From a comprehensive study of the public addresses of Woodrow Wilson in the period following the outbreak of the war in Europe in August 1914 to the war's conclusion in June 1919, this essay examines Wilson's transformation of the long-held vision of America as merely a great example of liberty to its embodiment as the self-sacrificing champion of liberty. It will demonstrate how this transformation of the American "self" was inextricably connected to a changing image of the war and the construction of an enemy image of the German government.

The psychometric properties of the Rosenberg Self-Esteem Scale (RSES) as a clinical research instrument for acute coronary syndrome (ACS) patients were investigated in a translated Chinese version of the instrument. A confirmatory factor analysis was conducted on the RSES to establish its psychometric properties in 128 ACS patients over two observation points (within 1 week and 6 months post-admission for ACS). Internal and test - retest reliability of the RSES-TOT (all-items) and RSES-POS sub-scale (positively valenced items) were found to be acceptable. The RSES-NEG sub-scale (negatively valenced items) lacked acceptable internal reliability. The underlying factor structure of the RSES comprised two distinct but related factors, though there was inconsistency in best model fit indices at the 1-week observation point. The use of the RSES as two sub-scales (RSES-POS and RSES-NEG) may be clinically useful in evaluating the influence of this important psychological construct on the health outcomes of patients with ACS. Directions for future research are indicated.

Thomas Merton pursued a life-long quest to grasp the nature of the “true self.” This is the self that lives in and through Christ. Opposed to this is the false self that is expressive of infidelity. It is argued that the interaction between the true and false selves constitutes a dialogical process. The thesis of the essay is that this interaction expresses the dynamics associated with what some psychologists refer to as the “dialogical self.” The dialogical self is a model of the inner life that draws attention to the interpretive process required to deal with the many voices that get internalized in an engagement with the world.

Despite the expense associated with rehabilitation following stroke, dissatisfaction with psychosocial outcomes is common (Thomas & Parry, 1996). The rehabilitation system has been critiqued as lacking a theoretical base for psychosocial interventions (Goldberg, Segal, Berk, Schall, & Gershkoff, 1997). The current paper examines the possible role of the Chronic Disease Self-Management Program ([CDSMP] Lorig, 1996) in contributing to the psychosocial rehabilitation of people with stroke. This paper focuses on the analysis of incidental comments made by participants about a version of the CDSMP, tailored for people with stroke. These comments, collected over an 18-month follow-up period, provide interesting insights into the key aspects of the program. Six informative themes emerged from the more specific comments, namely (1) the importance of social contact and comparison, (2) increased awareness and knowledge about stroke, (3) motivation to pursue goals and activities, (4) a sense of achievement, (5) maintenance of gains, and (6) the paradoxical nature of social support. According to participants, the program was associated with enhanced self-efficacy. Other reported benefits (such as social support and enhanced knowledge) were indirectly associated with the program and appeared to reflect social aspects of the group and its stroke-specific focus. Maintenance of gains made by participants was seen as a crucial issue.

Shihāb al-Dīn Suhrawardī (d.687/1191) proposed a theory of apperception that constitutes the core of his “illuminative” epistemology. His theory of apperception purports to account for the soul’s immediate, reflexive, and unmediated knowledge of its own essence. Apperception may be defined as the direct experience the soul has of its essence. A closer examination of the Avicennan tradition (Avicenna died in 420/1037) reveals the existence of a number of arguments for the demonstration of an apperception of the self/soul similar to the arguments Suhrawardī later proposes. Contrary to admitted views, Avicenna had tackled issues related to the soul’s apperception, a type of perception distinct from the soul’s intellection of its essence. Avicenna alluded to the existence of a mode of perception specific to the soul that would guarantee both the soul’s unity and its personal identity. This apperception is defined as an unmediated presence of the soul to itself. These elements recur in Suhrawardī’s theory of apperception and numerous versions of Avicenna’s arguments for the demonstration of the presential nature of apperception

A detailed study has been carried out on the dependence of folate binding on the concentration of FBP (folate-binding protein) at pH 5.0, conditions selected to prevent complications arising from the pre-existing self-association of the acceptor. In contrast with the mandatory requirement that reversible interaction of ligand with a single acceptor site should exhibit a unique, rectangular hyperbolic binding curve, results obtained by ultrafiltration for the FBP-folate system required description in terms of (i) a sigmoidal relationship between concentrations of bound and free folate and (ii) an inverse dependence of affinity on FBP concentration. These findings have been attributed to the difficulties in determining the free ligand concentration in the FBP-folate mixtures for which reaction is essentially stoichiometric. This explanation also accounts for the similar published behaviour of the FBP-folate system at neutral pH, which had been attributed erroneously to acceptor self-association, a phenomenon incompatible with the experimental findings because of its prediction of a greater affinity for folate with increasing FBP concentration.

This article examines the influence of culture on the way managers and workers perceive causes of success and failure in organizational tasks. The author argues that selfserving and actor-observer biases, as well as other attribution errors, will be moderated by culture. Specifically, managers and workers with a sociocentric self-concept from high-context cultures may be biased toward external attributions, while managers from low-context cultures with an idiocentric self-concept have a tendency to make more internal attributions. These variations in attributions have consequences that affect both managers and workers. Theoretical propositions and implications for international management practices are discussed. © 2005 Wiley Periodicals, Inc.

Samples from New Zealand and Australia have been tested in an adiabatic oven to assess the effect of rank on the R-70 selfheating rate of coal. A non-linear relationship can be defined for coals from both countries using the revised Suggate rank (S-r) parameter. Subbituminous coals have the highest R-70 self-heating rate values, which are 20 times that of high volatile A bituminous coals on a dry mineral matter free basis (similar to 1 cf. 20 degrees C h(-1)). However, the moderating effects of moisture and mineral matter can reduce this difference to only 2-3 times for coal in-situ. (c) 2005 Elsevier B.V All rights reserved.

Researchers in leadership effectiveness are paying increasing attention to the role of follower self-concept and identity as a mediator and moderator of the effectiveness of leadership. In this introductory article, we provide a short outline of this rapidly growing field of research, briefly introduce the articles presented in this special issue on leadership, self, and identity, and highlight key themes for future research that we feel emerge from these studies. These themes include greater attention to the dynamic interplay between leaders and followers, the incorporation of theories of fairness, and the role of leader self-concept. (c) 2005 Elsevier Inc.

This research used resource allocation theory to generate predictions regarding dynamic relationships between self-efficacy and task performance from 2 levels of analysis and specificity. Participants were given multiple trials of practice on an air traffic control task. Measures of task-specific self-efficacy and performance were taken at repeated intervals. The authors used multilevel analysis to demonstrate differential and dynamic effects. As predicted, task-specific self-efficacy was negatively associated with task performance at the within-person level. On the other hand, average levels of task-specific self-efficacy were positively related to performance at the between-persons level and mediated the effect of general self-efficacy. The key findings from this research relate to dynamic effects - these results show that self-efficacy effects can change over time, but it depends on the level of analysis and specificity at which self-efficacy is conceptualized. These novel findings emphasize the importance of conceptualizing self-efficacy within a multilevel and multispecificity framework and make a significant contribution to understanding the way this construct relates to task performance.

The self-rating Dysexecutive Questionnaire (DEX-S) is a recently developed standardized self-report measure of behavioral difficulties associated with executive functioning such as impulsivity, inhibition, control, monitoring, and planning. Few studies have examined its construct validity, particularly for its potential wider use across a variety of clinical and nonclinical populations. This study examines the factor structure of the DEX-S questionnaire using a sample of nonclinical (N = 293) and clinical (N = 49) participants. A series of factor analyses were evaluated to determine the best factor solution for this scale. This was found to be a 4-factor solution with factors best described as inhibition, intention, social regulation, and abstract problem solving. The first 2 factors replicate factors from the 5-factor solutions found in previous studies that examined specific subpopulations. Although further research is needed to evaluate the factor structure within a range of subpopulations, this study supports the view that the DEX has the factor structure sufficient for its use in a wider context than only with neurological or head-injured patients. Overall, a 4-factor solution is recommended as the most stable and parsimonious solution in the wider context.

Through a prospective study of 70 youths staying at homeless-youth shelters, the authors tested the utility of I. Ajzen's (1991) theory of planned behavior (TPB), by comparing the constructs of self-efficacy with perceived behavioral control (PBC), in predicting people's rule-following behavior during shelter stays. They performed the 1st wave of data collection through a questionnaire assessing the standard TPB components of attitudes, subjective norms, PBC, and behavioral intentions in relation to following the set rules at youth shelters. Further, they distinguished between items assessing PBC (or perceived control) and those reflecting self-efficacy (or perceived difficulty). At the completion of each youth's stay at the shelter, shelter staff rated the rule adherence for that participant. Regression analyses revealed some support for the TPB in that subjective norm was a significant predictor of intentions. However, self-efficacy emerged as the strongest predictor of intentions and was the only significant predictor of rule-following behavior. Thus, the results of the present study indicate the possibility that self-efficacy is integral to predicting rule adherence within this context and reaffirm the importance of incorporating notions of people's perceived ease or difficulty in performing actions in models of attitude-behavior prediction.
