Walled, gated, and guarded social clubs in Mexico City typically denote to the public a material and symbolic representation of exclusion and privilege. Many of these private communities have been home to affluent Mexicans for at least fifty years. In recent decades, however, it has become more common for the middle class to frequent these spaces and create their own social networks therein. Based on participant observation and interviews with...

Suicide, the endpoint of the continuum that begins with suicide ideation, is an important precursor of attempted suicides. The purpose of this study was to investigate sex differences in suicide ideation as well as the coping strategies used by university students. The convenience sample was drawn from first year psychology students at Fort Hare University (East London Campus). The Positive and Negative Suicidal Ideation Scale (PANSI), and The...

This book introduces a new optimization algorithm for simulation-based design of systems with multi-modal, nonlinear, black box objective functions. The algorithm extends the recently introduced adaptive multi-modal optimization by incorporating surrogate modeling features similar to response surface methods (RSM). The resulting optimization algorithm has reduced computational intensity and is therefore well-suited for optimization of expensiv...

Bullying can have enduring effects on boys, with a lasting impact of depressive and traumatic symptoms. Gay adolescent males are particularly susceptible to bullying, and may be targeted at a higher frequency than heterosexual boys. This heightens the experience of isolation and self-hatred that many gay adolescents report. However, not all individuals who are bullied develop depressive or traumatic symptoms. Those who received parental suppor...

The heuristic value of the political dichotomy Left and Right has been the subject of much debate since the end of the Cold War. In South Africa, the two terms are frequently used to describe political contestation within the ruling African National Congress (ANC)and the Tri-partite Alliance between the ANC, the South African Communist Party and the Congress of South African Trade Unions. However, what is behind the label 'Left''? Writing abou...

Ship breaking is a potential industry for Bangladesh. At present the position of Bangladesh is third in the world for ship breaking activities. This industry pays about 100 million to 130 million USD each year to the government. Bangladesh does not have iron as such has to depend on the scrapped iron and about 90% of iron materials come from this industry. Other items of the ship such as engines, generators, boilers, electrical items, furnitur...

This study attempts to explore women''s political participation in the militant political movement on the basis of agency and emancipation. The analysis is based on Nepal''s Maoist movement and women''s agency within this. While analyzing, this study also gives special attention to the relationships of agency, emancipation and violence. Many feminist writings in the west challenge the notion of agency and say that it is absent in patriarchal m...

Education is a fundamental human right. Attaining the right to equality of education is not only having equal opportunity to access and complete education, but also having equal opportunities to receive equal quality of education, which ensures opportunities for every pupil to maximize their educational potential. The current education system in Croatia produces barriers in achieving the right to equality education for the Roma children. It is...

Web-based educational systems are now becoming part of main stream education. As an essential component of the web based educational systems, the student model enables the system to provide individualised course contents and study guidance, and therefore to help the students with different backgrounds and knowledge levels to achieve their learning goals effectively on the web. A prototype student model was developed in this project for a web b...

Retailers face increasing cost pressures and shorter product life cycles which often results in products becoming obsolete within a few months after their introduction. Meeting ever-changing customer demand in retailing creates difficulties for the retailers in balancing the costs of dealing with excess inventory and out-of-stock situations. However, Postponement helps retailers by improving responsiveness and reducing inventory, transport, wa...

While adaptation and coping with climate variability and change have become key themes in current global climate discussions and policy initiatives, literature on coping as distinct from adaptation appears to be still limited, with literature making reference to adaptation broadly. In view of this, research was conducted in Zimbabwe and Zambia to build an understanding on farmers'' perceptions of risk, analyze impacts from climatic variability...

A sustainable construction develops the idea of low embodied energy, reduced greenhouse gas emission and water consumption, low operational and maintenance costs, durability, safety, adaptability and comfort. Some important aspects concerning building sustainability are presented in the book. In the first part, the concept of sustainable development and its position in the scientific world is discussed. The main aspects of three sustainability...

Galerkin Boundary Element Method(GBEM) is a powerful technique to solve partial differential equations. In this work the method is presented by solving the axisymmetric Laplace''s equation. Later the Grad-Shafranov Equation(GSE) is solved by means of this powerful technique. The GSE is a simplification of ideal MHD in two dimensions. The resulting equation is a nonlinear, elliptic partial differential equation. The GBEM is well suited for solv...

Collaborative thinking activity integrates phenomenon when small group (2-5 persons) solves the problem or task and makes the decisions together. Collaborative thinking activity is described as generation of individual and common new formations: goals, senses and motives. Basing on the analyses of the experimental studies the specific patterns of the functioning and development of individual and common new formations are shown. Conceptions of ...

Creativity is arguably the most important factor in achieving advertising success, making it a hot topic amongst marketing experts. However, it should be realised that even though considerable amount of research has been dedicated to the subject, there are still many unresolved questions mainly due to the abstract nature of the term. Many practitioners have attempted to invent a universal definition while questions such as how it could be meas...

There is a fundamental difference between running somthing as a business and running it in a businesslike manner." This statement acknowledges one of the underlying problems of a public sector reform process that drew heavily on business models and languages of business. The reform of the New Zealand state-funded science system included the creation of nine limited liability companies that were charged with doing science for the benefit of New...

Over the years, there have been postulations and arguments among yam growers and agricultural extension agents that yams grown with the application of chemical fertilizers are more prone to losses in storage than yams produced with organic manure. Similarly, others postulated that agrobotanical extracts or gibberellic acid storage treatments actually prolong shelf life of yam tubers, but have negative effects on the organoleptic quality of yam...
