In this paper, the authors are exploring emerging trends in data utilising longitudinal analysis.Longitudinal studies are typically observational studies wherein a participant's outcomes, and possible treatments or exposures, are collected at multiple times on the same individual. These studies have no limit on the timespan and as such, can last up to several decades. Though shorter time frames are not recommended, the key is for the study to extend beyond a singular time point, ideally three or more[1]. Conducting longitudinal studies are beneficial as it allows one to follow subjects in real time, which allows researchers to have a better understanding of the sequence of events[1].
Piano grass (Themeda arguens), reputed to have been introduced to Jamaica as packing material in an imported piano1 . There are about 27 varieties of this highly invasive grass/weed worldwide[1] and in Jamaica the species previously identified as Themeda arguens is of concern as it has progressively taken over lawns, pastures and roadsides [1]. The grass is of particular concern to livestock farmers due to its highly invasive and aggressive nature and the concomitant negative effect on livestock productivity, especially during its annual seeding period (November/December – April) [2], when the palatability of the grass diminishes significantly and the seed awns can cause severe damage to the mouth when consumed, and feet of livestock [2], sometimes requiring veterinary intervention.
At the inception of automated solar tracking in the 1970’s, geometric architectures with pair(/s) of solid-state photo-sensitive devices were constructed and used to detect the sun’s position. As an alternative in recent years, cameras have been used to capture and process live sky images to detect the sun’s position. When the sky is cloudy however, both approaches are prone to errors and sometimes require human intervention which tend to reduce the trackers’ economic viability [1].
Oral malodour called halitosis, and commonly referred to as ‘bad breath’, is a socially offensive and discriminating occurrence that requires effective management for health improvement and avoidance of debasing stratification of sufferer. Halitosis has been reported to be prevalent in up to 50% of the general population in the USA, and about 6-23% in China. Between 80% and 85% of halitosis cases are caused by intraoral conditions. Literature on halitosis in Jamaica is either scarce or non-existent. Prior to the COVID-19 pandemic, a common malodour that seemed to be spreading among persons through oral interaction by face-to-face contact with a sufferer was observed among the general populace in Mandeville, Manchester, Jamaica.
