Annotation. The paper presents the results of statistical calculations of psychophysiological examinations of 80 military pilots and flight navigators with different levels of suitability for flight performance. The authors analyze the effects of the temporal factor (after the vacation leave) on the psychophysiological qualities of military pilots, other indices of individual typological and psychodynamic qualities which prove to be the indicator of the possibilities of man’s adaptation to the conditions of the task performance. With respect to investigating the above possibilities, we have determined the time period for carrying out their assessment with the aim of determining reasonably the level of the military pilot professional suitability. This makes it possible to timely prevent the negative changes in the state of health and professionally important qualities of pilots in order to support and rehabilitate their readiness for performing the tasks assigned. When carrying out the investigation we managed to take into account the external criteria of success rate in performing the professional duties of pilots: the efficiency of professional activities, the pilot’s qualification and total flight hours. The authors also reveal the difference in the correlation of psychophysiological functions in pilots suitable and unsuitable for performing their professional duties. The authors suggest the up-to-date methodical approaches to monitoring the psychophysiological qualities with the aim of the further development on this basis the criteria for the professional suitability of the pilot. Special solution rules of determining the level of suitability of military pilots for performing their professional duties are developed.

Annotation. The article is devoted to the study of the peculiarities of the transformation of professionally important psychophysiological qualities of military pilots who are practically healthy and patients with stage I hypertension. The article highlights the hidden factors that contribute to the performance of a military pilot. These factors make it possible to explain the peculiarities of the mechanisms of organization of working capacity in practically healthy and patients with hypertension and stage I military pilots. Special decision-making rules have been developed, which make it possible to state that even small changes in the state of health that occur during the development of stage I hypertension are appropriately reflected in the level of psychophysiological functions on the basis of which it is possible to distinguish with a probability of 77.5%. The degree of connection between the state of health of military pilots and the level of their psychophysiological characteristics was assessed. Recommendations for taking into account cognitive changes in pilots of patients with stage I hypertension have been developed. It is established that stage I hypertension affects the structure of correlations of psychophysiological functions of the body, which shows the difference in the mechanisms of regulation of these functions in the development of the disease. It is shown that even practically healthy military pilots have different levels of mental capacity and can show their psychophysiological qualities in different ways, especially in extreme conditions. In addition, it was found that hypertension makes about a third of the surveyed sick pilots more active, which, in turn, increases the physiological cost of professional activities, to reduce which requires periodic treatment and prevention and rehabilitation measures.

AbstractThis text is devoted to a discussion of current achievements in the psychology of creativity, as well as to the further development of the field. It is concerned with a criticism of former and current theses in the field of the psychology of creativity discussed by Glăveanu (2014). The arguments presented indicate that, despite Glăveanu’s (2014) proposition, the psychology of creativity is not in crisis. It is pointed out that the difference in views between supporters of the social psychology approach to creativity and psychology researchers oriented towards the study of creative potential on how to conduct creativity research, stems from a concentration on different levels of creativity, and not necessarily from an ineffective theory of creativity. As a consequence of these different perceptions of creativity at its particular levels, determining the prime standard of creative potential is not sufficient to understand the social conditioning of creative activity and the social assessment of creativity, and vice versa.

Annotation. The article is devoted to the study of the peculiarities of the transformation of professionally important psychophysiological qualities of military pilots, practically healthy and with stage I hypertension (80 people). Statistical analysis of the data was performed using the methods of variation statistics, nonparametric statistics – correlation (Spearman’s correlation coefficient), cluster analysis (k-means method) using the software package STATISTICA 13.3. It has been established that hypertension affects the structure of correlations of psychophysiological functions of the body, which indicates a difference in the mechanisms of regulation of these functions during the development of the disease. It is shown that even healthy military pilots have different levels of mental capacity and can show their psychophysiological qualities in different ways, especially in extreme conditions. In addition, it was found that in the presence of hypertension in the body of a third of pilots show compensatory reactions to increase the activation of body functions, which, in turn, increases the physiological cost of professional activity, to reduce which must periodically apply treatment and rehabilitation measures.

The main principle of vibration-based damage detection in structures is to interpret the changes in dynamic properties of the structure as indicators of damage. In this study, the mode shape damage index (MSDI) method was used to identify discrete damages in plate-like structures. This damage index is based on the difference between modified modal displacements in the undamaged and damaged state of the structure. In order to assess the advantages and limitations of the proposed algorithm, we performed experimental modal analysis on a reinforced concrete (RC) plate under 10 different damage cases. The MSDI values were calculated through considering single and/or multiple damage locations, different levels of damage, and boundary conditions. The experimental results confirmed that the MSDI method can be used to detect the existence of damage, identify single and/or multiple damage locations, and estimate damage severity in the case of single discrete damage.

Abstract Background Sanitizing the operating theatres (OT) is important to minimize risk of post-operative infections. Disinfection procedures between one operation and another is less aggressive than final cleaning procedures, at the end of the day. Aim was assessing the difference of contamination: i) between different levels of disinfection; ii) before and after the use of a UVC Device (UVC-D). Methods Between December 2019/February 2020 a cross sectional study was conducted in OT in a real clinical context. 94 Petri dishes (PD) were used in 3 OT. Three different sanitation levels (SL1-3) were compared pre- and post-use of UVC-D: i) No cleaning after surgery (SL1); ii) after in-between cleaning (SL2); iii) after terminal cleaning (SL3). UVC-D was employed for 6 minutes, 3 minutes per bed side. PD were incubated at 36 °C and colony forming unit (CFU) counted at 48h. Descriptive statistic, Wilcoxon and Mann-Whitney tests were performed to assess the contamination levels in total, pre/post use of UVC-D, and between different sanitation levels, respectively. Results In total we had a mean of 3.39 CFU/PD (C.I. 2.05 - 4.74) and a median of 1 CFU/PD (Min. 0 - Max. 39), after UVC-D use we had a mean of 2.20 CFU/PD (C.I. 0.69 - 5.09) and a median of 0 CFU/PD (Min. 0 - Max. 133). The UVC-D led to a significant reduction of CFU (p < 0.001). Without UVC-D we had a significant CFU drop (p < 0.05) between SL1 and SL3. Using UVC-D, we observed significant reductions of contamination (p < 0.05) between SL3 and SL1. Comparing SL1 (median 0) post UVC-D use vs SL2 pre UVC-D use (median 0.5), and SL2 post UVC-D use (median 0) vs SL3 pre UVC-D use (median 1) we had a significant reduction of contamination (p < 0.05). Conclusions UVC-D improved environmental contamination in any of the three sanitation levels. Furthermore, the use of UVC-D alone was better than in-between and terminal cleaning. Although these encouraging results, the cleaning procedures executed by dedicated staff has to be considered. Key messages UVC are efficient to decrease contamination in operating theatres regardless of sanitation levels. The additional use of UVC technology to standard cleaning procedures significantly improves sanitation levels.

Abstract The aim of this study was an attempt to verify whether Polish speakers of English insert a vowel in the word-final clusters containing a consonant and a syllabic /l/ or /n/ due to the L1–L2 transfer. L1 Polish speakers are mostly unaware of the existence of syllabic consonants; hence, they use the Polish phonotactics and articulate a vocalic sound before a final sonorant which is deprived of its syllabicity. This phenomenon was examined among L1 Polish speakers, 1-year students of English studies, and the recording sessions were repeated a year later. Since, over that time, they were instructed with regard to phonetics and phonology but also the overall practical language learning, the results demonstrated the occurrence of the phenomenon of vowel insertion on different levels of advanced command of English. If the vowels were inserted, their quality and length were monitored and analysed. With regard to the English system, pronouncing vowel /ə/ before a syllabic consonant is possible, yet not usual. That is why another aim of this study is to examine to what extent the vowels articulated by the subjects differ from the standard pronunciation of non-final /ə/. The quality differences between the vowels articulated in the words ending with /l/ and /n/ were examined as well as the potential influence from the difference between /l/ and /n/ on the occurrence of vowel reduction. Even though Polish phonotactics permit numerous consonantal combinations in all word positions, it proved to be challenging for L1 Polish speakers to pronounce word-final consonantal clusters containing both syllabic sonorants. This result carries practical implications for the teaching methodology of English phonetics.

Accelerated losses of biodiversity are a hallmark of the current era. Large declines of population size have been widely observed and currently 22,176 species are threatened by extinction. The time at which a threatened species began rapid population decline (RPD) and the rate of RPD provide important clues about the driving forces of population decline and anticipated extinction time. However, these parameters remain unknown for the vast majority of threatened species. Here we analyzed the genetic diversity data of nuclear and mitochondrial loci of 2,764 vertebrate species and found that the mean genetic diversity is lower in threatened species than in related nonthreatened species. Our coalescence-based modeling suggests that in many threatened species the RPD began ∼123 y ago (a 95% confidence interval of 20–260 y). This estimated date coincides with widespread industrialization and a profound change in global living ecosystems over the past two centuries. On average the population size declined by ∼25% every 10 y in a threatened species, and the population size was reduced to ∼5% of its ancestral size. Moreover, the ancestral size of threatened species was, on average, ∼22% smaller than that of nonthreatened species. Because the time period of RPD is short, the cumulative effect of RPD on genetic diversity is still not strong, so that the smaller ancestral size of threatened species may be the major cause of their reduced genetic diversity; RPD explains 24.1–37.5% of the difference in genetic diversity between threatened and nonthreatened species.

IntroductionQuaternary prevention, concept coined by the Belgian Marc Jamoulle, are the actions taken to avoid or mitigate the consequences of unnecessary or excessive intervention of the health system. The concept alludes to actions to avoid the over-diagnoses and over-treatment, trying to reduce the incidence of iatrogeny in patients, which is a serious public health problem and even more in mental health.MethodsSystematic review of bibliography.ObjectivesDo a systematic review of bibliography and through the results invite to the analytic and critic reflection of our professional activities and the current situation of mental health.ResultsThere is not enough studies about quaternary prevention in mental health.–Some studies found that about one-third of diseases of a hospital are iatrogenic, most of them for pharmacological causes.–There is iatrogeny at different levels of the attention of mental health: primary prevention, diagnosis and treatment.–Non-treatment indication avoids in multiple cases iatrogenesis and contributes to the correct distribution of the economic and care resources.ConclusionsSince one of the fundaments of medicine is “primun non nocere” that means “first do no harm” and one of principles of bioethics is “non-maleficence”, quaternary prevention should prevail over any other preventive or curative option.–We should define in a more realistic way the limits, benefits and damages of our interventions in order to not promote a passive and sick role.–Must be recognized the non-treatment intervention as a therapeutic and useful intervention, and one of the best tools of quaternary prevention.Disclosure of interestThe author has not supplied his/her declaration of competing interest.

The Kurdish Civil War between the military forces of the Kurdistan Democratic Party (KDP) and the Patriotic Union of Kurdistan (PUK) began in 1994. Despite frequently occurring peace talks throughout the conflict, negotiations failed to bring about a durable settlement until the United States brokered the Washington Peace Agreement in 1998. This research explores why the earlier negotiations were unsuccessful, and whether it was only the US mediation in 1998 which made the difference. Although the US mediation was clearly an important factor, by employing the contingency model this research argues that both contextual variables and process variables determined the success of negotiations in 1998. Furthermore, they can explain the failure of the previous 4 years of negotiations.
