Classification of mangrove species based on leaf fractal dimensions
Get PDF The study utilized the fractal dimensions of the leaves of mangrove species locally found in the City of Tangub to determine if the same can be used for classification purposes. The species used were: Rhizophora mucronata, Avicennia marina, Pemphis acidula, Sonneratia alba and Acrostichum aureum. Findings revealed that fractal dimensions can be used to differentiate one mangrove species from another through their leaf roughness (f =14.400, p = 0.000). However, leaf fractal dimensions alone cannot differentiate the following mangrove species within groups: {Rhizopora mucronata and Avicennia marina}, {Acrostichum aureum and Pemphis acidula}, {Sonneratia alba}. In effect, leaf fractal dimensions identify only the following groupings: {Rhizopora mucronata, Avicennia marina}, {Acrostichum aureum, Pemphis acidula} and {Sonneratia alba}. The results may be due to the small sample sizes used for some of the mangrove species. In particular, the standard deviations of the fractal dimensions of the Sonneratia alba and Avicennia marina may have been over-estimated because of the small sample sizes. The empirical probability of misclassification using the technique is approximately 4.5%
Politico-economic influence and social outcome of English language among Filipinos: An autoethnography
Get PDFDeeply rooted with the influence of the American culture to Philippine Education, most curricula are centered on the English language as the medium of instruction. Until today, most of the classes are taught in English while inconspicuously discourage the use of the lingua franca during discussions and even within school premises. The culture of reverse ethnocentricity in communication is motivated by the assumed status symbol in the community. This autoethnographic study analyzed the positive and ill effects of English-centered curriculum among bilingual and multilingual Filipino students. Noble consequences include: (1) considerably comprehensible to good command of the International language; (2) prodigious chances of employability in foreign countries; and (3) tourism, education and business attraction. Proficiency in the English language as a status symbol has unfavorable effects which include: (1) poor mastery of the lingua franca both in oral and written communication; (2) perceiving the lingua franca as a second-class language; (3) stereotypes and inferiority among non-English and poor-English speaker; (4) challenged cultural identity; and (5) threatened nationalism and patriotism
The dynamics of barter trade among Cebuano farmers
Get PDFBarter is an old process of doing business in the olden times without the use of money. It is surprising to note that, during this age of technology and borderless commercialization, barter is still useful and is even used with technology. The study aimed to document the barter system used by Cebuano farmers to find out if this business process is still profitable. Moreover, both the economic and social implications are recorded in relation to Filipino culture. The findings revealed three types of barter: (1) goods with goods; (2) goods with service; and (3) extended barter system. Moreover, the farmers from northern and southern Cebu realized that the barter system was more profitable for them than selling their goods directly to consumers for money. Barter system revealed the peace-loving nature and generosity of Cebuanos
Determinants of human immunodeficiency virus prevalence
Get PDFHuman Immunodeficiency Virus prevalence was predicted using cluster analysis technique. A retrospective design was employed. We deployed surrogate measures for social, economic, political and quality of life. Data mining strategies were trailed to gather data. Factors that affect HIV prevalence were represented with surrogate measures by brainstorming activity. Data were taken from world reports from reliable sources. Using an algorithm, data were analyzed using MiniTab software: partitioning, centroid-based, hierarchical and density based methods. This article introduced three contending models on the interplay of the factors towards its influence on HIV prevalence. It culminates with the integration of a holistic model, which can provide a theoretical basis in predicting HIV prevalence. An integrative model was elevated from its substantial form to a more formal application. From HIV prevalence to communicable disease prevalence, this provides a more wide application
Variation in well-being across Law
Get PDFThe study looks into the difference in the well-being of officers in various Law-Enforcement Agencies in terms of salary, workplace, opportunities and recruitment processes. The Law-Enforcement Agencies are: the Philippine National Police, the Bureau of Jail Management and Penology, and the Bureau of Fire Protection in Cebu City. The rationale for this study is motivated by the observation that more aspirants want to be accommodated in the PNP, then in the other terms of agencies. More over because of the overwhelming number of aspirants to the PNP who cannot be accommodated in terms of the quota, many Criminology graduates end up becoming security guard. Results revealed that the attraction of the Philippine National Police (PNP) as a job destination for graduates of Criminology stems from the better well-being perceptions for the agency. In particular, there are better opportunities for promotion and benefits at PNP than at the BFP and the BJMP and, likewise, for the number and frequency of recruitment in the agency. These positive well-being dimensions are reinforced by the fact that in terms of workload and work pressure, the three agencies have equally high ratings. In other words, for the same level of work and stress, the PNP offers better opportunities for the growth and development than the other two agencies
