Affinity Programs and the Real Estate Brokerage Industry
This study surveys active real estate brokers obtaining information on involvement in affinity programs and referral/relocation networks. Some results regarding affinity involvement are: (a) 13% of respondents reported affinity affilliations, 75% reported no affiliations, and 12% indicated plans to become involved within the next year; (b) about half having affinity affiliations were involved with 2-4 groups; (c) affinity relationships were most often with membership organizations, corporations, and professional organizations; (d) the primary affinity benefits provided were commission reductions, special mortgage packages, and discounted closing services; (e) 38% of respondents reported an increase in profitability die tp affinity affiliation while 21% reported a decrease; and (f) 56% reported an increase in agent productivity. An empirical income model shows that affinity affiliation has a positive effect on broker income. The probit models shows that: (a) participation in affinity arrangements is more likely for larger firms and national franchises but is not sensitive to location; and (b) large firms are more likely to participate in a larger number of affinity relationships.
Experiences and choices: A battle of the habitus - working class pupils and positive outcomes
The importance of supporting and acknowledging the potential barriers young people from socially disadvantaged areas face has always been of importance in educational research and policy in Scotland, and the UK; for example through the Scottish Government’s Attainment Challenge and the work of the Joseph Rowntree Foundation. This research aims to understand young people’s aspirations from the lens of Bourdieu’s Theory of Reproduction, in particular his concept of habitus and its associated dispositions. This research develops the work on aspirations in relation to understanding how factors such as family, school and social class influence young people’s habitus, dispositions and aspirations. A clear link is found between a young person’s primary habitus and the role of the school in transforming this habitus. Furthermore, this research also contributes to literature and knowledge on using Bourdieu’s theory as method, where a unique approach to using Bourdieu’s concepts is developed to give a theoretical, methodological lens with which to analyse data under three high-level themes: dispositions, educational field and doxic, habituated and emergent aspirations. This research finds that it is possible for a young person to move between these types of aspirations and that the school and its associated partners are key in transforming young people’s habitus by using the school’s institutional habitus and opportunities offered by Developing the Young Workforce policy in Scotland. Various example of good practice are identified where this has been successful and key recommendations in relation to supporting youth transitions are made in relation to ways the school can support young people to transform their habitus, should this be appropriate for individual young people. This is demonstrated through one participant whose habitus was transformed in order to achieve his goals.
This research is situated within an interpretivist paradigm, focusing on quantitative methods, considering liberal and neoliberal influences on policy and education. The above aims are achieved through one-to-one semi-structured interviews using pre-prepared vignettes, involving young people aged 16-17 years old from a school in Glasgow where over 90% of the pupil population and their families live in the two poorest socio-economic groupings, as highlighted by the Scottish Index of Multiple Depravation. The aspirations of the individual participants are also considered in relation to their intended and actual aspirations and related to doxic, habituated, and emergent aspirations. The research in this dissertation is contextualised within the personal and professional experiences of the researcher and how their background was a catalyst for carrying out this research
Binary open clusters in the Milky Way: photometric and spectroscopic analysis of NGC 5617 and Trumpler 22
Using photometry and high resolution spectroscopy we investigate for the
first time the physical connection between the open clusters NGC 5617 and
Trumpler 22. Based on new CCD photometry we report their spatial proximity and
common age of ~70 Myr. Based on high resolution spectra collected using the
HERMES and UCLES spectrographs on the Anglo-Australian telescope, we present
radial velocities and abundances for Fe, Na, Mg, Al, Si, Ca and Ni. The
measured radial velocities are -38.63 +/-2.25 km/s for NGC 5617 and -38.46
+/-2.08 km/s for Trumpler 22. The mean metallicity of NGC 5617 was found to be
[Fe/H] =-0.18 +/-0.02 and for Trumpler 22 was found to be [Fe/H] = -0.17
+/-0.04. The two clusters share similar abundances across the other elements,
indicative of a common chemical enrichment history of these clusters. Together
with common motions and ages we confirm that NGC 5617 and Trumpler 22 are a
primordial binary cluster pair in the Milky Way.Comment: 7 pages, 3 figure, accepted by MNRA
Ultra-high-sensitivity two-dimensional bend sensor
A multicore fibre Fabry-Perot-based strain sensor interrogated with tandem interferometry for bend measurement is described. Curvature in two dimensions is obtained by measuring the difference in strain between three co-located low finesse Fabry-Perot interferometers formed in each core of the fibre by pairs of Bragg gratings. This sensor provides a responsivity enhancement of up to 30 times that of a previously reported fibre Bragg grating based sensor. Strain resolutions of 0.6 n epsilon/Hz(1/2) above 1 Hz are demonstrated, which corresponds to a curvature resolution of similar to 0.012 km(-1)/Hz(1/2)
Effectiveness and reach of a directed-population approach to improving dental health and reducing inequalities: a cross sectional study
Background
Childsmile School adopts a directed-population approach to target fluoride varnish applications to 20% of the primary one (P1) population in priority schools selected on the basis of the proportion of enrolled children considered to be at increased-risk of developing dental caries. The study sought to compare the effectiveness of four different methods for identifying individuals most in need when a directed-population approach is taken. <p></p>
Methods
The 2008 Basic National Dental Inspection Programme (BNDIP) cross-sectional P1 Scottish epidemiological survey dataset was used to model four methods and test three definitions of increased-risk. Effectiveness was determined by the positive predictive value (PPV) and explored in relation to 1-sensitivity and 1-specificity. <p></p>
Results
Complete data was available on 43470 children (87% of the survey). At the Scotland level, at least half (50%) of the children targeted were at increased-risk irrespective of the method used to target or the definition of increased-risk. There was no one method across all definitions of <i>increased-risk</i> that maximised PPV. Instead, PPV was highest when the targeting method complimented the definition of <i>increased-risk</i>. There was a higher percentage of children at <i>increased-risk</i> who were not targeted (1-sensitivity) when caries experience (rather than deprivation) was used to define <i>increased-risk</i>, irrespective of the method used for targeting. Over all three definitions of <i>increased-risk</i>, there was no one method that minimised (1-sensitivity) although this was lowest when the method and definition of <i>increased-risk</i> were complimentary. The false positive rate (1-specificity) for all methods and all definitions of <i>increased-risk</i> was consistently low (<20%), again being lowest when the method and definition of <i>increased-risk</i> were complimentary. <p></p>
Conclusion
Developing a method to reach all (or even the vast majority) of individuals at <i>increased-risk</i> defined by either caries experience or deprivation is difficult using a directed-population approach at a group level. There is a need for a wider debate between politicians and public health experts to decide how best to reach those most at need of intervention to improve health and reduce inequalities. <p></p>

Interaction of Supernova Ejecta with Nearby Protoplanetary Disks
The early Solar System contained short-lived radionuclides such as 60Fe (t1/2
= 1.5 Myr) whose most likely source was a nearby supernova. Previous models of
Solar System formation considered a supernova shock that triggered the collapse
of the Sun's nascent molecular cloud. We advocate an alternative hypothesis,
that the Solar System's protoplanetary disk had already formed when a very
close (< 1 pc) supernova injected radioactive material directly into the disk.
We conduct the first numerical simulations designed to answer two questions
related to this hypothesis: will the disk be destroyed by such a close
supernova; and will any of the ejecta be mixed into the disk? Our simulations
demonstrate that the disk does not absorb enough momentum from the shock to
escape the protostar to which it is bound. Only low amounts (< 1%) of mass loss
occur, due to stripping by Kelvin-Helmholtz instabilities across the top of the
disk, which also mix into the disk about 1% of the intercepted ejecta. These
low efficiencies of destruction and injectation are due to the fact that the
high disk pressures prevent the ejecta from penetrating far into the disk
before stalling. Injection of gas-phase ejecta is too inefficient to be
consistent with the abundances of radionuclides inferred from meteorites. On
the other hand, the radionuclides found in meteorites would have condensed into
dust grains in the supernova ejecta, and we argue that such grains will be
injected directly into the disk with nearly 100% efficiency. The meteoritic
abundances of the short-lived radionuclides such as 60Fe therefore are
consistent with injection of grains condensed from the ejecta of a nearby (< 1
pc) supernova, into an already-formed protoplanetary disk.Comment: 57 pages, 16 figure
