The Process of Planning a Professional Conference

Maine Educational Center for the Deaf and Hard of Hearing is planning a spring conference for parent and professionals to bring together and raise awareness of parents and professionals in the Deaf and hard of hearing community. They are taking family-based feedback of needs in the field and are using a conference to support those in this community and address those needs to a broad range of professionals and families.https://digitalcommons.library.umaine.edu/ccids_posters/1053/thumbnail.jp

A Preliminary Study Of A Non-invasive Glucose Sensor Based On A Mercury Sensor

Diabetes mellitus is a potentially lethal disease that affects 7.6 percent of American people. In the US, it is recognized as the 6th leading cause of death. Failure to control blood glucose levels (BGL) in patients with either type of diabetes can lead to other serious complications as well, such as loss of limb, blindness and other health problems. Controlling and monitoring the BGL in post-op and intensive care patients in the hospital is also vital to their health. Currently the most reliable method of monitoring BGL is through an invasive procedure which monitors the amount of glucose in blood directly. A non-invasive glucose sensor would drastically improve the treatment of sensitive patients, and serve to improve the quality of diabetic patients\u27 lives. This glucose sensor is strongly based upon the mercury sensor developed by F.E. Hernandez and his colleagues. Glucose is used as a reducing agent to reduce mercury from Hg2+ to Hg0, which will form amalgams with the gold nanorods in solution. The change in aspect ratio of gold nanorods leads to a change in the UV-Visible spectrum of the solution. The blue shift seen was measured and correlated with the glucose concentration of the system. The system was then tested varying conditions such as pH, temperature, gold nanorod concentration, and mercury concentration. A preliminary study of the kinetics of the reaction was also done. The results showed a limit of detection of 1.58x10-13 and a linear dynamic range covering the concentrations of human tear glucose levels that are currently cited in the literature

A Behavioral Comparison of Four Inbred Strains of Mice

Isogenic, or inbred, mouse strains are currently the experimental subjects of choice in laboratory studies focused on genetics, pharmacology, and psychological issues. Understanding phenotypic differences in isogenic strains is important in order to interpret experimental results obtained from inbred mouse strains. Four commonly used inbred strains, C57BL/6NHsd (C57), DBA/2NHsd (DBA), 129S2/SvHsd (129), and Balb/cAnHsd (Balb/c), are investigated in this study using four different behavioral tasks that measure locomotor activity and cognitive behavior (Morris Water Maze (MWM), T-maze, and operant autoshaping procedures). In the locomotor activity task 129 mice showed significantly less horizontal ambulation than any other strain, while differences in rearing was seen between all strains, with C57 mice producing the most, and 129 showing the least rearing. Thigmotaxia was seen the most in the 129 strain, less so with the Balb/c and DBA strains, and the least in the C57 mice. In the MWM learning across strains was noted but there was no difference between the strains. In the T-maze the Balb/c strain showed the shortest latency to enter an arm, while the 129 strain showed the longest. As expected they also showed the lowest accuracy and the highest percent time-outs compared to all the other strains. In the autoshaping procedure little difference between the strains was observed. Balb/c mice trended graphically towards higher rates however there was no difference with regard to number of contingent responses or number per strain to reach a criterion of 10 or more contingent reinforcers. Finally, locomotor activity was measured again at the end of the study. The activity results were still similar, although the C57 strain showed a decrease in horizontal ambulation as compared to DBA and Balb/c strains; however, the 129 strain still showed the least activity. These results indicate that there are significant differences in locomotor behavior and cognitive processes in these strains that should be considered when interpreting results from studies using these inbred mouse strains

Effects of sex, parenting styles, and family factors on physical risk-taking behavior in children

The present study attempted to describe the effect of sex, parenting styles, and family factors on physical risk-taking behavior on children by analyzing self-report data collected from 93 mothers in the Midwest region of the United States. Previous research has shown that unintentional injury - closely related to physical risk-taking - is one of the leading causes of death, hospitalization, and permanent impairment in children and adolescents (Morrongiello, Zdxieborski, & Normand, 2010; Galligan, & Kuebli, 2011; Wells, Morrongiello, & Kane, 2012; Ablewhite, Kendrick, Watson, & Shaw, 2016). Results of this study indicated significant relationships between levels of authoritarian parenting styles and injury caused by physical risk-taking behavior for female children. Other analysis found indirect relationships between various parenting, child behavior, and family factors that can be used to explain physical risk-taking behavior in children

EFFECTS OF HUMAN-ORANGUTAN COOPERATION AT THE INDIANAPOLIS ZOO

poster abstractThe Indianapolis Zoo is in the process of developing a new orangutan ex-hibit. The exhibit aims to help zoo guests develop an appreciation for the cognitive abilities of orangutans as well as understand how those abilities have helped the animals survive in the forest. The goals of the experience are to ultimately affect zoo guests’ attitudes and beliefs about orangutans and the importance of forest conservation. To that end, the zoo will be im-plementing interactive devices that allow orangutans living in the exhibit and zoo guests to work cooperatively on a series of discrete, individualized tasks. In the summer of 2011, IUPUI Museum Studies graduate students con-ducted visitor studies research and evaluation on a Chutes Interactive proto-type. The prototype invited research participants to cooperate with an orangutan by taking turns with the animal to rotate a series of chambers. With each rotation, a treat moved from the top of the device to a bottom chute, where the ape could retrieve it. Researchers used questionnaires, meaning mapping, and direct observa-tion methods to measure: 1) the extent of guest interaction at the device, 2) gains in general content knowledge/conceptual that occurred after the expe-rience, and 3) prototype functionality with regard to the exhibit goals and mechanics. Evaluation of the experience revealed that the cooperative expe-rience stimulated little long-term change in participant attitudes and behav-iors toward orangutans; that participants showed cognitive gain after the prototype activity, but not in knowledge areas identified as the core goals of the experience; and that design elements should be reconsidered to ensure the device would function properly more often

An Atomic Force Microscopy Nanoindentation Study of Size Effects in Face-Centered Cubic Metal and Bimetallic Nanowires

The enhancement of strength of nanoscale materials such as face-centered cubic metal nanowires is well known and arises largely from processes mediated by high energy surface atoms. This leads to strong size effects in nanoscale plasticity; ,smaller is stronger. Yet, other factors, such as crystalline defects also contribute greatly to the mechanical properties. In particular, twin boundaries, which are pervasive and energetically favorable defects in face-centered cubic metal nanowires, have been shown to greatly enhance the strength, furthermore this increase in strength has been shown to be directly influenced by the twin density. However, attempts to control the introduction of beneficial defects remains challenging. Additionally, even minor local variations in the crystalline structure or size of metal nanowires may have drastic effects on the yielding of metal nanowires, which are difficult to measure through tensile and bending tests. In this study, atomic force microscopy based nanoindentation techniques are used to measure the local plasticity of Ni-Au bimetallic as well as Cu and Ag metallic nanowires. In the first part of the thesis the hardness of bimetallic nanowires synthesized through template-assisted electrodeposition is measured and found to show significant size-effects. It was found that the nanoindentation hardness was governed by materials properties, the observed indentation size effects were dependent on geometrical factors. The second part of this thesis presents a methodology to control the crystal structure of Ag and Cu nanowires through direct electrodeposition techniques, which were tested directly as grown on the substrate to limit effects of pre-straining. Ag nanowires showed marked size-effects as well as two distinct modes of deformation which we attribute to the defects that arise during crystalline growth. We also show control of the surface microstructure in Cu nanowires which leads to strengths that are more than doubled compared to single crystalline Cu nanowires. Finally, we present support from classic crystal growth theory to justify that the observed plasticity in Ag and Cu nanowires is largely dependent on defects that are nucleated through changes in the growth environment

Reduction of Anomie through the Use of Say It Straight Training

This study evaluated the Say It Straight (SIS) Training Program for its ability to improve straightforward communication, increase self-esteem, increase an individual's overall perception of group and family belonging or cohesiveness within a residential treatment setting and decrease an individual's perceived level of anomie. Effectiveness of SIS training was evaluated with paired sample t-tests (2-tailed) on six objective questionnaires given before and after training. Participation in the study was voluntary. Of the 39 patients in residence, 26 participated in SIS training, (23 attended over 80% of the sessions and 3 attended over 50%). Three were excluded from the study due to developmental or dementia-related diagnoses, 3 chose not to participate, 5 were discharged routinely prior to completion and were not post-tested; and 2 were discharged against medical advice during the training. It is interesting to notice that on the average there are about 5 discharges against medical advice per month at the facility, but during the five weeks of SIS there were only 2. Self-reports of empowering behaviors, quality of family and group life and self-esteem showed highly significant increases following SIS. Self-reports of disempowering behaviors (placating, passive-aggressive, blaming, irrelevant, intellectualizing) showed highly significant decreases following SIS and anomie showed a significant decrease. All p values are results from 2-tailed t-tests for paired observations. Subjective reports regarding training effectiveness were also very positive. Recommendations include: 1) follow-up and compare SIS trained Sante alumni and non-SIS trained Sante alumni for recidivism rate and participation in recovery oriented group activities; 2) develop a tool for measuring anomie specifically related to treatment settings as a construct versus a single variable, and 3) develop a tool for measuring group cohesiveness specifically related to treatment settings as a construct versus a single variable

Adaptive calibration of risk-taking: The role of parenting styles, emotion regulation and stress reactivity

The present study was designed to understand whether experienced parenting style in childhood and emotion regulation strategies can predict the relationship between stress reactivity and risk-taking behaviors. Based on the Adaptive Calibration Model it was predicted that the relationship between cortisol and risk-taking behavior would be influenced by early life experiences with parents and emotion regulation strategies. To test the hypotheses, 156 college age students were recruited to participate in an experimental study in which half of the participants experienced a stressful social situation before engaging in a computerized risk-taking task. The results of the present study suggested that cortisol reactivity marginally increased risk-taking propensity. However, the present study did not find evidence that differences in risk-taking were influenced by interactions between parenting style and emotion regulation with cortisol reactivity. Results of the present study have implications in future research design of studies using computerized measures of risk-taking, and areas of future research in the field based on trends in the current data
