Teacher training in GIS: what is needed for long-term success?

Abstract This article explores teacher training in geographic information system (GIS) and hopes to uncover the necessary elements required for long-term and sustained use of GIS in the K-12 classroom. A variety of models have been proposed for successful GIS professional development including long-term teacher training lasting up to a year in length. Our study takes an additional step by following up with teachers over a full year after they have completed training to determine if they are continuing to teach with GIS and if so, how. We find there remains a disconnect between providing GIS teacher professional development and actually seeing long-term classroom implementation. We offer three recommendations for transformation in teacher practice: pre-service teacher geography and GIS intervention, continuous follow-up and coaching, and including GIS in Academic Standards.
Chapter I: First-Grade Reading Success Study: A Summary

The proper concern of professional education is to assure competent service to children, service which produces high achievement and eliminates unnecessary failure. Success in initial oiassroom instruction is more important than providing remedy after failure. This is particularly true in learning to read, since reading is an essential basis for later school achievement. After twenty-five years of clinical service.and research related to reading instruction, it seemed desirable to the language arts staff of Boston University to conduct a large-scale.study which employed practices indicated as desirable by research and clinical experience. A grant was obtained which made possible a cooperative study which involved more than 2,000 firstgrade children.
Genetic alterations in hepatocellular carcinoma: An update

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths worldwide. Although recent advances in therapeutic approaches for treating HCC have improved the prognoses of patients with HCC, this cancer is still associated with a poor survival rate mainly due to late diagnosis. Therefore, a diagnosis must be made sufficiently early to perform curative and effective treatments. There is a need for a deeper understanding of the molecular mechanisms underlying the initiation and progression of HCC because these mechanisms are critical for making early diagnoses and developing novel therapeutic strategies. Over the past decade, much progress has been made in elucidating the molecular mechanisms underlying hepatocarcinogenesis. In particular, recent advances in next-generation sequencing technologies have revealed numerous genetic alterations, including recurrently mutated genes and dysregulated signaling pathways in HCC. A better understanding of the genetic alterations in HCC could contribute to identifying potential driver mutations and discovering novel therapeutic targets in the future. In this article, we summarize the current advances in research on the genetic alterations, including genomic instability, single-nucleotide polymorphisms, somatic mutations and deregulated signaling pathways, implicated in the initiation and progression of HCC. We also attempt to elucidate some of the genetic mechanisms that contribute to making early diagnoses of and developing molecularly targeted therapies for HCC.
Molecular and proteomic insight into Notch1 characterization in hepatocellular carcinoma

Hepatocellular carcinoma (HCC) ranks fifth in frequency worldwide amongst all human cancers causing one million deaths annually. Despite many promising treatment options, long-term prognosis remains dismal for the majority of patients who develop recurrence or present with advanced disease. Notch signaling is an evolutionarily conserved pathway crucial for the development and homeostasis of many organs including liver. Herein we showed that aberrant Notch1 is linked to HCC development, tumor recurrence and invasion, which might be mediated, at least in part, through the Notch1-E-Cadherin pathway. Collectively, these findings suggest that targeting Notch1 has important therapeutic value in hepatocellular carcinoma. In this regard, comparative analysis of the secretome of HepG2 and HepG2 Notch1 depleted cells identified novel secreted proteins related to Notch1 expression. Soluble E-Cadherin (sE-Cad) and Thrombospondin-1 (Thbs1) were further validated in human serum as potential biomarkers to predict response to Notch1 inhibitors for a tailored individualized therapy.
Psychometric Synthesis of the Multicultural Counseling Inventory

Abstract This quantitative synthesis combines results of 72 studies that published psychometric information for the Multicultural Counseling Inventory. Although internal consistency, subsample means, and intrascale correlations provide promising evidence, convergent correlations with other instrumentation and factor analyses of validity continue to raise questions regarding measurement of the multicultural counseling competence construct.
A dense SNP-based genetic linkage map of grapevine ( Vitis vinifera L . ) anchoring Pinot Noir BAC contigs

The construction of a dense genetic map for Vitis vinifera and its anchoring to a BAC-based physical map is described: it includes 994 loci mapped onto 19 linkage groups, corresponding to the basic chromosome number of Vitis. Spanning 1,245 cM with an average distance of 1.3 cM between adjacent markers, the map was generated from the segregation of 483 SNP-based genetic markers, 132 SSRs, and 379 AFLP® markers in a mapping population of 94 F 1 individuals derived from a V. vinifera cross of the cultivars Syrah and Pinot Noir. Of these markers, 623 were anchored to 367 contigs which are included in a physical map produced from the same clone of Pinot Noir and covering 352 Mbp. Based on contigs containing two or more genetically mapped markers, region-dependent estimations of physical and recombinational distances are presented. The markers used in this study include 118 SSRs common to an integrated map derived from five segregating populations of V. vinifera. The positions of these SSR markers in the two maps are conserved across all Vitis linkage groups. The addition of SNP-based markers introduces polymorphisms that are easy to database, useful for evolutionary studies and that significantly increase the density of the map. The map provides the most comprehensive view of the Vitis genome reported to date and will be relevant for future studies on structural and functional genomics and genetic improvement.

Squeezed Condensate and Connnement in a Scalar Model Typeset Using Revt E X 1

In a simple Yukawa model of charged scalar quark elds coupled to scalar gluon elds a squeezed gluon condensate is constructed and an eeective Lagrangian for the quark sector derived. It is shown that the corresponding quark propagator has no poles on the real-k 2 axis which can be interpreted as quark connnement.
Dynamic Time Warping: Breaking the Quadratic Barrier

Dynamic Time Warping (DTW) is one of the basic similarity measures between curves or general temporal sequences (e.g., time series) that are represented as sequence of points in some metric space $(X, \operatorname{dist})$. The DTW measure is massively used in many practical fields of computer science, and computing the DTW between two sequences is a classical problem in P. Despite extensive efforts to find more efficient algorithms, the best-known algorithm for computing DTW is a long-standing dynamic programming algorithm that requires quadratic runtime, which is believed to be optimal, even for the one-dimensional case $X = \mathbb{R}$, which is perhaps one of the most used in practice. In this paper, we break the nearly 50 years old quadratic time bound for computing DTW between two sequences of $n$ points in $\mathbb{R}$, by presenting a deterministic algorithm that runs in $O\left( n^2 \log\log\log n / \log\log n \right)$ time. Our algorithm can be extended to work also for higher dimensional spaces $X = \mathbb{R}^d$, for any constant $d$, when the underlying distance-metric $\operatorname{dist}$ is polyhedral (e.g., $L_1$, $L_\infty$).
A comparison of the rates of progress between low achieving and high achieving fourth grade children using a whole language reading program

Author: M. Ayako Loder title: A comparison of the rates of progress between low achieving and high achieving fourth grade children using a whole language reading program. Date: May 1, 1996 Advisor: Stanley Urban, Ed. D. Program: Learning Disabilities, Track II Purpose: To study the rates of progress between low achieving and high achieving fourth grade children using a whole language reading program. Abstract: This study examined the rates of progress between low achieving and high achieving fourth grade children using a whole language reading program. Subjects were fourth grade students at a Bridgeton Elementary School, and grouped into low and high ability groups each containing 7 students. Reading instruction was provided during 90 minute class periods 5 times each week for 24 weeks. Instruction centered on reading short stories and trade books considered appropriate for fourth graders. Subjects completed a pre and post-test using the Kaufman Test of Educational Achievement in reading and spelling. A holistically scored writing example was coupleted in the fall and spring. Findings suggest that the high ability group improved or maintained their rate of progress. The low ability group progressed, but did not achieve an average standing in reading or writing, suggesting the need of a more integrated approach to reading incorporating a systematic phonics program.
Angular momentum-large-scale structure alignments in ΛCDM models and the SDSS

We study the alignments between the angular momentum of individual objects and the large-scale structure in cosmological numerical simulations and real data from the Sloan Digital Sky Survey, Data Release 6 (SDSS-DR6). To this end, we measure anisotropies in the two point cross-correlation function around simulated haloes and observed galaxies, studying separately the one- and two-halo regimes. The alignment of the angular momentum of dark-matter haloes in A cold dark matter (ACDM) simulations is found to be dependent on scale and halo mass. At large distances (two-halo regime), the spins of high-mass haloes are preferentially oriented in the direction perpendicular to the distribution of matter; lower mass systems show a weaker trend that may even reverse to show an angular momentum in the plane of the matter distribution. In the one-halo term regime, the angular momentum is aligned in the direction perpendicular to the matter distribution; the effect is stronger than for the one-halo term and increases for higher mass systems. On the observational side, we focus our study on galaxies in the SDSS-DR6 with elongated apparent shapes, and study alignments with respect to the major semi-axis. We study five samples of edge-on galaxies; the full SDSS-DR6 edge-on sample, bright galaxies, faint galaxies, red galaxies and blue galaxies (the latter two consisting mainly of ellipticals and spirals, respectively). Using the two-halo term of the projected correlation function, we find an excess of structure in the direction of the major semi-axis for all samples; the red sample shows the highest alignment (2.7 ± 0.8 per cent) and indicates that the angular momentum of flattened spheroidals tends to be perpendicular to the large-scale structure. These results are in qualitative agreement with the numerical simulation results indicating that the angular momentum of galaxies could be built up as in the Tidal Torque scenario. The one-halo term only shows a significant alignment for blue spirals (1.0 ± 0.4 per cent), consistent with the one-halo results from the simulation but with a lower amplitude. This could indicate that even though the structure traced by galaxies is adequate to study large-scale structure alignments, this would not be the case for the inner structure of low-mass haloes, M ≤ 10 13 h -1 M ⊙ , an effect apparently more important around red g - r > 0.7 galaxies.
Infants' Perceptions of Mothers Phone Use: Is Mothers' Phone Use Generating the Still Face Effect?

Using a modified still-face procedure the present study explores 3-6-month-old infants' behavioral and physiological responses to mothers' screen distractions during mother-infant interactions. In the modified phone still-face procedure the neutral face of the traditional still face procedure was replaced with mothers' texting on their mobile phones. Infants' cortisol stress responses to mothers' device use were assessed through the collection of 3 infant saliva samples. Infants' behavioral responses including facial expressions, vocalizations, gaze and self-comforting behaviors were also explored. All mother-infant interactions were videoed recorded and coded for analysis. Thirty-four mother-infant dyads participated, average ages for mothers was 29 years and 4.4 months for infants. As predicted, infants demonstrated the changes in affect associated with the still-face effect, with significant differences in positive and negative affect during the play phases and the phone still face phase. As a whole, infants did not respond with increased cortisol responses, however, when individual differences were explored 47% responded with increased stress during mothers' phone distractions. Mother's frequency and attitudes towards device use were also assessed but were unrelated to infant responses. Implications and directions for future research are discussed.
Optical and X-Ray Clusters as Tracers of the Supercluster-Void Network. I. Superclusters of Abell and X-Ray Clusters

We study the distribution of Abell and X-ray–selected clusters of galaxies and derive selection functions of these cluster samples. We find that selection functions and percolation properties of Abell clusters of richness class R = 0 and R ≥ 1 are similar; the percolation of X-ray clusters occurs at the same dimensionless radius as the percolation of Abell clusters. We present a new catalog of superclusters of Abell clusters out to a redshift of zlim = 0.13, a catalog of X-ray clusters located in superclusters determined by Abell clusters, and a list of additional superclusters of X-ray clusters. We investigate the distribution of X-ray–selected clusters of galaxies with respect to superclusters determined by Abell clusters of galaxies and show that the distribution of X-ray clusters follows the supercluster-void network determined by Abell clusters. We find that X-ray clusters are more strongly clustered than other clusters: the fraction of X-ray clusters is higher in rich superclusters, and the fraction of isolated X-ray clusters is lower than the fraction of isolated Abell clusters. Poor, non-Abell X-ray clusters follow the supercluster-void network as well: these clusters are embedded in superclusters determined by Abell clusters and populate filaments between them.
On the algebraic structure of the unitary group

We consider the unitary group $\mathbb{U}$ of complex, separable, infinite-dimensional Hilbert space as a discrete group. It is proved that, whenever $\mathbb{U}$ acts by isometries on a metric space, every orbit is bounded. Equivalently, $\mathbb{U}$ is not the union of a countable chain of proper subgroups, and whenever $\mathbb{E}\subseteq \mathbb{U}$ generates $\mathbb{U}$, it does so by words of a fixed finite length.
A single step analysis of plantar pressure distribution in tennis specific movements

Studies indicate that injury risks in tennis depend on the playing surface type. In order to assess loading during tennis specific movements, plantar pressure parameters are determined and analyzed. So far, only comparisons between whole stride sequences on different surfaces have been performed showing some inconsistent results. We assumed that on the more slippery clay higher vertical forces are required to accelerate, and that on hard-court higher loadings occur during deceleration. Hence, we analyzed the influence of the playing surface on respective types of steps. Eight experienced male tennis players performed two different tennis specific movements on clay and hard-court. We used a Pedar-X insole measurement system for determining selected plantar pressure parameters for the whole foot as well as for the forefoot and rear foot area. Steps were categorized as accelerating or decelerating regarding the path of the center of pressure during impact of the foot on the ground. For accelerating steps, a multivariate analysis revealed significant differences (Pillai-Spur; p < .05) for both repeated factors as well as their interaction for both playing conditions. All loading parameters were significantly higher in the forefoot area on clay for one of the two playing conditions investigated. For decelerating steps, the multivariate analysis revealed significant differences for both repeated factors for one playing condition. Higher values were observed for all loading parameters in the rear foot area in both playing conditions on clay. Running styles during tennis specific movements depend on the court surface. Separate analyses of acceleration and deceleration steps may help revealing high-risk parts and periods.
How fast can the wall move? A study of the electroweak phase transition dynamics.

We consider the dynamics of bubble growth in the minimal standard model at the electroweak phase transition and determine the shape and the velocity of the phase boundary, or bubble wall. We show that in the semiclassical approximation the friction on the wall arises from the deviation of massive particle populations from thermal equilibrium. We treat these with Boltzmann equations in a fluid approximation. This approximation is reasonable for the top quarks and the light species while it underestimates the friction from the infrared {ital W} bosons and Higgs particles. We use the two-loop finite temperature effective potential and find a subsonic bubble wall for the whole range of Higgs boson masses 0{lt}{ital m}{sub {ital H}}{lt}90 GeV. This result is weakly dependent on {ital m}{sub {ital H}}: the wall velocity {ital v}{sub {ital w}} falls in the range 0.36{lt}{ital v}{sub {ital w}}{lt}0.44, while the wall thickness is in the range 29{gt}{ital LT}{gt}23. The wall is thicker than the phase equilibrium value because out of equilibrium particles exert more friction on the back than on the base of a moving wall. We also consider the effect of an infrared gauge condensate which may exist in the symmetric phase; modeling it simplemore » mindedly, we find that the wall may become supersonic, but not ultrarelativistic. {copyright} 1995 The American Physical Society. « less
Determination of habitable zones in extrasolar planetary systems: Where are Gaia's sisters?

A general modeling scheme for assessing the suitability for life of extrasolar planets is presented. The scheme focuses on the identification of the “habitable zone” in main sequence star planetary systems accommodating Earth-like components. Our definition of habitability is based on the long-term possibility of photosynthetic biomass production under geodynamic conditions. Therefore all the pertinent astrophysical, climatological, biogeochemical, and geodynamic processes involved in the generation of photosynthesis-driven life conditions are taken into account. Implicitly, a cogenetic origin of the central star and the orbiting planet is assumed. A geostatic model version is developed and investigated in parallel for demonstration purposes. The numerical solution of the advanced geodynamic model yields realistic lookup diagrams for convenient habitability determination. As an illustration, the MACHO-98-BLG-35 event is scrutinized. It is shown that this event is definitely not tantamount to the discovery of one of Gaia's sisters.
Performance study of space-time trellis coded MC-CDMA system employing different detection techniques

In this paper, a space-time trellis-coded (STTC) multi-carrier code-division multiple-access (MC-CDMA) system for different states in multi-path fading channel is proposed, and the performance of the system is evaluated using simulation. The corresponding bit error rate (BER) is obtained using minimum mean-square error (MMSE), maximum-ratio combining (MRC), and equal-gain combining (EGC) receivers employing Viterbi decoder. The results of STTC-MC-CDMA system show that the improved performance can be achieved having 16 states STTC with the MMSE detector.
Abusive supervision and job outcomes: a moderated mediation study

Based on the conservation of resources theory, the purpose of this paper is to investigate the linkage between abusive supervision (a workplace stressor) and subordinate’s intention to quit by focusing on the mediating role of emotional exhaustion. The study also explores the conditional mediation model by testing the moderational role of perceived coworker support on the mediated abusive supervision-intention to quit relationship via emotional exhaustion. ,To test the proposed hypotheses, the study draws data from 382 healthcare employees working in several hospitals and clinics in the eastern and north-eastern states of India. The authors collected data on the predictor and criterion variables at two time points with a separation of three to four weeks in a reversed order to counter priming effect. ,The findings of the study reported that emotional exhaustion partially mediated the abusive supervision-intention to quit relationship. The result also supported the assertion that perceived coworker support will moderate the relationship between abusive supervision and subordinate’s intention to quit. The authors also found support to the moderated mediation hypothesis, that suggest perceived coworker support will reduce the mediating effect of abusive supervision-intention to quit relationship via emotional exhaustion. ,This study is among few empirical investigations to investigate and report the interactional effect of perceived coworker support (a buffer) on the indirect relationship between abusive supervision and subordinate’s intention to quit via emotional exhaustion.
Population pharmacokinetics and dosing simulations of cefuroxime in critically ill patients: non-standard dosing approaches are required to achieve therapeutic exposures.

OBJECTIVES To investigate the population pharmacokinetics of cefuroxime in critically ill patients. METHODS In this observational pharmacokinetic study, multiple blood samples were taken over one dosing interval of intravenous cefuroxime. Blood samples were analysed using a validated ultra HPLC tandem mass spectrometry technique. Population pharmacokinetic analysis and dosing simulations were performed using non-linear mixed-effects modelling. RESULTS One hundred and sixty blood samples were collected from 20 patients. CL(CR) ranged between 10 and 304 mL/min. A two-compartment model with between-subject variability on CL, V of the central compartment and V of the peripheral compartment described the data adequately. Twenty-four hour urinary CL(CR) was supported as a descriptor of drug CL. The population model for CL was CL = θ(1) × CL(CR)/100, where θ(1) is the typical cefuroxime CL in the population, which is 9.0 L/h. The mean V was 22.5 L. Dosing simulations showed failure to achieve the pharmacokinetic/pharmacodynamic target of 65% fT(>MIC) for an MIC of 8 mg/L with standard dosing regimens for patients with CL(CR) ≥50 mL/min. CONCLUSIONS Administration of standard doses by intermittent bolus is likely to result in underdosing for many critically ill patients. Continuous infusion of higher than normal doses after a loading dose is more likely to achieve pharmacokinetic/pharmacodynamic targets. However, even continuous infusion of high doses (up to 9 g per day) does not guarantee adequate levels for all patients with a CL(CR) of ≥300 mL/min if the MIC is 8 mg/L.
