description: Angular-resolved photoemission data on half-filled doped cuprate materials are compared with an exact-diagonalization analysis of the three-band Hubbard model, which is extended to the infinite lattice by means of a perturbation in the intercluster hopping (cluster perturbation theory). A study of the band dispersion and spectral weight of the insulating cuprate Sr$_2$CuO$_2$Cl$_2$ allows us to fix a consistent parameter set, which turns out to be appropriate at finite dopings as well. In the overdoped regime, our results for the spectral weight and for the Fermi surface give a good description of the experimental data on Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$. In particular, the Fermi surface is hole-like and centered around $k=(π,π)$. Finally, we introduce a hopping between two layers and address the issue of bilayer splitting.

Strengths of qualitative research in social work’s “policy practice”
Creators: name: Santos, Clara Cruz
name: Albuquerque, Cristina Pinto
Publisher: name: Sensos-e
Year: 2018

description: In this article we defend the argument that the immersion of qualitative research in social worker’s daily practice, allowing its supra immediacy comprehension and analysis, can increase social work’s “policy practice”. The possibility to influence policies, to assess and build renewed responses to structural constraints and social injustices, and to critically discuss and influence service’s functioning and power structures is very connected with the ways of construction and use of practice-based evidences. Qualitative research can be used by social workers in daily practice to achieve these goals. By the use of comprehensive approaches qualitative research gives significance to politics’ concepts and highlights the impacts of policies and intervention on people and territories. This argument is based on two main assumptions: (i) The qualitative research allows joining analytically fragments of social reality, identifying common patterns under the appearance of daily practice heterogeneity, and (ii) It permits the systematization of data over the apparent chaotic discourses without neutralizing the uniqueness of personal narratives.

Uranium-series dating of corals from the southwest Pacific
Creators: name: Marshall, John F.
Publisher: name: The Australian National University
Year: 1975

description: The uranium-series technique is based on the observation that carbonates precipitating in nature, in particular corals and oolites, show an initial disequilibrium between Th²³⁰ and its parent U²³⁸. The amount of Th²³⁰ initially present in a coral is negligible in comparison to that subsequently generated by the radioactive decay of uranium. If the system remains closed then the ratio of Th²³⁰ to U²³⁸ is a simple function of time. Because there is a 15 percent excess of U²³⁴ to U²³⁸ in sea water this has to be taken into account when determining the age. Corals from New Guinea, the Loyalty Islands, and the east coast of Australia were provided for dating. The New Guinea corals, from the Huon Peninsula, had been dated previously, and so they provided a check on the reliability of the techniques used in this study. With one exception the ages from this study are within the error limits placed on the original ages. The one sample that does not agree is shown to have a high proportion-of void-filling low-Mg calcite cement. Corals from the Capricorn Group and Hayman Island within the Great Barrier Reef province show relatively young ages. One coral recovered by drilling at a depth of 17m on the Hayman Island reef indicates that the time of recolonization of the reef towards the end of the Holocene transgression is about 8,300 yr B.P. Coral samples below a marked discontinuity at a depth of about 20m are extensively recrystallized. Ages of corals from the Inner Barrier of New South Wales show that this feature 'formed during the last inter-glacial at about 120,000 yr B.P. The ages suggest that there were two periods of high sea level at about this time. Ages from reef terraces 2-6m above present sea level from three islands of the Loyalty Archipelago show the varying degrees of uplift of these islands. Corals from +2m on Beautemps-Beaupre are older than 200,000 yr B.P., while a coral at +6.5m from Ouvea gave an age of 117,000 ± 6,000 yr B.P. Ages from the +2m terrace on Lifou support the interpretation of a relatively high sea level at about 180,000 yr B.P. Ages of corals from a slightly raised fringing reef around Mud Island, Moreton Bay indicate a sea level about one metre higher than present during the interval 4,000 - 6,000 yrs B.P. This slightly higher sea level could have been the result of a changing.tidal regime within the bay.

description: We present the conditional quantum dynamics of an electron tunneling between two quantum dots subject to a measurement using a low transparency point contact or tunnel junction. The double dot system forms a single qubit and the measurement corresponds to a continuous in time readout of the occupancy of the quantum dot. We illustrate the difference between conditional and unconditional dynamics of the qubit. The conditional dynamics is discussed in two regimes depending on the rate of tunneling through the point contact: quantum jumps, in which individual electron tunneling current events can be distinguished, and a diffusive dynamics in which individual events are ignored, and the time-averaged current is considered as a continuous diffusive variable. We include the effect of inefficient measurement and the influence of the relative phase between the two tunneling amplitudes of the double dot/point contact system.

Subjects: subject: Linguistics
subject: FOS: Languages and literature

description: In Linguistics, mutual influence of languages is the most actual issue. In this way, influence of Spanish language on English and vice versa is an obvious example. Both languages have huge numbers of native speakers. They are both spoken as native or official languages over the vast geographical areas which cover a large number of countries. They are both official languages of the United Nations and many other international organizations. Subsequently, features of these languages really draw our attention. The mutual influence between Spanish and English languages started centuries ago and is being continued to recently. The same roots of languages and massive process of globalization play the most important role in mutual influence. Influence in languages makes similarities that might be both positive and negative. The fact that sometimes one word in two languages has different meanings makes speakers confused and they mistake easily.The aim of this research is to introduce theories and examples for explaining the influences between Spanish and English. Major research includes analysis of famous writers’ works with qualitative method. ‘Don Quixote’ by Miguel De Cervantes, ‘The family of Pascual Duarte’ by Camilo Jose Cela and ‘Invisible Man’ by Ralph Elisson - in these works, similar linguistic aspects and examples are found, which prove that two languages have strongly influenced on each other.

 Chlorospingus pileatus diversus Griscom, 1924a: 11 (Cerro Flores, alt. 6000 ft., eastern Chiriqui, Panama).
 Now Chlorospingus pileatus diversus Griscom, 1924. See Hellmayr, 1936: 409, Wetmore et al., 1984: 497–498, Isler and Isler, 1999: 66–67, and Dickinson, 2003: 818.
 HOLOTYPE: AMNH 183044, adult male, collected on Cerro Flores, 5500 ft, 08.29N, 81.44W (Siegel and Olson, 2008), Chiriqui, Panama, on 14 March 1924, by Ludlow Griscom and Rex Benson.
 COMMENTS: Griscom cited the AMNH number of the holotype in the original description and noted that he had six specimens, including the type. The five paratypes are: AMNH 183043, 183045– 183048, one male and four females, all from Cerro Flores, collected 14 to 18 March 1924. Some authors consider diversus a synonym of nominate pileatus. Griscom (1924b) wrote a popular account of this expedition.
See Siegel and Olson (2008: 168–169) for a discussion of this type locality. The altitude at which the holotype was collected was said in the original description to be 6000 ft, but both the field label and the AMNH label record this as 5500 ft.

description: We calculate the probability distribution of the local density of states $ν$ in a disordered one-dimensional conductor or single-mode waveguide, attached at one end to an electron or photon reservoir. We show that this distribution does not display a log-normal tail for small $ν$, but diverges instead $\proptoν^{-1/2}$. The log-normal tail appears if $ν$ is averaged over rapid oscillations on the scale of the wavelength. There is no such qualitative distinction between microscopic and mesoscopic densities of states if the levels are broadened by inelastic scattering or absorption, rather than by coupling to a reservoir.

description: Typical measurements of nanowire devices rely on end-to-end measurements to reveal mesoscopic phenomena such as quantized conductance or Coulomb blockade. However, creating nanoscale tunnel junctions allows one to directly measure other properties such as the density of states or electronic energy distribution functions. In this paper, we demonstrate how to realize uniform tunnel junctions on InSb nanowires, where the low invasiveness preserves ballistic transport in the nanowires. The utility of the tunnel junctions is demonstrated via measurements using a superconducting tunneling probe, which reveal non-equilibrium properties in the open quantum dot regime of an InSb nanowire. The method for high-quality tunnel junction fabrication on InSb nanowires is applicable to other III-V nanowires and allows for new tools to characterize the local density of states.
The relationship between the nutrient status and flammability of forest fuels
Creators: name: Mak, Edwin Hon Tak
Publisher: name: The Australian National University
Year: 1982

description: An investigation is reported of the relationships between nutrient status of foliar and litter materials from Australian forests and the three components of flammability, namely, ignitability, sustainability, and combustibility. The Limiting Oxygen Index (LOI) method was chosen as an index of ignitability and sustainability, and combustibility has been measured by Thermogravimetric Analysis . (TGA) and Derivative Thermogravimetric Analysis (DTG). Results derived from LOI and TGA are seen to be more reproducible and reliable than other methods commonly used in m~asuring forest fuel flammability. The first study examines the general relationship between a number of chemical attributes and the flammability of the leaves of 47 species. A significant correlation between nutrient status and flammability was found, foliar calcium in particular, appearing to have most effect on flammability. Because of this, the major study involves a comprehensive evaluation of relationships between flammability and nutrient concentrations in green foliage, freshly fallen leaves, and litter decomposing on the forest floor. Thirteen species have been used, drawn from the vegetational gradient, dry sclerophyll forest to rainforest. Ignitahility and sustainability of forest fuels are greater in materials with lower nutrient concentrations, including the eucalypts, although there are exceptions to this generalisation. Alternatively, combustibility, as defined by the TGA technique, is lower in foliar and litter materials with low nutrient status, again including the eucalypts. The three flammability indices do not appear to respond directly to seasonal variations in nutrient concentrations in green foliage or changes in nutrient concentrations during the decomposition process. However, flammability generally increases at leaf senescence and litter fall, during which substantial amounts of nitrogen, phosphorus, and potassium are withdrawn and calcium is accumulated. A number of characteristics of the eucalypt forest contribute to its considerable flammability. 'These include the slow decomposition rate of eucalypt litter, the physical structure of the litter layer, the ignitability and sustainability of eucalypt litter, and a number of combustion characteristics. The relevance of the standard TGA index of combustibility is reviewed and an alternate index suggested, which may be more appropriate to the flaming combustion of the forest floor. It is concluded that low nutrient concentrations and flammability in eucalypt are related, but possibly in an indirect evolutionary way. The evolutionary response of eucalypts and other species to low nutrient soils may have involved changes in the structure and components of leaf tissues contributing to their particular flammability characteristics.

description: We measure the bulk system parameters of the seismically active, rapidly-rotating $δ$-Scuti KOI-976 and constrain the orbit geometry of its transiting binary companion using a combined approach of asteroseismology and gravity-darkening light curve analysis. KOI-976 is a $1.62\pm0.2~\mathrm{M_\odot}$ star with a measured $v\sin(i)$ of $120\pm2$ km/s and seismically-induced variable signal that varies by $\sim$ 0.6\% of the star's total photometric brightness. We take advantage of the star's oblate shape and seismic activity to perform three measurements of its obliquity angle relative to the plane of the sky. We first apply rotational splitting theory to the star's variable signal observed in short-cadence \emph{Kepler} photometry to constrain KOI-976's obliquity angle, and then subtract off variability from that dataset using the linear algorithm for significance reduction software {\tt LASR}. We perform gravity-darkened fits to \emph{Kepler} variability-subtracted short-cadence photometry and to \emph{Kepler's} phase-folded long-cadence photometry to obtain two more measurements of the star's obliquity. We find that the binary system transits in a grazing configuration with measured obliquity values of $36^\circ\pm17^\circ$, $46^\circ\pm16^\circ$, and $43^\circ\pm20^\circ$ respectively for the three measurements. We perform these analyses as a way to demonstrate overcoming the challenges high-mass stars can present to transit light curve fitting and to prepare for the large number of exoplanets \emph{TESS} will discover orbiting A/F stars.

description: FeSn is a room-temperature antiferromagnet expected to host Dirac fermions in its electronic structure. The interplay of magnetic degree of freedom and the Dirac fermions makes FeSn an attractive platform for spintronics and electronic devices. While stabilization of thin film FeSn is needed for the development of such devices, there exist no previous report of epitaxial growth of single crystalline FeSn. Here we report the realization of epitaxial thin films of FeSn (001) grown by molecular beam epitaxy on single crystal SrTiO$_{3}$ (111) substrates. By combining X-ray diffraction, electrical transport, and torque magnetometry measurements, we demonstrate the high quality of these films with the residual resistivity ratio $ρ_{xx}(300 \hspace{0.2em}{\rm K})/ρ_{xx}(2 \hspace{0.2em}{\rm K}) = 24$ and antiferromagnetic ordering at $T_{\rm N}$ = 353 K. These developments open a pathway to manipulate the Dirac fermions in FeSn by both magnetic interactions and the electronic field effect for use in antiferromagnetic spintronics devices.

description: We compare the results of constructing binary black hole initial data with three different decompositions of the constraint equations of general relativity. For each decomposition we compute the initial data using a superposition of two Kerr-Schild black holes to fix the freely specifiable data. We find that these initial-data sets differ significantly, with the ADM energy varying by as much as 5% of the total mass. We find that all initial-data sets currently used for evolutions might contain unphysical gravitational radiation of the order of several percent of the total mass. This is comparable to the amount of gravitational-wave energy observed during the evolved collision. More astrophysically realistic initial data will require more careful choices of the freely specifiable data and boundary conditions for both the metric and extrinsic curvature. However, we find that the choice of extrinsic curvature affects the resulting data sets more strongly than the choice of conformal metric.

description: The Hartree-Fock based diagonalization is a computational method for the investigation of the low-energy properties of correlated electrons in disordered solids. The method is related to the quantum-chemical configuration interaction approach. It consists in diagonalizing the Hamiltonian in a reduced Hilbert space built of the low-energy states of the corresponding disordered Hartree-Fock Hamiltonian. The properties of the method are discussed for the example of the quantum Coulomb glass, a lattice model of electrons in a random potential interacting via long-range Coulomb interaction. Particular attention is paid to the accuracy of the results as a function of the dimension of the reduced Hilbert space. It is argued that disorder actually helps the approximation.

It is non-trivial and non-optimal to manually create placement rules for scheduling that would decide which applications should co-locate. In this paper, we present DeepPlace, a scheduler that learns to exploits various temporal resource usage patterns of applications using Deep Reinforcement Learning (Deep RL) to reduce resource competition across jobs running in the same machine while at the same time optimizing for overall cluster utilization.

description: Superconducting mechanism mediated by interband exchange Coulomb repulsion is examined in an extended two-band Hubbard models with a wide band crossing the Fermi level and coexisting with a narrower band located at moderately lower energy. We apply newly developed path-integral renormalization group method to reliably calculate pairing correlations. The correlation shows marked enhancement at moderate amplitudes of the exchange Coulomb repulsion taken smaller than the on-site repulsion for the narrower band. The pairing symmetry is s-wave while it has unconventional phases with the opposite sign between the order parameters on the two bands, in agreement with the mean-field prediction. Since the band structure of recently discovered superconductor MgB$_2$ shares basic similarities with our model, we propose that the present results provide a relevant clue for the understanding of the superconducting mechanism in MgB$_2$ as well as in this class of multi-band materials with good metallic conduction in the normal state.

description: Nuclear data libraries (ENDF, JEFF, JENDL, CENDL, etc.) document our phenomenological knowledge of nuclear cross sections as interpreted by R-matrix theory. The R-matrix scattering model can parameterize the energy dependence of the scattering matrix in different ways. This article establishes new results on three such sets of parameters: the Wigner-Eisenbud, the Brune, and the Siegert-Humblet parameters. We show how the latter two arise from invariance to the arbitrary boundary condition, and how they can trade-off more complex parameters for a simpler energy dependence parameterization: the scattering matrix pole expansion of Humblet and Rosenfeld. We establish that the scattering matrix's invariance to channel radius sets a partial differential equation on the widths of the Kapur-Peierls operator, which enables us to derive an explicit transformation of the Siegert-Humblet radioactive residue widths under a change of channel radius. Considering the continuation of the scattering matrix to complex wavenumbers, several new results are established. We unveil there exist more Brune parameters than previously thought, depending on the way the scattering matrix is continued to complex energies. This points to a broader conundrum in the field: how to analytically continue the scattering matrix while closing sub-threshold channels. We argue that, contrary to the Lane and Thomas legacy of force-closing sub-threshold channels which introduces spurious poles, analytic continuation is the physically correct way of defining the scattering matrix for complex wave numbers. To back this claim we establish thee results: analytic continuation cancels spurious poles, enforces the generalized unitarity conditions of Eden and Taylor, and closes massive particle channels below threshold by both quantum tunneling and from the definition of the cross section as the ratio of probability currents.

Zoom & Whirl: Eccentric equatorial orbits around spinning black holes and their evolution under gravitational radiation reaction

description: We study eccentric equatorial orbits of a test-body around a Kerr black hole under the influence of gravitational radiation reaction. We have adopted a well established two-step approach: assuming that the particle is moving along a geodesic (justifiable as long as the orbital evolution is adiabatic) we calculate numerically the fluxes of energy and angular momentum radiated to infinity and to the black hole horizon, via the Teukolsky-Sasaki-Nakamura formalism. We can then infer the rate of change of orbital energy and angular momentum and thus the evolution of the orbit. The orbits are fully described by a semi-latus rectum $p$ and an eccentricity $e$. We find that while, during the inspiral, $e$ decreases until shortly before the orbit reaches the separatrix of stable bound orbits (which is defined by $p_{s}(e)$), in many astrophysically relevant cases the eccentricity will still be significant in the last stages of the inspiral. In addition, when a critical value $p_{crit}(e)$ is reached, the eccentricity begins to increase as a result of continued radiation induced inspiral. The two values $p_{s}$, $p_{crit}$ (for given $e$) move closer to each other, in coordinate terms, as the black hole spin is increased, as they do also for fixed spin and increasing eccentricity. Of particular interest are moderate and high eccentricity orbits around rapidly spinning black holes, with $p(e) \approx p_{s}(e)$. We call these ``zoom-whirl'' orbits, because of their characteristic behaviour involving several revolutions around the central body near periastron. Gravitational waveforms produced by such orbits are calculated and shown to have a very particular signature. Such signals may well prove of considerable astrophysical importance for the future LISA detector.

Year: 1988
Subjects: subject: China History Self strengthening movement, 1861-1895
subject: China History Reform movement, 1898
subject: China History 19th century

description: This thesis is focused on the ideals and activities of the qingliu group during two major political movements, the self-strengthening (ziqiang) and reform (bianfa) movements, between the 1860s and 1890s. The qingliu group was a political faction of the "scholar-officials" (shidafu). In particular, the members of the group comprised the more distinguished of the scholar-officials. Most of the members of the qingliu group held positions in the Hanlin Academy, the Censorate or other official bodies and the Court could ill-afford to ignore their opinions, or qingyi (literally 'pure discussion,’ also translated as 'public opinion'). As a result, the ideas and actions of the qingliu group greatly influenced state politics, and the group played an important and dominant role in late Qing history.
Education, opportunity and social change : the development of a Catholic university elite in Ireland, 1879-1922

Subjects: subject: Catholic Church Education Ireland

subject: Ireland History 19th century

description: This thesis explores the development of a Catholic university elite in Ireland, 1878-1922. The provision of education, especially university education, in late nineteenth and early twentieth century Ireland is the main focus of this thesis. Central to this study is an investigation of how access to higher education facilitated elevated social, political and economic status for a privileged section of the Irish Catholic community. The role of education as a carrier of ideas and as a form of social interaction is also considered. A central aim of this thesis is t9 bring to the exploration of the education debate the voices of Catholic students themselves. Therefore, the experiences of a sample group of 51 Catholic graduates in 1891 and 1901 from the Royal University of Ireland and Trinity College, Dublin, are discussed throughout the thesis, although other prominent individuals are also considered. Such an approach affords an intimate understanding of the way education influenced and empowered middle-class Catholics - an increasingly important and ambitious stratum in Irish society. The experiences of the sample group and their university colleagues reveal much about fin de siecle Ireland. Another central aim of this thesis is to re-examine the vital but under-studied years between the fall of C. S. Parnell in 1891 and the Easter Rising in 1916. The experiences of the sample group testify to the dynamism of the period and illuminate significant social and political change. Moreover, they challenge central aspects of Irish historiography of this period. Not only did university students overwhelmingly support constitutional Home Rule and eschew separatism, they actively promoted themselves as future leaders of a Home Rule Ireland. In preparation for their future roles as political leaders, they embraced educational, professional and social forms based on British models. Significantly, they paid little more than superficial attention to the condemnation of cultural nationalists who denounced as 'un-Irish' students' foray into high political, social and professional circles. Although some students made conciliatory gestures to Irish cultural revivalism, pragmatic and modem considerations took precedence over Gaelicist rhetoric in the spheres of education, employment and politics. The Great War and subsequent contingent events arrested the ascension of the Catholic university elite to dominance of Irish political and social life, deeming them a lost generation of Irish leaders. This thesis explores their political, professional and cultural development and through them salient issues in late nineteenth and early twentieth century Ireland.
Spanish Language Influence on English Language and Vice Versa

subject: FOS: Languages and literature

description: In Linguistics, mutual influence of languages is the most actual issue. In this way, influence of Spanish language on English and vice versa is an obvious example. Both languages have huge numbers of native speakers. They are both spoken as native or official languages over the vast geographical areas which cover a large number of countries. They are both official languages of the United Nations and many other international organizations. Consequently, features of these languages really draw our attention. The mutual influence between Spanish and English languages started centuries ago and is being continued to recently. The same roots of languages and massive process of globalization play the most important role in mutual influence. Influence in languages makes similarities that might be both positive and negative. The fact that sometimes one word in two languages has different meanings makes speakers confused and they mistake easily.The aim of this research is to introduce theories and examples for explaining the influences between Spanish and English. Major research includes analysis of famous writers’ works with qualitative method. ‘Don Quixote’ by Miguel De Cervantes, ‘The family of Pascual Duarte’ by Camilo Jose Cela and ‘Invisible Man’ by Ralph Elisson - in these works, similar linguistic aspects and examples are found, which prove that two languages have strongly influenced on each other.The aim of this research is to introduce theories and examples for explaining the influences between Spanish and English.

description: A TiS$_{2}$ crystal with a layered structure was found to have a large thermoelectric power factor.The in-plane power factor $S^{2}/ ρ$ at 300 K is 37.1~$μ$W/K$^{2}$cm with resistivity ($ρ$) of 1.7 m$Ω$cm and thermopower ($S$) of -251~$μ$V/K, and this value is comparable to that of the best thermoelectric material, Bi$_{2}$Te$_{3}$ alloy. The electrical resistivity shows both metallic and highly anisotropic behaviors, suggesting that the electronic structure of this TiS$_{2}$ crystal has a quasi-two-dimensional nature. The large thermoelectric response can be ascribed to the large density of state just above the Fermi energy and inter-valley scattering. In spite of the large power factor, the figure of merit, $ZT$ of TiS$_{2}$ is 0.16 at 300 K, because of relatively large thermal conductivity, 68~mW/Kcm. However, most of this value comes from reducible lattice contribution. Thus, $ZT$ can be improved by reducing lattice thermal conductivity, e.g., by introducing a rattling unit into the inter-layer sites.

description: We show that the continuum limit of the tilted Dirac cone in materials such as $8Pmmn$-borophene and layered organic conductor $α$-(BEDT-TTF)$_2$I$_3$ deformation of the Minkowski spacetime of Dirac materials. From its Killing vectors we construct an emergent tilted-Lorentz (t-Lorentz) symmetry group for such systems. With t-Lorentz transformations we are able to obtain the exact solution of the Landau bands for a crossed configuration of electric and magnetic fields. For any given tilt parameter $0\leζ<1$ if the ratio $χ=v_FB_z/cE_y$ of the crossed magnetic and electric fields that satisfies $χ\ge 1+ζ$ one can always find appropriate t-boosts in both valleys labeled by $\pm$ in such a way the electric field can be t-boosted away, whereby the resulting pure effective magnetic field $B^\pm_z$ governs the Landau level spectrum around each valley. The effective magnetic field in one of the valleys is always larger than the applied perpendicular magnetic field. This amplification comes at the expense of of diminishing the effective field in the opposite valleyand can be detected in various quantum oscillation phenomena in tilted Dirac cone systems. Tuning the ratio of electric and magnetic fields to $χ_{\rm min}=1+ζ$ leads to valley selective collapse of Landau levels. Our geometric description of the tilt in Dirac systems reveals an important connection between the tilt and an incipient "rotating source" when the tilt parameter can be made to depend on spacetime in certain way.

Technical progress in agriculture, income distribution and economic policy : the Philippines, 1950-80
Creators: name: Coxhead, Ian A

Year: 1989
Subjects: subject: Agricultural innovations Philippines
subject: Income distribution Philippines
subject: Philippines Economic policy

description: Successive Philippine governments since world war II have pursued a development strategy predicated upon industrial growth. Through such policy instruments as exchange rate overvaluation, tariffs on imports of consumer goods, and export taxes on agriculture, capital has been directed into industry - and especially the manufacturing sector - both from abroad and from out of agriculture. The growth of the protected industrial sector has been achieved at the cost of periodic trade balance crises, and a persistent maldistribution of income between rural households (which are largely dependent on agriculture) and their urban counterparts. Within the agricultural sector, public investment, subsidies, credit programs, research and extension have been focused on food crop producers in the most favourable (irrigated) agricultural areas, especially those in the Manila hinterland regions of Central Luzon and Southern Tagalog. Agricultural producers in less well developed regions have been doubly taxed: once by the economy-wide bias against agriculture, and a second time relative to other agricultural producers by the "irrigation bias" of public spending on agricultural development. A faster rate of technical progress in the areas favoured with better quality land endowments and public policy support has further disadvantaged producers in other agricultural areas by driving down real product prices and raising the real prices of mobile factors. Empirical partial equilibrium analyses of the distributional effects of new technologies have failed to capture these indirect costs of technological innovation. In this thesis a simple Johansen-style general equilibrium model is developed for the analysis of changes in prices and technology in stylised well-irrigated and poorlyirrigated agricultural environments. The model’s parameters of agricultural factor demand, supply response and technical change are estimated from Philippine data. Hypothetical and empirically measured technical change shocks are applied to the model. In this way the ceteris paribus effects of technical progress are assessed for their impact on wages, sectoral employment and factor intensity, and the functional and household distributions of income.
