Manajemen Program Siaran Lokal Aceh TV Dalam Upaya Penyebarluasan Syariat Islam Dan Pelestarian Budaya Lokal
Managing broadcasting management is not easy. Managing the broadcasting business is a difficult and challenging. This research aims to analyze the activity of management and organizational performance ACEH TV television media in an effort to disseminate the Islamic Sharia and Preservation of Local Culture in Aceh. This research is descriptive qualitative. Informants of this research is managing director, program director, executive producer, cameraman / reporter, as well as additional informants Regional Chairman of the Indonesian Broadcasting Commission (KPID) Aceh, Aceh Province Department of Islamic Law, and local media observers. The location of this research is in Banda Aceh, Aceh province. Sampling was done purposively. Data collected through observation, interviews, and documentation. Data were analyzed by analysis of an interactive model of Miles and Huberman. The results showed that the ACEH TV as the medium of television that is broadcasting management ACEH have done according to a local television broadcasting standard. Agenda setting function of mass media performed in the ACEH TV dissemination of Islamic Shariah in Aceh and local culture to influence the people of Aceh to implement Islamic Sharia and also maintain the culture and local wisdom Aceh. It can be seen from all the programs that are aired ACEH TV is a program of local cultural nuances of Islamic law. There are still some shortcomings in running broadcasting broadcasting technology such as lack of equipment that is increasingly sophisticated. The results of image editing is very simple, and some programs presenter still looks stiff when in front of the camera
Determination of weights for calculating the weighted averages of similar experiments.
<p>(A) Example of how correlations between inhibitors and stimuli were calculated. The two colored columns represent the vector of phosphoprotein values obtained under all experimental conditions, sorted in an arbitrary but defined way. In the case of the mTOR inhibitor, data for the IGF-I stimulus is missing; these data are to be predicted. Similarly, in the case of the MEK inhibitor, data for the INFg stimulus is missing. The data in common (dashed box) was used to calculate the Spearman rank correlation coefficient. (B) Graphic representation of the normalized correlation coefficients relating inhibitors (top) and stimuli (bottom). The matrices are asymmetric because correlation coefficients were separately normalized for each inhibitor (stimulus), setting the maximum in a row to 1 (yellow) and the minimum to 0 (black). Other values were based on the correlation coefficient, scaling linearly between the minimum and maximum values in the row.</p
Visualization of the data provided to predictors for the phosphoprotein sub-challenge.
<p>Phosphoprotein levels were been normalized such that values above the median for all values are yellow and those below the median are red. Each column is one of the phosphoproteins, clustered based on similarity in expression. Rows correspond to experiments, sorted in an arbitrary hierarchical manner (cell type, time point, stimulus type, and inhibitor type). The white rows that appear to subdivide the dataset represent the missing data to be predicted.</p
PPARG Binding Landscapes in Macrophages Suggest a Genome-Wide Contribution of PU.1 to Divergent PPARG Binding in Human and Mouse
<div><h3>Background</h3><p>Genome-wide comparisons of transcription factor binding sites in different species can be used to evaluate evolutionary constraints that shape gene regulatory circuits and to understand how the interaction between transcription factors shapes their binding landscapes over evolution.</p> <h3>Results</h3><p>We have compared the PPARG binding landscapes in macrophages to investigate the evolutionary impact on PPARG binding diversity in mouse and humans for this important nuclear receptor. Of note, only 5% of the PPARG binding sites were shared between the two species. In contrast, at the gene level, PPARG target genes conserved between both species constitute more than 30% of the target genes regulated by PPARG ligand in human macrophages. Moreover, the majority of all PPARG binding sites (55â60%) in macrophages show co-occupancy of the lineage-specification factor PU.1 in both species. Exploring the evolutionary dynamics of PPARG binding sites, we observed that PU.1 co-binding to PPARG sites appears to be important for possible PPARG ancestral functions such as lipid metabolism. Thus we speculate that PU.1 may have guided utilization of these species-specific PPARG conserved binding sites in macrophages during evolution.</p> <h3>Conclusions</h3><p>We propose a model in which PU.1 sites may have served as âanchorâ loci for the formation of new and functionally relevant PPARG binding sites throughout evolution. As PU.1 is an essential factor in macrophage biology, such an evolutionary mechanism would allow for the establishment of relevant PPARG regulatory modules in a PU.1-dependent manner and yet permit for nuanced regulatory changes in individual species.</p> </div
