Economic growth, income distribution, and poverty in Poland during transition
The authors attempt to analyze the linkages between macroeconomic policies and economic growth variables, their movement over time, and their impact on poverty in the case of Poland. Poland, a middle-income country, is of particular interest because its data sources allow for a relatively detailed analysis of such developments, and the macroeconomic environment and the economic growth variables show a relatively sizable degree of variance. In addition, Poland has struggled in the past few years to reduce poverty while still experiencing positive economic growth. The authors show that in Poland, poverty-reducing growth depends heavily on the ability of the economy to generate jobs. During the early years of transition, net job growth was positive, while after the Russian crisis of 1998, productivity gains were accomplished mostly through labor shedding, henceforth, increasing poverty in Poland. In addition, the authors identify how fiscal and social protection policies affect income distribution and poverty in Poland.Economic Theory&Research,Environmental Economics&Policies,Services&Transfers to Poor,Poverty Impact Evaluation,Economic Conditions and Volatility,Inequality,Governance Indicators,Environmental Economics&Policies,Achieving Shared Growth,Economic Theory&Research
Equilibrium and dynamic moisture adsorption behaviour of bloodmeal based bioplastic
Bioplastics can be manufactured from protein or carbohydrate sources such as wheat gluten, corn, sun flower, keratin, casein, soy, gelatine and whey. A recently developed bioplastic is Novatein thermoplastic (NTP), which is produced from bloodmeal by adding water, urea, sodium sulphite, sodium dodecyl sulphate and tri-ethylene glycol (TEG), allowing it to be extruded and injection moulded. Bioplastics, compared to their petroleum counterparts, can readily adsorb or lose water, which then changes their physical properties such as tensile strength and glass transition temperature. NTP at different TEG and water contents was exposed to 20-85% relative humidity (RH) environments and change in mass recorded over 35 days to determine equilibrium and dynamic moisture adsorption behavior. Equilibrium behavior was modelled using modified Freundlich and Langmuir- Freundlich isotherms, and dynamic behavior modelled using Pilosof, Singh- ulshrestha, exponential, Langmuir-Freundlich and simple rate equations. Excellent fits were obtained for both isotherms and the last three rate equations gave best overall fits for dynamics. NTP adsorbed up to 28% by weight in water at 85% RH, reaching equilibrium within 20 days. Plastics with high TEG had a greater affinity for water but lower water adsorption rates, while dry plastic samples had a lower adsorption rate than wet samples. The two parameter Freundlich model and the exponential or simple rate model is recommended for modelling NTP equilibrium and dynamic water adsorption
Traces of prior art. An analysis of non-patent references found in patent documents.
Research in the area of innovation has pointed out the relevance of conceiving innovation as processes in which a multitude of actors and a variety of interactions play a role. Integrative notions like (national) innovations systems, (techno-scientific) networks, or the triple helix metaphor, have been widely accepted as relevant to grasp the complexities entailed. This development highlights the need for indicators that mirror the dynamics involved. This contribution presents an in-depth examination of the role of 'Non-Patent references', found in patents. After examining the occurrence of these references in the USPTO and EPO patent systems, the precise nature of these references is delineated by means of a systematic content analysis of two samples of non-patent references (n=10.000). Our observations reveal the relevance of 'non-patent references' for developing indicators to depict the proximity of technological and scientific developments. Application areas, limitations and directions for future research are discussed.Academic investors; Field; Industry; Knowledge; Knowlegde interactions; Research; University-industry relations; Working; Area; Innovation; Processes; Innovations; Systems; Networks; Triple-helix; Complexity; Indicators; Dynamics; Patents;
Internationale politieke economie: herijking van de studie naar internationale politiek
Internationale Politieke Economie (IPE) is een nieuw vakgebied dat een zekere integratie voorstaat van Internationale Betrekkingen, Internationale Economische Betrekkingen, Politicologie en Bestuurskunde. Het is een terrein dat zich goed leent om de wisselwerking van verschijnselen op subnationaal, nationaal en internationaal niveau te analyseren. Dit artikel geeft een oeverzicht van de recente ontwikkelingen op dit vakgebied en signaleert de mogelijkheden en beperkingen van IPE
Non-alcoholic fatty liver disease: Current therapeutic options
Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease and has an estimated global prevalence of 25%. NAFLD is found in up to 80% of people with obesity and over 60% of patients with diabetes. Cardiovascular disease is the main cause of mortality, followed by extra-hepatic cancers and then liver-specific complications of cirrhosis and hepatocellular carcinoma. Lifestyle modification remains the primary intervention in NAFLD. Weight loss achieved through dietary modification and exercise can lead to histologic improvement and reversal of metabolic complications. Current drug therapy is limited to pioglitazone and vitamin E; however, several agents are currently under phase III development. This review summarises the current treatment options in NAFLD
Image Classification with the Fisher Vector: Theory and Practice
A standard approach to describe an image for classification and retrieval purposes is to extract a set of local patch descriptors, encode them into a high dimensional vector and pool them into an image-level signature. The most common patch encoding strategy consists in quantizing the local descriptors into a finite set of prototypical elements. This leads to the popular Bag-of-Visual words (BOV) representation. In this work, we propose to use the Fisher Kernel framework as an alternative patch encoding strategy: we describe patches by their deviation from an ''universal'' generative Gaussian mixture model. This representation, which we call Fisher Vector (FV) has many advantages: it is efficient to compute, it leads to excellent results even with efficient linear classifiers, and it can be compressed with a minimal loss of accuracy using product quantization. We report experimental results on five standard datasets -- PASCAL VOC 2007, Caltech 256, SUN 397, ILSVRC 2010 and ImageNet10K -- with up to 9M images and 10K classes, showing that the FV framework is a state-of-the-art patch encoding technique
Trace checking of Metric Temporal Logic with Aggregating Modalities using MapReduce
Modern complex software systems produce a large amount of execution data,
often stored in logs. These logs can be analyzed using trace checking
techniques to check whether the system complies with its requirements
specifications. Often these specifications express quantitative properties of
the system, which include timing constraints as well as higher-level
constraints on the occurrences of significant events, expressed using aggregate
operators. In this paper we present an algorithm that exploits the MapReduce
programming model to check specifications expressed in a metric temporal logic
with aggregating modalities, over large execution traces. The algorithm
exploits the structure of the formula to parallelize the evaluation, with a
significant gain in time. We report on the assessment of the implementation -
based on the Hadoop framework - of the proposed algorithm and comment on its
scalability.Comment: 16 pages, 6 figures, Extended version of the SEFM 2014 pape
