Playful mobile communication: Services supporting the culture of play
Authors: Mäyrä Frans 
Published: November 2012

Communication has many functions; from linguistics to social psychology, there is ample evidence that communication fundamentally defines our ways of being, which is the reason changes in communicational practices and technologies are particularly interesting. This article focuses on
the recent developments in playful mobile communication, firstly discussing play and playful practices in general, then moving on to contextualize the discussion in terms of contemporary mobile technology. Not just restricted to formal game play (ludus) but also including more improvisational
forms of being playful (paidia), mobile play allows us some creative distance from the routine ways of communicating and is consequently more free-form than the more immediately utilitarian communicative acts. Playfulness also has certain distinctive features and it is possible to identify
and discuss playfulness as it is expressed in the design of new tools for communication, as well as in the communicative practices and attitudes dopted by the participants. This article provides an introduction to the study of playful communication, and proposes three key evaluation
criteria for playfulness. It then proceeds to test these criteria in contemporary playful mobile communication services.

Abstract
Natural radioactivity in the crude oil, produced water, sludge and scale wastes from the petroleum industry on the Suez gulf (Abu Redeis), Egypt were investigated. A low radioactivity was found in the produced water and crude oil samples. In the sludge waste samples, the levels of radioactivity were found to be 11.96 and 1.75 kBq kg−1 for Ra-226 (of U-series) and Ra-228 (of Th-series), respectively. In the scale waste samples, the levels of radioactivity were 11.7 and 4.2 kBq kg−1 for Ra-226 and Ra-228, respectively. Leaching of different radionuclides in the sludge and scale wastes was investigated using mineral acid alone or after treatment with certain carbonate solutions. The different parameters affecting the treatment were optimized. It is found that high removal of Ra-226 was achieved from sludge and scale wastes when pretreated with 10% sodium carbonate solution, followed by acid dissolution. Removal % of Ra-226 reached 77 and 87% from the sludge and scale wastes, respectively.
The covariance structure of cml-estimates in the Rasch model
Authors: Strasser Helmut 
Published: November 2012

AbstractIn this paper we consider conditional maximum likelihood (cml) estimates for item parameters in the Rasch model under random subject parameters. We give a simple approximation for the asymptotic covariance matrix of the cml-estimates. The approximation is stated as a limit theorem when the number of item parameters goes to infinity. The results contain precise mathematical information on the order of approximation.The results enable the analysis of the covariance structure of cml-estimates when the number of items is large. Let us give a rough picture. The covariance matrix has a dominating main diagonal containing the asymptotic variances of the estimators. These variances are almost equal to the efficient variances under ml-estimation when the distribution of the subject parameter is known. Apart from very small numbersnof item parameters the variances are almost not affected by the numbern. The covariances are more or less negligible when the number of item parameters is large. Although this picture intuitively is not surprising it has to be established in precise mathematical terms. This has been done in the present paper.The paper is based on previous results [6] of the author concerning conditional distributions of non-identical replications of Bernoulli trials. The mathematical background are Edgeworth expansions for the central limit theorem. These previous results are the basis of approximations for the Fisher information matrices of cml-estimates. The main results of the present paper are concerned with the approximation of the covariance matrices.Numerical illustrations of the results and numerical experiments based on the results are presented in Strasser [5].

Published: November 2012

Zusammenfassung
Mehrachsige Kraftsensoren gibt es praktisch nur als hochpräzise, aber auch sehr teure Ausführungen auf dem Markt. Dadurch wird ihre Anwendung in vielen Bereichen, die zwar größere Stückzahlen brauchen, aber nur niedrigere Kosten akzeptieren können, stark eingeschränkt; z. B. im Bereich der Medizin- und Rehatechnik oder der Kraftsensorgesteuerten Robotik. Hier wird ein innovativer Konzept für einen 6-achsigen Kraftsensor vorgestellt, der es erlaubt, in kostengünstigen automatisierten Verfahren solche Sensoren in großen Stückzahlen und mit ausreichender Qualität herzustellen, um diese neuen Anwendungen zu erschließen. Das Konzept wurde theoretisch ausgearbeitet und experimentell an Labor-Konzept-Demonstratoren validiert. Das Konzept kann bei konkreten Anforderungen in einem entsprechenden Produkt umgesetzt werden.

ContextPseudohypoparathyroidism type Ib (PHP-Ib) is a rare disorder resulting from genetic and epigenetic aberrations in the GNAS complex. PHP-Ib, usually defined by renal resistance to parathyroid hormone, is due to a maternal loss of GNAS exon A/B methylation and leads to decreased expression of the stimulatory G protein α (Gsα) in specific tissues.ObjectiveTo clarify the usefulness of methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA), we evaluated genetic and epigenetic changes of the GNAS locus in Japanese PHP-Ib patients.DesignRetrospective case series.PatientsWe studied 13 subjects with PHP-Ib (three families with eight affected members and one unaffected member and four sporadic cases).MeasurementsThe methylation status of GNAS differentially methylated regions (DMRs) was evaluated using MS-MLPA. The main outcome measure was the presence of deletion mutations in the GNAS locus and STX16, which were assessed using MLPA.ResultsIn all familial PHP-Ib cases, a ∼3 kb deletion of STX16 and demethylation of the A/B domain were identified. In contrast, no deletion was detected throughout the entire GNAS locus region in the sporadic cases. Broad methylation abnormalities were observed in the GNAS DMRs.ConclusionsMS-MLPA allows for precise and rapid analysis of the methylation status in GNAS DMRs as well as the detection of microdeletion mutations in PHP-Ib. Results confirm the previous findings in this disorder and demonstrate that this method is valuable for the genetic evaluation and visualizing the methylation status. The MS-MLPA assay is a useful tool that may facilitate making the molecular diagnosis of PHP-Ib.

ObjectivePatients with active acromegaly have an increased prevalence of cardiomyopathy and heart failure but a less than expected risk of coronary artery disease, considering the frequent association of diabetes mellitus and hypertension. We examined whether changes in high-sensitive C-reactive protein (hs-CRP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) might contribute to this phenomenon.Design and methodsTwo hundred patients of the Belgian acromegaly registry (AcroBel) were divided in two groups: active disease (IGF1 Z-score >2; n=95) and controlled disease (IGF1 Z-score ≤2; n=105). Serum levels of hs-CRP and NT-proBNP were measured and correlated with BMI, blood pressure, fasting lipids, fasting glucose and insulin, HbA1c, IGF1, interleukin 6 (IL6), adiponectin, and sE-selectin. In a subset of acromegaly patients, hs-CRP, IL6, and NT-proBNP levels were also compared with those/the values of an age-, gender-, and BMI-matched reference group.ResultsPatients with active acromegaly had significantly lower levels of hs-CRP (median (interquartile range), 0.5 mg/l (0.1, 0.9) vs 1.3 mg/l (0.5, 4.1); P<0.001) and NT-proBNP, (47.0 ng/l (26.0, 86.0) vs 71.0 ng/l (43.0, 184.0); P<0.001) compared with patients with controlled acromegaly. Compared with the reference population, hs-CRP was not different in controlled acromegaly but significantly lower in active acromegaly (median, 0.4 mg/l (0.1, 0.8) vs 1.4 mg/l (0.8, 2.9); P<0.001), while NT-proBNP was similar in active acromegaly but significantly higher in controlled acromegaly (66.5 ng/l (40.0, 119.5) vs 50.8 ng/l (26.5, 79.7); P<0.001).ConclusionsPatients with active acromegaly have significantly lower values of NT-proBNP and hs-CRP compared with patients with controlled disease and even lower values of hs-CRP compared with control subjects.

ObjectiveTo study the clinical presentation, diagnostic approach, response to treatment, and the presence of other pathologies in patients with gastric carcinoid type 1 (GC 1) tumors.Design and methodsRetrospective analysis of 111 patients from four institutions and a mean follow-up of 76 months.ResultsThe main indications for gastroscopy were upper gastrointestinal tract symptoms. The mean number of lesions, maximum tumoral diameter, and percentage of cells expressing Ki-67 labeling index were 3.6±3.8, 8±12.1 mm and 1.9±2.4% respectively. Serum gastrin and chromogranin A (CgA) levels were elevated in 100/101 and 85/90 patients respectively. Conventional imaging studies demonstrated pathology in 9/111 patients. Scintigraphy with radiolabeled octreotide was positive in 6/60 without revealing any additional lesions. From the 59 patients who had been followed-up without any intervention, five developed tumor progression. Thirty-two patients were treated with long-acting somatostatin analogs (SSAs), leading to a significant reduction of gastrin and CgA levels, number of visible tumors, and CgA immune-reactive tumor cells in 28, 19, 27, and 23 treated patients respectively. Antrectomy and/or gastrectomy were initially performed in 20 patients and a complete response was achieved in 13 patients. The most common comorbidities were vitamin B12 deficiency, thyroiditis, and parathyroid adenomas.ConclusionsMost GCs1 are grade 1 (82.7%) tumors presenting with stage I (73.9%) disease with no mortality after prolonged follow-up. Ocreoscan did not provide further information compared with conventional imaging techniques. Treatment with SSAs proved to be effective for the duration of administration.

OBJECTIVE:To determine if an intervention for preschool-aged children in primary care is effective in reducing screen time, meals in front of the television, and BMI.METHODS:A randomized controlled trial was conducted at a primary care pediatric group practice in Toronto, Canada. Three-year-old children and their parents were randomly assigned to receive a short behavioral counseling intervention on strategies to decrease screen time. The primary outcome 1 year later was parent reported screen time. Secondary outcomes included television in the child’s bedroom, number of meals in front of the television, and BMI.RESULTS:In the intention-to-treat analysis at 1 year, there were no significant differences in mean total weekday minutes of screen time (60, interquartile range [IQR]: 35–120 vs 65, IQR: 35–120; P = .68) or mean total weekend day minutes of screen time (80, IQR: 45–130 vs 90, IQR: 60–120; P = .33) between the intervention and control group. Adjusting for baseline BMI, there was a reduction in the number of weekday meals in front of the television (1.6 ± 1.0 vs 1.9 ± 1.2; P = .03) but no differences in BMI or number of televisions in the bedroom.CONCLUSIONS:This pragmatic trial was not effective in reducing screen time or BMI but was effective in reducing meals in front of the screen. Short interventions focused solely on reducing screen time implemented in the primary care practice setting may not be effective in this age group.
15-Year Follow-Up of Recurrent “Hypoglycemia” in Preterm Infants
Authors: Tin Win , Brunskill Greta , Kelly Tom , Fritz Susan 
Published: November 2012

BACKGROUND:Observational study of 543 infants who weighed &lt;1850 g, published in 1988 reported seriously impaired motor and cognitive development at 18 months in those with recurrent, asymptomatic hypoglycemia (plasma glucose level ≤2.5 mmol/L on ≥3 days). No study has yet replicated this observation.AIM:To quantify disability in a similar cohort of children followed up throughout childhood.POPULATION:All children born at &lt;32 weeks’ gestation in the north of England in 1990–1991 and had laboratory blood glucose levels measured daily for the first 10 days of life.RESULTS:Forty-seven index children of the 566 who survived to 2 years had a blood glucose level of ≤2.5 mmol/L on ≥3 days. All of these children and hypoglycemia-free controls, matched for hospital of care, gestation, and birth weight, were assessed at age 2. No differences in developmental progress or physical disability were detected. The families were seen again when the children were 15 years old, and 38 of the index children (81%) and matched controls agreed to detailed psychometric assessment. Findings in the 2 groups were nearly identical (mean full-scale IQ: 80.7 vs 81.2). Findings in the 21 children with a level of ≤2.5 mmol/L on ≥4 days, 7 children with a level this low on 5 days, and 11 children with a level of &lt;2.0 mmol/L on 3 different days did not alter these conclusions.CONCLUSIONS:This study found no evidence to support the belief that recurrent low blood glucose levels (≤2.5 mmol/L) in the first 10 days of life usually pose a hazard to preterm infants.

Published: November 2012

OBJECTIVE:
To determine whether state booster seat laws were associated with decreased fatality rates in children 4 to 7 years of age in the United States.

METHODS:
Retrospective, longitudinal analysis of all motor vehicle occupant crashes involving children 4 to 7 years of age identified in the Fatality Analysis Reporting System from January 1999 through December 2009. The main outcome measure was fatality rates of motor vehicle occupants aged 4 to 7 years. Because most booster laws exclude children 6 to 7 years of age, we performed separate analyses for children 4 to 5, 6, and 7 years of age.

RESULTS:
When controlling for other motor vehicle legislation, temporal and economic factors, states with booster seat laws had a lower risk of fatalities in 4- to 5-year-olds than states without booster seat laws (adjusted incidence rate ratio 0.89; 95% confidence interval [CI] 0.81–0.99). States with booster seat laws that included 6-year-olds had an adjusted incidence rate ratio of 0.77 (95% CI 0.65–0.91) for motor vehicle collision fatalities of 6-year-olds and those that included 7-year-olds had an adjusted incidence rate ratio of 0.75 (95% CI, 0.62–0.91) for motor vehicle collision fatalities of 7-year-olds.

CONCLUSIONS:
Booster seat laws are associated with decreased fatalities in children 4 to 7 years of age, with the strongest association seen in children 6 to 7 years of age. Future legislative efforts should extend current laws to children aged 6 to 7 years.

OBJECTIVE:Fever without an apparent source is common in young children. Currently in the United States, serious bacterial infection is unusual. Our objective was to determine specific viruses that might be responsible.METHODS:We enrolled children aged 2 to 36 months with temperature of 38°C or greater without an apparent source or with definite or probable bacterial infection being evaluated in the St Louis Children’s Hospital Emergency Department and afebrile children having ambulatory surgery. Blood and nasopharyngeal swab samples were tested with an extensive battery of virus-specific polymerase chain reaction assays.RESULTS:One or more viruses were detected in 76% of 75 children with fever without an apparent source, 40% of 15 children with fever and a definite or probable bacterial infection, and 35% of 116 afebrile children (P &lt; .001). Four viruses (adenovirus, human herpesvirus 6, enterovirus, and parechovirus) were predominant, being detected in 57% of children with fever without a source, 13% of children with fever and definite or probable bacterial infection, and 7% of afebrile children (P &lt; .001). Thirty-four percent of 146 viral infections were detected only by polymerase chain reaction performed on blood. Fifty-one percent of children with viral infections and no evidence of bacterial infection were treated with antibiotics.CONCLUSIONS:Viral infections are frequent in children with fever without an apparent source. Testing of blood in addition to nasopharyngeal secretions expanded the range of viruses detected. Future studies should explore the utility of testing for the implicated viruses. Better recognition of viruses that cause undifferentiated fever in young children may help limit unnecessary antibiotic use.
The Evolution of Androconia in Mimetic Tiger Moths (Noctuoidea: Erebidae: Arctiinae: Ctenuchina and Euchromiina)
Authors: Simmons Rebecca B , Weller Susan J , Johnson Sarah J 
Published: November 2012

AbstractTiger moth courtship involves an intricate interplay of female calling and male responses, involving pheromones, ultrasound, or both. A comparative phylogenetic approach is needed to separate proximal (ecological) from ultimate (evolutionary) explanations for observed behaviors. This study focused on mimetic tiger moths (Ctenuchina and Euchromiina) to provide a phylogeny to understand the evolution of male courtship structures (androconia). Genetic data from one mitochondrial gene (1,173 basepairs [bp] of COI) and two nuclear genes (238 bp of 28S rRNA D1 loop; 650 bp of EF1-α) were sampled for 29 species and analyzed using maximum parsimony, maximum likelihood, and Bayesian methods to estimate phylogenetic relationships. The ancestral reconstruction of androconia was optimized using parsimony and Bayesian approaches. Excluding three species, Euchromiina and Ctenuchina were recovered as reciprocally monophyletic, contradicting earlier molecular phylogenies. The genus Cosmosoma was found to be polyphyletic, as was Eucereon. Reconstruction of androconial structures revealed that these structures were acquired once, with subsequent losses in particular species.
Analysis of 20-OH-Ecdysone Titers in Ostrinia furnacalis Affected by Azadirachtin Using Capillary Zone Electrophoresis
Authors: Huang Zhiwei , Zhao Min , Zhou Li , Shi Ping 
Published: November 2012

Abstract
A novel technique of insect ecdysone analysis was established by capillary zone electrophoresis using 20-hydroxy ecdysone (purity ≥93%) as a standard sample. It showed that 20-hydroxy ecdysone and other trace impurities were completely separated within 5 min with an electrolyte containing 10 mmol/L borate, at pH 9.18, 20 kV applied voltage and 0.5 psi × 5 s injected volume. Under this optimal condition, effects of azadirachtin on ecdysone in the hemolymph of Ostrinia furnacalis (Guenee) were investigated. The results showed that the peak values of 20-hydroxy ecdysone were strongly suppressed by azadirachtin and the titers remained at a lower level than those in the control samples. When compared with high-performance liquid chromatography, the primary advantages of capillary zone electrophoresis include a much shorter analysis time and detection limit and the elimination of complex pretreatment of samples.
Larval Food Supply Constrains Female Reproductive Schedules inHippodamia convergens(Coleoptera: Coccinellidae)
Authors: Vargas German , Michaud J P , Nechols James R 
Published: November 2012

AbstractReproductive schedules are a critical aspect of life history intrinsically linked to a species' ecology. We explored dynamic trajectories of daily fecundity, egg size, and egg fertility in three size classes of Hippodamia convergens Guerin-Meneville produced by varying larval access to food, eggs of Ephestia kuehniella Zeller. Adult pairs were held with ad libitum food and eggs were collected daily, counted, and a subsample measured. Egg fertility declined steeply over 25 clutches in small females, gradually in large females, but remained relatively stable in medium females. In small females, egg size and daily fecundity declined in a linear manner. There was no clear indication of an egg size-number tradeoff. In medium females, both egg size and daily fecundity peaked around the 16th day of oviposition, after which both declined. Large females began oviposition earlier and achieved peak egg size about day 7, and peak fecundity around day 12. Large females thus expressed a larger proportion of their reproductive effort early in adult life, a strategy inferred to be adaptive in the context of aphidophagy; a larger proportion of progeny would develop early in the exponential growth phase of the prey population when food is most abundant. Increases in egg size during this period may improve the survival of later-developing progeny; prey become scarce as aphid outbreaks decline and competition intensifies, favoring offspring with a larger body size at eclosion. Larval diet restriction appeared to constrain these presumably adaptive changes in egg size and daily fecundity, largely through effects on maternal body size.
