Ethical considerations of disaster research in conflict-affected areas

PurposeDebates on the ethics of disaster and humanitarian studies concern unequal relations in research (among research institutes/researchers/stakeholders); the physical and psychological well-being of research participants and researchers; and the imposition of western methods, frameworks and epistemologies to the study of disasters. This paper focuses on everyday ethics: how they need to be translated throughout the everyday practices of research and how researchers can deal with the ethical dilemmas that inevitably occur.Design/methodology/approachThis paper analyses the process of addressing ethics-related dilemmas from the first author's experiences researching disaster governance in high-intensity conflict settings, in particular drawing from 4 to 6 months of fieldwork in South Sudan and Afghanistan. In addition, ethical issues around remote research are discussed, drawing on the example of research conducted in Yemen. It is based on the personal notes taken by the first author and on the experience of both authors translating guidelines for research in remote and hazardous areas into research practices.FindingsThe paper concerns translating ethics into the everyday practices of research planning, implementation and communication. It argues for the importance of adaptive research processes with space for continuous reflection in order to advance disaster studies based on (1) equitable collaboration; (2) participatory methodologies wherever possible; (3) safety and security for all involved; (4) ethical approaches of remote research and (5) responsible and inclusive research communication and research-uptake. Openness about gaps and limitations of ethical standards, discussions with peers about dilemmas and reporting on these in research outcomes should be embedded in everyday ethics.Originality/valueThe paper contributes to discussions on everyday ethics, where ethics are integral to the epistemologies and everyday practices of research.

Subsurface Sediment Deposits of Tanjung Berikat Coast, Bangka, Determined from GPR Interpretation

Tanjung Berikat Coast in Central Bangka, is a part of the Southeast Asian tin belt. We conducted four Ground-Penetrating Radar (GPR) survey lines and 13 hand auger coring to understand sediment deposition and composition. Two similar units were determined from GPR lines BLG 01–BLG 03: Unit A at the top part, reflected by parallel and continuous reflector configuration, weak–strong electromagnetic wave. Underneath Unit A is Unit B, characterized by subparallel configuration, not continuous–chaotic, weak–medium electromagnetic wave. Unit B is absent in BLG 04. We identify another two units from BLG 04 and BLG 03, Unit C, characterized by subparallel reflector configuration, not continuous– chaotic, weak–strong electromagnetic wave. It exhibits distinctive modulating contact with Unit D. Unit D is characterized by chaotic reflector configuration, relatively stronger electromagnetic wave that might be correlated to the granite intrusion Tanjung Klabat. Sediment deposit is composed of fine–coarse sand, consisting mostly of clastic plutonic and clastic biogenic (coral and mollusk fragments), which increase downward. This indicates marine-fluvial influence, which suggests that sea-level changes strongly influence sedimentation process. Unit A from GPR is correlated to these sediment deposits, the other three units might be correlated to weathering of older insitu deposit.

Active Control of Electromagnetic Attenuation Characteristics of Planar Inductively Coupled Plasma

In this article, an inductively coupled plasma (ICP) source with planar transparent cavity is designed, and the active control of ICP on the attenuation effect of electromagnetic wave is studied. The scattering parameters calculation model of ICP is established based on the COMSOL fluid model combined with Z transform finite-difference time domain (ZT-FDTD) method. A point wave source composed of continuous reflection waves in the plasma is observed through the numerical simulation of the model, and the location of the wave source depends on the spatial distribution of the peak electron density. The effects of different pressure (10 mtorr–1 torr), working gas (Ar and O2), and power (200–600 W) on the electromagnetic scattering characteristics are compared through numerical calculation and experimental measurement. The results show that the attenuation frequency band and amplitude can be actively controlled by changing external factors of ICP, such as gas pressure, working medium gas, and power. With the increase of power, the attenuation peak moves to the high-frequency band. With the increase of pressure, the fluctuation of attenuation curve is enhanced, and the attenuation bandwidth is increased. The O2-ICP is more capable of absorbing wave power of the low band below 6 GHz, while the Ar-ICP is more effective in 6–14 GHz. The research results broaden the active stealth mode of aircraft in complex electromagnetic environment.

Becoming a teacher in higher education: Creating an academic development program to catalyse doctoral students' professionalization

AbstractThis paper focuses on exploring the intellectual basis for establishing an academic development program for international doctoral students in social sciences and humanities in Central Europe so as to cultivate a reflective scholarly approach to teaching early on in their academic career. The program conceptions and practices are embedded in the notion that a scholarly approach to teaching integrates the understanding and demonstration of knowledge about teaching and necessitates a continuous learning process about teaching through reflection and through conducting research on teaching in the various disciplines. In particular, taking on board the domains of teaching knowledge which derived from the kinds of reflections on teaching (cf. Kreber & Cranton, 2000; Mezirow, 1991), instructional, pedagogical and curricular knowledge and continuous reflection at the level of content, process as well as premise, are represented in an integrative manner in our overarching program principles and pedagogical strategies. As we see, professionalization of doctoral students' teaching practice in higher education (cf. Lueddeke, 2003) is particularly important in the context of enhanced faculty mobility and internationalization. Therefore, this paper aims to contribute to the literature and practice on establishing academic development programs, especially in academic environments with low institutional support for teaching and lack of formal requirements for professional development.

Teaching Journal: An Effective Tool for Reflective Practice in Teaching among English Language Teachers

Through teaching journals, teachers can actively conduct true and continuous record, description, reflection, and summary of experiences and teaching behaviors with reflection and research value in their own teaching activities in order to make progress in regard to their teaching skills and classroom presentations. This is an effective way and tool to improve English teachers’ reflective practice in teaching along with their own professional development as well as to promote the role transformation as reflective teachers. Given the widespread concern of the reflective practice in teaching along with the fact that teaching journals are effective in reflective teaching, this paper explores this topic and suggests several implications for teaching via documentation and a case analysis of three samples obtained from an actual teacher’s teaching journal.

Complex stratigraphic relationships between volcanic features and sedimentary deposits in a submarine environment: The northern offshore Holocene Ischia volcanic field (Italy)

The correlation between onshore and offshore of the volcanic features in a complex volcanic field area is a difficult task, however, it is a fundamental step in order to better understand the geological evolution of such a complex area and for an assessment of geologic hazards.Ischia is a well exposed and densely populated volcanic field located in the Campania volcanic province of Italy. In order to improve our understanding of the recent volcanic history of Ischia Island, high-resolution seismic reflection profiles were used to identify volcanic and sedimentary features in the northern offshore.The volcano stratigraphy interpretation permitted us to recognize seismic units with a reflection-free/chaotic facies. These latter units have been associated with volcanic deposits and correlated to the main volcanic units outcropping on the northern coast of Ischia Island. They are limited in extent and interlayered with eight seismic units with continuous reflectors corresponding to clastic sedimentary units that were deposited during inter-eruptive phases. The main result of this work is the documentation of volcanic activity during the Holocene in the area offshore between Castello d'Ischia, Ischia Porto (mainly effusive products) and Punta della Scrofa (mainly shallow lava domes and dykes). The key volcanic units were mapped and 3D geological models were reconstructed. The reconstruction of the stratigraphic framework offshore a volcanic coast provides a pathway to the investigation of the stratigraphic relationships between inter-eruptive sedimentary deposits and volcanic units, and permits the assessment of a wide and continuous chronostratigraphic framework in a complex area. Furthermore, the onshore-offshore correlation of the main Holocene volcanic units allows us to better estimate their areal distribution, a critical factor in the hazard evaluation of a coastal volcanic area. The application of seismic volcano stratigraphy illustrates the remarkable possibilities that the study of submarine volcanic fields offers.

Modelling the Process of Reflection with Pre-Service Student Teachers

The article traces the role of reflection in teacher education and explores the issue of the necessity of creating a system of developing student teachers reflective skills in the process of their university studies. The importance of reflection in linking theoretical knowledge with teaching and learning practices is emphasized. The model of guided reflection employed at the Department of Foreign Philology at H.S. Skovoroda Kharkiv National Pedagogical University is described in detail and examined through different research methods, including qualitative and quantitative analysis of various documents (questionnaires, observation charts, reflective essays etc.) and interviews with participant focus groups. The article presents samples of activities used in pedagogy and methodology classes, and observations of student teachers’ behaviours while performing them. Some information about students’ perception of the model steps is also provided. The collected data prove that student teachers manage to get accustomed to continuous reflection and, thanks to gradual transition from communal reflective activities to pair work and individual assignments as well as constant and sufficient scaffolding, interaction with the ‘knowledgeable other’ feel more confident, are getting aware of the benefits of reflection, and are developing skills of reflective practitioners, which are crucial for their further professional and personal growth.

Poor Sleep Quality in Nurses Working or Having Worked Night Shifts: A Cross-Sectional Study.

Night shifts are part of clinical care. It is unclear whether poor sleep quality of nurses working both consecutive night shifts and day shifts after quitting night shifts is common. In this cross-sectional study, Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality as study outcome. Univariable and multivariable linear and logistic regressions were performed to compare PSQI score and prevalence of poor sleep quality between 512 nurses currently working consecutive night shifts and 174 nurses having worked night shifts in the past. The prevalence of poor sleep quality was 62.11% in nurses working consecutive night shifts and 55.75% in nurses having worked night shifts before. In multivariable regressions with adjustment for potential confounders, compared with nurses working consecutive night shifts, nurses having worked past night shifts reported decreased PSQI score [mean difference: −0.82 (95% CI: −1.27 to −0.38, p < 0.001)] and lower poor sleep quality [odds ratio (OR): 0.49 (95% CI: 0.29 to 0.80, p = 0.005)]. In nurses working consecutive night shifts, a rising curve that plateaued at the end was observed between years of consecutive night shifts and PSQI score, p = 0.004. To explore the change in PSQI score after quitting night shift, we constructed a hypothetical prospective cohort from the cross-sectional data. Here, 98 pairs of nurses with consecutive and past night shifts were matched for the number of night shift years, religion, marital status, living condition, hypertension, and hyperlipidemia. In each pair, a hypothetical change in PSQI score was calculated between the two types of nurses and hypothetical years after quitting night shifts was obtained from the matched nurse with past night shifts. A U-shaped curve between change in PSQI and years after quitting night shifts was observed, p = 0.007. The rising curve and U-shaped curve together formed an S-shaped curve, which mapped the change in sleep quality. These results based on the hypothetical cohort constructed from cross-sectional data suggested the presence of persistent poor sleep quality in night shift nurses. Also, we support early and continuous sleep hygiene education and reflection for an optimal strategy for when to cease working night shifts with regard to sleep-related problems.

35.1: Tabletop three‐dimensional floating autostereoscopic display system with 360‐degree continuous visualization

Background Tabletop 3D display is one of the most challenging and exciting 3D displays. Among different 3D display technologies, the integral photography (IP) based tabletop 3D display is a promising 3D display with full‐color and real‐time rendering. Still, few can offer the in‐situ interaction in multi‐user scenes.Methods In this study, we proposed a novel tabletop 3D floating autostereoscopic display system with 360‐degree continuous visualization according to the optical path and rotation design. As the brightness of the floating image will be changed due to the different angles between light source and AIP, we analyzed the AIP‐based light reflectivity and derived the relation formulas of the reflectivity. We also proposed a depth‐based multiple viewpoint rendering algorithm for real‐time face and gesture tracking to achieve the vertical parallax supplement and model control.Results We verified the continuous visualization and light reflectivity analysis results via simulation experiments. As a result, the brightest setting angle (the angle corresponding to the highest light reflectivity) of AIP was influenced by the AIP reflection unit parameters. The proposed tabletop display realized the aerial display of the 3D model and could provide a continuous 360‐degree observation point of view between different polyhedron faces.Conclusions We proposed a tabletop autostereoscopic 3D display system and analyzed the AIP‐based light reflectivity. The light reflectivity formulas were worthy of reference for designing the AIP 3D or 2D displays. The proposed system could meet the observation of multiple users and offer in‐air interactions.

Genesis and petroleum geological significance of calcareous mudstone in Beier Sag

Beier sag is one of the most oil-rich sags in the south of Hailaer Basin in China. The purpose of the study is to clarify the identification characteristics and geological origin of calcareous mudstone strata in Nantun Formation of Beier sag, so as to provide new ideas for the identification and evaluation of high-quality source rocks, and to provide effective support for efficient exploration of oil and gas in the basin. The comparative analysis of logging curves and seismic reflection characteristics shows that the calcareous mudstone layer has the “three high and one low” logging response with high GR (Natural Gamma Ray), high LLD (Deep Investigate Induction Log), high AC (Acoustic) and low DEN (Rock Density), showing continuous and strong seismic reflection characteristics. Through the comparative analysis of experimental data of rock thin slice and microscopic image and organic geochemistry, the layer lithology is mainly gray-black mudstone, locally mixed with oil shale and marl, rich in calcium and algae. The layer has the high abundance of organic matter, good organic matter type ( II1-I ), high hydrocarbon-generating potential and high hydrocarbon-exhausting efficiency. It is the highest quality source rock found in Beier sag, and is the material base to form the large scale oil and gas accumulation. The formation of calcareous mudstone formed in the brackish water and wide lake basin by a wide range, represents the anoxic event early in Cretaceous period and is the significant stratigraphic correlation marker bed of the sag. In addition, this layer and the fan-delta front sand widely distributed in the lower part of Nantun Formation form the most favorable reservoir combination, which controls the plane distribution of oil and gas reservoirs. Above and below the calcareous mudstone strata, oil and gas are very rich.

An Analysis of the Critical Essence of Marx’s Dialectics

Through continuous inquiry and reflection on the roots of religion, Marx was able to understand the limits of political emancipation when the relationship between political emancipation and religion was correctly revealed. People were not only restricted by the metaphysics of ideas but in reality, they were also restricted by capital. Hegel used concepts while Feuerbach used sensibility as ways to rescue them, yet they were all still trapped in metaphysics. Marx proposed a way on the basis of sublating the two, not only in terms of metaphysics but also the capital by thoroughly criticizing reality. It is through the path of dialectics that Marx was able to introduce a higher-level communist society in the internal criticism and denial of capitalist society by profoundly revealing the theoretical dilemma and internal contradictions of the fusion of metaphysics and capital in the pursuit and realization of human freedom and liberation.

The Late Quaternary geological history of the lower Sydney estuary (Australia)

Sydney estuary is a dendritic, drowned river valley on the mid-east coast of Australia and comprises an upper and central section of narrow, sinusoidal channels and embayments and a wide, more marine lower estuary. The current work considered only the lower estuary.Minimal research has been undertaken into the structure of the lower Sydney estuary and previous attempts to integrate geologic and geophysical information are limited. The current study combines previously uninterpreted seismic records and poorly-accessible borehole data into a Late Quaternary history of the lower estuary.High-resolution, continuous reflection seismic (212-line km) interpretation matched borehole-based stratigraphy reasonably well. A bedrock paleo-valley deepened from approximately 40 m below present sea level (bpsl) at the Sydney Harbour Bridge (SHB) to > 90 m bpsl at the estuary mouth. Stratigraphy was dominated by two estuarine sequences, which, in the lower part of the estuary comprised mainly fine-grained, organic-rich sediments with peat, that manifest as multiple, strong dark and light-reflectors on seismic. At the SHB, the upper estuarine sequence developed into a transgressive marine to tidal delta deposit. A thin veneer (up to 10 m) of Modern estuarine sands mantled most of the lower estuary. The elevation of the estuarine sediments at approximately present-day levels and at 20 to 30 m bpsl respectively, strongly indicated deposition during periods of high-level marine transgression, i.e. the Last Interglacial (Marine Isotope Stage, MIS 5.5) event at 130 kyPB to 115 kyBP and the Penultimate Interstadial event (MIS 5.1 at 110–80 kyBP), respectively.Late Pleistocene aeolian sands contributed sediment in the south of the estuary, and remobilisation may have dispersed these sediments more widely. Present-day bathymetric features frequently reflected subsurface erosional structures due to starvation of bedload sediment.

Seismic Reflection Images of Possible Mantle-Fluid Conduits and Basal Erosion in the 2011 Tohoku Earthquake Rupture Area

Multi-channel seismic reflection and sub-bottom profiling data reveal landward-dipping normal faults as potential conduits for mantle-derived fluids in the coseismic slip area of the 2011 Tohoku earthquake (Mw9.0). Normal faults below the helium isotope anomaly sites appear to develop through the forearc crust (i.e., the seafloor sedimentary section and Cretaceous basement) and to evolve to lower dip angles as extension progresses deeper, potentially extending down to the mantle wedge, despite their intermittently continuous reflections. The faults are characterized by high-amplitude, reverse-polarity reflections within the Cretaceous basement. Moreover, deep extension of the faults connecting to a low-velocity region spreading from the Cretaceous basement into the mantle wedge across the forearc Moho suggests that the faults are overpressured by local filling with mantle-derived fluids. The locations of the normal faults are roughly consistent with aftershocks of the 2011 Tohoku earthquake, which show normal-faulting focal mechanisms. The 2011 Tohoku mainshock and subsequent aftershocks can lead the pre-existing normal faults to be reactive and more permeable so that locally trapped mantle fluids can migrate up to the seafloor through fault fracture zones. The reactivated normal faults may be an indicator of shallow coseismic slip to the trench. Locally elevated fluid pressures can decrease the effective normal stress for the fault plane, facilitating easier slip along the fault and local tsunami. The landward-dipping normal faults developing from the seafloor down into the Cretaceous basement are predominant in the middle slope region of the forearc. A possible shear zone with high-amplitude, reverse-polarity reflections above the plate interface, which is almost localized to the middle slope region, suggests more intense basal erosion of the overlying plate in that region.

A reflective process to explore identity in an emerging wine territory: the example of British Columbia

PurposeIdentity is often used in wine territory narratives but its meaning is rarely explored with industry actors. This paper aims to present the development and application of a four-step iterative process for engaging an industry in a complex and deep reflection about its shared identity: understanding identity; identifying commonalities and differences; developing a shared narrative and sharing best practice.Design/methodology/approachThe authors have engaged with over 50 wineries between 2016 and 2018 on the identity of the British Columbia wine territory through workshops, interviews and other conversations. Complementary methods include documentary review and observations.FindingsThe work shows the applicability of the four-step process. Success depends on building relationships with and across the industry; creating independent, safe learning environments and facilitation by an independent party; allowing for feedback between the steps, continuous reflection and reiteration of steps and making the time for complexity.Practical implicationsThe application of the process in British Columbia shows that success depends on building relationships with and across the industry; creating independent, safe learning environments and making the time for complexity.Originality/valueThe paper presents the application of a unique process for industry to explore the identity of a wine territory. It focuses on British Columbia, about which little has been written. Through the process, the industry can better understand identity, what it is, why it matters and how it impacts businesses. The paper’s insights can inspire researchers and industries in their thinking and practice about identity.

Sedimentary processes of shallow-marine turbidite fans: An example from the Huangliu Formation in the Yinggehai Basin, South China Sea

The shallow-marine turbidite fans in the Upper Miocene Huangliu Formation of the Yinggehai Basin in the northwestern South China Sea (SCS) provide an excellent opportunity to understand their sedimentary processes in a shelf depositional environment. The down-slope gravity flow processes and along-slope bottom-current reworking processes of shallow-marine turbidite fans were interpreted by using seismic, well logging, core, petrographic, geochemical, and petrophysical data. Several depositional elements were identified in the shallow-marine turbidite fans, namely, channel-fill high-density turbidites (HDTs), channel-fill low-density turbidites (LDTs) and associated frontal splays, sand-rich/mud-rich lobe deposits, and bottom-current reworked channel-fill/lobe deposits. Deep U-shaped (or V-shaped) seismic reflections and low root-mean-square (RMS) amplitudes characterize the channel-fill HDTs that consist of massive fine-grained sandstones with mud clasts. The channel-fill LDTs, characterized by V-shaped or worm-shaped reflections, mostly consist of normally graded, laminated and rippled, very fine-grained sandstones. Frontal splays are generally associated with channel-fill LDTs. The sand-rich lobe deposits show continuous high-amplitude sheet-like reflections and consist of HDTs and LDTs, whereas the mud-rich lobe deposits show continuous moderate-amplitude reflections and consist of muddy debrites. The bottom-current reworked sandstones (BCRSs), which comprise well-sorted, fine-grained sandstones with traction-current structures, are usually located in the upper parts of thick sandbodies. The variability of depositional elements from large-scale channel-fill HDTs with strong basal erosion in fan-1 to small-scale channel-fill LDTs in fan-2 is closely linked with sea-level fluctuations that result in variable gravity-flow energy and sediment input. However, the reoccurrence of large-scale channel-fill HDTs in fan-3 at sea-level highstands may possibly be attributed to enhanced sediment input from the source areas. Down-slope flow transformation from turbidity flows into muddy debris flows within an individual channel-lobe complex (CLC) resulted in a dramatic increase in clay content and resultant decreasing reservoir quality from the channel-fill HDTs to the mud-rich lobe deposits, because muddy sediments are incorporated into the precursor turbidity flows and turbulence is suppressed. Additionally, it is suggested that the widely developed traction-current structures and tidal signatures (double mud layers, mud-draped ripples, discrete wavy bedding, internal truncation surface, and convex-up laminae) are the products of reworking by internal waves and -tides. During periods of sea-level highstands, the upper parts of gravity-flow sandstones would undergo bottom-current reworking, thus resulting in the retransportation of muddy fines and the formation of reworked sandstones with traction-current structures and tidal signatures. In this study, a combination of traction-current structures, tidal signatures, vertical sequences showing sharp upper contacts and non-gradational upper contacts, and trace elements is considered to be convincing diagnostic criteria in distinguishing reworked sandstones from gravity-flow sandstones. The representative bottom-current reworked sandstones should be preferable hydrocarbon targets in further exploration because of their better reservoir properties compared with gravity-flow sandstones. This research offers some insight into gravity-flow processes and bottom-current reworking processes in a shallow marine environment.

Una isla llamada serendipia: definiciones ético pedagógicas en el proyecto filosofar con niñxs.

This text proposes some lines of reflection and action related to a project that links philosophy and childhood, whose pedagogical and investigative activity has been developed in the province of Córdoba, Argentina, for more than twenty-five years. To do this we recover an experience of workshops with children and adults, in a continuous process of reflection on childhood and how children think about themselves. That experience focuses on imagining a particular space and time – living together on an island where adults cannot be found--and from there question the forms of decision making and participation – of political action – that children perform in the territories they inhabit. Here it is proposed that the circumstance of incompleteness regarding issues such as politics and sexuality encompass all age situations and, therefore, it is more appropriate to let ourselves be traversed by restlessness and doubt than to accept a preconceived world in which problems quickly find answers, and what you do not know or cannot be located in a fixed category is unknown, ignored, or remains hidden. We propose to start by not postulating any pre-conceived notions regarding childhoods--thinking of them as hypotheses with unexplored names, bodies and thoughts to get to know. Likewise, it is assumed that reflection on teaching practice relocates philosophy teachers as intellectuals who keep universal explanations in their “professorial pockets,” and reinvent themselves by dealing with specific problems, the small discoveries one makes through exchanges with others--those others that, as in the case of children, there is much to learn about and from. This is the ethical and political task that emerges from a continuous reflection on shared action. Welcome, then, to the island where everything is to be decided and participated in, the island of Serendipity.

Overcoming constraints of scaling: Critical and empirical perspectives on agricultural innovation scaling.

Scaling is a ubiquitous concept in agricultural research in the global south as donors require their research grantees to prove that their results can be scaled to impact upon the livelihoods of a large number of beneficiaries. Recent studies on scaling have brought critical perspectives to the rather technocratic tendencies in the agricultural innovations scaling literature. Drawing on theoretical debates on spatial strategies and practical experience of agricultural innovation scaling in Ethiopia, this paper adds to the current debate on what constitutes scaling and how to overcome critical scaling constraints. The data for the paper came from a qualitative assessment using focus group discussions, key informant interviews, and document analysis on scaling work done in Ethiopia by a USAID-funded research for development project. The paper concludes with four broad lessons for the current understating of agricultural innovation scaling. First, scaling of agricultural innovations requires a balanced focus on technical requirements and associated social dynamics surrounding scaling targets, actors involved and their social relations. Second, appreciating the social dynamics of scaling emphasizes the fact that scaling is more complex than a linear rolling out of innovations towards diffusion. Third, scaling may not be strictly planned; instead, it might be an extension of the innovation generation process that relies heavily on both new and long-term relationships with key partners, trust, and continuous reflection and learning. Fourth, the overall implication of the above three conclusions is that scaling strategies need to be flexible, stepwise, and reflective. Despite the promises of flourishing scaling frameworks, scaling strategies it would appear from the Africa RISING experience that, if real impact is to be achieved, approaches will be required to be flexible enough to manage the social, processual and emergent nature of the practice of scaling.

Anisotropic diffusion filtering based on fault confidence measure and stratigraphic coherence coefficients

ABSTRACTWe develop an algorithm for seismic data filtering to preserve the boundary information of faults and other geological bodies while suppressing the noise. Based on the theory of anisotropic diffusion filtering, this method explores the relationship between eigenvalues of the structure tensor and local structural features of three‐dimensional seismic images and innovatively introduces the definition of stratigraphic coherence coefficients. Then we propose a new system to design the eigenvalues of the diffusion tensor by using the fault confidence measure and stratigraphic coherence coefficients, which can control the filtering intensity of seismic data in different orientations. The value of fault confidence measure is close to 0 where there are flat continuous reflectors and the intensity of diffusion is strong. On the contrary, the diffusion is very weak within presumptive fault zones. Results of both synthetic model and real data prove that the proposed method can effectively suppress noise, preserve faults well and enhance the continuity of the reflectors, which can provide basic data with high signal‐to‐noise ratio for subsequent seismic interpretation.

The Impact of Continual Reflection Students as Partners: Becoming a/r/tographers

Abstract: In this reflective essay we chronicle working together from fall 2017 through spring of 2020 to discover what Rita Irwin (2013) delineated as “becoming a/r/tography” (p. 198). Our goals are to delineate how undergraduate research as a high impact practice effected the experience of an undergraduate art and design major as she matriculated through the “sticky curriculum” (Orr &amp; Shreeve, 2018, p. 5), and how a/r/tography as a research methodology influenced our collaborative creativity research projects during this three-year period.
