Opis:
Sociolinguistic competence is not often examined in nonnative English acquisition. This is particularly true for features where the variants are neither stylistically nor socially constrained, but rather are acceptable in all circumstances. Learning to use a language fully, however, implies being able to deal with this type of ‘difficulty,’ and understanding what type of variable features nonnative speakers acquire with ease and which ones they do not may help us better understand more general processes of second language acquisition. By comparing the rates of complementizer deletion of nonnative to native speakers and examining their distributions across various internal and external factors, this paper addresses these issues and offers an example of acquisition of what is, in some ways, an invisible variant. Furthermore, by focusing on a Swiss student association, the paper is also able to compare the patterns of French, German and Italian native speakers, to examine to what extent they differ in English.

 Praca rozszerza klasyczny model Barabasiego-Alberty o możliwość usuwania krawędzi. Pokazano, że wykładnik w prawie potęgowym rozkładu stopni wierzchołków zależy od liczby krawędzi dodawanych w każdym kroku procesu budowy grafu.
We extend the classical Barabási-Albert preferential attachment procedure by allowing edge deletion. We prove that unlike in the original model, power-law exponents of degree distribution of scale-free graphs with edge deletion depend on the number of attached edges in one step of the growing process.

Opis:
Cre recombinase from bacteriophage P1 is widely used in both in vitro and in vivo DNA manipulations. Based on a structural and functional analysis, three deleted cre mutants were constructed and expressed in Escherichia coli. Mutated recombinases were purified and their recombination activities were determined in vitro. Our results revealed that the mutant with amino-terminal deletion retains the recombination activity as high as wild type Cre; however, the carboxy-terminal deletion and the middle region deletion both lead to a complete loss of the recombinase function.

Opis:
Insertion and deletion are operations that occur commonly in DNA processing and RNA editing. Since biological macromolecules can be viewed as symbols, gene sequences can be represented as strings and structures can be interpreted as languages. This suggests that the bio-molecular structures that occur at different levels can be theoretically studied by formal languages. In the literature, there is no unique grammar formalism that captures various bio-molecular structures. To overcome this deficiency, in this paper, we introduce a simple grammar model called the matrix insertion–deletion system, and using it we model several bio-molecular structures that occur at the intramolecular, intermolecular and RNA secondary levels.

Opis:
Twenty-three patients with a putative diagnosis of Prader-Willi syndrome (PWS) were reassessed clinically and then examined by cytogenetic and molecular techniques. Nineteen patients fulfilled the diagnostic criteria for PWS and the remaining four were judged to have atypical PWS. Definite molecular defects were detected in all clinically typical PWS patients but one. A deletion of part of chromosome 15q could be identified molecularly in 14 patients (74%) and maternal disomy for chromosome 15 in four (21%). In all, except one, PWS patients with molecularly detected deletions, the deletion was also identified by cytogenetic studies. Cytogenetic deletions were suspected in two of the atypical PWS patients. However, based on the results of scoring the diagnostic criteria for PWS and on the PW71B methylation test, we were able to rule out PWS in all of our atypical patients. Our study confirms observations that both clinical and cytogenetic investigations can provide misdiagnoses of PWS in some patients, and the first, simple and fast investigation, which can confirm the PWS in most, if not all PWS patients, is molecular analysis by the methylation test.

If we want to retain the labeling analysis, alternatives to stranding must come forward, some of which I discuss here.

Opis:
The 5p deletion syndrome (5p-, Cri-du-chat syndrome, CdCS) is a genetic disorder which results from a partial deletion of the short arm of chromosome 5. It was first described by Lejeune et al. in 1963. The incidence ranges from 1:15 000 to 1:50 000 live births. The 5p- is usually diagnosed in the first days of life because of the characteristic monotonous high pitched cat-like cry and relatively constant dysmorphic features. Other symptoms often present in the neonatal period include low birth weight, muscle hypotonia, asphyxia and feeding difficulties due to impaired suction and swallowing, which may all lead to failure to thrive. Organ malformations, with various larynx abnormalities, although not very frequent, can also be present. Symptoms that are prevalent in later life include severe motor delay and intellectual disability with significant speech impairment, as well as behavioral problems. The case report presents a female infant in her 5th month of life in whom, despite the typical symptoms of 5p-, stridor and episodes of choking were the main problems. Laryngotracheal endoscopy revealed the type I laryngeal cleft. Genetic analysis confirmed the diagnose of 5p- syndrome. The presented case shows that it is critically important to perform a further investigation and refer a child with laryngological problems coexisting with dysmorphic features to a clinical geneticist.

Opis:
Change of the verb polarity or predicate deleted? Some French verbs, such as sortir, s’enfuir, s’éloigner, can be built with a preposition of polarity different from that of the verb: sortir dans, s’enfuir dans, s’éloigner vers. It is possible to consider these structures as the witness of deletion of a second verbal predicate: X sort (de la maison et entre) dans la rue, X s’éloigne (d’un endroit et s’approche) vers Y. We can see the same deletion in case of pluripolar verbs, which can be constructed with two prepositions (eg tomber).

Opis:
The problem of opacity presents a challenge for generative phonology. This paper examines the process of Nasal Assimilation in Polish rendered opaque by the process of Vowel Deletion in Optimality Theory (Prince & Smolensky, 1993), which currently is a dominating model for phonological analysis. The opaque interaction of the two processes exposes the inadequacy of standard Optimality Theory arising from the fact that standard OT is a non-derivational theory. It is argued that only by introducing intermediate levels can Optimality Theory deal with complex cases of opaque interactions.

Opis:
Background. Deletion syndrome 22q11.2 is a frequently occurring genetic disorder effecting not only malfunctions of the structure and function of many organs and systems, but also a number of psycho-social problems in patients of all ages. Objectives. The aim of the study was the evaluation of psycho-social problems experienced by people with confirmed 22q11DS observed by their parents/caregivers. Material and methods. A group of 32 parents’/caregivers’ children with 22q11DS diagnosis (confirmed by FISH or MLPA analysis) were examined. The age of patients at the moment of examination was from 3 months to 23 years. To identify the most frequent problems a questionnaire survey was used with the use of the authors’ questionnaire. Results. On the basis of the acquired data analysis it was stated that the most frequent problems in children reported by the questioned parents/caregivers were problems with speech development, problems with focusing attention, problem in relations with peers, and school difficulties. The questioned parents also emphasized excessive anxiety of the children and frequent behavior disorders. Moreover, many parents are concerned with their children’s adult lives, and emphasize the necessity of professional support (including psychological) in different stages of the sick child’s upbringing. Conclusions. Patients with 22q11DS experience many psychological and social problems and require, with their families, psychological support in different stages of life. The child’s condition, in many parents’ opinion, is a factor significantly influencing functioning in life and determining the occurrence of problems in the future. The task of primary care physicians is not only to identify patients suspected of 22q11DS and to lead them to genetic diagnostics, but also to provide support to the patients and their families in different stages of life in cooperation with many other specialists.
