Corporate Governance Mechanism: Impact on performance of Ethiopian commercial banks
Creators: name: Getahun, Kibrysfaw
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2013

description: Numerous studies have looked at the implications of corporate governance mechanism on company performance although the literature is not unanimous in its conclusions. The aim of this research is to analyze the effect of different corporate governance mechanisms , particularly board structure, different regulations, ownership structure and depositors influence, on the performance of nine commercial banks of Ethiopia, covering the period of 2005-2012. The study adopts quantitative method research approach by combining documentary analysis and administrating simple questionnaire. The findings of the study shows that proportion of non- executive from board characteristics variable, CAR and reserve requirement from regulation proxies had negative and significant impact on the performance of Ethiopian commercial banks. On the other hand concentrated ownership, deposit ratio and availability of audit committee had a positive and significant impact on banks performance. However, the impact of the remaining variables like board size, board ownership, and liquidity on bank performance is negligible. The study suggests that the directive which regulates banks to have fully non-executive directors need to be modified. Furthermore, by reducing the type and ratio of reserve and liquidity requirement and by devising different mechanism, like establishing deposit insurance, NBE need to encourage banks to decrease their money holdings without the potential of any earning but with interest expense. In addition to this, there need to have directive which can enforce the disclosure of different relevant information like: share register, financial reports and the rating of each bank by NBE to different stakeholders and NBE need to assure the execution of these directives by different banks

description: Since the traffic conditions change over time, machine learning models that predict traffic flows must be updated continuously and efficiently in smart public transportation. Federated learning (FL) is a distributed machine learning scheme that allows buses to receive model updates without waiting for model training on the cloud. However, FL is vulnerable to poisoning or DDoS attacks since buses travel in public. Some work introduces blockchain to improve reliability, but the additional latency from the consensus process reduces the efficiency of FL. Asynchronous Federated Learning (AFL) is a scheme that reduces the latency of aggregation to improve efficiency, but the learning performance is unstable due to unreasonably weighted local models. To address the above challenges, this paper offers a blockchain-based asynchronous federated learning scheme with a dynamic scaling factor (DBAFL). Specifically, the novel committee-based consensus algorithm for blockchain improves reliability at the lowest possible cost of time. Meanwhile, the devised dynamic scaling factor allows AFL to assign reasonable weights to stale local models. Extensive experiments conducted on heterogeneous devices validate outperformed learning performance, efficiency, and reliability of DBAFL.

description: Deposit mobilization is a fundamental part of banking activity. (Banson, et al, 2012), well- defined that "mobilization of deposit for a bank is as essential as oxygen for human being" and "Deposits are the life blood of banking companies". Hence, deposit mobilization is critical to Banks. The research tried to determine factors that affect deposit mobilization, the associated costs of deposit mobilization in private banks. Therefore, the study adopts mixed approach to gather the data. The primary data is gathered using questionnaire. Sampling method of the primary data is purposive sampling technique. While the secondary sources of data were extracted from annual reports of all private commercial banks of Ethiopia, data from National Bank of Ethiopia (NBE) and from Central Statistical Authority (CSA). Regarding the secondary data, the study used time series data from 2000-2014 for analysis made using Classical linear regression method. The study shows that, Age dependency ratio, Investment and money supply, are the most significant factors of deposit mobilization activity. The other variable such as Per capita income has insignificant power to influence the dependent variable. As a result, the study recommended that, Government should increase investment so as to promote economic growth to mobilize deposits since there exists a positive relationship between Deposit and Investment. And private banks ought to increase number of branches to mobilize more resources

description: The Generative Adversarial Network (GAN) is a powerful and flexible tool that can generate high-fidelity synthesized data by learning. It has seen many applications in simulating events in High Energy Physics (HEP), including simulating detector responses and physics events. However, training GANs is notoriously hard and optimizing their hyperparameters even more so. It normally requires many trial-and-error training attempts to force a stable training and reach a reasonable fidelity. Significant tuning work has to be done to achieve the accuracy required by physics analyses. This work uses the physics-agnostic and high-performance-computer-friendly hyperparameter optimization tool HYPPO to optimize and examine the sensitivities of the hyperparameters of a GAN for two independent HEP datasets. This work provides the first insights into efficiently tuning GANs for Large Hadron Collider data. We show that given proper hyperparameter tuning, we can find GANs that provide high-quality approximations of the desired quantities. We also provide guidelines for how to go about GAN architecture tuning using the analysis tools in HYPPO.

description: The Gemini Planet Imager is a high-contrast near-infrared instrument specifically designed to image exoplanets and circumstellar disks over a narrow field of view. We use science data and AO telemetry taken during the first 1.5 yr of the GPI Exoplanet Survey to quantify the performance of the AO system. In a typical 60 sec H-band exposure, GPI achieves a 5$σ$ raw contrast of 10$^{-4}$ at 0.4"; typical final 5$σ$ contrasts for full 1 hr sequences are more than 10 times better than raw contrasts. We find that contrast is limited by bandwidth wavefront error over much of the PSF. Preliminary exploratory factor analysis can explain 60-70% of the variance in raw contrasts with combinations of seeing and wavefront error metrics. We also examine the effect of higher loop gains on contrast by comparing wavefront error maps reconstructed from AO telemetry to concurrent IFS images. These results point to several ways that GPI performance could be improved in software or hardware.

description: Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a secreted protein and a critical regulator of low-density lipoprotein-cholesterol (LDL-C) through inducing degradation of the LDL receptor (LDLR) within the hepatocyte lysosome. PCSK9 deficiency significantly improves the survival rate of cardiovascular disease (CVDs) patients. Up to now, various PCSK9 inhibition approaches have been tested. However, the currently available PCSK9 inhibitors' widespread use is limited due to their inconvenient method of administration and high cost. On the other hand, inhibiting PCSK9 with nutraceuticals is safe and affordable. The plant-derived compound berberine has shown anti-PCSK9 activity in several studies. Berberine is an isoquinoline quaternary alkaloid of phyto origin. Berberine treatment boosts the hepatic expression of LDLRs, while decreasing the expression and secretion of the LDLR modulator PCSK9. The current review presents a collection of in vitro and in vivo studies investigating berberine's effects on PCSK9 mRNA expression, protein level, and function.

description: The physics potential of measuring $B^0_{(s)}\toπ^0π^0$ and $B^0_{(s)}\toηη$ decays via four-photon final states at Tera-$Z$ phase of CEPC or FCC-ee is investigated in this paper. We propose an electromagnetic calorimeter (ECAL) with both high energy resolution and excellent separation power to efficiently reconstruct $π^0$ and $η$ from hadronic final states with high photon multiplicity. The resulting $B$-meson mass resolution is approximately 30 MeV, allowing 3 $σ$ separation between $B^0$ and $B_s^0$. With the assistance of the $b$-jet tagging, the relative sensitivities to $B^0\toπ^0π^0$, $B^0_s\toπ^0π^0$, $B^0\toηη$, and $B^0_s\toηη$ signal strengths at Tera-$Z$ are projected as 0.45%, 4.5%, 18%, and 0.95%, respectively. Their dependence on various detector performances is also discussed. In addition, $B^0\toπ^0π^0$ and its two isospin-related modes are paid special attention due to their roles in the determination of the CKM angle $α$ ($ϕ_2$). The anticipated precisions of their branching-ratio and $CP$-asymmetry measurements at Tera-$Z$ are evaluated. We show that the measurement of the time-integrated $B^0\toπ^0π^0$ $CP$ asymmetry at Tera-$Z$ is complementary to $B$-factory ones. The precision on $α$ combining $Z$- and $B$-factory results reaches $0.4^\circ$, lower than the systematic uncertainties attached to isospin breaking.

description: We consider the problem of transfer learning in an online setting. Different tasks are presented sequentially and processed by a within-task algorithm. We propose a lifelong learning strategy which refines the underlying data representation used by the within-task algorithm, thereby transferring information from one task to the next. We show that when the within-task algorithm comes with some regret bound, our strategy inherits this good property. Our bounds are in expectation for a general loss function, and uniform for a convex loss. We discuss applications to dictionary learning and finite set of predictors. In the latter case, we improve previous $O(1/\sqrt{m})$ bounds to $O(1/m)$ where $m$ is the per task sample size.

description: Although more additional corpora are now available for Statistical Machine Translation (SMT), only the ones which belong to the same or similar domains with the original corpus can indeed enhance SMT performance directly. Most of the existing adaptation methods focus on sentence selection. In comparison, phrase is a smaller and more fine grained unit for data selection, therefore we propose a straightforward and efficient connecting phrase based adaptation method, which is applied to both bilingual phrase pair and monolingual n-gram adaptation. The proposed method is evaluated on IWSLT/NIST data sets, and the results show that phrase based SMT performance are significantly improved (up to +1.6 in comparison with phrase based SMT baseline system and +0.9 in comparison with existing methods).

The Role of Performance Audit on Performance Improvement and Accountability in the Audited Public Sectors of Oromia National Regional State
Creators: name: Balli, Regassa
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: The main objective of this research project is to assess the role of performance audit on performance improvements and accountability in some of the selected audited public sectors in Oromia National Regional State. The factors used to assess performance improvement were perceptions of the audited public sectors on the performance audit, perceptions of the audited public sectors on the auditors' performance audit recommendations, and improvements that the audited public sectors made by implementing performance audit recommendations. The factors used to assess accountability were activities performed by the legislature or 'caffee' on performance audit findings, and media participation in performance audit report from viewpoint of these selected public sectors on which performance audit were conducted. The study has employed descriptive research method. Survey method has used to conduct this descriptive research. Closed ended questionnaires using Likert 5 scales distributed to these some selected public sectors on which performance audits had conducted from the year 2010 to 2013. The data collected have analyzed using Microsoft excel which is appropriate for this descriptive statistics. For statistical interpretation, mean and standard deviation have used. Based on the data analysis made and results obtained majority of the selected audited public sectors for this research on which performance audit conducted have positive or good perceptions on the performance audit. They also have positive or good perceptions on the auditors' performance audit recommendations given by the performance auditors but improvements that they made in implementing performance audit recommendations were small or slight. The findings also show that activities performed by the legislature or 'caffee' from viewpoint of the audited public sectors were small or slight and the media participation in performance audit report from viewpoint of the selected audited public sectors were average or moderate. The study has concluded that performance audit has not resulted in significant role on performance improvements and on accountability in these selected public sectors on which performance audit has conducted. Audited public sectors should make performance audit recommendations implement and be result in performance improvements in these selected audited public sectors. Activities of the legislature and the media on audit report findings should also be more perform to increase role of performance audit on accountability.

description: The process of thermalization in many-body systems is driven by complex interactions among sub-systems and with the surrounding environment. Here we lay the theoretical foundations for the active control of local thermal states in arbitrary non-reciprocal systems close to their equilibrium state. In particular we describe how to (i) force some part of the system to evolve according to a prescribed law during the relaxation process (i.e. thermal targeting probem), (ii) insulate some elements from the rest of the system or (iii) synchronize their evolution during the relaxation process. We also derive the general conditions a system must fulfill in order that some parts relax toward a minimal temperature with a minimum energetic cost or relax toward a prescribed temperature with a minimum time. Finally, we consider several representative examples in the context of systems exchanging heat radiatively.

description: A hybrid classical-quantum approach for evaluation of multi-dimensional Walsh-Hadamard transforms and its applications to quantum image processing are proposed. In this approach, multidimensional Walsh-Hadamard transforms are obtained using quantum Hadamard gates (along with state-preparation, shifting, scaling and measurement operations). The proposed approach for evaluation of multidimensional Walsh-Hadamard transform has a considerably lower computational complexity (involving $O(N^d)$ operations) in contrast to classical Fast Walsh-Hadamard transform (involving $O(N^d~\log_2 N^d)$ operations), where $d$ and $N$ denote the number of dimensions and degrees of freedom along each dimension. Unlike many other quantum image representation and quantum image processing frameworks, our proposed approach makes efficient use of qubits, where only $\log_2 N $ qubits are sufficient for sequential processing of an image of $ N \times N $ pixels. Selected applications of the proposed approach (for $ d=2 $) are demonstrated via computational examples relevant to basic image filtering and periodic banding noise removal and the results were found to be satisfactory.

description: Kepler-20 is a solar-type star (V = 12.5) hosting a compact system of five transiting planets, all packed within the orbital distance of Mercury in our own Solar System. A transition from rocky to gaseous planets with a planetary transition radius of ~1.6 REarth has recently been proposed by several publications in the literature (Rogers 2015;Weiss & Marcy 2014). Kepler-20b (Rp ~ 1.9 REarth) has a size beyond this transition radius, however previous mass measurements were not sufficiently precise to allow definite conclusions to be drawn regarding its composition. We present new mass measurements of three of the planets in the Kepler-20 system facilitated by 104 radial velocity measurements from the HARPS-N spectrograph and 30 archival Keck/HIRES observations, as well as an updated photometric analysis of the Kepler data and an asteroseismic analysis of the host star (MStar = 0.948+-0.051 Msun and Rstar = 0.964+-0.018 Rsun). Kepler-20b is a 1.868+0.066-0.034 REarth planet in a 3.7 day period with a mass of 9.70+1.41-1.44 MEarth resulting in a mean density of 8.2+1.5-1.3 g/cc indicating a rocky composition with an iron to silicate ratio consistent with that of the Earth. This makes Kepler-20b the most massive planet with a rocky composition found to date. Furthermore, we report the discovery of an additional non-transiting planet with a minimum mass of 19.96+3.08-3.61 MEarth and an orbital period of ~34 days in the gap between Kepler-20f (P ~ 11 days) and Kepler-20d (P ~ 78 days).

description: The Gemini Planet Imager (GPI) is a next-generation high-contrast imager built for the Gemini Observatory. The GPI exoplanet survey (GPIES) consortium is made up of 102 researchers from 28 institutions in North and South America and Europe. In November 2014, we launched a search for young Jovian planets and debris disks. In this paper, we discuss how we have coordinated the work done by this large team to improve the technical and scientific productivity of the campaign, and describe lessons we have learned that could be useful for future instrumentation-based astronomical surveys. The success of GPIES lies mostly on its decentralized structure, clear definition of policies that are signed by each member, and the heavy use of modern tools for communicating, exchanging information, and processing data.

Credit Risk Management System of Ethiopian Commercial Banks (Case of Some public and private Banks)
Creators: name: Mekonnen, Sahlemichael
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2009

description: Banking is a business practice, or profession almost as old as the very existence of man. It has sprouted from the very primitive stone age banking, through the Victorian age to the technology driven Google- age banking, encompassing automotive teller machines (ATMs), credit and debit card, correspondent and internet banking ( Wikipedia, 2008). While financial institutions have found difficulties over the years for a multitude of reasons, the major cause of serious banking problems continues to be directly related to lax credit standards for borrowers and counterparts, poor portfolio risk management, or a lack of attention to changes in economic or other circumstances that can lead to deterioration in the credit standing of bank's counter parties. Now a days credit risk is becoming a vicinity of concern not only to bank's but to all in the business world because the risk of a trading partner not fulfilling his obligations in full on due date can seriously Jeopardize the affairs of the other partner. The goal of Credit Risk Management is to maximize banks risk- adjusted rate of return by maintaining credit risk exposure within acceptable parameters. Banks need to manage the credit risk inherent in the entire portfolio as well as the risk in individual credits or transactions. Banks should also consider the relationships between credit risk and other risks. Effective management of credit risk is a critical component of a comprehensive approach to risk management and essential to the long-term success of any banking organization (Basle committee on banking supervision, 2004) The axle of this study is to have a clearer picture of how Commercial Bank of Ethiopia, Construction & Business Bank, Dashen Bank S.C., Awash International Bank S.C., United Bank S.C. and NIB International Bank S.C manage their credit risks. In this light the study in its first chapter gives background to the study and the second part is a detailed literature review on the origin of banking, credit risk management principles, tools, techniques and assessment models. Data analysis and interpretation of results are dealt in chapter three. Finally based on these, conclusions and recommendations were drawn on the last chapter of the paper

description: A simple procedure to incorporate one-loop quantum electrodynamic (QED) corrections into the generalized (Gatchina) nonlocal shape-consistent relativistic pseudopotential model is described. The pseudopotentials for Lu, Tl, and Ra replacing only inner core shells (with principal quantum numbers $n\le 3$ for the two former elements and $n\le 4$ for the latter one) are derived from the solutions of reference atomic SCF problems with the Dirac-Coulomb-Breit Hamiltonian to which the model Lamb shift operator added. QED contributions to atomic valence excitation energies evaluated at the SCF level are demonstrated to exceed the errors introduced by the pseudopotential approximation itself by an order of magnitude. Pilot applications of the new model to calculations of excitation energies of two-valence-electron atomic systems using the intermediate-Hamiltonian relativistic Fock space coupled cluster method reformulated here for incomplete main model spaces are reported. Implications for high-accuracy molecular excited state calculations are discussed.

description: Instance segmentation of nuclei and glands in the histology images is an important step in computational pathology workflow for cancer diagnosis, treatment planning and survival analysis. With the advent of modern hardware, the recent availability of large-scale quality public datasets and the community organized grand challenges have seen a surge in automated methods focusing on domain specific challenges, which is pivotal for technology advancements and clinical translation. In this survey, 126 papers illustrating the AI based methods for nuclei and glands instance segmentation published in the last five years (2017-2022) are deeply analyzed, the limitations of current approaches and the open challenges are discussed. Moreover, the potential future research direction is presented and the contribution of state-of-the-art methods is summarized. Further, a generalized summary of publicly available datasets and a detailed insights on the grand challenges illustrating the top performing methods specific to each challenge is also provided. Besides, we intended to give the reader current state of existing research and pointers to the future directions in developing methods that can be used in clinical practice enabling improved diagnosis, grading, prognosis, and treatment planning of cancer. To the best of our knowledge, no previous work has reviewed the instance segmentation in histology images focusing towards this direction.

description: Origin of magnetic fields, its structure and effects on dynamical processes in stars to galaxies are not well understood. Lack of a direct probe has hampered its study. The first phase of Square Kilometre Array (SKA-I), will have more than an order of magnitude higher sensitivity than existing radio telescopes. In this contribution, we discuss specific science cases that are of interest to the Indian community concerned with astrophysical turbulence and magnetic fields. The SKA-I will allow observations of a large number of background sources with detectable polarisation and measure their Faraday depths (FDs) through the Milky Way, other galaxies and their circum-galactic medium. This will probe line-of-sight magnetic fields in these objects well and provide field configurations. Detailed comparison of observational data with models which consider various processes giving rise to field amplification and maintenance will then be possible. Such observations will also provide the coherence scale of the fields and measure its random component. Measuring the random component is important to characterise turbulence in the medium. Observations of FDs with redshift will provide important information on magnetic field evolution as a function of redshift. The background sources could also be used to probe magnetic fields and its coherent scale in galaxy clusters and in bridges formed between interacting galaxies. Other than FDs, sensitive observations of synchrotron emission from galaxies will provide complimentary information on their magnetic field strengths in the sky plane. The core shift measurements of AGNs can provide more precise measurements of magnetic field very close (

description: Banking around the clock is no longer a remote possibility. But the banks don't have to keep their branches open 24 hours a day to provide this service. This is one of the biggest advantages of Internet banking. Advances in electronic banking technology have created new ways of handling banking transactions, especially via the online banking channel. In Ethiopia, internet banking is still in its early stages and it is not utilized as a considerable savings tool in operating costs for banks and in improving customer relationships. The intent of this research project is to identify the factors affecting the adoption of Internet banking by customers in Ethiopia. An understanding of how demographic characteristics, social factors, and consumer perceptions and attitudes towards internet banking influence the adoption of internet banking can allow banks to create solutions and plans to attract consumers to their internet banking services, thus enabling them to gain a greater share in the banking market. This study investigates attitudes of retail banking customers in Ethiopia, specifically in Addis Ababa, towards the adoption of internet banking. A research framework based on the diffusion of innovation theory was used to identify factors that would influence the adoption of internet banking. This report has reviewed current literature and opinions about this innovative banking technology. It has also reviewed the factors, including consumer demographic characteristics, consumer perceptions toward internet banking characteristics and social influences that affect consumer adoption of this mode of banking. This study presents both the results of the 400 survey questioners and the analysis of these results, with graphs and figures to determine the extent that the factors studied influence customer adoption of internet banking. The key findings revealed that demographic factors including age, income, education level and occupation have a relationship with the adoption of internet banking. Psychological factors including perceived relative advantage, perceived compatibility, perceived complexity, perceived risk, and perceived cost were found to influence the adoption of internet banking. Social influences including opinions of friends, parents and colleagues were not found to be significant factors to influence the adoption of internet banking in the Ethiopian context. And finally possible recommendations were given so that the banking sector in Ethiopia can exploit the potential advantages of internet banking to remain competitive

description: The viability of quantum communication schemes rely on sending quantum states of light over long distances. However, transmission loss can degrade the signal strength, adding noise. Heralded noiseless amplification of a quantum signal can provide a solution by enabling longer direct transmission distances and by enabling entanglement distillation. The central idea of heralded noiseless amplification---a conditional modification of the probability distribution over photon number of an optical quantum state---is suggestive of a parallel with weak measurement: in a weak measurement, learning partial information about an observable leads to a conditional back-action of a commensurate size. Here we experimentally investigate the application of weak, or variable-strength, measurements to the task of heralded amplification, by using a quantum logic gate to weakly couple a small single-optical-mode quantum state (the signal) to an ancilla photon (the meter). The weak measurement is carried out by choosing the measurement basis of the meter photon and, by conditioning on the meter outcomes, the signal is amplified. We characterise the gain of the amplifier as a function of the measurement strength, and use interferometric methods to show that the operation preserves the coherence of the signal.

description: This paper presents an approach to assess the perfusion of visible human tissue from RGB video files. We propose metrics derived from remote photoplethysmography (rPPG) signals to detect whether a tissue is adequately supplied with blood. The perfusion analysis is done in three different scales, offering a flexible approach for different applications. We perform a plane-orthogonal-to-skin rPPG independently for locally defined regions of interest on each scale. From the extracted signals, we derive the signal-to-noise ratio, magnitude in the frequency domain, heart rate, perfusion index as well as correlation between specific rPPG signals in order to locally assess the perfusion of a specific region of human tissue. We show that locally resolved rPPG has a broad range of applications. As exemplary applications, we present results in intraoperative perfusion analysis and visualization during skin and organ transplantation as well as an application for liveliness assessment for the detection of presentation attacks to authentication systems.

description: We study a three-species cyclic game system where organisms face a contagious disease whose virulence may change by a pathogen mutation. As a responsive defence strategy, organisms' mobility is restricted to reduce disease dissemination in the system. The impact of the collective self-preservation strategy on the disease infection risk is investigated by performing stochastic simulations of the spatial version of the rock-paper-scissors game. Our outcomes show that the mobility control strategy induces plasticity in the spatial patterns with groups of organisms of the same species inhabiting spatial domains whose characteristic length scales depend on the level of dispersal restrictions. The spatial organisation plasticity allows the ecosystems to adapt to minimise the individuals' disease contamination risk if an eventual pathogen alters the disease virulence. We discover that if a pathogen mutation makes the disease more transmissible or less lethal, the organisms benefit more if the mobility is not strongly restricted, thus forming large spatial domains. Conversely, the benefits of protecting against a pathogen causing a less contagious or deadlier disease are maximised if the average size of groups of individuals of the same species is significantly limited, reducing the dimensions of groups of organisms significantly. Our findings may help biologists understand the effects of dispersal control as a conservation strategy in ecosystems affected by epidemic outbreaks.

description: Subgap states are responsible for the low-bias transport features of hybrid superconducting--semiconducting devices. Here, we analyze the local and nonlocal differential conductance of Coulomb-blockaded multiterminal superconducting islands that host subgap states with different spatial structures. The emerging patterns of their transport spectroscopy are used to characterize the possible topological nature of these devices and offer the possibility of controlling their transport properties. We develop a next-to-leading order master equation to describe the multiterminal transport in superconductors with both strong Coulomb interactions and multiple subgap states, coupled with metallic leads. We show that the nonlocal differential conductance characterizes the spatial extension of the subgap states and signals the presence of degenerate bound states with a finite support on different parts of the device. Additionally, it displays sharp sign changes as a function of the induced charge of the superconductor, signaling energy crossings among its lowest excited states.

description: This paper aimed to theorize through critical analysis and layered autoethnography how a large communication network, the oldest in the country, was utterly silenced through the use of extralegal means that defines the current state of Philippine democracy. The two-fold purpose of this study is: to process the author’s personal experiences and professional knowledge of the ABS-CBN case using Philippine Media Under Duterte Administration 17 narratives drawn from a layered autoethnographic account of the events leading to the network’s shutdown, and to contextualize the phenomenon according to traditional Habermasian critical analysis. Using a layered account of autoethnography, the researcher systematically analyzed personal experiences alongside data, abstract analyses, and relevant literature, to develop a holistic and in-depth understanding of the ABS-CBN case, the state of contemporary media, and the sociopolitical phenomenon. The phenomenon observed through this academic exercise is what we can call extralegal or the political subjugation of legal processes and instruments. The phenomenon goes beyond legalities and the exercise of legitimate political power, yet it was the means so effectively used to overturn the truth in the name of organized political revenge and the politics of hate, which leads to division. For now, it seems, in the Philippines, press freedom or democracy are not free, and, as this study found out, ABS-CBN paid the price, an unfortunate casualty
