Personality structure across cultures: A multimethod evaluation.

Personality structure was assessed in 4 countries (Canada, Finland, Poland, and Germany) using both an established verbal personality inventory and a new nonverbal personality questionnaire. A 5-factor structure was found to be highly robust in that it was replicated across the 4 cultures and across the 2 personality assessment methods. The data are discussed in terms of (1) the failure to support a semantic similarity interpretation of personality item responses, (2) the factorial validity of the new nonverbal personality questionnaire, and (3) the viability of the popular 5-factor model of personality.

Evaluating replicability of factors in the Revised NEO Personality Inventory: Confirmatory factor analysis versus Procrustes rotation.

Despite the empirical robustness of the 5-factor model of personality, recent confirmatory factor analyses (CFAs) of NEO Personality Inventory (NEO-PI) data suggest they do not fit the hypothesized model. In a replication study of 229 adults, a series of CFAs showed that Revised NEO-PI scales are not simple-structured but do approximate the normative 5-factor structure. CFA goodness-of-fit indices, however, were not high. Comparability analyses showed that no more than 5 factors were replicable, which calls into question some assumptions underlying the use of CFA. An alternative method that uses targeted rotation was presented and illustrated with data from Chinese and Japanese versions of the Revised NEO-PI that clearly replicated the 5-factor structure.

Construct validity and the predictability of behavior.

Recurring assessment problems in personality research related to the cross-situational consistency and predictability of behavior are evaluated in light of modern construct-oriented measurement theory. A recent study of the domain of conscientiousness behaviors (Mischel & Peake, 1982) is used to illustrate the consequences of not applying well-established strategies for the development and validation of psychological measures. It is argued that a careful specification of the behavioral exemplars of a trait domain and their interrelations is an essential precondition for the construct validity of a measure and for evidence of behavioral consistency. A reanalysis of the observational data of Mischel and Peake revealed conceptually and empirically identifiable facets of the domain of conscientiousness and, when behaviors were properly aggregated, substantial evidence of their construct validity and cross-situational generality. This finding is contrary to interpretations of Mischel and Peake and occurred despite several definitional and measurement problems identified in their study. Conditions contributing to the prediction of behavior across situations are outlined. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Organizational commitment and job performance: It's the nature of the commitment that counts.

In this study, we examined relations between the performance of first-level managers in a large food service company and their affective commitment (i.e., emotional attachment to, identification with, and involvement in the organization), continuance commitment (i.e., perceived costs associated with leaving the company), and job satisfaction. Commitment and satisfaction scores were correlated with three indexes of performance obtained from the managers' immediate supervisors. As predicted, affective commitment correlated positively and continuance commitment correlated negatively with all three measures of performance. Job satisfaction did not correlate significantly with performance ratings. The findings are interpreted as illustrating the importance of distinguishing between commitment based on desire and commitment based on need and as supporting organizational efforts to foster affective commitment in their employees.

Poly(lactic acid)/pulp fiber composites: The effect of fiber surface modification and hydrothermal aging on viscoelastic and strength properties

Poly(lactic acid) (PLA)/kraft pulp fiber (30 wt%) composites were prepared with and without a coupling agent (epoxidized linseed oil, ELO, 1.5 wt%) by injection molding. The non-annealed composite samples, along with lean PLA, were exposed to two hydro-thermal conditions: cyclic 50% RH/90% RH at 23 and 50°C, both up to 42 days. The aging effects were observed by size exclusion chromatography, differential scanning calorimetry, dynamic and tensile mechanical analysis, and fracture surface imaging. ELO temporarily accelerated the material's internal transition from viscous to an increasingly elastic response during the aging at 50°C. ELO also slowed down the tensile strength reduction of the composites at 50°C. These observations were explained with the hydrophobic ELO molecules' coupling and plasticizing effects at fiber/matrix interfaces. No effects were observed at 23°C.     

Consensus in personality judgments: Moderating effects of target-rater acquaintanceship and behavior observability.

Conducted a peer rating study (N?=?111) to determine the effects of (a) level of acquaintanceship between rater and target and (b) degree of public observability of rated personality traits on peers' perceptions of target personality characteristics. As hypothesized, I found the agreement between peer ratings and target self-ratings to vary linearly and directly with acquaintanceship. In addition, acquaintanceship interacted with observability such that the public visibility of the behavior domain being judged was an important determinant of agreement for low to moderately acquainted peer dyads but not for highly acquainted dyads. Contrary to expectations, however, trait observability did not show a main effect with regard to self–peer agreement. The basis of the study is described with reference to the lens model of inferential behavior, and implications of the results are discussed with reference to past and future attempts at evaluating consensus and accuracy in person perception.

Hierarchical organization of personality and prediction of behavior.

Two studies evaluated personality trait measures and Big Five factor measures for their accuracy in predicting important behavior criteria. The results of both studies showed that the narrower traits and the broader factors, thought to define 2 levels of a hierarchy of personality variables, separately predicted most criterion variables. However, the incremental validity of the personality trait measures (the degree to which the traits increased the criterion prediction achieved by the factors) was generally much larger than the incremental validity of the Big Five factor measures. It was concluded that aggregating personality traits into their underlying personality factors could result in decreased predictive accuracy due to the loss of trait-specific but criterion-valid variance.

Robust output regulation and the preservation of polynomial closed‐loop stability

In this paper, we study the robust output regulation problem for distributed parameter systems with infinite‐dimensional exosystems. The main purpose of this paper is to demonstrate the several advantages of using a controller that achieves polynomial closed‐loop stability, instead of a one stabilizing the closed‐loop system strongly. In particular, the most serious unresolved issue related to strongly stabilizing controllers is that they do not possess any known robustness properties. In this paper, we apply recent results on the robustness of polynomial stability of semigroups to show that, on the other hand, many controllers achieving polynomial closed‐loop stability are robust with respect to large and easily identifiable classes of perturbations to the parameters of the plant. We construct an observer based feedback controller that stabilizes the closed‐loop system polynomially and solves the robust output regulation problem. Subsequently, we derive concrete conditions for finite rank perturbations of the plant's parameters to preserve the closed‐loop stability and the output regulation property. The theoretical results are illustrated with an example where we consider the problem of robust output tracking for a one‐dimensional heat equation.Copyright © 2013 John Wiley & Sons, Ltd.     

Teacher personality traits and student instructional ratings in six types of university courses.

Colleague ratings of 29 personality traits were studied in relation to student ratings of teaching effectiveness in a sample of 46 psychology teachers. Instructors were evaluated in six different types of university courses, ranging from freshman lecture classes to graduate research seminars. Major findings were as follows: (1) Rated teaching effectiveness varied substantially across different types of courses for a given instructor; (2) teaching effectiveness in each type of course could be predicted with considerable accuracy from colleague ratings of personality; and (3) the specific personality traits contributing to effective teaching differed markedly for different course types. It was concluded that psychology instructors tend to be differentially suited to different types of courses and furthermore that the compatibility of instructors to courses is determined in part by personality characteristics.
