Perceptions of Naturalized Playgrounds: A Qualitative Study

Hamarstrom, Jeffrey C. 01 May 2012 (has links)
Play is an important part of childhood that helps to develop social skills and ensure proper mental and physical development. There is a growing concern among parents and play researchers that technology and urbanization are limiting children’s access to the natural environment. This is encouraging play designers to create playgrounds that are based more on natural elements, such as water, plants, hills, tree groves, and rock outcrops, rather than manufactured equipment. Because environments can affect the behaviors that occur in them, a growing number of studies have focused on how naturalized play environments impact the development of children as they play. However, few studies have addressed how people who are interacting with naturalized playgrounds view them. This thesis discusses the findings of a qualitative research project that aimed to understand if naturalized playgrounds at mostly educational facilities were being viewed as viable play environments by examining supervisors’ and teachers’ perceptions of how the playground was being used. The naturalized playgrounds in this study contained about two thirds natural elements and one third manufactured elements. Most participants in the study felt that the term "naturalized" adequately characterized the play facility under their supervision. They also showed an active interest in furthering their education about naturalized playgrounds and saw their role as a facilitator of play. Naturalized playgrounds were viewed by participants as providing viable play options for children and, in most cases, a better option than traditional playgrounds due to the open-ended play opportunities the natural elements promoted. Participants in this study saw the heavy and continual use of natural elements promoting benefits such as a connection to nature, educational opportunities, and creating a dynamic playground that was interesting all year. When looking at how children used the environment, the perception was that a less formally structured playground provided an environment that everyone could enjoy. This also promoted more creative play that allowed for many types of play as opposed to the mainly physical play of traditional playgrounds. Data also showed that individual elements tend to promote specific types of play, which makes having a broad diversity of elements important.

Essays in Political Economy of Redistribution and Immigration

Greco, Rosalia January 2016 (has links)
Thesis advisor: Hideo Konishi / Thesis advisor: Alberto Alesina / This dissertation studies the interaction of politicians’ and voters’ incentives and its effect on redistributive and immigration policies. The first chapter ``Redistribution, Polarization, and Ideology'' focuses on the effect of income inequality and party polarization on redistributive policy, both theoretically and empirically. I demonstrate that income inequality and party polarization on social issues push redistributive policy in opposite directions. In particular, when the importance of ideology for the voters rises with their income, polarization discourages redistribution. Using data from the American National Election Study and the Census, I verify that it is indeed the case that the importance attached to ideological issues is increasing in the voters' income. Effects of ``income elastic'' ideology can account for the observed stability of redistribution policy in the U.S. The second chapter, ``Foreign Born U.S. Citizens and Immigration Policy'', studies the impact of immigration on immigration reforms, and decomposes the effects of naturalized and non-naturalized immigrants. Using Census data and roll call votes for the House on 2005 and 2006 immigration bills, we find that immigration affects Democratic and Republican parties differently. While the effect of non-naturalized immigrants can be explained by congressional district's socio-economic characteristics, naturalized immigrants exert an additional effect linked to their ability to vote in congressional elections. Higher naturalized immigrant population increases the probability that Democrats vote in favor of immigration, and decreases it for Republicans, suggesting opposite electoral incentives for the two parties, that can be interpreted in a framework of rational office-motivated incumbents seeking reelection. / Thesis (PhD) — Boston College, 2016. / Submitted to: Boston College.

NATURE IN THE CITY: Ecological Consciousness Development Associated with Naturalized Urban Spaces and Urban Forest Values in Calgary, AB and Halifax, NS

Peckham, Shawna C 12 October 2010 (has links)
In an increasingly urbanized world, how cities are designed and built affect how urbanites connect to the natural world and develop an ecological consciousness. Findings indicate that people value different urban landscapes for unique reasons but that urban trees provide numerous aesthetic, psychological, social, educational, ecological, moral and economic benefits. Many urban forest values are interwoven across these value categories. How people defined nature, what emotional states the landscape engendered and how they were able to actively engage with natural elements within urban landscapes all influenced participants? sense of belonging to a broader natural community. Overall, findings support the notion that naturalized spaces, even small spaces, can invoke a sense of connectedness with nature within participants. Yet, many respondents suggest that urban nature experiences may not be enough for the general population to develop an ecological consciousness, rather that they require additional educational support.

Percepção e autoconsciência : modelos experimentais na naturalização da fenomenologia

Castro, Thiago Gomes de January 2013 (has links)
Tese dividida em cinco capítulos, sendo três capítulos sobre teoria fenomenológica e naturalização nas Ciências Cognitivas e dois capítulos experimentais sobre percepção espaço-corporal, autoconsciência e affordance. O primeiro capítulo traça aspectos históricos da definição de intencionalidade e percepção de movimento próprio na Fenomenologia de Edmund Husserl em contraste com modelos de intencionalidade em outros sistemas filosóficos. O segundo capítulo explora a relação da Fenomenologia com psicólogos experimentais alemães nas duas primeiras décadas do século XX e a utilização do método fenomenológico para fins experimentais. O estudo dois também trata das decorrências indiretas da teoria fenomenológica na composição do argumento ecológico da percepção direta (James J. Gibson). O terceiro capítulo se ocupa dos modelos de naturalização da Fenomenologia nas Ciências Cognitivas, enfatizando o modelo de Fenomenologia Front-loaded como recurso metodológico que será empregado na seção experimental seguinte. No quarto capítulo, início da seção experimental, a percepção corporal, a habilidade cognitiva de representação de espaços e a autoconsciência são investigadas em uma tarefa experimental denominada Ilusão da Mão de Borracha (IMB). Os achados indicam correlação positiva entre um padrão de estimulação tátil em sincronia, entre mão real e prótese estética, com alterações tipificadas na capacidade de estimar distâncias numéricas. Traços estáveis de autoconsciência correlacionaram com as variações de estimativa espacial, mas não com as características descritivas da percepção da ilusão sensorial. No quinto capítulo investiga-se a interferência específica da estimulação tátil, sem presença de prótese estética, na habilidade de seleção de estímulos visuais por efetores manuais em uma relação de compatibilidade espacial (Efeito Simon). O experimento também testa o efeito da oclusão visual de um dos membros superiores sobre a compatibilidade espacial esperada pelo Efeito Simon entre o efetor ocluído e os estímulos visuais. Os resultados evidenciaram um aumento significativo dos tempos de reação das respostas manuais incompatíveis com o hemicampo visual, quando em condição de estimulação tátil. Ademais, houve decréscimo nos tempos de reação, sob a condição de estimulação tátil, para as respostas de compatibilidade espacial em ambos os efetores. Em contraste, a oclusão de um dos membros superiores não gerou diferenças importantes quando comparada à condição controle de resposta sem interferência. A autoconsciência corporal, tomada no experimento por uma escala de autorrelato, informou correlação positiva com modificações da resposta manual de seleção dos estímulos em tempos de reação na casa dos 20ms. Novamente, uma escala de autorrelato sobre autoconsciência corporal indicou interação com o desempenho. Nesse caso, com variações de ação seletiva manual em tempos de reação abaixo do nível de consciência da experiência. A repercussão dos achados é discutida junto à Teoria da Codificação de Eventos (TEC), que interpreta a seleção de estímulos por vieses intencionais prévios diretos no ambiente, não reflexivos ou representados conscientemente. Repercussões da Fenomenologia Front-loaded como opção metodológica nos dois experimentos são debatidas no contexto das Ciências Cognitivas. / Dissertation divided in five chapters: the first three chapters on phenomenological theory and it’s naturalization in Cognitive Sciences, and the two last chapters on experimental research about spatial and body perception, self-consciousness and affordance. The first chapter traces the historical aspects of the definition of intentionality and kinesthesia in the Phenomenology of Edmund Husserl, contrasting it to models of intentionality in other philosophical systems. The second chapter explores the relationship between phenomenology and German experimental psychologists in the first two decades of the twentieth century and their appropriations of the phenomenological method for experimental purposes. The chapter also addresses the indirect consequences of phenomenological theory for the composition of the ecological argument on direct perception (James J. Gibson). The third chapter deals with models of Phenomenology naturalization in Cognitive Sciences, emphasizing the front-loaded phenomenology model as a method that will be employed in the experimental section. In the fourth chapter, the beginning of the experimental section, body perception, cognitive ability for space representations and self-consciousness were investigated through an experimental task called Rubber Hand Illusion (IMB). The findings indicated a positive correlation between a pattern of synchronous tactile stimulation, between real hand and rubber hand, and typified changes on numerical distance estimations. Stable traces of self-consciousness correlated with space estimations variations, but not with descriptive features of the sensory illusion perception. The fifth chapter investigates the specific interference of tactile stimulation, without the rubber hand, on visual stimuli selection abilities performed by manual effectors in a spatial compatibility task (Simon Effect). The experiment also tests the effect of hemilateral visual occlusion of an upper limb on the spatial compatibility task. The results evidenced a significant increase in reaction times for manual responses towards incompatible stimuli, when the participants were stroked by the paintbrush on their right hand. Moreover, there was a decrease in reaction time, under the condition of tactile stimulation, for compatible responses on both effectors. In contrast, the occlusion of one arm yielded no significant differences when compared to the control condition without any interference. Body self-consciousness, taken by a self-report measure, had a positive correlation with changes in response selection at 20ms reaction times. Again, a self-report scale of self-consciousness indicated interaction with performance. In this case, with variations of selective action for reaction times below the level of conscious experience. The impact of the findings is discussed within the Theory of Event Coding (TEC) framework, which interprets the selection of stimuli by previous direct intentional bias on the environment, not reflective or consciously represented. Implications of Phenomenology Front-loaded as the methodological option in both experiments are discussed in the context of Cognitive Sciences.

Apriority in Naturalized Epistemology: Investigation into a Modern Defense

Christiansen, Jesse Giles 28 November 2007 (has links)
Versions of naturalized epistemology that overlook or reject apriority ignore innate belief-forming processes that provide much of the grounding for epistemic warrant. A rigorous analysis reveals that non-experiential ways of viewing apriority, such as innateness, establish the domain for a plausible naturalistic theory of a priori warrant. A moderate version of naturalistic epistemology that embraces the non-experiential feature of apriority and motivates future cognitive scientific research is the preferred account.

Rethinking Ethical Naturalism: The Implications of Developmental Systems Theory

Kinggard, Jared J.. 28 October 2010 (has links)
Biological research has the capacity to inform ethical discussions. There are numerous questions about the nature of sexual orientation, intelligence, gender identity, etc., and many of these questions are commonly approached with the benefit of implicit or explicit biological commitments. The answers to these sorts of questions can have a powerful impact on social, ethical, and political positions. In this project I examine the prospect of naturalizing ethics under the umbrella of developmental systems theory (DST). If one is committed to DST, then those ideas involved in DST that steer biological research will also have implications for ethics. There has been much debate over whether certain human traits or attributes are the consequence of nature or nurture. This kind of question tends to be articulated in dichotomous terms where the focal point of the discussion is over which opposing causal mechanism asserts the most power over the development of these attributes. The debate places particular importance on such distinctions as that between gene and environment, and biology and culture. DST seeks to dismiss such dichotomous accounts. In this sense, DST is an attempt to do biology without these dichotomies. In the process, DST articulates a reconceptualized notion of "the natural." I am interested in how DST’s reconceptualization of the natural can inform a naturalistic approach to ethics. Thus, the aim of this project is to examine the ramifications of taking DST as a guiding principle in the naturalization of ethics.

ENHANCING BENEFICIAL INSECT BIODIVERSITY AND BIOLOGICAL CONTROL IN TURF: MOWING HEIGHT, NATURALIZED ROUGHS, AND OPERATION POLLINATOR

Dobbs, Emily 01 January 2013 (has links)
The goal of this study was to evaluate several sustainable turf maintenance techniques for their potential to increase beneficial insect populations, which could then provide ecosystem services including pest suppression and pollination. The three techniques in question were 1) raising mowing height in commercial and residential lawns, 2) establishing naturalized roughs on golf courses, and 3) creating pollinator refuges on golf courses through the program Operation Pollinator. We found that raising mowing heights did increase populations of some predators such as spiders and staphylinids, but did not increase predation, which was ubiquitously high because ant populations were unaffected by mowing height. In addition, we found that pests reared in high-mowed grass were less likely to survive and gained weight more slowly than when raised in low-mowed grass. On golf courses, we found that naturalized roughs and traditional roughs supported different populations of predators, but contrary to our original hypothesis, naturalized roughs had little impact on biological control on the rest of the golf course. Operation Pollinator was successful in supporting 49 species of pollinators, including rare and declining bumble bees, demonstrating that turf systems can provide valuable pollinator conservation services, especially in urban systems where pollinator habitats are already rare.

Os dados utilizados no estudo fazem parte do banco de dados do setor de suínos da Fazenda de Ensino, Pesquisa e Extensão da Unesp – Campus de Ilha Solteira - SP. No primeiro estudo foram selecionados e classificados resultados de desempenho reprodutivo (nascidos totais, nascidos vivos, perdas, mortalidade 1 a 21 dias, mortalidade do nascimento ao desmame, peso ao nascimento, peso aos 21 dias, peso aos desmame, ganho de peso até 21 dias e ganho de peso diário até o desmame) de 332 parições oriundas de acasalamento entre machos e fêmeas da raça Moura no período de 2006 a 2016. Para a classificação foram consideradas as ordens de parto (da primeira à sétima) e as estações do ano (primavera, verão, outono e inverno). A estação do ano pouco influenciou no desempenho das matrizes, mas os partos de 4ª e 5ª ordem apresentaram os melhores resultados para número de nascidos vivos e peso ao nascimento. No segundo estudo foram avaliados 60 partos, 30 provenientes do acasalamento de machos e fêmeas puros da raça Moura, e 30 provenientes do cruzamento entre fêmeas Moura e machos MS115, totalizando 526 leitões para avaliação até o desmame. Os partos foram classificados de acordo com a origem genética do macho, ordem de parto e estação do ano. De forma geral a origem do macho não interferiu (P>0,05) no número total de leitões nascidos/parto, leitões vivos/parto e taxas de mortalidade, porém o cruzamento da fêmea Moura com o macho MS115 promoveu melhor (P<0,05) desempenho das leitegadas até o desmame. Independente da origem genética do macho, para 3ª ordem de parto foi observado o maior de leitões nascidos e leitões vivos/parto (P<0,05), mas também a maior mortalidade até o desmame. / The objective of this study is to provide data for reproductive and productive performance Moura breed sows kept in semi-intensive system and to evaluate the potential use of Moura sows crossing with synthetic male, MS115, for the production of piglets. The data used in the study are part of the pig farm database of Farm Research, Education and Extension UNESP –Ilha Solteira - SP. In the first study were selected and classified results of reproductive performance (total number of piglets born/parturition, alive piglets/parturition, losses, mortality 1 to 21 days, mortality at weaning, birth weight, weight at 21 days, weight at weaning, daily weight gain up to 21 days and daily weight gain until weaning) 332 parities derived from mating between males and females of Moura breed from 2006 to 2016. For classification were considered the parturition order (the first to seventh) and seasons (spring, summer, autumn and winter). The season had little influence on the performance of the sows, but the 4th and 5th birth order showed the best results for number of live births and birth weight. In the second study we evaluated 60 births, 30 from the mating males and females of Moura breed and 30 from the cross between Moura sows and MS115males, totaling 526 piglets for evaluation until weaning. The births were classified according to genetic male, parturition order and season. In general, the male origin did not affect (P>0.05) the total number of piglets born/parturition, living piglets/parturition and mortality rates, but the crossing between Moura female and MS115male promoted better (P <0.05) performance of piglets until weaning. Regardless of the genetic male origin, in the 3rd parturition order occurred the largest number of piglets born/parturition and alive piglets/parturition(P<0.05), but also the highest mortality until weaning(P<0.05).
