Null subjects in generative grammar: A synchronic and diachronic perspective

2018

This book considers the null-subject phenomenon, whereby some languages lack an overtly realized referential subject in specific contexts. In generative syntax-the approach adopted in this volume-the phenomenon has traditionally been explained in terms of a ‘pro-drop’ parameter with associated cluster properties; more recently, however, it has become clear that pro-drop phenomena do not always correlate with all the initially predicted cluster properties. This volume returns to the centre of the debate surrounding the empirical phenomena associated with null subjects. Experts in the field explore the cluster properties associated with pro-drop; the types of null category involved in null-su…

Sociolinguistic variation of mitigating mechanisms: usage differences according to age and sex

2018

El presente artículo estudia la variación sociolingüística del fenómeno pragmático de la mitigación en las variables sociales de edad y sexo en el corpus PRESEEA-Valencia. En concreto, se centra en las diferencias cuantitativas y cualitativas en el empleo de mecanismos lingüísticos mitigadores y en las funciones de mitigación. Se analiza todo el sociolecto alto (Gómez Molina et alii 2001), que corresponde a 24 entrevistas semiformales (720 minutos), distribuidas proporcionalmente en tres grupos de edad (20-34 años; 35-55 años; 55 años en adelante) y en dos sexos (mujeres y hombres).El total de actos de habla mitigados en el corpus es de 960 y el número de mecanismos mitigadores es de 1838. …

Elucidating geological and biological processes underlying the diversification of Sulawesi tarsiers.

2009

Because of their exceptionally long independent evolution, a range diminution of their Eocene relatives, and a remarkable subsequent diversification in Southeast Asia, tarsiers are of particular importance to evolutionary primatologists. Little is known, however, on the processes shaping the radiation of these small enigmatic primates—especially on the Indonesian island of Sulawesi, their center of endemism. Geological reconstructions and progress in applying DNA sequence information to divergence dating now provide us with the tools and background to comprehend tarsier dispersal. Here, we describe effects of plate-tectonic movements, Pleistocene sea level changes, and hybridization on the…

Genome-wide analysis of Italian sheep diversity reveals a strong geographic pattern and cryptic relationships between breeds

2014

Summary Italy counts several sheep breeds, arisen over centuries as a consequence of ancient and recent genetic and demographic events. To finely reconstruct genetic structure and relationships between Italian sheep, 496 subjects from 19 breeds were typed at 50K single nucleotide polymorphism loci. A subset of foreign breeds from the Sheep HapMap dataset was also included in the analyses. Genetic distances (as visualized either in a network or in a multidimensional scaling analysis of identical by state distances) closely reflected geographic proximity between breeds, with a clear north–south gradient, likely because of high levels of past gene flow and admixture all along the peninsula. Sa…

(p,2)-equations resonant at any variational eigenvalue

2018

We consider nonlinear elliptic Dirichlet problems driven by the sum of a p-Laplacian and a Laplacian (a (p,2) -equation). The reaction term at ±∞ is resonant with respect to any variational eigenvalue of the p-Laplacian. We prove two multiplicity theorems for such equations.

An Optoelectronic System for Measuring the Range of Motion in Healthy Volunteers: A Cross-Sectional Study.

2019

Background and Objectives: Within the clinical evaluation of multiple pathologies of the lower limb, the measurement of range of motion (ROM) of its joints is fundamental. To this end, there are various tools, from the goniometer as a reference to more recent devices such as inclinometry-based applications, photo capture applications, or motion capture systems. This study aimed to assess the validity, intra-rater, and inter-rater reliability of the VeloFlex system (VS), which is a new camera-based tool designed for tracking joint trajectories and measuring joint ROM. Materials and Methods: Thirty-five healthy volunteers (16 females

Eight new mutations and the expanding phenotype variability in muscular dystrophy caused by ANO5.

2012

Objective: Description of 8 new ANO5 mutations and significant expansion of the clinical phenotype spectrum associated with previously known and unknown mutations to improve diagnostic accuracy. Methods: DNA samples of 101 patients in 95 kindreds at our quaternary referral center in Finland, who had undetermined limb-girdle muscular dystrophy (LGMD), calf distal myopathy, or creatine kinase (CK) elevations of more than 2,000 IU/L, were selected for ANO5 genetic evaluation, and the clinical findings of patients with mutations were retrospectively analyzed. Results: A total of 25 patients with muscular dystrophy caused by 11 different recessive mutations in the ANO5 gene were identified. The …
