description: This paper presents a ridge-to-reef case study on Philippine biodiversity conservation that focused on reducing agricultural chemicals as a contribution to development goals of optimized food security, improving water quality, and mitigating maternal malnutrition. Building upon an earlier study that engaged participants and jurisdictions, farmers were oriented on biodiversity considerations and engaged in ecologically-based rodent management that was extended across the province of Aurora through the Office of the Provincial Agriculturist. Subsequently, a Participatory Action Research and Learning (PARL) cycle was conducted among 14 farmer participants to support biodiversity friendly agriculture. Developed with local farmers, a biodiversity assessment demonstrated that organic approaches in rice farms increased arthropod biodiversity and reduced the number of key insect pests. The organizational results from this biodiversity study further indicated that local government participation can promote positive change by helping overcome the disconnect between communities and sustainability research. The approach to biodiversityfriendly agriculture reached a milestone through the collaborative development of an agricultural protected area supported by drafting a municipal ordinance to encourage the continued expansion of biodiversity-friendly agriculture and reductions in the chemical load of a key Aurora watershed. This paper discusses the biodiversity analysis and organizational results within the context of transecosystem knowledge management and the goal of improving chronic maternal malnutrition that has been identified in coastal settlements of Aurora.

description: In Part I of this series, we presented the microscopic approach to Souslin-tree constructions, and argued that all known $\diamondsuit$-based constructions of Souslin trees with various additional properties may be rendered as applications of our approach. In this paper, we show that constructions following the same approach may be carried out even in the absence of $\diamondsuit$. In particular, we obtain a new weak sufficient condition for the existence of Souslin trees at the level of a strongly inaccessible cardinal. We also present a new construction of a Souslin tree with an ascent path, thereby increasing the consistency strength of such a tree's nonexistence from a Mahlo cardinal to a weakly compact cardinal. Section 2 of this paper is targeted at newcomers with minimal background. It offers a comprehensive exposition of the subject of constructing Souslin trees and the challenges involved.

description: Abstract: Control is typically seen as a dyadic relationship, meaning that there is a controller who exercises control over another person, the controllee. Until now, research in the field of IS project control mainly focused on the controller perspective, covering aspects like control choices and its effects on project performance. This unilateral research focus has led to gaps regarding the controllee’s perspective on control mechanisms - neglecting influence of the controllee’s resulting behavior on control efficiency and effectiveness. The ongoing research presented in this paper therefore aims at investigating the factors that determine congruence between controller and controllee in an IS project setting. For this purpose, a quantitative vignette study will be conducted as an approach that is able to combine the advantages of both qualitative and quantitative research methods. Potential findings include a considerable impact of a controllee’s congruence on compliance with IS project control mechanisms. Maximizing the level of congruence could improve IS project control efficiency and effectiveness and thus help increasing IS project success.

description: Noroviruses are non-enveloped viruses with a positive-sense single-stranded RNA (ssRNA) genome belonging to the genus Norovirus, from the family Caliciviridae, which are accountable for acute gastroenteritis in humans. The Norovirus genus is subdivided into seven genogroups, i.e., (GI-GVII); among these, the genogroup II and genotype 4 (GII.4) strains caused global outbreaks of human norovirus (HuNov) disease. The viral genome comprises three open reading frames (ORFs). ORF1 encodes the nonstructural polyprotein that is cleaved into six nonstructural proteins, which include 3C-like cysteine protease (3CLpro) and a viral RNA-dependent RNA polymerase. ORF2 and ORF3 encode the proteins VP1 and VP2. The RNA-dependent RNA polymerase (RdRp) from noroviruses is one of the multipurpose enzymes of RNA viruses vital for replicating and transcribing the viral genome, making the virally encoded enzyme one of the critical targets for the development of novel anti-norovirus agents. In the quest for a new antiviral agent that could combat HuNov, high throughput virtual screening (HTVS), combined with e-pharmacophore screening, was applied to screen compounds from the PubChem database. CMX521 molecule was selected as a prototype for a similarity search in the PubChem online database. Molecular dynamics simulations were employed to identify different compounds that may inhibit HuNov. The results predicted that compound CID-57930781 and CID-44396095 formed stable complexes with MNV-RdRp within 50 ns; hence, they may signify as promising human norovirus inhibitors.

description: Lipid vesicles composed of a mixture of two types of lipids are studied by intensive Monte-Carlo numerical simulations. The coupling between the local composition and the membrane shape is induced by two different spontaneous curvatures of the components. We explore the various morphologies of these biphasic vesicles coupled to the observed patterns such as nano-domains or labyrinthine mesophases. The effect of the difference in curvatures, the surface tension and the interaction parameter between components are thoroughly explored. Our numerical results quantitatively agree with previous analytical results obtained by [Gueguen et al., Eur. Phys. J. E, 2014, vol. 37, p. 76] in the disordered (high temperature) phase. Numerical simulations allow us to explore the full parameter space, especially close to and below the critical temperature, where analytical results are not accessible. Phase diagrams are constructed and domain morphologies are quantitatively studied by computing the structure factor and the domain size distribution. This mechanism likely explains the existence of nano-domains in cell membranes as observed by super-resolution fluorescence microscopy.

description: Citizen science can be a viable mechanism to foster productive linkages between community and government for sustainable water resource management. In Australia, this potential has longstanding policy support but research into program extent, characteristics or impact on decision-making processes has been lacking. This article draws on a temporal analysis of data records from two citizen science programs and a nationwide survey of 47 program coordinators representing 43 freshwater and estuarine citizen science programs to examine these knowledge shortfalls. Results indicate that program activity has contracted in Victoria but increased in the ACT, with additional evidence indicating a nationwide contraction. Survey results revealed programs operating nationwide and largely implemented as a community-government partnership, combining data and educative priorities. Despite 70 per cent of programs having goals to inform catchment decision-making, data use was verified for less than half of programs. Program coordinators reported several social, organisational and technical barriers that limit this uptake. In highlighting these issues, we make three recommendations for enhancing linkages between citizen science and catchment decision-making: (1) increasing institutional support; (2) improving coordination and embracing new possibilities for collaboration; and (3) demonstrating and communicating program achievements.

description: Abstract: Control is often implemented in IS projects to increase project success. A typical control relationship involves two parties: A controller, who is executing control and a controllee, who is being controlled. While there is no doubt that effective and efficient control can positively influence project success, previous research has mainly focused on the controller perspective. This primarily includes the managerial aspect of control choice, i.e. creating a set of control mechanisms for a project. However, it is arguable that also the controllees’ perception of control has a considerable impact on their behavior and the resulting control effectiveness and efficiency. To close the current gap in research and get a better understanding of the controllee perspective on IS project control, explorative interviews with experienced IS project team members in Austria were held. Our summarizing content analysis yields three main findings. First, the familiarity of the project team members with each other is a crucial factor determining the perceived appropriate amount of control. Second, controllees prefer control that focuses more on the outcome rather than on their way of working. Finally, control might have a better connotation than expected and could be even seen as an opportunity to make achievements visible to supervisors.

description: The U.S. Department of Agriculture (USDA) has a long-established system for fruit and vegetable grades (USDA, Agriculture Marketing Service (AMS) 1990). A primary purpose of federal commodity grades is to facilitate the wholesale exchange by allowing sale by description rather than by inspection (Office of Technology Assessment 1977). Consequently, buyers and sellers can consummate transactions without the time and expense necessary to physically congregate in one location to inspect the commodity being sold. The result is lower transaction costs, which in turn can mean lower prices for consumers and/or higher prices for producers. Current grade standards for fruits and vegetables use attributes based on sensory characteristics,2 shelf-life considerations, palatability, or a combination of these factors. During recent years "health consciousness" has increased among consumers. Furthermore, a growing number of studies has demonstrated health benefits from various nutrients contained in relatively large amounts in fruits and vegetables (e.g., Consumer Reports 1992, p. 648). Consequently, questions arise about the feasibility and desirability of incorporating nutrient attributes into current standards or replacing the current sensory-based standards with nutrientbased standards. These possibilities provide the impetus and focus for this research.3 Initially, we focus on the economic function and consequences of commodity grades and describe the current federal grading system for fruits and vegetables. From this description, we generate some generic components of the current federal grade standards and discuss the potential for adding nutrient attributes and the relationship between sensory and nutrient attributes. We conclude by evaluating the feasibility of a nutrient-based grading standard for fruits and vegetables.

description: Government commodity grading systems have a long and sometimes controversial history in the livestock and meat industry. Historically, the only way to develop standard procedures for a very independent and fragmented group of producers and processors has been to utilize the auspices of government. Originally, the primary reason for government grading systems was to facilitate (1) more accurate identification of value-related differences in commodities being marketed for both buyers and sellers, (2) an improved competitive process, and (3) improved resource allocation (producing the "right" products) in the industry. The government grading system in the beef industry has been a frequent subject of controversy and, infrequently, changed in the last 30 years, while the pork government grading system has fallen into disuse. In this paper, we focus primarily on the pork industry grading system, its history, alternative criteria and grading approaches, and offer some recommendations. Then we discuss some related issues regarding the beef grading system and consider possible changes.

description: The roots of situation and outlook (S&O) analysis run deep in the U.S. Department of Agriculture (USDA). Last year marked the 71st anniversary of the founding of the Bureau of Agricultural Economics and the 70th anniversary of USDA's first Outlook Conference. And the statistical work on which outlook analysis is based goes back more than 130 years. Not surprisingly, outlook work has changed over time as American agriculture and its place in the economy and rural America have evolved. USDA's S&O program is at a turning point and will be changing markedly in coming years.

description: Valley pseudospin in two-dimensional (2D) transition-metal dichalcogenides (TMDs) allows optical control of spin-valley polarization and intervalley quantum coherence. Defect states in TMDs give rise to new exciton features and theoretically exhibit spin-valley polarization; however, experimental achievement of this phenomenon remains challenges. Here, we report unambiguous valley pseudospin of defect-bound localized excitons in CVD-grown monolayer MoS2; enhanced valley Zeeman splitting with an effective g-factor of -6.2 is observed. Our results reveal that all five d-orbitals and the increased effective electron mass contribute to the band shift of defect states, demonstrating a new physics of the magnetic responses of defect-bound localized excitons, strikingly different from that of A excitons. Our work paves the way for the manipulation of the spin-valley degrees of freedom through defects toward valleytronic devices.

DIAGNOSIS: Fourth and fifth metasomal segments ventrally without carinae and deeply punctate. Spaces among punctae smooth and without hairs. Dorsal surface of all metasomal segments bears conspicuous pointed granules arranged in median belt with wider anterior and posterior ends. First to third metasomal segments yellow to yellowish brown, fourth and fifth segments black. Legs mostly yellow, only femur may bear dark spots. Movable fingers bear 8 or 9 rows of granules that have internal and external granules and 4 distal granules. Tarsomere I of first to third legs with bristlecombs, tarsomere I of fourth legs without bristlecombs.
COMMENTS. The lectotype is being designated in order to stabilize the nomenclature. Fet & Lowe (2000: 194) consider a female No. 1896.9.26.10 to be the holotype, but Pocock (1897: 109) listed a female and a male and did not designate one of them as the holotype.
DISTRIBUTION. India (Pocock, 1897: 109; Tikader & Bastawade, 1983: 124). This species is listed also from Afghanistan and Pakistan (Levy & Amitai, 1980: 94), but these records need to be further verified.

description: We present a first calculation of the rate for plasmon production in semiconductors from nuclei recoiling against dark matter. The process is analogous to bremsstrahlung of transverse photon modes, but with a longitudinal plasmon mode emitted instead. For dark matter in the 10 MeV - 1 GeV mass range, we find that the plasmon bremsstrahlung rate is 4-5 orders of magnitude smaller than that for elastic scattering, but 4-5 orders of magnitude larger than the transverse bremsstrahlung rate. Because the plasmon can decay into electronic excitations and has characteristic energy given by the plasma frequency $ω_p$, with $ω_p \approx 16$ eV in Si crystals, plasmon production provides a distinctive signature and new method to detect nuclear recoils from sub-GeV dark matter.

description: A theoretical many-body analysis is presented of the electron-electron inelastic lifetimes of Shockley electrons and holes at the (111) surface of Cu. For a description of the decay of Shockley states both below and above the Fermi level, single-particle wave functions have been obtained by solving the Schrödinger equation with the use of an approximate one-dimensional pseudopotential fitted to reproduce the correct bulk energy bands and surface-state dispersion. A comparison with previous calculations and experiment indicates that inelastic lifetimes are very sensitive to the actual shape of the surface-state single-particle orbitals beyond the $\barΓ$ (${\bf k}_\parallel=0$) point, which controls the coupling between the Shockley electrons and holes.

Are private universities exempt from student concerns about textbook costs? a survey of students at American University

description: A survey conducted in the fall of 2015 at American University in Washington, DC shows that rising textbook prices similarly affect students at an expensive private university as those at community colleges and state schools. Research on high textbook costs that has demonstrated corollary unwanted behavior changes in students, including not purchasing the book, resorting to illegal online downloads, and poor study habits, were confirmed at American University as well. Solutions that have been proposed to this problem of prohibitive textbook prices, including Open Educational Resources (OER), could have an equally profound impact at American University, and potentially similar private universities, as has been demonstrated at less selective and more affordable counterparts.

We generalize the above result: if these minimal representing geodesic loops of $π_1(M,x)$ escape from any bounded metric balls at a sublinear rate with respect to their lengths, then $π_1(M,x)$ is virtually abelian.

description: Many compactifications of higher-dimensional supersymmetric theories have approximate vacuum degeneracy. The associated moduli fields are stabilized by non-perturbative effects which break supersymmetry. We show that at finite temperature the effective potential of the dilaton acquires a negative linear term. This destabilizes all moduli fields at sufficiently high temperature. We compute the corresponding critical temperature which is determined by the scale of supersymmetry breaking, the beta-function associated with gaugino condensation and the curvature of the K"ahler potential, T_crit ~ (m_3/2 M_P)^(1/2) (3/β)^(3/4) (K'')^(-1/4). For realistic models we find T_crit ~ 10^11-10^12 GeV, which provides an upper bound on the temperature of the early universe. In contrast to other cosmological constraints, this upper bound cannot be circumvented by late-time entropy production.

description: Veterinarians practicing equine medicine account for less than five percent of the veterinary profession. Within the equine practice, the rate of young veterinary practitioners leaving the equine veterinary profession has increased over the past ten years. What is driving equine practitioners to leave the equine veterinary sector and pursue work in other veterinary sectors, private or public, is unknown. Using the 2016 American Veterinary Medical Association/American Association of Equine Practitioners Survey of Equine Practitioners, a binary logit model is utilized to analyze factors that affect an equine practitioner's desire to change veterinary sectors. Preliminary analysis shows that a decrease in satisfaction with their work environment, high student debt, and lower income compared to other veterinary sectors, increase the odds of an equine practitioner desiring to leave equine medicine. These results are then compared to the overall veterinary profession. By understanding what drives an equine practitioner to leave equine medicine, proper tools can be put in place in order to help retain, and bring in new equine practitioners.
title: Predicting chemical effects on birds: a critical literature review.
Creators: name: Howe, Paul D
Publisher: name: The Open University

description: The effects of chemicals on birds has created a great deal of public concern and scientific debate. A wealth of information on species distribution, breeding numbers and population changes has provided a good basis for identifying environmental problems after the event. However, the difficulty lies in using such information for predicting possible chemical impacts in the future. Standard laboratory toxicity testing is carried out as a routine requirement for both national and international regulatory authorities, and the prediction of effects is still centred around these tests. .Development work has concentrated on test regimes and field validation, but little attention has been focused on the interpretation of the data in the light of the other factors which influence the survival and reproduction of wild birds. Standard and non standard tests, field trials, monitoring and risk assessment methods and approaches are reviewed. It is concluded that laboratory testing has an important place in the prediction of the effects of chemicals on wild bird populations. However, such tests must be seen merely as a means of screening chemicals for potential effects rather than realistic models of events in the natural world. Test design needs to be varied, .and risk assessment flexible, with significant scope for expert judgement. Risk assessment of chemicals should be fate-led to minimize the unnecessary use of laboratory animals by identifying the distribution and availability of chemicals in the environment before testing for effects. Preliminary risk assessment conclusions should be validated in the field. Multidisciplinary studies involving testing, field trials, monitoring and risk assessment should ideally be carried out; disciplines such as toxicology, environmental chemistry, ecology, population dynamics, ethology, physiology and land use geography all have a part to play.

description: We report the discovery of VMC J021140.41-735320.4, a faint ($J=19.9$ mag) and extremely red ($J-K_s=3.0$ mag, $W1-W2=0.45$ mag, $J-W2=4.7$ mag) high proper motion object in front of the Magellanic Bridge region. It is even redder in the near-infrared than the reddest L7 dwarfs ($J-K_s \gtrsim 2.8$ mag) found in the survey of Schneider et al. (2017) and its colours do also not match exactly those of other peculiar red L7.5 dwarfs. Therefore, we consider its photometric distance estimate of about 73 pc as uncertain. A preliminary combined proper motion and parallax solution involving 20 epochs from the Visible and Infrared Survey Telescope for Astronomy (VISTA) survey of the Magellanic Clouds (VMC), the VISTA hemisphere survey (VHS), and the Wide-field Infrared Survey Explorer (WISE) yields $μ_α\cosδ=+74.3\pm3.4$ mas/yr, $μ_δ=+22.3\pm3.4$ mas/yr, and $π=21.0\pm7.1$ mas. Applying the BANYAN tool (http://www.exoplanetes.umontreal.ca/banyan/) to these results we find a $\approx$68% membership probability of this object in the AB Doradus young moving group (YMG). With its trignometric distance of $\approx$48 pc, VMC J021140.41-735320.4 has a similar absolute magnitude of $M_{K_s}\approx13.4$ mag as the planetary mass companion of another AB Doradus YMG member candidate, 2MASS J22362452+4751425. Follow-up classification spectroscopy and astrometric monitoring are recommended.

Year: 2012

description: The UBC Student Union Building (SUB) is an ongoing project to replace the current SUB with a facility that aims to showcase the highest levels of sustainable building design. Through innovative Student-Driven Decision-Making Processes, the students of university courses such as APSC 261 is able to contribute to the development of the facility. This paper summarizes the research and decision behind installing a display board in the Atrium of the SUB. The display is to bring attention and information to the building occupants about sustainability and features of the building as well as provide general information on events and schedules. This research analyzes the hardware, location, and content of the display board to propose an optimal solution for the stakeholders and end users. A triple bottom line assessment will consider social, ecological, and environmental impacts of the display board on the sustainability agenda. The major criteria used to make decisions on this project was that the display had to have the cheapest purchase and operation cost throughout its lifetime. The display should also have lower negative impacts on the environment not only in manufacturing, but also in transportation and use compared to other technologies. For these reasons the LED backlit LCD display was recommended for use in the SUB Atrium. Displayed content was proposed based a survey on the public to gauge the forms of visual media that would be most attractive to the people in the SUB. It was determined that the most effective content would be facts about the new sustainable technology that is being used in the SUB and tips on how to reduce individuals environmental footprint. It was also decided that the most effective locations to place the displays to engage the public is in areas like food courts where they may be viewed while waiting in line or eating.

description: This policy note underscores that while Philippine marine ecosystems are among the world's richest in life forms and of high socioeconomic importance to Filipinos, these are highly threatened. Among the most serious threats are the combinations of overfishing; illegal, unreported, and unregulated fishing; habitat destruction; increased demand for fisheries; and climate change. Probably the most serious threat is the “policy blindness” of the country to its vast and rich ecosystem services. Three policy actions are then proposed, effectively urging for national policies and regulations that will heighten the protection and security of all Philippine terrestrial and aquatic life forms and their genetic information from internal and external threats.

description: This paper measures the multidimensional poverty situation of farm and herder households located in the Tibetan areas of Gansu Province in China by using the Alkire-Foster method. Twelve indicators are included in the multidimensional poverty indicator system, and six different methods are used to calculate the weight of each indicator. Results indicate the adult family members received formal education (x3), the labor availability (x2), the home toilet type (x7), the self-health assessment (x1), and the school-age children drop out (x4) are the major determinants of poverty.

description: Chemical doping is one of the most important strategies for tuning electrical properties of semiconductors, particularly thermoelectric materials. Generally, the main role of chemical doping lies in optimizing the carrier concentration, but there can potentially be other important effects. Here, we show that chemical doping plays multiple roles for both electron and phonon transport properties in half-Heusler thermoelectric materials. With ZrNiSn-based half-Heusler materials as an example, we use high-quality single and polycrystalline crystals, various probes, including electrical transport measurements, inelastic neutron scattering measurement, and first-principles calculations, to investigate the underlying electron-phonon interaction. We find that chemical doping brings strong screening effects to ionized impurities, grain boundary, and polar optical phonon scattering, but has negligible influence on lattice thermal conductivity. Furthermore, it is possible to establish a carrier scattering phase diagram, which can be used to select reasonable strategies for optimization of the thermoelectric performance.

Are private universities exempt from student concerns about textbook costs? a survey of students at American University

description: A survey conducted in the fall of 2015 at American University in Washington, DC shows that rising textbook prices similarly affect students at an expensive private university as those at community colleges and state schools. Research on high textbook costs that has demonstrated corollary unwanted behavior changes in students, including not purchasing the book, resorting to illegal online downloads, and poor study habits, were confirmed at American University as well. Solutions that have been proposed to this problem of prohibitive textbook prices, including Open Educational Resources (OER), could have an equally profound impact at American University, and potentially similar private universities, as has been demonstrated at less selective and more affordable counterparts.
Cosmological perturbations through a simple bounce

description: We present a detailed study of a simple scalar field model that yields non-singular cosmological solutions. We study both the qualitative dynamics of the homogeneous and isotropic background and the evolution of inhomogeneous linear perturbations. We calculate the spectrum of perturbations generated on super-Hubble scales during the collapse phase from initial vacuum fluctuations on small scales and then evolve these numerically through the bounce. We show there is a gauge in which perturbations remain well-defined and small throughout the bounce, even though perturbations in other commonly used gauges become large or ill-defined. We show that the comoving curvature perturbation calculated during the collapse phase provides a good estimate of the resulting large scale adiabatic perturbation in the expanding phase while the Bardeen metric potential is dominated by what becomes a decaying mode after the bounce. We show that a power-law collapse phase with scale factor proportional to $(-t)^{2/3}$ can yield a scale-invariant spectrum of adiabatic scalar perturbations in the expanding phase, but the amplitude of tensor perturbations places important constraints on the allowed initial conditions.

description: Pecan trees can be found across much of the southern United States, and further, the pecan is the only major cultivated nut native to the United States. Pecans also provide promising profit potential for producers with the right conditions. Cattle and pecan trees often coexist across the southern United States, and silvopastoralism (agroforestry) has been shown to be mutually beneficial in some cases. Yet, the value that cattle add to a pecan production system is still unknown. The objective of this paper is to determine the value (cost savings or ancillary benefits) of this silvopastoral system and under what conditions cattle may not be complementary to the pecan production system. An income model will be used for this analysis. It provides a 10-year analysis for production and input and output prices; the firm’s annual income statement, cash flow, and balance sheet are calculated, as well as annual debt servicing costs on capital expenses and replacement and financing of machinery over time. Further, it estimates annual federal income taxes, along with costs from cash flow deficit financing. Results will indicate under what conditions this silvopastoral system is mutually beneficial and identify what factors influence whether these two enterprises can coexist.
