Objective: To analyze the effect of low-level laser on bone remodeling during induced tooth movement in rats. Materials and Methods: A diode laser (808 nm, 100 mW, 54 J on an area of 0.0028 cm2) was used. The application was continuous, punctual, and with contact. Forty-two 70-day-old Wistar rats had the maxillary left first molar moved using a force level of 25 g. In two experimental subgroups the movement was performed over 7 days and in three subgroups the movement occurred over 14 days. In the 7-day movement subgroups, one subgroup received laser irradiation on day 1 only; the other subgroup received laser irradiation on days 1, 3, and 5. In the 14-day movement subgroups, one subgroup received laser irradiation on day 1 only; the second on days 1, 3, and 5; and the third on days 1, 3, 5, 7, 9, 11, and 13. The control group was also divided into two subgroups, and movement occurred over two different periods of treatment (7 days and 14 days) without laser application; these were used as controls for the respective experimental subgroups. Inter-subgroup comparison was performed with Kruskal-Wallis, followed by Mann-Whitney and analysis of variance, followed by Tukey tests within the 7- and 14-day subgroups. Results: The subgroup with three laser applications showed significantly greater osteoclastic activity and bone resorption than the other subgroups in the 7-day movement subgroups. Conclusions: Low-level laser application significantly increased the osteoclastic but not the osteoblastic activity during the initial phases of tooth movement. In addition...

Esta tese tem como objeto de estudo a ação coletiva do movimento social surdo no processo histórico que culminou na Lei Federal nº 10.436, de 24 de abril de 2002, que reconheceu a língua brasileira de sinais (Libras) como meio legal de comunicação e expressão no Brasil. A pesquisa foi desenvolvida conforme pressupostos e práticas da metodologia qualitativa, sendo as principais técnicas de coleta de dados utilizadas a entrevista, principalmente com ativistas surdos participantes dos acontecimentos estudados, e a pesquisa documental nos arquivos de organizações, instituições e órgãos públicos envolvidos no processo investigado. Por seu turno, o marco teórico da pesquisa foi embasado na obra do sociólogo Alberto Melucci. Adotando a perspectiva melucciana, a tese descreve o movimento social surdo brasileiro como sendo um sistema de relações sociais composto principalmente por pessoas surdas usuárias da Libras, grupos e organizações de surdos. Esclarece, em primeiro lugar, que esse movimento emergiu nos anos 1980 relacionado ao movimento social das pessoas com deficiência e mostra como o seu desenvolvimento foi favorecido pelas transformações na estrutura de oportunidades políticas que estavam sendo causadas pela redemocratização após o regime ditatorial militar (1964-1985). Em segundo lugar...

Os processos de dinâmica superficial, como os movimentos de massa são eventos naturais e fazem parte da dinâmica do planeta. Quando ocorrem em áreas ocupadas, podem acarretar consequências econômicas e sociais de significativa dimensão. Esta problemática é verificada no município de Porto Alegre, onde constantemente são registrados movimentos de massa. O objetivo geral desta pesquisa consiste em identificar e mapear as áreas com perigo de movimentos de massa em Porto Alegre. Para tanto, foi realizado o levantamento do histórico de ocorrências de movimentos de massa no período entre 1995 e 2010, o estudo dos materiais superficiais, suscetibilidade e ocupação do solo. Os procedimentos metodológicos foram organizados em 4 etapas: levantamento de dados referentes aos registros de movimentos de massa e de bases cartográficas; organização dos registros e das bases cartográficas; análise e correlação das informações sobre os registros de movimentos de massa e mapas de relevo, geologia e pedologia para a definição do mapa de suscetibilidade a movimentos de massa; síntese das informações para definição do mapa das áreas com perigo de movimentos de massa a partir do cruzamento dos mapas de suscetibilidade e uso do solo. Os resultados indicam que os bairros Cascata...

O objetivo da presente pesquisa foi avaliar a influência do estresse sistêmico e de um antiinflamatório no movimento dentário ortodôntico. No experimento 1, os efeitos do estresse sistêmico sobre a movimentação ortodôntica foram avaliados em ratos estressados (por contenção) em modelos de estresse de curta (3 dias) ou longa duração (40 dias). O grupo controle não foi submetido à contenção. O primeiro molar superior esquerdo dos ratos foi movimentado mesialmente nos últimos 14 dias do experimento. Logo depois, os animais foram mortos por decapitação para coleta de sangue e mensuração da corticosterona plasmática; o movimento dentário foi quantificado e os tecidos ao redor da raiz mesial do primeiro molar foram processados para análise histoquímica por coloração para fosfatase ácida tartarato-resistente (TRAP). O estresse crônico produziu maior taxa de movimentação dentária e aumentou o número de osteoclastos em relação ao grupo controle e ao grupo submetido ao estresse de curta duração, que não diferiram entre si. Não houve diferença entres os grupos em relação ao número de odontoclastos e ao grau de reabsorção radicular. No experimento 2, os efeitos da administração de celecoxibe, em regimes de curta (3 dias) e longa duração (14 dias)...

Movement of individual organisms is fundamental to life, quilting our planet in a rich tapestry of phenomena with diverse implications for ecosystems and humans. Movement research is both plentiful and insightful, and recent methodological advances facilitate obtaining a detailed view of individual movement. Yet, we lack a general unifying paradigm, derived from first principles, which can place movement studies within a common context and advance the development of a mature scientific discipline. This introductory article to the Movement Ecology Special Feature proposes a paradigm that integrates conceptual, theoretical, methodological, and empirical frameworks for studying movement of all organisms, from microbes to trees to elephants. We introduce a conceptual framework depicting the interplay among four basic mechanistic components of organismal movement: the internal state (why move?), motion (how to move?), and navigation (when and where to move?) capacities of the individual and the external factors affecting movement. We demonstrate how the proposed framework aids the study of various taxa and movement types; promotes the formulation of hypotheses about movement; and complements existing biomechanical, cognitive, random, and optimality paradigms of movement. The proposed framework integrates eclectic research on movement into a structured paradigm and aims at providing a basis for hypothesis generation and a vehicle facilitating the understanding of the causes...

Movement is important to all organisms, and accordingly it is addressed in a huge number of papers in the literature. Of nearly 26,000 papers referring to movement, an estimated 34% focused on movement by measuring it or testing hypotheses about it. This enormous amount of information is difficult to review and highlights the need to assess the collective completeness of movement studies and identify gaps. We surveyed 1,000 randomly selected papers from 496 journals and compared the facets of movement studied with a suggested framework for movement ecology, consisting of internal state (motivation, physiology), motion and navigation capacities, and external factors (both the physical environment and living organisms), and links among these components. Most studies simply measured and described the movement of organisms without reference to ecological or internal factors, and the most frequently studied part of the framework was the link between external factors and motion capacity. Few studies looked at the effects on movement of navigation capacity, or internal state, and those were mainly from vertebrates. For invertebrates and plants most studies were at the population level, whereas more vertebrate studies were conducted at the individual level. Consideration of only population-level averages promulgates neglect of between-individual variation in movement...

The facial phenotype of psychogenic movement disorders has not been fully characterized. Seven tertiary-referral movement disorders centers using a standardized data collection on a computerized database performed a retrospective chart review of psychogenic movement disorders involving the face. Patients with organic forms of facial dystonia or any medical or neurological disorder known to affect facial muscles were excluded. Sixty-one patients fulfilled the inclusion criteria for psychogenic facial movement disorders (91.8% females; age: 37.0 ± 11.3 years). Phasic or tonic muscular spasms resembling dystonia were documented in all patients most commonly involving the lips (60.7%), followed by eyelids (50.8%), perinasal region (16.4%), and forehead (9.8%). The most common pattern consisted of tonic, sustained, lateral, and/or downward protrusion of one side of the lower lip with ipsilateral jaw deviation (84.3%). Ipsi- or contralateral blepharospasm and excessive platysma contraction occurred in isolation or combined with fixed lip dystonia (60.7%). Spasms were reported as painful in 24.6% of cases. Symptom onset was abrupt in most cases (80.3%), with at least 1 precipitating psychological stress or trauma identified in 57.4%. Associated body regions involved included upper limbs (29.5%)...

Freedom of movement is a matter of individual freedom rather than only a tool for addressing global distributive injustice. Freedom of movement has normative value whether or not it concerns interstate borders. Migration, in the sense of interstate relocation, is a subcategory of movement, which can involve travel, temporary relocation or permanent relocation--a brief walk, or a move halfway around the world. My argument about freedom of movement has two essential elements: first, that freedom of movement has noninstrumental value, not only instrumental value, and that it deserves more weight and attention than liberals usually give it; and second, I justify this and its implications by emphasizing the cross-scalar connections between local and global movement and showing that the difference between internal and interstate movement is not as significant as is usually assumed to be. Freedom of movement is proposed as a unit of concern and a matter of degree, with principles and restrictions functioning in parallel at both levels. The cohesive account of liberal freedom of movement offers the chance to think about people moving and staying as one overarching category. This challenges the characterization of migration as anomalous and captures the chance to treat like cases alike. Chapter Two makes an argument for freedom of movement as a noninstrumental liberal value to which the normative weight of the instrumental value of freedom of movement is added. Chapter Three explores small-scale movement in the countryside and the city and proposes a stronger valuation of freedom of movement particularly vis-à-vis private property rights. Chapter Four considers theoretical and legal arguments involving intrafederal movement in the United States and Germany and compares intrafederal exit to exit from the state. Chapter Five considers several free movement regimes in Europe to draw out the similarities between interstate...

peer-reviewed; Movement variability, while being a topic discussed extensively throughout the movement sciences, is still not understood. The effect of movement variability on outcome has not been ascertained. In particular, there has been a dearth of research investigating movement variability in the golf swing. The objective of this thesis was to investigate the effect of movement variability on outcome and outcome variability. Using experimental methods, the initial aim of this thesis was to quantify movement variability of sixteen participants and investigate the relationship between the quantified movement variability and outcome variability in the golf swing. The results indicated no statistically significant relationship between movement variability and outcome variability either in the backswing or downswing phase of the swing. Following this, modelling methods were used in the investigation of movement variability on outcome in the golf swing. Firstly, a computer model of a participant’s golf swing was created and validated. Then a method to apply movement variability at single anatomical points to the computer model was developed. Subsequently, different levels of movement variability were applied to single anatomical points in the computer model. The results revealed there was no practical effect on outcome. In order to investigate movement variability of measures more complex than single anatomical points...

Cephalopod movement occurs during all phases of the life history, with the abundance and location of cephalopod populations strongly influenced by the prevalence and scale of their movements. Environmental parameters, such as sea temperature and oceanographic processes, have a large influence on movement at the various life cycle stages, particularly those of oceanic squid. Tag recapture studies are the most common way of directly examining cephalopod movement, particularly in species which are heavily fished. Electronic tags, however, are being more commonly used to track cephalopods, providing detailed small- and large-scale movement information. Chemical tagging of paralarvae through maternal transfer may prove to be a viable technique for tracking this little understood cephalopod life stage, as large numbers of individuals could be tagged at once. Numerous indirect methods can also be used to examine cephalopod movement, such as chemical analyses of the elemental and/or isotopic signatures of cephalopod hard parts, with growing interest in utilising these techniques for elucidating migration pathways, as is commonly done for fish. Geographic differences in parasite fauna have also been used to indirectly provide movement information...

This thesis examines the emotion-based strategies employed by activists for the purpose of persuading individuals to participate directly in social movements. In particular, the emphasis is placed on getting people involved in ‘altruistic’ mobilisation; a descriptive utilised in order to distinguish these movements from previous research done in which a tangible material gain is presented as an inducement for participation. The thesis investigates the animal rights movement as it pertains to the issue of animal vivisection, and endeavours to identify the linguistic strategies employed by these activists with the goal of understanding how to facilitate ‘altruistic’ movements more generally. A textual analysis, which was consistent with Halliday’s (2004) systemic functional linguistics, was conducted on mobilisation pamphlets written by groups seeking support for either animal vivisection or animal rights. To this end, the analysis considered both the original movement (i.e. the anti-vivisection movement) and the counter-movement (i.e. the pro-research movement). The analysis considers the linguistic and visual strategies used by movement organisers in placing a moral onus on the reader to support the movement. From this analysis it is argued that the success of the animal rights movement stems from its ability to present graphic visual imagery that supplies evidential support for the claims being made in text. In addition...

This thesis examines futōkō (school non-attendance) in Japan from the perspective that futōkō is a social movement. It analyses citizens’ activism in support of futōkō students over the twenty year period from 1984. Drawing upon social movement approaches the thesis examines how futōkō citizens successfully grasped political opportunities, established a network of organizations, launched a new interpretive frame for futōkō, and challenged the dominant representation of futōkō in society –that 'futōkō is an illness’. To explore in detail the ideological aspect of the futōkō movement’s framing, a content analysis of 140 editorials in the movement newspaper – the Futōkō Shimbun (School Non-attendance Newspaper) was conducted. Commencing with a critique of schooling practices that create futōkō, over the survey period Futōkō Shimbun expands its analysis to develop a critical appraisal of Japanese society that has broad implications for many different aspects of the everyday life of its citizens. Adopting the typology of movement outcomes, this thesis assesses the outcomes of futōkō movement framing through two sets of factors: first, changes in government policies and attitudes and second, cultural and ideational changes as experienced by the movement organizations...

The Australian Republican Movement (ARM) has in recent years experienced the lowest public interest in the issue of the republic since the organisation's inception in 1991. The ARM's National Committee has identified closer identification of the movement with Australian national identity, symbols and themes as one of its 2007 objectives. The path from the formation of the ARM in 1991 to referendum in 1999 demonstrated how national identity is an issue at the heart of the republican debate. The varying constructions of national identity as the years progressed, as the focus on Asia and regional issues under Keating changed to Howard's emphasis on protecting traditional Australian identity, have had impacted progress toward a republic. In order to encourage wider public support, the ARM should align itself with the current dominant ideas of national identity. Instead relying on the unpopular conceptions of national identity that supported the growth of the movement in the early 1990s, the movement must align itself with a more traditional national identity. The defeat in the 1999 republic referendum demonstrated the need for the ARM to assess how the movement can connect itself with the most dominant and popular version of national identity. The republic was perceived as an issue irrelevant to many Australians arid the 'No' Committee campaign emphasised this...

The green movement has evolved over the last twenty years from various social, peace and ecology activist organizations into direct political participation in parliamentary institutions through the Green Party. Although there is no definable theory of green politics, the culmination of interacting social movements as well as feminist, decentralist and in many cases, left wing political ideology, has produced a specific kind of political direction for the Greens internationally. As a result of the increased a ttention and awareness given to ecological issues , combined with the heightened evidence of large scale environmental deterioration, public attitudes and government decisions on development and natural resource management have been significantly altered. The Green Party of Canada is still r elatively young in comparison to its European counterparts, although ecologica l awareness and interest in t he green movement in Canada is strong, as reflected not only in support on a political level for the Canadian Greens I but for environmental issues and a ctivism in general. For this reason it s important to determine whether or not the Green Party is a significant aspect of the Canadian green movement, and if in fact its representation is necessary as an active participant in the Canadian political system . The Green Party of Canada...

In the post-9/11 world, Bangladesh has been identified as a new hub of the Al-Qaeda network in South Asia. Most of the contemporary national and international media reports, security documents, and even academic studies point to the fact that an Islamist movement is on the dramatic rise in Bangladesh in recent years. These reports and studies portray the Islamist movement as closely linked with terrorism and devoid of any historical roots and relations with other types of movement. Contrary to this view, this study argues that the Islamist movement is not an unprecedented phenomenon but historically linked with a broader militia movement which subsequently leads to the emergence of Bangladesh as a nation state in 1971. Since its inception, the nation state is dealing not only with the Islamist movement but also with two other types of militia movement almost simultaneously – the leftwing and the ethnic. Having identified these three types, this study defines the militia movement in terms of five analytical categories – ideology, motivation, mobilization, organization, and ritual – following Freilich and others. It analyzes the Bangladesh militia movement in terms of these five dimensions, providing historical-empirical data from both primary and secondary sources to show how the contemporary militias are carrying forward the legacy of their historical forerunners. This study concludes with policy recommendations on how informed decisions can be made to effectively deal with the militia issue.; Thesis (Master...

CAPÍTULO 2: O tamanduá bandeira é a maior espécie de tamanduá do mundo. É um animal de hábitos terrestres, entretanto apresenta alguma habilidade para escalar árvores e cupinzeiros altos. As estruturas esqueléticas duras são de importância vital, pois unem e protegem os órgãos moles e permitem sustentar o corpo, dão forma e se envolvem no movimento. O esqueleto apendicular é parte importante do aparelho locomotor, cujas informações anatômicas em espécies selvagens são escassas, tornando difícil a interpretação de dados relativos a esses ossos. O presente artigo teve por objetivo descrever o esqueleto da região glútea, coxa e perna do tamanduá bandeira. Foram utilizados dois espécimes de Myrmecophaga tridactyla Linnaeus (1758) fixados em solução aquosa de formaldeído a 3,7%. Inicialmente os membros foram desarticulados e foi realizada a retirada da pele, vísceras e musculatura associada aos ossos da região glútea, coxa e perna dos espécimes. Em seguida os mesmos foram macerados em água fervente e posteriormente colocados em solução de peróxido de hidrogênio. Depois de limpos e secos, os ossos foram identificados e descritos. O esqueleto da região glútea do tamanduá bandeira é constituído pelo osso do quadril...

Covert movement is movement that is not phonologically visible in the syntactic derivation. While covert A'-movement is widely proposed, covert A-movement is quite uncommon and difficult to identify. This chapter discusses diagnostics for covert A-movement and ways in which it can be distinguished from non-movement. We propose that covert A-movement is found in subject-to-subject raising in the Northwest Caucasian language Adyghe (Potsdam and Polinsky 2012). We compare the Adyghe construction with unaccusatives in Russian, which we show do not involve covert A-movement (contra Babyonyshev et al. 2001). We demonstrate that a range of mostly theory independent phenomena can be used to determine whether covert A-movement occurs in a given construction, using Adyghe and Russian as contrasting test cases.; Linguistics

Young, idealistic, and ready to test the waters of American democracy, the Northern Student Movement represented a segment of the New Left that sought a more active involvement in the nation’s affairs while attempting to reform the Old Left, or the old “liberal tradition” that focused on ideology. Inspired by the anti-war movement and the black freedom struggle, northern college students found ways to get involved in the civil rights movement. During the 1960s sit-ins, many found their way “down South.” Peter Countryman, a Yale student, was one of those profoundly impacted by black leaders in the South. Deciding to become active, Countryman and a group of students spearheaded the Northern Student Movement. From their founding conference in 1962, the NSM would lead a remarkable effort in the North to remedy deeply rooted racial injustices, while reforming their approach to local political struggle in hopes of building an independent black North that was free.

Black Power Does Not Come Out of the Sky tells the story of the interracial community organizing tradition and its evolution during the 1960s through the lens of the Northern Student Movement. It tells the story of how young college students across northern cities worked with local...

Infusing models for animal movement with more behavioral realism has been a goal of movement ecologists for several years. As ecologists have begun to collect more and more data on animal distribution and abundance, a clear need has arisen for more sophisticated analysis. Such analysis could include more realistic movement behavior, more information on the organism-environment interaction, and more ways to separate observation error from process error. Because landscape ecologists and behavioral ecologists typically study these same themes at very different scales, it has been proposed that their union could be productive for all (Lima and Zollner, 1996).

By understanding how animals interact with their land- and seascapes, we can better understand how species partition up resources are large spatial scales. Accordingly I begin this dissertation with a large spatial scale analysis of distribution data for marine mammals from Nova Scotia through the Gulf of Mexico. I analyzed these data in three separate regions, and in the two data-rich regions, find compelling separation between the different communities. In the northernmost region, this separation is broadly along diet based partitions. This research provides a baseline for future study of marine mammal systems...

There is considerable variation among social movements in the degree to which they are organized and Integrated. Usually, however, integration and coordination are problematsic for social movements as they tend to be marked by considerable dissensus. As Rillian has noted: "Many movements are comprised of diverse segments, each with its own structure, loosely united only by their allegiance to the central, explicit values and by the tendancy of outsiders to view them as parts of a single who1e." In many cases, there is no overall formal organlzation or structure which wields such diverse elements together. In fact, the interaction between the various components of a social movement is often characterized by conflict. There are points in the life history of some social movements, however, when the disintegrative tendencies are cancelled out, or are temporarily neutralized. Such periods are characterized by a growing consensus among the various components of a movement regarding such matters as goals and tactics, and a heightened sense of in-group consciousness. Under these circumstances, greater coordination and integration may emerge among the diverse segments of a movement, thus enabling it to have a profound affect upon its environment. In this paper...
