Makna Ragi dalam Ajaran Tuhan Yesus Tentang Kewaspadaan

Ajaran Tuhan Yesus ada yang berbentuk kalimat lugas dan ada yang kiasan. Penggunaan kata “ragi” dalam beberapa kalimat yang disampaikan Tuhan Yesus tentang kewaspadaan adalah dalam makna kiasan. Itu sebabnya perlu dicari makna kata tersebut sesuai prinsip-prinsip eksegesis.Metode eksegesis yang digunakan meliputi penetapan teks Alkitab yang akan dieksegesis, yaitu Matius 16:6, analisis struktur kalimat dan menyusun terjemahan, analisis konteks penggunaan ragi pada masa itu, penggalian pokok-pokok teologis berdasarkan arti kata dan susunan kata dalam kalimat, dan penerapan eksegesis kepada konteks masa kini.Kesimpulan dari penelitian ini adalah, Yesus menggunakan istilah ragi karena ragi adalah sesuatu yang umum digunakan dalam masyarakat, sehingga arti simboliknya dengan mudah ditarik berdasarkan apa yang dipahami oleh masyarakat. Ragi menggambarkan ajaran, dan ada kesamaan karakteristik ragi dan karakteristik ajaran; pembusukan yang disebabkan oleh sejumlah kecil ragi tidak nampak prosesnya namun nyata Perubahannya, demikian pula cukup sedikit ajaran yang tidak sehat yang dibiarkan mengkontaminasi memiliki potensi untuk merusak seluruh karakter seseorang. Ajaran yang harus diwaspadai adalah pengutamaan terhadap hal-hal yang lahiriah lebih daripada yang rohani, termasuk di dalamnya keangkuhan, kemunafikan, dan pandangan duniawi

The dynamics of loop formation in a semiflexible polymer

The dynamics of loop formation by linear polymer chains has been a topic of several theoretical/experimental studies. Formation of loops and their opening are key processes in many important biological processes. Loop formation in flexible chains has been extensively studied by many groups. However, in the more realistic case of semiflexible polymers, not much results are available. In a recent study (K. P. Santo and K. L. Sebastian, Phys. Rev. E, \textbf{73}, 031293 (2006)), we investigated opening dynamics of semiflexible loops in the short chain limit and presented results for opening rates as a function of the length of the chain. We presented an approximate model for a semiflexible polymer in the rod limit, based on a semiclassical expansion of the bending energy of the chain. The model provided an easy way to describe the dynamics. In this paper, using this model, we investigate the reverse process, i.e., the loop formation dynamics of a semiflexible polymer chain by describing the process as a diffusion-controlled reaction. We perform a detailed multidimensional analysis of the problem and calculate closing times for a semiflexible chain which leads to results that are physically expected. Such a multidimensional analysis leading to these results does not seem to exist in the literature so far.Comment: 37 pages 4 figure

Diffusion of scientific credits and the ranking of scientists

Recently, the abundance of digital data enabled the implementation of graph based ranking algorithms that provide system level analysis for ranking publications and authors. Here we take advantage of the entire Physical Review publication archive (1893-2006) to construct authors' networks where weighted edges, as measured from opportunely normalized citation counts, define a proxy for the mechanism of scientific credit transfer. On this network we define a ranking method based on a diffusion algorithm that mimics the spreading of scientific credits on the network. We compare the results obtained with our algorithm with those obtained by local measures such as the citation count and provide a statistical analysis of the assignment of major career awards in the area of Physics. A web site where the algorithm is made available to perform customized rank analysis can be found at the address http://www.physauthorsrank.orgComment: Revised version. 11 pages, 10 figures, 1 table. The portal to compute the rankings of scientists is at http://www.physauthorsrank.or

Speckle noise reduction in medical ultrasound RF raw images

Ultrasonography is the commonly used imaging modality for the examination of several pathologies due to its non-invasiveness, affordability and easiness of use. However, ultrasound images are degraded by an intrinsic artifact called 'speckle', which is the result of the constructive and destructive coherent summation of ultrasound echoes. This paper aims to generate B-mode images out of radiofrequency (RF) data following standard procedures, a series of steps such as envelope detection, log-compression and scan conversion. The best set of parameters of this pipeline will be selected in order to achieve B-mode images with high quality.info:eu-repo/semantics/publishedVersio

Percolation Effects in Very High Energy Cosmic Rays

Most QCD models of high energy collisions predict that the inelasticity $K$ is an increasing function of the energy. We argue that, due to percolation of strings, this behaviour will change and, at $\sqrt{s} \simeq 10^4$ GeV, the inelasticity will start to decrease with the energy. This has straightforward consequences in high energy cosmic ray physics: 1) the relative depth of the shower maximum $\bar{X}$ grows faster with energy above the knee; 2) the energy measurements of ground array experiments at GZK energies could be overestimated.Comment: Correction of equation (19) and figures 3 and 4. 4 pages, 4 figure

How the mere desire for certainty can lead to a preference for men in authority (particularly among political liberals)

Women are harmed by stereotypes about their fit for positions of authority and changing these stereotypes is not a simple task. As stereotypes have strong epistemic properties, individuals with a high need for cognitive closure (NCC; i.e., the desire for epistemic certainty) can be more likely to accept these stereotypes and, consequently, to prefer men in positions of authority. Consistent with the reactive liberal hypothesis, this effect could be actually more visible among individuals with both a high NCC and left-wing political orientations. We supported these hypotheses in a series of three studies. In Study 1 (N = 217), we found that manipulated NCC predicted preference for men in authority through stereotypes of women as not being fit for authority in a measurement-of-mediation design. In Study 2 (N = 151), we supported this effect in a mediation-as-process design. In Study 3 (N = 391), we found the indirect NCC effect on preference for men in authority was more visible among political liberals. A major implication of this work is that ways of changing the effect of these stereotypes should take into account the NCC, but particularly among individuals with left-wing beliefs
