The Integration of Dakwah in Journalism: Peace Journalism

This article discusses the integration of Islam, particularly da’wa, with peace journalism. It argues that Islamic communication is basically peace journalism. Islamic communication consists of tabligh (information), taghyir (so–cial change), khairu ummah (exemplary community), and akhlaq al-karimah (noble behavior, civil society), the purpo–se of which is to perpetuate conflict sensitivity, constructive conflict, and conflict resolution. Muslim journalists can produce articles about Islam to promote Islamic teachings relevant to universal values, including inclusiveness for humanity values which are inclusive. It is important for Muslims to create a platform for sharing information and religious values that can be discussed by audiences.Keywords: Integration of Dakwah in journalism, peace journalism----------------------------------------------------------------------Artikel ini mengulas integrasi Islam, khusunya dakwah, dengan jurnalistik damai (peace journalism). Penulis perpandangan bahwa pada dasarnya, komunikasi Islam adalah jurnalistik perdamaian (peace journalism). Sebab komunikasi Islam terdiri daripada tabligh, taghyir, khairu ummah dan akhlak al- karimah, yang bertujuan untuk membangun kepekaan sosial, perdamaian, dan resolusi konflik. Pula Peace journalism menggambarkan nilai-nilai universal dan inklusif, seperti keadilan, keamanan, kesela–matan, keharmonian, toleransi, hormat kepada semua manusia sebagaimana diajarkan oleh Islam. Oleh karennya, jurnalis Muslim dapat bekerja di media Islam dan meng–hasilkan karya-karya tulisan tentang nilai-nilai Islam yang inklusif. Hal ini penting bagi umat Islam untuk membuat platform untuk berbagi informasi dan nilai-nilai agama yang dapat didiskusikan.Kata Kunci: integrasi dakwah dalam jurnalistik, jurnalistik dama

One-dimensional microcavity-based optical parametric oscillator: generation of balanced twin beams in strong and weak coupling regime

International audienceWe report on a detailed experimental investigation of interbranch parametric scattering processes in onedimensional semiconductor microcavities. Band dispersion and corresponding far field emission patterns are studied by polarization resolved and power dependence measurements under resonant and non-resonant excitation at normal incidence. We demonstrate the realization of optical parametric oscillation of balanced twin beams which are degenerate in energy and split in momentum space. This achievement is shown for both the strong and the weak coupling regime highlighting the versatility of this peculiar microcavity system

Joint inversion of seismic and electric data applied to 2D media

Methods based on the seismic P-wave, seismic surface wave, and apparent resistivity are commonly used in the solution of several near-surface problems. However, the solution nonuniqueness and the intrinsic limitations of these methods can cause inconsistency in the final results. Dispersion curves of surface waves, P-wave traveltimes, and apparent-resistivity data were jointly inverted to obtain internally consistent and more reliable final model of P- and S-wave velocities and resistivity. A collection of 1D layered models was obtained by a deterministic joint inversion algorithm based on the laterally constrained inversion scheme. The three data sets were jointly inverted imposing the same structure and Poisson’s ratio was introduced as a physical link between P- and S-wave velocities to better constrain the inversion. No physical link was imposed between the resistivity and the seismic velocities. The inversion algorithm was tested on synthetic data and then applied to a field case, where benchmark borehole data were available. The synthetic and field examples provided results in agreement with the true model and the existing geologic information, respectively

Seismic expression of shear zones: Insights from 2-D point-spread-function based convolution modelling

Shear zones are common strain localization structures in the middle and lower crust and play a major role during orogeny, transcurrent movements and rifting alike. Our understanding of crustal deformation depends on our ability to recognize and map shear zones in the subsurface, yet the exact signatures of shear zones in seismic reflection data are not well constrained. To advance our understanding, we simulate how three outcrop examples of shear zones (Holsnøy - Norway, Cap de Creus - Spain, Borborema - Brazil) would look in different types of seismic reflection data using 2-D point-spread-function (PSF)-based convolution modelling, where PSF is the elementary response of diffraction points in seismic imaging. We explore how geological properties (e.g. shear zone size and dip) and imaging effects (e.g. frequency, resolution, illumination) control the seismic signatures of shear zones. Our models show three consistent seismic characteristics of shear zones: (1) multiple, inclined reflections, (2) converging reflections, and (3) cross-cutting reflections that can help interpreters recognize these structures with confidence.publishedVersio

Imaging along-strike variability in fault structure; insights from seismic modelling of the Maghlaq Fault, Malta

Seismic modelling studies of outcrop analogues have proven a powerful method to provide a link between geology as observed at outcrop, and the interpretation of subsurface geology from seismic data. Seismic imaging of fault zones is inherently challenging, as they may be associated with steep dips, narrow zones of heterogeneously deformed rocks, and complex geometries at the limit of seismic resolution. We here investigate how along-strike variations in fault geometry and structural style are imaged in reflection seismic images, based on seismic modelling of well-exposed outcrops of the Maghlaq Fault hosted in the Miocene-Oligocene carbonate rocks in Malta. Using two-dimensional seismic modelling, selected structural cross-sections have been modelled, focusing on variations in fault- and hangingwall bed geometries, and dominant seismic signal frequency. The seismic models show great variability in resolution and, thus, level of resolved geologic detail. The modelled seismic images show that, for all signal frequencies, the fault itself is not imaged, but is manifested by terminations of footwall reflections as well as fault-related strain in the form of drag folding of hangingwall beds, in addition to fault-proximal seismic imaging artefacts. Rotated and ‘drag-folded’ hangingwall beds along the fault produces a high-amplitude fault parallel reflection bundle in the immediate hangingwall of the fault. The illumination issues that dominate in low dominant frequency seismic models are less prevalent in the higher-resolution, higher dominant frequency models. The results of this outcrop-to-seismic study offer insight to the relationship between faults and seismic images, which may improve our ability to accurately interpret faults in the subsurface form reflection seismic data.publishedVersio
