Involve Ohio State University students in service activities related to food, gardening, and health in the Columbus community.OSU PARTNERS: College of Social Work; College of Food, Agricultural, and Environmental SciencesCOMMUNITY PARTNERS: Waterman Farm; Master Gardener Program; Ohio State University Extension Program; Hill Phoenix; Sites still in process, but working with Columbus City Schools, Columbus Free ClinicPRIMARY CONTACT: Margaret Griffin ([email protected])This program aims to increase produce accessibility through campus community connection. A community garden will be created on Waterman Farm that will be managed by students from Ohio State. The produce grown at that plot will be placed in five different sites that are located in food deserts. The produce will be delivered bi-weekly to twelve families per site

Deterioration mechanisms of historic cement renders and concrete
Since the introduction of Portland cement in the early nineteenth century the number
of buildings constructed from concrete or using cement mortars and renders has
grown exponentially, and cement is one of the most common building materials in
use today. Consequently a significant proportion of the built heritage contains
cementitious materials. The relative youth of these buildings means that less research
has been undertaken to understand how and why they deteriorate than for traditional
buildings, and that the development of appropriate conservation methods and
techniques is less advanced.
The primary aim of this research was to understand the causes and
mechanisms of some of the types of deterioration commonly found in historic
concrete and cement buildings and structures, with reference to the Second World
War reinforced concrete and cement-rendered buildings at East Fortune airfield in
East Lothian, Scotland. Additional aims were to investigate the efficacy of the
building repairs and maintenance regimes undertaken to date, and to make
recommendations for the future conservation of the buildings.
East Fortune airfield contains a number of cement-rendered brick masonry
buildings and a reinforced concrete air raid shelter. The initial visual survey
identified several types of deterioration, from which the blistering and flaking of the
render; the cracking and delamination of the render; and the spalling of the concrete
in the air raid shelter were selected for further research. The research included time
lapse photography, non-destructive testing, environmental monitoring and the
physical, chemical and petrographic characterisation of the building materials.
Hypotheses regarding the causes of deterioration were tested in the laboratory, for
example with linear variable displacement transducer measurements, and modelled
using crack propagation theories and models for water transport through porous
media.
It is demonstrated that the blistering and flaking of the render is caused by
shale aggregate particles, which undergo sufficient expansion during freeze-thaw
cycles to crack the surrounding render. This phenomenon is termed ‘pop-outs’ in the
concrete literature. The more catastrophic cracking and delamination of the renders is
also due to freeze-thaw cycling, which is shown to cause significant damage
provided the moisture content of the render is above a certain threshold level. This
type of deterioration has occurred at an accelerated rate for some of the modern
render repairs, due to an inadequate understanding of the properties of the original
and repair materials. In particular, the properties of the bricks are critical to the
performance of the cement renders, and it is found that the sorptivity of historic
bricks may vary considerably depending upon the orientation of the brick. Finally,
the diagnosis for the air raid shelter is that the corrosion of the steel reinforcements is
caused by high levels of chlorides present within the raw materials used to make the
pre-cast concrete sections.
The results of the investigations are used to suggest building conservation
solutions for this particular site. Furthermore, since the deterioration mechanisms
investigated are common for historic cement and concrete, the findings are relevant
to many other sites. The over-arching methodology used to investigate the
deterioration at the site and the methodologies developed to test particular
hypotheses are also applicable for other investigations of historic building materials.
There is much about this research that is innovative and new. The work on
render cracking compares the results of dilation tests on cementitious and ceramic
materials, which has not been done previously, and the pop-outs diagnosed in the
work on render flaking have rarely, if ever, been reported for cement renders. The
modelling work undertaken to quantify the stresses produced by the pop-outs and to
explain the inclined crack formation patterns is entirely original. The use of
petrography to diagnose causes of render failure is described in the literature, but this
is one of very few case studies to be written up, and the work on the air raid shelter
constitutes the only formal investigation of this type of Stanton shelter
Variability of Diagnostic Symptoms of ASD in Individuals with Fragile X Syndrome
Purpose or Research Questions In 2013, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) provided a new framework of criteria for diagnosing autism spectrum disorder (ASD), differing from the previous edition, the DSM-IV, in both structure of criteria and number of criteria needed for a diagnosis. This study aims to further understand the relationship that exists between specific ASD symptoms observed and the presence of an ASD diagnosis in this population. Background A recent analysis of this data (DeRamus et al., 2016) demonstrated that more individuals with FXS met criteria for ASD on the ADOS-2 when mapped to the diagnostic framework of DSM-IV than that of DSM-V. This current exploratory study is a sub-analysis of data obtained by the Decisional Capacity in fragile X syndrome study at the UNC-CH Carolina Institute for Developmental Disabilities and Research Triangle Institute and examines symptoms of autism through the gold-standard behavioral assessment for ASD, the ADOS-2. Methods/Proposed Methods One method for exploring the differences between diagnoses resulting from DSM-IV vs DSM-V criteria is to look at a relaxed version of DSM-V criteria, reducing the number of qualifying symptoms by one in both social communication and interaction (SCI) and repetitive and restricted behaviors and interests (RRBI) criteria. The symptoms of ASD in 143 individuals with FXS (72 male and 71 female) from the ADOS-2 were examined with regards to the criteria of SCI and RRBI. In addition, frequencies of meeting criteria for ASD based on a relaxed diagnostic criteria of the DSM-V standards were examined. Results/Anticipated Results 75% of males and 21% of females met SCI criteria under DSM-V criteria, while 87% of males and 64% of females met SCI criteria under relaxed DSM-V criteria. 59% of males and 21% of females met RRBI criteria under DSM-V; however, 89% of males and 64% of females met RRBI under relaxed DSM-V criteria. Overall, 56% of males and 16% of females met criteria for ASD under DSM-V, and 79% of males and 50% of females met criteria for ASD under relaxed DSM-V criteria. When only the SCI criterion was relaxed by one qualifying symptom, 59% of males and 19% of females met criteria for ASD. When only the RRBI criterion was relaxed by one qualifying symptom, 72% of males and 37% of females met criteria for ASD. Discussion There is a larger increase for both males (16% higher) and females (21% higher) meeting criteria when the RRBI criterion is relaxed by one qualifying symptom as compared to when the SCI criterion is relaxed by one qualifying symptom (3% higher for male and females). Further analysis will be done to determine the significance of these differences and to look into the sub-criteria within the SCI and RRBI domains. Examination of the ASD symptomatic profile of individuals with FXS is important to the understanding of diagnostic trends and the focus of further treatment due to funding constraints on services covered by insurance
Informing Innovations Through Deeper Insight on Strategic Priorities and Expansive Ideas
Recent national Extension initiatives and reports provide insight into innovation trends and issues. In response to questions from participants in eXtension Impact Collaborative events, we adapted two business frameworks to provide deeper insight about innovation. The adapted frameworks are helpful for identifying strategic areas of focus for innovation and prompting expanded thinking about potential types of innovation
