Insignificant Correlation

Three-year research, in the impact of microbial preparations and Gunatito on bean-root-nodule number and mass in organic production, was published. The highest nodule number and mass was in the year with a more favorable weather conditions, with a higher humidity. The lowest nodule number was in the method with a direct Tiffi application on the pre-sowing seed, whereas the lowest nodule mass was in the control variety. A positive insignificant correlation was determined between nodule number and mass, and yield. Nodulation was variety dependant. EM application 7 days before sowing, and the combination of Guanito before sowing with EM in flowering, showed a positive impact on nodule number and mass.

The paper discusses the issues of fertilizers effect on germination, plant productivity and overwintering of Kazanskaya 560 variety winter wheat. The results showed that pre-sowing seed treatment by Humate fertilizer “Bioplant Floro” calculated 0.5 liters per ton increases the seed germination to 4-5%, the accumulation of sugars in the tillering nodes of winter wheat to 10-11%, and the safety of overwintering plants to cleaning to 5-10%. The calculated fertilizer norms allow to get close to planned levels of crop during favorable weather conditions. Treating the seeds by “Bioplant Flora”, the yield exceeded the target level (4.1 tons per hectare instead of planned 4 tons per hectare of grain). An application NPK and ammonium nitrate as an ordinal fertilizer at planting provides almost the same level of productivity of the main fertilizers, calculated to produce 3 tons per hectare. It is undesirable to use ammonium nitrate fertilizer on winter wheat as ordinal, especially after steam cleaner with a high nitrogen content. This can reduce its winter hardiness quality. Good results are obtained by using nitrate in the doze 1 centner per hectare in bulk

У статті представлені результати досліджень, проведених протягом 2007–2009, 2014 рр. на дослідному полі ХНАУ ім. В. В. Докучаєва щодо впливу застосування різних строків сівби та норм висіву на варіабельність показників продуктивності колоса різних систем стебел пшениці м’якої озимої сорту Астет. Формування вищих показників продуктивності колоса головної і бічної системи стебел у середньому за роками досліджень забезпечувала сівба 15–17 вересня з нормою висіву 5,0 млн нас./га. Ефективність чинника норми висіву за роками досліджень була більш сталою порівняно зі строками проведення сівби, вплив яких значно залежав від погодних умов веґетаційного періоду конкретного року досліджень. The article presents the results of studies conducted during 2007–2009, 2014 in the experimental field of HNAU named after V. V. Dokuchayev regarding the impact of the application of different sowing date and seeding rates on the variability of  ear productivity indicators of different systems of soft winter wheat stalks of variety Astet. Formation of the highest levels of ear productivity of main and side stems of the average for the year of studies was provided on 15–17 September with the sowing seed rate 5,0 million grains/ha. The effectiveness of the seeding rate by years of research was more stable compared to the timing of sowing, the impact of which is significantly dependent on the weather conditions of the growing season of a particular year.

AbstractIn this paper, we assess whether or not organic agriculture has a positive impact on local economies. We first identify organic agriculture hotspots (clusters of counties with positively correlated high numbers of organic operations) using spatial statistics. Then, we estimate a treatment effects model that classifies a county's membership in an organic hotspot as an endogenous treatment variable. By modeling what a hotspot county's economic indicators would have been had the county not been part of a hotspot, this model captures the effect of being in a hotspot on a county's economic indicators. We perform the same analysis for general agricultural farm hotspots to confirm that the benefits associated with organic production hotspots are, in fact, due to the organic component. Our results show that organic hotspot membership leads to a lower county-level poverty rate and a higher median household income. A similar result is not found when investigating the impact of general agriculture hotspots. On the other hand, our result is robust to alternative hotspot definitions based on type of organic operations to alternative methods of estimating average treatment effects on the treated. These results provide strong motivation for considering hotspots of organic handling operations, which refers to middlemen such as processors, wholesalers and brokers, and hotspots of organic production to be local economic development tools, and may be of interest to policymakers whose objective is to promote rural development. Our results may incentivize policymakers to specifically focus on organic development, rather than the more general development of agriculture, as a means to promote economic growth in rural areas, and may further point them in the direction of not only encouraging the presence of organic operations, but of fostering the development of clusters or hotspots of these operations.

Kłodzko Land is one of the most important regions of Poland in terms of tourism and health issues. Numerous tourism attractions and health resorts make the region attractive for both tourist and bathers. The goal of this paper was to evaluate the impact of weather conditions on tourism-related conditions and their changes in the multiannual period. In the analysis, the indices of heat days, the UTCI (Universal Thermal Climate Index) and CTIS (Climate Tourism Information Scheme) tools were used. The research on heat days and the UTCI indicated a significant increase in the heat-stress frequency over the last decades. Simultaneously, the number of weather types related to cold stress has considerably decreased. Such trends were noticed in the entire region, in all the considered hypsometric zones. The rising tendency was also observed for strong and very strong heat stress (UTCI > 32 °C), which negatively affects health problems. The analysis showed that the most extreme thermal and biothermal conditions, in terms of heat stress, occur under southern and eastern anticyclonic circulation. The CTIS analysis showed that favorable weather conditions for most of tourism activities are noticed in the warm half-year. The usefulness of weather conditions for tourism can vary depending on atmospheric circulation.

AbstractObjectiveTo examine the impacts on food and nutrition-related outcomes resulting from participation in urban gardens, especially on healthy food practices, healthy food access, and healthy food beliefs, knowledge and attitudes.DesignThe systematic review identified studies by searching the PubMed, ERIC, LILACS, Web of Science and Embase databases. An assessment of quality and bias risk of the studies was carried out and a narrative summary was produced.SettingStudies published as original articles in peer-reviewed scientific journals in English, Spanish or Portuguese between 2005 and 2015 were included.SubjectsThe studies included were based on data from adult participants in urban gardens.ResultsTwenty-four studies were initially selected based on the eligibility criteria, twelve of which were included. There was important heterogeneity of settings, population and assessment methods. Assessment of quality and bias risk of the studies revealed the need for greater methodological rigour. Most studies investigated community gardens and employed a qualitative approach. The following were reported: greater fruit and vegetable consumption, better access to healthy foods, greater valuing of cooking, harvest sharing with family and friends, enhanced importance of organic production, and valuing of adequate and healthy food.ConclusionsThematic patterns related to adequate and healthy food associated with participation in urban gardens were identified, revealing a positive impact on practices of adequate and healthy food and mainly on food perceptions.

Transportation systems are central to all cities, and city planners and policy makers take special interest in assuring these systems are efficient, functional, sustainable, and, increasingly, that they have a positive impact on human health. In addition, vehicular emissions are increasingly costly to cities due to congestion and its impact on public health. This study aims to show the associations between the media and environmental variables and associated transit ridership. By tracking media influence, we illustrated how media coverage and attention to an issue over time may impact public opinion and ridership outcomes, especially at the local level where the issues are most salient. The relationship between air quality and transit ridership shown can be generally explained through a combination of infrastructure and human behavior. The media key terms examined in this analysis show that ridership is associated with favorable weather conditions and air quality, suggesting that ridership volume may be influenced by an overall sense of comfort and safety. Based on this analysis, we illustrated the role of media attention in both increased and decreased transit ridership and how such effects are compounded by air quality conditions (e.g., green, yellow, orange, and red air quality days).

Aim. To determine the impact of long-term effect of the complex of factors (anthropogenic and climatic) on the soil fertility, the change in the phytocenosis of weeds and the productivity of winter rye at permanent cultivation. Methods. The content of nitrogen in soil was defi ned by Kornfi eld’s method, phosphorus and potassium – according to Chirikov; the content of non-organic chemical elements in the soil – by ICP-MS method using the emission mass-spectrometer Agilent-7700 × (USA). Results. It was determined that the average productivity of winter rye in 1884–2016 was 1.19 t/ha, but the level of crop productivity fl uctuated depending on the favorable weather conditions of the year, the quality of soil preparation and the content of productive moisture in the cultivated soil layer during sowing, and the weediness of the experimental sowing. Conclusions. The results of the studies may be used to solve the fundamental issues of agriculture, for comprehensive complex investigations, the demonstration of the role of the main factors and conditions of vegetative life.

Abstract. Background: Worldwide prevalence of peripheral artery disease (PAD) is increasing and peripheral vascular intervention (PVI) has become the primary invasive treatment. There is evidence that multidisciplinary team decision-making (MTD) has an impact on in-hospital outcomes. This study aims to depict practice patterns and time changes regarding MTD of different medical specialties. Methods: This is a retrospective cross-sectional study design. 20,748 invasive, percutaneous PVI of PAD conducted in the metropolitan area of Hamburg (Germany) were consecutively collected between January 2004 and December 2014. Results: MTD prior to PVI was associated with lower odds of early unsuccessful termination of the procedures (Odds Ratio 0.662, p < 0.001). The proportion of MTD decreased over the study period (30.9 % until 2009 vs. 16.6 % from 2010, p < 0.001) while rates of critical limb-threatening ischemia (34.5 % vs. 42.1 %), patients´ age (70 vs. 72 years), PVI below-the-knee (BTK) (13.2 % vs. 22.4 %), and rates of severe TASC C/D lesions BTK (43.2 % vs. 54.2 %) increased (all p < 0.001). Utilization of MTD was different between medical specialties with lowest frequency in procedures performed by internists when compared to other medical specialties (7.1 % vs. 25.7 %, p < 0.001). Conclusions: MTD prior to PVI is associated with technical success of the procedure. Nonetheless, rates of MTD prior to PVI are decreasing during the study period. Future studies should address the impact of multidisciplinary vascular teams on long-term outcomes.

The Impact

Based on cross-country panel regressions, the paper analyzes the impact of external currency exposures on monetary policy, exchange rate regime and capital controls. It is determined that positive net external position (which, e.g., is the case for Russia) is associated with a higher degree of monetary policy autonomy, i.e. the national key interest rate is less responsive to Fed/ECB policy and exchange rate fluctuations. Therefore, the risks of cross-country synchronization of financial cycles are reduced, while central banks are able to place a larger emphasis on their price stability mandates. Significant positive impact of net external currency exposure on exchange rate flexibility and financial account liberalization is only found in the context of static models. This is probably due to the two-way links between incentives for external assets/liabilities accumulation and these macroeconomic policy tools.

The purpose of this study is to evaluate the impact of public investment programs on the socio-economic development of territories. As a case, the federal target programs for the development of regions and investment programs of the financial development institution — Vnesheconombank, designed to solve the problems of regional development are considered. The impact of the public interventions were evaluated by the “difference in differences” method using Bayesian modeling. The results of the evaluation suggest the positive impact of federal target programs on the total factor productivity of regions and on innovation; and that regional investment programs of Vnesheconombank are improving the export activity. All of the investments considered are likely to have contributed to the reduction of unemployment, but their implementation has been accompanied by an increase in social inequality.
