Hispanics account for more than half the population growth in the United States over the last decade. With this surge has come a dramatic spike in the number of Hispanic-owned businesses. Hispanic Entrepreneurs in the 2000s is a pioneering study of this nascent demographic. Drawing on rich quantitative data, authors Alberto Dávila and Marie T. Mora examine key economic issues facing Hispanic entrepreneurs, such as access to financial capital and the adoption and vitality of digital technology. They analyze the varying effects that these factors have on subsets of the Hispanic community, such as Mexican Americans, Puerto Ricans, Cubans, and Salvadorans, while considering gender and immigrant status. This account highlights key policies to drive the success of Hispanic entrepreneurs, while drawing out strategies that entrepreneurs can use in order to cultivate their businesses. Far-reaching and nuanced, Hispanic Entrepreneurs in the 2000s is an important study of a population that is quickly becoming a vital component of American job creation.
At the landmark centennial anniversary of the 1917 Jones-Shafroth Act, which granted Puerto Ricans U.S. citizenship, the island confronts an unfolding humanitarian crisis initially triggered by an acute economic crisis surging since 2006. Analyzing large datasets such as the American Community Survey and the Puerto Rican Community Survey, this book represents the first comprehensive analysis of the socioeconomic and demographic consequences of “La Crisis Boricua” for Puerto Ricans on the island and mainland, including massive net outmigration from the island on a scale not seen for sixty years; a shrinking and rapidly aging population; a shut-down of high-tech industries; a significant loss in public and private sector jobs; a deteriorating infrastructure; higher sales taxes than any of the states; $74 billion in public debt plus another $49 billion in unfunded pension obligations; and defaults on payments to bondholders. This book also discusses how the socioeconomic and demographic outcomes differ among stateside Puerto Ricans, including recent migrants, in traditional settlement areas such as New York versus those in newer settlement areas such as Florida and Texas. Florida is now home to 1.1 million Puerto Ricans (essentially the same number as those living in New York) and received a full third of the migrants from the island to mainland during this time. Scholars interested in the transition of migrants into their receiving communities (regardless of the Puerto Rican case) will also find this book to be of interest, particularly with respect to the comparative analyses on earnings, the likelihood of being impoverished, and self-employment.
This book presents a new concurrent logic programming language called Conclog and a methodology for programming in it. Conclog was designed bytaking the ideal features of logic programming as reference, rather than by concentrating directly on operational tricks to ensure efficiency. This leads to quite easy declarative programming. Concern for soundness and completeness ensures that multi-directional and multi-solution correct procedures can be coded quite straightforwardly. Assuming suitable hypotheses on their uses, they can be transformed into very efficient versions thanks to the introduction of appropriate control information. Correctness-preserving properties are given for that purpose. The designof Conclog involves three steps. First, a sound and complete parallel execution model of Horn clause programs is proposed which reduces subgoals of conjunctions independently and uses a calculus for reconciling inconsistent bindings. Second, this is extended to handle negation as completely as possible. Third, a minimal and reasonably complete set of extra-logical features are defined for optimization and practical purposes. The second part of the book presents a methodology for constructing Conclog in a rigorous way. This covers the entire programming process, from informal specifications via logic descriptions to efficient programs. The methodology can be adapted to other languages.
