Wheat Productivity Estimates Using LANDSAT Data

The author has identified the following significant results. The biological leaf area index data show that there can be large variations in field vegetative condition from point to point. This is especially true in flood-irrigated fields, in which plant density (and development) varies drastically between rows that are in channels vs. those that are in raised areas. Considerable care must be used in interpreting the significance of isolated leaf area index measurements made from a single wheat row

Protein sectors: statistical coupling analysis versus conservation

Statistical coupling analysis (SCA) is a method for analyzing multiple sequence alignments that was used to identify groups of coevolving residues termed "sectors". The method applies spectral analysis to a matrix obtained by combining correlation information with sequence conservation. It has been asserted that the protein sectors identified by SCA are functionally significant, with different sectors controlling different biochemical properties of the protein. Here we reconsider the available experimental data and note that it involves almost exclusively proteins with a single sector. We show that in this case sequence conservation is the dominating factor in SCA, and can alone be used to make statistically equivalent functional predictions. Therefore, we suggest shifting the experimental focus to proteins for which SCA identifies several sectors. Correlations in protein alignments, which have been shown to be informative in a number of independent studies, would then be less dominated by sequence conservation.Comment: 36 pages, 17 figure

A Meaner, More Callous Digital World for Youth? The Relationship Between Violent Digital Games, Motivation, Bullying and Civic Behavior amongst Children

The relationship between violent digital games and youth behavior remains contested in the scholarly literature. To date considerable scholarship has focused on university students with fewer studies of adolescents or children. The current study examines correlational relationships between violent game exposure and bullying behaviors, antisocial attitudes, civic attitudes and civic behaviors in a sample of 304 children from the United Kingdom (Mean age = 12.81). The paper also considered motivational influences on use of violent digital games. Results indicated that violent game exposure did not correlate meaningfully with either antisocial or civic behaviors or attitudes. These results are discussed in a motivational and developmental context

Modeling of transient heat pipe operation

The overall goal is to gain a better understanding of the transient behavior of heat pipes operating under both normal and adverse conditions. Normal operation refers to cases where the capillary structure remains fully wetted. Adverse operation occurs when drying, re-wetting, choking, noncontinuum flow, freezing, thawing etc., occur within the heat pipe. The work was redirected towards developing the capability to predict operational behavior of liquid metal heat pipes used for cooling aerodynamic structures. Of particular interest is the startup of such heat pipes from an initially frozen state such as might occur during re-entry of a space vehicle into the Earth's atmosphere or during flight of hypersonic aircraft

Modeling of Transient Heat Pipe Operation

The major goal of this project is to develop mathematical models of heat pipes which can be used to predict transient behavior under normal and adverse conditions. The models and solution techniques are to be formulated so that they can be incorporated into existing NASA structural design codes. The major parameters of interest are heat flux distribution, temperature distribution, working fluid pressure distribution, fluid and containment thermal and mechanical properties and geometry. Normal transient operation is taken to be operating conditions where the capillary structure remains fully wetted. Adverse transient operation occurs when drying, re-wetting, choking, non-continuum flow, thawing, freezing, etc., occur in the internal heat pipe working fluid

Sexualized Video Games, Sexist Attitudes and Empathy Toward Victims of Rape: Correlational Evidence for a Relationship Is Minimal in an Online Study

Background: Continued debate exists regarding whether sexualization in games can influence sexist attitudes and reduced empathy toward women in real life. At present, evidence has been mixed with little clear consensus among scholars. Intervention: The present study examined the relationship between sexualized content in video games and players’ sexist attitudes and empathy. This study tests whether such relationships exist once other factors including gender and trait aggression are controlled. Methods: A correlational design was used with an online sample of 125 participants. Heirarchical multiple regression was employed as well as PROCESS to test for interactions between sexualized game content and trait aggression. Results: Contrary to popular concerns, exposure to sexualized content in video games was associated with neither decreased empathy nor higher sexist attitudes. Sexualized content in games was associated with slightly lower sexist beliefs and increased empathy for those high in trait aggression. No effects were observed for those low in trait aggression. Discussion: The current study provides evidence against beliefs sexist attitudes are cultivated by video games. If anything, exposure to sexist games may be associated with greater empathy and reduced sexism among more aggressive individuals
