Determinants of project success

The interactions of numerous project characteristics, with particular reference to project performance, were studied. Determinants of success are identified along with the accompanying implications for client organization, parent organization, project organization, and future research. Variables are selected which are found to have the greatest impact on project outcome, and the methodology and analytic techniques to be employed in identification of those variables are discussed

A conceptual model for megaprogramming

Megaprogramming is component-based software engineering and life-cycle management. Magaprogramming and its relationship to other research initiatives (common prototyping system/common prototyping language, domain specific software architectures, and software understanding) are analyzed. The desirable attributes of megaprogramming software components are identified and a software development model and resulting prototype megaprogramming system (library interconnection language extended by annotated Ada) are described

International Relative Prices and Civil Wars in Sub-Saharan Africa. Theory and Evidence over the period (1995-2006)

This paper presents first a theoretical model of conflict between two agents characterized by a two-sector economy. In a contested sector two agents struggle to appropriate the maximum possible fraction of a contestable output. In an uncontested sector, they hold secure property rights over the production of some goods. Agents split their resource endowment between ‘butter’, ‘guns’ and ‘ice-cream’. Eventually, tradable goods made of butter and ice-cream produced by conflicting parties are both sold to the Rest of the world. Therefore, the opportunity cost of conflict depends also on relative profitability of contested and uncontested production. In particular, productivity of uncontested production and profitability of contested sectors are countervailing forces. The empirical section focused on a panel of Sub-Saharan African countries for the period 1995-2006. Results are not fully conclusive. However, there is robust evidence that prices of manufactures (interpreted as the uncontested ice-cream) are negatively associated with the likelihood of a civil war. Eventually, international price of manufactures is also associated with a higher GDP per capita growth rate. The concluding remark seems to be that an increase in world prices of manufactures would make civil wars less likely.Theoretical model of conflict, Civil war, resource curse, butter guns and ice-cream, structure of the economy, commodity prices, MUV, panel probit analysis

Gender differences in cooperative environments? Evidence from the U.S. Congress

This paper uses data on bill sponsorship and cosponsorship in the U.S. House of Representatives to estimate gender differences in cooperative behavior. We employ a number of econometric methodologies to address the potential selection of female representatives into electoral districts with distinct preferences for cooperativeness, including regression discontinuity and matching. After accounting for selection, we find that among Democrats there is no significant gender gap in the number of cosponsors recruited, but women-sponsored bills tend to have fewer cosponsors from the opposite party. On the other hand, we find robust evidence that Republican women recruit more cosponsors and attract more bipartisan support on the bills that they sponsor. This is particularly true on bills that address issues more relevant for women, over which female Republicans have possibly preferences that are closer to those of Democrats. We interpret these results as evidence that cooperation is mostly driven by a commonality of interest, rather than gender per se

Electoral Rules, Forms of Government, and Political Budget Cycles in Transition Countries

Recent studies have suggested the existence of election-year economics in fiscal policy in transition countries. This study asks whether such electoral cycles in aggregate measures (overall expenditures, revenues and balance) and spending composition (broad vs. targeted outlays) differ among countries with different political systems. This question is motivated by a sharp division between majoritarianpresidential systems in Central Asia and Eastern Europe, and proportional-parliamentary systems in the Baltics, Central and Southeastern Europe. Further, in the absence of context-sensitive theories, the paper asks whether observed outcomes in the transition process conform to the theoretical priors developed for conditions in stable democracies. Finally, the paper attempts to normatively establish whether either of the alternative combinations yields more optimal policy outcomes. The results suggest that the differences indeed exist, primarily on the revenue side and in the composition of expenditures. These results differ markedly from those for stable democracies, especially in the case of composition of spending. Normatively, presidentialism yields suboptimal outcomes in comparison to parliamentarianism, likely due to inefficient system of constitutionally intended checks and balances..Political budget cycles, Transition countries, Electoral rules, Forms of government, Checks and balances

Refining the Material Substance: Aristotle's Program in Metaphysics H1-5

In Met. Z17, Aristotle makes a fresh start (1041a6) in his discussion on substance. Accordingly, the substantial form is principle and cause (1041a6-10, 1041b8), whereas the matter is element (1041b31) of material substances. Besides, Aristotle assumes (probably without justifying in Z17) that material substances are unified wholes (1041b11-12). These are two main theses in Z17 whose apparent absence in the summary of H1 (1042a3-23) has raised doubts among commentators as to the very project of H a book commonly held to be a bunch of notes on Z. Regarding H?s positive results, commentators mostly focus on the introduction of the modal vocabulary of potentiality and actuality into which Z?s distinction between matter and form is translated. So they find book?s H proper contribution only in H6?s solution to the problem of unity (1045a23-25, 1045b18-19). As a consequence of this reading, H1-5 remain overshadowed by H6, and therefore they are often neglected. Contrarily to this still predominant trend towards not taking H1-5 on their own, I will here try to show that these chapters develop a program, in which H6?s conclusion is properly prepared. Stations of this program are H2-3, where Aristotle justifies the priority of form, and then H4-5, where he does the same for the unity of material compounds. So, I aim to show that H1-5 are a centerpiece in the completion and fulfilment of Z17?s theory of material substance.Fil: Mie, Fabian Gustavo. Universidad Nacional del Litoral.
