- Description: A person’s career takes up a large portion of his or her life for a minimum of 8 hours per day. A large portion of their time is spent performing their duties which are often accompanied by various demands or pressure that can result in an employee experiencing stress. Over time this build-up of stress due to job demands affects their ability to perform at work. This study aimed to identify, explore and describe the factors that facilitate the resilience of healthcare professionals working at a Campus Health Service at a Higher Education Institution. An exploratory descriptive study consisting of a qualitative nature was employed. Data was obtained from semi-structured interviews. The questions that were posed to participants read as follows: (1) “Tell me about the demands placed on you in your current work situation”, (2) “How do you cope with the demands placed on you?”, (3) “What can be done to assist you to cope better at work?”, and lastly (4) “Any additional questions/comments?”. The fourth question was added by the researcher in order for participants to have the opportunity to add to what they have said previously. Data was gathered until data saturation was reached. Tesch’s model of content analysis as well as Guba’s model of trustworthiness was employed, in order to analyse the data. An independent coder was subsequently employed to ensure the trustworthiness of the data. The findings revealed that all participants found workplace demands to be stressful, in terms of physical, emotional and time-related demands placed on them. Participants identified strategies that could help them cope with their demands such as open air activities, debriefing with colleagues or making use of a wellness line, maintaining a positive attitude, support from management and colleagues, the ability to practice initiative and autonomous decision-making, and lastly, religious practices. In addition, participants made recommendations on how employers can help relieve their stress. The recommendations included developing an in-house wellness programme, providing sufficient staff of the correct categories, providing adequate facilities and equipment to improve efficiency, providing developmental opportunities, scheduling training programmes for less busy times of the year, and lastly, introducing elements of structured flexi-time for employees.

Philosophies that inform discipline strategies among teachers

- Description: Numerous teachers in South Africa are experiencing ill‐discipline within the classroom environment. They are not receiving the necessary support and guidance from the relevant departments, and thus, rely on their own reactive measures to manage the disruptive behaviour present in the classroom. Previous studies have shown that the South African Education Department has not provided all teachers with the necessary training needed to implement the new discipline strategies proposed by the Department of Education. Therefore, teachers rely on what they perceive to be effective in maintaining discipline, which is an indication of their personal teaching philosophy, as they base their own knowledge on what they have experienced and learnt in the past. This study followed a qualitative enquiry, which is descriptive and explorative. The data generation tools that were utilised for the study were, ‘drawing’ and ‘photo album’, both of which represent visual methodology activities. Furthermore, the primary aim of the study is to determine the underlying teaching philosophies that inform selected township teachers’ approaches to discipline in their classrooms. However, the findings indicated that the use of corporal punishment is still visibly prevalent in this township school. Even though it was revealed that the prominent teaching philosophy was not that of fundamental pedagogics, but featured somewhere in between the humanising pedagogy and Noddings’ theory of caring, the effects of teaching during Apartheid under the principles of fundamental pedagogics is still existent in the township.

The presence of silver nanoparticles resulted in reduced fluorescence, and increased triplet and singlet oxygen quantum yields. The conjugates were further electrospun into polystyrene fibers, and employed for the photodegradation of methyl orange. The photodegradation of methyl orange using all functionalized fibers followed first order kinetics, and was faster when the conjugates with silver nanoparticles were used. The non-peripherally substituted 3-TCbZnPc gave better photocatalytic activity compared to its peripherally substituted counterpart (4-TCbZnPc). The hybrid electrospun fibers provide great potential as active photocatalysts for degrading organic pollutants. , Online publication is available at http://dx.doi.org/10.1016/j.molcata.2014.07.031

- Description: Photocatalytic degradation of Rhodamine 6G using unconjugated zinc tetraamino phthalocyanine (ZnTAPc) or when conjugated to Ag nanoparticles (ZnTAPc–AgNPs) is reported. Upon conjugating ZnTAPc to silver nanoparticles, the singlet oxygen production of the phthalocyanine was slightly increased. ZnTAPc and ZnTAPc–AgNPs were immobilized onto chitosan beads for ease of recovery after photocatalysis. Chitosan beads were characterized by FTIR, XRD and TGA. The photodegradation of Rhodamine 6G was used to evaluate the efficiency of the immobilized photocatalysts. In the presence of AgNPs, the photodegradation of Rhodamine 6G was enhanced. The apparent rates (k) were found to be 8.51 × 10−8 and 1.61 × 10−7 mol L−1 min−1 for chitosan supported ZnTAPc or ZnTAPc–AgNPs, respectively. The observation of good photocatalytic activity of the ZnTAPc when immobilized on chitosan proves the uncompromised efficiency of the photocatalysts even when confined in beads, showing great potential for the functionalized beads as heterogeneous catalysts. , Original publication is available at http://dx.doi.org/10.1016/j.molcata.2015.01.017

Photodynamic antimicrobial chemotherapy activity of gallium tetra-(4-carboxyphenyl) porphyrin when conjugated to differently shaped platinum nanoparticles

The resulting conjugates were used for photodynamic antimicrobial chemotherapy against Staphylococcus aureus. The degree of photo-inactivation is dependent on concentration of the conjugates, light dose (fluence) and illumination time. The log reduction obtained for ClGaTCPP when conjugated to cubic PtNPs was 4.64 log (which indicate 99.99% of the bacteria have been killed), which is much higher than 3.94 log unit for ClGaTCPP-Hexagonal PtNPs and 3.31 log units for ClGaTCPP-Unshaped PtNPs.
