Faculty Perspectives of Technology-Enhanced Course Redesign
Authors: Dunston Yolanda L. , Patterson Gerrelyn C. , Bull Prince Hycy
Published: November 2015

This chapter will discuss how one team of faculty members used technology enhancements to transform the delivery of their own existing courses into new and improved courses which could be delivered consistently over time and in a variety of delivery modes (i.e., face-to-face, online, or hybrid), while maintaining course rigor. Previously, the selected courses had been redesigned for online delivery, but with limited technology enhancements. As faculty members progressed through the steps of the redesign process, many opportunities for reflection and introspection emerged. This chapter provides their perceptions of features of online learning, including course design, course delivery, assessment of learning and teaching, and student and instructor roles. The chapter concludes with implications for working with faculty from a variety of levels of willingness and technological proficiency for developing effective online learning environments.

Authors: Ossiannilsson Ebba
Published: November 2015

The UNESCO Post-2015 Development Agenda proposes equitable quality education and lifelong learning for all as its overarching goals for education. A holistic quality approach is espoused to encourage lifelong learning and thereby build inclusive, sustainable, and prosperous societies. Their quality goals are particularly ambitious given that the practical recommendations for inclusive education necessitate ubiquity and are disruptive of existing processes. Higher education is facing widespread and serious challenges in terms of helping individuals develop and acquire the ability to advance and sustain their own learning. Proactive and innovative strategies are required to fully embrace the open learning culture in a manner that aligns with the global driving forces for the development of the individual, society, and the world in general. This chapter examines shaping the future of education related to UNESCO Post-2015, especially its interrelatedness with adhering to quality standards in education for all.

The abortion-prone mating combination CBA/J × DBA/2 has been recognized as a model of preeclampsia, and complement activation has been implicated in the high rate of pregnancy loss observed in CBA/J mice. We have analyzed the implantation sites collected from DBA/2-mated CBA/J mice for the deposition of the complement recognition molecules using CBA/J mated with BALB/c mice as a control group. MBL-A was observed in the implantation sites of CBA/J × DBA/2 combination in the absence of MBL-C and was undetectable in BALB/c-mated CBA/J mice. Conversely, C1q was present in both mating combinations. Searching for other complement components localized at the implantation sites of CBA/J × DBA/2, we found C4 and C3, but we failed to reveal C1r. These data suggest that complement is activated through the lectin pathway and proceeds to completion of the activation sequence as revealed by C9 deposition. MBL-A was detected as early as 3.5 d of pregnancy, and MBL-A deficiency prevented pregnancy loss in the abortion-prone mating combination. The contribution of the terminal complex to miscarriage was supported by the finding that pregnancy failure was largely inhibited by the administration of neutralizing Ab to C5. Treatment of DBA/2-mated CBA/J mice with Polyman2 that binds to MBL-A with high affinity proved to be highly effective in controlling the activation of the lectin pathway and in preventing fetal loss.

Treatment of autoimmune diseases is still largely based on the use of systemically acting immunosuppressive drugs, which invariably cause severe side effects. Calcium/calmodulin-dependent protein kinase IV is involved in the suppression of IL-2 and the production of IL-17. Its pharmacologic or genetic inhibition limits autoimmune disease in mice. In this study, we demonstrate that KN93, a small-molecule inhibitor of calcium/calmodulin-dependent protein kinase IV, targeted to CD4+ T cells via a nanolipogel delivery system, markedly reduced experimental autoimmune encephalomyelitis and was 10-fold more potent than the free systemically delivered drug in the lupus mouse models. The targeted delivery of KN93 did not deplete T cells but effectively blocked Th17 cell differentiation and expansion as measured in the spinal cords and kidneys of mice developing experimental autoimmune encephalomyelitis or lupus, respectively. These results highlight the promise of cell-targeted inhibition of molecules involved in the pathogenesis of autoimmunity as a means of advancing the treatment of autoimmune diseases.
Fetal echopsy (ultrasonographic autopsy) of an acardius myelancephalus and its correlation with antenatal ultrasonographic findings
Authors: Karippaliyil Balakumar , Karippaliyil Milind , Karippaliyil Misha
Published: November 2015

Aberrant transplacental arteriovenous shunts between the placental and cord vessels of monozygotic monoamniotic twins or triplets result in the formation of an acardius. The prenatal diagnosis of this condition has been reported occasionally in the literature. A subtype categorized as acardius myelancephalus was diagnosed at 32 weeks of gestation by ultrasonography (USG). The pregnancy was aborted because of poor prognostic predictors and the acardius was subjected to ultrasonographic autopsy (fetal echopsy). The antenatal USG features were correlated with echopsy findings for confirmation of the antenatal findings and for a better visual perception of the prenatal diagnostic features. The echopsy revealed more precise details. Fetal echopsy avoids the medicolegal problems concerned with parental consent for classical invasive fetal autopsy.
Qualitative and quantitative diffusion-weighted imaging of the breast at 3T - A useful adjunct to contrast-enhanced MRI in characterization of breast lesions
Authors: Bansal Richa , Shah Viral , Aggarwal Bharat
Published: November 2015

Objective: To distinguish between benign and malignant breast lesions on the basis of their signal intensity on diffusion-weighted imaging and their apparent diffusion coefficient (ADC) values at 3 T MRI, along with histopathological correlation. Materials and Methods: A retrospective analysis of 500 patients who underwent 3 T MRI between August 2011 and May 2013 was done. Of these, 226 patients with 232 lesions that were proved by histopathology were included in the study. ADC values were calculated at b values of 0, 1000, and 1500 s/mm2 after identification on contrast-enhanced images and appropriate ROI(Region of interest) placement. ADC value and histopathology correlation was analyzed. Results: Out of 232 lesions, 168 lesions were histologically malignant and 64 were histologically benign. With an ADC cut-off value of 1.1 ×10−3 mm2/s for malignant lesions, a sensitivity of 92.80% and specificity of 80.23% was obtained. Out of 12/232 false-negative lesions, 6 were mucinous carcinoma in which a high ADC value of 1.8-1.9 ×10−3 mm2/s was obtained. Purely DCIS (Ductal carcinoma in situ) lesions presenting as non-mass-like enhancement had a high ADC value of 1.2-1.5 ×10−3 mm2/s, thereby reducing specificity. Conclusion: Diffusion-weighted Imaging and quantitative assessment by ADC values may act as an effective parameter in increasing the diagnostic accuracy and specificity of contrast-enhanced breast MRI in characterization of breast lesions.

Authors: Satija Bhawna , Kumar Sanyal , Wadhwa Leena , Gupta Taru , Kohli Supreethi , Chandoke Rajkumar , Gupta Pratibha
Published: November 2015

Context: Placenta accreta is the abnormal adherence of the placenta to the uterine wall and the most common cause for emergency postpartum hysterectomy. Accurate prenatal diagnosis of affected pregnancies allows optimal obstetric management. Aims: To summarize our experience in the antenatal diagnosis of placenta accreta on imaging in a tertiary care setup. To compare the accuracy of ultrasound (USG) with color Doppler (CDUS) and magnetic resonance imaging (MRI) in prenatal diagnosis of placenta accreta. Settings and Design: Prospective study in a tertiary care setup. Materials and Methods: A prospective study was conducted on pregnant females with high clinical risk of placenta accreta. Antenatal diagnosis was established based on CDUS and MRI. The imaging findings were compared with final diagnosis at the time of delivery and/or pathologic examination. Statistical Analysis Used: The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated for both CDUS and MRI. The sensitivity and specificity values of USG and MRI were compared by the McNemar test. Results: Thirty patients at risk of placenta accreta underwent both CDUS and MRI. Eight cases of placenta accreta were identified (3 vera, 4 increta, and 1 percreta). All patients had history of previous cesarean section. Placenta previa was present in seven out of eight patients. USG correctly identified the presence of placenta accreta in seven out of eight patients (87.5% sensitivity) and the absence of placenta accreta in 19 out of 22 patients (86.4% specificity). MRI correctly identified the presence of placenta accreta in 6 out of 8 patients (75.0% sensitivity) and absence of placenta accreta in 17 out of 22 patients (77.3% specificity). There were no statistical differences in sensitivity (P = 1.00) and specificity (P = 0.687) between USG and MRI. Conclusions: Both USG and MRI have fairly good sensitivity for prenatal diagnosis of placenta accreta; however, specificity does not appear to be as good as reported in other studies. Both modalities have complimentary role and in cases of inconclusive findings with one imaging modality, the other modality may be useful for obtaining the diagnosis. CDUS remains the first primary modality for antenatal diagnosis of placenta accreta, with MRI reserved for cases where USG is inconclusive.

Abstract. Lidar observations of smoke aerosols have been analysed from six flights of the Facility for Airborne Atmospheric Measurements BAe-146 research aircraft over Brazil during the biomass burning season (September 2012). A large aerosol depth (AOD) was observed, typically ranging 0.4–0.9, along with a typical aerosol extinction coefficient of 100–400 Mm−1. The data highlight the persistent and widespread nature of the Amazonian haze, that had a consistent vertical structure, observed over a large distance (~ 2200 km) during a period of 14 days. Aerosols were found near the surface; but the larger aerosol load was typically found in elevated layers that extended from 1–1.5 to 4–6 km. The measurements have been compared to model predictions with the Met Office Unified Model (MetUM) and the ECMWF-MACC model. The MetUM generally reproduced the vertical structure of the Amazonian haze observed with the lidar. The ECMWF-MACC model was also able to reproduce the general features of smoke plumes albeit with a small overestimation of the AOD. The models did not always capture localized features such as (i) smoke plumes originating from individual fires, and (ii) aerosols in the vicinity of clouds. In both these circumstances, peak extinction coefficients of the order of 1000–1500 Mm−1 and AODs as large as 1–1.8 were encountered, but these features were either underestimated or not captured in the model predictions. Smoke injection heights derived from the Global Fire Assimilation System (GFAS) for the region are compatible with the general height of the aerosol layers.
A new source of methyl glyoxal in the aqueous phase
Authors: Rodigast M. , Mutzel A. , Schindelka J. , Herrmann H.
Published: November 2015

Abstract. Carbonyl compounds are ubiquitous in atmospheric multiphase system participating in gas, particle, and aqueous-phase chemistry. One important compound is methyl ethyl ketone (MEK), as it is detected in significant amounts in the gas phase as well as in cloud water, ice, and rain. Consequently, it can be expected that MEK influences the liquid phase chemistry. Therefore, the oxidation of MEK and the formation of corresponding oxidation products were investigated in the aqueous phase. Several oxidation products were identified from the oxidation with OH radicals, including 2,3-butanedione, hydroxyacetone, and methyl glyoxal. The molar yields were 29.5 % for 2,3-butanedione, 3.0 % for hydroxyacetone, and 9.5 % for methyl glyoxal. Since methyl glyoxal is often related to the formation of organics in the aqueous phase, MEK should be considered for the formation of aqueous secondary organic aerosol (aqSOA). Based on the experimentally obtained data, a reaction mechanism for the formation of methyl glyoxal has been developed and evaluated with a model study. Besides known rate constants, the model contains measured photolysis rate constants for MEK (kp = 5 × 10−5 s−1), 2,3-butanedione (kp = 9 × 10−6 s−1), methyl glyoxal (kp = 3 × 10−5 s−1), and hydroxyacetone (kp = 2 × 10−5 s−1). From the model predictions, a branching ratio of 60/40 for primary/secondary H-atom abstraction at the MEK skeleton was found. This branching ratio reproduces the experiment results very well, especially the methyl glyoxal formation, which showed excellent agreement. Overall, this study demonstrates MEK as a methyl glyoxal precursor compound for the first time.
Multi-year high-frequency physical and environmental observations at the Guadiana Estuary
Authors: Garel E. , Ferreira Ó.
Published: November 2015

Abstract. High-frequency data collected continuously over a multi-year time frame are required for investigating the various agents that drive ecological and hydrodynamic processes in estuaries. Here, we present water quality and current in situ observations from a fixed monitoring station operating from 2008 to 2014 in the lower Guadiana Estuary, southern Portugal (37°11.30' N, 7°24.67' W). The data were recorded by a multi-parametric probe providing hourly records (temperature, salinity, chlorophyll, dissolved oxygen, turbidity, and pH) at a water depth of ~ 1 m, and by a bottom-mounted acoustic Doppler current profiler measuring the pressure, near-bottom temperature, and flow velocity through the water column every 15 min. The time series data, in particular the probe ones, present substantial gaps arising from equipment failure and maintenance, which are ineluctable with this type of observation in harsh environments. However, prolonged (months-long) periods of multi-parametric observations during contrasted external forcing conditions are available. The raw data are reported together with flags indicating the quality status of each record. River discharge data from two hydrographic stations located near the estuary head are also provided to support data analysis and interpretation. The data set is publicly available in machine-readable format at PANGAEA (doi:10.1594/PANGAEA.845750).
GO2OGS 1.0: a versatile workflow to integrate complex geological information with fault data into numerical simulation models

Published: November 2015

Abstract. We offer a versatile workflow to convert geological models built with the ParadigmTM GOCAD© (Geological Object Computer Aided Design) software into the open-source VTU (Visualization Toolkit unstructured grid) format for usage in numerical simulation models. Tackling relevant scientific questions or engineering tasks often involves multidisciplinary approaches. Conversion workflows are needed as a way of communication between the diverse tools of the various disciplines. Our approach offers an open-source, platform-independent, robust, and comprehensible method that is potentially useful for a multitude of environmental studies. With two application examples in the Thuringian Syncline, we show how a heterogeneous geological GOCAD model including multiple layers and faults can be used for numerical groundwater flow modeling, in our case employing the OpenGeoSys open-source numerical toolbox for groundwater flow simulations. The presented workflow offers the chance to incorporate increasingly detailed data, utilizing the growing availability of computational power to simulate numerical models.
Nonlinear effects of locally heterogeneous hydraulic conductivity fields on regional stream–aquifer exchanges
Authors: Zhu J. , Winter C. L. , Wang Z.
Published: November 2015

Abstract. Computational experiments are performed to evaluate the effects of locally heterogeneous conductivity fields on regional exchanges of water between stream and aquifer systems in the Middle Heihe River basin (MHRB) of northwestern China. The effects are found to be nonlinear in the sense that simulated discharges from aquifers to streams are systematically lower than discharges produced by a base model parameterized with relatively coarse effective conductivity. A similar, but weaker, effect is observed for stream leakage. The study is organized around three hypotheses: (H1) small-scale spatial variations of conductivity significantly affect regional exchanges of water between streams and aquifers in river basins, (H2) aggregating small-scale heterogeneities into regional effective parameters systematically biases estimates of stream–aquifer exchanges, and (H3) the biases result from slow paths in groundwater flow that emerge due to small-scale heterogeneities. The hypotheses are evaluated by comparing stream–aquifer fluxes produced by the base model to fluxes simulated using realizations of the MHRB characterized by local (grid-scale) heterogeneity. Levels of local heterogeneity are manipulated as control variables by adjusting coefficients of variation. All models are implemented using the MODFLOW (Modular Three-dimensional Finite-difference Groundwater Flow Model) simulation environment, and the PEST (parameter estimation) tool is used to calibrate effective conductivities defined over 16 zones within the MHRB. The effective parameters are also used as expected values to develop lognormally distributed conductivity (K) fields on local grid scales. Stream–aquifer exchanges are simulated with K fields at both scales and then compared. Results show that the effects of small-scale heterogeneities significantly influence exchanges with simulations based on local-scale heterogeneities always producing discharges that are less than those produced by the base model. Although aquifer heterogeneities are uncorrelated at local scales, they appear to induce coherent slow paths in groundwater fluxes that in turn reduce aquifer–stream exchanges. Since surface water–groundwater exchanges are critical hydrologic processes in basin-scale water budgets, these results also have implications for water resources management.

Published: November 2015

Abstract. The present research is aimed at a critical analysis of a method presently used for evaluating failure hazard in linear objects in mining areas. A fuzzy model of failure hazard of a linear object was created on the basis of the experience gathered so far. The rules of Mamdani fuzzy model have been used in the analyses. Finally the scaled model was integrated with a Geographic Information System (GIS), which was used to evaluate failure hazard in a water pipeline in a mining area.
Investigation of alternative mechanisms of aquifer-system compaction and land subsidence in Shanghai
Authors: Yuan Y. , Xu Y.-S. , Shen S.-L. , Zhang N.
Published: November 2015

Abstract. Alternative subsidence mechanisms related to groundwater extration and surface loading of built infrastructure in Shanghai have been evaluated to explain continued subsidence despite the controlled reduction of groundwater extraction. The traditional theory of aquifer-system compaction embodied in the aquitard drainage model cannot fully explain this phenomenon. Two possible alternative mechanisms were studied previously: (i) surface loading attributed to urban construction; (ii) creep occuring in sandy deposits of aquifers. These mechanisms could not fully explain the observed subsidence. Two additional alternative mechanistic models are proposed that involve principles of load transfer considering the temporally and spatially redistributed stresses associated with groundwater extraction: (i) the Cosserat continuum mechanism, considering shear force on the permeable coarse-grained matrial in the aquifer due to hydraulic gradients in the aquifer; and (ii) internal erosion of fine-grained (clay and silt) particles within the aquifer. Initial results based on simulations incorporating Cosserat mechanics look promising.

Authors: González-Hernández M. , Carreón-Freyre D. , Gutierrez-Calderon R. , Cerca M. , Flores-Garcia W.
Published: November 2015

Abstract. Geological and structural conditions in the Basin of Mexico coupled with natural and anthropogenic factors, such as groundwater exploitation, provokes land subsidence and differential deformation. The study area is located in to the north of Iztapalapa, a municipality within Mexico City, in a site called "El Eden" with irregular topography. Where volcanic sequences overlie the lacustrine deposits of clays and silts and show displacements by the action of gravity. The displacement zone was delimited at the top of the slope by the formation of circular tensile fractures with stair -shaped geometries. At the base of the slope, compressive processes damaged housing, sidewalks and inclined light poles and trees. A NW-SE system of fractures was identified in which displacement velocities vary from a few millimeters to several centimeters per year. Which affects urban facilities. In this work a conceptual model of deformation is presented that integrates the geological and mechanical factors leading to landslide and land subsidence. A geophysical survey leads to evidence of how land subsidence processes increase the sliding slope.

Abstract. The Tertiary detritic aquifer of Madrid (TDAM), with an average thickness of 1500 m and a heterogeneous, anisotropic structure, supplies water to Madrid, the most populated city of Spain (3.2 million inhabitants in the metropolitan area). Besides its complex structure, a previous work focused in the north-northwest of Madrid city showed that the aquifer behaves quasi elastically trough extraction/recovery cycles and ground uplifting during recovery periods compensates most of the ground subsidence measured during previous extraction periods (Ezquerro et al., 2014). Therefore, the relationship between ground deformation and groundwater level through time can be simulated using simple elastic models. In this work, we model the temporal evolution of the piezometric level in 19 wells of the TDAM in the period 1997–2010. Using InSAR and piezometric time series spanning the studied period, we first estimate the elastic storage coefficient (Ske) for every well. Both, the Ske of each well and the average Ske of all wells, are used to predict hydraulic heads at the different well locations during the study period and compared against the measured hydraulic heads, leading to very similar errors when using the Ske of each well and the average Ske of all wells: 14 and 16 % on average respectively. This result suggests that an average Ske can be used to estimate piezometric level variations in all the points where ground deformation has been measured by InSAR, thus allowing production of piezometric level maps for the different extraction/recovery cycles in the TDAM.
Land subsidence caused by a single water extraction well and rapid water infiltration
Authors: Martinez-Noguez I. , Hinkelmann R.
Published: November 2015

Abstract. Nowadays several parts of the world suffer from land subsidence. This setting of the earth surface occurs due to different factors such as earth quakes, mining activities, and gas, oil and water withdrawal. This research presents a numerical study of the influence of land subsidence caused by a single water extraction well and rapid water infiltration into structural soil discontinuities. The numerical simulation of the infiltration was based on a two-phase flow-model for porous media, and for the deformation a Mohr–Coulomb model was used. A two-layered system with a fault zone is presented. First a single water extraction well is simulated producing a cone-shaped (conical) water level depletion, which can cause land subsidence. Land Subsidence can be further increased if a hydrological barrier as a result of a discontinuity, exists. After water extraction a water column is applied on the top boundary for one hours in order to represent a strong storm which produces rapid water infiltration through the discontinuity as well as soil deformation. Both events are analysed and compared in order to characterize deformation of both elements and to get a better understanding of the land subsidence and new fracture formations.
PSI-based methodology to land subsidence mechanism recognition

Published: November 2015

Abstract. A methodology based on Persistent Scatterer Interferometry (PSI) is proposed in order to disentangle the contribution of different processes that act at different spatio-temporal scales in land subsidence (i.e. vadose zone processes as swelling/shrinkage of clay soils, soil consolidation and fluid extraction). The methodology was applied in different Italian geological contexts characterized by natural and anthropic processes (i.e. a Prealpine valley and the Po Plain in northern Italy).

Published: November 2015

Abstract. Shanghai city has been suffering land subsidence caused by overly exploitation of ground water since 1921, which is a serious problem for this coastal city with altitude of 2.2–4.8 m above mean sea level. The largest cumulative land subsidence amounted to 2.6 m in the downtown area. Measures to decrease the ground water exploitation, change the pumping aquifers, and increase aquifer artificial recharge have been used to mitigate land subsidence since 1961. It is necessary to develop a proper numerical model to simulate and predict land subsidence. In this study, a decoupled three-dimensional (3-D) finite element land subsidence model including a 3-D ground water flow model and a 3-D geo-mechanical model was developed to simulate the 3-D deformation of the aquifer systems in the center area of Shanghai. The area of downtown Shanghai is 660 km2, with 10 million inhabitants, dense high buildings, and 11 metro lines. The simulation spans the period from 1979 to 1995. Two different assumptions have been tested on the side boundary, i.e., precluding the three components of the displacement, or assuming a free-displacement condition. The distribution of calculated land subsidence and horizontal displacements in different aquifers was analyzed. The computed vertical displacement fitted well with the available observations. It has been verified that the two different assumptions on the lateral boundaries in the geo-mechanical model caused different results just limited on nodes close to boundary. The developed 3-D land subsidence model is reasonable and can be used to simulate and predict 3-D movement of aquifer systems in the center area of Shanghai, which could provide scientific support to local government in controlling land subsidence and differential movements of the land surface.

Abstract. Multi-sensor advanced DInSAR analyses have been performed and compared with two GPS station measurements, in order to evaluate the land subsidence evolution in a 20-year period, in the Alto Guadalentín Basin where the highest rate of man-induced subsidence (> 10 cm yr−1) of Europe had been detected. The control mechanisms have been examined comparing the advanced DInSAR data with conditioning and triggering factors (i.e. isobaths of Plio-Quaternary deposits, soft soil thickness and piezometric level).
Performance of pile foundation for the civil infrastructure of high speed rail in severe ground subsidence area
Authors: Yang H. W.
Published: November 2015

Abstract. In this study, the performance of pile foundation is assessed for the 30 km long viaduct bridge structure seating in the ground subsidence area in the central part of Taiwan. The focus of this paper is placed on the settlement behaviour of a continuous 3-span R. C. viaduct bridge supported on piles adjacent to highway embankment. Monitoring data accumulated over the last 12 years indicate that the observed pace of the settlement of the viaduct structure in other sections matches that of the ground. However, the bridge piers adjacent to the embankment have been suffering an additional approximately 1 cm settlement every year since the completion of the embankment construction. It was believed that the piers may suffer from enormous negative skin friction owing to the surcharge from the embankment and groundwater depression. This paper first summarizes the settlement analysis results to quantify the settlement of pile due to regional ground subsidence and the combined effects from ground water fluctuation and embankment surcharge loading. Accordingly, a loading path on P'-q stress space is formulated to illustrate the loading variation subject to the combined loading effects that can explain why the combined effect becoming significant on settlement control for civil infrastructure in ground subsidence area.
Groundwater management based on monitoring of land subsidence and groundwater levels in the Kanto Groundwater Basin, Central Japan
Authors: Furuno K. , Kagawa A. , Kazaoka O. , Kusuda T. , Nirei H.
Published: November 2015

Abstract. Over 40 million people live on and exploit the groundwater resources of the Kanto Plain. The Plain encompasses metropolitan Tokyo and much of Chiba Prefecture. Useable groundwater extends to the base of the Kanto Plain, some 2500 to 3000 m below sea level. Much of the Kanto Plain surface is at sea level. By the early 1970s, with increasing urbanization and industrial expansion, local overdraft of groundwater resources caused major ground subsidence and damage to commercial and residential structures as well as to local and regional infrastructure. Parts of the lowlands around Tokyo subsided to 4.0 m below sea level; particularly affected were the suburbs of Funabashi and Gyotoku in western Chiba. In the southern Kanto Plain, regulations, mainly by local government and later by regional agencies, led to installation of about 500 monitoring wells and almost 5000 bench marks by the 1990's. Many of them are still working with new monitoring system. Long-term monitoring is important. The monitoring systems are costly, but the resulting data provide continuous measurement of the "health" of the Kanto Groundwater Basin, and thus permit sustainable use of the groundwater resource.
Subsidence characterization and modeling for engineered facilities in Arizona, USA
Authors: Rucker M. L. , Fergason K. C. , Panda B. B.
Published: November 2015

Abstract. Several engineered facilities located on deep alluvial basins in southern Arizona, including flood retention structures (FRS) and a coal ash disposal facility, have been impacted by up to as much as 1.8 m of differential land subsidence and associated earth fissuring. Compressible basin alluvium depths are as deep as about 300 m, and historic groundwater level declines due to pumping range from 60 to more than 100 m at these facilities. Addressing earth fissure-inducing ground strain has required alluvium modulus characterization to support finite element modeling. The authors have developed Percolation Theory-based methodologies to use effective stress and generalized geo-material types to estimate alluvium modulus as a function of alluvium lithology, depth and groundwater level. Alluvial material modulus behavior may be characterized as high modulus gravel-dominated, low modulus sand-dominated, or very low modulus fines-dominated (silts and clays) alluvium. Applied at specific aquifer stress points, such as significant pumping wells, this parameter characterization and quantification facilitates subsidence magnitude modeling at its' sources. Modeled subsidence is then propagated over time across the basin from the source(s) using a time delay exponential decay function similar to the soil mechanics consolidation coefficient, only applied laterally. This approach has expanded subsidence modeling capabilities on scales of engineered facilities of less than 2 to more than 15 km.

Published: November 2015

Abstract. In this study we investigate different aspects of land subsidence and ground failures occurring in the west portion of Chapala lake basin. Currently, surface discontinuities seem to be associated with subsiding bowls. In an effort to understand some of the conditioning factors to surface deformation, two sounding cores from the upper sequence (11 m depth) were extracted for analyzing physical and mechanical properties. The upper subsoil showed a predominant silty composition and several lenses of pumice pyroclastic sand. Despite the relative predominance of fine soil, the subsoil shows mechanical properties with low clay content, variable water content, low plasticity and variable compressibility index, amongst some others. Some of these properties seem to be influenced by the sandy pyroclastic lenses, therefore, a potential source of the ground failure could be heterogeneities in the upper soil.

Published: November 2015

El artículo analiza la contribución de la novela histórica Monja y casada, virgen y mártir de Vicente Riva Palacio en la construcción de un imaginario nacionalista liberal atravesado por amplias desigualdades sociales, étnicas y de género. Para ello, se aborda la estrategia narrativa desarrollada en la obra, centrando la atención en la verosimilitud pretendida y en los perfiles sociales dibujados en la misma, relacionando estos elementos literarios con el marco histórico contemporáneo en el que fueron producidos. Su selección responde a la extraordinaria influencia que tuvo en la creación de la identidad nacional mexicana, la regulación de la feminidad en la construcción liberal y el mito que convirtió a la Inquisición en sinónimo de intolerancia, crueldad y opresión.
Las primeras formas del Indigenismo en Argentina: la voz de sus precursores
Authors: Nicolás Alba María del Carmen
Published: November 2015

Los discursos narrativos en busca de una identidad nacional que se fueron produciendo en Argentina después de la Organización Nacional coincidieron con la llegada masiva de inmigrantes y la finalización de la Conquista del Desierto, con la que se consiguió, si no exterminar, sí asimilar a miles de indígenas. Sin embargo, ante la excesiva cosmopolitización de Buenos Aires, surgieron voces que clamaban por una autenticación de la argentinidad. Ciertos escritores del interior que ya contaban con el beneplácito de la intelectualidad bonaerense comenzaron a publicar discursos nativistas como oposición a las nuevas tendencias extranjerizantes en un intento por la rehabilitación de una tradición nacional y en un espacio editorial menos competitivo, pero también como un retroceso al pasado bucólico que solo el interior del país podía representar. En este artículo se abordarán los discursos regionalistas que dieron voz a la realidad indígena que había sido olvidada como depositaria de la identidad nacional, como las obras de Joaquín V. González y de Ricardo Rojas. Estos discursos, junto a las indagaciones arqueológicas de Juan Bautista Ambrosetti, Lafone Quevedo y Adán Quiroga, contribuyeron a revalorizar el pasado indígena argentino y a renovar la imagen del indio quien, sin embargo, aún sufría la invisibilidad y la explotación, hechos que sí supo ver aisladamente Juana Manuela Gorriti en su cuento “Si haces mal no esperes bien” de 1860. Aunque la denuncia social en la literatura se produjo algunas décadas más tarde, las tendencias herderianas de principios de siglo sirvieron de acicate para un desarrollo posterior plenamente indigenista.
La imagen de la ruina en "Los elementos de la noche [1958-1962]" de José Emilio Pacheco
Authors: Pascual Battista Rosario
Published: November 2015

La imagen de la ruina es una de las figuraciones recurrentes a través de la cual se valida la reconstrucción de lo perdido en la poesía de José Emilio Pacheco (1939-2014). Mediante los restos, por ejemplo, de los edificios o lugares destruidos por los conquistadores (tal es el caso de la ciudad prehispánica de Tenochtitlan) se comienza a elaborar una red que enlaza las pérdidas y las ausencias con sus consecuentes olvidos. Frente a una historia hecha a partir del encadenamiento de una serie de sucesos infaustos, la figura del poeta contrarresta, con sus creaciones poéticas, las destrucciones del pasado. Las ruinas, a pesar de significar, a veces, un pasado glorioso y prestigioso, el de los pueblos precolombinos, marcan la violencia y la desidia con que actuaron los conquistadores sobre el suelo latinoamericano. La propuesta de este trabajo se sostiene en identificar, analizar y explicar las imágenes poéticas y los recursos literarios que José Emilio Pacheco emplea en algunos poemas de su libro Los elementos de la noche [1958-1962] (1963) al definir y diagramar los espacios de la ruina, la destrucción y la devastación en el ámbito mexicano.
The Recognizability of Recognition: Fragments in the Name of a Not Yet Rhetorical Question
Authors: Doxtader Erik
Published: November 2015

Shot through with Schlegel's insight that “words often understand themselves better than those who use them,” Walter's Benjamin's 1916 essay, “On Language as Such and on the Language of Man” extends an invitation to reflect on those words that speak to the recognizability of language, the name of that in which language abides and discloses itself. For now, a century after it was first composed as an unsent letter, a close consideration of Benjamin's important essay sheds light on the contemporary question of recognition, the not yet rhetorical question of how the ethical-political stakes of recognition may hinge on the (dis)possession of (its) language.
Reconnaissances of Marx
Authors: Salazar Philippe-Joseph
Published: November 2015

This article is about recognizing the territory of a concept, in this case, that of Marxism as it appears in the Theses on Feuerbach, by summoning up Deleuze, Freud, Engels, Heidegger, and Sartre. Rhetoric analysis is applied to the foundational scripture of Marxism to show how Marx's materialist enunciation was thwarted by Engel's textual manipulation.
When the Call Is Not Meant for You: Misinterpellation, Subjectivity, and the Law
Authors: Martel James R.
Published: November 2015

In this article, I argue that Althusser's theory of interpellation suggests, however obliquely, a way to subvert and ruin the formation of subjectivity under liberal capitalism. For Althusser, when the law calls the subject, “nine times out of ten” the person called is “really” the one that the law intended. This article asks about the one in ten who is not the one whom the law wanted but who answers the call anyway. This is what I am calling the misinterpellated subject. I argue that this subject, because she or he is unwanted and unexpected, rhetorically ruins the scene of interpellation, offering a potentially radical source of resistance to liberal capitalism. Looking at Althusser's work on interpellation along with critics like Judith Butler and Lauren Berlant, I seek to show how the occasional flaws in interpellation (the one in ten) can be expanded by developing an anarchist politics as well as anarchist forms of subjectivity.
Thinking of a Utopian Future:
Authors: Pro Juan
Published: November 2015

Fourierist utopianism really took root in nineteenth-century Spain. The original focal point in Cádiz had echoes in Cartagena, Granada, Madrid, and Valladolid. Apart from spreading Fourier's ideas, these Spanish Fourierists tried to set up several utopian communities (known as phalansteries) and published books and newspapers, in which—among other things—we find the first signs of feminism in the Spanish language. For all these reasons, Spanish Fourierism may be considered an important chapter in the history of utopian socialism. As it had to do with a drive for freedom and daring in thought, the movement could be very flexible and was capable of associating with other doctrines, such as romanticism, feminism, and spiritism. Whereas the most political branch of Spanish Fourierism is related to the Democratic Party, republicanism, and the roots of Marxist socialism (Partido Socialista Obrero Español, the Spanish Socialist Party, founded in 1879), the libertarian drive implicit in setting up utopian communities lived on in anarchism.
The Harmonic Utopia of Spanish Republicanism (1840–1873)
Authors: Peyrou Florencia
Published: November 2015

Ever since they first appeared in the public sphere, around 1840, and until the First Republic was proclaimed in 1873, Spanish republican activists never ceased to spread in newspapers and political pamphlets the idea that a republic would entail a “supreme synthesis of the political contradictions of our century” and “the conciliation of all hatred and all rivalry, the harmony of all interests.” This article sets out to study what may be dubbed the “utopian dimension” of the collective imagination of Spanish republicanism (the aspiration to total political and social unity) and its consequences for the political culture and practice of Spanish republicans.
Utopian Views of Spanish Zarzuela
Authors: Ferrera Carlos
Published: November 2015

The article addresses zarzuela, a musical and theatrical genre that was very popular in Spain at the end of the nineteenth century and beginning of the twentieth, in which we can see plentiful examples of a “utopian impulse.” In its comical way it portrayed society by satirically turning it on its head, a tradition that dates back to Swift, among others, and gave vent to social criticism against the liberal order of the mid-nineteenth century. Years later, zarzuelas trumpeted an ideal of national and social harmony, although they simultaneously warned of potentially dystopian situations caused by workers' and gender demands or breakaway tendencies in some regions.

Social Media Use, Engagement and Addiction as Predictors of Academic Performance
Authors: Al-Menayes Jamal J.
Published: November 2015

This study investigated the effect of social media usage, engagement, and addiction on academic performance. First, the results show that the amount of time one spends using social media affects academic performance in a negative way. The amount of time one spends using social media is negatively correlated with their academic performance. Second, the study examined the effect of social media engagement on academic performance. Results show the SMEQ had no significant impact on academic performance. This outcome indicates that, unlike social media usage, being engaged alone does not affect academic performance. Finally, the study looked at social media addiction and its effect on academic performance. Social Media Addiction Scale (SMAS) was used for this purpose. Factor analysis was again used to determine the dimensions of SMAS. The analysis yielded three factors. Two of these factors were negative predictors of academic performance. This is not surprising since addiction implies heavy usage that previously showed the same negative effect on academic performance.
