The SOM High Rise Studio was a collaboration between 3rd year Architecture students and primarily 4th year Architectural Engineering students. The studio consisted of 20 weeks, with consistent check points marked by SOM partner reviews. The overall aim of the collaboratory nature of the studio was to expose each discipline to the decision-making process of the other to better facilitate understanding of the overall system and narrative of the high-rise tower.
Each quarter had a distinct goal that was the focus of submittals and reviews. Winter Quarter was primarily focused on the form finding aspect of our design through means of precedent studies, physical modeling, and simplified studies on tall building behavior analyses. At the end of Winter Quarter, teams had the general structural system for their tower set and had begun looking at massing for wind mitigation and programming.
Spring Quarter was more focused on specific components of the tower, though the exact components differed it can be generalized as performative envelope studies, structural connections and compatibility, tower behavior, and simplified member sizing for idealized wind and seismic conditions. At the end of Spring quarter, teams were expected to have a functioning performative envelope, both architecturally and structurally, details showing working connections, and a functioning computer model

'They've invited me into their world': a focus group with clinicians delivering a behaviour change intervention in a UK contraceptive service.
Although teenage conceptions rates in the United Kingdom (UK) have seen a downward trend recently, it remains imperative that contraceptive services for young people continue to improve. To ensure that evidence-based interventions are sustained in clinical practice, it is useful to assess the experiences of those delivering them. This study explores the experiences of sexual health clinicians who were trained to deliver a one-to-one behaviour change intervention aiming to improve contraceptive use in young women. The intervention was set in a UK NHS contraceptive and sexual health service and involved clinicians' facilitating (within one-to-one consultations) the formation of implementation intentions (or 'if-then' plans) that specified when, where and how young women would use contraception. A focus group was conducted with seven clinicians who had delivered the intervention. A thematic analysis of the focus group revealed three overall themes: (1) How the intervention worked in practice; (2) barriers and benefits to delivering the intervention; and (3) positive changes to individual consultation style and wider 'best practice' within the clinic. Our findings show that, with support, clinical staff would be in favour of incorporating if-then planning as a strategy to help promote contraceptive adherence in young women
The legacy of social anxiety-linked negative expectancy: A pathway from pre-event negative expectancies to post-event negative thinking
This is the final version. Available from Elsevier via the DOI in this record.âŻRepository:
Materials, data, and analysis outputs described in this manuscript are
available at https://osf.io/sghuj/Background and objectives: Following engagement in a social event people with heightened vulnerability to social
anxiety report elevated levels of negative thinking about the event, and this post-event negative thinking is
implicated in the maintenance of social anxiety vulnerability. It has also been established that heightened social
anxiety vulnerability is associated with disproportionately negative expectations of upcoming social events.
However, contribution of social anxiety-linked pre-event negative expectancy to post-event negative thinking has
not been directly investigated. The objective of the present study was to test the hypothesis that the relationship
between social anxiety vulnerability and post-event negative thinking is mediated by pre-event negative expectancies that drive increased state anxiety at the time of encountering the event.
Methods: One-hundred and ten participants who varied in social anxiety vulnerability completed a simulated job
interview. Participants reported negativity of expectancies before the event, state anxiety experienced at the time
of encountering the event, and post-event negative thinking across the seven days following the event.
Results: Analyses revealed elevated social anxiety predicted increased negative post-event thinking. The association between social anxiety and post-event negative thinking was fully mediated by a mediation pathway
involving pre-event negative expectancies and state anxiety at the time of encountering the interview event.
Limitations: The study used a laboratory-based social experience, and conclusions could usefully be tested in the
context of natural social events.
Conclusions: The findings suggest that social anxiety-linked variation in pre-event negative expectancy may
contribute to post-event negative thinking following a social event via its impact on state anxiety.Australian Research Counci
Relativistic MHD and black hole excision: Formulation and initial tests
A new algorithm for solving the general relativistic MHD equations is
described in this paper. We design our scheme to incorporate black hole
excision with smooth boundaries, and to simplify solving the combined Einstein
and MHD equations with AMR. The fluid equations are solved using a finite
difference Convex ENO method. Excision is implemented using overlapping grids.
Elliptic and hyperbolic divergence cleaning techniques allow for maximum
flexibility in choosing coordinate systems, and we compare both methods for a
standard problem. Numerical results of standard test problems are presented in
two-dimensional flat space using excision, overlapping grids, and elliptic and
hyperbolic divergence cleaning.Comment: 22 pages, 8 figure
The beta Pictoris association: Catalog of photometric rotational periods of low-mass members and candidate members
We intended to compile the most complete catalog of bona fide members and
candidate members of the beta Pictoris association, and to measure their
rotation periods and basic properties from our own observations, public
archives, and exploring the literature. We carried out a multi-observatories
campaign to get our own photometric time series and collected all archived
public photometric data time series for the stars in our catalog. Each time
series was analyzed with the Lomb-Scargle and CLEAN periodograms to search for
the stellar rotation periods. We complemented the measured rotational
properties with detailed information on multiplicity, membership, and projected
rotational velocity available in the literature and discussed star by star. We
measured the rotation periods of 112 out of 117 among bona fide members and
candidate members of the beta Pictoris association and, whenever possible, we
also measured the luminosity, radius, and inclination of the stellar rotation
axis. This represents to date the largest catalog of rotation periods of any
young loose stellar association. We provided an extensive catalog of rotation
periods together with other relevant basic properties useful to explore a
number of open issues, such as the causes of spread of rotation periods among
coeval stars, evolution of angular momentum, and lithium-rotation connection.Comment: Forthcoming article, Received: 20 June 2016 / Accepted: 09 September

Trouble at the top: The construction of a tenant identity in the governance of social housing organizations
The project of citizen governance has transformed the social housing sector in England where 20,000 tenants now sit as directors on the boards of housing associations, but the entrance of social housing tenants to the boardroom has aroused opposition from the chief executives of housing companies and triggered regulatory intervention from government inspectors. This paper investigates the cause of these tensions through a theoretical framework drawn from the work of feminist philosopher Judith Butler. It interprets housing governance as an identificatory project with the power to constitute tenant directors as regulated subjects, and presents evidence to suggest that this project of identity fails to completely enclose its subject, allowing tenant directors to engage in âidentity workâ that threatens the supposed unity of the board. The paper charts the development of antagonism and political tension in the board rooms of housing companies to present an innovative account of the construction and contestation of identities in housing governance
