S’émanciper loin de ses repères culturels et familiaux ou devenir mère pour être femme…
Authors: Vendroux Sabrina , Idris Isam
Published: November 2018

Envisagée comme voie possible d’émancipation féminine, la migration s’avère une source de désillusion. Elle contraint à une nécessaire transformation de soi impliquant épreuves et sacrifices. La grossesse, pour paradoxale qu’elle soit dans ce contexte, offre, par son caractère initiatique, une perspective vers la subjectivation. Le passage par le maternel, en permettant de penser la séparation-différenciation de la terre-mère d’origine, met la femme à l’épreuve de sa propre existence au monde, d’ici comme celui de là-bas. Le cas d’une jeune Ivoirienne aux prises avec une maternité non désirée permet de repérer l’occurrence élaborative que représente la grossesse dans le contexte de la migration.
Impact of Time to Anti-Vascular Endothelial Growth Factor Intervention on Visual Outcomes for Patients Diagnosed With Retinal Vein Occlusion
Authors: Hsueh Jessica , Wai Karen M. , Conti Felipe F. , Conti Thais F. , Singh Rishi P.
Published: November 2018

BACKGROUND AND OBJECTIVES:

To analyze the impact of time to treatment with anti-vascular endothelial growth factor (VEGF) for patients with macular edema (ME) secondary to retinal vein occlusions (RVO) in routine clinical practice.

PATIENTS AND METHODS:

One hundred fifty-five eyes with ME secondary to RVO were identified. Patients were divided into initiation of anti-VEGF treatment at 28 days or fewer after symptom onset (Group A), between 28 and 84 days (Group B), and 84 days or more (Group C).

RESULTS:

A significant central subfield thickness (CST) decrease at 12 months was observed in Groups A, B, and C (−184.14 µm, −204.55 µm, and −170.71 µm, respectively;
P
< .001). At 12 months, Groups A and B showed significant BCVA improvement (19.14 and 21.11, respectively;
P
≤ .001), whereas Group C showed no significant improvement from baseline (4.01;
P
< .28).

CONCLUSIONS:

Anatomical response as measured by CST did not differ between groups, whereas delays in treatment resulted in smaller BCVA improvement with anti-VEGF treatment.

Outer Retinal Tubulation and Neovascular Age-Related Macular Degeneration: A Review of the Pathogenesis and Clinical Implications
Authors: Damasceno Nadyr A. , Damasceno Eduardo F. , Silva Fabiana Q. , Singh Rishi P.
Published: November 2018

Outer retinal tubulation (ORT) is a retinal finding that can mimic intraretinal fluid and has been identified with spectral-domain optical coherence tomography in patients with age-related macular degeneration (AMD). The purpose of this review is to summarize the findings related to the pathogenesis of ORT and its clinical implications. Studies reporting the pathogenesis and the clinical implications of ORT in patients with AMD were identified and summarized. A total of 18 studies were included in this review. The body of evidence to date regarding ORT in patients with AMD indicates that ORT is a structure associated with advanced macular diseases that does not require anti-vascular endothelial growth factor treatment.

Authors: Motulsky Elie H. , Zheng Fang , Shi Yingying , Gregori Giovanni , Rosenfeld Philip J.
Published: November 2018

BACKGROUND AND OBJECTIVE:

Swept-source optical coherence tomography angiography (SS-OCTA) and different boundary-specific segmentation strategies were used to distinguish type 1 macular neovascularization (MNV) from type 2 MNV in eyes with exudative age-related macular degeneration (AMD).

PATIENTS AND METHODS:

Eyes with exudative AMD were enrolled in a prospective study. Segmentation strategies included a slab from the outer retina (OR) to the choriocapillaris (CC) for the entire MNV, a slab from the retinal pigment epithelium (RPE) to the CC for the type 1 MNV, and a slab from the OR to the RPE for the type 2 MNV.

RESULTS:

In 13 eyes, SS-OCTA B-scans and en face images using different segmentation strategies were able to identify type 1 and type 2 components of the MNV.

CONCLUSION:

In eyes with exudative AMD, SS-OCTA imaging and commercially available boundary-specific segmentation strategies were used to distinguish between type 1 and type 2 MNV.

Bilateral Vitreous Hemorrhage Following Bilateral Intravitreal Injections of Bevacizumab in an Infant With Retinopathy of Prematurity
Authors: Theophanous Christos , Schechet Sidney , Rodriguez Sarah Hilkert , Blair Michael
Published: November 2018

Since the publication of BEAT-ROP in 2011, intravitreal bevacizumab (IVB) has become increasingly common for the treatment of posterior type 1 retinopathy of prematurity (ROP). However, long-term data on the safety and efficacy of IVB for ROP are lacking. Vitreous hemorrhage following bevacizumab injections have been rarely reported in infants with ROP, and the need for treatment of these hemorrhages remains in question. Here, the authors report a case of bilateral vitreous hemorrhage in a premature infant within 2 weeks of bilateral intravitreal injections of bevacizumab. These hemorrhages resolved without intervention with regression of ROP in both eyes.

Quantitative Comparison Between Optical Coherence Tomography Angiography and Fundus Fluorescein Angiography Images: Effect of Vessel Enhancement
Authors: Mochi Thirumalesh , Anegondi Neha , Girish Molleti , Jayadev Chaitra , Sinha Roy Abhijit
Published: November 2018

BACKGROUND AND OBJECTIVE:

To compare the vascular parameters derived from optical coherence tomography angiography (OCTA) and fundus fluorescein angiography (FFA) images.

PATIENTS AND METHODS:

Twenty-two eyes of 22 patients were imaged with OCTA and FFA. FFA images were cropped to the same dimension as OCTA images after registration. Vessel enhancement using a Frangi filter and local fractal analysis was applied to the superficial layer of the OCTA and cropped FFA images. Foveal avascular zone (FAZ) area, vessel density, spacing between large vessels, and spacing between small vessels were quantified.

RESULTS:

FAZ area was similar between original OCTA, Frangi-filtered OCTA, and FFA images (P = .32). Actual OCTA images had significantly higher vessel density (35.2% ± 1.45%,
P
< .001) than Frangi-filtered OCTA images (29.8% ± 0.78%) and Frangi-filtered FFA images (25.5% ± 2.41%). Spacing between large vessels was significantly lower in original OCTA images (31.9% ± 1.47%,
P
< .001) than Frangi-filtered OCTA images (36.8% ± 1.24%) and Frangi-filtered FFA images (60.1% ± 2.68%). Further, FFA images had significantly lower spacing between small vessels (14.4% ± 0.43%,
P
< .001) than original OCTA images (32.7% ± 1.03%) and Frangi-filtered OCTA images (33.4% ± 0.81%).

CONCLUSION:

FAZ area was similar between OCTA and FFA, independent of vessel enhancement. However, vessel enhancement improved the agreement of vascular parameters between OCTA and FFA images of the same eye.

Visualizing Structure and Vascular Interactions: Macular Nonperfusion in Three Capillary Plexuses
Authors: Park Justin J. , Chung Christopher S. , Fawzi Amani A.
Published: November 2018

BACKGROUND AND OBJECTIVE:

To assess the relationship between retinal vascular and structural changes in the superficial, middle, and deep capillary plexuses (SCP, MCP, DCP) using optical coherence tomography angiography (OCTA) and en face OCT.

PATIENTS AND METHODS:

Patients with diabetic retinopathy were imaged using the Cirrus HD-OCT with AngioPlex. Using manual segmentation of the retinal layers, the authors compared OCTA to en face OCT images to examine corresponding patterns in each of the three capillary plexuses.

RESULTS:

Areas of decreased perfusion and capillary dropout on OCTA were found to be associated with three corresponding lesions on en face OCT: hyporeflectivity, cystic edema, and hard exudates. Vascular changes in individual capillary plexuses corresponded with structural changes in their respective perfused retinal layers.

CONCLUSIONS:

Using manual segmentation on OCTA, the authors provide a framework to visualize the relationship between vascular pathology on OCTA and structural changes on en face OCT within specific capillary plexuses.

If the Gear Fits, Spin It Again!
Authors: Johnson Mina C. , Birchfield David , Megowan-Romanowicz Colleen
Published: November 2018

To understand how students learn while engaged in active and embodied science games, two gears games were created. Would students' gear switching skills during the game be correlated with pre- and post-knowledge tests? Twenty-three seventh graders, playing as dyads, used gestures to manipulate virtual gears in the games. The Microsoft Kinect sensor tracked arm-spinning movements. Paper and pencil gear knowledge tests were administered before and after. In Game 1 (the easier one), the in-game switching data was significantly negatively correlated with only pretest gear knowledge. In Game 2 (the harder one), switching was negatively associated with both pre- and posttests. Negative correlations mean that fewer switches were used and that demonstrated better knowledge of mechanical advantage. In-game process data can provide a window onto learner's knowledge. However, the games need to have appropriate sensitivity and map to the learner's ZPD. In ludo (or in-process) data from videogames with high sensitivity may attenuate the need for repetitive traditional knowledge tests.
Comparison of Inductive Inference Mechanisms and their Suitability for an Information Model for the Visualization of Uncertainty
Authors: Weber Moritz , Staudter Georg , Anderl Reiner
Published: November 2018

Ontologies represent inter-related semantic information. The automated integration of new knowledge helps to detect and reduce data-induced conflicts and model-based uncertainty in ontologies. However, automatic extension of an existing ontology from heterogeneous distributed sources can often lead to incomplete and contradictory entities. In order to resolve these conflicts and to complete entities, inductive inference mechanisms should be applied in addition to the deductive mechanisms already in use. This paper first describes various inductive inference mechanisms and compares these with each other according to pre-defined requirements and other criteria. Finally, the mechanisms’ suitability for an information model for the exchange and visualization of uncertainty in load-carrying systems and possible combinations of the individual mechanisms are discussed, also with respect to the necessity of further modifications of these mechanisms.

Published: November 2018

Resilience as a concept has found its way into different disciplines to describe the ability of an individual or system to withstand and adapt to changes in its environment. In this paper, we provide an overview of the concept in different communities and extend it to the area of mechanical engineering. Furthermore, we present metrics to measure resilience in technical systems and illustrate them by applying them to load-carrying structures. By giving application examples from the Collaborative Research Centre (CRC) 805, we show how the concept of resilience can be used to control uncertainty during different stages of product life.
Simulation of Multi-Stage Fine Machining Processes at the Example of Valve Guide and Valve Seat
Authors: Bölling Christian , Abele Eberhard
Published: November 2018

Fine machining processes are of great importance in automotive series production, e.g. the machining of valve guide and seat in the cylinder head of a combustion engine. In industrial manufacturing processes, disturbances are inevitable and provide a measure of uncertainty in each production step. Increasingly, the influence of such uncertainties is being evaluated using simulation models. In this paper, a modeling approach for simulation of multi-stage fine machining processes with step tools is presented and investigations regarding influence of uncertainty caused by disturbances are performed.
Inverse Interval Field Quantification via Digital Image Correlation
Authors: Faes Matthias , Moens David
Published: November 2018

This paper presents the application of a new method for the identification and quantification of interval valued spatial uncertainty under scarce data.Specifically, full-field strain measurements, obtained via Digital Image Correlation, are applied in conjunction with a quasi-static finite element model.To apply these high-dimensional but scarce data, extensions to the novel method are introduced.A case study, investigating spatial uncertainty in Young's modulus of PA-12 parts, produced via Laser Sintering, shows that an accurate quantification of the constituting uncertainty is possible, albeit being somewhat conservative with respect to deterministic values reported in literature.
Reducing Uncertainty in Shunt Damping by Model-Predictive Product Stiffness Control in a Single Point Incremental Forming Process
Authors: Hoppe Florian , Knoll Maximilian , Götz Benedict , Schaeffner Maximilian , Groche Peter
Published: November 2018

The stiffness of metal formed products strongly affects the dynamic behavior of structures in which they are integrated. Forming processes underlie short and long-term variations which cause the stiffness to be uncertain.In the application of resonant shunted piezoelectric transducers for vibration attenuation, uncertain stiffness may cause significant reduction in the vibration attenuation performance due to imprecise tuning. In the past, large efforts were made to control one or more geometrical feature of products while weightier features that cause uncertainty have not been addressed.In this paper, a single point incremental forming process of a membrane-like spring element on a servo press with a 3 degrees of freedom drive system is investigated. This spring element is used in a beam support for lateral vibration attenuation with resonant shunted transducers as well as axial buckling stabilization.To reduce uncertainty caused by process variations, an offline closed-loop control of product stiffness is presented. Different product and forming criteria are integrated into a control approach based on an optimization routine. By making use of a model-based prediction of the product properties, the approach shows how to realize a multi-objective control.

Investigation on Forming Behaviour of Sheet Metal by Test Using Cylindrical Cup with Hole
Authors: Watcharasresomroeng Bhadpiroon
Published: November 2018

Nowadays, there are several grades of sheet metal used in the automotive industry. Highstrength steel sheets, particularly, have been widely used in order to reduce the weight of vehicles,which is strongly related to their fuel consumption rate. However, it is generally known that thestrength of the sheets, which is relatively higher than that of the conventional carbon steel sheets,results in their low formability. In this work, the limiting drawing ratio and forming behavior of sheetmetal that is conventionally used for automobile parts were evaluated by test using cylindrical cupwith hole. The feasibility to use limiting cup height for comparing formability of sheet metal was alsoincluded in the investigation. The sheet materials used in the experiments are aluminium, cold rolledsteel, high strength steel and advanced high strength steel. The process parameters for this study weredie corner radius and blank holder force. Workpiece materials were prepared with a circular shapeand with a diameter of 80 millimetres. In the center of the circular workpiece, a 12-millimetrediameter hole was drilled to observe the formability of each of the materials. The advantage of usingan initial blank with a hole in the center by the cylindrical cup drawing test is that the cup does notfail from changes of the thickness of material near the punch radius at the bottom of the cup. Thelimiting cup height of the investigated materials were evaluated by test using the cylindrical cup withhole. The results show that the limiting cup height values have a relationship to the limiting drawingratio values of the investigated materials. Testing using cylindrical cup with hole by evaluating thelimiting cup height value is feasible for comparing the formability of sheet metals.

Authors: Anwar Miftahul , Saraswati Teguh Endah , Bahrudin Ahmad
Published: November 2018

This study describes the structural modifications of char electrodes and the resulting carbon nanoparticles using method of arc discharge in liquid method, an approach which is simpler and less expensive than other techniques such as CVD and laser vaporization. The nanoparticles are obtained from powder floating on the water surface during arc discharge between two electrodes submerged in water. X-ray diffraction analysis (XRD) profiles show peak formation at 24-26o2Ѳ, associated with hexagonal graphite structure.Transmission electron microscopy (TEM) confirmed the presence of graphitic-structured nanoparticles after arc discharge; these nanoparticles have diameters ranging from 20 to 100 nm. In contrast, nanoparticles produced using graphite electrodes with current source variations show more complicated and varied stuctures, for example, structures such as nanoonions, graphene, and amorphous nanoparticles.
Improvement on Dispersion of Carbon Nanotubes in Polymer Matrix by Using the Solvent with a Low Boiling Point
Authors: Fu Xiang , Ramos Maximiano , Al-Jumaily Ahmed M. , Huang Xi Yong , Chowdhury Nargis
Published: November 2018

Polymer nanocomposites based on carbon nanotubes attract a great deal of attention recently due to their excellent performance. The dispersion state of CNTs embedded in the matrix is the primary and key issue to realize the potential of the nanocomposite. Here, this paper considers how the boiling point of solvent affects the performance of the nanocomposite when the ultrasonication dispersion method is employed. It is found that solvent with a low boiling point is conducive to save evaporation time so that CNTs can maintain the homogenous dispersion state as much as possible after ultrasonication. Therefore, the stretchability and tensile strength can be improved, while the electrical conductivity has an obvious enhancement as well.
CFRP Bonding Pre-Treatment with Laser Radiation of 3 μm Wavelength: A Robust Solution for Industrial Applications
Authors: Blass David , Nyga Sebastian , Jungbluth Bernd , Hoffmann Hans Dieter , Dilger Klaus
Published: November 2018

Due to a reduced structural weight, composite parts offer the possibility to increase the eco-efficiency of any mobility devices during their lifetime. Due to the mold-based production of composite parts, their surfaces are contaminated with release agent residues (e.g. silicones). Thus, the adhesion of the part’s surface is lowered, which prevent structural adhesive bonding of untreated parts. To enable this joining technology and guarantee a sufficient adhesion during part’s lifetime, a surface pre-treatment prior to the bonding process has to be performed. A laser treatment shows a high potential for an integration in an industrial process chain, but unfortunately, common laser sources lower this potential due to high investment costs (excimer laser) or the risk of causing material damage (lasers emitting in the range of 1 μm wavelength). To solve this challenge, laser radiation at 3 μm wavelength, which has several advantages (high absorption within epoxy resin, less thermal interaction concluding less risk to cause delaminations and the possibility to be guided through a fiber) was generated by frequency conversion of an industrial ND:YAG laser (at 1064 nm) and applied to the composite. The results show a good and sensitive treatment of the surface, resulting in high bonding strengths and providing a robust pre-treatment method.
An Empirical Model for Prediction of Residual Stress Based on Grinding Forces
Authors: Guo Wei Cheng , Li Bei Zhi , Shen Shou Guo , Wu Chong Jun , Hu Jun
Published: November 2018

Residual stress has a significant influence on mechanical strength of a manufactured part and is considered to be related with process parameters and grinding signals. This paper investigates the relationship between residual stress and forces in the grinding of maraging steel 3J33. Features in time and frequency domains are extracted from tangential and normal grinding forces via various signal processing techniques. A two-round selection based on the statistical criterion is proposed to choose the best features that are related to the residual stress in the surface layer. The selected features are combined linearly in order to develop an empirical regression model that is capable of predicting residual stress well. The predicted residual stress values are compared with those measured from the experiment performed under different process parameters, and the result shows a favorable agreement quantitatively.

Exploring the possibility for African traditional religion to be included in a reimagined scriptural reasoning model
Authors: Sukdaven Maniraj
Published: November 2018

In and among the many models developed for engaging in inter-religious dialogue was a model that became known as scriptural reasoning (SR). SR basically serves the purpose of being hospitable towards the Abrahamic religions. The current approach of SR, by virtue of its focus only on scripture as the basis of engagement, obviously excludes other faith traditions that possess no sacred scripture. One such religion is African traditional religion (ATR). As a result of this exclusion, this article intends to engage SR to consider reinterpreting imaginatively, or to use a synonym, to reconceptualise, its basis of only scripture as the primary source of engagement and as such to expand its basis to include religions with an oral-orientated tradition. This article explores such a possibility for the inclusion of ATR, as an oral tradition, to be considered as an equal partner in a reimagined SR or as a parallel model with similar guidelines and outcomes as found in SR.

Published: November 2018

The Global Malarial Action Plan (GMAP) addresses different measures towards achieving complete elimination of malaria, the most dangerous vector-borne disease. Present efforts for prevention and treatment of malaria in Cape Coast, a small town in southern Ghana, has achieved significant improvement from the past in controlling both the morbidity and mortality rates through various approaches. However, the current efforts and methodology in proceeding towards elimination of malaria presents many unanswered questions in terms of its level of sustainability. This report provides an overview of the current strategies implemented and addresses multifactorial issues that impede the control and eradication of malaria in Cape Coast. In addition, the effectiveness and sustainability of these strategies to achieve such intended goals have been evaluated. This study was conducted within Cape Coast, Ghana among 2 rural villages, Cape Coast Teaching Hospital and the general populous. Data collection involved face-to-face interviews of 55 individuals residing in Cape Coast, as well as, the use of hospital records on malaria. The paper concludes by indicating that more funding in infrastructure, as well as, serious advancement in public action is essential for improved malarial control and complete elimination of the disease.Keywords: DDT: Dichlorodiphenyltrichloroethane, GMAP: Global Malaria Action Plan, IRS: Indoor residual spraying (insecticide), ITN: Insecticide-treated nets, LBW: Low birth weight, LLIN: Long-lasting insecticide-treated nets, LSM: Larval Source Management, NHIS: National Health Insurance Scheme, Pf: Plasmodium Falciparum, WHO: World Health Organization
Interrogating heterosis and consanguinity for livestock and human populations
Authors: Aneni Monica Omoye , Antigha Essien
Published: November 2018

Heterosis or hybrid vigour is an increase in the yield of a hybrid animal over those of its parents; and consanguinity, the quality of being descended from the same ancestor as another person; have been discussed independently by scholars. However, this study attempts a side by side investigation of heterosis and consanguinity as they affect livestock and human populations in antiquity and Nigeria, with a view to understanding how these cultures/strategies can positively or negatively affect the progress and prosperity of a society. The social development theory is adopted to further present an expansionary view on how society can grow and prosper with regard to these themes. The argument that heterosis or exogamy is more advantageous than consanguinity for the growth of a society is put forward in the discourse. Further studies may examine excessiveness in heterosis with regard to human development even in antiquity and Nigeria.Keywords: Heterosis, consanguinity, livestock and human populations, antiquity, Nigeria
Energy consumption and saving potential in cement factory: thermal energy auditing
Authors: Gebreslassie M.G. , Gebrelibanos K.G. , Belay S
Published: November 2018

Energy is one of the major inputs for the economic development of any country, thus lack of efficient and effective utilization of energy is a major concern in high-energy consuming industries such as the cement industries. The objective of this research is therefore to conduct energy auditing in Messobo Cement Factory to quantify the energy losses in the system and to identify potential areas for improvement. On site measurements of the material and energy flows was conducted using Infrared thermometer, Thermocouples and Pitot static probe with manometer. Based on the energy analysis performed, the most energy intensive process is found to be the pyre system (burning). The specific heat consumption has been found to be 844.5 kcal/kg-cl with around 45.83 % system efficiency. The major heat losses for the processes occurred in pre - heater exhaust gases and grate cooler vent air that accounted as 176.7 kcal /kg-cl and 199.3 kcal/kg-cl respectively. Comparison of the specific heat consumption with the standard specific heat consumption of the technology under study (730-780 kcal/kg-cl) showed about 64.5 kcal/kg-cl more energy consumption in the kiln system. This indicates that there is a need to improve the energy consumption by applying proper energy saving techniques.Keywords: Rotary Kiln; Heat balance; Auditing; Efficiency
Film Serials and the American Cinema, 1910-1940
Authors: Brasch Ilka
Published: November 2018

Before the advent of television, cinema offered serialized films as a source of weekly entertainment. This book traces the history from the days of silent screen heroines to the sound era's daring adventure serials, unearthing a thriving film culture beyond the self-contained feature. Through extensive archival research, Ilka Brasch details the aesthetic appeals of film serials within their context of marketing and exhibition, looking at how they adapted the pleasures of a flourishing crime fiction culture to both serial visual culture and the affordances of the media-modernity of the early 20th century. The study furthermore traces the relationship of film serials to the broadcast models of radio and television and thereby shows how film serials introduced modes of storytelling that informed popular culture even beyond the serial's demise.

Abstract. A hygroscopic tandem differential mobility analyzer (HTDMA), a
scanning mobility cloud condensation nuclei (CCN) analyzer (SMCA), and an Aerodyne high-resolution
time-of-flight aerosol mass spectrometer (HR-ToF-AMS) were used to,
respectively, measure the hygroscopicity, condensation nuclei activation, and
chemical composition of aerosol particles at the Panyu site in the Pearl
River Delta region during wintertime 2014. The distribution of the size-resolved
CCN at four supersaturations (SSs of 0.1 %,
0.2 %, 0.4 %, and 0.7 %) and the aerosol particle size distribution
were obtained by the SMCA. The hygroscopicity parameter κ (κCCN, κHTDMA, and κAMS) was,
respectively, calculated based upon the SMCA, HTDMA, and AMS measurements. The results
showed that the κHTDMA value was slightly smaller than the
κCCN one at all diameters and for particles larger than
100 nm, and the κAMS value was significantly smaller than the others
(κCCN and κHTDMA), which could be attributed to
the underestimated hygroscopicity of the organics (κorg). The
activation ratio (AR) calculated from the growth factor – probability
density function (Gf-PDF) without surface tension correction was found to be
lower than that from the CCN measurements, due most likely to the
uncorrected surface tension (σs∕a) that did not consider the
surfactant effects of the organic compounds. We demonstrated that better
agreement between the calculated and measured ARs could be obtained by
adjusting σs∕a. Various schemes were proposed to predict the
CCN number concentration (NCCN) based on the HTDMA and AMS
measurements. In general, the predicted NCCN agreed reasonably well
with the corresponding measured ones using different schemes. For the HTDMA
measurements, the NCCN value predicted from the real-time AR
measurements was slightly smaller (∼6.8 %) than that from
the activation diameter (D50) method due to the assumed internal mixing
in the D50 prediction. The NCCN values predicted from bulk
chemical composition of PM1 were higher (∼11.5 %) than
those from size-resolved composition measured by the AMS because a
significant fraction of PM1 was composed of inorganic matter. The
NCCN values calculated from AMS measurement were underpredicted at
0.1 % and 0.2 % supersaturations, which could be due to underestimation of
κorg and overestimation of σs∕a. For SS values of 0.4 %
and 0.7 %, slight overpredicted NCCN values were found because of
the internal mixing assumption. Our results highlight the need for
accurately evaluating the effects of organics on both the hygroscopic
parameter κ and the surface tension σ in order to accurately
predict CCN activity.
A perspective of counter-hegemonic analysis and territorial transformation
Authors: Saquet Marcos Aurelio
Published: November 2018

Abstract. This paper shows the results from my research trajectory and my
collaboration in cooperative projects with economically disadvantaged
people
of the urban periphery of Francisco Beltrão (Brazil). I initially reflect
on the relevance of an analysis of urban social movements, asking how current
urban conflicts can be understood from a territorial perspective. I will
first develop a specific definition of territory, which seeks to become
operative in collaboration with diverse subjects and in the
analysis of territorial development based on the place. Such a
conceptualization of territory provides a territorial analysis furthering
transformation towards a fairer, solidary, and ecological society. I show how
this fairer society emerges in a multidimensional way, emanating
from the processes of territorialization, deterritorialization, and
reterritorialization. Finally, by linking these processes with the
current processes of territorial development (in research, analysis, and
active participation), this study contributes to a more dialogical and
counter-hegemonic perspective, especially in relation to Latin America.
Probable maximum precipitation estimation in a humid climate

Abstract. Probable maximum precipitation (PMP)
estimation is one of the most important components for designing hydraulic
structures. The aim of this study was the estimation of 24 h PMP
(PMP24) using statistical and hydro-meteorological (physical) approaches
in the humid climate of the Qareh-Su basin, which is located in the northern
part of Iran. Firstly, for the statistical estimate of PMP, the equations of
empirical curves of the Hershfield method were extracted and the Hershfield
standard and modified methods were written in Java programming language, as a
user-friendly and multi-platform application called the PMP Calculator.
Secondly, a hydro-meteorological approach, which is called the convergence
model, was used to calculate PMP24. The results of both approaches were
evaluated based on statistical criteria, such as the mean absolute error
(MAE), mean squared error (MSE), root mean squared error (RMSE), mean
absolute percentage error (MAPE), correlation coefficient (r), and
coefficient of determination (R2). The maximum values of PMP24 for
the Hershfield standard and modified methods were estimated to be 448 and
201 mm, respectively, while the PMP obtained by the physical approach was
143 mm. Comparison of PMP24 values with the maximum 24 h precipitation
demonstrated that based on performance criteria including the MAE, MSE, RMSE,
MAPE, r, and R2, the physical approach performed better than the
statistical approach and it provided the most reliable estimates for PMP.
Also, the accuracy of the Hershfield modified method was better than the
standard method using modified Km values, and the standard method
gives excessively large PMP for construction costs.
Component Structure of Credit Default Swap Spreads and Their Determinants
Authors: Bhar Ramaprasad , Colwell David , Wang Peipei
Published: November 2018

In this paper, we decompose credit default swap (CDS) spreads into a transitory component and a persistent component and test how these components are affected by the theoretical explanatory variables. We find significant but differing impacts of these explanatory variables on the extracted components. For example, equity volatility seems to have a larger influence on the transitory component, suggesting that its effect may be mostly short-lived, while our proxy for illiquidity has a greater impact on the persistent component indicating its more enduring effect. Also, the slope of the yield curve has impacts with opposite signs on the two components and so our analysis thus helps address the conflicting results reported in earlier studies without such a component framework. These results indicate that a two-factor formulation may be needed to model CDS options.
“A worn, weary, discontented look”: The Influence of West Point and the Hudson River Valley on Poe
Authors: Claywell Gina
Published: November 2018

This article argues that the Hudson River Valley—and specifically West Point—influenced Poe's writing and specifically his 1831 Poems dedicated to the U.S. Corps of Cadets. The grandeur of West Point's locale, the mystical nature of the surrounding rocky cliffs, the deep verdant river valley, the “light from out the lurid sea/Streams up the turrets silently” of the widening river at Trophy Point, and West Point's castellated architecture had a strong impact on Poe. Despite the haunting beauty of the area, Poe, like many cadets who view the scene laid out before them with a jaundiced perspective, knew the “worn, weary, discontented” desire to be anywhere but there. Drawing on work by Russell, Hecker, and Thompson, among others, the article concludes by suggesting reasons why Poe left West Point.
Nurse anesthesia student’s personality characteristics and academic performance: A big five personality model perspective
Authors: Imus Frederick Scott
Published: November 2018

Purpose: The purpose of this correlational research was to assess the association between the Five Factor Model (FFM) of personality traits and the grade point average (GPA) of students enrolled in a nurse anesthesia program (NAP). This research was conducted to identify a more objective way to evaluate a prospective students’ personality that correlates with academic success in a NAP.Methods: The Program Directors of students enrolled in NAPs throughout the United States were randomly contacted to assist with the data collection. The FFM of personality traits inventory and question requesting the student to self-report their GPA were then forwarded to the student.Results: Upon completion, the data was analyzed using SPSS 22.0. The results demonstrated a significant correlation, indicating that the dimensions of personality were significantly related to GPA. The dimensions of personality accounted for 12% of the variance in GPA. An examination of individual regression coefficients revealed that the personality trait, conscientiousness, was significantly and positively related to GPA.Conclusions: Nurse anesthesia admission committees can use this personality inventory to better guide them in selecting candidates for their program. Used in conjunction with the more traditional admissions criteria; NAPs can be better positioned to select students more objectively that will be successful in their program, hence leading to lower attrition rates.
An Empirical Analysis of the Impact of Fiscal and Tax Incentives on Enterprise Technological Innovation - Taking Listed Companies on GEM as Examples
Authors: Yang Junda , Xia Yun , Yang Liu , Zhang Zhongtao
Published: November 2018

Enterprise technological innovation is the backbone of the transformation of economic development mode in China, the optimization of economic structure, and the realization of national innovative development strategy. In order to promote the transformation and upgrading of the economic structure and encourage the the development of technological innovation of enterprises, a series of fiscal and tax policies which encourage technological innovation are introduced in China. Although the fiscal and tax incentives are generally adopted by the governments of the world, the research conclusions of the academia on the implementation effect of fiscal and tax policies are not unified. For this reason, in this paper, based on the data of listed companies on the Growth Enterprise Market from 2011 to 2017, the STATA 14.0-version software is used to analyze the sample data, and the relationship between the current fiscal policies and technological innovation is explored. The study results show that the fiscal and tax incentives positively affect the technological innovation of enterprises, which provides an important theoretical basis for the government to further improve fiscal and tax policies. Finally, based on the previous research contents, the corresponding conclusions are summarized, and relevant suggestions for improving the fiscal and tax incentive policies are proposed.

In Ghana there are concerns that antibiotics may be used inappropriately to boost fish production, though no study has investigated this problem. To provide preliminary insights into public health aspects of the problem, we investigated the occurrence of antibiotic residues and antibiotic-resistant bacteria in Nile tilapia (Oreochromis niloticus), a fish commonly cultivated and consumed in Ghana. Two hundred Nile Tilapia fish were randomly sampled from four major markets in Accra, the capital city of Ghana. One hundred samples were screened for antibiotic residues using a microbial inhibition plate test that detects sixteen different antibiotics commonly used in animal husbandry and aquaculture. The other 100 samples were cultured for bacteria using direct culture methods, and the isolates were tested against seven antibiotics by the Kirby Bauer method. The overall prevalence of antibiotic residues in the fish samples was 7%. Bacteria that were isolated from the fish samples were Shigella sonnei (10%), Enterobacter cloacae (7%), Escherichia coli (6%), Salmonella Typhi (3%) and Klebsiella pneumoniae and Proteus mirabilis (2%). All bacteria isolated were susceptible to gentamicin and ciprofloxacin but resistant to ampicillin. Multi-drug resistance (ie resistance to three or more different classes of antibiotics) occurred in 86.7% of the isolates. Nile Tilapia sold in Accra is a source of multi-drug resistant bacteria. Consumption of the fish can also lead to significant exposure to antibiotic residues.
