Abstract
We present joint observations of the Sun by the Atacama Large Millimeter/submillimeter Array (ALMA) and the Interface Region Imaging Spectrograph (IRIS). Both millimeter/submillimeter-λ continuum emission and ultraviolet (UV) line emission originate from the solar chromosphere and both have the potential to serve as powerful and complementary diagnostics of physical conditions in this enigmatic region of the solar atmosphere. The observations were made of a solar active region on 2015 December 18 as part of the ALMA science verification effort. A map of the Sun’s continuum emission was obtained by ALMA at a wavelength of 1.25 mm (239 GHz). A contemporaneous map was obtained by IRIS in the Mg ii h doublet line at 2803.5 Å. While a clear correlation between the 1.25 mm brightness temperature T

B
and the Mg ii h line radiation temperature T
rad is observed, the slope is <1, perhaps as a result of the fact that these diagnostics are sensitive to different parts of the chromosphere and that the Mg ii h line source function includes a scattering component. There is a significant difference (35%) between the mean T

B
(1.25 mm) and mean T
rad (Mg ii). Partitioning the maps into “sunspot,” “quiet areas,” and “plage regions” we find the relation between the IRIS Mg ii h line T
rad and the ALMA T

B
region-dependent. We suggest this may be the result of regional dependences of the formation heights of the IRIS and ALMA diagnostics and/or the increased degree of coupling between the UV source function and the local gas temperature in the hotter, denser gas in plage regions.
Scientific-theoretical research approach to practical theology in South Africa: A contemporary overview
Authors: Pieterse Hennie J.C. 
Published: August 2017

In this article, I present a critical literature study of the theoretical approach of practical theologians in South Africa to our discipline, in honour of Yolanda Dreyer on her 60th birthday. Some of my colleagues’ approaches at the universities of Stellenbosch, Free State, Pretoria, Unisa and NWU (Potchefstroom campus) are discussed. All of them work with practical theological hermeneutics. The basic hermeneutic approach of Daniël Louw is widened with an integrated approach by Richard R. Osmer in which practical theology as a hermeneutic discipline also includes the empirical aspect which the action theory approach has contributed to the discussion. After discussing Louw’s basic hermeneutic approach, all the other colleagues who basically accepted Osmer’s approach in their publications are discussed. Important and new ground is being broken by contemporary colleagues, including research in public practical theology, without neglecting the focus on Christian congregations, and new work is being done at the grass roots level of African issues in our country.

Abstract. The mixing layer height (MLH) is a measure for the vertical turbulent exchange within the boundary layer, which is one of the controlling factors for the dilution of pollutants emitted near the ground. Based on continuous MLH measurements with a Vaisala CL51 ceilometer and measurements from an air quality network, the relationship between MLH and near-surface pollutant concentrations has been investigated. In this context the uncertainty of the MLH retrievals and the representativeness of ground-based in situ measurements are crucial. We have investigated this topic by using data from the BAERLIN2014 campaign in Berlin, Germany, conducted from June to August 2014. To derive the MLH, three versions of the proprietary software BL-VIEW and a novel approach COBOLT were compared. It was found that the overall agreement is reasonable if mean diurnal cycles are considered. The main advantage of COBOLT is the continuous detection of the MLH with a temporal resolution of 10 min and a lower number of cases when the residual layer is misinterpreted as mixing layer. We have calculated correlations between MLH as derived from the different retrievals and concentrations of pollutants (PM10, O3 and NOx) for different locations in the metropolitan area of Berlin. It was found that the correlations with PM10 are quite different for different sites without showing a clear pattern, whereas the correlation with NOx seems to depend on the vicinity of emission sources in main roads. In the case of ozone as a secondary pollutant, a clear correlation was found. We conclude that the effects of the heterogeneity of the emission sources, chemical processing and mixing during transport exceed the differences due to different MLH retrievals. Moreover, it seems to be unrealistic to find correlations between MLH and near-surface pollutant concentrations representative for a city like Berlin (flat terrain), in particular when traffic emissions are dominant. Nevertheless it is worthwhile to use advanced MLH retrievals for ceilometer data, for example as input to dispersion models and for the validation of chemical transport models.
Borges Reads Machado: A Translation of “A Cartomante” in Revista Multicolor De Los Sábados
Authors: Mendes de Souza Marcelo 
Published: August 2017

Abstract
Comparisons between Machado de Assis and Jorge Luis Borges share one commonality: they all fail to mention any direct relation between the two authors. This article discusses a translation of Machado's “A Cartomante,” published in Revista Multicolor de los Sábados, a literary magazine edited by Borges, as a direct link between them. It proceeds to analyze parallels between Machado's “A Cartomante” and Borges' “Eastman, el proveedor de iniquidades,” both published in the same space, to finally undertake a close reading of the translation. It concludes that both stories are literary metafictional narrative experiences with genre fiction, initially aimed at expanding reading publics of modernizing Latin America. A new light is thrown in the understanding of these two writers; namely Machado is here recast as part of Borges' ever-expanding canon.
The Intrusive “I” in Translations of Italian Librettos
Authors: Edo Miquel 
Published: August 2017

Abstract
The modern aesthetic-linguistic code that governs translations of Italian opera librettos is fundamentally rooted in Romanticism. This code clashes to some extent with the code governing the source texts, where Romantic guiding principles fuse over a solid Petrarchan and Arcadian substratum indebted to the Dolce Stil Novo poetry of the late Middle Ages. This substratum is eroded in many translations, principally through a reinforcement of the first person (“I”) at the expense of things (in general) and feelings and vital organs (in particular), which, in the original libretto, are endowed with the capacity to act as independent agents. Accompanying this different epistemic approach to reality and the individual are noteworthy discrepancies in the use of rhetorical devices, marked by: (a) a lesser propensity in translations for circumlocution, personification, and synecdoche; (b) a higher degree of flexibility in Italian in the use of ellipsis; and (c) variatio in original librettos in contrast to uniformity and parallelism in translations.
To Punish First and Reward Second: Values Determine How Reward and Punishment Affect Risk-Taking Behavior
Authors: Athota Vidya S. , O’Connor Peter J. , Roberts Richard D. 
Published: August 2017

Abstract
The current study investigated whether manipulating participants’ pre-exposure to reward and punishment affects the extent to which sensation seeking and values predict risk-taking behavior. Participants (n = 195) were randomly allocated to one of two conditions, defined by the order at which they were rewarded or punished for risk-taking behavior. Risk-taking behavior was measured in both conditions using the Balloon Analogue Risk Test, but it was set up such that participants in Group 1 were rewarded for risk-taking behavior before being punished, whereas participants in Group 2 were punished for risk-taking behavior before being rewarded. Participants also completed questionnaires designed to measure sensation seeking and the values of stimulation (the need for novelty and excitement) and hedonism (the need for sensuous pleasure). It was found that stimulation predicted risk-taking behavior in the reward-then-punishment condition, whereas hedonism predicted risk-taking behavior in the punishment-then-reward condition. Sensation seeking was found to be an indirect predictor of risk-taking behavior in both conditions. It is tentatively concluded that the extent to which participants’ risk-taking behavior is guided by their values (hedonism, stimulation) largely depends on their prior exposure to the order of contingent reward and punishment.
Lactation Cessation and the Realities of Martyrdom in The Passion of Saint Perpetua
Authors: Dova Stamatia 
Published: August 2017

Abstract
This article examines the significance of breastfeeding in the self-definition of Perpetua, author and protagonist of the Passio Perpetuae et Felicitatis. Through close readings of all relevant passages, this discussion intends to demonstrate that Perpetua’s desire to continue nursing her son in prison as well as her eventual resignation to lactation cessation exemplify her struggle to balance her roles as mother and martyr. By illustrating how motherhood foreshadows martyrdom in the Passio, this analysis also highlights the narrator’s thorough knowledge of the realities of breastfeeding as an argument that further supports female authorship.

Published: August 2017

ResumenEl objetivo de este estudio fue determinar si había diferencias entre un grupo de futbolistas que han estado lesionados la temporada anterior y uno de futbolistas que no han estado lesionados en los niveles de apoyo social percibido por parte de los jugadores. La muestra estuvo formada por 219 jugadores sénior de fútbol (80.1 %) y fútbol sala (19.9 %) federados (de categorías primera, segunda, autonómica, preferente y categorías inferiores) a nivel regional. De ellos, 138 futbolistas formaron el grupo de aquellos que no sufrieron ninguna lesión deportiva durante la temporada anterior y 81 que sufrieron una o más lesiones. Las variables de estudio fueron el apoyo social percibido y las lesiones deportivas, evaluadas por la Escala Multidimensional de Apoyo Social Percibido de Landeta y Calvete (2002) y un instrumento ad hoc, respectivamente. Los resultados muestran que el grupo de futbolistas no lesionados, respecto al grupo de futbolistas lesionados, poseía niveles más altos de apoyo social en los tres ámbitos de éste (apoyo de los amigos M = 24.05 frente a M = 23.77; apoyo de la familia M = 24.71 frente a M = 24.19; y apoyo de otras personas relevantes M = 24.74 frente a M = 23.71), aunque dichas diferencias no fueron estadísticamente significativas (p = .708; p = .443; p = .143). No se puede afirmar que la provisión de apoyo social a los jugadores de fútbol sirva para prevenir las lesiones deportivas, aunque sí existen diferencias entre el grupo de lesionados y el grupo de no lesionados, pero éstas no han sido significativas. AbstractThe aim of this study was to determine if there were dif­ferences between a group of players who have been in­jured the previous season and one of players who have not been injured in the levels of social support perceived by the players. The sample consisted of 219 senior foot­ball players (80.1 %) and federated football (19.9 %) at the regional level. Of these, 138 football players formed the group of those who did not suffer any sport injury during the previous season and 81 who suffered one or more injuries. The study variables were perceived social support and sports injuries, assessed by the Multidimen­sional Scale of Social Perceived Support (Landeta y Cal­vete, 2002) and an ad hoc instrument, respectively. The results show that the group of players non-injured play­ers, compared to the group of injured players, had higher levels of social support in three areas of this (friends support M = 24.05 vs. M = 23.77; family support M = 24.71 vs. M = 24.19; and support from other relevant people M = 24.74 vs. M = 23.71), although these differences were not statistically significant (p = .708; p = .443; p = .143). We cannot say that the provision of social support for soccer players serve to prevent sports injuries, although there are differences between the group of injured and unin­jured group, but these have not been significant.
Metaphor, Paradigm, and Education
Authors: Ivie Stanley D. 
Published: August 2017

Metaphor is a critical tool for thought. Lying at the heart of every systematic body of knowledge are three root metaphors — mechanism, organism, and mind. Historically, schools of philosophy — realism, naturalism, and idealism — have grown up around these metaphors. The root metaphors and their corresponding philosophies provide the paradigms underlying different exemplars of education. To illustrate how metaphors, paradigms, and exemplars all shape educational thought, the works of three educators — Hunter, Piaget, and Bruner — have been selected.
Désengagement professionnel des enseignants canadiens : de la vocation à la désillusion. Une analyse à partir d’une modélisation par équations structurelles
Authors: Kamanzi Pierre Canisius , Barroso da Costa Carla , Ndinga Pascal 
Published: August 2017

Cet article vise à cerner les facteurs en lien avec le désengagement professionnel observé auprès des enseignants canadiens. Une analyse des données tirées d’une enquête pancanadienne auprès des enseignants (N = 3 221) révèle que ce désengagement est significativement associé aux facteurs suivants : les expériences émotionnelles négatives dues aux relations difficiles avec les élèves, la perception des changements de politiques éducatives, la satisfaction vis-à-vis des conditions de travail et le sentiment de compétence. Des quatre variables étudiées, les expériences émotionnelles représentent le facteur qui explique davantage le désengagement professionnel. Des analyses révèlent qu’à quelques différences près, la situation est similaire dans les quatre provinces étudiées : Alberta, Colombie-Britannique, Ontario et Québec.
Le parcours de formation axée sur l’emploi : la parole aux jeunes
Authors: Rousseau Nadia , Bergeron Léna 
Published: August 2017

Le Parcours de formation axée sur l’emploi (PFAE) constitue une offre de formation qualifiante principalement destinée aux élèves ayant des défis scolaires variés et importants. En d’autres mots, il s’agit là d’une diversification des parcours menant à l’obtention d’un certificat de formation qualifiante reconnu par le Ministère de l’Éducation et de l’Enseignement supérieur (MEES). Cela dit, que pensent les jeunes, souvent inscrits par obligation, de cette formation ? Qu’ont-ils à nous apprendre sur la cohérence entre ce qu’ils y vivent et sur les intentions premières de ce programme ? C’est à travers une recherche qualitative réalisée auprès de 149 élèves provenant de six écoles secondaires que nous avons cherché à comprendre comment se vit cette voie de formation.
Au-delà des déterminismes biologique et classiste dans l’explication des inégalités scolaires
Authors: Goyer Renaud , Borri-Anadon Corina 
Published: August 2017

Cette critique appartient à une série de trois articles de la section Forum sur le livre de Barnes (2016), Are They Rich Because They’re Smart? Elle analyse les arguments dont Barnes se sert pour déconstruire le point de vue défendu par Herrstein et Murray (1994) dans The Bell Curve. Pour Barnes, le discours de Herrstein et Murray remplit une fonction politique, et non scientifique : il sert à justifier, avec des arguments biologiques faux, les inégalités économiques dont la soi-disant méritocratie profite, alors que l’explication des inégalités socioéconomiques et culturelles est sociopolitique. La réponse de Barnes, centrée sur la lutte des classes sociales, minimise toutefois le rôle des pratiques et des interactions des agents dans l’analyse des rapports sociaux inégalitaires.
Time series prediction using artificial neural networks
Authors: Pérez-Chavarría MA , Hidalgo-Silva HH , Ocampo-Torres FJ 
Published: August 2017

In this work, artificial neural network (ANN) algorithms were used to predict time series of the oceanographic variables Southern Oscilation Index (SOI) and sea surface temperature anomaly (SSTA). The finite impulse response neural network (FIRNN) was applied to data obtained from the NOAA. In order to determine the most efficient FIRNN architecture, several experiments were made varying different parameters. The best predictions were obtained for a network with one input neuron and 10th-order filters in the input layer, two 8-neuron 5th-order filter hidden layers and one output neuron. All the networks were trained with the temporal backpropagation learning algorithm, using the sigmoid transfer function at the hidden layers and a linear output. The learning rate was 0.001. In most experiments a normalized mean square error of 0.4 ± 0.1 and a correlation coefficient between the original and the predicted series greater than 0.8 were found. From a comparison with other SSTA prediction methods, the results obtained with the neural network were the best ones for the short term forecasting case.
Spatiotemporal changes of seismic attenuation caused by injected CO2 at the Frio‐II pilot site, Dayton, TX, USA
Authors: Zhu Tieyuan , Ajo‐Franklin Jonathan B. , Daley Thomas M. 
Published: August 2017

AbstractA continuous active source seismic monitoring data set was collected with crosswell geometry during CO2 injection at the Frio‐II brine pilot, near Liberty, TX. Previous studies have shown that spatiotemporal changes in the P wave first arrival time reveal the movement of the injected CO2 plume in the storage zone. To further constrain the CO2 saturation, particularly at higher saturation levels, we investigate spatial‐temporal changes in the seismic attenuation of the first arrivals. The attenuation changes over the injection period are estimated by the amount of the centroid frequency shift computed by local time‐frequency analysis. We observe that (1) at receivers above the injection zone seismic attenuation does not change in a physical trend; (2) at receivers in the injection zone attenuation sharply increases following injection and peaks at specific points varying with distributed receivers, which is consistent with observations from time delays of first arrivals; then, (3) attenuation decreases over the injection time. The attenuation change exhibits a bell‐shaped pattern during CO2 injection. Under Frio‐II field reservoir conditions, White's patchy saturation model can quantitatively explain both the P wave velocity and attenuation response observed. We have combined the velocity and attenuation change data in a crossplot format that is useful for model‐data comparison and determining patch size. Our analysis suggests that spatial‐temporal attenuation change is not only an indicator of the movement and saturation of CO2 plumes, even at large saturations, but also can quantitatively constrain CO2 plume saturation when used jointly with seismic velocity.
Sensitivity analysis of multiport S‐parameter measurements due to nonideal TRL calibration standards
Authors: Wang M. , Zhao Y. J. , Jin Y. M. , Zhou Y. G. 
Published: August 2017

AbstractIn this paper, a detailed analysis of n‐port vector network analyzer measurement uncertainties due to nonideal standards for multiport through‐reflect‐line calibration is presented. By using the concept of general node equations, the error correction equation is simplified by the matrix operation; thus, a generalized formula for the deviations of the measured S parameters with respect to the error terms is derived, which can be implemented in further analysis of multiport measurement uncertainties applying arbitrary calibration method based on 4n‐term error model. The final expressions for the sensitivity coefficients of S parameters with simple and clear form provide a deeper understanding of error propagation mechanisms.
Implementation of respiratory‐gated VMAT on a Versa HD linear accelerator
Authors: Snyder Jeffrey E. , Flynn Ryan T. , Hyer Daniel E. 
Published: August 2017

AbstractThe accurate delivery of respiratory‐gated volumetric modulated arc therapy (VMAT) treatment plans presents a challenge since the gantry rotation and collimator leaves must be repeatedly stopped and set into motion during each breathing cycle. In this study, we present the commissioning process for an Anzai gating system (AZ‐733VI) on an Elekta Versa HD linear accelerator and make recommendations for successful clinical implementation. The commissioning tests include central axis dose consistency, profile consistency, gating beam‐on/off delay, and comparison of gated versus nongated gamma pass rates for patient‐specific quality assurance using four clinically commissioned photon energies: 6 MV, 6 FFF, 10 MV, and 10 FFF. The central axis dose constancy between gated and nongated deliveries was within 0.6% for all energies and the analysis of open field profiles for gated and nongated deliveries showed an agreement of 97.8% or greater when evaluated with a percent difference criteria of 1%. The measurement of the beam‐on/off delay was done by evaluating images of a moving ball‐bearing phantom triggered by the gating system and average beam‐on delays of 0.22–0.29 s were observed. No measurable beam‐off delay was present. Measurements of gated VMAT dose distributions resulted in decrements as high as 9% in the gamma passing rate as compared to nongated deliveries when evaluated against the planned dose distribution at 3%/3 mm. By decreasing the dose rate, which decreases the gantry speed during gated delivery, the gamma passing rates of gated and nongated treatments can be made equivalent. We present an empirically derived formula to limit the maximum dose rate during VMAT deliveries and show that by implementing a reduced dose rate, a gamma passing rate of greater than 95% (3%/3 mm) was obtained for all plan measurements.
