It will be the function of this chapter to reveal the results of the relationships of the various abilities examined in Chapter II as measured by co-efficients of correlation, both of the zero and the first order (partial correlation). It will also deal in a limited degree with regression lines and equations.

The University

Emerging adulthood is one of the most important life stages for self and identity development. The present research tracked the development of implicit self-esteem during emerging adulthood at both the group and individual levels. We used the implicit association test to assess implicit self-esteem with the improved D score as the index. We surveyed 327 students each year from the beginning of their first year of university until their graduation, with an extra assessment run in the middle of the first year. First-order autoregressive structural equation modeling indicated that implicit self-esteem remained quite stable during the university years in terms of rank-order stability. Latent growth modeling showed that implicit self-esteem decreased slightly during the university years with females initially manifesting a higher level. These findings enrich our understanding of implicit self-esteem and its development as well as self-construction during emerging adulthood.

The problem of this investigation is to study some of the factors of success in first year algebra. The method of the investigation consisted chiefly of the administration of standardized tests which were given to 160 pupils in eight different classes of first year algebra in the Mathematics Department of the Proviso Township High School, Maywood, Ill.

Measurement Effort

To improve the limited degree of immersion of static binaural rendering for headphones, an increased measurement effort to obtain multiple-orientation binaural room impulse responses (MOBRIRs) is reasonable and enables dynamic variable-orientation rendering. We investigate the perceptual characteristics of dynamic rendering from MOBRIRs and test for the required angular resolution. Our first listening experiment shows that a resolution between 15 ∘ and 30 ∘ is sufficient to accomplish binaural rendering of high quality, regarding timbre, spatial mapping, and continuity. A more versatile alternative considers the separation of the room-dependent (RIR) from the listener-dependent head-related (HRIR) parts, and an efficient implementation thereof involves the measurement of a first-order Ambisonic RIR (ARIR) with a tetrahedral microphone. A resolution-enhanced ARIR can be obtained by an Ambisonic spatial decomposition method (ASDM) utilizing instantaneous direction of arrival estimation. ASDM permits dynamic rendering in higher-order Ambisonics, with the flexibility to render either using dummy-head or individualized HRIRs. Our comparative second listening experiment shows that 5th-order ASDM outperforms the MOBRIR rendering with resolutions coarser than 30 ∘ for all tested perceptual aspects. Both listening experiments are based on BRIRs and ARIRs measured in a studio environment.

Factors Of Success

Abstract Background The national ranking examination (NRE) marks the end of the second cycle (6th university year) of French medical studies and ranks students allowing them to choose their specialty and city of residency. We studied the potential predictive factors of success at the 2015 NRE by students attending a French School of Medicine. Methods From March 2016 to March 2017, a retrospective study of factors associated with the 2015 NRE success was conducted and enrolled 242 students who attended their sixth year at the school of medicine of Reims. Demographic and academic data collected by a home-made survey was studied using univariate and then multivariate analysis by generalized linear regression with a threshold of p <  0.05 deemed significant. Results The factors independently associated with a better ranking at the NRE were the motivation for the preparation of the NRE (gain of 3327 ± 527 places, p <  0.0001); to have participated in the NRE white test organized by la Revue du Praticien in November 2014 (gain of 869 ± 426 places, p <  0.04), to have participated in the NRE white test organized by la conférence Hippocrate in March 2015 (+ 613 places ±297, p <  0.04). The factors independently associated with poor NRE ranking were repeating the first year (loss of 1410 places ±286, p <  0.0001), repeating a year during university course (loss of 1092 places ±385, p <  0.005), attendance of hospital internships in 6th year (loss of 706 places ±298, p <  0.02). Conclusions The student motivation and their white tests completion were significantly associated with success at the NRE. Conversely, repeating a university year during their course and attendance of 6th year hospital internships were associated with a lower ranking.

The Relationship

In most species of ducks, only females tend the brood, and they do not defend brood territories. However, in buffleheads (Bucephala albeola), females strongly defend brood territories. I examined factors affecting territory size of broods, and their consequences for growth rate and survival of ducklings. Brood density tended to be higher on ponds with higher food density. Territory size was inversely correlated with both food abundance in the territory and brood density on the pond. The slope of the relationship between territory size and food did not differ significantly from −1, the slope expected if females adjust territory size to maintain a constant food supply. Partial correlation analysis, however, revealed that brood density may be a more important proximate determinant of territory size than food. Growth rates of ducklings were not affected by food density but were depressed at high brood density in one year. Duckling survival increased with food density in the first year but was depressed at high brood density in the next. I suggest that females select a brood territory and that the size of that territory varies according to both food and brood density. This apparently buffers the effects of variation in food and brood density on growth and survival of ducklings.

This research uses path analysis to determine the interrelationships among seed yield and 16 related Morphological traits. Eighty-one garden cress accessions from IPK (Department of Leibniz Institute of Plant Genetics and Crop Plant Research) were grown in two growing seasons (2012–13) to determine the important components of seed yield. Observations were recorded on 20 other canola traits. Correlation coefficient analysis revealed that seed yield was positively correlated with all traits except plant height (PH) in the first year and except main axis length (MAL) and PH in the second year. Sequential path analysis (SPA) identified the thousand-seed weight (TSW), number of siliques per plant (NSP) and height of first silique (HFS) as important first order traits influenced seed yield in first year. Plant height, NSP, and the TSW were important first-order traits that influenced seed yield in the second year. This indicates that breeding programs should be based on these traits for further improvement of the garden cress. All direct effects were significant, as indicated by bootstrap analysis. The results suggest that TSW and NSP could be used as a selection criterion in selecting for increased seed yield in garden cress.
