description: Decision-making is a crucial component of farm management. Farmers may choose to cede decision-making to others inside or outside their businesses (as specialists, contractors or consultants). However, their decision-making may be [or may feel] usurped against their will. This Paper explores Farmer Managerial Sovereignty (FMS). FMS is about the extent to which decision-making is freely and flexibly in the hands of practical farmers and farm managers at farm level rather than with bureaucrats, policymakers, the suppliers of their inputs and/or the buyers of their outputs. This paper explores whether or not FMS has changed over the past two decades, and if so, how? Do farmers/farm managers in Kenya feel more or less change in FMS over these past two decades than those in the UK or vice versa? Two somewhat eclectic samples of 24 contrasting farmers/farm managers from Kenya and 24 from the UK were asked to provide indicative responses: Kenyan farmers felt FMS only lessening somewhat, notably due to increased government bureaucracy and public scrutiny. The UK sample aggregate FMS score indicated a much lessened to lessened overall FMS during the past two decades, especially due to increasing environmental rules, pesticide limitations, increased government bureaucracy and public scrutiny.

description: New farm consultants can be expensive to train, both financially and in terms of the time required. The aim for new consultants is to develop a â€˜full bookâ€™ of clients to become economically viable as quickly as possible. While research into farm consultancy processes can assist with training, trainees also need to develop expertise in farm consultancy. A case study of a consultant with four yearsâ€™ experience was conducted to gather information on the training of farm consultants. This paper reports on the consultants development of professional expertise and aâ€˜full bookâ€™of clients. The study found that there was an emphasis on â€˜learning-by- doingâ€™. Developing expertise involved progressing from simpler to more complex problems and farming systems. This occurred while moving from supervised work to working with farmer groups and project work, before working independently with clients. The reputation of both the consultancy firm and the trainee and the traineeâ€™s social capital, within and outside the firm, were critical to building a client base. This study has made explicit the process of developing professional expertise, including key factors in building a client base, which maybe valuable for other trainee farm consultants and their firms.

description: We study baryons as Skyrmions in holographic QCD with D4/D8/D8-bar multi-D brane system in type IIA superstring theory, and also in the non-linear sigma model with hidden local symmetry (HLS). Comparing these two models, we find that the extra-dimension and its nontrivial curvature can largely change the role of (axial) vector mesons for baryons in four-dimensional space-time. In the HLS approach, the rho-meson field as a massive Yang-Mills field has a singular configuration in Skyrmion, which gives a strong repulsion for the baryon as a stabilizer. When a_1 meson is added in this approach, the stability of Skyrmion is lost by the cancellation of rho and a_1 contributions. On the contrary, in holographic QCD, the rho-meson field does not appear as a massive Yang-Mills field due to the extra-dimension and its nontrivial curvature. We show that the rho-meson field has a regular configuration in Skyrmion, which gives a weak attraction for the baryon in holographic QCD. We argue that Skyrmion with pi, rho and a_1 mesons become stable due to the curved extra-dimension and also the presence of the Skyrme term in holographic QCD. From this result, we also discuss the features of our truncated-resonance analysis on baryon properties with pi and rho mesons below the cutoff scale M_KK about 1GeV in holographic QCD, which is compared with other 5D instanton analysis.

description: We report the results of a high-energy multi-instrumental campaign with INTEGRAL, RXTE, and Swift of the recently discovered INTEGRAL source IGR J19294+1816. The Swift/XRT data allow us to refine the position of the source to RA= 19h 29m 55.9s Dec=+18deg 18' 38.4" (+- 3.5"), which in turn permits us to identify a candidate infrared counterpart. The Swift and RXTE spectra are well fitted with absorbed power laws with hard (Gamma ~ 1) photon indices. During the longest Swift observation, we obtained evidence of absorption in true excess to the Galactic value, which may indicate some intrinsic absorption in this source. We detected a strong (P=40%) pulsation at 12.43781 (+-0.00003) s that we interpret as the spin period of a pulsar. All these results, coupled with the possible 117 day orbital period, point to IGR J19294+1816 being an HMXB with a Be companion star. However, while the long-term INTEGRAL/IBIS/ISGRI 18--40 keV light curve shows that the source spends most of its time in an undetectable state, we detect occurrences of short (~2000-3000 s) and intense flares that are more typical of supergiant fast X-ray transients. We therefore cannot make firm conclusions on the type of system, and we discuss the possible implications of IGR J19294+1816 being an SFXT.

description: We use data from the Sloan Digital Sky Survey and visual classifications of morphology from the Galaxy Zoo project to study black hole growth in the nearby Universe (z < 0.05) and to break down the AGN host galaxy population by color, stellar mass and morphology. We find that black hole growth at luminosities L_OIII >1E40 erg/s in early- and late-type galaxies is fundamentally different. AGN host galaxies as a population have a broad range of stellar masses (1E10-1E11 Msun), reside in the green valley of the color-mass diagram and their central black holes have median masses around 1E6.5 Msun. However, by comparing early- and late-type AGN host galaxies to their non-active counterparts, we find several key differences: in early-type galaxies, it is preferentially the galaxies with the least massive black holes that are growing, while late-type galaxies, it is preferentially the most massive}black holes that are growing. The duty cycle of AGN in early-type galaxies is strongly peaked in the green valley below the low-mass end (1E10 Msun) of the red sequence at stellar masses where there is a steady supply of blue cloud progenitors. The duty cycle of AGN in late-type galaxies on the other hand peaks in massive (1E11 Msun) green and red late-types which generally do not have a corresponding blue cloud population of similar mass. At high Eddington ratios (L/L_Edd > 0.1), the only population with a substantial fraction of AGN are the low-mass green valley early-type galaxies. Finally, the Milky Way likely resides in the "sweet spot" on the color-mass diagram where the AGN duty cycle of late-type galaxies is highest. We discuss the implications of these results for our understanding of the role of AGN in the evolution of galaxies

Structural determinants of the canonical Reelin signaling pathway
Creators: name: Turk, Liam S.
Publisher: name: No Publisher Supplied
Year: 2022

description: Reelin is a secreted glycoprotein that has well-characterized roles in the developing brain. This ~400 kDa protein is made of several Reelin repeat domains (RRs), exists as a homodimer, and primarily functions through pathways that are stimulated by its interactions with two lipoprotein receptors, VLDLR and ApoER2. Reelin has a complex degradation profile; proteases cleave the protein at two sites, generating up to five Reelin fragments. Of these, the dimeric central fragment (CF) is necessary and sufficient to induce signaling through VLDLR and ApoER2. A monomeric CF construct retains the capacity to bind to the lipoprotein receptors but does not initiate signal transduction. In this thesis, we describe a method to purify a Reelin heterodimeric construct to use as a tool in addressing this inherent decoupling of binding and signaling; we also present the cryo-ET determined structure of Reelin’s dimeric CF, which is independently confirmed using other biophysical and structural techniques. We use these data to form a model of Reelin pathway activation that is dependent on Reelin’s unique dimeric conformation. Furthermore, we present the 3.0 Å resolution crystal structure of RR8. RR8 is the most C-terminal of the RRs, and it is connected to a highly basic stretch of amino acids, termed the C-terminal region (CTR). Peripheral RRs, such as RR8, and the CTR have been receiving more attention in the Reelin community because of their increasingly acknowledged roles in Reelin’s function, regulation, and interactions with proteins other than VLDLR and ApoER2. We highlight general similarities yet discrete differences between the RR8 structure and other, previously solved, three-dimensional RR structures and present data that suggest that the CTR is an intrinsically disordered region at Reelin’s C-terminus.

description: In order to ensure the future existence of an industry or business, it should be sustainable in terms of environmental stewardship (planet) and economic prosperity (profit). The problem with improving more than one sustainability indicator is that these indicators are often negatively correlated. In order to increase economic prosperity in a cow-calf operation, one should thus aim to increase the output produced by using less natural resources per unit of output while taking society at large into account. The purpose of this study is to evaluate the differences in value addition and feed requirements of seven different beef breeds on the same extensive farming conditions for a cow-calf enterprise by calculating the economic feed consumption. The results show that there are prominent differences between the seven breeds in terms of their respective feed requirements, value addition and economic feed consumption. The Bonsmara was the best breed in terms of economic feed consumption and the Simmentaler the worst. However, when one considers the results in conjunction with the data that were used to perform the analyses, it can be seen that there was a high negative correlation between the economic feed consumption and the weaning percentage of the various breeds. In order to improve the economic feed consumption of beef production, it is recommended that primary cow-calf producers evaluate the reproduction performance of the breed that they are farming with.

description: Convolutional Neural Networks (CNNs) are known for their ability to learn hierarchical structures, naturally developing detectors for objects, and semantic concepts within their deeper layers. Activation maps (AMs) reveal these saliency regions, which are crucial for many Explainable AI (XAI) methods. However, the direct exploitation of raw AMs in CNNs for feature attribution remains underexplored in literature. This work revises Class Activation Map (CAM) methods by introducing the Label-free Activation Map (LaFAM), a streamlined approach utilizing raw AMs for feature attribution without reliance on labels. LaFAM presents an efficient alternative to conventional CAM methods, demonstrating particular effectiveness in saliency map generation for self-supervised learning while maintaining applicability in supervised learning scenarios.
Mechanical strawberry harvesting

Publisher: name: University of British Columbia

description: Total strawberry production in both Canada and the United States has been steadily declining for the past decade. This trend can, to a large extent, be attributed to the increasing cost and difficulty of getting this crop manually harvested. This research, therefore, is directed toward development of a mechanical harvesting system for strawberries. During initial development of any new concept, a system analysis should be undertaken to ensure that excessively complicated problems will not arise unexpectedly and to ensure that redundant research is not undertaken. Such an analysis indicated that the development of a once-over harvesting system is more feasible than the development of a selective harvesting system. The analysis also indicated that system development will require input from engineers, fruit growers, fruit processors and horticulturalists. An attempt is made to allocate appropriate areas of investigation and research to each of these groups. Group interactions are also investigated. To successfully develop the proposed system, one essential step is development of a mechanical picking machine. A design, based on the physical and mechanical properties of the strawberry fruit and plant, was used to build a picking -machine model. This model was field tested and evaluated. Limited field tests indicated that some field preparation for mechanical harvesting is essential and that a vacuum fruit pick up device should be considered to assist machine feeding. Tests indicated, however, that the proposed concept can be used to remove berries from the plant with very little fruit damage.

Our results suggest that weak-linked GBs are characteristic of both cuprates and pnictides because of competing orders, low carrier density, and unconventional pairing symmetry.

description: The postmodern ultra-competitive global marketplace makes it difficult for companies to hold on to customers. This is especially true for industries that are driven by commodity products, and the South African fertilizer industry is not excluded from this statement. It is therefore important that companies not only operate to create loyal customers, but also increase and maintain a high level of engagement with their customers. This study measures customer engagement for a South African fertilizer company. In doing so, the study makes use, firstly, of a proposed customer engagement model, secondly, a customer engagement questionnaire to measure engagement, and thirdly, measuring the reliability of the data. The results show that all the antecedents were regarded as important by the respondents, and all but one exceed the required 75% level of excellence. The data were tested for reliability and showed excellent reliability in excess of 0.90, as measured by Cronbach alpha. This model can be used by manager, future researchers in the fertilizer industry, as well as other agriculture related industries.

Unconventional approaches to C-H bond activation and alkane functionalization by PCP pincer iridium complexes
Creators: name: Shada, Arun Dixith Reddy
Publisher: name: No Publisher Supplied
Year: 2021

description: This thesis is organized into three themes: (1) C-H bond activation and functionalization studies by PCP type pincer ligated iridium acetate hydride complexes, (2) Investigating the reactivity of four-coordinate (pincer)Ir(CO) complexes toward alkane hydrocarbonylation reactions, and (3) Protons coupled electrons transfer driven alkane dehydrogenation using iridium-pincer complexes.In the first part of this thesis, we describe the preparation of a novel class of PCP-type pincer iridium complexes with acetate ligands. We examined the catalytic activity of (pincer)Ir(OAc)(H) towards transfer and acceptorless dehydrogenation of alkanes. We have studied Lewis Acid’s role in the reactivity of (pincer)Ir(OAc)(H) towards alkene by studying the alkene insertion into iridium hydride bond. We have shown intramolecular C-H bond activations with (pincer)Ir(OAc)(H) in the presence of oxidants. Finally, comparisons were drawn between PCP and Phebox systems towards alkane C-H bond activations. In the second part of this thesis, we explored the unprecedented carbonylation of alkanes in the presence of four-coordinate (pincer)Ir(CO) complexes. Employing a unique acid-catalyzed route, we showed stoichiometric hydrocarbonylation starting from (tBu4PCP)Ir(Et)(CO)(H) to give n-propanol. Although we did not observe catalytic activity towards alkane hydrocarbonylation, we proposed an alkane carbonylation mechanism and have carried out mechanistic studies. We then demonstrated the first examples of hydroformylation of ethylene using (pincer)Ir(CO) complexes under mild conditions. These reactions were shown to be co-catalyzed in the presence of Lewis Acids.In the last part of this thesis, we described the first example of alkane dehydrogenation by proton-coupled electron transfer using (pincer)Ir complexes and a pair of oxidants and bases. Employing silver salts as oxidants and t-butoxide as a base, we have shown dehydrogenation of cyclooctane with (tBu4PCP)Ir(H)2 complex. Up to 97% yield was achieved with respect to oxidant and base, and up to 15 catalytic turnovers with respect to iridium, using t-butoxide as base coupled with various oxidants. Mechanistic studies revealed that oxidants and bases generate the active Ir(I), which dehydrogenate alkanes.

= Myeza Walker, 1863 b: 190. Type species: Myeza tonsalis Walker, 1863
DIAGNOSIS
The Palaearctic fauna of Eschata was revised by Błeszyński (1965). Forewings are shiny snow white, generally with one postmedian and one subterminal line (pers. obs.). Male genitalia with the following characteristics: parrot-beak shaped uncus and beak-shaped gnathos; valva with costal arm; sacculus not marked; juxta notched or bifid as in other Chiloini (Léger et al., 2019; pers. obs.); vesica often with patch of short cornuti. Female genitalia are characterized as follows: papillae anales large, coalesced ventrally and dorsally; posterior apophyses roughly as long as length of tergite VIII; anterior apophyses roughly twice as long as length of tergite VIII; antrum membranous; posterior half of ductus sclerotized as in Chilo species; corpus bursae often with one signum.
DISTRIBUTION
Known from the Oriental region. One species, Eschata sp. cf. rififi Błeszyński, 1965, is reported here from the Philippines.
PHYLOGENETIC RELATIONSHIPS
Although the genus was not included in the molecular phylogeny of Léger et al. (2019), it can be confidently placed in the Chiloini based on the bifid juxta in male genitalia as well as the thick venulae secundae on the tympanal organs.

description: What China wants has profound implications for the export income generated from New Zealand and Australiaâ€™s agrifood sectors. A better understanding of â€˜down underâ€™ advantages in accessing the Chinese market, what this market demands, and how Chinese people go about business will benefit these farming sectors. Employing qualitative empirical research, assisted by academic and industry literature, together with our own ongoing industry networks, this article addresses the question â€œwhat does China want from farming â€˜down underâ€™ in New Zealand and Australia?â€ The greatest advantage of these â€˜down underâ€™ nations lies within our production and supply chain systems which enable us to supply safe and high-quality food products that Chinese consumers demand. In order to fully utilise this advantage, farmers need to integrate themselves within supply chains, which have necessary knowhow in accessing the Chinese market. This knowhow starts with understanding the importance of, and length of time that it takes to build, trusting guanxi (å…³ç³», relationships). Following this understanding, there is a need to appreciate the roles that Key Opinion Leaders (KOLs), daigou and mianzi (é¢å­, â€˜faceâ€™ or prestige) play within the nuances of reaching Chinese consumers and dealing with Chinese agrifood business people.

We present an investigation based on the Infrared Flux Method aimed at assessing the source of such discrepancies and pin down their origin. We break the impasse among different scales by using a large set of solar twins, stars which are spectroscopically and photometrically identical to the Sun, to set the absolute zero point of the effective temperature scale to within few degrees. Our newly calibrated, accurate and precise temperature scale applies to dwarfs and subgiants, from super-solar metallicities to the most metal-poor stars currently known. At solar metallicities our results validate spectroscopic effective temperature scales, whereas for [Fe/H]

description: Energy consumption is an important component in determining the sustainability of farming practices. Identification of dairy farming systems with efficient energy consumption at the same time as minimising greenhouse gas emissions is vital. In this context, it is relevant to assess the energy footprint of different dairy farming systems in order to identify a sustainable dairy system for the future of NZ dairy industry. This research is based on comparative analysis of Pastoral (PDFs) and Barn (BDFs) dairy farming systems in Canterbury, New Zealand. A total of 50 dairy farms were investigated, using direct (fuel, electricity, labour) and indirect (fertilizer, feed supplements, machinery and equipment) energy inputs. The results indicate that PDFs system have 9.5 percent lower energy footprint per hectare than BDFs, mainly due to their greater reliance on pasture based grazing feeding and less use of electricity, fuel and feed supplements. Of interest is that the BDFs use 39% less fertiliser energy but 80% higher feed supplement energy based on the inputs the farmers used. In terms of per kilogram milk solids produced, the PDFs shows 6 % lesser energy footprints compared to BDFs. This research suggests that energy consumption in PDFs in terms of both hectare and milk output is more efficient. However, when considering individual inputs of each system, the energy usage for fertilizer is much higher in PDFs.

description: Each transiting planet discovered is characterized by 7 measurable quantities, that may or may not be linked together (planet mass, radius, orbital period, and star mass, radius, effective temperature, and metallicity). Correlations between planet mass and period, surface gravity and period, planet radius and star temperature have been previously observed among the known transiting giant planets. Two classes of planets have been previously identified based on their Safronov number. We use the CoRoTlux code to compare simulated events to the sample of discovered planets and test the statistical significance of these correlations. We first generate a stellar field with planetary companions based on radial velocity discoveries and a planetary evolution model, then apply a detection criterion that includes both statistical and red noise sources. We compare the yield of our simulated survey with the ensemble of 31 well-characterized giant transiting planets, using a multivariate logistic analysis to assess whether the simulated distribution matches the known transiting planets. Our multivariate analysis shows that our simulated sample and observations are consistent to 76%. The mass vs. period correlation for giant planets first observed with radial velocity holds with transiting planets. Our model naturally explains the correlation between planet surface gravity and period and the one between planet radius and stellar effective temperature. Finally, we are also able to reproduce the previously observed apparent bimodal distribution of Safronov numbers in 10% of our simulated cases, although our model predicts a continuous distribution. This shows that the evidence for the existence of two groups of planets with different intrinsic properties is not statistically significant.

description: This manuscript studies harmonically trapped ideal Bose and Fermi gas systems and their thermodynamics in the framework of the Extended Uncertainty Principle (EUP). In particular, we demonstrated how the ground and thermal particle ratios, condensate temperature, internal energy, specific heat, and equation of state functions change in the EUP formalism. Following a comprehensive analysis, we concluded that the effect of the EUP on ideal Bose and Fermi gas systems remains relatively modest compared to the effect of the Gravitational (Generalised) Uncertainty Principle. { By comparing the obtained results with experimental data, we found that the EUP parameter is bounded as $α\leq 0.36654\times 10^{7}\text{ \ }m^{-2}$.}

description: A viscometer was designed and built to study the rheological behavior of slags over a range of rates of shear of three orders of magnitude, up to a shear stress of [formula omitted]. The following slag compositions were studied (wt.%) 1) 42 Si02 - 20 A12O3 - 38 CaO, 2) 40.3 Si02 - 19.2 Al 2 O3 - 36.5 CaO - 4.0 CaF2, and 3) 37.8 Si02 - 18.0 Al 2 – O3 - 34.2 CaO - 10.0 CaF2, at temperatures of 1) 1390°C - 1350°C - 1332°C, 2) 1325°C - 1300°C and, 3) 1300°C respectively. Newtonian behavior was found for all compositions at the temperatures investigated. General conclusions are drawn as to the likelihood of Newtonian behavior for different compositions in these systems.

description: In this paper, we explore the gravitomagnetic interaction of a black hole (BH) with a misaligned accretion disc to study BH spin precession and alignment jointly with BH mass and spin parameter evolution, under the assumption that the disc is continually fed, in its outer region, by matter with angular momentum fixed on a given direction. We develop an iterative scheme based on the adiabatic approximation to study the BH-disc coevolution: in this approach, the accretion disc transits through a sequence of quasi-steady warped states (Bardeen-Petterson effect) and interacts with the BH until the BH spin aligns with the outer angular momentum direction. For a BH aligning with a co-rotating disc, the fractional increase in mass is typically less than a few percent, while the spin modulus can increase up to a few tens of percent. The alignment timescale is between ~ 100 thousands and ~ 1 millions years for a maximally rotating BH accreting at the Eddington rate. BH-disc alignment from an initially counter-rotating disc tends to be more efficient compared to the specular co-rotating case due to the asymmetry seeded in the Kerr metric: counter-rotating matter carries a larger and opposite angular momentum when crossing the innermost stable orbit, so that the spin modulus decreases faster and so the relative inclination angle.

Structural variation in circular DNA influenced by nucleotide sequence and rotational rigid body parameters
Creators: name: Young, Robert T.
Publisher: name: No Publisher Supplied
Year: 2022

description: The physical configuration of double-stranded DNA plays a significant role in the protection and expression of genetic material. Studies of biologically relevant DNA configurations show the importance of covalently-closed, circular structures with lengths less than one thousand base pairs. Smaller circular forms must contend with thermodynamic barriers, such as differences between bending and torsional properties of DNA, that may prevent them from reaching an energetically stable, low-energy state. An elastic energy minimization study was conducted using a base-pair step harmonic potential function to observe deformations of a set of DNA minicircles. The topoisomers, of length 150 base pairs, vary in both linking number and the nucleotide coding sequence, comprised of equal numbers of the purine nucleotides adenine and guanine. The initial portion of the study focuses on differences between optimized states found with two homopolymeric models that represent B-form DNA. Additional complexity was introduced by using sequence-specific intrinsic states, incorporating differences in the twist and the roll component of the intrinsic bend at AA, AG, GA, and GG dimer steps. Results show connections between optimized energetic states and the uptake of twist of DNA as well as changes in local bend and twist, producing high-energy, out-of-plane deformations of the global structures of circles comprised of specific repeated tracts of adenine and guanine. The structural distortions occur in A₄G₄ and A₅G₅ sequence motifs in the form of either kinked polygonal optimized states or states of out-of-plane bending. The connection between global distortions and sequence found here may be related to effects sequences seen in naturally occurring DNA circles. Further studies of chains made up of other sequence motifs or incorporating more realistic modeling of DNA, such as the known elastic coupling between bend and twist, are needed to establish firm connections between sequence and global DNA structure.

description: The possibility of a hadron-quark phase transition in extreme astrophysical phenomena such as the collapse of a supernova is not discarded by the modern knowledge of the high-energy nuclear and quark-matter equations of state. Both the density and the temperature attainable in such extreme processes are possibly high enough to trigger a chiral phase transition. However, the time scales involved are an important issue. Even if the physical conditions for the phase transition are favorable (for a system in equilibrium), there may not be enough time for the dynamical process of phase conversion to be completed. We analyze the relevant time scales for the phase conversion via thermal nucleation of bubbles of quark matter and compare them to the typical astrophysical time scale, in order to verify the feasibility of the scenario of hadron-quark phase conversion during, for example, the core-collapse of a supernova.

description: A method for calculating the $1/d$ expansion coefficients for solutions of integration by parts relations for Feynman integrals is presented. The idea is to use linear substitutions to transform these relations to an explicitly recursive form. The possibility of such a transformation is demonstrated for several families of massless (with one massive line) vacuum integrals up to the 7-loop level.

description: Within Resonance Chiral Theory and in the context of QCD current correlators at next-to-leading order in 1/N(C), we have analyzed the two-body form factors which include resonances as a final state . The short-distance constraints have been studied. One of the main motivations is the estimation of the chiral low-energy constants at subleading order, that is, keeping full control of the renormalization scale dependence. As an application we show the resonance estimation of some coupling, L(10)(mu_0)=(-4.4 \pm 0.9)10^{-3} and C(87)(mu_0)=(3.1 \pm 1.1)10^{-5}.

description: We find point-like and classical string solutions on the AdS_5 x X^5, where X^5 are the 5-dimensional Sasaki-Einstein manifolds Ypq and Lpqr. The number of acceptable solutions is limited drastically in order to satisfy the constraints on the parameters and coordinates of the manifolds. The energy of the solutions depends on the parameters of the Sasaki-Einstein manifolds and on the conserved momenta transcendentally. A discussion on BPS solutions is presented as well.

description: Society is increasingly putting pressure on producers to behave ethically and sustainably. But, what is the role of retailers in this area? The power of large supermarket retailers is growing at a global level and retailers are now operating as societal gatekeepers; the actions they are taking impact upon both producers and consumers. This paper focuses on a single case study from New Zealand (the removal of caged eggs from supermarkets), to assess whether retailer actions are ethical, sustainable, and beneficial to producers and consumers. Small food producers are particularly vulnerable; this paper concludes by recommending how producers could respond to retailer actions.

description: Forthcoming photometric redshift surveys should provide an accurate probe of the acoustic peak in the two-point galaxy correlation function, in the form of angular clustering of galaxies within a given shell in redshift space. We investigate the form of the anticipated signal, quantifying the distortions that arise due to projection effects, and in particular explore the validity of applying the Limber approximation. A single-integral prescription is presented, which provides an alternative to Limber's equation, and produces a significantly improved prediction in the regime of interest. The position of the acoustic peak within the angular correlation function relates to the angular diameter distance to the far side of the redshift bin. Thicker redshift bins therefore shift comoving features towards smaller angular scales. As a result, the value of the photometric redshift error acquires a greater significance, particularly at lower redshifts. In order to recover the dark energy equation of state to a level of 1%, we find the total redshift dispersion must be determined to within Δσ_z ~ 10^-3, which may prove challenging to achieve in practice.

Hyperfine-interaction- and magnetic-field-induced Bose-Einstein-statistics suppressed two-photon transitions

description: Two-photon transitions between atomic states of total electronic angular momentum $J_a=0$ and $J_b=1$ are forbidden when the photons are of the same energy. This selection rule is analogous to the Landau-Yang theorem in particle physics that forbids decays of vector particle into two photons. It arises because it is impossible to construct a total angular momentum $J_{2γ}=1$ quantum-mechanical state of two photons that is permutation symmetric, as required by Bose-Einstein statistics. In atoms with non-zero nuclear spin, the selection rule can be violated due to hyperfine interactions. Two distinct mechanisms responsible for the hyperfine-induced two-photon transitions are identified, and the hyperfine structure of the induced transitions is evaluated. The selection rule is also relaxed, even for zero-nuclear-spin atoms, by application of an external magnetic field. Once again, there are two similar mechanisms at play: Zeeman splitting of the intermediate-state sublevels, and off-diagonal mixing of states with different total electronic angular momentum in the final state. The present theoretical treatment is relevant to the ongoing experimental search for a possible Bose-Einstein-statistics violation using two-photon transitions in barium, where the hyperfine-induced transitions have been recently observed, and the magnetic-field-induced transitions are being considered both as a possible systematic effect, and as a way to calibrate the measurement.
