Creators: name: Araújo, Marcos Vinícius
Publisher: name: Post-ip: Revista do Fórum Internacional de Estudos em Música e Dança
Year: 2019

description: O presente trabalho apresenta o estado da arte da pesquisa em andamento que investiga a função de comportamentos autorreguladores da prática musical eficiente na experiência de fluxo, uma sensação holística de engajamento intenso na prática musical. Os resultados preliminares da presente investigação sugeriram que o estado psicológico de fluxo, na área da performance musical, é uma experiência multifacetada, com características cognitivas, comportamentais, afetivas e fisiológicas, as quais podem exercer influências positivas no desempenho de atividades musicais distintas. Apesar de participantes da presente pesquisa terem reportado viver a experiência do estado de fluxo durante os seus processos individuais de prática musical, algumas de suas características foram significativamente menos reportadas. São apresentadas algumas implicações para a área da performance musical e sugestões para pesquisas futuras.

description: Este estudo analisa a criatividade envolvida na performance da obra Water Music, de Tan Dun. Através da identificação de quatro pontos-chave da obra, verificou-se as relações destes com a criatividade para compreender as influências da interferência criativa do intérprete na performance. Conclusões demonstraram que o músico não pode se isentar da tarefa de criar que lhe é imposta e que seu engajamento criativo tem grande influência no caráter da interpretação, configurando, assim, uma construção criativa e colaborativa entre compositor e intérprete.

description: As robots venture into the real world, they are subject to unmodeled dynamics and disturbances. Traditional model-based control approaches have been proven successful in relatively static and known operating environments. However, when an accurate model of the robot is not available, model-based design can lead to suboptimal and even unsafe behaviour. In this work, we propose a method that bridges the model-reality gap and enables the application of model-based approaches even if dynamic uncertainties are present. In particular, we present a learning-based model reference adaptation approach that makes a robot system, with possibly uncertain dynamics, behave as a predefined reference model. In turn, the reference model can be used for model-based controller design. In contrast to typical model reference adaptation control approaches, we leverage the representative power of neural networks to capture highly nonlinear dynamics uncertainties and guarantee stability by encoding a certifying Lipschitz condition in the architectural design of a special type of neural network called the Lipschitz network. Our approach applies to a general class of nonlinear control-affine systems even when our prior knowledge about the true robot system is limited. We demonstrate our approach in flying inverted pendulum experiments, where an off-the-shelf quadrotor is challenged to balance an inverted pendulum while hovering or tracking circular trajectories.
Discursos polifónicos na obra de Luciano Berio (1925-2003): o conceito de amálgama do timbre na análise e interpretação da Sequenza V

description: O presente artigo tem como objetivo analisar a Sequenza V do compositor Luciano Berio, com foco na sua interpretação. A análise propõe uma discussão sobre a transformação sonora que resulta de um jogo polifónico de caráter multifónico, baseado fundamentalmente no timbre. Com este trabalho, procura-se contribuir para a fomentação de referências da área, especialmente sobre aspectos interpretativos concernentes ao repertório contemporâneo. Como metodologia, recorreu-se à pesquisa bibliográfica, à análise musical e ao estudo prático e construção performativa da obra ao trombone. O processo de preparação e estudo da obra no trombone seguiu as quatro dimensões de análise propostas pelo compositor - temporal, tonal, dinâmica e morfológica - e que estão expressas numa entrevista publicada em 1980. Esta pesquisa procura mostrar ainda como a ideia de polifonia latente se expressa na Sequenza V e como se intensifica progressivamente ao longo da obra.

description: We analyze all possible symmetry reductions of Lagrangians that yield fully equivalent field equations for any 4-dimensional metric theory of gravity. Specifically, we present a complete list of infinitesimal group actions obeying the principle of symmetric criticality, identify the corresponding invariant metrics (and $l$-chains), discuss relations among them, and analyze simplifications allowed by the residual diffeomorphism group and Noether identities before and after variation of the reduced Lagrangian. We employ rigorous treatment of the symmetry reduction by Fels and Torre and use the Hicks classification of infinitesimal group actions by means of Lie algebras pairs of isometries and their isotropy subalgebras. The classification is recast in the coordinates in which the well-known symmetries and geometries are easily recognizable and relatable to each other. The paper is accompanied by a code for the symmetry reduction of Lagrangians that we developed in \texttt{xAct} package of \textsc{Mathematica}.

title: Effects of Polyacrylamide on Rangeland Soils and Plants
Creators: name: Al-Rowaily, Saud Leily R.
Publisher: name: Utah State University
Year: 1992

description: The objectives of this study were to determine the effects of two forms of polyacrylamide (PAM) conditioners (Cross-linked and Non-cross-linked PAM) on evaporation, saturated hydraulic conductivity, water retention, crust and crack formation of soils, seed germination, and seedling and tubeling growth.
The two PAM conditioners, 0.2% concentration by weight, were mixed with seven soils of different textures (sandy loam, silt, silty clay loam, silt loam, fine sand, medium sand, and coarse sand) to investigate the effects on evaporation, saturated hydraulic conductivity, and water retention. Soil samples of different textures were brought to field capacity and placed in a growth chamber for two weeks to measure evaporation under a controlled environment.
A second experiment was carried out in the field to determine the effects of the two PAM conditioners on seedling emergence of crested wheatgrass, Agropyron desertorum, as well as on soil cracking, penetrometer resistance, and soil moisture. The two PAMs were mixed with a silt loam Xerollic Calciorthid at 0.2% concentration by weight. Seedling emergence was monitored directly for two weeks. Soil moisture was measured by TDR. Cracking was described by photographic means. Penetrometer resistance was measured by a hand-held. penetrometer.
The third experiment was also carried out in the field, using the same soil texture as in experiment 2, to investigate the effects of the two PAMs on soil moisture at depths between 25 to 45 cm and on sagebrush (Artemisia tridentata) growth.
Evaporation was found to be significantly lower in the fine-textured controls than under the two PAM treatments. The sandy loam and sandy soils experienced significantly higher evaporation from the controls. The two PAM conditioners significantly reduced saturated hydraulic conductivity on all soil textures. Water retention increased in the PAM-treated textures at the matric potential range used (0.0, 0.05, 0.1, 1.5 MPa) • The PAM application also did not improve grass seedling emergence or improve soil moisture, and did not have any significant affects on sagebrush growth. Larger cracks were found in the two plots treated with PAM than the controls. Lower penetrometer resistance occurred in the two PAM treatments compared to the untreated control.
From this study, it can be concluded that the application of PAM conditioners, at relatively high concentrations used, could be more viable on sandy textures. Other researchers are advised to try lower application rates than used here, particularly with finer textured soils.
The effect of twist on flexible hydrofoils
Creators: name: Milne, John Gordon
Publisher: name: University of British Columbia
Year: 2010

description: Flexible low aspect ratio hydrofoils were tested to investigate the effect of twist on the lift and drag characteristics and in particular, the high induced drag force. Flexible models with stiffeners at various positions and rigid models with a set twist were tested in a water flume and the lift and drag forces were measured over a range of angles of attack. It was confirmed that twisting can be used as an alternative to tapering to produce elliptic loading. Twisting of tapered wings was shown to be beneficial in the cases tested and the benefits are in contradiction to the simple theory of elliptic loading. It was found that twisting is more beneficial than the simple theory shows and that the twisted wing is less sensitive to changes in angle of attack.

description: Para a etnomusicóloga Helen Myers “o trabalho de campo é a tarefa mais pessoal e necessária exigida a um etnomusicólogo” (1992: 21). Consiste em “estar no mundo” como refere Jeff Titon (2008: 31) e promove uma experiência vivida no contato com indivíduos como um meio privilegiado para a aprendizagem sobre uma determinada prática musical (Barz e Cooley 2008). Foi este posicionamento que orientou o trabalho de campo que realizei entre 2012 e 2013, durante o estudo que venho a desenvolver sobre a prática dos bombos em Lavacolhos. Esta prática presente em três festas locais, integra tocadores – homens –, coro masculino, artesãos, comunidade de Lavacolhos – residentes fora da localidade – envolve a igreja e a autarquia. Esta complexidade conduziu à formulação de um conjunto de questões como: em que consiste a performance dos bombos em Lavacolhos, quem são os intervenientes, quais as dimensões icônicas dos seus instrumentos musicais e quais os jogos de poder que circunstanciam. Neste artigo pretendo abordar questões relacionadas com os desafios e as especificidades que constituíram o estar em campo durante a minha pesquisa em Lavacolhos, refletir aspectos como as questões de gênero, a reformulação de papéis sociais e a interferência da autarquia e da igreja na prática dos bombos.

Inland by sea! : The mystery of emotion and creative praxis
Creators: name: Reeve, VG
Publisher: name: University Of Tasmania
Year: 2023

description: This creative writing thesis explores narrative emotion and reader engagement and comprises a novella, Inland by Sea!‚ÄövÑvp, and critical exegesis. The novella develops its creative praxis around the role of emotion in establishing reader engagement through perspective-taking. Inland by Sea!‚ÄövÑvp tells the story of a continent settled by pirates during the middle ages and, in so doing, offers an allegory for Australian settlement and colonialism more broadly. With its protagonist, Robbie, involved in a quest for a house hidden at the centre of the continent, supposed to contain untold riches, Inland by Sea!‚ÄövÑvp addresses the motivations behind colonial settlement and the effect of such endeavours upon local populations. Narratives engage readers in the cooperative discourse of reading through the interplay of perspectives, which the reader must negotiate in order to understand the story. Every instance of perspective-taking will involve the reader in appraisals of feeling, suggesting that reading, and the social and cultural experiences that underpin it, is always a matter of feeling. Our social and cultural constructions form bases of knowledge about possible perspectives, enabling us to comprehend experiences that we are unlikely to encounter directly. Perspectivetaking is thus a cognitive process that has the capacity to affect us through invocations of remembered feeling (about things that happened or were merely imagined) resituated in respect to newly imagined positions, but also through the somatic effects of reading itself. Drawing on critical work about emotion, cognition, and the role of perspective-taking, the exegesis speaks directly to the creative practice developed in Inland by Sea!‚ÄövÑvp Arguing that, the reader, through the recursive intimacies of multiple perspectives, rubbing up together, sometimes nested, one within the other (a character, for example, seeing herself through another's eyes; the narrative voice seeing what she sees as well as seeing what the other actually sees, etc.), is called upon, in the marshalling of their recollections, to take up these diverse stances in respect to identified correspondences. Thus, through the process of recursive perspective-taking, the emotional meanings of the text come to further inform the emotional meanings of the reader's personal experience. It is by this means that Inland by Sea!‚ÄövÑvp, through its allegorical relation to myths of Australian settlement, challenges readers to take on new perspectives of Australian history and culture.
title: Growth and Water Relations of Mountain Big Sagebrush on Reclaimed Mine Soils in Southwestern Wyoming
Creators: name: Carpenter, Alan T.
Publisher: name: Utah State University
Year: 1985

description: Mined-land reclamation practices in shrub-steppe ecosystems can be augmented by planting seedlings of locally dominant shrubs, e.g., mountain big sagebrush. Dispersion pattern could affect sagebrush performance by influencing amounts of windborne snow, soil and litter which accumulate around shrubs and by influencing water withdrawal by roots. Mountain big sagebrush seedlings were planted in plots on a reclaimed coal strip mine in two dispersion patterns: singly and in clumps of four at the same overall density. Performance of mountain big sagebrush was monitored during two growing seasons. Measures included plant survival, end-of-growing season aboveground biomass, leaf water potential components, soil water potential, twig and ephemeral leaf survival and reproductive allocation. Most measures of performance were similar for single and clumped plants. However, single plants had a greater twig elongation rate than clumped plants, and roots of plants in clumps removed less soil water to 50 cm than roots of single plants. In order for shrub dispersion pattern to affect plant performance via differential snow, soil or litter accumulation, the plants would have to respond to the added resources, probably water and nitrogen. An experiment was conducted to test if a small extra increment of water and nitrogen would affect mountain big sagebrush plants. The same plant performance indices listed above were monitored. The added water and nitrogen, either alone or in combination, had no effect except on reproduction. In 1983, there was a significant water* fertilizer interaction observed for some of the reproductive metrics, while in 1984 there was a significant water effect. While a significant main effect of nitrogen was expected under the prevailing wet conditions, the large reservoir of soil nitrogen evidently provided sufficient nitrogen. Reproduction was more sensitive to added water and nitrogen resources than was vegetative growth. The nearly equal performance of mountain big sagebrush in the two dispersion patterns may have resulted from several factors. Water availability to the experimental shrubs was very high throughout the study due to abnormally heavy precipitation and to removal of weeds from the plots. During drier years, dispersion pattern may have greater influence on the shrubs.

description: Este estudo centra-se na Festa de São Brás dos Montes que se realiza anualmente no mês de Fevereiro no lugar dos Montes, no distrito da Guarda. Neste evento diversas “maltas” (grupos organizados de tocadores de bombos, caixas, flautas, acordeões e concertinas), oriundas de aldeias à volta da serra, entregam-se a um ritual marcado tanto pela tradição como pela reinvenção. A pesquisa assenta no trabalho de campo realizado junto de uma das “maltas”, ao longo de 2008, tendo acompanhado o processo de construção e arranjo dos membranofones e flautas. À luz das propostas de Victor Turner (2009), o estudo compreende o papel aglutinador do ritual em que, ano após ano, se repetem as mesmas práticas de excesso colectivo. Este estudo tem como objectivo dar a conhecer uma prática não documentada pela etnografia portuguesa e discutir o papel da música no processo de reactualização de tradições. Nesta prática, o conflito latente e a sua resolução no equilíbrio dos poderes que gera, pode ajudar-nos a entender a forma como estes homens se relacionam, dentro e fora do contexto do evento. A música permite integrar os processos de mudança e adapta-se aos tempos modernos globalizados, sendo este processo de adaptação essencial à sua própria sobrevivência.

description: Focusing on hybrid diffusion dynamics involving continuous dynamics as well as discrete events, this article investigates the explicit approximations for nonlinear switching diffusion systems modulated by a Markov chain. Different kinds of easily implementable explicit schemes have been proposed to approximate the dynamical behaviors of switching diffusion systems with local Lipschitz continuous drift and diffusion coefficients in both finite and infinite intervals. Without additional restriction conditions except those which guarantee the exact solutions posses their dynamical properties, the numerical solutions converge strongly to the exact solutions in finite horizon, moreover, realize the approximation of long-time dynamical properties including the moment boundedness, stability and ergodicity. Some simulations and examples are provided to support the theoretical results and demonstrate the validity of the approach.

Does the 5 factor personality model predict engagement with, and response to, direct-to- consumer genetic testing?
Creators: name: Pearce, IA
Publisher: name: University Of Tasmania
Year: 2023

description: Recently, the use of genetic testing to determine an individual's predisposition to psychological disorders has increased. Direct-to-consumer (DTC) genetic testing now enables individuals to order and receive genetic information directly. We explored the effects of personality traits (using the 5-factor model) on attitudes and emotional response towards DTC testing, intentions to seek medical advice, and intentions of behavioural change. A total of 177 participants completed the online survey (males; 26; females; 148, other; 3; between 18 and 68 years of age, M =32.20, SD =14.94). Hypothesis 1 was not supported as opennessto-experience and conscientiousness were not positively associated with attitudes, although extraversion and neuroticism were positively associated. Hypothesis 2 was not supported as neuroticism and conscientiousness were not positively associated with emotional responses. Contrary to hypothesis 3, conscientiousness and agreeableness did not predict intention to seek medical advice, however neuroticism was a significant predictor. Hypothesis 4 was not supported as no personality traits predicted intention to make behavioural changes. This is the first study to investigate this area, and the results suggest that neuroticism and extraversion are significant predictors of individuals' attitudes and response to direct-to-consumer genetic testing for psychological disorders.

description: Neste artigo procuro apresentar uma primeira formulação de um conceito que começo por nomear como ‘monólogo interior instrumental’ e que, no final, acabo por designar “música do pensamento” (Steiner 2012). Trata-se de um conceito que, como pianista/compositora, aplico a uma trilogia de solos meus e que pode ser enquadrado no contexto do teatro instrumental, pelas diversas utilizações de recursos extra-musicais que faz. Para este conceito são ainda importantes a concepção de teatro de Artaud e algumas questões colocadas por Georg Steiner no seu livro “Poesia do Pensamento – Do Helenismo a Celan”.

description: Human-centered artificial intelligence (AI) posits that machine learning and AI should be developed and applied in a socially aware way. In this article, we argue that qualitative analysis (QA) can be a valuable tool in this process, supplementing, informing, and extending the possibilities of AI models. We show this by describing how QA can be integrated in the current prediction paradigm of AI, assisting scientists in the process of selecting data, variables, and model architectures. Furthermore, we argue that QA can be a part of novel paradigms towards Human Centered AI. QA can support scientists and practitioners in practical problem solving and situated model development. It can also promote participatory design approaches, reveal understudied and emerging issues in AI systems, and assist policy making.

description: Este trabalho apresenta os resultados de uma pesquisa etnomusicológica sobre o zambê da família Cosme, em Tibau do Sul, no estado do Rio Grande do Norte (RN), nordeste do Brasil. A economia local é mantida pela produção açucareira, carcinicultura e pelo turismo. No que diz respeito a expressões musicais, são emblemáticos o coco de roda e, sobretudo, o zambê - tipo de música/dança coletiva, da tradição oral, com canto responsorial e acompanhamento percussivo, praticado por afrodescendentes no RN. Esta investigação tem como objetivo apresentar e discutir a performance do zambê da família Cosme, principalmente, no que se refere a características estruturais, ao universo simbólico e à espetacularização. O processo investigativo contemplou observação participante, análises de materiais audiovisuais e da história oral. Verificou-se que o zambê mostra similaridades na forma poética (canto responsorial) com tipos de “coco”, contudo apresenta peculiaridades na dança, na instrumentação, nos seus usos e funções (Merriam 1964). O zambê no RN tem sido noticiado, desde a primeira década do século XX, por historiadores, pesquisadores, produtores culturais etc., o que tem rendido registros literários e audiovisuais. Na respectiva localidade, o grupo não brinca corriqueiramente, atende hoje basicamente à demanda externa, ainda que efêmera, através de apresentações pagas - isso, segundo afirmam, contribui para a manutenção do zambê.

title: The Effects of Disease, Prey Fluctuation, and Clear-Cutting on American Marten in Newfoundland, Canada
Creators: name: Fredrickson, Richard J.
Publisher: name: Utah State University
Year: 1990

description: Individual variation in survival and behavior of American marten (Martes americana) was studied in relation to disease, prey fluctuation, and clear-cutting from 10 January 1986 through 20 August 1987 in Newfoundland, Canada. Thirty-seven of forty marten captured on the study area were telemetered and monitored for part or all of the study.
Marten mortality was concentrated in two intervals, fall 1986 and late winter 1987. Mortality during fall 1986 was attributable to encephalitis, while marten deaths during late winter 1987 resulted from predation and starvation attributable to the prey decline. Nonsuppurative encephalitis was first detected 7 October 1986; no further evidence of the disease could be found after 1 November 1986. In early October 1986, declining populations of meadow voles were documented; by June 1987 no voles could be found on the study area.
In both mortality periods, young-of-the-year marten had lower survival rates than older marten, and transients survived less well than residents. However, encephalitis appeared to be a less selective mortality agent than the prey decline. Females, considered to be more vulnerable to resource perturbations, had lower survival rates and males higher rates during late winter 1987 than during the disease epizootic.
Clear-cutting operations ran from 4 August 1986 through 14 November 1986; 3% (259 ha) of the study area was cut. Marten of all ages avoided clear-cuts during logging operations and for the first nine months afterward. Resident kits made significantly greater use of clear-cuts than older residents and were 3.2 times more likely than older residents to be found within clear-cuts. However, resident kits were 2.6 times and adults 8.3 times more likely to use habitats other than clear-cuts.
The decline in prey abundance resulted in several changes in marten movement and spacing behaviors. Intrasexual home range overlap by residents was eliminated. All female residents present before the prey decline either died or abandoned their home ranges. The ratio of transients to resident numbers increased. Recolonization of vacated habitats was slower, and duration of dispersal for females increased. Intruder pressure and mating access appeared to play little role in the observed changes in social spacing. The decline in marten numbers during and after the prey decline appeared to have been partially affected by changes in spacing behaviors.
First evidence of a collision between two unrelated open clusters in the Milky Way

description: We report the first evidence of an on-going collision between two star clusters in our Galaxy, namely IC 4665 and Collinder 350. These are open clusters located at a distance of ~330 pc from the Sun and ~100 pc above the Galactic plane, and they both have prograde motions with only a small difference in their velocities (Collinder 350 moves ~5 km/s faster than IC 4665); as inferred from ESA/Gaia based catalogue. Interestingly, the two clusters are physically separated by only 36 pc in space; a distance that is smaller than the sum of their respective radii. Furthermore, the clusters exhibit signatures of elongated stellar density distributions, and we also detect an onset of an inter-cluster stellar bridge. Moreover, the orbit analysis suggests that the younger cluster IC 4665 (age=53 Myr) must have formed at a distance > 500 pc away from Collinder 350 (age=617 Myr). These findings together imply that the two clusters do not represent merging of two objects in a binary system, rather, what we are witnessing is an actual collision between two independently formed star clusters. This collision phenomenon provides a unique opportunity to explore new aspects of formation and evolution theory of star clusters.

description: After introducing non-minimal variables, the midpoint insertion of Y\bar Y in cubic open Neveu-Schwarz string field theory can be replaced with an operator N_ρdepending on a constant parameter ρ. As in cubic open superstring field theory using the pure spinor formalism, the operator N_ρis invertible and is equal to 1 up to a BRST-trivial quantity. So unlike the linearized equation of motion Y\bar Y QV=0 which requires truncation of the Hilbert space in order to imply QV=0, the linearized equation N_ρQV=0 directly implies QV=0.

title: The Acarau Valley in Northeast Brazil: Vegetation, Soils and Land Use.
Creators: name: Queiroz, Joao Stacishin de
Publisher: name: Utah State University
Year: 1985

description: The purpose of this study was to describe and characterize the principal kinds of land in the mid-portion of the Acarau Valley, Ceara State, Northeast Brazil. The specific aims were: (1) to develop a specific-purpose soil classification; (2) to investigate vegetation-environment relationships; (3) to develop hypotheses about short-term vegetation dynamics; and (4) to evaluate the usefulness of computer processed multispectral-scanner (MSS) data for mapping rangeland resources in Northeast Brazil. Fifty-one soil profiles were described and ocular estimates of vegetation cover by species were made at each subjectively selected site. Two Landsat scenes were used to assess the usefulness of MSS data for mapping rangelands. A specific-purpose soil classification was intuitively derived from field experience and tested with a clustering algorithm, itself validated with profiles from independently conducted soil surveys. Detrended correspondence analysis was used to ordinate vegetation stands. Computer-processed MSS data subjected to a maximum-likelihood classifier generated a map of spectral classes, which was compared xvii with delineations of a conventionally produced soils map. Cluster analysis of profiles from the independently conducted soil surveys produced three distinct clusters: soils with a reddish argillic horizon, soils with clay-pan and soils lacking pedogenic horizons. Values of selected chemical and physical parameters for each cluster were concentrated in relatively narrow ranges, which corroborated the practical validity of the clustering algorithm. Clustering of soils from the study area produced similar results. Close agreement between cluster composition and grouping of soils by the specific-purpose classification validated the intuitively derived soi1 classes. Slash-and-burn cultivation results in the replacement of late-seral fire-sensitive species such as Auxemma oncocalyx, Mimosa caesalpiniaefolia and Caesalpinia pyramidalis by fire-tolerant early-seral species such as Croton hemiargyreus and Mimosa acutistipula. Impeded drainage restricts the growth of important woody species and gives rise to sparcely wooded surfaces. The areal distribution of computer-generated spectral classes and soils map delineations revealed considerable disagreement. This was attributed to the large proportion of boundary pixels associated with small soil-vegetation units.

description: Durante o trabalho de campo para doutoramento, que tenho vindo a desenvolver desde 2010, com a comunidade goesa da Catembe (Moçambique), a fotografia revelou-se um elemento importante na investigação enquanto mediadora na minha relação com os colaboradores e na compreensão de questões muitas vezes omissas no discurso oral. A partir da fotografia e da sua visualização alguns dos colaboradores iniciaram as descrições sobre as práticas musicais, as festas e os rituais nos quais participam ou participaram no passado. Assim, a fotografia preparou o cenário para a narrativa na qual a música que não se ouvia de alguma forma, mas se tornou real, a partir da evocação de memórias pessoais sugeridas pela imagem. A fotografia, enquanto documento de registo etnográfico, tem sido amplamente discutida sobretudo no quadro da antropologia. No início do século XX Malinowski (1961) e Lévi-Strauss (2004) abrem caminho para que a antropologia incorporasse a fotografia como elemento de análise e como forma de complementar a narrativa etnográfica. Ana Caetano (2007; 2008a; 2008b) refere a utilização da fotografia enquanto instrumento com valor emocional, capaz de criar recordações de algo considerado significativo como marca de identidade pessoal ou colectiva. Porém, a relação da fotografia com a música parece ser ainda um aspeto pouco estudado, talvez pela aparente contradição entre a relação que ambas estabelecem com a noção de tempo: a música acontece no tempo de uma forma dinâmica enquanto a fotografia congela o tempo em que acontece estatizando-o. Neste trabalho, pretendo mostrar de que forma o recurso à fotografia pode ajudar a mapear e a reconstruir práticas musicais revertendo a aparente estaticidade do tempo instantâneo que representa, a partir dos testemunhos e da minha observação dos goeses residentes na Catembe.

title: Visitor Characteristics and Attitudes Toward Policies in the Irish Wilderness of Southern Missouri
Creators: name: Bumpus, Debra Lynn
Publisher: name: Utah State University
Year: 1990

description: Questionnaires which assessed attitudes toward wilderness policies and behavioral norms were distributed to individuals at the Irish Wilderness, in the surrounding communities, and to conservation groups. Questions were designed to describe general wilderness policies and also those policies specific to the Irish Wilderness. The Irish Wilderness, located in southeastern Missouri, was designated as a national wilderness area in 1984. Prior to this 1986 study, no previous studies had been conducted in the area to describe visitor characteristics and attitudes toward wilderness management policies. A comparison was also made between the attitudes of the Irish Wilderness visitor and of Pacific Northwest wilderness visitors (Hendee et al., 1968).
Three hypotheses were tested: (1) differences exist between experienced and nonexperienced individuals in their perception of what constitutes wilderness norms as defined by the 1964 Wilderness Act, (2) differences do not exist between western and midwestern wilderness visitors and their attitudes toward proper wilderness behavior and norms, and (3) individuals with prior Irish Wilderness visits will exhibit a more purist attitude toward administrative goals set for the Irish Wilderness than those individuals with less wilderness experience.
The findings of this study show that visitors with the most wilderness experience respond more favorably to statements which reflect the ideals and goals of the 1964 Wilderness Act. This corresponds with information provided in Young's (1982) study which stated that the experienced visitor would exhibit a more purist attitude in regards to wilderness behavior. Also, respondents from the Irish Wilderness study differed from the respondents in the Pacific Northwest study in their attitudes toward acceptable wilderness norms and behaviors. In most cases, Irish Wilderness respondents were more favorable to statements which reflected the goals of the 1964 Wilderness Act, although the amount of time which had elapsed between the two studies (15 years) should be taken into consideration.
Previous experience in the Irish Wilderness appeared to play a role in the individual's concurrence and compliance with the administrative policies of the area. This may also coincide with the fact that particular needs of the individual are being met within the wilderness area.
Successful management of wilderness areas may be enhanced by recognizing the needs of the individual and seeing that those needs mesh with the area's entire realm of wilderness attributes, of which recreational activities are a small part.

description: Este artigo resulta do estudo realizado no âmbito do projeto de investigaçãoo “Avaliação Externa de Escolas no Ensino não Superior”, financiado pela Fundação para a Ciência e Tecnologia. O objetivo desta comunicação consiste em contextualizar o ensino especializado da música face ao mundo atual e às políticas educacionais de accountability, escolas eficazes e a avaliação externa de escolas (Taubman: 2009). Segundo dados publicados pelo Ministério da Educação sobre o ensino especializado da música, é possível verificar que em Portugal há uma ausência de estudos científicos nesta área (Domingues: 2007). Em 2006 a implementação da Avaliação Externa de Escolas (AEE) veio promover junto dos Conservatórios a prestação de contas, a reorganização e a uniformização dos seus procedimentos, bem como a autoavaliação, conforme as políticas educativas nacionais. As tendências emergentes revelam que no ensino especializado da música, a AEE tem um efeito direto na reorganização interna das escolas, exigindo a todos os intervenientes os mesmos procedimentos com vista a uma uniformização e impondo a necessidade dos Conservatórios efetuarem a autoavaliação e autorreflexão.

description: In this work, we study the information content learned by a convolutional neural network (CNN) when trained to carry out the inverse mapping between a database of synthetic Ca II intensity spectra and the vertical stratification of the temperature of the atmospheres used to generate such spectra. In particular, we evaluate the ability of the neural network to extract information about the sensitivity of the spectral line to temperature as a function of height. By training the CNN on sufficiently narrow wavelength intervals across the Ca II spectral profiles, we find that the error in the temperature prediction shows an inverse relationship to the response function of the spectral line to temperature, this is, different regions of the spectrum yield a better temperature prediction at their expected regions of formation. This work shows that the function that the CNN learns during the training process contains a physically-meaningful mapping between wavelength and atmospheric height.

title: Temporal and spatial partitioning of the soil water resource between two Agropyron bunchgrasses and Artemisia tridentata
Creators: name: Thorgeirsson, Halldor
Publisher: name: Utah State University
Year: 1985

description: Dynamics of soil water use by two cool-season Agropyron bunchgrasses during the warm season depletion of soil water reserves were monitored for two years in experimental plots in the field. Agropyron desertorum, an introduced, competitive species from Eurasia, extracted more water from the deeper ( > 50 cm) soil layers than the native, less competitive Agropyron spicatum. Agropyron desertorum both extracts this water earlier and to lower soil water potentials than Agropyron spicatum. From the water extraction dynamics of the grasses in monocultures and in their two-way (50:50) mixtures with a shrub they commonly co-occur with, Artemisia tridentata, partitioning of the soil water resource between the grasses and the shrub was inferred. This indicated that Artemisia tridentata and Agropyron desertorum partitioned the soil water resource fairly evenly, while considerable quantities of water in the deeper soil layers under Agropyron spicatum seemed to be available to the shrub without direct competition. The implications of this difference in water resource partitioning for competition of the grasses with Artemisia tridentata are discussed. Predawn and midday xylem pressure potentials were not different between the two grasses in spite of different fluxes through the plants. Agropyron desertorum initiated new adventitious roots in fall and early spring while Agropyron spicatum did so only during spring. Observations from a root observation chamber indicated essentially parallel pattern of lateral root elongation during the depletion phase through top 200 cm of the profile. In both species the number of active tips, and the rate of elongation of active tips, decreased as the soil dried out. Root tips at all depths were inactive by the middle of September. Agropyron desertorum maintained root elongation at 50-110 cm for two weeks longer than A. spicatum.
title: A Descriptive Study of Range Livestock Operations in the Somali Central Rangelands

description: Information on livestock operations, particularly what kind of livestock operations are practiced in the Somali central rangelands, and how these operations differ for different herders in different vegetation types and farming systems, could serve as a major tool in making management decisions. This study provides a detailed description of range livestock operations in the Somali Central Rangelands. It also answers some important management questions.
Range livestock operations were inventoried through personal interviews with the owners and herders. Data are supplemented by previous nation-wide and regional survey statistics. Herd productivity data which include herd structures, age, age-related sales, slaughters, gifts, and Zakat (religious payment) was derived from the herd recording survey.
The results indicate the need for long term data to serve as a base for decisions concerning range and livestock development.

description: We construct an analogue of the normaliser decomposition for p-local finite groups (S,F,L) with respect to collections of F-centric subgroups and collections of elementary abelian subgroups of S. This enables us to describe the classifying space of a p-local finite group, before p-completion, as the homotopy colimit of a diagram of classifying spaces of finite groups whose shape is a poset and all maps are induced by group monomorphisms.

description: This article conceptualizes acting on media in terms of different interplays between focal actors, users, and user communities. It is argued that—in times of mediated visibility, the increasing entanglement of social and technological change, and accelerated feedback loops—arenas of negotiation emerge and therewith the complexities of relations between producers and users increases. Using insights from the fields of Wii hacking, Circuit Bending, and online poker tools, three variants of interplay are presented and discussed: integration, segregation, and permanent confrontation. Whilst a process-oriented perspective on reciprocal action is developed the paper contributes (a) to a balanced perspective on what is often a onesided discussion regarding the actions leading to media change, and (b) to the understanding of the relation between media change and reflexive modernity.
