description: A limited body of literature suggests complex self-disclosure experiences exist across the career of a Clinical Psychologist. Self-disclosure experiences begin at a doctoral training level within small-group working exercises such as Problem-Based Learning (PBL). Although dilemmas in self-disclosure have been described in PBL, little is known about the processes that underpin them. This research aimed to explore and identify the processes that underpin trainee Clinical Psychologist’s use of self-disclosure within the context of PBL. Semi-structured interviews were conducted with 17 trainee and qualified Clinical Psychologists who had taken part in at least one PBL task as part of their doctoral clinical psychology training. Data was analysed using Constructivist Grounded Theory which resulted in the co-construction of a theoretical model. Participants described navigating an internal disclosure dilemma within PBL. The disclosure dilemma occurred amongst wider contextual factors and disclosure cultures that PBL was positioned within, which led to acts of self-disclosure and non-disclosure. The unique PBL exercise required trainees to balance the task with process factors. Self-disclosure experimentation occurred in relation to different approaches to the task. Responses to self-disclosure influenced the internal disclosure dilemma for future self-disclosure events. The social processes of self-disclosure in PBL contributed to the personal and professional development of the therapist. Therefore, the findings offer important practical implications for trainee Clinical Psychologists about to embark on their initial PBL or self-disclosure experimentation journeys. The findings also highlight significant considerations for doctoral clinical psychology training programmes and the clinical psychology profession to support and facilitate the self-disclosure of trainee and qualified Clinical Psychologists.

description: The ongoing internationalization of markets has become a major issue also for companies of the agribusiness. Nevertheless, neither the degree of internationalization of agribusiness firms nor the internationalization-performance relationship in the agribusiness sector have been analyzed thoroughly so far. To help fill this void, we use panel data compiled from annual reports and balance sheets to investigate the internationalization as well as the internationalization-performance relationship of 21 leading European cooperatives in the dairy and meat sectors. Our results indicate that internationalization has a significant positive impact on firm performance.

description: I present here the characterisation of ultracool dwarfs having been observed through direct, ground-based campaigns. These ultracool dwarfs have been used to assist with the parameterisation of objects as observed by Gaia. I also present software packages and further technical skills, developed for the astronomical community. Data observed from 2015–2016 on the OSIRIS instrument at the GTC was used to measure spectral types and radial velocities for 46 objects. This data was analysed further to ascertain if any objects had interesting features such as young moving group membership or low metallicity features. I led multiple observing proposals and observed on several nights, which resulted in a number of interesting objects being discovered. Expanding on what was known of ultracool dwarfs from direct campaigns, I helped data process the ultracool dwarfs in Gaia data releases. I contributed to ‘downstream’ analysis of these Gaia ultracool dwarfs. This, in turn, enhanced the body-of-knowledge of directly observed ultracool dwarfs. Using Gaia DR3, I created a novel colour ratio to select outliers from Gaia RP spectra. This was a proof-of-concept work to demonstrate that one can use a large, homogeneous population like Gaia, to identify the most extreme outliers from low resolution data. I created multiple software tools and databases, which the community has used to observe, access, analyse and present data.

description: Исследования проводили с целью изучения влияния различных предшественников, включая нетрадиционные, на содержание и расходование влаги, плотность и твердость почвы, формирование почвенной структуры и урожайность озимой пшеницы. Работу выполняли в 2014-2019 гг. в многолетнем стационарном эксперименте, заложенном в Воронежской области. Почва опытного участка - чернозем обыкновенный среднемощный. Перед закладкой эксперимента ее слой 0...40 см характеризовался следующими агрохимическими показателями: содержание гумуса - 6,61 %, общего азота - 0,33 %, фосфора - 0,21 %, калия -1,80 %, сумма поглощенных оснований -57,0 мг-экв./100 г, рН - 6,58 ед Лучшие в опыте условия для использования влаги складывались в вариантах с чистым и сидеральным эспарцетовым паром, а также с эспарцетом на сено. Величина коэффициента водопотребления озимой пшеницей в зернопаропропашном севообороте после этих предшественников составляла соответственно 60,8 м3/т, 56,2 м3/т и 63,1 м3/т, что свидетельствует о близких водозатратах на формирование урожая. В этих же вариантах отмечено наибольшее поступление пожнивно-корневых остатков озимой пшеницы, количество которых находилось в прямой зависимости от урожайности культуры (r = 0,84). Лучшими среди изучаемых предшественников для озимой пшеницы были эспарцет на сидерат и эспарцет на сено, урожайность культуры после которых достигла 4,45 и 4,43 т/га соответственно и находилась на уровне величины этого показателя после чистого пара (4,53 т/га), обеспечивающего формирование зерна с содержанием белка до 12,5 %, клейковины - до 26,4 %.

description: Background: Concurrent variation in adiposity and inflammation suggests potential shared functional pathways and pleiotropic disease underpinning. Yet, exploration of pleiotropy in the context of adiposity-inflammation has been scarce, and none has included self-identified Hispanic/Latino populations. Given the high level of ancestral diversity in Hispanic American population, genetic studies may reveal variants that are infrequent/monomorphic in more homogeneous populations. Methods: Using multi-trait Adaptive Sum of Powered Score (aSPU) method, we examined individual and shared genetic effects underlying inflammatory (CRP) and adiposity-related traits (Body Mass Index [BMI]), and central adiposity (Waist to Hip Ratio [WHR]) in HLA participating in the Population Architecture Using Genomics and Epidemiology (PAGE) cohort (N = 35,871) with replication of effects in the Cameron County Hispanic Cohort (CCHC) which consists of Mexican American individuals. Results: Of the > 16 million SNPs tested, variants representing 7 independent loci were found to illustrate significant association with multiple traits. Two out of 7 variants were replicated at statistically significant level in multi-trait analyses in CCHC. The lead variant on APOE (rs439401) and rs11208712 were found to harbor multi-trait associations with adiposity and inflammation. Conclusions: Results from this study demonstrate the importance of considering pleiotropy for improving our understanding of the etiology of the various metabolic pathways that regulate cardiovascular disease development.

description: The mild form of the Weak Gravity Conjecture states that quantum or higher-derivative corrections should decrease the mass of large extremal charged black holes at fixed charge. This allows extremal black holes to decay, unless protected by a symmetry (such as supersymmetry). We reformulate this conjecture as an integrated condition on the effective stress tensor capturing the effect of quantum or higher-derivative corrections. In addition to charged black holes, we also consider rotating BTZ black holes and show that this condition is satisfied as a consequence of the $c$-theorem, proving a spinning version of the Weak Gravity Conjecture. We also apply our results to a five-dimensional boosted black string with higher-derivative corrections. The boosted black string has a $\text{BTZ}\times S^2$ near-horizon geometry and, after Kaluza-Klein reduction, describes a four-dimensional charged black hole. Combining the spinning and charged Weak Gravity Conjecture we obtain positivity bounds on the five-dimensional Wilson coefficients that are stronger than those obtained from charged black holes alone.

description: В статье рассматриваются проблемы, связанные с отрицательным балансом кальция в почве в результате интенсивного земледелия. Исследования проводили с целью анализа влияния известкования и фосфоритования на агроэкологическое состояние черноземных почв и продуктивность сельскохозяйственных культур, с последующим обоснованием объемов химической мелиорации пахотных земель в условиях Липецкой области. На почвах, имеющих кислую (рН менее 5,5) реакцию среды с низкой (до 50 мг/кг почвы) обеспеченностью подвижным фосфором, целесообразно проведение известкования и фосфоритования, способствующих улучшению физико-химических показателей почвы, увеличению содержания в ней органического вещества, повышению биологической активности почвы, более эффективному использованию органических и минеральных удобрений, что, в свою очередь, повысит урожайность и обеспечит получение значительного экономического эффекта. Из 1183,6 тыс. га обследованной площади пахотных земель сельскохозяйственного назначения в Липецкой области на долю кислых почв с рН ниже 5,5 приходится 918,1 тыс. га. За последние 5 лет в области произвестковано более 100 тыс. га, в том числе в 2018 г. - 25,4 тыс. га, в 2019 г. - 25,8 тыс. га. К 2024 г. в Липецкой области планируется произвестковать более 190 тыс. га, в первую очередь на эти цели необходимо использоватьдефекат. В 2019 г. посевные площади с содержанием фосфора до 50 мг/кг почвы составили 226,4 тыс. га. Поэтому, наряду с раскислением, необходимо проводить фосфоритование почв.

description: While electronic and spectroscopic properties of self-assembled In_{1-x}Ga_{x}As/GaAs dots depend on their shape, height and alloy compositions, these characteristics are often not known accurately from experiment. This creates a difficulty in comparing measured electronic and spectroscopic properties with calculated ones. Since simplified theoretical models (effective mass, k.p, parabolic models) do not fully convey the effects of shape, size and composition on the electronic and spectroscopic properties, we offer to bridge the gap by providing accurately calculated results as a function of the dot height and composition. Prominent results are the following. (i) Regardless of height and composition, the electron levels form shells of nearly degenerate states. In contrast, the hole levels form shells only in flat dots and near the highest hole level (HOMO). (ii) In alloy dots, the electrons' ``s-p'' splitting depends weakly on height, while the ``p-p'' splitting depends non-monotonically. In non-alloyed InAs/GaAs dots, both these splittings depend weakly on height. For holes in alloy dots, the ``s-p'' splitting decreases with increasing height, whereas the ``p-p'' splitting remains nearly unchaged. Shallow, non-alloyed dots have a ``s-p'' splitting of nearly the same magnitude, whereas the ``p-p'' splitting is larger. (iii) As height increases, the ``s'' and ``p'' character of the wavefunction of the HOMO becomes mixed, and so does the heavy- and light-hole character. (iv) In alloy dots, low-lying hole states are localized inside the dot. Remarkably, in non-alloyed InAs/GaAs dots these states become localized at the interface as height increases. This localization is driven by the biaxial strain present in the nanostructure.

description: Let k be an algebraically closed field of characteristic p. Let X(p^e;N) be the curve parameterizing elliptic curves with full level N structure (where p does not divide N) and full level p^e Igusa structure. By modular curve, we mean a quotient of any X(p^e;N) by any subgroup of ((Z/p^e Z)^* x \SL_2(Z/NZ))/{+-1}. We prove that in any sequence of distinct modular curves over k, the k-gonality tends to infinity. This extends earlier work, in which the result was proved for particular sequences of modular curves, such as X_0(N) for p not dividing N. We give an application to the function field analogue of a uniform boundedness statement for the image of Galois on torsion of elliptic curves.

description: Measures of productivity growth are often pro-cyclical. This study focuses on measurement errors in capital inputs, associated with unobserved variations in capital utilization rates, as an explanation for the existence of pro-cyclical patterns in measures of agricultural productivity. Recently constructed national and state-specific indexes of inputs, outputs, and productivity in U.S. agriculture for 1949-2002 are used to estimate production functions in growth rate form that include proxy variables for changes in the utilization of durable inputs. The proxy variables include an index of farmers’ terms of trade and an index of local seasonal growing conditions. We find that utilization responses by farmers are significant and bias measures of productivity growth in a pro-cyclical pattern. We quantify the bias, adjust the measures of productivity for the estimated utilization responses, and compare the adjusted and conventional measures.

description: Superordinate constructions and meaning making structures are hypothesised by different psychological theories to provide individuals with a sense of integration of events or sense-making, which is associated to psychological wellbeing. There has been a general dearth of research in relation to the integration / sense-making of the COVID-19 pandemic events in Higher Education student populations. Personal Construct Psychology’s (Kelly, 1955) methods such as repertory grids and ladders are especially useful tools in the study of sense-making processes. An online survey which included repertory grids, ladders, and questionnaires of meaning and psychological wellbeing was completed by N=101 students from the University of Hertfordshire. The aims were to explore the students’ construing of the COVID-19 pandemic, and to test a series of hypotheses proposed as strategies for clinicians to identify superordinate constructs in repertory grids and ladders, which could help them promote sense-making during interventions. Emotional, relational and personal content predominated the students’ construing of the pandemic; issues related to potentially divisive social or political dynamics of the pandemic generated less important constructs. Although more than half of the sample had levels of psychological distress above clinical thresholds for anxiety, the COVID-specific anxiety was low. Students from the global majority showed lower levels of sense-making of their pandemic worst events than white students. Two grid and ladder measures were associated to positive outcomes in measures of sense-making and psychological wellbeing: overall grid construct intensity and number of ladder rungs. These relationships were stronger when laddering was undertaken from the participants’ least important constructs, which were also more reliably identified by them in comparison with the more important constructs. Clinical implications of these findings and future directions for research are discussed. Limitations were related to data-quality issues arising from the online methodology, as well as from probable statistical underpowering.

description: Исследования проводили с целью изучения продуктивности севооборота с сахарной свеклой и его энергетической оценки при краткосрочном и длительном применении удобрений. Работу выполняли в условиях лесостепи ЦЧР в стационарном полевом опыте на выщелоченном черноземе. Проанализированы данные за 1936-1945 (1-я ротация) и 2009-2017 (9-я ротация) гг. Увеличение длительности применения удобрений способствовало повышению урожайности основной и побочной продукции культур севооборота, продуктивности 1 га пашни, окупаемости 1 кг удобрений и энергетической эффективности их применения, относительно контроля. Продуктивность 1 га севооборотной площади в варианте без удобрений от 1-й к 9-й ротации снижалась на 7,5 % вследствие ухудшения почвенного плодородия, а на фоне действия систем N30P30K30 + 2,8 т/га навоза и N42P42K42 отмеченомаксимальное в опыте её повышение на 12,2 и 7,7 % соответственно. Окупаемость 1 кг NPK прибавкой продукции во времени возрастала на 3,94...7,83 зерн. ед. (64,0...140,0 %). Отмечено увеличение разницы в продуктивности удобренных вариантов, относительно контроля с 11,0...22,6 % в 1-й ротации до 24,2...43,0 % в 9-й ротации. Увеличение длительности использования удобрений обеспечивало повышение коэффициента их энергетической эффективности в 9-й ротации, по сравнению с 1-й, в 1,4...2,2 раза при максимальных в опыте величинах этого показателя (6,16...6,98) в вариантах N10P10K10 + 2,8 т/га навоза, N30P30K30 + 2,8 т/га навоза и N42P42K42. Наибольшую в опыте продуктивность, окупаемость 1 кг NPK и энергетическую эффективность в 1-й ротации обеспечивала система удобрений N27P27K27 + 5,6 т/га навоза, в 9-й - N30P30K30 + 2,8 т/га навоза

description: Western-European consumers have become not only more demanding on product availability in retail outlets but also on other food attributes such as quality, integrity, and safety. When (re)designing food supply-chain networks, from a logistics point of view, one has to consider these demands next to traditional efficiency and responsiveness requirements. The concept ‘quality controlled logistics’ (QCL) hypothesizes that if product quality in each step of the supply chain can be predicted in advance, goods flows can be controlled in a pro-active manner and better chain designs can be established resulting in higher product availability, constant quality, and less product losses. The paper discusses opportunities of using real-time product quality information for improvement of the design and management of ‘AgriFood Supply Chain Networks’, and presents a preliminary diagnostic instrument for assessment of ‘critical quality’ and ‘logistics control’ points in the supply chain network. Results of a tomato-chain case illustrate the added value of the QCL concept for identifying improvement opportunities in the supply chain as to increase both product availability and quality. Future research aims for the further development of the diagnostic instrument and the quantification of costs and benefits of QCL scenarios.

description: With the current federal farm bill set to expire at the end of September this year, many proposals have been made to redesign the next bill. The objectives of this study are to compare the current policy with major proposed alternatives and estimate the potential payments of farmers under each of the alternatives. The alternative policies are compared in two ways. First a historical comparison of crop revenue and estimated government payments for individual farms are made under each proposal from 2002-2005. In a second comparison, projections of crop revenue and government payments are made using historical yields for each farm, county, and nation; historical price data; statistical distributions of the yields and prices including averages, standard deviations, and correlations; and each proposal's rules for calculating payments. For yields, deviations from the yield trend are used. In three of the four years and on average, the American Soybean Association (ASA) proposal has higher payments and thus higher total gross revenue compared to current policy and the other three proposals. Since the ASA proposal raises both loan rates and target prices, the higher payments should be expected. The proposed USDA policy is estimated to have a slightly higher average government payment and total gross revenue compared to current policy, but it is not higher than current policy in each year. Lower total payments under the National Corn Growers Association (NCGA) proposal are due to higher than average revenues during 2002-05. The revenue insurance proposal does not create any indemnity payments in 2002-05 again due to the higher revenues in these years. Projections of potential revenue also show the ASA proposal to have higher estimated payments. Average government payments are estimated to be slightly higher under current policy compared to USDA's and NCGA's proposals. Since federal budget concerns may not allow the higher payments under the ASA proposal, the choice between the USDA and NCGA proposal may hinge on the level of administrative costs which would appear to be lower with the USDA proposal since it is based on one national estimate of revenue versus many county and individual calculations under the NCGA proposal. The potential use of multi-commodity revenue insurance will hinge on either the ability to provide additional support in fixed direct payments and green payments and larger federal budget concerns.

description: Neutrinos give a novel probe to explore deep interior of astrophysical objects, which otherwise is not accessible with optical observations; among notable examples are solar and supernova neutrinos. We show that there is a new class of strong neutrino emission from helium burning, N + alpha --> 18F gamma followed by beta decay 18F --> 18O + e+ + nu_e, that gives a maximum neutrino luminosity of 10^8 times the solar bolometric luminosity at the helium-core flash of a 1 M_sun star, whereas the flash is not observable by optical means. This means that the neutrino flux, of average energy of 0.382 MeV, will be 10% the solar CNO neutrino flux on Earth if the star is located at 10pc.

description: Attosecond pulses can ionize atoms in a coherent process. Since the emerging fragments are entangled, however, each preserves only a fraction of the initial coherence, thus limiting the chance of guiding the ion subsequent evolution. In this work, we use \emph{ab initio} simulations of pump-probe ionization of helium above the $2s/2p$ threshold to demonstrate how this loss of coherence can be controlled. Thanks to the participation of $2\ell n\ell'$ states, coherence between the ionic $2s$ and $2p$ states, which are degenerate in the non-relativistic limit, results in a stationary, delay-dependent electric dipole. From the picosecond real-time beating of the dipole, caused by the fine-structure splitting of the $n=2$ manifold, it is possible to reconstruct all original ion coherences, including between antiparallel-spin states, which are sensitive probe of relativistic effects in attosecond photoemission.

description: Исследования проводили с целью изучения влияния сбалансированных норм удобрений, протравливания семенного материала и сроков посадки на величину и качество урожая клубней картофеля. Работу выполняли в лесостепи Челябинской области в 2015-2017гг. Почва - чернозем выщелоченный среднесуглинистый с содержанием гумуса 5,9...6,3 %. Схема опыта включала 36 вариантов - 3 срока посадки (12... 15 мая, 25.29 мая, 5.12 июня), 2 варианта предпосадочной обработки клубней (без обработки и фунгицидом Максим, 0,4 л/т), 3 уровня минерального питания (без удобрений, удобрения в расчете на урожай клубней 25 и 40 т/га), 2 сорта (Розара и Кузовок). Лучшие условия для формирования планируемой урожайности 40 т/ га создавались при посадке 12. 15 мая протравленным семенным материалом на фоне N172Р242К244. Площадь листьев сорта Розара в этом варианте (40,3 тыс. м2/га) была больше, чем в контроле, в 2,08 раза, Кузовок (48,8 тыс. м2/га) - в 1,99 раза, что обеспечило заданный уровень продуктивности: 38,8 т/га и 43,2 т/га соответственно. Обработка клубней во время посадки фунгицидом Максим (0,4 л/т) снижала развитие возбудителя ризоктониоза, по сравнению с контролем, увеличивало полевую всхожесть (на 1,7...3,8 %), площадь листьев (на 11,3.14,7 %) и, в итоге, урожайность (Кузовок - на 3,3 т/га, Розара - на 4,1 т/га). Оптимальный срок посадки картофеля (12.15 мая) обеспечивал повышение урожайности сорта Розара, по сравнению с посадкой 5.12 июня, на 2,6 т/га, Кузовок - на 5,8 т/га, крахмалистость клубней при этом возрастала соответственно на 1,6 и 2,0 %.

description: The region of northeastern British Columbia includes the transition from cratonic North America to the deformed Canadian Cordillera. While geological mapping has progressed for over 120 years in the northern Cordillera, the subsurface has remained terra incognita as few geophysical surveys have been conducted. The SNoRE '97 seismic refraction/wideangle reflection (R/WAR) survey was carried out to determine the velocity structure of the lithosphere in northwestern Canada. It sampled four separate seismic profiles along the three corridors of the LITHOPROBE SNorCLE transect. This thesis focuses on the results for Line 21. From east to west, the line begins in the Proterozoic Fort Simpson magmatic arc terrane, crosses the accreted Nahanni terrane, transects the Foreland Belt and samples the edge of the Omineca Belt just west of the Tintina Fault. The refraction data set shows good signal-to-noise ratios; primary phases (Pg, PmP and Pn) are clearly observed for most shots. A velocity structural model is achieved first through τ — p analysis, then forward ray trace modeling and 2-d inversion of traveltimes and forward amplitude modeling using RAYINVR, a widely applied, ray-theory-based algorithm developed for R/WAR studies. The resolved velocity structural model demonstrates a westward thickening package of low upper crustal velocities (6.2 km/s and less) extending to almost 20 km depth along the eastern portion of the profile below the WCSB. Beneath the westward thickening low velocities, a west-facing ramp of higher velocities, resolved in the middle and lower crust, is interpreted as the rifted margin of cratonic North America, which was overlain by low velocity, passive margin sediments during the mid-to-late Proterozoic and early Paleozoic. The eastern part of the Foreland Belt shows high velocities (6.4 km/s) in the upper five kilometers, indicating rocks upthrust from deeper in the crust. At the western end of the line, a narrow trench of low velocities at the surface of the model is inferred to represent sediments and brecciated surface rocks filling in the scar of the crustal-scale Tintina Fault. The location of the fault is resolved ~ 20 km to the west of its current inferred location. The depth to Moho is ~ 34 km in the Omineca Belt, deepens to ~ 38 km below the eastern Foreland Belt, and shallows to 34 km at the Cordilleran deformation front. The upper mantle is laterally heterogeneous with anomalously high velocities (up to 8.3 km/s) beneath the Foreland Belt flanked by regions of low velocities (7.7-7.8 km/s). Results from 3-D Bouguer gravity inversion, 2.5-D Bouguer gravity forward modeling and aeromagnetic comparisons performed in this thesis are combined with results from heat flow analyses and previous geophysical studies to check the consistency of the resolved velocity model and to constrain the interpretation of the tectonic evolution of northeastern British Columbia.

description: Metamaterials present the possibility of artificially generating advanced functionalities through engineering of their internal structure. Artificial spin networks, in which a large number of nanoscale magnetic elements are coupled together, are promising metamaterial candidates that enable the control of collective magnetic behavior through tuning of the local interaction between elements. In this work, the motion of magnetic domain-walls in an artificial spin network leads to a tunable stochastic response of the metamaterial, which can be tailored through an external magnetic field and local lattice modifications. This type of tunable stochastic network produces a controllable random response exploiting intrinsic stochasticity within magnetic domain-wall motion at the nanoscale. An iconic demonstration used to illustrate the control of randomness is the Galton board. In this system, multiple balls fall into an array of pegs to generate a bell-shaped curve that can be modified via the array spacing or the tilt of the board. A nanoscale recreation of this experiment using an artificial spin network is employed to demonstrate tunable stochasticity. This type of tunable stochastic network opens new paths towards post-Von Neumann computing architectures such as Bayesian sensing or random neural networks, in which stochasticity is harnessed to efficiently perform complex computational tasks.

description: Исследования проводили с целью оценки возможности длительного выращивания мискантуса и его фитомелиоративного воздействия на почву агроценоза. Посадки мискантуса закладывали в 2005, 2009 и 2015 гг. в Новосибирском Приобье. Почвы - серая лесная и дерново-подзолистая. Надземную биомассу растений отбирали в период их старения, определяли содержание общего азота, фосфора, калия, магния (по Гинзбург); учитывали урожайность и качество сырья. Пробы почвы отбирали послойно (каждые 20 см) в фазе старения растений, определяли содержание гумуса (по Тюрину), нитратного азота (на иономере), легкоподвижного фосфора (по Францесону), обменного калия и магния (в 1 М CH3COONH4). Мискантус может эффективно произрастать на почвах с низким уровнем плодородия. В условиях региона плантации можно бессменно возделывать без снижения урожайности в течение не менее 14 лет. В 2018 г. на делянках 2005 г. посадки она составляла 12,4 т/га, 2009 г. посадки - 14,3 т/га, 2015 г. - 10,8 т/га. Ежегодный вынос с урожаем азота из почвы был равен 17.20 кг/га, фосфора - 11.17, калия - 35.40, магния - 2.3 кг/га, что свидетельствует о невысоких размерах их отчуждения. Содержание целлюлозы в биомассе мискантуса составляло 53 %. За 11 лет бессменного выращивания культуры содержание гумуса в почве возросло на 0,3...0,4 % (как по сравнению с исходной старопахотной почвой, так и почвой пара). Отмечена тенденция накопления подвижных форм зольных элементов в верхнем почвенном слое под мискантусом: содержание легкообменного фосфора составило 12,6 мг/кг, обменного магния - 3,6 мг/100 г (в почве пара 10,6 мг/кг и 3,1 мг/100 г соответственно).

description: The intense process of internationalization of the food market is giving rise to new competitive scenarios. Growing market shares on the part of new export countries, along with other consumer and retail issues, impose different marketing policies for agri-food products. In particular, greater consumer awareness of environmental and health issues is changing the structure of demand for fresh products. In the past, the country of origin and a good quality/price ratio were the main strategic strengths for gaining and maintaining international market shares. Nowadays, market shares are gained by moving towards new product attributes, namely environmental friendliness and food safety. This paper draws attention to new, more successful marketing strategies. The case study is the German cherry tomato market. Our analysis of German consumer preferences on stated choice data produces interesting insights. Product attributes related to the environment are found to be relevant to forming consumer preferences. As these are termed "faith" attributes, we speculate that German consumers refer to product origin country as a proxy of its environmental aspects. Two separate competitive segments emerge, one with a higher level of environmental quality, namely Germany and Italy, and the other comprising Turkey, Spain, France and Holland.

description: Transparency in the Food Sector and especially towards consumers is an issue which receives increasingly attention in public and research. There is widespread agreement that the present state of transparency is not sufficient and needs engagement by research and the sector to move forward. A Strategic Research Agenda on Transparency (SRA) identifies opportunities and challenges for research to contribute to improvements in transparency supporting consumers’ trust in food and the society’s interest in food that is safe and considers the evolving environmental and social concerns.

description: Следуя глобальным трендам, перед российским аграрным сектором поставлена задача цифровой трансформации. Для ее решения необходимо развитие новых интеллектуальных методов и моделей. Модели на базе искусственных нейронных сетей более эффективны, чем традиционные подходы, основанные только на физическом или математическом моделировании, в решении многих проблем. Использование динамической искусственной нейронной сети для прогнозирования среднегодового количества осадков обеспечивает увеличение точности, по сравнению с классическим математическим моделированием, на 25... 30 %. Исследование фактических скоростей движения дождевальных машин показывает их значительное отклонение от требуемых более чем на 10 %, что снижает эффективность орошения. Цель исследований -разработать архитектуру системы управления орошением на базе нейросетевых технологий. В основу системы положены две нейросетевые модели: прогноз агроклиматических ресурсов с использованием динамической искусственной нейронной сети и нейроуправление дождевальной техникой на основе многослойной искусственной нейронной сети. Нейросетевое моделирование проводили с использованием данных системы мониторинга климата Росгидромета и собственной системы сбора технических данных дождевальных машин Саратовского государственного аграрного университета. На основе многослойной нейронной сети синтезировали нейроконтроллер скорости. Его включение в контур управления машиной позволяет снизить отклонения скоростей движения до I.3 %, оптимизируя работу дождевальной техники. Тестирование системы управления осуществляли на основе интеграции в комплексную цифровую платформу для управления агробизнесом «Агросигнал» в научно-производственном объединении Саратовского государственного аграрного университета. Ее использование обеспечило повышение качества орошения и эконо мию около 6 % оросительной воды.

description: Alice is a charismatic quantum cryptographer who believes her parties are unmissable; Bob is a (relatively) glamorous string theorist who believes he is an indispensable guest. To prevent possibly traumatic collisions of self-perception and reality, their social code requires that decisions about invitation or acceptance be made via a cryptographically secure variable bias coin toss (VBCT). This generates a shared random bit by the toss of a coin whose bias is secretly chosen, within a stipulated range, by one of the parties; the other party learns only the random bit. Thus one party can secretly influence the outcome, while both can save face by blaming any negative decisions on bad luck. We describe here some cryptographic VBCT protocols whose security is guaranteed by quantum theory and the impossibility of superluminal signalling, setting our results in the context of a general discussion of secure two-party computation. We also briefly discuss other cryptographic applications of VBCT.

description: Current hydrodynamical and semi-empirical simulations of galaxy formation and evolution have difficulties in reproducing the number densities of IR-detected galaxies. Therefore, a versatile, phenomenological new simulation tool is necessary to reproduce current and predict future observations at IR wavelengths. In this work we generate simulated catalogues starting from the Herschel infrared luminosity functions of different galaxy populations, in order to consider in a consistent way different populations of galaxies and active galactic nuclei. We associated a spectral energy distribution and physical properties, such as stellar mass, star-formation-rate and AGN contribution, to each simulated galaxy using a broad set of empirical relations. We compare the resulting simulated galaxies, extracted up to z$=$10, with a broad set of observational relations. The Spectro-Photometric Realisations of Infrared-selected Targets at all-z (SPRITZ) simulation will allow us to obtain in a fully consistent way simulated observations for a broad set of current and future facilities with photometric capabilities as well as low-resolution IR spectroscopy, like the James Webb Space Telescope (JWST) or the Origin Space Telescope (OST). The derived simulated catalogue contains galaxies and active galactic nuclei that by construction reproduce the observed IR galaxy number density, but it is also in agreement with the observed number counts from UV to far-IR wavelengths, the observed stellar mass function, the star-formation-rate vs. stellar mass plane and the luminosity function from the radio to the X-ray. The proposed simulation is therefore ideal to make predictions for current and future facilities, in particular, but not limited to, those operating at IR wavelengths. The SPRITZ simulation will be publicly available.

description: Using 23 years of data (1978-2000), this study examines seven vertically integrated sugar beet plants representing three different companies in the United States. The objective of this research is to identify the marginal costs of producing sugar beets for vertically integrated sugar beet processors as a way of determining the cost savings from higher quality sugar beets. In doing so, we account for quality differences in the sugar beet input that are used to manufacture the refined sugar output. The results quantify links between high quality sugar beets and lower processing costs.
