Essays on the effects of past gains on subsequent risk-taking and stock returns

This study contributes to research on behavioral biases among individual investors by showing how investors increase their portfolio risk following favorable outcomes. Specifically, during portfolio rebalancing, when investors have realized positive returns after a period of negative market returns, they purchase stocks that increase portfolio volatility. The results suggest that investors attribute these returns to themselves, supporting a self-attribution bias. Consequently, investors gamble with their winnings over the next investment period. This behavior is consistent with the house money effect, previously not analyzed in the context of the stock market. Notably, inexperienced investors are especially prone to this effect.

Clipless Laparoscopic Cholecystectomy: An initial experience of 50 cases in Bangladesh

Background: Laparoscopic cholecystectomy (LC) is one of the most common general surgical procedure. Objective: The purpose of the present study was to observe the surgical outcomes of the patients after clipless laparoscopic cholecystectomy. Methodology: This case series were performed in the Department of Surgery at Shaheed Suhrawardy Medical College & Hospital, Dhaka from June 2014 to April 2015. After several modifications, the success of intracorporeal separate knotting of cystic artery and duct was observed with Vicryl and was successfully used separate ligation of cystic artery and duct (SLAD) with Vicryl 1/0 in symptomatic cholelithiasis patients. Result: A total number of 50 cases were undergone elective laparoscopic cholecystectomy. Most of the patients were female (80.0%). Average age of patients was 39 yr (15-65). There was no bile leak or other complications related to ligature. The time taken for tie varied from 2 to 4 minutes (average 3 min). There were 10(25.0%) acute calculus cholecystitis, including empyema, gangrenous cholecystitis. No patient had port infection. Conclusion: Clipless LC is a safe and effective method.

Essays on Trade and Growth

OF THE DISSERTATION ESSAYS ON TRADE AND GROWTH by Yulin Hou Florida International University, 2018 Miami, Florida Professor Cem Karayalcin, Co-Major Professor Professor Hakan Yilmazkuday, Co-Major Professor This dissertation is composed of three essays on international trade and economic growth. The first essay investigates whether the content of what economies export matters for human capital accumulation. I construct a small open economy model and find that expansion of primary exports can harm human capital accumulation if the economy is initially allocating significant resources to primary goods production. Then I test this prediction empirically using Latin American data over the period from 1965 to 2010 and find robust evidence in support of the hypothesis that a shift towards primary exports reduces human capital accumulation. In the second essay, I investigate the effects of gravity variables (distance, common border, colony relationship, free trade agreement, or language) on preference and trade costs. This essay models the imports of the U.S. at the individual good level and uses the three-stage least square regression approach by focusing on the trade elasticities. Using actual data on trade costs, this essay decomposes the overall effects of gravity variables on trade into those through gravity channels: duties/tariffs, transportation costs, and dyadic-preference. The results imply that gravity variables mainly capture the effect of preference rather than trade costs. In the final essay, I examine the effects of increased demand from China on economic growth of the Latin American and the Caribbean (LAC) countries. This essay
Clinical application on composite grafts of coral combined with autologous bone marrow reconstructing jaw defects

[Objective]To research the clinical effects on composite grafts of coral combined with autogous bone marrow being used to reconstruct jaw defects. Composite grafts of coral combined with autogous bone marrow were used to reconstruct 32 cases of jaw defects after neoplasm resection. The size of bone lesion ranged from 9.0 cm2 to 48.0 cm2,average 24.4cm2. Drawing 5～9 mL bone marrow from iliac crest ,put the coral into bone marrow and become composite coral, and then the composite coral was utilized to reconstruct jaw defects. The follow-up period was through 12 months to 8 years, average 4 years and 3 months. Osteogenesis was observed dynamically with radiography and scintigraphy postoperation. Of 32 cases, twenty-eight cases healed in one-stage, two cases healed in second-stage, and two cases failed because of infection. An increased radionuclide uptake began to be shown in the area of grafts at the 1st month. Coral resorption was observed at the 3rd month, and it was completely replaced by host newly bone at 9 to 24 months. [Conclusion] Composite coral graft may accelerate the repair of jaw defects, and it is a kind of excellent bone substitute to be elected.
PERFORMANCE EVALUATION OF ACTIVE CONTOUR MODELS FOR CAROTID PLAQUE SEGMENTATION

In this paper we compare four different snakes segmentation methods for segmenting the athrerosclerotic carotid plaque from longitudinal ultrasound images of the carotid artery. The accuracy and reproducibility of the methods were tested on 80 images and the results were compared with the manual delineations of an expert. The comparison showed that the Lai&Chin snakes segmentation method gave better results with the true positive fraction, TPF, true negative fraction TNF, Williams index, KI, and overlap index, to be 82.70%, 80.89%, 80.66%, and 69.30% respectively. Better false negative fraction, FNF, and false positive fraction, FPF, were given by the Balloon method with 13.90% and, 5.40% respectively.
Respiratory Health of Foundry Workers Exposed to Binding Resin

The effects of resin on the respiratory health have been investigated in 309 workers from four iron and steel foundries and the results compared with those from 122 workers who were not significantly exposed to resin gas and silica dust at the same industries. Phenol-formaldehyde resin was used in the core making and molding processes and workers were exposed to their decomposition products as well as to silica dust containing particulates. The subjects were grouped according to formaldehyde, dust and other gas exposures, and smoking habits were considered also in thi analysis. Standardized respiratory symptom questionnaire was administered by trained interviewers. Chest radiograph, pulmonary funtion tests, and methacholine challenge tests were done. Environmental measurements at the breathing zone were carried out to determine levels of formaldehyde, respiable dust and total dust. Foundry workers had a higher prevalence of symptoms of chronic bronchitis with chronic phlegm and chronic cough when exposed to dust. Exposure to gas was significantly associated with lowered and obstructive pulmonary function changes. Exposure to formaldehyde and phenol gas was associated with wheezing symptom among workers, but changes after methacholine challenge were not significantly different among different exposure groups. When asthma was defined as the presence of bronchial hyperreactivity with more than 20% decrease in after methacholine challenge, 17 workers out of 222 tested had asthma. Fewer asthmatic welters were found among groups exposed to formaldehyde, gas and dust, which indicates a healthy worker effects ill a cross-sectional study. The concentration of formaldehyde gas ranged from 0.24 to 0.43 ppm among studied foundries. The authors conclude that formaldehyde and phenol gas from combusted resin is probably the cause of asthmatic symptoms and also a selection force of those with higher bronchial reactivity away from exposures.
Technology humanness, trust and e-government adoption

With regards to technology adoption, users may be influenced by trust in two forms – human-like trust (e.g., benevolence, integrity, and ability) and system-like trust (e.g., helpfulness, reliability, and functionality). While the literature interestingly differentiates the use of these two types of trust, insufficient efforts have been devoted to examine and explain which type of trust should be used in the context of e-government. Additionally, when government agencies increasingly experience security breaches, insufficient literature examines how human-like trust and system-like trust may be influenced by such important antecedents as security threats and citizens’ security concerns in e-government settings. We propose a conceptual model to address this gap in the literature.
Homoeopathic management of Schizophrenia: A prospective, non-comparative, open-label observational study

Objectives: To evaluate the usefulness of homoeopathic intervention in Schizophrenia, in untreated cases and antipsychotic treatment resistant cases, to verify indications of medicines, and to assess relapse, if any. Materials and Methods: A prospective, non-comparative, open-label observational study was carried out from October 2005-September 2010 by CCRH at Central Research Institute (H), Kottayam, Kerala, India. Patients between 20 and 60 years of age, presenting with symptoms of Schizophrenia were screened for inclusion and exclusion criteria. The patients who were on antipsychotic drugs were allowed to continue the same along with homoeopathic medicine, the dose of antipsychotics was monitored by the Psychiatrist. The symptoms of each patient were repertorized, and medicine was initially prescribed in 30C potency after consulting Materia Medica. Patients were followed up for 12 months. Outcome of treatment was assessed with Brief Psychiatric Rating Scales (BPRS). Analysis was done using Statistical Package for the Social Sciences SPSS Version 20.0. Results: Out of 188 enrolled patients, 17 cases did not complete the baseline information. Total 171 patients were analysed as per modified Intention to Treat Principle. Significant difference (P = 0.0001, P < 0.05) in the mean scores of BPRS, using paired t test was observed at end of the study. Sulphur, Lycopodium, Natrum muriaticum, Pulsatilla and Phosphorus were found to be the most useful medicines in treating schizophrenic patients. Conclusion: The study reflects the positive role of homoeopathic medicines in the management of patients suffering from schizophrenia as measured by BPRS.
The Impact of Supervised Clinical Experience on Play Therapy Attitude, Knowledge and Skills

Supervision is a key component to the development of competent mental health counselors. Using a mixed methodology, we examined the impact of supervision on graduate students’ play therapy attitudes, knowledge, and skills. Quantitative data revealed statistically significant improvements. Qualitative data revealed that students perceived the supervision experience to be acceptable and effective. Limitations and implications for future studies are discussed.
Bacterial Profile and Antimicrobial Susceptibility Pattern of Surgical Site Infections – A Retrospective Study

Background: Surgical site infections (SSI) are one of the common causes of health care associated infections leading to increased morbidity among the post operative patients and a therapeutic challenge to the treating surgeon. Materials and methods: A retrospective study of post operative patients with SSI during a 6 month period was done based on the records.The bacteriological profile and antibiogram of isolates were analyzed. Results: The rate of S.S. I was5.1% and gram negative bacilli (GNB) were the more common pathogens 37/59 (62.7%), isolated with Esch.coli, constituting the highest 14/59 (23.7%). Imipenem was the most effective drug and ciprofloxacin was the least effective against Esch.coli. Conclusion: The incidence of SSI is rising due to the emergence of multidrug resistant bacteria. Rapid diagnosis of these pathogens will reduce the morbidity and mortality rate of SSI.
Disappointment Aversion and Long-Term Dynamic Asset Allocation

We examine the impact of return predictability and parameter uncertainty on investors' long-term portfolio allocations in the context of disappointment aversion. We find persisting horizon effects, with stocks appearing progressively more attractive at longer horizons as opposed to shorter ones. We find a level of disappointment aversion below which it is optimal for investors to hold zero units of a risky asset. Our analysis has implications for the nonparticipation puzzle in stock markets.
Heterogeneity and skill in the retail EUR/USD FX market : investigating the impact of uncertainty and behavioural biases of trader skills

One of the issues that has been debated in the literature is market heterogeneity. Traditional financial models adopt a popular assumption that markets are efficient and that participants act rationally such that their actions are homogeneous. Nevertheless, behavioural finance literature provides significant evidence of behavioural patterns and biases which render the assumption of homogeneity too simplistic and idealistic. Heterogeneity in financial markets can be defined as significant diversity in expectations of asset prices. I examine two aspects of heterogeneity in this thesis: trader’s performance and trader’s expectations. I also investigate whether traders possess genuine trading skills and how market volatility as well as a trader’s personal behavioural biases affect their skills. Using a dataset of more than twenty-one thousand retail FX traders on the EUR/USD market I find significant evidence of heterogeneity in performance and expectations, which persists throughout their trading career. I show that while around 68% of traders have the ability to correctly predict future price changes more than half of the time, only around 22.8% have the ability to generate overall positive returns. In addition, around 27% of traders have the ability to favourably adjust their position size based on the magnitude of the change in market prices. Moreover, I find that volatility has a detrimental impact on performance. Nevertheless, as this uncertainty becomes seasoned, individuals learn to understand it and adjust for it in their trading decisions. Finally, I find that skilled traders are herd initiators such that they are closely watched and copied by others. I also show that skilled traders exhibit the disposition effect, whereby they are more likely to realise small gains and hold on to large losses. In addition, skilled traders are also sensation seekers, indicating that they tend to use leverage to exploit price change; however, they tend to avoid extreme levels of leverage which can be detrimental to the performance and reputation. Skilled traders are more likely to be inconsistent in the amount of leverage and margin they use, which is explained by their ability to adjust their leverage ratio depending on the state of the market and their confidence in their trading decision. This thesis contributes to the literature on the micro dynamics of retail FX markets. My findings highlight that importance of understanding trader behaviour which provides insight into the decision-making process of individual traders and how these decisions are affected by endogenous behavioural factors as well as external market factors.
The Basel III Leverage Ratio: Unaffected by the Applied Risk Measurement Approach?

We examine the effects of the recently introduced regulatory leverage ratio, which aims to backstop existing risk-weighted capital requirements, on banks' balance sheets. We observe on average a deleveraging process, while banks simultaneously increase their risk-weighted assets. Having less regulatory leeway, banks applying the standardized approach are more inclined to raise capital in order to adjust the leverage ratio upwards. This implies that such banks become more stable as intended by policy makers. In contrast, the need to raise capital is significantly less pronounced for banks using internal models, which face more adjustment leeway when increasing their leverage ratio. Our findings suggest that imposing an unweighted leverage restriction does not necessarily alleviate the benefits from minimizing risk-weighted assets.
2011-04 Effective Tax and Subsidy Rates on Human Capital in Canada

Effective tax and subsidy rates (ETRs and ESRs) on human capital investment via postsecondary education are estimated for Canada in the years 2000 and 2006. The flattening of the federal personal income tax structure in 2001 substantially reduced the tax disincentive for investment in human capital. Effective subsidy rates also declined as public spending did not keep pace with rising tuition fees. The change on the tax side was strong enough to dominate the subsidy reduction according to our main results, but disaggregation shows that this result did not hold in all cases. Results are shown for College, Master’s, and PhD programs, in addition to Bachelor’s degrees. They are also broken down by gender, and are shown for the 25 and 75 percentiles as well as the median. Provincial detail and 1997 results are provided in the case of Bachelor’s graduates.
Frictions financières : théories et évidences

This thesis assesses the extent to which two types of nancial frictions contribute to the ability of New-Keynesian-type-stochastic dynamic general equilibrium models (DSGE) to reproduce business cycles and the ability of hybrid models (DSGE-VAR) to forecast macroeconomic aggregates. The rst type of nancial friction originates from a problem of Costly State Veri cation à la Bernanke et al. [1999] and appears in debt contracts. This type of friction implies a wedge between the expected return on capital and the risk-free rate that depends on entrepreneurial leverage, whereas the wedge is absent in models with no frictions. The second type of friction results from a problem of Costly Enforcement à la Gertler and Karadi [2011], which also induces a wedge between the expected return on capital and the risk-free rate, that is now determined by the change in entrepreneurial leverage. The rst chapter of thesis estimates three versions of Smets and Wouters [2003, 2007] using a Bayesian approach. Used as a benchmark, the rst version considers nancial markets as a veil and thus contains no nancial friction. The second version incorporates the Costly State Veri cation-type-friction à la Bernanke et al. [1999], while the third version includes the Costly Enforcement-type-friction à la Gertler and Karadi [2011]. The estimation results are used to answer to following questions: (i) Are models including nancial frictions more compatible with U.S. macroeconomic data than those with no frictions? (ii) which types of nancial friction are preferred by the data? Our ndings indicate that adding nancial frictions improves the New-Keynesian model's t to data, in terms of data marginal density. In the case of Costly Enforcement problem, these improvements are both substantial and robust, while they are marginal and not robust in the case of the Costly State Veri cation problem. Second, estimating the risk premium elasticity to entrepreneurial leverage, rather than calibrating it to values commonly used in the literature, helps the Bernanke et al. [1999] model version to perform more well. This nding suggests that this elasticity should be revised (downwards), relative to the prior belief established in the literature. The second chapter estimates three versions of Smets and Wouters [2003, 2007] via the Bayesian methodology for both the U.S. and Euro economies. The rst version serves as a basic model and considers nancial markets as veil, thereby contains no nancial frictions. The second version includes a Costly State Veri cation-type problem à la Bernanke et al. [1999],
