Chemical accuracy in ab initio thermochemistry and spectroscopy: current strategies and future challenges

Abstract: The current state of the art in wavefunction-based electronic structure methods is illustrated via discussions of the most important effects incorporated into a selection of high-accuracy methods chosen from the chemical literature. If one starts with a high-quality correlation treatment, such as provided by the CCSD(T) coupled cluster method, the leading effects include convergence of the results with respect to the 1-particle basis set, (outer)core/valence correlation, scalar relativistic effects and a number of smaller effects. For thermochemical properties such as the heat of formation, the zero-point vibrational energy also becomes important, introducing its own set of difficulties to the computational approach. Changes in the various components as the chemical systems incorporate heavier elements and as the size of the systems grows are also considered. Finally, challenges arising from the desire to extend existing methods to transition metal and heavier elements are considered.

A comprehensive model of customer direct and indirect revenge: understanding the effects of perceived greed and customer power

Abstract: This article develops and tests a comprehensive model of customer revenge that contributes to the literature in three manners. First, we identify the key role played by the customer’s perception of a firm’s greed—that is, an inferred negative motive about a firm’s opportunistic intent—that dangerously energizes customer revenge. Perceived greed is found as the most influential cognition that leads to a customer desire for revenge, even after accounting for well studied cognitions (i.e., fairness and blame) in the service literature. Second, we make a critical distinction between direct and indirect acts of revenge because these sets of behaviors have different repercussions—in “face-to-face” vs. “behind a firm’s back”—that call for different interventions. Third, our extended model specifies the role of customer perceived power in predicting these types of behaviors. We find that power is instrumental—both as main and moderation effects—only in the case of direct acts of revenge (i.e., aggression and vindictive complaining). Power does not influence indirect revenge, however. Our model is tested with two field studies: (1) a study examining online public complaining, and (2) a multi-stage study performed after a service failure.

Principles for Constructing Web Surveys

Abstract: Summary and Conclusions Use of the World Wide Web to conduct surveys provides enormous opportunities as well aschallenges. The cost advantages of collecting large amounts of data at very little cost means thatits use will escalate rapidly. At the same time, maintaining quality, whereby the results ofsurveys can be generalized to a large population is far from automatic.Respondent-friendly questionnaire design, found important to improving response to self-administered mail questionnaires, is also important for the development of web questionnaires.However, in a web context the term takes on a broader meaning. A respondent-friendly webquestionnaire is one that interfaces effectively with the wide variety of computers and browserspossessed by respondents. It also makes other aspects of the response task easy and interestingfor the respondent to complete. Respondent-friendly designed is aimed explicitly at reducingthree of the four types of error that typically prevent accurate surveys from being done, i.e.,nonresponse, measurement, and coverage of the survey population.Three important criteria for achieving respondent-friendly design have been stated. Theyinclude, first, compliancy with technology available to the respondent. If a browser cannotrecognize the programmed information being sent to it, the respondent cannot receive it.Questionnaires that use advanced programming that takes longer transmission times and requiresmore advanced browsers may result in unintended coverage and nonresponse error. A secondcriterion is the necessity of bridging between the logic by which respondents expect a question-naire to operate and the logic associated with operating a computer. It’s this connection thatprovides a questionnaire design challenge not previously faced by survey methodologists. Inaddition to these criteria, web designers must also consider the high likelihood that coverageproblems will require that most quality web surveys, for the foreseeable future, will require themixing of survey modes, whereby some respondents are surveyed by mail or telephone whileothers are surveyed via the web.

Biofluidmechanics of Reproduction

Abstract: Mammalian fertilization requires the coordinated activity of motile spermatozoa, muscular contractions of the uterus and oviduct, as well as ciliary beating. These elastic structures generate forces that drive fluid motion, but their configurations are, in turn, determined by the fluid dynamics. We review the basic fluid mechanical aspects of reproduction, including flagellar/ciliary beating and peristalsis. We report on recent biological studies that have shed light on the relative importance of the mechanical ingredients of reproduction. In particular, we examine sperm motility in the reproductive tract, ovum pickup and transport in the oviduct, as well as sperm-egg interactions. We review recent advances in understanding the internal mechanics of cilia and flagella, flagellar surface interaction, sperm motility in complex fluids, and the role of fluid dynamics in embryo transfer. We outline promising computational fluid dynamics frameworks that may be used to investigate these complex, fluid-structure interactions.

A longitudinal study of relational aggression, physical aggression, and children's social-psychological adjustment.

Abstract: Although great strides have recently been made in our understanding of relational aggression and its consequences, one significant limitation has been the lack of prospective studies. The present research addressed this issue by identifying and assessing groups of relationally aggressive, physically aggressive, relationally plus physically aggressive (co-morbid), and nonaggressive children during their third grade year in elementary school and then reassessing them a year later, during fourth-grade (N = 224, 113 girls). Two aspects of social-psychological adjustment were assessed during both assessment periods including internalizing difficulties (i.e., withdrawal, depression/anxiety, and somatic complaints) and externalizing problems (i.e., aggressive behavior, delinquency). It was revealed that the strongest predictor of future social-psychological adjustment problems and increases in these problems from third to fourth was the combination of relational and physical aggression. Relational aggression also contributed unique information, relative to physical aggression, in the prediction of future maladjustment. Implications of these findings for future research and prevention efforts, particularly for aggressive girls, are discussed.
