If an observer sees a flashed (briefly presented) object that is aligned with a moving target, the perceived position of the flashed object usually lags the perceived position of the moving target. This has been referred to as the flash-lag effect, and the flash-lag effect has been suggested to reflect how an observer compensates for delays in perception that are due to neural processing times and is thus able to interact with dynamic stimuli in real time. Characteristics of the stimulus and of the observer that influence the flash-lag effect are reviewed, and the sensitivity or robustness of the flash-lag effect to numerous variables is discussed. Properties of the flash-lag effect and how the flash-lag effect might be related to several other perceptual and cognitive processes and phenomena are considered. Unresolved empirical issues are noted. Theories of the flash-lag effect are reviewed, and evidence inconsistent with each theory is noted. The flash-lag effect appears to involve low-level perceptual processes and high-level cognitive processes, reflects the operation of multiple mechanisms, occurs in numerous stimulus dimensions, and occurs within and across multiple modalities. It is suggested that the flash-lag effect derives from more basic mislocalizations of the moving target or flashed object and that understanding and analysis of the flash-lag effect should focus on these more basic mislocalizations rather than on the relationship between the moving target and the flashed object. © 2014 American Psychological Association.

Organophosphorus compounds are important in everyday applications ranging from agriculture to medicine and are used in flame retardants and other materials. Although organophosphorus chemistry is known as a mature and specialized area, researchers would like to develop new methods for synthesizing organophosphorus compounds to improve the safety and sustainability of these chemical processes.The vast majority of compounds that contain a phosphorus-carbon bond are manufactured using phosphorus trichloride (PCl 3) as an intermediate. However, these reactions require chlorine, and researchers would like to avoid the use of PCl3 and develop safer chemistry that also decreases energy consumption and minimizes waste. Researchers have already proposed and discussed two primary strategies based on elemental phosphorus (P4 or Pred) or on phosphine (PH 3) as alternatives to PCl3. However, phosphinates, an important class of phosphorus compounds defined as any compound with a phosphorus atom attached to two oxygens, R1R2P(O)(OR) (R1/R2 = hydrogen/carbon), offer another option.This Account discusses the previously neglected potential of these phosphinates as replacements of PCl3 for the preparation of organophosphorus compounds. Because of their strong reductive properties, industry currently uses the simplest members of this class of compounds, hypophosphites, for one major application: electroless plating. In comparison with other proposed PCl 3 surrogates, hypophosphorous derivatives can offer improved stability, lower toxicity, higher solubility, and increased atom economy. When their reducing power is harnessed to form phosphorus-carbon or phosphorus-oxygen bonds, these compounds are also rich and versatile precursors to organophosphorus compounds. This Account examines the use of transition metal-catalyzed reactions such as cross-coupling and hydrophosphinylation for phosphorus-carbon bond formation. Because the most important industrial organophosphorus compounds include compounds triply or quadruply bound to oxygen, I also discuss controlled transfer hydrogenation for phosphorus-oxygen bond formation. I hope that this Account will further promote research in this novel and exciting yet much underdeveloped area of phosphinate activation. © 2013 American Chemical Society.

Dissolution of lignocellulose in ionic liquids is a promising route to synthesizing fuels and chemical feedstocks from woody plant materials. While cellulose dissolution is well-understood, less is known about the differences between ionic liquids' interactions with cellulose vs. lignin. This work uses dispersion-corrected density functional theory (DFT-D) to model the interactions of imidazolium chloride ionic liquid anions and cations with (1,4)-dimethoxy-β-d-glucopyranose and 1-(4-methoxyphenyl)-2-methoxyethanol as models for cellulose and the lignin polyphenol, respectively. The cellulose model preferentially interacts with Cl-, confirming previous experimental and theoretical studies. However, the lignin model has significant π-stacking and hydrogen bonding interactions with imidazolium cation. These results are robust to changes in the computational details, and suggest that the ionic liquid cations play important roles in tuning the relative solubilities of lignin and cellulose. Calculations predict that the extended π-systems of benzimidazolium ionic liquids yield stronger interactions with lignin, showing potential for improved lignocellulose solvents. © the Owner Societies.

A project manager makes decisions based on what he or she sees and understands. In large, complex projects (or programs), a manager cannot see the entire "territory" between project start and completion and therefore must rely on models or "maps" to support planning and decisions. When it comes to planning and coordinating work, project managers commonly use a variety of process model views such as flowcharts, Gantt charts, responsibility assignment matrices, and narrative descriptions. However, these views may not contain the right information to best support the purpose or decision at hand. This paper investigates the fit between model views (a kind of technology) and the managerial decisions (a kind of task) they support. Through analysis of the literature and case study data, this research identifies: (1) a set of 28 purposes for which managers draw upon process models for decision support, (2) a set of 15 views of process models, and (3) a set of 56 information attributes involved in supporting the purposes and provided by the views. The paper develops new measures of the sufficiency and extraneousness of the attributes for each purpose and view. Analysis of the evidence suggests substantial misalignment between managers' purposes and tools. Drawing on task-technology fit theory, the paper discusses the theoretical and managerial implications of these results and contributes a new construct, purpose-view alignment, which may help explain project success in future studies. The paper also presents insights for researchers and managers on how to develop customized views that are more suitable for particular managerial tasks. © 2009 Elsevier B.V.

Does vulnerability to disease influence the decisions that people make? Much is known about the effects of illness on worker absenteeism and disability, but little is known about the effects of disease vulnerability on decision making, which can play a key role in quality of life and the nations economic growth. This research examines the link between disease vulnerability due to immunological functioning or the environmental context and decision making with a series of studies. This research is based in a novel integration of theory and methods from several fields including psychoneuroimmunology, experimental social psychology, and evolutionary biology. It is easy to imagine that given a disease vulnerability one would engage in self-protective decisions and behaviors. However, by combining these theories the scientists arrive at an innovative and counterintuitive prediction. That is, instead of moving us toward safe decisions, vulnerability to disease that stems from environmental and immunological sources may actually lead to risky decisions. The findings of this research could be used to promote the physical health of our citizens, benefiting their well-being and our nations economy.

The proposed research will test the hypothesis that greater vulnerability to pathogens and disease increase risky decision making. The research tests decision making in the context of biologically derived, immune-based vulnerabilities or perceived changes in the external pathogen load. To test the link between vulnerability and risky decisions, Dr. Sarah Hill, from Texas Christian University, and her colleagues, propose a multi-disciplinary correlational study that measures the relationship between multiple facets of peripheral blood-based immune function and decision-making. This first-of-its kind study will provide important new insights into whether key measures of immunological function predict risk-taking and its attitudinal and cognitive antecedents. Next, the researchers propose seven laboratory experiments in which they use an established priming procedure to experimentally induce perceived vulnerability to disease, and measure subsequent psychological and behavioral changes known to promote risky decision-making. The proposed research promises to offer important new theoretical advances to numerous fields including social, health, evolutionary, clinical, and personality psychology, decision making science, and psychoneuroimmunology. This research will yield important new insights into factors that promote a variety of risky decisions that lead to risk-taking behaviors among those people who are most vulnerable to the ill effects of these behaviors.

NON-TECHNICAL SUMMARY

This award supports theoretical and computational research and education on a suite of theoretical tools that will quantify electron delocalization on metal surfaces. Chemical reactions on metal and metal oxide surfaces are central to phenomena from heterogeneous catalysis to corrosion to the properties of metal nanostructures. Quantum mechanics postulates that the electrons in a molecule, solid, or surface are not spatially restricted to one point, but delocalize in a region of space. For example, the covalent bonds that hold molecules together involve electrons delocalizing between atoms. Chemical reactions converting iron into rust, or simple molecules into pharmaceuticals, must break bonds and temporarily re-localize electrons to atoms. Better understanding of delocalization in surface chemistry could have an enormous impact on developing industrial catalysts, nanomaterials, and many other systems.

Unfortunately, our understanding of delocalization on surfaces faces two major limitations. First, delocalization is a fundamentally non-classical and non-intuitive phenomenon. Second, the equations modeling the interaction of electrons with each other generally cannot be solved exactly. The standard approximations used in computer simulations of electrons on metal surfaces are particularly inaccurate for the delocalized and stretched bonds which are important in catalysis. More accurate approximations often require enormously demanding computational resources. Accordingly, better models would be a tremendous benefit. The PI has developed new tools that quantify electronic delocalization in space. This award supports application of these tools to the fundamental and practical problems associated with electron delocalization on metal surfaces.

This project integrates teaching and undergraduate research, providing specific research projects for undergraduate researchers and specific mentoring roles for graduate students. The PI will also develop an online component for his new course Computational Chemistry for Experimentalists, aimed at providing non-specialist users at his institution and around the world with a practical introduction to electronic structure theory.

TECHNICAL SUMMARY

This award supports theoretical and computational research and education on a suite of theoretical tools that will quantify electron delocalization on metal surfaces. Chemical reactions on metal and metal oxide surfaces are central to phenomena from heterogeneous catalysis to corrosion to the properties of metal nanostructures. Computational models of reactions at surfaces must capture both the non-classical delocalization of electrons in chemical bonds, and the correlation-induced re-localization that occurs during bond breaking. The standard density functional theory approximations in surface science have major limitations for modeling these effects. This leads to significant errors in predicted reaction rates.

The PIs group has developed and implemented a suite of tools, based on the one-particle density matrix, which quantify delocalization in calculated wavefunctions. The team will use these tools to quantify how the presence of a catalyst surface affects the delicate interplay between delocalization and correlation-induced re-localization central to bond breaking and reaction rates. They will also use the tools in real-space models of non-dynamical correlation for computationally tractable treatments of chemistry at metal surfaces. The fundamental ingredient in such models is the extent to which an electron at a given point delocalizes past the expected length scale of a standard (generalized gradient approximation) density functional.

This project integrates teaching and undergraduate research, providing specific research projects for undergraduate researchers and specific mentoring roles for graduate students. The PI will also develop an online component for his new course Computational Chemistry for Experimentalists, aimed at providing non-specialist users at his institution and around the world with a practical introduction to electronic structure theory.
