Nonparametric Slope Estimators for Fixed-Effect Panel Data

In panel data the interest is often in slope estimation while taking account of the unobserved cross sectional heterogeneity. This paper proposes two nonparametric slope estimation where the unobserved effect is treated as fixed across cross section. The first estimator uses first-differencing transformation and the second estimator uses the mean deviation transformation. The asymptotic properties of the two estimators are established and the finite sample Monte Carlo properties of the two estimators are investigated allowing for systematic dependence between the cross-sectional effect and the independent variable. Simulation results suggest that the new nonparametric estimators perform better than the parametric counterparts. We also investigate the finite sample properties of the parametric within and first differencing estimators. A very common practice in estimating earning function is to assume earnings to be quadratic in age and tenure, but that might be misspecified. In this paper we estimate nonparametric slope of age and tenure on earnings using NLSY data and compare it to the parametric (quadratic) effect.Nonparametric, Fixed-effect, Kernel, Monte carlo

Immigrant Networks and U.S. Bilateral Trade: The Role of Immigrant Income

This paper examines the role of immigrant networks on trade, particularly through the demand effect. First, we examine the effect of immigration on trade when the immigrants consume more of the goods that are abundant in their home country than the natives in a standard Heckscher-Ohlin model and find that the effect of immigration on trade is a priori indeterminate. Our econometric gravity model consists of 63 major trading and immigrant sending countries for the U.S. over 1991-2000. We find that the immigrants' income, mostly through the demand effect, has a significant negative effect on U.S. imports. However, if we include the effect of the immigrant income interacted with the size of the immigrant network, measured by the immigrant stock, we find that the higher the immigrant income the lower is the immigrant network effect for both U.S. exports and imports. This we find in addition to the immigrant stock elasticity of 0.27% for U.S. exports and 0.48% for U.S. imports. Capturing the immigrant assimilation with the level of immigrant income, this paper finds that the immigrant network effect on trade flows is weakened by the increasing level of immigrant assimilation.immigrant networks, immigrant assimilation, demand effect, trade

Design of Electric Vehicle

The aim of this thesis work 'Design of electric vehicle including different power train components' is to design an energy model of electric vehicle including different power train components with the application of a design and simulation tool, which in this thesis work would be MATLAB Simulink software. With this design and simulation, we expect to find the energy consumption by a vehicle by virtue of different types of forces acting on vehicle when subjected to different standard driving cycles. This work also includes a survey of different vehicles which runs on electric propulsion either only or in assisted mode in the present market

Immigrant Networks and the U.S. Bilateral Trade: the Role of Immigrant Income

This paper examines the role of immigrant networks on trade, particulalry through the demand effect.

A Culturally Grounded Approach to Nepalese Grandmothers’ Caring Work: Developing Dohori as a Narrative Methodology

The social sciences have a growing seismic shift from prioritising positivist, objective, and generalizable knowledge to accepting subjective qualitative knowledge. This has given rise to various art-based methods that leverage multi-sensory storytelling/narrative. To further advance innovation in qualitative narrative methods, I will present the Dohori narrative, an indigenous Nepali poetic storytelling method for narrative research with older grandmothers doing care work. I start by presenting a discourse on Dohori to understand better the history and traditional and cultural underpinning of the method. Provided a brief background to Nepali grandmother immigrants and then discussed the promise of Dohori as a form of culturally relevant narrative interviewing with this population. To demonstrate this, I provide an examplar case study adopting a conventional narrative interview and then Dohori to show the differences. The study showed that Dohori has the potential to elicit stories, emotions, and tacit knowledge and access other areas of consciousness that traditional narrative interviews are not privy to. I conclude by arguing for the adoption of Dohori and similar dialogical poetic methods for research with indigenous populations, especially minority groups with limited voice

Actel Parts Usage in GSFC Projects

The purpose of this paper is to provide an overview of the Actel field programmable gate array (FPGA) issues and investigations to date, provide information to GSFC parts engineers on the risks associated with the use of these parts in flight, provide procurement options for their respective projects, and provide general guidance for use of these devices if no other acceptable options exist

Formal Verification of Full-Wave Rectifier: A Case Study

We present a case study of formal verification of full-wave rectifier for analog and mixed signal designs. We have used the Checkmate tool from CMU [1], which is a public domain formal verification tool for hybrid systems. Due to the restriction imposed by Checkmate it necessitates to make the changes in the Checkmate implementation to implement the complex and non-linear system. Full-wave rectifier has been implemented by using the Checkmate custom blocks and the Simulink blocks from MATLAB from Math works. After establishing the required changes in the Checkmate implementation we are able to efficiently verify the safety properties of the full-wave rectifier.Comment: The IEEE 8th International Conference on ASIC (IEEE ASICON 2009), October 20-23 2009, Changsha, Chin

Tilo’s Coming to Terms With Her Conflicting Identity: A Study of Her Displaced Self in The Mistress of Spices

The term ‘diaspora’ was initially used for the displacement of Jews but now it has become an umbrella term for all kinds of displacement from one country to another (be it forced or willing) by people of all cultures and communities. According to Makarand Paranjape, “The diaspora... must involve a cross-cultural or cross-civilizational passage. It is only such a crossing that results in the unique consciousness of the diasporic” (Paranjape 6). The most basic problems experienced by diasporic existence are nostalgia, alienation and the problem of assimilation. While the first generation immigrants suffer from nostalgia, those who belong to second generation or generations after that suffer from the problem of assimilation, i.e. they earnestly desire to get assimilated in their country of adoption and become part of it but their hyphenated identity never leaves them. Alienation is a common feature to all generations of immigrants, first generation immigrants are not one with the new surroundings (emotionally and culturally) and feel alienated whereas the next generations become part of the new culture but are still considered outsiders hence made to feel alienated. This leads to an identity crisis. It is this problem of identity which forms the soul of one’s diasporic existence. Divakaruni’s protagonist Tilo represents all these aspects of diasporic existence. She does not merely represent these aspects in the life of people but is herself a physical embodiment of diasporic existence. She is both, a person living a diasporic life as well as the diasporic life itself
