Examining the impact of visa restrictions on international tourist flows using panel data: Un análisis con datos de panel
2016
Using newly panel data on visa restrictions for the years 2000 and 2010 in a theory-grounded gravity model, we find a robust, causal negative impact of visa restrictions on international tourist flows. By destination, the detrimental impact of this type of barrier is observed for tourists going to developing countries (with the exception of East and South Asia), but not for those to developed ones. By country of origin of tourists, the impact of visa restrictions appears to be the same for tourists coming from developed and developing countries. These findings have important consequences in policy terms for tourism management at a regional level.
Acute Cardiovascular Responses after a Single Bout of Blood Flow Restriction Training.
2018
Different types of exercise might produce reductions in blood pressure (BP). One physiological mechanism that could explain the lowering adaptation effect on BP after an exercise program is an improved in baroreflex control of muscle sympathetic nerve activity. Consequently, exploring the different methods of training and their post-exercise hypotension (PEH) becomes of interest for healthcare providers. Recently, it has been suggested that blood flow restriction training (BFR) can generate PEH. The aim of this study was to determine the acute response on cardiovascular variables after low intensity resistance training with BFR in normotensive subjects. Twenty-four male (24.38±3.88 years) p…
Restrictions for reimbursement of interferon-free direct-acting antiviral drugs for HCV infection in Europe
2018
All-oral direct-acting antiviral drugs (DAAs) for hepatitis C virus, which have response rates of 95% or more, represent a major clinical advance. However, the high list price of DAAs has led many governments to restrict their reimbursement. We reviewed the availability of, and national criteria for, interferon-free DAA reimbursement among countries in the European Union and European Economic Area, and Switzerland. Reimbursement documentation was reviewed between Nov 18, 2016, and Aug 1, 2017. Primary outcomes were fibrosis stage, drug or alcohol use, prescriber type, and HIV co-infection restrictions. Among the 35 European countries and jurisdictions included, the most commonly reimbursed …
The fnr Gene of Bacillus licheniformis and the Cysteine Ligands of the C-Terminal FeS Cluster
1998
Many of the O2-responsive gene regulators of bacteria are members of the fumarate nitrate reductase-cyclic AMP receptor protein family of transcriptional regulators (12, 13, 15, 17) with predicted structures similar to those of the cyclic AMP receptor protein (11). The Fnr (stands for fumarate nitrate reductase regulator) protein from Escherichia coli (FnrEc) controls the expression of a variety of genes, mainly of anaerobic respiration and metabolism (5, 13). It contains a N-terminal cluster of three essential cysteine residues which are supposed to bind together with Cys122 a [4Fe 4S]2+ cluster which is required for O2 sensing (4, 7, 8, 10, 16). A wide variety of gram-negative bacteria co…
Self-enforcing international environmental agreements revisited
2004
In Barrett's (1994) paper on transboundary pollution abatement is shown that if the signatories of an international environmental agreement act in a Stackelberg fashion, then, depending on parameter values, a self-enforcing IEA can have any number of signatories between two and the grand coalition. Barrett obtains this result using numerical simulations and also ignoring the fact that emissions must be non-negative. Recent attempts to use analytical approaches and to explicitly recognize the non-negativity constraints have suggested that the number of signatories of a stable IEA may be very small. The way such papers have dealt with non-negativity constraints is to restrict parameter values…
Sophisticated humor against Covid: the Polish case
2021
The analysis undertaken in the article focuses on a group of memes selected from the database which drew on culture-specific references. Specifically, they embrace the memories of socialist times and call on references to comic films and easily recognized characters in order to bring out the re-discovered absurdity of the current Covid situation. This material seems ideal to revisit Raskin’s early notion of sophistication, which was broadly argued to derive from intertextuality as well complexity of references that function as sources of humor. In all the examples discussed we can observe the intertextual and metatextual elements, multiple levels and shifts in points of view and attitudes a…
Poola intertekstuaalsed meemid COVID pandeemia kohta
2021
The aim of the paper is to show the Polish story of the COVID-19 pandemic as seen through a humorous looking glass. Different stages of coronavirus presence in the media and social discourse have been accompanied by the appearance and development of jokes and memes, which illustrate the rapidly changing pandemic situation. The database consists of over three hundred memes, movies,and comments collected between February and May 2020, during the pandemic humour peak, and come mainly from private WhatsApp and Facebook accounts of the researchers. The humorous material is related to introduced restrictions, changing laws, parliamentary elections, news from other affected countries as well as se…
Klauzula wyłączności branży w umowie najmu lokalu w centrum handlowym
2019
The article deals with the issue of admissibility and validity of including a clause in a lease agreement. As part of this clause the lessor agrees to give the lessee, on certain conditions, the exclusivity right to conduct a specific type of business activities within the whole area of the shopping centre. The clause can be defined as an industry exclusivity clause. Antimonopoly regulations introducing bans on agreements restricting competition and exceptions to this rule have been analysed.
FETAL GROWTH RESTRICTION: A GROWTH PATTERN WITH FETAL, NEONATAL AND LONG-TERM CONSEQUENCES
2019
Fetal growth restriction (FGR) or intrauterine growth restriction (IUGR) are the terms used for a fetus which has not attained its full growth potential for gestational age. FGR is a multifactorial syndrome responsible for increased fetal and neonatal morbidity and mortality as well as long term adverse outcomes involving auxological, metabolic, organic and functional domains. Clinicians distinguish early and late onset FGR, in relation to specific fetal anthropometric parameters related to the possible primary etiology and to different patterns of placental and maternal cardiovascular pathologies. Delivery of an early onset FGR or growth impaired newborn with congenital pathology should be…
