Self-regulation and psychological resilience as predictors of the academic self-efficacy of university students
(2024) Sayın Kılıç, Mine; Erduran Tekin, Özge; Keçeci, Berra
The purpose of this study is to determine the effects of the self regulation and psychological resilience levels of university students on their academic self-efficacy. The sample of the correlational study consisted of a total of 520 university students, 414 female and 106 male. The Self-Regulation Scale, the Brief Resilience Scale, and the Academic Self-Efficacy Scale were used to collect data. In the study, independent groups t-test was applied to determine the differences between genders regarding the variables, Pearson Correlation Analysis was applied to examine the correlation between variables, and Hierarchical Regression Analysis was applied to examine its prediction. It was determined that the psychological resilience levels of the participants varied based on their genders, while their self-regulation and self-efficacy levels did not differ based on the gender variable. Self-regulation and psychological resilience were found to be associated with academic self-efficacy, where self-regulation and psychological resilience together predicted academic self-efficacy.
Log-Harmonic mappings associated with the sine function
(2024) Kumar, Sushil; Çetinkaya, Asena; Özkan Uçar, Hatice Esra
In this paper, we define new subclasses STlh(s) and CSTlh(s) of sine starlike log-harmonic mappings and sine close-to-starlike log-harmonic mappings, respectively, defined in the open unit disc D. We investigate representation theorem and integral representation theorem for functions in the class STlh(s). Further, we determine radius of starlikeness for functions in the classes STlh(s) and CSTlh(s).
A study on harmonic functions
(Bulgarian Academy of Sciences, 2024) Uçar, Mehmet Fatih; Özkan Uçar, Hatice Esra
The class of functions that have bounded boundary rotation and bounded radius rotation are the generalization of the convex and the starlike functions, respectively. The concept of such functions was introduced by L¨owner [1]. But he did not use the present terminology. It was Paatero [2,3] who systematically developed their properties and made an exhaustive study of the class of functions that have bounded boundary rotation. We will examine in this paper, the subclass of SH that is related to the class of functions that have bounded radius rotation.
Perspectives of nurse leaders regarding time management in nursing: Qualitative research
(Yönetici Hemşireler Derneği, 2024) Aydoğdu, Ana Luiza Ferreira
Aim: To describe the experiences and opinions of nurses in leadership positions about time management and provide recommendations to avoid wasting time in the nursing field. Method: This is a qualitative descriptive study. It involved self-descriptions of open-ended questions of 32 nurses in leadership positions from Rio de Janeiro, Brazil. Data were interpreted through content analysis. Results: Data were organized into five themes: (1) Factors that facilitate time management in nursing, (2) Factors that hinder time management in nursing, (3) Impairments to care due to inappropriate use of time, (4) Differences in relation to other health professions, and (5) Measures for optimizing time management in nursing. Conclusion: Nursing shortages, work overload, intercurrences, disorganization, and distractions are barriers to managing time. Nurse participants feel undervalued, have low salaries, and need to have more than one job to maintain themselves, and all these factors are obstacles to the adequate allocation of time that threaten the quality of care.
Development of analytical strategy for the determination of cadmium by flame atomic absorption spectrometry after dithizone/deep eutectic solvent probe based liquid phase microextraction
(Taylor & Francis, 2024) Akbıyık, Hilal; Serbest, Hakan; Kılınç, Yağmur; Oflu, Sude; Gürsoy, Selim; Özdoğan, Nizamettin; Çetin, Gülten; Bakırdere, Sezgin
Liquid phase microextraction (LPME) with a dithizone/deep eutecticsolvent (DTZ-DES)-based probe was employed for the determinationof trace cadmium by flame atomic absorption spectrometry (FAAS).All extraction parameters were univariately optimized to achieve thehighest efficiency and the limits of detection and quantification were3.5 and 11.8 ng mL−1. Good linearity was obtained from 10 to200 ng mL−1 with a regression coefficient (R2) of 0.9979. The sensitiv-ity of FAAS system was improved 26.9-fold by the microextractionprocedure. The accuracy and applicability of the method were inves-tigated with recovery experiments carried out using corn silk teaextracts. The recovery values with matrix matching calibration werefrom 81.3 to 114.3%, demonstrating that this environmentallyfriendly method is applicable for determination of cadmium in teasamples with good accuracy.
