Published: January 2017

A critical component of exoplanetary studies is an exhaustive characterization of the host star, from which the planetary properties are frequently derived. Of particular value are the radius, temperature, and luminosity, which are key stellar parameters for studies of transit and habitability science. Here we present the results of new observations of Wolf 1061, known to host three super-Earths. Our observations from the Center for High Angular Resolution Astronomy interferometric array provide a direct stellar radius measurement of 0.3207 ± 0.0088 R
⊙, from which we calculate the effective temperature and luminosity using spectral energy distribution models. We obtained 7 yr of precise, automated photometry that reveals the correct stellar rotation period of 89.3 ± 1.8 days, finds no evidence of photometric transits, and confirms that the radial velocity signals are not due to stellar activity. Finally, our stellar properties are used to calculate the extent of the Habitable Zone (HZ) for the Wolf 1061 system, for which the optimistic boundaries are 0.09–0.23 au. Our simulations of the planetary orbital dynamics show that the eccentricity of the HZ planet oscillates to values as high as ∼0.15 as it exchanges angular momentum with the other planets in the system.
A GALACTIC MOLECULAR CLOUD CLUMP CATALOG FROM HI-GAL DATA: METHOD AND INITIAL RESULTS COMPARISON WITH BGPS
Authors: Zetterlund Erika , Glenn Jason , Rosolowsky Erik
Published: January 2017

As the precursors to stellar clusters, it is imperative that we understand the distribution and physical properties of dense molecular gas clouds and clumps. Such a study has been done with the ground-based Bolocam Galactic Plane Survey (BGPS). Now the Herschel infrared GALactic plane survey (Hi-GAL) allows us to do the same with higher-quality data and complete coverage of the Galactic plane. We have made a pilot study comparing dense molecular gas clumps identified in Hi-GAL and BGPS, using six 2° × 2° regions centered at Galactic longitudes of

, 30°, 41°, 50°, 202°, and 217°. We adopted the BGPS methodology for identifying clumps and estimating distances, leading to 6198 clumps being identified in our substudy, with 995 of those having well-constrained distances. These objects were evenly distributed with Galactic longitude, a consequence of Hi-GAL being source confusion limited. These clumps range in mass from 10−2 to 105
M
⊙ and have heliocentric distances of up to 16 kpc. When clumps found in both surveys are compared, we see that distances agree within 1 kpc and ratios of masses are of the order of unity. This serves as an external validation for BGPS and instills confidence as we move forward to cataloging the clumps from the entirety of Hi-GAL. In addition to the sources that were in common with BGPS, Hi-GAL found many additional sources, primarily due to the lack of atmospheric noise. We expect Hi-GAL to yield 2 × 105 clumps, with 20% having well-constrained distances, an order of magnitude above what was found in BGPS.

We have obtained new images of the protoplanetary disk orbiting TW Hya in visible, total intensity light with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope (HST), using the newly commissioned BAR5 occulter. These HST/STIS observations achieved an inner working angle of ∼0.″2, or 11.7 au, probing the system at angular radii coincident with recent images of the disk obtained by ALMA and in polarized intensity near-infrared light. By comparing our new STIS images to those taken with STIS in 2000 and with NICMOS in 1998, 2004, and 2005, we demonstrate that TW Hya’s azimuthal surface brightness asymmetry moves coherently in position angle. Between 50 au and 141 au we measure a constant angular velocity in the azimuthal brightness asymmetry of 22.°7 yr−1 in a counterclockwise direction, equivalent to a period of 15.9 yr assuming circular motion. Both the (short) inferred period and lack of radial dependence of the moving shadow pattern are inconsistent with Keplerian rotation at these disk radii. We hypothesize that the asymmetry arises from the fact that the disk interior to 1 au is inclined and precessing owing to a planetary companion, thus partially shadowing the outer disk. Further monitoring of this and other shadows on protoplanetary disks potentially opens a new avenue for indirectly observing the sites of planet formation.

We present new Atacama Large Millimeter/submillimeter Array Band 7 (∼340 GHz) observations of the dense gas tracers HCN, HCO+, and CS in the local, single-nucleus, ultraluminous infrared galaxy IRAS 13120–5453. We find centrally enhanced HCN (4–3) emission, relative to HCO+ (4–3), but do not find evidence for radiative pumping of HCN. Considering the size of the starburst (0.5 kpc) and the estimated supernovae rate of ∼1.2 yr−1, the high HCN/HCO+ ratio can be explained by an enhanced HCN abundance as a result of mechanical heating by the supernovae, though the active galactic nucleus and winds may also contribute additional mechanical heating. The starburst size implies a high ΣIR of 4.7 × 1012
L
⊙ kpc−2, slightly below predictions of radiation-pressure limited starbursts. The HCN line profile has low-level wings, which we tentatively interpret as evidence for outflowing dense molecular gas. However, the dense molecular outflow seen in the HCN line wings is unlikely to escape the Galaxy and is destined to return to the nucleus and fuel future star formation. We also present modeling of Herschel observations of the H2O lines and find a nuclear dust temperature of ∼40 K. IRAS 13120–5453 has a lower dust temperature and ΣIR than is inferred for the systems termed “compact obscured nuclei (CONs)” (such as Arp 220 and Mrk 231). If IRAS 13120–5453 has undergone a CON phase, we are likely witnessing it at a time when the feedback has already inflated the nuclear ISM and diluted star formation in the starburst/active galactic nucleus core.
Inflow, Outflow, Yields, and Stellar Population Mixing in Chemical Evolution Models
Authors: Andrews Brett H. , Weinberg David H. , Schönrich Ralph , Johnson Jennifer A.
Published: January 2017

Chemical evolution models are powerful tools for interpreting stellar abundance surveys and understanding galaxy evolution. However, their predictions depend heavily on the treatment of inflow, outflow, star formation efficiency (SFE), the stellar initial mass function, the SN Ia delay time distribution, stellar yields, and stellar population mixing. Using flexCE, a flexible one-zone chemical evolution code, we investigate the effects of and trade-offs between parameters. Two critical parameters are SFE and the outflow mass-loading parameter, which shift the knee in [O/Fe]–[Fe/H] and the equilibrium abundances that the simulations asymptotically approach, respectively. One-zone models with simple star formation histories follow narrow tracks in [O/Fe]–[Fe/H] unlike the observed bimodality (separate high-α and low-α sequences) in this plane. A mix of one-zone models with inflow timescale and outflow mass-loading parameter variations, motivated by the inside-out galaxy formation scenario with radial mixing, reproduces the two sequences better than a one-zone model with two infall epochs. We present [X/Fe]–[Fe/H] tracks for 20 elements assuming three different supernova yield models and find some significant discrepancies with solar neighborhood observations, especially for elements with strongly metallicity-dependent yields. We apply principal component abundance analysis to the simulations and existing data to reveal the main correlations among abundances and quantify their contributions to variation in abundance space. For the stellar population mixing scenario, the abundances of α-elements and elements with metallicity-dependent yields dominate the first and second principal components, respectively, and collectively explain 99% of the variance in the model. flexCE is a python package available at https://github.com/bretthandrews/flexCE.
Laboratory Investigations into the Spectra and Origin of Propylene Oxide: A Chiral Interstellar Molecule
Authors: Hudson R. L. , Loeffler M. J. , Yocum K. M.
Published: January 2017

Propylene oxide was recently identified in the interstellar medium, but few laboratory results are available for this molecule to guide current and future investigations. To address this situation, here we report infrared spectra, absorption coefficients, and band strengths of solid propylene oxide along with the first measurement of its refractive index and a calculation of its density, all for the amorphous solid form of the compound. We present the first experimental results showing a low-temperature formation pathway for propylene oxide near 10 K in interstellar ice analogs. Connections are drawn between our new results and the interstellar molecules propanal and acetone, and predictions are made about several as yet unobserved vinyl alcohols and methylketene. Comparisons are given to earlier laboratory work and a few applications to interstellar and solar system astrochemistry are described.
A Surface Density Perturbation in the TW Hydrae Disk at 95 au Traced by Molecular Emission

Published: January 2017

We present ALMA Cycle 2 observations at 0.″5 resolution of TW Hya of CS

emission. The radial profile of the integrated line emission displays oscillatory features outward of 1.″5 (

au). A dip-like feature at 1.″6 is coincident in location, depth, and width with features observed in dust scattered light at near-infrared wavelengths. Using a thermochemical model indicative of TW Hya, gas-grain chemical modeling, and non-LTE radiative transfer, we demonstrate that such a feature can be reproduced with a surface density depression, consistent with the modeling performed for scattered-light observations of TW Hya. We further demonstrate that a gap in the dust distribution and dust opacity only cannot reproduce the observed CS feature. The outer enhancement at 3.″1 is identified as a region of intensified desorption due to enhanced penetration of the interstellar far-UV radiation at the exponential edge of the disk surface density, which intensifies the photochemical processing of gas and ices.

The deuterium enrichment of molecules is sensitive to their formation environment. Constraining patterns of deuterium chemistry in protoplanetary disks is therefore useful for probing how material is inherited or reprocessed throughout the stages of star and planet formation. We present ALMA observations at ∼0.″6 resolution of DCO+, H13CO+, DCN, and H13CN in the full disks around T Tauri stars AS 209 and IM Lup, in the transition disks around T Tauri stars V4046 Sgr and LkCa 15, and in the full disks around Herbig Ae stars MWC 480 and HD 163296. We also present ALMA observations of HCN in the IM Lup disk. DCN, DCO+, and H13CO+ are detected in all disks, and H13CN in all but the IM Lup disk. We find efficient deuterium fractionation for the sample, with estimates of disk-averaged DCO+/HCO+ and DCN/HCN abundance ratios ranging from ∼0.02–0.06 and ∼0.005–0.08, respectively, which is comparable to values reported for other interstellar environments. The relative distributions of DCN and DCO+ vary between disks, suggesting that multiple formation pathways may be needed to explain the diverse emission morphologies. In addition, gaps and rings observed in both H13CO+ and DCO+ emission provide new evidence that DCO+ bears a complex relationship with the location of the midplane CO snowline.

Published: January 2017

We present a new computational method for calculating the motion of stars in a dwarf spheroidal galaxy (dSph) that can use either Newtonian gravity or Modified Newtonian Dynamics (MOND). In our model, we explicitly calculate the motion of several thousand stars in a spherically symmetric gravitational potential, and we  statistically obtain both the line-of-sight bulk velocity dispersion and dispersion profile. Our results for MOND calculated bulk dispersions for Local Group dSph’s agree well with previous calculations and observations. Our MOND calculated dispersion profiles are compared with the observations of Walker et al. for Milky Way dSph’s, and we present calculated dispersion profiles for a selection of Andromeda dSph’s.

We report the first detailed chemical abundance analysis of the exoplanet-hosting M-dwarf stars Kepler-138 and Kepler-186 from the analysis of high-resolution (R ∼ 22,500) H-band spectra from the SDSS-IV–APOGEE survey. Chemical abundances of 13 elements—C, O, Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, and Fe—are extracted from the APOGEE spectra of these early M-dwarfs via spectrum syntheses computed with an improved line list that takes into account H2O and FeH lines. This paper demonstrates that APOGEE spectra can be analyzed to determine detailed chemical compositions of M-dwarfs. Both exoplanet-hosting M-dwarfs display modest sub-solar metallicities: [Fe/H]Kepler-138 = −0.09 ± 0.09 dex and [Fe/H]Kepler-186 = −0.08 ± 0.10 dex. The measured metallicities resulting from this high-resolution analysis are found to be higher by ∼0.1–0.2 dex than previous estimates from lower-resolution spectra. The C/O ratios obtained for the two planet-hosting stars are near-solar, with values of 0.55 ± 0.10 for Kepler-138 and 0.52 ± 0.12 for Kepler-186. Kepler-186 exhibits a marginally enhanced [Si/Fe] ratio.
Pionnière et discutée : la réforme agraire au Mexique depuis 1917
Authors: Tortolero Villaseñor Alejandro , Touboul Tardieu Eva
Published: January 2017

Cet article interroge d’abord les principales sources d’inspiration de la réforme agraire mexicaine, inscrite à la fois dans le contexte de la révolution entamée en 1910 et dans la recherche d’un fondement à la nation en construction. Le diagnostic d’A. Molina Enríquez, selon lequel l’hacienda (grande propriété et exploitation extensive de la terre) est la cause du retard agricole du pays, devient le schéma d’interprétation dominant. À l’instar des « régénérateurs » espagnols de la fin du XIX e siècle, Molina met en relief la communauté mais insiste aussi sur le rôle, y compris politique, de la petite propriété du ranchero (le petit paysan) appelé à devenir le principal fondement de la nation métisse mexicaine. C’est ce modèle qu’adoptent les révolutionnaires, en simplifiant outrancièrement la mosaïque agraire mexicaine. Ainsi la constitution de 1917 précise que les terres et les eaux sont le patrimoine de la nation et prévoit leur distribution en dotant les communautés de biens (les ejidos ) en principe prélevés sur les haciendas. Il s’agit de biens possédés en communs mais exploités individuellement. En fait, la mise en œuvre de cette réforme agraire a connu des modalités et des rythmes différents, allant du maintien des haciendas (parfois récupérées par les généraux révolutionnaires) à la reconstitution des pueblos (villages) traditionnels avec leurs ejidos . Elle s’est parfois accélérée, comme sous le gouvernement de L. Cardenas, en 1934. Entre 1920 et 1964, elle a distribué 53 millions ha (27 % de la superficie agraire du pays). En définitive, cette transformation, tout en consolidant l’ejido , a assuré la primauté du petit exploitant bien que sous le contrôle de l’État.
Integrative Review of Admission Factors Related to Associate Degree Nursing Program Success
Authors: Olsen Jeanette M.
Published: January 2017

Background:

High attrition in associate degree nursing (ADN) programs contributes to the nursing shortage and causes hardship for students, families, faculty, colleges, and taxpayers. The purpose of this integrative literature review is to identify admission criteria related to ADN program success to inform evidence-based admission policies and reduce attrition.

Method:

Integrative review methodology, suggested by Whittemore and Knafl, was used. A systematic search of existing professional literature was conducted using five databases and key word searches. The final sample included 26 documents that were analyzed and synthesized with the matrix method.

Results:

Five categories of admission criteria and factors related to success in ADN programs were revealed from the analysis of findings: academic aptitude, demographic factors, psychological hardiness, specialty skills and experience, and socioeconomic support.

Conclusion:

ADN programs with a goal of decreasing attrition may want to implement admission selection guidelines that consider applicant criteria and attributes across all five dimensions. [

Healthy Lifestyle Behaviors and Health Promotion Attitudes in Preregistered Nurses: A Questionnaire Study
Authors: Blake Holly , Stanulewicz Natalia , Griffiths Katherine
Published: January 2017

Background:

Nurses report inadequacies in health promotion practices. This study investigated attitudes toward being role models for healthy eating, and examined predictors of health promotion attitudes in preregistered nurses.

Method:

A questionnaire was completed by 493 preregistered nurses. Measures included health promotion attitudes, healthy lifestyle index, self-esteem, and body satisfaction.

Results:

Preregistered nurses (89.5%) felt that nurses should be role models for health. However, 37% had a negative health promotion attitude and were more likely to be dissatisfied with their body and lead less healthy lifestyles. Most preregistered nurses (96%) felt that delivering health promotion would be a key element of their job and held positive health promotion attitudes. Healthy lifestyle was the most consistent significant predictor of health promotion attitude.

Conclusion:

Preregistered nurses with an unhealthy lifestyle and lower self-esteem held a more negative health promotion attitude. Intervention is needed to support preregistered nurses in making healthy lifestyle choices, improving their self-perception and health promotion attitude. [

Recent Framework of TVET Teacher Education in a Country on the Path to Reform
Authors: Bünning Frank , Schmidt Ulrike
Published: January 2017

This chapter discussed TVET teacher education in Myanmar on the threshold of the 21st century; a qualitative analysis of the present state of the art. Recent status of Myanmar's TVET system was highlighted and the chapter strongly maintained that qualified and motivated teachers and instructors are key for effective learning and are as well at the heart of TVET quality. The chapter provided a comprehensive problem scenario with regard to TVET teacher training; to mention a few, that there is a low awareness for the relevance of TVET in general and with respect to its potential to develop a country's skilled and semi-skilled workers. In comparison to university degrees, graduating from training courses at vocational institutions is not perceived as a valuable career option. Lastly, this chapter attempts to add to the collection of vocational education and training research by consulting a case in Myanmar – a country which currently possesses only a sparse amount of data in this field.
Redesign of Home Care Service Delivery
Authors: Mäkimattila Martti , Melkas Helinä , Uotila Tuomo
Published: January 2017

This paper delineates how systemic innovations coevolve with organisations in the context of home care and describes the dynamics in shared innovation activities when information technology (IT) systems are developed for such services. Innovation literature is presented from the system perspective to highlight non-technological characteristics. The case study of home-care services in Finland in 2010–2014 shows that systemic innovations result from collaborative actions because the complexity of these innovations requires knowledge and skills from different fields, which no single entity possesses. The multi-level dynamics challenges the management alternatives that focus either on larger development platforms for transitions, or product-based diffusion – then facing later obstacles related to fragmented solutions when merging IT systems and processes. This study contributes by exploring the complexity of developing innovative solutions under dynamic conditions, when actors have different focuses, interests and interdependencies.
Semantic Reconciliation of Electronic Health Records Using Semantic Web Technologies
Authors: El Guemhioui Karim , Demurjian Steven A.
Published: January 2017

In this paper, the authors present an approach to reconcile the semantics of distinct medical terms found in personal health records (PHRs - that store data controlled by patients) and electronic medical records (EMRs - that store data controlled by providers) that are utilized to describe the same concept in different systems. The authors present a solution for semantic reconciliation based on RDF and related semantic web technologies. As part of the solution, the authors utilize a centralized repository of ontologies to: uniformly interrogate the medical coding systems in which those terms are defined, extract all of their published synonyms, and save the results as RDF triples. The final step in the process is to employ a reasoner to infer non-explicit synonymy among those terms, hence evidencing the underlying semantics to the PHR and EMR systems for possible further processing.
Effects of the Window Size and Feature Extraction Approach for Arrhythmia Classification
Authors: Alfarhan Khudhur A. , Mashor Mohd Yusoff , Mohd Saad Abdul Rahman , Azeez Hayder A. , Sabry Mustafa M.
Published: January 2017

Arrhythmia, a common form of heart disease, can be detected from an electrocardiogram (ECG) signal. This research work presents a comparative study between five feature extraction methods applied separately on two window sizes for detecting three ECG pulse types, namely normal and two arrhythmia variations. The library support vector machine (LIBSVM) was used to classify the three classes of the ECG pulses. The ECG signals were obtained from MIT-BIH database. The ECG dataset was normalized and filtered to remove any noise and after that the signals were windowed into two window sizes (long window and short window). Five approaches were used to extract the features from the ECG signals. These approaches are scalar Autoregressive model coefficients, Haar discrete wavelet transform (DWT), Daubechies (db) DWT, Biorthogonal (bior) DWT, and principal components analysis (PCA). Each approach was applied separately on the two window sizes. The results of the classification show that scalar Autoregressive model coefficients, Haar, db, and bior are better approaches to catch the ECG features for short window than the long window. However, PCA gave the closest and highest results for the two window sizes than other approaches. That mean the PCA is the better feature extraction approach for both window sizes.
Dynamic Balance Analysis under Different Lower Extremities Tortuosity
Authors: Qian Dan Dan , Li Yun Tao , Shu Yang , Gu Yao Dong , Zhang Yan , Awrejcewicz Jan , Jia Xue Wen
Published: January 2017

The purpose of this study was to explore the balance of different condition of grounds through changing the inclines, and investigate the influence of lower extremities in different inclines. 20 healthy young males were taken as experimental participants. The Six-degree-of-freedom Motion Platform was taken to change the inclines to: -5°,0°,5°,10°. The Vicon three-dimension motion analysis system was utilized to capture the spatiotemporal parameters and the three-dimensional coordinates of lower extremities. On uphill, incline had no significant impact on balance. But tortuosity of hip and knee could significantly increase with the incline. On downhill, balance was significantly less than flat. Tortuosity of knee joint was significant larger than it on the flat ground. The mobility of hip and knee joint was large on uphill; the mobility of knee is large on downhill, but the balance was reduced. These could provide useful biomechanics information on clinical evaluation with dynamic balance. The result might have great significance to the lower extremities rehabilitation.
Identification of Motile Sperm Domain–Containing Protein 2 as Regulator of Human Monocyte Migration
Authors: Mendel Itzhak , Yacov Niva , Salem Yaniv , Propheta-Meiran Oshrat , Ishai Eti , Breitbart Eyal
Published: January 2017

Binding of chemokines to their cognate receptors on monocytes instigates a cascade of events that directs these cells to migrate to sites of inflammation and cancerous tissues. Although targeting of selected chemokine receptors on monocytes exhibited preclinical efficacy, attempts to translate these studies to the clinic have failed thus far, possibly due to redundancy of the target receptor. We reveal that motile sperm domain–containing protein 2 (MOSPD2), a protein with a previously unknown function, regulates monocyte migration in vitro. This protein was found to be expressed on the cytoplasmic membrane of human monocytes. Silencing or neutralizing MOSPD2 in monocytes restricted their migration when induced by different chemokines. Mechanistically, silencing MOSPD2 inhibited signaling events following chemokine receptor ligation. When tested for expression in other immune cell subsets, MOSPD2 was apparent also, though less abundantly, in neutrophils, but not in lymphocytes. Thus, in the presence of neutralizing Abs, neutrophil migration was inhibited to some extent whereas lymphocyte migration remained intact. In view of these results, we suggest MOSPD2 as a potential target protein for treating diseases in which monocyte and neutrophil accumulation is correlated with pathogenesis.

Published: January 2017

We describe 70 cases of monocled cobra (Naja kaouthia) bite admitted to Chittagong Medical College Hospital, Bangladesh. The biting snakes were identified by examining the dead snake and/or detecting N. kaouthia venom antigens in patients' serum. Bites were most common in the early morning and evening during the monsoon (May–July). Ligatures were routinely applied to the bitten limb before admission. Thirty-seven patients consulted traditional healers, most of whom made incisions around the bite site. Fifty-eight patients experienced severe neurotoxicity and most suffered swelling and pain of the bitten limb. The use of an Indian polyvalent antivenom in patients exhibiting severe neurotoxicity resulted in clinical improvement but most patients experienced moderate-to-severe adverse reactions. Antivenom did not influence local blistering and necrosis appearing in 19 patients; 12 required debridement. Edrophonium significantly improved the ability of patients to open the eyes, endurance of upward gaze, and peak expiratory flow rate suggesting that a longer-acting anticholinesterase drug (neostigmine) could be recommended for first aid. The study suggested that regionally appropriate antivenom should be raised against the venoms of the major envenoming species of Bangladesh and highlighted the need to improve the training of staff of local medical centers and to invest in the basic health infrastructure in rural communities.
The Distance of Heaven: An Analysis of the Guodian Wu Xing
Authors: HAMM Matthew James
Published: January 2017

This paper argues that the Guodian Wu Xing consists of two interrelated sections that reflect its distinction between goodness (a characteristic of humans) and virtue (a trait of Heaven). Individually, each section emphasizes different aspects of self-cultivation. When read against one another, they articulate the text’s main argument that Heaven is a distant figure and that the sage, a figure who understands the Way of Heaven, is almost unreachable. As such, the text focuses on the gentleman, a figure who achieves virtue (defined as timeliness) within a dispositional context by emulating Heaven in accordance with the Way of the Gentleman.

Previous studies have examined the efficacy of the verbal and visual representation of words while reading L2 texts, concluding that it facilitates incidental word retention. This study explores other potentials of multimodal L2 vocabulary learning: explicit learning with a multimodal dictionary could enhance not only word retention, but also text comprehension; the dictionary could serve not only as a reference tool, but also as a learning tool; and technology-enhanced visual glosses could facilitate deeper text comprehension. To verify these claims, this study investigates the multimodal representations’ effects on Japanese students learning L2 locative prepositions by developing two online dictionaries, one with static pictures and one with animations. The findings show the advantage of such dictionaries in explicit learning; however, no significant differences are found between the two types of visual glosses, either in the vocabulary or in the listening tests. This study confirms the effectiveness of multimodal L2 materials, but also emphasizes the need for further research into making the technologically enhanced materials more effective.

Psychometric Properties of the Parents as Partners in Intervention (PAPI) Questionnaires
Authors: Waldman-Levi Amiya , Hirsch Idit , Gutwillig Galia , Parush Shula
Published: January 2017

This article describes two studies that focused on parents’ expectations and satisfaction with occupational therapy intervention for their children (N = 208). The first study determined the psychometric properties of the Parents as Partners in Intervention (PAPI) Questionnaire set (n = 146). The 2nd study examined parental expectations, satisfaction, and perception of their child’s functional gains from individual- (n = 30 parents) and group- (n = 32 parents) based interventions. Overall, the results of these studies further support the PAPI Questionnaire set's validity and reliability and suggest that parents’ expectations are high and not necessarily in line with their actual satisfaction with the outcomes of their child’s intervention and functional gains.
Ultramafic rocks in the North Patagonian Andes: is their emplacement associated with the Neogene tectonics of the Liquiñe–Ofqui Fault Zone?

Serpentinites and fresh or partially serpentinized harzburgite crop out in the western slope of the North Patagonian Andes of continental Chiloé (41°44’-42°12’S). These rocks are spatially associated with low-grade metamorphic rocks containing Cenozoic detrital zircons. The metamorphic rocks, together with Devonian metasediments, have been mapped previously as Late Paleozoic-Triassic metamorfic complex, an age no longer tenable for at least part of the complex. Transpressional tectonic emplacement of the ultramafic body or bodies is thought to have been related to activity on the Liquiñe-Ofqui Fault Zone, following a late Oligocene-Early Miocene extensional phase in the forearc region of the present Andes. This fault zone occurs immediately east of the outcrops of the ultramafic rocks and has been interpreted previously as generating a hemi-flower or flower structure.
Transexualidade e o “direito dos banheiros” no STF: uma reflexão à luz de Post, Siegel e Fraser
Authors: Bunchaft Maria Eugenia
Published: January 2017

Este trabalho objetiva investigar o voto do Ministro Luís Roberto Barroso no julgamento do Recurso Extraordinário n. 845779 à luz dos referenciais teóricos de Post, Siegel, Honneth e Fraser. Pretende-se demonstrar que o argumento utilizado pelo Ministro Luís Roberto Barroso, relativo ao papel contramajoritário do STF na proteção de grupos vulneráveis, se aproxima dos pressupostos do Constitucionalismo Democrático defendido por Post e Siegel. Sustenta-se que, a despeito da preocupação do eminente Ministro-Relator com a efetivação dos direitos de transexuais e do conteúdo progressista de seu voto, sua argumentatividade não revela alcance teórico para desestabilizar a estrutura binária inerente às práticas normalizadoras que estabelecem padrões heteronormativos, posto que pressupõe, implicitamente, o paradigma da autorrealização delineado por Honneth. O trabalho é original, pois propugna-se que, somente, uma nova teoria - um Constitucionalismo Democrático-Paritário - pode desmascarar assimetrias de poder decorrentes da própria esfera pública oficial e que se refletem em decisões judiciais vinculadas a concepções heteronormativas. Utilizam-se a análise discursiva crítica feminista e os métodos de indução analítica e monográfico. A técnica de pesquisa é a documentação indireta.
A cláusula de interdição de concorrência no direito brasileiro e sua fundamentação histórica: o caso da Companhia dos Tecidos de Juta (1914). Notas sobre seus reflexos normativos, doutrinários e jurisprudenciais

O tema da concorrência desleal conta presentemente com uma regra no Código Civil Brasileiro de 2002. O artigo explora seus fundamentos históricos. Com esse objetivo, o artigo analisa um caso da década de 1910, no qual dois grandes advogados e um ministro da Suprema Corte tiveram um papel especial. Esses bacharéis fixaram o conceito de concorrência desleal, no contexto compreensivo de aviamento e de clientela. O artigo também apresenta alguma referência bibliográfica relativa ao caso, bem como a construção jurisprudencial em torno da questão, inclusive em outros campos do direito, a exemplo do direito do trabalho.
The impact of resolution on meteorological, chemical and aerosol properties in regional simulations with WRF-Chem

Published: January 2017

Abstract. Limited area (regional) models applied at high resolution over specific regions of interest are generally expected to more accurately capture the spatiotemporal variability of key meteorological and climate parameters. However, improved performance is not inevitable, and there remains a need to optimize use of numerical resources and to quantify the impact on simulation fidelity that derives from increased resolution. The application of regional models for climate forcing assessment is currently limited by the lack of studies quantifying the sensitivity to horizontal spatial resolution and the physical–dynamical–chemical schemes driving the simulations. Here we investigate model skill in simulating meteorological, chemical and aerosol properties as a function of spatial resolution, by applying the Weather Research and Forecasting model with coupled Chemistry (WRF-Chem) over eastern North America at different resolutions. Using Brier skill scores and other statistical metrics it is shown that enhanced resolution (from 60 to 12 km) improves model performance for all of the meteorological parameters and gas-phase concentrations considered, in addition to both mean and extreme aerosol optical depth (AOD) in three wavelengths in the visible relative to satellite observations, principally via increase of potential skill. Some of the enhanced model performance for AOD appears to be attributable to improved simulation of meteorological conditions and the concentration of key aerosol precursor gases (e.g., SO2 and NH3). Among other reasons, a dry bias in the specific humidity in the boundary layer and a substantial underestimation of total monthly precipitation in the 60 km simulations are identified as causes for the better performance of WRF-Chem simulations at 12 km.
The lower actinopterygian fauna from the Lower Carboniferous Albert shale formation of New Brunswick, Canada – a review of previously described taxa and a description of a new genus and species
Authors: Mickle Kathryn E.
Published: January 2017

Abstract. The Lower Carboniferous Albert shale formation of New Brunswick, Canada, is well-known for the preservation of countless articulated lower actinopterygian palaeoniscoid fishes. This site is at the boundary between the Devonian and the Lower Carboniferous, making the lower actinopterygians preserved at this site important. The taxonomic history of previously described Albert shale formation actinopterygians is reviewed here. Many of the earliest described actinopterygian taxa from the Albert Formation are represented by poorly preserved type specimens and have the distinction of being moved from one paraphyletic genus to another paraphyletic genus. While these taxa are in need of major redescriptions, such work is premature until the large paraphyletic or polyphyletic genera they have been placed in, Palaeonicus[m], †Rhadinichthys, and †Elonichthys, are redescribed. But there is new diversity within the Albert shale formation. Here, a new lower actinopterygian species, †Lambeia pectinatus, is described from one well-preserved specimen. This new species is characterized by dorsal ridge scales with pectinated posterior margins, body scales inserted between adjacent dorsal ridge scales, body scales with pectinated posterior and ventral margins, the presence of a ventral rostro-premaxilla and a median rostral bone, a separate and distinct antorbital bone, and a single supraorbital bone. This newly described species is distinct from previously described fishes from the Albert Formation, and the morphology of this newly described species is more similar to later Carboniferous fishes rather than Devonian fishes. This suggests that morphological features commonly seen in Carboniferous fishes and rarely seen in Devonian fishes were present early in the Carboniferous.

QUANTIFICATION OF THE CONTRIBUTION OF FILLER CHARACTERISTICS TO NATURAL RUBBER REINFORCEMENT USING PRINCIPAL COMPONENT ANALYSIS
Authors: Barrera Cindy S. , Soboyejo Alfred B. O. , Cornish Katrina
Published: January 2017

Practical statistical models were developed to quantify individual contributions from characteristics of conventional and non-conventional fillers and predict resulting mechanical properties of both hevea and guayule natural rubber composites. Carbon black N330 and four different agro-industrial residues, namely, eggshells, carbon fly ash, processing tomato peels, and guayule bagasse, were used in this study. Filler characteristics were used as explanatory variables in multiple linear regression analyses. Principal component analysis was used to evaluate correlations among explanatory variables based on their correlation matrices and to transform them into a new set of independent variables, which were then used to generate reliable regression models. Surface area, dispersive component of surface energy, carbon black, and waste-derived filler loading were found to have almost equal importance in the prediction of composite properties. However, models developed for ultimate elongation poorly explained variability, indicating the dependence of this property on other variables. Agro-industrial residues could potentially serve as more sustainable fillers for polymer composites than conventional fillers. This new modeling approach for polymer composites allows the performance of a wide range of different waste-derived fillers to be predicted with minimum laboratory work, facilitating the optimization of compound recipes to address specific product requirements.

Latinoamérica se caracteriza por enfrentar problemas de desarrollo, por ello se implementan políticas que favorezcan a las personas y que estas se apropien de beneficios, el fin de estas políticas es sacar a la ciudadanía de la pobreza, brindándoles herramientas para mejorar sus niveles de vida, esto es posible gracias a la sostenibilidad humanista que permita el uso de recursos de una manera justa y equitativa, equipando de instrumentos que sirvan para mejorar conocimientos como nación, para esto es necesario una participación ciudadana abierta que genere debates y surjan ideas positivas para los gobernantes, hay fenómenos naturales y humanos que no permiten el avance de las naciones, el factor desempleo ocasiona mucha inseguridad por esto surgen grupos delincuenciales que afectan la paz y la tranquilidad de los pueblos, son pocas las naciones que promueven una convivencia y seguridad de forma integral donde la población es la principal protagonista, ejemplo es Nicaragua, garante y referente de la región por niveles altos de seguridad, esto es posible gracias a un modelo que contribuye y aboga por inclusión, educación gratuita y de calidad. Nicaragua es un muro de contención en la región frenando grupos delincuenciales y de narcotráfico que afectan a nuestra juventud nicaragüense.
