AbstractSix acentric tartrates and tartrato-antimonates have been investigated by means of X-ray powder diffraction. Single crystals were obtained by evaporation from aqueous solutions. The compounds have attracted attention because of their electrostrictive and electro-optical effects. Complete crystal data for the six compounds are reported. X-ray powder diffraction patterns for Rb2C4H4O6and Ca [Sb2{C4H2O6}2]·2H2O are given.
Precise Angular Control of Quartz-Cutting by X-Rays
Authors: Parrish William , Gordon Samuel 
Published: January 2013

AbstractMethods for precise control of the cutting angles of quartz by x-ray measurements are described. The quartz must first be oriented by some other method (usually optically) before the x-ray method can be applied. The sense of direction of the cut is indicated by an arrow drawn on the outer surface of the test cut at the saw and this direction is preserved in making the x-ray measurement. The x-ray technique is an adaptation of the Bragg ionization chamber method and involves measuring the angle between the surface of the test cut or blank and an atomic reference plane parallel (or nearly parallel) to the surface. All measurements are direct, and require no computation. A Gieger-Muller tube operated in the proportional counter region is employed. Accuracy of the method is approximately ±1.5′, the measurement requires about 10-15 seconds, and is used by unskilled help. The procedures for calibrating the x-ray goniometer and measuring various types of cuts are described in detail. Methods involving precise angular adjustments of sections approximately oriented by other methods and the use of reflection intensity differences of certain planes on either side of the optic axis for detecting usable portion of electrical twins and negative and positive directions from Z are described. The methods are applicable to other fields.

Authors: Burns Peter C. , Hawthorne Frank C. 
Published: January 2013

AbstractThe crystal structure of monoclinic CuF2 has been refined by the Rietveld method from X-ray powder diffraction data. The structure is monoclinic, space group P21/n, a = 3.2973(2), b = 4.5624(3), c = 4.6157(3) Å, β = 83.293(3)°, V = 68.96(2) Å3, with Cu+2 at (0,0,0) and F−1 at (−0.04176(68), 0.29410(35), 0.29410(35)). Final RB = 0.97%, RP = 1.99%, Rwp = 2.32%, RWP(expected) = 1.46%. The structure has a rutile-type arrangement, but with a monoclinic distortion that produces a highly distorted octahedral coordination around the Cu2+ ion with equatorial and apical Cu-F distances of 1.92 and 2.32 Å respectively.
Angular Corrections for the Seemann-Bohlin X-Ray Diffractometer
Authors: Rafaja D. , Valvoda V. 
Published: January 2013

AbstractA method for the correction of peak position for the Seemann-Bohlin X-ray diffractometer, useful for practical application, is presented. The position of diffraction peaks is largely influenced by both the displacement of specimen from the diffractometer circle and the shift of the X-ray tube focus. The described correction method has been used for investigation of thin layers, especially for the precise determination of both lattice parameter and stresses in thin films. The application of the method is illustrated on samples of TiN and ZrN coatings deposited on steel substrates and additionally covered with a thin film of Si or Ta or TaC powder used as an internal standard.
The Determination of Low Levels of Quartz in Commercial Kaolins by X-ray Diffraction
Authors: Elton N.J. , Salt P.D. , Adams J.M. 
Published: January 2013

AbstractLegislation in the United States and Canada requires labelling of products containing ≥ 0.1 wt.% crystalline silica. Kaolin clays are used in a variety of industries and usually contain low levels of total (i.e., respirable plus non-respirable) quartz, even after beneficiation. X-ray diffraction procedures have been developed here which are suitable for the quantification of total quartz in commercial kaolins with accuracy sufficient to satisfy the legislation. Separation and analysis of the respirable fraction is not addressed in this paper; however, the procedures described would be applicable to such samples if sufficient were available. Use of the 50.1° 2θrather than the 26.6° 26 (CuKα) quartz peak avoids most of the potential problems of overlap with reflections from other accessory minerals. It is shown that profile fitting techniques and optimised experimental procedures allow the determination of quartz in bulk samples to ± 0.03 wt.% (95% confidence) at the 0.1 wt.% level, and ± 0.1 wt.% at the 1.0 wt.% level, with tolerable data collection times.
Notes on Slits and Monochromators in Accurate Powder Diffractometry
Authors: Timmers J. , van der Pers N.M. , Sprong G.J.M. , de Keijser Th.H. , Delhez R. 
Published: January 2013

AbstractLimitations in powder diffractometry imposed by scatter slits and/or a diffracted-beam monochromator, which have been ignored in the past, are discussed and mapped quantitatively. These limitations become manifest especially with ωoffsets, i.e.in stress measurements and with ωoscillation to improve the reproducibility of intensities in the presence of too coarse grains. The limitations can only be established with knowledge of slit sizes and with precise alignment of all slits, their holders and the diffracted-beam monochromator. To that end, concise, accurate procedures for obtaining these measurements in-situare proposed.

Published: January 2013

AbstractThe results of an international project involving five countries and seven laboratories performing over 400 analyses for testing the interlaboratory reproducibility and accuracy using quantitative powder diffraction are presented in this report. Four natural and four artificial mineral mixtures were examined. The RIR (reference intensity ratio) values for all mineral components were either measured or calculated. The relative standard deviation of the interlaboratory determinations range from 5 to 20 percent (for low concentrations, the relative standard deviations can attain 60% percent). Due to systematic errors, the relative standard deviations of the interlaboratory determinations generally exceed the standard deviations determined by individual laboratories. The best results were obtained when the RIR values were measured independendy in each laboratory.
About Instrument-, Method- and Matrix-Independence in the Working Equations of the Quantitative X-Ray Analysis
Authors: Zangalis K. P. 
Published: January 2013

AbstractIn most of the practical problems of the quantitative X-ray analysis, obtaining working equations including only intensity ratios without the sample mass-absorption coefficient is impossible, unless an internal standard is added to the sample. It is shown that the internal standard may be unnecessary if some chemical data are added to the XRD information used. Experimental results justify this claim.

Emergency Department Organisation for Disasters: A Review of Emergency Department Disaster Plans in Public Hospitals of Singapore
Authors: Lee Francis Chun Yue , Goh Siang Hiong , Wong Ho Poh , Anantharaman V. 
Published: January 2013

AbstractDisaster management plans of emergency departments (EDs) in four major public hospitals were reviewed. A comparison was made between these plans, and they were analyzed to gain an understanding of the differing objectives and doctrines behind the practices. These were summarized into five major management concepts, which are considered to be critical to the success of a disaster plan: 1) staff mobilization systems (cascading vs batch mobilization); 2) staff deployment systems; 3) team organization (surgeons vs residents); 4) area management (the role of the area manager); 5) casualty volume management (accommodation vs expansion vs extension concepts). The-concepts derived should serve as a useful guide to the development of an ED disaster plan and potentially influence how new ED facilities could be planned.
The Development and Evaluation of a Paramedic-Staffed Mobile Intensive Care Unit for Interfacility Patient Transport
Authors: Domeier Robert M. , Hill James D. , Simpson Roger D. 
Published: January 2013

AbstractObjective:As the role of paramedics evolves, evaluation of their ability to accomplish an expanded scope of practice is necessary. The objective of this study was to determine whether specially trained paramedics can monitor and treat patients appropriately during interfacility transports that traditionally have required the use of supplemental, hospital-based personnel.Methods:A paramedic-staffed mobile intensive care unit was developed as a cooperative program between Huron Valley Ambulance and the Washtenaw/Livingston County Medical Control Authority. This prospective observational study involved 111 patients requiring interfacility transport, conveyed by a paramedic-staffed mobile intensive care unit. A change in the Acute Physiologic and Chronic Health Evaluation (APACHE II) score components of mean arterial pressure, heart rate, and respiratory rate at the beginning and end of the transport was used to evaluate the ability of the paramedics to accomplish the transfer appropriately.Results:APACHE II scares increased in 20 patients, decreased in 16, and were unchanged in 75. The mean value for the change in APACHE score was 0.11 (95% confidence interval: −0.11−0.33).Conclusion:Specially trained paramedics can monitor and treat patients appropriately during interfacility transfers that traditionally would have required supplementation with additional hospital staff.
Analysis of Biologically-Derived Small Particles—Searching for Geometry Correction Factors Using Monte Carlo Simulation
Authors: Tylko Grzegorz 
Published: January 2013

AbstractA Monte Carlo simulation was used to determine geometry correction factors that increase accuracy of quantitative X-ray microanalysis of laterally semithick biological materials. A model composed of cellulose with homogeneously distributed biological elements and lateral dimensions between 0.5–25 μm was chosen. The specimen was exposed to 5, 10, and 15 keV electrons, the net intensities of characteristic X-rays registered for the elements, and presented as a function of the lateral dimensions of the model. This showed the double decay exponential function fitted the distribution of X-ray intensities in relation to the model size. The applicability of the function as a correction method was successfully tested for 30 specimens with varying composition and dimensions. The value of relative error decreased from ±60% to ±5% when the correction was applied. Moreover, the minimal lateral size of the material was defined, below which the correction is not required. The simulation also revealed that the difference of the weighted sum ofZ2/Abetween the unknown and the standard could reach 25% without significant influence on the quantitative results. The correction method could be helpful for accurate assessment of elemental composition in biological or organic matrices, when their lateral dimensions are smaller than the distribution range.

Published: January 2013

Abstract
Ticks transmit a variety of viral, bacterial and protozoal pathogens, which are often zoonotic. The aim of this study was to identify diverse tick microbiomes, which may contain as-yet unidentified pathogens, using a metagenomic approach. DNA prepared from bacteria/archaea-enriched fractions obtained from seven tick species, namely Amblyomma testudinarium, Amblyomma variegatum, Haemaphysalis formosensis, Haemaphysalis longicornis, Ixodes ovatus, Ixodes persulcatus and Ixodes ricinus, was subjected to pyrosequencing after whole-genome amplification. The resulting sequence reads were phylotyped using a Batch Learning Self-Organizing Map (BLSOM) program, which allowed phylogenetic estimation based on similarity of oligonucleotide frequencies, and functional annotation by BLASTX similarity searches. In addition to bacteria previously associated with human/animal diseases, such as Anaplasma, Bartonella, Borrelia, Ehrlichia, Francisella and Rickettsia, BLSOM analysis detected microorganisms belonging to the phylum Chlamydiae in some tick species. This was confirmed by pan-Chlamydia PCR and sequencing analysis. Gene sequences associated with bacterial pathogenesis were also identified, some of which were suspected to originate from horizontal gene transfer. These efforts to construct a database of tick microbes may lead to the ability to predict emerging tick-borne diseases. Furthermore, a comprehensive understanding of tick microbiomes will be useful for understanding tick biology, including vector competency and interactions with pathogens and symbionts.
A Social Communication Intervention to Increase Validating Comments by Children With Language Impairment
Authors: Fujiki Martin , Brinton Bonnie , McCleave Chelsea P. , Anderson Valyne W. , Chamberlain Janet P. 
Published: January 2013

Purpose
Four children identified with language impairment (LI) participated in a social communication intervention to increase the production of validating comments, including making positive statements, sharing information, and asking peers questions about themselves.

Method
A case study design was used. Baseline measures were collected from 3 cooperative learning sessions for each participant. The intervention lasted 10 weeks, with 40 (15-min) sessions for 3 of the children and 20 (30-min) sessions for the remaining child. Each week, participants took part in sessions of group instruction, novel peer play, and review with the clinician. Data monitoring the production of validating comments were taken from the novel peer play interactions.

Results
One child produced a notable increase in validating comments during intervention, and 2 other participants produced more modest improvement. All 3 maintained these gains in the follow-up sessions. The remaining participant produced little change from baseline during the intervention. With respect to social outcomes, changes were not noted in peer acceptance and friendship. Teachers reported notable improvement in the sociable behavior of 2 of the children.

Conclusion
The 4 participants showed varied increases in the production of validating comments. Possible factors influencing the successful application of the intervention are discussed.
Fragment recruitment on metabolic pathways: comparative metabolic profiling of metagenomes and metatranscriptomes
Authors: Desai Dhwani K. , Schunck Harald , Löser Johannes W. , LaRoche Julie 
Published: January 2013

Abstract
Motivation: The sheer scale of the metagenomic and metatranscriptomic datasets that are now available warrants the development of automated protocols for organizing, annotating and comparing the samples in terms of their metabolic profiles. We describe a user-friendly java program FROMP (Fragment Recruitment on Metabolic Pathways) for mapping and visualizing enzyme annotations onto the Kyoto Encyclopedia of Genes and Genomes (KEGG) metabolic pathways or custom-made pathways and comparing the samples in terms of their Pathway Completeness Scores, their relative Activity Scores or enzyme enrichment odds ratios. This program along with our fully configurable PERL-based annotation organization pipeline Meta2Pro (METAbolic PROfiling of META-omic data) offers a quick and accurate standalone solution for metabolic profiling of environmental samples or cultures from different treatments. Apart from pictorial comparisons, FROMP can also generate score matrices for multiple meta-omics samples, which can be used directly by other statistical programs.

Registration and Replication: A Comment
Authors: Anderson Richard G. 
Published: January 2013

Social scientists long have debated how closely their research methods resemble the pure, classical ideal: sequentially (and absent pejorative “data snooping”) formulate a theory; develop empirically falsifiable hypotheses; collect data; and conduct the appropriate statistical tests. Meanwhile, in private quarters, they acknowledged that true research seldom proceeds in this fashion. Rather, in the event, the world is observed, data are collected, hypotheses formed, tests conducted, more data collected, and hypotheses revised (e.g., the classic Bernal 1974). Results are collected by the field's scientists into a body of knowledge that defines “known science” and sets the accepted boundaries for future research. Kuhn (1970) labeled this a paradigm. Occasionally, he argued, results appear that lie outside the bounds of the extant paradigm—then, innovation occurs.The articles included in this issue's symposium discuss “registration” of empirical studies. The purpose is to reduce “publication bias,” that is, to prevent the scientific equivalent of schoolboy cheating: reporting tests of hypotheses that became evident only after the data were in hand. Registration has little power against the type of research fraud that is discovered from time to time. There are costs, however, when scientists operating within an accepted paradigm discourage researchers from exploring and reporting any/all relationships and correlations in a data set.
All the world wide web's a stage
Authors: Thornton David E. , Kaya Ebru 
Published: January 2013

PurposeThe purpose of this article is to describe a collaborative project organised by Bilkent University Library, Turkey, to produce a series of instructional videos that are both informative and entertaining and also serve to market the library.Design/methodology/approachThe paper will outline the theoretical basis for the use of videos for library instruction, especially with reference to the habits and preferences of so‐called Generation Y students and to the potential value of video for facilitating memory and learning.FindingsThe use of humorous and interesting content, in a dramatised style, were found to improve Generation Y students' learning and enjoyment of instructional videos.Practical implicationsThe development of the project demonstrates the practical and marketing benefits of collaboration by academic librarians with students and faculty. However, it proved more difficult to evaluate the efficiency of the final product in terms of influencing the attitude of students toward the library and library resources and thereby changing their behaviour when studying.Originality/valueThe authors recommend that such library videos should definitely form part of an academic library's information literacy programme, but should not constitute the sole element.

PurposeThe purpose of this paper is to examine characteristics of project management assets and project management performance outcomes as a step towards exploring the link between assets being valuable, rare, inimitable, and having organizational support and the achievement of competitive advantage.Design/methodology/approachThis paper analyzes data from responses to an online survey by 198 North American Project Management Institute®members. Exploratory factor analysis is used to identify characteristics of project management assets and project management performance outcomes.FindingsIn total, six factors that comprised the characteristics of project management assets, three factors that comprised organizational support for project management assets, and two factors that comprised the project management performance outcomes were extracted.Research limitations/implicationsLimitations of this study include sample size, response rate, and self‐report bias, calling for a larger sample in ongoing research. This study is a step towards making the link between project management assets and performance outcomes.Practical implicationsThis study draws managerial attention to project management assets as sources of competitive advantage, applying the resource based view of the firm that assets are sources of competitive advantage if they add economic value, are rare, are difficult to imitate, and have organizational support.Originality/valueFew papers have applied the resource based view of the firm to examine project management capabilities as a source of competitive advantage. This paper contributes to the literature on the resource based view of the firm and contributes to an improved understanding of project management as a source of competitive advantage.
