Regional Demographic Differences: the Effect of Laestadians
Laestadianism, a conservative revival movement inside the Lutheran church, has an estimated 100,000 followers in Finland. Laestadians have characteristics differing from the followers of the mainstream state church in areas such as religious activity, regional concentration, fertility and family planning, but these are generally not quantified due to lack of easily accessible data. This study highlights the importance of including location and religiosity, and not only religious affiliation in the study of fertility behaviour. The research uses statistical tools to study the correlations between such variables as religious density and total fertility rate. It is found that on the regional level, the total fertility rate and the increasing number of small children in the family is positively associated with the proportion of Laestadians. The regional variation of religiousness, and the subsequent effects on population structure and socioeconomics are discussed
Beyond academia – interrogating research impact in the Research Excellence Framework
Big changes to the way in which research funding is allocated to UK universities were brought
about in the Research Excellence Framework (REF), overseen by the Higher Education
Funding Council, England. Replacing the earlier Research Assessment Exercise, the purpose of
the REF was to assess the quality and reach of research in UK universities – and allocate
funding accordingly. For the first time, this included an assessment of research ‘impact’,
accounting for 20% of the funding allocation. In this article we use a text mining technique to
investigate the interpretations of impact put forward via impact case studies in the REF process.
We find that institutions have developed a diverse interpretation of impact, ranging from
commercial applications to public and cultural engagement activities. These interpretations of
impact vary from discipline to discipline and between institutions, with more broad-based
institutions depicting a greater variety of impacts. Comparing the interpretations with the score
given by REF, we found no evidence of one particular interpretation being more highly rewarded
than another. Importantly, we also found a positive correlation between impact score and
[overall research] quality score, suggesting that impact is not being achieved at the expense of
research excellence
Report on methods for demographic projections at multiple levels of aggregation
This report describes methods of internal consistency in population projections at multiple levels of aggregation. The first step in the process is to make the initial assumptions used in the projections at different levels of aggregation consistent. This input-level consistency can be further enhanced by output-level analysis. Comparing the results at the relevant levels of aggregation ensures internal consistency at the output level. Thus, we are able to compare the differences in the age and sex distribution of the population and specific demographic indicators (such as the old age dependency ratio) over various regional levels.
In PLUREL, the national projections will be carried out using the probabilistic method while the regional projections will use deterministic or variant methods. The results at these two levels of aggregation cannot be directly compared one-to-one as there is no simple correspondence between the output variants and the probabilistic range. To avoid any problems arising from this, we develop an index representing the differences in the size and distribution of the population from the variant method to a given percentile in the probabilistic population estimate.
The report discusses various population projection techniques together with their strengths and weaknesses. The relative advantage of specific models for different purposes is discussed forming a selection of models to be used for the population projections in PLUREL: National (NUTS1-0), Regional (NUTS-2) and Case Study Projections (NUTS-5). We conclude that stochastic projections are best suited for national projections, while classic or multiregional cohort-component model projections are likely to be the best choice for the regional projections and for the detailed case study projections
Enhanced dielectrophoresis of nanocolloids by dimer formation
We investigate the dielectrophoretic motion of charge-neutral, polarizable
nanocolloids through molecular dynamics simulations. Comparison to analytical
results derived for continuum systems shows that the discrete charge
distributions on the nanocolloids have a significant impact on their coupling
to the external field. Aggregation of nanocolloids leads to enhanced
dielectrophoretic transport, provided that increase in the dipole moment upon
aggregation can overcome the related increase in friction. The dimer
orientation and the exact structure of the nanocolloid charge distribution are
shown to be important in the enhanced transport
Improved Methods and Metrics for Assessing Impacts, Vulnerability and Adaptation
Over the course of the MEDIATION project, Work Package 2 was tasked with "develop[ing] and apply[ing] a toolbox, defined as a set of models, methods, and metrics for the assessment of impacts and vulnerability and adaptation options." As highlighted in Deliverable 2.2, many frameworks and methods for assessing adaptation have been developed over the last 20 years, yet these often have not been adopted in the context of formal adaptation policies in Europe and elsewhere. Reasons and problems include: (i) a fragmentation of methods and tools, (ii) a lack of linkages to actual policy needs, (iii) a lack of understanding and communication of uncertainties, (iv) the often expert-based nature and complexity of methods used versus actual user demands, and (v) a lack of consistent data, definitions and metrics.
Deliverable 2.2 put forward a rough prototype for a toolbox of methods for studying impacts, vulnerability, and adaptation. In this deliverable, we discuss subsequent work on the MEDIATION toolbox, and report on application and testing of the improved methods and metrics in selected key European sectors and regions.
We present feedback and improvement to methods and metrics based on input from case studies, stakeholders, and focus groups, as well as an overview of case study work and contribution to an improved MEDIATION toolbox. This input resulted in a number of conclusions relating to the development and use of methods and metrics, reducing uncertainty in CCIAV, and led to a number of changes, including the creation of a novel typology for classifying methods and models relating to CCIAV analysis. We provide an overview of the new typology, as well as the final toolbox, and summarize case study contributions towards improved methods and metrics
Dielectrophoresis of nanocolloids: a molecular dynamics study
Dielectrophoresis (DEP), the motion of polarizable particles in non-uniform
electric fields, has become an important tool for the transport, separation,
and characterization of microparticles in biomedical and nanoelectronics
research. In this article we present, to our knowledge, the first molecular
dynamics simulations of DEP of nanometer-sized colloidal particles. We
introduce a simplified model for polarizable nanoparticles, consisting of a
large charged macroion and oppositely charged microions, in an explicit
solvent. The model is then used to study DEP motion of the particle at
different combinations of temperature and electric field strength. In accord
with linear response theory, the particle drift velocities are shown to be
proportional to the DEP force. Analysis of the colloid DEP mobility shows a
clear time dependence, demonstrating the variation of friction under
non-equilibrium. The time dependence of the mobility further results in an
apparent weak variation of the DEP displacements with temperature
