Nursing Students' Experiences of Horizontal Violence and Occupational Belonging During Clinical Placements
(Wolters Kluwer Medknow Publications, 2022) Sukut, O.; Ayhan, C.
Background: Horizontal violence has negatively affected the students' active learning, interpersonal relationship, and occupational belonging. However, little attention has been paid to the relationship between horizontal violence and occupational belonging among nursing students. Objective: The objective of this study was to explore the frequency, types, perpetrators, effects, and responses of horizontal violence experienced by nursing students and the relationship between occupational belonging and horizontal violence. Materials and Methods: The present study used a descriptive, cross-sectional survey design. The data were collected from the 277 undergraduate nursing students selected by convenience sampling method using personal characteristics form, horizontal violence survey, and occupational belonging subscale at nursing faculty in Istanbul. Results: The first three horizontal violence behaviors experienced by nursing students were found, respectively: being forced to do trivial and unimportant work which are not the students' responsibility (84.1%), being exposed to sarcastic remarks by nurses (80.9%) and unwillingness of the nurse to help and lack of support (80.9%) and being ignored by nurses (77.3%). Nearly half of the students (48.4%) considered leaving nursing profession as a result of horizontal violence. There was a negative relation between horizontal violence and occupational belonging (P < 0.05). As horizontal violence scores increased, occupational belonging scores decreased. Conclusions: Findings from this study shown that horizontal violence decreasing occupational belonging, and so nursing students consider leaving nursing profession or education. Further studies are needed to better demonstrate addressing the horizontal violence bilaterally and the effective preventive interventions. © Medknow. All rights reserved.
Studies on the Effect of Npk Fertilization on Frost Tolerance in the Hacihalilodlu Apricot (Prunus Armenica L.) Cultivar
(International Society for Horticultural Science, 2000) Akća, Y.; Murat Asma, B.; Ayhan, C.
This study was conducted to determine the effect of NPK fertilization on the frost tolerance in the HacyhaliloSlu apricot cultivar in the years 1996-1997. The fertilizer treatments comprised all factorial combinations of 4 levels of N (No=0.0, N1=0.2, N2=0.4 and N3=0.6 kg of N per tree per year), 3 levels of P (P,=0.2 P2=0..4 and P3=0.6 kg of P2O5 and 3 levels of K (Ki=0.4, K2=0.8 and K3= 1.6 kg K2O). These treatments were applied to the trees between 1994-1997. Samples of two twigs were collected and exposed to artificial freezing tests, periodically between December and March. The artificial freezing was made at -10C° for a duration of 7 hours. Statistically significant differences were found between the frost tolerance of NPK-treated flower buds of the HacyhaliloQlu cv. The frost tolerance abilities, at the investigated NPK doses, were found to be higher in January and lower in December and March. Potassium and phosphorus fertilizers had significant effects on the frost tolerance of flower buds. Potassium fertilizer played the most important role on frost tolerance, compared with nitrogen or phosphorus fertilizers. The results indicated that, the frost tolerance of flower buds following K2O applications was higher than that of buds treated with other NPK doses. Lower survival percentages of buds were found with nitrogen applications. The frost tolerance ability was found to be lower following fertilization at the higher doses of nitrogen. In all the investigated NPK doses, the level of K and Fe increased from January to February, in parallel with the frost tolerance ability of the flower buds, but decreased in November and March.
