Technological practice in early childhood as a dispositional milieu

This study investigated the learning of a group of four-year-olds as they worked in the construction area of a sessional early childhood setting. The researcher participated and observed as the children constructed with cardboard, rolled painted marbles around in a box to make Jackson Pollock style paintings, added collage and paint to pictures and constructions, and screen-printed cut-out figures and shapes of various kinds. These were described as technological practices, and five of them were compared as contexts for learning dispositions. Although the literature had provided discussion and definition of dispositions in early childhood, the connection between the psychological notion of disposition and an historically or socioculturally framed dispositional milieu had not been researched. The study investigated empirical evidence for a transactional model of the interface between learning disposition and dispositional milieu, and learning dispositions were located in discourse, narrative and technological practice. The affordance of the technology and the tools played an important part in the transaction between individual and environment, in particular the technology's transparency, challenge, and accessibility. The five technological practices were analysed as complex sociocultural worlds in which multiple discourses jostled for privileged positions, children made decisions about whether discourse membership was for display or for exploration, they tackled difficulty with enthusiasm or avoided it in imaginative ways, and they engaged with others from a range of positions of power and responsibility. These sequences of events were described as learning narratives: historically and socioculturally co­ constructed event structures about goals, challenge, and agency. A learning narrative was defined, identified, and investigated. Learning dispositions have been defined but not specified for early childhood. This study suggests that dispositions can be interpreted as parts of a learning narrative, and for this study key dispositional domains were identified as privileged discourses, preferred responses to difficulty, and favoured patterns of responsibility. Four learning dispositions emerged from these domains: courage, mindfulness, perseverance, and responsibility. These learning dispositions find a parallel in the strands of the early childhood curriculum document for Aotearoa New Zealand, Te Whciriki. The researcher followed up the observations by interviewing the children for their viewpoint on preferred responses to difficulty using an interview that reflected their experiences back to them as a picture book. Although much of the learning appeared to be attached to the context, and the privileged meaning and intent for that context was a key element, the transactional nature of the learning revealed individual learning dispositions and narratives that were developing in the early years and that may be robust and enduring.
Potential estimates for a class of fully nonlinear elliptic equations

We study the pointwise properties of k-subharmonic functions, that is, the viscosity subsolutions to the fully nonlinear elliptic equations F k[u] = 0, where Fk[u] is the elementary symmetric function of order k, 1 ≤ k ≤ n, of the eigenvalues of [ D2u ] , F1[u] = 1u, Fn[u] = detD2u. Thus1-subharmonic functions are subharmonic in the classical sense; n-subharmonic functions are convex. We use a special capacity to investigate the typical questions of potential theory: local behaviour, removability of singularities, and polar, negligible, and thin sets, and we obtain estimates for the capacity in terms of the Hausdorff measure. We also prove the Wiener test for the regularity of a boundary point for the Dirichlet problem for the fully nonlinear equation Fk[u] = 0. The crucial tool in the proofs of these results is the Radon measure Fk[u] introduced recently by N. Trudinger and X. -J. Wang for any k-subharmonic u. We use ideas from the potential theories both for the complex Monge-Amp ` re and for the p-Laplace equations.
Intraneuronal APP, Not Free Aβ Peptides in 3xTg-AD Mice: Implications for Tau versus Aβ-Mediated Alzheimer Neurodegeneration

Alzheimer's disease (AD) is characterized by the accumulation of intraneuronal tau and extracellular amyloid-β (Aβ) peptide. A triple transgenic (Tg) mouse (3xTg-AD) was reported to develop Aβ plaques and tau inclusions as well as remarkable accumulations of intracellular Aβ that were suggested to be the initiators of AD pathogenesis. However, it was unclear whether the anti-Aβ antibodies were able to distinguish Aβ peptide from the same Aβ epitopes within the amyloid precursor protein (APP). To further elucidate the identity of the immunoreactive intraneuronal material in 3xTg-AD mice, we conducted immunohistochemical, biochemical, and ultrastructural studies using a well characterized panel of antibodies that distinguish Aβ within APP from cleaved Aβ peptides. We found that the intraneuronal material shared epitopes with full-length APP but not free Aβ. To demonstrate unequivocally that this intraneuronal material was not free Aβ peptide, we generated 3xTg-AD mice deficient for β-secretase (BACE), the protease required for Aβ generation from APP. In the absence of Aβ production, robust intraneuronal APP immunostaining was detected in the 3xTg-AD/BACE−/− mice. Finally, we found that the formation of tau lesions was not different between 3xTg-AD versus 3xTg-AD/BACE−/− mice, thereby demonstrating that tau pathology forms independently from Aβ peptide generation in this mouse model. Although we cannot corroborate the presence of intraneuronal Aβ peptide in 3xTg-AD mice, our findings warrant further study as to the role of aberrant APP accumulation in this unique model of AD.
THE RELATIONSHIP BETWEEN THE SELECTED PERCENTAGES OF ONE REPETITION MAXIMUM AND THE NUMBER OF REPETITIONS IN TRAINED AND UNTRAINED MALES UDC

The purpose of this study was to determine the relationship between the maximum number of repetitions and selected percentages of one repetition maximum which could be performed by trained and untrained males, especially using free weights. Nine trained (T) and 9 untrained (UT) males participated in this study. The subjects performed one set to failure at 75, 85, and 95% of 1RM in the back squat, bench press, and arm curl, which were randomized, balanced, and matched. Data were analyzed using two-way analysis of variance. There were significant differences (p < 0.05) between T and UT at 85 and 95% of 1RM in the arm curl. At 75 and 85% of 1RM, T and UT performed more repetitions (p < 0.05) during the back squat than the bench press or arm curl. Both groups performed significantly (p < 0.05) more repetitions during 75% of 1RM than 85 and 95% of 1RM (75 > 85 > 95%). The rating of perceived exertion (RPE) was greater (p < 0.05) for high intensity than moderate intensity. In conclusion, the number of repetitions is dependent on the amount of muscle mass and exercise intensity, while the training status of the subjects has a minimal impact. When percentage of 1RM increases, the RPE increases as well.
Processus de collaboration interprofessionnelle en santé et services sociaux : proposition d'une grille d'observation des rencontres d'équipe interdisciplinaires

Nowadays, interprofessional collaboration (IPC) is considered an effective, efficient and a satisfactory way to provide health and social care. However, clinical settings are not currently well equipped to be able to evaluate IPC practices. In view of this problem, this doctoral project aims to help healthcare managers and practitioners evaluate the quality of IPC practices. The specific objectives are to: 1) propose a framework to illustrate how the interactional factors of IPC should or can be operationalized in clinical settings to promote good IPC practices; 2) describe the way in which the interactional factors come into play during an interdisciplinary team meeting and identify their observable indicators; 3) develop an observation-based instrument to evaluate IPC interactional factors occurring during interdisciplinary team meetings and examine the initial validation and reliability testing of this tool in a rehabilitation setting. To attain the first objective, a qualitative methodology was used involving a consultation of experts (n=20) via consensus group sessions and a survey. The second objective was attained following one consensus group session involving scientific and clinical experts (n=6) while the third objective was attained following a standardized procedure of tool development. Content validity was ensured by the participation of construct experts (n=6) in the generation of items. The inter-rater reliability of the tool was then examined in a rehabilitation setting by analyzing the agreement between two observers using Cohen's kappa (kappa ranged from .17 to .79). To do so, 30 interdisciplinary team meetings, were videotaped in two rehabilitation centers in Quebec (Canada). The results of these studies allowed developing a framework of IPC interactional factors illustrating five types of collaborative practices and allowed defining what happens during interdisciplinary team meetings in terms of IPC. Finally, an observation-based tool consisting of 20 items and a three-point scale with an acceptable reliability was developed. In conclusion, this thesis contributes knowledge about IPC practices by proposing an innovative conceptualization of IPC interactional factors while offering healthcare managers and practitioners a unique tool for assessing the quality of these factors through the observation of group behaviours during interdisciplinary team meetings.
Sexual Health Services for Homeless Youth: A Qualitative Analysis of their Experiences

Abstract The sexual health problems experienced by homeless youth bring into question their use of available sexual health services. Using a qualitative typological analysis, this study aims to identify sexual health services utilization profiles for homeless youth, and to understand the role of the homeless experience on the utilization of sexual health services. Individual interviews were conducted with 33 homeless youth (17 men, 16 women) between 18 and 25 years of age. Typological analysis identified four profiles: (1) a targeted use of sexual health services to determine one’s serological status following a relational change during the homeless experience; (2) a limited use of sexual health services to manage sexual emergencies that arise during the homeless experience; (3) a regular use of sexual health services to avoid the risks associated with the homeless experience; (4) a frequent use of sexual health services to obtain support when engaging in prostitution during the homeless experience. This study shows that the precarious and unstable conditions within the homeless experience incite youth to utilize sexual health services in different ways. These findings point to the importance of rethinking sexual health services to better adapt them to the different utilization profiles of homeless youth.
Unthresholded adaptive revocation technique in mobile ad hoc networks

Removing malicious nodes from any network is vital to its correct operation and enhances largely its security. This can be typically achieved by revoking or deactivating their credentials whenever a threshold of votes against them is reached. The problem of threshold based revocation schemes is that any colluding set of malicious nodes surpassing the threshold can revoke nodes in the networks at will. Lowering the threshold value, would make coalition attacks against the revocation protocol easier. Whereas increasing the threshold value would make the revocation of malicious nodes difficult. In this paper, we propose a new revocation scheme for mobile ad hoc networks which deals with the revocation problem adaptively, so that it allows the revocation of smaller sets of colluding malicious nodes easier, meanwhile it controls the number of erroneously revoked nodes caused by big sets of colluding attackers.
Magnetic Resonance Navigation of a Bead Inside a Three-Bifurcation PMMA Phantom Using an Imaging Gradient Coil Insert

This paper reports the successful navigation of a 1-mm Chrome-Steel bead along three consecutive polymethyl methacrylate channels inside the bore of a 1.5-T magnetic resonance imaging (MRI) scanner. The bead traveled at a mean velocity of 14 cm·s -1. This was accomplished using an imaging gradient coil (IGC) insert located inside the MRI tube. While targeting one side of a bifurcation has been previously demonstrated using unidirectional gradient coils, this is the first time that magnetic resonance navigation (MRN) of a bead along consecutive channels is reported. Experimental results confirm that a clinical regular MRI can be used to propel a 1-mm device. In addition, when used at maximum power, IGC temperature rise becomes a serious issue that can ultimately damage the insert and limit the overall performance. Consequently, this paper aims to give some insight into coil temperature management for IGC-assisted procedures. A 33-min thermal stress test was carried out using 100% of the IGC power. Steady-state oscillation can be reached by interleaving propulsion periods with cooling periods, thus enabling longer propulsion procedures. Experimental data showed that the cooling time can be used for imaging purposes with no performance loss, thus enabling MRN-assisted procedures with multiplexed particle distribution assessment.
Depth Map Coding Based on Synthesized View Distortion Function

This paper presents an efficient depth map coding method based on a newly defined rendering view distortion function. As compared to the conventional depth map coding in which distortion is measured by only investigating the coding error in depth map, the proposed scheme focuses on virtually synthesized view quality by involving co-located color information. In detail, the proposed distortion function estimates rendered view quality, where area-based scheme is provided in order to mimic the warping/view-rendering process accurately. Moreover, the coding performance of the proposed distortion metric is even improved by involving the additional SKIP mode derived by co-located color coding information. The simulation results show the proposed scheme could achieve approximately 30% bit-rate saving for depth data, and about 10% bit-rate saving for overall multi-view data.
A Luminous Recurrent Supersoft X-Ray Source in NGC 300

We report the results of XMM-Newton observations for an especially luminous supersoft X-ray source (SSS) with a bolometric luminosity of 1039 ergs s-1 in the spiral galaxy NGC 300. The source was detected as an SSS in 1992 and disappeared in subsequent X-ray observations. The source was active again during recent XMM-Newton observations. It appeared to be very soft (kT ~ 60 eV) and very luminous (~1038-1039 ergs s-1). The two XMM-Newton observations also reveal that the source went from a "high" state to a "low" state in 6 days. We also found a 5.4 hr periodicity during the low state. We consider white dwarf, black hole, and neutron star models in order to explain the nature of the source.
Changes in Gene Expression Predicting Local Control in Cervical Cancer: Results from Radiation Therapy Oncology Group 0128

Purpose: To evaluate the potential of gene expression signatures to predict response to treatment in locally advanced cervical cancer treated with definitive chemotherapy and radiation. Experimental Design: Tissue biopsies were collected from patients participating in Radiation Therapy Oncology Group (RTOG) 0128, a phase II trial evaluating the benefit of celecoxib in addition to cisplatin chemotherapy and radiation for locally advanced cervical cancer. Gene expression profiling was done and signatures of pretreatment, mid-treatment (before the first implant), and “changed” gene expression patterns between pre- and mid-treatment samples were determined. The ability of the gene signatures to predict local control versus local failure was evaluated. Two-group t test was done to identify the initial gene set separating these end points. Supervised classification methods were used to enrich the gene sets. The results were further validated by leave-one-out and 2-fold cross-validation. Results: Twenty-two patients had suitable material from pretreatment samples for analysis, and 13 paired pre- and mid-treatment samples were obtained. The changed gene expression signatures between the pre- and mid-treatment biopsies predicted response to treatment, separating patients with local failures from those who achieved local control with a seven-gene signature. The in-sample prediction rate, leave-one-out prediction rate, and 2-fold prediction rate are 100% for this seven-gene signature. This signature was enriched for cell cycle genes. Conclusions: Changed gene expression signatures during therapy in cervical cancer can predict outcome as measured by local control. After further validation, such findings could be applied to direct additional therapy for cervical cancer patients treated with chemotherapy and radiation.
Advanced Biometric Identification on Face, Gender and Age Recognition

The face recognition system attains good accuracy in personal identification when they are provided with a large set of training sets. In this paper, we proposed Advanced Biometric Identification on Face, Gender and Age Recognition (ABIFGAR)algorithm for face recognition that yields good results when only small training set is available and it works even with a raining set as small as one image per person. The process is divided into three phases: Pre-processing, Feature Extraction and Classification. The geometric features from a facial image are obtained based on the symmetry of human faces and the variation of gray levels, the positions of eyes, nose and mouth are located by applying the Canny edge operator. The gender and age are classified based on shape and texture information using Posteriori Class Probability and Artificial Neural Network respectively. It is observed that the face recognition is 100%, the gender and age classification is around 98% and 94% respectively.
ApJ The Survey of Nearby Nuclei with STIS ( SUNNS ) : Emission-Line Nuclei at Hubble Space Telescope Resolution 1

We present results from a program of optical spectroscopy for 23 nearby galaxies with emission-line nuclei. This investigation takes advantage of the spatial resolution of the Hubble Space Telescope to study the structure and energetics of the central ∼ 10− 20 pc, and the resulting data have value for quantifying central black hole masses, star formation histories, and nebular properties. This paper provides a description of the experimental design, and new findings from the study of emission lines. The sample targets span a range of nebular spectroscopic class, from H II to Seyfert nuclei. This data set and the resulting measurements are unique in terms of the sample size, the range of nebular class, and the investigation of physical scales extending down to parsecs. The line ratios indicative of nebular ionization show only modest variations over order-of-magnitude differences in radius, and demonstrate in a systematic way that geometrical dilution of the radiation field from a central source cannot be assumed as a primary driver of ionization structure. Comparisons between largeand small-aperture measurements for the H II/LINER transition objects provide a new test that challenges Based on observations with the NASA/ESA Hubble Space Telescope obtained at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS5-26555.

The Moxie JVM Experience

By January 1998, only two years after the launch of the first Java virtual machine, almost all JVMs in use today had been architected. In the nine years since, technology has advanced enormously, with respect to the underlying hardware, language implementation, and in the application domain. Although JVM technology has moved forward in leaps and bounds, basic design decisions made in the 90’s has anchored JVM implementation. The Moxie project set out to explore the question: ‘How would we design a JVM from scratch knowing what we know today? ’ Amid the mass of design questions we faced, the tension between performance and flexibility was pervasive, persistent and problematic. In this experience paper we describe the Moxie project and its lessons, a process which began with consulting experts from industry and academia, and ended with a fully working prototype.
Postintegrative Gene Silencing within the Sleeping Beauty Transposition System

ABSTRACT The Sleeping Beauty (SB) transposon represents an important vehicle for in vivo gene delivery because it can efficiently and stably integrate into mammalian genomes. In this report, we examined transposon expression in human cells using a novel nonselective fluorescence-activated cell sorter-based method and discovered that SB integrates ∼20 times more frequently than previously reported within systems that were dependent on transgene expression and likely subject to postintegrative gene silencing. Over time, phenotypic analysis of clonal integrants demonstrated that SB undergoes additional postintegrative gene silencing, which varied based on the promoter used for transgene expression. Molecular and biochemical studies suggested that transposon silencing was influenced by DNA methylation and histone deacetylation because both 5-aza-2′-deoxycytidine and trichostatin A partially rescued transgene silencing in clonal cell lines. Collectively, these data reveal the existence of a multicomponent postintegrative gene silencing network that efficiently targets invading transposon sequences for transcriptional silencing in mammalian cells.
Effect of Variations in Measurement Process for Software Development Efforts

Researchers have proposed that the reliability of software prediction models can be assessed by the following most widely used evaluation criterion, i.e., Difference Measure and Ratio Measure. Ratio measure is more suitable for the assessment of the accuracy in software cost estimation. Results in this research demonstrated that applying proposed method to the software effort estimation is by far the most feasible approach for addressing the problem of apprehension and ambiguity existing in software effort drivers. Small adjustments to the COCOMO cost drivers bring significant improvements to the quality criteria applied to the proposed approach.
