description: We study the a, b and c coefficients of the isobaric-multiplet mass equation using a macroscopic-microscopic approach developed by P. Moeller and his collaborators in ADNDT 59, 185 (1995) and ADNDT 109-110, 1 (2016). We show that already the macroscopic part of the finite-range liquid-drop model (FRLDM) describes the general trend of the a and b coefficients relatively well, while the staggering behavior of b coefficients for doublets and quartets can be understood in terms of the difference of average proton and neutron pairing energies. The sets of isobaric masses, predicted by the full macroscopic-microscopic approaches, are used to explore the general trends of IMME coefficients up to A=100. We conclude that while the agreement for a coefficients is quite satisfactory, the global approaches have less sensitivity to predict the staggering pattern observed for b coefficients of doublets and quartets. The best set of theoretical b coefficients for multiplets up to about A=100 is used to predict masses of proton-rich nuclei based on the known experimental masses of neutron-rich mirror partners, and subsequently to investigate their one- and two-proton separation energies. The estimated position of the proton-drip line is in fair agreement with known experimental data. These masses are important for simulations of the astrophysical rp-process.

Survey of Mortgage Lenders, 2000
Survey of Mortgage Lenders, 1992-
Creators: name: Department Of The Environment, Transport
Publisher: name: UK Data Service
Year: 2001

description: The Survey of Mortgage Lenders (SML) was launched on 1st April 1992 to succeed the 5% Sample Survey of Building Society Mortgage Completions (BSM) (See GN:33191). The aims were to improve the survey in three principal ways:

a) to broaden the range of institutions surveyed to incorporate other mortgage lenders in addition to building societies and Abbey National. With the entry of the high street banks and then the centralised lenders into the mortgage market, information provided by the building societies no longer represented the whole market in the way it did when the BSM was set up in the 1960s.

b) to extend its coverage to include further advances, remortgages and top-up loans in addition to first mortgages.

c) to increase the level of detail on the questionnaire especially with respect to the characteristics of the mortgage loan.

An important consideration for users of the data is that the SML figures allow continuity with the BSM survey results to be maintained for a reasonable period.
Core-collapse, superluminous, and gamma-ray burst supernova host galaxy populations at low redshift: the importance of dwarf and starbursting galaxies

description: We present a comprehensive study of an unbiased sample of 150 nearby ( = 0.014) core-collapse supernova (CCSN) host galaxies drawn from the All-Sky Automated Survey for Supernovae (ASAS-SN) for direct comparison to the nearest LGRB and SLSN hosts. We use public imaging surveys to gather multi-wavelength photometry for all CCSN host galaxies and fit their spectral energy distributions (SEDs) to derive stellar masses and integrated star formation rates. CCSNe populate galaxies across a wide range of stellar masses, from blue and compact dwarf galaxies to large spiral galaxies. We find 33(+4,-4) per cent of CCSNe are in dwarf galaxies (M < 10^9 M_Sun) and 2(+2,-1) per cent are in dwarf starburst galaxies (sSFR > 10^-8 yr^-1). We reanalyse low-redshift SLSN and LGRB hosts from the literature (out to $z<0.3$) in a homogeneous way and compare against the CCSN host sample. The relative SLSN to CCSN supernova rate is increased in low-mass galaxies and at high specific star-formation rates. These parameters are strongly covariant and we cannot break the degeneracy between them with our current sample, although there is some evidence that both factors may play a role. Larger unbiased samples of CCSNe from projects such as ZTF and LSST will be needed to determine whether host-galaxy mass (a proxy for metallicity) or specific star-formation rate (a proxy for star-formation intensity and potential IMF variation) is more fundamental in driving the preference for SLSNe and LGRBs in unusual galaxy environments.

description: Scalar and tensor perturbations arising in an inflationary braneworld scenario driven by a single scalar field are considered, where the bulk on either side of the brane corresponds to Anti-de Sitter spaces with different cosmological constants. A consistency relation between the two spectra is derived and found to have an identical form to that arising in standard single-field inflation based on conventional Einstein gravity. The dS/CFT correspondence may provide further insight into the origin of this degeneracy. Possible ways of lifting such a degeneracy are discussed.

description: The first opportunity to detect indications for life outside the Solar System may be provided already within the next decade with upcoming missions such as the James Webb Space Telescope (JWST), the European Extremely Large Telescope (E-ELT) and/or the Atmospheric Remote-sensing Infrared Exoplanet Large-survey (ARIEL) mission, searching for atmospheric biosignatures on planets in the habitable zone of cool K- and M-stars. Nevertheless, their harsh stellar radiation and particle environment could lead to photochemical loss of atmospheric biosignatures. We aim to study the influence of cosmic rays on exoplanetary atmospheric biosignatures and the radiation environment considering feedbacks between energetic particle precipitation, climate, atmospheric ionization, neutral and ion chemistry, and secondary particle generation. We describe newly-combined state-of-the-art modeling tools to study the impact of the radiation and particle environment on atmospheric particle interaction, the influence on the atmospheric chemistry, and the climate-chemistry coupling in a self-consistent model suite. To this end, models like the Atmospheric Radiation Interaction Simulator (AtRIS), the Exoplanetary Terrestrial Ion Chemistry model (ExoTIC), and the updated coupled climate-chemistry model are combined. Amongst others, we model the atmospheric response during quiescent solar periods and during a strong solar energetic particle event as well as the scenario-dependent terrestrial transit spectra, as seen by the NIR-Spec infrared spectrometer onboard the JWST. We find that the comparatively weak solar event drastically increases the spectral signal of HNO$_3$, while significantly suppressing the spectral feature of ozone. Because of the slow recovery after such events, the latter indicates that ozone might not be a good biomarker for planets orbiting stars with high flaring rates.

Scottish School-leavers Survey, 1994 : 1993 Leavers
Scottish School-Leavers Survey, 1992-
SSLS
Creators: name: Social And Community Planning Research
Publisher: name: UK Data Service
Year: 2001

description: The Scottish Executive has sponsored surveys of school-leavers and young people since the early 1970s. These include the first incarnation of the Scottish School-Leavers Survey (SSLS) which, in the mid-1980s, was subsumed within the broader Scottish Young People's Survey (SYPS - this series is held at the UK Data Archive (UKDA) under GN 33227). Following a review in 1991 of the use made of the findings by the Scottish Executive Education and Industry Department (SEEID), the survey was redesigned and resumed the title of the Scottish School-Leavers Survey. A further review in 1996 led to the establishment of the current design, which involves sampling cohorts of young people in fourth year and then collecting data from them on four occasions, at the ages of 16-17, 18-19, 21-22 and 23-24 years.

The series is conducted for the Scottish Executive by the National Centre for Social Research (NatCen), who were known as Social and Community Planning Research prior to 1999. The Scottish Centre for Social Research (SCSR or ScotCen) was created in 2004 by combining NatCen's existing operation in Scotland with an independent research consultancy, Scottish Health Feedback. SCSR have now taken over the running of the SSLS series.

The SSLS series obtains information on the educational and employment activities of young people after they leave school; their views and experiences of school itself; and key decisions made about whether to stay on at school or not. In addition, background characteristics are gathered, such as parents' level of education and social class, family circumstances and housing tenure. One of the main aims of the survey is to try and predict demand for higher education. The survey involves a random sample of all pupils in the relevant school year group. The only exception is that pupils at special schools (but not those in mainstream schools registered as having special educational needs) are excluded from the survey. The sample consists of all pupils born on any one of certain predetermined days of the month.

description: Beliefs are important determinants of an individual's choices and economic outcomes, so understanding how they comove and differ across individuals is of considerable interest. Researchers often rely on surveys that report individual beliefs as qualitative data. We propose using a Bayesian hierarchical latent class model to analyze the comovements and observed heterogeneity in categorical survey responses. We show that the statistical model corresponds to an economic structural model of information acquisition, which guides interpretation and estimation of the model parameters. An algorithm based on stochastic optimization is proposed to estimate a model for repeated surveys when responses follow a dynamic structure and conjugate priors are not appropriate. Guidance on selecting the number of belief types is also provided. Two examples are considered. The first shows that there is information in the Michigan survey responses beyond the consumer sentiment index that is officially published. The second shows that belief types constructed from survey responses can be used in a subsequent analysis to estimate heterogeneous returns to education.

description: In this work, the field of a gravitational shockwave generated by a massless point-like particle is calculated at the event horizon of a stationary Kerr-Newman black hole. Using the geometric framework of generalized Kerr-Schild deformations in combination with the spin-coefficient formalism of Newman and Penrose, it is shown that the field equations of the theory, at the event horizon of the black hole, can be reduced to a single linear ordinary differential equation for the so-called profile function of the geometry. This differential relation is solved exactly. Based on the results obtained, a physical interpretation is given for the found shockwave spacetime, and it is clarified how these results lead back to those of previous works on the subject, which deal with the much simpler cases of gravitational shockwaves in static black hole backgrounds.

description: We study spectral and transport properties of interacting quantum dots with spin. Two particular model systems are investigated: Lateral multilevel and two parallel quantum dots. In both cases different paths through the system can give rise to interference. We demonstrate that this strengthens the multilevel Kondo effect for which a simple two-stage mechanism is proposed. In parallel dots we show under which conditions the peak of an interference-induced orbital Kondo effect can be split.

description: We construct a model for noncommutative gravity in four dimensions, which reduces to the Einstein-Hilbert action in the commutative limit. Our proposal is based on a gauge formulation of gravity with constraints. While the action is metric independent, the constraints insure that it is not topological. We find that the choice of the gauge group and of the constraints are crucial to recover a correct deformation of standard gravity. Using the Seiberg-Witten map the whole theory is described in terms of the vierbeins and of the Lorentz transformations of its commutative counterpart. We solve explicitly the constraints and exhibit the first order noncommutative corrections to the Einstein-Hilbert action.

From this we deduce the anomalous slow behavior for a Brownian Motion in a potential obtained as a superposition of an infinite number of scales: $dy_t=dω_t -\nabla V^\infty(y_t) dt$

description: Diese Arbeit beschäftigt sich mit der Elektronen Transportschicht (ETL) in einer Perowskit-Solarzelle. Dabei wurde der Fokus auf das Material Zinn(IV)-oxid (SnO2) gelegt, um einen Ersatz zu Titan(IV)-oxid (TiO2) in einer Perowskit-Solarzelle als ETL zu finden. Aus den erstellten Zellen hat sich gezeigt, dass die Titan(IV)-oxid (TiO2) Schicht die höchste Effizienz hat. Diese wurden mit dem Wert von 13,8% als effizienteste Zelle erstellt und gemessen. Dennoch ist der hohe Produktionsaufwand mit zwei Schichtauftragungen, die jeweils bei 400°C erhitzt werden müssen, recht hoch. Auch der Transmissi-onswert der TiO2 Schichten ist geringer als bei der Zinn(IV)-Oxid (SnO2) Schicht. Die Herstellung der SnO2 und der Produktionsaufwand der SnO2 Lösung sind mit 180°C geringer als bei TiO2. Da aber die reine Schicht SnO2 nur eine Effizienz von 11,3% hat, wurde versucht über Dotierung diese Werte zu verbessern. Es wurden Versuche mit EDTA und Graphen (rGO) als Dotierzusatz durchgeführt. Dabei ist der Effizienzwert auf 12,2% gestiegen und damit schon fast auf dem TiO2 Niveau. Alle Solarzellen wurden auf weitere wichtige Vergleichswerte analysiert. Das Ergebnis der Forschung war, dass die SnO2 Schicht von den Solarzellen Parameter noch nicht an die Zellen mit eine TiO2 Schicht als ETL heran-kommt aber dass sie sich schon sehr gut an diese annähert und weitere Forschungen sich lohnen.

description: Within the scope of a Key Programme determining fundamental parameters of stars observed by HIPPARCOS, spectra of 525 B8 to F2-type stars brighter than V=8 have been collected at ESO. Fourier transforms of several line profiles in the range 4200-4500 A are used to derive vsini from the frequency of the first zero. Statistical analysis of the sample indicates that measurement error is a function of vsini and this relative error of the rotational velocity is found to be about 6% on average. The results obtained are compared with data from the literature. There is a systematic shift from standard values from Slettebak et al. (1975), which are 10 to 12% lower than our findings. Comparisons with other independent vsini values tend to prove that those from Slettebak et al. are underestimated. This effect is attributed to the presence of binaries in the standard sample of Slettebak et al., and to the model atmosphere they used.

description: Short-Term Load Forecasting (STLF) is a critical and complex task that plays a vital role in the efficient management of electricity generation, transmission, and distribution. Recent research has made strides in this field through the application of advanced deep learning techniques to enhance the accuracy and reliability of load predictions. The first study introduces a novel deep neural network tailored for STLF at Memorial University of Newfoundland (MUN). This model integrates electric load data with meteorological information and features a 1D Convolutional Neural Network followed by an Encoder-Decoder Network with an attention mechanism, showing superior performance compared to traditional Gated Recurrent Unit (GRU) and Long Short Term Memory (LSTM) models. The study also focuses on optimizing the input horizon using the algorithm. The second study focuses on Multi-Energy Systems (MES) and presents a Multi-Task Learning-based approach for load forecasting. It features a cutting-edge deep learning architecture designed to forecast multiple loads simultaneously. Applied to the University of Austin Tempe Campus, this approach employs a Deep Temporal Convolutional Neural Network (D-TCNet) to effectively capture spatial and temporal correlations in the data, resulting in improved forecasting accuracy across different energy types and seasons. The third study compares various Recurrent Neural Network (RNN)-based time-series forecasting algorithms, including LSTM, GRU, Bi-directional GRU, and Bi-directional LSTM, on electric load data from MUN. The Bi-directional GRU model emerged as the top performer, achieving the highest R2 score and the lowest Mean Squared Error (MSE) and Mean Absolute Error (MAE) for day-ahead predictions. Collectively, these studies demonstrate the power of deep learning in enhancing the precision and effectiveness of short-term load forecasting, offering promising avenues for optimizing energy system operations.

description: Companies try to maximize their profits by recovering returned products of highly uncertain quality and quantity. In this paper, a reverse logistics network for an Original Equipment Manufacturer (OEM) is presented. Returned products are selected for remanufacturing or scrapping, based on their quality and proportional prices are offered to customers. A Mixed Integer Non-linear Programming (MINLP) model is proposed to determine the location of collection centers, the optimum price of returned products and the sorting policy. The risk in the objective function is measured using the Conditional Value at Risk (CVaR) metric. CVaR measures the risk of an investment in a conservative way by considering the maximum lost. The results are analyzed for various values of the risk parameters (α, and λ). These parameters indicate that considering risk affects prices, the classification of returned products, the location of collection centers and, consequently, the objective function. The model performs more conservatively when the weight of the CVaR part (λ) and the value of the confidence level α are increased. The results show that better profits are obtained when we take CVaR into account.

description: Differential privacy allows quantifying privacy loss resulting from accessing sensitive personal data. Repeated accesses to underlying data incur increasing loss. Releasing data as privacy-preserving synthetic data would avoid this limitation, but would leave open the problem of designing what kind of synthetic data. We propose formulating the problem of private data release through probabilistic modelling. This approach transforms the problem of designing the synthetic data into choosing a model for the data, allowing also including prior knowledge, which improves the quality of the synthetic data. We demonstrate empirically, in an epidemiological study, that statistical discoveries can be reliably reproduced from the synthetic data. We expect the method to have broad use in creating high-quality anonymized data twins of key data sets for research.

description: There are many observational evidences for the existence of massive compact condensations in the range $10^6 -10^{10} M_\odot$ at the core of various galaxies. At present such condensations are commonly interpreted as Black Holes (BHs). However, we point out that while such Black Hole Candidates (BHCs) must be similar to BHs in many respects they, actually, can not be BHs because existence of Black Holes would violate the basic tenet of the General Theory of Relativity (GTR) that the worldline of a material particle must be timelike at any regular region of spacetime. On the other hand general relativistic collapse of very massive bodies should lead to Eternally Collapsing Configurations (ECOs) or Ultra Compact Objects (UCOs). While ECOs/UCOs may practically be as compact as corresponding BHs, they will have a physical surface. Also while BHs do not have any intrinsic magnetic field ECOs may have strong intrinsic magnetic field. We point out that despite many claims actually there is no real evidence for the ``Event Horizon'' (EH) of supposed BHs and on the other hand, there are tentative evidence for the existence of strong magnetic field in several BHCs (or ECOs). The presence of such intrinsic magnetic field may render the task of explaining high energy radiation phenomenon in many Active Galactic Nuclei easier.

description: Spatially uniform optical excitations can induce Floquet topological band structures within insulators which can develop similar or equal characteristics as are known from three-dimensional topological insulators. We derive in this article theoretically the development of Floquet topological quantum states for electromagnetically driven semiconductor bulk matter and we present results for the lifetime of these states and their occupation in the non-equilibrium. The direct physical impact of the mathematical precision of the Floquet-Keldysh theory is evident when we solve the driven system of a generalized Hubbard model with our framework of dynamical mean field theory (DMFT) in the non-equilibrium for a case of ZnO. The physical consequences of the topological non-equilibrium effects in our results for correlated systems are explained with their impact on optoelectronic applications.

Adventure tourism term is a type of tourism able to fulfill these types of human needs. The aim of the study was to know the Polish tourists opinion about the adventure tourism in Poland. The study involved 50 people, taking into account their gender, age, education and occupational status. The research tool was a survey questionnaire. The study indicated that it is not a popular form of tourism in Poland. Its proponents, the information about places and facilities derive mainly from the Internet. The most popular forms are trekking, tramping, caves exploration, paintball, windsurfing, bungejumping and rafting. Rather average possibility of practicing the adventure tourism in Poland is associated with multitude barriers, mainly financial investments, lack of free time, as well as fear and general fear of some of its forms.

description: Tunneling from a two-dimensional contact into quantum-Hall edges is considered theoretically for a case where the barrier is extended, uniform, and parallel to the edge. In contrast to previously realized tunneling geometries, details of the microscopic edge structure are exhibited directly in the voltage and magnetic-field dependence of the differential tunneling conductance. In particular, it is possible to measure the dispersion of the edge-magnetoplasmon mode, and the existence of additional, sometimes counterpropagating, edge-excitation branches could be detected.

description: Die vorliegende Masterarbeit befasst sich mit einem häufig in der sexualtherapeutischen Praxis auftretendem Thema: Männer, die Unterstützung suchen, weil sie ihren Pornografiekonsum als zu hoch einschätzen. Ziel dieser Arbeit ist es, bestehende theoretische Erklärungsmodelle zur Interpretation des Pornografiekonsums, die hauptsächlich aus dem US-amerikanischen Raum stammen, zusammenzufassen und deren Anwendbarkeit im europäischen, deutschsprachigen gesellschaftlichen Kontext zu prüfen. Im Fokus steht dabei das Modell der pornography problems due to moral incongruence (PPMI-Modell), das die Diskrepanz zwischen den persönlichen moralischen Überzeugungen eines Individuums und seinem tatsächlichen Konsumverhalten als moralische Inkongruenz definiert und als Kernkonzept nutzt. Die Arbeit untersucht, wie Sexualtherapeutinnen und Sexualtherapeuten das PPMI-Modell und die Rolle der moralischen Inkongruenz in ihrer Praxis einschätzen. Dabei wird insbesondere beleuchtet, inwiefern kulturell und gesellschaftlich geprägte Wert- und Moralvorstellungen Einfluss auf die moralische Inkongruenz haben können und ob diese Diskrepanz möglicherweise dazu führen kann, dass sich Personen als 'pornografiesüchtig' betrachten. Zur Untersuchung dieser Aspekte werden Interviews mit führenden Expertinnen und Experten aus der deutschsprachigen Schweiz im Bereich der Sexualtherapie durchgeführt.

description: This paper aims to assess the impact of the use of credit in rice farming on productivity and income in Benin. It applies the potential outcomes framework to data collected from 342 rice farmers in Benin to estiamte the Local Average Treatment Effect (LATE). Findings show that the use of credit in rice farming has positive and significant impact on farmers' rice yield, rice output, rice income, per capita rice income, annual household income and per capita annual household income. Therefore, facilitating access of rice farmers to agricultural credit is a good strategy for supporting rice sector development, and therefore contributing to food security and poverty alleviation in Benin. Moreover, the impacts were higher for female farmers than male farmers. Therefore, it is important to control for heterogeneity in impact assessment studies in order to appreciate the real effect of interventions on different social categories in the target population.

description: In Canada, all fluid milk and cream products must be sourced from Canadian producers under the supply management policy governing the Canadian dairy sector, while other processed dairy products, such as cheese, yogurt, and ice cream can be made using imported milk components. Recently, the Dairy Farmers of Canada launched a 100% Canadian Milk label for products that contain only milk and milk ingredients produced in Canada. This paper uses a Discrete Choice Experiment from a Canada-wide survey of dairy consumers to elicit their willingness-to-pay for ice cream carrying the 100% Canadian Milk label. The results show that Canadian consumers are willing to pay more for ice cream products that carry the label. Consumer knowledge of the dairy sector affects their willingness to pay for this labelling information. Implications for the use of the Canadian origin label and suggestions for further research are discussed.

description: Action Detection is a complex task that aims to detect and classify human actions in video clips. Typically, it has been addressed by processing fine-grained features extracted from a video classification backbone. Recently, thanks to the robustness of object and people detectors, a deeper focus has been added on relationship modelling. Following this line, we propose a graph-based framework to learn high-level interactions between people and objects, in both space and time. In our formulation, spatio-temporal relationships are learned through self-attention on a multi-layer graph structure which can connect entities from consecutive clips, thus considering long-range spatial and temporal dependencies. The proposed module is backbone independent by design and does not require end-to-end training. Extensive experiments are conducted on the AVA dataset, where our model demonstrates state-of-the-art results and consistent improvements over baselines built with different backbones. Code is publicly available at https://github.com/aimagelab/STAGE_action_detection.

Another bar in the Bulge

description: A map of the projected density of the old stellar population of the Galactic Bulge region is reconstructed using 2MASS data. By making a combination of the H and K photometric bands, it is possible to overcome the effect of reddening, and thus penetrate the inner structure of the Galactic Bulge. The main structure in the map corresponds to the well documented peanut shaped bar which is formed by the inner parts of the Galactic disk as a result of dynamical instabilities. As suggested by numerical simulations, the projected Z profile of the bar, has an almost exponential shape. After subtracting the exponential profile associated with the bar, a large residual appear near the Galactic Center. This residual is elongated and asymmetrical, which suggest a bar structure. Thus we arrive at the conclusion that in addition to the main bar a smaller bar with a different orientation may exist in the central region of the Milky Way. This finding makes the Milky Way very similar to a large number of barred spiral Galaxies which show as well a smaller bar in their central regions.

description: «Magnificent Sex» – Herausragende sexuelle Erlebnisse und dazu beisteuernde Faktoren bei Menschen, die über Erfahrungen mit dem Modell Sexocorporel verfügen In der vorliegenden Masterarbeit wird untersucht, wie Menschen, die über Erfahrungen mit dem Modell Sexocorporel verfügen, herausragende Momente in ihrer Sexualität und die dazu beisteuernden Faktoren beschreiben. Ausgehend von den qualitativen Befragungen der Forschungsgruppe rund um Peggy Kleinplatz zu «Magnificent Sex», entstand die Annahme, dass Menschen, die körperorientierte Übungen im Zusammenhang mit dem Modell Sexocorporel gemacht haben, bei ihren Beschreibungen den Fokus auf den Einsatz ihres Körpers richten. Der Literaturteil der Arbeit widmet sich den herausragenden sexuellen Erlebnissen und den beisteuernden körperlichen Faktoren, wie sie im Modell Sexocorporel erwähnt werden, also den drei Dimensionen der Bewegung (Tonus, Rhythmus, Raum: innerer Raum der Atmung und äusserer Raum). In vier qualitativen Interviews wird die Hauptfragestellung erforscht und die damit verbundene Annahme überprüft.

description: This study examines the relationship between budgetary controls and organizational performance, focusing on how effective budgeting strategies drive corporate growth. By analyzing financial reports and industry data from 2020 to 2024, the research employs statistical methods—including correlation, regression, and variance analysis—to assess the impact of budget adherence, budget investment per employee, and strategic budgeting models on profitability, productivity, and revenue growth. The results indicate a strong positive correlation (r = 0.98) between budget adherence and profit margins, with companies increasing profit margins from 8% in 2020 to 12% in 2024. Regression analysis confirms that a $200 increase in budget investment per employee leads to a 5-point productivity index rise (R² = 0.95). Furthermore, variance analysis (ANOVA) reveals that flexible budgeting strategies result in the highest revenue growth (15%), outperforming fixed budgeting models (9%). The findings emphasize the importance of adaptive and technology-driven budgetary controls in achieving financial sustainability. Based on these insights, organizations should implement rolling forecasts, AI-driven budgeting tools, and strategic cost allocation to enhance financial performance and long-term growth.

description: Глобальні інтегративні процеси, що відбуваються у сучасному світовому соціокультурному просторі, зумовлюють прагматизацію суспільства, яка призводить до зниження рівня духовності особистості. Сучасна криза суспільства має прояв у всіх сферах людської діяльності: економічній, політичній, ідеологічній, моральній та духовній. Для свого становлення країна потребує високодуховних творчих особистостей, оскільки чим більш духовно розвиненіша особистість, тим більш актуалізується її творчий потенціал і тим вагоміші її внески у функціонування суспільства. Система освіти пов’язана з процесами, що відбуваються у суспільстві. У зв’язку з цим значно підвищуються вимоги до освіти, зокрема, до дошкільної, і педагога як носія духовності, який формує у підростаючого покоління готовність до самостійного, активного й творчого життя, реалізації свого призначення.

Food Security and Poverty

description: The last decade has seen a resurgence of parastatal crop marketing institutions in sub-Saharan Africa, many of which cite improving food security and incomes as key goals. However, there is limited empirical evidence on the welfare effects of these programs. This study considers one such program, the Zambian Food Reserve Agency (FRA), which purchases maize from smallholder farmers at a pan-territorial price that typically exceeds maize market prices in surplus production areas. Using both fixed effects and an instrumental variables approach combined with correlated random effects, we estimate the effects of the FRA’s maize marketing activities on smallholder farm household welfare. Results suggest that FRA activities have positive direct welfare effects on the small minority of smallholder households that are able to sell to it. However, the results also suggest negative indirect FRA effects, as higher levels of FRA activity in a district are associated with higher levels of poverty.
