Psychological impact of Social Networking Sites
Get PDFThe preponderance of social networking sites such as Facebook, Youtube and others, have altered the way in which people interact socially in the real world. In fact, much more can be said about the impact of these modern technologies on the basic structure of human personality: the id, ego, and super-ego. The paper proposes a psychosological theory that modifies Sigmund Freud’s (1923) basic relationships and interactions of the id, ego and super-ego in his Psycho-analytic Theory. It is claimed that an individual’s engagement with virtual reality (social networking) portends a segregation of the super-ego from the id and ego. In a virtual world, social interactions are not constrained by societal norms and standards (super-ego) so that the tendency is for the id (instincts and drives) to merge with the ego (what is real) and they become indistinguishable. The sociological implications of this theory are also explored in this paper
Contemporary nursing care based on Watson’s theory
Get PDFThe study utilized a descriptive, correlational design. A purposive criterion sampling was employed using a paper and pen questionnaire based on the theory by Jean Watson on her ten carative factors. The study attempted to answer the level of care rendered by the nurses towards their patients and if there was a noteworthy association among the level of care rendered by the nurses and the patient’s demographic profile (age and gender) and nurse’s profile (gender; and hospital classification). As to the Level of Care Rendered by the Nurses Towards their Patients, the computed mean reveal an interpretation of very good. Patient’s profile and the level of care did not yield a significant relationship. There was a noteworthy association among the level of care and nurse’s gender (p = 0.012) on the area where the nurse practices loving kindness and composure inside framework of caring awareness towards patients. The level of care and the hospital classification findings revealed significant relationship on two items (p = 0.020 and .048). The level of care in terms of the nurse assisting with basic needs, with an intentional caring consciousness, administering “human care essentials”, which potentiate alignment of mind, body, spirit, wholeness, and unity of being in all aspects of care; tending to both the embodied spirit and evolving spiritual emergence are better experienced by patients in government hospitals. Based on the findings Cebuano nurses were very good in their nursing care towards their patients
Aspects of climate change induced by human activities
Get PDFSome scientists believe that global warming and the consequent climate change are inevitable results of slight deviations of the earth’s movement around its axis, a greater majority of scientists stipulate that a greater bulk of the reason for global warming and climate change is accounted for by human activities that destroy the natural environment. The present study looks into the chain of events that lead to natural disasters with specific focus on quantifying the human contribution to these catastrophes. The centroid regression approach identifies the categories of countries that contribute most to the world’s CO2 emissions and determines the relationship among natural resource depletion (% forest area) and CO2 emission and forest land area. The fitted curve states that the CO2 emissions increases as the square of the fossil fuel usage by the countries so that those nations, particularly those belonging to the high and very high HDI which are highly developed, contribute tremendously to the level of CO2 emissions across the globe. The impact of human exploitative activities on the accelerated CO2 accumulation in the atmosphere led to natural disasters spawned by rising global temperatures increasing natural disaster mortality
Fractal similarity index for forensic handwriting analysis
Get PDFThe use of fractal analysis is recommended to place handwriting analysis within the purview of science and scientific methods. The current practice of subjecting a questioned document to a handwriting expert’s eye borders on art and is replete with subjectivity. A similarity index based on the fractal dimension of a handwritten document is proposed to augment the current practice. A random sample of ten(10) respondents, five(5) male and five(5) female, were asked to copy ten(10) paragraphs of the same lengths by hand. The first paragraphs for each respondent was used as the specimen document while the remaining nine (9) paragraphs were utilized to test and validate the proposed fractal procedure. Results revealed that the similarity index identified authorship as well as genuineness (of signatures) with 99% accurac
Characterization of Mathematics tests’ level of difficulty and discrimination through roughness analysis
Get PDFThis paper is an exploratory study that deals with fractal dimensions in assessment and evaluation. Specifically, the study sought to determine how the tests characteristics: test difficulty and discrimination, may be quantified through knowledge of the fractal dimensions of the tests. As a by-product of the analysis, we may be able to identify which among the subjects in mathematics (from first year to fourth year) is found most difficult through analyzing and evaluating the ruggedness and irregularities of students’ performance. The researcher made use of fractal statistics and segmentation to determine the test difficulty and the mathematical capability of the students. Results reveal that test fractal dimensions can be used as surrogate measures of both test difficulty and test discrimination indices. Both traditional test characteristics monotonically increase and decrease with increasing or decreasing fractal dimensions. High fractal dimensions indicate huge variances in student performance which are tell-tale symptoms of uneven understanding of mathematical concepts
Sensitivity of humanity on valuing life
Get PDFThis study aims to discover the intensity of values appeciation. Data are mined using internet databases and subjected to cluster analysis. Around 79 countries were sampled to determine values to the: (1) family; (2) environment; (3) work; (4) home finances; (5) morale; and (6) national identity. Religion was also considered for the analysis to determine direct or indirect relationship with the other variables. The study identified 3 models in valuing life: (1) Ideal model (person-oriented); (2) Transactional model (material-oriented/economic-oriented); and (3) Passing and Asocial model (egocentric). Further, it reveals that the family has the major role in cultivating values. It is the milieu that stands as the individual’s first community, school and government. This is then translated to other human transactions
Purchasing and control strategies
Get PDFMedium-scale enterprises have developed overtime and have performed a critical role in driving a country’s industrial transformation in most developed countries. A hardware establishment is a superb example of medium-scale endeavor. In the Philippines, particularly in Cebu City, the identified economic potentials of medium-scale enterprises slowly relegated due to challenges and constraints of a highly competitive oligopolistic market, product and demand variability including variances in purchasing strategies and internal control systems of most industries. One representation is Alliance Hardware, Inc. which desires to attain a 100% service level but the management has no idea as to the cost implications of the possible actions that they will take. This study intends to develop an appropriate inventory system so as to increase the company’s service level that will specifically cater to their needs as well as the needs of their customers. The research looks into establishing a standard reorder point and order quantity that will help the medium-scale hardware enterprises minimize inventory costs while minimizing or eliminating the presence of stock outs. Specifically, the study aims to optimize the service level using inventory management principles taking into account the company’s purchasing and internal control strategies in an oligopolistic environment. I analyzed all the data gathered and interpreted using industrial, operations and project management tools. Also, concepts such as reorder point, economic order quantity, safety stocks and service level were used. The computed standard reorder point and economic order quantity served as the basis for comparison in determining whether there is an improvement in the actual service level of Alliance Hardware, Inc. which serves as a good representation of a medium-scale venture. Finally, I then formulated solutions and alternatives that would help the company improve their inventory operations, thus, an increase in their level of customer service. Using the standard economic order quantity and reorder point that I have computed based on the data gathered would imply yearly savings of Php 838,355.10 for the company which is an enormous cutback on expenses especially for medium-scale enterprises in general
Geographic Crime Information Reporting System
Get PDFThe primary goal of this study is to successfully develop a Geographic Crime Information Reporting System at a station in Mandaue City, an electronic blotter that uses Geographical Information System (GIS) in recording crime information. The “Geographic Crime Information Reporting System” contains a Geo Spatial Crime Visualization module that loads and displays the maps from shape files. The Crime Management Module to assign coordinates in the map given by the user to be stored in a Database. The Geographic Crime Information Analyzer analyzes the data and creates a report which is a list of possible suspects. The system is then evaluated by randomly selected Philippine National Police Officers (PNP Officer) and Philippine National Police Information Technology personnel (PNP IT Personnel) of Mandaue City. The Results show that 75% of the respondents are familiar with the Electronic-blotter (E-Blotter), with only 26.7% of them who are currently using it. 85% are familiar with maps and pins, with 64.7% of them who are currently using it. The PNP Officers evaluated the usefulness of the E-blotter with a mean rating of 3.25, which is interpreted as Moderately Acceptable. And to the usefulness of the maps and pins with a mean rating of 3.82, which is interpreted as Very acceptable. The Response clearly showed that the proposed system is useful. The PNP officers evaluated the system interfaces ease of understanding as 3.95, which is interpreted as very acceptable. The system’s provision of time efficient decision making was rated 3.9, which is interpreted as very acceptable. The system’s implementation of the theories was rated 3.85, which is interpreted as very acceptable. The system’s accuracy of results was rated 3.75, which is interpreted as very acceptable. The PNP officers evaluated the systems importance (include all results) with an overall rating of 3.8625 which is interpreted as very acceptable. The PNP IT personnel evaluated the system with an overall rating of 4.515 on a 5-point rating system which is interpreted as completely acceptable.

Traffic light management system using image processing
Get PDFTraffic control is important. Traffic congestion creates many problems in our everyday lives. Travel time increases which lead to waste of time and fuel. A system that can manage traffic through the efficient use of traffic lights by applying an algorithm to control the time for the signals of a traffic light would be beneficial. A system was developed by using a modified waterfall model. Data from the City Traffic Operations Management (CITOM) were utilized. Images were taken using a digital camera from the GMT building and the Montesclaros Building to acquire snapshots of actual traffic zones. An image processing module was developed after reading on image processing and edge detection. A traffic density module was created to determine the density for each phase. A traffic management module was created by taking the phase densities into consideration. In the system, the snapshots were analyzed. After analysis, the system applied an algorithm which adjusts the time of a certain intersection based from its density. The system also stores analyzed data into a database. CITOM personnel gave the system an overall rating of 4.260 on a 5-point rating system, which is interpreted as completely acceptable. Meanwhile, motorists rated the system’s importance, and 100% of them wanted it to be implemented
Implementation of the National Competency-Based Teacher Standards in the UV-College of Teacher Education
Get PDFThe study determined whether the student teachers have achieved the expected competencies required by the new curriculum in teacher education. The National Competency-Based Teacher Standards (NCBTS) explicitly lay down the set of behaviors, attitude and skills that each student teacher must possess. Using a researcher-made questionnaire, this study assessed the competencies of the student teachers in comparison with the standard skills embodied in the NCBTS using a researcher-made questionnaire. All the 38 student-teachers who enrolled during the 1st semester of 2011 – 2012 and 22 mentors of the University of the Visayas Laboratory School- Main Campus were involved in the study. Both the student teachers and the mentors had an orientation before answering the questionnaires. Results are analyzed using descriptive statistics for the level of competency and Pearson coefficient to determine the significant relationship of competency level and student performance. The student teachers perceived themselves as highly competent as classroom teachers and this confirmed by the mentors. Mentors perceived the student teachers as very competent in almost all aspects of the seven NCBTS skills. They were best in professional growth and development and in social regard for learning. However, they lie low in community organizing or building linkages and understanding the diverse learning abilities of students. Likewise, though competent enough, the student teachers need to keep abreast with the recent trends in education. Student teaching performance was related to the students’ learning environment, suggesting that when mentors provide a conducive environment, assistance and modeling, the student teachers would learn the teaching skills and proper behavior of an efficient and effective teacher. The curriculum has also enhanced the students teaching skills, which means that the program was useful for student teachers
