    What is a library liaison to do when traditional outreach strategies aren’t working and you can\u27t get buy-in by faculty for instruction sessions for undergraduates? This session will explore the alternative methods of outreach I used to try to “crack” the business school in the absence of in-class instruction opportunities, including a focus on connecting with college staff, direct communication with students through existing college communication channels, and targeted outreach to subsets of students, including international students

    This study examines maternal communication at menarche and its effects on early sexual decision-making in young adult women. Drawing on principles from Bandura’s social cognitive learning theory and communication privacy management theory, I predicted that certain types of maternal communication at menarche would either promote or inhibit early sexual self-efficacy, with indirect effects on age at first sexual intercourse. I also predicted that maternal communication at menarche would vary in tone or content, depending on age at menarche, with mothers communicating less to daughters who reached the milestone early. A total of 175 sexually active females aged 18 to 26 years completed an anonymous online survey that assessed their menarcheal experience, various attitudes and beliefs, and sexual outcomes. I used binary logistic regression to examine hypothesized relationships between maternal communication at menarche, emerging sexual self-efficacy, and age at first sexual intercourse. Findings supported the prediction that emerging sexual self-efficacy mediated the association between maternal tone and delayed first sexual intercourse. Accordingly, girls who received maternal communication at menarche that was positive in tone were more likely to feel comfortable obtaining sexual health information at sexual debut and therefore more likely to delay sexual initiation. No differences were found in maternal communication associated with age at menarche. However, early-maturing participants were more likely to report that they did not know what to expect at menarche and were uncomfortable obtaining sexual health information when they were first becoming sexually active. Age at menarche was found to moderate the association between maternal communication at menarche and emerging sexual self-efficacy. Accordingly, early-maturing participants whose mothers provided factual content at menarche were more likely to report that they were comfortable obtaining sexual health information at sexual debut compared to other early-maturing participants who did not get this type of maternal communication. This study extends the social cognitive learning theory to maternal socialization at menarche. Findings underscore the role of maternal communication in sexual development, especially for early-maturing girls. As such, this study provides new avenues for improving sexual and reproductive health outcomes in those currently worst affected, young adult women

    The influence of grazing macroinvertebrates on the structure of benthic diatom assemblages: Implications for biomonitoring.

    Get PDF
    Macroinvertebrates and diatoms are involved in the provision of many ecosystem services and are frequently used for monitoring ecological quality; indices being primarily based on community structure. Macroinvertebrate-induced changes in the structure of diatom assemblages have the potential to result in erroneous assessments of ecological quality by altering the value of biotic indices (e.g. Trophic Diatom Index, TDI) in the absence of change in environmental quality. The first aim of this thesis was therefore to determine how macroinvertebrate grazers, with different feeding modes, influence diatom assemblages. This was investigated in laboratory studies with artificial streams and via a field manipulation experiment. Mayfly grazers consistently decreased the relative abundance of high-profile diatoms, but the effect this had on the TDI was dependent on the relative sensitivity of the diatom species in the assemblage. Grazing induced changes in TDI, which were most pronounced when there was a significant difference in the average sensitivity of low-profile versus high-profile diatoms, has the potential to change the ecological quality assessment of a site, resulting in a possible misclassification. The second aim was to explore the relationships between biomass, diversity and composition of the diatom and macroinvertebrate assemblages in minimally impacted sites. This was investigated by surveying minimally impacted streams and assessing the response of macroinvertebrate and diatom assemblages to a major disturbance event (flood). No correlation was found between the diversity or ecological quality indices of the two groups. A higher biomass of periphyton (as Chlorophyll a) was associated with greater macroinvertebrate abundance and high-profile diatoms in the assemblage were positively correlated with the abundance of mayfly grazers, indicating some trophic links. Macroinvertebrate diversity and abundance decreased due to the flood but there was no consistent response from diatoms. Seasonality appeared to be more important in determining changes in macroinvertebrate community than a one off flood event. In conclusion, grazing macroinvertebrates (in particular mayflies) influence diatom assemblage structure by decreasing the relative abundance of high-profile diatoms, which can influence the TDI. Diatom and macroinvertebrate assemblages respond to different abiotic factors, as well as each other, and associations between them are not always detectable in the field (i.e. diversity). Assessments of ecological quality based on diatoms and macroinvertebrates were not concordant, meaning that one cannot be predicted from the other for monitoring purposes. Monitoring using both groups should provide better protection for the environment, as the lowest value can be taken, reducing the chance of false positives and provide greater understanding of how the system is functioning.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

    Brief on the future of non-MARC authority

    Get PDF
    The Indiana University PCC Non-MARC Authorities Issues Group was formed in response to the Program for Cooperative Cataloging’s (PCC) call for "
 a well-articulated plan as to how [a non-MARC authorities] future could work based on [ideas from the PCC community]." Of particular interest were ideas that could serve as a bridge "between an ideal world and what [catalogers] can do now to create [that world]." In this brief paper, the group proposes many changes that may ease the transition from MARC to library linked open data with a particular focus on authority data. The group outlines policy changes that may promote robust, granular data encoding practices and encourage the addition of meaningful linkages to FRBR Group 1 and Group 2 entities. In addition to forward-thinking policies and standards, our community is in need of a strong advocate for metadata curation systems. Having proper tools will enable catalogers to focus on the intellectual activities associated with metadata creation, curation, and strategy

    The Genesis 12–19 (G1219) Study: A Twin and Sibling Study of Gene–Environment Interplay and Adolescent Development in the UK

    Get PDF
    The Genesis 12–19 (G1219) Study is an ongoing longitudinal study of a sample of UK twin pairs, non-twin sibling pairs, and their parents. G1219 was initially designed to examine the role of gene–environment interplay in adolescent depression. However, since then data have continued to be collected from both parents and their offspring into young adulthood. This has allowed for longitudinal analyses of depression and has enabled researchers to investigate multiple phenotypes and to ask questions about intermediate mechanisms. The study has primarily focused on emotional development, particularly depression and anxiety, which have been assessed at multiple levels of analysis (symptoms, cognitions, and relevant environmental experiences). G1219 has also included assessment of a broader range of psychological phenotypes ranging from antisocial behaviors and substance use to sleep difficulties, in addition to multiple aspects of the environment. DNA has also been collected. The first wave of data collection began in the year 1999 and the fifth wave of data collection will be complete before the end of 2012. In this article, we describe the sample, data collection, and measures used. We also summarize some of the key findings to date

    Associations of sperm telomere length with semen parameters, clinical outcomes and lifestyle factors in human normozoospermic samples

    Background Many studies have demonstrated that lifestyle factors can affect sperm quality and fertility. Sperm telomere length (STL) has been reported as potential biomarker or sperm quality. However, no studies have investigated how lifestyle factors can affect STL and associated clinical outcomes. Objectives The purpose of this manuscript is to investigate any association between STL with lifestyle factors, semen parameters and clinical outcomes. Materials and methods Sperm telomere length was measured using real‐time PCR in normozoospermic male partners (n = 66) of couples undergoing ART treatment. Each participant also completed a detailed questionnaire about general lifestyle. Linear regression univariate analysis and ANCOVA were performed to respectively determine correlations between STL and study parameters or identify statistically significant differences in STL while controlling for age, BMI and other factors. Results Using a linear regression model, STL is positively correlated with in vitro fertilization success (n = 65, r = 0.37, P = .004) but not with embryo cleavage rates and post‐implantation clinical outcomes including gestational age‐adjusted birth weight. No associations were observed between STL and sperm count, concentration or progressive motility. We further found that STL did not associate age, BMI, health or lifestyle factors. Discussion In somatic cells, the rate of telomere shortening is influenced by a number of lifestyle factors such as smoking, diet and occupation. However, little is known about how lifestyle factors affect STL and subsequently reproductive outcome. Out data suggest that STL might have an important role mechanistically for fertilization rate regardless of sperm parameters and lifestyle factors. Conclusion The results of this study demonstrate that STL is associated with in vitro fertilization rates, but not with semen parameters nor lifestyle factors. Further investigations are warranted to identify the potential variation of STL overtime to clarify its significance as a potential biomarker in ART

    Are some interoceptive sensibility components more central than others? Using Item Pool Visualisation to understand the psychometric representation of interoception

    Interoception refers to the processing of stimuli originating within the body and is widely considered a multidimensional construct. However, there remains a lack of consensus regarding the definition and measurement of the subjective, self-reported component, referred to here as interoceptive sensibility. As a contribution to knowledge on the topic, we sought to examine the construct commonality and distinguishability of seven self-report measures of interoceptive sensibility using Item Pool Visualisation (IPV), an illustrative method that locates item pools from within the same dataset and illustrates these in the form of nested radar charts. Adults from the United Kingdom (N = 802) completed seven measures of interoceptive sensibility, and the data were subjected to IPV. Results demonstrated that, of the included measures, the Multidimensional Assessment of Interoceptive Awareness-2 provided the closest and most precise measurement of the core interoceptive sensibility construct (i.e., core of the entire investigated item pool). The Body Awareness Questionnaire and the Private Body Consciousness Scale were also centrally located measures, while the Body Perception Questionnaire and the Body Responsiveness Scale appear to tap more distal aspects of the core construct. We discuss implications for interpreting complicated data patterns using measures of interoceptive sensibility and, more generally, for measuring the construct of interoceptive sensibility
