Making sense of reflection: a comparison of beginning and experienced teachers’ perceptions of reflection for practice

The importance of reflection for learning has been emphasised in professional education programmes. In teacher education, a number of researchers have claimed the success of various initiatives in developing teachers as reflective practitioners. However, there appear to be few studies comparing and contrasting beginning and experienced teachers’ perceptions of the usefulness of reflection for practice. The study reported here examined how reflection was used by experienced and beginning teachers who were formally introduced to the same model of reflection. The data were collected as part of two separate qualitative studies, one a study of 12 beginning teachers and one of 12 experienced teachers, via semi‐structured interviews. The findings suggested that both groups of teachers moved from being somewhat sceptical about reflection, to embracing reflection as a tool to analyse and modify their practice. A major difference between the two groups related to the scope, focus and impact of their reflective activities.
Numerical Simulating Nonlinear Effects of Ultrasonic Propagation on High-speed Ultrasonic Gas Flow Measurement

The effects of nonlinear ultrasonic propagation on high-speed ultrasonic gas flow measurement are analyzed based on the sound line equation derived from Snell's geometric acoustic law. A math ematical model for the ultrasonic propagation path in ultrasonic flowmeter pipe is built, and the relationship between x and r is calcula ted by MATLAB programming and ode45 simulating. The ultrasonic propagation path at the flow rate of 3 � 30m/s is simulated in the assumed boundary conditions of the pipeline, transducer installation and fluid state. It shows that the nonlinear propagation characte ristics cause the large deviations of the position of received ultrasonic waves in conditions of different flow rates, which strongly aff ects the stability and accuracy of flow measurement. The simulated offset data of the receiving position are useful for the high-s peed gas ultrasonic flowmeter installation and dry calibration on clamp-on ultrasonic flowmeters.
Highly restricted expression of the thymus leukemia antigens on intestinal epithelial cells

The TL region of the major histocompatibility complex of the mouse contains dozens of tandemly arranged class I genes, including those encoding the thymus leukemia (TL) antigens. TL antigens have been thought to be expressed only on the surface of some T lineage cells, namely immature thymocytes of some mouse strains (TL+ strains), some leukemia cells, and activated T cells. While the function of TL antigens is unknown, recent studies have implicated the products of at least some TL region class I genes as molecules that present antigens to gamma/delta T cells. Since some gamma/delta T cells are known to be specifically associated with certain epithelial tissues, we have investigated the expression of some TL region class I genes in a variety of epithelium-containing tissues. Our results show that the TL antigen gene of C57BL/6 mice, T3b, and the TL antigen genes of BALB/c mice, T3d (previously T3c) and T18d (previously T13c), are highly expressed in the epithelium of the small intestine. In the case of T3b, we further show, using a T3 product-specific antibody, that its product is expressed on the surface of the columnar epithelial cells. In addition, we demonstrated that two other TL region class I genes of C57BL/6 origin, T9b and T21b, are also expressed nearly exclusively in intestinal epithelial cells. These results are consistent with the hypothesis that the products of these TL region class I genes are recognized by gamma/delta T cell receptors of intestinal intraepithelial lymphocytes, a subset of gamma/delta T cells that is localized in the intestinal epithelium and has a restricted V gamma repertoire. Finally, our study indicates that the relative levels of expression of the two homologous TL antigen genes, T3d and T18d, differ widely between the thymus and the intestine.
Analysis of atelectasis, ventilated, and hyperinflated lung during mechanical ventilation by dynamic CT.

STUDY OBJECTIVE To study the dynamics of lung compartments by dynamic CT (dCT) imaging during uninterrupted pressure-controlled ventilation (PCV) and different positive end-expiratory pressure (PEEP) settings in healthy and damaged lungs. DESIGN Experimental animal investigation. SETTING Experimental animal facility of a university department. INTERVENTIONS In seven anesthetized pigs, static inspiratory pressure volume curves were obtained to identify the individual lower inflection point (LIP) before and after saline solution lung lavage. During PCV, PEEP was adjusted 5 millibars (mbar) below the individually determined LIP (LIP - 5), at the LIP, and 5 mbar above the LIP (LIP + 5). MEASUREMENTS AND RESULTS Measurements were repeated before and after induction of lung damage. Hemodynamics, arterial and mixed venous blood gases, and dCT imaging in one juxtadiaphragmatic slice (effective temporal resolution of 100 ms) were assessed during uninterrupted PCV in series of three successive respiratory cycles. The mean fractional area (FA) of the hyperinflated lung (FA-H), mean FA of ventilated lung, mean FA of poorly ventilated lung, and mean FA of nonventilated lung (FA-NV), and the change in FA of the whole lung area (DeltaFA) were compared at different PEEP settings. Calculated pulmonary shunt (Qs/Qt) was compared to FA-NV. LIP + 5 decreased the amount of atelectasis (FA-NV) and increased hyperinflation (FA-H) in healthy and injured lungs. Cyclic changes of atelectasis (DeltaFA-NV) and hyperinflation (DeltaFA-H) were observed in both healthy and injured lungs. In the injured but not in the healthy lungs, the amount of cyclic changes of atelectasis and hyperinflation were independent from the adjusted PEEP level. FA-NV correlated with the calculated Qs/Qt, with a slight overestimation (mean +/- SEM, 2.1 +/- 4.1%). CONCLUSIONS dCT imaging allows the following: (1) the quantification of the extent of atelectasis, ventilated, poorly ventilated, and hyperinflated lung parenchyma during ongoing mechanical ventilation; (2) the detection and quantification of repeated recruitment and derecruitment, as well as hyperinflation; and (3) an estimation of Qs/Qt. dCT adds promising functional information for the respiratory treatment of early ARDS.
”Generalizability” as Recognition: Reflections on a Foundational Problem in Qualitative Research

The aim of the article is to develop what counts as “generalizability” in qualitative research. By taking an ontological and epistemic stance in relation to the four foundational problems: 1)Knowledge and its various forms. 2) Properties of reality and the doubleness of the situation. 3) How is understanding possible? 4) The researcher’s role: What are the fundamental questions that the researcher must ask himself before a study is designed? we are able to approach the exploration of ”generalizability” in qualitative research. Methodological theorists agree that the question of applicability is essential in the discussion of “generalizability” in qualitative research. If the quantitative tradition’s requirement for replicability also has to be met, the pressing question during the article is what counts as replicability and applicability in qualitative research. In the exploration of what is involved in “generalizability” in qualitative research a combination of Gadamer and Flyvbjerg´s thinking are important sources for a reflection on the ontological and epistemic questions related to the four foundational problems. The ontological question of what establishes a situation is an essential interpretation for the finding. A situation is characterised by its quality of doubleness: it is unique and typical at the same time. People with each their unique story and life world constitute the uniqueness of the situation. And a situation is typical in the sense that fundamental experiences can be found in every situation. The typical is what we as people have in common. There will be typical traits and recogizable patterns in every situation. The finding show us that “generalizability” in qualitative research builds on recognisability and a challenge to practice as a practical reasoning.
Institutions and Media Use in Democratizing Countries: The Czech-Slovak Case as a Quasi-Experiment

Using original survey data from the early democratization period in Central and Eastern Europe, I compare the choice of media for individuals’ informational demands in the context of differently evolved media environments. Using the quasi-experimental setting of the Czech Republic and Slovakia, the findings indicate that individuals who express more interest in staying informed about politics are more likely to use public rather than privatizing media. Further, in the context of the multilevel design, this media preference is consistent regardless of the differing extents of privatization between the countries. This analysis adds empirical evidence to the ongoing debate on the role of mass media and the process of political socialization in democratizing countries.
Current Ripple Damping Control to Minimize Impedance Network for Single-Phase Quasi-Z Source Inverter System

The single-phase quasi-Z source inverter (qZSI) topology has recently attracted attention for single-phase grid-tie photovoltaic (PV) applications. However, due to the inherent second-harmonic power flow in single-phase systems, a large qZS network is required to reduce the second-harmonic component of currents and voltages on the dc side. Minimization of the qZS network remains an open issue. This paper proposes a technique that minimizes the qZS capacitance and inductance of the single-phase qZSI topology by employing dc-side low-frequency current ripple damping control. Through analysis of power flow, a second-harmonic power model is derived and the ripple power is analyzed for minimization of the qZS network. A current ripple damping control is proposed to ensure suppression of second-harmonic power flow through the inductors. Simulation and experimental results verify the theoretical analysis, damping control, and the proposed design minimization of the qZS network for the single-phase topology.
Neural substrates of context‐ and person‐dependent altruistic punishment

Human altruistic behaviors are heterogeneous across both contexts and people, whereas the neural signatures underlying the heterogeneity remain to be elucidated. To address this issue, we examined the neural signatures underlying the context‐ and person‐dependent altruistic punishment, conjoining event‐related fMRI with both task‐based and resting‐state functional connectivity (RSFC). Acting as an impartial third party, participants decided how to punish norm violators either alone or in the presence of putative others. We found that the presence of others decreased altruistic punishment due to diffusion of responsibility. Those behavioral effects paralleled altered neural responses in the dorsal anterior cingulate cortex (dACC) and putamen. Further, we identified modulation of responsibility diffusion on task‐based functional connectivity of dACC with the brain regions implicated in reward processing (i.e., posterior cingulate cortex and amygdala/orbital frontal cortex). Finally, the RSFC results revealed that (i) increased intrinsic connectivity strengths of the putamen with temporoparietal junction and dorsolateral PFC were associated with attenuated responsibility diffusion in altruistic punishment and (ii) increased putamen‐dorsomedial PFC connectivity strengths were associated with reduced responsibility diffusion in self‐reported responsibility. Taken together, our findings elucidate the context‐ and person‐dependent altruistic behaviors as well as associated neural substrates and thus provide a potential neurocognitive mechanism of heterogeneous human altruistic behaviors.

Role of Infections in the Manifestation or Reactivation of Inflammatory Bowel Diseases

The etiology of inflammatory bowel disease (IBD) is unknown. In addition to genetic and environmental factors, microorganisms have been discussed as possibly playing an important role. Recent reports in the literature do not suggest that a specific persistent infection causes IBD, but indicate that enteric pathogens could cause initial onset of IBD and are associated with reactivation of quiescent disease. Despite their self-limited character, these infections initiate a cascade of inflammatory events leading to chronic, relapsing disease in a genetically susceptible host (“hit-and-run” hypothesis). Epidemiological and microbiologic studies suggest that enteropathogenic microorganisms play a substantial role in the clinical initiation and relapses of IBD. However, similar to traveler's diarrhea, the frequency of infections in the first manifestation and in relapses of IBD is probably understated, due to the problems in detecting enteric pathogens. Thus microbiologic screening is helpful in patients with flares of IBD for optimal medical treatment.
Criminal Investigations in Child Protective Services Cases

This study analyzed the frequency and correlates of criminal investigation of child maltreatment in cases investigated by child protective service (CPS), using national probability data from the National Survey of Child and Adolescent Well-Being. Criminal investigations were conducted in slightly more than 25% of cases. Communities varied substantially in percentage criminally investigated. Sexual abuse was the most frequent type of maltreatment criminally investigated followed by physical abuse. Logistic regression results indicated that criminal investigations were more likely when caseworkers perceived greater harm and more evidence; when CPS conducted an investigation rather than an assessment; when a parent or a legal guardian reported the maltreatment; and when cases were located in communities in which CPS and police had a memorandum of understanding (MOU) governing coordination. Most variation between communities in criminal investigation remained unexplained. The findings suggest the potential of MOUs for communities wanting to increase criminal investigation.
Comparative Study of Outcomes between Shunting after Cranioplasty and in Cranioplasty after Shunting in Large Concave Flaccid Cranial Defect with Hydrocephalus.

OBJECTIVE The cranioplasty and ventriculoperitoneal (VP) shunt operation have been used to treat a large cranial defect with posttraumatic hydrocephalus (PTH). The aim of this study was to evlauate the difference of outcomes between in the shunting after the cranioplasty (group 1) and the cranioplasty after the shunting (group 2) in a large flaccid cranial defect with PTH. METHODS In this study, a retrospective review was done on 23 patients undergoing the cranioplasty and VP shunt operation after the decompressive craniectomy for a refractory intracranial hypertension from 2002 to 2005. All of 23 cases had a large flaccid concave cranial defect and PTH. Ten cases belong to group 1 and 13 cases to group 2. The outcomes after operations were compared in two groups 6 months later. RESULTS The improvement of Glasgow outcome scale (GOS) was seen in 8 cases (80.0%) of total 10 cases in group 1, and 6 cases (46.2%) of 13 cases in group 2. Three (75.0%) of 4 cases with hemiparesis in group 1 and 3 of 6 cases (50.0%) in group 2 were improved. All cases (2 cases) with decrease of visual acuity were improved in each group. Dysphasia was improved in 3 of 5 cases (60%) in group 1 and 4 of 6 cases (66.6%) in group 2. CONCLUSION These results suggest that outcomes in group 1 may be better than in group 2 for a large flaccid concave cranial defect with PTH.
Ascending and Descending Melodic Intervals: Statistical Findings and Their Perceptual Relevance

Evidence is reported for the existence and the perceptual relevance of a hitherto rather unattended regularity of melodic patterns in Western music. An inquiry into the occurrence of within-octave melodic intervals in a large variety of examples of Western music showed small intervals to be predominantly descenders and large ones to be ascenders. The perceptual relevance of the distributional regularity in question was tested. Subjects were required to discriminate between computer-generated melodic patterns that were endowed either with the discovered regularity of shape distribution over intervals or with the reversed structure. The results were convincingly positive. Music-theoretical intuitions of Meyer (1956, 1973) are used to account for the data and to claim their generalizability to non-Western melodic patterns. Finally, the outcome of this study is discussed with respect to its relevance to various musicological and music-psychological issues.

Women Taking Positions Within Computer Science

In this study the authors argue that women situated within a masculine domain like computing can be seen as taking various positions within that domain rather than a position based on a gender-specific pattern. The authors' work is based on a conventional computer science course and students' experiences in a specific unit taken in year one. Through a deconstruction of aspects of this course, the authors analyse the subject positions of some of the women involved and show that the commonality in their relationship to computing is based upon a standpoint grounded in their complex positioning as both insiders and outsiders in that domain. This standpoint enables them to engage with 'the rules' in various ways. A woman tutor takes a position committed to providing access to students by attempting to integrate practice and abstraction, and the women students develop alternatives to the given rules, i.e. approaches to programming which work for them.
The Presumption of Innocence in the Trial Setting

The starting frame with which jurors begin trials and the approach which they should take toward the presentation of evidence by the prosecution and defense are distinguished. A robust interpretation of the starting frame, according to which jurors should begin trials by presuming the material innocence of defendants, is defended. Alternative starting frames which are less defendant‐friendly are shown to cohere less well with the notion that criminal trials should constitute stern tests of the government's case against those it has charged with crimes. The intuitive case for the robust presumption of innocence is supplemented with empirical evidence concerning the psychology of belief formation and preservation. Various objections to the proposed starting frame are addressed.
Instrumental and vocal teaching: how do music students learn to teach?

A survey of final-year music students at the University of York for the Investigating Musical Performance research project found that 45% (23 of the 51 students in the year group) regularly gave instrumental or vocal lessons. Semi-structured interviews with 16 students revealed a range of teaching activities including workshop leading, one-to-one lessons and group teaching. This paper examines the attitudes of the nine students engaged in giving instrumental lessons and explores their development as teachers and their understanding of some of the key concepts of teaching and learning. Findings suggest that students learned to teach through increased experience rather than formal training, and although they were enthusiastic, reporting benefits to their own learning and performing, they could have been more pro-active regarding their development as teachers and more resourceful in their approaches towards lesson content and materials, strategies relating to modelling and motivation and the teaching of practice techniques. Increased provision of support and training opportunities could be made by Higher Education institutions, by giving students feedback regarding their effectiveness as teachers, opportunities to discuss their teaching, and enabling learning through mentoring partnerships with more experienced teachers.
Occupational Risk Factors for Brain Cancer in Canada

Objective: We sought to examine the impact of occupational exposure on brain cancer risk. Methods: Mailed questionnaires were used to collect information on lifetime employment history, occupational exposure to 18 chemicals, and other risk factors for 1009 incident cases of brain cancer and 5039 control subjects in Canada in 1994 to 1997. Results: People exposed to asphalt and welding had respective odds ratio (and 95% confidence interval) of 1.29 (1.02–1.62) and 1.26 (0.98–1.45). An increased risk of brain cancer might be associated with exposure to asbestos, benzene, mineral or lubricating oil, isopropyl oil, and wood dust and with following occupations: teaching; protective service; metal processing and related jobs, and metal shaping and forming; knitting in textile processing; construction trades; and transport equipment operating. Conclusions: Our study suggests a possible role for occupational exposure in the etiology of brain cancer.
Throughput Improvement and Its Tradeoff with The Queuing Delay in the Diamond Relay Networks

Diamond relay network model, as a basic transmission model, has recently been attracting considerable attention in wireless ad hoc networks. Node cooperation and opportunistic scheduling scheme are two important techniques to improve the performance in wireless scenarios. In the paper we consider such a problem how to efficiently combine opportunistic scheduling and cooperative modes for the Rayleigh fading scenario in the diamond relay network. To do so, we first compare the throughput of SRP (Spatial Reused Pattern) and AFP (Amplify Forwarding Pattern) in the half-duplex case with the assumption that channel side information is known to all and then come up with a new scheduling scheme. It will be verified that only switching between SRP and AFP simply does little help to obtain an expected improvement because SRP is always superior to AFP on average due to its efficient spatial reuse. To improve the throughput further, we put forward a new processing strategy in which buffers are employed at both relays in SRP mode. By efficiently utilizing the links with relatively higher gains, the throughput can be greatly improved at a cost of queuing delay. Furthermore, we shall quantitatively evaluate the queuing delay and the tradeoff between the throughput and the additional queuing delay. Finally, to realize our developed strategy and make sure it always run at stable status, we present two criteria and an algorithm on the selection and adjustment of the switching thresholds. Copyright © 2009 John Wiley & Sons, Ltd. We put forward a new processing strategy in which buffers are employed at both relays in SRP mode. Theoretical analysis have shown that the throughput can be greatly improved at a cost of queuing delay by using this developed scheme. We also consider the tradeoff between the throughput and the additional queuing delay in theory.
FootPrinter: a program designed for phylogenetic footprinting

Phylogenetic footprinting is a method for the discovery of regulatory elements in a set of homologous regulatory regions, usually collected from multiple species. It does so by identifying the best conserved motifs in those homologous regions. This note describes web software that has been designed specifically for this purpose, making use of the phylogenetic relationships among the homologous sequences in order to make more accurate predictions. The software is called FootPrinter and is available at http://bio.cs. washington.edu/software.html.
