Economic aspects of livestock production in Punjab, Pakistan
Creators: name: Rauf, Abdul
Publisher: name: Canberra, ACT : The Australian National University
Year: 1982
Subjects: subject: Animal industry Pakistan Punjab

description: The study on the structure of livestock production in Punjab province of Pakistan aims to determine whether the landless participate equally with farm families in livestock production. The impact of mechanisation and land development policies upon animal stocking rate is also investigated. In addition to the above district level analysis, a comparison of livestock production is made between two selected regions with differing production systems to explore the investment priorities. Allocation of resources in livestock enterprises is investigated to identify the resource constraints within regions. Regression analysis of district level cross-sectional data is used to analyse the structure of livestock production in Punjab. A production function approach is applied to estimate the productivity parameters. Alternative livestock production systems are compared in mechanised milkshed versus traditional remote regions. The study concludes that the landless participate equally with farm families in animal enterprise although excluding draft animals. Similar results are shown in three animal categories, viz. milch, young bovines and sheep and goats. Land development policies tend to reduce the livestock population with the exception of milch animal category which is unaffected. In contrast, mechanisation shows a strong complementary relationship with milch animals. Thus, mechanisation appears to be associated with a substantial increase in milk production. The results imply that the ownership of animals is more evenly distributed than the ownership of land in rural Punjab. Hence a rural development strategy based on 'animals' would be more likely to encourage the involvement and participation of the landless and/or marginal farmers who are relatively neglected in crop research and extension programmes. Integration of milk development programmes with the government's mechanisation and land development policies should, therefore, be of higher priority than at present due to strong complementarities among the policies. Research, extension, credit and price policies are suggested to encourage the implementation of the above proposed integrated rural development strategy. These policy proposals are based on the results from the comparison of alternative livestock production systems in the respective regions.

description: We analyse charge inversion in colloidal systems at zero temperature using stability concepts, and connect this to the classical Thomson problem of arranging electrons on sphere. We show that for a finite microion charge, the globally stable, lowest energy state of the complex formed by the colloid and the oppositely charged microions is always overcharged. This effect disappears in the continuous limit. Additionally, a layer of at least twice as many microions as required for charge neutrality is always locally stable. In an applied external electric field the stability of the microion cloud is reduced. Finally, this approach is applied to a system of two colloids at low but finite temperature.

A study of increasing production of basic food crops in Indonesia
Creators: name: Susanto, Walsari Natasuwarna
Publisher: name: Canberra, ACT : The Australian National University
Year: 1982
Subjects: subject: Food crops Economic aspects Indonesia

description: The Government of Indonesia is greatly concerned with the need to increase food production especially rice as the preferred staple food. Several policies and programmes, intended to fill the gap between production and consumption, have been attempted. The import of rice caused a heavy drain on the foreign exchange earnings of Indonesia in the 1970s. These policies included intensification programmes in the form of InmaSj Bimas and Insus. The Bimas intensification programme induced improved cropping management along with increased fertilizer and insecticide use on irrigated land planted with the new highly responsive seeds. Intensification programmes were also started for non-rice food crops in the early seventies and were to be expanded rapidly during Reipelita III. Although rice and other food crops are produced in all regions in Indonesia, there exist big differences in the production patterns and potential among regions. Moreover, the distribution of production among regions varies from year to year due mainly to fluctuations in weather conditions. This study has two main objectives. Firstly, it tried to explain aggregate increases in basic food crop production by setting out a framework for assessing the contribution of area and yield to output growth in Indonesia since the 1950s. Indices of aggregate output of six basic food crops (rice, maize, cassava, sweet potatoes, peanuts and soybean) were analyzed for 25 provinces out of 27 provinces in Indonesia. Secondly, especially for rice production, the study examined the changes in yields over time by province and tried to explain changing yields in terms of irrigation improvement and fertilizer use. Fertilizer intensity was measured by the amount of fertilizer applied per hectare of cultivated areas. Irrigation contribution to output increase was examined by calculating the values of the irrigation ratio (i.e. the proportion of irrigated wet rice land to total wet rice land) and the values of irrigation rehabilitation ratio (i.e. the proportion of already rehabilitated rice land to total wet rice land). The study also discusses the present food policy of the Indonesian Government and issues for the future.

description: The peculiar motion of massive objects across the line of sight imprints a dipolar temperature anisotropy pattern on the cosmic microwave background known as the moving lens effect. This effect provides a unique probe of the transverse components of the peculiar velocity field, but has not yet been detected due to its small size. We implement and validate a stacking estimator for the moving lens signal using a galaxy catalog as a tracer of massive haloes combined with reconstructed velocities from the galaxy number density field. Using simulations, we forecast detection prospects for the moving lens signal from current and upcoming microwave background and galaxy surveys. We demonstrate a new foreground mitigation strategy likely sufficient for current data sets, and discuss various sources of systematic error and noise. Upcoming galaxy surveys will provide high significance statistical detections of the moving lens effect.

description: Recently, the full version of the Eigenstate Thermalization Hypothesis (ETH) has been systematized using Free Probability. In this paper, we present a detailed discussion of the Free Cumulants approach to many-body dynamics within the microcanonical ensemble. Differences between the later and canonical averages are known to manifest in the time-dependent fluctuations of extensive operators. Thus, the microcanonical ensemble is essential to extend the application of Free Probability to the broad class of extensive observables. We numerically demonstrate the validity of our approach in a non-integrable spin chain Hamiltonian for extensive observables at finite energy density. Our results confirm the full ETH properties, specifically the suppression of crossing contributions and the factorization of non-crossing ones, thus demonstrating that the microcanonical free cumulants encode ETH smooth correlations for both local and extensive observables.

description: By harnessing fiducial markers as visual landmarks in the environment, Unmanned Aerial Vehicles (UAVs) can rapidly build precise maps and navigate spaces safely and efficiently, unlocking their potential for fluent collaboration and coexistence with humans. Existing fiducial marker methods rely on handcrafted feature extraction, which sacrifices accuracy. On the other hand, deep learning pipelines for marker detection fail to meet real-time runtime constraints crucial for navigation applications. In this work, we propose YoloTag -a real-time fiducial marker-based localization system. YoloTag uses a lightweight YOLO v8 object detector to accurately detect fiducial markers in images while meeting the runtime constraints needed for navigation. The detected markers are then used by an efficient perspective-n-point algorithm to estimate UAV states. However, this localization system introduces noise, causing instability in trajectory tracking. To suppress noise, we design a higher-order Butterworth filter that effectively eliminates noise through frequency domain analysis. We evaluate our algorithm through real-robot experiments in an indoor environment, comparing the trajectory tracking performance of our method against other approaches in terms of several distance metrics.
The spatial organisation of corporations : a case study of the multinational chemicals industry with specific reference to ICI
Creators: name: Clarke, Ian M
Publisher: name: The Australian National University
Year: 1984
Subjects: subject: Corporations
subject: Chemical industry
subject: International business enterprises

description: This thesis is about the spatial implications of multinational corporations. It is argued that a better understanding of these spatial impacts can be achieved only by focusing on the complex organisation of corporate structures. Such an emphasis provides a supplementary perspective which can be used to explain the emergence of a new international division of labour during the 1970s and 1980s, a phenomenon which must be viewed partially as the outcome of the multinational evolution and restructuring of individual enterprises. The chosen theoretical perspective requires that a framework be established which provides a means of linking macro- and micro-scale processes operating in space, integrating propositions relating the organisation and spatial structure of corporations. The business organisation itself, therefore, is taken as the appropriate unit of analysis to gain insights into the position particular geographical events occupy within corporate space. Consequently, the analytical framework is derived from theories concerning the structure of business organisations. The argument is conducted within the context of business organisations operating in the chemicals industry between 1970 and 1980, special attention being given to one corporation, ICI. In particular, several conceptual problems on corporate structure are identified and addressed, concerning differentiation between and within organisations, and the role space plays in establishing, maintaining and increasing structural inequalities. The analysis expands the general arguments of the thesis, but also underlines the importance of historical patterns of corporate development which are embodied in organisational structures. Furthermore, the analysis both clarifies and exposes factors influencing the creation of a changing spatial division of labour, by emphasising the need to address processes operating inside individual plant locations, as well as inside different types of business organisation.

description: The structure of cometary dust is a tracer of growth processes in the formation of planetesimals. Instrumentation on board the Rosetta mission to comet 67P/Churyumov- Gerasimenko captured dust particles and analysed them in situ. However, these deposits are a product of a collision within the instrument. We conducted laboratory experiments with cometary dust analogues, simulating the collection process by Rosetta instruments (specifically COSIMA, MIDAS). In Paper I we reported that velocity is a key driver in determining the appearance of deposits. Here in Paper II we use materials with different monomer sizes, and study the effect of tensile strength on the appearance of deposits. We find that mass transfer efficiency increases from $\sim$1 up to $\sim$10% with increasing monomer diameter from 0.3 $μ$m to 1.5 $μ$m (i.e. tensile strength decreasing from $\sim$12 to $\sim$3 kPa), and velocities increasing from 0.5 to 6 m/s. Also, the relative abundance of small fragments after impact is higher for material with higher tensile strength. The degeneracy between the effects of velocity and material strength may be lifted by performing a closer study of the deposits. This experimental method makes it possible to estimate the mass transfer efficiency in the COSIMA instrument. Extrapolating these results implies that more than half of the dust collected during the Rosetta mission has not been imaged. We analysed two COSIMA targets containing deposits from single collisions. The collision that occurred closest to perihelion passage led to more small fragments on the target.

description: We discuss the possible existence of an observational window, in the TeV-PeV energy range, for the detection of prompt neutrinos from the decay of charmed particles produced in cosmic ray interactions with the atmosphere. We calculate the event rates for muon and tau neutrinos of heavy quark, mostly charm, origin. We argue that their prompt fluxes are observable in a kilometer-scale neutrino telescope, even though the calculations are subjected to large uncertainties, which we quantify. We raise the possibility that a small component of prompt neutrinos may already be present in the observed samples of current experiments. We also discuss the interplay of the predicted fluxes with those produced by the flavor oscillation of conventional atmospheric neutrinos, and by anticipated cosmic sources.

description: The level of systemic risk in economic and financial systems is strongly determined by the structure of the underlying networks of interdependent entities that can propagate shocks and stresses. Since changes in network structure imply changes in risk levels, it is important to identify structural transitions potentially leading to system-wide crises. Methods have been proposed to assess whether a real-world network is in a (quasi-)stationary state by checking the consistency of its structural evolution with appropriate maximum-entropy ensembles of graphs. While previous analyses of this kind have focused on dyadic and triadic motifs, hence disregarding higher-order structures, here we consider closed walks of any length. Specifically, we study the ensemble properties of the spectral radius of random graph models calibrated on real-world evolving networks. Our approach is shown to work remarkably well for directed networks, both binary and weighted. As illustrative examples, we consider the Electronic Market for Interbank Deposit (e-MID), the Dutch Interbank Network (DIN) and the International Trade Network (ITN) in their evolution across the 2008 crisis. By monitoring the deviation of the spectral radius from its ensemble expectation, we find that the ITN remains in a (quasi-)equilibrium state throughout the period considered, while both the DIN and e-MID exhibit a clear out-of-equilibrium behaviour. The spectral deviation therefore captures ongoing topological changes, extending over all length scales, to provide a compact proxy of the resilience of economic and financial networks.

description: We consider the quench of an atomic impurity via a single Rydberg excitation in a degenerate Fermi gas. The Rydberg interaction with the background gas particles induces an ultralong-range potential that binds particles to form dimers, trimers, tetramers, etc. Such oligomeric molecules were recently observed in atomic Bose-Einstein condensates. In this work, we demonstrate with a functional determinant approach that quantum statistics and fluctuations have observable spectral consequences. We show that the occupation of molecular states is predicated on the Fermi statistics, which suppresses molecular formation in an emergent molecular shell structure. At large gas densities this leads to spectral narrowing, which can serve as a probe of the quantum gas thermodynamic properties.

The economics of wet seeding : inducements to and consequences of some recent changes in Philippine rice cultivation

Year: 1984
Subjects: subject: Rice Planting Economic aspects Philippines
subject: Agricultural innovations Philippines

description: The objective of this study is to analyse the reasons for, and consequences of, adoption by farmers in Gapan, Nueva Ecija, Philippines of a new method of rice cultivation.The innovation is wet seeding of rice - the broadcasting of seed instead of transplanting of seedlings. It is thought that wet seeding, which is relatively capital-intensive compared to transplanting, has become economically feasible to farmers because agricultural factor markets in the Philippines are distorted in a way that reduces the price of capital relative to that of labour. Data for the study was collected by the author in the Philippines during January-May 1984. Two hypotheses are proposed and tested herein: that wet seeding is not technically more efficient than transplanting, and that by its substitution of capital inputs for human labour wet seeding is likely to represent a deterioration in equity. Chapter One introduces the theory of induced innovation, which maintains that innovations are adopted having factor-saving biases in accordance with movements in relative factor prices. The extension of this theory to the development of village institutions is also reviewed. In Chapter Two background material is presented, outlining the development of the present rice farming systems in Central Luzon, and investigating the various policy decisions of the Philippine Government in the last decade which have influenced factor and product prices faced by Central Luzon rice farmers. In Chapter Three the results of a survey of Gapan rice farmers are presented are discussed. Economic and econometric analyses conducted are reported in Chapter Four. Tests based upon regression analysis indicate difficulty in rejecting the hypothesis that wet seeding is no more technically efficient than transplanting. The results of partial budgets and other analysis tend to confirm the hypothesis that since efficiency is not increased while factor substitution is taking place, the distribution of income among the various in favour of those who have access to land, and against those who do not. Chapter Five looks more closely into the present employment situation and prospects of landless agricultural labourers in Gapan, reporting the findings of a series of 'key informant' interviews with local labour leaders and others. The findings of these interviews provide additional support for the hypothesis that adoption of wet seeding has made more skewed the distribution of income and opportunity in Gapan.

description: We have used existing optical emission and absorption lines, [C II] emission lines, and H I absorption lines to create a new model for a Central Column of material near the Trapezium region of the Orion Nebula. This was necessary because recent high spectral resolution spectra of optical emission lines and imaging spectra in the [C II] 158 micron line have shown that there are new velocity systems associated with the foreground Veil and the material lying between Theta 1 Ori C and the Main Ionization Front of the nebula. When a family of models generated with the spectral synthesis code Cloudy were compared with the surface brightness of the emission lines and strengths of the Veil absorption lines seen in the Trapezium stars, distances from Theta 1 Ori C, were derived, with the closest, highest ionization layer being 1.3 pc. The line of sight distance of this layer is comparable with the size of the inner Huygens Region in the plane of the sky. These layers are all blueshifted with respect to the Orion Nebula Cluster of stars, probably because of the pressure of a hot central bubble created by Theta 1 Ori C's stellar wind. We find velocity components that are ascribed to both sides of this bubble. Our analysis shows that the foreground [C II] 158 micron emission is part of a previously identified layer that forms a portion of a recently discovered expanding shell of material covering most of the larger Extended Orion Nebula.

description: A feed-forward photonic neural network (PNN) is tested for chromatic dispersion compensation in Intensity Modulation/Direct Detection optical links. The PNN is based on a sequence of linear and nonlinear transformations. The linear stage is constituted by an 8-tap time-delayed complex perceptron implemented on a Silicon-On-insulator platform and acting as a tunable optical filter. The nonlinear stage is provided by the square modulus of the electrical field applied at the end-of-line photodetector. The training maximizes the separation between the optical levels (i.e. the eye diagram aperture), with consequent reduction of the Bit Error Rate. Effective equalization is experimentally demonstrated for 20 Gbps 4-level Pulse Amplitude Modulated signal up to 125 km. An evolutionary algorithm and a gradient-based approach are tested for the training and then compared in terms of repeatability and convergence time. The optimal weights resulting from the training are interpreted in light of the theoretical transfer function of the optical fiber. Finally, a simulative study proves the scalability of the layout to larger bandwidths, up to 100 Gbps.

description: A substantial amount of China’s rapid economic growth in has been attributed to its large proportion of rural-urban migrants, but more than 80% of these migrants’ children are still left in rural areas mainly due to China’s household registration system. Identification of the impact of parental migration on children’s school performance may encounter the problem of endogeneity. Using unique survey data collected from Qinghai Province and the Ningxia Autonomous Region in Northwestern China where more than 7,100 Grade 4 & 5 students from 74 rural elementary schools participated and by the instrumental-variable estimation, our results indicate that parents’ decisions to migrate are exogenous to their children’s schooling performance, and one more migratory parent can marginally reduce their child’s math score by 1.73 percent in percentile rank, which implies that the current economic growth in China partially jeopardizes the future of the next rural generation. In addition, we find a causal relationship between the poor performance of ethnic minorities and both geographical and social disadvantages.
Scalar-tensor theories of gravity from a thermodynamic viewpoint

description: In any diffeomorphism invariant theory of gravity, one can define a Noether charge arising from the invariance of the Lagrangian under diffeomorphisms. We have determined the Noether charge for scalar-tensor theories of gravity, in which case the gravity is mediated by the metric tensor as well as by a scalar degree of freedom. In particular, we demonstrate that the total Noether charge within an appropriate spatial volume can be related to the heat content of the boundary surface. For static spacetimes, in these theories, there exist an ``equipartition" between properly defined bulk and surface degrees of freedom. While the dynamical evolution of spacetime in these theories of scalar-tensor gravity arises due to the departure from the equipartition regime. These results demonstrate that thermodynamical interpretations for gravitational theories transcend Einstein and Lovelock theories of gravity, holding true for theories with additional scalar degrees of freedom as well. Moreover, they hold in both the Jordan and the Einstein frames. However, it turns out that there are two dynamically equivalent representations of the scalar-tensor theory in the Jordan frame, differing by total derivatives in the action, which are thermodynamically inequivalent. This depicts the importance of having a thermodynamic description, which can be used in distinguishing various dynamically equivalent representations of gravity theories beyond Einstein.

description: In the minimal supersymmetric standard model (MSSM) properties of the third generation sfermions are important from the viewpoint of discriminating the SUSY breaking models and in the determination of the Higgs boson mass. If gluinos are copiously produced at CERN LHC, gluino decays into tb through stop and sbottom can be studied using hadronic decays of the top quark. The kinematical endpoint of the gluino decays can be evaluated using a W sideband method to estimate combinatorial backgrounds. This implies that fundamental parameters related to the third generation squarks can be reliably measured. The top-quark polarization dependence in the decay process may also be extracted by looking at the b jet distribution near the kinematical endpoint.

Supply response of cotton between the government and the growers in the Sudan
Creators: name: Abdalla, Ali Abdelrazig
Publisher: name: The Australian National University
Year: 1984
Subjects: subject: Cotton trade Government policy Sudan

description: Cotton is the single most important crop and plays a decisive role in the national economy of the Sudan. Besides being the largest source of the country's foreign exchange earnings, it contributes considerably to the growers' cash income. In the light of the economic importance of cotton this study has been conducted to investigate response behaviour in its production. The response analysis of the government on the one hand, and of the growers on the other, were carried out separately. This is justified by the assumption that the two partners, though functioning objectively, are operating according to different objective functions. Time series data for 19 years (1962/63-1980/81) were analysed to estimate the government's supply response of cotton. Response studies of total area under cotton and of the area under different cotton varieties were conducted. From the results it has been found that the government responds to the relative profitability of medium staple, short staple and aggregate total cotton. The elasticities of response were found to be 0.55, 0.38 and 0.13 in the short-run, and 0.92, 0.43 and 0.15 in the long-run, for medium staple, short staple and total cotton, respectively. For the growers' function, time series data for 15 years (1967/68-1981/82) were used for the estimation of the average yield response to price changes. The average yield was used as the response variable because the area planted to cotton is government controlled. Three major production regions, located in different parts of the country and growing different types of cotton, were selected for the analyses. The estimated results revealed the weak responsiveness of the average yield of cotton to price changes for all of the three types. In the light of the inadequate results obtained from the grower's function, concrete policy recommendations were not made in this study.
Terms of trade for coffee and economic performance of Ethiopia
Creators: name: Yainshet, Alasebu
Publisher: name: Canberra, ACT : The Australian National University
Year: 1984
Subjects: subject: Coffee industry Ethiopia

description: This sub-thesis examines the trend and fluctuations in the commodity and income terms of trade for Ethiopia's coffee. Given the importance of the coffee sector, an analysis is undertaken on the impact of the trend and fluctuations of the income terms of trade for coffee on major macro-variables of the country. The study commences with a discussion on the objectives, methodology and data sources followed by background details of the micro-sector of the coffee economy and of the macro-economic conditions in which it functions. Then a review of relevant theoretical and empirical literature on terms of trade is given. Since supply and demand for coffee are important in the determination of the terms of trade, they are discussed at both the international and the domestic level. The need to discuss the international demand and supply of coffee arises because of the fact that Ethiopia is a price taker in the World coffee market. The proposition that commodity and income terms of trade deteriorated during the period under consideration is tested and no deterioration was observed. Finally the impact of the trend and fluctuations in the income terms of trade on major economic variables capital goods imports and gross domestic capital formation are analyzed. Significant relationships are found in all cases except with fluctuations in the income terms of trade for coffee computed from the extrapolated trend and fluctuations in gross domestic capital formation.
