Visualization of personality and phobia type clustering with GMM and spectral
No full textPersonality traits, the unique characteristics defining individuals, have intrigued philosophers and scholars for centuries. With recent advances in machine learning, there is an opportunity to revolutionize how we understand and differentiate personality traits. This study seeks to develop a robust cluster analysis approach (unsupervised learning) to efficiently and accurately classify individuals based on their personality traits, overcoming the limitations of manual classification. The problem at hand is to create a system that can handle the subjective nature of qualitative personality data, providing insights into how people interact, collaborate, and behave in various social contexts and thus increase learning opportunities. To achieve this, various unsupervised clustering techniques, including spectral clustering and Gaussian mixture models, will be employed to identify similarities in unlabeled data collected through interview questions. The clustering approach is crucial in helping policy makers to identify suitable approaches to improve teamwork efficiency in both educational institutions and job industries

Habitat preferences of freshwater prawn, Macrobrachium spp. in the Petagas River, Sabah, Malaysia
No full textMacrobrachium species is one of the most abundant and valuable cultured freshwater prawns in the world, serving as a high-value food resource. A study conducted in Petagas River, Sabah aimed to determine the habitat preferences of this freshwater prawn, as suitable habitats play an important role for the survival and growth of each species. Six stations were selected representing different habitats: vegetation or shades, dead logs or tree roots and no shelter, consisting only of mud or sand. Prawns were caught using fish traps equipped with two entrance funnels, left overnight, and retrieved the next day. Data were analyzed using SPSS, involving Kruskal-Wallis and Mann-Whitney U tests. Habitats with the presence of dead logs or tree roots portrayed the highest percentage of adult individuals caught (54.43%), followed by those with vegetation (27.22%), and mud (18.35%). Additionally, sstatistical analyses revealed a significant difference in the number of adult individuals among all stations (Kruskal-Wallis; p 0.05). This study showed that freshwater prawn, Macrobrachium spp. in Petagas River exhibit a preference for habitats that include dead logs or tree roots serving as shelter over those containing only vegetation and mud or sand

Evaluating mcmc convergence in a bayesian model of st-elevation myocardial infarction female patients in Malaysia
No full textThe majority of research that looked at the Bayesian Markov Chain Monte Carlo (MCMC) approach for prognostic modelling of cardiovascular disease only focused on the use of the Bayesian approach in variable selection, model selection, and prior distribution selection. But very few of this research has looked at the Markov chains' convergence in the model. In this study, convergence diagnostics were carried out to evaluate the convergence of Markov chains using both visual inspection and additional diagnostics. The National Cardiovascular Disease Database-Acute Coronary Syndrome (NCVD-ACS) registry, which included 1248 female patients with ST-Elevation Myocardial Infarction (STEMI) between 2006 and 2013, was used for this study's analysis. The multivariate Bayesian model identified six significant variables: dyslipidaemia, myocardial infarction, smoking, renal disease, Killip class, and age group. The trace plots did not reveal any distinctive patterns based on these significant variables, and the model's MCMC mixing is typically good. While for the autocorrelation plots, mild autocorrelations for age group, Killip IV, as well as the intercept term in the model. Since there were only mild autocorrelations, no thinning is needed. Also, the Geweke diagnostic showed that the chain is divided into two windows containing a set fraction of the first and last iterations which produced standard Z-scores. The Geweke diagnostic did not provide evidence of non-convergence, as none of the Z-scores fell in the extreme tails of the N (0,1). In this study, a number of plots and additional diagnostic tools showed that the Markov chains have reached convergence, which is relevant to the general use of the MCMC approach
Identifying priority sites for whale shark ship collision management globally
No full textThe expansion of the world’s merchant fleet poses a great threat to the ocean’s biodiversity. Collisions between ships and marine megafauna can have population-level consequences for vulnerable species. The Endangered whale shark (Rhincodon typus) shares a circumglobal distribution with this expanding fleet and tracking of movement pathways has shown that large vessel collisions pose a major threat to the species. However, it is not yet known whether they are also at risk within aggregation sites, where up to 400 individuals can gather to feed on seasonal bursts of planktonic productivity. These “constellation” sites are of significant ecological, socioeconomic and cultural value. Here, through expert elicitation, we gathered information from most known constellation sites for this species across the world (>50 constellations and >13,000 individual whale sharks). We defined the spatial boundaries of these sites and their overlap with shipping traffic. Sites were then ranked based on relative levels of potential collision danger posed to whale sharks in the area. Our results showed that researchers and resource managers may underestimate the threat posed by large ship collisions due to a lack of direct evidence, such as injuries or witness accounts, which are available for other, sub-lethal threat categories. We found that constellations in the Arabian Sea and adjacent waters, the Gulf of Mexico, the Gulf of California, and Southeast and East Asia, had the greatest level of collision threat. We also identified 39 sites where peaks in shipping activity coincided with peak seasonal occurrences of whale sharks, sometimes across several months. Simulated collision mitigation options estimated potentially minimal impact to industry, as most whale shark core habitat areas were small. Given the threat posed by vessel collisions, a coordinated, multi-national approach to mitigation is needed within priority whale shark habitats to ensure collision protection for the species
Identifying populations of the marble goby, oxyeleotris marmorata (Bleeker, 1852) by otolith shape analysis and their spawning seasons in Likas Bay, Sabah, Malaysia
No full textThe marble goby, Oxyeleotris marmorata is native to fresh and brackish waters of Southeast Asia. The yield of wild O. marmorata has been decreased drastically and urgent conservation actions are required to prevent extinction. In the Likas Bay, Oyeleotris marmorata is caught throughout the year by local fishermen using various fishing gears. In fisheries management, population is a fundamental biological unit and population identification of a species is important. The population structure of this marine stock was determined by otolith shape analysis and their spawning season in the Likas Bay was determined by ovarian observations. A total of 147 specimens were procured between 2018 and 2019; size ranged from 443 g to 3,264 g BW. The curvature index of the otoliths was analyzed by Bhattacharya’s method and found that the frequency distribution of curvature indices is a mixture of two normal components, indicating two different populations. The specimens with mature or spent ovaries were found in samples collected in January – February and September, showing two spawning seasons. The age of each specimen was estimated by counting the vertebral annuli. The estimated age ranged from 5 to 14 years. The minimum size and age of spawners was 338 mm TL, 499 g BW and 5 years old. The findings obtained in this study provide basic biological parameters of O. marmorata populations in Likas Ba
