Excavation of Red Squirrel (Tamiasciurus hudsonicus) Middens by Bears (Ursus spp.) in Limber Pine (Pinus flexilis) Habitat in Banff National Park, Alberta
Authors: Hamer David
Published: March 2017

Bears (Ursus spp.) in North America eat the seeds of several pines (Pinus spp.), including Limber Pine (P. flexilis E. James). Information on use of Limber Pine in Canada is limited to a report of three bear scats containing pine seeds found in Limber Pine stands of southwestern Alberta. After my preliminary fieldwork in Banff National Park revealed that bears were eating seeds of Limber Pine there, I conducted a field study in 2014–2015 to assess this use. Because bears typically obtain pine seeds from cone caches (middens) made by Red Squirrels (Tamiasciurus hudsonicus), I described the abundance, habitat characteristics, and use by bears of Red Squirrel middens in and adjacent to Limber Pine stands at six study sites. On Bow River escarpments, I found abundant Limber Pines (basal area 1–9 m2/ha) and middens (0.8 middens/ha, standard deviation [SD] 0.2). Of 24 middens, 13 (54%) had been excavated by bears, and three bear scats composed of pine seeds were found beside middens. Although Limber Pines occurred on steep, xeric, windswept slopes (mean 28°, SD 3), middens occurred on moderate slopes (mean 12°, SD 3) in escarpment gullies and at the toe of slopes in forests of other species, particularly Douglas-fir (Pseudotsuga menziesii). At the five other study sites, I found little or no use of Limber Pine seeds by bears, suggesting that Limber Pine habitat may be little used by bears unless the pines are interspersed with (non-Limber Pine) habitat with greater forest cover and less-steep slopes where squirrels establish middens. These observations provide managers with an additional piece of information regarding potential drivers of bear activity in the human-dominated landscape of Banff National Park’s lower Bow Valley.
Exploring the Adaptive Significance of Five Types of Puma (Puma concolor) Vocalizations
Authors: Allen Maximilian L , Wang Yiwei , Wilmers Christopher C
Published: March 2017

Communication is a central component of animal behaviour, yet communicative behaviours are poorly studied due to their complexity and varied functions. Pumas (Puma concolor) are wide-ranging, solitary felids that primarily use indirect cues (e.g., scent marking) for communication. Because these cryptic carnivores are rarely observed directly, little is known about their vocalizations in the wild. We recorded a variety of Puma vocalizations among females and family groups using motion-triggered video cameras and then attempted to understand the function of each vocalization. We found two categories of vocalizations: 1) attention-attracting (caterwauling and mewing), and 2) calls (contact, agitated, and alarm). Vocalizations to attract attention ranged across broad frequencies. Contact, agitated, and alarm calls are narrow-frequency vocalizations that varied in intensity and were used to communicate with nearby conspecifics. Vocal communication entails risk, and while some Puma vocalizations may provide benefits that outweigh their risk, others are structured to limit detection and risk. These observations highlight the importance of the structure of vocalizations used during different behaviours to understand their adaptive significance.
Behavioural Changes in Belugas (Delphinapterus leucas) During a Killer Whale (Orcinus orca) Attack in Southwest Hudson Bay
Authors: Westdal Kristin H , Davies Jeremy , McPherson Andy , Orr Jack , Ferguson Steven H
Published: March 2017

Killer Whales (Orcinus orca) were observed on 4 August 2012 attacking Belugas (Delphinapterus leucas) at high tide near the mouth of the Seal River (59°9'19"N, 94°45'28"W) in southwest Hudson Bay, near the location where six Belugas had been fitted with satellite transmitters three weeks earlier. The distribution of Belugas was analyzed before, during, and after the attack. In the presence of Killer Whales, the six Belugas altered their behaviour by reducing their combined range size from 285 km2 four days before the attack to 172 km2 on the day of the attack. Their range more than tripled, to 655 km2, in the days immediately following the attack before returning to the pre-attack size. Following the attack, the tagged Belugas expanded their range northward, going from a mean pre-attack distance of 9.4 km from the attack site to a maximum of 23.5 km. Visual observations of Belugas clumping together and moving toward shore corroborated satellite data. This evasive behaviour by Belugas was different from that reported for Narwhals (Monodon monoceros) suggesting that the two monodontid species may have evolved different survival strategies related to the risk of Killer Whale predation. With predicted changes to Arctic sea ice, the summeringhabitat of Belugas will be available to their main predator for longer periods. A better understanding of Beluga behaviour and risk of predation is required for Beluga conservation and stock management.
Formulación de una propuesta metodológica para la gestión integral de residuos químicos peligrosos en instituciones de educación superior
Authors: Vera Solano Javier Augusto
Published: March 2017

En la Universidad de Pamplona, se formuló una propuesta metodológica para la gestión integral de los residuos químicos peligrosos con base a un plan de manejo. Para verificar el funcionamiento de la metodología, se trabajó con los laboratorios de química general, se realizó preliminarmente un diagnóstico y cuantificación total de las cantidades que allí se generaban, con el fin de poder caracterizarlos ya que esta etapa de la metodología es clave para la gestión e identificación de los residuos para su posterior tratamiento. Una vez efectuadas las primeras etapas de la metodología, se procedió a implementar los tratamientos que, disminuyeron el almacenamiento temporal de los residuos químicos, se eliminaron por medio de evaporización, encapsulamiento, y biorremediacion un 35% de los residuos generados en el año 2010. Asimismo se logró que la metodología establecida se ejecutara adecuadamente, obteniéndose resultados en el mejoramiento de la segregación y caracterización de los residuos, que contribuyó a disminuir el almacenamiento sin ningún tipo de tratamiento y control en el almacén temporal, que a largo plazo podría presentar un riesgo e impacto ambiental para la institución.

Authors: Guancha Chalapud Marcelo Alexander , Caicedo Carolina , Ruiz Eliana Marcela , Valencia Maria Fernanda
Published: March 2017

En este trabajo se desarrollaron películas a partir de diferentes mezclas de quitosano y Aloe vera (80:20, 70:30 y 60:40) con el fin de evaluar las propiedades relacionadas con la tensión superficial de la película y espesor. La proporción 80:20 presentó un aspecto homogéneo, por lo cual se utilizó en la papa criolla (Solanum phureja) como recubrimiento. Este fue aplicado por inmersión del tubérculo y posterior secado variando la temperatura entre 40 °C a 70 °C con humedad relativa constante (H.R. 80%) durante 48 h. Se determinaron los parámetros colorimétricos CIELab, pérdida de peso y de carotenoides totales para cada tratamiento. Se utilizó un diseño aleatorizado simple para un total de 24 h por tratamiento. Cabe mencionar, que la cinética para las variables de estudio encontradas fue de orden cero, es decir, que el cambio de las propiedades depende exclusivamente del tiempo. La aplicación de recubrimiento a base de quitosano y Aloe vera en papa criolla permitió conservar el contenido de carotenoides totales hasta en un 70% en comparación con las muestras sin recubrimiento.

La mineralogía de procesos es una herramienta que ofrece información de gran utilidad para la modificación de procesos de obtención de oro para mejorar su eficiencia. El objetivo de este trabajo fue evaluar la mineralogía y la oxidación del mineral en el proceso de lixiviación de oro a partir de muestras de mineral aurífero refractario con soluciones de tiosulfato mediante técnicas analíticas como la Microscopía Óptica de Luz Plana Polarizada (MOLPP), Tratamiento Digital de Imágenes TDI, Microscopía Electrónica de Barrido (SEM/EDS) y Difracción de Rayos X (DRX). La caracterización mineralógica previa al proceso de lixiviación reveló asociación, tamaño y forma de ocurrencia de cada una de las fases minerales, encontrándose que el mineral empleado estaba compuesto principalmente por pirita en cristales inequigranulares y subhedrales (58% de la muestra); cristales de galena (15% de la muestra); cristales de esfalerita, calcopirita y arsenopirita (7% de la muestra);menos del 1% de oro libre y fases de aluminosilicatos (19% de la muestra). Ensayos al fuego mostraron 59 g/ton de oro y 70 g/ton de plata. Luego del proceso de lixiviación se encontró acumulación de granos individuales de pirita con surcos de corrosión, disminución de su tamaño de partícula, así como la disolución de las fases acompañantes:esfalerita, calcopirita, galena y arsenopirita. No se observó la presencia de cobre precipitado. Fue necesario realizar un pretratamiento oxidante del mineral, seguido por una lixiviación se logró una liberación de oro hasta del 82%. La caracterización mineralógica permitió definir condiciones adecuadas para la recuperación de oro.

Published: March 2017

Algunos ensayos tradicionales como la resistencia a la compresión, porosidad total, infiltración de agua, entre otros, resultan útiles a la hora de realizar un análisis de patologías en concretos que han sido atacados por agentes agresores, los cuales van en contra de su durabilidad. Sin embargo, estas pruebas clásicas carecen de herramientas para analizar cómo fue el cambio estructural e interno de la muestra después de ser atacada. Lo que evidencia la necesidad de pensar en otras alternativas y tener en cuenta herramientas más directas como la microscopía, la cual permite hacer un análisis completo tanto macro como micro acerca de la mineralogía, estructura y textura, observando en detalle la composición, fracturas, alteraciones, deformaciones y señales particulares de las muestras. Así,en este trabajo se presenta la aplicabilidad de la petrografía mediante microscopía óptica convencional en el estudio de la degradación del concreto producida por el ataque de agentes agresores. Se muestran resultados como el cambio de color en los agregados, distorsión entre contactos de grano, y cambios en la isotropía de la matriz cementante ante el ataque por fuego. Formación de fases secundarias producto del reemplazo de iones en la matriz que generan fracturamiento y expansión en las probetas expuestas a ataques por sulfato. La aparición de nuevas fases entre la matriz y los agregados y en las fracturas para las muestras sometidas a reacción álcali-sílice. Además, se pudo correlacionar todas estas transformaciones petrográficas con las pérdidas de desempeño mecánico de los concretos.

Élaboration d’indicateurs pour l’évaluation des collectivités-amies des aînés au Canada : démarche et résultats
Authors: Orpana Heather , Chawla M. , Gallagher E. , Escaravage E.
Published: March 2017

Introduction

En 2006, l’Organisation mondiale de la Santé (OMS) a lancé le projet mondial
« Villes-amies des aînés » afin de favoriser un vieillissement actif. Si un grand nombre
d’initiatives « amies des aînés » ont été mises en oeuvre au Canada, on dispose de peu
d’information sur l’efficacité et les résultats des initiatives des collectivités-amies des
aînés (CAA). En outre, les intervenants affirment qu’ils n’ont pas la capacité et les outils
nécessaires pour élaborer et réaliser des évaluations relatives à leurs initiatives de CAA.
Afin de pallier ces lacunes, l’Agence de la santé publique du Canada a mis au point des
indicateurs pour l’évaluation des initiatives de CAA dans de nombreuses collectivités
canadiennes. Ces indicateurs, destinés à répondre aux différents besoins des collectivités,
ne sont pas conçus pour faire l’évaluation de répercussions collectives ou pour rendre
possible une comparaison entre collectivités.

Méthodologie

Une démarche de consultation itérative fondée sur des données probantes
a été employée pour l’élaboration d’indicateurs relatifs aux CAA. Elle a nécessité
une revue de la littérature et une analyse du contexte. Deux rondes de consultation
auprès d’experts et d’intervenants clés ont été menées, ce qui a permis de classer les
indicateurs potentiels en fonction de leur importance, de leur capacité à être mis en
pratique et de leur faisabilité. Une liste définitive d’indicateurs et de mesures potentielles
a ensuite été mise au point, en fonction des résultats de ces consultations et de
considérations clés relatives aux politiques.

Résultats

Trente-neuf indicateurs répartis en huit domaines relevant des CAA et quatre
indicateurs relevant des résultats liés à la santé et aux conditions sociales à long terme
ont été sélectionnés. Tous sont conformes à l’objectif énoncé, à savoir l’évaluation des
initiatives de CAA à l’échelon local. Un guide convivial est disponible pour soutenir et
diffuser ce travail.

Conclusion

Les indicateurs de CAA sont susceptibles d’aider les collectivités à
procéder à l’évaluation de leurs initiatives amies des aînés, ce qui constitue la dernière
étape du cycle des jalons pancanadiens des CAA. Les collectivités sont en effet encouragées
à améliorer leurs initiatives amies des aînés à partir de l’évaluation de leurs résultats,
afin d’en faire profiter un large éventail de Canadiens.
Mana-ā-kī(tanga) and Tourism in Aotearoa
Authors: Martin Frances Kahui
Published: March 2017

The main focus of this article will discuss mana-ā-kī(tanga) and the tourism industry in Aotearoa (New Zealand). It will specifically investigate the interpretation of mana-ā-kī(tanga). Mana-ā-kī(tanga) does not discriminate between people and it is a selfless and unconditional act, with no preconceived expectations. I learned that mana-ā-kī(tanga) could be shared, not only amongst whānau (family) but also with manuhiri (visitor), including those from overseas. It is no wonder therefore that the term mana-ā-kī(tanga) is embraced and promoted within Aotearoa, to manuhiri from foreign shores. The term mana-ā-kī(tanga) is widely understood in the tourism industry as hospitality and reciprocity. Hence, possible misinterpretation of mana-ā-kī(tanga) could result in this concept being used incorrectly and lead to the transgression of cultural practices, thus compromising the experiences offered by Māori tourism operators. Throughout this article there is a deliberate emphasis on the spelling of mana-ā-kī(tanga) to show the importance of mana-ā-kī (respect earned from the recognition of others). Thus, the spelling in the English alphabet of manaakitanga and manaaki is used intermittently.
He kura huna - Māori expressions of educational success
Authors: Martin Jennifer
Published: March 2017

Western values have long dominated discourse on what constitutes success and achievement in education. New Zealand’s own education system has been described as one which “... gives first priority to academic and western values of success” (Lee, 2008, p. 81). Emphasis is placed upon the individual,  academic excellence, literacy and numeracy, economic outcomes, and competence in what western society deems valid knowledge, and as such, current assessment measures are reflective of this. While such measures are accepted as ‘best practice’ for mainstream institutions, it is argued that where indigenous education is concerned, “...success also lies in more holistic ways of knowing and participating within a rich cultural context” (Bell, 2004, p.30).

Situated in a Māori world view, this paper considers success through a Māori lens. It is argued that Māori notions of success are not only premised upon academic results, rather cultural factors are considered equally as important to knowledge and understanding of te ao Māori (Māori world view), tikanga Māori (Māori customary practices), whakapapa (genealogy), hītori (histories and tradition) and te reo Māori (the Māori language).

This paper seeks to highlight Māori expressions of educational success for Kura Kaupapa Māori (KKM) through the implementation of a holistic approach to education, underpinned by the guiding philosophy, Te Aho Matua.

This paper will draw on my doctoral research. Graduates experiences are an integral part of this paper and research, as they give voice and validity to KKM educational success.

The world has become more interconnected which has changed the way we communicate (Steinfeldt et al., 2010).  As technology has continually developed allowing instant online publication, an increasing abundance of opinionated discourse has appeared on the worldwide web (Chelaru, Altingovde, Siersdorfer & Nejdl, 2012).  From blogs that disseminate political ideologies, to hair and makeup tutorials, the internet has become a medium that facilitates unfiltered instantaneous communication to a potentially global audience.  While most users of internet services utilise the technology to engage in civilised dialogue, it does not require much effort to locate capricious behaviour in the anonymised online environment.
I sing of Te Aitu o Te Rangi and the power of song to rejuvenate the principles, values and philosophy of Mana Wahine
Authors: Smith Sophronia
Published: March 2017

I will sing of my tipuna wahine, Te Aitu o Te Rangi, daughter of Rangitane o Wairarapa chief, Te Whatahoronui. She was a beautiful young fourteen year old when the Ngāti Toa Chief Te Rauparaha successfully conquered the area and took her as a slave wife. Two years later Te Aitu and John Jury escaped Kapiti Island, where she was held captive and journeyed on a two man whaling boat back to Wairarapa. She was courageous amidst impending death on the turbulent waters of Wairarapa. She was also the mother of one of the most prolific writers, researchers and academic from Wairarapa, Hoani Te Whatahoro Jury, whose work ensured the preservation of knowledge regarding kauwae runga kauwae raro. In performing original contemporary composition, I celebrate the accomplishments of Te Aitu o Te Rangi, a Tuawahine, and I recall and embody the power of my matrilineal genealogy. Mana wahine stands strong in the spaces where feminist discourse continues to dominate, and composition provides a platform on which to reclaim and rewrite difference. My paper will look at the medium of contemporary music to provoke recognition and critique of the western archetype of the heroine, whilst at the same time advocating for social change.

Authentic Materials for Learning English: A Study on EFL Students in Aceh
Authors: Sari Diana Fauzia
Published: March 2017

This study explores the students’ opinions on the use of authentic materials and whether these materials motivate them in learning English in the classroom. Authentic materials have been claimed by many experts to give a positive impact on learners’ interest to learn a foreign language (in the classroom). Therefore, this study was conducted to understand the responses of the sample students about the use of authentic texts in teaching-learning English, especially for university students in the EFL context, such as in Indonesia. The data was gathered from 50 first-year students of English. This research used a questionnaire proposed by Peacock (1997) to collect data on the use of authentic materials and motivation in the learning process. The questionnaire was distributed to the students. After analysing the data, it was found that the learners were mostly motivated by using authentic materials because they are exciting to be discussed in the class, interesting to learn and appealing to the learners. The findings in the present research appear to be similar to those from previous research studies who claim that when learners use authentic materials in the learning process, the overall class interest in learning a foreign language increases significantly.

Extracranial meningiomas may be subdivided into primary and secondary types based on absence or presence of intracranial attachments respectively. Primary sinonasal tract meningiomas are rare with unknown etiopathology and non-specific clinical presentation. Of these PEMs only 11.5% are in the nasal cavity and nasal septum. To our knowledge less than 50 cases of PEM of nasal cavity have been reported in the literature. We report a case of a 22 years old male who presented with epistaxis and increasing nasal stuffiness for the last one year.
Role of Sepsis Screening in early diagnosis of Neonatal Sepsis
Authors: Lakhey A , Shakya H
Published: March 2017

Background: Neonatal sepsis, a clinical syndrome of bacteremia with systemic signs and symptoms of infection in the first 4 weeks of life is a major cause of morbidity and mortality in newborn inborn. Early diagnosis is critical, as sepsis can progress more rapidly in neonates than in adults. An attempt was made to establish correlation between early neonatal sepsis screening & blood culture in neonates presenting with features of sepsis. The aim of this study is to assess the usefulness of sepsis screen in early diagnosis of neonatal septicemia.Materials and Methods: The study was done in Kist medical college and hospital, Nepal from October 2015 to October 2016.  Statistical correlation between early indicators of sepsis screen & blood culture (considered as gold standard) was established in clinically suspicious cases of neonatal sepsis. Results: Out of 150 cases studied, 72 were culture positive. CRP (77.8%) and immature: total neutrophils ratio (73%) showed highest sensitivity. CRP (66.7%), I/T ratio (61.5%) and micro ESR (60.2%) showed highest specificity. Positive predictive value was highest for CRP (68.2%) followed by I/T ratio (63.8%) and corrected total leukocyte count (56.2%)Conclusion: Serum CRP is the most sensitive marker of sepsis. Use of peripheral smear study and CRP can be implicated effectively as a sepsis screen for early diagnosis of neonatal sepsis. The combination of parameters yielded better results than single tests and proved to be an invaluable tool for early diagnosis of neonatal sepsis.

A chromosome‐specific recombinant inbred line (CS‐B05shRIL) population was created from a cross of TM‐1, the genetic standard line of Gossypium hirsutum L., and CS‐B05sh, a previously released interspecific chromosome substitution line in which all of the chromosome pairs are genetically similar to those of TM‐1, except for the short arm of chromosome 5, which is substituted from 3‐79 (G. barbadense L.). Four of the fifty CS‐B05shRILs were selected and released on the basis of their improved elongation ranging from 7.37 to 7.84%. The four selected RILs are identified as CS‐B05shRIL‐93 (Reg. No. GP‐1014, PI 677339), CS‐B05shRIL‐68 (Reg. No. GP‐1013, PI 677337), CS‐B05shRIL‐66 (Reg. No. GP‐1012, PI 677336), and CS‐B05shRIL‐10 (Reg. No. GP‐1011, PI 677334).The fiber properties among the CS‐B05ShRILs were compared with those of commercial cultivars DP 393 and PHY 370 WR, which had elongations of 6.86 and 6.25%. Commercial lines performed better for agronomic traits than the released lines. Fiber elongation (the ability to stretch before breaking) is a critical trait in determining yarn quality. The combination of strength and elongation in a fiber determines the energy needed to break either a fiber or a yarn. Due to changes in textile technologies, the global market demands cotton cultivars with improved potential for tensile properties. These germplasm lines are released to incorporate improved elongation genes from only the short arm of chromosome 5 of G. barbadense, thereby reducing genetic drag effect compared with the conventional method of interspecific introgression involving the whole genome.

‘YZ01‐1413’ (Reg. No. CV‐170; PI 678580) sugarcane (a complex hybrid of Saccharum spp.) was developed through cooperative research conducted by Yunnan Sugarcane Research Institute (YSRI), of Yunnan Academy of Agricultural Sciences, and Yunnan Yunzhe Technology Development Co., Ltd. It was released to growers in Yunnan Province, China, on 9 June 2014. YZ01‐1413 was selected from the cross ‘Yuetang 85‐177’ × ‘ROC10’ planned by YSRI and crossed at the Yacheng Sugarcane Breeding Station of Guangzhou Sugar Industry Research Institute, Yacheng, Hainan Province of mainland China in December 2000. The female parent (Yuetang 85‐177) is a cultivar developed by the Guangzhou Sugar Industry Research Institute. The male parent (ROC10) is a cultivar developed by the Taiwan Sugar Research Institute. YZ01‐1413 was selected from a five‐stage selection program in YSRI and tested in the 11th Yunnan Regional Trial of Sugarcane Varieties at five locations of Yunnan Province for 2 yr. YZ01‐1413 was released by the Yunnan Committee of Crop Variety Release because of its higher cane yield compared with reference cultivars ROC10 and ROC22 (25.8 and 8.4%, respectively), higher sugar yield compared with ROC10 and ROC22 (25.5 and 7.4%, respectively), tolerance to drought, and high resistance to smut.
Towards a morphosyntactic analysis of -ish
Authors: Oltra-Massuet Isabel
Published: March 2017

This article deals with the morphosyntactic and semantic properties of the adjectives derived with the English morpheme -ish. The main goal of the paper is to outline a morphosyntactic analysis of -ish that: (i) accounts for its cross-categorial nature, (ii) derives its surface polysemy, and (iii) is compatible with Bochnak & Csipak's (2014) recent semantic analysis of deadjectival -ish (for example, reddish) and free-standing propositional -ish (for example, I liked the movie …ish) as a metalinguistic degree operator. Focusing on the analysis of the various subtypes of bounded -ish forms, this paper develops a unified morphosyntactic approach to -ish with a single shared semantics, and suggests that the cross-categorial and polysemous nature of -ish derives from three main closely interrelated factors: (i) the source of the degree variable that -ish targets, whether syntactic, lexical, or metalinguistic; (ii) the syntactic realization site of -ish; and (iii) the late insertion of the underspecified morpheme -ish.
Pulse Propagation Models with Bands of Forbidden Frequencies or Forbidden Wavenumbers: A Consequence of Abandoning the Slowly Varying Envelope Approximation and Taking into Account Higher-Order Dispersion
Authors: Fujioka Jorge , Gómez-Rodríguez Alfredo , Espinosa-Cerón Áurea
Published: March 2017

We study linear and nonlinear pulse propagation models whose linear dispersion relations present bands of forbidden frequencies or forbidden wavenumbers. These bands are due to the interplay between higher-order dispersion and one of the terms (a second-order derivative with respect to the propagation direction) which appears when we abandon the slowly varying envelope approximation. We show that as a consequence of these forbidden bands, narrow pulses radiate in a novel and peculiar way. We also show that the nonlinear equations studied in this paper have exact soliton-like solutions of different forms, some of them being embedded solitons. The solutions obtained (of the linear as well as the nonlinear equations) are interesting since several arguments suggest that the Cauchy problems for these equations are ill-posed, and therefore the specification of the initial conditions is a delicate issue. It is also shown that some of these equations are related to elliptic curves, thus suggesting that these equations might be related to other fields where these curves appear, such as the theory of modular forms and Weierstrass ℘ functions, or the design of cryptographic protocols.
Influence of Urban Multi-Criteria Deprivation and Spatial Accessibility to Healthcare on Self-Reported Health
Authors: Cabrera-Barona Pablo
Published: March 2017

Self-reported health is considered a health outcome related to neighborhood characteristics. This study analyzes the influence of urban multi-criteria deprivation and spatial accessibility to healthcare on individual self-reported health from a case study carried out in the city of Quito, Ecuador. A multi-criteria deprivation index and two alternative scenarios of this index were generated. A gravity-based measure of spatial accessibility to healthcare was also calculated. The neighborhood effects of deprivation measures and spatial accessibility to healthcare on individual self-reported health were evaluated by applying multilevel models. Significant neighborhood effects were found in two of the three applied multilevel models. This study contributes evidence of neighborhood effects on health outcomes, and can support urban planners and policy-makers in the reduction of urban health-related inequalities.

We perform a spectroscopic survey of the foreground population in Orion A with MMT/Hectospec. We use these data, along with archival spectroscopic data and photometric data, to derive spectral types, extinction values, and masses for 691 stars. Using the Spitzer Space Telescope data, we characterize the disk properties of these sources. We identify 37 new transition disk (TD) objects, 1 globally depleted disk candidate, and 7 probable young debris disks. We discover an object with a mass of less than 0.018–0.030 M
⊙, which harbors a flaring disk. Using the Hα emission line, we characterize the accretion activity of the sources with disks, and confirm that the fraction of accreting TDs is lower than that of optically thick disks (46% ± 7% versus 73% ± 9%, respectively). Using kinematic data from the Sloan Digital Sky Survey and APOGEE INfrared Spectroscopy of the Young Nebulous Clusters program (IN-SYNC), we confirm that the foreground population shows similar kinematics to their local molecular clouds and other young stars in the same regions. Using the isochronal ages, we find that the foreground population has a median age of around 1–2 Myr, which is similar to that of other young stars in Orion A. Therefore, our results argue against the presence of a large and old foreground cluster in front of Orion A.

We present initial results from the first systematic survey of luminous z ∼ 5.5 quasars. Quasars at z ∼ 5.5, the post-reionization epoch, are crucial tools to explore the evolution of intergalactic medium, quasar evolution, and the early super-massive black hole growth. However, it has been very challenging to select quasars at redshifts 5.3 ≤ z ≤ 5.7 using conventional color selections, due to their similar optical colors to late-type stars, especially M dwarfs, resulting in a glaring redshift gap in quasar redshift distributions. We develop a new selection technique for z ∼ 5.5 quasars based on optical, near-IR, and mid-IR photometric data from Sloan Digital Sky Survey (SDSS), UKIRT InfraRed Deep Sky Surveys—Large Area Survey (ULAS), VISTA Hemisphere Survey (VHS), and Wide Field Infrared Survey Explorer. From our pilot observations in the SDSS-ULAS/VHS area, we have discovered 15 new quasars at 5.3 ≤ z ≤ 5.7 and 6 new lower redshift quasars, with SDSS z band magnitude brighter than 20.5. Including other two z ∼ 5.5 quasars already published in our previous work, we now construct a uniform quasar sample at 5.3 ≤ z ≤ 5.7, with 17 quasars in a ∼4800 square degree survey area. For further application in a larger survey area, we apply our selection pipeline to do a test selection by using the new wide field J-band photometric data from a preliminary version of the UKIRT Hemisphere Survey (UHS). We successfully discover the first UHS selected z ∼ 5.5 quasar.
Gas Removal in the Ursa Minor Galaxy: Linking Hydrodynamics and Chemical Evolution Models

Published: March 2017

We present results from a non-cosmological, three-dimensional hydrodynamical simulation of the gas in the dwarf spheroidal galaxy Ursa Minor. Assuming an initial baryonic-to-dark-matter ratio derived from the cosmic microwave background radiation, we evolved the galactic gas distribution over 3 Gyr, taking into account the effects of the types Ia and II supernovae. For the first time, we used in our simulation the instantaneous supernovae rates derived from a chemical evolution model applied to spectroscopic observational data of Ursa Minor. We show that the amount of gas that is lost in this process is variable with time and radius, being the highest rates observed during the initial 600 Myr in our simulation. Our results indicate that types Ia and II supernovae must be essential drivers of the gas loss in Ursa Minor galaxy (and probably in other similar dwarf galaxies), but it is ultimately the combination of galactic winds powered by these supernovae and environmental effects (e.g., ram-pressure stripping) that results in the complete removal of the gas content.

The Star Formation in Nearby Clouds (SFiNCs) project is aimed at providing a detailed study of the young stellar populations and of star cluster formation in the nearby 22 star-forming regions (SFRs) for comparison with our earlier MYStIX survey of richer, more distant clusters. As a foundation for the SFiNCs science studies, here, homogeneous data analyses of the Chandra X-ray and Spitzer mid-infrared archival SFiNCs data are described, and the resulting catalogs of over 15,300 X-ray and over 1,630,000 mid-infrared point sources are presented. On the basis of their X-ray/infrared properties and spatial distributions, nearly 8500 point sources have been identified as probable young stellar members of the SFiNCs regions. Compared to the existing X-ray/mid-infrared publications, the SFiNCs member list increases the census of YSO members by 6%–200% for individual SFRs and by 40% for the merged sample of all 22 SFiNCs SFRs.
