With the advent of social media, the volume of photographs uploaded on the internet has increased exponentially. The task of efficiently recognizing and retrieving human facial images is inevitable and essential at this time. In this work, a feature selection approach for recognizing and retrieving human face images using hybrid cheetah optimization algorithm is proposed. The deep feature extraction from the images is done using deep convolutional neural networks. Hybrid cheetah optimization algorithm, an improvised version of cheetah optimization algorithm fused with genetic algorithm is used, to choose optimum features from the extracted deep features. The chosen features are used for finding the best-matching images from the image database. The image matching is performed by approximate nearest neighbor search for the query image over the image database and similar images are retrieved. By constructing a k-NN graph for the images, the efficiency of image retrieval is enhanced. The proposed system performance is evaluated against benchmark datasets such as LFW, MultiePie, ColorFERET, DigiFace-1M and CelebA. The evaluation results show that the proposed methodology is superior to various existing methodologies.

Fault diagnosis techniques of electrical motors can prevent unplanned downtime and loss of money, production, and health. Various parts of the induction motor can be diagnosed: rotor, stator, rolling bearings, fan, insulation damage, and shaft. Acoustic analysis is non-invasive. Acoustic sensors are low-cost. Changes in the acoustic signal are often observed for faults in induction motors. In this paper, the authors present a fault diagnosis technique for three-phase induction motors (TPIM) using acoustic analysis. The authors analyzed acoustic signals for three conditions of the TPIM: healthy TPIM, TPIM with two broken bars, and TPIM with a faulty ring of the squirrel cage. Acoustic analysis was performed using fast Fourier transform (FFT), a new feature extraction method called MoD-7 (maxima of differences between the conditions), and deep neural networks: GoogLeNet, and ResNet-50. The results of the analysis of acoustic signals were equal to 100% for the three analyzed conditions. The proposed technique is excellent for acoustic signals. The described technique can be used for electric motor fault diagnosis applications.

Microstructure, mechanical, and corrosion properties of as-cast pure zinc and its binary and ternary alloys with magnesium (Mg), and copper (Cu) additions were investigated. Analysis of microstructure conducted by scanning electron microscopy revealed that alloying additives contributed to decreasing average grain size compared to pure zinc. Corrosion rate was calculated based on immersion and potentiodynamic tests and its value was lower for materials with Cu content. Moreover, it was shown that the intermetallic phase, formed as a result of Mg addition, constitutes a specific place for corrosion. It was observed that a different type of strengthening was obtained depending on the additive used. The presence of the second phase with Mg improved the tensile strength of the Zn-based materials, while Cu dissolved in the solution had a positive effect on their elongation.

The relationship between self- and informant reports of personality using psychometric instruments is constantly the focus of attention for researchers in the field of clinical assessment in psychology. The research shows weak agreement between clinicians and patients’ assessments of personality disorders (PDs). The current study aimed at the convergence of measurement of PDs using the Shedler-Westen Assessment Procedure (SWAP-200), the self-report Character Styles Questionnaire-R (CSQ-R) and Borderline Personality Inventory (BPI). Paper-pencil questionnaires were administered to 102 inpatients (88.2% female, aged 18-64, M = 38.4) in a voivodeship hospital and outpatient health care centre. The SWAP-200 allowed us to gather expert (clinician) personality ratings basing on the intensive contact with patients. Results show that only a few SWAP-200 PD scales showed low positive correlations with corresponding self-reported PD scales from the CSQ-R. With the canonical correlation analysis, we identified two functions (borderline and internalising) that described similarities between the SWAP-200 and CSQ-R. SWAP-200 Obsessive-Compulsive PD correlated negatively with BPI scales. Consistent with previous studies, the self-report and the clinical assessment were only marginally convergent. Furthermore, OCPD stands out from other disorders in that it correlates positively with health indicators and negatively with some of the other personality disorders. The highest agreement was observed in the description of Borderline PD.

In the context of the socio-political instability that exists in Ukraine, the problem of stress resistance among psychological service professionals has emerged. The aim of the research is to analyse the professional activity of psychologists in Ukraine at the present stage under the influence of stress factors. The following methods were used to study the nature of stress and its impact on the personality of a psychologist: analytical and synthesis methods, statistical, comparative, survey and interpretive methods. The research results theoretically reveal the peculiarities of the concept of stress, the stages of stress development, and identify the main stressors of professional activity. An empirical study of the stress resistance of psychologists was conducted. The influence of stress on the quality of psychological care was determined. Professional qualities in the psychologist's personality structure were identified, the phenomenon of professional exhaustion, the role of countertransference in counselling were studied, the importance of the code of ethics for psychologists and its violation in the course of practice were revealed. The importance of interventions and supervision as a means of psychological support for the professional development of psychologists was investigated, and statistical indicators of the level of stress were analysed. The practical significance of the research is determined by the current coverage of the problem of the impact of stress on the professional activity of a psychologist and in the creation of effective ways of emotional self-preservation and development of stress resistance, which provide the search for their resources for self-healing and effective work.

Understanding and measuring mental well-being among adolescents has recently become a priority. The validity and reliability study of the 7-item short version of the Warwick Edinburgh Mental Well-Being Scale (SWEMWBS) has not been examined in Turkish adolescents. Therefore, this study aims to adapt the 7-item Warwick Edinburgh Mental Well-Being Scale to Turkish and examine the relationships between loneliness, emotional flexibility, resilience, and mental well-being. The data were collected by convenience sampling method from 820 adolescents aged 14-18 from 73 city of Turkey. During the adaptation process of SWEMWBS, confirmatory factor analysis, concurrent validity, and reliability analysis were performed. The findings confirmed the one dimensionality of the 7-item scale on the Turkish adolescent sample. In addition, a significant positive relationship was found between mental well-being and emotional flexibility and resilience. However, there was a significant negative correlation between mental well-being and loneliness. The results showed that the Turkish version of SWEMWBS had strong psychometric properties in adolescents.

The aim of this study was to investigate the level of posttraumatic growth of cancer patients post-treatment in the context of selected sociodemographic characteristics, clinical markers, and psychological variables (positive and negative emotions, anxiety and depressive symptoms, gratitude, forgiveness, hope, importance of the spiritual aspect of life and the practice of religious faith). The study sample consisted of 110 patients post-treatment aged 22-79 years and with an average time since the completion of the last treatment ranging from 5 to 396 months. The Posttraumatic Growth Inventory, the Positive and Negative Affect Schedule, screening methods to measure anxiety (General Anxiety Dis- order-7) and depression (Patient Health Questionnaire-9), and questionnaires to measure dispositional gratitude (Gratitude Questionnaire GQ-6), dispositional hope (Adult Dispositional Hope Scale), and forgiveness (Heartland Forgiveness Scale) were used to measure the psychological variables. There were no differences in the level of posttraumatic growth in terms of sociodemographic characteristics and clinical markers. Partner status, employment status, presence of recurrence, and comorbidities did not differentiate its level either. The rate of posttraumatic growth was related to the experience of positive emotions, gratitude, the importance of the spiritual aspect of life, and the practice of religious faith. In the regression model that explained 21.90% of the variance in posttraumatic growth, only the level of positive emotions was a significant predictor. The results of the present research point suggest that the level of posttraumatic growth is associated with several areas of emotional experience and cognitive adjustment of cancer patients post-treatment.

Vast research has sought to better understand the origins and development of rape myth beliefs given the problematic influence of such misconceptions throughout global societies and criminal justice pathways. The current research aims to build on this body of literature by examining the contribution that psychopathic personality traits (affective responsiveness, cognitive responsiveness, interpersonal manipulation, egocentricity) and emotional intelligence may have upon rape myth beliefs. Furthermore, this study will investigate the extent to which sociodemographic characteristics (age, gender, ethnicity, education), and prior experience of sexual victimisation, contribute to variance in rape myth acceptance scores. In total 251 participants (M Age = 31.66) completed an online, self-report questionnaire which included contemporary measures of psychopathy and rape myth acceptance, never previously tested in combination. Results of a hierarchical multiple regression analysis indicate that egocentricity, age, and gender were significantly associated with rape myth beliefs. Emotional intelligence, as well as affective and interpersonal traits of psychopathy, were not directly related with rape mythology. Findings are interpreted alongside previous research, where we suggest there is an urgent need for larger, nationally representative samples, systematically recruited from the general population to help clarify uncertainty in existing literature emerging from small-scale opportunistic datasets.

Self-esteem and emotional reactivity may be important personality determinants of human functioning in situations of social exposure. In this study, we compared the levels of these personality variables in a group of professional theater actors and a group of professional illusionists with a control group of participants who were neither actors nor illusionists and had no artistic education. We also examined the correlations between emotional reactivity and self-esteem in the three groups. For emotional reactivity, we found (1) very strong evidence that the level is less for magicians than for controls, (2) substantial evidence that the level is less for magicians than for actors, (3) anecdotal evidence that the level is less for actors than for controls, and (4) decisive evidence that the average score is less for males than for females. For self-esteem, we found (1) anecdotal evidence that the level is higher for magicians than for controls, (2) substantial evidence that there is no difference between actors and magicians, (3) anecdotal evidence against a difference between actors and controls, and (4) anecdotal evidence against a difference between males and females. Based on the entire sample we found a moderate correlation between self-esteem and emotional reactivity (r = -.30, p < 0.001). Our results are compatible with the notion that emotional reactivity – as part of the temperament concept – is a factor influencing the choice of an artistic profession.

This paper explores the psychometric properties of the Polish adaptation of the MBI-SS questionnaire, which measures academic burnout in students. The factorial structure of the tool was examined, and its validity was evaluated using a sample from Polish state universities (N=935).
Findings suggest that the MBI-SS possesses strong psychometric parameters. Data supports the tool's 3-factor structure and internal consistency. However, there are reservations regarding one item (MBI_6). Consequently, the 15- item version of the MBI-SS is recommended as a suitable tool for assessing burnout in Polish students.
