This article investigates the determinants of subsidiaries' profitability using a unique dataset of more than 23,000 listed and unlisted subsidiaries worldwide over the period 1994-2005. We find that profitable parent companies are able to transfer some of the intangible assets that make them profitable to their subsidiaries. Our results indicate that good institutions (measured by the Worldwide Governance Indicators) are associated with better performance for companies' subsidiaries. When we categorize countries in terms of the origins of their legal systems, we also find that this dimension of institutional quality is generally associated with better performance. Controlling for both legal origins and country governance institutions, we find that both sets of institutions are significantly related to subsidiaries' performance, and that there is an overlap in their explanatory power.

Chapter 1 develops a model of parallel trading of corporate securities (shares, bonds) and derivatives in which a large trader can sometimes profitably acquire securities and the corporate control rights inherent therein for the sole purpose of reducing the corporation's value and gaining on a net short position in the corporation created through off-setting derivatives. At other times, the large trader profitably takes a net long position in the corporation and exercises its control rights to maximize the corporation's value. This strategy is profitable if and because other market participants cannot observe the large trader's orders and hence cannot predict how the control rights will be exercised. In effect, the large trader is benefitting from trading on private information about payoff uncertainty that the large trader itself creates. This problem is most likely to manifest in transactions that give blocking powers to small minorities, particularly out-of-bankruptcy restructurings and freezeouts, and is bound to become more severe when derivatives trade on an exchange rather than over-the-counter. Chapter 2 investigates in parallel the cross-country determinants of crime and punishment in the largest possible sample of countries with data on homicides, victimization by common crimes (ICVS), incarceration rates, and the death penalty. While models with a small number of plausible covariates predict much of the variation of homicide and incarceration rates between major developed countries, they predict only one seventh of the actual US incarceration rate. Chapter 3 probes into the pervasive correlations between legal origins, modern regulation, and economic outcomes around the world. Where legal origin is exogenous, it is almost perfectly correlated with another set of potentially relevant background variables: the colonial policies of the European powers that spread the "origin" legal systems through the world. The chapter attempts to disentangle these factors by exploiting the imperfect overlap of colonizer and legal origin, and looking at possible channels, such as the structure of the legal system, through which these factors might influence contemporary economic outcomes. It find strong evidence in favor of non-legal colonial explanations for economic growth. For other dependent variables, the results are mixed. / Economics

Because the ancestry of extant amphibians remains highly controversial, under traditional perspectives, amphibians and amniotes often are distinguished by differences in developmental mode rather than their evolutionary relationships. Resolution of relationships is important, however, because phylogeny affects interpretations of biology, including the evolution of development. To address those issues, I documented the growth and development of two extinct lepospondyls, Microbrachis pelikani and Hyloplesion longicostatum, and compared the patterns in those taxa to data from other tetrapods. I quantified allometry in the skeleton using both measurement-based and geometric morphometric analyses. I applied Ontogenetic Sequence Analysis (OSA), a size-independent method, to the reconstruction of ossification sequences based on fossils. I also documented skeletal morphogenesis and used Parsimov Analysis and Parsimov-based Genetic Inference of ossification sequence data to evaluate the three hypotheses of extant amphibian ancestry, the Lepospondyl (LH), Temnospondyl (TH), and Polyphyletic (PH) hypotheses. Skeletal growth in Microbrachis pelikani and Hyloplesion longicostatum is primarily isometric. Comparisons with data from other Paleozoic taxa suggest that isometry was the ancestral pattern of growth in tetrapods. All regression analyses had a linear fit indicating lack of an abrupt metamorphosis. Absence of metamorphosis is also supported by the possession of lateral lines in both taxa throughout ontogeny, and Microbrachis pelikani additionally retained gills. However, ossification of the skeleton was completed at small body size. The greatest resolution in ossification sequence reconstruction was achieved with OSA, but results from all reconstruction methods indicated advanced ossification of the pubis and delayed ossification of the scapula in the lepospondyls. In terms of total number of sequence shifts optimized across each hypothesis of amphibian relationships, the TH had the shortest tree length. However, the values for the three hypotheses did not differ significantly, demonstrating that none was supported strongly. Based on my synthesis of new developmental data, I propose that Microbrachis pelikani and Hyloplesion longicostatum expressed a mosaic pattern of skeletal development. That pattern included a gradual transition to an adult morphology, and a lack of an amphibian-like metamorphosis. A similar pattern is common to most early tetrapods and Eusthenopteron, supporting the hypothesis that metamorphosis is not ancestral for Tetrapoda. / text

A high degree of physical functioning is necessary for independently performing the numerous routine and valued tasks of daily life. Poor functioning not only hinders independent living, it can lower the quality of life, impede full social participation, and elevate the risk of death. However, not all adults are at equal risk of poor functioning: women experience worse functioning and live a greater number of years functionally impaired compared with men. Studies of this gap have focused on inequities in adult circumstances, such as socioeconomic status, but have generally fallen short of fully accounting for it. Recasting this research within a life-course, epidemiological framework points to the potential role of early-life circumstances. Early-life circumstances may impart a biological imprint, and they may also launch long-term trajectories of social circumstances, that could differentially shape functioning for men and women. Thus, this dissertation examines the life course origins of the gender gap in functioning and active life expectancy among older U.S. adults using two nationally-representative datasets: the National Survey of Midlife Development in the United States and the Health and Retirement Study. In sum, the findings reveal that: (a) a host of early-life circumstances, such as parents’ education levels, leave an indelible stamp on functional ability and active life expectancy for women and men, irrespective of adult circumstances, (b) while some early-life adversities, such as extreme poverty, were marginally more consequential for women’s than men’s functioning, they appear to be primarily more consequential for precipitating metabolic conditions such as diabetes and obesity rather than directly impacting functioning, (c) explanations of the gap must incorporate endogenous biological differences between men and women; explanations that focus exclusively on socially-structured inequities are insufficient, and (d) exposures to socioeconomic resources accumulate across the life course to shape functioning differently for men than women; particularly between white men, who enjoy better functioning with higher educational attainment irrespective of early-life socioeconomic exposures, and white women whose functioning gains plateau if they experienced early-life socioeconomic adversities. Overall, the results underscore the importance of a life course perspective in explicating gender disparities in functioning, longevity, and active life expectancy. / text

Despite the association of the first pottery with food production and sedentism, case studies show hunter gatherers with different degrees of sedentism commonly adopted ceramics. Monagrillo ware (∼ 4500-3200 BP), central Panama, early in Central America, was made by egalitarian slash and burn farmers, cultivating domesticated seed and root crops. People occupied inland rockshelters and coastal shell middens. Their degree of sedentism is debated. It is unclear whether they were sedentary both in the inland and the coast exchanging resources or whether inland people visited the coast during dry periods. Their pottery functions are not well understood. I provenanced and studied production processes and diagenesis of Monagrillo pottery combining life history approach and archaeometric methods. I assessed the degree of sedentism of people and inferred vessel functions producers expected. I studied diagenesis because it probably affects analytical results. My study showed that pottery was produced and used in the foothills and on the coast, possibly, in the plains, of the seasonally dry Pacific side of Panama. This suggested that people were sedentary in areas surrounding Parita Bay. Vessels from the Pacific foothills were transported to perennially wet Caribbean slopes; where production was difficult due to precipitation. According to technical choices made, I infer that potters in the Pacific foothills opted for useful and dependable designs, for cooking. Transportability and resistance to weathering were also important. Pacific coastal producers may have chosen designs for cooking-related attributes, but not transportation. Finally, a Pacific plains intermediate site had a high proportion of vessels from both the Pacific foothills and the coast and had a high proportion of decorated sherds. This site may have had special functions such as for meeting, feasting, and exchange. All producers shared manufacturing techniques indicating relatedness. Sherds excavated from the Caribbean zone and the Pacific coast had different diagenetic patterns suggesting climatic differences; this identification helped source pottery. My work contributes to knowledge about pottery origins and degrees of sedentism, technical choices made to reach functional needs, and climatic impact on production and post-depositional changes.

My dissertation project utilizes a theoretical perspective derived from historical ecology to explore the trajectory in prehistoric subsistence that began with the initial colonization of the region and eventually led to the domestication of indigenous plants, such as goosefoot and maygrass, roughly 5,000 calendar years ago. Because a major handicap for exploring prehistoric subsistence in eastern North America is the rarity of sites with preserved flora and fauna, I apply formal models derived from behavioral ecology to stone tool assemblages and archaeological site distributions to evaluate models that have been proposed for the emergence of domesticated plants. Based on my results, I argue that the origins of plant domestication came about within the context of a boom/bust cycle that has its roots in the Late Pleistocene and culminated in the Mid-Holocene. More specifically, warming climate caused a significant peak in the availability of shellfish, oak, hickory, and deer, which generated a "tipping point" during the Middle Archaic period where hunter-gatherer groups narrowed their focus on these resources. After this "boom" ended, some groups shifted to other plant resources that they could intensively exploit in the same manner as oak and hickory, which included the suite of plants that were subsequently domesticated. This is likely due the combined effects of increasing population and declining returns from hunting, which is evident in my analysis of biface technological organization and site distributions from the lower Tennessee and Duck River Valleys. Consequently, these conclusions are an alternative to Smith's (2011) assertion that plant domestication in eastern North America came about as a result of gradual niche construction with no evidence for resource imbalance or population packing.

My dissertation focuses on a relatively new field of study: the region immediately around galaxies known as the circumgalactic medium (CGM). The CGM holds vast quantities of mass and metals, yet its connection to galaxies is not well understood. My work uses cosmological hydrodynamic simulations and comparisons to data from Hubble's Cosmic Origins Spectrograph (COS) to understand the CGM's connection to galaxy evolution, gas accretion, outflows, star formation, and baryon cycling. This includes studies of the CGM's extent and physical conditions; the cause and nature of outflows; gas dynamics, including the first comprehensive study of tracers of inflowing and outflowing gas at low redshift (z=0.25); and direct comparison of theoretical results to observational data. Chapter 1 introduces my research and show its connection to galaxy evolution. Chapter 2 investigates hydrogen and metal line absorption around low-redshift galaxies in cosmological hydrodynamic simulations. This chapter studies different models for stellar outflows, physical conditions, and dependencies on halo mass. Chapter 3 examines the flow of gas into, out of, and around galaxies using a novel particle tracking technique. This chapter examines the baryon cycle in detail for our preferred model of stellar outflows. Chapter 4 compares our model results, including two separate prescriptions for outflows, with data from COS. We contrast these wind models, showing how they cycle baryons differently, and show degeneracies in observational diagnostics. In Chapter 5, I summarize and discuss plans for future research in this field, and how it can be more fully leveraged to understand galaxy evolution.

This dissertation locates the origins of the modern conservative movement in the intellectual history of the 1930s and 1940s. I argue that it was during the years of the Great Depression, when laissez-faire capitalism was most discredited, that a group of conservative academics and intellectuals began to lay the foundations for its postwar resurgence. Angered by the New Deal, those intellectual activists honed their free market ideology and began to develop a network through which to distribute it. As a result, they began to lay the intellectual and institutional foundation for the conservative movement. This dissertation recovers a number of narratives that reveal the rudimentary makings of a movement. It was during the 1930s and 1940s that economist Henry Simons worked to turn the University of Chicago's economics department into a bastion of free market sentiment; Leonard Read, after a decade of free market advocacy, created the first libertarian think tank, the Foundation for Economic Education, in 1946; legal scholar Roscoe Pound, worried by the spread of legal realism in the academy and growth of government in Washington, dramatically moved to the political right to make common cause with conservatives; Albert Jay Nock, his protégé Frank Chodorov and Felix Morley created a network of conservative writers and publications that paved the way for William F. Buckley's National Review ; and writers such as Rose Wilder Lane and Isabel Paterson made the case for laissez-faire in the pages of popular publications such as the Saturday Evening Post and the New York Herald Tribune . Historians have generally attributed the rise of the modern right to the conservative political mobilization in response to the civil rights movement, campus agitation of the 1960s, and the campaign for women's rights. As a result, historians tend to view the modern conservative movement as a distinctly postwar social and political phenomenon. This dissertation enriches that account by revealing the ties the modern conservative movement has to the years of the Great Depression and the debate over the government's role in the economy.

1984’s Operation Blue Star, an Indian Army maneuver to rid the Sikh Golden Temple of militants, shocked the world. Bullet holes riddled the temple’s façade in the operation’s aftermath, and the global Sikh community was outraged at the desecration of the site. How did the political conflict in Punjab escalate to this point? What were the factors behind the Sikh militant movement, and how did the militants rationalize their activities, considered by some as rampant terrorism? This thesis examines the circumstances surrounding the rise to arms of the Punjabi Sikh militants and the religious influences of their movement. Identifying how themes of the Sikh past, particularly those of communal identity, martyrdom, and martial tradition, were repurposed and employed by militant Sikhs to ground their violence in Sikh tradition and practice, the thesis finds that leaders of the movement, like Sant Bhindranwale, created rhetorical bridges to the Sikh past and embedded in the community a sense of participating in a greater, cosmic war. There exists a tendency among scholars to overlook the religious elements of the movement in order to assign political, economic or sociological roots to the conflict, but religion was a primary factor in the conflict, as demonstrated through the words and actions of the militants themselves. This research adopts a sociotheological approach to religious studies, drawing upon framework by Mark Juergensmeyer, Émile Durkheim and Pierre Bourdieu, among others, to frame the influence of the Sikh past on the militants’ own plane of reference.
