Observations of Childrens' Responses to Different Types of Adult Authority Figures

The present study examined children’s responses to directives from teachers and student teachers in the classroom. According to previous interview data, children should demonstrate greater obedience to a teacher than to a student teacher due to her higher social position and greater knowledge. Seventeen second grade children were observed in their classroom as they interacted with the different authority figures. The authority figures’ directives and the children’s responses were categorized using coding systems developed for the study. Results show an interaction between gender and response to authority figure directives. Children, in general, were less compliant with the student teacher and this was more so for the boys. It was also found that student teachers use more requests as directives than teachers. Observations of children’s responses 3 Observations of Children’s Responses to Different Types of Adult Authority Figures A child can respond to different authority figures in many different ways. This research examined children’s responses to different authority figures depending on the social status and knowledge possessed by the authority figure. The observations were made within the context of the school. How a child responds to authority and obedience is one aspect of moral development and different theories regarding this development will be examined in the following paragraphs.
Three-dimensional ballistocardiography and seismocardiography in parabolic flight: Preliminary results from the esa b3d project

Ballistocardiography (BCG) is a technique that had a large interest in cardiology between the fifties and eighties. Typically BCG consisted in the recording of mechanical acceleration (Acc), caused by cardiac activity, on a subject lying on a table. As Acc was recorded only in the 2-dimensions (2D) of the horizontal plane, the antero-posterior (Z-axis) component was often neglected. From past experiments conducted in space [1,2] it was suggested that this component was comparable in magnitude to the other two and that Ballistocardiography should be recorded in threedimensions (3D). These observations and the recent modest regain of interest in the BCG technique were the starting point of the B3D project selected by ESA for the definition phase after the AO-2009. We recorded 3D Acc at various positions on the surface of the body (close to the centre of mass (CM), at the apex of the heart and on the sternum) of 8 healthy volunteers during free floating periods of parabolic flight (PF) manoeuvre (ESA 55th and DLR 19th PF campaigns conducted on-board the A300-zéroG airplane of NOVESPACE). Out of the many recordings collected, only a very limited number provided body Acc free from artefacts. Nevertheless, our results show that Seismocardiograms (SCG) and Ballistocardiograms (BCG) waves were qualitatively and quantitatively comparable in the frontal plane while larger differences were present along the antero-posterior component. Our limited number of artefact free episodes demonstrates the intrinsic difficulties of 3D recordings of SCG and BCG in PF and thus the need for a study in sustained microgravity. Moreover, our results confirm that the ventro-dorsal component of BCG is of similar amplitude as the other two which further demonstrates that the three components are essential to provide a physiological interpretation of BCG and SCG signals.
Survival of non-Hodgkin lymphoma patients with and without HIV infection in the era of combined antiretroviral therapy

Objective:To investigate the survival outcomes for non-Hodgkin lymphoma (NHL) in HIV-infected vs. uninfected patients from the same integrated healthcare system, and to identify prognostic factors for HIV-related NHL in the era of combined antiretroviral therapy. Design:A cohort study. Methods:Incident NHL diagnosed between 1996 and 2005 were identified from members of Kaiser Permanente California Health Plans. Two-year all-cause and lymphoma-specific mortality by HIV status were examined using multivariable Poisson regression. Among HIV-infected patients, prognostic factors of demographics, lymphoma, and HIV-related characteristics for the same outcomes were also examined. Results:A total of 259 HIV-infected and 8230 HIV-uninfected incident NHL patients were evaluated. Fifty-nine percent of HIV-infected patients died within 2 years after NHL diagnosis as compared with 30% of HIV-uninfected patients. HIV status was independently associated with a doubling of 2-year all-cause mortality (relative risk = 2.0, 95% confidence interval 1.7–2.3). This elevated mortality risk for HIV-infected patients was similar for all race groups, lymphoma stages, and histologic subtypes. HIV-infected patients with CD4 cell count below 200 cells/μl, prior AIDS-defining illness, or both were also at increased risk for lymphoma-specific mortality as compared with HIV-uninfected patients. Among HIV-infected NHL patients, significant prognostic factors for overall mortality included prior AIDS-defining illness and Burkitt's subtype. Conclusion:HIV-infected patients with NHL in the combined antiretroviral therapy era continue to endure substantially higher mortality compared with HIV-uninfected patients with NHL. Better management and therapeutic approaches to extend survival time for HIV-related NHL are needed.
Nonlinear Model predictive control of Dynamic Positioning of Deep-Sea ships with a Unified Model

In this paper, a six degrees-of-freedom uniﬁed model of ship is established based on one dynamic positioning (DP) vessel, in which sea environment models of wind, current and waves are included. Then, the controller of DP ship based on a kind of nonlinear model predictive control algorithm is designed. By choosing an appropriate predictive period, the DP ship can move to the desired position and heading quickly and accurately. Finally, the stability of the developed control system for dynamic positioning of ships is proved by theoretical and simulation studies.
Toxic effects of human and rodent variants of alpha‐synuclein in vivo

In Parkinson's disease, abnormal alpha‐synuclein (asyn) accumulation leads to the formation of soluble oligomeric species thought to be toxic to cells as well as intraneuronal inclusions. To date, the precise mechanisms leading to aggregation of asyn in the brain is not well‐understood. Previous studies in yeast, drosophila, and transgenic mice suggested that a non‐A beta component depleted version of human asyn [h‐asyn(D70‐83)] or human beta‐synuclein (h‐bsyn), naturally lacking this centrally located hydrophobic region, are less prone to form aggregates in vitro and are expected to be less toxic compared to h‐asyn in vivo, although not all experimental studies unequivocally support the latter view. To address this outstanding issue, we directly compared the neurotoxicity of human asyn against that of h‐asyn(D70‐83), h‐bsyn as well as rat asyn using an adeno‐associated viral vector to express these proteins in a dose‐response study where the vector load was varied over two orders of magnitude. By quantifying the neurodegeneration of rat substantia nigra dopamine neurons here we show that h‐asyn, h‐bsyn, and h‐asyn(D70‐83) display comparable neurotoxicity across the vector doses tested. On the other hand, rat asyn and GFP control vectors displayed a different profile, where no detectable neurodegeneration was seen except at the highest vector titer. Thus, the two main conclusions of our study are that (i) deletion of the central hydrophobic region in h‐asyn is not sufficient to alter its neurotoxic properties and (ii) expression of the widely used GFP control protein can cause measurable neurodegeneration at high titers.
Production, characterization, and evaluation of the stability of biodiesel obtained from greasy agroindustrial waste during storage

ABSTRACT Greasy agroindustrial waste from the process of cooking hog meat was used to produce biodiesel (fatty acid methyl esters and fatty acid ethyl esters) under a specific storage condition. The operating conditions necessary to achieve the optimal relationship between quality and productivity were assessed. Next, batches of methyl and ethyl biodiesels were produced, generating 2 L of each product to evaluate their stability during 150 days of storage. The following study indicates that, for methyl route, the molar ratio (1:5) and catalyst (0.5%) yielded the best result of 90.77% (w/v) and quality parameters within the international standards. The ethyl route also showed the highest yield (77.09% w/v) and better quality parameters with a molar ratio (1:5) and catalyst (0.5%). No significant differences were observed in the methyl biodiesel obtained from the batch process for up to 45 days, while the ethyl biodiesel degraded in 30 days of storage.
Using Cognitive Radio for Improving the Capacity of Wireless Mesh Networks

We propose the application of the overlay cognitive radio model to the communication of links within a wireless mesh networks. Based on the communication paradigm proposed by Jovicic and Viswanath, it is possible to have two concurrent transmissions in a given interference region. As as result, considerable network capacity gains are achieved. For the simple case of a network with a chain topology, the gains are as high as 33%.
Production of Glycolipid Biosurfactants, Mannosylerythritol Lipids, by a Smut Fungus, Ustilago scitaminea NBRC 32730

A smut fungus Ustilago scitaminea NBRC 32730 on sugar cane (Saccharum) was found to accumulate a large amount of glycolipids in the culture medium. As a result of structural characterization, the main glycolipid was identified as MEL-B, 4-O-β-(2′,3′-di-O-alka(e)noyl-6′-O-acetyl-D-mannopyranosyl)-erythritol. The MEL-B was sufficiently produced from a variety of sugars such as sucrose, glucose, fructose, and mannose. Olive oil and methyl oleate were also available as carbon sources to produce MEL-B. However, these residual oils made product recovery very complicated. Under optimal conditions, a maximum MEL yield of 12.8 g/l was achieved by feeding of sucrose.
2,3,4,6-Tetra-O-acetyl-β-d-galactopyranosyl 2-(2,4-dichloroanilino)-4,4-dimethyl-6-oxocyclohex-1-enecarbodithioate

The cyclohexene ring in the title compound, C29H33Cl2NO10S2, adopts an envelope conformation, with the C atom bearing the two methyl groups representing the flap. This atom deviates by 0.63 (1) Å from the plane through the other five ring atoms (r.m.s. deviation = 0.11 Å). The molecular conformation is stabilized by an intramolecular N—H⋯S hydrogen bond. The crystal studied was a non-merohedral twin, with a minor twin component of 29%.
Immediate Single-Stage Breast Reconstruction Using Implants and Human Acellular Dermal Tissue Matrix With Adjustment of the Lower Pole of the Breast to Reduce Unwanted Lift

Breast reconstruction using implants remains an aesthetic challenge toward achieving symmetry and natural appearance. Closing the areolar defect results in a vertically elevated breast mound. The use of human acellular dermal tissue matrix has been reported to provide coverage and durability over breast implants while allowing for improved shape of the reconstructed breast. This study reports the operative technique used in a series of breast reconstructions using saline implants and human acellular dermal tissue matrix in an immediate one-stage procedure. Complications and appearance were evaluated for all reconstructions. Indications for inframammary fold reconstruction and lower pole breast enhancement using chest skin advancement were discussed. Twenty-three patients were included in the study; 11 had unilateral reconstruction and 12 had bilateral reconstruction for 35 total reconstructions. All patients had immediate reconstruction following skin-sparing mastectomy. Nine patients had inframammary fold reconstruction and 11 patients had a lower chest advancement flap with fold reconstruction. The mean follow-up was 9.5 months with a range of 1 to 24 months. Complications occurred in 3 patients. Human acellular dermal tissue matrix can successfully be used in conjunction with breast implants to achieve an aesthetically pleasing breast reconstruction in one stage at the time of skin-sparing mastectomy. The use of a tissue expander and its associated risks and costs are eliminated. The complication rate is low. In addition, either inframammary fold reconstruction or lower chest advancement and fold reconstruction to augment lower pole skin coverage can improve symmetry with the opposite breast.
A sample of paediatric residents' loneliness-anxiety-depression-burnout and job satisfaction with probable affecting factors.

OBJECTIVE To assess levels of anxiety, depression, loneliness, burnout and job satisfaction among paediatric Residents, and how they influence each other. METHODS The cross-sectional study was conducted at Necmettin Erbakan University, Meram, and Konya Meram Education and Research Hospital, Turkey from January to June 2011, and comprised paediatric Residents and their counterparts from other departments who formed the control group. While maintaining confidentiality, a questionnaire was used to collect data that had elements of the University of California, Los Angeles, Loneliness Scale, Hospital Anxiety and Depression Scale, Maslach Burnout Inventory and Minnesota Job Satisfaction Questionnaire. SPSS version 13 was used for statistical analysis. RESULTS Overall there were 74 Residents in the study; 43 (58%) working with the paediatrics department, and 31 (42%) in the control group. Overall mean age was 27.60 ± 2.25 years. Residents who were not satisfied with the city they were living in, with their professional career and who would not choose the same career given a second chance were feeling more lonely and had higher loneliness scores (p < 0.05). In contrast, anxiety among female Residents who were unsatisfied with their professional career and working conditions was significantly high (p < 0.05). Positive correlation was detected between the burnout levels of Residents and their anxiety, depression and loneliness scores (r = 0.74; r = 0.65; r = 0.36). In terms of intrinsic, extrinsic and total job satisfaction, there was an obvious negative correlation (r = -0.57; r = -0.54; r = -0.61). CONCLUSION Working conditions and professional liability were the main factors affecting the Residents. Informed decision and career willingness may help them feel better.
Consistent Iterative Multiview Transfer Learning for Person Re-identification

Inconsistent data distributions among multiple views is one of the most crucial aspects of person re-identification. To solve the problem, this paper presents a novel strategy called consistent iterative multi-view transfer learning model. The proposed model captures seven groups of multiview visual words (MvVW) through an unsupervised cluster method (K-means) from human body. For each group of MvVW, a multi-view discriminative common subspace can be obtained by the fusion of transfer learning and discriminative analysis. In these common subspaces, the original samples can be reconstructed based on MvVW under the low-rank and sparse constraints. Then, we solve it via the inexact augmented Lagrange multiplier method. The proposed strategy is performed on three different challenging person re-identification databases (i.e., VIPeR, CUHK01 and PRID450S), which shows that our model outperforms several state-of-the-art models with improving of 6.36%, 7.7% and 4.0% respectively.
New methods for chicken embryo manipulations

The capacity to image a growing embryo while simultaneously studying the developmental function of specific molecules provides invaluable information on embryogenesis. However, until recently, this approach was accomplished with difficulty both because of the advanced technology needed and because an easy method of minimizing damage to the embryo was unavailable. Here, we present a novel way of adapting the well‐known EC culture of whole chick embryos to time‐lapse imaging and to functional molecular studies using blocking agents. The novelty of our method stems from the ability to apply blocking agents ex ovo as well as in ovo. We were able to study the function of a set of molecules by culturing developing embryos ex ovo in tissue culture media containing these molecules or by injecting them underneath the live embryo in ovo. The in ovo preparation is particularly valuable, because it extends the period of time during which the developmental function of the molecule can be studied and it provides an easy, reproducible method for screening a batch of molecules. These new techniques will prove very helpful in visualizing and understanding the role of specific molecules during embryonic morphogenesis, including blood vessel formation. Microsc. Res.

Estimating Evaporation: A Technique Adaptable to Remote Sensing

A procedure is presented for calculating 24-hour totals of evaporation from wet and drying soils. Its application requires a knowledge of the daily solar radiation and the maximum and minimum air temperatures (standard Weather Service measurements), moist surface albedo (readily estimated or obtainable from a one-time measurement), and maximum and minimum surface temperatures (obtainable from surface or airborne sensors). Tests of the technique on a bare field of Avondale loam at Phoenix, Arizona, have shown it to be independent of season.
Virtual reality and motor rehabilitation of the upper limb after stroke: a generation of progress?

AIM To review the rationale, criteria of application, potentialities and limits of the available procedures for upper limb rehabilitation in virtual reality setups. METHODS Classification of the available virtual reality setups and comparison among published studies, with focus on the criteria of motor impairment and recovery assessment, rehabilitation procedures, and efficacy. RESULTS AND CONCLUSION The studies completed to date support application of virtual reality methods in the treatment of the paretic upper limb after stroke, but the superiority of virtual reality methods in comparison with conventional procedures currently in use is still unproven. Larger samples, adequate controlled study design and follow-up, greater homogeneity in the selection criteria and parameters measuring severity of stroke, motor impairment and recovery are necessary.
Online action detection and forecast via Multitask deep Recurrent Neural Networks

Online human action detection and forecast on untrimmed 3D skeleton sequences is a novel task based on traditional action recognition and has not been fully studied. Its aim is to localize and recognize one action in a long sequence while doing forecasting task at the same time. In this paper, we propose an online detection algorithm featuring Multi-Task Recurrent Neural Network to solve this problem. First, a deep Long Short Term Memory (LSTM) network is designed for feature extraction and temporal dynamic modeling. Then we utilize a classification subnetwork to classify one action, and predict the status of it at the same time. To forecast the occurrence of actions and estimate the accurate time of occurrence, we incorporate a regression subnetwork to our model. Then we split the action classes to three stages and train the model by optimizing a joint classification regression objective function. Experimental results show that the proposed model achieves satisfactory results on online action detection and forecast.
MEASUREMENT OF COMPLEX PERMITTIVITY OF LIQUIDS USING WAVEGUIDE TECHNIQUES - ABSTRACT

Complex permittivity of a number of liquids and binary mixtures has been studied by measurement using the waveguide techniques at the X and Ku band. Particular pieces of WR90 and WR62 waveguides were designed for the measurement of liquid materials. The custom designed TRL calibration kits are applied for calibration of the waveguide system. The measured results of complex permittivity of liquid dielectrics, such as methanol, propyl alcohol, ethyl alcohol, chlorobenzene, dioxane, cyclohexane and binary mixtures, are presented. Particular pieces of open-ended waveguides for the X and Ku bands were also designed for holding liquids and the measured data using the open-ended waveguide technique were compared with those measured using the waveguide technique. Some of the measured results are also compared with calculated data using the Debye equation and published data measured by the Fourier transform spectroscopy.
Web-based collaborative framework and environment for designing and building robotic systems

Presents a preliminary research effort, on a Web-based collaborative design platform for robotic systems. The issues involved in the development process of (micro) robotic systems are first discussed. Then, a knowledge-server based Web distributed object modeling and evaluation framework (WebDOME) is proposed to enable designers to build concurrent integrated models using both local and distributed resources, and to collaborate by exchanging services based upon the CORBA standard communication protocol. To facilitate the rapid construction of integrated models for robotic system CAD, a prototype Web-based collaborative environment, WebRobot, is implemented under the WebDOME framework with concurrent integration of multiple cooperative knowledge sources and software. The system can provide platform-independent and distributed users access to WebDOME module servers throughout the network over the Internet/intranet and WWW. A case study is provided to demonstrate the functionality of the system and to illustrate how designers in different teams and organizations may participate and collaborate in the design process of robotic systems.
Targeting of «T» Lymphocytes against Human Hepatoma Cells by a Bispecific Monoclonal Antibody: Role of Different Lymphocyte Subsets

In an attempt to construct bispecific monoclonal antibodies (bimAbs) able to target cytotoxic T lymphocytes against human hepatoma cells, an HGPRT-deficient mutant of the Hepama-6 hybridoma, which produces an antihuman-hepatoma mAb, was directly fused with splenocytes from Balb/C mice immunized by a polyclonal cytotoxic T-cell line. Hybrid hybridomas were selected in HAT medium, and their supernatants were directly screened for the ability to induce IL-2-cultured cytotoxic T lymphocytes to kill hepatoma cells in a 51Cr-release assay. The selected hybrid hybridoma, termed DQ-33, secretes a bimAb, which reacts with a CD3-associated determinant. When resting peripheral-blood lymphocytes were used as effector cells, virtually no cytolytic activity could be induced by DQ-33, whereas phytohemagglutinin-activated lymphocytes that had been expanded in vitro in IL-2-containing medium could be efficiently targeted against hepatoma cells. Targeting by DQ-33 bimAb was analyzed on different subsets of IL-2-cultured lymphocytes. It was evident that CD+4–8+ TCRα/β+ and CD3+4–8-TCRγ/δ+ lymphocytes were efficiently induced by bimAb to lyse human hepatoma cells, whereas no induction of cytolysis could be observed when CD3 + 4+8-TCRα/β+ cells were used as effectors. DQ-33 bimAb was also able to induce lymphokine secretion (IL-2, GM-CSF and TNF-α) by all the different subsets of lymphocytes analyzed in the presence of target cells expressing the relevant antigen, independent of the expression of cytolytic activity.
