description: Linear transformation techniques such as singular value decomposition (SVD) have been used widely to gain insight into the qualitative dynamics of data generated by dynamical systems. There have been several reports in the past that had pointed out the susceptibility of linear transformation approaches in the presence of nonlinear correlations. In this tutorial review, local dispersion along with the surrogate testing is proposed to discriminate nonlinear correlations arising in deterministic and non-deterministic settings.

description: The economic effects of the mountain pine beetle outbreak in British Columbia are simulated using a multi-region spatial price equilibrium model coupled with a stochastic dynamic updating procedure. The simulation captures expected changes in the B.C. timber supply, growth of plantation forests in the southern hemisphere and an escalating Russian log export tax. The results indicate lumber and log prices will rise in B.C., offsetting some of the economic loss to timber producers. However, on net producers in the B.C. forest industry will experience a decrease in economic surplus.

description: After controlling a variety of feeder cattle characteristics and market and sale conditions in Iowa feeder auctions, the price premiums for preconditioning claims (vaccinations and minimum 30 days of weaning) with and without third-party certification (TPC) are estimated as $6.12/cwt and $3.35/cwt, respectively. These premiums differ statistically (p<0.0001), and their difference exceeds the average participation cost of TPC ($1/cwt). This indicates that TPC is valued in the market to credibly signal preconditioning investment under asymmetric information.

description: Southeast drought conditions have accentuated the demand for irrigation in the face of restricted water supply. For allocating this supply, Georgia held an auction for withdrawing irrigated acreage. This auction withdrew 33,000 acres from irrigation, resulting in a physical estimate of a 399 acre-feet daily increase in water flow. The actual reduction is driven by crop distributional changes on the basis of economic substitution and expansion effects. In contrast to the physical estimates, an econometric model that considers these effects is developed. The differences between the physical and econometric models result in an increase in the estimate of water savings of around 19% to 24%.

description: Sex ratio theory predicts both mean sex ratio and variance under a range of population structures. Here, we compare two genera of phoretic nematodes (Parasitodiplogaster and Ficophagus spp.) associated with 12 fig pollinating wasp species in Panama. The host wasps exhibit classic local mate competition: only inseminated females disperse from natal figs, and their offspring form mating pools that consist of scores of the adult offspring contributed by one or a few foundress mothers. By contrast, in both nematode genera, only sexually undifferentiated juveniles disperse and their mating pools routinely consist of 10 or fewer adults. Across all mating pool sizes, the sex ratios observed in both nematode genera are consistently female-biased (approx. 0.34 males), which is markedly less female-biased than is often observed in the host wasps (approx. 0.10 males). In further contrast with their hosts, variances in nematode sex ratios are also consistently precise (significantly less than binomial). The constraints associated with predictably small mating pools within highly subdivided populations appear to select for precise sex ratios that contribute both to the reproductive success of individual nematodes, and to the evolutionary persistence of nematode species. We suggest that some form of environmental sex determination underlies these precise sex ratios.
Sand and sawdust bedding affect populations of coliforms, Klebsiella spp. and Streptococcus spp. on teat ends of dairy cows housed in freestalls

Year: 2009

description: The main objectives of the study were: 1) to compare bacterial populations of mastitis causing organisms on the outside of teats of lactating cows housed on sand and on sawdust bedding and, 2) to examine the relationship between bacterial counts in the two bedding types with those on teat ends. Sixteen cows were housed on either sand or sawdust-bedded freestalls using a crossover design with 3 week per bedding type. Bedding samples were collected on d 0 (prior to cows lying on the bedding), 1, 2 and 6. Teat ends were sampled prior to the morning milking on d 1, 2 and 6. All samples were analyzed to determine coliform, Klebsiella spp., and Streptococcus spp. populations. For teat end samples, there was two times more coliform and six times more Klebsiella spp. on teat ends of cows housed on sawdust compared to those housed on sand. In contrast, there was a 10-fold increase in the number of Streptococcus spp. associated with sand than with sawdust. In both sawdust and sand bedding, coliform, Klebsiella and Streptococcus counts increased over each experimental week, although patterns varied with bedding and bacteria type. Bacterial counts on teat ends were correlated to bacterial counts in sawdust: r = 0.47, r = 0.69 and r = 0.60 for coliforms, Klebsiella spp. and streptococci, respectively. Bacterial counts on teat ends were correlated to bacterial counts in sand: r = 0.35 for coliforms and r = 0.40 for Klebsiella spp. Streptococcal counts on teat ends were not correlated to bacterial counts in sand. In conclusion, coliform and Klebsiella spp. on teat ends were more numerous when using sawdust bedding, but Streptococcus spp. were more numerous on teat ends of cows housed on sand.

description: ABSTRACT The UK retail banking sector in the recent years has witnessed a significant transformation in service delivery due, in large part, to the advancement in technology and innovations. Many on-site banking services are now delivered through technology-based service delivery channels such as Self-Service Kiosks and Automat- ed Teller Machines. The quality of services offered by retail banks plays a key role in enhancing their market competitive positions. This paper proposes a hybrid approach for measuring qualities of traditional and automated on-site retail banking services. The authors carried out a comprehensive chronological review of literature, 36 papers, in service quality and service excellence, marketing and related topics. The review found a lack of distinctive frameworks for measuring on-site banking services delivered through traditional and automated channels. The authors evaluated—and diligently revised—the existing main models for measuring the quality of services in the retail banking sector. The authors proposed two hybrid frameworks, traditional and automat- ed service quality measurements, by rationally combining and aggregating the dimensions SERVQUAL and Service Excellence Model. The proposed frameworks consist of wider dimensions than, arguably, well-known existing models of service quality measurements. Keywords: Service Quality, Service Excellence, Aggregated Service Excellence, Aggregated Automated Service Excellence, Aggregated Traditional Service Excellence, Customer Satisfaction

description: This is an analytical study of pinning and spontaneous vortex phase is a system consisting of a superconducting thin film pierced by a long ferromagnetic columnar defect of finite radius $R$. The magnetic fields, screening currents, energy and pinning forces for this system are calculated. The interaction between the magnetic field of vortices and the magnetization outside the plane of the film and its close proximity enhances vortex pinning significantly. Spontaneous vortex phase appears when the magnetization of the columnar defect is increased above a critical value. Transitions between phases characterized by different number of flux quanta are also studied. These results are generalized to the case when the superconductor is pierced by an array of columnar defects.

description: In customary international and public law, “takings” resulting from regulations designed to protect the public good are generally excluded from compensation rules; this exclusion is known as a police powers carve-out (PPCO). Increasingly, this PPCO is being challenged, particularly in international investment law. This paper analyzes the efficiency properties of a PPCO in a model with endogenous regulation, investment and entry. We design a one-parameter family of carve-out/compensation schemes that induce efficient regulation and firm level investment even when the regulator suffers fiscal illusion and the social benefit from regulation is private information to the regulator. We show that offering a carve-out reduces the subsidy to risky industry implicit in compensation rules; thus, a carve-out can mitigate the entry problem.
Covariance of the redshift-space matter power spectrum after reconstruction

description: We explore the covariance of redshift-space matter power spectra after a standard density-field reconstruction. We derive perturbative formula of the covariance at the tree-level order and find that the amplitude of the off-diagonal components from the trispectrum decreases by reconstruction. Using a large set of N-body simulations, we also find the similar reduction of the off-diagonal components of the covariance and thereby the signal-to-noise ratio (S/N) of the post-reconstructed (post-rec) power spectra significantly increases compared to the pre-reconstructed spectra. This indicates that the information leaking to higher-order statistics come back to the two-point statistics by reconstruction. Interestingly, the post-rec spectra have higher S/N than the linear spectrum with Gaussian covariance when the scale of reconstruction characterized with the smoothing scale of the shift field is below ~10Mpc/h where the trispectrum becomes negative. We demonstrate that the error of the growth rate estimated from the monopole and quadrupole components of the redshift-space matter power spectra significantly improves by reconstruction. We also find a similar improvement of the growth rate even when taking into account the super-sample covariance, while the reconstruction cannot correct for the field variation of the super-sample modes.

description: The tendency to foreshorten time units as we peer further into the future provides an explanation for hyperbolic discounting at an intergenerational time scale. We study implications of hyperbolic discounting for climate change policy, when the probability of a climate-induced catastrophe depends on the stock of greenhouse gasses. We provide a positive analysis by characterizing the set of Markov perfect equilibria (MPE) of the intergenerational game amongst a succession of policymakers. Each policymaker reflects her generation’s preferences, including its hyperbolic discounting. For a binary action game, we compare the MPE set to a “restricted commitment” benchmark. We compare the associated “constant equivalent discount rates” and the willingness to pay to control climate change with assumptions and recommendations in the Stern Review on Climate Change.
Entanglement of Assistance is not a bipartite measure nor a tripartite monotone

description: The entanglement of assistance quantifies the entanglement that can be generated between two parties, Alice and Bob, given assistance from a third party, Charlie, when the three share a tripartite state and where the assistance consists of Charlie initially performing a measurement on his share and communicating the result to Alice and Bob through a one-way classical channel. We argue that if this quantity is to be considered an operational measure of entanglement, then it must be understood to be a tripartite rather than a bipartite measure. We compare it with a distinct tripartite measure that quantifies the entanglement that can be generated between Alice and Bob when they are allowed to make use of a two-way classical channel with Charlie. We show that the latter quantity, which we call the entanglement of collaboration, can be greater than the entanglement of assistance. This demonstrates that the entanglement of assistance (considered as a tripartite measure of entanglement), and its multipartite generalizations such as the localizable entanglement, are not entanglement monotones, thereby undermining their operational significance.

description: How potential entrants to an open-access fishery form their expectations determines the fishery’s adjustment path to a steady state but not the steady state values themselves. It is well known that, in the standard model with myopic expectations (those based on current values), boats enter the fishery only when the fish stock is greater than its steady state stock. We show that, with rational expectations (perfect foresight), however, boats may enter when the fish stock is much lower than its steady state value if the boat fleet is sufficiently small. This paper contrasts myopic and rational expectations within a general dynamic model of an open-access fishery.

description: The evolution of primordial black holes in a flat Friedmann universe with a massless scalar field is investigated in fully general relativistic numerical relativity. A primordial black hole is expected to form with a scale comparable to the cosmological apparent horizon, in which case it may go through an initial phase with significant accretion. However, if it is very close to the cosmological apparent horizon size, the accretion is suppressed due to general relativistic effects. In any case, it soon gets smaller than the cosmological horizon and thereafter it can be approximated as an isolated vacuum solution with decaying mass accretion. In this situation the dynamical and inhomogeneous scalar field is typically equivalent to a perfect fluid with a stiff equation of state $p=ρ$. The black hole mass never increases by more than a factor of two, despite recent claims that primordial black holes might grow substantially through accreting quintessence. It is found that the gravitational memory scenario, proposed for primordial black holes in Brans-Dicke and scalar-tensor theories of gravity, is highly unphysical.

description: Disagreement over the form of regulation of greenhouse gasses motivates a comparison of market based and command and control policies. More efficient policies can increase aggregate marginal abatement cost, resulting in higher emissions. Multiple investment equilibria and “regulatory uncertainty” arise when firms anticipate command and control policies. Market based policies eliminate this uncertainty. Command and control policies cause firms to imitate other firms’ investment decisions, leading to similar costs and small potential efficiency gains from trade. Market based policies induce firms to make different investment decisions, leading to different costs and large gains from trade. We imbed the regulatory problem in a “global game” and show that the unique equilibrium to that game is constrained socially optimal.

description: Obesity and overweight are rapidly escalating in developing countries, contributing to non-communicable diseases among young people across all socioeconomic classes and regions. Globalization has led to a nutrition transition, where home-cooked meals have been replaced by ultra-processed foods, causing a shift from predominately underweight societies to obese ones. As a result, alarming childhood obesity is emerging in many developing countries where being underweight remains persistent, leading to a complex coexisting issue called the double burden of malnutrition. Malnutrition in all forms is a concerning public health issue, and efforts to reduce malnutrition, until now, have emphasized the importance of reducing undernutrition. This scoping review examined how school-based nutrition programs could impact the double burden of malnutrition and found three themes of influence: state of school feeding, policies, and sustainability. The future planning of school meals must consider these themes when choosing, planning, and implementing healthy school meals.

description: A first-order relativistic wave equation is constructed in five dimensions. Its solutions are eight-component spinors, which are interpreted as single-particle fermion wave functions in four-dimensional spacetime. Use of a ``cylinder condition'' (the removal of explicit dependence on the fifth coordinate) reduces each eight-component solution to a pair of degenerate four-component spinors obeying the Dirac equation. This five-dimensional method is used to obtain solutions for a free particle and for a particle moving in the Coulomb potential. It is shown that, under the cylinder condition, the results are the same as those from the Dirac equation. Without the cylinder condition, on the other hand, the equation predicts some interesting new phenomena. It implies the existence of a scalar potential, and for zero-mass particles it leads to a four-dimensional fermionic equation analogous to Maxwell's equation with sources.

Open 24 hours : a case study of Vancouver and the twenty-four hour city concept
Creators: name: Johnston, Jennifer Lee
Publisher: name: University of British Columbia
Year: 2009

description: Vancouver has been experiencing a new phase of change that is associated with globalization, the convergence of technology, culture and urban development and demographic factors. In recent years Vancouver's economic base has undergone transformation with a shift in capital and labour from mass production and manufacturing ("Fordist" production), to high-technology productions and producer services. More recently, Vancouver's 'new economy' has become increasingly focussed on the tourist, film and television industry. Market forces and social processes have transformed Vancouver's urban core while planning and local policy initiatives have also been influential agents of change. The City of Vancouver's Central Area Plan (1991) successfully placed emphasis on the importance of downtown residential living. Consequently, Vancouver's downtown has evolved into a place to work, live and socialize creating new social conflicts and tensions. The time has arrived for a new plan to guide the future of Vancouver's Central Area that shifts the focus of policy from 'hard' physical spatial planning to encompass and address 'softer' social and behavioural issues that are increasingly important for future planning endeavours. Vancouver is a dynamic and diverse transnational city with a growing urban population and vibrant central area. As a result, planners are faced with the ongoing challenge of providing livable urban communities while still responding to how people both live and socialize through new and innovative planning schemes. The Twenty-Four Hour City concept offers an opportunity to inform new policy and planning strategy through experimentation and innovation.

description: We propose a method to suppress the chemical reactions between ultracold bosonic ground-state $^{23}$Na$^{87}$Rb molecules based on optical shielding. By applying a laser with a frequency blue-detuned from the transition between the lowest rovibrational level of the electronic ground state $X^1Σ^+ (v_X=0, j_X=0)$, and the long-lived excited level $b^3Π_0 (v_b=0, j_b=1)$, the long-range dipole-dipole interaction between the colliding molecules can be engineered, leading to a dramatic suppression of reactive and photoinduced inelastic collisions, for both linear and circular laser polarizations. We demonstrate that the spontaneous emission from $b^3Π_0 (v_b=0, j_b=1)$ does not deteriorate the shielding process. This opens the possibility for a strong increase of the lifetime of cold molecule traps, and for an efficient evaporative cooling. We also anticipate that the proposed mechanism is valid for alkali-metal diatomics with sufficiently large dipole-dipole interactions.

description: The paper analyzes competition among supermarkets in Brazil. In contrast to part of the economic literature which suggests that the fast growth of big supermarket chains would destroy independent, medium and small supermarkets, the paper argues that big supermarket chains can coexist with different formats of independent food retailing. As a result, competition in food retail is complex and cannot be described as a simple Darwinian process of market concentration. The analysis is divided in two parts. In the first part, the competition between hypermarkets and supermarkets is examined. Evidences for the district of Sao Paulo, Brazil, suggest that these retailers form separate markets. The second part is focused on neighborhood supermarkets. The results differ from the general belief that independent supermarkets establish higher prices in comparison to big chain supermarkets. The analysis brings to light the heterogeneity of the competitive fringe in the oligopoly model of Brazilian retailing.

description: The new EU Animal Health Strategy suggests a shift in emphasis away from control towards prevention and surveillance activities for the management of threats to animal health. The optimal combination of these actions will differ among diseases and depend on largely unknown and uncertain costs and benefits. This paper reports an empirical investigation of this issue for the case of Avian Influenza. The results suggest that the optimal combination of actions will be dependent on the objective of the decision maker and that conflict exists between an optimal strategy which minimises costs to the government and one which maximises producer profits or minimises negative effects on human health. From the perspective of minimising the effects on human health, prevention appears preferable to cure but the case is less clear for other objectives.

description: A density functional theory is used to investigate the instability arising in superfluid $^4$He as it flows at velocity u just above the Landau critical velocity of rotons v_c. Confirming an early theoretical prediction by one of us [JETP Lett. 39, 511 (1984)], we find that a stationary periodic modulation of the density occurs, with amplitude proportional to (u-v_c)^{1/2} and wave vector equal to the roton wave vector. This density pattern is studied for supercritical flow both in bulk helium and in a channel of nanometer cross-section.

description: We describe a time evolution algorithm for quantum spin chains whose Hamiltonians are composed of an infinite uniform left and right bulk part, and an arbitrary finite region in between. The left and right bulk parts are allowed to be different from each other. The algorithm is based on the time-dependent variational principle (TDVP) of matrix product states. It is inversion-free and very simple to adapt from an existing TDVP code for finite systems. The importance of working in the projective Hilbert space is highlighted. We study the quantum Ising model as a benchmark and an illustrative example. The spread of information after a local quench is studied in both the ballistic and the diffusive case. We also offer a derivation of TDVP directly from symplectic geometry.

description: We present an analysis of the rotation measures (RMs) of polarized extragalactic point sources in the Southern Galactic Plane Survey. This work demonstrates that the statistics of fluctuations in RM differ for the spiral arms and the interarm regions. Structure functions of RM are flat in the spiral arms, while they increase in the interarms. This indicates that there are no correlated RM fluctuations in the magneto-ionized interstellar medium in the spiral arms on scales larger than ~ 0.5 deg, corresponding to ~ 17 pc in the nearest spiral arm probed. The non-zero slopes in interarm regions imply a much larger scale of RM fluctuations. We conclude that fluctuations in the magneto-ionic medium in the Milky Way spiral arms are not dominated by the mainly supernova-driven turbulent cascade in the global ISM but are probably due to a different source, most likely H II regions.

Soft X-ray and Ultraviolet Emission Relations in Optically Selected AGN Samples

description: Using a sample of 228 optically selected Active Galactic Nuclei (AGNs) in the 0.01-6.3 redshift range with a high fraction of X-ray detections (81-86%), we study the relation between rest-frame UV and soft X-ray emission and its evolution with cosmic time. The majority of the AGNs in our sample (155 objects) have been selected from the Sloan Digital Sky Survey (SDSS) in an unbiased way, rendering the sample results representative of all SDSS AGNs. The addition of two heterogeneous samples of 36 high-redshift and 37 low-redshift AGNs further supports and extends our conclusions. We confirm that the X-ray emission from AGNs is correlated with their UV emission, and that the ratio of the monochromatic luminosity emitted at 2keV compared to 2500A decreases with increasing luminosity (a_ox=-0.136 l_uv+2.616, where l_uv is in log units), but does not change with cosmic time. These results apply to intrinsic AGN emission, as we correct or control for the effects of the host galaxy, UV/X-ray absorption, and any X-ray emission associated with radio emission in AGNs. We investigate a variety of systematic errors and can thereby state with confidence that (1) the a_ox-l_uv anti-correlation is real and not a result of accumulated systematic errors and (2) any a_ox dependence on redshift is negligible in comparison. We provide the best quantification of the a_ox-l_uv relation to date for normal radio-quiet AGNs; this should be of utility for researchers pursuing a variety of studies.

Joint-liability borrowing decisions under risk: Empirical evidence from rural microfinance in Ethiopia

description: This paper investigates borrowing decisions of rural households from a microfinance in Tigray, Ethiopia using household panel data on 5 years and a dynamic panel probit model. The theoretical model takes two types of risk involved in joint-liability lending explicitly into account: risk of partner failure and the risk of losing future access to credit. Empirical results show that these risks are important in explaining borrowing decisions. Another finding is that the probability of repeat-borrowing is higher than the probability of new participation, with possible implications that perceived joint-liability threats deter participation and easing stringent punishments might help poor households’ access to credit.
La representación discursiva del desarrollo en el discurso del gremio empresarial peruano: un estudio desde el análisis crítico del discurso (ACD) de los pronunciamientos institucionales de la Confederación Nacional de Instituciones Empresariales Privadas (CONFIEP) entre los años 2011-2018

description: La Confederación Nacional de Instituciones Empresariales Privadas (Confiep) emite entre el 2011 y el 2018 una serie de pronunciamientos respecto a la coyuntura nacional para explicitar su postura al respecto. Este rango de tiempo abarca el fin del periodo de bonanza económica producto del alza de los precios de materias primas, tres gobiernos distintos, y una gran cantidad de conflictos sociales. Esta tesis analiza el concepto de desarrollo que presenta la Confiep a través de sus pronunciamientos institucionales y las formas en las que asigna roles la empresa, al Estado y la sociedad civil. Para ello, revisa los conceptos de desarrollo y progreso y su relación con la desigualdad; y recorre la historia del gremio empresarial desde sus orígenes en 1984 hasta la actualidad. El trabajo se adscribe a la propuesta de análisis crítico del discurso de Fairclough (1992) empleando el sistema de representación de actores sociales de Van Leeuwen (1997) y el sistema de transitividad de Eggins (2004) para analizar cómo el gremio empresarial caracteriza a los actores sociales y, sobre esta base, proponer dos repertorios interpretativos acerca del desarrollo. El primero de ellos lo asume como una promesa bajo amenaza y el otro como un hecho inexorable, y juntos contribuyen con estrategias distintas a la defensa del modelo económico vigente.
