Mapping Selective Logging In Mixed Deciduous Forest: A Comparison Of Machine Learning Algorithms, Christopher D. Lippitt, John Rogan, Zhe Li, J. Ronald Eastman, Trevor G. Jones

Geography

This study assesses the performance of five Machine Learning Algorithms (MLAS) in a chronically modified mixed deciduous forest in Massachusetts (USA) in terms of their ability to detect selective timber logging and to cope with deficient reference datasets. Multitemporal Landsat Enhanced Thematic Mapper-plus (ETM+) imagery is used to assess the performance of three Anificial Neural Networks - Multi-Layer Perceptron, ARTMAP, Self-Organizing Map, and two Classification Tree splitting algorithms: gini and entropy rules, MLA performance evaluations are based on susceptibility to reduced training set size, noise, and variations in the training set, as well as the operability/transparency of the classification process. …

Flow-Performance Relationship And Tournament Behavior In The Mutual Fund Industry, Baoling Ma

Dissertations and Theses Collection (Open Access)

In this paper, we interpret the flow-performance relationship as an incentive scheme implicitly given to mutual fund managers by mutual fund investors. We show that the flow-performance relationship varies not only with economic activity but also across fund attributes. We provide evidence that the degree of convexity of the flow-performance relationship has a positive effect on the magnitude of tournament behavior. Different from the conventional tournament hypothesis, we show that although the convexity of the flow-performance relationship does produce implicit incentives for fund managers to modify risk-taking behavior as a function of their prior performance, whether or not the mid-year …

Offshore Financial Havens: Their Role In International Capital Flows, Zhixiang Sun

Dissertations and Theses Collection (Open Access)

The purpose of this paper is to study the role of offshore financial havens in international capital flows. We examine the effects of being a tax haven, a money laundering centre or an offshore financial centre (OFC), which often overlap. We want to see whether these places are used as entrepots (which means temporary storage for funds) or as investment places or both. We mainly use two complementary data sets: bilateral cross-border asset holding and financial intermediation. One is a stock variable and the other one is a flow variable. We apply the gravity model to bilateral cross-border asset holding …

Stock Markets And Income Inequality: A Cross-Country Study, Elizabeth Mathew

Dissertations and Theses Collection (Open Access)

This paper conducts a comprehensive analysis to understand how stock market ratios affect net income inequality. The study of how finance impacts income distribution is relevant as the income distribution of a nation influences savings decisions, resource allocation, innovation incentives and public policy and hence impacts the process of economic development. Using a cross-sectional data set of 68 countries and panel data set of 61 countries from 1975 to 2005, I apply cross-sectional OLS and panel regressions to look at how stock market size, liquidity, and activity impact income inequality. While stock market size is found to strongly impact income …

Test For Infinite Variance In Stock Returns, Xian Ning Yan

Dissertations and Theses Collection (Open Access)

The existence of second order moment or the finite variance is a commonly used assumption in financial time series analysis. We examine the validation of this condition for main stock index return series by applying the extreme value theory. We compare the performances of the adaptive Hill's estimator and the Smith's estimator for the tail index using Monte Carlo simulations for both i.i.d data and dependent data. The simulation results show that the Hill's estimator with adaptive data-based truncation number performs better in both cases. It has not only smaller bias but also smaller MSE when the true tail index …

Adaptive Estimation Of Autoregressive Models With Time-Varying Variances, Ke-Li Xu, Peter C. B. Phillips

Research Collection School Of Economics

Stable autoregressive models are considered with martingale differences errors scaled by an unknown nonparametric time-varying function generating heterogeneity. An important special case involves structural change in the error variance, but in most practical cases the pattern of variance change over time is unknown and may involve shifts at unknown discrete points in time, continuous evolution or combinations of the two. This paper develops kernel-based estimators of the residual variances and associated adaptive least squares (ALS) estimators of the autoregressive coefficients. Simulations show that efficiency gains are achieved by the adaptive procedure.

Refined Inference On Long Memory In Realized Volatility, Peter C. B. Phillips, Offer Lieberman

Research Collection School Of Economics

There is an emerging consensus in empirical finance that realized volatility series typically display long range dependence with a memory parameter around 0.4 (Andersen et al., 2001; Martens et al., 2004). The present article provides some illustrative analysis of how long memory may arise from the accumulative process underlying realized volatility. The article also uses results in Lieberman and Phillips (2004, 2005) to refine statistical inference about by higher order theory. Standard asymptotic theory has an error rate for error rejection probabilities, and the theory used here refines the approximation to an error rate of. The new formula is independent …

Target Saving In An Overlapping Generations Model, Ashok S. Guha, Brishti Guha

Research Collection School Of Economics

We examine a model in which the utility function has been engineered so that it is optimal for consumers to aim for a fixed target level of retirement resources. In this case consumption displays excess sensitivity to current income as well as perfect old age insurance. In an overlapping generations model, this leads naturally to multiple and unstable equilibria. Under static expectations, it also leads to a well-defined dynamics, including possible historical traps, implosions involving ever-diminishing capital stock and ever-increasing interest rates, and the feasibility of optimal one-time interventions.

Balancing Competing Interests In Bankruptcy: Discharge By Certificate Of The Official Assignee In Singapore, S. Chandra Mohan

Research Collection Yong Pung How School Of Law

After more than a hundred years, Singapore made major reforms to its bankruptcy laws in 1995. These changes attracted considerable public interest, with the Government taking pains to emphasise that the new law was designed to strike a balance between the interest of the debtor, the creditor and society. The greatest scrutiny of the provisions, to determine whether in law and in practice the competing interests of debtors and creditors could effectively be balanced, was in respect of the discharge provisions. In this article, the writer, who was then the Official Assignee, discusses how the novel remedy of discharge by …

Civil Liabilities For False Or Misleading Statements Made By Listed Companies To The Securities Markets In Singapore, Wai Yee Wan

Research Collection Yong Pung How School Of Law

This article examines the scope and efficacy of the civil remedies available to investors against listed companies which have made false or misleading statements in the secondary securities market in Singapore, both at common law and the statutory compensation scheme under the Securities and Futures Act. It argues that there are a number of limitations faced by such investors in bringing claims founded in tort law against the listed companies. While the statutory compensation scheme attempts to improve the position of investors, there are a number of deficiencies in the scheme the most significant of which is the ceiling on …

The Asean Charter As "Legs To Go Places": Ideational Norms And Pragmatic Legalism In Community Building In Southeast Asia, Eugene K. B. Tan

Research Collection Yong Pung How School Of Law

The Charter of the Association of Southeast Asian Nations (ASEAN) has been hailed as a legal instrument that would integrate the ten constituent members as a community and a regional organization. Ostensibly, the Charter has three strategic thrusts in support of the vision of the ASEAN Community. The first is to formalize ASEAN as an institution while streamlining its decision-making processes. Secondly, the Charter seeks to strengthen ASEAN institutions. Thirdly, it seeks to establish mechanisms to monitor compliance and settle disputes. The article considers the extent to which the Charter will help ASEAN achieve its aims. This is especially pertinent …

Breast Health Behavior Among Lesbians: The Role Of Health Beliefs, Heterosexism, And Homophobia, Dana Dehart

Faculty and Staff Publications

The Health Belief Model was used as a conceptual framework for exploring how health beliefs and perceptions of heterosexism and homophobia in health care relate to lesbians' breast health behaviors, including use of breast exams and mammograms, visits to health care providers, and use of complementary/alternative care. A total of 173 exclusively homosexual women completed survey measures assessing health beliefs, experiences of heterosexism/homophobia, and health maintenance behaviors as these related to breast health. Findings indicated that women perceived heterosexism and homophobia from providers to influence the amount of discussion they had with providers and, to a lesser extent, care received, …

The American Public's View Of Congress, John R. Hibbing, Christopher W. Larimer

Department of Political Science: Faculty Publications

Congress has long been unpopular with the American public, with approval numbers above fifty percent serving as the exception rather than the norm. In this essay we argue that such disapproval stems not from calculated reaction to policy outcomes or partisan attachments. Rather, people tend to disapprove of Congress for exactly the thing it was designed to be: an open and deliberative lawmaking body. The more Congress does its job, the more the public tends to disapprove.

Communication And The Knowable Community, Bonnie Brennen

College of Communication Faculty Research and Publications

This essay draws on Raymond Williams's concept of a knowable community in an effort to understand the myriad of connections that exist between individuals and society. Williams, who sees communication and community as synonymous, suggests that a knowable community may ultimately emerge through the process of communication and that in the discovery of connections between individuals and society, an understanding of historically specific patterns may be shown. This essay also discusses an oral history project with journalists who worked for Gannett in the 1960s as an example of an emerging knowable community that questioned traditional notions of community and challenged …

Smoking Cessation: Why Do Smokers Fail?, Joyce M. Wolburg

College of Communication Faculty Research and Publications

Purpose:

The purpose of this article is to probe three explanations for the difficulty that cigarette smokers have in quitting: the addictive nature of the product; the failure to deliver messages with effective quit strategies; and the resistance to enacting smoking bans in bars and restaurants. It aims to argue that the latter two issues result in misplaced marketing.

Design/methodology/approach:

This article examines data from published research, interviews with smokers who have successfully quit, and government statistics to have a clearer picture of the issues.

Findings:

Smokers are exposed to anti‐smoking messages created to discourage youth from starting to smoke, …

Live Interactive Group-Specific Normative Feedback Reduces Misperceptions And Drinking In College Students: A Randomized Cluster Trial, Joseph W. Labrie, Justin F. Hummer, Clayton Neighbors, Eric R. Pedersen

Heads Up!

This research evaluated the efficacy of a live and interactive group-specific normative feedback intervention designed to correct misperceptions of alcohol-related group norms and subsequently reduce drinking behavior. Campus organizations (N = 20) containing 1,162 college students were randomly assigned to intervention or assessment-only control conditions. Participants in the intervention condition attended an intervention during their organization’s regular standing meeting. Data were gathered in vivo using computerized handheld keypads into which participants entered personal responses to a series of alcohol-related questions assessing perceptions of normative group behavior as well as actual individual behavior. These data were then immediately presented in graphical …

Do Firms Have Short Memories? Evidence From Major League Baseball, Andrew Healy

Economics Faculty Works

When deciding what salary to offer an employee, a firm needs to predict that employee’s future productivity. One piece of information that a firm can use to predict productivity is the employee’s past performance record. Classical theory predicts that firms will effectively use the available information to choose an appropriate salary offer. Evidence from baseball contracts indicates, however, that memory-based biases influence salary offers. Consistent with insights from psychology and behavioral economics, salaries are affected too much by recent performance compared with past performance. All organizations do not suffer equally from short memories. The teams that achieve the most with …

The Moral High Ground: An Experimental Study Of Spectator Impartiality, James Konow

Economics Faculty Works

This paper proposes and tests an empirical model of impartiality, inspired by Adam Smith (1759), that is based on the moral judgments of informed third parties (or spectators). The model predicts that spectatorship produces properties widely considered desirable in both the normative and descriptive literature of philosophy and the social sciences, namely, unbiasedness and consensus. This informs a vignette experiment that elicits moral judgments about real world policy issues while varying the information conditions (relevant and irrelevant information) and roles (spectator and stakeholder) of respondents across treatments. The results indicate that spectator views are unbiased, and that relevant information reduces …

Michel Foucault Meets Gary Becker: Criminality Beyond Discipline And Punish, Andrew Dilts

Political Science and International Relations Faculty Works

Among the numerous reasons why Discipline and Punish continues to be read and to shape the contours of criminology, sociology, political theory, and philosophy, is its attention to the development of criminal subjectivity. The ascendancy of the disciplinary age brought about the “fabrication” of the delinquent as a by-product of the discursive needs of the penitentiary technique and the requirements of the juridical law. The figure of the delinquent comes into existence both historically and theoretically at the intersection between discursive orders to manage the contradictions between them, providing a suitable subject for both the court and the penitentiary. The …

Discipline, Security And Beyond: A Brief Introduction, Andrew Dilts

Political Science and International Relations Faculty Works

Discipline and Punish shattered the way many of us thought about punishment and modern society and, for many years, served as one leading optic through which we analyzed penal practices and institutions. The book functioned as a quintessential work in critical theory: it lifted the veil from our eyes, it enlightened us, it fundamentally changed the way we understood contemporary punishment practices. Michel Foucault had shown the lie: we were not punishing less or in a more civilized manner, it turns out, we were punishing better. Our cherished enlightenment thinkers had not tamed punishment, they had perfected it—and this raised …
