This book characterizes the kinematic and chemical structures of disk-forming regions around low-mass protostellar sources and their interplay based on Atacama Large Millimeter/submillimeter Array (ALMA) observations. It describes the chemical evolution of molecules formed in an interstellar gas using the ALMA observations of 5 Sun-like protostars at a spatial resolution of a few tens au scale, which unveils the physical mechanism of star and planetary formation. The book reviews the author’s successful works, focusing on two key findings: (i) A drastic change in the chemical composition of the gas around the centrifugal barrier of the infalling-rotating envelopes, and (ii) the chemical composition in the disk-forming regions, which varies from source to source depending on the chemical characteristics of the parent molecular cloud. These findings are based on the fine characterization of physical structures based on careful kinematic analyses. An additional attraction is the inclusion of the skillful reviews of ALMA observatory and its observation and physical models to describe the observed gas structure.

This paper uses a life-cycle framework to document new stylized facts about the nexus between job polarization and earnings inequality. Using quarterly labor force data for the UK over the period 2000-2018, we find clear life-cycle profiles in the probability of being employed within each occupation type and wages earned therein. Cohort plots and econometric analysis suggest that labor market outcomes and prospects have gradually worsened for the young. These adverse trends are particularly significant for low-skill women: estimated cohort effects point to a fall in wages within each occupation as well as a lower propensity of being employed in abstract-task occupations. We also find evidence of general occupational downgrading in the UK, with more educated workers taking up fewer high-skill occupations than they did in the past. Our analysis informs the policy debate over appropriate measures needed to reduce skill mismatches and alleviate labor market transitions.

For African American men without a high school diploma, being in prison or jail is more common than being employed—a sobering reality that calls into question post-Civil Rights era social gains. Nearly 70 percent of young black men will be imprisoned at some point in their lives, and poor black men with low levels of education make up a disproportionate share of incarcerated Americans. In Invisible Men, sociologist Becky Pettit demonstrates another vexing fact of mass incarceration: most national surveys do not account for prison inmates, a fact that results in a misrepresentation of U.S. political, economic, and social conditions in general and black progress in particular. Invisible Men provides an eye-opening examination of how mass incarceration has concealed decades of racial inequality. Pettit marshals a wealth of evidence correlating the explosion in prison growth with the disappearance of millions of black men into the American penal system. She shows that, because prison inmates are not included in most survey data, statistics that seemed to indicate a narrowing black-white racial gap—on educational attainment, work force participation, and earnings—instead fail to capture persistent racial, economic, and social disadvantage among African Americans. Federal statistical agencies, including the U.S. Census Bureau, collect surprisingly little information about the incarcerated, and inmates are not included in household samples in national surveys. As a result, these men are invisible to most mainstream social institutions, lawmakers, and nearly all social science research that isn't directly related to crime or criminal justice. Since merely being counted poses such a challenge, inmates' lives—including their family background, the communities they come from, or what happens to them after incarceration—are even more rarely examined. And since correctional budgets provide primarily for housing and monitoring inmates, with little left over for job training or rehabilitation, a large population of young men are not only invisible to society while in prison but also ill-equipped to participate upon release. Invisible Men provides a vital reality check for social researchers, lawmakers, and anyone who cares about racial equality. The book shows that more than a half century after the first civil rights legislation, the dismal fact of mass incarceration inflicts widespread and enduring damage by undermining the fair allocation of public resources and political representation, by depriving the children of inmates of their parents' economic and emotional participation, and, ultimately, by concealing African American disadvantage from public view.

Data mining has become the fastest growing topic of interest in business programs in the past decade. This book is intended to describe the benefits of data mining in business, the process and typical business applications, the workings of basic data mining models, and demonstrate each with widely available free software. The book focuses on demonstrating common business data mining applications. It provides exposure to the data mining process, to include problem identification, data management, and available modeling tools. The book takes the approach of demonstrating typical business data sets with open source software. KNIME is a very easy-to-use tool, and is used as the primary means of demonstration. R is much more powerful and is a commercially viable data mining tool. We also demonstrate WEKA, which is a highly useful academic software, although it is difficult to manipulate test sets and new cases, making it problematic for commercial use.

This fascinating account of young women's lives challenges existing assumptions about working class life and womanhood in England between the end of the First World War and the beginning of the 1950s. While contemporaries commonly portrayed young women as pleasure-loving leisure consumers, this book argues that the world of work was in fact central to their life experiences. Social and economic history are woven together to examine the working, family, and social lives of the maids, factory workers, shop assistants, and clerks who made up the majority of England's young women. Selina Todd traces the complex interaction between class, gender, and locale that shaped young women's roles at work and home, indicating that paid work structured people's lives more profoundly than many social histories suggest. Rich autobiographical accounts show that, while poverty continued to constrain life choices, young women also made their own history. Far from being apathetic workers or pliant consumers, they forged new patterns of occupational and social mobility, were important breadwinners in working class homes, developed a distinct youth culture, and acted as workplace militants. In doing so they helped to shape twentieth-century society.
