Gait Identification using Smartphone Handheld Placement with Linear Interpolation Factor, Single Magnitude and One-vs-One Classifier Mapping

Gait signal of a person can be easily obtained using a smartphone sensor. To get the source of the signal, the smartphone need to be placed in the pocket, pouch or attached to other parts of the body. In the real world application, it is hard to place the device on the mentioned position. The easiest way is to put it on hand. In another issue, the single magnitude is known in the use of multiple orientations. However, this method may discard useful features for machine learning classification. Another problem is that the signal captured using a smartphone is not in a fix sampling rate and in the small distance, hence interpolation needs to be applied so that the sampling can be in a fix sequence with more fix point data. However, too much application of interpolation may result in low prediction rate. Finally, a multiclass dataset may contain overlapped class boundary which produces low accuracy on a single classifier mapping. In this paper, hand based smartphone placement position is implemented and evaluated. Single magnitude application is also evaluated in representing multiple positions of a person into one signal. Besides that, the linear interpolation factor is introduced in sampling the signal. Lastly, OvO classification model is implemented in binarizing the multiclass gait dataset. From the experiment, it shows that using the mentioned method do produce satisfactory result hence opening a new gateway in a better gait identification/recognition system.
THE EXTENT OF MUlTIDISCIPlINARY AUTHORSHIP OF ARTIClES ON SCIENTOMETRICS AND BIBlIOMETRICS IN BRAZIl

Las publicaciones en cientometria y bibliometria con autores brasileros crecieron exponencialmente en el periodo 1990-2006, alcanzando 13 veces en la base de datos del Web of Science, y 19,5 veces en la del Google Scholar. Este incremento es marcadamente mayor que el de la produccion cientifica total en igual periodo (5,6 veces en el Web of Science). Algunas caracteristicas destacables en ese aumento son: 1) El numero total de articulos en ese periodo fue de 197; de ellos, 78% fueron publicados en 57 revistas brasileras y 22% en 13 revistas internacionales. 2) Los articulos nacionales e internacionales promediaron 4,3 y 5,9 citas/articulo, respectivamente; y dos resaltaron entre ellas, la revista nacional Ciencia da Informacao (44 articulos con promedio de 6,7 citas/articulo) y la internacional Scientometrics (32 articulos, con promedio de 6,2 citas/articulo). 3) En los articulos se aprecia una participacion impresionante de autores de areas diferentes a las ciencias de la informacion; solo un cuarto de ellos esta ligado a ese campo, distribuyendose el resto en las areas de humanidades/administracion, biologia/biomedicina, salud y ciencias exactas. La ocurrencia de autores a este nivel de multidisciplinaridad no es comun en ciencias; no obstante, los posibles beneficios de tal patron no estan claros a la vista de la intercomunicacion fragmentada entre autores, como se aprecia a traves de las citas. Se discute las ventajas de cambiar esta tendencia y de usar otras bases de datos cientometricas y bibliometricas, tales como SciELO, para evitar el uso casi exclusivo de la del Web of Science
First record of Aphelinus paramali Zehavi and Rosen 1989 (Hymenoptera, Aphelinidae), parasitoid of Aphis pomi de Geer (Hemiptera, Aphididae) in Iran, and its phylogenetic position based on sequence data of ITS2 and COI genes

The occurrence of Aphelinus paramali (Zehavi & Rosen) (Hym., Aphelinidae) was evidenced from North east Iran, in association with Aphis pomi (de Geer). This species is reported from Iran for the first time, and A. pomi is introduced as a new host for this parasitoid. Detailed morphological characters were studied with scanning electron microscopy (SEM) photographs. Also, sequences of ribosomal internal transcribed spacer 2 (ITS2) and cytochrome oxidase subunit I (COI) genes were used for determining species boundaries and comparing with other Aphelinus species. Different results were obtained in phylogenetic analysis of these two regions. Analysis of COI gene supported the closer relationship of this species with Aphelinus abdominalis. This is the first data about comprehensive characterization of a parasitic wasp using morphological characters, SEM and two‐locus information from Iran.
A Multi-Level Research on the Antecedents and Consequences of Group Task Satisfaction

In this study, in order to examine antecedents and consequences of group task satisfaction, We collected 204 questionnaires with 35 hotel groups from 4 hotels located in Guangzhou and Shenzhen and used HLM to test the relationship between group task satisfaction and other variables in group level and individual level. The research findings show that employee individual job satisfaction mediates the effect of group task satisfaction on employee turnover intention and job performance; group task satisfaction mediates the positive effect of group cohesion and group job characteristics on individual job performance; group cohesion moderates the effect of individual job satisfaction on turnover intention and job performance.
A Case Study Approach to Exploring the Relationship between Human Resources Management and Firm Performance

Research in the field of Strategic Human Resource Management (SRHM) has been especially wide and fruitful for the last two decades. Most of the work, however, has long been relied on cross-sectional studies and single respondent survey (SRSM) techniques. Models produced so far hence do not discuss the impact of people management practices over individuals and the relations among employee's outcomes and business unit or corporate results. The present paper presents a quantitative case study of a large financial services organization and explores the possible links among HR and individual and business unit levels of performance. Though being highly exploratory, the study raises a set of issues that might challenge some of the SHRM well-established statements such as the assumption of a direct, linear relationship between HR practices and business results, or the use of financial ratios as suitable indicators of the efficiency of people management practices.
Data Mining Application in Crime Analysis and Classification

The analysis of crime data helps to unravel hidden trends that will aid in better understanding of crime pattern and the nature of those who commits such crimes. It also enables appropriate strategies to be put in place to control such crimes. Literature revealed that data mining has been successfully applied in crime analysis and control. In this work the crime data used was collected from selected Nigerian prisons. Exploratory analysis was performed on the crime data for better insight into the dataset before application of data mining algorithms. The exploratory analyses revealed that majority of the offenders are within the ages of 18 to 34 years old. The mining algorithm was limited to two classification algorithms. C4.5 algorithm was used to classify the data into vulnerable and non vulnerable groups. To verify the reliability of the C4.5 algorithm, Naïve Bayes algorithm was also used to classify the dataset. The result showed that C4.5 classified the data better with higher accuracy of 97% against 93% from Naïve Bayes. The rule generated by the C4.5 classifier revealed that those without educational qualification and not gainfully employed are the vulnerable groups. The authors are of the opinion that education is the way out of crime in Nigeria since most of the offenders either have low educational qualification or none.
Intrapartum Transcutaneous Electrical Nerve Stimulation for Pain Relief and Outcome of Labour

Methods: This study was conducted over a 5-month period by purposive sampling of all the women who had requested TENS for pain relief during the early phase of labour and in the absence of significant complications or contraindications. Maternal demographics, pain scores as assessed by a validated pain assessment form, and labour outcomes were analysed according to the types of pain relief method used in the form of: TENS with or without entonox (TENS group); TENS and pethidine injection (pethidine group); and TENS with epidural analgesia (epidural group). Results: In the final study, 265 women (18% of labouring women within the study period) completed the assessment forms. TENS alone was sufficient for pain relief in 38% of these women, and 87% achieved spontaneous delivery compared with the other groups altogether (p = 0.004; adjusted odds ratio = 3.21; 95% confidence interval, 1.44-7.15). The duration of first stage (p = 0.046) and second stage (p < 0.001) were the shortest in the TENS group. Conclusion: The result of this survey showed that TENS alone with or without the addition of entonox was sufficient for pain relief in 38% of the women. Furthermore, the use of TENS was associated with the shortest first and second stages of labour, and highest rate of spontaneous delivery. The role and merits of TENS for pain relief in uncomplicated labour should be explored further. Hong Kong J Gynaecol Obstet Midwifery 2011; 11:54-8
A MODIFIED EFFICIENT RANDOMIZED RESPONSE MODEL

In this paper, the problem of estimating the population total of a sensitive quantitative variable has been considered. Odumade and Singh (2009) have given a RR model to estimate the population total of sensitive quantitative variable. We have given a modified RR model. It is noticed that the RR model envisaged by Odumade and Singh (2009) suffers with a difficulty that the optimum value of the constant involved in their RR model depends on the value of unknown parameter of the study variable, which lacks the utility of their RR model. To overcome such a difficulty Odumade and Singh (2009) have also suggested another estimator of the population total which depends on two RR models based on two independent random samples s1 and s2 from the population  using the sampling design   p s1 and   p s2 respectively; and also on a relation between the two constants involved in the two RR models. We should add here that drawing the two independent samples from a population constructing two RR models resultantly obtaining an estimator for a population total Y increase the cost of the survey. Keeping this in view we have suggested a RR model and developed an estimator for population total based on a single sample. The proposed RR model is free from the difficulty involved in Odumade and Singh (2009) model. We have shown theoretically that the proposed randomized response model is more efficient than Bar-Lev et al (2004) and Odumade and Singh (2009) RR models. This fact has also been supported through numerical illustration.

How people learn to skip steps.

Novices often explicitly apply in a domain each necessary operator while solving a problem, whereas experts often skip steps, and as a result, the solution procedures they use are often organized differently from those of novices. Using an algebra analog, the authors examined this change in process. In 2 experiments, people learned the rules of the task and then solved many problems. Their solution procedures were monitored, and concurrent verbal protocols were taken. When participants started overtly skipping steps, they appeared to be performing them mentally but later started to use new transformations, thereby covertly skipping steps as well. An adaptive control of thought—rational model (J. R. Anderson, 1993) of problem-solver behavior within this task was developed and evaluated with respect to existing theories of skill acquisition. As people solve the same type of problem again and again, not only do they get faster at doing that type of problem, but very often the process they use to solve the problems changes as well, often resulting in skipped steps (Koedinger & Anderson, 1990). This reorganization and skipping of steps allow people to solve problems more quickly, efficiently, and easily. One might expect this change in process to result in performance discontinuities in a person's acquisition of a skill because the person is undergoing what may be a radical reorganization of how that skill is performed. However, Newell and Rosenbloom (1981) showed that a variety of skills are acquired at a steady rate, one that follows a power function (an equation of the form y = a + bxc, where a, b, and c are constants). In this article we examine the step-skipping phenomenon and its apparent relationship to the power law of learning. Step skipping is often thought of as a compositional process, in which a person who used to take two or more steps to do a task now takes only one. Intuitively then, if a person does a problem in fewer steps in completing a task, he or she should take less time in performing that task. Research by Charness and Campbell (1988) showed that compositional processes account for about 70% of the speedup associated with acquiring a new skill, with the rest of the speedup accounted for by becoming faster at the operations themselves. Work done by Frensch and Geary (1993; Frensch, 1991) also indicated the importance of compositional processes, as distinct from a general speedup in performance, in learning a task. It is evident from this research that composition is an important component to acquiring a skill.
Parental education and child health: evidence from China

This paper examines the effect of parental, household and community character-istics on the health of children in China. We find that birth order, death of elder siblings, use of prenatal care and alcohol consumption by the mother when pregnant have statistically significant effects on the health of children. Although parental education does not have a significant direct effect on child health, it does affect mothers' behavior during pregnancy and inflfluences the use of health inputs, indirectly impacting the health of children. The research findings have important implications for both family planning programs and broader social policies in China. Copyright 2006 East Asian Economic Association.
Estimating national wealth : methodology and results

This paper builds on the concept of wealth (or the asset base) as the foundation of generating well-being. National wealth takes on a much broader definition and is embodied in natural capital, social capital, and produced assets. The paper provides details on the methodology and assumptions used in estimating these magnitudes. The results show that human resources play a predominant role, thus lending support to investments in education and health. They also highlight the importance of agricultural cropland and pasture land, pointing to the need for sustainable land management practices. For countries rich in sub-soil assets the importance of investing, rather than consuming, returns from extraction of oil, minerals, coal, gas, and other exhaustible resources needs to be stressed.
Risk Analysis of the Space Shuttle : Pre-Challenger Bayesian Prediction of Failure NASA Space Systems Engineering & Risk Management Symposium

Dalal et al performed a statistical analysis of field and nozzle O-ring data collected prior to the ill-fated launch of the Challenger in January 1986. The purpose of their analysis was to show how statistical analysis could be used to provide information to decisionmakers prior to the launch, information that could have been expected to lead to a decision to abort the launch due to the low temperatures (~30 F.) present at the launch pad on the morning of the scheduled launch. Dalal et al. performed a frequentist analysis of the O-ring data, and found that a logistic regression model provided a relatively good fit to the past data. In the second portion of their paper, Dalal et al. propagated parameter uncertainties through the fitted logistic regression model in order to estimate the probability of shuttle failure due to O-ring failure at the estimated launch temperature of ~30 F. Because their analysis was frequentist in nature, probability distributions representing epistemic uncertainty in the input parameters were not available, and the authors had to resort to an approximate approach based on bootstrap confidence intervals. In this paper, we will re-evaluate the analyses of Dalal et al. from a Bayesian perspective. Markov chain Monte Carlo (MCMC) sampling will be used to sample from the joint posterior distribution of the model parameters, and to sample from the posterior predictive distributions at the estimated launch temperature, a temperature that had not been observed in prior launches of the space shuttle. Uncertainties, which are represented by probability distributions in the Bayesian approach, are propagated through the model to obtain a probability distribution for O-ring failure, and subsequently for shuttle failure as a result of O-ring failure. No approximations are required in the Bayesian approach and the resulting distributions can be input to a decision analysis to obtain expected utility for the decision to launch. When using a mathematical model, careful attention must be given to uncertainties in the model. Richard Feynman

Contrast Sensitivity and Night Driving in Older People: Quantifying the Relationship Between Visual Acuity, Contrast Sensitivity, and Hazard Detection Distance in a Night-Time Driving Simulator

Purpose (i) To assess how well contrast sensitivity (CS) predicts night-time hazard detection distance (a key component of night driving ability), in normally sighted older drivers, relative to a conventional measure of high contrast visual acuity (VA); (ii) To evaluate whether CS can be accurately quantified within a night driving simulator. Materials and Methods Participants were 15 (five female) ophthalmologically healthy adults, aged 55–81 years. CS was measured in a driving simulator using Landolt Cs, presented under static or dynamic driving conditions, and with or without glare. In the dynamic driving conditions, the participant was asked to simultaneously maintain a (virtual) speed of 60 km/h on a country road. In the with glare conditions, two calibrated LED arrays, moved by cable robots, simulated the trajectories and luminance characteristics of the (low beam) headlights of an approaching car. For comparison, CS was also measured clinically (with and without glare) using a Optovist I instrument (Vistec Inc., Olching, Germany). Visual acuity (VA) thresholds were also assessed at high and low contrast using the Freiburg Visual Acuity Test (FrACT) under photopic conditions. As a measure of driving performance, median hazard detection distance (MHDD) was computed, in meters, across three kinds of simulated obstacles of varying contrast. Results Contrast sensitivity and low contrast VA were both significantly associated with driving performance (both P < 0.01), whereas conventional high contrast acuity was not (P = 0.10). There was good correlation (P < 0.01) between CS measured in the driving simulator and a conventional clinical instrument (Optovist I). As expected, CS was shown to decrease in the presence of glare, in dynamic driving conditions, and as a function of age (all P < 0.01). Conclusion Contrast sensitivity and low contrast VA predict night-time hazard detection ability in a manner that conventional high contrast VA does not. Either may therefore provide a useful metric for assessing fitness to drive at night, particularly in older individuals. CS measurements can be made within a driving simulator, and the data are in good agreement with conventional clinical methods (Optovist I).
FOR BIOGENIC SULPHIDE REAGENT FOR COPPER RECOVERY IN COPPER AND GOLD HYDROMETALLURGICAL OPERATIONS

Sulphide is an effective reagent in the precipitation of base metals for both metal winning and environmental control. BioteQ Environmental Technologies Inc. has successfully demonstrated in industrial plants that biogenic sulphide reagent can be generated cost effectively and used to win metals such as copper, zinc and nickel from low-grade leach solutions and wastewater. Commercial plants in which sulphide reagent is used to produce high quality treated effluents for discharge directly to the environment are also in operation. Operations utilizing biogenic sulphide reagent for copper recovery from acid drainage and low grade leach solutions are discussed, including those at Bisbee, Arizona, commissioned in 2004 and at the Dexing mine in China, scheduled for commissioning in 2007. In addition, a new application of BioteQ’s technology for the recovery of copper from gold-cyanide solutions, and the regeneration of cyanide, utilizing biogenic sulphide in place of chemical sulphide reagents in the SART process is described.
Prediction of User Satisfaction in Naturalistic Human-Computer Interaction

User satisfaction is an important aspect of human-computer interaction (HCI) - if a user is not satisfed, he or she might not be willing to use such a system. Therefore, it is crucial to HCI applications to be able to recognise the user satisfaction level in order to react in an appropriate way. For such recognition tasks, data-driven methods have proven to deliver useful and robust results. But a data-driven user satisfaction model needs labelled and reliable data, which is not always easy in the case of user satisfaction, since it is not accessible directly. In the investigation presented here, the users are asked directly about their satisfaction level regarding their performance in a task during a close-to-real-life HCI. This results in a one-to-one mapping between a satisfaction level and the expressed vocal characteristics in the user's utterance. This data is then used to build a model to recognise satised and dissatised user states - as a first step towards a general model of the user's satisfaction state.
