The aim of the study was to assess the influence of corvid urban roosts on the abundance of two groups of soil mesofauna: mites and springtails. Two areas located in the city of Warsaw were taken into consideration, one subjected to winter roosting activity of corvids and the other not influenced by birds. The samples were taken three times, in May, July, and September of 2013. The results show a positive effect of corvid roosts on the density of soil mesofauna, especially in the top 0–5 cm soil layer. On each sampling date, we found more numerous communities of mites and springtails in the soil within the roosting area than in control. The average densities ofmites ranged from 30×103 ind. m–2 to 200×103 ind. m–2 in the soil within the roost and from 6 ×103 ind. m–2 to 40×103 ind. m–2 in the control. In the case of springtails the average densities ranged from 9×103 ind. m–2 to 36×103 ind. m–2 in the roost and from 4×103 ind. m–2 to 8×103 ind. m–2 in the control. Among the two groups, mites prevailed over the springtails both in the soil of roost and control area. We inferred that the corvid roosting activity, involving mainly an excrement deposition on the soil surface, influences soil mesofauna indirectly

Many applications have relied on the hedonic pricing model (HPM) to measure the willingness-to-pay (WTP) for urban externalities and natural disasters. The classic HPM regresses housing price on a complete list of attributes/characteristics that include spatial or environmental amenities (or disamenities), such as floods, to retrieve the gradients of the market (marginal) WTP for such externalities. The aim of this paper is to propose an innovative methodological framework that extends the causal relations based on a spatial matching difference-in-differences (SM-DID) estimator, and which attempts to calculate the difference between sale price for similar goods within “treated” and “control” groups. To demonstrate the potential of the proposed spatial matching method, the researchers present an empirical investigation based on the case of a flood event recorded in the city of Laval (Québec, Canada) in 1998, using information on transactions occurring between 1995 and 2001. The research results show that the impact of flooding brings a negative premium on the housing price of about 20,000$ Canadian (CAN).

To practice strength and balance activities are shown as useful tools to fall prevention by diverse metanalysis. On the other side, aquatic environment offers interesting properties for a therapeutic reeducation, being the Ai Chi one of its applications. Aim: To evaluate the repercussion of an Ai Chi programme on aged people’s balance. Method: A randomized controlled trial was developed comparing two groups formed by aged people with risk of fall according to the Timed Up & Go test. Intervention Group (IG) followed twelve Ai Chi sessions combined with their thermal programme; and Control Group (CG) just followed the thermal programme. Both groups spent two weeks in the Balneario of Archena (Murcia, Spain). Results: Both groups improve their balance; however, only the IG reached the non-risk of fall from the Timed Up & Go test. Conclusions: The combination of Ai Chi sessions and a thermal programme had a positive effect on aged people’s balance, showing a therapeutic and clinical relevance.

AbstractObjective:To determine the impact of three needleless intravenous systems on needlestick injury rates.Design:Randomized controlled trial.Setting:1,000-bed tertiary-care Midwestern hospital.Participants:Nursing personnel from general medical, general surgical, and intensive-care units.Interventions:From June 1992 through March 1994, a metal blunt cannula (MBC), two-way valve (2-way), and plastic blunt cannula (PBC) were introduced into three study areas, and needlestick injury rates were compared to three control areas using traditional needled devices.Results:24 and 29 needlestick injuries were reported in study and control areas. Intravenous-therapy-related injuries comprised 45.8% and 57.1% of injuries in each area. Thirty-seven percent and 20.7% of study and control area needlestick injuries were considered to pose a high risk of bloodborne infection. The 2-way group had similar rates of total and intravenous-related needlestick injuries compared to control groups. The PBC group had lower rates of total and intravenous-related needlestick injuries per 1,000 patient-days (rate ratios [RR], 0.32 and 0.24; 95°% confidence intervals [CI95], 0.12-0.81 and 0.09-0.61;P=.02 andP=.003, respectively) and per 1,000 productive hours worked (RR, 0.11 and 0.08; CI95, 0.01-0.92 and 0.010.69;P=.03 andP=.005, respectively) compared to controls.Conclusions:Needlestick injuries continued in study areas despite the introduction of needleless devices, and risks of bloodborne pathogen transmission were similar to control areas. The PBC device group noted lower rates of needlestick injuries compared to controls, but there were problems with product acceptance, correct product use, and continued traditional device use in study areas. Low needlestick injury rates make interpretations difficult. Further studies of safety devices are needed and should attempt greater control of worker behavior to aid interpretation.

Abstract The article presents an attempt to analyse population changes and to measure the strength of the impact of factors causing these changes in former voivodeship (province) cities in Poland. In view of the ongoing processes of suburbanisation, the discussion also concerns the areas surrounding the city, i.e. those creating urban systems together with the city. These zones were delineated, calling them demographic influence zones, because only demographic factors were involved in defining them. The research was conducted in the period between1999–2015, and took into account the administrative reform of the country that degraded 31 cities from voivodeship (NUTS-2) capitals to poviat (LAU-1) cities. The main aim of the study was to find an answer to the question: do the directions and the strength of population changes confirm a hypothesis of the destructive impact of the loss of administrative function on settlement units. The results of the study only partially confirmed this hypothesis. Although a decrease in the population is overwhelmingly predominant in the city core, in the case of the demographic influence zone, it has already increased. Counting both parts together, it was found that in half of the cases there was a decline and in the other half a growth of the population.

It is precisely in the course of adjusting the activities of these subjects, the main task of state regulation of the bankruptcy institute is the formation of such conditions for the functioning of the national economy, which will reduce the risk of doing business for all its entities and promote the internal reorganization of its structure in accordance with the requirements of global transformations. The system of indicators describing the situation in a certain area of ​​the functioning of national economic entities allows us to determine, directly or indirectly, the effectiveness of the bankruptcy institute at the macro-level. To analyze the impact of each of the factors on GDP, a sensitivity analysis was conducted according to which input data X were recorded at the values ​​of 2018 and alternately changed by 10%. For each such change, GDP was calculated as compared to the model value for 2018. As a result of the calculations, the most sensitive factors were identified and features of the functioning of the bankruptcy institute in the Ukrainian economy were identified. The main provisions of a state policy aimed at increasing the functional effectiveness of the bankruptcy institute are formulated. First of all, it is necessary to promote the country's position in the Doing business rankings, as well as the Indexes of Economic Freedom and Corruption Perceptions. On the other hand, an annual growth of the inflation index of around 10% and the level of the fiscal tax burden will also have a positive effect on GDP dynamics.

ABSTRACT: The objective of this work was to conduct a temporal evaluation of incidence of rot base and sanitary severity, and to relate the impact on the seed pathology of common bean cultivars. In the 2015-2016 harvest, in the city of Ipameri, Goiás, ten cultivars of common bean were evaluated (BRS Estilo©, BRS Pérola©, IPR Tangará©, IPR Tuiuiú©, IPR Uirapuru©, IAC Milênio©, Imperador©, IAC F3 R2©, IAC OTG© and IPR Campos Gerais©) and distributed into five blocks, totaling 40 experimental units. The incidence of wilt and base rot and sanitary severity were analyzed by taking ten random samples per block at 21, 28, 56, 63 and 69 days after planting. At the end of 120 days, a total of 20 plants were harvested per cultivar, and 250 seeds were harvested for application of the Blotter Test method. From 21 to 69 days after planting, the cultivars BRS Pérola© and IPR Campos Gerais© deserve to be highlighted for presenting the lowest incidence of wilt in the reproductive and vegetative cycles. The cultivar BRS Pérola© showed the lowest incidence of wilt and sanitary severity. In the analysis of harvested seeds, the cultivar BRS Pérola© presented high physiological quality for all evaluated parameters. On the other hand, Cramberry (OTG)© showed low physiological potential in germination and vigor tests.

The aim of this work was to study whether feeding a methanogen inhibitor from birth of goat kids and their does has an impact on the archaeal population colonizing the rumen and to what extent the impact persists later in life. Sixteen goats giving birth to two kids were used. Eight does were treated (D+) with bromochloromethane after giving birth and over 2 months. The other 8 goats were not treated (D−). One kid per doe in both groups was treated with bromochloromethane (k+) for 3 months while the other was untreated (k−), resulting in four experimental groups: D+/k+, D+/k−, D−/k+, and D−/k−. Rumen samples were collected from kids at weaning and 1 and 4 months after (3 and 6 months after birth) and from does at the end of the treating period (2 months). Pyrosequencing analyses showed a modified archaeal community composition colonizing the rumen of kids, although such effect did not persist entirely 4 months after; however, some less abundant groups remained different in treated and control animals. The different response on the archaeal community composition observed between offspring and adult goats suggests that the competition occurring in the developing rumen to occupy different niches offer potential for intervention.

AbstractThis article assesses the sociolinguistic impact and importance of the other articles in this special issue on Paris, considering three main themes that are evoked. First, the contribution of the articles here to the development of work on language variation and change on Hexagonal French within the variationist paradigm. Second, I address what I see as the important contribution made to our understanding of the ‘city’ as a sociolinguistic site. Finally, I focus on ethnicity as a social construct in recent variationist work in cities and consider what the articles here, and in comparison with cities elsewhere, add to our understanding of the impact of immigration on local manifestations of language variability. In each case, I attempt to show how these articles foreground or even problematize these three issues, and provide a prospectus for further research that can address unresolved questions.

Recently, negative effects of the blasting operations and quantification of the seismic safety are regarded as very important technical problem in quarries. The impact of blasting operations is accompanied by both positive and negative seismic effects. For example, vibrations generated by explosion create very positive effect − when help to break the rocks, but, on the other hand, also result in negative effect − when affect constructions and natural environment in the vicinity of a blasting works site. If the vibrations are large enough, then the nearby objects could be damaged or destroyed. This article highlights the results of the blasting operation monitoring in limestone Lopušné Pažite quarry on Slovakia, which based on the rule that the negative effects depend on their range and strength. This method is applied in all quarries in Slovakia, which are close to settlements.
