Level of adherence to prescribed exercise in spondyloarthritis and factors affecting this adherence: a systematic review
Adherence is a primary determinant of the effectiveness of any intervention. Exercise is considered essential in the management of spondyloarthritis (SpA); however, the overall adherence to exercise programmes and factors affecting adherence are unknown. The aim of this systematic review was to examine measures of, and factors influencing adherence to, prescribed exercise programmes in people with SpA. A search was performed in August 2018 using five data bases; the Cochrane library, CINAHL, EMBASE, MEDLINE, and Web of Science Collections. Inclusion criteria were: studies with adults (> 18 years) with SpA, with a prescribed exercise intervention or educational programme with the aim of increasing exercise participation. Article quality was independently assessed by two assessors. Extracted descriptive data included: populations, interventions, measures of adherence and factors affecting adherence. Percentage adherence rates to prescribed exercises were calculated if not reported. Nine studies were included with a total of 658 participants, 95% of participants had a diagnosis of ankylosing spondylitis. Interventions and measurement of adherence varied, making comparisons difficult. Rates of adherence ranged from 51.4 to 95%. Single studies identified; adherence improved following educational programmes, and higher disease severity and longer diagnostic delays were associated with higher adherence. Conflicting evidence was found as to whether supervision of exercise improved adherence. Three consecutive studies demonstrated adherence reduced over time. Adherence to prescribed exercise in SpA was poorly reported and predominately for people with AS. The levels of adherence and factors affecting prescribed exercise in SpA remain unclear. Future research should measure adherence across a longer time period and investigate possible factors which may influence adherence
eCHASE: Sustainable Exploitation of Electronic Cultural Heritage
Europe’s digital cultural heritage content has tremendous exploitation potential in applications such as Education, Publishing, e-Commerce, Public Access and Tourism. Value is hugely amplified if the content can be aggregated, repurposed and distributed at a European level. The eCHASE project seeks to demonstrate that public-private partnerships between content holders and commercial service providers can create new services and a sustainable business based on access and exploitation of digital cultural heritage content. This paper describes these issues and introduces the eCHASE architecture that is being developed to showcase the business models created for the project
Marine nematode taxonomy in the DNA age: the present and future of molecular tools to access their biodiversity
Molecular taxonomy is one of the most promising yet challenging fields of biology. Molecular markers such as nuclear and mitochondrial genes are being used in a variety of studies surveying marine nematode taxa. Sequences from more than 600 species have been deposited to date in online databases. These barcode sequences are assigned to 150 nominal species from 104 genera. There are 41 species assigned to Enoplea and 109 species to Chromadorea. Morphology-based surveys are greatly limited by processing speed, while barcoding approaches for nematodes are hampered by difficulties in matching sequence data with morphology-based taxonomy. DNA barcoding is a promising approach because some genes contain variable regions that are useful to discriminate species boundaries, discover cryptic species, quantify biodiversity and analyse phylogeny. We advocate a combination of several approaches in studies of molecular taxonomy, DNA barcoding and conventional taxonomy as a necessary step to enhance the knowledge of biodiversity of marine nematodes
Shifting Patterns in Marks and Registration: France, the United States and United Kingdom, 1870-1970
This paper looks at trademarks and brands, beyond the conventional interests of marketing and law, as a way to explaining the evolution of international business and economies in general. It shows that the perspective defended by many scholars such as Chandler (1990), Wilkins (1991, 1994) and Koehn’ (2001), about the Anglo-Saxon countries, and in particular the United States, leading the transition to modern trade-marks is narrow in its focus. Instead of the United States standing out as historically on the leading edge of innovation in the law and practice of trade marking, it appears from several directions to have been on the trailing edge. France and Britain have a more enduring interest in trademarking. The paper also looks at one particular subset of trade mark registration data – non durable consumer goods. These, and in particular food, are the dominant sectors in the three countries in terms of trademarking, reflecting the character of the sectors where imagery associated with the products is so central in competition. The paper relies on original data from three countries, France, the United Kingdom and the United States, in particular trade mark registrations, and the analysis spans for a period of one hundred years period 1870-1970.trade marks, brands, international business history, intellectual property rights, trademark law
Increasing the Size of a Piece of Popcorn
Popcorn is an extremely popular snack food in the world today. Thermodynamics
can be used to analyze how popcorn is produced. By treating the popping
mechanism of the corn as a thermodynamic expansion, a method of increasing the
volume or size of a kernel of popcorn can be studied. By lowering the pressure
surrounding the unpopped kernel, one can use a thermodynamic argument to show
that the expanded volume of the kernel when it pops must increase. In this
project, a variety of experiments are run to test the validity of this theory.
The results show that there is a significant increase in the average kernel
size when the pressure of the surroundings is reduced.Comment: Latex document, 14 pages, 4 figures, 1 page of table
A Spatial Economic Model and Spatial Econometric Analysis of Population Dynamics in Brazilian MCAs
To extend existing population growth models, this article proposes a theoretical setting including spatial interaction effects. Using data pertaining to 3659 Brazilian Minimum Comparable Areas (MCA) over the period 1970-2010, this extension is tested by estimating a dynamic spatial panel model. The authors also compare the performance of a wide range of potential neighborhood matrices using Bayesian posterior model probabilities. Six of the thirteen determinants of population growth considered produce significant spatial interaction effects. Moreover, five produce significant long-term spatial spillover effects; a mathematical analysis reveals the strength of this result, which requires more than a single parameter. Treating areas as independent entities, as many previous population growth studies have done, underestimates the impact of various policy measures
