The stock market has become a significant role in the economy and has attracted investor's attention, as it is to generate funds and make an investment decision for companies and investors as well. Therefore, the objective of this study is to study the effect of the money supply, exchange rate, interest spread and stock market in the short and long run and volatility issue. The study employed monthly data, from January 1997 to August 2018. Method analysis is the Autoregressive distributed lag (ARDL) and GARCH model. The findings stated that the money supply, real effective exchange rate, interest spread, had a long-run effect on the performance of the stock market. Money supply and the real effective exchange rate had a positive effect on the stock market performance in the short run. Conversely, the interest spread showed a negative influent on the stock market performance in the short run. The volatility indicated a high persistence between the money supply, real effective exchange rate, interest spread and stock market (KLCI). The implication of the study is the investors or policymakers should take account the changes of interest rate and exchange rate before making stock investment or policy to stabilize the stock market performance.Keywords: Performance, Money Supply, Real Effective Exchange Rate (REER), Interest Spread
Principles and Methods of Establishing Intelligent First Order Survey Controls in a University Environment
Authors: E.A Iyi , L.K. Ugwu
Published: September 2019

Players in the physical planning and development of the environment in which we live are often accountable for levels of its progress or decline. This is because the players (planners, surveyors and other environmental managers) have greater information as well as privileged access to data that are directly or indirectly on land and its resources. This paper showcases a working document for establish- ing intelligent first order survey controls in a university environment for use in instructing students in the field of physical planning and development of the envi- ronment. The permanent site of the Enugu State University of Science and Tech- nology (ESUT) Agbani was used as a case study, where three (3) first Order con- trols were established for use. This was achieved with the use of Global Naviga- tion Satellite System (GNSS). The problem addressed was that, even though first order survey controls are very necessary for high accuracy positioning and re- search, the Enugu State University of Science and Technology (ESUT) Agbani currently has no such very reliable control points because most of those previous- ly established were second and third order controls established for instructional purposes. The project was executed with the use of GNSS for precise point posi- tioning and to measure vectors (or baselines) between two or more survey control marks in a static (or stationary) mode of operation. Data collection was through a reconnaissance survey with appropriate remote sensing and other equipment to acquire high resolution imageries for the referenced depiction of the site charac- teristics. Geo-spatial analysis including geo-referencing of critical infrastructures and other point of interest (POI) within the permanent site was achieved. With the data so collected, three points were established (one at the Administrative area, one at the Faculty of Environmental Sciences and one at the Vice Chancel- lor’s Lodge). It is recommended that staff and students make use of these Con- trols for accurate instructions on positioning of structures in the University and other environments and also for checking structural deformations.

We present here new observations of the eccentric debris ring surrounding the Gyr-old solar-type star HD 202628: at millimeter wavelengths with ALMA, at far-infrared wavelengths with Herschel, and in scattered light with the Hubble Space Telescope (HST). The ring inner edge is found to be consistent between ALMA and HST data. As radiation pressure affects small grains seen in scattered-light, the ring appears broader at optical than at millimeter wavelengths. The best fit to the ring seen with ALMA has inner and outer edges at 143.1 ± 1.7 au and 165.5 ± 1.4, respectively, and an inclination of 57.°4 ± 0.4 from face-on. The offset of the ring center of symmetry from the star allows us to quantify its eccentricity to be

. This eccentric feature is also detected in low resolution Herschel/PACS observations, under the form of a pericenter-glow. Combining the infrared and millimeter photometry, we retrieve a disk grain size distribution index of ∼−3.4, and therefore exclude in situ formation of the inferred belt-shaping perturber, for which we provide new dynamical constraints. Finally, ALMA images show four point-like sources that exceed 100 μJy, one of them being just interior to the ring. Although the presence of a background object cannot be excluded, we cannot exclude either that this source is circumplanetary material surrounding the belt-shaper, in which case degeneracies between its mass and orbital parameters could be lifted, allowing us to fully characterize such a distant planet in this mass and age regime for the very first time.
A Forward Modeling Approach to AGN Variability--Method Description and Early Applications
Authors: Sartori Lia F. , Trakhtenbrot Benny , Schawinski Kevin , Caplar Neven , Treister Ezequiel , Zhang Ce
Published: September 2019

We present a numerical framework for the variability of active galactic nuclei (AGNs), which links the variability of AGNs over a broad range of timescales and luminosities to the observed properties of the AGN population as a whole, and particularly the Eddington ratio distribution function. We implemented our framework on GPU architecture, relying on previously published time-series-generating algorithms. After extensive tests that characterize several intrinsic and numerical aspects of the simulations, we describe some applications used for current and future time-domain surveys and for the study of extremely variable sources (e.g., “changing-look” or flaring AGNs). Specifically, we define a simulation setup that reproduces the AGN variability observed in the (intermediate) Palomar Transient Factory survey and use it to forward model longer light curves of the kind that may be observed within the Large Synoptic Survey Telescope (LSST) main survey. Thanks to our efficient implementations, these simulations are able to cover, for example, over 1 Myr with a roughly weekly cadence. We envision that this framework will become highly valuable to prepare for, and best exploit, data from upcoming time-domain surveys,  such as, for example, LSST.

The interaction between the expanding supernova (SN) ejecta with the circumstellar material (CSM) that was expelled from the progenitor prior to explosion is a long-sought phenomenon, yet observational evidence is scarce. Here we confirm a new example: SN 2004dk, originally a hydrogen-poor, helium-rich Type Ib SN that reappeared as a strong

-emitting point source on narrowband

images. We present follow-up optical spectroscopy that reveals the presence of a broad

component with full width at half maximum of ∼ 290

in addition to the narrow

+[N ii] emission features from the host galaxy. Such a broad component is a clear sign of an ejecta–CSM interaction. We also present observations with the XMM-Newton Observatory, the Swift satellite, and the Chandra X-ray Observatory that span 10 days to 15 years after discovery. The detection of strong radio, X-ray, and

emission years after explosion allows various constraints to be put on pre-SN mass-loss processes. We present a wind-bubble model in which the CSM is “pre-prepared” by a fast wind interacting with a slow wind. Much of the outer density profile into which the SN explodes corresponds to no steady-state mass-loss process. We estimate that the shell of compressed slow wind material was ejected ∼1400 yr prior to explosion, perhaps during carbon burning, and that the SN shock had swept up about 0.04

Direct N-body Simulations of Tidal Disruption Rate Evolution in Unequal-mass Galaxy Mergers
Authors: Li Shuo , Berczik Peter , Chen Xian , Liu F. K. , Spurzem Rainer , Qiu Yu
Published: September 2019

The hierarchical galaxy formation model predicts supermassive black hole binaries (SMBHBs) in galactic nuclei. Due to the gas poor environment and the limited spatial resolution in observations they may hide in the center of many a galaxy. However, a close encounter of a star with one of the supermassive black holes (SMBHs) may tidally disrupt it to produce a tidal disruption event (TDE) and temporarily light up the SMBH. In a previous work, we investigated direct N-body simulations with the evolution of TDE rates of SMBHB systems in galaxy mergers of equal mass. In this work we extend the investigation to unequal-mass mergers. Our results show that, when two SMBHs are far away from each other, the TDE rate of each host galaxy is similar as in an isolated galaxy. As the two galaxies and their SMBHs separation shrink, the TDE rate increases gradually until it reaches a maximum shortly after the two SMBHs become bound. In this stage, the averaged TDE rate can be enhanced by several times to an order of magnitude relative to isolated single galaxies. Our simulations show that the dependence of the TDE accretion rate on the mass ratio in this stage can be well fitted by power-law relations for both SMBHs. After the bound SMBHB forms, the TDE rate decreases with its further evolution. We also find that in minor mergers TDEs of the secondary SMBH during and after the bound binary formation are mainly contributed by stars from the other galaxy.
Direct Calculation of Self-gravitational Force for Infinitesimally Thin Gaseous Disks Using Adaptive Mesh Refinement
Authors: Tseng 曾耀 Yao-Huan 寰 , Shang 尚 Hsien 賢 , Yen 嚴健 Chien-Chang 彰
Published: September 2019

Yen et al. advanced a direct approach for the calculation of self-gravitational force to second-order accuracy based on uniform grid discretization. This method improves the accuracy of N-body calculation using exact integration of kernel functions and employing the Fast Fourier Transform to reduce the complexity of computation to be nearly linear. This direct approach is free of artificial boundary conditions; however, the applicability is limited by the uniform discretization of grids. We report here an advancement in the direct method with the implementation of adaptive mesh refinement and maintaining second-order accuracy, which breaks the barrier set by uniform grid discretization. The adoption of graphic process units can significantly speed up the computation and make application of this method possible for the astrophysical systems of gaseous disk galaxies and protoplanetary disks.
The Observability of Vortex-driven Spiral Arms in Protoplanetary Disks: Basic Spiral Properties
Authors: Huang 黄 Pinghui 平辉 , Dong 董 Ruobing 若冰 , Li 李 Hui 晖 , Li 李 Shengtai 胜台 , Ji 季 Jianghui 江徽
Published: September 2019

Some circumstellar disks are observed to show prominent spiral arms in infrared scattered light or (sub-)millimeter dust continuum. The spirals might be formed from self-gravity, shadows, or planet–disk interactions. Recently, it was hypothesized that massive vortices can drive spiral arms in protoplanetary disks in a way analogous to planets. In this paper, we study the basic properties of vortex-driven spirals by the Rossby Wave Instability in 2D hydrodynamics simulations. We study how the surface density contrast, the number, and the shape of vortex-driven spirals depend on the properties of the vortex. We also compare vortex-driven spirals with those induced by planets. The surface density contrast of vortex-driven spirals in our simulations are comparable to those driven by a sub-thermal mass planet, typically a few to a few tens of Earth masses. In addition, different from the latter, the former is not sensitive to the mass of the vortex. Vortex-driven spiral arms are not expected to be detectable in current scattered light observations, and the prominent spirals observed in scattered light in a few protoplanetary disks, such as SAO 206462 (HD 135344B), MWC 758, and LkHα 330, are unlikely to be induced by the candidate vortices in them.
Revisiting the Strongest Martian X-Ray Halo Observed by XMM-Newton on 2003 November 19–21

Published: September 2019

On 2003 November 20–21, when the most intense geomagnetic storm during solar cycle 23 was observed at Earth, XMM-Newton recorded the strongest Martian X-ray halo hitherto. The strongest Martian X-ray halo has been suggested to be caused by the unusual solar wind, but no direct evidence has been given in previous studies. Here, we examined the Mars Global Surveyor (MGS) observations and found unambiguous evidence of unusual solar wind impact during that XMM-Newton observation: the whole induced magnetosphere of Mars was highly compressed. By comparing the solar wind dynamic pressure estimated at Mars from MGS observation and that predicted by different solar wind propagation models, it is further supported that the interplanetary condition during the XMM-Newton observation is not related to the quiet solar wind, but to solar wind disturbances with enhanced dynamic pressure, which is probably related to the interplanetary coronal mass ejection observed at Earth on 2003 November 20. A solar energetic particle event also impacted Mars during the XMM-Newton observation and lasted for several days. Its impact on the production of the X-ray emission from Mars may be worth investigating in the future.

Crocidosema nitsugaisp. nov. (Lepidoptera, Tortricidae, Olethreutinae, Eucosmini) is described and illustrated from the Andes of northern Chile based on adults obtained from larvae collected on leaves, flowers and unripe fruits and seeds of Lupinus oreophilus Phil. (Fabaceae). This represents the first record of insect herbivory on this Chilean endemic perennial herb. The genitalia morphology of C. nitsugai suggests a close evolutionary relationship with two congenerics from high elevation environments of the Ecuadorian and Peruvian Andes.
Epidemiological Transition and the Wealth of Nations: the Case of HIV/AIDS in a Microsimulation Model
Authors: Arrighi Yves , Ventelou Bruno
Published: September 2019

Cet article vise à décomposer l’effet de programmes curatifs sur la performance macroéconomique de pays en développement en phase de transition épidémiologique. Il est largement admis dans la littérature que les programmes d’accès aux soins génèrent des gains de productivité chez les travailleurs en mauvaise santé. Cependant, ces programmes modifient par nature la taille et la composition de la population active en augmentant la proportion d’individus souffrant de maladies chroniques, atténuant ainsi l’effet sur la productivité moyenne. Après avoir défini les conditions théoriques nécessaires à ce que cet effet de structure supplante l’effet productif de l’accès aux soins, nous transposons cette investigation au cas des programmes de traitements antirétroviraux dans trois pays d’Afrique subsaharienne touchés par le VIH/SIDA. Un modèle de microsimulation est utilisé pour générer ex-ante les trajectoires de santé et de production d’individus représentatifs, selon qu’ils aient ou non accès aux antirétroviraux. Nous utilisons le modèle pour générer un « contrefactuel » (en l’absence de l’effet de composition) et constatons que l’effet productif l’emporte sur l’effet épidémiologique négatif. Bien entendu, cette approche n’est qu’un indicateur des performances économiques et, en tout état de cause, ne doit pas constituer un critère de décision sur la nécessité éthique de l’accès aux soins.

Capelães na marinha mercante portuguesa: engajamento e perfis profissionais (séculos XVIII e XÌX)
Authors: Rodrigues Jaime
Published: September 2019

Entre las diferentes profesiones encontradas en las fuentes que se refieren a la marina mercante portuguesa en los tiempos modernos, los capellanes destacan como profesionales cuya formación fue forjada exclusivamente en tierra. Los capellanes fueron responsables de la ayuda espiritual de la tripulación. El objetivo de este artículo es definir tanto las funciones como los roles de estos hombres. Seguidamente, se propone perfilar breves biografías profesionales de algunos capellanes que viajaron desde el puerto de Lisboa a los dominios de Ultramar, especialmente de aquellos que lo hicieron a la América portuguesa entre mediados del siglo XVIII y las primeras décadas del XIX. Se trata así de enfatizar la antigüedad de la presencia de los sacerdotes católicos a bordo de los navíos portugueses.

[pt] Em meio às diversas profissões encontradas nas fontes referentes à marinha mercante lusa na época moderna, os capelães destacam-se como um ofício cuja formação se dava exclusivamente em terra, cabendo a eles o socorro espiritual dos tripulantes. A intenção aqui é definir suas funções e o perfil desses homens, bem como traçar breves biografias profissionais de capelães em circulação desde o porto de Lisboa até os domínios ultramarinos, sobretudo os da América portuguesa, entre meados do século XVIII e as primeiras décadas do século XIX, com recuos para temporalidades anteriores a fim de enfatizar a antiguidade da presença de sacerdotes católicos a bordo.
De América a Asia. El «otro viaje» de Alexander von Humboldt
Authors: Lubrich Oliver
Published: September 2019

En 1829 Alexander von Humboldt emprendió una expedición a Asia. Este segundo gran viaje del científico alemán fue complementario, en muchos sentidos, de su más conocido viaje a América, que realizó entre 1799 y 1804. En Rusia, Humboldt viajó y trabajó bajo una fuerte presión política. En su Asie centrale (1843) se sirve de técnicas sutiles y de una crítica indirecta. Humboldt concluyó que, en una economía de monopolios estatales, generar energía era poco eficiente y causa de la destrucción del medio ambiente y del cambio climático.

Reading 1 Corinthians 7:10–11 in the context of intimate partner violence in Nigeria
Authors: Ademiluka Solomon O.
Published: September 2019

In Nigeria, most of the mainline churches forbid divorce and remarriage, and one of the passages most popularly quoted in support of this doctrine is 1 Corinthians 7:10–11. The traditional interpretation teaches that marriage is ‘for better, for worse’ and should be between one man and one woman for life. In view of the fact that this mode of interpretation is capable of enhancing the already high rate of domestic violence, this work examines the text in the context of intimate partner violence (IPV) in Nigeria. Applying the analytical and exegetical methods, the essay investigates the possible correlation between the doctrine of no divorce and IPV. The research found that when understood against its specific context, 1 Corinthians 7:10–11 permits divorce and remarriage on grounds of adultery, and allows a deserted Christian spouse to remarry. It can also be deduced from the chapter that when IPV poses threat to life, divorce may be the appropriate response, and the affected spouses are free to remarry. In this way, a proper understanding of the passage can go a long way to reducing the rate of domestic violence in Nigeria. It is noteworthy, however, that the overall intent of the text is to protect marriage as a permanent institution, hence even when divorce has taken place, the church and concerned couples should still seek reconciliation.Intradisciplinary and/or interdisciplinary implications: The work employs the analytical approach for the investigation of the correlation between the doctrine of no divorce and IPV, and the exegetical method to the study of 1 Corinthians 7:10–11 and other related texts.
Exercise in Congenital Heart Disease
Authors: Powell Adam W.
Published: September 2019

Congenital heart disease (CHD) patients tend to exercise less than their peers without heart disease. These patients often have exercise hesitancy or are not appropriately encouraged to exercise by their primary cardiologists. Regular exercise in the CHD population has been shown to increase fitness and lessen the incidence of obesity. There are positive psychosocial benefits of regular exercise including decreased mood disorders, improved academic performance, and ultimately improved quality of life. As physical activity is increasingly emphasized, a purposeful approach utilizing cardiopulmonary exercise testing for risk stratification and establishment of a baseline level of fitness is often helpful. Once exercise testing is complete, cardiopulmonary rehabilitation has been shown to improve measures of physical and mental fitness and should be considered in CHD patients in need of assistance with exercise.
Early Repolarization with a Constant ST-segment Elevation in Leads II, III, and AVF

Published: September 2019

Background:

A recent scientific statement from the American Heart Association included ST-segment elevation in the absence of chest pain in the definition of early repolarization (ER). ST-elevation at J-point termination (Jt)-point was not taken into account in previous heritability studies. The relevance of ST-elevation at Jt point (especially in inferior leads) is not evident enough. Our aim was to assess the heritability of ER with ST-elevation in inferior leads among offspring of such patients and patients' follow-up results.

Materials and Methods:

A prospective study of 16 consecutive patients with inferior ST-elevation at Jt ≥0.1 mV, who have arrived to outpatient department most often due to chest pain not associated with coronary stenosis according to multislice computed tomography angiography, started in 2013. Repeated cardiologist evaluation included their 12 children in 2017. Comparisons were made with 16 age- and gender-matched control patients' rest 12-lead electrocardiograms (ECGs) from the outpatient department of year 2018. Impact of ST-elevation's localization and sex on heritability were assessed by odds ratio (OR) with 95% confidence interval (CI).

Results:

There were no significant changes of patients' (all men) health and ECGs during follow-up. Eight (66.7%) of their children were ECG-positive versus 1 (6.2%) control patient,P = 0.001. All siblings (from the same father) of 5 (62.5%) ECG-positive children were ECG-positive. Two of the 5 (male and female) underwent detailed evaluation, including cardiac magnetic resonance, without abnormalities. In cases of only inferior father's ST-elevation, OR, 3.00; 95%CI, 0.24-37.7, and for male children, OR, 7.00; 95%CI, 0.400-23, for presenting with this pattern.

Conclusions:

Constant inferior ST-elevation, even in cases of chest pain, maybe ER, heritable without structural abnormalities. Heritability may be greater for male offspring and in cases of only inferior father's ST-elevation. Longer studies are necessary to confirm that it is benign. We suggest the term “a constant ST-segment elevation (at Jt)” instead of “ST-segment elevation in the absence of chest pain,” with adding that it is possible latent, depending on the heart rate.
A Resolução De Problemas no ensino de estatística no Ensino Fundamental: contribuições da Teoria Antropológica do Didático e a Equivalência de Estímulos

Published: September 2019

O objetivo do trabalho é apresentar a fundamentação teórica utilizada para a criação de problemas no processo ensino e aprendizagem de conteúdos estatísticos do 1° ano do Ensino Fundamental, seguindo os princípios da Teoria Antropológica do Didático – TAD, na organização praxeológica didática e matemática (Estatística) e a Equivalência de Estímulos, para elaborar pequenas unidades de ensino, descrevendo um repertório simples a ser ensinado e progressivamente ir aumentando a complexidade. Na equivalência de estímulos apresentamos uma proposta para a fase de pré-teste considerando que o critério para avançar será de 100%, ou seja, o aluno somente passará para a fase de ensino e teste de discriminações condicionais se acertar a todos os problemas propostos nessa fase. Também utilizaremos os princípios da Teoria Antropológica do Didático – TAD na organização praxeológica didática e matemática (Estatística), constituída de uma sequência de tarefas, que podem ser realizadas utilizando diversas técnicas justificadas pela tecnologia que se utiliza de teorias relacionadas à Estatística como objeto de estudo. Partindo desses pressupostos trazemos a elaboração de subtarefas abordando a necessidade da apreensão da nomenclatura e representação visual para tabela e a leitura de tabelas de colunas simples e coleta e organização de informações sugeridas pela Base Nacional Comum Curricular – BNCC. Acreditamos que utilizar a resolução de problemas como metodologia de ensino constitui-se uma forma interessante de apresentar conceitos básicos da Estatística, pois permitem que estes sejam apresentados de modo atrativo e favorecem a criatividade na elaboração de estratégias de resolução e busca de soluções.
Caminhos trilhados pelo GT12 nas pesquisas em Educação Estatística no Brasil, no período de 2016 a 2018
Authors: Samá Suzi
Published: September 2019

A Educação Estatística é uma área de pesquisa recente no Brasil que tem buscado estudar e compreender os processos de ensino e aprendizagem da Estatística. O presente artigo tem por objetivo investigar as pesquisas em Educação Estatística realizadas pelos membros do Grupo de Trabalho 12 (GT12) da Sociedade Brasileira de Educação Matemática (SBEM), no período de 2016 a 2018. Para tal, realizou-se uma pesquisa exploratória de cunho bibliográfico e documental. Os dados foram analisados por meio da Análise Temática de Conteúdo que possibilitou identificar quatro focos de pesquisa: Currículo e livros didáticos; Formação de professores; Estratégias didáticas; Processos avaliativos e escalas de atitude e autoeficácia. Os resultados evidenciam que as investigações realizadas pelos membros do GT12 abarcam todos os níveis de ensino e apresentam diversidade teórica e metodológica. Considera-se fundamental que os resultados das pesquisas realizadas pelo GT sejam socializadas de forma a suprir as dificuldades tanto dos professores em trabalhar os conceitos estatísticos em sala de aula, quanto dos estudante em compreender estes conceitos e a aplicabilidade da Estatística na própria vida.
Global aridity synthesis for the last 60 000 years

Published: September 2019

Abstract. A compilation of published literature on the dust content in terrestrial and marine sediment cores are synchronised on the basis of pollen data and speleothem growth phases within GICC05 age constrain. Based on that, aridity patterns for ten key areas in the global climate system are reconstructed over the past 60 000 years. These records have different time resolutions and rely on different dating methods, thus of various types of stratigraphy. Nevertheless, all regions show humid conditions during the early MIS3 and early Holocene, but not always of the same timing. Such discrepancies have been interpreted as regional effects while also due to stratigraphical uncertainties. In comparison, the MIS2 interval becomes arid in all northern hemisphere records, but the peak arid conditions of the Last Glacial Maximum (LGM) differ in duration and intensity among regions. In addition, we also make comparisons between the aridity synthesis to modelling results using a Global Climate Model (GCM). Indeed, both lines of evidence show great agreement for the Holocene, LGM and for the late MIS intervals.

Abstract. Since the turn of the 21st Century, image based velocimetry techniques have become an increasingly popular approach for determining open-channel flow in a range of hydrological settings across Europe, and beyond. Simultaneously, a range of large-scale image velocimetry algorithms have been developed, equipped with differing image pre-processing, and analytical capabilities. Yet in operational hydrometry, these techniques are utilised by few competent authorities. Therefore, imagery collected for image velocimetry analysis, along with validation data is required both to enable inter-comparisons between these differing approaches and to test their overall efficacy. Through benchmarking exercises, it will be possible to assess which approaches are best suited for a range of fluvial settings, and to focus future software developments. Here we collate, and describe datasets acquired from six countries across Europe and Asia, consisting of videos that have been subjected to a range of pre-processing, and image velocimetry analysis (Perks et al., 2019, https://doi.org/10.4121/uuid:34764be1-31f9-4626-8b11-705b4f66b95a). Validation data is available for 12 of the 13 case studies presented enabling these data to be used for validation and accuracy assessment.
