Perceptions And Experiences Of Nursing Students And Faculty Members Regarding Implementation Of The BS-Nursing Programme.

OBJECTIVE: To explore the perceptions and experiences of nursing students and faculty members regarding the implementation of the baccalaureate nursing programme in public-sector setting. Methods: The descriptive, exploratory, qualitative study was conducted at the Khyber Medical University, Peshawar, Pakistan, from April 15, 2020 to April 15, 2021, and comprised undergraduate nursing students and faculty members. Because of the coronavirus disease-2019 pandemic, the subjects were interviewed through telephonic call using a semi-structured interview guide. Data was analysed using the Creswell's analysis approach. RESULTS: Of the 15 subjects, 10(66.6%) were students aged 21-24 years; 7(70%) males and 3(30%) females. The remaining 5(33.3%) subjects were faculty members aged 25-45 years and with teaching experience of 1-18 years; 2(40%) males and 3(60%) females. A total of 85 codes and 17 categories emerged under 5 major themes; programme positive impacts, curriculum revamping, students' challenges, faculty challenges, and recommendations. The participants believed that the four-year undergraduate nursing programme would improve the profession and quality of nursing care. Some perceived challenges were also pointed out regarding the curriculum, faculty, infrastructure and learning resources. Conclusion: Through the provision of an updated curriculum, qualified teaching faculty, appropriate learning resources and proper infrastructure, the undergraduate nursing programme can be successfully implemented in Pakistan.

Ultralow Absorption Coefficient and Temperature Dependence of Radiative Recombination of CH3NH3PbI3 Perovskite from Photoluminescence.

Spectrally resolved photoluminescence is used to measure the band-to-band absorption coefficient α(BB)(ℏω) of organic-inorganic hybrid perovskite methylammonium lead iodide (CH3NH3PbI3) films from 675 to 1400 nm. Unlike other methods used to extract the absorption coefficient, photoluminescence is only affected by band-to-band absorption and is capable of detecting absorption events at very low energy levels. Absorption coefficients as low as 10⁻¹4 cm⁻¹ are detected at room temperature for long wavelengths, which is 14 orders of magnitude lower than reported values at shorter wavelengths. The temperature dependence of α(BB)(ℏω) is calculated from the photoluminescence spectra of CH3NH3PbI3 in the temperature range 80-360 K. Based on the temperature-dependent α(BB)(ℏω), the product of the radiative recombination coefficient and square of the intrinsic carrier density, B(T) × n(i)², is also obtained.
