The impact of a high versus a low glycaemic index breakfast cereal meal on verbal episodic memory in healthy adolescents

In this study, healthy adolescents consumed a) a low glycaemic index (G.I.) breakfast cereal meal, or b) a high G.I. breakfast cereal meal, before completing a test of verbal episodic memory in which the memory materials were encoded under conditions of divided attention. Analysis of remembering/forgetting indices revealed that the High G.I. breakfast group remembered significantly more items relative to the Low G.I. breakfast group after a long delay. The superior performance observed in the High G.I. group, relative to the Low G.I. group, may be due to the additional glucose availability provided by the high G.I. meal at the time of memory encoding. This increased glucose availability may be necessary for effective encoding under dual task conditions

Voices From the Street: A Survey of Homeless Youth by Their Peers

Georgia Welfare Leavers Study - Initial Results

Funded by the Department of Human Resources, the Georgia State welfare leavers study is tracking families as they leave Temporary Assistance to Needy Families (TANF). Using administrative data combined with the results of a telephone interview, the project monitors the impact of leaving welfare on the individuals, their families and their communities.2 The study includes both single-parent and child-only leavers and, unlike studies in some other states, does include individuals who have returned to the rolls. The response rate for this study approaches 35% and continues to rise as the project makes intensive efforts to locate respondents. Preliminary analyses of administrative data indicate that interview respondents closely resemble individuals whom the project has been unable to interview

The use of high altitude remote sensing in determining existing vegetation and monitoring ecological stress

High altitude color and multispectral black and white photography was used to survey existing vegetation and soil conditions on the Empire Ranch where large scale development will soon begin. Utilizing stereo pairs of the high altitude color photography, four vegetation classifications were discernable as a function of topography and foliage characteristics. In contrast to the undeveloped Ranch, the same photography was used to detect environmental changes in the Tucson metropolitan area as a result of rapid urbanization. The most prevalent change related to development is the removal of vegetation in high density areas to allow for housing starts. Erosion then occurs where vegetation has been removed

How Parents Use Time and Money

[Excerpt] This article examines weekday resource allocation decisions of married couples with a husband employed full time and with children under 18. These decisions relate, among other things, to working for pay; doing unpaid household work; purchasing services such as childcare, laundry and drycleaning, and food away from home; and eating out. Information about spending decisions was obtained from the 2009 Consumer Expenditure Survey (CE) and information about time use was obtained from the 2009 American Time Use Survey (ATUS). Results show that, Regardless of employment status, wives were more likely than husbands to spend time in household activities. On an average weekday, married fathers spent more time working than married mothers did, even married mothers employed full time. The proportion of families reporting childcare expenses and the average amount spent by those reporting were highest for families with full-time working wives and lowest for families with wives not employed for pay. Consistent with other research, working-wife families did not spend more on housekeeping and laundry services than did families with wives not employed for pay. Families with full-time working wives spent the greatest dollar amount on food away from home, but there was no significant difference in spending between families with part-time working wives and families with wives not employed for pay

Formal certification and compliance for run-time service environments

With the increased awareness of security and safety of services in on-demand distributed service provisioning (such as the recent adoption of Cloud infrastructures), certification and compliance checking of services is becoming a key element for service engineering. Existing certification techniques tend to support mainly design-time checking of service properties and tend not to support the run-time monitoring and progressive certification in the service execution environment. In this paper we discuss an approach which provides both design-time and runtime behavioural compliance checking for a services architecture, through enabling a progressive event-driven model-checking technique. Providing an integrated approach to certification and compliance is a challenge however using analysis and monitoring techniques we present such an approach for on-going compliance checking

Occurrence and Behavior of Juvenile Red Snapper, Lutjanus campechanus, on Commercial Shrimp Fishing Grounds in the Northeastern Gulf of Mexico

Red snapper, Lutjanus campechanus, is subject to significant overfishing in U.S. Gulf of Mexico waters, and regulations are being implemented to reduce fishing mortality and restore them to a 20% spawning potential ratio by the year 2009. One source of mortality that must be reduced to achieve this goal is the incidental capture ofjuvenile red snappers in shrimp, Penaeus spp., trawls. NOAA's National Marine Fisheries Service is conducting research to develop shrimp trawl modifications to reduce the snapper bycatch. An important part of this research is the study of juvenile red snapper behavior on commercial shrimp grounds and in relation to trawling gear. An area of high juvenile red snapper abundance was identified off the coast of Mississippi. Most snappers were observed around structures or objects on the bottom which they appeared to use for refuge or orientation. Those ranging over barren bottom had no apparent point of orientation. When encountered by shrimp trawls, most juvenile snappers rose above the trawl footrope and fell back into the trawl. These observations have directed research toward modifying shrimp trawls to release juvenile red snappers after entry, rather than preventing them from entering a shrimp trawl

The Light Growth Response of Phycomyces

With the help of an automated tracking system we have studied the characteristics of the transient light growth response of Phycomyces. The response shows a sharply defined latency. The Q10 of the reciprocal latency is 2.4. Response patterns at different peaks of the action spectrum are the same. The gradual variation of response magnitude over a wide range of adapted intensifies parallels that of phototropism. The responses to saturating stimuli exhibit a strong oscillation with a constant period of 1.6 min and variable damping. The growth responses to sinusoidally varying light intensities show a system bandwidth of 2.5 x 10-3 Hz. The linear dependence of phase shift on frequency is largely attributable to the latency observed with pulse stimuli. In the high intensity range a previously suspected increase of the steady-state growth rate with intensity has been confirmed. The light growth responses of mutants selected for diminished phototropism have been investigated. Many of these mutants have sizable but grossly distorted growth responses

Georgia Welfare Leavers Study - Technical Appendices

The following provides an overview of the Georgia State study and compares it to that of leavers studies in other states. While there are similarities, this study differs in several crucial ways from these other studies
