Husserl’s Conception of Physical Theories and Physical Geometry in the Time of the Prolegomena: A Comparison with Duhem’s and Poincaré’s Views

This paper discusses Husserl’s views on physical theories in the first volume of his Logical Investigations, and compares them with those of his contemporaries Pierre Duhem and Henri Poincaré. Poincaré’s views serve as a bridge to a discussion of Husserl’s almost unknown views on physical geometry from about 1890 on, which in comparison even with Poincaré’s—not to say Frege’s—or almost any other philosopher of his time, represented a rupture with the philosophical tradition and were much more in tune with the physical geometry underlying the Einstein-Hilbert general theory of relativity developed more than two decades later.     

Transfer of spatial behaviour controlled by a landmark array with a distinctive shape

In two experiments, rats swam to a submerged platform in one corner of a rectangular or kite-shaped array created by four identical landmarks attached to the walls of a circular pool. After training in the rectangular array, rats expressed a preference for the corner in the kite-shaped array that was geometrically equivalent to where the platform was located previously. After training in either array, the removal of two landmarks from the rectangular array, or the landmark at the apex of the kite-shaped array, did not affect the control over searching exerted by the remaining landmarks. The results imply that rats use local rather than global spatial representations when searching for a hidden goal with reference to an array of landmarks.     

Cognition and daily activities in a general population sample aged +55

ABSTRACT

Objective: We tested the association of individual cognitive domains measured with the Mini-Mental State Examination (MMSE) and disability.

Method: Cross-sectional study in a population-based cohort aged ≥55 years (n = 4,803). Sample was divided into two groups: individuals with cognition within the normal range (CNR) (n = 4,057) and those with cognitive impairment (CI) (n = 746). Main outcome measures: The MMSE, the Katz Index (Basic Activities of Daily Living, bADL), the Lawton and Brody Scale (Instrumental Activities of Daily Living, iADL), and the Geriatric Mental State (GMS-AGECAT).

Results: MMSE-orientation was associated with disability in bADL, iADL and a decrease in social participation, regardless of cognitive status. MMSE-attention was associated with disability in iADL, but only in CNR. MMSE-language was associated with disability in bADL, iADL and with reduced social participation, but only in CI. Conclusions: The associations observed between disability and orientation may have clinical and public health implications.     

Confirmatory factor analysis of the five-item version of the Francis scale of attitude towards Christianity in adolescent students

ABSTRACT

The brief scale of Francis for religiosity (Francis-5) has shown acceptable psychometric performance in Colombian adolescents. However, a confirmatory factorial analysis (CFA) has not been performed. The objective of the researche was to make a CFA to the Francis-5 in a sample of students of Santa Marta, Colombia. A validation study was performed. 350 students between 10 and 17 years old, and 54% were female. A CFA was performed to test the dimensionality of different versions of five and four items of the scale. Authors calculated five goodness of fit indexes indices (Chi square, RMSEA, CFI, TLI, and SMSR). The Francis-5 presented as goodness-of-fit coefficients, chi squared = 18.5, gl = 5, p = .002, RMSEA = .09 (CI90% .05 to .13), CFI = .99, TLI = .99, and SMSR = .01. And the version with the best coefficients of goodness was the Francis-5 without the fourth item (‘Pray helps me a lot’) with chi squared = .55, gl = 2, p = .76, RMSEA = .00 (CI90% .00 to .07), CFI = 1.00, TLI = 1.00, and SMSR = .01. As conclusions, the dimensionality of the Francis-5 is questionable. For a version without the item 4 the data are better fit.     

Family Functioning, Identity, and Problem Behavior in Hispanic Immigrant Early Adolescents

The present study investigated the role of identity in the relationship between family functioning and behavior problems in a sample of Hispanic immigrant early adolescents and their families. The sample consisted of 181 Hispanic immigrant adolescents (92 males, 89 females) and their participating caregivers (who were mostly mothers). Identity was measured using adolescent reports, whereas family functioning and early adolescent behavior problems were measured using both adolescent and parent reports. Correlational analyses indicated that previously obtained relationships among family functioning, identity, and behavior problems were replicated in the present sample. Structural equation models indicated that 20% of the relationship between family functioning and behavior problems operated indirectly through identity, and identity confusion partially mediates the relationship between family functioning and early adolescent behavior problems. Implications for intervention are discussed.
