Chemistry is a human endeavor that relies on basic human qualities like creativity, insights, reasoning, and skills. It depends on habits of the mind: skepticism, tolerance of ambiguity, openness to new ideas, intellectual honesty, curiosity, and communication. Young female students begin studying chemistry curiosity; however, when unconvinced, they become skeptical. Researches focused on gender studies have indicated that attitudes toward science education differ between males and females. A declining interest in chemistry and the under representation of females in the chemical science was fo...

The study examined the effects of rural and urban orientations on pupils’ performance on WISC-R (a standardised intelligence test). The study made use of an experimental method. The data were collected on a sample of 100 primary school pupils (50 rural and 50 urban). The participants were from grade 5 and had an average age of 10 years. The independent variable was the environment in which the pupil was raised. The dependant variable was the performance of the pupils on the WISC-R intelligence test. The control group of the study was the rural pupils, whilst the urban based pupils were the exp...

With over thirty-five years in the making, hip-hop has grown and developed into a global phenomenon. Despite its global expansion from the Bronx, New York, in the 1970s, the hip-hop arts confront criticism, both aesthetically and culturally. Repeatedly criticized as an art that glorifies misogyny, pimping, prostitution, objectification of women, crime, homophobia, and other forms of discrimination, scholars denounce the hip-hop arts as ignorant, offensive garbage, devoid of any aesthetics and culture. However, this is a limited, one-sided view of the hip-hop arts and culture. From local urban ...

Using a qualitative ethnographic approach, this research investigated the situation of the Tsotsil language spoken in Chenalhó, Chiapas, Mexico, by focusing on the implementation of a Spanish-Tsotsil bilingual elementary school. It was possible to discover that the Tsotsil language is still alive and that most parents who participated in this research transmit it to their children. However, there are students who prefer Spanish instead of their native language Tsotsil, due to the negative attitudes they have towards it such as “it is the language of old fashioned people while Spanish is the la...

The aim of this dissertation research is to develop an understanding of how components of the organizational structure, leadership structures at the top level and resource allocation decisions may affect corporate reputation as defined by the reputation quotient(RQ),and which aspects of running a company top management should keep an eye on in order to maximize the reputation of their company? Based on a literature review on the topic of corporate reputation and governance, which comprises the first part of the dissertation, a positivistic, deductive approach was chosen and a self-adminis...

This research is dedicated to two main problems in finding shortest paths in the graphs. The first problem is to find shortest paths from an origin to all other vertices in non-negatively weighted graph. The second problem is the same, except it is allowed that some edges are negative. This is a more difficult problem that can be solved by relatively complicated algorithms. We attack the first problem by introducing a new data structure - Relaxed Heaps that implements efficiently two main operations critical for the improvement of Dijkstra's shortest path algorithm. R²heaps with suspended re...

This thesis describes a telemedicine approach to a computer-aided healthcare system. NEMESIS is the Spanish acronym of New Electrocardiographic Medical Station with Information Systems. The application is a comprehensive tool set, structured around a main navigation bar, which leads to every sub-application. Those sub-applications are window based, user-friendly tools, comprising specific health tools for physicians, telemedicine/telematics tools and general-purpose tools. The whole application is built in a highly structured and modular way, which allows adding or excluding mod...

The high degree of heterogeneity of textile composites was found to be the primary problem in analysis and testing. A concept was developed based on a description of the local variation of the material stiffness matrix using a spline interpolation. The role of this stiffness function is to facilitate the calculation of the material stiffness matrix at any given position or for arbitrary domains in the form of finite elements.Based on this approach, two different methods were developed. In the first method the average material stiffness matrix is calculated for a finite element and subsequently...

For my thesis I studied government A-76 studies and outsourcing in general. Specifically my goal was to determine the efficiency resulting from these often timely and intensive studies. To do this I first looked at several functional areas to include Army Depot level maintenance, Training and Professional Development, family housing or the Residential Communities Initiative, and the Logistics Civil Augmentation program. I then looked at specific installation A-76 studies for three installations, FT Belvoir, Virginia, Aberdeen Proving Grounds, Maryland, and Carlisle Barracks, Pennsylvania. My i...

There is no doubt that electronic marketing has contributed positively in the life of modern societies, mainly the consuming societies. It allowed purchasing of materials cheaply without any limit, and without any restrictions. It also gave the chance to make a free selection and comparison between the prices of goods at the electronic department stores throughout the Internet. All such facilities are given to the consumers in a very short time without causing them to leave their office or home. In addition, the Electronic Marketing has exterminated the monopoly of goods and materials, all suc...
