Nanotechnology offers new opportunities for the development of novel materials and strategies that improve technology and industry. This applies especially to agriculture, and our previous field studies have indicated that zinc oxide nanoparticles provide promising nano-fertilizer dispersion in sustainable agriculture. However, little is known about the precise ZnO-NP effects on legumes. Herein, 1 mg·L−1 ZnO-NP spray was dispersed on lentil plants to establish the direct NP effects on lentil production, seed nutritional quality, and stress response under field conditions. Although ZnO-NP exposure positively affected yield, thousand-seed weight and the number of pods per plant, there was no statistically significant …

University Rankings: Evidence And A Conceptual Framework, Jonathan G.S. Koppell, Jacob Fowles, H. George Frederickson

Publications from President Jonathan G.S. Koppell

University ranking has high public visibility, the ranking business has flourished, and institutions of higher education have not been able to ignore it. This study of university ranking presents general considerations of ranking and institutional responses to it, particularly considering reactions to ranking, ranking as a self-fulfilling prophecy, and ranking as a means of transforming qualities into quantities. The authors present a conceptual framework of university ranking based on three propositions and carry out a descriptive statistical analysis of U.S. and international ranking data to evaluate those propositions. The first proposition of university ranking is that ranking systems are demarcated …

Background: Heart rate is used as a health biomarker. This aim of this study was to investigate the effects of playing active video games on the heart rate of older adults, in comparison to the heart rate after common table recreational activity.

Methods: An experimental study with 40 participants was conducted: a control group (n=20) participated in common Pokeno® card games; an experimental group (n=20) played WiiTM bowling. The participants’ pre- and post-activity heart rates were measured and compared between and within groups using t-tests.

Results: The findings signified an 11.9% increase (p

Conclusions: The inclusion of active video games …


China And Brazil: Potential Allies Or Just Brics In The Wall?, Anthony Petros Spanakos Jan 2010

China And Brazil: Potential Allies Or Just Brics In The Wall?, Anthony Petros Spanakos

Department of Political Science and Law Faculty Scholarship and Creative Works

Brazil is an increasingly important actor in global governance and for China specifically. Sino-Brazilian relations have deepened considerably but they remain concentrated in areas of trade and investment. There is also considerable overlap in interests between the two countries in other areas, such as diplomatic and political relations. At the same time, China must manage carefully important differences that exist over the enlargement of the UN and the potential challenge to the Brazilian industry.


Why Economic Performance Has Differed Between Brazil And China? A Comparative Analysis Of Brazilian And Chinese Macroeconomic Policy, Fernando Ferrari-Filho, Anthony Petros Spanakos Jun 2009

Why Economic Performance Has Differed Between Brazil And China? A Comparative Analysis Of Brazilian And Chinese Macroeconomic Policy, Fernando Ferrari-Filho, Anthony Petros Spanakos

This paper addresses a specific question: why has China grown so rapidly and Brazil not? To answer this question, it (i) establishes the basis for comparison between China and Brazil by contextualizing these countries within the BRICs concept, and (ii) presents a comparative analysis of Brazilian and Chinese reforms focusing only on the issue of macroeconomic policy, especially the monetary and exchange rate regimes, and its effect on growth.


Can Non-State Certification Systems Bolster State-Centered Efforts To Promote Sustainable Development Through The Clean Development Mechanism, Jonathan G.S. Koppell, Kelly Levin, Benjamin Cashore Jan 2009

Can Non-State Certification Systems Bolster State-Centered Efforts To Promote Sustainable Development Through The Clean Development Mechanism, Jonathan G.S. Koppell, Kelly Levin, Benjamin Cashore

Publications from President Jonathan G.S. Koppell

Increasing economic globalization has coincided with the emergence and escalating influence of non-state actors and organizations in domestic and international policymaking, from shaping policy agendas to promoting private authority. The latter phenomenon has arisen, at least in part, from a critique of states' failures to adopt effective and enduring environmental policies. Rather than contest "command and control" institutions, non-state strategies embrace market approaches built around incentives and price mechanisms. Several forms of non-state authority have emerged, including corporate social responsibility, provision of information through labeling, and self-reporting.

How does vote intention in presidential elections vary according to the economic conditions of a country, especially indicators of the financial market? Does the state of the economy, both its fundamentals as well as capital market, affect variation in candidates’ percentage of vote intention in national polls? This paper tests how economic indicators influence vote intention in presidential elections in two emerging markets: Brazil and Mexico. The presidential elections of 1994, 1998, 2002, and 2006 in Brazil and 2000 and 2006 in Mexico are analyzed using all poll returns for each electoral period and corresponding economic data. The paper finds …

This paper does not aim to dispute that Brazil would benefit from reforms in any or all of these areas. Rather, the paper offers a skeptical perspective on reform menus and proposes an alternative explanation for the faster growth of Brazil’s peers India and China2. The paper begins by introducing (section 1) the idea of the BRICs countries, to establish the basis for comparisons of most similar cases. It then surveys the results of a generation of Washington Consensus era growth (section 2). Although there is a considerable amount of divergence over what causes growth, it seems that something approaching …

Reform In Lieu Of Change: Tastes Great, Less Filling, Jonathan G.S. Koppell Jan 2006

Reform In Lieu Of Change: Tastes Great, Less Filling, Jonathan G.S. Koppell

Publications from President Jonathan G.S. Koppell

In this response to Light, Koppell argues that the increasing frequency of reform may reflect Congress's inability to make significant changes to the substance of entrenched government programs. Moreover, he observes that the more profound evolution in government has been the movement toward the market-based provision of services, which has created a demand for new competencies in the public sector.

Context: Despite drops in U.S. teenage birthrates, questions continue to arise about how best to reduce the country's adolescent birthrate. School-based programs continue to be considered one of the best ways to reach adolescents at risk of early sexual activity.

Methods: A total of 312 students completed a pretest, a posttest and a follow-up one year after the posttest: 125 who had participated in a 3-4-month-long abstinence-based small-group intervention led by trained social workers, and 187 in a comparison group that received no special services.

Results: There were few significant differences between the intervention and comparison groups at posttest. At …


The Challenge Of Administration By Regulation: Preliminary Findings Regarding The U.S. Government's Venture Capital Funds, Jonathan G.S. Koppell Oct 1999

The Challenge Of Administration By Regulation: Preliminary Findings Regarding The U.S. Government's Venture Capital Funds, Jonathan G.S. Koppell

Publications from President Jonathan G.S. Koppell

This article assesses the ability of elected officials to control public policy as implemented by public/private hybrid organizations, specifically, government venture capital funds. The study reveals greater control over OPIC investment funds than Enterprise Funds despite the existence of more traditional administrative tools of control for Enterprise Funds. This finding suggests that the regulatory infrastructure for hybrid organizations is more determinative of control than the existence (or lack) of traditional administrative control tools. Thus the challenge of hybrid government centers on the development of regulation as a substitute for administration.
