Problemy w przebiegu pierwszej fazy rozwoju wg koncepcji Erika Eriksona u dziecka niewidomego

Joanna Gładyszewska-Cylulko, Problemy w przebiegu pierwszej fazy rozwoju wg koncepcji Erika Eriksona u dziecka niewidomego [Problems of the first stage of psychosocial development according to Erik Erikson in a blind child]. Interdyscyplinarne Konteksty Pedagogiki Specjalnej, nr 22, Poznań 2018. Pp. 139-166. Adam Mickiewicz University Press. ISSN 2300-391X. DOI: https://doi.org/10.14746/ikps.2018.22.08 Erik H. Erikson, the author of the theory of psychosocial development, claimed that during their life from birth to death, every human being experiences eight developmental crises. Every time, at each stage there are two polar opposites, two conflicting values. To overcome the crisis we must find an optimal balance between them. How we resolve the crises affects our integration and relations with others and ourselves. In the article the author concentrates on the first developmental stage, considered by many to be the most important one. Its two opposites are basic trust and basic mistrust, while the basic virtue is hope. Unfortunately, due to the lack of appropriate experiences, improper attitude of other people and various otherfactors, blind children already at this stage often fail to properly resolve the developmental crisis. In further part of the article the author discusses the causes of the problem and suggests how the disturbances at the first stage of development might be prevented.Joanna Gładyszewska-Cylulko, Problemy w przebiegu pierwszej fazy rozwoju wg koncepcji Erika Eriksona u dziecka niewidomego [Problems of the first stage of psychosocial development according to Erik Erikson in a blind child].

Personality factors of the emancipation of people with visual disabilities

The purpose of the study was to find out the relationship between personality factors and tendency to emancipation. The author focuses on the most important problems of personality of persons with visual disabilities. She wonders why do certain factors of personality encourage the process while others slow it down. The process of emancipation is complex and long-lasting but very significant not only from the perspective of people with visual disabilities, but also for all the people in a community that respect diversity.The purpose of the study was to find out the relationship between personality factors and tendency to emancipation.

DOI: https://doi.org/10.14746/ikps.2018.22.11 The blind and visually impaired are one of the groups prone to stigma. Stigma imposed by social environment may lead to self-stigma, that is expressing negative opinions about oneself as a result of the carried sigma. Self-stigma usually develops in three stages: first the stigmatised person realizes that they have been stereotyped, then they accept the stereotype and finally apply it to themselves. Thus, to develop selfstigma, the person has to be aware that they are perceived by the society in a stereotypical way (a blind person is usually perceived as passive, dependent and reliant on other people’s help), accept it and acknowledge themselves that this is their real image. Not every visually impaired person is will develop self-stigma.

Chemometric approach to characterization of the selected grape seed oils based on their fatty acids composition and FTIR spectroscopy

Addressing the issues arising from the production and trade of low-quality foods necessitates developing new quality control methods. Cooking oils, especially those produced from the grape seeds, are an example of food products that often suffer from questionable quality due to various adulterations and low-quality fruits used for their production. Among many methods allowing for fast and efficient food quality control, the combination of experimental and advanced mathematical approaches seems most reliable. In this work a method for grape seed oils compositional characterization based on the infrared (FTIR) spectroscopy and fatty acids profile is reported. Also, the relevant parameters of oils are characterized using a combination of standard techniques such as the Principal Component Analysis, k-Means, and Gaussian Mixture Model (GMM) fitting parameters. Two different approaches to perform unsupervised clustering using GMM were investigated. The first approach relies on the profile of fatty acids, while the second is FT-IR spectroscopy-based. The GMM fitting parameters in both approaches were compared. The results obtained from both approaches are consistent and complementary and provide the tools to address the characterization and clustering issues in grape seed oils.O

Spectroscopic studies of dual fluorescence in 2-(4-fluorophenylamino)-5-(2,4-dihydroxybenzeno)-1,3,4-thiadiazole : effect of molecular aggregation in a micellar system

The article presents the results of spectroscopic studies focused on a selected compound from the 1,3,4-thiadiazole group—2-(4-fluorophenylamino)-5-(2,4-dihydroxybenzeno)-1,3,4-thia-diazole (FABT)—in a micellar system formed by Triton X-100, a non-ionic detergent. Fluorescence measurements revealed the phenomenon of dual fluorescence whose emergence is related to the particular molecular organisation of the compound, which depends both on the concentration of the detergent and, most of all, the concentration of the compound itself. Dual fluorescence of FABT in a micellar system was observed for the compound dissolved in a methanol aqueous system, i.e., an environment wherein the dual fluorescence of the compound had never been reported before. Based on the interpretation of UV-Vis electronic absorption, resonance light scattering (RLS), emission and excitation fluorescence spectra, as well as measurements of dynamic light scattering (DLS) and Principal Component Analysis (PCA), we were able to relate the occurrence of this effect to the process of molecular aggregation taking place between FABT molecules in the micellar system in question. Results of fluorescence spectra measurements and time-correlated single photon counting (TCSPC) indicate that dual fluorescence occurs at detergent concentrations necessary to form micellar systems, which in turn facilitate the process of aggregation of FABT molecules. The correlation between the observed fluorescence effects and the previous measurements performed for analogues from this group suggests the possibility of charge transfer (CT) within the range of detergent concentrations wherein the aforementioned fluorescence effects are observed. It ought to be emphasised that this type of fluorescence effects are relatively easy to induce, which predisposes this groups of fluorophores as ideal fluorescence probes in the context of biological samples

ESIPT-related origin of dual fluorescence in the selected model 1,3,4-thiadiazole derivatives

In our previous work, we discussed the emergence of the dual fluorescence phenomenon in selected compounds from the group of 1,3,4-thiadiazoles. The results obtained in a number of experimental studies, supported by [TD]DFT calculations, clearly indicated that the phenomenon of dual fluorescence stemmed from an overlap of several factors, including the correct conformation of the analyzed molecule and, very significantly in this context, aggregation effects. Where those two conditions were met, we could observe the phenomenon of intermolecular charge transfer (CT) and the emergence of electronic states responsible for long wave emissions. However, in light of the new studies presented in this paper, we were able, for the first time, to provide a specific theory for the effect of dual fluorescence observed in the analyzed group of 1,3,4-thiadiazoles. We present the results of spectroscopic measurements conducted for two selected analogues from the 1,3,4-thiadiazole group, both in polar and non-polar solvents, which clearly evidence (as we have already suspected in the past, albeit have not shown in publications to date) the possibility of processes related to emission from the tautomer formed in the process of excited state intramolecular proton transfer, which is responsible for the long-wavelength emissions observed in the selected analogues. The presented results obtained with the use of UV-Vis, fluorescence (stationary and time-resolved), FTIR, and Raman spectroscopy, as well as from calculations of dipole moment changes between the ground and excited state with the use of two derivatives with different structures of the resorcylic system, corroborated our standing hypothesis. At the same time, they excluded the presence of ground state keto forms of the analyzed analogues unless necessitated by the structure of the molecule itself. In this case, aggregation factors enhance the observed effects related to the dual fluorescence of the analyzed compounds (by way of AIE—aggregated induced emissions)

Indoor Air Quality in the Bedroom of a Single-Family House—A Case Study

People spend nearly 1/3 of their lives in bedrooms. Moreover, the greatest part of this time is spent in lack of awareness, so it is important to maintain suitable conditions in these areas, including air quality. In non-ventilated bedrooms, people may have trouble falling asleep, may not be resting enough during sleep, and they can wake up tired. This affects their well-being and behavior throughout the next day. Indoor air quality measurements were carried out in a single-family home bedroom. The measurements were made in unsealed windows. In the bedroom under examination, where people stay only during the night and where the door is always open and air is constantly being renewed, the carbon dioxide concentration during the night exceeded the permissible standard—1000 ppm
