Kebijakan Nota Kesepahaman Pengawasan Partisipatif BAWASLU dan JPS Sumatera Barat pada Pemilihan Umum Tahun 2024

The General Election Supervisory Agency (BAWASLU) has several limitations in achieving electoral justice technically, namely personnel limitations and the vast geographical scope of the supervisory area. Then the challenge becomes even more complicated in the simultaneous 2024 elections, which place digital media as the primary space for political campaigns. Also, in the policy of the Memorandum of Understanding for participatory oversight with the West Sumatra Editors' Network (JPS), 10 out of 16 JPS media outlets placed political advertisements on their respective websites or news portals, indicating that the media have political tendencies. The goal of this research is to examine the implementation of the policy and the news coverage it generates. The research method used is quasi-qualitative with a policy analysis framework. Data collection was conducted through observation, interviews, and document studies with key informants from BAWASLU West Sumatra and JPS. In addition, this research is supported by the framing analysis method to see how the news in participatory oversight policies is framed and constructed to encourage active public participation in election oversight. The results of this study show the role of each institution, with BAWASLU West Sumatra playing the role of agenda-setting in news coverage by determining and providing information, while JPS constructs and publishes the news. Then, the results of the framing analysis show that the JPS media predominantly uses event frames (43%) and idea frames (43%), while the low figurative frame (14%) indicates the media's independence from political interests. However, the tone or mood of the news coverage is dominated by a hopeful tone (73.5%) compared to an advisory tone (21.8%), thus tending to build optimism rather than encouraging direct public participation. In general, this news pattern directs JPS more towards the public relations function of BAWASLU rather than the educational function to encourage active public participation in election supervision.

Images of Violence: An Analysis of Visual Frames in U.S. Nightly National Broadcast News Coverage of Black Lives Matter Protests

Demonstrations following the murder of George Floyd culminated into the largest social justice movement in U.S. history. While most of the protests were peaceful, violent imagery was prevalent across local and national broadcast news. Guided by previous research on the protest paradigm, this study examines visual framing methods to understand how broadcast journalists represented the Black Lives Matter movement. The research analyzed 3,627 images from 12 days of coverage across 6 broadcast television news stations. The analysis compares the proportion of visual frames from broadcast news to publicly available data from the Armed Conflict Location and Event Data Project (ACLED). The content analysis found two areas by which American broadcast news’s coverage perpetuated elements of the protest paradigm: coverage portrayed the protests as being more violent than they actually were, and coverage focused on protestor violence. However, the analysis revealed a shift towards focusing on police violence rather than protestor violence at the end of the sample period, indicating a transition away from pitfalls of the protest paradigm. As news media have historically relied on visuals to allow audiences to see for themselves, it is crucial to understand how the 2020 wave of Black Lives Matter protests were visually framed.

Computational Fluid Dynamics Analysis and Validation with Field Test of 1 MW Hydropower Turbine System

This study analyzed and validated a 1 MW hydropower turbine system using computational fluid dynamics (CFD) in conjunction with field test data. The fluid domain of the hydropower system includes the runner blade, vane, duct, and both inflow and outflow free surface flows. An implicit unsteady flow solver and the SST k-ω turbulence model were employed. The rotational motion of the rotor blade was simulated using the moving reference frame (MRF) method. To handle a non-conformal mesh among the intake, runner, and outlet domains, an internal interface boundary condition was applied. System performance was evaluated by adjusting the guide vane opening ratio and the runner blade pitch angle. A free surface model was also developed to accurately represent the water level. The results show that the CFD analysis predicted the turbine’s power output with a maximum deviation of 1.7% from field test measurements under different tide conditions. The numerical analysis also confirmed the influence of the runner blade pitch angle, with a 1° change in pitch angle leading to a 68 kW variation in power output. The accuracy of the CFD analysis was verified by comparing it to performance data from actual field tests.

Strong field-induced three-body fragmentation dynamics of CH3Cl2+

Abstract We investigate the three-body fragmentation of CH3Cl dications induced by intense femtosecond laser pulses in a home-built Recoil Ion Momentum Spectrometer (RIMS) setup. This study focuses on two pathways: (1) H + CH2 + + Cl+, and (2) H+ + CH2 + + Cl. To understand the complex excited-state dynamics of the dication and the momentum sharing between the fragments, Dalitz plots, Newton diagrams, and the native frame method were used, which helped to distinguish between the concerted and sequential fragmentation mechanisms. We further discuss the dissociation pathways theoretically using density functional theory (DFT) calculations. Although the signatures of both concerted and sequential mechanisms were present and overlapping, the concerted mechanism was dominant for both pathways. On positively chirping the pulses, the concerted mechanism remained unaffected, while the sequential mechanism, in some cases, was suppressed. This observation demonstrates that the pulse chirp influences the complex fragmentation dynamics of the CH3Cl dication.

Higher order angular kinematic quantities computed with dual numbers

We present a comprehensive methodology for calculating angular kinematic quantities up to the fourth order using automatic differentiation with dual numbers. Two approaches are employed: the vector method, which uses position vectors and derivatives of three non-collinear points, and the body-fixed frame (BFF) method, which differentiates an attached basis to the rigid body. The BFF method avoids indeterminacy and divergence issues. Numerical examples, drawn from robotics and classical mechanics, validate the methodology and demonstrate its robustness. Our approach effectively addresses challenging inverse problems of acceleration, jerk, and jounce/snap.

Shape Functions Development for Beam-Column Element with Semi-Rigid Connections in Second-Order Steel Frame Analysis

The objective of this paper is to provide a novel method for developing the shape functions of a beam-column element with semi-rigid connection ends, thereby establishing a static analysis method for semi-rigid steel frames. This method takes into account the influence of the P-Delta effect, according to the finite element method based on displacement (FEM). The shape function is established directly from a third-order Hermitian displacement function polynomial combined with the bending element deflection differential equation. The linear elastic stiffness matrix, the geometric stiffness matrix of a semi-rigid connection beam-column, and the equilibrium equation of the element in a local coordinate system are simultaneously obtained by applying Castigliano’s theorem (Part 1) for elastic deformation potential energy expression. The computational program was developed using Matlab software, and the calculation results are verified against published research results, showing that the derived shape functions and the steel frame analysis method are reliable and trustworthy. In addition, this article also derives stiffness matrices and an equivalent nodal load vector for specific cases where the semi-rigid connection is fully rigid (FR) or a pin connection. The derived shape functions are polynomial expressions with coefficients that are simply calculated from the connection stiffness and the geometric and material characteristics of the element, making them highly convenient to use.

Dissecting the Political Persona of the 2024 Indonesian Presidential Election through Visual Framing Analysis

Public interest in political battles is constant, and the Indonesian presidential election in February 2024 is no exception. The three presidential candidates, who have been declared, aggressively establish their political personas and gain exposure and notoriety using Instagram, including @aniesbaswedan, @ganjar_pranowo, and @prabowo. This study aims to dissect the political persona of the 2024 Indonesian presidential candidates using the visual framing analysis method, studying how certain points of view are emphasized or made prominent through visual messages. While other framing studies focus on textual analysis, visual framing analysis is rarely employed even though visual elements have the power to build emotional affection and can last longer in memory. The study's data set comprises Instagram posts from the officially declared presidential contender (@aniesbaswedan from October 3, 2022; @ganjar_pranowo from April 21, 2023; @prabowo from August 12, 2022) to May 21, 2023. The research findings indicate that the political persona built by each presidential candidate still revolves around aspects of their own inherent identity such as religion, race, ethnicity, tribe, customs, habits, education level, economic status, social status, family background, and political stance, rather than providing a clear picture of their priority policy programs when in office.

The problems of environmental quality in Indonesia: Do education levels matter?

Abstract Environmental degradation has emerged as a significant global concern in both emerging and industrialized nations. Immense body of economic literature have verified the probable factors that may become the reasons for environmental degradation and some studies have shown that education is a crucial aspect in restoring the environmental quality. This study aims to understand the impact of different levels of education on environmental quality in Indonesia by Utilizing the Dynamic Ordinary Least Squares (DOLS) regression method for the time frame spanning from 1996 to 2021. The current research employs load capacity factor as a replacement indicator for environmental quality. This study concludes that higher population with basic education level will reduce the environmental quality, while higher population with intermediate education increase the environmental quality. Finally, this study also finds that higher population with advanced education level will harm the environmental quality. Based on the results, it is important for the Government to create compulsory environmental-friendly curricula in all levels of education that supports the reduction of environmental problems in Indonesia.

Performance-based seismic design of low-rise steel moment-resisting frames targeting collapse fragility curve

The aim of this study is to develop a performance-based seismic design method targeting a desirable collapse fragility curve. This direct fragility-based design method is developed and validated for low-rise steel moment-resisting frames. To this end, a relationship is first defined between target fragility curve and design displacement. To this end, 4-story buildings are designed with the design drift ratios of 1.5 % to 4 % and the seismic fragility analysis is performed via the Monte Carlo simulation. The mentioned relationship is derived by plotting the median collapse spectral acceleration versus the design drift ratio. With regard to have this relationship, a modified version of performance-based plastic design method is then proposed. The direct fragility-based design method has been proposed for the low-rise buildings located in Log Angeles. However, its efficiency is also validated for two other regions of Vancouver, Canada and San Francisco, U.S. It can be found from the results that the fragility curve of designed buildings is very close to the target fragility curves. Therefore, the direct fragility-based design method is capable of achieving a target fragility curve and can be considered as an effective design method for low-rise steel moment-resisting frames.

The effect of physiological activation on intuitive decision-making performance in basketball players at various level of athleticism

ABSTRACT This study seeks to explore the effects of physiological activation intensity on basketball intuitive decision-making performance at various levels of athleticism by means of image framing method. A total of 68 subjects were recruited and categorised into an expert group and a novice group. An active intervention on the physiological activation intensity when engaging in intuitive decision-making was performed by means of a visual information stimulus for two groups of subjects. Moreover, the accuracy (ACC) and reaction time (RT) of intuitive decision-making were tested under various conditions of physiological activation intensity and different groups. Analysis of reaction time (RT) as the dependent variable revealed that physiological activation intensity significantly affected RT, which decreased with increasing physiological activation intensity. When analyzing accuracy (ACC) as the dependent variable, a significant interaction effect with the level of athleticism was identified. In the expert group, ACC at high physiological activation intensity was significantly higher than at low physiological activation intensity. Conversely, the novice group showed no significant difference in ACC between high and low physiological activation intensities. Additionally, across both low and high physiological activation intensities, the expert group's ACC was significantly higher than that of the novice group. The intensity of physiological activation has a significant impact on the intuitive decision-making ability of basketball players, and psychological skill training should be integrated into daily training to assist basketball players in better understanding their physiological activation levels.

Observation of sequential three-body dissociation of camphor molecule—a native frame approach

Abstract The three-body dissociation dynamics of the dicationic camphor molecule (C10H16O2+) resulting from Auger decay are investigated using soft x-ray synchrotron radiation. A photoelectron-photoion-photoion coincidence method, a combination of a velocity map imaging spectrometer and a time-of-flight spectrometer is employed to measure the 3D momenta of ions detected in coincidence. The ion mass spectra and the ion–ion coincidence map at photon energies of 287.9 eV (below the C 1s ionization potential) and 292.4 eV (above the C 1s ionization potential for skeletal carbon) reveal that fragmentation depends on the final dicationic state rather than the initial excitation. Using the native frame method, three new fragmentation channels are discussed; (1) CH2CO+ + C7H 11 + + CH3, (2) CH 3 + + C7H 11 + + CH2CO, and (3) C2H 5 + + C6H 9 + + CH2CO. The dominating nature of sequential decay with deferred charge separation is clearly evidenced in all three channels. The results are discussed based on the experimental angular distributions and momenta distributions, corroborated by geometry optimization of the ground, monocationic, and dicationic camphor molecule.

Characterization of myocardial ischemia-reperfusion injury in a pig model with novel CW T1r and RAFF2 MRI methods in 1.5T

Abstract Introduction Myocardial ischemia-reperfusion injury (IRI) occurs after myocardial infarction when reperfusion aggravates the initial damage in myocardium by vast infiltration of inflammatory cells and elevated oxidative stress in myocardium that may lead to cardiac remodeling, heart failure and even death [1]. Magnetic resonance imaging (MRI) can accurately determine the anatomy of the heart and to characterize myocardial tissue. Novel endogenous rotating frame MRI methods, including continuous wave (CW) T1r and relaxation along a fictitious field with rank 2 (RAFF2), have been shown to characterize MI and other CVD in mouse and human myocardium with high sensitivity and specificity [2,3]. CW T1r and RAFF2 contrasts are occurring during radio frequency (RF) pulse (in kHz range) making them to be sensitive to slow molecular motions [2]. Comparing to conventional endogenous T1 and T2 methods, these are occurring after the RF pulse (in Larmor frequency (MHz) range) and therefore, these are non-selectively sensitive to different correlation times [4]. Golden standard to image MI is to use contrast agent (CA) in late gadolinium enhancement (LGE) method [2,4]. Using CA has drawbacks and therefore, there is an urgent need for optimizing the endogenous MRI methods in clinical practice. Purpose To characterize myocardial IRI in a pig model and to determine the sensitivity of both novel and conventional cardiac MRI methods. Methods IRI operation was done in 7 pig (30-35 kg) by occluding the LAD with a balloon catheter for 50 minutes. Imaging was done with 1.5T (MAGNETOM Aera) at 3 days and 28 days after the operation. Pig hearts were imaged with conventional native T1, T2, LGE, and with novel CW T1r and RAFF2 methods in both time points. These were imaged before CA injection and LGE was done 25 minutes after CA injection. Relaxation time mappings were done in a pixel-by-pixel manner with monoexponentially fitting. Region-of-interest (ROI) analysis was done to determine the relaxation times in IRI and remote areas. LGE was used to confirm the IRI areas in the myocardium. Relative relaxation time difference (RRTD)-values were calculated with the function of (((Relaxation Time of IRI area) – (Relaxation Time of Remote Area))/ (Relaxation Time of Remote Area)) to determine the contrast difference between IRI and remote areas. Results Relaxation times were elevated in IRI areas compared to remote areas (Figure 1A). Novel rotating frame RRTD-values were significantly higher than RRTD-values in conventional methods. This means that novel methods have larger contrast difference between IRI and remote areas compared to conventional methods, which indicates that novel methods are sensitive to characterize IRI area (Figure 1B). The location of MI areas was similar in both novel rotating frame and conventional methods compared to LGE (Figure 2). Conclusion Novel rotating frame relaxation time methods are sensitive to characterize the IRI area in pig model.Relaxation times, RRTD-valuesRelaxation times maps and LGE

A least-squares Fourier frame method for nonlocal diffusion models on arbitrary domains

We introduce a least-squares Fourier frame method for solving nonlocal diffusion models with Dirichlet volume constraint on arbitrary domains. The mathematical structure of a frame rather than a basis allows using a discrete least-squares approximation on irregular domains and imposing non-periodic boundary conditions. The method has inherited the one-dimensional integral expression of Fourier symbols of the nonlocal diffusion operator from Fourier spectral methods for any d spatial dimensions. High precision of its solution can be achieved via a direct solver such as pivoted QR decomposition even though the corresponding system is extremely ill-conditioned, due to the redundancy in the frame. The extension of AZ algorithm improves the complexity of solving the rectangular linear system to O(Nlog2⁡N) for 1d problems and O(N2log2⁡N) for 2d problems, compared with O(N3) of the direct solvers, where N is the number of degrees of freedom. We present ample numerical experiments to show the flexibility, fast convergence and asymptotical compatibility of the proposed method.

Development of Double Frame Method to improve the seismic performance of low-rise reinforced concrete buildings

ABSTRACT The current paper proposes a seismic reinforcement method that uses a double frame and is called the Double Frame Method (DFM). Performance tests are conducted to assess the material suitability of a post-installed anchor that directly connects the existing frame to the double frame, while a shear performance test is conducted to examine the vertical connector. The performance of column members with and without DFM reinforcement was compared and evaluated. Ultimately, we have fabricated a two-story, one-span reinforced concrete existing frame test specimen and a DFM reinforced frame test specimen that we can use to examine the effect of improving seismic performance through repeated loading tests. The result of the anchor’s pull-out test show that the average tensile strength is 27.9 kN, exceeding the average design strength of 21.7 kN suggested by the manufacturer. The shear strength test results of the anchor show an average value of 28.7 kN. Meanwhile, the vertical connector test show that the internal force per anchor is 46.83 kN, which is approximately 163% more than the single anchor design shear strength of 28.7 kN. As a result of the DFM-reinforced column test, in the actuator direction, the yield strength is improved by about 120%, while the maximum strength is improved by about 150–180%. As a result of the two-story frame experiment, the double frame reinforced specimen shows a maximum strength of about 4.0 to 4.5 times that of the non-seismic specimen.

Reassessing ayahuasca regulation in Brazil: strategic framing and cumulative gains

Background In the early twentieth century, ayahuasca gained popularity in northern Brazil, causing political tension due to moral hostility. However, over the course of the century, despite the proscription of DMT and the intensification of the ‘War on Drugs’, three phases of cumulative political gains eventually led to the full regulation of ayahuasca, in 2010. How was this achieved? Methods This paper provides a comprehensive reassessment of the existing literature on ayahuasca in Brazil, utilizing social movement theory. Emphasis is placed on framing methods, or how movements strategically present their aims to particular audiences, in order to effect political change. Results First, ayahuasca churches constructed a religious frame that emphasized their Christian pedigree. Second, when harassment intensified, ayahuasca was reframed as a charitable endeavour. Finally, in the transition to democracy, the religions added a scientific frame, collaborating with the state to review scientific evidence and establish policy parameters for regulation. Conclusion Framing ayahuasca as Christian and focusing on charity and science were neither straightforward nor unproblematic, but did allow ayahuasca groups to successfully avoid persecution, establish relationships with powerful actors, and eventually achieve full regulation. This case study provides unique insights into the role of social movements in successful drug policy reform, especially how movements can strategically adapt to and influence prevailing moral codes, resulting in concrete political victories.

Research on a Strategy for Prediction Methods of Submarine Self-Propulsion Hydrodynamic Performance

To investigate the impact of different computational strategies on the self-propulsion hydrodynamic performance of a submarine model, a study was conducted using the RANS method, employing both the steady-state Moving Reference Frame (MRF) method and the unsteady Rigid Body Motion (RBM) method. Numerical simulations of the self-propulsion hydrodynamic performance of the submarine model were performed under different computational strategies, including submarine with propeller, submarine first and propeller second, and propeller rotational speed iteration. The differences between these strategies were analyzed from various perspectives, such as submarine resistance, propeller hydrodynamic performance, total solver actual runtime, propeller unsteady bearing forces, and induced fluctuating pressure. The results indicated that when conducting numerical simulations of the self-propulsion hydrodynamic performance of the submarine with a propeller, the fluctuation ranges of the submarine resistance, propeller thrust, and torque obtained by the steady MRF method were within 0.1% to 0.8%, compared with the three strategies in the unsteady state. In terms of computational efficiency, strategy 3 (RBM—submarine with a propeller) had the lowest computational efficiency, and the time to obtain a self-propulsion curve was 11.9 times, 4.4 times, and 3.1 times that of strategy 1 (MRF + RBM—submarine with a propeller), strategy 2 (RBM—submarine first, then propeller), and strategy 4 (RBM—propeller rotational speed iteration). When analyzing the propeller excitation forces under the submarine’s self-propulsion state using the steady-state MRF method combined with the unsteady RBM method, the frequency domain peak fluctuations were within 5% compared with the three strategies in the unsteady state, making this method suitable for numerical simulations of propeller excitation forces. These findings provide methodological support for evaluating the performance of the submarine’s hydrodynamic propulsion system.

A projection-based time-segmented reduced order model for fluid-structure interactions

In this paper, a type of novel projection-based, time-segmented reduced order model (ROM) is proposed for dynamic fluid-structure interaction (FSI) problems based upon the arbitrary Lagrangian–Eulerian (ALE)-finite element method (FEM) in a monolithic frame, where spatially, each variable is separated from others in terms of their attribution (fluid/structure), category (velocity/pressure) and component (two/three dimension) while temporally, the proper orthogonal decomposition (POD) bases are constructed in some deliberately partitioned time segments tailored through extensive numerical trials. By the combination of spatial and temporal decompositions, the developed ROM approach enables prolonged simulations under prescribed accuracy thresholds. Numerical experiments are carried out to compare numerical performances of the proposed ROM with corresponding full-order model (FOM) by solving a two-dimensional FSI benchmark problem that involves a vibrating elastic beam in the fluid, where the performance of offline ROM on perturbed physical parameters in the online phase is investigated as well. Extensive numerical results demonstrate that the proposed ROM has a comparable accuracy to while much higher efficiency than the FOM. The developed ROM approach is dimension-independent and can be seamlessly extended to solve high dimensional FSI problems.
