”It grew a day of expectation” : A diachronic corpus study on the evolution of the verb grow in British English

Luokkala, Rosaleena January 2019 (has links)
English has an extraordinary number of labile verbs, that is, verbs that can be used both transitively with a causative sense and intransitively with an inchoative sense. This corpus-based study investigates the evolution of the verb grow from exclusively intransitive to labile in British English in the Late Modern English period. A random sample of 500 instances of the verb grow was drawn from the period 1710-1780 as well as from the period 1850-1920 of the Corpus of Late Modern English Texts in order to track diachronic changes. The instances in the samples were categorized according to their verb pattern and type of complement (if any), and instances of the past participle grown were also categorized based on the auxiliary used (be/have/none). The study suggests that grow came to be used transitively when resultative intransitive constructions (e.g. be grown (over)) were reanalyzed as passives; that the use of noun phrase complements with copular grow decreased and became archaic to make the distinction between copular and transitive uses less ambiguous; and that the fact that the be-auxiliary was replaced by the have-auxiliary in perfect constructions helped avoid ambiguity between intransitive and transitive uses of grow. Thus, the study provides some empirical evidence for Visser's (1963) hypothesis that the change from be- to have-perfects played a central role in the acquisition of lability.

Simulação estocástica de elementos do clima para estimação da produtividade de cana planta / Stochastic simulation of climate elements to estimate the sugarcane productivity

Correa, Simone Toni Ruiz 22 February 2013 (has links)
Os modelos de simulação devem ser ajustados para que os valores dos parâmetros e variáveis de entrada forneçam resultados que melhor representem os valores observados. Assim, face às imprecisões a que estão sujeitos os resultados obtidos a partir do ajuste, há a necessidade de implementar métodos que permitam a avaliação das incertezas, quer seja nos parâmetros de cultura ou nas variáveis de entrada do modelo. Tem-se, para a cana-de-açúcar, que a máxima produtividade de açúcar ocorre no momento em que a Pol e a biomassa de colmos (TCH) são potencializados. Sendo assim, este trabalho objetivou: (i) testar a aderência de três distribuições de probabilidade (normal, gama e Weibull) aos dados diários de temperaturas média do ar e radiação solar global, em Piracicaba, SP; (ii) simular as variáveis temperatura do ar e radiação solar global por intermédio das distribuições normal bivariada, gama e Weibull, e a precipitação por intermédio da distribuição gama; (iii) propor um modelo, utilizando abordagem determinística para a variedade de interesse, para caracterizar a variação temporal do crescimento de biomassa seca de cana-de-açúcar e estimar a ordem de magnitude do período útil de industrialização (PUI), do dia de ocorrência do valor máximo da produtividade de sacarose (expressa em TPH) e das produtividades potencial e deplecionada de cana-de-açúcar, em dois ambientes de produção; (iv) estimar as variações das produtividades potencial, deplecionada por água e TPH (ciclo cana planta) por intermédio de procedimento estocástico para os elementos do clima (temperatura, radiação fotossinteticamente ativa e precipitação). As simulações utilizando as distribuições normal bivariada e gama são apropriadas por representarem melhor os elementos do clima; o modelo para a estimação das produtividades potencial, deplecionada e de sacarose apresentou resultados satisfatórios quanto aos objetivos propostos (abordagem determinística); o desempenho das variações das produtividades ocorreu de forma semelhante, no que se refere a magnitude de valores, para as simulações utilizando as distribuições normal bivariada e gama, e apresentou tendência de superestimar os valores das produtividades, para a simulação utilizando a distribuição Weibull (abordagem estocástica dos elementos do clima). / Simulation models should be adjusted by values of parameters and input variables in order to provide results that best represent the observed values. Thus, due to inaccuracies that are subject the adjustment´s results, it is necessary to implement methods for uncertainties evaluation for either, the parameters of the culture or input variables of the model. For the sugarcane, the maximum productivity of sugar occurs when both, Pol and biomass of stems (TCH) are the maximum. The aims of this study were: (i) to verify the adherence of three probability distributions (normal, gama and Weibull) to the daily data of average air temperature and solar radiation, in Piracicaba, SP; (ii) to simulate the variables air temperature and solar radiation through the bivariate normal, gama and Weibull distributions, and precipitation through the gama distribution; (iii) to propose a model, by using deterministic approach to the genotype of interest, to characterize the temporal variation in dry matter growth of sugarcane estimating the magnitude order of the useful period of industrialization, the date of occurrence in maximum sucrose yield (expressed by TPH) and the sugarcane potential and depleted productivity, in two production environments; (iv) to estimate the variability of potential, depleted by water and TPH (sugarcane plant cycle) through a stochastic procedure for the climate elements (temperature, photosynthetically active radiation and precipitation). The simulations by using bivariate normal and gama distributions are appropriate to better represent the climate elements; the model to estimate potential, depleted and sucrose productivity showed satisfactory results for the proposed objectives (deterministic approach); yield variability was similar, as regard the magnitude of values, for the simulations by using bivariate normal and gama distributions and it presented a tendency to overestimate the productivity for simulations by using Weibull distribution (stochastic approach of climate elements).

Desempenho agronômico de novas cultivares de bananeira (Musa spp.) na região de Piracicaba-SP / Agronomic performance of new banana cultivars (Musa spp.) at Brazil subtropical region, Piracicaba-SP

Andréa Ribeiro Domingues Rosa 22 February 2016 (has links)
O estado de São Paulo destaca-se como o maior produtor nacional de banana (Musa spp.), com sua produção comercial tradicionalmente concentrada na região do Vale do Ribeira e no Litoral Paulista. No entanto, os cultivos se estenderam a partir da década de 1990 para o Planalto Paulista, onde agricultores buscavam uma maior diversificação das atividades agrícolas. A prevalência do cultivo com cultivares tradicionais tem sido desafiadora devido à suscetibilidade dessas às principais doenças. Objetivou-se avaliar dois novos híbridos tetraplóides (AAAB) resistentes à Sigatoka amarela (Mycosphaerella musicola, Leach), a \'BRS Platina\' e a \'BRS Princesa\', comparando-os com a cultivar comumente utilizada, a \'Prata-anã\' (AAB). No entanto, a adoção de novos híbridos de bananeira não se estabelece apenas pela sua resistência às doenças. Dessa forma, variáveis vegetativas, variáveis de rendimento do cacho e suas correlações, duração do ciclo e qualidade pós-colheita dos frutos também foram avaliadas. O experimento foi conduzido no município de Piracicaba-SP (latitude: 22 43\' 30\'\' S, longitude de 47 38\' 56\'\' O e altitude de 554 metros), que possui clima classificado como Cwa, com chuva predominante no verão e período mais seco e frio no inverno. O delineamento experimental foi o de blocos ao acaso, com a adoção de três repetições e a parcela composta por três plantas. Quanto às avaliações da qualidade pós-colheita dos frutos, o delineamento experimental adotado foi o inteiramente casualizado, 12 dias de armazenamento, três repetições, cada qual constituída por três frutos. Os resultados foram submetidos à análise estatística de variância e ao teste de Tukey a 5% de significância; análise de correlação com base na correlação de Pearson e análise de regressão a 5% de significância. De acordo com os resultados obtidos, conclui-se que as cultivares BRS Platina e BRS Princesa apresentam maior resistência à Sigatoka amarela em relação à cultivar Prata-anã, porém não diferem quanto ao rendimento do cacho. Quanto ao crescimento vegetativo, destaca-se o maior porte apresentado pelas novas cultivares, BRS Platina e BRS Princesa, podendo conferir às essas cultivares maior suscetibilidade ao tombamento, principalmente devido a frequência de ventos fortes na região. Em relação ao ciclo de produção as cultivares não diferem entre si. Quanto à qualidade pós-colheita dos frutos, as bananas \'BRS Platina\' apresentam um amadurecimento mais acelerado e, consequentemente, senescência dos frutos. Somente a cultivar BRS Platina apresenta correlação positiva entre variáveis vegetativas e produção. / São Paulo state stands out as the main producer of banana (Musa spp.). The commercial production is mostly concentrated at Vale do Ribeira region and São Paulo coast. However, at the 1990 decade Banana cultivation started spreading towards the Paulista plateau where farmers sought cropping diversification. Maintaining the use of traditional cultivars has been challenging due to their susceptibility to main diseases.This study aimed evaluating two recently breed tetraploids hybrids (AAAB), \'BRS Platina\' and \'BRS Princesa\' resistant to yellow Sigatoka (Mycosphaerella musicola, Leach), comparing it to the commonly used \'Prata-anã\' cultivar (AAB). Knowing that the adoption of a new hybrid does not take place by simply considering its resistance to diseases, the evaluation of vegetative parameters, bunch yield and its correlations, cycle duration and post-harvest quality of the fruits were necessary. The study was installed in Piracicaba-SP (latitude: 22 43\' 30\'\' S, longitude de 47 38\' 56\'\' W e altitude of 554 meters), with Cwa climate classification where most rain occurs during summer and the winter is dry and cold. The adopted experimental desing was randomized blocks, with three replicates and three plants per plot. The post-harvest evaluations took place in a complete randomized desing, with three replicates and plots composed of three bananas. The results were submitted to analysis of variance and Tukey test at the level of 5% of significance; Pearson correlation analysis and regression analysis. The most valuable results related, the \'BRS Platina\' and \'BRS Princesa\' demonstre higher resistance to yellow Sigatoka when compared to \'Prata-anã\' but there are no difference in yield as a result of the components of the bunch of each cultivar. The news cultivars have pseudostem taller than \'Prata-anã\'. In terms of post-harvest quality, bananas \'BRS Platina\' has early fruit maturation, when compared to the others, and consequently sooner beginning off fruit decease process. Only the \'BRS Platina\' has positive correlation between vegetative and production parameters.

Building Interests in a Career in Teaching Among Latina/o Students at a Charter School

January 2019 (has links)
abstract: Teacher shortage crisis were consistent across the nation. Higher education institutions, K-12 school districts, and political leaders were actively seeking solutions to ensure classrooms did not sit vacant and were not staffed by individuals who are unqualified to teach. This mixed methods action research study examined one strategy for teacher recruitment by targeting high school students who attended a Title 1 school. Due to the growing Hispanic population in Arizona, coupled with the underrepresentation of Hispanic teachers compared to the number of Hispanic students, a particular focus was devoted to targeting Hispanic high school students as they represented a potential untapped pipeline of future educators. The study was conducted to explore factors that might increase student interest in declaring education as a major upon graduating from high school and eventually pursuing teaching as a career. Three theoretical frameworks guided the study: (a) Theory of Planned Behavior, (b) Self-Efficacy, and (c) Social Cognitive Career Theory. A total of 20 participants engaged in the intervention over the course of three weeks. The intervention included engagement in curriculum exposing students to the teaching profession as well as clinical experiences. Data gathered included pre- and post- intervention survey results and semi-structured interview questions. It was anticipated the intervention would increase students’ interest in becoming a teacher. Results demonstrated a decrease in intention post-intervention. Future research should examine alternative recruitment approaches for students who do not already have an interest in pursuing the profession. / Dissertation/Thesis / Doctoral Dissertation Educational Leadership and Policy Studies 2019

A Study of Guidance Curriculum in Hong Kong Primary Schools

Luk Fong, Yuk Yee Pattie, n/a January 2002 (has links)
This thesis examines the question of what kind of guidance curriculum is suitable for primary schools in Hong Kong. The call for the development of guidance curriculum for primary school children in Hong Kong arises from the needs of students: their need for enhancement of their self-concept, and has been translated into guidance and educational policy documents, and structural and administrative changes in schools which allow more time for the development of guidance in primary schools. Given that the educational context of Hong Kong is "East meets West," the researcher posits that, in studying guidance in Hong Kong, both Eastern and Western traditions in guidance must be taken into consideration. The researcher further argues that a guidance curriculum that is suitable for the primary school children in Hong Kong should start by looking at the particular experiences, expectations and tensions that educators, guidance professionals, teachers, parents and children are facing in the competing and changing contexts of the Hong Kong society. These expectations and tensions are very much related to the colossal changes in Hong Kong and are reflections of various degrees of overlaps between "East" and "West", as well as "past" and "present". The researcher has drawn on literature concerning globalization as hybridization, the Chinese concept of yin-yang and the psychological processes at work when Western modernization meet with indigenous Chinese culture, to explain the dynamics of change in the Hong Kong context. This thesis develops a hybrid framework for studying such changes. The framework consists of open-ended questions designed by the researcher from the literature, an adaptation of Confucian's cardinal relationships and Lawton's model for curriculum development A qualitative case study method is used for this study. Data are drawn from the author's own experience in a two-week teaching attachment in a primary school, and interviews with guidance professionals, primary school principals, teachers and students in three selected primary schools in Hong Kong. A qualitative study is chosen so that the multiple realities of teaching guidance in schools can be understood in their naturalistic settings. The boundary of the case is Hong Kong with its implementation of Hong Kong versions of Radd's (1993) Grow with guidance system. Three out of the eight Grow with guidance system pilot schools are studied. The chosen schools differ in student composition, school type, and methods of implementation of the guidance curriculum. Data are obtained by individual interviews, the in-depth study of one case study school by the researcher as participant observer, and content analysis of guidance materials in the case study schools. Data by these three methods and from different stakeholders are triangulated, as information obtained is checked against each other. This study uses multiple forms of evidences and they persuade by reason. Being a qualitative case study, its purpose is to illuminate but not to generalize. The criteria for judging the success of this study depend on the richness and accuracy of data, as well as the coherence, insight and instrumental utility in presenting and reading the data. The researcher argues for a hybrid guidance curriculum for the primary schools in Hong Kong to suit the hybrid contexts in Hong Kong. Data obtained from content analysis and the case study schools show that the philosophical, sociological and psychological factors as well as the content, pedagogies, organization for teaching and practical arrangements of the guidance curricula are hybrid in the Hong Kong implementation of Radd's Grow with guidance system. The researcher concludes that a useful guidance curriculum for Hong Kong primary schools must first listen to the different voices of all stakeholders about the guidance curricula and their "self-other relationships", for those voices reflect their tensions and reality. Much of their voices are presented as stories following the Chinese storying traditions. Methods to help children to deal with tensions and conflicts at personal, school, home and societal levels include giving up self to follow others [chinese characters omitted, knowing self and others [chinese characters omitted], awareness of and accommodation of differences [chinese characters omitted]context analysis, communication using culturally and contextually appropriate ways and emotional management. This thesis contributes to knowledge by inventing the concept of "hybrid guidance curriculum" to suit the hybrid context of Hong Kong. A new hybrid research methodology is also developed in this thesis which enables the forming of new categories of "self-other relationships" and new hybrid key concepts for the guidance curriculum. As such, this study allows for the re-reading of new ideas and practices of traditions in a modern hybrid society. Moreover, it also highlights the importance of the development of a reflexive self in which one negotiates one's own positions and one's relationships with others. In a special case, this study examines the fundamental issue of adapting and integrating western traditions in a country with different culture and contexts. Research frontiers, home school co-operation and implications to teacher educators, practitioners and policy makers in the guidance fields are discussed. Although this research is basically about Hong Kong, the findings may also be relevant to other places in the world where modernization has taken place in the indigenous culture.

The Research on the Growth Mechanism of Harbor Operation by using System Dynamics Methodology

Chen, Miau-Tang 04 August 2003 (has links)
The fiercer competition among international harbors drives every port to reinforce operation efficiency to attract carriers and to develop competition strategies to grow competence. In those years, Kaohsiung Harbor has slumped from the third to the fifth largest carrier harbor in the world. It is the overall symptom of competition risks for seaports in Taiwan. The severe situation, though, it is exactly what we can strive to revert the declining trend. Facing this topic composed of dynamic complexities, we can leverage systematic deliberation and dynamic simulation to revamp the status quo structure and create beneficial behavior model. In this thesis, we adopt system dynamics to build up a typical dynamic harbor model to dig out the crucial facets key to the growth of an international seaport and henceforth serve for basis of the decision-making. The main conclusions of this research are as follows: 1.The four facets that influence the development of a harbor are ¡§The economic strength of the hinterland,¡¨ ¡§The completeness of the harbor facilities, whether the construction of the harbor can keep in pace with the volume of containers,¡¨ ¡§The openness of the harbor,¡¨ ¡§The superiority of the geographic location.¡¨ 2.Whatever the import, export, or even transfer, the rate policy of a harbor will help little to the growth of the volume of containers with the other conditions unchanged. The disastrous effect of rate slash will be revenue decline; keeping volume while losing profit. In the long term, it will become a viscous circle. The freedom policy will be far more important than rate policy according to our policy analysis. 3.If the construction progress of wharfs can be in pace with the growth of enterprises, it will lower the interference between each other, reduce inefficient investment, and increase inter-stability. It¡¦s therefore the more accurate estimation of the growth of a harbor, the less disturbance effected by the other loops.
