Generally, toxic-metabolic diseases affecting the central nervous system can hardly be differentiated just on the basis of their clinical presentation. However, some typical neuroradiological features can guide the correct diagnosis. In this context, magnetic resonance imaging is an important tool which, in association with clinical and laboratory data, can establish an early and specific treatment. The present pictorial essay with selected cases from the archives of the authors' institution describes imaging findings which might help in the etiologic diagnosis of toxic-metabolic diseases.

The present essay is illustrated with magnetic resonance images obtained at the authors' institution over the past 15 years and discusses the main imaging findings of intraventricular tumor-like lesions (colloid cyst, oligodendroglioma, astroblastoma, lipoma, cavernoma) and of inflammatory/infectious lesions (neurocysticercosis and an atypical presentation of neurohistoplasmosis). Such lesions represent a subgroup of intracranial lesions with unique characteristics and some imaging patterns that may facilitate the differential diagnosis. PMID:25741092

Most malignant liver tumors are represented by hepatocellular carcinoma and cholangiocarcinoma; however a variety of other uncommon hepatic lesions might also be found. Common lesions such as hemangioma, focal nodular hyperplasia and metastases are well known and have already been extensively documented in the literature. The diagnosis of typical hepatic lesions may be done with some reliability by means of several imaging methods; on the other hand, uncommon lesions normally represent a diagnostic challenge for the radiologist. In this first part of the study, the authors will approach five uncommon liver tumors - angiosarcoma, angiomyolipoma, cystadenoma/biliary carcinoma, epithelioid hemangioendothelioma, and fibrolamellar hepatocellular carcinoma -, describing their main characteristics and image findings with focus on computed tomography and magnetic resonance imaging.

In cases where typical aspects are shown, the diagnosis of most frequent hepatic lesions can be made with some safety by means of several imaging methods; on the other hand, uncommon lesions generally represent a diagnostic challenge for the radiologist. In the present second part of the study, the authors describe four rare hepatic lesions, as follows: primary hepatic lymphoma, myofibroblastic tumor, primary hepatic neuroendocrine tumor and desmoplastic small round cell tumor, approaching their main characteristics and imaging findings with emphasis on computed tomography and magnetic resonance imaging.
The essay regularly comes under attack. It is criticised for being rigidly linear rather than flexible and reflective.

Interests have been a central focus of counselling psychology (and vocational psychology in particular) for over 100 years. The awareness of professional interests increases self-knowledge and provides occupational information. In career counselling, vocational interests are assessed more frequently than any other vocational construct, though early evaluations (before 13 years old) of professional interests are very rare. The aim of this research is to examine the 3IP construct (Iconographic Professional Interests Inventory; an inventory composed of 65 stylised pictures that represent people in the act of performing a job) in depth, testing more models in addition to the 19 vocational areas proposed in the 3IP manual. Results show that most of the vocational areas can be grouped into 4 second-level areas (“things”, “people”, “leisure”, and “culture”). Moreover, Holland’s RIASEC model is tested; an accurate selection of items reveals that this model works well using 24 specific jobs. The research concludes that the inventory has good psychometric qualities which can grow further by mean of the increasing, in a targeted way, of the number of jobs. PMID:27247679

Fetal development is studied since the advent of two-dimensional ultrasonography. However, a detailed assessment of structures and surfaces improved with three-dimensional ultrasonography. Currently, it is possible to identify embryonic components and fetal parts with greater detail, at all pregnancy trimesters, using the HD live software, where the images gain realistic features by means of appropriate control of lighting and shadowing effects. In the present study, the authors utilized this resource to follow-up, by means of images, the development of a normal pregnancy along all trimesters.
Bruce Pirie offers the following criticism about formula essays: "What does a five-paragraph essay teach about writing?

Introduction: Achondroplasia is the most frequent form of short-limb dwarfism. Affected individuals exhibit short stature caused by rhizomelic shortening of the limbs, characteristic facies with frontal bossing and mid-face hypoplasia, genu varum, and trident hand. Although the etiology of this disease was reported in 1994, evidence of this disease in ancient populations has been found in populations of ancient Egypt (2500 BC) and it has been documented in ancient American populations. Objective: To analyze the presence of individuals with achondroplasia in the Mayan state society of Mexico and Guatemala, during the Classical (100- 950 AC ) and Post-Classical (950 - 1519 AC ) periods; likewise, in the hierarchical-chieftain society of Tumaco-la Tolita (300 BC - 600 AC ) from the Colombia-Ecuador Pacific coast, and the Moche state society (100 - 600 AC ) from the northern coast of Peru. Methods: Iconographic and clinical-morphological studies of some of the most important artistic representations of individuals of short stature in these three cultures. Conclusion: We present the hypothesis that the individuals with short stature were somehow associated with the political and religious power elite. PMID:24893194

This dissertation consists of three essays in applied microeconomics. Each essay explores a different issue of economic interest. The essay in Chapter 2 describes an experiment designed to investigate if using assets with an intrinsic value that increases over time leads to persistent undervaluation in laboratory asset trading markets. This question has not previously been investigated by researchers. Results from ten sessions are reported. Three used assets with an intrinsic value that decreased over time. The results from these sessions are consistent with the findings by prior researchers who frequently observed price bubbles in laboratory asset trading experiments. The remaining seven sessions used assets with an intrinsic value that increased over time. In all these sessions trading generally occurred at prices below the asset's intrinsic value. In Chapter 3, in an essay co-authored with Adrian Stoian, we study road running races. Tournaments, where ordinal position determines rewards, are an important component of our economy. By studying sporting tournaments, we hope to shed light on the nature of other economically significant tournaments where data may be less readily available. We separately quantify the sorting and incentive effects of tournament prizes by employing a novel two-part model which we apply to a unique data set of road running race results. We present a counterfactual example of how a hypothetical change in prizes would be predicted to change race participation and speed. In Chapter 4, in an essay co-authored with Jedidiah Brewer and Joseph Cullen, we examine the combined effects of the locations and the brands of retail gasoline outlets in Tucson, Arizona on market prices. We apply an innovative approach to model the impact of competing gas stations that avoids limiting analysis to predetermined nearby locations. We show that increased brand diversity is associated with higher prices and that gas stations affiliated with mass
Three independent studies in applied economics are presented. The first essay looks at the US natural gas industrial sector and estimates welfare effects associated with the changes in natural gas regulatory policy over the past three decades. Using a disequilibrium model suited to the natural gas industry, welfare transfers and deadweight losses are calculated. Results indicate that deregulation policies, beginning with the NGPA of 1978, have caused the industry to become more responsive to market conditions. Over time, regulated prices converge toward the estimated equilibrium prices. As a result of this convergence, deadweight losses associated with regulation are also diminished. The second essay examines the discounted utility model (DU), the standard model used for intertemporal decision-making. Prior empirical studies challenge the descriptive validity of the model. This essay addresses the four main inconsistencies that have been raised: domain dependence, magnitude effects, time effects, and gain/loss asymmetries. These inconsistencies, however, may be the result of the implicit assumption of linear utility and not a failure of the DU model itself. In order to test this hypothesis, data was collected from in-class surveys of economics classes at Mississippi State University. A random effects model for panel data estimation which accounts for individual specific effects was then used to impute discount rates measured in terms of dollars and utility. All four inconsistencies were found to be present when the dollar measures were used. Using utility measures of the discount rate resolved the inconsistencies in some cases. The third essay brings together two perspectives in the study of religion and economics: modeling religious behavior using economic tools and variables, and modeling economic behavior using religious variables. A system of ordered probit equations is developed to simultaneously model religious activities and economic outcomes. Using data
Revolutionary developments in Europe and their global reverberations since 1989 have affected certain aspects of our national strategy. This volume presents nine essays dealing imaginatively with the issues of the post-Cold War period. One of them addresses general US strategy for the 1990s. Three focus on high-level strategic matters: the future of flexible response, antisatellite weapons, and forward, mobile defenses. The others address US chemical weapons policy, use of civilian aircraft for defense airlift, neutrality of the Panama Canal after 1999, arms sales by China, and strategic defense at reduced cost.

This dissertation consists of three independent essays in macroeconomics. The first essay studies the transition to a low carbon economy using an extension of the neoclassical growth model featuring endogenous energy efficiency, exhaustible energy and explicit climate-economy interaction. I derive the properties of the laissez faire equilibrium and compare them to the optimal allocations of a social planner who internalizes the climate change externality. Three main results emerge. First, the exhaustibility of energy generates strong market based incentives to improve energy efficiency and reduce CO 2 emissions without any government intervention. Second, the market and optimal allocations are substantially different suggesting a role for the government. Third, high and persistent taxes are required to implement the optimal allocations as a competitive equilibrium with taxes. The second essay focuses on coal fired power plants (CFPP) - one of the largest sources of CO2 emissions globally - and their generation efficiency using a macroeconomic model with an embedded CFPP sector. A key feature of the model is the endogenous choice of production technologies which differ in their energy efficiency. After establishing four empirical facts about the CFPP sector, I analyze the long run quantitative effects of energy taxes. Using the calibrated model, I find that sector-specific coal taxes have large effects on generation efficiency by inducing the use of more efficient technologies. Moreover, such taxes achieve large CO2 emissions reductions with relatively small effects on consumption and output. The final essay studies the procyclicality of fiscal policy in developing countries, which is a well-documented empirical observation seemingly at odds with Neoclassical and Keynesian policy prescriptions. I examine this issue by solving the optimal fiscal policy problem of a small open economy government when the interest rates on external debt are endogenous. Given an

The first essay measures the impact of an outbreak of pediatric leukemia on local housing values. A model of residential location choice is used to describe conditions under which the gradient of the hedonic price function with respect to health risk is equal to household marginal willingness to pay to avoid pediatric leukemia risk. This equalizing differential is estimated using property-level sales records from a county in Nevada where residents have recently experienced a severe increase in pediatric leukemia. Housing values are compared before and after the increase with a nearby county acting as a control group. The results indicate that housing values decreased 15.6% during the period of maximum risk. Results are similar for alternative measures of risk and across houses of different sizes. With risk estimates derived using a Bayesian learning model the results imply a statistical value of pediatric leukemia of $5.6 million. The results from the paper provide some of the first market-based estimates of the value of health for children. The second essay evaluates the cost-effectiveness of public incentives that encourage households to purchase high-efficiency durable goods. The demand for durable goods and the demand for energy and other inputs are modeled jointly as the solution to a household production problem. The empirical analysis focuses on the case of clothes washers. The production technology and utilization decision are estimated using household-level data from field trials in which participants received front-loading clothes washers free of charge. The estimation strategy exploits this quasi-random replacement of washers to derive robust estimates of the utilization decision. The results indicate a price elasticity, -.06, that is statistically different from zero across specifications. The parameters from the utilization decision are used to estimate the purchase decision using data from the Consumer Expenditure Survey, 1994-2002. Households

The term rhombencephalitis refers to inflammatory diseases affecting the hindbrain (brainstem and cerebellum). Rhombencephalitis has a wide variety of etiologies, including infections, autoimmune diseases, and paraneoplastic syndromes. Infection with bacteria of the genus Listeria is the most common cause of rhombencephalitis. Primary rhombencephalitis caused by infection with Listeria spp. occurs in healthy young adults. It usually has a biphasic time course with a flu-like syndrome, followed by brainstem dysfunction; 75% of patients have cerebrospinal fluid pleocytosis, and nearly 100% have an abnormal brain magnetic resonance imaging scan. However, other possible causes of rhombencephalitis must be borne in mind. In addition to the clinical aspects, the patterns seen in magnetic resonance imaging can be helpful in defining the possible cause. Some of the reported causes of rhombencephalitis are potentially severe and life threatening; therefore, an accurate initial diagnostic approach is important to establishing a proper early treatment regimen. This pictorial essay reviews the various causes of rhombencephalitis and the corresponding magnetic resonance imaging findings, by describing illustrative confirmed cases.

This dissertation consists of three self-contained applied microeconomics essays on topics related to behavioral economics and industrial organization. Chapter 1 studies how sentiment as a result of sports event outcomes affects consumers' tipping behavior in the presence of social norms. I formulate a model of tipping behavior that captures consumer sentiment following a reference-dependent preference framework and empirically test its relevance using the game outcomes of the NBA and the trip and tipping data on New York City taxicabs. While I find that consumers' tipping behavior responds to unexpected wins and losses of their home team, particularly in close game outcomes, I do not find evidence for loss aversion. Coupled with the findings on default tipping, my empirical results on the asymmetric tipping responses suggest that while social norms may dominate loss aversion, affect and surprises can result in freedom on the upside of tipping. Chapter 2 utilizes a novel data source of airline entry and exit announcements and examines how the incumbent airlines adjust quality provisions as a response to their competitors' announcements and the role of timing in such responses. I find no evidence that the incumbents engage in preemptive actions when facing probable entry and exit threats as signaled by the competitors' announcements in either short term or long term. There is, however, evidence supporting their responses to the competitors' realized entry or exit. My empirical findings underscore the role of timing in determining preemptive actions and suggest that previous studies may have overestimated how the incumbent airlines respond to entry threats. Chapter 3, which is collaborated with Benjamin Ho, investigates the habit formation of consumers' thermostat setting behavior, an often implicitly made decision and yet a key determinant of home energy consumption and expenditures. We utilize a high frequency dataset on household thermostat usage and find that

Three essays in the field of public economics are included in this thesis. Chapter 1 begins this work with an introduction to public economics and places the remaining chapters in context. Like all economic agents, the government must manage its cash position. Chapter 2 considers this activity. Short-term financial requirements cause the government to solicit the market for bills not previously scheduled (Cash Management Bills). Using data from the US Treasury's Proprietary Domestic Finance Database, this chapter shows that these bills have higher costs than normal bills, suggesting that both Treasury and financial markets appreciate that demand is more inelastic for these instruments. In addition, this research identifies several factors that increase finance costs for Treasury in meeting short-term financial need. Chapter 3 explores location choices for generation investment in a re-regulated electricity market. Recently, there have been significant changes in the regulation of electricity in the State of California. These changes may affect generation investment behavior within the State, an important consideration for policy makers. This work identifies the impact of public sector regulatory change on private sector investment outcomes, by comparing the location and scope of electricity generation projects before and after two specific regulatory changes in air quality management and transmission tariff charges, while controlling for expected population growth patterns within the State. Significant changes in location preference are identified using factors for the northern and southern transmission zones, NP15 and SP15, the intermediate zone ZP26, and for areas outside of ISO control. Chapter 4 considers Disability Insurance and individual public pension investment accounts. Current debate on the Social Security Administration's long-term finance of benefits includes proposals for independent private investment via individual accounts. The author investigates

Ultrasonography (USG) is the primary method for antenatal fetal evaluation. However, fetal magnetic resonance imaging (MRI) has now become a valuable adjunct to USG in confirming/excluding suspected abnormalities and in the detection of additional abnormalities, thus changing the outcome of pregnancy and optimizing perinatal management. With the development of ultrafast sequences, fetal MRI has made remarkable progress in recent times. In this pictorial essay, we illustrate a spectrum of structural abnormalities affecting the central nervous system, thorax, genitourinary and gastrointestinal tract, as well as miscellaneous anomalies. Anomalies in twin gestations and placental abnormalities have also been included. PMID:27081224

In the first essay, a theoretical model is developed to determine the time path of optimal access price in the telecommunications industry. Determining the optimal access price is an important issue in the economics of telecommunications. Setting a high access price discourages potential entrants; a low access price, on the other hand, amounts to confiscation of private property because the infrastructure already built by the incumbent is sunk. Furthermore, a low access price does not give the incumbent incentives to maintain the current network and to invest in new infrastructures. Much of the existing literature on access pricing suffers either from the limitations of a static framework or from the assumption that all costs are avoidable. The telecommunications industry is subject to high stranded costs and, therefore, to address this issue a dynamic model is imperative. This essay presents a dynamic model of one-way access pricing in which the compensation involved in deregulatory taking is formalized and then analyzed. The short run adjustment after deregulatory taking has occurred is carried out and discussed. The long run equilibrium is also analyzed. A time path for the Ramsey price is shown as the correct dynamic price of access. In the second essay, a theoretical model is developed to determine the time path of optimal access price for an infrastructure that is characterized by congestion and lumpy investment. Much of the theoretical literature on access pricing of infrastructure prescribes that the access price be set at the marginal cost of the infrastructure. In proposing this rule of access pricing, the conventional analysis assumes that infrastructure investments are infinitely divisible so that it makes sense to talk about the marginal cost of investment. Often it is the case that investments in infrastructure are lumpy and can only be made in large chunks, and this renders the marginal cost concept meaningless. In this essay, we formalize a model of

To induce utilities in the gas distribution market to operate efficiently, US states have deployed consumer choice programs, price caps, and variations of sliding scale plans. My first essay studies the impact of these restructuring and deregulation efforts on consumer rates, using panel data from a custom survey of state commissions and the Department of Energy. I estimate the residential, small commercial and industrial price equations jointly, and use instrumental variables to control for the potentially endogenous demand and status of deregulation. Consumer choice programs lower the prices by 2.2-20.1% compared to the rate of return regulation, benefiting industrial consumers the most and households the least. These effects appear even one to two years prior to the programs' implementation, and become stronger over time. Price caps lower all prices by 0.0-20.0%, with the same ranking. The impacts of sliding scale plans are close to zero, between -2.6% and +4.0% The second paper evaluates health damages caused by air concentrations of SO2 under three alternative environmental policies leading to identical aggregate emissions: emission caps, a nationwide emission tax, and a system of tradable emission allowances such as the one currently used in the US. The numerical model of the industry finds generators' output, participation in energy trade and SO2 abatement effort under each policy. The resulting SO2 concentrations are used to derive the aggregate health damages using estimates in the medical literature. SO2 concentrations vary across policies even when the aggregate emissions are the same. These variations translate into substantially different losses for any individual state, and, nationwide, to hundreds of millions of dollars of difference in aggregate damages. Emission caps are found to lead to the lowest damages, outperforming the currently used system of allowances by 452 million. A uniform emission tax leads to very similar damages as the system of

The following dissertation contains two distinct empirical essays which contribute to the overall field of Financial Economics. Chapter 1, entitled "The Determinants of Dynamic Dependence: An Analysis of Commodity Futures and Equity Markets," examines the determinants of the dynamic equity-commodity return correlations between five commodity futures sub-sectors (energy, foods and fibers, grains and oilseeds, livestock, and precious metals) and a value-weighted equity market index (S&P 500). The study utilizes the traditional DCC model, as well as three time-varying copulas: (i) the normal copula, (ii) the student's t copula, and (iii) the rotated-gumbel copula as dependence measures. Subsequently, the determinants of these various dependence measures are explored by analyzing several macroeconomic, financial, and speculation variables over different sample periods. Results indicate that the dynamic equity-commodity correlations for the energy, grains and oilseeds, precious metals, and to a lesser extent the foods and fibers, sub-sectors have become increasingly explainable by broad macroeconomic and financial market indicators, particularly after May 2003. Furthermore, these variables exhibit heterogeneous effects in terms of both magnitude and sign on each sub-sectors' equity-commodity correlation structure. Interestingly, the effects of increased financial market speculation are found to be extremely varied among the five sub-sectors. These results have important implications for portfolio selection, price formation, and risk management. Chapter 2, entitled, "US Community Bank Failure: An Empirical Investigation," examines the declining, but still pivotal role, of the US community banking industry. The study utilizes survival analysis to determine which accounting and macroeconomic variables help to predict community bank failure. Federal Deposit Insurance Corporation and Federal Reserve Bank data are utilized to compare 452 community banks which failed between
Saavedra, Eduardo Humberto
This dissertation consists of three essays. The first essay, The Hold-Up Problem in Public Infrastructure Franchising, characterizes the equilibria of the investment decisions in public infrastructure franchising under incomplete contracting and ex-post renegotiation. The parties (government and a firm) are unable to credibly commit to the contracted investment plan, so that a second step investment is renegotiated by the parties at the revision stage. As expected, the possibility of renegotiation affects initial non-verifiable investments. The main conclusion of this essay is that not only underinvestment but also overinvestment in infrastructure may arise in equilibrium, compared to the complete contracting case. The second essay, Alternative Institutional Arrangements in Network Utilities: An Incomplete Contracting Approach, presents a theoretical assessment of the efficiency implications of privatizing natural monopolies which are vertically related to potential competitive firms. Based on the incomplete contracts and asymmetric information paradigm. I develop a model that analyzes the relative advantages of different institutional arrangements---alternative ownership and market structures in the industry--- in terms of their allocative and productive efficiencies. The main policy conclusion of this essay is that both ownership and the existence of conglomerates in network industries matter. Among other conclusions, this essay provides an economic rationale for a mixed economy in which the network is public and vertical separation of the industry when the natural monopoly is under private ownership. The last essay, Opportunistic Behavior and Legal Disputes in the Chilean Electricity Sector, analyzes post-contractual disputes in this newly privatized industry. It discusses the presumption that opportunistic behavior and disputes arise due to inadequate market design, ambiguous regulation, and institutional weaknesses. This chapter also assesses the presumption

In these essays, I examine (i) the empirical methods that are widely used in the literature to measure total factor productivity growth and (ii) the impact of nationalization on productivity in the oil industry. The first chapter, which is an ongoing work with SHI, Wei, investigates two empirical measures, quantity-based (primal) measure and price-based (dual) measure, of total factor productivity growth. My co-author and I analyze how these two measures are affected by output market imperfection or variable capacity utilization. We find that under constant-returns-to-scale production function assumption, existence of the imperfect competition in the output market creates a gap between the measured TFP growth and the true TFP growth, no matter which method is used. However, theoretically, it does not affect the equivalence between the two measures. Under variable capacity utilization, we show that constant-returns-to-scale assumption is almost enough to guarantee the validity of the two methods in correctly capturing the true TFP growth. In the second and third chapters, I analyze the link between nationalization and productivity. The second chapter documents the trends in expropriation acts, and evaluates the impact of expropriations on labor productivity of resource-rich developing countries in the oil industry. In the first part of this chapter, I investigate the trends in the expropriation acts that took place in 102 developing countries during the period 1922-2006. I find that more than half of the acts occurred between 1970 and 1976, there has been an increase in the number of expropriations in recent years, and the extractive sector including petroleum is more likely to be expropriated. Motivated by these facts, in the second part, I examine the oil industry in a period of widespread expropriations, the 1970s. In a sample of major oil-producing countries including OPEC and non-OPEC members, I show that losses in relative labor productivity after
Shunda, Nicholas James
This dissertation contains a series of theoretical investigations of auction markets. The essays it contains cover wholesale electricity markets, a popular selling mechanism on eBay, and supplier entry into multi-unit procurement auctions. The study in Chapter 1 compares the procurement cost-minimizing and productive efficiency performance of the auction mechanism used by independent system operators in wholesale electricity auction markets in the U.S. with that of a proposed alternative. The current practice allocates energy contracts as if the auction featured a discriminatory final payment method when, in fact, the markets are uniform price auctions. The proposed alternative explicitly accounts for the market-clearing price during the allocation phase. We find that the proposed alternative largely outperforms the current practice on the basis of procurement costs in the context of simple auction markets featuring both day-ahead and real-time auctions and that the procurement cost advantage of the alternative is complete when we simulate the effects of increased competition. We also find that a tradeoff between the objectives of procurement cost minimization and productive efficiency emerges in our simple auction markets and persists in the face of increased competition. The study in Chapter 2 considers a possible rationale for an auction with a buy price. In an auction with a buy price, the seller provides bidders with an option to end the auction early by accepting a transaction at a posted price. The "Buy-It-Now" option on eBay is a leading example of an auction with a buy price. The study develops a model of an auction with a buy price in which bidders use the auction's reserve price and buy price to formulate a reference price. The model both explains why a revenue-maximizing seller would want to augment her auction with a buy price and demonstrates that the seller sets a higher reserve price when she can affect the bidders' reference price through the
This thesis exploits the boom in U.S. oil and gas production to explore several empirical questions in environmental and energy economics. In the first essay, statistical techniques are employed to evaluate learning-by-doing in the Bakken Shale Play. Furthermore, the essay demonstrates organizational forgetting and knowledge spillovers among firms. The results show rates of learning in an important sector the U.S. economy and may have broader lessons for productivity gains and losses. The second essay investigates interfirm learning economies in oil well drilling in terms of productivity improvements and increases in environmental safety. The empirical results improve our understanding of how interfirm relationships influence productivity as well as the drivers of environmental incidents. Lastly, the third essay analyzes the impacts of stricter environmental regulations on oil production and well drilling in North Dakota. The results have particular relevance for policymakers seeking to understand the trade-offs between resource development and environmental quality. These three essays ultimately expand our knowledge of how learning economies occur and the effects of environmental regulations on economic activity.

This thesis is comprised of three essays. The first two essays examine empirically the relationship between crude oil price and wholesale gasoline prices in the U.S. petroleum refining industry while the third essay determines the optimal combination of emissions tax and environmental research and development (ER&D) subsidy when firms organize ER&D either competitively or as a research joint venture (RJV). In the first essay, we estimate an error correction model to determine the effects of market structure on the speed of adjustment of wholesale gasoline prices, to crude oil price changes. The results indicate that market structure does not have a strong effect on the dynamics of price adjustment in the three regional markets examined. In the second essay, we allow for inventories to affect the relationship between crude oil and wholesale gasoline prices by allowing them to affect the probability of regime change in a Markov-switching model of the refining margin. We find that low gasoline inventory increases the probability of switching from the low margin regime to the high margin regime and also increases the probability of staying in the high margin regime. This is consistent with the predictions of the competitive storage theory. In the third essay, we extend the Industrial Organization R&D theory to the determination of optimal environmental policies. We find that RJV is socially desirable. In comparison to competitive ER&D, we suggest that regulators should encourage RJV with a lower emissions tax and higher subsidy as these will lead to the coordination of ER&D activities and eliminate duplication of efforts while firms internalize their technological spillover externality.

This essay examines the debate over the climatic consequences of global nuclear war as related in the so-called Nuclear Winter hypothesis. This review examines the major components of the theory and traces development of the scientific knowledge leading to a second phase of the controversy two years after the first hypothesis. The conclusions of the essay are that the original nuclear winter findings have been altered by later scientific study and, therefore, the political conclusions drawn by Carl Sagan in 1983 can no longer be supported by theory or facts. Continued use of the Crutzen-Birks (Ambio, 1982) and TTAPS (Science, December 1983) studies worst-case evidence from NCAR (Foreign Affairs, Summer 86) represents selective science. Arguing for strategic policy changes based on nuclear winter risks constitutes anti-nuclear rhetoric and not scientific reasoning.

Jung conceptualized the collective unconscious as the locus of the myths, the absolutely genuine and primary patterns of thinking and feeling of humanity. The legend of Oedipus or myth of incest is a irrefutable proof of its eternal validity. The present essay is an attempt to take an alternative look to a history that belong to all of us. Situations that are developed in this drama, like the characters involved in it may charge significance as an archetypal and essentially symbolic interpretation.
Kneifel, Joshua D.
Environmental issues have become a key political issue over the past forty years and has resulted in the enactment of many different environmental policies. The three essays in this dissertation add to the literature of renewable energy policies and sulfur dioxide emissions trading. The first essay ascertains which state policies are accelerating deployment of non-hydropower renewable electricity generation capacity into a states electric power industry. As would be expected, policies that lead to significant increases in actual renewable capacity in that state either set a Renewables Portfolio Standard with a certain level of required renewable capacity or use Clean Energy Funds to directly fund utility-scale renewable capacity construction. A surprising result is that Required Green Power Options, a policy that merely requires all utilities in a state to offer the option for consumers to purchase renewable energy at a premium rate, has a sizable impact on non-hydro renewable capacity in that state. The second essay studies the theoretical impacts fuel contract constraints have on an electricity generating unit's compliance costs of meeting the emissions compliance restrictions set by Phase I of the Title IV SO2 Emissions Trading Program. Fuel contract constraints restrict a utility's degrees of freedom in coal purchasing options, which can lead to the use of a more expensive compliance option and higher compliance costs. The third essay analytically and empirically shows how fuel contract constraints impact the emissions allowance market and total electric power industry compliance costs. This paper uses generating unit-level simulations to replicate results from previous studies and show that fuel contracts appear to explain a large portion (65%) of the previously unexplained compliance cost simulations. Also, my study considers a more appropriate plant-level decisions for compliance choices by analytically analyzing the plant level decision-making process to

This paper proposes a topic-independent method for automatically scoring essay content. Unlike conventional topic-dependent methods, it predicts the human-assigned score of a given essay without training essays written to the same topic as the target essay. To achieve this, this paper introduces a new measure called MIDF that measures how important and relevant a word is in a given essay. The proposed method predicts the score relying on the distribution of MIDF. Surprisingly, experiments show that the proposed method achieves an accuracy of 0.848 and performs as well as or even better than conventional topic-dependent methods.
This thesis consists of four essays. The first essay looks at pollution taxation under capital mobility, and analyzes the role of pre-commitment by countries to their pollution tax rate. A polluting firm sells its product in two countries, and can locate and produce in a single country or in both countries. Due to the discrete-choice nature of the firm's location problem, the countries' welfare functions are discontinuous in their pollution tax rate. We show that when the countries cannot pre-commit to their pollution tax, the firm can still engender tax competition between them by strategically locating in both the countries. Moreover, pre-commitment pollution taxation may not be welfare improving for the countries, although it always makes the firm better off. The second essay studies the effect of liberalization on corruption. Corruptible inspectors enforce an environmental regulation on firms, and are monitored by an honest regulator. Liberalization not only increases the variety of goods and the marginal utility of accepting a bribe, but also puts pressure on the regulator to curb corruption. The interaction of these two effects can cause corruption to initially increase with liberalization, and then decrease beyond a threshold. Moreover, equilibrium corruption is lower when the regulator is able to pre-commit to her monitoring frequency. The third essay analyzes optimal labeling (information revelation) procedures for hidden attributes of credence goods. Consumers are heterogeneous in their preference for the hidden attribute, and producers can either self-label their products, or have them certified by a third party. The government can impose self or third-party labeling requirements on either the "green" or the "brown" producers. When corrupt producers can affix spurious labels, the government needs to monitor them. A mandatory self-labeling policy is shown to generally dominate mandatory third-party labeling. The fourth essay develops formulas for
This thesis is comprised of three essays which explore selected aspects of demand side energy efficiency policy of International Energy Conservation Codes (IECC). The first essay models the adoption of IECC in the U.S. between 1998 and 2010. An ordered probit model with IECC adoption as the dependent variable is used to test if a set of socio-economics, political, spatial, and environmental factors predict the residential building energy code adoption. The results show that higher energy price, relative political extraction, climate extremes, pollution level, and population growth predict IECC adoption in the sample. The diffusion variable (share of neighbor states with IECC) is shown to have large impacts on the probability of IECC adoption. The next two essays examine the effect of IECC on residential electricity consumption. The second essay investigates the impact of International Energy Conservation Codes (IECC) on per-capita residential electricity consumption for 44 U.S. states from 1981-2008. Applying the pooled mean group (PMG) model developed by Pesaran et al. (1999), and controlling for energy specific demand factors such as: prices, income, heating degree days, and cooling degree days, I find that there is an overall 2% decrease in new residential buildings per-capita electricity consumption in the states which adopted any version of IECC. The new residential buildings per-capita electricity consumption has decreased by about 2.5% and 5% in the states with IECC 2000 and IECC 2003 respectively. The third essay examines the impact of building energy code on the household electricity consumption in three states in U.S. To do so; I construct a pseudo panel using household level data from the American Community Survey (ACS) over the period 2005-2010. By constructing pseudo panel, we are able to track cohorts of relatively homogeneous individuals over time, and control for cohort unobserved heterogeneity that may bias the results of cross sectional estimates

Technological change over the past three decades has altered most of the basic conditions in the electric power industry. Because of technical progress, the dominant paradigm has shifted from the provision of electric power by regulated and vertically integrated local natural monopolies to competition and vertical separation. In the first essay I provide a historical context of the electric industry's power current deregulation debate. Then a dynamic model of induced institutional change is used to investigate how endogenous technological advancements have induced radical institutional change in the generation and transmission segments of the electric power industry. Because the Federal Energy Regulatory Commission (FERC) ordered regulated utilities to provide open access to their transmission networks and to separate their generation and transmission functions, transmission networks have been used more intensively and in much different ways then in the past. The second essay tests experimentally the predictions of neoclassical theory for a radial electric power market under two alternative deregulated transmission institutions: financial transmission rights and physical transmission rights. Experimental evidence presented there demonstrates that an electric power market with physical transmission rights governing its transmission network generates more "right" market signals relative to a transmission network governed by financial transmission rights. The move to a greater reliance on markets for electric power is an idea that has animated sweeping and dramatic changes in the traditional business of electric power. The third essay examines two of the most innovative and complex initiatives of making electric power markets in the United States: California and PJM. As those markets mature and others are made, they must revise their governance mechanisms to eliminate rules that create inefficiency and adopt rules that work efficiently elsewhere. I argue that

A historical essay is presented relating concepts of epilepsy, hysteria, and "possession." The designation "hysteroepilepsy" is placed into the context of combined phenomena in individual subject instances. An association of psychotic states resembling a schizoprenic disorder is indicated as occurring in certain epileptic patients, especially some complex partial seizures (i.e., temporal lobe-psychomotor type). Phenomena of possession may appear within any of these entities. Differential diagnosis now is aided greatly by ulilization of monitoring with combined split screen television viewing and recording of the patient's behavior and the concomitant electroencephalogram. Treatment is directed both medically and toward alleviation of contributing and precipitating psychological and sociological factors.

This dissertation applies techniques from the expanding field of econometrics to the study of contemporary issues in environmental and resource economics. Three essays are offered that aim to generate meaningful policy implications through econometric analyses of the voluminous data recently becoming available to researchers. The first essay examines how overall price, quality and welfare changed as energy efficiency standards in the US became progressively more stringent between 2001-2011. A novel index-the Constant Quality Price Index (CQPI)-is developed to delineate changes in overall price and quality. Results obtained using point-of-sale data from individual clothes washers sold in the US during the period suggest that standards on washing machines have had at worst a negligible effect on consumer welfare, or at best lowered prices and improved quality for washers. The second essay analyzes the relationship between foreign acquisition and aspects of plant-level environmental performance using micro data from the Indonesian Census of Manufacturing. To establish a causal effect of ownership change, a difference-in-differences approach is combined with coarsened exact matching. A total of 264 acquisition cases between 1983-2001 are considered, where an acquired plant is observed at least a year before and three years after undergoing a change in ownership, and for which a carefully selected control plant exists. Results suggest that FDIs can have positive scale and technique effects on the environmental performance of acquired plants. These effects are especially pronounced for small firms and firms that were relatively inefficient prior to acquisition. The third essay analyzes the impact of oil price shocks on the US economy at the individual state level. The study accounts for the endogeneity of changes in crude oil price, differences among states, and spillover effects with neighboring states. Results suggest that the implications of higher oil prices for a
Economic integration is a term used to describe how different aspects between economies are integrated. As economic integration increases, the barriers of trade between markets diminishes. The most integrated economy today, between independent nations, is the European Union and its euro zone. This dissertation consists of three essays which examine consequences of economic integration. The debate over the environmental consequences of free trade is not only quite heated, but also entails significant policy ramifications. Recently, cross-sectional analysis at the country level has made use of exogenous determinants of trade to identify the causal effect of trade on the environment, finding moderate evidence of a beneficial impact of expanded trade on environmental quality. Given the stakes involved, the first essay revisits this finding using subnational data on 'trade' flows across US states and several measures of pollution. Not only does the analysis shed further light on the debate at the international level, but also addresses a heretofore unexamined question: Does greater inter-regional commerce at the subnational level harm the environment? The findings are striking, providing further evidence against a negative environmental impact of trade for the majority of measures analyzed. However, several sources of heterogeneity arise that are noteworthy. The second essay investigates the effect of the euro on trade among EMU members. Using various semi-nonparametric methods based on matching, the results suggest that the euro has a statistical and economic impact on trade. The results show that two countries sharing the euro currency trade somewhere between 9% and 14% more than other country-pairs. In addition, there is no evidence of trade diversion due to the euro. In one strand of research, analysts examine trends in and the determinants of energy usage and intensity. In a second strand, researchers analyze the impact of trade flows on environmental outcomes

Essay I develops a comparative institutional analysis of network access price regulation and "light-handed" regulation. While the former is a specific-agency-based arrangement with higher political influence, the latter is a court-based system. Consequently, the main trade-off between both frameworks reflects the merits of having efficient political and judicial institutions. Price regulation is superior when distributional concerns are irrelevant and information asymmetries are lower. Poorly functioning political systems and high welfare costs of raising funds make price regulation less attractive. Light regulation is more attractive when potential rents are smaller, the monopolist is more risk averse, the judicial system is more efficient, and the threat of government intervention is more credible. The possibility of private transfers makes price regulation more advantageous. Higher information asymmetries among firms makes light-handed regulation more attractive. The main results are consistent with a plausible interpretation of the drastic deregulatory process in New Zealand. Essay II studies the preliminary effects of the deregulation of direct access in the New Zealand's electricity market. A slight improvement in quality standards and an overall efficiency increase took place after two years of deregulation. Retailers were able to successfully enter in large demand, dense areas, with a large proportion of industrial and commercial users, where incumbents were not distributing electricity efficiently. Pricing policies appears to be influenced by market forces (associated to economic and demographic characteristics) as expected in a light regulatory framework. Essay III focuses on the possibility of endogenous sunk costs and the introduction of new products. Firms that exert some monopoly power in one market and introduce a new good whose demand is determined by a broader set of consumers might be forced to change their competing strategies. If the new product

Despite market-based incentives and mandated production, the U.S. cellulosic biofuel industry has been slow to develop. This dissertation explores the economic factors that have limited industry development along with important economic tradeoffs that will be encountered with commercial-scale production. The first essay provides an overview of the policies, potential, and challenges of the biofuel industry, with a focus on cellulosic biofuel. The second essay considers the economics of cellulosic biofuel production. Breakeven models of the local feedstock supply system and biofuel refining process are constructed to develop the Biofuel Breakeven (BioBreak) program, a stochastic, Excel-based program that evaluates the feasibility of local biofuel and biomass markets under various policy and market scenarios. An application of the BioBreak program is presented using expected market conditions for 14 local cellulosic biofuel markets that vary by feedstock and location. The economic costs of biofuel production identified from the BioBreak application are higher than frequently anticipated and raise questions about the potential of cellulosic ethanol as a sustainable and economical substitute for conventional fuels. Program results also are extended using life-cycle analysis to evaluate the cost of reducing GHG emissions by substituting cellulosic ethanol for conventional fuel. The third essay takes a closer look at the economic trade-offs within the biorefinery industry and feedstock production processes. A long-run biomass production through bioenergy conversion cost model is developed that incorporates heterogeneity of biomass suppliers within and between local markets. The model builds on previous literature by treating biomass as a non-commoditized feedstock and relaxes the common assumption of fixed biomass density and price within local markets. An empirical application is provided for switchgrass-based ethanol production within U.S. crop reporting districts
Electricity demand analysis using cointegration and error-correction models with time varying parameters: The Mexican case. In this essay we show how some flexibility can be allowed in modeling the parameters of the electricity demand function by employing the time varying coefficient (TVC) cointegrating model developed by Park and Hahn (1999). With the income elasticity of electricity demand modeled as a TVC, we perform tests to examine the adequacy of the proposed model against the cointegrating regression with fixed coefficients, as well as against the spuriousness of the regression with TVC. The results reject the specification of the model with fixed coefficients and favor the proposed model. We also show how some flexibility is gained in the specification of the error correction model based on the proposed TVC cointegrating model, by including more lags of the error correction term as predetermined variables. Finally, we present the results of some out-of-sample forecast comparison among competing models. Electricity demand and supply in Mexico. In this essay we present a simplified model of the Mexican electricity transmission network. We use the model to approximate the marginal cost of supplying electricity to consumers in different locations and at different times of the year. We examine how costs and system operations will be affected by proposed investments in generation and transmission capacity given a forecast of growth in regional electricity demands. Decomposing electricity prices with jumps. In this essay we propose a model that decomposes electricity prices into two independent stochastic processes: one that represents the "normal" pattern of electricity prices and the other that captures temporary shocks, or "jumps", with non-lasting effects in the market. Each contains specific mean reverting parameters to estimate. In order to identify such components we specify a state-space model with regime switching. Using Kim's (1994) filtering algorithm

Because much of a nurse's work is accomplished through working in groups, nursing students need an understanding of group process as well as opportunities to problem-solve in groups. Despite an emphasis on group activities as critical for classroom learning, there is a lack of evidence in the nursing literature that describes collaborative essay testing as a teaching strategy. In this class, nursing students worked together in small groups to answer examination questions before submitting a common set of answers. In a follow-up survey, students reported that collaborative testing was a positive experience (e.g., promoting critical thinking, confidence in knowledge, and teamwork). Faculty were excited by the lively dialog heard during the testing in what appeared to be an atmosphere of teamwork. Future efforts could include providing nursing students with direct instruction on group process and more opportunities to work and test collaboratively.
John Locke engaged in a systematic study of medicine from the late 1650's. In this period he acquainted himself with the three main competing natural philosophical theories of the time -Galenism, Paracelsianism and Mechanism. He was particularly interested in the work of Sennert, Helmont and Doyle. In 1666, just after the publication of Boyle's The Origine of Formes and Qualities, Locke wrote a short paper entitled Morbus. This paper gave Locke's own view of the nature of disease. Locke went out of his way to criticise Boyle's attempts to give mechanical explanations for biological phenomena. He endorsed Helmont's theory that disease was caused by "ferments" and "Archei" and re-introduced Galenic temperaments as factors of susceptibility in seminal diseases. Locke did not endorse a mechanical corpuscularianism at this stage in his career, when his contact with Boyle was most frequent. Consequently, Locke's espousal of the corpuscular philosophy in the Essay cannot be attributed to Locke's association with Boyle at this time.

This is Part 2 of a transcription of Bentham's manuscript essay on "Paederasty" (1785), Part 1 of which appeared in Vol. 3, No. 4. In Part 1 Bentham argued for the decriminalization of sodomy and opposed the theories of Montesquieu and Voltaire as to its social dangers. In Part 2 Bentham speculates on its causes and alleges that the real reason such behavior is so severely punished is an irrational "antipathy" to pleasure generally and to sexual pleasure in particular. He discusses the danger of blackmail and false accusations and the punishment of lesbian acts, bestiality, and masturbation. Some miscellaneous related notes by Bentham are appended: these deal with religious fears based on the destruction of Sodom, the threat to population, the harshness of English naval law, and other topics.

The first essay of this dissertation, "estimating non-market economic benefits of using biodiesel fuel: a stochastic double bounded approach", is an attempt to incorporate uncertainty into double bounded dichotomous choice contingent valuation. The double bounded approach, which entails asking respondents a follow-up question after they have answered a first question, has emerged as a means to increase efficiency in willingness to pay (WTP) estimates. However, several studies have found inconsistency between WTP estimates generated by the first and second questions. In this study, it is posited that this inconsistency is due to uncertainty facing the respondents when the second question is introduced. The author seeks to understand whether using a follow-up question in a stochastic format, which allows respondents to express uncertainty, would alleviate the inconsistency problem. In a contingent valuation survey to estimate non-market economic benefits of using more biodiesel vs. petroleum diesel fuel in an airshed encompassing South Eastern and Central Ohio, it is found that the gap between WTP estimates produced by the first and the second questions reduces when respondents are allowed to express uncertainty. The proposed stochastic follow-up approach yields more efficient WTP estimates than the conventional follow-up approach while maintaining efficiency gain over the single bounded model. From a methodological standpoint, this study distinguishes from previous research by being the first to implement a double bounded contingent valuation survey with a stochastic follow-up question. In the second essay, "analyzing the effects of civil wars and violent conflicts on food security in developing countries: an instrumental variable panel data approach", instrumental variable panel data techniques are applied to estimate the effects of civil wars and violent conflicts on food security in a sample of 73 developing countries from 1970 to 2002. The number of hungry in
The difficulty of providing adequate protection to the civilian population with some kind of civil defense program is magnified by the technology available in the nuclear age. The United States expanded its civil defense program in the 1950's to include a measure of protection in the event of the explosion of nuclear devices. However, the history of the United States civil defense program has been generally characterized by inadequate funding and little interest at all levels of government. Most recently, the civil defense program has been associated and considered a component of nuclear deterrence. Under the direction of the Federal Emergency Management Agency, the government will rely on crisis relocation as the primary means of protecting the population in the event of a nuclear attack or detonation. This plan envisions that evacuation of the population from high-risk areas to safer host areas. Does crisis relocation provide the country with a credible component to our nuclear deterrence. Do the leaders and citizens have confidence in the nation's ability to protect the civilian population. Have the leaders been completely forthright in preparing the population for the possibility of a nuclear war. These and related issues are discussed in this essay.
The following essay is a review of the literature about the American eugenics movement produced by scholars over the last fifty years. The essay provides an explanation for today's renewed interest in the subject and for why the science of eugenics remains relevant to contemporary society. The essay examines the catalyst to re-examine the eugenics movement, the influence of Darwinian thought upon its development, the political and institutional support for its growth, the relationship between eugenics, sterilization, and sex, and how the twentieth-century promises of the science of better breeding was a precursor to the twenty-first-century promise of genetic engineering.
The essays in this dissertation study information disclosure and environmental policy. The first chapter challenges the longstanding result that firms will, in general, voluntarily disclose information about product quality, in light of the unrealism of the assumption, common to much of the literature, that consumers are identical. When this assumption is relaxed, an efficiency-enhancing role may emerge for disclosure regulation, insofar as it can improve information provision and thus help protect consumers with "moderately atypical" preferences. The paper also endogenizes firms's choice of quality and suggests that disclosure regulation may also raise welfare indirectly, by inducing firms to improve product quality. The second chapter explores the significance of policy-induced technological change (ITC) for the design of carbon-abatement policies. The paper considers both R&D-based and learning-by-doing-based knowledge accumulation, examining each specification under both a cost-effectiveness and a benefit-cost policy criterion. We show analytically that the presence of ITC generally implies a lower profile of optimal carbon taxes, a shifting of abatement effort into the future (in the R&D scenarios), and an increase in the scale of abatement (in the benefit-cost scenarios). Numerical simulations indicate that the impact of ITC on abatement timing is very slight, but the effects on costs, optimal carbon taxes, and cumulative abatement can be large. The third chapter uses a World Bank dataset on Chinese state-owned enterprises to estimate price elasticities of industrial coal demand. A simple coal-demand equation is estimated in many forms, and significant price sensitivity is almost always found: the own-price elasticity is estimated to be roughly -0.5. A cost-function/share-equation system is also estimated, and although the function is frequently ill-behaved, indicating that firms may not be minimizing costs, the elasticity estimates again are large and

This thesis is a collection of three essays which address some empirical applications of long memory processes with specific interest in financial economics of energy futures market. The first essay 'Evidence of Long Memory in the Petroleum Market' studies evidence of long memory in the energy market using daily and weekly futures data. This essay concentrates on the question of interdependence between crude oil futures and the corresponding products. The empirical results provide strong support for long memory in the energy futures market. The cointegrating relations between crude oil and heating oil futures as well as crude oil and unleaded gasoline futures exhibit long memory, whereas the individual series are unit-root. The second essay 'Convenience Yield, Mean Reversion and Long Memory in the Petroleum Market' analyzes convenience yields in the petroleum market. The focus of this essay is the behavior of the spot and futures prices over the long run. The implied convenience yield for petroleum and petroleum products is found to be driven by a nonstationary and mean reverting long memory process. The theoretical implication of this finding is established. It is discussed that this might be attributed to the fact that the market is expecting mean reversion in the spot prices. Furthermore, the volatility process and its relation with the mean process and the corresponding direction of causality have been studied in detail. The third essay 'Long Memory and Conditional Heteroskedasticity, A Monte Carlo Investigation', unlike the first two, looks at the econometrics of the estimators of the long memory process. It evaluates performance of three methods of estimating the parameter of fractionally integrated noise: the exact maximum likelihood estimator (MLE), the quasi maximum likelihood estimator (QMLE), and the GPH under different realizations for variance.

tuneable lasers, generally with the emphasis on understanding the underlying physics rather than accumulating data. He had a highly original mind, which showed both in his choice of research topics and in his method of approach. He did not follow fashion; his instinct for an interesting problem was at odds with the modem policy of direct funding and the identification of "growth areas". His applications for research grants were often unsuccessful, despite his high international standing and integrity. He was never interested in building up a large research team, and had comparatively few research students, but his enthusiasm and commitment to the quality of his science attracted a succession of overseas visitors to his laboratory. Following my own year at the Clarendon, and some subsequent visits both to Oxford and to Reading, there was a continuing strong association between the Clarendon and Otago Physics that continues until today. George Series was the William Evans Visiting Professor to Otago University in 1972. He never lost his interest in the fundamentals of physics inspired by his first researches into the structure of the hydrogen atom; he wrote on the Rydberg constant, the physics of spontaneous emission, and on the fine-structure constant α = e2/hc. He donated a garden seat to St Edmund Hall (Oxford), of which he was a Fellow. On it he placed a plaque* in recognition of the ubiquitous nature of this constant; it almost had magical significance for him. He served physics in many ways outside research. He was for a number of years the Editor of the European Journal of Physics and was also Editor of the Journal of Physics B: Atomic and Molecular Physics, He was also on the Editorial Board of a number of journals. He was elected to Fellowship of a number of physics societies. The Editorial Board of these Memorial Essays dedicate them to George's memory, and to his wife Annette and his family.

.S. Department of Energy's National Laboratories, and provide the first quantitative evidence that technology transfer agreements at the Labs lead to greatly increased rates of innovation spillovers. This chapter also makes a key methodological contribution by introducing a technique to utilize automated text analysis in an empirical matching design that is broadly applicable to other types of social science studies. This work has important implications for how policies should be designed to maximize the social benefits of the $125 billion in annual federal funding allocated to research and development and the extent to which private firms can benefit from technology partnerships with the government. The final chapter of this dissertation explores the effectiveness of international policy to facilitate the deployment of low-emitting energy technologies in developing countries. Together with Joern Huenteler, I examine wind energy deployment in China supported through international climate finance flows under the Kyoto Protocol's Clean Development Mechanism. Utilizing a project-level financial model of wind energy projects parameterized with high-resolution observations of Chinese wind speeds, we find that the environmental benefits of projects financed under the Clean Development Mechanism are substantially lower than reported, as many Chinese wind projects would have been built without the Mechanism's support, and thus do not represent additional clean energy generation. Together, the essays in this dissertation suggest several limitations of energy technology innovation policy and areas for reform. Public funds for energy research and development could be made more effective if decision making approaches were better grounded in available technical expertise and developed in framework that captures the important interactions of technologies in a research and development portfolio. The first chapter of this dissertation suggests a politically feasible path towards this type of

O'Rear, Eric G.
This dissertation encompasses three essays evaluating the impacts of different policies targeting the greenhouse gas (GHG) emissions, fuel demands, etc. of the transportation sector. Though there are some similarities across the three chapters, each essay stands alone as an independent work. The 2010 US EPA MARKAL model is used in each essay to evaluate policy effects. Essay 1 focuses on the recent increases in Corporate Average Fuel Economy (CAFE) standards, and the implications of a "rebound effect." These increases are compared to a carbon tax generating similar reductions in system-wide emissions. As anticipated, the largest reductions in fuel use by light-duty vehicles (LDV) and emissions are achieved under CAFE. Consideration of the rebound effect does little to distort CAFE benefits. Our work validates many economists' belief that a carbon tax is a more efficient approach. However, because the tax takes advantage of cheaper abatement opportunities in other sectors, reductions in transportation emissions will be much lower than what we observe with CAFE. Essay 2 compares CAFE increases with what some economists suggest would be a much more "efficient" alternative -- a system-wide oil tax internalizing some environmental externalities. Because oil taxes are likely to be implemented in addition to CAFE standards, we consider a combined policy case reflecting this. Our supplementary analysis approximates the appropriate tax rates to produce similar reductions in oil demands as CAFE (CAFE-equivalent tax rates). We discover that taxes result in greater and more cost-effective reductions in system-wide emissions and net oil imports than CAFE. The current fuel tax system is compared to three versions of a national vehicle miles traveled (VMT) tax charged to all LDVs in Essay 3. VMT taxes directly charge motorists for each mile driven and help to correct the problem of eroding tax revenues given the failure of today's fuel taxes to adjust with inflation. Results
Murray, Anthony G.
This dissertation consists of three essays examining household energy decisions and behavior. The first essay examines the adoption of energy efficient Energy Star home appliances by U.S. households. Program effectiveness requires that consumers be aware of the labeling scheme and also change their purchase decisions based on label information. The first essay examines the factors associated with consumer awareness of the Energy Star label of recently purchased major appliances and the factors associated with the choice of Energy Star labeled appliances. The findings suggest that eliminating identified gaps in Energy Star appliance adoption would result in house electricity cost savings of $164 million per year and associated carbon emission reductions of about 1.1 million metric tons per year. The second essay evaluates household energy security and the effectiveness of the Low-Income Home Energy Assistance Program (LIHEAP), the single largest energy assistance program available to poor households within the United States. Energy security is conceptually akin to the well-known concept of food security. Rasch models and household responses to energy security questions in the 2005 Residential Energy Consumption Survey are used to generate an energy insecurity index that is consistent with those found in the food insecurity literature. Participating in LIHEAP is found to significantly reduce household energy insecurity score in the index. Further, simulations show that the elimination of the energy assistance safety net currently available to households increases the number of energy insecure house- holds by over 16 percent. The third essay develops a five equation demand system to estimate household own-price, cross-price and income elasticities between electricity, natural gas, food at home, food away from home, and non-durable commodity groups. Household cross-price elasticities between energy and food commodities are of particular importance. Energy price shocks

Morphological skills have previously been found to reliably predict reading skill, including word reading, vocabulary, and comprehension. However, less is known about how morphological skills might contribute to writing skill, aside from its well-documented role in the development of spelling. This correlational study examines whether morphological skill, as measured by a sentence generation task tapping both derivational morphology and meta-syntactic skills, predicts performance on a standardized essay writing task for fifth- and eighth-grade U.S. students (N = 233), after controlling for grade level, comprehension, and writing fluency. Multilevel analyses indicated that morphological skill and writing fluency were each uniquely predictive of essay quality, and this finding was consistent regardless of whether accurate spelling was required in the morphological task. Our results suggest that morphological skills play an important role in writing, as has been previously documented in reading and spelling. PMID:26957783
This dissertation consists of three essays. The first essay is mainly concerned with investigating the risk-responsive behavior of OPEC members. Economic theory suggests that producers respond to the risk of volatile price by lowering production level. In the case of OPEC, the risk of the volatility in the price of crude oil does not seem to be a key determinant in the production decision-making process. Engineering constraints, data frequency, and political consideration may be the main causes of such a result. In the second essay, we tested the presence of the asymmetric adjustment in the cheating behavior as a result of crude oil price shocks. We utilize a set of cointegration and error correction methods that do not assume a linear adjustment to test whether cheaters within OPEC respond more to positive or negative crude oil price shocks. We conclude that cheaters respond more to negative shocks than positive shocks in oil price. The inelastic nature of demand for oil seems to play a crucial role in such asymmetric behavior. When there is a negative price shock, OPEC producers compensate for the loss in revenue by overproducing (i.e. cheat). Yet, if there is a positive shock in the price of crude oil, OPEC producers have less incentive to overproduce because of the inelastic demand for oil. The third essay is concerned with testing for the asymmetric adjustment in gasoline prices in the U.S. We consider a Momentum Threshold Autoregressive (MTAR) process to test for the asymmetric adjustment in all of the possible stages that a gallon of gasoline goes through in order to find the source of asymmetry. Then, we examine the dynamics of gasoline prices using asymmetric error correction models based on the MTAR specifications. We find the asymmetric adjustment present in all stages. The asymmetry in the retail stage seems to be the result of insufficient demand faced by retailers.
The U.S. electric power industry has been going through fundamental restructuring and realignment since the 1990's. Many issues and problems have emerged during the transition, and both economists and engineers have been looking for the solutions fervently. In this dissertation, which consists primarily of three essays, we apply economics theory and techniques to the power industry and address two related issues, transmission investment and financial transmission rights (FTRs). The first essay takes the decentralized perspective and investigates the efficiency attribute of market-based transmission investment under perfect competition. We clarify, for the first time, the nature of the externality created by loop flows that causes transmission investment to be inefficient. Our findings have important implications for better understanding of transmission market design and creating incentives for efficient transmission investment. In the second essay, we define several rules for allocating transmission investment cost within the framework of cooperative game theory. These rules provide fair, stable or efficient cost allocations in theory and are good benchmarks against which the allocation mechanism in practice can be compared and improved upon. In the last essay, we make exploratory efforts in analyzing and assessing empirically the performance of the Midwest independent system operator (MISO) FTR auction market. We reveal some stylized facts about this young market and find that it is not efficient under the risk-neutrality assumption. We also point out and correct the drawbacks in previous related work and suggest about more complete empirical work in future. In all, this dissertation makes both theoretic and empirical analysis of the two hot issues related to the power industry and comes up with findings that have important implications for the development of this industry.

The majority of high-stakes tests from elementary school through postsecondary education include the timed impromptu essay as a measure of writing performance. For adolescents with writing disorders, this type of evaluation often presents a significant barrier. The purpose of the current study was twofold. First, we investigated the influence of handwritten, typed, and typed/edited formats of an expository essay on the quality scores received by students with (n = 65) and without (n = 65) dyslexia. Second, we examined the contribution of spelling, handwriting, fluency, and vocabulary complexity to the quality scores that students with and without dyslexia received on the same writing task. Analyses indicated that vocabulary complexity, verbosity, spelling, and handwriting accounted for more variance in essay quality scores for writers with dyslexia than for their typically achieving peers. Both group and individual student outcomes are reported to better understand the needs of struggling writers with dyslexia. Implications for assessment, instruction, and accommodations are discussed with an eye toward reform efforts that target improved teaching and learning.

Middle school students struggle to explain thermodynamics concepts. In this study, to help students succeed, we use a natural language processing program to analyze their essays explaining the aspects of thermodynamics and provide guidance based on the automated score. The 346 sixth-grade students were assigned to either the critique condition where they criticized an explanation or the revisit condition where they reviewed visualizations. Within each condition, the student was assigned one of two types of tailored guidance based on the sophistication of their original essay. Both forms of guidance led to significant improvement in student understanding on the posttest. Guidance was more effective for students with low prior knowledge than for those with high prior knowledge (consistent with regression toward the mean). However, analysis of student responses to the guidance illustrates the value of aligning guidance with prior knowledge. All students were required to revise their essay as an embedded assessment. While effective, teachers involved in this study reported that revising is resisted by students and does not align with typical, vocabulary-focused classroom writing activities.

The essays in this dissertation explore different environmental and public policy issues relevant to developing countries. Essay I examines household-level survey responses to the question "How willing would you be to pay somewhat higher taxes to the government if you knew the money would be spent to protect the environment and prevent land, water and air pollution?" Specifically, for twelve developing and three developed countries included in the survey, the empirical relationships among willingness to pay for environmental quality, relative household income and national income are investigated. The results indicate that when the effects of household and national income are combined, households with below-average income in low-income countries are less willing to pay for environmental protection than those with above-average income in high-income countries. Furthermore, willingness to pay for environmental protection increases more significantly with relative household income than with national income. Essay II uses data from urban Bolivia to study the determinants of household fuel choice, an important link between deforestation and indoor air pollution in developing countries. In particular, the effects of fixed fuel costs, income growth, and female earned income on household fuel choice are examined. The results imply that reduction in firewood use in developing countries is not likely to occur simply as the result of income growth. The essay discusses possible policy implications based on the results that fixed fuel costs appear to be a deterrent to switching to a cleaner fuel and households with female earned income seem less likely to use firewood than other households. Essay III analyzes the equity implications of the elimination of fuel subsidies in the 1985 Bolivian economic reforms. An analysis of the direct static burden shows that while the elimination of gasoline subsidies was progressively distributed, the elimination of LPG and kerosene subsidies
This paper proposes an alternative content measure for essay scoring, based on the "difference" in the relative frequency of a word in high-scored versus low-scored essays. The "differential word use" (DWU) measure is the average of these differences across all words in the essay. A positive value indicates the essay is using…
Essays are a traditional component of the course requirements in many post-secondary courses. However, the practical and pedagogical disadvantages of essays are significant.

This dissertation consists of three essays that focus on a Bayesian estimation of stochastic cost frontiers for electric generation plants. This research gives insight into the changing development of the electric generation market and could serve to inform both private investment and public policy decisions. The main contributions to the growing literature on stochastic cost frontier analysis are to (1) Empirically estimate the possible efficiency gain of power plants due to deregulation. (2) Estimate the cost of electric power generating plants using coal as a fuel taking into account both regularity restrictions and sulfur dioxide emissions. (3) Compare costs of plants using coal to those who use natural gas. (4) Apply the Bayesian stochastic frontier model to estimate a single cost frontier and allow firm type to vary across regulated and deregulated plants. The average group efficiency for two different types of plants is estimated. (5) Use a fixed effects and random effects model on an unbalanced panel to estimated group efficiency for regulated and deregulated plants. The first essay focuses on the possible efficiency gain of 136 U.S. electric power generation coal-fired plants in 1996. Results favor the constrained model over the unconstrained model. SO2 is also included in the model to provide more accurate estimates of plant efficiency and returns to scale. The second essay focuses on the predicted costs and returns to scale of coal generation to natural gas generation at plants where the cost of both fuels could be obtained. It is found that, for power plants switching fuel from natural gas to coal in 1996, on average, the expected fuel cost would fall and returns to scale would increase. The third essay first uses pooled unbalanced panel data to analyze the differences in plant efficiency across plant types---regulated and deregulated. The application of a Bayesian stochastic frontier model enables us to apply different mean plant inefficiency terms by
Cook, Benjamin R.
The growing concerns about climate change have led policy makers to consider various regulatory schemes designed to reduce the stock and growth of atmospheric CO2 concentrations while at the same time improving energy security. The most prominent proposals are the so called "cap-and-trade" frameworks which set aggregate emission levels for a jurisdiction and then issue or sell a corresponding number of allowances to emitters. Typically, these policy measures will also encourage the deployment of carbon capture and storage (CCS) in geological formations and mature oil fields through subsidies or other incentives. The ability to store CO 2 in mature oil fields through the deployment of CO2 enhanced oil recovery (CO2--EOR) is particularly attractive as it can simultaneously improve oil recovery at those fields, and serve as a possible financial bridge to the development of CO2 transportation infrastructure. The purpose of this research is to explore the impact that a tandem subsidy-tax policy regime may have on bargaining between emitters and sequestration providers, and also to identify oil units in Wyoming that can profitably undertake CO 2--EOR as a starting point for the build-out of CO2 pipelines. In the first essay an economics lab experiment is designed to simulate private bargaining between carbon emitters (such as power plants) and carbon sequestration sites when the emitter faces carbon taxes, sequestration subsidies or both. In a tax-subsidy policy regime the carbon tax (or purchased allowances) can be avoided by sequestering the carbon, and in some cases the emitter can also earn a subsidy to help pay for the sequestration. The main policy implications of the experiment results are that the sequestration market might be inefficient, and sequestration providers seem to have bargaining power sufficient to command high prices. This may lead to the integration of CO2 sources and sequestration sites, and reduced prices for the injectable CO2 purchased by oil
My dissertation focuses on examining the interrelationship among the environment, energy and economic development. In the first essay, I explore the effects of increased uncertainty over future output prices, input costs and productivity levels on intertemporal emission permits trading. In a dynamic programming setting, a permit price is a convex function of each of these three sources of uncertainty. Increased uncertainty about future market conditions increases the expected permit price and causes risk-neutral firms to reduce ex ante emissions to smooth marginal abatement costs over time. Empirical analysis shows that increased price volatility induced by electricity market restructuring could explain 8-11% of the allowances banked during Phase I of the U.S. sulfur dioxide trading program. Numerical simulation suggests that high uncertainty may generate substantial initial compliance costs, thereby deterring new entrants and reducing efficiency; sharp emission spikes are also more likely to occur under industry-wide uncertainty shocks. In the second essay, I examine whether electricity restructuring improves the efficiency of U.S. nuclear power generation. Based on the full sample of 73 investor-owned nuclear plants in the United States from 1992 to 1998, I estimate cross-sectional and longitudinal efficiency changes associated with restructuring, at the plant level. Various modeling strategies are presented to deal with the policy endogeneity bias that high cost plants are more likely to be restructured. Overall, I find a strikingly positive relationship between the multiple steps of restructuring and plant operating efficiency. In the third essay, I estimate the economic impact of China's national land conversion program on local farm-dependent economies. The impact of the program on 14 industrial sectors in Gansu provinces are investigated using an input-output model. Due to regulatory restrictions, the agricultural sector cannot automatically expand or shrink

This essay provides the research and rationale to support the theory that early adolescence is the best time to present an introduction to quantum mechanics. It supports the creation of an integrated thematic unit to be used with students ages 11--14 in an inclusion classroom without limiting the unit to only an inclusion setting. The first section sets forth five problems the unit was written to address. Citing The National Center for Education Statistics 2000 version of The Nation's Report Card, the problems with current practices in science education resulting in poor student performance are presented. References to Project 2061: Science for All Americans help to demonstrate that students with disabilities are seldom considered when physical science curriculum is being developed, supporting the position that equity in science education is necessary, while maintaining challenging subject matter. The problem of the poor quality of many physical science texts is addressed, with an emphasis on the importance of curricular connections. The poor quality of physical science teacher training in many university teacher training courses is discussed, and the nature of the integrated thematic unit as a curriculum design is examined with reference to what is considered the over-emphasis on "reality-based" content to the exclusion of abstract subject matter. Having presented the problems and supporting their validity, the essay then demonstrated how Kids, Quarks, and Quanta specifically addresses each problem. The two and a half year study of Dr. John Hubisz and the committee he formed under The David and Lucille Packard Foundation grant to review and critique the physical science textbooks currently used with early adolescents is often referenced to support both the problems of teacher training and the poor quality of many texts. Recent brain research conducted by researchers of the National Institute of Mental Health is used to support the presentation of more abstract

This dissertation contains two essays on a new innovative pricing mechanism in the electric power industry known as Real Time Pricing (RTP). RTP is a method of pricing electric power wherein at least one component of the price is set at or near levels that reflect the marginal costs of providing power during each time-specific interval. These prices vary in accord with time-specific, incremental supplier costs. RTP allows customers to manage their own bills by adjusting their consumption as spot prices and supplier costs vary, which may amount during a single day from 2 cents to 85 cents for one kilowatt hour (kWh) of usage. Using 1995 data the hypothesis that industrial customers shift their usage patterns of electricity in response to real time prices is tested. To measure customer responsiveness to real time electric rates, econometric techniques are applied to estimate demand elasticities.
Outside of armed conflicts representing nations with forces in uniforms, another kind of war has emerged waged by terrorists. For the past twenty years terrorists have waged war against nations for a variety of reasons. No rules of war govern their conduct nor do they observe any. Methods of combatting terrorism vary from nation to nation. Few nations agree totally on how to combat this form of lawlessness. This essay examines one approach and suggests another. President Reagan's ultimate decision to bomb Libya is examined through a discussion of the events, repercussions of these events, and world opinion of these events that preceded his decision. A harsher, more-controlled and personal approach to combatting terrorism is suggested and discussed.
Jean Rey, a physician from The Bugue, a little town near Bergerac, published, in 1630, a book entitled "Essays" in which he explained the increase of the mass of lead, when it was strongly heated, by the fixation of a part of the air. This revolutionary publication was not received by the European scientists, because the Father Mersenne, "the secretary of learned Europe", was not able to repeat his experiments. Between 1774 and 1775, Pierre Bayen, who was a military apothecary, published his Works concerning the "precipitate per se", for us HgO, showing that when this compound was destroyed by heating, it produced a gas, and that the mass of this gas and the mass of the mercury obtained were equal to the mass of the "precipitate per se". He concluded that the phlogiston theory was contradictory with the results of the experiments. When, later on, Lavoisier published his important article on the increase of the mass of steal when it was heated in the air, he "forgot" to cite the Works of Bayen. In January 1775, Pierre Bayen published a letter in which he mentioned that he had discovered an exemplar of Jean Rey's book and explained that this physician of the 17th century had supposed the explanation that had been proved by Lavoisier. Nicolas Gobet then published a new edition of the "Essays" in 1777, but this new edition became itself quite rare. An inscription pencilled on the book kept by the British Museum pretends that all the exemplars Lavoisier could find were destroyed. It is not rigorous to conclude on a single document, especially when it is not signed, but it is sufficient to induce doubt.

The reliability and validity of using essays for veterinary medical school admissions requires investigation. We explored the reliability and construct validity of a structured essay station in the 2009 admission process at the University of Calgary Faculty of Veterinary Medicine. One hundred three applicants (female=80.6%, male=19.4%; mean age=23.05 years, SD=3.96) participated. Each applicant wrote a one-hour supervised essay (750 words). Essays were rated independently by two randomly assigned raters (n=16). Raters scored essays on four items, each on a five-point anchored scale. Nine essays were scored by all raters to perform a decision study. Generalizability analysis resulted in a reliability coefficient of 0.55. The decision study indicated that three raters and four items produces a G of 0.68. Essay score correlated with interview score (r=0.30, p<0.01) but not with GPA (r=0.05, p=ns). Overall reliability was adequate and higher than what has been reported for unsupervised written submissions. Results from the decision study suggest that three raters with four items provide adequate reliability. Correlations with interviews and grade point average provide evidence of construct validity. A time-limited essay with a clear scoring protocol results in adequate reliability and some validity.

Typically developing writers in fifth (n = 110, M = 10 years 8 months) or seventh (n = 97, M = 12 years 7 months) grade wrote informative, compare and contrast, and persuasive essays for which the content was held constant-two mountains with a history of volcanic eruption. Relevant background knowledge was provided by reading text and showing colorful illustrations to the students before writing each genre. Results showed considerable variability between genre pairs within and across individual writers in content quality, organization quality, and length. Results, which support multiple expository genres, are consistent with prior research showing multiple genres (narrative vs. expository or even within narrative). Results are discussed in reference to the importance of assessing multiple genres in inferring composing expertise as emphasized by Olinghouse and colleagues.
Concerns about climate change, dependence on oil, and unstable gasoline prices have led to significant efforts by policymakers to cut greenhouse gas (GHG) emissions and oil consumption. The transportation sector is one of the principle emitters of CO2 in the US. It accounts for two-thirds of total U.S. oil consumption and is almost entirely dependent on oil. Within the transportation sector, the light-duty vehicle (LDV) fleet is the main culprit. It is responsible for more than 65 percent of the oil used and for more than 60 percent of total GHG emissions. If a significant fraction of the LDV fleet is gradually replaced by more fuel-efficient technologies, meaningful reductions in GHG emissions and oil consumption will be achieved. This dissertation investigates the potential benefits and impacts of deploying more fuel-efficient vehicles in the LDV fleet. Findings can inform decisions surrounding the development and deployment of the next generation of LDVs. The first essay uses data on 2003 and 2006 model gasoline-powered passenger cars, light trucks and sport utility vehicles to investigate the implicit private cost of improving vehicle fuel efficiencies through reducing other desired attributes such as weight (that is valued for its perceived effect on personal safety) and horsepower. Breakeven gasoline prices that would justify the estimated implicit costs were also calculated. It is found that to justify higher fuel efficiency standards from a consumer perspective, either the external benefits need to be very large or technological advances will need to greatly reduce fuel efficiency costs. The second essay estimates the private benefits and societal impacts of electric vehicles. The findings from the analysis contribute to policy deliberations on how to incentivize the purchase and production of these vehicles. A spreadsheet model was developed to estimate the private benefits and societal impacts of purchasing and utilizing three electric vehicle
This dissertation consists of three essays on urban economics. The three essays are related to urban spatial structure change, energy consumption, greenhouse gas emissions, and housing redevelopment. Chapter 1 answers the question: Does the classic Standard Urban Model still describe the growth of cities? Chapter 2 derives the implications of telework on urban spatial structure, energy consumption, and greenhouse gas emissions. Chapter 3 investigates the long run effects of minimum lot size zoning on neighborhood redevelopment. Chapter 1 identifies a new implication of the classic Standard Urban Model, the "unitary elasticity property (UEP)", which is the sum of the elasticity of central density and the elasticity of land area with respect to population change is approximately equal to unity. When this implication of the SUM is tested, it fits US cities fairly well. Further analysis demonstrates that topographic barriers and age of housing stock are the key factors explaining deviation from the UEP. Chapter 2 develops a numerical urban simulation model with households that are able to telework to investigate the urban form, congestion, energy consumption and greenhouse gas emission implications of telework. Simulation results suggest that by reducing transportation costs, telework causes sprawl, with associated longer commutes and consumption of larger homes, both of which increase energy consumption. Overall effects depend on who captures the gains from telework (workers versus firms), urban land use regulation such as height limits or greenbelts, and the fraction of workers participating in telework. The net effects of telework on energy use and GHG emissions are generally negligible. Chapter 3 applies dynamic programming to investigate the long run effects of minimum lot size zoning on neighborhood redevelopment. With numerical simulation, comparative dynamic results show that minimum lot size zoning can delay initial land conversion and slow down demolition and

Spinal epidural space is a real anatomic space located outside the dura mater and within the spinal canal extending from foramen magnum to sacrum. Important contents of this space are epidural fat, spinal nerves, epidural veins and arteries. Due to close proximity of posterior epidural space to spinal cord and spinal nerves, the lesions present with symptoms of radiculopathy and/or myelopathy. In this pictorial essay, detailed anatomy of the posterior epidural space, pathologies affecting it along with imaging pearls to accurately diagnose them are discussed. Various pathologies affecting the posterior epidural space either arising from the space itself or occurring secondary to vertebral/intervertebral disc pathologies. Primary spinal bone tumors affecting the posterior epidural space have been excluded. The etiological spectrum affecting the posterior epidural space ranges from degenerative, infective, neoplastic - benign or malignant to miscellaneous pathologies. MRI is the modality of choice in evaluation of these lesions with CT scan mainly helpful in detecting calcification. Due to its excellent soft tissue contrast, Magnetic Resonance Imaging is extremely useful in assessing the pathologies of posterior epidural space, to know their entire extent, characterize them and along with clinical history and laboratory data, arrive at a specific diagnosis and guide the referring clinician. It is important to diagnose these lesions early so as to prevent permanent neurological complication.

The Strategic Defense Initiative (SDI) is an investigation by scientists, military leaders, and technologists of the feasibility of strategic defenses against ballistic missiles. Whether strategic defense is the way to go in the future remains to be seen. Although the capability of the envisioned layered, ground, and space-based defensive systems is not specifically addressed, the SDI research program's affect on national-security strategy and its formulation is examined. If found to be feasible and cost-effective, SDI will require a drastic change in our military strategy. This essay reviews how that strategy was formulated in the past in terms of a model and how strategic-defense strategy would be used in the future. More importantly, a discussion of how the SDI impacts on present US national strategy and enhances deterrence is presented. Its influence on technology, conventional defense, and arms controls are offered on this evolving strategic concept and the renewed vigor and interest it has provided in strategy formulation.

Zika virus (ZIKV) is a mosquito-borne arbovirus from the Flaviviridae family. It had caused several epidemics since its discovery in 1947, but there was no significant attention to this virus until the recent outbreak in Brazil in 2015. The main concern is the causal relationship between prenatal ZIKV infection and congenital microcephaly, which has been confirmed recently. Moreover, ZIKV may cause other central nervous system abnormalities such as brain parenchymal atrophy with secondary ventriculomegaly, intracranial calcification, malformations of cortical development (such as polymicrogyria, and lissencephaly-pachygyria), agenesis/hypoplasia of the corpus callosum, cerebellar and brainstem hypoplasia, sensorineural hearing-loss, and ocular abnormalities as well as arthrogryposis in the infected fetuses. Postnatal (acquired) ZIKV infection usually has an asymptomatic or mildly symptomatic course, while prenatal (congenital) ZIKV infection has a more severe course and may cause severe brain anomalies that are described as congenital Zika syndrome. In this pictorial essay, we aim to illustrate the prenatal and postnatal neuroimaging findings that may be seen in fetuses and neonates with congenital Zika syndrome, and will discuss possible radiological differential diagnoses. A detailed knowledge of these findings is paramount for an early correct diagnosis, prognosis determination, and counseling of the affected children and families.

Essays on modeling derivative claims. Essay titles: Essay 1. Modeling energy commodity futures: Is seasonality part of it? Essay 2. Modeling corporate liabilities under regime-switching asset volatility
Essay 1. The paper analyzes the price dynamics of two commodity futures prices---crude oil and natural gas. Some of the latest models of commodity prices are tested here---the two-factor model of Schwartz-Smith (2000), which nests other important models developed earlier. The two-factor model includes a mean-reverting short-term deviation and uncertain equilibrium level to which prices gravitate. The Schwartz-Smith two-factor model is the base case model in the paper. The model parameters of the Schwartz-Smith two-factor model are estimated from traded futures on natural gas and crude oil, using the fixed maturity format I create for futures prices. Analysis of the variance structure of natural gas prices suggests seasonality. The model is estimated on seasonally adjusted data. Model-based seasonality approaches are developed---seasonal dummies and a three-factor model with a stochastic seasonality component of log spot prices. The prediction ability of the various parameterized and non-parameterized versions of models with seasonality is compared in-sample and out-of-sample. The volatility functions model, based on principal components extraction from daily data, with seasonality in short-term volatility, seems to have the best forecasting ability, followed by the two-factor model on Kendall-type deseasonalized data and the seasonal dummies specification. Essay 2. This paper contributes to the extant structural model literature by introducing a time-varying risk-shifting barrier, to model asset substitution, and studying its theoretical and empirical implications on corporate credit spreads. Risk-shifting is expected to affect the default component of corporate spreads, because by switching to a higher level of asset volatility, managers precipitate the onset of distress and endogenously alter the probability of default. I test cross-sectionally whether the risk of volatility regime switching, measured by agency cost, is priced in market corporate spreads. The
With rising demographic growth, there is increasing interest in analytical studies that assess alternative policies to provide an optimal allocation of scarce natural resources while ensuring environmental sustainability. This dissertation consists of three essays in applied resource economics that are interconnected methodologically within the agricultural production sector of Economics. The first chapter examines the sustainability of biofuels by simulating and evaluating an agricultural voluntary program that aims to increase the land use efficiency in the production of biofuels of first generation in the state of Alabama. The results show that participatory decisions may increase the net energy value of biofuels by 208% and reduce emissions by 26%; significantly contributing to the state energy goals. The second chapter tests the hypothesis of overuse of fertilizers and pesticides in U.S. peanut farming with respect to other inputs and address genetic research to reduce the use of the most overused chemical input. The findings suggest that peanut producers overuse fungicide with respect to any other input and that fungi resistant genetically engineered peanuts may increase the producer welfare up to 36.2%. The third chapter implements a bioeconomic model, which consists of a biophysical model and a stochastic dynamic recursive model that is used to measure potential economic and environmental welfare of cotton farmers derived from a rotation scheme that uses peanut as a complementary crop. The results show that the rotation scenario would lower farming costs by 14% due to nitrogen credits from prior peanut land use and reduce non-point source pollution from nitrogen runoff by 6.13% compared to continuous cotton farming.

The authors applied Pennebaker's Linguistic Inquiry and Word Count (LIWC) program to autophotographic essays addressing the question, "Who are you?" to test hypotheses about individuality and social connectedness. Specifically, the authors tested whether insight-oriented words would correlate with individuality ratings, defining essays that portray unique persons who creatively explore the self. Second, the authors tested whether connectedness, operationalized by photos of people-touching and self with others, would correlate with social process words. In 164 student photo essays, greater linguistic cognitive complexity characterized individuality, even when controlling for needs for cognition and uniqueness, and verbal intelligence. Connectedness predicted social words. These findings show that autophotography essays do capture complex self-reflective thought and suggest LIWC may be a valuable tool for understanding the expression of individuality and relatedness.

This dissertation consists of three essays. Chapter II considers the question of whether M2 growth can be used to forecast inflation at horizons of up to ten years. A vector error correction (VEC) model serves as our benchmark model. We find that M2 growth does have marginal predictive content for inflation at horizons of more than two years, but only when allowing for cointegration and when the cointegrating rank and vector are specified a priori. When estimating the cointegration vector or failing to impose cointegration, there is no longer evidence of causality running from M2 growth to inflation at any forecast horizon. Finally, we present evidence that M2 needs to be redefined, as forecasts of the VEC model using data on M2 observed after 1993 are worse than the forecasts of an autoregressive model of inflation. Chapter III reconsiders the evidence for a "rockets and feathers" effect in gasoline markets. We estimate an error correction model of gasoline prices using daily data for the period 1985--1998 and fail to find any evidence of asymmetry. We show that previous work suffered from two problems. First, nonstationarity in some of the regressors was ignored, leading to invalid inference. Second, the weekly data used in previous work leads to a temporal aggregation problem, and thus biased estimates of impulse response functions. Chapter IV tests for a forecasting relationship between the volume of litigation and macroeconomic variables. We analyze annual data for the period 1960--2000 on the number of cases filed, real GDP, real consumption expenditures, inflation, unemployment, and interest rates. Bivariate Granger causality tests show that several of the macroeconomic variables can be used to forecast the volume of litigation, but show no evidence that the volume of litigation can be used to forecast any of the macroeconomic variables. The analysis is then extended to bivariate and multivariate regression models, and we find similar evidence to that of the

The body of this dissertation comprises three standalone essays, presented in three respective chapters. Chapter One explores the possibility that local market power contributes to the asymmetric relationship observed between wholesale costs and retail prices in gasoline markets. I exploit an original data set of weekly gas station prices in Southern California from September 2002 to May 2003, and take advantage of highly detailed station and local market-level characteristics to determine the extent to which spatial differentiation influences price-response asymmetry. I find that brand identity, proximity to rival stations, bundling and advertising, operation type, and local market features and demographics each influence a station's predicted asymmetric relationship between prices and wholesale costs. Chapter Two extends the existing literature on the effect of market structure on price dispersion in airline fares by modeling the effect at the disaggregate ticket level. Whereas past studies rely on aggregate measures of price dispersion such as the Gini coefficient or the standard deviation of fares, this paper estimates the entire empirical distribution of airline fares and documents how the shape of the distribution is determined by market structure. Specifically, I find that monopoly markets favor a wider distribution of fares with more mass in the tails while duopoly and competitive markets exhibit a tighter fare distribution. These findings indicate that the dispersion of airline fares may result from the efforts of airlines to practice second-degree price discrimination. Chapter Three adopts a Bayesian approach to the problem of tree structure specification in nested logit modelling, which requires a heavy computational burden in calculating marginal likelihoods. I compare two different techniques for estimating marginal likelihoods: (1) the Laplace approximation, and (2) reversible jump MCMC. I apply the techniques to both a simulated and a travel mode

Joliet Junior College, Joliet, IL offers a one semester introductory astronomy course each semester. We teach over 110 primarily non-science major students each semester. We use proven active learning strategies such lecture tutorials, think-pair-share questions and small group discussions to help these students develop and retain a good understanding of astrophysical concepts. Occasionally, we offer projects that allow students to explore course topics beyond the classroom. We hope that such projects will increase students' interest in astronomy. We also hope that these assignments will help students to improve their critical thinking and writing skills. In Spring 12, we are offering three short individual essay assignments in our face-to-face sections. The essays focus on transits, eclipses and occultations to highlight the 2012 transit of Venus. For the first essay, students will find images of transit and occultation events using the Astronomy Picture of the Day website and describe their chosen events. In addition, students will predict how variations in certain physical and orbital parameters would alter their particular events. The second essay involves transits, eclipses and occultations observed by spacecraft. Students will describe their transit event, their spacecraft's mission, orbital path, how the orbital path was achieved, etc. The third essay deals with transiting exoplanets. Students will choose at least two exoplanets from an exoplanet database, one of which has been discovered through the transit method. This essay will enable students to learn about detecting exoplanets and how they compare with our solar system. Details of the essay assignments and students' reactions to them will be presented at the meeting.
Sweeney, Richard Leonard
This dissertation consists of three essays on the relationship between firm incentives and energy and environmental policy outcomes. Chapters 1 and 2 study the impact of the 1990 Clean Air Act Amendments on the United States oil refining industry. This legislation imposed extensive restrictions on refined petroleum product markets, requiring select end users to purchase new cleaner versions of gasoline and diesel. In Chapter 2, I estimate the static impact of this intervention on refining costs, product prices and consumer welfare. Isolating these effects is complicated by several challenges likely to appear in other regulatory settings, including overlap between regulated and non-regulated markets and deviations from perfect competition. Using a rich database of refinery operations, I estimate a structural model that incorporates each of these dimensions, and then use this cost structure to simulate policy counterfactuals. I find that the policies increased gasoline production costs by 7 cents per gallon and diesel costs by 3 cents per gallon on average, although these costs varied considerably across refineries. As a result of these restrictions, consumers in regulated markets experienced welfare losses on the order of 3.7 billion per year, but this welfare loss was partially offset by gains of 1.5 billion dollars per year among consumers in markets not subject to regulation. The results highlight the importance of accounting for imperfect competition and market spillovers when assessing the cost of environmental regulation. Chapter 2 estimates the sunk costs incurred by United States oil refineries as a result of the low sulfur diesel program. The complex, regionally integrated nature of the industry poses many challenges for estimating these costs. I overcome them by placing the decision to invest in sulfur removal technology within the framework of a two period model and estimate the model using moment inequalities. I find that the regulation induced between 2
James Parkinson’s Essay on the Shaking Palsy (1817) has long been considered the foundational text of the disease which now bears the author’s name. This paper shows how the Essay radically re-formulated a diverse array of human dysmobilities as a “species” of disease. Parkinson incorporated medical observation with a clear focus on patient experience and subjectivity in a deeply affecting narrative, fusing clinical and urban case-descriptions within the genre of a sentimental natural history. His detailed, diagnostic portrayal of the malady recast earlier descriptions of trembling, posture and gait disorder within a new narrative order, simultaneously recruiting reader involvement to the plight of sufferers. Hardly any clinical examination as we know it today undergirds what remains an exemplary account of disciplined medical witness. The Essay demonstrates the potential of case construction and powerful, sympathetic case writing to transform clinical understanding of a complex medical condition of long duration. PMID:25055707
Okwelum, Edson Ogochukwu
This dissertation is comprised of three related essays examining the potential effectiveness of government energy efficiency programs from both the producer and consumer perspectives. The first chapter is based on a paper I coauthored with Corey Lang. In this manuscript, I address the question of whether strategic behavior by consumers could result in the erosion of energy savings in a demand response program. Understanding how the strategic behavior of consumers affects the net benefits from a demand response program has policy implications because of the increasing importance that demand response has come to play in utility load and reliability management during peak times. Using data from a large field experiment in California in 2007, we test the hypothesis that under a technology program, consumers' strategic behavior results in outcomes that are opposite what is obtainable under a program with price incentive or based of behavior. Chapter II is also an empirical study which explores how the preferences of consumers for large and heavy vehicles imposes costs on society in the form of external costs of accident. This chapter looks at how fleet changes in weight distribution due to corporate average fuel economy and consumer demand for heavier vehicles results in fatalities. It is important to understand how consumer behavior affects the accident rates so that one can obtain unbiased estimates of accident costs that go into benefit-cost analysis of the impact of regulations in automobiles. Chapter three addresses how unobserved heterogeneity and sorting affect the estimates of the consumer willingness to pay for reduction in future gasoline costs. This tradeoff is important to policy makers and manufactures because it could help explain why manufacturers fail to adopt technologies for which the fuel savings far outweigh the costs. The remainder of the abstract provides a more detailed outlines of the three essays. Chapter 1 explores strategic behavior by
Oliver, Matthew E.
The natural gas pipeline transportation industry is comprised of a primary market and a secondary market. In the primary market, pipelines sell 'firm' transport capacity contracts to gas traders, local distribution companies, and other parties. The (per unit) secondary market value of transport is rarely comparable to the regulated primary market two-part tariff. When and where available capacity in the secondary market is scarce, its value can far exceed the primary market tariffs paid by firm contract holders, generating scarcity rents. The following essays demonstrate that this phenomenon has predictable effects on natural gas spot prices, firm capacity reservations, the pipeline's capacity construction and expansion decisions, and the economic welfare of producers and consumers at the market hubs connected by the pipeline. Chapter 1 provides a theoretical framework for understanding how pipeline congestion affects natural gas spot prices within the context of the current regulatory environment, and empirically quantifies this effect over a specific regional pipeline network. As available pipeline capacity over a given route connecting two hubs becomes scarce, the spot prices for gas at the hubs are driven apart---a phenomenon indicative of some market friction that inhibits the ability of spot price arbitrage to fully integrate the two prices, undermining economic efficiency. The theoretical component of Chapter 1 illuminates a potential source of this friction: the deregulated structure of the secondary market for gas transportation services. To support and quantify the predictions of the theoretical model, the empirical component demonstrates that the effect of congestion on the secondary market value of transport---the key factor in driving apart spot prices---can be quite strong. Coefficient estimates indicate that dramatic increases in transport costs are likely to result from marginal increases in congestion. This result has important implications because

A diverse student population is a relatively recent feature of the higher education system in the United Kingdom. Consequently, it may be thought that more "traditional" types of assessment based around essay writing skills for science undergraduates may be of decreasing value and relevance to contemporary students. This article describes a study in which the process of feedback on, and associated redrafting of, an essay was closely supervised to improve essay writing skills and subsequent exam performance. The results of this study show that students can significantly improve their learning and academic performance, as assessed by final examination mark, by a process that more closely mimics a "real-world" situation of review and redrafting. Additionally, the data show that students benefit from feedback only when this is used appropriately by the student. The article also discusses the continuing importance and relevance of essay writing skills so that writing, and acting upon feedback to do with that writing, remains an integral part of the process of learning.

National educational organizations have called upon scientists to become involved in K–12 education reform. From sporadic interaction with students to more sustained partnerships with teachers, the engagement of scientists takes many forms. In this case, scientists from the American Society of Human Genetics (ASHG), the Genetics Society of America (GSA), and the National Society of Genetic Counselors (NSGC) have partnered to organize an essay contest for high school students as part of the activities surrounding National DNA Day. We describe a systematic analysis of 500 of 2443 total essays submitted in response to this contest over 2 years. Our analysis reveals the nature of student misconceptions in genetics, the possible sources of these misconceptions, and potential ways to galvanize genetics education. PMID:18245328

We conducted one experimental intervention based on extended contact principles aimed at fostering the formation of cross-group friendships within educational settings. Italian school children took part in a school competition for the best essay on personal experiences of cross-group friendships with immigrants, to be written in small groups. This manipulation was intended to favour the exchange of personal positive cross-group experiences, thus capitalizing on the benefits of extended contact. In the control condition, participants wrote an essay on friendship, without reference to cross-group relations. Results revealed that children who took part in the intervention reported a higher number of outgroup friends 3 months later. This indirect effect was sequentially mediated by pro-contact ingroup and outgroup norms and by outgroup contact behavioural intentions. This study provides experimental evidence that interventions based on extended contact can foster cross-group friendship formation. Theoretical and practical implications of the findings are discussed.

The purpose of this study was to use text mining analysis of early adolescents' online essays to determine their knowledge of global lunar patterns. Australian and American students in grades five to seven wrote about global lunar patterns they had discovered by sharing observations with each other via the Internet. These essays were analyzed for the students' inclusion of words associated with the shape (i.e., phase), orientation and location of the Moon along with words about similarities and differences. Almost all students wrote about shape but fewer wrote about orientation or location. Students infrequently included words about similarities or differences in the same sentence with shape, orientation or location. Similar to studies about children's and adults' lunar misconceptions, it was found that male and female early adolescents also lacked a robust understanding of global lunar patterns.

This qualitative classroom-based study documents one teacher-researcher's response to the "voice" debate in composition studies and to the opposing views expressed by Elbow and Bartholomae. The author uses Bakhtin's principle of dialogism, Hymes's theory of communicative competence, as well as Ivanic's discussion of discoursally constructed identities to reconceptualize voice and to redesign writing instruction in her sixth grade classroom. This study shows how students, by redefining and then acting on that voice pedagogy in terms that made sense to them, shaped the author's understanding of what counts as "voiced" writing in non-narrative discourse. Based on a grounded-theory analysis of the twenty-six sixth graders' argumentative essays in science, the author explains voice, not as a property of writers or of texts, but as a process of "knowing together"---a collaborative, but not entirely congenial, exercise of establishing one's authority by talking with, against, and through other voices on the issue. As the results of this study show, the students' "I-Ness" or authorial presence within their texts, was born in a nexus of relationships with "rivals," "allies" and "readers." Given their teacher's injunctions to project confidence and authority in argumentative writing, the students assumed fairly adversarial stances toward these conversational partners throughout their essays. Exaggerating the terms for voiced writing built into the curriculum, the sixth graders produced essays that read more like caricatures than examples of argumentation. Their displays of rhetorical bravado and intellectual aggressiveness, however offsetting to the reader, still enabled these sixth graders to composed voiced essays. This study raises doubts about the value of urging students to sound like their "true selves" or to adopt the formal registers of academe. Students, it seems clear, stand to gain by experimenting with a range of textual identities. The author suggests that voice

While the benefits of wind generation are well known, some drawbacks are still being understood as wind power is integrated into the power grid at increasing levels. The primary difference between wind generation and other forms of generation is the intermittent, and somewhat unpredictable, aspect of this resource. The somewhat uncontrollable aspect of wind generation makes it important to consider the relationship between this resource and load, and also how the operation of other non-wind generation resources may be affected. The three essays that comprise this dissertation focus on these and other important issues related to wind generation; leading to an improved understanding of how to better plan for and utilize this resource. The first essay addresses the cost of increased levels of installed wind capacity from both a capacity planning and economic dispatch perspective to arrive at the total system cost of installing a unit of wind capacity. This total includes not only the cost of the wind turbine and associated infrastructure, but also the cost impact an additional unit of wind capacity has on the optimal mix and operation of other generating units in the electricity supply portfolio. The results of the model showed that for all wind expansion scenarios, wind capacity is not cost-effective regardless of the level of the wind production tax credit and carbon prices that were considered. Larger levels of installed wind capacity result in reduced variable cost, but this reduction is not able to offset increases in capital cost, as a unit of installed wind capacity does not result in an equal reduction in other non-wind capacity needs. The second essay develops a methodology to better handle unexpected short term fluctuations in wind generation within the existing power system. The methodology developed in this essay leads to lower expected costs by anticipating and planning for fluctuations in wind generation by focusing on key constraints in the system. The

Offshore wind power is an energy resource whose potential in the US has been recognized only recently. There is now growing interest among the coastal states to harness the resource, particularly in states adjacent to the Mid-Atlantic Bight where the shallow continental shelf allows installation of wind turbines using the existing foundation technology. But the promise of bountiful clean energy from offshore wind could be delayed or forestalled due to policy and regulatory challenges. This dissertation is an effort to identify and address some of the important challenges. Focusing on Delaware as a case study it calculates the extent of the wind resource; considers one means to facilitate resource development---the establishment of statewide and regional public power authorities; analyzes possible regulatory frameworks to manage the resource in state-controlled waters; and assesses the use of distributed storage to manage intermittent output from wind turbines. In order to cover a diversity of topics, this research uses a multi-paper format with four essays forming the body of work. The first essay lays out an accessible methodology to calculate offshore wind resource potential using publicly available data, and uses this methodology to access wind resources off Delaware. The assessment suggests a wind resource approximately four times the average electrical load in Delaware. The second essay examines the potential role of a power authority, a quasi-public institution, in lowering the cost of capital, reducing financial risk of developing and operating a wind farm, and enhancing regional collaboration on resource development and management issues. The analysis suggests that a power authority can lower the cost of offshore wind power by as much as 1/3, thereby preserving the ability to pursue cost-competitive development even if the current federal incentives are removed. The third essay addresses the existing regulatory void in state-controlled waters of Delaware
Medical students following a traditional curriculum get few opportunities to engage in activities such as a literature search, scientific writing, and active and collaborative learning. An analytical essay writing activity (AEWA) in physiology was introduced to first-year students. Each student prepared an essay incorporating new research findings with existing knowledge on a medical topic. Students were expected to study on the topic in detail from textbooks as well as from research publications and write a descriptive and critical analysis. This activity would help them to be aware of new developments in the field and understand the complexity and rapidity of changes in the subject. The aim of this study was to learn how students used the AEWA as a learning process. For this purpose, student perceptions were assessed quantitatively and those of the faculty staff were assessed qualitatively. The data from the students showed considerable achievements in the medical database search, scientific writing, group work, and search for new scientific knowledge. The activity was influenced by prior capabilities in computer use, English language knowledge, and writing ability. Resources available at the medical school had a greater influence on the activity. Faculty staff appreciated the quality of the essay while highlighting areas of improvement. The students seemed to be satisfied with the supervisory role of the faculty staff, whereas the staff felt that the students used the supervisors less than expected. The AEWA was a successful activity promoting many aspects of active and collaborative learning. The low availability of books and information and communications technology (ICT) resources, poor internet connection, and insufficient English language skills were probably responsible for the negative feedback on this activity in this resource-deprived environment.

This research investigates the effect of changes in oil prices and oil price volatility on the U.S. stock returns. The first essay tests whether the sign and the size of oil price shocks matter for the U.S. stock returns. The results suggest a linear model provides a good approximation to the response of real stock returns to real oil price innovations. However, this is not the case when the model is specified in terms of the nominal price of crude oil. Using a modified structural VAR to accommodate GARCH-in-Mean errors, the second essay studies the direct effects of oil price uncertainty on the U.S. stock returns at the aggregate and sectoral levels. We also simulate the response of U.S. stock returns to positive and negative oil price shocks, to examine whether the responses to positive and negative shocks are symmetric. Estimation results suggest that there is no statistically significant effect of oil price volatility on the U.S. stock returns. Moreover, the impulse responses indicate that oil price increases and decreases have symmetric effects on the U.S. stock returns. Using high frequency data, the third essay addresses the issue of uncertainty in oil prices and its effect on U.S. stock returns, taking into account the day of the week effect. The results suggest that the-day-of-the-week effect is present in both the mean and volatility equations. The results also show that the U.S. stock market is sensitive to oil price variations not only at the aggregate level but also across some industries, such as chemicals, entertainment, and retail, where uncertainty in oil prices proves to have positive and statistically significant effect.
