Політичні стереотипи та стереотипізація мислення: роль та значення у системі іміджевих комунікацій

Всебічно розглянуто особливості стереотипізації мислення як важливого чинника у процесі сприйняття та аналізу особою або групою осіб суспільно-політичної дійсності. Досліджено природу, джерела та механізми формування політичних стереотипів та показано їх роль і значення у системі іміджевих комунікацій. Наголошено на необхід- ності аналізу існуючої системи стереотипів при створенні іміджу суб’єкта політики.There have been thoroughly examined peculiarities of stereotyping of thinking as an important factor in the process of perception and analysis of socio-political reality by a person or a group of people. There have been investigated the nature, sources and mechanism of political stereotypes formation and showed their role and meaning in the system if image communications. There has been put an emphasis on the necessity of analysis of the existing system of stereotypes while creating the image of a subject of policy

The focus of light - linear polarization breaks the rotational symmetry of the focal spot

We experimentally demonstrate for the first time that a linearly polarized beam is focussed to an asymmetric spot when using a high-numerical aperture focussing system. This asymmetry was predicted by Richards and Wolf [Proc.R.Soc.London A, 253, 358 (1959)] and can only be measured when a polarization insensitive sensor is placed in the focal region. We used a specially modified photodiode in a knife edge type set up to obtain highly resolved images of the total electric energy density distribution at the focus. The results are in good agreement with the predictions of a vectorial focussing theory.Comment: to be published in "Journal of Modern Optics

Relationship Satisfaction Among Mothers of Children With Congenital Heart Defects: A Prospective Case-Cohort Study

Objective To assess the level of partner relationship satisfaction among mothers of children with different severity of congenital heart defects (CHD) compared with mothers in the cohort. Methods Mothers of children with mild, moderate, or severe CHD (n = 182) and a cohort of mothers of children without CHD (n = 46,782) from the Norwegian Mother and Child Cohort Study were assessed at 5 time points from pregnancy to 36 months postpartum. A 5-item version of the Relationship Satisfaction scale was used, and relevant covariates were explored. Results The trajectories of relationship satisfaction among mothers of children with varying CHD severity did not differ from the trajectories in the cohort. All women in the cohort experienced decreasing relationship satisfaction from 18 months after delivery up to 36 months after delivery. Conclusions Having a child with CHD, regardless of severity, does not appear to exacerbate the decline in relationship satisfactio

Active zone proteins are dynamically associated with synaptic ribbons in rat pinealocytes

Synaptic ribbons (SRs) are prominent organelles that are abundant in the ribbon synapses of sensory neurons where they represent a specialization of the cytomatrix at the active zone (CAZ). SRs occur not only in neurons, but also in neuroendocrine pinealocytes where their function is still obscure. In this study, we report that pinealocyte SRs are associated with CAZ proteins such as Bassoon, Piccolo, CtBP1, Munc13–1, and the motorprotein KIF3A and, therefore, consist of a protein complex that resembles the ribbon complex of retinal and other sensory ribbon synapses. The pinealocyte ribbon complex is biochemically dynamic. Its protein composition changes in favor of Bassoon, Piccolo, and Munc13–1 at night and in favor of KIF3A during the day, whereas CtBP1 is equally present during the night and day. The diurnal dynamics of the ribbon complex persist under constant darkness and decrease after stimulus deprivation of the pineal gland by constant light. Our findings indicate that neuroendocrine pinealocytes possess a protein complex that resembles the CAZ of ribbon synapses in sensory organs and whose dynamics are under circadian regulation

Emotional reactivity in infants with congenital heart defects: findings from a large case-cohort study in Norway

AIM: Advances in medical treatment in recent years have led to dramatically improved survival rates of children with severe congenital heart defects (CHD). However, very little is known about the psychological consequences for these children, particularly during and after the early period of invasive treatment. In this study, we investigated the extent to which the severity of the CHD affects the child's emotional reactivity at 6 months of age. METHOD: We linked prospective data from the Norwegian Mother and Child Cohort Study, conducted by the Norwegian Institute of Public Health with a nationwide medical CHD registry and identified 212 infants with CHD in a cohort of 61 299 infants. Mothers reported on their child's emotional reactivity at age 6 months by means of a standardized questionnaire. RESULTS: Infants with severe to moderate CHD had 60% higher odds for severe emotional reactivity (cut-off at the 85 percentile) compared with healthy infants, after controlling for important maternal and child confounders. CONCLUSION: Our study is the first to show elevated emotional reactivity in children with moderate to severe CHD, suggesting a need for special parental attention to soothe their distress. Follow-up studies will show whether this emotional reactivity is transient or an early marker of continuing emotional or behavioural problems
