Basic Properties of Relative Entropic Normalized Determinant of Positive Operators in Hilbert Spaces
Full text linkHOW TO INFER MATHEMATICAL SEQUENTIAL MEDIATION RELATIONSHIPS FROM NETWORK ANALYSIS: 10.24250/jpe/1/2025/DR/GR/
No full textThis paper explores the statistical inference of mathematicalsequential mediation relationships through network analysis,utilizing JASP for network modeling and SPSS Process Macro(Model 6) for mediation analysis. Sequential mediation analysisis particularly useful when dealing with highly complextheoretical models or when no theoretical model exists, enablingexploratory or confirmatory studies of specific mediationrelationships. Network analysis serves as a complementary toolto identify potential pathways and interrelations within variablesbefore applying mediation models. The paper includes anapplied example within a study that uses an extended TechnologyAcceptance Model (TAM) to identify factors promoting TAMadoption among preschool teachers. The methodologicalimplications of combining sequential mediation and networkanalysis are discussed, offering significant contributions to thebehavioral sciences
FORMATIVE ASSESSMENT – AN OBJECTIVE IN UNIVERSITY EDUCATION: 10.24250/jpe/1/2025/MIF/
No full textThe quality of assessment in university education depends, toa considerable extent, on the professional training of teachers inthe creation of a system of practical-applicative strategies informative assessment, which is a valuable tool for adapting andadjusting the teaching-learning process. Recently, formativeassessment research has gained considerable momentum. In thecontext of post-modern education, assessment is expanding itsscope, moving beyond the end of the learning process andactively integrating into it. Thus, the student becomes an activeparticipant in the learning and assessment process, taking on therole of an actor in his or her own learning. Based on learning,formative assessment plays an essential role in universityeducation through authentic feedback between teachers andstudents. Formative assessment thus has two essential functions:on the one hand, it helps to correct the teaching process in orderto reduce the difficulties encountered by students and, on theother hand, it allows the teaching-learning process to beadjusted
FEEDBACK IN FORMATIVE ASSESSMENT: 10.24250/jpe/1/2025/AFR/MIF/
No full textIn modern didactics, assessment is perceived as a complex,continuous activity, designed to take place in distinct butinterconnected stages throughout the educational process.Formative assessment involves the constant monitoring ofoutcomes throughout the instructional process, thus ensuringprogressive and well-structured learning in small sequences. Animportant aspect of this process is the feedback that providesuseful information to students on their performance. In theresearch that I carried out in the undergraduate programPedagogy of Primary and Pre-school Education, a number of keyelements were investigated that refer to the aspects of feedbackin formative assessment. The mode of investigation used in theresearch was the survey, carried out using the questionnaire asan instrument. A number of novel elements of the presence offeedback in formative assessment emerged from the research
MANAGING PSYCHOSOMATIC DISORDERS IN STUDENTS. THE ROLE OF THE SOCIAL WORKER IN IDENTIFYING FAMILY RISK FACTORS: 10.24250/jpe/1/2025/AC/
No full textGanong, Coleman (2014) summarizes the evidence to answer the question: why use qualitative family research? Tthe authors mention only a few benefits of these studies, namely, exploring meanings, capturing relational processes. The study aims to highlight the importance of the complexity of the social worker's activity and the need to integrate psychological knowledge into professional practice, in order to improve the quality of social intervention. A case of psychosomatic disorder, selected through intentional qualitative sampling, very faithfully reflects a reality frequently encountered in school, namely that the school environment takes on the problems of the family and societal system through its students. The exploration of family relational processes, possible by integrating elements of family and child psychology, once again emphasizes the impact of the family environment on the child. The importance of providing the presence of social workers in schools, challenged to respond as documented, attentive and professional as possible to increasingly complex realities, is discussed
ARTIFICIAL INTELLIGENCE AND SOCIAL WORK: PREPARING STUDENTS FOR A HUMAN-CENTERED PROFESSION IN THE DIGITAL AGE: 10.24250/jpe/si/2025/GSM/TD/
No full textThe paper explores the perception of first-year studentsfrom the Department of Social Work regarding the use ofartificial intelligence in the educational process as well asin the social work profession. A descriptive research designwas employed, using a semi-structured interview guide,and 16 individual interviews were conducted. The practicalimplications focus on the ethical and responsible use ofartificial intelligence, while simultaneously fosteringcritical thinking and qualitative learning. Furthermore, theprofessions of teacher and social worker are discussed inthe context of the emergence of artificial intelligence in thedigital era
ASSESSMENT OF SURFACE WATER QUALITY IN JIU VALLEY MINING AREA
Full text linkThe main objective of the present study was to perform a general screening of surface water quality in Jiu Valley mining rea. Surface waters were collected from West Jiu river and some of its tributaries (Caprisoara creek; Baleia creek; Barbateni creek; Vacii Valley creek; Tusu creek; Bulzu creek) to analyze several general physico-chemical and some specific chemical quality parameters. The general physico-chemical parameters: pH, redox potential (ORP), salinity, total dissolved solids (TDS), electrical conductivity (EC) and dissolved ions were analyzed.The analyzed water samples had a neutral pH, with a relatively low content of dissolved salts, except for Caprisoara creek. Based on their dissolved ions content, most of the analysed waters correspond to Ist quality class, which reflect a very good ecological status. Because of the high content of sulphate, calcium and magnesium, water sampled from Caprisoara creek corresponds to Vth class (based on SO42- content), IVth class (Ca2+ level) and IIIrd (Mg2+ concen-tration) class, indicating a bad / low / moderate ecological status. The water quality degradation of Caprisoara creek in the investigated area may be associated with several anthropic activities identified in the area, but to confirm this sources further investigations are needed

Unsupervised Detection of Outlier Images Using Multi-Order Image Transforms
Full text linkThe task of unsupervised detection of peculiar images has immediate applications to numerous scientific disciplinessuch as astronomy and biology. Here we describe a simple non-parametric method that uses multi-order imagetransforms for the purpose of automatic unsupervised detection of peculiar images in image datasets. The method isbased on computing a large set of image features from the raw pixels and the first and second order of several combinationsof image transforms. Then, the features are assigned weights based on their variance, and the peculiarity ofeach image is determined by its weighted Euclidean distance from the centroid such that the weights are computedfrom the variance. Experimental results show that features extracted from multi-order image transforms can be usedto automatically detect peculiar images in an unsupervised fashion in dierent image datasets, including faces, paintings,microscopy images, and more, and can be used to find uncommon or peculiar images in large datasets in caseswhere the target image of interest is not known. The performance of the method is superior to general methods suchas one-class SVM. Source code and data used in this paper are publicly available, and can be used as a benchmark todevelop and compare the performance of algorithms for unsupervised detection of peculiar images
Starlikeness and Convexity of Certain Classes of Meromorphically Multivalent Functions
Full text linkThe purpose of this paper is to investigate the problems of finding the order of starlikeness and the order of convexity of the products of certain meromorphically p-valent functions belonging to some interesting classes of beta-uniformly p-valent starlike functions and beta-uniformly p-valent convex functions in the open unit disk U. The main results presented in the paper are capable of being specialized suitably in order to deduce the solutions of the corresponding problems for relatively more familiar subclasses of meromorphically p-valent functions in U
