The Role Of Environmental Analogs In Identifying Potentially Invasive Woody Plants In Iowa, Mark P. Widrlechner

Journal of the Iowa Academy of Science: JIAS

Americans cultivate a large and diverse range of introduced woody plants as important sources of food and forest products, as well as for urban horticulture, amenity and wildlife plantings, and windbreaks. A small number of these species have become serious pests, disrupting well-established native plant communities or functioning as range and agricultural weeds. More of these species are not serious pests today, but have escaped cultivation and serve as potential sources of future outbreaks. Two other sources of potentially invasive woody plants are found among species that are not or are only rarely cultivated, about which we often know little …

The Devolution Of Managed Care Contractor Duties: Analysis And Implications For Public Policy In Managed Behavioral Health Care, Sara J. Rosenbaum, Anne R. Markus, Joel B. Teitelbaum

Health Policy and Management Issue Briefs

This Issue Brief analyzes the devolution of the legal duties assumed by managed care organizations (MCOs) in their contracts with group purchasers. Specifically, this brief examines the delegation of MCO contractual duties related to member care and services to individual network providers by comparing the language used in master contracts between purchasers and MCOs with the language contained in agreements with network health care providers who serve members covered under the master contract.

Offenders Incarcerated For Crimes Against Juveniles., David Finkelhor, Richard Ormrod

Crimes Against Children Research Center

This study uses data from the 1997 Survey of Inmates in State Correctional Facilities to examine the characteristics of persons incarcerated for victimizing children and youth. This OJJDP Bulletin, part of the Crimes Against Children series, presents a wide range of information pertaining to victimizers of children, including offense characteristics, offender histories, overall trends, and the severity of sentences received by such criminals. Significant differences between offenders incarcerated for crimes against juveniles and offenders imprisoned for crimes against adults are highlighted. Figures and tables illustrate the Survey's major findings.

Poverty Reduction In Nigeria: The Way Forward, Mike I. Obadan

Economic and Financial Review

The description of Nigeria as a paradox by the World Bank (1996) bas continued to be confirmed by events and official statistics in the country. The paradox is - that the poverty level in Nigeria contradicts the country's immense wealth. Among other things, the country is enormously endowed with human, agricultural, petroleum, gas, and large untapped solid mineral resources. Particularly worrisome is that the country earned over USS300 billion from one resource - petroleum - during the last three decades of the twentieth century. But rather than record remarkable progress in national socio-economic development, Nigeria retrogressed to become one of …

Adolescence And Old Age In Twelve Communities, Pranab Chatterjee, Darlyne Bailey, Nina Aronoff

The Journal of Sociology & Social Welfare

This paper disputes the theory of universal stages of development (often called the epigenetic principle) asserted by Erikson (1963; 1982; 1997) and later developed in detail by Newman & Newman (1987, p. 33). It particularly disputes that there are clear stages of adolescence (12-18), late adolescence (18-22), old age (60-75), and very old age (75+). Data from twelve communities around the world suggest that the concept of adolescence is socially constructed in each local setting, and that the concept of late adolescence is totally absent in some communities. Further, the stage of old age (60-75) is much shorter in some …

Csa: Not Just Science Anymore, Carol Tenopir

School of Information Sciences -- Faculty Publications and Other Works

ASK LIBRARIANS WHAT they think of when they hear "Cambridge Scientific Abstracts" and most, not surprisingly, would likely cite bibliographic databases in the sciences. That is probably why Cambridge Scientific Abstracts officially changed its name to CSA to reflect a broadened scope of topics and types of sources.

Part of the, Cambridge Information Group (CIG), CSA now publishes databases and journals on many subjects and provides access to these and other companies' products through its Internet Database Service (IDS). Even librarians who hadn't paid attention to changes at CSA took notice this year when CIG purchased the R.R. Bowker Co.

Electronic Journals: How User Behavior Is Changing, Carol Tenopir, Donald W. King

School of Information Sciences -- Faculty Publications and Other Works

From 1977 through 2001 the authors have conducted a series of studies that examine reading and publishing habits of scientists in both university and non-university settings (including private companies and national laboratories). For the last decade the studies have measured the influence of ejournals on scholarly reading and publishing behaviours. These studies demonstrate that scientists continue to read widely from scholarly journals primarily for research and current awareness. Reading of scholarly articles has increased to approximately 120-13 articles per person per year, with engineers reading fewer journal articles on the average and medical faculty reading more. A growing amount of …

Constraints, Compromises And Choice: Comparing Three Qualitative Research Studies, Julia Connell, Colin Lynch, Peter Waring

The Qualitative Report

Although a number of texts explore social research strategies and methods, most are limited to a basic discussion of such methods and their associated advantages and disadvantages. Few if any, evaluate and compare methods in the context of actual research experiences. This paper endeavours to bridge that gap by reporting the experiences of three researchers working on three separate qualitative studies. All three studies were concerned with investigating the social milieu within organizations. While the research questions were different in each case, all the researchers shared a common goal - to develop explanations for complex social phenomena manifest both internally …

Once Were Science Teachers, John Loughran, Amanda Berry, Deborah Corrigan

The Qualitative Report

This paper explores the development of three pre-service science teacher educators' understandings of some critical incidents in their development of science teachers that has impacted on the manner in which they teach about teaching in a teacher preparation program. The study draws on self-study methodology by situating their reflection on practice within a critical discourse whereby reframing has been important in learning through a reconsideration from particular critical incidents in their high school science teaching experiences. The authors argue that through critical reflection on practice, as illustrated in this paper, that the beginnings of the articulation and documentation of a …

Toward An Understanding Of Acquired Hearing Loss In A Family: Narrative Play Format As A New Voice In Qualitative Methodology, Bruce A. Kent, Brett E. Furlonger, Delwyn A. Goodrick

The Qualitative Report

This study examines how the reality of acquired hearing loss effects one family. Some consideration is given to the medical elements of the condition but the primary concern is with the psychological and social affects of hearing loss. The affects of the loss are revealed, by using systematic introspection in a narrative play format. This writing format is evaluated as the chronology of events, emotions, turning points and coping strategies are revealed.

Building A Typology Of Self-Renewal: Reflection Upon-Life Story Research, Izhar Oplatka

The Qualitative Report

The current paper provides a researcher's account of the life-story method used in a study which aimed to identify patterns of the self-renewal process among women school principals in mid-career. The subjects of this study were 25 elementary school women principals aged between 43 and 52 in Israel. The paper outlines the practical aspects of the life-story method and contributes to our understanding of the consecutive pragmatic ways to implement a life-story method aimed to explore and develop a typology of a yet unknown phenomenon. Further, the ethical implications of doing life-story interview are discussed and presented.

Social Learning Theory And The Influence Of Male Role Models On African American Children In Project 2000, Rhonda Wells-Wilbon, Spencer Holland

The Qualitative Report

This study is an assessment of observational learning commonly known as social learning theory of a group of 55 African American students who are participants in a mentoring program known as PROJECT 2000. From first through sixth grades male role models, who were largely African American, were in the classroom as teacher assistants. At the time of the study all student participants were in fifth grade. An interview was conducted featuring a short open-ended questionnaire. Students in PROJECT 2000 had an opportunity to express their feelings about the male role models that worked with them in their classroom. These interviews …

The Poverty Of Hard Work: Multiple Jobs And Low Wages In Family Economies Of Rural Utah Households, Christina E. Gringeri

The Journal of Sociology & Social Welfare

The combination of paid work and poverty, or near poverty, is a growing problem in the United States, one of which is often accentuated by residence in rural, low-wage communities where underemployment is more prevalent than in metropolitan areas. This paper examines the experiences of sixty rural families with inadequate employment using data from ethnographic interviews with a particular focus on the strategies they use to meet their family's needs in spite of low-wage work.

Subjective Distributions, Itzhak Gilboa, David Schmeidler

Cowles Foundation Discussion Papers

A decision maker has to choose one of several random variables, with uncertainty known distributions. As a Bayesian she behaves as if she knew the distributions. In his paper we suggest an axiomatic derivation of these (subjective) distributions, which is much more economical than the derivations by de Finetti or Savage. They derive the whole joint distribution of all the available random variables.

A Derivation Of Expected Utility Maximization In The Context Of A Game, Itzhak Gilboa, David Schmeidler

Cowles Foundation Discussion Papers

A decision maker faces a decision problem, or a game against nature. For each probability distribution over the state of the world (nature’s strategies), she has a weak order over her acts (pure strategies). We formulate conditions on these weak orders guaranteeing that they can be jointly represented by expected utility maximization with respect to an almost-unique state-dependent utility, that is, a matrix assigning real numbers to act-state pairs. As opposed to a utility function that is derived in another context, the utility matrix derived in the game will incorporate all psychological or sociological determinants of well-being that result from …

Money And The Monetization Of Credit, Martin Shubik

Cowles Foundation Discussion Papers

The relationship between money and credit is discussed in terms of network linkage. Fiat money is the only instrument with the universal recognition of its issuer. Near monies such as bank money and money substitutes such as gasoline credit cards can be classified in terms of their network links. This leads to a way of considering the velocity of money.

Bootstrapping Macroeconometric Models, Ray C. Fair

Cowles Foundation Discussion Papers

This paper outlines a bootstrapping approach to the estimation and analysis of macroeconometric models. It integrates for dynamic, nonlinear, simultaneous equation models the bootstrapping approach to evaluating estimators initiated by Efron (1979) and the stochastic simulation approach to evaluating models’ properties initiated by Adelman and Adelman (1959). It also estimates for a particular model the gain in coverage accuracy from using bootstrap confidence intervals over asymptotic confidence intervals.

Competitive Pooling: Rothschild-Stiglitz Reconsidered, Pradeep Dubey, John Geanakoplos

Cowles Foundation Discussion Papers

We build a model of competitive pooling, which incorporates adverse selection and signalling into general equilibrium. Pools are characterized by their quantity limits on contributions. Households signal their reliability by choosing which pool to join. In equilibrium, pools with lower quantity limits sell for a higher price, even though each household’s deliveries are the same at all pools. The Rothschild-Stiglitz model of insurance is included as a special case. We show that by recasting their hybrid oligopolistic-competitive story into our perfectly competitive framework, their separating equilibrium always exists (even when they say it doesn’t) and is unique.

Penalised Maximum Likelihood Estimation For Fractional Gaussian Processes, Offer Lieberman

Cowles Foundation Discussion Papers

We apply and extend Firth’s (1993) modified score estimator to deal with a class of stationary Gaussian long-memory processes. Our estimator removes the first order bias of the maximum likelihood estimator. A small simulation study reveals the reduction in the bias is considerable, while it does not inflate the corresponding mean squared error.

Asymptotic Theory For Multivariate Garch Processes, F. Comte, Offer Lieberman

Cowles Foundation Discussion Papers

We provide in this paper asymptotic theory for the multivariate GARCH (p,q) process. Strong consistency of the quasi-maximum likelihood estimator (MLE) is established by appealing to conditions given in Jeantheau [19] in conjunction with a result given by Boussama [9] concerning the existence of a stationary and ergodic solution to the multivariate GARCH (p,q) process. We prove asymptotic normality of the quasi-MLE when the initial state is either stationary or fixed.
