Konvergensi Jurnalistik Tabloid Metrolima Depok di Era Pandemi Covid-19

The MetroLima tabloid has converged by combining two media from print media with internet-based technology, thus creating a new identity, namely MetroLima.Com and MetroLima TV, as well as YouTube and Instagram channels. This step was taken to face business competition and the demands of the times which are all technology-based and of course will adapt to the digital industry. The purpose of this research is to find out how the convergence in the MetroLima Tabloid maintains print media in the current digital era by using technogenic practices in the media amid the Covid-19 pandemic, and how journalistic convergence is applied to the MetroLima tabloid. This study uses a qualitative approach method. Data collection techniques by observation and interviews as well as documentation, the selected informants are editor-in-chief and readers. The results of the study show the newsrom 3.0 convergence model where the news gathering process and content are carried out by one journalist and then to be distributed to all MetroLima Depok tabloid platforms, MetroLimaNews and MetroLima TV as well as MetroLima Depok tabloid social media. The newsroom model is to streamline human resources and summarize work mechanisms. MetroLima tabloid performs convergence using E Grant's theory which refers to 3 dimensions of convergence.

Robert E. Grant's later views on organic development: the Swiney lectures on “Palaeozoology”, 1853–1857

SUMMARY R. E. Grant's advocacy of transmutation is considered in relation to the scientific climate of the 1850s. To understand the palaeontological framework of his development theory, the unpublished “Palaeozoology” lectures, delivered in 1853–7, are analysed and his sources tabulated. The lectures are shown to contain the following additional themes: (1) a refutation of Lyell's steady-state geology, (2) support for serial development, (3) use of metamorphic effacement to explain the lack of pre-Silurian fossils, and (4) nebular hypothesis. The difficulty of supporting serial development using fossil evidence at this late date is discussed, and this difficulty is deemed to have contributed to the failure of Grant's theory of species “generation”.

Effect of temperature on transition probability for a single spin cross-relaxation

Grant's theory of an energy conserving single spin flip in a paramagnetic substance is extended to include the effect of thermal interaction of the spin system with lattice in terms of an appropriate spatial ensemble average. An explicit evaluation of the function φ(ρ) encountered in Grant's theory is presented and shown to lead to a Lorentzian line centered at a temperature dependent frequency.

CROSS RELAXATION BETWEEN CR3+ IONS IN DILUTE POTASSIUM CHROMICYANIDE

Cross relaxation between the 1/2 ↔ −1/2 paramagnetic resonance lines of the two nonequivalent complexes in dilute potassium chromicyanide has been studied, using a technique of cross saturation. The observed dependence of the cross-relaxation rate on frequency and concentration is in good agreement with Grant's theory of cross relaxation. The cross-relaxation rate between spins occupying nonequivalent sites is strongly affected by exchange coupling between nearest neighbors and the large gap between the nearest-neighbor and next-nearest-neighbor sites.
