Research Note: Students as Evaluators of Writing: Learning from What They Notice

Based on the premise that teachers gain useful insights by considering what students notice when evaluating a written text, this pilot project reports on the implementation of an evaluative activity with one group of students and considers the implications of the results for classroom practice. Thirteen students in a university-level Spanish composition class completed three stages of data collection; they identified strong and weak points of a sample composition, shared their assessments in a class discussion, and completed reflective questionnaires focused on perceptions of writing. Of their 86 observations, 19 were focused on technical issues of grammar/mechanics and 24 on communicative issues of argumentation. The manner in which learners presented those features also provides insight into their perceptions. Certain features, inclusion of personal opinion, use of person, and traditional three-part organisation, were sometimes framed as hard-and-fast rules; participants did not always mention their value as communicative tools. Other participants took a critical perspective that considered the role of features like organisation and spelling in the effective communication of a written message. Results indicate that attending to what learners notice has potential as a pedagogical tool.
Effect of Spam on Hashtag Recommendation for Tweets

Presence of spam tweets in a dataset may affect the choices of feature selection, algorithm formulation, and system evaluation for many applications. However, most existing studies have not considered the impact of spam tweets. In this paper, we study the impact of spam tweets on hashtag recommendation for hyperlinked tweets (i.e., tweets containing URLs) in HSpam14 dataset. HSpam14 is a collection of 14 million tweets with annotations of being spam and ham (i.e., non-spam). In our experiments, we observe that it is much easier to recommend "correct" hashtags for spam tweets than ham tweets, because of the near duplicates in spam tweets. Simple approaches like recommending most popular hashtags achieves very good accuracy on spam tweets. On the other hand, features that are highly effective on ham tweets may not be effective on spam tweets. Our findings suggest that without removing spam tweets from the data collection (as in most studies), the results obtained could be misleading for hashtag recommendation tasks.
Extensive Postoperative Epidural Hematoma After Full Anticoagulation: Case Report and Review of the Literature

Abstract Background/Objective: A 67-year-old man with degenerative lumbar spinal stenosis and a medical history significant for coronary artery disease underwent routine lumbar surgical decompression. The objective of this study was to report a case of postoperative epidural hematoma associated with the use of emergent anticoagulation, including the dangers associated with spinal decompression and early postoperative anticoagulation. Methods: Case report. Findings: After anticoagulation therapy for postoperative myocardial ischemia, the patient developed paresis with ascending abdominal paraesthesias. Immediate decompression of the surgical wound was carried out at the bedside. Magnetic resonance imaging revealed a massive spinal epidural hematoma extending from the middle of the cervical spine to the sacrum. Emergent cervical, thoracic, and revision lumbar laminectomy without fusion was performed to decompress the spinal canal and evacuate the hematoma. Results: Motor and sensory function returned to normal by 14 days postoperatively, but bowel and bladder function continued to be impaired. Postoperative radiographs showed that coronal and sagittal spinal alignment did not change significantly after extensive laminectomy. Conclusions: Full anticoagulation should be avoided in the early postoperative period. In cases requiring early vigorous anticoagulation, patients should be closely monitored for changes in neurologic status. Combined cervical, thoracic, and lumbar laminectomy, without instrumentation or fusion, is an acceptable treatment option.
Contact allergy to ‘bible leaf’ used in folk medicine

Tanacetum balsamita [syn. Chrysanthemum tanacetum, Chrysanthemum majus, bible leaf (USA), Costmary, or Alecost (England)] belongs to the Compositae (Asteraceae) plant family. Contact allergy to plants used to be an occupational disease (1), but because of the increasing popularity of herbal remedies, the incidence of contact dermatitis is being observed more frequently (2, 3). We report the case of a patient applying this ‘medicinal’ plant to treat a posttraumatic injury.
Mechanism of n-butyrate uptake in the human proximal colonic basolateral membranes.

Current studies were undertaken to characterize the mechanism of short-chain fatty acid (SCFA) transport in isolated human proximal colonic basolateral membrane vesicles (BLMV) utilizing a rapid-filtration n-[(14)C]butyrate uptake technique. Human colonic tissues were obtained from mucosal scrapings from organ donor proximal colons. Our results, consistent with the existence of a HCO(3)(-)/SCFA exchanger in these membranes, are summarized as follows: 1) n-[(14)C]butyrate influx was significantly stimulated into the vesicles in the presence of an outwardly directed HCO(3)(-) and an inwardly directed pH gradient; 2) n-[(14)C]butyrate uptake was markedly inhibited (approximately 40%) by anion exchange inhibitor niflumic acid (1 mM), but SITS and DIDS (5 mM) had no effect; 3) structural analogs e.g., acetate and propionate, significantly inhibited uptake of HCO(3)(-) and pH-gradient-driven n-[(14)C]butyrate; 4) n-[(14)C]butyrate uptake was saturable with a K(m) for butyrate of 17.5 +/- 4.5 mM and a V(max) of 20.9 +/- 1.2 nmol x mg protein(-1) x 5 s(-1); 5) n-[(14)C]butyrate influx into the vesicles demonstrated a transstimulation phenomenon; and 6) intravesicular or extravesicular Cl(-) did not alter the anion-stimulated n-[(14)C]butyrate uptake. Our results indicate the presence of a carrier-mediated HCO(3)(-)/SCFA exchanger on the human colonic basolateral membrane, which appears to be distinct from the previously described anion exchangers in the membranes of colonic epithelia.
Portrayal of the Slow Food movement in the Australian print media

The Slow Food movement promotes itself as supporting ethical modes of food production and consumption. This article reports on research that investigated the representations of the movement in the Australian print media, exploring the discourses relating to Slow Food and examining whether the media exposure is positively or negatively framed. A content and discourse analysis was undertaken of articles on Slow Food over a three-month period. The analysis aimed to provide a contextual basis for how Slow Food is perceived, the messages it conveys, and the activities it undertakes. Major themes arising from the data were ‘conviviality’ (social pleasures of sharing ‘good food’), ‘localism’ (social, health and environmental benefits of local produce), and ‘romanticism’ (of idyllic rural lifestyles as an antidote to the time-poverty of urban life). The findings shed light on the role played by the print media in reproducing and creating public understandings of the Slow Food movement.
Are the treasures of game theory ambiguous?

Goeree and Holt (Am Econ Rev 91:1402–1422, 2001) experimentally study a number of games. In each case, they initially find strong support for Nash equilibrium; however, by changing an apparently irrelevant parameter, they find results which contradict Nash equilibrium. In this paper, we study the five normal form games from Goeree and Holt (Am Econ Rev 91:1402–1422, 2001). We argue that their results may be explained by the hypothesis that subjects view their opponents’ behaviour as ambiguous. Ambiguity-aversion causes players to avoid strategies, which give low out of equilibrium payoffs. Similarly, ambiguity preference can make strategies with high payoffs more attractive.
Review of Pasteuria penetrans: Biology, Ecology, and Biological Control Potential.

Pasteuria penetrans is a mycelial, endospore-forming, bacterial parasite that has shown great potential as a biological control agent of root-knot nematodes. Considerable progress has been made during the last 10 years in understanding its biology and importance as an agent capable of effectively suppressing root-knot nematodes in field soil. The objective of this review is to summarize the current knowledge of the biology, ecology, and biological control potential of P. penetrans and other Pasteuria members. Pasteuria spp. are distributed worldwide and have been reported from 323 nematode species belonging to 116 genera of free-living, predatory, plant-parasitic, and entomopathogenic nematodes. Artificial cultivation of P. penetrans has met with limited success; large-scale production of endospores depends on in vivo cultivation. Temperature affects endospore attachment, germination, pathogenesis, and completion of the life cycle in the nematode pseudocoelom. The biological control potential of Pasteuria spp. have been demonstrated on 20 crops; host nematodes include Belonolaimus longicaudatus, Heterodera spp. , Meloidogyne spp. , and Xiphinema diversicaudatum. Pasteuria penetrans plays an important role in some suppressive soils. The efficacy of the bacterium as a biological control agent has been examined. Approximately 100,000 endospores/g of soil provided immediate control of the peanut root-knot nematode, whereas 1,000 and 5,000 endospores/g of soil each amplified in the host nematode and became suppressive after 3 years.
Cryopreserved human hepatocytes as alternative in vitro model for cytochrome P450 induction studies

SummaryInduction of cytochrome P450 (CYP) by drugs is one of major concerns for drug-drug interactions. Thus, the assessment of CYP induction by novel compounds is a vital component in the drug discovery and development processes. Primary human hepatocytes are the preferred in vitro model for predicting CYP induction in vivo. However, their use is hampered by the erratic supply of human tissue and donor-to-donor variability. Although cryopreserved hepatocytes have been recommended for short-term applications in suspension, their use in studies on induction of enzyme activity has been limited because of poor attachment and response to enzyme inducers. In this study, we report culture conditions that allowed the attachment of cryopreserved human hepatocytes and responsiveness to CYP inducers. We evaluated the inducibility of CYP1A1/2 and CYP3A4 enzymes in cryopreserved hepatocytes from three human donors. Cryopreserved human hepatocytes were cultured in serum-free medium for 4 d. They exhibited normal morphology and measurable viability as evaluated by the reduction of tetrazolium salts (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium inner salt) by cellular dehydrogenases. Treatment with β-naphthoflavone (10 μM) for 3 d increased ethoxyresorufin-O-deethylase activity (CYP1A1/2) by 6- to 11-fold over untreated cultures and increased CYP1A2 messenger ribonucleic acid (mRNA) expression by three- to eightfold. Similarly, treatment of cryopreserved human hepatocytes with rifampicin (25 μM) for 3 d increased testosterone 6β-hydroxylase activity (CYP3A4) by five- to eightfold over untreated cultures and increased CYP3A4 mRNA expression by four- to eightfold. The results suggest that cryopreserved human hepatocytes can be a suitable in vitro model for evaluating xenobiotics as inducers of CYP1A1/2 and CYP3A4 enzymes.
What can bibliometrics tell us about changes in the mode of knowledge production?

One of the most influential contributions to the fields of science policy research and science and technology studies during the last 20 years was The New Production of Knowledge by Gibbons et al. (Gibbons, M., Limoges, C., Nowotny, H., Schwartzman, S., Scott, P. and Trow, M. (1994) The New Production of Knowledge: The Dynamics of Science and Research in Contemporary Societies, Sage, London). The authors argued that over recent decades a different form of knowledge production has emerged, one which they termed ‘Mode 2’. In this, knowledge is produced in the context of application, generally on the basis of transdisciplinary research efforts, by a heterogeneous range of institutional actors, who are subject to wider social accountability and more diverse forms of quality control than in the traditional ‘Mode 1’ knowledge production. Although there have been a number of attempts to examine the claims of The New Production of Knowledge empirically, the evidence is, at best, rather ambiguous. The study reported here analyses highly cited publications in the field of bibliometric research to establish whether the themes of those publications and, more specifically, the changes in these themes over the last 20 years, provide any evidence of a growing incidence of Mode 2 knowledge production. The paper concludes that there is some evidence that bibliometrics, as a field of research, has exhibited a shift towards Mode 2 knowledge production over the last two decades. In addition, it would seem to have played a part in a similar shift across science more generally, offering policy-relevant tools and analyses, helping scientific research to respond to increased demands for accountability, and contributing to changes in the approach to the quality assessment of research. At the same time, and perhaps inadvertently, it may have contributed to bringing about changes in publication and citation practices as more and more authors seek to maximise their ‘score’ on one or more bibliometric indicators.
A State Transition MIP Formulation for the Unit Commitment Problem

In this paper, we present the state-transition formulation for the unit commitment (UC) problem. This formulation uses new decision variables that capture the state transitions of the generators, instead of their on/off statuses. We show that this new approach produces a formulation which naturally includes valid inequalities, commonly used to strengthen other formulations. We demonstrate the performance of the state-transition formulation and observe that it leads to improved solution times especially in longer time-horizon instances. As an important consequence, the new formulation allows us to solve realistic instances in less than 12 minutes on an ordinary desktop PC, leading to a speed-up of a factor of almost two, in comparison to the nearest contender. Finally, we demonstrate the value of considering longer planning horizons in UC problems.
Commentary: The icmF3 Locus is Involved in Multiple Adaptation- and Virulence-related Characteristics in Pseudomonas aeruginosa PAO1

A commentary on The icmF3 locus is involved in multiple adaptation-and virulence-related characteristics in Pseudomonas aeruginosa PAO1 Pseudomonas aeruginosa is an important pathogen commonly isolated from patients with burns, wounds and cystic fibrosis (Lyczak et al., 2000; Gellatly and Hancock, 2013). The P. aeruginosa strain PAO1 was originally reported as a wound isolate from a patient in Australia in 1955 (Holloway, 1955), and has since been studied in many laboratories as a reference strain (Stover et al., 2000). However, a number of genetic variants of PAO1 in different laboratories have been reported including a large 2.2 Mb inversion and a number of single nucleotide variants and insertion-deletion mutations (Stover et al., 2000; Heurlier et al., 2005; Klockgether et al., 2010). The type 6 secretion system (T6SS) functions as a molecular weapon that delivers toxic effectors to prokaryotic and eukaryotic target cells (Ho et al., 2014). The T6SS was first functionally characterized in Vibrio cholerae and P. The T6SS main structure consists of an outer sheath, an inner tube, and a membrane-bound anchor complex (Basler, 2015). Contraction of the outer sheath ejects the inner tube and its associated effector proteins to the extracellular environment (Ho et al., 2014; Basler, 2015). IcmF, a key T6SS protein, carries an ATPase domain (Ma et al., 2012) and interacts with TssL and TssJ to form a membrane-spanning complex with a hollow space that allows the inner tube and effectors to travel through (Basler, 2015; Durand et al., 2015). The recently published paper by Lin et al. (Lin et al., 2015) reported multiple interesting yet moderate phenotypes associated with the IcmF3 of the H3-T6SS, including iron acquisition, bacterial killing, motility, antibiotic resistance, and virulence. However, the molecular mechanism of IcmF3 involvement in such diverse cellular processes is not clear. Because IcmF is required for T6SS assembly, those reported phenotypes suggest a broad versatile role of the H3-T6SS in PAO1
Limitation of the short-circuit ruggedness of high-voltage IGBTs

In this paper, the destruction mechanism, which limits the short-circuit capability of high voltage IGBTs utilizing N-buffer structures will be described. The failure mechanism was studied using a combination of device simulations and experimental investigations of 3.3kV, 4.5kV and 6.5kV IGBTs. It was found that the limiting short-circuit failure in these IGBTs is caused by a current filamentation mechanism, which is associated to a distortion of the electric field triggered by a positive feedback effect between the carrier drift velocities and the electric field and the resulting potential distribution in the IGBT N-base.
Diffusion tensor imaging in temporal lobe epilepsy

Although mesial temporal sclerosis (MTS) has long been recognized in association with temporal lobe epilepsy (TLE), there is a growing body of literature suggesting structural abnormalities extending beyond the temporal lobe in patients with TLE. Diffusion tensor imaging (DTI) is a novel imaging technique that provides insight into the structural integrity of cerebral white matter. DTI studies have demonstrated extensive bilateral white matter abnormalities in TLE that extend far beyond the temporal lobe, even in patients with unilateral MTS. The relationship between white matter abnormalities, seizures, and comorbidity in TLE remains unclear.

of the discussion about death, health and sickness statistics, there is little recognition of the significance of environmental factors and the manner in which these may influence morbidity and mortality patterns. The cursory manner in which migration statistics have been dealt with has already been alluded to but a similar comment can be made about the coverage of the immensely important topic of population estimation and projection. However, to somebody who hails from Belfast, the most irritating feature of all is the almost complete exclusion of the population data sources for Northern Ireland, apart from a brief reference to birth registrations and notifications of communicable disease. True Northern Ireland is not particularly significant in terms of its proportion of the UK population; nor are its population statistics always as rich as those for Great Britain or as readily available. But it does have its own registrar general who publishes weekly, quarterly and annual returns of births, deaths and marriages and who is responsible for the population census. Moreover, the province has its own Continuous
Psychologische Flexibilität messen: Der Fragebogen zu Akzeptanz und Handeln II

2, 5, 7 des Fragebogens). Es geht also nicht nur um die «Akzeptanz» von seelischen Belastungen, sondern auch um die Fahigkeit, trotz dieser und mit diesen Belastungen flexibel «handeln» zu konnen. Nach Kashdan und Rottenberg [2010] beschreibt PF einen spezifischen Aspekt seelischer Gesundheit, den andere, gut untersuchte Konstrukte wie Symptomfreiheit oder psychologisches Wohlbefinden nicht abdecken. Damit ist das Konstrukt von allgemeiner Bedeutung und nicht nur im Kontext der ACT-Theorie relevant. Eine fur die Psychotherapietheorie der ACT wichtige Annahme bezieht sich darauf, dass PF einen Mediator fur die Veranderung (oder Bewaltigung) psychopathologischer Symptome darstellt. Die Steigerung der PF ware damit der Symptomreduktion vorgeordnet. Weil es bei PF um Verhalten in Situationen geht, ist das Merkmal eigentlich verhaltensdiagnostisch zu erfassen. Um PF einfach und okonomisch erheben zu konnen, gibt es Versuche, das Merkmal auch mittels Fragebogen zu operationalisieren. Der Acceptance and Action Questionnaire I (AAQ-I) [Hayes et al., 2004] ist ein (je nach Version) 9oder 16-ItemFragebogen mit 7-stufigen Aussagen, die indikativ fur PF sein sollen. Inzwischen wurde eine neue Version entwickelt, um insbesondere die interne Konsistenz zu steigern. Der AAQ-II [Bond et al., 2011] umfasst lediglich 7 siebenfach gestufte Items, die aufzusummieren sind. Der Wertebereich liegt damit zwischen 7 und 49, wobei hohere Werte hohere Inflexibilitat kennzeichnen. Die deutsche Version des AAQ-II, der Fragebogen fur Akzeptanz und Handeln II (FAH-II), wurde im Rahmen einer Ubersetzungs-Ruckubersetzungsprozedur erstellt [Gloster et al., 2011a]. Der Fragebogen ist sehr gut handhabbar, die Bearbeitungszeit liegt bei wenigen Minuten. Inzwischen liegen Daten und Referenzwerte von mehreren klinischen (Panik-Patienten, Sozialphobie-Patienten) und Gelegenheitsstichproben (Studenten, Arbeitslose) mit mehr als 1100 Probanden vor.

Expelling policies for shared memory fast packet switches with variable size packets of multiple priority

In this paper we study the efficient design of buffer management policies for QOS efficient shared memory based fast packet switches. There are two aspects that are of interest. First is the packet size: whether all packets have same or different sizes. Second aspect is the value or space priority of the packets, do all packets have the same space priority or different packets have different space priorities. We present two types of policies to achieve QOS goals for packets with different priorities: the push out scheme and the expelling scheme. For this paper we consider the case of packets of variable length with two space priorities and our goal is to minimize the total weighted packet loss. Simulation studies show that, expelling policies can outperform the push out policies when it comes to offering variable QOS for packets of two different priorities and expelling policies also help improve the amount of admissible load. Some other comparisons of push out and expelling policies are also presented using simulations.
Microevolution of Mycobacterium tuberculosis in a Tuberculosis Patient

ABSTRACT Five Mycobacterium tuberculosis isolates were obtained from three body sites from a Dutch patient. The isolates displayed a single genotype by 24-locus MIRU-VNTR typing (except for a single locus not amplified from one isolate) but were differentiated by small variations in IS6110 fingerprints, spoligotypes, 6 hypervariable MIRU-VNTR loci, and/or DiversiLab profiles, revealing patterns of microevolution in a clonal infection.
Why the early Universe preferred the non-supersymmetric vacuum: part II

It was recently shown in [1] that in the context of the ISS models with a metastable supersymmetry breaking vacuum, thermal effects generically drive the Universe to the metastable vacuum even if it began after inflation in the supersymmetry-preserving one. We continue this programme and specifically take into account two new effects. First is the effect of the mass-gap of the gauge degrees of freedom in the confining supersymmetry preserving vacua, and second, is the effect of the back reaction of the MSSM sector on the SUSY breaking ISS sector. It is shown that, even though the mass-gap is parametrically smaller than the , vevs, it drastically reduces the temperature required for the Universe to be driven to the metastable vacuum: essentially any temperature larger than the supersymmetry breaking scale ? is sufficient. On the other hand we also find that any reasonable transmission of SUSY breaking to the MSSM sector has no effect on the vacuum transitions to, and the stability of the SUSY breaking vacuum. We conclude that for these models the early Universe does end up in the SUSY breaking vacuum.
