Examining 4-H Robotics in the Learning of Science, Engineering and Technology Topics and the Related Student Attitudes

Youths’ natural fascination and identification with robots make them an ideal teaching and learning platform. Robots would seem to be excellent hands-on tools to teach science, engineering and technology (SET) concepts. However, while research supports their use to increase interest and motivation, the effectiveness of robots to directly teach science, engineering, and technology concepts is less clear. The purpose of this study was to measure the effectiveness of a 4-H robotics program to support the learning of specific SET concepts and to examine related student attitudes towards science. This study compared the pretest and posttest scores on an assessment of basic SET concepts and attitudes of youth who participated in the 4-H robotics intervention with the scores of youth in a control group. Analysis of covariance (ANCOVA) results revealed that youth in the robotics intervention scored better on a SET concepts posttest. Student attitudes toward science were also investigated. The results suggested that educational robotics can engage youth in activities that support their learning of SET topics, but that it may have more limited impact on general student attitudes towards science, as measured by the study\u27s attitudinal instrument

If You Can, You Can

VCU distinguishes itself as being one of Virginia’s most diverse institutions of higher education. This project seeks to support and extend this wonderful attribute by encouraging a climate of equity and inclusiveness. If You Can, You Can creates a common platform and language in support of the university’s mission to address disparities concerning equality and inclusiveness, and provides a model that is useful in promoting all dimensions of diversity. In addition to developing this overarching model, Team Real Connections worked with the VCU Athletics department to implement a prototype program called “If you can play, you can play,” which promotes inclusivity for those in the LGBTQ community within athletics. That initiative is comprised of the following components: ● the production of a marketing video to introduce and promote the campaign ● the submission of the video to the national “You Can Play” project (http://youcanplayproject.org/) ● a survey assessing how VCU athletes perceive the current climate in athletics ● training sessions with athletic coaches and staff to promote awareness and advocacy for the LGBTQ community ● dissemination of posters, postcards, and wristbands to promote the campaign and publicize events ● programs in October (LGBTQ History Month) with speakers Pat Griffin and Hudson Taylor to bring further awareness to the importance of inclusivity ● promotion of the campaign and events at various athletic events The success of the prototype campaign demonstrates that If You Can, You Can has the potential to serve as a comprehensive platform for units around VCU who wish to promote inclusivity and equity along other dimensions of diversity. Ultimately, the team envisions a university-wide initiative that unites VCU in achieving its goal of becoming a premier urban research university where everyone is welcomed, supported, and valued

Hormone therapy in relation to survival from large bowel cancer.

Epidemiologic studies of hormone therapy (HT) and colorectal cancer incidence consistently show an inverse association; however, few studies have considered prediagnostic use of HT on mortality among colorectal cancer patients. We evaluated the relationship of HT and survival among a population-based cohort of women with large bowel cancer. Cases (n = 1,297) were newly diagnosed with invasive cancer of the colon or rectum, aged 40-74 years at diagnosis, who were identified by Wisconsin's statewide registry (1988-1991; 1997-2001) for two case-control studies. Information on HT use and other colorectal cancer risk factors was collected by standardized interview. There were 507 deaths (274 of these attributable to colorectal cancer) over 8.4 years of follow-up through December 2005. Hormone use was not associated with colorectal cancer mortality (adjusted hazard rate ratio = 1.09, confidence interval = 0.81-1.47). Colorectal cancer specific mortality was not associated with HT when considered separately by preparation type. Stage did not modify this relationship. Long-term HT was weakly positively associated with increased mortality after diagnosis of proximal colon, but not distal colon cancer. Because we detected no differences in survival among users of HT compared to non-users, the results suggest that HT use may affect only the incidence of some colorectal tumors

Hormone therapy and ovarian cancer: incidence and survival.

OBJECTIVE: We conducted a population-based case-control study to investigate the association between hormone therapy (HT) and ovarian cancer incidence, and followed all these cancer cases to determine the association of HT use with ovarian cancer mortality. METHODS: Seven hundred fifty-one incident cases of invasive epithelial ovarian cancer aged 40-79 years were diagnosed in Massachusetts and Wisconsin between 1993-1995 and 1998-2001 and matched to similarly aged controls (n = 5,808). Study subjects were interviewed by telephone, which ascertained information on HT use and specific preparation, estrogen alone (E-alone) or estrogen plus progestin (EP). Ovarian cancer cases were followed-up for mortality through December 2005. Multivariate logistic regression was used to estimate odds ratios and 95% confidence intervals (CI) for ovarian cancer incidence, and Cox proportional hazards modeling was used to estimate hazard ratios and corresponding confidence intervals for ovarian cancer mortality. RESULTS: Ever use of HT was significantly associated with an increased risk of ovarian cancer (odds ratio 1.57, 95% CI 1.31-1.87). The excess risk was confined to women who used E-alone preparations (OR 2.33, 95% CI 1.85-2.95). No significant associations were detected between pre-diagnosis HT use and ovarian cancer survival. CONCLUSIONS: Hormone therapy increases risk of ovarian cancer among E-alone users, but there is no substantial impact on survival after diagnosis

A validated measure of adherence to antibiotic prophylaxis in children with sickle cell disease

BACKGROUND: Antibiotic prophylaxis is a mainstay in sickle cell disease management. However, adherence is estimated at only 66%. This study aimed to develop and validate a Sickle Cell Antibiotic Adherence Level Evaluation (SCAALE) to promote systematic and detailed adherence evaluation. METHODS: A 28-item questionnaire was created, covering seven adherence areas. General Adherence Ratings from the parent and one health care provider and medication possession ratios were obtained as validation measures. RESULTS: Internal consistency was very good to excellent for the total SCAALE (α=0.89) and four of the seven subscales. Correlations between SCAALE scores and validation measures were strong for the total SCAALE and five of the seven subscales. CONCLUSION: The SCAALE provides a detailed, quantitative, multidimensional, and global measurement of adherence and can promote clinical care and research

Pre-Diagnosis Oophorectomy, Estrogen Therapy and Mortality in a Cohort of Women Diagnosed with Breast Cancer

Introduction: Pre-diagnosis oophorectomy and estrogen therapy could impact mortality due to breast cancer and cardiovascular disease (CVD) among breast cancer survivors. Elective bilateral oophorectomy at the time of hysterectomy for benign conditions is not uncommon among US women. Methods: We examined the association between pre-diagnosis total abdominal hysterectomy with bilateral salpingo-oophorectomy (TAHBSO) and both overall and cause-specific mortality in the Collaborative Breast Cancer Studies cohort. Medical history and prior estrogen use were collected during standardized telephone interviews. Vital status, including date and cause of death, was obtained by linkage with the National Death Index. Multivariate hazard ratios (HR) and 95% confidence intervals (CI) for cause-specific mortality were calculated using Cox proportional hazards regression. Results: Seventeen percent (N = 1,778) of breast cancer survivors (mean age at diagnosis = 63.5) reported pre-diagnosis TAHBSO. During follow-up (mean = 9.5 years), 2,856 deaths occurred, including 1,060 breast cancer deaths and 459 CVD deaths. Breast cancer deaths occurred a median of 5.1 years after diagnosis; CVD deaths occurred further from diagnosis (median = 9.7 years). Women who reported pre-diagnosis TAHBSO had a 16% decrease in all-cause mortality (HR = 0.84; 95% CI: 0.76, 0.92) compared to those with an intact uterus and ovaries. This overall decrease reflected a 27% lower breast cancer mortality among women who never used postmenopausal hormones (HR = 0.73; CI: 0.55, 0.96) and 43% lower CVD risk among women who reported using estrogen (HR = 0.57; CI: 0.39, 0.83) after TAHBSO. Conclusions: Information on prior TAHBSO and estrogen use can inform risk of death from both breast cancer and cardiovascular disease among breast cancer survivors
