Factors affecting transposition of the Himar1 mariner transposon in vitro.

Mariner family transposable elements are widespread in animals, but their regulation is poorly understood, partly because only two are known to be functional. These are particular copies of the Dmmar1 element from Drosophila mauritiana, for example, Mos1, and the consensus sequence of the Himar1 element from the horn fly, Haematobia irritans. An in vitro transposition system was refined to investigate several parameters that influence the transposition of Himar1. Transposition products accumulated linearly over a period of 6 hr. Transposition frequency increased with temperature and was dependent on Mg2+ concentration. Transposition frequency peaked over a narrow range of transposase concentration. The decline at higher concentrations, a phenomenon observed in vivo with Mos1, supports the suggestion that mariners may be regulated in part by "overproduction inhibition. " Transposition frequency decreased exponentially with increasing transposon size and was affected by the sequence of the flanking DNA of the donor site. A noticeable bias in target site usage suggests a preference for insertion into bent or bendable DNA sequences rather than any specific nucleotide sequences beyond the TA target site.
Room‐Temperature Ferromagnetism in ZnO‐Encapsulated 1.9 nm FePt3 Nanoparticle–Composite Thin Films with Giant Interfacial Anisotropy

As synthesized 1.9-nm FePt3 nanoparticles are superparamagnetic at room temperature. Coating those nanoparticles with ZnO renders them permanently ferromagnetic with coercivity field of 650 Oe at room temperature. First-principles calculations indicate that giant interfacial anisotropy, induced by the strong spin-orbit interaction of enhanced orbit momentum of Fe, overcomes the superparamagnetic limit, leading to exceptional room-temperature permanent ferromagnetism. The findings are important for the understanding of the origin of permanent ferromagnetism at ultrasmall size and critical for ultrahigh density recording and information processing.
Effect of trust and risk on purchase intentions in online secondary ticketing : sport consumers and ticket reselling

The current research focused on examining how perceived risk and trust are related to consumers’ purchase intentions within the online secondary ticket marketplace. Furthermore, this study attempted to identify the relationship between perceived risk and trust associated with online secondary ticketing. The Structural Equation Modelling (SEM) method with a convenience sample of 302 participants was employed to analyse the conceptual framework and psychometric property of the scale. The results indicate that trust significantly and negatively influenced perceived risk and trust exerts a significant impact on consumers’ purchase intentions of online secondary tickets. Consumers’ perceived risk had a direct negative effect on consumers’ online purchase intentions of secondary ticketing. However, the findings of the current study showed that the impact does not reach a significant level. These results and future implications for practical and theoretical research are also discussed.

Mistreatment of Women in Childbirth: Time for Action on This Important Dimension of Violence against Women

The mistreatment of women in childbirth has been documented by researchers for over three decades in all global regions. The scale of the problem is indicated by a systematic review conducted by Meghan Bohren and colleagues which provides a foundation from which a typology of violence can be developed and used as a basis for developing measurement instruments and tools. This is a valuable complement to other work that is currently underway in this area. A multicountry study on the mistreatment of women during childbirth could be extremely valuable in generating comparable information on prevalence risk groups and facilities and the health consequences (physical and mental including future health-seeking practices and expectations). It would provide the foundation needed for developing health policy monitoring its impact and advocating for proper resources. (Excerpt)
Managing performance requirements for information systems

A major challenge,for injbrmation system development is to deal with performance requirements, an important class ofnonfunctional requirements (quality attributes, or NFRs). For example, a system should “authorise credit card sales quickly. ” Howevev, pe@rmancerequirements, like other NFRs (such as accuracy and security). are d$icult to handle, since they haveglobal impact on systems, and can co$ict with each other and with target alternatives. This paper overviews a “Performance Requirements Framework ” (PeRF). intended to help developers “build performance into ” information systems, by producing customised solutions for the particular characteristics of a system, drawing on knowledge of pe@rmance and development. PeRF incorporates an existing goal-oriented and qualitative framework, the “NFR Framework,” which oj$ers a sy~ytematic process for treating NFRs. PeRF’s catalogues represent and organise knowledge of irzformation systems, their design, implementation andperformance. Catalogues, available in a partial developer’s tool, draw on experience in implementing objected-basedsemantic data models, as well as Softiare Perftirmance Engineering (SPE) principles. PeRF was used in empirical studies of injtirmation systems to address a variev ofper,fi,rmance requirements, domains, characteristics and tradeo$s.
The Use of Humor in Promoting Positive Provider-Patient Interactions in a Hospital Rehabilitation Unit

Humor within the health care setting apparently can serve to facilitate positive patient-provider interactions and to create a patient-centered environment. This article provides an ethnographic account of patient-provider interactions held during therapeutic activity sessions within a hospital unit (MIRTH) designed to promote therapeutic humor. This study's findings suggest that humor in these activity sessions was mainly a by-product of more predominant effects, such as patients' positive attitude and happiness. Whereas MIRTH used contrived humor to portray its identity as a humor unit, staff and patients also took advantage of spontaneous humor that emerged out of interactions. Humor appeared secondary to the primary outcome of promoting patients' happiness and well being.
Working Together at Mat Time: Politics of Participation.

Learning as part of a group on the mat is a common experience in children’s early education and socialisation. Indeed, many classrooms world have a mat, to which the children are called in addition to chairs and tables (Poveda, 2001). Nonetheless, very little research exists about activity using the mat in junior classrooms either locally or internationally, particularly in relation to children’s perspectives. This paper reports recent findings from a doctoral study that investigated children’s experiences of working together on the mat in three year-two classrooms. Data were gathered through video-observations of teacher-facilitated activity on the mat and semi-structured interviews with children and teachers. The findings suggested that participation on the mat was affected by children’s relationships with each other. Specifically, social dynamics within the children’s peer group appeared to enable or block active participation for particular individuals. Teachers utilised inclusive strategies to ameliorate the affect of the peer group and to enhance participation for children who struggled to secure an active role.
An evaluation of brainstem death documentation: the importance of full documentation

Background : With the introduction of the concept of brainstem death as acceptable proof that life has ended, rather than cessation of the beating heart, the process of determining brain death has to be rigorous to ensure maintenance of confidence in the definition. A recent study from South Thames in the UK revealed that only 44% of brainstem death documentation was complete at the time of referral to the transplant coordinator. The aim of our study was to see whether our documentation of brainstem death in paediatric practice complied with the UK Royal College's guidelines and to determine whether any changes are required to be instituted.
Updating collection representations for federated search

To facilitate the search for relevant information across a setof online distributed collections, a federated information retrieval system typically represents each collection, centrally, by a set of vocabularies or sampled documents. Accurate retrieval is therefore related to how precise each representation reflects the underlying content stored in that collection. As collections evolve over time, collection representations should also be updated to reflect any change, however, a current solution has not yet been proposed. In this study we examine both the implications of out-of-date representation sets on retrieval accuracy, as well as proposing three different policies for managing necessary updates. Each policyis evaluated on a testbed of forty-four dynamic collections over an eight-week period. Our findings show that out-of-date representations significantly degrade performance overtime, however, adopting a suitable update policy can minimise this problem.
X-ray emission from the young brown dwarfs of the Taurus Molecular Cloud

AIMS. We report the X-ray properties of young (~3 Myr) bona fide brown dwarfs (BDs) of the Taurus Molecular Cloud (TMC). METHODS. The XMM-Newton Extended Survey of the TMC (XEST) is a large program designed to systematically investigate the X-ray properties of young stellar/substellar objects in the TMC. In particular, the area surveyed by 15 XMM-Newton pointings (of which three are archival observations), supplemented with one archival Chandra observation, allows us to study 17 BDs with M spectral types. RESULTS. Half of this sample (9 out of 17 BDs) is detected; 7 BDs are detected here for the first time in X-rays. We observed a flare from one BD. We confirm several previous findings on BD X-ray activity: a log-log relation between X-ray and bolometric luminosity for stars (with L*<10 Lsun) and BDs detected in X-rays, which is consistent with a mean X-ray fractional luminosity =-3.5±0.4; for the XEST BDs, the median of log(Lx/L*) (including upper limits) is -4.0; a shallow log-log relation between X-ray fractional luminosity and mass; a log-log relation between X-ray fractional luminosity and effective temperature; a log-log relation between X-ray surface flux and effective temperature. We find no significant log-log correlation between the X-ray fractional luminosity and EW(Halpha). Accreting and nonaccreting BDs have a similar X-ray fractional luminosity. The median X-ray fractional luminosity of nonaccreting BDs is about 4 times lower than the mean saturation value for rapidly rotating low-mass field stars. Our TMC BDs have higher X-ray fractional luminosity than BDs in the Chandra Orion Ultradeep Project. CONCLUSIONS. The X-ray fractional luminosity declines from low-mass stars to M-type BDs, and as a sample, the BDs are less efficient X-ray emitters than low-mass stars. We thus conclude that while the BD atmospheres observed here are mostly warm enough to sustain coronal activity, a trend is seen that may indicate its gradual decline due to the drop in photospheric ionization degree.
The colour–magnitude relation for galaxies in the Coma cluster

We present a new photometric catalogue of the Coma galaxy cluster in the Johnson U and V bands. We cover an area of 3360 arcmin2 of sky, to a depth of in a 13-arcsec diameter aperture, and produce magnitudes for ∼1400 extended objects in metric apertures from 8.8- to 26-arcsec diameters. The mean internal rms scatter in the photometry is 0.014 mag in V, and 0.026 mag in U, for . We place new limits on the levels of scatter in the colour–magnitude relation (CMR) in the Coma cluster, and investigate how the slope and scatter of the CMR depend on galaxy morphology, luminosity and position within the cluster. As expected, the lowest levels of scatter are found in the elliptical galaxies, while the late-type galaxies have the highest numbers of galaxies bluewards of the CMR. We investigate whether the slope of the CMR is an artefact of colour gradients within galaxies, and show that it persists when the colours are measured within a diameter that scales with galaxy size. Looking at the environmental dependence of the CMR, we find a trend of systematically bluer galaxy colours with increasing projected radius from the centre of the cluster. Surprisingly, this is accompanied by a decreased scatter of the CMR. We investigate whether this gradient could be caused by dust in the cluster potential, however the reddening required would produce too large a scatter in the colours of the central galaxies. The gradient appears to be better reproduced by a gradient in the mean galactic ages with projected radius.
Bilateral Electrodermal Habituation‐Dishabituation and Resting EEG in Remitted Schizophrenics

This study examined bilateral electrodermal responding, heart rate, and resting EEG in schizophrenics who were not psychotic at the time of testing. Twenty-four carefully diagnosed, remitted schizophrenics were compared to 22 medical outpatient controls. Subjects were exposed to 17 pure tones; the 16th tone differed in frequency and duration from the others. Prior to the tone series, subjects engaged in 2 minutes of respiratory maneuvers followed by a 5-minute rest period during which EEG was recorded. Consistent with past reports examining chronic, hospitalized patients, the schizophrenics divided evenly into responding and nonresponding groups and skin conductance responding was associated with a higher rate of spontaneous activity, elevated tonic conductance levels, and more responding during the respiratory exercises. When those responding in the control and schizophrenic groups were compared for number and amplitude of tone-elicited responses, no group differences emerged. There were no differences in dishabituation between these two groups. A variety of analyses failed to reveal any evidence of electrodermal or cerebral asymmetry. There were no differences between the two schizophrenic groups in measures of heart rate or resting EEG. However, consistent with other reports using hospitalized patients, the schizophrenics as a group produced less EEG alpha and more delta than the normal subjects. These results are consistent with the hypothesis that the electrodermal and EEG phenomena identified in psychotic, hospitalized patients represent stable traits characteristic of schizophrenia.
Relationship of attachment to abuse in incarcerated women

Relationship of Attachment to Abuse in Incarcerated Women. (August 2004) Brandon Lee Davis, B.A., Buena Vista University; M.A., Truman State University Chair of Advisory Committee: Dr. Michael Duffy Four adult attachment styles that have been extensively reported in the literature have been labeled secure, dismissing, preoccupied, and fearful. Unfortunately, there are no existing published studies that measure attachment styles of incarcerated women. This study used responses from 158 women incarcerated at a federal prison on the Relationship Questionnaire, Millon Clinical Multiaxial Inventory-III (MCMI-III), and Record of Maltreatment Experiences to examine several facets of the association of attachment styles with childhood abuse and scales on the MCMI-III. The inmates who survived abuse endorsed the fearful and preoccupied attachment styles more, and the secure style less, than did the women who did not acknowledge a history of abuse. There was no statistically significant finding among attachment styles based on physical or sexual abuse. Inmates who were abused by a family member were more likely to endorse the fearful attachment style. The depressive, sadistic, and dependent MCMI-III scales were determined to be more highly associated with fearful or preoccupied attachment styles than with dismissing or secure styles. Finally, the inmates endorsed the anxious/ambivalent (fearful and preoccupied) attachment style more, and the secure style less, than non-incarcerated individuals as reported in the literature.
The anti-oxidant defence response in individuals with the indeterminate form of Chagas disease (American trypanosomiasis)

Abstract In previous studies in animal models, Trypanosoma cruzi-induced oxidative stress and damage have sometimes been controlled by the host's anti-oxidant defence responses. The role of the anti-oxidant defence responses, such as the activities of the anti-oxidant enzymes glutathione peroxidase (GPx) and superoxide dismutase (SOD), in protection against inflammation and damage have now been investigated in humans infected with T. cruzi. The subjects were 32 asymptomatic but seropositive individuals with the indeterminate form of Chagas disease, 18 symptomatic and seropositive patients with the chronic disease, and 50 seronegative and apparently healthy controls. The inflammatory process was explored using serum concentrations of tumour necrosis factor (TNF) and NO. The serum concentrations of GPx in the patients in the indeterminate phase of infection were similar to those in the controls but much higher than those in the chronic cases (P=0.001). The serum concentrations of SOD in the patients in the indeterminate phase of infection were not only significantly higher than those in the cases of chronic Chagas disease (P=0.0004) but also significantly higher than those in the controls (P<0.001). The seropositive subjects had significantly higher serum concentrations of TNF and NO than the controls (P<0.01 for each) and the cases of chronic Chagas disease had significantly higher serum concentrations of TNF and NO than the subjects with the indeterminate form of the disease (P<0.01 for each). It therefore appears that the host's anti-oxidant defence responses (at least in terms of elevated concentrations of SOD) may inhibit inflammation during the indeterminate phase of Chagas disease.
Assessment of asymptomatic coronary artery disease in apparently uncomplicated type 2 diabetic patients: a role for lipoprotein(a) and apolipoprotein(a) polymorphism.

OBJECTIVE In patients with uncomplicated diabetes, there is low probability of finding significant coronary artery disease (CAD) by noninvasive tests. Therefore, screening for its presence is not justified, and it is important to find reliable predictors of silent CAD to identify patients with uncomplicated diabetes for further screening. The relationship between lipoprotein(a) [Lp(a)], apolipoprotein(a) [apo(a)] polymorphism, and silent CAD has never been studied. We investigated the association of Lp(a) and apo(a) polymorphism with angiographically documented asymptomatic CAD in type 2 diabetic patients without evident complications. RESEARCH DESIGN AND METHODS A total of 1,323 diabetic patients without any clinical and electrocardiographic evidence of CAD were evaluated. Of 121 patients with highly positive results of exercise electrocardiography (ECG) (n = 30) or positive results on exercise thallium scintigraphy (n = 91), 103 subjects showed angiographically documented CAD (CAD group). Of 1,106 patients with negative results on exercise ECG, 103 subjects without CAD (NO CAD group) were selected and matched by age, gender, and duration of diabetes to patients in the CAD group. In patients in the NO CAD group, results of exercise ECG, 48-h ambulatory ECG, and stress echocardiography were negative for CAD. RESULTS The CAD group had higher Lp(a) levels (21.7 +/- 17.7 vs. 15.2 +/- 19.0 mg/dl; P = 0.0093) than the NO CAD group, and a percentage of subjects had at least one small apo(a) isoform (68.9 vs. 29.1%; P = 0.0000) higher than the NO CAD group. Logistic regression analysis showed that apo(a) phenotypes (odds ratio [OR] 8.13, 95% CI 3.65-21.23), microalbuminuria (5.38, 2.44-11.88), smoking (2.72, 1.31-5.64), and Lp(a) levels (2.41, 1.15-5.03) were predictors of asymptomatic CAD. CONCLUSIONS Our investigation reports the first evidence of an independent association of Lp(a) and apo(a) polymorphism with asymptomatic CAD. This suggests that Lp(a) levels and apo(a) phenotypes could be used together with other risk factors as markers of asymptomatic CAD in patients with diabetes.
Developing a regional drought climatology for the Czech Republic

This study presents a methodology for the analysis of a drought climatology within a particular region that enables a user to define drought areas at a high spatial resolution. It is suitable for quantifying the relative differences in the intensity of drought spells, and the frequency and duration between individual stations within an area of interest. The methodology is based on the Standardized Precipitation Index (SPI), the Palmer Drought Severity Index (PDSI) and the Palmer Z‐index (Z‐index). However, the climatological parameters needed to process and calculate the indices were not derived separately for each site as is usually done, but were based on a set of all available weather stations in the studied region. This approach was utilized in the case study including all of the Czech Republic using 233 climatological stations with monthly records of mean temperature and precipitation for the period 1961–2000. The study is also focussed on the development of more efficient ways of communicating results to the stakeholders. Therefore, a method allowing for an integration of several drought indices into a single indicator called the Integrated Climatological Drought Indicator (ICDI) was developed. The newly developed method allowed for an objective identification of the drought‐prone regions of the country that were defined as areas with a chance (higher than 50 and 60% respectively) of moderate or extreme drought. We have found that 12.3 and 3% of the country area, respectively, belong within these categories and that these regions also happen to be prime agricultural areas. The conclusions were supported by the results of a cluster analysis. Finally, the analysis of time trends was conducted, which showed that the majority of 233 stations had grown significantly drier during the studied period. The main driving force behind this development was found to be an increase of temperature, especially in the 1990s. Copyright © 2008 Royal Meteorological Society
On the spectrum of waveguides in planar photonic bandgap structures

We study a Helmholtz-type spectral problem related to the propagation of electromagnetic waves in photonic crystal waveguides. The waveguide is created by introducing a linear defect into a two-dimensional periodic medium; the defect is infinitely extended and aligned with one of the coordinate axes. This perturbation introduces guided mode spectrum inside the band gaps of the fully periodic, unperturbed spectral problem. In the first part of the paper, we prove that guided mode spectrum can be created by arbitrarily ‘small’ perturbations. Secondly, we show that, after performing a Floquet decomposition in the axial direction of the waveguide, for any fixed value of the quasi-momentum kx, the perturbation generates at most finitely many new eigenvalues inside the gap.
