Consumption of kiwifruit capsules increases Faecalibacterium prausnitzii abundance in functionally constipated individuals: a randomised controlled human trial

This study investigated the impact of ACTAZIN™ green (2400 and 600 mg) and Livaux™ (2400 mg) gold kiwifruit supplements on faecal microbial composition and metabolites in healthy and functionally constipated (FC) participants. The participants were recruited into the healthy group (n 20; one of whom did not complete the study) and the FC group (n 9), each of whom consumed all the treatments and a placebo (isomalt) for 4 weeks in a randomised cross-over design interspersed with 2-week washout periods. Modification of faecal microbiota composition and metabolism was determined by 16S rRNA gene sequencing and GC, and colonic pH was calculated using SmartPill® wireless motility capsules. A total of thirty-two taxa were measured at greater than 1 % abundance in at least one sample, ten of which differed significantly between the baseline healthy and FC groups. Specifically, Bacteroidales and Roseburia spp. were significantly more abundant (P < 0·05) in the healthy group and taxa including Ruminococcaceae, Dorea spp. and Akkermansia spp. were significantly more abundant (P < 0·05) in the FC group. In the FC group, Faecalibacterium prausnitzii abundance significantly increased (P = 0·024) from 3·4 to 7·0 % following Livaux™ supplementation, with eight of the nine participants showing a net increase. Lower proportions of F. prausnitzii are often associated with gastrointestinal disorders. The discovery that Livaux™ supplementation increased F. prausnitzii abundance offers a potential strategy for improving gut microbiota composition, as F. prausnitzii is a butyrate producer and has also been shown to exert anti-inflammatory effects in many studies

Adaptation of Ecuadorian National Music for Chamber Music Ensemble

This project was to take Ecuadorian national music and transform it for the students at WPI to increase the community’s cultural awareness and make Ecuadorian music more accessible. Three different styles were arranged for a combined instrumental and choral ensemble of WPI students using the skills learned from classes in music theory, arranging and orchestration, performance, and conducting. The result was arrangements of Vasija de Barro, Corazόn Herido and Nuestro Juramento for an ensemble of 31 musicians

Permaculture Design Plan for María Amor Foundation, Cuenca Ecuador

The María Amor Foundation, a women’s shelter for domestic abuse victims, sits on a largely unused plot of land. The goal of our project was to design an integrated land-use plan to provide food for internal use as well as to sell. Onsite we interviewed employees of the foundation and visited local farms to learn about the needs of the foundation and local agriculture practices. Our final design included functional, sustainable features which allows the shelter to serve as a safe space for women to recover and reconnect with nature. We left the property with suggestions on how to evolve to be completely self-sustaining

The Grand Challenge of Ending Homelessness

The notion that homelessness in the United States can be ended, rather than managed, represents a fundamental shift in expectations that has occurred over the past three decades. Many U.S. cities now have plans to end homelessness. Yet homelessness and housing instability are substantial problems that afflict a diverse group of subpopulations such as families, youth, veterans, and chronically homeless single adults. Ending homelessness for each of these populations may require tailored interventions that are responsive to specific individualized needs. These factors make tackling homelessness a difficult task. Although evidencebased solutions exist for some subpopulations, such as housing first for chronically homeless adults, scaling up best practices remains a challenge. For other subpopulations, such as transitional aged youth, evidence-based interventions need to be developed. In this paper we argue that ending homelessness is a Grand Challenge that is big, important, and compelling—one that the profession of social work should be adopt. Meeting this challenge will require a focused, organized response from social work researchers, clinicians, and policymakers. Ending homelessness will require innovation and interdisciplinary or cross-sector collaboration

Revitalization of the Riverlands: Trail Design in Sturbridge, MA

The goal of this project was to design a trail connecting the Commercial Tourist District in Sturbridge, Massachusetts to the town’s existing trails network. Through collaboration with the Trails Committee and data collection during site visits, the team developed a design using ArcMap and Civil3D that aligns with the Town’s emphasis on sustainability and environmental impact. The project included considerations for delineations, materials, and steep slopes, as well as cost estimate calculations, stormwater analysis calculations, and stormwater management design

Visual Literacy Intervention for Improving Undergraduate Student Critical Thinking of Global Sustainability Issues

The promotion of global sustainability within environmental science courses requires a paradigm switch from knowledge-based teaching to teaching that stimulates higher-order cognitive skills. Non-major undergraduate science courses, such as environmental science, promote critical thinking in students in order to improve the uptake of scientific information and develop the rational decision making used to make more informed decisions. Science, engineering, technology and mathematics (STEM) courses rely extensively on visuals in lectures, readings and homework to improve knowledge. However, undergraduate students do not automatically acquire visual literacy and a lack of intervention from instructors could be limiting academic success. In this study, a visual literacy intervention was developed and tested in the face-to-face (FTF) and online sections of an undergraduate non-major Introduction to Environmental Science course. The intervention was designed to test and improve visual literacy at three levels: (1) elementary&mdash;identifying values; (2) intermediate&mdash;identifying trends; and (3) advanced&mdash;using the data to make projections or conclusions. Students demonstrated a significant difference in their ability to answer elementary and advanced visual literacy questions in both course sections in the pre-test and post-test. Students in the face-to-face course had significantly higher exam scores and higher median assessment scores compared to sections without a visual literacy intervention. The online section did not show significant improvements in visual literacy or academic success due to a lack of reinforcement of visual literacy following the initial intervention. The visual literacy intervention shows promising results in improving student academic success and should be considered for implementation in other general education STEM courses

Effects of ovarian fluid and genetic differences on sperm performance and fertilization success of alternative reproductive tactics in Chinook salmon

In many species, sperm velocity affects variation in the outcome of male competitive fertilization success. In fishes, ovarian fluid (OF) released with the eggs can increase male sperm velocity and potentially facilitate cryptic female choice for males of specific phenotypes and/or genotypes. Therefore, to investigate the effect of OF on fertilization success, we measured sperm velocity and conducted in vitro competitive fertilizations with paired Chinook salmon (Oncorhynchus tshawytscha) males representing two alternative reproductive tactics, jacks (small sneaker males) and hooknoses (large guarding males), in the presence of river water alone and OF mixed with river water. To determine the effect of genetic differences on fertilization success, we genotyped fish at neutral (microsatellites) and functional [major histocompatibility complex (MHC) II ß1] markers. We found that when sperm were competed in river water, jacks sired significantly more offspring than hooknoses; however, in OF, there was no difference in paternity between the tactics. Sperm velocity was significantly correlated with paternity success in river water, but not in ovarian fluid. Paternity success in OF, but not in river water alone, was correlated with genetic relatedness between male and female, where males that were less related to the female attained greater paternity. We found no relationship between MHC II ß1 divergence between mates and paternity success in water or OF. Our results indicate that OF can influence the outcome of sperm competition in Chinook salmon, where OF provides both male tactics with fertilization opportunities, which may in part explain what maintains both tactics in nature
