Published: July 2021

The article traces the development of eight years of “Music and Resilience,” a project of international cooperation between a Palestinian NGO in Lebanon and an Italian CBO, with the aim of building music resources with, and for, the refugee communities of Lebanon.
Supported epistemologically by ethnography, sociology, psychology, and community music pedagogy, the paper narrates and analyzes the project's development as a multi-layered, organically orientated response to the specific geopolitical and social context, in which continuous monitoring and evaluation inform the necessary “adjustments” of the project's “pitch.” Using the paradigm of Action Learning within the framework of Theory of Social Change, the authors draw on the experience and research “Music and Resilience” has stimulated, to identify some “cardinal points” relevant to cross-cultural cooperation in general.

Significance Statement
Among the general population, infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) robustly protects against subsequent reinfection. Whether this finding extends to patients with ESKD was not previously known. Here, we prospectively studied patients treated with hemodialysis in the United States, and compared SARS-CoV-2 infection rates among patients with and without evidence of prior SARS-CoV-2 infection (either baseline antibodies or history of disease). We found that although prior SARS-CoV-2 infection protected against subsequent reinfection, the effect was not as strong as in the general population. This study indicates that prior infection with SARS-CoV-2 provides incomplete protection in patients with ESKD, and argues in favor of prioritizing such patients for vaccination regardless of prior infection status.

Background
Although reinfection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is rare among individuals with few coronavirus disease 2019 (COVID-19) risk factors, the ability of naturally acquired immunity to prevent reinfection among patients with ESKD is not known.

Methods
This prospective study was conducted among adults with ESKD treated with in-center hemodialysis (ICHD) in the United States. Exposure was ascribed on the basis of the presence or absence of IgG against SARS-CoV-2 at baseline, and separately, a history of documented COVID-19 before study entry. Outcomes were assessed after an infection-free period, and were any SARS-CoV-2 infection (i.e., detected by protocolized PCR tests or during routine clinical surveillance), and clinically manifest COVID-19 (consisting of only the latter).

Results
Of 2337 consented participants who met study inclusion criteria, 9.5% were anti–SARS-CoV-2 IgG positive at baseline; 3.6% had a history of COVID-19. Over 6679 patient-months of follow-up, 263 participants had evidence of any SARS-CoV-2 infection, including 141 who had clinically manifest COVID-19. Presence of anti–SARS-CoV-2 IgG (versus its absence) at baseline was associated with lower risk of any SARS-CoV-2 infection (incidence rate ratio, 0.55; 95% confidence interval, 0.32 to 0.95) and clinically manifest COVID-19 0.21 (95% confidence interval, 0.07 to 0.67).

Conclusion
Among patients with ESKD, naturally acquired anti–SARS-CoV-2 IgG positivity is associated with a 45% lower risk of subsequent SARS-CoV-2 infection, and a 79% lower risk of clinically manifest COVID-19. Because natural immunity is incomplete, patients with ESKD should be prioritized for SARS-CoV-2 vaccination, independent of their COVID-19 disease history.
Ikhin Tone and Nasality: Autosegmental Effects
Authors: A. Oladimeji Olaide , T. Opoola Bolanle 
Published: July 2021

In generative phonology, tone and nasality are described as suprasegmental phonological units. This implies that their survival depends on the segments on which they are grounded. Thus, when a tone bearing unit or nasality bearing unit disappears, any of these segments also disappears. In autosegmental theory, however, tone or nasality survives after the deletion of segment to which it is attached. This phenomenon is termed ‘stability’ which is the foundation for autosegmental phonological theory. Stability is the survival of tone and nasality after the deletion of segments on which they are grounded. Tone and nasality exhibit stability in Ikhin, a North-Central Edoid language spoken in Edo State, South-South, Nigeria. Previous study on Ikhin dwells mainly on the phonetics of the language. This study, therefore, investigates phonological processes such as vowel elision, glide formation and nasalization with a view to determining the stability or otherwise of tone and nasality. This paper confirms that in Ikhin, any process that involves the removal of a tone bearing unit must relate to stability and relate to the creation of contour tones. The study further confirms that nasality remains stable even in the absence of segment to which it is linked. Based on available data, it is argued that the deletion of a Tone Bearing Unit (TBU) or a Nasality Bearing Unit (NBU) does not necessarily involve the deletion of tone or nasality. Infact, it usual does not. The study concludes that tone and nasality are independent segments. They are as independent as consonant and vowel.

Common Practices in the Creation of Educational Videos
Authors: I. Scagnoli Norma , Graham-Rent Susan M. 
Published: July 2021

Goal: To present an analysis of production and common uses of educational video in online higher education courses.
Method: This research followed a qualitative inquiry approach, and data came from three sources: secondary data from communication logs during faculty training; analysis of 320 videos in business education and their course designs, and literature review.
Results: The use of videos for education, also known as video-lectures, started to be widely used for online and hybrid university classes in the last 10 years. The practice grew with the appearance of the Massive Open Online Course (MOOC) movement in the early 2010s, and became normal during the pandemic in 2020, when some classes incorporated the use of mini-lectures together with, or instead of, synchronous online classes. The use of pre-recorded video is not new, but it is definitely a practice for which none or very few instructors received training as they were preparing to become university professors.
Contribution: This article aims to demystify the creation of educational videos by sharing what are common practices in the creation of video-lectures, and how to prepare for a successful “on-camera” experience.
Dynamic plane-strain shear rupture with a slip-weakening friction law calculated by a boundary integral method
Authors: Andrews D. J. 
Published: July 2021

AbstractA numerical boundary integral method, relating slip and traction on a plane in an elastic medium by convolution with a discretized Green function, can be linked to a slip-dependent friction law on the fault plane. Such a method is developed here in two-dimensional plane-strain geometry. The method is more efficient for a planar source than a finite difference method, and it does not suffer from dispersion of short wavelength components. The solution for a crack growing at constant velocity agrees closely with the analytic solution, and the energy absorbed at the smeared-out crack tip in the numerical calculation agrees with energy absorbed at the analytic singularity. Spontaneous plane-strain shear ruptures can make a transition from sub-Rayleigh to near-P propagation velocity. Results from the boundary integral method agree with earlier results from a finite difference method on the location of this transition in parameter space. The methods differ in their prediction of rupture velocity following the transition. The trailing edge of the cohesive zone propagates at the P-wave velocity after the transition in the boundary integral calculations.
Linear inversion of transmitted acoustic wave fields for three-dimensional modulus and density perturbations using a born-type approximation
Authors: Stauber Douglas A. 
Published: July 2021

Abstract
A Born approximation is used to linearize the relationship, in the horizontal-wavenumber and frequency domains, between lateral perturbations of modulus and density in a layered half-space and the acoustic wave field observed at the surface when a plane wave is incident from below. The resulting equations can be used to perform a linear inversion of observed acoustic wave fields to obtain lateral perturbations in modulus and density. Since modulus and density effects are separated, gravity observations can be included in the inversion procedure without any assumptions about the relationship between density and acoustic velocity. Tests with synthetic data sets reveal that the inversion method gives useful results when the spatial scales of the inhomogeneities are smaller than several acoustic wavelengths. The inclusion of gravity observations in the inversion reduces the strong negative tradeoff between modulus and density perturbations.
Constraints on explosive sources with spall from near-source waveforms
Authors: Stump Brian W. 
Published: July 2021

AbstractSpall, the tensile failure of a material due to high stress loading, has been observed in a number of contained and surface explosions. The phenomenon results in a repartition of the initial spherical explosion energy source, yielding a second energy source which is cylindrical and delayed in time. Recent spall models by Day et al. (1983) demanding conservation of momentum have shown the phenomenon to have little contribution to 20-sec surface waves. These models are extended to include the effect of the process on near-source seismograms. The spall model is constrained by observations within the nonlinear regime of the source which bound the mass, momentum, and timing of the process. Comparison of these forward models with the inverse vertical point force source inferred from seismic recordings of a bermed surface explosion yields excellent agreement. The spall model developed from the contained explosion, CHEAT, is used to create synthetic seismograms. Comparisons of these waveforms with those from a Mueller-Murphy contained explosion indicate that the waveform contribution from spall is similar in size to the spherical explosion waveform. The complete synthetic composed of the spall and explosion contribution compares favorably with observational data from the CHEAT experiment in both amplitude and energy distribution.
Model calculations of regional network locations for earthquakes in subduction zones
Authors: McLaren James P. , Frohlich Cliff 
Published: July 2021

AbstractAlgorithms for locating earthquakes recorded by local networks commonly assume a flat-layered velocity structure, even in island arc regions where the presence of a dipping lithospheric slab introduces large lateral velocity variations. Moreover, because seismic stations occur along the narrow island arc, the resulting linear network geometry degrades earthquake location. To model this situation, we trace rays in a spherical earth from hypothetical earthquakes through appropriate velocity models to networks of various geometries. To isolate the effect of the slab, most of the velocity models consist simply of a planar-dipping constant velocity region embedded in a sphere with a constant lower seismic velocity. We then use the calculated P and S travel times to relocate the hypothetical earthquakes with a flat-layered velocity structure. We perform calculations of this kind in a variety of models, varying the dip of the slab, the velocity contrast between the slab and the mantle, the station geometry, and the distance between the earthquakes and the slab-mantle boundary. We also perform calculations in more realistic models with geometry closely resembling two seismic networks in Alaska.These model calculations emphasize the great care that seismologists should exercise when interpreting local network locations in island arc regions. In the present study, all the relocations incorporate P and S arrivals at all stations, and include no random or “picking” errors. Nevertheless, the relocated hypocenters differ from the “actual” model hypocenters by up to 100 km or more and produce significant distortions in the Wadati-Benioff zone. The most prominent spurious feature is a clear increase in the apparent dip of the Wadati-Benioff zone beneath a certain depth. Furthermore, the relocation reduces the width or apparent thickness of the Wadati-Benioff zone, e.g., they produce an apparent thickness of 5 km or smaller for a zone of earthquakes with an “actual” thickness of 20 km. However, if different combinations of stations report different events, it is possible to determine an apparent thickness which exceeds the “actual” thickness.For local networks near subduction zones, it is useful to estimate the mislocation and rms residual expected for each event recorded and located. This can be accomplished by performing model calculations in a simple model with a constant velocity, dipping slab embedded in a half-space. For such a simple model, there exists only one ray path from each earthquake within the slab to each station, and the travel time for this path can be calculated as a part of the routine network location process. A relocation using the routine network location algorithm and these calculated travel times provides an indication of the expected mislocation and rms residual for the actual recorded event.
Upthrow of objects due to horizontal impulse excitation
Authors: Psycharis Ioannis N. , Jennings Paul C. 
Published: July 2021

Abstract
The phenomenon of upthrow of rigid blocks, excited into motion by horizontal impulses, is examined in this study. A simple foundation model is used, consisting of two sets of springs and dashpots; one set near each corner of the block. Each set consists of vertical and horizontal elements. The vertical springs are not permitted to take tensile forces, so separation of the block from the ground is allowed. The associated horizontal spring separates along with the vertical spring. The response can be separated into three regimes, namely, full contact, partial uplift, and complete separation. Analytical expressions for the response are given for the first two cases; the third case is simply rigid body motion. The overall response is nonlinear and analytical criteria for upthrow were not found. The minimum value of the impulse required for complete separation, expressed as a normalized initial velocity, was determined numerically and a parametric investigation performed. Although the irregularity of the results does not allow many general conclusions to be drawn, it was found that for short blocks, a decrease in the stiffness of the horizontal foundation springs required larger impulses for separation. These effects had mixed results for tall blocks.
Source parameters of the 28 October 1983 Borah Peak, Idaho, earthquake from body wave analysis
Authors: Doser Diane I. , Smith Robert B. 
Published: July 2021

AbstractModeling of long-period body waves of the MS = 7.3 Borah Peak, Idaho, earthquake suggests that the earthquake was a simple rupture that nucleated at a depth of about 16 km and propagated unilaterally northwestward toward the surface. The seismic moment tensor obtained from the inversion of teleseismic body wave amplitude data agrees well with the fault plane solution obtained from short-period first motion data (strike, 138 ± 3°; dip, 45 ± 3°; rake, −60 ± 5°) and the observed surface faulting. The scalar double couple moment of 2.1 × 1026 dyne-cm obtained from the inversion is comparable to a moment of 1.4 × 1026 dyne-cm estimated from the observed surface faulting. Estimates of stress drop based on these values for the moment are 17 to 12 bars, respectively.
Frequency-dependent attenuation in the crust beneath Central France fromLgwaves: Data analysis and numerical modeling
Authors: Campillo Michel , Plantet Jean-Louis , Bouchon Michel 
Published: July 2021

AbstractThe quality factor of shear waves in the crust beneath Central France is evaluated by the combined use of data analysis and theoretical modeling. The measurement is made from Lg wave records of 18 earthquakes at 22 short-period vertical seismic stations of the French seismic network. The geometrical attenuation of Lg waves has been calculated through a numerical simulation in a perfectly elastic model. The station responses (including site effects) have been evaluated from Lg waves and from records of the seismic noise. Q has been calculated for a set of 11 frequencies between 0.5 and 10 Hz and has been found to be in the formQ = 290 * f 0.52where f is the frequency. The numerical simulation leads to the interpretation of Q of Lg waves as the mean value of Q within the crust. Theoretical and experimental decay of energy with distance are in very good agreement. The Lg waves present a different sensitivity to a low Q zone whether this zone is associated with the sediments or with scattering in the lower crust. The lower crust beneath central France appears from our experimental results to be associated with high values of Q.
