10 Writing Opportunities to “Teach to the Test”
Authors: DeFauw Danielle L. 
Published: March 2013

AbstractWithin the current political and educative context, where high‐stakes standardized assessments create a pressure‐filled experience for teachers to “teach to the test,” time spent on writing instruction that supports students in transferring their learning between classroom and assessment contexts is crucial. Teachers who must use prompts to prepare students for standardized writing assessments can utilize writing contests and/or publication opportunities available on the Internet to prepare students for the context of standardized assessments. Contest writing can motivate students to practice writing to prompts for distant audiences. Ten websites are shared of organizations that host no fee writing contests and/or publishing opportunities for students to write in various fiction and/or nonfiction persuasive, explanatory, and narrative genres. The majority of these sites also post winning contest entries and/or publish anthologies/magazines of students’ writing that can be used as mentor texts for students to analyze and emulate to improve their writing.
Let Me Tell You a Secret: Kindergartners Can Write!
Authors: VanNess Amanda R. , Murnen Timothy J. , Bertelsen Cynthia D. 
Published: March 2013

ABSTRACTDuring her first two years of teaching, a kindergarten teacher (first author) developed a writing program grounded in five instructional strategies that repeatedly appear in emergent writing research—modeling, Scaffolded Writing, invented spelling, word walls, and reader response—and in the overarching principle of Gradual Release of Responsibility (Pearson & Gallagher, 1983). Using Gentry's Writing Scale (Gentry, 2005) as a frame for structuring her own observations and data collection, she illustrates how the writing program evolved and how it gets implemented in her classroom, and demonstrates the clear growth students made in one year using this approach.
Genetics research: jumping into the deep end of the pool
Authors: SHOMRON NOAM 
Published: March 2013

SummaryThe publication of the human genome, more than a decade ago, alongside the development of high-throughput technologies for DNA sequencing, marked the dawn of a new era in genetics. Large genomic projects have been initiated to decipher the mysteries hidden within the human genetic code. With the rapidly ever-growing amount of genetic information, and the importance of understanding what it all means, there is a need to generate an interdisciplinary hub that will connect researchers, both experimentalists and bioinformaticians, along with physicians and community representatives in order to develop a common genomic language. This should lead to an accessible, readable and interpretive human genome with a short list of personal actionable items. We will then be able to declare that we are moving ever closer to the point at which one's own genome will affect one's personal life at a scope beyond our current comprehension.
Weather effects on maize yields in northern China
Authors: SUN B. J. , VAN KOOTEN G. C. 
Published: March 2013

SUMMARYIn the present study, the effect of weather on maize yields in northern China was examined using data from 10 districts in Inner Mongolia and two in Shaanxi province. A regression model with a flexible functional form was specified on the basis of agronomic considerations. Explanatory variables included in the model were seasonal growing degree days, precipitation, technological change (e.g. adoption of new crop varieties, improved equipment, better management, etc.) and dummy variables to account for regional fixed effects. Results indicated that a fractional polynomial model in growing degree days could explain variability in maize yields better than a linear or quadratic model. Growing degree days, precipitation in July, August and September, and technological changes were important determinants of maize yields. The results could be used to predict potential maize yields under future climate change scenarios, to construct financial weather products and for policy makers to incentivize technological changes and construction of infrastructure (e.g. irrigation works) that facilitate adaptation to climate change in the agricultural sector.
Testing learner reliance on caption supports in second language listening comprehension multimedia environments
Authors: Leveridge Aubrey Neil , Yang Jie Chi 
Published: March 2013

AbstractListening comprehension in a second language (L2) is a complex and particularly challenging task for learners. Because of this, L2 learners and instructors alike employ different learning supports as assistance. Captions in multimedia instruction readily provide support and thus have been an ever-increasing focus of many studies. However, captions must eventually be removed, as the goal of language learning is participation in the target language where captions are not typically available. Consequently, this creates a dilemma particularly for language instructors as to the usage of captioning supports, as early removal may cause frustration, while late removal may create learning interference. Accordingly, the goal of the current study was to propose and employ a testing instrument, the Caption Reliance Test (CRT), which evaluates individual learners’ reliance on captioning in second language learning environments; giving a clear indication of the learners’ reliance on captioning, mirroring their support needs. Thus, the CRT was constructed comprised of an auditory track, accompanied by congruent textual captions, as well as particular incongruent textual words, to provide a means for testing. It was subsequently employed in an empirical study involving English as a Foreign Language (EFL) high school students. The results exhibited individual variances in the degree of reliance and, more importantly, exposed a negative correlation between caption reliance and L2 achievement. In other words, learners’ reliance on captions varies individually and lower-level achievers rely on captions for listening comprehension more than their high-level counterparts, indicating that learners at various comprehension levels require different degrees of caption support. Thus, through employment of the CRT, instructors are able to evaluate the degree to which learners rely on the caption supports and thus make informed decisions regarding learners’ requirements and utilization of captions as a multimedia learning support.
High blood manganese in iron-deficient children in Karachi
Authors: Rahman Mohammad Ataur , Rahman Bushra , Ahmed Nessar 
Published: March 2013

AbstractObjectiveDietary Fe deficiency has a high incidence in Pakistani children and may be associated with increased gastrointestinal absorption of trace metals such as Mn. Therefore, children residing in heavily polluted cities like Karachi may be prone to Mn toxicity. The present study investigated blood Mn concentrations in Karachi children of different Fe statuses.DesignA prospective observational study was conducted where children were classified into different categories of Fe status – normal Fe, borderline Fe deficiency, Fe deficiency and Fe-deficiency anaemia – using WHO criteria supported by measurements of soluble transferrin receptors. Blood Mn was determined for children in each category using graphite atomic absorption spectroscopy.SettingThree hospital outpatient departments in Karachi, Pakistan.SubjectsA total of 269 children (156 males, 113 females) aged 6–60 months from low-income families of Karachi.ResultsBlood Mn concentrations were significantly higher in children with Fe-deficiency anaemia and Fe deficiency compared with those of normal Fe status (both P < 0·01). Blood concentrations of soluble transferrin receptors were higher in children with Fe-deficiency anaemia compared with those of borderline or normal Fe status (both P < 0·05).ConclusionsThese findings report for the first time high blood Mn concentrations in Fe-deficient children of this age group. There is therefore an urgent need to identify and remove environmental exposure to Mn in combination with health strategies aimed at eradicating childhood Fe deficiency.
A Direct and Quantitative Three-Dimensional Reconstruction of the Internal Structure of Disordered Mesoporous Carbon with Tailored Pore Size
Authors: Balach Juan , Soldera Flavio , Acevedo Diego F. , Mücklich Frank , Barbero César A. 
Published: March 2013

AbstractA new technique that allows direct three-dimensional (3D) investigations of mesopores in carbon materials and quantitative characterization of their physical properties is reported. Focused ion beam nanotomography (FIB-nt) is performed by a serial sectioning procedure with a dual beam FIB-scanning electron microscopy instrument. Mesoporous carbons (MPCs) with tailored mesopore size are produced by carbonization of resorcinol-formaldehyde gels in the presence of a cationic surfactant as a pore stabilizer. A visual 3D morphology representation of disordered porous carbon is shown. Pore size distribution of MPCs is determined by the FIB-nt technique and nitrogen sorption isotherm methods to compare both results. The obtained MPCs exhibit pore sizes of 4.7, 7.2, and 18.3 nm, and a specific surface area of ca. 560 m2/g.
Two Fragments of ‘The Music of Luciano Berio’
Authors: OSMOND-SMITH DAVID , BERIO TALIA PECKER 
Published: March 2013

AbstractAt the time of his death in 2007 David Osmond-Smith had begun work on his second book on Luciano Berio. Planned as a more substantial volume than the earlier one (Oxford University Press, 1991), it aimed to combine what he termed ‘creative biography’ with a multidimensional view of the composer's output, seen through the lens of such categories as text and commentary, density and harmony, voice, and theatre. Published here is the only written-up chapter, covering the early part of the composer's life (1925–53), followed by the outline of the projected book. Preceding these fragments is an introductory note by Talia Pecker Berio. (CW)
The Art Ensemble of Chicago's ‘Get in Line’: Politics, Theatre, and Play
Authors: STEINBECK PAUL 
Published: March 2013

AbstractThe music of the Art Ensemble of Chicago was often considered to be politically oriented, and many of their performances addressed controversial political issues. However, these political moments were counter-balanced by public pronouncements in which the members of the group denied that their music was motivated by politics. I interrogate this seeming contradiction by analysing the Art Ensemble's ‘Get in Line’, a musical-theatrical piece from their 1969 albumA Jackson in Your House. ‘Get in Line’ critiques Vietnam-era militarism and racism, and simultaneously proposes that African Americans respond to these issues in politically unconventional, oppositional, even playful ways. In so doing, ‘Get in Line’ challenges essentialist views of black experimental music and shows how the Art Ensemble – like their colleagues in the Association for the Advancement of Creative Musicians (AACM) – prioritized pluralism and individual agency over orthodoxy, whether in politics or in aesthetics.
Identification of molecular hinge points mediating alternating access in the vesicular monoamine transporter VMAT2
Authors: Yaffe Dana , Radestock Sebastian , Shuster Yonatan , Forrest Lucy R. , Schuldiner Shimon 
Published: March 2013

Significance
Regulated release of neurotransmitters is made possible by activity of transporters that mediate their accumulation into synaptic vesicles. Vesicular monoamine transporter (VMAT), a member of the largest superfamily of transporters, mediates transport of monoamines. One of the structural features of these transporters is the pseudo symmetry between the first and the second half of the protein. We demonstrate the importance of two anchor points between these two domains that provide hinge points about which the two halves of the protein flex and straighten to open and close the translocation pathway, a process that enables alternating exposure of the substrate-binding site.

Published: March 2013

Significance
Reduced oxygen supply—hypoxia—is a near-universal feature of solid tumors that can alter how tumors respond to therapies. We investigated the transition from normoxia to hypoxia in model brain cancer systems, using single-cell proteomics and data analysis tools based on physicochemical concepts. This approach permits the simplification of otherwise complex biology. We find a hypoxia-induced switch within a mammalian target of rapamycin (mTOR) signaling network. At the switching point, mTOR is predicted, and then shown by experiment, to be unresponsive to inhibition. These results may help explain the undistinguished performance of mTOR inhibitors in certain clinical trials.

Published: March 2013

AbstractThe visual and microscopic tissue reactions to the absorbable monofilament Monocryl, absorbable monofilament triclosan‐coated Monocryl‐Plus, absorbable multifilament Vicryl, and nonabsorbable monofilament Prolene were evaluated for their use of surgical closure in Siberian Sturgeon Acipenser baerii. Postoperative assessments were conducted at 1, 2, 8, 12, and 26 and 55 weeks to visually evaluate the surgical incision for suture retention, incision healing, erythema, and swelling. Incisions were also assessed microscopically at 1, 2, and 8 weeks for necrosis, inflammation, hemorrhage, and fibroplasia. The results indicated that incisions closed with either Vicryl or Prolene suture materials were more likely to exhibit more erythema or incomplete healing compared with those closed with Monocryl or Monocryl‐Plus. The surgical implantation of a transmitter in the coelomic cavity did not significantly affect the response variables among the four suture materials. Monocryl or Monocryl‐Plus were equally effective and superior to other suture materials used for closing surgical incisions in Siberian Sturgeon or closely related species of sturgeon. Furthermore, Monocryl or Monocryl‐Plus may decrease the risk of transmitter expulsion through the incision, as surgical wounds appear to heal faster and exhibit less erythema compared with those closed with Vicryl.

Published: March 2013

Abstract
Pathogen-associated molecular pattern (PAMP)-trigged immunity (PTI) is the first defensive line of plant innate immunity and is mediated by pattern recognition receptors. Here, we show that a mutation in BR-SIGNALING KINASE1 (BSK1), a substrate of the brassinosteroid (BR) receptor BRASSINOSTEROID INSENSITIVE1, suppressed the powdery mildew resistance caused by a mutation in ENHANCED DISEASE RESISTANCE2, which negatively regulates powdery mildew resistance and programmed cell death, in Arabidopsis thaliana. A loss-of-function bsk1 mutant displayed enhanced susceptibility to virulent and avirulent pathogens, including Golovinomyces cichoracearum, Pseudomonas syringae, and Hyaloperonospora arabidopsidis. The bsk1 mutant also accumulated lower levels of salicylic acid upon infection with G. cichoracearum and P. syringae. BSK1 belongs to a receptor-like cytoplasmic kinase family and displays kinase activity in vitro; this kinase activity is required for its function. BSK1 physically associates with the PAMP receptor FLAGELLIN SENSING2 and is required for a subset of flg22-induced responses, including the reactive oxygen burst, but not for mitogen-activated protein kinase activation. Our data demonstrate that BSK1 is involved in positive regulation of PTI. Together with previous findings, our work indicates that BSK1 represents a key component directly involved in both BR signaling and plant immunity.
Development of a food safety verification risk model
Authors: Manning Louise 
Published: March 2013

PurposeThe purpose of this paper is to determine the mechanisms for effective verification of a food safety plan and reducing verification risk.Design/methodology/approachThe research involved analysis of both qualitative and quantitative methods of verification.FindingsEffective development of the food safety management system (FSMS) is underpinned by appropriate determination of food safety hazards, as well as the acceptable level of risk to the consumer and measures for their control. Product and process validation, and revalidation if required, is the key to consistently producing safe food and the development of appropriate real‐time monitoring activities. However, it is the development of effective verification processes for the FSMS and the pre‐requisite programme (PRP) and the reduction of verification risk that ensures that food safety is assured for consumers.Originality/valueThis research is of academic value and of value to those working in the food supply chain.

The paper was structured around key elements of Stephen's book, including the five waves of trust model which shows the different levels of trust and their inter‐dependence. It also covers the four cores of trust – integrity, intent, capability and results – which can raise credibility and build personal trust.FindingsThe paper shows the strategic importance of building trust levels within an organization. It also succeeds in highlighting how increased levels of trust help to remove obstacles to growth and progress.Originality/valueThe value of the paper is in its specific strategic focus and it will appeal to anyone with an interest in organizational performance and how this can be maximized.
Impact of health informatics on nurses' computer skills and the role of the library
Authors: Ajayi N.A. 
Published: March 2013

PurposeThe concept of the paper is how the library can be a useful framework for designing nurses' computer skills. The overarching aim of the research is to focus on how the computer skills involved in nurses' increasing access to health informatics can be used to improve nursing practice, consequently leading to better health care delivery. The objectives involved in achieving this aim include: finding out the level of nurses' computer literacy; finding out nurses' quest for electronic information for problem‐based nursing practice; investigating nurses' level of awareness of research‐based nursing practice; and finding out areas of desirability of informatics in nursing practice.Design/methodology/approachThe measuring instrument used was a self‐administered questionnaire to senior nursing cadres in the Teaching Hospitals Complex, Ile‐Ife, Nigeria. There were 230 nurses in these categories, of whom 180 were given questionnaires to fill in. The questionnaire was pre‐tested and validated. A total of 167 copies were returned and found to be usable. Simple percentages and a summation weighted index were used to analyse the data.FindingsThe paper provides empirical insight into nurses' computer skills and the library's role. The majority of the respondents did not have knowledge of computers; in the School of Nursing they learned it through various means while practising, while a few could access and retrieve information from the available databases. Some difficulties were expressed, such as workload, lack of skills, location of the library with regard to the hospital, etc. The desirability of the introduction of health informatics to the profession is high.Research limitations/implicationsThe study is limited to a teaching hospital and the results may not be generalisable to non‐teaching hospitals, hence the need for further studies.Practical implicationsThe impact of health informatics on nurses' computer skills and the library's role will save nurses from routine work, enhance their productivity, and will equip them better for the challenges that information technology presents for health professionals.Originality/valueThis paper fulfils and identifies the need to introduce health informatics to nursing practice in order to improve patient care.
The power of one: towards the new integrated organisation
Authors: Campbell Andrew , Strikwerda Hans 
Published: March 2013

PurposeThis paper seeks to address the problem facing complex multinational companies: how to balance their organisation structure across the competing interests such as product, geography, brand, function and key account.Design/methodology/approachThe research involved interviews with large companies such as ABNAmro, Albert Heijn, ASML, and IBM.FindingsThe findings suggest that some companies are starting to find solutions to the structural challenges of multi‐dimensional complexity by integrating selected aspects of the organisation: the overarching logic, the information base, the process for selecting opportunities, the profit measure and the management mindset. These “power of one” solutions point a possible way through organisational complexity.Practical implicationsLeaders often launch “one company” projects; this paper will help them define what should be part of such a project, and help them understand the size of the task ahead of them if they want to create a fully integrated organisation.Originality/valueThe paper presents some new perspectives on how leaders appear to be solving the problems of multidimensional structures.
