A Comparison of Vocabulary Banks and Scripts on Native English-speaking Students’ Acquisition of Italian

The study applied behavior analytic principles to foreign language instruction in a college classroom. Two study methods, vocabulary banks and scripts, were compared by assessing the effects on Italian language acquisition, retention, and generalization. Results indicate that students without prior exposure to Italian engaged in more exchanges and emitted more words in script tests compared to vocabulary bank tests. Participants with at least two classes in Italian prior to the study engaged in more exchanges and emitted more words during vocabulary bank tests. Data suggest that different teaching strategies may work for different learners. More research is needed to determine efficient teaching methods and how to ascertain which approaches work best for learners with different histories

Factors Impacting Adherence to a Multifactorial Fall Prevention Program - a Matter of Balance

BACKGROUND AND PURPOSE: Falls among community dwelling older adults are a significant public health problem. “A Matter of Balance” (MOB) is a multifactorial fall prevention program that aims to improve participants’ self-efficacy and increase physical activity in order to reduce falls. Although there is some evidence supporting MOB’s effectiveness, no published studies to date have examined the program from the perspective of participants or long-term program adherence. As such, the purpose of this study was to examine self-reported outcomes associated with the MOB program in order to explore participants’ perspectives and program adherence. METHODS: This study utilized a mixed methods design that incorporated both survey and focus group interview data. Subjects included a convenience sample of 28 healthy community dwelling older adults who were enrolled in 4 separate MOB programs in the Twin Cities. Survey data were collected before the program and immediately after, 6-weeks, and 6-months post-program. Survey items addressed demographics, general health, falls management, exercise behavior, and number of falls. Focus groups were scheduled 3 to 5 months post-program and led by a principle investigator and student researchers. Semi-structured interview questions focused on participants’ experience of the MOB program, recommendations that were or were not implemented, and motivation for and barriers to change. RESULTS: 70.4% of the participants completed all 4 surveys. Statistically significant improvements were identified for 2 survey items including: “I can find a way to reduce falls” and “I can protect myself if I fall”. No significant change over time in exercise level or number of falls was identified. Ten subjects participated in 4 focus groups. Qualitatively, 7 themes emerged from the focus group data. These were: awareness, motivators for attendance, class learning environment, current adherence, facilitators and barriers to adherence, and recommendations for future programming. CONCLUSION: Overall, MOB’s effectiveness was evidenced by increased awareness, which may be related to improved falls management, self-efficacy and motivation. Post-program adherence to physical activity recommendations was facilitated when activities were incorporated into participants’ existing routines. Participants desired a follow-up program for continued social support and accountability but further research is needed to investigate the efficacy of this type of intervention

Sustainable Markets: Case Study Of Toyota Motor Sales, U.S.A., Inc.

“The traditional definition of sustainability calls for policies and strategies that meet society’s present needs without compromising the ability of future generations to meet their own needs (1).”  Sustainability is a concern in private and public sectors all over the world; it is an issue that resonates with people in all age ranges, income levels, and geographic locations.  The main idea of sustainability is “reduce, reuse, and recycle.”  People and organizations alike must consider every possible effect from the decisions they make in regards to the environment.  With over 600,000,000 passenger cars on the road in the world, and over 50,000,000 passenger cars built each year, it is imperative that automakers make sustainable decisions (2).  It is not just the large number of vehicles in the world that is cause for concern, but the immense amount of resources needed to manufacture, transport, and fuel them.  Automakers must consider the impact that each car has during every stage of its life cycle, in addition to their responsibility to society (in terms of the environment, education, and safety) and the impact of their suppliers.  This case study is designed to discuss the background of Toyota and highlight the company’s current actions in regard to sustainable marketing; a comparison will also be made to the sustainable efforts of Honda and Subaru

Sustainable Markets: Case Study Of Heinz

“The traditional definition of sustainability calls for policies and strategies that meet society’s present needs without compromising the ability of future generations to meet their own needs.”1 Sustainability is a concern in private and public sectors all over the world; it is an issue that resonates with people in all age ranges, income levels, and geographic locations. The main idea of sustainability is “reduce, reuse, and recycle.” People and organizations alike must consider every possible effect from the decisions they make in regards to the environment. Sustainability is a challenge in each and every industry, but with the consistent consumption of numerous resources, it is also a necessity. The food industry, like many others, has begun a transformation of its production processes. Drastic changes are being made in the areas of energy consumption, packaging, emissions, and waste. In the United States, between the years 2005 and 2010, “more than 1.5 billion pounds of packaging was diverted from landfills.” The goal is increase that number by another 2.5 billion pounds in the next ten years. As of now, the food and beverage industry “is on track to reduce packaging weight by 19 percent, or 2.5 billion pounds, by 2020. That’s the energy-saving equivalent of removing 363,000 homes or 815,000 gas-guzzlers.”2 (Cacciola, 2011) As to be expected, Heinz is at the front of the line when it comes to sustainability and originality. The company’s sustainable goals are right in line with the industry and the U.S. Government. Three of the sustainable goals Heinz lists are: (1) reducing GHG emissions by twenty percent of the next ten years, (2) reduce energy consumption by 20%, and (3) reduce packaging by 15%.3 (The Seed of Heinz's Success, 2011

Potential Virus-Mediated Nitrogen Cycling in Oxygen-Depleted Oceanic Waters

Viruses play an important role in the ecology and biogeochemistry of marine ecosystems. Beyond mortality and gene transfer, viruses can reprogram microbial metabolism during infection by expressing auxiliary metabolic genes (AMGs) involved in photosynthesis, central carbon metabolism, and nutrient cycling. While previous studies have focused on AMG diversity in the sunlit and dark ocean, less is known about the role of viruses in shaping metabolic networks along redox gradients associated with marine oxygen minimum zones (OMZs). Here, we analyzed relatively quantitative viral metagenomic datasets that profiled the oxygen gradient across Eastern Tropical South Pacific (ETSP) OMZ waters, assessing whether OMZ viruses might impact nitrogen (N) cycling via AMGs. Identified viral genomes encoded six N-cycle AMGs associated with denitrification, nitrification, assimilatory nitrate reduction, and nitrite transport. The majority of these AMGs (80%) were identified in T4-like Myoviridae phages, predicted to infect Cyanobacteria and Proteobacteria, or in unclassified archaeal viruses predicted to infect Thaumarchaeota. Four AMGs were exclusive to anoxic waters and had distributions that paralleled homologous microbial genes. Together, these findings suggest viruses modulate N-cycling processes within the ETSP OMZ and may contribute to nitrogen loss throughout the global oceans thus providing a baseline for their inclusion in the ecosystem and geochemical models

Recruitment and reach in a school-based pediatric obesity intervention trial in rural areas

Introduction: The purpose of this study is to evaluate two recruitment strategies on schools and participant participation rates and representativeness (reach) within a pediatric obesity treatment trial tailored for families who live in rural areas. Methods: Recruitment of schools was evaluated based on their progress toward enrolling participants. Recruitment and reach of participants were evaluated using (1) participation rates and (2) representativeness of demographics and weight status of participants compared to eligible participants (who did not consent and enroll) and all students (regardless of eligibility). School recruitment, as well as participant recruitment and reach, were evaluated across recruitment methods comparing opt-in (i.e., caregivers agreed to allow their child to be screened for eligibility) vs. screen-first (i.e., all children screened for eligibility). Results: Of the 395 schools contacted, 34 schools (8.6%) expressed initial interest; of these, 27 (79%) proceeded to recruit participants, and 18 (53%) ultimately participated in the program. Of schools who initiated recruitment, 75% of schools using the opt-in method and 60% of schools using the screen-first method continued participation and were able to recruit a sufficient number of participants. The average participation rate (number of enrolled individuals divided by those who were eligible) from all 18 schools was 21.6%. This percentage was higher in schools using the screen-first method (average of 29.7%) compared to schools using the opt-in method (13.5%). Study participants were representative of the student population based on sex (female), race (White), and eligibility for free and reduced-price lunch. Study participants had higher body mass index (BMI) metrics (BMI, BMIz, and BMI%) than eligible non-participants. Conclusions: Schools using the opt-in recruitment were more likely to enroll at least 5 families and administer the intervention. However, the participation rate was higher in screen-first schools. The overall study sample was representative of the school demographics

The JWST Early Release Science Program for the Direct Imaging and Spectroscopy of Exoplanetary Systems

The direct characterization of exoplanetary systems with high-contrast imaging is among the highest priorities for the broader exoplanet community. As large space missions will be necessary for detecting and characterizing exo-Earth twins, developing the techniques and technology for direct imaging of exoplanets is a driving focus for the community. For the first time, JWST will directly observe extrasolar planets at mid-infrared wavelengths beyond 5 μm, deliver detailed spectroscopy revealing much more precise chemical abundances and atmospheric conditions, and provide sensitivity to analogs of our solar system ice-giant planets at wide orbital separations, an entirely new class of exoplanet. However, in order to maximize the scientific output over the lifetime of the mission, an exquisite understanding of the instrumental performance of JWST is needed as early in the mission as possible. In this paper, we describe our 55 hr Early Release Science Program that will utilize all four JWST instruments to extend the characterization of planetary-mass companions to ∼15 μm as well as image a circumstellar disk in the mid-infrared with unprecedented sensitivity. Our program will also assess the performance of the observatory in the key modes expected to be commonly used for exoplanet direct imaging and spectroscopy, optimize data calibration and processing, and generate representative data sets that will enable a broad user base to effectively plan for general observing programs in future Cycles

Factors influencing terrestriality in primates of the Americas and Madagascar

Among mammals, the order Primates is exceptional in having a high taxonomic richness in which the taxa are arboreal, semiterrestrial, or terrestrial. Although habitual terrestriality is pervasive among the apes and African and Asian monkeys (catarrhines), it is largely absent among monkeys of the Americas (platyrrhines), as well as galagos, lemurs, and lorises (strepsirrhines), which are mostly arboreal. Numerous ecological drivers and species-specific factors are suggested to set the conditions for an evolutionary shift from arboreality to terrestriality, and current environmental conditions may provide analogous scenarios to those transitional periods. Therefore, we investigated predominantly arboreal, diurnal primate genera from the Americas and Madagascar that lack fully terrestrial taxa, to determine whether ecological drivers (habitat canopy cover, predation risk, maximum temperature, precipitation, primate species richness, human population density, and distance to roads) or species-specific traits (body mass, group size, and degree of frugivory) associate with increased terrestriality. We collated 150,961 observation hours across 2,227 months from 47 species at 20 sites in Madagascar and 48 sites in the Americas. Multiple factors were associated with ground use in these otherwise arboreal species, including increased temperature, a decrease in canopy cover, a dietary shift away from frugivory, and larger group size. These factors mostly explain intraspecific differences in terrestriality. As humanity modifies habitats and causes climate change, our results suggest that species already inhabiting hot, sparsely canopied sites, and exhibiting more generalized diets, are more likely to shift toward greater ground use.Fil: Eppley, Timothy M..
