description: The apparent metal-insulator transition is observed in a high quality two-dimensional electron system (2DES) in the strained Si quantum well of a Si/Si_{1-x}Ge_x heterostructure with mobility μ=1.9 x 10^5 cm^2/Vs at density n=1.45 x 10^{11} cm^{-2}. The critical density, at which the thermal coefficient of low T resistivity changes sign, is ~ 0.32 x 10^{11} cm^{-2}, so far the lowest observed in the Si 2D systems. In-plane magnetoresistance study was carried out in the higher density range where the 2DES shows the metallic-like behavior. It is observed that the in-plane magnetoresistance first increases as ~ B_{ip}^2 and then saturates to a finite value ρ(B_c) for B_{ip} > B_c. The full spin-polarization field B_c decreases monotonically with n but appears to saturate to a finite value as n approaches zero. Furthermore, ρ(B_c)/ρ(0) ~ 1.8 for all the densities ranging from 0.35 x 10^{11} to 1.45 x 10^{11} cm^{-2} and, when plotted versus B_{ip}/B_c, collapses onto a single curve.
Renegotiating the past : contemporary tradition and identity of the Comox First Nation
Creators: name: Everson, Andrew Frank
Publisher: name: University of British Columbia
Year: 2009

description: This thesis investigates expressions of tradition currently being brought forth by members of the Comox First Nation as markers of their identity. A history of massive depopulation and territorial movement, combined with extensive intermarriage outside of the community, has left the Comox peoples with varying degrees of traditional and cultural knowledge. Bound on all sides by the Central Coast Salish, the Nuu-chah-nulth, and the Kwakwaka'wakw, rights to their traditions are restricted to certain families in the community. This limitability of tradition has led the Comox peoples to bring forward and reinvent traditions that are accessible to all members of the First Nation. This study moves away from the tendency of anthropological investigations to concentrate work amongst perceived cultural cores, and instead looks directly at dilemmas and resolutions of identity that are prevalent within border communities.

intercropping

description: Pea (Pisum sativum L.) is a valuable crop species containing around 20% crude protein in the seed. Cultivated as a pure crop, pea is prone to lodging and susceptible to biotic and abiotic stress. This is especially the case for the taller cultivars often used for forage. This leads to diminished crop performance and inferior crop quality. This practice note provides insight into intercropping systems of pea and cereals as developed and used in Switzerland. This cropping system was developed over years in an iterative process in cooperation with farmers using farm-based experiments.

description: Using deep learning to analyze mechanical stress distributions has been gaining interest with the demand for fast stress analysis methods. Deep learning approaches have achieved excellent outcomes when utilized to speed up stress computation and learn the physics without prior knowledge of underlying equations. However, most studies restrict the variation of geometry or boundary conditions, making these methods difficult to be generalized to unseen configurations. We propose a conditional generative adversarial network (cGAN) model for predicting 2D von Mises stress distributions in solid structures. The cGAN learns to generate stress distributions conditioned by geometries, load, and boundary conditions through a two-player minimax game between two neural networks with no prior knowledge. By evaluating the generative network on two stress distribution datasets under multiple metrics, we demonstrate that our model can predict more accurate high-resolution stress distributions than a baseline convolutional neural network model, given various and complex cases of geometry, load and boundary conditions.

description: The performance of over 500 North Dakota farms, 2001-2003, is summarized using 16 financial measures. Farms are categorized by geographic region, farm type, farm size, gross cash sales, farm tenure, net farm income, debt-to-asset, and age of farmer to analyze relationships between financial performance and farm characteristics. Farm financial trends for the 1994-2003 period are also presented. Financial performance in 2003 was the highest of the 1994-2003 period because of a good wheat and barley crop, strong crop prices, and improved livestock profit. Median net farm income was $49,181 in 2003, $38,079 in 2002, and $27,729 in 2001. Financial performance for the 1994-2003 period was poorest in 1997 and 1998 when over one-half of farms could not make scheduled term debt payments with the year's income. A strong improvement occurred in 2000 and 1999 because of extraordinary government and crop insurance payments, record yields for some crops, and improved beef cattle prices. All 16 financial performance measures declined in 2001, except interest expense ratio, because of lower government subsidies, higher costs, and continued low commodity prices. Performance improved in 2002, except for the west region and livestock farms, because of strong crop prices and lower costs.
Gamma Rays from Heavy Neutralino Dark Matter

description: We consider the gamma-ray spectrum from neutralino dark matter annihilations and show that internal bremsstrahlung of W pair final states gives a previously neglected source of photons at energies near the mass of the neutralino. For masses larger than about 1 TeV, and for present day detector resolutions, this results in a characteristic signal that may dominate not only over the continuous spectrum from W fragmentation, but also over the γ-γand γ-Z line signals which are known to give large rates for heavy neutralinos. Observational prospects thus seem promising.

Supernovae Ia observations in the Lemaitre--Tolman model

description: The aim of this paper is to check if the models with realistic inhomogeneous matter distribution and without cosmological constant can explain the dimming of the supernovae in such a way that it can be interpreted as an acceleration of the Universe. Employing the simplest inhomogeneous model, i.e. Lemaitre-Tolman model, this paper examines the impact of inhomogeneous matter distribution on light propagation. These analyses show that realistic matter fluctuations on small scales induce brightness fluctuations in the residual Hubble diagram of amplitude around 0.15 mag, and thus can mimic acceleration. However, it is different on large scales. All these brightness fluctuations decrease with distance and hence cannot explain the dimmining of supernovae for high redshift without without invoking the cosmological constant.This paper concludes that models with realistic matter distribution (i.e. where variation of the density contrast is similar to what is observed in the local Universe) cannot explain the observed dimming of supernovae without the cosmological constant.

description: This report evaluates the U.S. and world wheat markets for the 2004-2013 period using the Global Wheat Policy Simulation Model. This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change. Both the U.S. and world wheat economies are predicted to improve for the next nine years. World demand for both common and durum wheat are expected to grow faster than world production, resulting in gradual increases in prices of the wheat varieties. However, the higher price levels experienced in 2002 and 2003 due to weather conditions will not be maintained in the short term. World trade volumes of both classes of wheat are expected to expand, but trade volume of durum wheat may grow faster than that of common wheat.

description: We advance binational link-tracing sampling design, an innovative data collection methodology for sampling from transnational social fields, i.e., transnational networks embedding migrants and non-migrants. This paper shows the practical challenges of such a design, the representativeness of the samples and the qualities of the resulted networks. We performed 303 face-to-face structured interviews on sociodemographic variables, migration trajectories and personal networks of people living in a Romanian migration sending community (Dâmboviţa) and in a migration receiving Spanish town (Castellón), simultaneously in both sites. Inter-connecting the personal networks, we built a multi-layered complex network structure embedding 4,855 nominated people, 5,477 directed ties (nominations) and 2,540 edges. Results indicate that the participants' unique identification is a particularly difficult challenge, the representativeness of the data is not optimal (homophily on observed attributes was detected in the nomination patterns), and the relational and attribute data allow to explore the social organization of the Romanian migrant enclave in Castellón, as well as its connectivity to other places. Furthermore, we provide methodological suggestions for improving link-tracing sampling from transnational networks of migration. Our research contributes to the emerging efforts of applying social network analysis to the study of international migration.

Remarks.
Freyella giardi was first proposed by Koehler (1907) and described in detail later by the same author (Koehler 1908). As a six-armed species, Koehler (1908) remarked upon its affinity to F. sexradiata but did not compare it with F. tuberculata. According to the original description and examination of the syntypes, this species has inferomarginal plates and lateral spines generally corresponding to every adambulacral plate beyond genital area. Based on this character and many other characters that F. giardi shared with F. tuberculata as discussed above, we reassign this species as Freyastera giardi comb. nov.

description: The Russian establishment- politicians, agricultural officials, corporate farm managers, the media- firmly believe that inadequate access to credit is one of the major factors constraining the growth of the agricultural sector. In technical terms, they in effect claim that Russian agriculture faces credit rationing. In this article, we apply discrete regression analysis to study the determinants of access to credit for corporate farms, without addressing the issue of whether or not the actual borrowing is sufficient for the farms' needs. Our analysis shows that factors reflecting economic efficiency are the main determinants of access to credit. On the other hand, asset endowments, such as land and capital stock, have a very weak effect on the ability to borrow. Our findings caution against generalizing the conventional financial patterns of market economies to transition countries.

description: Conformance checking is a set of process mining functions that compare process instances with a given process model. It identifies deviations between the process instances' actual behaviour ("as-is") and its modelled behaviour ("to-be"). Especially in the context of analyzing compliance in organizations, it is currently gaining momentum -- e.g. for auditors. Researchers have proposed a variety of conformance checking techniques that are geared towards certain process model notations or specific applications such as process model evaluation. This article reviews a set of conformance checking techniques described in 37 scholarly publications. It classifies the techniques along the dimensions "modelling language", "algorithm type", "quality metric", and "perspective" using a concept matrix so that the techniques can be better accessed by practitioners and researchers. The matrix highlights the dimensions where extant research concentrates and where blind spots exist. For instance, process miners use declarative process modelling languages often, but applications in conformance checking are rare. Likewise, process mining can investigate process roles or process metrics such as duration, but conformance checking techniques narrow on analyzing control-flow. Future research may construct techniques that support these neglected approaches to conformance checking.

description: The consumer perception of the relation between food and health is increased his importance. This situation generates business opportunities, when his effect is positive (for example "functional food"), or limitations or reductions in the markets (for example "food with risk perception"). This paper trait to present the relation between consumer perception of 1) intrinsic and extrinsic product attributes and 2) the influenced aspects on the label valuation on the product confidence and consumption reduction, in one market with risk perception (beef). The data has been obtained in two European Regions: Friuli-Venezia-Giulia in Italy and Navarra in Spain, differentiated in commercial aspects related fundamentally with the product differentiation. The principal information is based on a home consumer survey designed ad hoc. The structural equation model to multi-group analysis has been the main methodology selected to explain the data. The results showed similarities in different aspects on consumer behaviour independently of the market distance, and the influence of the commercial aspects in the valuations and consumer decisions. So that, the market differentiated (Spain-region) is best protected to the alternative type of scares.

Resumes and choices : analyzing the discourses of a decision-making activity
Creators: name: Semenova, Daria
Publisher: name: University of British Columbia
Year: 2009

description: Available research on the resume genre assumes that the communicative purpose of the resume is promotional and persuasive. While there is ample evidence that this premise is true for North American resumes, the research on resumes across cultures is limited (Popken, 1993). Yet in light of the current trends of globalization and migration of skilled workers, the resume becomes an important genre to study cross-culturally. Research Question 1 explores the communicative purposes of the resume genre to see whether they are culturally universal. The findings here add to the limited research base by investigating the resume-writing practices of North America, Japan, and Russia. Research Question 2 is linked to Research Question 1 as it explores the issue of genre analysis: How can choice as revealed in insider accounts link genre, communicative purposes, and the social and cultural context of a genre? The study looks at the resume as a process and uses Systemic Functional Linguistics to examine language as a system of choice from which certain options are selected to achieve the desired outcomes (Halliday, 1994; Hasan, 1996). The thesis further draws on Mohan's (2000) look at language as choices based on reasons which are rooted in socioculturally grounded values and beliefs. Taking this decision-making perspective, the study examines the "insider accounts" (Hammersley & Atkinson, 1983) of 12 groups of participants through the discourse of the resume-editing sessions and interviews. It looks at how people make decisions about the genre while writing a resume and talking about it. The participants' explanations of the reasons behind their choices are examined to illuminate the sociocultural aspects of the resume and interpret its communicative purpose across the three cultures. The findings show that while the broad purpose of the resume may be the same across cultures, it can be expressed differently through resume layout, content, and language. The reasons behind each of these choices are based on cultural beliefs which can be made explicit by examining the discourse of people who are engaged in talking about their choices while constructing a genre.

description: We study the optimal way to estimate the quantum expectation value of a physical observable when a finite number of copies of a quantum pure state are presented. The optimal estimation is determined by minimizing the squared error averaged over all pure states distributed in a unitary invariant way. We find that the optimal estimation is "biased", though the optimal measurement is given by successive projective measurements of the observable. The optimal estimate is not the sample average of observed data, but the arithmetic average of observed and "default nonobserved" data, with the latter consisting of all eigenvalues of the observable.

description: This work is devoted to the analysis of the different labor market participation regimes of Chinese farm households. Using household data over the period 1986-2000 from the province Zhejiang, we apply a multinomial logit model to empirically examine household, farm, and regional characteristics affecting the probability that farmers employ one of four alternative labor market regimes. Results suggest that labor market decisions are significantly related to several personal, farm, and village attitudes. In addition, we find the more market oriented policy reforms at the end of the 1980s stipulated that households participate in labor markets while the more anti-market reforms during the 1990s led to the opposite and encouraged autarky.

description: The objective of this paper is to provide an analysis of the sustainability of irrigated agriculture in Italy in the context of CAP reform and Water Framework Directive. The work combines scenario analysis, multicriteria mathematical programming simulation models and economic, social and environmental indicators. Five irrigated farming systems were considered: cereals, rice, fruit, vegetables and citrus. The results show the diversity of Italian irrigated farming systems and the trade-off between socio-economic and environmental performance. This highlights the need for a differentiated application of the Water Framework Directive, balancing water conservation and rural development objectives.

description: We present high resolution spectroscopy of the common proper motion system FH Leo (components HD 96273 and BD+07 2411B), which has been classified as a novalike variable due to an outburst observed by Hipparcos, and we present and review the available photometry. We show from our spectra that neither star can possibly be a cataclysmic variable, instead they are perfectly normal late-F and early-G stars. We measured their radial velocities and derived the atmospheric fundamental parameters, abundances of several elements including Fe, Ni, Cr, Co, V, Sc, Ti, Ca and Mg, and we derive the age of the system. From our analysis we conclude that the stars do indeed constitute a physical binary. However, the observed outburst cannot be readily explained. We examine several explanations, including pollution with scattered light from Jupiter, binarity, microlensing, background supernovae, interaction with unseen companions and planetary engulfment. While no explanation is fully satisfactory, the scattered light and star-planet interaction scenarios emerge as the least unlikely ones, and we give suggestions for further study.

description: During Parker Solar Probe's first two orbits there are widespread observations of rapid magnetic field reversals known as switchbacks. These switchbacks are extensively found in the near-Sun solar wind, appear to occur in patches, and have possible links to various phenomena such as magnetic reconnection near the solar surface. As switchbacks are associated with faster plasma flows, we questioned whether they are hotter than the background plasma and whether the microphysics inside a switchback is different to its surroundings. We have studied the reduced distribution functions from the Solar Probe Cup instrument and considered time periods with markedly large angular deflections, to compare parallel temperatures inside and outside switchbacks. We have shown that the reduced distribution functions inside switchbacks are consistent with a rigid phase space rotation of the background plasma. As such, we conclude that the proton core parallel temperature is the same inside and outside of switchbacks, implying that a T-V relationship does not hold for the proton core parallel temperature inside magnetic field switchbacks. We further conclude that switchbacks are consistent with Alfvénic pulses travelling along open magnetic field lines. The origin of these pulses, however, remains unknown. We also found that there is no obvious link between radial Poynting flux and kinetic energy enhancements suggesting that the radial Poynting flux is not important for the dynamics of switchbacks.

Cluster Masses from CMB and Galaxy Weak Lensing

description: Gravitational lensing can be used to directly constrain the projected density profile of galaxy clusters. We discuss possible future constraints from lensing of the CMB temperature and polarization, and compare to results from galaxy weak lensing. We model the moving lens and kinetic SZ signals that confuse the temperature CMB lensing when cluster velocities and angular momenta are unknown, and show how they degrade parameter constraints. The CMB polarization cluster lensing signal is ~1 micro-Kelvin for massive clusters and challenging to detect; however it should be significantly cleaner than the temperature signal and may provide the most robust constraints at low noise levels. Galaxy lensing is likely to be much better for constraining cluster masses at low redshift, but for clusters at redshift z >~ 1 future CMB lensing observations may be able to do better.

description: This paper compares two ways of financing the combating of Foot and Mouth Disease (FMD) in the EU and uses a simulation model to determine the welfare and production implications of the two systems. The two systems analysed are (i) financing by the tax payers, resembling the system currently in place, and (ii) a compulsory insurance scheme where all costs are converted into regionally differentiated insurance premiums that are paid by the producers. The analysis indicates that welfare gains may be realised by shifting from the former to the latter financing system.

description: For studies of galaxy formation and evolution, one of the major benefits of the James Webb Space Telescope is that space-based IFUs like those on its NIRSpec and MIRI instruments will enable spatially resolved spectroscopy of distant galaxies, including spectroscopy at the scale of individual star-forming regions in galaxies that have been gravitationally lensed. In the meantime, there is only a very small subset of lensed sources where work like this is possible even with the Hubble Space Telescope's Wide Field Camera 3 infrared channel grisms. We examine two of these sources, SDSS J1723+3411 and SDSS J2340+2947, using HST WFC3/IR grism data and supporting spatially-unresolved spectroscopy from several ground-based instruments to explore the size of spatial variations in observed strong emission line ratios like O32, R23, which are sensitive to ionization parameter and metallicity, and the Balmer decrement as an indicator of reddening. We find significant spatial variation in the reddening and the reddening-corrected O32 and R23 values which correspond to spreads of a few tenths of a dex in ionization parameter and metallicity. We also find clear evidence of a negative radial gradient in star formation in SDSS J2340+2947 and tentative evidence of one in SDSS J1723+3411, though its star formation is quite asymmetric. Finally, we find that reddening can vary enough spatially to make spatially-resolved reddening corrections necessary in order to characterize gradients in line ratios and the physical conditions inferred from them, necessitating the use of space-based IFUs for future work on larger, more statistically robust samples.

Changes in Competitiveness of Farm Sector in Candidate Countries Prior to the EU Accession: The Case of Poland

description: Prior to the EU accession Polish agricultural sector was experiencing serious structural problems. Not surprisingly Polish agricultural negotiations with EU were the toughest. Polish officials wanted to convince domestic rural electorate that the farms will operate on the competitive basis in enlarged EU. This paper investigates, however, how the competitiveness has been evolving yet prior to the accession, given the strong pressures within which it had to operate. We asked if Polish farms were responsive to this pressure - that is whether they were able to increase their productivity sufficiently to counter negative forces at work and maintain their competitiveness. The research showed a gloomy picture of declining farm productivity together with deteriorating relative agricultural prices over 1996-2000 which revealed falling competitiveness in the sector. This can partially explain why the rural electorate in Poland was very much against the EU accession till the very end. The Polish experience can be useful for the next EU candidate countries.

description: Agricultural support payments in the EU are increasingly connected to compliance with environmental standards, through cross-compliance and "Good Farming Practice"-conditions. In this paper, this relatively new approach is analysed regarding targeting, compatibility with legal procedures, and effects on income and production. Compliance with standards is reinforced by more systematic controls and reductions of support payments. As farms are affected by such sanctions to a different extent, risk-analysis for selection of farms to be controlled is a crucial element of implementation. The real environmental impacts have to be considered, especially if indirect control indicators are applied. Furthermore, technical assistance and audits have to be promoted for the implementation of environmental standards.

Detecting Exoplanets Using Eclipsing Binaries as Natural Starshades

description: We investigate directly imaging exoplanets around eclipsing binaries, using the eclipse as a natural tool for dimming the binary and thus increasing the planet to star brightness contrast. At eclipse, the binary becomes point-like, making coronagraphy possible. We select binaries where the planet-star contrast would be boosted by $>10\times$ during eclipse, making it possible to detect a planet that is $\gtrsim10\times$ fainter or in a star system that is $\sim2$-$3\times$ more massive than otherwise. Our approach will yield insights into planet occurrence rates around binaries versus individual stars. We consider both self-luminous (SL) and reflected light (RL) planets. In the SL case, we select binaries whose age is young enough so that an orbiting SL planet would remain luminous; in U Cep and AC Sct, respectively, our method is sensitive to SL planets of $\sim$4.5$M_J$ and $\sim$9$M_J$ with current ground- or near-future space-based instruments, and $\sim$1.5$M_J$ and $\sim$6$M_J$ with future ground-based observatories. In the RL case, there are three nearby ($\lesssim50$ pc) systems -- V1412 Aql, RR Cae, RT Pic -- around which a Jupiter-like planet at a planet-star separation of $\gtrsim20$ mas might be imaged with future ground- and space-based coronagraphs. A Venus-like planet at the same distance might be detectable around RR Cae and RT Pic. A habitable Earth-like planet represents a challenge; while the planet-star contrast at eclipse and planet flux are accessible with a 6-8m space telescope, the planet-star separation is 1/3 - 1/4 of the angular separation limit of modern coronagraphy.

With the additional constraint from the world average of the B_s^0$lifetime measurements using semileptonic decays, we find tau (B_s^0)= 1.39 +/- 0.06 ~ps and Delta Gamma/Γ= 0.25^{+0.14}_{-0.15}. For the ratio of the B_s^0 and B^0 lifetimes we obtain tau(B_s^0)/tau(B^0)} = 0.91 +/- 0.09 (stat) +/- 0.003 (syst).

description: Various studies show that agricultural cooperatives behave differently than their investor-owned counterparts. One explanation may be that the internal decision making process differs in these two governance structures. A model is developed to explore how endogenous screening rules affect efficient organizational choices and industrial structures. It is shown that screening level choice may outweigh architecture choice and that screening rules are strategic substitutes. Conditions are derived under which cooperatives are efficient organizational forms. It is also shown that competition may increase the attractiveness of investor-owned firms and circumstances are determined in which cooperatives and investor owned firms coexist in equilibrium.
