Monoculture plantations of Pinus, Eucalyptus and Acacia have been established oil rainforest lands throughout the world. However, this type of reforestation generally supplies low quality timber and contributes to landscape simplification. Alternatives to exotic monoculture plantations are now beginning to gain momentum with farmers and landholders attempting to establish a variety of rainforest trees in small plantations. When compared to the well studied commercial species, knowledge concerning the growth and management of many of these rainforest species is in its infancy. To help expand this limited knowledge base an experimental plantation of 16 rainforest tree species in a randomised design was established near Mt. Mee, in south-eastern Queensland, Australia. Changes in growth, form (based on stem straightness, branch size and branchiness), crown diameters and leaf area of each species were examined over 5 years. Patterns of height growth were also measured monthly for 31 months. Species in this trial could be separated into three groups based on their overall growth after 5 years and their growth patterns. Early successional status, low timber density, high maximum photosynthetic rates and large total leaf areas were generally correlated to rapid height growth. Several species (including Araucaria cunninghamii, Elaeocarpus grandis, Flindersia brayleyana, Grevillea robusta and Khaya nyasica) had above average form and growth, while all species in the trial had considerable potential to have increased productivity through tree selection. As canopy closure occurred at the site between years four and five, growth increments declined. To reduce stand competition a number of different thinning techniques could be employed. However, simple geometric or productivity based thinnings appear to be inappropriate management techniques for this mixed species stand as they would either remove many of the best performing trees or nearly half the species in the trial. Alternatively, a form based thinning would maintain the site's diversity, increase the average form of the plantation and provide some productivity benefits.

In this study, we assessed whether contextual factors related to where or when an athlete is born influence their likelihood of playing professional sport. The birthplace and birth month of all American players in the National Hockey League, National Basketball Association, Major League Baseball, and Professional Golfer's Association, and all Canadian players in the National Hockey League were collected from official websites. Monte Carlo simulations were used to verify if the birthplace of these professional athletes deviated in any systematic way from the official census population distribution, and chi-square analyses were conducted to determine whether the players' birth months were evenly distributed throughout the year. Results showed a birthplace bias towards smaller cities, with professional athletes being over-represented in cities of less than 500,000 and under-represented in cities of 500,000 and over. A birth month/relative age effect (in the form of a distinct bias towards elite athletes being relatively older than their peers) was found for hockey and baseball but not for basketball and golf. Comparative analyses suggested that contextual factors associated with place of birth contribute more influentially to the achievement of an elite level of sport performance than does relative age and that these factors are essentially independent in their influences on expertise development.

Este estudo tem como objetivo identificar alguns fatores que têm contribuído para a evasão de adolescentes da Escola Dominical. O trabalho limita-se ao âmbito da Igreja Metodista, em cidades do interior do Estado de São Paulo. Entender a atual condição da adolescência é requisito para desenvolver ações capazes de prepará-la para o exercício da fé. O primeiro capítulo enfoca o desenvolvimento da adolescência.. Desde o início da Revolução Industrial pesquisadores, médicos, psicólogos, educadores entre outros têm se voltado à pesquisa desta fase de vida. O segundo capítulo propõe uma análise da Escola Dominical. O objetivo deste capítulo é compreender suas origens, seu relacionamento com a adolescência, sua estrutura e funcionamento, pois, ela é um dos melhores espaços para a formação do adolescente. Este precisa de um modelo educativo que ajude seu desenvolvimento e a Escola Dominical pode ser a agência educativa para garantir uma educação apropriada à época atual. O terceiro capítulo aprofunda o conceito de educação de modo geral e educação cristã de modo específico distinguindo-as de ensino. O modelo de educação necessário para o desenvolvimento do adolescente deve ser aquele que o ajude a elaborar seu próprio desenvolvimento numa prática contínua de elaboração e re-elaboração de sua educação, propiciando experiências de vida numa perspectiva cristã. Por fim, o quarto capítulo analisa o resultado da pesquisa de campo, a opinião do adolescente sobre a Escola Dominical e a partir desta compreensão identificar os fatores que contribuem para a evasão.

A dissertação teve como objetivo principal estudar como uma Instituição de Ensino Superior Privada (IES) atuante no Brasil tem crescido pós Lei de Diretrizes e Bases (LDB) de 1996 até 2015, por meio da análise do curso de bacharelado em Administração de Empresas, nas modalidades: presencial, EAD e Flex (semipresencial). Para este fim, foi realizada uma pesquisa exploratória, de caráter qualitativo baseada no método do estudo de caso. Para coleta de evidências foram analisados relatórios corporativos (Annual Report, Relatórios Internos e outros documentos), entrevistas baseadas em roteiro semiestruturado com gestores da IES privada e observações. Dentre os principais achados, verificou-se que as principais estratégicas de crescimento da IES privada estudada se basearam em fusões e aquisições de outras IES, abertura de novos polos de EAD, na abertura de novas unidades próprias, bem como em inovações em várias dimensões da organização. Os programas governamentais de financiamento aos alunos também são fortes contribuintes para este crescimento, como o Fundo de Financiamento ao Estudante do Ensino Superior (FIES) e o Programa Universidade para Todos (Prouni). Com essa nova realidade, o ensino superior privado recebeu incentivo e facilitação para o seu crescimento, a um ritmo acelerado. Consequentemente pode-se concluir que a IES privada estudada adotou as seguintes estratégias de crescimento: Expansão orgânica com fusões/ aquisições de Instituições menores, com desenvolvimento de planos para todos os campi Brasil; Greenfield (por meio de solicitação de autorização de novas unidades e/ou cursos) em cidades sem possibilidades de aquisições/fusões, e aumentando o número de vagas/ matriculas nas unidades já existentes, aderiu aos programas do governo e também cuidou da evasão por meio de: Seguro educacional; gestão preparada para atender necessidades do discente; Sistema de Ensino com currículos integrados nacionalmente; Intercâmbio de alunos e professores entre as diversas unidades em todas as regiões do país e padronização dos processos.

The burgeoning research into altruism and helping behaviour has examined the effect of many variables that enhance or inhibit helpfulness, but little attention has been given to the influence of culture. In the present research, data on various aspects of helping behaviour were collected in both the UK and the Sudan so that the importance of cultural influences could be investigated. In addition this research also tested the validity of current models of helping. In a repertory grid study, urgency and cost emerged as the main constructs people in the two countries use to distinguish between various helpful situations. A laboratory experiment designed to test existing models of intervention behaviour found significant main effects of country, group, size, cost and urgency; and a group size/urgency interaction. Subjects in the Sudan intervened faster than subjects in the UK; lone subjects intervened faster than subjects in small and large groups; subjects in low cost intervened faster than subjects in high cost conditions; and subjects in high urgency intervened faster than subjects in low urgency conditions. Group size effect was stronger in low than in high urgency conditions. Two field studies further investigated the effect of urgency and cost in urban-nonurban context. Significant main effects of urgency and cost were found in cities but not in towns; and people in cities were less helpful than people in towns. A questionnaire survey found that in both countries there were significant urban-nonurban differences in the incidence of reported social contacts and exchange of helpful acts between acquaintances, neighbours and strangers. However, there were no urban-nonurban differences between relatives and close friends. Finally, attitudes to altruism and helpfulness did not differ between the two countries or between urban and nonurban residents. The results highlight the need to incorporate urgency and cultural variables in theoretical models of helping behaviour.

While the city offers the potential of dynamic agglomeration economies which can spur the achievement of economic growth and act as an engine that powers the economy, it often appears as a centre of crisis in mature ‘developed’ regions and countries, even before the most recent economic downturn. This paper attempts to reconcile these two seemingly paradoxical observations by bringing in a strategic choice perspective to explain how concentrated strategic decision making in the corporate entities that dominate our cities has diminished the very diversity that Jacobs identified as being essential for cities to flourish and develop. The industrial policy implications for cities are subsequently explored in terms of building new industrial districts, developing high skill ecosystems, and fostering multinational webs of cities, all with the aim of ensuring the conditions exist in cities for creativity and development to flourish, notably a diverse and democratic economic system.

Rapid population increase and booming economic growth have caused a significant escalation in car ownership in many cities, leading to additional or, multiple traffic problems on congested roadways. The increase of automobiles is generating a significant amount of congestion and pollution in many cities. It has become necessary to find a solution to the ever worsening traffic problems in our cities. Building more roadways is nearly impossible due to the limitations of right-of-way in cities. Studies have shown that guideway transit could provide effective transportation and could stimulate land development. The Medium-Capacity Guideway Transit (MCGT) is one of the alternatives to solve this problem. The objective of this research was to better understand the characteristics of MCGT systems, to investigate the existing MCGT systems around the world and determine the main factors behind the planning of successful systems, and to develop a MCGT planning guide. The factors utilized in this study were determined and were analyzed using Excel. A MCGT Planning Guide was developed using Microsoft Visual Basic. ^ A MCGT was defined as a transit system whose capacity can carry up to 20,000 passengers per hour per direction (pphpd). The results shown that Light Rail Transit (LRT) is favored when peak hour demand is less than 13,000 pphpd. Automated People Mover (APM) is favored when the peak hour demand is more than 18,000 pphpd. APM systems could save up to three times the waiting time cost compared to that of the LRT. If comfort and convenience are important, then using an APM does make sense. However, if cost is the critical factor, then LRT will make more sense because it is reasonable service at a reasonable price. If travel time and safety (accident/crush) costs were included in calculating life-cycle “total” costs, the capital cost advantage of LRT disappeared and APM could become very competitive. The results also included a range of cost-performance criteria for MCGT systems that help planners, engineers, and decision-makers to select the most feasible system for their respective areas. ^
