An Exploration of the Intercultural Competence and the Cross-Cultural Experiences of Educational Psychologists in the United Kingdom
The United Kingdom (UK) is becoming increasingly diverse (Office for National Statistics, 2013). Educational psychologists in the UK will need to feel competent in providing services to an increasingly multicultural population. This research study used a mixed method, two-phase, sequential, explanatory study design to explore the self-perceived intercultural competence of UK educational psychologists and trainee educational psychologists (EP/Ts). The study also explored EP/Ts experiences of working with culturally diverse populations. The first phase of this research study used an online adapted version of the MCCTS-R (Holcomb-McCoy & Myers, 1999; Munoz, 2009), and the second phase built upon the first phase with follow-up semi-structured interviews, analysed using Braun & Clarke's (2006) thematic analysis.
The results of this research study present a breadth and depth of information. EP/Ts generally perceived themselves to be competent to work cross-culturally with particular areas of competence including knowledge of assessment bias, poverty effects, and positive attitudes towards diverse cultures. EP/Ts also reported areas of lower competence including theories of racial/ethnic identity development, limited experiences of community work and limited knowledge of community resources. However, EP/Ts perceptions about development needs depended upon their awareness. The process of participating in the study raised awareness of gaps in knowledge and limitations in practice. The study concludes with a discussion of implications for the practice of EP/Ts
Generically Stable Measures and Distal Regularity in Continuous Logic
We develop a theory of generically stable and smooth Keisler measures in NIP
metric theories, generalizing the case of classical logic. Using smooth
extensions, we verify that fundamental properties of (Borel)-definable measures
and the Morley product hold in the NIP metric setting. With these results, we
prove that as in discrete logic, generic stability can be defined equivalently
through definability properties, statistical properties, or behavior under the
Morley product. We also examine weakly orthogonal Keisler measures,
characterizing weak orthogonality in terms of various analytic regularity
properties.
We then examine Keisler measures in distal metric theories, proving that as
in discrete logic, distality is characterized by all generically stable
measures being smooth, or by all pairs of generically stable measures being
weakly orthogonal. We then use this, together with our results on weak
orthogonality and a cutting lemma, to find analytic versions of distal
regularity and the strong Erd\H{o}s-Hajnal property
A randomized trial in a massive online open course shows people don't know what a statistically significant relationship looks like, but they can learn
Scatterplots are the most common way for statisticians, scientists, and the
public to visually detect relationships between measured variables. At the same
time, and despite widely publicized controversy, P-values remain the most
commonly used measure to statistically justify relationships identified between
variables. Here we measure the ability to detect statistically significant
relationships from scatterplots in a randomized trial of 2,039 students in a
statistics massive open online course (MOOC). Each subject was shown a random
set of scatterplots and asked to visually determine if the underlying
relationships were statistically significant at the P < 0.05 level. Subjects
correctly classified only 47.4% (95% CI: 45.1%-49.7%) of statistically
significant relationships, and 74.6% (95% CI: 72.5%-76.6%) of non-significant
relationships. Adding visual aids such as a best fit line or scatterplot smooth
increased the probability a relationship was called significant, regardless of
whether the relationship was actually significant. Classification of
statistically significant relationships improved on repeat attempts of the
survey, although classification of non-significant relationships did not. Our
results suggest: (1) that evidence-based data analysis can be used to identify
weaknesses in theoretical procedures in the hands of average users, (2) data
analysts can be trained to improve detection of statistically significant
results with practice, but (3) data analysts have incorrect intuition about
what statistically significant relationships look like, particularly for small
effects. We have built a web tool for people to compare scatterplots with their
corresponding p-values which is available here:

Environmental Changes and the Dynamics of Musical Identity
Musical tastes reflect our unique values and experiences, our relationships
with others, and the places where we live. But as each of these things changes,
do our tastes also change to reflect the present, or remain fixed, reflecting
our past? Here, we investigate how where a person lives shapes their musical
preferences, using geographic relocation to construct quasi-natural experiments
that measure short- and long-term effects. Analyzing comprehensive data on over
16 million users on Spotify, we show that relocation within the United States
has only a small impact on individuals' tastes, which remain more similar to
those of their past environments. We then show that the age gap between a
person and the music they consume indicates that adolescence, and likely their
environment during these years, shapes their lifelong musical tastes. Our
results demonstrate the robustness of individuals' musical identity, and shed
new light on the development of preferences.Comment: Accepted to be published at ICWSM'1
The ACS Survey of Galactic Globular Clusters. X. New Determinations of Centers for 65 Clusters
We present new measurements of the centers for 65 Milky Way globular
clusters. Centers were determined by fitting ellipses to the density
distribution within the inner 2\arcmin of the cluster center, and averaging
the centers of these ellipses. The symmetry of clusters was also analyzed by
comparing cumulative radial distributions on opposite sides of the cluster
across a grid of trial centers. All of the determinations were done with
stellar positions derived from a combination of two single-orbit ACS images of
the core of the cluster in and . We find that the
ellipse-fitting method provides remarkable accuracy over a wide range of core
sizes and density distributions, while the symmetry method is difficult to use
on clusters with very large cores, or low density. The symmetry method requires
a larger field, or a very sharply peaked density distribution.Comment: 17 pages, 8 figures, Accepted for publication in AJ, supplementary
