description: A new model for risk management in agriculture is described in the paper. The risk model is constructed as a context dependent process, which includes four main phases. The model is aimed at agricultural advisors, who wish to facilitate and disseminate risk management to farmers. It is developed and tested by an action research approach in an attempt to make risk management more applicable on family farms. Our obtained experiences indicate that farmers don't apply probabilistic thinking and other concepts according to formal decision theory.

description: We demonstrate that chiral hinge modes naturally emerge in insulating crystals undergoing a slow cyclic evolution that changes the Chern-Simons axion angle $θ$ by $2π$. This happens when the surface (not just the bulk) returns to its initial state at the end of the cycle, in which case it must pass through a metallic state to dispose of the excess quantum of surface anomalous Hall conductivity pumped from the bulk. If two adjacent surfaces become metallic at different points along the cycle, there is an interval in which they are in topologically distinct insulating states, with chiral modes propagating along the connecting hinge. We illustrate these ideas for a tight-binding model consisting of coupled layers of the Haldane model with alternating parameters. The surface topology is determined in a slab geometry using two different markers, surface anomalous Hall conductivity and surface-localized charge pumping (flow of surface-localized Wannier bands), and we find that both correctly predict the appearance of gapless hinge modes in a rod geometry. When viewing the axion pump as a four-dimensional (4D) crystal with one synthetic dimension, the hinge modes trace Fermi arcs in the Brillouin zone of the 2D hinge connecting a pair of 3D surfaces of the 4D crystal.

description: In the first part of this article, we consider a Groebner basis of the differential ideal {x_1^2} with respect to "the" weighted lexicographical monomial order and show that its computation is related with an identity involving the partitions that appear in the first Rogers-Ramanujan identity. We then prove that a Grobener basis of this ideal is not differentially finite in contrary with the case of "the" weighted reverse lexicographical order. In the second part, we give a simple and direct proof of a theorem of Nguyen Duc Tam about the Groaner basis of the differential ideal {x_1y_1}; we then obtain identities involving partitions with 2 colors.

description: This paper separates market power and efficiency effects of concentration in a sample of 255 U.S. manufacturing industries and computes welfare changes from rises in concentration. The empirical findings reveal that in nearly two-third of the cases, consumers lose as efficiency gains are generally pocketed by the industries. From an aggregate welfare standpoint, concentration is found to be beneficial in nearly 70% of the cases, mostly for low and moderate levels of concentration being particularly against the public interest in highly concentrated markets. Overall, the results support the existing U.S. Federal Trade Commission guidelines for approval of mergers.
Dark Matter and the Baryon Asymmetry

description: We present a mechanism to generate the baryon asymmetry of the Universe which preserves the net baryon number created in the Big Bang. If dark matter particles carry baryon number $B_X$, and $σ^{\rm annih}_{\bar{X}} < σ^{\rm annih}_{X} $, the $\bar{X}$'s freeze out at a higher temperature and have a larger relic density than $X$'s. If $m_X \lsi 4.5 B_X $GeV and the annihilation cross sections differ by $\mathcal{O}$(10%) or more, this type of scenario naturally explains the observed $Ω_{DM} \approx 5 Ω_b$. Two concrete examples are given, one of which can be excluded on observational grounds.
Focal distraction : spatial shifts of attention are not required for contingent capture
Creators: name: Zuvic, Samantha Marija
Publisher: name: University of British Columbia
Year: 2009

description: Contingent capture occurs when distractors that share distinguishing characteristics with a target capture attention and slow down target identification. Conventionally, this slowdown has been attributed to the time wasted by an inappropriate attentional shift to the location of a distractor. To examine this account, we obviated the spatial shift by presenting distractors at fixation, and measured contingent capture both directly by measuring response times and indirectly by estimating the duration for which the target remains vulnerable to backward masking. Contingent capture invariably occurred when a salient distractor was presented within about 600 ms before the target. Because spatial shifts were ruled out using our procedure, the conventional account is insufficient. We augment that account with a two-stage model in which stimuli must pass an input filter tuned to the target's distinguishing characteristic before gaining access to a high-level stage which is unavailable for targets while distractors are being processed.

description: We investigate the discrepancy between oxygen abundance estimations for narrow-line regions (NLRs) of Active Galactic Nuclei (AGNs) type Seyfert 2 derived by using direct estimations of the electron temperature (Te-method) and those derived by using photoionization models. In view of this, observational emission-line ratios in the optical range (3000 < λ(Å) < 7000) of Seyfert 2 nuclei compiled from the literature were reproduced by detailed photoionization models built with the Cloudy code. We find that the derived discrepancies are mainly due to the inappropriate use of the relations between temperatures of the low (t2) and high (t3) ionization gas zones derived for H II regions in AGN chemical abundance studies. Using a photoionization model grid, we derived a new expression for t2 as a function of t3 valid for Seyfert 2 nuclei. The use of this new expression in the AGN estimation of the O/H abundances based on Te-method produces O/H abundances slightly lower (about 0.2 dex) than those derived from detailed photoionization models. We also find that the new formalism for the Te-method reduces by about 0.4 dex the O/H discrepancies between the abundances obtained from strong emission-line calibrations and those derived from direct estimations.

description: The primary objectives of this research are: (1) to identify the preferences of Connecticut apple consumers regarding product attributes and market characteristics; (2) to assess the impact of Connecticut promotion programs on consumer preference for Connecticut grown apples, and (3) to identify opportunities for more effective marketing of Connecticut grown apples. Information was obtained by interviewing a total of 374 persons purchasing apples at farm stores, pick-your-own orchards, supermarkets, and warehouse stores. Data collection included both direct questions and customer ranking of eight displayed apples. Each of the eight apples was either McIntosh or Red Delicious, 49 or 79 cents per pound, red or relatively green, large or small. Connecticut grown or unspecified origin, waxed or not waxed, and bruised or unbruised. The percentage of customers reporting an awareness of a general promotion program, known as Connecticut Grown, varied from a low of 8.7 percent at farm stores to a high of 32.6 percent at pick-your-own orchards. A somewhat lower percentage of customers reported that they had heard a radio advertisement specifically promoting Connecticut grown apples. Customers rated appearance, texture, sweetness and price as more important than Connecticut grown in deciding which apples to buy. A positive relation, however, was found between awareness of the promotion programs and the importance of Connecticut grown. A customer listing of three favorite apple varieties in order of preference revealed McIntosh to be the most popular first choice at farm stores, pick-your-own orchards, and warehouse stores. Red Delicious was the most popular first choice at supermarkets. Customer ranking of the eight displayed apples with seven attributes in various combinations revealed a preference for low price, a high percentage of red color, large size, waxed, and unbruised. Implied preferences regarding variety and origin were not statistically significant for the composite sample. Data from the ranking experiment were subdivided with regard to customer awareness of each of the two promotion programs. Awareness of the promotion programs was associated with a relatively strong preference for Connecticut grown and a relatively weak preference for low price, waxed, and unbruised.

description: Optical pulling forces or tractor beams can pull particles against light propagation by redirecting the incident photons forward. This is typically achieved using Bessel beams with very small half-cone angles, which considerably limits its applicability. One can circumvent such issue by using a superposition of plane waves. In order to investigate optical pulling forces exerted by a pair of non-colinear plane waves, we develop a theoretical framework based on Mie theory, Debye potentials and Wigner rotation matrices. We apply this framework to calculate the optical pulling force on metallo-dielectric composite particles, which we put forward as an alternative material platform to optimize and tailor tractor beams. Indeed we demonstrate that by adding a few plasmonic inclusions to low-refractive index dielectric particles of arbitrary sizes, we are able to produce polarization dependent optical pulling forces that cannot occur in the corresponding homogeneous particles. Altogether our findings not only provide innovative theoretical methods to compute optical pulling forces, but also provide new strategies to tailor and optimize them, paving the way to increase their applicability.

Characterisation of the collagen binding domain of gelatinase A : involvement of specific residues in the fibronectin type II modules in substrate recognition
Creators: name: Moore, Todd Robert
Publisher: name: University of British Columbia
Year: 2009

description: The matrix metalloproteinase (MMP) family of endopeptidases can collectively degrade many components of the extracellular matrix. Their proteolytic activities have been implicated in normal processes such as extracellular matrix turnover and certain pathological conditions such as periodontitis, arthritis, and tumour metastasis. Based upon domain composition gelatinase A is separated from the other MMPs by the insertion of three contiguous fibronectin type II modules into its catalytic domain. Since it was determined that a recombinant domain consisting of the three fibronectin type II modules bound to native type I collagen this domain was termed the collagen binding domain (CBD). The function of the CBD is to donate substrate binding exosites to allow for broader enzyme specificity. Considering that the CBD contains exosites for binding native/denatured collagen, this domain was subjected to site-directed mutagenic studies to elucidate essential residues involved in collagen binding. The binding properties of the collagen binding domain to denatured type I collagen (gelatin) was investigated using a recombinant protein constructed of the second and third fibronectin type II module (rCBD23). Ten mutations were performed within the rCBD23 protein. Since the binding of substrate to the CBD is via a hydrophobic pocket, the mutations F264A, F264Y, F266A, F266Y, F322A, F324A, F322Y, F324Y, F264A/F322A, and F266A/F324A were introduced into rCBD23 in order to determine the effect of removing hydrophobic character. It was found that there was a decrease in the binding of the mutant proteins that was proportional to the distance between the mutated residue side chain and a strictly conserved tryptophan at the base of the hydrophobic pocket. Complete abrogation of gelatin binding was observed in the double mutant F266A/F324A. The observed effect was proposed to be the result of destabilisation of the strictly conserved tryptophan that forms the base of the hydrophobic pocket. These studies have furthered our knowledge and understanding of the interactions of CBD with substrate. The present study, combined with results from other studies, could be used to synthesize compounds that are specific to the CBD and are able to irreversibly inhibit the binding of CBD to substrate. A drug that would preferentially block binding of the CBD to collagen is proposed to reduced the metastasis of tumour cells by abolishment of type IV collagen binding. The overall effect is decreased tumour migration from the primary site of development and therefore substantially decreasing tumour progression.

description: When common factors strongly influence two cross-correlated time series recorded in complex natural and social systems, the results will be biased if we use multifractal detrended cross-correlation analysis (MF-DXA) without considering these common factors. Based on multifractal temporally weighted detrended cross-correlation analysis (MF-TWXDFA) proposed by our group and multifractal partial cross-correlation analysis (MF-DPXA) proposed by Qian et al., we propose a new method---multifractal temporally weighted detrended partial cross-correlation analysis (MF-TWDPCCA) to quantify intrinsic power-law cross-correlation of two non-stationary time series affected by common external factors in this paper. We use MF-TWDPCCA to characterize the intrinsic cross-correlations between the two simultaneously recorded time series by removing the effects of other potential time series. To test the performance of MF-TWDPCCA, we apply it, MF-TWXDFA and MF-DPXA on simulated series. Numerical tests on artificially simulated series demonstrate that MF-TWDPCCA can accurately detect the intrinsic cross-correlations for two simultaneously recorded series. To further show the utility of MF-TWDPCCA, we apply it on time series from stock markets and find that there exists significantly multifractal power-law cross-correlation between stock returns. A new partial cross-correlation coefficient is defined to quantify the level of intrinsic cross-correlation between two time series.

Year: 2005
Subjects: subject: Astrophysics (astro-ph)

description: We use the distribution of gravitationally-lensed image separations observed in the Cosmic Lens All-Sky Survey (CLASS) and the PMN-NVSS Extragalactic Lens Survey (PANELS), which are (nearly) complete for the image separation range $0''.3 \le Δθ\le 6''$, to constrain a model velocity dispersion function (VF) of early-type galaxies. Assuming a current concordance cosmological model and adopting a singular isothermal ellipsoid (SIE) model for galactic potentials, we consider constraining both a characteristic velocity dispersion (parameter $σ_*$) and the shape of the function (parameters $α$ and $β$; Sheth et al. 2003) for $0.3 \la z \la 1 $. If all three parameters are allowed to vary, then none of the parameters can be tightly constrained by the lensing data because of the small size of the sample. If we fix the shape of the function by either the SDSS local stellar VF or an inferred local stellar VF based on the SSRS2 galaxy sample, then the constrained values of $σ_*$ are nearly equal to the corresponding stellar values; we have $f_{\rm SIE/center} (\equiv σ_{*{\rm SIE}}/σ_{*{\rm center}})= 0.90\pm 0.18 {\rm (SDSS)}$ or $1.04 \pm 0.19 {\rm (SSRS2)}$ assuming non-evolution of the function between the present epoch and $z \sim 0.6$. Finally, using only the CLASS statistical sample (Browne et al. 2003) and thus including an absolute multiple-imaging probability, we find that the SDSS stellar VF may have significantly underestimated the abundance of morphologically early-type galaxies.

description: We address the problem of calculating momentum distributions of particles emerging from the three-body decay of a many-body resonance. We show that these distributions are determined by the asymptotics of the coordinate-space complex-energy wave-function of the resonance. We use the hyperspherical adiabatic expansion method where all lengths are proportional to the hyperradius. The structures of the resonances are related to different decay mechanisms. For direct decay all inter-particle distances increase proportional to the hyperradius at intermediate and large distances. Sequential three-body decay proceeds via spatially confined quasi-stationary two-body configurations. Then two particles remain close while the third moves away. The wave function may contain mixtures which produce coherence effects at small distances, but the energy distributions can still be added incoherently. Two-neutron halos are discussed in details and illustrated by the $2^+$ resonance in $^{6}$He. The dynamic evolution of the decay process is discussed.

description: This article reviews the legal standards and the economics of indirect purchaser cases. Drawn from recent cases on behalf of consumers in the ADM price fixing case, it presents cost pass through models for high fructose corn syrup (HFCS), one of the alleged price fixes in the wet corn milling industry. If soft drink bottlers, a primary user of HFCS, have fixed proportion production, constant returns to scale, and if other bottlers input prices are unaffected by variations in soft drink output due to the price fix, then the impact of the price fix on bottlers' cost is equal to the increase in the price of HFCS. The extent of pass through of the increase by bottlers is shown to depend critically upon the market structure of the bottling industry and the shape of the retail demand curve. Flexible demand functional forms are needed to avoid constraining estimated pass through rates to levels above or below full, 100 percent, pass through.

description: Large-scale exoplanet search surveys have shown evidence that atmospheric escape is a ubiquitous process that shapes the evolution and demographics of planets. However, we lack a detailed understanding of this process because very few exoplanets discovered to date could be probed for signatures of atmospheric escape. Recently, the metastable helium triplet at 1.083 $μ$m has been shown to be a viable window for the presence of He-rich escaping envelopes around short-period exoplanets. Our objective is to use, for the first time, the Phoenix spectrograph to search for helium in the upper atmosphere of the inflated hot Jupiter WASP-127 b. We observed one transit and reduced the data manually since there is no pipeline available. We did not find a significant in-transit absorption signal indicative of the presence of helium around WASP-127 b, and set a 90% confidence upper limit for excess absorption at 0.87% in a 0.075 nm passband covering the He triplet. Given the large scale height of this planet, the lack of a detectable feature is likely due to unfavorable photoionization conditions to populate the metastable He triplet. This conclusion is supported by the inferred low coronal and chromospheric activity of the host star and the old age of the system, which result in a relatively mild high-energy environment around the planet.

description: This paper is an essay in political economy. It defines globalization and discusses its key role in economic development over the past two centuries as well as today. Globalization may have broadened markets, thereby affecting the nature of competition within those larger markets, or it may have simply introduced more trade or foreign direct investment to existing markets. One conclusion is that there is no global market for high value food, or for any particular high value food. To date the impacts of multinational firms in political forums at the state, regional or national as well as the global level have been in many instances as important as their impacts on economic markets. Issues and concerns discussed range from general observations on governance of the global economy to the impact of global concentration on specific problems in the agricultural and food markets of the United States. We conclude that the scope and extent of public policy is a direct function of the degree of development and globalization in an economy.

description: This paper examines friction as a function of the sliding velocity and applied normal load from air to UHV in a scanning force microscope (SFM) experiment in which a sharp silicon tip slides against a flat Si(100) sample. Under ambient conditions, both surfaces are covered by a native oxide, which is hydrophilic. During pump-down in the vacuum chamber housing the SFM, the behavior of friction as a function of the applied normal load and the sliding velocity undergoes a change. By analyzing these changes it is possible to identify three distinct friction regimes with corresponding contact properties: (a) friction dominated by the additional normal forces induced by capillarity due to the presence of thick water films, (b) higher drag force from ordering effects present in thin water layers and (c) low friction due to direct solid-solid contact for the sample with the counterbody. Depending on environmental conditions and the applied normal load, all three mechanisms may be present at one time. Their individual contributions can be identified by investigating the dependence of friction on the applied normal load as well as on the sliding velocity in different pressure regimes, thus providing information about nanoscale friction mechanisms.

description: Causal inference methods based on conditional independence construct Markov equivalent graphs, and cannot be applied to bivariate cases. The approaches based on independence of cause and mechanism state, on the contrary, that causal discovery can be inferred for two observations. In our contribution, we challenge to reconcile these two research directions. We study the role of latent variables such as latent instrumental variables and hidden common causes in the causal graphical structures. We show that the methods based on the independence of cause and mechanism, indirectly contain traces of the existence of the hidden instrumental variables. We derive a novel algorithm to infer causal relationships between two variables, and we validate the proposed method on simulated data and on a benchmark of cause-effect pairs. We illustrate by our experiments that the proposed approach is simple and extremely competitive in terms of empirical accuracy compared to the state-of-the-art methods.

description: This paper presents the results of a case study, which aims to reflect on the relationship of the violence and social cohesion in a specific territory. This is a phenomenological research and its methodological approach a combination between quantitative and qualitative methods. This study found that there is statistical significance between the variables addressed, to the conclusion that there is a relationship between violence and the level of social cohesion. To test this relationship is also built an indicator of social cohesion from a survey and the adaptation of several surveys of social cohesion.

description: This paper discussed food quality issues associated with both food safety and food nutritional content. Policy approaches to satisfying consumer demands for safe, nutritious food are described from administrative as well as economic perspectives. Current priority issues include instituting better ways of reducing risks from microbial pathogens, from agricultural chemical residues, and - on the nutritional front - enhancing the nutritional profile of consumers' diets. Nutrition labeling changes have been achieved. Thus, dietary change must be attained primarily through effective means of enhancing nutritional knowledge, changing attitudes and, ultimately, behavior. The paper concludes by considering the development of the next agricultural/food legislation and the chances of integrating food quality issues in the general legislation.

description: We present results of our analysis of NuSTAR data of the luminous infrared galaxy Mrk 266, which contains two nuclei, SW and NE, resolved in previous Chandra imaging. Combining with the Chandra data, we intepret the hard X-ray spectrum obtained from a NuSTAR observation as resulting from steeply rising flux from a Compton-thick AGN in the SW nucleus which is very faint in the Chandra band, confirming the previous claim of Mazzarella et al. (2012). This hard X-ray component is dominated by reflection, and its intrinsic 2-10 keV luminosity is likely to be ~1e43 erg/s. Although it is bright in soft X-ray, only moderately absorbed NE nucleus has a 2-10 keV luminosity of 4e41 erg/s, placing it in the low-luminosity AGN class. These results have implications for understanding the detectability and duty cycles of emission from dual AGN in heavily obscured mergers.

description: This paper examines structural and strategic factors affecting price determination in the branded cottage cheese industry. Special emphasis is placed on the presence and conduct of cottage cheese brands marketed by dairy cooperatives. The data examined in this study cover cottage cheese sales in 47 markets for the fourth quarter of 1988. We find evidence supporting the premise that market power is being exercise in the cottage cheese market. One of the strongest influences of the price of cottage cheese is the extent of market penetration of the brand. Brands' prices rise with an increase in the price of private label cottage cheese. We also find strong evidence that cooperatives are not exercising market power. Cooperatives charge a lower price than their IOF competition under the same conditions and, unlike their IOF competition, co-ops do not capitalize on higher share to raise price. Moreover, the presence of cooperatives in a market brings the price of competing brands down. Cooperatives do not differ greatly from IOFs in the use of merchandising tools, using them as much or slightly more in most cases.

description: The efforts to generate clear and precise concepts about vulnerability and habitat have resulted in the simplification and loss of clarity of these concepts. Despite their importance to human life, they have lost support and have been reduced to “assumptions” that are used in common parlance and sometimes inappropriately. The main objective of this article is to reflect on vulnerability and habitat as holistic and integrated concepts. For this purpose a literature review of various scientific texts was carried out and some explanatory models to interpret it were proposed, concluding that these concepts must be understood through their interrelation in the social construction of territory.

description: The accurate determination of atomic masses and the high-precision measurement of the bound-electron g factor are prerequisites for the determination of the electron mass, which is one of the fundamental constants of nature. In the 2002 CODATA adjustment [P. J. Mohr and B. N. Taylor, Rev. Mod. Phys. 77, 1 (2005)], the values of the electron mass and the electron-proton mass ratio are mainly based on g factor measurements in combination with atomic mass measurements. In this paper, we briefly discuss the prospects for obtaining other fundamental information from bound-electron g factor measurements, we present some details of a recent investigation of two-loop binding corrections to the g factor, and we also investigate the radiative corrections in the limit of highly excited Rydberg S states with a long lifetime, where the g factor might be explored using a double resonance experiment.

Alternative visions of "Harmony" : exploring gender and participation in the Malcolm Island Community Resource Cooperative
Creators: name: Pullen, Mary MacLaren
Publisher: name: University of British Columbia
Year: 2009

description: The cooperative enterprise has seemed, to many contemporary 'green' theorists, to be a socially sustainable economic alternative to conventional corporate capitalism, based on the ideas of grassroots participation, democracy, egalitarianism, community, social equity and empowerment. I argue, however, that there has been no attempt in 'green' thought to analyze gender relations within the cooperative enterprise. Instead, 'green' theorists view the cooperative as a homogeneous social entity with a shared subjectivity; and assume that the cooperative's 'sustainable' attributes - decentralized, democratic, and equitable principles - will ensure gender equity and empowerment through social sustainability. Reviewing 'green' theories of cooperatives and social sustainability, this thesis challenges 'green' interpretations of participation and social sustainability that ignore members' gendered identities, relations, and interests, particularly in resource-dependent communities. 'Green' definitions of participation have tended to narrowly focus on access to the cooperative without paying attention to cooperative member dynamics. By focusing attention on the nuances of participation and the implications for equity and empowerment, this thesis explores the complexities and contradictions of gender and participation as they apply to a mixed-gender community resource cooperative on Malcolm Island, British Columbia. Using a labour-knowledge-authority framework, the case study of the Malcolm Island Community Resource Cooperative (MICRC) illustrates that while the cooperative may be socially sustainable according to 'green' community and social economic ideals, actual participation in the cooperative enterprise is more complex, contradictory, and gendered than 'green' thought has typically assumed.
