Coordination Failure with Multiple-Source Lending, the Cost of Protection Against a Powerful Lender

We analyze how a firm might protect quasirents in an environment of imperfect capital markets, where switching lenders is costly to the borrower, and contracts are incomplete. As switching costs make the firm vulnerable to ex post exploitation, it may want to diversify lending. Multiple-source lending, however, suffers from coordination failure. An uncoordinated withdrawal of funds will force a financially distressed firm into bankruptcy even though it could have been rescued if lenders had stayed firm. We show that the gains from preventing renegotiation do outweigh the cost of coordination failure if a single lender has sufficient bargaining power.
Aripiprazole does not influence methamphetamine I.V.self-administration in rats

The behavioural sensitization to methamphetamine (MET) induced by 14 day intraperitoneal administration of methamphetaminedecreased the number of the drug doses self-administered per session. This finding might result from increasing efficacy of the drug after sensitization caused by repeated MET intermittent administration. However, aripiprazole did not influence MET intake neither in the behaviourally methamphetamine sensitized nor in the non-sensitized rats.
A semantic network model for measuring engagement and performance in online learning platforms

Due to the increasing global availability of the internet, online learning platforms such as Massive Open Online Courses (MOOCs), have become a new paradigm for distance learning in engineering education. While interactions between instructors and students are readily observable in a physical classroom environment, monitoring student engagement is challenging in MOOCs. Monitoring student engagement and measuring its impact on student performance are important for MOOC instructors, who are focused on improving the quality of their courses. The authors of this work present a semantic network model for measuring the different word associations between instructors and students in order to measure student engagement in MOOCs. Correlation analysis is then performed for identifying how student engagement in MOOCs affect student performance. Real‐world MOOC transcripts and MOOC discussion forum data are used to evaluate the effectiveness of this research.
Fast Edge Detection Using Structured Forests

1 B-404,Neelsidhi Atlantis, PIIT, Navi Mumbai, India 2 Sector 19A,Nerul, New Panvel, Navi Mumbai, India Email: bindu_k_nair@hotmail.com, ujwal.harode@gmail.com ABSTRACT An important and very crucial component of many systems involving images is the edge detection which includes object detectors and image segmentation algorithms. Edge patches always shows shapes of its inherent structure, like T junctions or lines. Taking advantage of the shapes available in the images we get to know of an edge detector which is accurate and efficient. In this approach the structured labels is robustly mapped to a space that is discrete by which evaluation of the measure of the standard information gain is possible. The outcome is a way that shows a real time performance which is many times faster than any of the traditional and modern approaches available today, which also achieves the best results for edge detection both the Berkeley Segmentation Dataset and Benchmark (BSDS 500) and the NYU depth dataset. This approach also shows its strength as a an edge detector that can be used for any regular purpose by displaying how this method generalize across all datasets
The Detectability of Exo-Earths and Super-Earths Via Resonant Signatures in Exozodiacal Clouds

Directly imaging extrasolar terrestrial planets necessarily means contending with the astrophysical noise of exozodiacal dust and the resonant structures created by these planets in exozodiacal clouds. Using a custom-tailored hybrid symplectic integrator, we have constructed 120 models of resonant structures created by exo-Earths and super-Earths on circular orbits interacting with collisionless steady-state dust clouds around a Sun-like star. Our models include enough particles to overcome the limitations of previous simulations that were often dominated by a handful of long-lived particles, allowing us to quantitatively study the contrast of the resulting ring structures. We found that in the case of a planet on a circular orbit, for a given star and dust source distribution, the morphology and contrast of the resonant structures depend on only two parameters: planet mass and ap1/2/β , where ap is the planet’s semimajor axis and β is the ratio of radiation pressure force to gravitational force on a grain. We constructed multiparticle-sized models of 25,000 particles each and showed that in a collisionless cloud, a Dohnanyi crushing law yields a resonant ring whose optical depth is dominated by the largest grains in the distribution, not the smallest. We used these models to estimate the mass of the lowest mass planet that can be detected through observations of a resonant ring for a variety of assumptions about the dust cloud and the planet’s orbit. Our simulations suggest that planets with mass as small as a few times Mar’s mass may produce detectable signatures in debris disks at ap≳ 10 AU.
Microbial Community Profiling of Active Oleophilic Bacteria involved in Bioreactor-based Crude-oil Polluted Sediment Treatment

Petroleum hydrocarbon pollution has been a major environmental challenge in the coastal areas, Niger-Delta, Nigeria. In this study, culture dependent and molecular techniques were used to monitor bioremediation over a-64 day period in seven microcosms setup in 2.5 L stirred tank bioreactors with each tank containing either Poultry droppings (BPOUT), NPK fertilizer (BNPK), Cow dung (BCD) or Urea fertilizer (BUREA). One bioreactor (BAUG) was bioaugmented while two others served as unamended (BUNa) and heat-killed (BHKD) controls. A decrease in petroleum hydrocarbon concentration and a concomitant increase in biomass was observed in all treatments at varying levels. BNPK (97.2%; 97.1%) showed highest reduction percentage while BHKD (82.34%, 81.3%) was the least for total petroleum hydrocarbon and polycyclic aromatic hydrocarbon amongst all treatment. Screening of isolates for aromatic hydrocarbon ring cleavage functional gene (catechol 2,3-dioxygenase) revealed that catechol 2,3-dioxygenase (C23D0) gene was detected in the following genera: Pseudomonas spp. (3), Rhodococcus sp. (2), Bacillus spp. (2). , Achromobacter sp. , Serratia sp. , Aeromonas sp. , Micrococcus sp. and Acinetobacter sp. Sequences obtained from amplification of 16S rRNA gene gave a total number of 24 hydrocarbon utilizing bacterial species which showed 96-100% similarity with those deposited in GenBank and are identified as Brevundimonas naejangsanensis, Pseudomonas pseudoalcaligenes, Pseudomonas spp. (6), Aquitalea magnusonii, Achromobacter sp. , Halomonas lutea, Pseudomonas aeruginosa (8), Shewanella sp, Achromobacter sp. , Gordonia sp. , Sphingobacterium sp. and Bacillus sp. Our result revealed that these extant indigenous bacterial population in the crude oil-polluted sediment habour the relevant aromatic hydrocarbon ring cleavage genes (catechol 2,3-dioxygenase) and may have a key role in bioremediation of crude oil-polluted sediment.
Advertising Content and Consumer Engagement on Social Media: Evidence from Facebook

We describe the effect of social media advertising content on customer engagement using data from Facebook. We content-code 106,316 Facebook messages across 782 companies, using a combination of Amazon Mechanical Turk and natural language processing algorithms. We use this data set to study the association of various kinds of social media marketing content with user engagement—defined as Likes, comments, shares, and click-throughs—with the messages. We find that inclusion of widely used content related to brand personality—like humor and emotion—is associated with higher levels of consumer engagement (Likes, comments, shares) with a message. We find that directly informative content—like mentions of price and deals—is associated with lower levels of engagement when included in messages in isolation, but higher engagement levels when provided in combination with brand personality–related attributes. Also, certain directly informative content, such as deals and promotions, drive consumers’ path to conversio.
The Challenges of Balancing Careers and Family Life Facing College Women in Jordan

The Challenges of Balancing Careers Family Life Facing College Women in Jordan Anna Chang ISP CODES: Gender Studies, 507 Regional Studies: Middle East, 521 Sociology: 528 The country of Jordan serves as one of the most progressive countries in the Middle East, yet Jordan has the lowest female economic participation rates out of all the countries in the Middle East and North Africa (MENA) region. Quantitatively, women’s higher education attainment equals and, in some cases, even surpasses that of men. However, their economic participation barely begins to compare to that of their male counterparts. The purpose of this study is to investigate the potential causes for this large gap, using qualitative evidence from the interviews of fifteen college women at the University of Jordan and regional and national statistics and indicators. By analyzing women’s plans, or lack thereof, for the future, the study hopes to provide Jordanian college women with a chance to share their ideas on gender equality, ideal family dynamics, and pressures from society. By investigating the research question of, “What are the challenges college women believe they will face when trying to balance pursuing a career and fulfilling the demands of a family? ” the findings led to a conclusion in support of the original hypothesis. Women who have yet to attempt to juggle professional goals with family demands underestimate the challenges they will face and thus also fail to address these concerns

Intervention of Iron-folic Acid in School children

Abstract Iron and folate deficiency is an important cause of anaemia among young children. Folate is necessary for the production and maintenance of new cells. This is especially important during periods of rapid cell division and growth such as infancy and pregnancy. The aim of this study was to estimate the magnitude of iron deficiency and the improvement in the Hb level by alternate day IFA supplementation. It was observed that amongst 65 students, 63% were found to be anaemic. After alternate day IFA supplementation for 1 month the prevalence decreased to 48.4% with overall increase in mean Hb of 0.59 gm%, from 11.29 to 11.88.
Dyslipidemia among Patients with End Stage Renal Disease on Maintenance Hemodialysis

Dyslipidemia has been suggested to be one of the factors that contribute to the high incidence of cardiovascular disease in hemodialysis patients. Previous studies suggest that end-stage renal disease may contribute to dyslipidemia. The aim of the study: to assess the prevalence of dyslipidemia in patients on maintenance hemodialysis. Patients and Methods: A case-control study was conducted from February 2015 until August 2015 in Ibn-Sena teaching hospital on 100 participants (52 males and 48 females), 50 were patients with end-stage renal disease on regular hemodialysis and 50 were age and gender-matched apparently healthy subjects as the control. Questioner used to collect data, a thorough examination was done including height and weight and BMI. A blood sample from all participants in fasting state was sent for the renal function test, complete blood picture, serum albumin, electrolytes, TG, total cholesterol, LDL and HDL measured by the enzymatic method, plasma atherogenic index calculated as [log (TG/HDL)]. Results: Age of the participants ranged between 18 - 70 years and the mean age was (44.45 ± 13.6) years. In HD group, the mean cholesterol was (3.29 + 0.73) mmol/l, serum TG (2.38 ± 0.56) mmol/l, LDL (1.91 ± 0.66) mmol/l, HDL (0.88 ± 0.2) mmol/l, atherogenic index (0.434 ± 0.16), while in control group, the mean cholesterol was (4.17 ± 0.69) mmol/l, serum TG (1.6 ± 0.43) mmol/l, LDL (2.69 ± 0.63 ) mmol/l, HDL (1.066 ± 0.13) mmol/l, atherogenic index (0.177 ± 0.12). The lipid abnormalities in hemodialysis group were high plasma atherogenic index in 84%, hypertriglyceridemia 50%, hypercholesterolemia 8% and high LDL 6% and low HDL in 48%, while in control group, high plasma atherogenic index in 34%, hypertriglyceridemia in 26%, hypercholesterolemia 14% high LDL 7% and low HDL in 16%. Conclusions: patients with end-stage renal disease on hemodialysis have significant dyslipidemia compared to control group characterized by hypertriglyceridemia, low HDL and high atherogenic index of plasma.
Cross-Sectoral Coordination of Disaster Relief

Abstract Coordinating organizational activity across different sectors is crucial in disaster management. We analysed the response of 291 aid workers to the Haiti earthquake in 2010 and found that common incentives and a high degree of equality among aid organizations positively affected perceived network coordination. Large and public organizations were more likely to take leadership roles and high numbers of public organizations involved in the disaster response network led to improved network coordination. These results indicate the need for mechanisms that enable smaller and non-profit organizations to participate in network coordination and leadership.
Circumnuclear Structures in the Interacting Seyfert Galaxy NGC 1241: Kinematics and Optical/Infrared Morphology

We studied the spiral pattern in the inner 6. ″5 (1′′ = 257 pc) central regions of the interacting active nucleus galaxy NGC 1241 using Gemini North Telescope high-resolution Ks- and J-band images and Hubble Space Telescope (HST) Paα and H- and (V + R)-band images with high resolution in the range from ~0. ″1 to ~0. ″3 along with intermediate to large-scale spectroscopy using the Multifunction Spectrograph at the Córdoba Observatory in Argentina. Our analysis of Paα emission images revealed a faint two-armed leading spiral pattern ending in the 5. ″6 × 3. ″4 clumpy ring discovered by Böker and coworkers, harboring a 1. ″6 long barlike structure almost perpendicular to the large-scale bar of NGC 1241. When we applied two-dimensional Fourier analysis at circumnuclear scales, we found that a two-arm trailing mode was dominant in Ks- and J-band images while the (V + R)-band images showed more complex structural features with a strong one-armed trailing mode. One-dimensional Fourier analysis showed a corotation (CR) located outward from the edge of the Paα bar. Our kinematics data gave an angular speed ΩCN of 350 ± 50 km s-1 kpc-1 for the trailing mode pattern. The rotation curve showed that the circumnuclear ring is located just inside the large-scale pattern inner Lindblad resonance (ILR), which has a radius of about r ~ 1 kpc. We also found, within the uncertainties present in such measurements, that the outer Lindblad resonance (OLR) of the circumnuclear pattern is coincident with the large-scale pattern ILR, indicating a possible connection between circumnuclear and global dynamics. Nevertheless, the estimated high molecular gas fraction (≥13%) and the inner pattern high angular speed at the central region of NGC 1241 point to a nuclear bar formation via self-gravitational instability.
Real-time 3D Face-Eye Performance Capture of a Person Wearing VR Headset

Teleconference or telepresence based on virtual reality (VR) head-mount display (HMD) device is a very interesting and promising application since HMD can provide immersive feelings for users. However, in order to facilitate face-to-face communications for HMD users, real-time 3D facial performance capture of a person wearing HMD is needed, which is a very challenging task due to the large occlusion caused by HMD. The existing limited solutions are very complex either in setting or in approach as well as lacking the performance capture of 3D eye gaze movement. In this paper, we propose a convolutional neural network (CNN) based solution for real-time 3D face-eye performance capture of HMD users without complex modification to devices. To address the issue of lacking training data, we generate massive pairs of HMD face-label dataset by data synthesis as well as collecting VR-IR eye dataset from multiple subjects. Then, we train a dense-fitting network for facial region and an eye gaze network to regress 3D eye model parameters. Extensive experimental results demonstrate that our system can efficiently and effectively produce in real time a vivid personalized 3D avatar with the correct identity, pose, expression and eye motion corresponding to the HMD user.
DEPARTMENTAL EFFECTS ON SCIENTIFIC PRODUCTIVITY

Productive scientists tend to hold jobs at prestigious university departments, but it is unclear whether this is because good departments hire the best scientists or because good departments encourage and facilitate research productivity. To resolve this issue, we studied the antecedents and consequences of 179 job changes by chemists, biologists, physicists, and mathematicians. Those who were upwardly mobile showed substantial increases in their rate of publication and in the rate of citation to those publications, while those who were downwardly mobile showed substantial decreases in productivity. Earlier analyses of these job changes found only a small effect of prior productivity on destination prestige. These results suggest that the effect of department affiliation on productivity is more important than the effect of productivity on departmental affiliation.
Climate-carbon cycle feedbacks under stabilization: uncertainty and observational constraints

Avoiding ‘dangerous climate change’ by stabilization of atmospheric CO2 concentrations at a desired level requires reducing the rate of anthropogenic carbon emissions so that they are balanced by uptake of carbon by the natural terrestrial and oceanic carbon cycles. Previous calculations of profiles of emissions which lead to stabilized CO2 levels have assumed no impact of climate change on this natural carbon uptake. However, future climate change effects on the land carbon cycle are predicted to reduce its ability to act as a sink for anthropogenic carbon emissions and so quantification of this feedback is required to determine future permissible emissions. Here, we assess the impact of the climate-carbon cycle feedback and attempt to quantify its uncertainty due to both within-model parameter uncertainty and between-model structural uncertainty. We assess the use of observational constraints to reduce uncertainty in the future permissible emissions for climate stabilization and find that all realistic carbon cycle feedbacks consistent with the observational record give permissible emissions significantly less than previously assumed. However, the observational record proves to be insufficient to tightly constrain carbon cycle processes or future feedback strength with implications for climate-carbon cycle model evaluation.
Volatile cycling of H2O, CO2, F, and Cl in the HIMU mantle: A new window provided by melt inclusions from oceanic hot spot lavas at Mangaia, Cook Islands

Mangaia hosts the most radiogenic Pb‐isotopic compositions observed in ocean island basalts and represents the HIMU (high µ = 238U/204Pb) mantle end‐member, thought to result from recycled oceanic crust. Complete geochemical characterization of the HIMU mantle end‐member has been inhibited due to a lack of deep submarine glass samples from HIMU localities. We homogenized olivine‐hosted melt inclusions separated from Mangaia lavas and the resulting glassy inclusions made possible the first volatile abundances to be obtained from the HIMU mantle end‐member. We also report major and trace element abundances and Pb‐isotopic ratios on the inclusions, which have HIMU isotopic fingerprints. We evaluate the samples for processes that could modify the volatile and trace element abundances postmantle melting, including diffusive Fe and H2O loss, degassing, and assimilation. H2O/Ce ratios vary from 119 to 245 in the most pristine Mangaia inclusions; excluding an inclusion that shows evidence for assimilation, the primary magmatic H2O/Ce ratios vary up to ∼200, and are consistent with significant dehydration of oceanic crust during subduction and long‐term storage in the mantle. CO2 concentrations range up to 2346 ppm CO2 in the inclusions. Relatively high CO2 in the inclusions, combined with previous observations of carbonate blebs in other Mangaia melt inclusions, highlight the importance of CO2 for the generation of the HIMU mantle. F/Nd ratios in the inclusions (30 ± 9; 2σ standard deviation) are higher than the canonical ratio observed in oceanic lavas, and Cl/K ratios (0.079 ± 0.028) fall in the range of pristine mantle (0.02–0.08).
