description: The eclipsing binary system 2M 1938+4603 consists of a pulsating hot subdwarf B star and a cool M dwarf companion in an effectively circular three-hour orbit. The light curve shows both primary and secondary eclipses, along with a strong reflection effect from the cool companion. Here we present constraints on the component masses and eccentricity derived from the Rømer delay of the secondary eclipse. Using six months of publicly-available Kepler photometry obtained in Short Cadence mode, we fit model profiles to the primary and secondary eclipses to measure their centroid values. We find that the secondary eclipse arrives on average 2.06 +/- 0.12 s after the midpoint between primary eclipses. Under the assumption of a circular orbit, we calculate from this time delay a mass ratio of q = 0.2691 +/- 0.0018 and individual masses of M_sd = 0.372 +/- 0.024 Msun and M_c = 0.1002 +/- 0.0065 Msun for the sdB and M dwarf, respectively. These results differ slightly from those of a previously-published light curve modeling solution; this difference, however, may be reconciled with a very small eccentricity, e cos ω ~ 0.00004. We also report an orbital period decrease of P-dot = (-1.23 +/- 0.07) x 10^-10.

description: Differently from the canonical seesaw mechanism, which is grounded in grand unified theories, the inverse seesaw mechanism lacks a special framework that realizes it naturally. In this work we advocate that the 3-3-1 model with right-handed neutrinos has such an appropriate framework to accommodate the inverse seesaw mechanism. We also provide an explanation for the smallness of the $μ$ parameter and estimate the branching ratio for the rare lepton flavor violation process $μ\rightarrow eγ$.

The enforceability of conservation easement agreements in Alberta
Creators: name: Row, Victoria Wismer
Publisher: name: Law

description: Bibliography: p. 106-115
description: Conservation easement agreements may be granted by landowners for the purpose of conserving, protecting and enhancing the environment including biological diversity, natural scenic and esthetic values on privately owned land as authorized by clauses 22(2)(a)(b) and (c) of the Environmental Protection and Enhancement Act. The goal of this thesis is to analyze whether conservation easements registered on the certificates of title to land in Alberta will be enforceable against the original grantors and subsequent owners of the land. Some of the purposes of the conservation easement agreements collected may not fall within the statutory purposes. An analysis of the terms of the conservation easements collected shows that there are restrictions on the uses of land; however, there are exemptions to those restrictions. Some essential terms in the restrictions and exemptions are undefined and may be void for uncertainty. Because conservation easements are similar to restrictive covenants they may be strictly construed. Challenges to the enforceability of conservation easement agreements may be reduced by including provisions that deal with third party impacts including resource development and access easements, interpretation, severability, amendment, modification, baseline reports, and general restructions and residual rights. There may be remedies, such as severance and modification pursuant to subsection 48( 4) of the Land Titles Act or clauses 22(7)( a) and (b) of the Environmental Protection and Enhancement Act, and amendment by agreement which a court might use to save an otherwise unenforceable conservation easement agreement. There are dispute resolution mechanisms including arbitration available to the parties to reduce the time, effort and expense of resolving disputes.
Investigation of high performance single-phase solutions for AC-DC power factor corrected boost converters

Publisher: name: University of British Columbia
Year: 2011

description: Plug-in Hybrid Electric Vehicles (PHEVs) and Electric Vehicles (EVs) are an emerging trend in automotive circles, and consumer’s interest is growing rapidly. With the development of PHEVs, battery chargers for automotive applications are becoming a large market for the power supply industries. The improvement of overall charger efficiency is critical for the emergence and acceptance of these vehicular technologies, as the charger efficiency increases, the charge time and utility cost decreases. Additionally, to meet the efficiency and power factor requirements and regulatory standards for the AC supply mains, power factor correction is essential. Due to limited space in vehicle and increasing power consumption, chargers are required to deliver more power with smaller volume. As a key component of a charger system, the frontend AC-DC converter must achieve high efficiency and high power density. In this dissertation, several conventional plug in hybrid electric vehicle charger front end AC-DC converter topologies are investigated and a new bridgeless interleaved and a phase shifted semi-bridgeless power factor corrected converter are proposed to improve the efficiency and performance, which is critical to minimize the charger size, charging time, and the amount and cost of electricity drawn from the utility. A detailed analytical model for these topologies is developed, enabling the calculation of power losses and efficiency. Experimental and simulation results of several prototype boost converter converting universal AC input voltage to 400 V DC at 3.4 kW are given to verify the proof of concept, and analytical work reported in this thesis. The results show a power factor greater than 0.99 from 750 W to 3.4 kW, THD less than 5% from half load to full load and a peak efficiency of 98.94% at 265 V input and 1200 W load.

description: Electron instabilities in the Hubbard model with the next nearest neighbor coupling are calculated by exact diagonalization in finite, two-dimensional Betts cells (lattices). A viable spin and charge coherent pairing, signaled by quantum critical points and a negative charge gap region, is found in 8- and 10-site Betts lattices at small and moderate U regions consistent with our exact results in elementary bipartite geometries [Phys. Rev. B 78 (2008) 075431]. The contour isolines for continuous temperature driven-crossover between the Mott-Hubbard insulating and coherent pairing phases are demonstrated. The criteria for smooth and abrupt phase transitions are found for systematic enhancement of coherent pairing by optimization of the next nearest neighbor coupling parameter.

description: Near conformal dynamics is employed in different extensions of the standard model of particle interactions as well as in cosmology. Many of its interesting properties are either conjectured or determined using model computations. We introduce a relevant four dimensional gauge theory template allowing us to investigate such dynamics perturbatively. The gauge theory we consider is quantum chromodynamics with the addition of a meson-like scalar degree of freedom as well as an adjoint Weyl fermion. At the two-loop level, and in the Veneziano limit, we firmly establish the existence of several fixed points of which one is all directions stable in the infrared. An interesting feature of the model is that this fixed point is lost, within the perturbatively trustable regime, by merging with another fixed point when varying the number of quark flavors. We show the emergence of the Miransky scaling and determine its properties. We are also able to determine the walking region of the theory which turns out to be, at large number of colors, about 12% of the conformal window. Furthermore, we determine highly relevant quantities for near conformal dynamics such as the anomalous dimension of the fermion masses.

description: Almost a decade into the twenty-first century, absolute poverty still pervades outside the industrialized world. Helping poor people in poor countries improve their levels of living is on the short list of international policy goals. The air is full of ideas about how poverty should be analyzed and attacked. Although there have been some success stories, particularly in East Asia, the unhappy truth is that anti-poverty programs in developing countries have quite often failed or have had limited success. The reason why is that they did not enable poor economies to generate long-term growth of real per capita income. A useful rule of thumb is that developing and transition economies should sustain at least 2% annual per capita real growth of gross domestic product or GDP. That would stop the gap separating their standards of living from the industrial world's from widening even further, and 3% or more would gradually reduce it. A 2% per capita growth rate can make a big dent in poverty by increasing average income by 22% over 10 years and 49% over 20. In addition, growth can only address poverty concerns if it generates new jobs to keep pace with a rising labor force.

description: We examine labor market integration in east and southeast Asia (ESEA) during the 1980s, focusing on intraregional labor mobility and on the two other main channels of integration: capital mobility and trade. We find evidence that labor market integration increased sharply among ESEA countries in the 1980s, with 9 percent of ESEA's labor force participating, either directly via labor mobility or indirectly via capital mobility or trade, in cross-national labor market transactions in 1991, up from just 5.2 percent in 1980. We also find that trade is the dominant mechanism through which regional labor market integration occurred in the 1980s, with labor migration contributing only modestly to the process.
Idiosyncratic risk and creative destruction in Japan

description: The dramatic rise and fall of the Japanese equity market provides us with a unique opportunity to examine market- and firm-specific risks over different market conditions. Contrary to the U.S. experience, we document a surprising fall in firm-level volatility and turnover in Japanese stocks after the market crash. Accordingly, correlations among individual stocks have increased and the number of stocks needed to achieve a given level of diversification has declined. As a consequence, we suggest that it has become more difficult over the past decade for both investors and managers to separate highquality from low-quality firms, making the Japanese market less efficient. Moreover, changes in firm-level volatilities are positively related to corporate bankruptcies, indicating that improvements in information efficiency occur when regulations on corporate bankruptcies are relaxed. These results suggest that the sharp fall in firm-level volatility during the 1990-1996 period could be due to a lack of corporate restructuring. This is more evident for firms with business group and main bank affiliations, whose firm-level volatility is less dependent on economic conditions than that of firms with no affiliations. Thus, we argue that a lack of "creative destruction" may have led to Japanese market inefficiency and a vicious cycle of capital misallocation.

description: Diabetics must choose how much effort to devote to health care. Technological innovation and product differentiation have lowered the price of diabetic compliance. It is now easier to frequently test blood and to adjust insulin levels. The quality of sugar free food substitutes have greatly improved. New diabetic cohorts should be healthier than previous cohorts. This paper uses the 1976 and 1989 cross sections of the National Health Interview Surveys to study output indicators, such as income and labor force participation, and input indicators, such as diet and weight, of diabetics and non diabetics to evaluate this "convergence" hypothesis.

description: We investigate the one-loop effect of new charged scalar bosons on the Higgs potential at finite temperatures in the supersymmetric standard model with four Higgs doublet chiral superfields as well as a pair of charged singlet chiral superfields. In this model, the mass of the lightest Higgs boson $h$ is determined only by the D-term in the Higgs potential at the tree-level, while the triple Higgs boson coupling for $hhh$ can receive a significant radiative correction due to nondecoupling one-loop contributions of the additional charged scalar bosons. We find that the same nondecoupling mechanism can also contribute to realize stronger first order electroweak phase transition than that in the minimal supersymmetric standard model, which is definitely required for a successful scenario of electroweak baryogenesis. Therefore, this model can be a new candidate for a model in which the baryon asymmetry of the Universe is explained at the electroweak scale.

description: The 110Pd double-beta decay Q-value was measured with the Penning-trap mass spectrometer ISOLTRAP to be Q = 2017.85(64) keV. This value shifted by 14 keV compared to the literature value and is 17 times more precise, resulting in new phase-space factors for the two-neutrino and neutrinoless decay modes. In addition a new set of the relevant matrix elements has been calculated. The expected half-life of the two-neutrino mode was reevaluated as 1.5(6) E20 yr. With its high natural abundance, the new results reveal 110Pd to be an excellent candidate for double-beta decay studies.

Based on the analysis of electron-hole pairing in the extended Falicov-Kimball model, we show that tuning the Coulomb attraction between both species, a continuous crossover between a BCS-like transition of Cooper-type pairs and a Bose-Einstein condensation of preformed tightly-bound excitons might be achieved in a solid-state system. The precursor of this crossover in the normal state might cause the transport anomalies observed in several strongly correlated mixed-valence compounds.

Fast magnetization reversal of nanoclusters in resonator

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: An effective method for ultrafast magnetization reversal of nanoclusters is suggested. The method is based on coupling a nanocluster to a resonant electric circuit. This coupling causes the appearance of a magnetic feedback field acting on the cluster, which drastically shortens the magnetization reversal time. The influence of the resonator properties, nanocluster parameters, and external fields on the magnetization dynamics and reversal time is analyzed. The magnetization reversal time can be made many orders shorter than the natural relaxation time. The reversal is studied for both the cases of a single nanocluster as well as for the system of many nanoclusters interacting through dipole forces.

The process of safer crack use amongst women in Vancouver's downtown eastside
Creators: name: Handlovsky, Ingrid Emilia
Publisher: name: University of British Columbia
Year: 2013

description: Crack cocaine is prevalent in Vancouver’s Downtown Eastside, with evidence suggesting women use more than men. Crack cocaine poses many harms to the body, and women face unique harms due to the gendered use of crack. However, there has been little investigation into how women go about minimizing some of the harms associated with crack. Informed by harm reduction and women’s-centred philosophies, a grounded theory approach was employed to explore the process that women engage in to limit the physical, psychological and interpersonal harms associated with crack use, as well as identify the social, economic and political factors that influence the process of safer use. Data were collected via seven group interviews (n=27) that took place over a three month period with women who were actively using crack cocaine. Data illustrated women’s crack use patterns shifted over time from heavier to more intermittent use, and four central processes that enabled women to practice safer crack use were identified. At the root of these processes was a dedication to care for the self and others. The processes were identified as: establishing a safe physical space, building trusting relationships, learning about safer crack use, and accessing safer use equipment. These strategies were in turn influenced by larger contextual factors including the spatial environment (violence and police activity), economics (living with extreme financial limitations) and politics (the instability of supportive housing and lack of safe places for women). Women demonstrated proficiency to care for themselves and others in the context of crack use, but many changes within the political and health care systems are necessary to facilitate safer practices to improve health outcomes. Firstly, a political agenda that is dedicated to the development of supportive housing is essential for safer use, as is greater access to income assistance. Furthermore, harm reduction programming that focuses on women’s contributions and expertise in the realm of safer use is essential to ongoing development of a supportive community of women. Moreover, the availability of safer use equipment is quintessential for women to apply knowledge regarding safer crack use to minimize some of the harms associated with crack.
Discerning consent on the Gridiron: violence, hazing, and performance enhancing drug ise in Canadian football

description: This thesis explores the disjuncture between Canadian football players' experiences and perceptions of consent in relation to on-field violence, hazing, and performance-enhancing drug use and the textual representations and hand lings of these acts in the Canadian legal system and/or by league review committees. This thesis provides ample evidence that the institutional disciplinary hand lings of these acts of deviance in Canadian football do not align with the perceptions and interests of Canadian football players. In this work, two main theoretical concepts are developed and applied to provide descriptive sociological insight into the legal issue of consent in Canadian football, including tolerable deviance and a legal concept of constraint. The canons of exploratory research are followed in this study, which provide guidelines to follow but no rigid methodological rules. Through the combination of three f existing theory/methods a unique methodological approach is developed that is indeinite, flexible, and creative to aptly explore the complexities of on-field violence, hazing, and performance-enhancing drug use in Canadian football. This approach is not without theory or method but rather, draws on three approaches that can be termed exploratory theory/methods including: Institutional Ethnography, Actor-Network Theory, and Grounded Theory. The data developed and activated in this study include media files, over 40 Canadian legal cases, 81 semi-directed interviews with football players and administrators across Canada, published autobiographies of professional football players, as well as various texts involved in the institutional handling of disciplinary matters in junior, university, and professional football in Canada.
Protection of lysozyme with chitosan using radiant energy vacuum dehydration for control of clostridial necrotic enteritis in broiler chickens
Creators: name: Zhang, Guopeng
Publisher: name: University of British Columbia
Year: 2011

description: The aim of this study was to develop a heat-stable and slow-release lysozyme-based product using radiant energy under vacuum (REV) technology by formulating lysozyme in a chitosan matrix so that the product could be used as a feed additive for more effective control of clostridial necrotic enteritis (NE) in broiler chickens. Lysozyme/chitosan was made into pastes with water at 25-45% solids content. These were dried with REV technology (300 watts microwave power under 4 KPa absolute pressure). Lysozyme retained its full activity during this process. A REV-treated sample produced with a paste containing 25% solids had a Tm of 124.6°C, which was substantially higher than that of spray-dried lysozyme (101.7°C). Thermal destruction curves constructed over a range of 100-130°C were used to determine D- and z-values of lysozyme and the REV-treated samples. REV products were consistently more heat-resistant than native lysozyme powder. A small scale feed pelleting study showed significantly better recovery of lysozyme in the chitosan protected REV product(P<0.05). The total porosity and pore size distribution of the REV products were analyzed with an Hg porosimeter. In the REV-treated samples, more than 80% of pore volume represented pore sizes ≥ 300 μm in radius, which were larger than those of native lysozyme powder. Surface structure analysis by scanning electron microscopy suggested the REV samples contained lysozyme evenly distributed inside the chitosan matrix. The REV samples released lysozyme more slowly in aqueous solution than lysozyme powder alone in water. A cage study was conducted to demonstrate the effect of Entegard™REV, the REV-treated lysozyme antimicrobial mixture, on the performance of broiler chickens and necrotic enteritis disease reduction of birds that were challenged with Eimeria maxima and Clostridium perfringens. Entegard™REV included in feed at 200 g/metric ton (MT) was very effective in reducing the negative health effects in the birds following NE challenge, and its ability to control the disease was not statistically different from a commonly used antibiotic growth promotant, bacitracin methylene disalicylate (BMD), at 55 g/MT.

description: This paper reviews the experience of three developing countries -- Chile, Colombia and Malaysia. After having opened up their capital accounts, these countries decided to fine-tune their integration into international financial markets (via the reintroduction of capital controls) in order to deal with the 1990s surge in private capital inflows, particularly short-term portfolio inflows. The next section of this paper looks at the dynamics of capital flows into developing countries, and presents some contrasting experiences of Latin America and East Asia. The nest analyses the nature and effects of regulations on capital inflows in these three countries during the 1990s; in particular their effects on the magnitude and composition of capital flows, on the macroeconomic policy space that the authorities enjoyed under these circumstances, and on asset prices.

This is a typical member of the genus Johnsonomyia, with the exception that the tegmen has prominent, moderately sclerotized edges apicolaterally (Parnell 1971: fig. 8), not unlike those found in many Gynapteromyia and some Haplusia. I have seen an unnamed Johnsonomyia from Costa Rica with a similar tegmen, but there it is completely membranous, which is another unusual condition for this genus. The tarsi of J. fusca are lighter than the more proximal leg segments.

The task I have been assigned is an intellectually challenging one: does the growing globalization of the world economy and the presumed growth then in interdependence promise to constrain national sovereignty; and, does it equally threaten to compromise democratic accountability within nation states?"

description: Bibliography: p. 231-263
description: Canadian policy on asylum seekers is accepted by Canadians as gracious, appropriate, and more than fair. Also, this policy is believed to be free of discrimination. These beliefs construct the Canadian master narrative of a country welcome and open to all. This study investigates the extent the master narrative coincides with refugee policy and practice. Critical discourse is utilized to analyze the Immigration and Refugee Protection Act (IRPA). Disjuncture between Canada' s master narrative and policy is revealed. Semistructured interviews with East African asylum seekers were conducted to explore Canada' s master narrative as reflected in practice. Perceived discrimination of the claimant was investigated, with a focus on the Immigration and Refugee Board hearing. Perceived racial and gender discrimination was low. It is revealed that claimants struggle with reconciling their situation(s) due to the power differential between them as individual refugee claimants and the Canadian state, as solidified in the IRPA.

description: While it is well-known that the electron-electron (\emph{ee}) interaction cannot affect the resistivity of a Galilean-invariant Fermi liquid (FL), the reverse statement is not necessarily true: the resistivity of a non-Galilean-invariant FL does not necessarily follow a T^2 behavior. The T^2 behavior is guaranteed only if Umklapp processes are allowed; however, if the Fermi surface (FS) is small or the electron-electron interaction is of a very long range, Umklapps are suppressed. In this case, a T^2 term can result only from a combined--but distinct from quantum-interference corrections-- effect of the electron-impurity and \emph{ee} interactions. Whether the T^2 term is present depends on 1) dimensionality (two dimensions (2D) vs three dimensions (3D)), 2) topology (simply- vs multiply-connected), and 3) shape (convex vs concave) of the FS. In particular, the T^2 term is absent for any quadratic (but not necessarily isotropic) spectrum both in 2D and 3D. The T^2 term is also absent for a convex and simply-connected but otherwise arbitrarily anisotropic FS in 2D. The origin of this nullification is approximate integrability of the electron motion on a 2D FS, where the energy and momentum conservation laws do not allow for current relaxation to leading --second--order in T/E_F (E_F is the Fermi energy). If the T^2 term is nullified by the conservation law, the first non-zero term behaves as T^4. The same applies to a quantum-critical metal in the vicinity of a Pomeranchuk instability, with a proviso that the leading (first non-zero) term in the resistivity scales as T^{\frac{D+2}{3}} (T^{\frac{D+8}{3}}). We discuss a number of situations when integrability is weakly broken, e.g., by inter-plane hopping in a quasi-2D metal or by warping of the FS as in the surface states of Bi_2Te_3 family of topological insulators.

Stylized Facts and Policy Alternatives

Subjects: Economics

description: The main objective of this book has been to explain why so many parts of the developing world have failed to generate stable rates of growth in per capita incomes, and to offer policy alternatives for them to correct this outcome. The failure of growth was particularly widespread during the quarter of century or so after a series of adverse shocks beginning in the late 1970s. This period also coincided with a major shift in development policies toward an emphasis on market liberalization and a retreat from state intervention. History has not been kind to the mainstream interpretation of economic development and the policies associated with it.
An analysis of injury definitions and risk of subsequent injury in Cirque du Soleil performers
Creators: name: Hamilton, Gavin
Publisher: name: Kinesiology
Year: 2009

description: Bibligoraphy: p. 121-132
description: This study explored how different definitions of injury (i.e., medical attention versus time loss) affect 1) injury rates, 2) consequences of injury, 3) risk factor analysis and 4) subsequent injury risk. Cirque du Soleil performers (n=1281) were followed for a total of 812,008 performances over a period of 49 months (2004 to 2008). Cirque therapists used an electronic database as their charting procedure for injuries and treatments. Results showed that the choice of injury definition affected estimates of the injury rate, the consequence of injury and the assessment of statistical significance for risk factors. Using survival analysis techniques and conditioning on the individual, the risk of an index injury was similar to the risk of a subsequent injury (HR=0.97, 95% CI; 0.88 to 1.08), no matter the injury definition. These results suggest that individuals have a fixed ratio for subsequent injuries and an injury may not increase the risk of subsequent injuries.
Molecular Constraints on Synaptic Tagging and Maintenance of Long-Term Potentiation: A Predictive Model

description: Protein synthesis-dependent, late long-term potentiation (LTP) and depression (LTD) at glutamatergic hippocampal synapses are well characterized examples of long-term synaptic plasticity. Persistent increased activity of the enzyme protein kinase M (PKM) is thought essential for maintaining LTP. Additional spatial and temporal features that govern LTP and LTD induction are embodied in the synaptic tagging and capture (STC) and cross capture hypotheses. Only synapses that have been "tagged" by an stimulus sufficient for LTP and learning can "capture" PKM. A model was developed to simulate the dynamics of key molecules required for LTP and LTD. The model concisely represents relationships between tagging, capture, LTD, and LTP maintenance. The model successfully simulated LTP maintained by persistent synaptic PKM, STC, LTD, and cross capture, and makes testable predictions concerning the dynamics of PKM. The maintenance of LTP, and consequently of at least some forms of long-term memory, is predicted to require continual positive feedback in which PKM enhances its own synthesis only at potentiated synapses. This feedback underlies bistability in the activity of PKM. Second, cross capture requires the induction of LTD to induce dendritic PKM synthesis, although this may require tagging of a nearby synapse for LTP. The model also simulates the effects of PKM inhibition, and makes additional predictions for the dynamics of CaM kinases. Experiments testing the above predictions would significantly advance the understanding of memory maintenance.

Growth Rates, Economic Structures, and Energy Use

Publisher: name: Columbia University
Year: 2009
Subjects: Economics

description: This chapter is about the growth and development performance of non-industrialized countries in the latter part of the twentieth century, in particular the "great divergence" of their growth rates of per capita GDP from those of the industrial world since around 1980 until the early part of the 2000s that was illustrated in Chapter 2. The goal is to explore the factors underlying observed patterns of growth, and trace out plausible lines of causation for their diversity. The analysis follows Kuznets (1966) in attempting to organize the data in such a way as to highlight salient relationships, or the lack thereof, among key economic variables.
Non-Thermal Dark Matter Mimicking An Additional Neutrino Species In The Early Universe

description: The South Pole Telescope (SPT), Atacama Cosmology Telescope (ACT), and Wilkinson Microwave Anisotropy Probe (WMAP) have each reported measurements of the cosmic microwave background's (CMB) angular power spectrum which favor the existence of roughly one additional neutrino species, in addition to the three contained in the standard model of particle physics. Neutrinos influence the CMB by contributing to the radiation density, which alters the expansion rate of the universe during the epoch leading up to recombination. In this paper, we consider an alternative possibility that the excess kinetic energy implied by these measurements was possessed by dark matter particles that were produced through a non-thermal mechanism, such as late-time decays. In particular, we find that if a small fraction (<1%) of the dark matter in the universe today were produced through the decays of a heavy and relatively long-lived state, the expansion history of the universe can be indistinguishable from that predicted in the standard cosmological model with an additional neutrino. Furthermore, if these decays take place after the completion of big bang nucleosynthesis, this scenario can avoid tension with the value of three neutrino species preferred by measurements of the light element abundances.

Modeling Soviet Agriculture for Assessing Commanding Economy Policies

Subjects: Economics

description: A fixed effect production function model is adopted and estimated in this paper for evaluating the agricultural policies of the Soviet planners in Russia (formerly RSFSR) and Kazakhstan from 1953 to 1980. In particular, the functional form allows the variance of output to increase or decrease as one input is increased. Our estimates suggest the following assessment of the Soviet planners' agricultural policies during the command economy days: First, the extension of farming in Kazakhstan with generally inferior soils and climate resulted in lower crop levels (with identical input applications). Second, the massive inflow of capital resources and sharp rise in fertilizer use in agriculture during the Brezhnev years (1964-1982) did not contribute significantly to crop levels in the two republics. Finally, the extension of the cultivated area into marginal lands generally, and of fertilizer use in wrong mix and form contributed to the instability of agricultural output. In conclusion, we emphasize the need for specifying and estimating appropriate models for evaluating Soviet agricultural policies especially because farm-level data are rapidly becoming available in the republics of the former Soviet Union.

description: We provide manganese abundances (corrected for the effect of the hyperfine structure) for a large number of stars in the dwarf spheroidal galaxies Sculptor and Fornax, and for a smaller number in the Carina and Sextans dSph galaxies. Abundances had already been determined for a number of other elements in these galaxies, including alpha and iron-peak ones, which allowed us to build [Mn/Fe] and [Mn/alpha] versus [Fe/H] diagrams. The Mn abundances imply sub-solar [Mn/Fe] ratios for the stars in all four galaxies examined. In Sculptor, [Mn/Fe] stays roughly constant between [Fe/H]\sim -1.8 and -1.4 and decreases at higher iron abundance. In Fornax, [Mn/Fe] does not vary in any significant way with [Fe/H]. The relation between [Mn/alpha] and [Fe/H] for the dSph galaxies is clearly systematically offset from that for the Milky Way, which reflects the different star formation histories of the respective galaxies. The [Mn/alpha] behavior can be interpreted as a result of the metal-dependent Mn yields of type II and type Ia supernovae. We also computed chemical evolution models for star formation histories matching those determined empirically for Sculptor, Fornax, and Carina, and for the Mn yields of SNe Ia, which were assumed to be either constant or variable with metallicity. The observed [Mn/Fe] versus [Fe/H] relation in Sculptor, Fornax, and Carina can be reproduced only by the chemical evolution models that include a metallicity-dependent Mn yield from the SNe Ia.
