Landsat Enhanced Thematic Mapper Plus (ETM+) images were compared to Terra-MODIS imagery for detecting forest changes in northern Maine’s industrial forest. Advantages of MODIS imagery compared to medium spatial resolution imagery, like Landsat TM or ETM+, are its temporal frequency, its low data volume to cover large forest regions and, the data are free to download over the Internet. The obje...

BACKGROUND The divorce rate has been increasing rapidly in Korea; the single rate and trends in divorce are also changing rapidly. This study aimed to examine the relationship between marital status and quality of life (QOL) in an attempt to understand these changes. We also investigated the relationship between QOL and marital status by age group. METHODS We used data from the Community Heal...

INTRODUCTION Sexual problems have been more prevalent among East Asian women than those from other areas of the world. However, Japanese women seldom tend to consult their treating physicians as such intimate problems are socially awkward topics to share and may be considered shameful. Presently, there is little data in the literature regarding women's sexual problems in Japan. AIMS We aimed ...

Record performances for Masters sporting events for swimming, cycling, triathlon, rowing, and weightlifting were analyzed and then compared with the authors' previously published results for Masters running, walking, and jumping sports events. Records were normalized using the 30s age records as a baseline, and studied through the various age ranges to the 90s. A curvilinear mathematical model ...

The interaction between ribosomal proteins of the 30s subunit with intact 50s subunits was investigated. Experiments with mixtures of total 30s proteins indicated that several 30s proteins including protein s4 would form a stable complex with 50s subunits. Further work with pure s4 indicates that this protein binds stoichiometrically to the 50s subunits, probably through protein-nucleic acid in...

Previous studies of symbiotic associations between scleractinians corals and Symbiodinium have demonstrated that the consortium of symbionts can change in response to environmental conditions. However, less is known about symbiont shuffling during early coral development, particularly in brooding species. This study examined whether Symbiodinium consortia (1) varied in Porites astreoides on sha...

Spatial and temporal vegetation contrasts between the nations of Haiti and the Dominican are analyzed using NDVI data derived from 30m resolution Landsat imagery and 8km resolution AVHRR imagery from the NOAA / NASA Pathfinder database. Analysis of vegetation dynamics in the Hispaniola border region indicates denser vegetation cover and a stronger correlation between elevation, slope, and NDVI ...

Using data from the National Longitudinal Study of Adolescent Health, this study examines the impact of high school cohort composition on the educational and labor market outcomes of individuals during their early 20s and again during their late 20s and early 30s. We find that the positive effects of having more high school classmates with a college educated mother on college attendance in the ...

Recently there has been increasing interest in the estimation of age-specific fecundability as a result of the progressive postponement of age at family formation in Western countries. It must be noted, however, that the possible negative effects of the postponement could act not only on the physiological component of the ability to conceive but also on the behavioural component (i.e., sexual a...

The cultural identity and tribal connectedness of American Indians are commonly believed to have been negatively affected by the urbanization process in which American Indians have been involved during the past half century. This phenomenological study examined the processes through which cultural identity was formed and maintained by a group of American Indians who had lived since childhood in...
