Isolated PdO sites on SiO2-supported NiO nanoparticles as active sites for allylic alcohol selective oxidation

Silica-supported NiO nanoparticles as hosts for isolated PdO catalytic sites. Isolate PdO is confirmed as the species responsible for the chemoselective oxidation of cinnamyl alcohol to cinnamaldehyde by operando X-ray absorption spectroscop

General and specific individual post-traumatic stress disorder-related mechanisms among paramedics

Background Due to the nature of their work, paramedics face an increased risk of developing a post-traumatic stress disorder. The main goal of this research project was to point out specific correlates of post-traumatic stress. The authors decided to approach that issue from the perspective of emotional-cognitive deficits and resources, such as alexithymia, rumination and coping with stress. Material and Methods The authors conducted 3 independent research projects in the first half of the year 2017 in the Wielkopolskie voivodship, that included paramedics. In each one of them, they estimated post-traumatic stress disorder (PTSD) symptoms using The Impact of Event Scale-Revised (IES-R). Additionally, in the first study the authors used alexthymia scale, Polish verion of Toronto Alexithymia Scale-20 (TAS-20), in the second – rumination questionnaire, in the third – coping with stress measured with Inventory for Measuring Coping with Stress Mini-COPE . Results The analyses demonstrate a relationship between PTSD symptoms and both alexithymia and rumination. There was not any significant relationship between coping strategies and PTSD. The mediation analysis results prove the role of intrusion as a mediator in a relationship between hyperarousal and avoidance. Individuals with PTSD demonstrate high avoidance for situations similar to the original traumatic event because high hyperarousal increases the risk of intrusion. Conclusions More than a half of paramedics demonstrated post-traumatic stress symptoms, which most likely is a prognosis factor for future development of PTSD among them. The emotional-cognitive deficits correlated with traumatic stress symptoms. Resources such as coping strategies were not sufficient enough mechanisms for coping with traumatic stress. Post-traumatic stress disorder may be seen as a dynamic sequence. The nature of paramedics work entails the risk for experiencing complex and/or secondary trauma, which represent the phenomena that should be further examined. Med Pr. 2019;70(1):53–6

Physician – patient communication style and the patient’s motivation to comply with the health care recommendations

An increasing number of researchers indicate that communications between doctors and patients significantly affect the process of treatment. The aim of the present study was to investigate the effects of the type of physicians’ communication style on the patient’s motivation to compliance with the medical recommendations following the end of hospitalization. Thirty hospitalized patients took part in the study. They were asked to fill out questionnaires measuring the following groups of variables: doctor – patient communication style, level of positive and negative affect experienced during hospitalization, level of confidence in physicians, the assessment of medical services quality, and level of motivation to compliance with doctors’ recommendations after leaving hospital. Data were analyzed by means of correlation coefficient and regression analysis. The obtained results suggest that the level motivation to compliance with doctors’ recommendations is correlated with two communication styles named as: (1) personal-nonmedical (r = 0,51; p < 0,01) and (2) personal-medical (r = 0,40; p < 0,05). Besides, the results indicated that the motivation to comply with the recommendations is importantly linked to factors such as: trusting doctors (r = 0,50; p < 0,01) and satisfaction with medical services (r = 0,45; p < 0,05). The regression analysis showed that the level of motivation to compliance with doctors’ recommendations after leaving hospital depends on personal-nonmedical style of communication ( = 0,51; t = 3,11; p < 0,01) in 25% (R2 = 0,26; F = 9,66; p < 0,01). The results suggest that patients’ motivation to follow the doctors’ recommendations is the highest when the physician communicates with them in the personal-nonmedical style. The research also demonstrated that physicians need to develop their communication skills, especially their nonmedical aspect

Security theory and practice: Security in public governance

Z wprowadzenia: "W literaturze przedmiotu dyskutowane są związki między bezpieczeństwem publicznym a bezpieczeństwem wewnętrznym. Rozpatrywane są różne warianty, w których: 1) bezpieczeństwo wewnętrzne i bezpieczeństwo publiczne są traktowane jako odrębne, równorzędne kategorie; 2) bezpieczeństwo publiczne stanowi jedną z subkategorii w ramach bezpieczeństwa wewnętrznego lub 3) wyodrębnia się bezpieczeństwo wewnętrzne jako jedną z kategorii bezpieczeństwa narodowego, bez wymieniania bezpieczeństwa publicznego jako odrębnej kategorii."(...
