Jacob Hindman (1789-1827) was an American military officer who was a captain of the Second U.S. Artillery during the War of 1812. He commanded troops at the battles at Fort George and Stony Creek in 1813, and in June of that year became the major of the Second Artillery. He remained in this position until May of 1814 when the regiment was merged with the Corps of Artillery. During the Niagara campaign in 1814, Hindman’s company commanders included Nathan Towson, Thomas Biddle, John Ritchie, and Alexander Williams. During the British attack on Fort Erie in August 1814, Hindman led an assault for which he later received a brevet promotion to lieutenant colonel for “gallant conduct in the defense of Fort Erie”. In 1815, he received an additional brevet for “meritorious services”. He is generally regarded as one of the most successful artillerists of the War of 1812. James Hall (1793-1868) served with the U.S. military as a second lieutenant in the Second Artillery during the War of 1812. He fought in the Battle of Lundy’s Lane and was General Brown’s messenger during the attack on Fort Erie. He left the military in 1818 and became a newspaper editor and author. His experiences during the War of 1812 provided material for two stories, The Bearer of Despatches and Empty Pockets. Much of his work sought to popularize the West and promote western authors.

The Meese-Rogoff forecasting puzzle states that foreign exchange (FX) rates are unpredictable. Since one country’s macroeconomic conditions could affect the price of its national currency, we study the dynamic relations between the FX rates and some macroeconomic accounts. Our research tests whether the predictability of the FX rates could be improved through the advanced econometrics. Improving the predictability of the FX rates has important implications for various groups including investors, business entities and the government. The present thesis examines the dynamic relations between the FX rates, savings and investments for a sample of 25 countries from the Organization for Economic Cooperation and Development. We apply quarterly data of FX rates, macroeconomic indices and accounts including the savings and the investments over three decades. Through preliminary Augmented Dickey-Fuller unit root tests and Johansen cointegration tests, we found that the savings rate and the investment rate are cointegrated with the vector (1,-1). This result is consistent with many previous studies on the savings-investment relations and therefore confirms the validity of the Feldstein-Horioka puzzle. Because of the special cointegrating relation between the savings rate and investment rate, we introduce the savings-investment rate differential (SID). Investigating each country through a vector autoregression (VAR) model, we observe extremely insignificant coefficient estimates of the historical SIDs upon the present FX rates. We also report similar findings through the panel VAR approach. We thus conclude that the historical SIDs are useless in forecasting the FX rate. Nonetheless, the coefficients of the past FX rates upon the current SIDs for both the country-specific and the panel VAR models are statistically significant. Therefore, we conclude that the historical FX rates can conversely predict the SID to some degree. Specifically, depreciation in the domestic currency would cause the increase in the SID.

Recent work shows that a low correlation between the instruments and the included variables leads to serious inference problems. We extend the local-to-zero analysis of models with weak instruments to models with estimated instruments and regressors and with higher-order dependence between instruments and disturbances. This makes this framework applicable to linear models with expectation variables that are estimated non-parametrically. Two examples of such models are the risk-return trade-off in finance and the impact of inflation uncertainty on real economic activity. Results show that inference based on Lagrange Multiplier (LM) tests is more robust to weak instruments than Wald-based inference. Using LM confidence intervals leads us to conclude that no statistically significant risk premium is present in returns on the S&P 500 index, excess holding yields between 6-month and 3-month Treasury bills, or in yen-dollar spot returns.

This note develops general model-free adjustment procedures for the calculation of unbiased volatility loss functions based on practically feasible realized volatility benchmarks. The procedures, which exploit the recent asymptotic distributional results in Barndorff-Nielsen and Shephard (2002a), are both easy to implement and highly accurate in empirically realistic situations. On properly accounting for the measurement errors in the volatility forecast evaluations reported in Andersen, Bollerslev, Diebold and Labys (2003), the adjustments result in markedly higher estimates for the true degree of return-volatility predictability.

Les dysfonctions attentionnelles suivant un traumatisme craniocérébral (TCC) compliquent souvent la reprise des activités de la vie quotidienne et influencent négativement le pronostic de réinsertion socio-académique et professionnelle. Or, les cliniciens de réadaptation disposent d’un nombre limité d’outils de remédiation cognitive dont l’efficacité est démontrée et qui sont adaptés à une population francophone. Cette étude vise à démontrer l’efficacité d’un protocole d’entrainement intensif des fonctions attentionnelles : « Attention! Prêt? On s’enTraine! » (Séguin, Lahaie & Beauchamp, 2012), basé sur une adaptation française de l’« Attention Process Training-I » (APT-I; Sohlberg & Mateer, 1987). Dix-sept participants ayant subi un TCC et présentant des déficits attentionnels ont reçu 15 séances d’entrainement attentionnel avec le programme « Attention! Prêt? On s’enTraine! » (n = 8) ou de l’aide aux devoirs (n = 9). Suite à l’intervention, les participants du groupe expérimental ont amélioré leur rendement dans plusieurs fonctions ciblées par l’intervention attentionnelle, notamment au niveau du balayage visuel, de l’attention sélective et de l’alternance attentionnelle. De plus, les gains se sont généralisés à des fonctions connexes, puisqu’une meilleure performance a été retrouvée dans des tâches de mémoire de travail, d’inhibition, de flexibilité cognitive et de planification visuoconstructive. La démonstration de l’effet positif d’un entrainement intensif sur le rendement attentionnel pourrait inciter les cliniciens et chercheurs à développer et à valider d’autres protocoles de remédiation cognitive francophones, pour les fonctions attentionnelles ou d’autres sphères de la cognition. Par le fait même, le pronostic fonctionnel de la clientèle pédiatrique en traumatologie en sera potentialisé.

Dans cette thèse, nous étudions quelques problèmes fondamentaux en mathématiques financières et actuarielles, ainsi que leurs applications. Cette thèse est constituée de trois contributions portant principalement sur la théorie de la mesure de risques, le problème de l’allocation du capital et la théorie des fluctuations. Dans le chapitre 2, nous construisons de nouvelles mesures de risque cohérentes et étudions l’allocation de capital dans le cadre de la théorie des risques collectifs. Pour ce faire, nous introduisons la famille des "mesures de risque entropique cumulatifs" (Cumulative Entropic Risk Measures). Le chapitre 3 étudie le problème du portefeuille optimal pour le Entropic Value at Risk dans le cas où les rendements sont modélisés par un processus de diffusion à sauts (Jump-Diffusion). Dans le chapitre 4, nous généralisons la notion de "statistiques naturelles de risque" (natural risk statistics) au cadre multivarié. Cette extension non-triviale produit des mesures de risque multivariées construites à partir des données financiéres et de données d’assurance. Le chapitre 5 introduit les concepts de "drawdown" et de la "vitesse d’épuisement" (speed of depletion) dans la théorie de la ruine. Nous étudions ces concepts pour des modeles de risque décrits par une famille de processus de Lévy spectrallement négatifs.

The rapid growth of the populous Asian economies provokes profound economic changes and a shift in the balance of power. On the economic front, Asian leaders are confronted with the need to preserve the stability that has underpinned their prosperity, maintain an environment conducive to trade and investments and encourage domestic consumption while avoiding ecological disasters. Internationally, business competition will intensify with the strong presence of Asian manufacturers in global supply chains, growing price competition from Asian firms in domestic markets and global competition for energy, food, minerals and other commodities. Geopolitical concerns stem, in part, from Asia’s global quest for critical resources, conflicting territorial and maritime disputes and increasing military expenditures which affect security dynamics. China’s assertiveness over its periphery prompts an arm’s race in the region and concerns about Sino-American relations even though U.S.-Chinese relations may be less risky than China’s relations with its neighbours. The United States remains a key player in the Asia-Pacific region, with the capacity to alter balances and affect outcomes. Globally, the United States capacity to lead is now diminished and will continue to be so for the foreseeable future. Since no rising power is capable of exercising global leadership, a return to the "old normal" where no one power in geopolitical or economic terms dominates the world is to be expected.

The present scenario of industrial fishing in India is that most of large trawlers are based at Visakhapatnam and congregate in the potential shrimp ground in the upper East coast of India commonly known as the Sandheads. These are outriggcr vessels operating two or four trawl nets along with a testing trawl called try net. In the early Seventies these vessels were operating on a very high economic return which was evident from the steady increase in number of outriggers over a period of twenty years. Since the total allowable catch has to be shared by all vessels including the increasing fleet, reduction per vessel output is bound to happen. Therefore some of them could not survive the competition and withdrew from the scene. The number of outriggers did not increase subsequently. However, there arose a doubt whether the existing fleet of about 180 vessels are fishing economically or whether there is any scope for further introduction of industrial vessels in the region. This study is focussing to the techno economic aspects of industrial fishing in the upper East coast of India

The present research programme envisages a comparative study of the effects of two piscicides of plant origin, viz., mahua oil cake, a derivative from the plant fig Iatifolia and croton seed, a product from the plant Croton tiglium. Although some reports on the effects of mahua oil cake and croton seed on fresh water pond culture systems are available, information on their effect on brackishwater culture systems are rather scanty This was the guiding principle for launching the present study It is hoped that the findings will enable aquaculturists to make use of the piscicides in a more rational and efficient way, and will go a long way towards realising the maximum return liom culture systems without hampering the environment. The thesis is presented in seven chapters such as Introduction, Review of literature, Materials and Methods, Results, Discussion, Summary and Bibliography

A study focusing on the identification of return generating factors and to the extent of their influence on share prices the outcome will be a tool for investment analysis in the hands of investors portfolio managers and mutual funds who are mostly concerned with changing share prices. Since the study takes into account the influence of macroeconomic variables on variations in share returns by using the outcome the government can frame out suitable policies on long term basis and that will help in nurturing a healthy economy and resultant stock market. As every company management tries to maximize the wealth of the share holders a clear idea about the return generating variables and their influence will help the management to frame various policies to maximize the wealth of the shareholders.

The present study is the first attempt to understand population characteristics of the deep-sea pandalid shrimp, P. quasigrandis and to assess the status of these resources off Kerala coast.Total mortality coefficient (Z) of P. quasigrandis estimated by various methods.Natural mortality coefficient (M) calculated was 0.65 and 1.02 by Pauly‟sempirical formula and Srinaths‟s formula respectively The deep-sea shrimp P. quasigrandis exploited from the present fishing ground and their monetary return has started showing a declining trend. By observing the current yield and economic return, there is no further scope for increasing the catch from the present fishing ground. The study indicated that majority of the deep-sea shrimp trawlers, especially targeted for pandalid shrimps still concentrated off Kollam area (Quilon Bank). Even though researchers had located several potential deep-sea fishing grounds based on exploratory surveys in Indian EEZ , fishermen are unaware of these fishing grounds located and hence sharing the information about new potential deep-sea fishing grounds could avert the possible stock decline due to the intensive targeted deep-sea shrimp fishery in the Quilon Bank. Hence, the present study recommended that part of the effort from existing fishing grounds may be shifted to newly located deep-sea fishing grounds which will help in a sustainableexploitation of deep-sea resources off Kerala coast.
