Preliminary Sizing and Performance Evaluation of Supersonic Cruise Aircraft

The basic processes of a method that performs sizing operations on a baseline aircraft and determines their subsequent effects on aerodynamics, propulsion, weights, and mission performance are described. The input requirements of the associated computer program are defined and its output listings explained. Results obtained by applying the method to an advanced supersonic technology concept are discussed. These results include the effects of wing loading, thrust-to-weight ratio, and technology improvements on range performance, and possible gains in both range and payload capability that become available through growth versions of the baseline aircraft. The results from an in depth contractual study that confirm the range gain predicted for a particular wing loading, thrust-to-weight ratio combination are also included

Toward a metaphor-enriched personality psychology.

Conventional wisdom on metaphor suggests that it is the province of poets, metaphor is an optional way of thinking, or that metaphor merely serves communication purposes. In this chapter, we show that such wisdom is at variance with how human beings actually think and function. We first provide a brief overview of the metaphor representation perspective. We then make a case for the utility of this perspective in understanding how people differ from each other and do so within a broader context of how personality has traditionally been assessed. We then present four lines of personality research inspired by the metaphor representation perspective. We conclude with a discussion of the challenges and unanswered questions involved in translating the metaphor representation perspective to personality psychology

Do you use your head or follow your heart? Self-location predicts personality, emotion, decision making, and performance.

The head is thought to be rational and cold, whereas the heart is thought to be emotional and warm. In 8 studies (total N = 725), we pursued the idea that such body metaphors are widely consequential. Study 1 introduced a novel individual difference variable, one asking people to locate the self in the head or the heart. Irrespective of sex differences, head-locators characterized themselves as rational, logical, and interpersonally cold, whereas heart-locators characterized themselves as emotional, feminine, and interpersonally warm (Studies 1–3). Study 4 showed that head-locators were more accurate in answering general knowledge questions and had higher grade point averages, and Study 5 showed that heart-locators were more likely to favor emotional over rational considerations in moral decision making. Study 6 linked self-locations to reactivity phenomena in daily life—for example, heart-locators experienced greater negative emotion on high stressor days. In Study 7, we manipulated attention to the head versus the heart and found that head-pointing facilitated intellectual performance, whereas heart-pointing led to emotional decision making. Study 8 replicated Study 3’s findings with a nearly year-long delay between the self-location and outcome measures. The findings converge on the importance of head–heart metaphors for understanding individual differences in cognition, emotion, and performance

Interpersonal cognitive self-focus as a function of neuroticism: Basal tendencies and priming effects

Self-focus is one mechanism that may account for the social-evaluative anxiety of individuals high in neuroticism. The present two studies (total N = 183) sought to cognitively model interpersonal self-focus. The cognitive task was a simple one in which participants simply categorized dyadic interpersonal pronouns, with reaction times as the dependent measure. When others engage us, the pronoun “me” refers to the other and the pronoun “you” refers to the self. Study 1 found a neuroticism by pronoun interaction on categorization time consistent with implicit interpersonal self-focus at high (but not low) levels of neuroticism establishing a basal tendency. Study 2 examined boundary conditions. Individuals high in neuroticism exhibited implicit self-focus particularly to the extent that they had been primed to think of themselves as submissive rather than dominant in their interpersonal interactions. Implications for understanding neuroticism, self-focus, and relationship functioning are discussed

Motor control accuracy: A consequential probe of individual differences in emotion regulation.

Two studies (total N = 147) sought to model emotion-regulation processes in cognitive-motoric terms. Hostile or nonhostile thoughts were primed and, immediately following, individuals held a joystick as accurately as possible on a presented visual target. Study 1 revealed that the activation of hostile thoughts impaired motor control at low levels of agreeableness but facilitated motor control at high levels of agreeableness, consistent with emotion-regulation views of this trait. Study 2 did not assess the trait of agreeableness but rather sought to determine whether better motor control following activated hostile thoughts would predict lesser reactivity to stressors in an experience-sampling protocol. It did, and relevant results are reported for daily anger, negative affect, and positive affect. In addition, and consistent with the agreeableness findings of Study 1, better motor control that follows hostile thoughts predicted greater empathy on high-stress days. Motor control probes of the present type thus appear consequential in understanding emotion-regulation processes and successes in emotion regulation

Identification and analysis of evolutionary selection pressures acting at the molecular level in five forkhead subfamilies

<p>Abstract</p> <p>Background</p> <p>Members of the forkhead gene family act as transcription regulators in biological processes including development and metabolism. The evolution of forkhead genes has not been widely examined and selection pressures at the molecular level influencing subfamily evolution and differentiation have not been explored. Here, <it>in silico </it>methods were used to examine selection pressures acting on the coding sequence of five multi-species FOX protein subfamily clusters; FoxA, FoxD, FoxI, FoxO and FoxP.</p> <p>Results</p> <p>Application of site models, which estimate overall selection pressures on individual codons throughout the phylogeny, showed that the amino acid changes observed were either neutral or under negative selection. Branch-site models, which allow estimated selection pressures along specified lineages to vary as compared to the remaining phylogeny, identified positive selection along branches leading to the FoxA3 and Protostomia clades in the FoxA cluster and the branch leading to the FoxO3 clade in the FoxO cluster. Residues that may differentiate paralogs were identified in the FoxA and FoxO clusters and residues that differentiate orthologs were identified in the FoxA cluster. Neutral amino acid changes were identified in the forkhead domain of the FoxA, FoxD and FoxP clusters while positive selection was identified in the forkhead domain of the Protostomia lineage of the FoxA cluster. A series of residues under strong negative selection adjacent to the N- and C-termini of the forkhead domain were identified in all clusters analyzed suggesting a new method for refinement of domain boundaries. Extrapolation of domains among cluster members in conjunction with selection pressure information allowed prediction of residue function in the FoxA, FoxO and FoxP clusters and exclusion of known domain function in residues of the FoxA and FoxI clusters.</p> <p>Conclusion</p> <p>Consideration of selection pressures observed in conjunction with known functional information allowed prediction of residue function and refinement of domain boundaries. Identification of residues that differentiate orthologs and paralogs provided insight into the development and functional consequences of paralogs and forkhead subfamily composition differences among species. Overall we found that after gene duplication of forkhead family members, rapid differentiation and subsequent fixation of amino acid changes through negative selection has occurred.</p

Implicit Self-Importance in an Interpersonal Pronoun Categorization Task

Object relations theories emphasize the manner in which the salience/importance of implicit representations of self and other guide interpersonal functioning. Two studies and a pilot test (total N = 304) sought to model such representations. In dyadic contexts, the self is a “you” and the other is a “me”, as verified in a pilot test. Study 1 then used a simple categorization task and found evidence for implicit self-importance: The pronoun “you” was categorized more quickly and accurately when presented in a larger font size, whereas the pronoun “me” was categorized more quickly and accurately when presented in a smaller font size. Study 2 showed that this pattern possesses value in understanding individual differences in interpersonal functioning. As predicted, arrogant people scored higher in implicit self-importance in the paradigm. Findings are discussed from the perspective of dyadic interpersonal dynamics

Submissive, inhibited, avoidant, and escape motivated: The correlates and consequences of arm-crossing.

Some scholars of nonverbal behavior contend that arm-crossing indicates a defensive orientation to the social environment, but relevant evidence is sparse. Three studies (N = 242) sought to investigate whether there is truth to this idea. Consistent with it, Study 1 found that people reporting higher arm-crossing frequencies scored higher in interpersonal submissiveness and were more inhibited in their social decision-making. To investigate causal processes, Studies 2 and 3 manipulated arm-crossing using a hypothesis-disguising cover story. Study 2 found that arm-crossing activated thoughts of the self’s submissiveness and social vulnerability. Study 3 focused on activated strategies for handling potential interpersonal violence. Participants in an arm-crossing condition, relative to a control condition, indicated that they would be more inclined to escape and less likely to attack. The studies converge on the idea that arm-crossing can signify and cause a defensive social orientation
