Oedema is the presence of excess fluid in the body tissues (Guyton & Hall, 1997). During long air flights, blood pools in the body tissues due to decreased muscle movement. This causes bilateral ankle oedema and results in an increased risk of deep vein thrombosis as well as discomfort to the passengers after their flight (Hope et al., 2001). Hamamelis virginica is clinically indicated as a homoeopathic remedy which acts upon the venous system (Nash, 2002). Apis mellifica, Apocynum cannabinum, Natrum muriaticum and Natrum sulphuricum are all homoeopathic remedies used in the treatment of oedema. The aim of this study is to ascertain the efficiency of the Homoeopathic complex formula, Hamamelis virginica 30cH, Apis mellifica 6cH, Apocynum cannabinum 6cH, Natrum muriaticum 6cH and Natrum sulphuricum 6cH in the treatment of swelling (bilateral oedema) in the lower extremities in women during and after long air flights. This study is a double blind, placebo controlled trial. Forty female participants, between the ages of eighteen to thirty-nine, with a previous history of ankle swelling after long air flights and who were planning long air flights of eight hours or more, were recruited by means of advertisement for this study. Participants meeting the inclusion criteria underwent an examination and were matched in terms of age and risk factors; weight, cigarette smoking, oral contraception, alcohol and coffee consumption. The participants within the matched pairs were then assigned to one of two groups. One group was randomly assigned the experimental group and the other the control. Participants were required to take six powders sublingually without water. The first powder was taken two hours before the actual flight. The second, third and fourth powders were taken every two and a half hours during the course of the fight and the fifth powder was taken after the flight landed. The sixth powder was taken the day after the flight. The participants were measured by the researcher (Appendix D), measuring the circumference of their calf, ankle and foot. The participants were instructed to do three measurements, the first on the day of their flight, the second on the day they arrive at their destination and the third, on the day after their last dose of medication. The measurements were recorded and a questionnaire completed (Appendix E). The data obtained from the participants measurement and questionnaire form was statistically analysed using the repeated measures test, paired t-test, descriptive statistics the crosstab, and the Huynh-Feldt test. Statistical analysis showed significant differences, P<0.05, between the control and medicated groups for the measurements in centimetres of the left ankle and right ankle. The results obtained from the research show that the homoeopathic complex medication in this study significantly reduces lower extremities oedema during long air flights, as compared to the control group. The control group, on the other hand, did show an increase in measurements of the lower extremities during the air flight. This implies that the placebo did not provide any benefit towards reducing the oedema of lower extremities in women during long air flights. Therefore the null hypothesis was rejected Preliminary findings suggest that the homoeopathic complex preparation of Hamamelis virginica 30cH, Apis mellifica 6cH, Apocynum cannabinum 6cH, Natrum muriaticum 6cH and Natrum sulphuricum 6cH, is effective in reducing the oedema of ankles during long air flights but more research is needed to confirm these findings. / Dr. E.M.

Magister Commercii (Industrial Psychology) - MCom(IPS) / A large body of research on staff turnover report that intention to leave the organisation is one of the key predictor’s to staff turnover (Chen & Francesco, 2003; Steel & Lounsbury, 2009). Researchers agree that when organisational commitment is high amongst staff the result is low turnover (Abdulkadir & Orkan, 2009; Culpepper, 2011; Muse & Stamper, 2007; Rhoades & Eisenberger, 2002). A strong correlation between voluntary turnover and the three organisational commitment dimensions (namely, affective, continuance and normative) was also found (Tansky & Cohen, 2001; Ucar & Otten, 2010). Organisational commitment has been identified as an important employee job related behaviour and perceived organisational support plays a vital role in enhancing employees’ organisational commitment. As employees’ commitment increases, employees feel more obligated and committed towards their organisation and products of this increased commitment are favourable benefits such as organisational effectiveness, reduced turnover, improved performance and reduced absenteeism (Yang, Wu, Chang, & Chien, 2011). The purpose of this study was to identify the relationship between perceived organisational support, organisational commitment and turnover intentions. Convenience sampling was used to identify the sample and questionnaires were used to collect the data. The questionnaires used to gain information include a biographical questionnaire; Eisenberger et al.’s Survey of Perceived Organisational Support, Meyer and Allen’s Organisational Commitment Questionnaire and Roodt’s Turnover Intentions Questionnaire. These questionnaires were administered to individuals employed as load control agents and support staff at a selected company in the aviation industry. The data was analysed using SPSS version 22. The results of the study reveal that no statistically significant relationship exists between perceived organisational support and turnover intentions amongst employees, however a statistically significant relationship between organisational commitment and its various dimensions namely, affective, continuance and normative commitment was found with turnover intentions. Furthermore, a statistically significant relationship between perceived organisational support and organisational commitment and its various dimensions namely, affective, continuous and normative commitment was also found. In addition to this both perceived organisational support and organisational commitment were found to predict turnover intentions. However, organisational commitment was found to be a stronger predictor of turnover intentions than perceived organisational support. Furthermore, when exploring the dimensions of organisational commitment and turnover intentions, normative commitment was found to be the strongest predictor of turnover intentions. Limitations of the findings are presented and possible recommendations for the organisation and future research are also provided.

The objective of this research is to quantify the LAMP’s performance when forecasting for IFR conditions at specific major airports for forecast hours one, three, six, and twelve, and further determine how the LAMP performs seasonally at those specific airports and forecast hours. Two by two contingency tables were used to calculate the Probability of Detection (POD), False Alarm Ratio (FAR), Critical Success Index (CSI), Heidke Skill Score (HSS), and Bias score. The results show that the LAMP performs relatively better in the cool season compared to the warm season consistently at each chosen airport, and that the LAMP performs worse when forecasting for West Coast airports relative to inland airports.

Spatial disorientation is the singular most common factor in human-error aviation accidents, and over ninety percent of those accidents are fatal. Despite advances in aviation over the past one hundred years in both technology and training, spatial disorientation mishaps continue at a steady pace, even though other incidents declining in frequency. Because spatial disorientation is a highly complex phenomena that involves the vestibular system, the visual system, and cognitive factors such as workload and attention, predicting spatial disorientation is extremely difficult. Likewise, exactly replicating spatial disorientation for training purposes is challenging as well as extremely dangerous and costly. The goal of this study was twofold: to understand if innate abilities can predict propensity for spatial disorientation, and to investigate the efficacy of using story-based vignettes – narratives – to train spatial disorientation to increase schematic learning in pilots. Results demonstrated that performance on a spatial orientation task such as the Direction Orientation Task (DOT) is not a reliable predictor for spatial disorientation recognition based on self-report spatial disorientation frequency. In addition, though story-based vignettes demonstrated potential for increased cue recognition over a control training event, significant differences were not found in novel spatial disorientation recognition, critical cue identification, or confidence. These findings indicate that spatial disorientation could be a completely perceptual (bottom-up) task rather than one that is both top-down and bottom-up and implies future research into the ways we describe and measure spatial disorientation in order to understand it as well as train for it.
