The diversity of stellar death is revealed in the energy, velocity and geometry of the explosion debris ("ejecta''). Using multi-wavelength observations of gamma-ray burst (GRB) afterglows I show that GRBs, arising from the death of massive stars, are marked by relativistic, collimated ejecta ("jets'') with a wide range of opening angles. I further show that the jet opening angles are strongly correlated with the isotropic-equivalent kinetic energies, such that the true relativistic energy of GRBs is nearly standard, with a value of few times 10^51 erg. A geometry-independent analysis whic...

The purpose of this book was to describe the variables that contributed to the establishment of a charter school in an urban Arizona and rural California school district, noting the similarities and dissimilarities and disclosing the factors used to justify implementation of the Montessori theory of education. The secondary purpose of this book was to describe the guidelines for maintaining a charter school, the evaluation methods and factors used in the school’s unique experience with staff development. The two schools experienced many similarities when the same variables were applied to bot...

"This study is an early evaluation of the benefits of using the internet and information technology for Human Resources programs and practices by a sample of large public and private for profit and not for profit organizations. The respondents themselves were higher in transformational leadership. Additionally, those with higher transformational scores were more likely to use IT for Human Resources Management. The use of IT enhanced accessibility, timeliness, and HR decision making. We are likely to see in the years to come many more evaluated shifts of HR programs and practices from...

Students of organisation have used complexity theory in many different ways and for many different reasons. What characterises the writings of most ‘management thinkers’, however, is that the authors are primarily concerned with the question of “how to make this complexity thing work for us?” This study takes a rather different approach. Ideas and concepts of the science of complexity are borrowed to develop the idea that organisations live lives of their own – an idea that is very much at odds with the dominant view that understands organisations as tools that we use to realise certain goals....

The prospect for democracy in Africa is the central concern of this study. The factors that contribute to the existence of undemocratic or autocratic governments in most of Africa, therefore, become our major focus for evaluation.An analysis of the pre-colonial, colonial and postcolonial political history of Africa attribute autocracy in Africa to irreconcilable differences between the African traditional institutions and the imposed colonial political and economic systems. This socioeconomic and political disharmony, orchestrated by the colonial economics of exploitation, set the tone for neo...

The central focus of this study is to provide an improved basis for articulating the politics of transnational television and its potentials for improving relations among nations. In this context, the politics of transnational television means the decision-making process that determines the degree of freedom of the press tolerated by individual governments and how that could affect broadcasting mode and attitudes toward other nations.The motivation for this research stems from a conviction that the cultural imperialism perspective on the nature and modes of transnational television are erron...

(Complete work in Spanish) Remote sensing aerial spectral imaging was one of the first application areas where spectral imaging was used in order to identify and monitor the natural resources and covers on earth surface. Aerial spectral imaging is being developed with the aim of monitoring natural resources like coastal areas, forestry and extensive crops. The information contained in hyperspectral images allows the reconstruction of the energy curve radiated by the terrestrial surface throughout the electromagnetic spectrum. Hence, the characterization, identification and classification of th...

This study focused on factors that have positively influenced the model of economic success for commercial and thrift megabanks involved in merger and acquisition activities for the period 1990 - 1997, a period characterized by an unprecedented flurry of merger and acquisition activities among megabanks in the United States. This study identified and measured key independent variables for identifiable mergers and acquisitions among megabanks and tested the extent to which, such independent variables influenced abnormal returns for underlying equities traded in capital markets. This study also ...

Since its inception in the early nineteenth century, the basic tenet of dispensationalism (a school of Protestant theology which holds that God deals with humankind in different ways in different periods of time called dispensations) has been that the church and Israel are two sharply distinct peoples of God. The distinction is theological in nature; specifically, anthropological (pertaining to humanity), soteriological (pertaining to salvation), and eschatological (pertaining to last things). The tenet of theological distinctiveness has always been the cornerstone for the dispensationalist's ...

This dissertation seeks to establish that there is a renaissance of Thomistic Philosophy in the Post-Conciliar Catholic Church, specifically a reawakening of Scholasticism, as evidenced by Pope John Paul II in his encyclical Veritatis Splendor. The Second Vatican Council (1962-1965) ushered in a new era for the Roman Catholic religion prompted by the desire of Pope John XXIII to have the 2,000 year old institution catch up with the modern world and address current problems as well as present the ancient faith in contemporary ways. Prior to Vatican II, there was a monolithic way to explain fait...
