« Faire le beau chez soi » : la part du corps dans l'aménagement et la décoration des espaces du quotidien
Authors: Beldjerd Sofian 
Published: May 2011

Résumé Le corps sensible joue un rôle central dans les processus d’appropriation des espaces du quotidien. L’enquête empirique menée sur la mise en forme, l’usage et l’appréciation de territoires personnels (domestiques et professionnels) donne à voir de nombreux dialogues entre les sensations et les sentiments, l’agréable et le beau. Après avoir mis en évidence les enjeux distincts (instrumentaux, hédoniques et formalistes) caractérisant l’appropriation corporelle de ces environnements (l’« aisance », le « confort » et la « beauté »), il s’agit de montrer que le corps habitant, contraint, voire dressé, ne se trouve pas seulement enjoint de « faire le beau », comme on l’attendrait d’un animal. Il se montre en effet tout autant capable de faire le beau, c’est-à-dire d’alimenter des mises en forme et des appréciations des espaces du quotidien qui relèvent d’une esthétique pleinement formaliste.
Wavefront-Optimized Ablation Versus Topography-Guided Customized Ablation in Myopic LASIK: Comparative Study of Higher Order Aberrations
Authors: El Awady Hatem E. , Ghanem Asaad A. , Saleh Sameh M. 
Published: May 2011

BACKGROUND AND OBJECTIVE:
To compare the outcomes of wavefront-optimized ablation and topography-guided ablation in fellow eyes of patients undergoing laser in situ keratomileusis (LASIK) for myopia.

PATIENTS AND METHODS:
This prospective study included 84 patients who underwent LASIK in both eyes: wavefront-optimized ablation in one eye (group I) and topography-guided ablation in the fellow eye (group II). The Moria2 microkeratome with a 110 single-use head (Moria, Antony, France) was used to create a superior hinged flap and the Allegretto Wave Excimer Laser (Alcon/Wavelight Light Laser Technologie GmbH, Erlangen, Germany) for photoablation. The Allegretto wave analyzer was used to measure the ocular aberrations before and 6 months after LASIK. Refractive visual outcomes and ocular aberration changes were compared between the two treatment modalities.

RESULTS:

Six months postoperatively, the mean uncorrected visual acuity of group II was statistically better than that of group I (
P
= .02). Seventy percent of group I and 83% of group II achieved a postoperative spherical equivalent refraction of ±0.5 diopters. The postoperative total root-mean-square of higher order aberrations (HOAs) of group II was smaller than that of group I, but the difference was not statistically significant (
P
= .51). There was a decrease in most of the individual terms of HOAs in group II, but it was only statistically significant in Z
3
−1
(
P
= .04). The reverse occurred in group I, where most of the individual terms of HOAs increased, but it was not statistically significant. Significant improvement was only noted in Z
5
3
(
P
= .05) and Z
5
5
(
P
= .04).

CONCLUSION:
Both wavefront-optimized ablation and topography-guided ablation provided good refractive results, but the latter induced fewer HOAs.
Effect of MHC Class I Diversification on Influenza Epitope-Specific CD8+ T Cell Precursor Frequency and Subsequent Effector Function

Published: May 2011

Abstract
Earlier studies of influenza-specific CD8+ T cell immunodominance hierarchies indicated that expression of the H2Kk MHC class I allele greatly diminishes responses to the H2Db-restriced DbPA224 epitope (acid polymerase, residues 224–233 complexed with H2Db). The results suggested that the presence of H2Kk during thymic differentiation led to the deletion of a prominent Vβ7+ subset of DbPA224-specific TCRs. The more recent definition of DbPA224-specific TCR CDR3β repertoires in H2b mice provides a new baseline for looking again at this possible H2Kk effect on DbPA224-specific TCR selection. We found that immune responses to several H2Db- and H2Kb-restricted influenza epitopes were indeed diminished in H2bxk F1 versus homozygous mice. In the case of DbPA224, lower numbers of naive precursors were part of the explanation, though a similar decrease in those specific for the DbNP366 epitope did not affect response magnitude. Changes in precursor frequency were not associated with any major loss of TCR diversity and could not fully account for the diminished DbPA224-specific response. Further functional and phenotypic characterization of influenza-specific CD8+ T cells suggested that the expansion and differentiation of the DbPA224-specific set is impaired in the H2bxk F1 environment. Thus, the DbPA224 response in H2bxk F1 mice is modulated by factors that affect the generation of naive epitope-specific precursors and the expansion and differentiation of these T cells during infection, rather than clonal deletion of a prominent Vβ7+ subset. Such findings illustrate the difficulties of predicting and defining the effects of MHC class I diversification on epitope-specific responses.

Abstract
Differentiation of naive CD4 T cells into Th2 cells is accompanied by chromatin remodeling and increased expression of a set of Th2-specific genes, including those encoding Th2 cytokines. IL-4–mediated STAT6 activation induces high levels of transcription of GATA3, a master regulator of Th2 cell differentiation, and enforced expression of GATA3 induces Th2 cytokine expression. However, it remains unclear whether the expression of other Th2-specific genes is induced directly by GATA3. A genome-wide unbiased chromatin immunoprecipitation assay coupled with massive parallel sequencing analysis revealed that GATA3 bound to 1279 genes selectively in Th2 cells, and 101 genes in both Th1 and Th2 cells. Simultaneously, we identified 26 highly Th2-specific STAT6-dependent inducible genes by DNA microarray analysis-based three-step selection processes, and among them 17 genes showed GATA3 binding. We assessed dependency on GATA3 for the transcription of these 26 Th2-specific genes, and 10 genes showed increased transcription in a GATA3-dependent manner, whereas 16 genes showed no significant responses. The transcription of the 16 GATA3-nonresponding genes was clearly increased by the introduction of an active form of STAT6, STAT6VT. Therefore, although GATA3 has been recognized as a master regulator of Th2 cell differentiation, many Th2-specific genes are not regulated by GATA3 itself, but in collaboration with STAT6.
On the Geometry of the Moduli Space of Real Binary Octics
Authors: Chu Kenneth C. K. 
Published: May 2011

Abstract The moduli space of smooth real binary octics has five connected components. They para- metrize the real binary octics whose defining equations have 0, … , 4 complex-conjugate pairs of roots respectively. We show that each of these five components has a real hyperbolic structure in the sense that each is isomorphic as a real-analytic manifold to the quotient of an open dense subset of 5- dimensional real hyperbolic space by the action of an arithmetic subgroup of Isom. These subgroups are commensurable to discrete hyperbolic reflection groups, and the Vinberg diagrams of the latter are computed.
Personal Factors Predictive of Health-Related Lifestyles of Community-Dwelling Older Adults

Published: May 2011

Abstract
We explored personal factors that can predict health-related lifestyles of community-dwelling older adults. A convenience sample of 253 older adults was recruited to complete the Health Enhancement Lifestyle Profile (HELP), a comprehensive measure of health-promoting behaviors. Data were analyzed through univariate correlational/comparative statistics followed by stepwise multiple regression analysis to determine significant predictor variables for different aspects of health-related lifestyle. Personal health conditions, including the number of chronic diseases or impairments and self-rated health, were two strong predictors for the HELP (R2 = .571, p &lt; .0001). Demographic characteristics, including age, gender, race, education, and employment status, also demonstrated varied degrees of capability for predicting the different HELP scales (e.g., Exercise, Diet, Leisure). When developing individualized plans for older adults in community settings, occupational therapists should consider the clients’ strengths and vulnerabilities potentially derived from personal health factors and demographic attributes to yield more effective lifestyle interventions.
Structural capital, innovation capability, and size effect: An empirical study
Authors: Aramburu Nekane , Sáenz Josune 
Published: May 2011

AbstractThe aim of this paper is to analyze the impact of different organizational enablers – i.e. ‘structural capital’ – on the ideation stage of innovation processes from an ‘intellectual capital’ (IC) perspective. Considering company size as one of the most relevant contingent variables as regards organizational conditions, the moderator role of this variable is also examined. To gather information about the variables under study, a questionnaire has been designed and addressed to the CEOs of a set of 142 Spanish manufacturing firms with more than 50 employees and which carry out R&D activities. Structural equation modelling (SEM) based on partial least squares (PLS) has then been applied in order to test the hypotheses drawn from the research. The results obtained show the organizational components which exert the greatest impact on the ideation phase and, therefore, the priority aspects to work on, in order to enhance this particular dimension of the innovation capability.
Who initiates and who implements? A multi-stage, multi-agent model of organizational innovation
Authors: Sung Sun Young , Cho Dong-Sung , Choi Jin Nam 
Published: May 2011

AbstractInnovation researchers have typically focused on either the adoption or the implementation phase of organizational innovation. In the present study, we propose that four agents of innovation (i.e., top management, external environment, innovation, and employees) play distinct roles in the adoption and implementation stages, and that, together, they predict innovation outcomes. We test the phase-dependent process of organizational innovation using data drawn from intensive interviews with 40 executives of a consumer product company. A path analysis of 94 innovations introduced to the organization over the past 20 years indicates that there is a significant level of stability in innovation-driving dynamics. Particularly, top management and employees tend to remain heavily involved in the implementation of an innovation if they played an important role in adopting it. The four agents of innovation play different roles in accruing benefits from the innovation. The results also suggest that employees tend to produce positive innovation outcomes when they have been involved in the innovation from the very beginning and are thus responsible for its adoption. The present study makes a distinct contribution to the literature by exploring the multi-stage, unfolding processes of organizational innovation.
Coping with boycotts: An analysis and framework
Authors: Shebil Saleh Al , Rasheed Abdul A , Al-Shammari Hussam 
Published: May 2011

AbstractIn recent years, consumer boycotts are increasingly being used by various activist groups to punish targeted countries. This paper develops an analytic framework to help managers formulate strategies to cope with country-of-origin-related consumer boycotts. Based on the two dimensions of brand–country association and boycott intensity, we propose four possible strategies. We discuss spillover effects wherein certain firms become unintended victims of boycotts due to misperceptions about their nationality. Also discussed are economic opportunities that boycotts present to potential new entrants.
Live Showups and Their Influence on a Subsequent Video Line‐up
Authors: Valentine Tim , Davis Josh P , Memon Amina , Roberts Andrew 
Published: May 2011

SummaryA live showup (known as a street identification in the UK) allows the perpetrator to be identified shortly after a street crime. If the suspect disputes the identification, a video line‐up often ensues. Four experiments examined the reliability of live showups and their influence on a subsequent video line‐up using realistic procedures and conditions. Similar proportions of culprits and innocent suspects were identified from live showups and video line‐ups. Both culprits and innocent suspects previously identified were likely to be identified again in a subsequent line‐up, with delays from a few minutes to a month. Only a weak effect of clothing bias was observed. There was strong evidence of commitment to a previous identification but no reliable evidence of source monitoring errors. The results suggest that a live showup is not less fair than a line‐up, but the use of repeated identification procedures introduces an unfair bias against innocent suspects.

Published: May 2011

AbstractRice leaves with anisotropic sliding properties have the ability to directionally control the movement of water microdroplets. However, the realization of artificial anisotropic sliding biosurfaces has remained challenging. It is found, by a systematic investigation, that the height of 200‐μm‐width groove arrays on rice leaves reaches up to 45 μm, far greater than the smaller microgrooves that are widely adopted for the study of anisotropic wetting. A new model based on three‐level microstructures (macro/micro/nano) is developed to interpret the anisotropic sliding behavior. Moreover, artificial rice leaves with different macrogrooves are demonstrated by combining micro/nanostructures and macrogrooves, which are prepared by photolithography, PDMS imprinting, and micro/nanostructure coating. Sliding‐angle measurement further prove that the third‐level macrogroove arrays are the determining factor for anisotropic sliding. Finally, a new testing method, curvature‐assisted droplet oscillation (CADO), is developed to quantitatively reveal the anisotropic dynamic behavior of biomimetic rice‐leaf‐like surfaces.
Asymmetric Aza‐Morita–Baylis–Hillman‐Type Reactions: The Highly Enantioselective Reaction between Unmodified α,β‐ Unsaturated Aldehydes and N‐Acylimines by Organo‐co‐catalysis

Published: May 2011

AbstractThe highly enantioselective organo‐co‐catalytic aza‐Morita–Baylis–Hillman (MBH)‐type reaction between N‐carbamate‐protected imines and α,β‐unsaturated aldehydes has been developed. The organic co‐catalytic system of proline and 1,4‐diazabicyclo[2.2.2]octane (DABCO) enables the asymmetric synthesis of the corresponding N‐Boc‐ and N‐Cbz‐protected β‐amino‐α‐alkylidene‐aldehydes in good to high yields and up to 99% ee. In the case of aza‐MBH‐type addition of enals to phenylprop‐2‐ene‐1‐imines, the co‐catalytic reaction exhibits excellent 1,2‐selectivity. The organo‐co‐catalytic aza‐MBH‐type reaction can also be performed by the direct highly enantioselective addition of α,β‐unsaturated aldehydes to bench‐stable N‐carbamate‐protected α‐amidosulfones to give the corresponding β‐amino‐α‐alkylidene‐aldehydes with up to 99% ee. The organo‐co‐catalytic aza‐MBH‐type reaction is also an expeditious entry to nearly enantiomerically pure β‐amino‐α‐alkylidene‐amino acids and β‐amino‐α‐alkylidene‐lactams (99% ee). The mechanism and stereochemistry of the chiral amine and DABCO co‐catalyzed aza‐MBH‐type reaction are also discussed.
N‐Alkylation of Amines with Alcohols Catalyzed by a Water‐Soluble Cp*Iridium Complex: An Efficient Method for the Synthesis of Amines in Aqueous Media

Published: May 2011

AbstractAn efficient and environmentally benign catalytic system for the synthesis of various organic amines catalyzed by the water‐soluble and air‐stable (pentamethylcyclopentadienyl)‐iridium‐ammine iod‐ ide complex, [Cp*Ir(NH3)3][I]2 (Cp*=pentamethylcyclopentadienyl), has been developed. A wide variety of secondary and tertiary amines were synthesized by the N‐alkylation reactions of theoretical equivalents of amines with alcohols in water under air without a base. The synthesis of cyclic amines was also achieved by the N‐alkylation of benzylamine with diols. Furthermore, the recycle use of the present water‐soluble Cp*Ir catalyst was accomplished.

AbstractWindow integrated photovoltaics for automotive and building applications are a promising market segment for organic solar modules. Besides semi‐transparency, window integrated applications require a reasonable transparency perception and good color rendering properties in order to be suitable for realistic scene illumination. Here, the transmitted light through semi‐transparent organic solar cells comprising the polymer/fullerene blend poly[(4,4'‐bis(2‐ethylhexyl)dithieno[3,2‐b:2',3'‐d]silole)‐2,6‐diyl‐alt‐(2,1,3‐benzothiadiazole)‐4,7‐diyl]: [6,6]‐phenyl C71‐butric acid methyl ester (PSBTBT:PC70BM) as active layer and a sputtered aluminum doped zinc oxide cathode were found to exhibit a color neutral perception for the human eye and very good color rendering properties. Moreover, the electrical cell properties allow for efficient energy harvesting with an overall power conversion efficiency η ≈ 3%.

Published: May 2011

AbstractThe goal of this longitudinal study was to assess the impact of economic change and increased market integration on subsistence strategies, living conditions, growth, and nutritional status of Ribeirinhos living in the rural Amazon, Brazil. Data on weight, height, skinfolds, and circumferences, as well as data on economic strategies and living conditions were collected from 469 individuals in 2002 and 429 in 2009. Of these, 204 individuals were measured on both occasions. Independent and paired t‐tests were used to identify changes in nutritional status over time in the larger sample and smaller, longitudinal subsample, respectively. Multiple linear regressions were used to examine the relationship between changes in economic/living conditions and nutritional status in the longitudinal subsample. Results indicate modest improvements in linear growth (HAZ) and among male children the observed increase was related to enrollment in the Brazilian conditional cash transfer program, Bolsa Família (P = 0.03). In terms of short‐term measures of nutritional status, we found a significant increase in ZTSF and a reduction in ZUMA in most age/sex groups. Among subadults, there was a negative relationship between ZUMA and access to electricity (P = 0.01) and positive relationship between ZUMA and the sale of the açaí fruit (P = 0.04). Significant changes in weight and BMI (P < 0.01) were found among adult females and both were negatively related to household cash income (P = 0.02 and P = 0.03, respectively). Despite significant changes in economic strategies and lifestyle, changes in nutritional status were modest which may be explained by increased food insecurity documented during this early stage of transition.

Indirect evidence for the genetic determination of short stature in African Pygmies

Published: May 2011

AbstractCentral African Pygmy populations are known to be the shortest human populations worldwide. Many evolutionary hypotheses have been proposed to explain this short stature: adaptation to food limitations, climate, forest density, or high mortality rates. However, such hypotheses are difficult to test given the lack of long‐term surveys and demographic data. Whether the short stature observed nowadays in African Pygmy populations as compared to their Non‐Pygmy neighbors is determined by genetic factors remains widely unknown. Here, we study a uniquely large new anthropometrical dataset comprising more than 1,000 individuals from 10 Central African Pygmy and neighboring Non‐Pygmy populations, categorized as such based on cultural criteria rather than height. We show that climate, or forest density may not play a major role in the difference in adult stature between existing Pygmies and Non‐Pygmies, without ruling out the hypothesis that such factors played an important evolutionary role in the past. Furthermore, we analyzed the relationship between stature and neutral genetic variation in a subset of 213 individuals and found that the Pygmy individuals' stature was significantly positively correlated with levels of genetic similarity with the Non‐Pygmy gene‐pool for both men and women. Overall, we show that a Pygmy individual exhibiting a high level of genetic admixture with the neighboring Non‐Pygmies is likely to be taller. These results show for the first time that the major morphological difference in stature found between Central African Pygmy and Non‐Pygmy populations is likely determined by genetic factors.

Ontogeny of limb proportions in late through final Jomon period foragers
Authors: Temple Daniel H. , Okazaki Kenji , Cowgill Libby W. 
Published: May 2011

AbstractThis study reports on developmental patterning in the intralimb indices of Late/Final Jomon period (4000–2300 BP) people. Jomon foragers represent the descendants of migrants from Northeast Asia, who arrived in the Japanese Islands around 20,000 BP. Among adults, Jomon brachial indices are elevated and similar to warm adapted, low latitude people, while crural indices are intermediate and similar to people from moderate latitudes. Two hypotheses regarding the development of intralimb indices among Jomon period foragers are tested: (1) intralimb indices of Jomon people maintain predicted ecogeographic relationships over ontogeny; (2) greater evolvability will be observed in the brachial index, while greater developmental constraint will be observed in the crural index. Changes in intralimb proportions in a Jomon skeletal growth series are compared to those in two contrasting samples: Inuit from Point Hope (cold adapted) and Nubians from Kulubnarti (warm adapted). A quadratic equation best describes the ontogeny of brachial and crural indices, with high indices in infancy followed by a decline in childhood and an increase in adolescence. Despite these shifts, ecogeographically predicted differences and similarities in the indices are maintained between samples throughout ontogeny. In addition, radial relative to humeral length is significantly less correlated than tibial relative to femoral length. These results suggest genetic conservation of intralimb indices over the course of development. However, radial and humeral lengths are less correlated than tibial and femoral lengths among Jomon subadults and adults, potentially suggesting greater evolvability of the brachial index and more developmental constraint on the crural index.
