Snow parameters from Nimbus-6 electrically scanned microwave radiometer

Two sites in Canada were selected for detailed analysis of the ESMR-6/ snow relationships. Data were analyzed for February 1976 for site 1 and January, February and March 1976 for site 2. Snowpack water equivalents were less than 4.5 inches for site 1 and, depending on the month, were between 2.9 and 14.5 inches for site 2. A statistically significant relationship was found between ESMR-6 measurements and snowpack water equivalents for the Site 2 February and March data. Associated analysis findings presented are the effects of random measurement errors, snow site physiolography, and weather conditions on the ESMR-6/snow relationship

"Government Outlays, Economic Growth and Unemployment: A VAR Model"

This paper examines the dynamic effects of government outlays on economic growth and the unemployment rate. Using vector autoregression and data from twenty OECD countries over three recent decades, we found: (1) positive shocks to government outlays slow down economic growth and raise the unemployment rate; (2) different types of government outlays have different effects on growth and unemployment, with transfers and subsidies having a larger effect than government purchases; (3) causality runs one-way from government outlays to economic growth and the unemployment rate; (4) the above results are not sensitive to how government outlays are financed.government outlays, economic growth, unemployment rate, vector autoregression, Granger causality

The Role of Behavioral Dynamics in Determining the Patch Distributions of Interacting Species

The effect of the behavioral dynamics of movement on the population dynamics of interacting species in multipatch systems is studied. The behavioral dynamics of habitat choice used in a range of previous models are reviewed. There is very limited empirical evidence for distinguishing between these different models, but they differ in important ways, and many lack properties that would guarantee stability of an ideal free distribution in a single-species system. The importance of finding out more about movement dynamics in multispecies systems is shown by an analysis of the effect of movement rules on the dynamics of a particular two-species–two-patch model of competition, where the population dynamical equilibrium in the absence of movement is often not a behavioral equilibrium in the presence of adaptive movement. The population dynamics of this system are explored for several different movement rules and different parameter values, producing a variety of outcomes. Other systems of interacting species that may lack a dynamically stable distribution among patches are discussed, and it is argued that such systems are not rare. The sensitivity of community properties to individual movement behavior in this and earlier studies argues that there is a great need for empirical investigation to determine the applicability of different models of the behavioral dynamics of habitat selection

A Review and Meta-Analysis of Age-Based Stereotype Threat: Negative Stereotypes, Not Facts, Do the Damage.

Stereotype threat effects arise when an individual feels at risk of confirming a negative stereotype about their group and consequently underperforms on stereotype relevant tasks (Steele, 2010). Among older people, underperformance across cognitive and physical tasks is hypothesized to result from age-based stereotype threat (ABST) because of negative age-stereotypes regarding older adults’ competence. The present review and meta-analyses examine 22 published and 10 unpublished articles, including 82 effect sizes (N = 3882) investigating ABST on older people’s (Mage = 69.5) performance. The analysis revealed a significant small-to-medium effect of ABST (d = .28) and important moderators of the effect size. Specifically, older adults are more vulnerable to ABST when (a) stereotype-based rather than fact-based manipulations are used (d = .52); (b) when performance is tested using cognitive measures (d = .36); and (c) occurs reliably when the dependent variable is measured proximally to the manipulation. The review raises important theoretical and methodological issues, and areas for future research. (PsycINFO Database Record (c) 2015 APA, all rights reserved

Deregulation for Development: A Tale of Two States

Economic stress led South Dakota and Delaware in the early 1980’s to eliminate their usury laws and enact other enabling legislation in an effort to attract a new industry and new jobs to their states. Sufficient time has now elapsed to assess the success of the policies adopted by these two states. Evidence suggests that both states benefited from their deregulatory actions but in different ways. These successful deregulations provide an important lesson for state-level authorities responsible for determining the regulatory environment.Regional Development, Deregulation, State Government Public Policy

The Expansion of Fishery Jurisdiction: Fishery Interests and Congressional Voting

The Magnuson Fishery Conservation and Management Act of 1976 greatly broadened the scope of U.S. fishery regulation. While the act contained a variety of features, its primary and certainly most controversial provision expanded the regulated fishing zone from 12 to 200 miles. This paper identifies the primary gainers and losers from the act and assesses their roles in influencing the legislative outcome. The voting behavior of congressional representatives is analyzed by multivariate probit analysis in order to quantify the influences of the major lobbying groups.Environmental Economics and Policy, International Relations/Trade, Political Economy, Resource /Energy Economics and Policy,
