Cultural Spectrum in Arvind Adiga’s Selection Days
No full textCultural Studies have played a pivotal role in understanding and evaluating the power dynamics of the social, political, economic and ethical world order by empirically engaging and focusing on the present-day culture, tracing its historical roots and explicating its attributes with reference to a particular literary text and its reception in a society. Arvind Adiga, the Man-Booker Prize winning Indo-Australian author, in Selection Day, has adroitly detailed how cricket as an individual entity impacts the cultural phenomena of a society by confronting its inherent myriad issues. The narrative delves deep into the lives of two siblings - Radha and Manju, witnesses the dramatic turnaround of events and tries to capture the themes of unfulfilled desires and preordained destinies. The novel also explores how the sport holds different meanings and significance for different characters, each of whom view the game in the light of their own ideology. The author foresees and sensitizes the theme of homosexuality, which is still a taboo and been unheard of, within the sports fraternity. Adiga’s critique of the parental felony, embodied in Mohan Kumar, and its repercussions is the most compelling theme at the heart of this work of fiction. Selection Day powerfully binds together the societal phenomena of class construction, unquenchable thirst for money, sexual orientations and ideologies with a single thread and studies how culture, in itself, is an ever-evolving phenomenon
Antecedents and Enablers of Green Supply Chain Practices
No full textThe thesis titled antecedents and enablers of green supply chain practices focuses on one of the most contemporary issues in supply chain management. The literature review explores the existing literature and research work on green supply chain practices and develops a framework for the research. The research is qualitative in nature and data was collected from the three automobile component-manufacturing companies in India. Semi structured interviews were conducted over a period of 18 months.
There were three objectives for this thesis:
1. Describing the current state of green supply chain practices?
2. What are the antecedents and enablers for green supply chain practices?
3. What are the underlying mechanisms, if any?
The research work concludes by answering all the above three questions and also gives the future direction for research. The research work started by finding a gap for the empirical research in the context of green supply chain practices. The objective of the research was to focus on antecedents and enablers of green supply chain practices. Some contextual factors, inhibitors and consequences are also emerged during the pilot case study.
The research work is rigor and to ensure the rigor of the research design, five-stage process was used to structure the methodology. As a final check author assessed his research against the four basic tests commonly used in empirical research; construct validity, internal validity, external validity and reliability. The research study has contributed both to the development and testing of theory relating to the antecedents and enablers of green supply chain practices. The review of literature provided a synthesis of the underpinning bodies of literature that has not previously been conducted in this way. This resulted in the identification of ten core green supply chain practices for the development of antecedents and enablers that created the foundation for author’s empirical investigation. It was found that previous studies have been largely theoretical. The empirical studies that do exist have focused on one particular dyadic relationship with in green supply chain practices.
A double contribution has been made to testing the theory of green supply chain practices from a process and output perspective. As process perspective, a contribution has been made to methodology by developing a robust approach for conducting supply chain research beyond the dyad. From output perspective, the author has the empirical results from the three individual case studies and their cross-case comparison for dissemination to an academic audience.
Specific contribution of this research to theory development include:
1. Development of macro model of green supply chain practices with the inputs from literature.
2. The synthesis of ten core green supply chain practices with antecedents and enablers from existing body of literature enriched through empirical testing
3. Empirical derivation of three contextual factors.
Although the research work is new and contribute to the theory and practices, there are still some limitations of this research. Two minor limitations have been identified:
1. Generalizability of result to practice to practice: Due to the limited size of the case study approach, the results can only be generalized to theory and not to practice.
2. Variation in quality of information: The scope of data collection for all three case studies was same still the quality of information gathered was different. As good quality cross-case analysis was still possible but the relative strengths of the three cases varied.
Overall the research work is original, rigor, and contributes to the existing theory and also paves the path for future research work in the area of green supply chain practices
Transport of cryptosporidium parvum oocysts through disparate agricultural soils
No full textThe presence of Cryptosporidium parvum oocysts in source waters is a cause of major public health concern for drinking-water treatment plants. The oocysts occurring in the feces of livestock can be disseminated horizontally via runoff during storm events and contaminate surface waters. Soils are often the initial barrier to subsurface transport of Cryptosporidium parvum oocysts which receive oocyst-laden manure from grazing livestock. However, rainfall events can cause rapid vertical movement of oocysts through preferential flow paths in the soils leading to ground water contamination. A systematic study was undertaken to assess the efficacy of three disparate agricultural soils (two tropical, variable-charge soils of volcanic origin from Hawaii and a humic, quartz-rich temperate soil from Illinois) to remove Cryptosporidium parvum oocysts and oocystsized microspheres in batch and flow-through columns. To test the effect of soil mineralogy on oocysts transport, saturated flow-through column experiments were conducted by packing the three agricultural soils and injecting oocysts and microspheres. The results showed that oocysts were transported through preferential flow paths in high-clay, high-iron tropical soil from Hawaii and humic-rich quartz dominated temperate soil from Illinois. Transport through volcanic-ash soil collected from the island of Hawaii was highly reversible because of high soil organic matter content. The effects of dissolved organic carbon (DOC) on oocysts and microspheres transport through these soils were assessed in a subsequent phase of this study. DOC in form of natural organic matter enhanced the removal of oocyst-sized colloids (microspheres and oocysts), whereas surfactants lowered the removal efficiency of oocysts and microspheres. The transport potentials of oocysts and microspheres were affected differentially by the physicochemical properties of the soils. Whereas oocysts transport was more strongly affected by soil mineralogy, microspheres transport was much more sensitive to the nature of DOC.Ph.D
Trading arrangements and industrial development
No full textHow do different trading arrangements influence the industrialization process of developing countries? Can preferential trading arrangements (PTAs) be superior to multilateral liberalization, or at least an alternative when multilateral liberalization proceeds slowly? If so, what form should the PTAs take? Are developing countries better advised to seek PTAs with industrial countries or among themselves? Traditional analysis of these issues has been based on the idea of trade creation and trade diversion. The problem with this analysis is that it starts from assuming a pattern of comparative advantage of newly industrialized countries. The experience of these countries suggests the need for an analysis in which the pattern of comparative advantage is not set in stone but is potentially flexible, and in which less developed countries can develop and converge in both income and economic structure to industrial economies. The authors outline an alternative approach for analyzing the role of trade in promoting industrial development. There are few fundamental differences between countries that generate immutable patterns of comparative advantage. Instead the pattern of trade and development in the world economy is determined mainly by history. Cumulative causation has created concentrations of industrial activity in particular locations (industrial countries) and left other areas more dependent on primary activities. Economic development can be thought of as the spread of these concentrations from country to country. Different trading arrangements may have a major impact on this development process. By changing the attractiveness of countries as a base for manufacturing production they can potentially trigger or postpone industrial development. This approach explains why firms are reluctant to move to economies that have lower wages and labor costs, and shows how trade liberalization can change the incentives to become established in developing countries. It provides a mechanism through which import liberalization can have a powerful effect in promoting industrialization. And it suggests that import liberalization may create or amplify differences between liberalizing countries with the possible political tensions this may create. While these features are consistent with the world economy, they fall short of providing convincing empirical support for the approach. Using the approach, the authors derive number of conclusions about the effects of trade liberalization. First, that unilaterally liberalizing imports of manufactures can promote development of the local manufacturing industry. The mechanism is forward linkages from imported intermediates, but this may be interpreted as part of a wider package of linkages coming from these imports. Second, the gains from liberalization through PTA membership are likely to exceed those obtained from unilateral action. South-South PTAs will be sensitive to the market size of member states, and North-South PTAs seem to offer better prospects for participating Southern economies, if not for North and excluded countries. Third, the effects of particular schemes (such as the division of benefits between Southern economies) will depend on the characteristics of the countries and cross-country differences in these characteristics.Economic Theory&Research,Environmental Economics&Policies,Water and Industry,Labor Policies,Banks&Banking Reform,Economic Theory&Research,Environmental Economics&Policies,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT,Trade and Regional Integration,Water and Industry

An alloy selection and processing framework for nanocrystalline materials
No full textThis electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Thesis: Ph. D., Massachusetts Institute of Technology, Department of Materials Science and Engineering, 2018Cataloged from PDF version of thesis.Includes bibliographical references (pages 106-115).Nanocrystalline materials have a unique set of properties due to their nanometer-scale grain size. To harness these properties, grain growth in these materials needs to be suppressed, particularly in order to process bulk nanocrystalline components and to use them reliably. Alloying the material with the right elements has the potential to produce remarkably stable nanocrystalline states, particularly if the nanocrystalline state is thermodynamically stable against grain growth. This thesis builds upon previous models for selecting alloy combinations that lead to thermodynamic stability against grain growth, by developing frameworks that extend to negative enthalpy of mixing systems and ordered grain boundary complexions. These models are used to develop a generalized stability criterion based on bulk thermodynamic parameters, which can be used to select alloy systems that are formally stable against grain growth. A robust statistical mechanics framework is developed for reliable thermodynamic observations using Monte Carlo simulations to produce free energy diagrams and phase diagrams for stable nanocrystalline alloys.by Arvind R.

Statistical mechanics and combinatorics of some discrete lattice models
No full textMany problems in statistical physics involve enumeration of certain objects. In this thesis, we apply ideas from combinatorics and statistical physics to understand three different lattice models.
We investigate the structure of the nonequilibrium stationary state (NESS) of a system of first and second class particles on
L sites of a one-dimensional lattice in contact with first class particle reservoirs at the boundary sites and second class particles constrained to lie the system. The internal
dynamics are described by the usual totally asymmetric exclusion process (TASEP) with second class particles. We show in a conceptually simple way how pinned and unpinned (fat) shocks determine the general structure of the phase diagram. We also point out some unexpected features in the microscopic structure of the NESS both for finite L and in the limit of large L. In the latter case the local distribution of second class particles is given by an equilibrium pressure ensemble with a pair potential between neighboring particles which grows logarithmically with distance.
We model a long linear polymer constrained
between two plates as a walk on a two-dimensional lattice constrained to lie between two lines, x=y and x=y+w, which interacts with these lines via contact parameters s and t. The atomic steps of the walk can be taken to be from an arbitrary but fixed set S
with the only condition being that the first
coordinate of every element in S is strictly positive. For any such S and any w, we prescribe general algorithms (fully implemented in Maple) for the automated calculation of several mathematical and physical quantities of interest.
Ferrers (or Young) diagrams are very classical objects in representation theory, whose half-perimeter generating function of Ferrers diagrams is a straightforward rational function. We construct two new classes of Ferrers diagrams, which we call wicketed and gated Ferrers diagrams, which have internal voids in the shape of Ferrers diagrams, and calculate their half-perimeter generating functions, one of which is closely related to the generating function of the Catalan numbers, using a more abstract version of the usual transfer matrix method.Ph.D.Includes bibliographical references (p. 81-85)
