Fiscal transparency and policy rules in Poland

This paper assesses the current stance and desirable progress in the implementation of fiscal transparency and rules in Poland. An index of transparency based on Report on the Observance of Standards and Codes (ROSC), with some modifications, is also constructed in this paper, followed by proposals for making transparency and fiscal rules more efficient within Poland's fiscal policy. This study attempts to answer the following questions: Firstly, to what extent is fiscal policy transparent in the context of the standards set by the EU's regulations and the IMF's ROSC? Secondly, have the fiscal rules adopted by Poland proved to be successful in establishing fiscal policy discipline? Finally, what still needs to be changed to make both transparency and fiscal rules more efficient for the conduct of fiscal policy? To set the work in context we also provide an overview of recent advances in both the theoretical and empirical literature on fiscal transparency and rules

An integrated program using TAKTIC to control mange in swine

An integrated treatment program for sarcoptic mange control using TAKTIC@ (omitral.) 12.5% EC was evaluated at eight., privately owned, farrow to finish swine facilities in a four-state area. At all locations the treatment program consisted of an initial whole-herd treatment. phase followed by scheduled treatments applied in conjunction with routine ffionagement practices. Evaluations of mite scrapings taken at scheduled pretreatment and posttreatment intervals showed a 50· 100% reduction in sacroptic mange infestation levels following implementation of the TAKTIC@ treatment program which consisted of an initial treatment and a maintenllnce schedule. Comparison of pretreatment and posttreatment production records showed 10· 15 d earlier maturity in finishing pig market weight, increases of 0.1 -2.1 weaned pigs/Jitter, and decreases in piglet processing and nursing mortality following implementation of the TAKTIC@ treatment program. A theoretical example of the potential for increase return to profit based on these findings is presented

Nectar formation and floral nectary anatomy of Anigozanthos flavidus: a combined magnetic resonance imaging and spectroscopy study

Metabolic processes underlying the formation of floral nectar carbohydrates, especially the generation of the proportions of fructose, glucose, and sucrose, are important for understanding ecological plant–pollinator interactions. The ratio of sucrose-derived hexoses, fructose and glucose, in the floral nectar of Anigozanthos flavidus (Haemodoraceae) was observed to be different from 1:1, which cannot be explained by the simple action of invertases. Various NMR techniques were used to investigate how such an unbalanced ratio of the two nectar hexoses can be formed. High-resolution 13C NMR spectroscopy in solution was used to determine the proportion of carbohydrates in vascular bundles of excised inflorescences fed with 13C-labelled carbohydrates. These experiments verified that feeding did not affect the metabolic processes involved in nectar formation. In vivo magnetic resonance imaging (e.g. cyclic J cross-polarization) was used to detect carbohydrates in vascular bundles and 1H spin echo imaging non-invasively displayed the architecture of tepal nectaries and showed how they are connected to the vascular bundles. A model of the carbohydrate metabolism involved in forming A. flavidus floral nectar was established. Sucrose from the vascular bundles is not directly secreted into the lumen of the nectary but, either before or after invertase-catalysed hydrolyses, taken up by nectary cells and cycled at least partly through glycolysis, gluconeogenesis, and the pentose phosphate pathway. Secretion of the two hexoses in the cytosolic proportion could elegantly explain the observed fructose:glucose ratio of the nectar

Advanced atomic force microscopy techniques

Cataloged from PDF version of article.Although its conceptual approach is as simple as the technique used in record players already introduced in the 19th century, the invention of the atomic force microscope (AFM) in 1986 by Binnig, Quate, and Gerber was a milestone for nanotechnology. The scanning tunneling microscope (STM), introduced some years earlier, had already achieved atomic resolution, but is limited to conductive surfaces. Since its operational principle is based on the detection of the forces acting between tip and sample, this restriction does not exist for the AFM. Consequently, atomic force microscopy quickly became the standard tool for nanometer-scale imaging of all types of surfaces in all environments. True atomic resolution was first achieved in the 1990s. The most convincing results, however, were restricted to the so-called noncontact mode in vacuum for a long time, but recent technical developments overcame this limitation, and atomic-resolution imaging is now also a standard in liquids. Beyond pushing the resolution limit to the picometer range, the invention of the AFM triggered the development of a growing number of new scanning probe methods and approaches, ranging from an expansion of the properties that can be mapped to the active manipulation of surfaces and small particles. Practically every month, reports on the growing capabilities of AFMs appear. Nearly every physical effect that influences the tip–sample interaction has been used to improve existing modes and to develop new ones. For example, many recently presented techniques include the excitation of higher cantilever oscillation modes; it is amazing in how many ways the shaking of a simple cantilever can improve our knowledge about the tip–sample interaction. Another direction is high-speed atomic force microscopy, which is one of the eminent challenges that need to be solved in order to allow the in situ observation of biological processes. Data acquisition times have already reached the millisecond range, enabling the visualization of the dynamic behavior of biological molecules and cells. Other recent accomplishments include imaging of organic molecules with unprecedented resolution, full three-dimensional mapping of surface force fields, and the imaging and discrimination of individual chemical bonds. The development of advanced techniques is the focus of this Thematic Series, following the Thematic Series “Scanning probe microscopy and related techniques” edited by Ernst Meyer and the Thematic Series “Noncontact atomic force microscopy” edited by Udo Schwarz. The articles that are part of the series demonstrate that, despite its 25 years of history, the AFM is still far from reaching its limits, and today’s developments are far-reaching. As the number of research groups utilizing advanced atomic force microscopy techniques increases with each passing year, the technical improvements, data-acquisition approaches, analysis procedures, user friendliness, and application areas of the technique further diversify. With this Thematic Series, it is our intention to stimulate these improvements. We thank all authors for contributing their excellent work to this series. Furthermore, we acknowledge all referees for their promptly provided reports keeping the publication times short and attractive for contributors. Finally, we are grateful to the open access policy of the Beilstein Journal of Nanotechnology providing the ground for unrestricted discussions on advanced atomic force microscopy techniques.

Evaluation of nutrient intakes of pregnant and non-pregnant women

During pregnancy, women need to increase their energy intake and certain vitamins and minerals to ensure that both the mother and fetus remain healthy. Therefore, it is crucial that women-- both pregnant and those capable of becoming pregnant-- are properly nourished to provide a healthy environment for their child. The objective of this study was to determine if pregnant women’s dietary intakes meet their dietary reference intakes (DRIs) independent of supplementation and to determine if non-pregnant women of childbearing age have adequate intakes of key nutrients important for conception and pregnancy. Our study examined 15 pregnant and 15 non-pregnant women between the ages of 20 and 33 years recruited from the Urbana-Champaign area. Study participants completed the National Health and Nutrition Examination Survey (NHANES) Food Frequency Questionnaire (FFQ). FFQ data was then analyzed using Diet*Calc (2013, NCI) and Statistical Analysis System (SAS). Nutrient data was compared to the 2001 Dietary Reference Intake values. There were no differences in mean nutrient intakes between pregnant and non-pregnant women. Both pregnant and non-pregnant women exceeded the DRIs for vitamins A, B12, and C, riboflavin, and n-3 polyunsaturated fatty acids (PUFAs). Our findings indicate that both pregnant and non-pregnant women from the Champaign-Urbana area may benefit from dietary education and/or supplementation in order to prevent development of adverse health effects in the fetus.Ope

No link between handedness and spatial navigation: evidence from over 400 000 participants in 41 countries

There is an active debate concerning the association of handedness and spatial ability. Past studies used small sample sizes. Determining the effect of handedness on spatial ability requires a large, cross-cultural sample of participants and a navigation task with real-world validity. Here, we overcome these challenges via the mobile app Sea Hero Quest. We analysed the navigation performance from 422 772 participants from 41 countries and found no reliable evidence for any difference in spatial ability between leftand right-handers across all countries. A small but growing gap in performance appears for participants over 64 years old, with left-handers outperforming right-handers. Further analysis, however, suggests that this gap is most likely due to selection bias. Overall, our study clarifies the factors associated with spatial ability and shows that left-handedness is not associated with either a benefit or a deficit in spatial ability

Entropy and a Sub-Group of Geometric Measures of Paths Predict the Navigability of an Environment

Despite extensive research on navigation, it remains unclear which features of an environment predict how difficult it will be to navigate. We analysed 478,170 trajectories from 10,626 participants who navigated 45 virtual environments in the research app-based game Sea Hero Quest. Virtual environments were designed to vary in a range of properties such as their layout, number of goals, visibility (varying fog) and map condition. We calculated 58 spatial measures grouped into four families: task-specific metrics, space syntax configurational metrics, space syntax geometric metrics, and general geometric metrics. We used Lasso, a variable selection method, to select the most predictive measures of navigation difficulty. Geometric features such as entropy, area of navigable space, number of rings and closeness centrality of path networks were among the most significant factors determining the navigational difficulty. By contrast a range of other measures did not predict difficulty, including measures of intelligibility. Unsurprisingly, other task-specific features (e.g. number of destinations) and fog also predicted navigation difficulty. These findings have implications for the study of spatial behaviour in ecological settings, as well as predicting human movements in different settings, such as complex buildings and transport networks and may aid the design of more navigable environments

Retinal Morphometric Markers of Crystallized and Fluid Intelligence Among Adults With Overweight and Obesity

Objective: To investigate the relationship between retinal morphometric measures and intellectual abilities among adults with overweight and obesity.Methods: Adults between 25 and 45 years (N = 55, 38 females) with overweight or obesity (BMI ≥ 25.0 kg/m2) underwent an optical coherence tomography (OCT) scan to assess retinal nerve fiber layer (RNFL) volume, ganglion cell layer (GCL) volume, macular volume, and central foveal thickness. Dual-Energy X-ray absorptiometry was used to assess whole-body adiposity (% Fat). The Kaufman Brief Intelligence Test-2 was used to assess general intelligence (IQ), fluid, and crystallized intelligence. Hierarchical linear regression analyses were performed to examine relationships between adiposity and intelligence measures following adjustment of relevant demographic characteristics and degree of adiposity (i.e., % Fat).Results: Although initial bivariate correlations indicated that % Fat was inversely related to fluid intelligence, this relationship was mitigated by inclusion of other demographic factors, including age, sex, and education level. Regression analyses for primary outcomes revealed that RNFL was positively related to IQ and fluid intelligence. However, only GCL was positively related to crystallized intelligence.Conclusion: This work provides novel data linking specific retinal morphometric measures – assessed using OCT – to intellectual abilities among adults with overweight and obesity.Clinical Trial Registration:www.clinicaltrials.gov, identifier NCT02740439
