description: Due to growth and changing distribution channels for organic food in Germany, there is some concern that organic food will lose against local food in the competition for conscious consumers. In this paper we will present the results of a survey in Bavaria searching for consumer motives and label recognition. A choice experiment using different prices, brands and labels is conducted for bread, beer and milk. Results show the importance of local production to the surveyed consumers, similarly for conventional as for organic products.

description: Snap bean (Phaseolus vulgaris L.) is low in fat and high in nutrients; however, it also contains toxigenic factors such as phytohemagglutinin (PHA), which is poisonous to humans. Here, we aimed to determine the distribution of PHA in natural populations of snap bean by analyzing a candidate gene (PHA-E) related to PHA content. Functional genome-wide single nucleotide polymorphisms (SNPs) were then scanned to identify SNPs related to PHA content. A total of 150 snap bean varieties were examined. PHA content and PHA-E expression levels were determined 10, 14, 18, 22, 26 and 30 days after anthesis. Then, association analyses were carried out to identify causal SNPs in PHA-E via genotyping and association tests. PHA-E expression was positively-correlated with PHA content. Among 59 detected SNPs, the ratio of synonymous to nonsynonymous changes was 1:8. P190 was identified as a novel SNP associated with PHA content. The allele carrying the GG genotype at P190 was detected in 130 varieties, of which 86 had an above-average PHA content, while the allele carrying the AA genotype at P190 was detected in 20 varieties, of which 17 (85%) had a low PHA content. Analyses of the PHA content and gene expression in fresh pods of 150 snap bean cultivars revealed population-level distribution and genetic variation, providing a unique measure for screening of low-level or nontoxic cultivars and aiding future breeding of new cultivars.

description: The axisymmetric five-body problem with the concave configuration has been studied numerically to reveal the basins of convergence, by exploring the Newton-Raphson iterative scheme, corresponding to the coplanar libration points (which act as attractors). In addition, four primaries are set in axisymmetric central configurations introduced by Érdi and Czirják and the motion is governed by mutual gravitational attraction only. The evolution of the positions of libration points is illustrated, as a function of the value of angle parameters. A systematic and rigorous investigation is performed in an effort to unveil how the angle parameters affect the topology of the basins of convergence. In addition, the relation of the domain of basins of convergence with required number of iterations and the corresponding probability distributions are illustrated.

 Differential diagnosis. This new genus is most close to the genus Listropsoralgoides. In males of the both genera, the genital papillae, setae d1 and s III are present, and setae c1 are absent. Males of these genera differ from each other by the following characters. In Didelphialges gen. n., genua III are with the membranous projection, tibiae III are with well developed ventro-antiaxial projection, setae h2 are whip-like (longer than the hysteronotal shield), the spurs on coxal fields I and III are absent. In Listropsoralgoides, the projections on genua III and tibiae III are absent, setae h2 are relatively short (about 3 times shorter than the hysteronotal shield), the spurs on coxal fields I and III is present.
 The new genus differs from the Petauralges by the following characters. In Didelphipsoralges, the ventral median spurs of the subcapitulum are absent, setae se are microsetae, setae h1 are absent, setae e IV are filiform, genua III and tibiae III are with the ventro-paraxial projection, and pretarsi IV are present. In Petauralges, the ventral median spurs of the subcapitulum are present, setae se are long, much longer than si, setae h1 are present, setae e IV are sucker-like, genua III and tibiae III are without projections, and pretarsi IV are absent.
 The new genus differs from Listropsoralges by the presence of the genital papillae and setae d1, s III, and by the absence of setae h1. In Listropsoralges, the genital papillae, setae d1, and s III are absent, and setae h1 are present.

description: We revisit the basic variational formulation of the minimization problem associated with the micromagnetic energy, with an emphasis on the treatment of the stray field contribution to the energy, which is intrinsically non-local. Under minimal assumptions, we establish three distinct variational principles for the stray field energy: a minimax principle involving magnetic scalar potential and two minimization principles involving magnetic vector potential. We then apply our formulations to the dimension reduction problem for thin ferromagnetic shells of arbitrary shapes.

description: This research examines whether environmentally based intervention strategies increase elementary students’ selection of white milk. At intervention school one, white milk was easily accessible, but students had to ask for chocolate milk. As an outcome, students increased their selection of white milk compared to control school students (p≤0.001). At intervention school two, the visual cue of a threefold greater quantity of white compared to chocolate milk did not significantly alter selection patterns. This research indicates that requiring students to ask for an item rather than self-serve can help modify food selections and serve as a tool for obesity prevention.

description: Researchers working in the fields of family studies and psychology show motherchild relationship dynamics affect the occurrence of childhood overweight and obesity. Many of the significant behaviors they identify relate to negotiation and generosity norms in the household. The primary objective of this study is to test the value of altruistic and collective models of household behavior using the dictator and ‘carrotstick’ laboratory experiments. We also test exploratory hypotheses relating mother’s generosity and child’s punitive behavior and mother-child weight and fitness outcomes using dictator and ‘carrot-stick’ games. The data were collected from 50 mother-child pairs in Laramie, Wyoming. The children were all eight to 10 years old. The mother’s completed a survey to measure family attitudes and beliefs around food and fitness. All of the mothers and children completed a fitness assessment and blood draw to measure their cholesterol, triglyceride, and hemoglobin levels in addition to the economic experiments. The data do not support altruistic models of familial utility maximization as suggested by Becker’s Rotten Kid Theorem. We do find children overwhelmingly influence mothers’ allocations to maximize child, not household, welfare or utility. Results also indicate there is a positive relationship between mother generosity for child junk food the child’s waist circumference. Children who demand punitive behavior in the ‘carrot-stick’ game were less fit and more likely to be overweight and obese. The results of this study offer insights into household allocation processes which effect both mother and child weight and health outcomes.

description: A rank-n tensor on a Lorentzian manifold V whose contraction with n arbitrary causal future directed vectors is non-negative is said to have the dominant property. These tensors, up to sign, are called causal tensors, and we determine their general properties in dimension N. We prove that rank-2 tensors which map the null cone on itself are causal. It is known that, to any tensor A on V there is a corresponding ``superenergy'' (s-e) tensor T{A} which always has the dominant property. We prove that, conversely, any symmetric rank-2 tensor with the dominant property can be written in a canonical way as a sum of N s-e tensors of simple forms. We show that the square of any rank-2 s-e tensor is proportional to the metric if N<5, and that this holds for the s-e tensor of any simple form for arbitrary N. Conversely, we prove that any symmetric rank-2 tensor T whose square is proportional to the metric must be, up to sign, the s-e of a simple p-form, and that the trace of T determines the rank p of the form. This generalises, both with respect to N and the rank p, the classical algebraic Rainich conditions, which are necessary and sufficient conditions for a metric to originate in some physical field, and has a geometric interpretation: the set of s-e tensors of simple forms is precisely the set of tensors which preserve the null cone and its time orientation. It also means that all involutory Lorentz transformations (LT) can be represented as s-e tensors of simple forms, and that any rank-2 s-e tensor is the sum of at most N conformally involutory LT. Non-symmetric null cone preserving maps are shown to have a causal symmetric part and are classified according to the null eigenvectors of the skew-symmetric part. We thus obtain a complete classification of all conformal LT and singular null cone preserving maps on V.

description: The Passalidae family is a group of sub social saproxylophagous beetles of pantropical distribution that present two tribes in the Neotropics. They are important in the reincorporation of organic matter in the nutrient cycle and with potential use as ecological indicators. Based on secondary information and material deposited in theEntomological Collection of Universidad Nacional de San Antonio Abad in Cusco, Peru, the list of species of the family in Peru was made. The record includes 61 speciesdistributed in 6 genera (Passalus Fabricius, Paxillus MacLeay, Spasalus Kaup, Verres Kaup, Popilius Kaup and Veturius Kaup), in the Passalini and Proculini tribes, beingPassalus (30 spp.) the most abundant genus and Veturius (17 spp.) the most widely distributed. The records cover 12 departments of the country and 9 biogeographic provinces in an altitudinal range that exceeds 2600 m. The records of the family in Peru are smaller compared to neighboring countries in South and Central America, mainly due to the lack of collection work and systematic studies in the group, which would allow knowing the real diversity of the family in the country, which would allow knowing the real diversity of the family in the country which is probably greater than the diversity currently known.
Disentangling Planets from Photoelectric Instability in Gas-Rich Optically Thin Dusty Disks

description: Structures in circumstellar disks such as gaps and rings are often attributed to planets. This connection has been difficult to show unequivocally, as other processes may also produce these features. Particularly, a photoelectric instability (PEI) has been proposed, operating in gas-rich optically thin disks, that generates structures predicted by planet--disk interactions. We examine the question of how to disentangle planetary effects on disk structure from the effects of the PEI. We use the Pencil Code to perform 2D global hydrodynamical models of the dynamics of gas and dust in a thin disk, with and without planetary perturbers. Photoelectric heating is modeled with an equation of state where pressure is proportional to dust surface density. The drag force on grains and its backreaction on the gas are included. Analyzing the situation without PEI, we find that gas--dust interactions alter the shape of the planetary gap from the dust-free case when the local dust-to-gas ratio $\varepsilon$ approaches unity. This result applies also to primordial disks, because dust drifting inwards accumulates at the edge of the planetary gap, and any initial dust-to-gas ratio eventually achieves $\varepsilon=1$ if the dust reservoir is sufficient. We find a result particular to high dust-to-gas ratio disks as well: as dust drifts inwards, the dust front becomes a sharp transition, and the backreaction triggers the Rossby wave instability. When PEI is included, we find that it obscures structures induced by planets unless the planet's mass is sufficiently large to carve a noticeable gap. Specifically, the instability generates arcs and rings of regular spacing: a planet is discernible when it carves a dust gap wider than the wavelength of the PEI.

description: Proteus mirabilis is a gram-negative bacterium particularly known for its unique swarming ability. The swarming gives the bacteria ability to enhance adherence to the catheter surface and epithelium cells of the urethra to cause catheter associated urinary tract infections. P. mirabilis has evolved resistant to antibiotics. Additionally, there is an approved vaccine against P. mirabilis, thus demanding for identification of new vaccine targets. This gram-negative bacterium consists of 19,502 core proteins, out of which 19,063 are redundant proteins and remaining 439 are non-redundant proteins. The non-redundant proteins have 21 proteins present on the cell surface out of which 11 proteins are virulent. Antigenicity analysis predicted only 2 proteins as antigenic (fimbrial biogenesis outer membrane usher protein and ligand-gated channel protein). Four and seven B-cells epitopes were predicted from the former and later proteins, respectively. The predicted B-cells epitopes were used for T- cells epitopes prediction. The predicted epitopes were linked to each other through GPGPG linkers and joined with cholera toxin beta subunit adjuvant. A multi-epitopes vaccine construct consisting of 226 residues was docked with MHC-I, MHC-II and TLR-4. The best docked complex in each case has binding energy of −714.6, −744.6 and −829.5 kcal/mol, respectively. Moreover, the docking results were validated through molecular dynamics simulation and binding free energies estimation. The net energy of −137.2 kcal/mol was calculated for vaccine-MHC-I complex, −133.39 kcal/mol for vaccine-MHC-II and −158.68 kcal/mol for vaccine-TLR-4 complex. The designed vaccine construct could provoke immune responses against targeted pathogen and may be used in experimental testing. Communicated by Ramaswamy H. Sarma

description: The Majorana zero mode (MZM), which manifests as an exotic neutral excitation in superconductors, is the building block of topological quantum computing. It has recently been found in the vortices of several iron-based superconductors as a zero-bias conductance peak (ZBCP) in tunneling spectroscopy. In particular, a clean and robust MZM has been observed in the cores of free vortices in (Li0.84Fe0.16)OHFeSe. Here using scanning tunneling spectroscopy (STS), we demonstrate that Majorana-induced resonant Andreev reflection occurs between the STM tip and this zero-bias bound state, and consequently, the conductance at zero bias is quantized as 2e2/h. Our results present a hallmark signature of the MZM in the vortex of an intrinsic topological superconductor, together with its intriguing behavior.

description: China underwent tremendous agricultural market reforms in the 1990s prior to its accession to the WTO, drastically decreasing domestic market distortions. We ask whether these reforms have led to agricultural commercialization and have improved the welfare of rural Chinese households measured by household average share of calories from non-staples. We identify the effect of local market liberalization by calculating the degree to which local markets reflect world prices. We find that farmers have commercialized in response to market liberalization and that particularly for food insecure households, commercialization has increased household nutrition. The commercialization of field crops and horticulture increases nutrition while the commercialization of livestock does not.

description: Overall, the study investigated the impact of access to and adoption of extension services and agricultural technology in reducing poverty in Uganda. To meet this objective, the researcher analysed the relationship between poverty and access to agricultural extension services and adoption of agricultural technology. A bivariate and multivariate approach was employed to determine whether access to and adoption of agricultural technology are significant factors in influencing the household poverty in Uganda. The results revealed that there is a significant but weak, relationship between poverty and access to agricultural extension and adoption of agricultural technology, and that poor households have the least access to agricultural extension services and low adoption of agricultural technology. The simulation results showed that improving access to agricultural extension and adoption of agricultural technology result into reduction in probability of being poor. Furthermore, on average access to extension services and adoption of agricultural technology is still very poor among the poor and non-poor Ugandans. High on the priority agenda should be concerted efforts to intensify accessibility to agricultural extension services and adoption of agricultural technology.

description: Animal waste from concentrated animal feeding operations (CAFOs) is a significant contributor to the nitrate contamination of groundwater. Some manures also contain heavy metals and salts that may build up either in cropland or groundwater. To find cost-effective policies for pollution reduction at the farm level, an environmental-economic modeling framework for representative CAFOs is developed, where the owner of the operation is a profit-maximizer subject to environmental regulations. The model incorporates various components such as herd management, manure handling system, crop rotation, water sources, irrigation system, waste disposal options, and pollutant emissions. Decision rules from the optimization problem demonstrate best management practices for CAFOs to improve their economic and environmental performance. Results from policy simulations suggest that direct quantity restrictions of emission or incentive-based emission policies such as a field emission tax are much more cost-effective than the standard approach of limiting the amount of animal waste that may be applied to fields. Furthermore, incentive-based emission policies are shown to have advantages over direct quantity restrictions under certain conditions. We also demonstrate the importance of taking into account the integrated effects of water, nitrogen, and salinity on crop yield and nitrate leaching as well as the spatial heterogeneity of nitrogen/water application when designing policy mechanisms.

description: In the present work, the overall nonlinear elastic behavior of a 1D multi-modular structure incorporating possible imperfections at the discrete (micro-scale) level, is derived with respect to both tensile and compressive applied loads. The model is built up through the repetition of n units, each one comprising two rigid rods having equal lengths, linked by means of pointwise constraints capable to elastically limit motions in terms of relative translations (sliders) and rotations (hinges). The mechanical response of the structure is analyzed by varying the number n of the elemental moduli, as well as in the limit case of infinite number of infinitesimal constituents, in light of the theory of (first order) Structured Deformations (SDs), that interprets the deformation of any continuum body as the projection, at the macroscopic scale, of geometrical changes occurring at the level of its sub-macroscopic elements. In this way, a wide family of nonlinear elastic behaviors is generated by tuning internal microstructural parameters, the tensile buckling and the classical Euler Elastica under compressive loads resulting as special cases in the so-called continuum limit, say when n tends to 1. Finally, by plotting the results in terms of first Piola-Kirchhoff stress versus macroscopic stretch, it is for the first time demonstrated that such SDs-based 1D models can be helpfully used to generalize some standard hyperelastic behaviors by additionally taking into account instability phenomena and concealed defects.

description: This study uses an agricultural household model to examine the tradeoff between farm profitability and a household head’s desire for market work. The theoretical analysis is a comparative statics analysis relative to the two variables. Results show that the tradeoff can arise for non-participants in the labor market under plausible conditions and that the desire for market work has no effect on farm profitability for participants in the labor market. The empirical analysis derives simultaneous equations of the two variables. These equations reveal exclusion restrictions on specific exogenous variables and “local separability” of the model in the equation of farm profitability. Estimation results for Chinese farm households in 2002 verify the tradeoff for the Western region, although it is not found for the other regions. The results are also used to demonstrate the plausibility of the model under “local separability” compared with that under “global separability.”

description: We analyze an interplay between the proximity effect and quantum interference of electrons in hybrid structures superconductor-normal metal-superconductor which contain several insulating barriers. We demonstrate that the dc Josephson current in these structures may change qualitatively due to quantum interference of electrons scattered at different interfaces. In junctions with few conducting channels mesoscopic fluctuations of the supercurrent are significant and its amplitude can be strongly enhanced due to resonant effects. In the many channel limit averaging over the scattering phase effectively suppresses interference effects for systems with {\it two} insulating barriers. In that case a standard quasiclassical approach describing scattering at interfaces by means of Zaitsev boundary conditions allows to reproduce the correct results. However, in systems with {\it three} or more barriers the latter approach fails even in the many channel limit. In such systems interference effects remain important in this limit as well. For short junctions these effects result in additional suppression of the Josephson critical current indicating the tendency of the system towards localization. For relatively long junctions interference effects may -- on the contrary -- enhance the supercurrent with respect to the case of independent barriers.

description: Improvement in maternal health care is at the center stage of policy making for many developing countries including India, which is faced with a high maternal mortality rate of 540 deaths per 100,000 live births. In India, 36% of women are underweight and an important policy question is whether maternal health care has any effect on the longterm health of mothers. In this paper, we investigate whether place of delivery (delivery at health care facility versus delivery at home) has any effect on the body mass index of women and children. This relationship is estimated in the context of Bihar, India where only one in five births take place at a health facility. Data on Bihar is taken from the third round of National Family Health Survey conducted in 2005-2006. The data set contains information on women aged between 15 to 49 years and children below the age of 5. We use the program evaluation approach to estimate the treatment effects associated with deliveries at health care institutions for women. Propensity score matching is used to estimate the average treatment effect on the treated (ATT). For underweight women, we find that ATT is positive and highly significant. This implies that there are average gains from delivering at a health facility as compared to delivering at home for underweight women. Using the propensity score results we find that education, urbanization, and higher household wealth increase the likelihood of using health institutions for child deliveries. Therefore, we recommend that (i) awareness should be spread about the positive health impacts of institutional deliveries though educational programs, (ii) there is a need for more investment in health infrastructure in Bihar, and (iii) maternal health care should be made accessible and affordable to poor households.

description: The Australian organic industry has undergone recent and rapid expansion in response to growing consumer concern over food safety issues. The industry is growing at 20- 30% per annum and has an annual gross value of $200 million. The Australian organic industry is vehemently opposed to the genetic engineering of foods and has requested that the Australian Government impose a five-year freeze on the import, sale and production of genetically engineered foods. In contrast, the Queensland Government is seeking to accelerate and nurture competitive bioindustries through the provision of its $270 million Bioindustries Strategy. This paper will examine the recent growth of the Australian organic industry, the potential conflicts between biotechnology and organic industry development and conflicting government policies guiding the expansion of the organic and biotechnology industries.

description: A class of spectral problems with a hidden Lie-algebraic structure is considered. We define a duality transformation which maps the spectrum of one quasi-exactly solvable (QES) periodic potential to that of another QES periodic potential. The self-dual point of this transformation corresponds to the energy-reflection symmetry found previously for certain QES systems. The duality transformation interchanges bands at the bottom (top) of the spectrum of one potential with gaps at the top (bottom) of the spectrum of the other, dual, potential. Thus, the duality transformation provides an exact mapping between the weak coupling (perturbative) and semiclassical (nonperturbative) sectors.

description: Background: Macrosomia at birth is associated with maternal hyperglycemia and leads to subsequent susceptibility to obesity, abnormal glucose metabolism, hypertension, and dyslipidemia in offspring. Epigenetic reprogramming has been reported to be involved in the development of human diseases caused by suboptimal environmental or nutritional factors. The study was aiming to explore epigenetic mechanism influences on macrosomic infants exposed to intrauterine hyperglycemia. We performed a genome-wide analysis of DNA methylation in cord blood from macrosomic infants born to women with gestational diabetes in order to identify genes related to fetal growth or early adipose tissue development. Methods: To analyze the epigenetic patterns in umbilical cord blood in gestational diabetes mellitus (GDM), we collected umbilical cord blood from women with GDM (mean pregestational BMI of 24.4 kg/m2 and mean neonatal birth weight of 4366 g) and normal glucose-tolerant women (mean pregestational BMI of 19.8 kg/m2 and mean neonatal birth weight of 3166 g). Differentially methylated genes in the GDM group were identified using the Infinium HumanMethylation450 BeadChip array. Results: A total of 1251 genes were differentially methylated compared to the controls (p < .01). The methylation microarray data showed that two specific CpG sites (cg12604331 and cg08480098) in the gene body of ARHGEF11 were significantly hypomethylated in the cord blood in macrosomic infants. Altered DNA methylation levels of ARHGEF11 were negatively correlated with glucose levels and neonatal birth weight. Conclusions: Exposure to adverse intrauterine environments can alter fetal development, such as by affecting the nutritional status of the fetus. Such exposure can also result in significant epigenetic modifications, including DNA methylation, which could serve as a potential marker for nutrition and metabolic conditions at the neonatal stage or even in the adult.

description: This paper examines changes in the allocation of public funds between production related public goods (PRPGs) and labour augmenting public goods (LAPGs) once elected village leaders replaced an appointment system. We derive a two-period theoretical model in which the interest of appointed leaders in short economic development leads to allocate all public resources into PRPGs in the first period. In contrast, elected leaders have greater incentives to reflect the interest of electorates by allocating public resources to maximize their two-period revenues. The model predicts that elections lead to an increase in the provision level of LAPGs and a decrease in PRPGs in the first period, if the first-period allocation equilibrium of appointed leaders is away from the allocation mix in maximization of the two-period revenues. A panel dataset of 71 villages for the period of 1993-2000 is used to examine these two predictions. The results show that the elections increased the provision level of public health (LAPGs), but had no effects on irrigation facilities and paved roads (PRPGs).

description: We address the problem of identifying the (nonstationary) quantum systems that admit supersymmetric dynamical invariants. In particular, we give a general expression for the bosonic and fermionic partner Hamiltonians. Due to the supersymmetric nature of the dynamical invariant the solutions of the time-dependent Schrödinger equation for the partner Hamiltonians can be easily mapped to one another. We use this observation to obtain a class of exactly solvable time-dependent Schrödinger equations. As applications of our method, we construct classes of exactly solvable time-dependent generalized harmonic oscillators and spin Hamiltonians.
