Within the last few decades there has been a push to identify students who have or who are at-risk for learning disabilities as early as possible. Much of this recent focus is related to research showing the positive long-term benefits of early education for the general population and children in poverty, as well as to educational theory about early educational interventions. However, little to no research has been conducted on the long-term effects of age of first service provision for students with learning disabilities. Whether students with learning disabilities are doing better academically in high school or graduating high school at higher rates based on when they are identified or when they received services is yet to be known. This study analyzed data collected from families and schools for 2,000 youth with learning disabilities from the National Longitudinal Transition Study 2 (NLTS2), a study that investigated a nationally representative sample of approximately 12,000 students with disabilities. The present study used latent variable structural equation modeling (SEM) to investigate the effects of age of first service provision on high school educational achievement and high school graduation in order to better understand the long-term effects of the age of intervention for students with learning disabilities. Contrary to what was hypothesized, the age a student first received services for a learning disability did not statistically significantly affect his or her grades in high school or likelihood of graduating from high school. The age a student first received services for a learning disability was statistically significantly and positively related to standardized achievement tests in high school; however, the direction of causation was counter to what was hypothesized. Students who received services at a later age performed better on high school standardized achievement tests. An important limitation of these data is that measures of a student's cognitive abilities or the severity of a student's learning disability were not available for use in these analyses. Further limitations and possible implications of these findings are discussed. / text

Purpose: The purpose of this paper is to examine how age and job identification affect entrepreneurial intention. Design/methodology/approach: The researchers draw on a representative sample of the Austrian adult workforce and apply binary logistic regression on entrepreneurial intention. Findings: The findings reveal that as employees age they are less inclined to act entrepreneurially, and that their entrepreneurial intention is lower the more they identify with their job. Whereas gender, education, and previous entrepreneurial experience matter, leadership and having entrepreneurial parents seem to have no impact on the entrepreneurial intention of employees. Research implications: Implications relate to a contingency perspective on entrepreneurial intention where the impact of age is exacerbated by stronger identification with the job. Practical implications: Practical implications include the need to account for different motivational backgrounds when addressing entrepreneurial employees of different ages. Societal implications include the need to adopt an age perspective to foster entrepreneurial intentions within established organizations. Originality/value: While the study corroborates and extends findings from entrepreneurial intention research, it contributes new empirical insights to the age and job - dependent contingency perspective on entrepreneurial intention.

Au regard des problématiques sanitaires, économiques et environnementales liées à l'augmentation de la population âgée au cours des prochaines décennies, l'identification des déterminants du maintien ou de la dégradation de l'état de santé physique lors de l'avancée en âge représente un enjeu de santé publique majeur. Un consensus existe sur la relation entre les traits de personnalité définis par le Modèle en Cinq Facteurs (MCF, Digman, 1990), et la santé physique des seniors. Toutefois, peu de travaux ont identifié les processus sous-tendant cette relation. Sur la base d'un programme de recherche composé de cinq études, ce travail doctoral avait pour objectif de contribuer aux connaissances existantes, par l'identification d'un certain nombre de facteurs susceptibles de moduler et d'expliquer la contribution des traits de personnalité sur des indicateurs de santé physique lors de l'avancée en âge. Ce travail a permis la mise en évidence du rôle modérateur de l'âge chronologique dans la contribution de certains traits de personnalité, et principalement l'ouverture aux expériences, sur la santé perçue (étude 1), qui s'avère dépendant de l'état de santé objectif des individus (étude 2). De plus, la contribution de la personnalité sur des indicateurs de santé physique chez les seniors n'est pas activée par l'exposition aux stéréotypes liés à l'âge (étude 3). Par ailleurs, ce travail confirme la relation entre l'ouverture aux expériences et la tendance au rajeunissement, qui est reconnue comme étant un facteur de protection de l'état de santé lors de l'avancée en âge, et met en évidence le rôle médiateur d'une faible identification au groupe d'âge dans cette association (étude 4). Cette dissociation du groupe d'âge et le biais de rajeunissement associés à l'ouverture aux expériences semblent se manifester indépendamment du contexte et de l'environnement dans lequel la personne âgée évolue (étude 5). Ce travail doctoral permet donc un approfondissement des mécanismes qui sous-tendent la contribution des traits de personnalité sur la santé physique lors de l'avancée en âge, et contribue à une littérature relativement récente et en expansion insistant sur les implications de l'ouverture aux expériences pour la santé et le fonctionnement global des seniors. / Given the economic, environmental, and health issues related to the increasing number of people over 65 years in the coming decades, the identification of the factors associated with the maintenance or the degradation of physical health with advancing age is a major public health concern. Personality, as defined by the Five-Factors Model (FFM, Digman, 1990), is consistently associated with physical health in old age. However, few studies have focused on the underlying mechanisms of this relation. Based upon a five studies research program, the present doctoral dissertation aimed to contribute to current knowledge by identifying a number of factors which may modulate and explain the contribution of personality traits on markers of physical health with advancing age. This research revealed a moderating role of chronological age in the relation between personality, and openness to experiences in particular, and perceived health (study 1), which appeared to be dependent upon disease burden (study 2). Moreover, the contribution of personality on markers of physical health does not seem to be activated by the exposure to age-related stereotype (study 3). Finally, the present doctoral project confirmed the relation between openness to experience and a youthful subjective age, which is a recognized protective factor for physical health in old age, and identified the mediating role of age-group dissociation in this relationship (study 4). The tendencies to dissociate oneself from one's age group and to feel younger among open older people seem to be independent of the context and the environment (study 5). This doctoral dissertation contributes to an in-depth understanding of the mechanisms underlying the contribution of personality traits on physical health with advancing age, and adds to a growing body of research emphasizing the implications of openness to experience for global health and functioning of older people.
