Authors: Peretti Marizete , Todero Itacir
Published: September 2018

O presente trabalho tem o viés de apresentar algumas nuances sobre a notoriedade que vem ganhando a judicialização da política e o ativismo judicial no Brasil, mais especificamente no que se refere ao direito previdenciário. Aborda-se também a importância da observação do princípio do não retrocesso das conquistas sociais como forma de garantia da segurança e da ordem social, preceitos constitucionais que visam a manutenção da justiça social como um todo. No presente artigo utiliza-se o método dedutivo com a técnica da revisão bibliográfica.
Responsabilidade Fiscal: uma obra inacabada
Authors: Afonso José Roberto R. , Nóbrega Marcos
Published: September 2018

Uma das reformas mais profundas estabelecidas no ambiente institucional brasileiro na última década foi, sem nenhuma margem de dúvida, a responsabilidade fiscal com princípio vetor da administração pública que foi densificado com a edição da Lei de Responsabilidade Fiscal (LC nº 101/00). Apesar dos enormes avanços, a LRF não pode ser vista como obra acabada. Importantes instituições e regras contempladas na lei até hoje não foram criadas ou regulamentadas, nem entraram em vigor. Em alguns casos, as normas até têm efeito legal, mas não prático. Esta análise procura levantar muitas questões, algumas confessadamente como provocações, a fim de tentar motivar mais e melhores discussões, para que se de continuidade às mudanças nas estruturas fiscais do país. Assim, vários tópicos da LRF que carecem de regulamentação são discutidos com ênfase na melhor adequação ou mesmo sua revisão.
A revelia e seus efeitos no âmbito dos Tribunais de Contas
Authors: Alexandre Gleydson Antônio Pinheiro
Published: September 2018

O presente trabalho tem por objetivo examinar o instituto da revelia e seus efeitos, especialmente a confissão ficta, no tocante aos processos perante os Tribunais de Contas. Demonstrar-se-á a legislação pertinente (Leis Orgânicas e Regimentos Internos das Cortes de Contas pátrias) que autoriza a utilização da revelia, contudo, ao final, com base em doutrina especializada, mostrar-se-á a impossibilidade do emprego de todos os efeitos processualísticos da revelia, uma vez os princípios do processo administrativo.

Custeio dos serviços prestados por empresas concessionárias: tarifa, preço público ou taxa
Authors: Câmara Delano Carneiro da Cunha
Published: September 2018

Trata da tarifa cobrada pelas concessionárias de serviços públicos que se distingue da taxa (tributo) e do preço público (receita originária do Estado). A doutrina tende a equiparar o preço público à tarifa a partir de bases conceituais tributárias. A distinção é identificada pelo direito financeiro, regulatório, dentre outros ramos jurídicos.
A eficácia dos direitos fundamentais de 2ª dimensão e o orçamento público impositivo
Authors: Gradvohl Michel André Bezerra Lima
Published: September 2018

Compreender a eficácia das normas constitucionais que consagram os direitos fundamentais de segunda dimensão é fundamental para se desenvolver qualquer projeto que vise a concretização destes. Na doutrina, encontra-se grave divergência quanto à condição de se poder demandar direitos subjetivos a partir da própria norma constitucional definidora dos direitos sociais, mas quanto à eficácia objetiva destas o consenso impera a favor da sua existência. Um dos efeitos dessa eficácia objetiva, como se busca informar nesse artigo, deve ser a imposição ao Poder Executivo, ao menos em certas circunstâncias, de realizar os programas específicos previstos na Lei Orçamentária e que concretizam direitos fundamentais de 2ª dimensão.
A utilização da ADPF como meio de declaração de inconstitucionalidade de ato normativo municipal ante a Constituição Federal

Published: September 2018

Apresenta-se uma síntese sobre a origem dos Municípios, e a problemática referente à competência para decidir sobre o controle da constitucionalidade de lei municipal, caso haja divergência frente às determinações da Constituição do Estado ou da Constituição Federal, e ainda, à possibilidade jurídica da solução dada pelo legislador, através da utilização da Argüição de Descumprimento de Preceito Fundamental- ADPF, como solução para a falta de previsão constitucional de controle concentrado de lei municipal pelo STF, em virtude da elaboração do texto do artigo 102, I, “a” da Carta Magna.
Aspectos Jurídicos, Contábeis e Financeiros dos Consórcios Públicos
Authors: Brasil Neto Lúcio Gonçalves
Published: September 2018

A Lei dos Consórcios Públicos e seu regulamento trouxeram segurança jurídica para as ações consorciadas entre entes da Federação, em especial os municípios, e que vinham acontecendo no Brasil desde a década de 1980. É só com a Constituição Federal de 1988 que pela primeira vez há menção ao instituto dos consórcios públicos. Até então, aquelas ações eram denominadas de Consórcios Administrativos e não tinham força jurídica para prolongar sua existência nem de legitimar seus atos. Ocorre que, passados cinco anos da existência de uma legislação que disciplinou a formação e atuação dos consórcios públicos, ainda não se tem notícia de uma preocupação maior por parte dos tribunais de contas no sentido de sistematizar a fiscalização desses institutos de direito público. Chegar a uma normatização específica para os consórcios públicos faz-se necessário antes, entender seus principais aspectos jurídicos e seu regime contábil e financeiro disciplinados pela Lei nº 11.107/05 e por seu regulamento.
Análise da Progressividade do Imposto sobre a Propriedade Predial e Territorial Urbana
Authors: Augusto Humberto Bayma
Published: September 2018

O presente trabalho acadêmico tem como foco principal o estudo da progressividade do IPTU (Imposto sobre a Propriedade Predial e Territorial Urbana), em face aos princípios da vedação ao confisco ou não-confiscatoriedade (art. 150, inciso IV, da Constituição da República) e capacidade contributiva (art. 145, § 1º da Constituição Brasileira). Analisa-se a aplicação da chamada progressividade “no tempo” ou “extrafiscal”, no que tange à função social da propriedade, ou seja, a sua devida utilização como instrumento de política urbana, previsto na Carta republicana de 1988, em seu art. 182, posteriormente regulado pela Lei nº 10.257/01, denominada Estatuto da Cidade. Observa-se criticamente a instituição por meio da Emenda Constitucional nº 29, de 13 de setembro de 2000, da chamada progressividade “fiscal” sobre um imposto real como o IPTU, no que concerne à sua constitucionalidade, além de examinar com minúcia o posicionamento do Supremo Tribunal Federal e da doutrina abalizada sobre os referidos temas.
A Ética como Elemento de Controle em Tempos de Responsabilidade Fiscal
Authors: Taveira Junior Rubens Silveira
Published: September 2018

Pretende-se com o presente trabalho ampliar o conceito de ética fiscal, não o diferenciando de moralidade fiscal, ao se preconizar que valores devem ser priorizados pelos agentes públicos que tenham no exercício de funções atribuições de cunho financeiro, especialmente aquelas como elaboração, proposição e companhamento das leis orçamentárias; definição de políticas públicas para a efetivação de direitos sociais, bem como as inerentes ao gasto público. É de fundamental importância para tal mister, uma mudança de paradigma na atuação de tais agentes, os quais deverão priorizar a ética ao escolherem valores que visem a uma elevação dos níveis de cidadania. Nesse sentido, sobreleva-se a importância da Lei de Responsabilidade Fiscal – LRF, a qual normatizou valores, como o da transparência, justamente no intento de tornar mais ético o atuar dos gestores públicos.
A Excepcionalidade Constitucional do Estado-Empresário Brasileiro
Authors: Santos Cristiana Espírito Santo Rodrigues
Published: September 2018

A exploração direta de atividade econômica pelo Estado, na condição de empresário, tem constitucionalmente um caráter excepcional. A Constituição Federal de 1988 elegeu a livre iniciativa como princípio fundante da ordem econômica, cabendo ao Estado situações excepcionais de atuação direta, apenas quando presentes as hipóteses descritas no artigo 173, de imperativos da segurança nacional ou relevante interesse público. O Estado-empresário, assim, foi preterido pelo Estado-regulador, na nova ordem econômica brasileira.
Soluções Proporcionadas pelo RDC para a Política Desenvolvimentista do Governo Federal
Authors: Ramos Leonardo Teixeira
Published: September 2018

O Governo Federal, na ânsia de promover uma politica desenvolvimentista, pretendendo realizar obras de grande vulto, como as da copa do Mundo, das Olimpíadas e do Programa de Aceleração do crescimento – PAC, elaborou normativos, inclusive na Lei de Diretrizes Orçamentárias – LDO, a fim de flexibilizar e viabilizar a execução destas obras. Em meio a nova legislação, surge o RDC – Regime Diferencial de Contratações, com a utilização de diversos elementos da Lei de Licitações, bem como da Lei do Pregão, em situações antes não permitidas. O presente artigo tem o desafio de analisar estes elementos e levantar as vantagens e desvantagens do RDC dentro do contexto atual.

Aspectos Polêmicos do Instituto da Readaptação Funcional no Âmbito da Administração Pública
Authors: Cavalcante Mário Sales
Published: September 2018

O tema da readaptação funcional tem comumente suscitado controvérsias no âmbito da Administração Pública, sendo por vezes objeto de demandas judiciais ajuizadas por servidores e empregados públicos em face dos órgãos e entidades das diversas esferas da federação. Com efeito, embora a readaptação funcional normalmente conte com previsão legislativa nos estatutos que regem o funcionalismo público dos entes federativos pátrios, não raro ocorre que sua disciplina legal seja omissa no que tange a vários aspectos importantes relacionados ao tema. Tendo em vista tal circunstância, e considerando ainda que a doutrina pátria referente à matéria é reduzida e a jurisprudência dissonante, o presente estudo visa a oferecer uma contribuição ao intérprete/aplicador do direito na elucidação de questões relevantes e polêmicas atinentes ao instituto.

Published: September 2018

A descentralização fiscal no Brasil, implementada a partir da Constituição Federal de 1988, representou significativas transformações no cenário das contas publicas do pais. Maior autonomia foi concedida as unidades subnacionais em um contexto de federalismo fiscal. Com isso, os problemas de endividamento e descontrole dos gastos públicos foram prementes. Nesse contexto, em maio de 2000, entrou em vigor a lei complementar 101/2000. Tal prerrogativa tinha como meta a orientação e o controle dos gastos públicos nas três esferas do Executivo, União, estados e municípios. Nesse contexto, e pretensão deste estudo observar o comportamento dos gastos públicos municipais no Piauí. A escolha do espaço geográfico deu-se pelo fato de ser este um dos estados do nordeste que concentram o maior numero de pequenos municípios, alem de estar economicamente entre as três menores economias da região. Os anos selecionados para a avaliação empírica foram 2001 e 2009. Alem disso, a fonte de dados que norteou o estudo e a Secretaria do Tesouro Nacional. Metodologicamente, utilizou-se uma revisão de literatura e posteriormente os dados empíricos que obtiveram tratamentos estatísticos, alem do auxilio de um modelo de regressão para robustecer mais os resultados. Os achados pela pesquisa apontam elevação dos gastos per capita pelos municípios piauienses, em todas as variaveis, alem de se observar elevacao do poder de explicacao das variáveis, gastos com Legislativo, educação e cultura e saúde e saneamento, em detrimento da redução das demais variáveis, na explicação dos gastos públicos municipais. As variáveis selecionadas ajustaram-se bem ao modelo e observou-se significância entre 1 e 5% em todos os anos.

The retrospective cross sectional study was undertaken to determine the pattern and different meth- ods of treatment of mandible fractures. Four hundred and thirty five patients with mandibular fractures were treated during the year 2014-2015. Among the patients attended with facial trauma during men- tioned period at casualty department of Dhaka Dental College hospital with the mandible fracture not associated with others facial bone fracture who were managed in this department and whose clinical record file are available in our record book were included in this study. A review of patients’ records and radiographs was conducted. Data regarding age, gender, cause of fracture, anatomic site and treatment modalities were reviewed. Data were presented by table and diagram. Age, location of fracture in table form, gender distribution, treatment in pie chart, etiology of fracture by histogram. There was higher prevalence in male (3.9:1), with occurrence peak between 21-30 years. The princi- pal causes of fracture in this study were RTA (Road Traffic Accidents) representing 54.02 %( n=235), followed by physical assault 17.24% (n=75), Fall, Sports injury, Blow by heavy objects, Tube well injury & others. The most injured sites were in decreasing order parasymphysis (26.31%) followed by angle of mandible 17.89% then symphysis, condyle, body of mandible dentoalveolar, ramus, coronoid process of mandible. Most patients of mandibular fractures were treated by closed reduction (arch bar, arch bars with intermaxillary fixation IMF,eyelet wiring& lateral compression plate). Rest of the patients were treated with open reduction ( miniplates fixation. 3D plate fixation) .Only 8.05% patients were managed by conservative approach. This study reflects patterns of mandibular fracture within the community and discuuss various methods of mandible fracture management in the department of Maxillofacial casualty in Dhaka Dental college hospital. It is hoped that assessment presented here will be valuable to government agencies and health care professionals involved in planning future programs of prevention & treatment of mandible fracture.Update Dent.

Governing Major Event Legacy: Case of the Glasgow 2014 Commonwealth Games
Authors: Sharp Briony , Finkel Rebecca
Published: September 2018

This article explores the emerging importance of planning and governance surrounding the concept of event legacy by focusing on an in-depth case study of the Glasgow 2014 Commonwealth Games. Given the long-term nature of the concept of legacy, the need for planned and thorough pre-,
during, and post-Games management is essential if legacy outcomes are to be monitored effectively. Research method employed for this study consist of in-depth interviews (n = 14) with policy makers, organizers, and local community associations who were involved with legacy planning
and implementation for the Glasgow 2014 Commonwealth Games. The findings present Glasgow's legacy approach as an advancement in the understanding of legacy governance and planning in relation to critical event management. By designing and implementing legacy governance structures at an early
stage, each stakeholder role is established and can be monitored while allowing for some flexibility within the legacy management partnerships. In addition, the notion of a partnership legacy can be seen to have grown from innovative legacy governance structures, such as collaborative working
and network creation, put in place by Glasgow in the early stages of legacy planning, which can act as a model of best practice for other major event host destinations.
Unlocking Doors: Decolonizing the Design of an Art Exhibition in Zimbabwe
Authors: Zigomo Pamela , Hull Richard
Published: September 2018

Participatory event design opens up opportunities for the sustainable transformation of a community and can therefore make a valuable contribution to the field of critical event studies. This article discusses the findings from a participatory action research project developed with
a community of visual artists in Zimbabwe. The project explored how participatory event design processes could be applied to the cocreation of an art exhibition that would be used as a platform to challenge the oppressive environment Zimbabwean visual artists are working in. The design of
special events in the third sector is usually reliant on the voice of the specialist event designer or organizer who is commissioned by the funding or lead agency to develop an event intervention using risk-averse and time-efficient methods. Unfortunately, this can result in in the community
of interest having a marginalized role in the proceedings and thus they lose a much-needed connection with the event intervention and are not committed to sustaining the desired change. We argue that there is an opportunity for events professionals to increase their skills and develop emancipatory
approaches that will decolonize established event design processes and contribute to the sustainable transformation of marginalized communities.
Please Come, Sit, and Share My View
Authors: Beer Sean
Published: September 2018

Communities in general, and rural communities in particular, punctuate their lives with events that bring people together and celebrate aspects of culture. Rural communities in the UK are no exception and there is a heavily populated calendar of rural events, celebrating touchstones
such as farming, hunting, and horses. Thus, there are numerous agricultural shows, game fairs, and horse events such as gymkhanas and horse shows. Research with regard to events such as these has been limited. There is a feeling among many people in the rural community that the UK is increasingly
dominated by urban, as opposed to rural, concerns and that this cultural influence is changing the nature of many rural events. This article aims to explore and articulate some of these concerns. In order to do this an autoethnographic approach has been adopted as a method, utilizing logocentrism
as an ontological lens. I grew up immersed in the culture and traditions of rural UK. I was taken hunting and was attending horse and agricultural shows before I could walk. As a young man I worked on farms and helped organize and run rural events. As such I view(ed) the world from a perspective
that reflects my cultural upbringing. I find it difficult living in an urban dominated society where I consider rural events are increasingly urbanized to a point where the life, past and present, of the countryside becomes a sideshow. This commodification of rural life in the UK is something
that has local and global relevance, though there are ways that event organizers can address some of these concerns.
Addressing Nonresponse for Categorical Data Items Using Full Information Maximum Likelihood with Latent GOLD 5.0
Authors: Edwards Susan L. , Berzofsky Marcus E. , Biemer Paul P.
Published: September 2018

Full information maximum likelihood (FIML) is an important approach to compensating for nonresponse in data analysis. Unfortunately, only a few software packages implement FIML and even fewer have the capability to compensate for missing not at random (MNAR) nonresponse. One of these packages is Statistical Innovations’ Latent GOLD; however, the user documentation for Latent GOLD provides no mention of this capability. The purpose of this paper is to provide guidance for fitting MNAR FIML models for categorical data items using the Latent GOLD 5.0 software. By way of comparison, we also provide guidance on fitting FIML models for nonresponse missing at random (MAR) using the methods of Fuchs (1982) and Fay (1986), who incorporated item nonresponse indicators within a structural modeling framework. We compare both FIML for MAR and FIML for MNAR nonresponse models for independent and dependent variables. Also, we provide recommendations for future applications of FIML using Latent GOLD.
A Significant Overluminosity in the Transiting Brown Dwarf CWW 89Ab
Authors: Beatty Thomas G. , Morley Caroline V. , Curtis Jason L. , Burrows Adam , Davenport James R. A. , Montet Benjamin T.
Published: September 2018

We observed eclipses of the transiting brown dwarf CWW 89Ab at 3.6 and 4.5 μm using Spitzer/IRAC. The CWW 89 binary system is a member of the 3.0 ± 0.25 Gyr old open cluster Ruprecht 147 and is composed of a Sun-like primary and an early M-dwarf secondary separated by a projected distance of 25 au. CWW 89Ab has a radius of 0.937 ± 0.042

and a mass of 36.5 ± 0.1

, and is on a 5.3 day orbit about CWW 89A with a non-zero eccentricity of e = 0.19. We strongly detect the eclipses of CWW 89Ab in both Spitzer channels as δ
3.6 = 1147 ± 213 ppm and δ
4.5 = 1097 ± 225 ppm after correcting for the dilution from CWW 89B. After accounting for the irradiation that CWW 89Ab receives from its host star, these measurements imply that the brown dwarf has an internal luminosity of

. This is 16 times, or 9.3σ, higher than model predictions given the known mass, radius, and age of CWW 89Ab. As we discuss, this overluminosity is explainable neither by an inaccurate age determination, nor additional stellar heating, nor tidal heating. Instead, we suggest that the anomalous luminosity of CWW 89Ab is caused by a dayside temperature inversion—though a significant error in the evolutionary models is also a possibility. Importantly, a temperature inversion would require a superstellar C/O ratio in CWW 89Ab’s atmosphere. If this is indeed the case, it implies that CWW 89Ab is a 36.5

object that formed via core accretion processes. Finally, we use our measurement of CWW 89Ab’s orbital eccentricity, improved via these observations, to constrain the tidal quality factors of the brown dwarf and the host star CWW 89A to be

Dust Segregation in Hall-dominated Turbulent Protoplanetary Disks

Published: September 2018

Imaging of the dust continuum emitted from disks around nearby protostars reveals diverse substructure. In recent years, theoretical efforts have been intensified to investigate how far the intrinsic dynamics of protoplanetary disks (PPDs) can lead to such features. Turbulence in the realm of non-ideal magnetohydrodynamics (MHD) is one candidate for explaining the generation of zonal flows which can lead to local dust enhancements. Adopting a radially varying cylindrical disk model, and considering combinations of vertical and azimuthal initial net flux, we perform 3D non-ideal MHD simulations aimed at studying self-organization induced by the Hall effect in turbulent PPDs. To this end, new modules have been incorporated into the Nirvana-iii and FARGO3D MHD codes. We moreover include dust grains, treated in the fluid approximation, in order to study their evolution subject to the emerging zonal flows. In the regime of a dominant Hall effect, we robustly obtain large-scale organized concentrations in the vertical magnetic field that remain stable for hundreds of orbits. For disks with vertical initial net flux alone, we confirm the presence of zonal flows and vortices that introduce regions of super-Keplerian gas flow. Including a moderately strong net-azimuthal magnetic flux can significantly alter the dynamics, partially preventing the self-organization of zonal flows. For plasma beta-parameters smaller than 50, large-scale, near-axisymmetric structures develop in the vertical magnetic flux. In all cases, we demonstrate that the emerging features are capable of accumulating dust grains for a range of Stokes numbers.

We present results from a systematic selection of tidal disruption events (TDEs) in a wide-area (4800 deg2), g+R band, Intermediate Palomar Transient Factory experiment. Our selection targets typical optically selected TDEs: bright (>60% flux increase) and blue transients residing in the centers of red galaxies. Using photometric selection criteria to down-select from a total of 493 nuclear transients to a sample of 26 sources, we then use follow-up UV imaging with the Neil Gehrels Swift Telescope, ground-based optical spectroscopy, and light curve fitting to classify them as 14 Type Ia supernovae (SNe Ia), 9 highly variable active galactic nuclei (AGNs), 2 confirmed TDEs, and 1 potential core-collapse supernova. We find it possible to filter AGNs by employing a more stringent transient color cut (g − r < −0.2 mag); further, UV imaging is the best discriminator for filtering SNe, since SNe Ia can appear as blue, optically, as TDEs in their early phases. However, when UV-optical color is unavailable, higher-precision astrometry can also effectively reduce SNe contamination in the optical. Our most stringent optical photometric selection criteria yields a 4.5:1 contamination rate, allowing for a manageable number of TDE candidates for complete spectroscopic follow-up and real-time classification in the Zwicky Transient Facility era. We measure a TDE per galaxy rate of

(90% CL in Poisson statistics). This does not account for TDEs outside our selection criteria, and thus may not reflect the total TDE population, which is yet to be fully mapped.
A Catalog of 10,000 Very Metal-poor Stars from LAMOST DR3
Authors: Li Haining , Tan Kefeng , Zhao Gang
Published: September 2018

We present the result of a search for very metal-poor (VMP,

) stars in the Milky Way based on low-resolution spectra from Large sky Area Multi-Object fiber Spectroscopic Telescope (LAMOST) DR3, significantly enlarging the current candidate sample of these low-metallicity objects. The selection procedure results in a sample of 10,008 VMP stars covering a large area of sky in the Northern Hemisphere, and includes over 6800 targets brighter than V ∼ 16. This LAMOST DR3 VMP sample provides the largest number of VMP candidates to date that are sufficiently bright for follow-up high-resolution observation with 4–10 m telescopes, greatly expanding the VMP stars discovered in the northern sky, and can be used to balance the spatial distribution of VMP stars with high-resolution spectroscopic analyses. Comparison with stars having existing high-resolution analyses and Tycho Gaia Astrometric Solution parallaxes indicates that the derived stellar parameters and distance estimates are reliable. The sample reaches beyond 40 kpc in the halo, and contains over 670 candidates of extremely metal-poor (

) and ultra-metal-poor (

) stars. The distribution of V

ϕ
indicates that the sample consists of two halo components, with the retrograde component likely to be associated with the outer-halo population. A new criterion is proposed to select carbon-enhanced metal-poor (CEMP) star candidates, using line indices G1 and EGP over the range 4000 K < 

 < 7000 K, resulting in 636 CEMP candidates from the LAMOST DR3 VMP sample.
Fitting the Density Substructure of the Stellar Halo with MilkyWay@home
Authors: Weiss Jake , Newberg Heidi Jo , Newby Matthew , Desell Travis
Published: September 2018

We propose and test a method for applying statistical photometric parallax to main-sequence turnoff stars in the Sloan Digital Sky Survey (SDSS). Using simulated data, we show that if our density model is similar to the actual density distribution of our data, we can reliably determine the density model parameters of three major substructures in the Milky Way halo using the computational resources available on MilkyWay@home (a 20-parameter fit). We fit the stellar density in SDSS stripe 19 with a smooth stellar spheroid component and three major streams. One of these streams is consistent with the Sagittarius tidal stream at 21.1 kpc away, one is consistent with the trailing tail of the Sagittarius tidal stream in the north Galactic cap at 48 kpc away, and one is possibly part of the Virgo Overdensity at 6 kpc away. We find the 1σ widths of these three streams to be 1.0 kpc, 17.6 kpc, and 6.1 kpc, respectively. The width of the trailing tail is extremely wide (41 kpc full width at half maximum). This large width could have implications for the shape of the Milky Way dark matter halo. The width of the Virgo Overdensity-like structure is consistent with what we might expect for a “cloudlike” structure; analysis of additional stripes of data are needed to outline the full extent of this structure and confirm its association with the Virgo Overdensity.
Time Stamps of Vertical Phase Mixing in the Galactic Disk from LAMOST/Gaia Stars

Published: September 2018

The perturbation mechanism of the Galactic disk is a long-standing puzzle. The imprints from perturbations provide important diagnostics concerning the disk’s formation and evolution. Here we try to constrain when the vertical perturbation took place in the disk by tracking the phase-mixing history. First, we clearly depict the spiral structures of radial (v

R
) and azimuthal (v

ϕ
) velocities in the phase space of the vertical position and velocity (z–v

z
) with 723,871 Large Sky Area Multi-Object Fiber Spectroscopic Telescope/Gaia combined stars. Then, we investigate the variation of the spirals with stellar age (τ) by dividing the sample into seven stellar age bins. Finally, we find that the spirals explicitly exist in all of the bins, even in the bin of τ < 0.5 Gyr, except for the bin of τ > 6.0 Gyr. This constrains the vertical perturbation to starting probably no later than 0.5 Gyr ago. But we cannot rule out the possibility that the young stars (τ < 0.5 Gyr) inherit the oscillations from the perturbed interstellar medium from where they were born. This study provides some important observational evidences to understand the disk perturbation mechanisms, and even the formation and evolution of our Galaxy.
High Spectral Resolution Observations toward Orion BN at 6 μm: No Evidence for Hot Water

Published: September 2018

The Becklin–Neugebauer (BN) object in Orion has a large proper motion and radial velocity with respect to the gas and other stars in the region where it is presumed to have formed. Multiple dynamical interaction scenarios have been proposed to explain this motion. In one case BN is thought to have interacted with stars in the Trapezium cluster, while in another it is thought to have interacted with source I while deeply embedded in molecular gas. If there is dense gas that has been retained in close proximity to BN, it may be evidence that the latter scenario is favored. We observed BN at high spectral resolution in three windows near 6 μm using the Echelon-Cross-Echelle Spectrograph on board the Stratospheric Observatory for Infrared Astronomy targeting the ν
2 vibrational band of H2O. Absorption from only three transitions of H2O is detected, and through kinematic analysis is associated with cool, dense foreground gas, not BN itself. We find no evidence for H2O absorption or emission at the systemic velocity of BN.
A reply to “Ranging Behavior Drives Parasite Richness: A More Parsimonious Hypothesis”
Authors: Charpentier Marie , Kappeler Peter
Published: September 2018

This preprint has been reviewed and recommended by Peer Community In Ecology (https://dx.doi.org/10.24072/pci.ecology.100001).

In a recent article, Bicca-Marques and Calegaro-Marques [Bicca-Marques JC, Calegaro-Marques C (2016) Ranging behavior drives parasite richness: A more parsimonious hypothesis. American Journal of Primatology 78: 923–927.] discussed the putative assumptions related to an interpretation we provided regarding an observed positive relationship between weekly averaged parasite richness of a group of mandrills (Mandrillussphinx) and their daily path lengths (DPL), published earlier in the same journal [Brockmeyer T, Kappeler PM, Willaume E, Benoit L, Mboumba S, Charpentier MJE (2015) Social organization and space use of a wild mandrill (Mandrillussphinx) group. American Journal of Primatology 77: 1036–1048.]. In our article, we proposed, inter alia, that “the daily travels of mandrills could be seen as a way to escape contaminated habitats on a local scale”. In their article, Bicca-Marques and Calegaro-Marques proposed an alternative mechanism that they considered to be more parsimonious. In their view, increased DPL also increases exposure to novel parasites from the environment. In other words, while we proposed that elevated DPL may be a consequence of elevated parasite richness, they viewed it as a cause. We are happy to see that our study attracted so much interest that it evoked a public comment. We are also grateful to Bicca-Marques and Calegaro-Marques for pointing out an obvious alternative scenario that we failed to discuss and for laying out several key factors and assumptions that should be addressed by future studies examining the links between parasite risk and group ranging. We use this opportunity to advance this discourse by responding to some of the criticisms raised in their discussion of our article. In this reply, we briefly contextualize the main object of criticism. We then discuss the putative parsimony of the two competing scenarios.
Étudier le care en infrastructure
Authors: Stiefel Léa
Published: September 2018

S’inscrivant dans le champ des Infrastructure Studies initié par la sociologue des sciences et des techniques Susan Leigh Star, l’article propose d’entrer dans les coulisses d’une infrastructure spécifique, une biobanque hospitalière, et de suivre gestes à gestes le travail de ses agents opérationnels, assistants médicaux et techniciens de laboratoire. Il propose ce faisant et dans un premier temps une mise à l’épreuve de la notion de care telle que théorisée par la philosophe Maria Puig de la Bellacasa à la suite des travaux de Bruno Latour et de sa notion de matters of concern. La spécificité de cette notion (care) étant d’interroger notre responsabilité face au devenir de la « chose » que nous étudions (qui est aussi la chose que nous construisons et que nous habitons), l’article propose dès lors d’initier dans un second temps un « style » d’enquête et de compte rendu d’enquête alternatif (alternatif en tant qu’altération du modèle classique), portant un care de forme symétrique à celui qu’ont manifesté ses enquêtés.

Effects of Highlighting Text on the Reading Ability of Children with Developmental Dyslexia: A Pilot Study
Authors: Ikeshita Hanae , Yamaguchi Sho , Morioka Toyoshi , Yamazoe Takashi
Published: September 2018

Digital texts can be made accessible to children with developmental dyslexia by presenting them in a simplified layout, using suitable fonts, or using text highlighting that is synchronized with audio. However, the impact of this last method on readability (as measured by eye movement) for children with developmental dyslexia remains unknown; it is unclear whether the color and length of text highlighting influences readability. We examined these issues in two experiments with seven children with developmental dyslexia (aged 7–14 years). In the first experiment, we clarified the relation between readability and text highlighting with synchronous audio by measuring the eye movements of children with developmental dyslexia. Readability was determined using the frequency of eye fixations. In the second experiment, we determined which styles of text highlighting best supported digital text reading among children with developmental dyslexia. Digital texts were created using different text highlighting colors and band lengths, and then were read using Apple iBooks on a 9.7-inch Apple iPad Air. We observed that children with developmental dyslexia found it easier to read along when audio was synchronized with text highlighting, particularly for the highlighting style that used a blue band for whole sentences. The second experiment showed that children with developmental dyslexia found it particularly easy to read digital texts that were highlighted with blue or yellow bands, both for single sentences and for single words. The method of presenting visual information for reading might help children with developmental dyslexia read more easily.
A Framework for Evaluating Tablet-based Educational Applications for Primary School Levels in Thailand
Authors: Nang Hsu Mon Pyae , Harfield Antony
Published: September 2018

When it comes to the use of mobile technology in the classroom, one of the major challenges for the teacher is finding suitable applications that appropriately match the topic of study. In most areas of education there are tools for evaluating teaching materials, but there are few tools for evaluating mobile technology in the classroom. The lack of evaluation methods means that for teachers, who are increasingly using tablets in the primary level classrooms, the results can be “hit or miss”. The aim of the study is to propose and describe a new framework that enables primary school teachers to evaluate tablet-based games effectively. The proposed framework is adapted from the four-dimensional framework (FDF). Thereby, supporting teachers in the choice of suitable tablet-based games to use in their classrooms that balance the essential aspects of student engagement (or playability) and learning achievement. A small case study is carried out based on the evaluation of 30 iPads STEM applications. The proposed framework can predict the initial pitfalls of technical and design issues in applications before class use. The successfully evaluated applications are used for the experiment at primary school in Thailand. The improvement of students’ learning skill, behavioral outcomes, and teachers’ perspectives are not considered in this study.
A Preliminary Investigation into the Usability of Force Touch Interaction in a Mobile Context
Authors: Murano Pietro , Ali Rao Muhammad Danial
Published: September 2018

This paper details a preliminary evaluation into the usability and universal design of force touch interaction with older users as recently introduced into the Apple iOS9 operating system. The evaluation involved a small group of older users and two typical smartphone tasks. The tasks involved increasing font size and rotating an image on an Apple iPhone with iOS9 installed. The study recorded task times and semi-structured interview responses. The overall results indicated that the new force touch feature can gain good acceptance from older users, but that there were some usability and universal design problems with the feature which hampered the potential of full acceptance by older users.
