Recent discoveries about the role of microorganisms in the establishment of the geological conditions in the planet have lead to the development of courses in Geomicrobiology. Unfortunately, most courses are designed for students with a strong Geology background, which is a limitation for universities that lack such courses. To overcome this limitation at our university, we have designed a special topics course entitled Introductory Geomicrobiology that was offered for the first time to undergraduate students from the Biology, Marine Biology and Microbiology Programs. To attract non-geology majors the course included topics such as description of Early Earth ecosystems, search for geo-biological signatures and current approaches in the search for extra-terrestrial life forms. An active learning environment was fostered throughout the course through different activities including oral reports of research papers in the subject, followed by Gallery Runs and class discussions. Our assessment strategies, both formative and summative, revealed that such presentations were an effective way to introduce students to eight main concepts of Geomicrobiology. Student performance was stronger in group discussions than individually, with Gallery Runs as the preferred class discussion technique. Overall, our assessment system proved that the design of the course was effective in teaching Geomicrobiology to nongeology majors.

This paper describes a highly successful peer tutoring program that has resulted in an improvement in the passing rates of mathematics placement exams from 16% to 42%, on average. Statistical analyses were conducted using a Chi-Squared (?[superscript 2]) test for independence and the results were statistically significant (p-value much less than 0.05). These encouraging results suggest that this type of initiative should be institutionalized at the end of the grant period that funds it. The paper describes the structure of the program, the conditions of the university in which it is being implemented, the details of the statistical analyses, and its impact in engineering education. This model may easily be replicated in academic institutions with similar conditions.

This paper reports on research into developing research skills in human resources management of apprentices through experiential learning. The target groups were undergraduate business students registered in the Introduction to Personnel and Industrial Relations course. The research identified the appreciation level of importance and satisfaction from apprentices since the acquisition and development of research skills for human resources management discipline. Data analysis indicates, firstly the importance of acquisition and development research skills in human resources management are congruent with the needs required for the contemporary organization and career objectives of the apprentices and future human resources professionals. The results obtained have positive implications on apprentices from research skills statements such as organizational goal's achievement, job analysis, human resources audit, strategic planning, statistical analysis, and evidence-based in human resources management to diminish the skills gap through the curriculum development in human resources management.

The PROTECT research Center funded by the NIH's National Institute of Environmental Health Sciences (NIEHS) Superfund Research Program was launched in 2010 to explore the impact of exposure to pollutants on the high rate of premature births in Puerto Rico. In September 2017, Hurricanes Irma and María devastated the archipelago, which caused: collapse of the electrical system, collapse of the communication system, limited access to clean water, food, gas, and health services, destruction of public (e.g., hospitals) and private property (e.g., houses) and more than 4500 deaths. Pregnant and postpartum individuals are especially vulnerable to natural disasters. They face difficulty obtaining adequate pre- and post-natal care, are exposed to increased risk of miscarriage, premature delivery, and giving birth to low birth weight babies during and after disasters and are also more likely to suffer physical and mental health problems compared to the general population during and after disasters. A face-to-face questionnaire was administered to PROTECT participants who were pregnant during hurricanes Irma or Maria or who became pregnant shortly after in order to identify hurricane-related sources of stress and other adverse effects. This paper is based on the answers to the open-ended question at the end of the questionnaire where participants were asked to share their experiences during and after the hurricanes. Among the 375 participants who completed the survey, 76 answers to the open-ended question were considered due to data saturation. The answers to the open-ended question were transcribed into a document in order to facilitate the coding process. The transcribed text was analyzed first to identify emerging categories and then coded to identify common themes as well as divergence among participants. The following themes were identified: pregnancy and birth challenges, lack of access to basic services, housing conditions, stressful working conditions, concerns about health, concerns about their children, and positive or protective aspects. The results indicate how the disruption in access to basic services has a unique impact on the physical and mental health of pregnant and post-partum women in an emergency situation. These findings point to the potential benefit of developing specific protocols designed for emergency preparedness aimed at this population, which can inform healthcare providers and community organizations in case of future events.

BACKGROUND: The Sister Study was designed to address gaps in the study of environment and breast cancer by taking advantage of more frequent breast cancer diagnoses among women with a sister history of breast cancer and the presumed enrichment of shared environmental and genetic exposures. OBJECTIVE: The Sister Study sought a large cohort of women never diagnosed with breast cancer but who had a sister (full or half) diagnosed with breast cancer. METHODS: A multifaceted national effort employed novel strategies to recruit a diverse cohort, and collected biological and environmental samples and extensive data on potential breast cancer risk factors. RESULTS: The Sister Study enrolled 50,884 U.S. and Puerto Rican women 35-74 y of age (median 56 y). Although the majority were non-Hispanic white, well educated, and economically well off, substantial numbers of harder-to-recruit women also enrolled (race/ethnicity other than non-Hispanic white: 16%; no college degree: 35%; household income <$50,000: 26%). Although all had a biologic sister with breast cancer, 16.5% had average or lower risk of breast cancer according to the Breast Cancer Risk Assessment Tool (Gail score). Most were postmenopausal (66%), parous with a first full-term pregnancy <30 y of age (79%), never-smokers (56%) with body mass indexes (BMIs) of <29:9 kg=m² (70%). Few (5%) reported any cancer prior to enrollment. CONCLUSIONS: The Sister Study is a unique cohort designed to efficiently study environmental and genetic risk factors for breast cancer. Extensive exposure data over the life-course and baseline specimens provide important opportunities for studying breast cancer and other health outcomes in women. Collaborations are welcome.

Objective: We aimed to assess the relative validity and reproducibility of a semi-quantitative FFQ in Puerto Rican adults.Design: Participants completed an FFQ, followed by a 6 d food record and a second administration of the FFQ, 30 d later. All nutrients were log transformed and adjusted for energy intake. Statistical analyses included correlations, paired t tests, cross-classification and Bland-Altman plots.Setting: Medical Sciences Campus, University of Puerto Rico.Subjects: Convenience sample of students, employees and faculty members (n 100, ≥21 years). Data were collected in 2010.Results: A total of ninety-two participants completed the study. Most were young overweight females. All nutrients were significantly correlated between the two FFQ, with an average correlation of 0·61 (range 0·43-0·73) and an average difference of 4·8 % between them. Most energy-adjusted nutrients showed significant correlations between the FFQ and food record, which improved with de-attenuation and averaged 0·38 (range 0·11-0·63). The lowest non-significant correlations (≤0·20) were for trans-fat, n 3 fatty acids, thiamin and vitamin E. Intakes assessed by the FFQ were higher than those from the food record by a mean of 19 % (range 4-44 %). Bland-Altman plots showed that there was a systematic trend towards higher estimates with the FFQ, particularly for energy, carbohydrate and Ca. Most participants were correctly classified into the same or adjacent quintile (average 66 %) by both methods with only 3 % gross misclassification.Conclusions: This semi-quantitative FFQ is a tool that offers relatively valid and reproducible estimates of energy and certain nutrients in this group of mostly female Puerto Ricans.
