Can a non-specific bias toward top-heavy patterns explain newborns' face preference?
No full textThis study examined newborns’ face preference using
images of natural and scrambled faces in which the location
of the inner features was distorted. The results demonstrate that
newborns’ face preference is not confined to schematic configurations, but can be obtained also with veridical faces. Moreover, this phenomenon is not produced by a specific bias toward the face geometry, but derives from a domain-general bias toward configurations with more elements in the upper than in the
lower half (i.e., top-heavy patterns). These results suggest that
it may be unnecessary to assume the existence of a prewired
tendency to orient toward the face geometry, and support the
idea that faces do not possess a special status in newborns’ visual
world
What are the causes of educational inequality and of its evolution over time in Europe? Evidence from PISA
No full textThis paper provides evidence on the sources of differences in inequality in educational scores and their evolution over time in four European countries. Using Programme for International Student Assessment data from the 2000 and the 2006 waves, the paper shows that inequality decreased in Germany and Spain (two ‘decentralised’ schooling systems), whilst it increased in France and Italy (two ‘centralised’ systems). The decomposition exercise shows that educational inequality not only does reflect the background related inequality, but also schools' characteristics especially. These characteristics are responsible for the observed evolution over time of inequality
The origins of face perception: Specific vs. non-specific mechanisms
No full textMany studies have demonstrated that newborns prefer upright faces over upside-down faces. Based on this evidence, some have suggested that faces represent a special class of stimuli for newborns and there is a qualitative difference between the processes involved in perception of facelike and non-facelike patterns (i.e. structural hypothesis). Others suggest that there is no reason to suppose that faces are different from other patterns, because faces, like any other class of visual stimuli, are subject to filtering by the properties of the visual system (i.e. sensory hypothesis). The core question that will be addressed in the present paper is whether, to manifest itself, face preference requires the unique structure of the face, represented by the relative spatial location of its internal features, or rather some more general properties that other stimuli may also possess. Evidence will be presented supporting the idea that newborns do not respond to facelike stimuli by 'facedness' but, rather, by some general structural characteristics that best satisfy the constraints of the immature visual system.

A Smile Enhances 3-Month-Olds' Recognition of an Individual Face
No full textRecent studies demonstrated that in adults and children recognition of face identity and facial expression mutually interact (Bate, Haslam, & Hodgson, 2009; Spangler, Schwarzer, Korell, & Maier-Karius, 2010). Here, using a familiarization paradigm, we explored the relation between these processes in early infancy, investigating whether 3-month-old infants' ability to recognize an individual face is affected by the positive (happiness) or neutral emotional expression displayed. Results indicated that infants' face recognition appears enhanced when faces display a happy emotional expression, suggesting the presence of a mutual interaction between face identity and emotion recognition as early as 3 months of age
Primary “amyloid tumor” of the mammary gland in a dog
No full textThe present report describes an unusual mammary lesion in a dog, with gross and histological features
similar to the lesion known as “amyloid tumor of the breast” in the woman.
A fourteen year-old female spayed Dalmatian dog was presented to the practitioner with a large, bilobated
lump involving left and right IV mammary gland. The mass was surgically excised and submitted for
histopathological examination.
Grossly, two large subcutaneous nodular, firm masses, merging on the median line, expanded left and right
IV mammary glands. Histologically, masses were encapsulated and mainly composed of large, coalescing
lakes of pale eosinophilic, homogenous hyaline amorphous material, that stained positive with Congo Red
(amyloid). Numerous plasma cells with moderate anysocytosis and anysokariosis and rare mitoses were
multifocally recognizable. Multinucleated giant cells (MNGCs) with nuclear features similar to plasma cells
were occasionally present. Moreover, MNGCs with scant eosinophilic cytoplasm and up to 25 dense nuclei
were visible closely associated with amyloid deposits. Moderately atrophic mammary parenchyma was
present at periphery. Immunohistochemistry (ABC method) was performed to characterize MNGCs and
amyloid, applying anti-Lysozyme; Lambda-light-immunoglobulin-chains and HLA antibodies. Plasma cells
and MNGCs were Lysozyme and HLA negative. Lambda-chains stained plasma cells, the majority of MNGCs
and amyloid (AL amyloid).
Bilateral mammary extramedullary plasmacytoma with abundant AL amyloid deposition was diagnosed.
Clinical workup did not reveal systemic amyloidosis or multiple myeloma. Sixteen months later the dog was
humanely killed because of cardiac failure. No signs of multiple myeloma or recurrence of the tumor were
reported.
Primary amyloidosis of the breast not associated with mammary carcinoma (amyloidoma), is a rare entity
that has been documented in women since 1973, affecting mostly elderly patients, with bilateral
involvement and related neither to systemic amyloidosis nor to multiple myeloma. Despite similar gross
and histological appearance, some cases have been described as primary amyloidosis, while others as
plasmacytoma with massive amyloid deposition
In the canine species, mammary gland amyloid deposition was described in association with mammary
carcinoma whereas mammary primary amyloidosis or plasmacytoma with massive amyloid deposition have
never been reported so far. To the best of author’s knowledge this is the first report in the dog of a bilateral
mammary extramedullary plasmacytoma with features consistent with primary amyloidoma of the breast
in the woman
