    Mercury is a potent neurotoxin that is transported globally in vapor form. A major source of mercury contamination to soil, water, and biota is atmospheric deposition. Therefore, comprehensive monitoring of atmospheric concentrations is important. Limitations of conventional atmospheric measurement techniques include high cost and lack of temporal or spatial integration. Bioindicators, however, may serve as an integrative tool to add to conventional mercury measurement techniques. Spanish moss (Tillandsia usneoides L.) is a potential bioindicator of atmospheric mercury concentration in the southeastern United States because it is an abundant epiphyte that absorbs and accumulates atmospheric pollutants. A study was conducted in southeastern Georgia and northern Florida to test the hypotheses that 1) Spanish moss absorbs and retains atmospheric mercury in tissue, and 2) atmospheric mercury concentrations differ geographically due to nonpoint emission sources, and the concentration of mercury in Spanish moss tissue reflects these differences. To determine if Spanish moss exhibits uptake and retention of mercury, an experiment was conducted in which I transplanted Spanish moss saturated with mercury vapor in the laboratory to a field site unimpacted by mercury emissions and measured tissue mercury concentration over time. In addition, to determine if mercury concentrations in Spanish moss are reflective of atmospheric concentrations, I conducted two field studies in which the mercury concentrations of both resident and transplanted Spanish moss were compared to atmospheric concentrations at sites with different anthropogenic land use. In all studies, tissue was analyzed for mercury concentration using Inductively-Coupled Plasma Mass Spectrometry. Results suggest Spanish moss absorbs and retains atmospheric mercury, and mercury concentrations in Spanish moss tissue are associated with atmospheric concentrations over both small and large geographic scales. Thus, Spanish moss may serve as a useful measurement tool to add to existing monitoring protocols

    The Influence of Religion and Spirituality on HIV Prevention Among Black and Latino Men Who Have Sex with Men, New York City

    The influence of religion and spirituality (R/S) on HIV prevention has been understudied, especially for Black and/or Latino men who have sex with men (BLMSM), who bear a disproportionate burden of HIV, and who are part of racial/ethnic communities with high engagement in R/S. The specific aim of this study was to explore perspectives about R/S among BLMSM to inform HIV prevention strategies and reduce HIV-related health disparities. Data from 105 qualitative interviews with BLMSM were analyzed; 58 (55%) stated that R/S had no personal influence on HIV prevention. For those reporting any R/S influence, main themes were: (1) R/S positively influenced decision-making and self-respect, (2) perceived judgment and stigma by religious communities, (3) belief in a higher power, and (4) altruism. These findings can inform faith-based HIV prevention interventions for BLMSM

    “My Sexuality…It Creates a Stress”: HIV-Related Communication Among Bisexual Black and Latino Men, New York City

    Men who have sex with men and women (including bisexual men) comprise 35% of all men who have sex with men (MSM) in the U.S. It is estimated that 121,800 men who have been bisexually active within the past year are living with HIV in the U.S. Communication about HIV may result in risk-reduction behaviors. However, little is known about the nature or context for HIV prevention communication among bisexual men, particularly for blacks and Hispanic/Latinos who are disproportionately at greater HIV risk. Therefore, we explored patterns and contexts of HIV-related communications occurring within personal social networks among bisexual black and Hispanic/Latino men. Using respondent-driven sampling methods, we conducted semi-structured interviews from 2011 to 2012 among 36 participants living in New York City. We examined interview responses from participants for main themes using computer-assisted thematic analyses. The three main themes identified were: (1) communication strategies (e.g., “You can tell a lot from how a person responds just by the tone of their voice”), (2) barriers (e.g., “My sexuality…it creates a stress”), and (3) motivations for these communications (e.g., “I know that’s a(n) issue in the black community…if I could help another brother, I will do it”). Our findings can inform HIV prevention efforts such as social messaging campaigns and other risk-reduction interventions designed for bisexual men

    “Take Off 4-Health�: Nutrition Education Curriculum for a Healthy Lifestyle Camp for Overweight Youth

    There is evidence that residential summer weight loss camps can be effective to initiate or support the small change approach to address childhood obesity. This report describes the development and evaluation of nutrition education for overweight adolescents attending a three week healthy lifestyle camp. Campers were given a diet prescription based on MyPryamid and self-selected their meals and snacks that were served family style. The curriculum included eating strategies known to contribute to healthy weight in youth. Campers demonstrated improved ability to estimate portion sizes. Thirty-four campers completed the three week experience with a weight loss considered to be safe. Note: the deposited item is not the final published version, but rather is the last revised manuscript sent to the publisher

    Factors influencing the provision of end-of-life care for adolescents and young adults with advanced cancer: a scoping review

    Background There is international recognition that cancer in young people is on the rise and that improvements in outcomes for young people lag well behind advances achieved for both children and older adults over the past 30 years. Cancer is the third leading cause of death in adolescents and young adults; however, little is known about how the end of life unfolds for those who die of the progressive disease. Objective This scoping review sought to locate and describe literature relating to end of life care for adolescents and young adults with cancer

    Objective: To explore the processes and opportunities provided in the co-curriculum of the Wegmans School of Pharmacy (WSoP) that contribute to the development of successful pharmacy graduates. Methods: Pharmacy career preparation begins at orientation with workshops on emotional intelligence, leadership, and the APhA Career Pathway Evaluation Program. During the P1 through P4 years, the optional Student Development Workshop Series (SDW) offers seminars for students on a variety of topics including time management, exam taking strategies/anxiety management, learning styles, personal “brand” creation, CV/portfolio development, and interview soft skills. All students may participate in the annual WSoP Career Day, which offers networking and career opportunities, including post-graduate training options. During the P4 year, there is opportunity for a structured Residency/Fellowship Preparation Program (RPP). Additionally, local pharmacy residents/fellows participate in a Residency Teaching/Learning Curriculum Program (TLC) to develop academic teaching and precepting skills. Results: The SDW program has been successful and well attended with greater than 90% of students finding the topics relevant to their post-graduate success. After the RPP, ASHP residency match results in the 2016 class yielded an improvement from previous years, with 76 % of applied students and 94% of ranked students matching programs in Phase 1. Of the TLC participants, 90% documented an improvement in multiple types of teaching skills. Implications: Based on data and student/faculty input, career development is reassessed and improved continuously at WSoP. In the near future, a method for tracking graduates will be designed to further monitor the impact of programs on student success

    The acquisition of Sign Language: The impact of phonetic complexity on phonology

    Research into the effect of phonetic complexity on phonological acquisition has a long history in spoken languages. This paper considers the effect of phonetics on phonological development in a signed language. We report on an experiment in which nonword-repetition methodology was adapted so as to examine in a systematic way how phonetic complexity in two phonological parameters of signed languages — handshape and movement — affects the perception and articulation of signs. Ninety-one Deaf children aged 3–11 acquiring British Sign Language (BSL) and 46 hearing nonsigners aged 6–11 repeated a set of 40 nonsense signs. For Deaf children, repetition accuracy improved with age, correlated with wider BSL abilities, and was lowest for signs that were phonetically complex. Repetition accuracy was correlated with fine motor skills for the youngest children. Despite their lower repetition accuracy, the hearing group were similarly affected by phonetic complexity, suggesting that common visual and motoric factors are at play when processing linguistic information in the visuo-gestural modality
