A Possible Beadmaker\u27s Kit from North America\u27s Lake Superior Copper District
Beads of copper are amongst the oldest and most widespread ornament forms known in North America. Native copper was an important material to prehistoric Americans, and certainly the most important metal. It was collected, transported and traded over wide areas from as early as seven thousand years before present, and its for ornaments persisted until it was gradually replaced by European metals over the many years of the contact period. A recently discovered cache of copper beads, bead preforms, awls, a crescent knife and scraps of raw copper at site 20KE20 in northern Michigan offers insight into the process of copper-bead production in fifth-century North America
Bridging the social and the biomedical: engaging the social and political sciences in HIV research
This supplement to the Journal of the International AIDS Society focuses on the engagement of the social and political sciences within HIV research and, in particular, maintaining a productive relationship between social and biomedical perspectives on HIV. It responds to a number of concerns raised primarily by social scientists, but also recognized as important by biomedical and public health researchers. These concerns include how best to understand the impact of medical technologies (such as HIV treatments, HIV testing, viral load testing, male circumcision, microbicides, and pre-and post-exposure prophylaxis) on sexual cultures, drug practices, relationships and social networks in different cultural, economic and political contexts. The supplement is also concerned with how we might examine the relationship between HIV prevention and treatment, understand the social and political mobilization required to tackle HIV, and sustain the range of disciplinary approaches needed to inform and guide responses to the global pandemic. The six articles included in the supplement demonstrate the value of fostering high quality social and political research to inform, guide and challenge our collaborative responses to HIV/AIDS

Language and Reading Progress of Young Deaf and Hard-of-Hearing Children.
We examined the language and reading progress of 336 young DHH children in kindergarten, first and second grades. Trained assessors tested children's language, reading, and spoken and fingerspelled phonological awareness in the fall and spring of the school year. Children were divided into groups based on their auditory access and classroom communication: a spoken-only group (n = 101), a sign-only group (n = 131), and a bimodal group (n = 104). Overall, children showed delays in language and reading compared to norms established for hearing children. For language, vocabulary standard scores were higher than for English syntax. Although delayed in language, children made expected gains based on hearing norms from kindergarten to second grade. Reading scores declined from kindergarten to second grade. Spoken-only and bimodal children had similar word reading and reading comprehension abilities and higher scores than sign-only children. Spoken-only children had better spoken phonological awareness and nonword reading skills than the other two groups. The sign-only and bimodal groups made similar and significant gains in ASL syntax and fingerspelling phonological awareness
Ion Charge States in Halo CMEs: What can we Learn about the Explosion?
We describe a new modeling approach to develop a more quantitative
understanding of the charge state distributions of the ions of various elements
detected in situ during halo Coronal Mass Ejection (CME) events by the Advanced
Composition Explorer (ACE) satellite. Using a model CME hydrodynamic evolution
based on observations of CMEs propagating in the plane of the sky and on
theoretical models, we integrate time dependent equations for the ionization
balance of various elements to compare with ACE data. We find that plasma in
the CME ``core'' typically requires further heating following filament
eruption, with thermal energy input similar to the kinetic energy input. This
extra heating is presumably the result of post eruptive reconnection. Plasma
corresponding to the CME ``cavity'' is usually not further ionized, since
whether heated or not, the low density gives freeze-in close the the Sun. The
current analysis is limited by ambiguities in the underlying model CME
evolution. Such methods are likely to reach their full potential when applied
to data to be acquired by STEREO when at optimum separation. CME evolution
observed with one spacecraft may be used to interpret CME charge states
detected by the other.Comment: 20 pages, accepted by Ap
A method for exploratory repeated-measures analysis applied to a breast-cancer screening study
When a model may be fitted separately to each individual statistical unit,
inspection of the point estimates may help the statistician to understand
between-individual variability and to identify possible relationships. However,
some information will be lost in such an approach because estimation
uncertainty is disregarded. We present a comparative method for exploratory
repeated-measures analysis to complement the point estimates that was motivated
by and is demonstrated by analysis of data from the CADET II breast-cancer
screening study. The approach helped to flag up some unusual reader behavior,
to assess differences in performance, and to identify potential random-effects
models for further analysis.Comment: Published in at http://dx.doi.org/10.1214/11-AOAS481 the Annals of

The Internationalization of a School Counseling Program at a Catholic University: Reflections Generated by a Community of Practice
This paper examines the internationalization experiences of four school counseling faculty members in a counseling program at a Catholic university. Counseling in general and counseling schools have become a global profession. As a result, it is imperative for training programs to develop graduates who are culturally competent across the globe. This reflective piece outlines the steps a Catholic university’s school counseling specialization has taken to internationalize its program and curriculum. Participants engaged in a community of practice to investigate thoroughly the current status of their program and curriculum. Findings highlight strengths and challenges associated with internationalization and the integration of Catholic Social Teaching into student international experiences. Strategies for others wishing to develop their own communities of practice to meet internationalization needs within Catholic institutions of higher education are presented and discussed
