A meta-analysis of adult-rated child personality and academic performance in primary education

Background: Personality is reliably associated with academic performance, but personality measurement in primary education can be problematic. Young children find it difficult to accurately self-rate personality, and dominant models of adult personality may be inappropriate for children. Aims: This meta-analysis was conducted to determine the validity of the Five-Factor Model (FFM) of personality for statistically predicting children's academic performance. Sample: Literature search identified 12 reports, with cumulative sample sizes ranging from 4,382 (19 correlations) to 5,706 (23 correlations) for correlations with Emotional Stability and Conscientiousness respectively. Method: Hunter-Schmidt random effects meta-analysis was used and moderators were tested using sample-weighted regression. Results: When compared with self-rated measures, adult-rated Conscientiousness and Openness were more-strongly correlated with academic performance, but adult-rated Agreeableness was less-strongly correlated. Q-set based assessments had lower validity, which appeared to explain moderating effects of rating-source. Moderating effects were not found for age, year of education (grades 1 to 7), or language within which the study was conducted. Conclusions: Conscientiousness and Openness had two of the strongest correlations with academic performance yet reported, comparable with previous meta-analytic correlations of academic performance with instructional quality, cognitive ability, and feedback. The FFM appears to be valid for educational research with children. Openness, which has no counterpart in models of children's temperament, should be further researched with children. Future research should examine the measurement of childhood personality, its relationship to intelligence, the extent to which it is malleable in primary education, and its causal relationship with academic performance

Thinking bigger: The Cronbachian paradigm & personality theory integration

Personality theories largely mirror disparities between fundamental paradigms that guide most psychology: one based upon Galton's emphasis on inter-individual differences and the lexical hypothesis; the other inspired by Wundt is focused upon intra-individual processes, such as temperament and Reinforcement Sensitivity Theory. Previous integrations of personality models using these paradigms failed to account for observed variance, suggesting model incommensurability. We propose that a broader conception-developed from Cronbach and colleagues' generalisability theory-provides an effective integrating framework, and show how Galtonian and Wundtian models may be assimilated within Cronbachian approaches. Additionally, Cronbachian models have novel practical implications. Application of the Cronbachian paradigm to personality will be challenging, but provides an opportunity to achieve genuine coherence in personality research

Comparison of two European paediatric emergency departments: does primary care organisation influence emergency attendance?

Backround: To compare paediatric Emergency Department (ED) attendances and admission outcomes in twoEuropean hospitals with different paediatric primary care set-up. Methods: This is a retrospective prevalence study comparing all paediatric ED attendances during calendar years 2013 in two EDs with similar catchment area: one in Italy (Trieste) where paediatric primary care is provided by office paediatricians, the other, in the UK (Cambridge), where paediatric primary care is provided by general practitioners. Data on reason for presentation, discharge diagnosis and admission rate were collected and sub-group analysis for specific age groups (<1 year, 1 \u2013 4 years, 5 \u2013 15 years) was performed. Results: Over 12 months, 20.331 children (0 \u2013 15 years old) were seen in Cambridge and 18.646 in Trieste, with a very similar age distribution in both centres, except for the youngest age group: the percentage of infants seen in comparison with the total number of children attending ED was 1/3 higher in England than in Italy (15.4% vs 11. 4%). The reasons for attendance were similar: under 1 year of age, the chief complaints were fever, breathing difficulties and gastrointestinal problems while in the older age groups trauma represented the commonest reason. Among discharge diagnoses, no differences were found between the two hospitals, except for faltering growth and \u201c well child \u201d , more frequently diagnosed in English children under 5 years. The proportion of admissions was three times higher in Cambridge (14.1% vs 4.8%) with most children being admitted for infectious diseases. Conclusions: ED attendances in infants are more common in a primary care setting provided by general practicioner and, moreover, admission rates in all age groups are 1/3 reduced by primary care based paediatricians. Due to the methodological limits of this study, it isn't possible to evaluate whether these results depend only on paediatric primary care set-up or be determined by other confounding factors. New studies are needed to confirm this preliminary evidence

Pillole di clavic... ultura

The paper presents the cases of tree children with clavicular swelling and a different final diagnosis that offered the opportunity to discuss the key points for the differential diagnosis of clavicular swelling and to draw a rational diagnostic work-up underlining the decisive role of MRI. Although several causes (in order: Chronic Recurrent Multifocal Osteomyelitis, Ewing sarcoma, Tietze syndrome) of clavicular swelling are proposed, it is essential to highlight that main causes are represented by neoplastic and inflammatory causes. However, even if clinical and anamnestic assessment are suitable to disentangle from diagnostic incertitude, imaging is often useful to obtain a diagnosis, before (or even without) biopsy. It is anyway mandatory to rule out neoplasia in all non-traumatic clavicular swelling

Evidence for three factors of perfectionism: : Perfectionistic Strivings, Order, and Perfectionistic Concerns

The factor structure of perfectionism is inconsistent across models. Most models distinguish between adaptive and maladaptive aspects of perfectionism, but often do not include elements representing order. Order, however, is theoretically important and distinct from the broad adaptive perfectionism factor. Therefore, a three-factor model of perfectionism was tested in a sample of undergraduate students (N = 208) who completed the Almost Perfect Scale-Revised and the Frost Multidimensional Perfectionism Scale. According to the chi-squared difference test and CFI differences, model fit improved when repre- senting Order as a separate factor. In addition, Order and Perfectionistic Strivings factors showed signif- icantly different correlations with Conscientiousness and Neuroticism, academic performance expectation, and four achievement goal orientations, providing further evidence of their distinctiveness. Therefore, including Order as a separate factor represents a better model of perfectionism

Genome-wide analyses for personality traits identify six genomic loci and show correlations with psychiatric disorders

Personality is influenced by genetic and environmental factors1 and associated with mental health. However, the underlying genetic determinants are largely unknown. We identified six genetic loci, including five novel loci2,3, significantly associated with personality traits in a meta-analysis of genome-wide association studies (N = 123,132–260,861). Of these genomewide significant loci, extraversion was associated with variants in WSCD2 and near PCDH15, and neuroticism with variants on chromosome 8p23.1 and in L3MBTL2. We performed a principal component analysis to extract major dimensions underlying genetic variations among five personality traits and six psychiatric disorders (N = 5,422–18,759). The first genetic dimension separated personality traits and psychiatric disorders, except that neuroticism and openness to experience were clustered with the disorders. High genetic correlations were found between extraversion and attention-deficit– hyperactivity disorder (ADHD) and between openness and schizophrenia and bipolar disorder. The second genetic dimension was closely aligned with extraversion–introversion and grouped neuroticism with internalizing psychopathology (e.g., depression or anxiety)

Measurement of the Branching Fraction for B- --> D0 K*-

We present a measurement of the branching fraction for the decay B- --> D0 K*- using a sample of approximately 86 million BBbar pairs collected by the BaBar detector from e+e- collisions near the Y(4S) resonance. The D0 is detected through its decays to K- pi+, K- pi+ pi0 and K- pi+ pi- pi+, and the K*- through its decay to K0S pi-. We measure the branching fraction to be B.F.(B- --> D0 K*-)= (6.3 +/- 0.7(stat.) +/- 0.5(syst.)) x 10^{-4}.Comment: 7 pages, 1 postscript figure, submitted to Phys. Rev. D (Rapid Communications

A Study of Time-Dependent CP-Violating Asymmetries and Flavor Oscillations in Neutral B Decays at the Upsilon(4S)

We present a measurement of time-dependent CP-violating asymmetries in neutral B meson decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator Center. The data sample consists of 29.7 ${\rm fb}^{-1}$ recorded at the $\Upsilon(4S)$ resonance and 3.9 ${\rm fb}^{-1}$ off-resonance. One of the neutral B mesons, which are produced in pairs at the $\Upsilon(4S)$, is fully reconstructed in the CP decay modes $J/\psi K^0_S$, $\psi(2S) K^0_S$, $\chi_{c1} K^0_S$, $J/\psi K^{*0}$ ($K^{*0}\to K^0_S\pi^0$) and $J/\psi K^0_L$, or in flavor-eigenstate modes involving $D^{(*)}\pi/\rho/a_1$ and $J/\psi K^{*0}$ ($K^{*0}\to K^+\pi^-$). The flavor of the other neutral B meson is tagged at the time of its decay, mainly with the charge of identified leptons and kaons. The proper time elapsed between the decays is determined by measuring the distance between the decay vertices. A maximum-likelihood fit to this flavor eigenstate sample finds $\Delta m_d = 0.516\pm 0.016 {\rm (stat)} \pm 0.010 {\rm (syst)} {\rm ps}^{-1}$. The value of the asymmetry amplitude $\sin2\beta$ is determined from a simultaneous maximum-likelihood fit to the time-difference distribution of the flavor-eigenstate sample and about 642 tagged $B^0$ decays in the CP-eigenstate modes. We find $\sin2\beta=0.59\pm 0.14 {\rm (stat)} \pm 0.05 {\rm (syst)}$, demonstrating that CP violation exists in the neutral B meson system.

Study of e+e- --> pi+ pi- pi0 process using initial state radiation with BABAR

The process e+e- --> pi+ pi- pi0 gamma has been studied at a center-of-mass energy near the Y(4S) resonance using a 89.3 fb-1 data sample collected with the BaBar detector at the PEP-II collider. From the measured 3pi mass spectrum we have obtained the products of branching fractions for the omega and phi mesons, B(omega --> e+e-)B(omega --> 3pi)=(6.70 +/- 0.06 +/- 0.27)10-5 and B(phi --> e+e-)B(phi --> 3pi)=(4.30 +/- 0.08 +/- 0.21)10-5, and evaluated the e+e- --> pi+ pi- pi0 cross section for the e+e- center-of-mass energy range 1.05 to 3.00 GeV. About 900 e+e- --> J/psi gamma --> pi+ pi- pi0 gamma events have been selected and the branching fraction B(J/psi --> pi+ pi- pi0)=(2.18 +/- 0.19)% has been measured.Comment: 21 pages, 37 postscript figues, submitted to Phys.
