a term along with the numeric score. However, the commonly available domain independent lexicons are not an optimal choice for all domains in OM applications, as polarity of a term changes from one domain to other, and such lexicons do not contain the correct polarity of a term for every domain. In this work, focus is lexicon based polarity classification by adapting a domain dependent polarity lexicon from set of labeled user reviews and domain independent lexicon, and propose a unified learning framework based on information theory concepts that can assign the terms with correct polarity (+ive, -ive) scores.The comparative results obtained from experiments show that proposed method outperforms the other baseline methods (e.g. machine learning methods) and achieves an average accuracy of 79% on word level and 81% at sentence level.The quantitative evaluation of proposed method against baseline methods shows that, (i) for a specific domain proposed method can provide a sufficient coverage of required opinionated text; (ii) adapted domain-specific lexicons have achieved improved performance in a real world and manually built datasets; (iii) polarity classification performance can be improved significantly with resulting adapted lexicon and (iv) threshold adjustment gives increased accuracy for polarity classification.The proposed framework is quite generalized and capable of classifying the opinionated text in any domain.
Perceptions and assessment of risk factors in Schistosoma haematobium infection in Buruku and Katsina-Ala Local Government Areas of Benue State-Nigeria

Schistosomiasis is one of the neglected diseases in tropical Africa that continues to plague inhabitants of sub-urban and rural areas where there are little or no safe water outlets. This study investigated urinary schistosomiasis infection in relation to knowledge, attitudes and practices of people in Buruku and Katsina-Ala Local Government Areas of Benue State, Nigeria. Using standard parasitological method (Filtration technique) to examine the urine, 335 (44.66%) were infected with Schistosoma haematobium eggs out of the 750 urine samples examined from school children and communities. Questionnaires were administered to each participant to collect information on socio-demographic data, knowledge on the causes of urinary schistosomiasis and risk factors in Schistosoma haematobium infection. Children of farmers recorded the peak of infection with 159 (24.37%). Inhabitants of the area mostly linked the disease to other causes like drinking dirty water 195(29.63%) among whose 115 (17.47%) were infected, playing in water 118 (17.93%) among whose 67 (10.18%) were infected, eating unripe fruits 72 (10.98%) among whose 30 (4.00%) were infected. Subjects’ knowledge about the role that fresh water snails play in transmission was low 38 (5.77%). 116 (25.22%) were recorded not having any idea of the cause of the disease and 70 (9.33%) were found infected. Activities like swimming, bathing/playing in water, washing and collection of edible snails from stream, ponds or river significantly correlated with the prevalence of Schistosoma haematobium infection (P < 0.01) and could be identified as risk factors in the area. There is an urgent need for the launching of a schistosomiasis control programme and development of human resources and materials for health education to decrease the frequency of water contact activities.
HIF2α cooperates with RAS to promote lung tumorigenesis in mice (Journal of Clinical Investigation (2009) 119, (2160-2170) doi:101172/JCI38443)

Members of the hypoxia-inducible factor (HIF) family of transcription factors regulate the cellular response to hypoxia. In non–small cell lung cancer (NSCLC), high HIF2α levels correlate with decreased overall survival, and inhibition of either the protein encoded by the canonical HIF target gene VEGF or VEGFR2 improves clinical outcomes. However, whether HIF2α is causal in imparting this poor prognosis is unknown. Here, we generated mice that conditionally express both a nondegradable variant of HIF2α and a mutant form of Kras (KrasG12D) that induces lung tumors. Mice expressing both Hif2a and KrasG12D in the lungs developed larger tumors and had an increased tumor burden and decreased survival compared with mice expressing only KrasG12D. Additionally, tumors expressing both KrasG12D and Hif2a were more invasive, demonstrated features of epithelial-mesenchymal transition (EMT), and exhibited increased angiogenesis associated with mobilization of circulating endothelial progenitor cells. These results implicate HIF2α causally in the pathogenesis of lung cancer in mice, demonstrate in vivo that HIF2α can promote expression of markers of EMT, and define HIF2α as a promoter of tumor growth and progression in a solid tumor other than renal cell carcinoma. They further suggest a possible causal relationship between HIF2α and prognosis in patients with NSCLC.
An Efficient Method for Automatic Generation of Labanotation Based on Bi-Directional LSTM

Labanotation uses a variety of graphic symbols to analyse and record human movements accurately and flexibly, which is an important means to protect traditional dance. In this paper, we introduce an efficient method for automatic generation of Labanotation from motion capture data by identifying human movements with bidirectional LSTM network (Bi-LSTM). Up to our knowledge, this is the first time that Bi-LSTM network has been introduced to the field of Labanotation generation. Compared with previous methods, Bi-LSTM used in our human movements recognition system learns context information for sequential data from not only the past but also the future directions. Combined with a newly designed discriminative skeleton-topologic feature, our approach has the ability to generate more accurate Labanotation than previous work. Experiment results on two public motion capture datasets show that our method outperforms state-of-the-art methods, demonstrating its effectiveness.
A study on prevalence of postpartum depression and correlation with risk factors

Background: Postpartum depression (PPD) is a depressive disorder, also known as postnatal depression. Despite responsiveness to treatment and serious consequences if untreated, PPD often remains unrecognized. This study aims to study the prevalence of PPD and to correlate risk factors associated with it. Materials and Methods: It was a cross-sectional study in Departments of OBGY, Pediatrics, and Psychiatry in a tertiary care hospital. Two hundred and fifty consecutive women, 1–6 weeks postpartum attending the above departments, were included after written informed consent. A specially designed semi-structured pro forma was used for correlation of various risk factors. Edinburgh Postnatal Depression Scale was used for diagnosing PPD. Results: In our study, we found that 20.4% of the women evaluated suffered from PPD. Significant risk factors for PPD included age below 30 years, financial dependence, positive family history of psychiatric illness and PPD, previous girl child, unwanted pregnancy, pressure to have a male child, and complications during pregnancy and delivery. Domestic violence, substance abuse in husband, and relationship issues also increased the risk. Conclusion: Considerable prevalence of PPD is found across various cultures. Prevention of risk factors is useful in primary prevention of PPD. In the future, our study can be used for screening females with high risk for developing PPD so that more intense interventions can be applied.
The liver

Liver fructose-1,6-bisphosphatase (FBPase) is a regulatory enzyme in gluconeogenesis that is elevated by obesity and dietary fat intake. Whether FBPase functions only in glucose metabolism or has other metabolic roles is currently unclear. In our recently published study, we examined the importance of liver FBPase in body weight regulation by performing a series of comprehensive physiological and biochemical assessments of energy balance and specific intervention studies in our transgenic mouse line that overexpresses FBPase specifically in the liver. Compared with negative littermates, these FBPase transgenic mice weighed 10% less, had 50% less adiposity, ate 15% less food but did not have altered energy expenditure. Increased circulating leptin and cholecystokinin levels, elevated fatty acid oxidation and reduced appetite stimulating neuropeptides, neuropeptide Y (NPY) and agouti-related peptide (AGRP), underpinned this phenotype. Blocking the action of FBPase returned food intake and body weight to those of the negative littermates. Our study is the first to identify liver FBPase as a previously unknown regulator of appetite and adiposity. Importantly, this work recognizes the liver as an important organ in appetite and body weight regulation. This commentary will provide further insight and expand on this novel concept that the liver does in fact play an important role in adiposity.
Short-time Fourier transform analysis of the phonocardiogram signal

In this paper, we present results of the PCG (phonocardiogram) signal analysis using the STFT (Short-Time Fourier Transform). Because of the nonstationarity of the PCG signal, it is important to maintain an analysing time window as short as possible to guaranty the stationarity hypothesis over small analysed segments. This will reduce the frequency resolution of the resulting spectrogram. However by adjusting the sliding time window, we can reach an acceptable result. The spectrogram is calculated by using first, short length sliding window to generate a temporal representation of the PCG, then longer length sliding window in order to generate a spectral representation of the PCG power. The resolution in such representations depend directly on the sliding window length. The temporal representation allows heart sounds and cardiac cycle durations to be measured. Whereas the spectrum, assuming a good frequency resolution, allows spectral characterisation of each heart sound. The results we obtained on normal PCG signal, show that the STFT analysis provides a clear comprehension of the cardiac events when the spectra are represented in the time-frequency scale basis. Such results confirm the normal aspects of the analysed PCG signal.
Characterization of homogenous TM nonlinear waveguide sensors

This work is devoted on a three-layer sensor bounded from one side by a nonlinear clad of intensity dependent refractive index. A normalized analysis of sensitivity of this configuration and the condition to maximize this sensitivity is introduced. Behavior of sensing sensitivity is accounted for through power flow and cut-off considerations. We establish a method of determining the proper dimensioning of the sensor to execute its maximum sensitivity. We found that the sensitivity is higher in nonlinear sensors than in linear case in spite of appearing at lower wave guiding widths so that nonlinear sensors are advisable in accurate sensing.
Control of articulated vehicle for mining applications: modeling and laboratory experiments

The paper presents the theoretical analysis and experimental results of path tracking control of a class of vehicles widely used in underground mining operations. A vehicle consists of the front and rear units hinged together, where each unit has only one pair of nonsteerable wheels. Steering is performed by changing the angle between the front and rear units by means of a (pair of) hydraulic cylinders (linear actuators). In operation this vehicle moves in either forward or backward directions. Path tracking control problem is of the main importance in order to follow the relatively narrow mining corridors. It consists of using the sensory information to measure the deviations in position and orientation from the path to be followed. Based upon these two tracking errors a feedback system must govern the appropriate steering action.
Profile of Caregivers of Institutionalized Elders

Introduction: The aging process of the population causes several transformations in the social, cultural and health context. The demand for gerontological care increases and, due to that, homes for the aged emerge as an alternative housing for the elderly who do not have enough support at this new life stage or for those who opt to live there. Objective: This study aimed at describing the profile of caregivers of elderly people who live in homes for the aged in the metropolitan region of Joao Pessoa, Paraiba, Brazil. Method: This is a descriptive, exploratory and quantitative research that was carried out between November/2012 and January/2014 in 11 institutions, composed by a sample of 26 caregivers. Two semi-structured questionnaires were used for data collection; Word Excel 2007 was used for selection and categorization of the data and SPSS was used for descriptive analysis. Results: The age range of the caregivers was between 25 and 82 years old. 88.5% are female; 38.5% are married; 19.23% of them reported receiving specific education to become caregivers and most of them (69.23%) did not acquire any sort of qualification. Conclusion: It is concluded that the hiring and qualification of caregivers is necessary for the direct work with the institutionalized elderly, which will greatly influence the assistance to be provided in these institutions, resulting in improving the health of all older people living there.
The effect of pictorial mode on children’s learning of new L1 lexical items

This research is aimed at investiagting the influence of using pictorial mode towards children’s learning of L1 new lexical items. This study is based on an experimental design. To reach the goal, 20 children as the sample were randomly selected from nurseries in Shiraz, Iran. The participants were 3 years old children divided in two groups of experimental and control. To estimate the impact of pictorial mode on children’s learning of L1 new lexical items, the same lexical items (the name of 3 animals) were provided to each group with different media; flashcard used in the experimental group, and in the control group just used some explanations about the characteristics of the animals. To collect the data, the researchers recorded children’s voice and then transcribed and scored their answers. The data were then analyzed using independent-samples t-test. The result shows that inasmuch as those in the experimental group surpassed those in the control group, it came to light that the use of pictorial mode greatly influenced children’s learning of new L1 lexical items.
A Generalized Processor Sharing Approach to Flow Control in Integrated Services Networks: The SingleNode Case

The problem of allocating network resources to the users of an integrated services network is investigated in the context of rate-based flow control. The network is assumed to be a virtual circuit, connection-based packet network. We show that the use of Generalized Processor Sharing (GPS), when combined with Leaky Bucket admission control, allows the network to make a wide range of worst-case performance guarantees on throughput and delay. The scheme is flexible in that different users may be given widely different performance guarantees, and is efficient in that each of the servers is work conserving. We present a practical packet-by-packet service discipline, PGPS (first proposed by Deniers, Shenker, and Keshav [7] under the name of Weighted Fair Queueing), that closely approximates GPS. This allows us to relate results for GPS to the packet-by-packet scheme in a precise manner. In this paper, the performance of a single-server GPS system is analyzed exactly from the standpoint of worst-case packet delay and burstiness when the sources are constrained by leaky buckets. The worst-case session backlogs are also determined. In the sequel to this paper, these results are extended to arbitrary topology networks with multiple nodes.
The interplay between geometry and function in the comprehension of''over

Three experiments are reported which examined the role of geometry and functional relations in the comprehension of the spatial prepositions over, under, above, and below. The tasks used consisted of rating how appropriate sentences (containing one of these prepositions) were to describe a series of pictures. For example, the pictures comprised a person holding an object with the function of protection from falling objects (e.g., an umbrella). Each picture was depicted with the object shown as fulfilling its function or not at different geometric positions. The results of Experiment 1 show a significant effect of functional relations on the ratings given. However, while over/under were very sensitive to functional relations, above/below were more influenced by geometric relations. The second experiment replicates these effects with objects depicting noncanonical functions (e.g., a suitcase sheltering someone from rain). Experiment 3 manipulated frame of reference and found evidence for conflict of frames of reference effects on the rating of above/below, but not in the same way for over/under. Conversely the ratings of over/under were found to be affected by functionality while those for above/below were not. These results indicate for the first time that spatial prepositions are differentially influenced by geometric and functional relations.
Résistance aux antibiotiques des entérobactéries au niveau du CHU de Sidi Bel Abbes (Algérie)

L'etude de 140 souches d'enterobacteries, isolees de differents services de l'hopital de Sidi Bel Abbes entre octobre 2009 et mai 2010, montre qu'Escherichia coli occupe la premiere place (37.1%) suivie de Klebsiella pneumoniae (21.4%), de Proteus spp. (19.3%) et d'Enterobacter cloacae (18.6%). Les resultats de l'antibiogramme pour 27 antibiotiques (18 β-lactamines, 4 aminosides, 3 quinolones, colistine et trimethoprime/sulfamethoxasole) par la methode de diffusion des disques en milieu gelose, selon les normes du CA-SFM, ont revele l'emergence des souches resistantes aux β-lactamines et a la majorite des autres classes d'antibiotiques sauf pour l'amikacine et l'imipeneme (3.6% et 4.3% respectivement). L'analyse des phenotypes de resistance aux β-lactamines est en faveur d'une dominance des souches productrices de β-lactamases a spectre etendu (BLSE) (37.1%), pour lesquelles plusieurs profils plasmidiques ont ete detectes dont un plasmide commun de poids moleculaire superieur a 55 kb.
A Novel Method for Inducing Therapeutic Hypothermia in a Swine Model of Blast-Induced Traumatic Brain Injury with Associated Hemorrhagic Shock

Abstract : The purpose of this study was to determine the effect of rapidly induced hypothermia on neurological outcomes following fluid percussion injury in swine. A second objective was to test the safety and efficacy of inducing hypothermia through augmented heat extraction from the lungs using heliox and perfluorocarbon mist ventilation. The hypothermia device was built and bench tested. Brain temperatures in all hypothermic animals reached target (32-33 C) within 60 minutes. We standardized the anatomical location and fluid force necessary to create consistent severe brain injury in pigs. Seven of the eight hypothermic and four of the eight normothermic animals survived to the end of the five-day study. Hypothermia effectively prevented the gradual rise in intracranial pressure. Neurological and behavioral scores were better in the surviving normothermic animals on day #3; however these differences disappeared by day #5. The results of serum biomarkers for brain injury and histopathological scores are being processed. The study was extended by six months due to the additional safety and feasibility requirements placed by Mayo IACUC and the inclusion of serum biomarkers into the protocol. If additional funding becomes available, the investigators will add a third arm to the study consisting of blast injury plus hemorrhagic shock.
Relationship between Death Anxiety and Mental Health Status among Nurses in Hospitals Affiliated to Babol University of Medical Sciences

BACKGROUND AND OBJECTIVE: Nurses are frequently faced with death and dying patients due to the nature of their job. Death anxiety in these people may be associated with depression, generalized anxiety and suicidal thoughts, which may impair their performance. This study aims to assess the relationship between death anxiety and mental health status among nurses. METHODS: This analytical study was carried out through evaluation the intensive care unit, emergency and operating room nurses in hospitals affiliated to Babol University of Medical Sciences using Templer's Death Anxiety Scale (DAS) and General Health Questionnaire (GHQ-28). DAS score ranged from 0 to 15; higher score indicated greater death anxiety. GHQ evaluated physical health, anxiety, social activity and depression. Respondents who got higher scores had more psychological problems. FINDINGS: Of 142 nurses who participated in this study, 88 nurses (68.7%) had high death anxiety and 40 nurses (31.3%) had low death anxiety. There were no significant relationship between death anxiety and variables of age, gender, marital status, place of activity and education level. There was a significant inverse relationship between death anxiety and subscales of GHQ including anxiety (p=0.008) and lack of social activity (43 nurses [31.6%] with low death anxiety vs. 93 nurses [68.4%] with high death anxiety) (p=0.046). CONCLUSION: The results of this study demonstrated that death anxiety is highly prevalent among nurses. Therefore, educational intervention programs are necessary to reduce death anxiety and its complications.
