Effects of Dehydration Stress on the Dark Adapted Fluorescence (Fv/Fm) of Giant Bladder Kelp (Macrocystis pyrifera)

The unique semi-diurnal tide system of Southern California suspends beach wrack along the beaches for approximately six hour periods before being washed back into the ocean. It has been noted in prior research that beach wrack is an essential part of Southern California\u27s costal ecology but not much research has been done to learn about the viability of beach wrack as it dehydrates on the beach. To better understand the viability of wrack as it travels through these hydration changes, this study tested the effect of dehydration and rehydration on the fronds of Macrocystis pyrifera as they have been partially dehydrated and re-hydrated. This was tested by measuring the Fv/Fm, using a pulse-modulated fluorometer, and the change in water mass of selected fronds over a six hour dehydration period, and three hour re-hydration period. It was found that there was a significant increase of Fv/Fm and water mass after rehydration. However our studies showed that Fv/Fm surprisingly continued to increase as the plant was dehydrated and a chi-square test verified that the values of the rehydrated plants were not independent of the dehydrated values

Small-scale commercial fishing in southern New England

This description of the small-scale sector of the Southern New England (Massachusetts, Rhode Island and Connecticut) fishery includes information on the fishermen (their ages, education, experience, occupational training, family involvement and reasons for fishing) and the physical characteristics of the fleet (the boats and gear). Fishing patterns are analyzed by species, geographical areas and seasons. The economic structure of small-scale fishing is described in terms of investment, net and gross earnings, fuel costs, crew payments systems and marketing arrangements. Management implications of this information and analyses are included.Prepared for the Pew Memorial Trust, for the Department of Commerce, NOAA, Office of Sea Grant, under Grants 04-8-M01-149, also NA 79AA-D-00102, and for Woods Hole Oceanographic Institution's Marine Policy and Ocean Management Program

New England fishing, processing and distribution

The New England fishing industry is examined in terms of the capacity of the fishing fleet, of the processing plants, and of the transportation system. Limitations on the capacity of the industry, and its capability and flexibility, are explored in terms of social, economic and technical aspects. The study is based on interviews with fishermen, buyers, processors and distributors, and on data made available by the National Marine Fisheries Service. Although the fisheries is in a state of expansion and both vessels and plants have a greater capacity than is now being used, the major problems that may restrict expansion in both fishing and processing are quality control, species selection and market development.This document is the final report for NOAA Contract #03-6-043-35165, which supported most of the research.

Promoting Holistic Wellness in Honors Students through Peer Coaching

While the conversation in honors about the mental health of students has persisted for over two decades, authors identify a marked increase in the need for student mental health support since the first Generation Z students entered college in 2015. A review of literature in honors indicates upticks in discourse relating to mental health (tn = 66) since 2004, and content analysis shows peaks in publication for 2018 and 2021 (n ≠ 11, respectively). This study describes a peer coaching program that focuses on the holistic wellness and support of honors students. Authors observe a decrease in Behavioral Intervention Team meetings and suicide attempts since the program’s inception in 2015. Programmatic details, including application and selection, training, expectations of peer coaches, assessment, and improvement initiatives are included so that similar programs can be implemented in and beyond honors

Bibliography of socio-economic studies : fisheries of the northeast U.S.

This bibliography of social and economic studies of the fisheries of the Northeast United States (Maine to North Carolina) includes annotated listings for each entry and an index of key words for cross-referencing. We have attempted to include all studies published since 1970, and a selected group of particularly significant studies done earlier. The major focus has been on commercial fisheries, but recreational fishing studies have also been included when possible. In addition to studies of the Northeast United States fisheries, studies of Canadian fishing subsidies, European and other markets, have been included because of their relevance to the regional industry. All stages of the fishing industry's operation - harvesting, processing, distribution, marketing - are included, along with management and policy oriented material.Prepared for the National Marine Fisheries Service Contract NA-81-FA-C-00018 and for The Pew Memorial Trust, also for the Department of Commerce, NOAA Office of Sea Grant under NA-80AA-D-0077 (E/L-1) and the Institution's Marine Policy and Ocean Management Program

Novel mutation in CCBE 1 as a cause of recurrent hydrops fetalis from Hennekam lymphangiectasia-lymphedema syndrome-1.

Whole exome sequencing (WES) was used to determine the etiology of recurrent hydrops fetalis in this case of Hennekam lymphangiectasia-lymphedema syndrome-1. WES is a useful approach for diagnosing rare single-gene conditions with nonspecific phenotypes and should be considered early in the diagnostic process of investigating fetal abnormalities

Assessing Large-Scale Training Events: Developing Common Tools and Protocols

Numerous previous studies have shown the positive effects that simulators provide in training aircrew for both basic maneuvering and more advanced team combat skills. As technology evolves, we have the ability to connect simulators separated by great geographic distance and often in different countries, thus allowing an even greater number of aircrew to train together as a team. In addition, live-fly training events provide an excellent opportunity to train aircrew. However, these large-scale distributed and live-fly training events must be examined for effectiveness. To accomplish this, training assessors must use a common set of data collection instruments, and follow a common protocol that says when to use them, and who should use each one. This is particularly important in distributed simulation exercises where training participants (and assessors) may be located at a number of geographically dispersed sites. The Air Force Research Laboratory along with its international partners has developed a set of knowledge, skill and experience based surveys that can be used to evaluate large scale distributed training events. In addition, we have developed a protocol that specifically describes when each survey should be given, and to whom. These events pose unique challenges in data collection; therefore, in addition to traditional paper surveys, we have developed a website and “minibrowser” that can run on a stand alone, non-networked computer to collect data from participants. These tools, protocols and data collection methods have already been successfully used at a number of large scale distributed events. This paper will present data and results from US and multinational applications of the methods and tools, discuss feedback and lessons learned. We will discuss and highlight the latest versions of the tools, protocol and methods we have developed, and present the future directions we hope to take with this researc

Doctoral Students’ Perceived Barriers that Slow the Progress toward Completing a Doctoral Dissertation: A Mixed Analysis

The non-completion of doctoral degrees has been a concern due to its economic, social, and personal consequences. In the current study, the researchers investigated perceived barriers of select doctoral students in completing their doctoral degrees by utilizing a fully mixed sequential mixed research design. The quantitative and qualitative data were concurrently collected using identical samples (n = 205) via a Reading Interest Survey questionnaire. A sequential mixed analysis revealed 6 emergent themes: external obligations (36%), challenges to doctoral-level researchers (34%), practical/logistical constraints (23%), emotional concerns (15%), program structure (9%), and support for completion (8%). Also, 3 meta-themes were identified (i.e., dissociation, external/internal barriers, and institutional/personal barriers), which aided in explaining the relationships among the 6 primary themes. Implications of the findings are discussed

'Has she seen me?':A multiple methods study of the pharmaceutical care needs of older people with sensory impairment in Scotland

Objectives To explore the pharmaceutical care needs of, and service provision to, older people with sensory impairment (visual, hearing and dual impairment) on prescribed polypharmacy (≥4 medicines) in Scotland. Design Interviews were conducted with older people with sensory impairment and community pharmacy personnel, which informed the content of a subsequent national cross-sectional survey of community pharmacists. Setting Scotland, 2015–2016. Participants Older people with sensory impairment and community pharmacy personnel. Results Interviews were completed with 23 older people with sensory impairment (dual impairment n=13, visual or hearing impairment n=5 of each) and 30 community pharmacy personnel from eight of 14 Scottish Health Boards. A total of 171 survey responses were received. Older people reported that they did not always disclose their sensory impairment to pharmacy personnel. They also reported that medicines were difficult to identify particularly when their name, shape or colour changed. Pharmacy personnel relied on visible cues such as white canes or guide dogs to identify visual impairment and suggested that hearing loss was less visible and more difficult to identify. Many assistive aids in support of medicine management, such as dosette boxes, seemed inadequate for complex medication regimens. Few community pharmacy personnel reported receiving training in the care of people with sensory impairment. Conclusions This is the first comprehensive, multistakeholder, in-depth exploration of the pharmaceutical care needs of older people with sensory impairment. Strategies are needed to enable people with sensory impairment to disclose their impairment to pharmacy personnel (and other healthcare providers). Community pharmacy personnel require training to deliver person-centred pharmaceutical care for older people with sensory impairment particularly regarding communication with individuals in this vulnerable population

SN2012ab: A Peculiar Type IIn Supernova with Aspherical Circumstellar Material

We present photometry, spectra, and spectropolarimetry of supernova (SN) 2012ab, mostly obtained over the course of $\sim 300$ days after discovery. SN 2012ab was a Type IIn (SN IIn) event discovered near the nucleus of spiral galaxy 2MASXJ12224762+0536247. While its light curve resembles that of SN 1998S, its spectral evolution does not. We see indications of CSM interaction in the strong intermediate-width emission features, the high luminosity (peak at absolute magnitude $M=-19.5$), and the lack of broad absorption features in the spectrum. The H$\alpha$ emission undergoes a peculiar transition. At early times it shows a broad blue emission wing out to $-14{,}000$ km $\mathrm{s^{-1}}$ and a truncated red wing. Then at late times ($>$ 100$\,$days) it shows a truncated blue wing and a very broad red emission wing out to roughly $+20{,}000$ km $\mathrm{s^{-1}}$. This late-time broad red wing probably arises in the reverse shock. Spectra also show an asymmetric intermediate-width H$\alpha$ component with stronger emission on the red side at late times. The evolution of the asymmetric profiles requires a density structure in the distant CSM that is highly aspherical. Our spectropolarimetric data also suggest asphericity with a strong continuum polarization of $\sim 1-3$% and depolarization in the H$\alpha$ line, indicating asphericity in the CSM at a level comparable to that in other SNe IIn. We estimate a mass-loss rate of $\dot{M} = 0.050\, {\rm M}_{\odot}\,\mathrm{yr^{-1}}$ for $v_{\rm pre} = 100$$\,$km$\,$$\mathrm{s^{-1}}$ extending back at least 75$\,$yr prior to the SN. The strong departure from axisymmetry in the CSM of SN 2012ab may suggest that the progenitor was an eccentric binary system undergoing eruptive mass loss.Comment: 18 pages, 12 figure
