Digital Discourse Genres in English L2: Types and Pedagogy
Creators: name: Vazquez-Calvo, Boris
Publisher: name: Zenodo
Year: 2023
Subjects: digital discourse genres, digital literacies, social media, English L2 pedagogy, bridging activities

description: In our digitized era, diverse digital genres have emerged, redefining traditional discourse (Herring & Androutsopoulos, 2015; Vazquez-Calvo & Cassany, 2022). This evolution calls for educators to deeply understand and integrate these genres into the English-L2 teaching framework, ensuring students achieve linguistic proficiency while being culturally, communicatively, and digitally competent. This workshop endeavors to navigate this intersection of digital genre and English L2 pedagogy. “Part 1: Decoding the digital discourse” delves deep into the unique characteristics and typologies of digital discourse genres. Participants will embark on a journey transitioning “From paper to pixels,” comprehending the essence of digital texts from tweets to vlogs. Through a meticulous breakdown, we will uncover the textual traits that mark online discourse, such as brevity or multimodality, as well as the communicative dynamics that drive it, such as real-time feedback and interaction. We will do so by examining our own and others’ practices through guided interactive activities. In essence, we set the stage, highlighting the rise and significance of the digital realm in contemporary communication. While “Part 1: Decoding the digital discourse” introduces the foundational elements of digital genres, “Part 2: Teaching digital discourse genres for English-L2” shifts the focus to pragmatic classroom applications. How can educators effectively teach these digital genres in the English-L2 classroom? An acceptable answer lies in effective lesson planning. Borrowing from the principles of backward design (Tomaswick, 2018) and bridging activities (Thorne & Reinhardt, 2008), we will guide participants on crafting lessons that are not only linguistically enriching but also digitally empowering. A highlight of this section will be a hands-on group reflection activity titled “Crafting a Bridge,” where participants will be prompted to brew initial ideas on a lesson where a digital genre is the final product. The aim? Bridging twin outcomes for learners is key: targeting communicative proficiency and digital literacy at the same time. By the workshop’s end, participants will have started crafting a foundational toolkit for deeper exploration of text typology and variation in English. This will enable them to seamlessly incorporate both digital and traditional discourse genres into their English-L2 teaching practices as they continue their academic pursuits and beyond.

description: Spectral and time dependent surface photovoltage (SPV) measurements were performed on
Cu2ZnSn(SxSe1-x)4 (CZTSSe) thin films prepared on ITO/glass substrates by spray pyrolysis at ambient atmosphere
from aqueous solutions and subsequent selenization of Cu2ZnSnS4 (CZTS) layers. The morphology, stoichiometry
and phases of the crystalline thin films were studied by electron microscopy, energy dispersive x-ray analysis and xray
diffraction, respectively. The CZTSSe thin films show mostly the kesterite type CZTSSe phases and are slightly
copper deficient. The Se/(S+Se) ratio amounted to about 0.27. The onset energies of SPV signals were observed at
about 1.0 and 1.5 eV. The transition at 1.0 eV can be attributed to the SnSe secondary phase with an indirect band
gap of 0.90 eV. The energy of 1.5 eV corresponds to the band gap of the CZTSSe with about 25 % of Se content. A
slow relaxation process and a change of the sign set on at photon energies above 1.5 eV. Results are discussed in
relation to the phase analysis.

description: This article presents an analysis of the normalized Yamabe flow starting at and preserving a class of compact Riemannian manifolds with incomplete edge singularities and negative Yamabe invariant. Our main results include uniqueness, long-time existence and convergence of the edge Yamabe flow starting at a metric with everywhere negative scalar curvature. Our methods include novel maximum principle results on the singular edge space without using barrier functions. Moreover, our uniform bounds on solutions are established by a new ansatz without in any way using or redeveloping Krylov-Safonov estimates in the singular setting. As an application we obtain a solution to the Yamabe problem for incomplete edge metrics with negative Yamabe invariant using flow techniques. Our methods lay groundwork for studying other flows like the mean curvature flow as well as the porous medium equation in the singular setting.

description: Nanoscale metal oxide memristors have potential in the development of brain-inspired computing systems that are scalable and efficient1-3. In such systems, memristors represent the native electronic analogues of the biological synapses. However, the characteristics of the existing memristors do not fully support the key requirements of synaptic connections: high density, adjustable weight, and low energy operation. Here we show a bilayer memristor that is forming-free, low-voltage (~|0.8V|), energy-efficient (full On/Off switching at ~2pJ), and reliable. Furthermore, pulse measurements reveal the analog nature of the memristive device, that is it can be directly programmed to intermediate resistance states. Leveraging this finding, we demonstrate spike-timing-dependent plasticity (STDP), a spike-based Hebbian learning rule4. In those experiments, the memristor exhibits a marked change in the normalized synaptic strength (>30 times) when the pre- and post-synaptic neural spikes overlap. This demonstration is an important step towards the physical construction of high density and high connectivity neural networks.

description: The solid state selenium element was used as Se sources instead of H2Se gas. It has the advantages of
non-toxic and low cost. Three-step selenization with selenium element sources is used to selenize the
electrodeposited Cu/Ga/In precursors to study the Ga distribution in CIGS thin films. A strong correlation is observed
between 1st step selenization and the Ga distribution. The Se vacancy possibly provides a Ga diffusion channel to
surface when the selenization is not enough in 1st step selenization. In this time, the Ga element exists in the metal
alloy of Cu/Ga or the binary phase of GaSe2. The Ga diffusion is very difficult when the selenization is high enough
(i.e., high Se/(Cu+In+Ga) ratio) or a stable ternary phase of CuGaSe2 is formed in 1st step selenization. The 2nd anneal
step produces the Ga diffusion and significant grain growth. The 3rd selenization step can adjust the Se content and
does not cause the Ga diffusion in CIGS thin films.

description: Cu2ZnSnS4 (CZTS) thin films were synthesized by spin coating on soda lime glass (SLG) substrates and SLG
substrates covered by molybdenum using the sol-gel method, without a further sulfurization step. The thin films were
subsequently annealed under different temperature ranging from 350°C to 550°C for 1h in a nitrogen N2 gas atmosphere.
The effect of the annealing temperature on the properties of CZTS was systematically investigated. X-ray Diffraction (XRD)
studies revealed that the as-deposited films and those annealed present the (112), (220), and (312) diffraction peaks that are
characteristic of the kësterite phase. The optimum temperature annealing found to be 470°C, and the crystallite size increases
with annealing temperature. The band gap energy of CZTS thin films changed in the range of the 1.85eV to 1.48eV upon
varying the annealing temperature. The first SLG/Mo/CZTS/ CdS/i-ZnO/AZO/Al-grid solar cells that were fabricated
showed an open-circuit voltage of 140 mV and short-circuit current of 0.63mA/cm2. These results demonstrate the CZTS
thin films can be successfully deposited by a low cost sol-gel technique.

description: We report the discovery of an optical Einstein Ring in the Sculptor constellation, IAC J010127-334319, in the vicinity of the Sculptor Dwarf Spheroidal Galaxy. It is an almost complete ring ($\sim 300^{\circ}$) with a diameter of $\sim 4.5\, {\rm arcsec}$. The discovery was made serendipitously from inspecting Dark Energy Camera (DECam) archive imaging data. Confirmation of the object nature has been obtained by deriving spectroscopic redshifts for both components, lens and source, from observations at the $10.4$ m Gran Telescopio CANARIAS (GTC) with the spectrograph OSIRIS. The lens, a massive early-type galaxy, has a redshift of ${\rm z}=0.581$ while the source is a starburst galaxy with redshift of ${\rm z}=1.165$. The total enclosed mass that produces the lensing effect has been estimated to be ${\rm M_{tot}=(1.86 \pm 0.23) \,\cdot 10^{12}\, {\rm M_{\odot}}}$.

We show that a generic knotted wire has a magnetic line of the same knot type, but that given any pair of knots there is a wire isotopic to the first knot having a magnetic line isotopic to the second. These questions can be traced back to Ulam in 1935.

description: Zinc sulfide ZnS and oxygentated zinc sulfide Zn(S,O) thin films were deposited on glass substrates by radio frequency
(RF) sputtering from zinc sulfide target in an Ar/O2 atmosphere with various oxygen proportions varying from 0 to 20%.
The RF-power was also varied between 100W to 250 W.
The ZnS films deposited in the absence of oxygen films show a nearly stoichiometric composition with a preferred
orientation along the (111) direction of the sphalerite cubic phase as revealed in the X-ray diffraction (XRD).The UVvisible-
NIR measurements showed that the films have more than 80% transmission in the visible wavelength range (395-
695 nm), while the optical band gap increased slightly from 3.44 eV to 3.58 eV as the rf-power is increased from 100 to
250 W at fixed Argon pressure of 10-2 mbar.
In the presence of oxygen in the sputtering atmosphere, the films became amorphous and it is found that the ban gap
increased to 4.2 eV for 5% oxygen.

description: While it is being debated whether Cd vacancy is an effective p-dopant in CdTe, and whether CdTe thin
film in solar energy application should be Cd-deficient or Cd-rich, in the theory of CdTe physical vapor deposition
(PVD) it has been assumed that both the source material and the thin film product is stoichiometric. In reality, the
source materials are usually not ideal. To remediate the lack of effective theory, a new PVD model for CdTe
photovoltaic (PV) modules is presented in this work based on the experimental results, in which the composition of
the CdTe thin film under growth is a parameter determined by the source CdTe composition as well as the growth
condition. The solid phase Cd1-xTex compound under deposition temperature is treated as a solid solution with a mole
of excess pure Te or Cd as solute and one mole of congruently grown CdTe as solvent. Assuming that the vapor
pressure of Te2 can be calculated by using the law of solid solution around the congruent composition. The partial
pressures also can be calculated by fitting of the experimental data assuming constant Gibbs free energy. Thus, the
mole fraction of solute in the grown CdTe thin film as well as the growth rate, as a function of the solute mole
fraction in the source CdTe can be determined.

description: Many remarkably robust, rapid and spontaneous self-assembly phenomena in nature can be modeled geometrically starting from a collection of rigid bunches of spheres. This paper highlights the role of symmetry in sphere-based assembly processes. Since spheres within bunches could be identical and bunches could be identical as well, the underlying symmetry groups could be of large order that grows with the number of participating spheres and bunches. Thus, understanding symmetries and associated isomorphism classes of microstates correspond to various types of macrostates can significantly reduce the complexity of computing entropy and free energy, as well as paths and kinetics, in high dimensional configuration spaces. In addition, a precise understanding of symmetries is crucial for giving provable guarantees of algorithmic accuracy and efficiency in such computations. In particular, this may aid in predicting crucial assembly-driving interactions. This is a primarily expository paper that develops a novel, original framework for dealing with symmetries in configuration spaces of assembling spheres with the following goals. (1) We give new, formal definitions of various concepts relevant to sphere-based assembly that occur in previous work, and in turn, formal definitions of their relevant symmetry groups leading to the main theorem concerning their symmetries. These previously developed concepts include, for example, (a) assembly configuration spaces, (b) stratification of assembly configuration space into regions defined by active constraint graphs, (c) paths through the configurational regions, and (d) coarse assembly pathways. (2) We demonstrate the new symmetry concepts to compute sizes and numbers of orbits in two example settings appearing in previous work. (3) We give formal statements of a variety of open problems and challenges using the new conceptual definitions.

description: Sequence comparison is a basic task to capture similarities and differences between two or more sequences of symbols, with countless applications such as in computational biology. An alignment is a way to compare sequences, where a giving scoring function determines the degree of similarity between them. Many scoring functions are obtained from scoring matrices. However,not all scoring matrices induce scoring functions which are distances, since the scoring function is not necessarily a metric. In this work we establish necessary and sufficient conditions for scoring matrices to induce each one of the properties of a metric in weighted edit distances. For a subset of scoring matrices that induce normalized edit distances, we also characterize each class of scoring matrices inducing normalized edit distances. Furthermore, we define an extended edit distance, which takes into account a set of editing operations that transforms one sequence into another regardless of the existence of a usual corresponding alignment to represent them, describing a criterion to find a sequence of edit operations whose weight is minimum. Similarly, we determine the class of scoring matrices that induces extended edit distances for each of the properties of a metric.

description: We report on a design and a nc-Si material combination, that together, mitigate against absorber
defect formation, and allow the utilization of 46% of the photons with E ≥1.1eV impinging on a 400nm thick nc-
Si absorber. This utilization percentage can be compared against our previous 49% result for 700nm nc-Si
nanostructured cells. The currently fabricated cells have photocurrents that are hampered by back Ag
coverage, TCO series resistance, and poor fill factors. FIB FESEM studies show these latter two issues are
not due to defects in the nc-Si, a problem which had dominated in our previous work but which has been
overcome by the use of our newest design and LPICM-CNRS nc-Si material. This FIB cross-section FESEM work also
shows the very solvable back Ag non-uniformity. Light J-V as well as dark J-V characterization allow the quantification
of the reverse bias dependence and poor fill factor behavior which are shown to have their origins in these Ag deposition
discontinuities as well as in series resistance issues. Computer studies have guided our work in developing this ultra-thin
nc-Si light and carrier collection management (LCCM) design. We discuss this modeling and our remaining problems,
solutions, and expectations for our LCCM design.

description: Quantum spin liquids may be considered "quantum disordered" ground states of spin systems, in which zero point fluctuations are so strong that they prevent conventional magnetic long range order. More interestingly, quantum spin liquids are prototypical examples of ground states with massive many-body entanglement, of a degree sufficient to render these states distinct phases of matter. Their highly entangled nature imbues quantum spin liquids with unique physical aspects, such as non-local excitations, topological properties, and more. In this review, we discuss the nature of such phases and their properties based on paradigmatic models and general arguments, and introduce theoretical technology such as gauge theory and partons that are conveniently used in the study of quantum spin liquids. An overview is given of the different types of quantum spin liquids and the models and theories used to describe them. We also provide a guide to the current status of experiments to study quantum spin liquids, and to the diverse probes used therein.

description: Oxygenated cadmium sulfide (CdS:O) thin films have been prepared by reactive RF magnetron
sputtering with varying the O partial pressure from 0.08 mTorr to 0.18 mTorr. The quantitative results from the X-ray
photoelectron spectroscopy (XPS) show that the relative concentration of oxygen atoms increases considerably with O
partial pressure and O atoms are mostly combined with the S atoms to form SO4 complexes. The bandgap of the films
were found in the range of 2.65 eV-2.74 eV.The film’s crytallinity was observed to reduce with the increase of O
partial pressure. The complete cell was fabricated by sputtering technique with a novel configuration of
‘glass/FTO/ZnO:Sn/CdS:O/CdTe/Cu:C/Ag’. The performances of the ultra-thin cells (CdTe ~ 1μm) were evaluated
under illumination of 1.5 AM, and the efficiency of 10.27% was achieved so far.

description: ZnxCd1-xS thin films at low zinc content for a possible usage as window layer in CdTe thin film solar
cells were deposited on bare soda lime glass substrates by RF magnetron co-sputtering of CdS and ZnS at different
deposition temperatures. The deposition temperature was varied against several parameters, until best film
characteristics were obtained. The composition of the thin films was controlled by varying the RF power of CdS and
ZnS in such a ratio so that the zinc content in the thin films remained low. The structural, optical and surface
morphological properties of the films were investigated using energy dispersive X-ray analysis (EDX), X-ray
diffraction pattern (XRD), UV-Vis spectroscopy and scanning electron microscopy (SEM). The crystallinity of the
films increased with increasing deposition temperature. The optical absorption and transmission spectra were
recorded within the range 300-900 nm. The band gap of thin films showed slight decreasing trend for higher
deposition temperature. From SEM, it was found that the thin films were formed by different clusters of grains which

temperature has significant influence on the ZnxCd1-xS thin film properties grown by RF magnetron co-sputtering.

description: Observations of the epoch of reionization give us clues about the nature and evolution of the sources of ionizing photons, or early stars and galaxies. We present a new suite of structure formation and radiative transfer simulations from the PRACE4LOFAR project designed to investigate whether the mechanism of radiative feedback, or the suppression of star formation in ionized regions from UV radiation, can be inferred from these observations. Our source halo mass extends down to $10^8 M_\odot$, with sources in the mass range $10^8$ to $10^9 M_\odot$ expected to be particularly susceptible to feedback from ionizing radiation, and we vary the aggressiveness and nature of this suppression. Not only do we have four distinct source models, we also include two box sizes (67 Mpc and 349 Mpc), each with two grid resolutions. This suite of simulations allows us to investigate the robustness of our results. All of our simulations are broadly consistent with the observed electron-scattering optical depth of the cosmic microwave background and the neutral fraction and photoionization rate of hydrogen at $z\sim6$. In particular, we investigate the redshifted 21-cm emission in anticipation of upcoming radio interferometer observations. We find that the overall shape of the 21-cm signal and various statistics are robust to the exact nature of source suppression, the box size, and the resolution. There are some promising model discriminators in the non-Gaussianity and small-scale power spectrum of the 21-cm signal.

description: Cadmium Telluride (CdTe) is one of the promising photovoltaic materials for solar cell. The post
deposition treatment is important to improve the structural, electrical and optical properties of the CdTe thin films.
Hence comparative study between the thermal annealing and laser annealing was carried out is this study. The
analysis portrayed important features of both the thermal annealing and laser annealing processes and both of them
improved the film quality. The films were deposited by radio frequency magnetron sputtering in high vacuum
condition for 90 minutes at a growth temperature of 300°C. The CdTe thin films were then subjected to post
deposition thermal and laser annealing independently. Thermal annealing was done for 15 minutes at a temperature of
400°C in vacuum condition. Laser annealing was done by illuminating the films with laser beam of 532nm
wavelength with laser output energy of 60J/pulse, frequency of 10Hz and stage velocity of 0.5mm/sec. The structural
analysis from XRD showed improvement in crystallinity for both the annealing process. Topography images revealed
that thermal annealing reduced the surface roughness by improving the grain size. Optical analysis showed that the
films had good absorbance within the visible range and the band gap ‘Eg’ for the as-grown and annealed films was
approximately 1.5eV. Electrical analysis revealed that the bulk concentration improved after laser annealing and the
resistivity reduced after thermal annealing was performed on the CdTe thin films.
A New Spatio-Spectral Morphological Segmentation For Multi-Spectral Remote-Sensing Images

description: A general framework of spatio-spectral segmentation for multi-spectral images is introduced in this paper. The method is based on classification-driven stochastic watershed (WS) by Monte Carlo simulations, and it gives more regular and reliable contours than standard WS. The present approach is decomposed into several sequential steps. First, a dimensionality-reduction stage is performed using the factor-correspondence analysis method. In this context, a new way to select the factor axes (eigenvectors) according to their spatial information is introduced. Then, a spectral classification produces a spectral pre-segmentation of the image. Subsequently, a probability density function (pdf) of contours containing spatial and spectral information is estimated by simulation using a stochastic WS approach driven by the spectral classification. The pdf of the contours is finally segmented by a WS controlled by markers from a regularization of the initial classification.

description: Cu2ZnSnSe4 (CZTSe) thin films are prepared by the electrodeposition of stack copper/tin/zinc
(Cu/Sn/Zn) precursors, followed by three-step selenization at low Se pressure. The Sn loss and the formation of
molybdenum diselenide of CZTSe thin films under low Se pressure are studied. It is found that the Sn loss and the
formation of molybdenum diselenide in CZTSe thin films can be neglected by using three-step selenization at low Se
pressure. The 1st selenization leads to fine grain microstructure. The 2nd anneal step produces significant grain growth.
The 3rd selenization step adjusts the composition of thin films. After properly controlling the selenization parameters,
the efficiency of as high as 8.2% in CZTSe solar cells can be obtained by this low-cost preparation method.
The Nucleus of the Planetary Nebula EGB 6 as a Post-Mira Binary

description: EGB 6 is a faint, large, ancient planetary nebula (PN). Its central star, a hot DAOZ white dwarf (WD), is a prototype of a rare class of PN nuclei associated with dense, compact emission-line knots. The central star also shows excess fluxes in both the near- (NIR) and mid-infrared (MIR). In a 2013 paper, we used Hubble Space Telescope (HST) images to show that the compact nebula is a point-like source, located 0".16 (~118 AU) from the WD. We attributed the NIR excess to an M dwarf companion star, which appeared to coincide with the dense emission knot. We now present new ground-based NIR spectroscopy, showing that the companion is actually a much cooler source with a continuous spectrum, apparently a dust-enshrouded low-luminosity star. New HST images confirm common proper motion of the emission knot and red source with the WD. The I-band, NIR, and MIR fluxes are variable, possibly on timescales as short as days. We can fit the spectral-energy distribution with four blackbodies (the WD, a ~1850 K NIR component, and MIR dust at 385 and 175 K). Alternatively, we show that the NIR/MIR SED is very similar to that of Class 0/I young stellar objects. We suggest a scenario in which the EGB 6 nucleus is descended from a wide binary similar to the Mira system, in which a portion of the wind from an AGB star was captured into an accretion disk around a companion star; a remnant of this disk has survived to the present time, and is surrounded by gas photoionized by UV radiation from the WD.

description: High-efficiency silicon solar cells, like the silicon heterojunction cell with thin intrinsic layers (HIT) [1, 2],
use transparent conductive oxides (TCO) as anti-reflection layers. The production of these layers using sputtering
technology can cause damage to the underlying layers. This damage can be seen in a degradation of the surface
passivation properties. With the help of various protections against different damage causes we analyzed the origin of the
sputter damage. We also investigated the different degradation behavior of single layer intrinsic amorphous silicon layers
((i) a-Si) and p/n-doped silicon layers on top of intrinsic amorphous silicon layers as stacks. The influence of the intrinsic
passivation layer thickness on the amount of degradation was also investigated. The results show that a doped layer can
protect the intrinsic layer from sputter damage. The damage itself is caused by plasma photons in the range of 2.5 to 4.15
eV.

description: Zinc oxide thin films with same boron doping level and different thicknesses (ZnO:B) are prepared by
low pressure chemical vapor deposition (LPCVD) technique and implemented in thin film silicon solar cells as front
and back electrodes. The optical and electrical properties of ZnO:B films are systematically investigated through a
post heat treatment in hydrogen and vacuum atmospheres at different annealing temperatures of 160, 180, 200 and
220 °C. It is found that the optical properties, total transmission (TT) and haze value, of these films do not change at
wavelength range from 300 to 1500nm after annealed treatment, nether in hydrogen or in vacuum atmosphere.
However, the conductivity of ZnO:B films shows a remarkable increase after hydrogen annealing and a half decrease
after the vacuum treatment, respectively. The conductivity changes variously with different thermal treating
atmosphere, which are attributed to the variation of the carrier mobility of ZnO:B films by hydrogen and vacuum
annealing treatment. Amorphous silicon thin film solar cells fabricated on the thinner ZnO:B films by a post
hydrogen annealing treatment exhibit higher efficiency by 0.26% than ones on thicker ZnO:B films, which is mainly
due to increased short-circuit current. The result in this paper provides a novel way to optimize electrical properties of
thin ZnO:B films, which can lead to an increase in light-generated current and resulting a higher cell efficiency due to
the enhancement of TT when thin-annealed ZnO:B films work as front contact in silicon thin film solar cells.

description: The stability of demixing phase transition in binary mixtures of hard plates (with thickness L and diameter D) and hard spheres (with diameter $σ$) is studied by means of Parsons-Lee theory. The isotropic-isotropic demixing, which is found in mixtures of large spheres and small plates, is very likely to be preempted by crystallization. In contrast, the nematic-nematic demixing, which is obtained in mixtures of large plates and small spheres, can be stabilized at low diameter ratios ($σ$/D) and aspect ratios (L/D). At intermediate values of $σ$/D, where the sizes of the components are similar, neither the isotropic-isotropic nor the nematic-nematic demixing can be stabilized, but a very strong fractionation takes place between a plate rich nematic and a sphere rich isotropic phases. Our results show that the excluded volume interactions are capable alone to explain the experimental observation of the nematic-nematic demixing, but they fail for the description of isotropic-isotropic one (Chen et. al., Soft Matter, 11, 5775 (2015)).

description: This work reports the antireflective properties of zinc oxide nanorod arrays implemented on top of
silicon heterojunction solar cells with front contacts based on aluminium doped zinc oxide. This is proposed as a
cheap, abundant and environment-friendly substitution for commonly used indium doped tin oxide. The results show
a reduction in the average weighted cell reflectivity and hence an enhancement in the short circuit density by up to
8,8 % for cells with 300 nm AZO front contact. Zinc oxide nanorods are grown by electrochemical deposition, which
is a low-cost and industrially applicable method, since no vacuum conditions and high temperatures are required.
