Authors: Kim Insung , Joo Hyeonkyu , Jeong Soonjong , Kim Minsoo , Song Jaesung 
Published: June 2010

AbstractPiezoelectric cantilever was manufactured using the PMN‐PZT thick film for electric harvesting device. In order to find the better properties, the piezoelectric cantilever was manufactured by two forms (bi‐morph and triple‐morph). The generation characteristics were investigated according to the variations of frequency, load resistance and mass weight. The piezoelectric cantilever output voltage increased according to the increase of load resistance and the output power quality was also investigated by changing the load resistance, mass weight and frequency. The bi‐morph piezoelectric cantilever output power which resulted from the conditions of 33 kΩ, 0.25 g, 197 Hz was 230 μW at 2.75VRMS. And then, Average micro power from triple‐morph piezoelectric cantilever was 432 μW, 6.57 VRMS at 154 Hz. This paper presented the possibility of electric harvesting devices with using PMN‐PZT triple‐morph cantilever for remote control and sensor node. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Eulityte glasses – synthesis and characterization
Authors: Berbecaru Ciceron , Alexandru Horia V. , Polosan Silviu 
Published: June 2010

AbstractOxides glasses are suitable for electronic and optoelectronic applications (band gap higher than 3 eV). Eulytite glasses were obtained from Bi4GeO14 sintered powder or mixture oxides powders Bi2O3–GeO2. The powders rapidly heated and melted at 1050 °C for 5 ÷ 10 min was poured on the graphite plates under the glass transition temperature. Structural SEM, XRD and EDX investigations were performed at room temperatures. The frequency dependence of the permittivity and loss (45 Hz ÷ 5 MHz) was investigated on a large temperature range between –140 and +375 °C. The permittivity and loss increase with the temperatures increase and decrease with the frequency increase. An activation energy of 0.88 kcal/mol, comparable to the thermal energy RT = 0.65 kcal/mol, was found for cluster formation on 150 ÷ 200 °C temperature range. The jump of permittivity on the range 275 ÷ 325 °C suggest an incipient glass transition at lower temperatures than 400 °C, as usually is accepted. The permittivity increase, correlated with the dipolar polarization was noticed at higher temperatures. The decrease of permittivity and loss in 10 ÷ 100 kHz frequency range, at the mentioned temperatures, supports this assertion. The estimated relaxation times suggest the big clusters formation.

Efficient evaluation of the accuracy of molecular quantum dynamics on an approximate analytical or interpolated ab initio potential energy surface
Authors: Zimmermann Tomáš , Ruppen Julien , Li Baiqing , Vaníček Jiří 
Published: June 2010

AbstractAb initio electronic structure methods have reached a satisfactory accuracy for the calculation of static properties, but remain too expensive for quantum dynamical calculations. Recently, an efficient semiclassical method was proposed to evaluate the accuracy of quantum dynamics on an approximate potential without having to perform the expensive quantum dynamics on the accurate potential. Here, this method is applied for the first time to evaluate the accuracy of quantum dynamics on an approximate analytical or interpolated potential in comparison to the quantum dynamics on an accurate potential obtained by an ab initio electronic structure method. Specifically, the vibrational dynamics of H2 on a Morse potential is compared with that on the full CI potential, and the photodissociation dynamics of CO2 on a LEPS potential with that on the excited 1Π surface computed at the EOM‐CCSD/aug‐cc‐pVDZ level of theory. Finally, the effect of discretization of a potential energy surface on the quantum dynamics is evaluated. © 2010 Wiley Periodicals, Inc. Int J Quantum Chem 110:2426–2435, 2010
Bmi1 Distinguishes Immature Retinal Progenitor/Stem Cells from the Main Progenitor Cell Population and Is Required for Normal Retinal Development
Authors: Chatoo Wassim , Abdouh Mohamed , Duparc Robert-Hugues , Bernier Gilbert 
Published: June 2010

Abstract
The developing mammalian retina is generated by the proliferation and differentiation of multipotent retinal progenitor cells (RPCs) giving rise to neuronal and glial lineages. Whether an immature progenitor/stem cell subpopulation is present in the developing mammalian retina remains undefined. Deficiency in the polycomb group gene Bmi1 results in reduced proliferation and postnatal depletion of neural and hematopoietic stem cells. Here, we show that Bmi1 is required for the self-renewal of most immature RPCs and for postnatal retinal development. In the embryo, Bmi1 is highly enriched in a rare stage-specific embryonic antigen-1-positive RPC subpopulation expressing the stem cell markers Sox2, Lhx2, and Musashi. Gain-of-function experiments revealed that Bmi1 overexpression could convert RPCs having limited proliferation capacity into RPCs showing extensive proliferation and multiple differentiation capacities over time. At all developmental stages analyzed using the neurosphere assay, Bmi1 deficiency resulted in reduced proliferation and self-renewal of most immature RPCs. Reduced RPCs proliferation was also observed in the peripheral retina of Bmi1−/− fetus and newborn mice. The biological impact of these developmental anomalies was revealed by the reduced retinal diameter of Bmi1-deficient pups. P19Arf and p16Ink4a were upregulated in vivo and in vitro and coinactivation of p53, which lies downstream of p19Arf, partially restored Bmi1-deficient RPCs self-renewal phenotype. Bmi1 thus distinguishes immature RPCs from the main RPC population and is required for normal retinal development.

Published: June 2010

AbstractObjectivesTo assess microstructural and metabolic brain differences between small‐for‐gestational age (SGA) and appropriate‐for‐gestational age (AGA) fetuses at 37 weeks' gestation by magnetic resonance imaging (MRI) spectroscopy and diffusion weighted imaging.MethodsEight SGA and five matched AGA singleton fetuses, all with normal umbilical artery Doppler, were evaluated using MRI at 37 weeks to measure markers of brain microstructure and metabolism. The metabolic spectrum of N‐acetyl‐aspartate/choline, choline/creatine, inositol/choline and creatine/choline ratios in the left frontal lobe and the apparent diffusion coefficient from the right and left basal ganglia and frontal and occipital lobes, pyramidal tract and corpus callosum were analyzed and compared.ResultsAs compared with controls, SGA fetuses showed a significant increase in inositol/choline ratio (SGA, 0.57 vs. AGA, 0.25; P = 0.04) and significantly higher ADC values in the pyramidal tract (SGA, 119.87 × 10−5 mm2/s vs. AGA, 105.11 × 10−5 mm2/s; P = 0.04).ConclusionsSGA fetuses with normal umbilical artery Doppler present microstructural and metabolic brain changes, suggesting the existence of an abnormal in‐utero brain development in fetuses with this condition.

Narrativity and non‐Narrativity
Authors: Strawson Galen 
Published: June 2010

AbstractI argue against two popular claims. The first is a descriptive, empirical claim about the nature of ordinary human experience which I call the psychological Narrativity thesis (PNT). According to PNT, ‘each of us constructs and lives a “narrative” … this narrative is us, our identities’ (Sacks O. The Man Who Mistook His Wife for a Hat. London: Duckworth; 1985, 110). The second is a normative, ethical claim which I call the ethical Narrativity thesis (ENT). According to ENT, we ought to live our lives narratively, or as a story: a ‘basic condition of making sense of ourselves is that we grasp our lives in a narrative’ and have an understanding of our lives ‘as an unfolding story’ (Taylor C. Sources of the Self. Cambridge: Cambridge University Press; 1989, 47–52). On this view a person ‘creates his identity (only) by forming an autobiographical narrative—a story of his life’, and must be in possession of a full and ‘explicit narrative (of his life) to develop fully as a person’ (Schechtman M. The Constitution of Selves. Ithaca, NY: Cornell University Press; 1996, 93. WIREs Cogn Sci 2010 1 775–780This article is categorized under:

A Recess Evaluation with the Players: Taking Steps Toward Participatory Action Research
Authors: Ren Julie Yunyi , Langhout Regina Day 
Published: June 2010

AbstractThis playground study conceptualizes recess as a time and space that belongs to students; their inclusion in this evaluation is a notable difference from other recess/playground research. The goal was to help elementary school students make the changes they felt were needed on their playground. After conducting structured observations and student and recess aide focus groups, a report was presented to all stakeholders, and recess changes were made. We seek to show how the process of being inclusive during the evaluation was not only valuable for determining problem definition and potential interventions, but was also necessary to determine the best methods for solutions, move toward second‐order change, and to create a space to facilitate children's participation and empowerment.
Folate and cancer: how DNA damage, repair and methylation impact on colon carcinogenesis
Authors: Duthie Susan J. 
Published: June 2010

AbstractInappropriate diet may contribute to one third of cancer deaths. Folates, a group of water‐soluble B vitamins present in high concentrations in green, leafy vegetables, maintain DNA stability through their ability to donate one‐carbon units for cellular metabolism. Folate deficiency has been implicated in the development of several cancers, including cancer of the colorectum, breast, ovary, pancreas, brain, lung and cervix. Generally, data from the majority of human studies suggest that people who habitually consume the highest level of folate, or with the highest blood folate concentrations, have a significantly reduced risk of developing colon polyps or cancer. However, an entirely protective role for folate against carcinogenesis has been questioned, and recent data indicate that an excessive intake of synthetic folic acid (from high‐dose supplements or fortified foods) may increase human cancers by accelerating growth of precancerous lesions. Nonetheless, on balance, evidence from the majority of human studies indicates that dietary folate is genoprotective against colon cancer. Suboptimal folate status in humans is widespread. Folate maintains genomic stability by regulating DNA biosynthesis, repair and methylation. Folate deficiency induces and accelerates carcinogenesis by perturbing each of these processes. This review presents recent evidence describing how these mechanisms act, and interact, to modify colon cancer risk.

Internal jugular vein collapsibility index associated with hypovolemia in the intensive care unit patients
Authors: Killu Keith , Coba Victor , Huang Yung , Andrezejewski Tanja , Dulchavsky Scott 
Published: June 2010

Abstract

Objective
To evaluate the correlation between the internal jugular vein (IJV) collapsibility index and hypovolemia in intensive care unit (ICU) patients, using point of care ultrasound imaging.

Methods
A prospective observational study was conducted in an urban tertiary care teaching hospital, in the surgical ICU. Intensivist point-of-care sonographers performed IJV ultrasound on 31 ICU patients who were diagnosed to be hypovolemic or euvolemic by their treating ICU physicians.

Results
Hypovolemic ICU patients (16 of 31) were 50% male and 75% white with a mean age of 63 (±19) years. The variables measured between the hypovolemic and euvolemic ICU patients were the mean arterial pressure, heart rate, respiratory rate, central venous pressure (CVP). Their correlation with hypovolemia was significant (p < 0.05). The ROC curve analysis found the IJV collapsibility index ≥39% correlated best with hypovolemic ICU patient with a sensitivity of 87.5% and specificity 100%. The area under ROC curve for IJV collapsibility index was 0.938, with no significant difference to CVP with the area under ROC curve of 0.87 (p = 0.467).

Conclusion
IJV collapsibility index can be identified by intensivist point-of-care sonographers in the hypovolemic and euvolemic ICU patients. The presence of IJV collapsibility index greater than 39% may be associated with hypovolemia in ICU patients.
EvolTrack: improving design evolution awareness in software development

Published: June 2010

Abstract
Software differs from most manufactured products because it is intangible. This characteristic makes it difficult to detect, control, and understand how it evolves. This paper presents an approach based on software visualization that can detect and externalize design evolution made in a software project during its initial development or at any further phase. By using this approach, a developer can be aware of the current state of the software as a whole and can additionally verify if the current design, also called emerging design, is evolving according to the team expectations and leader guidance, preventing problems caused by misunderstandings of the expected software solution. The approach was evaluated with free/open source software (FOSS) projects. The results indicate that the approach behaves as expected when applied to real software development projects, with minor performance bottlenecks.
Effects of transdermal estradiol gel and oral tibolone on health‐related quality of life after surgical menopause
Authors: Bhattacharya Sudhindra M. , Jha Ayan 
Published: June 2010

AbstractObjectiveTo study the effects of 6 months of treatment with transdermal estradiol gel versus oral tibolone on health‐related quality of life (HRQOL) after surgical menopause.MethodsIn a randomized single‐blind trial, Indian women received either oral tibolone tablets (2.5 mg) or transdermal estradiol gel (0.06%) daily. Each woman scored herself on the Menopause Rating Scale (MRS) II at the beginning of the study and after 6 months. Independent t tests were used to determine the significance of changes in HRQOL.ResultsIn total, 31 (81.6%) women who received estradiol gel and 38 (100.0%) women who received tibolone completed treatment. Intent‐to‐treat analysis showed that, after 6 months of treatment, the total MRS score was significantly reduced in the tibolone group compared with the transdermal estradiol gel group (− 9.5 ± 5.1 versus − 4.9 ± 5.7; 95% confidence interval, 2.0–7.0; P < 0.01). Significant improvements were also noted in the tibolone group in terms of somatovegetative (P = 0.04) and psychologic (P < 0.01) domains.ConclusionOral tibolone treatment was more effective than transdermal estradiol gel at improving HRQOL in Indian women with surgical menopause.

Published: June 2010

AbstractObjectiveA cross‐sectional study in Angola to evaluate the feasibility of cervical screening using visual inspection with acetic acid (VIA) or Lugol's iodine (VILI) to detect and treat cervical intraepithelial neoplasia (CIN).MethodsAll 8851 women screened by trained nurses received colposcopy and/or colposcopically‐directed biopsies. The final disease status was based on histopathology or colposcopy when no or inadequate biopsies were done. The sensitivity, specificity, and predictive values of tests to detect CIN 2–3 were calculated.ResultsVIA was positive in 6.6% and VILI in 32.0% of the women. The positivity rates increased with time only for VILI. CIN 2–3 was diagnosed in 75 women and invasive cancer in 57. The sensitivity and specificity was 70.7% (95% CI, 59.0%–80.6%) and 94.5% (95% CI, 94.0%–95.0%) respectively for VIA, and 88.0% (95% CI, 78.4%–94.4%) and 68.9% (95% CI, 67.9%–69.9%) for VILI. Ninety percent of women detected with CIN received treatment. Treatment was given on the same day as screening to one‐third of the 374 women treated with cryotherapy/LEEP. No major complications or adverse effects were associated with treatment.ConclusionIt was feasible to screen with both visual tests and treat women with CIN in Angola. VILI was less specific than VIA, implying subjectivity in interpreting test results.

BackgroundEvidence is accumulating that child sexual abuse (CSA) is associated with many psychiatric disorders in adulthood. This paper uses the detailed information available from the 2007 Adult Psychiatric Morbidity Survey of England (APMS 2007) to quantify links between CSA and a range of psychiatric conditions.MethodThe prevalence of psychiatric disorder was established in a random sample of the English household population (n=7403), which also provided sociodemographic and experiential information.ResultsWe analyzed six types of common mental disorder, alcohol abuse and drug abuse, and people who screened positively for post-traumatic stress disorder (PTSD) and eating disorders. All were strongly and highly significantly associated with CSA, particularly if non-consensual sexual intercourse was involved, for which odds ratios (ORs) ranged from 3.7 to 12.1. These disorders were also related to adult sexual abuse (ASA), although the likelihood of reverse causality is then increased. Revictimization in adulthood was common, and increased the association of CSA with disorder. For several disorders, the relative odds were higher in females but formal tests for moderation by gender were significant only for common mental disorders and only in relation to non-consensual sexual intercourse. The population attributable fraction (PAF) was higher in females in all cases.ConclusionsThe detailed and high-quality data in APMS 2007 provided important confirmation both of the strength of association of CSA with psychiatric disorder and of its relative non-specificity. Our results have major implications at the public health level and the individual level, in particular the need for better recognition and treatment of the sequelae of CSA.
Hell and character
Authors: CORABI JOSEPH 
Published: June 2010

AbstractThe view that consignment to hell is a matter of having a fixed vicious character of a certain sort – rather than a matter of paying a retributive penalty for sin – is quite popular among philosophical theologians today. However, if proponents of this view wish to maintain that some individuals wind up consigned to hell, and if they embrace a number of independently plausible assumptions, they will be forced toward unreasonable claims about character development and its relationship to consignment to hell. In this paper, I describe the difficulties for these philosophical theologians.
From Jena to Copenhagen: Kierkegaard's relations to German idealism and the critique of autonomy inThe Sickness Unto Death
Authors: LONCAR SAMUEL 
Published: June 2010

AbstractThis article seeks to demonstrate the influence of J. G. Fichte's philosophy on Søren Kierkegaard's theory of the self as he develops it inThe Sickness unto Deathand to interpret his theory of the self as a religious critique of autonomy. Following Michelle Kosch, it argues that Kierkegaard's theory of the self was developed in part as a critique of idealist conceptions of agency. Moreover, Kierkegaard's view of agency provides a powerful way of understanding human freedom and finitude that has implications for contemporary debates about autonomy, normativity, and agency.
From hope to crisis and back again? A critical history of the global CBNRM narrative

Published: June 2010

SUMMARYCommunity-based natural resource management (CBNRM) has been on the ascendancy for several decades and plays a leading role in conservation strategies worldwide. Arriving out of a desire to rectify the human costs associated with coercive conservation, CBNRM sought to return the stewardship of biodiversity and natural resources to local communities through participation, empowerment and decentralization. Today, however, scholars and practitioners suggest that CBNRM is experiencing a crisis of identity and purpose, with even the most positive examples experiencing only fleeting success due to major deficiencies. Six case studies from around the world offer a history of how and why the global CBNRM narrative has unfolded over time and space. While CBNRM emerged with promise and hope, it often ended in less than ideal outcomes when institutionalized and reconfigured in design and practice. Nevertheless, despite the current crisis, there is scope for refocusing on the original ideals of CBNRM: ensuring social justice, material well-being and environmental integrity.
PARTIAL COMPLEMENTS IN FINITE GROUPS
Authors: CHEN INGRID 
Published: June 2010

AbstractLet G be a finite group with normal subgroup N. A subgroup K of G is a partial complement of N in G if N and K intersect trivially. We study the partial complements of N in the following case: G is soluble, N is a product of minimal normal subgroups of G, N has a complement in G, and all such complements are G-conjugate.
