The global work environment requires graduates to have skills to work collaboratively over distance and time. This pilot study presents the findings of a survey of student perceptions concerning a global virtual team (GVT) experience that used both synchronous and asynchronous collaboration. Our findings revealed that while students experienced enhanced cognitive and social learning through the GVT experience, they found the activity to be frustrating and time consuming. However, students acknowledged that the experience was beneficial to their learning and should be incorporated in future course offerings.

Objectives: A bibliometric analysis of articles in the Journal of Ultrasound in Medicine (JUM) identified the journals' most impactful articles. Methods: A bibliometric analysis of citation classics that were published in the JUM from its inception in 1982 to 2019 was performed. All citation classics, defined as articles cited 100 or more times, were evaluated for the number of citations, citations per year, publication year, subspecialty, design, and country of origin. Characteristics were compared before and after 1998 by the Mann‐Whitney test for unpaired data and 2‐sample z tests of sample proportions. The Kruskal‐Wallis test for nonparametric continuous data was used to compare the median number of citations per year by decade of publication. Results: A total of 7868 articles were published in the JUM between 1982 and 2019; 54 (0.7%) were citation classics. The median citation classics year of publication was 1998 (interquartile range [IQR], 1991–2003). Most citation classics originated from the United States (36 of 54 [66.7%]), were observational (47 of 54 [87%]), and were related to obstetric and gynecologic topics (16 of 54 [29.6%]). Citation classics after 1998 received significantly more citations per year (9.3 versus 4.7; P <.001), with no other differences noted. The median number of citations per year increased for each decade, with medians of 4 citations (IQR, 3.6–4.7) in 1982 to 1991 and 11.2 citations (IQR, 9–13.9) in 2002 to 2012 (P <.001). Conclusions: This list provides insight into the most influential articles that were published in the JUM. Most citation classics were observational, were from the United States, and covered obstetric and gynecologic topics. Citation classics received more citations per year after 1998.

Research on polyamorous relationships has increased substantially over the past decade. This work has documented how polyamory is practiced and why individuals might pursue such arrangements. However, there is a lack of a systematic investigation of who is in polyamorous relationships and how they might differ from individuals in monogamous relationships. The present study is one of the first to address this by comparing the demographic backgrounds of individuals in polyamorous (N = 2,428) and monogamous (N = 539) relationships in the United States. Compared to participants in monogamous relationships, those in polyamorous relationships were more likely to report minority sexual identities. Despite similar age distributions, individuals in polyamorous relationships were more likely to report being in a civil union, being divorced, and earning less than $40,000 per year compared to individuals in monogamous relationships. People in polyamorous relationships were also more likely to select "other" options for most demographic characteristics, suggesting that they tend to choose less traditional response options in general. The current research highlights several demographic differences that need to be considered and potentially controlled for in future comparisons of polyamorous and monogamous relationships.

Objectives: To determine if hyperthermic intraperitoneal chemotherapy (HIPEC) is associated with improved survival in patients undergoing cytoreductive surgery (CRS) for newly diagnosed stage III or stage IV ovarian cancer at Commission on Cancer (CoC)-accredited cancer programs in the United States. Methods: The National Cancer Database was queried for patients with stage III or stage IV ovarian cancer undergoing CRS+HIPEC between 2004 and 2017. A control population of patients from 38 HIPEC-performing institutions undergoing CRS only was obtained using propensity score matching and adjusted for facility volume, age, Charlson-Deyo-Comorbidity-Index (CDCI), and stage. All patients in this study underwent complete cytoreduction to no gross residual (NGR) disease. Univariate survival analyses were performed using the log-rank test and adjusted for covariates using Cox proportional hazards regression. All analyses were performed using IBM SPSS Statistics 27. Results: A total of 66 patients who underwent CRS+HIPEC and had available survival data were identified. An additional 66 patients who underwent CRS only at HIPEC performing institutions were included in all comparisons based on propensity score match parameters. Demographics for the CRS+HIPEC group versus the CRS only group revealed no significant difference between median age (58 vs 61 years old) or median CDCI (score 0 vs 0), while significant differences were observed in primary CRS (46% vs 76%) (p<0.001), interval CRS (54% vs 24%) (p<0.001), stage III (65% vs 82%) (p=0.007), and stage IV (35% vs 18%) (p=0.007). Patients undergoing CRS+HIPEC had a significantly higher median overall survival (OS) of 42.1 months (95% CI: 31.8-52.4 months) compared to patients undergoing CRS only, who had a median OS of 34.9 months (95% CI: 23.4-46.4 months, p=0.015). Fifty percent of patients undergoing CRS+HIPEC were still alive at 60 months compared to 30.3% of patients undergoing CRS only. On multivariable analysis, patients undergoing CRS+HIPEC were 38.9% less likely to die compared to those who underwent CRS alone (HR of death: 0.611, 95% CI 0.402-0.928, p=0.021). [Display omitted] Conclusions: On retrospective review of patients undergoing complete CRS for newly diagnosed stage III or stage IV ovarian cancer at CoC-accredited cancer programs in the United States, we found CRS+HIPEC to be associated with significantly improved survival compared to CRS only. These findings are especially notable given the higher proportion of stage IV patients in the CRS+HIPEC group. Thus, stage IV patients who respond well to neoadjuvant chemotherapy and can undergo complete interval CRS should also be considered for HIPEC. [ABSTRACT FROM AUTHOR]

Results of Office of Naval Research (ONR)and National Science Foundation (NSF)-sponsored collaborative coastal science experiments using underwater gliders were reported at the E.U./U.S. Baltic Sea conference in 2006. The National Oceanic and Atmospheric Administration (NOAA) recognized the parallel educational potential and issued a trans-Atlantic challenge-modify one of the coastal gliders and fly it across the Atlantic, entraining and inspiring students along the way. Leveraging the experience of the NSF Centers for Ocean Sciences Education Excellence, a needs assessment process guided the development of a new undergraduate research program based on the cognitive apprenticeship model. The generalized model was applied to the specific opportunities provided by the trans-Atlantic challenge, involving students in every aspect of the missions. Students participated in the modifications and testing required to increase glider endurance and in the development of the mission planning tools. Scientist and student teams conducted three long-duration missions: (1) RU1 5's flight from New Jersey to Nova Scotia to test the lithium batteries and ruggedized fin technology in storms, (2) RU1 7's first attempt at the Atlantic crossing that provided the lessons learned, and (3) RU27's successful trans-Atlantic flight a year later. Post-flight activities included development of new intuitive glider data visualization software that enabled students to analyze the glider data and compare it with ocean forecast models, enabling students to create their own new knowledge. Lessons learned include the significant gains achieved by engaging students early, encouraging them to work as teams, giving them the tools to make their own discoveries, and developing a near-peer mentoring community for increasing retention and diversity. The success has inspired an even broader vision for international glider missions, that of a gliderenabled global classroom to repeat the track of the HMS Challenger and its first scientific circumnavigation of the globe.

The Integrated Ocean Observing System (lOOS®) Regional Associations and Interagency Partners hosted a water quality workshop in January 2010 to discuss issues of nutrient enrichment and dissolved oxygen depletion (hypoxia), harmful algal blooms (HABs), and beach water quality. In 2007, the National Water Quality Monitoring Council piloted demonstration projects as part of the National Water Quality Monitoring Network (Network) for U.S. Coastal Waters and their Tributaries in three IOOS Regional Associations, and these projects are ongoing. Examples of integrated science-based solutions to water quality issues of major concern from the IOOS regions and Network demonstration projects are explored in this article. These examples illustrate instances where management decisions have benefited from decision-support tools that make use of interoperable data. Gaps, challenges, and outcomes are identified, and a proposal is made for future work toward a multiregional water quality project for beach water quality. [ABSTRACT FROM AUTHOR]

Autonomous underwater gliders have proven to be a cost-effective technology for measuring the 3-D ocean and now represent a critical component during the design and implementation of the Mid-Atlantic Regional Ocean Observing System (MARCOOS), a Region of the U.S. Integrated Ocean Observing System. The gliders have been conducting regional surveys of the Mid-Atlantic (MA) Bight, and during the 3 years of MARCOOS, the glider fleet has conducted 22 missions spanning 10,867 km and collecting 62,824 vertical profiles of data. In addition to collecting regional data, the gliders have facilitated collaboration for partners outside of MARCOOS. The existence of the MA glider observatory provided a unique test bed for cyber-infrastructure tools being developed as part of the National Science Foundation's Ocean Observatory Initiative. This effort allowed the Ocean Observatory Initiative software to integrate the MARCOOS assets and provided a successful demonstration of an ocean sensor net. The hands-on experience of the MA glider technicians supported training and provided assistance of collaborators within the Caribbean Regional Association, also a region of the U.S. Integrated Ocean Observing System, to assess the efficacy of gliders to resolve internal waves. Finally, the glider fleet has enabled sensor development and testing in a cost-effective manner. Generally, new sensors were tested within the MARCOOS domain before they were deployed in more extreme locations throughout the world's oceans. On the basis of this experience, the goal of the MARCOOS glider team will be to expand the MA network in coming years. The potential of how an expanded network of gliders might serve national needs was illustrated during the 2010 Macondo Gulf of Mexico oil spill, where gliders from many institutions collected subsurface mesoscale data to support regional models and oil response planning. The experience gained over the last 5 years suggests that it is time to develop a national glider network. [ABSTRACT FROM AUTHOR]

The Mid-Atlantic Regional Coastal Ocean Observing System (MARCOOS) High- Frequency Radar Network, which comprises 13 long-range sites, 2 medium-range sites, and 12 standard-range sites, is operated as part of the Integrated Ocean Observing System. This regional implementation of the network has been operational for 2 years and has matured to the point where the radars provide consistent coverage from Cape Cod to Cape Hatteras. A concerted effort was made in the MARCOOS project to increase the resiliency of the radar stations from the elements, power issues, and other issues that can disable the hardware of the system. The quality control and assurance activities in the Mid-Atlantic Bight have been guided by the needs of the Coast Guard Search and Rescue Office. As of May,, 2009, these quality-controlled MARCOOS High-Frequency Radar totals are being served through the Coast Guard's Environmental Data Server to the Coast Guard Search and Rescue Optimal Planning System. In addition to the service to U.S. Coast Guard Search and Rescue Operations, these data support water quality, physical oceanographic, and fisheries research throughout the Mid-Atlantic Bight.

A national high-frequency radar network has been created over the past 20 years or so that provides hourly 2-0 ocean surface current velocity fields in near real time from a few kilometers offshore out to approximately 200 km. This preoperational network is made up of more than 100 radars from 30 different institutions. The Integrated Ocean Observing System efforts have supported the standards-based ingest and delivery of these velocity fields to a number of applications such as coastal search and rescue, oil spill response, water quality monitoring, and safe and efficient marine navigation. Thus, regardless of the operating institution or location of the radar systems, emergency response managers, and other users, can rely on a common source and means of obtaining and using the data. Details of the history, the physics, and the application of high-frequency radar are discussed with successes of the integrated network highlighted. [ABSTRACT FROM AUTHOR]

The risk of ozone injury to plants was assessed in support of the National Park Service''s Vital Signs Monitoring Network program. The assessment examined bioindicator species, evaluated levels of ozone exposure, and investigated soil moisture conditions during periods of exposure for a 5-year period in each park. The assessment assigned each park a risk rating of high, moderate, or low. For the 244 parks for which assessments were conducted, the risk of foliar injury was high in 65 parks, moderate in 46 parks, and low in 131 parks. Among the well-known parks with a high risk of ozone injury are Gettysburg, Valley Forge, Delaware Water Gap, Cape Cod, Fire Island, Antietam, Harpers Ferry, Manassas, Wolf Trap Farm Park, Mammoth Cave, Shiloh, Sleeping Bear Dunes, Great Smoky Mountains, Joshua Tree, Sequoia and Kings Canyon, and Yosemite.

A high-frequency (HF) radar system is deployed on the New Jersey continental shelf as part of a coastal ocean observatory. The system includes two remote transmit–receive sites in Brant Beach and Brigantine, New Jersey, and a central processing site in Tuckerton, New Jersey. The system uses radio waves scattered off the ocean to measure the radial velocity, range, and bearing of the scattering surface. Calculation of the bearing for HF radar systems depends on the actual beam pattern of the receive antennas. A series of antenna beam pattern measurements conducted on the New Jersey system shows that these patterns are often distorted when an antenna is deployed in the field. Tests indicate that the local environment, not system hardware, causes the most significant distortion of the pattern from the theoretical shape. Correlation with an in situ acoustic Doppler current profiler (ADCP) indicates that the beam pattern distortion can bias the bearing estimate. It is shown that this bias can be removed if the measured beam patterns are used to estimate the bearing. [ABSTRACT FROM AUTHOR]

The United States (U.S.) geoscience literature is employed as a vehicle to study the phenomenon of obsolescence. Problems investigated include the classical and ephemeral aspects of subject literatures, diversity among narrowly defined literatures within broadly defined subject literatures, and the effect of literature growth on obsolescence. Comparisons are made: 1. among time-frequency bibliographs based on citation counts from each of twelve major journals published in 1969; 2. between bibliographs of three major journals for the years 1969 and 1949; and 3. between uncorrected and corrected obsolescence curves. Each journal yields citation patterns comprised of both an ephemeral and a classical literature component. Within this framework apparent obsolescence varies across a broad spectrum, from physics/chemistry-oriented geoscience subdisciplines with relatively short "half-lives," to those biology-oriented with relatively long "half-lives," Obsolescence rates of traditional geoscience fields seem to vary little between 1949 and 1969 in contrast to thor of fast-changing fields such as solid earth geophysics. The relationship between obsolescence curves uncorrected and corrected for growth suggests the operation of factors that control research fronts. The effect of literature size on obsolescence, though minor for the recent literature, is more pronounced for the classical literature. [ABSTRACT FROM AUTHOR]

Objectives: The aim of the study was to determine whether sleep quality is associated with an increased risk for cardiovascular disease (CVD) or worsened mental health. Methods: Self-reported sleep quality, 35 inflammatory factors, CVD risk factors, personal stress, police operational and organizational stress, social support, depressive symptoms, and health-related quality of life were compared among a cohort of officers. Results: Of 379 officers, 39% and 27% had poor and borderline sleep quality. Sleep quality was not associated with either an altered inflammatory profile or worsened CVD risk factors. Compared with good sleepers, borderline and poor sleepers reported increased personal stress, police organizational and operational stress, and depressive symptoms, but decreased health-related quality of life. Conclusions: Poor sleep quality is prevalent in the law enforcement profession and is associated with worsened mental health but not with an increased risk for CVD. [ABSTRACT FROM AUTHOR]
