High-Precision Phenotyping of Grape Bunch Architecture Using Fast 3D Sensor and Automation
Authors: Rist Florian , Herzog Katja , Mack Jenny , Richter Robert , Steinhage Volker , Töpfer Reinhard
Published: March 2018

Wine growers prefer cultivars with looser bunch architecture because of the decreased risk for bunch rot. As a consequence, grapevine breeders have to select seedlings and new cultivars with regard to appropriate bunch traits. Bunch architecture is a mosaic of different single traits which makes phenotyping labor-intensive and time-consuming. In the present study, a fast and high-precision phenotyping pipeline was developed. The optical sensor Artec Spider 3D scanner (Artec 3D, L-1466, Luxembourg) was used to generate dense 3D point clouds of grapevine bunches under lab conditions and an automated analysis software called 3D-Bunch-Tool was developed to extract different single 3D bunch traits, i.e., the number of berries, berry diameter, single berry volume, total volume of berries, convex hull volume of grapes, bunch width and bunch length. The method was validated on whole bunches of different grapevine cultivars and phenotypic variable breeding material. Reliable phenotypic data were obtained which show high significant correlations (up to r2 = 0.95 for berry number) compared to ground truth data. Moreover, it was shown that the Artec Spider can be used directly in the field where achieved data show comparable precision with regard to the lab application. This non-invasive and non-contact field application facilitates the first high-precision phenotyping pipeline based on 3D bunch traits in large plant sets.
Three-Dimensional Reconstruction from Single Image Base on Combination of CNN and Multi-Spectral Photometric Stereo
Authors: Lu Liang , Qi Lin , Luo Yisong , Jiao Hengchao , Dong Junyu
Published: March 2018

Multi-spectral photometric stereo can recover pixel-wise surface normal from a single RGB image. The difficulty lies in that the intensity in each channel is the tangle of illumination, albedo and camera response; thus, an initial estimate of the normal is required in optimization-based solutions. In this paper, we propose to make a rough depth estimation using the deep convolutional neural network (CNN) instead of using depth sensors or binocular stereo devices. Since high-resolution ground-truth data is expensive to obtain, we designed a network and trained it with rendered images of synthetic 3D objects. We use the model to predict initial normal of real-world objects and iteratively optimize the fine-scale geometry in the multi-spectral photometric stereo framework. The experimental results illustrate the improvement of the proposed method compared with existing methods.
The Historical Memory of American Presidents in the Mass Public
Authors: Cohen Jeffrey
Published: March 2018

This paper investigates public evaluations of past presidents. Since voters generally lack much historical knowledge, such evaluations are not useful indicators of the performance and effectiveness of presidents across history, unlike the greatness evaluations of experts, like historians and presidency scholars. Still, presidents may be concerned about how future generations of voters will think about them. These anticipations may then affect presidential behavior in office. This study uses a Rasmussen poll in 2007 that asked voters their assessment of all the past presidents, from George Washington through to George W. Bush. Results find that voters look upon past presidents more favorably as a larger number of voters have opinions about the president, presidents of the founding generation are looked upon more favorably, and the ratings of experts affect voters’ assessments of past presidents. The conclusion discusses the implications of the results and offers suggestions for future research.
Sustainability Reporting and Value Relevance of Financial Statements
Authors: Sutopo Bambang , Kot Sebastian , Adiati Arum , Ardila Lina
Published: March 2018

This study examines whether information about the winners of the Sustainability Reporting Award (SRA) contributes to the usefulness of the information in financial statements. This study used a sample consisting of 110 winners of SRA (SRA firms) and 110 companies that did not receive SRA (non-SRA firms) from 2008 to 2016. The study found that earnings per share (EPS), earnings per share change (EPSC), and book value per share (BVPS) are value-relevant information. Results of comparison between SRA firms and non-SRA firms show that the positive association between EPS and stock price (P) and the positive association of EPS with stock returns (R) for SRA firms are higher than that for the non-SRA firms. In addition, findings of this study indicate that EPSC is positively associated with R when EPSC and R are measured by Indonesian rupiah (IDR) instead of by percentage, and the positive association between EPSC and R for the SRA firms is higher than that for the non-SRA firms. Thus, the results are sensitive to measures of the variables. However, this study found that value relevance of BVPS for SRA firms is lower than for non-SRA firms. Implication of this study is that information about the winners of SRA contributes to the usefulness of financial statements, especially the information of EPS and EPSC.
Selecting Network-Level Project Sections for Sustainable Pavement Management in Texas
Authors: Kim Dae , Chi Seokho , Kim Janghwan
Published: March 2018

In recent years, the increasing gap between available funding and preservation needs has influenced district pavement engineers to select and prioritize projects to effectively use funding. However, currently, projects are often selected after an informal assessment, based on local conditions and local district engineers’ experience, in the absence of a statewide systematic process. The primary objective of this study is to determine network-level project sections for effective sustainable pavement management using logistic regression analysis. A large volume of inventory data, documented using pavement-management information systems (PMIS), was used to develop the logistic regression (LR) model for selecting candidate sections. The LR model was subsequently validated using a single 50/50 split sample method. The findings of this study will assist the Austin, Texas, USA district to select and evaluate candidate projects. Furthermore, the study will eventually contribute to improved efficiency in project selection and prioritization by reducing not only the amount of time necessary to review the district PMIS data to identify project candidates, but also the potential for human error.

Published: March 2018

This paper analyzed the evolution of climate data in the Rio Bravo Basin in Mexico from 1980–2009 and projects future climate conditions in this region. Then, the potential impacts of climate change on water resources for crops in the nine irrigation districts (IDs) of the Rio Bravo Basin were evaluated. Specifically, climate data on precipitation, maximum and minimum temperatures, and evapotranspiration from the baseline period of 1980–2009 were compared with projected climate conditions for 2015–2039, 2045–2069, and 2075–2099. The projections were based on two representative concentration pathways (RCPs) of greenhouse gases in the atmosphere (RCP4.5 and RCP8.5). Patterns in the behavior of the analyzed climate variables over the past ten decades were examined and compared to the projected evolution of these variables through to the end of the century. Overall, in the future, temperatures, rates of evapotranspiration, and crop water demand are expected to increase. Also, the future precipitation patterns of all IDs were modified under the considered scenarios. Finally, the IDs of Acuña-Falcón and Delicias will be the most impacted by climate changes, while Palestina will be the least affected.
MicroRNA-664 Targets Insulin Receptor Substrate 1 to Suppress Cell Proliferation and Invasion in Breast Cancer
Authors: Wu Liang , Li Yuefeng , Li Jingye , Ma Deliang
Published: March 2018

A large number of microRNAs (miRNAs) have been previously demonstrated to be dysregulated in breast cancer (BC), and alterations in miRNA expression may affect the initiation and progression of BC. This study showed that miR-664 expression was obviously reduced in BC tissues and cell
lines. Resumption of the expression of miR-664 attenuated the proliferation and invasion of BC cells. The molecular mechanisms underlying the inhibitory effects of BC cell proliferation and invasion by miR-664 were also studied. Insulin receptor substrate 1 (IRS1) was identified as a novel
and direct target of miR-664. In addition, siRNA-mediated silencing of IRS1 expression mimicked the suppressive effects of miR-664 overexpression in BC cells. Rescue experiments demonstrated that recovered IRS1 expression partially antagonized the inhibition of proliferation and invasion of
BC cells caused by miR-664 overexpression. Thus, miR-664 may serve as a tumor suppressor in BC by directly targeting IRS1. Moreover, miR-664 downregulation in BC may contribute to the occurrence and development of BC, suggesting that miR-664 may be a novel therapeutic target for patients with
BC.
Knockdown of Long Noncoding RNA ENST457720 Inhibits Proliferation of Non-Small Cell Lung Cancer Cells In Vitro and In Vivo
Authors: Yu Jia , Fang Qiyu , Meng Shuyan
Published: March 2018

Non-small cell lung cancer (NSCLC) represents the leading cause of cancer-related mortality worldwide. More and more reports have identified important roles for long noncoding RNAs (lncRNAs) in cancer development. ENST457720 expression was upregulated in lung adenocarcinoma in a microarray-based lncRNA screen. We determined the expression levels of ENST457720 in NSCLC tissues with quantitative real-time PCR and then studied their clinical significance. We explored the biological significance of ENST457720 with gain- and loss-of-function analyses in vitro and in vivo. In this study, ENST457720 was expressed at higher levels in NSCLC tissues than in paired normal tissues. Higher ENST457720 expression was associated with larger tumor sizes, lymph node metastasis, and advanced TNM stage. ENST457720 silencing suppressed NSCLC cell proliferation in vitro and in vivo. Moreover, ENST457720 knockdown inhibited NSCLC invasion and reversed the epithelial-to-mesenchymal transition. ENST457720 promoted NSCLC proliferation and invasion, which may be a novel potential therapeutic target for NSCLC.
Polarization Properties and Magnetic Field Structures in the High-mass Star-forming Region W51 Observed with ALMA

Published: March 2018

We present the first ALMA dust polarization observations toward the high-mass star-forming regions W51 e2, e8, and W51 North in Band 6 (230 GHz) with a resolution of about

(∼5 mpc). Polarized emission in all three sources is clearly detected and resolved. Measured relative polarization levels are between 0.1% and 10%. While the absolute polarization shows complicated structures, the relative polarization displays the typical anticorrelation with Stokes I, although with a large scatter. Inferred magnetic (B) field morphologies are organized and connected. Detailed substructures are resolved, revealing new features such as comet-shaped B-field morphologies in satellite cores, symmetrically converging B-field zones, and possibly streamlined morphologies. The local B-field dispersion shows some anticorrelation with the relative polarization. Moreover, the lowest polarization percentages together with largest dispersions coincide with B-field convergence zones. We put forward

, where ω is the measurable angle between a local B-field orientation and local gravity, as a measure of how effectively the B field can oppose gravity. Maps of

for all three sources show organized structures that suggest a locally varying role of the B field, with some regions where gravity can largely act unaffectedly, possibly in a network of narrow magnetic channels, and other regions where the B field can work maximally against gravity.
An Empirical Mass Function Distribution
Authors: Murray S. G. , Robotham A. S. G. , Power C.
Published: March 2018

The halo mass function, encoding the comoving number density of dark matter halos of a given mass, plays a key role in understanding the formation and evolution of galaxies. As such, it is a key goal of current and future deep optical surveys to constrain the mass function down to mass scales that typically host

galaxies. Motivated by the proven accuracy of Press–Schechter-type mass functions, we introduce a related but purely empirical form consistent with standard formulae to better than 4% in the medium-mass regime,

. In particular, our form consists of four parameters, each of which has a simple interpretation, and can be directly related to parameters of the galaxy distribution, such as

. Using this form within a hierarchical Bayesian likelihood model, we show how individual mass-measurement errors can be successfully included in a typical analysis, while accounting for Eddington bias. We apply our form to a question of survey design in the context of a semi-realistic data model, illustrating how it can be used to obtain optimal balance between survey depth and angular coverage for constraints on mass function parameters. Open-source Python and R codes to apply our new form are provided at http://mrpy.readthedocs.org  and https://cran.r-project.org/web/packages/tggd/index.html  respectively.
Simulating the Galaxy Cluster “El Gordo”: Gas Motion, Kinetic Sunyaev–Zel’dovich Signal, and X-Ray Line Features
Authors: Zhang Congyao , Yu Qingjuan , Lu Youjun
Published: March 2018

The massive galaxy cluster “El Gordo” (ACT-CL J0102–4915) is a rare merging system with a high collision speed suggested by multi-wavelength observations and theoretical modeling. Zhang et al. propose two types of mergers, a nearly head-on merger and an off-axis merger with a large impact parameter, to reproduce most of the observational features of the cluster using numerical simulations. The different merger configurations of the two models result in different gas motion in the simulated clusters. In this paper, we predict the kinetic Sunyaev–Zel’dovich (kSZ) effect, the relativistic correction of the thermal Sunyaev–Zel’dovich (tSZ) effect, and the X-ray spectrum of this cluster, based on the two proposed models. We find that (1) the amplitudes of the kSZ effect resulting from the two models are both on the order of ΔT/T ∼ 10−5; but their morphologies are different, which trace the different line-of-sight velocity distributions of the systems; (2) the relativistic correction of the tSZ effect around 240 GHz can be possibly used to constrain the temperature of the hot electrons heated by the shocks; and (3) the shift between the X-ray spectral lines emitted from different regions of the cluster can be significantly different in the two models. The shift and the line broadening can be up to ∼25 eV and 50 eV, respectively. We expect that future observations of the kSZ effect and the X-ray spectral lines (e.g., by ALMA, XARM) will provide a strong constraint on the gas motion and the merger configuration of ACT-CL J0102–4915.

Diagnostics of polarized emission provide us with valuable information on the Galactic magnetic field and the state of turbulence in the interstellar medium, which cannot be obtained from synchrotron intensity alone. In Paper I, we derived polarization diagnostics that are rotationally and translationally invariant in the Q–U plane, similar to the polarization gradient. In this paper, we apply these diagnostics to simulations of ideal magnetohydrodynamic turbulence that have a range of sonic and Alfvénic Mach numbers. We generate synthetic images of Stokes Q and U for these simulations for the cases where the turbulence is illuminated from behind by uniform polarized emission and where the polarized emission originates from within the turbulent volume. From these simulated images, we calculate the polarization diagnostics derived in Paper I for different lines of sight relative to the mean magnetic field and for a range of frequencies. For all of our simulations, we find that the polarization gradient is very similar to the generalized polarization gradient and that both trace spatial variations in the magnetoionic medium for the case where emission originates within the turbulent volume, provided that the medium is not supersonic. We propose a method for distinguishing the cases of emission coming from behind or within a turbulent, Faraday rotating medium and a method to partly map the rotation measure of the observed region. We also speculate on statistics of these diagnostics that may allow us to constrain the physical properties of an observed turbulent region.

We present an unbiased large-scale (9 deg2) CN (N = 1–0) and C18O (J = 1–0) survey of Cygnus-X conducted with the Nobeyama 45 m Cygnus-X CO survey. CN and C18O are detected in various objects toward the Cygnus-X North and South (e.g., DR17, DR18, DR21, DR22, DR23, and W75N). We find that CN/C18O integrated intensity ratios are systematically different from region to region, and are especially enhanced in DR17 and DR18, which are irradiated by the nearby OB stars. This result suggests that CN/C18O ratios are enhanced via photodissociation reactions. We investigate the relation between the CN/C18O ratio and strength of the UV radiation field. As a result, we find that CN/C18O ratios correlate with the far-UV intensities, G
0. We also find that CN/C18O ratios decrease inside molecular clouds, where the interstellar UV radiation is reduced due to the interstellar dust extinction. We conclude that the CN/C18O ratio is controlled by the UV radiation, and is a good probe of photon-dominated regions.

Published: March 2018

O desenvolvimento de uma localidade corresponde ao crescimento econômico e à melhoria dos aspectos sociais, a exemplo da organização social e de seus elementos como confiança, normas e redes. Todos esses fatores relacionam-se ao capital social, que facilita a coordenação e cooperação para o alcance de benefícios dos indivíduos em coletividade. No centro desse debate, está o papel dos agentes sociais e de outras formas de sociabilidade egressas do próprio território, tais como: a participação em organizações, grupos e redes que proporcionam aos seus membros um capital coletivo. Este, por sua vez, criado e sustentado por trocas compartilhadas. Com base nesses aspectos, o objetivo do artigo é discutir o protagonismo dos agentes sociais do agronegócio no município de Uruçuí, e o seu potencial para influenciar o desenvolvimento no município sob uma perspectiva mais abrangente que a econômica, por meio do capital social. Identificaram-se possibilidades e também limites e desafios.

One-year Predictors of Presenteeism in Workers with Rheumatoid Arthritis: Disease-related Factors and Characteristics of General Health and Work
Authors: Boot Cécile R.L. , de Wind Astrid , van Vilsteren Myrthe , van der Beek Allard J. , van Schaardenburg Dirkjan , Anema Johannes R.
Published: March 2018

Objective.

Rheumatoid arthritis (RA) affects adults of working age and leads to productivity losses because of presenteeism that results from limitations while at work. The aim of our study was to gain insight into disease-related factors, general health, and work characteristics as predictors of presenteeism in workers with RA.

Methods.

Workers with RA (n = 150) recruited by rheumatologists completed questionnaires at baseline and after 1 year. Medical information was retrieved from patient records. Presenteeism was measured by the Work Limitations Questionnaire. Disease [28-joint Disease Activity Score (DAS28), Health Assessment Questionnaire (HAQ), pain, fatigue], general health (mental, physical, deterioration of health), and work characteristics (work instability, social support, workload) were assessed as predictors of presenteeism after 1 year using linear regression analyses.

Results.

Presenteeism was 4.0 h over a 2-week period based on an average work week of 28.7 hours. More RA-related disability (HAQ; B = −1.20, 95% CI −2.12 to −0.28), poorer mental health (B = −0.04, 95% CI −0.08 to −0.01), and health deterioration over a 1-year period (B: −0.02, 95% CI −0.04 to −0.01) were associated with more presenteeism. Work characteristics were not associated with presenteeism.

Conclusion.

Disease-related factors and general health characteristics were significantly associated with presenteeism at 1-year followup, although the effects of the general health characteristics were considered not to be relevant. To reduce presenteeism and improve functioning at work, it is important to pay attention to reducing RA-related disability in addition to reducing disease activity. A broader perspective is needed and should also take into account the level of RA-related disability.

Vers un enracinement cosmopolite

Published: March 2018

Dans un livre désormais classique, le politiste américain Sydney Tarrow soulignait les ressources internes mobilisées par les militant·e·s engagé·e·s dans des causes transnationales, évoquant des formes de « cosmopolitisme enraciné ». En analysant le développement récent des circulations entre la France et le Québec, cet article montre, de manière symétrique, combien la comparaison internationale constitue une dimension de plus en plus fréquente, voire obligée, de pratiques sociales et politiques ancrées localement et/ou nationalement. Ainsi, et en dépit des multiples différences qui caractérisent ces sociétés si souvent rapprochées, la France et le Québec tendent à former un vis-à-vis comparatif , dont les ressortissant·e·s, chercheur·e·s mais aussi et surtout fonctionnaires, militant·e·s, élu·e·s, journalistes – tendent à se comparer. Défendant une épistémologie réflexive, cet article invite donc les comparatistes savants à interroger leurs propres méthodes, en tenant compte des usages ordinaires de la comparaison parmi leurs enquêté·e·s (qui se comparent, autant qu’on les compare), ainsi que des enjeux internes de ce comparatisme désormais généralisé.
« Au nom du peuple » ? Circulations du « populisme » et représentations du populaire au Québec
Authors: Mazot-Oudin Antoine
Published: March 2018

Les usages savants et médiatiques de la notion de « populisme » apparaissent au début des années 2000 au Québec, deux décennies plus tard qu’en France. Les auteurs qui utilisent cette notion pour analyser la scène électorale québécoise naviguent entre des références tantôt françaises, tantôt nord-américaines, mais décrivent un « peuple » aux propriétés sociales bien distinctes des groupes sociaux visés par ce terme en France. Comprendre les dynamiques de circulation, de traduction et de réception de la notion de « populisme » au Québec nécessite de se pencher simultanément sur les trajectoires des intellectuels impliqués dans ces processus et sur les spécificités de ce contexte d’énonciation. La moindre importance de la sociologie politique des groupes sociaux au Québec influence notamment les manières de (se) représenter le populaire à l’aide de cette catégorie.
Les « anciennes » élites économiques et le changement de régime en Tunisie : de l’incertitude vers la consolidation politico-économique des positions
Authors: Kchouk Bilel
Published: March 2018

Les élites économiques du régime de Ben Ali ont été organiquement liées à son clan et à son système de domination politique. Malgré la décapitation puis l’implosion de ce système, ces acteurs ont réussi à sauver leur position et leur patrimoine. Cette recherche s’intéresse aux stratégies et aux mécanismes ayant permis la survie et le replacement de ces acteurs. En prenant appui sur une série d’entrevues avec des acteurs stratégiques des deux régimes qui se succèdent, notre enquête démontre que c’est en combinant l’attentisme durant la crise, la saisie des nouvelles opportunités économiques et l’entrisme politique post-Ben Ali que ses élites économiques ont pu survivre au changement de régime et surtout se repositionner comme des acteurs incontournables.
Free jazz made in France. Contribution à l’étude des dynamiques de radicalisation dans la France des années 1960 et 1970
Authors: Voilliot Christophe
Published: March 2018

Cet article est une contribution à l’analyse des phénomènes de surenchère à la radicalité à partir de l’étude des musiciens qui se sont réclamés de l’esthétique du free jazz en France. Si l’assignation à la radicalité de ce courant musical est d’abord le fruit d’un transfert et d’une réception complexe et décalée d’une forme musicale apparue aux États-Unis par ses commentateurs français, elle fait aussi écho à l’engagement politique de musiciens dans le contexte du « mai » français et du désengagement lié au reflux militant des années 1970. En les restituant, à partir de témoignages et de l’étude de la presse musicale et militante de l’époque, cet article tente de reconstruire une dynamique de radicalisation à la fois originale et partiellement oblitérée.

Preceptor Education for Specialty Community-Based Nurses: A Pre- and Postevaluation
Authors: Mitchell Creina , Ridgway Lael , Sheeran Leanne
Published: March 2018

Background:

Quality preceptorship is an integral aspect of nursing education. Evidence suggests that preceptor education programs can be designed to support RNs in their capacity as preceptors. Little has been reported on the effectiveness of preceptor programs for community-based nurses who provide primary health care for preschool children and their families.

Method:

The project evaluated the effectiveness of a 4-hour face-to-face tailored preceptor education program undertaken by 59 nurses in Victoria, Australia. Pre- and postsurveys were undertaken to evaluate the program.

Results:

Participants had improved understanding of the role of preceptor after the education program. They had increased confidence in their ability to give feedback, assess clinical skills, and use the clinical assessment tool. They were also surer of the standard of performance expected of students.

Conclusion:

A strategically designed preceptor program was effective in improving some preceptorship skills of community-based nurses who supervise postgraduate nursing students.

Published: March 2018

It is essential that nurses and midwives can understand and critically evaluate research to ensure the delivery of high-quality evidence-based care. Journal clubs are an educational method that helps to develop research capacity and assist with bridging the gap between research and clinical practice. To maintain competence and remain current with the latest evidence, a commitment to continuing professional education is required. This article describes how a successful journal club led to clinical nurses identifying a gap in their own practice, which resulted in a research project being conducted by the members of the journal club.

Published: March 2018

The current article discusses how and by whom family caregivers want to be supported in self-management when managing changes in behavior and mood of relatives with dementia and whether family caregivers consider eHealth a useful tool for self-management support. Four asynchronous online focus groups were held with 32 family caregivers of individuals with dementia. Transcripts of the online focus groups were analyzed using qualitative thematic analysis. Family caregivers need support from professionals or peers in the form of (a) information about dementia and its symptoms, (b) tips and advice on managing changes in behavior and mood, (c) opportunities to discuss experiences and feelings, and (d) appreciation and acknowledgement of caregiving. The opinions of family caregivers about self-management support through eHealth were also reported. Findings suggest a personal approach is essential to self-management support for family caregivers managing changes in behavior and mood of relatives with dementia. In addition, self-management support can be provided to some extent through eHealth, but this medium cannot replace personal contacts entirely.

Feasibility and Pilot Testing of a Mindfulness Intervention for Frail Older Adults and Individuals With Dementia
Authors: Kovach Christine R. , Evans Crystal-Rae , Sattell Lisa , Rosenau Kimberly , Gopalakrishnan Sandeep
Published: March 2018

Mindfulness interventions have been beneficial for healthy adults and individuals experiencing a stressful medical or mental health diagnosis. The purposes of the current study were to: (a) determine feasibility of mindfulness for older adults in long-term residential settings, and (b) examine differences in outcomes between a mindfulness and cognitive activity. The current study is the first mindfulness study to include individuals in moderate and severe stages of dementia, and included 36 individuals with a range of cognitive abilities. A crossover design was used, and the intervention was feasible for continued practice by individuals with cognitive impairment. Statistically significant short-term changes in agitation, discomfort, anger, and anxiety were found. Nighttime sleep did not improve, but participants slept less during the day. Long-term changes in outcomes were not found. Mindfulness may be useful in decreasing emotional reactivity and improving well-being of older adults in long-term care.

Targets:

Individuals with multiple chronic conditions, including cognitive impairment.

Intervention Description:

The Present in the Now (PIN) intervention is a mindfulness intervention with three components: attentional skill exercises, body awareness activities, and compassion meditation.

Mechanisms of Action:

Mindfulness acts to decrease emotional reactivity through cognitive and affective mechanisms of action and neural activation of the cingulate cortex, amygdala, and hippocampus.

Outcomes:

Agitation, affect, stress, sleep, discomfort, and communication of need.

= 45). Outcomes of interest included rehospitalization rates and hemoglobin A1C (A1C) for up to 1-year post hospital discharge. Rates of rehospitalization and A1C improved for older adults who received nurse-led inpatient DSME and homecare during transitions of care from hospital to home. Rehospitalization rates up to 90 days were decreased for the DSME plus homecare group (10%) compared to DSME only (20%) and usual care groups (26.7%) (
p
< 0.05). A decrease of −0.4 and −2.3 A1C units was observed for the DSME group and DSME plus homecare group, respectively, at 90 days. These results support a transitional care educational intervention for older adults with type 2 diabetes mellitus and obesity.

Targets:

Older adults with type 2 diabetes mellitus and obesity.

Intervention Description:

Transitional care intervention including diabetes self-management education and homecare.

Mechanisms of Action:

Inpatient diabetes education and homecare helps improve rates of rehospitalization and hemoglobin A1C during care transitions from hospital to home.

TEACHING VISUAL SCRIPTING IN BIM: A CASE STUDY USING A PANEL CONTROLLED BY SOLAR ANGLES
Authors: Kensek Karen M.
Published: March 2018

Programming and scripting can be used to activate a 3D parametric model to create a more intelligent and flexible building information model. There has been a trend in the building industry towards the use of visual scripting that allow users to create customized, flexible, and powerful programs without having to first learn how to write traditional code. Using visual scripting, users graphically interact with program elements instead of typing lines of text-based code. Nodes are created and virtually wired together; they can be numbers, sliders for adjusting values, operators and functions, list manipulation tools, graphic creators, and other types. Text based coding programs such as Python can also be used for the creation of custom nodes when greater flexibility is desired.

Examples from professional firms include scripts that help automate work in the office to increase efficiency and accuracy (e.g. create escape routes, renumber rooms by levels, create documentation), assist in form generation (e.g. parametric design of metal panels, rebar generation, coordination between Revit and Rhino), analyze BIM files (e.g. terminal airflow, visual loads and capacity), and provide analysis results (e.g. daylighting, thermal comfort, window optimization).

One can learn the basic steps of learning a visual programming language through the use of Dynamo within Autodesk Revit. The example used is for a façade component that changes based on the sun's altitude.
A SURVEY OF SOLAR ENVELOPE PROPERTIES USING SOLID MODELLING
Authors: Stasinopoulos Thanos N.
Published: March 2018

Solar envelope is a concept for regulating solar access in urban planning. It is a roof-like imaginary surface over a given piece of land that controls the maximum allowed building height in order to avoid casting shadows on the neighbours during a specific period.

The volume of solar envelopes regulates building density, depending on geometric attributes and time (plot size and proportions, orientation, ground slope, latitude, duration of insolation). This work compares the effect of such factors on the size of solar envelopes on a variety of land parcels, individually or in groups. Repeated applications of solid modelling are used to calculate in each case the values of ‘Solar Volume Coefficient’, i.e. the volume of a solar envelope per unit of its base as a measure for comparisons.

Results show the influence of the various factors affecting the geometry of solar envelopes. Among other findings, it is also shown that solar envelopes generate urban densities lower than conventional urban regulations. The total volume of solar envelopes over an area ( ‘Solar Building Potential’) can be increased by raising the reference level of solar envelopes ( ‘shadow fence’ or ‘solar fence’). Lower urban densities are compensated by facilitating solar applications, as well as by enhancing daylight, ventilation, and vistas in the urban context, thus creating new ‘solar cityscapes’ exemplified here on existing street patterns.
Subprimes, signaux faibles et véridiction
Authors: de Oliveira-Verger Christelle
Published: March 2018

La crise des subprimes débute en 2007 aux États-Unis par une crise immobilière liée aux très nombreux impayés des prêts subprimes. L’auteure étudie un événement marquant de ce début de crise, se déroulant dans un contexte économique « normal » : la mise en difficulté de la BNP par les crédits subprimes et son traitement dans la presse. Cela pour comprendre, au travers de la problématique de la véridiction, la volonté de non prise en compte de certains signaux annonciateurs de cette crise et leur impact réel sur le devenir du système, contribuant alors à provoquer une crise financière mondiale.
« Publiquement privé » et le contexte
Authors: Kwok Choon Mary Jane
Published: March 2018

L’auteure analyse les attitudes et les perceptions de la vie privée des jeunes adultes au cours de leurs usages des réseaux socionumériques. Son étude montre qu’il existe des tensions entre les formes de visibilité en tant que reconnaissance et celles qui sont déployées par les surveillants pour exercer le contrôle social. Ces jeunes adultes expérimentent la collision et la collusion de contexte. Il importe de prendre en compte la dimension sociale et contextuelle de la vie privée dans la constitution des politiques de confidentialité.
De la performance à la reconnaissance
Authors: Malbois Fabienne
Published: March 2018

La transidentité de Chelsea (Bradley) Manning relève d’une production de genre dont l’analytique de la performance, à laquelle s’adossent les théories dramaturgiques de Judith Butler et Harold Garfinkel, ne peut rendre compte qu’en partie seulement. Le rapport particulier à la visibilité que cette figure publique entretient nécessite de développer une analytique de la reconnaissance ancrée dans la phénoménologie capacitaire de Paul Ricœur. L’examen de trois événements significatifs du parcours de vie de Chelsea (Bradley) Manning dans l’espace public anglo-saxon donne l’occasion d’observer différentes modalités de la reconnaissance et de discuter les présupposés qui grèvent les théories du genre de Butler et Garfinkel.
Penser politiquement la communication publique
Authors: Demers François , Rueff Julien
Published: March 2018

Le syntagme « communication publique » désigne un domaine d’études s’intéressant aux manifestations multiples et variables de la parole publique. Le présent article examine plusieurs présupposés partagés par les recherches en communication publique, dans l’idée d’évaluer leur adéquation avec l’intention de donner une intelligibilité politique à ces phénomènes communicationnels. À la lumière de la pensée politique d’Antonio Gramsci, les auteurs analysent dans quelle mesure ces présupposés permettent de penser la compénétration des modalités coercitive et discursive du pouvoir politique, les antagonismes irréductibles et indécidables entre les groupes sociaux, mais aussi les articulations entre la société civile et la société politique.

Recursive Spatial Multiplexing with Adaptive Interference Whitening
Authors: Mohamad Usama Y. , Shah Ibrahim A. , Hunziker Thomas , Dahlhaus Dirk H.
Published: March 2018

This article describes how recursive spatial multiplexing (RSM) is a closed-loop multiple-input multiple-output (MIMO) structure for achieving the capacity offered by MIMO channels with a low-complexity detector. The authors investigate how to make RSM able to provide a bit-error rate performance, which is robust against different types and levels of interference. The interference arising from simultaneous transmission of information signals is taken into account in the RSM scheme at the receiver using a whitening approach. Here, the covariance matrix is estimated and used subsequently for defining the retransmission subspace identifier to be fed back to the transmitter. The performance of this adaptive RSM scheme is compared with standard linear detection schemes like zero-forcing and minimum mean-squared error receivers. It turns out that the adaptive interference whitening substantially improves the bit-error rate performance. Moreover, adaptive RSM leads to a performance being independent of the correlation coefficient of the interference signals.

Published: March 2018

The distribution of residual pesticides in soil and rice grain was studied in rice farming area covered in Samchuk district, Suphanburi province, Thailand. The 19 samples of soil and rice grain were collected by random sampling in 2015 covered 7 sub-districts. The residual carbofuran and glyphosate in soil and rice grain was quantitative determined based on standard method. It was found that the concentration of carbofuran was found in the range of ND-0.0512 µg/kg and ND-0.0865 µg/kg for soil and rice grain, respectively. Glyphosate was found in the range of ND-0.2632 µg/kg and ND-0.2244 µg/kg for soil and rice grain, respectively. The residual levels of carbofuran and glyphosate in soil and rice grain depended on a spray period time, their decomposition and their concentration usage. The residual levels of carbofuran and glyphosate did not significantly quantitative correlation between soil and rice grain for this study area.

Authors: Chansuvarn Woravith
Published: March 2018

The aim of this work was to study the potential of the agricultural waste byproduct as a low-cost adsorbent for removal of phosphate ion (PO43-) from synthetic wastewater. The simple preparation of carbonized filter cake (CFC) was performed at 550°C. CFC was also characterized using FTIR, X-ray fluorescence analysis. The adsorptive parameters of batch experiment, such as pH of solution, dosage and contact time were systematically studied in order to the optimization condition. The optimum conditions of pH, contact time and adsorbent dose were to be 6, 60 min, and 2 g/L, respectively. The Langmuir and Freundlich isotherms were used to calculate the adsorption parameters that was able to describe the equilibrium isotherm and adsorptive mechanism. The maximum monolayer adsorption capacity of CFC was estimated as 20.32 mg/g. The optimized condition was applied for phosphate removal from synthetic wastewater. The achieved phosphate removal efficiency from synthetic wastewater sample was to be 92.4%. Filter cake is a low-cost byproduct of sugar cane but it can also highly effective remove phosphate ion from aqueous solution. The modification of filter cake surface via chemical reaction as a new adsorbent in order to increase surface sites and high affinity with phosphate ion will also be further studied.
