Introduction to Felipe Ehrenberg's “In Search of a Model for
Life”
Authors: Benezra Karen 
Published: April 2012

Abstract
“In Search of a Model for Life” traces a brief history of the autonomous, experimental art movement known as los Grupos (the Groups) in which the essay’s author, Felipe Ehrenberg, played a central role. Based mostly in Mexico City in the late 1970s, the Groups critiqued the predominant academicism as well as the burgeoning support for commercially viable experimental work in Mexico’s state-run art institutions. “In Search of a Model for Life” first appeared as one of three external appendices to the catalog for the Museo de Arte Carrillo Gil’s 1985 retrospective of the Groups, De los Grupos los individuos (From the Groups, Individuals). Ehrenberg’s essay challenges the teleological narrative that the catalog’s text traces, from a collective movement of rebellion to the individual insertion of the movement’s members into the art market. In doing so, “In Search of a Model for Life” begins to theorize the conditions for a critical and emancipatory art practice beyond the complicity of state and market.
An Asymmetry in the IOD and ENSO Teleconnection Pathway and Its Impact on Australian Climate
Authors: Cai Wenju , van Rensch Peter , Cowan Tim , Hendon Harry H. 
Published: April 2012

Abstract
Recent research has shown that the climatic impact from El Niño–Southern Oscillation (ENSO) on middle latitudes west of the western Pacific (e.g., southeast Australia) during austral spring (September–November) is conducted via the tropical Indian Ocean (TIO). However, it is not clear whether this impact pathway is symmetric about the positive and negative phases of ENSO and the Indian Ocean dipole (IOD). It is shown that a strong asymmetry does exist. For ENSO, only the impact from El Niño is conducted through the TIO pathway; the impact from La Niña is delivered through the Pacific–South America pattern. For the IOD, a greater convection anomaly and wave train response occurs during positive IOD (pIOD) events than during negative IOD (nIOD) events. This “impact asymmetry” is consistent with the positive skewness of the IOD, principally due to a negative skewness of sea surface temperature (SST) anomalies in the east IOD (IODE) pole. In the IODE region, convection anomalies are more sensitive to a per unit change of cold SST anomalies than to the same unit change of warm SST anomalies. This study shows that the IOD skewness occurs despite the greater damping, rather than due to a breakdown of this damping as suggested by previous studies. This IOD impact asymmetry provides an explanation for much of the reduction in spring rainfall over southeast Australia during the 2000s. Key to this rainfall reduction is the increased occurrences of pIOD events, more so than the lack of nIOD events.
Hourly Rainfall Changes in Response to Surface Air Temperature over Eastern Contiguous China
Authors: Yu Rucong , Li Jian 
Published: April 2012

Abstract
In this study, late-summer rainfall over eastern contiguous China is classified according to hourly intensity and the changes of moderate, intense, and extreme precipitation in response to variation of surface air temperature are analyzed. The e-folding decay intensity (Imi) derived from the exponential distribution of rainfall amount is defined as the threshold that partitions rainfall into moderate and intense rainfall, and the double e-folding decay intensity (Ie) is used as the threshold to pick out extreme cases. The mean values of Imi and Ie are about 12 and 24 mm h−1, respectively. Between the two periods, 1966–85 and 1986–2005, the ratio between moderate and intense rainfall has experienced significant changes. And the spatial pattern of changes in the percentage of moderate rainfall presents a direct relation with that of the surface air temperature. Based on temperature changes, three regimes, regime N (north China), regime C (central eastern China), and regime S (southeastern coastal area of China), are defined. In warming regimes (regimes N and S), the percentage of moderate rainfall exhibits a decreasing trend. In regime C, where the temperature has fallen, the percentage of moderate rainfall increased prominently. In all three regimes there are significant negative (positive) correlations between the percentage of moderate (intense) rainfall and the temperature. The relation between the extreme rainfall and the surface air temperature is far more regionally dependent. With plenty of water supply and little change in relative humidity, the extreme rainfall increased in regime S. Although regime N also shows strong warming trends, there is no significant trend in extreme precipitation due to the lack of water vapor transportation.
The Signature of Inertial and Tidal Currents in Offshore Wave Records
Authors: Gemmrich Johannes , Garrett Chris 
Published: April 2012

Abstract
The roughness of the sea surface can be affected by strong currents. Here, long records of surface wave heights from buoy observations in the northeastern Pacific Ocean are examined. The data show the influence of tidal currents, but the first evidence of wave-height modulation (up to 20%) at a frequency that is slightly higher than the local inertial frequency is also found. This finding shows the effect on surface waves of near-inertial currents, which are typically the most energetic currents in the open ocean. The result has implications for wave forecasting but also provides valuable information on the frequency, strength, and intermittency of the associated near-inertial motions.
Does Body Mass Index Accurately Reflect Body Fat? A Comparison of Anthropometric Measures in the Longitudinal Assessment of Fat Mass

Published: April 2012

Objective To determine which anthropometric measure best correlates with change in fat mass (FM) over time. Methods The authors performed a retrospective cohort study of 76 obese patients (mean body mass index [BMI] 38 kg/m2 and mean age 13 years) presenting to an obesity clinic between 2005 and 2010. For each patient, during 2 visits, FM was measured by bioelectrical impedance analysis and the following measures obtained: BMI, waist circumference, hip circumference, and neck circumference. Correlation coefficients and linear regression analyses were calculated to examine the relationship between each measure and FM. Results Change in BMI correlated better with change in FM than any other measure and had the strongest effect on change in FM ( P < .01, R2 = .887). The best regression model included BMI only ( R2 = .891); without BMI, the model was significantly worse ( R2 = .521). Discussion In the clinical management of obese children, BMI is an adequate measure of change in FM.
Philosophy as Therapy
Authors: Omelchenko Nikolay 
Published: April 2012

AbstractPhilosophy is deeply rooted in human nature. On the one hand, thinking of an infinite essence of the universe may actualize an infinite essence of humans themselves and thus root them in the Cosmos infinity. On the other hand, to think of infinity is to acquire the power of infinity, i.e., an infinite power. In short, thinking in terms of infinity fills us with infinity. Philosophy allows individuals to overstep the limits of the lived experience, transcends their Selves beyond daily occurrence. Obviously, just this human transcendence into metaphysical reality, into the world of essential relationships ensures a therapeutic effect of philosophy.

AbstractThe present study characterized the homologous and heterologous immune response in type-I porcine reproductive and respiratory syndrome virus (PRRSV) infection. Two experiments were conducted: in experiment 1, eight pigs were inoculated with PRRSV strain 3262 and 84 days post-inoculation (dpi) they were challenged with either strain 3262 or strain 3267 and followed for the next 14 days (98 dpi). In experiment 2, eight pigs were inoculated with strain 3267 and challenged at 84 dpi as above. Clinical course, viremia, humoral response (neutralizing and non-neutralizing antibodies, NA) and virus-specific IFN-γ responses (ELISPOT) were evaluated all throughout the study. Serum levels of IL-1, IL-6, IL-8, TNF-α and TGF-β were determined (ELISA) after the second challenge. In experiment 1 primo-inoculation with strain 3262 induced viremia of ≤ 28 days, low titres of homologous NA but strong IFN-γ responses. In contrast, strain 3267 induced longer viremias (up to 56 days), higher NA titres (≤ 6 log2) and lower IFN-γ responses. Inoculation with 3267 produced higher serum IL-8 levels. After the re-challenge at 84 dpi, pigs in experiment 1 developed mostly a one week viremia regardless of the strain used. In experiment 2, neither the homologous nor the heterologous challenge resulted in detectable viremia although PRRSV was present in tonsils of some animals. Homologous re-inoculation with 3267 produced elevated TGF-β levels in serum for 7–14 days but this did not occur with the heterologous re-inoculation. In conclusion, inoculation with different PRRSV strains result in different virological and immunological outcomes and in different degrees of homologous and heterologous protection.

Abstract
The Extradomain A from fibronectin (EDA) has an immunomodulatory role as fusion protein with viral and tumor antigens, but its effect when administered with bacteria has not been assessed. Here, we investigated the adjuvant effect of EDA in mice immunizations against Salmonella enterica subspecies enterica serovar Enteritidis (Salmonella Enteritidis). Since lipopolysaccharide (LPS) is a major virulence factor and the LPS O-polysaccharide (O-PS) is the immunodominant antigen in serological diagnostic tests, Salmonella mutants lacking O-PS (rough mutants) represent an interesting approach for developing new vaccines and diagnostic tests to differentiate infected and vaccinated animals (DIVA tests). Here, antigenic preparations (hot-saline extracts and formalin-inactivated bacterins) from two Salmonella Enteritidis rough mutants, carrying either intact (SEΔwaaL) or deep-defective (SEΔgal) LPS-Core, were used in combination with EDA. Biotinylated bacterins, in particular SEΔwaaL bacterin, decorated with EDAvidin (EDA and streptavidin fusion protein) improved the protection conferred by hot-saline or bacterins alone and prevented significantly the virulent infection at least to the levels of live attenuated rough mutants. These findings demonstrate the adjuvant effect of EDAvidin when administered with biotinylated bacterins from Salmonella Enteritidis lacking O-PS and the usefulness of BEDA-SEΔwaaL as non-live vaccine in the mouse model.
French-language version of the World Health Organization quality of life spirituality, religiousness and personal beliefs instrument

Published: April 2012

Abstract

Background
A valid assessment of spirituality and religiousness is necessary for clinical and research purposes. We developed and assessed the validity of a French-language version of the World Health Organization Quality of Life Spirituality, Religiousness and Personal Beliefs Instrument (WHOQOL-SRPB).

Methods
The SRPB was translated into French according to the methods recommended by the WHOQOL group. An Internet survey was conducted in 561 people in 2010, with follow-up 2 weeks later (n = 231, 41%), to assess reliability, factor structure, social desirability bias and construct validity of this scale. Tests were performed based on item-response theory.

Results
A modal score of 1 (all answers=”not at all”) was observed for Faith (in 34% of participants), Connectedness (27%), and Spiritual Strength (14%). All scales had test-retest reliability coefficients ≥0.7. Cronbach’s alpha coefficients were high for all subscales (0.74 to 0.98) and very high (>0.9) for three subscales (Connectedness, Spiritual Strength and Faith). Scores of Faith, Connectedness, Spiritual Strength and Meaning of Life were higher for respondents with religious practice than for those who had no religious practice. No association was found between SRPB and age or sex. The Awe subscale had a low information function for all levels of the Awe latent trait and may benefit from inclusion of an additional item.

Conclusions
The French language version of the SRPB retained many properties of the original version. However, the SRPB could be improved by trimming redundant items. The strength of SRPB relies on its multinational development and validation, allowing for cross-cultural comparisons.
Hypoglycemia associated with L-asparaginase in acute lymphoblastic leukemia treatment: a case report
Authors: Tanaka Ryuma , Osumi Tomoo , Miharu Masashi , Ishii Tomohiro , Hasegawa Tomonobu , Takahashi Takao , Shimada Hiroyuki 
Published: April 2012

Abstract
A patient with acute lymphoblastic leukemia repeatedly developed hypoglycemia during chemotherapy. Comparison of serum glucose trends between chemotherapy with and without L-asparaginase (L-Asp) demonstrated a strong association between L-Asp and hypoglycemia. Critical blood sampling during hypoglycemia indicated hyperinsulinism, suggesting that L-Asp induced hypoglycemia in the patient through inappropriate insulin secretion. Identification of hypoglycemia as an adverse effect will enable clinicians to understand and develop appropriate strategies for L-Asp use in chemotherapy regimens.
The generation of chromosomal deletions to provide extensive coverage and subdivision of the Drosophila melanogaster genome
Authors: Cook R Kimberley , Christensen Stacey J , Deal Jennifer A , Coburn Rachel A , Deal Megan E , Gresens Jill M , Kaufman Thomas C , Cook Kevin R 
Published: April 2012

Abstract
Background
Chromosomal deletions are used extensively in Drosophila melanogaster genetics research. Deletion mapping is the primary method used for fine-scale gene localization. Effective and efficient deletion mapping requires both extensive genomic coverage and a high density of molecularly defined breakpoints across the genome.

Results
A large-scale resource development project at the Bloomington Drosophila Stock Center has improved the choice of deletions beyond that provided by previous projects. FLP-mediated recombination between FRT-bearing transposon insertions was used to generate deletions, because it is efficient and provides single-nucleotide resolution in planning deletion screens. The 793 deletions generated pushed coverage of the euchromatic genome to 98.4%. Gaps in coverage contain haplolethal and haplosterile genes, but the sizes of these gaps were minimized by flanking these genes as closely as possible with deletions. In improving coverage, a complete inventory of haplolethal and haplosterile genes was generated and extensive information on other haploinsufficient genes was compiled. To aid mapping experiments, a subset of deletions was organized into a Deficiency Kit to provide maximal coverage efficiently. To improve the resolution of deletion mapping, screens were planned to distribute deletion breakpoints evenly across the genome. The median chromosomal interval between breakpoints now contains only nine genes and 377 intervals contain only single genes.

Conclusions
Drosophila melanogaster now has the most extensive genomic deletion coverage and breakpoint subdivision as well as the most comprehensive inventory of haploinsufficient genes of any multicellular organism. The improved selection of chromosomal deletion strains will be useful to nearly all Drosophila researchers.
Money-Back Guarantees: Helping the Low-Quality Retailer
Authors: McWilliams Bruce 
Published: April 2012

Existing literature, based on signaling theory, suggests that money-back guarantees (MBGs) will be utilized by high-quality firms, where high quality is defined as a low likelihood of product return. However, in today's world, MBGs are ubiquitous among major retailers, even when the likelihood of product return varies greatly between them. To understand this phenomenon, we explore a competitive environment between high- and low-quality retailers where consumers are fully informed and risk neutral, and retailers realize a salvage value for returned products. When MBGs are profitable, under continuous demand it is Nash equilibrium for both retailers to offer MBGs, and the low-quality retailer gains while the high-quality retailer loses relative to when MBGs are not offered. In contrast, if demand is lumpy, retailers can act monopolistically over their respective market segments, allowing both retailers to gain from MBGs, although the low-quality retailer still gains more.

Working When No One Is Watching: Motivation, Test Scores, and Economic Success
Authors: Segal Carmit 
Published: April 2012

This paper provides evidence that scores on simple, low-stakes tests are associated with future economic success because the scores also reflect test takers' personality traits associated with their level of intrinsic motivation. To establish this, I use the coding speed test that was administered without incentives to participants in the National Longitudinal Survey of Youth (NLSY). I show that, controlling for cognitive ability, the coding speed scores are correlated with future earnings of male NLSY participants. I provide evidence that the coding speed scores relate to intrinsic motivation. I show that the scores of the highly motivated, though less educated, group (potential recruits to the U.S. military), are higher than the NLSY participants' scores. I use controlled experiments to show directly that intrinsic motivation is an important component of the unincentivized coding speed scores and that it relates to test takers' personality traits. This paper was accepted by Teck Ho, behavioral economics.
Does Attention Constrain Developmental Trajectories in Fragile X Syndrome? A 3-Year Prospective Longitudinal Study
Authors: Cornish Kim , Cole Victoria , Longhi Elena , Karmiloff-Smith Annette , Scerif Gaia 
Published: April 2012

Abstract
Basic attentional processes and their impact on developmental trajectories in fragile X syndrome were assessed in a 3-year prospective study. Although fragile X syndrome is a monogenic X-linked disorder, there is striking variability in outcomes even in young boys with the condition. Attention is a key factor constraining interactions with the environment, so it is a perfect candidate to predict trajectories in cognitive and behavioral outcomes. In this study, 48 boys with fragile X syndrome were assessed 3 times over 24 months. Although nonverbal IQ declined, there were significant improvements in nonverbal growth scores and in cognitive attention. In contrast, behavioral difficulties (i.e., autistic symptomatology, hyperactivity–inattention) remained stable over this time frame. Attentional markers in the visual and auditory modalities predicted intellectual abilities and classroom behavior, whereas auditory markers alone predicted autistic symptomatology.
Do Autistic Symptoms Persist Across Time? Evidence of Substantial Change in Symptomatology Over a 3-year Period in Cognitively Able Children With Autism
Authors: Pellicano Elizabeth 
Published: April 2012

Abstract
This study investigated the extent and nature of changes in symptomatology in cognitively able children with autism over a 3-year period. Thirty-seven children diagnosed with an autism spectrum condition involved in an earlier study (M age  =  5 years, 7 months) were followed and reassessed 3 years later (M age  =  8 years, 4 months). Scores on the Social Communication Questionnaire (SCQ; M. Rutter, A. Bailey, & C. Lord, 2003) decreased significantly over time in all symptom domains but especially in the social domain, and correlational findings suggested the presence of 2 distinct developmental trajectories—social communication and repetitive behaviors—that interact across time. Furthermore, 7 children (19% of sample) made substantial changes to the extent that they failed to meet criteria on diagnostic instruments (the Autism Diagnostic Observation Schedule—Generic [ADOS-G; C. Lord, M. Rutter, P. C. DiLavore, & S. Risi, 1999] and the SCQ) 3 years later. Children showing diagnostic discontinuity were distinguishable from those who fulfilled ADOS-G criteria only in terms of the age at which they began receiving intervention. The presence of a significant proportion of children showing considerable progress over the 3-year period challenges assumptions of diagnostic continuity and highlights the potential long-term benefits of early intervention.

Evaluation of Protective Gloves and Working Techniques for Reducing Hand‐arm Vibration Exposure in the Workplace: Matija MILOSEVIC, et al. Electrical and Computer Engineering Department, Ryerson University, Canada—ObjectivesOperation of handheld power tools results in exposure to hand‐arm vibrations, which over time lead to numerous health complications. The objective of this study was to evaluate protective equipment and working techniques for the reduction of vibration exposure.MethodsVibration transmissions were recorded during different work techniques: with one‐ and two‐handed grip, while wearing protective gloves (standard, air and anti‐vibration gloves) and while holding a foam‐covered tool handle. The effect was examined by analyzing the reduction of transmitted vibrations at the wrist. The vibration transmission was recorded with a portable device using a triaxial accelerometer.ResultsThe results suggest large and significant reductions of vibration with appropriate safety equipment. Reductions of 85.6% were achieved when anti‐vibration gloves were used.ConclusionsOur results indicated that transmitted vibrations were affected by several factors and could be measured and significantly reduced.
A Comparative Study on Substituted Polyanilines for Supercapacitors

Published: April 2012

ABSTRACTThe effect of two substituent groups, ortho-methoxy (-OCH3) and methyl (-CH3) in aniline, have been studied for supercapacitor applications. The polyaniline (PANI), poly (o-anisidine) (POA) and poly (o-toluidine) (POT) have been synthesized by oxidative polymerization method, and characterized by Cyclic Voltammetry (CV), UV–visible spectroscopy, Raman spectroscopy, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) techniques. The specific capacitance, charging/discharging and electrochemical impedance characteristics of the supercapacitor fabricated using PANI, POA, as well as POT electrodes are evaluated in 2M H2SO4electrolytic media. The highest specific capacitance of 400 F/g is calculated for PANI, whereas, POA and POT have exhibited 360 F/g and 325 F/g capacitance in supercapacitor studies.
