Outsourcing under Threat: Estimated Impact of Potential Tariffs on US Imports from Mexico
2017
In this paper, I discuss the effects of certain trade policy measures, mostly import tariffs, presently contemplated by the US government, aimed at enhancing domestic employment in a number of targeted industries. I intend to show that insofar as such measures restrain free trade among NAFTA member-countries, they run counter to a basic rule suggested by conventional theory, stating that, following changes in the tariff structure, resources will shift toward activities that enjoy the highest rate of effective protection. I try to demonstrate that erecting barriers against inside-NAFTA trade, aside from hurting industries that use outsourcing extensively, has little chances to create incenti…
Enhancing a Transition to a Circular Economy in the Water Sector: The EU Project WIDER UPTAKE
2021
A novel approach for resource recovery includes forward osmosis (FO) as a concentration step in municipal wastewater treatment. The current study investigates different pre-treatment strategies including biological treatment with a moving-bed bioreactor (MBBR) at different loading rates and particle removal by filtration and sedimentation. Membrane performance and recovery potential for energy and nutrients were investigated in laboratory-scale FO experiments in batch mode using pre-treated municipal wastewater as feed and 35 g/L NaCl as a draw solution. Initial water fluxes were in the range of 6.3 to 8.0 L/(m2·h). The baseline fluxes were modelled to account for flux decline due to concen…
Mung Bean nuclease mapping of RNAs 3' end
2009
Abstract A method is described that allows an accurate mapping of 3' ends of RNAs. In this method a labeled DNA probe, containing the presumed 3' end of the RNA under analysis is allowed to anneals to the RNA itself. Mung-bean nuclease is then used to digest single strands of both RNA and DNA. Electrophoretic fractionation of "protected" undigested, labeled DNA is than performed using a sequence reaction of a known DNA as length marker. This procedure was applied to the analysis of both a polyA RNA (Interleukin 10 mRNA) and non polyA RNAs (sea urchin 18S and 26S rRNAs). This method might be potentially relevant for the evaluation of the role of posttrascriptional control of IL-10 in the pat…
Working with children who are victims of abuse: Emotions and representations of professionals in residential children's communities
2020
Professionals who work in residential children’s communities face many difficulties and, when the hosted children have a history of abuse and maltreatment, the risk of vicarious traumatization and professional burn-out, which has a negative effect on the professional’s work and well-being as well as on the effectiveness at work, is very high.This qualitative study aims to explore, via the content analysis of text recorded in some Photolangage® groups, the representations of social workers and educators in residential children’s communities on the theme of work management of physical and sexual abuse victims. The participants were 37 social workers from 6 residential communities for 0-6 year…
Natural assets in the right-of-way of A-4 Motorway in the Góra Świętej Anny Landscape Park, Opole Region
2014
Construction of the A-4 Motorway section in the Opole Region begun in Summer 1997. Very soon vigorous resistance of ecological NGOs was encountered. The bone of contention was the section of motorway that passes through the Góra Świętej Anny Landscape Park and verges the natural reserve of strict protection Ligota Dolna where rare species of thermophilic plants are sheltered. Between 2011 and 2013 a detailed mycological, geobotanical, floristic and fauna research took place within the right-of-way of the A-4 Motorway section crossing the Góra Świętej Anny Landscape Park in the Opole Region. The survey revealed several rare and protected species of fungi, plants and animals along the road, i…
Computational Criteria for Hydrogen Evolution Activity on Ligand-Protected Au25-Based Nanoclusters
2023
The hydrogen evolution reaction (HER) is a critical reaction in addressing climate change; however, it requires catalysts to be generated on an industrial scale. Nanomaterials offer several advantages over conventional HER catalysts, including the possibility of atomic precision in tailoring the intrinsic activity. Ligand-protected metal clusters, such as the thiolate-protected MAu24(SR)18 (where M is Au, Cu, Pd), are of particular interest as not only are they electrocatalytically active toward HER, but the charge state and composition can be precisely tuned. Here, we present a comprehensive computational study examining how the charge state and dopants affect the catalytic activity of [MA…
On the distribution of lightning current among interconnected grounding systems in medium voltage grids
2018
This paper presents the results of a first investigation on the effects of lightning stroke on medium voltage installations' grounding systems, interconnected with the metal shields of the Medium Voltage (MV) distribution grid cables or with bare buried copper ropes. The study enables us to evaluate the distribution of the lightning current among interconnected ground electrodes in order to estimate if the interconnection, usually created to reduce ground potential rise during a single-line-to-ground fault, can give place to dangerous situations far from the installation hit by the lightning stroke. Four different case studies of direct lightning stroke are presented and discussed: (1) two …
Local support for conservation is associated with perceptions of good governance, social impacts, and ecological effectiveness
2019
Local support is important for the longevity of conservation initiatives. The literature suggests that perceptions of ecological effectiveness, social impacts, and good governance will influence levels of local support for conservation. This paper examines these relationships using data from a survey of small-scale fishermen in 11 marine protected areas from six countries in the Mediterranean Sea. The survey queried small-scale fishermen regarding perceptions and support for conservation. We constructed composite scores for three categories of perceptions-ecological effectiveness, social impacts, and good governance-and tested the relationship with levels of support using ordinal regression…
