Baquedano-Lopez, Patricia. « Narrating Community in Doctrina Classes ». Narrative Inquiry 10, no 2 (31 décembre 2000) : 429–52. http://dx.doi.org/10.1075/ni.10.2.07baq.
Texte intégralRésumé :
While narrative focuses on particular protagonists and events, narrative also situates tellers and their audiences within a web of historical and cultural expectations, ideologies, and meanings, more broadly. As such, narrative creates shared understandings and community among those participating in narrative activity. Moreover, the narrative process extends beyond the boundaries of the here and now to embrace people and places in a cultural past. This article examines the religious narrative accounts of the apparition of Nuestra Señora de Guadalupe told in children’s religious education classes called doctrina at a Catholic parish in Los Angeles. The children that attend these classes are of Mexican descent and their lessons are taught in Spanish. The article analyzes the linguistic and interactional means through which narrative renditions of the story of Nuestra Señora de Guadalupe construct Mexican identity. The narrative renditions tell the story of the apparition of the Virgin Mary in Tepeyac, near Mexico City, in the year 1531, thirteen years after the fall of the Aztec empire to the Spanish conquest. These diasporic narrative accounts transcend time and space, as they continue to be told by Mexican Catholics at places beyond the geopolitical borders of Mexico. Moreover, these narrative tellings are instrumental for positioning teachers and students in a postcolonial moment that revisits the hierarchies of Mexico’s colonial regime vis-à-vis their current experiences as immigrants in Los Angeles.

Texte intégralRésumé :
AbstractIt is traditionally accepted among scholars that the "original" episode of the Akedah is narrated in Gen. xxii 1-13, 19. Verses 14-18, the "second angelic speech", offering Abraham a blessing for his obedience, are usually considered, on stylistic, structural and critical grounds, a secondary interpolation. Recent studies, however, have argued that Abraham's extraordinary obedience actually necessitates the extra blessings which he receives in the second angelic speech. It, therefore, could not have been simply inserted into the original account. This has suggested to many scholars that the author responsible for vv. 15-18 has left his mark also on vv. 1-13, 19. In re-examining the style, composition and content of this story, I will suggest that the mark may be found in the first angelic speech, stopping Abraham at the crucial moment (vv. 11-12). Without the angelic intervention an episode would emerge in which Abraham disobeyed the divine command, sacrificing the ram "instead of his son", on his own responsibility.

Texte intégralRésumé :
The present article proposes that Enoch’s status in Watchers and Parables is virtually angelic. It then goes on to compare the knowledge revealed to angelified Enoch with the teachings of the fallen angels in those two Enochic booklets. It becomes clear that the subjects taught by the Watchers are negative aspects of subjects apprehended by Enoch is his angelified state. Thus the status of the revealer determines what can be revealed.

Texte intégralRésumé :
The evolutionary creation model of origins best matches the scientific evidence for evolution with common descent. However, the violence and harm associated with the evolutionary history of life may be viewed as incompatible with religious traditions such as Anabaptist that understand God to be nonviolent as revealed in the life and teaching of Jesus. This article argues that malevolent wills such as fallen angels opposed God's will in the evolutionary process and that explanations for natural evils that do not recognize the corrupting activities of fallen spirit-beings make God culpable for evil and non-Christlike in moral character. In this light, the rejection of the angelic-fall thesis by many writers is surprising. Consequently, a number of common objections to the thesis are examined. The angelic-fall approach to natural evil has biblical support, a long history in the church, support of some current-day theologians, the ability to resist objections, and many useful outcomes.

Fox, Michael. « Ælfric on the creation and fall of the angels ». Anglo-Saxon England 31 (décembre 2002) : 175–200. http://dx.doi.org/10.1017/s0263675102000078.
Texte intégralRésumé :
Ælfric, in the Preface to Genesis, comments about what we do not find in the first book of the Old Testament: ‘Seo boc ys gehaten Genesis, Þæt ys “Gecyndboc”, for Þam Þe heo ys firmest boca and spricÞ be ælcum gecinde (ac heo ne spricð na be Þæra engla gesceapenisse).’ Although he proceeds to explain what is contained in the opening verse, noting that creation ‘on annginne’ refers at once to the literal act of creation and, ‘æfter gastlicum andgite’, to Christ through whom all creation was formed, he makes no further comment here upon the angels. In other works, however, where the topic could be more appropriately introduced, Ælfric enthusiastically engages with the problem of angelic history. The sermon De initio creaturae, the Interrogationes Sigewulfi, the Exameron, the Letter to Sigeweard and the Letter to Wulfgeat all contain accounts of the angelic creation and fall. Because Ælfric is a writer actively concerned with orthodoxy and sound doctrine, we would do well to ask why he has such an interest in the angels–about whom such an authority as Bede would say almost nothing–and to investigate precisely how, and from what sources, he presents their extra-scriptural history.

Purgin, Sergey P. « Angelic Dynamism : Humanity in Paul Klee’s Drawing Series of 1939–1940 ». Vestnik of Saint Petersburg University. Arts 11, no 3 (2021) : 512–31. http://dx.doi.org/10.21638/spbu15.2021.308.
Texte intégralRésumé :
Since Walter Benjamin in “The Theses on the Philosophy of History” showcased Paul Klee’s angels, they remain mysterious figures that represent time, history or soul. The article focuses on the series of drawings that were created in the artist’s later period (1939−1940). The series can be regarded as the artist’s final will and testament as it expresses Klee’s condensed philosophy and mature views on man’s place in the universe. It also reflects the master’s cherished artistic methods and techniques, consistently honed in on during the course of his life. The author studies the relations within the series and the series relation to other artworks by Klee. It is demonstrated that it is humankind that is the main theme of the series. By contrasting human and angelic forms in his drawings Klee reinvigorates the European tradition of defining humanity through its relation to angelic orders and through its position on the hierarchy of creation. However, Klee strives to re-imagine the universe as a whole, for him it is not the ladder of perfections, which rises to angels and God. Therefore, the relations between human and angelic creatures are intimately familial rather than hierarchical. The author highlights that the artistic style and techniques emphasize visual dynamic and form creation (“formation”). In depicting angels, the artist brings forth his concern with temporal dimension of human nature and its significance in human life. Thus, in this dynamic interrelation, human beings become “angelic grotesque” with their own ontic temporality. This temporality specific to human creatures is defined as the “moment that transcends itself ” — since the latter is essentially “ecstatic” and “self-propelling”.

Wong, Donald Ho-Lun. « The Emergence and Implication of the Role of Angels in Augustine’s Understanding of Creation : The Extension and Mirroring of Christ ». Religions 14, no 3 (28 février 2023) : 322. http://dx.doi.org/10.3390/rel14030322.
Texte intégralRésumé :
Angels take on a unique role in Augustine’s understanding of creation. Traditionally, researchers have focused on De Genesi ad litteram libri duodecim, Confessiones, and De Civitate Dei contra paganos to generate a descriptive account of the angelic role in creation. As such, not much attention has been paid to the emergence of his understanding of angels in his earlier texts. The largely descriptive accounts have also left the theological implication, specifically the linkage between Augustine’s angelology and Christology, unaddressed. This paper offers a two-fold contribution. First, this paper argues that the often-overlooked text De Genesi ad litteram imperfectus liber represents the pivotal moment in the development of Augustine’s germinating thoughts on angels and creation. Augustine’s mature notions of angels as created light and created wisdom, as well as angelic noetic movement, find their roots in De Genesi ad litteram imperfectus liber. Second, this paper argues that, from De Genesi ad litteram imperfectus liber to his more mature works, angels extend Christ’s work in creation. Augustine solves the problem of fashioning the corporeal from the spiritual by locating the production of intellectual prototypes within angels. Together with the designation of angels as “knowledge”, “light”, and “wisdom”, angels mirror Christ’s activity as creator.

Texte intégralRésumé :
The first page of the invisible creation changed at the dawn of its beginnings. The crisis of authenticity has disfigured Lucifer (the opposite of existential transfiguration), the genius of shadowing light behind the wall of darkness. The fall brought, to the angelic order „foresitter”, the forever loss of its genuine state as virtuous angel. In other words, the guardian cherubim of the celestial armies wished to install an eschatology of disorder and evil in God's creation. In fact, the „morning star of dawn” had in mind to draw „a new heaven and a new earth” where evil, dismantling and chaos were supposed to be the governing laws. His wrong understanding of beings' personal freedom will bring the scaffold of his self-petrification.

Texte intégralRésumé :
Firstly, the characteristics of person-parachute sys-tem (PPS) in free-fall phase are analyzed. Then, the particle motion equations of PPS are built up. The motion law of PPS in free-fall phase is found by computing. Fall synthesis velocity decreases firstly, then gradually increases, so there is a minimum value of synthesis velocity when is favorable parachute opening moment. Results and actual test show good agreement, which provides an evidence for determining parachute opening moment.

Texte intégralRésumé :
On April 9th, the entire world watched as American troops threw a noose round the neck of the dictator and, surrounded by jubilant throngs of Iraqis, pulled him off his pedestal. The apparently unshakeable monument tottered, and then finally fell. But before it crashed satisfyingly to the ground, there was a momentary pause before the force of gravity could overcome the statue's grotesquely unnatural, horizontal posture. Bobbing gently up and down, the massive figure clung, for one last moment, to its horror.

Texte intégralRésumé :
This article conducted an analysis on the multiple images of the Devil, based on three illuminations of the 15th century. It is possible to observe the following elements: 1-the evil one as a head, with a huge open mouth, known as the Hellmouth; 2-as a human being, but with animalistic characteristics, carrying claws, the tail, among other things, still with devouring aspect; 3-represented in beautiful shape, as the rebel angel, Lucifer, expelled from heaven by God. Three images were analyzed; one from the narrative Vision of Tondal, which it is represented as the Beast Acheron, in the form of Hellmouth, and two images of the book Les Très Riches Heures of the Duc de Berry (The Very Rich Hours of the Duke of Berry), when figured with animalistic features in the image entitled "Inferno" (fl.108r) and with his angelic features in "The fall of the Rebel Angels" (fl. 64v). In the last two illuminations the Devil presents ruler of Hell elements. Moreover, it is clear that this has ambiguous features in Christian imagination.

Visser, Matt. « Quantum mechanix plus Newtonian gravity violates the universality of free fall ». International Journal of Modern Physics D 26, no 12 (octobre 2017) : 1743027. http://dx.doi.org/10.1142/s0218271817430271.
Texte intégralRésumé :
Classical point particles in Newtonian gravity obey, as they do in general relativity, the universality of free fall. However, classical structured particles, (for instance with a mass quadrupole moment), need not obey the universality of free fall. Quantum mechanically, an elementary “point” particle (in the particle physics sense) can be described by a localized wave packet, for which we can define a probability quadrupole moment. This probability quadrupole can, under plausible hypotheses, affect the universality of free fall. (So point-like elementary particles, in the particle physics sense, can and indeed must nevertheless have structure in the general relativistic sense once wave packet effects are included.) This raises an important issue of principle, as possible quantum violations of the universality of free fall would fundamentally impact on our ideas of what “quantum gravity” might look like. I will present an estimate of the size of the effect, and discuss where if at all it might be measured.

The speeches delivered by Al Gore and George W. Bush at the conclusion of the contested 2000 U.S. presidential campaign are of especial interest because they represent a type of political speech that is virtually unique and, because the speakers and their staffs had no previous models to fall back upon, as spontaneous as political utterance currently gets. This paper analyzes those speeches, focusing on the relationships between their forms and what their speakers feel they have to do, and finds interesting similarities as well as differences, in style and content, between them.

Arquivos de Neuro-Psiquiatria 65, no 3a (septembre 2007) : 623–27. http://dx.doi.org/10.1590/s0004-282x2007000400015.
Texte intégralRésumé :
The main goal of the present study was to analyze theta asymmetry through quantitative electroencephalography (qEEG) when individuals were exposed to a sequential motor task, i.e. catching a ball. The sample was composed of 23 healthy subjects, male and female, between 25 and 40 years of age. A two-way factor Anova was applied to compare pre and post moments related to the balls' drop and scalp regions (i.e., frontal and parieto-occipital cortices). The first analysis of the frontal region compared electrodes in the left, right and left/right hemispheres combined, with the frontal midline electrode (FZ) included in the analysis. The results showed moment and region main effects. The second analysis compared left versus right hemisphere without the FZ site. The findings demonstrated an interaction effect between moment and region. The first parieto-occipital analysis, comparing left, right and central regions, with PZ included in all regions, showed main effects of moment and region. The second analysis, comparing left, right (without Pz) and central regions strictly demonstrated a region main effect. Thus, we observed an asymmetric pattern in the frontal cortex (i.e., planning and response selection) when the subjects were waiting for the balls' drop. Moreover, the left hemisphere seems to engage differently from the other regions when the central nervous system needs to prepare for a motor action. On the other hand, the parieto-occipital cortex, which is related to attentive processes, demonstrated a more asymmetric activity towards the right region which implies a participation of this area in cognitive strategies in this particular task. Taken together, we concluded that the adopted experimental approach can be useful to explore several others directions combining sensorimotor integration tasks with different pathologies, such as depression, Alzheimer's and Parkinson's diseases.

Prosthetics and Orthotics International 43, no 2 (7 septembre 2018) : 148–57. http://dx.doi.org/10.1177/0309364618796849.
Texte intégralRésumé :
Background: Knee osteoarthritis is a major contributor to the global burden of disease. There is a need of reducing knee joint load and to improve balance and physical function among knee osteoarthritis patients. Objectives: To test the hypothesis that toe-out gait will reduce second peak knee adduction moment further and increase fall risk when combined with knee brace and laterally wedged insole in knee osteoarthritis patients. Study design: Single visit study with repeated measures. Methods: First and second peak knee adduction moments, fall risk and comfort level. First and second peak knee adduction moments were determined from three-dimensional gait analysis, completed under six randomized conditions: (1) natural, (2) knee brace, (3) knee brace + toe-out gait, (4) laterally wedged insole, (5) laterally wedged insole + toe-out gait, and (6) knee brace + laterally wedged insole + toe-out gait. Fall risk was assessed by Biodex Balance System using three randomized stability settings: (1) static, (2) moderate dynamic setting (FR12), and (3) high dynamic setting (FR8). Results: The reduction in first peak knee adduction moment and second peak knee adduction moment was greatest (7.16% and 25.55%, respectively) when toe-out gait combine with knee brace and laterally wedged insole. Significant increase in fall risk was observed with knee brace + laterally wedged insole + toe-out gait (42.85%) at FR12. Similar significant balance reductions were found at FR8 condition for knee brace + toe-out gait (35.71%), laterally wedged insole + toe-out gait (28.57%), and knee brace + laterally wedged insole + toe-out gait (50%) as compared to natural. However, knee brace decreased fall risk at FR12 by 28.57%. Conclusion: There is a synergistic effect of toe-out when combined with knee brace and laterally wedged insole concurrently in second peak knee adduction moment reduction but with a greater degree of fall risk. Simultaneous use of conservative treatments also decreases comfort level. Clinical relevance Patients with mild and moderate knee osteoarthritis are usually prescribed conservative treatment techniques. This study will provide an insight whether or not a combination of these techniques have a synergistic effect in reducing knee joint load.

Texte intégralRésumé :
Motivations for physics beyond the Standard Model are reviewed, with particular emphasis on supersymmetry at the TeV scale. Constraints on the minimal supersymmetric extension of the Standard Model with universal soft supersymmetry-breaking terms (CMSSM) are discussed. These are also combined with the supersymmetric interpretation of the anomalous magnetic moment of the muon. The prospects for observing supersymmetry at accelerators are reviewed using benchmark scenarios to focus the discussion. Prospects for other experiments including the detection of cold dark matter, μ → e γ and related processes, as well as proton decay are also discussed.

A precise measurement of the anomalous g value, a = (g - 2)/2, for the positive muon has been made at the Brookhaven Alternating Gradient Synchrotron. The result aμ+ = 11 659 202(14)(6) × 10-10 (1.3 ppm) is in good agreement with previous measurements and has an error one third that of the combined previous data. The measurement tests standard theory and has the potential to discover new physics. The analysis of data collected in 2000 and 2001 is well underway and, when combined with data from a requested and final run in the fall of 2002 and winter of 2003, are expected to reduce the experimental uncertainty on aμ to 0.4 ppm.

Texte intégralRésumé :
Abstract Numerical weather prediction (NWP) simulations using the Japan Meteorological Agency Nonhydrostatic Model (JMA-NHM) are conducted for three precipitation events observed by shipborne or spaceborne W-band cloud radars. Spectral bin and single-moment bulk cloud microphysics schemes are employed separately for an intercomparative study. A radar product simulator that is compatible with both microphysics schemes is developed to enable a direct comparison between simulation and observation with respect to the equivalent radar reflectivity factor Ze, Doppler velocity (DV), and path-integrated attenuation (PIA). In general, the bin model simulation shows better agreement with the observed data than the bulk model simulation. The correction of the terminal fall velocities of snowflakes using those of hail further improves the result of the bin model simulation. The results indicate that there are substantial uncertainties in the mass–size and size–terminal fall velocity relations of snowflakes or in the calculation of terminal fall velocity of snow aloft. For the bulk microphysics, the overestimation of Ze is observed as a result of a significant predominance of snow over cloud ice due to substantial deposition growth directly to snow. The DV comparison shows that a correction for the fall velocity of hydrometeors considering a change of particle size should be introduced even in single-moment bulk cloud microphysics.

Texte intégralRésumé :
Taking into account the dynamics of a human body in its daily movement, one can study the forces that are generated in its variations with respect to a normal walk. These forces can be reduced, generating an opposite force through some device if one takes into account that their magnitude is not very large in some cases. This paper outlines results obtained from the sensorization of a human body in uniform movement, and changes in angular velocity and moment of a force produced by different inflections in normal movement. The aim was to calculate the moment of a force thanks to the measured angular velocity, and then study the opposition to this movement by using the produced reaction by the conservation of angular moment (gyroscopic effect). The study was carried out through the positioning of different sensors that were placed to analyze points of interest of the movement. In this study, we were able to appreciate changes in the variables to study up to two orders of magnitude at the generated moment, when the movement went from being uniform, which is equivalent to a walk, to the situation of an inflection, for example, a fall or bending over. With the collected data, the prediction of a fall could be studied and perhaps avoided.

Texte intégralRésumé :
In the reported research, a subject-specific multibody dynamics model was proposed to predict impact force induced in lateral fall of the elderly. Parameters such as anthropometric dimensions, segment masses, mass center, and mass moment of inertia that are required for constructing the dynamics model were extracted or calculated from a whole body DXA image of the subject. Governing equations of the fall process were established and computer codes were developed for solving the equations. The dynamics model was then validated by a controlled fall test using young volunteer. Good agreements between predicted and experimental results were observed, indicating that the proposed dynamics model has the capability to predict subject-specific impact force induced in fall.

All children—regardless of personal characteristics, background, or physical challenges—deserve an opportunity to learn mathematics to the best of their ability. This declaration is loud and clear, and NCTM's mission of providing sound mathematics instruction and holding high expectations for all children (NCTM 2000) is important in our mathematical world. Mathematics permeates our daily lives from the moment we awaken to the moment we fall asleep. In many ways, our mathematical successes and failures get woven into the life stories that make us who we are.

Texte intégralRésumé :
Feminists, among others, have found Eve’s representation in Milton’s Paradise Lost problematic over the last centuries. Some of them consider Eve to be Adam’s inferior while others find traces of egalitarian relationship between them. This study uses Penelope Brown and Stephen C. Levinson’s Politeness Theory and applies it to the conversations between Adam and Eve prior to the Fall in order to address this issue. It is demonstrated in this article that, before the Fall, Eve always exercises less power than Adam except for a brief moment that she achieves equality.

Texte intégralRésumé :
This article reconstructs J. G. A. Pocock's debt to Hannah Arendt's political philosophy in The Machiavellian Moment and argues that her presentation of classical politics in The Human Condition and her account of the secular nature of American foundation in On Revolution were important sources for Pocock's analysis of American liberal insecurity. However, a contextualization of The Machiavellian Moment within Pocock's immediate intellectual and professional milieu indicates that he placed himself in critical relation to Arendt's civic republican theory and located her philosophy of history in the same spectrum as the American political tradition he sought to historicize. While they did share a similar perspective on the ethical and political value of locating oneself within a long historical durée, their different conceptions of the problem of continuity for secular political structures provides a crucial context for their disparate responses to the discourse of political crisis in the United States in the late 1960s and the 1970s.

Texte intégralRésumé :
Every film has its moment. Be it an unforeseen glance, an unmotivated gesture, or a startling sequence unnecessary for narrative progression, such a "moment" reveals in a flash what's at stake—then and now. In the following, I analyze such a moment in Karl Grune's Die Strasse (The Street), a film that Siegfried Kracauer considered one of the defining documents of German modernity. Produced and shown in fall of 1923, the film inaugurated the so-called Strassenfilm genre, which combined the visual language of expressionist cinema (oblique angles, harsh lighting, heavy shadows, painted backdrops, distorted spaces, stylized gestures) with an urban setting. In its gritty exploration of sex, crime, morality, and madness, the street film became the prototype for American film noir of the 1940s. The Street has its "moment" in a brief sequence that discloses the film's underlying theoretical project—the nexus between urban modernity and the disciplining power of vision.

Texte intégralRésumé :
Gilles Deleuze and Hannah Arendt are two thinkers who have theorised the exceptionalism of the revolutionary moment. For Deleuze, it is the moment of the people to come. For Arendt, it is the moment of the freedom of political action. In the decades since the fall of the Berlin Wall there has been extensive debate on how to remember the German Democratic Republic (DDR) and how to understand the events leading up to its demise. Arendt's analyses of totalitarianism, natality and the public sphere provide points of orientation in an attempt to clarify the nature of the DDR, the dishonesty of its evaluation in the West as well as the transitory purchase of its legitimating discourse on later generations of its citizens. Deleuze's reinvigoration of the revolutionary sense of the term ‘people’ sets it in defiance of prevalent notions of popular sovereignty and therefore facilitates a different reading of the protests against the so-called people's republic of the DDR: something else was at issue besides the substitution of one state form for another.

Texte intégralRésumé :
Interest in this paper centres on two exemplary cases of two entirely different modes of dramatisation and theatrical practice which, nonetheless, share a common goal. The two works studied here aim at a critical reconsideration of the political issues which surround intensely violent events that have marked American mega cities over the past three decades. Furthermore, both plays aspire to articulate an original statement on the ways in which these issues routinely fall prey to the hegemony of monolithic and sterile media representations of urban spaces. Anna Deavere Smith’s vigorous exploration of the reserves of documentary drama and theatre in Twilight: Los Angeles, 1992 (1993) is read alongside and juxtaposed to José Rivera’s innovative and exceptional use of magic realism for the stage in Marisol (1992). The question of political efficacy in both cases is thoroughly examined here in relation to how profitably these works showcase acts of interrogating mass media appropriations of identified city riots and instances of social unrest. Attention is devoted to the ways in which Smith’s verbatim documentation of the city in turmoil as well as Rivera’s surreal and dystopian account of liminal experiences of disenfranchised urban constituents may lead audience members to reassess their own habits of negotiating political demands and relating to moments of crisis.

Texte intégralRésumé :
(1) Background: This research aimed to determine the effect of the backward fall technique on the sagittal linear acceleration of the head in students training in different sports. (2) Methods: The study involved 41 students divided into two study groups. Group A included 19 students training in martial arts who practised falls with side aligning of the body. Group B included 22 handball players who practised falls performed in a way similar to a gymnastic backward roll. A rotating training simulator (RTS) was used to force falls, and Wiva ® Science apparatus was used to assess acceleration. (3) Results: Significant changes in head acceleration were only obtained between immediate fall tests (IFTs) and forced fall tests (FFTs) in group B. Significant differences were noted between groups for the IFT and FFT. Greater changes in head acceleration were noted in group B. (4) Conclusions: Smaller changes in head acceleration in group A students indicate a lower susceptibility to head, pelvic and cervical spine injuries in falls performed backward with side aligning of the body. This technique in group A limited the differences in head acceleration between IFTs and FFTs. Negative acceleration values obtained in group B confirmed that the head may suffer a moment of force, tilting it backwards, but then forward when the buttocks hit the ground.

Based failure criteria of composite materials structural damage and simulation of finite element dynamic impact, the drop process and damage failure of composite cylinder are calculated and analysed. For composite cylinders with different wind angles falling from a height, the stresses of internal points during the impact process are obtained. Based on the value of the process stress, the failure of the cylinder is analysed. The results show that at the moment when the cylinder bounces back after impacted with the ground, the stress and strain reaches to the maximum. The maximum hoop stresses are at cylinder mouth and cylinder bottom which collide with ground. Maximum axial tensile stresses are at the central body of cylinder. The stress distribution of 13 degrees fiber angle of cylinder is slightly less than that of 25 degree. By Tsai-Wu composite failure criterion, there is no failure of the composite cylinder.

Texte intégralRésumé :
Abstract An accurate understanding of one’s abilities and limitations allows adaptive response to the challenges that are faced in daily life. However, older adults may over or under estimate their actual abilities. The Daily Balance Project examined the intraindividual dynamics of older adults’ perceived balance with objective measures of balance and physical activity. For 30 consecutive days, following a comprehensive fall risk assessment, 20 older adults rated their balance confidence (Activities Balance Confidence scale) at that moment and then performed five standardized balance assessments measured via smartphone accelerometer held to their chest. Physical activity was measured with an activity monitor. Baseline measurements of fall risk differentiated the extent of intraindividual variation and co-variation of balance and physical activity. For some participants, actual and perceived balance became more closely aligned as the study progressed. The implications of the findings for life-span perspectives on aging and fall prevention are discussed.

Texte intégralRésumé :
ABSTRACT With the present study, we introduce a fast and robust method to calculate the source displacement spectra of small earthquakes on a local to regional scale. The work is based on the publicly available Qopen method of full envelope inversion, which is further tuned for the given purpose. Important source parameters—seismic moment, moment magnitude, corner frequency, and high-frequency fall off—are determined from the source spectra by fitting a simple earthquake source model. The method is demonstrated by means of a data set comprising the 2018 West Bohemia earthquake swarm. We report moment magnitudes, corner frequencies, and centroid moment tensors inverted from short-period body waves with the Grond package for all earthquakes with a local magnitude larger than 1.8. Moment magnitudes calculated by envelope inversion show a very good agreement to moment magnitudes resulting from the probabilisitc moment tensor inversion. Furthermore, source displacement spectra from envelope inversion show a good agreement with spectra obtained by multiple taper analysis of the direct onsets of body waves but are not affected by the large scatter of the second. The seismic moments obtained with the envelope inversion scale with corner frequencies according to M0∝fc−4.7. Earthquakes of the present data set result in a smaller stress drop for smaller magnitudes. Self-similarity of earthquake rupture is not observed. In addition, we report frequency-dependent site amplification at the used stations.

Texte intégralRésumé :
Abstract With increasing computer power, explicit microphysics schemes are becoming increasingly important in atmospheric models. Many schemes have followed the approach of Kessler in which one moment of the hydrometeor size distribution, proportional to the mass content, is predicted. More recently, the two-moment method has been introduced in which both the mass and the total number concentration of the hydrometeor categories are independently predicted. In bulk schemes, the size spectrum of each hydrometeor category is often described by a three-parameter gamma distribution function, N(D) = N0Dαe−λD. Two-moment schemes generally treat N0 and λ as prognostic parameters while holding α constant. In this paper, the role of the spectral shape parameter, α, is investigated by examining its effects on sedimentation and microphysical growth rates. An approach is introduced for a two-moment scheme where α is allowed to vary diagnostically as a function of the mean-mass diameter. Comparisons are made between calculations using various bulk approaches—a one-moment, a two-moment, and a three-moment method—and an analytic bin model. It is found that the size-sorting mechanism, which exists in a bulk scheme when different fall velocities are applied to advect the different predicted moments, is significantly different amongst the schemes. The shape parameter plays an important role in determining the rate of size sorting. Likewise, instantaneous growth rates related to the moments are shown to be significantly affected by this parameter.

Texte intégralRésumé :
The eve of the ongoing Iraq war was a decisive moment for world leaders since they, given American pressure, had to choose between being with US or with the enemies. It meant treading on potentially threatening issues that could harm inter-national alliances and friendships. This paper illustrates using transcripts of Jacques Chiracs (then French president) interviews the linguistic avoidance strategies used to avoid, redefine, recontextualise, reframe, and reassess concepts and topics considered threatening to the position held. The answers Chirac gives to the rather direct questions show his desire to avoid projecting the false idea that France is hindering American foreign policy. It is therefore not only his face that is at stake, but also that of his people, his political party, and the nation. Placing the analysis within the broader concept of multimodal communication, the paper adopts some of the findings made by Caffi & Janney (1994) and Janney (1999) to emphasise that strategies of avoiding implicative and threatening concepts in speech follow similar patterns of escaping from or avoiding harmful objects in the physical world.

Texte intégralRésumé :
Abstract This paper presents a detailed analysis of convection-permitting cloud simulations, aimed at increasing the understanding of the role of parameterized cloud microphysics in the simulation of mesoscale convective systems (MCSs) in the tropical western Pacific (TWP). Simulations with three commonly used bulk microphysics parameterizations with varying complexity have been compared against satellite-retrieved cloud properties. An MCS identification and tracking algorithm was applied to the observations and the simulations to evaluate the number, spatial extent, and microphysical properties of individual cloud systems. Different from many previous studies, these individual cloud systems could be tracked over larger distances because of the large TWP domain studied. The analysis demonstrates that the simulation of MCSs is very sensitive to the parameterization of microphysical processes. The most crucial element was found to be the fall velocity of frozen condensate. Differences in this fall velocity between the experiments were more related to differences in particle number concentrations than to fall speed parameterization. Microphysics schemes that exhibit slow sedimentation rates for ice aloft experience a larger buildup of condensate in the upper troposphere. This leads to more numerous and/or larger MCSs with larger anvils. Mean surface precipitation was found to be overestimated and insensitive to the microphysical schemes employed in this study. In terms of the investigated properties, the performances of complex two-moment schemes were not superior to the simpler one-moment schemes, since explicit prediction of number concentration does not necessarily improve processes such as ice nucleation, the aggregation of ice crystals into snowflakes, and their sedimentation characteristics.

Texte intégralRésumé :
Hybrid bulk–bin microphysics schemes discretize particle size distributions into bins for calculating microphysical process rates, while retaining a limited number of bulk prognostic quantities and assuming an underlying analytic functional form for the particle size distributions as in traditional bulk microphysics schemes. In this paper, the treatment of sedimentation in two-moment bulk and hybrid schemes is compared using different numerical methods. Using the first-order upwind method for calculating sedimentation in conjunction with a widely used, two-step, time-splitting approach that updates model fields after transport by air motion followed by calculation of sedimentation, it is shown analytically that despite using a spectrum of fall speeds corresponding to different particle sizes, hybrid schemes converge with increasing bin resolution toward bulk schemes that utilize only characteristic moment-weighted particle fall speeds. While not strictly convergent, it is also shown that solutions using bulk and hybrid schemes are often similar for other numerical methods and approaches. Noticeable improvement using the hybrid scheme occurs in a few circumstances: when the Courant number associated with falling precipitation is large (>>1), requiring substepping, semi-implicit, or Lagrangian-type methods for numerical stability; or when a one-step approach is employed that calculates hydrometeor transport in a single step using a velocity that combines both vertical air motion and particle fall speed. Thus, it is concluded that the use of hybrid rather than bulk schemes is justified for some, but not all, applications, and care should be taken to determine the appropriateness of hybrid schemes for specific applications.

Texte intégralRésumé :
“Evangelicalism Before the Fall” reveals the surprising and largely forgotten world of the premillennialist wing of late Victorian Evangelicalism through a close reading of its leading paper, The Christian Herald and Signs of Our Times. Organized around five thematic soundings (“worldly affairs”; “great questions”; “self and other”; “meeting modernity”; and “Evangelical culture”), the paper shows that premillennialism comported easily with socially elite status, liberal instincts, and irenic habits of mind not commonly associated with those holding similar beliefs in the decades after. Although the primary goal of the article is to recover an overlooked moment in Evangelical history, it secondarily contributes to a historiographical debate in the field of Fundamentalism studies, where revisionists have challenged the “fall” narrative of an earlier cohort of scholars, such as George Marsden and Joel Carpenter, who documented a decline in social standing and influence for the movement relative to the late nineteenth century. The article lends support to the fall narrative, properly understood as a change in social and cultural status.

Texte intégralRésumé :
A major determinant of the risk of hip fracture in a fall from standing height is the force applied to the femur at impact. This force is determined by the impact velocity of the hip and the effective mass, stiffness, and damping of the body at the moment of contact. We have developed a simple experiment (the pelvis release experiment) to measure the effective stiffness and damping of the body when a step change in force is applied to the lateral aspect of the hip. Results from pelvis release experiments with 14 human subjects suggest that both increased soft tissue thickness over the hip and impacting the ground in a relaxed state can decrease the effective stiffness of the body, and subsequently reduce peak impact forces. Comparison between our fall impact force predictions and in-vitro measures of femoral fracture strength suggest that any fall from standing height producing direct, lateral impact on the greater trochanter can fracture the elderly hip.

Back - propagation Neural Network has weaknesses such as errors of gradient descent training slowly of error function, training time is too long and is easy to fall into local optimum. Back - propagation algorithm is one of the artificial neural network training algorithm that has weaknesses such as the convergence of long, over-fitting and easy to get stuck in local optima. Back - propagation is used to minimize errors in each iteration. This paper investigates and evaluates the performance of Adaptive Moment Estimation (ADAM) to minimize the squared error in back - propagation gradient descent algorithm. Adaptive Estimation moment can speed up the training and achieve the level of acceleration to get linear. ADAM can adapt to changes in the system, and can optimize many parameters with a low calculation. The results of the study indicate that the performance of adaptive moment estimation can minimize the squared error in the output of neural networks.

There must be recognition of the centrality of the United States to the shaping of a global order. Even those who have the most antipathy toward the United States recognize the consequence of the United States, particularly under the Trump administration. The United States presided over a world that was essentially in equilibrium since World War II. By the fall of the Berlin Wall, the United States became a unipolar power. Over the last thirty years the international community has witnessed the decline in U.S. hegemony and influence over the world. There needs to be an understanding of whether this pandemic is a moment to return to business as usual or whether this is a moment of rapture that could lead to something completely different.

Dynamic speckle imaging is one of the powerful optical techniques used for investigating the dynamical processes of biological as well as industrial materials. It is a cost effective technique and also non-invasive in nature. It possesses high temporal and spatial resolution. This paper reports the application of certain numerical algorithms for extracting the information regarding the curing process of an epoxy adhesive. Time evolution of speckle images were analyzed using statistical methods such as Normalized 2 dimensional Cross-correlation and Inertia moment. The Inertia moment was found to decrease and correlation coefficient was found to increase due to the fall in activity that resulted by the curing phenomenon. The curing time of epoxy is obtained as five minutes which is in accordance with the company literature.

Texte intégralRésumé :
Abstract The computation of hydrometeor sedimentation in one-moment, two-moment, and three-moment bulk microphysics parameterizations is examined in the context of a 1D model, with no other microphysical processes active. The solution from an analytic bin model is used as a reference against which the bulk model simulations are compared. Errors in the computed (nonprognostic) moments from 0 to 7 from the bulk model runs are examined. In addition to the commonly used predicted variables (number concentration, mass, and reflectivity), bulk scheme configurations with alternative combinations of prognostic moments are considered. While the extra degree of freedom in a two-moment scheme adds realism to the simulation of sedimentation over a one-moment scheme, the standard practice of imposing a constant relative dispersion in the particle size distribution results in considerable errors in some of the computed moments. The error can be shifted to different moments by selecting different prognostic moments. For three-moment schemes, the error is considerably reduced over a wide range of computed moments and there is much less sensitivity to the choice of prognostic variables. Two alternative approaches are proposed for modifying the computation of sedimentation in two-moment schemes to reduce problems associated with excess size sorting. The first approach uses a diagnostic relative dispersion (shape) parameter, generalized for any pair of prognostic moments. The second involves progressively reducing the differential fall velocities between the moments and is therefore applicable for schemes that hold the shape parameter constant. Both approaches greatly reduce the errors in the computed moments, including those on which microphysical process rates depend, and are easily applied to existing two-moment schemes.

Texte intégralRésumé :
Experimental testing of lightly reinforced concrete column was conducted to investigate the collapse behavior of such column under cyclic lateral loading. Six column specimens, which have low longitudinal reinforcement and lack of confinement, were detailed with no lap splice, and non-ductile lap splice within or outside critical region. Placing the short, unconfined column's lap splice within critical region caused peak moment to fall short under its nominal moment capacity. In contrast, moment capacity of the specimen containing non-ductile lap splice outside critical region was in close agreement with those of specimen without lap splice. However, its inelastic damage region was moving away from the beam-column interface, resulted in degradation of drift capacity and rapid degradation of lateral strength. The presence of non-ductile lap splice outside critical region also potentially shift column's collapse mechanism from flexure to flexure-shear critical. The ability of lightly reinforced concrete columns to maintain its axial load carrying capacity to large drift ratios despite heavy damage and significant loss of lateral load carrying capacity indicates that lap splice failure does not create sudden collapse hazard.

Texte intégralRésumé :
Abstract This paper addresses the question of the relation between mortal and immortal time in the Iliad as it is represented by the physical act of falling. I begin by arguing that falling serves as a point of reference throughout the poem for a concept of time that is specifically human. It is well known that mortals fall at the moment of death in the poem, but it has not been recognized that the movement of the fall is also connected with the time of birth, aging, and generation. In light of the significance of falling for mortals, I then go on to examine the problematic case of two particular immortals who fall in the Iliad. When Hephaestus tumbles down to earth from Olympus, and when Ares is knocked flat on the battlefield, both gods, I argue, also ““fall into”” human time. This complicates their status as ageless and eternal beings, and draws into question the different temporal registers at work in the narrative (such as repetition, ““long time,”” and time that is steady or continuous [empedos]). The single action of falling brings together several key concepts in the poem which hinge on the issue of the separation between the mortal and immortal spheres in the Iliad.
