Published: November 2012

Abstract
The determination of electronic states of single-walled carbon nanotubes (SWNTs) has been a central issue in science and nanotechnology of carbon nanotubes. Previously, we reported the electronic states of (n,m)SWNTs that were embedded in an anionic polymer, carboxymethylcellulose sodium salt (CMC). It is important to reveal how the electronic properties of individual (n,m)SWNTs are affected by the surrounding microenvironment. In this study, we focused on the effect of charge of the SWNT solubilizers. We used a cationic polymer, hydroxyethylcellulose ethoxylate (quaternized) (HEQ) as the SWNT solubilizer in place of CMC, and the isolated (n,m)SWNTs were embedded in a film of HEQ (matrix polymer) on an electrode. We found that the charge of HEQ virtually does not affect the electronic parameters, i.e., oxidation/reduction potentials, Fermi levels, and band gaps of the (n,m)SWNTs, indicating that the presented electronic parameters are the parameters of the intrinsic (n,m)SWNTs.

Published: November 2012

Background There is a negative glucose gradient between the capillary and venous systems, produced by glucose uptake into peripheral tissues. This gradient is augmented by oral glucose ingestion in healthy volunteers; thus prandial status may impact on capillary glucose meter performance. Our primary aim was to investigate whether the (capillary-venous plasma) glucose difference changed in relation to prandial status, in healthy volunteers. Methods Glucose was measured fasting and also one hour after an ad libitum breakfast, in 103 healthy volunteers. Duplicate capillary (finger stick) measurements were undertaken at both time points, using both the FreeStyle Lite and AccuChek Performa meters. Simultaneous venous (antecubital fossa) samples were centrifuged immediately after collection and plasma glucose was measured using the laboratory hexokinase method. Results were compared by Bland-Altman difference analysis. Results The mean (95% CI) pre- and postprandial (capillary-plasma) glucose differences (mmol/L) were calculated for each meter. For the Freestyle Lite, the preprandial difference was 20.51 (20.58 to 20.45) and postprandial difference was 0.81 (0.69-0.94). Corresponding differences for the Performa were 20.13 (20.20 to 20.06) and 1.19 (1.07-1.31), respectively. T-test comparison of participants’ paired pre- and postprandial (capillary-plasma) glucose differences confirmed a significant meal-related change in glucose estimation for both meters (P < 0.0001). Also, both meters read highest at lower glucose concentrations. Conclusions In healthy volunteers, both glucose meters showed a systematic positive bias one hour after breakfast. The significance of this finding in diabetes remains to be determined.
Interactive art in the suburbs: Art projects that increase involvement from the community
Authors: Hendahl Kicki , Aguirre Giovanna , Magnusson Evis 
Published: November 2012

ABSTRACT
In this article we examine how interactive art can be integrated into city planning. A pleasant, safe and aesthetically pleasing environment, inspired by residents’ needs and desires, has been our objective. During the last seven years, the city of Örebro has cooperated with us, three artists, to develop community-based projects aimed at raising levels of involvement amongst residents. Residents have participated in creative workshops together with the artists in order to realize a better living environment for all concerned. We have worked in close cooperation with local authorities, businesses and associations. We have applied involvement culture to suburban settings, producing both temporary artworks and more permanent changes to peoples’ quality of life. Our findings constitute a growing source of knowledge to be used to foster democratic city planning well anchored in the community. Many of the residents who became involved in the art projects, that we carried out on behalf of the municipality of Örebro, had never been given the chance to influence city planning or the creation of an artwork. We were able to create spaces and places that were not only public in name but also in content.
Hanging out is hard to do: Methodology in non-avatar environments
Authors: Woodford Darryl 
Published: November 2012

ABSTRACT
Ethnography is now a well-established research methodology for virtual environments,and the vast majority of accounts have one aspect in common, whether textual or graphic environments – that of the embodied avatar. In this article, I first discuss the applicability of such a methodology to non-avatar environments such as Eve Online, considering where the methodology works and the issues that arise in its implementation – particularly for the consideration of sub-communities within the virtual environment. Second, I consider what alternative means exist for getting at the information that is obtained through an ethnographic study of the virtual environment. To that end, I consider the practical and ethical implications of utilizing existing accounts, the importance of the meta-game discourse, including those sources outside of the control of the environment developer, and finally the utility in combining personal observations with accounts of other ethnographers, both within and between environments.
Hat die Philosophie noch eine Einheit?
Authors: Leist Anton 
Published: November 2012

Abstract
Today philosophy falls apart into a “theoretical” and a “practical” sub-discipline, a situation to the detriment of both. On the back of a sketch of three stages of Western philosophy a diagnosis is made as to the practical origin of the theoretical/practical split, which also already contains within it the clue for a therapy. Both parts of philosophy could be set on a convergent path by recognizing two practical conflicts underlying philosophical problems: the biographical conflict of accepting the world and the social conflict of accepting others. A non-reductivist study of these conflicts might mitigate the present alienation within philosophy.
Genetic Analysis of Vertebral Regionalization and Number in Medaka (Oryzias latipes) Inbred Lines
Authors: Kimura Tetsuaki , Shinya Minori , Naruse Kiyosi 
Published: November 2012

Abstract
Vertebral number is the most variable trait among vertebrates. In addition to the vertebral number, the ratio of abdominal to caudal vertebrae is a variable trait. The vertebral number and the ratio of abdominal to caudal vertebrae contribute to vertebrate diversity. It is very interesting to know how to determine the vertebral number and the ratio of abdominal to caudal vertebrae. In this study, we identify differences in the vertebral number and the ratio of abdominal vertebrae to vertebral number between two inbred lines of medaka, namely, Hd-rRII1 and Kaga. To identify the genetic factor of those differences, we performed quantitative trait locus (QTL) analysis for vertebral number and the ratio of abdominal vertebrae to vertebral number using 200 F2 fish. Our results show a suggestive QTL of the ratio of abdominal vertebrae to vertebral number on chromosome 15, and five QTL of vertebral number on chromosomes 1, 10, 11, 17, and 23. The QTL on chromosome 15 contains hoxDb cluster genes. The QTL of vertebral number include some genes related to the segmentation clock and axial elongation. In addition, we show that the difference in vertebral number between two inbred lines is derived from differences in the anteroposterior length of somites. Our results emphasize that the developmental process should be considered in genetic analyses for vertebral number.

AbstractTransposon-based forward and reverse genetic technologies will contribute greatly to ongoing efforts to study mosquito functional genomics. A piggyBac transposon-based enhancer-trap system was developed that functions efficiently in the human malaria vector, Anopheles stephensi. The system consists of six transgenic lines of Anopheles stephensi, each with a single piggyBac-Gal4 element in a unique genomic location; six lines with a single piggyBac-UAStdTomato element; and two lines, each with a single Minos element containing the piggyBac-transposase gene under the regulatory control of the hsp70 promoter from Drosophila melanogaster. Enhancer detection depended upon the efficient remobilization of piggyBac-Gal4 transposons, which contain the yeast transcription factor gene Gal4 under the regulatory control of a basal promoter. Gal4 expression was detected through the expression of the fluorescent protein gene tdTomato under the regulatory control of a promoter with Gal4-binding UAS elements. From five genetic screens for larval- and adult-specific enhancers, 314 progeny were recovered from 24,250 total progeny (1.3%) with unique patterns of tdTomato expression arising from the influence of an enhancer. The frequency of piggyBac remobilization and enhancer detection was 2.5- to 3-fold higher in female germ lines compared with male germ lines. A small collection of enhancer-trap lines are described in which Gal4 expression occurred in adult female salivary glands, midgut, and fat body, either singly or in combination. These three tissues play critical roles during the infection of Anopheles stephensi by malaria-causing Plasmodium parasites. This system and the lines generated using it will be valuable resources to ongoing mosquito functional genomics efforts.

Published: November 2012

OBJECTIVE:
Prevalence of overweight in children is increasing, causing various health problems. This study aims to establish growth references for weight and to assess the prevalence rates of overweight and obesity in a nationwide sample of Dutch children with Down syndrome (DS), taking into account the influence of comorbidity.

METHODS:
In 2009, longitudinal growth data from Dutch children with trisomy 21 who were born after 1982 were retrospectively collected from medical records of 25 Dutch regional specialized DS centers. “Healthy” was defined as not having concomitant disorders or having only a mild congenital heart defect. Weight and BMI references were calculated by using the LMS method, and prevalence rates of overweight and obesity by using cutoff values for BMI as defined by the International Obesity Task Force. Differences in prevalence rates were tested by multilevel logistic regression analyses to adjust for gender and age.

RESULTS:
Growth data of 1596 children with DS were analyzed. Compared with the general Dutch population, healthy children with DS were more often overweight (25.5% vs 13.3% in boys, and 32.0% vs 14.9% in girls) and obese (4.2% vs 1.8%, and 5.1% vs 2.2%, respectively). Prevalence rates of overweight between DS children with or without concomitant disorders did not vary significantly.

CONCLUSIONS:
Dutch children with DS have alarmingly high prevalence rates of overweight and obesity during childhood and adolescence. Health care professionals should be aware of the risk of overweight and obesity in children with DS to prevent complications.
Effectiveness of Protective Eyewear in Reducing Eye Injuries Among High School Field Hockey Players
Authors: Kriz Peter K. , Comstock R. Dawn , Zurakowski David , Almquist Jon L. , Collins Christy L. , d’Hemecourt Pierre A. 
Published: November 2012

OBJECTIVE:
To determine if injury rates differ among high school field hockey players in states that mandated protective eyewear (MPE) versus states with no protective eyewear mandate (no MPE).

METHODS:
We analyzed field hockey exposure and injury data collected over the 2009–2010 and 2010–2011 scholastic seasons from national and regional databases.

RESULTS:
Incidence of all head and face injuries (including eye injuries, concussion) was significantly higher in no-MPE states compared with MPE states, 0.69 vs 0.47 injuries per 1000 athletic exposures (incidence rate ratio [IRR] 1.47; 95% confidence interval [CI]: 1.04–2.15, P = .048). Players in the no-MPE group had a 5.33-fold higher risk of eye injury than players in the MPE group (IRR 5.33; 95% CI: 0.71–39.25, P = .104). There was no significant difference in concussion rates for the 2 groups (IRR 1.04; 95% CI: 0.63–1.75, P = .857). A larger percentage of injuries sustained by athletes in the no-MPE group required &gt;10 days to return to activity (32%) compared with athletes in the MPE group (17%), but this difference did not reach statistical significance (P = .060).

CONCLUSIONS:
Among high school field hockey players, playing in a no-MPE state results in a statistically significant higher incidence of head and face injuries versus playing in an MPE state. Concussion rates among players in MPE and no-MPE states were similar, indicating that addition of protective eyewear did not result in more player-player contact injuries, challenging a perception in contact/collision sports that increased protective equipment yields increased injury rates.
ChIP-Chip Identifies SEC23A, CFDP1, and NSD1 as TFII-I Target Genes in Human Neural Crest Progenitor Cells
Authors: Makeyev Aleksandr V. , Bayarsaihan Dashzeveg 
Published: November 2012

Objectives GTF2I and GTF2IRD1 genes located in Williams-Beuren syndrome (WBS) critical region encode TFII-I family transcription factors. The aim of this study was to map genomic sites bound by these proteins across promoter regions of developmental regulators associated with craniofacial development. Design Chromatin was isolated from human neural crest progenitor cells and the DNA-binding profile was generated using the human RefSeq tiling promoter ChIP-chip arrays. Results TFII-I transcription factors are recruited to the promoters of SEC23A, CFDP1, and NSD1 previously defined as TFII-I target genes. Moreover, our analysis revealed additional binding elements that contain E-boxes and initiator-like motifs. Conclusions Genome-wide promoter binding studies revealed SEC23A, CFDP1, and NSD1 linked to craniofacial or dental development as direct TFII-I targets. Developmental regulation of these genes by TFII-I factors could contribute to the WBS-specific facial dysmorphism.

Objective This study analyzed the influence of autogenous white adipose tissue on bone matrix development in critical-size defects created in rabbit calvaria. Materials and Methods A 15-mm-diameter defect was created in the calvaria of 42 rabbits. Twenty-one rabbits were treated with 86 mm3 of immediate transplant of fragmented white subcutaneous adipose tissue (WSAT); the others constituted the control group (sham). The animals were euthanized at 7, 15, and 40 days postsurgery (n = 7), and the histological data were analyzed by histomorphometry and immunohistochemistry using the anti-adiponectin and parathyroid hormone 1-receptor (PTH1R) antibodies. Results The calvariae treated with fragmented WSAT demonstrated significant bone formation. These results coincided with the significant presence of immunopositivity to adiponectin and PTH1R in loci, which in turn coincided with the increase in bonelike matrix deposited both in fat tissue stroma and adipocytes' cytoplasm. In contrast, the control group revealed a small amount of bone-matrix deposition and presented scarce PTH1R expression and a lack of immunostain for adiponectin. Conclusion These results indicate that transplant of fragmented white subcutaneous adipose tissue may be an alternative to treatment of craniofacial bone deformities because adipose tissue suffers from osseous metaplasia and exhibits immunoexpression of the adiponectin and PTH1R, which are proteins associated with bone metabolism
Demand-Based Cost-of-Children Estimates and Child Poverty
Authors: Garcia-Diaz Rocio 
Published: November 2012

Abstract
This paper compares alternative demand-based equivalence scales for the cost of children to assess child poverty in Mexico. The models estimated here range from single-equation models, such as those of Engel and Rothbarth, to a complete demand system approach with fixed price effects. The results found in this study favor the generalization of the complete demand system equivalence scales over the other models. Despite the differences in the alternative models, the ranking of households with children and overall populations is insensitive to different equivalence scales and poverty lines used. However, variation in the composition of poor households with children has a different effect depending on the particular choice of equivalence scale. We found that, for households with more than the country's average number of children, poverty incidence is considerably higher than in the population as a whole.
Co-Creating Value from IT in a Contracted Public Sector Service Environment: Perspectives on COBIT and Val IT
Authors: Wilkin Carla , Campbell John , Moore Stephen , Van Grembergen Wim 
Published: November 2012

ABSTRACT
Research that examines Information Technology (IT) value has called for studies to explore the co-creation of value, including in multi-firm environments. This study draws upon the practice of IT governance in a successful large-scale IT deployment, wherein private and public firms were involved as customer service providers with the principal, a large government department. Drawing on customer-centric co-creation concepts from marketing research, through comparative analysis and related application to our case study, we detail the merit of a service-oriented approach to co-creating value from IT and the assistance COBIT and Val IT can provide. Importantly, we identified determinates of co-created value in a multi-firm environment, although our analysis reveals some need to evolve COBIT and Val IT to improve guidance regarding the mechanisms required to achieve this in such environments.
Management Motive, Weak Governance, Earnings Management, and Fraudulent Financial Reporting: Malaysian Evidence

Published: November 2012

ABSTRACT
This study examines ten factors associated with fraudulent financial reporting (FFR) in Malaysian publicly listed companies. We hypothesize that three factors proxy for management rationalization, four factors proxy for management motives, and three factors proxy for the opportunity to commit fraud. Our sample consists of 53 fraud firms convicted of securities fraud and 53 no-fraud firms, all of which were listed on the Bursa Malaysia and have a complete set of data from 1996–2007. With regard to rationalization, we find that prior violations and founders on the board are positively and significantly associated with FFR. With regard to motive, we find that financial distress is positively and significantly associated with FFR while family ownership is negatively and significantly associated with FFR. Our opportunity for fraud proxies, multiple directorships, and audit quality are positively and significantly associated with FFR. Additionally, we find evidence of earnings management in the years leading up to FFR.
Monitoring on-going vision development in system change programmes
Authors: Taanman Mattijs , Wittmayer Julia M. , Diepenmaat Henk 
Published: November 2012

Abstract
Visions are considered to be of vital importance for programmes aimed at sustainable systems change. Vision development is a programme management instrument, a programme output, and at the heart of programme learning processes. This article addresses the question what constitutes an appropriate monitoring strategy for vision development activities within system change programmes. Based on action research and literature review on monitoring, evaluation and vision development a monitoring framework is proposed. It is suggested to monitor the programme vision against project visions, societal visions and a set of basic criteria. The monitoring activities themselves are context-sensitive and frequently renegotiated between monitors, programme managers and other stakeholders. The framework is illustrated with a national systems change programme on sustainable agriculture in the Netherlands.
Sustainable food purchases in the Netherlands: the influence of consumer characteristics
Authors: Meijers Marijn H.C. , Van Dam Ynte K. 
Published: November 2012

Abstract
In this paper socio-demographic characteristics of sustainable food consumers are studied by using actual purchasing data of 4,412 households in a wide range of food products over a twenty week period in the months November 2008 till March 2009. Our results indicate that purchasing sustainable food products is still the exception rather than the rule. Socio-demographic characteristics are (weakly) related to the purchasing sustainable food items. Specifically, people with a higher education and those living in a more urban area are more likely to purchase sustainable products. Psychographic data on a subsample (n=1,112) show a weak relation between sustainability concerns and sustainable behaviour. Scales measuring people’s sustainability concerns specific to purchasing products (e.g. Ethical orientation scale) are better predictors of people’s sustainable consumption than scales measuring people’s general sustainability concerns (e.g. Connectedness to Nature scale). Since consumer characteristics seem to be of little predictive value of sustainable consumption it may be wise to shift the focus from investigating who the sustainable consumer is to how to make sustainable products successful. In the discussion we offer some initial guiding principles.

Authors: El Matri Leila , Bouladi Mejda , Chebil Ahmed , Kort Fedra , Bouraoui Rym , Largueche Leila , Mghaieth Fatma 
Published: November 2012

BACKGROUND AND OBJECTIVE:
To measure macular choroidal thickness (CT) using spectral-domain optical coherence tomography (OCT) and to investigate the correlation between CT and age, degree of myopia, and history of macular choroidal neovascularization (CNV).

PATIENTS AND METHODS:
A cross-sectional study included 187 highly myopic eyes of 187 patients examined between January and December 2010. The choroid was imaged with spectral-domain OCT by changing the reference position from the vitreous to the choroid. CT was measured from the outer border of the hyperreflective line corresponding to the retinal pigment epithelium to the inner scleral border.

RESULTS:

The mean age was 47.21 ± 14.24 years, the mean spherical equivalent refractive error was −13.66 ± 5.77, and the mean subfoveal CT was 100.71 ± 59.98 μm. CT was correlated negatively with age (
P
< 10
−3
) and refractive error (
P
< 10
−3
). Forty-two eyes had a history of CNV, the mean CT was 55.45 ± 24.46 μm, and this was significantly thinner than in eyes without CNV (
P
< 10
−3
).

CONCLUSION:
In highly myopic eyes, the choroid is thin and undergoes further attenuation with age and increasing myopia. In addition, these findings suggest that the choroid may play a role in the pathogenesis of CNV.
