by more than 25% and increase drought frequency significantly 59 . As wash out by rain is a major sink for BC, large decreases in rainfall can have a positive feedback on BC concentrations. The other scenario is the so-called nuclear winter scenario 87, 88, 89 , in which large-scale increase in BC from
Self-determination and persistence in a real-life setting: Toward a motivational model of high school dropout.
- Journal of Personality and Social Psychology,
, 1997
"... The purpose of this study was to propose and test a motivational model of high school dropout. The model posits that teachers, parents, and the school administration's behaviors toward students influence students' perceptions of competence and autonomy. The less autonomy supportive the so ..."

school dropout using a prospective design and structural equation modeling. Overall, we believe that the present study should allow us to better understand the psychological processes involved in dropping out of high school as well as provide a test of intrinsicextrinsic motivation theory and research
Efficient graph-based genetic programming representation with multiple outputs
- International Journal of Automation and Computing
"... Abstract: In this work, we explore and study the implication of having more than one output on a Genetic Programming (GP) graph-representation. This approach, called, Multiple Interactive Outputs in a Single Tree (MIOST) is based on two ideas: (a) Firstly, we defined an approach, called Interactivit ..."

Behavioral theories and the neurophysiology of reward,
- Annu. Rev. Psychol.
, 2006
"... ■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories that can ..."

Abagyan. Large-scale prediction of protein geometry and stability changes for arbitrary single point mutations
- Proteins
, 2004
"... ABSTRACT We have developed a method to both predict the geometry and the relative stability of point mutants that may be used for arbitrary mutations. The geometry optimization procedure was first tested on a new benchmark of 2141 ordered pairs of X-ray crystal structures of proteins that differ by ..."

The role of the airline transportation network in the prediction and predictability of global epidemics.
- Proc. Natl Acad. Sci. USA 103,
, 2006
"... The systematic study of large-scale networks has unveiled the ubiquitous presence of connectivity patterns characterized by large-scale heterogeneities and unbounded statistical fluctuations. These features affect dramatically the behavior of the diffusion processes occurring on networks, determini ..."

Using Mutation Analysis for Assessing and Comparing Testing Coverage Criteria
- IEEE TRANSACTIONS ON SOFTWARE ENGINEERING
, 2006
"... The empirical assessment of test techniques plays an important role in software testing research. One common practice is to seed faults in subject software, either manually or by using a program that generates all possible mutants based on a set of mutation operators. The latter allows the systemati ..."

regarding the relationships between fault detection, test suite size, and control/data flow coverage. Although such questions have been partially investigated in previous studies, we can use a large number of mutants, which helps decrease the impact of random variation in our analysis and allows us to use a
Results from a Large-Scale Study of Performance Optimization Techniques forSource Code Analyses Based on Graph Reachability Algorithms
"... Abstract Internally, many source code analysis tools make use ofgraphs. For example, one of the oldest and most widely used internal graphs is the control-flow graph developed for use within a compiler. Work on compilation has also led to thedevelopment of the call graph, the procedure dependence gr ..."

Which random processes describe the tree of life? A large-scale study of phylogenetic tree imbalance.
- Syst. Biol.
, 2006
"... The explosion of phylogenetic studies not only provides a clear snapshot of biodiversity, but also makes it possible to infer how the diversity has arisen (see for example, The analysis of stochastic models of phylogenetic tree shape, which began with Yule in 1924, was revived in the mid-1970s by ..."
