Space-borne remotely sensed data can provide valuable insight into cryospheric processes in remote high-latitude regions for which direct observations are limited. In this study we use synthetic aperture radar (SAR) and Landsat imagery to evaluate recent changes in the ice cover of Upper and Lower Murray Lakes (81u209N, 69u309W) on Ellesmere Island, Nunavut, Canada. These data highlight changes...

Laser-induced fluorescence emission (L.I.F.E.) images were obtained in situ following 532 nm excitation of cryoconite assemblages in the ice covers of annual and perennially frozen Antarctic lakes during the 2008 Tawani International Expedition to Schirmacher Oasis and Lake Untersee in Dronning Maud Land, Antarctica. Laser targeting of a single millimeter-scale cryoconite results in multiple ne...

OBJECTIVE This study is a descriptive investigation of trends in BMI in the USA over time, across race/ethnicity, gender, and socioeconomic status (SES) groups, and across different datasets. METHODS The study analyzes micro-level data from three widely used cross-sectional US health datasets: the National Health and Nutrition Examination Survey (NHANES), the National Health Interview Survey ...

Recent proxy measurements reveal that subglacial lakes beneath modern ice sheets periodically store and release large volumes of water, providing an important but poorly understood influence on contemporary ice dynamics and mass balance. This is because direct observations of how lake drainage initiates and proceeds are lacking. Here we present physical evidence of the mechanism and geometry of...

This study empirically investigates whether agglomeration discourages married couples' fertility decisions. Exploiting Japanese social survey data to control for economic and social factors underlying fertility, it examines whether agglomeration affects completed fertility and the timing of childbirth. Results indicate that agglomeration impedes completed fertility. In addition, this study find...

Organization Democrats far and near acted as if they were ashamed of their own President. His name was barely mentioned in speeches and campaign literature. With an eye to the Gallup polls, which indicated a drop in Mr. Truman’s popularity from a honeymoon percentage of 87 percent to an October brown of 32 percent, they decided then he was to be written off as a loss. Republicans made the most ...

This study aims to estimate the recreational use values of Great Lakes beaches using a two-level nested logit Random Utility Model. The choice set contains all 594 public Great Lakes beaches in Michigan. Beach sites located in the same Great Lakes water body are arranged into a nest. The trip data were obtained from a 2006 online survey using a web-panel of Michigan adults accessed through Surv...

Air temperature and winter precipitation changes over the last five decades have impacted the timing, duration, and thickness of the ice cover on Arctic lakes as shown by recent studies. In the case of shallow tundra lakes, many of which are less than 3 m deep, warmer climate conditions could result in thinner ice covers and consequently, in a smaller fraction of lakes freezing to their bed in ...

In this paper, the trend and determinants of health and poverty among the elderly in rural India is analysed. Two rounds of National Sample Survey (NSS) data for the year 1995-96 and 2004 are employed. The analysis has been done with independent and pooled datasets. Our analysis shows that levels of consumption poverty have declined marginally between 1995-96 and 2004 while increased proportion...
