There is an increased call for improving the environment in which nursing students learn the clinical skills. Clinical practice in the clinical placement sites should allow students to apply their theoretical knowledge in a real environment, develop nursing skills and clinical reasoning, and observe and adapt the professional role. This study aimed at identifying the factors influencing performance in clinical practice among preservice diploma nursing students in Northern Tanzania. This study relied on a cross-sectional analysis of data collected from nursing schools in Northern Tanzania in which 208 (123 nursing students and 85 nurse tutors) participants were recruited in the study. Data was gathered using a self-administered questionnaire which collected information on sociodemographic characteristics and factors influencing clinical practice categorized in students’ factors, hospital based factors, social-economic factors, and nurse tutors opinions assessed. Descriptive analyses and chi-square test were employed to understand the background information of the sample and association between variables. Majority of the nursing students (84.4%) agreed that clinical placement offers students adequate opportunity for clinical practical learning. Barriers to effective clinical learning was reported by 70.1% of the participants and the barriers include student factors such as lack of self-confidence and absenteeism, school factors such as improper supervision, and poor preparation of clinical instructors or clinical facility factors. We found a significant association between type of barrier and gender (chi-square 0.786, p=0.020). More male nursing students (62.1%) significantly reported unsupportive environment as a barrier and anxiety was more common in female nursing students (48.9%) (p=0.020). Reporting of barriers to effective clinical learning by students from different schools of nursing was not significant (P=0.696). In addition, age of participants did not have significant association with effective clinical practice (p=0.606). Student’s factors and placement based factors played an important role to influence clinical learning experiences. Offering preclinical orientation, distributing and clarifying clinical learning objectives to students, and frequent visits and supervision of students in clinical area may improve student learning experience in clinical placement. In addition, tailoring the interventions to gender may improve learning experiences.

Tracy and Doremus have demonstrated chemical bonding between bone and hydroxylapatite with transmission electron microscopy. Now researchers ponder how to improve upon this bond in turn improving the life expectancy and biocompatibility of implantable orthopedic devices.This report focuses on a study of the- chemical influences on the interfacial integrity and strength. Pure hydroxylapatite (HAP), magnesium doped HAP, strontium doped HAP, bioglass and medical grade titanium cylinders were implanted into the tibial cortices of New Zealand white rabbits. After 12 weeks, the implants were retrieved for a scanning electron microscopy study coupled with energy dispersive spectroscopy.Following sacrifice and careful retrieval, the samples were dehydrated through a graduated series starting with 50% ethanol and continuing through 60, 70, 80, 90, 95, and 100% ethanol over a period of two days. The samples were embedded in LR White. Again a graduated series was used with solutions of 50, 75 and 100% LR White diluted in ethanol.

Abstract This qualitative study examined student perceptions regarding a hybrid classroom format in which part of their learning took place in a traditional classroom and part of their learning occurred in an online platform. Pre-course and post-course anonymous essays suggest that students may be open to learning in this context; however, they have specific concerns as well. Students raised issues regarding faculty communication patterns, learning styles, and the value of clear connections between online and traditional learning experiences. Student concerns and feedback need to be addressed through the course design and by the instructor in order for them to have a positive learning experience in a hybrid format course.

Electrodermal and electroencephalic responsivity to sound and to light was studied in 96 normal-hearing adults in three separate sessions. The subjects were subdivided into equal groups of white men, white women, colored men, and colored women. A 1 000 cps pure tone was the conditioned stimulus in two sessions and white light was used in a third session. Heat was the unconditioned stimulus in all sessions. Previously, an inverse relation had been found in white men between the prominence of alpha rhythm in the EEG and the ease with which electrodermal responses could be elicited. This relation did not hold true for white women. The main purpose of the present study was to answer the following questions: (1) are the previous findings on white subjects applicable to colored subjects? (2) are subjects who are most (or least) responsive electrophysiologically on one day equally responsive (or unresponsive) on another day? and (3) are subjects who are most (or least) responsive to sound equally responsive (or unresponsive) to light? In general, each question was answered affirmatively. Other factors influencing responsivity were also studied.
