Gifted underachievers perform worse in school than would be expected based on their high intelligence. Possible causes for underachievement are low motivational dispositions (need for cognition) and metacognitive competences. This study tested the interplay of these variables longitudinally with gifted and non-gifted students from Germany (N = 341, 137 females) in Grades 6 (M = 12.02 years at t1) and 8 (M = 14.07 years). Declarative and procedural metacognitive competences were assessed in the domain of reading comprehension. Path analyses showed incremental effects of procedural metacognition over and above intelligence on the development of school achievement in gifted students (β = .139). Moreover, declarative metacognition and need for cognition interactively predicted procedural metacognition (β = .169), which mediated their effect on school achievement.  相似文献

In this paper we report upon a first empirical exploration of the relative efficiency of innovation development by product users vs. product producers. In a study of over 50 years of product innovation in the whitewater kayaking field, we find users in aggregate were approximately 3× more efficient at developing important kayaking product innovations than were producers in aggregate. We speculate that this result is driven by what we term “efficiencies of scope” in problem-solving. These can favor an aggregation of many user innovators, each spending a little, over fewer producer innovators benefitting from higher economies of scale in product development. We also note that the present study explores only one initial point on what is likely to be a complex efficiency landscape.  相似文献

Objective

We examined (1) the prevalence of childhood sexual abuse (CSA) experiences as a function of cohort and gender, (2) the prevalence of factors associated with CSA as a function of cohort and whether the association of these factors with CSA remained the same irrespective of cohort, and (3) whether any cohort differences could be explainable by cohort differences in reporting bias.

Method

We used the responses of 4,561 men (M = 29, SD = 7 years) and 8,361 female (M = 29, SD = 7 years) Finnish participants who responded to the Childhood Trauma Questionnaire-Short Form as well as questions regarding family structure.

Results

The prevalence of CSA experiences varied between 0.7-4.6% for men and 1.8-7.5% for women depending on the item. Younger cohorts reported less CSA as well as less of the risk factors (physical neglect and abuse, emotional neglect and abuse, parental substances abuse, not growing up with both biological parents) that were positively associated with the likelihood of CSA. The effects of these risk factors did not vary as a function of the cohort. Also, the declining trend was not explainable by social desirability being higher in the younger cohorts.

Conclusions

The results suggest that there is a real decline in the prevalence of CSA and it is associated with a simultaneous decline in factors associated with CSA.  相似文献

Research in information processing suggests that the journalistic practice of embedding right-wing populist Twitter posts in news may stimulate political polarization. To test this notion, we conducted an online experiment (N?=?379). We investigated how highlighted right-wing populist statements affected individuals from different ideological stances and whether potential effects were determined by Twitter-specific characteristics (Twitter frame, profile picture). We exposed participants to two articles, each including a statement by a politician of the Austrian Freedom Party. In the first group, the statements were not highlighted (control group). In the second and third group, the statements appeared as conventional block quotes either without (G2) or with (G3) a picture of the politician. In the fourth and fifth group, the statements were highlighted as Twitter posts, again either without (G4) or with (G5) a picture of the politician. Results revealed that all highlighting conditions increased statement recognition among left-wing individuals. However, the full Twitter post condition exerted the strongest effect. Higher recognition then decreased left-wing individuals’ anti-immigrant attitudes and sympathy toward the right-wing populist candidate. Thus, embedding right-wing populists’ Twitter posts may induce disconfirmation bias among left-wing voters and trigger a process in which they strengthen their initial attitudes.  相似文献

Many services can be self-provided. An individual user or a user firm can, for example, choose to do its own accounting - choose to self-provide that service - instead of hiring an accounting firm to provide it. Since users can ‘serve themselves’ in many cases, it is reasonable to suspect that they can also innovate with respect to the services they self-provide - possibly without the assistance of service providers.In this paper, we conduct the first quantitative exploration of the importance of services innovation by users, focusing on the field of commercial and retail banking services. We find that 55% of today's computerized commercial banking services were first developed and implemented by non-bank firms for their own use, and 44% of today's computerized retail banking services were first developed and implemented by individual service users rather than by commercial financial service providers. Manual precursors to these services - manual procedures that carried out functions similar to computerized services in our sample - were almost always developed by users as self-services.Our empirical findings differ significantly from prevalent producer-centered views of service development. We speculate that the patterns we have observed in banking with respect to the major role of users in service development will prove to be quite general. If so, this will be an important matter: on the order of 75% of GDP in advanced economies today is derived from services. We discuss the implications of our findings for research and practice in service development.  相似文献

Question:

Can e-readers loaded with medical textbooks and other relevant material benefit medical students, residents, and preceptors in clinical settings?

Settings:

The settings are North Carolina community clinics served by Duke University Medical Center and St. Joseph''s Hospital in Bryan, Texas, and Scott and White Memorial Hospital in Temple, Texas.

Methods:

Duke University: Twenty second-year medical students and fourteen family medicine clerkship preceptors used Kindle e-readers in clinics during eight months of rotations. Students and preceptors provided feedback through an anonymous online survey. Texas A&M University: Nine fourth-year medical students in an elective compared medical textbooks in print, online, and on a Kindle. Six residents at a local hospital completed an anonymous online survey after a three-week loan of a Kindle loaded with medical textbooks.

Results:

The e-reader''s major advantages in clinical settings are portability and searchability. The selected e-reader''s limitations include connection speed, navigation, and display. User preferences varied, but online resources were preferred. Participants suggested additional uses for Kindles in medical education.

Conclusions:

The selected e-reader''s limitations may be resolved with further development of the device. Investigation of other e-readers is needed. Criteria for evaluating e-readers in clinical settings should include portability, searchability, speed, navigation, and display. Research comparing e-readers and mobile devices in clinical education is also warranted.  相似文献

Foreign firms patent in emerging economies with weak appropriability regimes at an increasing rate. This phenomenon constitutes a paradox since in such a setting foreign firms should have weak incentives to patent. In an attempt to resolve this paradox, we conducted an inductive analysis of 11 foreign firms that patent in such a setting, using the case of China as our empirical context. We identify four archetypes of foreign firms and three key antecedents the interaction of which determines which archetype a firm can be subsumed under.Our study complements the developed-economy focus of the extant appropriation literature by adding an international perspective. We extend previous econometric studies by identifying salient factors on the firm level that determine the extent to which a foreign firm patents in emerging economies with a weak appropriability regime, highlighting that the extent of a firm's motivation to maintain its freedom to operate can supersede imitability concerns. We also comment on the practical implications of these contributions for managers of foreign firms. Highlighting a structural conflict of interest between foreign firms from developed economies and the development goals of an emerging economy, we point to the generalizability of our results to a wide range of other emerging economies worldwide.  相似文献

This study explored the relationship between Adlerian themes, gender, and ethnicity. Results indicate significant differences between Hispanic and Caucasian (non-Hispanic) community college students in Belonging and Social Interest as measured by the BASIS-A. Differences between males and females in Going Along and Wanting Recognition are also explored. The findings are discussed in relation to college students, teaching, and classroom climates.  相似文献

The expansion in the number of people entering higher education has resulted in a substantial increase in the proportion of students enrolling in nontraditional modes, such as part-time study. This study examined the question of whether part-time study curtails the development of the types of intellectual capabilities needed for a knowledge-based economy, because the students would have markedly less exposure to a stimulating campus environment than their full-time counterparts. Graduates from discrete full- and part-time programs from 1 university in Hong Kong completed a survey seeking perceptions of the nurturing of a range of capabilities, together with measures of teacher-student relationships and type of teaching experienced. Two hypotheses were tested by structural equation modeling: (a) the same mechanism for capability development operated for full- and part-time modes and (b) the principal element of the mechanism was the nature of teaching and the quality of teacher-student interaction. Hypothesis 1 was supported because configural invariance between hypothesized models for capability development between the 2 modes was found. Hypothesis 2 was also supported because the models showed that the principal influence on capability development came from teaching for understanding, through promoting active learning experiences and the degree and quality of teacher-student interaction.  相似文献
