An analysis of farm household income in West Java, Indonesia : a study of two villages from the rural dynamic study
Creators: name: Yusuf, Abrar S
Publisher: name: Canberra, ACT : The Australian National University
Year: 1979
Subjects: subject: Farm income Indonesia Java

description: This study is an investigation of the structure of farmers' income in two villages in Java, Indonesia. At the same time an assessment was made of the effect on these farmers' incomes of the government sponsored rice BIMAS programme. Possibilities of increasing farm income were considered given the existing levels of technology, prices and resource available. The data used were from two of six sample villages (a base-line data survey) collected in February 1977 by the Rural Dynamics Study, Agro Economic Survey in the Cimanuk River Basin. The results indicate that on average people in the two sample villages lived above the poverty line, if this is taken as 240 kg milled rice equivalent per capita per year. The income distribution of the sample was less uneven than income distribution in Java because of the contribution of off-farm income. It was also found that low income farmers obtained less benefit from government assistance than high income farmers. With respect to resource use allocation, the results of the analysis have to be treated with caution because of the inadequacy of the data. It was observed that the government programme to assist all farmers should be directed to non-rice crop production as well as to rice production. Because of conceptual problems, data limitations and statistical problems, a firm statement on policy conclusions was not attempted and further study was recommended.

The quality of government conditions political disagreement over redistributive policies

description: This study argues that the quality of government structures the divide of public opinion on redistribution within countries. Countries with higher government quality have both the capacity and impartiality required to implement effective and fair redistribution. In effect, material self-interest and fairness-based evaluations should become better predictors of policy preferences in countries with higher government quality. An empirical analysis of survey data from 40 institutionally diverse countries supports this theory. Interaction regression models show that the government quality moderates the effects of income and unfairness perceptions on redistribution preferences. Both preference drivers are more strongly associated with redistribution support in countries with higher government quality. Preferences thereby become more heterogeneous in higher-quality settings. The results offer micro-level support for the theory that government quality structures politics and policies via the public opinion channel. To the extent that public opinion influences political behavior and policymaking, higher government quality should induce a stronger economic left-right divide over these political phenomena.

description: Twin transformation (TT), which synergistically integrates digital and sustainability transformations, is increasingly acknowledged as essential for the future resilience of organizations. Despite its growing importance, the design and implementation of TT within higher education institutions (HEIs) remain underexplored. In this paper, we address this deficiency by developing a TT framework tailored for HEIs, utilizing employee-driven innovation (EDI) approaches to leverage the collective intelligence of employees and students from a value-adding perspective. Furthermore, we have created an iterative roadmap for the implementation of the TT framework. As a foundation for our work, we utilized qualitative data from a HEI as a case study, which included its existing digital transformation strategy. The findings of this paper provide theoretical contributions to the understanding of TT and an adaptable framework that can assist other HEIs in enhancing stakeholder engagement and fostering EDI initiatives to support their TT.

description: We present a photometric and spectroscopic study of the blue straggler S1082 in the open cluster M67. Our observations confirm the previously reported 1.07 day eclipse light curve and the absence of large radial-velocity variations of the narrow-lined star. However, we find two more spectral components which do vary on the 1.07 day period. We conclude that the system is triple. We fit the light and radial-velocity curves and find that the total mass of the inner binary is more than twice the turnoff mass and that the outer companion to the binary is a blue straggler on its own account. We briefly discuss formation scenarios for this multiple system.

First M87 Event Horizon Telescope Results. I. The Shadow of the Supermassive Black Hole

description: When surrounded by a transparent emission region, black holes are expected to reveal a dark shadow caused by gravitational light bending and photon capture at the event horizon. To image and study this phenomenon, we have assembled the Event Horizon Telescope, a global very long baseline interferometry array observing at a wavelength of 1.3 mm. This allows us to reconstruct event-horizon-scale images of the supermassive black hole candidate in the center of the giant elliptical galaxy M87. We have resolved the central compact radio source as an asymmetric bright emission ring with a diameter of 42+/-3 micro-as, which is circular and encompasses a central depression in brightness with a flux ratio ~10:1. The emission ring is recovered using different calibration and imaging schemes, with its diameter and width remaining stable over four different observations carried out in different days. Overall, the observed image is consistent with expectations for the shadow of a Kerr black hole as predicted by general relativity. The asymmetry in brightness in the ring can be explained in terms of relativistic beaming of the emission from a plasma rotating close to the speed of light around a black hole. We compare our images to an extensive library of ray-traced general-relativistic magnetohydrodynamic simulations of black holes and derive a central mass of M = (6.5+/-0.7) x 10^9 Msun. Our radio-wave observations thus provide powerful evidence for the presence of supermassive black holes in centers of galaxies and as the central engines of active galactic nuclei. They also present a new tool to explore gravity in its most extreme limit and on a mass scale that was so far not accessible.

description: The Event Horizon Telescope (EHT) is a very long baseline interferometry (VLBI) array that comprises millimeter- and submillimeter-wavelength telescopes separated by distances comparable to the diameter of the Earth. At a nominal operating wavelength of ~1.3 mm, EHT angular resolution (lambda/D) is ~25 micro-as, which is sufficient to resolve nearby supermassive black hole candidates on spatial and temporal scales that correspond to their event horizons. With this capability, the EHT scientific goals are to probe general relativistic effects in the strong-field regime and to study accretion and relativistic jet formation near the black hole boundary. In this Letter we describe the system design of the EHT, detail the technology and instrumentation that enable observations, and provide measures of its performance. Meeting the EHT science objectives has required several key developments that have facilitated the robust extension of the VLBI technique to EHT observing wavelengths and the production of instrumentation that can be deployed on a heterogeneous array of existing telescopes and facilities. To meet sensitivity requirements, high-bandwidth digital systems were developed that process data at rates of 64 gigabit/s, exceeding those of currently operating cm-wavelength VLBI arrays by more than an order of magnitude. Associated improvements include the development of phasing systems at array facilities, new receiver installation at several sites, and the deployment of hydrogen maser frequency standards to ensure coherent data capture across the array. These efforts led to the coordination and execution of the first Global EHT observations in 2017 April, and to event-horizon-scale imaging of the supermassive black hole candidate in M87.

Revolutionaries and racists : Australian socialism and the problem of racism, 1887-1917

description: "Workers of the World, Unite.’" was the advice from Marx that his followers in Australia in the period 1887 to 1917 found most difficult to I fc. apply .^operating in a wider labour movement that enthusiastically endorsed the ruling racial ideas of the age, the experience of Australian socialism provides a vivid illustration of the complexities of the interaction between socialist groups and the working class they are seeking to influence. The relationship between ’the party’ and 'the class' involves not simply the question of how socialist groups deal with the problem of ideas in the working class that run counter to the tenets of socialist ideology, but also the extent to which these ’incorrect ideas’ affect the socialist groups themselves. The socialist groups examined include the Australian Socialist League, the Socialist Labor Party, the International Socialists, the Victorian Socialist Party, the Barrier Socialist Propaganda Group, the Socialist Federation of Australasia, the Australian Socialist Party, the Queensland Social Democratic Vanguard, the Broken Hill Social Democratic Club, the Kalgoorlie Social Democratic Association, the Western Australian Socialist Party, and the Social Democratic League of New South Wales. The influence of the Industrial Workers of the World, both the ’Detroit’ and the 'Chicago' factions, is crucial to an understanding of the approach to racism of these socialist groups. The emphasis, therefore, is on the attitudes of socialists outside the Labor Party. However, as essential background, attention is given to the development of working class racism and its political expression in the Labor Party's objective of "The cultivation of an Australian Sentiment based on the maintenance of racial purity" and its fighting platform of "Maintenance of White Australia". This involves discussion of the bases of Australian racism and of theories of racism in general, as an understanding of the role of racism is necessary before it is possible to appreciate the dimensions of the problem that working class racism poses for socialists. A study of Australian socialism between 1887 and 1917 reveals a variety of responses to the problem, ranging from uncritical conformity with racist ideas to critical dissent from any ideas, particularly racism, that would prevent the union of the world's workers. The thesis seeks to explain the reasons for the different reactions of the various socialist groups to the problem of working class racism.

description: We report the detection of the lens cluster of the gravitational lens (GL) system Q0957+561 from a deep observation with the Advanced CCD Imaging Spectrometer on-board the Chandra X-ray Observatory. Intracluster X-ray emission is found to be centered 4.3 +/- 1.3 arcsec east and 3.5(-0.6,+1.3) arcsec north of image B, nearer than previous estimates. Its spectrum can be modeled well with a thermal plasma model consistent with the emission originating from a cluster at a redshift of 0.36. Our best-fit estimates of the cluster temperature of T_e = 2.09(-0.54,+0.83) keV (90 percent confidence) and mass distribution of the cluster are used to derive the convergence parameter kappa, the ratio of the cluster surface mass density to the critical density required for lensing. We estimate the convergence parameter at the location of the lensed images A and B to be kappa_A = 0.22(+0.14,-0.07) and kappa_B = 0.21(+0.12,-0.07), respectively (90 percent confidence levels). The observed cluster center, mass distribution and convergence parameter kappa provide additional constraints to lens models of this system. Our new results break a mass-sheet degeneracy in GL models of this system and provide better constraints of ~ 29 percent (90 percent confidence levels) on the Hubble constant. We also present results from the detection of the most distant X-ray jet (z = 1.41) detected to date. The jet extends approximately 8 arcsec NE of image A and three knots are resolved along the X-ray jet with flux densities decreasing with distance from the core. The observed radio and optical flux densities of the knots are fitted well with a synchrotron model and the X-ray emission is modeled well with inverse Compton scattering of Cosmic Microwave Background photons by synchrotron-emitting electrons in the jet.

description: Effective Field Theory technique is one of the most elegant ways to capture the impact of high scale theory, if any, at some low energy by incorporating higher mass dimensional ($\geq 5$) effective operators ($\mathcal{O}_i$). The low energy EFT is described in terms of only light degrees of freedom which can appear on-shell. An essential task while developing the EFT framework is to compute these $\mathcal{O}_i$'s. Hilbert Series is a novel and mathematically robust method to construct the complete set of gauge invariant independent, effective operators. The HS requires the knowledge of the transformation properties of the light DOF and the covariant derivatives under the internal gauge symmetries and conformal groups. The Hilbert Series method, by its virtue, automatically takes care of the redundancies in the operator set due to the Equations of Motion of fields and Integration by Parts with impeccable accuracy. In this paper, we have adopted this methodology to construct the complete set of independent operators up to dimension-6 in the ``Warsaw"-like basis for two different Beyond Standard Model scenarios -- 2HDM and MLRSM. For both these cases, we have calculated the corrections to the scalar, gauge boson and fermion mass spectra due to the dimension-6 operators. The additional contributions to all the Feynman vertices are computed and their impact on different observables, namely Weak mixing angle, Fermi constant, $ρ$ and oblique parameters. We have further discussed how the magnetic moments of charged leptons and production and decay of the massive BSM particles, e.g., charged scalar and different rare processes are affected in the presence of effective operators. We have also constructed the effective scalar four-point interactions and commented on the possible reinvestigation of the theoretical constraints, e.g., unitarity and vacuum stability within these frameworks.

description: We present the calibration and reduction of Event Horizon Telescope (EHT) 1.3mm radio wavelength observations of the supermassive black hole candidate at the center of the radio galaxy M87 and the quasar 3C 279, taken during the 2017 April 5-11 observing campaign. These global very long baseline interferometric observations include for the first time the highly sensitive Atacama Large Millimeter/submillimeter Array (ALMA); reaching an angular resolution of 25 micro-as, with characteristic sensitivity limits of ~1 mJy on baselines to ALMA and ~10 mJy on other baselines. The observations present challenges for existing data processing tools, arising from the rapid atmospheric phase fluctuations, wide recording bandwidth, and highly heterogeneous array. In response, we developed three independent pipelines for phase calibration and fringe detection, each tailored to the specific needs of the EHT. The final data products include calibrated total intensity amplitude and phase information. They are validated through a series of quality assurance tests that show consistency across pipelines and set limits on baseline systematic errors of 2% in amplitude and 1 degree in phase. The M87 data reveal the presence of two nulls in correlated flux density at ~3.4 and ~8.3 giga-lambda and temporal evolution in closure quantities, indicating intrinsic variability of compact structure on a timescale of days, or several light-crossing times for a few billion solar-mass black hole. These measurements provide the first opportunity to image horizon-scale structure in M87.
Local Circumstellar Magnetic Fields Around Evolved Stars

description: I argue that the presence of magnetic fields around evolved stars, e.g., asymptotic giant branch stars, and in PNe, does not necessarily imply that the magnetic field plays a global dynamical role in shaping the circumstellar envelope. Instead, I favor magnetic fields with small coherence lengths, which result from stellar magnetic spots or from jets blown by an accreting companion. Although the magnetic field does not play a global role in shaping the circumstellar envelope, it may enhance local motion (turbulent) via magnetic tension and reconnection. The locally strong magnetic tension may enforce coherence flow which may favor the masing process.

description: We have analyzed ~600 ks of Rossi X-ray Timing Explorer data of the neutron star low-mass X-ray binary and Z source GX 17+2. A study was performed of the properties of the noise components and quasi-periodic oscillations (QPOs) as a function of the spectral properties, with the main goal to study the relation between the frequencies of the horizontal branch and upper kHz QPOs. It was found that when the upper kHz QPO frequency is below 1030 Hz these frequencies correlate, whereas above 1030 Hz they anti-correlate. GX 17+2 is the first source in which this is observed. We also found that the frequency difference of the high frequency QPOs was not constant and that the quality factors (Q values) of the HBO, its second harmonic, and the kHz QPOs are similar, and vary almost hand in hand by a factor of more than three. Observations of the normal branch oscillations during two type I X-ray bursts showed that their absolute amplitude decreased as the flux from the neutron star became stronger. We discuss these and other findings in terms of models that have been proposed for these phenomena. We also compare the behavior of GX 17+2 and other Z sources with that of black hole sources and consider the possibility that the mass accretion rate might not be driving force behind all spectral and variability changes.

Assessment of the Impact of Technology Integration on Quality of Education in Colleges of Education, Nigeria
Creators: name: Magaji, Sule
Publisher: name: MSI Publishers
Year: 2025
Subjects: Technology Integration, Quality of Education and Quantitative Research Design

description: This study examines the assessment of the impact of technology integration on quality of education in collages of education, Nigeria using a quantitative research design method. Findings from study state that technology integration has significant impact on quality of education in collages of education in Nigeria and this suggest that the coefficient for Technology use (-0.25) indicates that for every one-unit increase in the frequency of technology use in teaching, student engagement decreases by 0.25 units. The coefficient for Comfort level (0.30) suggests that for every one-unit increase in educators' comfort level with technology integration, student engagement increases by 0.30 units. The standard errors for Technology use (0.08) and Comfort level (0.10) represent the variability of the coefficients around the true population values. A lower standard error indicates that the coefficient estimate is more precise. The t-statistic for Technology use (-3.13) tests the significance of the coefficient and indicates that the relationship between Technology use and student engagement is statistically significant (p < 0.01). The t-statistic for Comfort level (3.00) also shows statistical significance, suggesting that the relationship between Comfort level and student engagement is significant (p < 0.01). therefore, the study recommends that government should develop targeted professional development programs to enhance educators' comfort levels with technology integration and promote best practices in utilizing technology tools, implement strategies to address economic disparities and ensure equitable access to technology resources for all educators and foster a culture of diversity and inclusion by valuing educators' diverse backgrounds and perspectives in technology integration efforts.

description: We show that the stationary measure for some random systems of two piecewise affine homeomorphisms of the interval is singular, verifying partially a conjecture by Alsedà and Misiurewicz and contributing to a question of Navas on the absolute continuity of stationary measures, considered in the setup of semigroups of piecewise affine circle homeomorphisms. We focus on the case of resonant boundary derivatives.

First M87 Event Horizon Telescope Results. IV. Imaging the Central Supermassive Black Hole

description: We present the first Event Horizon Telescope (EHT) images of M87, using observations from April 2017 at 1.3 mm wavelength. These images show a prominent ring with a diameter of ~40 micro-as, consistent with the size and shape of the lensed photon orbit encircling the "shadow" of a supermassive black hole. The ring is persistent across four observing nights and shows enhanced brightness in the south. To assess the reliability of these results, we implemented a two-stage imaging procedure. In the first stage, four teams, each blind to the others' work, produced images of M87 using both an established method (CLEAN) and a newer technique (regularized maximum likelihood). This stage allowed us to avoid shared human bias and to assess common features among independent reconstructions. In the second stage, we reconstructed synthetic data from a large survey of imaging parameters and then compared the results with the corresponding ground truth images. This stage allowed us to select parameters objectively to use when reconstructing images of M87. Across all tests in both stages, the ring diameter and asymmetry remained stable, insensitive to the choice of imaging technique. We describe the EHT imaging procedures, the primary image features in M87, and the dependence of these features on imaging assumptions.

description: The method of intertwining with n-dimensional (nD) linear intertwining operator L is used to construct nD isospectral, stationary potentials. It has been proven that differential part of L is a series in Euclidean algebra generators. Integrability conditions of the consistency equations are investigated and the general form of a class of potentials respecting all these conditions have been specified for each n=2,3,4,5. The most general forms of 2D and 3D isospectral potentials are considered in detail and construction of their hierarchies is exhibited. The followed approach provides coordinate systems which make it possible to perform separation of variables and to apply the known methods of supersymmetric quantum mechanics for 1D systems. It has been shown that in choice of coordinates and L there are a number of alternatives increasing with $n$ that enlarge the set of available potentials. Some salient features of higher dimensional extension as well as some applications of the results are presented.

Description:

This paper introduces a set of formulas under the framework of EndDigit Quadratic Patterns, a new approach in number theory that reveals predictable patterns in the squares of natural numbers based on their unit digits. By isolating the last digit and analyzing the sequence of perfect squares, this work derives quadratic expressions that generate square numbers ending in specific digits (1, 4, 9, etc.).

description: HST STIS slitless spectroscopy of LMC PNs is the ideal tool to study their morphology and their ionization structures at once. We present the results from a group of 29 PNs that have been spatially resolved, for the first time, in all the major optical lines. Images in the light of \ha, \nii, and \oiii are presented, together with line intensities, measured from the extracted 1D and 2D spectra. A study on the surface brightness in the different optical lines, the electron densities, the ionized masses, the excitation classes, and the extinction follows, illustrating an ideal consistence with the previous results found by us on LMC PNs. In particular, we find the surface brightness decline with the photometric radius to be the same in most emission lines. We find that asymmetric PNs form a well defined cooling sequence in the excitation -- surface brightness plane, confirming their different origin, and larger progenitor mass.

Dust production scenarios in galaxies at z ~ 6-8.3

description: The mechanism of dust formation in galaxies at high redshift is still unknown. Asymptotic giant branch (AGB) stars and explosions of supernovae (SNe) are possible dust producers, and non-stellar processes may substantially contribute to dust production, for example grain growth in the interstellar medium (ISM). Our aim is to determine the contribution to dust production of AGB stars and SNe in nine galaxies at z ~ 6-8.3, for which observations of dust have been recently attempted. In order to determine the origin of the observed dust we have determined dust yields per AGB star and SN required to explain the total amounts of dust in these galaxies. We find that AGB stars were not able to produce the amounts of dust observed in the galaxies in our sample. In order to explain these dust masses, SNe would have to have maximum efficiency and not destroy the dust which they formed. Therefore, the observed amounts of dust in the galaxies in the early universe were formed either by efficient supernovae or by a non-stellar mechanism, for instance the grain growth in the interstellar medium.

description: We present a study focusing on the nature of compact groups through the study of their elliptical galaxies. We determine velocity dispersions ($σ$) for 18 18 bright elliptical galaxies located in the core of Hickson compact groups and a control sample of 12 bright bona fide ellipticals located in the field or very loose groups. Several tests are carried out to avoid sources of systematic effects in $σ$ measurements. We use these velocity dispersions to compare the position of 11 compact group galaxies in the Fundamental Plane to that of a large and homogeneous sample of elliptical galaxies (Burstein et al. 1987). We find that little or no significant difference exists, as far as the Fundamental Plane is concerned, between ellipticals in compact groups and their counterparts in other environments.

description: Personas are often used in requirements engineering to analyze how people from target groups could use prospective systems or services. Recently, the personas approach also gained some popularity for demonstration and marketing purposes. While the usefulness of personas is uncontested, it is not always clear to which extent the target group is covered and which relevant perspectives are still missing. To address this problem, we present a systematic approach to gain a structured analysis of the personas used in a complex development process. The overall goal of this development is to provide an infrastructure for the management of research data and research software using a containerized approach. We applied the FAIR Ecosystem model with its components and relevant stakeholder groups as a basis of the persona construction, and we illustrate how we used this method to categorize the created personas and to identify blind spots. Not every role is currently defined at all institutions – but if they were, how would they shape research at universities in 2034?
