The Impact of Macroeconomic Indicators on Indian Stock Prices: An Empirical Analysis
Authors: Giri A. K. , Joshi Pooja 
Published: June 2017

Abstract
The purpose of the present study is to examine the long run and the short run relationship between stock price and a set of macroeconomic variables for Indian economy using annual data from 1979 to 2014. The long run relationship is examined by implementing the ARDL bounds testing approach to co-integration. VECM method is used to test the short and long run causality and variance decomposition is used to predict long run exogenous shocks of the variables. The results confirm a long run relationship among the variables. Evidence suggests that Economic growth, inflation and exchange rate influence stock prices positively. However, crude oil price influences the stock price negatively. This implies that the increase in oil price induces inflationary expectation in the mind of investors and hence stock prices are adversely affected. The VECM result indicates that short run and long run unidirectional causality running from economic growth and FDI to stock prices in India. The result of the variance decomposition shows that stock market development in India is mostly explained by its own shocks. The Government can take steps to control the crude oil price in India and Investors’ confidence has to be gained by boosting the economic growth of the economy through appropriate policy tools.

Authors: Herciu Mihaela 
Published: June 2017

Abstract
The main purpose of this paper is to identify the drivers of firm performance by exploring both quantitative indicators - based on accounting profitability, shareholder value and economic value – and qualitative approach – based on balanced scorecard and triple bottom line. A literature review will be provided in order to obtain an optimum mix of quantitative and qualitative drivers for firm performance, on one hand, and a case study will be conducted for emphasizing the importance of both approaches, on the other hand.

Published: June 2017

Abstract
This paper aims at investigating the link between fraud and business cycle in Nigeria using primary data sourced from questionnaires administered on both fraudsters and fraud managers. This is premised on the ground that Nigeria is in recession and has been recently described as fantastically corrupt. Understanding the link between fraud and economic behaviour would give an in depth understanding of fraud levels in the different phases of the Nigerian economy and would help the fraud management system in Nigeria which is believed to have great consequences on the nation's economy. Our result shows that though there is a significant relationship between fraud and business cycle in Nigeria, the level of fraud committed does not solely depend on either expansion or recession exists in the economy, rather, there is an identified range of fraud that might be increased in adverse economy.
Investigating a Random Walk in Air Cargo Exports of Fresh Agricultural Products: Evidence from a Developing Country
Authors: Mawanga Freddie Festo 
Published: June 2017

Abstract
Since the 1990s exports of fresh agricultural products by air from Uganda have been increasing and making a significant contribution to her International trade. Products include mostly fish, flowers, papain, and vanilla constituting over 95% of all air exports. Farming of the items is mainly by small scale farmers who depend on the natural climate of the country. Consequently, monthly yields are also climate dependent making individual export volumes unpredictable. In spite of these uncertainties, this study was intended to investigate possible existence of a model in the trends. Monthly data were collected from Uganda Civil Aviation Authority from 2009 to 2012. Analysis was by using ARIMA Approach with the help of Eviews 8. Visually the data exhibited irregular patterns and without a trend or seasonality. First order differencing stationarised the data and the residuals had a random non-significant noise suggesting a Random Walk Model expressed as ARIMA (0, 1, 0) and a negative drift. The model shows a link between current and one lag export volumes and the negative drift is a convergence of successive differences in export volumes. These findings have policy implications in expansion and forecasting of the exports potential of applicability of Random Walk Theory in practice.
Nonlocal Symmetries, Consistent Riccati Expansion, and Analytical Solutions of the Variant Boussinesq System
Authors: Feng Lian-Li , Tian Shou-Fu , Zhang Tian-Tian , Zhou Jun 
Published: June 2017

AbstractUnder investigation in this paper is the variant Boussinesq system, which describes the propagation of surface long wave towards two directions in a certain deep trough. With the help of the truncated Painlevé expansion, we construct its nonlocal symmetry, Bäcklund transformation, and Schwarzian form, respectively. The nonlocal symmetries can be localised to provide the corresponding nonlocal group, and finite symmetry transformations and similarity reductions are computed. Furthermore, we verify that the variant Boussinesq system is solvable via the consistent Riccati expansion (CRE). By considering the consistent tan-function expansion (CTE), which is a special form of CRE, the interaction solutions between soliton and cnoidal periodic wave are explicitly studied.
Highly Accurate Analytical Approximate Solution to a Nonlinear Pseudo-Oscillator
Authors: Wu Baisheng , Liu Weijia , Lim C.W. 
Published: June 2017

Abstract
A second-order Newton method is presented to construct analytical approximate solutions to a nonlinear pseudo-oscillator in which the restoring force is inversely proportional to the dependent variable. The nonlinear equation is first expressed in a specific form, and it is then solved in two steps, a predictor and a corrector step. In each step, the harmonic balance method is used in an appropriate manner to obtain a set of linear algebraic equations. With only one simple second-order Newton iteration step, a short, explicit, and highly accurate analytical approximate solution can be derived. The approximate solutions are valid for all amplitudes of the pseudo-oscillator. Furthermore, the method incorporates second-order Taylor expansion in a natural way, and it is of significant faster convergence rate.

Published: June 2017

AbstractSerum amyloid A1 (SAA1) is an apolipoprotein that binds to the high‐density lipoprotein (HDL) fraction of the serum and constitutes the fibril precursor protein in systemic AA amyloidosis. We here show that HDL binding blocks fibril formation from soluble SAA1 protein, whereas internalization into mononuclear phagocytes leads to the formation of amyloid. SAA1 aggregation in the cell model disturbs the integrity of vesicular membranes and leads to lysosomal leakage and apoptotic death. The formed amyloid becomes deposited outside the cell where it can seed the fibrillation of extracellular SAA1. Our data imply that cells are transiently required in the amyloidogenic cascade and promote the initial nucleation of the deposits. This mechanism reconciles previous evidence for the extracellular location of deposits and amyloid precursor protein with observations the cells are crucial for the formation of amyloid.

AbstractThe nuclear ribosomal DNA (rDNA) is considered as a paradigm of concerted evolution. Components of the rDNA tandem repeats (45S) are widely used in phylogenetic studies of different organisms and the internal transcribed spacer (ITS) region was recently selected as a fungal DNA bar code. However, rRNA pseudogenes, as one kind of escape from concerted evolution, were reported in a wide range of organisms, especially in plants and animals. Moreover, large numbers of 5S rRNA pseudogenes were identified in several filamentous ascomycetes. To study whether rDNA evolves in a strict concerted manner and test whether rRNA pseudogenes exist in more species of ascomycetes, intragenomic rDNA polymorphisms were analyzed using whole genome sequences. Divergent rDNA paralogs were found to coexist within a single genome in seven filamentous ascomycetes examined. A great number of paralogs were identified as pseudogenes according to the mutation and secondary structure analyses. Phylogenetic analyses of the three rRNA coding regions of the 45S rDNA repeats, i.e., 18S, 5.8S, and 28S, revealed an interspecies clustering pattern of those different rDNA paralogs. The identified rRNA pseudogenic sequences were validated using specific primers designed. Mutation analyses revealed that the repeat-induced point (RIP) mutation was probably responsible for the formation of those rRNA pseudogenes.

AbstractHow do cells ensure everything is set for cell division before they start the process? Piccirillo et al. demonstrate that a checkpoint in budding....The Rlm1 transcription factor is a target of the cell wall integrity pathway. We report that an rlm1Δ mutant grown on a nonfermentable carbon source at low osmolarity forms cell groups in which a mother cell is surrounded by smaller “satellite-daughter” cells. Mother cells in these groups progressed through repeated rounds of cell division with normal rates of bud growth and genetic stability; however, these cells underwent precocious START relative to wild-type mothers. Thus, once activated, Rlm1 delays the transition from G1 to S, a mechanism we term the cell wall/START (CW/START) checkpoint. The rlm1Δ satellite-cell phenotype is suppressed by deletion of either SLT2, which encodes the kinase that activates Rlm1, or SWI4, which is also activated by Slt2; suggesting that Slt2 can have opposing roles in regulating the START transition. Consistent with an Rlm1-dependent CW/START checkpoint, rlm1Δ satellite daughters were unable to grow or divide further even after transfer to rich medium, but UV irradiation in G1 could partially rescue rlm1Δ satellite daughters in the next division. Indeed, after cytokinesis, these satellite daughters shrank rapidly, displayed amorphous actin staining, and became more permeable. As a working hypothesis, we propose that duplication of an “actin-organizing center” in late G1 may be required both to progress through START and to reestablish the actin cytoskeleton in daughter cells.

Published: June 2017

Background: Abdominal pain is one of the most common reasons for visit to the emergency room. Acute appendicitis is the commonest cause. An accurate diagnosis is essential for the correct treatment, which in many cases will prevent the death of the patient. Mainstay of diagnosis is history and physical examination. If this information is inadequate to establish a diagnosis and urgent or immediate operation is unnecessary, the periodic re-examination helps document the progression of the disease and often avoids unnecessary surgical intervention. Today the combination of improved diagnostic procedures, antibiotic and better anaesthesia and preoperative and postoperative patient care has led to a decrease in morbidity and mortality of patients with acute abdomen. The objective of this study was to determine the various causes of non-traumatic acute abdominal emergencies, their incidence, management and mortality in both sexes and all age groups >12 years age.Methods: The Study was conducted on 1353 patients of non-traumatic abdominal emergencies admitted in the department of surgery, associated group of hospitals attached to Dr. Sampurnanand Medical College, Jodhpur over a period of 1 year extending from 1st January 2015 to 31st December 2015.Results: Most common cause of acute non-traumatic emergency in our study is acute appendicitis 61.71% of the patients. Out of 1353 cases of non-traumatic acute abdominal emergencies, 217 (16%) were managed conservatively while 1136 (84%) were operated. 96.64% cases of acute appendicitis were operated and only 3.36% underwent conservative management. The rate of operative intervention in acute intestinal obstruction and acute cholecystitis was 89.09% and 85.71% respectively. 81.89% cases of hollow viscus perforation were operated while 18.11% were treated conservatively. Only 18.18% cases of liver abscess underwent operation while all patients of Meckel's Diverculititis were managed operatively. All patients of acute pancreatitis were managed conservatively. Overall mortality in our study of acute non-traumatic abdominal emergencies was 3.39%.Conclusions: It can be concluded that acute non-abdominal emergencies admitted in the hospital constitute a major chunk of surgical patients, majority requiring operative management with limited mortality.

Published: June 2017

Background: The technique for intestinal anastomosis in elective gastrointestinal surgeries depends on site, bowel calibre and underlying disease. The decision to choose hand sewn or stapler anastomosis depends on surgical experience and preference. The objective of this study was to study the outcome of hand sewn anastomosis compared with stapler anastomosis in elective gastrointestinal surgeries.Methods: Retrospective comparative study was conducted in surgical wards of a tertiary referral hospital from July’2013 to June’2016. Data analysed with independent samples T-test to compare mean values between methods and Chi-square tests used to compare proportion of the two values.Results: Significant difference in duration of procedure, return of bowel sounds, starting of oral feeds, hospitalization days, return to work noted in stapler anastomosis compared with hand sewn anastomosis in subtotal gastrectomy and gastrojejunostomy. No difference in appearance of bowel sounds in right hemicolectomy and other resection and anastomoses group, no difference in return to work in right hemicolectomy group, no difference in starting of oral feeds in low anterior resection group. Other parameters were statistically significant in right hemicolectomy, low anterior resection and other resection and anastomosis groups. No significant difference observed in anastomotic leak between hand sewn and stapler methods. There was no mortality in stapler group.Conclusions: Stapler method significantly reduces duration of surgery, has early recovery with less mortality. Stapling is quick to perform in inaccessible situations like low colorectal anastomosis. Stapler anastomosis can be used safely and effectively in elective gastrointestinal surgeries.

Published: June 2017

Background: Inguinal hernia repair is one of the most frequently performed operations in general surgery worldwide. Routinely used gold standard Lichtenstein technique gives a long scar and more post-operative pain. TEP has demonstrated favourable short-term results, with regards to reduced postoperative stay, pain and earlier return to physical activity in comparison with open mesh repairs.Methods: This study was prospective observational study in which 75 patients were included for TEP repair and followed for the outcome measured as the time taken for operation, incidence of intra operative and post-operative complications, severity of pain at post-operative day 1, 1 week, 1 month and 6 months after operation, return to work and cost effectiveness of inguinal hernia repair.Results: We have enrolled the 75 patients from 16 to 80 years out of which 34 (45.3%) patients were from age group 50 to 70 years. 47 (62.7%) patients operated on right side and 58 (77.4%) were operated for indirect hernia. Mean time taken for TEP was 81.5 minutes with minimum of 45 minutes and maximum of 135 minutes. There was single most complications of Pneumoperitoneum in 24 (32.0%) which was benign and managed conservatively. Other complications include bleeding in 4 (5.3%) and vas injury in one (1.3%). the mean duration of time taken for return to work was 11 days. The mean cost of TEP was Rs. 5932 with minimum of Rs. 4327 and maximum of Rs. 7742.Conclusions: The laparoscopic (TEP) repair is well established surgery for primary hernia repair and the other open tension free Lichtenstein technique is still regarded as a gold standard for inguinal hernia repair. The laparoscopic hernia surgery attempting similar claims underwent controversies with conflicting results. Laparoscopic (TEP) inguinal hernia repair gives greater patient’s satisfaction and better cosmetic results than open (Lichtenstein) repair.

Published: June 2017

Background: As infection is a major cause of morbidity and mortality in neonates, early diagnosis and prompt treatment can prevent its serious consequences. The present study was conducted to determine the prevalence of infections in neonatal intensive care unit (NICU) of a tertiary care hospital and to study their risk factors, causative organisms and antimicrobial susceptibility pattern.Methods: Appropriate samples were collected from all neonates with clinical signs and symptoms of infections. Isolation of microorganisms, their identification and antimicrobial susceptibility was done according to standard microbiological techniques.Results: Among 1210 neonates admitted in the NICU, 393 (32.4%) were clinically suspected infections. The prevalence of Septicemia, Pneumonia, and Meningitis were 6%, 1.5%, 0.7% respectively. The predominant organisms causing neonatal infection were Gram negative bacteria followed by fungi and Gram positive bacteria. Among Gram negative bacteria, the antimicrobial resistance was highest for third generation Cephalosporins [Ceftazidime (81.1%), Cefotaxime (60.3%)]. In Gram positive bacteria highest resistance was observed for Penicillin and Ampicillin (91.3%). Methicillin resistance was observed in 91.6% of Coagulase negative Staphylococci (CoNS). All isolates of Candida parapsilosis were sensitive to Fluconazole, Voriconazole but resistant to Amphotericin B. Predominant risk factors were low birth weight (87.7%) and prematurity (75%). Maternal risk factors were pregnancy induced hypertension (13.4%) and premature rupture of membranes (PROM) (10.1%). The case fatality rate was 20.7%.Conclusions: There is a need of strict infection control measures and rational antibiotic policy to reduce the economic burden of hospital and community due to neonatal infections.
