Stand carrying capacity is the maximum size of population for a species under given environmental conditions. Site resources limit the maximum volume or biomass that can be sustained in forest stands. This study was aimed at estimating and determining the carrying capacity in loblolly pine. Maximum stand basal area (BA) that can be sustained over a long period of time can be regarded as a measure of carrying capacity. To quantify and project stand BA carrying capacity, one approach is to use the estimate from a fitted cumulative BA-age equation; another approach is to obtain BA estimates implied by maximum size-density relationships (MSDRs), denoted implied maximum stand BA. The efficacy of three diameter-based MSDR measures: Reineke's self-thinning rule, competition-density rule and Nilson's sparsity index, were evaluated. Estimates from three MSDR measures were compared with estimates from the Chapman-Richards (C-R) equation fitted to the maximum stand BA observed on plots from spacing trials. The spacing trials, established in the two physiographic regions (Piedmont and Coastal Plain), and at two different scales (operational and miniature) were examined and compared, which provides a sound empirical basis for evaluating potential carrying capacity. Results showed that the stands with high initial planting density approached the stand BA carrying capacity sooner than the stands with lower initial planting density. The maximum stand BA associated with planting density developed similarly at the two scales. The potential carrying capacity in the two physiographic regions was significantly different. The value of implied maximum stand BA converted from three diameter-based MSDR measures was similar to the maximum stand BA curve obtained from the C-R equation. Nilson's sparsity index was the most stable and reliable estimate of stand BA carrying capacity. The flexibility of Nilson's sparsity index can illustrate the effect of physiographic regions on stand BA carrying capacity. Because some uncontrollable factors on long-term operational experiments can make estimates of stand BA carrying capacity unreliable for loblolly pine, it is suggested that the stand BA carrying capacity could be estimated from high initial planting density stands in a relatively short period of time so that the risk of damages and the costs of experiments could be reduced. For estimating carrying capacity, another attractive option is to choose a miniature scale trial (microcosm) because it shortens the experiment time and reduces costs greatly. / Master of Science

The Best Medicine is an animated documentary that explores the true stories behind the live performances of stand-up comedians. The film juxtaposes live stand-up performances with candid interview footage combined with animation and illustration. Three subjects– Michael Burd, Casey Stoddard, and Jacob Kubon– discuss alcoholism, childhood abuse, and sexual anxiety, respectively. Their candid, intimate interviews reveal personal information, creating a new context with which to understand live stand-up comedy performance. This illustrates themes of finding humor in dark or painful circumstances and the cathartic nature writing and performance.

This is youth and adults education (EJA). The aim is to encourage student's participation in Portuguese classes, in public schools of the State of Rio de Janeiro (NEJA) assuming that the use of stand up comedy discursive genre would stimulate them to develop reading activities, textual production and reflection on linguistic uses, focusing on the study and use of anaphoric direct object. For this purpose, this research was based on Collaborative Learning Theory (BEHRENS, 2013), which enabled the organicity of mediation in order to promote a participatory education in which the interaction between student and teacher is the basis of the work. In addition, in linguistic theories we searched assumptions to justify the proposal. Namely: Referencing Theory (KOCH and ELIAS, 2012; CHAN, 2004) and the continuous variation of Linguistics (BORTONI-RICARDO, 2004, 2005), with emphasis on continuous orality-literacy. The first one allowed the understanding of anaphoric relations, especially the Anaphoric Direct Objetc one, in a text; the second one enabled the recognition that linguistic accomplishments, variables, such as those in this category, are in a continuous line rather than on opposite sides. We also keep this continuous association with the discursive genres continuous proposed by Marcuschi (2001). This work also aimed to achieve specific objectives in Portuguese classes just as teaching referral strategies in acusativess forms, as well as other more general like promoting discussion, the collectivity, the sharing of ideas and mutual respect between teacher and students. / Este trabalho tem por objetivo desenvolver uma media??o did?tica, de base colaborativa, para estudo e uso do objeto direto anaf?rico (ODA), a partir do g?nero discursivo stand-up comedy, em turmas de educa??o para jovens e adultos que n?o deram continuidade aos estudos e para os que n?o ingressaram no Ensino Fundamental e/ou M?dio com a idade apropriada. Trata-se do segmento Educa??o de Jovens e Adultos (EJA). Busca-se incentivar a participa??o, nas aulas de L?ngua Portuguesa, dos alunos inseridos nos cursos da Educa??o de Jovens e Adultos da rede p?blica do estado do Rio de Janeiro (NEJA), partindo-se da hip?tese de que o uso do referido g?nero os estimularia a desenvolver atividades de leitura, produ??o textual e reflex?o sobre usos lingu?sticos, com foco no estudo e uso do ODA. Para tanto, esta pesquisa baseou-se na Teoria Colaborativa de Aprendizagem (BEHRENS, 2013), que possibilitou a organicidade da media??o para promovermos um ensino participativo em que a intera??o entre aluno e professor constitui a base do trabalho. Al?m disso, buscamos, em teorias lingu?sticas, pressupostos para fundamenta??o da proposta. A saber: a teoria da Referencia??o (KOCH E ELIAS, 2012; CAVALCANTE, 2004) e a dos Cont?nuos de varia??o lingu?stica (BORTONI-RICARDO, 2004, 2005), com ?nfase no cont?nuo oralidade-letramento. A primeira permitiu o entendimento das rela??es anaf?ricas, sobretudo a do ODA, em um texto; a segunda possibilitou o reconhecimento de que as realiza??es lingu?sticas, as vari?veis, como as dessa categoria, situam-se em uma linha cont?nua e n?o em lados opostos. Procedemos ainda ? associa??o desse cont?nuo com o cont?nuo dos g?neros discursivos proposto por Marcuschi (2001). Este trabalho buscou, ainda, atingir objetivos espec?ficos da disciplina de L?ngua Portuguesa, como ensinar estrat?gias de referencia??o em formas acusativas, al?m de outros mais gerais, como promover o debate, a coletividade, o compartilhamento de ideias e o respeito m?tuo entre professor e alunos.

Indiana University-Purdue University Indianapolis (IUPUI) / Before the “sick” comedians arrived onto the comedy landscape political and culturally based humor was considered taboo, but the 1950s witnessed a dramatic transformation to the art of stand-up comedy. The young comedians, including Lenny Bruce and Mort Sahl, became critical of American Cold War policies and the McCarthyistic culture that loomed over the nation’s society. The new stand-up comics tapped into a growing subculture of beatniks and the younger generation at large that rebelled against the conservative ideals that dominated the early post-war decade by performing politically and socially laced commentary on stage in venues that these groups frequented. The two comedians that best represent this comedic era are Jewish comics Mort Sahl and Lenny Bruce. Their comedy was more politically oriented than the other “sick” comics, and they started an entertainment revolution with their new style. They became legendary by challenging the status quo during a historically conservative time, and inspired numerous comics to take the stage and question basic Cold War assumptions about race, gender, and communism.

Les résultats de récentes études supportent l’idée que la perception de la force aurait un rôle important dans la réalisation des tâches fonctionnelles telles que le passage assis à debout (PAD). Cependant, très peu d’études se sont attardées à quantifier la précision avec laquelle les individus en santé sont capables de percevoir la force musculaire. De plus, aucune étude n’a évalué la perception de la distribution du poids lors du PAD chez la clientèle saine. L’objectif principal était de recueillir des données sur la capacité des individus en santé, jeunes et âgés, à percevoir la force musculaire lors d’une contraction statique des extenseurs du genou et à percevoir la distribution du poids (DP) lorsqu’ils réalisent le passage assis à debout. Cette étude a été effectuée auprès de 31 individus, divisés en deux groupes d’âge (< 50 ans et > 60 ans). Les résultats du premier objectif visant à quantifier les erreurs de perception de la force lors d’une contraction statique des extenseurs du genou ont démontré que les erreurs absolues et brutes sont plus élevées pour les niveaux de force supérieurs à 50 % CVM et que les erreurs brutes sont plus importantes chez les jeunes pour les hauts niveaux de force. Les résultats du second objectif visant à évaluer l’effet de différentes références sensorimotrices sur les erreurs de perception de la force musculaire ont montré qu’une référence à 50 % CVM préalablement montrée au participant et qu’une contraction simultanée des muscles de la préhension de la main diminuent les erreurs brutes et absolues de perception pour le niveau de force 70%. Les résultats du troisième objectif visant à quantifier les erreurs de perception de la DP lors du PAD ont démontré que les sujets jeunes et âgés ont une bonne capacité à percevoir leur DP avec des erreurs absolues et brutes variant respectivement entre 2,9 % et 9,4 % et entre -5,7 % et 5,7 % et des coefficients de corrélations intra-classes supérieurs à 0,75 entre la DP produite et celle perçue. Les résultats contribuent à approfondir les connaissances relatives à la perception de la force et de la DP chez les individus en santé. Ces données pourront servir à titre comparatif lors d’études menées auprès des patients hémiparétiques afin d’évaluer s’ils ont des problèmes perceptifs pouvant expliquer l’asymétrie récurrente qu’ils présentent dans leurs tâches fonctionnelles. / Results of recent studies support the idea that perception of force would have an important role in performing functional tasks such as sit-to-stand (STS). However, very few studies have focused on the quantification of the accuracy with which healthy individuals are able to perceive muscular force. Furthermore, no study has assessed the perception of weight-bearing distribution during the STS in healthy individuals. The purpose of this study was to provide evidence on the capacity to perceive muscular force and weight-bearing distribution in simple and complex tasks in healthy individuals. This study was conducted with 31 individuals, divided into two main age groups (<50 years > 60 years). Its first objective was to quantify the errors in perception of force during a static contraction of knee extensors and to compare these errors between young and elderly groups. Results showed that the absolute and raw errors are greater for force levels higher than 50% of maximum voluntary contraction (MVC) and that raw errors are greater in young participants for high force levels. This study’s second objective was to assess the effect of different sensorimotor references on the magnitude of errors of force perception. The results showed that a reference of 50% MVC presented to the participant beforehand or a simultaneous contraction of hand grip muscles reduced the raw and absolute errors of perception at the level of 70% MVC. A third objective was to quantify the errors of perception of weight-bearing distribution during STS and to measure the effect of age on these errors. The results showed that younger and elderly participants have an ability to perceive their weight-bearing distribution with absolute and raw errors varying respectively from 2.9% to 9.4% and from -5.7% to 5.7%. The intra-class correlation coefficient was higher than 0.75 between the weight-bearing distribution produced and that perceived during STS. The results contribute to extend knowledge about perception of force and weight bearing distribution in young and elderly healthy individuals. This data will be used for comparison in studies conducted with hemiparetic individuals in order to assess if the latter have perceptual problems which may explain the recurrent asymmetry they present in functional tasks.

A growing interest in using forest biomass for bioenergy generation may stimulate intensive harvesting scenarios in Germany. We calculated and compared nutrient exports of conventional stem only (SO), whole tree without needles (WT excl. needles), and whole tree (WT) harvesting in two medium aged Norway spruce (Picea abies L. Karst.) and Scots pine (Pinus sylvestris L.) stands differing in productivity, and related them to soil nutrient pools and fluxes at the study sites. We established allometric biomass functions for each aboveground tree compartment and analyzed their nutrient contents. We analyzed soil nutrient stocks, estimated weathering rates, and obtained deposition and seepage data from nearby Level II stations. WT (excl. needles) and WT treatments cause nutrient losses 1.5 to 3.6 times higher than SO, while the biomass gain is only 1.18 to 1.25 in case of WT (excl. needles) and 1.28 to 1.30 in case of WT in the pine and spruce stand, respectively. Within the investigated 25-year period, WT harvesting would cause exports of N, K+, Ca2+, and Mg2+ of 6.6, 8.8, 5.4, and 0.8 kg·ha−1 in the pine stand and 13.9, 7.0, 10.6, and 1.8 kg·ha−1 in the spruce stand annually. The relative impact of WT and WT (excl. needles) on the nutrient balance is similar in the pine and spruce stands, despite differences in stand productivities, and thus the absolute amount of nutrients removed. In addition to the impact of intensive harvesting, both sites are characterized by high seepage losses of base cations, further impairing the nutrient budget. While intensive biomass extraction causes detrimental effects on many key soil ecological properties, our calculations may serve to implement measures to improve the nutrient balance in forested ecosystems.
