It's who you are and what you do: explaining the IT industry wage premium

The information technology (IT) boom dramatically boosted the rapid growth of the U.S. economy during the 1990s, contributing 1.4 percentage points of the 4.6 percent national average real gross domestic product growth from 1996 to 2000. As the IT boom went bust in 2001, however, the IT sector’s influence on the economy dwindled. ; But a lingering effect of the IT boom may still be apparent in the wages of IT workers. This article explores the extent to which variations in wages between IT-producing and non-IT industries can be accounted for by differences in wages paid to IT-related occupations. ; Using data for 1996 to 2002 from the Current Population Survey’s Earner Study, the authors study a sample of more than 845,000 U.S. workers aged eighteen to sixty-four. The sample is categorized according to individuals’ primary job and is divided into nine industry groups—three IT-related and six non-IT-related. ; The analysis shows that the average wage of IT occupations is greater than for non-IT occupations irrespective of industry. Individual worker characteristics such as years of education may account for some of this wage differential. But even after such characteristics and occupational differences are controlled for, workers in IT-producing industries still enjoy a wage premium over workers in other sectors.

A review of Nyoongar responses to severe climate change and the threat of epidemic disease—Lessons from their past

Nyoongar people have lived in the South West of Western Australia for at least 50,000 years. During that time, they experienced significant climate change, including wide variations in temperature and rainfall, and hundreds of metres’ difference in sea levels. Nyoongar people have a long memory, and climate change is described in their stories and in the knowledge they hold about how life was lived in earlier times. There are artifacts and places that have been manipulated to be productive despite severe drought. COVID-19 disrupted the writing of this article, and the authors felt it appropriate to include Nyoongar responses to the threat of epidemic disease brought by Europeans early in their settlement of the area. This review collates existing material generated through Koodjal Jinnung (two-way seeing), a research method that incorporates traditional knowledge and contemporary social and natural sciences about Nyoongar history, to create a description of the resiliency of Nyoongar people under threat from climate change. The article identifies key values and resilience factors underpinning the successful implementation of behavioural and technological mechanisms to negotiate severe climate change and the threat of epidemic disease

Selecting Content using Second Screen Devices

Disclosed herein is an improved mechanism for selecting content using second screen devices. The system can pair a second screen mobile device with a media presentation device, where the system can begin presenting a first media content item on the media presentation device using a first media content service. The system can then present, on the second screen mobile device, a user interface that indicates a group of available media content services and corresponding available media content items. The system can receive, at the second screen mobile device, a selection of a second media content item associated with a second media content service. In response to receiving the selection of the second media content item associated with the second media content service, the system can cause the media presentation device to switch to presenting the selected second media content item using the second media content service

Determining barriers for establishing an ideal optometric practice

238 optometrists representing the graduating classes of 1991, 1996, and 1998 from Pacific University College of Optometry were surveyed to determine potential barriers to establishing their ideal practice. 96 optometrists (40%) responded to the survey, representing 14 different modes of practice. Overall, the number one barrier for Pacific graduates was debt load with 92% of optometrists agreeing. Other significant barriers were start up costs, (87% agreeing), low initial salary (86%), lack of savings (88%), and lack of business education (87%). Some interesting barrier trends also evolved from this survey. Notably, lack of business education has become less of a barrier when comparing responses from 1991, 1996, and 1998. Competition in the optometric/ophthalmologic market had become a greater barrier for 1998 graduates compared to graduates of 1996, and 1991. Qualifying for insurance plans and finding a suitable practice location have also become emerging barriers for 1998 graduates as compared to graduates from 1991 and 1996. The survey also inquired about annual income, future prospects for the field of optometry, what keeps optometrists enthusiastic about the profession and the possibility of doing it all over again

NMME Monthly / Seasonal Forecasts for NASA SERVIR Applications Science

This work details use of the North American Multi-Model Ensemble (NMME) experimental forecasts as drivers for Decision Support Systems (DSSs) in the NASA / USAID initiative, SERVIR (a Spanish acronym meaning "to serve"). SERVIR integrates satellite observations, ground-based data and forecast models to monitor and forecast environmental changes and to improve response to natural disasters. Through the use of DSSs whose "front ends" are physically based models, the SERVIR activity provides a natural testbed to determine the extent to which NMME monthly to seasonal projections enable scientists, educators, project managers and policy implementers in developing countries to better use probabilistic outlooks of seasonal hydrologic anomalies in assessing agricultural / food security impacts, water availability, and risk to societal infrastructure. The multi-model NMME framework provides a "best practices" approach to probabilistic forecasting. The NMME forecasts are generated at resolution more coarse than that required to support DSS models; downscaling in both space and time is necessary. The methodology adopted here applied model output statistics where we use NMME ensemble monthly projections of sea-surface temperature (SST) and precipitation from 30 years of hindcasts with observations of precipitation and temperature for target regions. Since raw model forecasts are well-known to have structural biases, a cross-validated multivariate regression methodology (CCA) is used to link the model projected states as predictors to the predictands of the target region. The target regions include a number of basins in East and South Africa as well as the Ganges / Baramaputra / Meghna basin complex. The MOS approach used address spatial downscaling. Temporal disaggregation of monthly seasonal forecasts is achieved through use of a tercile bootstrapping approach. We interpret the results of these studies, the levels of skill by several metrics, and key uncertainties

Predicting the Effects of Cerulean Warbler, Dendroica cerulea Management on Eastern Ontario Bird Species

Single-species habitat management strategies are often undertaken without explicit consideration of their effects on the larger community. Here we explore the potential effects of managing eastern Ontario deciduous forests for the Cerulean Warbler (Dendroica cerulea) by examining its potential as a biodiversity indicator species and as an umbrella species. Our results indicate that the Cerulean Warbler would not be an effective biodiversity indicator, as its distribution across the studied landscape did not coincide with areas of high avian species richness. However, the Cerulean Warbler may be effective as an umbrella species for the maintenance of populations of other canopy-nesting species that require mature deciduous forest habitats. It is hoped that the conclusions reached in Ontario, while perhaps not directly transferable to all parts of the breeding range, encourage other Cerulean Warbler researchers to ask similar questions in their study areas

Intraseasonal Variations in Tropical Energy Balance: Relevance to Climate Sensitivity?

Intraseasonal variability of deep convection represents a fundamental mode of organization for tropical convection. While most studies of intraseasonal oscillations (ISOs) have focused on the spatial propagation and dynamics of convectively coupled circulations, here we examine the projection of ISOs on the tropically-averaged heat and moisture budget. One unresolved question concerns the degree to which observable variations in the "fast" processes (e.g. convection, radiative / turbulent fluxes) can inform our understanding of feedback mechanisms operable in the context of climate change. Our analysis use daily data from satellite observations, the Modern Era analysis for Research and Applications (MERRA), and other model integrations to address these questions: (i) How are tropospheric temperature variations related to that tropical deep convection and the associated ice cloud fractional amount (ICF), ice water path (IWP), and properties of warmer liquid clouds? (ii) What role does moisture transport play vis-a-vis ocean latent heat flux in enabling the evolution of deep convection to mediate PBL - free atmospheric temperature equilibration? (iii) What affect do convectively generated upper-tropospheric clouds have on the TOA radiation budget? Our methodology is similar to that of Spencer et al., (2007 GRL ) whereby a composite time series of various quantities over 60+ ISO events is built using tropical mean tropospheric temperature signal as a reference to which the variables are related at various lag times (from -30 to +30 days). The area of interest encompasses the global oceans between 20oN/S. The increase of convective precipitation cannot be sustained by evaporation within the domain, implying strong moisture transports into the tropical ocean area. The decrease in net TOA radiation that develops after the peak in deep convective rainfall, is part of the response that constitutes a "discharge" / "recharge" mechanism that facilitates tropical heat balance maintenance on these time scales. However, water vapor and hydrologic scaling relationships for this mode of variability cast doubt on the utility of ISO variations as proxies for climate sensitivity response to external radiatively forced (e.g. greenhouse gas-induced) climate change
