Social determinants of health—Street children at crossroads  [PDF]
Anjali Gupta
Health (Health) , 2012, DOI: 10.4236/health.2012.49100
Abstract: 1The term “street children” has been used inter changeably with “children in especially difficult circumstances” in the remaining document. This paper discusses the findings of a research project which is an exploratory cum descriptive study [1] that aims to describe and examine the state and nature of the quality of life of street children accommodated at an unorganised colony in the city of Delhi. It provides a social profile of children and their families, and exploring the needs and aspirations of these children living in especially difficult circumstances. A non-probability sample of 100 street children in the age group of 5-16 years was randomly selected guided by their availability. An interview schedule was constructed and administered to gather data. The statistical analyses comprised frequencies and percentages on all the sections of the interview schedule. Thematic content analysis was used to analyse data from open-ended questions and observations. Case studies were supportive in giving an insight into the lives of children living in especially difficult circumstances. Findings suggest that the quality of life of the participants in this study was depressed due to a lack of access or substandard educational and medical facilities, or absence of emotional support from their poverty stricken families. The existing limited programmes by the government or the civil society for the welfare of street children are lacking in their focus and do not include the voices and needs of the beneficiaries. Although service providers expressed sympathy for street children, many regarded them as deviants, delinquents, future criminals, and a public nuisance. Based on the findings, it has been suggested that the street child phenomenon necessitates a partnership between governmental and non-governmental organizations to provide for policy and legislation, funding and resources to translate programs into concrete plans of action. It has further been argued that such an approach should extend to children using their resourcefulness and creativity, and show that they can be significant in development interventions. Children illustrate both the need for participatory approaches and the problems that arise when perceptions of participants conflict with those of experts.
Ectopic Autosomal Dominant Polycystic Kidney Disease (ADPKD)—An Extremely Rare Radiological Finding  [PDF]
Manish Gupta
Open Journal of Radiology (OJRad) , 2014, DOI: 10.4236/ojrad.2014.41015

ADPKD is an inherited systemic disorder that predominantly affects the kidney, but may affect other organs including liver, pancreas, brain, and arterial blood vessel. APKPD occurs worldwide affecting about 1 in 500 - 1000 people. Hypertension is the most common manifestation of ADPKD and the major contributor to renal disease progression. A definite diagnosis of ADPKD relies on image testing. Renal ultrasound is commonly used because of its cost effectiveness.

A Rare Case of Acute Cerebrovascular Accident in the Post-Partum Period after Primary Angioplasty during Pregnancy  [PDF]
Ruchi Gupta
International Journal of Clinical Medicine (IJCM) , 2015, DOI: 10.4236/ijcm.2015.612118
Abstract: Pregnancy-related acute myocardial infarction is rare, but a serious event. We report a case of acute myocardial infarction in a 33-year-old female with 5 months of pregnancy. Angiography, under abdominal shield, revealed 100% thrombotic occlusion in the left anterior descending artery, which was treated successfully with a stent implantation. The patient was found to have hyperhomocysteinemia within the first week of primary percutaneous coronary intervention (PCI). Rest of the follow-up was uneventful with delivery of a healthy baby by elective caesarean section at about 36 weeks of gestation. Within 7 days of post-partum period, the patient displayed signs of cerebrovascular infarction and was managed successfully. To the best of our knowledge, the association between primary PCI during pregnancy and cerebrovascular event in the postpartum period has not been reported previously.
New Single Input Multiple Output Type Current Mode Biquad Filter Using OTAs  [PDF]
Manish Gupta
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.74022
Abstract: This paper presents a new current mode (CM) single-input and multi-output (SIMO)-type biquad using two multiple output OTAs and one current follower as an active device and having two grounded capacitors. This SIMO type circuit realizes all the five filter functions as low pass, band pass, high pass, band reject and all pass filter transfer functions simultaneously. This circuit has the unity gain transfer function for all the five types of filters. The circuit enjoys electronic tunability of angular frequency and bandwidth. The 0.18 μm TSMC technology process parameters have been utilized to test and verify the performance characteristics of the circuit using PSPICE. The sensitivity analysis, transient response and calculations of total harmonic distortion have also been shown.
A Review of Corporate Hedging Models and Their Relevance in Corporate Finance  [PDF]
Pankaj Gupta
Theoretical Economics Letters (TEL) , 2017, DOI: 10.4236/tel.2017.72010
Abstract: In this paper, a review of theoretical literature of models providing rational of corporate hedging is done and also addresses the corporate finance issues such as financing and investment. As per definition, hedging is either an insurance contract or an activity reducing the correlation between value and random variable linked with the derivative purchase. It is found that, when considering the modern finance theory after relaxing the assumptions made by Modigliani & Miller, the corporate hedging reduces several costs such as agency cost, distress cost and cost of debt. Also, hedging models are explained reducing the adverse selection problem. An integrated approach based models are also present in the review.
A Survival Approach to Prediction of Default Drivers for Indian Listed Companies  [PDF]
Vandana Gupta
Theoretical Economics Letters (TEL) , 2017, DOI: 10.4236/tel.2017.72011
Abstract: The objective of the research study is to identify the key predictors that can explain default risk for Indian listed companies using survival analysis. The author has applied the semi-parametric Cox proportional hazard model to test the impact of financial ratios, capital market ratios, macro-economic variables, size and age of companies, and the ownership structure of promoters to a dataset of 859 companies panning across 10 sectors. Unlike traditional models on default prediction, survival models focus on time to default as the dependent variable. The empirical findings reveal that return on capital employed (ROCE), return on net worth (ROE), interest coverage ratio, exchange rate volatility, GDP growth rate, stock index, promoters holdings % and the percent of shares pledged are all significant predictors of default. Among the market variables, it is seen that beta and the ratio of market value of equity/book value of debt are statistically significant variables in explaining default risk. The empirical findings also generate the hazard ratio for each covariate which examines the predicted change in the hazard for a unit increase in the predictor. The author extends the research by applying the market-based KMV structural model to obtain continuous observations of default probability and regressing the same against all the?covariates (Gupta et al.,
Smartphone Based Cervical Spine Stress Prevention  [PDF]
Harsh Gupta
Journal of Software Engineering and Applications (JSEA) , 2018, DOI: 10.4236/jsea.2018.112006
Abstract: Rapidly increasing smartphone usage has resulted in an increasingly adverse impact on the health of people. Cervical Spine Stress and the risk of Thoracic Kyphosis have been accentuated due to inappropriate posture. Existing efforts to solve this problem require the use of expensive wearable devices or can only be implemented on selected smartphones. This paper has proposed a novel posture detecting mechanism which does not require any external devices and can be implemented inexpensively on all smartphones. The solution has utilized the built-in 3-dimensional accelerometer of the smartphone and provided an Android Operating System-based application as a proof of concept that determines the Cervical Spine posture and generates ALERTS when necessary. In addition, data of the posture could be displayed in form of graphs to make the user aware of his or her posture trend throughout the week. The application can be extended to different operating systems.
Open Market Repurchases and Signaling Hypothesis  [PDF]
Vandana Gupta
Theoretical Economics Letters (TEL) , 2018, DOI: 10.4236/tel.2018.83041
Abstract: This paper analyzes the impact of open market repurchase (OMR) route of buyback on the stock prices of a data set of 30 Indian listed firms which had gone for buyback in the FY16. The author has applied event study methodology to calculate abnormal returns and cumulative abnormal returns on stocks using BSE 500 as market index. The returns are calculated for 20 days prior and post buyback announcement to test for information signaling hypothesis. The analysis shows that average abnormal return (AAR) on the date of announcement is -0.23 percent while cumulative abnormal return (CAR) is about 5.72 percent on the announcement date with an overall CAR 3.44 percent for 40-day event window. The research findings reveal that unlike tender offers, OMR does not lead to a signaling effect as there is the insignificant impact on stock prices. Market reaction to buyback offer is in contradiction to signaling hypothesis predictions. The results of the study imply that the information related to the announcement of the buyback is already reflected in the share price. This also throws light on the growing maturity and efficiency of the stock market of India. Analyzing the signaling effect through OMR reveals that rather than signaling hypothesis, market reaction to buybacks is better explained by free cash flow hypothesis.
Predicting Accuracy of Valuation Multiples Using Value Drivers: Evidence from Indian Listed Firms  [PDF]
Vandana Gupta
Theoretical Economics Letters (TEL) , 2018, DOI: 10.4236/tel.2018.85052
Abstract: The objective of this research study is twofold: 1) to evaluate the prediction accuracy of four valuation multiples across three sectors for Indian listed firms and 2) to identify the fundamental drivers for these multiples. The valuation multiples identified for this study are: price to earnings (P/E), price to book value (P/BV), price to sales (P/S) and enterprise value to earnings before interest, depreciation, tax and amortization (EV/EBIDTA) and the sectors taken are steel, banking and automobile. Multiple regression methodology is followed with the valuation multiple as dependent variable and the value drivers as independent variables, to get predicted multiples on 470 firm observations. By regressing the multiples on fundamental variables, the best suited multiple for each sector and the key drivers of the multiple are obtained. The empirical findings based on root mean square error (RMSE) and Theil coefficient reveal that least prediction errors are observed in P/S and EV/EBIDTA for the automobile sector, EV/EBIDTA for the steel sector and P/BV for the banking sector. It is also observed that the significant variables that explain these multiples are beta, return on equity (ROE), return on capital employed (ROC), dividend payout ratio (D/P) and net profit margins (NPM). These findings are in line with the derivation of fundamental drivers for each multiple as explained in Gordon model. Damodaran: 2007 [1]. The present work contributes to emerging market literature on equity valuations and attempts to compare valuations based on market approach using value drivers. A comparison of forecasts with actuals helps in recommendations to buy/sell/accumulate/hold for equity investors and is also pertinent for market participants and financial regulators.
