The nature of child-adult interaction : from turn-taking to understanding pointing and use of pointing gestures

Analyses of interactions between an adult and a one-year-old child are often connected with studying early communicative competences, e.g. the child’s participation in turn-taking sequences, in joint attention, and use of pointing gestures. Infants’ communicative behaviors were studied using a structured observational measure – the Early Social Communication Scales (Mundy et al., 2003) in a study of 358 12-month-old children. An exploratory factor analysis revealed: (i) a distinction between the categories of initiation and response among the behaviors displayed, (ii) simple and complex behavior categories occurring; (iii) the presence within one factor of behaviors fulfilling various functions (e.g. requesting and sharing interest). An analysis of the results showed that communicative competences can be classified according to their level and ignoring their function, and made it possible to suggest modifications to the way in which behaviors are coded on the ESCS and to complement the procedure of studying early communicative competences

Change and consistency of self-esteem in early and middle adolescence in the context of school transition

Self-esteem is continuous and has stable characteristics, but it may also change, e.g., during transitions from one educational level to the next. In a prospective cross-sectional study over a year and a half, 250 Polish early adolescents (N = 109, 54 girls; mean age at T1 = 12.68 years, SD = 0.49) and middle adolescents (N = 141, 107 girls; mean age at T1 = 15.80, SD = 0.44) were tested three times using Harter's Self-Perception Profile for Adolescents, assessing both global self-esteem and self-evaluation in eight domains. The change and consistency of self-esteem were analyzed, at both group and individual levels. At the group level, the following results were found: (1) continuity of self-esteem in five domains (scholastic competence, athletic competence, physical appearance, close friendship, and romantic appeal) and in global self-esteem and discontinuity in only three domains (social acceptance, job competence, and behavioral conduct); (2) significant inter-individual variation in the change not explained by age; and (3) higher self-esteem (in five domains) in early adolescents. At the individual level, the stability in most domains was weak, but was restored over the second year at the new school. The complexity of the developmental change and consistency in self-esteem in adolescence was highlighted, emphasizing the need for analyzing both group and individual change

Emotional and attentional predictors of self-regulation in early childhood

The development of self-regulation in early childhood is related to development of emotional regulation and attention, in particular executive attention (Feldman, 2009; Posner & Rothbart, 1998). As the ability to self-regulate is crucial in life (Casey et al., 2011), it is important to reveal early predictors of self-regulation. The aim of the paper is to present the results of longitudinal studies on the relationships between the functioning of attention, regulation of emotion and later self-regulatory abilities. 310 children were assessed at three time points. At 12 months of age emotional regulation in situation of frustration and attention regulation were assessed. At 18 and 24 months behavioral-emotional regulation in the Snack Delay Task was measured. Additionally parents assessed executive attention using The Early Childhood Behavior Questionnaire when children were 26 months old. Structural equation modelling revealed two different paths to development of self-regulatory abilities at 18 months: emotional (reactive system) and emotionalattentional and only one emotional-attentional path at 24 months. The early ability to focus attention and later executive attention functioning revealed to be important predictors of self-regulatory abilities both at 18 and 24 months of age

Odkrywanie kompetencji komunikacyjnych niemowląt. Skala Wczesnej Komunikacji Społecznej jako przykład narzędzia pomiarowego

The aim of the present analysis is to describe the developmental trajectory of the infant and toddler communicative competencies. Turn-taking, gaze-following, joint attention and pointing gestures are the most important expressions of these competencies that could be measured by the Early Social Communication Scale (ESCS Mundy et al., 2003). We present the results of a research conducted with 358 one-year old children and obtained through the Polish version of this scale (ESCS). The validity and reliability of the Polish version of ESCS proved to be satisfactory. The obtained results were analyzed emphasizing the role of early communicative competencies in the further social, linguistic and cognitive development of a child and indicating the domain of psychological practice where ESCS could be implemented.

The comparison between TP53 gene polymorphisms (c.[215G>C]) homozygotes and heterozygotes in Breast Cancer Patients: A clinicopathological analysis

Purpose: TP53 is a tumor suppressor gene which participates in regulation of cell cycle check points, DNA repair, and apoptosis. The aim of this study was to compare TP53 germ line gene polymorphisms (c.[215G>C]) wild – type homozygotes GG with heterozygotes GC according to clinicopathological factors.Methods: We reviewed the medical records of 87 (22% TP53 gene homozygotes and 78% heterozygotes) breast cancer patients who were diagnosed and treated in COI in Gliwice. Polymorphism profile was assessed by RFLP-PCR technique.Results: The presence of lobular invasive carcinoma was observed insignificantly more often in homozygotes, especially in the group of patients at the age below 50 years (29% vs. 4%, p = 0.095). Patients being TP53 gene heterozygotes had larger tumor size (T > 2) than homozygotes (16% vs. 5%, p = 0.450). There was observed a tendency to the presence of lymph node metastases (53% vs. 34%, p = 0.182) and higher Ki67 (> 20%) (69% vs. 46%, p = 0.209) in TP53 gene homozygotes. HER2 overexpression was associated with TP53 heterozygotes, especially in the group of patients at the age above 50 years (33% vs. 8%, p = 0.144). A negative receptor status was reported more frequently in homozygotes (43% vs.21%, p = 0.340) in patients with age below 50 years. Similarly higher histological grade G3 was detected more often in homozygotes in patients at the age below 50 years (80% vs. 33%, p = 0.130).Conclusion: TP53 gene homozygotes and heterozygotes differ from each other in respect of clinicopathological factors such as: histological type, lymph node metastases, higher Ki67 (> 20%), histological grade G3, ER/PR status, tumor size (T > 2), HER2 overexpression, cancer in family history and diabetes. Patient’s age was associated with the pathological characteristics of tumor

Analysis of the European Grouping of Territorial Cooperation with reference to the chosen examples.

Europejskie Ugrupowanie Współpracy Terytorialnej jest unijnym instrumentem kooperacji. Powstało stosunkowo niedawno i wciąż napotyka na różne problemy w swojej działalności. Celem mojej pracy jest przedstawienie EUWT jako narzędzia służącego pogłębianiu integracji europejskiej dzięki podejmowaniu "ponadgranicznych" inicjatyw. Praca została podzielona na trzy rozdziały, które po kolei omawiają najważniejsze aspekty tego zagadnienia. W pierwszej części przedstawiona została współpraca terytorialna w Europie, jej rozwój i charakterystyka. Nacisk został położony na działalność Unii Europejskiej w tym zakresie. Drugi rozdział w całości poświęcony jest Europejskiemu Ugrupowaniu Współpracy Terytorialnej - jego strukturze, funkcjonowaniu oraz kluczowym celom i zadaniom, które w dużej mierze opierają się na wykonywaniu projektów dotyczących jednego z bieżących celów polityki spójności, tj. Europejskiej Współpracy Terytorialnej. Trzecia część natomiast skupia się na bardziej praktycznej stronie omawianego ugrupowania i opisuje pierwszy tego typu instrument w Polsce- "TRITIĘ" z o. o., która ma szansę rozwinąć swoją działalność w nowym okresie programowania. Zaprezentowane zostało również pierwsze EUWT w Europie, mianowicie Eurometropolia, która z roku na rok rozwija swoją strukturę, przez co stała się wzorem dla wszystkich podmiotów wyrażających chęć zawiązania tego typu ugrupowania.The European Grouping of Territorial Cooperation is a relatively new EU tool facilitating the cross-border cooperation. The aim of that paper is to present the EGTC as an instrument which serves the deepening of the European integration by taking a various above borders initiatives. This paper is divided into three parts. First of them presents the territorial cooperation in Europe, its development and depiction. The emphasis on the EU activeness in that field is placed, especially within the cohesion policy. Second chapter is entirely derived to the introduction of the EGTC. Its structure, functioning are pointed, as well as its goals and tasks. The crucial characteristics of that tool is the implementation of the European Territorial Cooperation projects’ which is the main current objective of the above-mentioned cohesion policy. The last part focuses on the more practical aspect, namely the description of the first EGTC with the participation of the Polish entities - “TRITIA” Ltd. It has a chance to expand its functioning in the new programming period 2014-2020. Furthermore, the oldest grouping in Europe - the Eurometropolis which has been established in 2008 is also discussed. It is still undertaking the different steps towards improvement of its structure. Moreover, it is an excellent example for other partners willing to constitute such an instrument

Electrochemical Evaluation of the Compact and Nanotubular Oxide Layer Destruction under Ex Vivo Ti6Al4V ELI Transpedicular Screw Implantation

Nano-engineered implants are a promising orthopedic implant modification enhancing bioactivity and integration. Despite the lack of destruction of an oxide layer confirmed in ex vivo and in vivo implantation, the testing of a microrupture of an anodic layer initiating immune-inflammatory reaction is still underexplored. The aim of this work was to form the compact and nanotubular oxide layer on the Ti6Al4V ELI transpedicular screws and electrochemical detection of layer microrupture after implantation ex vivo by the Magerl technique using scanning electron microscopy and highly sensitive electrochemical methods. For the first time, the obtained results showed the ability to form the homogenous nanotubular layer on an Ti6Al4V ELI screw, both in α and β-phases, with favorable morphology, i.e., 35 ÷ 50 ± 5 nm diameter, 1500 ± 100 nm height. In contrast to previous studies, microrupture and degradation of both form layers were observed using ultrasensitive electrochemical methods. Mechanical stability and corrosion protection of nanotubular layer were significantly better when compared to compact oxide layer and bare Ti6Al4V ELI

Understanding technical cleanliness: importance, assessment, maintenance

Development of the automotive industry, including so-called dowsizing and rightsizing, entails the need to ensure, and hence to verify, the stringent cleanliness levels of an increasing number of car components. The assurance of proper cleanliness level requires knowledge of the entire production process and precise information on the contaminants that will allow to identify their sources. Obtaining reliable cleanliness information requires establishing of many different factors, i. a. selection of proper contamination extraction and collection technique, proper parameters of extraction, validation of extraction procedure, methods of particles analysis. Analytical techniques which are implemented include gravimetric, optical microscopy and advanced techniques like scanning electron microscopy. This work present’s actual state of knowledge regarding technical cleanliness analysis of components. Important aspects of QA&QC in technical cleanliness assessment are also discussed
