Characterization of p-valent q-starlike functions through Hadamard product and Poisson distribution

This paper presents significant advancement in the study of multivalent functions by introducing three new subclasses of p-valent q-starlike functions, defined with respect to higher-order q-derivatives within the open unit disk of the complex plane (|z| <1). We utilized the Poisson distribution as a coefficient and applied the Hadmard product to derive several essential properties of these q-starlike functions, including distortion theorems and radius problems, particularly in case with negative coefficients. These findings enhance our understanding of the function behaviour and contribute to the broader mathematical discourse

The effect of a stress ball on pain and anxiety during sharp debridement in patients with diabetic foot ulcers: A randomized controlled, single-blind study

Objective: The aim of this study was to investigate the effect of using a stress ball during sharp debridement on the pain and anxiety in patients with diabetic foot ulcers. Methods: This study with a randomized, controlled and single-blind design was conducted at a single-center on patients diagnosed with diabetic foot ulcers who were being treated at the endocrinology and metabolic diseases clinic of a university hospital. Patients in the intervention group started using a stress ball before the debridement procedure and continued to use it until the procedure ended. No intervention was made to the patients in the control group. Data were collected by using the Descriptive Information Form, Diabetic Foot Meggit-Wagner Classification, Visual Analogue Scale (VAS), and State Anxiety Inventory (STAI). Results: The study was completed with a total of 76 patients, 38 each in the intervention and control groups. The use of stress balls led to a reduction in anxiety and pain symptoms in the intervention group. The anxiety score of the patients in the intervention group was also found to be statistically significantly lower than those in the control group after the procedure (p = 0.008; η2 = 0,091). The VAS scores of the patients in the intervention group were found to be statistically significantly lower than those in the control group both during (p < 0.001; η2 = 0.348) and after (p < 0.001; η2 = 0.438) the procedure. Conclusions: The use of a stress ball was found to be an effective method of reducing the level of pain and anxiety that occurs during the sharp debridement procedure. Stress ball application is a practical, easy, and cost-effective non-pharmacological method. Clinical trial number: The study was recorded in the ClinicalTrials.gov website with the number NCT06316115. © 2025 The Author

The mediating role of affective commitment in the relationship between perceived employability and intention to quit in the hospitality industry

This study explores the mediating role of affective commitment in the relationship between perceived employability and the intention to quit, focusing on the tourism sector-a field often marked by high employee turnover. Data were collected from 615 employees working in 4- and 5star hotels in Antalya and Mu & gbreve;la, T & uuml;rkiye. The relationships among perceived employability, affective commitment, and intention to quit were analysed using SPSS and AMOS. The results revealed that affective commitment significantly mediates the link between perceived employability and turnover intentions. While high perceived employability generally increases employees' intentions to leave their jobs, strong affective commitment was shown to offset this effect, thereby reducing the likelihood of turnover. Thesefindings highlight the need for HR strategies that prioritise building and maintaining affective commitment among employees, particularly in high-mobility industries like hospitality, to retain highly employable staff. By offering a deeper understanding of how affective commitment can buffer the turnover risks associated with high employability, this study provides practical insights for HR practitioners in industries facing labour retention challenges

The effect of hygienic care practices given to stroke patients on vital signs of patients: A self-comparison pre-experimental study

Background: Hygiene and skin care are crucial for stroke patients in intensive care, yet the effects of bathing practices on vital signs in mechanically ventilated stroke patients remain underexplored. Aim: This study aimed to assess the effects of full bed baths and wiping baths on vital signs in stroke patients. Study design: A self-comparison pre-experimental study was conducted with 90 stroke patients treated in three intensive care units at a Turkish hospital between 10 January 2021 and 01 January 2022. Patients received either a full bed bath (first measurement day) or a wiping bath (second and third measurement days). Vital signs and arterial blood gas values were measured before and after each bath. Results: Of the participants, 55.5% were male, with a mean age of 64.2 ± 14.8 years. Significant changes in heart rate, systolic blood pressure, diastolic blood pressure and body temperature were observed after the full bed bath (heart rate: λ = 0.156, F = 43.940; systolic BP: λ = 0.484, F = 17.981; diastolic blood pressure: λ = 0.835, F = 7.216; body temperature: λ = 0.97, F = 142.92; p < .001). Similarly, wiping baths resulted in significant changes (heart rate: λ = 0.354, F = 34.776; systolic blood pressure: λ = 0.384, F = 16.372; diastolic blood pressure: λ = 0.492, F = 17.603; body temperature: λ = 0.236, F = 176.765; p < .001). Arterial blood gas changes were significant after wiping baths on Day three (pH: t = 3.351, p = .001; PaO2: t = 2.400, p = .018). Conclusions: Both full and wiping bed baths significantly affect vital signs and arterial blood gases in stroke patients. Nurses should tailor bathing practices to patient needs, continuously monitoring vital signs. Relevance to clinical practice: This study highlights how bathing practices impact vital signs and arterial blood gases in intensive care patients. It emphasizes tailoring interventions to patient needs and preferences, as full baths may suit some, while wiping baths offer advantages, particularly for blood pH and PaO2 levels

Expectation formulas for q-probability distributions: A new extension via Andrews-Askey integral

In this paper, we utilize the q-Chu-Vandermonde formula to derive a novel expectation formula for the q-probability distribution W ( x , y ; q ), extending previously known results. Several applications are presented, including a broader generalization of the Andrews-Askey integral. Although fractional q-calculus is not directly employed in this work, its potential for future extensions is discussed, as non-integer order derivatives and integrals could offer deeper insights into q-series and probability distributions

Examining the role of co-worker support and occupational outcome expectancy on career regret

PurposeThis paper aims to explore the mechanisms that explain the effects of physicians who feel supported by their co-workers on their professional outcome expectations and their ability to be more successful in their chosen career, in the context of Social Cognitive Career Theory (SCCT).Design/methodology/approachThe population of the study is physicians working in hospitals in Ankara. There are 37 hospitals under the Ministry of Health in the province. A total of 5,092 physicians work in these hospitals. In this study in which questionnaire technique was used, data were collected from 400 physicians by convenience sampling method. The data obtained were analysed by means of AMOS 22.0 and SPSS 26.0 package programs.FindingsAs a result of the regression analyses, it was determined that physicians' professional outcome expectancy had a positive and significant effect on career regret. In addition, it was determined that the perceived co-worker support variable did not have a moderating role effect in the relationship between physicians' professional outcome expectancy and career regret.Research limitations/implicationsIn this study, the moderating role of co-worker support in the effect of physicians' professional outcome expectations on career regrets is examined. Therefore, the sampling frame is limited to physicians.Practical implicationsBased on the fact that professional outcome expectation and co-worker support are very important variables for individuals with career regret, it emphasises that management activities carried out in health institutions should be carried out in a way that supports the career development of employees.Originality/valueThe tasks that physicians perform include many challenging elements. Therefore, the support they receive from their co-workers is critically important

L-shell photoionisation cross sections in the S+, S2+, S3+ isonuclear sequence

We present absolute L-shell photoionisation cross sections for the S+, S2+, S3+ ions. The cross sections were obtained using the monochromatised photon beam delivered by the SOLEIL synchrotron source coupled with an ion beam extracted from an electron cyclotron resonance source (ECRIS) in the merged dual-beam configuration. The cross sections for single, double and triple ionisation were measured and combined to generate total photoionisation cross sections. For each of the S+, S2+ and S3+ ions, the photon energy regions corresponding to the excitation and ionisation of a 2p or a 2s electron (similar to 175-230 eV) were investigated. The experimental results are interpreted with the help of multiconfigurational Dirac-Fock (MCDF) and Breit-Pauli R-Matrix (BPRM) or Dirac R-Matrix (DARC) theoretical calculations. The former generates photoabsorption cross sections from eigenenergies and eigenfunctions obtained by solving variationally the multiconfiguration Dirac Hamiltonian while the latter calculate cross sections for photon scattering by atoms. The cross sectional spectra feature rich resonance structures with narrow natural widths (typically nd excitations below and up to the 2p thresholds. This behaviour is consistent with the large number of inner-shell states based on correlation and spin-orbit mixed configurations having three open subshells. Strong and wide (typically similar to 1 eV) Rydberg series of resonances due to 2s -> np excitations dominate above the 2p threshold
