Development and application of color television for Apollo 15 and beyond

The development of the television system used for Apollo 15 mission is discussed. Data cover identification of factors contributing to the high quality of pictures generated on the lunar surface and exploration of several possible present and future uses of the television equipment developed

Excimer laser processing of backside-illuminated CCDS

An excimer laser is used to activate previously implanted dopants on the backside of a backside-illuminated CCD. The controlled ion implantation of the backside and subsequent thin layer heating and recrystallization by the short wavelength pulsed excimer laser simultaneously activates the dopant and anneals out implant damage. This improves the dark current response, repairs defective pixels and improves spectral response. This process heats a very thin layer of the material to high temperatures on a nanosecond time scale while the bulk of the delicate CCD substrate remains at low temperature. Excimer laser processing backside-illuminated CCD's enables salvage and utilization of otherwise nonfunctional components by bringing their dark current response to within an acceptable range. This process is particularly useful for solid state imaging detectors used in commercial, scientific and government applications requiring a wide spectral response and low light level detection

Recalibrating valence weighting biases to promote changes in rejection sensitivity and risk-taking

Past research has found that modifying individuals' valence weighting tendencies by recalibrating them to weight positive and negative valence in a more balanced manner influenced a variety of judgments. The current research examines the utility of the recalibration procedure as a targeted intervention. In Experiment 1, we recruited participants high in rejection sensitivity (who are known to exhibit a negative weighting bias) and in Experiment 2, we recruited participants with high risk tendencies (who are known to exhibit a positive weighting bias). In both experiments, participants first played BeanFest, in which they were presented with beans varying in shape and speckles and learned which increased or decreased points. They later classified the game beans, as well as novel ones varying in their resemblance to the known positives or known negatives, as good or bad. In the recalibration condition, participants were told if they classified each bean correctly, thus receiving feedback regarding the appropriate weighting of resemblance to a known positive versus a negative. The controls, who received no feedback, were less accurate at classifying the novel the beans than the recalibration participants. Furthermore, in Experiment 1, the recalibration condition subsequently exhibited lower sensitivity to rejection than the control condition, with this reduction being stronger for individuals initially higher in rejection sensitivity. This effect was still present a week later. In Experiment 2, the recalibration condition reported diminished risk-tendencies, again with this effect being stronger for individuals with initially higher riskiness, and persisting for a week. Even more importantly, recalibration participants also engaged in less risky behavior on a laboratory task

Moral anger, but not moral disgust, responds to intentionality

We propose that, when people judge moral situations, anger responds to the contextual cues of harm and intentionality. On the other hand, disgust responds uniquely to whether or not a bodily norm violation has occurred; its apparent response to harm and intent is entirely explained by the co-activation of anger. We manipulated intent, harm, and bodily norm violation (eating human flesh) within a vignette describing a scientific experiment. Participants then rated their anger, disgust, and moral judgment, as well as various appraisals. Anger responded independently of disgust to harm and intentionality, while disgust responded independently of anger only to whether or not the act violated the bodily norm of cannibalism. Theoretically relevant appraisals accounted for the effects of harm and intent on anger; however, appraisals of abnormality did not fully account for the effects of the manipulations on disgust. Our results show that anger and disgust are separately elicited by different cues in a moral situation

Assessment of potential mare stocking impacts on resource access rights and livelihoods in Komio village, Niger River Delta, Mali

The Community-based Fish Culture in Seasonal Floodplains and Irrigation Systems (CBFC) project is a five year research project supported by the Challenge Program on Water and Food (CPWF), with the aim of increasing productivity of seasonally occurring water bodies through aquaculture. The project has been implemented in Bangladesh, Cambodia, China, Mali and Vietnam, where technical and institutional options for community based aquaculture have been tested. The project began in 2005 and was completed in March 2010. In the context of the CP-35 project, this visit follows up on a preliminary assessment of livelihoods and institutions in Komio village, Mali conducted by consultants Joffre and Lajaunie. The objective of the visit was to determine how stocking mares around Komio village may impact livelihoods and access rights to aquatic resources. Additional insights were gained from the governance experiences and livelihood impacts of village irrigation schemes (PIVs).Fishing rights, River fisheries, Livelihoods
