This qualitative, phenomenological study examined teachers' experiences of the policy context of the fall of 2013 in the School District of Philadelphia. It was an extremely turbulent time resulting from a cascading policy environment with origins in federal government mandates. The study focused on ten teachers' perceptions of policy implementation in one comprehensive high school. Each teacher was interviewed once in the summer of 2017. State, local, and school specific policy forces were examined. Turbulence theory anchored the study. Teacher interview data were used to construct a turbulence gauge for the school, shedding light on teacher perceptions of the magnitude of disruption. Events from 1997 to 2013 in the School District of Philadelphia provided evidence that policy forces from different governance levels and various contextual factors cascaded upon each other yielding a crescendo of policy implementation experienced by teachers in the fall of 2013. Findings indicated that teachers' perceptions of policy implementation during the fall of 2013 were traumatic, chaotic, and compliance-driven. Teachers primarily held the district responsible for the state of affairs, then the principal, and lastly, the federal government. A finding of severe turbulence was assigned to the school reflecting teachers' perceptions of policy implementation. This study informs school leaders in domains related to policy implementation, strategic planning, and impacts on human capital. Future studies should examine how policy implementation in the NCLB era manufactures an up-tempo change culture which converges on teachers and impacts their perceptions of efficacy and capacity to deliver instruction. Key terms: policy implementation, NCLB, Turbulence Theory, Philadelphia, affective, school closings / Educational Administration

Levando em consideração as contribuições de Schegloff e Sacks (1973), Button (1987) e Button (1990), dentre outras concepções teórico-metodológicas, este trabalho tem os seguintes objetivos: (1) mapear algumas formas lingüísticas que desempenham a função de encerrar a conversa telefônica cotidiana em contexto brasileiro e (2) evidenciar as estratégias de negociação que os participantes utilizam para encerrar ou para continuar o telefonema. O corpus se constitui de dados reais de fala espontânea, gravados em uma família juizforana, e traduzem um pouco como os participantes, em contexto brasileiro, constroem as relações sociais micro-seqüencialmente em conversas desse gênero. Enfim, esta pesquisa ratifica a noção de senso comum de que encerrar uma conversa é uma questão delicada para os participantes, uma vez que eles podem lançar mão de várias estratégias de negociação para encerrar ou continuar a conversa entre o primeiro “então ta” e o último “tchau”. / This study looks at the everyday telephone conversation closings, under the perspective of ethnomethodological Conversation Analysis. By the contributions of Schegloff & Sacks (1973), Button (1987) and Button (1990), among others theoretical-methodological conceptions, this work has the following aims: (1) to look into some linguistic forms that play the role of finish the everyday telephone conversation in Brazilian context and (2) to evidence the negotiation strategies used by the participants for closing or for continuing the call. The corpus is composed of data of talking occurring naturally, recorded in a family located at the Brazilian city of Juiz de Fora, and translates a bit how the parts, in Brazilian context, build the social relationship microsequentially in conversations like that. Thus, this study confirms the commonsense notion about finishing a conversation as a delicate issue for the participants, because they can use many negotiation strategies to closing or to continuing the conversation between the first “então tá” and the last “tchau”.

As a result of globalisation, the number of companies working globally is increasing at an unprecedented pace. Consequently, the need to communicate with people from other countries is getting bigger. In such intercultural communication, a common language must be used to interact. The language of choice is most often English, which is the business lingua franca (BELF) today. Furthermore, email has become the obvious choice of medium when interacting with foreign business associates. The present study was conducted through intensive and extensive analyses, investigating BELF emails written by 21 individuals with 14 different native languages. The data consists of 209 emails. The study follows Bjørge’s (2007) work on formality in emails written in academic settings. The aim of the study was to determine how formal the participants were in greetings and closings and whether they accommodated their language to the respondent. The results suggest that the level of formality mainly depends on the purpose of the email and, to some extent, how formal the correspondent is. The accommodation to the correspondent seems to be individual. The present study wishes to extend knowledge on email communication in BELF settings. The results are likely to be relevant for teachers and students of Business Communication and English as a Second or Foreign Language along with managers in internationally functioning companies, especially as regards what should be considered in BELF communication.

The concept of “Environmental authoritarian” becomes the focus of discussion in the academic field of environmental politics since it has limited observations. In the recent years, the severe air pollute issue is considered as a threat by both citizens and authorities in China. Along with the more stricter environmental protection laws being issued, even the measures of the factory closings and coal ban seems to become acceptable as the population  have suffered in the heavy smog for years. Does this led to the rise of “environmental authoritarian” in China?  Taking this as a heuristic point, I observe the positions of various stakeholders in the environmental governance as well as present the findings from research on the implementation and enforcement of air pollution controls measures in Jing-Jin-Ji region. I offer a critical examination of “environmental authoritarian”, especially the levels of public participation at the policy process. After to do the research, the key funding is that the concept of “Environmental authoritarian” is too simplified, it cannot cover the complex and detailed environmental governance at local empirical cases.

A stochastic differential equationdriven by a Brownian motion where the dispersion is determined by a parameter is considered. The parameter undergoes a change at a certain time point. Estimates of the time change point and the parameter, before and after that time, is considered.The estimates were presented in Lacus 2008. Two cases are considered: (1) the drift is known, (2) the drift is unknown and the dispersion space-independent. Applications to Dow-Jones index 1971-1974  and Goldmann-Sachs closings 2005-- May 2009 are given.

This dissertation consists of three essays in the field of health economics. The first essay provides the first causal evidence that bargaining power in a relationship shapes pregnancy outcomes and health disparities in the US. A key driver of bargaining power is the availability of potential non incarcerated male partners in the local dating market, which I define at the race by cohort by county level. Because these sex ratios are endogenous, I use a novel instrument that leverages the randomness in sex at birth and the persistence of local demographics to isolate exogenous variation in the relative availability of men. Greater female bargaining power causes better outcomes: fewer out-of-wedlock births, less chlamydia and hypertension among mothers, and fewer infants with APGAR score below the normal level. The marriage market makes a significant contribution to racial disparities in pregnancy health. Specifically, Black women face relatively poor prospects when looking for a partner compared to White women: while there are 102 White men per 100 White women, only 89 Black men are available per 100 Black women. According to my estimates, Black women’s disadvantage accounts for 5-10% of the large racial gap in maternal and neonatal health. The racial difference in male availability is mostly policy-driven, as incarceration accounts for 45% of the gap. A counterfactual policy equalizing county-level incarceration rates for non-violent offenses between Black and White people would prevent 200-700 adverse pregnancy outcomes per year among Black mothers through the bargaining power channel alone. The second essay investigates how reopening hotels and ski facilities in Poland impacted tourism spending, mobility, and COVID-19 outcomes. We used administrative data from a government program that subsidizes travel to show that the policy increased the consumption of tourism services in ski resorts. By leveraging geolocation data from Facebook, we showed that ski resorts experienced a significant influx of tourists, increasing the number of local users by up to 50%. Furthermore, we confirmed an increase in the probability of meetings between pairs of users from distanced locations and users from tourist and non-tourist areas. As the policy impacted travel and gatherings, we then analyzed its effect on the diffusion of COVID-19. We found that counties with ski facilities experienced more infections after the reopening. Moreover, counties strongly connected to the ski resorts during the reopening had more subsequent cases than weakly connected counties. The third essay studies the diffusion of influenza-like illnesses (ILI) through social and economic networks. Using almost two decades of weekly, county-level infection and mortality data from Poland, it studies within and across-counties ILI transmission. Firstly, it evaluates the causal effect of school closures on viral transmission. The results show that closing schools for two weeks decreases the number of within county cases by 30-40%. The decline in infections extends to elderly and pre-school children. In addition, flu-related hospitalizations drop by 7.5%, and mortality related to respiratory diseases among the elderly drops by 3%. Secondly, the paper demonstrates the significant contribution of economic links to diffusion across counties. The disease follows the paths of workers commuting between home and workplace. Together with the structure of the labor mobility networks, these results highlight the central role of regional capitals in sustaining and spreading the virus.

This dissertation consists of three essays in public economics. The three chapters focus on interactions between public and private economic decisions. The first two chapters focus on unemployment insurance (UI) policy in the United States. The third discusses public-private interactions in the education market. The first chapter, a joint work with Arindrajit Dube, Calvin Jahnke, Raymond Kluender, Suresh Naidu, and Michael Stepner estimates the labor supply and spending responses to a large change in UI benefits during the pandemic. We examine the effects of the sudden withdrawal of expanded pandemic unemployment benefits in June 2021 using anonymized bank transaction data for 16,548 individuals receiving UI in April 2021. Comparing the difference in differences between states withdrawing and retaining expanded UI, we find that UI receipt falls 35 p.p. while employment rises by only 4.4 p.p. by early August. Average cumulative UI benefits fall by $1,385 while average cumulative earnings increase by only $93. Heterogeneity by unemployment duration implies that these effects are primarily driven by extensive margin expiration of benefits, rather than intensive margin reductions in the benefit level. The second chapter examines the role of gifts and loans from friends and family during unemployment. These transfers play a largely unstudied informal insurance role in high-income countries, making it difficult to assess their implications for social insurance policy. I present new results on informal insurance paid via person-to-person (P2P) payment platforms using a survey-linked administrative bank transaction dataset covering 130,502 low-income users from the US who were unemployed at least once between July 2019 and September 2020. Event study estimates show average monthly inflows from all P2P platforms increase by $30, or 2% of lost earnings, one month after job loss before returning to baseline over 10 months. Single mothers and the long-term unemployed receive the largest increases, as do those living in high-income areas. I exploit three plausibly exogenous changes to federal pandemic unemployment insurance (UI) policy to estimate that UI benefits crowd out at most $0.04 of informal P2P transfers. Using the social insurance framework introduced in Chetty & Saz (2010), my crowd-out estimates indicate negligible welfare consequences for an additional dollar of benefits. Altogether these results imply that public UI benefits can raise welfare by pooling risk across networks without reducing within-network targeting of informal insurance. The third chapter asks whether public school services fill in gaps left by private school failures. Specifically, it explores what type of schools enter the market and experience an increase in enrollment after reports of abuse by Catholic priests lead to Catholic Schools closures. I use a two-way fixed effects event study method to estimate a change in enrollments and number of different types of schools after a report of priest abuse within the same zip code, school district, or county. I find there are 0.2 fewer Catholic schools and Catholic school enrollment falls by 75 students after six years, which are offset by a 0.2 and 50-student increase in charter school counts and enrollments on average. These increases are unique to charter schools and is not observed in other public or non-Catholic private schools. Altogether, these results suggest that former Catholic schooled families show a preference for charter schools over other public schools, which may be due to the low-cost and similar emphasis on discipline and academic achievement.

This thesis has presented a comprehensive study on the abandonment of historic school buildings by the Indianapolis Public Schools system from 1970 to 1997. During this period, IPS closed or demolished sixty-four city schools representing nearly fifty-three percent of all Indianapolis public schools in 1970. The principal reason behind the facility closings was a dramatic decline in student enrollment beginning in 1967, but rapidly accelerating after 1970.Several factors contributed to this fall in public school rolls: lower birth rates, the unified government system (Unigov) that merged Indianapolis and Marion County administrative functions, and highway construction and urban renewal projects that cleared large areas of residential neighborhoods. The most significant factor, however, was court mandated integration of Indianapolis public schools in 1970, which led many white families to flee the IPS district and eventually resulted in one way, cross-district busing in 1981.The approaches adopted by Indianapolis Public School officials and the school board between 1970 and 1997, in response to the loss of student population, demonstrates an evolution of policy concerning historic school buildings in the city's inventory. During the early rounds of large scale closings, 1972-1975 and 1980-1981, IPS authorities specifically targeted older schools for closing. This policy changed during the last period of closings, 1995-1997, as some consideration was placed in closing decisions on school buildings' historic and architectural significance.Indianapolis Public School procedures governing the sale of surplus schools also went through a transformation between 1970 and 1997. Until recently, IPS was little concerned about the intended use of former schools by potential buyers. As a result, many historic school buildings were lost due to neglect or outright demolition. In 1997, however, Indianapolis school officials began to take responsibility for ensuring that historic schools leaving IPS's stewardship be preserved. / Department of Architecture
