Frozen blood samples from 13 species of free-ranging birds (n = 65) and captive Chilean flamingos (Phoenicopterus chilensis) (n = 46) housed outdoors in the Chicago area were screened for Plasmodium. With the use of a modified polymerase chain reaction, 20/65 (30.8%) of free-ranging birds and 26/46 (56.5%) of flamingos were classified as positive for this parasite genus. DNA sequencing of the p...

awareness of the perception of farmers toward cooperation is an important step for developing the role of cooperatives in rural economy. the purpose of this descriptive-correlational study was to investigate perception of farmers toward cooperation. the statistical population for the study consisted of farmer heads of families in the rural society of kermanshah township (n=24391). three hundred...

This paper aims to assess the current and potential role of UNESCO Transboundary Biosphere Reserves (TBRs) as a platform for cross-border-cooperation-enhancing sustainable development border areas characterised by unique natural cultural heritage but lagging in socio-economic terms. The study covered three TBRs located Polish–Ukrainian borderland: West Polesie, Roztocze East Carpathians. quanti...

The Chilean saline lakes are distributed mainly in the Atacama desert in northern Chile and the southern Patagonian plains. The scarce studies are restricted mainly to northern Chilean saline lakes, and these revealed that the main component in these ecosystems are the halophylic copepod Boeckella poopoensis Marsh 1906, or the brine shrimp Artemia franciscana (Kellog, 1906), and both species do...

Despite a great deal of evidence that corporal punishment is harmful, corporal punishment is still very prevalent worldwide. We examine predictors of different types of corporal punishment among Ukrainian mothers in 12 communities across Ukraine. Findings suggest that maternal spirituality, maternal coping styles, family communication, and some demographic characteristics are predictive of moth...

This paper estimates the effect of domestic and foreign privatization on multifactor productivity (MFP) using long panel data for nearly the universe of initially state-owned manufacturing firms in Ukraine. The longitudinal dimension of the data is used to measure and control for pre-privatization selection bias and to estimate long-run impacts. The data imply steadily increasing MFP as a resul...

There are previously reported data describing differences between Asian and European patients with Myelodysplastic Syndromes (MDS), few direct comparisons based on cancer registration characteristics or using cohorts to validate scoring systems. This is the first study from South-America, which attempts to describe demographic, clinical features, and outcome of MDS patients. We retrospectively ...

There are d-dimensional zonotopes with n zones for which a 2-dimensional central section has Ω(nd−1) vertices. For d = 3 this was known, with examples provided by the “Ukrainian easter eggs” by Eppstein et al. Our result is asymptotically optimal for all fixed d ≥ 2.
