TAX REVISIONS OF 2004 AND PRO SPORTS TEAM OWNERSHIP

Tax law revisions of 2004 altered the “roster depreciation allowance” enjoyed by pro sports team owners. Supporters claimed this would practically eliminate costly legal oversight by the IRS and, ultimately, increase owner tax bills. Government officials and leagues remained silent on team value impacts but outside analysts argued they would rise by 5%. We model this policy change and investigate it empirically. Supporters in Congress were absolutely correct that owner tax payments should increase but outside analysts underestimated team value increases by half. No wonder Major League Baseball and the National Football League favored the revision.

Merit Without Measure: Notes on Buddhist Charity in Xiamen, Fujian

In recent years, a growing number of Buddhist groups have established officially registered charitable foundations. One response to this development from political scientists has been to ask whether or not the growth of religious charities signals the development of an autonomous civil society in the PRC, which might, in turn, promote democratization.This project is based on interviews with staff and volunteers from seven Buddhist charities in Xiamen, Fujian, and it argues that policies encouraging the development of Buddhist charities have interacted with developments within Buddhism during the reform period to encourage this recent growth. These policies aim to instrumentalize Buddhist charity to serve state policy goals related to social welfare and cohesion. However, Buddhist charity also continues to also draw on practices of almsgiving, merit-making, and ritual sponsorship that are not fully in alignment with, and are perhaps even subversive of, the utilitarian-productivist ethics promoted in the official discourse of the party-state

Hortas comunitárias urbanas e relações humanos e não humanos : habitar ruínas entre o campo e a cidade

Situada no campo de estudos entre o desenvolvimento rural e suas problemáticas e os estudos multiespécie, esta dissertação teve como recorte de pesquisa a Horta Comunitária da Lomba do Pinheiro, uma horta comunitária urbana, regida pelos princípios da agroecologia, aberta ao público, situada no bairro Lomba do Pinheiro, na Zona Leste de Porto Alegre/RS. A pesquisa de campo ocorreu do período de junho de 2021 a julho de 2022, período em que atuei como pesquisadora e trabalhadora do local. Em termos metodológicos, a pesquisa está alicerçada no método etnográfico, na observação participante, na elaboração dos diários de campo, por meio de gravações em áudio e fotografias, que foram as formas de apreensão das dinâmicas colocadas no campo. No que se refere ao conteúdo e aos objetivos deste trabalho, são apresentadas a relação rural e urbano e a possibilidade de abertura do campo dos estudos rurais para o estudo de relações que ultrapassam os humanos, bem como encontros e de narrativas que podem nos colocar a formular respostas mais interessantes ao que hoje é conceituado como Antropoceno. Este trabalho trata ainda sobre as formas de alimentação que se dão na Horta e como a produção de alimentos e do ato de alimentar-se está enredado com as formas de ser e estar no mundo dos humanos e que leva em conta o que os não humanos produzem nos humanos e com os humanos. Transversalmente a toda discussão usou-se como balizadores das análises os conceitos de atenção, cuidado e relacionalidade para a reflexão sobre as aberturas à diferença práticas e discursivas que a agricultura urbana agroecológica que o contexto local é capaz de produzir.Situated in the field of studies between rural development and its problems and multispecies studies, this dissertation had as its ethnographic field the Horta Comunitária da Lomba do Pinheiro, an urban community garden, ruled by the principles of agroecology, open to the public, located in the Lomba do Pinheiro neighborhood, in the East Zone of Porto Alegre. The ethnography took place from June 2021 to July 2022, period in which I acted as a researcher and worker at the site. Using the ethnographic method, participant observation, field diaries, audio recorded conversations, and photographs were the ways of apprehending the dynamics placed in the field. The first chapter contextualizes the rural-urban relationship and the need to open the field of rural studies to relationships that go beyond humans. It tells the story of Lurdes and Benjamin, farmers who migrated to Porto Alegre and are the founders of the Vegetable Garden project. In the second chapter, we thought about how urban agriculture and the Community Garden of Lomba do Pinheiro open possibilities of encounters and narratives that can help us formulate more interesting answers to what today is called the Anthropocene. In the last chapter we reflected on the ways of feeding that take place in the Horta and how the production of food and the act of feeding is entangled with the ways of being and being in the human world and that takes into account what non-humans produce in humans and with humans. Transversely to all the discussion, the concepts of attention, care, and relationality were used as a guide for the analysis to reflect on the openings to practical and discursive differences that agroecological urban agriculture and, locally, the Community Garden of Lomba do Pinheiro are able to produce

Changing Tastes: Purchase Choice in Urban China.

Food purchase options have expanded greatly in urban areas in the People\u27s Republic of China as a result of recent market reforms. Still, given the influences sociocultural factors, the restructuring of food consumption in China need not be expected to follow patterns observed in the West. This investigation of food purchase behavior was based on a ten-month period of field study in Nanjing, China. The adoption of time related food purchase behaviors was studied, including use of processed food, restaurant use, and frequency of food shopping trips. Food consumption habits were investigated in the context of how these patterns contribute to the economic efficiency of the household, as well as the definition, maintenance, and enhancement of social identities and relationships. Methods used to investigate food consumption patterns included participant observation, structured observations of food shopping, household inventories, focus groups of primary food shoppers, food retailer interviews, and study of the popular media. Following a pretest of the measures, a representative sample of 330 primary food purchasers in the 11 zip code areas of Nanjing were surveyed via household interviews. These data were used to test a structural equation model linking sociocultural and economic factors to time reduction food purchase behaviors. The results of the study indicate that the availability of both time and money are important predictors of use of time related products of many types, but that attitudes toward change in general are also important influences. In addition, the findings from this study reinforce a growing stream of research that finds that consumption choices are linked to self definition and the maintenance of relationships. Food consumption patterns are rooted in a cultural ideology, influenced by material needs, but relying more on history, habit, inertia, and an aesthetic sensibility to shape consumption patterns. For urban Chinese food shoppers, maintaining traditional patterns of food consumption serves to reinforce the importance of family stability and ritual amidst the whirlwind of change

1: Mass asymmetric fission barriers for {sup 98}Mo; 2: Synthesis and characterization of actinide-specific chelating agents

Excitation functions have been measured for complex fragment emission from the compound nucleus {sup 98}Mo, produced by the reaction of {sup 86}Kr with {sup 12}C. Mass asymmetric fission barriers have been obtained by fitting the excitation functions with a transition state formalism. The extracted barriers are {approximately} 5.7 MeV higher, on average, than the calculations of the Rotating Finite Range Model (RFRM). These data clearly show an isospin dependence of the conditional barriers when compared with the extracted barriers from {sup 90}Mo and {sup 94}Mo. Eleven different liquid/liquid extractants were synthesized based upon the chelating moieties 3,2-HOPO and 3,4-HOPO; additionally, two liquid/liquid extractants based upon the 1,2-HOPO chelating moiety were obtained for extraction studies. The Pu(IV) extractions, quite surprisingly, yielded results that were very different from the Fe(III) extractions. The first trend remained the same: the 1,2-HOPOs were the best extractants, followed closely by the 3,2-HOPOs, followed by the 3,4-HOPOs; but in these Pu(IV) extractions the 3,4-HOPOs performed much better than in the Fe(III) extractions. 129 refs

Fecundity limits in Frangula alnus (Rhamnaceae) relict populations at the species' southern range margin

The geographic range of many temperate plant species is constrained by climate, but it remains little known how climate affects population performance at low-latitude range margins. This study investigated the reproduction of the Eurasian tree Frangula alnus in relict populations near its southwestern range limit in southern Spain. The aim was to identify the principal stages and causes of ovule loss experienced by these marginal populations. More than 6,800 flowers were monitored over 2 years, insect observations and different experiments were carried out to assess levels of pollen and resource limitation, as well as the influence of flowering phenology on seed production. Most ovule losses occurred during flower anthesis and were due to strong cross-pollen limitation. Fruit set was affected by tree size, light regime and flowering phenology, probably through their effects on pollinator behaviour. Fruit set was almost zero throughout the first half of the flowering season. Then it increased paralleling changes in pollinator abundance but was soon overridden by increasing ovule desiccation due to summer drought. Successful seed production was mostly confined to a brief period near the end of the flowering season. Adverse weather during this period in the second study year resulted in a threefold bud and flower mortality and a 50% decrease of fruit production. Spring rainfalls in southwestern Spain have diminished more than 30% through past decades leading to an earlier onset of summer drought. This trend and its adverse effects on seed production may contribute to explaining the recent decline of F. alnus at its southwestern range limit. © Springer-Verlag 2005.Peer Reviewe

Do desenho analógico para uma ambiência digital : dentro da linha / fora de linha

O presente trabalho visa analisar a construção da obra Dentro da Linha / Fora de Linha (2019) , que se dá através de um processo que inicia analogicamente no desenho de caneta esferográfica, e se desdobra a partir da digitalização e manipulação das imagens produzidas, alterando não só o material, mas as especificidades inerentes da prática. É objetivado, através de teorias de arte e tecnologia, contextualizar o percurso que a obra veio a desencadear, buscando aproximações com conceitos que permitem uma visão de arte que privilegia processos que se dão de maneiras diversas, aceitando a possibilidade de contaminação entre diferentes meios, com o intuito de criar outras possibilidades à eles.The present work aims at analyzing the construction of the Dentro da Linha / Fora de Linha(2019) work, which takes place through a process that starts analogically in the drawing of a ballpoint pen, and unfolds from the digitalization and manipulation of the produced images, altering not only the material but the inherent specificities of the practice. Through the theories of art and technology, it is objectified to contextualize the course that the work started to unleash, seeking approaches with concepts that allow an art vision that privileges processes that occur in different ways, accepting the possibility of contamination between different media, with the intention of creating other possibilities for them
